Problem-solving processes for central venous catheter occlusion within pediatric cancer care: A qualitative study.

PURPOSE: Central venous access devices play a crucial role in healthcare settings. However, there is concern regarding the high incidence of blockages occurring before the completion of treatments and existing guidelines for occlusion management are not consistently followed. To explore the decision-making and problem-solving process of occlusion management and identify enablers and barriers to implementing evidence for occlusion management in pediatric cancer care. METHODS: A qualitative design with individual semi-structured interviews. Participants were selected by purposeful sampling from a tertiary-referral pediatric facility, and semi-structured interviews were conducted. RESULTS: A total of 13 clinicians and 5 parents were interviewed. The thematic analysis revealed four main decision-making/problem-solving themes: 1) clinical reasoning and judgement for central venous access devices occlusion, 2) capability in central venous access devices occlusion management, 3) colleague collaboration in the escalation process and 4) lack of adequate support to manage the occlusion. This study identified positive and negative influences on the problem-solving process, including clinicians' psychological capabilities, social and physical resources, and beliefs about consequences. CONCLUSION: This study found that clinicians in pediatric cancer care were able to manage central venous access device occlusions using clinical reasoning and judgment skills, which may conflict with evidence-based practices. The study confirmed the importance of a team approach and prior experience in managing central venous access devices in pediatric oncology settings and identified potential conflicts between clinician decisions based on the patient's current and anticipated conditions and implementation of evidence-based practice. Improving documentation and providing visual aids could benefit clinicians' problem-solving processes.

High Target Homology Does Not Guarantee Inhibition: Aminothiazoles Emerge as Inhibitors of Plasmodium falciparum.

In this study, we identified three novel compound classes with potent activity against Plasmodium falciparum, the most dangerous human malarial parasite. Resistance of this pathogen to known drugs is increasing, and compounds with different modes of action are urgently needed. One promising drug target is the enzyme 1-deoxy-d-xylulose-5-phosphate synthase (DXPS) of the methylerythritol 4-phosphate (MEP) pathway for which we have previously identified three active compound classes against Mycobacterium tuberculosis. The close structural similarities of the active sites of the DXPS enzymes of P. falciparum and M. tuberculosis prompted investigation of their antiparasitic action, all classes display good cell-based activity. Through structure-activity relationship studies, we increased their antimalarial potency and two classes also show good metabolic stability and low toxicity against human liver cells. The most active compound 1 inhibits the growth of blood-stage P. falciparum with an IC50 of 600 nM. The results from three different methods for target validation of compound 1 suggest no engagement of DXPS. All inhibitor classes are active against chloroquine-resistant strains, confirming a new mode of action that has to be further investigated.

Phase 1 Open-Label Dose Escalation Trial for the Development of a Human Bacillus Calmette-Guérin Challenge Model for Assessment of Tuberculosis Immunity In Vivo.

BACKGROUND: A controlled human infection model for assessing tuberculosis (TB) immunity can accelerate new vaccine development. METHODS: In this phase 1 dose escalation trial, 92 healthy adults received a single intradermal injection of 2 × 106 to 16 × 106 colony-forming units of Bacillus Calmette-Guérin (BCG). The primary endpoints were safety and BCG shedding as measured by quantitative polymerase chain reaction, colony-forming unit plating, and MGIT BACTEC culture. RESULTS: Doses up to 8 × 106 were safe, and there was evidence for increased BCG shedding with dose escalation. The MGIT time-to-positivity assay was the most consistent and precise measure of shedding. Power analyses indicated that 10% differences in MGIT time to positivity (area under the curve) could be detected in small cohorts (n = 30). Potential biomarkers of mycobacterial immunity were identified that correlated with shedding. Transcriptomic analysis uncovered dose- and time-dependent effects of BCG challenge and identified a putative transcriptional TB protective signature. Furthermore, we identified immunologic and transcriptomal differences that could represent an immune component underlying the observed higher rate of TB disease incidence in males. CONCLUSIONS: The safety, reactogenicity, and immunogenicity profiles indicate that this BCG human challenge model is feasible for assessing in vivo TB immunity and could facilitate the vaccine development process.

