Abstract
PURPOSE Urological management of Cloacal Malformation (CM) focuses on preserving renal function and continence. Study aim was to analyze urinary and intestinal outcomes in CM patients, considering the length of common channel (CC) and presence of occult spinal dysraphism (OSD). METHODS Retrospective review of CM treated at our institution by a multidisciplinary team from 1999 to 2020. Patients with follow-up < 2.5 years were excluded. Length of CC, renal function, urinary and bowel outcomes, presence of associated anomalies (especially OSD) were evaluated. RESULTS Twenty patients were included, median age at follow-up: 8 years (4-15). A long CC > 3 cm was described in 11 (55%). Chronic kidney disease was found in 3 patients. Urinary continence was achieved in 8/20 patients, dryness (with intermittent catheterization) in 9/20. Fecal continence was obtained in 3/20, cleanliness in 14 (under bowel regimen). OSD was present in 10 patients (higher prevalence in long-CC, 73%). Among OSD, 1 patient reached fecal continence, 7 were clean; 2 achieved urinary continence, while 6 were dry. CONCLUSIONS Length of CC and OSD may affect urinary and fecal continence. An early counseling can improve outcome at long-term follow-up. Multidisciplinary management with patient centralization in high grade institutions is recommended to achieve better results.

ENVIRONMENTAL RESEARCH 2023; 229:115937. [PMID: 37076028 PMCID: PMC10198955 DOI: 10.1016/j.envres.2023.115937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 03/30/2023] [Accepted: 04/16/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND Chemicals used or emitted by unconventional oil and gas development (UOGD) include reproductive/developmental toxicants. Associations between UOGD and certain birth defects were reported in a few studies, with none conducted in Ohio, which experienced a thirty-fold increase in natural gas production between 2010 and 2020. METHODS We conducted a registry-based cohort study of 965,236 live births in Ohio from 2010 to 2017. Birth defects were identified in 4653 individuals using state birth records and a state surveillance system. We assigned UOGD exposure based on maternal residential proximity at birth to active UOG wells and a metric specific to the drinking-water exposure pathway that identified UOG wells hydrologically connected to a residence ("upgradient UOG wells"). We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for all structural birth defects combined and specific birth defect types using binary exposure metrics (presence/absence of any UOG well and presence/absence of an upgradient UOG well within 10 km), adjusting for confounders. Additionally, we conducted analyses stratified by urbanicity, infant sex, and social vulnerability. RESULTS The odds of any structural defect were 1.13 times higher in children born to mothers living within 10 km of UOGD than those born to unexposed mothers (95%CI: 0.98-1.30). Odds were elevated for neural tube defects (OR: 1.57, 95%CI: 1.12-2.19), limb reduction defects (OR: 1.99, 95%CI: 1.18-3.35), and spina bifida (OR 1.93; 95%CI 1.25-2.98). Hypospadias (males only) was inversely related to UOGD exposure (OR: 0.62, 95%CI: 0.43-0.91). Odds of any structural defect were greater in magnitude but less precise in analyses using the hydrological-specific metric (OR: 1.30; 95%CI: 0.85-1.90), in areas with high social vulnerability (OR: 1.27, 95%CI: 0.99-1.60), and among female offspring (OR: 1.28, 95%CI: 1.06-1.53). CONCLUSIONS Our results suggest a positive association between UOGD and certain birth defects, and findings for neural tube defects corroborate results from prior studies.

Abstract
Spina bifida (SB) remains the most serious and most common congenital anomaly of the human nervous system that is compatible with life. The open myelomeningocele on the back is perhaps the most obvious initial problem, but the collective impact of dysraphism upon the entirety of the nervous system and innervated organs is an equal or greater longitudinal threat. As such, patients with myelomeningocele (MMC) are best managed in a multi-disciplinary clinic that brings together experienced medical, nursing, and therapy teams that provide high standards of care while studying outcomes and sharing insights and experiences. Since its inception 30 years ago, the spina bifida program at UAB/Children's of Alabama has remained dedicated to providing exemplary multi-disciplinary care for affected children and their families. During this time, there has been great change in the care landscape, but many of the neurosurgical principles and primary issues have remained the same. In utero myelomeningocele closure (IUMC) has revolutionized initial care and has favorable impact on several important co-morbidities of SB including hydrocephalus, the Chiari II malformation, and the functional level of the neurologic deficit. Hydrocephalus however is not solved by IUMC, and hydrocephalus management remains at the center of neurosurgical care in SB. Ventricular shunts were long the cornerstone of treatment for hydrocephalus, but we came to assess and incorporate endoscopic third ventriculostomy with choroid plexus coagulation (ETV-CPC). Educated and nurtured by an experienced senior mentor, we dedicated ourselves to fundamental concepts but persistently evaluated our care outcomes and evolved our protocols and paradigms for improvement. Active conversations amidst networks of treasured colleagues were central to this development and growth. While hydrocephalus support and treatment of tethered spinal cord remained our principal neurosurgical charges, we evolved to embrace a holistic perspective and approach that is reflected and captured in the Lifetime Care Plan. Our team engaged actively in important workshops and guideline initiatives and was central to the development and support of the National Spina Bifida Patient Registry. We started and developed an adult SB clinic to support our patients who aged out of pediatric care. Lessons there taught us the importance of a model of transition that emphasized personal responsibility and awareness of health and the crucial role of dedicated support over time. Support for sleep, bowel health, and personal intimate cares are important contributors to overall health and care. This paper details our growth, learning, and evolution of care provision over the past 30 years.

