Subjective and Performance-Based Cognition and Their Associations with Head Injury History in Older Former National Football League Players.

Purpose: Investigate the association between self-reported subjective and performance-based cognition among older (50-70 years) former professional American football players, as well as the relationship of cognitive measures with concussion history and years of football participation, as a proxy for repetitive head impact exposure.

Methods: Among older former National Football League (NFL) players ( N = 172; mean age = 60.69 ± 5.

Young Children's Screen Time and Physical Activity: Perspectives of Parents and Early Care and Education Center Providers.

Early care and education (ECE) providers and parents can facilitate physical activity (PA) and reduce screen time in preschoolers. Input from caregivers on barriers and facilitators of PA and screen time is needed to comprehensively address these behaviors and promote children's health. Four focus groups (3 parent and 1 ECE provider) were conducted.

Screen-Time Policies and Practices in Early Care and Education Centers in Relationship to Child Physical Activity.

Background: Few preschool children meet physical activity recommendations, whereas the majority exceeds screen-time recommendations. The purpose of this study was to examine the relationship of screen-time policies and practices with children's physical activity and sedentary time in early care and education (ECE) centers.

Methods: We conducted a cross-sectional study of 104 children (3.

State Licensing Regulations on Screen Time in Childcare Centers: An Impetus for Participatory Action Research.

Background: New licensing regulations require Louisiana early care and education centers (ECEs) to limit children's screen time and increase physical activity. A community- academic partnership involving academic, community, government, and ECE stakeholders launched two initiatives: (1) an evaluation of the implementation of licensing regulations at the local level and (2) a statewide effort to develop technical assistance for ECE directors.

Objectives: To describe the methods and lessons learned and to establish recommendations based on this ongoing participatory action research.

Clinical Herpes Zoster in Antarctica as a Model for Spaceflight.

Introduction: Antarctica is a useful analog for spaceflight, as both environments are remote, isolated, and with limited resources. While previous studies have demonstrated increased asymptomatic viral shedding in both the Antarctic and spaceflight environments, clinical manifestations of reactivated viral disease have been less frequently identified. We sought to identify the incidence of clinical herpes zoster from viral reactivation in the Antarctic winter-over population.

Coexpressed D1- and D2-like dopamine receptors antagonistically modulate acetylcholine release in Caenorhabditis elegans.

Dopamine acts through two classes of G protein-coupled receptor (D1-like and D2-like) to modulate neuron activity in the brain. While subtypes of D1- and D2-like receptors are coexpressed in many neurons of the mammalian brain, it is unclear how signaling by these coexpressed receptors interacts to modulate the activity of the neuron in which they are expressed. D1- and D2-like dopamine receptors are also coexpressed in the cholinergic ventral-cord motor neurons of Caenorhabditis elegans.

Mirror syndrome resulting from metastatic congenital neuroblastoma.

Neuroblastoma is a tumor of the sympathetic ganglia and adrenal medulla that rarely metastasizes to the placenta. A 21-year-old gravida 3, para 1 at 28 weeks' gestation had an incidental finding of a 3.8-cm fetal renal mass on prenatal ultrasound.

The 81st Medical Group obstetrics and gynecology flight's role during Hurricane Katrina.

Background: The Obstetrics and Gynecology (OB/GYN) flight at Keesler Medical Center sheltered 36 pregnant women and their families during Hurricane Katrina to ensure that appropriate medical care would be available. Ironically, the hospital's emergency generators were destroyed during the 30-foot storm surge, while one woman with a previous cesarean section went into active labor. She ultimately underwent a cesarean delivery using battery-operated flashlights for illumination.
