RESUMEN
BACKGROUND: Obesity is a public health problem in Micronesia. The objective of the study was to assess obesity, the relationship between body mass index (BMI) and body fat percentage (BF%) among adults, and determine the appropriate BMI cut-points in Kiribati. METHODS: A cross-sectional study was undertaken among 483 adults randomly selected from South Tarawa (ST) and Butaritari (BT). Weight, height, BF% and physical activity level (PAL) was measured using standard methods. Linear and quadratic regression analyses were conducted to assess the association between BF% and BMI whilst controlling for age and gender. Receiver operating characteristics (ROC) curve analyses were used to assess whether for the Kiribati population alternative BMI cut-off points for obesity are needed. RESULTS: Approximately 75% of participants were obese using standard BMI and BF% cut-offs, with the highest prevalence observed in South Tarawa. BF% was significantly (p < 0.001) and positively associated with age (males, r = 0.78; females, r = 0.67; p < 0.001) and BMI. Based on ROC-curve analyses the BMI cut-offs for predicting high BF% among I-Kiribati people were 24.5 kg/m2 for males and 32.9 kg/m2 for females. CONCLUSIONS: In conclusion, the majority of adults in Kiribati were either obese or overweight and had high BF%. We suggest that ethnic-specific BMI cut-points to define obesity for the population of Kiribati may be more appropriate than the currently used international cut-points.

OBJECTIVE: To characterize the multiple dimensions and benefits of the Mediterranean diet as a sustainable diet, in order to revitalize this intangible food heritage at the country level; and to develop a multidimensional framework - the Med Diet 4.0 - in which four sustainability benefits of the Mediterranean diet are presented in parallel: major health and nutrition benefits, low environmental impacts and richness in biodiversity, high sociocultural food values, and positive local economic returns. DESIGN: A narrative review was applied at the country level to highlight the multiple sustainable benefits of the Mediterranean diet into a single multidimensional framework: the Med Diet 4.0. Setting/subjects We included studies published in English in peer-reviewed journals that contained data on the characterization of sustainable diets and of the Mediterranean diet. The methodological framework approach was finalized through a series of meetings, workshops and conferences where the framework was presented, discussed and ultimately refined. RESULTS: The Med Diet 4.0 provides a conceptual multidimensional framework to characterize the Mediterranean diet as a sustainable diet model, by applying principles of sustainability to the Mediterranean diet. CONCLUSIONS: By providing a broader understanding of the many sustainable benefits of the Mediterranean diet, the Med Diet 4.0 can contribute to the revitalization of the Mediterranean diet by improving its current perception not only as a healthy diet but also a sustainable lifestyle model, with country-specific and culturally appropriate variations. It also takes into account the identity and diversity of food cultures and systems, expressed within the notion of the Mediterranean diet, across the Mediterranean region and in other parts of the world. Further multidisciplinary studies are needed for the assessment of the sustainability of the Mediterranean diet to include these new dimensions.

On Monday, 28 January 2002, a US Army Chinook helicopter crashed on landing in Afghanistan. Sixteen casualties were airlifted from the scene for treatment at the US Army 274th Forward Surgical Team and the British 34 Field Hospital Troop at Bagram airfield before aeromedical evacuation out of Afghanistan. This was the largest mass casualty incident to be dealt with in a combined fashion by the British and American medical services in Afghanistan during the initial months of Operation ENDURING FREEDOM. It illustrated how multinational surgical teams can successfully manage such incidents by following common and agreed protocols. The lessons learned are relevant to any combined operations in the near future.

The diagnosis and treatment of biliary dyskinesia, defined as symptoms of biliary colic in the absence of gallstones, remains controversial and has been the subject of several previous retrospective reviews. The diagnosis and treatment of biliary dyskinesia based on the CCK-HIDA scan, and the outcome with cholecystectomy for billary dyskinesia, are reviewed. We add more than 200 cases of cholecystectomy for biliary dyskinesia, and compare our results with those of previous reports. We retrospectively reviewed 295 patients with biliary dyskinesia who underwent cholecystectomy at three military hospitals between 1988 and 1995. All patients had symptoms consistent with biliary colic and preoperative evaluations that revealed no evidence of cholelithiasis. Pathology specimens were reviewed for cholelithiasis and pathologic changes. Data were retrieved by chart review and clinic evaluation of new patients. Individual follow-up of each patient was attempted. Follow-up was achieved in 218 of the 295 patients for a rate of 74%. The mean duration of follow-up was 506 days with a range of 22 days to 6 years. Two hundred patients (92%) had CCK-HIDA scans with an ejection fraction (EF) >=<50%. Eighteen patients (8%) had an EF >50% but did have reproduction of their symptoms with CCK injection. In the group with an EF <50%, 94.5% were improved or cured with cholecystectomy. In the group with an EF >50% and pain reproduction, the improved or cured rate was 83.4%. CCK-HIDA scans are useful for diagnosing biliary dyskinesia and predicting improvement after cholecystectomy. Patients presenting with biliary dyskinesia and an EF <50% on CCK-HIDA scan have 94% improvement or resolution of their symptoms after cholecystectorny. CCK-HIDA scans should be employed early in the evaluation of billary colic with no evidence of cholelithiasis (i.e., with a normal ultrasound scan). When test results are abnormal, cholecystectomy should be performed, since the results in this setting approach those of cholecystectomy for stone disease (>90% cured/improved). In the current climate of cost containment, these excellent results would obviate the need for extensive and expensive medical testing before surgical therapy is recommended.
