Maternal Risk Factors Associated with Negative COVID-19 Outcomes and Their Relation to Socioeconomic Indicators in Brazil.

BACKGROUND: This study aimed to analyze maternal risk factors associated with negative outcomes of COVID-19 and association with socioeconomic indicators in Brazil. METHODS: A cross-sectional study, with data from the Influenza Epidemiological Surveillance Information System (SIVEP-Flu) of pregnant women with COVID-19 and cases of hospitalization and death. For the analysis of risk factors and outcomes, the multiple logistic regression method was used. RESULTS: Pregnant women who had some risk factor represented 47.04%. The chance of death was 2.48 times greater when there was a risk factor, 1.55 for ICU admission and 1.43 for use of ventilatory support. The percentage of cure was 79.64%, 15.46% without any negative outcome, 4.65% death and 0.26% death from other causes. Pregnant women who did not take the vaccine represented 30.08%, 16.74% took it and 53.18% were not specified. The variables HDI, illiteracy, per capita income and urbanization did not influence the cases of COVID-19. CONCLUSIONS: Factors such as age, obesity, asthma and pregnancy were responsible for the increase in hospitalizations, respiratory complications and death. Vaccination reduced the risk of negative outcomes by 50%. There were no correlations between socioeconomic indicators and the negative outcomes of COVID-19 in pregnant women.

Factors associated with vaccination against Covid-19 in pregnant and hospitalized postpartum women: A retrospective cohort study.

OBJECTIVE: To analyze the characteristics associated with vaccination against Covid-19 in pregnant and postpartum women with Severe Acute Respiratory Syndrome in Brazil and to investigate a possible association between vaccination and the clinical course and outcome of the disease. METHODS: Retrospective cohort study of hospitalized pregnant and postpartum women diagnosed with Severe Acute Respiratory Syndrome (SARS) by SARS-CoV-2, presenting onset of signs and symptoms between May and October 2021. Secondary data were used, available in the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe). Data were analyzed using the SPSS statistical program, medians were applied to present continuous variables and frequencies, and proportions were calculated for categorical variables, using logistic and multivariate regression analysis. RESULTS: The final study population included 3,585 pregnant and postpartum women, of whom 596 (16.6) were vaccinated: 443 (74.3%) received one dose and 153 (25.7%) received two doses. They were factors associated with non-vaccination against Covid-19 age ≤ 19 anos (OR: 2.57; IC95% 1.40;4.71), non-white women (OR: 1.34; IC95% 1.07;1.67) and those who required ventilatory support (OR: 1.51; IC95% 1.19;1.90) and invasive ventilation (OR: 2.05; IC95% 1.37;3.08). On the other hand, vaccination was associated with advanced maternal age (OR: 0.60; IC95% 0.48;0.76), presence of comorbidities (OR: 0.57; IC95% 0.45;0.72) and loss of taste (OR: 0.63; IC95% 0.48;0.82). CONCLUSIONS: Demographic, ethnic-racial and clinical characteristics were associated with the vaccination status of pregnant and postpartum women with SARS by SARS-CoV-2 in Brazil. Vaccination against Covid-19 in the obstetric population has already shown positive results in the evolution of severe cases, which reiterates its importance. It is essential that health services advance vaccination against Covid-19 in the obstetric population, especially adolescentes and non-white women.

Cervical and oral human papillomavirus infection in women living with human immunodeficiency virus (HIV) and matched HIV-negative controls in Brazil.

BACKGROUND: Despite the demonstrated role of human Papillomavirus (HPV) in the etiology of cervical cancer and the strong evidence suggesting the importance of HPV in the development of oropharyngeal cancer, several aspects of the interrelationship between HPV infection in both body sites remain unknown, specifically in female human immunodeficiency virus (HIV)-positive (HIV+) patients. We aimed to assess the prevalence, distribution, and concordance of cervical and oral HPV in HIV+ women and matched HIV-negative (HIV-) controls in Brazil. MATERIAL AND METHODS: Cervical and endocervical samples for cytological screening and HPV detection and oral samples were collected from 115 HIV+ women using highly active antiretroviral therapy (HAART) and 139 HIV-matched controls (HIV-) in Maringá City, Brazil. Risk factors were assessed using a standardized questionnaire, and the data regarding HIV infection were obtained from the patients' medical records. HPV detection and typing were performed using the Kit Multiplex XGEN Multi HPV Chip HS12. RESULTS: HIV infection was well controlled in this cohort, but women who exhibited detectable HIV loads were significantly associated with HPV-positive status overall (P = 0.03) and in cervical mucosa (P = 0.01). HIV+ women had significantly more abnormal cytological findings (P = 0.04) than HIV- women. Of the 115 HIV+ women, 48.7% were positive for cervical and/or oral HPV DNA; of the 139 HIV- women, 41% were positive for cervical and/or oral HPV (P = 0.25). Both HIV+ and HIV- women had a statistically higher prevalence of cervical HPV infection than oral infection. The concurrent HPV infection in two anatomical sites was similar in HIV+ and HIV- women; however, HPV type concordance was not observed. HPV type distribution was different between the anatomical sites in both groups, and HIV+ women presented less common types, mainly in oral mucosa. CONCLUSION: Our data support the importance of testing HPV infection in HIV+ women, even when the HIV infection is well controlled. Prospective studies are required to better understand the natural history of HPV infection in both anatomical sites, specifically in HIV+ women.
