    BACKGROUND: The rapid rise of non-communicable diseases, particularly type 2 diabetes mellitus (T2DM), poses a significant global public health challenge, with South Asia experiencing an increasingly severe burden. This study aimed to analyse historical trends of T2DM across South Asia from 1990 to 2021 and forecast incidence through 2031.

    RESEARCH DESIGN AND METHODS: We carried out analysis based on the data from the 2021 Global burden of disease study. Joinpoint regression was used to identify significant changes in trends over time, and ARIMA models were applied to forecast incidence rates.

    RESULTS: Between 1990 and 2021, the average annual percentage change (AAPC) of age-standardized prevalence rates and incidence rates increased by 2.15 and 1.72 respectively. The age-standardized mortality rate rose more slowly, at 1.05 AAPC, with females experiencing a slightly higher AAPC than males. ARIMA forecasts suggest that by 2031, T2DM incidence rates will continue to rise significantly across all South Asian countries.

    CONCLUSIONS: This study highlights the need for public health policies focused on preventing obesity, promoting physical activity, and improving healthcare access. It also calls for addressing regional disparities in T2DM prevalence and mortality to better allocate resources and prioritize policies to combat the diabetes epidemic inSouth Asia.

    Sex hormone-binding globulin (SHBG) regulates sex hormone availability and is influenced by metabolic factors. Variations in SHBG levels during pregnancy may affect the development of hypertensive disorders such as gestational hypertension (GH) and preeclampsia (PE). This systematic review and meta-analysis explores the potential of SHBG as a biomarker for predicting GH and PE. A search of PubMed, Embase, and Web of Science was conducted to identify studies evaluating the association between SHBG levels and the risk of HDP, including GH and PE. Inclusion criteria encompassed observational studies reporting quantitative risk estimates (risk ratios, odds ratios, or hazard ratios) for SHBG levels. Results were pooled using a random-effects meta-analysis in R software (V 4.4), with the I2 statistic assessing heterogeneity. Eight studies were included in the systematic review from a total of 592 screened records. The association between SHBG levels and the risk of any HDP showed a pooled OR of 0.875 (95% CI: 0.772-0.993), for PE 0.890 (95% CI: 0.767-1.032), and for GH 0.729 (95% CI: 0.442-1.205), suggesting significant association between SHBG and HDP. Sensitivity analysis validated the robustness of the findings. This meta-analysis found potential significant association between higher SHBG levels and risk of HDP. Further high-quality research is required to better understand the role of SHBG in pregnancy-related hypertensive disorders. Future studies should consider larger sample sizes, more precise measurement techniques, and explore potential confounding factors to clarify the potential utility of SHBG as a biomarker for predicting GH and PE.

    BACKGROUND: Dengue and leptospirosis are prominent vector-borne diseases in tropical and subtropical regions, sharing overlapping geographic distribution and clinical presentations, which complicates diagnosis and management. Co-infection of these pathogens places additional strain on healthcare resources in endemic areas. This study aims to systematically estimate the prevalence and mortality rates of dengue and leptospirosis co-infections and assess their clinical implications.

    METHODS: Adhering the PRISMA 2020 guidelines and registered in the PROSPERO database, we conducted a systematic review and meta-analysis using the PubMed, Embase, and Web of Science databases up to October 2024. Nested Knowledge was used for screening and data extraction. Studies reporting quantitative data on the prevalence or mortality of dengue and leptospirosis co-infections were included. Data extraction and quality assessment were performed independently by two reviewers using the Modified Newcastle-Ottawa Scale. Statistical analyses, including prevalence and mortality estimation, sensitivity analysis were conducted using R, with heterogeneity evaluated by the I² statistic.

    RESULTS: Out of 3,982 records, 14 studies met the eligibility criteria, yielding a pooled prevalence of dengue and leptospirosis co-infection at 2.33% (95% CI: 1.41-3.46%) across 16,638 participants, with significant heterogeneity (I² = 90%). The prediction interval for co-infection ranged from 0.05 to 7.27%. The pooled mortality rate among co-infected patients was 9.96% (95% CI: 0-53.49%), with moderate heterogeneity (I² = 71%). The prediction interval for mortality ranged from 0.00 to 100%. Publication bias was indicated by an LFK index of 2.52.

