Patient and parent perspectives on paediatric cancer multidisciplinary team working and national advisory panels in the UK: a qualitative research study. Arch Dis Child 2024; 109:321-325. [PMID: 38290777 DOI: 10.1136/archdischild-2023-326604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 01/08/2024] [Indexed: 02/01/2024]
Abstract
OBJECTIVE The concept of patient-centred care is central to the role of cancer multidisciplinary teams (MDTs) and particularly pertinent with the recent rise in number of virtual national advisory panels (NAPs) for childhood cancer in the UK. We sought to explore patient and caregiver views regarding MDT working and NAPs. METHODS Three focus groups were undertaken between March 2019 and January 2020. RESULTS Sixteen participants attended. All regarded MDTs and NAPs highly, while highlighting patient involvement in decision-making should not be diluted by this process. The importance of personalised consultations was stressed, acknowledging that information-sharing preferences may change with circumstance and time. Most participants felt they had not been actively involved in decisions, including those made following MDT or NAP discussions. Group suggestions to improve patient-centred care included a clinician knowing them presenting their case, referral proformas to include family-related factors and an advocate attending meetings to represent the patient/family view. CONCLUSION Several changes have been driven forward by this work, including the modification of NAP referral proformas to include additional information. Patient and parent perspectives are now embedded into a best practice model for the NAPs to promote personalised recommendations at national level.

The use of routinely collected electronic prescribing data to benchmark intravenous antibiotic use between two tertiary paediatric haematology-oncology inpatient units: a retrospective study. JAC Antimicrob Resist 2024; 6:dlad142. [PMID: 38161969 PMCID: PMC10753649 DOI: 10.1093/jacamr/dlad142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 12/05/2023] [Indexed: 01/03/2024] Open
Abstract
Background High-quality systematic data on antimicrobial use in UK inpatient paediatric haematology-oncology services are lacking, despite this population being at high risk from antimicrobial exposure and resistance. Objectives We conducted a retrospective study to demonstrate how routinely collected electronic prescribing data can address this issue. Patients and methods This retrospective study describes and compares IV antibiotic consumption between two UK paediatric haematology-oncology inpatient units, between 2018 and 2022. Both sites provide similar services and receive proactive antimicrobial stewardship input. Data were extracted from each site's antimicrobial surveillance system, which report monthly days of therapy (DOT) per 100 patient-days (PD). Consumption was reported for specific and total antibiotics. Trends were modelled using linear regression and autoregressive moving average models. Results Total IV antibiotic consumption at each site was similar. Median monthly DOT per 100 PD were 25.9 (IQR: 22.1-34.0) and 29.4 (24.2-34.9). Total antibiotic use declined at both sites, with estimated annual yearly reductions of 3.52 DOT per 100 PD (95% CI: 0.46-6.59) and 2.57 (1.30-3.85). Absolute consumption was similar for carbapenems, piperacillin/tazobactam and aminoglycosides, whilst ceftriaxone and teicoplanin demonstrated approximately 3-fold relative differences in median monthly consumption. Meropenem, piperacillin/tazobactam, teicoplanin, vancomycin and gentamicin all demonstrated statistically significant reductions in use over time at either one or both sites, although this was most marked for piperacillin/tazobactam and vancomycin. Conclusions Routinely collected electronic prescribing data can aid benchmarking of antibiotic use in paediatric haematology-oncology inpatients, highlighting areas to target stewardship strategies, and evaluating their impact. This approach should be rolled out nationally, and to other high-risk groups.

Bevacizumab, Irinotecan, or Topotecan Added to Temozolomide for Children With Relapsed and Refractory Neuroblastoma: Results of the ITCC-SIOPEN BEACON-Neuroblastoma Trial. J Clin Oncol 2024:JCO2300458. [PMID: 38190578 DOI: 10.1200/jco.23.00458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 07/25/2023] [Accepted: 10/05/2023] [Indexed: 01/10/2024] Open
Abstract
PURPOSE Outcomes for children with relapsed and refractory high-risk neuroblastoma (RR-HRNB) remain dismal. The BEACON Neuroblastoma trial (EudraCT 2012-000072-42) evaluated three backbone chemotherapy regimens and the addition of the antiangiogenic agent bevacizumab (B). MATERIALS AND METHODS Patients age 1-21 years with RR-HRNB with adequate organ function and performance status were randomly assigned in a 3 × 2 factorial design to temozolomide (T), irinotecan-temozolomide (IT), or topotecan-temozolomide (TTo) with or without B. The primary end point was best overall response (complete or partial) rate (ORR) during the first six courses, by RECIST or International Neuroblastoma Response Criteria for patients with measurable or evaluable disease, respectively. Safety, progression-free survival (PFS), and overall survival (OS) time were secondary end points. RESULTS One hundred sixty patients with RR-HRNB were included. For B random assignment (n = 160), the ORR was 26% (95% CI, 17 to 37) with B and 18% (95% CI, 10 to 28) without B (risk ratio [RR], 1.52 [95% CI, 0.83 to 2.77]; P = .17). Adjusted hazard ratio for PFS and OS were 0.89 (95% CI, 0.63 to 1.27) and 1.01 (95% CI, 0.70 to 1.45), respectively. For irinotecan ([I]; n = 121) and topotecan (n = 60) random assignments, RRs for ORR were 0.94 and 1.22, respectively. A potential interaction between I and B was identified. For patients in the bevacizumab-irinotecan-temozolomide (BIT) arm, the ORR was 23% (95% CI, 10 to 42), and the 1-year PFS estimate was 0.67 (95% CI, 0.47 to 0.80). CONCLUSION The addition of B met protocol-defined success criteria for ORR and appeared to improve PFS. Within this phase II trial, BIT showed signals of antitumor activity with acceptable tolerability. Future trials will confirm these results in the chemoimmunotherapy era.

