Social skills programme for adolescents with depression: initial outcomes of a hospital based study in Sri Lanka.

OBJECTIVE: This quasi-experimental study aimed to describe the outcome of a social skills intervention for adolescents with depression followed up at an outpatient Child and Adolescent Psychiatry Unit. Twenty adolescents with depression attending a tertiary care facility in Colombo, Sri Lanka were recruited, who participated in two social skills training programmes (6 months apart), in addition to pharmacological treatment. Outcome of the programme was measured by a self-administered questionnaire that assessed perceived changes in social skills, before and after the intervention. Wilcoxon Signed Rank test was used to determine the statistical significance of improvement in social skills. RESULTS: The sample consisted of 80% (n = 16) female adolescents. Median scores (inter-quartile range) for social skills before and after the first social skills programme were 31.5 (21.0-36.0) and 33.0 (28.25-40.25) respectively, indicating a significant improvement in social skills following intervention (p = 0.011, r = 0.57). A similar improvement was observed after the second programme (n = 10), reporting higher median scores for social skills after intervention (29.5 vs. 37.5, p = 0.005, r = 0.89). A significant improvement was also observed in perceived ability to cope with depressive thoughts after intervention (p = 0.032), indicating that social skills training can be a useful adjunct to pharmacological interventions, in the management of depression in adolescents.

Chronic obstructive pulmonary disease attributable to air pollution in the South Asian countries: global burden of disease study 1990 - 2019.

This study investigates the burden of COPD attributable to air pollution in South Asia using data from the Global Burden of Disease Study from 1990 to 2019. Method Data for this study were obtained from the Global Burden of Disease Study 2019. The burden was measured in terms of death, disability-adjusted life years (DALYs), and Years of life lost (YLLs). Results Since 1990, several countries in South Asia registered substantial declines in mortality rates attributed to COPD, ranging from -37.47% in Pakistan to -66.25% in Bangladesh. Similar trends were observed for DALYs and YLLs as well, which have potentially contributed to a considerable decrease in mortality rates at the regional level (-43.13%) compared to a 32.59% decline in Low SDI and 56.87% decline globally. Conclusion Despite significant declines since 1990, the burden of COPD attributable to air pollution reductions in the South Asian region's rates remains alarmingly high.

A scoping review of evidence on routine cervical cancer screening in South Asia: investigating factors affecting adoption and implementation.

NEED: Cervical cancer is a major global public health issue, particularly affecting low and middle-income countries, distinctly in the South Asian region. This geographical region lacks a well-organized routine cervical screening program. Consequently, this scoping review aimed to investigate the evidence on factors influencing the adoption and implementation of routine cervical cancer screening in South Asia. METHODS: Adopting the "Arksey and O'Malley and Levac et al." methodology, databases such as PubMed, CINAHL, Web of Science, and Scopus were scrutinized in the pursuit of relevant studies. Subsequently, the collected data were synthesized by adopting the Consolidated Framework for Implementation Research (CFIR) model. RESULTS: A total of 837 records were initially identified and screened for eligibility, including 55 studies. The successful adoption and implementation of cervical cancer screening in South Asia encounter numerous obstacles within the health system, including the absence of a comprehensive program protocol for screening, inadequate health infrastructure, and the presence of multiple sociocultural factors, such as social stigma, low levels of education, and concerns related to modesty. CONCLUSION: To optimize adoption and implementation, it is imperative to construct a customized policy framework that incorporates a risk communication strategy tailored to the specific contexts of these nations. Drawing insights from the experiences of South Asian countries in executing cervical cancer screening programs can inform the formulation of policies for similar healthcare initiatives aimed at facilitating the expansion of HPV vaccination efforts.

Flight initiation distance and bird tolerance to humans in rural and urban habitats.

