Folic Acid-Fortified Iodized Salt and Serum Folate Levels in Reproductive-Aged Women of Rural India: A Nonrandomized Controlled Trial.

Importance: India has a disproportionately high prevalence of neural tube defects, including spina bifida and anencephaly (SBA), causing a high number of stillbirths, elective pregnancy terminations, and child mortality; India contributes a large proportion of the global burden of SBA. Thirty years after folic acid was shown to be effective in reducing SBA prevalence, only about one-quarter of such births are prevented globally through cereal grain fortification. Objective: To determine the association of folic acid-fortified iodized salt with serum folate concentrations among nonpregnant and nonlactating women of reproductive age. Design, Setting, and Participants: This nonrandomized controlled trial using a preintervention and postintervention design was conducted in 4 rural villages in Southern India from July 1 to November 30, 2022. All households in the villages agreed to participate in the study. Preintervention and postintervention serum folate levels were analyzed among study participants at baseline and after 4 months, respectively. Intervention: Consumption of approximately 300 µg/d of folic acid using double fortified salt (folic acid plus iodine). Median serum folate concentrations were assessed at baseline and 4 months. Main Outcomes and Measures: Change in median serum folate levels between baseline and study end point as the primary outcome of the study. Results: A total of 83 nonpregnant nonlactating women aged 20 to 44 years (mean [SD] age, 30.9 [5.1] years) were eligible for the study and provided serum samples for analysis at baseline and the end point of the intervention. The median serum folate concentration increased from 14.6 (IQR, 11.2-20.6) nmol/L at baseline to 54.4 (IQR, 43.5-54.4) nmol/L at end of study, a 3.7-fold increase from baseline to study end point. Two-tailed Wilcoxon signed rank test showed the median difference in preintervention and postintervention serum folate concentrations to be highly significant (P < .001). The participants found the salt acceptable in color and taste. Conclusions and Relevance: Use of folic acid-fortified iodized salt was associated with increased serum folate concentrations in women of reproductive age. This novel evidence can inform public health policy to accelerate SBA prevention. Trial Registration: ClinicalTrials.gov Identifier: NCT06174883.

Prevalence of neural tube defects in England prior to the mandatory fortification of non-wholemeal wheat flour with folic acid: a population-based cohort study.

OBJECTIVES: To determine the baseline trends in the total birth prevalence of neural tube defects (NTDs) in England (2000-2019) to enable the impact of folic acid fortification of non-wholemeal wheat flour to be monitored. DESIGN: Population-based, observational study using congenital anomaly (CA) registration data for England curated by the National Congenital Anomaly and Rare Disease Registration Service (NCARDRS). SETTING: Regions of England with active registration in the time period. PARTICIPANTS: Babies that were liveborn or stillborn and pregnancies that resulted in a termination of pregnancy or a late miscarriage (20-23 weeks' gestation) with an NTD. MAIN OUTCOME MEASURES: Total birth prevalence of anencephaly, spina bifida and all NTDs in England. Poisson regression analysis was used to evaluate time trends with regional register as a random effect. The progress of national registration across England was assessed. RESULTS: There were 4541 NTD pregnancies out of 3 637 842 births in England; 1982 anencephaly and 2127 spina bifida. NTD prevalence was 12.5 (95% CI 12.1 to 12.9) per 10 000 total births. NTD prevalence per 10 000 total births was significantly higher in 2015-2019 (13.6, 95% CI 12.9 to 14.4) compared with 2010-2014 (12.1, 95% CI 11.7 to 12.5). An increasing trend in NTDs overall was detected (incidence rate ratio (IRR) 1.01, 1.00 to 1.02), although further analysis determined this effect was confined to 2015-2019 (compared against 2000-2004, IRR 1.14, 1.04 to 1.24). The birth prevalence of anencephaly reflected this pattern. The prevalence of spina bifida remained relatively stable over time. CONCLUSIONS: Baseline NTD prevalence for England has been established. National and standardised CA registration is in place, facilitating the systematic and consistent monitoring of pre-fortification and post-fortification NTD trends and evaluating the impact of fortification on NTD prevalence.

Thalamic connectivity topography in newborns with spina bifida: association with neurological functional level but not developmental outcome at 2 years.

