Hypophosphatemia and risk of refeeding syndrome in critically ill patients before and after nutritional therapy.
To investigate the prevalence of hypophosphatemia as a marker of refeeding syndrome (RFS) before and after the start of nutritional therapy (NT) in critically ill patients. ⋯ The frequency of critically ill patients with hypophosphatemia and at risk for RFS on admission is high and this risk increases after the start of NT, especially in malnourished patients and those receiving parenteral nutrition.

Gastrointestinal emergency care during the COVID-19 pandemic: rapid communication.
Social distancing during the COVID-19 pandemic has been associated with a decrease in the search for medical care. High-risk patients have avoided hospital environments fearing infection. We hypothesize that there was also a decrease in the search for medical care related to gastrointestinal emergencies. The aim of this study is to evaluate the frequency of consultations for severe gastrointestinal emergencies during and before the months of the pandemic. ⋯ This study reports a pronounced decrease in consultations for severe gastrointestinal emergencies during the pandemic. Governments and society should be aware that health crises do not halt the natural occurrence of noninfectious diseases; otherwise, an increase in mortality from these morbidities may arise.

Discriminant indexes to simplify the differential diagnosis between iron deficiency anemia and thalassemia minor in individuals with microcytic anemia.
Microcytic anemias are very common in clinical practice, with iron deficiency anemia (IDA) and thalassemia minor (TT) being the most prevalent. Diagnostic confirmation of these clinical entities requires tests involving iron metabolism profile, hemoglobin electrophoresis, and molecular analysis. In this context, several discriminant indices have been proposed to simplify the differential diagnosis between IDA and TM. ⋯ Confirmatory tests for differential diagnosis between IDA and TM require time-consuming and costly methods. Despite the excellent performances of IGK, Ehsani index, and RBC, none of them presented sufficient sensitivity and specificity to establish a diagnosis. However, they can provide a powerful additional tool for diagnostic simplification between IDA and TM.