    CONCLUSION: This meta-analysis revealed a moderate prevalence and a notable mortality rate for dengue and leptospirosis co-infections, with significant variability observed across different studies. Further research into the immunopathology and the implementation of integrated surveillance systems could enhance the effectiveness of diagnosis and treatment strategies in regions where these diseases are endemic.

    OBJECTIVE: Asthma poses a significant health burden in South Asia, with increasing incidence and mortality despite a global decline in age-standardized prevalence rates. This study aims to analyze asthma trends from 1990 to 2021, focusing on prevalence, incidence, mortality, and disability-adjusted life years (DALYs) across South Asia. The study also assesses the impact of risk factors like high body mass index (BMI), smoking, and occupational exposures on asthma outcomes.

    METHOD: We extracted asthma data from the Global Burden of Disease database for South Asia (1990-2021). Joinpoint regression analysis was used to assess temporal trends in asthma burden. Total Percentage change (TPC) in age-standardized rates of incidence, mortality, and DALYs were calculated. Data were stratified by gender, and the contribution of risk factors was evaluated.

    RESULTS: Asthma-related mortality in South Asia decreased by 37%, from 27.78 per 100,000 (1990) to 17.54 per 100,000 (2021). The Maldives showed the most significant reduction in mortality (78.31%), while Bangladesh recorded a 47.44% reduction in prevalence and a 62.64% decrease in DALYs. High BMI, smoking, and environmental risks contributed significantly to DALYs, with environmental factors playing a major role in countries like Afghanistan (20.73%) and Bhutan (18.58%). Females, particularly those over 20, experienced higher asthma-related DALYs than males.

    CONCLUSION: Asthma burden in South Asia has reduced over the past three decades, yet the absolute number of cases continues to rise, driven by population growth and environmental risk factors. Targeted interventions addressing risk factors and healthcare disparities are essential for further reducing asthma burden.

    BACKGROUND: Cannabis is the third most widely used psychoactive substance globally, and its consumption has been increasing, particularly with the growing trend of legalization for medicinal and recreational use. Recent studies have raised concerns about the potential impact of cannabis on respiratory health, specifically the risk of asthma, a significant public health concern. This systematic review aimed to consolidate research on the association between cannabis use and the risk of asthma.

    METHODS: A comprehensive search was conducted across PubMed, Embase, and Web of Science, covering studies published up to September 30, 2024. We included peer-reviewed observational studies evaluating the link between cannabis consumption and the risk of asthma diagnosis. Data synthesis employed a random-effects meta-analysis to account for heterogeneity. R statistical software (version 4.4) was used for statistical analyses.

    RESULTS: The search yielded 8 relevant studies after screening 1,887 records. The pooled odds ratio (OR) for the association between cannabis consumption and the risk of asthma diagnosis was 1.31, 95% confidence interval (CI): 1.19-1.44, indicating greater odds of having asthma compared to non-users. Moderate heterogeneity was observed (I² = 46%), and sensitivity analysis confirmed the robustness of the findings.

    CONCLUSION: This systematic review and meta-analysis identifies a significant association between cannabis use and greater odds of having asthma. These findings emphasize the importance of raising awareness about the potential respiratory risks associated with cannabis use. Future research should prioritize identifying moderating factors, such as the frequency and mode of cannabis consumption, to enhance understanding of this association and provide a stronger evidence base for potential public health interventions.

    BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality globally, particularly in low- and middle-income countries like India. This study aims to analyze regional trends and project future burden of COPD in India using data from the Global Burden of Disease (GBD) 1990-2021.

    METHODS: This analysis utilized data from the GBD study to assess age-standardized prevalence (ASPR), incidence (ASIR), disability-adjusted life years (DALYs) (ASDR), and mortality rates (ASMR) for COPD across Indian states. Joinpoint regression was used to analyze temporal trends, while ARIMA models predicted future incidence rates.

    RESULTS: In 2021, the highest ASIR was observed in Rajasthan at 306.28, and the highest ASMR was observed in Uttarakhand at 227.19. Projections suggest that the ASIR for COPD in India will decrease from 265.16 in 2022 to 258.19 by 2031. The heatmap analysis identified states like Uttarakhand and Rajasthan as having the highest DALYs attributable to COPD risk factors, including air pollution and tobacco use.

