Cerebral Blood Flow Dynamics in Neurogenic Orthostatic Hypotension: A Systematic Review and Meta-Analysis.

Background: Neurogenic orthostatic hypotension (nOH) causes pathological falls in standing blood pressure that may or may not be symptomatic. nOH also raises the risk of poor neurological outcomes irrespective of symptom presence, possibly reflecting subclinical cerebral hypoperfusion. Dynamic changes in cerebral blood flow velocity (CBFv) help infer how blood pressure fluctuations influence CBFv and cerebral autoregulation.

"Where I Didn't Have to Hear Anything, and I Could Just Run": The Lived Sport Experiences of Deaf or Hard of Hearing Collegiate Athletes.

Accessible and inclusive participation in sport can provide significant physical, psychological, and social benefits to Deaf or hard of hearing (D/HH) athletes. To understand how to facilitate these benefits, the researchers explored the lived physical education and sport experiences of D/HH collegiate athletes. Six athletes representing six sports were recruited and interviewed.

"There's a Lifestyle, an Appreciation, a Beauty": An Interpretative Phenomenological Analysis of Masters Rowers.

Masters rowing has seen a measurable increase in participation, with masters rowers engaged in the sport for competition, health, and recreation reasons. Unlike other masters sports, masters rowing has a unique high level of synchronous, cooperative, and interdependent elements. To better understand the benefits and challenges of participation in competitive masters rowing, the purpose of this study was to explore the lived experiences of competitive masters rowers.

Longitudinal prevalence of neurogenic orthostatic hypotension in the idiopathic Parkinson Progression Marker Initiative (PPMI) cohort.

Background: Reported orthostatic hypotension (OH) prevalence in Parkinson's disease (PD) varies widely, with few studies evaluating specifically neurogenic-OH (nOH). The ratio of orthostatic heart rate (HR) to systolic blood pressure (SBP) change (Δ) is a valid screening method to stratify nOH/non-nOH but has had minimal epidemiologic application.

Objective: To estimate the prevalence of nOH and non-nOH in the PPMI using the ΔHR/ΔSBP ratio and examine associations between nOH and various motor and non-motor measures.
