Equations for Prediction of Body Adiposity in Patients With Chronic Kidney Disease Undergoing Hemodialysis.

OBJECTIVES: The prevalence of obesity in the population has increased and excess body adiposity is one of the main nutritional disorders in patients with chronic kidney disease (CKD) on hemodialysis (HD). The objective of this study was to develop equations using anthropometric measurements to predict the total and abdominal body adiposity of patients with CKD on HD. METHODS: This is a cross-sectional study evaluating 323 patients with CKD on HD in city in northeastern Brazil. Measurements and anthropometric indicators were correlated with percentage of body fat (%BF) and visceral fat (VF, in kg) measured by dual energy X-ray absorptiometry. Multiple linear regression models based on different combinations of anthropometric measurements were adjusted to develop the equations, with subsequent cross-validation. RESULTS: Of the 323 patients, 62.2% were male and 46.5% were aged between 40 and 59 years. The equation selected to estimate %BF included weight, height, waist and hip circumferences, and triceps and suprailiac skin folds, presenting high predictive capacity (R2 = 0.771). The equation selected to estimate VF included weight, height, waist circumference, hip circumference, and sum of skin folds (R22 = 0.796). CONCLUSIONS: The proposed equations efficiently predicted the %BF and VF (kg) of patients with CKD on HD, thereby serving as viable indicators in clinical practice.

Proposition of an Energy Intake Estimating Scale through Item Response Theory.

BACKGROUND: Traditional methods for assessing individual energy consumption often involve lengthy and intricate procedures. This study aims to introduce an Energy Consumption Estimation Scale, utilizing Item Response Theory (IRT) for adolescents aged 18-19 years. METHODS: This psychometric investigation applies IRT to 93 items extracted from a validated food frequency questionnaire. The study encompasses a representative sample of 2515 adolescents from the São Luís birth cohort in Brazil. The latent trait, energy intake, is derived using IRT and subsequently validated through hierarchical multiple linear regression modeling. Significance was established at p < 0.05. RESULTS: A Samejima's model was successfully fitted (CFI and TLI > 0.9 and RMSEA < 0.08), effectively capturing variations across all energy consumption levels. Factors associated with the latent trait demonstrate consistent behavioral patterns. Adolescents with higher energy intake exhibited increased consumption of dairy products, artificially sweetened beverages, and seasonal fruits and vegetables. CONCLUSIONS: The proposed Energy Consumption Estimation Scale demonstrates a reliable measurement of energy intake and serves as a practical and concise alternative for assessing energy consumption among adolescents. These findings suggest the potential for adapting similar models for different age groups and incorporating diverse food items based on the obtained results.

Dietary Patterns, Nutritional Status and Inflammatory Biomarkers in Adolescents from the RPS Birth Cohort Consortium.

This study aimed to identify the dietary patterns (DPs) of adolescents and assess indicators of subclinical inflammation. It was a cross-sectional study aligned with the RPS cohort with data from São Luís, Maranhão, Brazil. We evaluated 511 adolescents between 18-19 years old. DPs were identified with a factor analysis of the principal components. Nutritional status was assessed with body mass index and body fat percentages. Hierarchical modeling was performed using a linear regression to estimate the beta coefficient (ß) of the independent variables with the dependent variables interleukin-6 and high-sensitivity C-reactive protein (hs-CRP). Five DPs were identified: energy-dense, sugar-sweetened beverages and breakfast cereals, prudent, traditional Brazilian and alcoholic and energy beverages. Greater adherence to the prudent DP was associated with a lower concentration of interleukin-6 (ß = -0.11; p value = 0.040). Greater adherence to the DP "traditional Brazilian" and "alcoholic and energy beverages" were associated with increased IL-6, mediated by the nutritional status. A higher BMI (ß = 0.36; p value = <0.001) and %BF (ß = 0.02; p value = 0.014) were associated with higher hs-CRP concentrations. The nutritional status and "prudent" pattern were associated with inflammatory biomarkers. These findings show that a higher consumption of fresh and minimally processed foods and the adequacy of the nutritional status are protective factors for the inflammatory process.

