During 12-weeks' treatment of Graves' hyperthyroidism, a single daily dose of 15 mg of MMI was much more effective in the induction of euthyroidism than a single daily dose of 150 mg of PTU. Once daily regimen of MMI not only decreased serum T3 and T4 levels more rapidly but also induced euthyroidism four times more effectively than did the once daily regimen of PTU. In the doses used in this study, MMI is preferable to PTU when a once-daily regimen of antithyroid drug is considered for the treatment of hyperthyroidism.

BackgroundSeveral type 2 diabetes (T2D) susceptibility loci identified via genome-wide association studies were found to be replicated among various populations. However, the influence of these loci on T2D in Thai population is unknown. The aim of this study was to investigate the influence of eight single nucleotide polymorphisms (SNPs) reported in GWA studies on T2D and related quantitative traits in Thai population.MethodsEight SNPs in or near the KCNQ1, CDKN2A/2B, SLC30A8, HHEX, CDKAL1, TCF7L2, MTNR1B, and UBE2E2 genes were genotyped. A case-control association study comprising 500 Thai patients with T2D and 500 ethnically-matched control subjects was conducted. Associations between SNPs and T2D were examined by logistic regression analysis. The impact of these SNPs on quantitative traits was examined by linear regression among case and control subjects.ResultsFive SNPs in KCNQ1 (rs2237892), CDK2A/2B (rs108116610, SLC30A8 (rs13266634), TCF7L2 (rs7903146) and MTNR1B (rs1387153) were found to be marginally associated with risk of developing T2D, with odds ratios ranging from 1.43 to 2.02 (p = 0.047 to 3.0 × 10–4) with adjustments for age, sex, and body mass index. Interestingly, SNP rs13266634 of SLC30A8 gene reached statistical significance after correcting for multiple testing (p = 0.0003) (p < 0.006 after Bonferroni correction). However, no significant association was detected between HHEX (rs1111875), CDKAL1 (rs7756992), or UBE2E2 (rs7612463) and T2D. We also observed association between rs10811661 and both waist circumference and waist-hip ratio (p = 0.007 and p = 0.023, respectively). In addition, rs13266634 in SLC30A8 was associated with glycated hemoglobin (p = 0.018), and rs7903146 in TCF7L2 was associated with high-density lipoprotein cholesterol level (p = 0.023).ConclusionOf the eight genes included in our analysis, significant association was observed between KCNQ1, CDKN2A/2B, SLC30A8, TCF7L2, and MTNR1B loci and T2D in our Thai study population. Of these, CDKN2A/2B, SLC30A8, and TCF7L2 genes were also significantly associated with anthropometric, glycemic and lipid characteristics. Larger cohort studies and meta-analyses are needed to further confirm the effect of these variants in Thai population.Electronic supplementary materialThe online version of this article (10.1186/s12881-018-0614-9) contains supplementary material, which is available to authorized users.

Fat and metabolic abnormalities and their associated factors in HIV-infected patients in Thailand were examined. Body fat and fasting lipids (total cholesterol, TC; triglyceride, TG; and HDL-cholesterol, HDL-c) were evaluated in 247 HIV-infected Thais. Body fat was evaluated by subjects and blinded observers, and measured using dual-energy X-ray absorptiometry. Descriptive statistics and logistic regression were used for analyses. Antiretroviral (ARV)-treated Thais were significantly older, more likely to be male, and had higher education and income compared to untreated subjects. The prevalence of lipoatrophy was 10.3% in ARV-naive patients, 36.7% in patients receiving non-protease inhibitor (PI)-based ARV, and 78.7% in PI-based ARV-treated patients (p < 0.001). Excess abdominal or neck fat was found in 0.8%, 6.7%, and 24.6% of the naive, non-PI-treated, and PI-treated, respectively (p < 0.001). Hypercholesterolemia (TC > or = 240 mg/dl) was found in 4.8%, 26.6%, and 42.6%; hypertriglyceridemia (TG > or = 150 mg/dl) in 8.2%, 48.3%, and 75.4%; and low HDL-c (HDL-c < 40 mg/dl) in 42.9%, 20.0%, and 31.2% of the naive, non-PI treated, and PI-treated, respectively (p < 0.05 for all). Central to peripheral fat ratios were 1.11 +/- 0.03, 1.45 +/- 0.06, and 1.93 +/- 0.08 for the naive, non-PI, and PI-treated, respectively (p < 0.001). Treatment was associated with abnormal fat. The adjusted ORs (95% CI) of lipoatrophy for excess fat were 4.6 (2.0-10.7); 6.3 (0.6-71.1) for ARV-naive vs. non-PI; 5.6 (3.4-9.1); 10.7 (3.4-33.8) for ARV-naive vs. PI, and 5.7 (2.4-13.9); 5.3 (1.2-11.4-13.9) for ARV-naive vs. PI. ARV-associated metabolic abnormalities are common in this non-Western population. Appropriate selection and monitoring of ARV treatment are critical to minimize the risk of long-term complications.

