An investigation into the proximate, mineral and antinutitional constitutents of natural cocoa powder (NCP), natural cocoa liquor (NCL) and alkalized cocoa powder (ACP) was carried out. Other parameters investigated were: energy values as contributed to the total metabolisable energy by protein, fat and carbohydrate and the energy percentages; calculated mineral quality parameters; mineral bioavailability as predicted by Ca: Phy, Phy:Zn and CaPhy/Zn molar ratios of the different cocoa products and mineral safety index (MSI) of some of the minerals of the samples. The data generated were subjected to statistical evaluation of chi-square (χ2). The three samples, NCP, NCL and ACP had proximate levels (g/100g) as: total ash, 3.73-10.8; moisture, 2.16-9.04; protein, 10.9-24.3; fat, 4.93-56.0; fibre, 1.03-17.3; carbohydrate, 20.5-48.9 and fatty acid, 3.95-44.8. For total energy contribution, results varied from, 1169-2656 kJ/100 g. In the minerals, the followings were higlhly concentrated: Na, K, Ca, Mg, Zn, Fe and P but low or not detected in Cu, Co and Mn. Virtually all the mineral quality parameters were poor as seen in these ratios: K/Na, Na/K, Ca/P and K/(Ca + Mg). The molar ratios of the samples were good enough to predict the bioavailability of the minerals. The mineral safety index (MSI) values showed that no mineral reached the toxic level in any of the samples. In the antinutritional constituents, ACP was highest in phytin phosphorus (Pp), phytin and Pp % of P; NCL was highest in oxalate and total phosphorus (P); tannin was highest in NCP. χ2 was significant in all proximate values (except ash, moisture and organic matter); all energy contributions, significant only in Mn (among the minerals); non was significant in the mineral quality parameters; only Ca: Phy was significant in the mineral molar ratios; no value was significant in the MSI and phytin was the only parameter significant among the antinutritional constituents.

Random Forest Classifier for Respiratory Mortality Analytics

Jun 2026 DOI 10.14302/issn.2642-9241.jrd-26-6332

Respiratory diseases remain a major contributor to hospital morbidity and mortality worldwide, particularly among elderly patients and individuals with severe pulmonary compromise. Accurate prediction of respiratory mortality is clinically important for triage, resource allocation, ICU utilization, and early intervention. Traditional statistical models frequently demonstrate limited predictive sensitivity because respiratory mortality is influenced by complex interactions among demographic, diagnostic, physiologic, and severity-related variables. In this study, a machine learning framework was developed to predict in-hospital mortality among patients with respiratory disease using administrative and clinically derived variables, including age, sex, length of stay (LOS), diagnostic descriptions, risk of mortality and severity scores. A Random Forest classifier with balanced class weighting was developed and implemented to address nonlinear relationships and class imbalance within the dataset. Initial modeling demonstrated good overall discrimination performance, with receiver operating characteristic area under the curve (ROC-AUC) values approaching 0.84; however, mortality recall remained limited because deceased patients represented a minority class within the original dataset. To improve mortality detection, a physiologically informed synthetic augmentation strategy was developed. Synthetic clinical variables included oxygen saturation, ICU status, ventilator support, sepsis status, systolic blood pressure, creatinine, and lactate levels. Conditional physiologic consistency rules were incorporated during augmentation to preserve clinically plausible relationships among respiratory failure, hemodynamic instability, and organ dysfunction. The augmented dataset substantially improved model sensitivity and balanced mortality classification performance. Final model evaluation demonstrated strong predictive capability, achieving approximately 97% classification accuracy with balanced precision and recall across mortality classes. Confusion matrix analysis revealed marked reduction in false-negative mortality predictions compared with baseline modeling approaches. Feature importance analysis identified physiologic instability markers, respiratory severity classifications, LOS, and diagnostic respiratory categories as dominant predictors of mortality. These findings suggest that hybrid simulation-augmented machine learning frameworks may provide a valuable strategy for respiratory mortality analytics, particularly in datasets with limited real-world mortality prevalence and incomplete physiologic representation.

Apomorphine Subcutaneous Infusion is More Efficient Than foslevodopa/foscarbidopa Subcutaneous Infusion in the Treatment of Advanced Parkison´s Disease for the Spanish National Health System

May 2026 DOI 10.14302/issn.2641-4538.jphi-26-6161
J GonzalezCorresponding author

Objectives Motor fluctuations and non-motor disorders not manageable by first-line treatments in advanced Parkinson's disease require continuous dopaminergic stimulation strategies such as subcutaneous infusions of apomorphine (APO) or foslevodopa/foscarbidopa (FLD/FCD). A Budget Impact Analysis (BIA) was performed to estimate the cost difference between both treatments assuming equivalent clinical efficacy and safety. Material and methods The efficacy results of pivotal clinical trials at 12 and 52 weeks of treatment and the safety profile of APO vs FLD/FCD were compared, based on latest scientific publications and other available clinical data. A comparative BIA was performed, based on estimated annual drug treatment costs at Spanish published prices. Results The efficacy of APO (16 h/day) and FLD/FCD (24 h/day) in reduction of OFF hours (2.47 vs 2.75, 12 weeks; 3.66 vs 3.50, 52 weeks; respectively) and increase of ON hours without disabling dyskinesias (2.77 vs 2.72, 12 weeks; 3.31 vs 3.80, 52 weeks; respectively) could be considered clinically equivalent, as well as their safety profiles. However, a significant discrepancy is observed in the costs of the aforementioned alternatives. Considering published prices and the average dose reported in the literature, in Spain the annual cost of APO would be €13,980 compared to €55,198 for FLD/FCD. Consequently, the financial resources required for the treatment of FLD/FCD would enable the treatment of approximately three to four patients with APO. The BIA indicated the potential for annual savings in more than €2,500 million, considering a total target population of over 60,000 patients per year. Finally, an univariant sensitivity analysis was performed, considering a scenario in which the hospital acquisition cost of FLD/FCD decreased between 20%-30% (€44,159- €38,638/year). In this scenario, the total annual savings range between €1,875-€1,532 million per year. Conclusions Overall APO is more efficient than FLD/FCD, as it provides similar clinical efficacy at a lower treatment cost. The selection of an appropriate treatment option is to be determined by clinical criteria and patient characteristics, but cost evaluation should be considered to select the most cost-effective therapeutic option.

Climate Change Sustainable Net-Zero Emissions by Uptake Atmospheric Carbon Dioxide by Terrestrial and Aquatic Plants

May 2026 DOI 10.14302/issn.3070-3379.jwc-26-6201
R. Hodgson BruceCorresponding author

A sustainable global net-zero carbon emission is when emissions are equivalent to the uptake of carbon by global terrestrial and aquatic plants. To meet that objective, an approximate 50% reduction of fossil-fuel emissions was estimated for net-zero by 2050 using carbon dioxide concentrations and mass emission monitoring by NOAA and related references. From that data, the initial target level of reduction to obtain net-zero was selected for year 2000 to minimise effects of climate change on environmental damage. The recent finding that about half global emissions are taken up from the atmosphere and increases global terrestrial and aquatic plant growth, including agriculture plants for food production, indicates it is important to maintain the year 2000 levels in the atmosphere. It was concluded as renewable energy was found to need support, it could be supplemented by electricity production remaining after obtaining net-zero, which also supports the atmospheric carbon dioxide levels for their important global ecological contribution.

A Decision Tree Ensemble Approach to Diabetes Prediction using the Framingham Heart Dataset, Exploring the Role of AI-Associated Interventions in Reducing Diabetes-Related Adverse Outcomes Between Men and Women

Dec 2025 DOI 10.14302/issn.2641-4538.jphi-25-5886
Y. Talbert PatriciaCorresponding author

Objective Diabetes poses significant public health challenges, with many individuals remaining undiagnosed and at risk of complications. This study aimed to evaluate the performance of decision tree ensemble methods for predicting diabetes onset using the Framingham Heart Study Teaching Dataset and to explore sex-specific risk patterns relevant to AI-driven interventions. Methods We analyzed data from 11,627 participants, incorporating demographics, vital signs, smoking status, medication use, and laboratory measures. Random Forest classifiers were developed to predict diabetes incidence at approximately 6-year (Period 2) and 12-year (Period 3) follow-ups. Class imbalance was addressed using undersampling, oversampling, and the Synthetic Minority Over-sampling Technique (SMOTE). Results The models demonstrated robust performance, achieving an Area Under the Curve (AUC) of 0.856 in Period 2, and moderate predictive ability in Period 3 (AUC = 0.732 in males, 0.786 in females). Key predictors included glucose level, BMI, systolic blood pressure, age, and heart rate. Notably, differences emerged in predictive accuracy between men and women, suggesting potential sex-specific vulnerabilities that merit further study. Conclusion Machine learning approaches, particularly Random Forests, show promise for medium- and long-term diabetes risk prediction, supporting early identification and intervention efforts. Future work should focus on hyperparameter tuning and explainability techniques, such as SHapley Additive exPlanations (SHAP) values, to improve model precision, interpretability, and fairness. Equity-focused strategies remain critical to ensure AI-driven tools benefit diverse populations and do not exacerbate existing disparities in diabetes care.

Uptake of Cervical Cancer Screening and Its Determinants among Refugee Women in Uganda: Insights from the Uganda Refugee Population-based HIV Impact Assessment

Dec 2025 DOI 10.14302/issn.2997-2108.jcc-25-5518
Steven KikonyogoCorresponding author

Cervical cancer is the fourth most common cancer in women globally, with 660,000 new cases and 350,000 deaths in 2022. The burden is disproportionately high in low- and middle-income countries (LMICs), particularly sub-Saharan Africa. Despite proven interventions like HPV vaccination and screening, uptake remains low. While cervical cancer screening has been studied in the general population, little is known about uptake among refugee women in Uganda, which hosts approximately 1.7 million refugees. This study examines cervical cancer screening uptake and associated factors among refugee women in Uganda. Methods We conducted a cross-sectional secondary analysis of the 2021 Uganda Refugee Population-based HIV Impact Assessment (RUPHIA) survey, focusing on women aged 21–49 in refugee settlements in the West Nile and South-Western regions, which host 90% of Uganda’s refugee population. The primary outcome was self-reported cervical cancer screening status. We used descriptive statistics and logistic regression to identify factors associated with screening uptake. Results Among 731 women, only 72 (9.8%) reported undergoing cervical cancer screening. The mean age of screened women was 37 years (±7), compared to 32 years (±8) for unscreened women. Screening uptake was significantly higher among women aged 31–39 years (AOR = 2.67, 95% CI: 1.32–5.52, p = 0.007), married women (AOR = 12.0, 95% CI: 1.76–163, p = 0.03), and those in polygamous relationships (AOR = 4.76, 95% CI: 1.96–11.1, p < 0.001) Conclusion Cervical cancer screening uptake among refugee women in Uganda is critically low. Integrating culturally sensitive screening programs into refugee health services and addressing socio-economic barriers could improve access and utilization.