Spina bifida affects spinal cord and cerebral development, leading to motor and cognitive delay. We investigated whether there are associations between thalamocortical connectivity topography, neurological function, and developmental outcomes in open spina bifida. Diffusion tensor MRI was used to assess thalamocortical connectivity in 44 newborns with open spina bifida who underwent prenatal surgical repair. We quantified the volume of clusters formed based on the strongest probabilistic connectivity to the frontal, parietal, and temporal cortex. Developmental outcomes were assessed using the Bayley III Scales, while the functional level of the lesion was assessed by neurological examination at 2 years of age. Higher functional level was associated with smaller thalamo-parietal, while lower functional level was associated with smaller thalamo-temporal connectivity clusters (Bonferroni-corrected P < 0.05). Lower functional levels were associated with weaker thalamic temporal connectivity, particularly in the ventrolateral and ventral anterior nuclei. No associations were found between thalamocortical connectivity and developmental outcomes. Our findings suggest that altered thalamocortical circuitry development in open spina bifida may contribute to impaired lower extremity function, impacting motor function and independent ambulation. We hypothesize that the neurologic function might not merely be caused by the spinal cord lesion, but further impacted by the disruption of cerebral neuronal circuitry.

Bias analyses to investigate the impact of differential participation: Application to a birth defects case-control study.

BACKGROUND: Certain associations observed in the National Birth Defects Prevention Study (NBDPS) contrasted with other research or were from areas with mixed findings, including no decrease in odds of spina bifida with periconceptional folic acid supplementation, moderately increased cleft palate odds with ondansetron use and reduced hypospadias odds with maternal smoking. OBJECTIVES: To investigate the plausibility and extent of differential participation to produce effect estimates observed in NBDPS. METHODS: We searched the literature for factors related to these exposures and participation and conducted deterministic quantitative bias analyses. We estimated case-control participation and expected exposure prevalence based on internal and external reports, respectively. For the folic acid-spina bifida and ondansetron-cleft palate analyses, we hypothesized the true odds ratio (OR) based on prior studies and quantified the degree of exposure over- (or under-) representation to produce the crude OR (cOR) in NBDPS. For the smoking-hypospadias analysis, we estimated the extent of selection bias needed to nullify the association as well as the maximum potential harmful OR. RESULTS: Under our assumptions (participation, exposure prevalence, true OR), there was overrepresentation of folic acid use and underrepresentation of ondansetron use and smoking among participants. Folic acid-exposed spina bifida cases would need to have been ≥1.2× more likely to participate than exposed controls to yield the observed null cOR. Ondansetron-exposed cleft palate cases would need to have been 1.6× more likely to participate than exposed controls if the true OR is null. Smoking-exposed hypospadias cases would need to have been ≥1.2 times less likely to participate than exposed controls for the association to falsely appear protective (upper bound of selection bias adjusted smoking-hypospadias OR = 2.02). CONCLUSIONS: Differential participation could partly explain certain associations observed in NBDPS, but questions remain about why. Potential impacts of other systematic errors (e.g. exposure misclassification) could be informed by additional research.

Successful sacral neuromodulation treatment of refractory faecal incontinence in a patient with spina bifida and partial sacral agenesis.

A woman in her early 20s with a history of lumbosacral lipomyelomeningocele with associated partial sacral agenesis and tethered cord was referred for possible sacral neuromodulation treatment of her refractory faecal incontinence. Anorectal testing revealed a thinned and weakened anal sphincter complex with absent left-sided bulbocavernosus and anal wink reflexes.Through a two-stage approach, she underwent successful placement of a chronic tined quadripolar sacral nerve lead and implanted pulse generator. Despite significant distortion of normal bony anatomic landmarks, bilateral S3 and S4 foraminal entry was possible, with intraoperative motor and sensory testing providing key confirmation of appropriate lead placement. The patient had a substantial improvement in her baseline frequency and urgency with a near-complete resolution of faecal incontinence episodes during her test phase.

What has changed in pediatric neurosurgical care in spina bifida? A 30-year UAB/Children's of Alabama observational overview.

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.

Multi-Institutional Review From the Pediatric Colorectal and Pelvic Learning Consortium of Minor Spinal Cord Dysraphism in the Setting of Anorectal Malformations: Diagnosis, Treatment, and Outcomes.

