Incarcerated Left Paraduodenal Hernia as a Rare Cause of Acute Abdomen: A Case Report and Literature Review.

Internal hernias are one of the rare causes of intestinal obstruction and usually is the diagnosis of exclusion. Para-duodenal hernias (PDH) are rare congenital disorders that occur due to malrotation of the midgut in the embryonic phase of development. They can be asymptomatic or can present as an incarcerated, strangulated, or even obstructed internal hernia.

Endocytic recycling is central to circadian collagen fibrillogenesis and disrupted in fibrosis.

Collagen-I fibrillogenesis is crucial to health and development, where dysregulation is a hallmark of fibroproliferative diseases. Here, we show that collagen-I fibril assembly required a functional endocytic system that recycles collagen-I to assemble new fibrils. Endogenous collagen production was not required for fibrillogenesis if exogenous collagen was available, but the circadian-regulated vacuolar protein sorting (VPS) 33b and collagen-binding integrin α11 subunit were crucial to fibrillogenesis.

Laparoscopic Repair of Duodenal Perforation Using the Falciform Ligament: A Cross-Sectional Study.

Background Duodenal perforation is a life-threatening condition. Laparoscopic repair using the falciform ligament is a minimally invasive technique that has shown promising results. We present a case series of patients who underwent laparoscopic repair of duodenal perforation using the falciform ligament as an alternative to conventional techniques.

Shorter Premature Atrial Complex Coupling Interval Leads to Mechanical Dysfunction, Fibrosis, and AF in Swine.

Background: We have previously shown that dyssynchronous premature atrial complexes (PACs) from the lateral left atrium (LA) lead to greater atrial mechanical dysfunction, remodeling, and sustained atrial fibrillation (AF) than synchronous PACs from the interatrial septum. However, the impact of PAC coupling interval (CI) on atrial remodeling is unclear.

Objectives: This study sought to explore the effect of PAC CI on atrial mechanics and remodeling in the swine model.

Autonomic Effects of Pulsed Field vs Thermal Ablation for Treating Atrial Fibrillation: Subanalysis of ADVENT.

Background: Autonomic denervation is an ancillary phenomenon during thermal ablation of atrial fibrillation (AF), that may have synergistic effects on symptomatic improvement and long-term freedom from AF. Pulsed field ablation (PFA), a nonthermal ablation modality, was noninferior to thermal ablation in treating AF; however, PFA's relative myocardial selectivity may minimize autonomic effects.

Objectives: This study sought to compare heart rate (HR) and heart rate variability (HRV) metrics as markers of autonomic function after ablation using PFA vs thermal ablation.
