The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional to ITS rDNA as primary barcode. Amplification efficiencies of 14 (partially) universal primer pairs targeting eight genetic markers were tested across > 1 500 species (1 931 strains or specimens) and the outcomes of almost twenty thousand (19 577) polymerase chain reactions were evaluated. We tested several well-known primer pairs that amplify: i) sections of the nuclear ribosomal RNA gene large subunit (D1-D2 domains of 26/28S); ii) the complete internal transcribed spacer region (ITS1/2); iii) partial -tubulin II (TUB2); iv) -actin (ACT); v) translation elongation factor 1- (TEF1); and vi) the second largest subunit of RNA-polymerase II (partial RPB2, section 5-6). Their PCR efficiencies were compared with novel candidate primers corresponding to: i) the fungal-specific translation elongation factor 3 (TEF3); ii) a small ribosomal protein necessary for t-RNA docking; iii) the 60S L10 (L1) RP; iv) DNA topoisomerase I (TOPI); v) phosphoglycerate kinase (PGK); vi) hypothetical protein LNS2; and vii) alternative sections of TEF1. Results showed that several gene sections are accessible to universal primers (or primers universal for phyla) yielding a single PCR-product. Barcode gap and multi-dimensional scaling analyses revealed that some of the tested candidate markers have universal properties providing adequate infra- and inter-specific variation that make them attractive barcodes for species identification. Among these gene sections, a novel high fidelity primer pair for TEF1, already widely used as a phylogenetic marker in mycology, has potential as a supplementary DNA barcode with superior resolution to ITS. Both TOPI and PGK show promise for the Ascomycota, while TOPI and LNS2 are attractive for the Pucciniomycotina, for which universal primers for ribosomal subunits often fail.

Pediatric obesity has increased dramatically all over the world and nonalcoholic fatty liver disease (NAFLD) is one of the most frequent complications associated with excess adiposity. NAFLD causes serum transaminase elevation and liver disease, which could end up in fibrosis, cirrhosis and eventually hepatocellular carcinoma. NAFLD seems to be associated with the metabolic complications of obesity, mainly insulin resistance. The aim of the present article is to review the role of serum liver enzyme assessment as asuitable non invasive predictor of NAFLD in children. Although serum liver enzyme elevation does not accurately measure liver damage, it may be a valuable and non invasive test to screen NAFLD in children and adolescents and a marker to control NAFLD evolution. To detect NAFLD in obese children and adolescents, transaminases serum concentrations should be routinely determined in these patients. In this sense, it seems necessary to obtain transaminase reference standards for children and adolescents.

Introduction: Physical and psychological complications in obese individuals are important and lead to health spending (about 7% in 2011). Two thirds of adult population in Europe have not sufficient physical activity to maintain a satisfactory health state. To induce behavioral change, play on the adapted physical activity program would strengthen feeling of competence, considered as a powerful vector to change these behaviors. Objectives: The main objective is to enhance the sense of competence in the field of adapted physical activity, and long-term goal is to generate commitment in regular practice. Methods: The management is done in Roubaix Hospital (10 weeks, with two sessions per week, one supervised in STEP 1h30 and the other independently walking). Five patients have participated in this study where we measured psychological variables with SEPOB (the emotional, cognitive and behavioural questionnaire of self-efficacy in weight management) and physical variables using a stress test. © 2015, Springer-Verlag France.

Background: Total esophagogastric dissociation (TED) was first described in 1997 by Bianchi as a new surgical procedure to treat severe gastroesophageal reflux disease (GERD) in children with neurological impairment. Recently, TED has been proposed in other conditions, such as esophageal atresia, esotracheal cleft, or caustic esophageal lesions. Although the long-term results in terms of GERD control have been previously reported, those regarding the nutritional and metabolic status have never been documented. Patients and Methods: All patients without neurological impairment with TED between 1999 and 2004 at Robert Debre Hospital and Jeanne de Flandre Hospital, France, were prospectively investigated, paying particular attention to their metabolic and nutritional status (blood concentration of iron and vitamins A, D, E, and B12; lipid malabsorption; and hyperglycemia test) and growth. Results: Seventeen children underwent TED. Six received primary procedures, whereas 11 were operated on because of severe respiratory diseases or failure to thrive. The mean follow-up was 6 years (range 3-8 years). Two children died (12%). Seven children were weaned from enteral nutrition support, but 5 of them had failure to thrive, steatorrhea, and/or malabsorption of vitamin B12 and/or fat-soluble vitamins. Eight patients had dumping syndrome, which was symptomatic in 6 cases. Conclusions: TED is an effective procedure for treatment of GERD. However, nutritional and metabolic complications including dumping syndrome and chronic digestive malabsorption are frequent after TED, especially after enteral nutrition weaning. A long-term follow-up of these patients is thus necessary and prolonged enteral nutrition support is recommended. Copyright © 2010 by Lippincott Williams & Wilkins.

Recent development of high-throughput sequencing methods has shown that the human respiratory tract (including lower airways) is not sterile as formerly thought, but composed of a previously unappreciated complex microbial community referred as the lung microbiome and composed of bacteria, viruses and fungi. However, many questions remain unresolved, especially in terms of lung microbiome role, its interactions with host but also with environmental pathogens. Although data are still limited, links have already been demonstrated between lung microbiome and chronic respiratory diseases (such as asthma, chronic obstructive pulmonary disease or cystic fibrosis). This lung microbiome appears to play an important role both in disease genesis and evolution, and consequently offers an emerging research field. © 2015 médecine/sciences - Inserm.

