Genitourinary infection and gastroschisis: A systematic review and meta-analysis.

BACKGROUND: Gastroschisis is a congenital anomaly of the umbilical ring with increasing prevalence, especially amongst younger mothers. There is increasing evidence that exposure to genitourinary infections (GUTI) may play an important role in the etiology of gastroschisis. This systematic review and meta-analysis aimed to identify, appraise, and summarize the literature on exposure to GUTI and gastroschisis. METHODS: Six electronic databases (MEDLINE, EMBASE, Web of Science, Scopus, Cochrane Library electronic databases, and Prospero) were searched using a comprehensive search strategy. Citations and cited articles for all included studies were searched. Peer-reviewed, quantitative studies reporting an association of urinary tract infections (UTI) and/or sexually transmitted infections (STI) with gastroschisis were included. Prospero registration CRD42022377420. RESULTS: A total of 2392 papers were identified via the searches of which 15 met our inclusion criteria and were included after title and abstract and full text screening. The study period for included studies ranged from 1995 to 2016, most were from the USA. Four studies considering exposure to STIs and five to UTIs were eligible to progress to meta-analysis. Meta-analysis identified a significantly increased risk of gastroschisis in association with periconceptional exposure to UTI [OR 1.54 (95% CI 1.29, 1.8)], STI [OR 1.4 (95% CI 1.01, 1.79)]. CONCLUSIONS: Periconceptional exposure to GUTI is associated with an increased risk of gastroschisis. The prevention and timely treatment of GUTI amongst women of childbearing age may help to reduce the occurrence of gastroschisis.

Use of a new vertical traction device for early traction-assisted staged closure of congenital abdominal wall defects: a prospective series of 16 patients.

PURPOSE: Abdominal wall closure in patients with giant omphalocele (GOC) and complicated gastroschisis (GS) remains to be a surgical challenge. To facilitate an early complete abdominal wall closure, we investigated the combination of a staged closure technique with continuous traction to the abdominal wall using a newly designed vertical traction device for newborns. METHODS: Four tertiary pediatric surgery departments participated in the study between 04/2022 and 11/2023. In case primary organ reduction and abdominal wall closure were not amenable, patients underwent a traction-assisted abdominal wall closure applying fasciotens®Pediatric. Outcome parameters were time to closure, surgical complications, infections, and hernia formation. RESULTS: Ten patients with GOC and 6 patients with GS were included. Complete fascial closure was achieved after a median time of 7 days (range 4-22) in GOC and 5 days (range 4-11) in GS. There were two cases of tear-outs of traction sutures and one skin suture line dehiscence after fascial closure. No surgical site infection or signs of abdominal compartment syndrome were seen. No ventral or umbilical hernia occurred after a median follow-up of 12 months (range 4-22). CONCLUSION: Traction-assisted staged closure using fasciotens®Pediatric enabled an early tension-less fascial closure in GOC and GS in the newborn period.

Management of Gastroschisis: Timing of Delivery, Antibiotic Usage, and Closure Considerations (A Systematic Review From the American Pediatric Surgical Association Outcomes & Evidence Based Practice Committee).

BACKGROUND: No consensus exists for the initial management of infants with gastroschisis. METHODS: The American Pediatric Surgical Association (APSA) Outcomes and Evidenced-based Practice Committee (OEBPC) developed three a priori questions about gastroschisis for a qualitative systematic review. We reviewed English-language publications between January 1, 1970, and December 31, 2019. This project describes the findings of a systematic review of the three questions regarding: 1) optimal delivery timing, 2) antibiotic use, and 3) closure considerations. RESULTS: 1339 articles were screened for eligibility; 92 manuscripts were selected and reviewed. The included studies had a Level of Evidence that ranged from 2 to 4 and recommendation Grades B-D. Twenty-eight addressed optimal timing of delivery, 5 pertained to antibiotic use, and 59 discussed closure considerations (Figure 1). Delivery after 37 weeks post-conceptual age is considered optimal. Prophylactic antibiotics covering skin flora are adequate to reduce infection risk until definitive closure. Studies support primary fascial repair, without staged silo reduction, when abdominal domain and hemodynamics permit. A sutureless repair is safe, effective, and does not delay feeding or extend length of stay. Sedation and intubation are not routinely required for a sutureless closure. CONCLUSIONS: Despite the large number of studies addressing the above-mentioned facets of gastroschisis management, the data quality is poor. A wide variation in gastroschisis management was documented, indicating a need for high quality RCTs to provide an evidence-based approach when caring for these infants. TYPE OF STUDY: Qualitative systematic review of Level 1-4 studies.

