Abstract
BACKGROUND AND OBJECTIVES Neural tube defects (NTDs) are an important cause of global morbidity worldwide. Well-planned global neurosurgery and public health efforts can aid vulnerable communities, but there is a need to elucidate the global burden of NTDs and identify regions without available data to better target interventions. METHODS A scoping review to quantify worldwide NTD prevalence using the PubMed/Medline and birth defects surveillance registries was conducted. Data published after January 1, 1990, encompassing prevalence values of at least the 2 most prevalent NTDs-spina bifida and encephalocele-were abstracted. Average NTD prevalence rates were aggregated by World Health Organization (WHO) region and World Bank classification, and differences were determined using the analysis of variance test. Differences in availability of nationally representative data by WHO region and World Bank classification were determined using χ2 tests. RESULTS This review captured 140 studies from a total of 93 of 194 WHO member countries. The percentage of countries within a geographic region with available NTD prevalence data was highest in the Eastern Mediterranean (EMR) (85.7%) and lowest in Africa (AFR) (31.3%). The NTD prevalence range was 0.9-269.6 per 10 000 births. Statistically significant differences in reported NTD prevalence rates existed by WHO Region (P = .00027) and World Bank income level of study country (P = .00193). Forty countries (43%) had conducted national-level studies assessing NTD prevalence. There was a statistically significant difference in the availability of nationally representative prevalence data depending on the WHO region (P = .0081) and World Bank classification of study country (P = .0017). CONCLUSION There is a gap in availability of NTD prevalence data worldwide, with many WHO member states lacking national-level NTD prevalence estimates. These findings highlight the need for greater NTD surveillance efforts to identify the countries with the greatest need for targeted global intervention.

Abstract
INTRODUCTION Surgically correctable congenital anomalies are responsible for a significant burden of morbidity and mortality in children from low-and lower-middle-income countries (LMICs). Early identification through fetal and neonatal screening is critical to reducing death and disability. This study aims to identify feasible screening methods for surgically correctable congenital anomalies in LMICs. METHODS A systematic search looking at screening for congenital anomalies in LMIC was conducted in seven databases from 2000 until May 25, 2020, with no language restriction. All articles discussing screening methods for surgically correctable congenital anomalies in LMICs were included. Articles were screened by two independent contributors using Rayyan software, with a third contributor resolving conflicts. Feasibility of the screening method and its risk of bias were assessed using the MINORS scale. RESULTS Of 3473 articles, 24 were included in the full-text review. Nine screening methods (three prenatal and six postnatal) were identified - the most frequently utilized being physician clinical examination (45.8%), pulse oximetry (33.3%) and fetal ultrasound (20.8%). The use of a birth defect picture toolkit was the most feasible screening method. The risk of bias scale yielded an average of 11.9 points, which corresponds to a moderate level of bias. CONCLUSION Despite clear benefits, prenatal and neonatal screening methods are infrequently used in LMICs to identify surgically correctable congenital anomalies in neonates, likely due to financial, material, and human resource constraints. Further research into the development of low-cost feasible methods is needed within these settings. PROSPERO REGISTRATION NUMBER CRD42020192051. TYPE OF STUDY Systematic review. LEVEL OF EVIDENCE IV.

Abstract
Objectives To determine the birth prevalence, trend, and characteristics of external structural birth defects occurrence in Enugu Metropolis, Nigeria. Design Cross-sectional study involving review of delivery records. Setting The study was conducted at three tertiary hospitals, one public and two missionary, in Enugu Metropolis. Participants Mothers and their babies delivered between 1 January 2009 and 31 December 2016 in the study facilities. Main outcome measures Birth prevalence of defects presented as frequency/10,000 births. Other descriptive variables are presented as frequencies and percentages. Results There were 21530 births with 133 birth defects (birth prevalence: 61.8/10,000 births) and 1176 stillbirths (stillbirth rate: 54.6/1000 births). The frequencies and birth prevalence (/10,000 births) of recorded defects were: Limb deformities 60(27.9), Neural tube defects (NTDs): 36(16.7), Urogenital system defects: 12(5.6), Gastrointestinal system defects 10(4.6) and Orofacial clefts 4(1.9). Birth defects occurrence showed a rising trend from 2009 to 2016. The mean (SD) age of mothers whose babies had Birth defects was 29.1(4.7) years. Only 62(46.6%) of 133 antenatal clinic folders of these women were traceable for further review. Eighteen (29.0%) had febrile illness in early pregnancy, 9(14.5%) had Malaria, 17(27.4%) had <4 antenatal clinic attendance, 7(11.3%) did not take folic acid and 6(9.7%) took herbal medications during pregnancy. Conclusions Birth defects occurrence showed a rising trend with limb deformities and NTDs having the highest prevalence. Record keeping was poor at the facilities. Birth defects preventive interventions like folic acid supplementation for women-of-childbearing age should be promoted in Enugu Metropolis. Funding This work was supported by the non-communicable disease Minigrant from the Task Force for Global Health, Decatur, Georgia, USA (TPN-FE-NCD-C2-IFO-9).

