RESUMO
OBJECTIVES: Urinary tract infections (UTIs) are common, but overdiagnosed, in children with spina bifida. We sought to evaluate the diagnostic test characteristics of urinalysis (UA) findings for symptomatic UTI in children with spina bifida. METHODS: Retrospective cross-sectional study using data from 2 centers from January 1, 2016, to December 31, 2021. Children with myelomeningocele aged <19 years who had paired UA (and microscopy, when available) and urine culture were included. The primary outcome was symptomatic UTI. We used generalized estimating equations to control for multiple encounters per child and calculated area under the receiver operating characteristics curve, sensitivity, and specificity for positive nitrites, pyuria (≥10 white blood cells/high-powered field), and leukocyte esterase (more than trace) for a symptomatic UTI. RESULTS: We included 974 encounters from 319 unique children, of which 120 (12.3%) met our criteria for UTI. Pyuria had the highest sensitivity while nitrites were the most specific. Comparatively, nitrites were the least sensitive and pyuria was the least specific. When the cohort was limited to children with symptoms of a UTI, pyuria remained the most sensitive parameter, whereas nitrites remained the least sensitive. Nitrites continued to be the most specific, whereas pyuria was the least specific. Among all encounters, the overall area under the receiver operating characteristics curve for all components of the UA was lower in children who use clean intermittent catheterizations compared with all others. CONCLUSIONS: Individual UA findings have moderate sensitivity (leukocyte esterase or pyuria) or specificity (nitrites) but overall poor diagnostic accuracy for symptomatic UTIs in children with spina bifida.

PURPOSE: We sought to assess associations between health-related quality of life (QOL), bladder-related QOL, bladder symptoms, and bladder catheterization route among adolescents and young adults with spina bifida. MATERIALS AND METHODS: Clinical questionnaires administered to individuals ≥ 12 years old requiring catheterization between June 2019 to March 2020 in a spina bifida center were retrospectively analyzed. Questionnaires were completed in English or Spanish independently or with caregiver assistance. Medical records were reviewed for demographic and clinical characteristics. Primary exposure was catheterization route (urethra or channel). Primary outcome was health-related QOL, measured by Patient-Reported Outcomes Measurement Information System Pediatric Global Health 7 (PGH-7). Secondary outcomes were bladder-related QOL and bladder symptoms, measured by Neurogenic Bladder Symptom Score (NBSS). Nested, multivariable linear regression models assessed associations between catheterization route and questionnaire scores. RESULTS: Of 162 patients requiring catheterization, 146 completed both the PGH-7 and NBSS and were included. Seventy-three percent were catheterized via urethra and 27% via channel. Median age was 17.5 years (range 12-31), 58% of patients were female, and 80% had myelomeningocele. Urinary incontinence was more common among those who catheterized via urethra (60%) compared to channel (33%). On adjusted analyses, catheterization route was not significantly associated with PGH-7 or NBSS bladder-related QOL scores. More bladder symptoms were associated with worse bladder-related QOL. Patients who catheterized via channel had fewer bladder symptoms than those who catheterized via urethra. CONCLUSIONS: Catheterization route was not significantly associated with QOL. Though catheterization via channel was associated with fewer bladder symptoms, only degree of current bladder symptoms was significantly associated with bladder-related QOL.

AIM: To assess perspectives on clinical communication about sexual health in young adult males with spina bifida. METHOD: Semi-structured interviews were conducted between February and May 2021 with males at least 18 years of age with spina bifida to assess their perspectives and experiences of sexual health communication with clinicians. Demographic and clinical characteristics were obtained from chart review and a survey of patients. Interviews were transcribed verbatim, and conventional content analysis was used for transcript coding. RESULTS: Twenty individuals participated with a median age of 22 years 6 months (range 18-29 years). Sixteen had myelomeningocele. Most identified as heterosexual (n = 17) and not sexually active (n = 13). Barriers and facilitators of successful interactions were identified. Barriers for participants included general discomfort with talking about sex and variability in individual preferences for how conversations occur. Facilitators included participants' comfort with their urologist and discussing sex in relation to disability. Suggestions for improving discussions included (1) notifying individuals that discussion about sex will occur before clinic visits; (2) creating space for discussions; (3) respecting individuals' readiness to discuss; and (4) making discussions disability specific. INTERPRETATION: Young adult males with spina bifida are interested in discussing sexual health with their clinicians. Great variability exists about conversation preferences, emphasizing the need to individualize clinical communication about sex. Current health guidelines for males may not be in line with individuals' wishes. WHAT THIS PAPER ADDS: Great variability exists in individual preference around sexual health communication. Patient-level barriers hinder successful conversations about sex. Individuals have great insight into how conversations about sex can be improved.

