Digital measurement of ocular microtremor in Parkinson's disease: Protocol for a pilot study to assess reliability and clinical validation.

Ocular microtremor (OMT) is a fixational eye movement that cannot be seen with the naked eye but is always present, even when the eye appears motionless/still. The link between OMT and brain function provides a strong rationale for investigation as there lies potential for its use as a biomarker in populations with neurological impairments. OMT frequency is typically 70-80Hz in healthy adults and research suggests that this will be reduced in those with neurological disease such as Parkinson's Disease (PD).

Antihypertensive Deprescribing and Functional Status in VA Long-Term Care Residents With and Without Dementia.

Background: Deprescribing antihypertensives is of growing interest in geriatric medicine, yet the impact on functional status is unknown. We emulated a target trial of deprescribing antihypertensive medications compared with continued use on functional status measured by activities of daily living (ADL) in a long-term care population.

Methods: We included 12,238 Veteran Affairs long-term care residents age 65+ who had a stay ≥ 12 weeks between 2006 and 2019.

Convergent evolution of type I antifreeze proteins from four different progenitors in response to global cooling.

Alanine-rich, alpha-helical type I antifreeze proteins (AFPs) in fishes are thought to have arisen independently in the last 30 Ma on at least four occasions. This hypothesis has recently been proven for flounder and sculpin AFPs, which both originated by gene duplication and divergence followed by substantial gene copy number expansion. Here, we examined the origins of the cunner (wrasse) and snailfish (liparid) AFPs.

Frailty and Long-Term Health Care Utilization After Elective General and Vascular Surgery.

Importance: Surgical quality improvement efforts have largely focused on 30-day outcomes, such as readmissions and complications. Surgery may have a sustained impact on the health and quality of life of patients considered frail, yet data are lacking on the long-term health care utilization of patients with frailty following surgery.

Objective: To examine the independent association of preoperative frailty on long-term health care utilization (up to 24 months) following surgery.

Taking risk to heart: An evaluation of cardiometabolic risk and screening guideline adherence in outpatients with spinal cord injury.

Objectives: To evaluate cardiometabolic disease (CMD) in outpatients with spinal cord injury/disease (SCI/D). The study aims were to (1) estimate the prevalence of CMD risk factors in a cohort of Canadian adults with SCI/D; (2) assess whether the frequency of CMD screening aligns with evidence-based guidelines; and (3) gain a preliminary understanding of the barriers to CMD screening and/or treatment within a rehabilitation program setting.

Design: Quality improvement initiative involving chart review extracting the presence of and frequency of screening for four CMD risk factors (obesity, hypertension, dyslipidemia, diabetes mellitus).