Association of D-Dimer, C-Reactive Protein, and Ferritin with COVID-19 Severity in Pregnant Women: Important Findings of a Cross-Sectional Study in Northern Brazil.

BACKGROUND: The COVID-19 pandemic has had a great impact on pregnant women due to the broad clinical spectrum of the disease. The present study investigated the profile of three biomarkers during hospital admission of pregnant women-D-dimer, C-reactive protein (CRP), and ferritin-and their correlation with the severity and outcome of COVID-19. METHODS: The cross-sectional study included 226 pregnant women hospitalized in the city of Belém, Pará, Northern Brazil, from April 2020 to July 2021. Epidemiological and laboratory data were obtained from medical records, and all pregnant women underwent RT-PCR molecular testing for the detection of SARS-CoV-2. RESULTS: In total, 121 (53.5%) were positive and 105 (46.5%) were negative for SARS-CoV-2 using RT-PCR. Most pregnant women (49.5%) with COVID-19 were between 26 and 34 years old, were residing in the interior of the state of Pará (51.2%), and were in the third gestational trimester (71.9%). In addition, 71.1% of them were admitted to the ward and 28.9% were admitted to the intensive care unit (ICU), with 90.9% surviving COVID-19. The concentrations of D-dimer (p = 0.0122) and ferritin (p ≤ 0.0001) were significantly higher among pregnant women with COVID-19, especially among those hospitalized in the ICU. CONCLUSION: Ferritin and D-dimer seem to serve as important biomarkers for the prognosis of COVID-19 in pregnant women, which was not observed for CRP.

Determinar o risco cardiovascular pelo Escore de Framingham em indivíduos hipertensos e/ou diabéticos acompanhados em uma unidade de saúde. Estudo transversal com 141 indivíduos com avaliação de dados sociodemográficos, econômicos, clínicos, nutricionais e laboratoriais e aplicação do Escore de Framingham. A média de idade foi 58,5 ±10,5 anos; 67,4% foram mulheres; prevalência de hipertensão arterial, 79,4%, diabetes mellitus, 46,8%; e ambas as comorbidades, 26,2%. A análise apontou diferença por sexo: mulheres apresentaram maior índice de massa corporal (p=0,002), colesterol total (p=0,047) e lipoproteína de alta densidade (p<0,001). O risco cardiovascular foi: 27%, risco baixo; 35,4%, moderado; e 37,6%, alto. Houve maior predomínio de alto risco cardiovascular nos homens (56,5%). Na estratificação do risco cardiovascular, os fatores relacionados ao alto risco foram: maiores idades (p<0,001), maiores valores de colesterol total (p=0,002) e pressão arterial sistólica (p=0,001), maior prevalência de diabetes mellitus (p=0,041) e menores valores de lipoproteína de alta densidade (p=0,016).

To determine the cardiovascular risk using the Framingham Risk Score in hypertensive and/or diabetic individuals followed-up in a health unit. Cross-sectional study with 141 individuals evaluating sociodemographic, economic, clinical, nutritional, and laboratory data, and application of the Framingham Risk Score. Mean age was 58.5 ±10.5 years; 67.4% were women; the prevalence of hypertension was 79.4%; diabetes mellitus, 46.8%; and both comorbidities, 26.2%. The analysis pointed out difference by sex: women had higher body mass index (p=0.002), total cholesterol (p=0.047), and high-density lipoprotein (p<0.001). Cardiovascular risk was: 27%, low risk; 35.4%, moderate risk; and 37.6%, high risk. There was a higher predominance of high cardiovascular risk in men (56.5%). In the stratification of cardiovascular risk, the factors related to high risk were older age (p<0.001), higher values of total cholesterol (p=0.002) and systolic blood pressure (p=0.001), higher prevalence of diabetes mellitus (p=0.041), and lower values of high-density lipoprotein (p=0.016).

