RESUMO
Appearance-related comparisons (A-RCs) in body dysmorphic disorder (BDD) are under researched despite their probable role in disorder maintenance. The present study therefore aimed to explore the nature (frequency, direction and automaticity), and functions of A-RCs in BDD. N = 43 including people with BDD (n = 23) and controls (n = 20) matched approximately on age and sex were recruited. A mixture of standardized and devised questionnaires on body image and A-RCs were completed. A-RCs were significantly more frequent, generally more upward (to more attractive standards of comparison), and more automatic in people with BDD relative to the control group. People with BDD also held significantly stronger agreement with beliefs about A-RCs as serving functions of: self-evaluation, self-improvement, self-enhancement, and in particular, self-loathing (a way to confirm beliefs about physical unattractiveness) and social threat management. This research presents evidence that the nature and functions of A-RCs in BDD have a role in this disorder's maintenance. Clinical implications, limitations, and future directions for research are discussed.
RESUMO
OBJECTIVE: Severe early-onset fetal growth restriction (FGR) causes stillbirth, neonatal death and neurodevelopmental impairment. Poor maternal spiral artery remodelling maintains vasoactive responsiveness but is susceptible to treatment with sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor, which may improve perinatal outcomes. DESIGN: Superiority, double-blind randomised controlled trial. SETTING: A total of 20 UK fetal medicine units. POPULATION: Pregnancies affected by FGR, defined as an abdominal circumference below the tenth centile with absent end-diastolic flow in the umbilical artery between 22+0 and 29+6 weeks of gestation. METHODS: Treatment with sildenafil (25 mg three times/day) or placebo until delivery or 32 weeks of gestation. MAIN OUTCOME MEASURES: All infants alive at hospital discharge were assessed for cardiovascular function and cognitive, speech/language and neuromotor impairment at 2 years of age. The primary outcome was survival without cerebral palsy or neurosensory impairment, or a Bayley-III composite score of >85. RESULTS: In total, 135 women were randomised between November 2014 and July 2016 (70 to sildenafil and 65 to placebo). We previously published that there was no improvement in time to delivery or perinatal outcomes with sildenafil. In all, 75 babies (55.5%) were discharged alive, with 61 infants eligible for follow-up (32 sildenafil and 29 placebo). One infant died (placebo), three mothers declined and ten mothers were uncontactable. There was no difference in neurodevelopment or blood pressure following treatment with sildenafil. Infants who received sildenafil had a larger head circumference at 2 years of age (median difference 49.2 cm, IQR 46.4-50.3, vs 47.2 cm, 95% CI 44.7-48.9 cm). CONCLUSIONS: Sildenafil therapy did not prolong pregnancy or improve perinatal outcomes and did not improve infant neurodevelopment in FGR survivors. Therefore, sildenafil should not be prescribed for this condition.
RESUMO
BACKGROUND: Despite global efforts to improve paediatric clinical trials, significant delays continue in paediatric drug approvals. Collaboration between research networks is needed to address these delays. This paper is a first step to promote interoperability between paediatric networks from different jurisdictions by comparing drivers for, and content of, metrics about clinical trial conduct. METHODS: Three paediatric networks, Institute for Advanced Clinical Trials for Children, the Maternal Infant Child and Youth Research Network and conect4children, have each developed metrics to address delays and create efficiencies. We identified the methodology by which each network identified metrics, described the metrics of each network, and mapped consistency to come to consensus about core metrics that networks could share. RESULTS: Metric selection was driven by site quality improvement in one network (11 metrics), by network performance in one network (13 metrics), and by both in one network (five metrics). The domains of metrics were research capacity/capability, site identification/feasibility, trial start-up, and recruitment/enrolment. The network driven by site quality improvement did not have indicators for capacity/capability or identification/feasibility. Fifteen metrics for trial start up and conduct were identified. Metrics related to site approvals were found in all three networks. The themes for metrics can inform the development of 'shared' metrics. CONCLUSION: We found disparity in drivers, methodology and metrics. Tackling this disparity will result in a unified approach to addressing delays in paediatric drug approvals. Collaborative work to define inter-operable metrics globally is outlined.

