Abstract
The widespread use of drugs for unapproved purposes remains common in children, primarily attributable to practical, ethical, and financial constraints associated with pediatric drug research. Pharmacometrics, the scientific discipline that involves the application of mathematical models to understand and quantify drug effects, holds promise in advancing pediatric pharmacotherapy by expediting drug development, extending applications, and personalizing dosing. In this review, we delineate the principles of pharmacometrics, and explore its clinical applications and prospects. The fundamental aspect of any pharmacometric analysis lies in the selection of appropriate methods for quantifying pharmacokinetics and pharmacodynamics. Population pharmacokinetic modeling is a data-driven method ('top-down' approach) to approximate population-level pharmacokinetic parameters, while identifying factors contributing to inter-individual variability. Model-informed precision dosing is increasingly used to leverage population pharmacokinetic models and patient data, to formulate individualized dosing recommendations. Physiologically based pharmacokinetic models integrate physicochemical drug properties with biological parameters ('bottom-up approach'), and is particularly valuable in situations with limited clinical data, such as early drug development, assessing drug-drug interactions, or adapting dosing for patients with specific comorbidities. The effective implementation of these complex models hinges on strong collaboration between clinicians and pharmacometricians, given the pivotal role of data availability. Promising advancements aimed at improving data availability encompass innovative techniques such as opportunistic sampling, minimally invasive sampling approaches, microdialysis, and in vitro investigations. Additionally, ongoing research efforts to enhance measurement instruments for evaluating pharmacodynamics responses, including biomarkers and clinical scoring systems, are expected to significantly bolster our capacity to understand drug effects in children.

Abstract
PURPOSE OF REVIEW Symptom burden of cancer diagnosis and treatment has led adolescents and young adult cancer patients (AYAC) and survivors to seek different self-management strategies including integrative oncology (IO) modalities. IO holds great promise to improve survivorship issues in adolescents and young adult (AYA) cancer survivors. This review aims to encompass the current evidence of IO modalities and to analyze the efficacy of IO for managing survivorship issues among AYA cancer patients and survivors. RECENT FINDINGS Nineteen randomized controlled trials included in this review evaluated mind and body modalities including both physical and psychological (74%) and psychological only (26%) modalities. Most assessed IO modalities were physical activity (PA) (37%) and structured exercise (10%). Most effective IO modalities found were PA, massage, mindfulness-based stress reduction (MBSR) and light therapy for treating AYA symptom burden. The Cochrane risk of bias (RoB-2) concluded 21% studies had high risk, 58% possessed some concerns and 21% had low risk. SUMMARY Although evidence has shown that a number of IO modalities may improve survivorship among AYA cancer survivors, more rigorous study designs are needed in order for these modalities to be routinely recommended for use in clinical practice.

Abstract
OBJECTIVE Provide clinicians with current evidence for biologic therapy in children with chronic rhinosinusitis with nasal polyposis (CRSwNP). DATA SOURCES PubMed, MEDLINE, Cochrane, and clinical trial registries. REVIEW METHODS Key search terms related to biologic therapy in pediatric CRSwNP were identified via a structured query of current medical literature and clinical trial databases. CONCLUSIONS There is a dearth of active clinical trials and research studies for biologics targeting pediatric CRSwNP. There is an ongoing compassionate-use clinical trial involving Dupilumab for children with nasal polyps as well as only 1 published work specifically focused on Dupilumab for pediatric CRSwNP in the setting of aspirin-exacerbated respiratory disease. IMPLICATIONS FOR PRACTICE For children with atopic dermatitis, asthma, and chronic idiopathic urticaria, biologic therapies such as Omalizumab, Dupilumab, and Mepolizumab have gained Food and Drug Administration approval. The role of biologic therapy in pediatric CRSwNP demonstrates significant promise in the comprehensive management of the unified airway. Additional Phase III trials are necessary to broaden clinical indications for children with comorbid conditions and complex sinonasal disease.

Abstract
The challenges of drug development in pediatric, pregnant and geriatric populations are a worldwide concern shared by regulatory authorities, pharmaceutical companies, and healthcare professionals. Model-informed drug development (MIDD) can integrate and quantify real-world data of physiology, pharmacology, and disease processes by using modeling and simulation techniques to facilitate decision-making in drug development. In this article, we reviewed current MIDD policy updates, reflected on the integrity of physiological data used for MIDD and the effects of physiological changes on the drug PK, as well as summarized current MIDD strategies and applications, so as to present the state of the art of MIDD in pediatric, pregnant and geriatric populations. Some considerations are put forth for the future improvements of MIDD including refining regulatory considerations, improving the integrity of physiological data, applying the emerging technologies, and exploring the application of MIDD in new therapies like gene therapies for special populations.

Abstract
BACKGROUND A considerable proportion of drugs administered to children are not authorised for this purpose, and consequently off-label use is common in paediatric care. Our aims were to quantify systematically the number of drugs authorised in Switzerland for use in children based on their current summary of product characteristics (SmPC) and to assess the quality of this information. METHODS We used natural language processing to screen all Swiss SmPCs, available in German language in the open-source drug database, for information about use in children. Based on the SmPCs of the most frequently used drugs in Swiss children's hospitals, 10 search terms were defined to retrieve this information. RESULTS Of the analysed 4214 drugs corresponding to 1553 active substances, 2322 (55.1%) drugs were authorised for use in children. In only 639 (15.2%) SmPCs, information about authorisation for children was found in the section 'Therapeutic indications'. 320 (13.8%) SmPCs of drugs authorised for use in children contained only verbal age indications such as 'children' and 'adolescents' without a clear definition of the age or an age range. CONCLUSIONS Most Swiss SmPCs contain information about children, but only a minority refer to an official indication. Even if some SmPCs clearly indicate that use in children is authorised, a clear statement of the age at which the drug may be administered is missing. Standardisation of information about use in children in SmPCs is needed.

Abstract
Propranolol hydrochloride, a non-cardio-selective beta blocker, is used to treat several conditions in children, including hypertension, arrhythmias, hyperthyroidism, hemangiomas, etc. Commercial liquid formulations are available in Europe and the US, but they have disadvantages, such as limited stability, bitter taste, and the need for multiple daily doses due to the drug's short half-life. Considering these limitations, controlled-release solid formulations, such as microparticles, may offer a better solution for pediatric administration. The main objective of this study was to formulate an encapsulation system for propranolol hydrochloride, based on sodium alginate and other polysaccharide polymers, to control and prolong its release. Microparticles were prepared using the ionotropic gelation method, which involves instilling a polymer solution into a solution of gelling ions via the extrusion technique. Physicochemical characterization was conducted by assessing the entrapment efficiency, drug loading, swelling index, microparticle size, rheological properties, and surface tension. In order to improve the characteristics of the tested microparticles, selected formulations were coated with chitosan. Further experimental work included differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) analysis, and SEM imaging. This in vitro release study showed that chitosan-coated microparticles demonstrate favorable properties, suggesting a novel approach to formulating pediatric dosage forms, although further optimization is necessary.

Abstract
Rare diseases have become an increasingly important public health priority due to their collective prevalence and often life-threatening nature. Incentive programs, such as the Orphan Drug Act have been introduced to increase the development of rare disease therapeutics. While the approval of these therapeutics requires supportive data from stringent pre-market studies, these data lack the ability to describe the causes of treatment response heterogeneity, leading to medications often being more harmful or less effective than predicted. If a Goal Line were to be used to describe the multifactorial continuum of phenotypic variations occurring in response to a medication, the 'Goal Posts', or the two defining points of this continuum, would be (1) Super-Response, or an extraordinary therapeutic effect; and (2) Serious Harm. Investigation of the pharmacogenomics behind these two extreme phenotypes can potentially lead to the development of new therapeutics, help inform rational use criteria in drug policy, and improve the understanding of underlying disease pathophysiology. In the context of rare diseases where cohort sizes are smaller than ideal, 'small data' and 'big data' approaches to data collection and analysis should be combined to produce the most robust results. This paper presents the importance of studying drug response in parallel to other research initiatives in rare diseases, as well as the need for international collaboration in the area of rare disease pharmacogenomics.

Abstract
Outpatient monitoring of infants with congenital heart disease has been shown to significantly reduce rates of mortality in the single ventricle population. Despite the accelerating development of miniaturized biosensors and electronics, and a growing market demand for at-home monitoring devices, the application of these technologies to infants and children is significantly delayed compared with the development of devices for adults. This article aims to review the current landscape of available monitoring technologies and devices for pediatric patients to describe the gap between technologies and clinical needs with the goal of progressing development of clinically and scientifically validated pediatric monitoring devices.

