Purpose: Determining the attributes of effective business teachers is critical to schools as they strive to attract and retain students, assure learning, obtain and maintain reputation and accreditations, and place their alumni in the competitive job market. The purpose of this paper is to examine students and faculty perceptions of teaching effectiveness in five culturally disparate countries: Colombia, France, Lebanon, Sweden, and the USA. Design/methodology/approach: A survey was designed based on previous research complemented by an extensive literature review as well as personal communications with faculty in different international business schools. The survey considered 39 teaching attributes related to three specific dimensions: class delivery, class preparation and design, and instructional traits and personal characteristics. The survey targeted students and faculty from seven business schools located in five countries. Findings: This study offers new conceptual and analytical analyses from a cross-country comparative perspective. Rankings of the importance of perceived teaching attributes for both major groups involved in the teaching of business, faculty and students, are reported. The attributes are also ranked by teaching taxonomy and examined across countries. Practical implications:This study provides practical results that can be useful to instructors wishing to increase their teaching effectiveness and to universities considering revising their student evaluation forms. Originality/value: This study includes data collected from faculty and students from several schools located in culturally disparate countries and, thus, increases the applicability of the results in a cross-cultural manner and provides implications for practice internationally.

The evolutionary rationale offered by Bowlby implies that secure base relationships are common in child-caregiver dyads and thus, child secure behavior observable across diverse social contexts and cultures. This study offers a test of the universality hypothesis. Trained observers in nine countries used the Attachment Q-set to describe the organization of children's behavior in naturalistic settings. Children (N = 547) were 10-72 months old. Child development experts (N = 81) from all countries provided definitions of optimal child secure base use. Findings indicate that children from all countries use their mother as a secure base. Children's organization of secure base behavior was modestly related to each other both within and across countries. Experts' descriptions of the optimally attached child were highly similar across cultures.

Meeting the European Commission's 'Fit for 55' climate goals by the year 2030 in the context of the trilemma of security of supply, environmental sustainability, and competitiveness will require concerted efforts from the Member States on all fronts. Among others, it will require optimised techno-economic solutions that offer sustainable decarbonisation pathways for the concurrent decarbonisation of many sectors of the economy. This paper attempts to provide empirical evidence of the 'rooftop solar PV+EV concept' efficacy as a promising pathway to decarbonise France's transport, power and building sectors concurrently. Using the System Advisor Model (SAM), we find that if rooftop solar PV is installed on half of the available roof space, and if half of the passenger vehicle owners replace their internal combustion engine vehicles (ICEVs) with EVs by 2030, then France can meet 20 %–42 % of total electricity demand in the three most populous cities. Moreover, the solar PV + EV coupling can reduce CO 2 emissions from passenger vehicle use and electricity generation by 43 %–48 %. Also, the coupling can be a potentially worthwhile investment with a payback period of 2–3 years, a levelised cost of energy (LCOE) of about €0.04/kWh, and a net present value (NPV) of €6–19 billion without a feed-in tariff. We analyse the potential implementation challenges of the 'rooftop solar PV + EV concept' and propose some solutions. Finally, we argue that coupling rooftop solar PV + EV in cities is a cost-effective strategy to decarbonise urban energy, transport and building sectors concurrently. Therefore, the government should consider enacting combined rooftop solar PV + EV decarbonisation policies that offer economic and environmental benefits. • Rooftop solar PV+EV can meet 20%-42% of electricity demand in France's three most populous cities. • Rooftop solar PV+EV can reduce CO 2 emissions from vehicle use and power generation by 43%-48%. • Coupling PV+ EV can be a potentially worthwhile investment with a payback period of 2-3 years, an LCOE of €0.04/kWh, and an NPV of €6-19 billion without a feed-in tariff. • Coupling rooftop solar PV+EV in cities is a cost-effective strategy to decarbonise urban energy, transport and building sectors. • The government should consider enacting PV+EV combined decarbonisation policies that can offer economic and environmental benefits.

Many recent studies on computer-mediated communication (CMC) have addressed the question of orality and literacy. This article examines a relatively recent subgenre of CMC, that of written online sports commentary, that provides us with written CMC that is clearly based on firmly established oral genres, those of radio and television sports commentary. The examples analyzed are from two English, two French, and two Spanish online football (soccer) commentaries. The purpose of the study is to examine oral traits and genre mixing in online football commentaries in the three languages and carryover from the spoken genres of radio and television commentaries to this developing genre, following Ferguson. Special attention is paid to Web page design. The study reveals that form and content of online football commentaries are strongly affected by the style of the online newspaper.