BACKGROUND/RATIONALE: Anorectal malformations (ARM) are associated with congenital anomalies of the spine, but the impact of a minor spinal cord dysraphism (mSCD) on fecal continence in the setting of ARM remains unclear. MATERIALS/METHODS: A retrospective review was performed utilizing data from the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) registry. The patient cohort was reviewed for ARM type, mSCD screening/incidence/neurosurgical intervention and age-based BMP utilization. RESULTS: 987 patients with ARM were categorized into mild (38%), moderate (32%) or complex (19%). 694 (70%) had normal spinal (NS) status. 271 (27.5%) patients had mSCD. MRI alone (49%) was the most common screening test for mSCD. US screening had a positive predictive value of 86.3% and a negative predictive value of 67.1%. Surgical intervention rates for mSCD ranged between 13% and 77% at a median age of 0.6-5.2 years. 726 (73.6%) patients were prescribed BMP (74.4% NS, 77.5% mSCD). Laxatives were most utilized BMP in all groups <5yo. ≥5yo, enema utilization increased with ARM complexity independent of spine status (with or without neurosurgical intervention). Neurosurgical intervention did not affect BMP utilization at any age or with any ARM when mSCD was identified. CONCLUSIONS: MSCD influence on bowel function in the setting ARM remains unclear. No significant impact of mSCD was noted on ARM patient bowel management program utilization. Variability exists within PCPLC site with screening and intervention for mSCD in patients with ARM. Future studies with standardized care may be needed to elucidate the true impact of mSCD on long term patient outcomes in ARM patients. TYPE OF STUDY: Retrospective Comparative Study. LEVEL OF EVIDENCE: III.

Understanding factors influencing primary treatment with intradetrusor onabotulinumtoxinA versus augmentation cystoplasty in patients with spina bifida.

PURPOSE: Surgical interventions in the urologic management of children with neurogenic bladder secondary to spina bifida aim to preserve upper tract function, prevent urinary tract infections, and optimize quality of life. However, since the introduction of intravesical onabotulinumtoxinA (Botox) in the management of these patients, the indications for choosing Botox over augmentation cystoplasty (AC) remain undefined. The objective of this study was to determine which factors lead patients to undergo Botox versus AC as a primary surgical treatment after failing medical management. METHODS: We retrospectively reviewed the records of pediatric patients with myelomeningocele undergoing either primary Botox or primary AC at our institution between 2013 and 2018. We recorded demographic and clinical information. We identified 10 important clinical decision-making factors: bladder trabeculation, vesicoureteral reflux, or hydronephrosis on imaging; end-filling pressure (EFP) ≥40 cm H2O, detrusor overactivity, detrusor-sphincter dyssynergia, or reduced capacity on urodynamic studies; physician-perceived bladder hostility; and patient/family desire for continence and independence. The presence of these factors was compared between patients undergoing either primary Botox or primary AC. RESULTS: We identified 14 and 50 myelomeningocele patients who underwent primary AC and primary Botox, respectively. We found no significant differences in age, sex, race, or history of reconstructive surgery (antegrade continence enema or catheterizable channel). For the 10 decision-making factors, desire for independence/continence (p = <0.001) and reduced capacity (p = 0.002) were significantly associated with AC, while trabeculation (p = 0.006), EFP ≥40 cm H2O (p = 0.029), rising slope (p = 0.019), and physician-perceived hostility (p = 0.012) were significantly more common with Botox. CONCLUSIONS: At our institution, quality of life measures prompted AC over objective urodynamic or imaging findings before attempting Botox. These findings support a shared decision-making approach when considering surgical intervention for neurogenic bladder secondary to myelomeningocele.

Transitioning care for adolescents with spina bifida in the US: challenges for management.

