Cancer incidence, treatment, and survival in the prison population compared with the general population in England: a population-based, matched cohort study.

BACKGROUND: The growing and ageing prison population in England makes accurate cancer data of increasing importance for prison health policies. This study aimed to compare cancer incidence, treatment, and survival between patients diagnosed in prison and the general population. METHODS: In this population-based, matched cohort study, we used cancer registration data from the National Cancer Registration and Analysis Service in England to identify primary invasive cancers and cervical cancers in situ diagnosed in adults (aged ≥18 years) in the prison and general populations between Jan 1, 1998, and Dec 31, 2017. Ministry of Justice and Office for National Statistics population data for England were used to calculate age-standardised incidence rates (ASIR) per year and age-standardised incidence rate ratios (ASIRR) for the 20-year period. Patients diagnosed with primary invasive cancers (ie, excluding cervical cancers in situ) in prison between Jan 1, 2012, and Dec 31, 2017 were matched to individuals from the general population and linked to hospital and treatment datasets. Matching was done in a 1:5 ratio according to 5-year age group, gender, diagnosis year, cancer site, and disease stage. Our primary objectives were to compare the incidence of cancer (1998-2017); the receipt of treatment with curative intent (2012-17 matched cohort), using logistic regression adjusted for matching variables (excluding cancer site) and route to diagnosis; and overall survival following cancer diagnosis (2012-17 matched cohort), using a Cox proportional hazards model adjusted for matching variables (excluding cancer site) and route to diagnosis, with stratification for the receipt of any treatment with curative intent. FINDINGS: We identified 2015 incident cancers among 1964 adults (1556 [77·2%] men and 459 [22·8%] women) in English prisons in the 20-year period up to Dec 31, 2017. The ASIR for cancer for men in prison was initially lower than for men in the general population (in 1998, ASIR 119·33 per 100 000 person-years [95% CI 48·59-219·16] vs 746·97 per 100 000 person-years [742·31-751·66]), but increased to a similar level towards the end of the study period (in 2017, 856·85 per 100 000 person-years [675·12-1060·44] vs 788·59 per 100 000 person-years [784·62-792·57]). For women, the invasive cancer incidence rate was low and so ASIR was not reported for this group. Over the 20-year period, the incidence of invasive cancer for men in prison increased (incidence rate ratio per year, 1·05 [95% CI 1·04-1·06], during 1999-2017 compared with 1998). ASIRRs showed that over the 20-year period, overall cancer incidence was lower in men in prison than in men in the general population (ASIRR 0·76 [95% CI 0·73-0·80]). The difference was not statistically significant for women (ASIRR 0·83 [0·68-1·00]). Between Jan 1, 2012, and Dec 31, 2017, patients diagnosed in prison were less likely to undergo curative treatment than matched patients in the general population (274 [32·3%] of 847 patients vs 1728 [41·5%] of 4165; adjusted odds ratio (OR) 0·72 [95% CI 0·60-0·85]). Being diagnosed in prison was associated with a significantly increased risk of death on adjustment for matching variables (347 deaths during 2021·9 person-years in the prison cohort vs 1626 deaths during 10 944·2 person-years in the general population; adjusted HR 1·16 [95% CI 1·03-1·30]); this association was partly explained by stratification by curative treatment and further adjustment for diagnosis route (adjusted HR 1·05 [0·93-1·18]). INTERPRETATION: Cancer incidence increased in people in prisons in England between 1998 and 2017, with patients in prison less likely to receive curative treatments and having lower overall survival than the general population. The association with survival was partly explained by accounting for differences in receipt of curative treatment and adjustment for diagnosis route. Improved routine cancer surveillance is needed to inform prison cancer policies and decrease inequalities for this under-researched population.

Prospective manipulation of the gut microbiome with microbial ecosystem therapeutic 4 (MET4) in HPV-related locoregionally-advanced oropharyngeal cancer squamous cell carcinoma (LA-OPSCC) undergoing primary chemoradiation: ROMA2 study.

