Vitamin D and the Metabolic Phenotype in Weight Loss After Bariatric Surgery: A Longitudinal Study.

PURPOSE: To evaluate the influence of vitamin D (VD) concentrations coupled with metabolic phenotypes preoperatively and 6 months after Roux-en-Y gastric bypass (RYGB) on body variables and weight loss. MATERIALS AND METHODS: A longitudinal, retrospective, analytical study comprising 30 adult individuals assessed preoperatively (T0) and 6 months (T1) after undergoing Roux-en-Y gastric bypass. The participants were distributed preoperatively into metabolically healthy obese (MHO) and metabolically unhealthy obese individuals (MUHO) according to the HOMA-IR classification, as well as the adequacy and inadequacy of vitamin D concentrations in the form of 25(OH)D. All participants were assessed for weight, height, body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), visceral adiposity index (VAI), body circularity index (BCI), body adiposity index (BAI), weight loss, and assessment of 25(OH)D and 1,25(OH)2D concentrations using high-performance liquid chromatography with an ultraviolet detector (HPLC-UV). The statistical program used was SPSS version 21. RESULTS: VD adequacy and a healthy phenotype in the preoperative period may play an important role concerning body fat distribution, as the body averages for WHtR (0.020*) and BCI (0.020*) were lower in MHO participants. In comparison, those with VD inadequacy and MUHOs had higher BAI averages (0.000*) in the postoperative period. Furthermore, it is possible that VD inadequacy before and after RYGB, even in the presence of an unhealthy phenotype, may contribute to the increase in VAI values (0.029*) after this surgery. Only those with inadequate VD and MUHOs had higher 25(OH)D concentrations. Besides, this unhealthy phenotype had a greater reduction in BMI in the early postoperative period (p < 0.001). CONCLUSION: This study suggests that VD adequacy and the presence of a healthy phenotype appear to have a positive impact on the reduction of visceral fat in the context of pre- and postoperative obesity. In addition, there was a greater weight reduction in those with VD inadequacy and in MUHO, which suggests that the volumetric dilution effect of VD and catabolism after bariatric surgery is more pronounced in this specific metabolic phenotype.

Educação Interprofissional nos cursos da área da saúde de uma universidade pública / Interprofessional Education in health courses at a public university

RESUMO Visto que a Educação Interprofissional tem sido apontada para a reorientação da formação e do trabalho em saúde, objetivou-se analisar sua inserção nos Projetos Pedagógicos dos Cursos de graduação em saúde de uma universidade pública. Trata-se de uma pesquisa pautada na análise documental, dividida em três etapas: leitura exploratória, pré-análise e análise dos documentos. Todos os documentos dos cursos analisados referem-se ao trabalho em equipe como competência importante para a formação, ainda que façam apenas algumas menções pontuais e específicas à interprofissionalidade. Os documentos não apresentam projetos para a implementação da Educação Interprofissional nos currículos regulares, apenas delegam a inserção da interprofissionalidade à extensão universitária. Assim, observou-se que os projetos pedagógicos inserem a Educação Interprofissional de forma restrita nos cursos da área da saúde.

ABSTRACT Since Interprofessional Education has been identified as a means of reorientation health training and work, the objective was to analyze its insertion in the pedagogical projects of undergraduate health courses at a public university. This research is based on document analysis, divided into three stages: exploratory reading, pre-analysis and document analysis. All documents of the analyzed courses refers to teamwork as an important skill for training, even though they only make a few punctual and specific mentions of interprofessionality. The documents do not present projects for the implementation of Interprofessional Education in regular curriculum, they just delegate the insertion of interprofessionality to university extension. Thus, it was observed that pedagogical projects include Interprofessional Education in a restricted way in health courses.

In vitro micropropagation and tiliroside production in Paratecoma peroba (Record) Kuhlm, an endemic and endangered Brazilian tree.

In vitro tissue culture can be an alternative method for endangered species propagation, biodiversity conservation and secondary metabolite studies. Paratecoma peroba (Record) Kuhlm. (Bignoniaceae) is an endemic and endangered Brazilian species. This work aimed to establish in vitro morphogenesis and callus induction and to perform a phytochemical analysis of P. peroba callus extract. Higher seed germination (43%) was obtained in Wood Plant Medium culture without activated charcoal (AC). Combination of 5 µM benzyladenine + 10 µM gibberellic acid, without AC, resulted in a higher number of shoots (2 shoots/explant). A callus culture was stabilised from zygotic embryos using 2,4-dichlorophenoxyacetic acid. A callus methanolic extract was used for phytochemical analysis. The isolated substance was identified as tiliroside (kaempferol 3-O-ß-D-(6''-O-E-p-coumaroyl)-glucopyranoside) by NMR and quantified in callus and leaf extracts by HPLC. This study adds to the chemical knowledge of this species and it is the first report of a flavonol in Paratecoma.

Position statement on nutrition therapy for overweight and obesity: nutrition department of the Brazilian association for the study of obesity and metabolic syndrome (ABESO-2022).

