A narrative review. Congenit Anom (Kyoto) 2024. [PMID: 38897927 DOI: 10.1111/cga.12576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 04/26/2024] [Accepted: 06/03/2024] [Indexed: 06/21/2024]
Abstract
There is an increase in the worldwide prevalence of congenital abdominal wall defects (CAWD), with gastroschisis (GS) and omphalocele (OC) being the most common. It is widely accepted that folic acid supplementation (FAS) in the maternal diet decreases the incidence of anomalies such as neural tube defects, but there is controversy regarding the possible beneficial role for other congenital malformations. Several epidemiological studies raise controversy regarding a possible relationship between vitamin supplementation with the occurrence of abdominal wall malformations. The aim of the present study is to obtain an updated review of the global frequency of CAWD in neonates and the relationship with FAS in the mothers. For this we have carried out a systematic search of epidemiological studies in different article databases between 2011 and 2022. The analysis of 25 studies conducted in different countries where cases of OC and/or GS are registered directly or together with other congenital defects shows that 60% inquire into the relationship of FAS with the incidence of CAWD. Half of them proposes a beneficial effect of FAS and the other half find no association, concluding that there is no unanimous evidence that FAS in the maternal diet decreases the incidence of CAWD. However, it seems that an influential factor to take into account is the nutritional habits of the mothers.

Abstract
BACKGROUND Congenital anomalies represent a significant contributor to infant mortality, morbidity, and enduring disability. With this in mind, the present investigation endeavour to ascertain the pooled prevalence of congenital anomalies and associated determinants among neonates in Ethiopia. METHOD PubMed, Google Scholar, CINAHAL, Hinari, and Global Health databases were systematically searched. Joanna Briggs Institute (JBI) assessment checklist was used to assess quality of included studies. Data were extracted from database and exported to stataMP-17 for analysis. Pooled prevalence was determined using DerSimonian-Laird random effects model. The degree of heterogeneity and Publication bias were assessed using I2 statistics and Eggers test, respectively. Study protocol was registered under PROSPERO ID CRD42021229140. RESULT A total of 18 studies with 519,327 participants were included in the study. Pooled prevalence of congenital anomalies in Ethiopia was 2% (95% CI: 0.02, 0.03%). Among affected newborns neural tube defect (48%) was the most common congenital anomaly in Ethiopia, followed by orofacial cleft (19%). Risk factors such as alcohol consumption (pooled OR: 2.28, 95% CI: 1.54, 3.38), lack of folic acid supplement (pooled OR: 2.83, 95% CI: 1.09-7.36), medication during pregnancy (pooled OR: 2.58, 95% CI: 1.03-6.47), khat (Catha edulis) chewing (pooled OR: 2.44, 95% CI: 1.61-3.71), exposure to pesticides (pooled OR: 4.45, 95% CI: 2.44-8.09) and maternal illness (pooled OR:1.79, 95% CI: 1.03, 3.10) had statistically significant association with congenital anomalies in Ethiopia. CONCLUSION In this review, prevalence of congenital anomalies in Ethiopia was high with considerable regional variation. The most common type of congenital anomaly in Ethiopia was neural tube defects, followed by oro-facial cleft. Alcohol consumption, inadequate intake of folic acid, khat chewing, maternal diseases, exposure to pesticides, and use of medication during pregnancy were identified as potential contributors to congenital abnormalities in Ethiopia.

Abstract
OBJECTIVE Over 8 million newborns worldwide have congenital anomalies; 3.2 million have resultant disabilities. Ethiopia has a high burden of neonatal congenital anomalies, but research on predictors is limited. This study investigated predictors of neonatal congenital anomalies in eastern Ethiopia. METHODS A facility-based unmatched case-control study on 387 mother-infant pairs (129 cases, 258 controls) in public hospitals was conducted. Data were obtained using an interviewer-administered structured questionnaire and a medical record review. Binary logistic regression with adjusted odds ratios (AOR) and 95% confidence intervals (CI) was used to identify predictors of congenital anomaly. RESULTS Nervous system anomalies were most common 84 (65.1%), followed by gastrointestinal system anomalies 20 (15.5%). Maternal anemia (AOR: 4.37, 95% CI: 2.48-7.69), alcohol consumption during index pregnancy (AOR: 4.01, 95% CI: 1.88-8.54), khat chewing (AOR: 1.73; 95% CI: 1.04-2.85), rural residence (AOR: 1.73, 95% CI: 1.04-2.85) and antenatal care attendance (AOR: 0.43, 95% CI: 0.22-0.84) were significant predictors of congenital anomaly. CONCLUSION Several risk factors for congenital anomalies were identified. To reduce risk, antenatal care services should be improved and mothers encouraged to avoid harmful substances during pregnancy and maintain a healthy lifestyle. Intervention strategies are needed to target these risk factors.

