ABSTRACT
ABSTRACT Objective: To evaluate anthropometric and clinical data, muscle mass, subcutaneous fat, spine bone mineral density, extent of acute pulmonary disease related to COVID-19, quantification of pulmonary emphysema, coronary calcium, and hepatic steatosis using chest computed tomography of hospitalized patients with confirmed diagnosis of COVID-19 pneumonia and verify its association with disease severity. Methods: A total of 123 adults hospitalized due to COVID-19 pneumonia were enrolled in the present study, which evaluated the anthropometric, clinical and chest computed tomography data (pectoral and paravertebral muscle area and density, subcutaneous fat, thoracic vertebral bodies density, degree of pulmonary involvement by disease, coronary calcium quantification, liver attenuation measurement) and their association with poorer prognosis characterized through a combined outcome of intubation and mechanical ventilation, need of intensive care unit, and death. Results: Age (p=0.013), body mass index (p=0.009), lymphopenia (p=0.034), and degree of pulmonary involvement of COVID-19 pneumonia (p<0.001) were associated with poor prognosis. Extent of pulmonary involvement by COVID-19 pneumonia had an odds ratio of 1,329 for a poor prognosis and a cutoff value of 6.5 for increased risk, with a sensitivity of 64.9% and specificity of 67.1%. Conclusion: The present study found an association of high body mass index, older age, extent of pulmonary involvement by COVID-19, and lymphopenia with severity of COVID-19 pneumonia in hospitalized patients.
ABSTRACT
ABSTRACT The Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Children and Adolescents was developed by dietitians, physicians, and pediatric hematologists from 10 Brazilian reference centers in hematopoietic stem cell transplantation. The aim was to emphasize the importance of nutritional status and body composition during treatment, as well as the main characteristics related to patient´s nutritional assessment. This consensus is intended to improve and standardize nutrition therapy during hematopoietic stem cell transplantation. The consensus was approved by the Brazilian Society of Bone Marrow Transplantation.

ABSTRACT BACKGROUND: Weight loss and body composition changes are common in patients with pancreatic cancer. Computed tomography (CT) images are helpful to investigate body composition and its changes and to discriminate the different kinds of body tissues. Patients with pancreatic cancer routinely undergo CT scans. OBJECTIVE: To verify the association of muscle mass and visceral fat measured by CT with toxicity and survival of patients with pancreatic cancer. METHODS: We evaluated the imaging of the abdomen of all consecutive adult patients with pancreatic cancer treated between October 2007 and September 2015 in our service, to assess skeletal muscle mass and fat, intramuscular fat and visceral fat. We graded treatment toxicity symptoms according to the Common Toxicity Criteria of the United States National Cancer Institute (version 2.0). RESULTS: The study involved 17 patients, with a mean age of 63 (±10) years (range: 51-73 years). Eleven (65%) were male. The mean initial body mass index (BMI) was 26 kg/m2 (±3) and 23 kg/m2 (±3) after treatment. The mean weight loss was 10.0 kg (±6.8; 13%). Sarcopenia was present in 47% of patients, and it was not associated with significant differences in muscle mass, visceral fat, toxicity or survival. The mean skeletal muscle attenuation was 36 Hounsfield units, not associated with survival or treatment toxicity. Mean muscle mass was not associated with toxicity either. However, there was a significant inverse association between toxicity and visceral fat. CONCLUSION: Muscle mass had no impact on the survival or on treatment toxicity among the patients with pancreatic cancer. However, the visceral fat exerted a protective effect against the treatment toxicity. We stress the importance of further studies on visceral fat associated with prognosis and toxicity in cancer patients.
RESUMO CONTEXTO: Perda de peso e mudanças na composição corpórea são frequentes em pacientes com câncer do pâncreas. Imagens de tomografia computadorizada são úteis na investigação da composição corporal e suas mudanças e para discriminar diferentes tipos de tecidos corporais. Pacientes com câncer pancreático são submetidos à tomografia computadorizada rotineiramente. OBJETIVO: Verificar a associação entre massa muscular e gordura visceral medida por tomografia computadorizada e a toxicidade do tratamento e a sobrevida de pacientes com câncer de pâncreas. MÉTODOS: Avaliamos imagens tomográficas abdominais de todos os pacientes adultos com câncer pancreático consecutivamente tratados entre outubro de 2007 e setembro de 2015 no serviço, para estimativa da massa muscular esquelética e gordura, tecido adiposo intramuscular e visceral. Classificamos a toxicidade do tratamento conforme os Critérios Comuns de Toxicidade do Instituto Nacional do Câncer dos Estados Unidos (versão 2.0). RESULTADOS: O estudo envolveu 17 pacientes, com idade média de 63 (±10) anos (51-73 anos); 11 (65%) homens. O índice de massa corporal médio inicial foi de 26 kg/m2 (±3); 23 kg/m2 (±3) após o tratamento. A perda de peso média foi de 10,0 kg (±6,8; 13%). Observamos sarcopenia em 47% dos pacientes, não associada a diferenças significativas na massa muscular, tecido adiposo visceral, toxicidade ou sobrevivência. A atenuação média do músculo esquelético foi de 36 unidades Hounsfield, não associada à sobrevivência ou toxicidade. A massa muscular média também não foi associada à toxicidade. No entanto, observamos associação inversa significativa entre toxicidade e gordura visceral. CONCLUSÃO: A massa muscular não teve impacto na sobrevida ou na toxicidade do tratamento dos pacientes com câncer pancreático. No entanto, a gordura visceral exerceu efeito protetor contra a toxicidade. Ressaltamos a importância de mais estudos sobre a gordura visceral associada ao prognóstico e à toxicidade em pacientes com câncer.

