Background: Angiopoietin growth factors (Angs) regulate angiogenesis and lymphangiogenesis by binding to the endothelial Tie2 receptor. Ang2 expression is elevated in tissue hypoxia and inflammation, which also induce cleavage of the extracellular domain of the orphan Tie1 receptor. Here we have examined if the concentrations of Ang2 and the soluble extracellular domain of Tie1 in patient plasma are associated with the prognosis of patients with metastatic breast cancer., Methods: Plasma Tie1 and Ang2 levels were measured in metastatic breast cancer patients treated in a phase II trial with a taxane-bevacizumab combination chemotherapy in the first-line treatment setting. They were analyzed before treatment, after 6 weeks and 6 months of treatment, and at the final study visit. Using the median concentrations as cutoffs, Tie1 and Ang2 data were dichotomized into low and high concentration groups. Additionally, we analyzed Tie1 concentrations in plasma from 10 healthy women participating in a breast cancer primary prevention study., Results: Plasma samples were available from 58 (89%) of the 65 patients treated in the trial. The baseline Tie1 levels of the healthy controls were significantly lower than those of the metastatic patients (p < 0.001). The overall survival of the patients with a high baseline Tie1 level was significantly shorter (multivariate HR 3.07, 95% CI 1.39-6.79, p = 0.005). Additionally, the progression-free survival was shorter for patients with a high baseline Tie1 level (multivariate HR 3.78, 95% CI 1.57-9.09, p = 0.003). In contrast, the baseline Ang2 levels had no prognostic impact in a multivariate Cox proportional hazard regression analysis. The combined analysis of baseline Tie1 and Ang2 levels revealed that patients with both high Tie1 and high Ang2 baseline levels had a significantly shorter overall survival than the patients with low baseline levels of both markers (multivariate HR for overall survival 4.32, 95% CI 1.44-12.94, p = 0.009)., Conclusions: This is the first study to demonstrate the prognostic value of baseline Tie1 plasma concentration in patients with metastatic breast cancer. Combined with the results of the Ang2 analyses, the patients with both high Tie1 and Ang2 levels before treatment had the poorest survival., Trial Registration: Clinicaltrials.gov: NCT00979641, registration date 19-DEC-2008.

Cystic fibrosis (CF) patients are commonly colonized by bacterial pathogens, which can induce persistent lung inflammation and may contribute to clinical deterioration. Colonization of CF patients and cross-transmission by Corynebacterium diphtheriae have not been reported so far. The aim of this article was to investigate the possibility of a cross-transmission of C. diphtheriae biovar Belfanti between four patients of a CF center. C. diphtheriae biovar Belfanti (now formally called C. belfantii ) isolates were collected from four patients in a single CF care center over a period of 6 years and analyzed by microbiological methods and whole-genome sequencing. Epidemiological links among patients were investigated. Ten isolates were collected from 4 patients. Whole-genome sequencing of one isolate from each patient showed that a single strain was shared among them. In addition, one patient was found to have the same strain in two consecutive samplings performed 9 months apart. The strain was nontoxigenic and was susceptible to most antimicrobial agents. Ciprofloxacin resistance was observed in one patient. The idea of transmission of the strain among patients was supported by the occurrence of same-day visits to the CF center. This study demonstrated colonization of CF patients by C. diphtheriae biovar Belfanti ( C. belfantii ), and the data suggest persistence and transmission of a unique strain during at least 6 years in a single CF patient care center., (Copyright © 2019 American Society for Microbiology.)

Background: Immunomodulatory drugs (thalidomide, lenalidomide and pomalidomide; IMID) are widely used in the treatment of multiple myeloma patients. To date, few data are available on IMID adherence in multiple myeloma patients. The aim of our study was to evaluate IMID adherence and to compare two indirect methods to measure IMID adherence in multiple myeloma patients: a specific questionnaire and the medication possession ratio (MPR). Another aim was to explore this specific questionnaire for the assessment of IMID adherence in multiple myeloma patients., Methods: All consecutive multiple myeloma patients, with at least two consecutive dispensations of thalidomide, lenalidomide or pomalidomide in our hospital were included in this prospective study. IMID adherence was measured using a specific questionnaire and the medication possession ratio. Relationship between the questionnaire scores and variables of interest was evaluated by multiple linear regression with a robust variance estimator., Findings: Sixty-three patients were included in our study. The mean questionnaire score was 8.2±1.2 and the mean medication possession ratio value was 0.97±0.06. A total of 76% of patients were considered adherent according to the questionnaire (i.e. score ≥ 8), 94% according to the medication possession ratio (i.e. MPR ≥ 0.90), and 70% according to the questionnaire and the medication possession ratio. No statistically significant linear association was observed between the questionnaire score and any variables of interest including medication possession ratio. All Cronbach's alpha were relatively low (range 0.0342-0.2443), showing a low correlation of the different questions with the questionnaire score., Conclusions: Our study is the first prospective study evaluating IMID adherence in multiple myeloma patients in real life. The high adherence to IMIDs reported here, regardless of the drug, is encouraging considering the efficacy, toxicity and elevated cost of IMIDs. The specific questionnaire should be used with caution to evaluate IMID adherence., Competing Interests: The authors have declared that no competing interests exist.

Introduction: The use of extracorporeal life support (ECLS) is increasing worldwide, in particular for the management of refractory cardiac arrest, cardiogenic shock and post cardiopulmonary bypass ventricular failure. Extubation of patients under extracorporeal membrane oxygenation (ECMO) for respiratory failure is a growing practice for adult and pediatric patients, especially for lung transplantation candidates. Because of potential complications and, specifically, accidental arterial decannulation, extubation of patients under ECLS is not standard practice. Our goal was to evaluate the interest in patient extubation under ECLS., Materials and Methods: We performed a monocentric, retrospective study of all ECLS cases between January 2014 and January 2016. We excluded patients who died within the first 48 hours of ECLS., Results: We analyzed 57 of the initial 109 patients included in the study. The initial SOFA score was higher in the non-extubated group under ECLS, without significant difference (8.6 ± 2.8 vs 7.2 ± 2.1, p=0.065). Patients who were not extubated had a higher rate of acquired ventilator pneumonia (61.9% vs 26.7%, p=0.03). Moreover, patients who were extubated under ECLS had better 30-day survival rates (73.3% vs 40.5%, p=0.04). In multivariate analyses, the independent factors associated with mortality were age, duration of ECLS and the lack of extubation under ECLS., Conclusion: Extubation of patients under ECLS is safe and feasible. Furthermore, in extubated patients, we observed fewer cases of ventilator-associated pneumonia and better 30-day survival rates.

