Incidence and impacts of pain in intensive care units: systematic review / Incidência e impactos da dor em unidades de terapia intensiva: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: In Intensive Care Units (ICU), patients are exposed to multiple procedures that can be painful, and health professionals are not always aware of the pain in these patients. Inadequate pain assessment and management, in turn, has been associated with several adverse outcomes, including an increased rate of infection, prolonged mechanical ventilation, hemodynamic disturbances, delirium, and compromised immunity. Thus, this study aimed to summarize the scientific evidence about the incidence and impacts of pain in critically ill patients. CONTENTS: A systematic review of observational studies (Pubmed and EMBASE databases) was performed with predetermined eligibility criteria. In the 32 studies included, it was identified that 10.1% to 61% of patients had pain at rest and 27.4% to 94% during procedures. In addition, there was evidence of improvement in patient outcomes after using validated instruments for pain measurement, including decreased length of ICU stay, duration of mechanical ventilation, mortality, delirium, adverse events, and disease severity. CONCLUSION: Through the present study, it was observed that pain is a common phenomenon in ICU and that its identification and management constitute a realistic goal and depend on the evaluation. Furthermore, pain appears to be associated with worse clinical outcomes. Therefore, efforts must be made to provide comprehensive care for critically ill patients, aiming not only at their survival, but also at alleviating their suffering.

RESUMO JUSTIFICATIVA E OBJETIVOS: Nas Unidades de Terapia Intensiva (UTI) os pacientes são expostos a múltiplos procedimentos que podem ser dolorosos, e nem sempre os profissionais de saúde estão alertas para a dor nesses pacientes. A avaliação e o manejo inadequado da dor, por sua vez, têm sido associados a uma série de resultados adversos, incluindo aumento da taxa de infecção, ventilação mecânica prolongada, distúrbios hemodinâmicos, delírio e imunidade comprometida. Dessa forma, este estudo teve como objetivo sumarizar as evidências científicas acerca da incidência e dos impactos da dor em pacientes críticos. CONTEÚDO: Foi realizada uma revisão sistemática de estudos observacionais (bases de dados Pubmed e EMBASE) com critérios de elegibilidade predeterminados. Nos 32 estudos incluídos, foi identificado que de 10,1% a 61% dos pacientes apresentaram dor em repouso, e de 27,4% a 94% apresentaram dor durante os procedimentos. Além disso, houve evidências de melhora nos resultados dos pacientes após o uso de instrumentos validados para a mensuração da dor, incluindo diminuição do tempo de permanência na UTI, duração da ventilação mecânica, mortalidade, delírio, eventos adversos e gravidade da doença. CONCLUSÃO: Através do presente estudo foi observado que a dor representa um fenômeno comum nas UTI e que a sua identificação e manejo constitui uma meta realista e dependente da avaliação. Além disso, a dor parece estar associada a piores desfechos clínicos. Sendo assim, deve-se voltar esforços para o cuidado integral ao paciente crítico, objetivando não só sua sobrevivência, mas também o alívio do seu sofrimento.

Aflatoxin Occurrence, Food Regulations, Dietary Exposure, and Risk Assessment: A Mini Review from the Malaysian Perspective

@#Aflatoxins are ubiquitous and occur in food. Exposure to aflatoxins seriously impact the health of human and animal. It is concerning especially when aflatoxins are odourless, colourless, and tasteless that hardly be detected through naked eyes. Ingestion of aflatoxin-contaminated food contributes the major route of exposure. The present review is an update on the aflatoxin occurrence in food, aflatoxin regulations in food, and recent risk assessment of aflatoxin exposure in Malaysia. Peanuts and chili were more prone to aflatoxin contamination in Malaysia. The extreme weather experienced in Malaysia and global climatic change may worsen the aflatoxin contamination in food. The regulatory standards for aflatoxins imposed by Malaysia are less stringent than developed countries. The dietary exposure of aflatoxins among Malaysian was relatively high as compared with other Asia countries, ranging from 0.002 to 34.00 ng/kg body weight/day. Nonetheless, Malaysian population had low risk of aflatoxin-related liver cancer, with an estimated liver cancer risk of <1 cancer case/100,000 population/year.

Perfil de paciente geriátrico y factores asociados a mortalidad en población mayor de 80 años con infección por COVID-19: experiencia de un hospital universitario en Bogotá

Objetivo: Caracterizar el perfil del paciente e identificar los factores asociados a mortalidad de población mayor de 80 años hospitalizada por infección por COVID-19, a cargo del Servicio de Geriatría en un hospital universitario de la ciudad de Bogotá. Materiales y métodos: Se llevó a cabo un estudio observacional analítico, basado en la revisión de historias clínicas de una cohorte retrospectiva, en el que se incluyeron pacientes de 80 años o más con infección confirmada por COVID-19, en el período del 1 de marzo de 2020 al 28 de febrero de 2021. La variable dependiente fue mortalidad; las variables independientes, edad, factores clínicos, situación basal y paraclínicos. Resultados: Se identificaron 280 pacientes, con mediana de edad de 84 años, y la mayoría de perfil robusto. El síntoma más frecuente fue tos, seguido por disnea. El 60,3 % de los pacientes presentaron linfopenia, además de elevación de dímero D (> 1000 ug/L), y en la mayoría de los casos se describieron patrones radiológicos típicos de COVID-19. La mortalidad fue del 41,4 %, principalmente asociada a mayor edad, proteína C reactiva elevada, dependencia para actividades básicas de la vida diaria, antecedente de trastorno neurocognitivo mayor, comorbilidad y los pacientes con perfiles dependiente y frágil. Conclusiones: La población geriátrica presenta un alto riesgo de mortalidad por infección por COVID-19. El presente estudio permitió evidenciar qué perfiles de paciente dependientes y frágiles, así como presencia de comorbilidades como trastorno neurocognitivo mayor, enfermedad pulmonar obstructiva crónica y polifarmacia previa al ingreso podrían influir en el desenlace.

