Low Energy Availability, Plasma Lipids, and Hormonal Profiles of Recreational Athletes

This study describes the lipid levels, hormonal profiles, and nutrient intakes of recreationally active adults at risk of LEA compared with those not at risk. Thirty-eight women who meet or exceed the New Zealand guidelines for physical activity participated. Each participant completed an online questionnaire including the Low Energy Availability in Females questionnaire (LEAF-Q), demographic questions, and daily exercise to determine energy expenditure. Participants also provided a weighed 3-day diet record, a blood sample analyzed for total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, and cortisol, and a saliva sample analyzed for testosterone. Body composition was assessed using bioelectrical impedance. Those classed as at risk of LEA according to the LEAF-Q showed very likely lower energy availability (at risk: mean, 36.3 [95% confidence interval, 30.8–41.7] kcal·kg−1·FFMd−1 vs. not at risk: mean, 47.5 [95% CI, 39.5–55.4] kcal·kg−1·FFMd−1) and lower calcium intakes (mean, 847 [95% CI, 695–998] mg, vs. mean, 1488 [95% CI, 690–2,286] mg). Those at risk also had a likely small lower T3 concentration of 1.78 (SD: 0.36) nmol·L−1 compared with 2.01 (SD: 0.53) nmol·L−1 for those not at risk. These data suggest that recreationally active female subjects classed as at risk of LEA according to the LEAF-Q also have lower ener...

RESUMO: Objetivos: Identificar a preval ência da doença renal crônica (DRC) autorreferida no Brasil e caracterizar os fatores associados a essa enfermidade. Métodos: Trata-se de um inquérito epidemiológico de base domiciliar, a Pesquisa Nacional de Saúde (PNS) realizada em 2013. O desfecho analisado foi a prevalência de DRC. Os grupos de variáveis explicativas foram: características sociodemográficas, estilos de vida, doenças crônicas autorreferidas, antropometria e avaliação de saúde. Foram estimadas as prevalê...

CONCLUSION: The matrix effect caused by exogenous and endogenous interferences in the blood could be a hidden factor increasing the prevalence of vitamin D deficiency by causing falsely low 25OHD3 values. Suspicious results should be remeasured by a dilution study. PMID: 32496995 [PubMed - as supplied by publisher]

Abstract All living systems are maintained by a constant flux of metabolic energy and, among the different reactions, the process of lipids storage and lipolysis is of fundamental importance. Current research has focused on the investigation of lipid droplets (LD) as a powerful biomarker for the early detection of metabolic and neurological disorders. Efforts in this field aim at increasing selectivity for LD detection by exploiting existing or newly synthesized probes. However, LD constitute only the final product of a complex series of reactions during which fatty acids are transformed into triglycerides and cho...

In this study, 42 patients with type 2 diabetes were randomly allocated to intervention and control groups and received either 3  g/day dill powder or placebo (3 capsules/day, 1 g each). Fasting blood sugar, insulin, homeostatic model assessment of insulin resistance, lipid profile, high-sensitivity C-reactive protein, total antioxidant capacity, malondialdehyde and gastrointestinal symptoms were measured in all of the su bjects at baseline and postintervention.ResultsThe dill powder supplementation significantly decreased the mean serum levels of insulin, homeostatic model assessment of insulin resistance, l...

ConclusionsOur study demonstrates that our adolescents with severe obesity carry a much higher CV risk than adolescents with T1D unless in bad metabolic control. Apart from lower sAGE levels, most of the variables considered to define CV risk were higher in the obese group than in the T1D group. Gender seems to have a significant impact on sAGE levels but not on IMT.

Niemann-Pick type C (NPC) disease is primarily caused by mutations in the NPC1 gene and is characterized by the accumulation of unesterified cholesterol and lipids in the late endosomal (LE) and lysosomal (Ly) compartments. The most prevalent disease-linked mutation is the I1061T variant of NPC1, which exhibits defective folding and trafficking from the endoplasmic reticulum to the LE/Ly compartments. We now show that the FDA-approved histone deacetylase inhibitor (HDACi) valproic acid (VPA) corrects the folding and trafficking defect associated with I1061T-NPC1 leading to restoration of cholesterol homeostasis, an effect ...
