Abstract
Ewing sarcoma (ES) is an aggressive cancer diagnosed in adolescents and young adults. The fusion oncoprotein (EWSR1::FLI1) that drives Ewing sarcoma is known to downregulate TGFBR2 expression (part of the TGFβ receptor). Because TGFBR2 is downregulated, it was thought that TGFβ likely plays an inconsequential role in Ewing biology. However, the expression of TGFβ in the Ewing tumor immune microenvironment (TIME) and functional impact of TGFβ in the TIME remains largely unknown given the historical lack of immunocompetent preclinical models. Here, we use single-cell RNAseq analysis of human Ewing tumors to show that immune cells, such as NK cells, are the largest source of TGFβ production in human Ewing tumors. We develop a humanized (immunocompetent) mouse model of ES and demonstrate distinct TME signatures and metastatic potential in these models as compared to tumors developed in immunodeficient mice. Using this humanized model, we study the effect of TGFβ inhibition on the Ewing TME during radiation therapy, a treatment that both enhances TGFβ activation and is used to treat aggressive ES. Utilizing a trivalent ligand TGFβ TRAP to inhibit TGFβ, we demonstrate that in combination with radiation, TGFβ inhibition both increases ES immune cell infiltration and decreases lung metastatic burden in vivo . The culmination of these data demonstrates the value of humanized models to address immunobiologic preclinical questions in Ewing sarcoma and suggests TGFβ inhibition as a promising intervention during radiation therapy to promote metastatic tumor control.

De Novo Purine Metabolism is a Metabolic Vulnerability of Cancers with Low p16 Expression. CANCER RESEARCH COMMUNICATIONS 2024; 4:1174-1188. [PMID: 38626341 PMCID: PMC11064835 DOI: 10.1158/2767-9764.crc-23-0450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 03/04/2024] [Accepted: 04/11/2024] [Indexed: 04/18/2024]
Abstract
p16 is a tumor suppressor encoded by the CDKN2A gene whose expression is lost in approximately 50% of all human cancers. In its canonical role, p16 inhibits the G1-S-phase cell cycle progression through suppression of cyclin-dependent kinases. Interestingly, p16 also has roles in metabolic reprogramming, and we previously published that loss of p16 promotes nucleotide synthesis via the pentose phosphate pathway. However, the broader impact of p16/CDKN2A loss on other nucleotide metabolic pathways and potential therapeutic targets remains unexplored. Using CRISPR knockout libraries in isogenic human and mouse melanoma cell lines, we determined several nucleotide metabolism genes essential for the survival of cells with loss of p16/CDKN2A. Consistently, many of these genes are upregulated in melanoma cells with p16 knockdown or endogenously low CDKN2A expression. We determined that cells with low p16/CDKN2A expression are sensitive to multiple inhibitors of de novo purine synthesis, including antifolates. Finally, tumors with p16 knockdown were more sensitive to the antifolate methotrexate in vivo than control tumors. Together, our data provide evidence to reevaluate the utility of these drugs in patients with p16/CDKN2Alow tumors as loss of p16/CDKN2A may provide a therapeutic window for these agents. SIGNIFICANCE Antimetabolites were the first chemotherapies, yet many have failed in the clinic due to toxicity and poor patient selection. Our data suggest that p16 loss provides a therapeutic window to kill cancer cells with widely-used antifolates with relatively little toxicity.