Objectives Combining noninvasive tests increases diagnostic accuracy for staging liver fibrosis in hepatitis C virus ( HCV)-infected patients, but this strategy remains to be validated in HIV/ HCV coinfection. We compared the performances of transient elastography ( TE), Fibrotest ( FT), the aspartate aminotransferase-to-platelet ratio index ( APRI) and two algorithms combining TE and FT ( Castera) or APRI and FT ( SAFE) in HIV/ HCV coinfection. Methods One hundred and sixteen HIV/ HCV-coinfected patients (64% male; median age 44 years) enrolled in two French multicentre studies (the HEPAVIH cohort and FIBROSTIC) for whom TE, FT and APRI data were available were included in the study. Diagnostic accuracies for significant fibrosis ( METAVIR F ≥ 2) and cirrhosis ( F4) were evaluated by measuring the area under the receiver-operating characteristic curve ( AUROC) and calculating percentages of correctly classified ( CC) patients, taking liver biopsy as a reference. Results For F ≥ 2, both TE and FT ( AUROC = 0.87 and 0.85, respectively) had a better diagnostic performance than APRI ( AUROC = 0.71; P < 0.005). Although the percentage of CC patients was significantly higher with Castera's algorithm than with SAFE (61.2% vs. 31.9%, respectively; P < 0.0001), this percentage was lower than that for TE (80.2%; P < 0.0001) or FT (73.3%; P < 0.0001) taken separately. For F4, TE ( AUROC = 0.92) had a better performance than FT ( AUROC = 0.78; P = 0.005) or APRI ( AUROC = 0.73; P = 0.025). Although the percentage of CC patients was significantly higher with the SAFE algorithm than with Castera's (76.7% vs. 68.1%, respectively; P < 0.050), it was still lower than that for TE (85.3%; P < 0.033). Conclusions In HIV/ HCV-coinfected patients, TE and FT have a similar diagnostic accuracy for significant fibrosis, whereas for cirrhosis TE has the best accuracy. The use of the SAFE and Castera algorithms does not seem to improve diagnostic performance. [ABSTRACT FROM AUTHOR]

Introduction: Le diabète appartient à la liste des affections de longue durée (ALD) permettant au malade d’être remboursé à 100 % pour les soins liés au diabète. Bien que l’incidence des ALD pour diabète ne puisse être assimilée à l’incidence réelle du diabète, ses caractéristiques peuvent apporter des informations extrapolables à l’incidence du diabète. Les objectifs de cette étude étaient de décrire l’incidence et les caractéristiques des ALD pour diabète dans les DOM et de les comparer à celles de la France métropolitaine. Matériels et méthodes: Les données sont issues de la Caisse nationale d’Assurance maladie des travailleurs salariés (CnamTS), de la Mutualité sociale agricole (MSA) et du Régime social des indépendants (RSI), qui couvrent 96 % de la population résidant en France. Les taux d’incidence annuels ont été calculés sur la période 2000-2005 et standardisés selon la structure d’âge et de sexe de la population métropolitaine en 2000, Résultats: En 2000-2005, le nombre annuel moyen de personnes admises en ALD pour diabète était de 2 759 à la Réunion, 1 841 en Guadeloupe, 1 292 en Martinique et 275 en Guyane. Sur cette même période, les taux standardisés annuels d’incidence étaient respectivement de 535/100 000, 521/100 000, 371/100 000 et 300/100 000 ; ces taux étaient largement supérieurs à celui de métropole (240/100 000). Dans les DOM, le taux d’incidence était plus élevé chez les femmes que chez les hommes (ratio hommes/femmes entre 0,82 et 0,92), alors qu’il était plus élevé chez les hommes en métropole (ratio = 1,42). À la Réunion, 24 % des admissions concernaient des personnes de moins de 45 ans, 15 % en Guadeloupe, 15 % en Martinique, 23 % en Guyane, versus 11 % en métropole. Ainsi, avant 45 ans, les taux d’incidence atteignaient 270/100 000 à la Réunion, 190/100 000 en Guadeloupe, 147/100 000 en Martinique et 114/100 000 en Guyane, versus 89/100 000 en métropole. L’écart entre les taux d’incidence dans les DOM et en métropole diminuait avec l’âge. Conclusion: Dans les DOM, l’incidence des admissions en ALD pour diabète est 1,2 à 2,3 fois plus élevée qu’en métropole ; elle y est plus précoce et concerne un peu plus les femmes que les hommes, contrairement à la métropole. Ces résultats témoignent du poids important du diabète et de ses spécificités dans les DOM. [Copyright &y& Elsevier]

Older age is associated with increased mortality in immune thrombotic thrombocytopenic purpura (iTTP). Yet, data are scarce regarding iTTP occurring among older patients. To assess clinical features and long-term impact of iTTP on mortality in older patients (>60 years old), characteristics and prognoses of adult iTTP patients enrolled in the French Reference Center for Thrombotic Microangiopathies registry between 2000 and 2016 were described according to age (<60 years old or ≥60 years old). Long-term mortality of iTTP older survivors was compared with that of non-iTTP geriatric subjects. Comparing, respectively, older iTTP patients (N = 71) with younger patients (N = 340), time from hospital admission to diagnosis was longer (P < .0001); at diagnosis, delirium (P = .034), behavior impairment (P = .045), renal involvement (P < .0001), and elevated troponin level (P = .025) were more important whereas cytopenias were less profound (platelet count, 22 × 103/mm3 [9-57] vs 13 × 103/mm3 [9-21], respectively [P = .002]; hemoglobin level, 9 g/dL [8-11] vs 8 g/dL [7-10], respectively [P = .0007]). Short- and mid-term mortalities were higher (P < .0001) and increased for every 10 years of age range. Age ≥60 years, cardiac involvement, increased plasma creatinine level, and total plasma exchange volume were independently associated with 1-month mortality. Compared with a non-iTTP geriatric population, older survivors showed an increased long-term mortality (hazard ratio = 3.44; P < .001). In conclusion, older iTTP patients have atypical neurological presentation delaying the diagnosis. Age negatively impacts short-term but also long-term mortality., (© 2019 by The American Society of Hematology.)