Factors of poor prognosis in newborns with a prenatal diagnosis of gastroschisis in Bogota, Colombia.

OBJECTIVES: To identify factors associated with poor prognoses in newborns with a prenatal diagnosis of gastroschisis in eight hospitals in Bogota, Colombia, from 2011 to 2022. METHODS: A multi-center retrospective case-control study was conducted on newborns with gastroschisis in eight hospitals in Bogota, Colombia. Poor prognosis was defined as the presence of sepsis, intestinal complications, or death. RESULTS: The study included 101 patients. Preterm newborns under 32 weeks had a poor neonatal prognosis (OR 6.78 95 % CI 0.75-319). Oligohydramnios (OR 4.95 95 % CI 1.15-21.32) and staged closure with silo (OR 3.48; 95 % CI 1.10-10.96) were risk factors for neonatal death, and intra-abdominal bowel dilation of 20-25 mm was a factor for the development of intestinal complications (OR 3.22 95 % CI 1.26-8.23). CONCLUSIONS: Intra-abdominal bowel dilation between 20 and 25 mm was associated with intestinal complications, while oligohydramnios was associated with the risk of perinatal death, requiring increased antenatal surveillance of fetal wellbeing. Management with primary reduction when technically feasible is recommended in these infants, considering that the use of silos was associated with higher mortality.

County-Level Atrazine Use and Gastroschisis.

Importance: The incidence of gastroschisis, a birth defect involving the herniation of the small bowel through the abdominal wall, has increased in the US since the 1960s. The pesticide atrazine is a hypothesized cause of gastroschisis; however, examination of the association between atrazine and gastroschisis has been limited. Objective: To evaluate national trends in gastroschisis incidence, maternal and infant characteristics associated with gastroschisis, and whether county-level atrazine use is associated with gastroschisis. Design, Setting, and Participants: This retrospective, repeated cross-sectional study examined birth certificate data of all live births in the US and data on atrazine use from the US Geological Survey from January 1, 2009, through December 31, 2019. The data analysis was performed between August 5, 2021, and May 26, 2023. Exposures: County-level atrazine use. Main Outcomes and Measures: The primary outcome was gastroschisis incidence. Covariates included maternal age, race and ethnicity, body mass index (measured by weight in kilograms divided by height in meters squared), parity, insurance type, Chlamydia infection during pregnancy, smoking, and rurality. Mixed-effects logistic regression models (year fixed effects and county random effects) were constructed using different county-level atrazine exposure variables (1-, 5-, and 10-year means). Results: Between 2009 and 2019, 39 282 566 live births were identified, with 10 527 infant diagnoses of gastroschisis. Infants with gastroschisis were more likely to have mothers who identified as non-Hispanic White (61% vs 54%; P < .001), had a lower body mass index (median [IQR], 23.4 [20.8-27.2] vs 25.4 [22.0-30.8]; P < .001), were more likely to be nulliparous (median [IQR], 0 [0-1] vs 1 [0-2]; P < .001), and were more commonly covered by Medicaid (63% vs 43%; P < .001). During the study period, the rate (per 1000 live births) of gastroschisis decreased from 0.31 (95% CI, 0.29-0.33) to 0.22 (95% CI, 0.21-0.24). The median (IQR) county-level atrazine use estimates were higher among infants with gastroschisis (1 year, 1389 [IQR, 198-10 162] vs 1023 [IQR, 167-6960] kg; 5 years, 1425 [IQR, 273-9895] vs 1057 [IQR, 199-6926] kg; 10 years, 1508 [IQR, 286-10 271] vs 1113 [IQR, 200-6650] kg; P < .001). In adjusted models, higher county levels of atrazine (each 100 000-kg increase) were associated with a higher incidence of gastroschisis (1 year: adjusted odds ratio [AOR], 1.12 [95% CI, 1.01-1.24]; 5 years: AOR, 1.15 [95% CI, 1.02-1.30]; 10 years: AOR, 1.21 [95% CI, 1.07-1.38]). Conclusions and Relevance: In this cross-sectional study, higher county levels of atrazine were associated with infant diagnoses of gastroschisis. While atrazine is the second-most used herbicide in the US, numerous countries around the world have banned it out of concern for adverse effects on human health. These findings suggest that exploring alternatives to atrazine in the US may be warranted.