VIKING II, a worldwide observational cohort of volunteers with northern isles ancestry.

Introduction: The purpose of VIKING II is to create an observational cohort of volunteers with ancestry from the Northern Isles of Scotland, primarily for identifying genetic variants influencing disease. The new online protocol is separate to, but follows on from, earlier genetic epidemiological clinic-based studies in the isolated populations of Orkney and Shetland. These populations are favourable for the study of rarer genetic variants due to genetic drift, the large number of relatives, and availability of pedigree information. They are known to be genetically distinct from mainland British populations. Methods and analysis: Online methods are being used to recruit ~4,000 people who have Northern Isles ancestry, living anywhere in the world. The option for participants to have actionable genetic results returned is offered. Consent will be taken electronically. Data will be collected at baseline through an online questionnaire and longitudinally through linkage to NHS data in the electronic health record. The questionnaire collects a variety of phenotypes including personal and family health. DNA will be extracted from saliva samples then genome-wide genotyped and exome sequenced. VIKING II aims to capitalise on the special features of the Northern Isles populations to create a research cohort that will facilitate the analysis of genetic variants associated with a broad range of traits and disease endpoints, including otherwise rare variants that have drifted to high frequency in these populations. Ethics and dissemination: The South East Scotland Research Ethics Committee gave the study a favourable opinion. VIKING II is sponsored by the University of Edinburgh and NHS Lothian. Summary research findings will be disseminated to participants and funding bodies, presented at conferences and reported in peer-reviewed publications. Article summary: Strengths and limitations of this studyDetailed data and biological sample collection of research volunteers with unique ancestry.Consent for access to routinely collected clinical EHR data and for future re-contact, providing a longitudinal component.Optional consent for return of actionable genetic results.~4,000 participants is a relatively small number for certain types of genetic analyses, so the cohort is underpowered on its own, in some study designs.Resources to maintain the cohort, and to store data and DNA samples, are significant, with sustainability dependent on infrastructure support and funding.

MEPicides: α,ß-unsaturated Fosmidomycin N-Acyl Analogs as Efficient Inhibitors of Plasmodium falciparum 1-Deoxy-d-xylulose-5-phosphate reductoisomerase.

Malaria, a mosquito-borne disease caused by several parasites of the Plasmodium genus, remains a huge threat to global public health. There are an estimated 0.5 million malaria deaths each year, mostly among African children. Unlike humans, Plasmodium parasites and a number of important pathogenic bacteria employ the methyl erythritol phosphate (MEP) pathway for isoprenoid synthesis. Thus, the MEP pathway represents a promising set of drug targets for antimalarial and antibacterial compounds. Here, we present new unsaturated MEPicide inhibitors of 1-deoxy-d-xylulose-5-phosphate reductoisomerase (DXR), the second enzyme of the MEP pathway. A number of these compounds have demonstrated robust inhibition of Plasmodium falciparum DXR, potent antiparasitic activity, and low cytotoxicity against HepG2 cells. Parasites treated with active compounds are rescued by isopentenyl pyrophosphate, the product of the MEP pathway. With higher levels of DXR substrate, parasites acquire resistance to active compounds. These results further confirm the on-target inhibition of DXR in parasites by the inhibitors. Stability in mouse liver microsomes is high for the phosphonate salts, but remains a challenge for the prodrugs. Taken together, the potent activity and on-target mechanism of action of this series further validate DXR as an antimalarial drug target and the α,ß-unsaturation moiety as an important structural component.

Diagnostic yield, safety, and outcomes of Head-to-pelvis sudden death CT imaging in post arrest care: The CT FIRST cohort study.

