The period directly following surgery is critical for patients as they are at risk of infections and other types of complications, often summarized as severe adverse events (SAE). We hypothesize that impending complications might alter the circadian rhythm and, therefore, be detectable during the night before. We propose a SMOTE-enhanced XGBoost prediction model that classifies nighttime vital signs depending on whether they precede a serious adverse event or come from a patient that does not have a complication at all, based on data from 450 postoperative patients. The approach showed respectable results, producing a ROC-AUC score of 0.65 and an accuracy of 0.75. These findings demonstrate the need for further investigation.

Infection with Neisseria gonorrhoeae, the causative agent of gonorrhoea, causes significant morbidity worldwide and can have long-term impacts on reproductive health. The greatest global burden of gonorrhoea occurs in low- and middle-income settings. Global public health significance is increasing due to rising antimicrobial resistance (AMR), which threatens future gonorrhoea management.

Headache
January 2025
Department of Clinical Neurosciences, Cumming School of Medicine, University of Calgary, Calgary, Alberta, Canada.
Objective: Our primary objective was to evaluate the safety and feasibility of transcranial direct current stimulation combined with exercise therapy for the treatment of cervicogenic headache. Our exploratory objectives compared symptoms of headache, mood, pain, and quality of life between active and sham transcranial direct stimulation combined with exercise therapy.
Background: Cervicogenic headache arises from injury to the cervical spine or degenerative diseases impacting cervical spine structure resulting in pain, reduced quality of life, and impaired function.

Hum Resour Health
January 2025
Wolfson Institute of Population Health, Queen Mary University of London, Charterhouse Square, London, EC1M 6BQ, UK.
Background: Health systems across Europe are facing a workforce crisis, with some experiencing severe shortages of doctors.

Case Presentation: In the early 2000s the United Kingdom created a new occupational role, that of physician assistant.