Chest radiographic thoracic areas and respiratory outcomes in infants with anterior abdominal wall defects.

OBJECTIVES: Infants with anterior abdominal wall defects (AWD) can suffer from pulmonary complications. Our aims were to determine if the chest radiographic thoracic areas (CRTAs) on day one differed between infants with exomphalos or gastroschisis, whether this related to differing severity of outcomes and if they were lower than those of controls indicating abnormal antenatal lung growth. METHODS: A review of infants with exomphalos or gastroschisis born between January 2004 and January 2023 was conducted. The control group was term, newborn infants ventilated for poor respiratory drive at birth. Chest radiographs on day one were analysed and the highest CRTA in the first 24 h after birth for each infant included in the analysis. RESULTS: The 127 infants with gastroschisis had a lower gestational age and birthweight than the 62 exomphalos infants and 130 controls (all p<0.001) The CRTAs of the controls were greater than the CRTAs of the exomphalos and the gastroschisis infants (p = 0.001). The median CRTA corrected for birthweight was lower in the exomphalos infants [688, IQR 568-875 mm2/kg] than the gastroschisis infants [813, IQE 695-915 mm2/kg] No gastroschisis infant developed bronchopulmonary dysplasia (BPD). A CRTA of 1759 mm2 had a sensitivity of 81 % and specificity of 71 % in predicting BPD in infants with exomphalos. CONCLUSIONS: Infants with gastroschisis or exomphalos had lower CRTAs than controls suggesting both groups had abnormal antenatal lung development. The CRTA was lower in the exomphalos infants who also had worse respiratory outcomes, hence CRTA assessment may a useful prognostic aid.

Gastroschisis: embriology, pathogenesis, risk factors, prognosis, and ultrasonographic markers for adverse neonatal outcomes.

Gastroschisis is the most common congenital defect of the abdominal wall, typically located to the right of the umbilical cord, through which the intestinal loops and viscera exit without being covered by the amniotic membrane. Despite the known risk factors for gastroschisis, there is no consensus on the cause of this malformation. Prenatal ultrasound is useful for diagnosis, prognostic prediction (ultrasonographic markers) and appropriate monitoring of fetal vitality. Survival rate of children with gastroschisis is more than 95% in developed countries; however, complex gastroschisis requires multiple neonatal interventions and is associated with adverse perinatal outcomes. In this article, we conducted a narrative review including embryology, pathogenesis, risk factors, and ultrasonographic markers for adverse neonatal outcomes in fetuses with gastroschisis. Prenatal risk stratification of gastroschisis helps to better counsel parents, predict complications, and prepare the multidisciplinary team to intervene appropriately and improve postnatal outcomes.

Prenatal cannabis use disorder and gastroschisis in California, 2007-19.

