The aim of this study was to investigate the association between the magnitude of weight loss (WL) and serum concentrations of the main adipocytokines and appetite-regulating hormones in adolescents with obesity. ⋯ Weight loss >10% seems to reverse obesity-induced hyperleptinemia while stabilizing the neuropeptides that control appetite in adolescents with obesity. We were able to produce a prognostic mathematical model to predict body fat loss using weight, leptin, and α-MSH variations.

Information is limited regarding the possible relationship between diet-related inflammation and the risk of gestational diabetes mellitus (GDM). This study investigated the association between the inflammatory potential of the diet, measured by the dietary inflammatory index (DII), and GDM risk in pregnant Chinese women. ⋯ These findings suggest that a higher DII score, corresponding to a more proinflammatory diet, is associated with a higher risk of GDM, particularly in pregnant women who were overweight or obese before pregnancy.

Case report The importance of vitamin D in treatment of fracture non-union: A case report.
The prevalence of hypovitaminosis D is currently increasing. A wide variety of diseases and complications are associated with low vitamin D serum concentrations, including poor fracture healing and fracture non-union. A healthy 44-y-old man presented himself with pain due to a non-union of a femoral shaft fracture at 4 y after the initial injury. ⋯ Hypovitaminosis D was diagnosed, and subsequent supplementation resulted in complete union of the fracture with full pain relief. This case illustrates the importance of adequate serum vitamin D levels in fracture healing, in addition to other fracture healing facilitating factors. With the increasing prevalence of hypovitaminosis D and possibly associated fracture-related complications, routine vitamin D determination should become part of clinical workup in cases of fracture non-union.

Childhood obesity is a critical health issue. The etiology of childhood obesity is multifactorial, with age, gender, race/ethnicity, and socioeconomic status interacting to affect risk. Food insecurity is known to be associated with risk of childhood obesity, but the body of evidence regarding Koreans is lacking. This study investigated the association between childhood obesity and household food insecurity in Koreans. Other lifestyle and nutritional factors associated with obesity were also examined. ⋯ Differential lifestyle factors are associated with obesity phenotypes in boys and girls. Food insecurity also showed a contrasting association with obesity risk by gender in young Koreans.

Acetate, propionate, and butyrate, three of the most common short-chain fatty acids (SCFAs), can be produced when some non-digestible carbohydrates enter the large intestine and undergo bacterial fermentation. The aim of this study was to investigate the effects of these three SCFAs on appetite regulation and lipid metabolism and to determine the extent that appetite contributes to the beneficial influences of SCFAs. ⋯ Taken together, SCFAs could reduce appetite and fat accumulation via modulating relevant genes and hormones, which might further illustrate the potential mechanisms that underlay the effects of SCFAs on lipid homeostasis and control of body weight.
