ABSTRACT BACKGROUND: Stroke is a major cause of death and functional disability worldwide. Knowledge of the associated factors is essential for defining education, management, and healthcare strategies. OBJECTIVE: To analyze the association between arrival time at a neurology referral hospital (ATRH) and functional disability in patients with ischemic stroke 90 days after the event. DESIGN AND SETTING: Prospective cohort study conducted at a public institution of higher education in Brazil. METHODS: This study included 241 people aged ≥ 18 years who presented ischemic stroke. The exclusion criteria were death, inability to communicate without companions who could answer the research questions, and > 10 days since ictus. Disability was assessed using the Rankin score (mR). Variables for which associations showed a P value ≤ 0.20 in bivariate analysis were tested as modifiers between ATRH and disability. Significant interaction terms were used for multivariate analysis. Multivariate logistic regression analysis was performed with all variables, arriving at the complete model and adjusted beta measures. The confounding variables were included in the robust logistic regression model, and Akaike’s Information Criterion was adopted to choose the final model. The Poisson model assumes a statistical significance of 5% and risk correction. RESULTS: Most participants (56.0%) arrived at the hospital within 4.5 hours of symptom onset, and 51.7% presented with mRs of 3 to 5 after 90 days of ictus. In the multivariate model, ATRH ≥ 4.5 hours and females were associated with more significant disability. CONCLUSIONS: Arrival at the referral hospital 4.5 hours after the onset of symptoms or wake-up stroke was an independent predictor of a high degree of functional disability.

RESUMO Objetivo: Analisar a associação entre tempo de chegada a hospital de referência e mortalidade de pessoas com Acidente Vascular Cerebral isquêmico. Método: Foram utilizadas estatísticas descritivas e inferenciais. Variáveis modificadoras e confundidoras entre tempo de chegada e mortalidade foram verificadas na análise multivariada. O Critério de Informação de Akaike foi utilizado para escolha do modelo. Adotou-se significância estatística de 5% e correção de risco pelo Modelo de Poisson. Resultados: A maioria dos participantes chegou em até 4,5 horas do início dos sintomas ou wake up stroke ao hospital de referência e 19,4% morreram. A pontuação da National Institute of Health Stroke Scale foi um modificador. No modelo multivariado estratificado por pontuação da escala ≥14, o tempo de chegada >4,5h estava associado a menor mortalidade; e idade ≥60 anos e ter Fibrilação Atrial, a maior mortalidade. No modelo estratificado por pontuação ≤13, Rankin prévio ≥3 e ter fibrilação atrial foram preditores de mortalidade. Conclusão: A relação entre tempo de chegada e mortalidade até 90 dias foi modificada pela pontuação da National Institute of Health Stroke Scale. Rankin prévio ≥3, fibrilação atrial, tempo de chegada ≤4,5h e idade ≥60 anos contribuíram para maior mortalidade.

ABSTRACT Objective: To analyze the association between time of arrival at a reference hospital and mortality of people with ischemic stroke. Method: Descriptive and inferential statistics were used. Modifying and confounding variables between time of arrival and mortality were observed in the multivariate analysis. The Akaike Information Criterion was used to choose the model. Statistical significance of 5% and risk correction using the Poisson Model were adopted. Results: Most participants arrived within 4.5 hours of symptom onset or wake up stroke to the referral hospital and 19.4% died. The score of the National Institute of Health Stroke Scale was a modifier. In the multivariate model stratified by scale score ≥14, arrival time >4.5h was associated with lower mortality; and age ≥60 years and having Atrial Fibrillation, to higher mortality. In the model stratified by score ≤13, previous Rankin ≥3, and presence of atrial fibrillation were predictors of mortality. Conclusion: The relationship between time of arrival and mortality up to 90 days was modified by the National Institute of Health Stroke Scale. Prior Rankin ≥3, atrial fibrillation, time to arrival ≤4.5h, and age ≥60 years contributed to higher mortality.

