For males and older females, cross-sectional associations indicated a reduced bone size with higher FM, whereas longitudinal associations showed a decrease in cortical area without changes in bone size. LM was positively associated with BMC and area.
A metabolic health crisis is evident as cardiovascular diseases (CVD) remain the leading cause of mortality in the US. Effects of resistant starch type 4 (RS4), a prebiotic fiber, in comprehensive management of metabolic syndrome (MetS) remain unknown. This study examined the effects of a blinded exchange of resistant starch type-4 (RS4)-enriched flour (30% v/v) with regular/control flour (CF) diet on multiple MetS comorbidities. In a double-blind (participants-investigators), placebo-controlled, cluster crossover intervention (n=86, age ≥18, 2–12week interventions, 2week washout) in the US, individuals were classified as having MetS (With-MetS) or not (No-MetS) following International Diabetes Federation (IDF)-criteria. RS4 consumption compared with CF resulted in 7.2% (p=0.002) lower mean total cholesterol (TC), 5.5% (p=0.04) lower non-HDL, and a 12.8% (p<0.001) lower HDL cholesterol in the With-MetS group. No-MetS individuals had a 2.6% (p=0.02) smaller waist circumference and 1.5% (p=0.03) lower percent body fat following RS4 intervention compared to CF. A small but significant 1% increase in fat-free mass was observed in all participants combined (p=0.02). No significant effect of RS4 was observed for glycemic variables and blood pressures. RS4 consumption improved dyslipidemia and body composition. Incorporation of RS4 in routine diets could offer an effective strategy for public metabolic-CVD health promotion.

SUMMARY We report the case of a 5 month old breast fed infant who presented with a history of vomiting, pallor, and failure to thrive. Investigations showed severe nutritional vitamin B12 deficiency with a megaloblastic pancytopenia. This deficiency was due to low vitamin B12 concentrations in the maternal breast milk, and subsequent investigations showed maternal pernicious anaemia. Treatment of the infant with vitamin B12 resulted in a rapid clinical and haematological improvement. This case represents an unusual presentation of pernicious anaemia.
Sleep deprivation is associated with some, but not all, bone outcomes. These findings may have important public health significance given the increasing prevalence of sleep deprivation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
