Obstructed labor and its effect on adverse maternal and fetal outcomes in Ethiopia: A systematic review and meta-analysis

Determinants of obstructed labour and associated outcomes in 54 referral hospitals in Nigeria

OBJECTIVE

To estimate the prevalence of obstructed labour, associated risk factors and outcomes across a network of referral hospitals in Nigeria.

DESIGN

Retrospective observational study.

SETTING

A total of 54 referral-level hospitals across the six geopolitical regions of Nigeria.

POPULATION

Pregnant women who were diagnosed with obstructed labour during childbirth and subsequently underwent an emergency caesarean section between 1 September 2019 and 31 August 2020.

METHODS

Secondary analysis of routine maternity care data sets. Random-effects multivariable logistic regression was used to ascertain the factors associated with obstructed labour.

MAIN OUTCOME MEASURES

Risk factors for obstructed labour and related postpartum complications, including intrapartum stillbirth, maternal death, uterine rupture, postpartum haemorrhage and sepsis.

RESULTS

Obstructed labour was diagnosed in 1186 (1.7%) women. Among these women, 31 (2.6%) cases resulted in maternal death and 199 (16.8%) cases resulted in postpartum complications. Women under 20 years of age (OR 2.03, 95% CI 1.50-2.75), who lacked formal education (OR 1.88, 95% CI 1.55-2.30), were unemployed (OR 1.94, 95% CI 1.57-2.41), were nulliparous (OR 2.11, 95% CI 1.83-2.43), did not receive antenatal care (OR 3.34, 95% CI 2.53-4.41) or received antenatal care in an informal healthcare setting (OR 8.18, 95% CI 4.41-15.14) were more likely to experience obstructed labour. Ineffective referral systems were identified as a major contributor to maternal death.

CONCLUSIONS

Modifiable factors contributing to the prevalence of obstructed labour and associated adverse outcomes in Nigeria can be addressed through targeted policies and clinical interventions.

Incidence and predictors of mortality among neonates admitted with birth asphyxia to neonatal intensive care unit of West Shewa Zone Public Hospitals, Central Ethiopia

BACKGROUND

Birth asphyxia is still one of the primary causes of newborn mortality worldwide. Similarly, the risk of newborn asphyxia in Ethiopia remains unacceptably high. Thus, studies on the incidence and predictors of mortality among newborns admitted with birth asphyxia are crucial to addressing this problem. As a result, the purpose of this study was to assess the incidence and predictors of mortality among neonates admitted with birth asphyxia to the neonatal intensive care units (NICUs) of West Shewa Zone Public Hospitals in Central Ethiopia.

METHODS

An institution-based retrospective cohort study was conducted among 760 asphyxiated neonates admitted to the NICUs of West Shewa Zone Public Hospitals between 30 March 2021 and 30 April 2023. The data were collected using CSEntry and analysed bu using Stata V.17. Bivariate and multivariate Cox proportional hazard regression analyses were carried out, and significant predictors were found using a 95% CI and a p<0.05.

RESULTS

A total of 760 asphyxiated neonates were followed for a total of 6880 neonatal days. At the end of follow-up, 263 (34.6%) of the neonates died (95% CI 31.3% to 38.1%), which resulted in a mortality incidence of 10.6/100 person-days of observation. Chewing khat (adjusted HR, AHR 2.21; 95% CI 1.13 to 4.31), home delivery (AHR 1.45, 95% CI 1.1 to 1.9), lack of antenatal care follow-up (AHR 1.44, 95% CI 1.08 to 1.89), hypothermia (AHR 1.56, 95% CI 1.12 to 2.17), hypoglycaemia (AHR 2.23, 95% CI 1.91 to 2.25) and obstructed labour (AHR 1.4, 95% CI 1.02 to 1.91) were found to be the significant predictors of neonatal mortality among asphyxiated neonates at a p≤0.05.

CONCLUSION AND RECOMMENDATION

The magnitude of neonatal mortality among asphyxiated neonates in the study area was high. Therefore, in order to significantly reduce the risks of birth asphyxia and subsequent newborn death, all interested stakeholders should take these predictors into consideration.

Incidence of Adverse Perinatal Outcomes among Women Exposed to Maternal Near-Misses in Arsi Zone in Ethiopia: Prospective Cohort Study in 2022

Background

Exposure to maternal near-misses has a massive effect on adverse perinatal outcomes. Hence, investigating the effect of maternal near-misses on perinatal outcomes can aid in the reduction of perinatal morbidity and mortality. The study is aimed at assessing the incidence of adverse perinatal outcomes among women exposed to maternal near-misses at Arsi Zone public hospitals in Ethiopia in 2022.

Method

The study included a prospective cohort of 335 women at Arsi Zone public hospitals from December 2021 to June 2022. Women who were admitted for management of pregnancy were followed. The exposed group was women with maternal near-misses screened based on disease-validated criteria. The nonexposed group was made up of women who delivered without complications. Trained data collectors used pretested, structured questionnaires to collect data from women. Pertinent data was also extracted from the clients' logbooks. Data was transferred from EpiData version 3.1 to SPSS version 25 for analysis, logistic regression was computed, and 95% confidence intervals were declared at a p value of 5% significance level.

Result

The incidence of adverse perinatal outcomes was higher in the exposed women than in the nonexposed women (56% versus 16%). Contrasted with the nonexposed, women exposed to maternal near-misses had a higher incidence of stillbirth (22% vs. 0.5%), low birth weight (13% vs. 3%), and preterm birth (12% vs. 2%). After adjusting for confounders, exposed women had a twofold increased risk of adverse perinatal outcomes compared to nonexposed women. Delivery mode, delay in seeking care, transport mode, and delay in receiving treatment were the risk factors for negative pregnancy outcomes.