Objective: To describe perinatal and maternal outcomes of preterm prelabour rupture of membranes (PPROM) before 23 weeks' gestation in a national cohort. Design: Prospective observational study. Setting: National population based cohort study with the UK Obstetric Surveillance System (UKOSS), a research infrastructure of all 194 obstetric units in the UK, 1 September 2019 to 28 February 2021. Participants: 326 women with singleton and 38 with multiple pregnancies with PPROM between 16+0 and 22+6 weeks+days' gestation. Main outcome measures: Perinatal outcomes of live birth, survival to discharge from hospital, and severe morbidity, defined as intraventricular haemorrhage grade 3 or 4, or requiring supplemental oxygen at 36 weeks' postmenstrual age, or both. Maternal outcomes were surgery for removal of the placenta, sepsis, admission to an intensive treatment unit, and death. Clinical data included rates of termination of pregnancy for medical reasons. Results: Perinatal outcomes were calculated with all terminations of pregnancy for medical reasons excluded, and a worst-best range was calculated assuming that all terminations for medical reasons and those with missing data would have died (minimum value) or all would be liveborn (maximum value). For singleton pregnancies, the live birth rate was 44% (98/223), range 30-62% (98/326-201/326), perinatal survival to discharge from hospital was 26% (54/207), range 17-53% (54/326-173/326), and 18% (38/207), range 12-48% (38/326-157/326) of babies survived without severe morbidity. The rate of maternal sepsis was 12% (39/326) in singleton and 29% (11/38) in multiple pregnancies (P=0.004). Surgery for removal of the placenta was needed in 20% (65/326) and 16% (6/38) of singleton and twin pregnancies, respectively. Five women became severely unwell with sepsis; two died and another three required care in the intensive treatment unit. Conclusions: In this study, 26% of women who had very early PPROM with expectant management had babies that survived to discharge from hospital. Morbidity and mortality rates were high for both mothers and neonates. Maternal sepsis is a considerable risk that needs more research. These data should be used in counselling families with PPROM before 23 weeks' gestation, and currently available guidelines should be updated accordingly.
RESUMO
Introduction: To ensure the quality of clinical trial safety data, universal data standards are required. In 2019 the International Neonatal Consortium (INC) published a neonatal adverse event severity scale (NAESS) to standardize the reporting of adverse event (AE) severity. In this study the reliability of AE severity grading with INC NAESS was prospectively assessed in a real-world setting. Methods: Severity of AEs was assessed by two independent observers at each of four centers across the world. In each center two series of 30 neonatal adverse events were assessed by both observers: in a first phase with a generic (Common Terminology Criteria for Adverse Events, CTCAE) severity scale not specific to neonates, and in a second phase with INC NAESS (after a structured training). Intraclass correlation coefficients (ICC) were calculated to express inter-rater agreement in both phases, and bootstrap sampling was used to compare them. Results: 120 AEs were included in each of both phases. The ICC with the use of INC NAESS in phase 2 was 0.69. This represents a significant but modest improvement in comparison to the initial ICC of 0.66 in phase 1 (confidence interval of ratio of ICC in phase 2 to phase 1 = 1.005-1.146; excludes 1). The ICC was higher for those AEs for which a diagnosis specific AE severity table was available in INC NAESS (ICC 0.80). Discussion: Good inter-rater reliability of the INC NAESS was demonstrated in four neonatal intensive care units (NICUs) across the globe. The ICC is comparable to what is reported for scales with similar purposes in different populations. There is a modest, but significant, improvement in inter-rater agreement in comparison to the naïve phase without INC NAESS. The better performance when reviewers use AE-specific NAESS tables highlights the need to expand the number of AEs that are covered by specific criteria in the current version of INC NAESS.
