Feasibility of performing the 3-minute step test with remote supervision in children and adolescents with cystic fibrosis: A comparative study.

Importance: The 3-min step test is a simple option to monitor submaximal exercise capacity, although its use via remote video monitoring has not been investigated in children with cystic fibrosis (CF). Objective: This study aimed to assess the feasibility and reproducibility of performing the 3-min step test with remote supervision. Methods: A cross-sectional study including CF patients (6-18 years) from two CF services were performed. Demographic, anthropometric, clinical, and lung function data were collected and two 3-min step tests were performed: (i) in-person supervision, and (ii) remotely supervised by video monitoring. Before and after the tests, heart rate (HR), oxygen saturation (SpO2), and the Borg score for dyspnea and lower limb fatigue were monitored. Results: Twenty-three patients (10.7 ± 3.7 years) with a mean FEV1 of 89.5% ± 23.2% were included. There were no significant differences between tests, with mean differences (95% confidence intervals) in final HR of -3.3 (-8.9, 2.4), change in HR of -1.9 (-6.1, 2.1), final SpO2 of 0.3 (-0.4, 1.0), and final dyspnea of 0.1 (-0.8, 0.9). The intraclass correlation coefficient was 0.852 (final HR), 0.762 (final SpO2), and 0.775 (final lower limb fatigue). Significant and moderate correlations were found between tests for final HR (r = 0.75), change in HR (r = 0.61), and final SpO2 (r = 0.61). The Bland-Altman analysis showed a mean difference in final SpO2 between tests of 0.3% (limit of agreement -3.0%, 3.5%). Interpretation: Physiological responses between tests were similar, indicating it was feasible to perform the 3-min step test with remote supervision in CF children.

Organic food consumers and producers: Understanding their profiles, perceptions, and practices.

The organic food market has been expanding across the globe as well as in Brazil. Therefore, since we considered the collection of information about the organic food market to be relevant, we decided to characterize the organic food market in the metropolitan region of Vitória, Espírito Santo. Accordingly, the aim of this study was to analyze the profile and perceptions of organic producers/traders regarding the production of organic foods, investigate the profile and perceptions of organic food consumers, and identify the factors that influence their consumption. A cross-sectional, descriptive, and exploratory survey was conducted in 2019 with 50 producers/traders and 281 organic food consumers utilizing semistructured questionnaires. A descriptive statistical analysis was performed using percentage values, media, and evaluation of proportion differences. Fisher's exact test was used to analyze differences in proportions. The producers/traders were 76.0 % male, 82.0 % white, 70.0 % married, and 60.0 % attended elementary school. The commercial production of organic foods is mainly motivated by health and financial issues. A lack of labor (52.0 %) and an absence of government/credit support (40.0 %) were the greatest obstacles related to organic food production. The consumers were mostly female (75.1 %), white people (53.4 %), married people (44.5 %), and people with at least one degree (76.5 %). While the consumption of mainly organic fruits and vegetables was motivated by aspects related to health, factors such as poor access to sales points (27.8 %) and price (26.7 %) also limited the increase in consumption. Both consumers and producers/traders related to the consumption and production of organic food with health concerns revealed the important role of these foods in promoting the population's quality of life. However, for this growing market, there is a need for an integration between political authorities, producers, and consumers.

Triglyceride-glucose index demonstrates reasonable performance as a screening tool but exhibits limited diagnostic utility for insulin resistance: Data from the ELSA-Brasil cohort.

