Review
This review and meta-analysis aimed to describe the current rugby-7s injury epidemiological literature by examining injury data from both sexes, all levels of play, and their associated risk factors. Studies published up until March 2024 were included. These studies were retrieved from six databases using search terms related to rugby-7s or sevens, tackle, collision, collision sport, injury, athlete, incidence rate, mechanism, and risk factor. Only peer-reviewed original studies using prospective or retrospective cohort designs with a clearly defined rugby-7s sample were considered. Included studies needed to report one injury outcome variable. Non-English and qualitative studies; reviews, conference papers, and abstracts were excluded. Twenty studies were included. The meta-analysis used the DerSimonian-Laird continuous random-effects method to calculate the pooled estimated means and 95% confidence interval. The estimated mean injury incidence rate for men was 108.5/1000 player-hours (95% CI: 85.9-131.0) and 76.1/1000 player-hours (95% CI: 48.7-103.5) for women. The estimated mean severity for men was 33.9 days (95% CI: 20.7-47.0) and 44.2 days (95% CI: 32.1-56.3) for women. Significantly more match injuries occurred in the second half of matches, were acute, located at the lower limb, diagnosed as joint/ligament, and resulted from being tackled. Fatigue, player fitness, and previous injuries were associated with an increased risk of injury. There were no statistically significant differences between women's and men's injury profiles. However, the inherent cultural and gendered factors which divide the two sports should not be ignored. The findings from this review will help pave the way forward beyond the foundational stages of injury prevention research in rugby-7s.

BACKGROUND
Women are known to be disadvantaged compared with men in the early links of the Chain of Survival, receiving fewer bystander interventions. We aimed to describe sex-based disparities in emergency medical service resuscitation quality and processes of care for out-of-hospital cardiac arrest.
METHODS AND RESULTS
We conducted a retrospective analysis of patients who were nontraumatic with out-of-hospital cardiac arrest aged ≥16 years where resuscitation was attempted between March 2019 and June 2023. We investigated 18 routinely captured performance metrics and performed adjusted logistic and quantile regression analyses to assess sex-based differences in these metrics. During the study period, 10 161 patients with out-of-hospital cardiac arrest met the eligibility criteria, of whom 3216 (32%) were women. There were no clinically relevant sex-based differences observed in regard to external cardiac compressions; however, women were 34% less likely to achieve a systolic blood pressure >100 mm Hg on arrival at the hospital (adjusted odds ratio [AOR], 0.66 [95% CI, 0.47-0.92]). Furthermore, women had a longer time to 12-lead ECG acquisition after return of spontaneous circulation (median adjusted difference, 1.00 minute [95% CI, 0.38-1.62]) and 33% reduced odds of being transported to a 24-hour percutaneous coronary intervention-capable facility (AOR, 0.67 [95% CI, 0.49-0.91]). Resuscitation was also terminated sooner for women compared with men (median adjusted difference, -4.82 minutes [95% CI, -6.77 to -2.87]).
CONCLUSIONS
Although external cardiac compression quality did not vary by sex, significant sex-based disparities were seen in emergency medical services processes of care following out-of-hospital cardiac arrest. Further investigation is required to elucidate the underlying causes of these differences and examine their influence on patient outcomes.

BACKGROUND
The association between soy isoflavones intake and cardiometabolic health remains inconclusive. We investigated the associations of urinary biomarkers of isoflavones including daidzein, glycitein, genistein, equol (a gut microbial metabolite of daidzein), and equol-predicting microbial species with cardiometabolic risk markers.
METHODS AND RESULTS
In a 1-year study of 305 Chinese community-dwelling adults aged ≥18 years, urinary isoflavones, fecal microbiota, blood pressure, blood glucose and lipids, and anthropometric data were measured twice, 1 year apart. Brachial-ankle pulse wave velocity was also measured after 1 year. A linear mixed-effects model was used to analyze repeated measurements. Logistic regression was used to calculate the adjusted odds ratio (aOR) and 95% CI for the associations for arterial stiffness. Each 1 μg/g creatinine increase in urinary equol concentrations was associated with 1.47%, 0.96%, and 3.32% decrease in triglycerides, plasma atherogenic index, and metabolic syndrome score, respectively (all <0.05), and 0.61% increase in high-density lipoprotein cholesterol (=0.025). Urinary equol was also associated with lower risk of arterial stiffness (aOR, 0.28 [95% CI, 0.09-0.90]; =0.036). We identified 21 bacterial genera whose relative abundance was positively associated with urinary equol (false discovery rate-corrected <0.05) and constructed a microbial species score to reflect the overall equol-predicting capacity. This score (per 1-point increase) was inversely associated with triglycerides (percentage difference=-1.48%), plasma atherogenic index (percentage difference=-0.85%), and the risk of arterial stiffness (aOR, 0.27 [95% CI, 0.08-0.88]; all <0.05).
CONCLUSIONS
Our findings suggest that urinary equol and equol-predicting microbial species may improve cardiometabolic risk parameters in Chinese adults.

