Abstract
Birth defects are a leading cause of infant mortality in the United States, but little is known about causes of many types of birth defects. Spatiotemporal disease mapping to identify high-prevalence areas, is a potential strategy to narrow the search for potential environmental and other causes that aggregate over space and time. We described the spatial and temporal trends of the prevalence of birth defects in North Carolina during 2003-2015, using data on live births obtained from the North Carolina Birth Defects Monitoring Program. By employing a Bayesian space-time Poisson model, we estimated spatial and temporal trends of non-chromosomal and chromosomal birth defects. During 2003-2015, 52,524 (3.3%) of 1,598,807 live births had at least one recorded birth defect. The prevalence of non-chromosomal birth defects decreased from 3.8% in 2003 to 2.9% in 2015. Spatial modeling suggested a large geographic variation in non-chromosomal birth defects at census-tract level, with the highest prevalence in southeastern North Carolina. The strong spatial heterogeneity revealed in this work allowed to identify geographic areas with higher prevalence of non-chromosomal birth defects in North Carolina. This variation will help inform future research focused on epidemiologic studies of birth defects to identify etiologic factors.

Is gastroschisis associated with county-level socio-environmental quality during pregnancy? Birth Defects Res 2023; 115:1758-1769. [PMID: 37772934 PMCID: PMC10878499 DOI: 10.1002/bdr2.2250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 08/31/2023] [Indexed: 09/30/2023]
Abstract
BACKGROUND Gastroschisis prevalence more than doubled between 1995 and 2012. While there are individual-level risk factors (e.g., young maternal age, low body mass index), the impact of environmental exposures is not well understood. METHODS We used the U.S. Environmental Protection Agency's Environmental Quality Index (EQI) as a county-level estimate of cumulative environmental exposures for five domains (air, water, land, sociodemographic, and built) and overall from 2006 to 2010. Adjusted odds ratios (aOR) and 95% confidence interval (CI) were estimated from logistic regression models between EQI tertiles (better environmental quality (reference); mid; poorer) and gastroschisis in the National Birth Defects Prevention Study from births delivered between 2006 and 2011. Our analysis included 594 cases with gastroschisis and 4105 infants without a birth defect (controls). RESULTS Overall EQI was modestly associated with gastroschisis (aOR [95% CI]: 1.29 [0.98, 1.71]) for maternal residence in counties with poorer environmental quality, compared to the reference (better environmental quality). Within domain-specific indices, only the sociodemographic domain (aOR: 1.51 [0.99, 2.29]) was modestly associated with gastroschisis, when comparing poorer to better environmental quality. CONCLUSIONS Future work could elucidate pathway(s) by which components of the sociodemographic domain or possibly related psychosocial factors like chronic stress potentially contribute to risk of gastroschisis.

Abstract
INTRODUCTION: Public health officials provide an important public service responding to community concerns around cancer and often receive requests to investigate patterns of cancer incidence and communicate findings with citizens. In this study, we identified procedures Canadian public health officials followed when investigating reports of cancer clusters, and explored the challenges officials faced conducting risk communication with communities. METHODS: Thirteen interviews were administered by telephone with 15 officials across Canadian jurisdictions and analyzed using thematic analysis. A content analysis of procedural documents received from five provinces was also undertaken. RESULTS: A third of provinces/territories in this study did not use any consistent guidelines to investigate reports of cancer clusters, a third used their own guidelines and a third used guidelines from other countries. Each Canadian jurisdiction identified a different agency or individual responsible for investigating cluster inquiries. Officials in most interviews considered public education to be the primary objective of risk communication during an investigation. Officials in only 4 of 13 interviews cited an overall positive response from the public after investigating reports of a cancer cluster. CONCLUSION: Differences in practices used to investigate suspected cancer clusters by public health officials were revealed in this work. Establishing pan-Canadian cancer cluster guidelines could improve procedural consistency across jurisdictions and offer enhanced opportunities to compare cluster responses for evaluation. A reporting system to track reported clusters may improve information sharing between federal, provincial/territorial and local investigators. During formal investigations, face-to-face participatory communication approaches should be explored to improve citizen engagement and manage community concerns.

