Air pollution is a global public health threat. Evidence suggests that increased air pollution leads to increased cardiovascular morbidity and mortality. The aim of this review was to systematically review and synthesize scientific evidence to understand the effect of performing outdoor physical activity (PA) in a polluted environment on cardiovascular outcomes. This review was developed and reported in accordance with the PRISMA guidelines. Electronic searches in Embase, Web of Science, and PubMed were undertaken through March 2021 initially, and later updated through to 31st January 2022, for observational studies published in peer-reviewed journals that report cardiovascular mortality or morbidity due to outdoor PA in air polluted environment. These searches yielded 10,840 citations. Two reviewers independently reviewed each citation for its eligibility. Seven studies were found to be eligible. Of these, five were cohort studies and two were cross-sectional studies. Pollutants measured in the selected studies were Particulate Matter (PM)—PM10, PM2.5, nitrogen oxides (NO_x), and ozone (O₃). The most common study outcome was myocardial infarction, followed by cardiovascular mortality, hypertension and heart rate variability. Six studies emphasized that the PA has beneficial effects on cardiovascular outcomes, though air pollutants attenuate this effect to an extent. Two studies showed that walking, even in the polluted environment, significantly reduced the heart rate and heart rate variability indices. The beneficial effects of outdoor PA outweigh the harmful effects of air pollution on cardiovascular health, though the benefits reduce to an extent when PA is carried out in a polluted environment. Because a limited number of studies (n = 7) were eligible for inclusion, the review further emphasizes the critical need for more primary studies that differentiate between outdoor and indoor PA and its effect on cardiovascular health.

Maternal undernutrition can lead to protein-energy malnutrition, micronutrient deficiencies, or anemia during pregnancy or after birth. It remains a major problem, despite evidence-based maternal-nutrition interventions happening on ground. We conducted a scoping review to understand different strategies and delivery mechanisms to improve maternal nutrition, as well as how interventions have improved coverage and uptake of services. An electronic search was conducted in PubMed and Google Scholar for published studies reporting on the effectiveness of maternal-nutrition interventions in terms of access or coverage, health outcomes, compliance, and barriers to intervention utilization. The search was limited to studies published within ten years before the initial search date, 8 November 2019; later, it was updated to 17 February 2021. Of 31 studies identified following screening and data extraction, 22 studies were included for narrative synthesis. Twelve studies were reported from India and eleven from Bangladesh, three from Nepal, two from both Pakistan and Thailand (Myanmar), and one from Indonesia. Nutrition education and counselling, home visits, directly observed supplement intake, community mobilization, food, and conditional cash transfer by community health workers were found to be effective. There is a need to incorporate diverse strategies, including various health education approaches, supplementation, as well as strengthening of community participation and the response of the health system in order to achieve impactful maternal nutrition programs.

Introduction/background The nationwide lockdown enforced due to the spread of coronavirus disease-2019 had a definite impact on sleep. Objective To observe any changes in the duration, pattern and quality of sleep among pharmacy students due to the lockdown. Methods A google form-based cross-sectional and descriptive study was carried out after approval was obtained from the ethical committee in the month of July 2021 among 310 pharmacy students. The validated form was electronically administered after obtaining the informed consent. All the data pertaining to duration, pattern and quality of sleep before and during the lockdown was collected and analyzed using STATA version 16.0. Results and Discussion Out of 310 participants, the study revealed an increase in the time needed to fall asleep (p value < 0.001) and in the total duration of sleep (p value < 0.001). A delay in the time of sleep in the morning (p value < 0.001) and at night (p value < 0.001) was also one among the many significant results. The incidences of jerky leg movements (p value < 0.001), snoring (p value < 0.001), frequent nightmares (p value < 0.001) and anxiety (p value < 0.001) were also increased as a direct effect of the lockdown. Conclusion The study has confirmed the detrimental impact of the lockdown on sleep among pharmacy students. All attributes of sleep duration and sleep quality have achieved statistical significance signifying the need to develop cognitive behavioral interventions and prevent the worsening of mental health amidst the COVID-19 era.
