Abdominal and intra-abdominal fibromatoses: Outcomes over time.

Objectives: Abdominal wall and intra-abdominal fibromatoses are locally aggressive, nonmetastasizing neoplasms. Surgery has been the mainstay of local control, but new forms of therapy have been developed that may influence the clinical course and morbidity. We studied the clinical features and outcomes of patients with abdominal and intra-abdominal fibromatoses over time.

Remote Ischemic Preconditioning Attenuates Ischemia-Reperfusion Injury Induced Reductions in Vascular Function through Release of Endogenous Opioids.

Remote Ischemic Preconditioning (RIPC) is a therapy characterized by repeated bouts of limb ischemia and reperfusion. RIPC protects against ischemia-reperfusion injury (IRI), and preclinical studies suggest that this is mediated through release of endogenous opioids. We aimed to interrogate the role of endogenous opioids in RIPC-signaling in humans, using an arm model of IRI.

Dysregulated autoantibodies targeting AGTR1 are associated with the accumulation of COVID-19 symptoms.

Coronavirus disease 2019 (COVID-19) presents a wide spectrum of symptoms, the causes of which remain poorly understood. This study explored the associations between autoantibodies (AABs), particularly those targeting G protein-coupled receptors (GPCRs) and renin‒angiotensin system (RAS) molecules, and the clinical manifestations of COVID-19. Using a cross-sectional analysis of 244 individuals, we applied multivariate analysis of variance, principal component analysis, and multinomial regression to examine the relationships between AAB levels and key symptoms.

Apolipoprotein-L1 G1 variant contributes to hydrocephalus but not to atherosclerosis in apolipoprotein-E knock-out mice.

Introduction: In USA, six million individuals with Sub-Saharan ancestry carry two high-risk variants, which increase the risk for kidney diseases. Whether APOL1 high-risk variants are independent risk factors for cardiovascular diseases is unclear and requires further investigation.

Methods: We characterized a mouse model to investigate the role of APOL1 in dyslipidemia and cardiovascular diseases.

Preeclampsia in mice carrying fetuses with APOL1 risk variants.

African-American women have a maternal mortality rate approximately three times higher than European-American women. This is partially due to hypertensive disorders of pregnancy, including preeclampsia. Fetal high-risk genotype increases preeclampsia risk, although mechanisms remain elusive.
