Blood Parameters in Children and Adolescents With Underweight and Atypical Anorexia Nervosa.

OBJECTIVE: This study aimed to identify biochemical, hematological, and endocrinological abnormalities in a sample of children and adolescents with underweight AN and atypical AN and to compare these results between the two groups. METHOD: Based on the 5th BMI-percentile admission, adolescents with underweight AN (n = 520) and atypical AN (n = 255) were included and medical records were reviewed. RESULTS: Low prealbumin (35%) and neutropenia (39%), and several abnormalities in endocrinological parameters (50%) were the most common alterations found in the whole sample. Compared to the atypical AN group, the underweight AN group had significantly higher frequencies of elevated cholesterol (OR = 2.50; p < 0.001) and alanine aminotransferase (OR = 0.22; p = 0.005) and of reduced insulin-like growth (IGF) factor-1 (OR = 0.29; p < 0.001), T3 (OR = 0.46; p < 0.001), luteinizing hormone (OR = 0.24; p < 0.001), follicle stimulating hormone (OR = 0.58; p = 0.004), and 17b-estradiol (OR = 0.39; p < 0.001). However, other blood parameters showed similar alterations in both groups. DISCUSSION: Both groups showed abnormalities in the same blood parameters, but some abnormal parameters were more common in the underweight AN group. These results suggest that atypical AN and underweight AN could present similar risks of certain medical complications.

Long-term cardiac assessment in a sample of adolescent-onset anorexia nervosa.

BACKGROUND: High mortality rates have been reported in patients with anorexia nervosa, mainly due to cardiovascular alterations. The purpose of the present study was to assess cardiac structural and functional abnormalities some 20 years after initial treatment in a sample of adolescent-onset anorexia nervosa (A-AN) and to compare them with matched healthy controls (HC). METHODS: A sample of 29 women diagnosed and treated for AN during adolescence (A-AN) were assessed more than 20 years later. A complete cardiac evaluation was carried out including an electrocardiogram (ECG) and a standard 2D echocardiography. Thirty matched HC were also assessed. RESULTS: In the A-AN group, four subjects had a body mass index lower than 18.5 and met full DSM 5 criteria for AN at follow-up (Low-Weight group). They were compared with the rest of the sample (n = 25) who had normalized their weight (Normal-Weight group), though some still showed some eating disorder symptoms. Both groups were compared with the HC group. Subjects in the Low-Weight group presented statistically significant decreases in the left ventricular end-diastolic and left atrium dimensions and left ventricular mass in comparison with the Normal-Weight group and the HC. No other differences in cardiac parameters were found between groups. CONCLUSIONS: Echocardiographic and ECG parameters of adults who had presented A-AN twenty years earlier and currently maintained normal weight were similar to those of HC who had never been treated or diagnosed with AN. Adult subjects with A-AN who still had low weight in the long term present certain cardiac abnormalities similar to those seen in short-lasting disease. More studies are needed to confirm these results in a larger sample.

Anorexia nervosa is associated with multiple medical complications and high mortality, mainly due to cardiovascular complications. The main objective of the project was to study long-term cardiac abnormalities in a group of patients diagnosed with anorexia nervosa during adolescence. A sample of 29 patients, treated during adolescence for anorexia nervosa, were evaluated 20 years later. We did an echocardiogram and an electrocardiogram to all of them, and compared them with 30 healthy controls. Of the 29 patients with anorexia nervosa, 4 had low weight and 25 had normal weight. Patients who had normalized their weight did not present cardiac alterations and did not differ from the healthy controls. The 4 underweight patients did present cardiac abnormalities similar to those observed in short-term studies, such as decreased dimensions and mass of the left ventricle and the left atrium.

Impact of switching to raltegravir and/or adding losartan in lymphoid tissue fibrosis and inflammation in people living with HIV. A randomized clinical trial.

BACKGROUND: Persistent inflammation and immune activation are associated with lymph node fibrosis and end-organ diseases in treatment-suppressed people living with HIV (PLWH). We investigated the effect of switching to raltegravir and/or adding losartan on lymphoid tissue fibrosis and on the inflammatory/immune-activation mediators in treated HIV patients. METHODS: Chronic HIV-infected patients treated with two nucleoside reverse transcriptase inhibitors (2NRTI) and one non-NRTI (NNRTI) or protease inhibitor (PI) during at least 48 weeks were randomized to four groups (n = 48): 2NRTI + efavirenz (EFV), 2NRTI + EFV + losartan, 2NRTI + raltegravir and 2NRTI + raltegravir + losartan for 48 weeks. Tonsillar biopsy and peripheral blood markers of CD4 and CD8 T-lymphocyte activation and senescence, monocyte activation and soluble markers of inflammation were determined at baseline and at week 48 and compared between groups. RESULTS: No changes in lymphoid tissue architecture were observed. Adding losartan had no impact on lymphocyte subsets. Conversely, patients who switched to raltegravir showed a higher decrease in all activated [CD4+CD38+HLA-DR+, -0.3 vs. 0.48 (P = 0.033); CD8+CD38+ HLA-DR+, -1.6 vs. 1.3 (P = 0.02)] and senescent [CD4+CD28-CD57+, -0.3 vs. 0.26 (P = 0.04); CD8+CD28-CD57+, -6.1 vs. 3.8 (P = 0.002)] T lymphocytes. In addition, the median CD4/CD8 ratio increased by 0.35 in patients in the raltegravir group vs. 0.03 in the other arms (P = 0.002). Differences between groups in monocyte subpopulations or soluble inflammation markers were not observed. CONCLUSIONS: Losartan had no effect on lymphoid fibrosis or immune activation/inflammation. Conversely, switching to a regimen with raltegravir significantly decreased activated and senescent T-lymphocyte subpopulations and increased CD4/CD8 ratio in successfully treated PLWH.