OBJECTIVE: To compare differences in bowel-specific quality of life (QOL), overall qQOL, and neurogenic bowel dysfunction (NBD) severity by bowel management program in patients with spina bifida (SB). METHODS: We performed a retrospective cross-sectional study of patients ≥12 years old at our multidisciplinary SB center who completed both a modified Peristeen NBD questionnaire (assessing bowel symptom severity and bowel-specific QOL) and the Patient-Reported Outcomes Measurement Information System Pediatric Global Health questionnaire (assessing overall QOL). Nested, multivariable models were fit for associations between outcomes and bowel management program (enemas, conservative management, and none). RESULTS: A total of 173 patients, 56.1% female and 64.6% with myelomeningocele, were included in our analysis. Median age was 18.2 years old. Patients reported using enemas (n = 42), conservative management (n = 63), and no bowel program (n = 68). When adjusting for covariates, there was no significant association between bowel-specific QOL nor overall QOL across bowel management programs. However, the use of conservative management compared to enemas was associated with worse bowel symptoms severity (adjusted beta=2.58, 95%CI=[0.09,5.06]). Additionally, greater bowel symptom severity was significantly associated with lower overall QOL (adjusted beta=-0.33, 95%CI=[-0.57,-0.10]). CONCLUSION: NBD symptom severity in SB is more strongly associated with QOL than the individual bowel program being utilized. Our findings suggest that different degrees of NBD require different invasiveness of bowel programs, but it is the outcome of the bowel management program and not the specific program itself that is most associated with QOL.

PURPOSE: This study aimed to analyze organ system-based causes and non-organ system-based mechanisms of death (COD, MOD) in people with myelomeningocele (MMC), comparing urological to other COD. METHODS: A retrospective review was performed of 16 institutions in Canada/United States of non-random convenience sample of people with MMC (born > = 1972) using non-parametric statistics. RESULTS: Of 293 deaths (89% shunted hydrocephalus), 12% occurred in infancy, 35% in childhood, and 53% in adulthood (documented COD: 74%). For 261 shunted individuals, leading COD were neurological (21%) and pulmonary (17%), and leading MOD were infections (34%, including shunt infections: 4%) and non-infectious shunt malfunctions (14%). For 32 unshunted individuals, leading COD were pulmonary (34%) and cardiovascular (13%), and leading MOD were infections (38%) and non-infectious pulmonary (16%). COD and MOD varied by shunt status and age (p < = 0.04), not ambulation or birthyear (p > = 0.16). Urology-related deaths (urosepsis, renal failure, hematuria, bladder perforation/cancer: 10%) were more likely in females (p = 0.01), independent of age, shunt, or ambulatory status (p > = 0.40). COD/MOD were independent of bladder augmentation (p = >0.11). Unexplained deaths while asleep (4%) were independent of age, shunt status, and epilepsy (p >= 0.47). CONCLUSION: COD varied by shunt status. Leading MOD were infectious. Urology-related deaths (10%) were independent of shunt status; 26% of COD were unknown. Life-long multidisciplinary care and accurate mortality documentation are needed.

