Patient education program for Brazilians living with diabetes and prediabetes: findings from a development study.

BACKGROUND: Globally, the incidence of diabetes is increasing and strategies to reach a comprehensive approach of care are needed, including education in self-management. This is particularly true in low and middle-income countries where the number of people living with diabetes is higher than in the high-income ones. This article describes the development of a structured patient education program for Brazilians living with diabetes or prediabetes. METHODS: These steps were undertaken: 1) a 4-phase needs assessment (literature search of local diabetes guidelines, environmental scan, evaluation of information needs of patients identified by diabetes experts, and patient focus groups); and, 2) the translation and cultural adaptation of the patient guide (preparation, translation, back-translation, back-translation review, harmonization, and proofreading). RESULTS: Four of the seven guidelines identified include educational aspects of diabetes management. No structured education program was reported from the environmental scan. Regarding the information needs, 15 diabetes experts identified their patients' needs, who referred that they have high information needs for topics related to their health condition. Finally, results from six patient focus groups were clustered into six themes (self-management, physical activity, eating habits, diabetes medication, psychosocial being, and sleep), all embedded into the new education program. Constructive theory, adult learning principles, and the Health Action Process Approach model were used in program development and will be used in delivery. The developed program consists of 18 educational sessions strategically mapped and sequenced to support the program learning outcomes and a patient guide with 17 chapters organized into five sections, matched with weekly lectures. CONCLUSIONS: This program is a sequential and theoretical strategic intervention that can reach programs in Brazil to support diabetes and prediabetes patient education.

Severe osteoporosis in a young man with bilateral Cushing's syndrome: a case report.

BACKGROUND: The diagnosis of Cushing's syndrome is challenging; however, through the clinical picture and the search for secondary causes of osteoporosis, it was possible to reach the diagnosis of the case reported. There was an independent, symptomatic ACTH hypercortisolism manifested by typical phenotypic changes, severe secondary osteoporosis and arterial hypertension in a young patient. CASE PRESENTATION: A 20-year-old Brazilian man with low back pain for 8 months. Radiographs showed fragility fractures in the thoracolumbar spine, and bone densitometry showed osteoporosis, especially when evaluating the Z Score (- 5.6 in the lumbar spine). On physical examination, there were wide violaceous streaks on the upper limbs and abdomen, plethora and fat increase in the temporal facial region, hump, ecchymosis on limbs, hypotrophy of arms and thighs, central obesity and kyphoscoliosis. His blood pressure was 150 × 90 mmHg. Cortisol after 1 mg of dexamethasone (24.1 µg/dL) and after Liddle 1 (28 µg/dL) were not suppressed, despite normal cortisoluria. Tomography showed bilateral adrenal nodules with more severe characteristics. Unfortunately, through the catheterization of adrenal veins, it was not possible to differentiate the nodules due to the achievement of cortisol levels that exceeded the upper limit of the dilution method. Among the hypotheses for the differential diagnosis of bilateral adrenal hyperplasia are primary bilateral macronodular adrenal hyperplasia, McCune-Albright syndrome and isolated bilateral primary pigmented nodular hyperplasia or associated with Carney's complex. In this case, primary pigmented nodular hyperplasia or carcinoma became important etiological hypotheses when comparing the epidemiology in a young man and the clinical-laboratory-imaging findings of the differential diagnoses. After 6 months of drug inhibition of steroidogenesis, blood pressure control and anti-osteoporotic therapy, the levels and deleterious metabolic effects of hypercortisolism, which could also impair adrenalectomy in the short and long term, were reduced. Left adrenalectomy was chosen, given the possibility of malignancy in a young patient and to avoid unnecessary definitive surgical adrenal insufficiency if the adrenalectomy was bilateral. Anatomopathology of the left gland revealed expansion of the zona fasciculate with multiple nonencapsulated nodules. CONCLUSION: The early identification of Cushing's syndrome, with measures based on the assessment of risks and benefits, remains the best way to prevent its progression and reduce the morbidity of the condition. Despite the unavailability of genetic analysis for a precise etiological definition, it is possible to take efficient measures to avoid future damage.

Impact of an educational intervention in the management of individuals with uncontrolled type 2 diabetes mellitus using insulin therapy.

OBJECTIVE: To investigate the effects of problematizing intervention in the treatment of individuals with type 2 diabetes mellitus. METHODOLOGY: A randomized clinical trial was conducted in 41 patients ages 18 to 64 with type 2 diabetes who were treated with insulin and had glycosylated hemoglobin greater than 7.0%. The mean age of participants was 55.9 (SD = 5.49). A high percentage of patients had comorbidities such as hypertension (92.7%), dyslipidemia (68.3%), overweight (95%), retinopathy (41%), and neuropathy (39%). The patients in the intervention group participated in 6 educational groups using problematization methodology, whereas the patients in the control group attended only routine consultations. Sociodemographic, clinical, behavioral, and lifestyle variables were assessed. RESULTS: After 6 months of follow-up, no statistically significant difference in glycemic control and anthropometric parameters was observed between participants in either study group. The intervention group showed an increase in knowledge about the disease, and an improvement in total cholesterol and uric acid levels. CONCLUSION: The use of a problematizing intervention provided an improvement in behavioral as well as specific clinical parameters, compared to routine diabetes care. However, longer follow-up time for these patients could bring benefits regarding glycemic control.