AIM: Our aim was to test whether a head-to-pelvis CT scan improves diagnostic yield and speed to identify causes for out of hospital circulatory arrest (OHCA). METHODS: CT FIRST was a prospective observational pre-/post-cohort study of patients successfully resuscitated from OHCA. Inclusion criteria included unknown cause for arrest, age >18 years, stability to undergo CT, and no known cardiomyopathy or obstructive coronary artery disease. A head-to-pelvis sudden death CT (SDCT) scan within 6 hours of hospital arrival was added to the standard of care for patients resuscitated from OHCA (post-cohort) and compared to standard of care (SOC) alone (pre-cohort). The primary outcome was SDCT diagnostic yield. Secondary outcomes included time to identifying OHCA cause and time-critical diagnoses, SDCT safety, and survival to hospital discharge. RESULTS: Baseline characteristics between the SDCT (N = 104) and the SOC (N = 143) cohorts were similar. CT scans (either head, chest, and/or abdomen) were ordered in 74 (52%) of SOC patients. Adding SDCT scanning identified 92% of causes for arrest compared to 75% (SOC-cohort; p value < 0.001) and reduced the time to diagnosis by 78% (SDCT 3.1 hours, SOC alone 14.1 hours, p < 0.0001). Identification of critical diagnoses was similar between cohorts, but SDCT reduced delayed (>6 hours) identification of critical diagnoses by 81% (p < 0.001). SDCT safety endpoints were similar including acute kidney injury. Patient survival to discharge was similar between cohorts. DISCUSSION: SDCT scanning early after OHCA resuscitation safely improved the efficiency and diagnostic yield for causes of arrest compared to the standard of care alone.

Care at Your Fingertips: Codesign, Development, and Evaluation of the Oncology Hub App for Remote Symptom Management in Pediatric Oncology.

PURPOSE: To codesign, develop, and evaluate a smartphone app that includes patient-reported measures of symptoms and real-time advice in children's cancer. METHODS: The Oncology Hub is a comprehensive approach to symptom management that includes a suite of codesigned tools and resources including clinical algorithms to determine the level of concern, symptom management advice, and resources for families of children with cancer. The evaluation involved Think Aloud interviews with parent and adolescent patients to complete tasks in the app as well as a User Experience questionnaire (score range, 0-120) and qualitative feedback. The accuracy of algorithms was determined by repeated testing of inputs and outputs over 4 weeks. RESULTS: Design and wireframes were iteratively refined through consultation with parents and adolescents confirming the final design. Beta testing evaluation was then completed by 25 participants including two adolescents. Across all participants, 84% of tasks were easy to navigate, and the Oncology Hub demonstrated high usability, usefulness, and acceptability with participants' scores ranging between 90 and 120 (mean = 112.2, standard deviation = 9.43). Qualitative feedback was positive. Testing of algorithms identified inconsistencies in understanding between clinical research and coding teams; refinements were made until the expected response notifications were returned with 100% accuracy. CONCLUSION: Technology offers new ways to think about how clinicians and families communicate and share information to harness the best of community and hospital services. Understanding how information is exchanged using health apps, and how this affects clinical workflow is critical to successful implementation, and optimizing symptom assessment and management in children with cancer.

Motivation to train during a pandemic: The role of fitness resources, mental health, and motivational profiles among student-athletes in team sports.

The sporting season across post-secondary institutions was canceled in March 2020 due to COVID-19, and student-athletes had to maintain their training at home. It is unclear what personal and contextual factors facilitated student-athletes' ability to maintain their training routines at home when social distancing and lockdown (SD/L) policies were put in place. Our cross-sectional study of 433 student-athletes examined (a) how athletes adapted their training, (b) what training barriers they experienced, (c) whether motivational profiles were associated with differences in training behaviors and mental health, and (d) what variables predicted athletes' motivation to train during this prolonged offseason. Student-athletes across Canada were recruited to complete an online survey between August and September 2020. Results showed that athletes significantly reduced their training load and intensity, with approximately 25% exercising two or fewer days a week. Barriers to training included limited access to fitness resources and equipment, having inconsistent training schedules, and experiencing emotional distractions, with some of these barriers more common among female athletes than male athletes. For motivation profiles, athletes with higher levels of intrinsic motivation tended to maintain the intensity of their workouts and experienced lower mood disturbance. A hierarchical multiple regression revealed that being male, being younger, having higher levels of intrinsic and introjected motivation, having access to fitness resources, maintaining a steady training schedule, having fewer emotional distractions, and lower mood disturbance were significant predictors to being motivated to train during the pandemic. We discuss strategies coaches and trainers can implement to best support their student-athletes.