INTRODUCTION: Management of obstructing ureterocele often includes endoscopic transurethral incision (TUI) that can be challenging secondary to uncertainty in anatomic landmarks with risk of serious complications. To this end, we innovated a technique using predictable landmarks that begins endoscopic incision at the ureterocele orifice and extends retrograde proximal to the bladder neck (Figure). OBJECTIVE: With over 15 years of experience in performing this retrograde incision from orifice (RIO) technique, we aimed to examine post-operative outcomes and risk of surgical failure after RIO compared to traditional TUI techniques for ureteroceles. We hypothesized that clinical outcomes after RIO would be superior to traditional endoscopic approaches to decompression of obstructing ureterocele in infants. STUDY DESIGN: A retrospective study of patients ≤12 months old who underwent TUI ureterocele at our institution between 2007 and -2021 was conducted. Pre-, intra- and post-operative characteristics were compared between patients who underwent RIO vs non-RIO TUI. Primary outcome was post-incision febrile urinary tract infection (fUTI). Secondary outcome was a composite failure measure of fUTI, secondary surgery, de novo bladder outlet obstruction, or vesicoureteral reflux. Multivariable Cox proportional hazard models were fitted to compare the time-to-event risk of primary and secondary outcomes between groups. RESULTS: Ninety patients with 92 ureteroceles were included (49 RIO, 43 non-RIO). Median follow-up from TUI was 33 months. RIO had a shorter median operative duration (27 vs 35 min, p = 0.021). Primary and secondary outcomes were similar between groups (fUTI: 29% RIO vs 19% non-RIO, p = 0.27; composite failure 54% RIO vs 69% non-RIO, p = 0.15). In multivariable Cox proportional hazard models, there was no significant difference in risk of fUTI (RIO aHR 0.98, 95% CI 0.38-2.54, p = 0.97) or composite failure (RIO aHR 0.80, 95% CI 0.45-1.44, p = 0.46) between TUI techniques. DISCUSSION: RIO technique for TUI ureterocele is attractive in that it uses predictable anatomic landmarks making it simple to perform. In analyzing this 15-year institutional experience of TUI ureterocele, RIO showed similar success to non-RIO endoscopic incisions. This study is a retrospective, non-randomized, single-institutional study over 15 years and is therefore subject to change in surgeon practice over time and variable practices between providers. CONCLUSIONS: Given comparable success and durability over time to other TUI ureterocele techniques, and with the advantage of operator ease using consistent anatomic landmarks, RIO is a worthy option for endoscopic ureterocele decompression.

PURPOSE: We evaluate the applicability of the International Index of Erectile Function in young men with spina bifida and identify spina bifida-specific sexual experiences not captured by this measure. MATERIALS AND METHODS: Semistructured interviews were conducted between February 2021 and May 2021 with men ≥18 years of age with spina bifida. The International Index of Erectile Function was completed by participants, and perspectives on its applicability were discussed. Participant experiences and perspectives around sexual health were discussed to identify aspects of the sexual experience not well captured by the International Index of Erectile Function. Demographic and clinical characteristics were obtained from a patient survey and chart review. Conventional content analysis framework was used for transcript coding. RESULTS: Of 30 eligible patients approached, 20 participated. Median age was 22.5 years (range 18-29), and 80% had myelomeningocele. Most identified as heterosexual (17/20, 85%), were not in a relationship (14/20, 70%), and were not currently sexually active (13/20, 65%). Some perceived the International Index of Erectile Function as applicable, while others reported it was not, as they do not define themselves as sexually active. Aspects of the sexual experience not captured by the International Index of Erectile Function included (1) lack of control over sexual function, (2) poor lower body sensation, (3) urinary incontinence, (4) spina bifida-specific physical limitations, and (5) psychosocial barriers. Participant suggestions for improving the International Index of Erectile Function to increase its applicability were identified. CONCLUSIONS: While many perceived the International Index of Erectile Function as applicable, the measure inadequately captures the diverse sexual experiences of young men with spina bifida. Disease-specific instruments to evaluate sexual health are needed in this population.