Abstract
Background Diabetes is a chronic metabolic syndrome that is a global public health problem. Studies have used hematological parameters and hemogram-derived markers as predictors of poor glycemic and microvascular complications status in diabetics. However, the tendency to use these parameters is not fully evaluated in our context, and the evidence is inadequate. This study aimed to assess the hematological profiles and prognostic role of hemogram-derived novel markers in diabetes mellitus and its complications among DM patients at Bishoftu General Hospital, Ethiopia. Methods A comparative cross-sectional study was conducted among 261 participants from June 15 to August 12, 2022. A systematic random sampling technique was used to select participants. Data were collected using structured questionnaires, physical measurements, checklists, and laboratory tests. Hematological parameters and fasting blood glucose levels were determined from blood using Sysmex-XN550 and Cobas C311 analyzers, respectively. Blood smear was used to check Hematology analyzer output, and to screen participants for malaria parasites. Collected data were entered into Epi-data 3.1 and exported to SPSS-25. Data were analyzed by Chi-square, Mann-Whitney U-test, Kruskal-Wallis test, Post hoc test, and ROC curve. A P-value <0.05 was considered statistically significant. Results Total WBC, neutrophils, Monocyte, NLR, MLR, MPVLR, and PLR were significantly higher in poor glycemic and complicated T2DM; meanwhile, measured RBC parameters, RBC indices values were significantly lower in poor glycemic and complicated T2DM. The NLR, MLR, MPVLR, PLR, and NLR, MLR, MPVLR, RPR values were identified as predictors of poor glycemic and complication status in diabetic patients, respectively. Conclusion Significant increment of some hematological parameters and hemogram-derived markers, and their role in predicting poor glycemic and microvascular complications were identified in diabetic patients. Routine screening of hematological parameters and use of hemogram-derived markers for monitoring of altered health status in DM is very important in the improvement of patient quality of life.

Abstract
Background Several studies have been conducted on structural congenital anomalies (CA). However, there is a paucity of studies that provide a comprehensive review of structural anomalies. We aimed to verify the available research articles to pool the possible risk factors of structural CA in resource-limited settings. Setting The research articles were genuinely searched using PubMed, Scopus, Cochrane Library, Web of Science, free Google database search engines, Google Scholar, and ScienceDirect databases. Published studies were searched and screened for inclusion in the final analysis, and studies without sound methodologies and review and meta-analysis were not included in the analysis. Participants This review analyzed data from 95,755 women who gave birth as reported by primary studies. Ten articles were included in this systematic review and meta-analysis. The articles that had incomplete information and case reports were excluded from the study. Results The overall pooled effect estimate (EI) of structural CA was 5.50 (4.88-6.12) per 100 births. In this systematic review and meta-analysis, maternal illness EI with odds ratio (OR) = 4.93 (95% CI: 1.02-8.85), unidentified drug use with OR = 2.83 (95% CI: 1.19-4.46), birth weight with OR = 4.20 (95% CI: 2.12-6.28), chewing chat with OR = 3.73 (95% CI: 1.20-6.30), chemical exposure with OR = 4.27 (95% CI: 1.19-8.44), and taking folic acid tablet during pregnancy with OR = 6.01 (95% CI: 2.87-14.89) were statistically significant in this meta-regression. Conclusions The overall pooled effect estimate of structural CA in a resource-limited setting was high compared to that in countries with better resources. Maternal illness, unidentified drug use, birth weight, chewing chat, chemical exposure, and never using folic acid were found to be statistically significant variables in the meta-regression. Preconception care and adequate intake of folic acid before and during early pregnancy should be advised.