Learning and Memory in an Animal Model of Longevity: The Ames Dwarf Mice

Oct 2025 DOI 10.14302/issn.3070-2313.jeh-25-5757
P. Austin DavidCorresponding author

The Ames dwarf mice have a recessive mutation of the PROP-1 gene that produces hereditary dwarfism. The abnormality is responsible for an anterior-pituitary deficiency that results in a substantial reduction of growth hormone, thyroid-stimulating hormone, and prolactin. These mice are smaller in size than their normal siblings but live approximately twice as long. The normal siblings do not have the mutation, and therefore still have the typical levels of the three hormones. The purpose of the present research was to determine if the reduced hormones in the Ames dwarf mice affected their ability to learn and delayed the age-related loss of memory. In general, the hypotheses proposed indicate that there will be no significant differences on the tasks in regards to the genotype or the age of the mice. These hypotheses would support previous research and suggest a delay in the age-related loss of memory and the ability to learn in the Ames dwarf mice. Learning was assessed using a matching-to-sample procedure, while memory was evaluated using a modified radial-arm procedure. Generally, the age of the animals had little to do with their performance on any of the tasks. Taken together, the overall results showed no significant differences in accuracy between any of the groups of mice or a behavioral decline as the mice age. The present results are consistent with the theory of a delayed age-related behavioral decline in the Ames dwarf mice.

Kankindi PriscillieCorresponding author

Economic masculinity support is paramount in promoting women’s well-being through numerous ways, including enhancing access to healthcare, education, and financial freedom, hence fostering equitable distribution of household responsibilities. However, studies examining the relationship between economic masculinity support and women’s well-being have not been well established in existing research. This study evaluated the relationship between economic masculinity support and the well-being of married women in Luwero district, Uganda. This Cross-Sectional study was conducted among 382 married women aged 18 to 50 years of age, from selected villages in Luwero district. The outcome variable, well-being, was assessed using the Gender Empowerment Measure (GEM). Data were analyzed using the Pearson correlation coefficient and linear regression to ascertain the relationship between economic masculinity support and the well-being of women. The findings show a moderate positive association between economic masculinity support and women's well-being (r = 0.55, p < 0.0001). Regression analysis indicated that economic masculinity support had a significant predictive influence (β = 0.42, p < 0.01) on women’s well-being, accounting for approximately 30% of the variance in well-being outcomes (Adjusted R² = 0.30). Linking economic masculinity supports improved access to essential resources. These results highlight the crucial role of economic support in enhancing women’s welfare, while also emphasizing the need to address socio-cultural barriers to achieve lasting empowerment. The study underscores the significant role of economic masculinity in promoting married women’s well-being. Transforming economic masculinity into a framework of mutual support is essential for advancing gender equity and safeguarding women’s well-being globally

A Case of Postoperative Hematoma Mimicking Giant Hydrocele

May 2025 DOI 10.14302/issn.2641-5518.jcci-25-5522
Qureshi AbidCorresponding author

Background In adult males, non-communicating hydroceles are non fluctuant scrotal swellings that are formed when there is an imbalance of fluid secretion and absorption between the parietal and visceral layers of the tunica vaginalis. Giant hydroceles are a rare manifestation and have previously been classified as hydroceles that drain more than 1000 mL of fluid. In this report, we describe a case of a giant hydrocele requiring surgical management and highlight a review of the literature. Case Presentation A 34-year-old male presented with complaints of large right-sided scrotal swelling, accompanied by scrotal discomfort. Ultrasound of the right testicle revealed a large hypoechoic space with a complex collection and posterior displacement of the testicle, indicating a possible hydrocele. The patient was taken to the operating room for a right hydrocelectomy. Approximately 2 liters of fluid were drained from the sac.  Discussion Hydroceles are defined as straw-colored fluid collections within the parietal and visceral layers of the tunica vaginalis. Giant hydroceles, defined as fluid collections within the tunica vaginalis exceeding 1000 mL, are rare and the management of such cases is sparsely documented in the literature. While most asymptomatic fluid collections resolve spontaneously, larger collections with inflammatory changes within the testicular wall may require surgical intervention, either laparoscopic or open. 

Fecal Shedding, Antimicrobial Resistance and In Vitro Biofilm formation on Simulated Gallstones by Salmonella Typhi Isolated from Typhoid Cases and Asymptomatic Carriers in Nairobi, Kenya

S. Gunn* JohnCorresponding author

Typhoid fever, caused by the human restricted pathogen Salmonella Typhi, remains a major global public health concern. Even after successful treatment, approximately 3-5% of patients with typhoid fail to clear the bacteria within one year and become chronic carriers. Most typhoid carriers have gallstones in their gallbladder, and biofilm formation on gallstones is highly correlated with chronic carriage. This study’s goal was to identify asymptomatic typhoid carriers in an endemic setting in Kenya, and to compare acute versus chronic isolates. A cohort of typhoid fever patients identified through blood and/or stool culture, and their household contacts, were followed up after treatment to detect longitudinal S. Typhi stool shedding. An abdominal ultrasound scan was used to identify individuals with gallstones. A total of 32 index patients and 32 household contacts were successfully followed-up. Gallstones were detected in 4 cases and 1 household contact. The duration of S. Typhi shedding was significantly longer in individuals with gallstones compared to those without, P<0.001. Eighty-three (83) S. Typhi strains were tested for susceptibility to commonly used antimicrobials and examined by in vitro biofilm formation assays. Out of 37 infected individuals, 32.4% had infections caused by multidrug resistant (MDR) S. Typhi strains and only 18.9% were infected by susceptible strains. Non-MDR strains formed significantly better biofilms in vitro than the MDR strains (P<0.001). This study provides data on S. Typhi chronic carriage that will influence public health approaches aimed at reducing typhoid transmission and the burden of infection.

Measuring Quality Change in the Market for Anti-Ulcer Drugs

Haider RehanCorresponding author

The General Accounting Office released a study in August 1992 of twenty-nine sampled prescription drugs that reported an average increase in the price of approximately 138 percent between 1985 and 1991 (GAO 1992, 4, Table 1) Those and other published price indexes are increasingly being used in the public policy arena to focus the debate on the potential regulation of pharmaceutical prices and the coverage of health insurance. In an industry where products are multidimensional and the rate of technological progress is brisk, misinterpretation of unadjusted indices of drug prices can easily arise. This can lead to erroneous conclusions regarding appropriate policies for the pharmaceutical industry. Researchers have addressed numerous general theoretical issues concerning the construction and interpretation of price indices 1. Two issues of particular interest for pharmaceutical markets are the new goods problem, which deals with the introduction of generic drugs into a drug price index, and the quality problem, which recognizes that newer versions of drugs with the same basic Chemical action may be superior in certain dimensions to drugs already on the market. Specific to pharmaceutical markets, 2 have also argued that the sampling procedure used by the Bureau of Labor Statistics to calculate pharmaceutical price indices is flawed. Each of those problems deserves careful analysis. This study focuses on the issue of product quality measurement and quality change.

RETRACTED: Leap into Fetal Surgery; In Utero Placental Mesenchymal Stem Cell Therapy, A Contemporary Approach to Treating Myelomeningocele

Apr 2024 DOI 10.14302/issn.2997-2086.jfs-23-4651
Osama Siddiqui MuhammadCorresponding author

This article has been retracted on April 10, 2025. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2997-2086.jfs-25-5857) Myelomeningocele (MMC), a class of spina bifida is a type of neural tube defect. According to the U.S. Centers for Disease Control and Prevention, each year approximately 1,400 babies born in the United States have spina bifida. The disease manifests with the lack of skin and bone covering the caudal part of the spinal cord. The patient developing such a condition often develops lifelong impaired lower limb mobility accompanied by hydrocephalus, and urinary and bowel incontinence. The available interventions include prenatal and postnatal surgery to fuse the dura. Prenatal surgery performed before 26 weeks of gestation reduces the risk of death or the need for ventriculoperitoneal shunting. It also enhanced results on a comprehensive index for mental and motor function. When compared to postnatal surgery, prenatal surgery reduces the manifestation of several secondary outcomes, including the degree of hindbrain herniation seen in the Chiari II malformation. Stem cell therapy for MMC on animal models of chick, ovine, and rodents with reported cases 15/63, 15, and 136, respectively, using human Embryonic Stem Cells (hESCs), Neural Stem Cells (NSCs), Mesenchymal Stem Cells (MSCs) showed significant coverage of MMC defect and slight neurogenesis was also observed. With an understanding of medical literature about in-utero regenerative capacity, it is to be appreciated that placental stem cells surgically seeded within a biocompatible scaffold of the cell patches can play a part in alleviating the spinal cord manifestation associated with MMC. Documented animal studies show that incorporating Placental Mesenchymal Stem Cells in prenatal surgery has reported improved neurogenesis and lower limb mobility. In an ovine myelomeningocele model, the development of in-utero myelomeningocele repair with human Placental Mesenchymal Stem Cells seeded onto an extracellular matrix (PMSC-ECM) enhances motor findings. The clinical trial for the first stem cell therapy on human subjects known as the “CuRe Trial: Cellular Therapy for In Utero Repair of Myelomeningocele.” is expected to be finished by 2030. So far, the cases undergoing treatment have shown significant leg movement and a greater degree of bowel and urinary control. This FDA-approved clinical trial is envisioned to be the future of treating MMC.

Yakubu SufyanCorresponding author

Promoting responsible energy usage in student hostels and residential buildings plays a crucial role in ensuring sustainable development. By implementing cost-efficient strategies for managing and conserving energy, both students and homeowners can not only reap economic and social benefits but also mitigate the adverse environmental effects associated with energy consumption. Unfortunately, student hostels and residential buildings in developing countries like Ghana are falling behind in the adoption of energy efficiency and management practices, thereby missing out on valuable implementation opportunities. This study investigates the potential for energy efficiency and conservation measures in student hostels, specifically the GETFUND hostel of the University of Energy and Natural Resources in Ghana. The hostel's monthly energy consumption is approximately 64,929.458kWh, which translates to $5,667.20. The objectives of the study include analysing the current electricity consumption pattern, identifying energy misuse, and recommending measures to save energy, as well as calculating the financial benefits of implementing energy management practices. The methodology employed is an energy audit approach. The results of this study can contribute to overall energy conservation efforts in Ghana and may be applied to other university residence halls in sub-Saharan African countries with similar climatic and energy-use characteristics. In a broader sense, the primary objective of this study is to enhance the energy efficiency of the GETFUND hostel and minimize energy wastage, resulting in substantial financial savings.

