Mapping the Evidence on Midline Catheter Tip Location, Confirmation Methods and Associated Characteristics: A Scoping Review

Nursing Open, Volume 13, Issue 10, October 2026.
ABSTRACT Background Midline catheters (MCs) are increasingly utilized as an alternative to peripheral and central venous catheters. However, the lack of standardized protocols for tip location and confirmation methods remains a significant barrier to patient safety and clinical decision‐making.

Persistent endothelial dysfunction is associated with exercise intolerance in adults despite preserved myocardial work 3 years after SARS‐CoV‐2 infection

Physiological Reports, Volume 14, Issue 19, October 2026.
Adults with Long COVID exhibited impaired aerobic capacity and persistent endothelial dysfunction despite preserved myocardial function approximately 3 years after SARS‐CoV‐2 infection. The association between flow‐mediated dilation (FMD) and exercise capacity suggests a potential contribution of peripheral vascular dysfunction to exercise intolerance.

Supraphysiological ascorbic acid infusion attenuates cerebrovascular dysfunction in middle‐aged and older adults

Physiological Reports, Volume 14, Issue 19, October 2026.
Young (Y) and middle‐aged and older (MA/O) community‐dwelling adults were recruited and randomized to acute ascorbic acid (AA) or saline (SAL) infusions, on separate days. Cerebrovascular reactivity (CVR) to transient hypercapnia (30 s) in the internal carotid artery (ICA), or sustained hypercapnia (3 min) in the middle cerebral artery (MCA), was ...
