RESUMEN
Introducción: La desnutrición es frecuente en el paciente oncológico y se asocia a una menor respuesta a la radioterapia, quimioterapia y un mayor índice de mortalidad. Es sumamente importante identificar aquellos pacientes malnutridos y en riesgo de desnutrición para realizar una intervención nutricional de manera precoz e individualizada. Objetivo: Valorar el estado nutricional y describir la prevalencia de malnutrición en pacientes adultos en tratamiento oncológico, que concurren al Hospital de Día de Oncología del HIGA "Profesor Dr. Luis Güemes", Haedo. Materiales y métodos: Este estudio descriptivo transversal, desarrollado entre los meses de julio del 2021 y mayo de 2022, se realizó en pacientes adultos que asisten al Hospital de Día de Oncología en forma ambulatoria. Para el cribado nutricional se utilizó la herramienta NutriScore y los criterios GLIM para el diagnóstico de desnutrición. Resultados: El tamaño muestral fue de 93 personas. La localización más frecuente fue el cáncer de mama (29%), seguido por pulmón (4%), útero (13%) y, por último, colon (11%). El 23% de los pacientes se encontraban en riesgo nutricional. Al aplicar los criterios GLIM se evidenció una prevalencia de desnutrición del 23%, siendo el 48% moderada y el 52% severa. Por otro lado, solo el 6,5% presentaban bajo peso y el 52,6% presentaba exceso de peso. Conclusiones: La malnutrición es un diagnóstico frecuente en pacientes oncológicos, teniendo importantes repercusiones a nivel de la morbimortalidad, la calidad de vida y los costos sanitarios. Se recomienda realizar detección de riesgo y valoración del estado nutricional en todos los pacientes con diagnóstico oncológico con el objetivo de instaurar un abordaje nutricional precoz y adecuado
Introduction: Malnutrition is common in cancer patients and is associated with a lower response to radiotherapy, chemotherapy and a higher mortality rate. It is extremely important to identify those malnourished patients and at risk of malnutrition to perform a nutritional intervention early and individualized. Objective: To assess the nutritional status and describe the prevalence of malnutrition in adult patients undergoing cancer treatment, who attend the Oncology Day Hospital of the HIGA ''Profesor Dr. Luis Güemes'', Haedo. Materials and methods: This cross-sectional descriptive study developed between the months of July 2021 and May 2022 was carried out in adult patients who attend the Oncology Day Hospital as an outpatient. The NutriScore tool and the GLIM criteria were used for the nutritional assessment. Results: The sample size was 93 people. The most frequent location was breast cancer (29%), followed by lung (4%), uterus (13%) and finally colon (11%). 23% of patients were at nutritional risk. When applying the GLIM criteria, a prevalence of malnutrition of 23% was evident, being 48% moderate and 52% severe. On the other hand, only 6.5% were underweight and 52.6% were overweight. Conclusions: Malnutrition is a frequent diagnosis in cancer patients, having important repercussions in terms of morbidity and mortality, quality of life and health costs. It is recommended to perform risk detection and assessment of nutritional status in all patients with an oncological diagnosis with the aim of establishing an early and appropriate nutritional approach

OBJECTIVE: A single-nucleotide polymorphism (SNP), the G variant in codon 1013 (GAA1013-->GAG) of the insulin-like growth factor-1 (IGF-1) receptor (IGFIR) gene, has been associated with higher IGF-1 concentrations in Caucasian subjects. Because elevated serum levels of IGF-1 have been described in children with premature pubarche (PP) and in adolescent girls with hyperandrogenism, we tested the a priori hypothesis that the frequency of the A-->G variant would be overrepresented among children with PP. DESIGN: Case-control association study. SETTING: University-based pediatric endocrinology practice. PATIENT(S): Sixty-nine children (63 girls and 6 boys) with PP, 52 adolescent girls with hyperandrogenism, and 92 healthy subjects. INTERVENTION(S): Blood was obtained for genotype analysis, glucose measurement, and hormone (A, insulin, 17-hydroxyprogesterone, and T) determinations. MAIN OUTCOME MEASURE(S): Frequency of the SNP in the IGF1R gene and correlation of this SNP with hormone concentrations. RESULT(S): Distribution of the G allele was statistically significantly different between the children with PP and the healthy control subjects, independent of insulin sensitivity. CONCLUSION(S): This common SNP in the IGF1R gene may be associated with PP caused by premature adrenarche in children. Because PP has been associated with higher IGF-1 concentrations, these data suggest a potential molecular basis for prior clinical observations of elevated IGF-1 concentrations in children with PP.