Insulin resistance (IR) is a key risk factor for chronic metabolic diseases, but its laboratory diagnosis is still costly; thus, the triglyceride-glucose (TyG) index has been proposed as a surrogate method. Our aim was to provide a detailed analysis of cutoffs and test the hypothesis that the TyG index would present reasonable performance parameters for IR screening. This is a cross-sectional study with baseline data from 12,367 eligible participants of both sexes (aged 35-74 years) from the Brazilian Longitudinal Study of Adult Health. TyG correlation and agreement with the Homeostasis Model Assessment for Insulin Resistance were analyzed. Positive and negative predictive values (PV+, PV-) and likelihood ratio (LR+, LR-) were calculated. A moderate positive correlation between TyG and Homeostasis Model Assessment for Insulin Resistance was observed (Pearson r = 0.419). The area under the receiver operating characteristic curve of TyG for IR diagnosis was 0.742 and the optimal cutoff was 4.665, reaching a kappa agreement value of 0.354. For this cutoff, a PV+ of 59.3% and PV- of 76.0%, as well as an LR+ of 2.07 and LR- of 0.45 were obtained. Alternatively, because high sensitivity is desired for screening tests, selecting a lower cutoff, such as 4.505, increases the PV- to 82.1%, despite decreasing the PV+ to 50.8%. We conclude that TyG has important performance limitations for detecting IR, but that it may still be reasonably useful to help screening for IR in adults because it can be calculated from low-cost routine blood tests.

Examining the Usage Patterns of Non-Nutritive Sweeteners among Non-Diabetic Individuals: Insights from the Longitudinal Study of Adult Health (ELSA-Brasil).

BACKGROUND: Although non-nutritive sweeteners (NNSs) were formulated primarily for sugar-restricted diets, nowadays, their consumption has become widespread among the general population. Thus, the purpose of this study was to estimate the prevalence of the regular use of NNSs and their associated factors among non-diabetic individuals from the baseline of the Longitudinal Study of Adult Health (ELSA-Brasil). METHODS: In total, 9226 individuals were analysed, and the regular consumption of NNSs was defined as follows: NSSs are used at least once a day. Associations between exposure and outcomes were analysed using chi-square and Student's t-tests. Significant variables were inserted into a binary logistic regression model to determine the adjusted association measures (significance level of 5%). RESULTS: The prevalence of regular NNS consumption was 25.7%. Regular NNS consumption increased with age, categories of BMI, income, and schooling. The odds of regularly consuming NNSs were 1.9-times higher among women, 6.1-times higher among obese individuals, and 1.8-times higher among those with higher schooling and income. CONCLUSIONS: Specific groups seem to present a larger association relative to the use of NNS. Based on the significant overall prevalence of the regular use of NNSs, a discussion regarding country-wide policies related to their intake is needed to address recent WHO directions concerning this additive.

Regenerative and translational medicine in COPD: hype and hope.

COPD is a common, preventable and usually progressive disease associated with an enhanced chronic inflammatory response in the airways and lung, generally caused by exposure to noxious particles and gases. It is a treatable disease characterised by persistent respiratory symptoms and airflow limitation due to abnormalities in the airways and/or alveoli. COPD is currently the third leading cause of death worldwide, representing a serious public health problem and a high social and economic burden. Despite significant advances, effective clinical treatments have not yet been achieved. In this scenario, cell-based therapies have emerged as potentially promising therapeutic approaches. However, there are only a few published studies of cell-based therapies in human patients with COPD and a small number of ongoing clinical trials registered on clinicaltrials.gov Despite the advances and interesting results, numerous doubts and questions remain about efficacy, mechanisms of action, culture conditions, doses, timing, route of administration and conditions related to homing and engraftment of the infused cells. This article presents the state of the art of cell-based therapy in COPD. Clinical trials that have already been completed and with published results are discussed in detail. We also discuss the questions that remain unanswered about cell-based regenerative and translational medicine for COPD.

Anaphylactic reaction to praziquantel following schistosomiasis treatment.

Praziquantel (PZQ) is a medication used to treat several parasitic infections, including human schistosomiasis. Although this drug commonly causes transient adverse effects, severe hypersensitivity is rare, and only eight cases have been reported worldwide. Herein we report a case of a 13-year-old Brazilian female who developed anaphylaxis, a severe hypersensitive reaction, after taking praziquantel to treat Schistosoma mansoni infection. During a mass drug administration event in a socially vulnerable endemic area of Bahia (Brazil), after taking 60 mg/kg of praziquantel the patient developed rash and generalized edema an hour later, evolving to somnolence and hypotension. Following the anaphylactic episode, she received adequate treatment and recovered approximately 1 day later. Although praziquantel is considered safe, health professionals should be aware of potential life-threatening adverse events.

Evolution of nutritional status and associated factors among formula-fed infants with cow's milk protein allergy in a government program.

