Reasons and prevention strategies of unintended pregnancy in Addis Ababa, Ethiopia: a phenomenological qualitative study.

OBJECTIVES: To explore the reasons for unintended pregnancy and effective prevention measures from the perspectives of women and healthcare providers in Addis Ababa, Ethiopia. DESIGN: Phenomenological qualitative study. SETTING AND PARTICIPANTS: This study was conducted at three public health facilities found in Addis Ababa, Ethiopia. Women with unintended pregnancies and healthcare providers currently working in maternal health services were purposively recruited for in-depth interviews. Twenty in-depth interviews were conducted until data saturation was achieved. Data were analysed using thematic analysis. RESULTS: Seven themes emerged from the transcribed interview data. These include: Personal characteristics (negligence; lower pregnancy expectation), family influence (fear of family), sociocultural and economic influence (stigma and discrimination), healthcare provider influence (disrespectful and abusive approach; disregard for women's contraceptive choice), preconception thoughts and behaviours (unprotected early sexual practice; myths and misunderstanding), lack of access to quality family planning services (lack of trained contraceptive counsellor, inappropriate contraceptive use), and preventive strategies for unintended pregnancy (comprehensive sexual education; sexual and reproductive health and rights service integration) CONCLUSIONS: This study identified multilevel reasons for unintended pregnancy from the perspective of the participants. Participants shared their views on preventive measures for unintended pregnancy, including comprehensive sexual education, service integration and male-inclusive contraceptive counselling. This study highlights the need to improve sexual and reproductive health services by shedding light on the viewpoints and experiences of women and healthcare providers.

Association between unintended pregnancy and maternal antenatal care services use in Ethiopia: analysis of Ethiopian demographic and health survey 2016.

Introduction: Unintended pregnancy disproportionately affects women in low and middle-income countries including Ethiopia. Previous studies identified the magnitude and negative health outcomes of unintended pregnancy. However, studies that examined the relationship between antenatal care (ANC) utilization and unintended pregnancy are scarce. Objective: This study aimed to examine the relationship between unintended pregnancy and ANC utilization in Ethiopia. Methods: This is a cross-sectional study conducted using the fourth and most recent Ethiopian Demographic Health Survey (EDHS) data. The study comprised a weighted sample of 7,271 women with last alive birth and responded to questions on unintended pregnancy and ANC use. The association between unintended pregnancy and ANC uptake was determined using multilevel logistic regression models adjusted for possible confounders. Finally p < 5% was considered significant. Results: Unintended pregnancy accounted for nearly a quarter of all pregnancies (26.5%). After adjusting for confounders, a 33% (AOR: 0.67; 95% CI, 0.57-0.79) lower odds of at least one ANC uptake and a 17% (AOR: 0.83; 95% CI, 0.70-0.99) lower odds of early ANC booking were found among women who had unintended pregnancy compared to women with intended pregnancy. However, this study founds no association (AOR: 0.88; 95% CI, 0.74, 1.04) between unintended pregnancy and four or more ANC visits. Conclusion: Our study found that having unintended pregnancy was associated with a 17 and 33% reduction in early initiation and use of ANC services, respectively. Policies and programs designed to intervene against barriers to early initiation and use of ANC should consider unintended pregnancy.

Lactobacillus crispatus thrives in pregnancy hormonal milieu in a Nigerian patient cohort.

Steroid hormones are one of the presumed modulators of Lactobacillus abundance in the vaginal epithelium. We set out to characterize the vaginal microbiome (VMB) and also provide an in-depth understanding of the relative contribution of estradiol (E2) and progesterone (P1) in shaping the vaginal microbiome of Nigerian women (n = 38) who experienced both uncomplicated term delivery and preterm delivery using samples longitudinally collected during pregnancy (17-21, 27-31, 36-41 weeks gestation) and 6 weeks postpartum. Vaginal swabs and blood samples were aseptically collected. Vaginal swabs were used for microbiome assessment using 16S ribosomal RNA (rRNA) gene sequencing. Blood samples were used for hormonal measurement using a competitive-based enzyme-linked immunosorbent assay (ELISA). Across several maternal covariates, maternal age, pregnancy status and delivery mode were not significantly associated with the vaginal microbiota whereas maternal E2 level (pE2 = 0.006, Omnibus), and P1 level (pP1 = 0.001, Omnibus) were significantly associated with the vaginal microbiome. E2 and P1 concentrations increased throughout pregnancy commensurately with increasing proportions of L. crispatus (pE2 = 0.036, pP1 = 0.034, Linear Mixed Model). An increasing trend of α-diversity was also observed as pregnancy progressed (pobserved ASV = 0.006, LMM). A compositional microbiome shift from Lactobacillus profile to non-Lactobacillus profile was observed in most postnatal women (pCST IV < 0.001, LMM). Analysis of our data shows a species-specific link between pregnancy steroid hormone concentration and L. crispatus abundance.