[PMID: 38194841 PMCID: PMC10843168 DOI: 10.1016/j.msksp.2023.102905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 11/14/2023] [Accepted: 12/26/2023] [Indexed: 01/11/2024]
Abstract
BACKGROUND The OPTimisE intervention was developed to address uncertainty regarding the most effective physiotherapy treatment strategy for people with Lateral Elbow Tendinopathy (LET). OBJECTIVES To assess the feasibility of conducting a fully-powered randomised controlled trial (RCT) evaluating whether the OPTimisE intervention is superior to usual physiotherapy treatment for adults with LET. DESIGN A mixed-methods multi-centred, parallel pilot and feasibility RCT, conducted in three outpatient physiotherapy departments in the UK. METHOD Patients were independently randomised 1:1 in mixed blocks, stratified by site, to the OPTimisE intervention or usual care. Outcomes were assessed using pre-defined feasibility progression criteria. RESULTS 50 patients were randomised (22 Female, 28 Male), mean age 48 years (range 27-75). Consent rate was 71% (50/70), fidelity to intervention 89% (16/18), attendance rate in the OPTimisE group 82% (55/67) vs 85% (56/66) in usual care, outcome measure completion 81% (39/48) at six-month follow-up. There were no related adverse events. Patients and physiotherapists reported that the OPTimisE intervention was acceptable but suggested improvements to the trial design. 49 patients were recruited from physiotherapy referrals vs one from primary care records. Outcome measure return rates were higher when completed online (74%) compared to postal questionnaire (50%). Exploratory analysis showed improvements in both groups over time. CONCLUSIONS It is methodologically feasible to conduct a fully powered RCT comparing the clinical and cost-effectiveness of the OPTimisE intervention versus usual physiotherapy treatment. Considering the similar improvements observed in both groups, careful consideration is needed regarding the priority research question to be addressed in future research.

Abstract
Highly pathogenic avian influenza A H5N1 viruses cause high mortality in humans and have pandemic potential. Effective vaccines and treatments against this threat are urgently needed. Here, we have refined our previously established model of lethal H5N1 infection in cynomolgus macaques. An inhaled aerosol virus dose of 5.1 log10 plaque-forming unit (pfu) induced a strong febrile response and acute respiratory disease, with four out of six macaques succumbing after challenge. Vaccination with three doses of adjuvanted seasonal quadrivalent influenza vaccine elicited low but detectable neutralizing antibody to H5N1. All six vaccinated macaques survived four times the 50% lethal dose of aerosolized H5N1, while four of six unvaccinated controls succumbed to disease. Although vaccination did not protect against severe influenza, vaccinees had reduced respiratory dysfunction and lower viral load in airways compared to controls. We anticipate that our macaque model will play a vital role in evaluating vaccines and antivirals against influenza pandemics.

Abstract
p16 is a tumor suppressor encoded by the CDKN2A gene whose expression is lost in ~50% of all human cancers. In its canonical role, p16 inhibits the G1-S phase cell cycle progression through suppression of cyclin dependent kinases. Interestingly, p16 also has roles in metabolic reprogramming, and we previously published that loss of p16 promotes nucleotide synthesis via the pentose phosphate pathway. Whether other nucleotide metabolic genes and pathways are affected by p16/CDKN2A loss and if these can be specifically targeted in p16/CDKN2A-low tumors has not been previously explored. Using CRISPR KO libraries in multiple isogenic human and mouse melanoma cell lines, we determined that many nucleotide metabolism genes are negatively enriched in p16/CDKN2A knockdown cells compared to controls. Indeed, many of the genes that are required for survival in the context of low p16/CDKN2A expression based on our CRISPR screens are upregulated in p16 knockdown melanoma cells and those with endogenously low CDKN2A expression. We determined that cells with low p16/Cdkn2a expression are sensitive to multiple inhibitors of de novo purine synthesis, including anti-folates. Tumors with p16 knockdown were more sensitive to the anti-folate methotrexate in vivo than control tumors. Together, our data provide evidence to reevaluate the utility of these drugs in patients with p16/CDKN2A-low tumors as loss of p16/CDKN2A may provide a therapeutic window for these agents.