BACKGROUND: Gastroschisis is a congenital anomaly of the abdominal wall with an unknown aetiology. Recent trends in the prevalence of gastroschisis suggest that changing environmental or behavioural factors may contribute. We examined whether prenatal cannabis use disorder was associated with gastroschisis. METHODS: The Study of Outcomes of Mothers and Infants is a population-based cohort compiled of California birth records that have been linked to Department of Health Care Access and Information hospitalization, emergency department and ambulatory surgery records. We included 2007-19 singleton live births (n = 5 774 656). Cannabis use disorder was measured by diagnosis codes at any visit during pregnancy or at birth. Gastroschisis was measured by diagnosis or surgical repair procedure codes at birth or during the first year of life. RESULTS: The prevalence of cannabis use disorder was about 1%. The prevalence of gastroschisis was 0.14% and 0.06% among those with and without cannabis use disorder, respectively. There were positive associations between cannabis use disorder and gastroschisis when using a multivariable model [adjusted risk ratio (aRR) = 1.3, 95% confidence interval (CI) 1.0, 1.7) and a matched sample approach (aRR = 1.5, 95% CI 1.1, 2.1). The association varied by maternal age and was largest among people aged >34 years (aRR = 2.5, 95% CI 1.0, 5.8). CONCLUSIONS: We confirm findings of a positive association between cannabis exposure and gastroschisis and add that it is strongest when maternal age is greater than 34 years. More investigation into whether the association is causal, and why the association varies by maternal age, is encouraged.

The Association of Prenatal Diagnoses with Mortality and Long-Term Morbidity in Children with Specific Isolated Congenital Anomalies: A European Register-Based Cohort Study.

OBJECTIVES: To compare 5-year survival rate and morbidity in children with spina bifida, transposition of great arteries (TGA), congenital diaphragmatic hernia (CDH) or gastroschisis diagnosed prenatally with those diagnosed postnatally. METHODS: Population-based registers' data were linked to hospital and mortality databases. RESULTS: Children whose anomaly was diagnosed prenatally (n = 1088) had a lower mean gestational age than those diagnosed postnatally (n = 1698) ranging from 8 days for CDH to 4 days for TGA. Children with CDH had the highest infant mortality rate with a significant difference (p < 0.001) between those prenatally (359/1,000 births) and postnatally (116/1,000) diagnosed. For all four anomalies, the median length of hospital stay was significantly greater in children with a prenatal diagnosis than those postnatally diagnosed. Children with prenatally diagnosed spina bifida (79% vs 60%; p = 0.002) were more likely to have surgery in the first week of life, with an indication that this also occurred in children with CDH (79% vs 69%; p = 0.06). CONCLUSIONS: Our findings do not show improved outcomes for prenatally diagnosed infants. For conditions where prenatal diagnoses were associated with greater mortality and morbidity, the findings might be attributed to increased detection of more severe anomalies. The increased mortality and morbidity in those diagnosed prenatally may be related to the lower mean gestational age (GA) at birth, leading to insufficient surfactant for respiratory effort. This is especially important for these four groups of children as they have to undergo anaesthesia and surgery shortly after birth. Appropriate prenatal counselling about the time and mode of delivery is needed.

Risk Factors for Infection in Neonates With Intestinal Failure.

PURPOSE: Neonates with intestinal failure (IF) are at risk for infection due to central venous access, and intestinal surgery. Infection can cause systemic inflammation and sepsis, potentially affecting growth. The purpose of this study was to identify risk factors for, and the potential impact of infection to help with preventative strategies. METHODS: A retrospective review of infants with IF, at a single centre from 2018 to 2022 was conducted. Clinical characteristics, intestinal pathology, nutritional intake, and growth were compared among infants with bloodstream infection (BSI), other infection (OI) (urinary, respiratory, or wound), or no infection (NI) within 2 months of diagnosis. Mann-Whitney and Kruskal-Wallis tests were used for comparisons with p-values <0.05 considered significant. RESULTS: Eighty-six infants were included, with gastroschisis (41%) and necrotizing enterocolitis (26%) the most common diagnoses. Fifty-nine % of infants developed infection (22% BSI and 37% OI). Those with BSI or OI had a lower gestational age and birthweight, and were more likely to have a stoma. All infants with complex gastroschisis developed infection compared to 38% of infants with simple gastroschisis. Median daily weight gain was suboptimal across all groups and did not differ over 6 weeks following infection. CONCLUSION: Most infants with IF develop infection shortly after diagnosis. Risk factors include prematurity, complex gastroschisis, and the presence of a stoma. Growth was suboptimal but did not differ among infants with or without infection. TYPE OF STUDY: Retrospective Review. LEVEL OF EVIDENCE: Level III Retrospective Comparative Study.

