Objective: To identify predictors for intact motor function (MF) at birth and at 12 months of life in babies with prenatally versus postnatally repaired open spina bifida (OSB). Design: Retrospective cohort study. Setting: Texas Children's Hospital, 2011–2018. Population: Patients who underwent either prenatal or postnatal OSB repair. Methods: Prenatal MF of the lower extremities was evaluated by ultrasound following a metameric distribution at the time of diagnosis (US1), 6 weeks postoperatively (or 6 weeks after initial evaluation in postnatally repaired cases) (US2) and at the last ultrasound before delivery (US3). At birth and at 12 months, MF was assessed clinically. Intact MF (S1) was defined as the observation of plantar flexion of the ankle. Results from logistic regression analysis are expressed as odds ratios (95% confidence intervals, P values). Results: A total of 127 patients were included: 93 with prenatal repair (51 fetoscopic; 42 open hysterotomy repair) and 34 with postnatal repair. In the prenatal repair group, predictors for intact MF at birth and at 12 months included: absence of clubfeet (OR 11.3, 95% CI 3.2–39.1, P < 0.01; OR 10.8 95% CI 2.4–47.6, P < 0.01); intact MF at US1 (OR 19.7, 95% CI 5.0–76.9, P < 0.01; OR 8.7, 95% CI 2.0–38.7, P < 0.01); intact MF at US2 (OR 22, 95% CI 6.5–74.2, P < 0.01; OR 13.5, 95% 3.0–61.4, P < 0.01); intact MF at US3 (OR 13.7, 95% CI 3.4–55.9, P < 0.01; OR 12.6, 95% CI 2.5–64.3, P < 0.01); and having a flat lesion (OR 11.2, 95% CI 2.4–51.1, P < 0.01; OR 4.1, 95% CI 1.1–16.5, P = 0.04). In the postnatal repair group, the only predictor of intact MF at 12 months was having intact MF at birth (OR 15.2, 95% CI 2.0–113.3, P = 0.03). Conclusions: The detection of intact MF in utero from mid‐gestation to delivery predicts intact MF at birth and at 12 months in babies who undergo prenatal OSB repair. Detection of intact motor function in utero predicts intact motor function at birth and at 1 year in fetuses who undergo prenatal OSB repair. Detection of intact motor function in utero predicts intact motor function at birth and at 1 year in fetuses who undergo prenatal OSB repair. [ABSTRACT FROM AUTHOR]

Objectives: (1) To compare brain findings between large and non-large neural tube defect (NTD); (2) to evaluate the impact of large lesion on the surgical parameters; (3) to study any associations between the size of the lesions and brain findings 6 weeks postoperatively and neurological short-term outcomes.Design: Retrospective cohort study.Setting: Texas Children's Hospital, between 2011 and 2018.Population: Patients who underwent prenatal NTD repair.Methods: Large lesion was defined when the lesion's surface was >75th centile of our cohorts' lesions.Main Outcome Measures: Time of referral: ventriculomegaly and anatomical level of the lesion; surgery: duration and need for relaxing incisions. 6 weeks postoperative: hindbrain herniation (HBH) and ventriculomegaly. After delivery: dehiscence, need for hydrocephalus treatment and motor function.Results: A total of 99 patients were included, 25 of whom presented with large lesions. Type of lesion and ventriculomegaly were comparable between individuals with large and non-large lesions. Individuals with large lesions were associated with increased need for relaxing incisions by 5.4 times (95% CI 1.3-23.2, P = 0.02). Six weeks postoperatively, having a large lesion decreased by ten times the likelihood of having a postoperative reversal of HBH (odds ratio = 0.1, 95% CI 0.1-0.4, P < 0.01). At birth, larger lesions increased the risk for repair dehiscence by 6.1 times (95% CI 1.6-22.5, P < 0.01) and the risk of dehiscence or leakage of cerebrospinal fluid at birth by 5.5 times (95% CI 1.6-18.9, P < 0.01).Conclusion: Prenatal repair of patients with large NTD presents a lower proportion of HBH reversal 6 weeks after the surgery, a higher risk of dehiscence and a higher need for postnatal repair.Tweetable Abstract: Evaluation of the size of fetal NTD can predict adverse neurological outcomes after prenatal NTD repair.