National Vaccine Coverage Survey 2020: methods and operational aspects.

OBJECTIVE: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. METHODS: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. RESULTS: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. CONCLUSION: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

Lessons From the Portuguese Solid Organ Donation and Transplantation System: Achieving Success Despite Challenging Conditions.

Over the past two decades, Portugal has become one of the world leaders in organ donation and transplantation despite significant financial constraints. This study highlights how Portugal achieved success in organ donation and transplantation and discusses how this information might be used by other countries that are seeking to reform their national programs. To accomplish this goal, we performed a narrative review of relevant academic and grey literature and revised our results after consultation with two national experts. Our findings were then synthesized according to a conceptual framework for organ donation and transplantation programs. Our results revealed several key strategies used by the Portuguese organ donation and transplantation program, including collaboration with Spain and other European nations, a focus on tertiary prevention, and sustained financial commitment. This report also explores how cooperative efforts were facilitated by geographical, governmental, and cultural proximity to Spain, a world leader in organ donation and transplantation. In conclusion, our review of the Portuguese experience provides insight into the development of organ donation and transplantation systems. However, other countries seeking to reform their national transplant systems will need to adapt these policies and practices to align with their unique cultures and contexts.

Appropriate neck circumference and waist-to-height ratio cut-off points as predictors of obesity and cardiovascular risk in adolescents.

OBJECTIVE: To determine neck circumference (NC) and waist-to-height ratio (WHtR) cut-off points as predictors of obesity and cardiovascular risk in adolescents. METHODS: Cross-sectional study developed with a subsample of 634 adolescents aged 18 and 19 years belonging to the third phase of the "RPS" cohort (Ribeirão Preto, Pelotas and São Luís) carried out in 2016. The area under the ROC curve (AUC) was identified to assess the predictive capacity of NC and WHtR in relation to the percentage of body fat (%BF), obtained by air displacement plethysmography (ADP), and the cardiovascular risk estimated by the Pathobiological Determinants of Atherosclerosis in Youth (PDAY). RESULTS: The prevalence of obesity by %BF was 7.6% in males and 39.4% in females (p-value <0.001), and the high PDAY risk was 13.8% and 10.9%, respectively. For males, NC cut-off point was 44.0 cm and the AUCs were 0.70 (95%CI 0.58-0.83) to predict obesity and 0.71 (95%CI 0.62-0.80) to predict high cardiovascular risk; for females, NC cut-off point was 40 cm and the AUCs were 0.75 (95%CI 0.69-0.80) and 0.63 (95%CI 0.53-0.73), respectively. WHtR cut-off point was 0.50 for both sexes; for males, the AUCs to predict obesity and high risk according to PDAY were 0.90 (95%CI 0.80-0.99) and 0.73 (95%CI 0.63-0.82), respectively; for females, they were 0.87 (95%CI 0.83-0.90) and 0.55 (95%CI 0.45-0.65), respectively. CONCLUSION: WHtR and NC are good discriminators to assess obesity and cardiovascular risk in adolescents, especially in males.

Dietary evaluation of sodium intake in patients with chronic kidney disease / Evaluación dietética del consumo de sodio en pacientes con enfermedad renal crónica

Introduction: high sodium intake is a risk factor for diseases such as systemic arterial hypertension, stroke, left ventricular hypertrophy, and chronic kidney disease (CKD). Objective: to evaluate the correlation between estimated sodium intake by dietary intake and 24-hour urinary excretion in patients with non-dialysis CKD. Material and Methods: a cross-sectional study with 151 individuals. Demographic, socioeconomic, clinical and lifestyle data were evaluated. Sodium was dosed in 24-hour urine and estimated by 24-hour Food Recall (R24h). To evaluate the association between demographic, anthropometric, nutritional and laboratory variables with sodium excretion in 24-hour urine, variance analysis (ANOVA) or Kruskal-Wallis test were used. The correlation between 24-hour urinary sodium excretion and dietary sodium intake was performed by Spearman's correlation coefficient. Results: mean age was 60.8 ± 11.8 years, 51.7 % were women. Hypertensive patients, 88.9 %; diabetics, 45.0 %; and 39.1 % were in stage 3B of CKD. Median sodium excretion in 24-hour urine was 112.2 mmol/L and R24h intake was 833.8 mg/day. Individuals belonging to the highest tertile of sodium excretion (T3) presented lower PTH values, and those with lower tertile (T1), higher serum HDL-c levels (p < 0.05). There was no statistical correlation between dietary sodium intake and 24-hour urine excretion (p-value = 0.241). Conclusion: the non-correlation between sodium obtained by 24-hour urinary excretion and dietary intake demonstrates the fragility of the estimation of sodium excretion through the dietary survey.

