Adverse obstetric and neonatal outcomes of adolescent pregnancies in Africa: a scoping review.
Ontology highlight
ABSTRACT: Background
Adolescent pregnancy is a public health issue with well-defined causes and health risks with social and economic implications. Aim of this review was to examine adverse pregnancy outcomes and risk factors associated with adolescent pregnancy in Africa.Method
PubMed Central, Science Direct and JSTOR were the main databases for the literature review. Other online sources and experts were consulted for relevant studies. In all, 11,574 records were identified and 122 were considered as full-text studies for evaluation after thorough screening and removal of duplicates. Finally, 53 studies were included in this review for thematic synthesis.Results
The 53 studies sampled 263,580 pregnant women, including 46,202 adolescents (< 20 years) and 217,378 adults (> 20 years). Adolescent pregnancy was associated with higher risks of adverse pregnancy outcomes. Factors of poor pregnancy outcomes included low socioeconomic and educational status, poor utilization of antenatal care, risky lifestyles such as alcohol consumption, and unattractive health care factors. Maternal health care utilization was identified as an important factor to improve pregnancy outcomes among adolescents in Africa.Conclusion
To prevent adolescent pregnancy, stakeholders need to help lower socioeconomic inequalities, poor utilization of antenatal care, alcohol consumption, and improve adolescents' health care and their educational status. Issues such as child marriage, abortion, poor health care infrastructure and non-adolescent friendly health facilities need to be addressed.

Project description:Background Intrapartum fever is a well-known predisposing factor for severe perinatal outcomes. Herein, we explored the intrapartum features, obstetric outcomes, and neonatal outcomes in relation to the extent of intrapartum fever via three group analyses. Methods A retrospective cohort analysis consisting of 575 term, singleton live births in one medical center from January 1st to December 31st, 2020 was carried out. Parturients who had experienced a maximal intrapartum fever of <38.0 °C were compared with two sub-groups of parturients who had experienced respective maximal fevers of 38.0–38.9 °C and ≥39.0 °C. We computed the adjusted risks for adverse perinatal outcomes via multiple logistic regression models to control for confounders. Results There were statistically remarkable differences among the three groups in 13 items including body mass index, epidural, and WBC before delivery (p < 0.05). In contrast with intrapartum fevers of 37.5–37.9 °C, intrapartum fevers of 38.0–38.9 °C were linked to an elevated risk of neonatal sepsis and neonatal intensive care unit admission with an odds ratio (OR) of 4.28 (95% CI 2.162–8.479) and 1.73 (95% CI 1.125–2.666), nonetheless, the relationship was remarkably higher for intrapartum fever ≥39.0 °C, with an OR of 6.40 (95% CI 2.450–16.725) and 2.23 (95% CI 1.021–4.854). Additionally, intrapartum fevers of 38.0-38.9 °C and ≥39.0 °C were related to remarkably higher risk for operative deliveries (OR 2.24, 95% CI 1.373–3.648; OR 3.59, 95% CI 1.398–9.226; respectively) and histological chorioamnionitis (OR 3.77, 95% CI 2.261-6.271; OR 19.24, 95% CI 7.385–50.111, respectively). Conclusions Intrapartum fever is an important indicator of adverse perinatal outcomes. The higher the temperature, the higher risk of histological chorioamnionitis, as well as the risk of neonatal sepsis and neonatal intensive care unit admission.

