RESUMO

The high prevalence of eating disorders in Arab countries indicates a need for an Arabic language screening tool. This study aimed to validate an Arabic version (A-SCOFF) of the British SCOFF questionnaire, a brief tool for the screening of eating disorders in primary health care. After translation and back-translation the A-SCOFF was given to 123 female patients [mean age 32 (SD 8.8) years] visiting primary health-care centres in Beirut. Each patient was evaluated by an eating disorders specialist blinded to A-SCOFF results. The validated Arabic version of the Mini International Neuropsychiatric Interview and the DSM-IV criteria for eating disorders were used as diagnostic references. The best diagnostic threshold for the A-SCOFF was found to be at 2 positive answers with a sensitivity of 80.0%, a specificity of 72.7% and an area under the curve of 80.0%. The A-SCOFF questionnaire is accurate and reliable for the early detection of eating disorders in this high-risk population.

RESUMO

Uncontrolled releases of Tigris and Euphrates River waters after the 2003 war have partially restored some former marsh areas in southern Iraq, but restoration is failing in others because of high soil and water salinities. Nearly 20% of the original 15,000-square-kilometer marsh area was reflooded by March 2004, but the extent of marsh restoration is unknown. High-quality water, nonsaline soils, and the densest native vegetation were found in the only remaining natural marsh, the Al-Hawizeh, located on the Iranian border. Although substantially reduced in area and under current threat of an Iranian dike, it has the potential to be a native repopulation center for the region. Rapid reestablishment, high productivity, and reproduction of native flora and fauna in reflooded former marsh areas indicate a high probability for successful restoration, provided the restored wetlands are hydraulically designed to allow sufficient flow of noncontaminated water and flushing of salts through the ecosystem.

RESUMO

Valproate is often prescribed as a long-term therapeutic mood stabilizing agent for individuals with bipolar disorder. Although research suggests that this drug may produce a neuroprotective effect, its neuroprotective mechanism is not yet clear. The purpose of this study was to determine if valproate provides a neuroprotective effect against damage caused by oxidative stress in primary cultured rat cerebral cortical cells. We found that chronic treatment with valproate at therapeutically relevant concentrations for 7 days inhibited lipid peroxidation and protein oxidation induced by treatment with 0.25 mM oxidant FeCl(3) for 90 min, indicating that valproate inhibits oxidative damage to lipid and protein. Our results suggest that chronic treatment with valproate may protect neuronal cells from damage caused by oxidative stress and that neuroprotection from oxidative damages may be involved in the mechanism of action of valproate. Supporting this possibility are recent findings that chronic treatment with valproate increased the expression of endoplasmic reticulum stress protein GRP78 and antiapoptotic factor bcl-2 in rat cerebral cortex. Since GRP78 binds Ca(2+) and folds damaged protein, bcl-2 stabilizes mitochondrial transmembrane potential and inhibits cytochrome C release, and both GRP78 and bcl-2 have been shown to inhibit oxyradical accumulation, together these findings indicate that valproate may target one or more of these processes in order to produce neuroprotective effects.