Urbanization induces homogenization and changes the behavioural patterns of various bird species, thereby facilitating coexistence and prompting adaptations to disturbances in urban environments. However, there is limited research on the influence of how urbanization affects bird tolerance towards humans, especially in developing sub-tropical regions such as Nepal, which is undergoing rapid unplanned urbanization. This study identified the flight initiation distance (FID) as a proxy for assessing bird tolerance. We focused on evaluating the human tolerance levels of 33 bird species using their FIDs in urban and rural habitats within Kathmandu Valley, a rapidly urbanizing city in South Asia. We found higher tolerance in urban birds than in their rural conspecifics, which varies mainly with dietary guild and season. The positive impact on FID was associated with time of the day and body size, while a negative association was observed with flock size, mean population density of humans and interaction between body size and elevation. Our study highlights the increased tolerance level of birds in urban areas, probably owing to habituation, and emphasizes the imperative need to investigate the potential adverse effect on urban bird population owing to this increased tolerance level.

Understanding the costs and economic impact of mental disorders in South Asia: A systematic review.

BACKGROUND: Mental disorders remain the most significant contributor to years lived with disability in South Asia, yet governmental health expenditure on mental health in South Asia remains very low with limited strategic policy development. To strengthen the case for action it is important to better understand the profound economic costs associated with poor mental health. METHODS: We conducted a systematic review on the costs of all mental disorders, as well as intentional self-harm and suicide, in the World Bank South Asia Region. Ten global and South Asian databases as well as grey literature sources were searched. RESULTS: 72 studies were identified, including 38 meeting high quality criteria for good reporting of costs. Of these, 27 covered India, five Pakistan, four Nepal and three Bangladesh and Sri Lanka. Most studies focused on depressive disorders (15), psychoses (14) and harmful alcohol use (7); knowledge of economic impacts for other conditions was limited. Profound economic impacts within and beyond health care systems were found. In 15 of 18 studies which included productivity losses to individuals and/or carers, these costs more than outweighed costs of health care. CONCLUSION: Mental disorders represent a considerable economic burden, but existing estimates are conservative as they do not consider long-term impacts or the full range of conditions. Modelling studies could be employed covering longer time periods and more conditions. Clear distinctions should be reported between out-of-pocket and health system costs, as well as between mental health service-specific and physical health-related costs.

Frequency of pharmacogenomic variants affecting safety and efficacy of immunomodulators and biologics in a South Asian population from Sri Lanka.

BACKGROUND: Immunomodulators are important for management of autoimmune diseases and hematological malignancies. Significant inter-individual variation in drug response/reactions exists due to genetic polymorphisms. We describe frequency of identified genetic polymorphisms among Sri Lankans. METHODS: Sri Lankan data were obtained from an anonymized database of 670 participants. Data on variants and global distribution of Minor Allele frequency (MAF) of other populations (South Asian, Ashkenazi-Jewish, East-Asian, European-Finnish, European-non-Finnish, Latino-American, African/African-American) were obtained from pharmGKB online database. RESULTS: SLC19A1 (rs1051266) variant had a MAF (95% CI) of 63.3% (60.7-65.9). Other common variants included FCGR3A (rs396991), MTHFR (rs1801133), ITPA (rs1127354), CYP2C9*3 (rs1057910) and NUD15*3 (rs116855232), with MAFs of 35.3% (32.7-37.9), 12.2% (10.4-13.9), 10.9% (9.2-12.6), 9.8% (8.2-11.4), 8.3% (6.8-9.8) respectively. Less commonly present variants included CYP2C9*2 (rs1799853) (2.5%[1.7-3.4]), TPMT*3C (rs1142345) (1.9%[1.1-2.6]), TPMT*3B (rs1800460) (0.2%[0-0.5]), CYP3A5*6 (rs10264272) (0.2%[0-0.4]) and CYP3A4*18 (rs28371759) (0.1%[0-0.2]). The SLC19A1 (rs1051266), NUD15*3 (rs116855232), CYP2C9*3 (rs1057910), FCGR3A (rs396991), and ITPA (rs1127354) showed significantly higher frequencies in Sri Lankans compared to many other populations, exceptions include FCGR3A in Ashkenazi-Jewish and ITPA in East-Asians. Conversely, MTHFR (rs1801133), TPMT*3B (rs1800460), and CYP2C9*2 (rs1799853) were significantly less prevalent among Sri Lankans than in  many other populations. Sri Lankans exhibited lower prevalence of TPMT*3C (rs1142345) compared to European-non-Finnish, Latino-Americans, and African/African-Americans; CYP3A4*18 (rs28371759) compared to East-Asians; and CYP3A5*6 (rs10264272) compared to African/African-Americans and Latino-Americans. CONCLUSION: Sri Lankans exhibit higher frequencies in variants reducing methotrexate efficacy (SLC19A1), increasing azathioprine myelotoxicity (NUDT15), and lower frequencies in variants linked to increased azathioprine toxicity (TPMT*3B, TPMT*3C), reduced tacrolimus efficacy (CYP3A4*18), and methotrexate toxicity risk (MTHFR). Beneficial variants enhancing rituximab efficacy (FCGR3A) are more prevalent, while those reducing tacrolimus dosage (CYP3A5*6) are less common. This highlights need for targeted medication strategies to improve treatment outcomes.

