This was a case-control study to determine the risk factors of preterm delivery among Nigerian women seen at Obafemi Awolowo University teaching hospital, Ile-Ife, Nigeria over a period of 9 months. All women delivering preterm were recruited into the study, with two consecutive term deliveries after each preterm delivery serving as controls. Information obtained from the women includes socio-demographic characteristics, past reproductive and present pregnancy history and outcome. Laboratory investigations were conducted as necessary. Bivariate analysis revealed 21 potential risk factors, however, following adjustment by multiple logistic regression only previous preterm delivery (OR 4.68, 2.24-6.31), previous second trimester spontaneous abortion (OR 4.48, 2.32-8.54), heavy and stressful occupation (OR 3.56, 1.05-6.45), premature rupture of fetal membrane (OR 3.46, 1.04-6.45), maternal medical disorders (OR 3.13, 1.56-5.16), body mass index at delivery of less than 23 (OR 3.01, 1.56-5.43), antepartum haemorrhage (OR 2.73, 1.18-6.34), maternal febrile illness (OR 2.84, 1.32-4.52), intrauterine growth retardation (OR 2.14, 0.98-2.34) and multiple pregnancy (OR 1.98, 1.02-2.68) remained as significant factors.
Two hundred and fifty apparently healthy pregnant women attending the Obstetrics and Gynecology Clinic of the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria were screened for a comparison of the prevalence of HIV seropositivity and hepatitis B surface antigenemia (HBs Ag) amongst them. The Karpas AIDS cell test for HIV seropositivity and Bioman Hepatitis test kits were used as described by the manufacturers. HIV seropositive cases were confirmed using the Western blot test. Results revealed that out of the 250 pregnant women screened, 2 (0.8%) and 11 (4.4%) were HIV-1 and HBs Ag seropositive, respectively. However, the same 2 pregnant women now constituting 2 (18.2%) of the 11 HBs Ag positive pregnant women were simultaneously HIV-1 seropositive. Antibody to HIV-2 was not recorded in all HIV seropositive cases. This is the first report on the simultaneous prevalence of HBs Ag and HIV seropositivity among apparently healthy pregnant women in Lagos, Nigeria.
Fourteen pregnant women with sickle cell disease (11 SS and 3 SC) were randomized into two groups to receive routine antenatal supplementation either with ferrous gluconate or with placebo tablets. Their hemoglobin levels and bone marrow iron content were determined prenatally and 6 weeks post partum. The fetal weights and the incidence of pain crisis in both groups were recorded. Using an iron content grading from 0 to 5, no marrow of any subject showed iron depletion. The placebo group showed an aggregate postnatal loss of 4 grades of iron repletion while the iron supplemented group showed an aggregate gain of 2 grades. There were no significant differences between the birth weight or the incidence of pain crises in both groups. We conclude that routine iron supplementation is not justified in pregnant women with sickle cell disease, as it would tend to increase already adequate or excessive iron body stores. We recommend that a clear need for iron should be established before iron supplementation is prescribed to them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
