This study aimed to document recovery trajectories among adolescents with anorexia nervosa (AN) based on three markers of remission, namely changes in body weight, food restriction, and excessive exercise, and to identify predictors of these trajectories. One hundred twenty-six adolescent girls (14.7 ± 1.

Associations between neurological examination at term-equivalent age and cerebral hemodynamics and oxygen metabolism in infants born preterm.

Background: Infants born at 29-36 weeks gestational age (GA) are at risk of experiencing neurodevelopmental challenges. We hypothesize that cerebral hemodynamics and oxygen metabolism measured by bedside optical brain monitoring are potential biomarkers of brain development and are associated with neurological examination at term-equivalent age (TEA).

Methods: Preterm infants ( = 133) born 29-36 weeks GA and admitted in the neonatal intensive care unit were enrolled in this prospective cohort study.

Neurodevelopmental Outcome of Children with Congenital Heart Disease: A Cohort Study from Infancy to Preschool Age.

Objective: To characterize the neuropsychological outcome of children with congenital heart disease (CHD) at age 5 years; the stability of cognitive and language abilities across childhood; and to identify early neurodevelopmental markers of neuropsychological outcomes in these children.

Study Design: Five-year-old children (n = 55) with complex CHD were assessed using standardized and comprehensive neuropsychological measures. Stability of language and cognitive performance was assessed by comparing standardized scores between ages 1, 2, and 5 years old.

Safety and immunogenicity of a plant-derived rotavirus-like particle vaccine in adults, toddlers and infants.

Background: This study is the first clinical trial for a parenteral non-replicating rotavirus vaccine developed using virus-like particle (VLP) technology.

Methods: This open-labeled, randomized, placebo-controlled trial was conducted in two parts: Part A (a first-in-human study in Australian adults) and Part B (ascending dose and descending age in South African adults, toddlers and infants). In Part A, two cohorts of 10 adults were assigned to receive a single intramuscular injection of 1 of 2 escalating dose levels of the rotavirus VLP (Ro-VLP) vaccine (7 μg or 21 μg) or placebo.

Utility of the Ages and Stages Questionnaires 3rd Edition for Developmental Screening in Children with Surgically Repaired Congenital Heart Disease.

: This study sought to evaluate the accuracy of the Ages and Stages Questionnaires 3rd Edition (ASQ-3) in identifying developmental delay (DD) in children with congenital heart disease (CHD) born at term who underwent surgical repair.: Participants had to complete ASQ-3 and Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) at 12 and 24 months. A child was considered at risk of DD for a ASQ-3 domain when he scored below the cutoff (≤-1SD or ≤-2SD).

Dual regulation of TxNIP by ChREBP and FoxO1 in liver.

TxNIP (Thioredoxin-interacting protein) is considered as a potential drug target for type 2 diabetes. Although TxNIP expression is correlated with hyperglycemia and glucotoxicity in pancreatic β cells, its regulation in liver cells has been less investigated. In the current study, we aim at providing a better understanding of regulation in hepatocytes in response to physiological stimuli and in the context of hyperglycemia in mice.

MG53 is not a critical regulator of insulin signaling pathway in skeletal muscle.

In type 2 diabetes (T2D), both muscle and liver are severely resistant to insulin action. Muscle insulin resistance accounts for more than 80% of the impairment in total body glucose disposal in T2D patients and is often characterized by an impaired insulin signaling. Mitsugumin 53 (MG53), a muscle-specific TRIM family protein initially identified as a key regulator of cell membrane repair machinery has been suggested to be a critical regulator of muscle insulin signaling pathway by acting as ubiquitin E3 ligase targeting both the insulin receptor and insulin receptor substrate 1 (IRS1).

Evaluation of physician burnout at a major trauma centre using the Copenhagen burnout inventory: cross-sectional observational study.

Background: Healthcare workers are susceptible to burnout owing to the demanding nature of their profession. The sequela of this is an increased incidence of medical errors and decreased job satisfaction.

Aims: This study aimed to assess the degree of burnout among physicians of different grades and specialties in a major trauma centre.

Surgical Fires and Burns: A 5-Year Analysis of Medico-legal Cases.

Surgical fires and unintended intraoperative burns cause serious patient harm, yet surveillance data are lacking in Canada. Medico-legal data provide unique descriptions of these events which can inform burn prevention strategies. We extracted 5 years of data on closed (2012-2016) medico-legal cases involving surgical fires and burns from the database of our organization which, in 2016, provided medico-legal support to >93,000 Canadian physicians.

Lipid environment induces ER stress, TXNIP expression and inflammation in immune cells of individuals with type 2 diabetes.