Cross-sectional assessment of mild cognitive impairment in pre-dialysis chronic kidney disease and its association with inflammation and changes seen on MRI: what the eyes cannot see.

INTRODUCTION: Mild cognitive impairment (MCI) is a prevalent and underdiagnosed condition in chronic kidney disease (CKD), that shares common pathophysiological factors such as chronic inflammation. OBJECTIVE: To evaluate the association of MCI in CKD stages 1-5 using inflammatory markers and changes by magnetic resonance imaging (MRI). PATIENTS AND METHODS: Cross-sectional study in adult patients with pre-dialysis CKD. MCI was assessed by the Montreal Cognitive Assessment (MoCA) and the estimated glomerular filtration rate (eGFR) by the Chronic Kidney Disease Epidemiology Collaboration equation. Sociodemographic and clinical data were collected from medical records. The cytokines IL-4, IL-6, IL-17, TNF-α and hs-CRP were determined. Brain MRI was performed in a 1.5 Tesla device, without paramagnetic contrast. A descriptive analysis followed by a comparison of abnormal versus normal MoCA scores among all studied variables. A linear regression analysis was performed using MoCA as a dependent variable, adjusted for confounding factors. RESULTS: Of 111 invited patients, eighty completed the neuropsychological assessment and 56 underwent MRI, and were included in the study. Mean age was 56.3 ± 8.3 years and 51.8% (n = 29) had altered MoCA. When compared to the group with normal MoCA, the group with altered MoCA had higher levels of IL-6 and IL-17. There was no correlation between altered MoCA with eGFR or with MRI abnormalities. CONCLUSÃO: MCI assessed by MoCA was prevalent in patients with pre-dialysis CKD, it was associated with inflammation and showed no correlation with MRI changes.

Translation, cross-cultural adaptation, and psychometric properties of the Brazilian Portuguese version of the DiAbeTes Education Questionnaire (DATE-Q).

BACKGROUND: The DiAbeTes Education Questionnaire (DATE-Q) is a self-administered tool developed to evaluate disease-related knowledge and to assess knowledge of five core components of rehabilitation programs: physical exercise, diet, psychosocial well-being, disease self-management, and complications. OBJECTIVE: To translate and cross-culturally adapt into Brazilian Portuguese, and to test the psychometric properties of the DATE-Q for its use in Brazil. METHODS: The process of translation and cross-cultural adaptation consisted of five steps: translation into Brazilian Portuguese, synthesis of translation, back translation, expert committee, and pilot test of pre-final version. The pre-final version was applied to a sample of 30 patients with diabetes. Psychometric properties (internal consistency, reliability, construct validity, and ceiling and floor effects) of the final version of the Brazilian Portuguese version of the DATE-Q were tested in a sample of 200 adults with diabetes. RESULTS: There was no conceptual divergence between the original and the translated versions. Ten (50%) items of the DATE-Q were culturally adapted. Internal consistency (Cronbach's alpha coefficient = 0.6), reliability (intraclass correlation coefficient = 0.5), and construct validity (correlation between Diabetes Knowledge Scales and DATE-Q total scores: ρ = 0.7; P < 0.001) were confirmed. Ceiling or floor effects were not identified. The highest scoring item was about healthy eating. The average time for completion of the DATE-Q was 5 min and 51 s, and the completion rate was 100% for all items. CONCLUSION: The Brazilian Portuguese version of the DATE-Q showed adequate psychometric properties, and results suggested that the tool can be used to assess disease-related knowledge in adults with diabetes in Brazil.

Psychometric validation of the Brazilian Portuguese version of Bandura's exercise self-efficacy scale in diabetes patients.