Introducción: la ingesta elevada de sodio es un factor de riesgo para enfermedades como la hipertensión arterial sistémica, el accidente cerebrovascular, la hipertrofia ventricular izquierda y la enfermedad renal crónica (ERC). Objetivo: evaluar la correlación entre la ingesta estimada de sodio y la excreción urinaria de 24 horas en pacientes con ERC sin diálisis.Métodos: estudio transversal con 151 individuos. Se evaluaron datos demográficos, socioeconómicos, clínicos y de estilo de vida. El sodio se cuantificó en orina de 24 horas y se estimó en Food Recall (R24h) de 24 horas. Para evaluar la asociación entre variables demográficas, antropométricas, nutricionales y de laboratorio con la excreción de sodio en orina de 24 horas, se utilizó el análisis de varianza (ANOVA) o la prueba de Kruskal-Wallis. La correlación entre la excreción urinaria de sodio de 24 horas y la ingesta de sodio en la dieta se realizó mediante el coeficiente de correlación de Spearman. Resultados: la edad media fue de 60,8 ± 11,8 años, el 51,7 % eran mujeres. Los pacientes hipertensos eran el 88,9 %; los diabéticos, el 45,0 %, y el 39,1 % se encontraban en estadio 3B de ERC. La mediana de excreción de sodio en orina de 24 horas fue de 112,2 mmol/L y la ingesta de R24h fue de 833,8 mg/día. Los individuos pertenecientes al tercil más alto de excreción de sodio (T3) presentaron valores de PTH más bajos y aquellos con niveles más bajos de tercil (T1), mayores niveles séricos de HDL-c (p < 0,05). No hubo correlación estadística entre la ingesta de sodio en la dieta y la excreción de orina durante 24 horas (valor p = 0,241). Conclusión: la ausencia de correlación entre el sodio obtenido por excreción urinaria de 24 horas y la ingesta dietética demuestra la fragilidad de la estimación de la excreción de sodio a través de la encuesta dietética.

Neuroblastoma olfatório radioinduzido: um relato de caso / Radioinduced olfactory neuroblastoma: a case report

O neuroblastoma olfatório é um tumor neuroepitelial raro, que cresce do epitélio olfatório na placa cribriforme ou na porção superior da cavidade nasal. Apresenta dois picos de incidência, entre 11 e 20 anos e entre 51 e 60 anos. O comprometimento da mucosa olfatória na porção superior das fossas nasais pode sinalizar a possibilidade de neuroblastoma olfatório, principalmente quando associado à lesão intracraniana com cistos adjacentes. Possui alta incidência de recidiva, e há a necessidade de acompanhamento prolongado. Apresentamos o caso de uma paciente do sexo feminino, 15 anos, com histórico de rabdomiossarcoma embrionário com anaplasia de órbita esquerda, submetida a tratamento quimiorradioterápico até 2009. Permaneceu por mais de 10 anos em controle, procurando assistência médica, por queixa de anosmia de início há um mês associada a cefaleia, aumento da protrusão de olho esquerdo e ptose. A tomografia computadorizada e ressonância magnética revelaram o surgimento de volumosa formação expansiva extra-axial, de contorno lobulado e limites parcialmente definidos, centrada na base craniana anterior, em situação mediana, que determinava osteodestruição do etmoide, do plano esfenoidal e das fóveas etmoidais, com projeção nas fossas nasais e, através das lâminas papiráceas, em ambas as cavidades orbitárias, sobretudo na esquerda, onde rechaçava o músculo reto medial e mantinha contato com o globo ocular. A massa apresentava impregnação difusa pelo contraste, exceto por cistos situados na periferia do componente de extensão intracraniano. Sendo considerado o surgimento tardio da massa descrita ao longo do controle evolutivo da lesão primária orbitária, bem como a localização e as características intrínsecas, foi sugerida a possibilidade de neuroblastoma olfatório radioinduzido, sendo tal hipótese confirmada pelo estudo histopatológico. Foi realizada a ressecção total do tumor e quimioterapia adjuvante, estando programado o início de radioterapia