Project description:Neuroticism is not only associated with affective disorders but also with certain somatic health problems. However, studies assessing whether neuroticism is associated with adverse obstetric or neonatal outcomes are scarce. This observational study comprises first-time mothers (n = 1969) with singleton pregnancies from several cohorts based in Uppsala, Sweden. To assess neuroticism-related personality, the Swedish universities Scales of Personality was used. Swedish national health registers were used to extract outcomes and confounders. In logistic regression models, odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for the outcomes by an increase of 63 units of neuroticism (equalling the interquartile range). Analyses were adjusted for maternal age, educational level, height, body mass index, year of delivery, smoking during pregnancy, involuntary childlessness, and psychiatric morbidity. Main outcomes were mode of delivery, gestational diabetes mellitus, gestational hypertension, preeclampsia, induction of delivery, prolonged delivery, severe lacerations, placental retention, postpartum haemorrhage, premature birth, infant born small or large for gestational age, and Apgar score. Neuroticism was not independently associated with adverse obstetric or neonatal outcomes besides gestational diabetes. For future studies, models examining sub-components of neuroticism or pregnancy-specific anxiety are encouraged.

Project description:We aimed to describe the characteristics of adolescent pregnancy, determine its effect on adverse maternal and perinatal outcomes and explore whether that association varies with gestational age with the goal of proposing specific recommendations for adolescent health in China. This study included 2,366,559 women aged 10-24 years who had singleton pregnancies between 2012 and 2019 at 438 hospitals. Adolescent pregnancy was defined as younger than 20 years of age. We used multivariable logistic regression to estimate the effects. Women aged 20-24 years served as the reference group in all analyses. The proportion of rural girls with adolescent pregnancies rebounded after 2015 even though common-law marriage in rural areas decreased. Higher risks of eclampsia (adjusted odds ratio (aOR) 1.87, 95% confidence interval (CI) 1.57 ~ 2.23), severe anaemia (aOR 1.18, 95% CI 1.09 ~ 1.28), maternal near miss (MNM; aOR 1.24, 95% CI 1.12 ~ 1.37), and small for gestational age (SGA; aOR 1.30, 95% CI 1.28 ~ 1.33) were observed when gestational age was > 37 weeks. Adolescent pregnancy was independently associated with increased risks of other perinatal outcomes. Further implementation of pregnancy prevention strategies and improved health care interventions are needed to reduce adolescent pregnancies and prevent adverse fertility outcomes among adolescent women in China at a time when adolescent fertility rate is rebounding.

Project description:BackgroundAdolescents have physical, social and psychological characteristics that are different from adults. Adolescent pregnancy results in pregnancy and childbirth complications- an area neglected in developing countries like Ethiopia. This study, therefore, was conducted to assess the adverse neonatal outcomes of adolescent pregnancy in Northwest Ethiopia.MethodsInstitutional-based study was conducted in East Gojjam zone, Northwest Ethiopia. A total of 374 adolescent (15-19 years) and 760 adult (20-34 years) women were included in this study. Data were collected among women who came to randomly selected health facilities in East Gojjam zone. Data were collected by trained research assistants using a structured data collection questionnaire. Descriptive statistics, chi-square test, and Student's t-tests were utilized. Bivariate and multivariable logistic regression analysis were employed to adjust for confounding factors of adverse neonatal outcomes. Statistical significance was declared when the p-value was less than 0.05.ResultsHigher proportion of adolescent than adult women were from rural area (57.2% vs 44.7%), were not married (5.1% vs 1.7%), were pregnant for the first time (91.7% vs 34.1%), didn't attend antenatal care (ANC) follow-up (12% vs 4.5%), and had late initiation of ANC follow-up. After adjusting for known confounding factors, the odds of low birth weight (LBW) was higher among adolescents than adult women (AOR 2.14; 95% CI, 1.36, 3.36, p-value = 0.001). Similarly, the odds of preterm birth was higher among adolescents than adult women (AOR 1.65; 95% CI, 1.09, 2.49, p-value = 0.017). There was no statistically significant difference in the rate of low Apgar score at first and five minutes after birth and neonatal Intensive Care Unit (ICU) admission between babies born from adolescent and adult women.ConclusionsAdolescent women were less likely to receive ANC service. Babies born from adolescent women are at higher odds of adverse neonatal outcomes like LBW and preterm birth than babies born from adult women. Use of community- and health facility-based intervention programs that can prevent adolescent pregnancy and reduce adverse neonatal outcomes among adolescent girls is recommended.