RESUMO
BACKGROUND: Pharmacokinetic (PK) data underlying paediatric penicillin dosing remain limited, especially in critical care. OBJECTIVES: The primary objective of the Neonatal and Paediatric Pharmacokinetics of Antimicrobials study (NAPPA) was to characterize PK profiles of commonly used penicillins using data obtained during routine care, to further understanding of PK variability and inform future evidence-based dosing. METHODS: NAPPA was a multicentre study of amoxicillin, co-amoxiclav, benzylpenicillin, flucloxacillin and piperacillin/tazobactam. Patients were recruited with informed consent. Antibiotic dosing followed standard of care. PK samples were obtained opportunistically or at optimal times, frozen and analysed using UPLC with tandem MS. Pharmacometric analysis was undertaken using NONMEM software (v7.3). Model-based simulations (nâ=â10â000) tested PTA with British National Formulary for Children (BNFC) and WHO dosing. The study had ethical approval. RESULTS: For the combined IV PK model, 963 PK samples from 370 participants were analysed simultaneously incorporating amoxicillin, benzylpenicillin, flucloxacillin and piperacillin data. BNFC high-dose regimen simulations gave these PTA results (median fT>MIC at breakpoints of specified pathogens): amoxicillin 100% (Streptococcus pneumoniae); benzylpenicillin 100% (Group B Streptococcus); flucloxacillin 48% (MSSA); and piperacillin 100% (Pseudomonas aeruginosa). Oral population PK models for flucloxacillin and amoxicillin enabled estimation of first-order absorption rate constants (1.16 h-1 and 1.3 h-1) and bioavailability terms (62.7% and 58.7%, respectively). CONCLUSIONS: NAPPA represents, to our knowledge, the largest prospective combined paediatric penicillin PK study undertaken to date, and the first paediatric flucloxacillin oral PK model. The PTA results provide evidence supportive of BNFC high-dose IV regimens for amoxicillin, benzylpenicillin and piperacillin.

Several high-risk medical devices for children have become unavailable in the European Union (EU), since requirements and costs for device certification increased markedly due to the EU Medical Device Regulation. The EU-funded CORE-MD project held a workshop in January 2023 with experts from various child health specialties, representatives of European paediatric associations, a regulatory authority and the European Commission Directorate General Health and Food Safety. A virtual follow-up meeting took place in March 2023. We developed recommendations for investigation of high-risk medical devices for children building on participants' expertise and results of a scoping review of clinical trials on high-risk medical devices in children. Approaches for evaluating and certifying high-risk medical devices for market introduction are proposed.
RESUMO
Pediatric physiologically based pharmacokinetics modeling in drug development has grown in the past decade but uncertainty remains regarding ontogeny of some drug metabolizing enzymes. In this study, a midazolam and 1-hydroxymidazolam physiologically based pharmacokinetic model (PBPK) model was developed and used to define the ontogeny for hepatic cytochrome P450 (CYP) 3A4 and uridine diphosphate glucuronosyl transferase (UGT) 2B4. Data for model development and pharmacokinetic studies on intravenous midazolam in adults and pediatrics were collated from the literature. The PBPK model was verified in the adult population and then used to compare the performance of two ontogeny profiles for CYP3A4 in terms of parent drug elimination in pediatrics. Four studies also published data on the 1-hydroxymidazolam, and this was used to evaluate the known ontogeny for UGT2B4.For midazolam elimination, the Upreti CYP3A4 ontogeny performed better than Salem; mean error (bias) and mean squared error (precision) were 0.14 and 0.064 compared with 0.69 and 1.21, respectively. For 1-hydroxymidazolam elimination, the Simcyp default ontogeny of UGT2B4 appeared to perform best for studies covering the age range 0.5 to 15.7 years, while for a study in younger ages 0 to 1 years it was the Badee UGT2B4 ontogeny. In preterm neonates, overall expression of UGT appeared to be around 10% of that in adults.Identifying the optimal model of CYP3A4 ontogeny is important for the regulatory use of PBPK. The results for midazolam are conclusive but research about other CYP3A4 metabolized compounds will underpin generalizability of the CYP3A4 ontogeny. UGT2B4 ontogeny is less certain, but this study indicates the most likely scenarios. SIGNIFICANCE STATEMENT: A PBPK model for midazolam and 1-hydroxymidazolam was developed to test various ontogeny scenarios for CYP3A4 and UGT2B4. The CYP3A4 ontogeny of Upreti resulted in more accurate prediction of midazolam CL across nine clinical studies, age range birth to 18 years. 1-Hydroxy midazolam was used as a marker of UGT. The Simcyp default 'no ontogeny' profiles for UGT2B4 performed the best; however, for <1 year of age, there was some evidence of overactivity of this enzyme compared to adults.

