Treatment of Initial Anterior Shoulder Instability in National Hockey League Players: A Survey of NHL Team Physicians.

Background: Managing an in-season anterior shoulder instability poses a special challenge for team physicians, as they need to balance the aim of promptly returning the athlete to play while mitigating the chances of recurrence and further injury to the shoulder.

Purpose: To investigate and report on the treatment preferences of National Hockey League (NHL) team physicians when managing in-season first-time anterior shoulder instability in professional hockey players.

Study Design: Cross-sectional study.

Mental Health Service Utilization among Adults with Head Injury with Loss of Consciousness: Implications for Social Work.

The purpose of this study was to identify factors associated with mental health service utilization among adults with head injury with loss of consciousness (LOC) using Andersen's model of health. This secondary data analysis used the 2011-2014 National Health and Nutrition Examination Survey with data collected from 7,399 adults. Binary logistic regression was conducted to determine odds associated with predisposing, enabling, and needs factors on head injury with LOC and mental health service utilization.

The Power of Perception: Lived Experiences with Diagnostic Labeling in Mental Health Recovery without Ongoing Medication Use.

The recovery movement in mental health emphasizes holistic and individualized treatment through many pathways to recovery, though the majority of mental health treatment and existing literature emphasize pharmacotherapy and medication adherence for major mental health conditions. The reimbursement system and research literature are oriented around formal diagnostic categories based in a biomedical perspective of mental health problems, but diagnostic labels also carry stigma and influence how clients perceive themselves and their mental health problems. To investigate the influence of labeling and perception in alternate pathways to recovery, this qualitative study explores the lived experience of diagnostic labeling and self-perception among persons in sustained recovery without ongoing medication use.

A 20 m wide-field diffraction-limited telescope.

A 20 m space telescope is described with an unvignetted 1° field of view-a hundred times larger in area than fields of existing space telescopes. Its diffraction-limited images are a hundred times sharper than from wide-field ground-based telescopes and extend over much if not all the field, 40 arcmin diameter at 500 nm wavelength, for example. The optical system yielding a 1°, 1.

6.5 m telescope for multi-object spectroscopy over a 3° field of view.

Multi-object spectroscopy via independently positioned optical fibers is of growing importance in many research areas in astronomy. Currently the most powerful instrument of this type is the Dark Energy Spectroscopic Instrument (DESI), now being commissioned at the 3.8 m Mayall telescope.