Abstract
Gastroschisis is a common congenital abdominal wall defect, likely influenced by environmental factors in utero, with increasing prevalence in the United States. Early detection of gastroschisis in utero has become the standard with improved prenatal care and screening. There are multiple surgical management techniques, though sutureless closure is being used more frequently. Postoperative feeding difficulty is common and requires vigilance for complications, such as necrotizing enterocolitis. Infants with simple gastroschisis are expected to have eventual catch-up growth and normal development, while those with complex gastroschisis have higher morbidity and mortality. Management requires collaboration amongst several perinatal disciplines, including obstetrics, maternal fetal medicine, neonatology, pediatric surgery, and pediatric gastroenterology for optimal care and long-term outcomes.

Abstract
BACKGROUND Infants with gastroschisis often experience slow return of bowel function following closure. The purpose of this study was to determine whether exclusive breast milk is associated with decreased time to enteral autonomy. METHODS We conducted a retrospective cohort study of infants with uncomplicated gastroschisis from a tertiary pediatric hospital. The primary outcome was enteral autonomy, defined as days from initiating enteral feeds to stopping parenteral nutrition. Secondary outcomes included days of parenteral nutrition, length of stay, positive culture, necrotizing enterocolitis, cholestasis, additional surgery, readmission, and mortality. RESULTS We identified 100 infants with gastroschisis treated from 2005 to 2019. Twenty-five were excluded due to gestational age <32 weeks, birth weight <1500 g, or gastroschisis-associated complications (e.g., intestinal atresia). Seventy-five were included in the analysis. Mean gestational age was 36 weeks, 48% were female, and all were diagnosed antenatally. Sixty-five infants (87%) received exclusive maternal (n = 64) or donor (n = 1) breast milk, while 10 others (13%) were fed formula for 1-16 days (mean 7 days). Two infants received formula only. Demographics and gastroschisis prognostic scores were similar between groups. Infants who were given breast milk exclusively demonstrated decreased time to enteral autonomy (median 18 versus 25 days, p = 0.023) and shorter duration of parenteral nutrition (median 20 versus 26 days, p = 0.037). CONCLUSION Exclusive breast milk may be associated with improved outcomes among infants with gastroschisis. Further research is needed to evaluate the economic impact of this association and explore possible confounders. These efforts may expand the role of donor breast milk for these patients.

Abstract
With reports from Australia, Canada, USA, Hawaii and Colorado documenting a link between cannabis and congenital anomalies (CAs), this relationship was investigated in Europe. Data on 90 CAs were accessed from Eurocat. Tobacco and alcohol consumption and median household income data were from the World Bank. Amphetamine, cocaine and last month and daily use of cannabis from the European Monitoring Centre for Drugs and Drug Addiction. Cannabis herb and resin Δ9-tetrahydrocannabinol concentrations were from published reports. Data were processed in R. Twelve thousand three hundred sixty CA rates were sourced across 16 nations of Europe. Nations with a higher or increasing rate of daily cannabis use had a 71.77% higher median CA rates than others [median ± interquartile range 2.13 (0.59, 6.30) v. 1.24 (0.15, 5.14)/10 000 live births (P = 4.74 × 10-17; minimum E-value (mEV) = 1.52]. Eighty-nine out of 90 CAs in bivariate association and 74/90 CAs in additive panel inverse probability weighted space-time regression were cannabis related. In inverse probability weighted interactive panel models lagged to zero, two, four and six years, 76, 31, 50 and 29 CAs had elevated mEVs (< 2.46 × 1039) for cannabis metrics. Cardiovascular, central nervous, gastrointestinal, genital, uronephrology, limb, face and chromosomalgenetic systems along with the multisystem VACTERL syndrome were particularly vulnerable targets. Data reveal that cannabis is related to many CAs and fulfil epidemiological criteria of causality. The triple convergence of rising cannabis use prevalence, intensity of daily use and Δ9-tetrahydrocannabinol concentration in herb and resin is powerfully implicated as a primary driver of European teratogenicity, confirming results from elsewhere.