Abstract
OBJECTIVE To synthesise exercise therapy intervention data investigating patient rating outcomes for the management of tendinopathy. DESIGN A systematic review and meta-analysis of randomized controlled trials investigating exercise therapy interventions and reporting patient rating outcomes. SETTING Any setting in any country listed as very high on the human development index. PARTICIPANTS People with a diagnosis of any tendinopathy of any severity or duration. INTERVENTIONS Exercise therapy for the management of tendinopathy comprising five different therapy classes: 1) resistance; 2) plyometric; 3) vibration; 4) flexibility, and 5) movement pattern retraining modalities, were considered for inclusion. MAIN OUTCOME MEASURES Outcomes measuring patient rating of condition, including patient satisfaction and Global Rating of Change (GROC). RESULTS From a total of 124 exercise therapy studies, 34 (Achilles: 41%, rotator cuff: 32%, patellar: 15%, elbow: 9% and gluteal: 3%) provided sufficient information to be meta-analysed. The data were obtained across 48 treatment arms and 1246 participants. The pooled estimate for proportion of satisfaction was 0.63 [95%CrI: 0.53-0.73], and the pooled estimate for percentage of maximum GROC was 53 [95%CrI: 38-69%]. The proportion of patients reporting positive satisfaction and perception of change increased with longer follow-up periods from treatment onset. CONCLUSION Patient satisfaction and GROC appear similar and are ranked moderately high demonstrating that patients generally perceive exercise therapies positively. Further research including greater consistency in measurement tools is required to explore and where possible, identify patient- and exercise-related moderating factors that can be used to improve person-centred care.

Abstract
PURPOSE As drug-related epidemics have expanded from cities to rural areas, syringe service programs (SSPs) and other harm reduction programs have been slow to follow. The recent implementation of SSPs in rural areas demands attention to program fidelity based on core components of SSP success. METHODS Semistructured interviews conducted with clients and staff at 5 SSPs in 5 counties within 2 Central Appalachian health districts. Interviews covered fidelity of SSP implementation to 6 core components: (1) meet needs for harm reduction supplies; (2) education and counseling for sexual, injection, and overdose risks; (3) cooperation between SSPs and local law enforcement; (4) provide other health and social services; (5) ensure low threshold access to services; and (6) promote dignity, the impact of poor fidelity on vulnerability to drug-related harms, and the risk environment's influence on program fidelity. We applied thematic methods to analyze the data. FINDINGS Rural SSPs were mostly faithful to the 6 core components. Deviations from core components can be attributed to certain characteristics of the local rural risk environment outlined in the risk environment model, including geographic remoteness, lack of resources and underdeveloped infrastructure, and stigma against people who inject drugs (PWID) CONCLUSIONS: As drug-related epidemics continue to expand outside cities, scaling up SSPs to serve rural PWID is essential. Future research should explore whether the risk environment features identified also influence SSP fidelity in other rural areas and develop and test strategies to strengthen core components in these vulnerable areas.

Abstract
BACKGROUND Partnering with a public transport (PT) provider, state government, and local government, the single-blinded randomised controlled trial, trips4health, investigated the impact of PT use incentives on transport-related physical activity (PA) in Tasmania, Australia. The intervention involved 16-weeks of incentives (bus trip credits) for achieving weekly PT use targets, supported by weekly text messages. This study objective was to conduct a process evaluation of the COVID-19 disrupted trips4health study. METHODS The Medical Research Council UK's framework for complex public health interventions guided the process evaluation. Participant reach, acceptability, fidelity and feasibility were evaluated. Administrative and post-intervention survey data were analysed descriptively. Semi-structured interviews with intervention participants (n = 7) and PT provider staff (n = 4) were analysed thematically. RESULTS Due to COVID-19, trips4health was placed on hold (March 2020) then stopped (May 2020) as social restrictions impacted PT use. At study cessation, 116 participants (approximately one third of target sample) had completed baseline measures, 110 were randomised, and 64 (n = 29 in the intervention group; n = 35 in the control group) completed post-intervention measures. Participants were 18 - 80 years (average 44.5 years) with females (69%) and those with tertiary education (55%) over-represented. The intervention was delivered with high fidelity with 96% of bus trip credits and 99% of behavioural text messages sent as intended. Interviewed PT staff said implementation was highly feasible. Intervention participant acceptability was high with 90% reporting bus trip incentives were helpful and 59% reporting the incentives motivated them to use PT more. From a total of 666 possible bus trip targets, 56% were met with 38% of intervention participants agreeing and 41% disagreeing that 'Meeting the bus trip targets was easy'. Interviews and open-ended survey responses from intervention participants revealed incentives motivated bus use but social (e.g., household member commitments) and systemic (e.g., bus availability) factors made meeting bus trip targets challenging. CONCLUSIONS trips4health demonstrated good acceptability and strong fidelity and feasibility. Future intervention studies incentivising PT use will need to ensure a broader demographic is reached and include more supports to meet PT targets. TRIAL REGISTRATION ACTRN12619001136190 .