PURPOSE: While our institution has historically obtained a urine culture (UCx) from every child at the time of urodynamics (UDS), no consensus exists on UDS UCx utility, and practice varies widely. This study aims to prospectively study our symptomatic post-UDS UTI rate before and after implementing a targeted UCx protocol. MATERIALS AND METHODS: A 2-part prospective study of patients undergoing UDS at one pediatric hospital was undertaken, divided into Phase 1 (7/2016-6/2017) with routine UCx at the time of UDS and Phase 2 (7/2019-6/2020) after implementation of a protocol limiting UCx at the time of UDS to only a targeted subset of patients. The primary outcome was symptomatic post-UDS UTI, defined as positive UCx ≥10Ë4 CFU/mL and fever ≥38.5 °C or new urinary symptoms within seven days of UDS. RESULTS: A total of 1,154 UDS were included: 553 in 483 unique patients during Phase 1 and 601 in 533 unique patients during Phase 2. Age, sex, race, ethnicity, and bladder management did not differ significantly between phases. All 553 UDS in Phase 1 had UCx at the time of UDS, compared to 34% (204/601) in Phase 2. The rate of positive UCx decreased from 39% in Phase 1-35% in Phase 2. Three patients developed symptomatic post-UDS UTI in each study period, resulting in a stable post-UDS UTI rate of 0.5% (3/553) in Phase 1 and 0.5% (3/601) in Phase 2. These patients varied in age, sex, UDS indication, and bladder management. Four of the six (67%) patients had positive UCx at the time of UDS, one had a negative UCx, and one had no UCx under the targeted UCx protocol. Predictors of symptomatic post-UDS UTI could not be evaluated. DISCUSSION: In the largest prospective study to date, we found that symptomatic post-UDS UTI was <1% and that UCx at the time of UDS can safely be limited at our hospital. This reduction has important implications for cost containment and antibiotic stewardship. We will continue iterative modifications to our protocol, which may eventually include the elimination of UCx at the time of UDS in all groups. CONCLUSIONS: This 2-part prospective evaluation at one pediatric hospital determined that the symptomatic post-UDS UTI rate remained <1% with no identifiable predictors after limiting previously universal UCx at the time of UDS to only a targeted subset of patients.

Introduction: Patients with neurogenic urinary incontinence due to an incompetent outlet may be offered bladder neck reconstruction, but the quest for the perfect surgical-outlet procedure continues. Our aim was to characterize continence and complications after modified Mitchell urethral lengthening/bladder neck reconstruction (MMBNR) with sling and to introduce a modification of exposure that facilitates subsequent steps of MMBNR. Methods: A single-institution, retrospective cohort study of patients who underwent primary MMBNR between May 2011 and July 2019 was performed. Data on demographics, urodynamic testing, operative details, unanticipated events, continence, bladder changes, and additional procedures were collected. A 2013 modification that permits identification of the incompetent bladder neck prior to urethral unroofing was applied to the last 17 patients. The trigone and bladder neck are exposed via an oblique low anterolateral incision on the bladder. Ureteral reimplantation is not routinely performed. Focal incision of the endopelvic fascia after posterior plate creation limits breadth of blunt dissection for sling placement. Descriptive statistics were utilized. Results: A total of 25 patients (13 females) had MMBNR with sling at a median age of 10 years [interquartile range (IQR) 8-11]. Bladder augmentation was performed concurrently in 14/25 (56%) patients. At a median of 5.0 (IQR 3.9-7.5) years follow-up after MMBNR, 9/11 (82%) without bladder augmentation and 13/14 (93%) with bladder augmentation had no leakage per urethra during the day without further continence procedures. Of the three patients with persistent incontinence, two achieved continence with bladder wall Botox injection (overall continence 24/25, 96%). New and recurrent vesicoureteral reflux was noted in five patients and one patient, respectively. Two patients required subsequent bladder augmentation for pressures and one other will likely require it. None have required bladder neck closure or revision. Conclusion: MMBNR with sling provides promising continence per urethra in neurogenic bladder with low need for secondary continence procedures. Ongoing modifications may achieve elusive total continence.
RESUMO
OBJECTIVE: The objective of the study was to determine if health literacy is associated with health-related quality of life (HRQOL) in adolescents and young adults (AYAs) with spina bifida. STUDY DESIGN: Between June 2019 and March 2020, the Patient-Reported Outcome Measurement Information System Pediatric Global Health-7 (PGH-7), a measure of HRQOL, and the Brief Health Literacy Screening Tool (BRIEF) were administered to patients ≥12 years old with a diagnosis of spina bifida seen in our multidisciplinary spina bifida center. Questionnaires were completed at scheduled clinic visits. The primary outcome was the PGH-7 normalized T-score. The primary exposure was the BRIEF score. Demographic and clinical characteristics were obtained from the medical record. Nested, multivariable linear regression models assessed the association between health literacy and the PGH-7 score. RESULTS: Of 232 eligible patients who presented to clinic, 226 (97.4%) met inclusion criteria for this study. The median age was 17.0 years (range: 12-31). Most individuals were female (54.0%) and had myelomeningocele (61.5%). Inadequate, marginal, and adequate health literacy levels were reported by 35.0%, 28.3%, and 36.7% of individuals. In univariable analysis, higher health literacy levels were associated with higher PGH-7 scores. In nested, sequentially adjusted multivariable linear regression models, a higher health literacy level was associated with a stepwise increase in the PGH-7 score. In the fully adjusted model, adequate health literacy and marginal health literacy, compared with inadequate health literacy, were associated with increases in a PGH-7 score of 3.3 (95% CI: 0.2-6.3) and 1.1 (95% CI: -2.0 to 4.2), respectively. CONCLUSIONS: Health literacy was associated with HRQOL after adjusting for demographic and clinical factors. Strategies incorporating health literacy are needed to improve HRQOL in AYAs with spina bifida.

