Measuring the burden of SARS-CoV-2 infection among persons living with HIV and healthcare workers and its impact on service delivery in Mozambique: protocol of a prospective cohort study.

INTRODUCTION: As COVID-19 continues to spread globally and within Mozambique, its impact among immunosuppressed persons, specifically persons living with HIV (PLHIV), and on the health system is unknown in the country. The 'COVid and hIV' (COVIV) study aims to investigate: (1) the seroprevalence and seroincidence of SARS-CoV-2 among PLHIV and healthcare workers providing HIV services; (2) knowledge, attitudes, practices and perceptions regarding SARS-CoV-2 infection; (3) the pandemic's impact on HIV care continuum outcomes and (4) facility level compliance with national COVID-19 guidelines. METHODS AND ANALYSIS: A multimethod study will be conducted in a maximum of 11 health facilities across Mozambique, comprising four components: (1) a cohort study among PLHIV and healthcare workers providing HIV services to determine the seroprevalence and seroincidence of SARS-CoV-2, (2) a structured survey to assess knowledge, attitudes, perceptions and practices regarding COVID-19 disease, (3) analysis of aggregated patient data to evaluate retention in HIV services among PLHIV, (4) an assessment of facility implementation of infection prevention and control measures. ETHICS AND DISSEMINATION: Ethical approval was obtained from the National Health Bioethics Committee, and institutional review boards of implementing partners. Study findings will be discussed with local and national health authorities and key stakeholders and will be disseminated in clinical and scientific forums. TRIAL REGISTRATION NUMBER: NCT05022407.

Saúde bucal da crianças de Goiânia: prevalência de doença gengival e presença de espiroquetas em placa subgengival de 300 crianças de 2 a 11 anos de idade com baixa condição socioeconômica / Children's oral health in Goiânia: prevalence of gingivitis disease and presence of spiroquets in subgengival plaque of 300 children aged 2-11 years with low social economic condition

A proposta desta investigação foi determinar a associação de gengivite - espiroquetas em placa subgengival de 300 crianças de 2 a 11 anos, com baixa condição socioecônomica, matriculadas em creches e escolas dos bairros da periferia de Goiânia. Materail e Método - As amostras subgengivais de 1.200 sítios, correspondendo a 4 sítios por criança, foram colhidas por intermédio de palitos de madeira e coradas pelo método de Fontana-Tribondeau para detectar a presença de espiroquetas. Para a análise clínica gengival foi aplicada a classificação do índice gengival (IG) segundo Loe. Resultados - Os dados mostraram que 53,75% das amostras apresentaram espiroquetas, sendo mais prevalentes nas crianças do sexo masculino. Os resultados foram submetidos à análise estatística de qui-quadrado com grau de significância de 5% e a frequência relativa observada de espiroquetas em função da variável idade, sugere uma tedência crescente estatisticamente significativa. Nas idades de 2-3 anos foi de 45,84%; 4-5 anos 51,27%; 6-7 anos 54,41%; 8-9 anos 54,84% e de 10-11 anos 70%. A idade das crianças também, influenciou de forma crescente quanto às proporções de espiroquetas em função dos sítios sangrantes das gengivas, com uma maior prevalência de 77,23% na faixa etária de 10-11 anos. Conclusão - A análise estatística da associação de espiroquetas em sítios sangrantes das gengivas com 94,69% em relação a não sangrantes sugere que essa correlação pode ser utilizada em crianças de baixa condição econômica como indicador de futuro dano periodontal.
