Utilization of surgical resources during the USNS COMFORT humanitarian mission to the Americas, June to October 2007.

In 2007, the United States Navy Ship (USNS) COMFORT (T-AH 20), a full-capability medical treatment facility, departed for Partnership for the Americas, her first large-scale humanitarian civic assistance (HCA) mission. Analysis of operational data describes surgical resource utilization. Lessons from previous military humanitarian assistance operations were helpful when placed in the cultural context of Latin America. Premission planning decisions that included time in each port and funding determined the services that were offered to host nations. Surgical, dental, immunizations, preventive medicine, and biomedical repair services had lasting impacts. COMFORT and similar hospital ships are a superior platform to combatant vessels in providing comprehensive surgical care. Medical planning is heavily dependent upon statistics. Collection of additional clinical data on subsequent HCA missions could aid future planning decisions regarding manning, equipment, supplies, and objectives.

Adherence and weight loss outcomes associated with food-exercise diary preference in a military weight management program.

The more consistently someone records their food intake the more likely they are to lose weight. We hypothesized that subjects who kept track via their preferred method would demonstrate higher adherence and therefore improved outcomes compared to those who used a non-preferred method. Participants were randomly assigned to use a paper, PDA, or Web-based diary and classified as "Preferred" if they used their preferred method and "Non-Preferred" if they did not. Days adherent to diary use were collected for 12 weeks. Weight, % body fat, waist circumference, and self-efficacy scores were measured at baseline, 6 and 12 weeks. Thirty nine participants completed the 12 week study. Fifty nine percent were male. The mean age was 35 and mean baseline BMI was 33 kg/m(2) (+/-3.5). Forty four % (n=17) used their "Preferred" diary method and 56% (n=22) did not. Participants who used their preferred diary were more adherent to recording both food intake (64.2% vs. 43.4%, p=.015) and exercise (60.6% vs. 31.2%, p=.001). Though no difference was seen between groups on weight management outcomes, these results suggest that diary preference affects adherence to diary use.
