Transradial retrograde percutaneous coronary intervention of chronic total occlusion using a single guiding catheter: a case report

Journal of Medical Case Reports
Background With the development of specialized equipment and the retrograde technique, success rates for percutaneous coronary intervention of chronic total occlusions have increased from 60 to 90% in the past 10 years.

Comparison of Resistive Index and Volume Flow in Ultrasound of Arteriovenous Fistula for Dialysis Access

Hemodialysis International, EarlyView.
ABSTRACT Introduction Despite extensive investigation, the optimal method of assessing arteriovenous fistula (AV fistula) function remains elusive. Ultrasound is an important tool in the assessment of AV fistula, with a wide range of protocols and flow criteria used across the literature. However, the operator dependency of ultrasound has the potential

Perioperative Transfusion Trigger Score Versus Restrictive Transfusion in Older Non‐Cardiac Surgery Patients: A Multicenter Randomized Controlled Trial

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Restrictive transfusion (Hb < 7 g/dL) is recommended for most perioperative patients, but the optimal threshold for those with cardiovascular disease or Hb 7–10 g/dL remains uncertain. The Perioperative Transfusion Trigger Score (POTTS), which integrates adrenaline requirement, FiO2, temperature, and angina history, may standardize ...

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

Experimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.

Debate: Does the distal radial approach offer added value over the conventional radial approach? No, it does not

REC: Interventional Cardiology (English Ed.)
QUESTION: Are there anatomical reasons to propose distal radial access over conventional radial access? ANSWER: The answer is yes. The hand has 2 arterial arches: a superficial arch, formed by the ulnar artery and the distal radial artery under ...

Acute cardiovascular changes following heat exposure during simulated shipboard firefighting

Experimental Physiology, EarlyView.
Abstract Like structural firefighting, shipboard firefighting requires extreme exertion. However, shipboard firefighting may be a unique cardiovascular stress as most sailors lack extensive firefighting experience and may complete significant work before reaching the fire scene.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...
