Objective: Cerebral blood flow (CBF) decline is increasingly recognized as an area of importance for targeting neurodegenerative disorders, yet full understanding of the mechanisms that underlie CBF changes are lacking. Animal models are crucial for expanding our knowledge as methods for studying global CBF and neurovascular coupling in humans are limited and require expensive specialized scanners.
Methods: Use of appropriate animal models can increase our understanding of cerebrovascular function, so we have combined chronic cranial windows with in vivo two-photon and laser speckle microscopy and ex vivo capillary-parenchymal arteriole (CaPA) preparations.
Background: Small bowel obstructions (SBOs) are a common complication following staged IPAA. Our goal was to compare early post-operative SBO outcomes between different staged ileal pouch-anal anastomosis (IPAA) and to further analyze the type of procedures required in patients who needed operative management of SBO.
Methods: In this retrospective cohort study, we selected all patients who presented to our tertiary care center between 2008 and 2017, with ulcerative colitis or IBD-Unspecified colitis and who underwent a primary total proctocolectomy with IPAA for medically refractory disease or dysplasia (n = 623).
Introduction: Accelerometer-derived physical activity (PA) from cardiac devices are available via remote monitoring platforms yet rarely reviewed in clinical practice. We aimed to investigate the association between PA and clinical measures of frailty and physical functioning.
Methods: The PATTErn study (A study of Physical Activity paTTerns and major health Events in older people with implantable cardiac devices) enrolled participants aged 60 + undergoing remote cardiac monitoring.
