Predictors of Premature Rupture of Membranes among Pregnant Women in Rural Uganda: A Cross-Sectional Study at a Tertiary Teaching Hospital

Predictors and perinatal outcomes of pre-labor rupture of membrane among pregnant women admitted to Hiwot Fana Comprehensive Specialized University Hospital, Eastern Ethiopia: a retrospective study

Background

Pre-labor rupture of membrane (PROM) refers to a membrane rupture that occurs after the 28th week of pregnancy but before the start of labor. If not appropriately managed, it poses a significant risk to the health of the mother and fetus. However, information on the magnitude of PROM, contributing factors, and its perinatal outcomes was limited in Eastern Ethiopia. This study assessed the prevalence, predictors, and perinatal outcomes of PROM among pregnant women admitted to Hiwot Fana Comprehensive Specialized University Hospital (HFCSUH) in Eastern Ethiopia so as to guide specific preventive measures.

Methods

A hospital-based retrospective cross-sectional study was carried out from May 15 to June 14, 2022, and data were gathered by reviewing the chart records of 424 pregnant women who were admitted to maternity and labor wards in the previous two years, from January 1, 2019 to December 31, 2020. Records were chosen using a simple random sampling method. Mother's socio-demographic traits, previous obstetric and gynecologic history, current pregnancy history, habit-related history (khat chewing), ultrasound findings, laboratory investigations, mode of delivery, maternal and perinatal outcomes were extracted from the maternal charts. Bi-variable and multivariable logistic regression analyses were performed to identify predictors of pre-labor membrane rupture. The association between the explanatory and outcome variables was expressed using an adjusted odds ratio with a 95% confidence interval.

Results

The prevalence of pre-labor membrane rupture was 16.27% with 95% CI: (13.05-20.11). Among 69 women who experienced pre-labor rupture of membrane, 50 (72.5%) of them had adverse perinatal outcomes. Of all 69 neonates 17 (24.64%) were delivered with low birth weight and 20 (29%) of them were born preterm. The overall perinatal mortality rate was 10.1% or 101 per 1,000 live births. History of abortion [AOR = 2.61; 95% CI (1.09, 6.24)], urinary tract infection [AOR = 2.59; 95% CI (1.23, 5.42)], antepartum hemorrhage [AOR = 3.35; 95% CI (1.38, 8.13)], and khat chewing (a leafy plant which contains psychoactive chemical) in the current pregnancy [AOR = 2.63; 95% CI (1.49, 4.63)] were all significantly associated with pre-labor rupture of membrane.

Conclusion

In this study, the magnitude of pre-labor membrane rupture was relatively high compared to the global rate. Prenatal risk identification and early detection of complications among mothers with a history of abortion, antepartum hemorrhage, urinary tract infection, and counseling on the effects of khat chewing during pregnancy are crucial to reduce the likelihood of pre-labor membrane rupture and its adverse perinatal outcome.

Determinants of prelabor rupture of membrane among pregnant women attending governmental hospitals in Jimma zone, Oromia region, Ethiopia: A multi-center case-control study

BACKGROUND

Prelabor rupture of membrane defined as the rupture of fetal membranes before the beginning of uterine contractions, is a common complication of pregnancy and the leading cause of preterm birth. In Ethiopia, the prevalence of prelabor rupture of membrane varied significantly between settings due to variations in risk factors. Besides, there was no study conducted using primary data, particularly in the Jimma zone, Ethiopia. Therefore, this study aimed to identify determinants of prelabor rupture of membrane among pregnant women attending governmental hospitals in the Jimma zone, Oromia region, Ethiopia.

METHODS

An institutional-based unmatched case-control study design was conducted from October 15 to December 15, 2021, at four governmental hospitals. A consecutive sampling technique was used to select 316 participants (79 cases and 237 controls). Women with prelabor rupture of the membrane were confirmed by history, sterile vaginal examination, and ultrasound as cases, and their counterparts as controls. An interviewer-administered questionnaire was used to collect data on maternal (obstetric, medical, behavioral) and fetal-related characteristics. The data were entered into Epi Data version 4.6 and analyzed using SPSS version 25. Descriptive statistics, bi-variable, and multivariable logistic regression were computed. The odds ratio with a 95% confidence level was used, and the significance level was declared at a p-value < 0.05.

