Popliteal Artery Entrapment Syndrome as a Differential Diagnosis for Knee Pain: A Case Report.

Popliteal artery entrapment syndrome has congenital and functional causes. It mostly affects young people. There are six types of popliteal artery entrapment syndrome.

Quality and readability of online information on Keratoconus in Portugal and Brazil.

Introduction: Keratoconus patients turn to the internet for answers to their disease expectations. Webpages are not filtered or submitted to evaluation before getting published. We aim to evaluate the quality and readability of the online information regarding keratoconus in Portugal and Brazil.

MRI-Based Morphometric Comparison of Lower Leg Muscles and Tendons in Individuals With Medial Tibial Stress Syndrome.

Runners frequently suffer from medial tibial stress syndrome (MTSS), often linked to excessive eccentric muscle contractions causing periosteal traction by the muscles in the deep posterior compartment. However, the effects of MTSS on these muscles and tendons remain underexplored. This study is aimed at investigating changes in muscle and tendon volumes in this compartment, as well as cross-sectional area measurements, using magnetic resonance imaging.

A shorter linker in the bispecific antibody RmAb158-scFv8D3 improves TfR-mediated blood-brain barrier transcytosis in vitro.

Transferrin Receptor (TfR)-mediated transcytosis across the blood-brain barrier (BBB) enables the uptake of bispecific therapeutic antibodies into the brain. At therapeutically relevant concentrations, bivalent binding to TfR appears to reduce the transcytosis efficiency by receptor crosslinking. In this study, we aimed to improve BBB transcytosis of symmetric antibodies through minimizing their ability to cause TfR crosslinking.

Report of the Italian Cohort with Activated Phosphoinositide 3-Kinase δ Syndrome in the Target Therapy Era.

Background: Activated Phosphoinositide 3-Kinase (PI3K) δ Syndrome (APDS), an inborn error of immunity due to upregulation of the PI3K pathway, leads to recurrent infections and immune dysregulation (lymphoproliferation and autoimmunity).

Methods: Clinical and genetic data of 28 APDS patients from 25 unrelated families were collected from fifteen Italian centers.

Results: Patients were genetically confirmed with APDS-1 (n = 20) or APDS-2 (n = 8), with pathogenic mutations in the PIK3CD or PIK3R1 genes.