Olfactory neuroblastoma is a rare neuroepithelial tumor that grows from the olfactory epithelium in the cribriform plate or upper portion of the nasal cavity. It has two incidence peaks, between 11 and 20 years and between 51 and 60 years. Compromising the olfactory mucosa in the upper portion of the nasal cavities may signal the possibility of olfactory neuroblastoma, especially when associated with an intracranial lesion with adjacent cysts. It has a high incidence of recurrence, and there is a need for prolonged follow-up. We present the case of a female patient, 15 years old, with a history of anaplastic embryonal rhabdomyosarcoma of the left orbit, who underwent chemoradiotherapy treatment until 2009. She remained under control for more than 10 years, having sought medical assistance, complaining of anosmia that had started a month before, associated with headache, increased protrusion of the left eye and ptosis. Computed tomography and magnetic resonance imaging revealed the emergence of a large extra-axial expansive formation, with a lobulated contour and partially defined limits, centered on the anterior cranial base, in a median position, which determined osteodestruction of the ethmoid, sphenoid plane and ethmoidal foveas, with projection in the nasal cavities and, through the papyraceous laminae, in both orbital cavities, especially in the left, where it repelled the medial rectus muscle and maintained contact with the ocular globe. The mass showed diffuse contrast enhancement, except for cysts located at the periphery of the intracranial extension component. Considering the late appearance of the mass described during the follow up of the primary orbital lesion, as well as the location and intrinsic characteristics, the possibility of radio-induced olfactory neuroblastoma was suggested, and this hypothesis was confirmed by the histopathological study. Total resection of the tumor and adjuvant chemotherapy were performed, and the start of radiotherapy is scheduled

RESUMO Objetivo: Inquérito nacional de cobertura vacinal aos 12 e 24 meses de idade foi realizado para investigar as quedas nas coberturas a partir de 2016. Métodos: Amostra de 37.836 nascidos vivos das coortes de 2017 e 2018 residentes nas capitais, Distrito Federal (DF) e 12 cidades com mais de 100 mil habitantes, acompanhados nos primeiros 24 meses por registros nas cadernetas de vacinação. Setores censitários foram estratificados segundo condições socioeconômicas, e o mesmo número de crianças foi incluído para cada estrato. Calcularem-se coberturas vacinais de cada vacina e coberturas completas aos 12 e 24 meses, doses aplicadas, válidas e oportunas. Fatores familiares, maternos e da criança associados à cobertura foram pesquisados. Os motivos para não vacinar analisados foram: contraindicações médicas, dificuldades de acesso, problemas no funcionamento do programa e hesitação vacinal. Resultados: Os resultados preliminares mostram que menos de 1% das crianças não foram vacinadas, as coberturas pelo esquema completo são menores que 75% em todas as capitais e no DF, as vacinas com mais de uma dose perdem cobertura progressivamente, há diferenças entre os estratos socioeconômicos, favoráveis aos estratos mais altos em algumas cidades e aos estratos mais baixos em outras. Conclusão: Houve realmente redução da cobertura vacinal em todas as capitais e no DF para as crianças nascidas em 2017 e 2018, denotando piora na execução do Programa Nacional de Imunizações durante os anos de 2017 a 2019. O inquérito realizado não mensurou os impactos da pandemia de COVID-19 que podem ter reduzido ainda mais as coberturas vacinais.