Background: Controversy exists regarding the optimal mode of delivery for fetuses with open neural tube defects.Objective: To compare neurological outcomes among infants with open neural tube defects who underwent vaginal compared with caesarean delivery.Search Strategy: Electronic databases MEDLINE, EMBASE, Scopus, and Clinicaltrials.gov were searched from inception to November 2017.Selection Criteria: Eligible studies included observational or randomised studies comparing vaginal and caesarean delivery in pregnancies with fetal open neural tube defects who did not undergo prenatal repair.Data Collection and Analysis: Two reviewers independently reviewed abstracts and full-text articles. Outcomes were compared between vaginal and caesarean delivery and prelabour caesarean versus exposure to labour. The primary outcome was motor-anatomic level difference. Secondary outcomes included shunt requirement, sac disruption, meningitis, and ambulation at 2 years. Meta-analysis was performed and mean difference or odds ratios with 95% CI were calculated.Main Results: Of 201 abstracts identified in the primary search, nine studies (672 women) met the eligibility criteria. Comparing vaginal and caesarean delivery, there was no significant difference in motor-anatomic level difference (mean difference -0.10, 95% CI -0.58 to 0.38; I2  = 57%). The vaginal delivery group was less likely to require a shunt or have sac disruption [odds ratio (OR) 0.37, 95% CI 0.14-0.95 and OR 0.46, 95% CI 0.23-0.90, respectively]. Comparisons by prelabour caesarean versus exposure to labour showed no significant difference in motor-anatomic level difference (OR 1.29, 95% CI 0.63-3.21) or ambulation at 2 years (OR 2.13, 95% CI 0.35-13.12).Conclusion: Caesarean delivery was not associated with improved neurological outcomes among fetuses with open neural tube defects.Tweetable Abstract: Available evidence does not support routine caesarean delivery for fetuses with open neural tube defects.

Objective: This study investigated neurodevelopmental outcomes in preterm neonates with posthemorrhagic hydrocephalus (PHH), focusing on the comparative effectiveness of temporary and permanent CSF diversion strategies., Methods: This multicenter prospective observational cohort study (2012-2021) involved preterm infants diagnosed with PHH who underwent either initial permanent or temporary CSF diversion. Patients were assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III), at 15-30 months and, when possible, at 36-42 months of corrected age. Statistical analyses included univariable and multivariable regression models to examine the associations between BSID-III scores and various treatment and patient factors., Results: Among 106 patients, 15 (14%) underwent initial permanent CSF diversion, while 91 (86%) received temporary diversion. Patients who underwent permanent diversion had lower cognitive scores (58.2 ± 5.7) compared to those temporized (69.0 ± 15.9) (p = 0.01). Temporized patients who later required conversion to permanent diversion demonstrated poorer composite (66.6 ± 18.0 vs 79.9 ± 18.8, p = 0.02), expressive (4.6 ± 3.2 vs 7.0 ± 3.7, p = 0.03), and receptive (4.2 ± 3.3 vs 6.1 ± 3.0, p = 0.04) language scores compared to those weaned from temporary CSF diversion. No significant difference in outcomes was observed between patients temporized with a ventriculosubgaleal shunt versus a ventricular reservoir. Ventricle size at the time of initial CSF diversion was not associated with BSID-III scores. However, univariable analysis showed that a larger ventricle size at the time of conversion to permanent diversion was associated with lower neurodevelopmental scores across all domains. Multivariate analysis, adjusting for intraventricular hemorrhage (IVH) grade, complex chronic conditions, and postmenstrual age, revealed that larger ventricle size at the time of conversion correlated negatively with composite motor (effect size -0.47, CI -0.82 to -0.11, p = 0.01) and fine motor (-0.08, CI -0.15 to -0.01, p = 0.03) scores., Conclusions: This study suggested that the choice between permanent and temporary CSF diversion as initial treatments may affect neurodevelopmental outcomes in preterm neonates with PHH, which are influenced by IVH severity and timing of intervention. The findings support early temporization and avoiding delays to optimize permanent shunting. Monitoring ventricular size closely during this phase is critical, as larger ventricular size at the time of conversion is associated with poorer outcomes. These results highlight the necessity for adapting treatment strategies on the basis of individual patient characteristics, responses, and progress in managing PHH.