Abstract
BACKGROUND Previous studies showed increases in rates of gastroschisis in Canada in the first decade of the 21st century. OBJECTIVE We sought to examine the epidemiologic characteristics of gastroschisis in Canada in recent years. METHODS We conducted a retrospective population-based cohort study of all livebirths and stillbirths delivered in Canada (excluding Quebec) from 2006 to 2017, with information obtained from the Canadian Institute for Health Information. Gastroschisis rates by maternal age, region of residence, and maternal and infant characteristics were quantified using prevalence rate ratios (RR) and 95% confidence intervals (CI). Log-binomial regression was used to quantify the associations between risk factors and gastroschisis. RESULTS There were 1314 gastroschisis cases among 3 364 116 births. The prevalence rate was 3.7 per 10 000 total births in 2006 and 3.4 per 10 000 total births in 2017, with substantial annual variation in rates. The proportion of mothers aged 20-24 years decreased from 16.5% in 2006 to 11.3% in 2017, while the proportion of mothers aged <20 years halved from 4.8% to 2.3%. The prevalence of gastroschisis at birth remained unchanged among mothers aged <20, 20-24 and 30-49 years but increased among mothers aged 25-29 years. The age-adjusted prevalence rate of gastroschisis increased across the period (for 2016-2017 versus 2006-2007 rate ratio [RR] 1.28, 95% CI 1.05, 1.56), and there was substantial regional variation. Risk factors included problematic use of substances (RR 2.61, 95% CI 2.01, 3.39) and hypothyroidism (RR 2.76, 95% CI 1.56, 4.88). There was a North-to-South difference in gastroschisis prevalence (adjusted RR Far North compared with South 1.54, 95% CI 1.11, 2.15). CONCLUSION Gastroschisis birth prevalence rates in Canada have stabilised in recent years compared with the increase documented previously. The substantial geographic variation and North-to-South difference in gastroschisis prevalence may indicate variation in socio-economic status, lifestyle and nutritional patterns.

Abstract
Gastroschisis (GS) is a full-thickness abdominal wall defect in which fetal intestine herniates alongside the umbilical cord into the intrauterine cavity, resulting in an intestinal injury of variable severity. An increased prevalence of gastroschisis has been observed across several continents and is a focus of epidemiologic study. Prenatal diagnosis of GS is common and allows for delivery planning and treatment in neonatal intensive care units (NICUs) by collaborative interdisciplinary teams (neonatology, neonatal nursing and pediatric surgery). Postnatal treatment focuses on closure of the defect, optimized nutrition, complication avoidance and a timely transition to enteral feeding. Babies born with complex GS are more vulnerable to complications, have longer and more resource intensive hospital stays and benefit from standardized care pathways provided by teams with expertise in managing infants with intestinal failure. This article will review the current state of knowledge related to the medical and surgical management and outcomes of gastroschisis with a special focus on the role of the neonatologist in supporting integrated team-based care.

Abstract
BACKGROUND The etiologies of major birth defects are still unclear and few spatial analyses have been conducted in the United States. Spatial analyses of individual-level data can help elucidate environmental and social risk factors. METHODS We used generalized additive models to analyze 52,955 cases of neural tube defects, congenital heart defects (CHDs), gastroschisis, and orofacial cleft defects, and sampled from 642,399 controls born between 1999 and 2011 in Texas. The effect of geographic location was measured using a bivariable smooth term of geocoded birth address within a logistic regression framework. We calculated and mapped odds ratios (ORs) and 95% confidence intervals (CIs) for birth defects subtypes across Texas, and adjusted for maternal characteristics, environmental indicators, and community-level covariates. We also performed time-stratified spatiotemporal analyses for more prevalent birth defects. RESULTS Location was significantly associated with crude odds of all birth defects except hypoplastic left heart syndrome. After adjusting for maternal characteristics, environmental indicators, and community-level factors, ORs in many geographic areas were no longer statistically significant for most defects, especially CHDs. However, areas of significant and insignificant elevated risk remained for defects in all groups in North and South Texas, with ORs for ventricular septal defects increasing over time. Low risk of birth defects was often present in the northern part of East Texas. CONCLUSION Significant spatial patterns of birth defects were identified and varied depending on adjustment of different categories of covariates. Further investigation of areas with increased risks may aid in our understanding of birth defects.