PURPOSE: Deferring bladder augmentation (BA) may be desirable in a pediatric neurogenic bladder (NGB) with worsening compliance, but prior studies have questioned whether onabotulinum toxin A (BTX) demonstrates durable improvement in compliance. We present our overall experience with BTX and its role in mitigating the "at-risk" NGB, as determined by urodynamic characteristics. METHODS: A retrospective single-institution review of all BTX procedures performed during January 2010 to October 2018 was conducted. Patients with <12 months follow-up after first BTX injection were excluded. Urodynamic studies (UDS) were reviewed to assign National Spina Bifida Patient Registry (NSBPR) as well as institutionally developed (LCH) risk classification groups. Patients were considered "at-risk" for BA if they had any of the following: NSBPR risk grade of intermediate or hostile; LCH risk grades indicating end-fill pressure >25 cmH2 O or detrusor sphincter dyssynergia (DSD); upper tract changes including new hydronephrosis; new or worsening vesicoureteral reflux; or other signs of a hostile urinary tract (i.e., febrile UTIs). UDS risk grades pre and post-first BTX injection were compared in this "at-risk" group, when available. RESULTS: Thirty-nine patients underwent 162 injection procedures over a median follow-up of 65 months interquartile range (IQR 49-81). Median age at first BTX was 10 years and the median number of BTX injections per patient was 4 (IQR 2-7; range 1-12) with a median time of 6 months between injections (IQR 4-10). Twenty-six patients were deemed "at-risk" at the time of first BTX injection, and of those, 16 (61.5%) proceeded to BA at a median of 36 months (IQR 22.5-42). A small number (four) had BA due to upper tract changes or worsening pressures on BTX, while nine patients (five with CKD) proceeded to BA given a lack of sufficient improvement to consider BTX a long-term viable option. Post-first BTX UDS demonstrated downgrading of risk group in 38% and 63% using NSBPR and LCH classifications, respectively. CONCLUSIONS: Encouraging improvements in the urodynamic risk group were noted in some patients. With careful counseling and follow-up, BTX may safely extend the time to BA in some "at-risk" patients.