BACKGROUND: Cow's milk protein allergy (CMPA) is a common allergy in infants and can affect proper growth and development. This study verified factors associated with the evolution of the nutritional status (NS) among infants with CMPA fed with hypoallergenic formulas (HF). METHODS: This is a longitudinal study of infants (n = 1036) participating on a governmental program in Brazil. Researchers assessed Nutritional status before HF treatment (T1) and after HF treatment (T2). The causality of exposure variables on the evolution of NS was verified by Multinomial Logistic Regression (MLR). RESULTS: We observed an increase in anthropometric indexes analyzed with statistically significant results (p < 0.01). The weight/age and height/age scores showed a significant reduction in infants with nutritional deficit. The Body Mass Index (BMI) showed a decrease in the number of infants with nutritional deficit (< -2 z-score). On the other hand, there was an increase in those classified as at risk of overweight, overweight and obese. MLR showed that those who remained < 12 months in the program had a lower odds ratio (95% CI = 0.355-0.906; p = 0.018) to have inadequate NS with increasing BMI. Preterm infants were 4 times more likely (CI 95% = 1.520-10.694; p = 0.005) to have their BMI decreased and those who received nutritional counseling had a lower odds ratio (CI 95% = 0.411-0.953; p = 0.029) to maintain adequate NS. CONCLUSION: The program has a significant impact on the NS of infants with CMPA. The constant management and implementation of differentiated criteria according to the evolution of NS for the supply of HF is fundamental in the continuity of this public policy.

Development of a new non invasive prognostic stroke scale (NIPSS) including triage elements for sleep apnea and peripheral artery disease.

BACKGROUND: Although sleep apnea and peripheral artery disease are prognostic factors for stroke, their added benefit in the acute stage to further prognosticate strokes has not been evaluated. OBJECTIVES: We tested the accuracy in the acute stroke stage of a novel score called the Non-Invasive Prognostic Stroke Scale (NIPSS). PATIENTS AND METHODS: Prospective cohort with imaging-confirmed ischemic stroke. Clinical data, sleep apnea risk score (STOPBANG) and blood pressure measures were collected at baseline. Primary outcome was the 90-day modified Rankin Scale (mRS), with poor outcome defined as mRS 3-6. Area under the ROC curve (AUC) was calculated for NIPSS and compared to six other stroke prognostic scores in our cohort: SPAN-100 index, S-SMART, SOAR, ASTRAL, THRIVE, and Dutch Stroke scores. RESULTS: We enrolled 386 participants. After 90 days, there were 56% with poor outcome, more frequently older, female predominant and with higher admission National Institute of Health Stroke Scale (NIHSS). Four variables remained significantly associated with primary endpoint in the multivariable model: age (OR 1.87), NIHSS (OR 7.08), STOPBANG category (OR 1.61), and ankle-braquial index (OR 2.11). NIPSS AUC was 0.86 (0.82-0.89); 0.83 (0.79-0.87) with bootstrapping. When compared to the other scores, NIPSS, ASTRAL, S-SMART and DUTCH scores had good abilities in predicting poor outcome, with AUC of 0.86, 0.86, 0.83 and 0.82, respectively. THRIVE, SOAR and SPAN-100 scores were fairly predictive. DISCUSSION AND CONCLUSIONS: Non-invasive and easily acquired emergency room data can predict clinical outcome after stroke. NIPSS performed equal to or better than other prognostic stroke scales.

Travel-Related Diseases and Injuries in Children and Adolescents: A Post-Travel Surveillance Questionnaire Assessment.