Open spina bifida (OSB) is a common neural tube defect. Medical and surgical care involves addressing the baseline orthopedic, urologic, and neurological dysfunction as well as the changes or declines that may occur as the patient ages. Given the complexity of this disease, coordinated, multidisciplinary care involving specialists in neurosurgery, orthopedics, urology, rehabilitation and physical medicine, pediatrics, and psychology is necessary to establish and optimize baseline function. Traditionally in the US, pediatric multispecialty spina bifida clinics have provided the patient with a coordinated medical support system. Unfortunately, this coordinated, medical home has been difficult to establish during the transition from pediatric to adult care. Medical professionals must have a strong understanding of OSB to properly manage the disease and detect and prevent associated complications. In this manuscript, we (1) describe the changing needs and challenges of people living with OSB over a lifespan, (2) delineate current practices in the transition of care for people with OSB from childhood to adulthood, and (3) provide recommendations for best practices in navigating the transition process for clinicians who provide care for those afflicted with this most complex congenital abnormality of the nervous system compatible with long term survival.

Neural tube defects: Prevalence, mortality, and maternal characteristics in two departmental hospitals in the northwestern region of Nicaragua, 2006-2018.

BACKGROUND: Congenital anomalies are the fifth most common cause of neonatal mortality in Nicaragua, and neural tube defects (NTDs) are the most common of all cases of lethality associated with a birth defect. Prevalence and mortality estimates are needed to propose effective intervention strategies that prevent NTDs over time. METHODS: A cross-sectional study was carried out in northwestern Nicaragua from January 2006 to December 2018. All cases of NTDs (anencephaly, spina bifida, and encephalocele) were registered in hospital surveillance systems, and the medical histories of the mothers and newborns were reviewed. Prevalence was calculated by considering the number of live births and stillbirths older than 20 weeks of gestation with NTDs, divided by the total number of live births and stillbirths in each study year. Neonatal mortality rate (NMR) for NTD, and case fatality for spina bifida was calculated. RESULTS: Two hundred fifty cases of NTDs were identified from 178,498 deliveries (177,316 live births and 1,182 stillbirths). The prevalence of NTDs during this time period was 14.01 (95% CI: 12.27-15.74) per 10,000 births. The prevalence of spina bifida (n = 140), anencephaly (n = 97), and encephalocele (n = 13) was 7.84, (95% CI: 6.54-9.14), 5.43 (95% CI: 4.30-6.45), and 0.73 (95% CI: 0.33-1.12) per 10,000 births, respectively. Mothers with fetus or newborns affected with NTDs did not use folic acid prior to conception, and 11% experienced periods of hyperthermia during the first trimester of pregnancy. NMR for NTDs was 0.55 per 1.000 livebirths. Case fatality for all NTDs and for spina bifida were 55% and 18%, respectively. CONCLUSION: The prevalence and mortality of NTDs in the northwestern region of Nicaragua present peaks and troughs during the study period. Spina bifida was the most frequent type of NTD. We believe that these findings could be of use by health policy makers to strengthen the primary prevention of NTDs in the region through the monitoring of the food fortification policy and folic acid supplementation to women of childbearing age. Additional etiologic studies of NTDs should be considered to identify additional prevention measures.

People with spina bifida use their MACE on long-term follow-up: A single institutional retrospective cohort study.

OBJECTIVE: While the Malone antegrade continence enema (MACE) facilitates bowel movements in patients with spina bifida (SB) and neuropathic bowel, little is known about its long-term use. We aimed to assess long-term MACE use and potential risk factors for disuse. METHODS: All patients with SB who underwent MACE procedures at our institution were retrospectively reviewed. Main outcome was MACE disuse (no longer catheterizing the MACE for antegrade enemas) based on self-report on a clinic questionnaire, or medical record for patients last seen before introducing the questionnaire 5 years ago. Survival analysis used two timeframes: time after surgery (Analysis 1) and chronological age: accounting for older children reaching adulthood earlier (Analysis 2). RESULTS: Overall, 411 patients (54% female, 78% shunted, 65% augmented) underwent a MACE procedure at median 7.9 years old (median follow-up: 8.4 years). Thirty-three (8%) patients no longer used their MACE. Most common reasons for doing so were channel/stomal stenosis (61%) and excision at colostomy or other abdominal surgery (12%). Bowel management afterwards included oral agents ± enemas (55%), Chait tube (30%), colostomy (12%). After correcting for differential follow-up, 90% of participants used their MACE at 10 years and 87% at 15 years after surgery. Based on chronological age, 97% used their MACE at 15 years old, 92% at 20 and 81% at 30 (Summary Figure). On multivariate analysis, umbilical MACEs were 2.4 times more likely to be disused than right lower quadrant MACEs (p = 0.04). Without correcting for chronological age (Analysis 1), patients undergoing MACE surgery at older ages were more likely to stop MACE use (p = 0.03). However, after accounting for chronological age (Analysis 2), patients undergoing a MACE procedure at older ages were no more likely to stop its use (p = 0.47, Figure). Gender, SB type, shunt status, mobility status, bladder augmentation or a urinary catheterizable channel were not associated with stopping MACE use (p ≥ 0.10). COMMENT: Participants were regularly followed in multi-disciplinary SB clinics. We did not assess continence, satisfaction or long-term urinary channel use, making it premature to recommend optimal stomal locations. CONCLUSIONS: Most patients with SB followed by a multi-disciplinary team continue using their MACE; 1% stopped MACE use annually, particularly after adolescence. This strongly suggests it is an effective bowel management method and transitioning to self-care plays a role in maintaining long-term MACE use. Umbilical MACEs may be at high risk of disuse, but all people with a MACE can benefit from support as they transition to adult care.