Obesity is a chronic disease resulting from multifactorial causes mainly related to lifestyle (sedentary lifestyle, inadequate eating habits) and to other conditions such as genetic, hereditary, psychological, cultural, and ethnic factors. The weight loss process is slow and complex, and involves lifestyle changes with an emphasis on nutritional therapy, physical activity practice, psychological interventions, and pharmacological or surgical treatment. Because the management of obesity is a long-term process, it is essential that the nutritional treatment contributes to the maintenance of the individual's global health. The main diet-related causes associated with excess weight are the high consumption of ultraprocessed foods, which are high in fats, sugars, and have high energy density; increased portion sizes; and low intake of fruits, vegetables, and grains. In addition, some situations negatively interfere with the weight loss process, such as fad diets that involve the belief in superfoods, the use of teas and phytotherapics, or even the avoidance of certain food groups, as has currently been the case for foods that are sources of carbohydrates. Individuals with obesity are often exposed to fad diets and, on a recurring basis, adhere to proposals with promises of quick solutions, which are not supported by the scientific literature. The adoption of a dietary pattern combining foods such as grains, lean meats, low-fat dairy, fruits, and vegetables, associated with an energy deficit, is the nutritional treatment recommended by the main international guidelines. Moreover, an emphasis on behavioral aspects including motivational interviewing and the encouragement for the individual to develop skills will contribute to achieve and maintain a healthy weight. Therefore, this Position Statement was prepared based on the analysis of the main randomized controlled studies and meta-analyses that tested different nutrition interventions for weight loss. Topics in the frontier of knowledge such as gut microbiota, inflammation, and nutritional genomics, as well as the processes involved in weight regain, were included in this document. This Position Statement was prepared by the Nutrition Department of the Brazilian Association for the Study of Obesity and Metabolic Syndrome (ABESO), with the collaboration of dietitians from research and clinical fields with an emphasis on strategies for weight loss.

A pessoa com demência: contributos de enfermagem de reabilitação na promoção da independência funcional / The person with dementia: contributions of rehabilitation nursing in promoting functional independence

Enquadramento: O presente relatório assenta no percurso formativo do Estágio de Natureza Profissional com uma componente de investigação, realizado nos Cuidados de Saúde Primários, e dedicado fundamentalmente aos problemas decorrentes do envelhecimento, sensíveis às competências da prática da Enfermagem de Reabilitação. A idade avança e muitas vezes a presença de doenças crónicas, como a demência e a DPOC, culminam na limitação e na incapacidade da pessoa se manter independente no seu dia-a-dia, fruto de um declínio funcional, desde: perda de força muscular, alteração do padrão da marcha, diminuição da flexibilidade, perda de agilidade, alteração da coordenação sensória-motora, diminuição da mobilidade articular e comprometimento do equilíbrio. Impõem-se assim medidas que promovam a manutenção e, ou, a melhoria da funcionalidade da pessoa idosa no seu contexto de vida, sendo para tal os cuidados de Enfermagem de Reabilitação um recurso importante. Assim, é abordada a reabilitação no âmbito dos Cuidados de Saúde Primários, sintetizando o papel do EEER na comunidade e as áreas de intervenção ao logo do processo formativo. Sendo a demência uma patologia de grande impacto na funcionalidade da pessoa, neste trabalho aprofunda-se esta problemática através da realização de um estudo de investigação. Metodologia: Para responder aos objetivos do estágio recorreu-se à exploração de conceitos e questões através de uma abordagem critico-reflexiva do percurso formativo na busca pelo desenvolvimento de competências, sustentado nas teorias de enfermagem e bibliografia atual. No âmbito da investigação, foi realizado um estudo quase-experimental de grupo único, com o objetivo de avaliar os efeitos de um programa de Reabilitação funcional motora, no utente com demência moderada em contexto domiciliário. A amostra incluiu 18 pessoas, os quais foram alvo de intervenção do EEER durante 10 semanas, com um total de 20 sessões, numa periodicidade de 2 a 3 vezes por semana. Resultados: A realização do ENP, possibilitou o desenvolvimento e adquisição de competências Comuns e Específicas em Enfermagem de Reabilitação e de Mestre. Relativamente ao programa de intervenção, as avaliações realizadas demonstraram indícios de melhoria global da funcionalidade da pessoa, nomeadamente numa maior independência no autocuidado, melhoria da mobilidade e locomoção, aumento da força muscular global, e melhoria do equilíbrio estático e dinâmico, apresentando ganhos em saúde sensíveis aos cuidados do Enfermeiro de Reabilitação. Conclusões: Os cuidados de Enfermagem de Reabilitação podem ser um contributo para a manutenção e mesmo melhoria da capacidade funcional da pessoa com limitações funcionais, mesmo com patologia crónica como a demência.

