Abstract Introduction: obesity is a public health problem. No significant decrease in the prevalence of obesity has been globally observed. A better understanding of the factors that can influence obesity is necessary, one of them being self-perception of body weight. Objective: to determine the agreement between self-perception of body image and Nutritional status in a Chilean population. Methods: an analytical cross-sectional study was carried out based on the Chilean National Health Survey 2016-2017. Nutritional status was measured by body mass index (BMI) and self-perceived body weight. Agreement was estimated by the kappa index and weighted kappa index. These indices were specified according to sociodemographic variable. Results: the total number of participants was 5483, with 51 % (95 % CI: 48.7-53.5) corresponding to women. Mean age was 43.2 years (95 % CI: 42.4-44.0). The kappa index showed a low concordance (kappa, 0.194; 95 % CI: 0.177 to 0.211) among women, people from rural areas, and subjects with fewer years of education. The global weighted kappa was 0.325; 95 % CI (0.168-0.482). Conclusions: underestimation of Nutritional status can lead to negation of the problem generated by excess body weight. Recognizing Nutritional status is a critical stage to initiate behavior changes and start having healthy eating habits. More than half of Chileans present distortion of body image, prevailing underestimation of body weight.

Resumen Introducción: la obesidad es un problema de salud pública. No se ha observado una disminución significativa de la prevalencia de la obesidad a nivel mundial. Es necesaria una mejor comprensión de los factores que pueden influir en la obesidad y uno de ellos es la autopercepción del peso corporal. Objetivo: determinar la concordancia entre la autopercepción de la imagen corporal y el estado nutricional real en la población chilena de 15 y más años. Métodos: se realizó un estudio transversal analítico basado en la Encuesta Nacional de Salud de Chile 2016-2017. Se midió el estado nutricional junto con la autopercepción del peso corporal. Se estimó el índice de concordancia kappa y el kappa ponderado. Estos índices se especificaron según la variable sociodemográfica. Resultados: un 51 % (IC 95 %: 48,7-53,5) corresponden a mujeres. La edad media fue de 43,2 años (IC 95 %: 42,4-44,0). El índice kappa mostró una baja concordancia (kappa: 0,194; IC 95 %: 0,177 a 0,211), siendo inferior en las mujeres, las personas de área rural y las de menos años de educación. El kappa ponderado global fue de 0,325; IC 95 % (0,168-0,482). Conclusiones la subestimación del estado nutricional favorece la negación del problema que genera el exceso de peso corporal. Reconocer el estado nutricional que se tiene es una etapa crítica para iniciar un cambio de comportamiento; por lo tanto, evaluar incorrectamente el peso corporal impide iniciar hábitos de alimentación saludable. Más de la mitad de los chilenos presentan distorsión de la imagen corporal, prevaleciendo la subestimación del peso corporal.

Abstract Introduction: during hematopoietic stem cell transplantation (HSCT) some factors may impact on the patient's nutritional status (NS). Conditioning regimen, as well as signs and symptoms of the gastrointestinal tract, can negatively influence on oral food intake. Patients may require the use of complementary nutritional therapies aiming at an adequate caloric intake with the objective of avoiding decreasing in NS. Objective: the study aims to describe the nutritional aspects relevant to the maintenance of NS during hospitalization of children and adolescents undergoing HSCT at a tertiary hospital. Method: a retrospective study with a review of medical records of patients undergoing HSCT, aged between 0 and 19 years of age (incomplete) between January 2009 and December 2014. Data were collected regarding food intake, nutritional therapies used, and clinical signs and symptoms in six times: hospitalization, D0 (day of cell infusion), D+7, D+14, D+21 and D+28. Results: sixty-three patients were evaluated, being 56% males, with a median age of ten years. At the time of hospitalization, 100% of patients had their energy needs met by mouth, decreasing from D0 (about 30%), with more prevalent use of parental nutritional and enteral nutrition from D+7. Loss of appetite, mucositis and nausea were the most frequent signs and symptoms. From D+21 it was possible to observe an increase in caloric intake by mouth. Conclusion: patients showed decreased food intake throughout hospitalization. However, it has been shown that the prescription of complementary nutritional therapies has reduced the impact of weight loss.

