This study was aimed to determine the rates of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) carriage in a neonatal intensive care unit in a Training and Research Hospital in Ankara, Turkey. A total of 135 newborns were included in the study. Following 5 days stay in intensive care unit, samples were taken from nose and umbilicus for the detection of MRSA and cultivated in mannitol-salt agar and oxacillin-resistance screening agar (ORSAB), respectively. The samples taken from rectum to screen VRE, were placed onto Enterococcosel agar which contained vancomycin and ceftazidime. The confirmation of methicillin resistance in MRSA suspected isolates was performed by oxacillin and cefoxitin disk diffusion tests according to Clinical Laboratory Standards Institute (CLSI) guidelines. Twenty eight (20.7%) of 135 newborns had nasal MRSA carriage, 30 (22.2%) of 135 had umbilical and 10 (7.4%) had both nasal and umbilical MRSA carriage. No rectal VRE carriage was found among the newborns. As a result, we suggest that periodical MRSA and VRE carriage investigation in the patients hospitalized in neonatal intensive care units is of outmost help to control and prevent nosocomial infections.

Department of Anesthesiology, The Third Affiliated Hospital of Sun Yat-sen University, Guangzhou, China.
Background: Patients undergoing liver transplantation (LT) are at risk of perioperative neurocognitive dysfunction (PND), which significantly affects the patients' prognosis.
Objective: This study used machine learning (ML) algorithms with an aim to extract critical predictors and develop an ML model to predict PND among LT recipients.
Methods: In this retrospective study, data from 958 patients who underwent LT between January 2015 and January 2020 were extracted from the Third Affiliated Hospital of Sun Yat-sen University.
Artificial Intelligence-Guided Lung Ultrasound by Nonexperts.
JAMA Cardiol
January 2025
Department of Emergency Medicine, Rush University Medical Center, Chicago, Illinois.
Importance: Lung ultrasound (LUS) aids in the diagnosis of patients with dyspnea, including those with cardiogenic pulmonary edema, but requires technical proficiency for image acquisition. Previous research has demonstrated the effectiveness of artificial intelligence (AI) in guiding novice users to acquire high-quality cardiac ultrasound images, suggesting its potential for broader use in LUS.
Objective: To evaluate the ability of AI to guide acquisition of diagnostic-quality LUS images by trained health care professionals (THCPs).

Center for Surgery and Public Health, Department of Surgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.
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.
Safety and Efficacy of Tranexamic Acid in General Surgery.

January 2025
Population Health Research Institute, Hamilton, Ontario, Canada.
Importance: Perioperative bleeding is common in general surgery. The POISE-3 (Perioperative Ischemic Evaluation-3) trial demonstrated efficacy of prophylactic tranexamic acid (TXA) compared with placebo in preventing major bleeding without increasing vascular outcomes in noncardiac surgery.
Objective: To determine the safety and efficacy of prophylactic TXA, specifically in general surgery.