In the absence of perfect reference standard, classical techniques result in biased diagnostic accuracy and prevalence estimates. By statistically defining the true disease status, latent class models (LCM) constitute a promising alternative. However, LCM is a complex method which relies on parametric assumptions, including usually a conditional independence between tests and might suffer from data sparseness. We carefully applied LCMs to assess new campylobacter infection detection tests for which bacteriological culture is an imperfect reference standard. Five diagnostic tests (culture, polymerase chain reaction and three immunoenzymatic tests) of campylobacter infection were collected in 623 patients from Bordeaux and Lyon Hospitals, France. Their diagnostic accuracy were estimated with standard and extended LCMs with a thorough examination of models goodness-of-fit. The model including a residual dependence specific to the immunoenzymatic tests best complied with LCM assumptions. Asymptotic results of goodness-of-fit statistics were substantially impaired by data sparseness and empirical distributions were preferred. Results confirmed moderate sensitivity of the culture and high performances of immunoenzymatic tests. LCMs can be used to estimate diagnostic tests accuracy in the absence of perfect reference standard. However, their implementation and assessment require specific attention due to data sparseness and limitations of existing software.

Background: Acute respiratory failure (ARF) is the leading reason for intensive care unit (ICU) admission in immunocompromised patients. High-flow nasal oxygen (HFNO) therapy is an alternative to standard oxygen. By providing warmed and humidified gas, HFNO allows the delivery of higher flow rates via nasal cannula devices, with FiO 2 values of nearly 100%. Benefits include alleviation of dyspnea and discomfort, decreased respiratory distress and decreased mortality in unselected patients with acute hypoxemic respiratory failure. However, in preliminary reports, HFNO benefits are controversial in immunocompromised patients in whom it has never been properly evaluated., Methods/design: This is a multicenter, open-label, randomized controlled superiority trial in 30 intensive care units, part of the Groupe de Recherche Respiratoire en Réanimation Onco-Hématologique (GRRR-OH). Inclusion criteria will be: (1) adults, (2) known immunosuppression, (3) ARF, (4) oxygen therapy ≥ 6 L/min, (5) written informed consent from patient or proxy. Exclusion criteria will be: (1) imminent death (moribund patient), (2) no informed consent, (3) hypercapnia (PaCO 2 ≥ 50 mmHg), (4) isolated cardiogenic pulmonary edema, (5) pregnancy or breastfeeding, (6) anatomical factors precluding insertion of a nasal cannula, (7) no coverage by the French statutory healthcare insurance system, and (8) post-surgical setting from day 1 to day 6 (patients with ARF occurring after day 6 of surgery can be included). The primary outcome measure is day-28 mortality. Secondary outcomes are intubation rate, comfort, dyspnea, respiratory rate, oxygenation, ICU length of stay, and ICU-acquired infections. Based on an expected 30% mortality rate in the standard oxygen group, and 20% in the HFNO group, error rate set at 5%, and a statistical power at 90%, 389 patients are required in each treatment group (778 patients overall). Recruitment period is estimated at 30 months, with 28 days of additional follow-up for the last included patient., Discussion: The HIGH study will be the largest multicenter, randomized controlled trial seeking to demonstrate that survival benefits from HFNO reported in unselected patients also apply to a large immunocompromised population., Trial Registration: ClinicalTrials.gov, ID: NCT02739451 . Registered on 15 April 2016.

Background: Thrombotic thrombocytopenic purpura is a thrombotic microangiopathy related to a severe deficiency of ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13; activity <10%). We aimed to investigate the association between mechanisms for ADAMTS13 deficiency and the epidemiology and pathophysiology of thrombotic thrombocytopenic purpura at initial presentation., Methods: Between Jan 1, 1999, and Dec 31, 2013, we did a cross-sectional analysis of the French national registry for thrombotic microangiopathy to identify all patients with adult-onset thrombotic microangiopathy (first episode after age 18 years) who had severe ADAMTS13 deficiency at presentation. ADAMTS13 activity, anti-ADAMTS13 IgG, and ADAMTS13 gene mutations were investigated by a central laboratory. We collected patients' clinical data for correlation with their ADAMTS13 phenotype and genotype. We used logistic regression analysis to identify variables significantly associated with idiopathic thrombotic thrombocytopenic purpura, as measured by estimated odds ratios (ORs) and 95% CIs. This study is registered with ClinicalTrials.gov, number NCT00426686., Findings: We enrolled 939 patients with adult-onset thrombotic thrombocytopenic purpura, of whom 772 (82%) patients had available data and samples at presentation and comprised the cohort of interest. The prevalence of thrombotic thrombocytopenic purpura in France was 13 cases per million people. At presentation, 378 (49%) patients had idiopathic thrombotic thrombocytopenic purpura, whereas 394 (51%) patients had disease associated with miscellaneous clinical situations (infections, autoimmunity, pregnancy, cancer, organ transplantation, and drugs). Pathophysiologically, three distinct forms of thrombotic thrombocytopenic purpura were observed: 585 (75%) patients had autoimmune disease with anti-ADAMTS13 IgG, 166 (22%) patients had acquired disease of unknown cause and 21 (3%) patients had inherited disease (Upshaw-Schulman syndrome) with mutations of the ADAMTS13 gene. Idiopathic thrombotic thrombocytopenic purpura were mainly autoimmune (345 [91%] cases), whereas non-idiopathic diseases were heterogeneous, including a high rate of unexplained mechanisms for ADAMTS13 deficiency (133 [34%] cases). Obstetrical thrombotic thrombocytopenic purpura cases (n=62) were specifically remarkable because of the high rate of patients with Upshaw-Schulman syndrome (21 [34%] patients)., Interpretation: Our study shows that thrombotic thrombocytopenic purpura is a heterogeneous syndrome, and that features of the disease at presentation are strongly associated with the mechanisms of ADAMTS13 deficiency. In addition to mechanistic insight, our findings could have implications for the initial therapeutic management of patients with this disorder., Funding: Assistance Publique-Hôpitaux de Paris., (Copyright © 2016 Elsevier Ltd.

