Can venous ProBNP levels predict placenta accreta?

Aim: Placenta previa (PP) is a potential life-threatening pregnancy complication. Pro-brain natriuretic peptide (ProBNP), creatine kinase (CK), cardiac form of CK (CK-MB) and Troponin I are circulatory biomarkers related to cardiac functions. We aimed to determine whether these biomarkers are related to PP and placenta accreta. Methods: In this case-control study, fifty-four pregnant women who attended our tertiary care center for perinatology with the diagnosis of PP totalis, and of them, 14 patients with placenta accreta were recruited as the study groups. Forty-six uncomplicated control patients who were matched for age, BMI were also included. Maternal venous ProBNP, CK, CK-MB and Troponin I levels were compared between the three groups. Results: Obstetric history characteristics were comparable among groups, generally. CK and CK-MB levels were similar among three groups. Troponin I levels in the previa and accreta groups were significantly higher than the controls. ProBNP levels in the accreta group were significantly higher than other two groups. The multivariate regression model revealed that ProBNP could predict placental adhesion anomalies. Conclusions: Troponin I and ProBNP levels in PP cases were higher than controls and ProBNP could predict placenta accreta.

Anaemia in women of reproductive age in Dar-es-Salaam, Tanzania

Anaemia is among the greatest health problems in reproductive age women in developing countries. To estimate the prevalence of anaemia among non-pregnant parous women, and to investigate the main underlying cause for the anaemia. A sub-urban Maternal and Child Health Clinic (MCH) in Dar es Salaam. Cross-sectional. Consecutive parous non-pregnant women who had brought their children for vaccination and/or had come for family planning to Mbagala MCH clinic were invited to participate in the study. Obstetric and social history was recorded, and their height and weight were checked. Haemoglobin was measured using HemoCue hemoglobinometer. Anaemic women were further investigated to determine the cause of anaemia by haematological and biochemical tests. Five hundred and four parous non-pregnant women were screened, 49% were anaemic (Hb <12 g/dl) and 1.6% severely anaemic (Hb <7 g/dl). Anaemia was not related to socio-demographic and obstetric history characteristics, but decreased significantly with increasing Body Mass Index (BMI) (p=0.042). The prevalence of anaemia was significantly lower in women using hormonal contraceptives, compared to non-users (36% vs 54%) (p=0.04). Eighty-seven percent of the anaemic women were iron deficient and 8.7% had elevated serum C-reactive protein indicating undiagnosed infections. Nutritional deficiencies in women have to be corrected before and between pregnancies and all contacts women have with the health system should be utilised for anaemia control interventions, in addition to long-term community approaches. To improve maternal health calls for a broader agenda and a change of approach in the MCH-clinics.

Relation of cervical length at 22-24 weeks of gestation to demographic characteristics and obstetric history.

Preterm delivery is the main cause of neonatal death and ultrasonographic cervical assessment has been shown to be more accurate than digital examination in recognizing a short cervix. This is a cross-sectional study, involving 1131 women at 22-24 weeks of pregnancy, designed to determine the distribution of cervical length and to examine which variables of demographic characteristics and obstetric history increase the risk of a short cervix (15 mm or less). The distribution of maternal demographic and obstetric history characteristics among patients with cervical length pound 15 mm was analyzed and compared to the findings for the general population. Risk ratios (RR) between subgroups were generated from this comparison. Median cervical length was 37 mm and in 1.5% of cases it was 15 mm or less. The proportion of women with a short cervix (< or =15 mm) was significantly higher among patients with a low body mass index (RR = 3.5) and in those with previous fetal losses between 16-23 weeks (RR = 33.1) or spontaneous preterm deliveries between 24-32 weeks (RR = 14.1). We suggest that transvaginal sonographic measurement of cervical length be performed as part of a routine midtrimester ultrasound evaluation. There are specific variables of demographic characteristics and obstetric history which increase the risk of detecting a short cervix at 22-24 weeks.