    CONCLUSION: COPD remains a public health challenge in India, with regional variability. Targeted interventions addressing air pollution, smoking cessation, and improved healthcare access are essential to mitigate the disease's future burden, particularly in high-risk regions.

    BACKGROUND: Atrial fibrillation (AF) is the most prevalent form of sustained cardiac arrhythmia, with vascular endothelial growth factor (VEGF) increasingly recognized for its potential role in the pathogenesis of AF through mechanisms involving atrial remodeling, inflammation, and fibrosis. This systematic review aims to synthesize available evidence on the association between VEGF and AF, exploring the implications of VEGF as a biomarker and therapeutic target.

    METHODS: We conducted a comprehensive search across PubMed, Embase, and Web of Science until November 10 2024, selecting studies based on pre-defined criteria that involve adults with AF and measurements of VEGF levels. The selected studies included observational and experimental designs, excluding non-English and methodologically insufficient publications. Narrative synthesis was used for summarising the results.

    RESULTS: Eight studies met the inclusion criteria. The studies show a general trend of elevated VEGF levels in AF patients compared to controls, with significant heterogeneity in findings across studies. VEGF subtypes such as VEGF-A and VEGF-D demonstrated stronger associations with AF risk compared to VEGF-C. These variations point to the complex role of VEGF in AF, influencing factors like angiogenesis, endothelial function, and inflammatory responses.

    CONCLUSION: VEGF is potentially a significant contributor to AF pathophysiology, with its levels reflecting disease activity. The variability observed across studies suggests a need for standardized measurement approaches and further investigation into VEGF subtypes. Future research should focus on longitudinal studies to better understand the causal relationships and the potential of VEGF as a therapeutic target and biomarker in AF management.

    BACKGROUND: Prostate cancer is one of the most prevalent malignancies among men globally. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs), primarily used for type 2 diabetes mellitus (T2DM) management, have been investigated for their potential effects on cancer risks. This systematic review and meta-analysis aimed to assess the association between GLP-1 RA use and risk reduction of prostate cancer.

    METHODS: A comprehensive literature search was conducted across PubMed, Embase, and Web of Science up to July 30, 2024. Studies that met the inclusion criteria randomized controlled trials, cohort studies, case-control studies, and observational studies assessing the incidence of prostate cancer in GLP-1 RA-treated patients were included. The quality of studies was evaluated using the Newcastle-Ottawa Scale and the Cochrane Risk of Bias tool. Meta-analysis was performed using a random effects model.

    RESULTS: A total of five studies were included, analyzing data from diverse international contexts. The included studies showed a reduced risk of prostate cancer with both adjusted and unadjusted effect estimates with GLP-1 RAs. The meta-analysis revealed an RR of 0.72 (95% CI: 0.610 to 0.832), indicating a statistically significant 28% reduction in prostate cancer risk associated with GLP-1 RA use compared to placebo or other antidiabetic drugs. Moderate heterogeneity was observed (I2 = 51%). Sensitivity analysis confirmed the results.

    CONCLUSION: The findings suggest a significant protective association between GLP-1 RA use and reduced prostate cancer risk in men, particularly those with T2DM. This supports the potential of GLP-1 RAs not only in diabetes management but also as a strategy to mitigate cancer risk. Further research is required to confirm these findings and explore the underlying mechanisms, considering different dosages, durations of therapy, and patient subgroups based on demographic and metabolic characteristics.

    PURPOSE: Diabetic retinopathy (DR) is a leading cause of vision loss worldwide, making early detection critical to prevent blindness. IDX-DR, an FDA-approved autonomous artificial intelligence (AI) system, has emerged as an innovative solution to improve access to DR screening. This systematic review and meta-analysis aimed to evaluate the diagnostic accuracy of IDX-DR in detecting diabetic retinopathy.

    DESIGN: Systematic review and meta-analysis.

    METHODS: A comprehensive literature search was conducted across PubMed, Embase, Scopus and Web of Science, identifying studies published through October 5, 2024. Studies involving adult patients with Type 1 or Type 2 diabetes and reporting diagnostic metrics such as sensitivity and specificity were included. The primary outcomes were pooled sensitivity and specificity of IDX-DR. A bivariate random-effects model was used for meta-analysis, and summary receiver operating characteristic (SROC) curves were generated to assess diagnostic performance. Statistical analyses were performed using MetaDisc software version 2.0.

