ABSTRACT

Objetivo: aplicar a modelagem logística da primeira onda da COVID-19, com índice nos países com 20 maiores Produto Interno Bruto (PIB). Métodos: foi utilizada a modelagem matemática de crescimento logístico, considerando os seguintes parâmetros: número cumulativo de casos (C), tamanho final da epidemia na onda única de um surto (K), taxa intrínseca de crescimento (y) e tempo de inflexão (τ). Resultados: o Brasil apresentou maior número de casos e mortalidade, e os Estados Unidos da América (EUA) maior número de casos absolutos. A Coreia do Sul evidenciou o menor ponto de inflexão de 15,3 dias, enquanto o maior foi da Indonésia, com 213,9 dias. Na análise entre o ponto de inflexão e casos acumulados (/100 mil habitantes), observou-se correlação positiva moderada significativa (r=0,629 e p=0,003); (r=0,532 e p=0,016). Conclusão: o reconhecimento do comportamento de uma epidemia por meio da modelagem matemática torna possível determinar a propagação de uma epidemia, visto que, com a possibilidade de captar a dinâmica de uma epidemia, torna-se possível prever a necessidade de medidas públicas antecipadas e, consequentemente, diminuição da mortalidade global.


Objective: to apply logistic modeling of the first wave of COVID-19 in countries with the 20 highest Gross Domestic Product (GDP). Methods: logistic growth mathematical modeling was used, considering the following parameters: cumulative number of cases (C), the final size of the epidemic in the single wave of an outbreak (K), intrinsic growth rate (y), and inflection time (τ). Results: Brazil showed the highest number of cases and mortality, and the United States of America (USA) had the highest number of absolute cases. South Korea showed the lowest inflection point of 15.3 days, while the highest infection point was Indonesia, with 213.9 days. In the analysis between the inflection point and cumulative cases (/100,000 population), a moderate significant positive correlation was observed (r=0.629 and p=0.003); (r=0.532 and p=0.016). Conclusion: the recognition of the behavior of an epidemic through mathematical modeling makes it possible to determine the spread of an epidemic, since, with the possibility of capturing the dynamics of an epidemic, it becomes possible to predict the need for anticipated public measures and, consequently, decrease in overall mortality.

ABSTRACT

Introducción: La malaria es una de las enfermedades infecciosas más importantes y para tratarla además de medicamentos, la población emplea plantas medicinales. El objetivo fue establecer los factores asociados a malaria y las plantas empleadas para su tratamiento en habitantes de Corozal. Método: Se aplicó una encuesta con preguntas sociodemográficas, de la vivienda, de conocimiento y de actitudes y las plantas medicinales empleadas para tratarla. Resultados: El 48% emplean plantas medicinales solas o con medicamentos, siendo el Gliricidia sepium (matarratón) y el Acmella oppositifolia (yuyo) las plantas más empleadas. En el 48% de las casas ha habido malaria. Por regresión logística se estableció que la malaria se asoció con conocer cómo se adquiere, consultar al médico tradicional y tener más de 15 años en Corozal. Conclusiones: Las plantas que la población de este estudio reportan no muestran evidencia científica como antimalaricos. Es importante una mayor presencia de las autoridades de salud y su trabajo conjunto con el médico tradicional para lograr estrategias más efectivas(AU)


Introduction: Malaria is one of the most important infectious disease and to treat it in addition to medicines the population uses medicinal plants. The objective was to establish the factors associated with malaria and the plants used for its treatment in inhabitants of Corozal. Method: A survey was applied with sociodemographic questions about housing, knowledge and attitudes, in addition to the medicinal plants used to treat it. Results: 48% use medicinal plants alone or with medicines, Gliricidia sepium (rat poisson) and Acmella oppositifolia (Opposite-leaf Spotflower) are the most used. In 48% of the homes there has been malaria. By logistic regression it was established that malaria was associated with knowing how it is acquired, consulting the traditional doctor and living in Corozal for more than 15 years. Conclusions: The plants that the population of this study report usimg do not show scientific evidence antimalarials. A greater presence of health authorities and their joint work with the traditional doctor for more effective strategies is important(AU)

ABSTRACT

Hay dos tipos principales de tejido adiposo; el subcutáneo, que es menos activo metabólicamente, y el tejido adiposo visceral, que secreta constantemente citocinas inflamatorias y está relacionado a enfermedades metabólicas y cardiovasculares. Nuestro objetivo fue identificar la asociación entre el exceso de grasa visceral y la severidad de enfermedad en pacientes con COVID-19. Se realizó un estudio observacional analítico que incluyó a pacientes con COVID-19 admitidos al Hospital Carrión de Huancayo, Perú. Se utilizó la balanza de bioimpedancia para cuantificar la composición corporal, la variable dependiente fue la severidad de enfermedad. Se utilizó el análisis de regresión logística para determinar la asociación de la grasa visceral y otros parámetros antropométricos con severidad de enfermedad. Se analizaron a 120 personas con COVID-19, la edad promedio fue 50 años, el sexo masculino fue 60%. De acuerdo a los valores de la composición corporal emitidos por el equipo de bioimpedancia: La grasa visceral > 15Kg (OR 7,31; p = 0,001); la grasa corporal total > 35% (OR 5,58; p = 0,009) y el exceso de peso > 20Kg (OR 6,96; p = 0,011) fueron los parámetros asociados a enfermedad severa por COVID-19. La relación positiva entre el perímetro abdominal y la cantidad de grasa visceral fue significativo (p = 0,01). En la composición corporal, el exceso de grasa visceral es el mayor parámetro asociado a enfermedad severa por COVID-19(AU)