Abstract
OBJECTIVES Cannabis is a known teratogen. Data availability addressing both major congenital anomalies and cannabis use allowed us to explore their geospatial relationships. METHODS Data for the years 1998 to 2009 from Canada Health and Statistics Canada was analyzed in R. Maps have been drawn and odds ratios, principal component analysis, correlation matrices, least squares regression and geospatial regression analyses have been conducted using the R packages base, dplyr, epiR, psych, ggplot2, colorplaner and the spml and spreml functions from package splm. RESULTS Mapping showed cannabis use was more common in the northern Territories of Canada in the Second National Survey of Cannabis Use 2018. Total congenital anomalies, all cardiovascular defects, orofacial clefts, Downs syndrome and gastroschisis were all found to be more common in these same regions and rose as a function of cannabis exposure. When Canada was dichotomized into high and low cannabis use zones by Provinces v Territories the Territories had a higher rate of total congenital anomalies 450.026 v 390.413 (O.R. = 1.16 95%C.I. 1.08-1.25, P = 0.000058; attributable fraction in exposed 13.25%, 95%C.I. 7.04-19.04%). In geospatial analysis in a spreml spatial error model cannabis was significant both alone as a main effect (P < 2.0 × 10) and in all its first and second order interactions with both tobacco and opioids from P < 2.0 × 10. CONCLUSION These results show that the northern Territories of Canada share a higher rate of cannabis use together with elevated rates of total congenital anomalies, all cardiovascular defects, Down's syndrome and gastroschisis. This is the second report of a significant association between cannabis use and both total defects and all cardiovascular anomalies and the fourth published report of a link with Downs syndrome and thereby direct major genotoxicity. The correlative relationships described in this paper are confounded by many features of social disadvantage in Canada's northern territories. However, in the context of a similar broad spectrum of defects described both in animals and in epidemiological reports from Hawaii, Colorado, USA and Australia they are cause for particular concern and indicate further research.

Abstract
BACKGROUND Gastroschisis is a congenital anomaly of the abdomen in which the intestines are found outside of the body at birth. While no clear causative factors have been identified, it is strongly associated with young maternal age. Other reported associations include low maternal socioeconomic status, low maternal body mass index (BMI), and smoking. METHODS This is a retrospective review of epidemiologic data relating to cases of gastroschisis in Ontario from 2012-2018 in the Better Outcomes Registry & Network (BORN) Ontario database, which is the province's prescribed maternal-newborn registry. We describe the epidemiology of gastroschisis in Ontario with respect to birth prevalence, maternal age, health, exposures, and geography. RESULTS The birth prevalence of gastroschisis is 2.31 cases/10,000 births. There was no apparent change in birth prevalence over the study period and there was no difference between male and female infants. Gastroschisis was associated with younger maternal ages and was inversely correlated with maternal BMI. Gastroschisis was associated with first completed pregnancy. Maternal diabetes was associated with a lower birth prevalence of gastroschisis than average. Mothers of babies with gastroschsis were more likely to report use of tobacco, alcohol, and drugs during pregnancy than those without gastroschisis, with marijuana use showing the largest increase in birth prevalence of gastroschisis. Mothers living in rural areas were more likely to have a baby with gastroschisis than those in urban centers, even after controlling for maternal age. CONCLUSIONS This Ontario registry study reveals that mothers with babies with gastroschisis are more likely to be young and thin, live in rural areas, and report prenatal smoking, alcohol use, and drug use than women whose pregnancies do not have gastroschsis.

Gastroschisis: A State-of-the-Art Review. CHILDREN-BASEL 2020; 7:children7120302. [PMID: 33348575 PMCID: PMC7765881 DOI: 10.3390/children7120302] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 12/08/2020] [Accepted: 12/14/2020] [Indexed: 01/17/2023]
Abstract
Gastroschisis, the most common type of abdominal wall defect, has seen a steady increase in its prevalence over the past several decades. It is identified, both prenatally and postnatally, by the location of the defect, most often to the right of a normally-inserted umbilical cord. It disproportionately affects young mothers, and appears to be associated with environmental factors. However, the contribution of genetic factors to the overall risk remains unknown. While approximately 10% of infants with gastroschisis have intestinal atresia, extraintestinal anomalies are rare. Prenatal ultrasound scans are useful for early diagnosis and identification of features that predict a high likelihood of associated bowel atresia. The timing and mode of delivery for mothers with fetuses with gastroschisis have been somewhat controversial, but there is no convincing evidence to support routine preterm delivery or elective cesarean section in the absence of obstetric indications. Postnatal surgical management is dictated by the condition of the bowel and the abdominal domain. The surgical options include either primary reduction and closure or staged reduction with placement of a silo followed by delayed closure. The overall prognosis for infants with gastroschisis, in terms of both survival as well as long-term outcomes, is excellent. However, the management and outcomes of a subset of infants with complex gastroschisis, especially those who develop short bowel syndrome (SBS), remains challenging. Future research should be directed towards identification of epidemiological factors contributing to its rising incidence, improvement in the management of SBS, and obstetric/fetal interventions to minimize intestinal damage.