S. Mardanova KonulCorresponding author

Among the reproductive cancers cervical cancer has special place, because the second most frequent cause of cancer-related death among women worldwide. The studies suggested that the PI3K/mTOR/AKT signaling pathway is associated with certain reproductive tumors. A lot of research is ongoing for understanding this pathway evidence of its role in promoting tumorigenesis and recent progress in the development of therapeutic agents that targeted PI3K/AKT. In this a single-arm study included 34 Azerbaijan population woman with HPV-negative cervical tumors. The core genes of PAM signaling pathway were analyzed using RT-PCR method. Our preliminary results suggested that tumorgenesis of HPV-negative cervical cancer patients approximately 25% associated with dysregulation of PAM signaling pathway reason which are core genes alteration. The overall survival times in the PAM-active and PAM-stable patients were not significantly varies. However, the main factor for overall survival times were treatment strategy: both PAM-active and PAM-stable patients who received radiation therapy alone had a shorter overall survival than patients who received radiation plus chemotherapy. The patients with alteration of ATK1 and mTOR genes in PAM signaling pathway had poor prognosis then patients with PIK3CA and PTEN mutation

The Potential Usefulness of Peripheral Somatosensory Stimulation in Improving Sleep Quality in Patients with Insomnia

Feb 2024 DOI 10.14302/issn.2574-4518.jsdr-24-4949
Nussbaum LACorresponding author

Background Insomnia and other sleep disorders represent a major cause of disability and impaired productivity. We evaluated the impact of peripheral somatosensory stimulation (PSS) on sleep quality in 12 patients with varying degrees of insomnia. Methods Twelve adult patients underwent daily PSS therapy for a 4-week period and were evaluated using the Insomnia Severity Index at baseline (prior to initiation of therapy) and then at the conclusion of the treatments. All data were obtained through a self-reported 7-question survey evaluating overall severity of insomnia symptoms and the impact of sleep patterns on satisfaction with sleep, daily functioning, and overall quality of life. Changes from baseline insomnia scores were analyzed using cumulative link mixed models (CLMMs). Results Seven men and five women completed one month of PSS therapy. Mean age was 55.1 (range 29 to 80 years). No adverse events were described by the patients. The average total change from baseline score was -10.3 points (baseline: 16.5 vs. week 4: 6.2). Patients had statistically significant improvements for every individual survey question by week 4. The median composite score was improved from baseline, with an overall median score of 2 (IQR: 1.25 – 2.75, min-max: 1-4) at baseline compared to 0.5 (IQR: 0 – 0.25, min-max: 0-2) by week 4 (MD = -1 95% CI: , p < 0.001), signaling typically moderate insomnia at baseline vs. typically minimal to no symptoms by week 4. The predicted probability of obtaining the best outcome (score=0) was 9% at baseline vs. 53% by week 4. The overall cumulative odds ratio was 11.9 (p < 0.001), suggesting that on average, the odds of moving from one score to a lower (improved) score at week 4 compared to the baseline are approximately 12 times higher than moving to a neutral or worse score. Conclusions PSS stimulation appeared to have a significantly favorable effect on sleep quality in this group of patients. Symptoms related to ability to fall asleep, remain asleep, and overall quality of sleep were all improved with PSS therapy. We suggest that further investigation into the potential usefulness of PSS therapy in patients with sleep disorders is warranted.

Knowledge And Practice of Preconception Care Among Women of Reproductive-Age in Bheerkot Municipality, Nepal

Dec 2023 DOI 10.14302/issn.2381-862X.jwrh-23-4750
Godar MousamiCorresponding author

Background Preconception care is a crucial aspect of maternal and child healthcare services that aims to mitigate adverse pregnancy outcomes and enhance the desired health outcomes for women, newborns, and children. Despite the continuous multi-sectoral efforts in preconception care, maternal mortality and morbidity remain significant health concerns globally. This study aimed to assess the knowledge and practice of preconception care and its associated factors among women of reproductive age in Bheerkot Municipality, Nepal.  Methodology A community-based descriptive cross-sectional study was conducted among 215 reproductive-age women to assess knowledge and practice regarding preconception care in Bheerkot Municipality, Nepal. Structured questionnaires were designed in the Nepali language and used in face-to-face interviews. We used a simple random sampling technique to collect quantitative data. In a statistical analysis, we employed the Chi-squared test and logistic regression analysis to identify possible predictors using the odds ratio and considered variables with p<0.05 statistically significant at a 95% confidence interval. Result Out of the 215 women who participated in the study, only 46.9% had a good knowledge of preconception care. Approximately half (43.7%) of the respondents had never practiced preconception care. Among respondents who had practiced preconception care before, 47.9% reported good practice, and 52.1% reported poor practice. Age of the respondent (χ2=14.2063, P=0.000823, df=1), marital status (χ2=17.9851, P=0.000022, df=1), time to reach a health facility (χ2=30.1371, P=0.00001, df=1), and age at first pregnancy (χ2=4.7975, P=0.0285, df=1) were statistically associated with knowledge about preconception care. Women who have foreign employment as a major source of family income and whose age is from 25 to 34 years were more likely to have a better practice of preconception care than their counterparts (COR 3.5000, CI 1.3343 to 9.1805, P = 0.0109) and (COR 3.4000, CI 1.1646 to 9.9265, P = 0.0252), respectively. Additionally, out of those who practiced preconception care, most respondents (93.4%) have practiced it in government health facilities. Conclusion Respondents had relatively poor knowledge and practice of preconception care. Collaboration of governmental health institutions between multiple sectors at local levels for more education and information and a specific national protocol or policy formulation would be beneficial in improving preconception care in Nepal.

Human Immunodeficiency Virus Drug Resistance (HIVDR) and Baseline Characteristics among Antiretroviral Therapy (ART) experienced Children and Adolescents under the care of Chidamoyo Christian Hospital in Hurungwe, Zimbabwe

Makura AlfredCorresponding author

Introduction Human Immunodeficiency Virus (HIV) remains a persistent global public health challenge. In 2020, approximately 37.9 million individuals were living with HIV globally, including 1.7 million children <15 years old, with a global HIV prevalence of 0.8% among adults. A larger portion of people living with HIV are found in low-and middle-income countries, and Sub-Saharan Africa (SSA) is home to about 68% of people living with HIV in the world. Strikingly, with increased uptakes in PMTCT, challenges in ART programs, and high viremia among children and adolescents in SSA, the success rate of ART might be quickly compromised, with possible HIVDR emergence, particularly after years of paediatric ART exposure. Therefore, monitoring ART response in children and adolescents in terms of HIVDR patterns and other socio-economic determinants of disease progression might help achieve better treatment outcomes at individual levels. At a programmatic level, this can guide further optimization of treatment options for SSA especially Zimbabwean rural where there is paucity of information on HIVDR prevalence in children and adolescents. Methods We enrolled 89 children and adolescents experiencing virologic failure from Chidamoyo Christian Hospital in Hurungwe. We managed to amplify all the 89 using nested PCR and 32.5% (29) had resistance to at least one ART drug and analysis was done using the 29 samples. Results Among the 89 participants with virologic failure,29 were resistant to at least one of their ART drugs. 39.2% of males and 23.07% of females had HIV-1 with resistance to at least one medication. Among 29 participants with HIVDR mutations, the prevalence of at least one HIVDR mutation to protease inhibitors (PIs), Nucleotide Reverse Transcriptase Inhibitors (NRTI), and Non-Nucleotide Reverse Transcriptase Inhibitors (NNRTI) were 6.47% ,46.76% and 46.76% respectively. Of the 29 participants who had HIVDR 19 (65.5%) had resistance to a drug they were currently taking and they needed to be switched to a better effective ART regimen Conclusion Use of HIVDR testing in guiding and monitoring development of HIVDR at the start of ART or at 1st failure can be very important in treatment options and patient management.

G. Ong EmilyCorresponding author

This study explored concerns and unsolicited advice relating to miscarriage shared on multiple social media platforms for mentions of questions, advocacy, medical advice, conflicts of interest, and terminology used to describe miscarriage. Public social media posts in English from January 1st, 2019 to June 30th, 2021 were searched using keywords related to miscarriage. A dataset of questions, advice, conflicts of interest, and terminology used was created from eligible posts determined by inclusionary and exclusionary criteria. The dataset was analyzed to identify themes and calculate statistics. Approximately 1000 posts were reviewed and 149 posts were found eligible for analysis. Of the total, 116 posts included advice and a subset of 71 posts offered questions. A total of 152 mentions of advice were identified from the total eligible posts with 82.9% of advice related to advocacy for destigmatizing miscarriage, enhancing community support, or expressing grief. 17.1% of posts offered medical advice eligible for evaluation of which 73% were accurate across all platforms. From the dataset, 103 questions were analyzed for common themes. The four most common themes of questions included grief, self-blame, quality of post-miscarriage counseling in different care settings, and inadequate medical counseling.  This study indicates that women who experience miscarriage have many unanswered questions and powerful feelings relating to grief and self-blame that could have long-term impacts. Social media has become a place for women to self-advocate and connect with others for support, from which clinicians could increase their understanding of women’s unmet needs.

Background Nearly 40% of the adult population in the United States are considered obese by current standards, which equates to approximately 93 million people. Obesity is a chronic disease that is linked to more than 40 other diseases, including hypertension, heart disease, stroke, diabetes, and at least 13 distinct types of cancers. The direct and indirect costs of obesity have been estimated at up to $210 billion annually. Local Problem In Cumberland County, North Carolina, 34% of the adult population was considered obese. The aim of this quality improvement study was to increase effective care (screening, patient engagement, and referral to treatment) in adult patients with a BMI greater than 30 kg/m2 to 75% within 90 days. Methods A rapid cycle plan-do-study-act framework was used to evaluate four focus areas concurrently over 8 weeks with a small test of change completed in each 2-week cycle. Interventions An expanded screening with a checklist, shared decision-making tools (SDMTs), and a referral to treatment checklist were implemented. Activities from the team engagement plan were initiated. Results The effective care of patients increased by 42 percentage points while engaging both the patients and the staff. Conclusions Utilizing standardized communication, SDMTs, checklists, and management plans improved effective care while motivating and enabling patients to take control of their care and make sustainable lifestyle changes that enhance overall health.

Introduction Acute diarrhea remains one of the major health problems in developing countries. According to the WHO, rotavirus contributes to approximately 40% hospitalizations and is the leading cause of severe diarrhea in children 0-5 years old. The objective was to determine the prevalence of rotavirus and the sociodemographic and clinical profile among children with diarrhea in 4 hospitals in the DRC. Methods This study is documentary, retrospective and analytical taking two periods, before and after introduction of the vaccine, i.e. January 2017 to December 2018 and January 2020 to December 2021 in 4 hospitals, i.e. 2 in Kinshasa and 2 in Lubumbashi. Results Total 1872 children, 924 (49.4%) of whom were enrolled before the introduction of the vaccine and 948 (50.6%) after. Only 1737 had performed serology, of which 875 (50.4%) were rotavirus positive and 862 (49.6%) were negative. Positive results, a reduction of 30.6% is noted since the introduction of the vaccine. The predominant age range was 6 to 11 months. The male gender was predominant at 56.7%. Diarrhea was found in 88.5%, vomiting in 73.7% and fever in 73.9%. Before vaccination, the risk was more: 11 times to have diarrhea, 9-10 times the frequency between 3-10 times a day, 9 times vomiting, 2 times fever and 2 times to have a positive result. Conclusion From this study, we note a reduction frequency due to diarrhea unlike previous years, probably attributable to the vaccine.

Tunta AbaynehCorresponding author

Background HIV causes immunosuppression, which reduces the body's immunity to diseases like COVID-19 by decreasing CD4 cells. The goal of this study is to determine whether persons living with HIV/AIDS (PLWHA) who are using anti-retroviral therapy (ART) are willing to accept the Coronavirus illness 2019 vaccination and the factors that influence their decision. Method From February 15 to March 15, 2022, 332 PLWHA on ART participated in this facility-based cross-sectional study. The correlation of outcome variables with predictors was investigated using binary and multivariable logistic regression. Result Of the 332 study participants, 110 (33.1 %) and 118 (35.5 %) had poor knowledge and a negative attitude toward the COVID-19 vaccination, respectively. Approximately 31 (9.3%) of study participants believe ART medications can also prevent COVID-19 infection. The willingness to receive the COVID-19 vaccine was 66.3 % with a 95 % confidence interval (60.9, 71.5). Knowledge, attitude, educational status, marital status, residency, duration, and monthly income were all significant predictors of willingness to receive COVID-19 vaccination. Conclusion Increased sensitization regarding the necessity of vaccines and the negative consequences of diseases, particularly among PLWHA, should be emphasized in the preparation of the COVID-19 immunization campaign involving prominent individuals such as health professionals and religious leaders.