Framing: This report is based on the formative course of the Professional Internship with a research component, carried out in Primary Health Care, and dedicated fundamentally to the problems arising from aging, sensitive to the capabilities of rehabilitation nursing practice. Age advances and often the presence of chronic diseases, such as dementia and COPD, culminate in the limitation and inability of the person to remain independent in his daily life, resulting from a functional decline, for instance: loss of muscle strength, change in gait pattern, decreased flexibility, loss of agility, alteration of mental-motor coordination, decreased joint mobility and impaired balance. Therefore, measures are needed to promote the maintenance and, or, improvement of the functionality of the senior citizen in their life context, and rehabilitation nursing care is an important resource. Rehabilitation in the scope of Primary Health Care is addressed, synthesizing the role of the EEER in the community and the areas of intervention at the end of the formative process. Since dementia is a pathology of great impact on the person's functionality, this work deepens this problem through the realization of a research study. Methodology: To respond to the objectives of the internship, we used the exploration of concepts and questions through a critical-reflexive approach to the formative path way in the search for the development of capabilities, supported by nursing theories and current bibliography. In the scope of the research, a single-group near-experimental study was conducted with the objective of evaluating the effects of a motor functional rehabilitation program on users with moderate dementia in the home context. The sample included 18 people, who were the target of EEER intervention for 10 weeks, with a total of 20 sessions, at a frequency of 2 to 3 times a week. Results: The performance of the ENP, allowed the development and acquisition of Common and Specific competencies in Rehabilitation and Master Nursing. Regarding the intervention program, the evaluations showed evidence of overall improvement in the person's functionality, namely a greater independence in self-care, improvement of mobility and locomotion, increased overall muscle strength, and improvement of static and dynamic balance, presenting health gains sensitive to the care of rehabilitation nurses. Conclusions: Rehabilitation Nursing care can be a contribution to the maintenance and even improvement of the functional capacity of the person with functional limitations, even with chronic pathology such as dementia.

The Effect of Vitamin D Adequacy on Thyroid Hormones and Inflammatory Markers after Bariatric Surgery.

Vitamin D status affects the clinical and corporal outcomes of postoperative patients who undergo a Roux-en-Y gastric bypass (RYGB). The aim of this study was to evaluate the effect of adequate vitamin D serum concentrations on thyroid hormones, body weight, blood cell count, and inflammation after an RYGB. A prospective observational study was conducted with eighty-eight patients from whom we collected blood samples before and 6 months after surgery to evaluate their levels of 25-hydroxyvitamin D 25(OH)D, thyroid hormones, and their blood cell count. Their body weight, body mass index (BMI), total weight loss, and excess weight loss were also evaluated 6 and 12 months after surgery. After 6 months, 58% of the patients achieved an adequate vitamin D nutritional status. Patients in the adequate group showed a decrease in the concentration of thyroid-stimulating hormone (TSH) (3.01 vs. 2.22 µUI/mL, p = 0.017) with lower concentrations than the inadequate group at 6 months (2.22 vs. 2.84 µUI/mL, p = 0.020). Six months after surgery, the group with vitamin D adequacy showed a significantly lower BMI compared with the inadequate group at 12 months (31.51 vs. 35.04 kg/m2, p = 0.018). An adequate vitamin D nutritional status seems to favor a significant improvement in one's thyroid hormone levels, immune inflammatory profile, and weight loss performance after an RYGB.

Brazilian guide to nutrition in bariatric and metabolic surgery.

PURPOSE: Brazilian nutrition recommendations for bariatric and metabolic surgery aim to provide knowledge, based on scientific evidence, on nutritional practices related to different surgical techniques in the surgical treatment of obesity and metabolic diseases. MATERIALS AND METHODS: A systematic literature search was carried out with the appropriate MeSH terms using Medline/Pubmed/LiLACS and the Cochrane database, with the established criteria being based on the inclusion of articles according to the degree of recommendation and strength of evidence of the Classification of Recommendations, Evaluation, Development, and Evaluation System (GRADE). RESULTS: The recommendations that make up this guide were gathered to assist in the individualized clinical practice of nutritionists in the nutritional management of patients with obesity, including nutritional management in the intragastric balloon; pre and postoperative nutritional treatment and supplementation in bariatric and metabolic surgeries (adolescents, adults, elderly, pregnant women, and vegetarians); hypoglycemia and reactive hyperinsulinemia; and recurrence of obesity, gut microbiota, and inflammatory bowel diseases. CONCLUSION: We believe that this guide of recommendations will play a decisive role in the clinical practice of nutritionists who work in bariatric and metabolic surgery, with its implementation in health services, thus promoting quality and safety in the treatment of patients with obesity. The concept of precision nutrition is expected to change the way we understand and treat these patients.

Evaluation of Liver Metabolism Biomarkers in Metabolic Associated Fatty Liver Disease According to Obesity Phenotype.

OBJECTIVE: To analyze the relationship between the biochemical markers of liver metabolism in different stages of Metabolic Associated Fatty Liver Disease (MAFLD) according to the obesity phenotype. METHODOLOGY: This is a cross-sectional study with individuals with class III obesity classified according to the obesity phenotypes proposed by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. Biochemical and anthropometric variables were analyzed according to the staging of MAFLD and obesity phenotype. RESULTS: A total of 50 subjects with MAFLD, 62% (n = 31) with steatosis and 38% (n = 19) with steatohepatitis without fibrosis; 36% were classified as metabolically healthy obesity (MHO) and 64% as metabolically unhealthy obesity (MUHO), respectively. Mean values of alkaline phosphatase were 85.44 ± 27.27 vs. 61.92 ± 17.57 (p = 0.006); gamma-glutamyl transpeptidase, 25.77 ± 15.36 vs. 30.63 ± 19.49 (p = 0.025); and albumin, 3.99 ± 0.34 vs. 4.24 ± 0.23 (p = 0.037), were lower and statistically significant in the MHO group with steatosis. The results show when considering individuals with IR, only AP is a predictor of unhealthy phenotype (B-0.934, 0.848- 1.029, p = 0.031). CONCLUSION: MHO individuals with steatosis present lower severe changes related to markers of liver damage and function and AP is considered the predictor of MUHO phenotype.