A Case of Giant Cell Arteritis With a Normal Erythrocyte Sedimentation Rate (ESR) Post ChAdOx1 nCoV-19 Vaccination.

Giant cell arteritis (GCA) has been reported post the coronavirus disease 2019 (COVID-19) vaccination, especially with the mRNA vaccine. A normal erythrocyte sedimentation rate (ESR) is seen in some GCA patients. This report describes a 68-year-old gentleman who presented with a right-sided temporal headache for three weeks, starting three to five days after his second dose of the ChAdOx1 nCoV-19 vaccine, a viral vector vaccine, which was given seven weeks post the first dose. On presentation, he developed blurred vision in the left eye, and it progressed to complete vision loss four days later. He also had episodes of blurred vision in the right eye. The blood test showed a mildly elevated C-reactive protein of 29 mg/L and a normal erythrocyte sedimentation rate (ESR) of 4 mm/hr. Optical coherence tomography showed anterior ischaemic optic neuropathy in the left eye and retinal ischemia in the right eye. Bilateral giant cell arteritis (GCA) was confirmed on temporal artery biopsy. He was treated with methylprednisolone pulse therapy followed by prednisolone. He re-presented with intermittent blurry vision in the right eye three months later. He was treated with methylprednisolone pulse therapy again, followed by prednisolone, aspirin, and tocilizumab. This case describes a patient who developed GCA post ChAdOx1 nCoV-19 vaccination with a normal ESR. Further studies are needed to investigate this relationship as causal or incidental and the likelihood of low-level inflammatory makers in such a situation.

A Case of COVID-19 With Myasthenic Crisis.

Coronavirus disease 2019 (COVID-19) infection can increase the risk of myasthenic crisis. Dexamethasone has been widely used to manage severe COVID-19 infection. Paradoxically, steroids are effective for treating myasthenia gravis; however, when they are started in high doses, there is an associated risk of steroid-induced exacerbation. This case report describes an 86-year-old male with seropositive generalised myasthenia gravis, whose course had been stable for years. At the time of his COVID-19 diagnosis, he was on pyridostigmine and prednisolone 10 mg daily. He was treated with IV dexamethasone 6 mg daily, remdesivir, and antibiotics. On day 10 of admission, he had a sudden deterioration with a Glasgow Coma Scale (GCS) score of 3. Arterial blood gas (ABG) showed a new type 2 respiratory failure suggesting myasthenic crisis. Although his ABG improved after commencing bilevel positive airway pressure (BiPAP), his condition continued to deteriorate and he died the next day. A decision not to intubate and ventilate had been made given his poor clinical state and low chance of recovery. His myasthenic crisis was likely precipitated by the COVID-19 infection, although steroids, azithromycin, and doxycycline also have the potential to cause the worsening of myasthenia gravis. Further studies are needed to evaluate the efficacy and risk of steroid use in this patient population. Ventilatory failure may occur insidiously and is often difficult to detect, especially in elderly and delirious patients in whom performing a neurological examination can be difficult. Regular ABG and bedside measures of forced vital capacity may be considered to monitor the development of type 2 respiratory failure.

Major Role for Cellular MicroRNAs, Long Noncoding RNAs (lncRNAs), and the Epstein-Barr Virus-Encoded BART lncRNA during Tumor Growth In Vivo.