Abstract
Introduction Birth defects are the most serious causes of infant mortality and disability in sub-Saharan African countries with variable magnitude. Hence, this study was aimed to determine the pooled prevalence of birth defects and its associated risk factors among newborn infants in sub-Saharan African countries. Methods A total of 43 eligible studies were identified through literature search from Medline (PubMed), EMBASE, HINARI, Google scholar, Science Direct, Cochrane Library and other sources. Extracted data were analyzed using STATA 15.0 statistical software. A random effect meta-analysis model was used. Results Twenty-five studies in 9 countries showed that the pooled prevalence of birth defects was 20.40 per 1,000 births (95% CI: 17.04, 23.77). In the sub-group analysis, the highest prevalence was observed in southern Africa region with a prevalence of 43 per 1000 (95% CI: 14.89, 71.10). The most prevalent types of birth defects were musculo-skeletal system defects with a pooled prevalence of 3.90 per 1000 (95% CI: 3.11, 4.70) while the least was Down syndrome 0.62 per 1000 (95% CI: 0.40, 0.84). Lack of folic acid supplementation (95% CI: 1.95, 7.88), presence of chronic disease (95% CI: 2.00, 6.07) and intake of drugs (95% CI: 3.88, 14.66) during pregnancy were significantly associated with the birth defects. Conclusion The prevalence of birth defects is relatively high with high degree of regional variabilities. The most common types of birth defects were musculoskeletal defects. Lack of folic acid supplementation, presence of chronic disease and intake of drugs during pregnancy were significantly associated with birth defects.

Abstract
Periconceptional folic acid (FA) supplementation is recommended to prevent neural tube defects (NTDs), but little information is known about its use in Vietnam. It is important that FA supplements start to be taken when planning a pregnancy and continued through the first trimester to prevent NTDs, as the neural tube closes in the first month of pregnancy. However, FA supplementation in Vietnam is usually recommended to commence from the first antenatal visit, which is usually at 16 weeks, and very few women take FA before their first visit. This multicenter study aimed to determine the prevalence of FA supplement use and associated maternal characteristics in Vietnam. FA supplementation was assessed in 2030 singleton pregnant women between 2015 and 2016. In total, 654 (32.2%) women reported taking either supplements containing FA alone or multivitamins containing FA, and 505 (24.9%) reported correctly taking supplements containing FA alone. Women who were aged 30 years or over, had low education levels, had formal employment, and whose current pregnancy was first or unplanned were less likely to supplement with FA. Education programs are needed to encourage FA supplementation when contemplating pregnancy.

Thong MK. Achieving the targets of sustainable development goals (2030 agenda) for congenital disorders in Asia: Bottlenecks and interventions. AMERICAN JOURNAL OF MEDICAL GENETICS PART C-SEMINARS IN MEDICAL GENETICS 2019; 181:254-261.

Abstract
The United Nations General Assembly adopted the 2030 Agenda for Sustainable Development in November 2015 which included a set of 17 measurable "sustainable development goals" (SDGs). The SDGs included targets to end preventable deaths of newborns and children under 5 years of age by 2030, universal health care coverage, reduction of premature mortality from noncommunicable diseases (NCDs) by 33% as well as support the development and research for medicines for both communicable and NCDs. Although some successes were achieved in combating communicable diseases and improved childhood mortality rates, health systems in Asia are generally characterized by lack of accurate epidemiological information on congenital disorders, lack of human and financial resources, and inadequate focus on public health strategies to ensure targeted interventions, low level knowledge on congenital disorders amongst the community and healthcare providers and the ethical dilemma of managing rare congenital disorders in an environment of low national health expenditures. These bottlenecks must be addressed systematically and interventions such as the use of innovative epidemiological tools to overcome lack of data, increased efforts to standardize rare disease nomenclature and classification and renewed interest in birth defects registries by countries in the region must be considered. Targeted curative and public health approaches currently used in thalassaemia and neural tube defects may be used for other congenital disorders in Asian countries. The implementation of congenital disorders-related research, prevention, care, and treatment delivery services must be integrated into existing health systems in order to be effective to achieve the targets of SDG2030.