Objective: To characterize the geriatric patient profile and identify the mortality-associated factors in a population over 80 years hospitalized with COVID-19 infection in the geriatric ward of a university hospital in the city of Bogotá. Materials and methods: An analytical observational retrospective cohort study based on chart reviews was conducted. The study included patients over 80 years with confirmed COVID-19 infection from March 1, 2020 to February 28, 2021. The dependent variable was mortality and the independent variables were age, clinical factors, baseline characteristics and paraclinical status. Results: Two hundred eighty (280) patients with a median age of 84 years, most of whom were overweight, were identified. The most frequent symptom was cough followed by dyspnea. Out of all patients, 60.3 % presented lymphopenia and elevated D-dimer levels (> 1,000 μg/L), and most of them showed typical imaging patterns of COVID-19. Mortality accounted for 41.4 % and was mainly associated with older age, elevated C-reactive protein, activities of daily living impairment, history of major neurocognitive disorder, comorbidity, and dependent and frail patient profiles. Conclusions: The geriatric population has an increased risk of mortality from COVID-19 infection. The present study showed that dependent and frail patient profiles, as well as the presence of comorbidities such as major neurocognitive disorder, chronic obstructive pulmonary disease and polypharmacy prior to admission, could influence the outcome.

Sistemas de apoio à decisão clínica e desfecho clínico na Atenção Primária à Saúde: uma revisão sistemática / Clinical decision support systems and clinical outcomes in Primary Health Care: a systematic review

Esta revisão sistemática aborda o uso de Sistemas de Suporte à Decisão Clínica (SADC) nos atendimentos realizados na Atenção Primária à Saúde (APS), identificando relações existentes entre o uso dos sistemas e os desfechos clínicos. Foram selecionados trabalhos, estudos em português e inglês, sem restrição ao cenário brasileiro, encontrados em diferentes bases de dados. Os resultados demonstram que os SADC ainda se encontram em estágio de desenvolvimento e refinamento, com aplicação ainda incipiente nas mais diversas patologias e condições clínicas. São raros os ensaios clínicos que tracem os desfechos clínicos primários, levando ao acúmulo de dados apenas sobre desfechos secundários ou compostos, dificultando a avaliação dos sistemas. Há indicativos de relativa eficiência no uso dos SADC para situações de diagnóstico e prevenção, com eficiência limitada na fase de tratamento. Finalmente, não existem dados suficientes para afirmar se os SADC geram desfechos clínicos primários mais favoráveis ou desfavoráveis na APS.

This systematic review addresses the use of Clinical Decision Support Systems (CDSS) in Primary Health Care (PHC), identifying relationships between the use of the Systems and clinical outcomes. The research employed selected studies in Portuguese and English, with no restriction to the Brazilian scenario, found in different databases. Results demonstrate that CDSS are still in the development and refinement stage, and their application is still incipient for the most diverse pathologies and clinical conditions. Clinical trials that trace the primary clinical outcomes are rare, leading to the accumulation of data only on secondary or compound outcomes, making it difficult to evaluate the systems. There are indications of relative efficiency in the use of CDSS for diagnosis and prevention situations, with limited efficiency in the treatment phase. Finally, there is insufficient data to establish whether CDSS generates more favorable or unfavorable primary clinical outcomes in PHC.

ABSTRACT Objective To analyze the association between adherence to antihypertensive treatment and the occurrence of Metabolic Syndrome in hypertensive patients in a primary health care unit. Method Analytical cross-sectional study carried out with 306 hypertensive patients from a Primary Health Care Unit located in the city of Fortaleza-CE. Results Of the study participants, 74.2% were female, mean 61.8 ± 11.9 years old and within the age group of 54 to 69, 77.1% race / brown color, 60.8% with incomplete fundamental level or complete and 70.6% with family income between 1 and 2 minimum wages. Of the evaluated hypertensive patients, 41.5% had Metabolic Syndrome and 76.5% had partial adherence to antihypertensive treatment. In the statistical evaluation of the association between the variables, it was verified that it did not exist (p = 0,149 e p = 0,642). The values regarding adherence to antihypertensive treatment were the same, both in patients with Metabolic Syndrome and in those who did not have this condition. Conclusions and implications for practice High and partial antihypertensive therapy adherence was prevalent. The frequency of Metabolic Syndrome among hypertensive patients under study was high. Therefore, preventive measures for cardiovascular diseases and achievement of therapeutic goals must be implemented continuously. A challenge to be overcome by health professionals and services.