Abstract
BACKGROUND Physiotherapy is recommended for people with tennis elbow, but whilst a wide array of treatments is available, the optimal approach remains uncertain. We have therefore recently developed an optimised physiotherapy treatment package for tennis elbow based on a synthesis of the evidence, patient input and clinical consensus. It consists of detailed advice and education, a structured progressive exercise programme and provision of a counter-force elbow brace. Here, we report the protocol for our multicentre pilot and feasibility randomised controlled trial (RCT) designed to (a) examine the feasibility of our optimised physiotherapy treatment package and (b) to pilot trial processes for a future fully powered RCT to test clinical and cost-effectiveness compared with usual physiotherapy treatment. METHODS A multicentre pilot and feasibility RCT will be conducted across three sites in England, recruiting up to 50 patients (or for a maximum of 12 months). Participants with tennis elbow, identified from physiotherapy clinic waiting lists and general practice surgeries, will be randomly allocated to receive the optimised physiotherapy treatment package or usual physiotherapy care. Analysis will focus on feasibility measures including consent rate, intervention fidelity, follow-up rate and outcome completion rate. A nested qualitative study will explore the acceptability of the study processes and patient and physiotherapist experiences of the new optimised intervention. DISCUSSION This study will determine the feasibility of a new optimised physiotherapy treatment package for people with tennis elbow and pilot the processes for a future fully powered RCT. In the longer term, this treatment package may provide superior clinical outcomes for patients, in terms of pain and quality of life, and be more cost-effective for the health service.

Abstract
Health-related fear is a normal and common response in the face of the global pandemic of COVID-19. Children and young people are frequently being exposed to messages about the threat to health, including from the media and authorities. Whilst for most, their anxiety will be proportionate to the threat, for some, existing pre-occupation with physical symptoms and illness will become more problematic. There is a growing body of evidence that health anxiety may occur in childhood, however much of the literature is taken from research using adult samples. This practitioner review aims to give an overview of the assessment and treatment of health-related worries in children and young people in the context of the COVID-19 pandemic. This review is based on the limited existing evidence in this population and the more substantial evidence base for treating health anxiety in adults. We consider the adaptations needed to ensure such interventions are developmentally appropriate.

Abstract
PURPOSE Patients treated with cytotoxic chemotherapy are at risk of neutropenia, neutropenic fever and neutropenic sepsis. We hypothesised that pre-existing neutrophil function dysfunction may increase susceptibility to neutropenic fever in paediatric patients receiving cytotoxic chemotherapy. METHODS Prospective cohort study recruited patients at Alder Hey Children's NHS Foundation Trust, United Kingdom. We measured neutrophil phagocytic function using a validated flow cytometric whole blood phagocytosis assay in paediatric patients (n = 16) with oncological disease before and after chemotherapy in a prospective cohort study. We recruited healthy children as a control comparator (n = 10). RESULTS We found significantly decreased phagocytic function in oncology patients compared to healthy participants. In five patients who developed neutropenic fever, we observed increased pre-dose neutrophil respiratory burst. CONCLUSION With further validation, measurement of neutrophil function could potentially be used to personalise appropriate prophylactic antimicrobial administration for patients receiving cytotoxic chemotherapy.

