RESUMEN

PURPOSE: We aim to describe the action plan and clinical results of a COVID-19 unit for adult patient care in units intended for critically ill children, proposing a clinical/administrative framework. METHODS: We reviewed the preparedness of the PICU team before the surge of cases of COVID-19 and the organizational/administrative issues to increase critical beds in a six-bed PICU allocated to adult critical care in a government-funded general hospital in Latin America. We analyzed the prospectively collected administrative/clinical data of severe COVID-19 cases admitted to PICU during the peak of the first wave of the pandemic. RESULTS: We describe a 6-step preparedness plan: recruitment and education, admission criteria, children diversion, team hierarchy, and general and respiratory equipment. The 6-bed PICU was allocated to adult care for 20 weeks, progressively increasing capacity to a 23-bed dedicated COVID-19 unit managed by the PICU team. A six-block bed organizational units were implemented, and personnel increased from 40 to 125 healthcare workers in 24 h shifts. COVID-19 incidence in personnel was 0.5/1000 workdays. One hundred thirty-six patients were admitted, median age 59 (51,65) years old, 68% were male, and 63% had P/F ≤ 100. In addition, 48% received mechanical ventilation, the median length of stay was 7 (3,17), and in-hospital mortality was 15%. CONCLUSIONS: We propose an organizational framework for the role of PICU in the hospital action plan to increase adult critical beds. The cohort of patients admitted to a PICU repurposed as a COVID-19 ICU had good outcomes. These data are valuable to plan coordinated actions of the healthcare system for future scenarios.

RESUMEN

To evaluate the effects of nutritional supplements on nitrogen and energy balances, body composition and immune parameters, HIV-infected malnourished adult outpatients were prospectively studied. Forty-six patients (4 females and 42 males; 37 +/- 12 y) were supplemented with a polymeric diet (PD) or regular foods (RF) on two consecutive 45-day periods on a crossover design. Weight, skinfold thicknesses, plasma albumin (PA), CD4 and CD8 lymphocyte counts (LC), resting energy expenditure (REE) and urinary nitrogen excretion were measured at baseline, 45 and 90-day. Food intake was weekly recorded by food surveys. Thirty-five patients completed the protocol (18 in Group 1:PD-->RF; 17 in Group 2:RF-->PD). In both groups, weight, fat free mass (FFM), energy balance (EB) and nitrogen balance (NB) increased significantly after PD, whereas LC and PA remained unchanged in both groups. The best results in terms of weight gain were obtained in the PD group and PD plus zidovudine subgroup (n = 8) during the first 45 days (weight gain/FFM gain: 4.8/2.6 kg and 6.8/3.1 kg, respectively). Nutritional supplement with PD, according to the EB and NB goals, was well tolerated and permitted to achieve a significant weight and FFM gain over a 90-day follow-up.

RESUMEN

La nutrición parental periférica (NPP) es una técnica por medio de la cual soluciones nutricionales son infundidas a travéz de venas periféricas, condicionando una asistencia nutricional completa o parcial, evitando la colocación de un catéter venoso central. Esto último es su mayor ventaja. Sin embargo, la nutrición parental periférica tiene ciertas limitaciones y ostenta algunas complicaciones ocasionalmente, entre las cuales la mas importante es la tromboflebitis. En esta revisión se discuten y analizan los factores responsables de estas tromboflebitis iatrogénicas y las medidas y recomendaciones para prevenirlas

RESUMEN

La pancreatitis aguda es una entidad frecuente en nuestro medio. La enfermedad biliar es la causa principal en el desencadenamiento de ella. La evolución de la pancreatitis aguda puede adquirir diferentes formas clínicas que se relacionan con el pronóstico. Se proponen factores pronósticos de la enfermedad tanto desde el punto de vista clínico, de laboratorio y de imagenología. Se analizan los tratamientos actuales y conductas terapéuticas