Predominance of Atopobium vaginae at Midtrimester: a Potential Indicator of Preterm Birth Risk in a Nigerian Cohort.

Preterm birth (PTB) is the largest contributor to infant death in sub-Saharan Africa and globally. With a global estimate of 773,600, Nigeria has the third highest rate of PTB worldwide. There have been a number of microbiome profiling studies to identify vaginal microbiomes suggestive of preterm and healthy birth outcome. However, studies on the pregnancy vaginal microbiome in Africa are sparse with none performed in Nigeria. Moreover, few studies have considered the concurrent impact of steroid hormones and the vaginal microbiome on pregnancy outcome. We assessed two key determinants of pregnancy progression to gain a deeper understanding of the interactions between vaginal microbiome composition, steroid hormone concentrations, and pregnancy outcome. Vaginal swabs and blood samples were prospectively collected from healthy midtrimester pregnant women. Vaginal microbiome compositions were assessed by analysis of the V3-V5 region of 16S rRNA genes, and potential functional metabolic traits of identified vaginal microbiomes were imputed by PICRUSt (phylogenetic investigation of communities by reconstruction of unobserved states) analysis, while plasma estradiol (E2) and progesterone (P1) levels were quantified by the competitive enzyme-linked immunosorbent assay (ELISA). PTB vaginal samples were characterized by increased microbial richness, high diversity, and depletion of lactobacilli compared to term delivery samples. Women who delivered preterm were characterized by an Atopobium vaginae-dominated vagitype. High relative abundance of Atopobium vaginae at the midtrimester was highly predictive of PTB (area under the receiving operator characteristics [AUROC] of 0.983). There was a marked overlap in the range of plasma E2 and P1 values between term and PTB groups.IMPORTANCE Giving birth too soon accounts for half of all newborn deaths worldwide. Clinical symptoms alone are not sufficient to identify women at risk of giving birth too early, as such a pragmatic approach to reducing the incidence of preterm birth entails developing early strategies for intervention before it materializes. In view of the role played by the vaginal microbiome and maternal steroid hormones in determining obstetric outcome, we assessed the vaginal microbiome composition and steroid hormone during pregnancy and examined their relationship in predicting preterm birth risk in Nigerian women. This study highlights a potential early-driver microbial marker for prediction of preterm birth risk and supports the notion that vaginal microbiome composition varies across populations. A knowledge of relevant preterm birth microbial markers specific to populations would enhance the development of personalized therapeutic interventions toward restoring a microbiome that optimizes reproductive health fitness, therefore reducing the incidence of preterm birth.

The vaginal microbiome of sub-Saharan African women: revealing important gaps in the era of next-generation sequencing.

Accurate characterization of the vaginal microbiome remains a fundamental goal of the Human Microbiome project (HMP). For over a decade, this goal has been made possible deploying high-throughput next generation sequencing technologies (NGS), which indeed has revolutionized medical research and enabled large-scale genomic studies. The 16S rRNA marker-gene survey is the most commonly explored approach for vaginal microbial community studies. With this approach, prior studies have elucidated substantial variations in the vaginal microbiome of women from different ethnicities. This review provides a comprehensive account of studies that have deployed this approach to describe the vaginal microbiota of African women in health and disease. On the basis of published data, the few studies reported from the African population are mainly in non-pregnant post pubertal women and calls for more detailed studies in pregnant and postnatal cohorts. We provide insight on the use of more sophisticated cutting-edge technologies in characterizing the vaginal microbiome. These technologies offer high-resolution detection of vaginal microbiome variations and community functional capabilities, which can shed light into several discrepancies observed in the vaginal microbiota of African women in an African population versus women of African descent in the diaspora.

