Background: We conducted a systematic review of randomized controlled trials (RCTs) to generate more precise estimates of the efficacy and safety of oral versus intravenous antibiotic therapy for S. aureus bacteremia or endocarditis.

Methods: MEDLINE, EMBASE, the Cochrane Library, and Web of Science database were searched through February 21st, 2024.

Urinary tract infections (UTIs) are common complications in people with neurogenic bladder. Prevention, diagnosis, and treatment are challenging for several reasons, including a high prevalence of asymptomatic bacteriuria and catheter use, frequent ambiguous nonlocalizing signs and symptoms, increased risk for complications and difficult-to-treat pathogens, and a lack of effective preventative methods. Current research aims to improve elicitation and evaluation of signs and symptoms, implement algorithms to avoid urine cultures in asymptomatic patients and use appropriate antibiotics for UTI, and identify novel effective prevention methods.

Background: Reversal of direct oral anticoagulants (DOACs) is currently recommended prior to emergent surgery, such as surgical intervention for traumatic geriatric hip fractures. However, reversal methods are expensive and timely, often delaying surgical intervention, which is a predictor of outcomes. The study objective was to examine the effect of DOAC reversal on blood loss and transfusions among geriatric patients with hip fractures.

Background: There is debate on the need to withhold chemical venous thromboembolism (VTE) prophylaxis in patients requiring major orthopedic surgery. We hypothesized that the incidence of clinically significant hemorrhage (CSH) does not differ by the timing of prophylaxis in such patients.

Methods: This was a multicenter, retrospective cohort study conducted at five US trauma centers that included trauma patients admitted between January 1, 2018, to March 1, 2020, requiring surgical fixation of the femoral shaft, hip, or tibia and received VTE chemoprophylaxis during the hospitalization.

Background: Concerns of contracting the highly contagious disease COVID-19 have led to a reluctance in seeking medical attention, which may contribute to delayed hospital arrival among traumatic patients. The study objective was to describe differences in time from injury to arrival for patients with traumatic hip fractures admitted during the pandemic to pre-pandemic patients.

Materials And Methods: This retrospective cohort study at six level I trauma centers included patients with traumatic hip fractures.

Background: Warfarin reversal is typically sought prior to surgery for geriatric hip fractures; however, patients often proceed to surgery with partial warfarin reversal. The effect of partial reversal (defined as having an international normalized ratio [INR] > 1.5) remains unclear.

Objective: Hip fracture surgery in geriatric patients on anticoagulants may increase the risk for blood loss. Anticoagulation reversal may lower these risks; however, data on blood loss and transfusions are limited. The study purpose was to compare outcomes between hip fracture patients 1) not on anticoagulants 2) whose anticoagulants were reversed, and 3) whose anticoagulants were not reversed.

Background: There are multiple reports on the effect of time to surgery for geriatric hip fractures; it remains unclear if earlier intervention is associated with improved mortality, hospital length of stay (HLOS), or cost.

Methods: This was a multi-center retrospective cohort study. Patients (≥65y.

Acute pancreatitis is a well-recognised complication of endoscopic procedures like endoscopic retrograde cholangiopancreatography but not oesophagogastroduodenoscopy (OGD). I report a case of a 33-year-old woman, admitted with severe epigastric pain and vomiting 2 hours after an elective OGD for evaluation of chronic gastrointestinal symptoms. Pancreatitis was diagnosed on the basis of elevated lipase (40 790 U/L; normal 11-82) and findings on imaging studies.
