Objective: To evaluate the role of being human immunodeficiency virus (HIV) positive for predicting the risk of recurrence in women with a cervical high grade squamous intraepithelial lesion (HSIL) diagnosis.

Methods: Retrospective observational case-control study, comprising HIV positive (case) and HIV negative (control) women in a 1:4 ratio. Women assisted by the Erasto Gaertner Hospital, between 2009-2018, with cervical HSIL diagnosis, submitted to treatment by Loop electrosurgical excision procedure (LEEP), and with a minimum follow-up of 18 months, were included.

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. This study assessed the impact of viral respiratory infections on PW hospitalized with severe acute respiratory infection (SARI) prior to the COVID-19 pandemic. It is a cross-sectional study with 42 PW and 85 non-pregnant women (NPW) admitted with SARI to two tertiary hospitals between January 2015 and December 2019.

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.

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).

Characterization of the Vaginal Microbiome in Women of Reproductive Age From 5 Regions in Brazil.

Background: Composition of the vaginal microbiome is strongly related to a woman's reproductive health and risk of sexually transmitted infections. 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.

Mycoplasma genitalium, a stealth female reproductive tract.

Mycoplasma genitalium was first isolated from the urethral swabs of two symptomatic men with urethritis in 1980. It is a sexually transmitted bacterium associated with a number of urogenital conditions in women like cervicitis, endometritis, pelvic inflammatory disease, infertility, and susceptibility to human immunodeficiency virus (HIV). However, M.

MASP-1 and MASP-2 Serum Levels Are Associated With Worse Prognostic in Cervical Cancer Progression.

MBL-associated serine proteases (MASP-1, MASP-2, MASP-3, MAp-44, and MAp-19) are key factors in the activation of the lectin pathway of complement. Serum levels of these components have been associated with recurrence and poor survival of some types of cancer, such as colorectal and ovarian cancer. In this investigation, we determined the serum levels of MASP-1, MASP-2, MASP-3, MAp-44, and MAp-19 in patients with cervical cancer and cervical intraepithelial neoplasia (CIN).

Zika virus and pregnancy: An overview.

In May 2015, the first episodes of Zika virus infection of the Latin America were confirmed in Brazil, where currently 196 976 cases were reported. The main route of transmission occurs by Aedes mosquitoes, and the most common symptoms are maculopapular rash, fever, conjunctivitis, polyarthralgia, and periarticular edema. However, the infection is asymptomatic in 80% of the cases.

Baby born too soon: an overview and the impact beyond the infection.

Spontaneous preterm delivery, prematurity, and low birth weight due to prematurity account for a great part of neonatal morbidity and mortality. Inflammation may cause preterm labor, with the involvement of different mediators that produce diverse aspects of the inflammatory response. Although bacteria are considered to be the main trigger for intrauterine infection/inflammation, immunological factors also appear to be involved.

Zika virus infection during pregnancy and microcephaly occurrence: a review of literature and Brazilian data.