Predictors of postpartum glucose intolerance in women with gestational diabetes mellitus: a prospective cohort study in Ethiopia based on the updated diagnostic criteria.

OBJECTIVES: To identify the incidence of postpartum glucose intolerance and develop a prediction model based on antenatal characteristics to predict postpartum glucose intolerance. DESIGN: Prospective cohort study. SETTING: Gondar town public health facilities in Northwest Ethiopia. PARTICIPANTS: Women who had gestational diabetes mellitus were advised to undergo postpartum oral glucose tolerance test at 6-12 weeks of delivery. MAIN OUTCOME: Postpartum glucose intolerance. DATA ANALYSIS: Predictors of postpartum glucose intolerance were identified using multivariable logistic regression analysis. The discriminative power of the predictor variables for postpartum glucose intolerance and the model accuracy were computed by area under the receiver operating characteristic curve and estimated by area under the curve (AUC) with 95% CI. RESULTS: A total of 112 (85.5%) women with gestational diabetes mellitus returned and completed the postpartum oral glucose tolerance test. The incidence of postpartum glucose intolerance was 21.4% (95% CI14.3 to 28.4), inclusive of 18.7% pre-diabetes and 2.7% diabetes. Multivariable logistic regression analysis revealed that advanced maternal age, high fasting plasma glucose level at diagnosis, overweight and/or obesity, and antenatal depression were predictors of postpartum glucose intolerance. The AUC of the final reduced model to predict postpartum glucose intolerance was 0.884 (95% CI 0.822 to 0.937). Fasting plasma glucose at diagnosis of gestational diabetes mellitus (AUC=0.736, 95% CI0.616 to 0.845) and overweight and/or obesity (AUC=0.718, 95% CI 0.614 to 0.814) were better predictors of postpartum glucose intolerance. Moreover, the AUC for the combined predictors of fasting plasma glucose at diagnosis and mid-upper arm circumference was 0.822 (95% CI 0.722 to 0.907), which was the best predictor. CONCLUSIONS: The incidence of postpartum glucose intolerance was high among women with gestational diabetes mellitus. Antenatal predictors modestly predicted postpartum glucose intolerance. The findings suggest ongoing glucose screening is indicated for all women with gestational diabetes mellitus.

Gestational diabetes mellitus increased the risk of adverse neonatal outcomes: A prospective cohort study in Northwest Ethiopia.

BACKGROUND: Gestational diabetes mellitus is a rising global public health problem that can have short- and long-term sequelae for both mother and offspring. However, there are limited evidences on the effect of gestational diabetes mellitus on adverse neonatal outcomes using the updated international diagnostic criteria on adverse effects on neonatal outcomes. Therefore, this study was aimed to examine the effects of gestational diabetes mellitus on the risk of adverse neonatal outcomes in Ethiopia. METHODS: A prospective cohort study was conducted among pregnant women recruited from antenatal clinics and followed through pregnancy to delivery. Gestational diabetes mellitus was diagnosed using a two-hour 75g oral glucose tolerance test strategy with recent criteria. Multivariable log-binomial model was used to identify the effects of gestational diabetes mellitus on the risk of adverse neonatal outcomes which includes macrosomia, low birth weight, large for gestational age, small for gestational age, preterm birth, low Apgar score at the first minute, low Apgar score at fifth minute, and composite adverse neonatal outcome. RESULTS: Among pregnant women (n=1027) included in the follow up data on neonatal outcomes were available for 684 (118 newborns of mothers with gestational diabetes mellitus and 566 newborns of women without gestational diabetes mellitus). There was a statistical baseline difference between the two groups by maternal age, dietary diversity status, level of physical activity, and antenatal depression. The incidence of composite adverse neonatal outcome was significantly higher (P<0.001) among newborns from mothers with gestational diabetes mellitus (51.7%) than among newborns from mothers without gestational diabetes mellitus (25.8%). Significantly higher risk of developing adverse neonatal outcomes among newborns from gestational diabetes mellitus mothers was observed for composite adverse neonatal outcome (Adjust Relative Risk (ARR)=1.72; 95% CI: 1.35, 2.19), macrosomia (ARR= 3.81; 95% CI: 1.95, 7.45), large for gestational age (ARR= 2.38; 95% CI: 1.41, 4.03), preterm birth (ARR= 2.03; 95% CI: 1.17, 3.53), low Apgar score at the first minute (ARR= 1.71; 95% CI: 1.02, 2.86), and fifth minute (ARR= 2.14; 95% CI: 1.05, 4.36). However, no significant differences in the risk of low birth weight and small for gestational age by gestational diabetes mellitus status. CONCLUSIONS: Gestational diabetes mellitus increases the risk of adverse neonatal outcomes particularly macrosomia, large for gestational age, preterm birth, and poor Apgar score. Hence, the role of preventing gestational diabetes mellitus is quite crucial to improve neonatal outcomes.