Background: HIV infection is a chronic disease for which therapeutic adherence and tolerance require particular attention., Objective: This study aimed to assess whether and when therapeutic drug monitoring (TDM) could be associated with a benefit in routine practice., Methods: All HIV-infected patients who underwent at least one TDM at the University Hospital of Dijon (France) between 1st January 2009 and 31st December 2012 were retrospectively included. Compliance with the recommendations, the results (antiretroviral concentrations), any subsequent therapeutic modifications, and the virological results at 4-8 months were analysed each time TDM was performed. TDM was defined as "practically relevant" when low or high antiretroviral concentrations led to a change in therapy., Results: Of the 571 patients who followed-up, 43.4% underwent TDM. TDM complying with recommendations (120 patients) was associated with a higher proportion of antiretroviral concentrations outside the therapeutic range (p=0.03). Antiretroviral treatment was modified after TDM in 22.6% of patients. Protease inhibitors, non-nucleoside reverse transcriptase inhibitors and raltegravir were more significantly modified when the measured concentration was outside the therapeutic range (p=0.008, p=0.05 and p=0.02, respectively). Overall, 11.7% of TDM was considered "practically relevant", though there was no significant correlation between subsequent changes in antiretroviral treatment and undetectable final HIV viral load., Conclusion: TDM may be a useful tool in the management of HIV infection in specific situations, but the overall benefit seems moderate in routine practice. TDM cannot be systematic and/or a decision tool per se, but should be included in a comprehensive approach in certain clinical situations., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Context: Epidemiology is a discipline which has evolved with the changes taking place in society and the emergence of new diseases and new discipline related to epidemiology. With these evolutions, it is important to understand epidemiology and to analyse the evolution of content of definitions of epidemiology., Objectives: The main objective of this paper was to identify new definitions of epidemiology available since 1978. Secondary objectives were to analyse the content of these definitions, to compare them with those used by Lilienfeld and to determine whether changes have taken place over the last forty years., Methods: A review of grey literature and published literature was conducted to find the definitions of epidemiology written between 1978 and 2017., Results: 102 definitions of epidemiology were retained. They helped to highlight 20 terms and concepts related to epidemiology. Most of them were already used in the definitions used by Lilienfeld. Five terms were present in more than 50% of definitions from the period 1978 to 2017: "population", "study", "disease", "health" and "distribution". Several developments have occurred: strengthening of the terms "control" and "health" already used, the concept of "disease" was less frequently encountered whereas the concepts "infectious diseases", "mass phenomenon" are no longer used in definitions from 1978 to 2017., Conclusion: This evolution of content of definition of epidemiology is absent from books on epidemiology. A thematic analysis of definitions of epidemiology could be conducted in order to improve our understanding of changes observed., Competing Interests: The authors have declared that no competing interests exist.

Purpose: To identify predictive factors of tumor response, progression-free survival (PFS), overall survival (OS), and toxicity using three-dimensional (3D) voxel-based dosimetry in patients with intermediate and advanced stage hepatocellular carcinoma (HCC) treated by yttrium-90 ( 90 Y) resin microspheres radioembolization (RE)., Materials and Methods: From February 2012 to December 2015, 45 90 Y resin microspheres RE procedures were performed for HCC (Barcelona Clinic Liver Cancer stage B/C; n = 15/30). Area under the dose-volume histograms (AUDVHs) were calculated from 3D voxel-based dosimetry to measure 90 Y dose deposition. Factors associated with tumor control (ie, complete/partial response or stable disease on Modified Response Evaluation Criteria in Solid Tumors) at 6 months were investigated. PFS and OS analyses were performed (Kaplan-Meier). Toxicity was assessed by occurrence of radioembolization-induced liver disease (REILD)., Results: Tumor control rate was 40.5% (17/42). Complete tumor targeting (odds ratio = 36.97; 95% confidence interval, 1.83-747; P < .001) and AUDVH tumor (odds ratio = 1.027; 95% confidence interval, 1.002-1.071; P = .033) independently predicted tumor control. AUDVH tumor ≥ 61 Gy predicted tumor control with 76.5% sensitivity and 75% specificity. PFS and OS in patients with incomplete tumor targeting were significantly shorter than in patients with complete tumor targeting (median PFS, 2.7 months [range, 0.8-4.6 months] vs 7.9 months [range, 2.1-39.5 months], P < .001; median OS, 4.5 months [range, 1.4-23 months] vs 19.2 months [range, 2.1-46.9 months], P < .001). Patients with incomplete tumor targeting and AUDVH tumor < 61 Gy, incomplete tumor targeting and AUDVH tumor > 61 Gy, complete tumor targeting and AUDVH tumor < 61 Gy, and AUDVH tumor > 61 Gy had median PFS of 2.7, 1.8, 6.3, and 12.1 months (P < .001). REILD (n = 4; 9.5%) was associated with higher dose delivered to normal liver (P = .04)., Conclusions: Complete tumor targeting and 90 Y dose to tumor are independent factors associated with tumor control and clinical outcomes., (Copyright © 2018 SIR.

Objective: The aim of this study was to investigate the impact of a rotating sound stimulation on the postural performances in normal subjects, patients with bilateral vestibulopathy (BVP), unilateral (UCI), and bilateral (BCI) cochlear implantees. Materials and Methods: Sixty-nine adults were included (32 women and 37 men) in a multicenter prospective study. The group included 37 healthy subjects, 10 BVP, 15 UCI, and 7 BCI patients. The average of age was 47 ± 2.0 (range: 23-82). In addition to a complete audiovestibular work up, a dynamic posturography (Multitest Framiral, Grasse) was conducted in silence and with a rotating cocktail party sound delivered by headphone. The center of pressure excursion surface (COPS), sensory preferences, as well as fractal, diffusion, and wavelet analysis of stabilometry were collected. Results: The rotating sound seemed to influenced balance in all subgroups except in controls. COPS increased with sound in the BVP and BCI groups in closed eyes and sway-referenced condition indicating a destabilizing effect while it decreased in UCI in the same condition suggesting stabilization ( p < 0.05, linear mixed model corrected for age, n = 69). BVP had higher proprioceptive preferences, BCI had higher vestibular and visual preferences, and UCI had only higher vestibular preferences than controls. Sensory preferences were not altered by rotating sound. Conclusions: The rotating sound destabilized BVP and BCI patients with binaural hearing while it stabilized UCI patients with monaural hearing and no sound rotation effect. This difference suggests that binaural auditory cues are exploited in BCI patients for their balance.

Background: Minimal invasive heart surgery (MIHS) presents several benefits, but provides intense and prolonged post-operative pain. Our objective was to compare efficacy of serratus anterior plane block (SAPB) with continuous wound infiltration (CWI) for management of post-operative pain following MIHS., Methods: It's retrospective, monocentric study between November 2016 to April 2017. The study was performed at the University hospital of Dijon, Burgundy, France. All patients scheduled for MIHS was included. Data was collected retrospectively. During this period, 20 patients had SAPB and 26 had CWI. SAPB was performed before extubation with a single injection of 0.5 mg/kg of ropivacaïne (5 mg/ml). In the CWI group, catheter was inserted in the subcutaneous space by the surgeon at the end of the procedure. A 10 ml bolus of ropivacaïne (7.5 mg/mL) was followed by a continuous infusion (2 mg/ml) between 7 and 12 ml/h for 48 h. Morphine consumption and visual analog score (VAS) were recorded for 48 h. Length of stay in intensive care unit and hospital was also collected., Results: Morphine consumption and VAS score were significantly lower in SAPB group (p < 0.01). Length of stay in intensive care and hospital was significantly was decreased in SAPB group., Conclusion: SAPB appears effective in reducing postoperative MIHS pain.

Non-alcoholic fatty liver disease (NAFLD) is commonly associated with obesity, metabolic syndrome, and type 2 diabetes. NAFLD is also seen in patients with endocrinopathies. However, the relationship between endocrine diseases and the development of NAFLD is not well known. In this study, we set out to determine whether liver fat content (LFC) was associated with IGF1 levels in people with pituitary diseases (PD). Eighty-nine patients with pituitary diseases and 74 healthy controls were included in this study. LFC was measured using MRI. Hepatic steatosis was defined as LFC>5.5%. Patients with PD were older, and had a higher BMI than healthy controls. LFC was significantly higher in people with PD than in controls (6.5% vs. 3.2%; p<0.001). LFC was negatively associated with the IGF1 level. The prevalence of steatosis was higher in PD patients than in controls (36.3% vs. 14.8%; p=0.002). In multivariate analysis, which included patients and controls, the predictive variables for steatosis were age, BMI and IGF1 levels, whereas the presence of pituitary diseases and gender were not associated with steatosis. Our data showed that LFC was strongly associated with IGF1 levels. These results suggest that steatosis associated with PD is probably a consequence of a low IGF1 level in these patients., Competing Interests: The authors declare that they have no conflict of interest., (© Georg Thieme Verlag KG Stuttgart · New York.)

