The Recent Increase in Invasive Bacterial Infections: A Report From the National COVID Cohort Collaborative.

Background: When coronavirus disease 2019 (COVID-19) mitigation efforts waned, viral respiratory infections (VRIs) surged, potentially increasing the risk of postviral invasive bacterial infections (IBIs). We sought to evaluate the change in epidemiology and relationships between specific VRIs and IBIs [complicated pneumonia, complicated sinusitis and invasive group A streptococcus (iGAS)] over time using the National COVID Cohort Collaborative (N3C) dataset.

Methods: We performed a secondary analysis of all prospectively collected pediatric (<19 years old) and adult encounters at 58 N3C institutions, stratified by era: pre-pandemic (January 1, 2018, to February 28, 2020) versus pandemic (March 1, 2020, to June 1, 2023).

Is the Complexity of Arthroscopic Temporomandibular Joint Surgery Associated With Short-Term Complication Rates?

Background: Arthroscopy is regarded as a minimally invasive surgical procedure, with complication rates ranging from 1.7 to 4.4%.

Endoscopic papillectomy versus surgical ampullectomy for adenomas and early cancers of the papilla: a retrospective Pancreas2000/European Pancreatic Club analysis.

Objective: Ampullary neoplastic lesions can be resected by endoscopic papillectomy (EP) or transduodenal surgical ampullectomy (TSA) while pancreaticoduodenectomy is reserved for more advanced lesions. We present the largest retrospective comparative study analysing EP and TSA.

Design: Of all patients in the database, lesions with prior interventions, benign histology advanced malignancy (T2 and more), patients with hereditary syndromes and those undergoing pancreatoduodenectomy were excluded.

Dynamic driving pressure predicts ventilator-induced lung injury in mice with and without endotoxin-induced acute lung injury.

Mechanical ventilation is a necessary lifesaving intervention for patients with Acute Respiratory Distress Syndrome (ARDS) but it can cause ventilator induced lung injury (VILI), which contributes to the high ARDS mortality rate (≈40%). Bedside determination of optimally lung-protective ventilation settings is challenging because the evolution of VILI is not immediately reflected in clinically available, patient-level, data. The goal of this work was therefore to test ventilation waveform-derived parameters that represent the degree of ongoing VILI and can serve as targets for ventilator adjustments.

Coronary Sinus Reducer Improves Angina, Quality of Life, and Coronary Flow Reserve in Microvascular Dysfunction.

Background: Coronary microvascular dysfunction (CMD) is a common cause of angina with no obstructive coronary artery disease (ANOCA), and effective treatment options are limited.

Objectives: This study aims to assess the safety and efficacy of the coronary sinus (CS) Reducer (Neovasc, Inc/Shockwave Medical) for treatment of angina in patients with CMD.

Methods: This Phase II trial enrolled 30 patients with ANOCA, invasively diagnosed CMD, and Canadian Cardiovascular Society (CCS) class 3 to 4 angina despite medical therapy.
