Filter by:There is a lack of consensus on whether women with proteinuric kidney disease benefit from prophylactic anticoagulation during pregnancy to reduce the risk of venous thromboembolism. This pilot study will investigate the feasibility of obtaining thrombosis profile data using a viscoelastic haemostasis monitor - Sonoclot - from pregnant women with kidney disease, and exploratory analyses to elucidate correlations between output values and clinical parameters
Between fifty and eighty percent of pregnant women experience nausea and vomiting in pregnancy making it one of the most common medical complications of pregnancy. Hyperemesis gravidarum is an extreme form of nausea and vomiting of pregnancy and results in evidence of acute starvation (i.e. large ketonuria), and weight loss (>5% of a woman's pre-pregnancy weight). Hyperemesis gravidarum is also surprisingly common. In fact, it is the second leading cause of preterm hospitalization during pregnancy, second only preterm labor. Hospitalization is often required because hyperemesis is frequently refractory to common anti-nausea medications. However, capsaicin cream, a potent TRPV1 agonist, commonly used to relieve muscular and neuropathic pain, may be able to reduce the symptoms of nausea and emesis in patients with nausea and vomiting of pregnancy. Smaller studies have demonstrated capsaicin to be both safe and effective when used to treat intraoperative nausea during cesarean delivery. To begin to address whether capsaicin cream could be used to reduce preterm admissions and shorten emergency room visits for hyperemesis, this study will randomize women presenting to the emergency room for nausea and vomiting to treatment with capsaicin cream as an adjunctive medication or routine care. The project will investigate the impact of capsaicin cream on hospital length of stay as well as representation for additional treatment. If effective, capsaicin cream has the potential not only to reduce emergency room visits, hospital admissions and overall health care costs, but also to drastically improve patient quality of life.
This pilot and feasibility study will enroll newly pregnant women at risk for high sedentary behavior (SED) and elevated APO risk (n=53) and will randomize them to either a SED reduction intervention or control. Research aims include to: 1) demonstrate our ability to decrease SED and increase standing and light activity in pregnant women; 2) evaluate feasibility; and 3) gather preliminary effects on clinical outcomes including APOs, cardiometabolic risk factors, well-being, and fetal outcomes.
1. Evaluation of the efficacy of aspirin in preventing preeclampsia and its serious complications during pregnancy and postpartum. 2. To establish a risk prediction model for severe pregnancy complications in pregnant women with hypertensive disorders of pregnancy.
Approximately 1 in 500 pregnant women require non-obstetric surgery. Surgical care for the pregnant woman raises concern for complications adversely affecting pregnancy outcomes. The most common reason for surgery is acute appendicitis followed by gallbladder disease. Despite the common incidence of non-obstetric surgery among pregnant women, little is known regarding fetal outcome and the impact of laparoscopic interventions versus traditional open procedures. Even less is known about the role of non-operative management of general surgical disease in the pregnant population. However, fetal outcome is not compromised by emergency general surgery condition interventions.
The aim of the GLORIA study is to determine whether an altered glucose metabolism (with more hypoglycaemia and glycaemic variability) and altered metabolomics during pregnancy after bariatric surgery contribute to the increased risk for adverse pregnancy outcomes such as small-for-gestational age infants. In addition, the investigators also aim to evaluate whether continuous glucose monitoring (CGM) can be used to diagnose gestational diabetes (GDM).
This prospective nested case-control study aims to examine the effects of blood vitamin B levels in first-trimester pregnant women on the pregnancy outcomes
This study is being conducted to investigate how a mother's nutritional status and her gut microbiome during pregnancy contribute to the birth outcomes and health of her baby. The gut microbiome is the totality of microorganisms (e.g. bacteria, viruses, fungi) living in the gastrointestinal tract. This study will focus on pregnant women, 24 years and younger living in the Toronto and greater Toronto area. The focus is on younger women due to their vulnerability to undernutrition. Pregnant participants, and upon delivery, their newborns will be followed throughout pregnancy and for a year afterwards. Throughout this period, the investigators will collect stool samples, rectal swabs, blood samples, health assessments, nutritional and dietary assessments and birth/ labour details. The goal is to define the relationship between a mother's nutritional status and her microbiome dynamics during pregnancy and how they contribute to the birth outcomes and growth of her newborn. With the hypothesis that alterations of the microbiota in the maternal gut (dysbiosis) exacerbated by nutritional status or pathogen exposure during pregnancy, impacts weight gain because of impaired nutrient absorption, leading to corresponding negative birth outcomes.
A total of 1900 pregnant women in the 1st trimester and their children will be enrolled and followed for two years (ORCHID study main cohort). As part of this, mother-infant pairs will be required to attend up to 10 study visits separate from routine clinic visits, these visits include 3 antenatal visits (less than or equal to 18, 24-28 and 32-36 weeks) and 16 postnatal visits (<2 and 6 weeks, 3, 6, 12, 18, and 24 months). Participants will also be asked to engage in long-term follow-up, with visits occurring every 6 months through Month 60 (at 30, 36, 42, 48, 54, and 60 months). Measurements in mothers will include demographics and health status, HIV disease and ART use, intercurrent medical history including concomitant medication use, HIV viral load testing, ART adherence, HIV antibody testing in women without HIV; body composition, caloric intake, dysglycemia and insulin resistance (IR), lipid profiles, anthropometry, resting energy expenditure, hepatic steatosis, specimen collection (whole blood, plasma, serum, urine, placenta and breastmilk), systemic and adipose inflammation, as well as metabolites, lipid subspecies and eicosanoids. Measurements in infants will include uterine gestational age and fetal growth, as well as metabolites, lipid subspecies and eicosanoids, body composition, dysglycemia and IR, lipid profiles, anthropometry, feeding, specimen collection (cord blood, whole blood, plasma and serum) and intercurrent medical history including concomitant medication use. Additional data on maternal health in pregnancy and birth outcomes will be abstracted from medical records.
Pre-eclampsia (PE) remains a major source of maternal and perinatal morbidity and mortality especially in low- and middle-income settings. PE, a pregnancy-specific hypertensive disorder, characterized by the development of placental endothelial dysfunction resulting in, among the most common diagnostic features, concomitant hypertension and proteinuria that may evolve into organs with fluctuating clinical specificities. Current studies indicate that periodontal disorders during pregnancy and particularly periodontal pathogens may be related to the risk of PE. Standard oral hygiene methods, based mainly on the joint use of toothbrushes and interdental brushes, reduce periodontal inflammatory risk, modulate of the dysbiotic oral microbiome. The purpose of the present study is to compare the PE outcomes in high-risk pregnant women receiving oral prophylactic measures to a control group. One specific question is addressed as follows according to the PICO principles: In high-risk pregnant women (Population), does oral prophylactic measures (Intervention) have a beneficial effect on PE parameters (Outcome) compared to pregnant women without any specific oral prophylactic measures (Control)?