Validation of a food frequency questionnaire for assessing the intake of food groups and nutrients in adults / Validação de um questionário de frequência alimentar para avaliação do consumo de grupos de alimentos e nutrientes em adultos

ABSTRACT Objective: To validate a food frequency questionnaire used to assess food consumption among adults in a Brazilian cohort. Methods: Cross-sectional study conducted on 100 adults. Food intake was assessed by the food frequency questionnaire and by two 24-hour recalls. Validation was performed for nutrients (n=19) and food groups (n=21). Results: Moderate deattenuated Pearson's correlation coefficients (>0.4) were observed for the consumption of dairy products, breads and crackers, rice, pasta and tubers, leafy vegetables, other vegetables, fats, sweetened drinks, sandwiches and savory snacks, and nuts, and for the following nutrients (deattenuated and adjusted for energy intake): fiber, calcium, and vitamins A, B2, and C. Based on almost all food groups and nutrients assessed, ≥70% of the individuals were classified into the same or adjacent quartile for both methods, except for red and pork meat, snacks, nuts, phosphorus, potassium, and vitamin B3. The food groups and nutrients with fair kappa agreement (>0.2) were: dairy products, other vegetables, sweetened drinks, breakfast cereals, energy, carbohydrate, iron, and vitamin A. Conclusion: The food frequency questionnaire has proven useful for estimating the intake of some nutrients and food groups of the subjects evaluated. Only the intake of red and pork meat, snacks, nuts, vitamin B3, phosphorus and potassium were estimated with less accuracy.

RESUMO Objetivo: Validar um questionário de frequência alimentar para avaliar o consumo alimentar de adultos em uma coorte brasileira. Métodos: Estudo transversal realizado com 100 adultos. A ingestão alimentar foi avaliada pelo questionário de frequência alimentar e por dois recordatórios de 24 horas. A validação foi realizada para nutrientes (n=19) e grupos de alimentos (n=21). Resultados: Coeficientes de correlação de Pearson deatenuados moderados (>0,4) foram observados para o consumo de laticínios, pães e biscoitos, arroz, macarrão e tubérculos, vegetais folhosos, outros vegetais, gorduras, bebidas adoçadas, sanduíches e salgadinhos, e nozes, e para os seguintes nutrientes (deatenuados e ajustados para ingestão de energia): fibra, cálcio e vitaminas A, B2 e C. Com base em quase todos os grupos de alimentos e nutrientes avaliados, ≥70% dos indivíduos foram classificados no mesmo quartil ou quartil adjacente para ambos os métodos, exceto para carnes vermelhas e suínas, salgadinhos, nozes, fósforo, potássio e vitamina B3. Os grupos de alimentos e nutrientes com concordância kappa justa (>0,2) foram: laticínios, outras verduras, bebidas açucaradas, cereais matinais, energia, carboidratos, ferro e vitamina A. Conclusão: O questionário de frequência alimentar mostrou-se útil para estimar a ingestão de alguns nutrientes e grupos de alimentos dos sujeitos avaliados. Apenas o consumo de carnes vermelhas e suínas, salgadinhos, nozes, vitamina B3, fósforo e potássio foi estimado com menor precisão.

