Filter by:Influenza virus accounts for numerous cases (epidemics) of respiratory illnesses each year worldwide and affects people of all ages. These epidemics typically occur in the winter months, and can result in substantial morbidity and mortality in persons at risk. Pregnant women may be more susceptible to morbidity and mortality associated with influenza infection. This increased risk may result from several factors including increased heart rate, stroke volume, and oxygen consumption, decreased lung capacity, and changes in immunologic function. Immunization of women during pregnancy can help to prevent infection in the woman herself and may also offer protection to the infant in two ways: by the passage of antibodies from mother to the fetus during pregnancy, and by preventing infection in the mother and therefore decreasing the infant's exposure risk after birth. In Canada, the National Advisory Committee on Immunization (NACI) recommends the vaccine for pregnant women who are expected to deliver during influenza season because they will become household contacts of their newborn. Ideal timing of vaccination occurs in October or November since influenza outbreaks typically occur throughout the winter months. Despite the Canadian and American guidelines for influenza vaccination during pregnancy, it is unclear how many women are offered and/or actually receive the vaccine while pregnant. There is, however, evidence that women will accept the vaccine if offered. Specifically, in the Women's Health Care Centre at St. Michael's Hospital, it was found that 42% of women not only accepted but also received the influenza vaccination when offered. Innovative techniques will be required to continue to increase vaccination rates among vulnerable populations, including pregnant women. The purpose of the present study is to determine if the use of electronic reminders (text messages) increases the likelihood of receiving the influenza vaccine among pregnant women.
This study assessed the relationship between pregnant women, partner support, and cigarette and alcohol use in pregnancy.
The aim of this study is to examine the effect of a supervised physical exercise program during pregnancy on fetoplacental growth.
The aim of this feasibility study is to test recruitment of participants into Phase 1 of the study and then the re-recruitment and retention of participants in Phase 2 of the study. The investigators will also be assessing the acceptability of recruitment strategy and data collection to participants. The effect of pre-pregnancy factors (biophysical, genetic, socioeconomic, behavioural and psychological) on obstetric, cardiovascular, socioeconomic, behavioural and psychological outcomes will all be examined.
The aim of the present study is to evaluate the impact of hysteroscopy prior to starting the IVF (in vitro fertilisation) cycle on treatment outcome in women with unexplained primary infertility.
To assess the proportion of women who use HERC for ≥2 years of duration
Despite the great health benefits associated with smoking cessation in pregnancy to both mother and baby, few studies to date have examined the applications of text messaging or other communication technologies for smoking cessation in this population. This project is the first step in developing a new dissemination strategy for reaching pregnant smokers. This research will explore how a state-of -the-art, interactive and intensive, text messaging program, SmokefreeMoms Text, can promote smoking cessation in pregnant smokers. This program may have the potential to reach pregnant smokers who are not currently being reached with traditional smoking cessation services. The study Aims are: 1) to elicit qualitative feedback from pregnant smokers and recent quitters (in the past month) about the concept of SmokefreeMoms, the proposed message protocols in SmokefreeMoms, and the proposed messages in SmokefreeMoms (Phase 1); 2) To develop and pilot test a prototype of SmokefreeMoms which is consistent with Clinical Practice Guidelines (Phase 2), and 3) To conduct a formative evaluation of SmokefreeMoms 1.0 with pregnant smokers and recent quitters (Phase 3). 4) To measure the likelihood that pregnant women who smoke cigarettes will join an SMS program by responding to different types of recruitment messages.
The goal of this project is to evaluate the effectiveness (Phase II) of a text-based program to be called Quit4Baby to support smoking cessation efforts of pregnant women who smoke. In Phase II, Dr. Abroms will conduct a randomized clinical trial among 500 pregnant smokers who have been recruited from users of text4baby - the first large scale mobile health application in the United States. Developed and operated by Voxiva and Healthy Mothers, Healthy Babies (HMHB)—collaborators in this program -text4baby is a free national service that has enrolled more than 800,000 pregnant women and mothers of infants 0-1 nationwide and delivered more than 150 million health messages to them including messages encouraging them not to smoke during pregnancy and referring them to quit lines. Hypothesis 1: Pregnant smokers who receive quit4Baby + text4Baby will demonstrate higher levels of knowledge about the dangers of second hand smoke and the benefits of smoking cessation for mothers and their infants than text4baby only users. Hypothesis 2: Pregnant smokers who receive quit4baby + text4baby will report significantly higher rates of calling a quit line, discussions with their health provider and/or use of cessation counseling than those who receive Text4baby alone. Hypothesis 3: Pregnant smokers who receive quit4baby + text4baby will have significantly more favorable quitting outcomes compared with text4baby alone.
This study is testing the hypothesis of whether continuous positive airway pressure (CPAP) therapy improves placental histopathology and secretory function. The main aims of the study are to identify shared mechanisms between obstructive sleep apnea and preeclampsia, both common highly morbid conditions.
To assess which of two commonly utilized insulin drip protocols has better outcomes when used during the labor process.
