Aortic pseudoaneurysm is a rare, life-threatening complication after cardiac or aortic surgery. In this article, we report reoperation on an 86-year-old man undergoing total arch replacement and omentoplasty for an infectious aortic aneurysm, 5 years previously. He was transferred to our hospital and fell into shock. Prompt drainage of the right-side pleural cavity manifested 2000 ml of blood. Computed tomography revealed contrast extravasation into a pseudoaneurysm, which arose from the proximal anastomotic site of the ascending aorta. The patient underwent emergent surgery that included an extremely careful dissection of the omentum and pericardial adherences, through the re-sternotomy. The patient recovered without neurological sequelae.

Factors Associated with Low/Moderate Perceived Risk for HIV Acquisition Among Gay, Bisexual, and Other Men Who Have Sex with Men Eligible to Use Pre-exposure Prophylaxis from Brazil, Mexico, and Peru.

Perceived risk for HIV acquisition among gay, bisexual, and other men who have sex with men (GBMSM) may not align with their actual sexual HIV exposure. Factors associated with low/moderate perceived risk among GBMSM eligible for pre-exposure prophylaxis (PrEP) (based on their high estimated HIV exposure) have been poorly described in Latin America. This is a secondary analysis of a 2018 web-based cross-sectional survey in Brazil, Mexico, and Peru.

Purpose: To comprehensively compare the diagnostic ability and inter-reader agreement of magnetic resonance imaging (MRI) findings for predicting massive hemorrhage after cesarean section in patients with placental malposition, aiming to identify the most reliable and objective indicators.
Methods: Totally, 148 consecutive patients with placental malposition underwent MRI and cesarean section at our hospital between January 2014 and July 2021. The patients were divided into massive and non-massive hemorrhage groups.

Purpose: To quantify the separation between maternal blood cell-free (cf)DNA markers in preeclampsia and unaffected pregnancies and compare with existing markers. This approach has not been used in previous studies.
Methods: Comprehensive systematic literature search of PubMed to identify studies measuring total cfDNA, fetal cf(f)DNA or the fetal fraction (FF) in pregnant women.
Clinical value of aortic arch morphology in transfemoral TAVR: artificial intelligence evaluation.

Department of Cardiovascular Surgery, Xijing Hospital, Xi'an, Shaanxi, China.
Background: The impact of aortic arch (AA) morphology on the management of the procedural details and the clinical outcomes of the transfemoral artery (TF)-transcatheter aortic valve replacement (TAVR) has not been evaluated. The goal of this study was to evaluate the AA morphology of patients who had TF-TAVR using an artificial intelligence algorithm and then to evaluate its predictive value for clinical outcomes.
Materials And Methods: A total of 1480 consecutive patients undergoing TF-TAVR using a new-generation transcatheter heart valve at 12 institutes were included in this retrospective study.

Herbicides such as paraquat (PQ) are frequently utilized particularly in developing nations. The present research concentrated on the pulmonary lesions triggered by PQ and the beneficial effect of the angiotensin receptor neprilysin inhibitor (ARNI), sacubitril/valsartan, against such pulmonary damage. Five groups of rats were established: control, ARNI, PQ (10 mg/kg), ARNI 68 + PQ, and ARNI 34 + PQ.