    RESULTS: Thirteen studies involving 13,233 participants met the inclusion criteria. IDX-DR's pooled sensitivity was 0.95 (95% CI: 0.82-0.99), and its pooled specificity was 0.91 (95% CI: 0.84-0.95). The SROC curve confirmed IDX-DR's high diagnostic accuracy in detecting diabetic retinopathy across various clinical environments. The AUC value of 0.95 demonstrated high sensitivity and specificity, indicating a robust diagnostic performance for IDX-DR in detecting diabetic retinopathy.

    CONCLUSION: IDX-DR is a highly effective diagnostic tool for diabetic retinopathy screening, with robust sensitivity and good specificity. Its integration into clinical practice, especially in resource-limited settings, can potentially improve early detection and reduce vision loss. However, careful implementation is needed to address challenges such as over-diagnosis and ensure the tool complements clinical judgment. Future studies should explore the long-term impacts of AI-based screening and address ethical considerations surrounding its use.

    BACKGROUND: Neonatal disorders represent a significant public health challenge, particularly in low- and middle-income countries, where they account for 79% of global neonatal mortality. South Asia, comprising countries such as India, Pakistan, Bangladesh, Nepal, and Bhutan, bears a disproportionately high burden, contributing to 38% of the world's neonatal deaths. Despite notable progress, South Asia remains off track in meeting the Sustainable development goals (SDG). This study aims to assess the current burden, trends in neonatal disorders, and forecast mortality rates across South Asian countries, providing insights to guide investment priorities and improve neonatal outcomes.

    METHODS: Data for this study were sourced from the Global burden of disease (GBD) 2021 study, which utilizes a Bayesian meta-regression model to estimate mortality, prevalence, and disability-adjusted life years (DALYs). Spatial maps depicting the age-standardized prevalence rate and age-standardized mortality rate for neonatal disorders in South Asia were generated using QGIS software. Mortality forecasts for the period 2022-2031, attributed to various neonatal disorders, were produced employing the Auto-Regressive Integrated Moving Average model in R software. Additionally, an analysis of overall neonatal mortality trends from 1980 to 2021 was conducted, supplemented by a heat map that compares DALYs attributable to various neonatal disorders across South Asian countries in 2021.

    RESULTS: Between 1980 and 2021, South Asia experienced a substantial decline in neonatal mortality rates, with India and Bangladesh leading the progress. Mortality decreased by 40%, while DALYs fell by 35%, despite a 15% increase in the prevalence. The prevalence of neonatal encephalopathy due to birth asphyxia and trauma surged by 355%, yet its mortality dropped by 31%. Pakistan recorded the highest neonatal mortality and disease burden, particularly for hemolytic disease and other neonatal jaundice and neonatal encephalopathy due to birth asphyxia and trauma. In India and Bangladesh, neonatal preterm birth and neonatal sepsis and other neonatal infections contributed most to mortality. Neonatal encephalopathy due to birth asphyxia and trauma accounted for the highest DALYs. Forecasts predict continued reductions in neonatal mortality across South Asia, except in Pakistan, where persistently high rates are expected till 2031.

    CONCLUSION: For South Asian countries to meet the SDG target for neonatal mortality by 2030, intensified and continuous efforts are required. These efforts should focus on identifying high-risk pregnancies and improving the quality of care during childbirth to address the root causes and reduce preventable neonatal deaths.

    BACKGROUND: Despite global progress, South Asian countries account for a disproportionate burden of Acute hepatitis E (AHE). Understanding the burden of AHE in this region is crucial for targeted interventions.

    METHODS: We used Global Burden of Disease (GBD) 2021 data to assess the burden of AHE across eight South Asian countries from 1990 to 2021. Joinpoint regression was used to analyze temporal trends and Estimated Annual Percentage Change (EAPC) was calculated to quantify trends. The relationship between age-standardized disability-adjusted life years rate (ASDR) and socio-demographic index (SDI) was assessed using smoothing spline model and Spearman rank correlation. Rates are expressed per 100,000 population.