Although a significant number of patients became overweight or obese after being treated with CS, most gained <10 kg. Obesity secondary to CS treatment in SLE patients was significantly correlated with baseline BMI, gender and cumulative CS dosage.

Purpose This study investigated the prevalence and characteristics of prediabetes (PreDM) and metabolic syndrome (MetS) in seemingly healthy persons attending a health check-up clinic at a tertiary care hospital. Patients and Methods This was a cross-sectional study that enrolled 1213 subjects (339 male, 874 female) who underwent an annual health check-up at Siriraj Hospital, Bangkok, Thailand from 2009 to 2019. Factors that independently related to PreDM were analyzed using unconditional logistic regression analysis with adjustments for age, BMI, and gender. Results The prevalence of PreDM and MetS was 54.3% and 19.7% respectively. Participants with impaired fasting glucose (IFG) and glycated hemoglobin (HbA 1c ) 38.8–46.4 mmol/mol had significantly higher waist circumference (WC) and blood pressure (BP) compared to those with IFG or HbA 1c 38.8–46.4 mmol/mol alone ( P < 0.05). Among three PreDM subgroups, the average age was lowest in the HbA 1c 38.8–46.4 mmol/mol subgroup ( P < 0.001). PreDM participants with MetS were older ( p = 0.03), had higher WC, BP, fasting plasma glucose and serum triglyceride level (all P < 0.001) but had lower serum high-density lipoprotein (HDL) cholesterol level ( P < 0.001). Multivariate analysis revealed high MetS score, obesity, and low serum HDL cholesterol level to be independently associated with PreDM with odds ratios of 9.02 (95% confidence interval [CI]: 4.03–20.18), 1.8 (95% CI: 1.07–3.04), and 1.42 (95% CI: 1.02–1.96), respectively. Conclusion The prevalence of PreDM and MetS was relatively high in seemingly healthy persons. Distinct PreDM subgroups with or without MetS exhibited diverse clinical and biochemical features suggesting dissimilar pathogenesis.

Objective: To compare academic outcomes between integrated flipped classroom (FC) and solely traditional lecture (TL) teaching approach among 2 nd year medical students in Epidemiology and Biostatistics course. Methods: General information and academic achievements including grade point average, scores of the basic statistics course and scores of Epidemiology and Biostatistics course were extracted from the database of the Education Department. The records were excluded if they belonged to repeated or transferred students. The students in 2014 and 2015 academic year represented the TL group and the FC group respectively. The main outcome was the examination score from the two groups which was converted to a comparable scale out of a hundred. Results: Six-hundred twenty-eight records were included in the analysis. Based on independent t-test, the TL group showed higher mean score as compared to the FC group (p-value < 0.01). Further comparison using ANCOVA adjusted for age, gender, hometown location, high school location, grade point average and score of a basic statistics course showed a higher score in the TL group (p-value < 0.01). Conclusion: TL yielded higher examination score than FC from this retrospective study.