Resumen Introducción: durante el trasplante de células madre hematopoyéticas (TCMH) algunos factores pueden influir en el estado nutricional (EN) del paciente. El régimen de acondicionamiento, así como los signos y síntomas del tracto gastrointestinal, pueden influir negativamente en la ingesta oral de alimentos. Los pacientes pueden requerir el uso de terapias nutricionales complementarias dirigidas a una ingesta calórica adecuada con el objetivo de evitar el deterioro del EN. Objetivo: el estudio tiene como objetivo describir los aspectos nutricionales relevantes para el mantenimiento del EN durante la hospitalización de niños y adolescentes sometidos al TCMH en un hospital terciario. Método: un estudio retrospectivo con una revisión de los registros médicos de los pacientes sometidos al TCMH, con edades comprendidas entre 0 y 19 años (incompletos) entre enero de 2009 y diciembre de 2014. Se recopilaron datos sobre la ingesta de alimentos, las terapias nutricionales utilizadas y los signos y síntomas clínicos en seis tiempos: hospitalización, D0 (día de infusión celular), D+7, D+14, D+21 y D+28. Resultados: se evaluaron sesenta y tres pacientes, siendo 56% del sexo masculino, con una edad media de diez años. En el momento de la hospitalización 100% de los pacientes cubrían sus necesidades energéticas con la alimentación oral, disminuyendo en el D0 (alrededor del 30%), con un uso más prevalente de nutrición enteral y parenteral en el D+7. La inapetencia, mucositis y náuseas fueron los signos y síntomas más frecuentes. Desde el D+21 fue posible observar un aumento en la ingesta calórica por vía oral. Conclusión: los pacientes mostraron una disminución en la ingesta de alimentos durante la hospitalización. Sin embargo, se ha demostrado que la prescripción de terapias nutricionales complementarias ha reducido el impacto de la pérdida de peso.

BACKGROUND: The development of nutrition care programs for patients undergoing hematopoietic stem cell transplantation is necessity in view of the rapid and aggressive consequences frequently seen with this procedure. Patients require constant care to reduce complications and to contribute to the success of therapy. METHODS: In an attempt to ascertain the impact of systematic nutritional care on patients submitted to allogeneic hematopoietic stem cell transplantation, the present study assessed the nutritional and clinical status, use of parenteral nutrition, and complication and mortality rates in two groups of patients, who were submitted to transplantation between April 2003 and December 2004 (Non-intervention Group - NIG; n = 57) and between March 2006 and January 2008 (Intervention Group - IG; n = 34). RESULTS: There were no significant differences between groups in terms of clinical or nutritional profiles. Additionally, the length of hospital stay and complication and mortality rates were similar for both groups. However, time on parenteral nutrition during treatment was shorter for the IG [median 6.5 days (range: 1-28) for related donor recipients and 11 days (range: 1-21) for unrelated donor recipients] than for the NIG [median 20.5 days (range, 4-73) for patients submitted to myeloablative conditioning and 18.5 days (range: 11-59 days) for those submitted to nonablative conditioning]. CONCLUSION: The implementation of a nutritional follow-up and therapy protocol for adult patients submitted to hematopoietic stem cell transplantation shortens the duration of parenteral nutrition. It certainly has an impact on hospitalization costs and, potentially, on the rate of complications, even though this was not demonstrated in this study.

Um indivíduo de Glironia venusta (Didelphimorphia), foi observado na Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brasil. Existem apenas 17 outros registros publicados desta espécie de marsupial, a maioria da década de 80. No Brasil, G. venusta havia sido registrada em três outras localidades, no Pará, Amazonas e Rondônia. Com este registro em uma das áreas mais intensivamente estudadas na Amazônia, ganha reforço a noção de que G. venusta é uma espécie rara localmente, mas de ampla distribuição na Amazônia brasileira.

A new record of a very rarely observed mammal, the bushy-tailed opossum, Glironia venusta (Didelphimorphia), was obtained for the Adolpho Ducke Forest Reserve, Manaus, Amazonas state, Brazil. Only 17 other records existed of this species, most from the 1980s. There were only three previous records of the species from Brazil (in the states of Pará, Amazonas and Rondônia). This new record supports the notion that G. venusta is a locally rare species throughout its range, but widely distributed in Brazilian Amazonia.