Abstract
OBJECTIVE This study aims to estimate the prevalence of neural tube defects (NTDs) and to identify potential risk factors in the Ethiopian context. STUDY DESIGN Systematic review and meta-analysis. STUDY PARTICIPANTS A total of 611 064 participants were included in the review obtained from 42 studies. METHODS PubMed (Medline), Embase and Cochrane Library databases in combination with other potential sources of literature were systematically searched, whereby studies conducted between January 2010 and December 2022 were targeted in the review process. All observational studies were included and heterogeneity between studies was verified using Cochrane Q test statistics and I2 test statistics. Small study effects were checked using Egger's statistical test at a 5% significance level. RESULT The pooled prevalence of all NTDs per 10 000 births in Ethiopia was 71.48 (95% CI 57.80 to 86.58). The between-study heterogeneity was high (I2= 97.49%, p<0.0001). Birth prevalence of spina bifida (33.99 per 10 000) was higher than anencephaly (23.70 per 10 000), and encephalocele (4.22 per 10 000). Unbooked antenatal care (AOR 2.26, 95% CI (1.30 to 3.94)), preconception intake of folic acid (AOR 0.41, 95% CI (0.26 to 0.66)), having chronic medical illness (AOR 2.06, 95% CI (1.42 to 2.99)), drinking alcohol (AOR 2.70, 95% CI (1.89 to 3.85)), smoking cigarette (AOR 2.49, 95% CI (1.51 to 4.11)), chewing khat (AOR 3.30, 95% CI (1.88 to 5.80)), exposure to pesticides (AOR 3.87, 95% CI (2.63 to 5.71)), maternal age ≥35 (AOR 1.90, 95% CI (1.13 to 3.25)), maternal low educational status (AOR 1.60, 95% CI (1.13 to 2.24)), residing in urban areas (AOR 0.75, 95% CI (0.58 to 0.97))and family history of NTDs (AOR 2.51, 95% CI (1.36 to 4.62)) were associated with NTD cases. CONCLUSION The prevalence of NTDs in Ethiopia is seven times as high as in other Western countries where prevention measures are put in place. Heredity, maternal and environmental factors are associated with a high prevalence of NTDs. Mandatory fortification of staple food with folic acid should be taken as a priority intervention to curb the burden of NTDs. To smoothen and overlook the pace of implementation of mass fortification, screening, and monitoring surveillance systems should be in place along with awareness-raising measures.

Abstract
OBJECTIVE To evaluate the pooled prevalence and identify risk factors of congenital anomalies among neonates in Africa. METHODS The pooled birth prevalence of congenital anomalies was the first outcome of this review, and the pooled measure of association between congenital anomalies and related risk factors in Africa was the second. We conducted a thorough search of the databases PubMed/ Medline, PubMed Central, Hinary, Google, Cochrane Library, African Journals Online, Web of Science and Google Scholar up to 31 January 2023. The JBI appraisal checklist was used to evaluate the studies. STATA V.17 was used for the analysis. The I2 test and Eggers and Beggs tests were used to measure study heterogeneity and publication bias respectively. The pooled prevalence of congenital anomalies was calculated using DerSimonian and Laird random-effect model. Subgroup analysis, sensitivity analysis and meta-regression were also performed. RESULT This systematic review and meta-analysis includes 32 studies with a total of 626 983 participants. The pooled prevalence of congenital anomalies was 23.5 (95% CI 20 to 26.9) per 1000 newborns. Not taking folic acid (pooled OR=2.67; 95% CI (1.42 to 5.00)), history of maternal illness (pooled OR=2.44, 95% CI (1.2 to 4.94)), history of drug use (pooled OR=2.74, 95% CI (1.29 to 5.81)), maternal age (>35 years.) (Pooled OR=1.97, 95% CI (1.15 to 3.37)), drinking alcohol (pooled OR=3.15, 95% CI (1.4 to 7.04)), kchat chewing (pooled OR=3.34, 5% CI (1.68 to 6.65)) and urban residence (pooled OR=0.58, 95% CI (0.36 to 0.95)) were had significant association with congenital anomalies. CONCLUSION The pooled prevalence of congenital abnormalities in Africa was found to be substantial, with significant regional variation. Appropriate folate supplementation during pregnancy, proper management of maternal sickness, proper antenatal care, referring healthcare personnel before using drugs, avoiding alcohol intake and kchat chewing are all important in lowering the occurrence of congenital abnormalities among newborns in Africa.

Abstract
Background Neural tube defects are a type of congenital anomaly caused by an abnormality in the development of the brain and spinal cord during embryogenesis. They cause high rates of mortality, morbidity, and lifelong disability. There are several studies carried out worldwide reporting different findings on the burden and associated factors. The aim of this study is to carry out a systematic review and meta-analysis of the burden of neural tube defects and their associated factors in Africa. Methods A total of 58 eligible articles were identified systematically using databases such as PubMed, Embase, African Journal Online Library, ProQuest, Cochrane, Google Scopus, Google Scholar, and Grey literature. Extracted data were analyzed using STATA 16.0 statistical software. The heterogeneity of studies was determined using the Cochrane Q test statistic and I2 test statistics with forest plots. A random effects model was used to examine the pooled burden of neural tube defects, subgroups of the region, subtypes of NTDs, sensitivity analysis, and publication bias. The association between NTDs and associated factors was studied using a fixed-effect model. Results Fifty-eight studies with a total of 7,150,654 participants in 16 African countries revealed that the pooled burden of neural tube defects was 32.95 per 10,000 births (95% CI: 29.77-36.13). The Eastern African region had the highest burden in the subgroup analysis, with 111.13 per 10,000 births (95% CI: 91.85-130.42). South African countries had the lowest burden, at 11.43 per 10,000 births (95% CI: 7.51-15.34). In subtype analysis, spina bifida had the highest pooled burden at 17.01 per 10,000 births (95 percent CI: 15.00-19.00), while encephalocele had the lowest at 1.66 per 10,000 births (95% CI: 1.12-2.20). Maternal folic acid supplementation (AOR: 0.38; 95% CI: 0.16-0.94), alcohol consumption (AOR: 2.54; 95% CI: 1.08-5.96), maternal age (AOR: 3.54; 95% CI: 1.67-7.47), pesticide exposure (AOR: 2.69; 95% CI: 1.62-4.46), X-ray radiation (AOR: 2.67; 95% CI: 1.05-6.78), and history of stillbirth (AOR: 3.18; 95% CI: 1.11-9.12) were significantly associated with NTDs. Conclusion The pooled burden of NTDs in Africa was found to be high. Maternal age, alcohol consumption, pesticide and X-ray radiation exposure, history of stillbirth, and folic acid supplementation were significantly associated with NTDs.