Vladimir ZaichickCorresponding author

Background Thyroid benign (TBN) and malignant (TMN) nodules are a common thyroid lesion. The differentiation of TMN often remains a clinical challenge and further improvements of TMN diagnostic accuracy are warranted. The aim of present study was to evaluate possibilities of using differences in trace elements (TEs) contents in nodular tissue for diagnosis of thyroid malignancy. Methods Contents of TEs such as silver (Ag), aluminum (Al), boron (B),, beryllium (Be), bismuth (Bi), cadmium (Cd), cerium (Ce), cobalt (Co), chromium (Cr), cesium (Cs), iron (Fe), gallium (Ga), mercury (Hg), iodine (I), lanthanum (La), lithium (Li), manganese (Mn), molybdenum (Mo), neodymium (Nd), nickel (Ni), lead (Pb), praseodymium (Pr), rubidium (Rb), antimony (Sb), scandium (Sc), selenium (Se), samarium (Sm), tin (Sn), thallium (Tl), uranium (U), yttrium (Y), and zinc (Zn) were prospectively evaluated in nodular tissue of thyroids with TBN (79 patients) and to TMN (41 patients). Measurements were performed using a combination of non-destructive instrumental neutron activation analysis with high resolution spectrometry of short- and long-lived radionuclides (INAA-SLR and INAA-LLR, respectively) and destructive method such as inductively coupled plasma mass spectrometry (ICP-MS). Results It was observed that in TMN tissue the mean mass fractions of Be, Fe, I, Sc, and Se are approximately 1.9, 1.7, 14, 3.1, and 1.6 times, respectively, lower while the mass fraction of Ga, Mo, and Rb 62%, 51%, and 33%, respectively, higher than those in TBN tissue. Contents of Ag, Al, B, Bi, Cd, Ce, Co, Cr, Cs, Hg, La, Li, Mn, Nd, Ni, Pb, Pr, Sb, Sm, Sn, Tl, U, Y, and Zn found in the TBN and TMN groups of nodular tissue samples were similar. Conclusions It was proposed to use the I mass fraction, as well as I/Ga, I/Mo, and I/Rb mass fraction ratios in a needle-biopsy of thyroid nodules as a potential tool to diagnose thyroid malignancy. Further studies on larger number of samples are required to confirm our findings and proposals.

Fernando Moreira Izidoro LuizCorresponding author Faculdade de Medicina, Universidade Federal de Uberlândia, Uberlândia, MG, Brazil.

Snake envenomations are responsible for a high percentage of deaths, as these toxic proteins induce severe local and systemic effects. In Brazil, the Bothrops genus is responsible for a satisfactory fraction of accidents, including Bothropsalternatus, recognized as urutu, whose venom is capable of inducing severe myotoxicity. In this work, the BaMtox toxin was purified through a combination of three chromatographic steps, ion exchange in DEAE-Sepharose, affinity in Benzamidine Sepharose 6B columns and reversed-phase HPLC chromatography on a C18 column. The BaMtox toxin has a molecular mass of approximately 14kDa and did not show phospholipase activity or hemorrhage. On the other hand, it induced edema and a significant increase in plasma levels of the creatine kinase enzyme. Thus, the protein called BaMtox is able to induce myotoxicity.

Background Human malignant cell models which reflect the structural and physiological complexity of tumor tissue are of great importance for preclinical research in oncology. Spheroids/tumoroids derived from solid tumors are of great interest as cellular models mimicking the first vascular-free growth phase of a tumor node. The fact of the identity between artificially created tumor multicellular aggregates and the real tumor tissue, however, needs to be specified, described and validated in order to see how closely the spheroids are biologically similar to the malignized tissues in vivo compared to the monolayer cell cultures traditionally used. We present here a comparison study of the characteristics of solid tumor cells of different histogenesis (melanomas, soft tissue sarcomas and bone sarcomas, epithelial tumors) cultured in two dimensions (monolayer culture) and three dimensional space (spheroid), namely: spatial organization, multiplication, metabolic activity. Patients and Methods For the creation of 2 D and 3D cell models the cells isolated from the patient's solid tumor fragments obtained intraoperatively were used. 15 samples of skin melanoma, 20 samples of soft tissue and osteogenic sarcomas (STBS), and 9 samples of epithelial tumors (ET). The tumor cells were all cultivated for at least 10 passages. We used phase contrast, confocal microscopy, and immunohistochemistry to investigate spheroids and monolayer cultures. The supernatants of tumor cells grown in 2D and 3D cultures were studied using ELISA and multiplex analysis for the production of a spectrum of chemokines and cytokines supporting the immunosuppression, invasion and metastasis processes. Results Tumor specimens received were predominantly of metastatic origin (75%). In 100% of cases 2D cultures were received, in 88.6% of cases (39 out of 44) we succeeded in obtaining spheroids. There was no direct correlation between the efficiency of tumoroid formation and the tumor's histogenetic origin and the stage of the cancer process (primary tumor, recurrence, metastasis). The median size of spheroids by 4-5 days of cultivation with a starting concentration of 10000 cells per well was 657.14 μm for melanoma (min 400 - max 1000 μm), 571.42 μm (min 400 - max 700 μm), 507.14 μm (min 300 - max 600 μm) for soft tissue sarcomas, 650.0 μm (min 400 - max 900 μm) for osteogenic sarcomas. Immunochemical analysis of Ki-67, GLUT1, and Ecadherin markers was carried out for tumor tissue samples, single-layer tumor cultures, and tumoroids of every patient. The distribution of the stained groups in the spheroids was distinct from the monolayer cultures and more in accordance with the distribution of such in the tissue tumor, the number of Ki-67+ cells was increasing in the spheroids. We detected no dependence of Ki-67+ and GLUT1+ cell localization grade on spheroid size. We identified E-cadherin in tumor tissue and tumoroids of breast carcinoma and one melanoma culture. Monolayer cultures did not express it. The increase in secretory cell activity of the solid tumor cells from 2D to 3D system was observed when CCL2, CCL3, CXCL1, CXCL16, MIF, IL10, MICA (p<0.01) were investigated. Conclusion The presence of patient-specific cells of solid tumors in a 3D environment causes activation of the proliferative and metabolic processes as compared to monolayer cultures, which makes these models approximate the real world clinical picture. The production of chemokines that can attract to the tumor various types of immune system cells, to include their immature versions, as well as production of cytokines and Immunosuppression factors that, when present in the tumor microenvironment in the high concentrations, contribute to the formation of immune cells having suppressive capacities occurs in the 3D cell system. Three-dimensional model of the initial tumor nodule formation stage thus demonstrates the forming process of tumor cells favorable for them microenvironment. Construction of three-dimensional models - spheroids of tumor cells of differing histogenesis demands individual approach and more thorough investigation.

Background As COVID-19 immunomodulation has been a part of interest for studies, it has been found that severe coronavirus disease 2019 (COVID-19) is associated with hyper-inflammatory response and increased levels of interleukin-6 (IL-6) and interleukin-10 (IL-10). This can progress to cytokine storm syndrome and eventually development of acute respiratory distress syndrome (ARDS). Interleukin-1 receptor antagonist (IL-1RA) is a protein that is a member of the interleukin 1 cytokine family. Monocyte chemoattractant protein 1 (MCP1) is a small cytokine that belongs to the CC chemokine family. Interferon gamma-induced protein 10 (IP-10) is a protein secreted by several cell types in response to Interferon-Gamma (IFN-γ). All of these have roles in the immune response and eventually development of a cytokine storm. Methods Serum levels of IL-1RA, MCP-1 and IP-10 were measured in a cohort of 21 patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on admission to a tertiary care hospital in Riyadh, Saudi Arabia, as well as in an approximately age-sex matched group of 4 uninfected controls. The study population was classified into severe, moderate, mild and controls. Results Serum levels of IL-1RA, MCP-1 and IP-10 were found to be elevated before the clinical deterioration. Conclusion These cytokines may play a role in early detection of disease severity especially in the pre-storm phase. Medications that target cytokines may prevent the development of an overt cytokine storm.

Pino Marrero KatiaCorresponding author Holguin's university of medical sciences, Cuba.

Vaccines symbolize the main pandemic control tool in the world, which is why they are the object of study in many investigations. In this work, the Abdala vaccine was characterized in terms of adverse reactions by conducting a survey and statistical processing of the data taken through distribution graphs of the same, developed in the Minitab software 16. Of the people involved, 47.67% presented Symptoms that were mild to moderate with the presence of pain in the area of the injection, drowsiness and decay, mainly. Based on the distribution of the data in histograms, the duration of these symptoms was approximately 1 day. Likewise, it was observed that the symptoms occur mainly in females, for 33.72% of the cases in the first dose and 23.26% after the second dose was applied.

Prolonged Thrombin Time in Asymptomatic Patient with Hypo Dysfibrogememia Tucson

Aug 2021 DOI 10.14302/issn.2372-6601.jhor-21-3903
B Katakkar SureshCorresponding author Arizona Hematology Oncology, Tucson Arizona USA

A 61 years female patient with known diagnosis of the breast cancer in remission for more than 10 years has Renaud’s disease. During her work up for lupus and lupus anticoagulant which both were negative a prolonged thrombin time was noted which was done by mistake. She has no history of bleeding or thrombosis and last recent surgery was 5 years ago for spinal stenosis and was uncomplicated. Her clinical examination is normal without evidence of any spontaneous bruises but colder hands. The thrombin time was greater than 125 seconds on two different occasions and correction of it by addition of normal plasma was down to 56 seconds and was thus incomplete. Her prothrombin time and PTT were normal and there was no evidence of FDP or D-Dimers. There was no evidence of circulating heparins. The fibrinogen level was normal. The para proteinmia was excluded by normal serum protein electrophoresis and by immunofixation . Thus it is felt that this patient has dysfibrinogenemia or hypo dysfibrinogenemia without bleeding or thrombotic complication. The literature review shows approximately 55% of dysfibrinogenemia patients do not have bleeding or thrombotic complications.

A Model-Based Estimation of Annual Long-Term Care Costs in Germany Following Post-Operative Cognitive Dysfunction (POCD) in Elderly Patients

Acute post-operative delirium (POD) and long-term post-operative cognitive dysfunction (POCD) are frequent and associated with increased mortality, dependency on care giving and institutionalization rates. The POCD-related cost burden on the German long-term care insurance provides an indication for the savings potential from risk-adapted treatment schemes. Comprehensive estimates have not been assessed or published so far. A model-based cost-analysis was designed to estimate POCD-related costs in the long-term care insurance. Comprehensive analysis of inpatient operations and procedures (OPS-codes) served as the base for case number calculations, which were then used as input to the actual cost model. POCD-incidence rates were obtained from the BioCog study. Various sensitivity analyses were performed to assess uncertainty of the model results. Total POCD related annual costs in the German long-term care insurance account for approximately 1.6 billion EUR according to the base case of our analysis. Total annual costs for all POCD cases depend on surgery numbers, incidence rates, other assumptions, and uncertain input parameters. The financial burden to the long-term care insurance is substantial, even in a conservative scenario of the cost model. Variability of results stems from uncertain assumptions, POCD-incidence rates and from uncertain patient numbers who are undergoing surgery and are therefore at risk to develop POCD.

