RESUMO
The corpus callosum (CC), the largest commissure of the brain, connects the two cerebral hemispheres and lies at the bottom of the longitudinal fissure. The antero-posterior diameter of the CC was larger in males than in females, but this difference was not significant. Again, the length of CC increased with age and there was also a positive significant correlation between the antero-posterior diameters of the CC with the antero-posterior diameter of the brain. This cross sectional descriptive study was performed into four categories: Group A (20-29 years), Group B (30-39 years), Group C (40-49 years) and Group D (50 years and above). The specimens were collected from morgue in the department of Forensic Medicine, Mymensingh Medical College, Bangladesh by purposive sampling technique Octy 2016 to Octy 2017. The antero-posterior diameter of CC was measured by using thread. The mean maximum antero-posterior diameter of corpus callosum was 8.25 cm in group D and minimum was 7.92 cm in Group A. When the diameter was compared between sexes in different age groups, it was significant in Group D and moderately significant in Group C. There was a positive correlation between antero-posterior diameter of corpus callosum and age of individual and it was statistically not significant. For statistical analysis, differences between age and sex groups were analyzed by using students unpaired 't' test. The present study will help to increase the information pool on the antero-posterior diameter of CC of Bangladeshi people and thus will minimize the dependency on foreign standards and also have diagnostic importance for the neurosurgeons and radiologists for clinical investigation and surgery.

The vermiform appendix is a tubular, blind-ended secondary lymphoid organ located near the caecum, often referred to as the "tonsil of the abdomen" due to the abundance of lymphoid follicles in its histology. The presence of germinal centers, which are indicators of lymphatic tissue response to antigens and subsequent antibody production, helps assess the immune status of individuals. By counting these germinal centers, researchers can evaluate the immune status of the Bangladeshi population across different age and sex groups. This study was conducted at Mymensingh Medical College, approximately 120 km north of Dhaka, the capital of Bangladesh. Samples were randomly selected from the local population between 2016 and 2017, including 40 vermiform appendices from various age groups: Group A (up to 20 years), Group B (21-40 years), Group C (41-60 years) and Group D (over 60 years). After obtaining ethical approval, the germinal centers, identified by their lighter staining in the center of lymphoid follicles, were counted under a microscope (X4 objective, X10 eyepiece). The average number of germinal centers per age group was then calculated. The study found that the mean±SD number of germinal centers was 3.20±1.66, 2.40±0.66, 1.50±1.11 and 0.30±0.45 across the advancing age groups. The mean differences of number of germinal center between A&B, B&C were statistically non significant at p= or >0.05 level, difference between group C&D, A&C was statistically significant at p<0.05 level and differences between group B&D, A&D were statistically highly significant at p<0.001 level. Mean±SD number of germinal center of vermiform appendix in male was higher (3.60±1.02, 2.42±0.49, 1.50±1.26 and 0.33±0.47 in Group A, B, C and D respectively) than in female (2.80±1.17, 2.33±0.94, 1.30±0.87 and 0.25±0.43 in Group A, B, C and D respectively) but mean difference between sexes in the different groups was statistically non significant at p=or >0.05 level. Overall, the study observed a gradual decline in the number of germinal centers with increasing age.

Searching for missing or wanted people is a crucial task in our society. Previous work on prospective person memory (PPM) has demonstrated that performance on this type of search task is worse relative to standard prospective memory tasks. Importantly, this process may be further affected by the race of the missing person, yet this has never been tested in laboratory settings. To test the effects of race on PPM, a convenience sample consisting primarily of self-identified Caucasian participants was asked to search for either a Caucasian or an Indian target person while judging the orientation of different Caucasian and Indian faces. Although the tasks were otherwise identical, 89% of Caucasian PPM targets were found while only 53% of Indian targets were found. Furthermore, relative to a control group with no PPM requirements, participants were slower and more error-prone when judging Indian faces relative to White faces, particularly if they were searching for an Indian face. We interpret these results as revealing other-race effects in prospective person memory, highlighting race as a critical factor for finding missing people. Importantly, this also emphasizes the need for real-world search efforts to factor in difficulty differences when people monitor for missing/wanted people from their own or different racial backgrounds. For example, media coverage of missing persons cases could perhaps be distributed more equitably by considering whether the missing person is from a racial minority in that region.