Protocol for a Longitudinal Analysis of the Vaginal Microbiome from a Pregnant Cohort of African Women in Nigeria.

BACKGROUND: The vaginal microbiota is an important component of the reproductive health of women as it offers protection against urogenital infection. African women are reported to have a vaginal microbiota colonized with high proportions of strict anaerobes rather than lactobacillus- dominated microbes. These strict anaerobes have been associated with pre-term birth and neonatal disease. The prevalence of pre-term birth (PTB) in Africa poses a major challenge to reproductive healthcare, hence the clinical and scientific attention focused on understanding the causative mechanisms of PTB. A pragmatic approach to curbing PTB requires the identification of the vaginal microbiome during various stages of a healthy pregnancy (the 'normal'). This information will provide baseline data for future investigations of vaginal microbiome that may cause PTB (the 'abnormal'). We present a protocol for the longitudinal analysis of vaginal microbiome in a cohort of pregnant women in Southwest Nigeria. METHODS: We propose to recruit 51 pregnant Nigerian women, enrolling them into the study at 17-21 gestational weeks. Two vaginal swab samples and three milliliters of blood would be collected at enrollment. Sample collection will be repeated at 27-31 weeks' gestation, ≥36 weeks' gestation, 24-48 hours after birth and 6 weeks post-partum. DNA will be extracted from the vaginal samples and 16S rRNA sequencing would be performed. Blood samples collected would be assayed by ELISA technique for placental steroid hormones. Data will be statistically analyzed and considered in the light of vaginal microbial diversity, clinical, nutrition and other health data. CONCLUSION AND GLOBAL HEALTH IMPLICATION: Our data set will bring new insights into the vaginal microbiome of apparently healthy African women in pregnancy and postpartum, which should serve as a baseline for the investigation of vaginal microbes that may provide useful information for the prediction and management of preterm birth. It is anticipated that these data will facilitate future personalized therapeutic management and consequently improve the reproductive health fitness of women in Africa.

Effects of gestational diabetes mellitus on risk of adverse maternal outcomes: a prospective cohort study in Northwest Ethiopia.

BACKGROUND: Gestational diabetes mellitus is a leading medical condition woman encounter during pregnancy with serious short- and long-term consequences for maternal morbidity. However, limited evidence was available on potential impacts of gestational diabetes mellitus using updated international diagnostic criteria on adverse maternal outcomes. Therefore, this study aimed to assess the effects of gestational diabetes mellitus on the risk of adverse maternal outcomes in Northwest Ethiopia. METHODS: A prospective cohort study was conducted among pregnant women followed from pregnancy to delivery. Gestational diabetes mellitus status was determined by using a two-hour 75 g oral glucose tolerance test and based on updated international diagnostic criteria. Multivariable log-binomial model was used to examine the effects of gestational diabetes mellitus on the risk of adverse maternal outcomes. RESULTS: A total of 694 women completed the follow-up and included in the analysis. Women with gestational diabetes mellitus had a higher risk of composite adverse maternal outcome (ARR=1.58, 95% CI: 1.22, 2.04), caesarean delivery (ARR=1.67; 95%: 1.15, 2.44), pregnancy induced hypertension (ARR= 3.32; 95%: 1.55, 7.11), premature rupture of membranes (ARR= 1.83; 95%: 1.02, 3.27), antepartum hemorrhage (ARR= 2.10; 95%: 1.11, 3.98) and postpartum hemorrhage (ARR= 4.85; 95%:2.28, 10.30) compared to women without gestational diabetes mellitus. CONCLUSIONS: Gestational diabetes mellitus increased the risk of adverse maternal outcomes. This implies that maternal care and intervention strategies relating to women with gestational diabetes mellitus should be strengthened.