INTRODUCTION: Children and adolescents are a relevant and increasing proportion of travelers. Injuries and infectious diseases in children are safety concerns when traveling. However, data on diseases and injuries during international travels in children are not available. The aims of this study were to analyze travel-related diseases and injuries among pediatric travelers during and after international trips, to identify risk factors for travel-associated disease, and to evaluate the compliance and effectiveness of the recommendations provided in pre-travel appointments. MATERIAL AND METHODS: We enrolled travelers aged under 18 years attending a pre-travel clinic, in a tertiary hospital (2017 - 2019); 223 of the 370 pediatric travelers attending the pre-travel clinic were included. The study was based on a questionnaire designed to address health and safety issues - vaccines and chemoprophylaxis, including side effects, the occurrence of disease or injury, diagnosis, treatment, and outcomes. RESULTS: The median age at pre-travel evaluation was eight years; 39.7% of the travelers were adolescents, 52.5% were female. The participants traveled to 40 countries across four continents, with a median travel duration of 14.5 days. Asia was the most visited continent. Traveling was safe for 84.8%. From 34 travelers who had illness/injury, gastrointestinal symptoms were elicited in 41.2%. Sixteen (47.1%) travelers required an urgent medical appointment at the destination, and no one was hospitalized. Destinations in Africa and longer trips were significantly associated with a higher occurrence of disease/injury (p = 0.023 and p < 0.001, respectively). In a multivariable model, traveling to Africa was still significantly associated with travel-related disease/injury [OR = 2.736 (1.037 - 7.234)]. CONCLUSION: Disease/injury occurred in 15.2% of pediatric travelers. Even though 47.1% of the travelers required an urgent medical appointment, the developed conditions were not severe enough to warrant hospitalization. Travels to Africa and longer trips seem to be associated with a higher risk of disease and injury.

Introdução: As crianças e adolescentes representam uma proporção relevante e crescente de viajantes. As doenças infeciosas e as lesões em crianças durante viagens internacionais são motivo de preocupação relacionada com segurança; no entanto, os dados na idade pediátrica são amplamente desconhecidos. Os objetivos deste estudo foram analisar as doenças e lesões relacionadas com as viagens ocorridas em viajantes em idade pediátrica, durante e após viagens internacionais, identificar fatores de risco para a ocorrência de doenças associadas à viagem, e avaliar o cumprimento e a eficácia das recomendações fornecidas na consulta pré-viagem. Material e Métodos: Incluímos viajantes com idade inferior a 18 anos avaliados na consulta do viajante num hospital terciário (2017 - 2019). O estudo baseou-se num questionário, desenhado para abordar questões de saúde e segurança ­ vacinas e quimioprofilaxia, incluindo efeitos colaterais, ocorrência de doença ou lesão, diagnóstico, tratamento e resultado. Resultados: Foram incluídos 223 dos 370 viajantes pediátricos observados na consulta do viajante. A mediana da idade à data da consulta era oito anos, 39,7% eram adolescentes e 52,5% eram do sexo feminino. Os participantes viajaram para 40 países, em quatro continentes, e a mediana da duração da viagem foi 14,5 dias. O continente asiático foi o mais visitado. A viagem foi segura em 84,8% dos casos. Nos 34 viajantes que apresentaram doença/lesão, verificaram-se sintomas gastrointestinais em 41,2%. Dezasseis (47,1%) viajantes necessitaram de consulta médica urgente no destino e nenhum foi hospitalizado. Destinos em África e viagens mais longas foram associados, significativamente, a maior ocorrência de doença/lesão (p = 0,023 e p < 0,001, respetivamente). No modelo multivariável, viajar para África foi associado, significativamente, a doença/lesão [OR = 2,736 (1,037 - 7,234)]. Conclusão: A viagem associou-se a doença/lesão em 15,2% dos viajantes pediátricos. Embora não requerendo hospitalização, 47,1% dos viajantes necessitaram de consulta médica urgente. África e viagens mais longas parecem estar associados a risco maior de doenças/lesões.

A sex-related mediating effect of uric acid in the association between body composition and blood pressure in children and adolescents.

The increase in blood pressure (BP) during somatic growth might have direct determinants but also mediating factors. We investigated whether uric acid (UA) and other metabolic factors would mediate the association between body composition components and BP. A cross-sectional study was conducted in 928 children and adolescents (aged 6-18 years), in which body composition and blood biochemistry were evaluated. Structural equation modeling was performed to test the direct and indirect pathways between systolic blood pressure (SBP) and body composition parameters. Muscle mass (MM) showed a strong direct effect on BP, regardless of sex. In girls, a mediating pathway through UA was not significant, but the association between fat mass (FM) and MM with SBP was mediated by the cluster of metabolic factors. In boys, both MM and FM were associated with SBP through a mediating pathway via UA, but not via the cluster of metabolic factors. The association between body composition and BP in children and adolescents has a complex design and also has a sex-specific mediating component. The increase in the UA levels may affect BP levels early in boys. Also, metabolic changes elicited by FM contribute to the increase in BP at an early age in girls. Novelty: MM showed a strong direct effect on BP, regardless of sex. In girls, the association between FM and MM with SBP was mediated by the cluster of metabolic factors. In boys, both MM and FM were associated with SBP through a mediating pathway via UA.