Objectives: To report the neurodevelopmental outcomes after a fetoscopic myelomeningocele repair and to compare them with children who had an open hysterotomy repair or a postnatal repair., Study Design: We included 132 infants (prenatal repair, 93 [69 fetoscopic and 24 open hysterotomy]; postnatal repair, 39). Neurodevelopmental outcomes at or beyond 18 months were evaluated by a developmental pediatrician using the Capute scales (Clinical Adaptive Test [CAT]/Clinical Linguistic & Auditory Milestone Scale [CLAMS]) and/or during parental interview using Developmental Profile 3 test. Scores were examined against reference values at each gestational age. A normal score was defined as ≥70%. Neurodevelopmental scores were compared while adjusting for infants' age at the time of testing and the need for hydrocephalus treatment., Results: After a fetoscopic repair, normal CLAMS results were observed in 25 of 33 cases (75.8%) and normal CAT in 23 of 33 (69.7%); the Developmental Profile 3 showed normal social-emotional scores in 60 of 65 (92.3%), normal cognition in 55 of 65 (84.6%), normal communication in 51 of 65 (78.5%), normal adaptive behavior in 48 of 65 (73.8%), normal general development in 39 of 65(60%), and normal physical score in 31 of 65 (47.7%) of the cases. Children who underwent a fetoscopic repair had similar neurodevelopmental outcomes compared with those who had an open fetal surgery repair. There was a significantly higher proportion of children with a normal CLAMS (25/33 [75.8%] vs 12/39 [30.8%], P < .01) and normal CAT (23/33 [69.7%] vs 16/39 [41.0%], P = .04) in the fetoscopic group compared with the postnatal repair group., Conclusions: Children who undergo laparotomy-assisted fetoscopic myelomeningocele repair present with normal neurodevelopmental outcomes in two-thirds of the cases included in this study at ≥ 18 months of age and had similar neurodevelopmental outcomes as those who had an open fetal surgery repair., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest relevant to this article.

Background: Functional defecation disorders (FDD) are a common etiology of refractory chronic constipation (CC). FDD diagnosis (dyssynergic defecation [DD] and inadequate defecatory propulsion [IDP]), requires diagnostic tests including anorectal manometry (ARM) and balloon expulsion test (BET). Biofeedback (BF) is the treatment of choice for DD. The aims of our study were to evaluate: the outcome of BF in a group of constipated patients with defecatory disorders of any etiology; the efficacy of two simple diagnostic tools in predicting BF outcome in the short-term., Methods: One hundred and thirty-one refractory CC patients failing the BET underwent BF therapy. Before BF, all patients underwent the following: ARM. Straining questionnaire. The answers were: "belly muscles"; "anal muscles"; "both"; "Don't know/No answer." Digital rectal examination augmented by abdominal palpation on straining (augmented-DRE). The BF therapist was blinded to ARM, straining questionnaire, and augmented-DRE results., Key Results: Eighty-one patients responded to BF. Gender, age, and IBS-C showed no significant impact on BF response. Both DD and IDP responded equally to BF, while the rate of response in patients with isolated structural pelvic floor abnormalities was lower (p < 0.001). The answer "anal muscles" to straining questionnaire showed a strong association with BF response (p < 0.001). A lack in abdominal contraction and in anal relaxation on augmented-DRE were strongly associated with BF response (p < 0.01). Absence of manual maneuvers to facilitate defecation was associated with BF response (p < 0.001)., Conclusions & Inferences: BF is the therapy of choice for refractory constipation due to FDD of any etiology, inducing both clinical and anorectal physiology improvement in the short term. Comorbid IBS-C did not affect outcome while symptomatic isolated pelvic floor abnormalities appeared refractory to behavior treatment. The straining questionnaire and augmented-DRE outcomes showed a strong correlation with BF response and can be implemented in clinical practice to improve the management of constipated patients by prompting early referral to BF., (© 2024 The Author(s).