Presence and identity of Babesia microti in Ireland. Ticks Tick Borne Dis 2023; 14:102221.

Abstract
Babesia microti is a tick-transmitted protozoan parasite of wildlife that can also cause serious disease in humans. It is now well established that B. microti represents an assemblage of different strains or species, only some of which are important zoonotic pathogens. Therefore, in order to assess the potential public health risk associated with B. microti in any given location, it is important to determine the strains that are present. This is the first study on the presence and identity of B. microti in Ireland. Overall, 314 wood mice (Apodemus sylvaticus), 243 bank voles (Myodes glareolus) and 634 questing Ixodes ricinus nymphs collected in various locations across Ireland were screened for the presence of B. microti by metabarcoding and nested PCR, respectively. Overall 8 rodent spleen samples (1.4%) were positive for B. microti, while all tick samples tested negative. Rodent isolates were identified as the 'Munich' strain which rarely causes human disease and is chiefly transmitted by the mouse tick, Ixodes trianguliceps. Together with reports from the UK these results suggest that B. microti does not represent a significant public health risk in Britain or Ireland.

Polygenic contributions to performance on the Balloon Analogue Risk Task. Mol Psychiatry 2023; 28:3524-3530. [PMID: 37582857 PMCID: PMC10618088 DOI: 10.1038/s41380-023-02123-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 05/03/2023] [Accepted: 06/07/2023] [Indexed: 08/17/2023]
Abstract
Risky decision-making is a common, heritable endophenotype seen across many psychiatric disorders. Its underlying genetic architecture is incompletely explored. We examined behavior in the Balloon Analogue Risk Task (BART), which tests risky decision-making, in two independent samples of European ancestry. One sample (n = 1138) comprised healthy participants and some psychiatric patients (53 schizophrenia, 42 bipolar disorder, 47 ADHD); the other (n = 911) excluded for recent treatment of various psychiatric disorders but not ADHD. Participants provided DNA and performed the BART, indexed by mean adjusted pumps. We constructed a polygenic risk score (PRS) for discovery in each dataset and tested it in the other as replication. Subsequently, a genome-wide MEGA-analysis, combining both samples, tested genetic correlation with risk-taking self-report in the UK Biobank sample and psychiatric phenotypes characterized by risk-taking (ADHD, Bipolar Disorder, Alcohol Use Disorder, prior cannabis use) in the Psychiatric Genomics Consortium. The PRS for BART performance in one dataset predicted task performance in the replication sample (r = 0.13, p = 0.000012, pFDR = 0.000052), as did the reciprocal analysis (r = 0.09, p = 0.0083, pFDR=0.04). Excluding participants with psychiatric diagnoses produced similar results. The MEGA-GWAS identified a single SNP (rs12023073; p = 3.24 × 10-8) near IGSF21, a protein involved in inhibitory brain synapses; replication samples are needed to validate this result. A PRS for self-reported cannabis use (p = 0.00047, pFDR = 0.0053), but not self-reported risk-taking or psychiatric disorder status, predicted behavior on the BART in our MEGA-GWAS sample. The findings reveal polygenic architecture of risky decision-making as measured by the BART and highlight its overlap with cannabis use.

Pragmatic review of interventions to prevent catheter-associated urinary tract infections (CAUTIs) in adult inpatients. J Hosp Infect 2023; 136:55-74. [PMID: 37015257 DOI: 10.1016/j.jhin.2023.03.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 03/27/2023] [Accepted: 03/28/2023] [Indexed: 04/06/2023]
Abstract
BACKGROUND Urinary tract infections (UTIs) are one of the most common hospital-acquired complications. Insertion of a urinary catheter and the duration of catheterization are the main risk factors, with catheter-associated UTIs (CAUTIs) accounting for 70-80% of hospital-acquired UTIs. Guidance is available regarding the prevention of hospital-acquired CAUTIs; however, how best to operationalize this guidance remains a challenge. AIM To map and summarize the peer-reviewed literature on model-of-care interventions for the prevention of CAUTIs in adult inpatients. METHODS PubMed, CINAHL and SCOPUS were searched for articles that reported UTI, CAUTI or urinary catheter outcomes. Articles were screened systematically, data were extracted systematically, and interventions were classified by intervention type. FINDINGS This review included 70 articles. Interventions were classified as single component (N=19) or multi-component (N=51). Single component interventions included: daily rounds or activities (N=4), protocols and procedure changes (N=6), reminders and order sets (N=5), audit and feedback interventions (N=3), and education with simulation (N=1). Overall, daily catheter reviews and protocol and procedure changes demonstrated the most consistent effects on catheter and CAUTI outcomes. The components of multi-component interventions were categorized to map common elements and identify novel ideas. CONCLUSION A range of potential intervention options with evidence of a positive effect on catheter and CAUTI outcomes was identified. This is intended to provide a 'menu' of intervention options for local decision makers, enabling them to identify interventions that are relevant and feasible in their local setting.