Mesenchymal stromal cells-based therapy in a murine model of elastase-induced emphysema: Simvastatin as a potential adjuvant in cellular homing.

Chronic Obstructive Pulmonary Disease - COPD is characterized by the destruction of alveolar walls associated to a chronic inflammatory response of the airways. There is no clinical therapy for COPD. In this context, cell-based therapies represent a promising therapeutic approach for chronic lung disease. The goal of this work was to evaluate the effect of simvastatin on cell-based therapy in a mice emphysema model. Female FVB mice received intranasal instillation of elastase (three consecutive doses of 50 µL) in order to promote pulmonary emphysema. After 21 days of the first instillation, the animals were treated with Adipose-Derived Mesenchymal Stromal Cells (AD-MSC, 2.6 × 106) via retro-orbital infusion associated or not with simvastatin administrated daily via oral gavage (15 mg/kg/15d). Before and after these treatments, the histological and morphometrical analyses of the lung tissue, as so as lung function (whole body plethysmography) were evaluated. PAI-1 gene expression, an upregulated factor by ischemia that indicate a low survival of transplanted MSC, was also evaluated. The result regarding morphological and functional aspects of both lungs, presented no significant difference among the groups (AD-MSC or AD-MSC + Simvastatin). However, significant anatomical difference was observed in the right lung of the both groups of mice. The results shown a higher deposition of cells in the right lung, with might to be explained by anatomical differences (slightly higher right bronchi). Decreased levels of PAI-1 were observed in the simvastatin treated groups. The pulmonary ventilation was similar between the groups with only a tendency to a lower in the elastase treated animals due to a low respiratory frequency. In conclusion, the results suggest that both AD-MSC and simvastatin treatments could promote an improvement of morphological recovery of pulmonary emphysema, that it was more pronounced in the right lung.

Identification of a Prenyl Chalcone as a Competitive Lipoxygenase Inhibitor: Screening, Biochemical Evaluation and Molecular Modeling Studies.

Cyclooxygenase (COX) and lipoxygenase (LOX) are key targets for the development of new anti-inflammatory agents. LOX, which is involved in the biosynthesis of mediators in inflammation and allergic reactions, was selected for a biochemical screening campaign to identify LOX inhibitors by employing the main natural product library of Brazilian biodiversity. Two prenyl chalcones were identified as potent inhibitors of LOX-1 in the screening. The most active compound, (E)-2-O-farnesyl chalcone, decreased the rate of oxygen consumption to an extent similar to that of the positive control, nordihydroguaiaretic acid. Additionally, studies on the mechanism of the action indicated that (E)-2-O-farnesyl chalcone is a competitive LOX-1 inhibitor. Molecular modeling studies indicated the importance of the prenyl moieties for the binding of the inhibitors to the LOX binding site, which is related to their pharmacological properties.

Food safety knowledge, attitudes and practices of food handlers: A cross-sectional study in school kitchens in Espírito Santo, Brazil.