J Pediatr Surg 2020; 55:493-512. [PMID: 31839371 DOI: 10.1016/j.jpedsurg.2019.11.001] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Revised: 11/02/2019] [Accepted: 11/05/2019] [Indexed: 12/20/2022]
Abstract
PURPOSE Low- and middle-income countries (LMICs) have only 19% of the global surgical workforce yet see 80% of worldwide deaths from noncommunicable diseases. We aimed to interrogate the correlation between pediatric surgical workforce density (PSWD) and survival from pediatric surgical conditions worldwide. METHODS A systematic review of online databases identified outcome studies for key pediatric surgical conditions (gastroschisis, esophageal atresia, intestinal atresia, and typhoid perforation) as well as PSWD data across low-income (LICs), middle-income (MICs), and high-income countries (HICs). PSWD was expressed as the number of PSs/million children under 15 years of age and we correlated this to surgical outcomes for our case series. RESULTS PSWD ranged between zero (Burundi, The Gambia, and Mauritania) and 125.2 (Poland) across 86 countries. Outcomes for at least one condition were obtained in 61 countries: 50 outcomes in HICs, 52 in MICs and 8 in LICs. The mean survival in our case series was 42.3%, 69.4% and 91.6% for LICs, MICs, and HICs, respectively. A PSWD ≥4 PSs/million children under 15 years of age significantly correlated to odds of survival ≥80% (OR 16.8, p < 0.0001, 95% CI 5.66-49.88). Specifically in the studied LICs and MICs, increasing the PSWD to 4 would require training 1427 additional surgeons. CONCLUSION Using a novel approach, we have established a benchmark for the scale-up of pediatric surgical workforce, which may support broader efforts to reduce childhood deaths from congenital disease.

Spatial Clusters of Children with Cleft Lip and Palate and Their Association with Polluted Zones in the Monterrey Metropolitan Area. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16142488. [PMID: 31336885 PMCID: PMC6678111 DOI: 10.3390/ijerph16142488] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/02/2019] [Revised: 06/27/2019] [Accepted: 07/09/2019] [Indexed: 11/17/2022]
Abstract
This study examines the spatial structure of children with cleft lip and palate (CLP) and its association with polluted areas in the Monterrey Metropolitan Area (MMA). The Nearest Neighbor Index (NNI) and the Spatial Statistical Scan (SaTScan) determined that the CLP cases are agglomerated in spatial clusters distributed in different areas of the city, some of them grouping up to 12 cases of CLP in a radius of 1.2 km. The application of the interpolation by empirical Bayesian kriging (EBK) and the inverse distance weighted (IDW) method showed that 95% of the cases have a spatial interaction with values of particulate matter (PM10) of more than 50 points. The study also shows that 83% of the cases interacted with around 2000 annual tons of greenhouse gases. This study may contribute to other investigations applying techniques for the identification of environmental and genetic factors possibly associated with congenital malformations and for determining the influence of contaminating substances in the incidence of these diseases, particularly CLP.

Abstract
Background Gastroschisis is a congenital anomaly of the fetal abdominal wall, usually to the right side of umbilical insertion. It is often detected by routine antenatal ultrasound. Significant maternal and pediatric resources are utilised in the care of women and infants with gastroschisis. Increasing rates of gastroschisis worldwide have led institutions to review local data and investigate outcomes. A collaborative project was developed to review local epidemiology and investigate antenatal and neonatal factors influencing hospital length of stay (LOS) and total parental nutrition (TPN) in infants born with gastroschisis. Methods We performed a five-year review of infants born with gastroschisis (2011–2015) at a major Australian centre. Complex gastroschisis was defined as involvement of stenosis, atresia, ischemia, volvulus or perforation and closed or vanishing gastroschisis. We extracted data from files and databases at the two participating hospitals, a major maternal fetal medicine centre and the affiliated children’s hospital. Results There were 56 infants antenatally diagnosed with gastroschisis with no terminations, one stillbirth (2%) and one infant with ‘vanishing’ gastroschisis. The mean maternal age was 23.9 years (range, 15–39 years). The mean gestation at delivery was 36 weeks (range, 25–39+ 3 weeks). Of the 55 neonates who received surgical management, 62% had primary closure. The median LOS was 33 (IQR, 23–45) days and the median duration of TPN was 26 (IQR, 17–36) days. Longer days on TPN (median 35 vs 16 days, P = 0.03) was associated with antenatal finding of multiple dilated bowel loops. Postnatal diagnosis of complex gastroschisis was made in 16% of cases and was associated with both longer LOS (median 89 vs 30 days, P = 0.003) and days on TPN (median 46 vs 21 days, P = 0.009). Conclusion Complex gastroschisis was associated with greater days on TPN and LOS. We found no late-gestation stillbirths and a low overall rate of 1.8%, suggesting the risk for stillbirth associated with gastroschisis is lower than previously documented. This information may assist counselling families. Improved data collection worldwide may reveal causative factors and enable antenatal outcome predictors.