Factors associated with musculoskeletal symptoms in professionals working in sitting position / Fatores associados a sintomas osteomusculares em profissionais que trabalham sentados

ABSTRACT OBJECTIVE To estimate the prevalence of musculoskeletal symptoms and analyze their associated factors in professionals from administrative sectors working predominantly in sitting position. METHODS This is a cross-sectional study with data obtained from 451 workers from a federal public institution in Southern Brazil. The dependent variable was the number of musculoskeletal symptoms in the prior 12 months, measured using the Nordic Musculoskeletal Questionnaire. In the analyses, 19 independent variables were investigated, divided into four categories: sociodemographic, behavioral, occupational and health characteristics. Univariate analysis and multiple Poisson regression with robust variance were performed. The independent variables were inserted into blocks with stepwise backward criterion, considering the value for Wald statistics equal to 0.20. The effect measures were expressed in a relative increase (RI) in the mean value, and the data were analyzed for a 5% significance level. RESULTS The estimated prevalence of musculoskeletal symptoms in the prior 12 months was 90% (confidence interval - 95%CI 87-93). In the final model of regression analysis, the variables female gender (RI = 14.75%), low (RI = 100.02%) and moderate (RI = 64.06%) work ability index, use of medications (RI = 48.06%) and waist circumference at risk (RI = 15.59%) had a significant association with the increase in the mean number of symptoms; schooling with technical education acted as a protective factor, reducing the mean by 36.46%. CONCLUSIONS The high prevalence of musculoskeletal symptoms found and the associated factors indicate the need to propose specific actions and care for this population, such as immediate treatment of symptoms and changes in the organization and work environment, to achieve balance and harmony in the demands of prolonged sitting work and avoid its impact effect of this condition on public health.

RESUMO OBJETIVOS Estimar a prevalência de sintomas osteomusculares e analisar os fatores a eles associados em profissionais de setores administrativos que trabalham predominantemente na postura sentada. MÉTODOS Trata-se de estudo transversal com dados obtidos de 451 trabalhadores de instituição pública federal na região Sul do país. A variável dependente foi o número de sintomas osteomusculares nos últimos 12 meses, aferido utilizando-se o Questionário Nórdico de Sintomas Osteomusculares. Foram investigadas 19 variáveis independentes, divididas em quatro categorias: características sociodemográficas, comportamentais, ocupacionais e de saúde. Foi realizada análise univariada e, na sequência, regressão múltipla de Poisson com variância robusta. As variáveis independentes foram inseridas em blocos com critério backward stepwise, considerando o valor para estatística de Wald igual a 0,20. As medidas de efeito foram expressas em aumento relativo (AR) no valor médio, sendo os dados analisados para um nível de significância de 5%. RESULTADOS A prevalência estimada de sintomas osteomusculares nos últimos 12 meses foi de 90% (intervalo de confiança - IC95% 87-93). No modelo final da análise de regressão, as variáveis sexo feminino (AR = 14,75%), índice de capacidade para o trabalho baixo (AR = 100,02%) e moderado (AR = 64,06%), uso de medicamentos (AR = 48,06%) e circunferência da cintura em risco (AR = 15,59%) tiveram associação significativa com o aumento da média de sintomas; já a escolaridade com ensino técnico atuou como fator de proteção, reduzindo a média em 36,46%. CONCLUSÕES A alta prevalência de sintomas osteomusculares encontrada e os fatores associados indicam a necessidade de propor ações e cuidados específicos para essa população, como tratamento imediato dos sintomas e mudanças na organização e no ambiente laboral, a fim de alcançar equilíbrio e harmonia nas exigências do trabalho sentado prolongado e evitar o impacto dessa condição na saúde pública.

On the use of the E-value for sensitivity analysis in epidemiologic studies / O uso do valor de E para análise de sensibilidade em estudos epidemiológicos / Sobre el uso del E-value para el análisis de sensibilidad en los estudios epidemiológicos

Abstract: This study illustrates the use of a recently developed sensitivity index, the E-value, helpful in strengthening causal inferences in observational epidemiological studies. The E-value aims to determine the minimum required strength of association between an unmeasured confounder and an exposure/outcome to explain the observed association as non-causal. Such parameter is defined as E - v a l u e = R R + R R R R - 1, where RR is the risk ratio between the exposure and the outcome. Our work illustrates the E-value using observational data from a recently published study on the relationship between indicators of prenatal care adequacy and the outcome low birthweight. The E-value ranged between 1.45 and 5.63 according to the category and prenatal care index evaluated, showing the highest value for the "no prenatal care" category of the GINDEX index and the minimum value for "intermediate prenatal care" of the APNCU index. For "inappropriate prenatal care" (all indexes), the E-value ranged between 2.76 (GINDEX) and 4.99 (APNCU). These findings indicate that only strong confounder/low birthweight associations (more than 400% increased risk) would be able to fully explain the prenatal care vs. low birthweight association observed. The E-value is a useful, intuitive sensitivity analysis tool that may help strengthening causal inferences in epidemiological observational studies.

Resumo: O estudo ilustra o uso de um índice recém-desenvolvido para análise de sensibilidade, o valor de E, útil para embasar inferências causais em estudos epidemiológicos observacionais. O valor de E busca identificar a força mínima da associação entre um fator de confusão não medido e uma exposição/desfecho que seria necessária para explicar a associação observada enquanto não causal, definido como valor de E - v a l u e = R R + R R R R - 1, onde RR é a razão de riscos entre a exposição e o desfecho. Aqui, o valor de E é exemplificado através de dados observacionais de um estudo recém-publicado sobre a relação entre indicadores de adequação da assistência pré-natal e o baixo peso ao nascer enquanto desfecho. O valor de E variou entre 1,45 e 5,63, a depender da categoria e do índice de assistência pré-natal avaliado, com o valor máximo para a categoria "sem assistência pré-natal" do índice GINDEX e o mínimo para "assistência pré-natal intermediária" do índice APNCU. Na categoria "assistência pré-natal inadequada" (todos os índices), o valor de E variou entre 2,76 e 4,99 (índices GINDEX e APNCU, respectivamente). Isso indica que apenas associações fortes entre um fator de confusão e baixo peso ao nascer (aumento de risco maior que 400%) seria capaz de explicar plenamente a associação entre assistência pré-natal e baixo peso ao nascer. O valor de E é uma ferramenta útil e intuitiva para análise de sensibilidade, que pode ajudar a fortalecer as inferências causais em estudos epidemiológicos observacionais.

