Polysomnographic titration of non-invasive ventilation in motor neurone disease (3TLA): study protocol for a randomised controlled trial.

Background: Non-invasive ventilation (NIV) uses positive pressure to assist people with respiratory muscle weakness or severe respiratory compromise to breathe. Most people use this treatment during sleep when breathing is most susceptible to instability. The benefits of using NIV in motor neurone disease (MND) are well-established.

Return to Play After Arthroscopic Superior Labral Repair: A Systematic Review.

Background: Superior labral tears are common shoulder injuries among athletes, and for athletes undergoing surgical intervention, one of the main priorities is to return to preinjury levels of activity in a timely manner. However, the literature surrounding return to play after superior labral repair presents inconsistent results, with limited studies evaluating the timing of return to play.

Purpose: To systematically review the rate and timing of return to play in athletes after arthroscopic superior labral repair.

Complications of Estimating Hatchery Introgression in the Face of Rapid Divergence: A Case Study in Brook Trout ().

Fish stocking has been utilized for over a century to offset extirpations or declines in abundance of many native species. These historical declines and hatchery contributions have led to uncertainty surrounding whether many contemporary populations are native, introgressed with hatchery sources, or entirely of hatchery origin. Such uncertainty is problematic for the conservation of native biodiversity as it hampers management agencies' ability to prioritize the conservation of indigenous locally adapted populations.

, gen et sp. nov., a small early Permian parareptile with conical teeth from Richards Spur, Oklahoma.

A small, pristinely preserved specimen recently collected from the Dolese Brothers limestone quarry near Richards Spur, Oklahoma provides evidence for the presence of a new early Permian parareptile at this locality. The specimen includes an articulated, nearly complete skull roof, and with the right premaxilla, right quadratojugal, most of the right palate, as well as the right epipterygoid and the sphenethmoid preserved inside. Although similar in many respects to the other contemporary parareptiles , and , it can be distinguished from other acleistorhinids by the presence of a number of autapomorphies related to its dentition.