Abstract This study aimed to identify clinical and laboratory variables that could help predict the negative outcome in cattle affected by gastrointestinal emergencies. A retrospective cohort study was carried out using multivariate logistic regression analysis based on data collected from the clinical records of cattle hospitalized at the Garanhuns Bovine Clinic, UFRPE campus. One hundred and twenty-two cattle met the inclusion criteria established for the study. Among the clinical variables, heart rate (HR) and abdominal distension are associated with the outcome in animals with right displaced abomasum (RDA), and anorexia and 10% dehydration in animals with an obstructive intestinal disorder. Among the laboratory variables, plasma fibrinogen (PF) and total leukocyte count were associated with the outcome in animals with RDA, while PF and plasma L-lactate were associated with animals with an obstructive intestinal disorder. HR and the total leukocyte count remained in the final model of the regression adjusted for animals with RDA. On the other hand, plasma L-lactate and PF remained in the final model in the adjusted model for animals with an obstructive intestinal disorder. Cattle with RDA and HR higher than 90 bpm present an increased chance of having a negative outcome whereas cattle with obstructive intestinal disorder and plasma L-lactate higher than 1.84 mmol/L or PF higher than 850 mg/dL have a higher chance of not survive. Therefore, clinical and laboratory variables such as HR, fibrinogen, and plasma L-lactate are useful to predict the negative outcome in cattle with gastrointestinal emergencies, especially RDA and obstructive intestinal disorders.

Resumo Este estudo teve como objetivo identificar variáveis clínicas e laboratoriais que pudessem ajudar a predizer o desfecho negativo em bovinos acometidos por emergências gastrointestinais. Foi realizado um estudo de coorte retrospectivo por meio de análise de regressão logística multivariada com base em dados coletados dos prontuários de bovinos internados na Clínica de Bovinos de Garanhuns, campus da UFRPE. Cento e vinte e dois bovinos atenderam aos critérios de inclusão estabelecidos para o estudo. Dentre as variáveis clínicas, a frequência cardíaca e a distensão abdominal estão associadas ao desfecho em animais com deslocamento de abomaso à direita (DAD), e anorexia e 10% de desidratação em animais com distúrbio intestinal obstrutivo. Entre as variáveis laboratoriais, o fibrinogênio plasmáticao (FP) e a contagem total de leucócitos foram associados ao desfecho em animais com DAD, enquanto o FP e o L-lactato plasmático foram associados a animais com distúrbio intestinal obstrutivo. A frequência cardíaca (FC) e a contagem total de leucócitos permaneceram no modelo final da regressão ajustada para animais com DAD. Por outro lado, o L-lactato plasmático e o FP permaneceram no modelo final ajustado para animais com distúrbio intestinal obstrutivo. Bovinos com DAD e FC maior que 90 bpm apresentam maior chance de ter um desfecho negativo, enquanto bovinos com distúrbio intestinal obstrutivo e L-lactato plasmático maior que 1,84 mmol/L ou FP maior que 850 mg/dL têm maior chance de não sobreviver. Portanto, variáveis clínicas e laboratoriais como FC, FP e L-lactato plasmático são úteis para predizer o desfecho negativo em bovinos com doenças emergências gastrointestinais, especialmente DAD e distúrbios intestinais obstrutivos.

Abstract The study aimed to characterize women that attended prenatal care in Brazil according to ethnicity/skin color and sociodemographic variables and to verify the association between the indicators of the prenatal care process and the women’s ethnicity/skin color. This was a population based, cross-sectional study carried out with data from the National Health Survey of 2013. A bivariate analysis was performed using the multilevel logistic regression model, estimating the odds ratio and the respective 95% confidence intervals to test the association between the indicators of the adequate prenatal care process and the women’s ethnicity/skin color. The findings showed that black women have a lower chance of starting prenatal care before 12 weeks of gestation, having 6 or more consultations, performing the HIV test, performing the VDRL exam or receiving advice related to care during gestation and childbirth. Inequalities were identified in the healthcare of Brazilian women during prenatal care, related to ethnicity/skin color and other sociodemographic characteristics. It was concluded that being of black ethnicity and living in a socially disadvantaged area entails disadvantages for women regarding access to a prenatal care considered to be adequate according to the criteria established by the Brazilian Ministry of Health.

Resumo Esta investigação teve como objetivo caracterizar as mulheres que realizaram o pré-natal no Brasil segundo raça/cor e variáveis sociodemográficas e verificar associação entre os indicadores de processo do cuidado no pré-natal e a raça/cor das mulheres. Estudo transversal de base populacional empreendido com dados da Pesquisa Nacional de Saúde de 2013. Realizou-se análise bivariada mediante modelo de regressão logística multinível, estimando-se as odds ratio para medir a associação entre os indicadores de processo do cuidado pré-natal adequado e raça/cor das mulheres e verificando os respectivos intervalos de confiança de 95%. Os achados evidenciaram que mulheres negras possuem menor chance de iniciar o pré-natal antes das 12 semanas de gestação, ter seis ou mais consultas, realizar teste de HIV, exame VDRL e receber orientações referentes aos cuidados na gestação e parto. Identificamos desigualdades na atenção à saúde das mulheres brasileiras atendidas no pré-natal relacionadas à raça/cor e a outras características sociodemográficas. Conclui-se que ser negra e ocupar lugares sociais desfavoráveis acarretam desvantagens para as mulheres quanto ao acesso a um pré-natal considerado adequado segundo os critérios estabelecidos pelo Ministério da Saúde do Brasil.