Intervenções de enfermagem de ajuda na sobrecarga do cuidador informal que cuida da pessoa idosa no domicílio / Nursing interventions to help with the burden of the informal caregiver who takes care of the elderly person at home

Devido ao envelhecimento populacional muitas famílias experienciam ao longo do seu ciclo vital a situação de doença sendo confrontados com um novo papel: ser cuidador. A manutenção da pessoa idosa que necessita de cuidados no domicílio é cada vez mais uma estratégia fundamental que permite a promoção da autonomia e da dignidade dos idosos, no entanto a prestação destes cuidados pode ser extremamente desgastante e, normalmente, acarreta um aumento da sobrecarga por parte de quem os presta. O reconhecimento da importância social dos cuidadores informais faz-se acompanhar de uma atenção aos seus problemas e da procura de respostas para as suas necessidades, na lógica que é preciso "cuidar de quem cuida". Entende-se que são importantes as ações que visem minimizar o impacto da situação de cuidar do familiar idoso, amenizar a intensidade e a diversidade de sentimentos que surgem durante o desempenho deste complexo papel. Neste campo, os enfermeiros especialistas têm um papel fundamental no diagnóstico das diversas necessidades identificadas junto dos cuidados informais, isto é, das principais dificuldades, do nível de conhecimento assim como da sobrecarga. Com isto é possível a definição de estratégias e implementação de intervenções capazes de ajudar no bem-estar dos cuidadores informais e desta forma fomentar uma maior segurança nos cuidados prestados por estes à pessoa idosa no domicílio. Desta forma, o presente relatório apresenta, de forma crítica, reflexiva e introspetiva, o percurso de aquisição e desenvolvimento de competências de enfermeira especialista em Enfermagem Médico-Cirúrgica, conduzidos por objetivos e atividades delineadas com esse propósito. Destacam-se as intervenções realizadas junto aos cuidadores, intervenções essas individuais, dado que os cuidadores são um grupo heterogéneo com diferentes necessidades, expectativas e características. A aquisição de competências de enfermeiro especialista em Enfermagem Médico-Cirúrgica visa o desenvolvimento de conhecimentos e competências específicas, que devem ser mobilizados para a prática, permitindo o desenvolvimento de novos e atualizados comportamentos e habilidades para a prática de Enfermagem.

Due to population aging, many families experience illness throughout their life, being faced with a new role: being a caregiver. The maintenance of the elderly who need care at home is increasingly a fundamental strategy that allows the advancement of autonomy and dignity of the elderly, however, the provision of this care can be extremely exhausting and, normally, it entails an increase in the burden on the part of those who exercise them. Recognition of the social importance of informal caregivers is accompanied by attention to their problems and the search for answers to their needs, in the logic that it is necessary to "help those who help". It is understood that actions aimed at minimizing the impact of the situation of caring for the elderly family member and softening the intensity and diversity of feelings that arise during the performance of this complex role are important. In this field, specialist nurses play a fundamental role in the diagnosis of the many needs identified with informal care, i.e. the main difficulties, knowledge level as well as overload. With this, it is possible to define strategies and implement interventions capable of helping informal caregivers in regards to their well-being and thus foster greater security in the care provided by these to the elderly person at home. In this way, this report makes it possible to demonstrate, in a critical, reflective, and introspective way, the path of acquisition and development of specialist nursing skills in Medical-Surgical Nursing, driven by objectives and activities designed for that purpose. This document describes individual interventions carried out with the caregivers, given that these caregivers are a heterogeneous group with different needs, expectations and characteristics. The acquisition of skills as a specialist nurse in Medical-Surgical Nursing aims to develop specific knowledge and skills, which must be mobilized for practice, allowing the development of new and updated behaviors and skills for nursing practice.

Impairment of Vitamin D Nutritional Status and Metabolic Profile Are Associated with Worsening of Obesity According to the Edmonton Obesity Staging System.

Obesity is associated with a higher risk of Vitamin D (VD) inadequacy and metabolic diseases. The Edmonton Obesity Staging System (EOSS) is an innovative tool for the evaluation of obesity that goes beyond body weight and considers clinic, functional and menta- health issues. This study aimed to evaluate the nutritional status of VD according to the stages of EOSS and its relationship with the metabolic profile. In the cross-sectional study, we evaluated anthropometric parameters, physical activity, blood pressure, biochemical and metabolic variables, and VD nutritional status. A total of 226 individuals were categorized using EOSS: 1.3%, 22.1%, 62.9%, and 13.7% were in stages 0, 1, 2 and 3, respectively. Regarding the metabolic changes and comorbidities, insulin resistance and hyperuricemia were diagnosed in some individuals in EOSS 1, 2, and 3. EOSS 2 and 3 presented a significant relative-risk for the development of arterial hypertension, metabolic syndrome, and liver disease, compared with EOSS 0. In all stages, there were observed means of 25(OH)D serum concentrations below 30 ng/mL (EOSS 0 24.9 ± 3.3 ng/mL; EOSS 3 15.9 ± 5.4 ng/mL; p = 0.031), and 25(OH)D deficiency was present in all stages. Individuals with obesity classified in more advanced stages of EOSS had lower serum concentrations of 25(OH)D and a worse metabolic profile.