Prevalence of gestational diabetes mellitus and associated factors among women attending antenatal care at Gondar town public health facilities, Northwest Ethiopia.

BACKGROUND: Globally, Gestational Diabetes Mellitus (GDM) is rising, but it is a neglected health threat to mothers and their children in low resource countries. Although, GDM is known in Ethiopia, information regarding it remains scarce by recent diagnostic criteria. Therefore, this study aimed to determine the prevalence of GDM and associated factors among women attending antenatal care at Gondar town public health facilities, Northwest Ethiopia. METHODS: A cross-sectional study was conducted among 1027 pregnant women selected by the systematic random sampling technique. The universal one-step screening and diagnostic strategy was done using a two-hour 75 g oral glucose tolerance test. GDM was diagnosed using updated diagnostic criteria (2017 American Diabetes Association (ADA) or 2013 World Health Organization (WHO) or modified International Association of the Diabetes and Pregnancy Study Groups diagnostic criteria (IADPSG)). Binary logistic regression model was used to identify factors associated with GDM. RESULTS: Of the total 1027 pregnant women, 12.8% (95% CI: 10.8-14.8) were diagnosed with GDM. Overweight and/or obesity (MUAC ≥28 cm) (AOR = 2.25, 95% CI: 1.18-4.26), previous history of GDM (AOR = 5.82, 95% CI: 2.57-13.18), family history of diabetes (AOR = 4.03, 95% CI: 1.57-10.35), low physical activity (AOR = 3.36, 95% CI: 1.60-7.04), inadequate dietary diversity (AOR = 1.9, 95% CI: 1.02-3.53), and antenatal depression (AOR = 4.12, 95% CI: 1.85-9.20) were significantly associated with GDM. CONCLUSIONS: The prevalence of GDM among women attending antenatal care at Gondar town public health facilities was high. Previous history of GDM, antenatal depression, family history of diabetes, low physical activity, overweight and/or obesity and inadequate dietary diversity were significantly associated with GDM. Routine screening of pregnant women and healthy lifestyle are strongly recommended.

Prevalence and determinants of gestational diabetes mellitus in Africa based on the updated international diagnostic criteria: a systematic review and meta-analysis.

BACKGROUND: Gestational diabetes mellitus (GDM) is a major public health problem and threat to maternal and child health in Africa. No prior review has been conducted in Africa using the updated GDM diagnostic criteria. Therefore, this review aimed to estimate the pooled prevalence and determinants of GDM in Africa by using current international diagnostic criteria. METHODS: A systematic review and meta-analysis was conducted by comprehensive search of the published studies in Africa. Electronic databases (PubMed, Scopus, Cochrane Library, EMBASE, Google Scholar, CINAHL, Web of Science, Science direct and African Journals Online) were searched using relevant search terms. Data were extracted on an excel sheet and Stata/ SE 14.0 software was used to perform the meta-analysis. Heterogeneity of included studies were assessed using I 2 and Q test statistics. I2 > 50% and Q test with its respective p-value < 0.05 were suggestive for the presence of a significant heterogeneity. Publication bias was assessed using the Egger's regression test and funnel plot. Subgroup and sensitivity analyses were done. A random effects model was used to estimate the pooled prevalence of GDM and odds ratio (OR) with 95% confidence interval (CI). RESULT: A total of 23 studies were included in the final analysis. The pooled prevalence of GDM in Africa was 13.61% (95% CI: 10.99, 16.23; I2 = 96.1%), and 14.28% (95% CI, 11.39, 17.16; I2 = 96.4%) in the sub-Saharan African region. The prevalence was highest in Central Africa 20.4% (95% CI, 1.55, 38.54), and lowest in Northern Africa 7.57% (95% CI, 5.89, 9.25) sub- regions. Overweight and obesity, macrosomia, family history of diabetes, history of stillbirth, history of abortion, chronic hypertension and history of previous GDM had positively associated with GDM. CONCLUSIONS: The prevalence of GDM is high in Africa. Being overweighed and/or obese, ever had macrocosmic baby, family history of diabetes, history of stillbirth, history of abortion or miscarriage, chronic hypertension and history of previous GDM were factors associated with GDM. Preventing overweighed and obese, giving due attention to women having high-risk cases for GDM in pregnancy are strongly recommended to mitigate the burden.