Establishment of a patient and public involvement and engagement group to support clinical trials in Pakistan: Initial lessons learned.

BACKGROUND: Patient and public involvement and engagement (PPIE) in clinical trials is increasingly recognized as vital for ensuring research relevance and accessibility. Despite its proven benefits, PPIE remains limited, particularly in low- and middle-income countries, and more examples of effective strategies for involvement are needed. This commentary outlines the establishment of a PPIE group for clinical trials in a lower-middle-income country setting with limited research infrastructure. MAIN BODY: We established Pakistan's first ever PPIE group for clinical trials within a new clinical trials unit at Ziauddin University in Karachi. The objectives of our project were focused on group formation, redesign of informed consent documents for trials, and dissemination of trial results to the public. Recruitment strategies involved referrals from clinicians and existing collaborators as well as engagement at public events, distribution of advertising leaflets and social media posts. Ten potential members were selected based on motivation, commitment and ability to contribute critically, with six members continuing their involvement long-term. An existing tool designed to establish the access needs of public partners was adapted to our project to help us document and account for members' expectations and support requirements. The process of using the tool enabled deep engagement, clarified roles, and fostered trust between coordinators and group members. Patient and public members gained confidence about the legitimacy of the project and felt more comfortable participating in the first group meeting. Lessons learned emphasize the importance of wide-ranging engagement efforts and transparent discussions about expectations to build effective collaborative relationships. CONCLUSION: Our experience demonstrates the feasibility of establishing a PPIE group for clinical trials in Pakistan and highlights strong public interest for research involvement. The use of a formal tool to document needs, prior experiences and expectations encouraged relationship-building and helped coordinators make relevant accommodations for members. This account contributes to the growing body of literature on effective PPIE practices, emphasizing the value of tailored support and transparent communication in facilitating meaningful public involvement in clinical trials.

Working together with patients and members of the public has the potential of making clinical trials better, more person-centered and relevant. Unfortunately, partnerships between trial researchers and the public are still uncommon. It is not known what the best ways are to involve the public in clinical trials, especially when it comes to non-Western populations. We set up the first-ever patient and public involvement and engagement group to support clinical trials in Pakistan. In this commentary, we share our initial experiences of successfully establishing the group and the two main lessons we learned. Ten group members were identified by widely advertising our project to doctors, community organizations, patients and their carers at our hospital. Before the first group meeting, two coordinators met with each potential member to discuss and document their interests, expectations and needs. Both researchers and group members felt that these discussions were a good use of their time and helped make the project a success. The first main lesson learned from our experience was that enough time, funding, staff and resources are needed to identify members and build meaningful collaborative partnerships. The second main lesson learned was that honest discussions are needed at the very beginning of a collaboration about expectations. Our experience shows that involving patients and members of the public in clinical trials in Pakistan is possible and we hope it inspires and helps other researchers in their patient and public engagement efforts.

