A Novel Method for Involving Women of Color at High Risk for Preterm Birth in Research Priority Setting
0 Views •
Cited by 40 •
2018
This manuscript describes the Research Prioritization by Affected Communities (RPAC) protocol and findings from its use with women at risk for preterm birth. Using the protocol, women identified and prioritized their unanswered questions about pregnancy, birth and neonatal care aimed at influencing research priority setting by funders and researchers.

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...

Preterm birth (delivery < 37 weeks) is an urgent global health issue with suboptimal prevention and treatment options. We present a mouse model of ascending vaginal bacterial infection-induced preterm birth and outline how to analyze the resulting neonatal morbidity and mortality.

This manuscript describes an in vitro ovule cultivation method that enables live-cell imaging of Arabidopsis zygotes and embryos. This method is utilized to visualize the intracellular dynamics during zygote polarization and the cell fate specification in developing embryos.
FAQs
Observable signs of life provide a consistent clinical basis for recording the outcome of a delivery. Breathing, heartbeat, or voluntary movement supports classification as a live birth, while gestational age does not determine that classification. Consistent recording improves the reliability of medical documentation and population-level analyses of pregnancy and newborn outcomes.
Uterine contractions generate the force that advances labor, while cervical dilation creates the passage needed for delivery. Their coordination links the progression of labor with fetal expulsion. Clinically, this relationship helps place the delivery within the intrapartum period, when care teams monitor labor and evaluate how pregnancy progresses toward birth.
Neonatal transition is significant because the newborn must move from fetal support during pregnancy to independent breathing and circulation after delivery. This change represents an important stage in the outcome of labor and birth. In medicine, recognizing this transition connects delivery records with assessment of newborn health and perinatal care.
Aggregated live-birth data can describe fertility patterns, pregnancy outcomes, maternal health, and newborn health across populations. When examined over time, these records also show population trends. This broad perspective helps researchers and health systems evaluate whether reproductive and neonatal outcomes are changing and where additional attention may be needed.
Clinicians and researchers use live-birth records to monitor outcomes associated with care before and during labor. Comparing these records across settings or time can support evaluation of prenatal management, intrapartum care, and perinatal risks. The resulting information can guide health-service planning and help identify areas requiring closer clinical review.
When live-birth information is examined across populations, it can reveal differences in reproductive outcomes, maternal health, and newborn health. Identifying these disparities gives researchers and health services a basis for targeted evaluation rather than relying only on overall averages. The findings can inform monitoring priorities and planning for reproductive and neonatal care.
Live-birth data support questions about how frequently births occur, how pregnancy outcomes vary, and how maternal or newborn health changes across populations. In clinical research, the records help assess perinatal risks and evaluate care. In health planning, they provide evidence for allocating services and monitoring reproductive and neonatal outcomes.
