Biomechanical analysis of step-up and step-down tasks in knee osteoarthritis: Insights from leading and trailing limbs.

Background: Stair climbing tests are pivotal when assessing physical performance in knee osteoarthritis patients, yet the biomechanical strategies that underpin poor stair climbing ability are heterogeneously reported. Single step tasks emulate a step-by-step gait pattern, an approach associated with knee pain when stair climbing. The objective of this study is to analyse the biomechanics and electromyography activity of both the leading and trailing limbs during single Step-up and Down tasks in knee osteoarthritis patients.

Jets Downstream of Collisionless Shocks: Recent Discoveries and Challenges.

Plasma flows with enhanced dynamic pressure, known as magnetosheath jets, are often found downstream of collisionless shocks. As they propagate through the magnetosheath, they interact with the surrounding plasma, shaping its properties, and potentially becoming geoeffective upon reaching the magnetopause. In recent years (since 2016), new research has produced vital results that have significantly enhanced our understanding on many aspects of jets.

Biomechanical differences of Asian knee osteoarthritis patients during standing and walking using statistical parametric mapping: A cross-sectional study.

Background: Biomechanics of knee osteoarthritis (KOA) patients have been extensively studied using motion capture systems, but less have explored standing knee joint angles with the walking parameters, particularly in Asians. We aim to determine gait biomechanical differences between healthy and KOA participants in an Asian population using One-dimensional Statistical Parametric Mapping (SPM1D) and explore if they are associated with standing joint angles.

Methods: A total of 20 KOA and 24 healthy stood upright and walked 10 m at self-selected speeds.

Transitions of Care Pharmacist Impact Following Hospitalization for Acute Myocardial Infarction.

Patients admitted with acute myocardial infarction (AMI) are at high risk for morbidity and rehospitalizations. Pharmacists can play a vital role in secondary prevention by providing services such as medication reconciliation and patient education upon discharge. The purpose of this study was to evaluate the impact of a pharmacist-led transitions of care (TOC) service on readmissions in patients hospitalized with AMI.

A Standard Measure of Structural Racism, Do We Have One? Can We Have One? A Narrative Review of Commonly Used Measures and Domains of Use.

Background: A lack of a "gold standard" operationalized index to measure structural racism (SR) in the current literature limits the comparison of the evidence available. This study aims to synthesize the measures of SR from the current literature to identify the measures used to date, study the indicators included, and investigate its expanding domain.

Methods: A literature search of original quantitative studies in the Google Scholar and PubMed databases for articles dated January 1, 2000-July 31, 2023, was conducted with search terms: ["Institutionalized Racism" OR "Systemic Racism", OR "Structural Racism"] AND "Health" AND "United States.