Resumen: El presente estudio ilustra el uso de un índice desarrollado recientemente para el análisis de la sensibilidad, el E-value, útil para el fortalecimiento de las inferencias causales en los estudios epidemiológicos observacionales. El E-value tiene por objetivo identificar la fortaleza de asociación mínima necesaria entre un factor de confusión no calculable y una exposición/resultado que sería necesario para explicar la asociación observada como no-causal, y está definida como E - v a l u e = R R + R R R R - 1, donde RR es la ratio de riesgo entre la exposición y el resultado. Aquí, el E-value es ilustratado con datos observacionales de un estudio recientemente publicado para mostrar la relación entre indicadores de adecuación de cuidado prenatal y el resultado de bajo peso al nacer. El E-value varió entre 1,45 and 5,63, dependiendo de la categoría y el índice cuidado prenatal evaluado, con su valor más alto para la categoría "no cuidado prenatal" del índice GINDEX y el mínimo para el "cuidado prenatal intermedio" del índice APNCU. En la categoría "inapropiado cuidado prenatal" (todos los índices) el E-value varió entre 2,76 y 4,99 (los índices GINDEX y APNCU, respectivamente). Esto indica que solamente un factor de confusión fuerte/asociaciones bajo peso al nacer (incrementaron el riesgo más de un 400%) habría hecho posible explicar completamente la asociación observada cuidado prenatal vs bajo peso al nacer. El E-value es una herramienta de análisis de sensibilidad útil, intuitiva, que puede ayudar a fortalecer las inferencias causales en los estudios epidemiológicos observacionales.

Dietary exposure risk of bisphenol S in vegetables and fruits inHenan Province / 预防医学

Objective@#To monitor the content of bisphenol S ( BPS ) in vegetables and fruits in Henan Province and evaluate the dietary exposure risk of the population, so as to provide the basis for formulating relevant food safety standards.@*Methods@#From 2018 to 2019, 276 samples of vegetables and fruits produced and sold in Henan Province were collected. BPS was determined by isotope dilution ultra performance liquid chromatography triple quadrupole tandem mass spectrometry ( UPLC-MS/MS ) , and the dietary exposure was calculated according to the dietary structure and average body weight of local residents. The risk index of BPS was calculated according to the daily tolerable intake ( TDI ) of bisphenol A ( BPA ). @*Results@#The BPS contents in vegetables and fruits were 0.006-12.600 µg/kg and 0.006-9.380 µg/kg, the medians were 0.053 µg/kg and 0.023 µg/kg, the detection rates were 78.43% and 62.60%, respectively.The detection rate and content of BPS in vegetables were higher than those in fruits ( P<0.05 ). The maximum exposure of BPS from vegetables and fruits was 5.37×10-2 µg/ ( kgbw·d ), and the exposure risk index was 1.07 × 10-3, which was acceptable. @*Conclusions@#BPS was detected from vegetables and fruits in Henan Province. The detection rate and content of BPS in vegetables were higher than those in fruits. The health risk of BPS exposed by vegetables and fruits is small.

Asociación entre desenlaces clínicos y cumplimiento del protocolo de recuperación mejorada después de la cirugía (ERAS) en procedimientos colorrectales: estudio multicéntrico / Association between clinical outcomes and compliance with the Enhanced Recovery After Surgery (ERAS) protocol in colorectal procedures: A multicenter study

Introducción. Los protocolos de recuperación mejorada después de cirugía se han diseñado como una innovación en salud tras demostrarse que la mejora en los dispositivos médicos y la depuración de técnicas alcanzaron la meseta en disminución de complicaciones. Con estas estrategias de la medicina perioperatoria, en cirugía colorrectal se reducen la morbilidad y estancia hospitalaria. El objetivo del estudio fue evaluar si la tasa de adherencia al programa de recuperación mejorada después de la cirugía (ERAS) está asociada con los resultados quirúrgicos. Métodos. Estudio multicéntrico, observacional, retrospectivo de cohorte (2015-2019), en cinco hospitales latinoamericanos certificados por la sociedad ERAS. Se calculó la incidencia de complicaciones quirúrgicas durante el posquirúrgico inmediato (30 días) y la duración de la estancia hospitalaria. Se utilizaron análisis bivariado y regresión logística multivariada para evaluar los factores asociados con la tasa de complicaciones. Resultados. Fueron incluidos en el estudio 648 pacientes en cinco hospitales ERAS, con edad promedio de 61 años y mayor porcentaje de hombres (51 %). El cumplimiento global al protocolo ERAS fue de 75 % y la estancia promedio de 6,2 días (mediana: 4 días). Se tuvo un cumplimiento óptimo del protocolo ERAS (igual o mayor al 80 %) en 23,6 % de los pacientes. Se documentó fuga de la anastomosis en 4 %, complicaciones infecciosas en 8,4 %, íleo en 5,7 %, reingreso en 10,2 % y mortalidad de 1,1 %. El análisis multivariado mostró que los niveles de adherencia óptima al protocolo ERAS reducen significativamente la aparición de complicaciones como fuga de la anastomosis (OR 0,08; IC95% 0,01-0,48; p=0,005) y complicaciones infecciosas (OR 0,17; IC95%0,03-0,76; p=0,046).Discusión. Los resultados sugieren que un cumplimiento del programa ERAS mayor al 80 % se asocia a menor frecuencia de complicaciones en pacientes con cirugía electiva colorrectal

