Background/Aims: To investigate the potential of maternal first-trimester triglyceride (TG) to high-density lipoprotein cholesterol (TG/HDL-c) ratio, triglyceride glucose index (TyG) and total cholesterol (TC)/HDL-c to predict the risk of later gestational diabetes mellitus (GDM) and large for gestational age (LGA) newborn in Chinese women. Methods: We included 352 women with a singleton pregnancy, who were followed up prospectively from the first prenatal visit until delivery. Fasting glucose and plasma lipid profiles including TG, TC, HDL-c, and low-density lipoprotein cholesterol (LDL-c) were measured in the first trimester. A binary logistic regression analysis was performed to determine the odds ratios (ORs) and 95% confidence intervals (CIs) of GDM and LGA according to tertiles of those indices, respectively. Receiver-operating characteristic curve (ROC) and areas under the curve (AUC) were employed to evaluate the ability of those indices to predict the risk of GDM and LGA infants, and differences in the AUC values between them were compared. Results: Women with the top tertile of TG/HDL-c or TyG other than TC/HDL-c had a significantly higher risk of GDM (OR_TG/HDL-c=2.388, 95% CI 1.026– 5.467; OR_TyG=3.535, 95% CI 1.483– 8.426, respectively) and LGA infant delivery (OR_TG/HDL-c=3.742, 95% CI 1.114– 12.569; OR_TyG=3.011, 95% CI 1.012– 8.962, respectively) than women with the lowest tertile of TG/HDL-c or TyG after adjusting for confounders. The AUC of TG/HDL-c and TyG to detect GDM was 0.664 (95% CI 0.595– 0.733) and 0.686 (95% CI 0.615– 0.756), respectively, and that to detect LGA was 0.646 (95% CI 0.559– 0.734) and 0.643 (95% CI 0.552– 0.735), respectively (all P < 0.01). There were no statistical differences between TG/HDL-c and TyG in the ability of predicting the risk of GDM or LGA infants. Conclusion: Maternal first-trimester TG/HDL-c and TyG are both good indicators in predicting the risk of later GDM and LGA newborn, and it may be useful to evaluate them in early pregnancy.

Purpose: Red blood cell (RBC) folate indicates long-term folate intake, and methylenetetrahydrofolate reductase (MTHFR) gene is the main gene affecting folate status. Increasing evidence suggests an association between gestational diabetes mellitus (GDM) and increased folate levels. Whether RBC folate concentrations in the first trimester of pregnancy or polymorphisms of MTHFR C677T (rs1801133) affect GDM risk in Chinese pregnant women remains unknown. Therefore, we analyzed the associations of RBC folate concentrations and rs1801133 polymorphisms with GDM risk among pregnant women in China. Methods: A total of 366 women with a singleton pregnancy were followed prospectively from their first prenatal visit to delivery. RBC folate concentrations and rs1801133 polymorphisms were assessed during the first trimester of pregnancy. Binary logistic regression analyses were performed to determine the odds ratios (ORs) of GDM and 95% confidence intervals (CIs) by using the RBC folate concentration quartiles and rs1801133 polymorphisms. Results: Participants with the TT genotype had the highest RBC folate concentrations. Those with heterozygous or homozygous variants did not have a significantly higher risk of GDM than did women with C alleles. After adjustments for covariates, women in the highest quartile for RBC folate concentration had a higher risk of GDM (adjusted OR = 2.473, 95% CI = 1.013– 6.037, P = 0.047) than did those in the lowest quartile, but this association was nonsignificant after adjustment for rs1801133 polymorphisms. Conclusion: Higher RBC folate, partly caused by MTHFR 677C→T, may be associated with increased GDM risk, even in early pregnancy. Assessing RBC folate status and appropriately supplementing folate during early pregnancy, particularly for patients with MTHFR 677C→T, may prevent GDM. Further studies with larger populations are warranted.