OBJECTIVE: The impact of parent-reported stigma due to their child's disorder/difference of sex development (DSD) on parent psychosocial adjustment is poorly understood. In other pediatric populations, perceived interference of medical conditions into daily activities (i.e., illness intrusiveness ) mediates the relationship of stigma to adjustment. This study assessed relationships between parent-focused and child-focused stigma â illness intrusiveness â depressive and anxious symptoms . Exploratory analyses sought to identify patient characteristics associated with stigma. METHOD: Caregivers (59 women and 43 men) of 63 children diagnosed with a DSD up to age 4 years completed measures of demographics, parent-focused and child-focused stigma, illness intrusiveness, and depressive and anxious symptoms. RESULTS: Increased parent-focused and child-focused stigma were associated with increased illness intrusiveness, which, in turn, was associated with increased depressive and anxious symptoms for parents nested within dyads. Among children with DSD family histories, parents reported greater child-focused stigma. CONCLUSION: Parents who experience DSD-related stigma report greater interference of their child's DSD into their daily activities, which is associated with poorer psychosocial adjustment. Findings support developing clinical interventions related to parents' perceptions of stigma and illness intrusiveness to improve parent adjustment.

OBJECTIVE: Myelocystocele (MCC) is an uncommon form of skin-covered spinal dysraphism. The authors aimed to present long-term functional outcomes of patients treated for MCC with and without associated abnormalities of cloacal development (ACD). METHODS: All patients with MCC and at least one tethered cord release (TCR) treated at a single institution between 1982 and 2019 were retrospectively reviewed. Demographic, operative, and functional outcome data were analyzed. RESULTS: Of 51 children with MCC, 30 (58.8%) had MCC only and 21 (41.2%) had associated ACD (MCC/ACD). Thirty-two patients (62.7%) had undergone one TCR, while 19 patients (37.3%) had multiple TCRs. Urinary continence assessment was possible in 41 patients (80.4%), and bowel continence assessment was possible in 43 patients (84.3%) who were either older than 6 years or toilet trained. Although patients with MCC only were more likely to void volitionally (p = 0.0001), there was no difference in overall bladder continence based on the presence of ACD (p = 0.15) or the need for additional untethering procedures (p = 0.15). Those with MCC only were more likely to have overall bowel continence (p = 0.0001) and not require any management (p = 0.002), while those with MCC/ACD were more likely to have an ileostomy (p = 0.01). Of the 30 patients with MCC only, 29 (96.7%) were able to ambulate in the community. Of 21 patients with MCC/ACD, 14 (66.7%) were able to ambulate in the community, 5 (23.8%) were not ambulating, and 2 (9.5%) were therapeutic ambulators. A greater proportion of children in the MCC cohort were ambulating in the community (p = 0.01). There was no difference in community ambulation based on the number of TCRs (p > 0.99), but those with multiple TCRs were more likely to use braces (p = 0.01) and require lower-extremity orthopedic surgery (p = 0.01). CONCLUSIONS: Patients born with an MCC, with or without an associated ACD, attained long-term favorable outcomes in bladder and bowel continence and ambulation.

The small arginine-rich protein protamine condenses complete genomic DNA into the sperm head. Here, we applied its high RNA binding capacity for spontaneous electrostatic assembly of therapeutic nanoparticles decorated with tumour-cell-specific antibodies for efficiently targeting siRNA. Fluorescence microscopy and DLS measurements of these nanocarriers revealed the formation of a vesicular architecture that requires presence of antibody-protamine, defined excess of free SMCC-protamine, and anionic siRNA to form. Only these complex nanoparticles were efficient in the treatment of non-small-cell lung cancer (NSCLC) xenograft models, when the oncogene KRAS was targeted via EGFR-mediated delivery. To show general applicability, we used the modular platform for IGF1R-positive Ewing sarcomas. Anti-IGR1R-antibodies were integrated into an antibody-protamine nanoparticle with an siRNA specifically against the oncogenic translocation product EWS/FLI1. Using these nanoparticles, EWS/FLI1 knockdown blocked in vitro and in vivo growth of Ewing sarcoma cells. We conclude that these antibody-protamine-siRNA nanocarriers provide a novel platform technology to specifically target different cell types and yet undruggable targets in cancer therapy by RNAi.