A case study of ReachAnother Foundation as a change champion for developing spina bifida neurosurgical care and advocating for primary prevention in Ethiopia.

Spina bifida is a serious birth defect affecting the central nervous system, characterized by incomplete closure of the neural tube. Ethiopia has a very high prevalence of spina bifida, affecting about 40 cases per 10,000 births. Babies born with spina bifida require early closure surgery, done within the first 2-3 days after birth. Some babies need repeat surgeries to address complications, including hydrocephalus. Without medical care, babies have a high risk of death within the first 5 years of their life. Neurosurgical capacity for spina bifida closure surgery at birth is a relatively new development in Ethiopia. ReachAnother Foundation, a not-for-profit organization based in OR, USA, started work in Ethiopia in 2009 and has been instrumental in training neurosurgeons and improving treatment for spina bifida and hydrocephalus. Along with the development of neurosurgical care, the Foundation has invested in training multi-disciplinary teams to conduct patient aftercare and has launched a platform for improved patient outcomes research. As of year 2022, they support six spina bifida "Centers of Excellence" nationwide and are continuously advocating for primary prevention of spina bifida through mandatory fortification of staple foods in Ethiopia. This paper describes ReachAnother's efforts in Ethiopia in a short interval of time, benefiting numerous patients and families with spina bifida and anencephaly. We document this as a case study for other countries to model where resources are limited and the prevalence of spina bifida and hydrocephalus is high, especially in Asia and Africa.

Transanal irrigation to manage neurogenic bowel in the pediatric population with spina bifida: a scoping review.

OBJECTIVE: To map available scientific evidence about the pediatric population with spina bifida submitted to transanal irrigation to manage signs and symptoms of neurogenic bowel. SOURCE OF DATA: This research was developed according to recommendations from the Joanna Briggs Institute Reviewers' Manual and the PRISMA Extension for Scoping Reviews. Searches were carried out in the databases: CINAHL, Medline/Pubmed, Scielo, Scopus, Web of Science, Embase, LILACS, Proquest, and the CAPES catalog of theses and dissertations. Quantitative and qualitative studies on the topic were included, as long as they dealt with this population. There was no predetermined time frame. SUMMARY OF THE FINDINGS: The authors found 1.020 studies, selected 130 for close reading, and included 23 in the review, all of which had been published from 1989 to 2021. The authors mapped the characteristics of the studies, including their definitions of concepts and use of scales, criteria for the indication of transanal irrigation, training to carry out the procedure, devices and solutions used, number and frequency of transanal irrigations, health care actions, time spent, associated complications, complementary exams, adherence rate, follow-up, and outcomes, focusing on the benefits for bowel management. CONCLUSIONS: Despite the variability of evaluation parameters and term definitions, evidence suggests that transanal irrigation is a safe and effective method to manage fecal incontinence. Studies in the field are likely to grow, using standardized scales and longitudinal follow-ups. The authors suggest further research on transanal irrigation in the pediatric population with spina bifida in the Latin American context.

Prevented cases of neural tube defects and cost savings after folic acid fortification of flour in Brazil.