BACKGROUND: The adoption and evaluation of good practices in food handling in food service are essential to minimizing foodborne diseases. The present study aimed to evaluate food safety knowledge, attitudes, and practices of food handlers in schools in Vitória, Brazil. METHODS: A cross-sectional study was carried out in the school food services of the municipal network of Vitória-ES. The sample of food handlers was obtained by convenience and comprised food handlers involved with preparation and other kitchen-related activities. The instrument consisted of a structured questionnaire with 36 six questions that included sociodemographic characteristics, knowledge, attitudes, and practices (KAP) related to good practices and food safety. The questionnaire was answered by 172 food handlers. Pearson correlation test, T-test, Tukey's test and multiple linear regression analysis were conducted. Data entry and analysis were done using SPSS v.20 software. RESULTS: Most of the participants were female (96.5%, n = 166), were 40 to 49 years old (44.8%, n = 78), attended high school (57.9%, n = 99), had up to 5 years of experience in the role (39.5%, n = 68). Some of them had participated at least 4 times in training (74.4%, n = 128) of which the most recent session had occurred within 3 months (52.0%, n = 44). The lowest score was obtained for knowledge (7.1 ± 1.22). All the models presented significant results for the F-test. This result show good model fit and results ranging from 1.5 to 2.5 on the Durbin Watson test of residual autocorrelation. The linear regression analysis allowed us to identify that the knowledge score increased with experience, but it was significant only for those who had spent up to 10 years in the role. The knowledge score was associated with experience and training time. Attitudes were significantly related to the schooling and training time. The increase in the classification of practices is shown only through a classification of attitudes. CONCLUSIONS: Although the food handlers' knowledge level in general was considered as sufficient, it was inferior to their scores for attitudes and practices regarding certain food safety concepts. Food safety training is ongoing in these units and covers the main aspects that favour the transformation of knowledge into appropriate attitudes and practices.

Impact of the mHealth strategy in sodium consumption markers: AvaliaSal study / Impacto da estratégia mHealth em marcadores do consumo de sódio: estudo AvaliaSal

ABSTRACT Objective Evaluate the effectiveness of mHealth strategy on sodium consumption markers. Methods Intervention study carried out with 175 adults (20-59 years), from an educational institution of Vitória, Espírito Santo State. Participants were made aware through posters, oral approach and electronic media. Anthropometric, hemodynamic, socioeconomic, health, and dietary practices data was collected in two stages. After the first assessment, participants were randomized into two groups: Intervention Group and Control Group. The Intervention Group included 21 electronic messages and 3 videos on healthy eating focusing on the goal to reduce sodium intake for 3 months. Behavioral changes were assessed using the Generalized Estimation Equation (p-value <0.05). Results At baseline, no significant differences in socioeconomic, anthropometric and health variables, and eating practices between groups were observed. The stock broth cube was the most used ready processed seasoning. After the intervention, a reduction in the use of stock broth was observed only in the intervention group (β=0.615; p=0.016). In addition, 73% of the intervention group participants reported that the messages were clear, 67% reported that they were useful, and 48% stated they followed the guidelines. Conclusion There was a reduction in the frequency of use of stock broth cubes, demonstrating the potential effect of the m-Health strategy on sodium consumption markers in individuals without a hypertension medical diagnosis.

Além disso, 73% do Gruo de Intervenção relataram que as mensagens foram claras; 67% afirmaram que as mensagens foram úteis e 48% disseram que seguiram as orientações. Conclusão Foi observada uma redução da frequência do uso de caldo pronto, demonstrando potencial da estratégia m-Health sobre marcadores do consumo de sódio em participantes sem diagnóstico de hipertensão.

[Underestimation of obesity and overweight based on self-report measures in the general population: prevalence and a proposal for correction models]. / Subestimativa de obesidade e sobrepeso a partir de medidas autorrelatadas na população geral: prevalência e proposta de modelos para correção.

The study's objectives: compare self-report measures of weight and height with direct measures; assess the impact of these discrepancies on body mass index (BMI) and prevalence of overweight and obesity; and apply correction models to the self-report measures and assess the degree of improvement in the corrected measures produced with the use of these models. A cross-sectional study was performed, assessing 4,151 adults (18 to 60 years) participating in the São Paulo Megacity Epidemiological Study. Linear regression models stratified by sex were proposed for correction of self-reported measures. Agreement was assessed with the intraclass correlation coefficient for the direct measures, self-report measures, and corrected measures, and kappa coefficient for BMI classification categories. Self-reported weight and the resulting BMI were underestimated, while height was overestimated, compared to direct measures. With all the correction models, the corrected measures were closer to the direct measures. Prevalence rates for excess weight, calculated by self-report measures, were underestimated by 24% in men and by 28% in women; with corrections, the underestimation decreased to 8% and 10%, respectively. The results showed moderate agreement for self-report measures and substantial agreement for corrected measures compared to direct measures. The use of correction equations for self-report data proved to be a useful method for producing more trustworthy estimates of prevalence of overweight and obesity in the general population, usually estimated from self-report measures of weight and height in population surveys.