Recommendations for the treatment of anti-melanoma differentiation-associated gene 5-positive dermatomyositis-associated rapidly progressive interstitial lung disease.

OBJECTIVES: The study aimed to develop evidence-based recommendations for the treatment of rapidly progressive interstitial lung disease (RPILD) associated with the anti-Melanoma Differentiation-Associated Gene 5-positive dermatomyositis (DM) syndrome. METHODS: The task force comprised an expert panel of specialists in rheumatology, intensive care medicine, pulmonology, immunology, and internal medicine. The study was carried out in two phases: identifying key areas in the management of DM-RPILD syndrome and developing a set of recommendations based on a review of the available scientific evidence. Four specific questions focused on different treatment options were identified. Relevant publications in English, Spanish or French up to April 2018 were searched systematically for each topic using PubMed (MEDLINE), EMBASE, and Cochrane Library (Wiley Online). The experts used evidence obtained from these studies to develop recommendations. RESULTS: A total of 134 studies met eligibility criteria and formed the evidentiary basis for the recommendations regarding immunosuppressive therapy and complementary treatments. Overall, there was general agreement on the initial use of combined immunosuppressive therapy. Combination of high-dose glucocorticoids and calcineurin antagonists with or without cyclophosphamide is the first choice. In the case of calcineurin antagonist contraindication or treatment failure, switching or adding other immunosuppressants may be individualized. Plasmapheresis, polymyxin B hemoperfusion and/or intravenous immunoglobulins may be used as rescue options. ECMO should be considered in life-threatening situations while waiting for a clinical response or as a bridge to lung transplant. CONCLUSIONS: Thirteen recommendations regarding the treatment of the anti-MDA5 positive DM-RPILD were developed using research-based evidence and expert opinion.

Screening for trisomies by cfDNA testing of maternal blood in twin pregnancy: update of The Fetal Medicine Foundation results and meta-analysis.