Abstract
OBJECTIVES This study aimed to verify possible associations between sociodemographic and clinical factors in live births with spinal dysraphism. METHODS An analytical (descriptive and inferential) and ecological study was carried out based on secondary data of 11,308 live births with spinal dysraphism registered in the Live Birth Information System (SINASC) in Brazil from 1999 to 2019. Demographic factors analyzed were age, education, mothers' marital status and geographic region. The clinical factors analyzed were duration, gestation period, birthweight, and number of prenatal visits performed by women who underwent medical follow-up. RESULTS There was an increase in the number of cases of spinal dysraphism in recent years in Brazil with an annual percentage variation of 3.52%. However, the period from 2005 to 2009 showed a reduction in live births with spinal dysraphism. The regions with the highest incidence were the South and Southeast. The risk increased in mothers born after 1980, older than 30 years and with a high level of education. The risk was increased in live births of whites and blacks, born from double pregnancy and with body weight less than 3000 g. The absence of prenatal care was associated with a higher incidence. CONCLUSION Sociodemographic and clinical factors have specific characteristics that can predict spinal dysraphism in newborns in Brazil.

Abstract
Spinal dysraphism, most commonly myelomeningocele, is the typical cause of a neurogenic lower urinary tract dysfunction (NLUTD) in childhood. The structural changes in the bladder wall in spinal dysraphism already occur in the fetal period and affect all bladder wall compartments. The progressive decrease in smooth muscle and the gradual increase in fibrosis in the detrusor, the impairment of the barrier function of the urothelium, and the global decrease in nerve density, lead to severe functional impairment characterized by reduced compliance and increased elastic modulus. Children present a particular challenge, as their diseases and capabilities evolve with age. An increased understanding of the signaling pathways involved in lower urinary tract development and function could also fill an important knowledge gap at the interface between basic science and clinical implications, leading to new opportunities for prenatal screening, diagnosis, and therapy. In this review, we aim to summarize the evidence on structural, functional, and molecular changes in the NLUTD bladder in children with spinal dysraphism and discuss possible strategies for improved management and for the development of new therapeutic approaches for affected children.

Abstract
OBJECTIVE To determine the efficacy of three different maternal screening programs (first-trimester screening [FTS], individual second-trimester screening [ISTS], and first- and second-trimester combined screening [FSTCS]) in predicting offspring with trisomy 21, trisomy 18, and neural tube defects (NTDs). METHODS A retrospective cohort involving 108,118 pregnant women who received prenatal screening tests during the first (9-13+6 weeks) and second trimester (15-20+6 weeks) in Hangzhou, China from January-December 2019, as follows: FTS, 72,096; ISTS, 36,022; and FSTCS, 67,631 gravidas. RESULT The high and intermediate risk positivity rates for trisomy 21 screening with FSTCS (2.40% and 5.57%) were lower than ISTS (9.02% and 16.14%) and FTS (2.71% and 7.19%); there were statistically significant differences in the positivity rates among the screening programs (all P < 0.05). Detection of trisomy 21 was as follows: ISTS, 68.75%; FSTCS, 63.64%; and FTS, 48.57%. Detection of trisomy 18 was as follows; FTS and FSTCS, 66.67%; and ISTS, 60.00%. There were no statistical differences in the detection rates for trisomy 21 and 18 among the 3 screening programs (all P > 0.05). The positive predictive values (PPVs) for trisomy 21 and 18 were highest with FTS, while the false positive rate (FPR) was lowest with FSTCS. CONCLUSION FSTCS was superior to FTS and ISTS screening and substantially reduced the number of high risk pregnancies for trisomy 21 and 18; however, FSTCS was not significantly different in detecting fetal trisomy 21 and 18 and other confirmed cases with chromosomal abnormalities.