PURPOSE: The management of diabetes comprises diet, pharmacological therapy, lifestyle counseling, patient education, and physical exercising, to achieve change in health behavior and control of the disease. However, a large proportion of diabetes patients does not adhere to treatment recommendations, mainly in the lifestyle aspect, which remains sedentary. Considering that self-efficacy is an essential determinant of health behaviors such as exercise practicing, the objective of the study was to investigate the psychometric properties of the Brazilian Portuguese version of Bandura's Exercise Self-Efficacy Scale (BESES) to be used in diabetes patients. METHODS: The BESES was initially completed by thirty diabetes patients to confirm the feasibility of the answers be provided by themselves. The psychometric properties (i.e., internal consistency, test-retest reproducibility, convergent validity, and ceiling and floor effects) were tested in other two-hundred diabetes patients (≥18 years old). RESULTS: The BESES achieved significant internal consistency (Cronbach's alpha coefficient = 0.92), substantial test-retest reproducibility (intraclass correlation coefficient = 0.83). The convergent validity was confirmed by negative correlations between BESES total scores and barriers to exercise total scores (ρ = -0.333; P = 0.018) and rate of perception exercise corrected by distance covered in the incremental shuttle walking test (ρ = -0.426; P = 0.002). Ceiling and floor effects were not found. In addition, physically active patients had BESES total scores higher compared to sedentary (56.8 ± 21.4 vs. 47.9 ± 20.0; P = 0.003). CONCLUSION: The Brazilian Portuguese version of the BESES showed adequate psychometric properties and proved to be valid for assessing the exercise self-efficacy in diabetes patients in Brazil.

Atypical Presentation of a Medullary Thyroid Carcinoma Producing Acth and Serotonin.

Medullary carcinoma accounts for about 5% of all thyroid malignancies. The tumor may produce other hormones in addition to calcitonin that typically occurs in the presence of distant metastases. The aim of this report is to present a case of invasive medullary thyroid carcinoma producing ACTH and serotonin. A male patient sought medical attention due to facial plethora and distal paresthesia. On thyroid ultrasound, he presented a hypoechoic nodule measuring 6.7 × 3.2 × 3.5 cm, with punctate calcifications and central vascular pattern. The chest computed tomography showed an extensive solid lesion with epicenter in the superior mediastinum and absence of a cleavage plane with the left thyroid lobe. The lesion extended from the glottic area to the lower portion of the trachea and invaded esophagus, posterior tracheal wall, and left jugular. The patient presented hyperglycemia, hypokalemia, increased free urinary cortisol, calcitonin, ACTH and 5-hydroxyindoleacetic acid levels. The nodule cytological examination obtained by fine-needle aspiration was inconclusive, and the open biopsy confirmed the diagnosis of medullary thyroid carcinoma. Due to the advanced disease stage and increased risk of large caliber vessels injury in case of surgery, local chemotherapy and radiotherapy were recommended. With this report, we want to draw attention to an unusual association between advanced medullary thyroid carcinoma with an aggressive course and ectopic production of ACTH and serotonin.

Intradialytic resistance training: an effective and easy-to-execute strategy.

Chronic kidney disease (CKD) alters the morphology and function of skeletal muscles, thereby decreasing patient physical capacity (PC) and quality of life (QoL). Intradialytic resistance training (IRT) is a pragmatic tool used to attenuate these complications. However, IRT has not been strongly adopted in nephrology care centers. This study aimed to assess the efficacy and safety of a low-cost, easy-to-use IRT protocol. METHODS: The study enrolled 43 patients (52.8 ± 13.85 years) on HD for five to 300 months followed from April 2014 to July 2017. The efficacy of IRT was assessed based on PC - derived from muscle strength (MS) and preferred walking speed (PWS) - and QoL. The occurrence of adverse events was used as a measure of safety. The IRT protocol consisted of exercises of moderate to high intensity for the main muscle groups performed three times a week. RESULTS: The mean follow-up time was 9.3 ± 3.24 months, for a total of 4,374 sessions of IRT. Compliance to the protocol was 96.5 ± 2.90%, and patients presented significant improvements in MS (from 27.3 ± 11.58 Kgf to 34.8 ± 10.77 Kgf) and PWS (from 0.99 ± 0.29 m/s to 1.26 ± 0.22 m/s). Physical and emotional components of QoL also increased significantly. CONCLUSION: IRT led to significant increases in PC and higher scores in all domains of QoL. Important adverse events were not observed during intradialytic resistance training.

Resumo Introdução: O comprometimento cognitivo leve (CCL) é prevalente e subdiagnosticado na doença renal crônica (DRC), condição com a qual compartilha fatores fisiopatológicos como a inflamação crônica. Objetivo: Avaliar a associação do CCL na DRC estágios 1 a 5, com marcadores inflamatórios e alterações de exames de imagem por ressonância magnética (RM). Pacientes e métodos: Estudo transversal em pacientes adultos, com DRC pré-dialítica. CCL foi avaliado pelo Montreal Cognitive Assessment (MoCA) e a taxa de filtração glomerular estimada (TFGe), pela equação do CKD-EPI. Dados sociodemográficos e clínicos foram coletados nos prontuários médicos. Dosadas citocinas IL-4, IL-6, IL-17, o TNF-α e PCR-us. A RM do encéfalo foi realizada em aparelho de 1,5 Tesla, sem contraste. Realizada análise descritiva seguida por comparação de pontuações do MoCA anormais versus normais entre todas as variáveis estudadas. A regressão linear foi realizada usando MoCA como uma variável dependente, ajustada para fatores de confusão. Resultados: De 111 pacientes convidados, oitenta completaram a avaliação neuropsicológica, 56 realizaram RM, tendo sido incluídos no estudo. A média de idade foi de 56,3 ± 8,3 anos e 51,8% (n = 29) apresentavam MoCA alterado. Quando comparado ao grupo MoCA normal, o grupo MoCA alterado apresentou níveis mais elevados de IL-6 e IL-17. Não houve correlação entre MoCA alterado com TFGe nem com anormalidades na RM. Nos modelos ajustados, a IL-6 foi preditor independente do MoCA alterado Conclusão: O CCL avaliado pelo MoCA foi prevalente em pacientes com DRC pré-dialítica, associou-se com inflamação e não apresentou correlação com alterações da RM.