BACKGROUND
Experimental preeclampsia (ePE) has been shown to have worsened outcome from stroke. We investigated the effect of low-dose aspirin, known to prevent preeclampsia, on stroke hemodynamics and outcome, and the association between the vasoconstrictor and vasodilator cyclooxygenase products thromboxane A and prostacyclin.
METHODS AND RESULTS
Middle cerebral artery occlusion was performed for 3 hours with 1 hour of reperfusion in normal pregnant rats on day 20 of gestation and compared with ePE treated with vehicle or low-dose aspirin (1.5 mg/kg per day). Multisite laser Doppler was used to measure changes in cerebral blood flow to the core middle cerebral artery and collateral vascular territories. After 30 minutes occlusion, phenylephrine was infused to increase blood pressure and assess cerebral blood flow autoregulation. Infarct and edema were measured using 2,3,5-triphenyltetrazolium chloride staining. Plasma levels of thromboxane A, prostacyclin, and inflammatory markers in plasma and cyclooxygenase levels in cerebral arteries were measured. ePE had increased infarction compared with normal pregnant rats (<0.05) that was reduced by aspirin (<0.001). ePE also had intact cerebral blood flow autoregulation and reduced collateral perfusion during induced hypertension that was also prevented by aspirin. Aspirin increased prostacyclin in ePE (<0.05) without reducing thromboxane B, metabolite of thromboxane A, or 8-isoprostane-prostaglandin-2α, a marker of lipid peroxidation. There were no differences in cyclooxygenase levels in cerebral arteries between groups.
CONCLUSIONS
Low-dose aspirin in ePE reduced infarction that was associated with increased vasodilator prostacyclin and improved collateral perfusion during induced hypertension. The beneficial effect of aspirin on the brain and cerebral circulation is likely multifactorial and worth further study.

BACKGROUND
Although living alone versus with others is a key social element for cardiovascular prevention in diabetes, evidence is lacking about whether the benefit of intensive glycemic and blood pressure (BP) control differs by living arrangements. We thus aim to investigate heterogeneity in the joint effect of intensive glycemic and BP control on cardiovascular events by living arrangements among participants with diabetes.
METHODS AND RESULTS
This study included 4731 participants with diabetes in the ACCORD-BP (Action to Control Cardiovascular Risk in Diabetes-Blood Pressure) trial. They were randomized into 4 study arms, each with glycated hemoglobin target (intensive, <6.0% versus standard, 7.0-7.9%) and systolic BP target (intensive, <120 mm Hg versus standard <140 mm Hg). Cox proportional hazard models were used to estimate the joint effect of intensive glycemic and BP control on the composite cardiovascular outcome according to living arrangements. At a mean follow-up of 4.7 years, the cardiovascular outcome was observed in 445 (9.4%) participants. Among participants living with others, intensive treatment for both glycemia and BP showed decreased risk of cardiovascular events compared with standard treatment (hazard ratio [HR], 0.68 [95% CI, 0.51-0.92]). However, this association was not found among participants living alone (HR, 0.96 [95% CI, 0.58-1.59]). for interaction between intensive glycemic and BP control was 0.53 among participants living with others and 0.009 among those living alone ( value for 3-way interaction including living arrangements was 0.049).
CONCLUSIONS
We found benefits of combining intensive glycemic and BP control for cardiovascular outcomes among participants living with others but not among those living alone. Our study highlights the critical role of living arrangements in intensive care among patients with diabetes.

BACKGROUND
A limited number of studies investigated the association between blood pressure variability (BPV) and cognitive impairment in patients with hypertension. This study aimed to identify the longitudinal association between BPV and cognitive decline and the role of blood pressure (BP) control in this association.
METHODS AND RESULTS
Participants with hypertension from the HRS (Health and Retirement Study), the ELSA (English Longitudinal Study of Ageing), and the CHARLS (China Health and Retirement Longitudinal Study) were included. Variation independent of the mean (VIM) was adopted to measure BPV. Cognitive function was measured by standard questionnaires, and a standardized score was calculated. Linear mixed-model and restricted cubic splines were adopted to explore the association between BPV and cognitive decline. The study included 4853, 1616, and 1432 eligible patients with hypertension from the HRS, ELSA, and CHARLS, respectively. After adjusting for covariates, per-SD increment of VIM of BP was significantly associated with global cognitive function decline in scores in both systolic BP (pooled β, -0.045 [95% CI, -0.065 to -0.029]) and diastolic BP (pooled β, -0.022 [95% CI, -0.040 to -0.004]) among hypertensive patients. Similar inverse associations were observed in patients with hypertension taking antihypertensive drugs and in patients with hypertension with well-controlled BP.
CONCLUSIONS
High BPV was independently associated with a faster cognitive decline among patients with hypertension, even those with antihypertensive medications or well-controlled BP. Further studies are needed to confirm our results and determine whether reducing BPV can prevent or delay cognitive decline.