Aim: Low survival rate was previously described after cardiac arrest in cancer patients and may challenge the appropriateness of intensive care unit (ICU) admission after return of spontaneous circulation (ROSC). Objectives of this study were to report outcome and characteristics of cancer patients admitted to the ICU after cardiac arrest., Methods: A retrospective chart review in seven medical ICUs in France, in 2002-2012. We studied consecutive patients with malignancies admitted after out-of-hospital cardiac arrest (OHCA) or in-hospital cardiac arrest (IHCA)., Results: Of 133 included patients of whom 61% had solid tumors, 48 (36%) experienced OHCA and 85 (64%) IHCA. Cardiac arrest was related to the malignancy or its treatment in 47% of patients. Therapeutic hypothermia was used in 51 (41%) patients. The ICU mortality rate was 98/133 (74%). Main causes of ICU death were refractory shock or multiple organ failure (n = 64, 48%) and neurological injury (n = 27, 20%); 42 (32%) patients died in ICU after treatment-limitation decisions. Twenty-four (18%) patients were discharged alive from the hospital. Overall 6-month survival rate was 14% (18/133, 95% confidence interval, 8-21%). Survival rates at ICU discharge and after 6 months did not differ significantly across type of malignancy or between the OHCA and IHCA groups, and neither were they significantly different from those in matched controls who had cardiac arrest but no malignancy., Conclusions: Even if low, the 6-month survival rate of 14% observed in cancer patients admitted to the ICU after cardiac arrest and ROSC may support the admission of these patients to the ICU and may warrant an initial full-code ICU management., (Copyright © 2015 Elsevier Ireland Ltd.

Purpose: The prognosis of critically ill cancer patients has improved recently. Controversies remain as regard to the specific prognosis impact of neutropenia in critically ill cancer patients. The primary objective of this study was to assess hospital outcome of critically ill neutropenic cancer patients admitted into the ICU. The secondary objective was to assess risk factors for unfavorable outcome in this population of patients and specific impact of neutropenia., Methods: We performed a post hoc analysis of a prospectively collected database. The study was carried out in 17 university or university-affiliated centers in France and Belgium. Neutropenia was defined as a neutrophil count lower than 500/mm(3)., Results: Among the 1,011 patients admitted into the ICU during the study period 289 were neutropenic at the time of admission. Overall, 131 patients died during their hospital stay (hospital mortality 45.3 %). Four variables were associated with a poor outcome, namely allogeneic transplantation (OR 3.83; 95 % CI 1.75-8.35), need for mechanical ventilation (MV) (OR 6.57; 95 % CI 3.51-12.32), microbiological documentation (OR 2.33; CI 1.27-4.26), and need for renal replacement therapy (OR 2.77; 95 % CI 1.34-5.74). Two variables were associated with hospital survival, namely age younger than 70 (OR 0.22; 95 % CI 0.1-0.52) and neutropenic enterocolitis (OR 0.37; 95 % CI 0.15-0.9). A case-control analysis was also performed with patients of the initial database; after adjustment, neutropenia was not associated with hospital mortality (OR 1.27; 95 % CI 0.86-1.89)., Conclusion: Hospital survival was closely associated with younger age and neutropenic enterocolitis. Conversely, need for conventional MV, for renal replacement therapy, and allogeneic hematopoietic stem cell transplantation (HSCT) were associated with poor outcome.

Background: Cardiac involvement is a major cause of mortality in patients with thrombotic thrombocytopenic purpura (TTP). However, diagnosis remains underestimated and delayed, owing to subclinical injuries. Cardiac troponin-I measurement (cTnI) on admission could improve the early diagnosis of cardiac involvement and have prognostic value., Objectives: To assess the predictive value of cTnI in patients with TTP for death or refractoriness., Patients/methods: The study involved a prospective cohort of adult TTP patients with acquired severe ADAMTS-13 deficiency (< 10%) and included in the registry of the French Reference Center for Thrombotic Microangiopathies. Centralized cTnI measurements were performed on frozen serum on admission., Results: Between January 2003 and December 2011, 133 patients with TTP (mean age, 48 ± 17 years) had available cTnI measurements on admission. Thirty-two patients (24%) had clinical and/or electrocardiogram features. Nineteen (14.3%) had cardiac symptoms, mainly congestive heart failure and myocardial infarction. Electrocardiogram changes, mainly repolarization disorders, were present in 13 cases. An increased cTnI level (> 0.1 μg L(-1) ) was present in 78 patients (59%), of whom 46 (59%) had no clinical cardiac involvement. The main outcomes were death (25%) and refractoriness (17%). Age (P = 0.02) and cTnI level (P = 0.002) showed the greatest impact on survival. A cTnI level of > 0.25 μg L(-1) was the only independent factor in predicting death (odds ratio [OR] 2.87; 95% confidence interval [CI] 1.13-7.22; P = 0.024) and/or refractoriness (OR 3.03; 95% CI 1.27-7.3; P = 0.01)., Conclusions: A CTnI level of > 0.25 μg L(-1) at presentation in patients with TTP appears to be an independent factor associated with a three-fold increase in the risk of death or refractoriness. Therefore, cTnI level should be considered as a prognostic indicator in patients diagnosed with TTP., (© 2014 International Society on Thrombosis and Haemostasis.)

