Contact precautions in Intensive Care Units: facilitating and inhibiting factors for professionals' adherence

Objetivou-se identificar os fatores que facilitam ou dificultam a adesão às precauções de contato, por parte de profissionais de um Centro de Terapia Intensiva de hospital geral. Tratou-se de um estudo transversal, realizado de maio a outubro de 2007, utilizando-se um questionário semi-estruturado para coleta de dados. Participaram do estudo 102 profissionais: técnico de enfermagem (54,9%), enfermeiro (12,7%), médico preceptor (10,8%), fisioterapeuta aprimorando (8,8%), fisioterapeuta preceptor (7,8%) e médico residente (4,9%). Os fatores dificultadores para a adesão à higienização das mãos foram o esquecimento, falta de conhecimento, distância da pia, irritação da pele e falta de materiais. O uso do capote apresentou maior dificuldade (45%) pela sua ausência no box, acondicionamento inadequado, calor, e ao seu uso coletivo. O uso de luvas foi a conduta de maior facilidade na prática cotidiana. Os resultados deste estudo apontam a necessidade de implementar medidas de precaução a fim de minimizar a disseminação de microrganismos resistentes.Este estudio tuvo por objetivo identificar los factores facilitadores y limitantes de la adhesión a las precauciones de contacto por parte de los profesionales de la Unidad de Terapia Intensiva de un hospital general.

Los factores limitantes para la adhesión a la higienización de manos fueron: el olvido, la falta de conocimiento, la distancia hasta los lavatorios, irritación de la piel y falta de materiales. El uso de guardapolvos y similares presentó mayor dificultad (45%) por su ausencia en el box, acondicionamiento inadecuado, calor y uso colectivo. La utilización de guantes fue la conducta de mayor aceptación en la práctica cotidiana. Los resultados de este estudio indican la necesidad de implementar medidas de precaución para minimizar la propagación de microorganismos resistentes.The objective of this study was to identify facilitating and limiting factors for professionals' compliance with contact precautions in an intensive care unit of a general hospital. This cross-sectional study was performed from May to October 2007, using a semi-structured questionnaire for data collection. Participants were 102 professionals, as follows: nursing technician (54.9%), nurse (12.7%), preceptor physician (10.8%), apprentice physiotherapist (8.8%), preceptor physiotherapist (7.8%) and resident physician (4.9%). The limiting factors for compliance with hand cleansing were forgetting, lack of knowledge, distance from sink, skin irritation, and lack of materials. The use of scrubs presented the most difficulty (45%) because they were not available at the shower box, were inappropriately stored, and due to the heat and collective use. Glove use was the practice most easily conducted in everyday practice. Results show the need to implement precaution measures to minimize the dissemination of resistant microorganisms

Conocimiento y comportamiento de los profesionales de un centro de terapia intensiva en relación a la adopción de las precauciones de contacto

This study aimed to assess the knowledge and behavior of professionals working in Intensive Care Units (ICU) related to the adoption of contact precautions for the control of hospital infections (HI). This cross-sectional study used a semi-structured questionnaire to collect data. Descriptive and multivariate analyses were carried out, including logistic regression and decision tree using CHAID algorithm. A total of 102 professionals participated in the study, of whom 36.3% presented appropriate knowledge and 51% appropriate behavior in relation to HI control measures. Nursing professionals had almost four times more chance (OR = 3.58, CI 1.48-8.68) of presenting appropriate behavior than the remaining professionals. The multivariate analysis did not reveal variables associated with knowledge. No statistically significant association was found between knowledge and behavior (p = 0.196). These results suggest the need to implement educational activities so as to permit a balance between theory and professionals' practice concerning HI preventive measures, aiming to improve knowledge and behavior.El objetivo fue evaluar el conocimiento y comportamiento de los profesionales de un CTI en relación a la adopción de precauciones de contacto para el control de las infecciones hospitalarias (IH).

Biomarkers of severity and chronification in chikungunya fever: a systematic review and meta-analysis

Currently, there are no biomarkers for Chikungunya fever (CHIK) in clinical practice that can accurately predict the severity or chronification of the disease. The aim of this study is to evaluate the existing literature on biomarkers related to the severity and chronification of CHIK. In this sense, a systematic review was conducted based on the PRISMA Statement guideline. Articles that described the association of biomarkers with the evolution of the disease (severity or chronification), published until August 20th 2019 were considered eligible. The search was carried out in the PubMed, Scopus, Virtual Health Library (VHL) and Science Direct databases. After searching the databases, 17 articles were added to the review, and after analyzing the articles, several biomarkers were associated with severity, such as increased levels of IL-6, IP-10, IL-1b, MIG, MCP-1, and reduced levels of RANTES and IL-8 or chronification, such as increased levels of IL-6, TNF-α, MCP-1, IL-12, INF-α, IL-13, INF-γ, GM-CSF, CRP, IL-1a, IL-15, Factor VII, IP-10, IL-10, IL-4, IL-1RA, IL-8, MIP-1α, MIP-1β, ferritin, MIG, ESR, NO, malondialdehyde, and reduced levels of RANTES, ferritin, eotaxin, HGF, IL-27, IL-17A, IL-29, TGF-β, IL-10, and thiols. IL-6, CRP and TNF-α were included in the meta-analysis to assess the relationship with chronification, although they did not reach statistical significance. It was concluded that several biomarkers showed a relationship with severity and chronification of CHIK; the search for these biomarkers can reveal prognostic factors and important therapeutic targets for the treatment of the disease