Abstract
Human challenge studies, in which human research subjects are intentionally exposed to pathogens to contribute to scientific knowledge, raise many ethical complexities. One controversial question is whether it is ethically permissible to include children as participants. Commentary of the past decades endorses the exclusion of children, while new guidance suggests that pediatric human challenge studies can be ethically permissible. This paper argues that neither children's exclusion nor their inclusion are well justified. I examine and reject three arguments for exclusion, but suggest that these arguments establish pediatric human challenge studies as a complex ethical category of research that requires caution. I then argue for a strong presumption against children's inclusion, by drawing on an analogy to children's inclusion in phase I trials, emphasizing a requirement of necessity, and suggesting that accommodating children's vulnerability promotes an age de-escalation approach for pediatric human challenge studies research. In the final section, I suggest a procedure for ethics review.

Abstract
"Children are not small adults with respect to the treatment with medicinal products." This statement of the WHO was the basis for the initiative of the European Commission for the establishment of a paediatric regulation in 2007 to improve the health of children by facilitating the development of medicines for children and adolescents. Seventeen years later, in the field of herbal medicinal products, results are still sobering. Therefore, the Foundation Plants for Health, Society for Medicinal Plants and Natural Products Research, and German Society for Phytotherapy organised a symposium to assess the status quo for the paediatric use of herbal medicinal products (HMPs), to analyse the causes of the current situation, and to discuss strategies for establishing the proof of safe and efficacious HMPs for children.The current situation for HMPs and their use in children is not fulfilling the requirements of legislation. HMPs in paediatrics are effective and safe, but considering the needs of children is necessary. In European countries, the use, registration, and marketing of HMPs are different, depending on the respective national regulations and specific traditions. EU herbal monographs are the best common denominator for such procedures. Emerging safety discussions must be considered. New approaches with real-world data might be a solution. The regulatory framework is to be adapted. Defining rationalised dosing for HMPs can be achieved by the extrapolation of data from adults, by using existing clinical data for children, and by using RWD. Therefore, a strong need for revising restrictions for the use of HMPs in children and rationalising defined dosage regimes is obvious.

Abstract
Children were often referred to as "therapeutic orphans" in the past due to different reasons such as ethical, regulatory, economic, scientific, etc., ones. They were exposed to avoidable risks while missing out on therapeutic advances. Pediatric patients have suffered from a lack of scientific and regulatory standards (e.g., proper drug testing, authorization of medicines for their use, etc.), although the pharmaceutical legislative framework, which ensures the high standards of safety, quality, and efficacy of medicinal products for use in adults, was developed primarily in response to past "drug disasters," mainly involving children. The adoption of pediatric regulatory initiatives first in the USA and then in Europe and other countries and regions has significantly changed the worldwide frameworks and permanently changed pediatric drug research and development. This article tries to give various perspectives with historical context, a review of the different challenges and opportunities as well as important stakeholders in pediatric drug development. The pediatric trial networks are probably the most important stakeholder that enables efficient patient recruitment, access to better resource utilization, and global collaboration of different stakeholders necessary for performing quality and well-designed clinical trials.

Spontaneous recovery from neuromuscular block after a single dose of a muscle relaxant in pediatric patients: A systematic review using a network meta-analytic and meta-regression approach. Paediatr Anaesth 2024. [PMID: 38676354 DOI: 10.1111/pan.14908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 04/12/2024] [Accepted: 04/13/2024] [Indexed: 04/28/2024]
Abstract
BACKGROUND Age-related differences in the pharmacokinetics and pharmacodynamics of neuromuscular blocking agents (NMBAs) and the short duration of many surgical procedures put pediatric patients at risk of postoperative residual curarization (PORC). To date, the duration of neuromuscular blocking agent effect in children has not been analyzed in a quantitative review. The current meta-analysis aimed to compare spontaneous recovery following administration of various types and doses of neuromuscular blocking agents and to quantify the effect of prognostic variables associated with the recovery time in pediatric patients. METHOD We searched for randomized controlled trials (RCTs) and controlled clinical trials (CCTs) that compared the time to 25% T1 (t25), from 25% to 75% T1 (RI25-75), and to ≥90% train-of-four (tTOF90) neuromuscular recovery between common neuromuscular blocking agent treatments administered as a single bolus to healthy pediatric participants. We compared spontaneous t25, RI25-75, and tTOF90 between (1) neuromuscular blocking agent treatments and (2) age groups receiving a given neuromuscular blocking agent intervention and anesthesia technique. Bayesian random-effects network and pairwise meta-analyses along with meta-regression were used to evaluate the results. RESULTS We used data from 71 randomized controlled trials/controlled clinical trials including 4319 participants. Network meta-analysis allowed for the juxtaposition and ranking of spontaneous t25, RI25-75, and tTOF90 following common neuromuscular blocking agent interventions. For all neuromuscular blocking agents a log-linear relationship between dose and duration of action was found. With the neuromuscular blocking agent treatments studied, the average tTOF90 (mean[CrI95]) in children (>2-11 y) was 41.96 [14.35, 69.50] and 17.06 [5.99, 28.30] min shorter than in neonates (<28 d) and infants (28 d-12 M), respectively. We found a negative log-linear correlation between age and duration of neuromuscular blocking agent effect. The difference in the tTOF90 (mean[CrI95]) between children and other age groups increased by 21.66 [8.82, 34.53] min with the use of aminosteroid neuromuscular blocking agents and by 24.73 [7.92, 41.43] min with the addition of sevoflurane/isoflurane for anesthesia maintenance. CONCLUSIONS The times to neuromuscular recovery are highly variable. These can decrease significantly with age and are prolonged when volatile anesthetics are administered. This variability, combined with the short duration of many pediatric surgical procedures, makes quantitative neuromuscular monitoring mandatory even after a single dose of neuromuscular blocking agent.

Abstract
Language disorders may interfere with social integration and affectpersonal development. Beca-use the balance of the stomatognathic system can interfere with language, it is important for speech therapy and dentistry to work together, providing multidisciplinar y Healthcare. AIM To analyze the 100 most frequently cited articles on language disorders in children and adolescents and assess the interplay with dentistry by means of a bibliometric analysis. MATERIALS AND METHOD A search of the 100 most frequently cited articles up to December 2021 on language disorders was performed in the Web of Science Core Collection database. Four researchers extracted the data on number of citations, title, authors, country, year of publication, journals, study design, prevalent clinical conditions, and area of expertise. The analyses were performed using VOSviewer and Excel. RESULTS The total number of citations ranged from 251 to 1,431. Four articles were cited more than 1,000 times. Bishop DVM (10 articles; 3,653 citations) and Tomblin JD (10 articles; 4,261 citations) were the most frequently cited authors. The institutions with the largest number of publications were the University of Oxford/England (11%) and the University of Kansas/USA (8%). Observational study design was the most frequent (77%). Autism spectrum disorder (18%) and dyslexia (14%) were the most broadly investigated clinical conditions. Speech-language pathology (32%) was the area of expertise with the largest number of articles, and none of the top 100 studies showed interplay with dentistry. CONCLUSION The 100 most widely cited articles on language disorders are mostly observational, mainly address autism spectrum disorder, and are in the field of speech-language pathology No study reported interplay with dentistry.

Abstract
BACKGROUND The evidence of treatment options' efficacy on acute bipolar manic episodes is relatively less in youths than adults. We aimed to compare and rank the drug's efficacy, acceptability, tolerability, and safety for acute mania in children and adolescents. METHOD We systematically reviewed the double-blinded, randomized controlled trials (RCTs) comparing drugs or placebo for acute manic episodes of bipolar disorder in children and adolescents using PRISMA guidelines. We searched PubMed/MEDLINE, EMBASE, Web of Science, EBSCO, Scopus, the Cochrane Central Register of Controlled Trials, and https://clinicaltrials.gov from inception until November 20, 2022. Response to treatment was the primary outcome, and random-effects network meta-analyses were conducted (PROSPERO 2022: CRD42022367455). RESULTS Of 10,134 citations, we included 15 RCTs, including 2372 patients (47 % female), 15 psychotropic drugs, and the placebo. Risperidone 0.5-2.5 mg/day, aripiprazole 30 mg/day olanzapine, quetiapine 400 mg/day, quetiapine 600 mg/day, asenapine 5 mg/day, asenapine 10 mg, ziprasidone, and aripiprazole 10 mg were found to be effective (in comparison with placebo) in children and adolescents, respectively (τ2 = 0.0072, I2 = 10.2 %). The tolerability of aripiprazole 30 mg/day was lower than risperidone 0.5-2.5 mg/day and olanzapine. Oxcarbazepine had the highest discontinuation due to the adverse effects risk ratio. LIMITATIONS Efficacy ranking of the treatments could be performed by evaluating relatively few RCT results, and only monotherapies were considered. CONCLUSIONS Efficacy, acceptability, tolerability, and safety are changing with the doses of antipsychotics for children and adolescents with acute bipolar manic episodes. Drug selection and optimum dosage should be carefully adjusted in children and adolescents.