A Predictive Tobacco Control Mass Media Programming Model to Achieve Best Buys in Low –and Middle-Income Country Settings

Dec 2020 DOI 10.14302/issn.2641-4538.jphi-20-3641
Turk TahirCorresponding author

Background Evidence based message design and efficient dissemination of messages are critical to the success of tobacco control mass media campaigns. Although evidence to measure effectiveness of messages is emerging within low -and middle-income country (LMIC) settings, evidence-based approaches for mass media message dissemination is currently lacking due to challenges in accurate assessment of gross rating points (GRPs) for efficient delivery of campaign messages. Approaches to more accurately predict optimal campaign impact are required to achieve best-buys in resource constrained settings Method A case study approach compared findings from two national tobacco control mass media campaigns implemented in Bangladesh. Stage one reviewed protocols to assess the efficacy of message designs. Second stage analysis involved a review of the mass media campaign recall findings from cross-sectional, post-intervention surveys. Last, a post assessment of GRPs for both campaigns was conducted to support the development of an algorithm to better predict campaign impact at the greatest cost-efficiencies. Results Message mean pre-test scores identified that the Baby Alive campaign scored approximately 20% lower than mean pre-test scores of messages for the Graphic Health Warning campaign. Media dissemination for the Baby Alive campaign was also relatively low at 165GRPs achieving 16.8% prompted recall while the Graphic Health Warning campaign delivered 292GRPs to achieve 47.0% prompted recall. The analytic-predictive model identified that for messages with high pre-test scores an increase of only 1.5GRPs was required to the existing media plan to potentially achieve an additional percentage point of recall. Discussion Given the weaknesses in GRP calculations in LMIC settings, analysis of multiple metrics should be considered to achieve best buys for tobacco control mass media campaigns. Based on optimal message mean pre-test scores of 90%+ and delivery of 292GRPs, which achieved 47% campaign recall, optimal recall of 70% could be predicted with a media plan delivering 342GRPs. More analytical-predictive mass media programming models need to be developed in other LMIC settings examining multiple campaign findings to confirm if this algorithm can provide better returns on investment with efforts directed toward delivering interventions that are supported by a strong evidence base.

Alghamdi MohammedCorresponding author Infectious disease consultant, King Fahad General Hospital

Background The use of hydroxychloroquine in coronavirus disease (COVID-19) pandemic raised significant concerns as regards safety and efficacy in hospitalized patients. The objective was to examine the effect of hydroxychloroquine on clinical improvement and mortality among hospitalized patients with COVID-19. Methods A prospective cohort study was conducted at four general hospitals in the Western region, Saudi Arabia. Patients who had absolute or relative contraindication for using hydroxychloroquine were excluded. Patients concomitantly receiving other medications including azithromycin, antivirals, and supportive treatment were not excluded. Results A total 267 patients were included in the current analysis; 185 (69.3%) on hydroxychloroquine and 82 (30.7%) on non-hydroxychloroquine treatments. The average age was 46.0±13.3 years and 78.3% of the patients were males. Approximately 95.9% of the patients were symptomatic with mild (50.6%), moderate (32.6%), severe (8.2%), or ARDS symptoms (4.5%). Compared with no hydroxychloroquine, those on hydroxychloroquine had significantly longer length of stay (11.5±7.1 versus 7.8±4.3 days, p<0.001), more ICU admission (22.7% versus 9.8%, p=0.012), and more intubation (12.4% versus 3.7%, p=0.026). Improvement of symptoms (84.3% versus 81.7%, p=0.595) and hospitalization death (7.0% versus 1.2%, p=0.071) were not significantly different between groups. With exception of length of stay, the association of hydroxychloroquine with the above negative outcomes disappeared after adjustment for several factors including disease severity and concomitant use of azithromycin. Conclusions Hydroxychloroquine is not associated with better improvement of symptoms compared with other treatments. Moreover, it is associated with longer length of stay but not mortality or ICU admission in adjusted analysis.

Conversion of biomass into fermentable sugars is a major requirement for successful and cost-effective biofuels production. The conversion of xylan to sugars requires multiple enzymes including α-glucuronidase. Here we report the cloning, expression, purification and characterization of the α-glucuronidase from Dictyoglomusturgidum(DtuAgu). DtuAgu is an intracellular protein of 685 amino acids and a predicted molecular weight of 79.4 kD. Enzymatic activity was optimum between pH 7.0 and 8.0 and at 85°C. The specific activity of the enzyme was 10 u/mg when measured using mixed aldouronic acids. The specific activity on isolated glucuronoxylan was approximately 20% of the value obtained with xylooligosaccharides. DtuAgu significantly improved xylan conversion to xylose when evaluated using two mixtures of thermostable bacterial enzymes and two sources of xylan. DtuAgu has the potential to be a key player in thermostable enzyme cocktails for the conversion to biomass to biofuels.α

Spices have been frequently added to foods since ancient times, not only to enhance the taste but also as preservatives and medicinal agents. Their usage may be of concern due to possible contamination during processing and handling. The aim of this study was to investigate the physicochemical properties and heavy metals concentrations in some indigenous spices sold at two main markets namely Bodija and Apata markets in Ibadan, Oyo State, Nigeria. A total of eight commonly consumed spices were purposely analyzed for their proximate and mineral composition, physicochemical properties and anti-nutrients contents. Proximate analyses showed that the spices to contained (fresh matter ‘As consumed’) moisture content ranging from 11.74g in thyme to 59.36g/100g in scent leaves. Crude protein, fat, fibre, ash and carbohydrate contents ranged between 3.72 – 15.07g, 1.31 – 8.28g, 1.96 – 11.38g, 1.11 – 7.81g, and 17.80 – 50.77g/100g sample, respectively. All the spices contained high levels of potassium (176.3 – 739.6 mg), sodium (60.6 – 317 mg), calcium (78.5 – 423.9 mg), magnesium (82 – 322.1 mg) and iron (5.78 – 20.10 mg), but low levels of heavy metals – copper (0.17 – 0.68 mg), and manganese (0.32 – 1.05 mg)/100g respectively. Flavonoid was the most abundant phytochemical, while terpene was the least phytochemical in all the samples. The samples had very low concentrations of anti-nutrients, and could pose no threat to human health, as their values were within the regulatory standard. The antioxidants and phytochemicals in the spices can help in building up immunity and prevention of non-communicable diseases, hence, their consumption should be encouraged.

Electrical resistivity method is often used to estimate the subsurface structure of the earth. Many inversion algorithms are available to estimate the subsurface features. However, predicting the exact parameter in the non-linear subsurface of the earth is difficult because of its complex composition. Soft computing tools can approximate the subsurface parameters more clearly. Each soft computing tool has certain advantages and disadvantages. A hybrid formation of algorithms will make the decision more appropriate than depending on a single tool. Here in our study the data obtained through Vertical Electrical Sounding has been used to determine the sub surface characteristics of earth viz., true resistivity and thickness. Artificial Neural Networks (ANN) requires certain optimizing procedures. Here in this paper, Genetic Algorithm (GA) is applied to optimize Artificial Neural Networks (ANN). This coupled approach is tested with the field data. Error percentage of algorithm nearly mimics the behavior of earth and is verified. The best performance result shows that this technique can be implemented to estimate the non-linear characteristics of the earth more noticeably.

An 84 day feeding trial was conducted on the juveniles (42.51±0.09g) of hybrid catfish, Heteroclarias, in order to evaluate the nutritional potential of 30 minutes autoclaved castor seed cake isonitrogenous (40% crude protein) and isocaloric (3212Kcal/Kg) diets replacing soybean meal at 0, 12.5, 25, 37.5 and 50%, the diets being designated D1, D2, D3, D4 and D5 respectively. Prior to this, the castor seeds (Ricinus communis L.), ZiboCastor No. 3 variety, collected from Ado-Ekiti metropolis, Nigeria were subjected to 0, 20, 30 and 40 minutes autoclaved at 121oC, dehauled, grounded, oil extracted to form cake, then the proximate and antinutrients analysis were carried out. The preliminary tests on the seeds revealed 30 minutes level of autoclaved seeds was the best. The growth performance result showed that there were significant differences (p<0.05) in the mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) and apparent net protein utilization (NPU) among the various diet levels with the progressive decline in the values of each parameter (except FCR that showed progressive increment) along the trend of increment of castor seed cake inclusion (D1, 0%; D2, 12.5%; D3, 25%; D4, 37.5% and D5, 50%). The survival rate followed the same trend of declination with the highest percentage recorded for D1 (93.33±6.67%), followed by D2 (83.33±3.33%), D3 (76.57±3.33%), D4 (66.67±3.33%) and D5 (60.00±5.77%) respectively. Hence the best growth performance and nutrient utilization was shown in D1 (control) followed by D2. It is therefore recommended that autoclaved castor seed cake at 121oC be included at not more than 12.5% inclusion level to reduce cost of feed without necessarily compromising fish growth rate.

Benzene is known as an environmental and industrial pollutant. One way to check the amount of exposure to benzene is to measure its metabolites in the urine. Trans, Trans-Muconic Acid which is one of its metabolites is also as a biological indicator of exposure to benzene. In this study, the relationship between the amount of this biomarker and the environmental benzene concentration was investigated in two groups of policemen working outdoors in the traffic-congested areas and indoor in the same area. The results showed that the highest amount of benzene was in Salman Farsi Station at 4.44 ppm. At the same time, the biomarker measured in the urine showed 127.20 μg / L, which was the highest amount. In addition, the amount of benzene in the outdoor was approximately 3 times more than indoor and the amount of biomarker measured in outdoor employees was two times more than indoors ones. In general, wherever there was more benzene, the biomarker would also show a higher amount.

RESinvANFIS v1.0 - A Versatile MATLAB Tool for Inverting Geoelectrical Resistivity Sounding Data using Neuro Fuzzy Technique

Apr 2020
Stanley Raj A.Corresponding author Department of Physics, Loyola College, Chennai, Tamilnadu- 600034, India.

Geoelectrical resistivity data is used for estimating the subsurface features of earth. It is very difficult to estimate the depth and true resistivity analytically, therefore many mathematical models approximates the result. The approximation relies on many parameters as the heterogenous model of earth is difficult to map. Conventional interpretation algorithm mostly uses the forward modelling technique which is limited for different lithologies. Here we presented ResinvANFIS v1.0 software platform to invert any type (A, Q, K, H or any mixed data types) of resistivity data having AB/2 and apparent resistivity data as input. This kind of generalised platform has not been done elsewhere to invert data directly using soft computing approach.

Preventable factors such as infectious diseases (pneumonia, diarrhea, and malaria), malnutrition and neonatal complications are still the leading cause of child mortality worldwide 1 In 2013, it is estimated that 6.3 million babies born worldwide died before the age of 5, and approximately 9.2% of these deaths were due to diarrheal diseases 23 in simple, accessible ways, and effective treatment can reduce diarrhea-related mortality and make hospital admissions unnecessary, and the role of mothers is the most important 4. Since the presentation of Oral Rehydration Therapy (ORT) in 1979, mortality has reduced. Diarrhea has had a steady downward trend 5. If mothers who have children under 5 years of age, used correctly ORS, they could easily resolve the problem of dehydration in acute diarrhea 6. Mothers didn’t use correctly ORS because of their Low literacy and lack of knowledge and wrong attitude about ORT7. Some health care workers provide mothers’ required equipments, regardless of their educational needs, and mothers may not use ORS. In this study, health workers identified mothers' educational needs and subsequently they trained them about using ORS at home in acute diarrhea in children under 5 years of age.

