•Our study did not support the hypothesis that small AVMs lead to larger hematoma volumes in the event of a rupture.•AVM size did not correlate with the clinical severity of the bleeding as measured with HH and WFNS scores.•Larger supratentorial hematomas were associated with a more severe clinical manifestation and a poorer outcome.•In the event of a rupture, the AVM size did not correlate with the 2-4-month GOS.•AVICH score showed a good correlation with the 2-4-month GOS score.

Predictive analytics has emerged as a promising approach for improving reproductive health care and patient outcomes. During pregnancy and birth, the ability to accurately predict risks and complications could enable earlier interventions and reduce adverse events. However, there are challenges and ethical considerations for implementing predictive models in perinatal care settings.

Melatonin stabilizes atherosclerotic plaques: an association that should be clinically exploited.

Front Med (Lausanne)

December 2024

CENECON, Faculty of Medical Sciences, Universidad de Buenos Aires, and Pontificia Universidad Catolica Argentina, Buenos Aires, Argentina.

Atherosclerosis is the underlying factor in the premature death of millions of humans annually. The cause of death is often a result of the rupture of an atherosclerotic plaque followed by the discharge of the associated molecular debris into the vessel lumen which occludes the artery leading to ischemia of downstream tissue and to morbidity or mortality of the individual. This is most serious when it occurs in the heart (heart attack) or brain (stroke).

Background: Endoscopic bariatric interventions are viable alternatives to traditional weight loss surgeries for patients with a body mass index between 30 and 40 kg/m. While studies have explored the impact of intragastric balloons on obesity and weight reduction, comprehensive data on real-world device-related complications and failures are limited. This study aimed to investigate mechanical failures leading to patient adverse events reported to the US Food and Drug Administration.

Aortic dissection is the most common thoracic aortic emergency and is associated with significant morbidity and mortality. Initial complications are dependent on reduction of sheer stress against the aortic wall to protect against rupture and minimize progression of the aortic wall injury. In patients with dissection starting at or distal to the left subclavian artery (Stanford type B), initial management includes strict blood pressure and heart rate control with monitoring for any complications such as malperfusion, rupture or hemodynamic instability.

Dimethyl fumarate is repurposed to ameliorate aortic aneurysm and dissection in mice.

Eur J Pharmacol

December 2024

Department of Pharmacology, Xiangya School of Pharmaceutical Sciences, Central South University, Changsha, 410078, Hunan, China; Hunan Provincial Key Laboratory of Cardiovascular Research, Central South University, Changsha, 410078, Hunan, China. Electronic address:

Aortic aneurysm and dissection pose fatal threats but no effective drug therapies are available. Previous work has been directed to reduce risk factors or target key pathological events, but none of the translational efforts succeeds. Here, we attempt to repurpose dimethyl fumarate (DMF), an FDA-approved immunomodulatory drug for multiple sclerosis, for the treatment of aortic aneurysm and dissection.