BACKGROUND: COVID-19 Ethnic Inequalities in Mental health and Multimorbidities (COVEIMM) is a mixed methods study to explore whether COVID-19 exacerbated ethnic health inequalities in adults with serious mental and physical health conditions. We analysed data from electronic health records for England and conducted interviews in Birmingham and Solihull, Manchester, and South London. Sites were selected because they were pilot sites for the Patient and Carer Race Equality Framework being introduced by NHS England to tackle race inequalities in mental health. Prior to the pandemic people in England with severe mental illnesses (SMIs) faced an 11-17-year reduction in life expectancy, mostly due to preventable, long-term, physical health conditions. During the pandemic there was a marked increase in deaths of those living with an SMI. AIMS: This qualitative interview study aimed to understand the reasons underlying ethnic inequalities in mortality and service use during the COVID-19 pandemic for adult service users and carers of Black African, Black Caribbean, Indian, Pakistani, and Bangladeshi backgrounds living with serious multiple long-term mental and physical health conditions. METHODS: We took a participatory action research approach and qualitative interviews undertaken by experts-by-experience and university researchers Participants were purposively sampled by ethnicity, diagnoses, and comorbidities across three geographically distinct sites in England. Transcriptions were coded inductively and deductively and analysed thematically. RESULTS: Findings indicated multiple points along primary and secondary health pathways for mental and physical health that have the potential to exacerbate the unjust gap in mortality that exists for Black and Asian people with SMIs. Issues such as timely access to care (face-to-face and remote), being treated in a culturally appropriate manner with empathy, dignity and respect, and being able to use services without experiencing undue force, racism or other forms of intersectional discrimination were important themes arising from interviews. CONCLUSION: These poor experiences create systemic and enduring healthcare harms for racialised groups with SMIs that need to be addressed. Our findings suggest a need to address these, not only in mental health providers, but across the whole health and care system and a need to ensure more equitable healthcare partnerships with service users, carers, and communities from racialised backgrounds who are often excluded.

Objectives: To examine the relationship between acculturation, cultural perceptions surrounding mental health (MH) burden and utilization of MH services among South Asian (SA) adults in the United States. Design: Cross-sectional study. Setting: Online survey. Participants: Four hundred five SA adults (≥18 years old) residing in the United States. Methods: Cross-sectional study of acculturation, attitudes toward MH burden, and MH service utilization was conducted via online survey. Multivariate logistic regression models were employed to understand how these factors were associated with MH service utilization. Main outcome measure: Utilization of MH services. Results: Among the 405 participants, 49.0% identified as immigrants (75.1% Indian, 8% Bangladeshi, 5.5% Pakistani, and 3.8% from other SA countries). Current utilization of MH services was associated with comfort conversing in English (odds ration [OR]=5.99; 95% confidence interval [CI]=1.63, 27.02), having English-speaking peers (OR=3.80; 95% CI=1.12, 12.93), and having family (OR=2.37; 95% CI=1.21, 4.64) and peers (OR=5.64; 95% CI=1.71, 18.66) who used MH services. Participants with mostly SA peers (OR=0.48; 95% CI=0.23, 0.97) reported lower lifetime MH service utilization, and those with positive perceptions about MH burden reported higher lifetime utilization (OR=1.04; 95% CI=1.01, 1.09). Conclusions: Comfort expressing emotions in English, knowledge of family/peer MH service use, and type of social connections were associated with MH service utilization among SA immigrants. Interventions should aim to increase SA languages in which MH services are offered and to engage with SA communities to increase acceptance of MH service utilization.

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.

There is an urgent need to develop sustainable and impactful interventions to mitigate the high risk of diet-related non-communicable diseases (diet-NCDs) in South Asians living in high-income countries. The current study using a co-design methodology aimed to identify community-led intervention components (solutions) to address barriers and enablers of disease-promoting dietary and physical activity behaviours in New Zealand South Asians. Data were collected from South Asian immigrants aged 25-59 years via three focus group discussions (n = 21) and 10 telephone or face-to-face interviews between 2018 and 2019. The thematic analysis resulted in identifying 22 barrier and enabler codes and 12 solution codes which were summarised under five themes. The key solutions (intervention components) to mitigate the identified target behaviours were providing recipes for using local vegetables in South Asian cuisine, information on the nutritional quality of frozen vegetables and canned lentils, simple home gardening techniques, the saturated fat content of dairy foods, interpreting nutrition labels, optimal portion sizes of foods, and framing low-fat messages positively. Similarly, group-based activities with peer support such as walking, cultural dancing and community sports like cricket, football, and tennis were the identified solutions to increase physical activity levels. The identified solutions for health promoting dietary habits and physical activity levels could be part of any targeted multicomponent health promoting programme to reduce the risk of diet-NCDs in South Asian immigrants.