Setting-up a high quality, compliant and efficient pharmacovigilance (PV) system in multi-country clinical trials can be more challenging for academic sponsors than for companies. To ensure the safety of all participants in academic studies and that the PV system fulfils all regulations, we set up a centralized PV system that allows sponsors to delegate work on PV. This initiative was put in practice by our Inserm-ANRS MIE PV department in two distinct multinational European consortia with 19 participating countries: conect4children (c4c) for paediatrics research and EU-Response for Covid-19 platform trials. The centralized PV system consists of some key procedures to harmonize the complex safety processes, creation of a local safety officer (LSO) network and centralization of all safety activities. The key procedures described the safety management plan for each trial and how tasks were shared and delegated between all stakeholders. Processing of serious adverse events (SAEs) in a unique database guaranteed the full control of the safety data and continuous evaluation of the risk-benefit ratio. The LSO network participated in efficient regulatory compliance across multiple countries. In total, there were 1312 SAEs in EU-Response and 83 SAEs in c4c in the four trials. We present here the lessons learnt from our experience in four clinical trials. We managed heterogeneous European local requirements and implemented efficient communication with all trial teams. Our approach builds capacity for PV that can be used by multiple academic sponsors.

Many medicines are used "off-label" in children outside the terms of the license. Feasible pediatric clinical trials are a challenge to design. Conect4children (c4c) is an Innovative Medicines Initiative project to set up a pan-European pediatric clinical trial network aiming to facilitate the development of new medicines for children. To optimize pediatric trial development by promoting innovative trial design, c4c set up a European multidisciplinary advice service, including the voice of young patients and families, tailored to industry and academia. A network of experts was established to provide multidisciplinary advice to trial sponsors. Experts were selected to join clinical and innovative methodology expert groups. A patient and public involvement (PPI) database, to include the expert opinion of patients and parents/carers was formed. A stepwise process was developed: (1) sponsors contact c4c, (2) scoping interview takes place, (3) ad hoc advice group formed, (5) advice meeting held, and (6) advice report provided. Feedback on the process was collected. Twenty-four clinical and innovative methodology expert groups (>400 experts) and a PPI database of 135 registrants were established. As of September 30, 2022, 36 advice requests were received, with 25 requests completed. Clinical and methodology experts and PPI representatives participated in several advice requests. Sponsors appreciated the advice quality and the multidisciplinary experts from different countries, including experts not known before. Experts and PPI participants were generally satisfied with the process. The c4c project has shown successful proof of concept for a service that presents a new framework to plan innovative and feasible pediatric trials.

BACKGROUND: Recombinant human (rh)IGF-1/IGFBP-3 protein complex, administered as a continuous intravenous infusion in preterm infants, is being studied for the prevention of complications of prematurity. METHODS: We conducted in vitro studies to evaluate the physical and chemical compatibility of rhIGF-1/IGFBP-3 with medications routinely administered to preterm neonates. In vitro mixing of rhIGF-1/IGFBP-3 drug product with small-molecule test medications plus corresponding controls was performed. Physical compatibility was defined as no color change, precipitation, turbidity, gas evolution, no clinically relevant change in pH/osmolality or loss in medication content. Chemical compatibility of small molecules was assessed using liquid chromatography (e.g., reverse-phase HPLC and ion chromatography), with incompatibility defined as loss of concentration of ≥ 10%. A risk evaluation was conducted for each medication based on in vitro compatibility data and potential for chemical modification. RESULTS: In vitro physical compatibility was established for 11/19 medications: caffeine citrate, fentanyl, fluconazole, gentamicin, insulin, intravenous fat emulsion, midazolam, morphine sulfate, custom-mixed parenteral nutrition solution (with/without electrolytes), parenteral nutrition solution + intravenous fat emulsion, and vancomycin (dosed from a 5 mg/mL solution), but not for 8/19 medications: amikacin, ampicillin, dopamine, dobutamine, furosemide, meropenem, norepinephrine, and penicillin G, largely owing to changes in pH after mixing. Small-molecule compatibility was unaffected post-mixing, with no loss of small-molecule content. For physically compatible medications, risk analyses confirmed low probability and severity of a risk event. CONCLUSION: Co-administration of rhIGF-1/rhIGFBP-3 drug product with various medications was assessed by in vitro studies using case-by-case risk analyses to determine the suitability of the products for co-administration.

