Recent evidence demonstrates that closed chest compressions directly over the left ventricle (LV) in a traumatic cardiac arrest (TCA) model improve hemodynamics and return of spontaneous circulation (ROSC) when compared with traditional compressions. Resuscitative endovascular balloon occlusion of the aorta (REBOA) also improves hemodynamics and controls hemorrhage in TCA. We hypothesized that chest compressions located over the LV would result in improved hemodynamics and ROSC in a swine model of TCA using REBOA. ⋯ There was no difference in ROSC between LV and traditional compressions when REBOA was used in this swine model of TCA. REBOA conferred a survival benefit regardless of compression location.

This study aims to assess multimodal pain management and opioid prescribing practices in patients undergoing breast surgery. ⋯ There is need for a multidisciplinary approach to pain management with the use of enhanced recovery after surgery protocols as potential means to standardize perioperative regimens and mitigate opioid overprescription.

Narrow- versus Broad-Spectrum Antibiotics for Simple Acute Appendicitis Treated by Appendectomy: A Post Hoc Analysis of EAST MUSTANG Study.
We sought to compare the effectiveness of narrow- versus broad-spectrum antibiotics (abx) in preventing infectious complications in adults with acute appendicitis treated with appendectomy. ⋯ Significant practice variation in duration and spectrum of antibiotic adjunct for surgical treatment of simple acute appendicitis treatment is evident, and broad-spectrum abx did not offer clinical advantages over narrow-spectrum abx. Restriction of antibiotic spectrum should be considered, although randomized trials are required to overcome selection bias.

The use of mesenchymal stem cells (MSCs) for treatment during ischemia is novel. Hydrogen sulfide (H2S) is an important paracrine mediator that is released from MSCs to facilitate angiogenesis and vasodilation. Three enzymes, cystathionine-beta-synthase (CBS), cystathionine-gamma-lyase (CSE), and 3-mercaptopyruvate-sulfurtransferase (MPST), are mainly responsible for H2S production. However, it is unclear how these enzymes impact the production of other critical growth factors and chemokines. We hypothesized that the enzymes responsible for H2S production in human MSCs would also critically regulate other growth factors and chemokines. ⋯ The enzymes that produce H2S in MSCs are also responsible for the production of other stem cell paracrine mediators under stressful stimuli. Therefore, reprogramming MSCs to endogenously produce more H2S as a therapeutic intervention could also critically impact other paracrine mediators, which may alter the desired beneficial effects.