Resumo A doença renal crônica (DRC) promove alterações morfofuncionais dos músculos esqueléticos, gerando redução da capacidade físico-funcional (CF) e pior qualidade de vida (QV). O treinamento resistido intradialítico (TRI) é considerado uma ação pragmática para atenuar tais complicações. Contudo, nota-se baixa inserção do TRI nos centros de tratamento em nefrologia. O objetivo deste estudo foi avaliar a eficácia e a segurança de uma proposta metodológica de TRI de fácil execução e de baixo custo. Métodos: 43 pacientes (52,8±13,85 anos), com tempo em HD entre cinco e 300 meses, foram acompanhados entre abril de 2014 e julho de 2017. A eficácia do TRI foi mensurada pela CF, avaliada pela força muscular (FM) e pela velocidade de caminhada usual (VCU) e pela QV. Como critério de segurança adotou-se a ocorrência de intercorrências clínicas. O protocolo de TRI consistiu em exercícios de moderada a alta intensidade para os principais grupos musculares, realizados três vezes por semana. Resultados: o tempo médio de acompanhamento foi de 9,3 ± 3,24 meses, totalizando 4.374 sessões de TRI. A aderência ao protocolo foi de 96,5 ± 2,90, e os pacientes apresentaram melhora significativa da FM (de 27,3±11,58 Kgf para 34,8±10,77 Kgf) e da VCU (de 0,99 ± 0,29 m/s para 1,26 ± 0,22 m/s). Quanto à QV, tanto os domínios do componente físico quanto do emocional aumentaram significativamente. Conclusão: o TRI promoveu aumento significativo da CF e melhora de todos os domínios da QV, e não foram observadas intercorrências importantes com a realização dos exercícios intradialíticos.

Obesidade: da fisiopatologia ao tratamento / Obesity: from pathophysiology to treatment

O mundo mudou. O Brasil mudou. Nossa população que até meados do século 20 enfrentava o fantasma da desnutrição proteico-calórica agora vive as consequências do ganho excessivo de peso corporal e da obesidade. O sistema de saúde, em nosso país passa então enfrentar a chamada tripla carga de doenças na qual ao lado da desnutrição e das doenças infecciosas crescem as consequências das causas externas e a prevalência das condições crônicas de saúde. Dentre as condições crônicas de saúde, a obesidade se destaca como enfermidade de etiologia multifatorial e complexa, que representa fator de risco importante para uma série de outras doenças de elevada prevalência e relevância clínica, tais como o diabetes mellitus, a hipertensão arterial, as doenças cardiovasculares, a doença renal crônica, a esteatohepatite não alcoólica e certos tipos de cânceres. Dessa forma, o melhor entendimento de sua epidemiologia, fisiopatologia, características clínicas e tratamento podem contribuir para o enfrentamento e a prevenção de uma série de outras doenças de grande impacto sobre a saúde de várias populações. Nesta edição temática da HU Revista, pretendemos abordar vários aspectos relacionados a questões fisiopatológicas e clínicas da obesidade, além de propostas preventivas e terapêuticas, sob a forma de artigos originais, de revisão e relato de experiência. Os artigos foram elaborados por autores de diversas áreas com experiência no estudo da obesidade e de aspectos relacionados a essa doença. Convidamos os leitores a visitar tópicos inusitados e pouco lembrados, como a saúde óssea e risco de fraturas no obeso, e questões relacionadas à etiopatogenia da doença renal relacionada à obesidade. Além disso, será possível revisitar os mecanismos ligados à inflamação e ao risco de diabetes mellitus tipo 2 e se atualizar na abordagem laboratorial, além de ampliar as possibilidades de intervenção terapêutica, seja medicamentosa ou não farmacológica, com revisão detalhada sobre a orientação nutricional e a prescrição de exercício físico. Dentre estas estratégias, destacamos a confecção do guia educativo para prevenção e tratamento do excesso de peso, ferramenta pedagógica que visa orientar e motivar os indivíduos a modificarem hábitos de vida focando em autonomia e atitudes do paciente. Dessa forma, pretendemos contribuir para atualização científica a respeito dessa condição crônica de saúde tão prevalente na prática clínica atual, divulgando informações e contribuindo assim para um enfrentamento potencialmente mais afetivo. Fica aqui o nosso convite!

