Genome wide association studies have identified numerous single nucleotide polymorphisms (SNPs) associated with obesity, yet effect sizes of individual SNPs are small. Therefore, the aim of our study was to investigate whether a genetic risk score (GRS) comprising risk alleles of SNPs identified in the GIANT consortium meta-analyses shows association with body mass index (BMI) and other BMI related metabolic alterations in a cohort with an extreme phenotype. Genotyping of 93 SNPs was performed in 314 obese individuals (mean BMI 40.5 ± 7.8 kg/m², aged 45 ± 12 years), participating in a standardized weight reduction program, and in 74 lean controls (mean BMI 24.6 ± 3.3 kg/m², aged 41.7 ± 13.4 years). ⋯ GRS was significantly different between controls and obese individuals (unweighted GRS: 86.6 vs 89.0, P = .002; weighted GRS: 84.9 vs 88.3, P = .005). Furthermore, linear regression analysis showed significant associations of GRS with BMI ( P < .0001), weight ( P = .0005), waist circumference ( P = .0039), fat mass ( P < .0001) and epicardial fat thickness ( P = .0032), yet with small effect sizes ( r ² < 0.06). In conclusion, in our study GRS could differentiate between extreme obese and lean individuals, and was associated with BMI and its related traits, yet with small effect sizes.

Surgical site infection (SSI) is one of the most frightening complications after surgery. Adhesive drapes (AD) are widely used as an infection prevention tool. They can be non-impregnated or iodophor-impregnated, although non-impregnated are less used as they might be related to higher number of infections. One of the most common ways to study their efficacy is by analyzing the intraoperative contamination, which is a useful primary endpoint as it does not need follow-up and it has been strongly associated with infections. Therefore, we believe a systematic review (SR) and meta-analysis is needed to determine which is the literature available about this topic and to explore their results. ⋯ The evidence regarding the benefits of using iodophor-impregnated adhesive drapes (IIAD) is scarce. Therefore, this SR and meta-analysis is required to determine if they are related with a lower intraoperative contamination incidence, compared to no AD.

Rheumatoid arthritis (RA) is a type of difficult-to-cure arthralgia with a worldwide prevalence. It severely affects people's living standards. For a long time, bee venom has been used to treat RA and has shown good results. Melittin is the main active component of bee venom used for RA treatment, but the molecular mechanism of melittin in RA treatments remains unclear. ⋯ RA treatment with melittin is the result of a multi-target and multi-pathway interaction. This study offers a theoretical basis and scientific evidence for further exploring melittin in RA therapy.

Currently, it is unclear whether creatine phosphokinase (CPK) affects bone mineral density (BMD) in adolescents. We sought to clarify the relationship between CPK and total BMD in adolescents aged 12 to 19 years within normal values by conducting this study. A cross-sectional study was conducted using the 2011 to 2018 National Health and Nutrition Survey data to examine 1188 males (average age, 15.2 years) and 1629 females (average age, 15.4 years). ⋯ And the phase relationship between total BMD and CPK was further enhanced in boys. The results of our study show that CPK levels within the normal range are positively associated with total BMD in adolescents aged 12 to 19 years. Additionally, CPK may be a potential biomarker of bone health among adolescents.

Self stigmatization, which occurs as a result of internalization of public stigma in severe mental illnesses, is a factor that impairs the mental well-being of individuals and their compliance with treatment. Data on exactly which factors are associated with internalized stigma are still insufficient. Our aim in this clinical study is to investigate the relationship between internalized stigma and religious coping in patients with schizophrenia. ⋯ There was a significant negative correlation between ISMI total score and positive religious coping (r: -0.256, P: .002), a significant positive correlation with negative religious coping (r: 0.683, P < .001). Multiple linear regression analysis was applied to reveal the explanatory effect of age, duration of illness and religious coping on internalized stigma, and according to the model obtained (R = 0.729, R2 = 0.516, F = 32.071, P < .001), 51.6% of the change in the total score of the ISMI can be explained by this model. The significant relationship between positive and negative religious coping and internalized stigma in patients included in the study suggests that it may be beneficial to consider religious coping attitudes in addition to other interventions in the fight against stigma in severe mental illnesses such as schizophrenia.
