8%, p = 0.0001) in comparison to the CG. Three months after RT, there were less patients with oral nutritional support in the EG (79.1% vs 96.9%, p = 0.018), and the number of emergency visits (0.75 vs 1.1 episodes per patient, p = 0.021) and hospitalizations was also lower in this group (29% vs 59%, p = 0.044).
 
  The fast-track approach made early intervention possible. Therefore, patients maintained a better nutritional status, needed less nutritional support and their evolution improved, with a significant decrease in hospitalizations.

  To investigate the correlation between serum 25-hydroxyvitamin D (25(OH)D) and brachial-ankle pulse wave velocity (baPWV) and mortality among peritoneal dialysis (PD) patients.
 
  We retrospectively reviewed the data of 269 PD patients in our center from January 1, 2013, to December 31, 2018. Subjects were divided into groups according to serum 25(OH)D level based on a cut-off of 20 ng/ml. The general linear regression model was employed to explore the correlation between 25(OH)D and baPWV. The correlation between 25(OH)D and mortality was examined in Cox proportional hazards models.
 
  The mean (±SD) concentration of serum 25(OH)D was 17 (±7.2) ng/ml. Using linear regression analysis, and after adjusting for possible confounders, serum 25(OH)D concentration was found to be negatively associated with baPWV(β = -0.35, p < 0.001). Multivariate analysis showed that lower 25(OH)D level was significantly associated with higher total mortality in PD patients(< 20 ng/ml vs. ≥ 20 ng/ml; HR, 2.27; 95% CI, 1.04-4.93; P = 0.04)(as a continuous variable; HR, 0.94; 95% CI, 0.90-0.98; P = 0.01).
 
  Serum 25(OH)D concentration was a significant factor associated with baPWV and mortality among patients with PD. Further studies with larger sample sizes will be needed to confirm this correlation.

This meta-analysis ascertained forty-two studies on the efficacy (including response and remission) and side-effect issued before February 2020. Pooled analyses indicated significant associations of 1438A/G polymorphism (16 studies, 1931 subjects) and higher response within dominant model (OR 1.40, 95% CI 1.12-1.76); rs7997012G/A polymorphism (nine studies, 1434 subjects) and higher remission in overall models (dominant model OR 1.30, 95% CI 1.01-1.66; recessive model OR 2.20, 95% CI 1.53-3.16; homozygote model OR 2.73, 95% CI 1.78-4.17); 102T/C polymorphism (eight studies, 804 subjects) and reduced risk of side-effect within recessive (OR 0.57, 95% CI 0.4-0.83) and homozygote models (OR 0.54, 95% CI 0.29-0.99). For depression patients, genotyping of HTR2A polymorphisms is a promising tool for estimating the outcome and side-effect of antidepressants.Lipoblastomas are benign neoplasms of embryonal white fat that typically present in the first 3 years of life and show a lobular arrangement of maturing adipocytes with variable degrees of myxoid change. We systematically studied the clinicopathologic and genetic features of lipoblastomas arising in older children and adults. Cases with a diagnosis of lipoblastoma or maturing lipoblastoma in patients >3 years of age were retrieved from our archives. Immunostaining for CD34 and desmin and molecular studies (FISH, RNA sequencing) were performed. Twenty-two cases (8F; 14M) were identified in patients ranging from 4 to 44 years of age (median 10 years). Sites included extremity (n = 15), head and neck (n = 4), and trunk (n = 3) with tumor sizes varying from 1.6 to 17.5 cm (median 5). Only three tumors had histologic features of "conventional" lipoblastoma. The majority of tumors (n = 14) were composed of variably sized lobules of mature adipose tissue partitioned by thin fibrous septa ("maturing"). The remaining mistry for CD34 and desmin, and molecular genetic studies to identify PLAG1 rearrangements are the keys to recognizing these tumors.An amendment to this paper has been published and can be accessed via a link at the top of the paper.Organisms vary in their dispersal abilities, and these differences can have important biological consequences, such as impacting the likelihood of hybridization events. However, there is still much to learn about the factors influencing hybridization, and specifically how dispersal ability affects the opportunities for hybridization. Here, using the ecological replicate system of dove wing and body lice (Insecta Phthiraptera), we show that species with higher dispersal abilities exhibited increased genomic signatures of introgression. Specifically, we found a higher proportion of introgressed genomic reads and more reticulated phylogenetic networks in wing lice, the louse group with higher dispersal abilities. Our results are consistent with the hypothesis that differences in dispersal ability might drive the extent of introgression through hybridization.Appendicular lean mass (ALM) is a heritable trait associated with loss of lean muscle mass and strength, or sarcopenia, but its genetic determinants are largely unknown. Here we conducted a genome-wide association study (GWAS) with 450,243 UK Biobank participants to uncover its genetic architecture. A total of 1059 conditionally independent variants from 799 loci were identified at the genome-wide significance level (p  less then  5 × 10-9), all of which were also significant at p  less then  5 × 10-5 in both sexes. These variants explained ~15.5% of the phenotypic variance, accounting for more than one quarter of the total ~50% GWAS-attributable heritability. There was no difference in genetic effect between sexes or among different age strata.  https://www.selleckchem.com/products/zeocin.html  Heritability was enriched in certain functional categories, such as conserved and coding regions, and in tissues related to the musculoskeletal system. Polygenic risk score prediction well distinguished participants with high and low ALM. The findings are important not only for lean mass but also for other complex diseases, such as type 2 diabetes, as ALM is shown to be a protective factor for type 2 diabetes.
