Interrater and Intrarater Reliability of the Beighton Score: A Systematic Review.

Background: The Beighton score is commonly used to assess the degree of hypermobility in patients with hypermobility spectrum disorder. Since proper diagnosis and treatment in this challenging patient population require valid, reliable, and responsive clinical assessments such as the Beighton score, studies must properly evaluate efficacy and effectiveness.

Purpose: To succinctly present a systematic review to determine the inter- and intrarater reliability of the Beighton score and the methodological quality of all analyzed studies for use in clinical applications.

Application of three-dimensional printing for pre-operative planning in hip preservation surgery.

Unlabelled: Three-dimensional printing is a valuable modality with broad clinical applications. Hip preservation surgery outcomes are dependent on correction of morphological abnormalities that may be optimally visualized with three-dimensional models. To assess the efficacy of three-dimensional models for patient and trainee education and to determine its benefits during pre-operative planning in hip preservation surgery.

Beta spectrometry with metallic magnetic calorimeters in the framework of the European EMPIR project MetroBeta.

The aim of the European Metrology Research Project MetroBeta is to improve the knowledge of the shapes of beta spectra, both in terms of theoretical calculation and measurement. The precise knowledge of beta spectra is required for the activity standardisation of pure beta emitters. Metallic magnetic calorimeters (MMCs), a type of cryogenic detectors, with the beta emitter embedded in the absorber have proven to be among the best beta spectrometers, in particular for low-energy beta transitions.

Increased Orthopedic Specialization Lowers Costs and Improves Outcomes in Total Joint Arthroplasty.

Background: Total joint arthroplasty (TJA) volumes have risen in the past decade, resulting in increased national spending. Prior studies indicate that TJA performed at higher-volume hospitals result in better patient outcomes at lower costs. The purpose of this study is to determine whether increased orthopedic specialization has similar effects.

The cortisol awakening response in patients remitted from depression.

An impressive number of data has been accumulated on dysfunctions of the hypothalamo-pituitary-adrenal (HPA) axis and cortisol hypersecretion in depression. To assess the dynamic HPA functioning, the cortisol awakening response (CAR) is an easily accessible and reliable approach. Some data suggest that elevated CAR in depressed patients has trait-like characteristics.