Abstract
BACKGROUND The causes of birth defects (BDs) are complex and include genetic and environmental factors and/or their interactions. More research is needed to describe the epidemiology of BDs within specific regions of China. This study focused on differences in the prevalence of BDs based on ethnicity in a large city in Guangxi Province, China. METHODS Surveillance data of infants born in 114 registered hospitals in Liuzhou between 2011 and 2015 were analyzed to determine the epidemiology of BDs across five major ethnic groups. We calculated the prevalence of BDs and relative risk of BDs by ethnicity. RESULTS There were 260,722 perinatal infants of which 6581 had BDs, with the average prevalence of 25.24 per 1000 perinatal infants (PIs). Prevalence data showed an obvious uptrend over the past 5 years. Han had the highest prevalence of total BDs (28.98‰), followed by Zhuang (25.19‰), Yao (18.50‰), Miao (15.78‰) and Dong (14.24‰). Relative to the Han; Zhuang, Miao, Yao, and Dong had a lower risk of musculoskeletal and urogenital malformations; Miao and Yao had a lower risk of cardiovascular malformation; and Dong had a lower risk of cardiovascular and craniofacial malformation. Several maternal risk factors were found to be associated with BDs (e.g., maternal and gestational age, number of antenatal care visits). CONCLUSION This study provided a comprehensive description of ethnic differences in the risk of BDs in Liuzhou City, China. Observed ethnic differences in the risk of BDs may be related to genetic susceptibilities, environment, cultural customs, or to potential combinations of these factors.

Abstract
To evaluate the association between the single nucleotide polymorphism (SNP) rs227493 in the MEOX2 gene and nonsyndromic cleft palate only, this research was conducted as a case-control study by comparing a nonsyndromic cleft palate only group with an independent, healthy, and unaffected control group who were both examined by specialists. Based on clinical examination and medical records, we analyzed a total of 570 DNA samples, including 277 cases and 293 controls, which were extracted from dry blood spot samples collected from both the Odonto and Maxillofacial Hospital in Ho Chi Minh City and Nguyen Dinh Chieu Hospital in Ben Tre province, respectively. The standard procedures of genotyping the specific SNP (rs2237493) for MEOX2 were performed on a StepOne Realtime PCR system with TaqMan SNP Genotyping Assays. Significant statistical differences were observed in allelic frequencies (allele T and allele G) between the non-syndromic cleft palate only and control groups in female subjects, with an allelic odds ratio of 1.455 (95% confidence interval: 1.026-2.064) and P < 0.05. These study findings suggest that nonsyndromic isolated cleft palate might be influenced by variation of MEOX2, especially SNP rs2237493 in Vietnamese females.

Abstract
OBJECTIVE Congenital talipes equinovarus (CTEV), or clubfoot, is a structural malformation that develops early in gestation. Birth prevalence of clubfoot is reported to vary both between and within low- and middle-income countries (LMICs), and this information is needed to plan treatment services. This systematic review aimed to understand the birth prevalence of clubfoot in LMIC settings. METHODS Six databases were searched for studies that reported birth prevalence of clubfoot in LMICs. Results were screened and assessed for eligibility using pre-defined criteria. Data on birth prevalence were extracted and weighted pooled estimates were calculated for different regions. Wilcoxon rank-sum test was used to examine changes in birth prevalence over time. Included studies were appraised for their methodological quality, and a narrative synthesis of findings was conducted. RESULTS Forty-eight studies provided data from 13 962 989 children in 20 countries over 55 years (1960-2015). The pooled estimate for clubfoot birth prevalence in LMICs within the Africa region is 1.11 (0.96, 1.26); in the Americas 1.74 (1.69, 1.80); in South-East Asia (excluding India) 1.21 (0.73, 1.68); in India 1.19 (0.96, 1.42); in Turkey (Europe region) 2.03 (1.54, 2.53); in Eastern Mediterranean region 1.19 (0.98, 1.40); in West Pacific (excluding China) 0.94 (0.64, 1.24); and in China 0.51 (0.50, 0.53). CONCLUSION Birth prevalence of clubfoot varies between 0.51 and 2.03/1000 live births in LMICs. A standardised approach to the study of the epidemiology of clubfoot is required to better understand the variations of clubfoot birth prevalence and identify possible risk factors.