Project description:BackgroundComputational signal preprocessing is a prerequisite for developing data-driven predictive models for clinical decision support. Thus, identifying the best practices that adhere to clinical principles is critical to ensure transparency and reproducibility to drive clinical adoption. It further fosters reproducible, ethical, and reliable conduct of studies. This procedure is also crucial for setting up a software quality management system to ensure regulatory compliance in developing software as a medical device aimed at early preclinical detection of clinical deterioration.ObjectiveThis scoping review focuses on the neonatal intensive care unit setting and summarizes the state-of-the-art computational methods used for preprocessing neonatal clinical physiological signals; these signals are used for the development of machine learning models to predict the risk of adverse outcomes.MethodsFive databases (PubMed, Web of Science, Scopus, IEEE, and ACM Digital Library) were searched using a combination of keywords and MeSH (Medical Subject Headings) terms. A total of 3585 papers from 2013 to January 2023 were identified based on the defined search terms and inclusion criteria. After removing duplicates, 2994 (83.51%) papers were screened by title and abstract, and 81 (0.03%) were selected for full-text review. Of these, 52 (64%) were eligible for inclusion in the detailed analysis.ResultsOf the 52 articles reviewed, 24 (46%) studies focused on diagnostic models, while the remainder (n=28, 54%) focused on prognostic models. The analysis conducted in these studies involved various physiological signals, with electrocardiograms being the most prevalent. Different programming languages were used, with MATLAB and Python being notable. The monitoring and capturing of physiological data used diverse systems, impacting data quality and introducing study heterogeneity. Outcomes of interest included sepsis, apnea, bradycardia, mortality, necrotizing enterocolitis, and hypoxic-ischemic encephalopathy, with some studies analyzing combinations of adverse outcomes. We found a partial or complete lack of transparency in reporting the setting and the methods used for signal preprocessing. This includes reporting methods to handle missing data, segment size for considered analysis, and details regarding the modification of the state-of-the-art methods for physiological signal processing to align with the clinical principles for neonates. Only 7 (13%) of the 52 reviewed studies reported all the recommended preprocessing steps, which could have impacts on the downstream analysis.ConclusionsThe review found heterogeneity in the techniques used and inconsistent reporting of parameters and procedures used for preprocessing neonatal physiological signals, which is necessary to confirm adherence to clinical and software quality management system practices, usefulness, and choice of best practices. Enhancing transparency in reporting and standardizing procedures will boost study interpretation and reproducibility and expedite clinical adoption, instilling confidence in the research findings and streamlining the translation of research outcomes into clinical practice, ultimately contributing to the advancement of neonatal care and patient outcomes.