BACKGROUND: Gut microbiome modulation to boost antitumor immune responses is under investigation. METHODS: ROMA-2 evaluated the microbial ecosystem therapeutic (MET)-4 oral consortia, a mixture of cultured human stool-derived immune-responsiveness associated bacteria, given with chemoradiation (CRT) in HPV-related oropharyngeal cancer patients. Co-primary endpoints were safety and changes in stool cumulative MET-4 taxa relative abundance (RA) by 16SRNA sequencing. Stools and plasma were collected pre/post-MET-4 intervention for microbiome and metabolome analysis. RESULTS: Twenty-nine patients received ≥1 dose of MET-4 and were evaluable for safety: drug-related adverse events (AEs) occurred in 13/29 patients: all grade 1-2 except one grade 3 (diarrhea). MET-4 was discontinued early in 7/29 patients due to CRT-induced toxicity, and in 1/29 due to MET-4 AEs. Twenty patients were evaluable for ecological endpoints: there was no increase in stool MET-4 RA post-intervention but trended to increase in stage III patients (p = 0.06). MET-4 RA was higher in stage III vs I-II patients at week 4 (p = 0.03) and 2-month follow-up (p = 0.01), which correlated with changes in plasma and stool targeted metabolomics. CONCLUSIONS: ROMA-2 did not meet its primary ecologic endpoint, as no engraftment was observed in the overall cohort. Exploratory findings of engraftment in stage III patients warrants further investigation of microbiome interventions in this subgroup.

Is there scope to do better? Clinical communication with adolescents and young adults with cancer-A scoping review.

INTRODUCTION: How to communicate effectively with adolescent and young adults with cancer (AYACs) is a research priority. In a UK-wide survey of young people with cancer's research priorities, communication was a striking cross-cutting theme. It is increasingly recognised that AYACs have experiences and communication needs that differ significantly from those of younger children and older adults. The purpose of this review is to explore the features of effective clinical communication with AYACs. METHODS: A literature search was undertaken to identify and map the available evidence using a broad scope to get an overview of the pertinent literature, identify knowledge gaps and clarify concepts. The searches yielded 5825 records, generating 4040 unique articles. These were screened and 71 full articles were read by four researchers with disagreements resolved by discussion leaving 29 included articles. Narrative synthesis was undertaken in relation to each of the research questions. RESULTS: Three key themes were identified: being an adolescent/young adult, supporters, and healthcare professionals (HCPs). AYACs need to feel that HCPs understand their unique perspective. They want to be involved, this changes over time and in different contexts. Supporters are a central tenet, are most often parents and undertake several roles which are not always universally supportive. HCPs enable involvement of AYACs, and this needs to be actively promoted. AYACs preference for their level of involvement requires continual assessment. The three themes are interlinked and exist within the wider scope of the triadic encounter and cancer experience. CONCLUSION: Supporters, most often parents were a key feature across the data and were seemingly paradoxical in nature. Triadic communication, the presence of a third person, is a central tenet of communication with AYACs and we propose a conceptual model to represent the nuances, components, and facets of this complex communication.

Psychosocial and Support Needs of the Main Caregiver for Adolescents and Young Adults Undergoing Treatment for Cancer.

BACKGROUND: Family relationships and social networks are critically important to adolescents and young adults (AYAs) with cancer, impacting their experience and well-being throughout the cancer trajectory. A cancer diagnosis impacts the development of independence and an adult identity, which can present challenges to psychosocial well-being needs and relationships between caregivers and AYAs. OBJECTIVE: The aim of this study was to explore the psychosocial and support needs of the main caregivers of AYAs. METHODS: This is a secondary analysis of the BRIGHTLIGHT caregiver survey, exploring items pertaining to support offered/engaged with, appraisal of helpfulness, and caregivers' emotional and psychological distress experience. Descriptive statistics, a correlational analysis, and a 1-way analysis of variance were conducted. RESULTS: There were 518 caregiver responses (62%). Over half received information about their caregiving needs, with the majority finding this very/fairly helpful. Most (80%) of those who had not received the information would have valued it. High levels of negative emotional and psychological well-being were reported, with 91% feeling depressed or anxious since the AYAs' diagnosis and 41% always/often experiencing these feelings. Total distress was associated with being younger, a parent, female, and unemployed, and earning a below-average income. CONCLUSIONS: The needs of caregivers are broad and multidimensional; however, some characteristics were associated with higher distress. When caregiver-specific information was provided by healthcare professionals, it was well received. IMPLICATIONS FOR PRACTICE: Healthcare professionals should consider caregivers' needs individually and provide/signpost to support. Caregivers need to be involved in designing and implementing future research, given the heterogeneity of needs identified.