OBJECTIVES: To report on the routine clinical implementation of cell-free DNA (cfDNA) analysis of maternal blood for trisomies 21, 18 and 13 in twin pregnancy and to define the performance of the test by combining our results with those identified in a systematic review of the literature. METHODS: The data for the prospective study were derived from screening for trisomies 21, 18 and 13 in twin pregnancies at 10 + 0 to 14 + 1 weeks' gestation. Two populations were included; first, self-referred women to the Fetal Medicine Centre in London or Brugmann University Hospital in Brussels and, second, women selected for the cfDNA test after routine first-trimester combined testing at one of two National Health Service hospitals in England. This dataset was used to determine the performance of screening for the three trisomies. Search of MEDLINE, EMBASE, CENTRAL (The Cochrane Library), ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform (ICTRP) was carried out to identify all peer-reviewed publications on clinical validation or implementation of maternal cfDNA testing for trisomies 21, 18 and 13 in twin pregnancy. A meta-analysis was then performed using our data and those in the studies identified by the literature search. RESULTS: In our dataset of 997 twin pregnancies with a cfDNA result and known outcome, the test classified correctly 16 (94.1%) of the 17 cases of trisomy 21, nine (90.0%) of the 10 cases of trisomy 18, one (50.0%) of the two cases of trisomy 13 and 962 (99.4%) of the 968 cases without any of the three trisomies. The literature search identified seven relevant studies, excluding our previous papers because their data are included in the current study. In the combined populations of our study and the seven studies identified by the literature search, there were 56 trisomy-21 and 3718 non-trisomy-21 twin pregnancies; the pooled weighted detection rate (DR) and false-positive rate (FPR) were 98.2% (95% CI, 83.2-99.8%) and 0.05% (95% CI, 0.01-0.26%), respectively. In the combined total of 18 cases of trisomy 18 and 3143 non-trisomy-18 pregnancies, the pooled weighted DR and FPR were 88.9% (95% CI, 64.8-97.2%) and 0.03% (95% CI, 0.00-0.33%), respectively. For trisomy 13, there were only three affected cases and two (66.7%) of these were detected by the cfDNA test at a FPR of 0.19% (5/2569). CONCLUSIONS: The performance of cfDNA testing for trisomy 21 in twin pregnancy is similar to that reported in singleton pregnancy and is superior to that of the first-trimester combined test or second-trimester biochemical testing. The number of cases of trisomies 18 and 13 is too small for accurate assessment of the predictive performance of the cfDNA test. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Detección de trisomías mediante la prueba del ADN fetal de la sangre materna en el embarazo de gemelos: actualización de los resultados de The Fetal Medicine Foundation y metaanálisis OBJETIVOS: Informar sobre la implementación clínica rutinaria del análisis de ADN fetal (cfDNA, por sus siglas en inglés) de la sangre materna para las trisomías 21, 18 y 13 en embarazos de gemelos y definir el rendimiento de la prueba mediante la combinación de los resultados de este estudio con los identificados en una revisión sistemática de la literatura. MÉTODOS: Los datos para el estudio prospectivo se derivaron del cribado de las trisomías 21, 18 y 13 en embarazos de gemelos entre 10+0 a 14+1 semanas de gestación. Se incluyeron dos poblaciones: la primera, las mujeres que acudieron sin recomendación de especialista al Centro de Medicina Fetal de Londres o al Hospital Universitario Brugmann de Bruselas y, la segunda, las mujeres seleccionadas para la prueba de cfDNA después de la prueba combinada rutinaria del primer trimestre en uno de los dos hospitales del Servicio Nacional de Salud de Inglaterra. Este conjunto de datos se utilizó para determinar el rendimiento de la detección de las tres trisomías. Se realizó una búsqueda en MEDLINE, EMBASE, CENTRAL (The Cochrane Library), ClinicalTrials.gov y en la Plataforma Internacional del Registro de Ensayos Clínicos (ICTRP, por sus siglas en inglés) de la Organización Mundial de la Salud para identificar todas las publicaciones revisadas por pares sobre la validación clínica o la implementación de pruebas de cfDNA materno para las trisomías 21, 18 y 13 en el embarazo de gemelos. A continuación, se realizó un metaanálisis de los datos propios y de los de los estudios identificados por la búsqueda bibliográfica. RESULTADOS: En el conjunto de datos propios de 997 embarazos de gemelos con un resultado de cfDNA conocido, la prueba clasificó correctamente 16 (94,1%) de los 17 casos de trisomía 21, nueve (90,0%) de los 10 casos de trisomía 18, uno (50,0%) de los dos casos de trisomía 13 y 962 (99,4%) de los 968 casos sin ninguna de las tres trisomías. La búsqueda bibliográfica identificó siete estudios relevantes, que excluyeron los artículos de los autores de este estudio ya que sus datos están incluidos en este estudio. En las poblaciones combinadas de este estudio y los siete estudios identificados por la búsqueda bibliográfica, hubo 56 embarazos gemelares con trisomía-21 y 3718 sin trisomía-21; la tasa de detección (TD) combinada ponderada y la tasa de falsos positivos (TFP) fueron del 98,2% (IC 95%: 83,2-99,8%) y del 0,05% (IC 95%: 0,01-0,26%), respectivamente. En el total combinado de los 18 casos de trisomía-18 y los 3143 embarazos sin trisomía-18, la TD combinada ponderada y la TFP fueron del 88,9% (IC 95%, 64,8-97,2%) y del 0,03% (IC 95%, 0,00-0,33%), respectivamente. Para la trisomía 13, sólo hubo tres casos afectados y dos (66,7%) de ellos fueron detectados por la prueba de cfDNA con una TFP del 0,19% (5/2569). CONCLUSIONES: La bondad del desempeño de la prueba de cfDNA para la trisomía 21 en el embarazo de gemelos es similar a la reportada en embarazos con feto único y es superior a la de la prueba combinada del primer trimestre o a la de la prueba bioquímica del segundo trimestre. El número de casos de trisomías 18 y 13 es demasiado pequeño para una evaluación precisa de la bondad de predicción de la prueba de cfDNA.

Conocimiento y habilidades de enfermeras y médicos en ventilación mecánica no invasiva: equipamiento e influencias contextuales / Nurses' and physicians' knowledge and skills in non-invasive ventilation: Equipment and contextual influences

Objetivos: Evaluar el conocimiento y habilidades de enfermeras y médicos en ventilación mecánica no invasiva en diferentes contextos: equipamiento e influencias contextuales. Método: Estudio descriptivo transversal en 4 unidades de cuidados intensivos (una quirúrgica, 3 polivalentes), una reanimación posquirúrgica, 2 áreas de urgencias y 3 salas de hospitalización, de 4 hospitales (3 universitarios y uno general) con 407 profesionales. Se administró una encuesta con 13 ítems, evaluando la validez del contenido (índice de Kappa 0,97 [95% IC: 0,965-0,975]). Resultados: Respondieron el 63,7% de las enfermeras y el 39% de los médicos. El porcentaje de respuestas correctas fue del 50%. Con una puntuación del 1 al 5, en la que a menor puntuación más conocimiento, las enfermeras puntuaron 3,27 ± 0,5 vs. 2,62 ± 0,5 los médicos (diferencia de la media 0,65 [IC 95%: 0,48-0,82; p < 0,001]). No hubo diferencias entre hospitales o unidades (p = 0,07 y p = 0,09). Un porcentaje notable de profesionales identificó como estrategia para mejorar la sincronización paciente-ventilador «tapar el puerto espiratorio» (fugas intencionadas) y apretar la máscara a la cara del paciente (fugas no intencionadas) (28,2% unidad de cuidados intensivos, 22,5% urgencias, 8,3% reanimación posquirúrgica, 61,5% hospitalización), sin diferencia entre enfermeras y médicos (27,9% vs. 23,4%, p = 0,6). El 50% de las enfermeras respondieron correctamente cómo seleccionar el tamaño adecuado de máscara y el 11,7% conocía que la máscara debe ajustarse permitiendo el paso de 2 dedos. Conclusiones: No hubo diferencias en el conocimiento por unidades entre enfermeras y médicos. La falta de conocimiento relacionada con la terapia de la ventilación mecánica no invasiva es dependiente de la formación recibida y del material disponible en la unidad. Para reducir la confusión entre fugas intencionadas y no intencionadas se recomienda usar un solo tipo de ventilador y mantener un entrenamiento regular de las enfermeras