Project description:ImportanceTwin pregnancy is a common occurrence in pregnancies conceived with in vitro fertilization (IVF), but the absolute risk of adverse obstetric outcomes stratified by IVF, twin or singleton pregnancy, and maternal age are unknown.ObjectiveTo estimate the absolute risk of adverse obstetric outcomes at each maternal age among twin pregnancies conceived with IVF.Design, setting, and participantsThis retrospective cohort study included pregnant women with infants born from January 1, 2013, to December 31, 2018, based on the Hospital Quality Monitoring System in China. Data were analyzed from September 1, 2020, to June 30, 2021.ExposuresTwin pregnancy with IVF (IVF-T), singleton pregnancy with IVF (IVF-S), twin pregnancy with non-IVF (nIVF-T), and singleton pregnancy with non-IVF (nIVF-S).Main outcomes and measuresSixteen obstetric outcomes, including 10 maternal complications (gestational hypertension, eclampsia and preeclampsia, gestational diabetes, placenta previa, placental abruption, placenta accreta, preterm birth, dystocia, cesarean delivery, and postpartum hemorrhage) and 6 neonatal complications (fetal growth restriction, low birth weight, very low birth weight, macrosomia, malformation, and stillbirth).ResultsAmong 16 879 728 pregnant women aged 20 to 49 years (mean [SD] age, 29.2 [4.7] years), the twin-pregnancy rates were 32.1% in the IVF group and 1.5% in the non-IVF group (relative risk, 20.8; 95% CI, 20.6-20.9). The most common adverse obstetric outcomes after pregnancy conceived with IVF were cesarean delivery (88.8%), low birth weight (43.8%), preterm birth (39.6%), gestational diabetes (20.5%), gestational hypertension and preeclampsia and eclampsia (17.5%), dystocia (16.8%), and postpartum hemorrhage (11.9%). The absolute risk of most adverse obstetric outcomes in each subgroup presented in 2 dominant patterns: Pattern A indicated the absolute risk ranging from IVF-T to nIVF-T to IVF-S to nIVF-S, and pattern B indicated the absolute risk ranging from IVF-T to IVF-S to nIVF-T to nIVF-S. Both patterns showed an elevated obstetric risk with increasing maternal age in each subgroup.Conclusions and relevanceIn this cohort study, twin pregnancy, IVF, and advanced maternal age were independently associated with adverse obstetric outcomes. Given these findings, promotion of the elective single embryo transfer strategy is needed to reduce multiple pregnancies following IVF technologies. Unnecessary cesarean delivery shouldh be avoided in all pregnant women.

Project description:IntroductionProblematic sleep is a major threat to health and quality of life among adolescents. Hence, to provide directions for research and interventions, there is a need to examine the literature on adolescent sleep health in Africa. However, available studies on adolescent sleep health in Africa have not been properly mapped. Thus, this scoping review aims to investigate the extent and type of available evidence concerning sleep health among adolescents in Africa and to highlight the relationship of adolescent sleep health with adverse mental health outcomes and cardiometabolic risk factors. The review will further highlight areas of agreement and controversies on adolescent sleep health, and identify evidence gaps that require research attention across the continent.Methods and analysisThis scoping review will be conducted using Arksey and O'Malley's six-step procedure. Thus, we have prepared this protocol according to the framework for scoping reviews developed by the Joanna Briggs Institute. To identify eligible studies, we will search MEDLINE, Scopus, PsycINFO, AJOL, JSTOR, HINARI and Google Scholar. The review will include all published articles in English, French, Spanish, Portuguese and Italian languages on adolescent sleep health in Africa from the inception of the databases, while relevant information will be extracted from included studies using an adapted data extraction tool. The results will be presented using tables and charts as appropriate.Ethics and disseminationThe scoping review does not require ethical approval because the publications to be used for the review are publicly available and the study does not involve contact with humans or other animals as research participants. Furthermore, clinical records will not be used for the study. Upon completion, findings from the study will be disseminated through presentations at scientific meetings and publication in a relevant peer-reviewed journal.Scoping review registrationOpen Science Framework (https://osf.io/5sjwq/).

Project description:BackgroundThe provision of care to pregnant persons and neonates must continue through pandemics. To maintain quality of care, while minimizing physical contact during the Severe Acute Respiratory Syndrome-related Coronavirus-2 (SARS-CoV2) pandemic, hospitals and international organizations issued recommendations on maternity and neonatal care delivery and restructuring of clinical and academic services. Early in the pandemic, recommendations relied on expert opinion, and offered a one-size-fits-all set of guidelines. Our aim was to examine these recommendations and provide the rationale and context to guide clinicians, administrators, educators, and researchers, on how to adapt maternity and neonatal services during the pandemic, regardless of jurisdiction.MethodOur initial database search used Medical subject headings and free-text search terms related to coronavirus infections, pregnancy and neonatology, and summarized relevant recommendations from international society guidelines. Subsequent targeted searches to December 30, 2020, included relevant publications in general medical and obstetric journals, and updated society recommendations.ResultsWe identified 846 titles and abstracts, of which 105 English-language publications fulfilled eligibility criteria and were included in our study. A multidisciplinary team representing clinicians from various disciplines, academics, administrators and training program directors critically appraised the literature to collate recommendations by multiple jurisdictions, including a quaternary care Canadian hospital, to provide context and rationale for viable options.InterpretationThere are different schools of thought regarding effective practices in obstetric and neonatal services. Our critical review presents the rationale to effectively modify services, based on the phase of the pandemic, the prevalence of infection in the population, and resource availability.