Ha BTT, Huong NTT, Duong DTT. Prenatal diagnostic services in three regional centers in Vietnam. Int J Public Health 2016; 62:27-33. [PMID: 27628489 DOI: 10.1007/s00038-016-0897-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2016] [Revised: 08/16/2016] [Accepted: 09/03/2016] [Indexed: 12/01/2022] Open
Abstract
OBJECTIVES This study aims to give information on the prenatal diagnostic (PND) services provided in three major regional PND centers in Vietnam. METHODS This cross-sectional study was conducted in early 2014. An inventory of services, human resources, facilities, and equipment and in-depth interviews were carried out. RESULTS Three regional PND centers were set up between 2007 and 2014, and technical guidelines on PND tests were released by the Ministry of Health in 2010. There were a variety of services among centers, and the number of services provided by the three PND centers was far below the target set by the Ministry of Health. There is still limited capacity of human resources, facilities, and equipment in PND centers. Different measures were implemented by hospitals to improve capacity, including counseling. CONCLUSIONS Despite a late start, with government support, PND services in Vietnam have developed quickly. However, to reach the objectives of 15 % of women receiving PND services by 2015 and 50 % by 2020, several actions should be taken to expand the service coverage and capacity of centers.

PLoS One 2016; 11:e0151586.

Abstract
BACKGROUND Folate-sensitive neural tube defects (NTDs) are an important, preventable cause of morbidity and mortality worldwide. There is a need to describe the current global burden of NTDs and identify gaps in available NTD data. METHODS AND FINDINGS We conducted a systematic review and searched multiple databases for NTD prevalence estimates and abstracted data from peer-reviewed literature, birth defects surveillance registries, and reports published between January 1990 and July 2014 that had greater than 5,000 births and were not solely based on mortality data. We classified countries according to World Health Organization (WHO) regions and World Bank income classifications. The initial search yielded 11,614 results; after systematic review we identified 160 full text manuscripts and reports that met the inclusion criteria. Data came from 75 countries. Coverage by WHO region varied in completeness (i.e., % of countries reporting) as follows: African (17%), Eastern Mediterranean (57%), European (49%), Americas (43%), South-East Asian (36%), and Western Pacific (33%). The reported NTD prevalence ranges and medians for each region were: African (5.2-75.4; 11.7 per 10,000 births), Eastern Mediterranean (2.1-124.1; 21.9 per 10,000 births), European (1.3-35.9; 9.0 per 10,000 births), Americas (3.3-27.9; 11.5 per 10,000 births), South-East Asian (1.9-66.2; 15.8 per 10,000 births), and Western Pacific (0.3-199.4; 6.9 per 10,000 births). The presence of a registry or surveillance system for NTDs increased with country income level: low income (0%), lower-middle income (25%), upper-middle income (70%), and high income (91%). CONCLUSIONS Many WHO member states (120/194) did not have any data on NTD prevalence. Where data are collected, prevalence estimates vary widely. These findings highlight the need for greater NTD surveillance efforts, especially in lower-income countries. NTDs are an important public health problem that can be prevented with folic acid supplementation and fortification of staple foods.

Abstract
The 40th anniversary of the end of the Vietnam War is a useful time to review the adverse health consequences of that war and to identify and address serious problems related to armed conflict, such as the protection of noncombatant civilians. More than 58,000 U.S. servicemembers died during the war and more than 150,000 were wounded. Many suffered from posttraumatic stress disorders and other mental disorders and from the long-term consequences of physical injuries. However, morbidity and mortality, although difficult to determine precisely, was substantially higher among the Vietnamese people, with at least two million of them dying during the course of the war. In addition, more than one million Vietnamese were forced to migrate during the war and its aftermath, including many "boat people" who died at sea during attempts to flee. Wars continue to kill and injure large numbers of noncombatant civilians and continue to damage the health-supporting infrastructure of society, expose civilians to toxic chemicals, forcibly displace many people, and divert resources away from services to benefit noncombatant civilians. Health professionals can play important roles in promoting the protection of noncombatant civilians during war and helping to prevent war and create a culture of peace.