This study assessed the effects of Epstein-Barr virus (EBV) and one form of virally encoded BART long noncoding RNAs (lncRNAs) on cellular expression in epithelial cells grown in vitro and as tumors in vivo determined by high-throughput RNA sequencing of mRNA and small RNAs. Hierarchical clustering based on gene expression distinguished the cell lines from the tumors and distinguished the EBV-positive tumors and the BART tumors from the EBV-negative tumors. EBV and BART expression also induced specific expression changes in cellular microRNAs (miRs) and lncRNAs. Multiple known and predicted targets of the viral miRs, the induced cellular miRs, and lncRNAs were identified in the altered gene set. The changes in expression in vivo indicated that the suppression of growth pathways in vivo reflects increased expression of cellular miRs in all tumors. In the EBV and BART tumors, many of the targets of the induced miRs were not changed and the seed sequences of the nonfunctional miRs were found to have homologous regions within the BART lncRNA. The inhibition of these miR effects on known targets suggests that these induced miRs have reduced function due to sponging by the BART lncRNA. This composite analysis identified the effects of EBV on cellular miRs and lncRNAs with a functional readout through identification of the simultaneous effects on gene expression. Major shifts in gene expression in vivo are likely mediated by effects on cellular noncoding RNAs. Additionally, a predicted property of the BART lncRNA is to functionally inhibit the induced cellular miRs. IMPORTANCE This study identified the total effects of EBV and a viral long noncoding RNA (BART lncRNA) on cellular RNA expression when grown as cells in culture and when grown as tumors in immunodeficient mice. The effects on cellular mRNA expression, lncRNA expression, and cellular and viral miR expression were determined using next-generation sequencing (NGS) and bioinformatics functional analysis. Many cellular growth pathways that are activated during growth in culture are decreased during growth as tumors. This study shows that these changes in expression are accompanied by induction of cellular-growth-inhibitory miRs. However, in the EBV tumors and in tumors expressing the BART lncRNA, many of the known targets of the inhibitory miRs are not affected. Regions of strong homology to the seed sequences of these miRs were identified in the BART lncRNA. These findings suggest that the BART lncRNA functions as a sponge for growth-inhibitory miRs.

Routine Catheter Lock Solutions in Pediatric Cancer Care: A Pilot Randomized Controlled Trial of Heparin vs Saline.

BACKGROUND: Central venous access devices (CVADs) are integral to cancer care provision. Despite the high prevalence of CVAD complications in children with cancer, preventative strategies are understudied. OBJECTIVE: The aim of this study was to assess study feasibility, occlusive events, thrombolytic use, adverse events, and direct costs of catheter lock solutions. METHODS: A single-center, parallel-group, pilot randomized controlled trial was undertaken at a tertiary-referral pediatric hospital in Australia. Children 18 years or younger with an oncological or malignant hematological condition and a CVAD were eligible. Participants were 1:1 randomized to (1) normal or (2) heparinized (10-100 U/mL; CVAD-type dependent) saline lock solutions. RESULTS: Of 217 children assessed for eligibility, 61 were recruited and randomized to normal (n = 30; 3850 CVAD days) or heparinized (n = 31; 4036 CVAD days) saline. Eligibility (52%) and recruitment (54%) feasibility targets were not met. Protocol adherence was high (95% assessments), with no attrition. Parent/clinician satisfaction of interventions was high (median, 10/10 clinicians/parents). Complete CVAD occlusion occurred in heparin only (n = 2, 6.7% CVADs; incidence rate [IR], 0.49/1000 CVAD days [0.06-1.78]). Central venous access device partial occlusion was detected in 23.3% of CVADs in heparin (n = 7; IR, 2.73/1000 CVAD days [1.36-4.87]) and 13.8% of CVADs in normal saline (n = 4; IR, 2.59/1000 CVAD days [1.24-4.77]). Thrombolytic agents were used in 16.7% heparin (5 CVADs) and 3.5% normal saline (1 CVAD). Adverse events did not differ between groups. CONCLUSION: Multisite randomized controlled trials examining CVAD locks are safe, but strategies and resources to increase recruitment and eligibility are required. IMPLICATIONS FOR PRACTICE: Both routine CVAD lock solutions seem safe but may not prevent all forms of CVAD-associated harm.

From graphene to graphene oxide: the importance of extended topological defects.

