Human T-lymphotropic virus type 1 (HTLV-1) infection may cause serious disease, while pathogenicity of HTLV-2 is less certain. There are no screening or surveillance programs for HTLV-1/-2 infection in Brazil. By performing this systematic review, we aimed to estimate the prevalence of HTLV-1/-2 infections in pregnant women in Brazil. This review included cohort and cross-sectional studies that assessed the presence of either HTLV-1/-2 infection in pregnant women in Brazil. We searched BVS/LILACS, Cochrane Library/CENTRAL, EMBASE, PubMed/MEDLINE, Scopus, Web of Science and gray literature from inception to August 2020. We identified 246 records in total. Twenty-six of those were included in the qualitative synthesis, while 17 of them were included in the meta-analysis. The prevalence of HTLV-1 in Brazilian pregnant women, as diagnosed by a positive screening test and a subsequent positive confirmatory test, was 0.32% (95% CI 0.19-1.54), while of HTLV-2 was 0.04% (95% CI 0.02-0.08). Subgroup analysis by region showed the highest prevalence in the Northeast region (0.60%; 95% CI 0.37-0.97) for HTLV-1 and in the South region (0.16%; 95% CI 0.02-1.10) for HTLV-2. The prevalence of HTLV-1 is much higher than HTLV-2 infection in pregnant Brazilian women with important differences between regions. The prevalence of both HTLV-1/-2 are higher in the Northeast compared to Center-West region.

Objective: There is no evidence to suggest that an association exists between the remnant cholesterol (RC) to high-density lipoprotein cholesterol (HDL-C) ratio and gestational diabetes mellitus (GDM). In this study, the RC/HDL-C ratio during the first trimester was examined as a potential indicator of the onset of GDM during the second trimester.

Methods: This was a secondary analysis of data from a Korea-based prospective cohort study.

Background: Endoplasmic reticulum stress with protein misfolding has been introduced as a key pathogenetic mechanism in lupus nephritis (LN). Pregnancy is thought to exaggerate proteostasis, which leads to the accumulation of potentially pathogenic misfolded proteins in the urine, serum, and placenta particularly in women with preeclampsia. The detection of misfolded proteins is made using Congo red stain, which is referred to as congophilia.

Objective: This study sought to estimate population level prevalence of infertility and explored whether time to pregnancy is related to selected factors.

Methods: This study's analysis was based on data collected from 2081 women who were sampled from participants of the 2016 Ethiopia Demographic and Health Survey based on risk of pregnancy criteria: age between 15 and 49 years, currently married or cohabitating, sexually active, not used contraception method during the 5 years before interview, not menopausal, and not pregnant. We used a current duration (CD) approach in which for each woman we calculated the length of time-at-risk of pregnancy (CD value) in months.

Division of Maternal-Fetal-Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, United States.

Background: Genetic screening has advanced from prenatal cell-free DNA (cfDNA) screening for aneuploidies (cfDNA-ANP) to single-gene disorders (cfDNA-SGD). Clinical validation studies have been promising in pregnancies with anomalies but are limited in the general population.

Methods: Chart review and laboratory data identified pregnancies with cfDNA-SGD screening for 25 autosomal dominant conditions at our academic center.

This study determines video's effect on pregnant women's pain, anxiety, and perception of labor using virtual reality glasses during the active and transition phases of childbirth. This randomized controlled study was conducted with 60 pregnant women (30 in each group) admitted to the delivery room of a hospital. The data were collected by personal information form, visual comparison scale-pain, visual comparison scale-anxiety, and perception of birth scale.