Systematic development and feasibility testing of a multibehavioural digital prehabilitation intervention for patients approaching major surgery (iPREPWELL): A study protocol. PLoS One 2022; 17:e0277143.

Abstract
Improving outcomes for people undergoing major surgery, specifically reducing perioperative morbidity and mortality remains a global health challenge. Prehabilitation involves the active preparation of patients prior to surgery, including support to tackle risk behaviours that mediate and undermine physical and mental health and wellbeing. The majority of prehabilitation interventions are delivered in person, however many patients express a preference for remotely-delivered interventions that provide them with tailored support and the flexibility. Digital prehabilitation interventions offer scalability and have the potential to benefit perioperative healthcare systems, however there is a lack of robustly developed and evaluated digital programmes for use in routine clinical care. We aim to systematically develop and test the feasibility of an evidence and theory-informed multibehavioural digital prehabilitation intervention 'iPREPWELL' designed to prepare patients for major surgery. The intervention will be developed with reference to the Behaviour Change Wheel, COM-B model, and the Theoretical Domains Framework. Codesign methodology will be used to develop a patient intervention and accompanying training intervention for healthcare professionals. Training will be designed to enable healthcare professionals to promote, support and facilitate delivery of the intervention as part of routine clinical care. Patients preparing for major surgery and healthcare professionals involved with their clinical care from two UK National Health Service centres will be recruited to stage 1 (systematic development) and stage 2 (feasibility testing of the intervention). Participants recruited at stage 1 will be asked to complete a COM-B questionnaire and to take part in a qualitative interview study and co-design workshops. Participants recruited at stage 2 (up to twenty healthcare professionals and forty participants) will be asked to take part in a single group intervention study where the primary outcomes will include feasibility, acceptability, and fidelity of intervention delivery, receipt, and enactment. Healthcare professionals will be trained to promote and support use of the intervention by patients, and the training intervention will be evaluated qualitatively and quantitatively. The multifaceted and systematically developed intervention will be the first of its kind and will provide a foundation for further refinement prior to formal efficacy testing.

Abstract
Abstract
Background
Despite complete resection of mature ovarian teratoma, there remains a risk of metachronous contralateral disease with implications for further surgery and fertility. Current estimates of this risk are wide and practice regarding surveillance varies. We aimed to identify the incidence of metachronous contralateral disease in girls presenting with unilateral mature ovarian teratoma and to describe current follow-up.
Methods
Retrospective case note review was performed for all girls (< 17 years) undergoing surgery for histologically confirmed mature ovarian teratoma between 1998 and 2018. Data concerning initial hospital episode, follow-up, and further intervention were collected.
Results
Forty-five girls were identified with a median age of 10 years (range 1–16). Salpingo-oophorectomy (47%) and oophorectomy (36%) were the commonest operations. Median follow-up was 2 years (range 0–16 years) with surveillance ultrasonography performed in 49%. One case of metachronous contralateral teratoma (2%) was detected at 1 year, requiring oophorectomy and ovarian tissue cryopreservation.
Conclusions
This series has demonstrated a lower incidence of metachronous contralateral mature ovarian teratoma compared to previously published data. Postoperative surveillance is variable, and the true natural history of this condition remains incompletely understood. Prospective, multicentre investigation at national or international level is required to improve the evidence upon which to base safe standards of care.

Abstract
Abstract
BACKGROUND
Malignant paediatric nervous system tumours, such as medulloblastoma, ATRT and high-risk neuroblastoma commonly harbour tumour cells with stem-like features which are highly tumorigenic and resistant to conventional therapies. These tumours can exhibit high lethality and may result in severe sequelae that significantly affect paediatric patients' quality of life. Oncolytic virotherapy exploits viruses that preferentially infect and destroy tumour cells. These viruses present a unique advantage in targeting highly heterogeneous cancers as they possess a secondary mechanism of action, through which they induce an anti-tumoral immune response. The Zika virus (ZIKV) is capable of infecting and destroying aggressive human paediatric brain tumour and neuroblastoma cells in vitro. ZIKV effectively reduces brain tumour size in mice (xenograft model) and canines (naturally occurring) and can induce an immune response against canine brain tumours.
METHODS
Employing global expression omics profiling of ZIKV infection and mapping of viral protein-host protein interactions, we aim to elucidate the mechanisms which underpin ZIKVs therapeutic properties, both at the molecular and cellular pathway levels.
RESULTS
Through extensive transcriptome profiling of ZIKV-infected paediatric brain tumour, neuroblastoma and NPCs, we have identified a variety of pathways which are involved in the ZIKV oncolytic response in the tumour cells and its neuro-dysregulation of NPCs. Despite both brain tumour and neuroblastoma cells undergoing ZIKV-induced oncolysis, we observed there to be a heterogeneous response within these different tumour cells at the molecular level to lead to oncolysis. Additionally, the infected tumour cells demonstrate elevated immune system profiles which alludes to the immune response that ZIKV may raise within the patient’s body against the paediatric tumour. Analysing our findings alongside the neuro-dysregulation we observe in our ZIKV-infected NPCs is allowing us to build a safety profile for employing a ZIKV-based therapy, whilst contributing to the growing knowledge of Congenital ZIKV Syndrome.