Introduction. Enhanced Recovery After Surgery (ERAS) protocol has been designed as an innovation in health after demonstrating that the improvement in medical devices and the refinement of techniques reached the plateau in reducing complications. With these strategies of perioperative medicine, in colorectal surgery morbidity and hospital stay are reduced. The aim of the study was to evaluate whether the rate of adherence to the ERAS protocol is associated with surgical outcomes.Methods. Multicenter, observational, retrospective cohort study (2015-2019), in five Latin American hospitals certified by the ERAS Society. The incidence of surgical complications during the immediate postoperative period (30 days) and length of hospital stay were calculated. Bivariate analyzes and multivariate logistic regression were used to assess factors associated with complication rates.Results. 648 patients were included in the study in five ERAS hospitals, with an average age of 61 years and a higher percentage of men (51%). Overall compliance with the ERAS protocol was 75% and the average stay was 6.2 days (median: 4 days). There was optimal compliance with the ERAS protocol (equal to or greater than 80%) in 23.6% of the patients. Anastomotic leak was documented in 4%, infectious complications in 8.4%, ileus in 5.7%, readmission in 10.2%, and mortality in 1.1%. Multivariate analysis showed that optimal adherence levels to the ERAS protocol significantly reduce the appearance of complications such as anastomotic leakage (OR 0.08; 95%CI 0.01-0.48; p=0.005) and infectious complications (OR 0.17; 95%CI 0.03-0.76; p=0.046).Discussion. The results suggest that compliance with the ERAS program greater than 80% is associated with a lower frequency of complications in patients with elective colorectal surgery

Pollution status and health effect of dioxins in the atmosphere / 上海预防医学

Dioxin, a persistent organic pollutant, is also a typical environmental endocrine disruptor.With its strong toxicity, it can persist in the environment and be enriched through the food chain.Therefore, it has attracted wide attention in recent years.In this paper, the pollution status of dioxins in the atmosphere is summarized, the risk of respiratory exposure to dioxins is introduced, the possible health effects of human exposure to dioxins are summarized, and suggestions for future control are put forward.In cities and functional areas with high dioxin concentration, long-term inhalation of pollutants has potential risks for people′s health and life span.It is suggested to carry out orderly classification of waste, track and monitor the health status of residents around the waste incinerator, and to establish relevant emission standards and limits, so as to gradually standardize and make the dioxin emission harmless.

Attention should be paid to the exposure risk of patients with chronic wounds on the way to hospital during corona virus disease 2019 epidemic prevention and control / 中华烧伤杂志

Statistics show that 76.74% (4 688) of 6 109 patients with chronic wounds are those over 50 years of age; the proportion of patients with underlying diseases in all age groups above 50 years ranges from 78.25% to 100.00%; among the underlying diseases of chronic wound patients, the top four diseases are diabetes mellitus , cardiovascular and cerebrovascular diseases, hypertension, and respiratory diseases. The above underlying diseases and ages of patients are the susceptibility factors of corona virus disease 2019 released by National Health Commission of China. It is an unavoidable fact that patients with chronic wounds have to go to the hospital for treatment prescribed by the physician. At the same time, we found that there were not a few patients who go far afield because of various reasons when go to the hospital for treatment. During the period of epidemic prevention and control, this kind of "go far afield" style of seeking medical treatment may increase the exposure risk during transportation. Accordingly, we convened 36 wound care clinics in different regions in Shanghai to implement the "Five Measures" to encourage patients with chronic wounds to seek medical treatment proximately. The principle of this operation is that when seeking medical treatment, trying our best to reduce as much as possible the transportation distance for patients with chronic wounds to minimize the exposure risk during the epidemic period and eventually support the epidemic prevention and control campaign.

Analysis of three family clusters of severe fever with thrombocytopenia syndrome by exposure risk matrix / 预防医学

Objective@#To analyze three events of severe fever with thrombocytopenia syndrome （SFTS） among family members by exposure risk matrix, so as to provide reference for SFTS prevention and control.@*Methods @#The field investigation and clinical data of seven confirmed cases with SFTS reported in Linhai from 2014 to 2016 were collected. Exposure risk matrix was used to list the risk of exposure two weeks before the onset, such as the environment, duration of activity and protection, and evaluate the possible routes of transmission. @*Results@#The first event involved three sisters. Two of them had plucked tea together on a hill, and the possibility of infection through tick bites were 60% and 75%, respectively. Another sister was more likely to be infected by ticks in her residence after visiting her sister （no physical contact with the sick sister）, with a possibility of 74%. The second event involved two cases （mother and son）. They were more likely to be infected by ticks in the current residential area, and the possibility were 100% and 80%, respectively. The third event involved two cases （husband and wife）. The wife had 60% possibility of being infected by the ticks on the hill she picked arbutus, and 40% by the ticks in her residence. The husband was most likely to be infected through contacting with body fluids or blood of his wife （44%）, then through the ticks on the hill he picked arbutus （33%）. @*Conclusion@#Among seven cases with SFTS reported in Linhai from 2014 to 2016, six cases have more than 50% possibility of being infected by tick bites; one case has higher possibility of being infected by contacting with body fluids or blood of a patient, but tick bites could not be ruled out.

