Indexed oxygen delivery during pediatric cardiopulmonary bypass is a modifiable risk factor for postoperative acute kidney injury

open access: yesThe Journal of ExtraCorporeal Technology, 2023
Background: Acute kidney injury after pediatric cardiac surgery is a common complication with few established modifiable risk factors. We sought to characterize whether indexed oxygen delivery during cardiopulmonary bypass was associated with ...

Quantitative perfusion and water transport time model from multi b-value diffusion magnetic resonance imaging validated against neutron capture microspheres [PDF]

open access: yes, 2023
Intravoxel Incoherent Motion (IVIM) is a non-contrast magnetic resonance imaging diffusion-based scan that uses a multitude of b-values to measure various speeds of molecular perfusion and diffusion, sidestepping inaccuracy of arterial input functions or bolus kinetics in quantitative imaging. We test a new method of IVIM quantification and compare our

Do continuous forms of intra-operative ultrafiltration enhance recovery after adult cardiac surgery with cardiopulmonary bypass? A protocol for systematic review and meta-analysis of randomized controlled trials

open access: yesSystematic Reviews, 2021
Background Cardiac surgery with cardiopulmonary bypass (CPB) is associated with a systemic inflammatory syndrome that adversely impacts cardiopulmonary function and can contribute to prolonged postoperative recovery.

Facial Thermal and Blood Perfusion Patterns of Human Emotions: Proof-of-Concept [PDF]

open access: yesJournal of Thermal Biology, Vol. 112, 2023, pp. 103464, 2023
In this work, a preliminary study of proof-of-concept was conducted to evaluate the performance of the thermographic and blood perfusion data when emotions of positive and negative valence are applied, where the blood perfusion data are obtained from the thermographic data. The images were obtained for baseline, positive, and negative valence according

Mastering the Best Practices: A Comprehensive Look at the European Guidelines for Cardiopulmonary Bypass in Adult Cardiac Surgery

open access: yesJournal of Cardiovascular Development and Disease, 2023
The successful outcome of a cardiac surgery procedure is significantly dependent on the management of cardiopulmonary bypass (CPB). Even if a cardiac operation is technically well-conducted, a patient may suffer CPB-related complications that could ...

Myocardial Perfusion Imaging After Severe COVID-19 Infection Demonstrates Regional Ischemia Rather Than Global Blood Flow Reduction

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: Acute myocardial damage is common in severe COVID-19. Post-mortem studies have implicated microvascular thrombosis, with cardiovascular magnetic resonance (CMR) demonstrating a high prevalence of myocardial infarction and myocarditis-like ...

A comprehensive mathematical model for cardiac perfusion [PDF]

open access: yesarXiv, 2023
We present a novel mathematical model that simulates myocardial blood perfusion by embedding multiscale and multiphysics features. Our model incorporates cardiac electrophysiology, active and passive mechanics, hemodynamics, reduced valve modeling, and a multicompartment Darcy model of perfusion.

Impact of perfusion ROI detection to the quality of CBV perfusion map [PDF]

open access: yesTechnology Audit and Production Reserves. - 2019. - V. 5, N. 2 (49). - P.4-7, 2019
The object of research in this study is quality of CBV perfusion map, considering detection of perfusion ROI as a key component in processing of dynamic susceptibility contrast magnetic resonance images of a human head. CBV map is generally accepted to be the best among others to evaluate location and size of stroke lesions and angiogenesis of brain ...

Mild hyperthermia enhances sensitivity of gastric cancer cells to chemotherapy through reactive oxygen species–induced autophagic death

open access: yesTumor Biology, 2017
Mild hyperthermia enhances anti-cancer effects of chemotherapy, but the precise biochemical mechanisms involved are not clear. This study was carried out to investigate whether mild hyperthermia sensitizes gastric cancer cells to chemotherapy through ...
