Premature ovarian failure (POF) is known to be associated with an increased risk of ocular surface disease (dry eye), likely due to the reduction of both estrogens and androgens seen in this condition. From preliminary data, we suspect that women with Turners syndrome (45, XO), a genetic abnormality that affects sex hormone levels, are also at increased risk of ocular surface disease. Comparing POF and TS women may allow us to distinguish different mechanisms for ocular surface disease, due to the different etiologies of hormonal (estrogen and androgen) alterations posed by POF and TS.
1. The first aim of this proposal is to pilot the feasibility of weekly phone monitoring of infant feeding and illness patterns in a socio-economically and racially diverse population. Specifically, the investigators aim to estimate the rate of group loss to follow up from birth to 13 weeks (3 months) of age with weekly phone interview of mothers of late preterm (LPT, gestational age 34 0/7- 36 6/7 weeks gestation) infants. 2. The second aim is to describe breastfeeding and formula feeding practices, and rates of illness and post-discharge hospital care utilization, through age 13 weeks (3 months) among late preterm infants born at MacDonald Women's Hospital. The investigators estimate that the rate of exclusive breastfeeding among LPT infants at 3 months of age is less than the documented rate of 37% for all infants in Cuyahoga County.
An epidemiologic study of pregnant women in western Washington to measure the relationships between exposure to air pollutants and risks of preeclampsia and preterm delivery.
The purpose of this study is to study the relation between mechanical ventilation and ADMA concentrations at birth.
This is a phase one study investigating the absorption, distribution, metabolism and excretion of GSK221149A in six healthy women of non-child bearing potential.
The purpose of this study is to measure hormones in the blood known to affect the timing of delivery after a single injection of 17-P in order to help understand its mechanism of action in preventing preterm delivery.
Analyze the possible effect of the progesterone levels of the hCG administration on the oocyte embryo quality. The primary endpoint of this study is the pregnancy rate.
Background. Influenza is increasingly recognized as causing severe respiratory illness in children. High-risk infants, like former premature infants, and particularly those with lung disease, have influenza hospitalization rates about five times higher than healthy children. Influenza vaccine does not protect young children against influenza as well as it does healthy adults. A small study that measured antibodies (proteins that protect against infection) to influenza suggested that premature infants get even less protection from influenza vaccine than full-term infants. More information about influenza vaccine in premature infants is needed. The overall goals of this project are to collect information about the how well the influenza vaccine induces antibody production, and to develop the collaborative network of centers necessary for a larger trial of influenza vaccine in premature infants. Objective and Hypotheses. The objective of this study is to measure the amount of protective antibody produced by influenza vaccine in premature (less than 30 weeks' [about 7 months] gestation at birth), extremely-low-birth-weight (1000 grams [2¼ pounds] or less at birth) infants. Influenza vaccine needs to be given yearly. We will assess premature infants during their first series of influenza vaccines. We hypothesize that the levels of antibody will be lower in premature infants receiving their first series of influenza vaccine than in full-term infants. Design. We will measure the immune response in premature and full term infants. During the 2007-2008 influenza season, a total of 92 subjects, divided among 2 groups (premature infants 6-17 months old receiving their first influenza vaccine series and full-term infants 6-17 months old receiving their first influenza vaccine series) will be recruited at a consortium of five centers (the University of Rochester, the University of Texas Southwestern Medical Center, Wake Forest University, the University of Miami and the State University of New York at Buffalo), receive 2 doses of influenza vaccine, and have antibody and immune cell responses to each vaccine component measured 4-6 weeks after the second dose of vaccine. Potential Impact. If this study and future investigations suggested ways to improve premature infants influenza vaccine responses, they could lead to changes in recommendations for the number or timing of vaccine doses or of the type of vaccine used in this high-risk group.
The purpose of this study is to determine if there may be a benefit to the newborn if betamethasone is given 12 hours apart instead of 24 hours apart.