Plants have played a significant role in maintaining human health and improving the quality of human life. Therefore, this present study seeks to evaluate the role of its alkaloid fraction in the hypothalamic-pituitary-testicular axis after dichlorvos poisoning in mice. A total of 25 male mice, weighing approximately 20-30 g, were randomly assigned into 5 groups of 5 mice each (Groups A, B, C, D and E). Mice in groups A served as control and received normal saline while groups B, C and E. received 5 mg/kg of dichlorvos daily for 14 days. Mice in group D received 200mg/ kg of Alkaloid extract of Mimosa pudica (AEMM) for 14 days. At the end of the experiment, all animals were sacrificed and Hypothalamus, Pituittary and Testes were excised for histological process. Sperm from cauda epididymidal duct on one side was collected and used for spermatological studies and data were expressed as mean± SEM. Significant difference was set at p<0.05. Results showed significance difference (p<0.05) in sperm motility, sperm life death ratio groups when compared with their controls and no significance difference in sperm volume when compared with control. Histological studies reveal distortion in hypothalamuss, pituitary and testes in dichlorvos administration group compared with control rats while mimosa showed a ameliorative effect when co-administered with dichlorvos. In conclusion, the alkaloids from Mimosa (AEM) leaves enhanced the released of gonadotropins by the cordial action of the hypothalamus-pituitary axis for the reversed of Dichlorvos effect.

The Genetic Multiplicity- Multiple Endocrine Neoplasia type I

Multiple endocrine neoplasia type 1 (MEN1) is a syndrome emerging from characteristic mutations of  MEN1 gene with concurrently enunciated  multiple endocrine and tumours and associated non-endocrine neoplasm. Previously designated as Werner’s syndrome, MEN1 syndrome denominates genomic mutation within  chromosome 11q13 or a  tumour suppressor  gene with a distinctive protein product nomenclated as “menin”. MEN1 syndrome demonstrates an autosomal dominant pattern of disease inheritance where genomic mutations delineate  a comprehensive (100%) disease penetrance. MEN1 gene was initially identified in 1997 upon chromosome 11q13. Although twelve genetic mutations were primarily identified, currently beyond eighteen hundred genomic mutations are scripted12. MEN1 syndrome is comprised of diverse combination of twenty or more endocrine and non-endocrine tumours exemplifying a classic triad of pituitary, parathyroid  and pancreatic  neoplasm. Diverse non endocrine tumours enunciated with MEN1 syndrome are denominated with meningioma, ependymoma or angiofibroma12. Endocrine tumours are discerned on account of excessive hormonal secretion engendered from various neoplasm or on account of neoplastic evolution. Approximately 10% instances can occur due to  a de-novo genomic variant. Offspring of an individual with MEN1 syndrome quantifies a 50% possibility of inheriting the genomic variant. Cogent prenatal diagnosis can be determined in instances where  specific genomic variant of a particular family is known. Physical, psychological and social restrictions are prevalent with MEN1 syndrome. Heterozygotes with MEN1 genetic variant are denominated as carriers and manifest a two- fold possible mortality12.

Malaria and typhoid fever are two endemic infectious diseases in developing tropical countries including Burkina Faso. There are two distinct infectious diseases with many similar clinical signs. In each sanitary area, it is important to describe the "typhomalaria" epidemiology to elaborate adequate diagnosis algorithm and efficient treatment protocol. A cross-sectional study was carried out from July to October 2014 in the lab department of University Hospital Souro SANOU, Bobo-Dioulasso. All microscopy positive malaria during the study period was included. Serodiagnosis of Widal and Felix was performed systematically in all Plasmodium spmalaria cases. Titers of antibodies anti-agglutinin O equal or higher than 1/400 and/or 1/800 for anti-agglutinin H antibodies were considered positive for Salmonella sp. A total of 283 malaria cases were included in this study, majority falciparum malaria. In this malaria cases, 91 patients were seropositive for Salmonella sp. "Typhomalaria" co-infection prevalence was 34.3% (CI 95% (28.8%; 40.1%)). The patient with the normal hemoglobin rate had the highest prevalence of co-infection (46.7% versus 30.9; p=0.02). Malaria and typhoid fever co-infection was high (approximately 1/3 of malaria cases) in University hospital of Bobo-Dioulasso. This study revealed the need to explore typhoid fever in malaria confirmed cases, especially in persistent fevers and non-anemic situation despite adapting antimalarial treatment.

Trichoderma reeseiβ-glucosidase (Bgl1) is one of four enzymes demonstrated to act synergistically to degrade cellulose both in vitro and in vivo. Our work attempted to better understand the substrate specificity and potential biotechnological applications of Bgl1. T. reesei Bgl1H cleaves over 80% of the β-(1-4) and β-(1-3) linkages in β-glucan and 14% of the β-(1-4) linkages in amorphous cellulose, significantly more than any tested bacterial β-glucosidase. Bgl1H cleaves 50% of the β-(1-4) linkages in xyloglucan when supplemented with cellulase and α-xyloside. Approximately 20% conversion to glucose was obtained from insoluble β-(1,3)-linked curdlan using only Bgl1H; addition of a curdlanase resulted in conversion of approximately 70% of the curdlan to glucose. Bgl1H also produces xylose from xylooligosaccharides and debranched xylans. For both glucans and xylans, the relative rates of hydrolysis increase with increasing polysaccharide chain lengths. Bgl1H is able to partially degrade β-glucan in a variety of grain components; addition of endo-acting enzymes improved the enzyme’s performance on these grain components. The ability of this enzyme to produce monosaccharides from undigestible polysaccharides suggest it may have potential in improving utilization of carbohydrates in animal feed, fermentations, and other biotechnological applications.

Physical activity (PA) decreases in late adolescence and young adulthood when this age cohort enters the workforce with many being employed in the foodservice industry. Daily energy expenditure can be divided between occupational physical activity (OPA) and leisure-time physical activity (LTPA). Although LTPA is known to be associated with positive health benefits, a limited number of studies have investigated the influence of OPA on LTPA in young restaurant servers. This study measured via accelerometry, OPA and LTPA for a 7-day period from a sample of young adult servers (n = 7, 23-29 years old) from two restaurants. Resting metabolic rate was measured via indirect calorimetry and inputted into the AMP 331 accelerometer for energy expenditure calculations. Energy expenditure patterns were compared to age- and sex-specific normative data, occupational classifications, and the Canadian PA Guidelines to Healthy Active Living (CPAG). Energy expenditure results and step count values were higher for working versus non-working days and working versus non-working periods. Daily, working energy expenditure was approximately equal to normative data, while non-working daily energy expenditure was lower. The working period energy expenditure placed this population in the ‘exceptionally active’ OPA classification. Minimum PA levels, based on CPAG were met each day, however 10,000-steps-per-day were only achieved on working days. None of the participants logged LTPA and therefore 100% of their PA came from OPA. More research is needed over a longer duration and at different times in the year to identify the effect OPA has on LTPA in this population.

Allele Based Inference on Evolution and Extinction; A Genetic Drift Approach

Oluwafemi Oyamakin S.Corresponding author Department of Statistics, University of Ibadan, Nigeria

In other to present a series of stochastic models from population dynamics capable of describing rudimentary aspects of genetic evolution, we studied two-allele Wright–Fisher and the Moran models for evolution of the relative frequencies of two alleles at a diploid locus under random genetic drift in a population of fixed size “simplest form, selection, and random mutation”. Principal results were presented in qualitative terms, illustrated by Monte Carlo simulations from R and http://www.radford.edu/~rsheehy/Gen_flash/popgen. Moran and the Wright-Fisher Models exhibited the same fixation probabilities, only that the Moran model runs twice as fast as the Wright-Fisher Model. A clue that can help us to understand this result is provided by the variance in reproductive success in the two models. Genetic changes due to drift were neither directional nor predictable in any deterministic way. Nonetheless, genetic drift led to evolutionary change in the absence of mutation (P=0.5), natural selection or gene flow. In general, alleles drift to fixation is significantly faster in smaller populations. Probability of fixation of an allele A was approximately equivalent to the initial frequency of that allele. With the inclusion of selection in our model, probability of fixation of a favoured allele due to natural selection increased with increase in fitness advantage and population size. The time taken to reach fixation is much slower, in case of no selective advantage, than a fixation under mutation with selective advantage.

Breast cancer has high incidence in women from both developed and developing countries. Approximately 2 million women are diagnosed with breast cancer in 2018. In Asia, unfortunately Pakistan leads the highest number of breast cancer patients. Various treatment strategies are present but they are not well developed. There is a great need to develop effective methods for early detection and treatment of the disease. For cancer treatment chemotherapeutic interventions have always been a method of choice. One of the mechanisms involved in cancerous cell proliferation is Mevalonate (MVA) pathway. It is hypothesized that arresting MVA pathway leads to cell death hence cancer cell growth is suppressed. Various inhibitors of MVA pathway have been studied that can suppress cell proliferation. Nitrogen containing bisphosphonates are MVA pathway inhibitor and clinically used for treatment of bone diseases. Their anticancer efficacy is also reported. Current study focuses on alendronate, a nitrogen containing bisphosphonate to examine their anticancer effect on breast cancer cell line. Results of this study may help in addition of new anticancer drug for breast cancer.

Recurrent pregnancy loss is an important reproductive issue with a heterogeneous etiology where two or more consecutive abortions occur before 20 weeks of gestation. Approximately 15% of all clinically recognized pregnancies result in miscarriage with an incidence of 1 in 300 cases. Couples, who experience repeated pregnancy loss before three months of gestation, mostly have fetuses with chromosomal aneuploids. A non-consanguineous couple with a married life of 4 years was referred to the Institute with a clinical history of three first trimester abortions. Karyotype analysis revealed a balanced autosomal translocation between chromosomes 4 and 6 with 46, XX, t (4;6)(q35; q22) karyotype in the female and normal 46, XY in the male partner. Therefore, the siblings and the couple were suggested for extended genetic counseling. Interestingly, similar translocation was seen in her father and three sisters, whereas her mother and elder sister showed a normal chromosomal constitution, indicating the paternal inheritance.

Cesarean sections (CS) are one of the most commonly performed surgical procedures worldwide. There is great variability in the percentage of cesarean sections between countries, varying from 3% to 42.9%5. In the US, approximately 32% of deliveries occur through a cesarean section. Overall, a drastic increase in cesarean section rate has been reported reaching its highest level at the present time. In Brazil, considering the types of births by live births from 2006 to 2016, the national percentage of cesarean section was 52.37%. The variability in this percentage can still be perceived within Brazilian territory. The highest cesarean rate occurred in the Southern region, representing 58.33% of births, while the lowest rate occurred in the Northern region, with 41.79%. It is possible to see the steady increase in the percentage of CS over time, from 45.01% in 2006 to 55.39% in 2016.