Extracorporeal life support (ECLS) has shown benefits in the management of refractory in-hospital cardiac arrest (IHCA) by improving survival. Nonetheless, the results concerning out-of-hospital refractory cardiac arrests (OHCA) remain uncertain. The aim of our investigation was to compare survival between the two groups. We realized a single-center retrospective, observational study of all patients who presented IHCA or OHCA treated with ECLS between 2011 and 2015. Multivariate analysis was realized to determine independent factors associated with mortality. Over the 4-year period, 65 patients were included, 43 in the IHCA group (66.2%), and 22 (33.8%) in the OHCA group. The duration of low flow was significantly longer in the OHCA group (60 vs. 90 min, P = 0.004). Survival to discharge from the hospital was identical in the two groups (27% in the OHCA group vs. 23% in the IHCA group, P = 0.77). All surviving patients in the OHCA group had a cerebral performance categories score of 1-2. In multivariate analysis, we found that the initial lactate level and baseline blood creatinine were independently associated with mortality. We found comparable survival and neurological score in patients who presented IHCA and OHCA treated with ECLS. We believe that appropriate selection of patients and optimization of organ perfusion during resuscitation can lead to good results in patients with OHCA treated with ECLS., (© 2017 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.)

Purpose: In patients with aneurysmal subarachnoid hemorrhage (aSAH), acute cardiac dysfunction and triple-H-therapy, can lead to hypoxemia. Our aim was to assess impact of a protocoled fluid restrictive approach on hypoxemia in these patients., Methods: We included prospectively ICU patients with aSAH admitted within 24h after the bleed. The study was divided into 2 phases. The first phase, from January to December 2012, was designated as control group (group C). The second phase, from February 2014 to January 2015, was designated as study group (group S). Between these periods, a protocoled fluid intake approach was implemented to maintain as low as possible the cumulative fluid balances., Results: Effective fluid restriction was obtained: at day 3 cumulative fluid balances were respectively for group C and group S, 1559±2402ml and 759±1855ml (p=0.04); and 2211±4918ml vs 529±2806ml (p=0.04) at day 7. We observed reduction in proportion of hypoxemic patient in group S compared to group C, at day 3 (22% vs 40%, p=0.047) and at day 7 (28% vs 57%, p=0.007)., Conclusions: Fluid restrictive management of patients with aSAH decreases number of hypoxemic patients at day 3 and day 7., (Copyright © 2017 Elsevier Inc.

The increase use of immunosuppressive treatments in patients with solid cancer and/or inflammatory diseases requires revisiting our practices for the prevention of infectious risk in the care setting. A review of the literature by a multidisciplinary working group at the beginning of 2014 wished to answer the following 4 questions to improve healthcare immunocompromised patients: (I) How can we define immunocompromised patients with high, intermediate and low infectious risk, (II) which air treatment should be recommended for this specific population? (III) What additional precautions should be recommended for immunocompromised patients at risk for infection? (IV) Which global environmental control should be recommended? Based on data from the literature and using the GRADE method, we propose 15 recommendations that could help to reduce the risk of infection in these exposed populations., (Copyright © 2017 Elsevier Masson SAS.

Objective: To correlate dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) features to clinical and computed tomography (CT) morphological features of osteoid osteoma (OO)., Materials and Methods: Our institutional review board approved this retrospective study, waiving the need for informed consent. We included the 102 patients treated with interstitial laser ablation for histologically documented OO at our institution in 2008-2013. DCE-MRI variables were the time-enhancement pattern and rising slope (Slope rise ) and CT variables were the bone and segment involved (OO bone and OO segment, respectively), OO location relative to the native cortex (OO cortex ), nidus surface area, vessel sign, and largest neighboring-vessel diameter (Dmax vessel ). Descriptive statistics and correlations linking DCE-MRI findings to clinical and CT characteristics were computed., Results: DCE-MRI showed early arterial peak enhancement in 95 (93%) cases, with a mean Slope rise of 9.30 ± 8.10. CT visualized a vessel sign in 84 (82%) cases with a mean Dmax vessel of 1.10 ± 0.60 mm. By univariate analysis, Slope rise correlated significantly with pain duration and Dmax vessel (r = 0.30, P = 0.003; and r = 0.22, P = 0.03; respectively). Analysis of variance showed that Slope rise correlated significantly with OO bone (P < 0.001), with a steeper slope for OOs located in short or flat bones., Conclusion: This study suggests more abundant vascularization of OOs with long-lasting pain and location on short or flat bones.

Objectives: To compare transarterial chemoembolization (TACE)-related hepatic toxicities of conventional TACE (cTACE) and drug-eluting beads TACE (DEB-TACE) in patients with intermediate-stage hepatocellular carcinoma., Methods: In this retrospective study, 151 consecutive patients undergoing cTACE or DEB-TACE and MRI 3-6 weeks before and after therapy were included. Toxicity was assessed on imaging (global hepatic damages (GHD), overall biliary injuries, biliary cast, bile duct dilatation, intrahepatic biloma, portal thrombosis), and clinico-biological follow-ups. Tumour response, time to progression (TTP), and overall survival were assessed. Factors influencing complication rate were identified by generalized equation logistic regression model., Results: Biliary injuries and intrahepatic biloma incidence were significantly higher following DEB-TACE (p < 0.001). DEB-TACE showed a significant increased risk of GHD (OR: 3.13 [1.74-5.63], p < 0.001) and biliary injuries (OR: 4.53 [2.37-8.67], p < 0.001). A significant relationship was found between baseline prothrombin value and GHD, biliary injuries and intrahepatic biloma (all p < 0.01), and between the dose of chemotherapy and intrahepatic biloma (p = 0.001). Only TTP was significantly shorter following DEB-TACE compared to cTACE (p = 0.025)., Conclusions: DEB-TACE was associated with increased hepatic toxicities compared to cTACE. GHD, biliary injuries, and intrahepatic biloma were more frequently observed with high baseline prothrombin value, suggesting that cTACE might be more appropriate than DEB-TACE in patients with less advanced cirrhosis., Key Points: • DEB-TACE demonstrated more therapy-related hepatic locoregional complications compared to cTACE. • TACE-related hepatic locoregional toxicities occurred more frequently with high baseline PT value. • cTACE may be more appropriate in patients with high baseline PT value.

Introduction: Body identification is the cornerstone of forensic investigation. It can be performed using radiographic techniques, if antemortem images are available. This study was designed to assess the value of visual comparison of the computed tomography (CT) anatomical aspects of the sphenoid sinuses, in forensic individual identification, especially if antemortem dental records, fingerprints or DNA samples are not available., Material and Methods: This retrospective work took place in a French university hospital. The supervisor of this study randomly selected from the picture archiving and communication system (PACS), 58 patients who underwent one (16 patients) or two (42 patients) head CT in various neurological contexts. To avoid bias, those studies were prepared (anonymized, and all the head structures but the sphenoid sinuses were excluded), and used to constitute two working lists of 50 (42+8) CT studies of the sphenoid sinuses. An anatomical classification system of the sphenoid sinuses anatomical variations was created based on the anatomical and surgical literature. In these two working lists, three blinded readers had to identify, using the anatomical system and subjective visual comparison, 42 pairs of matched studies, and 16 unmatched studies. Readers were blinded from the exact numbers of matching studies., Results: Each reader correctly identified the 42 pairs of CT with a concordance of 100% [97.5% confidence interval: 91-100%], and the 16 unmatched CT with a concordance of 100% [97.5% confidence interval: 79-100%]. Overall accuracy was 100%., Conclusion: Our study shows that establishing the anatomical concordance of the sphenoid sinuses by visual comparison could be used in personal identification. This easy method, based on a frequently and increasingly prescribed exam, still needs to be assessed on a postmortem cohort., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Protracted bodily pain is a phenomenon that often affects a human being's whole life. Care of human beings with protracted pain is challenging because pain is not always measureable, and the experiences of pain are subjective, unique and shapeshifting. Therefore, the aim is to highlight what protracted bodily pain signifies for the human being, and human beings' experiences of what is caring in a context of protracted bodily pain. Four informants with protracted bodily pain took part in a focus group interview. The interview was analysed by using a qualitative content analysis with a hermeneutic approach. The findings show that protracted pain renders human beings speechless, limits and robs them of their lives. The pain is described as a domineering, unpleasant and unwelcome guest. The pain can change the human being's personality and creates feelings of guilt. Uncertainty about the origin of the pain as well as a nonchalant treatment or not being believed intensifies the pain. Human being experience mastering the pain, encounters with caregivers who can ease the burden, community with others and finding that little something extra in everyday life is experienced as caring. From a caring science perspective, the relation between protracted pain and suffering is obvious. Suffering emerges as illness suffering, as life suffering and as suffering caused by care. Professional as well as natural caring is important in a context of protracted bodily pain. The human being longs to encounter caregivers who are courageous enough to lay themselves on the line. Community with people who are prepared to share the burden eases the heavy burden that pain brings to life, it brings hope and relief., (© 2016 Nordic College of Caring Science.)

