Retinal and Choroidal Circulation Impairments in Fanconi Anemia.
Am J Ophthalmol
January 2025
Hacettepe University School of Medicine, Department of Ophthalmology, Ankara, Turkey.
Objective: To evaluate the effects of Fanconi anemia (FA) on retinal and choroidal microvasculature using Optical Coherence Tomography (OCT) and Optical Coherence Tomography Angiography (OCTA).
Design: Cohort study with age-matched controls.
Subjects And Participants: This study included 11 eyes from 11 patients diagnosed with FA and 12 eyes from 12 age-matched healthy controls.
Background: Although revascularization is first-line therapy for chronic limb-threatening ischemia (CLTI), there are no established treatments for patients in whom revascularization is not (or is a poor) option, including CLTI that has responded poorly to revascularization. This study verified the efficacy of the Rheocarna, a novel apheresis device, for no-option CLTI or poor-response CLTI after revascularization.
Methods And Results: This multicenter retrospective observational study analyzed 221 patients (221 limbs) with no- or poor-option CLTI (mean [±SD] age 71±10 years; males, 70.
Physiological arterial pressure improves renal performance during normothermic machine perfusion in a porcine kidney DCD model.
Heliyon
January 2025
Division of HPB and Transplant Surgery, Department of Surgery, Transplant Institute, Erasmus Medical Center, Rotterdam, the Netherlands.
Background: Normothermic machine perfusion (NMP) provides a platform for kidney quality assessment. Donation after circulatory death (DCD) donor kidneys are associated with great ischemic injury and high intrarenal resistance (IRR). This experimental study aims to investigate the impact of different perfusion pressures on marginal kidney function and injury during NMP.

Arterial spin labelling (ASL) enables non-invasive quantification of regional brain perfusion using MRI. ASL was used in the Reducing Pathology in Alzheimer's Disease through Angiotensin TaRgeting (RADAR) multi-centre trial to pilot the assessment of the effects of the anti-hypertension drug losartan on cerebral blood flow (CBF). In the multi-centre setting, disparities in ASL implementation on scanners from different manufacturers lead to inherent differences in measured CBF and its associated parameters (e.

Introduction: Tumor tissues exhibit significantly lower oxygen partial pressure compared to normal tissues, leading to hypoxia in the tumor microenvironment and result in resistance to tumor treatments. Strategies to mitigate hypoxia include enhancing blood perfusion and oxygen supply, for example,by decomposing hydrogen peroxide within the tumor. Improving hypoxia in the tumor microenvironment could potentially improve the efficacy of cancer treatments.
