Early-life menstrual characteristics and gestational diabetes in a large US cohort.

Background: Associations between early-life menstrual cycle characteristics (MCC) and gestational diabetes (GDM) remain unclear.

Objectives: To evaluate associations between early-life MCCs and GDM in first pregnancy, across pregnancies and its recurrence.

Methods: This analysis included participants from a US-based digital cohort enrolled between 11/2019 and 9/2023 who provided consent, completed relevant surveys, were without diabetes and aged ≥18 at first pregnancy (n = 30,473).

Trends in sensor-based health metrics during and after pregnancy: descriptive data from the apple women's health study.

Background: While it is known that vital signs and behaviors change during pregnancy, there is limited data on timing and scale of changes for sensor-derived health metrics across pregnancy and postpartum. Wearable technology provides an opportunity to understand physiologic and behavioral changes across pregnancy with greater detail, more frequent measurements, and improved accuracy. The aim of this study is to describe changes in physiologic and behavioral sensor-based health metrics during pregnancy and postpartum in the Apple Women's Health Study (AWHS) and their relationship to demographic factors.

Covid-19 vaccination and menstrual cycle length in the Apple Women's Health Study.

COVID-19 vaccination may be associated with change in menstrual cycle length following vaccination. We estimated covariate-adjusted differences in mean cycle length (MCL), measured in days, between pre-vaccination cycles, vaccination cycles, and post-vaccination cycles within vaccinated participants who met eligibility criteria in the Apple Women's Health Study, a longitudinal mobile-application-based cohort of people in the U.S.

Piloting a Faculty Development Program in a Rural Haitian Teaching Hospital.

Background: Faculty development for nurse and physician educators has a limited evidence base in high income countries, and very little research from low- and middle-income countries. Health professions educators in many global settings do not receive training on how to educate effectively.

Objective: To pilot and assess a faculty development program aimed at nurse and physician educators at a teaching hospital in rural Haiti.

Zika Virus-Immune Plasmas from Symptomatic and Asymptomatic Individuals Enhance Zika Pathogenesis in Adult and Pregnant Mice.

Preexisting immunity against dengue virus or West Nile virus was previously reported to mediate antibody-dependent enhancement (ADE) of Zika virus (ZIKV) infection in a mouse model. We show here that ZIKV-immune plasma samples from both symptomatic and asymptomatic individuals mediated ZIKV ADE of infection and in mice. In a lethal infection model with a viral inoculum 10 times higher, both ADE and protection were observed, depending on the amount of infused immune plasma.

First Locally Acquired Congenital Zika Syndrome Case in the United States: Neonatal Clinical Manifestations.

In the spring of 2017, a full-term infant with microcephaly was delivered in South Florida. During first trimester, the mother presented with fever, nausea, and vomiting. She reported no foreign travel for herself or her partner.

Zika virus and the nonmicrocephalic fetus: why we should still worry.

Zika virus is a mosquito-transmitted flavivirus and was first linked to congenital microcephaly caused by a large outbreak in northeastern Brazil. Although the Zika virus epidemic is now in decline, pregnancies in large parts of the Americas remain at risk because of ongoing transmission and the potential for new outbreaks. This review presents why Zika virus is still a complex and worrisome public health problem with an expanding spectrum of birth defects and how Zika virus and related viruses evade the immune response to injure the fetus.

Fetal demise and failed antibody therapy during Zika virus infection of pregnant macaques.

Zika virus (ZIKV) infection of pregnant women is associated with pathologic complications of fetal development. Here, we infect pregnant rhesus macaques (Macaca mulatta) with a minimally passaged ZIKV isolate from Rio de Janeiro, where a high rate of fetal development complications was observed. The infection of pregnant macaques with this virus results in maternal viremia, virus crossing into the amniotic fluid (AF), and in utero fetal deaths.

The Utility of Social Media in Providing Information on Zika Virus.

Introduction In 2015, there was an outbreak of Zika virus in Brazil that spread throughout the Americas. The association of Zika virus with birth defects in infants born to infected pregnant women created concern for women of childbearing age. Social media is an important platform for health promotion, communication, and education on preventative methods during Zika virus outbreaks.

Zika Virus Testing and Outcomes during Pregnancy, Florida, USA, 2016.

Zika virus infection during pregnancy can lead to congenital Zika syndrome. Implementation of screening programs and interpretation of test results can be particularly challenging during ongoing local mosquitoborne transmission. We conducted a retrospective chart review of 2,327 pregnant women screened for Zika virus in Miami-Dade County, Florida, USA, during 2016.

Knowledge and perceptions of Zika virus among reproductive-aged women after public announcement of local mosquito-borne transmission.

Aim: This study was conducted to ascertain the knowledge and perceptions of the Zika virus among reproductive-aged women living in the first affected area of the United States with local mosquito-borne transmission.

Methods: Reproductive-aged women were surveyed during the four weeks immediately following the announcement of local Zika virus transmission. The survey evaluated the participant's knowledge of Zika pathogenesis and transmission, sequelae of infection, epidemiology and public health information.

A needs and resource assessment of continuing medical education in Haiti.

Background: Haiti has a chronic physician shortage, and the country has been facing an increased disease burden since the 2010 earthquake and the subsequent introduction of cholera. In such resource-challenged settings, access to postgraduate medical education often is limited due to inadequate financial, structural, and academic resources. A crucial component to improved health in Haiti is the expansion of continuing medical education (CME).

Barriers to Immediate Post-placental Intrauterine Devices among Attending Level Educators.

Objective: To determine whether barriers to immediate post-placental intrauterine device (PPIUD) placement exist at the provider level.

Study Design: Obstetrics providers at seven academic teaching hospitals in Massachusetts were asked to complete an electronic survey regarding their knowledge, experience, and opinions about immediate PPIUDs.

Results: Eighty-two providers, including obstetricians, family medicine physicians, and midwives, completed the survey.

Port-site metastases after robotic surgery for gynecologic malignancy.

Background And Objectives: Robotic-assisted laparoscopic surgery is increasingly used for the management of patients with gynecologic malignancies. The rate of portsite metastases in patients undergoing these procedures is unknown.

Methods: We conducted a retrospective cohort analysis of a prospective database.

Medical student knowledge of global health problems: obstetric fistulas in developing countries.

Objective: To evaluate medical students in the United States at several medical schools regarding their knowledge of the global health burden of obstetric fistulas.

Study Design: A cross-sectional survey was conducted in 8 schools across the United States over a period of 6 months. The survey was composed of 18 questions on epidemiology, pathology, and treatment of fistulas.