BACKGROUND: This study aimed to test the efficacy of patient-centered self-management intervention (PACE-SMI) to improve HbA1c, self-efficacy, and self-care behaviors in adults with type 2 diabetes mellitus (T2DM). METHODS: In this multicenter, parallel two-arm randomized controlled trial, 612 adults with T2DM and HbA1c ≥ 7% were enrolled and assigned to the control group (n = 310) and the intervention group (n = 302) using stratified permuted block randomization. The control group received usual care, whereas the intervention group received usual care plus nurse-led, theory-driven, culturally tailored PACE-SMI, comprising eight weekly sessions of individualized education, counseling, behavioral training, and home visit. Outcomes were assessed at baseline, postintervention, and 3 months follow-up. RESULTS: Data at 3 months were provided by 583 participants (control: n = 295, intervention: n = 288). Per-protocol analysis showed that the intervention group had a lower mean HbA1c (8.49% [standard deviation (SD), 1.58]) than the control group (8.74% [SD, 1.62]), with small yet statistically significant mean difference of 0.25% (95% confidence interval [CI], -0.01 to 0.51; Cohen's d = 0.16; p = 0.03). Self-efficacy and self-care behaviors significantly improved in the intervention group (116.89 [SD, 25.50] and 70.01 [SD, 17.97]) compared to the control group (75.43 [SD, 18.99] and 51.54 [SD, 12.04]), with mean differences of 41.48 (95% CI, 37.83-45.13; Cohen's d = 1.84; p < 0.0001) and 18.56 (95% CI, 16.08-21.04; Cohen's d = 1.22; p < 0.0001), respectively. Linear regression analysis indicated the effect of PACE-SMI on HbA1c was significantly mediated by improvements in self-efficacy and self-care behaviors (R2 = 0.232, p < 0.001). CONCLUSION: PACE-SMI led to modest but significant improvement in HbA1c and substantial enhancements in self-efficacy and self-care behaviors in adults with T2DM.

Use of natural green spaces (NGS) is associated with improved psychological well-being (PWB). Ethnic minorities, particularly South Asian (SA) communities in the UK, face unequal access to NGS and experience a greater prevalence of health challenges than the general population. Improving access to green space can contribute to addressing current health inequalities. Following PRISMA guidelines, this systematic literature review aimed to synthesise existing research on NGS access barriers experienced by SAs and associations between NGS use and PWB. A comprehensive search was conducted through SAGE, Science Direct, and SCOPUS in August 2022; we included qualitative, quantitative and mixed-methods studies with findings on NGS access and/or associations between NGS use and PWB for SAs in the UK. We employed deductive thematic analysis to explore inhibitors and enablers of access which were then conceptualised through a multidimensional framework. Associations between NGS and PWB were coded inductively and mapped separately. This review is registered on PROSPERO: CRD42022353711. Twenty-six studies were included in the review which varied substantially in their aims, methods, context, and participants. Included studies on NGS grouped SAs within broader demographic categories such as minority ethnic communities or Muslims. Our findings indicate that SAs are disadvantaged in their access to NGS due to numerous intersecting factors including unequal distribution, inadequate transport, racialisation of NGS, and safety concerns. Whilst these findings generally aligned with broader literature on NGS access, certain access barriers and enablers are particularly significant to SA communities. We also identified several dimensions of PWB that are enhanced for SAs through interacting with NGS including overall mental health outcomes, physical wellbeing, and social relatedness. This review highlights opportunities to improve access to NGS and thereby enhance PWB outcomes for SA people. It also identifies the lack of primary research exploring NGS access and PWB associations for SA communities, specifically in rural contexts.