Vitamin D Supplementation and Its Relationship with Loss of Visceral Adiposity.

PURPOSE: An inverse relationship between vitamin D (VD) nutritional status and obesity is frequent, and the distribution of body fat is an important aspect to assess the risks of obesity-related metabolic dysfunction. The purpose of the study was to evaluate the relationship between serum VD concentrations and body fat reduction after 12 months of bariatric surgery, using two different vitamin D3 (VD3) supplementation protocols. MATERIAL AND METHODS: A randomized controlled trial consisted of 41 patients divided into G1 (800 IU/day) and G2 (1800 IU/day) according to the VD3 supplementation. At baseline (T0) and follow-up (T1), 25(OH)D, waist circumference (WC), visceral adiposity index (VAI), body adiposity index (BAI), and waist/height ratio (WHtR) were evaluated. RESULTS: In T0, the mean of 25(OH)D was lower in G2 compared to that in G1 (22.6 vs 23.6 ng/mL; p = 0.000). At T1, it had a significant increase in G2 (32.1 vs 29.9 ng/mL; p = 0.000), with 60% sufficiency. A significant negative correlation was observed between VAI, BAI, and WHtR with 25(OH)D in G2 (r = - 0.746, p = 0.024; r = - 0.411, p = 0.036; r = - 0.441, p = 0.032) after surgery. Higher mean changes from baseline of visceral fat loss, represented by VAI, were observed in G2 (176.2 ± 149.0-75.5 ± 55.0, p = 0.000). CONCLUSION: Patients submitted to the 1800 IU/day protocol, 12 months after the surgical procedure, had a higher percentage of sufficient vitamin D levels compared to those submitted to the 800 IU/day protocol. Additionally, higher dose supplementation promoted a significant improvement in VAI.

Adequacy and Vitamin D in the Preoperative Period of Roux-en-Y Gastric Bypass, Bariatric Surgery, Can Protect Metabolic Health in Metabolically Healthy and Unhealthy Individuals.

Evaluating the influence of vitamin D concentrations together with preoperative metabolic phenotypes on remission of chronic noncommunicable diseases (CNCDs) after 6 months of Roux-en-Y gastric bypass (RYGB). Cross-sectional analytical study comprising 30 adult individuals who were assessed preoperatively (T0) and 6 months (T1) after undergoing RYGB. Participants were distributed preoperatively into metabolically healthy obese (MHO) and metabolically unhealthy obese (MUHO) individuals according to HOMA-IR classification and to the adequacy and inadequacy of vitamin D concentrations in the form of 25(OH)D. All participants were assessed for anthropometric characteristics, biochemical variables, and presence of CNCDs. The statistical program used was the SPSS version 21. In face of vitamin D adequacy and regardless of the metabolic phenotype classification in the preoperative period, the means found for HOMA-IR allowed us to define them as metabolically healthy 6 months after RYGB. Only those with vitamin D inadequacy with the MUHO phenotype showed better results regarding the reduction of glucose that accompanied the shift in serum 25(OH)D concentrations from deficient to insufficient. It is possible that preoperative vitamin D adequacy, even in the presence of an unhealthy phenotype, may contribute to the reduction of dyslipidemia and improvement in cholesterol. It is suggested that preoperative vitamin D adequacy in both phenotypes may have a protective effect on metabolic health.

[Conceptions in dispute in the use of micronutrient supplementation and/or fortification in school programs for prevention of anemia]. / Concepções em disputa no uso da suplementação e/ou fortificação de micronutrientes na alimentação escolar para prevenção da anemia.

Iron deficiency anemia affects different populations worldwide, and in Brazil it is one of the principal childhood nutritional deficiencies. Different strategies have been proposed by international agencies and the Brazilian Ministry of Health for its prevention. The study aimed to analyze the ideas in dispute, expressed in official documents and narratives by health and education workers concerning the use of nutritional supplementation and/or fortification as a measure in schools to prevent anemia. The study was based on government documents and semi-structured interviews with workers in municipalities that implemented the school food fortification strategy (NutriSUS) in the state of Rio de Janeiro. The ideas expressed in the government documents highlight the efficiency of home supplementation and fortification for prevention of anemia, based on scientific studies and adjusted to the objectives of the public policies set out in them. Some ideas in the workers' narratives are critical of the need for this type of intervention, others they favor them, indicating controversies in the process of local operationalization of federal policies. Tensions were observed in the concepts of promotion, prevention, and treatment through NutriSUS, dosage, and form of administration. Criticisms of supplementation highlight healthy eating practices as the best strategy. Medicalization rather than health promotion measures can strain the pedagogical perspective in schools and produce contradictory ideas on the best strategies for the promotion of healthy eating.