Conclusion

In exposed women, a higher incidence of adverse perinatal outcomes was linked to aforementioned risk factors. Evidence-based practice intended to decrease delays in providing maternal care services does indeed improve perinatal outcomes.

Reconsidering the developmental origins of adult disease paradigm: The 'metabolic coordination of childbirth' hypothesis

In uncomplicated pregnancies, birthweight is inversely associated with adult non-communicable disease (NCD) risk. One proposed mechanism is maternal malnutrition during pregnancy. Another explanation is that shared genes link birthweight with NCDs. Both hypotheses are supported, but evolutionary perspectives address only the environmental pathway. We propose that genetic and environmental associations of birthweight with NCD risk reflect coordinated regulatory systems between mother and foetus, that evolved to reduce risks of obstructed labour. First, the foetus must tailor its growth to maternal metabolic signals, as it cannot predict the size of the birth canal from its own genome. Second, we predict that maternal alleles that promote placental nutrient supply have been selected to constrain foetal growth and gestation length when fetally expressed. Conversely, maternal alleles that increase birth canal size have been selected to promote foetal growth and gestation when fetally expressed. Evidence supports these hypotheses. These regulatory mechanisms may have undergone powerful selection as hominin neonates evolved larger size and encephalisation, since every mother is at risk of gestating a baby excessively for her pelvis. Our perspective can explain the inverse association of birthweight with NCD risk across most of the birthweight range: any constraint of birthweight, through plastic or genetic mechanisms, may reduce the capacity for homeostasis and increase NCD susceptibility. However, maternal obesity and diabetes can overwhelm this coordination system, challenging vaginal delivery while increasing offspring NCD risk. We argue that selection on viable vaginal delivery played an over-arching role in shaping the association of birthweight with NCD risk.

Prevalence and Patterns of Neonatal Birth Trauma in Ethiopia: Systematic Review and Meta-Analysis

Introduction. Neonatal death is still alarming in low-income countries including Ethiopia, accounts 30 death per 1000 alive births. Birth trauma is the second most common contributing factors for the death. Nevertheless, there is no aggregate evidence on the prevalence and patterns of neonatal birth trauma in Ethiopia. Therefore, this study aimed to assess the pooled prevalence and patterns of neonatal birth trauma in Ethiopia. Methods. Searching databases including PubMed, MEDLINE, Popline, SCOPUS, Web of Science, EMBASE, CINHAL (EBSCO), Google, Google Scholar, and lists of references were used to search literatures in Ethiopia. STATA version 14 was used for analysis, and the odds ratios of the outcome variable were determined using the random-effects model. Heterogeneity among the studies was assessed by computing values for I2 and P-values. Also, sensitivity analysis and funnel plot were done to assess the stability of pooled values to outliers and publication bias. Results. A total of 6 studies with a sample size of 3663 were included in this study. The overall prevalence of neonatal birth trauma was 15% (95% CI: 13-16). Subgaleal hemorrhage (39%), cephalohematoma (27%), and caput succedaneum (24%) were the most common neonatal birth trauma in Ethiopia. Meta-analyses and sensitivity analyses showed the stability of the pooled odds ratios, and the funnel plots did not show publication bias. Conclusion. This systematic review and meta-analysis revealed a high prevalence of neonatal birth trauma in Ethiopia. Moreover, most of the neonatal birth injuries were severe and life-threatening that need medical attention to safe the neonates and its life long complications.

Gynecological Fistulae-Has Anything Changed in the Diagnosis and Treatment over the Last Decade? A Narrative Literature Review

Gynecological fistulae are a rare but severe complication of radiation therapy, pelvic surgery, prolonged labor, cesarean deliveries, or inflammatory bowel diseases. A gynecological fistula is an abnormal pathway formed between the urinary and gynecological tract, most commonly located between the urinary bladder and vagina. Vesico-uterine and vesicovaginal fistulae are an important health issue, common in women of reproductive age in developing countries with limited access to obstetrical care. Various surgical techniques have been described for VVF repair, depending on the location, severity, and cause of the fistula and the surgeon's experience. The purpose of our review was to evaluate the present state of knowledge about the prevalence and treatment of gynecological fistulae. The PubMed scientific database was searched for original articles on the subject of gynecological fistulae that had been published between 2013 and 2023.

One-sixth of women experienced obstructed labor among those delivered at public hospitals in Southern Ethiopia: A multicenter study

Objective

The study aimed to assess the prevalence of obstructed labor and associated factors among women delivered at public hospitals in Southern Ethiopia.

Methods

Institution-based cross-sectional study was employed among 704 systematically selected postnatal women. The data were collected by the structured and pre-tested interviewer-administered questionnaire and analyzed by Statistical Package for Social Science version 20. Multivariable logistic regression with a 95% confidence level was used to determine the associated factors. Statistical significance was declared at p < 0.05.

Result

The prevalence of obstructed labor was 15.8% (95% confidence interval: 13.1-18.5). Age (adjusted odds ratio = 5.23, 95% confidence interval: 2.98-11.12), antenatal care follow-up (adjusted odds ratio = 1.8, 95% confidence interval: 1.10-3.39), duration of labor (adjusted odds ratio = 4.41, 95% confidence interval: 2.56-7.67), and experiencing complications (adjusted odds ratio = 4.21, 95% confidence interval: 2.63-6.98) were significantly associated with obstructed labor.

Conclusion

The study revealed that one-sixth of women experienced obstructed labor. Regional health sectors and non-governmental organizations need to collaborate with healthcare providers in providing improved maternal health services with special emphasis on teenage women with optimum and proper follow-up throughout the pregnancy, by early identifying complications during labor and delivery to manage the problem early.