Objectives: To assess non-invasive ventilation knowledge and skills among nurses and physicians in different contexts: equipment and contextual influences. Method: Cross-sectional, descriptive study in 4 intensive care units (ICU) (1 surgical, 3 medical-surgical), 1 postsurgical recovery unit, 2 emergency departments (ED) and 3 wards, in 4 hospitals (3 university, 1 community) with 407 professionals. A 13-item survey, validated in the setting, was applied (Kappa index, 0.97 (95% CI [.965-.975]). Results: Nurses (63.7% response); physicians (39% response). The overall percentage of correct responses was 50%. Scored from 1 to 5, with lower scores reflecting more knowledge, nurses scored 3.27 ±.5 vs 2.62 ±.5 physicians, respectively (mean difference,.65 (95% CI: .48-.82, P < .001). There were no differences between hospitals or units (P = .07 and P = .09). A notable percentage of respondents incorrectly identified the patient-ventilator synchronization strategy as "covering the expiratory port" (intentional leaks) and pressing the mask against the patient's face (unintentional leaks) (28.2% ICU, 22.5% ED, 8.3% postoperative resuscitation, 61.5% wards), with no difference between nurses and physicians (27.9% vs 23.4%, P = .6). Only 50% of nurse respondents correctly answered a question about measuring mask size and just 11.7% of the nurses knew the "2-finger fit" adjustment. Conclusions: There was no difference in nurses' and physicians' knowledge according to the setting studied. The lack of knowledge regarding NIV therapy depended on training received and material available. To reduce the existent confusion between intentional and nonintentional leak, the use of a single type of NIV supply and providing an appropriate level of training for nurses is recommended

Epidemiological changes of acute/recent human immunodeficiency virus type 1 infection in Barcelona, Spain (1997-2015): a prospective cohort study.

OBJECTIVE: To describe the epidemiology of acute/recent human immunodeficiency virus (HIV) infection over two decades in Barcelona (Spain). METHODS: Prospective, single-centre cohort including all patients with an acute/recent HIV infection (<180 days) since 1997. Patients were stratified into four periods. Phylogenetic analysis was performed to determine clusters of transmission. RESULTS: A total of 346 consecutive acute/recently infected patients were included. The annual proportion of recent infections among total new HIV diagnoses increased over time from 1% (29 out of 1964) to 8% (112 out of 1474) (p <0.001). Proportion of men who have sex with men (MSM) in the cohort increased from 62% (18 out of 29) to 89% (100 out of 112) (p <0.001). The proportion of migrants showed a non-significant increasing trend (24% (7 of 29) to 40% (45 of 112)) likewise the non-B subtype (0% to 22% (22 of 112)). The mean time from infection to diagnosis was 53.6 days (interquartile range (IQR) 50-57), comparable among all periods. Mean time from infection to treatment decreased over the years from 575 (IQR 467-683) to 471 (IQR 394-549) days (p <0.001) without significant differences between migrants and non-migrants (133 (IQR 71-411) versus 208 (IQR 90-523) days p 0.089). Almost 50% (152 of 311) of recently infected individuals were included in a cluster of transmission, and 92% (137 of 149) of them were MSM. CONCLUSION: The MSM population has progressively grown within acutely/recently infected patients in Barcelona, and is frequently involved in transmission clusters. Although the time between diagnosis and treatment has been reduced, the time between infection and diagnosis still needs to be shortened.

Analysis of cell-free DNA in maternal blood in screening for aneuploidies: updated meta-analysis.

