Short-term trajectories of workplace bullying and its impact on strain: A latent class growth modeling approach

The aim of this weekly diary study was (a) to identify trajectories of workplace bullying over time and (b) to examine the association of each cluster with strain indicators (i.e., insomnia and anxiety/depression). A sample of 286 employees during 4 weeks of data was used (N occasions = 1,144). Results of latent class growth modeling showed that 3 trajectories could be identified: a nonbullying trajectory, which comprised 90.9% of the sample; an inverted U trajectory; and a delayed increase bullying trajectory; the latter two each had 4.2% of the participants. We found a significant interaction between time and trajectories when predicting insomnia and anxiety/depression, with each strain showing a differential pattern with each trajectory. It seems that the negative effects on insomnia are long-lasting and remain after bullying has already decreased. In the case of anxiety and depression, when bullying decreases strain indicators also decrease. In this study, by examining trajectories of bullying at work over time and their associations with strain, we provide new insights into the temporal dynamics of workplace bullying

Desarrollo y validación de la versión española del Inventario de Habilidades Políticas: English

Background: The Political Skills Inventory (PSI) is a measurement tool for assessing four dimensions associated with political skills: social astuteness, interpersonal influence, networking ability and apparent sincerity (Ferris, 2005). Method: In the present study, multi-sample and multi-method, we developed and analyzed the psychometric properties of the Spanish version of the (PSI), by performing both exploratory and confirmatory factor analyses. Additionally, a longitudinal reliability test and a sex factorial invariance test were performed. Results: Cronbach's alpha and omega indices revealed satisfactory reliability and exploratory factor analyses extracted the four original factors as reported in other studies (N = 309). Confirmatory factorial analyses confirmed that the four-factor solution presented the best fit to our data (N = 248). Conclusions: We add new evidence for time and sex invariance of the measure, showing that the PSI can be considered a stable and valid measure over time and across sex.Introducción: El inventario de habilidades políticas (PSI, siglas en inglés) es una medida para calibrar cuatro dimensiones relacionadas con este constructo: la astucia social, la capacidad de influencia interpersonal, la habilidad para establecer contactos y la sinceridad aparente (Ferris, 2005). Método: En el presente estudio, multi-muestra y multi-método, sendos análisis factorial exploratorio y confirmatorio se han llevado a cabo para desarrollar y testar las propiedades psicométricas de la versión española del PSI. Adicionalmente, se llevó a cabo un test de fiabilidad longitudinal y un análisis de invarianza relativo al género. Resultados: Los índices alpha de Cronbach y omega revelaron un grado de fiabilidad satisfactoria. El análisis factorial exploratorio extrajo los cuatro factores de la versión original, tal y como ya ha sido reportado en otros estudios (N = 309). El análisis factorial confirmatorio confirmó que el ajuste de dicha estructura fue el mejor frente a los datos (N = 248). Conclusiones: Con este estudio se añade evidencia al estudio de la invarianza de género y la estabilidad temporal de esta medida, mostrando que la versión española del PSI puede ser considerada una medida estable y válida a través del tiempo y relativa al género

Effective Educational Practices and Students' Well-being: The Mediating Role of Students' Self-efficacy

Effective educational practices aim to promote students’ academic achievement; however, they also have an impact on students’ well-being which is a growing topic of interest in educational research. In a sample of 2242 students (5th to 10th grades) nested in 104 classrooms from Spanish schools, we have tested the mediating role of students’ self-efficacy on the relationship between effective educational practices and both students’ well-being and academic performance. Analyses were run at student and class levels, by performing a multilevel mediation structural equation model with cross-sectional data. Results supported a partial mediation model at the individual level, in which effective educational practices had a direct and indirect effect on students’ well-being, and indirect effect on academic performance in math and language through self-efficacy. At the group level, results support a full mediation model of the effect of effective educational practices in class well-being and in class math performance (but not in language), mediated by the group mean of self-efficacy. These findings suggest the importance of educational practices in increasing self-efficacy beliefs on their students, as a source to increase students’ well-being and academic performance

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Predictive Power of the "Trigger Tool" for the detection of adverse events in general surgery: a multicenter observational validation study

Background In spite of the global implementation of standardized surgical safety checklists and evidence-based practices, general surgery remains associated with a high residual risk of preventable perioperative complications and adverse events. This study was designed to validate the hypothesis that a new “Trigger Tool” represents a sensitive predictor of adverse events in general surgery. Methods An observational multicenter validation study was performed among 31 hospitals in Spain. The previously described “Trigger Tool” based on 40 specific triggers was applied to validate the predictive power of predicting adverse events in the perioperative care of surgical patients. A prediction model was used by means of a binary logistic regression analysis. Results The prevalence of adverse events among a total of 1,132 surgical cases included in this study was 31.53%. The “Trigger Tool” had a sensitivity and specificity of 86.27% and 79.55% respectively for predicting these adverse events. A total of 12 selected triggers of overall 40 triggers were identified for optimizing the predictive power of the “Trigger Tool”. Conclusions The “Trigger Tool” has a high predictive capacity for predicting adverse events in surgical procedures. We recommend a revision of the original 40 triggers to 12 selected triggers to optimize the predictive power of this tool, which will have to be validated in future studies

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Resumen tomado de la publicaciónEscala de Autoeficacia del Profesorado según las percepciones del alumnado: un enfoque multinivel. Antecedentes: existen evidencias del papel que las prácticas educativas de los docentes tienen en el rendimiento escolar y el bienestar de los estudiantes. Sin embargo, faltan medidas válidas en español que permitan estudiar las prácticas educativas efectivas a partir de las percepciones de los estudiantes. Por ello, este estudio tiene como objetivo proporcionar una escala válida y fiable para medir las prácticas educativas eficaces en entornos escolares (STEPS). Método: analizamos, en una muestra de 2.242 estudiantes anidados en 104 aulas de 22 escuelas españolas, la consistencia y fiabilidad interna de la escala, la solución e invariancia de factores y la validez de criterio mediante el uso de un enfoque multinivel. Resultados: los resultados indicaron que la escala exhibió una buena fiabilidad de acuerdo con el coeficiente omega (intra = .86, e inter = .98); el análisis factorial confirmatorio multinivel (MCFA) reveló una estructura jerárquica: gestión del aula, estrategias de instrucción y participación de los estudiantes, como factores de primer orden; y un factor general de segundo orden etiquetado como prácticas educativas efectivas. Además, las prácticas educativas efectivas se asociaron con mejor autoestima de los estudiantes. Conclusiones: este estudio ofrece un instrumento fiable y válido, STEPS, para medir prácticas educativas efectivas.ES