Sjögren's syndrome is a chronic inflammatory disorder characterized by lymphocytic infiltration of exocrine glands, mainly the lacrimal and salivary glands. However, extraglandular organ systems may frequently be involved, including the lungs. Although subclinical pulmonary inflammation exists in more than 50% of patients, clinically significant pulmonary involvement affects approximately 10% of patients and may be the first manifestation of the disease. The entire respiratory tract may be involved, with a wide spectrum of manifestations including xerotrachea and bronchial sicca, obstructive small airway disease, various patterns of interstitial lung disease, lymphoinfiltrative or lymphoproliferative lung disease, such as lymphoma (usually of MALT type), pulmonary hypertension, pleural involvement, lung cysts, and pulmonary amyloidosis.

Objective: Several studies report calcium mishandling, sarcomere disarray, and caspase activation during heart failure. Although active caspases have been shown to cleave myofibrillar proteins, little is known regarding their effects on calcium handling proteins. Therefore, we aimed to explore how endotoxin-induced caspase activation disrupts intracellular calcium regulation. Design: Randomized controlled trial. Setting: Small animal research laboratory. Subjects: Adult male Sprague-Dawley rats. Interventions: Sepsis was induced by injection of endotoxin (10 mg/kg, intravenously). Caspase inhibition was achieved by coinjection with zVAD.fmk (3 mg/kg, intravenously). We first isolated adult rat ventricular myocytes from control, endotoxin, and (endotoxin + zVAD)-treated rats to characterize contractile parameters and cellular calcium homeostasis. Underlying molecular mechanisms responsible for calcium mishandling were explored on sarcoplasmic reticulum vesicles and mitochondria prepared from treated animals. All experiments were performed 4 hrs postendotoxin treatment. Measurements and main results: zVAD normalized reductions in fractional cell shortening and relaxation rate triggered by endotoxin treatment. Both sarco-/endoplasmic reticulum Ca-ATPase and mitochondria-dependent calcium uptakes were impaired after endotoxin treatment and prevented when myocytes were isolated from zVAD-treated endotoxinic rat hearts. zVAD blocked endotoxin-induced phospholamban dephosphorylation, protein phosphatase 2A activation, and mitochondrial calcium retention capacity reduction. To strengthen these results, control sarcoplasmic reticulum vesicles and mitochondria were incubated with active recombinant caspase-3. Although no effects were observed on mitochondria, caspase-3 directly exerts detrimental effects on sarcoplasmic reticulum calcium uptake capacity by activating protein phosphatase 2A, leading to phospholamban dephosphorylation. Conclusions: Caspase inhibition protects from endotoxin-induced sarcoplasmic reticulum calcium uptake capacity reduction and mitochondrial dysfunction. © 2010 by the Society of Critical Care Medicine and Lippincott Williams & Wilkins.

Transgastric jejunal intubation via gastrostomy (GJ) can be indicated when enteral nutrition via gastrostomy is not possible. Between 2001 and 2008, the authors prospectively assessed the outcomes in 29 patients (median age, 10 months) after GJ. Indications for jejunal feeding were severe gastro-oesophageal refl ux (n=27) and intestinal dysmotility (n=2). The GJ was successfully placed in 27/29 patients. Complications were: 31 tube dislodgements, 16 obstructions, 7 leakages around the tube, 6 internal balloon ruptures and 1 intussusception. The median lifetime of the tube was 3 months. 9/27 patients died during the study period, 11 patients required surgery, 2 required parenteral nutrition, gastric feeding became tolerated in 3 and the gastrojejunal feeding tube was kept in place in the remaining 2. A transgastric jejunal feeding tube may constitute a transitory alternative to antirefl ux surgery or prolonged parenteral nutrition. However, the high frequency of complications and tube replacement limits its use.

Background: To compare the results of the endovascular aneurysm repair (EVAR) in patients considered as unfit for surgery in a "high volume" center with the EVAR-2 trial results. Methods: In our center, between January 2006 and December 2008, 469 endovascular aorta treatments were performed in high-risk patients. All the data were prospectively collected in a database. Among 469 patients, we selected 191 patients considered as unfit for open surgery (group 1) corresponding to the EVAR trial criteria. Variables such as postoperative mortality at 30 days and 1 year, complications rates, as well as early and late redo surgery were evaluated. Long-term pharmacological treatment before surgery was listed. These results were compared with the EVAR trial (group 2). Survival during the follow-up was calculated according to the Kaplan-Meier method. Results: Mortality at 30 days was 1.6% and 9% in groups 1 and 2, respectively (p = 0.002). Global complication rate was 44% and 43% in groups 1 and 2, respectively (p = 0.52). Over the follow-up period, the redo surgery rate was 13% and 26% in groups 1 and 2, respectively (p = 0.0102). In our cohort, the survival rate at 2 years was 84% with a residual number of 102 patients. Before surgery, a long-term antiplatelet treatment was prescribed in 89% and 58% of the patients and statins in 74% and 39% of the patients in groups 1 and 2, respectively (p < 0.0001). Conclusion: The EVAR-2 trial conclusions are in opposition to the practice of French vascular surgeons. Endovascular treatment of abdominal aortic aneurysms in high-risk patients is justified. This study confirms the importance of a multidisciplinary treatment for high-risk patients in high-volume centers. © Annals of Vascular Surgery Inc.

Located at the feto-maternal interface, the placenta is involved in exchange, endocrine and immune functions, which impact fetal development. In contact with the maternal environment, this organ is sensitive to metabolic disorders as over-nutrition, obesity or diabetes. The alteration of blood parameters associated with these pathologies affects placental histology, vascularization and nutrient transfers and, according to the types of troubles, induces local inflammation or hypoxia. These placental changes lead to disturbance of development and fetal growth, which increase the risk of pathologies in offspring in adulthood. The placenta thus appears as a crucial player in the fetal programming.
