ACTA ENDOCRINOLOGICA (BUC)

Background. Prevention of complications is widely considered as the main aim of diabetes control. And diabetes education is the cornerstone for type 2 diabetes (T2D) management. However, traditional lecture-based diabetes patient education activities have small and shortlasting efficacy. Therefore, technology-based initiatives for diabetes patient education are urgently required. Objective. To evaluate Guessing, a popular game, as tool in increasing complication awareness of patients with newly diagnosed T2D during diabetes care. Patients and Methods. In a cohort study, 103 patients were split into Guessing Game group and control group. The opinions of patients and educators in Guessing Game group were surveyed. Patient performance was evaluated by test scores and the attendance to diabetes complication screening clinic. Results. A majority of patients and all educators believed that Guessing Game enhanced complication awareness. Educatees achieved higher total scores and test scores in “Fill in the Gaps” (one of 2 types of test item), more actively attended complication screening clinic, after using Guessing Game as an education tool. Conclusion. Guessing Game is an attractive and effective educational intervention to increase complication awareness of T2D patients.

Background. To investigate the association between inflammatory factors, such as complete blood count (CBC) components, neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and gestational diabetes mellitus (GDM). Methods. A total of 635 pregnant women with GDM and 296 with normal pregnancies at 7–13 weeks of gestation who underwent prenatal examinations in the obstetrics department were enrolled (June 2020–December 2020). CBC parameters, including WBC, neutrophil, lymphocyte (LYM), monocyte (MON), red blood cell (RBC), hemoglobin (HGB), mean corpuscular volume (MCV), platelet (PLT), platelet accumulation (PCT), mean platelet volume (MPV), NLR, MLR, PLR, alanine transaminase (ALT), aspartate transaminase (AST), gamma-glutamyl transferase (GGT), and other parameters were assessed. The receiver operating characteristic (ROC) curve was used to analyze the screening effects of the variables on the development of GDM. Results. There were significant differences in the blood levels of WBC, NEU, LYM, MON, RBC, HGB, PCT, ALT, AST, GGT, NLR, and MLR between the GDM and control groups (P<0.05). The diagnostic level of MON was the highest among all factors. Conclusion. Inflammatory factors (WBC, NEU, LYM, MON, NLR, and MLR counts) were correlated with GDM.

Context. Data are conflicting concerning risk for Alzheimer’s disease (AD) and 5,10-methylenetetrahydrofolate reductase genetic variant (MTHFR C677T). Objective. The aim of the study was to investigate the associations of MTHFR C677T and risk of developing AD. Design and Methods. We searched the relevant articles by using Medline, web of science, and abstracts of conference proceedings. The meta-analysis and statistical analyses were performed using Stata. Results. In 33 included studies which provided 4518 cases and 5476 controls, the analysis for investigating the association between C677T allele T and the risk of developing AD relative to the allele C revealed no heterogeneity (p=0.088, I2=26.1%) between the 33 studies; the random effects (RE) pooled OR was significant: [RE OR=1.13(1.05-1.22)]. In subgroup analysis, we only observed the significant results in Asian populations. The pooled analysis for MTHFR 677 CT+TT vs. 677CC revealed a significant result [fixed effect (FE) OR=1.22(1.10-1.34)]. However, we did not observe significant associations in Europeans when comparing MTHFR 677 CT+TT with 677CC in subgroup analysis. The pooled analysis for MTHFR 677 TT vs. 677CC+CT did not reveal significant results: [FE OR=1.08(0.95-1.22)]. Conclusion. The risk allele T of MTHFR C677T is associated with high risk of AD in Asian populations, but not in Europeans.

Context. Results concerning the relationship between the risk of developing diabetic retinopathy (DR) and methylenetetrahydrofolate reductase genetic variant (MTHFR C677T) are inconclusive. Objective. The aim of the present analysis was to investigate the associations of DR with MTHFR C677T. Design and Methods. We searched the relevant articles by using Medline, web of science, and abstracts of conference proceedings. The meta-analysis was performed using Stata. Results. The included 7 studies provided 535 cases of DR and 759 controls. The main analysis for investigating the association between MTHFR 677 TT and the risk of developing DR relative to the 677 CC did not reveal significant heterogeneity (p=0.227, I2=27.6%) between the studies; the fixed effects (FE) pooled OR was significant: FE OR=1.84(1.30-2.61). The analysis for the association between MTHFR 677 TT and the risk of developing DR relative to the 677 CC+CT revealed heterogeneity (p=0.082, I2=48.9%) between the studies; the random effects (RE) pooled OR was significant: RE OR=1.72(1.07-2.76). In addition, T carriers have 31% higher risk of developing DR compared with homozygotes for C [OR=1.31(1.03-1.66)]. Conclusions. The present metaanalysis suggested an association between MTHFR C677T and DR and provided evidence that the TT genotype of the MTHFR C677T contributes to susceptibility to DR.

Context. The environmental occurrence of metformin has been frequently world-widely reported. Despite the diabetes susceptibility in the Chinese population, the studies on occurrence of metformin as environment disruptor in China are insufficient. Objective. To determine the occurrence trends and possible environmental pollution sources of metformin as an emerging micropollutant. Methods. High-performance liquid chromatographyelectrospray ionization-tandem mass spectrometry system was used to detect the metformin levels in water samples collected from the Xi’an city Moat, China once a year from 2017 to 2021. Correlations among the metformin levels in moat water, in surrounding hospital wastewater, and hospital metformin consumption data were assessed using Pearson, Spearman and Kendall’s tau-b correlation coefficients. Results. Occurrence of metformin was found in Xi’an city Moat water with levels in the range of 304- 793 ng/L. Significant correlations were found between the metformin levels in city moat water and the total (or outpatient) metformin utilization data of the hospital. Conclusion. Data suggested the potential environmental issues posed by metformin in Xi’an city in China. The metformin consumption volume in the surrounding hospitals, especially at the outpatient services, could be used to predict the metformin concentrations in the moat water.
