Absolute Lymphocyte Count: a Predictor of Positive Serum PCR for Trypanosoma cruzi in Patients with Chagas Disease Undergoing Heart Transplantation.

Background: It is unknown whether lymphopenia is a risk factor for the reactivation of Chagas disease in heart transplantation (HTx), as recently described in the reactivation of cytomegalovirus in transplant patients.

Objective: To evaluate whether lymphopenia in the perioperative period of heart transplantation is related to early Trypanosoma cruzi parasitemia.

Methods: This observational, retrospective study analyzed a sample from January 2014 to January 2023).

Long Covid as an Indication for Heart Transplantation and Its Characteristics.

Background: The post-acute cardiovascular manifestations of COVID-19, known as long COVID, have yet to be comprehensively characterized. There is also an increased risk of heart failure in individuals without cardiovascular disease before SARS-CoV-2 infection. The literature lacks information regarding the characteristics of patients with long COVID who developed advanced heart failure refractory to guideline-directed medical therapy.

High prevalence of clindamycin resistance in blood culture isolates in São Paulo, Brazil.

Background: Clindamycin has become an important antimicrobial option for the treatment of . However, little is known about the current patterns of clindamycin-susceptibility in invasive isolates, both in our country and in other developing countries in the world.

Aims: The aim of this study was to determine the prevalence of constitutive and inducible clindamycin resistance in methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) blood culture isolates in São Paulo, Brazil.