Project description:BackgroundEmerging evidence suggests that SARS-CoV-2 infection during pregnancy can result in placental damage and poor placental outcomes. However, the mechanisms by which SARS-CoV-2 infection leads to placental damage are not well understood. With a rapid expansion of literature on this topic, it is critical to assess the quality and synthesize the current state of literature. The objective of this scoping review is to highlight underlying mechanisms of SARS-CoV-2 mediated placental pathology in pregnant individuals and identify literature gaps regarding molecular and cellular mechanisms of poor placental outcomes.MethodsThe review was conducted and reported following the recommendations of the PRISMA extension for Scoping Reviews. The study protocol was registered with Open Science Framework (https://osf.io/p563s/). Five databases (MEDLINE, EMBASE, Scopus, CINAHL, PubMed) were searched for studies published between September 2019 until April 2022. Studies assessing placental outcomes with respect to SARS-CoV-2 infection in pregnancy were eligible for inclusion. Outcomes of interest included histopathology, and molecular or cellular analysis. All records were uploaded into Covidence and extracted using the Joanna Briggs Institute method. Studies were assessed for risk of bias using the Newcastle Ottawa scale and a narrative synthesis of results was generated.ResultsTwenty-seven studies reporting on molecular and/or cellular mechanisms of SARS-CoV-2 mediated placental outcomes were included in this review. SARS-CoV-2 infection was associated with perturbations in the ACE2 pathway, inflammatory mediators and immune cell populations and mitochondrial function in placentas.ConclusionsOur findings suggest that changes in the ACE2 pathway, mitochondrial dysfunction, and/or inflammatory processes may lead to placental damage observed in SARS-CoV-2 infection during pregnancy. More research is needed to understand the role of these pathways further, in addition to data collection related to trimester, severity, and strain.

Project description:BackgroundThe occurrence of maternal anaemia is common in South Asian countries which increase the risk of adverse maternal obstetric and birth outcomes. This may adversely affect the achievement of the Sustainable Development Goals' (SDG) targets of reducing maternal and under-five deaths by 2030.ObjectivesTo summarize the evidence on the association of maternal anaemia with adverse birth and maternal obstetric outcomes.MethodsWe adopted the PRISMA consensus statement. PubMed, CINAHL and Web of Science databases were searched on February 20, 2020. A total of 38 studies was included, of which 25 articles were included in the quantitative synthesis and meta-analysis.ResultsMaternal anaemia was associated with a significantly higher risk of low birth weight (OR, 1.90; 95% CI, 1.06-2.60, p < 0.05), preterm birth (OR, 1.96; 95% CI, 1.20-2.41, p < 0.05) and perinatal mortality (OR, 2.90; 1.97-3.78, p < 0.05). Non-significant associations were seen with neonatal mortality (OR, 1.80; 95% CI, 0.90-27.77, p = 0.7), miscarriage (OR, 1.68; 95% CI, 0.48-3.20, p = 0.08), preeclampsia (OR, 2.66; 95% CI, 0.61-11.52, p = 0.6) and caesarean delivery (OR, 1.18; 95% CI, 0.36-2.80, p = 0.07).ConclusionMaternal anaemia increases the risk of low birth weight, preterm birth and perinatal mortality. Improving maternal nutritional status and iron supplementation during pregnancy are important for reducing these adverse outcomes.