There are two main types of adipose tissue; the subcutaneous, which is less metabolically active, and the visceral adipose tissue, which constantly secretes inflammatory cytokines and is related to metabolic and cardiovascular diseases. Our objetive was to identify the association between the excess of visceral fat and disease severity in COVID-19 patients. An analytical observational study was carried out which included patients with COVID-19 admitted to the Carrión Hospital in Huancayo, Peru. The bioimpedance balance was used to quantify the body composition; the dependent variable was the severity of the disease. A logistic regression analysis was used to determine the association of visceral fat and other anthropometric parameters with the severity of the disease. Out of 120 people with COVID-19 were analyzed, the average age was 50 years, the male sex was 60%. According to the body composition values issued by the bioimpedance team: Visceral fat> 15Kg (OR 7.31; p = 0.001); Total body fat> 35% (OR 5.58; p = 0.009) and excess weight> 20Kg (OR 6.96; p = 0.011) were the parameters associated with severe disease due to COVID-19. The positive relationship between abdominal circumference and the amount of visceral fat was significant (p = 0.01). In body composition, excess visceral fat is the main parameter associated with severe COVID-19 disease(AU)

ABSTRACT

INTRODUCTION: Kidney transplantation (KT) is the renal replacement therapy (RRT) of choice for patients with chronic kidney disease (CKD). However, not every KT is successful and some patients persist on RRT. OBJECTIVE: To model a logistic regression with pre- and post-KT risk covariates capable of predicting secondary allograft dysfunction in need of RRT or reaching stage V of CKD until the first six months post-KT. METHODS: Cohort with KT recipients from Northeastern Brazil. Medical records of KT performed between 2011-2018 were analyzed. KT-recipients with insufficient data or who abandoned follow-up were excluded. The covariables analyzed were: demographic; infectious; pre- and post-KT comorbidities; panel reactive-antibodies; number of HLA mismatches; acute rejection episodes mediated by T-cell (ACR) or antibodies (AAR) six months after KT; and laboratory tests six months after KT. RESULTS: Covariates with higher risk for the analyzed outcomes six months after KT were: elderly KT recipients (OR:1.41; CI95%:1.01-1.99), time between onset of RRT and KT (ΔT-RRT&KT)>10years (OR:3.54; CI95%:1.27-9.87), diabetes mellitus (DM) pre-KT (OR:3.35; CI95%:1.51-7.46), pyelonephritis (OR:2.45; CI95%:1.24-4.84), polyomavirus nephropathy (OR:4.99; CI95%:1.87-13.3), AAS (OR:4.82; CI95%:1.35-17.2), 24h-proteinuria ≥300mg/24h (OR:5.05; CI95%:2.00-12.7) and serum calcium (Ca) <8.5mg/dL (OR:4.72; CI95%:2.00-11.1). The multivariate model presented an accuracy of 88.1% and the mean variance inflation factor is 1.81. CONCLUSION: Elderly-recipients, ΔT-RRT&KT>10 years, pre-KT DM, and post-KT aggressions until six months (pyelonephritis, polyomavirus nephropathy, ABMR, 24h-proteinuria≥300mg/24h, and Ca<8.5mg/dL) are associated with high predictive power for secondary allograft dysfunction in need of RRT or reaching CKD stage V until the first six months post-KT.