It is becoming more broadly accepted that human-based models are needed to better understand the complexities of the human nervous system and its diseases. The recently developed human brain organotypic culture model is one highly promising model that requires the involvement of neurosurgeons and neurosurgical patients. Studies have investigated the electrophysiological properties of neurons in such ex vivo human tissues, but the maintenance of other cell types within explanted brain remains largely unknown. Here, using single-nucleus RNA sequencing, we systematically evaluate the transcriptional identities of the various cell types found in six patient samples after fourteen days in culture (83,501 nuclei from day 0 samples and 45,738 nuclei from day 14 samples). We used two pediatric temporal lobectomy samples, an adult frontal cortex sample, two IDH wild-type glioblastoma samples, and one medulloblastoma sample. We found remarkably high correlations of day 14 transcriptional identities to day 0 tissue, especially in tumor cells (r = 0.90 to 0.93), though microglia (r = 0.86), oligodendrocytes (r = 0.80), pericytes (r = 0.77), endothelial cells (r = 0.78), and fibroblasts (r = 0.76) showed strong preservation of their transcriptional profiles as well. Astrocytes and excitatory neurons showed more moderate preservation (r = 0.66 and 0.47, respectively). Because the main difficulty with organotypic brain cultures is the acquisition of human tissue, which is readily available to neurosurgeons, this model is easily accessible to neurosurgeon-scientists and neurosurgeons affiliated with research laboratories. Broad uptake of this more representative model should prompt advances in our understanding of many uniquely human diseases, lead to more reliable clinical trial performance, and ultimately yield better therapies for our patients., Competing Interests: Declaration of interest statement None of the authors have any conflict of interest with the study or any of the topics discussed.

Objective: Tumors in the ventral craniocervical junction (CCJ) pose unique challenges, particularly in children. The potential constraints with endoscopic approaches to tumors extending inferiorly and laterally and the risk of CSF leakage can be exacerbated in the pediatric population. Here, the authors present their experience with the extreme lateral transodontoid (ELTO) approach in children with large ventral CCJ tumors as an alternative or complement to anterior approaches., Methods: This is a retrospective, single-center study of patients who underwent the ELTO approach from January 2021 to January 2024. Patients with at least 3 months of postoperative follow-up and postoperative MR images were included. Primary outcomes included extent of resection, intraoperative and postoperative complications, and neurological outcome., Results: Six children underwent 8 ELTO approaches (2 children underwent bilateral ELTO). The median age was 8 years (range 3-17 years), with a mean follow-up of 15.8 months. Diagnoses included classic chordoma (n = 3), poorly differentiated chordoma (n = 2), and high-grade undifferentiated sarcoma (n = 1). Gross-total resection (GTR) was achieved in all cases. One patient developed thrombosis of the third segment of the vertebral artery without symptoms or signs of ischemia. One patient with hydrocephalus and significant dysphagia due to bilateral cranial nerve XII palsy at diagnosis and worsening left vocal cord paralysis after the resection required ventriculoperitoneal shunt placement as well as a tracheostomy and gastrostomy after tumor resection. One patient required revision of the occipitocervical fixation due to new onset of dysphagia 4 months after tumor resection, without additional consequences., Conclusions: The ELTO approach is safe and feasible in children with large tumors of the ventral craniocervical junction. GTR was achieved in all the patients, and there were no significant complications or new neurological deficits due to the approach.

