Uncovering moderators of pain perception by women with endometriosis from Latin America and Spain: the roles of sociodemographics, racial self-identity, and pain catastrophizing.

A cross-sectional multinational collaborative study on women with endometriosis from Latin America and Spain uncovered high levels of painful symptomatology and high pain catastrophizing scores. Associations between pain perception/catastrophizing and race/ethnicity have been documented. This study was conducted to uncover factors moderating pelvic pain severity, including socioeconomic variables, self-identified race, and pain catastrophizing in women with endometriosis from Latin America and Spain, a population encompassing diverse racial and sociocultural contexts.

Ibero-American Endometriosis Patient Phenome: Demographics, Obstetric-Gynecologic Traits, and Symptomatology.

An international collaborative study was conducted to determine the demographic and clinical profiles of Hispanic/Latinx endometriosis patients from Latin America and Spain using the Minimal Clinical Questionnaire developed by the World Endometriosis Research Foundation (WERF) Endometriosis Phenome and Biobanking Harmonization Project (EPHect). This is a cross-sectional study to collect self-reported data on demographics, lifestyle, and endometriosis symptoms of Hispanic/Latinx endometriosis patients from April 2019 to February 2020. The EPHect Minimal Clinical Questionnaire (EPQ-M) was translated into Spanish.

Zika Virus in Semen: What We Know and What We Need to Know.

The emergence of the Zika virus (ZIKV) epidemic in South and Central America has ascended to the forefront of international attention. While research regarding the effects and details surrounding ZIKV in pregnancy is well underway, especially related to blood-borne transmission, less attention has been devoted to ZIKV infection in semen and questions concerning implications of ZIKV infection in men. In this review, we present what is known and unknown, and the implications for localization of ZIKV to the male urogenital system.

Estimating Contraceptive Needs and Increasing Access to Contraception in Response to the Zika Virus Disease Outbreak--Puerto Rico, 2016.

Zika virus is a flavivirus transmitted primarily by Aedes species mosquitoes. Increasing evidence links Zika virus infection during pregnancy to adverse pregnancy and birth outcomes, including pregnancy loss, intrauterine growth restriction, eye defects, congenital brain abnormalities, and other fetal abnormalities. The virus has also been determined to be sexually transmitted.

Reduction of mouse egg surface integrin alpha9 subunit (ITGA9) reduces the egg's ability to support sperm-egg binding and fusion.

The involvement of egg integrins in mammalian sperm-egg interactions has been controversial, with data from integrin inhibitor studies contrasting with evidence from knockouts showing that specific integrin subunits are not essential for fertility. An alpha(4)/alpha(9) (ITGA4/ITGA9) integrin subfamily member has been implicated in fertilization but not extensively examined, so we tested the following three hypotheses: 1) an ITGA4/ITGA9 integrin participates in sperm-egg interactions, 2) short-term acute knockdown by RNA interference of integrin subunits would result in a fertilization phenotype differing from that of chronic depletion via knockout, and 3) detection of a fertilization phenotype is sensitive to in vitro fertilization (IVF) assay conditions. We show that mouse and human eggs express the alpha(9) integrin subunit (ITGA9).

Fine tuning cycle day 3 hormonal assessment of ovarian reserve improves in vitro fertilization outcome in gonadotropin-releasing hormone antagonist cycles.

Objective: To identify the cut-off values of the baseline (cycle day 3) levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E(2)) for improving the outcome prediction of GnRH antagonist in vitro fertilization (IVF) cycles and to determine whether the predictive accuracy of these values is affected by the patient's clinical prognosis.

Design: Retrospective analysis.

Setting: An IVF clinic in a tertiary medical center.

Clinical outcome of using ganirelix acetate versus a 4-day follicular phase leuprolide acetate protocol in unselected women undergoing in vitro fertilization.

Objective: To compare the clinical outcome of controlled ovarian hyperstimulation (COH) in unselected patients undergoing IVF using multidose ganirelix acetate versus 4 days of administration of leuprolide acetate.

Design: Retrospective cohort study.

Setting: A fertility and IVF center.