INTRODUÇÃO: Transplante renal (TR) é a terapia renal substitutiva (TRS) de escolha para pacientes com doença renal crônica (DRC). Entretanto, nem todo TR é bem-sucedido e alguns pacientes persistem em TRS. OBJETIVO: Modelar uma regressão logística com covariáveis de risco pré e pós-TR preditora da disfunção secundária do aloenxerto com necessidade de TRS ou alcance ao estágio V da DRC até os primeiros seis meses pós-TR. MÉTODOS: Coorte com receptores transplantados realizado em hospital no Nordeste brasileiro. Analisou-se registros médicos dos TR realizados entre 2011-2018. Receptores com dados insuficientes ou que abandonaram seguimento foram excluídos. Foram analisadas covariáveis: demográficas; infecciosas; comorbidades pré e pós-TR; painel de reatividade; incompatibilidades de HLA; episódios de rejeições agudas mediadas por células-T ou por anticorpos; exames laboratoriais seis meses pós-TR. RESULTADOS: Receptores idosos (OR:1,41; IC95%:1,01-1,99), tempo entre início da TRS e TR (∆T-TRS&TR)>10 anos (OR:3,54; IC95%:1,27-9,87), diabetes mellitus (DM) pré-TR (OR:3,35; IC95%:1,51-7,46), pielonefrite (OR:2,45; IC95%:1,24-4,84), nefropatia por poliomavírus (OR:4,99; IC95%:1,87-13,3), RAMA (OR:4,82; IC95%:1,35-17,2), proteinúria de 24h (Pt24h) ≥300mg/24h (OR:5,05; IC95%:2,00-12,7) e cálcio sérico (Ca)<8,5mg/dL (OR:4,72; IC95%:2,00-11,1) foram identificadas como covariáveis de maior risco para os desfechos analisados até seis meses pós-TR. O modelo multivariado apresentou acurácia de 88,1% e fator de inflação da variância médio de 1,81. CONCLUSÃO: Receptores idosos, ∆T-TRS&TR>10anos, DM pré-TR e agressões até seis meses pós-TR (pielonefrite, nefropatia por poliomavírus, RAMA, Pt24h≥300mg/24h e Ca<8,5mg/dL), apresentam alto poder preditivo para disfunção secundária do aloenxerto com necessidade de TRS ou alcance ao estágio V da DRC até os primeiros seis meses pós-TR.

ABSTRACT

Abstract Background Cardiovascular diseases (CVDs) are the main cause of morbidity and mortality in Brazil. Objective To provide population-based data on prevalence and factors associated with CVD risk factors. Methods Individuals aged ≥20 years from two editions of the cross-sectional Health Survey of São Paulo focusing on Nutrition (ISA-Nutrition), performed in Sao Paulo city in 2008 (n=590) and 2015 (n=610), were evaluated for: obesity, central obesity, waist/height ratio, high blood pressure (HBP), dyslipidemia, diabetes, and number of CVD risk factors ≥3. Prevalence was estimated according to complex survey procedures. Factors associated with cardiovascular risk factors were assessed using logistic regression, with statistical significance of p<0.05. Results Obesity and older age were associated with higher odds of all cardiovascular risk factors investigated, except for dyslipidemia. HBP was positively associated with being Black/Brown and negatively associated with being physicaly active in leisure time. Women were more likely to have increased adiposity indicators and three or more cardiovascular risk factors than men. Those with higher education had lower chances of having diabetes, HBP and dyslipidemia, and those with higher income had higher chances of having three or more risk factors. Former smokers had higher odds of diabetes, obesity, and high waist/height ratio, and smokers had higher odds of high non-HDL cholesterol levels. From 2008 to 2015, there was an increase (p<0.001) in the prevalence of diabetes (6.9% to 17.3%), HBP (31.9% to 41.8%), dyslipidemia (51.3% to 67.6%), and number of CVD risk factors ≥3 (18.9% to 34.1%). Conclusion This study shows increasing prevalence of CVD risk factors in adult population in Sao Paulo and may support the definition of target groups and priority actions on CVD prevention and treatment.

ABSTRACT

BACKGROUND@#Cancer prevention is a crucial challenge in preventive medicine. Several studies have suggested that voluntary health check-ups and recommendations from health professionals are associated with increased participation in cancer screening. In Japan, it is recommended that individuals aged 40-74 years should undergo annual health check-ups; however, the compliance to this recommendation is approximately <50%. According to the national survey, individuals who do not undergo annual health check-ups are at a higher risk for cancer. However, to the best of our knowledge, no previous study has investigated the association between the use of health check-ups and the incidence rate of cancer. We hypothesised that not undergoing periodic health check-ups and/or less use of outpatient medical services are predictors for advanced cancer.@*METHODS@#To explore the relationship between health check-up or outpatient service utilisation and cancer incidence, this retrospective cohort study used data at two time points-baseline in 2014 and endpoint in 2017-from the National Health Insurance (NHI) claims and cancer registry. A multivariable logistic regression analysis was performed to investigate whether cancer diagnosis was associated with health check-up or outpatient service utilisation.@*RESULTS@#A total of 72,171 participants were included in the analysis. The results of the multivariable logistic regression showed that individuals who skipped health check-ups had a higher risk of cancer diagnosis (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.04-1.40). Moreover, not undergoing health check-ups increased the risk of advanced-stage cancer (OR, 1.78; 95% CI, 1.29-2.44). Furthermore, increased rate of outpatient service utilisation was negatively associated with advanced cancer diagnosis.@*CONCLUSIONS@#This is the first study reporting that not undergoing health check-ups is a predictor of cancer diagnosis and advanced cancer stage. Primary prevention strategies for NHI members who do not undergo health check-ups must be reassessed. Moreover, future research should examine secondary prevention strategies, such as health education and recommendations from health professionals to facilitate adequate utilisation of preventive health services.