The Emotional Impact of a Cancer Diagnosis: A Qualitative Study of Adolescent and Young Adult Experience.

The biographical disruption that occurs in adolescents and young adults following a cancer diagnosis can affect various important psychosocial domains including relationships with family and friends, sexual development, vocational and educational trajectories, and physical and emotional wellbeing. While there is evidence of the physical impact of cancer during this period, less is known about the impact on emotional wellbeing and especially on the barriers for young people accessing help and support. We aimed to obtain a more in-depth understanding of young people's experiences of their diagnosis, treatment, psychological impact, and range of resources they could or wanted to access for their mental health. We conducted an in-depth qualitative study using semi-structured interviews with 43 young people who had developed cancer aged 16 to 39 years and were either within 6 months of diagnosis or 3-5 years after treatment had ended. Framework analysis identified three themes: the emotional impact of cancer (expressed through anxiety, anger, and fear of recurrence); personal barriers to support through avoidance; and support to improve mental health through mental health services or adolescent and young adult treatment teams. We showed the barriers young people have to access care, particularly participant avoidance of support. Interrupting this process to better support young people and provide them with flexible, adaptable, consistent, long-term psychological support has the potential to improve their quality of life and wellbeing.

The Sarcoma Assessment Measure (SAM): Preliminary Psychometric Validation of a Novel Patient-Reported Outcome Measure.

The Sarcoma Assessment Measure (SAM) was developed as a sarcoma-specific patient-reported outcome measure to be used in clinical practice. We have reported in detail how SAM has been developed in collaboration with patients and healthcare professionals. The aim of this paper is to report the preliminary validation of SAM. The 22-item SAM was administered alongside a validated quality of life questionnaire and measure of activities of daily living. Linear modelling was used to build a measure, which had predictive validity in comparison to more established outcome measures. Of the 762 patients who participated in the study, 44.1% identified as male, and participant age ranged from 13 to 82 years. Clinically, participants presented with a range of soft tissue (82.2%) and bone (21.8%) sarcomas. Our preliminary analysis indicates that SAM accounts for 35% of the global quality of life scale and 18% of the Toronto Extremity Salvage Scale (TESS); so psychometrically, it overlaps with quality of life and activities of daily living, but also measures distinct concerns. This demonstrates that this measure picks up issues that are important to patients with sarcoma that are not reflected in other measures. We have established the preliminary validity of SAM and believe it has utility as a patient-reported outcome measure both as a research tool and for assessing the impact of symptoms and dysfunction related to sarcoma as part of clinical care. Further validation using a larger and more clinically diverse sample is now needed.

Triadic communication with teenagers and young adults with cancer: a systematic literature review - 'make me feel like I'm not the third person'.

OBJECTIVES: Clinical communication needs of teenagers and young adults with cancer (TYACs) are increasingly recognised to differ significantly from younger children and older adults. We sought to understand who is present with TYACs, TYACs' experiences of triadic communication and its impact. We generated three research questions to focus this review: (1) Who is present with TYACs in healthcare consultations/communication?, (2) What are TYACs' experiences of communication with the supporter present? and (3) What is the impact of a TYAC's supporter being present in the communication? DESIGN: Systematic review with narrative synthesis. DATA SOURCES: The search was conducted across six databases: Medline, CINAHL, Embase, PsycINFO, Web of Science and AMED for all publications up to December 2023. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Included papers were empirical research published after 2005; participants had malignant disease, diagnosed aged 13-24 years (for over 50% of participants); the research addressed any area of clinical communication. DATA EXTRACTION AND SYNTHESIS: Three independent reviewers undertook full-text screening. A review-specific data extraction form was used to record participant characteristics and methods from each included paper and results relevant to the three review questions. RESULTS: A total of 8480 studies were identified in the search, of which 36 fulfilled the inclusion criteria. We found that mothers were the most common supporter present in clinical communication encounters. TYACs' experiences of triadic communication are paradoxical in nature-the supporter can help or hinder the involvement of the young person in care-related communication. Overall, young people are not included in clinical communication and decisions at their preferred level. CONCLUSION: Triadic communication in TYACs' care is common, complex and dynamic. Due to the degree of challenge and nuances raised, healthcare professionals need further training on effective triadic communication. PROSPERO REGISTRATION NUMBER: CRD42022374528.