Prenatal repair of myelomeningocele (MMC) is associated with lower rates of hydrocephalus requiring ventriculoperitoneal shunt and improved motor function when compared with postnatal repair. Efforts aiming to develop less invasive surgical techniques to decrease the risk for the pregnant patient while achieving similar benefits for the fetus have led to the implementation of fetoscopic surgical techniques. While no ideal anesthetic technique for fetoscopic MMC repair has been demonstrated, we present our anesthetic approach for these repairs, including considerations for both the pregnant patient and the fetus. We emphasize the importance of the preoperative consultation to optimize any medical conditions and to set expectations for the perioperative course. Our preferred anesthetic technique for the pregnant patient includes general anesthesia with an epidural for postoperative analgesia. Intraoperative anesthetic considerations for patients undergoing fetoscopic surgery include tocolysis, meticulous control of hemodynamics, judicious fluid administration, and maternal temperature regulation. We also avoid long-acting neuromuscular blocking agents due to significant weakness observed when given in combination with magnesium sulfate. While the maternal anesthetic crosses the placenta, direct administration of anesthesia to the fetus is required to reliably blunt the stress response. Additional considerations for the fetus include monitoring, fetal resuscitation strategies, and the theoretical risk of anesthetic neurotoxicity. Postoperatively, we use a multi-modal, opioid sparing regimen for analgesia. As advances in fetal surgery aiming to minimize risk to the pregnant patient alter the surgical approach, maternal-fetal anesthesiologists must adapt and incorporate the unique considerations of fetoscopy into their anesthetic management., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Purpose: This Hydrocephalus Clinical Research Network (HCRN) study had two aims: (1) to compare the predictive performance of the original ETV Success Score (ETVSS) using logistic regression modeling with other newer machine learning models and (2) to assess whether inclusion of imaging variables improves prediction performance using machine learning models., Methods: We identified children undergoing first-time ETV for hydrocephalus that were enrolled prospectively at HCRN sites between 200 and 2020. The primary outcome was ETV success 6 months after index surgery. The cohort was randomly divided into training (70%) and testing (30%) datasets. The classic ETVSS variables were used for logistic regression and machine learning models. Predictive performance of each model was evaluated on the testing dataset using area under the receiver operating characteristic curve (AUROC)., Results: There were 752 patients that underwent first time ETV, of which 185 patients (24.6%) experienced ETV failure within 6 months. For aim 1, using the classic ETVSS variables, machine learning models did not outperform logistic regression with AUROC 0.60 (95% CI: 0.52-0.69) for Naïve Bayes (highest machine learning model performance) and 0.68 (95% CI: 0.60-0.76) for logistic regression. After inclusion of imaging features (aim 2), machine learning model prediction improved but remained no better than the above logistic regression with the highest AUROC of 0.67 (95% CI: 0.59-0.75) attained using Naïve Bayes architecture compared to 0.68 (95% CI: 0.59-0.76) for logistic regression., Conclusions: This contemporary multicenter observational cohort study demonstrated that machine learning modeling strategies did not improve performance of the ETVSS model over logistic regression., Competing Interests: Declarations.

Objective: This study reports the infant to preschool outcomes of a laparotomy-assisted, two-port fetoscopic myelomeningocele (MMC) repair and compares the results with those of a contemporary, same-center cohort that underwent either fetal MMC surgery via hysterotomy or postnatal MMC repair., Methods: All MMC closures between December 2011 and July 2021 were screened. Singleton pregnancies with hindbrain herniation and MMC between T1 and S1 were included. Fetuses were excluded for genetic abnormalities, severe kyphosis, and other congenital anomalies. The pregnant woman determined the method of MMC repair (fetoscopic, hysterotomy, or postnatal repair)., Results: Two hundred MMC closures met the study criteria (100 fetoscopic, 41 hysterotomy, and 59 postnatal). The median length of follow-up was beyond 46 months for all groups. The median gestational age at delivery was 38.1 weeks (IQR 35.1, 39.1 weeks) for the fetoscopic group, 35.7 weeks (IQR 33.6, 37.0 weeks) for the hysterotomy group, and 38.6 weeks (IQR 37.7, 39.0 weeks) for the postnatal group. Vaginal delivery occurred in 51% of the fetoscopic cases, and there were no instances of uterine dehiscence or rupture. Treatment for hydrocephalus in the 1st year occurred in 35% (95% CI 27%-50%) of fetoscopic, 33% (95% CI 20%-50%) of hysterotomy, and 81% (95% CI 70%-90%) of postnatal repair cases. At 30 months, patients who underwent fetal intervention were twice as likely to be community ambulators (with or without devices) as those who underwent postnatal repair (52% [95% CI 42%-62%] of fetoscopic, 54% [95% CI 39%-68%] of hysterotomy, and 24% [95% CI 14%-36%] of postnatal cases). Surgery for symptomatic tethered cord occurred in 12% (95% CI 7%-19%) of fetoscopic, 17% (95% CI 8%-31%) of hysterotomy, and 2% (95% CI 1%-8%) of postnatal repair cases. Surgery for symptomatic spinal inclusion cysts was required in 4% (95% CI 1%-9%) of fetoscopic, 7% (95% CI 2%-18%) of hysterotomy, and none (95% CI 0%-8%) of the postnatal cases., Conclusions: Laparotomy-assisted, two-port fetoscopic repair provides significant benefits for maternal health. It negates the risk of uterine rupture for the index pregnancy and subsequent pregnancies and allows for vaginal delivery. The benefits to the fetus are the same as those of hysterotomy repairs, with a lower risk of prematurity. There was no difference in the rate of surgery for tethered cord or spinal inclusion cysts between fetoscopic and hysterotomy procedures. Overall, laparotomy-assisted, two-port fetoscopic repair is safer for the fetus and the mother than fetal MMC surgery via hysterotomy.

