RESUMEN

As observed in other mental health difficulties, behavioural addiction is a complex construct with several potential predisposing factors, which include biological factors (e.g., genetic predispositions), psychological factors (e.g., personality traits), and social factors (e.g., family, and social history). One factor that may play a significant role in both developing and perpetuating behavioural addiction is the activation of early maladaptive schemas (EMSs). The aim of the present review was to synthesize the evidence concerning the relationship between behavioural addiction and EMSs. A comprehensive literature search using keywords and subject headings was performed with three electronic databases, resulting in 20 studies that met the inclusion criteria. In relation to specific behavioural addiction, the 20 studies examined: binge-eating/food addiction (n = 6), sexual addiction/compulsive sexual behaviours (n = 3), multiple addictive behaviours (n = 2), internet addiction (n = 2), smartphone addiction (n = 2), social networking/Facebook addiction (n = 2), exercise dependence (n = 1), gambling (n = 1), and videogame addiction (n = 1). The patterns of association between EMS and behavioural addiction were examined in both clinical and non-clinical population. The 'Disconnection and Rejection' domain was the most strongly related schema domain across all addictive behaviours, followed by 'Impaired Limits'. The present review suggests a positive relationship between schema activation and several addictive behaviours, including addictions to gambling, gaming, social media use sex, exercise, and food. The clinical implications of the findings are discussed, but further research is needed to inform treatment plans and interventions for those who struggle with behavioural addictions.

RESUMEN

OBJECTIVE: to assess the effectiveness of the interventions targeted at preventing and reducing the workplace violence suffered by health and support professionals. METHOD: a systematic review with meta-analysis conducted in eight databases and in the gray literature. Risk of bias was assessed by means of the Cochrane tools and certainty of the evidence, through Grading of Recommendations Assessment, Development and Evaluation. The analysis was performed in a descriptive manner and through the meta-analysis, including a heterogeneity assessment. RESULTS: a total of 11 randomized and quasi-randomized studies were eligible, of which six (54.5%) implemented individual skills, four used a multiple approach (36.4%) and one (9.1%) resorted to governmental actions. Four studies (36.4%) exerted a positive and significant effect on reducing violence. Risk of bias was classified as high or uncertain. The meta-analysis was performed with two studies that tested individual skill (intervention group) versus individual skill (comparator group), although there was no scientific evidence (95% CI: -0.41 - 0.25, p=0.64) for the violence prevention/reduction outcome. CONCLUSION: this review did not obtain a high level of evidence in the prevention or reduction of workplace violence. The reduced number of randomized trials, the lack of studies with low risk of bias and the high consistency may have been factors that hindered recommending effective interventions.

RESUMEN

Resumo Objetivo: avaliar a efetividade das intervenções direcionadas à prevenção e redução da violência no trabalho sofrida por profissionais de saúde e apoio. Método: revisão sistemática com metanálise realizada em oito bases de dados e na literatura cinzenta. O risco de viés foi realizado por meio das ferramentas da Cochrane e a certeza da evidência pelo Grading of Recommendations Assessment, Development and Evaluation. A análise foi realizada de forma descritiva e pela metanálise, incluindo avaliação da heterogeneidade. Resultados: 11 estudos aleatorizados e quasi-aleatorizados foram elegíveis, dos quais seis estudos (54,5%) implementaram habilidades individuais, quatro multiabordagem (36,4%) e um (9,1%) ações governamentais. Quatro estudos (36,4%) tiveram efeito positivo e significativo na redução da violência. O risco de viés foi classificado como alto ou incerto. A metanálise foi realizada com dois estudos que testaram habilidade individual (grupo intervenção) versus habilidade individual (grupo comparador), porém não houve evidência científica (IC 95%: -0,41 a 0,25, p=0,64) para o desfecho prevenção/redução da violência. Conclusão: esta revisão não obteve alta evidência na prevenção ou redução da violência no trabalho. O número reduzido de ensaios aleatorizados, a falta de estudos com baixo risco de viés e a alta consistência podem ter sido fatores dificultadores para recomendar intervenções efetivas.