Abstract
When planning paediatric trials, it is important to consider how best to communicate with children and young people (CYP) so they understand what they are taking part in. It is also important to consider what information they need. Involving CYP as research participants leads to research that is more relevant although it can be difficult to engage CYP in qualitative research to improve trial materials due to the topic area. This paper describes how a visual ranking exercise within qualitative interviews acted as a helpful conduit to engaging discussions to inform a co-designed website with information for trial participants. 40 people participated in interviews during which the ranking exercise was used (11 CYP aged 9-18 years, 14 parents, 15 professionals). We found the ranking exercise supported participant engagement and prevented them feeling that particular responses were expected. It also enabled participants to discuss their ranking (and decisions behind this) with other participants and the researcher. Co-design interviews with CYP that use interactive exercises such as ranking are likely to elicit richer data than those relying on traditional questioning techniques.

Abstract
Importance Pediatric medication is a challenging issue globally. Promoting trials of medications for children and implementing measures to encourage innovation for addressing unmet medical and health needs are important. Objective To explore the recent landscape of pediatric clinical trials of new investigational drugs conducted by pharmaceutical enterprises in China from 2013 to 2022 to provide insight into pediatric drug development in the pharmaceutical industry and regulatory policy formulation. Methods We performed a cross-sectional observational investigation of pediatric clinical trials registered from January 1, 2013, to December 31, 2022, on the Registration and Information Disclosure Platform for Drug Clinical Trials, the official registration platform established in 2013 for trials of new investigational drugs initiated by biopharmaceutical enterprises. Trials that included pediatric participants (under 18 years old) were retrieved, and their relevant characteristics were extracted and analyzed. Results In total, 895 pediatric clinical trials were collected, accounting for 5.1% of the total registered clinical trials initiated prior to January 1, 2023. The overall average annual growth rate for the number of pediatric clinical trials was 12% (P < 0.001). Phase III trials accounted for the highest proportion (49.1%, 439). Of the 895 trials included, 736 (82.2%) were domestic trials, and 159 (17.8%) were international multicenter trials. In terms of tested drugs, investigations of biological products accounted for the largest proportion of trials (67.4%, 603). Among pediatric clinical trials, studies of vaccines accounted for the largest proportion of trials (41.0%, 367), followed by trials for rare diseases (17.2%, 154). Furthermore, geographical distribution analysis revealed that the largest and smallest numbers of trials were conducted in North China (35.7%, 320) and Northeast China (0.8%, 7), respectively. Interpretation The growth trends for industry-sponsored clinical trials involving children illustrate the progress and increasing capability of pediatric drug development achieved in China since 2013. Current challenges and potential areas of focus for policymakers and stakeholders include investigating orphan drugs for rare diseases according to the unique epidemiological characteristics of Chinese children, expanding the scope of pediatric clinical trials, and improving the uneven geographical distribution of leading research centers.

Abstract
OBJECTIVE To identify practices that add value to improve the design, conduct, and reporting of child health research and reduce research waste. STUDY DESIGN In order to categorize the contributions of members of Standards for Research (StaR) in Child Health network, we developed a novel Child Health Improving Research Practices (CHIRP) framework comprised of 5 domains meant to counteract avoidable child health research waste and improve quality: 1) address research questions relevant to children, their families, clinicians, and researchers; 2) apply appropriate research design, conduct and analysis; 3) ensure efficient research oversight and regulation; 4) Provide accessible research protocols and reports; and 5) develop unbiased and usable research reports, including 17 responsible research practice recommendations. All child health research relevant publications by the 48 original StaR standards' authors over the last decade were identified, and main topic areas were categorized using this framework. RESULTS A total of 247 publications were included in the final sample: 100 publications (41%) in domain 1 (3 recommendations), 77 publications (31%) in domain 2 (3), 35 publications (14%) in domain 3 (4), 20 publications (8%) in domain 4 (4), and 15 publications (6%) in domain 5 (3). We identified readily implementable "responsible" research practices to counter child health research waste and improve quality, especially in the areas of patients and families' engagement throughout the research process, developing Core Outcome Sets, and addressing ethics and regulatory oversight issues. CONCLUSION While most of the practices are readily implementable, increased awareness of methodological issues and wider guideline uptake is needed to improve child health research. The CHIRP Framework can be used to guide responsible research practices that add value to child health research.

Abstract
Research involving pediatric populations has important ethical and regulatory considerations. As children generally cannot consent to research, there are special protections put in place to ensure that the decisional vulnerability is protected, including parental permission and often the child's assent. Assent is an ethically important part of the research because it allows the child to participate in the process of agreeing to research, develop their autonomy, and express their values. This article explores a case where the child and parent disagree about the child's participation. In doing so, the regulatory requirements of pediatric research are outlined and the process and product of obtaining assent from a minor is described.

Abstract
Paediatric clinical trials are critical to ensure that medications prescribed to children are safe and effective. However, evidence-based dosing and labelling of such medications remain limited, and most clinical trials in paediatrics fail. Factors for lack of trial completion include performance at site level (limited patient recruitment, limited site staff experience and lack of infrastructure), the sponsor team (limited paediatric specific expertise in design, uncertainties on robustness of biomarkers or outcome variables) as well as regulatory and administrative burdens. As a result of the growing demand for site support, the Belgian Paediatric Clinical Research Network (BPCRN) established in 2009 has been relaunched in 2018 to improve paediatric clinical trials, with the support of innovative-medicines-initiative 2 (IMI2) pan-European network conect4children (c4c) and the transatlantic network I-ACT for Children (US).This paper highlights the formation of the BPCRN and the practical insights it offers for advancing paediatric clinical trials through national networks. A national network can improve trial quality, safety and efficiency, provide clinical research expertise, identify suitable sites, and help with troubleshooting of common trial issues. The BPCRN's centralized approach has advanced paediatric clinical trials by streamlining communication and standardizing trial conduct. Challenges and opportunities have arisen, including a relaunch in 2018, orphan medicine trials, and network sustainability. Collaboration between network activities, government support, site-level improvements, efficient communication, and interaction with industry are key to achieve lasting transformation in paediatric medicine research.

[PMID: 38255096 PMCID: PMC10815156 DOI: 10.3390/healthcare12020208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/23/2023] [Accepted: 01/11/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND Unlicensed and off-label (UL/OL) prescriptions have been associated with an increased risk of drug-related problems. Data of their prevalence at hospital discharge remain insufficient. We aimed to describe the prevalence of UL/OL drugs in outpatient prescriptions at discharge in children. METHODS We conducted a retrospective study using the routinely collected health data of children at discharge from 2014 to 2016. The primary reference source for determining licensed labelling was the summaries of product characteristics (SPCs) in a French industry-independent formulary named Thériaque. We described the characteristics of UL/OL prescriptions at discharge and looked for predictors of UL/OL prescriptions. RESULTS We included 2536 prescriptions of 479 children. Licensed, OL, and UL prescriptions accounted for 58.6% (95% CI: 56.7-60.5), 39.2% (95% CI: 37.3-41.1), and 2.3% (95% CI: 1.7-2.9), respectively. A total of 323 (74%) children received at least one UL/OL drug. Among the licensed drugs, bronchodilators (8.8%) and analgesics (8.6%), and among the OL drugs, antibiotics (2.8%), were the most prescribed. The younger age of the children and higher number of drugs they received increased the probability of UL/OL prescriptions (unadjusted p-value of ≤0.05). CONCLUSION The prevalence of UL/OL prescriptions is about 40% at discharge from a pediatric university hospital in France.

