Fit Families Program Improves Self-Perception in Children.

OBJECTIVE: To determine the impact of the Fit Families youth weight management program on self-perception of participants. METHODS: Fit Families was delivered through Cooperative Extension and provided education to overweight and obese children and their families on healthful eating and physical activity along with building self-esteem and social competence. At the beginning and end of the 7-week program, a convenience sample of 46 youth completed the Self-Perception Profile for Children questionnaire to evaluate changes in self-perception. RESULTS: Youth had improved self-perception in the areas of athletic competence (P = .04) and physical appearance (P = .007) after participating in Fit Families. CONCLUSIONS AND IMPLICATIONS: Fit Families provides a holistic approach to weight management that promotes positive self-perception, which may decrease the burden of depression, anxiety, and low self-esteem obese youth face.

Landmark control and updating of self-movement cues are largely maintained in head direction cells after lesions of the posterior parietal cortex.

Head direction (HD) cells discharge as a function of the rat's directional orientation with respect to its environment. Because animals with posterior parietal cortex (PPC) lesions exhibit spatial and navigational deficits, and the PPC is indirectly connected to areas containing HD cells, we determined the effects of bilateral PPC lesions on HD cells recorded in the anterodorsal thalamus. HD cells from lesioned animals had similar firing properties compared to controls and their preferred firing directions shifted a corresponding amount following rotation of the major visual landmark. Because animals were not exposed to the visual landmark until after surgical recovery, these results provide evidence that the PPC is not necessary for visual landmark control or the establishment of landmark stability. Further, cells from lesioned animals maintained a stable preferred firing direction when they foraged in the dark and were only slightly less stable than controls when they self-locomoted into a novel enclosure. These findings suggest that PPC does not play a major role in the use of landmark and self-movement cues in updating the HD cell signal, or in its generation.

A randomized trial of home oxygen therapy from the emergency department for acute bronchiolitis.

OBJECTIVE: Hypoxia is a common reason for hospital admission in infants and children with acute bronchiolitis. No study has evaluated discharge from the emergency department (ED) on home oxygen. This study evaluated the feasibility and safety of ED discharge on home oxygen in the treatment of acute bronchiolitis. METHODS: This was a prospective, randomized trial of infants and children with acute bronchiolitis and hypoxia (room-air saturations of < or =87%) aged 2 to 24 months presenting to an urban, academic, tertiary care children's hospital ED from December 1998 to April 2001. Subjects received inpatient admission or home oxygen after an 8-hour observation period in the ED. We measured the failure to meet discharge criteria during the observation period, return for hospital admission, and incidence of serious complications. RESULTS: Ninety-two patients were enrolled. Fifty three (58%) were randomly assigned to home and 39 (42%) to inpatient admission. There were no differences between the groups in age, initial room-air saturation, and respiratory distress severity score. Of 53 patients, 37 (70%) randomly assigned to home oxygen completed the observation period and were discharged from the hospital. The remaining 16 patients were excluded from the study (6), resolved their oxygen requirement (5), or failed to meet the discharge criteria and were admitted (5). One discharged patient (2.7%) returned to the hospital and was admitted for a cyanotic spell at home after the 24-hour follow-up appointment. The patient had an uncomplicated hospital course with a length of stay of 45 hours. The remaining 36 patients (97%) were treated successfully as outpatients with home oxygen. Satisfaction with home oxygen was high from the caregiver and the primary care provider. CONCLUSIONS: Discharge from the ED on home oxygen after a period of observation is an option for patients with acute bronchiolitis. Secondary to the low incidence of complications, the safety of this practice will require a larger study.

Navy Dental Corps: ninety years ... and forward.

The Navy Dental Corps is responsible for ensuring the readiness of America's sailors and marines and optimizing their oral health. This article traces the history from the 1912 Act of Congress authorizing thirty "assistant dental surgeons" as the first Navy Dental Corps through service around the world. Navy dentists have seen service in every war and action in the past ninety years, reaching a peak of seven thousand officers and eleven thousand technicians in World War II. The Navy Dental Corps has served in the Korean and Vietnam Wars, Beirut, Somalia, Haiti, 9/11, Desert Storm, Desert Shield, and Operation Iraqi Freedom.