Aims: To assess long-term outcomes and the management of critical left-sided infective endocarditis (IE) and evaluate the impact of surgery., Methods and Results: Among the 198 patients included prospectively for IE across 33 adult intensive care units (ICU) in France from 1 April 2007 to 1 October 2008, 137 (69%) were dead at a median follow-up time of 59.5 months. Characteristics significantly associated with mortality were: Sepsis-related Organ-Failure Assessment (SOFA) score at ICU admission [Hazard ratio (HR), 95% Confidence Interval (CI) of 1.43 (0.79-2.59) for SOFA 5-9; 2.01 (1.05-3.85) for SOFA 10-14; 3.53 (1.75-7.11) for SOFA 15-20; reference category SOFA 0-4; P = 0.003]; prosthetic mechanical valve IE [HR 2.01; 95% CI 1.09-3.69, P = 0.025]; vegetation size ≥15 mm [HR 1.64; 95% CI 1.03-2.63, P = 0.038]; and cardiac surgery [HR (95%CI), 0.33 (0.16-0.67) for surgery ≤1 day after IE diagnosis; 0.61 (0.29-1.26) for surgery 2-7 days after IE diagnosis; 0.42 (0.21-0.83) for surgery >7 days after IE diagnosis; reference category no surgery; P = 0.005]. One hundred and three (52%) patients underwent cardiac surgery after a median time of 6 (16) days. Independent predictors of surgical intervention on multivariate analysis were: age ≤60 years [Odds ratio (OR) 5.30; 95% CI (2.46-11.41), P < 0.01], heart failure [OR 3.27; 95% CI (1.03-10.35), P = 0.04], cardiogenic shock [OR 3.31; 95% CI (1.47-7.46), P = 0.004], septic shock [OR 0.25; 95% CI (0.11-0.59), P = 0.002], immunosuppression [OR 0.15; 95% CI (0.04-0.55), P = 0.004], and diagnosis before or within 24 h of ICU admission [OR 2.81; 95% CI (1.14-6.95), P = 0.025]. SOFA score calculated the day of surgery was the only independently associated factor with long-term mortality [HR (95% CI) 1.59 (0.77-3.28) for SOFA 5-9; 3.56 (1.71-7.38) for SOFA 10-14; 11.58 (4.02-33.35) for SOFA 15-20; reference category SOFA 0-4; P < 0.0001]. Surgical timing was not associated with post-operative outcomes. Of the 158 patients with a theoretical indication for surgery, the 58 deemed not fit had a 95% mortality rate., Conclusion: Mortality in patients with critical IE remains unacceptably high. Factors associated with long-term outcomes are the severity of multiorgan failure, prosthetic mechanical valve IE, vegetation size ≥15 mm, and surgical treatment. Up to one-third of potential candidates do not undergo surgery and these patients experience extremely high mortality rates. The strongest independent predictor of post-operative mortality is the pre-operative multiorgan failure score while surgical timing does not seem to impact on outcomes.

This study reviewed records of all electrical incidents involving work-related injury to employees Electricité de France (EDF) from 1996 through 2005 and analysed data for 311 incidents. The results are compared with 1231 electrical incidents that occurred during 1970-1979 and 996 incidents during 1980-1989. A total of 311 electrical incidents were observed. The medical consequences of electrical incident remain severe and particularly, the current fatality rate (3.2%) is similar to that recorded in the 1980s (2.7%) and 1970s (3.3%). Among individuals with non-fatal incidents, any change has occurred in the prevalence of permanent functional sequelae (23.6% in the 1970s vs. 27.6% in the 1980s and 32.5% currently). An increase in the incidence of neuropsychiatric sequelae (5.4% in the 1980s vs. 13% currently) has been observed and they are now the second most common type of sequelae after those directly related to burns. Among the neurological sequelae, peripheral nervous system disorders are the most common, as observed in the 1980s. Since the definition of post-traumatic stress disorder (PTSD) has changed between the two periods, we can only report that the current prevalence of PTSD is 7.6%. This study emphasises the need for specific management of neurological and psychological impairments after electrical injuries, including especially early recognition and initiation of effective treatment., (Copyright © 2013 Elsevier Ltd and ISBI.