Abstract
Micturition requires complex interplay involving bladder, peripheral neural network, spinal cord, and brain. Spinal dysraphism presents variety of neural lesions that may affect this interplay leading to neurogenic bladder. However, the diagnosis of neurogenic bladder in those with spinal dysraphism is often difficult and contrasted to other types of neurogenic bladder caused by complete neural lesions such as spinal cord injury or brain tumor. Typically, neurogenic bladder caused by spinal dysraphism shows lower motor neuron lesion and partial neural injury. However, upper motor signs can be seen with the occurrence of tethered cord syndrome and developmental immaturity of bladder control often complicated by fecal impaction. Thus, the diagnosis of tethered cord syndrome should be made cautiously. Several invasive and noninvasive diagnostic modalities could be applied for accurate diagnosis, preventing renal damage and controlling urinary incontinence. However, it should be borne in mind that no single study is definitive for accurate diagnosis, so it requires careful scrutiny in interpretation. The follow-up scheme of these patients should be determined to detect urological deterioration due to the development of tethered cord syndrome. Since the development of tethered cord syndrome shows diverse nature implicating urological and orthopedic issues, multidisciplinary collaboration is essential for comprehensive care.

Abstract
Whether it is for collaboration on folic acid fortification or the standardization of care efforts concerning neurogenic bowel dysfunction, a global forum on neural tube defects related issues is needed. Propitiously, the 2023 Spina Bifida World Congress sponsored by the Spina Bifida Association (SBA) was a catalyst for transnational dialog in the field of spina bifida (SB) research. Concurrently, the Journal of Pediatric Rehabilitation Medicine (JPRM) provides a platform for both international research as well as numerous clinical and educational projects, such as The Lifespan Bowel Management Protocol, and social interventions taught through the American Academy of Pediatrics' Spina Bifida Transition ECHO. Through this open access issue, work by colleagues in Ethiopia, the Nordic countries, and Switzerland, as well as among other transnational populations is highlighted. The development of the Spina Bifida Global Learning Collaborative is also showcased, representing a training initiative across four continents. Correspondingly in this issue, JPRM published an update to the Transition Guidelines for the Care of People with Spina Bifida. The clinical guidelines are a product of the SBA Collaborative Care Network cooperative agreement with the National Center on Birth Defects and Developmental Disabilities in the Centers for Disease Control and Prevention. While colleagues across the globe remain committed to native, immigrant, and displaced populations of individuals affected by SB, JPRM will continue to distribute premier research in multidisciplinary care, education, and advocacy.

Abstract
Spinal dysraphism is a group of disorders resulting from an embryologic failure of spinal cord development which can lead to a radicular-medullary mechanical stretch that generates vascular compromise and hypoxic-ischemic damage to the nervous structures of the conus-cauda region.Thus, the clinical relevance of the different types of spinal dysraphism is related to the possible neurologic deficits resulting from spinal cord tethering. The clinical presentation is heterogenous: from asymptomatic to very compromised patients. The indications and the time of a detethering surgery are still subject of debate, although there is an agreement on the high standards of treatment that have to be offered by the surgery. Intraoperative neurophysiology (ION) contributes to the safety of tethered cord surgery in reducing the risks of iatrogenic neurological damages.