Abstract
OBJECTIVE This study examined the application, feasibility, and validity of supervised learning models for text classification in appraisals for rare disease treatments (RDTs) in relation to uncertainty, and analyzed differences between appraisals based on the classification results. METHODS We analyzed appraisals for RDTs (n = 94) published by the National Institute for Health and Care Excellence (NICE) between January 2011 and May 2023. We used Naïve Bayes, Lasso, and Support Vector Machine models in a binary text classification task (classifying paragraphs as either referencing uncertainty in the evidence base or not). To illustrate the results, we tested hypotheses in relation to the appraisal guidance, advanced therapy medicinal product (ATMP) status, disease area, and age group. RESULTS The best performing (Lasso) model achieved 83.6 percent classification accuracy (sensitivity = 74.4 percent, specificity = 92.6 percent). Paragraphs classified as referencing uncertainty were significantly more likely to arise in highly specialized technology (HST) appraisals compared to appraisals from the technology appraisal (TA) guidance (adjusted odds ratio = 1.44, 95 percent CI 1.09, 1.90, p = 0.004). There was no significant association between paragraphs classified as referencing uncertainty and appraisals for ATMPs, non-oncology RDTs, and RDTs indicated for children only or adults and children. These results were robust to the threshold value used for classifying paragraphs but were sensitive to the choice of classification model. CONCLUSION Using supervised learning models for text classification in NICE appraisals for RDTs is feasible, but the results of downstream analyses may be sensitive to the choice of classification model.

Abstract
Improving the treatment of non-cystic fibrosis bronchiectasis in children and adolescents requires high-quality research with outcomes that meet study objectives and are meaningful for patients and their parents and caregivers. In the absence of systematic reviews or agreement on the health outcomes that should be measured in paediatric bronchiectasis, we established an international, multidisciplinary panel of experts to develop a core outcome set (COS) that incorporates patient and parent perspectives. We undertook a systematic review from which a list of 21 outcomes was constructed; these outcomes were used to inform the development of separate surveys for ranking by parents and patients and by health-care professionals. 562 participants (201 parents and patients from 17 countries, 361 health-care professionals from 58 countries) completed the surveys. Following two consensus meetings, agreement was reached on a ten-item COS with five outcomes that were deemed to be essential: quality of life, symptoms, exacerbation frequency, non-scheduled health-care visits, and hospitalisations. Use of this international consensus-based COS will ensure that studies have consistent, patient-focused outcomes, facilitating research worldwide and, in turn, the development of evidence-based guidelines for improved clinical care and outcomes. Further research is needed to develop validated, accessible measurement instruments for several of the outcomes in this COS.

Abstract
Off-label prescription in paediatric patients is common, where some studies indicate that dermatological conditions are more prone to off-label treatment. This is the first study to analyse the prevalence of off-label prescription in paediatric dermatology consultation. This retrospective observational study was performed using the medical records of paediatric patients who were evaluated in a paediatric dermatological consultation in Pontevedra University Hospital, Pontevedra, Spain. Of the 468 patients reviewed, 186 prescriptions were issued and 51.10% were off-label prescription drugs. The dermatological conditions for which off-label prescription was most common were atopic dermatitis (29.0%), followed by warts (12.9%) and infantile haemangiomas (11.8%). With respect to drugs, topical tacrolimus (23.7%) was the most frequently prescribed off-label drug. The main reason for prescribing an off-label drug was for a disease not included on the label (62.4%), followed by issuing it at a lower age than authorized (55.9%). There was a significant association between a higher percentage of off-label prescription and younger age (p < 0.001), and the treatment of vitiligo, infantile haemangiomas and warts (p < 0.001). Likewise, the off-label prescription was significantly more common in the case of topical terbinafine, timolol, desloratadine and topical salicylic acid (p < 0.001). To conclude, off-label prescription is predominant in paediatric dermatology, as observed in 51.1% of our patients.

Abstract
Lack of access to pediatric medical devices and innovative technology contributes to global disparities in children's surgical care. There are currently many barriers that prevent access to these technologies in low- and middle-income countries (LMICs). Technologies that were designed for the needs of high-income countries (HICs) may not fit the resources available in LMICs. Likewise, obtaining these devices are costly and require supply chain infrastructure. Once these technologies have reached the LMIC, there are many issues with sustainability and maintenance of the devices. Ideally, devices would be created for the needs and resources of LMICs, but there are many obstacles to innovation that are imposed by institutions in both HICs and LMICs. Fortunately, there is a growing interest for development of this space, and there are many examples of current technologies that are paving the way for future innovations. Innovations in simulation-based training with incorporated learner self-assessment are needed to fast-track skills acquisition for both specialist trainees and non-specialist children's surgery providers, to scale up access for the larger population of children. Pediatric laparoscopy and imaging are some of the innovations that could make a major impact in children's surgery worldwide.

Abstract
Off-label prescribing is widespread among pediatricians, and it is unlikely that this trend will soon be bound by a uniform legal framework. This is necessitated by the fact that there are four variables: the patient's health condition, the physician's experience and knowledge, the legislative measures (laws, directives, guidelines, and recommendations), and finally, the pharmaceutical industry. There is considerable concern worldwide about the use of off-label medicines in children. We may call it an enormous global problem that is much talked about and written about; however, we should not forget that the goal around which everyone should unite is the patient's life. For healthcare providers, the most important thing will always be the health and preservation of the patient's life, particularly when it comes to children with life-threatening conditions in neonatal and pediatric intensive care units (NICU and PICU). The study aimed to examine the prevalence of off-label drug use in pediatrics. Literature research was conducted, and we included studies from 2012 to 2022 that evaluated off-label drug prevalence in various pediatric patient populations.

Abstract
To investigate the gut microbiota distribution and its functions in children with avoidant/restrictive food intake disorder (ARFID). A total of 135 children were enrolled in the study, including 102 children with ARFID and 33 healthy children. Fecal samples were analyzed to explore differences in gut microbiota composition and diversity and functional differences between the ARFID and healthy control (HC) groups via 16S rDNA and metagenomic sequencing. The gut microbiota composition and diversity in children with ARFID were different from those in heathy children, but there is no difference in the composition and diversity of gut microbiota between children at the age of 3-6 and 7-12 with ARFID. At the phylum level, the most abundant microbes in the two groups identified by 16S rDNA and metagenomic sequencing were the same. At the genus level, the abundance of Bacteroides was higher in the ARFID group (P > 0.05); however, different from the result of 16SrDNA sequencing, metagenomic sequencing showed that the abundance of Bacteroides in the ARFID group was significantly higher than that in the HC group (P = 0.041). At the species level, Escherichia coli, Streptococcus thermophilus and Lachnospira eligens were the most abundant taxa in the ARFID group, and Prevotella copri, Bifidobacterium pseudocatenulatum, and Ruminococcus gnavus were the top three microbial taxa in the HC group; there were no statistically significant differences between the abundance of these microbial taxa in the two groups. LefSe analysis indicated a greater abundance of the order Enterobacterales and its corresponding family Enterobacteriaceae, the family Bacteroidaceae and corresponding genus Bacteroides, the species Bacteroides vulgatus in ARFID group, while the abundance of the phylum Actinobacteriota and its corresponding class Actinobacteria , the order Bifidobacteriales and corresponding family Bifidobacteriaceae, the genus Bifidobacterium were enriched in the HC group. There were no statistically significant differences in the Chao1, Shannon and Simpson indices between the Y1 and Y2 groups (P = 0.1, P = 0.06, P = 0.06). At the phylum level, Bacillota, Bacteroidota, Proteobacteria and Actinobacteriota were the most abundant taxa in both groups, but there were no statistically significant differences among the abundance of these bacteria (P = 0.958, P = 0.456, P = 0.473, P = 0.065). At the genus level, Faecalibacterium was more abundant in the Y2 group than in the Y1 group, and the difference was statistically significant (P = 0.037). The KEGG annotation results showed no significant difference in gut microbiota function between children with ARFID and healthy children; however, GT26 was significantly enriched in children with ARFID based on the CAZy database. The most abundant antibiotic resistance genes in the ARFID group were the vanT, tetQ, adeF, ermF genes, and the abundance of macrolide resistance genes in the ARFID group was significantly higher than that in the HC group (P = 0.041). Compared with healthy children, children with ARFID have a different distribution of the gut microbiota and functional genes. This indicates that the gut microbiome might play an important role in the pathogenesis of ARFID.Clinical trial registration: ChiCTR2300074759.