Os objetivos deste artigo são: (i) comparar medidas autorrelatadas de peso e estatura com medidas aferidas; (ii) avaliar o impacto dessas discrepâncias sobre o índice de massa corporal (IMC) e as prevalências de sobrepeso e obesidade; e (iii) aplicar modelos de correção das medidas autorrelatadas e avaliar o grau de melhoria das medidas corrigidas produzidas pelo uso desses modelos. Realizou-se estudo transversal, com avaliação de 4.151 adultos (18 a 60 anos) participantes do Estudo Epidemiológico dos Transtornos Mentais São Paulo Megacity. Foram propostos e testados modelos de regressão linear estratificados por sexo, para a correção das medidas autorrelatadas. Para avaliar a concordância, usou-se o coeficiente de correlação intraclasse para as medidas aferidas, medidas autorrelatadas e medidas corrigidas, bem como o coeficiente kappa para as categorias de classificação do IMC. O peso autorrelatado e o IMC resultantes foram subestimados, ao passo que a estatura foi superestimada, comparados às medidas aferidas. Com todos os modelos de correção, as medidas corrigidas tornaram-se mais próximas às medidas aferidas. As prevalências de excesso de peso, quando calculadas a partir das medidas autorrelatadas, estavam subestimadas em 24% em homens e 28% em mulheres. Com as correções, a subestimativa diminuiu para 8% e 10%, respectivamente. Identificou-se concordância moderada para as medidas autorrelatadas e concordância substancial para as medidas corrigidas, quando comparadas às medidas reais. O uso de equações de correção para dados autorrelatados mostrou-se um método útil para produzir estimativas mais fidedignas da prevalência de excesso de peso e obesidade na população geral, geralmente estimadas a partir de medidas de peso e estatura autorrelatadas nos inquéritos populacionais.

Los objetivos fueron: comparar medidas autoinformadas de peso y estatura con medidas evaluadas; evaluar el impacto de estas discrepancias sobre el índice de masa corporal (IMC) y las prevalencias de sobrepeso y obesidad; y aplicar modelos de corrección de las medidas autoinformadas y evaluar el grado de mejoría de las medidas corregidas, producidas por el uso de esos modelos. Se realizó un estudio transversal evaluando a 4.151 adultos (18 a 60 años), participantes en el Estudio Epidemiológico São Paulo Megacity. Se propusieron y probaron modelos de regresión lineal estratificados por sexo para la corrección de las medidas autoinformadas. Para evaluar la concordancia, se usó el coeficiente de correlación intraclase para las medidas evaluadas, medidas autoinformadas y medidas corregidas, y el coeficiente kappa para las categorías de clasificación del IMC. El peso autoinformado y el IMC resultantes fueron subestimados mientras la estatura fue sobrestimada, comparados con las medidas evaluadas. Con todos los modelos de corrección, las medidas corregidas se convirtieron en más cercanas a las medidas evaluadas. Las prevalencias de exceso de peso, cuando se calculan a partir de las medidas autoinformadas, estaban subestimadas en un 24% en hombres y un 28% en las mujeres; con las correcciones, la infravaloración disminuyó a un 8% y un 10%, respectivamente. Se identificó una concordancia moderada para las medidas autoinformadas y una concordancia sustancial para las medidas corregidas, cuando se compararon con las medidas reales. El uso de ecuaciones de corrección para dados autoinformados se mostró un método útil para producir estimaciones más fidedignas de la prevalencia de exceso de peso y obesidad en la población general, generalmente estimadas a partir de medidas de peso y estatura autoinformadas en las encuestas poblacionales.