    RESULTS: Bangladesh had highest age-standardized prevalence rate (ASPR) [33.27 (95 % Uncertainty Interval: 27.64 to 39.95)] and age-standardized incidence rate (ASIR) [433.01 (359.61 to 519.76)], while India had highest ASDR [9.52 (4.33 to 18.42)]. Males had higher ASIR and ASPR than females in most South Asian countries, except Bhutan and India, and higher ASDR except in Nepal and Pakistan. Bhutan had the highest EAPC for both sexes in ASPR and ASIR, while India had the highest EAPC in ASDR, closely followed by Bhutan for both sexes. Age group 5-9 had the highest ASPR and ASIR whereas <1-year age group had the highest ASDR. There was an inverse relationship between ASDR and SDI (R = -0.49, p < 0.01).

    CONCLUSION: South Asia bears a high burden of AHE, with variations across countries. Improvements in Water Sanitation and Hygiene (WASH) services are needed to achieve Sustainable Development Goals 3 and 6.

    OBJECTIVES: The objectives of this study were to analyze trends in prostate cancer incidence, incidence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021 via data from the Global Burden of Disease (GBD) study in South Asia. Additionally, the study projects future prostate cancer incidence rates up to 2031 to inform public health interventions in South Asia.

    METHODS: Data covering South Asian countries such as Bangladesh, Bhutan, India, Nepal, and Pakistan were obtained from the GBD 2021 portal. Age-standardized rates (ASRs) for prostate cancer metrics, including incidence (ASIR), prevalence (ASPR), mortality (ASMR), and DALYs (ASDR), were analyzed via joinpoint and ARIMA modeling techniques. Geographic variations in ASRs were mapped via QGIS software.

    RESULTS: The prostate cancer ASIR, ASPR, and ASDR significantly increased from 1990 to 2021, particularly among individuals aged 60-65 years. The highest incidence and mortality rates were observed in Pakistan. The total percentage change in incidence in India was the highest at 61%. Projections indicate a continued rise in prostate cancer incidence, with South Asia's ASIR expected to reach 9.34 per 100 000 by 2031.

    CONCLUSIONS: The growing burden of prostate cancer in South Asia highlights the need for enhanced screening programs, public awareness, and healthcare infrastructure improvements. Without intervention, the increasing incidence and mortality rates could strain healthcare resources, emphasizing the urgency of region-specific public health strategies.

    BACKGROUND: Although Helicobacter pylori (H. pylori) infections are widespread throughout the world, it is yet unknown whether they are linked to systemic illnesses like dyslipidemia. The purpose of this systematic review and meta-analysis was to examine the connection between lipid metabolism and H. pylori infection, with a particular emphasis on how it affects dyslipidemia.

    METHODS: We conducted a thorough search up until October 10, 2024, across databases such as PubMed, Web of Science, and Embase. Studies that reported lipid profiles in both H. pylori-infected and non-infected patients were considered eligible. The primary outcomes were triglyceride, LDL-C, HDL-C, and total cholesterol levels, which were examined using a random-effects model in R software version 4.4.

    RESULTS: There were 17 studies with more than 150,000 participants from 681 screened publications. Higher levels of LDL (MD: 5.32 mg/dL; 95% CI: 1.315 to 9.319) and total cholesterol (MD: 6.28 mg/dL; 95% CI: 0.718 to 11.842), as well as lower levels of HDL (MD: -2.06 mg/dL; 95% CI: -3.212 to -0.915), were the results of the meta-analysis. Among those infected, triglyceride levels were likewise higher (MD: 7.93 mg/dL; 95% CI: 0.413 to 15.436), but the odds ratio (OR) did not show a significant increase in risk (OR: 1.002; 95% CI: 0.995 to 1.010).

    CONCLUSION: H. pylori infection is associated with significant dyslipidemia, suggesting a potential link between chronic bacterial infection and lipid metabolism. The findings emphasize the need for further research to explore the mechanisms and potential therapeutic interventions.

    BACKGROUND: Electronic Nicotine Delivery Systems (ENDS), commonly known as e-cigarettes or vapes, have gained widespread popularity, particularly among young adults and former smokers. While marketed as a harm reduction tool, concerns have emerged regarding their long-term impact on respiratory health, particularly their association with chronic obstructive pulmonary disease (COPD). This systematic review and meta-analysis aimed to evaluate the relationship between ENDS use and COPD risk while considering tobacco smoking as a key confounder.