Gastroschisis prevalence patterns in 27 surveillance programs from 24 countries, International Clearinghouse for Birth Defects Surveillance and Research, 1980-2017.

BACKGROUND: Gastroschisis is a serious birth defect with midgut prolapse into the amniotic cavity. The objectives of this study were to evaluate the prevalence and time trends of gastroschisis among programs in the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR), focusing on regional variations and maternal age changes in the population. METHODS: We analyzed data on births from 1980 to 2017 from 27 ICBDSR member programs, representing 24 countries and three regions (Europe+ (includes Iran) , Latin America, North America). Cases were identified using diagnostic codes (i.e., 756.7, 756.71, or Q79.3). We excluded cases of amniotic band syndrome, limb-body wall defect, and ruptured omphalocele. Programs provided annual counts for gastroschisis cases (live births, stillbirths, and legally permitted pregnancy terminations for fetal anomalies) and source population (live births, stillbirths), by maternal age. RESULTS: Overall, gastroschisis occurred in 1 of every 3268 births (3.06 per 10,000 births; 95% confidence intervals [CI]: 3.01, 3.11), with marked regional variation. European+ prevalence was 1.49 (95%CI: 1.44, 1.55), Latin American 3.80 (95%CI: 3.69, 3.92) and North American 4.32 (95%CI: 4.22, 4.42). A statistically significant increasing time trend was observed among six European+ , four Latin American, and four North American programs. Women <20 years of age had the highest prevalence in all programs except the Slovak Republic. CONCLUSIONS: Gastroschisis prevalence increased over time in 61% of participating programs, and the highest increase in prevalence was observed among the youngest women. Additional inquiry will help to assess the impact of the changing maternal age proportions in the birth population on gastroschisis prevalence.

Association of Exclusive Breast Milk Intake and Outcomes in Infants With Uncomplicated Gastroschisis: A National Cohort Study.

BACKGROUND: Enteral feeding is an essential part of the management of infants with gastroschisis. We hypothesized that exclusive breast milk is associated with improved neonatal outcomes. METHODS: We conducted a retrospective review of infants with uncomplicated gastroschisis through the Canadian Pediatric Surgery Network (CAPSNet) and Canadian Neonatal Network (CNN). The primary outcome was time to full enteral feeds. RESULTS: We identified 411 infants with gastroschisis treated at CAPSNet centres from 2014 to 2022. 144 patients were excluded due to gestational age <32 weeks, birth weight <1500 g, other congenital anomalies, or complicated gastroschisis. Of the remaining 267 participants, 78% (n = 209) received exclusive breast milk diet in the first 28 days of life, whereas 22% (n = 58) received supplemental or exclusive formula. Infants who received exclusive breast milk experienced higher time to reach full enteral feeding (median 24 vs 22 days, p = 0.047) but were more likely to have undergone delayed abdominal closure (32% vs 17%, p = 0.03). After adjustment, there were no significant differences between groups in time to reach full enteral feeds, duration of parenteral nutrition, or length of stay. Infants who received supplemental or exclusive formula had a similar risk of necrotizing enterocolitis (4% vs 3%) but were less likely to transition to exclusive breast milk at discharge (73% vs 11%, p < 0.001). CONCLUSION: Early use of exclusive breast milk in infants with uncomplicated gastroschisis is associated with similar outcomes compared to supplemental or exclusive formula. Patients who received supplemental or exclusive formula were unlikely to transition to exclusive breastfeeding by discharge. LEVEL OF EVIDENCE: Level IIb (Individual Cohort Study).