Prevalence, Pattern, and Outcome of Congenital Anomalies Admitted to a Neonatal Unit in a Low-Income Country-a Ten-Year Retrospective Study. Matern Child Health J 2023; 27:837-849.

Abstract
OBJECTIVE The incidence of congenital abnormalities is highest in low-and-middle-income countries. However, the prevalence, spectrum, trends of neonatal congenital anomalies and their admission outcomes have not been well explored. This study was a 10 year retrospective hospital-based research in a low-income country to address the above. METHODS All infants hospitalized in the Special Care Baby Unit at the Cape Coast Teaching Hospital in Ghana, between 1st January 2010 and 31st December 2019, had their demographic, obstetric, and clinical data recorded. RESULTS Over the decade, 236 neonates with congenital abnormalities were admitted to the unit, accounting for 2.8% of total neonatal admissions and 8.6 per 1000 births. Mortality occurred in 33.2% of neonates with congenital abnormalities, corresponding to 4.6% of all neonatal deaths. Mortality was significantly associated with place of delivery and gravidity of more than five. The commonest anomalies were in the nervous system, particularly neural tube defects, followed by suspected chromosomal abnormalities and then cardiac defects. Neonates with cardiac defects had a higher chance of dying. Health center/clinic delivery proffered a better survival than hospital delivery, but this should be interpreted with caution. CONCLUSION Neural tube defects were the most predominant anomalies; hence, intensification of preconception and antenatal folic acid supplementation is pivotal towards their reduction. Making prenatal screening for early detection of fetal anomalies an integral part of routine antenatal care is also essential. This research was conducted in a single center and did not include stillbirths and abortions so cannot give an accurate estimation of the number of congenital abnormalities in the population. A national registry of congenital anomalies is recommended.

Abstract
INTRODUCTION Ethiopia is one of the countries facing a very high burden of perinatal death in the world. Despite taking several measures to reduce the burden of stillbirth, the pace of decline was not that satisfactory. Although limited perinatal mortality studies were conducted at a national level, none of the studies stressed the timing of perinatal death. Thus, this study is aimed at determining the magnitude and risk factors that are associated with the timing of perinatal death in Ethiopia. METHODS National perinatal death surveillance data were used in the study. A total of 3814 reviewed perinatal deaths were included in the study. Multilevel multinomial analysis was employed to examine factors associated with the timing of perinatal death in Ethiopia. The final model was reported through the adjusted relative risk ratio with its 95% Confidence Interval, and variables with a p-value less than 0.05 were declared statistically significant predictors of the timing of perinatal death. Finally, a multi-group analysis was carried out to observe inter-regional variation among selected predictors. RESULT Among the reviewed perinatal deaths, 62.8% occurred during the neonatal period followed by intrapartum stillbirth, unknown time of stillbirth, and antepartum stillbirth, each contributing 17.5%,14.3%, and 5.4% of perinatal deaths, respectively. Maternal age, place of delivery, maternal health condition, antennal visit, maternal education, cause of death (infection and congenital and chromosomal abnormalities), and delay to decide to seek care were individual-level factors significantly associated with the timing of perinatal death. While delay reaching a health facility, delay to receive optimal care health facility, type of health facility and type region were provincial-level factors correlated with the timing of perinatal death. A statistically significant inter-regional variation was observed due to infection and congenital anomalies in determining the timing of perinatal death. CONCLUSION Six out of ten perinatal deaths occurred during the neonatal period, and the timing of perinatal death was determined by neonatal, maternal, and facility factors. As a way forward, a concerted effort is needed to improve the community awareness of institutional delivery and ANC visit. Moreover, strengthening the facility level readiness in availing quality service through all paths of the continuum of care with special attention to the lower-level facilities and selected poor-performing regions is mandatory.