Comparability of blinded remote and site-based assessments of response to adjunctive esketamine or placebo nasal spray in patients with treatment resistant depression. J Psychiatr Res 2019; 111:68-73. [PMID: 30685564 DOI: 10.1016/j.jpsychires.2019.01.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2018] [Revised: 12/18/2018] [Accepted: 01/18/2019] [Indexed: 11/26/2022]
Abstract
Functional unblinding due to treatment emergent adverse events (TEAEs) may occur with any investigational drug and poses a challenge for double-blind, placebo-controlled studies. This pilot study compared site-based Montgomery-Asberg Depression Rating Scale (MADRS) scores to remote, site-independent scores by blinded raters. Audio-digital recordings of site-based MADRS interviews were obtained from a subset of patients during a double-blind, placebo-controlled study of esketamine nasal spray or placebo spray in treatment resistant depression (Clinical Trials Registration: NCT01998958). Fourteen of 67 patients (21%) in the ITT population were randomly selected from 3 clinical trial sites. The site-based MADRS interviews were recorded at the baseline and 2 h post-dose assessments on the first intranasal dosing day. Site-independent raters scored the recordings and were blinded to treatment and all reported TEAEs, including any transient dissociative/perceptual symptoms. None of the 7 placebo-assigned patients achieved a treatment response or remission at the 2-h post-dose assessment. Four of the 7 esketamine-assigned patients (57.1%) achieved a treatment response at 2-h post-dose, and 3 patients (42.9%) achieved remission. Three esketamine-treated patients experienced transient dissociative symptoms. The remote site-independent raters essentially replicated the site-based MADRS scores and yielded a 92.9% predictive value for matching treatment response and remission rates. This small pilot study affirms that blinded remote ratings (without the likelihood of functional unblinding) are comparable to site-based ratings of efficacy of esketamine nasal spray. The audio-digital recording method offers a reasonable strategy for other studies that may also be vulnerable to functional unblinding due to distinctive TEAEs.

Abstract
Background: High-quality data can assist the development of policy and cancer strategies, stimulate lines of research, and inform the provision of care leading to better cancer outcomes. In November 2017 Cancer Australia launched the National Cancer Control Indicators (NCCI) Web site ( https://ncci.canceraustralia.gov.au ), Australia's first interactive Web site of cancer-specific, national population-based data across the continuum of care. The NCCI Web site presents a set of indicators for monitoring national cancer trends and benchmarking internationally across seven key aspects of cancer control; prevention, screening, diagnosis, treatment, psychosocial care, research and outcomes. Aim: By presenting a set of indicators using seven domains from the cancer care continuum, the NCCI Web site presents the most current Australian national data for a range of cancer control indicators in an accessible and interactive format. The primary aim of the NCCI Web site (hosted as part of the Cancer Australia Web site) is to monitor and report the most recent population-level trends to drive improvements across the cancer control continuum in Australia, and to facilitate international benchmarking of Australia's cancer control efforts. Methods: National data level on 33 individual measures across the seven cancer continuum domains was accessed from both government and nongovernment data custodians. Where applicable and available for measures, data were disaggregated and presented by age, sex, indigenous status, remoteness area of residence and socioeconomic status. Review of the data analysis was undertaken by 46 external reviewers including data custodians and subject matter experts. Results: Example summary data from several indicators across the NCCI Web site, including demographic disaggregation by age, sex, remoteness area of residence and socioeconomic status (where available) will be provided. e.g., • Smoking prevalence has decreased substantially over the past 30 years, and smoking rates among both adolescents and adults in Australia are among the lowest in the world. • Cancer mortality rates have been falling steadily since 1995, across most cancer types. Australia has lower mortality rates from cancer when compared with most other similar developed countries, about 6% lower than the estimated global average in 2012. National population-level data showing incidence by stage at diagnosis for the top five most common cancers has also been reported on the Web site - making Australia one of the few countries in the world where these data are available. Conclusion: The NCCI Web site is a flagship data Web site providing, for the first time, an evolving high-level national data resource to monitor Australian population-level trends in cancer control across the continuum. As one of the very few cross-continuum cancer reporting resources in the world, this is a valuable resource for use by those within the international cancer control community.