Anthropometric indices in predicting 10-year cardiovascular risk among males and females aged 40-74 years in south and southeast Asia: analysis of 12 WHO STEPS survey data.

Background: The relevance of anthropometric indices in predicting cardiovascular disease (CVD) or CVD risk factors is established across different countries, particularly in the high-income countries. However, past studies severely lacked representation from the south and southeast Asian countries. The main aim of this study was to determine the performance of conventional and new anthropometric indices to best predict 10-year cardiovascular disease (CVD) risk in south Asian and southeast Asian populations. Methods: The present study examined data from 14,532 participants in three south Asian and 13,846 participants (all aged between 40 and 74 years) in six southeast Asian countries, drawn from twelve cross-sectional studies (WHO STEPwise approaches to NCD risk factor surveillance [STEPS] survey data from 2008 to 2019). A Predictive performance of ten anthropometric indices were examined for predicting 10-year CVD risk ≥ 10% (CVD-R ≥ 10%). The 10-year CVD-R ≥ 10% was calculated by utilising the WHO CVD risk non-laboratory-based charts. Receiver operating characteristic (ROC) curve analysis was used to identify the optimal anthropometric index. Findings: Among the ten anthropometric indices, a body shape index (ABSI), body adiposity index (BAI), body roundness index (BRI), hip index (HI), and waist-height ratio (WHtR) performed best in predicting 10-year CVD risk among south Asian males and females. Improved performances were found for ABSI, BRI, conicity index (CI), WHtR, and waist-hip ratio (WHR) for 10-year CVD-R ≥ 10% predictions among southeast Asian males. Contrastingly, among southeast Asian females, ABSI and CI demonstrated optimal performance in predicting 10-year CVD-R ≥ 10%. Interpretation: The performance of anthropometric indices in predicting CVD risk varies across countries. ABSI, BAI, BRI, HI, and WHtR showed better predictions in south Asians, whereas ABSI, BRI, CI, WHtR, and WHR displayed enhanced predictions in southeast Asians. Funding: None.

Temporal Mortality Trends Attributable to Stroke in South Asia: An Age-Period-Cohort Analysis.

South Asia contributes the most to stroke mortality worldwide. This study aimed to determine the long-term trends in stroke mortality across four South Asian countries and its associations with age, period, and birth cohort. In 2019, nearly one million stroke deaths occurred across South Asia, and the associated age-standardized mortality rate (ASMR) was 80.2 per 100,000. Between 1990 and 2019, India had the largest decrease in the ASMR (-35.8%) across the four South Asian countries. While Pakistan had the smallest decrease in the ASMR (-7.6%), an increase was detected among males aged 15 to 34 years and females aged 15 to 19 years. Despite a 22.8% decrease in the ASMR, Bangladesh had the highest ASMR across the four South Asian countries. Nepal reported a witness increase in the stroke ASMR after 2006. Improved period and cohort effects on stroke mortality were generally indicated across the analyzed countries, except for recent-period effects in males from Nepal and cohort effects from those born after the 1970s in Pakistan. Stroke mortality has decreased in the four South Asian countries over the past 30 years, but potentially unfavorable period and cohort effects have emerged in males in Nepal and both sexes in Pakistan. Governmental and societal efforts are needed to maintain decreasing trends in stroke mortality.

Reorienting health systems towards Primary Health Care in South Asia.