ABSTRACT The nutritional status of patients submitted to hematopoietic stem cell transplant is considered an independent risk factor, which may influence on quality of life and tolerance to the proposed treatment. The impairment of nutritional status during hematopoietic stem cell transplant occurs mainly due to the adverse effects resulting from conditioning to which the patient is subjected. Therefore, adequate nutritional evaluation and follow-up during hematopoietic stem cell transplant are essential. To emphasize the importance of nutritional status and body composition during treatment, as well as the main characteristics related to the nutritional assessment of the patient, the Brazilian Consensus on Nutrition in Hematopoietic Stem Cell Transplant: Adults was prepared, aiming to standardize and update Nutritional Therapy in this area. Dietitians, nutrition physicians and hematologists from 15 Brazilian centers thar are references in hematopoietic stem cell transplant took part.
RESUMO O estado nutricional do paciente submetido ao transplante de células-tronco hematopoéticas é considerado fator de risco independente, podendo influenciar na qualidade de vida e na tolerância ao tratamento proposto. O comprometimento do estado nutricional durante o transplante de células-tronco hematopoéticas ocorre principalmente devido aos efeitos adversos decorrentes do condicionamento ao qual o paciente é submetido. Desta forma, a adequada avaliação nutricional e o acompanhamento durante o transplante de células-tronco hematopoéticas tornam-se imprescindíveis. Com o objetivo de salientar a importância do estado nutricional e da composição corporal durante o tratamento, bem como as principais características relacionadas à avaliação nutricional do paciente, o Consenso Brasileiro de Nutrição em Transplante de Células-Tronco Hematopoiéticas: Adulto foi elaborado visando uniformizar e atualizar a Terapia Nutricional nesta área. Com a participação de nutricionistas, nutrólogos e hematologistas de 15 centros brasileiros referências em transplante de células-tronco hematopoéticas

SUMMARY OBJECTIVE: This study aims to evaluate the sleep of subjects with polycystic ovary syndrome (PCOS), with and without hyperandrogenism, in comparison with a healthy control group and examine the effects of hyperandrogenism and obesity on sleep parameters. METHODS: A total of 44 volunteers were recruited to participate in the study. Clinical, biochemical and polysomnographic parameters were used to diagnose PCOS and hyperandrogenism. The evaluation of sleep quality was made using validated questionnaires and polysomnography test. The frequency of obstructive sleep apnea was also compared between the groups. RESULTS: The study revealed that women with PCOS presented poorer subjective sleep quality, increased incidence of snoring and a higher risk of obstructive sleep apnea, based on the Berlin questionnaire. Also, after adjusting for body mass index, PCOS subjects had rapid eye movement (REM) time lower than those in the control group. PCOS women versus those without hyperandrogenism did not differ on any sleep measurement. Women with obstructive sleep apnea were only diagnosed in the PCOS group. CONCLUSIONS: Our results indicate that PCOS impairs subjective sleep quality, as well as objective sleep quality, due to a reduction in REM sleep stage time in women diagnosed with the syndrome. Obesity affected sleep-related parameters but hyperandrogenism had no effect. Only the PCOS group had obstructive sleep apnea diagnosis.
RESUMO OBJETIVO: Este estudo objetivou avaliar o sono de mulheres com síndrome do ovário policístico, com e sem hiperandrogenismo, em comparação com um grupo controle saudável, e estudar os efeitos do hiperandrogenismo e da obesidade nos parâmetros do sono. MÉTODOS: Um total de 44 voluntárias foram recrutadas para participar do estudo. Os parâmetros clínicos, bioquímicos e polissonográficos e foram usados para diagnosticar SOP e hiperandrogenismo. A avaliação da qualidade de sono foi feita usando questionários validados e o exame polissonográfico. A frequência de síndrome da apneia obstrutiva também foi comparada entre os grupos. RESULTADOS: O estudo revelou que mulheres com SOP apresentaram menor qualidade de sono subjetiva, incidência aumentada de ronco e maior risco para síndrome da apneia obstrutiva, baseada no questionário de Berlin. Ademais, após o ajuste para índice de massa corpórea, mulheres com SOP tiveram menor tempo de sono REM do que aquelas do grupo controle. Dentre as mulheres com SOP, aquelas com hiperandrogenismo não tiveram diferenças em nenhuma variável do sono. Mulheres com síndrome da apneia obstrutiva foram diagnosticadas no grupo SOP. CONCLUSÕES: Nossos resultados indicam que a SOP afeta a qualidade subjetiva de sono, bem como a qualidade objetiva e do sono, em razão da redução do tempo de sono REM em mulheres diagnosticadas com a síndrome. A obesidade afetou parâmetros relacionados ao sono, mas o hiperandrogenismo não teve efeito. A síndrome da apneia obstrutiva somente foi diagnosticada em mulheres com SOP.
