Journal article (peer-reviewed)abstract
- Purpose: Since pediatric surgeons aim to follow their patients with anorectal malformations (ARM) into adulthood the aim of this study was to investigate how pediatric surgeons deal with sexual issues related to ARM. Methods: In 2018, a questionnaire was developed by the working group “Follow-up and sexuality” of the ARM-Net consortium and sent to all consortium-linked pediatric surgeons from 31 European pediatric surgical centers. Obtained data were statistically analyzed. Results: Twenty-eight of 37 pediatric surgeons (18 males/10 females) answered the questionnaire. The majority of pediatric surgeons (82%) think they should talk about sexual issues with their patient. More than 50% of pediatric surgeons do not feel at all or only moderately confident discussing the topic of sexuality. Most pediatric surgeons require more support (96%) and wish to be trained in sexuality and sexual issues (78%) to feel confident towards their ARM-patients/parents. For optimal care, sexual issues with ARM-patients should be managed by a multidisciplinary team. Conclusions: Pediatric surgeons feel that sexuality is an important issue for their ARM-patients, which they are primarily responsible of but should be managed in concert with a multidisciplinary team. A training in sexuality is wished to feel more confident about this specific issue.

Journal article (peer-reviewed)abstract
- Objectives: To review the current literature and develop consensus conclusions and recommendations on nutrient intakes and nutritional practice in preterm infants with birthweight <1800 g.Methods: The European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee of Nutrition (CoN) led a process that included CoN members and invited experts. Invited experts with specific expertise were chosen to represent as broad a geographical spread as possible. A list of topics was developed, and individual leads were assigned to topics along with other members, who reviewed the current literature. A single face-To-face meeting was held in February 2020. Provisional conclusions and recommendations were developed between 2020 and 2021, and these were voted on electronically by all members of the working group between 2021 and 2022. Where >90% consensus was not achieved, online discussion meetings were held, along with further voting until agreement was reached.Results: In general, there is a lack of strong evidence for most nutrients and topics. The summary paper is supported by additional supplementary digital content that provide a fuller explanation of the literature and relevant physiology: introduction and overview; human milk reference data; intakes of water, protein, energy, lipid, carbohydrate, electrolytes, minerals, trace elements, water soluble vitamins, and fat soluble vitamins; feeding mode including mineral enteral feeding, feed advancement, management of gastric residuals, gastric tube placement and bolus or continuous feeding; growth; breastmilk buccal colostrum, donor human milk, and risks of cytomegalovirus infection; hydrolyzed protein and osmolality; supplemental bionutrients; and use of breastmilk fortifier.Conclusions: We provide updated ESPGHAN CoN consensus-based conclusions and recommendations on nutrient intakes and nutritional management for preterm infants.

A LOFAR observation of ionospheric scintillation from two simultaneous travelling ionospheric disturbances
- 2020
-
In: Journal of Space Weather and Space Climate. - : EDP Sciences. - 2115-7251. ; 10
-
Journal article (peer-reviewed)abstract
- This paper presents the results from one of the first observations of ionospheric scintillation taken using the Low-Frequency Array (LOFAR). The observation was of the strong natural radio source Cassiopeia A, taken overnight on 18-19 August 2013, and exhibited moderately strong scattering effects in dynamic spectra of intensity received across an observing bandwidth of 10-80 MHz. Delay-Doppler spectra (the 2-D FFT of the dynamic spectrum) from the first hour of observation showed two discrete parabolic arcs, one with a steep curvature and the other shallow, which can be used to provide estimates of the distance to, and velocity of, the scattering plasma. A cross-correlation analysis of data received by the dense array of stations in the LOFAR "core" reveals two different velocities in the scintillation pattern: a primary velocity of similar to 20-40 ms(-1) with a north-west to south-east direction, associated with the steep parabolic arc and a scattering altitude in the F-region or higher, and a secondary velocity of similar to 110 ms(-1) with a north-east to south-west direction, associated with the shallow arc and a scattering altitude in the D-region. Geomagnetic activity was low in the mid-latitudes at the time, but a weak sub-storm at high latitudes reached its peak at the start of the observation. An analysis of Global Navigation Satellite Systems (GNSS) and ionosonde data from the time reveals a larger-scale travelling ionospheric disturbance (TID), possibly the result of the high-latitude activity, travelling in the north-west to south-east direction, and, simultaneously, a smaller-scale TID travelling in a north-east to south-west direction, which could be associated with atmospheric gravity wave activity. The LOFAR observation shows scattering from both TIDs, at different altitudes and propagating in different directions. To the best of our knowledge this is the first time that such a phenomenon has been reported.