Graphene oxide (GO) represents a complex family of materials related to graphene: easy to produce in large quantities, easy to process, and convenient to use as a basis for further functionalization, with the potential for wide-ranging applications such as in nanocomposites, electronic inks, biosensors and more. Despite their importance, the key structural traits of GO, and the impact of these traits on properties, are still poorly understood due to the inherently berthollide character of GO which complicates the establishment of clear structure/property relationships. Widely accepted structural models of GO frequently neglect the presence of extended topological defects, structural changes to the graphene basal plane that are not removed by reduction methods. Here, a combination of experimental approaches and molecular simulations demonstrate that extended topological defects are a common feature across GO and that the presence of these defects strongly influences the properties of GO. We show that these extended topological defects are produced following even controlled 'gentle' functionalization by atomic oxygen and are comparable to those obtained by a conventional modified Hummers' method. The presence of the extended topological defects is shown to play an important role in the retention of oxygen functional groups after reduction. As an exemplar of their effect on the physical properties, we show that the GO sheets display a dramatic decrease in strength and stiffness relative to graphene and, due to the presence of extended structural defects, no improvement is seen in the mechanical properties after reduction. These findings indicate the importance of extended topological defects to the structure and properties of functionalized graphene, which merits their inclusion as a key trait in simple structural models of GO.

The Plasmodium falciparum ABC transporter ABCI3 confers parasite strain-dependent pleiotropic antimalarial drug resistance.

Widespread Plasmodium falciparum resistance to first-line antimalarials underscores the vital need to develop compounds with novel modes of action and identify new druggable targets. Here, we profile five compounds that potently inhibit P. falciparum asexual blood stages. Resistance selection studies with three carboxamide-containing compounds, confirmed by gene editing and conditional knockdowns, identify point mutations in the parasite transporter ABCI3 as the primary mediator of resistance. Selection studies with imidazopyridine or quinoline-carboxamide compounds also yield changes in ABCI3, this time through gene amplification. Imidazopyridine mode of action is attributed to inhibition of heme detoxification, as evidenced by cellular accumulation and heme fractionation assays. For the copy-number variation-selecting imidazopyridine and quinoline-carboxamide compounds, we find that resistance, manifesting as a biphasic concentration-response curve, can independently be mediated by mutations in the chloroquine resistance transporter PfCRT. These studies reveal the interconnectedness of P. falciparum transporters in overcoming drug pressure in different parasite strains.

Granzyme A Produced by γ9δ2 T Cells Activates ER Stress Responses and ATP Production, and Protects Against Intracellular Mycobacterial Replication Independent of Enzymatic Activity.

Mycobacterium tuberculosis (Mtb), the pathological agent that causes tuberculosis (TB) is the number one infectious killer worldwide with one fourth of the world's population currently infected. Data indicate that γ9δ2 T cells secrete Granzyme A (GzmA) in the extracellular space triggering the infected monocyte to inhibit growth of intracellular mycobacteria. Accordingly, deletion of GZMA from γ9δ2 T cells reverses their inhibitory capacity. Through mechanistic studies, GzmA's action was investigated in monocytes from human PBMCs. The use of recombinant human GzmA expressed in a mammalian system induced inhibition of intracellular mycobacteria to the same degree as previous human native protein findings. Our data indicate that: 1) GzmA is internalized within mycobacteria-infected cells, suggesting that GzmA uptake could prevent infection and 2) that the active site is not required to inhibit intracellular replication. Global proteomic analysis demonstrated that the ER stress response and ATP producing proteins were upregulated after GzmA treatment, and these proteins abundancies were confirmed by examining their expression in an independent set of patient samples. Our data suggest that immunotherapeutic host interventions of these pathways may contribute to better control of the current TB epidemic.

Structure-guided microbial targeting of antistaphylococcal prodrugs.

Carboxy ester prodrugs are widely employed to increase oral absorption and potency of phosphonate antibiotics. Prodrugging can mask problematic chemical features that prevent cellular uptake and may enable tissue-specific compound delivery. However, many carboxy ester promoieties are rapidly hydrolyzed by serum esterases, limiting their therapeutic potential. While carboxy ester-based prodrug targeting is feasible, it has seen limited use in microbes as microbial esterase-specific promoieties have not been described. Here we identify the bacterial esterases, GloB and FrmB, that activate carboxy ester prodrugs in Staphylococcus aureus. Additionally, we determine the substrate specificities for FrmB and GloB and demonstrate the structural basis of these preferences. Finally, we establish the carboxy ester substrate specificities of human and mouse sera, ultimately identifying several promoieties likely to be serum esterase-resistant and microbially labile. These studies will enable structure-guided design of antistaphylococcal promoieties and expand the range of molecules to target staphylococcal pathogens.