Aims/hypothesis: Obesity and type 2 diabetes are concomitant with low-grade inflammation affecting insulin sensitivity and insulin secretion. Recently, the thioredoxin interacting protein (TXNIP) has been implicated in the activation process of the NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome. In this study, we aim to determine whether the expression of TXNIP is altered in the circulating immune cells of individuals with type 2 vs type 1 diabetes and whether this can be related to specific causes and consequences of inflammation.

Molecular phenotyping of multiple mouse strains under metabolic challenge uncovers a role for in glucose-induced insulin secretion.

Objective: In type 2 diabetes (T2D), pancreatic β cells become progressively dysfunctional, leading to a decline in insulin secretion over time. In this study, we aimed to identify key genes involved in pancreatic beta cell dysfunction by analyzing multiple mouse strains in parallel under metabolic stress.

Methods: Male mice from six commonly used non-diabetic mouse strains were fed a high fat or regular chow diet for three months.

Structure-Activity Relationship of Azaindole-Based Glucokinase Activators.

7-Azaindole has been identified as a novel bidentate anchor point for allosteric glucokinase activators. A systematic investigation around three principal parts of the new small molecule glucokinase activators led to a robust SAR in agreement with structural data that also helped to assess the conformational flexibility of the allosteric activation site. The increase in glucose uptake resulting from glucokinase activation in hepatocytes in vitro translated into the efficient lowering of glucose levels in vivo with the best compounds.

Deletion of apoptosis signal-regulating kinase 1 (ASK1) protects pancreatic beta-cells from stress-induced death but not from glucose homeostasis alterations under pro-inflammatory conditions.

Background: Type 2 diabetes is characterized by pancreatic beta-cell dysfunction and is associated with low-grade inflammation. Recent observations suggest that apoptosis signal-regulating kinase 1 (ASK1) is involved in beta-cell death in response to different stressors. In this study, we tested whether ASK1 deficiency protects beta-cells from glucolipotoxic conditions and cytokines treatment or from glucose homeostasis alteration induced by endotoxemia.

[Choice of career by French medical students after the national ranking exam in 2012].

Purpose: Since 2011, the French medical students ranked after a national ranking exam (NRE) are making their career choice among 11 disciplines detailing the chosen one. Before 2011, this precise choice was unknown. Our work is the first descriptive study of French medical students choice of career after the NRE, precising the medical specialty chosen and the city of practical formation.

[Interaction between environment and genetic background in type 2 diabetes: lessons from animal models].

The respective roles of predisposing genetic factors and environmental factors in the development of type 2 diabetes (T2D) in obese subjects is poorly documented. Rodent models have been set up in an attempt to better understand of the differential effect of a prolonged metabolic stress induced by a high fat diet on glycaemic control according to the genetic background. In utero growth retardation resulting from a hypocaloric diet in pregnant rats induces a dramatic alteration of the development of islet cells leading to diabetes and insulin secretory defects in adult age.

Toxicity of the cyanobacterium Limnothrix AC0243 to male Balb/c mice.

A growing list of freshwater cyanobacteria are known to produce toxic agents, a fact which makes these organisms of concern to water authorities. A cultured strain of Limnothrix (AC0243) was recently shown to have toxic effects in in vitro bioassays. It did not produce any of the known cyanobacterial toxins.

Novel toxic effects associated with a tropical Limnothrix/Geitlerinema-like cyanobacterium.

The presence of a toxic strain of a fine filamentous cyanobacterium belonging to the Oscillatorialean family Pseudanabaenacea was detected during a survey of cyanobacterial taxa associated with the presence of cylindrospermopsin in dams in Central Queensland (Australia). The strain, AC0243, was isolated and cultured, its genomic DNA extracted and 16S RNA gene sequenced. Phylogenetic analysis placed AC0243 with Limnothrix species, although this genus appears polyphyletic.

Variations in plant metallothioneins: the heavy metal hyperaccumulator Thlaspi caerulescens as a study case.

Plant metallothioneins (MTs) are extremely diverse and are thought to be involved in metal homeostasis or detoxification. Thlaspi caerulescens is a model Zn/Cd hyperaccumulator and thus constitutes an ideal system to study the variability of these MTs. Two T.

Evidence for copper homeostasis function of metallothionein (MT3) in the hyperaccumulator Thlaspi caerulescens.

Metallothioneins chelate metals and consequently may be a control point of metal homeostasis. Homologous to type 3 metallothioneins, TcMT3 cDNA was identified in the Cd/Zn hyperaccumulator, Thlaspi caerulescens. TcMT3 amino acid sequence showed modifications in the Cys positions when compared with its Arabidopsis orthologue.

A novel CPx-ATPase from the cadmium hyperaccumulator Thlaspi caerulescens.

Thlaspi caerulescens exhibits a unique capacity for cadmium tolerance and accumulation. We investigated the molecular basis of this exceptional Cd(2+) tolerance by screening for T. caerulescens genes, which alleviate Cd(2+) toxicity upon expression in Saccharomyces cerevisiae.