European reference network for rare inherited congenital anomalies (ERNICA) evidence based guideline on the management of gastroschisis.

BACKGROUND: The European Reference Network for rare Inherited Congenital Anomalies, ERNICA, guidelines for gastroschisis cover perinatal period to help teams to improve care. METHOD: A systematic literature search including 136 publications was conducted. Research findings were assessed following the GRADE methodology. The evidence to decision framework was used to determine the strength and direction of recommendations. RESULTS: The mode or timing of delivery do not impact neonatal mortality, risk of NEC or time on parenteral nutrition (PN). Intra or extra abdominal bowel dilatation predict complex gastroschisis and longer length of hospital stay but not increased perinatal mortality. Outcomes after Bianchi procedure and primary fascia closure under anesthesia are similar. Sutureless closure decreases the rate of surgical site infections and duration of ventilation compared to surgical closure. Silo-staged closure with or without intubation results in similar outcomes. Outcomes of complex gastroschisis (CG) undergoing early or delayed surgical repair are similar. Early enteral feeds starting within 14 days is associated with lower risk of surgical site infection. RECOMMENDATIONS: The panel suggests vaginal birth between 37 and 39 w in cases of uncomplicated gastroschisis. Bianchi's approach is an option in simple gastroschisis. Sutureless closure is suggested when general anesthesia can be avoided, sutured closure. If anesthesia is required. Silo treatment without ventilation and general anesthesia can be considered. In CG with atresia primary intestinal repair can be attempted if the condition of patient and intestine allows. Enteral feeds for simple gastroschisis should start within 14 days.

[Gastroschisis and omphalocele: Incidence and outcome].

INTRODUCTION: Gastroschisis and omphalocele are the most common congenital abdominal wall defects. The main purpose of this study was to investigate the incidence, other associated anomalies and the course of these diseases in Iceland. MATERIAL AND METHODS: The study was retrospective. The population was all newborns who were admitted to the NICU of Children's Hospital Iceland due to gastroschisis or omphalocele in 1991-2020. Furthermore, all fetuses diagnosed prenatally or post mortem where the pregnancy ended in spontaneous or induced abortion, were included. RESULTS: During the study period, 54 infants were born with gastroschisis and five with omphalocele. The incidence of gastroschisis was 4.11 and omphalocele 0,38/10,000 births. There was no significant change in the incidence of the diseases during the study period. In addition, five fetuses were diagnosed with gastroschisis and 31 with omphalocele where the pregnancy was terminated. In addition to gastroschisis in the live born infants and fetuses the most common associated anomalies were in the gastrointestinal or urinary tract but in infants and fetuses with omphalocele anomalies of the cardiac, central nervous or skeletal systems were the most common. Sixteen fetuses diagnosed with omphalocele had trisomy 18. Mothers aged 16-20 were more likely to give birth to an infant with gastroschisis than older mothers (p< 0.001). Primary closure was successful in 86% of the infants. Those reached full feedings significantly earlier and were discharged earlier. Overall survival rate was 95%. Three children were still receiving parenteral nutrition at discharge due to short bowel syndrome. CONCLUSIONS: The incidence of gastroschisis in Iceland is in accordance with studies in other countries but but the incidence of omphalocele is lower, which can be partly explained by spontaneous or induced abortions. Other anomalies associated with omphalocele are more severe than those associated with gastroschisis. Primary closure was associated with more benign course. Children with gastroschisis may need prolonged parenteral nutrition due to shortening of their intestines.

Public health priorities for gastroschisis: Summary of a meeting sponsored by the Centers for Disease Control and Prevention and the March of Dimes.