This series, "Primary health care in South Asia", is an effort to provide region-specific, evidence-based insights for reorienting health systems towards PHC. Led by regional thinkers, this series draws lessons from five countries in South Asia: Bangladesh, India, Nepal, Pakistan, and Sri Lanka. This is the last paper in the series that outlines points for future action. We call for action in three areas. First, the changing context in the region, with respect to epidemiological shifts, urbanisation, and privatisation, presents an important opportunity to appraise existing policies on PHC and reformulate them to meet the evolving needs of communities. Second, reorienting health systems towards PHC requires concrete efforts on three pillars-integrated services, multi-sectoral collaboration, and community empowerment. This paper collates nine action points that cut across these three pillars. These action points encompass contextualising policies on PHC, scaling up innovations, allocating adequate financial resources, strengthening the governance function of health ministries, establishing meaningful public-private engagements, using digital health tools, reorganising service delivery, enabling effective change-management processes, and encouraging practice-oriented research. Finally, we call for more research-policy-practice networks on PHC in South Asia that can generate evidence, bolster advocacy, and provide spaces for cross-learning.

Strengthening primary health care through community health workers in South Asia.

The growing health challenges in South Asia require further adaptations of community health worker (CHW) programs as a key element of primary health care (PHC). This paper provides a comparative analysis of CHW programs in five countries (Bangladesh, India, Nepal, Pakistan, and Sri Lanka), examines successes and challenges, and suggests reforms to better ensure highly performing CHW programs. To examine CHW programs in the region, we conducted a narrative review of the peer-reviewed and grey literatures, as well as eliciting opinions from experts. Common roles of CHWs include health education, community mobilization, and community-based services, particularly related to reproductive, maternal, neonatal, and child health. Some countries utilize CHWs for non-communicable diseases and other emerging health issues. To maximize the potential contribution of CHWs to achieving Universal Health Coverage, we recommend future research and policy focus on strengthening existing health systems to support the expansion of CHWs roles and better integrating of CHWs into national PHC systems. This is Paper 4 in the Series on Primary Health Care in South Asia, addressing areas that have the potential to revitalize health systems in South Asian countries.

Understanding the spatial patterns of atmospheric ammonia trends in South Asia.

Ammonia (NH3) is the most abundant alkaline gas in the atmosphere, mainly emitted by agricultural activities. NH3 readily reacts with other atmospheric acidic pollutants, such as the oxidation products of sulfur dioxide (SO2) and nitrogen oxides (NOₓ), to create fine particulate matter, which has far-reaching effects on human health and ecosystems. Here, we investigated long-term atmospheric NH3 trends in South Asia (SA) using satellite observations from the Infrared Atmospheric Sounding Interferometer (IASI). We analyzed 15 years (2008-2022) of IASI-NH3 retrievals against climate, biophysical, and chemical variables using an ensemble of multivariate statistical methods to identify the major factors driving the observed patterns in the region. Trend analysis of IASI-NH3 data reveals a significant rise in atmospheric NH3 over 51 % of SA plains, but a downward trend over 31 % of the region. Spatial correlation analysis reveals that biophysical factors, representing cropland expansion and agriculture intensification, have the highest positive correlation over 56 % of SA plains experiencing positive NH3 trends. However, our results reveal that the chemical conversion of NH3 to ammonium compounds, driven by the positive trends in NOₓ and SO2 pollution, is driving the apparently declining trend of NH3 in the other regions. Our results provide important insights into the NH3 trends detected by satellite data and can better inform the policy design aimed at reducing NH3 emissions and improving air quality for developing regions of the world.

Balancing growth and sustainability: COP 28 policy implications of green energy, industrialization, foreign direct investment, and globalization in South Asia.

