Filter by:Vitamin D deficiency is common among otherwise healthy pregnant women and may have consequences for them as well as the early development and long-term health of their children. However, the importance of maternal vitamin D status has not been widely studied. The present study is divided into a societal experiment (1) and a case-cohort study (2): 1. The present study includes an in-depth examination of the influence of exposure to vitamin D early in life and during critical periods of growth for development of type 1 diabetes (T1D), type 2 diabetes, gestational diabetes, pre-eclampsia, obesity, asthma, arthritis, cancer, mental and cognitive disorders, congenital disorders, dental caries and bone fractures during child- and adulthood. The study is based on the fact that mandatory fortification of margarine with vitamin D, which initiated in 1937, was terminated in 1985. Apart from determining the influences of exposure prior to conception and during pre- and postnatal life, the investigators examined the importance of vitamin D exposure during specific seasons and trimesters, by comparing disease incidence among individuals born before and after the fortification. 2. Additionally, a validated method was used to determine neonatal vitamin D status using stored dried blood spots (DBS) from individuals who develop the aforementioned disease entities as adults and their time and gender-matched controls. Unparalleled, the study will help determine the effects of vitamin D exposure during critical periods in life. There are a sufficient number of individuals to verify any effects during different gestation phases and seasons of the year. The results, which will change our current understanding of the significance of vitamin D, will enable new research in related fields, including interventional research designed to assess supplementation needs for different subgroups of pregnant women. Also, other health outcomes can subsequently be studied to generate multiple new interdisciplinary health research opportunities involving vitamin D.
To study, prospectively, the association between dietary patterns and risk of health outcomes (cardiovascular, metabolic, endocrine, neurological, skeletal muscular, cancer) in cohort study of 116,671 women age 24 to 44 years at baseline in 1989 (the Nurses' Health Study II; NHS II).
The purpose of this study is to conduct a pilot randomized, controlled trial to evaluate the feasibility and obtain pilot outcome data for a subsequent definitive trial evaluating the effects of postitive airway pressure (PAP) treatment of obstructive sleep-disordered breathing (OSDB) on blood pressure control and maternal and fetal outcomes in hypertensive disorders of pregnancy. The primary aim of the pilot study is to assess feasibility measured as the rates of subject recruitment, adequate (>4h/night) PAP adherence (primary outcome measure) and protocol completion. Secondary aims will be to obtain preliminary data on the effects of PAP on maternal blood pressure, complications of hypertension, arterial stiffness and vascular biomarkers, course of labor and delivery and fetal outcomes including growth restriction, prematurity, and neonatal distress.
A physical activity feasibility randomised control trial for pregnant, obese women.
Women living in low-income countries are at elevated risk of death in connection to pregnancy, as well as infants born to women in such settings. It is probable that several factors are involved, such as poverty, lack of education and access to healthcare. Infectious diseases constitute important threats to maternal health in resource-limited settings. Tuberculosis (TB) is reported to be the third leading cause of maternal death globally. Furthermore, TB can be transmitted from mother to child during pregnancy, with high risk of severe consequences for the infant. Despite these data, neither the role of TB in relation to co-existing risk factors for adverse pregnancy outcomes, nor the mechanisms involved, are well understood. It is likely that TB interacts with other characteristics, in particular socio-economic condition and HIV infection, which could obscure associations between TB and pregnancy outcomes. For this reason, it is critical to design studies so that the independent role of TB can be deduced. This project aims to investigate how TB infection in women affects the risk of adverse pregnancy outcomes in relation to co-existing factors, and how exposure to TB infection may impact growth and development of infants born to women with TB. In addition, mechanisms in which TB and the immune system during pregnancy will be explored. The project is conducted at public health facilities in Ethiopia, where 2 000 women have been recruited during antenatal care. These women will be followed until 5 years after delivery, along with their offspring born during the study period. Detailed data is collected at inclusion and at study visits during follow-up, with submission of samples for TB testing and immunological analyses. Better knowledge on the characteristics of TB infection in association with pregnancy, and how TB affects maternal and child health, can be used to construct new guidelines for management of TB in women of fertile age. This may contribute to reductions in adverse pregnancy outcomes, including maternal and infant deaths.
This study will evaluate the Safety, Pharmacokinetics and Efficacy of IV Administration of Ganaxolone in Women with Postpartum Depression
In this study glucose metabolism of pregnant women with a history of bariatric surgery, obese pregnant women and normal weight pregnant women was investigated. Three to six months after delivery the assessment of Glucose metabolism was repeated and the amount of ectopic lipids in the liver, heart and muscle was measured.