Introduction: Outcomes for pineal region and superior cerebellar tumors in young children often hinge on extent of microsurgical resection, and thus choosing an approach that provides adequate visualization of pathology is essential. The occipital interhemispheric transtentorial (OITT) approach provides excellent exposure while minimizing cerebellar retraction. However, this approach has not been widely accepted as a viable option for very young children due to concerns for potential blood loss when incising the tentorium. The aim of this paper is to characterize our recent institutional experience with the occipital interhemispheric transtentorial approach (OITT) for tumor resection in infants and toddlers., Methods: A retrospective study was performed between 2016 and 2023 of pediatric patients less than 36 months of age who underwent OITT for tumor resection at a high-volume referral center. Patients with at least 3 months of postoperative follow-up and postoperative MRI were included. Primary outcomes included extent of resection, intraoperative and postoperative complications, and neurologic outcome. Secondary outcomes included length of stay and estimated blood loss., Results: Eight patients, five male, were included. The median age at the time of surgery was 10 months (range 5-36 months). Presenting symptoms included macrocephaly, nausea/vomiting, strabismus, gait instability, or milestone regression. Hydrocephalus was present preoperatively in all patients. Average tumor volume was 38.6 cm 3 , ranging from 1.3 to 71.9 cm 3 . All patients underwent an OITT approach for tumor resection with stereotactic guidance. No intraoperative complications occurred, and no permanent neurologic deficits developed postoperatively. Gross total resection was achieved in all cases per postoperative MRI report, and no instances of new cerebellar, brainstem, or occipital lobe ischemia were noted., Conclusions: OITT approach for tumor resection in very young children (≤ 36 months) is an effective strategy with an acceptable safety profile. In our series, no significant intraoperative or postoperative complications occurred. To our knowledge, this is the first report describing this technique specifically in patients less than 36 months of age., (© 2024.

Introduction: Spina bifida (SB) occurs in 3.5/10,000 live births and is associated with significant long-term neurologic and urologic morbidity. We explored the characteristics and outcomes of pediatric patients with SB and the facilities that treat them in Texas., Methods: We retrospectively reviewed a statewide hospital inpatient discharge database (2013-2021) to identify patients aged <18 y with SB using International Classification of Diseases 9/10 codes. Patients transferred to outside hospitals were excluded to avoid double-counting. Descriptive statistics and chi-square test were performed., Results: Seven thousand five hundred thirty one inpatient hospitalizations with SB were analyzed. Most SB care is provided by a few facilities. Two facilities (1%) averaged >100 SB admissions per year (33% of patients), while 15 facilities (8%) treat 10-100 patients per year (51% of patients). Most facilities (145/193, 75%) average less than one patient per year. Infants tended to be sicker (17% extreme illness severity, P < 0.001). Overall mortality is low (1%), primarily occurring in the neonatal period (8%, P < 0.001). Most admissions are associated with surgical intervention, with 63% of encounters having operating room charges with an average cost of $25,786 ± 24,884. Admissions for spinal procedures were more common among infants, whereas admissions for genitourinary procedures were more common among older patients (P < 0.001). The average length of stay was 8 ± 16 d with infants having the longest length of stay (19 ± 33, P < 0.001)., Conclusions: Patients have significant long-term health needs with evolving pediatric surgical indications as they grow. Pediatric SB care is primarily provided by a small number of facilities in Texas. Longitudinal care coordination of their multidisciplinary surgical care is needed to optimize patient care., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Objectives: To compare the ambulatory status of a cohort of children who had undergone prenatal repair of an open neural tube defect (ONTD) using one of two different methods (fetoscopic or open hysterotomy) with that of a cohort who had undergone postnatal repair, and to identify the best predictors