Escherichia coli is of major importance in industrial broiler production as the main cause of salpingitis and peritonitis in broiler breeders. Furthermore E. coli is the most common cause of first week mortality in broiler chickens. The aim of the present study was to investigate the transmission of E. coli, isolated from broiler breeders with salpingitis, to the progeny and the possibility of subsequent first week mortality. Four parent flocks were followed during the whole production period (20-60 weeks) by post mortem and bacteriological examination of randomly selected dead birds. Newly hatched chickens from each flock were swabbed in the cloaca on four occasions (parent age 30, 40, 50, 60 weeks) and E. coli was isolated. Causes of first week mortality were determined pathologically and bacteriologically. E. coli isolates from parents, newly hatched chickens and first week mortality were selected for Pulsed-Field-Gel-Electrophoresis (PFGE) and Multi-Locus-Sequence-Typing (MLST) to determine their clonal relationships. E. coli was the main cause of both salpingitis in parents and first week mortality in broilers, and E. coli dominated the bacterial flora of the cloaca of newly hatched chickens. PFGE of E. coli showed identical band patterns in isolates from the three different sources indicating a transmission of E. coli from parent birds to chickens. In conclusion, E. coli isolated from salpingitis in broiler parents were found to be transmitted to broilers in which some sequence types contributed to the first week mortality.

The first case of esophageal mediastinal fistula after immunotherapy for non-small cell lung cancer: case report and literature review.

Background: Malignant esophageal mediastinal fistula is a severe complication that occurs in both the advanced stages of esophageal cancer and after radiotherapy for esophageal cancer. Esophageal mediastinal fistula is very susceptible to complications such as mediastinitis and mediastinal abscess, resulting in a significantly elevated mortality rate for patients. We reported a rare case of esophageal mediastinal fistula after immunotherapy for non-small cell lung cancer (NSCLC).

Introduction: Cardiovascular disease (CVD) is the leading cause of mortality worldwide, though it may be prevented by increasing physical activity (PA). When behaviour change techniques (BCTs) are bundled together, they increase PA, though which individual BCTs increase PA (and the behavioural mechanism of action (MoA) responsible for said increase) have not been studied. The aim of this study is to conduct a randomised factorial experiment to determine which of four BCTs significantly engage the proposed MoA-self-efficacy for PA-in adults at risk for CVD.

Background: The Adelaide Score is an artificial intelligence system that integrates objective vital signs and laboratory tests to predict likelihood of hospital discharge.
Methods: A prospective implementation trial was conducted at the Lyell McEwin Hospital in South Australia. The Adelaide Score was added to existing human, artificial intelligence, and other technological infrastructure for the first 28 days of April 2024 (intervention), and outcomes were compared using parametric, non-parametric and health economic analyses, to those in the first 28 days of April 2023 (control).
Antibiotic prophylaxis to prevent infection in patients with Child-Pugh A cirrhosis with upper gastrointestinal bleed: an open label randomised controlled trial.

Department of Gastroenterology and Human Nutrition Unit, All India Institute of Medical Sciences, New Delhi, India.
Background And Aims: Although beneficial in reducing the risk of bacterial infections in patients with advanced decompensated cirrhosis after upper gastrointestinal (GI) bleed, the utility of prophylactic antibiotics in those with Child-Pugh A cirrhosis is not known. We studied if prophylactic antibiotics can be withheld in this cohort.
Methods: This was a single-centre, open-label randomised-controlled-trial with non-inferiority design.
Real-world data on utilization of neoadjuvant chemotherapy for muscle invasive bladder cancer: impact on surgical complications and oncological efficacy.
Acta Oncol

Institute of Clinical Medicine, UIT- The Arctic University, Tromsø, Norway; Department of Urology, University Hospital of North Norway, Tromsø, Norway.
Background And Purpose: Recommended treatment of urothelial muscle-invasive bladder cancer (MIBC) is cisplatin-based neoadjuvant chemotherapy (NAC) followed by cystectomy, but there are challenges with low utilization of NAC. We aimed to evaluate the utilization of NAC, perioperative complications and oncological efficacy in a real-world setting.
Patients And Methods: All patients operated with radical cystectomy at the University Hospital of North Norway during 2011-2021 for MIBC were included.