Anencephaly, encephalocele, and spina bifida are congenital neural tube defects and are the main causes of neonatal morbidity and mortality and impose a heavy economic burden on health systems. This study to estimates the direct costs of neural tube defects from the perspective of the Brazilian Ministry of Health, and the prevented cases and cost savings during the period in which mandatory folic acid fortification was in effect in the country (2010-2019). It is a top-down cost-of-illness oriented study based on the prevalence of the disorders in Brazil. Data were collected from the Brazilian Ministry of Health's outpatient and hospital information system databases. The direct cost was estimated from the total patient-years, allocated by age and type of disorder. Prevented cases and cost savings were determined by the difference in the prevalence of the disorders in the pre- and post-fortification periods based on the total number of births and the sum of outpatient and hospital costs during the period. The total cost of outpatient and hospital services for these disorders totaled R$ 92,530,810.63 (Int$ 40,565,896.81) in 10 years; spina bifida accounted for 84.92% of the total cost. Hospital costs were expressive of all three disorders in the first year of the patient's life. Between 2010 and 2019, mandatory folic acid fortification prevented 3,499 live births with neural tube defects and resulted in R$ 20,381,586.40 (Int$ 8,935,373.25) in hospital and outpatient cost savings. Flour fortification has proved to be a valuable strategy in preventing pregnancies with neural tube defects. Since its implementation, there has been a 30% decrease in the prevalence of neural tube defects and a 22.81% decrease associated in hospital and outpatient costs.

Spina bifida folate fortification in Brazil, update 2022: a cross-sectional study.

INTRODUCTION: Despite improving maternal-child indicators in Brazil, congenital malformations are still the second cause of mortality in the first years of life. This work aims to compare statistical data before and after flour fortification with folic acid (FA) in Brazil. METHODS: A cross-sectional Brazilian-population-based study compares the spina bifida (SB) rates pre- and post-fortification of the flour with folate. Data collected from the public database of the Live Birth Information System (SINASC/SUS) was performed. The period 1999-2004 (pre-fortification) was compared with 2005-2010 (post-maize and wheat fortification with FA), and another analysis comparing 2005-2010 and 2011-2020 (cassava flour fortification) was performed. The estimator was the prevalence ratio (PRR); the confidence interval selected was 95%. We used a random effects analysis model and inverse variance. RESULTS: The review showed a tendency to decrease the PRR after flour fortification; however, there is no statistical significance between studies. DATASUS data analysis comparing 5 years before and 5 years after mandatory maize and wheat flour fortification demonstrated a rate ratio of 1.05 (95% CI 0.99-1.1; p = 0.075). Furthermore, comparing 10 years after additional cassava flour folate fortification, the rate ratio increased to 1.4 (95% CI 1.34-1.45; p < 0.01). CONCLUSION: This study demonstrated an increase in SB after FA fortification. Possible explanations rely on national registry improvement, not fortified staple food, or further unidentified causes. Moreover, suggestions can be made for creating a mandatory registry for malformations, inspecting the concentrations of FA in the flour, and fortifying all food.

Correlation of urodynamic studies and somatosensory evoked potential and their prognostic value in children with closed spinal dysraphism.