A anemia por deficiência de ferro afeta, mundialmente, diferentes populações e, no Brasil, é uma das principais carências nutricionais na infância. Diferentes estratégias são propostas por organismos internacionais e pelo Ministério da Saúde para sua prevenção. O objetivo do estudo foi analisar as ideias em disputa, presentes em documentos oficiais e narrativas dos profissionais da saúde e educação acerca do uso da suplementação e/ou fortificação nutricional como medida de prevenção da anemia no âmbito escolar. Baseou-se na análise de documentos governamentais e entrevistas semiestruturadas com profissionais atuantes em municípios que implementaram a estratégia de fortificação da alimentação escolar (NutriSUS) no Estado do Rio de Janeiro. As ideias disseminadas nos documentos governamentais ressaltam a eficiência da suplementação e da fortificação caseira para prevenção de anemia, com base em pesquisas científicas e se adequa aos objetivos das políticas públicas neles formalizados. As ideias presentes nas narrativas dos profissionais são, por vezes, críticas à necessidade desse tipo de intervenção e, por outras, favoráveis, indicando as controvérsias presentes no próprio processo de operacionalização local das políticas federais. Observaram-se tensões em torno dos conceitos de promoção, prevenção e tratamento por meio do NutriSUS, da dosagem e da forma de administração. As críticas à suplementação ressaltam as práticas alimentares saudáveis como estratégia preferencial. A medicalização em detrimento de ações de promoção da saúde pode tencionar a perspectiva pedagógica no contexto escolar e produzir ideias contraditórias sobre as melhores estratégias de promoção de alimentação saudável.

La anemia por deficiencia de hierro afecta mundialmente a diferentes poblaciones y, en Brasil, es una de las principales carencias nutricionales durante la infancia. Se proponen diferentes estrategias por parte de organismos internacionales y el Ministerio de Salud para su prevención. El objetivo del estudio fue analizar las ideas en disputa, presentes en documentos oficiales y narraciones de los profesionales de salud y educación, acerca del uso de los suplementos y/o enriquecimientos nutricionales, como medida de prevención de la anemia en el ámbito escolar. Se basó en el análisis de documentos gubernamentales y entrevistas semiestructuradas con profesionales que actuaban en municipios que implementaron la estrategia de fortificación de la alimentación escolar (NutriSUS) en el estado de Río de Janeiro. Las ideas difundidas en los documentos gubernamentales resaltan la eficiencia de la suplementación y del enriquecimiento alimenticio casero para la prevención de anemia, basadas investigaciones científicas, y se adecua a los objetivos de las políticas públicas en ellos formalizados. Las ideas presentes en las narraciones de los profesionales son, a veces, críticas con la necesidad de este tipo de intervención y, otras veces, favorables, indicando las controversias presentes en el propio proceso de operacionalización local de las políticas federales. Se observaron tensiones en torno a los conceptos de promoción, prevención y tratamiento mediante NutriSUS, así como sobre la dosificación y la forma de administración. Las críticas a los suplementos resaltan las prácticas alimentarias saludables como estrategia preferente. La medicalización en detrimento de acciones de promoción de la salud puede tensionar la perspectiva pedagógica en el contexto escolar y producir ideas contradictorias sobre las mejores estrategias de promoción de alimentación saludable.

Body Composition, Basal Metabolic Rate and Leptin in Long-Term Weight Regain After Roux-en-Y Gastric Bypass Are Similar to Pre-surgical Obesity.

PURPOSE: The purpose of this study is to evaluate the relationship between body composition, basal metabolic rate (BMR), and serum concentrations of leptin with long-term weight regain after Roux-en-Y gastric bypass (RYGB) and compare it with obesity before surgery. MATERIALS AND METHODS: Prospective longitudinal analytical study. Three groups were formed: individuals 60 months post RYGB, with weight regain (G1) and without it (G2), and individuals with obesity who had not undergone bariatric surgery (G3). Body fat (BF), body fat mass (BFM), visceral fat (VF), fat-free mass (FFM), skeletal muscle mass (SMM), and BMR were assessed by octapolar and multi-frequency electrical bioimpedance. Fasting serum concentrations of leptin were measured. RESULTS: Seventy-two individuals were included, 24 in each group. Higher means of BF, BFM, VF, and leptin levels were observed in G1, when compared to G2 (BF: 47.5 ± 5.6 vs. 32.0 ± 8.0, p < 0.05; FBM: 47.8 ± 11.6 vs. 23.9 ± 7.0, p < 0.05; VF: 156.8 ± 30.2 vs. 96.1 ± 23.8, p < 0.05; leptin: 45,251.2 pg/mL ± 20,071.8 vs. 11,525.7 pg/mL ± 9177.5, p < 0.000). G1 and G2 did not differ in FFM, SMM, and BMR. G1 and G3 were similar according to BF, FFM, BMR, and leptin levels. Body composition, but not leptin, was correlated with %weight regain in G1 (FBM: r = 0.666, p < 0.000; BF: r = 0.428, p = 0.037; VF: r = 0.544, p = 0.006). CONCLUSION: Long-term weight regain after RYGB is similar to pre-surgical obesity in body composition, BMR, and leptin concentrations, indicating relapse of metabolic and hormonal impairments associated with excessive body fat.