    METHODS: A comprehensive search was conducted across PubMed, Embase, and Web of Science for studies published up to September 20, 2024. Observational studies assessing the association between ENDS use and COPD risk were included. A random-effects meta-analysis was performed using R statistical software (version 4.4). Tobacco smoking, a key confounder in COPD research, was accounted for in many included studies, with adjustments varying across studies.

    RESULTS: Fifteen studies met the inclusion criteria. The pooled odds ratio (OR) for current ENDS use and COPD risk was 1.488 (95 % CI: 1.363-1.623). Former ENDS users had an OR of 1.839 (95 % CI: 1.513-2.234), and ever-users had an OR of 1.787 (95 % CI: 1.421-2.247). Sensitivity analyses confirmed the robustness of findings, and no publication bias was detected.

    CONCLUSION: This meta-analysis provides evidence of a significant association between ENDS use and increased COPD risk, even after adjusting for tobacco smoking. Future research should standardize smoking adjustments and investigate the independent impact of ENDS use on COPD.

    Advancements in personalized neoantigen-based cancer vaccines are ushering in a new era in oncology, targeting unique genetic alterations within tumors to enhance treatment precision and efficacy. Neoantigens, specific to cancer cells and absent in normal tissues, are at the heart of these vaccines, promising to direct the immune system specifically against the tumor, thereby maximizing therapeutic efficacy while minimizing side effects. The identification of neoantigens through genomic and proteomic technologies is central to developing these vaccines, allowing for the precise mapping of a tumor's mutational landscape. Despite advancements, accurately predicting which neoantigens will elicit strong immune responses remains challenging due to tumor variability and the complexity of immune system interactions. This necessitates further refinement of bioinformatics tools and predictive models. Moreover, the efficacy of these vaccines heavily depends on innovative delivery methods that enhance neoantigen presentation to the immune system. Techniques like encapsulating neoantigens in lipid nanoparticles and using viral vectors are critical for improving vaccine stability and delivery. Additionally, these vaccines contribute towards achieving Sustainable Development Goal 3.8, promoting universal health coverage by advancing access to safe and effective cancer treatments. This review delves into the potential of neoantigen-based vaccines to transform cancer treatment, examining both revolutionary advancements and the ongoing challenges they face.

    BACKGROUND: To our knowledge, no previous study has prospectively documented the incidence of common diseases and related mortality in high-income countries (HICs), middle-income countries (MICs), and low-income countries (LICs) with standardised approaches. Such information is key to developing global and context-specific health strategies. In our analysis of the Prospective Urban Rural Epidemiology (PURE) study, we aimed to evaluate differences in the incidence of common diseases, related hospital admissions, and related mortality in a large contemporary cohort of adults from 21 HICs, MICs, and LICs across five continents by use of standardised approaches.

    METHODS: The PURE study is a prospective, population-based cohort study of individuals aged 35-70 years who have been enrolled from 21 countries across five continents. The key outcomes were the incidence of fatal and non-fatal cardiovascular diseases, cancers, injuries, respiratory diseases, and hospital admissions, and we calculated the age-standardised and sex-standardised incidence of these events per 1000 person-years.

    FINDINGS: This analysis assesses the incidence of events in 162 534 participants who were enrolled in the first two phases of the PURE core study, between Jan 6, 2005, and Dec 4, 2016, and who were assessed for a median of 9·5 years (IQR 8·5-10·9). During follow-up, 11 307 (7·0%) participants died, 9329 (5·7%) participants had cardiovascular disease, 5151 (3·2%) participants had a cancer, 4386 (2·7%) participants had injuries requiring hospital admission, 2911 (1·8%) participants had pneumonia, and 1830 (1·1%) participants had chronic obstructive pulmonary disease (COPD). Cardiovascular disease occurred more often in LICs (7·1 cases per 1000 person-years) and in MICs (6·8 cases per 1000 person-years) than in HICs (4·3 cases per 1000 person-years). However, incident cancers, injuries, COPD, and pneumonia were most common in HICs and least common in LICs. Overall mortality rates in LICs (13·3 deaths per 1000 person-years) were double those in MICs (6·9 deaths per 1000 person-years) and four times higher than in HICs (3·4 deaths per 1000 person-years). This pattern of the highest mortality in LICs and the lowest in HICs was observed for all causes of death except cancer, where mortality was similar across country income levels. Cardiovascular disease was the most common cause of deaths overall (40%) but accounted for only 23% of deaths in HICs (vs 41% in MICs and 43% in LICs), despite more cardiovascular disease risk factors (as judged by INTERHEART risk scores) in HICs and the fewest such risk factors in LICs. The ratio of deaths from cardiovascular disease to those from cancer was 0·4 in HICs, 1·3 in MICs, and 3·0 in LICs, and four upper-MICs (Argentina, Chile, Turkey, and Poland) showed ratios similar to the HICs. Rates of first hospital admission and cardiovascular disease medication use were lowest in LICs and highest in HICs.