BACKGROUND: Gastroschisis has increased worldwide over several decades; however, there are significant gaps in understanding risk factors for development of the defect, particularly those that might be modifiable. Despite advances in survival, little is known about longer-term outcomes for affected individuals. METHODS: On April 27- and 28, 2023, the National Center on Birth Defects and Developmental Disabilities at the Centers for Disease Control and Prevention (CDC) and March of Dimes sponsored a meeting entitled "Public Health Priorities for Gastroschisis". The meeting goals were to review current knowledge on gastroschisis, discuss research gaps, and identify future priorities for public health surveillance, research, and action related to gastroschisis. Meeting participants encompassed a broad range of expertise and experience, including public health, clinical care of individuals with gastroschisis, affected individuals and families, and representatives from professional organizations and federal agencies. RESULTS: Several goals were identified for future public health surveillance and research, including focused theory-driven research on risk factors and increased study of longer-term effects of gastroschisis through improved surveillance. Certain public health actions were identified, that which could improve the care of affected individuals, including increased education of providers and enhanced resources for patients and families. CONCLUSIONS: These efforts may lead to an improved understanding of pathogenesis, risk factors, and outcomes and to improved care throughout the lifespan.

Temporal Trends of Neonatal Surgical Conditions in Texas and Accessibility to Pediatric Surgical Care.

INTRODUCTION: Texas consistently accounts for approximately 10% of annual national births, the second highest of all US states. This temporal study aimed to evaluate incidences of neonatal surgical conditions across Texas and to delineate regional pediatric surgeon accessibility. METHODS: The Texas Birth Defects Registry was queried from 1999 to 2018, based on 11 well-established regions. Nine disorders (30,476 patients) were identified as being within the operative scope of pediatric surgeons: biliary atresia (BA), pyloric stenosis (PS), Hirschsprung's disease, stenosis/atresia of large intestine/rectum/anus, stenosis/atresia of small intestine, tracheoesophageal fistula/esophageal atresia, gastroschisis, omphalocele, and congenital diaphragmatic hernia. Annual and regional incidences were compared (/10,000 births). Statewide pediatric surgeons were identified through the American Pediatric Surgical Association directory. Regional incidences of neonatal disorder per surgeon were evaluated from 2010 to 2018 as a surrogate for provider disparity. RESULTS: PS demonstrated the highest incidence (14.405/10,000), while BA had the lowest (0.707/10,000). Overall, incidences of PS and BA decreased significantly, while incidences of Hirschsprung's disease and small intestine increased. Other diagnoses remained stable. Regions 2 (48.24/10,000) and 11 (47.79/10,000) had the highest incidence of neonatal conditions; Region 6 had the lowest (34.68/10,000). Three rural regions (#2, 4, 9) lacked pediatric surgeons from 2010 to 2018. Of regions with at least one surgeon, historically underserved regions (#10, 11) along the Texas-Mexico border consistently had the highest defect per surgeon rates. CONCLUSIONS: There are temporal and regional differences in incidences of neonatal conditions treated by pediatric surgeons across Texas. Improving access to neonatal care is a complex issue that necessitates collaborative efforts between state legislatures, health systems, and providers.

National population-based estimates for major birth defects, 2016-2020.

BACKGROUND: We provide updated crude and adjusted prevalence estimates of major birth defects in the United States for the period 2016-2020. METHODS: Data were collected from 13 US population-based surveillance programs that used active or a combination of active and passive case ascertainment methods to collect all birth outcomes. These data were used to calculate pooled prevalence estimates and national prevalence estimates adjusted for maternal race/ethnicity for all conditions, and maternal age for trisomies and gastroschisis. Prevalence was compared to previously published national estimates from 1999 to 2014. RESULTS: Adjusted national prevalence estimates per 10,000 live births ranged from 0.63 for common truncus to 18.65 for clubfoot. Temporal changes were observed for several birth defects, including increases in the prevalence of atrioventricular septal defect, tetralogy of Fallot, omphalocele, trisomy 18, and trisomy 21 (Down syndrome) and decreases in the prevalence of anencephaly, common truncus, transposition of the great arteries, and cleft lip with and without cleft palate. CONCLUSION: This study provides updated national estimates of selected major birth defects in the United States. These data can be used for continued temporal monitoring of birth defects prevalence. Increases and decreases in prevalence since 1999 observed in this study warrant further investigation.