Some patients with drug reaction with eosinophilia and systemic symptoms (DRESS) are probably admitted in intensive care unit (ICU), but data concerning their clinical features at admission are scarce. Therefore, in the present study, we used a clinical network of French intensivists to study the clinical features and evolution of DRESS patients hospitalized in ICU. A national, retrospective, multicenter study collected DRESS cases hospitalized in ICU for DRESS from 2000 to end of 2011. All files were analyzed through the RegiSCAR scoring system as "no," "possible," "probable," or "definite" DRESS. Patients were included only if they had a probable or definite DRESS. Demographic, hemodynamic, biological, and infectious data were recorded. Twenty-one patients were included. Hospital mortality was 10 (47%) of 21, and 16 of 21 patients had on admission a shock state necessitating vasopressor agents. Echocardiographic ejection fraction in shock patients was depressed (47% ± 13%). Mechanical ventilation was required in 13 of 21 cases. Hepatic failure was observed in 11 of 21 cases, acute renal failure in 18 of 20 cases, and lactic acidosis in 12 of 20 patients. Initial bacteriology was negative in all patients. Human herpesvirus reactivations were found in five of 15 cases. In conclusion, shock without bacteriological documentation associated with multiple organ failure is the most common presentation of DRESS at admission in ICU and is associated with a higher mortality than previously described.

PURPOSE Patients with hematologic malignancies are increasingly admitted to the intensive care unit (ICU) when life-threatening events occur. We sought to report outcomes and prognostic factors in these patients. PATIENTS AND METHODS Ours was a prospective, multicenter cohort study of critically ill patients with hematologic malignancies. Health-related quality of life (HRQOL) and disease status were collected after 3 to 6 months. Results Of the 1,011 patients, 38.2% had newly diagnosed malignancies, 23.1% were in remission, and 24.9% had received hematopoietic stem-cell transplantations (HSCT, including 145 allogeneic). ICU admission was mostly required for acute respiratory failure (62.5%) and/or shock (42.3%). On day1, 733 patients (72.5%) received life-supporting interventions. Hospital, day-90, and 1-year survival rates were 60.7%, 52.5%, and 43.3%, respectively. By multivariate analysis, cancer remission and time to ICU admission less than 24 hours were associated with better hospital survival. Poor performance status, Charlson comorbidity index, allogeneic HSCT, organ dysfunction score, cardiac arrest, acute respiratory failure, malignant organ infiltration, and invasive aspergillosis were associated with higher hospital mortality. Mechanical ventilation (47.9% of patients), vasoactive drugs (51.2%), and dialysis (25.9%) were associated with mortality rates of 60.5%, 57.5%, and 59.2%, respectively. On day 90, 80% of survivors had no HRQOL alterations (physical and mental health similar to that of the overall cancer population). After 6 months, 80% of survivors had no change in treatment intensity compared with similar patients not admitted to the ICU, and 80% were in remission. CONCLUSION Critically ill patients with hematologic malignancies have good survival, disease control, and post-ICU HRQOL. Earlier ICU admission is associated with better survival.

Background: The main source of key medical information consists in original articles published in peer-reviewed biomedical journals. Reported studies use increasingly sophisticated statistical and epidemiological approaches that first require a solid understanding of core methods. However, such understanding is not widely shared among physicians. Our aim was to assess whether the basic statistical and epidemiological methods used in original articles published in general biomedical journals are taught during the first years of the medical curriculum in France., Methods: We selected original articles published in The New England Journal of Medicine, The Lancet, and The Journal of the American Medical Association, over a period of six months in 2007 and in 2008. A standardized statistical content checklist was used to extract the necessary information in the "Abstract", "Methods", "Results", footnotes of tables, and legends of figures. The methods used in the selected articles were compared to the national program and the public health program of biostatistics and epidemiology taught during the first six years of medical school., Results: The 237 analyzed original articles all used at least one statistical or epidemiological method. Descriptive statistics, confidence interval and Chi(2) or Fisher tests, methods used in more than 50% of articles, were repeatedly taught throughout the medicine curriculum. Measures of association, sample size, fit and Kaplan-Meier method, used in 40 to 50% of articles, were specifically taught during training sessions on critical reading methods. Cox model (41% of articles) and logistic regression (24% of articles) were never taught. The most widely used illustrations, contingency tables (92%) and flowcharts (48%), were not included in the national program., Conclusion: More teaching of the core methods underlying the understanding of sophisticated methods and illustrations should be included in the early medical curriculum so that physicians can read the scientific literature critically for their medical education., (Copyright © 2013 Elsevier Masson SAS.

Introduction: To provide up-to-date information on the prognostic factors associated with 28-day mortality in a cohort of septic shock patients in intensive care units (ICUs)., Methods: Prospective, multicenter, observational cohort study in ICUs from 14 French general (non-academic) and university teaching hospitals. All consecutive patients with septic shock admitted between November 2009 and March 2011 were eligible for inclusion. We prospectively recorded data regarding patient characteristics, infection, severity of illness, life support therapy, and discharge., Results: Among 10,941 patients admitted to participating ICUs between October 2009 and September 2011, 1,495 (13.7%) patients presented inclusion criteria for septic shock and were included. Invasive mechanical ventilation was needed in 83.9% (n=1248), inotropes in 27.7% (n=412), continuous renal replacement therapy in 32.5% (n=484), and hemodialysis in 19.6% (n=291). Mortality at 28 days was 42% (n=625). Variables associated with time to mortality, right-censored at day 28: age (for each additional 10 years) (hazard ratio (HR)=1.29; 95% confidence interval (CI): 1.20-1.38), immunosuppression (HR=1.63; 95%CI: 1.37-1.96), Knaus class C/D score versus class A/B score (HR=1.36; 95%CI:1.14-1.62) and Sepsis-related Organ Failure Assessment (SOFA) score (HR=1.24 for each additional point; 95%CI: 1.21-1.27). Patients with septic shock and renal/urinary tract infection had a significantly longer time to mortality (HR=0.56; 95%CI: 0.42-0.75)., Conclusion: Our observational data of consecutive patients from real-life practice confirm that septic shock is common and carries high mortality in general ICU populations. Our results are in contrast with the clinical trial setting, and could be useful for healthcare planning and clinical study design.

