Treatment of carbapenemase‐producing Enterobacterales bloodstream infections in solid organ transplant recipients is challenging. The objective of this study was to develop a specific score to predict mortality in solid organ transplant recipients with carbapenemase‐producing Enterobacterales bloodstream infections. A multinational, retrospective (2004‐2016) cohort study (INCREMENT‐SOT, ClinicalTrials.gov NCT02852902) was performed. The main outcome variable was 30‐day all‐cause mortality. The INCREMENT‐SOT‐CPE score was developed using logistic regression. The global cohort included 216 patients. The final logistic regression model included the following variables: INCREMENT‐CPE mortality score ≥8 (8 points), no source control (3 points), inappropriate empirical therapy (2 points), cytomegalovirus disease (7 points), lymphopenia (4 points), and the interaction between INCREMENT‐CPE score ≥8 and CMV disease (minus 7 points). This score showed an area under the receiver operating characteristic curve of 0.82 (95% confidence interval [CI] 0.76‐0.88) and classified patients into 3 strata: 0‐7 (low mortality), 8‐11 (high mortality), and 12‐17 (very‐high mortality). We performed a stratified analysis of the effect of monotherapy vs combination therapy among 165 patients who received appropriate therapy. Monotherapy was associated with higher mortality only in the very‐high (adjusted hazard ratio [HR] 2.82, 95% CI 1.13‐7.06, P = .03) and high (HR 9.93, 95% CI 2.08‐47.40, P = .004) mortality risk strata.

Objective: To identify the prevalence of musculoskeletal disorders in adolescents, and to analyze this prevalence relationship with sociodemographic, anthropometric and contextual variables. Methods: An observational, cross-sectional, descriptive/relational study with quantitative approach was conceptualized, involving 632 adolescents with mean age of 13.36 from six school groups from Central and North Portugal. Data collection protocol included questions of sociodemographic, anthropometric and contextual nature, and also the “Nordic Musculoskeletal Questionnaire” to assess musculoskeletal disorders. Results: Data showed that 47.4% of adolescents mentioned musculoskeletal disorders within the last 3 months, located in the shoulders (27.8%), dorsal region (25.3%), thigh/hips (26.1%), neck (23.4%), lumbar region (22.8%), and knees (19.6%). We found that musculoskeletal disorders are more prevalent in female adolescents, and among those who spend longer time watching television per day, and also those who go to school by foot or bicycle. Conclusion: The prevalence of musculoskeletal disorders in adolescents is high and has multicausal origin, turning imperative the implementation of preventive and readapted actions to promote a better musculoskeletal function. Objetivo: Identifi car a prevalência das perturbações músculo-esqueléticas em adolescentes e analisar a sua relação com variáveis sociodemográfi cas, antropométricas e contextuais. Métodos: Conceptualizou-se um estudo observacional, transversal, descritivo/relacional de cariz quantitativo, que envolveu 632 adolescentes de seis agrupamentos de escolas das zonas centro e norte de Portugal, com média de idades de 13,36 anos. O protocolo de colheita de dados integrava questões de cariz sociodemográfi co, antropométrico, contextual e ainda o “Questionário Nórdico Músculo-Esquelético” para avaliar as perturbações músculo-esqueléticas. Resultados: Os dados mostraram que 47,4% dos adolescentes referem perturbação músculo-esqueléticas nos últimos 3 meses, localizando-se estas aos níveis dos ombros (27,8%), região dorsal (25,3%), coxa/anca (26,1%), pescoço (23,4%), zona lombar (22,8%) e joelhos (19,6%). Verifi cou-se ainda, que as perturbações músculo-esqueléticas são mais prevalentes nos adolescentes do género feminino, naqueles que gastam mais tempo por dia a ver televisão e ainda nos que se deslocam para a escola a pé ou de bicicleta. Conclusão: A prevalência das perturbações músculo-esqueléticas nos adolescentes é elevada, tem origem multicausal, tornando-se imperativa a implementação de intervenções de prevenção e readaptação promotoras de um funcionamento músculo-esquelético otimizado. info:eu-repo/semantics/publishedVersion

