Second trimester uterine artery pulsatility index and chorionicity in twins [PDF]

, 2017
Background: We aimed to compare the second trimester uterine artery Pulsatility Index (PI) measurement in twin pregnancies according to the chorionicity and determine its effect on twin pregnancy outcome in terms of fetal and birth weight.Methods: All ...

Use of Platelet‐Rich Fibrin (PRF) on Palatal Wound Healing: A Narrative Review With Clinical Recommendations

Journal of Periodontal Research, EarlyView.
Based on the available evidence, the application of platelet‐rich fibrin (PRF) following free gingival graft (FGG) and subepithelial connective tissue graft (SCTG) harvesting appears to be a promising approach for enhancing wound healing, minimizing postoperative complications, and reducing analgesic consumption. ABSTRACT This clinical narrative review

Risk factors associated with fetal growth restriction in pregnancies complicated by thick placenta

BMC Pregnancy and Childbirth
Background To identify risk factors affecting the occurrence of fetal growth restriction (FGR) in cases of thick placenta. Methods The retrospective study included 128 women who gave birth with a diagnosis of thick placenta between February 2016 to ...

Parkinson's disease under dopamine replacement therapy as a human framework for studying addiction‐relevant mechanisms

Psychiatry and Clinical Neurosciences, EarlyView.
Addiction is a chronic relapsing condition characterized by compulsive reward seeking and impaired behavioral control, associated with major individual and societal burden. Mechanistic investigation in humans remains constrained by ethical limitations, uncontrolled exposure histories, and ecological confounds.

From structural repair to biomechanical compatibility: Aortic stiffness after open and endovascular aortic repair

Experimental Physiology, EarlyView.
Abstract Evaluation of aortic repair has traditionally prioritised perioperative safety, exclusion of the diseased segment and durability. As endovascular treatment expands to younger patients, attention is turning towards the biomechanical compatibility of prosthetic grafts with the native aorta.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

Experimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Attenuation of blood flow pulsatility along the Atlas slope: a physiologic property of the distal vertebral artery?

, 2015
BACKGROUND AND PURPOSE Physiologic and pathologic arterial tortuosity may attenuate blood flow pulsatility. The aim of this prospective study was to assess a potential effect of the curved V3 segment (Atlas slope) of the vertebral artery on arterial flow

Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Changes in autonomic function and cerebral and somatic oxygenation with arterial flow pulsatility for children requiring veno-arterial extracorporeal membrane oxygenation

Brain and Spine
Background: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) carries variability in arterial flow pulsatility (AFP). Research question: What changes in cerebral and somatic oxygenation, hemodynamics, and autonomic function are associated with ...