INTRODUCTION: Somatosensory evoked potential (SSEP) and urodynamic studies (UD) are valuable tools for assessing patients with closed spinal dysraphism (CSD) before neurosurgical intervention. No studies have correlated their findings in this cohort and our aim is to study their correlation and prognostic value in pediatric patients with closed spinal dysraphism. METHODS: Retrospective review of all patients referred to a multidisciplinary clinic in a tertiary pediatric surgical center over a 17 years period between April 2004 to September 2021 was performed. Inclusion criteria were <18 years old, diagnosed with CSD, with SSEP and UD done within 1 year of each other. Demographics data collected include age at presentation/at referral/at neurosurgical operation, gender, symptoms at presentation and intra-operative diagnoses. Pre-operative SSEP and UD findings were documented. Primary outcome was UD results in the group with normal and abnormal SSEP. Secondary outcome was urological and bowel function outcome in 4 groups of patients (Group A-both normal SSEP and UD, Group B- abnormal SSEP only, Group C - abnormal UD only and Group D-both abnormal SSEP and UD). RESULTS: A total of 45 patients were included for analysis. Mean follow up time was 118.9 months (24-216 months, SD 55.8 months). SSEP was normal in 20 patients and abnormal in 25 patients. Baseline demographics, preoperative symptoms and imaging were similar between 2 groups. Primary outcome Patients with abnormal SSEP were more likely to have abnormal UD results with a statistically significant difference (84% vs 40%, p < 0.05). They have a significantly higher end-fill detrusor pressure (12% vs 0%, p < 0.05), abnormal bladder compliance (20% vs 0%, p < 0.05), abnormal cystometric capacity (48% vs 10%, p < 0.05), poor emptying efficiency (24% vs 5%, p < 0.05) and sphincter incompetence (8% vs 0%, p < 0.05). Secondary outcome When compared to Groups A to C, patients in group D were more likely to be on anti-cholinergic (33.3% vs 4.3%, p < 0.05), required clean intermittent catheterization (42.9% vs 4.3%, p < 0.05) and had intravesical botulinum injection (19% vs 0%, p < 0.05). All the patients who had augmentation cystoplasty were in this group as well. Bowel function in terms of regular enema use was also statistically significantly higher in this group (33.4% p < 0.05). CONCLUSION: Pre-operative SSEP and UD results correlate well in patients with closed spinal dysraphism. Patients with abnormal SSEP and UD preoperatively have higher risk of urological deterioration over time. Close monitoring in this group is warranted.

A patient- and parent-centered approach to urinary and fecal incontinence in children and adolescents with spina bifida: understanding experiences in the context of other competing care issues.

INTRODUCTION: Despite significant and known challenges to urinary and fecal incontinence (UI and FI, respectively) among children with spina bifida (SB) and their families, few studies have identified patient-centered measures and approaches to assessing them. This study represents the first stage of a larger study to develop a patient-centered goal-setting tool to guide incontinence management (Figure). Our aim was to understand patient experiences of UI and FI, and what goals should be included in the tool. METHODS: We used a qualitative research approach integrated with human-centered design methods. We recruited, in clinic and online, children with SB (8-17 years old) and parents (>=18 years old) of children with SB (8-17 years old). Online activities were analyzed by four experienced design researchers using affinity diagramming, group analysis and modeling activities (mind maps, challenge maps, experience maps). Recruitment and thematic qualitative analysis continued until saturation was reached. RESULTS: Seventeen children with SB participated (9 female, 12 shunted, 13 using bladder catheterizations, 6 using Malone antegrade continence enema, median age: 15 years old). Fifteen parents participated (13 mothers/2 fathers, median age: 42 years old), including six mother-child dyads. Five major themes each were identified for UI and FI experiences: (1) negative emotional impact of incontinence, (2) unpredictability of incontinence, (3) challenging/unpleasant incontinence management, (4) inconvenient/unreliable incontinence management, (5) UI management having unpleasant complications and FI putting much responsibility on parents. We identified six UI goal domains and five FI goal domains. Four overlapping domains included: accidents, independence, interruptions at school and social/friends. Unique domains were: urinary tract infections (UI), catheterizations (UI) and enemas (FI). COMMENT: Findings of our study improve our understanding of children's and parents' experiences associated with incontinence in SB and potential continence goals. CONCLUSIONS: Children with SB experience incontinence as distressing and unpredictable. Incontinence management can be challenging and unreliable. Patient-centered continence goals cluster in domains, indicating how incontinence intermeshes with other life areas and offering potential approaches to structure continence goals in a goals-selection tool.

The role of neurosurgeons in global public health: the case of folic acid fortification of staple foods to prevent spina bifida.

