RESUMEN
Adequate nutrition is critical to child development and institutions such as day-care centers could potentially complement childrens diets to achieve optimal daily intakes. The aim of the study was to describe the full-day diet of children, examining and contrasting the relative contribution of home-derived versus institutional energy and nutrient sources. The present comparison should be considered in the domain of a case-study format. The diets of 33, 3-6 y old children attending low-income day-care centers serving either 3 or a single meal were examined. The home-diet was assessed by means of 3 non-consecutive 24-hr recalls. Estimated energy and nutrient intakes at the centers and at home were assessed and related to Recommended Nutrient Intakes (RNI). Nutrient densities, critical densities and main sources of nutrients were computed. We observed that in children attending the day-care center serving three meals, home-foods contributed less than half the daily energy (47.7%) and between 29.9% and 53.5% of daily nutrients. In children receiving only lunch outside the home, energy contribution from the home was 83.9% and 304 kcal lower than for children receiving 3 meals. Furthermore, between 59.0% and 94.8% of daily nutrients were provided at home. Daily energy, nutrient intakes and nutrient densities were well above the nutrient requirements for this age group, and particularly high for vitamin A. The overall dietary variety was superior in the situation of greater contribution of home fare, but overall the nutrient density and adequacy of the aggregate intakes did not differ in any important manner.
Ingesta diaria de alimentos y nutrientes provenientes de la dieta institucional y del hogar en niños que asisten a dos centros de cuidado infantil contrastantes en la ciudad de Guatemala. Una adecuada nutrición es crítica para el desarrollo infantil. Los centros de cuidado infantiles (CCI) podrían jugar un papel fundamental en la complementación de la ingesta de alimentos y nutrientes. El propósito de este estudio fue describir la dieta de niños, comparando la contribución relativa de energía y nutrientes de la dieta-hogar e institucional. El presente estudio debe ser considerado como una presentación de caso. Se examinó la dieta de 33 niños de 3-6 años que asisten a dos CCI utilizados por familias de escasos recursos y con diferencias en número de comidas servidas. Se determinó la dieta-hogar utilizando 3 recordatorios de 24-horas en días no-consecutivos. Se calculó la ingesta estimada de energía y nutrientes en las instituciones y en casa y se comparó con las Ingestas Recomendadas de Nutrientes. Se determinó la densidad de nutrientes y principales fuentes. Se observó que los alimentos consumidos en el hogar contribuyeron 47.7% de la energía diaria y entre 29.9% y 53.5% de los nutrientes diarios requeridos para los niños con 3 comidas en el CCI y de 83.9%, 59.0 y 94.8%, respectivamente, para los niños que consumen únicamente el almuerzo en el CCI. La ingesta diaria de energía fue 304 kcal mayor en los niños que consumieron 3 comidas fuera del hogar. No hubo mayor variación en las dietas cuando mayor era el consumo de alimentos en el hogar, sin embargo la densidad nutricional y la adecuación de la dieta completa fue adecuada en ambos centros, y particularmente elevadas para la vitamina A.

Blue Rubber Bleb Nevus Syndrome (BRBS) is a rare disease, characterized by multiple vascular malformations in the skin and gastrointestinal tract. Other organs can also be affected, presenting different clinical manifestations such as arthralgia, epistaxis, hemoptysis, hematuria, hemothorax, mild thrombocytopenia, consumptive coagulopathy, and bone deformities, among others. We present a case of BRBS in a nine-year-old boy with the characteristic clinical manifestations of punctated purplish-blue skin lesions that vary in size and gastrointestinal vascular malformations with upper digestive tract bleeding.

A novel parasitoid ciliate, Pseudocollinia brintoni gen. nov., sp. nov. was discovered infecting the subtropical sac-spawning euphausiid Nyctiphanes simplex off both coasts of the Baja California peninsula, Mexico. We used microscopic, and genetic information to describe this species throughout most of its life cycle. Pseudocollinia is distinguished from other Colliniidae genera because it exclusively infects euphausiids, has a polymorphic life cycle, and has a small cone-shaped oral cavity whose left wall has a field of ciliated kinetosomes and whose opening is surrounded on the left and right by 2 'oral' kineties (or ciliary rows) that terminate at its anterior border. Two related species that infect different euphausiid species from higher latitudes in the northeastern Pacific Ocean, Collinia beringensis Capriulo and Small, 1986, briefly redescribed herein, and Collinia oregonensis Gómez-Gutiérrez, Peterson, and Morado, 2006, are transferred to the genus Pseudocollinia. P. brintoni has between 12 and 18 somatic kineties, and its oral cavity has only 2 oral kineties, while P. beringensis comb. nov. has more somatic kineties, including 3 oral kineties. P. oregonensis comb. nov. has an intermediate number of somatic kineties. P. beringensis comb. nov. also infects Thysanoessa raschi (a new host species). SSU rRNA and cox1 gene sequences demonstrated that Pseudocollinia ciliates are apostome ciliates and that P. brintoni is different from P. beringensis comb. nov. High densities of rod-shaped bacteria (1.7 µm length, 0.2 to 0.5 µm diameter) were associated with P. brintoni. After euphausiid rupture, high concentrations of P. brintoni and bacteria cluster to form 3 to 6 cm long filaments where tomites encyst and transform to the phoront stage; this is a novel place for encystation. P. brintoni may complete its life cycle when the euphausiids feed on these filaments.