Appropriate neck circumference and waist-to-height ratio cut-off points as predictors of obesity and cardiovascular risk in adolescents / Pontos de corte da circunferência do pescoço e da relação cintura-estatura como preditores da obesidade e risco cardiovascular em adolescentes

ABSTRACT OBJECTIVE To determine neck circumference (NC) and waist-to-height ratio (WHtR) cut-off points as predictors of obesity and cardiovascular risk in adolescents. METHODS Cross-sectional study developed with a subsample of 634 adolescents aged 18 and 19 years belonging to the third phase of the "RPS" cohort (Ribeirão Preto, Pelotas and São Luís) carried out in 2016. The area under the ROC curve (AUC) was identified to assess the predictive capacity of NC and WHtR in relation to the percentage of body fat (%BF), obtained by air displacement plethysmography (ADP), and the cardiovascular risk estimated by the Pathobiological Determinants of Atherosclerosis in Youth (PDAY). RESULTS The prevalence of obesity by %BF was 7.6% in males and 39.4% in females (p-value <0.001), and the high PDAY risk was 13.8% and 10.9%, respectively. For males, NC cut-off point was 44.0 cm and the AUCs were 0.70 (95%CI 0.58-0.83) to predict obesity and 0.71 (95%CI 0.62-0.80) to predict high cardiovascular risk; for females, NC cut-off point was 40 cm and the AUCs were 0.75 (95%CI 0.69-0.80) and 0.63 (95%CI 0.53-0.73), respectively. WHtR cut-off point was 0.50 for both sexes; for males, the AUCs to predict obesity and high risk according to PDAY were 0.90 (95%CI 0.80-0.99) and 0.73 (95%CI 0.63-0.82), respectively; for females, they were 0.87 (95%CI 0.83-0.90) and 0.55 (95%CI 0.45-0.65), respectively. CONCLUSION WHtR and NC are good discriminators to assess obesity and cardiovascular risk in adolescents, especially in males.

RESUMO OBJETIVO Determinar os pontos de corte da circunferência do pescoço (CP) e da relação cintura-estatura (RCEst) para a predição da obesidade e do risco cardiovascular em adolescentes. MÉTODOS Estudo transversal desenvolvido com uma subamostra de 634 adolescentes de 18 e 19 anos de idade pertencentes à terceira fase da coorte "RPS" (Ribeirão Preto, Pelotas e São Luís) realizada em 2016. Identificou-se a área sob a curva ROC (AUC) para avaliar a capacidade preditiva da CP e RCE em relação ao percentual de gordura corporal (%GC), obtido pela pletismografia por deslocamento de ar (PDA), e do risco cardiovascular estimado pelo Phatobiological Determinants of Atherosclerosis in Youth (PDAY).

Brazilian breast cancer patient-reported outcomes: What really matters for these women.

Introduction: Patient-Reported Outcomes (PRO) are directly reported by the patient without interpretation of the patient's response by a clinician or anyone else and pertains to the patient's health, quality of life, or functional status associated with health care or treatment. It can provide patients' perspectives regarding treatment benefit and harm beyond survival and are often the outcomes of most importance to patients. This study aims to describe and analyze outcomes reported by Brazilian women diagnosed with breast cancer and rank the most important attributes for these patients. Methods: Observational descriptive study composed of exploratory interviews followed by online questionnaires applied to a convenience sample of women diagnosed with breast cancer. Results: Twelve women were interviewed to explore the main outcomes and preferences about their treatments, such as the most common side effects and the most impacted aspects of life after diagnosis and BC treatment. Psychological, emotional, and sexual impacts were frequently described as impacted aspects. Fifty-three women, from all the five Brazilian regions, answered the online questionnaire. Following an order of importance ranking, the following outcomes were chosen, respectively: overall survival, progression-free survival; and quality of life. The treatment effects that were considered less important, among this sample, were pain and adverse events. Conclusions: Thinking about expanding the therapeutic quality of users, it is essential to take into account the experiences of patients. PRO is a trend in current research to achieve this goal, in order to influence the decisions of HTA agencies about the importance of valuing outcomes that affect patients' lives.

Co-infection of Peruvian horse sickness virus and West Nile virus associated with neurological diseases in horses from Brazil.