ABSTRACT

The present study explored the correlation of coronary heart disease(CHD) with blood stasis syndrome in postmenopausal women with artery elasticity and endothelial function indexes and evaluated the diagnostic efficacy of the prediction model via logistic regression and receiver operating characteristic(ROC) curve model. A retrospective comparison was made between 366 postmenopausal CHD patients from August 1, 2020, to September 30, 2021, in the Department of Cardiology of Integrated Traditional Chinese and Western Medicine of China-Japan Friendship Hospital, who were divided into the blood stasis syndrome group(n=196) and the non-blood stasis syndrome group(n=170). General clinical characteristics of the two groups were compared. Multivariate logistic regression analysis was used to probe the correlation of CHD with blood stasis syndrome in postmenopausal women with brachial-ankle pulse wave velocity(baPWV), ankle-brachial index(ABI), and flow-mediated dilatation(FMD), and the ROC curve was drawn to evaluate the diagnostic efficiency of the prediction model. Multivariate logistic regression analysis showed that the correlation coefficients of CHD with blood stasis syndrome in postmenopausal women with baPWV, ABI, and FMD were 1.123, 0.109, and 0.719, respectively(P=0.004, P=0.005, P<0.001),and the regression equation for predicting probability P was P=1/[1+e~(-(3.131+0.116×baPWV-2.217×ABI-0.330×FMD))]. ROC curve analysis suggested that in the context of baPWV≥19.19 m·s~(-1) or ABI≤1.22 or FMD≤9.7%, it was of great significance to predict the diagnosis of CHD with blood stasis syndrome in postmenopausal women. The AUC of baPWV, ABI, FMD, and prediction probability P was 0.763, 0.607, 0.705, and 0.836, respectively. The AUC of prediction probability P was higher than that of each index alone(P<0.001), and the sensitivity and specificity were 0.888 and 0.647, respectively. The results demonstrate that baPWV, ABI, and FMD are independently correlated with CHD with blood stasis syndrome in postmenopausal women, and show certain independent predictive abilities(P<0.05). The combined evaluation of the three possesses the best diagnostic efficiency.

Abstract Objective To assess the professional nursing practice environment from the perspective of students in the context of the COVID-19 pandemic. Methods Cross-sectional study conducted with a convenience sample of 43 students attending the last grade of the Nursing Undergraduate course at a federal university located in the city of São Paulo, SP, Brazil. Characterization variables: sex, ethnicity, age, place of internship and a question on whether they have worked and/or did an extracurricular internship in the area. The Practice Environment Scale - Brazilian validated version, consisting of 24 items and five subscales, was applied. Data were analyzed using descriptive and inferential statistics with the following tests: Kruskal Wallis, ANOVA, Tukey, t-student and Mann Whitney. Logistic regression analysis was performed. A significance level of p<0.005 was considered. Results Subscale 3 "Staffing and resource adequacy" was the only one with an unfavorable mean (53.49%). The variable "having worked and/or done an extracurricular internship" was statistically significant in Subscale 2 "Nurse manager ability, leadership and support of nurses" (p=0.003). On overall mean, students rated the environment as favorable (p<0.001). Conclusion Despite the context, most students rated the environment as favorable. The variable "having worked and/or done an extracurricular internship" was statistically significant. The training of leaders, the strengthening of continuing education programs and involvement of nurses in activities, problem solving and internal committees of the institution are considered preambles to offer qualified care within a close to favorable environment of professional practice.

ABSTRACT

Resumen Introducción: El Bajo Peso al Nacer (BPN) tiene múltiples causas y continúa siendo un problema que afecta diferentes regiones de Colombia. Objetivo: Determinar los factores asociados con BPN en el Hospital Universitario Departamental de Nariño. Materiales y métodos: Estudio de casos y controles que incluyó madres y recién nacidos, cuyo parto fue atendido entre noviembre de 2014 y junio de 2015. Resultados: El riesgo de BPN fue mayor en mujeres con edad entre 10-19 años (OR=7,79, IC95%=2,61-23,23), con antecedente de infección vaginal durante el embarazo (OR=4, IC95%=1,26-12,66), nivel educativo primaria incompleta (OR=10,93, IC95%=1,51-79,13) o primaria completa (OR=2,94, IC95%=1,06-8,13), afiliadas al régimen de salud subsidiado (OR=4,96, IC95%=1,71-14,41). El riesgo de tener un recién nacido con BPN se redujo un 10% (OR=0,90, IC95%=0,84-0,96) por cada incremento en una unidad de Índice de Masa Corporal y un 76% (OR=0,23, IC95%=0,16-0,34) por cada incremento en una semana de gestación. Conclusiones: La mayoría de factores de riesgo identificados pueden ser prevenidos o intervenidos precozmente desde un enfoque de salud pública.


Abstract Introduction: Low Birth Weight (LBW) has multiple causes and continues to be a problem that affects different regions of Colombia. Objective: To determine factors associated with LBW in the Departmental University Hospital of Nariño (Colombia). Materials and methods: A case-control study that included newborns and mothers whose delivery took place between November 2014 and June 2015. Results: Risk of LBW was higher in: women aged between 10-19 years (OR=7.79, 95%CI=2.61-23.23); with history of vaginal infection during pregnancy (OR=4, 95%CI=1.26-12.66); and those affiliated with the subsidized health regimen (OR=4.96, 95%CI=1.71-14.41). The risk of having a newborn with LBW was reduced by 10% (OR=0.90, 95%CI=0.84-0.96) for each one unit increase in Body Mass index, and by 76% (OR=0.23, 95%CI=0.16-0.34) for each increase in one week of gestation. Conclusions: Most of the identified risk factors can be prevented or intervened with through an early public health approach.