Fusarium oxysporum is typically a soilborne fungus but can also be found in aquatic environments. In hospitals, water distribution systems may be reservoirs for the fungi responsible for nosocomial infections. F. oxysporum was previously detected in the water distribution systems of five French hospitals. Sixty-eight isolates from water representative of all hospital units that were previously sampled and characterized by translation elongation factor 1α sequence typing were subjected to microsatellite analysis and full-length ribosomal intergenic spacer (IGS) sequence typing. All but three isolates shared common microsatellite loci and a common two-locus sequence type (ST). This ST has an international geographical distribution in both the water networks of hospitals and among clinical isolates. The ST dominant in water was not detected among 300 isolates of F. oxysporum that originated from surrounding soils. Further characterization of 15 isolates by vegetative compatibility testing allowed us to conclude that a clonal lineage of F. oxysporum circulates in the tap water of the different hospitals., Importance: We demonstrated that a clonal lineage of Fusarium oxysporum inhabits the water distribution systems of several French hospitals. This clonal lineage, which appears to be particularly adapted to water networks, represents a potential risk for human infection and raises questions about its worldwide distribution., (Copyright © 2016, American Society for Microbiology.

Group A rotavirus (RVA) is the leading cause of acute gastroenteritis in young children worldwide. A prospective surveillance network has been set up to investigate the virological and clinical features of RVA infections and to detect the emergence of potentially epidemic strains in France. From 2009 to 2014, RVA-positive stool samples were collected from 4800 children <5 years old attending the paediatric emergency units of 16 large hospitals. Rotaviruses were then genotyped by RT-PCR with regard to their outer capsid proteins VP4 and VP7. Genotyping of 4708 RVA showed that G1P[8] strains (62.2%) were predominant. The incidence of G9P[8] (11.5%), G3P[8] (10.4%) and G2P[4] (6.6%) strains varied considerably, whereas G4P[8] (2.7%) strains were circulating mostly locally. Of note, G12P[8] (1.6%) strains emerged during the seasons 2011-12 and 2012-13 with 4.1% and 3.0% prevalence, respectively. Overall, 40 possible zoonotic reassortants, such as G6 (33.3%) and G8 (15.4%) strains, were detected, and were mostly associated with P[6] (67.5%). Analysis of clinical records of 624 hospitalized children and severity scores from 282 of them showed no difference in clinical manifestations or severity in relation to the genotype. The relative stability of RVA genotypes currently co-circulating and the large predominance of P[8] type strains may ensure vaccine effectiveness in France. The surveillance will continue to monitor the emergence of new reassortants that might not respond to current vaccines, all the more so as all genotypes can cause severe infections in infants., (Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases.

We study the associations between apoA-II fractional catabolic rate (FCR) and the kinetics of VLDL subspecies and apoA-I and show that, in abdominally obese individuals, apoA-II FCR is positively and independently associated with both apoA-I FCR and VLDL1-TG indirect FCR.

Objectives: Ventilator-associated pneumonia is frequent in ICUs. Extended-spectrum β-lactamase-producing Enterobacteriaceae are difficult-to-treat pathogens likely to cause ventilator-associated pneumonia. We sought to assess the interest of screening for extended-spectrum β-lactamase-producing Enterobacteriaceae rectal carriage as a way to predict their involvement in ventilator-associated pneumonia., Design: A retrospective cohort study of patients with suspected ventilator-associated pneumonia in a medical ICU was conducted., Patients: Every patient admitted between January 2006 and August 2013 was eligible if subjected to mechanical ventilation for more than 48 hours. Each patient with suspected ventilator-associated pneumonia was included in the cohort. Active surveillance culture for extended-spectrum β-lactamase-producing Enterobacteriaceae detection was routinely performed in all patients at admission and then weekly throughout the study period. Extended-spectrum β-lactamase colonization was defined by the isolation of at least one extended-spectrum β-lactamase-producing Enterobacteriaceae from rectal swab culture., Interventions: None., Measurements and Main Results: Among 587 patients with suspected ventilator-associated pneumonia, 40 (6.8%) were colonized with extended-spectrum β-lactamase-producing Enterobacteriaceae prior to the development of pneumonia. Over the study period, 20 patients (3.4%) had ventilator-associated pneumonia caused by extended-spectrum β-lactamase-producing Enterobacteriaceae; of whom, 17 were previously detected as being colonized with extended-spectrum β-lactamase-producing Enterobacteriaceae. Sensitivity and specificity of prior extended-spectrum β-lactamase-producing Enterobacteriaceae colonization as a predictor of extended-spectrum β-lactamase-producing Enterobacteriaceae involvement in ventilator-associated pneumonia were 85.0% and 95.7%, respectively. The positive and negative predictive values were 41.5% and 99.4%, respectively. The positive likelihood ratio was 19.8., Conclusions: Screening for extended-spectrum β-lactamase-producing Enterobacteriaceae digestive colonization by weekly active surveillance cultures could reliably exclude the risk of the involvement of such pathogens in patients with ventilator-associated pneumonia in low-prevalence area.

To determine whether rotavirus infections are linked to secretor status, we studied samples from children in Tunisia with gastroenteritis. We phenotyped saliva for human blood group antigens and tested feces for rotavirus. Rotavirus was detected in 32/114 patients. Secretor genotyping showed that P[8] rotavirus infected secretors and nonsecretors, and infection correlated with presence of Lewis antigen.

Noroviruses (NoVs) constitute a major cause of gastroenteritis in Tunisia. One hundred and fourteen matched saliva and stool samples were collected from children (n = 114) suffering from acute gastroenteritis at the hospital of Monastir during the winter season 2011-2012. For 98 of 114 children, blood samples were collected for secretor genotyping. NoVs were associated with 36.8% (n = 42/114) of the gastroenteritis cases. The GII.3 genotype was the most common (69% of all NoVs). For patients who were phenotyped (n = 114) for human blood group antigens (HBGAs), the secretor and non-secretor phenotypes represented 79% and 21%, respectively. Of the NoV infections, 83% were detected in all ABO groups. Five GII.3 isolates, one GII.1 isolate and one GII.7 isolate were detected in Lewis-positive non-secretors, confirmed by genotyping of the FUT2 gene. Even though our data showed that GII.3 NoVs could infect non-secretors, no binding was observed with saliva and GII.3 baculovirus-expressed virus-like particles from the same symptomatic non-secretor individual. This suggests that other factors might also participate in NoV attachment in children and newborns., (Copyright © 2015 European Society of Clinical Microbiology and Infectious Diseases.