Abstract
Due to the customary delay between medication approvals in adult and adolescent populations, adolescents with schizophrenia may receive off-label antipsychotic treatment, without empirically justified dosing recommendations. In order to accelerate pediatric drug development, the US Food and Drug Administration (FDA) released a general advice letter to sponsors permitting the effectiveness of atypical antipsychotics for the treatment of schizophrenia in adults to be extrapolated to adolescents based on a pharmacokinetic (PK) analysis to support dose selection, plus a safety study. The aim of the present article is to describe the population PK analysis that was submitted to the FDA to inform brexpiprazole dose selection in adolescents with schizophrenia. Using a population PK model with brexpiprazole clearance and volume of distribution allometrically scaled by body weight, PK simulations showed comparable brexpiprazole dose-exposure between adults and adolescents aged 13-17 years following oral daily doses of brexpiprazole 1-4 mg, indicating that the target brexpiprazole dose of 2-4 mg/day in adults with schizophrenia is also suitable for adolescents. Based on this population PK analysis, together with a safety study in adolescents, the FDA approved brexpiprazole for the treatment of schizophrenia in adolescents aged 13-17 years, via extrapolation of the efficacy of brexpiprazole from adults to adolescents.

Abstract
Background The information provided to potential trial participants plays a crucial role in their decision-making. Printed participant information sheets for trials have received recurrent criticism as being too long and technical, unappealing and hard to navigate. An alternative is to provide information through multimedia (text, animations, video, audio, diagrams and photos). However, there is limited evidence on the effects of multimedia participant information on research recruitment rates, particularly in children and young people. Objectives The study objectives were as follows: 1. to develop template multimedia information resources through participatory design, for use when recruiting children and young people to trials 2. to evaluate the multimedia information resources in a series of Studies Within A Trial, to test their effects on recruitment and retention rates, and participant decision-making, by comparing the provision of multimedia information resources instead of printed participant information sheets, and comparing the provision of multimedia information resources in addition to printed participant information sheets. Design Two-phase study: 1. multimedia information resources development including qualitative study; user testing study; readability metrics; enhanced patient and public involvement 2. multimedia information resources' evaluation comprising Studies Within A Trial undertaken within host trials recruiting children and young people. Setting United Kingdom trials involving patients aged under 18. Participants Development phase: n = 120 (children and young people, parents, clinicians, trial personnel). Evaluation phase: n = 1906 (children and young people being asked to take part in trials). Interventions Multimedia information resources (comprising text, audio, 'talking heads' video, trial-specific and trial-generic animations). Printed participant information sheets. Main outcome measures Primary outcome: trial recruitment rate comparing multimedia information resource-only with printed participant information sheet-only provision. Secondary outcomes: trial recruitment rate comparing combined multimedia information resource and printed participant information sheet with printed participant information sheet-only provision; trial retention rate; quality of participant decision-making. Results for each trial were calculated and combined in a two-stage random-effects meta-analysis. Results Phase 1 generated two multimedia information resource templates: (1) for children aged 6-11 years; (2) for children aged 12-18 years and parents. In the Phase 2 Studies Within A Trial the multimedia information resources improved trial recruitment, when compared to printed information alone [odds ratio (OR) = 1.54; 95% confidence interval (CI) 1.05 to 2.28; p = 0.03; I2 = 0%]. When printed participant information sheet-only provision was compared to combined multimedia information resource and printed participant information sheet provision, there was no effect on trial recruitment (OR = 0.89; 95% CI 0.53 to 1.50; I2 = 0%). There were no differences between multimedia information resource and printed participant information sheet on trial retention or participant decision-making quality. In a study within a hypothetical trial setting, multimedia information resource-only provision produced higher ratings of 'information was easy to understand' (Z = 3.03; p = 0.003) and 'I had confidence in decision-making' (Z = 2.00; p = 0.044) than printed participant information sheet-only provision. Limitations It was not possible to include data from three Studies Within A Trial in the meta-analysis due to limited sample size, and questionnaire return rates were low, which reduced the strength of the findings. Conclusions Use of multimedia information increased the rate of recruitment to trials involving children and young people compared to standard patient information sheets. Future work There should be further evaluation of the effects of multimedia information on recruitment to trials involving children and young people. It would be valuable to assess any impacts of multimedia information resources on communication between trial recruiters, children and young people, and parents.

Abstract
The paradigm of pediatric drug development has been evolving in a "carrot-and-stick"-based tactic to address population-specific issues. However, the off-label prescription of adult medicines to pediatric patients remains a feature of clinical practice, which may compromise the age-appropriate evaluation of treatments. Therefore, the United States and the European Pediatric Formulation Initiative have recommended applying nanotechnology-based delivery systems to tackle some of these challenges, particularly applying inorganic, polymeric, and lipid-based nanoparticles. Connected with these, advanced therapy medicinal products (ATMPs) have also been highlighted, with optimistic perspectives for the pediatric population. Despite the results achieved using these innovative therapies, a workforce that congregates pediatric patients and/or caregivers, healthcare stakeholders, drug developers, and physicians continues to be of utmost relevance to promote standardized guidelines for pediatric drug development, enabling a fast lab-to-clinical translation. Therefore, taking into consideration the significance of this topic, this work aims to compile the current landscape of pediatric drug development by (1) outlining the historic regulatory panorama, (2) summarizing the challenges in the development of pediatric drug formulation, and (3) delineating the advantages/disadvantages of using innovative approaches, such as nanomedicines and ATMPs in pediatrics. Moreover, some attention will be given to the role of pharmaceutical technologists and developers in conceiving pediatric medicines.

Abstract
Levetiracetam (Lev) is an antiepileptic drug that has been increasingly used in the epilepsy pediatric population in recent years, but its pharmacokinetic behavior in pediatric population needs to be characterized clearly. Clinical trials for the pediatric drug remain difficult to conduct due to ethical and practical factors. The purpose of this study was to use the physiologically based pharmacokinetic (PBPK) model to predict changes in plasma exposure of Lev in pediatric patients and to provide recommendations for dose adjustment. A PBPK model of Lev in adults was developed using PK-Sim® software and extrapolated to the entire age range of the pediatric population. The model was evaluated using clinical pharmacokinetic data. The results showed the good fit between predictions and observations of the adult and pediatric models. The recommended doses for neonates, infants and children are 0.78, 1.67 and 1.22 times that of adults, respectively. Moreover, at the same dose, plasma exposure in adolescents was similar to that of adults. The PBPK models of Lev for adults and pediatrics were successfully developed and validated to provide a reference for the rational administration of drugs in the pediatric population.

Abstract
Background High-quality, efficient, pharmacokinetic (PK), pharmacodynamic (PD), and safety studies in children are needed. Point-of-care trials in adults have facilitated clinical trial participation for patients and providers, minimized the disruption of clinical workflow, and capitalized on routine data collection. The feasibility and value of point-of-care trials to study PK/PD in children are unknown, but appear promising. The Opportunistic PK/PD Trial in Critically Ill Children with Heart Disease (OPTIC) is a programmatic point-of-care approach to PK/PD trials in critically ill children that seeks to overcome barriers of traditional pediatric PK/PD studies to generate safety, efficacy, PK, and PD data across multiple medications, ages, and disease processes. Methods This prospective, open-label, non-randomized point-of-care trial will characterize the PK/PD and safety of multiple drugs given per routine care to critically ill children with heart disease using opportunistic and scavenged biospecimen samples and data collected from the electronic health record. OPTIC has one informed consent form with drug-specific appendices, streamlining study structure and institutional review board approval. OPTIC capitalizes on routine data collection through multiple data sources that automatically capture demographics, medications, laboratory values, vital signs, flowsheets, and other clinical data. This innovative automatic data collection minimizes the burden of data collection and facilitates trial conduct. Data will be validated across sources to ensure accuracy of dataset variables. Discussion OPTIC's point-of-care trial design and automated data acquisition via the electronic health record may provide a mechanism for conducting minimal risk, minimal burden, high efficiency trials and support drug development in historically understudied patient populations.

Abstract
OBJECTIVES In this matched cohort study using data from pediatric hospitals, we compared the incidence of hospital-acquired conditions (HACs) during clinical research hospitalizations to nonresearch hospitalizations. METHODS Using Pediatric Health Information System data for inpatient discharges January 2017-June 2022, we matched research hospitalizations (identified by International Classification of Diseases, Tenth Revision, diagnosis code) to nonresearch hospitalizations within hospital on age (±3 y), sex, discharge year (±2), and All Patients Refined Diagnosis Related Groups classification, severity of illness (±1), and risk of mortality (±1). We calculated the incidence (per 1000 discharges) and incidence rate (per 10,000 patient days) of HAC identified by International Classification of Diseases, Tenth Revision, codes and compare research versus nonresearch using logistic and Poisson regression, accounting for matching using generalized estimating equations and adjusting for sociodemographic factors and hospital utilization. RESULTS We matched 7000 research hospitalizations to 26,447 nonresearch from 28 hospitals. Median age was 6.0 years (interquartile range, 10.6 y). Median length of stay was 4.0 days (interquartile range, 11.0 days) with longer stays among research hospitalizations ( P < 0.001). Incidence of HAC among research hospitalizations was 13.1 versus 7.2 per 1000 for nonresearch ( P < 0.001) and incidence rate 6.7 versus 4.5 per 10,000 patient days. Adjusting for sociodemographic and clinical factors, research stays had 1.65 times the odds of any HAC (95% confidence interval, 1.27-2.16; P < 0.001) and 1.38 times the incidence rate (95% confidence interval, 1.09-1.75; P = 0.009). CONCLUSIONS Our findings indicate that pediatric research hospitalizations are more likely to experience HACs compared with nonresearch hospitalizations. These findings have important safety implications for pediatric inpatient clinical research that warrant further study.

