A multi-site study was conducted to evaluate the efficacy of the Keeogo™ exoskeleton as a mobility assist device for use in the clinic and at home in people with knee osteoarthritis (KOA). Twenty-four participants were randomized in a two-stage cross-over design that evaluated the immediate effects of using the exoskeleton in the clinic and the cumulative effects of training and home use. Immediate effects were quantified by comparing 1) physical performance with|without (W|WO) the device during a battery of mobility tests, and 2) physical activity levels at home (actigraphy) for one month, two weeks W|WO the device. Cumulative effects were quantified as change in physical performance W and WO over time. WOMAC and other self-report scales were measured and usability assessed. There were no immediate effects on physical performance or physical activity at home; however, there were cumulative effects as indicated by improved stair time ( = .001) as well as improved WOMAC pain ( = .004) and function ( = .003). There was a direct relationship between improved physical function and improved WOMAC pain (r = -.677, < .001) and stiffness (r = .537, = .007). Weight and battery life were identified as important to usability. A full-scale RCT with more participants, longer study period, and better usage monitoring is warranted.

The highly publicized murders of Breonna Taylor, George Floyd, and Ahmaud Arbery in 2020 sparked public outrage and widespread discussion around anti-Black violence. While some studies have examined the effects of anti-Black violence exposure on mental health outcomes, there is a paucity of research that explores how these racially charged events contribute to cumulative stress and "weathering" for Black people, particularly. Informed by racial battle fatigue theory, this in-depth qualitative study explored the lived experiences of 30 Black male and female undergraduate college students (aged 18-28) exposed to highly publicized acts of anti-Black violence.

Background: Reduction of intracellular Na accumulation through late Na current inhibition has been recognized as a target for cardiac Ca handling which underlies myocardial contractility and relaxation in heart failure (HF). Riluzole, an Na channel blocker with enhancement of Ca-activated K channel function, used for management of amyotrophic lateral sclerosis (ALS), is effective in suppressing Ca leak and therefore may improve cardiac function.
Objectives: The study aim was to investigate whether riluzole lowers HF incidence.

Background: Neurofilament light chain protein (NfL) in cerebrospinal fluid (CSF) reflects the severity of neurodegeneration, with its altered concentrations discovered in Parkinson's disease (PD) and Parkinson's disease dementia (PD-D).
Method: A total of 259 people were recruited in this study, including 85 healthy controls (HC) and 174 neonatal PD patients from the Parkinson's Progression Markers Initiative (PPMI). Multiple linear regression and linear mixed effects models were used to examine the associations of baseline/ longitudinal CSF NfL with cognitive decline and other CSF biomarkers.
Background: Prolonged discrimination is psychosocial stressor, influencing mortality rates and contributing to cardiovascular and mental health disorders among Black individuals. Allostatic load (AL), the wear and tear of stress is a biological cumulative risk that links psychosocial stressors to adverse health outcomes. Currently, a consolidate review of evidence underscoring discrimination and AL in Black individuals is not available.

With evidence that salpingectomy is effective in preventing high grade serous carcinoma, it is time to consider offering this procedure to people at higher-than-average lifetime risk for ovarian cancer, despite not having a pathogenic genetic variant that increases risk for ovarian cancer. This targeted approach has potential to be effective at reducing ovarian cancer incidence, and unlike opportunistic salpingectomy is focused on people with an increased lifetime risk of ovarian cancer. However, the acceptability of this approach within the population of potential patients remains unknown.