BACKGROUND: Use of prophylactic antibiotics after stented hypospadias repair is very common, but most research has not identified any clinical benefits of this practice. Only one study has found that postoperative prophylaxis reduces symptomatic urinary tract infections (UTIs). Data from the same trial suggested that prophylaxis may also reduce urethroplasty complications. No studies on this subject have been placebo-controlled. OBJECTIVE: We performed a randomized, double-blind, placebo-controlled study to evaluate the effect of postoperative prophylactic antibiotics on the incidence of infection or urethroplasty complications after stented repair of midshaft-to-distal hypospadias. STUDY DESIGN: Boys were eligible for this multicenter trial if they had a primary, single-stage repair of mid-to-distal hypospadias with placement of an open-drainage urethral stent for an intended duration of 5-10 days. Participants were randomized in a double-blind fashion to receive oral trimethoprim-sulfamethoxazole or placebo twice daily for 10 days postoperatively. The primary outcome was a composite of symptomatic UTI, surgical site infection (SSI), and urethroplasty complications, including urethrocutaneous fistula, meatal stenosis, and dehiscence. Secondary outcomes included each component of the primary outcome as well as acute adverse drug reactions (ADRs) and C. difficile colitis. RESULTS: Infection or urethroplasty complications occurred in 10 of 45 boys (22%) assigned to receive antibiotic prophylaxis as compared with 5 of 48 (10%) who received placebo (relative risk [RR], 2.1; 95% confidence interval [CI], 0.8 to 5.8; p = 0.16). There were no significant differences between groups in symptomatic UTIs, SSIs, or any urethroplasty complications. Mild ADRs occurred in 3 of 45 boys (7%) assigned to antibiotics as compared with 5 of 48 (10%) given placebo (RR, 0.6; 95% CI, 0.2 to 2.5; p = 0.72). There were no moderate-to-severe ADRs, and no patients developed C. difficile colitis. CONCLUSIONS: In this placebo-controlled trial of 93 patients, prophylactic antibiotics were not found to reduce infection or urethroplasty complications after stented mid-to-distal hypospadias repair. The study did not reach its desired sample size and was therefore underpowered to independently support a conclusion that prophylaxis is not beneficial.

Importance: Health literacy has been shown to play an important role in transitions of care in adult populations, with low health literacy associated with adverse health outcomes. The role of health literacy in the transition from pediatric to adult care has been less well studied. Among adolescents and young adults with spina bifida, high rates of unsuccessful transition have been shown, but how patient health literacy affects transition readiness remains unknown. Objective: To determine whether health literacy is associated with transition readiness in adolescents and young adults with spina bifida. Design, Setting, and Participants: This cross-sectional study involved collection of patient-reported questionnaires between June 2019 and March 2020 at a multidisciplinary spina bifida center at a single, free-standing children's hospital. Patient demographic and clinical characteristics were obtained from medical record review. Patients were aged 12 years or older with a diagnosis of spina bifida (myelomeningocele and nonmyelomeningocele) whose primary language was English or Spanish. Data analysis was performed from October 2020 to March 2021. Exposures: Health literacy as assessed by the Brief Health Literacy Screening Tool. Main Outcomes and Measures: The primary outcome was total Transition Readiness Assessment Questionnaire (TRAQ) score, normalized into units of SD. Nested, multivariable linear regression models assessed the association between health literacy and TRAQ scores. Results: The TRAQ and Brief Health Literacy Screening Tool were completed by 200 individuals (median [range] age, 17.0 [12.0-31.0] years; 104 female participants [52.0%]). Most of the patients were younger than 18 years (110 participants [55.0%]) and White (136 participants [68.0%]) and had myelomeningocele (125 participants [62.5%]). The mean (SD) TRAQ score was 3.3 (1.1). Sixty-six participants (33.0%) reported inadequate health literacy, 60 participants (30.0%) reported marginal health literacy, and 74 participants (37.0%) reported adequate health literacy. In univariable analysis, health literacy, age, type of spina bifida, level of education, self-administration vs completion of the questionnaires with assistance, ambulatory status, and urinary incontinence were associated with total TRAQ score. In all nested, sequentially adjusted, multivariable models, higher health literacy remained a significant, stepwise, independent variable associated with higher TRAQ score. In the fully adjusted model, having adequate compared with inadequate health literacy was associated with an increase in normalized TRAQ score of 0.49 SD (95% CI, 0.19-0.79). Conclusions and Relevance: Patient-reported transition readiness is associated with health literacy, even after adjustment for education level and other demographic and clinical factors. Developing and implementing health literacy-sensitive care programs during the transition process may improve patient transition readiness.