    INTERPRETATION: Among adults aged 35-70 years, cardiovascular disease is the major cause of mortality globally. However, in HICs and some upper-MICs, deaths from cancer are now more common than those from cardiovascular disease, indicating a transition in the predominant causes of deaths in middle-age. As cardiovascular disease decreases in many countries, mortality from cancer will probably become the leading cause of death. The high mortality in poorer countries is not related to risk factors, but it might be related to poorer access to health care.

    OBJECTIVE: To examine the association between social isolation and mortality and incident diseases in middle-aged adults in urban and rural communities from high-income, middle-income and low-income countries.

    DESIGN: Population-based prospective observational study.

    SETTING: Urban and rural communities in 20 high income, middle income and low income.

    PARTICIPANTS: 119 894 community-dwelling middle-aged adults.

    MAIN OUTCOME MEASURES: Associations of social isolation with mortality, cardiovascular death, non-cardiovascular death and incident diseases.

    RESULTS: Social isolation was more common in middle-income and high-income countries compared with low-income countries, in urban areas than rural areas, in older individuals and among women, those with less education and the unemployed. It was more frequent among smokers and those with a poorer diet. Social isolation was associated with greater risk of mortality (HR of 1.26, 95% CI: 1.17 to 1.36), incident stroke (HR: 1.23, 95% CI: 1.07 to 1.40), cardiovascular disease (HR: 1.15, 95% CI: 1.05 to 1.25) and pneumonia (HR: 1.22, 95% CI: 1.09 to 1.37), but not cancer. The associations between social isolation and mortality were observed in populations in high-income, middle-income and low-income countries (HR (95% CI): 1.69 (1.32 to 2.17), 1.27 (1.15 to 1.40) and 1.47 (1.25 to 1.73), respectively, interaction p=0.02). The HR associated with social isolation was greater in men than women and in younger than older individuals. Mediation analyses for the association between social isolation and mortality showed that unhealthy behaviours and comorbidities may account for about one-fifth of the association.

    CONCLUSION: Social isolation is associated with increased risk of mortality in countries at different economic levels. The increasing share of older people in populations in many countries argues for targeted strategies to mitigate its adverse effects.

    BACKGROUND: Some studies, mainly from high-income countries (HICs), report that women receive less care (investigations and treatments) for cardiovascular disease than do men and might have a higher risk of death. However, very few studies systematically report risk factors, use of primary or secondary prevention medications, incidence of cardiovascular disease, or death in populations drawn from the community. Given that most cardiovascular disease occurs in low-income and middle-income countries (LMICs), there is a need for comprehensive information comparing treatments and outcomes between women and men in HICs, middle-income countries, and low-income countries from community-based population studies.

    METHODS: In the Prospective Urban Rural Epidemiological study (PURE), individuals aged 35-70 years from urban and rural communities in 27 countries were considered for inclusion. We recorded information on participants' sociodemographic characteristics, risk factors, medication use, cardiac investigations, and interventions. 168 490 participants who enrolled in the first two of the three phases of PURE were followed up prospectively for incident cardiovascular disease and death.