The Impact of Specialist Care on Teenage and Young Adult Patient-Reported Outcomes in England: A BRIGHTLIGHT Study.

Purpose: In England, health care policy promotes specialized age-appropriate cancer services for teenagers and young adults (TYA), for those aged 13-24 years at diagnosis. Specialist Principal Treatment Centers (PTCs) provide enhanced age-specific care for TYA, although many still receive all or some of their care in adult or children's cancer services. Our aim was to determine the patient-reported outcomes associated with TYA-PTC based care. Methods: We conducted a multicenter cohort study, recruiting 1114 TYA aged 13-24 years at diagnosis. Data collection involved a bespoke survey at 6,12,18, 24, and 36 months after diagnosis. Confounder adjusted analyses of perceived social support, illness perception, anxiety and depression, and health status, compared patients receiving NO-TYA-PTC care with those receiving ALL-TYA-PTC and SOME-TYA-PTC care. Results: Eight hundred and thirty completed the first survey. There was no difference in perceived social support, anxiety, or depression between the three categories of care. Significantly higher illness perception was observed in the ALL-TYA-PTC and SOME-TYA-PTC group compared to the NO-TYA-PTC group, (adjusted difference in mean (ADM) score on Brief Illness Perception scale 2.28 (95% confidence intervals [CI] 0.48-4.09) and 2.93 [1.27-4.59], respectively, p = 0.002). Similarly, health status was significantly better in the NO-TYA-PTC (ALL-TYA-PTC: ADM -0.011 [95%CI -0.046 to 0.024] and SOME-TYA-PTC: -0.054 [-0.086 to -0.023]; p = 0.006). Conclusion: The reason for the difference in perceived health status is unclear. TYA who accessed a TYA-PTC (all or some care) had higher perceived illness. This may reflect greater education and promotion of self-care by health care professionals in TYA units.

Choosing the right questions - A systematic review of patient reported outcome measures used in radiotherapy and proton beam therapy.

The implementation of PROMs into clinical practice has been shown to improve quality of care. This systematic review aims to identify which PROMs are suitable for implementation within routine clinical practice in a radiotherapy or PBT service.The bibliographic databases MEDLINE, EMBASE and EMCARE were searched. Articles published between 1st January 2008 to 1st June 2023, that reported PROMs being utilised as an outcome measure were included. Inclusion criteria also included being written in English, involving human patients, aged 16 and above, receiving external beam radiotherapy or PBT for six defined tumour sites. PROMs identified within the included articles were subjected to quality assessment using the COSMIN reporting guidelines. Results are reported as per PRISMA guidelines. A total of 268 studies were identified in the search, of which 52 fulfilled the inclusion criteria. The use of 39 different PROMs was reported. The PROMs identified were mostly tumour or site-specific quality of life (n = 23) measures but also included generic cancer (n = 3), health-related quality-of-life (n = 6), and symptom specific (n = 7) measures.None of the PROMs identified received a high GRADE score for good content. There were 13 PROMs that received a moderate GRADE score. The remaining PROMs either had limited evidence of development and validation within the patient cohorts investigated, or lacked relevance or comprehensiveness needed for routine PROMs collection in a radiotherapy or PBT service.This review highlights that there are a wide variety of PROMs being utilised within radiotherapy research, but most lack specificity to radiotherapy side-effects. There is a risk that by using non-specific PROMs in clinical practice, patients might not receive the supportive care that they need.

Young people's opinions of cancer care in England: the BRIGHTLIGHT cohort.

