Factors Associated with HIV Risk Perception Among Cisgender Female Sex Workers in Brazil.

This study evaluated the association between HIV risk perception and sociodemographic and behavioral characteristics among cisgender female sex workers in the five regions of Brazil. A cross-sectional, multicenter study using respondent-driven sampling was used. Sex workers over 18 years of age and who reported commercial sex in the past four months were included.

A multi-model approach identifies ALW-II-41-27 as a promising therapy for osteoarthritis-associated inflammation and endochondral ossification.

Low-grade inflammation and pathological endochondral ossification are key processes underlying the progression of osteoarthritis, the most prevalent joint disease worldwide. In this study, we employed a multi-faceted approach, integrating publicly available datasets, analyses, experiments and models to identify new therapeutic candidates targeting these processes. Data mining of transcriptomic datasets identified EPHA2, a receptor tyrosine kinase associated with cancer, as being linked to both inflammation and endochondral ossification in osteoarthritis.

A comprehensive assessment of quality management methods in the SMESH study.

Background: This paper aims to instigate discussion and publication of methodologies applied to enhance quality management through comprehensive scientific reports. It provides a detailed description of the design, implementation, and results of the quality control program employed in the SMESH study.

Methods: Cross-sectional, multicenter, national study designed to assess the prevalence of human papillomavirus in sex workers and in men who have sex with men (MSM).

gene expression in infrapatellar fat pad is correlated with fat mass in obese patients with end-stage knee osteoarthritis.

Objective: To investigate associations between obesity-linked systemic factors and gene expression indicative for the inflammatory and fibrotic processes in the infrapatellar fat pad (IFP), in a population of obese patients with end-stage knee osteoarthritis (KOA).

Methods: We collected human IFPs from 48 patients with a mean body mass index (BMI) of 35.44 ​kg/m during total knee replacement procedures.

Bone formation by human paediatric marrow stromal cells in a functional allogeneic immune system.

Allogeneic stem-cell based regenerative medicine is a promising approach for bone defect repair. The use of chondrogenically differentiated human marrow stromal cells (MSCs) has been shown to lead to bone formation by endochondral ossification in immunodeficient pre-clinical models. However, an insight into the interactions between the allogeneic immune system and the human MSC-derived bone grafts has not been fully achieved yet.
