BACKGROUND: Routine surveillance of congenital anomalies has shown recent increases in ankyloglossia (tongue-tie) in British Columbia, Canada. We examined the temporal trends in ankyloglossia and its surgical treatment (frenotomy).
METHODS: We...
OBJECTIVE: To describe temporal and regional variations in Canada in the use of operative vaginal delivery (OVD) at term for singleton pregnancies by pelvic station between 2004 and 2013.
METHODS: Rates of OVD among term singleton pregnancies in...
OBJECTIVE: To identify the factors underlying the recent increase in maternal mortality ratios (maternal deaths per 100,000 live births) in the United States. METHODS: We carried out a retrospective study with data on maternal deaths and live births...
OBJECTIVE: To examine temporal trends in early-onset compared with late-onset preeclampsia and associated severe maternal morbidity. METHODS: The study included all singleton deliveries in Washington State between 2000 and 2008 (N=670,120)....
Objective: To compare the diagnostic test properties of automated and visually read urine dipstick screening for detection of a random protein:creatinine ratio (PrCr) ≥ 30mg/mmol. Methods: Urine samples were collected prospectively from 160 women...
Objectives: Microbial invasion of the amniotic cavity (MIAC) can affect outcomes following rescue cerclage. We carried out a study to compare the diagnostic performance of the Gram stain and glucose tests for detecting subclinical MIAC. Methods: We...
Current understanding of the increased risk for stillbirth in gestational diabetes mellitus is often based on large cohort studies in which the risk of stillbirth in women with this disease is compared with the risk in women without. However, such...
εγδβ-thalassemia is rare hematological disease caused by either a deletion of the beta-globin gene cluster, or deletion of the upstream β locus control region (LCR). It results in a phenotype of beta-thalassemia trait in adulthood. In the fetal and...
Objective: To examine the effect of younger versus older children in the family (ages <6 vs. 6-11
years) on the mother’s physical activity, and smoking status. Methods: We studied all women
who participated in the Canadian Community Health Survey...
For clinicians, it is important to rely on accurate laboratory results for patient care and optimal use of health care resources. We sought to explore our observations that urine protein:creatinine ratios (PrCr) >=30 mg/mmol are seen not...
We evaluated the frequency of measurable albuminuria (P6.00 mg/L) for albumin:creatinine ratios (ACr) among 160 consecutive women attending high-risk clinics. Of last urine samples before delivery, 76 had measurable albuminuria and 41/76 (53.9%) had...
Objective: To examine international rates of preterm birth and potential associations with stillbirths and neonatal deaths at late preterm and term gestation. Design Ecological study. Setting: Canada, USA and 26 countries in Europe. Population All...
To identify the risk factors for failed instrumental vaginal delivery, and to compare maternal and neonatal morbidity associated with failed individual and sequential instruments used.
A retrospective case-control study.
From January 1995 to June...