In 2018, during the surveillance for West Nile virus (WNV) in horses with neurological clinical signs in the state of Espírito Santo (Brazil), 19 animals were investigated, and 52 biological samples were collected for WNV diagnostic. One brain sample was positive for WNV by RT-qPCR and the virus was isolated in C6/36 cell culture and sequenced. We obtained a nearly complete genome of WNV co-infected with Peruvian horse sickness virus (PHSV) in the cell culture. After confirmation of PHSV by next-generation sequencing, a new PHSV RT-qPCR protocol was developed, which was used to detect another horse positive only for PHSV. This assay provides a simple and direct method for easy identification of PHSV from biological samples from horses and may become a useful tool in the epidemiological surveillance of this virus. It is the first case of PHSV in Brazil, and only the third country overall to report, 23 years after the first confirmed notification in Peru. Moreover, it is the first reported co-infection of PHSV and WNV in a horse with neurological signs, confirmed by RT-qPCR.

Waist-to-height ratio cut-off points to predict obesity in adolescents and association with inflammatory markers / Puntos de corte de la relación cintura-altura para predecir la obesidad en adolescentes y asociación con marcadores inflamatorios

Introduction: obesity increases inflammatory molecules and cardiovascular risk even in young populations. New indicators are being investigated, including the waist-to-height ratio (WHtR) to predict obesity and the relationship with inflammatory markers in childhood and adolescence. Objective: to identify the cut-off points of the WHtR to determine obesity and its association with inflammatory markers in adolescents in São Luís, state of Maranhão, Brazil. Methods: this is a cross-sectional study, with 2,209 adolescents aged 18 and 19, belonging to the third phase of the birth cohort entitled “RPS”, carried out in 2016. The total area under the ROC curve (AuC) was identified to assess the predictive capacity of WHtR in relation to body fat percentage (%BF), obtained by air displacement plethysmography (ADP). The association of WHtR with inflammatory markers interleukin-6 (IL-6), tumor necrosis factor (TNF-α) and c-reactive protein (CRP) was evaluated. Results: prevalence of obesity by the %BF was 10.3 % in males and 40.4 % in females. The cut-off points for the WHtR were 0.50 for females and 0.51 for males, with an AuC of 0.90 (95 % CI: 0.88-0.92) and 0.93 (95 % CI: 0.90-0.97). There was an association of elevated WHtR with higher levels of IL-6 and CRP (p < 0.05). Conclusion: the predictive capacity of WHtR for obesity was excellent. Elevated values of the WHtR were associated with early inflammatory markers. This study contributed to the identification of cut-off points for simple and low-cost anthropometric indicators. (AU)

Early weaning and family characteristics are associated with greater sodium intake in children between 13 and 35 months: BRISA birth cohort.

Children are consuming less healthy foods, and this eating behaviour exposes the child to greater Na intake. The association between family, maternal and child characteristics with Na intake by children aged 13-35 months was evaluated. A study carried out with retrospective data on 1,185 children from the Brisa cohort. The children's dietary Na intake was assessed by a 24-h diet recall survey. Values ≥ 1200 mg were considered excessive intake. The association between Na intake and independent variables was assessed by a three-level logistic hierarchical regression model. Variables with P-value < 0·05 were retained in the model. Most children were male (51·2 %), eutrophic (63·2 %) and not exclusively breast-feeding (EBF) for 6 months (58·4 %). The average Na intake was 925 mg (±410·4). The prevalence of excessive Na intake was 18·5 % and was associated with the variables children of younger mothers (< 20 years old OR = 4·04, 95 % CI 1·64, 9·99; ≥ 20 to < 35 years old OR = 2·48, 95 % CI 1·10, 5·63), having four or more children (OR = 2·51, 95 % CI 1·29, 4·89), lower family income (≥ 1 and < 3 minimum wages OR = 0·60, 95 % CI 0·39, 0·93; ≥ 3 minimum wages OR = 0·50, 95 % CI 0·30, 0·82) and not being EBF until 6 months (OR = 1·64, 95 % CI 1·14, 2·34). The average Na intake of children was higher than the recommendation for adequate intake, pointing to a high consumption of this micronutrient in the first years of life. Excessive Na intake seems to be linked to unfavourable socio-economic conditions. Avoiding early weaning is the only possible intervention in this scenario.