Quality of life in patients with Chagas disease and the instrument used: an integrative review

Chagas disease (CD) is a neglected tropical highly morbid disease that can have a negative impact on the quality of life (QoL). The purpose of this study was to conduct an integrative review to analyze the QoL of patients with CD in the chronic phase of the disease, as well as the instruments used and the effect of different interventions. The review was carried out based on the criteria and recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes guideline (PRISMA) using the PubMed, Scopus, Web of Science and Science Direct databases. An analysis of the reference list of the included articles was also carried out. Publications in all languages have been included. Two independent reviewers selected the eligible articles and extracted the data. A total of 1,479 articles were identified, and after applying the inclusion criteria 18 articles were included. Four different instruments were used to assess QoL and the most used was the Minnesota Living with Heart Failure Questionnaire (MLWHFQ) [33.3% (n = 6)]. Investigations involving intervention showed a positive impact on the patients’ QoL, and the Environment domain had the lowest score. Heterogeneity of instruments and lack of methodology standardization for assessing QoL was observed. QoL proved to be an important indicator for the planning and monitoring of patients with CD, however it is suggested that the instruments for its assessment should be the ones recommended by the validation studies. This process will allow the comparison of data between investigations

Longitudinal study of patients with chronic Chagas cardiomyopathy in Brazil (SaMi-Trop project): a cohort profile.

PurposeWe have established a prospective cohort of 1959 patients with chronic Chagas cardiomyopathy to evaluate if a clinical prediction rule based on ECG, brain natriuretic peptide (BNP) levels, and other biomarkers can be useful in clinical practice. This paper outlines the study and baseline characteristics of the participants.ParticipantsThe study is being conducted in 21 municipalities of the northern part of Minas Gerais State in Brazil, and includes a follow-up of 2 years. The baseline evaluation included collection of sociodemographic information, social determinants of health, health-related behaviours, comorbidities, medicines in use, history of previous treatment for Chagas disease, functional class, quality of life, blood sample collection, and ECG. Patients were mostly female, aged 50-74 years, with low family income and educational level, with known Chagas disease for >10 years; 46% presented with functional class >II. Previous use of benznidazole was reported by 25.2% and permanent use of pacemaker by 6.2%. Almost half of the patients presented with high blood cholesterol and hypertension, and one-third of them had diabetes mellitus. N-terminal of the prohormone BNP (NT-ProBNP) level was >300 pg/mL in 30% of the sample.Findings to dateClinical and laboratory markers predictive of severe and progressive Chagas disease were identified as high NT-ProBNP levels, as well as symptoms of advanced heart failure. These results confirm the important residual morbidity of Chagas disease in the remote areas, thus supporting political decisions that should prioritise in addition to epidemiological surveillance the medical treatment of chronic Chagas cardiomyopathy in the coming years. The São Paulo-Minas Gerais Tropical Medicine Research Center (SaMi-Trop) represents a major challenge for focused research in neglected diseases, with knowledge that can be applied in primary healthcare.Future plansWe will continue following this patients' cohort to provide relevant information about the development and progression of Chagas disease in remotes areas, with social and economic inequalities.Trial registration numberNCT02646943; Pre-results

Síntomas de depresión, ansiedad y estrés en estudiantes del área de la salud e impacto en la calidad de vida

