Does living in a food desert impact weight loss after bariatric surgery?

Background: Lower access to fresh foods and lower income level are associated with greater obesity rates.

Objectives: We aim to study if weight loss 1 year after bariatric surgery is associated with living in areas defined as food deserts, that is, low access to foods and lower income.

Setting: Virginia Commonwealth University Hospital System, Richmond, VA; Academic Center.

Facial palsy after orthognathic surgery: An integrative analysis of literature reports and an illustrative case.

Background: To describe a case of a patient with PFP after orthognathic surgery and discuss cases reports on temporary or permanent facial paralysis, factors that trigger injury, and treatment for facial paralysis associated with orthognathic surgery.

Material And Methods: This study has two parts: a report of the case of a 20- year-old man who underwent orthognathic surgery for facial paralysis, and an integrative literature review on postoperative facial paralysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statements and performed survival analyses of all cases reported to date.

Results: The analysis was composed of 33 patients; 54,5% were male (mean age, 25 years).

Fast Analysis of Biobank-Size Data and Meta-Analysis using the BGLR R-package.

Analyzing human genomic data from biobanks and large-scale genetic evaluations often requires fitting models with a sample size exceeding the number of DNA markers used (n > p). For instance, developing Polygenic Scores (PGS) for humans and genomic prediction for genetic evaluations of agricultural species may require fitting models involving a few thousand SNPs using data with hundreds of thousands of samples. In such cases, computations based on sufficient statistics are more efficient than those based on individual genotype-phenotype data.

Mapping the relative accuracy of cross-ancestry prediction.

The overwhelming majority of participants in genome-wide association studies (GWAS) have European (EUR) ancestry, and polygenic scores (PGS) derived from EURs often perform poorly in non-EURs. Previous studies suggest that between-ancestry differences in allele frequencies and linkage disequilibrium are significant contributors to the poor portability of PGS in cross-ancestry prediction. We hypothesize that the portability of (local) PGS varies significantly over the genome.

Anxiolytic-like effects of Prolistarina: A bioinspired peptide from the venom of social wasps.

Pathological anxiety is among the most common psychiatric disorders. Despite advancements, predominant pharmacological treatments can lead to physical, chemical, and psychological dependence. Venoms of arthropods are important sources of neuroactive peptides with potential therapeutic applications for the treatment of neurological disorders.
