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.

Prevalence of sarcopenia in kidney transplants and their association with determinant factors of muscle homeostasis.
Sarcopenia is characterized by the involuntary loss of lean body mass associated with a progressive reduction of muscle strength. ⋯ Early diagnosis may allow the prevention of sarcopenia and provide a better quality of life for patients.

Is the COVID-19 disease associated with de novo nephritic syndrome?
This study aims to determine the incidence of de novo nephritic syndrome (NS) in COVID-19 patients and identify its associated factors. ⋯ COVID-19-induced de novo nephritic syndrome may occur mainly due to tubulointerstitial involvement and often results in spontaneous remission. However, why these findings were not present in all patients who had no comorbidities is not clear.

Tuberculosis in Northeastern Brasil (2001-2016): trend, clinical profile, and prevalence of risk factors and associated comorbidities.
To describe the temporal trend, clinical profile, and the prevalence of risk factors and associated comorbidities in new cases of tuberculosis in the Northeast (2001-2016). ⋯ Even with a reduced incidence, tuberculosis represents a real public health problem in the Northeast region. The profile was characterized by a male population, in economically-active age, lung smear-positive pulmonary presentation, and the risk factors and comorbidities of Aids, TB/HIV co-infection, diabetes mellitus, alcohol consumption, institutionalized and deprived of freedom reflect the complexity of the challenges in facing the disease.

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.