INTRODUCTION: Differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. A phenotype of severe genital atypia in patients raised as male is a relatively rare occurrence and standards for management are lacking. Decision making for early surgical planning in these rare cases includes, but is not limited to, degree of atypia, location of testes, and presence of MÏllerian remnants. In this study we describe surgical approaches and short-term outcomes for masculinizing genitoplasty in moderate to severe genital atypia in young patients raised male, for whom parents opted for early surgery. METHODS: This NIH-sponsored study is an ongoing, observational, multicenter investigation assessing medical, surgical and psychological outcomes in children and their parents affected by atypical genitalia due to DSD. Participants were prospectively enrolled from 12 children's hospitals across the United States that specialize in DSD care. Criteria for child enrollment were a Quigley score of 3-6 in those with a 46, XY or 45,X/46, XY chromosome complement, age <3 years with no previous genitoplasty; patients were included independent of whether genitoplasty was performed. Cosmesis was graded according to a 4-point Likert scale and complications per the Clavian-Dindo classification. RESULTS: Of the 31 participants, 30 underwent hypospadias repair and 1 patient did not undergo a genitoplasty procedure. The majority of participants (22) received a staged hypospadias repair. Seventeen complications were identified in 12 of the 31 children (41%) at 12 months of follow up. Glans dehiscence and urethrocutaneous fistula were the most common complications. Orchiopexy was performed in 14 (44%) and streak gonads were removed in 4 (13%) participants. Both parents and surgeons reported improved cosmesis after surgery when compared to baseline. CONCLUSION: Genitoplasty was chosen by parents for the majority of children eligible for study. No single surgical approach for masculinizing moderate to severe genital ambiguity in young patients with 46, XY or 45,X/46, XY DSD was adopted by all surgeons. Complications occurred in 41% of those who underwent genitoplasty for severe hypospadias. Overall, appearance of the genitals, as determined by parents and surgeons, improved following genitoplasty. Outcomes of early genitoplasty are needed to guide families when making decisions about such procedures for their young children.

OBJECTIVE: This study identifies trajectories of parent depressive symptoms after having a child born with genital atypia due to a disorder/difference of sex development (DSD) or congenital adrenal hyperplasia (CAH) and across the first year postgenitoplasty (for parents who opted for surgery) or postbaseline (for parents who elected against surgery for their child). Hypotheses for four trajectory classes were guided by parent distress patterns previously identified among other medical conditions. METHODS: Participants included 70 mothers and 50 fathers of 71 children diagnosed with a DSD or CAH with reported moderate to high genital atypia. Parents were recruited from 11 US DSD specialty clinics within 2 years of the child's birth and prior to genitoplasty. A growth mixture model (GMM) was conducted to identify classes of parent depressive symptoms over time. RESULTS: The best fitting model was a five-class linear GMM with freely estimated intercept variance. The classes identified were termed "Resilient," "Recovery," "Chronic," "Escalating," and "Elevated Partial Recovery." Four classes have previously been identified for other pediatric illnesses; however, a fifth class was also identified. The majority of parents were classified in the "Resilient" class (67.6%). CONCLUSIONS: This study provides new knowledge about the trajectories of depressive symptoms for parents of children with DSD. Future studies are needed to identify developmental, medical, or familial predictors of these trajectories.