Diversity and Representation Among United States Participants in Amgen Clinical Trials. J Racial Ethn Health Disparities 2023:10.1007/s40615-023-01768-2. [PMID: 37755687 DOI: 10.1007/s40615-023-01768-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 08/17/2023] [Accepted: 08/18/2023] [Indexed: 09/28/2023]
Abstract
OBJECTIVE Describe the demographic profile of US participants in Amgen clinical trials over a 10-year period and variations across therapeutic areas, indications, and geographies. METHODS Cross-sectional retrospective study including participants enrolled (2005-2020) in phase 1-3 trials completed between January 1, 2012 and June 30, 2021. RESULTS Among 31,619 participants enrolled across 258 trials, one-fifth represented racial minority populations (Asian, 3%; Black or African American, 17%; American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, multiracial, each < 1%); fewer than one-fifth (16%) represented an ethnic minority population (Hispanic or Latino). Compared with census data, representation of racial and ethnic groups varied across US states. Across most therapeutic areas (bone, cardiovascular, hematology/oncology, inflammation, metabolic disorders, neuroscience) except nephrology, participants were predominantly White (72-81%). A similar proportion of males and females were enrolled between 2005 and 2016; male representation was disproportionately higher than female between 2016 and 2020. Across most medical indications, the majority of participants were 18-65 years of age. CONCLUSIONS AND RELEVANCE While the clinical research community is striving to achieve diversity and proportional representation across clinical trials, certain populations remain underrepresented. Our data provide a baseline assessment of the diversity and representation of US participants in Amgen-sponsored clinical trials and add to a growing body of evidence on the importance of diversity in clinical research. These data provide a foundation for strategies aimed at supporting more equitable and representative research, and a baseline from which to assess the impact of future strategies to advance health equity.

Abstract
Introduction Incorporating real-world data using "big data" analysis in healthcare are useful to extract specific information for healthcare delivery system improvement. All-cause mortality is an essential measure to enhance patient safety in clinical trial research, especially for underrepresented pediatric participants. Objective This study aimed to determine the associations between pediatric mortality and patient-specific factors using the Healthcare Cost and Utilization Project (HCUP) database. Methods Data from the 2019 the HCUP Kids' Inpatient Database (KID) were used to conduct a logistic regression analysis to determine associations between pediatric patients' the chance of survival and their demographic and socioeconomic background, discharge records, and hospital information. Results Total number of diagnoses (OR = 0.84), total number of procedures (OR = 0.86), length of stay (OR = 1.04), age intervals greater than 1 year (OR > 1.0), transfer into the hospital from a different acute care (OR = 0.34), major diagnoses of multiple significant trauma (OR = 0.03) or hepatobiliary system and pancreas (OR = 0.10), region of hospital - west and midwest (OR > 1.0), and medium or larger hospital bed size (OR > 1.0) were all significantly associated with the chance of survival for patients participating in pediatric clinical trials (p < 0.05). Conclusion Real-world clinical trial data analysis showed the potential improvement area including reallocating trial resources to promote trial quality and safe participation for pediatric patients. Pediatric trials need tools that are developed using user-centered design approaches to satisfy the unique needs and requirements of pediatric patients and their caregivers. Safe intrahospital transfer procedures and active dissemination of successful trial best practices are crucial to trial management, adherence, quality, and safety.

Abstract
PURPOSE To synthesize the outcome measures used by randomized controlled trials (RCTs) for childhood glaucoma. METHODS MEDLINE, EMBASE, and Scopus were searched from inception to February 17, 2023. Randomized controlled trials and observational studies related to childhood glaucoma were included. Primary and secondary outcomes were extracted and the data was used to generate a literature review. RESULTS This review identified 42 unique reports pertaining to childhood glaucomas. Most of the studies originated from Egypt, India, and the USA. Intraocular pressure (IOP) outcomes were the most frequent outcomes studied, followed by clinical outcomes and safety outcomes. Clinical outcomes were the most common secondary outcomes studied, followed by IOP outcomes and safety outcomes. CONCLUSIONS This systematic review found heterogenous outcomes with IOP outcomes as the most studied primary outcome. As the remaining outcomes were not consistently utilized, this review highlights the need for a consensus on studies of pediatric glaucoma.

Abstract
BACKGROUND The World Health Organization declared the COVID-19 pandemic on 11 March 2020. Vaccine development and deployment were swiftly prioritised as a method to manage and control disease spread. The development of an effective vaccine relies on people's participation in randomised trials. Recruitment to vaccine trials is particularly challenging as it involves healthy volunteers who may have concerns around the potential risks and benefits associated with rapidly developed vaccines. OBJECTIVES To explore the factors that influence a person's decision to participate in a vaccine trial in the context of a pandemic or epidemic. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was June 2021. SELECTION CRITERIA We included qualitative studies and mixed-methods studies with an identifiable qualitative component. We included studies that explored the perspectives of adults aged 18 years or older who were invited to take part in vaccine trials in the context of a pandemic or epidemic. DATA COLLECTION AND ANALYSIS We assessed the title, abstracts and full texts identified by the search. We used a sampling frame to identify data-rich studies that represented a range of diseases and geographical spread. We used QSR NVivo to manage extracted data. We assessed methodological limitations using an adapted version of the Critical Skills Appraisal Programme (CASP) tool for qualitative studies. We used the 'best-fit framework approach' to analyse and synthesise the evidence from our included studies. We then used the Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) assessment to assess our confidence in each finding and develop implications for practice. MAIN RESULTS We included 34 studies in our review. Most studies related to HIV vaccine trials. The other studies related to Ebola virus, tuberculosis, Zika virus and COVID-19. We developed 20 key findings, under three broad themes (with seven subthemes), that described the factors that people consider when deciding whether to take part in a vaccine trial for a pandemic or epidemic disease. Our GRADE-CERQual confidence was high in nine of the key findings, moderate in 10 key findings and low in one key finding. The main reason for downgrading review findings were concerns regarding the relevance and adequacy of the underlying data. As a result of the over-representation of HIV studies, our GRADE-CERQual assessment of some findings was downgraded in terms of relevance because the views described may not reflect those of people regarding vaccine trials for other pandemic or epidemic diseases. Adequacy relates to the degree of richness and quantity of data supporting a review finding. Moderate concerns about adequacy resulted in a downgrading of some review findings. Some factors were considered to be under the control of the trial team. These included how trial information was communicated and the inclusion of people in the community to help with trial information dissemination. Aspects of trial design were also considered under control of the trial team and included convenience of participation, provision of financial incentives and access to additional support services for those taking part in the trial. Other factors influencing people's decision to take part could be personal, from family, friends or wider society. From a personal perceptive, people had concerns about vaccine side effects, vaccine efficacy and possible impact on their daily lives (carer responsibilities, work, etc.). People were also influenced by their families, and the impact participation may have on relationships. The fear of stigma from society influenced the decision to take part. Also, from a societal perspective, the level of trust in governments' involvement in research and trial may influence a person's decision. Finally, the perceived rewards, both personal and societal, were influencing factors on the decision to participate. Personal rewards included access to a vaccine, improved health and improved disease knowledge, and a return to normality in the context of a pandemic or epidemic. Potential societal rewards included helping the community and contributing to science, often motivated by the memories of family and friends who had died from the disease. AUTHORS' CONCLUSIONS This review identifies many of the factors that influence a person's decision to take part in a vaccine trial, and these reflect findings from reviews that examine trials more broadly. However, we also recognise some factors that become more important in connection with a vaccine trial in the context of a pandemic or epidemic. These factors include the potential stigma of taking part, the possible adverse effects of a vaccine, the added motivation for helping society, the role of community leaders in trial dissemination, and the level of trust placed in governments and companies developing vaccines. These specific influences need to be considered by trial teams when designing, and communicating about, vaccine trials in the context of a pandemic or epidemic.