Introduction: Although black-grained wheat (BGW) is recognized as a nutritional food for humans in China, it has yet to be utilized well for industrial applications, which can be attributed to the limited research data available on its health benefits. Thus, the hypothesis was tested that a daily substitution of BGW for a partial staple food would improve glycemia and inflammatory profile of type 2 diabetes mellitus (T2DM) patients by a randomized controlled trial. Materials and methods: A total of 120 patients were randomly divided between control group (diet control and nutritional education) and BGW group (daily substitution of BGW for a partial staple food). Results: Based on the significant difference between BGW and control groups (P69 g/day. Conclusion: These findings support the hypothesis that BGW may improve glycemia and the inflammatory profile in T2DM patients.

Convenient food made of extruded adzuki bean attenuates inflammation and improves glycemic control in patients with type 2 diabetes: a randomized controlled trial Yanping Liu,1,* Qiyan Wang,1,* Shanshan Li,1 Yanfen Yue,2 Yuling Ma,3 Guixing Ren3 1Nutrition Department, Chinese Academy of Medical Sciences, Peking Union Medical College, Peking Union Medical College Hospital, Beijing, China; 2Nutrition Department, Pinggu Hospital of Traditional Chinese Medicine, Beijing, China; 3Institute of Crop Sciences, Chinese Academy of Agricultural Sciences, Beijing, China *These authors contributed equally to this work Objective: Extrusion is a widely used food processing technology. The aim of this study was to investigate the effects of extruded adzuki bean convenient food (EABCF) on glycemic and inflammation control in type 2 diabetes mellitus (T2DM) patients.Patients and methods: In a randomized controlled trial, 120 T2DM patients were randomly assigned to a control diet group (the low glycemic index [LGI] group, assigned the traditional diabetic low glycemic index diet) or an intervention group (the EABCF group, assigned daily consumption of EABCF). Diet information and blood samples were collected at baseline and after a 4-week intervention. After excluding exogenous insulin users, a subgroup analysis based on baseline fasting insulin (FINS) levels was conducted, and Homeostasis Model Assessment (HOMA) was the target indicator.Results: A total of 106 patients completed the trial, and 89 participants were included in the subgroup analysis. After the intervention, glycemic control improved in both groups compared to baseline, but the difference was not statistically significant (p>0.05). However, the EABCF group showed decreased inflammation with significantly lower tumor necrosis factor alpha (TNF-α) level compared to the control group (adjusted p<0.01). There was also a slight increase in the interleukin-6 (IL-6) level in the EABCF group (adjusted p=0.004). Moreover, the subgroup analysis found that, after 4 weeks, a diet consisting of EABCF increased insulin secretion to normal levels in the group with hypoinsulinism (baseline FINS<5.2 mU/L). However, the difference only showed a trend toward statistical significance (0.05<p=0.079<0.1).Conclusion: EABCF had a similar hypoglycemic effect as the traditional diabetic LGI diet and showed a greater inhibitory effect on inflammation in T2DM patients. However, further clinical studies are needed to explore the underlying mechanism.

Introduction: The COVID pandemic prompted a significant increase in the utilization of telemedicine (TM) for substance use disorder (SUD) treatment. As we transition towards a “new normal” policy, it is crucial to comprehensively understand the evidence of TM in SUD treatment. This scoping review aims to summarize existing evidence regarding TM's acceptability, quality, effectiveness, access/utilization, and cost in the context of SUD treatment in order to identify knowledge gaps and inform policy decisions regarding TM for SUDs. Method: We searched studies published in 2012–2022 from PubMed, Cochrane Library, Embase, Web of Science, and other sources. Findings were synthesized using thematic analysis. Results: A total of 856 relevant articles were screened, with a final total of 42 articles included in the review. TM in SUD treatment was perceived to be generally beneficial and acceptable. TM was as effective as in-person SUD care in terms of substance use reduction and treatment retention; however, most studies lacked rigorous designs and follow-up durations were brief (≤3 months). Telephone-based TM platforms (vs video) were positively associated with older age, lower education, and no prior overdose. Providers generally consider TM to be affordable for patients, but no relevant studies were available from patient perspectives. Conclusions: TM in SUD treatment is generally perceived to be beneficial and acceptable and as effective as in-person care, although more rigorously designed studies on effectiveness are still lacking. Access and utilization of TM may vary by platform. TM service quality and costs are the least studied and warrant further investigations.