OBJECTIVES: The BRIGHTLIGHT cohort study was the national evaluation of cancer services for teenager and young adults (TYA). This was analysis of free-text survey data to better understand their experiences of cancer care. DESIGN: Cohort study SETTING: National Health Service hospitals delivering cancer care in England PARTICIPANTS: 830 young people newly diagnosed with cancer. INTERVENTIONS: Exposure to specialist care in the first 6 months after diagnosis defined as care in a TYA Principal Treatment Centre (PTC). This was categorised as follows: all care in a TYA-PTC (ALL-TYA-PTC), no care in a TYA-PTC (NO-TYA-PTC) so care delivered in a children/adult unit only and some care in a TYA-PTC with additional care in a children's/adult unit (SOME-TYA-PTC). PRIMARY OUTCOME: Data were collected through the BRIGHTLIGHT survey included free-text questions which asked patients 'what was the best aspects of their experiences of care' and 'what aspects could be improved'. These comments were analysed using content analysis. Themes were compared between categories of care, then ranked in order of frequency, ranging from the most endorsed to the least. RESULTS: Overall, young people were most positive about their healthcare team, while the area highlighted for improvement was diagnostic experience. Differences between the three groups suggested those who had some or all treatment in a TYA-PTC valued the place of care. Regardless of where TYA were treated their healthcare teams were favourably viewed. Age appropriate place of care was highlighted to be of value for those in PTCs. CONCLUSIONS: These data show the value young people placed on the care they received in TYA specific wards. Young people who accessed some or all of their care in a TYA-PTC highly endorsed their place of care as one of the best elements of their care, and it is further emphasised by those who had shared care who experienced difficulty with lack of age-appropriate care when treated outside the TYA-PTC.

Patients' Experiences of a Sarcoma Diagnosis: A Process Mapping Exercise of Diagnostic Pathways.

Patients with sarcoma often report prolonged time to diagnosis, which is attributed to the rarity of sarcoma and the low awareness of pre-diagnostic signs and symptoms. AIMS: To describe patients' experiences of pre-diagnostic signs/symptoms and pathways to diagnosis, including where help was sought, and the processes involved. METHODS: Mixed methods involving quantitative, qualitative and inductive thematic analyses using novel process mapping of patient journey data, as reported by the patients. We examined the time from symptom onset to first professional presentation (patient interval, PI), first consultation to diagnostic biopsy, first consultation to diagnosis (diagnostic interval) and first presentation to diagnosis (total interval). RESULTS: A total of 87 interviews were conducted over 5 months in 2017. Of these, 78 (40 males/38 females) were included. The sarcoma subtypes were bone (n = 21), soft tissue (n = 41), head and neck (n = 9) and gastro-intestinal (GIST; n = 7). Age at diagnosis was 13-24 (n = 7), 25-39 (n = 23), 40-64 (n = 34) and 65+ (n = 14) years. The median PI was 13 days (1-4971) and similar between sarcoma subtypes, with the exception of GIST (mPI = 2 days, (1-60). The longest mPI (31 days, range 4-762) was for those aged 13-24 years. The median diagnostic interval was 87.5 (range 0-5474 days). A total of 21 patients were misdiagnosed prior to diagnosis and symptoms were commonly attributed to lifestyle factors. CONCLUSIONS: Prolonged times to diagnosis were experienced by the majority of patients in our sample. Further research into the evolution of pre-diagnostic sarcoma symptoms is required to inform awareness interventions.

Fear of Cancer Recurrence in Patients with Sarcoma in the United Kingdom.

Fear of cancer recurrence (FCR) is a persistent concern among those living with cancer and is associated with a variety of negative psychosocial outcomes. However, people with sarcoma have been underrepresented within this area of research. We aimed to determine the prevalence of FCR experienced by people with sarcoma in the United Kingdom and explore factors that may predict FCR, such as the perceived impact of cancer and psychological flexibility. Participants (n = 229) with soft tissue (n = 167), bone (n = 25), and gastrointestinal stromal tumours (n = 33) completed an online survey including the self-reported measures of FCR, the perceived physical and psychological impact of cancer and psychological flexibility, and demographic information. Data were analysed using ANOVA and multiple regression modelling. Mean FCR scores (M = 91.4; SD = 26.5) were higher than those reported in meta-analytic data inclusive of all cancer types (M = 65.2; SD = 28.2). Interest in receiving support for FCR was also high (70%). Significant factors associated with FCR included cognitive and emotional distress and psychological flexibility, but not perceptions of the physical impact of cancer (R2 = 0.56). The negative association between psychological flexibility and FCR suggests the potential benefit of intervention approaches which foster psychological flexibility, such as acceptance and commitment therapy.

