A Retrospective Cross-Sectional Analysis of Viral SARI in Pregnant Women in Southern Brazil.

Pregnant women (PW) are at a higher risk of diseases and hospitalization from viral respiratory infections, particularly influenza and SARS-CoV-2, due to cardiopulmonary and immunological changes.

Background: COVID-19 is an infectious pathology that shows vascular changes during pregnancy, as well as in the placentas. The main objectives of this study were to estimate the prevalence and the risk factors for preeclampsia in hospitalized pregnant women with COVID-19. As well as comparing maternal and perinatal outcomes in hospitalized pregnant women with COVID-19 and preeclampsia with those without preeclampsia.

Diagnosis and treatment of infectious vaginitis: Proposal for a new algorithm.

Background: Vaginitis is the most common gynecologic diagnosis in primary care, and most women have at least one episode during their lives. The need for standardized strategies to diagnose and treat vaginitis, both in primary care and among gynecologists, is emphasized. The Brazilian Group for Vaginal Infections (GBIV, acronym in Portuguese) aimed to update the practical approach to affected women by reviewing and discussing recent literature, and developing algorithms for diagnosis and treatment of vaginitis.

HELLP syndrome and COVID-19: A minor revision of a possible new "COVID-19-linked HELLP-like syndrome".

To report the characteristics described in the literature on a possible new "COVID-19-linked HELLP-like syndrome" in pregnant women with COVID-19: its association with the severity; prevalence; clinical; laboratory; pathophysiological and therapeutic management differences from the classic HELLP syndrome and their impact on outcomes. Observational, cohort, case-control, case-series and case-report studies were included. Data were extracted independently by the authors of the study, to ensure accuracy, consistency and performed the quality assessment.

Recurrence in Cervical High-Grade Squamous Intraepithelial Lesion: The Role of the Excised Endocervical Canal Length-Analysis of 2,427 Patients.

Objective: This study aimed to evaluate the influence of the excised canal length on relapse rates of cervical high-grade squamous intraepithelial lesion (HSIL) treated by loop electrosurgical excision procedure and to find a cut-off point, above which lower recurrence rates could be observed, with low probability of compromising future obstetric outcome, and the relationship with other individual factors related to HSIL recurrence.

Method: This was a retrospective cohort study of 2,427 women diagnosed with cervical intraepithelial neoplasia CIN2+ who underwent cervical conization using the high-frequency loop electrosurgical excision procedure surgery technique, to analyze the role of endocervical canal length associated with individual factors in the recurrent disease after CIN2+ treatment and determine a cut-off point for the excised canal length needed to decrease the risk of disease relapse.

Results: In 2,427 cases, the relapse rate of HSIL treated was 12%.

Comparison of two microscopic interpretations of vaginal microbiota with molecular profiling.

Objective: To compare the diagnosis of bacterial vaginosis (BV) by Nugent scoring criteria (Nugent-BV) and the diagnosis of BV and/or aerobic vaginitis (AV) using Donders criteria (Donders-BV/AV) for identifying Molecular-BV detected by bacterial 16s rRNA profiling.

Methods: We enrolled 512 women of reproductive age in Brazil with data available on Nugent and Donders microscopic analysis and 16S rRNA sequencing. We constructed receiver operating characteristic (ROC) curves of Nugent-BV and Donders-BV/AV and calculated their area under the curves (AUCs) and 95% confidence interval (CI) for matching Molecular-BV.

Analysis of the Correlation/Agreement of Maternal-fetal Doppler Parameters in Normal and Growth-Restricted Fetuses.

Methods:  The present observational and retrospective study included 274 singleton pregnancies. The following maternal-fetal Doppler parameters were assessed: uterine artery (UAt), umbilical artery (UA), middle cerebral artery (MCA), cerebroplacental ratio (CPR), and umbilical-cerebral ratio (U/C).

Vaginal Microbiome Components as Correlates of Cervical Human Papillomavirus Infection.

Background: Interplay between vaginal microbiome and human papillomavirus (HPV) remains unclear, partly due to heterogeneity of microbiota.

Methods: We used data from 546 women enrolled in a cross-sectional study in 5 Brazil. We genotyped vaginal samples for HPV and sequenced V3-V4 region of 16S rRNA gene for vaginal microbiome analysis.

Inside the pocket: Critical elements of HLA-mediated susceptibility to cervical precancerous lesions.

Human papillomavirus (HPV) infection is a necessary cause for cervical cancer (CC), but it also depends on genetic factors, such as HLA polymorphism. However, few reports addressed the role of amino acids residues at the HLA peptide-binding cleft in HPV-related cervical disease. Therefore, we aimed to investigate the association between HLA-B, HLA-C, and HLA-DRB1 polymorphism and amino acid residues composing the pockets of the peptide-binding cleft of the respective polypeptide chains with cervical intraepithelial neoplasia (CIN II/III).

Association Between COVID-19 Pregnant Women Symptoms Severity and Placental Morphologic Features.

Unlabelled: Since the beginning of the pandemic, few papers describe the placenta's morphological and morphometrical features in SARS-CoV-2-positive pregnant women. Alterations, such as low placental weight, accelerated villous maturation, decidual vasculopathy, infarcts, thrombosis of fetal placental vessels, and chronic histiocytic intervillositis (CHI), have been described.

Objective: To analyze clinical data and the placental morphological and morphometric changes of pregnant women infected with SARS-CoV-2 (COVID-19 group) in comparison with the placentas of non-infected pregnant women, matched for maternal age and comorbidities, besides gestational age of delivery (Control group).

Ethnoracial, behavioral, and environmental factors can influence microbiome. The Brazilian population is unique in terms of miscegenation of ethnic groups and behavioral characteristics across different regions.

MICA and KLRK1 genes and their impact in cervical intraepithelial neoplasia development in the southern Brazilian population.

Cervical carcinoma and cervical intraepithelial neoplasia (CIN) are associated with persistent infection by oncogenic subtypes of HPV (Human Papillomavirus). Factors linked to immunity, genetics and others like oral contraceptive use, sexual behavior, coinfections with other microorganisms and smoking seem to influence the mechanisms that determine regression or progression to CIN and cervical cancer. We investigated the effect of the MHC class I chain-related gene A (MICA) and Killer Cell Lectin Like receptor K1 (KLRK1) genes on cervical cancer and CIN lesions susceptibility in a group of 195 patients from southern Brazil.