RESULTS

A total of 316 participants (79 cases and 237 controls) were included in this study. Pregnancy-induced hypertension (AOR = 3.06, 95% CI: 1.41-6.64), history of abortion (AOR = 3.67, 95% CI: 1.56-8.65), urinary tract infections (AOR = 2.61, 95% CI: 1.13-6.06), abnormal vaginal discharge (AOR = 2.65, 95% CI: 1.21-5.79), maternal khat chewing (AOR = 3.40, 95% CI: 1.70-6.80), mid-upper arm circumference less than 23 cm (AOR = 2.80, 95% CI: 1.51-5.19), and fetal presentation (breech) (AOR = 2.63, 95% CI: 1.10-6.28) were determinants of prelabor rupture of membrane among pregnant women.

CONCLUSION

This study revealed that the aforementioned factors were found to be determinants of prelabor rupture of membrane among pregnant women. Therefore, hospitals should give focus to the early screening, diagnosis, and treatment of pregnancy-induced hypertension, urinary tract infection, and abnormal vaginal discharge to reduce the burden of prelabor rupture of membranes.

Incidence of Cerebral Palsy, Risk Factors, and Neuroimaging in Northeast Mexico

BACKGROUND

Cerebral palsy (CP) comprises a group of lifelong motor and postural development disorders that can cause static motor encephalopathy. The etiology of CP is attributed to nonprogressive lesions of the central nervous system during fetal or infant brain development. A diagnosis of CP is based on a combination of clinical and neurological signs, typically identified between 12 and 24 months. A medical history, several available standardized tools, including the Neoneuro assessment, and the Hammersmith infant neurological examination (HINE) can be used to predict risk. Magnetic resonance imaging (MRI) can contribute to the diagnosis of CP. The incidence of CP is 2 to 3 per 1000 live births, and in Western industrialized nations, it is 2.0-2.5 per 1000 live births; to our knowledge, no epidemiological studies have reported the incidence of CP in Mexico.

AIM

To assess the incidence of CP in children aged up to 18 months in northeast Mexico and analyze the risk factors and neuroimaging findings.

METHODS

This was a multicenter, randomized, prospective, cohort, analytical study of newborn children in three community hospitals and an early intervention and CP center in Nuevo Leon, Mexico, from 2017 to 2021. This study included 3861 newborns randomly selected from a population of 75,951 mothers in the immediate puerperium. According to the Neoneuro tool, high-risk children (n = 432) had abnormal neurological results at birth; they were followed and assessed with the Spanish version of the HINE test by a pediatric neurologist and underwent neuroimaging studies. Neonates with normal results were randomly selected to be in the low-risk group (n= 864). These neonates were followed and assessed with the HINE by a neonatologist.

RESULTS

The incidence of CP was 4.4 of 1000 up to 18 months old, which was higher than that reported in developed countries. Perinatal risk factors were predominantly recognized in the etiology of CP, such as brain hemorrhage, and prematurity, in addition to congenital anomalies. The most frequent neuroimaging findings were ventricular dilation/cortical atrophy and intraventricular/subependymal hemorrhage and periventricular leukomalacia on MRI.

CONCLUSIONS

This study is the first on the incidence/prevalence of CP in Mexico, and there are no formal studies in this field in other Latin American countries either. The incidence of CP in northeast Mexico is higher than that reported in developed countries. The follow-up of high-risk young children must be reinforced in the Mexican population, as children with disabilities have high and sequential health-care needs and may usually be lost to follow-up. Neuroimaging of PVL was the more frequent finding by MRI in this population.

Prevalence of Group B Streptococcus maternal colonization, serotype distribution, and antimicrobial resistance in Sub-Saharan Africa: A systematic review and meta-analysis

OBJECTIVE

Group B Streptococcus (GBS)-associated maternal, perinatal, and neonatal mortality and morbidity disproportionately affects Sub-Saharan Africa (SSA). This systematic review and meta-analysis aimed to address the estimated prevalence, antimicrobial susceptibility, and serotype distribution of GBS isolates in SSA.

METHODS

This study was done according to PRISMA guidelines. MEDLINE/PubMed, CINAHL (EBSCO), Embase, SCOPUS, Web of Sciences databases, and Google Scholar were used to retrieve both published and unpublished articles. STATA software version 17 was used for data analysis. Forest plots using the random-effect model were used to present the findings. Heterogeneity was assessed using Cochrane chi-square (I²) statistics, while the Egger intercept was used to assess publication bias.

RESULTS

Fifty-eight studies that fulfilled the eligibility criteria were included for meta-analysis. The pooled prevalence of maternal rectovaginal colonization and vertical transmission of GBS were 16.06, 95% CI [13.94, 18.30] and 43.31%, 95% CI [30.75, 56.32], respectively. The highest pooled proportion of antibiotic resistance to GBS was observed in gentamicin (45.58%, 95% CI [4.12%, 91.23]), followed by erythromycin, (25.11%, 95% CI [16.70, 34.49]). The lowest antibiotic resistance was observed in vancomycin (3.84%, 95% CI [0.48, 9.22]). Our findings indicate that serotypes Ia/Ib/II/ III/and V cover almost 88.6% of serotypes in SSA.