Abstract
STUDY OBJECTIVE To explore the prevalence, mortality, and spatial distribution of gastroschisis using a large population-based sample with cases identified according to birth and death certificates (ICD-10 diagnosis code Q79.3, gastroschisis) through the General Directorate of Health Information of the Secretary Health of Mexico, over the course of a 15-year period. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A descriptive study examining 10,287 cases of gastroschisis was performed from 2000-2014 using public natality data for denominators (more than 25 million live births). Gastroschisis prevalence and mortality was calculated for each of year, state, maternal, and newborn characteristics. Spatial distribution was analyzed according to gastroschisis prevalence in the 32 states of Mexico. RESULTS Gastroschisis prevalence was 4.01 per 10,000 live births (annual trend 2.09-6.85). Mortality associated with gastroschisis was 1.28 per 10,000 live births. Women younger than 20 years old, primiparae, and preterm infants had the highest gastroschisis-related prevalence (13.12, 5.83, and 7.51 per 10,000 live births, respectively). Gastroschisis prevalence and mortality did not differ according to newborn sex. A negative binomial distribution, variance (82,391.87) greater than the mean (321.47) was identified. CONCLUSION Our findings show an increasing temporal trend for gastroschisis since 2000 in Mexico. Additionally, gastroschisis might follow in future instances a positive binomial or Poisson distribution. Therefore, improving surveillance of risk factors and supporting research for gastroschisis is warranted among maternal age younger than 25, particularly, younger than 20 years of age.

Abstract
Pediatric surgeons treat a variety of conditions that are distinguished by their low occurrence rate, complexity, and need for integrated multidisciplinary care. Although randomized controlled trials (RCTs) are considered the gold standard for generating evidence to inform best practice, they are poorly suited to rare diseases based on the variability of illness severity, unpredictability in clinical course, and the impact limitations of studying a single intervention at a time. An alternative to RCTs for comparative effectiveness research for rare diseases in pediatric surgery is the patient registry, which collects detailed and condition-specific patient level data related to illness severity, treatment, and outcome, and allows a large, disease-specific database to be created for the dual purposes of collaborative research and quality improvement across participating sites. This review discusses the various functions of a patient registry in fulfilling its mandate of evidence-based practice and outcome improvement using examples from a variety of existing pediatric surgical registries. The value proposition of patient registries as sources of knowledge, facilitators of practice standardization, and enablers of continuous quality improvement is discussed.

Abstract
Gastroschisis is the commonest developmental defect of the anterior abdominal wall in both developed and developing countries. The past 30 years have seen transformational improvements in outcome due to advances in neonatal intensive care and enhanced integration between the disciplines of maternal fetal medicine, neonatology and pediatric surgery. A review of gastroschisis, which emphasizes its epidemiology, multidisciplinary care strategies and contemporary outcomes is timely. Areas covered: This review discusses the current state of knowledge related to prevalence and causation, and postulated embryopathologic mechanisms contributing to the development of gastroschisis. Using relevant, current literature with an emphasis on high level evidence where it exists, we review modern techniques of prenatal diagnosis, pre and postnatal risk stratification, preferred timing and method of delivery, options for abdominal wall closure, nutritional management, and short and long term clinical and neurodevelopmental follow-up. Expert commentary: This section explores controversies in contemporary management which contribute to practice and cost variation and discusses the benefits of novel nutritional therapies and care standardization that target unnecessary practice variation and improve overall cost-effectiveness of gastroschisis care. The commentary concludes with a review of fertile areas of gastroschisis research, which represent opportunities for knowledge synthesis and further outcome improvement.
