Influence of Practitioner Dashboard Feedback on Anesthetic Greenhouse Gas Emissions: A Prospective Performance Improvement Investigation.

Anesthetic gases contribute to global warming. We described a two-year performance improvement project to examine the association of individualized provider dashboard feedback of anesthetic gas carbon dioxide equivalent (CDE) production and median perioperative fresh gas flows (FGF) during general anesthetics during perioperative management. Using a custom structured query language (SQL) query, hourly CDE for each anesthetic gas and median FGF were determined.

Transcatheter versus Surgical Aortic Valve Replacement in Patients Younger than 65 Years in the US.

Objective: To characterize trends and outcomes of aortic valve replacement in patients <65 with aortic stenosis between 2013 and 2021.

Methods: This retrospective analysis included 9,557 patients who underwent biological aortic valve replacement in California, New York, and New Jersey from 2013 through 2021. Patients were stratified by approach: transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR).

Obesity and postpartum hospital use among individuals without additional medical comorbidities.

Objective: The objective of this study was to examine whether obesity without preexisting or gestational comorbidities is associated with postpartum hospital use (PHU).

Methods: We studied 2016 to 2018 birth certificate and discharge data on 178,729 New York City births without International Classification of Diseases, Tenth Revision (ICD-10) codes at delivery for diabetes; hypertension; placental disease; anemia; thyrotoxicosis; bariatric surgery; and pulmonary, cardiac, renal, bleeding, autoimmune, digestive, neuromuscular, mental, or substance-use disorders. We defined PHU as ≥1 readmission or emergency department visit within 30 days of delivery discharge.

Non-conventional toxin WTX and its disulfide-fixed synthetic fragments: Interaction with nicotinic acetylcholine receptors and reduction of blood pressure.

Non-conventional snake venom toxins, such as WTX from the cobra Naja kaouthia, are three-finger proteins containing a fifth disulfide bond in the N-terminal polypeptide loop I and inhibiting α7 and muscle-type nicotinic acetylcholine receptors (nAChRs). Because the central polypeptide loop II of non-conventional toxins plays an important role in their biological activity, we synthesized several WTX loop II fragments with two cysteine residues added at the N- and C-termini and oxidized to form a disulfide bond. The inhibition by peptides of several nAChRs subtypes was investigated using different methods and the effects of peptides on the rat arterial pressure and heart rate were analyzed.

Opioid administration across racial and ethnic groups for patients undergoing liver resection: are there disparities?

Background: Racial and ethnic disparities in the treatment of perioperative pain have not been well-studied, despite being observed in a variety of other medical settings. The goal of this investigation was to evaluate the relationship between race and ethnicity and intra- and postoperative opioid administration for patients undergoing open liver resection surgery.

Methods: In this single-center retrospective cohort study, adult patients undergoing open liver resection from January 2012 to May 2019 were identified.