BACKGROUND: Cytoplasmic T Lymphocyte Antigen - 4 (CTLA-4) gene encodes an immunoregulatory receptor expressed on surface of activated T-cells to mediate peripheral tolerance against self-antigen. It suppresses auto-reactive T-cell proliferation either by inactivation or apoptosis of T-cells. The CTLA-4 mRNA undergoes alternative splicing to synthesize a native soluble form of CTLA-4 (sCTLA-4) protein, which lacks exon 3 that encodes for transmembrane region. As a result, sCTLA-4 circulates as a soluble serum protein and acts as an immunoregulator molecule to maintain homeostasis in the blood. MATERIALS AND RESULTS: Techniques coupled with quantitative Polymerase Chain Reaction (qPCR) and High-Resolution Melting Analysis (HRMA) were used to screen CTLA-4 3'Untranslated Region (UTR) CT60 (A/G) rs3087243 Single Nucleotide Polymorphism (SNP) and their association with Rheumatoid Arthritis (RA) in the Indian population. In addition, we also evaluated the concentration of sCTLA-4 serum protein in RA patients carrying rs3087243 SNP with different genotypes (A/A, G/A, and G/G). Statistical analysis of Odds Ratio (OR), Confidence Interval (C.I), and Relative Risk (RR) have shown that frequency of CTLA-4 rs3087243 SNP G/G genotype was significantly associated with RA in the Indian population (OR 1.7140; CI = 1.0765 to 2.7290; RR = 1.5434; p = 0.0232). The sCTLA-4 concentration was also significantly lower in RA patients carrying rs3087243 SNP G/G genotype than control group (p < 0.001). CONCLUSION: Co-inheritance of CTLA-4 signal peptide and 3'UTR SNPs may activate RAPP pathway. Downregulation of CTLA-4 and sCTLA-4 serum protein by rs3087243 SNP can increase the hyperactivation of T-cells, which causes RA.

BACKGROUND: The gut microbiome is thought to play an important role in the development of colorectal cancer (CRC). However, as the gut microbiome varies widely based on diet, we sought to investigate the gut microbiome changes in patients with CRC in a South Asian population. METHODS: The gut microbiome was assessed by 16s metagenomic sequencing targeting the V4 hypervariable region of the bacterial 16S rRNA in stool samples (n = 112) and colonic tissue (n = 36) in 112 individuals. The cohort comprised of individuals with CRC (n = 24), premalignant lesions (n = 10), healthy individuals (n = 50) and in those with diabetes (n = 28). RESULTS: Overall, the relative abundances of genus Fusobacterium (p < 0.001), Acinetobacter (p < 0.001), Escherichia-Shigella (p < 0.05) were significantly higher in gut tissue, while Romboutsia (p < 0.01) and Prevotella (p < 0.05) were significantly higher in stool samples. Bacteroides and Fusobacterium were the most abundant genera found in stool samples in patients with CRC. Patients with pre-malignant lesions had significantly high abundances of Christensenellaceae, Enterobacteriaceae, Mollicutes and Ruminococcaceae (p < 0.001) compared to patients with CRC, and healthy individuals. Romboutsia was significantly more abundant (p < 0.01) in stool samples in healthy individuals compared to those with CRC and diabetes. CONCLUSION: Despite marked differences in the Sri Lankan diet compared to the typical Western diet, Bacteroides and Fusobacterium species were the most abundant in those with CRC, with Prevotella species, being most abundant in many individuals. We believe these results pave the way for possible dietary interventions for prevention of CRC in the South Asian population.

The genetic factors of stroke in South Asians are largely unexplored. Exome-wide sequencing and association analysis (ExWAS) in 75 K Pakistanis identified NM_000435.3(NOTCH3):c.3691 C > T, encoding the missense amino acid substitution p.Arg1231Cys, enriched in South Asians (alternate allele frequency = 0.58% compared to 0.019% in Western Europeans), and associated with subcortical hemorrhagic stroke [odds ratio (OR) = 3.39, 95% confidence interval (CI) = [2.26, 5.10], p = 3.87 × 10-9), and all strokes (OR [CI] = 2.30 [1.77, 3.01], p = 7.79 × 10-10). NOTCH3 p.Arg231Cys was strongly associated with white matter hyperintensity on MRI in United Kingdom Biobank (UKB) participants (effect [95% CI] in SD units = 1.1 [0.61, 1.5], p = 3.0 × 10-6). The variant is attributable for approximately 2.0% of hemorrhagic strokes and 1.1% of all strokes in South Asians. These findings highlight the value of diversity in genetic studies and have major implications for genomic medicine and therapeutic development in South Asian populations.

