With its well-known social networking and strong kinship, evidence of social support may be a potential of low-cost approach for T2DM self- management. Social support is quite important for T2DM prevention and control but such evidence in Thai setting is still limited. Therefore, we aimed to study social support and associated determinants for T2DM patients compared to non-diabetes people.Methods: An observational study with a case–control study design was conducted in Chiang Mai, Thailand, in 2019– 2020. Using inclusion and exclusion criteria, a total of 300 participants: 150 cases, 150 controls were recruited. Participants were selected based on outcome status of having “T2DM”. Cases were defined as newly diagnosed (diagnosis of T2DM within 6 months) adult Thai residents and community controls were non-diabetes participants from the same residential area of cases. Data were analyzed by STATA 17. Descriptive analysis compared the characteristics between case and control group. The relation between social support and T2DM was investigated using multivariable Robust regression analysis.Results: About 96.7% of T2DM patients had good social support. T2DM had a significant association with social support in all models defined by potential confounders. Social support was significantly positively associated with having family mealtimes in model 2 and model 3 and increasing age in model 2. BMI and T2DM family history had significant negative association in model 2 and model 3.Conclusion: Social support of Thai T2DM patients is higher than control group. It can either be originated from a newly acquired peer groups network or from the positive social support by family. Future research should focus on behavioral intervention including family and peers to help them understand their role in life-style modification and management of such a prevalent chronic disease.Keywords: diabetes, family, global health, NCDs, social support, Thailand

Background: Postpartum depression (PPD) is non-psychotic depressive illness after childbirth, and PPD affects the health and social status of mothers and their children. This study aims to identify the prevalence of suspected PPD and associated factors among women in Yangon, Myanmar. Methods: This is a cross-sectional study of 552 women at 6–8 weeks postpartum who visited at North Okkalapa General and Teaching Hospital for postnatal care from September to October 2022. Socio-demographic factors, obstetric and infant factors, family support, and medical history were collected using a structured questionnaire. Myanmar version of the Edinburgh Postnatal Depression Scale (EPDS) was used for screening PPD, and all women were divided into suspected PPD (EPDS ≥10) and non-suspected PPD (EPDS

Conclusion: There was no significant association between VEGF +936C/T polymorphism (rs3025039) and preeclampsia among Myanmar pregnant women. However, the findings of this study highlighted that individuals carrying either the CT genotype or the T allele are at a heightened risk of developing preeclampsia. Furthermore, it suggests a potential impact of the gene on the occurrence of preeclampsia, yet the data lacks sufficient evidence to establish statistical significance.

A nine-year-old male with trisomy 21, end-stage renal disease (ESRD) due to reflux nephropathy presented with suspected peritoneal dialysis (PD) catheter-associated peritonitis. One week after receiving an intraperitoneal antibiotic, he presented again with persistent peritonitis symptoms and bloody PD fluid. He underwent exploratory laparotomy, abdominal washout, and PD catheter removal.  Mycobacterium abscessus  ( M. abscessus)  was found in the intraoperative peritoneal fluid culture. After the catheter removal, the child's symptoms significantly improved without antimicrobial medications. He was maintained on hemodialysis three times a week and underwent a successful kidney transplant eight months after this episode. Non-tuberculous mycobacterial peritonitis should be considered in patients with culture-negative peritonitis when there is no intraperitoneal antibiotic response.  M. abscessus  is a rapidly growing atypical Mycobacterium found in the environment and can contaminate medical devices. Our case involved an infection from a contaminated PD catheter since the patient's symptoms improved after PD catheter removal., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Autosomal recessive polycystic kidney disease (ARPKD) is caused by a mutation in the polycystic kidney and hepatic disease-1 (PKHD1) gene and is an important inherited cause of chronic kidney disease in children. The most typical presentations in neonates are massively enlarged kidneys with variable echogenicity, multiple small cysts, and congenital hepatic fibrosis. Potter sequence with pulmonary hypoplasia can present due to oligohydramnios. Severe pulmonary hypoplasia can lead to respiratory insufficiency and perinatal death. Some affected children can develop end-stage renal disease in early childhood or adolescence. Here, we report the clinical presentations, management, and renal outcomes of three neonatal cases of ARPKD from our center., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Khin et al.)