Purpose: To determine whether a mono-, bi- or tri-exponential model best fits the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) signal of normal livers., Materials and Methods: The pilot and validation studies were conducted in 38 and 36 patients with normal livers, respectively. The DWI sequence was performed using single-shot echoplanar imaging with 11 (pilot study) and 16 (validation study) b values. In each study, data from all patients were used to model the IVIM signal of normal liver. Diffusion coefficients (Di ± standard deviations) and their fractions (fi ± standard deviations) were determined from each model. The models were compared using the extra sum-of-squares test and information criteria., Results: The tri-exponential model provided a better fit than both the bi- and mono-exponential models. The tri-exponential IVIM model determined three diffusion compartments: a slow (D1 = 1.35 ± 0.03 × 10(-3) mm(2)/s; f1 = 72.7 ± 0.9 %), a fast (D2 = 26.50 ± 2.49 × 10(-3) mm(2)/s; f2 = 13.7 ± 0.6 %) and a very fast (D3 = 404.00 ± 43.7 × 10(-3) mm(2)/s; f3 = 13.5 ± 0.8 %) diffusion compartment [results from the validation study]. The very fast compartment contributed to the IVIM signal only for b values ≤15 s/mm(2) CONCLUSION: The tri-exponential model provided the best fit for IVIM signal decay in the liver over the 0-800 s/mm(2) range. In IVIM analysis of normal liver, a third very fast (pseudo)diffusion component might be relevant., Key Points: • For normal liver, tri-exponential IVIM model might be superior to bi-exponential • A very fast compartment (D = 404.00 ± 43.7 × 10 (-3) mm (2) /s; f = 13.5 ± 0.8 %) is determined from the tri-exponential model • The compartment contributes to the IVIM signal only for b ≤ 15 s/mm(2).

Members of the Fusarium group were recently detected in water distribution systems of several hospitals in the world. An epidemiological investigation was conducted over 2 years in hospital buildings in Dijon and Nancy (France) and in non-hospital buildings in Dijon. The fungi were detected only within the water distribution systems of the hospital buildings and also, but at very low concentrations, in the urban water network of Nancy. All fungi were identified as Fusarium oxysporum species complex (FOSC) and Fusarium dimerum species complex (FDSC) by sequencing part of the translation elongation factor 1-alpha (TEF-1α) gene. Very low diversity was found in each complex, suggesting the existence of a clonal population for each. Density and heterogeneous distributions according to buildings and variability over time were explained by episodic detachments of parts of the colony from biofilms in the pipes. Isolates of these waterborne populations as well as soilborne isolates were tested for their ability to grow in liquid medium in the presence of increasing concentrations of sodium hypochlorite, copper sulfate, anti-corrosion pipe coating, at various temperatures (4°-42 °C) and on agar medium with amphotericin B and voriconazole. The waterborne isolates tolerated higher sodium hypochlorite and copper sulfate concentrations and temperatures than did soilborne isolates but did not show any specific resistance to fungicides. In addition, unlike waterborne isolates, soilborne isolates did not survive in water even supplemented with glucose, while the former developed in the soil as well as soilborne isolates. We concluded the existence of homogeneous populations of FOSC and FDSC common to all contaminated hospital sites. These populations are present at very low densities in natural waters, making them difficult to detect, but they are adapted to the specific conditions offered by the complex water systems of public hospitals in Dijon and Nancy and probably other localities in the world., (Copyright © 2015 Elsevier Ltd.

Urine from urine-diversion toilets (UDTs) is routinely used as fertilizer for urban agriculture in Ouagadougou, Burkina Faso. Because urine from UDTs can be accidentally spoiled by feces, we determined whether virulent enteric viruses could persist in urine that is used for agricultural purposes and pose a threat to human health. Urine samples (N = 60) were first collected from 42 UDTs during the months of January and February 2012 in Ouagadougou and screened negative for the presence of norovirus (NoV) and group A rotavirus (RV). Composite urine from five collection sites was used to determine whether spiked murine norovirus (MNV) and group A bovine rotavirus (boRVA) could remain infectious at 15, 25, and 42 °C over an incubation period of 42 days in phosphate buffered saline (control) and urine. For both viruses, infectivity was determined by plaque assay and the presence of viral genome was evaluated by real-time RT-PCR. A decrease in the infectious titer was observed in composite urines that were experimentally seeded with MNV and boRVA. The decrease in the infectious titer was greater for MNV than for boRVA. Given that MNV was more labile to urine than boRVA was, MNV and boRVA genomes were still detectable after the 42 and 49 days incubation period for MNV and boRVA, respectively. Our data using substitutes of human NoV and RV suggested that there is a virucidal activity of urine against RVs and NoVs, given that the effect was lesser for RV. In spite of disappointing results for boRVA, the use of urine as fertilizer is still promising provided that future safety studies are extended to other enteric viruses.

Objectives: To estimate the internal consistency, test-retest reliability and comparability of paper and computer versions of the Finnish version of the Tampa Scale of Kinesiophobia (TSK-FIN) among patients with chronic pain. In addition, patients' personal experiences of completing both versions of the TSK-FIN and preferences between these two methods of data collection were studied., Design: Test-retest reliability study. Paper and computer versions of the TSK-FIN were completed twice on two consecutive days., Participants: The sample comprised 94 consecutive patients with chronic musculoskeletal pain participating in a pain management or individual rehabilitation programme. The group rehabilitation design consisted of physical and functional exercises, evaluation of the social situation, psychological assessment of pain-related stress factors, and personal pain management training in order to regain overall function and mitigate the inconvenience of pain and fear-avoidance behaviour., Results: The mean TSK-FIN score was 37.1 [standard deviation (SD) 8.1] for the computer version and 35.3 (SD 7.9) for the paper version. The mean difference between the two versions was 1.9 (95% confidence interval 0.8 to 2.9). Test-retest reliability was 0.89 for the paper version and 0.88 for the computer version. Internal consistency was considered to be good for both versions. The intraclass correlation coefficient for comparability was 0.77 (95% confidence interval 0.66 to 0.85), indicating substantial reliability between the two methods., Conclusion: Both versions of the TSK-FIN demonstrated substantial intertest reliability, good test-retest reliability, good internal consistency and acceptable limits of agreement, suggesting their suitability for clinical use. However, subjects tended to score higher when using the computer version. As such, in an ideal situation, data should be collected in a similar manner throughout the course of rehabilitation or clinical research., (Copyright © 2014 Chartered Society of Physiotherapy.

Aim: This retrospective study aimed to compare the efficacy of and tolerance to two center-related conventional transarterial chemoembolization (TACE) strategies in the management of unresectable hepatocellular carcinoma (HCC)., Patients and Methods: All HCC patients in whom TACE was initiated in the two centers from June 2008 to July 2011 were included. The TACE strategy performed in center 1 was "on demand" with selective injections of idarubicin, whereas the TACE strategy in center 2 was based "on scheduled" non-selective injections of epirubicin. Toxicity was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events v4.0., Results: One hundred and fifty HCC patients were included. Median time to treatment failure was significantly higher in center 1, 13.1 months vs. 7.9 months in center 2 (hazard ratio, 2.32; p<10-3 in multivariate analysis). Median overall survival was 21.1 months in center 1 vs. 18.4 months in center 2 (p=NS). The proportion of grade ≥ 3 adverse events and mean hospitalisation duration for the overall TACE treatment were significantly greater in center 2 than in center 1: 56% vs. 32% (p<0.01) and 14.2 ± 7.2 days vs. 10.3 ± 7.0 days (p<0.01), respectively., Conclusion: Our results failed to show any significant survival differences between two center-related TACE strategies but showed a significantly smaller proportion of grade ≥ 3 adverse events and shorter hospitalisation for the overall treatment when the "on-demand" strategy was used., (Copyright© 2014 International Institute of Anticancer Research (Dr. John G.