CONCLUSIONS

The estimated high prevalence and resistance to different antibiotic classes observed in GBS isolates from SSA suggests the need for implementation of effective intervention efforts.

Incidence of preterm premature rupture of membranes and its association with inter-pregnancy interval: a prospective cohort study

Preterm premature rupture of membranes is one of the causes of premature birth and perinatal deaths, particularly in developing countries due to poor access and availability of medical resources to manage and sustain the pregnancy to term. Although, several risk factors for preterm premature rupture of membranes were identified, its association with inter-pregnancy interval was understudied. Therefore, we aimed to assess the incidence of preterm premature rupture of membranes and its association with inter-pregnancy interval in urban South Ethiopia. A community-based prospective cohort study was conducted among 2578 pregnant women, and followed until delivery. A generalized linear model for binary outcome was applied for the analysis, using a 95% confidence level and P-value. The incidence of preterm premature rupture of membranes was 2%, 95% CI: 2%, 3%. However, the incidence was varied across the months of inter-pregnancy intervals 4% (< 18 months), 2% (18–23 months) and 1% (24–60 months). The risk of preterm premature rupture of membranes was nearly three times (ARR = 2.59, 95%CI: 1.27, 5.29) higher for women with inter-pregnancy intervals < 18 months than 24–60 months. Inter-pregnancy interval under 18 months increases the risk of preterm premature rupture of membranes, highlighting the need to improve pregnancy spacing in the community.

Preterm Premature Ruptures of Membrane and Factors Associated among Pregnant Women Admitted in Wolkite Comprehensive Specialized Hospital, Gurage Zone, Southern Ethiopia

Introduction

Preterm premature rupture of membrane is the rupture of membrane before 37 weeks of gestational age. It complicates approximately 3 percent of pregnancies and leads to one-third of preterm births. It increases the risk of prematurity and leads to several other perinatal and neonatal complications, including the risk of fetal death. Although the prevalence and associated factors of preterm premature rupture of the membrane were well studied in high-income countries, there is a scarcity of evidence in Ethiopia, particularly in the study area.

Method

A hospital-based cross-sectional study design was conducted from 1st June to 30th June 2021 in Wolkite comprehensive specialized hospital. One hundred ninety nine (199) pregnant women were included as study subjects using a systematic random sampling technique. Data were collected using a structured interviewer-administered questionnaire. It carried out descriptive statistical analysis and statistical tests like the odds ratio. Both bivariate and multivariate logistic regression analyses were conducted. Statistically, significant tests were declared at a level of p value < 0.05.

Result

The magnitude of preterm premature rupture membrane is 6.6%. Having gestational diabetes mellitus (AOR = 5.99 (95% CI: 1.01, 32.97) and previous history of abortion (AOR = 5.31 (95% CI: 1.06, 26.69) were found to be significantly associated with preterm premature rupture of membrane.

Conclusion

Having gestational diabetes mellitus and having a previous history of abortion were significantly associated with preterm premature rupture of membrane.

Prevalence of premature rupture of membrane and its associated factors among pregnant women in Ethiopia: A systematic review and meta-analysis

Background

Premature rupture of the membrane is a serious public health problem, especially in low- and middle-income countries with significant maternal and perinatal morbidity and mortality. Despite its substantial contributions to feto-maternal complications, the burden of premature rupture of the membrane was not systematically analyzed in Ethiopia. Hence, this review aimed to identify the burden of premature rupture of the membrane and associated factors among pregnant women in Ethiopia.

Methods

PubMed/Medline, Scopus, and African journal online databases and Google Scholar were searched for articles published in the English language. Independent review authors selected and screened studies. Appraisal for methodological quality of studies was conducted using the Joanna Briggs Institute assessment checklist. RevMan 5.3 software was used for meta-analysis. The I ² statistical significance and Egger's test were used to assess heterogeneity and publication bias, respectively.

Results

The pooled prevalence of premature rupture of the membrane among pregnant women in Ethiopia was 9.2% (95% confidence interval = 5.0, 16.4). Factors significantly associated with premature rupture of the membrane were no antenatal care visit (odds ratio = 2.87, confidence interval = 1.34, 6.14), history of premature rupture of the membrane (odds ratio = 4.09, 95% confidence interval = 2.82, 5.91), history of abortion (odds ratio = 3.13, confidence interval = 1.63, 6.01), abnormal vaginal discharge (odds ratio = 6.78, confidence interval = 4.11, 11.16), and urinary tract infection (odds ratio = 3.04, confidence interval = 1.21, 7.63).

