Hip strengthening exercise dosage is not associated with clinical improvements after total hip arthroplasty - a prospective cohort study (the PHETHAS-1 study).

Background: Postoperative rehabilitation exercise is commonly prescribed after total hip arthroplasty (THA), but its efficacy compared to no or minimal rehabilitation exercise has been questioned. Preliminary efficacy would be indicated if a dose-response relationship exists between performed exercise dose and degree of postoperative recovery. The objective was to evaluate the preliminary efficacy of home-based rehabilitation using elastic band exercise on performance-based function after THA, based on the association between performed exercise dose and change in performance-based function (gait speed) from 3 (start of intervention) to 10 weeks (end of intervention) after surgery.

Prospective and External Validation of Machine Learning Models for Short- and Long-Term Mortality in Acutely Admitted Patients Using Blood Tests.

: Predicting mortality in emergency departments (EDs) using machine learning models presents challenges, particularly in balancing simplicity with performance. This study aims to develop models that are both simple and effective for predicting short- and long-term mortality in ED patients. Our approach uses a minimal set of variables derived from one single blood sample obtained at admission.

Correlation between illness perceptions and self-reported degree-of-worry in somatic ill patients in emergency care: a Danish cross-sectional study.

Objectives: The study aimed to investigate the correlation between illness perceptions and self-reported degree-of-worry (DOW) in patients presenting to the emergency department with acute somatic illness.

Design: A cross-sectional survey study collected data from a survey on DOW, the Brief-illness Perception Questionnaire (B-IPQ) and demographics.

Setting: An emergency department at a university hospital in the Capital Region of Denmark.