In Vivo Longitudinal Monitoring of Cardiac Remodeling in Murine Ischemia Models With Adaptive Bayesian Regularized Cardiac Strain Imaging: Validation Against Histology.

Adaptive Bayesian regularized cardiac strain imaging (ABR-CSI) uses raw radiofrequency signals to estimate myocardial wall contractility as a surrogate measure of relative tissue elasticity incorporating regularization in the Bayesian sense. We determined the feasibility of using ABR-CSI -derived strain for in vivo longitudinal monitoring of cardiac remodeling in a murine ischemic injury model (myocardial infarction [MI] and ischemia-reperfusion [IR]) and validated the findings against ground truth histology. We randomly stratified 30 BALB/CJ mice (17 females, 13 males, median age = 10 wk) into three surgical groups (MI = 10, IR = 12, sham = 8) and imaged pre-surgery (baseline) and 1, 2, 7 and 14 d post-surgery using a pre-clinical high-frequency ultrasound system (VisualSonics Vevo 2100). We then used ABR-CSI to estimate end-systolic and peak radial (er) and longitudinal (el) strain estimates. ABR-CSI was found to have the ability to serially monitor non-uniform cardiac remodeling associated with murine MI and IR non-invasively through temporal variation of strain estimates post-surgery. Furthermore, radial end-systole (ES) strain images and segmental strain curves exhibited improved discrimination among infarct, border and remote regions around the myocardium compared with longitudinal strain results. For example, the MI group had significantly lower (Friedman's with Bonferroni-Dunn test, p = 0.002) ES er values in the anterior middle (infarcted) region at day 14 (n = 9, 9.23 ± 7.39%) compared with the BL group (n = 9, 44.32 ± 5.49). In contrast, anterior basal (remote region) mean ES er values did not differ significantly (non-significant Friedman's test, χ2 = 8.93, p = 0.06) at day 14 (n = 6, 33.05 ± 6.99%) compared with baseline (n = 6, 34.02 ± 6.75%). Histology slides stained with Masson's trichrome (MT) together with a machine learning model (random forest classifier) were used to derive the ground truth cardiac fibrosis parameter termed histology percentage of myocardial fibrosis (PMF). Both radial and longitudinal strain were found to have strong statistically significant correlations with the PMF parameter. However, radial strain had a higher Spearman's correlation value (εresρ = -0.67, n = 172, p < 0.001) compared with longitudinal strain (εlesρ = -0.60, n = 172, p < 0.001). Overall, the results of this study indicate that ABR-CSI can reliably perform non-invasive detection of infarcted and remote myocardium in small animal studies.

A Qualitative Study of the Factors Influencing Patients' Experience of Soft Tissue Sarcoma in the United Kingdom.

BACKGROUND: Treatment of soft tissue sarcoma frequently involves extensive surgery, loss of mobility, and complex rehabilitation programs. Poorer patient-reported outcomes are reported in comparison to those from patients with other cancer types. Understanding patient experience is therefore important to support patients and improve care. OBJECTIVE: The aim of this study was an in-depth exploration of patients' experience of being diagnosed with soft tissue sarcoma. METHODS: Semistructured interviews and focus groups were conducted with 68 patients with soft tissue sarcoma (59% female; aged 23-82 years). These were analyzed using adapted framework analysis. RESULTS: Two overarching themes explained the factors influencing patients' experiences: individual and social factors to manage the impact of soft tissue sarcoma; and context and processes of care. Access to professionals with sarcoma expertise and services in specialist hospitals had an impact on patients' well-being. Lack of access to specialist services and coordinated care were associated with worse experiences. These were influenced by age and support from family/friends/other patients and were crucial in patients' adaptation to living with and beyond a sarcoma diagnosis. CONCLUSION: We describe factors that both negatively and positively influenced the experience of patients with soft tissue sarcoma. Access to specialist soft tissue sarcoma and rehabilitation services and support tailored to patients' age and disease trajectory are needed to improve these experiences. IMPLICATION FOR PRACTICE: Nurses are important for helping patients manage the long-term effects and directing them to supportive care services. Rehabilitation services need to be available and easily accessible.