Abstract: En | Text: En | PDF: En

Objective: Positron emission tomography (PET) allows in vivo evaluation of molecular targets in neurodegenerative diseases, such as Alzheimer’s disease. Mild cognitive impairment is an intermediate stage between normal cognition and Alzheimer-type dementia. In vivo fibrillar amyloid-beta can be detected in PET using [11C]-labeled Pittsburgh compound B (11C-PiB). In contrast, [18F]fluoro-2-deoxy-d-glucose (18F-FDG) is a neurodegeneration biomarker used to evaluate cerebral glucose metabolism, indicating neuronal injury and synaptic dysfunction. In addition, early cerebral uptake of amyloid-PET tracers can determine regional cerebral blood flow. The present study compared early-phase 11C-PiB and 18F-FDG in older adults without cognitive impairment, amnestic mild cognitive impairment, and clinical diagnosis of probable Alzheimer’s disease. Methods: We selected 90 older adults, clinically classified as healthy controls, with amnestic mild cognitive impairment, or with probable Alzheimer’s disease, who underwent an 18F-FDG PET, early-phase 11C-PiB PET and magnetic resonance imaging. All participants were also classified as amyloid-positive or -negative in late-phase 11C-PiB. The data were analyzed using statistical parametric mapping. Results: We found that the probable Alzheimer’s disease and amnestic mild cognitive impairment group had lower early-phase 11C-PiB uptake in limbic structures than 18F-FDG uptake. The images showed significant interactions between amyloid-beta status (negative or positive). However, early-phase 11C-PiB appears to provide different information from 18F-FDG about neurodegeneration. Conclusions: Our study suggests that early-phase 11C-PiB uptake correlates with 18F-FDG, irrespective of the particular amyloid-beta status. In addition, we observed distinct regional distribution patterns between both biomarkers, reinforcing the need for more robust studies to investigate the real clinical value of early-phase amyloid-PET imaging.

Objectives: Past suicide attempt (SA) is one of the most important risk factors for suicide death. An ideation-to-action framework posits that impulsivity, potentially traumatic events, and mental disorders also play a role in increasing suicide risk. This study aimed to assess the association between trait impulsivity, lifetime exposure to trauma, and post-traumatic stress disorder (PTSD) with SA in a sample of Brazilian college students. Methods: A total of 2,137 participants filled self-reported questionnaires consisting of a sociodemographic and clinical questionnaire, Trauma History Questionnaire, Post-Traumatic Stress Disorder Checklist – Civilian version, and Barratt Impulsiveness Scale. Results: Our findings suggest that trait impulsivity may be interpreted as exerting a distal effect on SA, even in the presence of other variables – such as trauma history, psychological neglect, and PTSD – which also increase the odds of SA. High and medium levels of impulsivity, history of trauma, and PTSD increased the likelihood of SA. Conclusions: Intervention strategies to prevent SA may target trait impulsivity and exposure to traumatic experiences.

Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Objectives To assess the frequency of subclinical cardiotoxicity and to compare global longitudinal strain and EF measurements during the clinical course of patients undergoing chemotherapy for breast cancer. Methods This was an observational prospective study of 78 adult women who underwent serial echocardiograms (baseline and 1, 3, and 6 months after the beginning of chemotherapy), to evaluate biplane and 3D EF and global longitudinal strain. Cardiotoxicity and subclinical dysfunction were defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. Statistical significance was set at p < 0.05. Results The mean age of the patients was 50.1 ± 11.48 years. The frequency of subclinical cardiotoxicity (defined by global longitudinal strain) was 14.9% after 30 days of chemotherapy, 16.7% after 3 months, and 19.7% after 6 months, compared to 4.5%, 3%, and 6.6%, respectively, when clinical cardiotoxicity was determined according to EF. The group that developed subclinical cardiotoxicity by 30 days (group A) had a higher frequency of clinical cardiotoxicity at 3 months (p=0.028) and a lower mean biplane EF after 30 days (p= 0.036) than the group that showed no evidence of subclinical cardiotoxicity (group B). Conclusion Subclinical cardiotoxicity was frequent and began early, being associated with a drop in EF during the clinical course.