Norovirus (NoV) is one of the main causative agents of acute gastroenteritis worldwide. In temperate climates, outbreaks peak during the winter season. The mechanism by which climatic factors influence the occurrence of NoV outbreaks is unknown. We hypothesized that humidity is linked to NoV seasonality. Human NoV is not cultivatable, so we used cultivatable murine norovirus (MNV) as a surrogate to study its persistence when exposed to various levels of relative humidity (RH) from low (10% RH) to saturated (100% RH) conditions at 9 and 25°C. In addition, we conducted similar experiments with virus-like particles (VLPs) from the predominant GII-4 norovirus and studied changes in binding patterns to A, B, and O group carbohydrates that might reflect capsid alterations. The responses of MNV and VLP to humidity were somewhat similar, with 10 and 100% RH exhibiting a strong conserving effect for both models, whereas 50% RH was detrimental for MNV infectivity and VLP binding capacity. The data analysis suggested that absolute humidity (AH) rather than RH is the critical factor for keeping NoV infectious, with an AH below 0.007 kg water/kg air being favorable to NoV survival. Retrospective surveys of the meteorological data in Paris for the last 14 years showed that AH average values have almost always been below 0.007 kg water/kg air during the winter (i.e., 0.0046 ± 0.0014 kg water/kg air), and this finding supports the fact that low AH provides an ideal condition for NoV persistence and transmission during cold months., (Copyright © 2014, American Society for Microbiology.

Background: Invasive candidiasis (IC) is a life-threatening ICU-acquired infection. A strong correlation between time to antifungal therapy (AFT) administration and outcome has been established. Empirical therapy benefit should be balanced with the risk of echinocandin overuse. We assessed therefore a decision rule that aimed at guiding empirical therapy., Methods: A 45-month prospective cohort study in a teaching medical ICU. All of the patients with suspected IC (uncontrolled sepsis despite broad spectrum antibiotics without any bacterial proven infection in patients with Candida score ≥ 3 points including multifocal Candida sp. colonization) were eligible. The primary endpoint was proven IC diagnosis (i.e., candidemia) following treatment onset. Timing of AFT administration was also investigated in those latter patients. Antifungal therapy step-down and discontinuation was done according to international guidelines in patients with candidemia. Otherwise, echinocandin discontinuation was encouraged in patients without proven IC, excepting when a clinical improvement was achieved without any other explanation that antifungals initiation (i.e., probable IC). In addition, a survival multivariate analysis using a Cox model was conducted., Results: Fifty-one patients were given an echinocandin with respect to our decision rule. Among them, candidemia was diagnosed thereafter in 9 patients. Over the same period, antifungal therapy was triggered by candidemia announcement (i.e., definite therapy) in 12 patients who did not fulfill criteria for empirical therapy before. Time elapsed from candidemia onset to echinocandin therapy initiation was shortened (0.4 [0.5] vs. 2.4 [2.8] hours; p = 0.04) when it was given empirically. In addition, 18 patients clinically improved under empirical antifungal therapy without any obvious other explanation, despite IC remained unproven. Moreover, echinocandin exposure duration was independently related to survival in those patients. Over the same period, our predefined criteria for empirical therapy were overruled in 55 cases. None of them develop IC thereafter. Finally, Our decision rule allowed IC early recognition of proven/probable IC with sensitivity, specificity, positive and negative predictive value of 69.2%, 82.1%, 69.2% and 82.1%, respectively., Conclusion: Implementation of pragmatic guidelines for empirical AFT based on CS and fungal colonization assessment could be useful in selecting patients who really benefit from an echinocandin.

Purpose: To evaluate and compare macular pigment optical density (MPOD) measurements obtained using the modified Heidelberg Retina Angiograph (HRA) and the Visucam 200., Methods: Healthy young subjects were included in this prospective study. MPOD was measured with the modified HRA at 0° and 0.5°, 1°, 2°, and 6° eccentricities from the fovea. The parameters obtained with the Visucam 200 (maximum, mean, area, and volume) were recorded the same day on the same subjects. Intraclass correlation coefficients (ICCs) and correlation coefficients were used to evaluate the agreement between the two devices. The repeatability and the reproducibility of each method were also assessed., Results: Sixty-seven subjects were included whose median (interquartile ratio) age was 25 years (range, 23-30 years). The MPODs as measured with the modified HRA were higher than those measured with the Visucam 200 (P < 0.0001). The ICCs were low, ranging from 0.020 to 0.188. The correlation coefficients between the two methods were very low and ranged from 0.05 to 0.22. Repeatability and reproducibility were good with both methods, with ICCs ranging from 0.697 to 0.923., Conclusions: Agreement between the modified HRA and the Visucam in measuring MPOD was rather low. These results suggest that the two methods are not interchangeable. Before using the Visucam 200 in clinical and research setting, further evaluation seems mandatory (http://ansm.sante.fr/ number, 2009-A00448-49).

Introduction: Ventilator-associated pneumonia (VAP) is the most commonly acquired infection in intensive care units (ICU). Its outcome is related, at least in part, to the host's response. Statins have anti-inflammatory effects and may thus improve the outcome. We aimed to assess the impact of prior statin use in the setting of VAP., Methods: A six-year cohort study was conducted in a French ICU at a teaching hospital. All of the patients with suspected VAP were included. Baseline characteristics, outcomes, statin exposure, and the description of suspected episodes were collected prospectively. The primary endpoint was 30-day mortality. Patients who were taking statins before admission to the ICU whether or not treatment was continued thereafter ('previous users' group) were compared to those without prior statin therapy ('statin-naive' group). A survival analysis using a Cox model was conducted in the whole cohort and in the subgroup of prior statin users., Results: Among the 349 patients included, 93 (26.6%) had taken statins. At baseline, these patients were at higher risk of complications than statin-naive ones (for example, older, more likely to be men and to have underlying diseases, greater simplified acute physiology score II (SAPS II)). There was, however, no difference regarding severity at the time VAP was suspected (sequential organ failure assessment (SOFA): 9.0 (4.0 to 16.0) versus 8.0 (4.0 to 17.0); P = 0.11). Nonetheless, 30-day mortality in statin users was not different from that in statin-naive patients (35.5% versus 26.2%, respectively; adjusted hazard ratio (HR) = 1.23 (0.79 to 1.90) 95% confidence interval (CI); P = 0.36). In contrast, after limiting analysis to prior statin users and adjusting for potential confounders, those who continued the treatment had better survival than those who did not (HR = 0.47; (0.22 to 0.97) 95% CI; P = 0.04)., Conclusions: Statin continuation in prior users could provide protective effects in patients with suspected VAP.

Background: Several recent studies have shown some discrepancies between 25-hydroxyvitamin D [25(OH)D] assay methods, despite some improvement in the past few years. The accuracy of 25(OH)D assay methods is still a real challenge for clinical laboratories. The aim of this study was to assess the agreement between a large panel of routine assays and a two-dimensional liquid chromatography/tandem mass spectrometry (2D LC-MS/MS) method, selected as the reference method., Methods: Forty-nine human plasma samples with only endogenous 25(OH)D₃ were analyzed with 11 different methods, especially with three LC-UV methods that differed in the extraction step. Seven routine immunoassays were also tested: two manual (RIA and EIA from IDS) and five fully-automated methods. The results of the 25(OH)D₃ assays were compared with those of the 2D LC-MS/MS method using weighted Deming regression analysis, Bland-Altman plots and concordance correlation coefficient (CCC). The ability of these methods to properly classify patients was evaluated by sorting results depending on vitamin D status., Results: The CCC was >0.90 for the three LC-UV methods and for most of the automated IA, meaning substantial agreement with 2D LC-MS/MS results. The ability to properly classify patients according to their vitamin D status was overall satisfactory for most of the methods tested (concordance >90%)., Conclusions: The immunoassays available on Liaison, Isys, Architect and Elecsys, together with our in-house LC-UV method preceded by an SLE step met the minimum requirements for the assessment of vitamin D status in clinical laboratories.