The focus of this work is to improve antenatal care (ANC) and postnatal care (PNC) at the health center level in five districts in Rwanda (Bugesera, Burera, Nyamasheke, Nyarugenge, and Rubavu). 36 health centers in these districts are included in this cluster randomized control trial (RCT) of group ANC and PNC care to measure this alternative model's effects on gestational age at birth, survival of preterm and low birth weight infants at 42 days of life, and ANC and PNC coverage. To improve antenatal assessment of gestational age, nurses will be trained in obstetric ultrasound at 18 health centers. These facilities will also incorporate pregnancy testing with urine dipstick to be performed by community health workers in charge of maternal health to facilitate early entry into ANC. This trial will test the hypothesis that women who participate in this alternative model of group ANC will experience increased gestational age at birth, as compared to women who receive standard focused ANC. This study is a collaboration with the University of Rwanda, the Rwandan Ministry of Health (MOH), the Rwanda Biomedical Center, and UCSF. The group care model used in this study is Rwanda-specific model developed by a Rwandan technical working group. The model includes an individual clinical visit for the first antenatal visit, followed by three group visits spaced about 8 weeks apart throughout pregnancy and a postnatal group visit at approximately 6 weeks after birth. Women will be grouped into stable groups of approximately 8-12 women with similar due dates. A community health worker (CHW) and a health center nurse will work together as co-facilitators to lead each of the groups. Each group visit includes clinical assessment, education, and treatments as appropriate for the women who attend. The model is founded on facilitative leadership of the groups, in which the co-facilitators allow women's experiences and interests to drive the content and women are encouraged to help one another cope with obstacles to optimal health. Facilitators will be supported by master trainers who will visit health centers to observe group sessions and offer supportive feedback. Data collected in this trial will include measures of the satisfaction of both women and providers with the group care, content of care differences between standard and group care, and perinatal outcomes such as gestational age at delivery and 42-day preterm and low birth weight infant survival.
"¡Que Vivan las Madres!: Venga a tener su parto al CAP" (QVLM) is a guatemalan quasi-experimental study that has been performed from January 2014 to January 2017 by the Epidemiological Research Center in Sexual and Reproductive Health (CIESAR) in Guatemala in coordination with PRONTO International and University of San Francisco, California. This project has been financed by Grands Challenges Canada' "Save Lives at Birth, A Grand Challenge for Development" partnership that includes USAID, Norwegian ministry of foreign affairs, Bill&Melinda Gates foundation, UKaid. This project has applied a stepped wedge design (SWD) over 6 zones or clusters. Each one of the zones contains from 4 to 6 communities, each one with the presence of one second level health facility (known in Spanish as CAP, Centro de Atención Permanente). These health centers are the next level in attention after home, traditional and empirical attention. Communities around the selected health centers are mostly rural and have the worst maternal health indicators in the country. These health centers are expected to have enough equipment and personnel to attend the deliveries that occur in their communities. This study was performed in Huehuetenango and Alta Verapaz districts in north Guatemala. Each one with 3 zones for a total of 6 zones. The study follows a Stepped Wedge Design, in which all 6 zones are eventually intervened, but at different regular periods of time (each period is 4 months long). This project applies a package of 3 simultaneous interventions in each zone with the purpose of increasing institutional deliveries and improving deliveries attention in public health centers. This intervention plan has been implemented in a pilot study reported in (Kestler et. al, 2013).
The purpose of this study is to determine whether a combination of evidence-based strategies can improve intrapartum and newborn care in facilities to reduce mortality among preterm infants. This will be a cluster randomized implementation science study across 23 facilities in Eastern Uganda and Western Kenya. Selected interventions will be supported in facilities to measure impact during the study period. These interventions are: a) data strengthening and data use activities; b) implementation of a modified WHO Safe Childbirth Checklist with an emphasis on preterm labor and preterm babies; c) simulation-based provider training and mentoring on key existing evidence-based practices to improve newborn outcomes; d) support of Quality Improvement (QI) cycles to identify and resolve facility-specific issues and bottlenecks. A two-stage design will be used where all study facilities will receive some aspects of the intervention initially, namely data strengthening and the modified checklist. Subsequently, the remaining interventions (QI cycles and simulation training of providers) will be rolled out to a randomly selected half of the facilities in the first stage. At a second stage, the remaining half of the facilities will receive the remaining interventions.