Abstract In this study, we aimed to assess the spatial variability of microclimate inside a closed compost-bedded pack barn (CBP) with a negative ventilation system during summer and winter. The research was carried out in a CBP located in the Zona da Mata region, Minas Gerais, Brazil. For each of the stations analyzed, the following environmental mean variables observed inside a CBP were measured: air dry-bulb temperature (tdb), air relative humidity (RH), and windspeed, Temperature-Humidity index, and specific enthalpy. The kriging maps showed that the most critical housing conditions in the thermal environment were found, mainly, from the central part of the CBP, close to the exhaust fans. The analyses also pointed out that the system presented temperature gradients along the length, up to 3°C. During the summer afternoon, the entire region of the CBP was in a discomfort situation (tdb>26°C; RH>75%). During the winter, the measured environmental data remained within the comfort zone throughout the facility. However, probably due to the lack of thermal insulation of the material used to close the sides of the CBP, it did not allow spatial thermal uniformity for both seasons. It was also inefficient to keep the animals within the comfort zone for lactating cattle during the critical summer period.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

ABSTRACT Food frequency questionnaires are research tools widely used at the population level to assess food intake, especially in childhood. The objectives of this study were to develop and determine the relative validity of the Food Frequency Questionnaire (FFQ) for the evaluation of food intake among Ecuadorian schoolchildren. One hundred children from rural coastal areas of Ecuador, aged 6 to 8 years, were included. Mothers completed 1 FFQ frequency and two 24-hour recalls (R24h gold standard). Pearson correlation, weighted Kappa and the Bland Altman method were used to assess validity. Linear regression models were used including R24h as a dependent variable and FFQ as an independent variable to derive calibration factors. The Pearson coefficients ranged between -0.03 and 0.24. The Kappa values varied between -0.05 and 0.24, the Bland-Altman plots were between the limits near the midline and the calibration factors ranged from -0.01 to 0.16. The FFQ was considered appropriate to evaluate energy and nutrient consumption, however, due to its weak to moderate agreement this must be corrected using calibration values. This FFQ is a useful tool for evaluating diet and the relationship between diet and disease in this population group.

RESUMEN Los Cuestionarios de Frecuencia de Consumo de Alimentos son herramientas de investigación ampliamente utilizadas a nivel poblacional para evaluar la ingesta alimentaria, especialmente en niños. Los objetivos de este estudio fueron construir y determinar la validez relativa del Cuestionario de Frecuencia de Consumo de Alimentos (CFCA) para la evaluación de la ingesta entre niños ecuatorianos en edad escolar. Fueron incluidos 100 niños entre 6 y 8 años de edad de zonas costeras rurales del Ecuador. Las madres completaron 1 CFCA y 2 Recordatorios de 24 horas (R24h, estándar oro). Se utilizaron correlaciones de Pearson, Kappa ponderado y el método de Bland Altman para evaluar su validez. Se aplicaron modelos de regresión lineal incluyendo el R24h como variable dependiente y CFCA como variable independiente para derivar factores de calibración. Los coeficientes de Pearson oscilaron entre -0,03 y 0,24. Los valores de Kappa variaron entre -0,05 y 0,24, los gráficos de Bland-Altman se encuentran entre los límites cerca de la línea media y los factores de calibración oscilaron entre -0,01 a 0,16. Después de aplicar los factores de calibración, las ingestas medias de energía, macro y micro nutrientes fueron similares a las obtenidas en el R24h. El CFCA fue considerado apropiado para evaluar consumo de energía y nutrientes, sin embargo, debido a su concordancia débil a moderada este debe ser corregido mediante los valores de calibración. Asimismo, este CFCA es una herramienta útil para la evaluación de la dieta y la relación entre la dieta y la enfermedad en este grupo poblacional.

Este trabalho é uma reflexão teórica acerca do fenômeno “ficar” praticado pelos adolescentes. Parte de alguns frag-mentos e vinhetas clínicas para discutir uma forma discursiva que reflete um modo instável de investimento libidinal e se apresenta como uma “nova forma de relacionamento”. Tomando como referência a psicanálise, define o “ficar”, primeiro como um tempo lógico cuja característica essencial é uma articulação entre o imaginário social e a ordem simbólica, que produz um achatamento do desejo no primeiro, constituindo um “não lugar” ao mesmo tempo discursivo e existencial.

Resumos This paper is a theoretical reflection on the “hook up” (“ficar” in Portuguese) phenomenon practiced by Brazilian adolescents. It is based on some clinical fragments and vignettes to discuss a discursive form that reflects an unstable mode of libidinal investment that presents itself as a “new form of relationship”. Using psychoanalysis as a reference, this study defines “hook up” primarily as a logical time which essential feature is a connection between the social imaginary and the symbolic order, which leads to a reduction of the desire in the former one, constituting both a discursive and an existential “non-place” at the same time.

