Caries incidence was assessed in pregnant women in 1998, 2003 an 2008 showing the values to be stable. DMF was almost the same in 1998 and 2003, but in 2008 the rate of "F" (filled) element was significantly higher thus confirming growth in motivation for dental treatment after introduction of private dental practices.
The aim of this study was to provide a temporal-spatial reference of adverse pregnancy outcomes (APO) and examine whether endometriosis promotes APO in the same population. Among the 31?068 women who had a pregnancy between 1997 and 2008 in Eastern Townships of Canada, 6749 (21.7%) had APO. These APO increased significantly with maternal age and over time (r(2?)=?0.522, p?=?0.008); and were dominated by preterm birth (9.3%), pregnancy-induced hypertension (8.3%) including gestational hypertension (6.5%), low birth weight (6.3%), gestational diabetes (3.4%), pregnancy loss (2.2%) including spontaneous abortion (1.5%) and stillbirth (0.6%), intrauterine growth restriction (2.1%) and preeclampsia (1.8%). Among the 31?068 pregnancies, 784 (2.5%) had endometriosis and 183 (23.3%) had both endometriosis and APO. Endometriosis has been shown to increase the incidence of fetal loss (OR?=?2.03; 95% CI?=?1.42-2.90, p?
Acute venous thromboembolism (VTE) is a serious and potentially fatal disorder, which often complicates the course of hospitalized patients, but may also affect ambulatory and otherwise healthy people. While the introduction of thromboprophylactic measures is expected to have reduced the occurrence of postoperative VTE, there is an increasing awareness of the importance of medical conditions in determining thromboembolic events. Among the conditions that predispose patients to VTE are increasing age, cancer and its treatment, prolonged immobility, stroke or paralysis, previous VTE, congestive heart failure, acute infection, pregnancy or puerperium, dehydration, hormonal treatment, varicose veins, long air travel, acute inflammatory bowel disease, rheumatologic disease, and nephrotic syndrome. Other factors that have recently been associated with an increased risk of VTE disorders include persistent elevation of D-dimer and atherosclerotic disease. Recognition of the incidence and clinical importance of thrombosis will most likely encourage more widespread use of antithrombotic prophylaxis in medical patients.
Autoimmune Addison's disease (AAD) tends to affect young and middle-aged women. It is not known whether the existence of undiagnosed or diagnosed AAD influences the outcome of pregnancy.
The aim of the study was to compare the number of children and pregnancy outcomes in individuals with AAD and controls.
We conducted a population-based historical cohort study in Sweden.
Through the Swedish National Patient Register and the Total Population Register, we identified 1,188 women with AAD and 11,879 age-matched controls who delivered infants between 1973 and 2006.
We measured parity and pregnancy outcome.
Adjusted odds ratios (ORs) for infants born to mothers with deliveries 3 yr or less before the diagnosis of AAD were 2.40 [95% confidence interval (CI), 1.27-4.53] for preterm birth (=37 wk), 3.50 (95% CI, 1.83-6.67) for low birth weight (
Few Canadian studies have examined the association between adolescent pregnancy and adverse pregnancy outcomes. The objective of this cohort study was to characterize the association between adolescent pregnancy and specific adverse maternal, obstetrical, and neonatal outcomes, as well as maternal health behaviours.
We conducted a retrospective population-based cohort study of all singleton births in Ontario between January 2006 and December 2010, using the Better Outcomes Registry and Network database. Outcomes for pregnant women
In this retrospective cohort of 165,188 singleton pregnancies and 44,674 multiple-fetal pregnancies in Canada from 1984 to 2000, we compared the incidence of maternal complications. Multiple gestation pregnancies were associated with significant increases in cardiac morbidity, haematologic morbidity, amniotic fluid embolus, pre-eclampsia, gestational diabetes, postpartum haemorrhage, prolonged hospital stay, the need for obstetric intervention, hysterectomy and blood transfusion. Multiple gestation pregnancies are associated with an increased risk of morbidity for the mother. This should be taken into consideration in antenatal care of these women.
Oocyte donation has been associated to gestational diabetes, hypertensive disorders, placental abnormalities, preterm delivery and increased rate of caesarean delivery while simultaneously being characterized by high rates of primiparity, advanced maternal age and multiple gestation constituting the individual risk of mode of conception difficult to assess. This study aims to explore obstetrical outcomes among relatively young women with optimal health status conceiving singletons with donated versus autologous oocytes (via IVF and spontaneously).
National retrospective cohort case study involving 76 women conceiving with donated oocytes, 150 nulliparous women without infertility conceiving spontaneously and 63 women conceiving after non-donor IVF. Data on obstetric outcomes were retrieved from the National Birth Medical Register and the medical records of oocyte recipients from the treating University Hospitals of Sweden. Demographic and logistic regression analysis were performed to examine the association of mode of conception and obstetric outcomes.
Women conceiving with donated oocytes (OD) had a higher risk of hypertensive disorders [adjusted Odds Ratio (aOR) 2.84, 95% CI (1.04-7.81)], oligohydramnios [aOR 12.74, 95% CI (1.24-130.49)], postpartum hemorrhage [aOR 7.11, 95% CI (2.02-24.97)] and retained placenta [aOR 6.71, 95% CI (1.58-28.40)] when compared to women who conceived spontaneously, after adjusting for relevant covariates. Similar trends, though not statistically significant, were noted when comparing OD pregnant women to women who had undergone non-donor IVF. Caesarean delivery [aOR 2.95, 95% CI (1.52-5.71); aOR 5.20, 95% CI (2.21-12.22)] and induction of labor [aOR 3.00, 95% CI (1.39-6.44); aOR 2.80, 95% CI (1.10-7.08)] occurred more frequently in the OD group, compared to the group conceiving spontaneously and through IVF respectively. No differences in gestational length were noted between the groups. With regard to the indication of OD treatment, higher intervention was observed in women with diminished ovarian reserve but the risk for hypertensive disorders did not differ after adjustment.
The selection process of recipients for medically indicated oocyte donation treatment in Sweden seems to be effective in excluding women with severe comorbidities. Nevertheless, oocyte recipients-despite being relatively young and of optimal health status- need careful counseling preconceptionally and closer monitoring prenatally for the development of hypertensive disorders.
There has been little attention paid to asthma complicating pregnancy. This study is among the few studies that investigated this issue in a large Canadian population (more than two millions of Canadian pregnant women).
We carried out a historical cohort study using hospital discharge data collected by the Canadian Institute for Health Information for fiscal years 1989/90 to 1995/96.
A total 2,017,553 obstetric deliveries were included in the analysis. Overall prevalence of asthma among these Canadian women were 0.43%, yielding a total of 8672 cases of asthmatic mothers. Maternal asthma was associated with all of the adverse pregnancy outcomes examined (including fetal death, preterm labour, hypertensive disorders of pregnancy, gestational diabetes, antepartum hemorrhage, infection of the amniotic cavity, premature rupture of membrane, cesarean delivery, as well as postpartum hemorrhage), and adjustment for important confounding factors by multiple logistic regression analysis did not change the overall results. These associations were consistently observed in teenage and adult mothers, although the associations in teenage mothers tended to be stronger than in adult mothers.
This study confirms that pregnant women with asthma are at substantially increased risk for many adverse pregnancy outcomes. For this reason, pregnant women with asthma are a particularly high-risk group to which extra attention, including increased efforts at education, monitoring, and optimal asthma management, may be appropriate.
