The development of formal transition models emerged to reduce variability in care, including cystic fibrosis (CF) responsibility, independence, self-care, and education (RISE), which provides a standardized transition program, including knowledge assessments, self-management checklists, and milestones for people with CF. Despite these interventions, the current landscape of health care transition (HCT) remains suboptimal, and additional focused attention on HCT is necessary. Standardization of assessment tools to gauge the efficacy of transfer from pediatric to adult care is a high priority.

We hypothesized that 12-week HIIT increases insulin sensitivity in males with or without type 2 diabetes [T2D and NDM (nondiabetic humans)]. However, despite identically higher VOmax, mainly insulin-resistant (IR) persons (T2D and IR NDM) showed distinct alterations of circulating small extracellular vesicles (SEVs) along with lower inhibitory metabolic (protein kinase Cε activity) or inflammatory (nuclear factor κB) signaling in muscle of T2D or IR NDM, respectively.

This study aimed to develop reference values of HGS in Italian women with different categories of body mass index (BMI). Additionally, the main predictors of HGS were identified.

Our study aims to evaluate if some indicators of disease severity, as body mass index (BMI), Phase Angle (PhA) and months of amenorrhea may be predictors of metabolic alterations (serum albumin, liver enzymes).
Methods: In 154 outpatients with AN, case history was collected, and anthropometric and laboratory parameters measured.
Background: This study aimed to evaluate several socio-demographic and long-term clinical outcomes in a cohort of women living with a restrictive eating disorder.
Methods: Patients were asked to fill in a general data collection form aiming to investigate their current conditions and to attend the outpatient unit for a 10-year follow-up clinical and laboratory evaluation.
Results: Forty-four patients completed the follow-up general data collection form and 20 agreed to attend the outpatient unit for the 10 year-follow-up evaluation.
A and A adenosine receptors (ARs) are closely related G protein-coupled receptor subtypes, which represent important (potential) drug targets. Despite their almost identical binding sites for adenosine, AARs are activated by low (nanomolar) adenosine concentrations, while AARs require micromolar concentrations. In the present study, we exchanged the extracellular loop 2 (ECL2) of the human AAR for that of the AAR.

In this study, we prepared the fully efficacious, nonbiased GPR84 agonist 6-hexylamino-2,4(1,3)-pyrimidinedione () in tritium-labeled form ([H]PSB-1584) by hydrogenation of a hexenyl-substituted precursor with tritium gas. The radioligand was characterized by kinetic, saturation, and competition assays using membranes of Chinese hamster ovary cells recombinantly expressing the human GPR84.

We monitored skeletal muscle metabolism in obese individuals before and over 52 weeks after metabolic surgery. Initial weight loss occurs in parallel with a decrease in muscle oxidative capacity and respiratory control ratio.

This cross sectional study aims to evaluate resting energy expenditure (REE) and phase angle as a marker of qualitative changes of fat free mass (FFM) in three leanness groups as compared with control subjects.
Methods: 17 anorectic (AN) males, 15 constitutionally lean (CL) individuals, 12 ballet dancers (DC), and 18 control (CTR) subjects were evaluated.
Nutritional disorders such as Anorexia Nervosa (AN) can shape the composition of gut microbiota and its metabolites such as short chain fatty acid (SCFA). This study aims to compare fecal SCFA along with dietary intake of women with restrictive AN (r-AN = 10) and those of sex-matched lean controls (C = 8). The main fecal short chain fatty acids (SCFA) were assessed by gas chromatography equipped with a flame ionization detector.

Adipose tissue is an endocrine organ, secreting various adipokines, either directly or via extracellular vesicles, including exosomes. Exosomes are vesicles of 40-150 nm size that represent a novel concept of biomolecule release. We purified exosomes from isolated primary human preadipocytes differentiated to mature adipocytes.

This study examined the relationship of sphingolipids with hepatic and peripheral metabolism in 21 insulin-resistant obese patients without (NAFL-) or with (NAFL+) nonalcoholic fatty liver and nonalcoholic steatohepatitis (NASH) and 7 healthy lean individuals undergoing tissue biopsies during bariatric or elective abdominal surgery.
Research Design And Methods: Hyperinsulinemic-euglycemic clamps with d-[6,6-H]glucose were performed to quantify tissue-specific insulin sensitivity.
The adenosine receptor (AR) subtypes A and A are rhodopsin-like G protein-coupled receptors whose expression is highly regulated under pathological, e.g. hypoxic, ischemic and inflammatory conditions.

The aim of this retrospective study was to assess the accuracy of selected BIA (bioimpedance analysis) equations for fat-free mass (FFM) in female AN subjects and to formulate a specific equation for these subjects.
Methods: Eighty-two restrictive female AN subjects (age 20.
Purpose: GPR143 regulates melanosome biogenesis and organelle size in pigment cells. The mechanisms underlying receptor function remain unclear. G protein-coupled receptors (GPCRs) are excellent pharmacologic targets; thus, we developed and applied a screening approach to identify potential GPR143 ligands and chemical modulators.

Methods: Thirteen r-AN patients and 13 healthy female controls completed 7-d food records. Intake of macro- and micronutrients was compared between the two groups as well as to the Dietary Reference Intake for the Italian Population (LARN) for specific ages.
Background/objectives: Anemia, leukopenia and, although less frequently, thrombocytopenia are possible hematological complications of anorexia nervosa considered strictly secondary to chronic malnutrition. This is a retrospective study on the prevalence of these disorders in a large cohort of 318 female patients with AN (20.4±5.

Mutations result in dysfunctional melanosome biogenesis and macromelanosome formation in pigment cells, including melanocytes and retinal pigment epithelium. GPR143, primarily expressed in pigment cells, localizes exclusively to endolysosomal and melanosomal membranes unlike most G protein-coupled receptors, which localize to the plasma membrane.

It seems to play a role in whole body metabolism, but it has not been evaluated in underweight conditions, such as in young females with constitutional leanness (CL) or anorexia nervosa (AN).