El presente artículo es una reflexión teórica sobre el fenómeno de “ligar” (ficar, originalmente en portugués) practicado por los adolescentes brasileños. Parte de algunos fragmentos y viñetas clínicas para discutir una forma de discurso que refleja una manera inestable de inversión libidinal y que se presenta como una “nueva forma de relación”. Considerando el psicoanálisis como referencia, se define el “ligar”, primero, como un tiempo lógico cuya característica esencial es una articulación entre el imaginario social y el orden simbólico, que produce un aplanamiento del deseo en el primero, constituyendo de esta forma un “no lugar” discursivo y existencial al mismo tiempo.

Ce travail est une réflexion théorique sur le phénomène du “ficar” (sortir/coucher ensemble) pratiqué par les adolescents brésiliens. Il se base sur des fragments et des vignettes cliniques pour discuter une forme discursive reflétant un mode instable d’investissement libidinal qui se présente comme une “nouvelle forme de relation”. En prenant comme référence la psychanalyse, il définit “ficar” d’abord comme un temps logique dont le trait essentiel est le rapport entre l’imaginaire social et l’ordre symbolique, ce qui produit un aplatissement du désir chez le premier, constituant à la fois un “non-lieu” discursif et existentiel.

Abstract Objective: The objective of the study was to describe the myocardial infarction treatment network and compare in-hospital mortality in patients undergoing either primary angioplasty or pharmacoinvasive strategy in Mexico City and a broad metropolitan area. Methods: Cohort study including patients with ST-elevation myocardial infarction. We recorded demographic and clinical data, laboratory tests and in-hospital mortality in patients that underwent primary angioplasty and pharmacoinvasive strategy. Kaplan-Meier analysis was used to assess mortality and Cox-regression assessed mortality risk factors. Results: Three hundred forty patients from a network of 60 hospitals and 9 states were analyzed. Of the total population, 166 were treated with pharmacoinvasive strategy and 174 with primary angioplasty. Door to thrombolytic time was 54 min and door to wire crossing time was 72.5 min; no differences in total ischemia time were demonstrated. No differences for in-hospital mortality (6.3% vs. 5.4%, p = 0.49) were found when comparing pharmacoinvasive and primary angioplasty groups. The main predictors for in-hospital mortality were: glucose > 180 mg/dl (HR 3.73), total ischemia time > 420 min (HR 3.18), heart rate > 90 bpm (HR 5.46), Killip and Kimball > II (HR 11.03), and left ventricle ejection fraction < 40% (HR 3.21). Conclusions: This myocardial infarction network covers a large area and constitutes one of the biggest in the world. There were no differences regarding in-hospital mortality between pharmacoinvasive strategy and primary angioplasty. Pharmacoinvasive strategy is an effective and safe option for prompt reperfusion in Mexico.

Resumen Objetivo: Describir la red de atención de infarto agudo de miocardio y comparar los desenlaces intrahospitalarios en pacientes tratados con angioplastía coronaria o estrategia farmacoinvasiva en la Ciudad de México y su área metropolitana. Métodos: Estudio de cohorte que incluyó pacientes con infarto agudo de miocardio con elevación del segmento ST. Se recabaron datos demográficos y clínicos, así como estudios de laboratorio y mortalidad intrahospitalaria en los pacientes que fueron tratados con angioplastía coronaria o estrategia farmacoinvasiva. Se realizó un análisis de Kaplan-Meier para describir la mortalidad y un modelo de regresión de Cox para evaluar los factores asociados a mortalidad. Resultados: Se analizaron 340 pacientes provenientes de una red compuesta por 60 hospitales. Del total de la población, 166 fueron tratados con estrategia farmacoinvasiva y 174 con angioplastía primaria. El tiempo puerta-aguja fue 54 min. y el tiempo puerta-dispositivo de 72.5 min.; no se encontraron diferencias en el tiempo total de isquemia. Además, no existieron diferencias en la mortalidad intrahospitalaria (6.3% vs. 5.4%, p = 0.49) al comparar la estrategia farmacoinvasiva y la angioplastía primaria. Los principales predictores de mortalidad intrahospitalaria fueron: glucosa > 180 mg/dl (HR 3.73), tiempo total de isquemia > 420 min. (HR 3.18), frecuencia cardiaca > 90 lpm (HR 5.46), Killip and Kimball > II (HR 11.03) y fracción de eyección < 40% (HR 3.21). Conclusiones: En esta red de atención al infarto agudo de miocardio no se encontraron diferencias en la mortalidad intrahospitalaria entre la estrategia farmacoinvasiva y la angioplastia primaria. La estrategia farmacoinvasiva puede ser una alternativa efectiva y segura para lograr reperfusión adecuada en México.
