Prediction of Prostate Cancer Disease Aggressiveness Using Bi-Parametric Mri Radiomics.

Prostate cancer is one of the most prevalent cancers in the male population. Its diagnosis and classification rely on unspecific measures such as PSA levels and DRE, followed by biopsy, where an aggressiveness level is assigned in the form of Gleason Score. Efforts have been made in the past to use radiomics coupled with machine learning to predict prostate cancer aggressiveness from clinical images, showing promising results.

Recurrent and persistent cytomegalovirus infection in a kidney recipient caused by the L595S mutation in UL97 phosphotransferase gene.

Ganciclovir (GCV) is the first therapeutic choice for prevention and treatment of active cytomegalovirus (CMV) infection in solid organ transplant recipients in Bahia state, Brazil. Prolonged and repeated GCV therapy may result in drug-resistant virus, associated with progressive and disseminated disease. We present a case report of a young male kidney recipient, who was CMV-seronegative with a CMV-seropositive donor (D(+)/R(-)), and who developed clinical GCV resistance, confirmed by mutation in viral UL97 phosphotransferase responsible for GCV activation.

Determinants of C-reactive protein in individuals with very low socioeconomic status.

Background: Low socioeconomic (SE) status has been associated to inflammation and predictors of C-reactive protein (CRP) have been investigated by studies performed in developed countries. This study aimed to identify predictors of CRP in individuals of very low SE level in a developing country and evaluate whether CRP is related to SE status in this scenario.

Objective: Eight-two individuals of very low SE level were recruited from a poor, semi-rural community in Brazil.

Quinoline compounds decrease in vitro spontaneous proliferation of peripheral blood mononuclear cells (PBMC) from human T-cell lymphotropic virus (HTLV) type-1-infected patients.

In vitro spontaneous proliferation is the immunological hallmark of peripheral blood mononuclear cells (PBMC) from HTLV-1-infected individuals. Quinoline compounds down regulate in vitro cell proliferation of HTLV-1 transformed cell lines. In the present study we assessed the capacity of quinolines to inhibit spontaneous cell proliferation of PBMC from HTLV-1-infected individuals.