ABSTRACT

OBJECTIVE: Depression and suicidal behavior have been described as major problems among medical students. The aim of this study was to assess the prevalence of depression and suicidal behavior among medical students of an institution and to investigate possible associated variables. METHODS: The authors carried out a cross-sectional study through a self-administered questionnaire, including the Beck Depression Inventory (BDI) and the Beck's Suicide Intent Scale (BSIS) instruments. The diagnosis of depression was based on an instrument adapted according to the DSM-IV and ICD-10 criteria. Logistic regression was performed to search for depression predictor variables. RESULTS: In a total of 381 students, the prevalence of depression was 27.6%. Suicidal ideation of moderate to severe intensity was observed in 10.5% of the sample. About 6% of students had previously attempted suicide. Consumption of licit and illicit drugs was frequent among the participants, reaching 78% and 24% of the sample, respectively. The demand for specialized treatment was lower than expected among students with depression. Logistic regression revealed that female gender, reduced interpersonal contact with friends, reduced physical activity, difficulty in facing new situations and high perception of personal pressure were risk factors for depression. CONCLUSION: The prevalence of depression and suicidal behavior among medical students is higher than in the general population. There is a need for further studies to enable a better understanding of the risk factors and variables at play, which is fundamental for the development of early intervention strategies and support for students.


OBJETIVO: Depressão e comportamento suicida têm sido descritos como problemas importantes entre estudantes de medicina. O objetivo deste estudo foi avaliar a prevalência de depressão e de comportamento suicida entre estudantes de medicina de uma instituição e investigar possíveis variáveis associadas. MÉTODOS: Os autores realizaram um estudo transversal por meio de um questionário autoaplicável, incluindo os instrumentos Inventário de Depressão de Beck (BDI) e Escala de Intenção Suicida de Beck (BSIS). O diagnóstico de depressão foi baseado em instrumento adaptado de acordo com os critérios do DSM-IV e da CID-10. Foi realizada análise de regressão logística para avaliar variáveis preditoras de depressão. RESULTADOS: Em um total de 381 alunos, a prevalência de depressão foi de 27,6%. A ideação suicida de intensidade moderada a grave foi observada em 10,5% da amostra. Cerca de 6% dos alunos já haviam tentado suicídio. O consumo de drogas lícitas e ilícitas foi frequente entre os participantes, atingindo 78% e 24% da amostra, respectivamente. A demanda por tratamento especializado foi menor do que o esperado entre os alunos com depressão. A regressão logística revelou que o sexo feminino, a redução do contato interpessoal com os amigos, a redução da atividade física, a dificuldade de enfrentar novas situações e a alta percepção de pressão pessoal foram fatores de risco para depressão. CONCLUSÃO: A prevalência de depressão e comportamento suicida entre estudantes de medicina é maior do que na população em geral. São necessários mais estudos para permitir uma melhor compreensão dos fatores de risco em jogo, o que é fundamental para o desenvolvimento de estratégias de intervenção precoce e apoio a esses estudantes.

ABSTRACT

Introducción: en México existe escasa información respecto al vínculo entre el síndrome metabólico (MetS), el nivel socioeconómico (NSE) y la calidad de vida (CdV) de la población. Objetivo: evaluar la asociación entre sujetos que tienen alto riesgo de desarrollar MetS con NSE y CdV. Métodos: se invitó a participar a pacientes de la UMF-2 del IMSS y del Centro Urbano-SSA Clínica-1. Se recolectaron medidas antropométricas y se aplicaron los cuestionarios AMAI, SF12 y ESF-I para NSE, CdV y MetS, respectivamente. La asociación se determinó calculando rho de Spearman. El riesgo se evaluó mediante regresión logística (razon de momios e intervalo de confianza del 95%). Resultados: la diferencia entre NSE (193  53 frente a 124  50) y CdV (86.3  14.8 frente a 56.0  25.4) fue significativa entre los grupos de bajo y alto riesgo, respectivamente (p < 0.001). Hubo una fuerte correlación negativa entre las puntuaciones de la ESF-I y NSE (rho = -0.623, p < 0.001) así como con la CdV (rho = -0.719, p < 0.001). El riesgo de MetS aumentó al disminuir el NSE (C+: OR = 6.4, IC95%: 3.2 - 13.0; D: OR = 66.1, IC95%: 23.2 - 188.3), mientras que el aumento de la CdV lo atenuó (OR = 0.93, IC95%: 0.91 - 0.94). Interesantemente, la CdV mitigó el efecto del NSE (C+: OR = 4.5, IC95%: 2.1 - 9.6; D: OR = 11.9, IC95%: 3.8 - 37.6). Conclusión: Una menor CdV y NSE aumentan el riesgo de MetS en la región centro de México; sin embargo, el aumento en la CdV podría disminuir el efecto que tiene el NSE en el desarrollo de MetS.