Abstract
Introduction. Of the many congenital anomalies (CAs) recently linked with community cannabis exposure, arguably the most concerning are neurological CAs (NCAs). We therefore conducted a detailed study of this in fourteen European nations. Methods. Congenital anomaly data were from Eurocat. Drug exposure data were from European Monitoring Centre for Drugs and Drug Addiction. Income from World bank. Results. The Netherlands, Spain, France and Bulgaria reported increasing rates of many NCAs. The NCA rate (NCAR) was higher in nations with increasing daily cannabis use when compared to those without (p = 0.0204, minimum E-value (mEV) = 1.35). At bivariate analysis, the mEVs of the following NCAs were significantly cannabis related: severe microcephaly 2.14 × 1013, craniosynostosis 5.27 × 1011, nervous system 4.87 × 1011, eye 2.73 × 107, microphthalmos 4.07 × 106, anencephalus 710.37, hydrocephalus 245.64, spina bifida 14.86 and neural tube defects 13.15. At inverse probability, weighted panel regression terms including cannabis were significantly related to the following series of anomalies: nervous system, anencephalus, severe microcephalus, microphthalmos, neural tube defect and spina bifida from p = 5.09 × 10−8, <2.2 × 10−16, <2.2 × 10−16, 4.84 × 10−11, <2.2 × 10−16 and 9.69 × 10−7. At geospatial regression, this same series of anomalies had terms including cannabis significant from p = 0.0027, 1.53 × 10−7, 3.65 × 10−6, 2.13 × 10−8, 0.0002 and 9.76 × 10−12. 88.0% of 50 E-value estimates and 72.0% of mEVs > 9. This analysis therefore demonstrates both close association of cannabis exposure with multiple NCAs across space-time and also fulfills the quantitative criteria of causal inferential analysis. Conclusions. Nine NCARs on bivariate and six NCARs on multivariable regression were cannabis related and fulfilled quantitative epidemiological criteria for causality and are consistent with other series. Particular concerns relate to exponential dose−response effects demonstrated in the laboratory and epidemiological studies. Great caution with community cannabinoid penetration is warranted. Data indicate that cannabis is a significant environmental teratogen and thus imply that cannabinoids should be regulated similarly to the manner in which all other important genotoxins are carefully controlled by communities for their self-sustaining longevity and the protection of generations yet to come.

Abstract
We studied associations between prenatal and early postnatal choline intake, brain development, and neurocognitive function of children. We conducted a systematic review followed by a meta-analysis and critical appraisal of human studies published from 1997 to 2021. Thirty publications were identified. The meta-analysis included 5 of 7 case-control studies studying neural tube defects (NTDs) in relation to maternal choline intakes/circulating concentrations. Low maternal choline intake/circulating concentrations were associated with a higher OR for NTDs among 1131 mothers of newborns with NTDs and 4439 control mothers (pooled estimate = 1.36; 95% CI: 1.11, 1.67). The 95% prediction intervals were 0.78, 2.36. Findings and critical evaluation of 10 publications with interventional designs showed that higher maternal choline intakes during the second half of pregnancy and early postnatal period (550 mg up to 1 g/d on top of the diet) or a child intake of 513 to 625 mg/d from supplements were safe and likely to demonstrate favorable effects on several domains of child neurocognition, such as memory, attention, and visuospatial learning versus the comparators. Findings from observational studies (n = 13) partly supported the association between maternal choline intake/serum concentrations and child neurocognition, but there was low confidence in the use of plasma choline concentrations as a choline intake marker. In conclusion, low maternal choline intakes were associated with a higher OR for NTDs. The risk could be up to 2.36-fold in some populations. Despite limitations of available trials and observational studies, higher maternal choline intake was likely to be associated with better child neurocognition/neurodevelopment. The results should be used to guide choline intake recommendations in pregnancy and lactation, especially because most young women are not achieving the reference intake of choline. This meta-analysis is registered at PROSPERO as CRD42021233790.

Abstract
Mandatory fortification of food with synthetic folic acid (FA) was instituted in 1998 to reduce the incidence of neural tube defects. Adequate folate status is correlated with numerous health benefits. However, elevated consumption of FA is controversially associated with deleterious effects on health. We previously reported that excess FA mimicked folate depletion in a lymphoblastoid cell line. To explore the impact of FA intake from fortified food, we conducted an observational human study on 33 healthy participants aged 18-40 not taking any supplements. Food intake, anthropomorphic measurements, and blood samples were collected and analyzed. Our results show that individuals belonging to the highest tertile of folic acid intake, as well as ones with the highest folic acid to total folate intake ratio (FAR), display a significantly greater incidence of lymphocyte genomic damage. A decrease in global DNA methylation is observed in the highest tertile of FAR compared to the lowest (p = 0.055). A downward trend in the overall gene expression of select DNA repair and one carbon cycle genes (MGMT, MLH1, UNG, MTHFR, MTR) is noted with increased folate status and FA intake. These results provide supporting evidence that high consumption of FA from fortified foods can precipitate genomic instability in peripheral lymphocyte in vivo.