Abstract
Objective: The purpose of this study was to map and describe the studies that have investigated therapeutic alternatives for the management of paediatric multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19. Considering the origin of the studies performed (low-, middle- and high-income countries), a systematic scoping review was conducted with primary studies that reported the use of medications for the treatment of patients with MIS-C. Sources: The searches were performed in MEDLINE, Embase, Lilacs, Epistemonikos, CINAHL, and CENTRAL, in the grey literature (theses and dissertations from CAPES, ProQuest, and PROSPERO) and in clinical trial databases until May 2022. The selection and extraction of studies were performed independently by two reviewers. Summary of the findings: A total of 173 studies were included, most of which were published as case reports or series. No randomized controlled clinical trials (RCTs) were identified. The investigated drugs were immunoglobulins, glucocorticoids, monoclonal antibodies, anticoagulants, and antiplatelet agents. Conclusion: The dosages, when reported, were heterogeneous among the studies. The ethnicity and comorbidity of the participants were poorly reported. Monoclonal antibodies, drugs with higher costs, were mostly described in studies of high-income countries.

Abstract
Selective laser sintering (SLS) is an additive manufacturing process that has shown promise in the production of medical devices, including hip cups, knee trays, dental crowns, and hearing aids. SLS-based 3D-printed dosage forms have the potential to revolutionise the production of personalised drugs. The ability to manipulate the porosity of printed materials is a particularly exciting aspect of SLS. Porous tablet formulations produced by SLS can disintegrate orally within seconds, which is challenging to achieve with traditional methods. SLS also enables the creation of amorphous solid dispersions in a single step, rather than the multi-step process required with conventional methods. This review provides an overview of 3D printing, describes the operating mechanism and necessary materials for SLS, and highlights recent advances in SLS for biomedical and pharmaceutical applications. Furthermore, an in-depth comparison and contrast of various 3D printing technologies for their effectiveness in tissue engineering applications is also presented in this review.

Intravenous Magnesium: Prompt Use for Asthma in Children Treated in the Emergency Department (IMPACT-ED): Protocol for a Multicenter Pilot Randomized Controlled Trial. JMIR Res Protoc 2023; 12:e48302. [PMID: 37459153 PMCID: PMC10391520 DOI: 10.2196/48302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/26/2023] [Accepted: 05/29/2023] [Indexed: 08/03/2023] Open
Abstract
BACKGROUND Children managed for asthma in an emergency department (ED) may be less likely to be hospitalized if they receive intravenous magnesium sulfate (IVMg). Asthma guidelines recommend IVMg for severely sick children but note a lack of evidence to support this recommendation. All previous trials of IVMg in children with asthma have been too small to answer whether IVMg is effective and safe. A few major questions remain about IVMg. First, it has not been tested early in the course of ED treatment, when the impact on hospitalization would be greatest. Second, the clinical impact of hypotension, a known adverse effect of IVMg, has not been well characterized in previous research. Third, no trials have compared different IVMg doses or serial serum magnesium (total and ionized) concentrations to optimize dosing, so the most effective dose is unknown. A large, conclusive, randomized, placebo-controlled clinical trial of IVMg might be challenging due to the need to enroll and complete study procedures quickly, a lack of understanding of blood pressure changes after IVMg, and a lack of pharmacologic information to guide the optimal doses of IVMg to be tested. Therefore, a pilot study to inform the above gaps is warranted before conducting a definitive trial. OBJECTIVE The objectives of this study are to (1) demonstrate the feasibility of enrolling children with severe acute asthma in the ED in a multicenter, randomized controlled trial of a placebo, low-dose IVMg, or high-dose IVMg; (2) demonstrate the feasibility of timely delivery of study medication, assessment of blood pressure, and evaluation of adverse events in a standardized protocol; and (3) externally validate a previously constructed pharmacokinetic model and develop a combined pharmacokinetic/pharmacodynamic model for IVMg using magnesium (total and ionized) serum concentrations and their correlation with measures of efficacy and safety. METHODS This pilot trial tests procedures and gathers information to plan a definitive trial. The pilot trial will enroll as many as 90 children across 3 sites, randomize each child to 1 of 3 study arms, measure blood pressure frequently, and collect 3 blood samples from each participant with corresponding clinical asthma scores. RESULTS The project was funded by the National Heart, Lung, and Blood Institute (1 R34HL152047-2) in March 2022. Enrollment began in September 2022, and 43 children have been enrolled as of April 2023. We will submit the results for publication in late 2023. CONCLUSIONS The results of this study will guide the planning of a large, definitive, multicenter trial powered to evaluate if IVMg reduces hospitalization. Blood pressure measurements will inform a monitoring plan for the larger trial, and blood samples and asthma scores will be used to validate pharmacologic models to select the optimal dose of IVMg to be evaluated in the definitive trial.

Abstract
BACKGROUND Randomised controlled trials are often beset by problems with poor recruitment and retention. Information to support decisions on trial participation is usually provided as printed participant information sheets (PIS), which are often long, technical, and unappealing. Multimedia information (MMI), including animations and videos, may be a valuable alternative or complement to a PIS. The Trials Engagement in Children and Adolescents (TRECA) study compared MMI to PIS to investigate the effects on participant recruitment, retention, and quality of decision-making. METHODS We undertook six SWATs (Study Within A Trial) within a series of host trials recruiting children and young people. Potential participants in the host trials were randomly allocated to receive MMI-only, PIS-only, or combined MMI + PIS. We recorded the rates of recruitment and retention (varying between 6 and 26 weeks post-randomisation) in each host trial. Potential participants approached about each host trial were asked to complete a nine-item Decision-Making Questionnaire (DMQ) to indicate their evaluation of the information and their reasons for participation/non-participation. Odds ratios were calculated and combined in a meta-analysis. RESULTS Data from 3/6 SWATs for which it was possible were combined in a meta-analysis (n = 1758). Potential participants allocated to MMI-only were more likely to be recruited to the host trial than those allocated to PIS-only (OR 1.54; 95% CI 1.05, 2.28; p = 0.03). Those allocated to combined MMI + PIS compared to PIS-only were no more likely to be recruited to the host trial (OR = 0.89; 95% CI 0.53, 1.50; p = 0.67). Providing MMI rather than PIS did not impact on DMQ scores. Once children and young people had been recruited to host trials, their trial retention rates did not differ according to intervention allocation. CONCLUSIONS Providing MMI-only increased the trial recruitment rate compared to PIS-only but did not affect DMQ scores. Combined MMI + PIS instead of PIS had no effect on recruitment or retention. MMIs are a useful tool for trial recruitment in children and young people, and they could reduce trial recruitment periods.

Abstract
INTRODUCTION Medicine use in children with cystic fibrosis (CF) is complicated by inconsistent pharmacokinetics at variance with the general population, a lack of research into this and its effects on clinical outcomes. In the absence of established dose regimens, therapeutic drug monitoring (TDM) is a clinically relevant tool to optimize drug exposure and maximize therapeutic effect by the bedside. In clinical practice though, use of this is variable and limited by a lack of expert recommendations. AREAS COVERED We aimed to review the use of TDM in children with CF to summarize recent developments, current recommendations, and opportunities for future directions. We searched PubMed for relevant publications using the broad search terms "cystic fibrosis" in combination with the specific terms "therapeutic drug monitoring (TDM)" and "children." Further searches were undertaken using the name of identified drugs combined with the term "TDM." EXPERT OPINION Further research into the use of Bayesian forecasting and the relationship between exposure and response is required to personalize dosing, with the opportunity for the development of expert recommendations in children with CF. Use of noninvasive methods of TDM has the potential to improve accessibility to TDM in this cohort.