A Quality Assessment of the ARM-Net Registry Design and Data Collection
- 2023
-
In: Journal of Pediatric Surgery. - : Elsevier BV. - 0022-3468. ; 58:10, s. 1921-1928
-
Journal article (peer-reviewed)abstract
- Background: Registries are important in rare disease research. The Anorectal Malformation Network (ARM-Net) registry is a well-established European patient registry collecting demographic, clinical, and functional outcome data. We assessed the quality of this registry through review of the structure, data elements, collected data, and user experience. Material and methods: Design and data elements were assessed for completeness, consistency, usefulness, accuracy, validity, and comparability. An intra- and inter-user variability study was conducted through monitoring and re-registration of patients. User experience was assessed via a questionnaire on registration, design of registry, and satisfaction. Results: We evaluated 119 data elements, of which 107 were utilized and comprised 42 string and 65 numeric elements. A minority (37.0%) of the 2278 included records had complete data, though this improved to 83.5% when follow-up elements were excluded. Intra-observer variability demonstrated 11.7% incongruence, while inter-observer variability was 14.7%. Users were predominantly pediatric surgeons and typically registered patients within 11–30 min. Users did not experience any significant difficulties with data entry and were generally satisfied with the registry, but preferred more longitudinal data and patient-reported outcomes. Conclusions: The ARM-Net registry presents one of the largest ARM cohorts. Although its collected data are valuable, they are susceptible to error and user variability. Continuous evaluations are required to maintain relevant and high-quality data and to achieve long-term sustainability. With the recommendations resulting from this study, we call for rare disease patient registries to take example and aim to continuously improve their data quality to enhance the small, but impactful, field of rare disease research. Level of Evidence: V.

Urological Impact of Epididymo-orchitis in Patients with Anorectal Malformation : An ARM-Net Consortium Study
- 2022
-
In: European Journal of Pediatric Surgery. - : Georg Thieme Verlag KG. - 0939-7248 .- 1439-359X. ; 32:6, s. 504-511
-
Journal article (peer-reviewed)abstract
- Introduction To investigate the current experience of the ARM-Net Consortium in the management of epididymo-orchitis (EO) in patients with anorectal malformations (ARMs), and to identify specific risk factors and the need for urological care involvement. Materials and Methods We retrospectively collected data of EO in patients with ARM between 2015 and 2019. Data on urological aspects, ARM type, surgical approach, associated anomalies, diagnosis, and treatment of EO were collected and analyzed. Results Twenty-nine patients were reported by 12 centers. Twenty-six patients with EO (90%) had ARM with a rectourinary fistula. Median age at first EO was 2 years (range: 15 days-27 years). Twenty patients (69%) experienced multiple EO, and 60% of recurrences were ipsilateral. Associated urological anomalies included vesicoureteral reflux (48%), urethral anomalies (41%), neurogenic bladder (41%), and ectopic vas (10%). A positive urine culture during EO was present in 69%. EO was treated with antibiotics (90%), limiting surgical exploration to 14%. Prevention of recurrences included surgery (bulking agents 15%, vasectomy 15%, and orchiectomy 5%) and antibiotic prophylaxis (20%). Conclusion Urologists may encounter patients with EO in ARM patients, frequently with positive urine culture. An appropriate urologic work-up for most ARM patients is necessary to identify and treat underlying risk factors. A practical scheme for the work-up is suggested for a close collaboration between pediatric surgeons and urologists.

