Differences in microorganism profile in periprosthetic joint infections of the hip in patients affected by chronic kidney disease.

Background: Patients affected by chronic kidney disease (CKD) are at increased risk of periprosthetic joint infection (PJI) after total hip arthroplasty (THA). This patient population has a higher risk of recurrent infections and hospitalization. The aim of this study is to compare the profile of microorganisms in patients with CKD and PJI of the hip versus controls and to individuate potentially unusual and drug-resistant microorganisms among the causative bacteria.

Testosterone/cortisol ratio: gender effect and prediction of podium results in beach sprint master rowers.

Objective: The purpose of this study was to address the lack of data on the stress and motivation response in master athletes during competitions, as athletic performance in this age group can be significantly impacted by stress rather than appropriate training.

Methods: Coastal rowing beach sprint master athletes aged 43-57 years were examined to assess the saliva levels of stress biomarkers, cortisol, and testosterone. Specifically, samples were collected at awakening and before and after the boat race.

Unraveling the molecular basis for G-quadruplex-binders to ALS/FTD-associated G4C2 repeats of the C9orf72 gene.

The most recurrent familial cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) is the presence of an abnormal number of intronic GGGGCC (G4C2) repetitions in the C9orf72 gene, which has been proposed to drive ALS/FTD pathogenesis. Recently, it has been shown that such G4C2 repetitions can fold into G-quadruplex (G4) secondary structures. These G4s have been selectively stabilized by small-molecule binders, furnishing proof of principle that targeting these non-canonical nucleic acid sequences represents a novel and effective therapeutic strategy to tackle neurodegenerative disorders.

Classification of Physical Activity Programs Based on the Kellgren & Lawrence Scale for Knee Osteoarthritis: A Systematic Review.

Introduction: Knee osteoarthritis is a common orthopaedic disease, is the leading cause of disability in the elderly, and can lead to pain, loss of function, and reduced quality of life. This research aims to determine how PA programs can be effectively classified and customised to align with the stages of knee OA according to the KL classification.

Objective: The research aims to fill the gap in understanding the relationship between the type and intensity of PA and the stages of OA as defined by the KL classification.