Effect of tranexamic acid on coagulation and fibrinolysis in women with postpartum haemorrhage (WOMAN-ETAC): a single-centre, randomised, double-blind, placebo-controlled trial.

Background: Postpartum haemorrhage (PPH) is a leading cause of maternal death. The WOMAN trial showed that tranexamic acid (TXA) reduces death due to bleeding in women with PPH. We evaluated the effect of TXA on fibrinolysis and coagulation in a sample of WOMAN trial participants. Methods: Adult women with a clinical diagnosis of PPH were randomised to receive 1 g TXA or matching placebo in the WOMAN trial. Participants in the WOMAN trial at University College Hospital (Ibadan, Nigeria) also had venous blood taken just before administration of the first dose of trial treatment and again 30 (±15) min after the first dose (the ETAC study).  We aimed to determine the effects of TXA on fibrinolysis (D-dimer and rotational thromboelastometry maximum clot lysis (ML)) and coagulation (international normalized ratio and clot amplitude at 5 min). We compared outcomes in women receiving TXA and placebo using linear regression, adjusting for baseline measurements. Results: Women (n=167) were randomised to receive TXA (n=83) or matching placebo (n=84). Due to missing data, seven women were excluded from analysis. The mean (SD) D-dimer concentration was 7.1 (7.0) mg/l in TXA-treated women and 9.6 (8.6) mg/l in placebo-treated women (p=0.09). After adjusting for baseline, the D-dimer concentration was 2.16 mg/l lower in TXA-treated women (-2.16, 95% CI -4.31 to 0.00, p=0.05). There was no significant difference in ML between TXA- and placebo-treated women (12.3% (18.4) and 10.7% (12.6), respectively; p=0.52) and no significant difference after adjusting for baseline ML (1.02, 95% CI -3.72 to 5.77, p=0.67).  There were no significant effects of TXA on any other parameters. Conclusion: TXA treatment was associated with reduced D-dimer levels but had no apparent effects on thromboelastometry parameters or coagulation tests. Registration: ISRCTN76912190 (initially registered 10/12/2008, WOMAN-ETAC included on 22/03/2012) and NCT00872469 (initially registered 31/03/2009, WOMAN-ETAC included on 22/03/2012).

Screening for bacterial vaginosis before intrauterine device insertion at a family planning clinic in south-west Nigeria.

AIM: This study determined the prevalence of bacterial vaginosis (BV) among clients before insertion of intrauterine device (IUD) and compared the incidence of complications between participants who were positive and negative for BV. PATIENTS AND METHODS: This was an observational cohort study that was performed between May 2014 and September 2014. A total of 360 women were recruited and followed up for 1 month. High vaginal swabs were obtained from each participant pre-insertion of the IUD and 1 month post-insertion. BV was diagnosed using Nugent's scoring. Data were collected, collated and analysed using frequency distributions and Chi-square test as appropriate. The level of statistical significance was P< 0.05. RESULTS: The prevalence of BV was 33.3%. The complication rate was 23.9% in which 30.5% complication rate was seen among participants positive for BV and 22.5% among participants negative for BV (P = 0.192). This was done with respect to four primary clinical outcomes. The incidence of BV one month after IUD insertion was 11.5%. CONCLUSION: The prevalence of BV was within the range reported in other populations. The complication rate appeared high; however, the differences in proportion between women positive and negative for BV were not statistically significant.

Randomized controlled trial comparing 200µg and 400µg sublingual misoprostol for prevention of primary postpartum hemorrhage.

OBJECTIVE: To compare efficacy and adverse effects of 200µg and 400µg misoprostol for prevention of postpartum hemorrhage (PPH). METHODS: In a randomized control trial, women with term singleton pregnancies in active labor attending University College Hospital, Ibadan, Nigeria, were enrolled between July 2011 and February 2012. Participants were randomly assigned using random numbers (block size four) to receive 200µg or 400µg sublingual misoprostol after delivery of the anterior shoulder, alongside intravenous oxytocin. Investigators were masked to group assignment, but participants were not. The primary outcomes were blood loss up to 1h after delivery, PPH (blood loss ≥500mL), and adverse effects. RESULTS: Overall, 62 patients were assigned to each group. No significant differences between the 200-µg and 400-µg groups were recorded in mean peripartum blood loss (307±145mL vs 296±151mL; P=0.679) and PPH occurrence (5 [8.1%] vs 6 [9.7%] women; P=0.752). Noticeable adverse effects were reported by 16 (25.8%) women in the 200-µg group and 42 (67.7%) in the 400-µg group (P<0.001). Risk of shivering was significantly lower with 200µg than 400µg (relative risk 0.33, 95% confidence interval 0.19-0.58). CONCLUSION: Blood loss and PPH occurrence did not differ by misoprostol dose, but a 200-µg dose was associated with a reduction in adverse effects.

