Single-centre results of a randomised controlled trial comparing the Gamma3 nail and a sliding hip screw to treat AO type 31-A1 and 31-A2 trochanteric fractures.

Purpose: The primary goal of this randomised controlled trial was to investigate whether there are differences in the outcome between the Gamma3 nail and a sliding hip screw (SHS) regarding quality of life 1 year after surgery.

Methods: In a controlled randomised trial, we compared the Gamma3 nail (Stryker) and a SHS (Omega, Stryker) in the treatment of 193 patients with pertrochanteric fractures. The follow-up period was 12 months.

Titin governs myocardial passive stiffness with major support from microtubules and actin and the extracellular matrix.

Myocardial passive stiffness is crucial for the heart's pump function and is determined by mechanical elements, including the extracellular matrix and cytoskeletal filaments; however, their individual contributions are controversially discussed and difficult to quantify. In this study, we targeted the cytoskeletal filaments in a mouse model, which enables the specific, acute and complete cleavage of the sarcomeric titin springs. We show in vitro that each cytoskeletal filament's stiffness contribution varies depending on whether the elastic or the viscous forces are considered and on strain level.

Policies and opportunities for physical activity engagement in Austrian schools: a census survey.

Background: Compelling evidence suggests that schools' infrastructure and policy represent potential predictors of health and physical activity (PA) in children and adolescents. However, the translation of these findings into practice has not been examined. This study investigated the activity friendliness of Austrian schools.

Full-fat dairy products and cardiometabolic health outcomes: Does the dairy-fat matrix matter?

Reducing dairy fat intake is a common dietary guideline to limit energy and saturated fatty acid intake for the promotion of cardiometabolic health. However, research utilizing a holistic, food-based approach to assess the consumption of the fat found in dairy, a broad and diverse food group, may provide new insight into these guidelines. Dairy fat is comprised of a diverse assembly of fatty acids, triacylglycerols, sterols, and phospholipids, all uniquely packaged in a milk fat globule.
