Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Transcriptome Profiling Reveals Activation of Inflammation and Apoptosis in the Neonatal Striatum After Deep Hypothermic Circulatory Arrest

, 2019
Objectives: Brain injury, leading to long-term neurodevelopmental deficits, is a major complication in neonates undergoing cardiac surgeries. Because the striatum is one of the most vulnerable brain regions, we used mRNA sequencing to unbiasedly identify

Iatrogenic intramural hematoma of the ascending aorta complicating inadvertent arterial cannulation during central venous catheter placement. A case report and review of the literature

Annals of Cardiac Anaesthesia, 2020
Aortic injury during central venous catheter (CVC) insertion is a rare but serious complication. This presentation describes a case of iatrogenic intramural hematoma of the ascending aorta complicating inadvertent arterial cannulation of the right ...

Surgical treatment of thoracic aortic pseudoaneurysm caused by Brucella melitensis

Journal of Cardiothoracic Surgery, 2023
Thoracic aortic pseudoaneurysm caused by Brucella melitensis is extremely rare with extremely few cases reported to date. Herein, we present the case of a 65 year-old man with a huge pseudoaneurysm of the proximal descending thoracic aorta, involving the

A rare case of vena cava leiomyoma: A case report

Annals of Cardiac Anaesthesia, 2021
Intravascular leiomyoma is an uncommon disease and depending of vascular involvement and anesthetic challenge. We review a case of a 53-year-old woman who underwent vena cava leiomyoma resection under cardiopulmonary bypass using deep hypothermic ...

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Incidence of postoperative seizures in neonates following cardiac surgery with regional cerebral perfusion and deep hypothermic circulatory arrest.

, 2023
OBJECTIVES: Historically, our center has primarily used deep hypothermic circulatory arrest, but in recent years some surgeons have selectively used regional cerebral perfusion as an alternative.

Sutureless aortic valve implantation in patient with porcelain aorta via unclamped aorta and deep hypothermic circulatory arrest

Annals of Cardiac Anaesthesia, 2017
Severe atherosclerotic calcification of the ascending aorta, the so-called porcelain aorta, precludes cardiac surgeons from placing an aortic cross-clamp and direct aortic cannulation due to the increased risk of systemic embolism and stroke.

Contemporary Trends and Risk Factors of Hemodynamic and Myocardial Mechanics Derived by the Pressure Recording Analytical Method After Pediatric Cardiopulmonary Bypass

Frontiers in Cardiovascular Medicine, 2021
Objective: Adverse factors of postoperative hemodynamic and myocardial performance remain largely unexplored in children with congenital heart disease following cardiopulmonary bypass due to technical limitations.

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...