Clasificación de los desenlaces en los ensayos clínicos / Classification of the outcomes in clinical trials / Classificação dos desenlaces nos ensaios clínicos

El ensayo clínico controlado aleatorizado (ECA) es un experimento planificado, controlado y prospectivo, en el que una o más intervenciones son asignadas a participantes humanos, con el fin de evaluar los efectos sobre los resultados relacionados con la salud, como la eficacia y seguridad de tratamientos, procedimientos o ayudas diagnósticas para diferentes enfermedades. En los ECA se pueden medir diferentes desenlaces, ya sean clínicos, relacionados con el paciente o económicos. Un desenlace es un evento clínico, médico, quirúrgico o de cualquier índole, que busca medir la efectividad y seguridad del tratamiento o intervención que se desea evaluar en un ensayo clínico. La elección de uno o más dependerá de la naturaleza del estudio y de la pregunta que se desea responder. Así mismo, el uso de una amplia gama de ellos tiende a ser más informativo que la medida de uno solo, por lo que es importante reconocer cada uno de estos, para definir su correcta implementación en el ámbito de la investigación. Este estudio tiene como objetivo principal describir los diferentes tipos de desenlaces, los cuales se clasifican en nueve categorías: 1. Eficacia y seguridad; 2. Primario, coprimario, secundario y terciario; 3. Simple y compuesto; 4. Positivo y negativo; 5. Clínicamente significativo y subrogado; 6. Objetivo y subjetivo; 7. Medidas únicas, repetidas y conteos (sucesos); 8. Dicotómico y continuo; y 9. Tiempo fijo y tiempo calendario.

A randomized controlled trial (RCT) is a planned and controlled experiment. It is also a prospective study in which one or more interventions are assigned to human participants in order to assess the effects on health outcomes, such as the efficacy and safety of treatments and interventions for different diseases. Different outcomes, whether clinical, patient-related or economic, can be measured in RCTs. An outcome is a clinical, medical, surgical or any other event that seeks to measure the effectiveness and safety of the treatment or intervention to be evaluated in an RCT. The choice of one or more outcomes depends on the nature of the study and the question to be answered. Likewise, the use of a wide range of outcomes tends to be more informative than the measure of one alone. Therefore, it is important to recognize each of these to define their correct implementation in the field of clinical research. This study aims to describe the different types of outcomes, which are classified into nine categories: 1. Efficacy and safety; 2. Primary, coprimary, secondary and tertiary; 3. Simple and compound; 4. Positive and negative; 5. Clinically significant and subrogated; 6. Objective and subjective; 7. Single, repeated measures and counts (events); 8. Dichotomous and continuous; and 9. Fixed time and calendar time.

O ensaio clínico controlado aleatorizado (ECA) é um experimento planificado, controlado e prospectivo, no qual uma ou mais intervenções são designadas a participantes humanos, com o fim de avaliar os efeitos sobre os resultados relacionados com a saúde, como a eficácia e segurança de tratamentos, procedimentos ou ajudas diagnósticas para diferentes doenças. Nos ECA se podem medir diferentes desenlaces, já sejam clínicos, relacionados com o paciente ou económicos. Um desenlace é um evento clínico, médico, cirúrgico ou de qualquer índole, que busca medir a efetividade e segurança do tratamento ou intervenção que se deseja avaliar num ensaio clínico. A eleição de um ou mais dependerá da natureza do estudo e da pergunta que se deseja responder. Assim mesmo, o uso de una ampla gama deles tende a ser mais informativo que a medida de um só, por isso é importante reconhecer cada um destes, para definir sua correta implementação no âmbito da investigação. Este estudo tem como objetivo principal descrever os diferentes tipos de desenlaces, os quais se classificam em nove categorias: 1. Eficácia e segurança; 2. Primário, co-primário, secundário e terciário; 3. Simples e composto; 4. Positivo e negativo; 5. Clinicamente significativo e sub-rogado; 6. Objetivo e subjetivo; 7. Medidas únicas, repetidas e contagens (acontecimentos); 8. Dicotómico e contínuo; y 9. Tempo fixo e tempo calendário.

Zika: probabilidad de establecimiento de su vector, Aedes aegypti, en Chile / Zika: probability of establishment of its vector, Aedes aegypti, in Chile

Resumen El virus Zika ha despertado una alarma mundial en los últimos años, representando un problema importante para la salud pública. En este estudio evaluamos el riesgo potencial de exposición a virus Zika en Chile, asociado a la probabilidad de establecimiento del vector Aedes aegypti en el país. Se utilizaron técnicas de modelación de nicho para proyectar los requerimientos bioclimáticos del vector (nicho global), identificando las zonas de alta idoneidad para la especie en el país. Luego, se superpuso la distribución potencial del vector en Chile con la densidad de población humana, estimando en forma espacialmente explícita el riesgo asociado a la co-ocurrencia potencial de ambos. Identificamos que existe idoneidad bioclimática para A. aegypti en Chile continental, desde el área tropical del norte hasta regiones templadas, principalmente en zonas costeras. La población potencialmente expuesta podría alcanzar 1,8 millones de personas, con 1,3 millones en nivel medio y 21.000 en niveles altos de riesgo potencial de exposición. Los resultados expuestos aquí muestran que existe una significativa probabilidad de éxito de colonización del vector principal de virus Zika en Chile continental en caso de una introducción. Por lo tanto, la prevención, monitoreo y control se vuelven un tema importante para evitar la llegada de este vector a Chile continental.

