Effect of Non-Surgical Periodontal Therapy on Clinical Parameters of Periodontitis, Oral spp. Count and Lactoferrin and Histatin Expression in Saliva and Gingival Crevicular Fluid of HIV-Infected Patients.

Background: Periodontitis (PDT) has gained attention in the literature with the increase in life expectancy of people living with HIV on combined antiretroviral therapy (cART). Thus, the search for inflammatory biomarkers could be useful to understand the pathophysiology of chronic oral diseases in the cART era.

Objective: The aim of this study was to evaluate the impact of non-surgical periodontal therapy (NSPT) on clinical parameters of PDT, Candida spp.

COVID-19 and isolation: Risks and implications in the scenario of new variants.

With the emergence of new variants of SARS-CoV-2, questions about transmissibility, vaccine efficacy, and impact on mortality are important to support decision-making in public health measures. Modifications related to transmissibility combined with the fact that much of the population has already been partially exposed to infection and/or vaccination, have stimulated recommendations to reduce the isolation period for COVID-19. However, these new guidelines have raised questions about their effectiveness in reducing contamination and minimizing impact in work environments.

Hydroxychloroquine versus placebo in the treatment of non-hospitalised patients with COVID-19 (COPE - Coalition V): A double-blind, multicentre, randomised, controlled trial.

Background: Previous Randomised controlled trials (RCT) evaluating chloroquine and hydroxychloroquine in non-hospitalised COVID-19 patients have found no significant difference in hospitalisation rates. However, low statistical power precluded definitive answers.

Methods: We conducted a multicenter, double-blind, RCT in 56 Brazilian sites.

Clinical investigation of intestinal fatty acid-binding protein (I-FABP) as a biomarker of SARS-CoV-2 infection.

Objectives: SARS-CoV-2 exhibits tropism for the gastrointestinal tract; however, lesions in enterocytes and their correlation with disease severity and patient prognosis are still unknown.

Methods: SARS-CoV-2 patients were enrolled in 5 medical centres in São Paulo, Brazil and their clinical characteristics and laboratory findings recorded. At admission, day 7 and day 14 of hospitalisation, plasma and urine samples were collected, and cytokine levels and intestinal fatty acid-binding protein (I-FABP) concentrations measured.

An analysis of face-mask performance from a volunteer mask-making initiative in Ribeirão Preto, Brazil.

Objectives: This study examines the response of a group of volunteers in Ribeirão Preto, Brazil, as the city faced an unprecedented demand for face masks during the onset of the COVID-19 crisis in 2020. The performance of artisanal-produced masks was compared with industry equivalents.

Study Design: Case report with comparative testing.

Effects of non-surgical periodontal therapy on clinical and immunological profile and oral colonization of Candida spp in HIV-infected patients with chronic periodontitis.

Background: After the introduction of antiretroviral therapy (ART), human immunodeficiency virus (HIV) infection has become a chronic controllable disease. For this reason, chronic conditions related to both HIV infection and senescence, such as chronic periodontitis (CP) need to be studied. This study investigated the impact of non-surgical periodontal therapy (NSPT) on clinical and immunological features of CP, and on oral colonization by Candida spp.

Consensus of the Brazilian Society of Infectious Diseases and Brazilian Society of Clinical Oncology on the management and treatment of Kaposi's sarcoma.

Kaposi's sarcoma is a multifocal vascular lesion of low-grade potential that is most often present in mucocutaneous sites and usually also affects lymph nodes and visceral organs. The condition may manifest through purplish lesions, flat or raised with an irregular shape, gastrointestinal bleeding due to lesions located in the digestive system, and dyspnea and hemoptysis associated with pulmonary lesions. In the early 1980s, the appearance of several cases of Kaposi's sarcoma in homosexual men was the first alarm about a newly identified epidemic, acquired immunodeficiency syndrome.

Virologic and immunologic effectiveness at 48 weeks of darunavir-ritonavir-based regimens in treatment-experienced persons living with HIV-1 infection in clinical practice: a multicenter Brazilian cohort.

Introduction: Published data addressing the effectiveness of darunavir-ritonavir (DRV/r)-based therapy for multiexperienced patients in developing countries are scarce. This study evaluated the 48-week virologic and immunologic effectiveness of salvage therapy based on DRV/r for the treatment of multidrug-experienced HIV-1-infected adults in Brazil.

Materials And Methods: A multicenter retrospective cohort study was carried out with multidrug-experienced adults who were on a failing antiretroviral therapy and started a DRV/r-based salvage therapy between 2008 and 2010.

Paracoccidioidomycosis in patients infected with and not infected with human immunodeficiency virus: a case-control study.

Epidemiologic and clinical data for 53 patients with paracoccidioidomycosis and co-infected with human immunodeficiency virus (HIV) (cases) were compared with those for 106 patients with endemic paracoccidioidomycosis (controls). The prevalence of Paracoccidioides brasiliensis co-infection was estimated in 1.4% in cases of acquired immunodeficiency syndrome (AIDS).