Abstract
Abstract
Introduction/Objective
The process of metastasis is responsible for most cancer deaths. Identification of tumor cells circulating in blood (CTCs) has the potential to offer important information to patients and clinicians regarding disease status, longitudinal monitoring, remission status and assessment of patient prognosis, among others. However, currently CTC tests in the market are expensive and are not covered by medical insurance, making them unaffordable for most cancer patients. Legacy CTC technologies also require the use of expensive immunofluorescence microscopes and reagents, and are not easily implemented in standard clinical laboratory settings, thus preventing their use as standard of care. Onc-ADaPT™ Clinical Laboratories have explored a method to identify CTCs using the FDA cleared Parsortix® System (ANGLE plc, Guildford, UK) followed by standard cytology processing, staining and analysis, significantly reducing the cost of operations and increasing the likelihood of affordability to patients everywhere.
Methods/Case Report
The basic features of malignancy were listed by a Senior Cytologist (CT) and reviewed by another CT. Cancer cell lines were spiked into normal donor blood collected in Streck tubes. Non-spiked healthy volunteer blood was used to establish the background. The samples were then processed through the Parsortix® system producing 200µL suspension of separated cells. The harvest was then processed using Cytospin, stained with standard Pap Stain and reviewed with bright field microscopy by qualified CTs.
Results (if a Case Study enter NA)
Spiked tumor cells were identified and correctly categorized by the Cytologists. Non-spiked normal donor samples were negative for malignancy. Cells of interest were identified in the non-spiked HNV samples and classified as non-malignant (NOS). Using the training set, CTs later analyzed the available patient sample. The positive cancer patient sample showed cells with obvious characteristics of malignancy.
Conclusion
The basic characteristics of malignancy used for analysis of standard cytology specimens are adequate to identify CTCs using the established background to eliminate the NOS cells. CTC testing can be performed using the combination of Parsortix® System, standard cytology staining and analysis by qualified Cytologists.

Abstract
Mature ovarian teratoma has the potential to occur metachronously in the contralateral ovary. There are significant implications for fertility as bilateral oophorectomy may be indicated. In prepubertal girls, ovarian tissue cryopreservation (OTC) offers the only possibility of a future biological pregnancy but outcome data are limited. We present a case of prepubertal OTC in a 12 year old girl undergoing a second oophorectomy for metachronous contralateral mature teratoma. We offer a discussion of the challenges that emerged regarding peri-operative decision-making, balancing the need for safe oncological resection with the desire to preserve fertility.

Abstract
10002 Background: The BEACON phase II trial (NCT02308527) addressed a number of questions in children with relapsed/refractory high-risk neuroblastoma (RR-HRNB). Here we report the chemo-immunotherapy randomisation, assessing if anti-GD2 (dB) demonstrates activity when added to chemotherapy. Methods: Patients aged 1-21 years with RR-HRNB with adequate organ function and performance status were randomised in a 1:2 ratio to receive chemotherapy alone or with dB, given concurrently as a 7 day continuous infusion (10 mg/m2/24hr). As the trial had a factorial design, some patients were also randomised between chemotherapy regimens (temozolomide (T) versus Temozolomide-Topotecan (TTo); this randomisation closed soon after the dB randomisation opened and all patients subsequently received TTo chemotherapy. Cross-over to dB with topotecan and cyclophosphamide was allowed for patients randomised to chemotherapy alone who experienced disease progression. The primary outcome measure was best response (complete or partial) at any point during the first 6 courses of treatment, by RECIST or International Neuroblastoma Response Criteria for patients with measurable and evaluable disease respectively. Progression free and overall survival (PFS & OS) and safety were secondary outcomes. The success criterion for proceeding to a Phase 3 trial was a one-sided p-value (1p) less than 0.23 for Objective Response Rate (ORR). Results: From Aug 2019 to Feb 2021, 65 patients were randomised to chemotherapy alone (3 T, 19 TTo) or with dB (6 dBT, 37 dBTTo). Median age was 4 years; 48 and 17 had measurable and evaluable disease respectively; 29 and 36 had refractory and relapsed disease respectively; 19 had MYCN amplification. Baseline characteristics were balanced between arms. Response was assessable in all patients. The ORR was 18% with chemotherapy alone and 35% for patients receiving chemotherapy with dB (risk ratio 1.66, 80% confidence interval (CI) 0.9 to 3.06, 1p = 0.19). 1-year PFS was 27% for chemotherapy alone, and 57% for those receiving chemotherapy +dB (HR 0.63, 95% CI 0.32 to 1.25, p = 0.19). Twelve patients in the chemotherapy only arm crossed over to receive dB at progression. OS did not differ between the arms: HR = 0.99, 95% CI 0.42 to 2.36, p = 0.99. Nine (41%) patients receiving chemotherapy alone and 13 (30%) receiving chemotherapy plus dB had grade ≥3 toxicities (CTCAE v4.0). Neurotoxicities were more common in patients receiving dB compared to chemotherapy alone (Grade 1-2: 67.4% vs 13.6%, Grade 3: 9.3 vs 0%). Other toxicities were similar with and without dB. Conclusions: The Phase 2 success criterion for ORR was met and PFS is also encouraging. The addition of dB to temozolomide-based chemotherapy shows promising activity in patients with RR-HR-NB. Clinical trial information: NCT02308527.