Indian Journal of Public Health Oct 2023The augmentation of precautionary behaviors through the application of health belief model (HBM) constructs could help in curbing the current pandemic.
BACKGROUND
The augmentation of precautionary behaviors through the application of health belief model (HBM) constructs could help in curbing the current pandemic.
OBJECTIVES
The objectives are to assess adherence to CAB and to evaluate its predictors using the constructs of HBM among COVID-19 vaccinees in Himachal Pradesh.
MATERIALS AND METHODS
A cross-sectional study using a telephone survey, with two-step stratified random sampling, was employed to acquire a sample of 441 respondents from Himachal Pradesh. Formal interviews were conducted using pretested, structured, self-administered questionnaires.
RESULTS
The mean age of respondents was 32.16 years (standard deviation = 12.77; range = 18-78 years). Maximum adherence was seen for wearing masks at 83% (95% confidence interval [CI]: 79.3%-86.3%), followed by maintenance of respiratory hygiene at 72.3% (95% CI 68%-78.4%). Nearly 42.2% (95% CI 37.6%-47.8%) conformed to social distancing norms. We observed minimum adherence for handwashing practices of 12.9% (95% CI 10%-16.3.0%). On bivariate analyses, except for perceived severity, all HBM constructs were significantly associated with CAB. However, after adjusting for gender, age, education, area of residence, and reduced income in multivariate analysis, perceived susceptibility, perceived barriers, and exposure to cues to action remained significant predictors of CAB.
CONCLUSIONS
The study highlights the empirical evidence of the application of HBM constructs to enhance behavioral adherence to COVID-19 precautionary measures.

BACKGROUND
The shift of focus toward pandemic control had an impact on public health issues that need to be addressed. As the impact may vary in the different areas based on COVID-19 cases and strictness of measures to control the disease, studying the local situation and related factors is essential to strengthening the TB program.
OBJECTIVES
The objective is to compare the TB care before and during the COVID-19 pandemic and to explore the challenges faced by stakeholders during the pandemic.
MATERIALS AND METHODS
A mixed method study was conducted in Puducherry with a quantitative phase involving data extraction from the National TB Elimination Programme (NTEP), followed by in-depth interviews to explore the challenges faced by stakeholders.
RESULTS
In 2020, there were 67% and 23% reductions in number of presumptive TB case and notified TB cases, respectively, while the decline was lesser in the year 2021 (reduction of 59% and 13%, respectively). The main challenges faced in providing and accessing TB care were social stigma, lockdown restrictions, fear of getting COVID-19, redeployment of staff to COVID-19-related activities and increased COVID-19 workload.
CONCLUSIONS
There is a need to strengthen active case finding for the missed TB cases through the mobile vans equipped with diagnostics, combined testing for COVID-19 and TB, greater inclusion of private sector and dispensaries as well as community awareness for stigma prevention.

INTRODUCTION
Because of COVID's impact on social behavior, students have become more reliant on computer-facilitated communication to continue their studies and interact with friends. While it is known that the association between screen exposure and psychological well-being is both harmful and stronger among adolescents than younger children, what is less studied are the causal factors that may mediate the relationship.
OBJECTIVES
The objectives of this study were to analyze the relationship between screen exposure and two psychological outcomes, sleep quality and loneliness, using digital eye strain as a mediating factor. Eye strain is expected to have a direct and harmful influence on psychological well-being.
MATERIALS AND METHODS
A structured and validated questionnaire was transcribed and administered online. A nonrepresentative sample of 497 female college students in a North Indian city participated in the study. Digital eye strain, quality of sleep, and feeling of loneliness scores were assessed using latent class analysis.
RESULTS
The selected latent model suggested that Class 2 had a high percentage of students with network issues, the problem with space and noise, and various financial hardships, which had almost doubled the rate of loneliness (53.28%) and sleep-wake difficulties (75.41%) among the students affected with computer vision syndrome (89.75%).
CONCLUSION
There is an urgent need to examine the implications of digital exposure across gender and age to prevent future complications. Further, awareness for improving holistic well-being in the digital era should be promoted through various platforms.

BACKGROUND
To trigger quit intention and practice of preventive measures for COVID-19 among tobacco users; it is imperative for them to be well aware of the fact that they are at higher risk of COVID-19 infection and should be at higher efficacy to practice preventive measures for the disease as compared to nonusers of tobacco.
OBJECTIVES
This community-based cross-sectional analytical study was conducted from April 2020 to May 2020 among 1203 adult participants to compare the threat and efficacy perception among users and nonusers of tobacco.
MATERIALS AND METHODS
Perception of threat was assessed using three questions on perceived threat and one question on perceived susceptibility; whereas perception of efficacy was assessed using four questions each on self-efficacy and response efficacy through telephonic interview.
RESULTS
There was no significant difference in the overall threat perception among users and nonusers of tobacco. However, state-wise analysis showed that tobacco users had higher perception of threat for SARS-CoV-2 infection in all the states except Telangana. The overall perception of efficacy among tobacco users was significantly higher as compared to nonusers of tobacco.
CONCLUSION
The study calls for active collaboration between tobacco control enthusiasts and the Government to promote awareness of a higher risk of COVID-19 disease among tobacco users. In essence, the study's implications extend beyond COVID-19 and can guide targeted efforts to promote awareness, behavior change, and collaboration in the context of other infectious diseases among tobacco users.