Conclusion

Nearly one in ten pregnancies in Ethiopia encounters premature rupture of the membrane complications. The finding highlights improving antenatal care utilization, thus preventing or treating urinary and reproductive tract infections, and tailored interventions for pregnant women with a history of premature rupture of the membrane or abortion contribute to reduced premature rupture of the membrane.

Determinants of Premature Rupture of Membranes Among Pregnant Women Admitted to Public Hospitals in Southern Ethiopia, 2020: A Hospital-Based Case-Control Study

BACKGROUND

A gush of amniotic fluid any time before the onset of labor is known as premature rupture of the membranes (PROM). Its consequences vary from maternal and neonatal mortality and morbidity to country-wide economic loss. At the national level in general, and in the study area in particular, little is known about PROM and its determinants. Hence, this study aimed at identifying determinants of PROM among pregnant women admitted to public hospitals in Southern Ethiopia, 2020.

METHODS AND MATERIALS

A hospital-based unmatched case-control study was conducted on 279 pregnant women (93 cases and 186 controls) admitted to public hospitals from October 1 to 30, 2020. Pregnant women admitted to maternity wards of selected hospitals with a painless gush of fluid spilling out from the vaginal canal were considered as cases. Interviewer-administered questionnaires and data abstraction tools were used to collect data. The data were coded and entered into Epi-Data version 3.1 and exported to SPSS version 23 for analysis. The determinants of PROM were identified by applying a multivariable logistic regression analysis at a p-value <0.05.

RESULTS

Term PROM accounted for the majority, 55 (59.2%) of cases. Previous history of abortion (AOR: 4.14, 95% CI: 2.21-9.07), lack of ANC (AOR: 3.51; 95% CI: 1.33-8.27), previous history of PROM (AOR: 4.91; 95% CI: 2.23-9.82), caesarean delivery (AOR: 3.02, 95% CI: 1.24-6,40), using of a maternal waiting room (MWR) (AOR: 0.33, 95% CI: 0.15-0.74), and mid-upper arm Circumference (MAUC) <23cm (AOR: 3.69, 95% CI: 1.58-8.64) were identified as significant determinants of PROM.

CONCLUSION

Health-care providers should work on providing adequate ANC by tracing mothers who have not received it and advising pregnant women to use MWR in the final weeks of their pregnancy. Furthermore, maternal and child health care units must place a strong focus on screening and managing the nutritional status of pregnant women. Furthermore, women with a history of abortion, caesarean section, and PROM need due attention from health care providers to mitigate the occurrence of PROM.

Prevalence of Preterm Premature Rupture of Membrane and Its Associated Factors among Pregnant Women Admitted in Debre Tabor General Hospital, North West Ethiopia: Institutional-Based Cross-Sectional Study

Background

In Ethiopia, preterm premature rupture of membrane is defined as loss of amniotic fluid before the onset of labor in pregnancy >28 weeks of gestation but before 37 weeks. It is a significant cause of perinatal, neonatal, and maternal morbidity and mortality both in high- and low-income countries. Due to different factors associated with the quality of health care given and socioeconomic factors, the effect of preterm premature rupture of membrane is worsen in low-income countries. Little evidence is available about the problem in the study area. Therefore, this study was aimed to determine the prevalence of preterm premature rupture of membrane and its associated factors among pregnant women admitted in Debre Tabor General Hospital.

Methods

Facility-based cross-sectional study was conducted. A total of 424 mothers were included in the study. Systematic random sampling was used to select study participants. A combination of chart review and interview was used to collect the data. Both descriptive and analytical statistics were computed.

Result

The prevalence of preterm premature rupture of membrane was found to be 13.7%. Pregnant women with abnormal vaginal discharge (AOR = 5.30, 95% CI  = 2.07-13.52), urinary tract infection (AOR = 2.62, 95% CI = 1.32-5.19), history of premature rupture of membrane (AOR = 3.31, 95% CI = 1.32-8.27), vaginal bleeding (AOR = 2.58, 95% CI = 1.14-5.82), and mid-upper arm circumference <23 cm (AOR = 6.26, 95% CI = 3.21-12.20) were associated with preterm premature rupture of membrane.

Conclusions

The prevalence of preterm premature rupture of membrane was high. Abnormal vaginal discharge, urinary tract infection, vaginal bleeding, previous premature rupture of membrane, and mid-upper arm circumference <23 cm were associated with preterm premature rupture of membrane. Thus, early screening and treatment of urinary tract infections and abnormal vaginal discharges were recommended to reduce the risk of preterm premature rupture of membrane.