OBJECTIVES: To review clinical validation or implementation studies of maternal blood cell-free (cf) DNA analysis and define the performance of screening for fetal trisomies 21, 18 and 13 and sex chromosome aneuploidies (SCA). METHODS: Searches of PubMed, EMBASE and The Cochrane Library were performed to identify all peer-reviewed articles on cfDNA testing in screening for aneuploidies between January 2011, when the first such study was published, and 31 December 2016. The inclusion criteria were peer-reviewed study reporting on clinical validation or implementation of maternal cfDNA testing in screening for aneuploidies, in which data on pregnancy outcome were provided for more than 85% of the study population. We excluded case-control studies, proof-of-principle articles and studies in which the laboratory scientists carrying out the tests were aware of fetal karyotype or pregnancy outcome. Pooled detection rates (DRs) and false-positive rates (FPRs) were calculated using bivariate random-effects regression models. RESULTS: In total, 35 relevant studies were identified and these were used for the meta-analysis on the performance of cfDNA testing in screening for aneuploidies. These studies reported cfDNA results in relation to fetal karyotype from invasive testing or clinical outcome. In the combined total of 1963 cases of trisomy 21 and 223 932 non-trisomy 21 singleton pregnancies, the weighted pooled DR and FPR were 99.7% (95% CI, 99.1-99.9%) and 0.04% (95% CI, 0.02-0.07%), respectively. In a total of 563 cases of trisomy 18 and 222 013 non-trisomy 18 singleton pregnancies, the weighted pooled DR and FPR were 97.9% (95% CI, 94.9-99.1%) and 0.04% (95% CI, 0.03-0.07%), respectively. In a total of 119 cases of trisomy 13 and 212 883 non-trisomy 13 singleton pregnancies, the weighted pooled DR and FPR were 99.0% (95% CI, 65.8-100%) and 0.04% (95% CI, 0.02-0.07%), respectively. In a total of 36 cases of monosomy X and 7676 unaffected singleton pregnancies, the weighted pooled DR and FPR were 95.8% (95% CI, 70.3-99.5%) and 0.14% (95% CI, 0.05-0.38%), respectively. In a combined total of 17 cases of SCA other than monosomy X and 5400 unaffected singleton pregnancies, the weighted pooled DR and FPR were 100% (95% CI, 83.6-100%) and 0.004% (95% CI, 0.0-0.08%), respectively. For twin pregnancies, in a total of 24 cases of trisomy 21 and 1111 non-trisomy 21 cases, the DR was 100% (95% CI, 95.2-100%) and FPR was 0.0% (95% CI, 0.0-0.003%), respectively. CONCLUSIONS: Screening by analysis of cfDNA in maternal blood in singleton pregnancies could detect > 99% of fetuses with trisomy 21, 98% of trisomy 18 and 99% of trisomy 13 at a combined FPR of 0.13%. The number of reported cases of SCA is too small for accurate assessment of performance of screening. In twin pregnancies, performance of screening for trisomy 21 is encouraging but the number of cases reported is small. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Outcome reporting across randomised controlled trials evaluating therapeutic interventions for pre-eclampsia.

BACKGROUND: Standardising outcome collection and reporting in pre-eclampsia trials requires an appraisal of current outcome reporting. OBJECTIVES: To map maternal and offspring outcome reporting across randomised trials evaluating therapeutic interventions for pre-eclampsia. SEARCH STRATEGY: Randomised trials were identified by searching bibliographical databases from inception to January 2016. SELECTION CRITERIA: Randomised controlled trials. DATA COLLECTION AND ANALYSIS: We systematically extracted and categorised outcome reporting. MAIN RESULTS: Seventy-nine randomised trials, reporting data from 31 615 maternal participants and 28 172 of their offspring, were included. Fifty-five different interventions were evaluated. Included trials reported 119 different outcomes, including 72 maternal outcomes and 47 offspring outcomes. Maternal outcomes were inconsistently reported across included trials; for example, 11 trials (14%) reported maternal mortality, reporting data from 12 422 participants, and 16 trials (20%) reported cardiovascular morbidity, reporting data from 14 963 maternal participants. Forty-three trials (54%) reported fetal outcomes and 23 trials (29%) reported neonatal outcomes. Twenty-eight trials (35%) reported offspring mortality. There was poor reporting of childhood outcomes: six trials (8%) reported neurodevelopmental outcomes. Less than half of included trials reported any relevant information regarding harms for maternal participants and their offspring. CONCLUSIONS: Most randomised trials evaluating interventions for pre-eclampsia are missing information on clinically important outcomes, and in particular have neglected to evaluate efficacy and safety in the offspring of participants. Developing and implementing a minimum data set, known as a core outcome set, in future pre-eclampsia trials could help to address these issues. TWEETABLE ABSTRACT: Future #preeclampsia research requires a core outcome set to reduce #research waste. @coreoutcomes @jamesmnduffy International Prospective Register of Systematic Reviews: CRD42015015529; www.crd.york.ac.uk/PROSPERO/display_record.aspID=CRD42015015529.

Optimising non-invasive mechanical ventilation: Which unit should care for these patients? A cohort study.

