Mind the gap: pre-operative diastasis recti increases trocar site hernia risk after laparoscopic cholecystectomy.

Purpose: Trocar site hernias impact 1-10% of patients undergoing a laparoscopic cholecystectomy, typically at the 10 mm port site. Risk factors identified for trocar site hernias include obesity and age; however, little is known about the impact of pre-existing diastasis rectus abdominus (DRA) on trocar site hernia rates. Therefore, we aimed to determine the impact of pre-operative DRA on trocar site hernia rates after laparoscopic cholecystectomy.

Robotic vs. minimally invasive mitral valve repair: A 5-year comparison of surgical outcomes.

Background: Minimally invasive mitral valve repair (MVr) is commonly performed. Data on the outcomes of robotic MVr versus nonrobotic minimally invasive MVr are lacking. We sought to compare the short-term and mid-term outcomes of robotic and nonrobotic MVr.

Mitral valve surgery after failed transcatheter edge-to-edge repair.

Objective: Mitral valve operations for failed transcatheter edge-to-edge repair (TEER) are increasing. This study investigated the indications, surgical procedures, and outcomes after surgery for failed TEER.

Methods: We analyzed records of patients who underwent mitral valve operations after TEER between January 2013 and September 2021.

Outcomes and Principles of Patient Selection for Laser Interstitial Thermal Therapy for Metastatic Brain Tumor Management: A Multisite Institutional Case Series.

Background: Laser interstitial thermal therapy (LITT) is an emerging treatment modality for both primary brain tumors and metastases. We report initial outcomes after LITT for metastatic brain tumors across 3 sites at our institution and discuss potential strategies for optimal patient selection and outcomes.

Methods: International Classification of Diseases, Ninth Revision and Tenth Revision codes were used to identify patients with malignant brain tumors treated via LITT across all 3 Mayo Clinic sites with at least 6 months follow-up.

Management strategies for pediatric patients with tectal gliomas: a systematic review.

Pediatric tectal gliomas generally have a benign clinical course with the majority of these observed radiologically. However, patients often need treatment for obstructive hydrocephalus and occasionally require cytotoxic therapy. Given the lack of level I data, there is a need to further characterize management strategies for these rare tumors.

Particulate Respirators Functionalized with Silver Nanoparticles Showed Excellent Real-Time Antimicrobial Effects against Pathogens.

Particulate respirators designed to filtrate fine particulate matters usually do not possess antimicrobial functions. The current study aimed to functionalize particulate respirators with silver nanoparticles (nanosilver or AgNPs), which have excellent antimicrobial activities, utilizing a straightforward and effective method. We first enhanced the nanosilver-coating ability of nonwoven fabrics from a particulate respirator through surface modification by sodium oleate.

Characterization of extracellular polymeric substances in the biofilms of typical bacteria by the sulfur K-edge XANES spectroscopy.

A combined approach of physicochemical extraction and sulfur K-edge X-ray absorption near-edge structure (XANES) spectroscopy was applied to characterize the extracellular polymeric substances (EPS) of typical bacterial biofilms in this study. Physicochemical analysis showed variation of the contents of DNA, polysaccharide and protein in different fractions of EPS in different mediums. The sulfur K-edge XANES analysis yielded a variety of spectra.