Consumo de alcohol y perfil lipídico en participantes del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil) / Alcohol consumption and lipid profile in participants of the Longitudinal Study of Adult Health (ELSA-BRASIL)

Introducción: las dislipidemias son definidas comúnmente por niveles bajos de HDL-c y altos niveles de triglicéridos y LDL-c. Son varios los factores relacionados con esta patogénesis y uno de ellos es el consumo de alcohol, presentado divergencias entre la cantidad y el tipo de bebida alcohólica que debe consumirse para encontrar efectos de asociación con los parámetros lipídicos. Objetivo: investigar la relación entre el consumo de alcohol y el tipo de bebida alcohólica y los parámetros lipídicos HDL-c y triglicéridos en participantes del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil). Métodos: estudio observacional, transversal, desarrollado a partir de los datos de la línea de base del ELSA-Brasil (2008-2010). El consumo de bebidas alcohólicas fue estimado en dosis/semana y categorizado por terciles (1-7, 7-14 y > 14 dosis/semana) y por tipo de bebida alcohólica (cerveza, vino y destilados). Los parámetros lipídicos fueron utilizados como datos continuos. Se realizaron modelos de regresión lineal para cada tipo de bebida alcohólica. El nivel de confianza fue del 5%. Resultados: el HDL-c y los triglicéridos aumentaron con el incremento del número de dosis/semana de cerveza. El consumo de vino de 1-7 y 7-14 dosis/semana elevó el HDL-c. Por el contrario, los triglicéridos tienden a disminuir cuando el consumo es de 1-7 dosis/semana. El consumo de destilados de > 14 dosis/semana aumentó las concentraciones de HDL-c. Conclusión: el HDL-c aumentó sus niveles plasmáticos con el consumo de todos los tipos de bebidas alcohólicas. Por el contrario, los triglicéridos disminuyen con el consumo de vino

Introduction: dyslipidemias are commonly defined by low levels of HDL-c and high levels of triglycerides and LDL-c as an alteration in the functioning of lipoproteins. Several factors are related to this pathogenesis, and one of them is the consumption of alcohol, presenting divergences between the amount and the type of alcoholic drink that must be consumed to find effects of association with the lipid parameters. Objective: to investigate the relationship between alcohol consumption and the type of alcoholic beverage with HDL-c and triglycerides in participants of the Longitudinal Study of Adult Health (ELSA-Brazil). Methods: observational, cross-sectional study, developed from baseline data from the ELSA-Brazil (2008-2010). The consumption of alcoholic beverages was estimated in doses/week and categorized in tertiles (1-7, 7-14 and > 14 doses/week) and by type of alcoholic beverage (beer, wine and distillates). Lipid parameters were used as continuous data. Linear regression models were performed for each type of alcoholic beverage. The confidence level was 5%. Results: HDL-c and triglycerides increased with the increase in the number of doses/week of beer. The consumption of wine between 1-7 and 7-14 doses/week raises HDL-c. Conversely, triglycerides tend to decrease when consumption is 1-7 doses/week. Consumption of distillates > 14 doses/week increase HDL-c. Conclusion: HDL-c increased plasma levels directly with the consumption of all types of alcoholic beverages. Conversely, triglycerides decrease with wine consumption

Alterações hepáticas detectadas durante a inspeção post mortem de bovinos abatidos em um frigorífico sob serviço de inspeção federal / Hepatic pathologies detected during bovine post mortem inspection in a slaughterhouse under federal inspection

A inspeção de carnes é um método bastante eficiente na prevenção de problemas de saúde pública, além de diminuir perdas econômicas e aumentar a qualidade dos produtos cárneos que chegam ao consumidor. O objetivo do presente trabalho foi identificar as lesões patológicas que mais acometem o fígado bovino durante o abate dessa espécie em um frigorífico. Para realização desse trabalho foram observados os abates e a inspeção post mortem de 21.045 bovinos, nos meses de dezembro de 2016, janeiro e fevereiro de 2017, em um frigorífico sob Serviço de Inspeção Federal no município de Juiz de Fora, Minas Gerais. As principais alterações encontradas e suas frequências médias, em porcentagem, foram: abscesso 3,17%; cirrose 0,11%; congestão 0,25%; fasciolose 0,44%; telangiectasia 0,19% e tuberculose 0,09%. É possível identificar lesões hepáticas durante a inspeção post mortem de bovinos, sendo, no presente estudo, as alterações mais observadas abscesso e fasciolose.