BACKGROUND: Use of noninvasive ventilation (NIV) has extended beyond intensive care units (ICUs), becoming usual practice in emergency departments (EDs) and general wards. OBJECTIVE: To analyse the relationship between nursing care and NIV outcome in different hospital units. DESIGN AND SETTINGS: Three university hospitals and one community hospital participated in a prospective observational cohort study. PARTICIPANTS: Ten units participated: 4 ICUs (1 surgical, 3 medical-surgical), 3 recovery (1 postsurgical, 2 EDs, 3 general wards). METHOD: Treatment success/failure, interface intolerance and complications were evaluated according to patient characteristics, nursing care provided, and procedures used. Complications analysed included bronchoaspiration, pneumothorax, skin lesions, inability to manage secretions, eye irritations, deteriorating level of consciousness, gastric distension, and excessive air losses around the mask. RESULTS: Of 387 patients, 194 (50.1%) were treated in ICU, 121 (31.3%) in ED, 38 (9.8%) postsurgery, and 34 (8.8%) in general wards. Regression analysis, adjusted for APACHE score and NIV indication, showed 3.3 times greater risk of NIV failure (95% CI [1.2-9.2]) in a university-hospital ICU with <50 NIV cases/year, compared to a community hospital ICU. In ICUs and general wards, NIV was suspended in 12% of patients due to interface intolerance. Acute-on-chronic lung diseases (ACLD) had lower risk of NIV failure (OR 0.2 [95% CI 0.06-0.69]) and lack of humidification was not associated with treatment failure (OR 0.2 [95% CI 0.1-0.4]). Poor secretion management was linked to pneumonia (OR 2.5 [95% CI 1.1-5.9]) and early weaning/extubation (OR 3.3 [95% CI 1.2-8.9]). Interface intolerance was associated with conventional ICU ventilators (OR 4.4 [95% CI 2.1-9.2]) and nasal skin lesions with excessive air losses (OR 2.4 [95% CI 1.1-5.3]), especially with oronasal masks (OR 3.5 [95% CI 1.1-11.3]). CONCLUSIONS: Acute respiratory failure patients with pneumonia admitted to general wards had increased interface intolerance and NIV failure. Rotating mask types could improve NIV success in any unit administering this therapy.

One-Year Follow-up of Children and Adolescents with Major Depressive Disorder: Relationship between Clinical Variables and Abcb1 Gene Polymorphisms.

Introduction: Differences in response to fluoxetine (FLX) may be influenced by certain genes that are involved in FLX transportation (ABCB1). We examined remission and recovery from the index episode in a cohort of patients treated with FLX, and also investigated associations between genetic variants in ABCB1 and remission, recovery, and suicide risk. Methods: This was a naturalistic 1-year follow-up study of 46 adolescents diagnosed with major depressive disorder (MDD). At 12 months they underwent a diagnostic interview with the K-SADS-PL. Results: It was found that remission was around 69.5% and recovery 56.5%. Remission and recovery were associated with lower scores on the CDI at baseline, with fewer readmissions and suicide attempts, and with lower scores on the CGI and higher scores on the GAF scale. No relationship was found between ABCB1 and remission or recovery. However, a significant association was observed between the G2677T ABCB1 polymorphism and suicide attempts. Conclusion: Other factors such as stressful events, family support, and other genetic factors are likely to be involved in MDD outcome.

Implantación de buenas prácticas en calidad y seguridad. Estudio descriptivo en una mutua laboral / Implementation of good quality and safety practices. Descriptive study in a occupational mutual health centre

Objetivo. Describir el nivel de implantación de elementos de buena atención sanitaria en una mutua. Método. Estudio descriptivo, transversal. Se encuestó al conjunto de 87 referentes de calidad de MC Mutual y una submuestra aleatoria de 54 sanitarios con destino en centros con entre 4 y 7 profesionales sanitarios. Los 23 elementos del cuestionario fueron seleccionados por su condición de ser identificados como buenas prácticas. Adicionalmente, los sujetos valoraron una serie de atributos que describían el nivel de calidad de los centros (escala de 0 a 10). Resultados. Respondieron 70 referentes y 27 profesionales (tasa respuesta del 80% y 50%, respectivamente). Entre ambos colectivos no hubo diferencias en la valoración de los atributos de calidad. Identificaron como áreas de mejora: uso de guías de práctica (7,6/10), competencia científico-técnica (7,5/10) y satisfacción de los pacientes (7,7/10). Consideraron con alta implantación: disponibilidad y accesibilidad a la historia clínica común, consentimiento informado, disponibilidad de solución hidroalcohólica y sistema de registro de alergias. Con baja implantación: formación e investigación, planes de mejoras en equipamientos y tecnología, adhesión a guías de práctica clínica y mapas de riesgos. Conclusión. Mientras se logra un alto nivel de implantación en elementos de buena práctica relacionados con equipamientos y recursos, otros aspectos relacionados con actitudes hacia la calidad y seguridad requieren de mayor atención, como sucede en otras organizaciones sanitarias (AU)

Objective. To describe the level of implementation of quality and safety good practice elements in a Mutual Society health centre. Method. A Cross-sectional study was conducted to assess the level of implementation of good practices using a questionnaire. Some quality dimensions were also assessed (scale 0 to 10) by a set of 87 quality coordinators of health centres and a random sample of 54 healthcare professionals working in small centres. Results. Seventy quality coordinators and 27 professionals replied (response rates 80% and 50%, respectively. There were no differences in the assessment of quality attributes between both groups. They identified as areas for improvement: use of practice guidelines (7.6/10), scientific and technical skills (7.5/10), and patient satisfaction (7.7/10). Availability and accessibility to clinical reports, informed consent, availability of hydro-alcoholic solution, and to record allergies, were considered of high importance to be implemented, with training and research, improvements in equipment and technology plans, adherence to clinical practice guidelines and the preparation of risk maps, being of less importance. Conclusion. The good practices related to equipment and resources have a higher likelihood to be implemented, meanwhile those related to quality and safety attitudes have more barriers before being implemented. The mutual has a similar behaviour than other healthcare institutions (AU)

Diagnostic accuracy of cancer antigen 125 for endometriosis: a systematic review and meta-analysis.