Inadequacy of Vitamin D Does Not Interfere with Body Weight Loss in Women of Reproductive Age after Roux-en-Y Gastric Bypass.

Objective: To assess the influence of vitamin D on body weight loss in women who had previously undergone Roux-en-Y gastric bypass (RYGB). Methodology: This is an analytical, longitudinal and retrospective study comprising 40 women of reproductive age who had previously undergone RYGB. To investigate the influence of the serum concentrations of vitamin D on body weight reduction, the variables were analyzed in the pre-operative period (T0), in the first (T1) and in the second postoperative year (T2) and were stratified according to the BMI measured in T1 and T2. In addition, in the pre-operative period, participants were subdivided into groups based on adequacy (G1), deficiency (G2) and insufficiency (G3), according to their serum concentrations of vitamin D. Results: Although weight loss occurred in a substantial way in T1, it continued to decrease in T2 (p = 0.017). The women who reached normal weight within two years of surgery showed the lowest vitamin D concentrations preoperatively when compared to those who were overweight (p = 0.011). Women with preoperative vitamin D deficiency showed increased concentrations in the assessed times (p < 0.001), while the opposite (p = 0.001) occurred in women with adequacy. Conclusion: The study showed that inadequacy of vitamin D does not interfere with weight loss in the two-year-follow-up after RYGB and highlights that vitamin D can present a differentiated response postoperatively, to the detriment of the pre-operative period.

Resumo: A anemia por deficiência de ferro afeta, mundialmente, diferentes populações e, no Brasil, é uma das principais carências nutricionais na infância. Diferentes estratégias são propostas por organismos internacionais e pelo Ministério da Saúde para sua prevenção. O objetivo do estudo foi analisar as ideias em disputa, presentes em documentos oficiais e narrativas dos profissionais da saúde e educação acerca do uso da suplementação e/ou fortificação nutricional como medida de prevenção da anemia no âmbito escolar. Baseou-se na análise de documentos governamentais e entrevistas semiestruturadas com profissionais atuantes em municípios que implementaram a estratégia de fortificação da alimentação escolar (NutriSUS) no Estado do Rio de Janeiro. As ideias disseminadas nos documentos governamentais ressaltam a eficiência da suplementação e da fortificação caseira para prevenção de anemia, com base em pesquisas científicas e se adequa aos objetivos das políticas públicas neles formalizados. As ideias presentes nas narrativas dos profissionais são, por vezes, críticas à necessidade desse tipo de intervenção e, por outras, favoráveis, indicando as controvérsias presentes no próprio processo de operacionalização local das políticas federais. Observaram-se tensões em torno dos conceitos de promoção, prevenção e tratamento por meio do NutriSUS, da dosagem e da forma de administração. As críticas à suplementação ressaltam as práticas alimentares saudáveis como estratégia preferencial. A medicalização em detrimento de ações de promoção da saúde pode tencionar a perspectiva pedagógica no contexto escolar e produzir ideias contraditórias sobre as melhores estratégias de promoção de alimentação saudável.

Abstract: Iron deficiency anemia affects different populations worldwide, and in Brazil it is one of the principal childhood nutritional deficiencies. Different strategies have been proposed by international agencies and the Brazilian Ministry of Health for its prevention. The study aimed to analyze the ideas in dispute, expressed in official documents and narratives by health and education workers concerning the use of nutritional supplementation and/or fortification as a measure in schools to prevent anemia. The study was based on government documents and semi-structured interviews with workers in municipalities that implemented the school food fortification strategy (NutriSUS) in the state of Rio de Janeiro. The ideas expressed in the government documents highlight the efficiency of home supplementation and fortification for prevention of anemia, based on scientific studies and adjusted to the objectives of the public policies set out in them. Some ideas in the workers' narratives are critical of the need for this type of intervention, others they favor them, indicating controversies in the process of local operationalization of federal policies. Tensions were observed in the concepts of promotion, prevention, and treatment through NutriSUS, dosage, and form of administration. Criticisms of supplementation highlight healthy eating practices as the best strategy. Medicalization rather than health promotion measures can strain the pedagogical perspective in schools and produce contradictory ideas on the best strategies for the promotion of healthy eating.

Resumen: La anemia por deficiencia de hierro afecta mundialmente a diferentes poblaciones y, en Brasil, es una de las principales carencias nutricionales durante la infancia. Se proponen diferentes estrategias por parte de organismos internacionales y el Ministerio de Salud para su prevención. El objetivo del estudio fue analizar las ideas en disputa, presentes en documentos oficiales y narraciones de los profesionales de salud y educación, acerca del uso de los suplementos y/o enriquecimientos nutricionales, como medida de prevención de la anemia en el ámbito escolar. Se basó en el análisis de documentos gubernamentales y entrevistas semiestructuradas con profesionales que actuaban en municipios que implementaron la estrategia de fortificación de la alimentación escolar (NutriSUS) en el estado de Río de Janeiro. Las ideas difundidas en los documentos gubernamentales resaltan la eficiencia de la suplementación y del enriquecimiento alimenticio casero para la prevención de anemia, basadas investigaciones científicas, y se adecua a los objetivos de las políticas públicas en ellos formalizados. Las ideas presentes en las narraciones de los profesionales son, a veces, críticas con la necesidad de este tipo de intervención y, otras veces, favorables, indicando las controversias presentes en el propio proceso de operacionalización local de las políticas federales. Se observaron tensiones en torno a los conceptos de promoción, prevención y tratamiento mediante NutriSUS, así como sobre la dosificación y la forma de administración. Las críticas a los suplementos resaltan las prácticas alimentarias saludables como estrategia preferente. La medicalización en detrimento de acciones de promoción de la salud puede tensionar la perspectiva pedagógica en el contexto escolar y producir ideas contradictorias sobre las mejores estrategias de promoción de alimentación saludable.

