Introduction Physical, psychological, and emotional growth are among the changes that define the adolescent stage. As compared to other age groups, adolescents are more vulnerable to sexual and reproductive health issues. Parents can become protective and influencing factors for their children to prevent risky sexual behavior. This study aims to assess adolescent-parent communication on sexual and reproductive health and its associated factors. Methods A descriptive cross-sectional study was conducted among 212 adolescents aged 15–19 in higher secondary schools of Tokha Municipality. A self-administered structured modified questionnaire to assess the communication used the Weighted Topics Measure of Family Sexual Communication (WTM) tool with a simple random sampling technique of data collection. We performed descriptive statistical analysis and chi-square tests to analyze data and assess the association between variables. Data quality was assured through careful questionnaire design, pretesting, and training. Results The study found that about 75.9% of adolescents had communicated on SRH topics with their parents. Only 56.1%, 50.1%, 55.2%, and 50.5% of adolescents communicated about choosing a life partner, menstruation, physical and psychological changes during adolescence, and the physical growth and development of reproductive organs, respectively, while topics like using birth controls, when to start having sex, pregnancy, how to handle sexual pressure from a partner, STI and HIV/AIDs, about condoms, and abortion had never communicated by 61.3%, 86.6%, 69.3%, 85.8%, 72.2%, 78.8%, and 82.5% of adolescents, respectively. Adolescent-parent communication on sexual and reproductive health was significantly associated with the level of knowledge regarding sexual and reproductive health (X2 = 5.809, p = 0.01, df = 1). Similarly, there was a significant association with the perceived parenting style (X2 =3.932, p =0.04, df =1), living arrangements (X2 =6.376, p=0.01, df =1), and adolescent-parent communication. Conclusion It concluded that adolescent-parent communication on SRH issues is not satisfactory. Creating an adolescent-friendly environment at home and conducting awareness programs with the help of the local government of the respective schools would help to increase adolescent-parent communication.

To understand lung damages caused by COVID-19, we deduced two phases lung damage mechanisms. After the lungs are infected with COVID-19, the affected lung tissue swells and surface properties of pulmonary capillaries change, both contributing to an increased flow resistance of the capillaries. The initial damages are mainly fluid leakage in a limited number of involved alveoli. The increased vascular resistance results in retaining more white blood cells (“WBCs”) in pulmonary capillaries. Some of the WBCs may get into interstitial spaces. When more and more WBCs are dynamically retained, the vascular resistance of pulmonary capillaries further rises; and thus the overall vascular resistance of the lungs rises and pulmonary pressure rises. The rise in the pulmonary pressure in turn results in elevated capillary pressures. When pulmonary capillary pressures around the alveoli are sufficiently high, the elevated pressure causes interstitial pressures to change from normally negative values to positive values. The positive pressures cause fluid leakage to the alvoeli and thus degrade lung function. Tissue swelling, and occupation of WBCs in interstitial spaces and occupation of alvoelar spaces by leaked water result in reduced deformable and compressible spaces, and thus causes a further rise of the vascular resistance of the lungs. When the pulmonary pressure has reached a critical point as in the second phase, the blood breaks capillary walls and squeezes through interstitial spaces to reach alveolar spaces, resulting in irreversible lung damages. Among potential influencing factors, the available space in the thorax cage, temperature, and humid are expected to have great impacts. The free space in the thorax cage, lung usable capacity, and other organ usable capacities are the major factors that determine the arrival time of last- phase irreversible damage. The mechanisms imply that the top priority for protecting lungs is maintaining pulmonary micro-circulation and preserving organ functions in the entire disease course while controlling viral reproduction should be stressed in the earliest time possible. The mechanisms also explain how leukecytes are “recruited and migrated” into inflamed tissues by dynamic retention.

Advances in nanotechnology especially in nanofluids comprising of a typical base fluid saturated with nano-size metallic particles with enhanced thermophysical properties is one of the hot topics in industrial as well as engineering applications of applied mathematics. This article explores the impact of Lorentz forces and Maragoni effect on second grade nanofluid forced convective flow. A two phase model is chosen to validate the nanofluid. Series solutions are achieved through HAM after transformation of PDEs into ODEs. The Brownian motion effect, Thermophoresis and the Marangoni effect are the main influencing factors for present flow model. In addition, the influence of pertinent fluid parameters such as Schmidt number, Magnetic number and Prandtl number on the velocity, temperature and concentration profiles is discussed with the help of graphs. With an enhanced Marangoni factor the hydraulic boundary layer thickness shows enhancement.