The Zika virus has raised world alarm in recent years, representing a major public health problem. In this study we evaluated the potential risk of exposure to Zika virus in Chile, associated with the probability of establishment of the vector Aedes aegypti in the country. Niche modelling techniques were used to project the bioclimatic requirements of the vector (global niches), identifying zones of high suitability for the species within the country. Then, the potential distribution of the vector in Chile was overlapped with the human population density, estimating the risk associated to the potential co-occurrence of both in a spatially explicit manner. We identified bioclimatic suitability for A. aegypti in continental Chile, from the northern tropical area to temperate regions, mainly in coastal zones. The exposed population could reach 1.8 million people, with 1.3 million in a medium level of potential risk and 21,000 in a high level. These results support that there is a significant probability of success for the Zika virus main vector to colonize continental Chile in case of an introduction. Therefore, prevention, monitoring, and control play an important role in avoiding the arrival of this vector to our country.

Avaliação de um protocolo de acolhimento com classificação de risco em relação à capacidade de predizer o desfecho clínico / Assessment of a welcoming protocol with risk classification concerning the ability to envisage the clinical outcome

Os serviços de saúde destinados ao atendimento às urgências e emergências encontram-se, em sua grande maioria, superlotados ocasionando longas filas de espera, o que pode resultar em prejuízo para o atendimento às pessoas com agravos que demandam urgência no atendimento. Diante deste cenário, faz-se necessário uma organização do sistema, a fim de evitar danos aos pacientes que aguardam por atendimento médico. Neste contexto, o Acolhimento com Classificação de Risco traz ao atendimento de urgência e emergência um norteador para classificar os pacientes e realizar atendimento segundo o potencial de risco, atendendo os casos prioritários e não mais por ordem de chegada. Sendo assim, este estudo teve como objetivo avaliar a capacidade de um protocolo de Classificação de Risco adaptado do Ministério da Saúde em predizer o desfecho clínico dos pacientes. O estudo foi realizado em uma unidade de urgência e emergência de um hospital privado do interior paulista, compreendendo os meses de julho de 2014 a junho de 2015, com uma amostra de 1674 prontuários de pacientes que buscaram atendimento clínico. Dos prontuários avaliados, 65% eram de pacientes do sexo feminino, com média de idade de 42,0 anos, a queixa mais frequente estava relacionada ao trato digestório (14,8%). A maioria dos pacientes atendidos foi classificada como pouco urgente (verde) 91,2%, seguido de 8,8% de urgentes (amarelos) e 0,1% classificados como emergentes (vermelho). O tempo de atendimento pela classificação de risco e atendimento médico se mostrou-se mais breve nas classificações com maior prioridade. Na análise dos desfechos, 98,7% receberam alta após atendimento médico, tendo como prevalente a classificação não urgente. Dos pacientes encaminhados à internação 59,1% foram classificados como emergentes/urgentes. Ao relacionarmos a classificação de risco com o escore de alerta precoce (MEWS), observamos uma pontuação superior nos pacientes classificados como emergentes/urgentes, sendo que os pacientes internados obtiveram pontuação maior dos que foram liberados de alta. Os resultados encontrados demonstraram que a classificação de risco foi efetiva em definir a prioridade de atendimento dos pacientes em uma unidade de urgência e emergência

The health services intended to provide urgent and emergency care are mostly overcrowded, which causes long waiting queues and may entail damage to the care of injured people requiring urgent care. Faced with this scenario, there is a need to organize the system, with the purpose of avoiding losses to the patients waiting for medical care. In such a context, the Welcoming with Risk Classification provides the urgent and emergency care with a guiding principle to classify patients and accomplish care actions in line with the potential risk, thereby caring for priority cases, and no longer on a first-come first-served basis. Accordingly, this study was aimed to assess the ability of a Risk Classification protocol adapted from the Ministry of Health to envisage the clinical outcome of the patients. The study was held in an urgent and emergency unit in a private hospital in the countryside of São Paulo, between the months of July 2014 and June 2015, with a sample of 1674 medical charts of the patients that sought clinical care. Of the assessed medical charts, 65% belonged to female patients, with an average age of 42.0 years, where the most frequent complaint was related to the digestive tract (14.8%). Most of patients served were classified as less urgent (green), 91.2%, followed by 8.8% classified as urgent (yellow) and 0.1% classified as emergency (red). The service time by the risk classification and medical care has proved to be shorter in the classifications with greater priority. Upon analyzing the outcomes, 98.7% were discharged after medical care, where the non-urgent classification was prevalent. Of the patients referred for hospitalization, 59.1% were classified as emergency/urgent. When relating the risk classification with the early warning score (MEWS), we noted a higher score in the patients classified as emergency/urgent, and the hospitalized patients have reached scores higher than those who were discharged. The results found have shown that the risk classification was effective in defining the priority of care of patients in an urgent and emergency unit

Pesticide Application, Dermal Exposure Risk And Factors Influenced Distribution On Different Body Parts Among Agriculture Workers

@#Agriculture sector accounts significant numbers of injuries and fatalities in the workplace particularly related to pesticide management. Among three main pathways of pesticide exposure, dermal contact is the most common route, which exposure usually occurs during pesticide mixing/loading, application, harvesting and other farming activities. This review aims to present and discuss several vital components of pesticide dermal exposure among agriculture workers, as well as pesticide application in agriculture sector in Malaysia involving different commodity agriculture sub-sectors. Pesticide exposure was discussed from perspective of three pesticide management activities (i.e. preparation, application and cleaning) that contribute to the risk of exposure through three routes (i.e. emission, deposition, transfer). Moreover, this paper also discussed pesticide dermal exposure risk assessment methods which can be defined into exposure assessment and effect assessment. The exposure rate was affected by various factors such as application equipment, application rate and duration, type of pesticide formulation, pesticide management stage, usage of personal protective equipment, training and aptitude of the applicator as well as environmental factors (i.e. temperature, humidity, wind speed and direction). The factors mention earlier have been used to explain the exposure distribution over different parts of the body and support the fact that pesticide type was not a major factor in total exposure.