Background: In Mexico there is little information regarding the link between metabolic syndrome (MetS), socioeconomic status (SES) and quality of life (QoL) Objective: To assess the association between subjects who are at high risk of developing MetS with SES and QoL. Methods: Patients attending UMF-2 IMSS or Centro Urbano-SSA Clínica-1 were asked to participate. Anthropometric measures were collected, the AMAI, SF12, and ESF-I questionnaire where apply for SES, QoL, and MetS, respectively. Association were determined by calculating Spearman's rho and the risk (odds ratio and 95% confidence-interval) was assessed using logistic regression. Results: The difference of SES (193  53 vs. 124  50) and QoL (86.3  14.8 vs. 56.025.4) questionnaires were significantly between low-risk and high-risk groups, respectively (p < 0.001). There was a negative correlation between ESF-I and SES (rho = -0.623, p < 0.001) as well as the QoL (rho = -0.719, p < 0.001). MetS risk was augmented by decreasing SES (C+: OR = 6.4, 95%IC: 3.2-13.0; D: OR = 66.1, 95%IC: 23.2-188.3), whereas increasing QoL attenuated it (OR = 0.93, 95%CI: 0.91-0.94). However, QoL mitigated the effect of SES (C+: OR = 4.5, 95%IC: 2.1-9.6; D: OR = 11.9, 95%IC: 3.8-37.6).

ABSTRACT

Abstract Introduction: Stroke is a complication that causes considerable morbidity and mortality during the heart surgery postoperative period (incidence: 1.3 to 5%; mortality: 13 to 41%). Models for assessing the risk of stroke after heart surgery have been proposed, but most of them do not evaluate postoperative morbidity. The aim of this study was to develop a risk score for postoperative stroke in patients who undergo heart surgery with cardiopulmonary bypass. Methods: A cohort study was conducted with data from 4,862 patients who underwent surgery from 1996 to 2016. Logistic regression was used to assess relationships between risk factors and stroke. Data from 3,258 patients were used to construct the model. The model's performance was then validated using data from the remainder of the patients (n=1,604). The model's accuracy was tested using the area under the receiver operating characteristic (ROC) curve. Results: The prevalence of stroke during the postoperative period was 3% (n=149); 59% of the patients who exhibited this outcome were male, 51% were aged ≥ 66 years, and 31.5% of the patients died. The variables that remained as independent predictors of the outcome after multivariate analysis were advanced age, urgent/emergency surgery, peripheral arterial occlusive disease, history of cerebrovascular disease, and cardiopulmonary bypass time ≥ 110 minutes. The area under the ROC curve was 0.71 (95% confidence interval 0.66 - 0.75). Conclusion: We were able to develop a risk score for stroke after heart surgery. This score classifies patients as low, medium, high, or very high risk of a surgery-related stroke.

ABSTRACT

RESUMEN Fundamento: la deserción escolar debe ser analizada en un contexto multivariado para identificar sus causas y efectos, de ningún modo debe ser atribuida a una sola causa. Objetivo: determinar la capacidad predictiva de algunos factores sobre la deserción escolar de estudiantes de Medicina, a través de un modelo de regresión logística múltiple. Métodos: se realizó un estudio analítico, predictivo en 87 estudiantes de Medicina matriculados en el curso 2015-2016. Se aplicaron métodos teóricos y empíricos y se realizó en dos etapas: en la primera se identificaron las variables más asociadas a la deserción escolar a través de un análisis bivariado; y en la segunda, se analizó la capacidad de estas variables para predecir la deserción a través de la regresión logística (análisis multivariado). Resultados: en el análisis bivariado, nueve variables mostraron relación significativa con la deserción escolar; al someterlas al análisis multivariado (correlación y regresión logística), solo cuatro mantuvieron la significación estadística, por lo que finalmente fueron las escogidas como variables predictoras. Conclusiones: la deserción escolar en estudiantes de la carrera de Medicina puede predecirse por la combinación sinérgica de los cuatro predictores: dedicarle al estudio menos de 15 horas por semana, el sexo femenino, la repitencia escolar y el bajo rendimiento académico en Morfofisiología.


ABSTRACT Background: school dropout should be analyzed in a multivariate context to identify its causes and effects; in no way, it should be attributed to a single cause. Objective: to determine the predictive capacity of some factors on the school dropout of medical students, through a multiple logistic regression model. Methods: an analytical, predictive study was carried out in 87 medical students enrolled in the 2015-2016 academic year. Theoretical and empirical methods were applied and it was carried out in two stages: in the first, the variables most associated with school dropout were identified through a bivariate analysis; and in the second, the ability of these variables to predict dropout was analyzed through logistic regression (multivariate analysis). Results: in the bivariate analysis, nine variables showed a significant relationship with school dropout; when subjected to multivariate analysis (correlation and logistic regression), only four maintained statistical significance, that´s why they were finally chosen as predictor variables. Conclusions: school dropout in Medicine students can be predicted by the synergistic combination of the four predictors: dedicating less than 15 hours per week to study, female sex, school repetition and low academic performance in Morphology-physiology.

