Genetic pleiotropy between mood disorders, metabolic, and endocrine traits in a multigenerational pedigree.

Bipolar disorder (BD) is a mental disorder characterized by alternating periods of depression and mania. Individuals with BD have higher levels of early mortality than the general population, and a substantial proportion of this is due to increased risk for comorbid diseases. To identify the molecular events that underlie BD and related medical comorbidities, we generated imputed whole-genome sequence data using a population-specific reference panel for an extended multigenerational Old Order Amish pedigree (n = 394), segregating BD and related disorders.

An Analysis of Beta-Blocker Administration Pre-and Post-Traumatic Brain Injury with Subanalyses for Head Injury Severity and Myocardial Injury.

A growing body of literature indicates that beta-blocker administration after traumatic brain injury (TBI) is cerebroprotective, limiting secondary injury; however, the effects of preinjury beta blocker status remain poorly understood. We sought to characterize the effects of pre- and postinjury beta-blocker administration on mortality with subanalyses accounting for head injury severity and myocardial injury. In a Level II trauma center, all admissions of patients ≥18 years with a head Abbreviated Injury Scale Score ≥2, Glasgow Coma Scale ≤13 from May 2011 to May 2013 were queried.

An analysis of neurosurgical practice patterns and outcomes for serious to critical traumatic brain injuries in a mature trauma state.

Background: We sought to characterize trends in neurosurgical practice patterns and outcomes for serious to critical traumatic brain injuries from 2003 to 2013 in the mature trauma state of Pennsylvania.

Methods: All 2003 to 2013 admissions to Pennsylvania's 30 accredited Level I to II trauma centers with serious to critical traumatic brain injuries (head Abbreviated Injury Scale [AIS] score ≥ 3, Glasgow Coma Scale [GCS] score < 13) were extracted from the state registry. Adjusted temporal trend tests controlling for demographic and injury severity covariates assessed the impact of admission year on intervention rates (craniotomy, craniectomy, and intracranial pressure monitor/ventriculostomy [ICP]) and outcome measures for the total population as well as serious (head AIS score ≥ 3; GCS score, 9-12) and critical (head AIS score ≥ 3, GCS score ≤ 8) subgroups.

An analysis of Brain Trauma Foundation traumatic brain injury guideline compliance and patient outcome.

Introduction: Evidence-based guidelines for the care of severe traumatic brain injury have been available from the Brain Trauma Foundation (BTF) since 1995. A total of 15 recommendations compose the current guidelines. Although each individual guideline has been validated in isolation, to date, little research has examined the guidelines in composite.