Medication use during pregnancy and the risk of gastroschisis: a systematic review and meta-analysis of observational studies.

OBJECTIVES: The aetiology of gastroschisis is considered multifactorial. We conducted a systematic review and meta-analysis to assess whether the use of medications during pregnancy, is associated with the risk of gastroschisis in offspring. METHODS: PubMed, EMBASE, and Scopus were searched from 1st January 1990 to 31st December 2020 to identify observational studies examining the association between medication use during pregnancy and the risk of gastroschisis. The Newcastle-Ottawa Scale was used for the quality assessment of the individual studies. We pooled adjusted measures using a random-effect model to estimate relative risk [RR] and the 95% confidence interval [CI]. I2 statistic for heterogeneity and publication bias was calculated. RESULTS: Eighteen studies providing data on 751,954 pregnancies were included in the meta-analysis. Pooled RRs showed significant associations between aspirin (RR 1.66, 95% CI 1.16-2.38; I2 = 58.3%), oral contraceptives (RR 1.52, 95% CI 1.21-1.92; I2 = 22.0%), pseudoephedrine and phenylpropanolamine (RR 1.51, 95% CI 1.16-1.97; I2 = 33.2%), ibuprofen (RR 1.42, 95% CI 1.26-1.60; I2 = 0.0%), and gastroschisis. No association was observed between paracetamol and gastroschisis (RR 1.16, 95% CI 0.96-1.41; I2 = 39.4%). CONCLUSIONS: These results suggest that the exposure in the first trimester of pregnancy to over the counter medications (OTC) such as aspirin, ibuprofen, pseudoephedrine and phenylpropanolamine as well as to oral contraceptives, was associated with an increased risk of gastroschisis. However, these associations are significant only in particular subgroups defined by geographic location, adjustment variables and type of control. Therefore, further research is needed to investigate them as potential risk factors for gastroschisis, to assess their safety in pregnancy and to develop treatment strategies to reduce the risk of gastroschisis in offspring. PROSPERO registration number: CRD42021287529.

Trends in Attempted Vaginal Delivery among Pregnancies Complicated by Gastroschisis, 2014 to 2020.

OBJECTIVE: Gastroschisis is a full-thickness congenital defect of the abdominal wall through which intestines and other organs may herniate. In a prior analysis, attempted vaginal delivery with fetal gastroschisis appeared to increase through 2013, although cesarean delivery remained common. The objective of this analysis was to update current trends in attempted vaginal birth among pregnancies complicated by gastroschisis. STUDY DESIGN: We performed an updated cross-sectional analysis of live births from 2014 and 2020 using data from the U.S. National Vital Statistics System and evaluated trends in attempted vaginal deliveries among births with gastroschisis. Trends were evaluated using joinpoint regression. We constructed logistic regression models to evaluate the association between demographic and clinical variables and attempted vaginal delivery in the setting of gastroschisis. RESULTS: Among 5,355 deliveries with gastroschisis meeting inclusion criteria, attempted vaginal delivery increased significantly from 68.9% to 75.1%, an average annual percent change of 1.7% (95% confidence interval [CI], 0.8-2.5). Among gastroschisis-complicated pregnancies, patients 35 to 39 years old (adjusted odds ratio [aOR], 0.53; 95% CI, 0.37-0.79) and Hispanic race/ethnicity (aOR, 0.69; 95% CI, 0.58-0.62) were at lower likelihood of attempted vaginal delivery in adjusted analyses. CONCLUSION: These findings suggest that vaginal delivery continues to increase in the setting of gastroschisis. Further reduction of surgical delivery for this fetal defect may be possible. KEY POINTS: · Vaginal deliveries increased among gastroschisis pregnancies.. · Hispanic patients were less likely to attempt vaginal delivery.. · Some gastroschisis pregnancies still deliver surgically..