Cocoa flavan-3-ols affect endothelium-dependent responses in resistance vessels and microcirculation has received little attention. We tested the effects of dark chocolate consumption (396 mg total flavanols/day for 3 days) in two Groups of 10 men (18-25 years; non-smokers) each comprising equal numbers of White European (WE) and South Asian (SA) ethnicity. In Group 1, dark chocolate did not affect reactive hyperaemia in forearm muscle, but augmented muscle dilatation evoked by acute mental stress, and reactive hyperaemia and acetylcholine (ACh)-evoked dilatation in cutaneous microcirculation. Conversely, in Group 2, chocolate did not affect cutaneous reactive hyperaemia or ACh-evoked dilatation, but these responses were blunted in Group 1 relative to Group 2. Further, when Groups 1 and 2 were combined, responses were blunted in SAs relative to WEs, augmented by chocolate in SAs only. In Group 2 individuals whose ACh-evoked dilatation was attenuated by nitric oxide synthase (NOS) inhibition, ACh-evoked dilatation was not altered after chocolate, but the attenuating effect of NOS inhibition was lost. Conversely, in Group 2 individuals whose ACh-evoked dilatation was enhanced by NOS inhibition, ACh-evoked dilatation was also augmented by chocolate. We propose that in resistance and microvessels of young men, cocoa flavan-3-ols preferentially augment endothelium-dependent dilator responses whose responses are depressed by familial and lifestyle factors more prevalent in SAs than Wes. Flavan-3-ols may facilitate the NOS pathway but also influence other endothelium-dependent dilators.

Gastric cancer (GC) prevalence is very high in the Asian population. Oncogenic viruses play a crucial role in the progression of different types of cancers. Through reanalysis of clinical RNA-seq data sets derived from Asian GC patients, this study identified the presence of human cytomegalovirus (HCMV) in Asian GC tumors, next to the well-studied association of EBV. Clinical recruitment of the Indian GC cohort and screening for HCMV presence identified a 14.28% occurrence, similar to that observed in the bioinformatics analysis. A combinatorial approach of rank-based meta-analysis and ranking of groups based on an expectation-maximization algorithm identified that the upregulated LINC02864 and MAGEA10 correlated with poor survival of GC patients and downregulated tumor suppressor genes enriching for gastric acid secretion pathway to be associated with HCMV-positive GC patients, revealing the progressive role of HCMV infection in GC. Genes that discriminate between different stages of GC were identified through feature selection implemented in a machine-learning approach. LTF and KLK10 expressions were found to be specifically dysregulated by HCMV and can also indicate the GC stages. The results of this study will guide future studies to identify the functional role of these genes in the HCMV-associated GC.IMPORTANCENearly 75% of gastric cancer (GC) cases reported globally are from the Asian population. Most existing public databases, such as TCGA, comprise only a fractional portion of data derived from Asian ancestry. This study identified EBV and human cytomegalovirus (HCMV)'s higher detection in GC patients. The presence and role of EBV associated with GC are well-known, and the observation of HCMV prompted us to validate the findings in a small cohort of 40 Indian GC patients. We observed a 14.28% occurrence of HCMV in the Indian cohort, similar to that observed from next-generation sequencing. A combinatorial approach of rank-based meta-analysis and ranking of groups based on an expectation-maximization algorithm identified that the upregulated LINC02864 and MAGEA10 correlated with poor survival of GC patients and downregulated tumor suppressor genes enriching for gastric acid secretion pathway to be associated with HCMV-positive GC patients, revealing the progressive role of HCMV infection in GC.

INTRODUCTION: Since 2009, nurses have relocated to Japan from Indonesia, the Philippines, and Vietnam under the auspices of the Economic Partnership Agreement (EPA). We asked why some migrant nurses remain in Japan whereas others leave. METHOD: We applied the methodology of Constructivist Grounded Theory. All participants were internationally educated nurses (IENs) currently or formerly working in Japan after passing the National Nursing Examination. RESULTS: Difficulty in mastering the Japanese language was established as one of the main themes. Initial coding elicited two explanatory sub-categories: lack of confidence in communication and effects of language difficulty on workplace relationships. One explains how practical experience in the workplace affected nurses' confidence in communication. The other explains how levels of Japanese language attainment shaped relationships with colleagues. DISCUSSION: These findings suggest a need to regulate the working conditions of foreign nurses, and a need for training schemes to optimize IEN retention.