This research investigates the intricate relationships between economic variables and how they affect South Asian nation's ability to develop sustainably. Given the growing concerns about climate change and global warming brought on by emissions of greenhouse gases, this study looks into the connection between emissions of CO2, green energy, industrialization, foreign direct investment, economic globalization, and financial development from 1995 to 2022. Second-generation panel techniques were employed in this study to look at the relationship between variables because of the potential of residual cross-sectional dependency and heterogeneity. The empirical outcomes display that green energy, economic globalization, and financial development reduce CO2 emissions by 1.839%, 1.223%, and 3.902% respectively. Industrialization and foreign direct investment degrade the environment by 4.302% and 1.893% respectively. A bidirectional causality link between green energy, industrialization, economic globalization, and CO2 emissions was found by Dumitrescu and Hurlin (D-H). Based on our findings, we recommend legislative support for renewable energy, cleaner technologies, and strict environmental regulations, aligning with the Sustainable Development Goals (SDGs). Encouraging FDI, sustainable practices, and financial development can drive economic growth while preserving the environment. As we approach COP28, this holistic approach to sustainable development becomes increasingly vital for South Asian countries to achieve their SDG targets and combat climate change.

A comparative systematic review of risk factors, prevalence, and challenges contributing to non-communicable diseases in South Asia, Africa, and Caribbeans.

BACKGROUND: Non-communicable diseases (NCDs) are a global epidemic challenging global public health authorities while imposing a heavy burden on healthcare systems and economies. AIM: To explore and compare the prevalence of NCDs in South Asia, the Caribbean, and non-sub-Saharan Africa, aiming to identify both commonalities and differences contributing to the NCD epidemic in these areas while investigating potential recommendations addressing the NCD epidemic. METHOD: A comprehensive search of relevant literature was carried out to identify and appraise published articles systematically using the Cochrane Library, Ovid, Google Scholar, PubMed, Science Direct, and Web of Science search engines between 2010 and 2023. A total of 50 articles fell within the inclusion criteria. RESULTS: Numerous geographical variables, such as lifestyle factors, socio-economic issues, social awareness, and the calibre of the local healthcare system, influence both the prevalence and treatment of NCDs. The NCDs contributors in the Caribbean include physical inactivity, poor fruit and vegetable intake, a sedentary lifestyle, and smoking, among others. While for South Asia, these were: insufficient societal awareness of NCDs, poverty, urbanization, industrialization, and inadequate regulation implementation in South Asia. Malnutrition, inactivity, alcohol misuse, lack of medical care, and low budgets are responsible for increasing NCD cases in Africa. CONCLUSION: Premature mortality from NCDs can be avoided using efficient treatments that reduce risk factor exposure for individuals and populations. Proper planning, implementation, monitoring, training, and research on risk factors and challenges of NCDs would significantly combat the situation in these regions.

Dataset on the status of crop diversification in the Eastern Indo Gangetic Plains of South Asia.

South Asia's Eastern Indo-Gangetic Plains (EIGP) is home to approximately 450 million people. This region is characterized by the highest global concentration of rural poverty and a predominant reliance on agriculture for nutritional sustenance and economic livelihoods. Agriculture in the EIGP is highly cereal-centric, making crop diversification indispensable for its development. This data article is part of the research conducted by an interdisciplinary team of researchers analysing the status and determinants of crop diversification in South Asia's EIGP. The data presented here were collected from 1,400 farm households across 72 communities in eight locations within the EIGP of India, Nepal, and Bangladesh during the year 2023. The research employed a simple random sampling method for empirical data collection. The primary agricultural decision-makers were given a tailored questionnaire comprising seven modules. These modules sought comprehensive data on livelihood practices, changes in agriculture, aspirations, diet, food security, mechanization, demographics, and asset ownership. The questionnaire was translated from English into Nepali and Bangla to facilitate a thorough understanding of the farmers' livelihoods in the study areas. The survey successfully ended with 1400 properly filled and captured questionnaires, which was quite representative. The cross-sectional data presented here describe location-specific farm-level crop distribution, enabling the analysis of geographic variations in crop diversification. The generation of this dataset addresses a significant gap in the availability of information on the current state of crop diversification in the EIGP, offering a foundational baseline for future research and interventions by regional governments and development partners. We employed the Herfindahl-Hirschman Index (HHI) to calculate crop diversification and a Tobit Regression Model to identify the region-specific determinants of crop diversification. The dataset is hereby made available as it is considered vital for regional policy and practical recommendations.