Abstract
10039 Background: Children with relapsed and refractory neuroblastoma (RR-NBL) have poor outcomes. Early identification of children at greatest risk of relapse could mean timelier modifications of treatment to improve outcomes. High levels of adrenergic neuroblastoma mRNAs in blood of children with stage M neuroblastoma receiving frontline treatment predict poor outcome (Viprey PMID: 24590653). Since these markers have not been thoroughly studied in the RR-NBL population, we have prospectively evaluated the prognostic potential of the adrenergic neuroblastoma mRNAs paired-like homeobox 2B (PHOX2B ) and tyrosine hydroxylase (TH) in blood from children with RR-NBL treated in the BEACON-Neuroblastoma trial (NCT02308527). Methods: Blood samples collected at baseline from 88 children were analysed by reverse transcriptase polymerase chain reaction (RTqPCR) for PHOX2B and TH mRNAs. The prognostic power of these mRNAs was evaluated using Kaplan-Meier survival curves and Cox proportional hazards regression. Progression-free (PFS) and overall survival (OS) were calculated from the date that the blood sample was taken at screening to the date of an event; progression, disease recurrence, death or censored alive at the last clinical evaluation. Results: Of the children in this cohort, 58 (66%) had relapsed and 30 (34%) had refractory disease. Twenty-three (26%) had MYC-N amplified tumours. TH and PHOX2B mRNAs were detected in 55% and 60% of blood samples respectively; the correlation coefficient between TH and PHOX2B was 0.75. Higher levels of TH, PHOX2B mRNAs or both combined were associated with reduced PFS and OS (Table). For TH, median PFS for children with TH levels below the median was 12 months (95%CI, 4.6–13 months) versus 5.5 months (95%CI, 1.8–9.4 months) for those children with TH levels above the median. For PHOX2B, median PFS for children with PHOX2B levels below the median was 11.5 months (95%CI, 7.6–34 months), compared to 5.7 months (95%CI, 1.8–10.5 months) where levels were above the median. Conclusions: TH and PHOX2B mRNAs in blood collected at baseline identify children with refractory or relapsed neuroblastoma at greatest risk of progression or death. In the RR-NBL setting, this simple blood test could be used to stratify treatment strategies. Clinical trial information: NCT02308527. [Table: see text]

Maternity services response to the COVID-19 pandemic: how Public Health England guidance was implemented in practice. J Hosp Infect 2022; 129:214-218. [PMID: 35584730 PMCID: PMC9107387 DOI: 10.1016/j.jhin.2022.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 04/25/2022] [Accepted: 04/27/2022] [Indexed: 11/18/2022]
Abstract
Introduction The rapidly evolving COVID-19 pandemic required systemic change in how healthcare was delivered to minimize virus transmission whilst maintaining safe service delivery. Deemed at ‘moderate-high risk’, maternity patients are an important patient group that require consideration. Public Health England (PHE) issued national guidance on how to adjust these services. Aim To explore how maternity units in England implemented PHE guidance. Methods An online survey of 22 items was distributed to individuals that had worked on an England-based maternity unit during the COVID-19 pandemic. The questionnaire was designed and tested by the multidisciplinary research team. Data was collected from November 2020 to July 2021. Findings Forty-four participants across 33 maternity units responded. Ninety-three percent were able to test all women requiring an overnight stay for COVID-19. Only 27% reported birth partners were tested for COVID-19. Only 73% reported they were able to isolate all COVID-19-positive patients in single rooms. Eighty-four percent stated they were aware of current PHE guidance on personal protective equipment (PPE) and 82% felt ‘confident’ in donning/doffing of PPE. Priorities for the future include rapid testing and a focus on community service provision. Conclusions PHE COVID-19 guidance was implemented differently in maternity units across England due to the varying resources available at each trust leading to variable ability to test and isolate patients as recommended. More specific, tailored guidance for infection control measures against COVID-19 is needed for maternity settings due to their unique position.

Clinical Phenotype and Management of Severe Neurotoxicity Observed in Patients with Neuroblastoma Treated with Dinutuximab Beta in Clinical Trials. Cancers (Basel) 2022; 14:cancers14081919.