Purpose: Although plasma therapy of thrombotic micro-angiopathies (TMAs) has dramatically improved survival, the outcome remains fatal in up to 15 % of patients. We investigated the causes and risk factors of death in patients with TMA., Methods: Retrospective matched case-control national-registry study of 57 patients who died within 180 days of TMA diagnosis and 48 survivors matched on age, gender, and baseline platelet count and creatinine level. The study period was 1995-2007. Factors associated with mortality were identified using a conditional logistic regression model., Results: Median time from TMA symptom onset to death was 7 (5-14) days. The leading causes of death were nosocomial infections, myocardial infarction, stroke, and pulmonary embolism. Cases and controls did not differ significantly regarding haemolysis parameters, ADAMTS13 activity, or neurological or gastrointestinal involvement. TMA was more frequently related to HIV or cancer in patients who died. Compared to survivors, non-survivors more often had cardiac involvement at diagnosis (38 vs. 6 %, p = 0.03) and less often received plasma exchange therapy (60 vs. 92 %, p = 0.004). Only two factors were independently associated with mortality by multivariate analysis: cardiac involvement at diagnosis (odds ratio, 5.96; 95 % confidence interval, 1.06-33.4) and plasma exchange therapy (odds ratio, 0.25; 95 % confidence interval, 0.06-0.99)., Conclusion: Our data emphasise the adverse prognostic significance of cardiac abnormalities and support routine plasma exchange in patients with TMA. Given the high risk of cardiac and neurological complications, adequate monitoring should be proposed to these patients in appropriate hospital settings.

Background & Aims: The diagnostic accuracy of non-invasive liver fibrosis tests that may replace liver biopsy in patients with chronic hepatitis remains controversial. We assessed and compared the accuracy of FibroScan® and that of the main biomarkers used for predicting cirrhosis and significant fibrosis (METAVIR ≥ F2) in patients with chronic viral hepatitis., Methods: A multicenter prospective cross-sectional diagnostic accuracy study was conducted in the Hepatology departments of 23 French university hospitals. Index tests and reference standard (METAVIR fibrosis score on liver biopsy) were measured on the same day and interpreted blindly. Consecutive patients with chronic viral hepatitis (hepatitis B or C virus, including possible Human Immunodeficiency Virus co-infection) requiring liver biopsy were recruited in the study., Results: The analysis was first conducted on the total population (1839 patients), and after excluding 532 protocol deviations, on 1307 patients (non-compliant FibroScan® examinations). The overall accuracy of FibroScan® was high (AUROC 0.89 and 0.90, respectively) and significantly higher than that of biomarkers in predicting cirrhosis (AUROC 0.77-0.86). All non-invasive methods had a moderate accuracy in predicting significant fibrosis (AUROC 0.72-0.78). Based on multilevel likelihood ratios, non-invasive tests provided a relevant gain in the likelihood of diagnosis in 0-60% of patients (cirrhosis) and 9-30% of patients (significant fibrosis)., Conclusions: The diagnostic accuracy of non-invasive tests was high for cirrhosis, but poor for significant fibrosis. A clinically relevant gain in the likelihood of diagnosis was achieved in a low proportion of patients. Although the diagnosis of cirrhosis may rely on non-invasive tests, liver biopsy is warranted to diagnose intermediate stages of fibrosis., (Copyright © 2010 European Association for the Study of the Liver.

This study presents the pattern of exposure to uranium and other occupational pollutants known to be potentially carcinogenic, mutagenic or toxic and used at the main uranium conversion plant in France. For different uranium compounds specified according to their solubility and purity, and 16 other categories of pollutants: chemicals, fibres, vapours, dust, and heat a time- and plant-specific job exposure matrix (JEM) was created covering the period 1960-2006. For 73 jobs and for each pollutant the amount and frequency of exposure were assessed on a four-level scale by different time periods. The JEM shows 73% sensitivity and 83% specificity. Although exposure assessment was semi-quantitative, the JEM allows computing of individual cumulative exposure score for each pollutant across time. Despite the predominant natural uranium compounds exposure, the amount of exposure to other pollutants such as TCE and other chlorinated products, asbestos, and fibres, is important at the plant. Numerous correlations detected between uranium compounds exposure and exposure to chemicals warrants improving biological monitoring of exposed workers and accounting for associated exposures in epidemiological studies. Results of this study will be used for further investigation of association between exposure and mortality among uranium conversion workers cohort.