Improving management of fever in neutropenic children with cancer across multiple sites.

OBJECTIVE: To evaluate the effectiveness of a clinical pathway in achieving antibiotic administration in less than 60 minutes for children with cancer, presenting with fever and neutropenia. Secondary objectives were to determine association between time to antibiotics (TTA) and other variables including fever duration, location of care and intravenous access types. METHODS: Following introduction of the clinical pathway, we collected prospective data about management of all cases that did and did not use the pathway across multiple sites over 16 months. A follow-up audit was conducted after 12 months. RESULTS: We evaluated a total of 453 presentations. Use of the clinical pathway was significantly associated with achieving TTA in less than 60 minutes (RR 0.69, 95% CI 0.56-0.85, p = <0.001). Despite varying use of the pathway over time, the median time to antibiotics was achieved in both the initial study period (57 minutes) and sustained at follow-up (60 minutes). TTA was also associated with types of intravenous access device and location of care and with length of stay. We did not find any association between TTA and any other variables. CONCLUSION: Clinical pathways improve fever management in this patient cohort. Ongoing education and auditing to identify factors which impact processes of care are necessary.

Practical reflections on a collaboration with healthcare consumers on the development of a simulation.

Background: Healthcare simulations generate moments of 'cultural compression' through which we transmit core values about our professional identities and the families we care for. The engagement of healthcare consumers in this process is useful to evaluate the values we transmit and ensure authenticity in the narratives we share. Methods: A simulation package on febrile neutropenia and port access was written by healthcare staff in consultation with the parent of a child with leukaemia. Healthcare consumer review was focused on the representation of the simulated parent within the simulation scripts. The child and his mother assisted in the development of supportive video resources on family perspectives on port access and demonstration of the procedure. Results: The involvement of healthcare consumers in the development of the scenario had positive impact on the design and the supportive resources, both of which created opportunities for patient advocacy and reinforced the centrality of healthcare consumers within the healthcare team. Conclusions: Healthcare consumer collaboration in scenario design was achievable and impactful without significant increased cost. We hope to promote the benefits of healthcare consumer consultation in simulation design to improve the pursuit of educational and cultural learning objectives.

TeenCovidLife: a resource to understand the impact of the COVID-19 pandemic on adolescents in Scotland.

TeenCovidLife is part of Generation Scotland's CovidLife projects, a set of longitudinal observational studies designed to assess the psychosocial and health impacts of the COVID-19 pandemic. TeenCovidLife focused on how adolescents in Scotland were coping during the pandemic. As of September 2021, Generation Scotland had conducted three TeenCovidLife surveys. Participants from previous surveys were invited to participate in the next, meaning the age ranges shifted over time. TeenCovidLife Survey 1 consists of data from 5,543 young people age 12 to 17, collected from 22 May to 5 July 2020, during the first school closures period in Scotland. TeenCovidLife Survey 2 consists of data from 2,245 young people aged 12 to 18, collected from 18 August to 14 October 2020, when the initial lockdown measures were beginning to ease, and schools reopened in Scotland. TeenCovidLife Survey 3 consists of data from 597 young people age 12 to 19, collected from 12 May to 27 June 2021, a year after the first survey, after the schools returned following the second lockdown in 2021. A total of 316 participants took part in all three surveys. TeenCovidLife collected data on general health and well-being, as well as topics specific to COVID-19, such as adherence to COVID-19 health guidance, feelings about school closures, and the impact of exam cancellations. Limited work has examined the impact of the COVID-19 pandemic on young people. TeenCovidLife provides relevant and timely data to assess the impact of the pandemic on young people in Scotland. The dataset is available under authorised access from Generation Scotland; see the Generation Scotland website for more information.