The potential of Nigerian indigenous tree leaves as vegetable source, pharmaceuticals and other therapeutic materials have been reported. However, Silk cotton (Ceiba pentandra) leaf is still underutilised as vegetable in parts of Nigeria where it exists despite its potential great health benefits. The aim of the study was to assess the micronutrient and phytochemical potential contribution to nutrient intake of its consumers, and acceptability of its cooked soup and sauce ‘as consumed’. Fresh young shoots and leaves of Ceiba pentandra were harvested from Ihitte/Uboma in Imo State, Nigeria. Composite sample of the leaf was prepared and divided into four portions. One portion was labelled as raw sample, and others blanched, cooked to soup and sauce. The four samples were analysed for proximate, minerals, vitamins and phytochemical composition using standard methods of AOAC. Sensory evaluation of soup and sauce was carried out using 9-point hedonic scale with 30 untrained panelists. Data were analysed using ANOVA at p<0.05 Raw Ceiba pentandraleaf contained 80.9g moisture, 3.9g protein, 0.8g fat, 15.3g carbohydrate, 68.40 kcal gross energy, 183.40mg potassium, 119.38mg calcium, 112.99mg phosphorus, and 3.46mg iron/100g sample. The leaf was rich in phytochemicals such as saponins, flavonoid and alkaloids. Raw sample was highest in water-soluble vitamins while the sauce was highest in β-carotene (339.72µg/100g). Cooking the leaf to soup and sauce significantly increased the mineral content of the products (P<0.05) with reduction in water-soluble vitamins and phytochemicals (P<0.05). The sensory attributes of the soup and sauce were generally acceptable to the panelists, with the sauce being more acceptable. The leaf and its products were rich in essential minerals, vitamins and phytochemicals. The sauce retained more nutrients compared to other samples. Inclusion of this underutilised vegetable in diets will reduce micronutrient malnutrition, promote dietary diversity, good health and wellness.

Muschietti LilianaCorresponding author Universidad de Buenos Aires, Cátedra de Farmacognosia, Facultad de Farmacia y Bioquímica (UBA), IQUIMEFA (UBA-CONICET), Buenos Aires, Argentina

In recent years, the consumption of dietary supplements (DS) has increased worldwide. In Argentina, approximately 14 million DS units were sold between 2015 and 2017. The adulteration of DS with active pharmaceutical ingredients or their analogues has been reported. This represents an alarming emerging risk to public health. The aim of this work was to detect the possible adulteration of a DS marketed in Argentina for the treatment of erectile dysfunction. Initially, thin layer chromatography analysis of the DS capsules content suggested the presence of a major compound. For the isolation and purification of this compound, an easy method consisted of a liquid-liquid extraction (water/CH2Cl2) followed by re-crystallisation from ethanol, is reported. Spectroscopic techniques such as mono- and bidimensional nuclear magnetic resonance, Fourier transform infrared spectroscopy and mass spectrometry allowed its identification as tadalafil. A rapid and reliable method was developed for the quantification of tadalafil in this DS by high performance liquid chromatography-mass spectrometry (HPLC-MS/MS). The mean content of tadalafil per capsule was 21.2 mg which represents a slightly higher value than that found in approved products in Argentina (5 or 20 mg per tablet). In addition, an undeclared alga was identified in the DS by microscopic techniques.

Sedky KarimCorresponding author Professor of Psychiatry and Medical Student Clerkship Director, CMSRU, Camden, NJ.

Study Objectives: Narcolepsy diagnosis has been associated with a long lag time between the onset of the disorder and the diagnosis itself among patients with the disorder. This article reviews the childhood epidemiology of idiopathic narcolepsy, including its prevalence, subtypes, and disease progression. Methods: A literature review was conducted to include both published and unpublished data on pediatric narcolepsy. All English language articles were included through April, 2015. Results: Time from symptom onset to diagnosis for children is approximately three years. The prevalence of cataplexy appears to be lower in children compared to adults, suggesting a later onset of cataplexy. The presence of cataplexy, however, was unrelated to demographic factors and laboratory findings. Conclusion: There is a substantial lag-time between initial symptom presentation and diagnosis in children with narcolepsy. A less quintessential presentation of narcolepsy might occur in children relative to adults, making diagnosis more challenging. Continued improvements in narcolepsy education for both pediatricians and parents might facilitate earlier identification and diagnosis of the disease, thus leading to improved outcome.

Estimates of the genetic diversity of Large Japanese field mouse Apodemusspeciosus populations and identification of their plant food resources were conducted in an industrial green space, where were constructed on reclaimed land and belonged to the Aichi Refinery of Idemitsu Kosan Co., Ltd., in Aichi Prefecture, Japan. A total of six mitochondrial D-loop haplotypes were identified in 50 mice. Habitat condition with the highest number of captured individuals had abundant broad-leaved trees and understory vegetation. A minimum spanning network, which did not form a ring-shaped network, revealed that the hereditary population structure was weak. The low genetic diversity observed in the study area was thus attributed to isolation from other populations once the population in the study area by sea and road, which is more than 30 m wide. In order to identify which plant food resources were utilized by mice captured inside the industrial green space, partial chloroplast rbcL sequences were amplified by PCR from DNA extracted from 43 feces samples. Calculations of sample completeness curve revealed that 25 of the taxa identified in this study comprised approximately 90% of the food plant resources in the study area. Of the 21 plant families identified from the obtained rbcL sequences, members of the Rosaceae (28.0%), Fagaceae (17.2%), Lauraceae (14.2%) and Oleaceae (7.7%) were dominant. To ensure the continued survival of A. speciosuspopulation in this industrial green space would be to preferentially conserve plant species that are used as food resources by this species.

Profiling Flight Performance of Young Racing Pigeons (Columba Livia) in Training

Feb 2018 DOI 10.14302/issn.2575-1212.jvhc-17-1796
Scullion F.T.Corresponding author Veterinary Services, N. Ireland

Two groups of young pigeons were trained and flight parameters profiled over a flight path of approximately 90 km and a number of measures were developed to analyse their flight performances. An aerodynamic model of avian flight was fitted to the data to assess its value in predicting flight performances. Both groups, although trained and flown independent of each other, had very similar profiles through time. Race speeds home peaked between weeks 5 - 8 of training and averaged 15.0 (2.0) m/s for Group 1 and 15.6 (2.7) m/s for Group 2. Flight performance in early stages of training in this study seemed to be affected by previous health conditions but once training progressed beyond 5 weeks, young pigeons appeared to fly at a constant preferred speed.

Feb 2018
C Verster JorisCorresponding author Division of Pharmacology, Utrecht University, Utrecht, The Netherlands.

Introduction and aims Previous research has focused primarily on the severity of the alcohol hangover. Much less is known about the duration of the alcohol hangover. The objective of this analysis was to examine the average duration of the alcohol hangover. Design and Methods N=811 Dutch students, aged 18-30 years old, completed a survey on alcohol consumption and their latest alcohol hangover. Overall hangover severity was reported for every two hours after waking up (starting 4am until midnight). Hangover duration was calculated from the moment of stopping alcohol consumption until the first time hangover severity scores reached zero. Results During the drinking session that resulted in their latest hangover they consumed a mean (SD) of 5.9 (6.2) alcoholic drinks, followed by 6.5 (2.0) hours of sleep. The start of the alcohol hangover was not assessed, as it can be assumed that BAC approached zero while participants were sleeping. From the moment of stopping alcohol consumption, the average duration of the alcohol hangover was 18.4 (3.8) hours. For the majority of drinkers, hangover duration ranged from 14 to 23 hours. Alternatively, the hangover lasts approximately 12 hours from the time of waking up. Hangover duration correlated significantly with hangover severity and total sleep time, but no significant association was found with the number of alcoholic drinks that were consumed. Discussion and Conclusions The duration of the alcohol hangover ranged from 14 to 23 hours, with an average of 18.4 hours after stopping drinking, or alternatively, about 12 hours after waking up.

Background Hypertension is one of the most prevalent risk factors for myocardial infarction, strokes, congestive cardiac failure and chronic kidney disease (CKD)and its prevalence is significantly higher inthe elderly population. Objectives To assess the demography, various presentations and the prevalence of risk factors among elderly hypertensive patients followed up in a tertiary care hospital in Sri Lanka. Materials and Methods This was a cross sectional descriptive study involving 250 patients whoseage was 60 years or above onantihypertensives for at least 6 months. Results Approximately 65.2% of the study population was female. The mean age was 70.17.Dizziness and chest pain were the most prevalent symptoms.The mean age at first detection was 58.17 years.Mean SBP and DBP were 128.5mmHg and 81.14mmHg respectively. The prevalence of alcohol consumption and smoking among men were 70.1% and 72.4% respectively. Approximately 54.7% were either overweight or obese.Approximately 81.6% females and 41.4% males had a waist circumference ofmore than therisk level with p-value<0.05. Approximately 36% had diabetes mellitus and 27.6% of the patients had at least one parent and 36.8% had at least one sibling diagnosed with hypertension. Approximately 61.3% of the patients hadadequate levels of physical activity while 31.8% had IHD,11.5% had stroke and 3.8% had CKD. Conclusion Dizziness and chest pain were the most disturbing symptoms while abdominal obesity among females,and alcohol consumption and smoking among males were the major risk factors in elderly hypertensive patients

Hypovitaminosis D is common among older people and treatment with vitamin D is associated with reduced risk of falls and fractures. This paper provides a cost analysis of assessing the vitamin D status of and providing the pharmaceuticals for elderly citizens in Kalmar County, Sweden (population approximately 230,000). Four hypothetical interventions were analyzed: (a) systematic vitamin D/calcium supplementation to all elderly (≥75 years), (b) assessment of vitamin D status in elderly and supplementation to those with insufficient levels, (c) systematic vitamin D/calcium supplementation to all nursing-home residents, and (d) assessment of vitamin D status in nursing-home residents and supplementation to those with insufficient levels. The calculations were based on an estimated reduction in overall costs due to the assessed number of hip fractures after vitamin D/calcium supplementation. The annual net economic benefit of vitamin D/calcium supplementation was estimated at (a) €304,000, (b) €860,000, (c) €755,000, and (d) €740,000. The provision of systematic vitamin D supplementation to nursing-home residents would provide a substantial net economic benefit to society and assessment of the vitamin D status before starting supplementation does not seem to be necessary. Although assessment of all elderly citizens would be more comprehensive, the true proportion with insufficient vitamin D levels in the general population is uncertain and to reaching consensus on the most advantageous daily vitamin D intake, vitamin D blood levels are necessary. Also, systematic supplementation to all elderly would result in other outcomes that could be worth the cost, but that remains to be evaluated.

Adipose tissue inflammation is associated with obesity comorbidities. Reducing such inflammation may ameliorate these comorbidities. n-3 fatty acids have been reported to have anti-inflammatory properties in obesity, which may modulate this inflammatory state. In the current study a 1 gram per day oral supplement of the n-3 fatty acid docosahexaenoic acid (DHA) was administered for 12 weeks to 10 grade 12 obese postmenopausal women and markers of adipose tissue and systemic inflammation measured and compared before and after supplementation. DHA administration resulted in approximately a doubling of plasma and red cell phospholipid and adipose tissue DHA content but no change in systemic markers of inflammation, such as circulating C-reactive protein (CRP) or interleukins (IL) 6, 8 and 10 (IL-6, IL-8, IL-10). DHA supplementation did not alter the adipose tissue marker of inflammation crown-like structure density nor did it affect any gene expression pathways, including anti-inflammatory, hypoxic and lipid metabolism pathways. The obese postmenopausal women studied were otherwise healthy, which leads us to suggest that in such women DHA supplementation is not an effective means for reducing adipose tissue or systemic inflammation. Further testing is warranted to determine if n-3 fatty acids may ameliorate inflammation in other, perhaps less healthy, populations of obese individuals.

