Nocturnal Hypoxemic Burden Predicts Mortality in Patients Awaiting Heart Transplantation

Journal of Sleep Research, EarlyView.
Trial design and results on hypoxemic burden in the context of heart transplantation. ABSTRACT Risk stratification for patients with end‐stage heart failure (HF) awaiting heart transplantation (HTX) is crucial. Sleep‐disordered breathing (SDB) is a prevalent comorbidity, yet the impact of its resultant hypoxemic burden remains unclear in this ...

Orthodontic management of uneven gingival margins in patients with healthy or reduced periodontium to improve smile aesthetics

Periodontology 2000, EarlyView.
Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'

Hypogravity simulation using the Variable Gravity Suspension System: A technical report

Experimental Physiology, EarlyView.
Abstract Human movement has evolved within Earth's gravitational environment (1 g; −9.81 m s−2). Future human exploration of terrestrial bodies, including the Moon (0.17 g; −1.62 m s−2) and Mars (0.38 g; −3.71 m s−2), will require astronauts to live and work within reduced gravitational environments (hypogravity).