    FINDINGS: From Jan 6, 2005 to May 6, 2019, 202 072 individuals were recruited to the study. The mean age of women included in the study was 50·8 (SD 9·9) years compared with 51·7 (10) years for men. Participants were followed up for a median of 9·5 (IQR 8·5-10·9) years. Women had a lower cardiovascular disease risk factor burden using two different risk scores (INTERHEART and Framingham). Primary prevention strategies, such as adoption of several healthy lifestyle behaviours and use of proven medicines, were more frequent in women than men. Incidence of cardiovascular disease (4·1 [95% CI 4·0-4·2] for women vs 6·4 [6·2-6·6] for men per 1000 person-years; adjusted hazard ratio [aHR] 0·75 [95% CI 0·72-0·79]) and all-cause death (4·5 [95% CI 4·4-4·7] for women vs 7·4 [7·2-7·7] for men per 1000 person-years; aHR 0·62 [95% CI 0·60-0·65]) were also lower in women. By contrast, secondary prevention treatments, cardiac investigations, and coronary revascularisation were less frequent in women than men with coronary artery disease in all groups of countries. Despite this, women had lower risk of recurrent cardiovascular disease events (20·0 [95% CI 18·2-21·7] versus 27·7 [95% CI 25·6-29·8] per 1000 person-years in men, adjusted hazard ratio 0·73 [95% CI 0·64-0·83]) and women had lower 30-day mortality after a new cardiovascular disease event compared with men (22% in women versus 28% in men; p<0·0001). Differences between women and men in treatments and outcomes were more marked in LMICs with little differences in HICs in those with or without previous cardiovascular disease.

    INTERPRETATION: Treatments for cardiovascular disease are more common in women than men in primary prevention, but the reverse is seen in secondary prevention. However, consistently better outcomes are observed in women than in men, both in those with and without previous cardiovascular disease. Improving cardiovascular disease prevention and treatment, especially in LMICs, should be vigorously pursued in both women and men.

    Importance: Obesity is a growing public health threat leading to serious health consequences. Late bedtime and sleep loss are common in modern society, but their associations with specific obesity types are not well characterized.

    Objective: To assess whether sleep timing and napping behavior are associated with increased obesity, independent of nocturnal sleep length.

    Design, Setting, and Participants: This large, multinational, population-based cross-sectional study used data of participants from 60 study centers in 26 countries with varying income levels as part of the Prospective Urban Rural Epidemiology study. Participants were aged 35 to 70 years and were mainly recruited during 2005 and 2009. Data analysis occurred from October 2020 through March 2021.

    Exposures: Sleep timing (ie, bedtime and wake-up time), nocturnal sleep duration, daytime napping.

    Main Outcomes and Measures: The primary outcomes were prevalence of obesity, specified as general obesity, defined as body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) of 30 or greater, and abdominal obesity, defined as waist circumference greater than 102 cm for men or greater than 88 cm for women. Multilevel logistic regression models with random effects for study centers were performed to calculate adjusted odds ratios (AORs) and 95% CIs.

    Results: Overall, 136 652 participants (81 652 [59.8%] women; mean [SD] age, 51.0 [9.8] years) were included in analysis. A total of 27 195 participants (19.9%) had general obesity, and 37 024 participants (27.1%) had abdominal obesity. The mean (SD) nocturnal sleep duration was 7.8 (1.4) hours, and the median (interquartile range) midsleep time was 2:15 am (1:30 am-3:00 am). A total of 19 660 participants (14.4%) had late bedtime behavior (ie, midnight or later). Compared with bedtime between 8 pm and 10 pm, late bedtime was associated with general obesity (AOR, 1.20; 95% CI, 1.12-1.29) and abdominal obesity (AOR, 1.20; 95% CI, 1.12-1.28), particularly among participants who went to bed between 2 am and 6 am (general obesity: AOR, 1.35; 95% CI, 1.18-1.54; abdominal obesity: AOR, 1.38; 95% CI, 1.21-1.58). Short nocturnal sleep of less than 6 hours was associated with general obesity (eg, <5 hours: AOR, 1.27; 95% CI, 1.13-1.43), but longer napping was associated with higher abdominal obesity prevalence (eg, ≥1 hours: AOR, 1.39; 95% CI, 1.31-1.47). Neither going to bed during the day (ie, before 8pm) nor wake-up time was associated with obesity.

    Conclusions and Relevance: This cross-sectional study found that late nocturnal bedtime and short nocturnal sleep were associated with increased risk of obesity prevalence, while longer daytime napping did not reduce the risk but was associated with higher risk of abdominal obesity. Strategic weight control programs should also encourage earlier bedtime and avoid short nocturnal sleep to mitigate obesity epidemic.
