Background
Recent research has demonstrated that Type 2 Diabetes (T2D) risk is influenced by a number of common polymorphisms, including MC4R rs17782313, PPARG rs1801282, and TCF7L2 rs7903146. Knowledge of the association between these single nucleotide polymorphisms (SNPs) and body weight changes in different forms of prediabetes treatment is still limited. The aim of this study was to investigate the association of polymorphisms within the MC4R, PPARG, and TCF7L2 genes on the risk of carbohydrate metabolism disorders and body composition changes in overweight or obese patients with early carbohydrate metabolism disorders.
Methods and results
From 327 patients, a subgroup of 81 prediabetic female patients (48.7 ± 14.8 years) of Eastern European descent participated in a 3-month study comprised of diet therapy or diet therapy accompanied with metformin treatment. Bioelectrical impedance analysis and genotyping of MC4R rs17782313, PPARG rs1801282, and TCF7L2 rs7903146 polymorphisms were performed. The MC4R CC and TCF7L2 TT genotypes were associated with increased risk of T2D (OR = 1.46, p = 0.05 and OR = 2.47, p = 0.006, respectively). PPARG CC homozygotes experienced increased weight loss; however, no additional improvements were experienced with the addition of metformin. MC4R TT homozygotes who took metformin alongside dietary intervention experienced increased weight loss and reductions in fat mass (p < 0.05).
Conclusions
We have shown that the obesity-protective alleles (MC4R T and PPARG C) were positively associated with weight loss efficiency. Furthermore, we confirmed the previous association of the MC4R C and TCF7L2 T alleles with T2D risk.
Purpose of the study was to study of psychocosial characteristics and prevalence of the emotional burnout syndrome among endocrinologists in the Republic of Tatarstan considering psychosocial and individual-personal factors.Materials and methods. We studied the psychological, physical, social characteristics of the respondents using the «Emotional burnout» level method by V. V. Boiko. Our research involved 72 endocrinologists. Respondents were grouped according to the following characteristics: by place of residence, work, employment, age and experience.Results. During the interpretation of the results we established that most of the endocrinologists had different stages of emotional burnout: stress, resistance and exhaustion. 76,4% of endocrinologists have manifestations of this syndrome. The prevalence of the formed syndrome of emotional burnout was 4,2%.Conclusions. The prevalence of syndrome increases from the age of the doctor, the duration of employment. Doctors living in the countryside have lower emotional burnout rates than urban residents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