Interventions to prevent hypothermia in extremely preterm low-weight infants undergoing cardiac catheterisation.

BACKGROUND: In January 2019, a new device called the Amplatzer Piccolo Occluder was approved by the US Food and Drug Administration for percutaneous closure of patent ductus arteriosus in infants weighing more than 700 g and of postnatal age more than 3 days. Premature low-weight infants are predisposed to hypothermia when transported outside of the thermo-neutral environment. At our institution, 90% of extremely preterm low-weight infants developed transient moderate hypothermia in the cardiac catheterisation suite. METHODS: We conducted a study testing multiple hypotheses aimed at preventing hypothermia in the cardiac catheterisation suite. Interventions included increasing ambient room temperature, reducing exposure to cold environment and reducing overall time spent in the remote location. The primary outcome was the proportion of patients who developed transient hypothermia at the start of the procedure in the cardiac catheterisation suite. The secondary measures included mean core body temperature at four different instances, as well as anaesthesia time, procedure time and radiation exposure. RESULTS: During the study period, 10 patients were enrolled in each group. The postintervention group saw a reduction in transient hypothermia from 90% to 40% (absolute risk reduction 50%, p=0.02). Data analysis showed an improvement in mean core body temperature (35.4°C vs 36.4°C, p<0.01) as well as a smaller percentage drop in temperature (4% vs 1.3%, p<0.01) between the two groups, both of which were statistically significant. The anaesthesia time, procedure time and radiation exposure reduced between the two groups. CONCLUSION: The application of the interventions reduced hypothermia in this high-risk population. The implementation of a protocol with collaboration of a multidisciplinary team is indispensable in providing optimal care to extremely preterm infants.

Care coordination, consistency and continuity: the case of the key worker role in children's cancer care.

PURPOSE: The overall aim was to evaluate the key worker role across principal treatment centres for children with cancer in England, Wales and Scotland. METHODS: Mixed-methods case study gathering data from multiple perspectives using questionnaires, interviews, focus groups and reports/performance documents over a two-year period. Framework approach was adopted to analyse transcripts and documentary data. RESULTS: Participants included: 22 nurse specialist key workers, 103 parents, 85 professionals and 10 children/young people. Qualitative and quantitative data were woven together, to best illuminate key worker services. Four main models of care were described as well as the context of care and process of care. Key working effectiveness centred around three pillars: care coordination; expert knowledge, experience and expertise; relationship. These were essential to improved family experience, emotional wellbeing, and delivery of individualized care closer to home. CONCLUSIONS: The role is complex and diverse, responding to local needs. Certain conditions, (e.g., high caseload) placed limits on enacting the three pillars, diminishing the positive experience of families. When they worked well, key workers reduced the fragmented nature of services and families placed great value on keeping the same key worker from diagnosis into long-term care. Retaining these roles, where already in place, or including, if not, we would recommend, factoring into budgets to sustain and expand such roles.

Murine cardiac fibrosis localization using adaptive Bayesian cardiac strain imaging in vivo.

An adaptive Bayesian regularized cardiac strain imaging (ABR-CSI) algorithm for in vivo murine myocardial function assessment is presented. We report on 31 BALB/CJ mice (n = 17 females, n = 14 males), randomly stratified into three surgical groups: myocardial infarction (MI, n = 10), ischemia-reperfusion (IR, n = 13) and control (sham, n = 8) imaged pre-surgery (baseline- BL), and 1, 2, 7 and 14 days post-surgery using a high frequency ultrasound imaging system (Vevo 2100). End-systole (ES) radial and longitudinal strain images were used to generate cardiac fibrosis maps using binary thresholding. Percentage fibrotic myocardium (PFM) computed from regional fibrosis maps demonstrated statistically significant differences post-surgery in scar regions. For example, the MI group had significantly higher PFMRadial (%) values in the anterior mid region (p = 0.006) at Day 14 (n = 8, 42.30 ± 14.57) compared to BL (n = 12, 1.32 ± 0.85). A random forest classifier automatically detected fibrotic regions from ground truth Masson's trichrome stained histopathology whole slide images. Both PFMRadial (r = 0.70) and PFMLongitudinal (r = 0.60) results demonstrated strong, positive correlation with PFMHistopathology (p < 0.001).