BACKGROUND: The development of a non-invasive and accurate diagnostic biomarker for endometriosis is urgently needed. OBJECTIVE: Evaluate the diagnostic accuracy of serum cancer antigen 125 (CA 125) for endometriosis. SEARCH STRATEGY: We searched EMBASE, MEDLINE, and Web of Science from inception to January 2016. SELECTION CRITERIA: Diagnostic accuracy studies of serum CA 125 (index test) for histologically confirmed endometriosis (reference standard) were included. DATA COLLECTION AND ANALYSIS: Two authors independently selected trials, extracted study characteristics and data. Methodological quality was assessed using Quality Assessment of Comparative Diagnostic Accuracy Studies (QUADAS-2) checklist. MAIN RESULTS: Twenty-two studies (16 cohort, six case-control), 3626 participants, were identified. Bivariate hierarchical models were used to pool accuracy data of 14 studies (2920 participants) using CA 125 ≥ 30 units/ml. Pooled specificity was 93% (95% CI 89-95%) and sensitivity 52% (95% CI 38-66%). CA 125 was significantly more sensitive for the diagnosis of moderate or severe endometriosis compared with minimal disease (63%, 95% CI 47-77% versus 24%, 95%CI 19-32%, P-value = 0.001). CONCLUSIONS: CA 125 performs well as a rule-in test facilitating expedited diagnosis and ensuring investigation and treatment can be confidently tailored for the management of endometriosis. Unfortunately, a negative test, CA 125 < 30 units/ml, is unable to rule out endometriosis. TWEETABLE ABSTRACT: Blood test CA 125: a rule-in test for the diagnosis of women presenting with symptoms of endometriosis.

MicroRNA Profile in CD8+ T-Lymphocytes from HIV-Infected Individuals: Relationship with Antiviral Immune Response and Disease Progression.

BACKGROUND: The relationship between host microRNAs (miRNA), viral control and immune response has not yet been elucidated in the field of HIV. The aim of this study was to assess the differential miRNA profile in CD8+ T-cells between HIV-infected individuals who differ in terms of viral replication control and immune response. METHODS: miRNA profile from resting and CD3/CD28-stimulated CD8+ T-cells from uninfected individuals (HIV-, n = 11), Elite Controllers (EC, n = 15), Viremic Controllers (VC, n = 15), Viremic Progressors (VP, n = 13) and HIV-infected patients on therapy (ART, n = 14) was assessed using Affymetrix miRNA 3.1 arrays. After background correction, quantile normalization and median polish summarization, normalized data were fit to a linear model. The analysis comprised: resting samples between groups; stimulated samples between groups; and stimulated versus resting samples within each group. Enrichment analyses of the putative target genes were perfomed using bioinformatic algorithms. RESULTS: A downregulated miRNA pattern was observed when resting samples from all infected groups were compared to HIV-. A miRNA downregulation was also observed when stimulated samples from EC, ART and HIV- groups were compared to VP, being hsa-miR-4492 the most downregulated. Although a preferential miRNA downregulation was observed when stimulated samples were compared to the respective resting samples, VP presented a differential miRNA expression pattern. In fact, hsa-miR-155 and hsa-miR-181a were downregulated in VP whereas in the other groups, either an upregulation or no differences were observed after stimulation, respectively. Overall, functional enrichment analysis revealed that the predicted target genes were involved in signal transduction pathways, metabolic regulation, apoptosis, and immune response. CONCLUSIONS: Resting CD8+ T-cells do not exhibit a differential miRNA expression between HIV-infected individuals but they do differ from non-infected individuals. Moreover, a specific miRNA pattern is present in stimulated CD8+ T-cells from VP which could reflect a detrimental pattern in terms of CD8+ T-cell immune response.

Clinical significance of psychiatric comorbidity in children and adolescents with obsessive-compulsive disorder: subtyping a complex disorder.