Desenvolvimento de material educacional interdisciplinar para prevenção e tratamento da obesidade / Educational experience through interdisciplinary intervention in the obesity outpatient clinic in a university hospital

ntrodução: a obesidade é uma doença crônica e complexa de caráter epidêmico, sendo fator de risco para diversas doenças. O município de Juiz de Fora possui uma prevalência maior de obesidade que a da capital do Estado de Minas Gerais e também à média nacional, sendo necessárias estratégias de estímulo às práticas de vida saudáveis, pautadas nas ações educativas em saúde, envolvendo orientação nutricional, prática de atividades físicas, além da abordagem de aspectos biopsicossociais e culturais do indivíduo.Objetivo: desenvolvimento de programa de educação continuada e estímulo ao autocuidado do indivíduo em relação às suas condições de saúde. Relato de experiência: com base nas demandas dos pacientes atendidos nas consultas individuais, grupos operativos e salas de espera, uma cartilha educativa ("Guia de Prevenção ­ Prevenindo e tratando o excesso de peso") foi criada pela equipe multidisciplinar do ambulatório de prevenção e tratamento da obesidade de um hospital universitário. Este material foi lançado oficialmente em setembro de 2018 e tem possibilitado a divulgação de vários temas relacionados à obesidade, como diagnóstico, prevenção e mudança do estilo de vida. Os principais beneficiários desse projeto são os pacientes assistidos nos ambulatórios, contudo poderá auxiliar em ações extra-muros, como atividades em escolas públicas municipais e ações pontuais no campus universitário, por exemplo, no Dia Internacional de Combate à Obesidade. Discussão: o material foi bem aceito e as principais dúvidas após a leitura foram em relação à definição de obesidade e o fato de não reconhecerem a fisiopatologia da doença como uma interação de fatores genéticos e ambientais. Conclusão: ações educativas complementares à prevenção e tratamento da obesidade, envolvendo os vários aspectos do cuidado, têm grande aceitação pela população abordada e representam ferramentas com potencial de melhora do autocuidado e autonomia do indivíduo.

Introduction: obesity is a chronic and complex condition with an epidemic nature, being a risk factor for several diseases. The city of Juiz de Fora has a higher prevalence than the capital of the state of Minas Gerais and also the national average. Strategies are needed to stimulate healthy life practices, based on educational health actions, involving nutritional orientation, practice of activities physical and biopsychosocial aspects of the individual. Objective: to develop a continuing education program and stimulate the individual's self-care in relation to their health conditions. Experience Report: based on the demands of the patients attending the individual consultations, operating groups and waiting rooms, an educational booklet ("Prevention Guide - Preventing and treating excess weight") was created by the multidisciplinary team from the prevention outpatient clinic and treatment of obesity at a university hospital. This material was officially launched in September of 2018 and has made it possible the dissemination of various topics related to obesity, such as diagnosis, prevention and lifestyle change. The main beneficiaries of this project are patients attending the outpatient clinic, but may assist in extra-mural actions, such as activities in some municipal public schools and specific actions on the university campus, for example on the International Day to Combat Obesity. Discussion: the material was well accepted and the main doubts after reading were related to the definition of obesity and the fact that they did not recognize the physiopathology of the disease as an interaction of genetic and environmental factors. Conclusion: educational actions complementary to the prevention and treatment of obesity, involving the various aspects of care, are widely accepted by the population concerned and represent tools with potential for improving self-care and autonomy of the individual.

Obesidade e doença renal: aspectos fisiopatológicos / Obesity and kidney disease: pathophysiological aspects

A epidemia de obesidade observada nas últimas décadas é acompanhada de aumento exponencial de doenças crônicas relacionadas, com destaque diabetes mellitus tipo 2, hipertensão arterial sistêmica, dislipidemia e doenças cardiovasculares. Do mesmo modo, a obesidade constitui fator de risco independente para o desenvolvimento de doença renal crônica, condição associada a elevados índices de morbidade e de mortalidade. A obesidade causa lesão renal de maneira indireta, por meio de sua estreita associação com hipertensão arterial sistêmica e com diabetes mellitus tipo 2 e de maneira direta, ao induzir adaptações glomerulares que culminam na glomerulopatia específica da obesidade. Além disso, o excesso de peso contribui para o agravamento de glomerulopatias pré-existentes. Múltiplos fatores explicam o desenvolvimento e o agravamento das lesões renais associadas à obesidade, em especial alterações hemodinâmicas, inflamatórias e metabólicas. Nesse contexto, a redução do peso corporal com ênfase nas alterações metabólicas e inflamatórias bem como o tratamento da hipertensão arterial e do diabetes mellitus constituem o primeiro passo para a prevenção primária e secundária do desenvolvimento de doença renal crônica. Nesta revisão serão apresentados os principais mecanismos fisiopatológicos da lesão renal associada à obesidade.