Purpose: The purpose of our study is to determine whether there is a relation between overweight, age, sex, "hospitalised/outpatient" status and a non-inflammatory hypersignal of the subcutaneous lumbosacral adipose tissue in T2 Short-Tau Inversion-Recovery (T2-STIR) MR imaging sequences., Patients and Methods: One hundred and six lumbar MRI, including a T2-STIR and T1 Fluid Attenuated Inversion-Recovery (FLAIR) weighted sagittal sequences, were retrospectively taken from the picture archiving and communication system (PACS) of our hospital and then made anonymous and analysed. The presence or absence of a T2-STIR hypersignal within subcutaneous adipose tissue behind the paraspinal muscle aponeurosis was determined. In addition, the weight, thickness of the fat tissue, the administrative status of the patient, the age, sex, time of the examination and, when present, the height of this hypersignal were noted. A uni- and multivariate analysis by logistic regression was carried out in order to examine the relationship between the data gathered., Results: In the examinations selected, 25.5% (n=27) demonstrated a T2-STIR hypersignal in the subcutaneous tissue. We identified the weight (P<0.023), thickness of the fat tissue (P<0.001), the age of the patient (P<0.017) and the "hospitalised" status (P<0.009) as significant variables associated with this T2-STIR hypersignal. The mean height of the hypersignal was 109.5mm. Five of the 27 patients had an injection of gadolinium chelate and no enhancement was found at this level., Conclusion: We found a significant link between overweight, age and "hospitalised" status and the non-inflammatory infiltration of lumbar adipose tissue. This phenomenon seems to correspond with an interstitial oedema, related to subcutaneous stasis. This anomaly should not be confused with a local inflammation., (Copyright © 2013 Éditions françaises de radiologie. Published by Elsevier Masson SAS. All rights reserved.)

Small supernumerary marker chromosomes (sSMCs) are structurally abnormal chromosomes that cannot be characterized by karyotype. In many prenatal cases of de novo sSMC, the outcome of pregnancy is difficult to predict because the euchromatin content is unclear. This study aimed to determine the presence or absence of euchromatin material of 39 de novo prenatally ascertained sSMC by array-comparative genomic hybridization (array-CGH) or single nucleotide polymorphism (SNP) array. Cases were prospectively ascertained from the study of 65,000 prenatal samples [0.060%; 95% confidence interval (CI), 0.042-0.082]. Array-CGH showed that 22 markers were derived from non-acrocentric markers (56.4%) and 7 from acrocentic markers (18%). The 10 additional cases remained unidentified (25.6%), but 7 of 10 could be further identified using fluorescence in situ hybridization; 69% of de novo sSMC contained euchromatin material, 95.4% of which for non-acrocentric markers. Some sSMC containing euchromatin had a normal phenotype (31% for non-acrocentric and 75% for acrocentric markers). Statistical differences between normal and abnormal phenotypes were shown for the size of the euchromatin material (more or less than 1 Mb, p = 0.0006) and number of genes (more or less than 10, p = 0.0009). This study is the largest to date and shows the utility of array-CGH or SNP array in the detection and characterization of de novo sSMC in a prenatal context., (© 2013 John Wiley & Sons A/S.

Recent studies of long-distance migratory birds show that behavioural and physiological changes associated with predictable or unpredictable challenges during the annual cycle are distinctively regulated by hormones. Corticosterone is the primary energy regulating hormone in birds. Corticosterone levels are elevated during stresses but they are also modulated seasonally according to environmental conditions and life-history demands. We measured the baseline and stress-induced levels of corticosterone in the barn swallow (Hirundo rustica L.) just before spring and autumn migrations in South Africa and Finland, respectively. Barn swallows completing their pre-breeding moult had low body condition (residual body mass) and high baseline corticosterone levels in the wintering grounds. In contrast, baseline corticosterone levels in Finland were low and not related to residual mass. These data contradict the first prediction of the migration modulation hypothesis (MMH) by showing no association with baseline corticosterone levels and pre-migratory fuelling. Yet, the adrenocortical response to the capture and handling stress was notably blunted in South Africa compared to a strong response in Finland. Further, individuals that had started fuelling in Finland showed a reduced response to the handling stress. Taken together, elevated baseline corticosterone levels and high residual mass may blunt the adrenocortical response in long-distance migrants and aerial feeders such as the barn swallow. This observation lends support to the second prediction of the MMH.

Profilaggrin (proFLG) and its processing products are critical to the health and appearance of skin. The recent identification of loss-of-function filaggrin (FLG) mutations as a predisposing factor in ichthyosis vulgaris and atopic dermatitis has lead to a resurgent interest in this enigmatic protein. Here, we review the literature on the structure and many functions of proFLG, from its role as a filament-aggregating protein and a source of natural moisturizing factor (NMF), to the more recent discoveries of its role in epidermal barrier formation and its more speculative functions as an antimicrobial and sunscreen. Finally, we discuss the relationship of proFLG with dry skin, the influence of moisturizers on NMF generation and speculate on next generation of FLG research., (© 2013 Society of Cosmetic Scientists and the Société Française de Cosmétologie.)

Objectives: To assess human papillomavirus prophylactic vaccine coverage among a representative population of French girls, aged 14 years and above, attending middle and high schools, and to determine factors associated with the initiation and completion of the vaccination protocol., Study Design: This cross-sectional study, designed with cluster sampling, was conducted from October 2010 to May 2011, in 29 schools in the department of Côte d'Or, France. The schools were randomized according to their status (public or private) and location (rural or urban). Two classes per level were then included. All analyses were stratified on age., Results: 948 questionnaires were collected (87.9% participation). Mean age was 15.2 years (SD=1.3), ranging between 14 and 19. Only 31.7% of 14-year-old girls and 61.4% of girls aged 15 and above initiated vaccination (one dose), and 7.8% of 14-year-old girls and 48.5% of girls aged 15 and above completed it (three doses). An urban school location and a physician's recommendation were independently associated with vaccination initiation in girls aged 14. In girls aged 15 and above, the parents' socioeconomic status, the family composition and a recommendation by a physician were independently associated with vaccination initiation. Once vaccination had been initiated, girls who attended private school, who belonged to families with higher outcomes, who lived with a single parent or who smoked were less likely to complete the vaccination protocol., Conclusion: HPV prophylactic vaccine coverage in girls attending school in Côte d'Or appears to be low. Physicians play a major role in vaccine acceptance., (Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.)

Background: The surveillance of methicillin-resistant Staphylococcus aureus (MRSA) is a national priority. The rate of MRSA infections is one of six indicators tracked by the Department of Health. Since 2002, the French institute for public health surveillance (InVS) has monitored MRSA infections to estimate incidence density. Today, the use of the French administrative database (PMSI) could facilitate this surveillance. The aim of this study was to compare MRSA incidence density computed at a national level using PMSI databases with the results from the InVS taken as the reference., Methods: PMSI databases for the years 2006 to 2009 were used. The reference results were those published by the InVS from 2006 to 2009. MRSA density defined as the number of MRSA infections recorded per year over 1000 hospital stays was computed. It was then compared with the MRSA incidence density measured by InVS. The time course of MRSA incidence in the PMSI records was modeled using a Poisson regression., Results: The incidence density measured by the InVS was higher than the MRSA density computed using the PMSI, but this difference appeared to decrease over time. The PMSI density/InVS MRSA incidence density ratio was 0.8% in 2006 and about 9.2% in 2009. We observed inverted trends with a growing trend in MRSA density identified by the PMSI. Furthermore, the year of study was significantly associated with incidence density (P=0.01)., Conclusion: Using PMSI data as an additional source of information in the hospital MRSA surveillance process makes it possible to detect and analyze patient repeats at the regional and national levels with linkage facilities. Estimation of incidence density for hospitals not participating to this surveillance system will be the next step., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

In Finland, policy requirements have demanded providers to work collaboratively together with regard to intimate partner violence (IPV). This research and development project seeks to identify efficient tools for stopping IPV. The project included staff training to recognize and respond to IPV, the development of a research-based guideline for use in the care situations of victims and perpetrators and the integration of the guideline into practices and staff development. Networking was developed during the project through interprofessional and multiagency collaboration, whereas appraisal information was collected at different stages of the process. This paper focuses on the issues of interprofessional collaboration, and uses psychiatric care as an example. There is some evidence that interprofessional interventions reduce the cost of patient care and improve the quality of IPV services. That is why it is important to discuss these issues and solve possible problems arising in interprofessional patient care.