Background: A pilot study was carried out in the AREVA NC Pierrelatte nuclear facility in order to investigate a possible carcinogenic effect of internal radiation exposure among nuclear workers in France. The objective of this study was to develop a method for retrospective reconstruction of the occupational exposure to internal radiation from uranium and associated chemical exposures., Methods: A plant- and period-specific job exposure matrix (JEM) was designed. Job groups and exposure agents groups including uranium compounds and other chemical agents known as being carcinogenic, mutagenic or toxic were defined by an expert committee. Exposure was evaluated by active and retired workers included in the evaluator committee. A quantitative assignment of quantity and frequency of handling (both coded from 0 to 3) was performed for each agent groups using a method derived from the Delphi technique., Results: In all, 23 experts and 353 evaluators participated to the JEM elaboration. A final JEM involved 232 "job-periods" presenting throughout the plant period 1960-2006 and 22 exposure agents groups in use at the plant. Six of them involved uranium compounds classified by their blood-transferability and toxicity characteristics. A first validation of the JEM by experts in radiological protection and industrial hygiene showed an acceptable internal consistency., Conclusion: In the context of missing past exposure measurement data, the plant- and period-specific job exposure matrices may be considered as a valid alternative for exposure estimation. This method may be applied to other nuclear plants and offers allowance to investigate a possible carcinogenic effect of internal radiation exposure among nuclear workers.

Background: The residual risk of human immunodeficiency virus (HIV) infection from screened blood transfusion was estimated to be 1.7/10(6) between 1993 and 1995 in France. To orient blood safety policies, we have evaluated what would be, from the perspective of blood banks, the best screening strategy in terms of gain in effectiveness and added costs., Methods: A cost-effectiveness analysis compared 20 HIV-testing protocols using (1) available data for performances of the current screening tests; and, (2) national insurance estimates for the cost of tests. Results were expressed as the number of false negative donations that would be avoided and the cost by avoided false negative donation., Results: For 3 million donated blood units a year and a prevalence of 24 per million, there would be 72 infectious donated blood units, 70.56 of which would be detected by the current screening strategy. The number of additional donated blood infections avoided in all other strategies would be low (between 0.25 and 1.28) with a very high cost (280 million French francs per added false negative avoided or more)., Conclusion: A change in screening strategies for blood donations in France is not currently justified. If such a change was to be done, adding p24 antigen detection to the current screening strategy would be one of the worst solutions.

At the request of the regional authority, the system of traceability of blood products in the Midi-Pyrenees area in France was assessed using available documentation, visits and interviews of participants. We studied the time needed to obtain traceability data in the Blood Banks and the reactivity of the system defined as the time needed to carry out a simulated descending transfusional survey. This information allowed us to assess usefulness and cost of the system, its applicability and the timeliness of information, according to the criteria of the Centers for Disease Control. The system is based on a standardized nominative form for the delivery of blood products and specific feedback. For the participants, traceability makes transfusional surveys easier and improves transfusions safety. In two of the 130 hospitals, the system is linked to the "program of medicalization of information systems". In the 2nd semester of 1996, the traceability proportion was 97%. For a given date of distribution, 75% of blood products were traced in 14 days and 83% in a month. The study of reactivity showed that all donations coming from two randomly chosen blood collection sites could be traced in about 2 hours. This first evaluation of a regional system of traceability showed its feasibility and acceptability, based on evaluation criteria of a public health surveillance system. A continuous evaluation process would be necessary to assess the good functioning of the system and to detect and prevent possible deficiencies.

The aim of this pilot study was to assess the feasibility of a tolerance study of qualified (secured by quarantine or solvent-detergent-treated) fresh frozen plasma (FFP) in real conditions of use. We included all patients receiving qualified FFP during a one-month observation period in three french hospitals (Besançon, Brest, Lyon). The 192 FFP transfusion episodes corresponded to 111 patients. Only two thirds of all prescriptions corresponded to indications mentioned in the ministerial order of december 1991. Forty-two episodes consisted of FFP only; in the 150 remaining episodes, at least one product (mostly labile blood products) had been injected within 24 hours before or after the plasma injection. The free interval between FFP transfusion and the nearest associated product was usually less than three hours. Only one side effect was notified. This pilot study points out the difficulties of a tolerance study of qualified FFP in real conditions of use. It also raises the necessity to clarify current indications of FFP.

Unlabelled: An epidemiologic study of patients consulting General Practitioners (GPs) was conducted among GPs who usually collaborate on Aquitaine Sentinel Network, supported by the Department of Medical Informatics of the University of Bordeaux II. One day in June and one day in December 1992, each GP who participated in this investigation had to collect age, sex and reason for consulting about every patient who took medical advice. For every patient over 15 year old, on the day of the consultation or the previous week, the GP had to collect signs of depression, dysphoria, loss of interest or pleasure in the daily-living activities, insomnia, fatigue, inappropriate guilt, diminished ability to think or indecisiveness, recurrent thoughts of death..., Results: In June, 79 GPs collected data on 1,500 patients and in December 80 GPs interviewed 1,400 patients. The main sign was fatigue (35%). Then, in frequency order, sleep disorders (26.5%), appetite and weight disorders (22.7%), dysphoria (18.7%) and loss of interest or pleasure for daily-living activities (16.7%) have been found. Among patients who present at least one of the signs of depression (more than 50% of the sample), half had associated handicap in every-day life activities. Major depression prevalence rate was respectively 5% in June and 6.3% in December whereas dysthymia was 4.3%.