Abstract
Neurotoxicity is an off-tumour, on-target side effect of GD2-directed immunotherapy with monoclonal antibodies. Here, we report the frequency, management and outcome of patients enrolled in two prospective clinical trials who experienced severe neurotoxicity during immunotherapy with the anti-GD2 antibody dinutuximab beta (DB) administered as short-term infusion (HR-NBL1/SIOPEN study, randomisation R2, EudraCT 2006-001489-17) or as long-term infusion (HR-NBL1/SIOPEN study, randomisation R4, EudraCT 2006-001489-17 and LTI/SIOPEN study, EudraCT 2009-018077-31), either alone or with subcutaneous interleukin-2 (scIL-2). The total number of patients included in this analysis was 1102. Overall, 44/1102 patients (4.0%) experienced Grade 3/4 neurotoxicities (HR-NBL1 R2, 21/406; HR-NBL1 R4, 8/408; LTI study, 15/288), including 27 patients with severe neurotoxicities (2.5%). Events occurred predominantly in patients receiving combined treatment with DB and scIL-2. Neurotoxicity was treated using dexamethasone, prednisolone, intravenous immunoglobulins and, in two patients, plasmapheresis, which was highly effective. While neurological recovery was observed in 16 of 21 patients with severe neurotoxicities, 5/1102 (0.45%) patients experienced persistent and severe neurological deficits. In conclusion, severe neurotoxicity is most commonly observed in patients receiving DB with scIL-2. Considering the lack of clinical benefit for IL-2 in clinical trials so far, the administration of IL-2 alongside DB is not recommended.

Abstract
INTRODUCTION In any health system, choices must be made about the allocation of resources (budget), which are often scarce. Economics has defined frameworks to aid resource allocation, and program budgeting marginal analysis (PBMA) is one such framework. In principle, patient and public values can be incorporated into these frameworks, using techniques such as willingness to pay (WTP). However, this has not been done before, and few formal resource allocation processes have been undertaken in dentistry. This study aimed to undertake a PBMA with embedded WTP values in a national dental setting. METHODS The PBMA process was undertaken by a panel of participant-researchers representing commissioners, dentists, dental public health staff, and academics. The panel reviewed current allocations and generated a set of weighted criteria to evaluate services against. Services to be considered for removal and investment were determined by the panel and wider discussion and then scored against the criteria. Values from a nationally representative WTP survey of the public contributed to the scores for interventions. Final decisions on removal and investment were taken after panel discussion using individual anonymous electronic voting. RESULTS The PBMA process resulted in recommendations to invest in new program components to improve access to general dentists, care home dentistry, and extra support for dental public health input into local government decisions. Disinvestments were recommended in orthodontics and to remove routine scaling and polishing of teeth. DISCUSSION The PBMA process was successful in raising awareness of resource allocation issues. Implementation of findings will depend on the ability of decision makers to find ways of operationalizing the decisions. The process illustrates practical aspects of the process that future dental PBMAs could learn from. KNOWLEDGE TRANSFER STATEMENT This study illustrates a framework for resource allocation in dental health services and will aid decision makers in implementing their own resource allocation systems.

Abstract
There is increasing recognition that contralateral metachronous tumor may occur following treatment of unilateral mature ovarian teratoma. We aimed to define this risk to guide appropriate surveillance strategies. We undertook a systematic review of three large medical databases (Ovid Medline, Embase, and Cochrane Controlled Trials Register) to April 2020 using a defined search strategy. From 1831 articles retrieved, 23 were included, reporting 1101 girls with unilateral mature ovarian teratomas. The intensity and duration of follow-up varied between studies, with only five reporting close surveillance. Overall prevalence of metachronous contralateral mature teratoma was 2.1%, with a prevalence per study of 0%-23% (median 0%). Prevalence was higher (7%) among studies with more robust surveillance. These data suggest a small but real risk of metachronous contralateral tumors. Surveillance ultrasonography is proportionate and indicated alongside further prospective data collection to record the natural history and impact of surveillance in greater detail.

Abstract
BACKGROUND Findings are presented from the evaluation of Public Health England's (PHE) Prioritization Framework (PF) aimed to assist local authority commissioners with their public health investment and disinvestment decisions. The study explored the take up of the PF in three early adopter local authority settings. METHODS Semi-structured interviews (n = 30) across three local authorities supplemented by participant observation of workshops. RESULTS Participants acknowledged that the PF provided a systematic means of guiding priority-setting and one that encouraged transparency over investment and disinvestment decisions. The role performed by PHE and its regional teams in facilitating the process was especially welcomed and considered critical to the adoption process. However, uptake of the PF required a significant investment of time and commitment from public health teams at a time when resources were stretched. The impact of the political environment in the local government was a major factor determining the likely uptake of the PF. Ensuring committed leadership and engagement from senior politicians and officers was regarded as critical to success. CONCLUSIONS The study assessed the value and impact of PHE's PF tool in three early adopter local authorities. Further research could explore the value of the tool in aiding investment and disinvestment decisions and its impact on spending.

Abstract
Abstract
Aim: To evaluate guideline compliance of antibiotics prescription in Emergency Department (ED).
To improve documentation of antibiotic prescription.
To highlight the need for good antibiotic stewardship.
To optimise the use of antibiotics.
Method
A cross-sectional, retrospective patient record review was conducted regarding antibiotic prescription over 1 month in Sheffield Children’s Hospital ED. All antibiotic prescriptions over that period were collected. From the total number of prescriptions, a convenience sample of 100 prescriptions was selected to correlate their indications with local guidelines.
Results
A total of 290 prescriptions for 310 antibiotics were collected. The most frequent antibiotic prescribed was Penicillin V (26.7%), followed by Amoxicillin (21.3%), Co-amoxiclav (20.3%), and Flucloxacillin (16.5%). From the convenience sample, 12 antibiotics were prescribed inappropriately, with the most frequent being Co-amoxiclav (41.7%), followed by Penicillin V (25%), Amoxicillin and Flucloxacillin (both 16.7%). Overall, there has been good stewardship of antibiotic use with 88% of antibiotic prescribing conducted appropriately as per ED guidelines.
Conclusions
Antibiotic resistance is a growing concern, with one of the leading causes being inappropriate prescription of antibiotics. Adhering to local guidelines can help to prevent them from developing resistance. Adherence can be improved through induction and training of clinicians.