n the last decades, the obese epidemic has been accompanied by an exponential increase in the prevalence of chronic conditions such as type 2 diabetes, hypertension, dyslipidemia, and other forms of cardiovascular disease. Moreover, obesity is an independent risk factor for the development of chronic kidney disease, itself a condition associated with high risk of morbidity and mortality. Obesity can cause chronic kidney disease both indirectly, as a major risk factor for diabetes and hypertension, and directly, through adaptive glomerular changes that evolve into a specific form of glomerulopathy. Furthermore, excessive weight can worsen other forms of pre-existent glomerular diseases. Multiple factors can explain the development and worsening of renal lesions associated with obesity, mainly through hemodynamic, inflammatory and metabolic changes. In this context, reduction of body weight with emphasis on metabolic and inflammatory changes, as well as the treatment of hypertension and diabetes, constitute the first step towards primary and secondary prevention against development of chronic kidney disease. This review presents the physiopathology of the obesity related glomerulopathy.

Compulsão alimentar periódica: aspecto negligenciado na abordagem de pacientes com síndrome metabólica / Binge eating: a neglected element in the approach to patients with metabolic syndrome

Introdução: obesidade, um dos principais componentes da síndrome metabólica frequentemente associa-se à compulsão alimentar periódica. Objetivo: o objetivo do presente estudo foi avaliar a presença da compulsão alimentar periódica em mulheres com síndrome metabólica e a possível associação com parâmetros sociodemográficos, clínicos e comportamentais. Material e métodos: estudo transversal com 124 indivíduos com síndrome metabólica, divididos de acordo com presença ou ausência da compulsão alimentar periódica, classificados pela Escala de Compulsão Alimentar Periódica (ECAP). Quantificamos peso, altura, circunferência da cintura e pressão arterial. Avaliamos parâmetros comportamentais: nível de atividade física, consumo de álcool, imagem corporal, sintomas depressivos e qualidade de vida (SF-36). A avaliação laboratorial incluiu glicose, insulina, hormônio tiroestimulante, perfil lipídico e função renal. Os grupos foram comparados pelos testes Qui Quadrado e t de Student. Resultados:a média de idade das participantes foi 41±10,9 anos e a totalidade da amostra apresentava obesidade abdominal, com média da circunferência da cintura de 110±11,0 cm, 70% eram hipertensas, com média de pressão arterial sistólica de 133±13,0 mmHg e pressão arterial diastólica de 89±11,0 mmHg. Além disso, 95% eram sedentárias, 7% eram fumantes, 12% faziam uso nocivo do álcool, 98% declararam insatisfação com a imagem corporal e 62% apresentavam depressão. Observou-se presença de compulsão alimentar periódica em 57% das mulheres avaliadas. Os pacientes com compulsão alimentar periódica eram mais jovens (20 a 39 anos) (53,5% vs. 30,2%; p=0,010) e tinham pior qualidade de vida (93,6± 19,6 vs. 104,3± 19,8; p=0,039). Quanto aos parâmetros laboratoriais, não foi observada diferença significativa entre os grupos. Conclusão: a presença de compulsão alimentar periódica foi achado frequente em mulheres mais jovens com síndrome metabólica, associada com pior qualidade de vida. Estes achados alertam para a importância do rastreio da compulsão alimentar periódica em indivíduos com síndrome metabólica para contribuir para manejo clínico mais adequado desta população.

Introduction: obesit y, one of the main components of metabolic syndrome, is frequently associated with binge eating. Objective: the aim of this study was to evaluate the occurrence of binge eating in women with metabolic syndrome and its possible association with sociodemographic, clinical, and behavioral parameters. Material and methods: a cross-sectional study with 124 individuals with metabolic syndrome, divided according to the presence or absence of binge eating, based on the criteria of the Binge Eating Scale (BES). We quantified weight, height, waist circumference, and office blood pressure. We evaluated behavioral parameters: level of physical activity, alcohol consumption, body image, depressive symptoms, and quality of life (SF-36). Laboratory evaluation included glucose, insulin, thyroid stimulating hormone, lipid profile, and renal function. The groups were compared by Chi-square and student t tests. Results: the mean age of the participants was 41±10.9 years and the entire cohort presented abdominal obesity, with an average waist circumference of 110±11.0 cm, while 70% of the individuals were hypertensive, with an overall mean systolic and diastolic blood pressure of 133±13.0 mmHg and 89±11.0 mmHg, respectively. In addition, 95% were sedentary, 7% were smokers, 12% abused alcohol, 98% declared dissatisfaction with body image, and 62% had depression. We observed the occurrence of binge eating in 57% of the women evaluated. The patients with binge eating were younger (20 to 39 years) (53,5% vs. 30,2%; p=0.010) and had worse quality of life (93,6± 19,6 vs. 104,3± 19,8; p=0.039). Regarding laboratory parameters, there were no significant differences between the groups. Conclusion: the occurrence of binge eating was a frequent finding in younger women with metabolic syndrome associated with worse quality of life. These findings alert to the importance of binge eating tracking in individuals with metabolic syndrome to contribute for a more appropriated clinical management of this population.

