  1. Ongoing host-shift speciation in Plasmodium simium

    TRENDS IN PARASITOLOGY, v.37, n.11, p.940-942, 2021

    Plasmodium simium, a malaria parasite that infects platyrrhine monkeys and humans in the New World, is nearly identical to Plasmodium vivax. Recent genomic comparative analyses of these sister species have identified elevated divergence in a gene that may underlie P. simium adaptation to non-huma...

  2. Four Corners: an educational strategy for learning infectious diseases in medical school

    REVISTA BRASILEIRA DE EDUCAçãO MéDICA, v.45, n.3, p.e142, 2021

    Abstract: Introduction: An extensive literature has demonstrated the benefits of active learning in medical education and has revealed the need for updating the teaching methodologies. Active learning strategies consolidate the theoretical knowledge, while simultaneously encouraging the student´s...

  3. Residual malaria of Atlantic Forest systems and the influence of anopheline fauna

    PARASITOLOGY RESEARCH, v.120, n.8, p.2759-2767, 2021

    In Brazil, the Amazon region comprises 99.5% of the reported malaria cases. However, another hotspot of the disease is the Atlantic Forest regions, with the sporadic occurrence of autochthonous human cases. In such context, this study sought to investigate the role of anopheline mosquitoes (Dipte...

  4. Neurological manifestations in people living with HIV/AIDS in the late cART era: a prospective observational study at a tertiary healthcare center in Sao Paulo, Brazil

    HIV RESEARCH & CLINICAL PRACTICE, v.22, n.4, p.87-95, 2021

    Background:The aim of this study was to evaluate the frequency, spectrum, in-hospital mortality rate, and factors associated with death in people living with HIV/AIDS (PLWHA) presenting with neurological diseases from a middle-income country, as well as estimate its one-year global death rate. Me...

  5. Surveillance of post-cataract endophthalmitis at a tertiary referral center: a 10-year critical evaluation

    INTERNATIONAL JOURNAL OF RETINA AND VITREOUS, v.7, n.1, article ID 14, 6p, 2021

    BackgroundAcute post-cataract endophthalmitis (APE) is a rare complication potentially causing irreversible visual loss. A 10-year study of APE was conducted to determine its incidence, microbiological spectra and antibiotic resistance profile of APE-related pathogens at a major tertiary referral...

  6. Combining urine antigen and blood polymerase chain reaction for the diagnosis of disseminated histoplasmosis in hospitalized patients with advanced HIV disease

    MEDICAL MYCOLOGY, v.59, n.9, p.916-922, 2021

    Disseminated histoplasmosis (DH) is endemic in Latin America and the Caribbean where diagnostic tools are restricted. We carried-out a 1-year prospective cohort study at a referral hospital in SAo Paulo, Brazil. Participants had > or =18 years old, were hospitalized due to any indication and had ...

  7. Tocilizumab in SARS-COVID19 following postoperative laparoscopic transhiatal esophagectomy for the adenocarcinoma of esophagogastric tumor: A case report

    INTERNATIONAL JOURNAL OF SURGERY CASE REPORTS, v.86, article ID 106343, 4p, 2021

    Introduction and importance: Esophagectomy for esophageal cancer is one of the most challenging surgical procedures, with high rates of morbidity, especially from respiratory complications. SARS-COVID19 represents a health threat nowadays. Peri-operative SARS-COVID19 infection after esophagectomy...

  8. Loss of forest cover and host functional diversity increases prevalence of avian malaria parasites in the Atlantic Forest

    INTERNATIONAL JOURNAL FOR PARASITOLOGY, v.51, n.9, p.719-728, 2021

    Host phylogenetic relatedness and ecological similarity are thought to contribute to parasite community assembly and infection rates. However, recent landscape level anthropogenic changes may disrupt hostparasite systems by impacting functional and phylogenetic diversity of host communities. We e...

  9. Serum antibodies blocked by glycan antigens in canine visceral leishmaniasis serology are mostly IgA immune complexes

    PARASITOLOGY, v.148, n.12, p.1509-1515, 2021

    Immune complexes (ICs) are found in canine visceral leishmaniasis (CVL) and interfere with the serum detection of antibodies. Dissociation of these monovalent complexes by dissociative enzyme-linked immunosorbent assay (ELISA) removes false-negative results and allows some characterization of ant...

  10. Post-acute sequelae of SARS-CoV-2 infection (PASC): a protocol for a multidisciplinary prospective observational evaluation of a cohort of patients surviving hospitalisation in Sao Paulo, Brazil