RESUMEN

This study aims to explore biochemical changes in saliva during cardiorespiratory exercise using attenuated-total-reflectance-Fourier-transform-infrared-spectroscopy (ATR-FTIR). Saliva and blood samples were obtained from six athletes at rest, and after running at speeds of 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 kilometers-per-hour (km/h) on a treadmill (maximal stress test). Saliva ATR-FTIR spectra were analyzed using deconvolution and multivariate analysis. Area-under-the-curve calculations suggest differential changes in glucose, lactate, protein, lipids, carbohydrate and phosphate content in saliva during the test. Increases in glucose and lactate levels with increasing speeds were verified by simultaneous measurement of blood glucose and lactate levels using standard equipment (Roche®). Multivariate principal-component-analysis (PCA) showed discrete clusters for low (rest-14 km/h) and high (15 - 20 km/h) speeds, and PCA-linear-discriminant-analysis showed 100% classification of 18 - 20 km/h as high speed. Overall, results suggest the possibility of using this non-invasive saliva-based ATR-FTIR method for biochemical assessment during sports exercise and stress tests.

RESUMEN

INTRODUCTION: The frequency of workplace violence has increased significantly across several countries, with short- and long-term effects on workers' health. Within the health care sector, nursing professionals are the most exposed to workplace violence, since they provide direct assistance to patients on a 24-hour basis. OBJECTIVES: To identify the types of occupational violence experienced by nursing professionals. METHODS: This was a descriptive, quantitative study of 55 nursing professionals in the emergency unit of a public hospital. Data were collected between April and June 2018 through the Questionnaire for Workplace Violence Experienced or Witnessed by Nursing Professionals. Categorical variables were presented as frequencies and percentages, while continuous variables were described using measures of central tendency and dispersion. RESULTS: A total of 49 (88.9%) participants had experienced workplace violence, with 21 (38%) suffering verbal abuse; 14 (25.4%) experiencing mobbing; 6 (11%) reporting physical violence; 5 (9.1%) suffering sexual harassment; and 3 (5.4%) reporting racial discrimination. Furthermore, 44 (90%) of these individuals reported that the incidents of violence could have been prevented. CONCLUSIONS: The types of violence observed included physical aggression, verbal abuse, sexual harassment and racial discrimination, with verbal abuse being the most commonly reported. These acts were perpetrated by patients and their families, as well as colleagues and supervisors. Violence prevention strategies should be implemented in institutions in order to provide a safe working environment.

RESUMEN

INTRODUCTION: Occupational violence affects several categories of workers; however, the health sector category has been considered at a high risk, exposing workers to physical and psychological abuse. Thus, occupational violence has decreased the quality of care in health service. This review aims to evaluate the effectiveness of interventions for the prevention and reduction of occupational violence against health professionals. METHODS AND ANALYSIS: This protocol is consistent with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Searches will be conducted in PubMed, Embase, Cochrane Library, LILACS, Web of Science, Scopus, CINAHL and LIVIVO along with a comprehensive review of grey literature. The search will be conducted on August 1 st 2020, without language and time restrictions. Following the eligibility criteria, two independent reviewers will select the titles and abstracts and subsequently screen the full articles. If necessary, a third reviewer will assess any disagreements. All references will be imported into EndNote, and any duplicates will be removed. The data will be extracted using an extraction-based form from Cochrane. Statistical analyses will be performed using the software Cochrane Review Manager, and a meta-analysis will be performed if possible for the statistical combination of at least two studies. The risk of bias of the randomised clinical trials will be evaluated by the Risk of Bias tool from Cochrane, and the risk of bias of the non-randomised intervention studies will be evaluated using the Downs and Black scale. The quality of the evidence and strength of the classification recommendations will be assessed by the Grading of Recommendations, Assessment, Development and Evaluation. ETHICS AND DISSEMINATION: This review will not evaluate individual patient information and therefore does not require ethical approval. The results will be disseminated through publications in peer-reviewed journals, presentations at conferences and the doctoral thesis of the leading author. PROSPERO REGISTRATION NUMBER: CRD42018111383.