Objective: to evaluate the association between quality of life and presence of symptoms of depression, anxiety, and stress in college students in the health area. Method: cross-sectional study that included 321 students from undergraduate courses in the health area. Quality of life was measured using the World Health Organization scale, abbreviated version, in the physical, psychological, social relations and environment domains, and symptoms were assessed by the depression, anxiety and stress scale. Multivariate analysis was performed using robust linear regression to evaluate the association between quality of life and symptoms. Results: a negative association was observed between the quality of life and depression symptoms in all domains, while anxiety symptoms showed a negative association in the environment domain, and stress symptoms had a negative association in the psychological domain. Symptom severity was unfavorably associated with quality of life, that is, the greater the symptom severity, the lower the mean scores in all domains. Conclusion: symptoms of depression, anxiety, and stress were prevalent and had a negative impact on students’ quality of life, especially in the presence of depressive symptoms. The decrease in scores was significantly associated with the severity of symptoms.Objetivo: evaluar la asociación entre la calidad de vida y la presencia de síntomas de depresión, ansiedad y estrés en estudiantes universitarios del área de la salud. Método: estudio transversal que incluyó a 321 estudiantes de carreras del área de la salud. La calidad de vida se midió mediante la escala de la Organización Mundial de la Salud, versión abreviada, en los dominios físico, psicológico, relaciones sociales y ambiente, y los síntomas se evaluaron por la escala de depresión, ansiedad y estrés. Se realizó un análisis multivariante por medio de regresión lineal robusta para evaluar la asociación entre la calidad de vida y los síntomas presentados. Resultados: se observó una asociación negativa entre la calidad de vida y los síntomas de depresión en todos los dominios, mientras que los síntomas de ansiedad tuvieron una asociación negativa en el dominio ambiente, y los síntomas de estrés tuvieron una asociación negativa en el dominio psicológico. La gravedad de los síntomas se asoció desfavorablemente con la calidad de vida, es decir, cuanto mayor la gravedad de los síntomas, menores las puntuaciones medias en todos los dominios. Conclusión: los síntomas de depresión, ansiedad y estrés fueron prevalentes e impactaron negativamente en la calidad de vida de los estudiantes, especialmente en presencia de síntomas depresivos. Las puntuaciones disminuidas se asociaron significativamente con la gravedad de los síntomas.Objetivo: avaliar a associação entre qualidade de vida e presença de sintomas de depressão, ansiedade e estresse em estudantes universitários da área da saúde. Método: estudo transversal que incluiu 321 estudantes de cursos de graduação da área da saúde.

A diminuição dos escores foi significativamente associada à gravidade dos sintomas

Evaluation of the properties of WHODAS-12 measurements in individuals with Chagas disease in Brazil

Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser–Meyer–Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD

Relação entre Vivência Acadêmica e Ansiedade em Estudantes Universitários

Researches have evaluated the anxiety and college students adaptation to academic life, but few Brazilian studies investigated the relation between these variables. This study aimed to evaluate the student’s degree of academic adaptation and its relation to anxiety and sociodemographic and academic variables. This is a cross-sectional Survey research, part of a multicentric study. Participated 316 students from three institutions: Universidade Federal de São João del-Rei, Universidade Federal de Ouro Preto e Universidade Federal do Triângulo Mineiro. Subjects answered online instruments: Questionário de Vivências Acadêmicas (QVA-r); Escala de Depressão, Ansiedade e Estresse (DASS-21) and sociodemografic/academic questionnaire. Results showed moderate degree of academic adaptation, stronger for the dimensions Carrier, Personal and Interpessonal and moderate levels of anxiety. Multiple regression indicated that higher levels of anxiety were predictor of lower degree of academic adaptation, for Carrier, Study and Institucional. For Carrier, being in a medical course was predictor of lower degree of adaptation. For anxiety, the predictors were being female, being in Nursing course and low age. This research can be considered an advance in this area due to the lack of studies on this issue. Future studies should include others universities and parts of the country.Estudos têm investigado a ansiedade e a adaptação acadêmica em estudantes universitários, mas poucas pesquisas nacionais avaliaram a relação entre estas variáveis. O objetivo deste estudo foi avaliar o grau de adaptação acadêmica dos estudantes e suas relações com ansiedade e variáveis sociodemográficas e acadêmicas. Trata-se de Pesquisa de Levantamento (Survey), de corte transversal, parte de um estudo multicêntrico. Participaram 316 alunos da Universidade Federal de São João del-Rei, Universidade Federal de Ouro Preto e Universidade Federal do Triângulo Mineiro. Foram aplicados os seguintes instrumentos online: Questionário de Vivências Acadêmicas (QVA-r); Escala de Depressão, Ansiedade e Estresse (DASS-21) e Questionário sociodemográfico/acadêmico. Os resultados mostraram grau moderado de adaptação acadêmica, com maiores escores nas dimensões Carreira, Pessoal e Interpessoal e níveis moderados de ansiedade. Na regressão múltipla, maior nível de ansiedade foi preditor de menor adaptação acadêmica, nas dimensões Carreira, Estudo e Institucional. Para a dimensão Carreira, cursar Medicina também foi um fator preditor de menor adaptação. Para ansiedade, os fatores preditores foram: sexo feminino, cursar Enfermagem e ter menor idade. Esta pesquisa pode ser considerada um avanço na área, devido à carência de estudos nesta temática. Estudos futuros deverão incluir outras universidades e regiões do país