Improved food habits and anthropometry among primary school children following a novel healthy eating programme.

OBJECTIVE: Assess longer-term changes in food habits and anthropometry among Grades 1-2 primary school students from four public schools in Colombo, Sri Lanka, following a 3-week programme including a classroom-based motivational storybook discussion and self-monitoring food diary (FD). METHODS: This follow-up study assessed changes from baseline (pre-intervention) BMI z-scores and food habits (increased healthy food-item consumption/decreased unhealthy food-item consumption reflected by an increase in FD score) and parental perceptions (anonymous questionnaires) among 863 students (aged 6-8 years), between 9 and 12 months after completing the programme (November 2019-February 2020). RESULTS: Food habits showed sustained improvement from baseline mean FD score (baseline vs. follow-up: 51 ± 23% vs. 67 ± 22%, p < 0.001), with children from all BMI subgroups (underweight [UW], normal weight [NW], overweight [OW] and obesity [OB]) showing a significant increase in FD scores (ranging from 14.1% to 17.2%, p < 0.001). BMI z-scores increased in children living with UW (-2.85 to -2.21, p < 0.00) and NW (-0.70 to -0.57, p < 0.001), but did not change in children with OW (+1.5 to +1.49, p = 0.83) and OB (+2.85 to +2.21, p = 0.19). Most parents (n = 497, 97.8%) reported satisfaction with programme outcomes. CONCLUSION: This programme led to sustained improvement in food habits among young primary school children from all BMI categories, increase in BMI towards the median among children living with UW and NW, and stabilization of BMI in children with OW and OB, suggesting it as a useful tool for improving nutritional status of young children in low- and middle-income countries (LMIC) facing the double burden of under- and overnutrition.

Health Data Sciences and Cardiovascular Diseases in South Asia: Innovations and Challenges in Digital Health.

PURPOSE OF REVIEW: Health data sciences can help mitigate high burden of cardiovascular disease (CVD) management in South Asia by increasing availability and affordability of healthcare services. This review explores the current landscape, challenges, and strategies for leveraging digital health technologies to improve CVD outcomes in the region. RECENT FINDINGS: Several South Asian countries are implementing national digital health strategies that aim to provide unique health account numbers for patients, creating longitudinal digital health records while others aim to digitize healthcare services and improve health outcomes. Significant challenges impede progress, including lack of interoperability, inadequate training of healthcare workers, cultural barriers, and data privacy concerns. Leveraging digital health for CVD management involves using big data for early detection, employing artificial intelligence for diagnostics, and integrating multiomics data for health insights. Addressing these challenges through policy frameworks, capacity building, and international cooperation is crucial for improving CVD outcomes in region.

A Systematic Review of the Effect of Gene-Lifestyle Interactions on Metabolic-Disease-Related Traits in South Asian Populations.

CONTEXT: Recent data from the South Asian subregion have raised concern about the dramatic increase in the prevalence of metabolic diseases, which are influenced by genetic and lifestyle factors. OBJECTIVE: The aim of this systematic review was to summarize the contemporary evidence for the effect of gene-lifestyle interactions on metabolic outcomes in this population. DATA SOURCES: PubMed, Web of Science, and SCOPUS databases were searched up until March 2023 for observational and intervention studies investigating the interaction between genetic variants and lifestyle factors such as diet and physical activity on obesity and type 2 diabetes traits. DATA EXTRACTION: Of the 14 783 publications extracted, 15 were deemed eligible for inclusion in this study. Data extraction was carried out independently by 3 investigators. The quality of the included studies was assessed using the Appraisal Tool for Cross-Sectional Studies (AXIS), the Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I), and the methodological quality score for nutrigenetics studies. DATA ANALYSIS: Using a narrative synthesis approach, the findings were presented in textual and tabular format. Together, studies from India (n = 8), Pakistan (n = 3), Sri Lanka (n = 1), and the South Asian diaspora in Singapore and Canada (n = 3) reported 543 gene-lifestyle interactions, of which 132 (∼24%) were statistically significant. These results were related to the effects of the interaction of genetic factors with physical inactivity, poor sleep habits, smoking, and dietary intake of carbohydrates, protein, and fat on the risk of metabolic disease in this population. CONCLUSIONS: The findings of this systematic review provide evidence of gene-lifestyle interactions impacting metabolic traits within the South Asian population. However, the lack of replication and correction for multiple testing and the small sample size of the included studies may limit the conclusiveness of the evidence. Note, this paper is part of the Nutrition Reviews Special Collection on Precision Nutrition. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration No. CRD42023402408.