Abstract
BACKGROUND Pediatric research is crucial for the development of new scientific advancements, treatments, and therapies for adolescents. Yet relatively few pediatric clinical trials are conducted due to barriers to successful recruitment and retention, including knowledge and attitudes about clinical trials. Adolescents tend to experience greater autonomy to make decisions and have expressed interest in being part of the decision to participate in clinical trials. Increasing knowledge, positive attitudes, and self-efficacy related to clinical trials could positively impact the decision to participate in a pediatric clinical trial. However, there are currently few interactive, developmentally appropriate, web-based resources available to educate adolescents about clinical trials. DigiKnowItNews: Teen was created as a multimedia educational website to address the relatively low levels of enrollment in pediatric clinical trials and need for information to empower adolescents to make decisions about participating in clinical trials. METHODS This is a parallel group randomized controlled superiority trial to test the effectiveness of DigiKnowItNews: Teen, for improving factors related to clinical trial participation among adolescent and parents. Eligible parent-adolescent (ages 12 to 17 years) pairs will be randomly assigned to one of two conditions: intervention or wait-list control. All participants will complete pre- and post-test questionnaires and participants assigned to the intervention will receive access to review the DigiKnowItNews: Teen content for 1 week. Wait-list control participants will have the option to review DigiKnowItNews: Teen after study completion. The primary outcomes are knowledge about clinical research, attitudes, and beliefs toward pediatric clinical trials, self-efficacy for making decisions related to clinical trial participation, willingness to participate in a future clinical trial, procedural fears, and parent-adolescent communication quality. Overall feedback and satisfaction related to DigiKnowItNews: Teen will also be collected. DISCUSSION The trial will evaluate the effectiveness of DigiKnowIt News: Teen, an educational website about pediatric clinical trials for adolescents. If found effective in promoting factors related to future pediatric clinical trial participation, DigiKnowIt News: Teen could be used by adolescents, along with their parents, as they make the decision to participate in a clinical trial. Clinical trial researchers can also use DigiKnowIt News: Teen to aid their participant recruitment efforts. TRIAL REGISTRATION ClinicalTrials.gov NCT05714943. Registered on 02/03/2023.

Abstract
BACKGROUND The factors which influence participant retention in paediatric randomised controlled trials are under-researched. Retention may be more challenging due to child developmental stages, involving additional participants, and proxy-reporting of outcomes. This systematic review and meta-analysis explores the factors which may influence retention in paediatric trials. METHODS Using the MEDLINE database, paediatric randomised controlled trials published between 2015 and 2019 were identified from six general and specialist high-impact factor medical journals. The review outcome was participant retention for each reviewed trial's primary outcome. Context (e.g. population, disease) and design (e.g. length of trial) factors were extracted. Retention was examined for each context and design factor in turn, with evidence for an association being determined by a univariate random-effects meta-regression analysis. RESULTS Ninety-four trials were included, and the median total retention was 0.92 (inter-quartile range 0.83 to 0.98). Higher estimates of retention were seen for trials with five or more follow-up assessments before the primary outcome, those less than 6 months between randomisation and primary outcome, and those that used an inactive data collection method. Trials involving children aged 11 and over had the higher estimated retention compared with those involving younger children. Those trials which did not involve other participants also had higher retention, than those where they were involved. There was also evidence that a trial which used an active or placebo control treatment had higher estimated retention, than treatment-as-usual. Retention increased if at least one engagement method was used. Unlike reviews of trials including all ages of participants, we did not find any association between retention and the number of treatment groups, size of trial, or type of treatment. CONCLUSIONS Published paediatric RCTs rarely report the use of specific modifiable factors that improve retention. Including multiple, regular follow-ups with participants before the primary outcome may reduce attrition. Retention may be highest when the primary outcome is collected up to 6 months after a participant is recruited. Our findings suggest that qualitative research into improving retention when trials involve multiple participants such as young people, and their caregivers or teachers would be worthwhile. Those designing paediatric trials also need to consider the use of appropriate engagement methods. RESEARCH ON RESEARCH (ROR) REGISTRY: https://ror-hub.org/study/2561.

Abstract
BACKGROUND Unlicensed medicines are used across the UK to treat an individual's clinical needs when there are no appropriate licensed alternatives. Patients, carers and parents have reported facing challenges with unlicensed medicines at the points of transfer of care between settings, a key time when medication errors may occur. There is little known about the patient journey as a whole, or the factors affecting patient care when receiving an unlicensed medicine. OBJECTIVE A systematic review of UK literature to better understand factors that affect the entire patient journey from the decision to initiate treatment with an unlicensed medicine to the point at which treatment is supplied through a community pharmacy or ends. METHODS Scopus, OVID EMCARE, EMBASE, OVID Medline ALL, CINAHL, Web of Science and Joanna Briggs Institute were searched from 1968 (introduction of the Medicines Act) until November 2020, using the PRISMA guidelines. Narrative synthesis of UK studies was employed to analyse descriptive and qualitative data on any reported findings that would impact the patient journey or care related to the use of unlicensed medicines, and any described barriers or enablers. RESULTS Forty-five studies met criteria for final inclusion, with high levels of heterogeneity in terms of designs and methods. Specific challenges that were seen to impact the continuity of care across care settings, patient safety and provision of patient-centred care included diversity of clinical needs and impact of patient population age; healthcare professional awareness and acceptability of the use of unlicensed medicines; the hierarchical structure of the NHS; inconsistent doses and formulations with varying bioequivalence; patient/parent/carer/public awareness of unlicensed medicines use and perceived acceptability. CONCLUSIONS This review identified a clear need for consistent information to be provided to healthcare professional and patients alike to support the safe and effective use of unlicensed medicines across care settings.

Abstract
BACKGROUND AND OBJECTIVE Contradictory pharmacokinetic (PK) results have been observed between obese adults and obese adolescents, with absolute clearance (CL) reported to be either unaltered, lower, or higher in obese adolescents compared to obese adults. This study investigates the PK of vancomycin in adolescents and adults who are overweight or obese. METHODS Data from 125 overweight and obese adolescents (aged 10-18 years, weight 28.3-188 kg) and 81 overweight and obese adults (aged 29-88 years, weight 66.7-143 kg) were analysed using population PK modelling. In addition to age, sex, renal function estimates, and regular weight descriptors, we evaluated standard weight (WTstandard, defined as weight for length, age, and sex in adolescents and weight for length in adults) and excess weight (WTexcess, defined as total body weight (TBW) minus WTstandard) as covariates in order to distinguish between weight resulting from length versus weight resulting from obesity. RESULTS Analyzing adolescents and adults together, vancomycin CL was found to increase with TBW and decrease with increasing age (p < 0.001). A covariate analysis investigating adolescents and adults separately found that vancomycin CL increased with WTstandard in adolescents and adults, albeit with different functions, with adolescents having a higher CL per WTstandard than adults. Moreover, in this separate model, adolescent males had 21% higher CL than adolescent females of the same WTstandard, while in adults, CL decreased with increasing age (p < 0.001). CONCLUSION There are apparent differences in vancomycin CL in overweight and obese adults versus overweight and obese adolescents, implying that dosing of vancomycin cannot be directly extrapolated between these populations.

Abstract
INTRODUCTION The unique evidentiary, economic and ethical challenges associated with health technology assessment (HTA) of precision therapies limit access to novel drugs and therapeutics for children and youth, for whom such challenges are amplified. We elicited citizens' perspectives about values-based criteria relevant to the assessment of paediatric precision therapies to inform the development of a child-tailored HTA framework. METHODS We held four citizen panels virtually in May-June 2021, informed by a plain-language citizen brief summarizing global and local evidence about the challenges, policy and programmatic options and implementation strategies related to enhancing access to precision therapies for Canadian children and youth. Panellists were recruited through a nationally representative database, medical/patient networks and social media. We inductively coded and thematically analysed panel transcripts to generate themes and identify priority values. RESULTS The perspectives of panellists (n = 45) coalesced into four overlapping themes, with attendant subthemes, relevant to a child-tailored HTA framework: (1) Childhood Distinctions: vulnerability, 'fair innings', future potential, family impacts; (2) Voice: agency of children and youth; lived versus no lived experience; (3) One versus Many: disease severity, rarity, equity, unmet need and (4) Health System Governance: funding, implementation inequities, effectiveness and safety. Participants broadly agreed that childhood distinctions, particularly family impacts, justify child-tailored HTA. Dissent arose over whose voice should inform HTA and how such perspectives are best incorporated. CONCLUSIONS Citizens can offer unique insights into criteria relevant to the development or revision of HTA frameworks to capture holistic, societally responsive dimensions of value attached to unique contexts or populations, including children. Balancing the hopes and expectations of patients and caregivers for access to expensive but potential life-altering therapies against the opportunity costs borne by encompassing health systems is a fundamental challenge that will require rigorous methods to elicit, weigh and reconcile varied views. PATIENT OR PUBLIC CONTRIBUTION A patient advocate served on the steering committee of this study and co-authored this article. Key informants for the Citizen Brief included patient advocates and caregivers; a separate patient advocate reviewed the Brief before dissemination. Qualitative and quantitative data were collected from the general public and caregivers of children, with written consent.
