Caesarean myomectomy in pregnant women with uterine fibroids.

Rationale: Postpartum haemorrhage, defined as a blood loss of 500 mL or more within 24 hours of birth, is the leading global cause of maternal morbidity and mortality. Uterine fibroids are non-cancerous growths that develop in or around the uterus, and affect an increasing number of women. Caesarean myomectomy is the surgical removal of fibroids during a caesarean section.

Redo Surgical Aortic Valve Replacement versus Valve-in-Valve Transcatheter Aortic Valve Replacement for Degenerated Bioprosthetic Valves.

Background: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) is associated with improved perioperative safety compared to redo surgical aortic valve replacement (redo-SAVR), but long-term outcomes remain uncertain. We therefore compare long-term outcomes of ViV-TAVR and redo-SAVR.

Methods: The study included 1:1 propensity-matched Medicare beneficiaries with degenerated bioprosthetic valves admitted between 09/29/2011 and 12/30/2020 undergoing either redo-SAVR or ViV-TAVR.

Cryo-EM structure and regulation of human NAD kinase.

Reduced nicotinamide adenine dinucleotide phosphate (NADPH) is a crucial reducing cofactor for reductive biosynthesis and protection from oxidative stress. To fulfill their heightened anabolic and reductive power demands, cancer cells must boost their NADPH production. Progrowth and mitogenic protein kinases promote the activity of cytosolic NAD kinase (NADK), which produces NADP, a limiting NADPH precursor.

Association Between Surgeon Stress and Major Surgical Complications.

Importance: Surgeon stress can influence technical and nontechnical skills, but the consequences for patient outcomes remain unknown.

Objective: To investigate whether surgeon physiological stress, as assessed by sympathovagal balance, is associated with postoperative complications.

Design, Setting, And Participants: This multicenter prospective cohort study included 14 surgical departments involving 7 specialties within 4 university hospitals in Lyon, France.

Emergence of an unconventional Enterobacter cloacae-derived Iturin A C-15 as a potential therapeutic agent against methicillin-resistant Staphylococcus aureus.

Antimicrobial resistance poses a significant global health threat by reducing the effectiveness of conventional antibiotics, particularly against pathogens like Methicillin-resistant Staphylococcus aureus (MRSA). This study investigates the antimicrobial potential of rhizospheric soil bacteria from Prosopis cineraria (Sangri) in the Thar Desert. Bacterial strains isolated from these samples were observed to produce secondary metabolites, notably, Iturin A C-15 cyclic lipopeptide (SS1-3-P) which was extracted from strain Enterobacter cloacae SS1-3 and was purified and characterized using reverse-phase HPLC, ESI-LC/MS, Nile-Red Assay, and FT-IR analysis.