RESUMEN

Objetivou-se identificar concentrações de hidrocarbonetos policíclicos aromáticos provenientes da fumaça do eletrocautério nas salas operatórias, correlacionando estas concentrações com o tempo de uso do eletrocautério e cirúrgico. Trata-se de um estudo de campo, transversal e quantitativo, realizado em 50 atos cirúrgicos do aparelho digestivo, entre abril e julho de 2015, em hospital universitário no estado do Paraná. Foram coletados hidrocarbonetos por meio de uma bomba de sucção e determinados por cromatografia liquida. Estes compostos foram encontrados com média de 0,0058 mg.m-³ e mediana de 0,0049 mg.m-³. O tempo médio cirúrgico e de uso do eletrocautério foram de 136 minutos e 220,5 segundos, respectivamente. O teste de correlação de Spearman foi de -0,512 entre as variáveis concentrações e tempo cirúrgico e de -0,183 entre as concentrações e tempo de uso do eletrocautério. Conclui-se que existem hidrocarbonetos e há baixa correlação entre a produção destes compostos e tempo de uso do eletrocautério (AU).

The objective was to identify concentrations of polycyclic aromatic hydrocarbons produced by electrocautery smoke in operating rooms, correlating these concentrations with time of electrocautery and surgical use. This is a cross-sectional and quantitative field study carried out in 50 gastrointestinal surgical procedures, between April and July 2015, in a university hospital in the state of Paraná. Hydrocarbons were collected using a suction pump and measurements were determined through liquid chromatography. These compounds were found to have an average of 0.0058 mg.m-3 and a mean of 0.0049 mg.m-3. The mean surgical time and electrocautery use were 136 minutes and 220.5 seconds, respectively. The Spearman correlation test was -0.512 between concentration variables and surgical time, and -0.183 between the concentrations and electrocautery use. The conclusion was the presence of hydrocarbons and a low correlation between the production of these compounds and the electrocautery usage time (AU).

RESUMEN

The purpose of this study was to analyse the physical and technical performances of professional tennis players during official matches. The trajectories of eight players were obtained during matches, using an automatic tracking method. The distances covered and technical performances were analysed for the first and second sets. The athletes covered (mean ± standard deviation) a total of 1702.4 ± 448.2 m in the first set, 1457.6 ± 678.1 m in the second set and 3160.0 ± 880.1 in the entire match. No differences were found between the sets for the physical variables (lateral and forward displacements, distance covered per rally, per game and per set, and the percentage of time spent in each range of velocity). However, the distances covered by the athletes during the rallies in which they were serving (median = 5.2; interquartile range (IQR) = 6.7 m) were statistically smaller than when they were returning (median = 6.2; IQR = 7.7 m). Forehand ground stroke proficiency decreased from the first (mean ± standard deviation: 75.2 ± 4.11%) to the second set (mean ± standard deviation = 65.5 ± 14.3%). In conclusion, tennis players did not present reduced physical performance from the first to the second set.

RESUMEN

An epidemiological inquiry of humancysticercosis due to Taenia solium was carried out in Lagamar, Minas Gerais State, Brazil, in 1992. A survey of 1109 houses with 3344 inhabitants was made. The inquiry included 875 (86 per cent) families and the questionnaire was answered by an informer, who was the father in 80 per cent of the cases. One hundred pigsties, sheltering 406 swines in extremely precarious conditions, were found in 100 (11.4 per cent) houses. A history on taeniasis in some member of the family was verified in 300 (34.2 per cent) houses. A history of seizures was referred to by 125 (14.2 per cent) of families. The outset of convulsion in adult age was characterized in 39 (37.8 per cent) families. A history of mental disorder was reported in 53 (6.0 per cent) of houses. Stool examinations were positive for Taenia spp in 24 (1.3 per cent) of samples examined per cent.

RESUMEN

The systemic reaction to severe trauma and/or infection, acute phase response (APR), are often associated with immunosuppression and reactivation of chronic latent infection. Our main purpose was to verify, in a group of 71 autopsied chronic chagasic with or without APR, the frequency of T. cruzi nests in the central vein of adrenal gland (CVAG). APR, defined by: 1) death secondary to sepsis and/or trauma plus, 2) bleeding stress gastric ulcerations or 3) spleen reactional state or 4) liver steatosis, was observed in 30 chronic chagasic (APR+). Weight, height and body mass index (BMI) were obtained. APR(+) chronic chagasic had worse nutritional status than APR(-) ones: weight = 49.0 vs 54.5 kg; BMI = 17.5 vs 20.6 kg/m2 (median p < 0.05). CVAG T. cruzi nests frequency were similar (43.3 per cent and 43.9 per cent , respectively) between both Groups. We conclude that APR(+) chronic chagasic had worse nutritional status than APR(-) ones, and that APR development did not change the CVAG T. cruzi nests frequency