Aims: To determine the roles of matrix metallopeptidase-9 (MMP9) on human coronary artery smooth muscle cells (HCASMCs) in vitro , early beginning of atherosclerosis in vivo in diabetic mice, and drug naïve patients with diabetes., Methods: Active human MMP9 (act-hMMP9) was added to HCASMCs and the expressions of MCP-1, ICAM-1, and VCAM-1 were measured. Act-hMMP9 (n=16) or placebo (n=15) was administered to diabetic KK.Cg- A y /J (KK) mice. Carotid artery inflammation and atherosclerosis measurements were made at 2 and 10 weeks after treatment. An observational study of newly diagnosed drug naïve patients with type 2 diabetes mellitus (T2DM n=234) and healthy matched controls (n=41) was performed and patients had ultrasound of carotid arteries and some had coronary computed tomography angiogram for the assessment of atherosclerosis. Serum MMP9 was measured and its correlation with carotid artery or coronary artery plaques was determined., Results: In vitro , act-hMMP9 increased gene and protein expressions of MCP-1, ICAM-1, VCAM-1, and enhanced macrophage adhesion. Exogenous act-hMMP9 increased inflammation and initiated atherosclerosis in KK mice at 2 and 10 weeks: increased vessel wall thickness, lipid accumulation, and Galectin-3+ macrophage infiltration into the carotid arteries. In newly diagnosed T2DM patients, serum MMP9 correlated with carotid artery plaque size with a possible threshold cutoff point. In addition, serum MMP9 correlated with number of mixed plaques and grade of lumen stenosis in coronary arteries of patients with drug naïve T2DM., Conclusion: MMP9 may contribute to the initiation of atherosclerosis and may be a potential biomarker for the early identification of atherosclerosis in patients with diabetes., Clinical Trial Registration: https://clinicaltrials.gov, identifier NCT04424706., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (Copyright © 2024 Liu, Su, Loo, Gao, Khin, Kong, Dalan, Su, Lee, Ma and Ye.)

Diet-microbiota interactions are emerging as important contributors in the pathogenesis of inflammatory bowel diseases (IBD), characterized by chronic inflammation of the GI tract. The aryl hydrocarbon receptor (AhR) transcription factor regulates xenobiotic metabolism and is activated by exogenous ligands, including indole-3-carbinole (I3C), which is found in cruciferous vegetables. However, studies investigating the impact of dietary I3C and AhR in preclinical models resembling human IBD are lacking. Mice (WT or AhR KO in IECs, 6-8 weeks) or SAMP/YitFC and AKR/J control (4 weeks, m/f) were fed an AhR ligand-depleted or I3C (200 ppm)-supplemented diet. There were increased levels of LPS and exacerbated inflammation, resulting in increased mortality in AhR ΔIEC mice fed the AhR ligand-depleted diet in response to chronic DSS. The mechanisms underlying the protective effects of I3C supplementation during colonic colitis involved amelioration of intestinal inflammation and restoration of the altered gut microbiota, particularly the families of clostridicae and lachnospriaceae. Furthermore, the AhR-depleted diet led to the emergence of pathobiont Parvibacter caecicola in WT mice. SAMP/YitFc mice with spontaneous ileitis showed significant recovery in epithelial abnormalities when fed dietary I3C. These data demonstrate the critical role of AhR and the mechanisms of dietary I3C in maintaining epithelial homeostasis and ameliorating inflammation.

Background: IgA vasculitis (IgAV) is the most common type of vasculitis in children. There is a lack of consensus for management of significant IgAV nephritis (IgAVN). This study was designed to identify the most used treatment options and describe their efficacy., Methods: This is a multicenter retrospective study of children age 1-21 years with IgAVN who were managed for at least 6 months by a nephrologist. Subjects with at least microscopic hematuria and proteinuria and/or decreased kidney function were enrolled. Kidney outcome was assessed by eGFR and urine protein/creatinine (UPC) ratios at 2-4 weeks, 3, 6, and 12 months post-diagnosis., Results: A total of 128 subjects with median age of 7 years (range 2-18) were included. Of these, 69 subjects had kidney biopsy with crescents detected in 53%. AKI (P = 0.039), nephrosis (P = 0.038), and crescents on biopsy (P = 0.013) were more likely in older patients. Patients with UPC > 1 mg/mg were more likely to get a kidney biopsy (P < 0.001) and to be treated with steroids ± immunosuppressive (IS) agents (P = 0.001). Sixty-six percent of patients were treated with steroids and/or IS agents for variable durations. Anti-metabolite agents were the most common IS agents used with variability in dosing and duration. At 12 months, most subjects had a normal eGFR (79%) (median 123, range 68-207 mL/min/1.73 m 2 ) and no proteinuria (median UPC 0.15, range 0.01-4.02 mg/mg)., Conclusions: IS agents are frequently used in managing IgAVN associated with heavy proteinuria, nephrosis, and/or AKI. Prospective studies are needed to determine indications and needed duration of IS therapy. A higher resolution version of the Graphical abstract is available as Supplementary information., (© 2022.