Background Monitoring seasonal influenza epidemics is the corner stone to epidemiological surveillance of acute respiratory virus infections worldwide. This work aims to compare two sentinel surveillance systems within the Daily Acute Respiratory Infection Information System of Catalonia (PIDIRAC), the primary care ILI and Influenza confirmed samples from primary care (PIDIRAC-ILI and PIDIRAC-FLU) and the severe hospitalized laboratory confirmed influenza system (SHLCI), in regard to how they behave in the forecasting of epidemic onset and severity allowing for healthcare preparedness. Methods Epidemiological study carried out during seven influenza seasons (2010-2017) in Catalonia, with data from influenza sentinel surveillance of primary care physicians reporting ILI along with laboratory confirmation of influenza from systematic sampling of ILI cases and 12 hospitals that provided data on severe hospitalized cases with laboratory-confirmed influenza (SHLCI-FLU). Epidemic thresholds for ILI and SHLCI-FLU (overall) as well as influenza A (SHLCI-FLUA) and influenza B (SHLCI-FLUB) incidence rates were assessed by the Moving Epidemics Method. Results Epidemic thresholds for primary care sentinel surveillance influenza-like illness (PIDIRAC-ILI) incidence rates ranged from 83.65 to 503.92 per 100.000 h. Paired incidence rate curves for SHLCI -FLU / PIDIRAC-ILI and SHLCI-FLUA/ PIDIRAC-FLUA showed best correlation index' (0.805 and 0.724 respectively). Assessing delay in reaching epidemic level, PIDIRAC-ILI source forecasts an average of 1.6 weeks before the rest of sources paired. Differences are higher when SHLCI cases are paired to PIDIRAC-ILI and PIDIRAC-FLUB although statistical significance was observed only for SHLCI-FLU/PIDIRAC-ILI (p-value Wilcoxon test = 0.039). Conclusions The combined ILI and confirmed influenza from primary care along with the severe hospitalized laboratory confirmed influenza data from PIDIRAC sentinel surveillance system provides timely and accurate syndromic and virological surveillance of influenza from the community level to hospitalization of severe cases.

Gut microbiota contributes to non-alcoholic fatty liver disease (NAFLD) pathogenesis by multiple mechanisms not yet completely understood. Novel differential features between germ-free mice (GFm) transplanted with protective or non-protective cecal microbiota against NAFLD are investigated.

Scope Modulation of intestinal microbiota has emerged as a new therapeutic approach for non-alcoholic fatty liver disease (NAFLD). Herein, it is addressed whether gut microbiota modulation by quercetin and intestinal microbiota transplantation can influence NAFLD development. Methods and results Gut microbiota donor mice are selected according to their response to high-fat diet (HFD) and quercetin in terms of obesity and NAFLD-related biomarkers. Germ-free recipients displayed metabolic phenotypic differences derived from interactions between microbiota transplanted, diets, and quercetin. Based on the evaluation of hallmark characteristics of NAFLD, it is found that gut microbiota transplantation from the HFD-non-responder donor and the HFD-fed donor with the highest response to quercetin results in a protective phenotype against HFD-induced NAFLD, in a mechanism that involves gut-liver axis alteration blockage in these receivers. Gut microbiota from the HFD-responder donor predisposed transplanted germ-free mice to NAFLD. Divergent protective and deleterious metabolic phenotypes exhibited are related to definite microbial profiles in recipients, highlighting the predominant role of Akkermansia genus in the protection from obesity-associated NAFLD development. Conclusions The results provide scientific support for the prebiotic capacity of quercetin and the transfer of established metabolic profiles through gut microbiota transplantation as a protective strategy against the development of obesity-related NAFLD.

International audience; Background: Scedosporium species and Lomentospora prolificans (S/L) are the second most common causes of invasive mold infections following Aspergillus in lung transplant recipients.Methods: We assessed the current practices on management of S/L colonization/infection of the lower respiratory tract before and after lung transplantation in a large number of lung transplant centers through an international practice survey from October 2016 to March 2017.Results: A total of 51 respondents from 45 lung transplant centers (17 countries, 4 continents) answered the survey (response rate 58%). S/L colonization was estimated to be detected in candidates by 48% of centers. Only 18% of the centers used a specific medium to detect S/L colonization. Scedosporium spp. colonization was a contraindication to transplantation in 10% of centers whereas L prolificans was a contraindication in 31%; 22% of centers declared having had 1-5 recipients infected with S/L in the past 5 years.Conclusions: This survey gives an overview of the current practices regarding S/L colonization and infection in lung transplant centers worldwide and underscores the need of S/L culture procedure standardization before implementing prospective studies.
