Nutrition as a risk for mortality and functionality in critically ill older adults.

BACKGROUND: There is no specific recommendation for nutrition therapy for critically ill older adults. However, targeting energy and protein balance and avoiding fasting could improve outcomes in this population with high-risk nutrition outcomes. This study aimed to evaluate the associations between nutrition and mortality/functionality in critically ill older patients. METHODS: A single-center retrospective observational study of critically ill patients aged 65 years or older was conducted. We extracted data from the dietitian evaluations on energy, protein, and the type of diet (fasting, oral, enteral, or parenteral) prescribed in the first week of intensive care unit admission. Primary outcomes were intrahospital mortality and independence and functional capacity evaluated after hospital discharge. RESULTS: Of the 2043 patients screened, 533 were included in the study. Most patients were men (52.1%), with a median age of 73 (68-78) years. Overall, the intrahospital mortality rate was 53.8%. Simplified Acute Physiology Score 3 (SAPS 3), serum albumin and C-reactive protein levels, and surgical patients were independently associated with fasting in a multivariate analysis. The multivariate regression analyses showed that SAPS 3, serum albumin level, and fasting were independently associated with mortality. Each fasting day increases the risk of mortality by 16.7%. Also, independence and functional capacity were not related to nutrition prescription. CONCLUSION: Older adults (65 years or older) constitute a fragile population in whom nutrition breaks were associated with increased hospital mortality. Furthermore, a prospective clinical trial is necessary to establish the best strategy to feed this population.

Wandering spleen as a cause of sinistral portal hypertension

Wandering spleen (WS) is a rare entity characterized by laxity of peritoneal ligaments that hold the spleen stationary. It is most commonly diagnosed in children and young women. Clinical presentation ranges from asymptomatic to acute abdomen. A 19-year-old woman came to the emergency department with history of progressive abdominal pain. She also had previous episodes of hematemesis. A computed tomography scan showed an ectopic spleen with a "whirlpool sign." Laparotomy and splenectomy were performed. WS is characterized by a long vascular pedicle and laxity of peritoneal attachments of the spleen. The etiology is usually congenital. Splenopexy is the main treatment; however, splenectomy is indicated when splenic infarction is present. Despite being rare, this condition may be considered in some cases of abdominal pain. An earlier diagnosis would have allowed us to perform a splenopexy, thus reducing morbidity. (AU)