Abstract
10536 Background: We previously developed a risk factor model in HR-NBL1/SIOPEN patients treated without DB including age, LDH and metastatic site index (MSI). We tested if this score (Morgenstern, PBC 2018) would provide meaningful information in DB treated HR-NBL1/SIOPEN patients. Methods: High-risk patients (stage 4 ≥1yr.; stage 4 < 1yr. with MYCN amplification (MNA); stage 2, 3, 0-21y with MNA) received intensive induction, surgery, high dose therapy (HDT) and local radiotherapy (21Gy). Patients with a ≤9 months intervall till HDT/SCT, ≥ partial response prior and no progression received up to 5 cycles of 100mg/m2 DB: as short-term (STI: 5 days) or long-term infusion (LTI: 10 days ) ± 6 (STI) or 3 (LTI) x 106 IU/m2 subcutaneous interleukin 2 (scIL2 over 2 x 5 days) followed by 2 weeks of 160mg/m2 oral isotretinoin. Results: DB was used in 1018 patients [512 males; 89% Stage, 1% Stage 4s, 10% loc. MNA; 2.8 yrs median age at diagnosis] in 18 countries. STI was used in 61% patients, LTI in 39% and DB without scIL2 in 62% patients. 2-yrs. event-free (EFS)/overall survival (OS) was 0.65±0.02/0.78±0.01 and 5-yrs. EFS/OS of 0.56±0.02/0.63±0.02. 891/1018 patients were evaluable for risk factor analysis. EFS multivariate analysis included age, MSI, LDH ≥1250U/L, HDT typ, response prior DB, DB schedule and use of scIL2: only age > 1.5yrs.(p = 0.002) and MSI > 1 (p = 0.002) had independent prognostic prediction. If restricted to stage 4 only, LDH ≥1250U/L was also an independent factor (p = 0.049). Points were allocated in proportion to the log-cumulative hazard ratio (cHR): cHR for LDH > 1250U/L was 1.33 (score of 1), cHR for age > 5 years and metastatic site involvement (MSI) > 1 were 1.79 and 1.86 (scores of 2). Using the score (0 to 5) relevant risk groups can be identified: 5-yrs. EFS/OS for scores 0&1 are 0.80±0.06&0.77±0.04, score 2/3 are 0.58±0.03&0.57±0.04 and for scores 4/5 are 0.50±0.06&0.43±0.08. Conclusions: The score adds value in DB treatment groups as it differentiates prognostic subgroups facilitating decision making for future DB add on treatments. Clinical trial information: NCT01704716.

Abstract
National efforts are underway to prepare the UK National Health Service (NHS) for the COVID-19 pandemic; however, the efficacy of these interventions is unknown. In view of this, a cross-sectional survey of front-line healthcare workers (HCWs) at two large acute NHS hospital trusts in England was undertaken to assess their confidence and perceived level of preparedness for the virus. The survey found that there has been moderate success in readying HCWs to manage COVID-19, but that more still needs to be done, particularly in relation to educating HCWs about laboratory diagnostics.

Abstract
Background Antimicrobial resistance (AMR) is being recognized as a priority by healthcare organizations across the world. However, many children are managed on IV antimicrobials in hospital with very little consideration of antimicrobial stewardship issues. Objectives A nurse-led paediatric ambulatory outpatient parenteral antimicrobial therapy (OPAT) service, managing children with common infections being ambulated on short courses of IV antimicrobials, was introduced within Southampton Children’s Hospital in January 2018. We evaluated the impact of this service in terms of the quality of antimicrobial prescribing and timing of ambulation in children presenting with common infections. Methods All cases managed within the service were reviewed in two separate 2 month time periods: prior to introduction of the service (September–October 2016) and then prospectively after its introduction (September–October 2018). Results A total of 96% of IV antibiotic management decisions at 48 h were deemed appropriate in 2018, compared with 75% in 2016. A total of 64% of patients were ambulated on IV antibiotics at some point during their treatment course in 2018, compared with 19% in 2016. However, a significant proportion of antimicrobial decisions made at the point of presentation to hospital remained suboptimal in 2018. Conclusions Children are commonly managed with IV antibiotics in hospital. We demonstrate marked improvements in appropriate antimicrobial use through the introduction of a nurse-led ambulatory OPAT service. In addition, such a service can promote a greater proportion of children being ambulated from hospital, freeing up valuable inpatient beds and potentially delivering cost savings that can be used to fund such services.

