ABSTRACT
Background. South Africa (SA), as a middle-income country, faces the nutrition transition and associated double burden of undernutrition and obesity. School feeding programmes are one way of ensuring that malnutrition in children is addressed, but questions remain about whether they can address both undernutrition and obesity.Objectives. To compare the obesity and stunting outcomes for children receiving different combinations of school feeding programmes in a rural district of SA.Methods. The evaluation involved a comparative design that compared the stunting obesity levels of three groups of children. Group 1 received one lunch meal a day for a prolonged period, group 2 both lunch and breakfast, and group 3 had started receiving a daily lunch shortly before the commencementofthresearch.Results. Group 1 had stunting levels in line with the national average. Group 2 had lower stunting levels than those receiving only the lunch meal. Children from group 3 had lower stunting levels than groups 1 and 2. Rates of obesity and overweight were markedly different between the groups. Group 3 had very high rates of overweight and obesity above the national average of 28%. In contrast, group 1 had far lower rates of overweight and obesity, and group 2exhibited the lowest levels. There was a significant decrease in the percentage of learners classified as overweight in group 3 over the 6-month period, from 26.1% to 19.2%.Conclusion. One lunch meal a day is associated with positive outcomes in relation to rates of stunting and obesity, and the lowest rates of obesity were measured when a breakfast meal was added. The addition of a breakfast meal to a lunch feeding programme shows promise,but this requires further investigation to understand whether causal linkages exist

Seasonal affective disorder is a combination of biologic and mood disturbances with a seasonal pattern, typically occurring in the autumn and winter with remission in the spring or summer. In a given year, about 5 percent of the U.S. population experiences seasonal affective disorder, with symptoms present for about 40 percent of the year. Although the condition is seasonally limited, patients may have significant impairment from the associated depressive symptoms. Treatment can improve these symptoms and also may be used as prophylaxis before the subsequent autumn and winter seasons. Light therapy is generally well tolerated, with most patients experiencing clinical improvement within one to two weeks after the start of treatment. To avoid relapse, light therapy should continue through the end of the winter season until spontaneous remission of symptoms in the spring or summer. Pharmacotherapy with antidepressants and cognitive behavior therapy are also appropriate treatment options and have been shown to be as effective as light therapy. Because of the comparable effectiveness of treatment options, first-line management should be guided by patient preference.
ABSTRACT
Osteoporosis is a common disease that is associated with increased risk of fractures and serious clinical consequences. Bone mineral density (BMD) testing is used to diagnose osteoporosis, estimate the risk of fracture, and monitor changes in BMD over time. Combining clinical risk factors for fracture with BMD is a better predictor of fracture risk than BMD or clinical risk factors alone. Methodologies are being developed to use BMD and validated risk factors to estimate the 10-year probability of fracture, and then combine fracture probability with country-specific economic assumptions to determine cost-effective intervention thresholds. The decision to treat is based on factors that also include availability of therapy, patient preferences, and co-morbidities. All patients benefit from nonpharmacological lifestyle treatments such a weight-bearing exercise, adequate intake of calcium and vitamin D, fall prevention, avoidance of cigarette smoking and bone-toxic drugs, and moderation of alcohol intake. Patients at high risk for fracture should be considered for pharmacological therapy, which can reduce fracture risk by about 50 percent.
Osteoporose é uma doença comum, que está associada a um aumento do risco de fraturas e de importantes conseqüências clínicas. A densidade mineral óssea (DMO) é o método usado para o diagnóstico da osteoporose, estimando o risco de fratura e monitorando as alterações da DMO durante o tempo. A combinação de fatores de risco para fraturas com a densidade mineral óssea é melhor preditor do risco de fratura do que um deles isoladamente. Metodologias estão sendo desenvolvidas para usar a DMO e fatores de risco validados para estimar o risco de fraturas em 10 anos. A decisão de tratar também está baseada em fatores que incluem terapia disponível, preferência do paciente e co-morbidades. Todos os pacientes se beneficiam de medidas não farmacológicas tais como uma ingesta adequada de cálcio e vitamina D, prevenção de queda, evitar tabagismo e drogas de efeito tóxico ao osso. Pacientes de alto risco de fraturas devem ser considerados para o tratamento farmacológico, os quais podem reduzir este risco em 50 por cento.
