Evaluation of galectin-3 levels in patients with type 2 diabetes mellitus and chronic kidney disease
CONCLUSION: The results suggest that Gal-3 may be involved in the pathophysiology of T2DM and still be a promising biomarker associated with hypertension in this group.RESUMEN INTRODUCCI ÓN: La diabetes mellitus tipo 2 (DM2) es la forma más común de la diabetes; representa alrededor del 90% de los casos diagnosticados. Todavía no se conocen por completo las causas de la DM2, pero posiblemente su etiopatogénesis se relaciona con el aumento de adiposidad y una respuesta inflamato ria crónica de bajo grado. Se sabe que la glicoproteína galectina 3 (Gal-3) juega un papel importante en la modulación de glucemia, adipos...

Coronavirus in a patient with hepatitis C: case report
ABSTRACT In February 2020, the World Health Organization (WHO) named the infection with the new coronavirus, which appeared in December 2019 in China, as Covid-19, and defined it as a worldwide pandemic. There is not much evidence about the relationship between liver disease and Covid-19. Laboratory tests have played a fundamental role in confirming Covid-19, what is usually done by the polymerase chain reaction (PCR) sample. The present study reports the laboratory aspects of a patient with type C hepatitis diagnosed with Covid-19 with an unfavorable evolution, devoting special attention to laboratory tests that were almo...

Coronavirus in pediatrics: report of two cases and review of the literature
ABSTRACT COVID-19 was identified on December 31, 2019 in China, and has since been the subject of several studies. In the area of pediatrics, the infection appears to affect this population group more mildly when compared to adults. The present work shows the report of two cases of in patients in the pediatric age group, both aged 2 years, presenting their laboratory, clinical and radiological aspects. In this population, the virus ’ s transmissibility seems to be related to symptom presentation, as the less symptomatic the patient presents the lower is transmissibility.

Coronavirus and the puerperium: a case report
ABSTRACT COVID-19 started in China on December 31, 2019 and has since been the subject of several studies in medical field. There is not much evidence about the pregnancy and puerperium with the susceptibility of coronavirus infection (COVID-19). The present work reports the laboratory and radiological aspects of a puerperium patient. A positive test for severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) generally confirms the diagnosis of COVID-19, although false-positive and false-negative tests are possible. The test considered the gold standard for the diagnosis of coronavirus infection (COVID-19) is from in ...