Distúrbio de voz: definição de caso em estudos epidemiológicos / Voice disorder: case definition in epidemiological studies / Trastorno de la voz: definición de caso en estudios epidemiológicos

A definição de caso é de crucial importância em estudos epidemiológicos. Uma boa definição de caso deve identificar todos aqueles que têm o problema e excluir os que não o têm, tendo, portanto, boa sensibilidade e especificidade. Distúrbio de voz é um quadro de difícil mensuração por ser resultado de complexa interação fatores biológicos, psíquicos e sociais. Por ser manifestação dinâmica e funcional, a doença não pode ser definida em oposição à saúde, e sim, como parte de um mesmo processo. Este estudo teve o objetivo de analisar a definição do conceito de distúrbio de voz por meio da presença de alterações nos exames perceptivo-auditivo da voz e perceptivo-visual da laringe, da autorreferência de sintomas vocais e do impacto da desvantagem do distúrbio de voz para o sujeito. A pesquisa foi realizada para definição de caso em estudo caso-controle, sendo a população composta por professoras da rede municipal de São Paulo. Todas se submeteram à avaliação de voz, de laringe, e responderam questionários Condição de Produção Vocal do Professor (CPV-P) e Índice de Desvantagem Vocal (IDV). Os resultados apontam que a amostra dividiu-se, de forma similar, em quatro grupos diferenciados em relação ao distúrbio de voz, pela presença de alteração nas avaliações fonoaudiológica e otorrinolaringológica, pela referência de sintomas, e em função do impacto causado pelo distúrbio na vida social e profissional.

Case definition is of crucial importance in epidemiological studies. A good case definition must identify all individuals that have the problem and remove all individuals who don't have it, therefore having good sensitivity and specificity. Voice disorder is a condition difficult to measure as a result from a complex interaction of biological, psychic and social factors. As a dynamic and functional expression, the disease cannot be defined in opposition to health, but as a part of the same process. This study aimed to analyze the definition of voice disorder concept through the presence of changes in the perceptual auditory analysis of voice and visual perceptual of larynx, as well as for tests concerning the self-reference of vocal symptoms and the impact of the voice disorder handicap for the individual. The research was conducted for case definition in case-control study, with the population composed by teachers from the municipal network of São Paulo. All individuals were submitted to voice and laryngeal assessments, and they answered the Condition of Vocal Production - Teacher (CPV-P) and Voice Handicap Index (VHI) questionnaires. The results indicate that the sample was divided, in a similar way, in four different groups with respect to voice disorder both by the presence of changes in the speech language therapy and otorhinolaryngological assessments, by the reference of symptoms, and as according to the impact caused by a disorder in the social and professional life.

Population attributable fraction: planning of diseases prevention actions in Brazil / Fração atribuível populacional: planejamento de ações de prevenção de doenças no Brasil

ABSTRACT Epidemiology is the study of occurrence, distribution and determinants of health-related events, including the application of that knowledge to the prevention and control of health problems. However, epidemiological studies, in most cases, have limited their research questions to determinants of health outcomes. Research related to the application of knowledge for prevention and control of diseases have been neglected. In this comment, we present a description of how population attributable fraction estimates can provide important elements for planning of prevention and control of diseases in Brazil.

RESUMO Epidemiologia é o estudo da ocorrência, distribuição e determinantes de eventos relacionados à saúde da população, incluindo a aplicação desse conhecimento para a prevenção e o controle dos problemas de saúde. Entretanto, estudos epidemiológicos, na maioria das vezes, têm limitado suas perguntas de pesquisa aos fatores determinantes de desfechos em saúde. Pesquisas relacionadas à aplicação do conhecimento para ações de prevenção e controle de doenças têm sido negligenciadas. Nesse comentário, apresentamos uma descrição de como as estimativas de fração atribuível populacional podem fornecer importantes elementos para planejamento de ações de prevenção e controle de doenças no Brasil.

A Study on the Prevalence of Indoor Mycoflora in Air Conditioned Buses.

Aim: To study the presence of indoor mycoflora in A/c Buses to know the commuters risk of exposure to fungal spores. Place and Duration: Chennai Mofussil Bus Terminus (CMBT), Koyambedu, Chennai, India. Study was conducted from November 2011 to April 2012. Methodology: Airborne fungi from 50 A/c buses were studied using Reuter Centrifugal Sampler (Biotest, Germany), fungi from the surfaces of air vents through swab sample and bus seats by rubbing sterile petridishes on the seats. Sabourauds Dextrose Agar (SDA) was used for the isolation of fungi from different buses. The collected data were statistically analyzed. Results: A total of 38 species classified in 21 genera were recorded. Among which, Zygomycetes was represented by 4 species, Ascomycetes and Coelomycetes by single species each and the remaining belongs to Hyphomycetes. The genus, Aspergillus was represented by maximum number of species (11 species) followed by Penicillium (5 species). A total average of 713 CFU/m3 of air was recorded within the buses. Aspergillus niger was the first dominant fungi in the order of dominance followed by Chrysonilia sitophila, Alternaria alternata and Aspergillus flavus in that order. From the surface of bus seats, Aspergillus niger, A. flavus, Rhizopus stolonifer and A. japonicus were recorded as dominant. However, different mycofloral composition was recorded from air vents. Cladosporium chlorocephalum and Curvularia lunata dominated the surface of air vents. Conclusion: The study demonstrates the presence of potential fungal species which pose exposure risk to the immune compromised commuters.