Scourge of intra-partum foetal death in Sub-Saharan Africa.

Intra-partum foetal death has been variously defined. However, a definition adopted at a technical consultation in 2006 is employed in this review. The quality of intra-partum care is a crucial factor for pregnancy outcome for both mothers and new-borns. Intra-partum stillbirth is defined as late foetal death during labour, which clinically presents as fresh stillbirth. The largest proportion of the world's stillbirths occurs in the late preterm, term and intra-partum periods. The Western Pacific region has the greatest reduction in stillbirth with a 3.8% annual decline between 1995 and 2009; however, the annual decline in the African region is less than 1%. Caesarean delivery is still uncommon, especially in rural areas: 1% of births in rural Sub-Saharan Africa and 5% in rural South Asia are by caesarean delivery; 62% of stillbirths occurred during the intra-partum period; 61.4% of stillbirths are attributable to obstetrical complications. Preventive measures aimed at reducing the incidence of intra-partum foetal death entail all measures aimed at improving quality antenatal care and preventing intra-partum asphyxia. This review discusses intra-partum foetal deaths from a Sub-Saharan African perspective. It explores the contribution of research within the region to identifying its impact on new-born health and potential cost-effective policy interventions.

The knowledge base and acceptability of prenatal diagnosis by pregnant women in Ibadan.

This cross-sectional study evaluated knowledge and acceptability of prenatal diagnosis among 500 pregnant women at the University College Hospital, Ibadan. Most participants were aged 25-34 years, self-employed, Muslim, monogamy, secondary school leavers, on income of < naira10,000.00 (US$ 67.00)/month. Attitudinal mean score was dependent on age (p = 0.006), educational attainment (p = 0.001), marital status (p = 0.025) and religion (p = 0.012). Knowledge mean score was influenced by marital status (p = 0.028). Overall, acceptance of prenatal diagnosis was high. There was a direct correlation between acceptance and educational attainment: 41.5%, 31.50%, 19%, 19% of women who agreed to have prenatal diagnosis had tertiary, secondary school, primary school and no formal education respectively. Determinants of acceptability were age, educational attainment, marital status and religion. Being married significantly affected knowledge scores, while tertiary education, being divorced, unskilled and self-employed positively influenced attitude towards prenatal diagnosis.

Correlation between serum immunoglobulin G and hearing threshold among elderly subjects with age-related hearing loss.

BACKGROUND AND PURPOSE: This study was based on the hypothesis that suboptimal immune response and low serum immunoglobulin G (IgG) may predispose to age-related hearing loss (ARHL), and the objective was to determine the serum levels of IgG and hearing thresholds of apparently healthy elderly subjects and assess their correlation. METHOD: This prospective study involved 126 participants ≥ 60 years old who were found to be free of any medical conditions. Pure-tone averages for both the speech (500-2,000 Hz) and high frequencies (3,000-8,000 Hz) and serum IgG levels were determined. Using 30 dB as cut-off for hearing loss, the correlation with serum IgG was assessed. RESULTS: There were 59 males and 67 females with a mean age ± SD of 67.0 ± 2.7 years. Speech frequency hearing loss was seen in 30.2%, while high-frequency hearing loss accounted for 74.6%. In the speech frequencies, the mean ± SD of serum IgG among subjects with normal hearing was 11.3 ± 3.9 g/l, while among those with hearing loss it was 8.3 ± 3.3 g/l (p = 0.01). In the high frequencies, the mean ± SD values of serum IgG among the subjects with normal hearing was 11.1 ± 2.3 g/l, while among those with hearing loss it was 8.7 ± 1.9 g/l (p = 0.01). CONCLUSION: Low serum IgG may be a contributory factor to the development of ARHL among the elderly. However, a longitudinal study involving intervention with immunoglobulin supplementation may further confirm this role.