Divergence and serial colonization shape genetic variation and define conservation units in Asian elephants.

Asian elephants (Elephas maximus) are the largest extant terrestrial megaherbivores native to Asia, with 60% of their wild population found in India. Despite ecological and cultural importance, their population genetic structure and diversity, demographic history, and ensuing implications for management/conservation remain understudied. We analyzed 34 whole genomes (between 11× and 32×) from most known elephant landscapes in India and identified five management/conservation units corresponding to elephants in Northern (Northwestern/Northeastern), Central, and three in Southern India. Our data reveal signatures of divergence and serial colonization and a potential dilution of genetic diversity from north to south of India. The northern populations diverged from others more than 70,000 years ago, have higher genetic diversity, and have low inbreeding (pi = 0.0016 ± 0.0001; FROH > 1 MB = 0.09 ± 0.03). Two of three populations in Southern India have low diversity and are inbred, with very low effective population sizes compared with census sizes (pi = 0.0014 ± 0.00009 and 0.0015 ± 0.0001; FROH > 1 MB = 0.25 ± 0.09 and 0.17 ± 0.02). Analyses of genetic load reveal the purging of potentially high-effect insertion/deletion (indel) deleterious alleles in the southern populations and a decreasing number of deleterious alleles from north to south in India. However, despite dilution and purging for the damaging mutation load in Southern India, the load that remains is homozygous. High homozygosity of deleterious alleles, coupled with low neutral genetic diversity, make southernmost populations high priority for conservation attention. Most surprisingly, our study suggests that patterns of genetic diversity and genetic load can correspond to genomic signatures of serial founding events, even in large, highly mobile, endangered mammals.

Trends of endometrial cancer incidence in Sri Lanka from 2011 to 2020: An analysis of annual national cancer incidence data reports.

Introduction: The incidence of endometrial cancer in low-income countries is rising at a rapid rate. This could be due to changes in risk factors and socio-economic transitions occurring in developing countries. The main aim of this study was to assess the changes in endometrial cancer incidence in Sri Lanka. Materials and Methods: Incidence data for uterine corpus cancer and endometrial cancer between 2011 and 2020 were extracted from the National Cancer Register of Sri Lanka. This included the crude rate, age standardised incidence rate, and age-specific incidence. Joinpoint trend analysis software was used to analyse the temporal pattern of incidence. The estimated annual percentage change of incidence (EAPC) was calculated. Results: A total of 8332 patients with uterine corpus cancer were reported with the highest incidence in the 60-70-year-old age group. The EAPC of uterine corpus cancer was 9.26%, while it was 8.26% for endometrial cancer. The highest rise of age-specific incidence was observed in the 70 years plus age group (EAPC 13.3968%, 95% confidence interval (CI): 9.6916-17.1994). Conclusion: There is a clear rise in endometrial and uterine cancer incidence in Sri Lanka. While part of this could be due to better reporting of new cases, a true increase in incidence should have occurred due to different rates of EAPC among age categories. Studies to evaluate the factors leading to the rising incidence of endometrial cancer are recommended.