OBJECTIVE: The global neurosurgery movement arose at the crossroads of unmet neurosurgical needs and public health to address the global burden of neurosurgical disease. The case of folic acid fortification (FAF) of staple foods for the prevention of spina bifida and anencephaly (SBA) represents an example of a new neurosurgical paradigm focused on public health intervention in addition to the treatment of individual cases. The Global Alliance for the Prevention of Spina Bifida-F (GAPSBiF), a multidisciplinary coalition of neurosurgeons, pediatricians, geneticists, epidemiologists, food scientists, and fortification policy experts, was formed to advocate for FAF of staple foods worldwide. This paper serves as a review of the work of GAPSBiF thus far in advocating for universal FAF of commonly consumed staple foods to equitably prevent SBA caused by folic acid insufficiency. METHODS: A narrative review was performed using the PubMed and Google Scholar databases. RESULTS: In this review, the authors describe the impact of SBA on patients, caregivers, and health systems, as well as characterize the multifaceted requirements for proper spina bifida care, including multidisciplinary clinics and the transition of care, while highlighting the role of neurosurgeons. Then they discuss prevention policy approaches, including supplementation, fortification, and hybrid efforts with folic acid. Next, they use the example of FAF of staple foods as a model for neurosurgeons' involvement in global public health through clinical practice, research, education and training, and advocacy. Last, they describe mechanisms for involvement in the above initiatives as a potential academic tenure track, including institutional partnerships, organized neurosurgery, neurosurgical expert groups, nongovernmental organizations, national or international governments, and multidisciplinary coalitions. CONCLUSIONS: The role of neurosurgeons in caring for children with spina bifida extends beyond treating patients in clinical practice and includes research, education and training, and advocacy initiatives to promote context-specific, evidence-based initiatives to public health problems. Promoting and championing FAF serves as an example of the far-reaching, impactful role that neurosurgeons worldwide may play at the intersection of neurosurgery and public health.

The Aperta type of neural tube defect: The relevant experience in a local community with the diversity of the presentation.

A series of birth defects known as neural tube defects (NTDs) appear when the neural tube fails to fully or partially close during fetal development. In nations without folic acid supplementation, their incidence ranges from 0.5 to 2 per 1,000 births. The purpose of our study is to estimate the prevalence of NTDs and define the workup for newborn infants with an open neural tube in Al-Qadissiyah, Iraq. This 18-year descriptive retrospective analysis included all babies with NTD diagnoses at the Maternity and Child Teaching Hospital in Al-Qadissiyah Governorate, Iraq. Over the research period, 187 cases of NTDs were evaluated. NTDs presented a male predominance and an incidence rate of 9.4 per 1,000 births, with spina bifida (67.9%), encephalocele (24.02%), and anencephaly (8.02%) being the most prevalent defects. The typical gestational age was 36±5, whereas the typical maternal age was 30±5. It should be noted that 29.9% of women did not take folic acid supplements during the first trimester, while one-third of moms did not benefit from medical supervision during pregnancy. In 65.2% of instances, an antenatal diagnosis was made, and cesarean section was the mode of delivery in 87,8% of cases. Other than that, 64.7% of women lived in low socioeconomic conditions, and 67.9% were from rural areas. The relevance of reinforcing and maximizing folic acid measures throughout the periconceptional phase is emphasized by the fact that NTDs require high intensity and advanced care.

A global update on the status of prevention of folic acid-preventable spina bifida and anencephaly in year 2020: 30-Year anniversary of gaining knowledge about folic acid's prevention potential for neural tube defects.

BACKGROUND: Spina bifida and anencephaly are major neural tube defects largely preventable through maternal periconceptional intake of folic acid. We estimated the global proportion of folic acid-preventable spina bifida and anencephaly (FAP SBA) prevented through mandatory folic acid fortification of cereal grains, including wheat flour, maize flour, and rice, at the end of year 2020, a time point marking the 30th anniversary of the publication of landmark British Medical Research Council (MRC) study providing unequivocal knowledge on folic acid's FAP SBA prevention potential. METHODS: The Food Fortification Initiative database was used to identify countries with mandatory fortification policies with folic acid added to cereal grains. We examined the status of FAP SBA prevention assuming mandatory folic acid fortification at 200 mcg/day of folic acid protects against FAP SBA and reduces their prevalence to a minimum achievable rate of 0.5 cases/1000 live births. RESULTS: Our analysis showed that 61,680 FAP SBA cases were prevented in the year 2020 through mandatory folic acid fortification of cereal grains in 58 countries, translating to 22% prevention of total possible FAP SBA prevention globally. Many countries in Africa, Asia, and Europe are yet to implement fortification. In 2020, 30 years after the MRC study was published, 218,270 preventable FAP SBA cases still occurred globally. CONCLUSION: Global prevention efforts for FAP SBA are inadequate even after three decades of knowledge on their prevention. Universal mandatory fortification of staples should be urgently implemented to prevent thousands of FAP SBA and associated elective terminations, stillbirths, and child mortality.