BACKGROUND: There are no generally accepted age-appropriate reference ranges for laboratory values in neonates. This also matters for drug development. The International Neonatal Consortium (INC) is engaged to define actionable reference ranges of commonly used laboratory values in neonates. METHODS: A structured literature search was performed to identify standards or recommendations for publications that present neonatal laboratory data to assess the publication quality of laboratory values in neonates. Using a modified Delphi approach, an assessment and data extraction instrument to screen on completeness of information was developed. RESULTS: On 2908 hits, 281 papers were retained for full reading and 257 for data extraction. None of the papers reported a publication standard. Using the extraction instrument, most papers presented single country or unit findings. The median number of neonates was 120, with uncertainty on single or repeated measurements. Clinically meaningful information on age, sex, and medical conditions was commonly provided. Information on pharmacotherapy, equipment, analytical method, or laboratory location was rarely mentioned. CONCLUSIONS: Published information on laboratory values for neonates is sparse, not systematic, and incomplete. This undermines efforts to compare treatments, safety monitoring, or clinical management. Furthermore, there appears to be no standard yet to report laboratory values in neonates. IMPACT: There are no generally accepted age-appropriate reference ranges for laboratory values in neonates, leading to a significant knowledge gap, also for safety reporting and drug development in neonates. We performed a literature search to identify standards or recommendations for publications on neonatal laboratory data and to assess the publication quality of laboratory values in clinical studies involving neonates. Standards or recommendations for publications that present neonatal laboratory data were not identified, while published information on laboratory values for neonates is sparse, not systematic, and incomplete.

INTRODUCTION: Neonatal sepsis is a leading cause of infant mortality worldwide with non-specific and varied presentation. We aimed to catalogue the current definitions of neonatal sepsis in published randomised controlled trials (RCTs). METHOD: A systematic search of the Embase and Cochrane databases was performed for RCTs which explicitly stated a definition for neonatal sepsis. Definitions were sub-divided into five primary criteria for infection (culture, laboratory findings, clinical signs, radiological evidence and risk factors) and stratified by qualifiers (early/late-onset and likelihood of sepsis). RESULTS: Of 668 papers screened, 80 RCTs were included and 128 individual definitions identified. The single most common definition was neonatal sepsis defined by blood culture alone (n = 35), followed by culture and clinical signs (n = 29), and then laboratory tests/clinical signs (n = 25). Blood culture featured in 83 definitions, laboratory testing featured in 48 definitions while clinical signs and radiology featured in 80 and 8 definitions, respectively. DISCUSSION: A diverse range of definitions of neonatal sepsis are used and based on microbiological culture, laboratory tests and clinical signs in contrast to adult and paediatric sepsis which use organ dysfunction. An international consensus-based definition of neonatal sepsis could allow meta-analysis and translate results to improve outcomes.