A promising approach in relation to reducing phenotypic heterogeneity involves the identification of homogeneous subtypes of OCD based on age of onset, gender, clinical course and comorbidity. This study aims to assess the sociodemographic characteristics and clinical features of OCD patients in relation to gender and the presence or absence of another comorbid disorder. The sample comprised 112 children and adolescents of both sexes and aged 8-18 years, all of whom had a diagnosis of OCD. Overall, 67 % of OCD patients had one comorbid diagnosis, 20.5 % had two such diagnoses and 2.6 % had three comorbid diagnoses. The group of OCD patients with a comorbid neurodevelopmental disorder had significantly more family history of OCD in parents (p = .049), as compared with the no comorbidity group and the group with a comorbid internalizing disorder, and they also showed a greater predominance of males (p = .013) than did the group with a comorbid internalizing disorder. The group of OCD patients with internalizing comorbidity had a later age of onset of OCD (p = .001) compared with both the other groups. Although the initial severity was similar in all three groups, the need for pharmacological treatment and for hospitalization due to OCD symptomatology was greater in the groups with a comorbid neurodevelopmental disorder (p = .038 and p = .009, respectively) and a comorbid internalizing disorder (p = .008 and p = .004, respectively) than in the group without comorbidity. Our findings suggest that two subtypes of OCD can be defined on the basis of the comorbid pathology presented. The identification of different subtypes according to comorbidity is potentially useful in terms of understanding clinical variations, as well as in relation to treatment management and the use of therapeutic resources.

[Critical reading of systematic reviews and meta-analyses about diagnostic imaging]. / Lectura crítica de revisiones sistemáticas y metanálisis en el diagnóstico por imagen.

Systematic reviews of diagnostic validity have been proposed as the best methodological tool to integrate all the available evidence and to help physicians decide whether to use a given diagnostic test. These studies aim to synthesize the results obtained in different primary studies into a couple of indices, generally sensitivity and specificity, or into a summary receiver operating characteristic (ROC) curve. Although there is a certain parallelism with reviews about the efficacy of therapeutic interventions, reviews of diagnostic validity have certain peculiarities that add complexity to the analysis and interpretation of the results. This article emphasizes the methodological aspects that make it possible to critically assess the extent to which the results of a review of the validity of diagnostic tests are valid and provides rudimentary knowledge of the statistics necessary to understand the results.

Análisis comparativo de los conocimientos en ventilación mecánica no invasiva de profesionales de cuidados intensivos / Intensive care unit profesionals's knowledge about non invasive ventilation comparative analysis

Objetivo: La bibliografía destaca la falta de protocolos de ventilación mecánica no invasiva (VNI) y la variabilidad de conocimientos entre unidades y hospitales, por lo que se pretende comparar los conocimientos en VNI en enfermeras de 4 UCI polivalentes y una quirúrgica. Métodos: Estudio descriptivo multicéntrico en hospitales universitarios de nivel 3. Se diseñó una encuesta ad-hoc, con fiabilidad interobservador Kappa = 0,9. Contestar la encuesta era indicación de consentimiento informado. Análisis con Chi cuadrado. Resultados: Respondieron 117 (65%) enfermeras, con 11 ± 9,7 años de experiencia en UCI y 9,2 ± 7,2 en uso de VNI. Una de las UCI polivalentes había iniciado la VNI una media de 6 años más tarde que las otras (IC 95% [3,3 a 8,6], P <0,001).Solo el 23,1% de las enfermeras colocaría una mascarilla sin puerto espiratorio en respirador convencional, el resto cualquier mascarilla buconasal. El 12,7% cree que la mascarilla debe permitir el paso de 2 dedos mientras que el 29% apretaría la máscara a la cara del paciente y taparían el puerto espiratorio para facilitar la sincronización con el respirador. En la UCI quirúrgica se identifica mayoritariamente la agitación como una complicación de la VNI comparado con las polivalentes (31,6 vs. 1,8%, P < 0,001).El 56,4% de las enfermeras no consideran la fisioterapia respiratoria como un cuidado enfermero, sin diferencia entre unidades. Conclusiones: El conocimiento en tipos de interfase es muy dependiente del material de la unidad. Falta formación para detectar complicaciones de VNI como la agitación y el manejo de secreciones

Aims: The literature highlights the lack of noninvasive vntilation (NIV) protocols and the variability of the knowledge of NIV between intensive care units (ICU) and hospitals, so we want to compare NIV nurses's Knowledge from 4 multipurpose ICU and one surgical ICU. Methods: Multicenter, crosscutting, descriptive study in three university hospitals. The survey instrument was validated in a pilot test, and the calculated Kappa index was 0.9. Returning a completed survey is an indication of informed consent. Analysis by Chi square test. Results: 117 responded (65%) nurses, 11 ± 9.7 years of experience in ICU and 9.2 ± 7.2 in use of NIV. One of the multipurpose ICU, was initiated NIV an average of 6 years later than the others (95% CI [3.3 to 8.6], P < .001). Only 23.1% of nurses would place a non-vented mask (with no exhalation port) by conventional ventilator, the rest any kind of face mask. 12.7% believed that the mask must be adjusted to the '2-finger' fit while 29% would seal the mask to the patient's face and cover the mask opening where air escapes to facilitate patient/ventilator synchronization. In the surgical ICU agitation identifies mostly as a complication of NIV compared with multipurpose UCIs (31.6% vs 1.8%, P < .001). 56.4% of nurses do not consider respiratory physiotherapy as nursing care, with no difference between units. Conclusions: Knowledge about types of interface is very dependent on the material of the unit. More training for complications of NIV as agitation and handling secretions it is necessary