BACKGROUND: Individuals of South Asian origin have a greater risk of cardiovascular disease after gestational diabetes mellitus (GDM) than European individuals. B-type natriuretic peptide (BNP) and the amino-terminal fragment of its prohormone (NT-proBNP) are commonly used for heart failure screening and diagnosis, but biologically BNP exerts several beneficial cardiovascular effects primarily by counteracting the renin-angiotensin-aldosterone-system. We asked whether ethnic differences in circulating NT-proBNP levels could be explained by the differences in cardiometabolic and inflammatory risk markers? METHODS: We examined 162 South Asian and 107 Nordic women in Norway 1-3 years after GDM with a clinical examination, fasting blood samples and an oral glucose tolerance test. We measured the levels of NT-proBNP, high-sensitivity cardiac troponin T, high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), leptin, adiponectin and markers of insulin sensitivity, such as the Matsuda insulin sensitivity index (ISI). Finally, we tried to identify which independent covariate best mediated the ethnic differences in NT-proBNP. RESULTS: The mean (SD) age was 35.3 (4.5) years, BMI 29.1 (6.0) kg/m2, waist-height ratio 0.60 (0.08) and 164 women (61%) had prediabetes/diabetes. Notably, South Asian women had lower levels of NT-proBNP than Nordic women in both the normoglycemic and prediabetes/diabetes groups (median (IQR) 26 (15-38) vs. 42 (22-66) ng/L, p < 0.001). Higher NT-proBNP levels were associated with greater insulin sensitivity in both South Asian and Nordic women (p = 0.005 and p < 0.001). South Asian women had higher levels of hsCRP (median (IQR) 2.2 (1.1-4.4) vs. 1.2 (0.3-4.2) mg/L), IL-6 (2.3 (1.5-3.2) vs. 1.5 (1.5-2.5) pg/mL), leptin (1647 (1176-2480) vs. 1223 (876-2313) pmol/L), and lower adiponectin levels (7.2 (5.3-9.3) vs. 10.0 (7.2-13.5) mg/L) and Matsuda ISI (2.4 (1.7-3.7) vs. 4.2 (2.9-6.1), pall<0.01) than Nordic women. Even after adjusting for these differences, higher NT-proBNP levels remained associated with insulin sensitivity (22% higher NT-proBNP per SD Matsuda ISI, p = 0.015). Insulin sensitivity and adiponectin mediated 53% and 41% of the ethnic difference in NT-proBNP. CONCLUSIONS: NT-proBNP levels are lower in South Asian than in Nordic women after GDM. Lower NT-proBNP levels correlate with impaired insulin sensitivity. Lower NT-proBNP levels in South Asian women could, therefore, be attributed to impaired insulin sensitivity rather than total body fat.

INTRODUCTION: People with diabetes are at risk of developing chronic kidney disease. However, limited data are available to quantify their risk of kidney function decline in South Asia. This study evaluates the rate and predictors of kidney function decline among people with type 2 diabetes in South Asia. RESEARCH DESIGN AND METHODS: We analyzed data from the Centre for Cardiometabolic Risk Reduction in South Asia (CARRS) Trial to quantify the rate of decline in estimated glomerular filtration rate (eGFR) in people with type 2 diabetes (n=1146) over 2.5 years of follow-up. The CARRS Trial evaluated a multicomponent intervention of decision-supported electronic health records and non-physician care coordinator to improve diabetes management at 10 diabetes clinics in India and Pakistan. We used linear mixed models to estimate eGFR slope among all participants and tested the association of eGFR slope with demographic, disease-related, and self-care parameters, accounting for randomization and site. RESULTS: The mean age of participants was 54.2 years, with a median duration of diabetes of 7.0 years (IQR: 3.0 - 12.0) and median CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) eGFR of 83.6 (IQR: 67.7 to 97.9) mL/min/1.73 m2. The overall mean eGFR slope was -1.33/mL/min/1.73 m2/year. There were no differences in the eGFR slope by treatment assignment to intervention versus usual care. In the adjusted regression model, pre-existing diabetic retinopathy (slope difference: -2.11; 95% CI: -3.45 to -0.77), previous cardiovascular disease (-1.93; 95% CI: -3.45 to -0.40), and statins use (-0.87; 95% CI: -1.65 to -0.10) were associated with faster eGFR decline. CONCLUSIONS: People with diabetes receiving care at urban diabetes clinics in South Asia experienced annual eGFR decline at two times higher rate than that reported from other contemporary international diabetes cohorts. Risk factors for faster decline were similar to those previously established, and thus care delivery models must put an additional emphasis on kidney protective therapies among subgroups with microvascular and macrovascular diabetes complications.