Abstract
Worldwide prevalence of adult overweight and obesity is a growing public health issue. Adults with overweight/obesity often have chronic musculoskeletal pain. Using a mixed-methods review, we aimed to quantify the effectiveness and explore the appropriateness of weight loss interventions for this population. Electronic databases were searched for studies published between 01/01/90 and 01/07/16. The review included 14 randomized controlled trials that reported weight and pain outcomes and three qualitative studies that explored perceptions of adults with co-existing overweight/obesity and chronic musculoskeletal pain. The random-effects pooled mean weight loss was 4.9 kg (95%CI:2.9,6.8) greater for intervention vs control. The pooled mean reduction in pain was 7.3/100 units (95%CI:4.1,10.5) greater for intervention vs control. Study heterogeneity was substantial for weight loss (I2 = 95%, tau = ±3.5 kg) and pain change (I2 = 67%, tau = ±4.1%). Meta-regression slopes for the predictors of study quality, mean age and baseline mean weight on mean study weight reduction were shallow and not statistically significant (P > 0.05). The meta-regression slope between mean pain reduction and mean weight lost was shallow, and not statistically significant, -0.09 kg per unit pain score change (95%CI:-0.21,0.40, P = 0.54). Meta-synthesis of qualitative findings resulted in two synthesized findings; the importance of healthcare professionals understanding the effects of pain on ability to control weight and developing management/education programmes that address comorbidity.

Abstract
BACKGROUND Psychological interventions informed by cognitive behavioural theory have proven efficacy in treating mild-moderate anxiety and depression. They have been successfully adapted for autistic children and adults who experience disproportionately high rates of co-occurring emotional problems. There has been little research into the perspectives and experience of psychological therapists adapting cognitive behavioural therapy (CBT) as part of routine clinical practice. We surveyed therapist skills, experience and confidence in working psychologically with autistic people, in order to highlight gaps and needs, as well as strengths in terms of therapist skills when working with this group. METHOD Fifty therapists attending a training event completed a survey about their experience of adapting CBT for autistic clients, alongside a measure of therapist confidence. RESULTS Almost all therapists reported making adaptations to CBT practice when working with autistic clients. Key challenges identified were rigidity in thinking and pacing sessions appropriately. Therapists were relatively confident about core engagement and assessment skills but reported less confidence in using their knowledge to help this group. Therapist confidence was not associated with years of practice or number of adaptations made, but was positively associated with level of therapy training received. CONCLUSIONS This study highlights a need for training and ongoing supervision to increase therapist confidence in and ability to make appropriate adaptations to CBT treatment protocols for autistic people.

The effect of pitched and vertical ladder ergometer climbing on cardiorespiratory and psychophysical variables. APPLIED ERGONOMICS 2018; 66:172-176.

Abstract
This study aimed to assess whether modifying the pitch of a 75° ladder ergometer to vertical had a cardiorespiratory or psychophysical effect on climbing. Nine male participants climbed a ladder ergometer at 75° and subsequently at 90°, adjusted for an equivalent vertical climb rate, completing three climbing bouts at different vertical speeds. One participant dropped out being unable to complete the climb under the 90° condition. Each was monitored for heart rate (HR), V˙O2 and rating of perceived exertion (RPE). Results showed vertical climbing induced higher V˙O2 (mean increase 17.3%), higher HR (mean increase 15.8%), and higher RPE at all speeds and that moving from 75°to vertical exacerbates the effect of speed on the cardiorespiratory response to climbing. This may be explained by increased force production required to maintain balance in a vertical climbing position when the body's centre of mass is not above the feet.
