Diagnosis and Management of Hand Infections.

Hand and upper-extremity infections span a broad spectrum of presentations for the hand surgeon, primary care provider, and emergency medicine practitioner. As many hand infections arise from penetrating trauma, knowledge of the offending pathogen, location, and mode of spread allows the clinician to determine the appropriate intervention. Along with a thorough history and physical examination, patient factors such as age, occupation, medical comorbidities, and surgical history should be noted.

The Use of Nitinol Staples as Reduction Aids in Fixation of Forearm Diaphyseal Fractures: Surgical Technique and Case Series.

Forearm diaphyseal fractures are common orthopedic injuries that typically require surgical intervention using various implants and approaches. Maintaining reduction while simultaneously achieving compression in radial and/or ulnar shaft fractures during compression plate application can be challenging, particularly with unstable segmental and/or transverse fracture patterns. Nitinol compression staples have become increasingly used as a reduction aid because of their ability to provide continuous compression between the staple legs at the fracture site, low profile, and ease of application.

Controversies and Conundrums in Cardiac Cachexia: Key Questions About Wasting in Patients With HFrEF.

Cardiac cachexia is characterized by unintentional catabolic weight loss, decreased appetite, and inflammation and is common in patients with stage D (advanced) heart failure with reduced ejection fraction (HFrEF). Cardiac cachexia and related muscle-wasting syndromes are markers of, and a consequence of, the heart failure (HF) syndrome. Although many potential modalities for identifying cardiac cachexia exist, the optimal definition, diagnostic tools, and treatment options for cardiac cachexia remain unclear.

Unrecognized volatile and semi-volatile organic compounds from brake wear.

Motor vehicles are among the major sources of pollutants and greenhouse gases in urban areas and a transition to "zero emission vehicles" is underway worldwide. However, emissions associated with brake and tire wear will remain. We show here that previously unrecognized volatile and semi-volatile organic compounds, which have a similarity to biomass burning emissions are emitted during braking.
