[Improving the nutritional care of oncology patients - Validation of a multidisciplinary protocol in the Spanish clinical setting]. / Mejorando la atención nutricional del paciente oncológico: validación de un protocolo multidisciplinar en el entorno clínico español.

INTRODUCTION: malnutrition is a very frequent problem in oncology patients and can have serious repercussions. Adequate nutritional management is cost-effective in terms of health and survival in this population, but it requires multidisciplinary coordination, specific training, and continuous follow-up. OBJECTIVE: to validate the applicability and efficacy of a multidisciplinary nutritional support protocol in oncology patients. METHODS: a multidisciplinary nutritional protocol was developed for oncology patients, with guidelines for screening and assessment of malnutrition, treatment, re-evaluation, and management of side effects, as well as guidance on supplementation and eating patterns. The protocol would be implemented in various clinical centers, collecting data through a structured questionnaire, registering variables before and after implementation. RESULTS: the protocol and its impact were implemented and evaluated in 39 centers. An improvement in nutritional care was observed, evidenced by an earlier initiation of nutritional assessment and an increase in the number of patients receiving adequate care following the protocol implementation. Problems related to inadequate malnutrition coding in the centers, limited resources, and the need for greater interdepartmental collaboration were identified. CONCLUSIONS: the conduct of this study provides insights into how the implementation of a multidisciplinary nutritional support protocol can improve the nutritional care received by patients and informs about the main obstacles to adequate implementation.

Secondary thyroid malignancy from metastatic colon lymphoma.

Primary thyroid malignancy is more frequent than secondary. This case report describes a colon lymphoma with unique thyroid metastasis. When a thyroid lesion appears in an extension study such as Positron emission tomography-computed tomography marked with 18F-2-fluoro-2-deoxy-D-glucose, it is recommended to perform an ultrasound. The correct study with ultrasound and cytology obtained through fine needle aspiration on thyroid lesion allowed to refine the diagnosis and provide the correct treatment.

Diagnosis of pre-sarcopenia from a single selectional crosscut at C3 region, using CT scans before radiotherapy.

INTRODUCTION: Purpose: the main purpose of this study was to diagnose pre-sarcopenia in cancer patients who had lack of computed tomography (CT) abdominal images, with a newly discovered method based on cervical images. Material and methods: a sample of 37 patients with either lung cancer or a cancer that affected the upper digestive system underwent radiotherapy computed simulation which included measurements at C3 and L3 regions. Skeletal muscle mass (SMM) and skeletal muscle index (SMI) were determined by Hounsfield units and compared in both regions. Pre-sarcopenia was identified according to the cut-points currently established: ≤ 41 cm2/m2 in females, ≤ 43 cm2/m2 in males with a BMI ≤ 25 kg/m2, and ≤ 53 cm2/m2 in males with a BMI > 25 kg/m2. Results: the correlation of SMM and SMI between the C3 and L3 regions was R2 = 0.876 and R2 = 0.805, respectively. Moreover, there was a positive association (86.49%) in terms of the diagnosis of pre-sarcopenia according to both regions. In total, eleven pre-sarcopenic patients (29.37%) were identified; three of them being overweight (27.27%) and two of them being obese (18.18%). Conclusion: a single sectional cross at the level of C3 can be used for the diagnosis of pre-sarcopenia. This new method avoids unnecessary irradiation, saves hospital costs and detects malnutrition before starting radiotherapy treatment in cancer patients who have lack of CT abdominal imaging.

INTRODUCCIÓN: Propósito: el propósito de este estudio fue diagnosticar la presarcopenia en pacientes con cáncer que no disponen de imágenes por tomografía computarizada (TC) a nivel abdominal mediante un método novedoso basado en cortes a nivel cervical. Material y métodos: se analizaron y se compararon mediante unidades la masa muscular y la masa muscular esquelética en 37 pacientes con cáncer de pulmón y neoplasias del aparato digestivo superior que incluían cortes en la TC de planificación a nivel de C3 y L3. La presarcopenia se identificó de acuerdo con los puntos de corte establecidos actualmente: ≤ 41 cm2/m2 para mujeres, ≤ 43 cm2/m2 en hombres con un IMC ≤ 25 kg/m2 y ≤ 53 cm2/m2 en hombres con IMC > 25 kg/m2. Resultados: la correlación de la masa muscular y el índice musculoesquelético entre las regiones C3 y L3 fue R2 = 0.876 y R2 = 0.805, respectivamente. Además, hubo una asociación positiva (86,49%) en términos del diagnóstico de presarcopenia según ambas regiones. En total, se identificaron once pacientes con presarcopenia (29,37%); tres de ellos con sobrepeso (27,27%) y dos con obesidad (18,18%). Conclusión: un solo corte transversal a nivel de la vértebra C3 puede diagnosticar la presarcopenia. Este nuevo método evita la irradiación innecesaria, ahorra costos hospitalarios y detecta la desnutrición antes de iniciar el tratamiento de radioterapia en pacientes con cáncer que no disponen de imágenes a nivel abdominal.

[Anorexia nervosa as a cause of acute liver failure. Report of a case]. / Anorexia nerviosa como causa de fallo hepático agudo. A propósito de un caso.

Caso clínico: presentamos una paciente de 33 años con anorexia nerviosa de 15 años de evolución con uno de los pocos casos reportados de fallo hepático agudo severo secundario a la desnutrición.Discusión: tras el soporte nutricional protocolizado para evitar el síndrome de realimentación y un adecuado manejo multidisciplinar, la paciente evoluciona favorablemente logrando normalizar los electrolitos, la función hepática y las alteraciones en la coagulación.