[Spironolactone reduces blood pressure and albuminuria of obese hypertensive patients with metabolic syndrome]. / Espironolactona reduz a pressão arterial e a albuminúria de hipertensos obesos com síndrome metabólica.

INTRODUCTION: In recent years, a role for aldosterone in pathophysiology of metabolic syndrome and hypertension in this syndrome has been suggested. However, the treatment with antagonists of mineralocorticoid receptor in these individuals has not properly addressed. OBJECTIVE: To evaluate the effects of mineralocorticoid receptor blockade on blood pressure, inflammatory, metabolic and renal parameters in non-diabetic hypertensive individuals with the metabolic syndrome. METHODS: Twenty nine patients with metabolic syndrome were enrolled in a prospective protocol that consisted of 2 periods: baseline (2 weeks) in which demographic data were obtained and antihypertensive medicines were withdrawn, and treatment period when the individuals were treated with spironolactone 25-50 mg once-a-day, for 16 weeks. In both periods, inflammatory, metabolic and renal parameters were assessed and the 24-hour ambulatory blood pressure monitorization was performed. RESULTS: After spironolactone treatment, 24 hour systolic and diastolic blood pressure decreased from 143.5 ± 15.17 mmHg to 133.2 ± 17.34 mmHg (p = 0.025) and from 85.2 ± 11.10 mmHg to 79.3 ± 11.78 mmHg (p = 0.026), respectively. HDL-cholesterol increased from 44.0 ± 8.67 mg/dl to 49.0 ± 6.75mg/dl (p = 0.000) and C-reactive protein decreased significantly from 6.3 ± 7.54 mg/l to 4.6 ± 6.3 mg/l (p = 0.009). Fasting plasma glucose, insulin, HOMA-IR and triglycerides did not change significantly after mineralocorticoid receptor blockade. Estimated glomerular filtration rate did not change whereas the logarithm of albuminuria decreased significantly from 2.5 ± 0.92 to 2.0 ± 0.9 (p = 0.028). CONCLUSION: In hypertensive subjects with MS the administration of spironolactone in monotherapy was effective for hypertension control, decreased urinary albumin excretion and increased HDL-cholester ol plasma.

Weight loss improves renal hemodynamics in patients with metabolic syndrome.

OBJECTIVE: We investigated the impact of weight loss on urinary albumin excretion (UAE) and creatinine clearance in obese patients with metabolic syndrome. METHODS: Thirty-five obese patients undertook a 12-week calorie-restricted diet. The patients underwent a metabolic (oral glucose tolerance test, plasma lipids, and uric acid) and renal hemodynamic evaluations (creatinine clearance and urinary albumin excretion) before (phase 1), and after the 12-week diet (phase 2). RESULTS: After the dietary intervention, the subjects were divided into two groups: patients who achieved the target weight reduction (R: responders, n = 14), and patients who did not (NR: non-responders, n = 21). The patients in Group R showed an improvement in lipid profile, a decrease in UAE (median = 162.5 mg/24 hours, range: 0.8 to 292 mg/24 hours, at phase 1 versus 10.4 mg/24 hours, range: 1.6 to 22.4 mg/24 hours, at phase 2), and a significant reduction in creatinine clearance (121.4 ± 66.5 mL/min. in phase 1 to 92.9 ± 35.6 mL/min. at the end of phase 2, p = 0.001). In Group NR, no statistically significant differences were observed between phases 1 and 2. CONCLUSION: Body weight reduction has a positive impact on renal hemodynamics, decreasing urinary albumin excretion as well as glomerular hyperfiltration in obese patients with metabolic syndrome.

Efeito da perda de peso sobre a hemodinâmica renal em portadores da síndrome metabólica / Weight loss improves renal hemodynamics in patients with metabolic syndrome