CONCLUSÃO: Houve importante prevalência de ideação suicida, associada a fatores sociodemográficos, do estilo de vida, socioafetivos e psíquicos.


OBJECTIVE: To estimate the prevalence and analyze the factors associated with suicidal ideation in high school and college students. METHODS: Epidemiological, transversal, analytical study, carried out in Montes Claros, MG, Brazil. For data collection, a questionnaire was applied, containing questions related to sociodemographic, school, occupational, lifestyle, socio-affective and psychological conditions. Suicidal ideation was investigated using an item in the Beck Depression Inventory. In the data analysis, descriptive statistics of the variables and hierarchical Logistic Regression were used to evaluate the factors associated with suicidal ideation. RESULTS: There was a prevalence of suicidal ideation of 11.6% among high school students and 9.8% in higher education. In high school, the associated factors were: female gender (OR: 2.14; 95% CI: 1.39-3.27), drug use (OR: 3.25; 95% CI: 1.40-7.52), alcohol consumption (OR: 2.50; 95% CI: 1.54-4.04), feeling of anger and hostility (OR: 1.73; 95% CI: 1.05-2.87), burnout syndrome (OR: 2.27; 95% CI: 1.31-3.95). In higher education, the following factors were identified: absence of a partner (OR: 2.19; 95% CI: 1.68-4.14), night shift (OR: 0.51; 95% CI: 0.36-0.72), tobacco consumption (OR: 1.74; 95% CI: 1.05-2.91), absence of optimistic thinking (OR: 2.66; 95% CI: 1.75-4,03), internet addiction (OR: 1.64; 95% CI: 1.08-2.50), high body check habit (OR: 1.69; 95% CI: 1.15-2.50). Impaired sleep (OR: 1.62; 95% CI: 1.02- 2.59; OR: 1.62; 95% CI: 1.05-2.51), impaired dialog interaction (OR: 3.04; 95% CI: 1.93-4.82; OR: 2.66; 95% CI: 1.81-3.92), feeling of disappointment and tension (OR: 4.80; 95% CI: 2.97-7.77; OR: 4.02; 95% CI: 2.69-6.02) were associated factors in both groups, respectively. CONCLUSION: There was an important prevalence of suicidal ideation, associated with sociodemographic, lifestyle, socio-affective and psychic factors.

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to build a prediction model to discriminate precociously hantavirus infection from leptospirosis, identifying the conditions and risk factors associated with these diseases. METHODS: A logistic regression model in which the response variable was the presence of hantavirus or leptospirosis was adjusted. RESULTS: As a result, the method selected the following variables that influenced the prediction formula: sociodemographic variables, clinical manifestations, and exposure to environmental risks. All variables considered in the model presented statistical significance with a p<0.05 value. The accuracy of the model to differentiate hantavirus from leptospirosis was 88.7%. CONCLUSIONS: Concluding that the development of statistical tools with high potential to predict the disease, and thus differentiate them precociously, can reduce hospital costs, speed up the patient's care, reduce morbidity and mortality, and assist health professionals and public managers in decision-making.

ABSTRACT

Introducción: El Síndrome de Desgaste Laboral o Burnout, es entendido como una baja resiliencia para afrontar el estrés laboral. Objetivo: Identificar factores asociados al Burnout y la prevalencia global y de cada uno de sus constructos, entre auxiliares de enfermería en un hospital de referencia de mediana y alta complejidad, en Colombia. Materiales y métodos: Estudio de casos y controles, con 183 auxiliares registradas en un hospital. Se utilizó el instrumento de Maslach y se identificaron los factores asociados utilizando la regresión Log-Binomial determinando los Odds Ratio (OR). Resultados: Los factores encontrados asociados con Burnout que aumentan la probabilidad de ocurrencia son: trabajar más de 48 horas por semana, OR=1,02 (1,01-1.05) al 90% de confianza; sentirse mal con el trabajo que se realiza OR=3,87 (1,18-10,71); el dormir siete horas o más al día OR=0,70 (0,53-0,91), disminuye la probabilidad. La prevalencia total de Burnout fue 44,7%, siendo 11,8% para agotamiento personal, 14,9% despersonalización y 47,81% pobre realización personal. Conclusiones: Los factores asociados: no dormir suficiente y sentirse mal con la tarea que se realiza, aumentan la probabilidad de desarrollar Burnout, mientras que dormir 7 o más horas diarias la disminuye. Estos hallazgos facilitarán la aplicación de medidas de control institucional.