Abstract
BACKGROUND Neural tube defect (NTD) is a multifactorial disorder. Decrease transfer of folate to the developing embryo is one of the etiologies. It could be due to decrease folate receptors resulting in NTD in fetus. OBJECTIVE To analyze serum folate receptor alpha (FOLR1) concentration in women having fetus with NTD and compare it with women having normal fetus during and after pregnancy. MATERIAL AND METHODS This was a prospective case control study conducted in a tertiary care hospital. Pregnant women with detected isolated NTD in fetus were enrolled as cases and equal number of matched pregnant women without any fetal congenital malformation were recruited as controls. Serum FOLR1 levels were analyzed in cases and controls during pregnancy and 6 weeks after delivery. RESULTS Mean serum FOLR1 concentration during pregnancy was 70.5 pg/mL (range: 23.8-98.5 pg/mL) and 103.9 pg/mL (range: 70-110 pg/mL) in cases and controls, respectively. Serum level of FOLR1 was 448.9 pg/mL (range: 133.5-475) and 414.5 pg/mL (range: 269.7-412.5) in cases and controls at 6 weeks postpartum, respectively. There was statistically significant difference (P < 0.001) between cases and control during pregnancy but not in postpartum (P = 0.092). There was significant increase in level of FOLR1 in both cases and control at 6 weeks postpartum as compared to antenatal period. CONCLUSIONS Maternal serum FOLR1 is significantly reduced in pregnancy with fetal NTD as compared to normal pregnancy. The level is significantly increased in postpartum period in both groups. FOLR1 level being similar in both groups in postpartum indicates that it is not influenced by the history of fetal NTD.

Abstract
OBJECTIVE Encephalocele is a rare congenital neural tube defect (NTD) characterized by herniation of intracranial contents through a defect in the skull. In our study, encephalocele was diagnosed in our clinic and its association with hydrocephalus was evaluated. The effect of this association on the prognosis was discussed. PATIENTS AND METHODS Patients who underwent surgery and follow-up with the diagnosis of encephalocele in the neurosurgery clinic of our hospital in an 8-year period from 2013 to 2021 were retrospectively examined. RESULTS Patient records were obtained from the case notes of patients who underwent excision and repair for encephalocele. Of the 78 patients included in the study, 88.4% underwent surgery in the neonatal period. Moreover, 47% of the patients are male, and 31% are female. Encephalocele was present in 62.8% of patients and meningocele in 37.2%. Furthermore, 82.1% of encephalocele sacs were located in the occipital region. Chiari type 3 malformation was present in 57.6% of patients. Hydrocephalus developed in 56.4% of patients. There was an additional syndrome in 10.3% of the cases. The most common additional syndromes were corpus callosum dysgenesis with 39.7% and colpocephaly with 29.5%. The additional disease was present in 43.6% of patients. Preoperative and postoperative examination findings of more than half of patients were normal, but 33.3% were apathetic. Furthermore, 67.9% of patients, who underwent complete repair, survived, and 32.1% died. Hydrocephalus was present in 73.5% of patients with encephalocele (p<0.05). Hydrocephalus developed in 77.8% of patients with Chiari type 3 malformation (p<0.05). Hydrocephalus was found in 88.0% of patients with Ex (p<0.05). CONCLUSIONS Encephalocele, which is a subgroup of NTD, differs clinically by its location and accompanying additional anomalies. In encephaloceles, the risk of morbidity and mortality can only be reduced with the multidisciplinary approach. Hydrocephalus and Chiari type 3 malformation are common in patients with encephalocele. These associations adversely affect the prognosis of the disease. Further research should be conducted on the evaluation of risk factors of NTD and methods of prevention from NTD. In this regard, we recommend that the training be repeated at certain intervals and that people's awareness should be raised.

Abstract
Various types of progenitors initiate individual organ formation and their crosstalk orchestrates morphogenesis for the entire embryo. Here we show that progenitor exosomal communication across embryonic organs occurs in normal development and is altered in embryos of diabetic pregnancy. Endoderm fibroblast growth factor 2 (FGF2) stimulates mesoderm Flk-1+ vascular progenitors to produce exosomes containing the anti-stress protein Survivin. These exosomes act on neural stem cells of the neuroepithelium to facilitate neurulation by inhibiting cellular stress and apoptosis. Maternal diabetes causes Flk-1+ progenitor dysfunction by suppressing FGF2 through DNA hypermethylation. Restoring endoderm FGF2 prevents diabetes-induced survivin reduction in Flk-1+ progenitor exosomes. Transgenic Survivin expression in Flk-1+ progenitors or in utero delivery of survivin-enriched exosomes restores cellular homeostasis and prevents diabetes-induced neural tube defects (NTDs), whereas inhibiting exosome production induces NTDs. Thus, functional inter-organ communication via Flk-1 exosomes is vital for neurulation and its disruption leads to embryonic anomalies.