OBJETIVO: No presente artigo, investigou-se o impacto da redução do peso corporal na excreção urinária de albumina e na depuração da creatinina em indivíduos obesos com síndrome metabólica. MÉTODOS: Trinta e cinco indivíduos foram submetidos à dieta hipocalórica por um período de 12 semanas, visando uma redução mínima de 5% do peso corporal. Os voluntários foram submetidos à avaliação metabólica (teste oral de tolerância à glicose, dosagens de lípides plasmáticos e ácido úrico) e à avaliação de parâmetros hemodinâmicos renais (depuração da creatinina e excreção urinária de albumina), antes (fase 1) e após 12 semanas de dieta hipocalórica (fase 2). RESULTADOS: Após o período de intervenção, os voluntários foram divididos em dois grupos: indivíduos que atingiram o alvo para redução de peso (respondedores: R, n = 14) e pacientes que não atingiram a meta para redução de peso (não-respondedores: NR, n = 21). Indivíduos do Grupo R apresentaram melhora do perfil lipídico, da redução da excreção urinária de albumina (mediana = 162.5 mg/24 horas, variação: 0,8 a 292 mg/24 horas, na fase 1 para 10,4 mg/24 horas, variação: 1,6 a 22,4 mg/24 horas, na fase 2), além de redução significante da depuração da creatinina (121,4 ± 66,5 mL/min. para 92,9 ± 35,6 mL/min., p = 0,001). No Grupo NR, não foram observadas diferenças estatisticamente significantes entre as fases 1 e 2 do estudo. CONCLUSÃO: A redução do peso corporal teve impacto positivo na hemodinâmica renal, reduzindo a excreção urinária de albumina e a hiperfiltração glomerular em indivíduos obesos com síndrome metabólica.

Risco cardiovascular na síndrome metabólica: estimativa por diferentes escores / Cardiovascular risk in metabolic syndrome: estimating by different criteria

JUSTIFICATIVA E OBJETIVOS: A síndrome metabólica (SM) constitui importante indicador de risco cardiovascular, estando associada a elevadas taxas de mortalidade por doença arterial coronariana (DAC). O objetivo deste estudo foi comparar três diferentes escores de avaliação de DAC em portadores de SM. MÉTODO: Trinta e nove pacientes não diabéticos, portadores de SM foram avaliados pelo Escore de Risco de Framingham (ERF), pelo ERF modificado pela IV Diretriz Brasileira sobre Dislipidemias e Aterosclerose (ERF-mod) e pelo escore do Prospective Cardiovascular Münster Study (PROCAM). RESULTADOS: O risco estimado de DAC pelo ERF foi baixo em 35 (90%) indivíduos e médio, em quatro (10%), não sendo detectado alto risco em nenhum caso. Pelo PROCAM, 29 (74%) indivíduos continuaram na faixa de baixo risco, sete (18%) apresentaram médio risco e três (8%); alto risco. Por outro lado, o ERF-mod detectou cinco casos (13%) de baixo risco, 30 (77%) casos de médio risco e quatro (10%) de alto risco. CONCLUSÃO: Comparado com o ERF-mod, o ERF subestimou o cálculo do risco de DAC em pacientes com SM, enquanto o PROCAM apresentou eficácia ligeiramente superior ao ERF.

BACKGROUND AND OBJECTIVES: Metabolic syndrome (MS) is an indicator of cardiovascular risk associated with high rates of coronary heart disease (CHD) mortality. The aim of this study was to assess the CHD risk in patients with metabolic syndrome (MS) using three different scores. METHOD: Thirty nine non-diabetic patients with MS were evaluated by the Framingham Risk Score (FRS), FRS modified by IV Diretriz Brasileira sobre Dislipidemias e Aterosclerose (mod-FRS) and by Prospective Cardiovascular Münster Study score (PROCAM). RESULTS: Based in the FRS the CHD risk in 10 years was considered low in 35 (90%) individuals and intermediate in 4 (10%), with no patient in high risk group. According to PROCAM 29 (74%) individuals were in low risk group, 7 (18%) in the intermediate risk and 3 (8%) in high risk group. On the other hand, the mod-FRS detected 5 (13%) subjects in low risk, 30 (77%) in the intermediate and 4 (10%) individuals in the high risk group.CONCLUSION: Framingham Risk Score was less accurate than the FRS-mod for the assessment of CHD risk in subjects with MS while the PROCAM score was slightly better than FRS for this purpose.

Diabetes mellitus tipo 1 de curta duração e suas implicações sobre a qualidade de vida / Type 1 diabetes mellitus short term and its implications on the quality of life

Objetivo: O diabetes mellitus tipo 1 representa condição crônica de saúde frequente na população pediátrica e possui impacto significativo sobre qualidade de vida destes indivíduos. O objetivo do presente estudo é avaliar a qualidade de vida em indivíduos com diabetes mellitus tipo 1 de curta duração, sob a ótica dos pacientes e dos seus cuidadores. Métodos: Aplicação dos questionários PedsQL 4.0 e Instrumento de Qualidade de Vida para Jovens com Diabetes. Resultados: Dentre os 15 pacientes (e seus cuidadores) avaliados, observou-se que a maior parte dos indivíduos entrevistados considerou sua saúde como boa, em relação à das demais pessoas e a autopercepção da qualidade de vida não se mostrou, de forma geral, prejudicada pelo diabetes. Conclusão: Tendo em vista que a ausência de complicações crônicas e a percepção de boa saúde estão intimamente relacionadas, destaca-se a importância da intervenção precoce, por parte da equipe de saúde, com objetivo de promover atividades de educação em saúde, voltadas às necessidades desse grupo de indivíduos.