Evaluation of an immunochromatographic test for the detection of glutamate dehydrogenase for the diagnosis of Clostridioides (Clostridium) difficile infection in dogs.

This study aimed to evaluate an immunochromatographic test used to detect glutamate dehydrogenase (GDH) for the diagnosis of Clostridium difficile infection (CDI) in dogs. Fecal samples of 119 diarrheic dogs were subjected to toxigenic culture as the "gold standard" method and to GDH detection (Ecodiagnostica, Brazil). Samples positive for toxigenic C. difficile strains and those positive in the GDH test were also subjected to A/B toxin detection using an enzyme immunoassay kit (C. difficile Tox A/B II, Techlab Inc., USA). Sensitivity, specificity, and positive and negative predictive values (PPV and NPV, respectively) were measured for GDH detection and compared with the toxigenic culture results. A total of 19 (15.9%) dogs were positive for toxigenic C. difficile. Of these, 10 (52.6%) dogs were positive for A/B toxins using the enzyme immunoassay kit and 18 (15.2%) were positive in the GDH test, leading to a sensitivity and NPV of 89.4% and 97.9%, respectively. Three animals, two of which were colonized with non-toxigenic strains, were positive for GDH, though not confirmed with CDI, resulting in a high specificity (97%) and PPV (85%). The results suggest that the lateral flow test for GDH detection could be a useful method for diagnosing CDI in dogs, similar to that previously described for humans and other animal species.

Enteric Organisms Detected in Feces of Dogs With Bloody Diarrhea: 45 Cases.

Bloody diarrhea is a common condition in dogs, but studies evaluating the enteropathogens involved specifically in adult dogs are scarce. In the present study, stool samples from 45 adult dogs with bloody diarrhea were evaluated for the four enteric organisms mainly reported in these cases: canine parvovirus type 2 (CPV-2), Clostridioides difficile, Clostridium perfringens, and Salmonella spp. In addition, the samples were also tested for coronavirus, rotavirus, Giardia spp., and Escherichia coli pathotypes to provide a better understanding of possible co-occurrence. Vaccination status, diet, and clinical outcome were also obtained when available. CPV-2b was identified in 17 dogs (37.8%), being the most frequent cause of bloody diarrhea, including completely vaccinated adult dogs. Toxigenic C. difficile and C. perfringens netF+ were detected in 6 (13.3%) and 5 (11.1%) dogs, in some cases in a co-occurrence with other enteric organisms. Three fatal cases of salmonellosis were identified in dogs fed a raw meat-based diet, raising the risks associated with this increasing practice.

Deficiência e transferência de renda diante da síndrome congênita do Zika vírus: um estudo sobre a Medida Provisória 894/2019 / Discapacidad y transferencia de renta ante el síndrome congénito del zika virus: un estudio sobre la medida provisional 894/2019 / Disability and income transfer in relation to congenital Zika syndrome: a study of provisional measure 894/2019

Desde 2015, a Síndrome Congênita do Zika Vírus (SCZV) marca o cenário brasileiro, extrapolando o campo da Saúde Pública com demandas da proteção social. Considerando a intersecção entre pobreza, deficiência e marcos da seguridade social, examina-se a Medida Provisória 894, que prevê renda mensal vitalícia para as crianças acometidas. Com o objetivo discutir o instrumento à luz dos marcos da seguridade social no recorte da transferência de renda não condicionada para as pessoas com deficiência (PcD) no Brasil, realizou-se um estudo qualitativo mediante análise de documentos públicos e revisão de literatura. As respostas estatais não produziram impacto na insuficiência de renda porque voltaram-se inicialmente para atender à situação emergencial, recorrendo às políticas preexistentes, e culminaram na substituição entre modalidades de transferência de renda - o Benefício de Prestação Continuada para Pensão Vitalícia -, revelando fragilização da proteção social integral.

Since 2015, Congenital Zika Syndrome (CZS) has been a feature of the Brazilian context and has moved beyond public health to demands for social protection. Given the intersection between poverty, disability and the social security framework, we examine Provisional Measure 894, which provides a lifetime monthly income for affected children. We conduct a qualitative study, analysing public documents and reviewing the literature, in order to discuss this instrument in the light of social security frameworks for unconditional cash transfers for People with Disabilities (PwD) in Brazil. State responses did not have an impact on income insufficiencies, since they were initially intended to respond to emergency situations and referred to pre-existing policies; this culminated in an income transfer modality, the Continuous Cash Benefit, being replaced by a Lifetime Pension, demonstrating a weakening of comprehensive social protection.
