Vitamin D levels and bone mineral density: a prospective cross-sectional analysis of young orthopedic trauma patients at a rural United States trauma center.

Purpose: The goal of this cross-sectional study was to investigate the prevalence of vitamin D deficiency in young orthopedic trauma patients and its impact on bone mineral density (BMD) measured through computed tomography imaging of the lumbar spine.

Methods: Conducted at a level I trauma center, this prospective cross-sectional analysis included 100 patients aged 18 to 50 years with non-fragility fractures. Vitamin D levels and Hounsfield units of the lumbar spine were recorded from computed tomography scans.

Jets Downstream of Collisionless Shocks: Recent Discoveries and Challenges.

Plasma flows with enhanced dynamic pressure, known as magnetosheath jets, are often found downstream of collisionless shocks. As they propagate through the magnetosheath, they interact with the surrounding plasma, shaping its properties, and potentially becoming geoeffective upon reaching the magnetopause. In recent years (since 2016), new research has produced vital results that have significantly enhanced our understanding on many aspects of jets.

Mapping the dynamics of learning communities about Dutch healthy weight approaches: a causal loop diagram.

Background: Learning communities (LCs) are increasingly used among multidisciplinary public health challenges, such as local healthy weight approaches. LCs aim to stimulate learning, collaboration and actions. Previous research has provided insights into the underlying elements of multidisciplinary LCs, but little is known about the perceived causalities of these elements.

Dietary fructose enhances tumour growth indirectly via interorgan lipid transfer.

Fructose consumption has increased considerably over the past five decades, largely due to the widespread use of high-fructose corn syrup as a sweetener. It has been proposed that fructose promotes the growth of some tumours directly by serving as a fuel. Here we show that fructose supplementation enhances tumour growth in animal models of melanoma, breast cancer and cervical cancer without causing weight gain or insulin resistance.