of ambulation at 30 months of age., Methods: This was a retrospective review of a cohort of children who underwent ONTD repair either prenatally (n = 110), by fetoscopic surgery (n = 73) or open hysterotomy surgery (n = 37), or postnatally (n = 51), in a single tertiary hospital between November 2011 and May 2023. The cohort comprised a consecutive sample of cases who had undergone ONTD repair in-utero following Management of Myelomeningocele Study (MOMS) trial criteria and cases who had undergone postnatal repair, meeting the same criteria, which were also followed up after birth at the same institution. Motor function assessment by ultrasound was recorded at referral, 6 weeks after prenatal repair, or after referral in postnatally repaired cases, and at the last ultrasound scan before delivery. Clinical examinations to assess motor function at birth and at 12 months were retrieved from records. Intact motor function was defined as first sacral myotome (S1) motor function. Ambulatory status data at each follow-up visit were collected. The proportion of children who were able to walk independently after 30 months of age was compared between those who had undergone fetoscopic vs open prenatal surgery and between prenatal (by either fetoscopic or open surgery) and postnatal ONTD repair. Logistic regression analyses were performed to identify predictors for independent ambulation., Results: After 30 months, the proportion of infants who were able to walk independently was higher in prenatally vs postnatally repaired cases (51.8% vs 15.7%, P < 0.01), and there was no difference between those with fetoscopic (52.1%) vs open (51.4%) prenatal repair (P = 0.66). In the prenatally repaired group, having intact motor function at 12 months (adjusted odds ratio (aOR), 9.14 (95% CI, 2.64-31.63), P < 0.01) and at birth (aOR, 4.50 (95% CI, 1.21-16.80), P = 0.02) were significant predictors of independent walking at 30 months; an anatomical level of lesion below L2 at referral (aOR, 1.83 (95% CI, 1.30-2.58), P = 0.01) and female gender (aOR, 3.51 (95% CI, 1.43-8.61), P < 0.01) were also predictive for this outcome., Conclusions: Prenatally repaired cases of ONTD have a better chance of being able to walk independently at 30 months than do those who undergo postnatal repair. In patients with prenatally repaired ONTD, ambulatory status at 30 months can be predicted by observing a low lesion level at referral (below L2) and intact motor function postnatally. These results have implications for parental counseling and planning for supportive therapy in pregnancies affected by ONTD. © 2024 International Society of Ultrasound in Obstetrics and Gynecology., (© 2024 International Society of Ultrasound in Obstetrics and Gynecology.)

Objective: The purpose of this study was to conduct a literature review on transition programs from pediatric to adult care and the role of neurosurgery as individuals with spina bifida (SB) transition, and to provide a framework for neurosurgical providers to assist in the transition to adult-centered care., Methods: A comprehensive literature review was conducted according to the PRISMA statement, with a search in Medline and Embase to identify US clinical programs reporting on their experiences establishing a transition program for adolescents and young adults with SB. Data were collected for authors, year, transition clinic location, model of care for transition clinic, ages served, and specialty clinical team., Results: The literature search yielded 698 articles, 5 of which met the inclusion criteria. These 5 studies included 4 transition programs for which models of care and approach to transition, clinical services involved, establishment of goals, and age of initiation and transition were identified. All programs described setting transition goals, ranging from community services, to self-management, to health care navigation, to patient-driven goals, with 1 program reporting a quality-of-life measurement component to their model., Conclusions: Robust SB transition programs can be established by applying the expanded chronic care model, reviewing lessons learned by other programs, advocating at the institutional level, and seeking support via professional organizations. While the comprehensive role of neurosurgical providers in these programs is still being defined, a shared vision of enhancing the health and quality of life for individuals with SB and their families is needed by all subspecialists involved.