Abstract
The third multistakeholder Paediatric Strategy Forum organised by ACCELERATE and the European Medicines Agency focused on immune checkpoint inhibitors for use in combination therapy in children and adolescents. As immune checkpoint inhibitors, both as monotherapy and in combinations have shown impressive success in some adult malignancies and early phase trials in children of single agent checkpoint inhibitors have now been completed, it seemed an appropriate time to consider opportunities for paediatric studies of checkpoint inhibitors used in combination. Among paediatric patients, early clinical studies of checkpoint inhibitors used as monotherapy have demonstrated a high rate of activity, including complete responses, in Hodgkin lymphoma and hypermutant paediatric tumours. Activity has been very limited, however, in more common malignancies of childhood and adolescence. Furthermore, apart from tumour mutational burden, no other predictive biomarker for monotherapy activity in paediatric tumours has been identified. Based on these observations, there is collective agreement that there is no scientific rationale for children to be enrolled in new monotherapy trials of additional checkpoint inhibitors with the same mechanism of action of agents already studied (e.g. anti-PD1, anti-PDL1 anti-CTLA-4) unless additional scientific knowledge supporting a different approach becomes available. This shared perspective, based on scientific evidence and supported by paediatric oncology cooperative groups, should inform companies on whether a paediatric development plan is justified. This could then be proposed to regulators through the available regulatory tools. Generally, an academic-industry consensus on the scientific merits of a proposal before submission of a paediatric investigational plan would be of great benefit to determine which studies have the highest probability of generating new insights. There is already a rationale for the evaluation of combinations of checkpoint inhibitors with other agents in paediatric Hodgkin lymphoma and hypermutated tumours in view of the activity shown as single agents. In paediatric tumours where no single agent activity has been observed in multiple clinical trials of anti-PD1, anti-PDL1 and anti-CTLA-4 agents as monotherapy, combinations of checkpoint inhibitors with other treatment modalities should be explored when a scientific rationale indicates that they could be efficacious in paediatric cancers and not because these combinations are being evaluated in adults. Immunotherapy in the form of engineered proteins (e.g. monoclonal antibodies and T cell engaging agents) and cellular products (e.g. CAR T cells) has great therapeutic potential for benefit in paediatric cancer. The major challenge for developing checkpoint inhibitors for paediatric cancers is the lack of neoantigens (based on mutations) and corresponding antigen-specific T cells. Progress critically depends on understanding the immune macroenvironment and microenvironment and the ability of the adaptive immune system to recognise paediatric cancers in the absence of high neoantigen burden. Future clinical studies of checkpoint inhibitors in children need to build upon strong biological hypotheses that take into account the distinctive immunobiology of childhood cancers in comparison to that of checkpoint inhibitor responsive adult cancers.

Abstract
Abstract
Background
Findings are presented from the evaluation of Public Health England’s (PHE) new Prioritisation Framework (PF) conducted between September 2017 and December 2018 aimed to help local authority commissioners with their public health investment and disinvestment decisions. The study explored the take up of the PF in three early adopter local authority settings.
Methods
Data collection was based on semi-structured interviews (n = 30) across three local authorities supplemented by participant observation of workshops and data concerning the implementation process as well as spend and outcomes both before and, where possible, after using the PF.
Results
Participants acknowledged that the PF provided a systematic way to guide prioritisation decisions and one that encouraged transparency over investment and disinvestment decisions. The role performed by PHE and its regional teams in facilitating the process was especially welcomed and considered to be critical to the adoption process. However, uptake of the PF required a significant investment of time and commitment from public health teams at a time when resources were stretched. The impact of the political environment in local government was a major factor determining the likely uptake of the PF. Ensuring committed leadership and engagement from senior politicians and officers was regarded as critical to success.
Conclusions
The study assessed the value of the PF and the processes surrounding its implementation and use. Further research could further explore the value of the tool in aiding investment and disinvestment decisions and its impact on spending.
Key messages
The PF provides a platform for engaged and informed deliberation about priorities and does so in an open, structured and transparent manner. Organisational and political context in which prioritisation occur shape the adoption of the PF tool.

Host identification in unfed ticks from stable isotope compositions (δ 13 C and δ 15 N). MEDICAL AND VETERINARY ENTOMOLOGY 2019; 33:360-366. [PMID: 30883848 DOI: 10.1111/mve.12372] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 01/21/2019] [Accepted: 02/08/2019] [Indexed: 06/09/2023]
Abstract
Determination of the ratios of natural stable isotopes (13 C/12 C and 15 N/14 N) in unfed Ixodes ricinus nymphs and adults, which, in their previous stage, fed on captive wild rodents (Apodemus sylvaticus and Myodes glareolus), wild birds (Parus major and Cyanistes caeruleus) or domestic ruminants (Ovis aries and Bos taurus), demonstrated that it is possible to identify each host category with confidence. First, the tick-blood spacing, which is the difference between values obtained from ticks and the blood of hosts that they had fed on in the previous stage, was consistent (152 spacings investigated from 15 host individuals in total). Second, potential confounding factors (tick age and sex) did not affect the discriminatory power of the isotope patterns, nor did different rearing conditions (room temperature vs. 4 °C) or the duration of development (maximum of 430 days). The findings that the tick-blood isotope spacings, across a diverse range of hosts, were similar and predictable, and that confounders had little or no effect on this, strongly support the usage of the isotope approach. Because each of the host categories has a different role in the population dynamics of I. ricinus and in tick-borne pathogen ecology, the method described here has great potential for the clarification of tick and tick-borne pathogen ecology in the field.