Objective: To assess the functional and anatomical outcome of primary vitrectomy without scleral buckling for rhegmatogenous retinal detachment (RRD) in highly myopic eyes with axial length over 30 mm., Methods: In this retrospective, interventional case series, we evaluated the outcome of primary vitrectomy without scleral buckling in 67 highly myopic patients (67 eyes) with RRD. Anatomical success rate was defined as complete reattachment of the retina without definitive silicone oil tamponade., Results: Retinal reattachment was achieved with a single surgery in 49 of 67 eyes (73.1%) and after 2 or 3 surgeries in 54 eyes (80.6%). The characteristics of retinal tears did not influence the final outcome. Multivariate analysis revealed that a longer axial length was the only factor associated with a higher failure rate, p = 0.0061. Mean preoperative visual acuity significantly increased after surgery, p = 0.0003., Conclusion: The study demonstrated fair efficacy of vitrectomy and fluid-gas exchange in the treatment of retinal detachment in highly myopic eyes with an axial length over 30 mm.

Group A rotaviruses are a leading cause of neonatal calf diarrhoea worldwide and prevention of this disease includes vaccination against these viruses. In order to highlight the potential selection of rotavirus genotypes due to immune pressure driven by vaccination, the aim of this study was to compare group A rotavirus genotypes circulating in French diarrhoeic calves in rotavirus vaccinated herds (G6P[5] vaccine) with those in non-vaccinated herds during one calving season in 2010. This study showed a high prevalence of rotavirus in both groups with no significant difference between the two. No significant differences regarding G, P and G/P rotavirus genotype distribution between the two groups were observed, with G6, P[5] and G6P[5] genotypes being by far the most prevalent. Moreover, sequence analyses of the VP7 and VP4 partial coding genes of the G6P[5] strains from this study did not allow us to distinguish them according to their origin. This study also showed that other pathogens responsible for calf diarrhoea, such as genogroup III noroviruses and neboviruses, were not more frequently associated with calf diarrhoea in vaccinated herds. Altogether, these results suggest that the studied vaccine did not promote the emergence of rotavirus genotypes or variants different from those of the vaccine or other viruses responsible for calf diarrhoea, such as caliciviruses., (Copyright © 2013 Elsevier Ltd.

The virucidal efficacy of a pulsed light treatment applied to viral suspensions, glass beads and herb powders was studied for the F-RNA bacteriophage MS2. The experimental results obtained demonstrated the high potential of this technology to efficiently decontaminate simple matrices but underlined the complexity of application to complex food matrices.

Purpose: The aim of our study was to assess the results and cost of a treatment strategy involving transarterial chemoembolisation with drug eluting beads (DEB-TACE) in patients with unresectable non-metastatic hepatocellular carcinoma (HCC)., Patients and Methods: This study included all patients treated with DEB-TACE in our hospital between January 2009 and December 2010. All patients received DEB-TACE on demand and were evaluated after each session., Results: Twenty-one patients received an average of 1.3 sessions. The median time to treatment discontinuation and median progression-free survival was 181 days and 295 days, respectively. Toxicity caused treatment discontinuation in three patients (14%). For the hospital, the average direct cost of treatment was €6,033 according to the analytical accounting system vs. €4,558 according to the official tariffs from the new French Diagnosis-Related Group prospective payment system (P=0.002)., Conclusion: In the treatment of HCC, on-demand DEB-TACE stabilises the disease in some patients but has not yet been thoroughly evaluated., (Copyright © 2012 Éditions françaises de radiologie.

The purpose of this study is to evaluate the prevalence of musculoskeletal pain and the use of analgesics in two random cohorts of home-dwelling older people 10 years apart (1999 (N = 2044) and 2009 (N = 1610)) in Helsinki, Finland, and to explore which patients characteristics are associated with potential undertreatment or overtreatment of pain. In 1999, the prevalence of daily joint pain interfering with functioning was 16.4% and that of back pain 13.9% among 75-85-year-old people, the respective figures being 21.9% and 17.1% in 2009 (p < 0.001). The proportion of those patients suffering from joint pain and using prescribed analgesics for that was 35.5% in 1999 and 41.5% in 2009 (p < 0.001). The corresponding figures for patients suffering from back pain with analgesics were 38.2% and 48.2% (p < 0.001), respectively. In 2009, 66.1% suffered from any musculoskeletal pain and 28.7% of them were prescribed analgesics, the figures being more frequent among women than men. In addition to higher age, female gender, and painful conditions, also psychiatric symptoms and dizziness tended to be independently associated with analgesic prescriptions. Among persons not reporting pain (N = 545) psychiatric symptoms were overrepresented in the group using prescribed analgesics (22.4% vs. 8.1%, p < 0.05). In conclusion, musculoskeletal pain is still clearly undertreated, but the coverage has increased during 10 years. In addition to pain, several patient characteristics, functioning and psychiatric symptoms, especially, were associated with analgesic prescriptions., (Copyright © 2012 Elsevier Ireland Ltd.

The aim of this study was to develop an improved technique for DNA extraction from 1 ml of uncultured AF from patients with a gestational age less than 16 weeks and to allow the use of array-CGH without DNA amplification. The DNA extraction protocol was tested in a series of 90 samples including 41 of uncultured AF at less than 16 weeks of gestation. Statistical analyses were performed using linear regression. To evaluate the sensitivity and the specificity of array-CGH on 1 ml of uncultured AF, five samples with an abnormal karyotype (three with aneuploidy, two with structural abnormalities) and five with a normal karyotype were studied. This protocol was reproducible and we were able to show a great improvement with higher yield of DNA obtained from all patients, including those with a gestational age less than 16 weeks (p = 0.003). All chromosomal abnormalities were detected and characterized by array-CGH and normal samples showed normal profiles. This new DNA extraction protocol associated with array-CGH analysis could be used in prenatal testing even when gestational age is less than 16 weeks, especially in cases with abnormal ultrasound findings.

Objective: Retinol-binding protein 4 (rbp4) is an adipokine secreted by adipocytes and liver, whose levels are elevated in type 2 diabetes mellitus (T2DM). Plasma levels of rbp4 and triglycerides are strongly correlated in T2DM. However, we do not know whether this association is direct or indirect via liver fat content, and the link between rbp4 and triglyceride metabolism remains unknown., Methods and Results: Liver fat measurement by proton spectroscopy was performed in 221 patients with T2DM, and an in vivo kinetic study with stable isotopes was carried out in 14 patients with T2DM. In multivariate analysis, triglycerides were associated positively with rbp4 (β=0.273, P<0.0001), apolipoprotein (apo) B (β=0.258, P<0.0001), and liver fat (β=0.191, P=0.002) and negatively with high-density lipoprotein cholesterol (β=-0.442, P<0.0001). rbp4 was correlated positively with apoB100 very-low-density lipoprotein (VLDL) pool (r=0.62, P=0.017) and negatively with VLDL-apoB100 total fractional catabolic rate (r=-0.66, P=0.001). In multivariate analysis, rbp4 (P=0.015), plasma triglycerides (P=0.024), and sex (P=0.026) were independently associated with VLDL-apoB100 total fractional catabolic rate., Conclusions: In T2DM, plasma rbp4 level is associated with plasma triglycerides, independently of liver fat content. There is a strong independent negative correlation between plasma rbp4 and VLDL-apoB100 total fractional catabolic rate. These data suggest that rbp4 may be involved in the pathophysiology of hypertriglyceridemia in T2DM by reducing VLDL catabolism.