Introduction: The Burnout syndrome is understood as a low resilience to face work stress. Objective: To identify factors and constructs associated with Burnout and its overall prevalence in nursing assistants in a reference hospital of medium and high complexity level from Colombia. Materials and methods: A case-control study was conducted on 183 nursing assistants from a hospital. The Maslach instrument and Log-Binomial regression were used to identify associated factors, determining their Odds Ratio (OR). Results: The factors found associated with Burnout that increase its probability of occurrence are: working more than 48 hours a week (OR=1.02 (1.01-1.05) 90% CI) and feeling negatively about the work being done (OR=3.87 (1.18-10.71)). However, sleeping 7 or more hours a day reduces such probability (OR=0.70 (0.53-0.91)). The total Burnout prevalence was 44.7%, the main causes being personal fatigue (11.8%), depersonalization (14.9%), and poor personal fulfillment (47.81%). Conclusions: Associated factors, such as not getting enough sleep and feeling negatively about the work being done, increase the probability to develop Burnout, while this probability decreases by sleeping 7 or more hours a day. These findings will facilitate the implementation of institutional control measures.

ABSTRACT

O objetivo deste estudo foi avaliar os efeitos das estações do parto e da inseminação, da retenção de placenta, da natimortalidade e da ordem de parto sobre o desempenho reprodutivo de vacas leiteiras. Utilizou-se a regressão logística, em que as variáveis dependentes foram concepção à primeira inseminação pós-parto e percentual de vacas prenhes no rebanho aos 100, 150 ou 200 DEL e as variáveis independentes foram a estação do parto e a estação da inseminação, a retenção de placenta, a natimortalidade e a ordem de parto. A estação do parto e a estação da inseminação influenciaram o desempenho reprodutivo, reduzindo a fertilidade das vacas nas estações quentes do ano. O atraso na primeira inseminação aumentou a concepção na primeira inseminação, mas reduziu o percentual de vacas prenhes ao longo da lactação. O desempenho reprodutivo da vaca leiteira foi afetado por vários fatores, relacionados à vaca, ao ambiente e ao manejo a ela imposto.(AU)


The objective of this study was to evaluate the effects of the calving season, insemination, placenta retention, stillbirth and birth order on the reproductive performance of dairy cows. Logistic regression was used, where the dependent variables were conception at the first postpartum insemination and the percentage of cows pregnant in the herd at 100, 150 and 200 DEL. The independent variables were delivery season and insemination season, placenta retention, stillbirth and delivery order. The calving season and the insemination season influenced reproductive performance, and in the hot seasons of the year the fertility of the cows was reduced. The delay in the first insemination increased conception in the first insemination but reduced the percentage of pregnant cows during lactation. The reproductive performance of the dairy cow was affected by several factors, related to the cow, the environment and the management imposed on it.(AU)

ABSTRACT

Introducción: El cáncer de tiroides es el tumor maligno más común originado en órganos endocrinos (más del 92 por ciento) y comprende un grupo de tumores que son diferentes clínicamente y epidemiológicamente. En los últimos años se ha incrementado el uso de los modelos predictivos en la práctica médica para determinar la mejor conducta en pacientes con tumores de la glándula tiroides. Objetivo: Desarrollar un modelo probabilístico de predicción de la recidiva en pacientes con cáncer de tiroides. Métodos: Se realizó un estudio prospectivo longitudinal, en el Hospital Militar Central Dr. Carlos J. Finlay, desde enero de 2015 hasta febrero del 2020. Se incluyeron 63 pacientes que ingresaron al estudio por muestreo aleatorio simple con remplazo, se confeccionó un modelo predictivo utilizando una regresión logística binaria en el programa R. Resultados: El grupo de edad más afectado estuvo entre los 40 y 59 años, predominó el sexo femenino y el carcinoma papilar, la vascularización y la irregularidad fueron los elementos ultrasonográficos más detectados. El estadístico de Wald fue significativo con una distribución normal en todas las variables analizadas lo cual indica que sus coeficientes son diferentes de 0 y deben ser incluidos en el modelo La variable con mayor influencia en el índice de recidiva resultó ser la diferenciación celular Conclusiones: Los factores con mayor influencia en la recidiva en la serie estudiada resultaron el grado de diferenciación, la presencia de vascularización e irregularidad en la ecografía y el tamaño tumoral con cifras similares a las reportadas nacional e internacionalmente(AU)


Introduction: Thyroid cancer is the most common malignant tumor originating in endocrine organs (more than 92%) and comprises a group of tumors that are clinically and epidemiologically different. In recent years, the use of predictive models has increased in medical practice to determine the best behavior in patients with tumors of the thyroid gland. Objective: To develop a probabilistic model for predicting recurrence in patients with thyroid cancer. Methods: A longitudinal prospective study was carried out at the Dr. Carlos J Finlay Central Military Hospital, from January 2015 to February 2020. 63 patients who entered the study by simple random sampling with replacement were included; a predictive model was made using a binary logistic regression in program R. Results: The most affected age group was between 40 and 59 years old, female sex predominated and papillary carcinoma, vascularization and irregularity were the most detected ultrasound elements. The Wald statistic was significant with a normal distribution in all variables analyzed, which indicates that their coefficients are different from 0 and should be included in the model. The variable with the greatest influence on the recurrence rate turned out to be cell differentiation. Conclusions: The final binary logistic regression model had an adequate goodness of fit and discrimination was very good, with an acceptable receiving operator area under the curve (AU)
