ABSTRACT
In recent years, high-energy ultrasound has been used as an alternative to improve the functional properties of various proteins, such as from milk, eggs, soy and poultry. The benefits of implementing this technology depend on the inherent characteristics of the protein source and the intensity and amplitude of the ultrasound, as well as on the pH, temperature, ionic strength, time, and all of the variables that have an effect on the physicochemical properties of proteins. Therefore, it is necessary to establish the optimal conditions for each type of food. The use of ultrasound is a promising technique in food technology with a low impact on the environment, and it has thus become known as a green technology. Therefore, this review focuses on the application of high-energy ultrasound to food; its effects on the functional properties of proteins; and how different conditions such as the frequency, time, amplitude, temperature, and protein concentration affect the functional properties.

El objeto del presente estudio fue analizar las dietas de 39 mujeres (edad media = 34.3 años; IMC medio = 26.2 kg/m²) sanas y con lactancia exclusiva, mediante Encuesta Dietética de Recordatorio de 24 horas y utilizando el software Dial®, centrándonos en el aporte diario de calcio y vitamina D. La población a estudio se agrupó en función de si su ingesta en calcio era mayor (no restrictivas) o menor (restrictivas) a la Ingesta de Referencia para la Población según la Unión Europea. Los resultados obtenidos revelaron inicialmente que en un 64 por ciento de dicha población (restrictivas) el aporte energético seguía una tendencia deficitaria, siendo de 2042.7 ± 458.3 kcal. Además su ingesta de calcio (812.4 ± 211.2 mg/día) fue inferior (p<0.01) a la recomendada, así como la ingesta en vitamina D, en donde su aporte diario también fue deficitario (1.71 ± 1.59 µg/día) respecto al resto de la población (no restrictivas). Tras estos resultados, se puede concluir que un alto porcentaje de estas madres se encuentra por debajo de las recomendaciones nutricionales durante su etapa de lactancia, siendo aconsejable que fueran informadas por los profesionales sanitarios sobre los hábitos alimentarios requeridos en este periodo.
The aim of this study was to analyze the diets of 39 healthy, lactating women (average age = 34.3 years; average BMI = 26.2 kg/m²) by a 24-hour dietary recall. This investigation was focused on calcium and vitamin D intake. Nutrients were estimated using the software Dial®. These participants were divided into calcium restrictors, defined as calcium intake <1200 mg/day, and non-restrictors (>1200 mg/day). The results showed that 64 percent of the study population (restrictors) reported a mean energy intake (2042.7 ± 458.3 kcal), calcium intake (812.4 ± 211.2 mg/day) and vitamin D intake (1.71 ± 1.59 µg/day) below the adequate intake level (AI) and lower than non-restrictors estimated intakes (p<0.01). The conclusion of this study is that a high percentage of the lactating women consume a diet below nutritional recommendations during this stage. It is recommended that health professionals should inform these mothers about the correct dietary habits during this period.

We report the clinical case of a man who survived a massive attack of Africanized bees (>2000 bee stings). The man experienced anaphylactic shock and multisystem organ failure (neurologic, hepatic, renal, and hematologic failure). He was treated with administration of dopamine hydrochloride, antihistaminic agents, corticosteroids, fluid and electrolyte replenishment, peritoneal dialysis, and plasmapheresis. No sequelae have been observed during follow-up.

Gastric carcinoid tumors arise from enterochromaffin-like (ECL) cells, these tumors represent 2-41% of all neuroendocrine tumors and 0.3% of malignant gastric neoplasias, being more common in men than in women, and commonly affecting people over 60 years old. These tumors arise from accelerated proliferation of the ECL cells as a consequence of the hypersecretion of gastrin, situation that can be present in atrophic gastritis and the Zollinger-Ellison syndrome. We report the case of a 51 year old hispanic female who presented with a 3 month history of abdominal pain, meteorism and constipation; she was treated with ranitidine and metoclopramide without clinical improvement, thus she underwent upper gastrointestinal endoscopy which showed an atrophic gastritis and gastric polyps. Histopathologic examination revealed a neuroendocrine gastric tumor which was positive to serotonine and gastrin stainings. Hormonal screening showed normal serum levels of LH, FSH, estradiol, ACTH, progesterone, calcitonin and cortisol. The serum level of gastrin was elevated with 500 pg/mL. Gammagraphic scanning with octreotide was negative for metastasis.