To support informed decisions on drug registration and prescription, clinical trials need tools to assess the efficacy and safety signals related to a given therapeutic intervention. Standardized assessment facilitates reproducibility of results. Furthermore, it enables weighted comparison between different interventions, instrumental to facilitate shared decisions. When focused on adverse events in clinical trials, tools are needed to assess seriousness, causality and severity. As part of such a toolbox, the international Neonatal Consortium (INC) developed a first version of the neonatal adverse event severity scale (NAESS). This version underwent subsequent validation in retro-and prospective trials to assess its applicability and impact on the inter-observer variability. Regulators, sponsors and academic researchers also reported on the use of the NAESS in regulatory documents, trial protocols and study reports. In this paper, we aim to report on the trajectory, current status and impact of the NAESS score, on how stakeholders within INC assess its relevance, and on perspectives to further develop this tool.
RESUMO
BACKGROUND: Medicines designed for adults may be inappropriate for use in children in terms of strength, dosage form and/or excipient content. There is currently no standardised method of assessing the age-appropriateness of a medicine for paediatric use. AIM: To develop and test a tool to assess whether a dosage form (formulation) is appropriate for children and estimate the proportion of formulations considered 'inappropriate' in a cohort of hospitalised paediatric patients with a chronic illness. METHOD: A multi-phase study: patient data collection, tool development, case assessments and tool validation. Inpatients aged 0-17 years at two UK paediatric/neonatal hospitals during data collection periods between January 2015 and March 2016. Written informed consent/assent was obtained. Medicines assessed were new or regularly prescribed to inpatients as part of their routine clinical care. All medicine administration episodes recorded were assessed using the Age-appropriate Formulation tool. The tool was developed by a consensus approach, as a one-page flowchart. Independent case assessments were evaluated in 2019. RESULTS: In 427 eligible children; 2,199 medicine administration episodes were recorded. Two assessors reviewed 220 episodes in parallel: percentage exact agreement was found to be 91.7% (99/108) and 93.1% (95/102). In total, 259/2,199 (11.8%) medicine administration episodes involved a dosage form categorised as 'age-inappropriate'. CONCLUSION: A novel tool has been developed and internally validated. The tool can identify which medicines would benefit from development of an improved paediatric formulation. It has shown high inter-rater reliability between users. External validation is needed to further assess the tool's utility in different settings.

The concept of health equity-the attainment of the highest possible level of health for all members of society-requires equitable access to all aspects of healthcare, including pediatric drug development. However, many communities are under-represented in pediatric drug development programs. Barriers to participation include geographic, economic, racial/ethnic bias, legal, cultural, linguistic, and other factors. While there is no "one size fits all" approach to addressing these barriers, community engagement and collaboration is recognized by the Centers for Disease Control, the World Health Organization, and other global health organizations as a cornerstone for building a more equitable healthcare system. In this article, we will present case studies of stakeholder and community engagement in clinical research for rare diseases and other areas of healthcare, as examples of strategies and practices for actively involving under-represented communities and fostering their participation in pediatric drug development programs. These studies may serve as templates for facilitating equity in pediatric drug development from aspiration into operation.

Developing suitable paediatric formulations and ensuring access to them by the greatest number of the 2.2 billion children worldwide are equally important to provide optimal pharmacotherapy. This review focuses on the progress made over the last two decades with paediatric oral formulations with respect to evidence for acceptability and dosing flexibility of liquid and solid oral dosage forms. It also discusses the clinical needs for, and the access to, paediatric formulations for existing authorised medicines. A significant body of new knowledge now supports the acceptability of solid oral dosage forms in children, resulting in an increasing number of medicines commercialised as multiparticulates, including minitablets that are starting to be brought to market. However, there are gaps with these formulations that deserve more research. Even though efforts have been made to identify medicines in need of age-appropriate formulations, there is no common priority list shared internationally. Such prioritisation would help to develop paediatric formulations with the greatest potential for providing a health benefit to children worldwide. In addition, available data highlight that paediatric formulation access is fragmented and unequal, with commercialisation of suitable paediatric formulations too often limited to some countries/regions. We propose actions to better align decisions during the development of paediatric formulations and promote a more globalised approach to facilitate registration pathways between different jurisdictions. Furthermore, discussions about alignment between approval, pricing and reimbursement processes should also happen, leaving working in siloes behind us. It is time for adults to start thinking outside the box for children.
