Data-driven, cross-disciplinary collaboration: lessons learned at the largest academic health center in Latin America during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency.

Methods: At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank.

Adherence to non-pharmacological preventive measures among healthcare workers in a middle-income country during the first year of the COVID-19 pandemic: Hospital and community setting.

This study assessed, using a self-reported questionnaire, the adherence to PPE (mask, gowns, and gloves) at the workplace, as well as to non-pharmacological preventive measures (NPPM) (physical distance defined as hardly ever and/or never approaches other people within 1.5 meters, social isolation as leaving home less than once a week, hand hygiene was defined as performing hand hygiene ≥ 6 times per period, and adherence to the use of a mask outside of the workplace was defined as on all outings and hardly ever and/or never removes the mask) outside of the workplace among 1,296 health care workers (HCWs), including if NPPM adherence was associated with COVID-19 in HCWs. High adherence to PPE was independently associated with younger age, professional category, work in an area of direct patient assistance; use of public transportation, or adherence to NPPM outside of the workplace.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Seroprevalence and Risk Factors Among Oligo/Asymptomatic Healthcare Workers: Estimating the Impact of Community Transmission.

We evaluated the seroprevalence of SARS-CoV-2 and risk factors among 4987 oligo/asymptomatic healthcare workers; seroprevalence was 14% and factors associated with SARS-CoV-2 infection were lower educational level (aOR, 1.93; 95% CI, 1.03-3.

[Consensus of the Brazilian Society of Rheumatology for the diagnosis, management and treatment of lupus nephritis].

Objective: To develop recommendations for the diagnosis, management and treatment of lupus nephritis in Brazil.

Method: Extensive literature review with a selection of papers based on the strength of scientific evidence and opinion of the Commission on Systemic Lupus Erythematosus members, Brazilian Society of Rheumatology.

Results And Conclusions: 1) Renal biopsy should be performed whenever possible and if this procedure is indicated; and, when the procedure is not possible, the treatment should be guided with the inference of histologic class.

[Diagnostic methods for chloroquine diphosphate induced retinopathy in systemic lupus erythematosus].

Purpose: To evaluate different diagnostic methods for high risk chloroquine retinopathy due to prolonged use of chloroquine (more than 5 years) by systemic lupus erythematosus patients.

Methods: Seventy-two eyes of 36 consecutive patients, followed in the Division of Rheumatology, School of Medicine, University of São Paulo, were analyzed from July 2007 to April 2008. Demographic and clinical data were evaluated in order to study risk factors and to compare the following different ophthalmological methods: visual acuity, biomicroscopy, fundus examination, retinography, fluorescein angiogram, visual field test and, color vision tests.