Perineal Groove : An Anorectal Malformation Network, Consortium Study
- 2020
-
In: Journal of Pediatrics. - : Elsevier BV. - 0022-3476. ; 222, s. 207-212
-
Journal article (peer-reviewed)abstract
- Objective: To review the Anorectal Malformation Network experience with perineal groove (PG) focusing on its clinical characteristics and management. Study design: Data on patients with PG managed at 10 participating Anorectal Malformation Network centers in 1999-2019 were collected retrospectively by questionnaire. Results: The cohort included 66 patients (65 females) of median age 1.4 months at diagnosis. The leading referral diagnosis was anal fissure (n = 20 [30.3%]): 23 patients (34.8%) had anorectal malformations. Expectant management was practiced in 47 patients (71.2%). Eight (17%) were eventually operated for local complications. The median time to surgery was 14 months (range, 3.0-48.6 months), and the median age at surgery was 18.3 months (range, 4.8-58.0 months). In the 35 patients available for follow-up of the remaining 39 managed expectantly, 23 (65.7%) showed complete or near-complete self-epithelization by a mean age 15.3 months (range, 1-72 months) and 4 (11.4%) showed partial self-epithelization by a mean age 21 months (range, 3-48 months). Eight patients showed no resolution (5 were followed for ≤3 months). Nineteen patients (28.7%) were primarily treated with surgery. In total, 27 patients were operated. Dehiscence occurred in 3 of 27 operated patients (11.1%). Conclusions: PG seems to be an underestimated anomaly, frequently associated with anorectal malformations. Most cases heal spontaneously; therefore, expectant management is recommended. When associated with anorectal malformations requiring reconstruction, PG should be excised in conjunction with the anorectoplasty.

Bowel function and associated risk factors at preschool and early childhood age in children with anorectal malformation type rectovestibular fistula : An ARM-Net consortium study
- 2022
-
In: Journal of Pediatric Surgery. - : Elsevier BV. - 0022-3468. ; 57:9, s. 89-96
-
Journal article (peer-reviewed)abstract
- Background: Outcome of patients operated for anorectal malformation (ARM) type rectovestibular fistula (RVF) is generally considered to be good. However, large multi-center studies are scarce, mostly describing pooled outcome of different ARM-types, in adult patients. Therefore, counseling parents concerning the bowel function at early age is challenging. Aim of this study was to evaluate bowel function of RVF-patients at preschool/early childhood age and determine risk factors for poor functional outcome. Methods: A multi-center cohort study was performed. Patient characteristics, associated anomalies, sacral ratio, surgical procedures, post-reconstructive complications, one-year constipation, and Bowel Function Score (BFS) at 4–7 years of follow-up were registered. Groups with below normal (BFS < 17; subgroups ‘poor’ ≤ 11, and ‘fair’ 11 < BFS < 17) and good outcome (BFS ≥ 17) were formed. Univariable analyses were performed to detect risk factors for outcome. Results: The study included 111 RVF-patients. Median BFS was 16 (range 6–20). The ‘below normal’ group consisted of 61 patients (55.0%). Overall, we reported soiling, fecal accidents, and constipation in 64.9%, 35.1% and 70.3%, respectively. Bowel management was performed in 23.4% of patients. Risk factors for poor outcome were tethered cord and low sacral ratio, while sacral anomalies, low sacral ratio, prior enterostomy, post-reconstructive complications, and one-year constipation were for being on bowel management. Conclusions: Although median BFS at 4–7 year follow-up is nearly normal, the majority of patients suffers from some degree of soiling and constipation, and almost 25% needs bowel management. Several factors were associated with poor bowel function outcome and bowel management. Level of Evidence: Level III.