Brain tumors occur when abnormal cells form within the brain.There are two main types of tumors: malignant and benign tumors. Then, tumors can be divided into primary that start within the brain, and secondary tumors that have spread from somewhere else, known as brain metastasis tumors. Secondary brain tumors occur in approximately 15 % of cancer patients with about half of metastases coming from lung cancer. Primary brain tumors occur in around 250,000 people a year globally, making up less than 2% of whole body tumors. According to American Brain Tumor Association the most common types of primary tumors are gliomas, representing 74,6 % of all malignant tumors and meningiomas ( 36,6% ) while more affected region is frontal lobe, about 22 % . Particularly, prefrontal cortex ( PFC ), the anterior part of the frontal lobe that is highly developed in humans plays a role in the regulation of personality, emotional, and behavioral functioning, leading to serious cognitive impairments 1. These are the psychological signs of frontal lobe tumors, in addition to other functions such as the expressive language of Broca's area or those relating to voluntary movement, linked to frontal cortical motor areas. It relates to the so-called higher nervous functions, concerning the life of relationship and communication. The PFC physiology explains the psychological mechanisms of its associated functions: connections with the limbic cortex, thalamus, hypothalamus, basal ganglia and other subcortical areas.The regions of the PFC at the base of the psychophysiological mechanisms involved are basically the dorso-lateral, the ventro-medial, the orbito-frontal establishing contacts primarily with limbic structures, such as the cingulate gyrus, hippocampus, amygdala.

Hypertension is a major modifiable risk factor for cardiovascular disease, responsible for approximately 31% of global mortality. The aim of this study was to examine the hypertensive responses and determine the peak rate pressure product, calculated by multiplying systolic blood pressure and heart rate, during isometric handgrip exercise. Rate pressure product is a surrogate measure of myocardial oxygen consumption. Hypertensive responses utilising rate pressure product during isometric handgrip exercise have not previously been reported. A randomized trial was conducted with 60 normotensive and 60 pre-hypertensive participants who attended once for an acute session of isometric handgrip exercise. Participants were randomized into groups exercising at 5%, 10% or 30% of their maximum voluntary contraction. Training was conducted using 4x2min isometric handgrip exercises each separated by a 3min rest period. There were no significant differences between peak systolic and diastolic blood pressure, mean arterial pressure, heart rate and rate pressure product across the four bouts of isometric handgrip exercise in all groups, all p>.05. Peak increases in rate pressure product were significantly higher than baseline at all intensities assessed; all normotensive groups p<.02, all pre-hypertensive groups p≤.001. Increases were relative to baseline blood pressure status and intensity of isometric handgrip exercise, with no significant differences between normotensive and pre-hypertensive groups. Rate pressure product responses to isometric handgrip exercise indicate that it may be a safe alternative for people unable to perform recommended levels of aerobic exercise for blood pressure management.

YA Dei-AdomakohCorresponding author Departments of Haematology

Background: The diagnosis and treatment outcomes of Non- Hodgkin Lymphoma’s (NHL) in resource poor countries in the absence of routine molecular studies and immunohistochemistry is challenging. Methods: A retrospective review of case folders of NHL patients aged13 years and above. Information obtained from the case folders included age, sex, histological subtype, subtypes using the Working Formulation and WHO classifications. Treatment given and follow up information were also evaluated. Results: A total of 279 cases of NHL were identified within the study period. The mean age of the patients was 48.8 ± 17.0 years. The male to female ratio was approximately 1.5:1. The majority of cases seen (53%) were diffuse large B- cell lymphoma. Chronic lymphocytic leukaemia/ small lymphocytic lymphoma (22.2%) was the next most common subtype. Other sub types seen, in order of frequency, included diffuse mixed cell lymphoma (6.4%), gastric lymphomas (3.9%), mediastinal B- cell lymphoma (2.9%), Burkitt’s lymphoma (1.8%), splenic marginal zone B-cell lymphoma (1.1%), lymphoblastic lymphoma (1.1%), mucosa- associated lymphoid tissue (MALT) type B- cell lymphoma (0.7%) and follicular lymphoma (0.7%). Conclusion: This study provides an overview of the distribution of NHL subtypes and their outcomes in a resource constrained setting. Immunohistochemistry, cytogenetics and specific molecular studies which are important in characterization of NHLs, should be made affordable and accessible in low income countries.

Objectives: This pilot study explored post-traumatic stress symptoms (PTSS) and moderate to severe psychological distress in a small sample of urban community-living adolescents seeking asylum in Australia. The study also examined the relationships between post-traumatic stress symptoms (PTSS) and psychological distress and school and family support and connectedness. Method: A cross-sectional survey examined PTSS (Abbreviated PTSD Checklist), psychological distress (Kessler-5) and school connectedness (California Healthy Kids Survey)53 in 27 adolescents seeking asylum (ages 12-17, mean 15.4) attending two independent secondary schools in Perth, the capital city of Western Australia. Results: In the sample, 63.0% (n=17, 1 missing) of adolescents exceeded the PTSS threshold (i.e. screened positive for Post-traumatic Stress Disorder) and 66.7% (n=18) exceeded the Kessler -5 threshold indicating moderate to severe psychological distress. Overall, 51.9 % (n=14, 1 missing) of adolescents screened above both thresholds suggesting co-occurrence of PTSD and moderate to severe psychological distress. Boys (x̄=15.0, SD=2.9) experienced higher psychological distress scores than girls (x̄=12.1, SD=4.5; p=0.071). Higher perceived support by an adult in school (r=0.13), and at home (r=0.28) were weakly associated with lower PTSS. Less time in Australia was weak-moderately associated with higher psychological distress (r=0.35). Weak associations between higher psychological distress and age (r=0.17) and those who felt more supported by an adult at home (r=0.17) were detected. Conclusion: Approximately two thirds of this group of community-living adolescents who were seeking asylum experienced post- traumatic stress symptoms or psychological distress; and more than one half experienced both. These pilot research findings suggest that adolescents who are seeking asylum and living in the Australian community are at risk of experiencing PTSD and moderate to severe psychological distress; research incorporating larger samples and longitudinal measurement is required. Screening, clinical assessment and examination of the immediate and long term impact, as well as implementation and evaluation of evidence-based mental health interventions, within these populations is also recommended.

Purpose: The aim of the study was to analyze the spatial relationship between the sinus floor and the alveolar bone of maxillary premolars and molars in order to assess the amount of basal bone available for immediate extraction placement of endosseous implants. Materials and Methods: All the cone-beam computerized tomographic (CBCT) scans taken over a three-year period at four centers were identified. The subsinus bone height (SBH) was evaluated by measuring the distance between the sinus floor and the first and second premolar root apexes. The interradicular septum bone height (ISBH) of all the first and second molars was also measured, and the presence or absence of sinus-floor invagination between the molar roots was recorded. Results: Five hundred twenty-six (526) CBCT scans of fully or partially dentate maxillary arches were examined. The root apex was inside the sinus of 1.8% of all the first premolars. It approximated the sinus floor of 5.3% of them, and the distance between the two points was between 1 and 3mm of 20%, between 3 and 7mm for 34.1%, and more than 7mm for 34.1%. For the second premolars, the findings were 13.5% (inside the sinus), 10.5% (touching the sinus), 32.8% (1-3mm of distance) 28% (3-7 mm), and 15.2% (more than 7mm). Root invagination was noted in 50.2% of the first molars and 43.1% of the second molars, with the ISBHs ranging from 13.4% to 56.9%. Conclusion: Radiological evaluation is essential to determining whether implants should be placed immediately after extraction of maxillary premolars and molars.

Objectives: Adenocarcinoma of prostate is an internationally important health problem of the man, particularly in developed countries. The aim of this exploratory study was to evaluate whether significantchanges in the prostatic tissue levels of calcium (Ca), potassium (K), and magnesium (Mg) as an androgen dependent chemical element, and bromine (Br), manganese (Mn), and sodium (Na), as androgen independent elements, exist in the malignantly transformed prostate. Methodology: Prostatic tissue levels of Br, Ca, K, Mg, Mn, and Na contents were prospectively evaluated in 10 patients with adenocarcinoma and 37 healthy male inhabitants. Measurements were performed using non-destructive instrumental neutron activation analysis with high resolution spectrometry of short-lived radionuclides. Tissue samples were divided into two portions. One was used for morphological study while the other was intended for chemical element analysis. The reliability of difference in the results between normal and cancerous prostate tissues was evaluated by Student’s t-test. Key Results: Mean values ± standard error of means (M±SΕΜ) for mass fraction (mg/kg on dry mass basis) of chemical element in the normal tissue were:Br32.9±3.6, Ca 2280±178, K 11211±414, Mg 1118±76, Mn 1.24±0.07, and Na 11100±408, respectively. The contents of Br and Mn were significantly higher (approximately 4 and 6 times, respectively) while those of Ca and Mg (nearly 3 times) and K and Na (20% and 30%, respectively) were significantly lower in cancerous tissues than in normal tissues. Major Conclusions: In adenocarcinoma transformed prostate tissue the chemical element metabolism is significantly disturbed.

Phytochemicals (PHT) are a large group of biologically active plant chemicals that may have positive effects on human health such as immune system stimulation, down regulation of inflammatory responses, radical scavenging activities, cell repair function, and antibacterial and antiviral activity. In this proof of principle 6 months study, the effects of supplementing a PHT mix, Phyto V7, to HIV-1 seropositive individuals and AIDS patients were examined. Individuals with CD4+ T-cells below 350 counts/mm3were assigned to one of the following treatments: CG1 - no treatment, CG2 - only highly active antiretroviral treatment (HAART), TG1 - only Phyto V7, and TG2- both Phyto V7 and HAART. After 3 months of treatment there were approximately (-)1%, 1%, 2% and 4% increase in the mean weight of the CG1, CG2, TG1 and TG2 groups, respectively. The tendency for the body mass index (BMI) was similar. The CD4+ counts increased by 13%, 39%, 53% and 35%, respectively. Similar trends were noted after 6 months with 2%, 79%, 53% and 69% increases in the CD4+ counts, respectively. There was a significant reduction in viremia only in groups receiving HAART. Overall better results were obtained in the group of patients receiving both HAART and Phyto V7, in which the mean weight increased by 5.7% and the CD4+ T-cell counts increased by 69% after 6 months. This study indicates that providing Phyto V7 to HIV-1 seropositive individuals and AIDS patients, receiving or not receiving HAART, improves their physical wellbeing and CD4+ counts, enabling them to cope better with the viral infection.

This study sought to assess the impact of part-time employment on the nutritional status of women in rural Nepal. We used longitudinal data from a prospective cohort of women in the Sarlahi District of southeastern Nepal to assess whether part-time employment was associated with a change in mid-upper-arm circumference (MUAC) between baseline and five-years. The women enrolled in the study (n =715) had applied for part-time employment distributing weekly vitamin A supplements to married women of childbearing age. Over the five-years of follow-up, women received 900 Nepalese rupees ($15 USD) per month, for approximately five hours of work per week. The women who were hired (n =324) were younger and better educated than those who were not hired (n =391), but were otherwise similar. After baseline adjustments, change in MUAC (in cm) (β = 0.08; 95 % CI: -0.20, 0.36) was not associated with employment.  Also, changes in MUAC over time were inversely related to baseline MUAC, with better nourished women gaining less (MUAC of 23 - 24.99: β = -0.83; 95% Confidence Interval CI: -1.18, -0.48; MUAC of ≥ 25: β = -0.99; 95% CI: -0.99, -0.54) compared to thin women (MUAC <21). In this sample, women employed part-time did not have improved nutritional status as compared to their unemployed counterparts. Future research should explore the impact of women’s employment on the nutritional status of other members of the household, particularly children, and among women employed full-time.
