To assess whether monosodium glutamate (MSG) intake is associated with sleep-disordered breathing (SDB). ⋯ The intake of MSG may increase the risk of SDB in Chinese adults with a normal body weight.

A proposed cutoff point of waist-to-height ratio for metabolic risk in African township adolescents.
A waist:height ratio (WHtR) higher than 0.5 has been proposed as a cutoff point for abdominal obesity in both sexes and at all ages. It is unknown if this cutoff point is appropriate for previously undernourished adolescents. We assessed the cutoff value of the WHtR associated with an increased metabolic risk in 178 black South African 14- to 18-y-old adolescents (69 boys, 109 girls). ⋯ The WHtR cutoff to indicate metabolic risk for black South African adolescents is 0.41, which is lower than the proposed international cutoff of 0.5. The WHtR can be used for screening adolescents with components of the metabolic syndrome in intervention programs.

Proton-pump inhibitors, such as omeprazole, are widely used in the prevention and treatment of gastroesophageal diseases. However, an association between proton-pump inhibitors and the increased risk of bone fractures has been observed, especially in patients treated for extended periods. Conversely, 2-oxoglutarate, a precursor of hydroxyproline, the most abundant amino acid in bone collagen, counteracts the bone loss. The aim of the present study was to elucidate the influence of omeprazole on bone and investigate whether dietary 2-oxoglutarate supplementation could prevent the effects of omeprazole. ⋯ Omeprazole treatment exerts its effects mostly on bone mineralization and cancellous bone, adversely affecting bone properties. This adverse effect of omeprazole was not markedly abolished by 2-oxoglutaric acid, which acted as an anti-hypergastrinemic agent.

Ulcerative colitis is a chronic recurrent disease characterized by acute inflammation of the colonic mucosa. In Japan, a dietary supplementation product enriched with glutamine, dietary fiber, and oligosaccharide (GFO) is widely applied for enteral nutrition support. These three components have been suggested to improve intestinal health. In this study, we investigated whether GFO has suppressive effects on mucosal damage in ulcerative colitis in an experimental mouse model. ⋯ These results suggest that GFO has potential therapeutic value as an adjunct therapy for ulcerative colitis.