Bi-allelic mutation of CTNNB1 causes a severe form of syndromic microphthalmia, persistent foetal vasculature and vitreoretinal dysplasia.

BACKGROUND: Inherited vitreoretinopathies arise as a consequence of congenital retinal vascularisation abnormalities. They represent a phenotypically and genetically heterogeneous group of disorders that can have a major impact on vision. Several genes encoding proteins and effectors of the canonical Wnt/ß-catenin pathway have been associated and precise diagnosis, although difficult, is essential for proper clinical management including syndrome specific management where appropriate. This work aimed to investigate the molecular basis of disease in a single proband born to consanguineous parents, who presented with microphthalmia, persistent foetal vasculature, posterior lens vacuoles, vitreoretinal dysplasia, microcephaly, hypotelorism and global developmental delay, and was registered severely visually impaired by 5 months of age. METHODS: Extensive genomic pre-screening, including microarray comparative genomic hybridisation and sequencing of a 114 gene panel associated with cataract and congenital ophthalmic disorders was conducted by an accredited clinical laboratory. Whole exome sequencing (WES) was undertaken on a research basis and in vitro TOPflash transcriptional reporter assay was utilised to assess the impact of the putative causal variant. RESULTS: In the proband, WES revealed a novel, likely pathogenic homozygous mutation in the cadherin-associated protein beta-1 gene (CTNNB1), c.884C>G; p.(Ala295Gly), which encodes a co-effector molecule of the Wnt/ß-catenin pathway. The proband's parents were shown to be heterozygous carriers but ophthalmic examination did not detect any abnormalities. Functional assessment of the missense variant demonstrated significant reduction of ß-catenin activity. CONCLUSIONS: This is the first report of a biallelic disease-causing variation in CTNNB1. We conclude that this biallelic, transcriptional inactivating mutation of CTNNB1 causes a severe, syndromic form of microphthalmia, persistent foetal vasculature and vitreoretinal dysplasia that results in serious visual loss in infancy.

Developing, Nurturing, and Sustaining an Adolescent and Young Adult-Centered Culture of Care.

Adolescents and young adults have unique needs which differ from those of children or adults. In the United Kingdom, we have dedicated services, which are diverse in how they are managed and delivered. A multiple-case study was conducted in young people's cancer services in four geographical regions of England. Data collection included: semi-structured interviews with healthcare professionals (n = 41) and young people (n = 29); and observation (total = 120 hours). Thematic analysis was used to synthesize and interpret five emerging themes describing the way a culture of adolescent and young adult-specific care developed. To develop a cultural attitude which embraced and promoted core values, leadership was needed, as well as high patient volume accessing a service. Time was essential, an adolescent and young adult-centered culture of care does not happen overnight, it needs time and dedicated staff to evolve, but once in place, services have a significant impact on the experience of care.

Associations between diagnostic time intervals and health-related quality of life, clinical anxiety and depression in adolescents and young adults with cancer: cross-sectional analysis of the BRIGHTLIGHT cohort.

BACKGROUND: The association of diagnostic intervals and outcomes is poorly understood in adolescents and young adults with cancer (AYA). We investigated associations between diagnostic intervals and health-related quality of life (HRQoL), anxiety and depression in a large AYA cohort. METHODS: Participants aged 12-24 completed interviews post-diagnosis, providing data on diagnostic experiences and the patient-reported outcomes (PROs) HRQoL, anxiety and depression. Demographic and cancer information were obtained from clinical and national records. Six diagnostic intervals were considered. Relationships between intervals and PROs were examined using regression models. RESULTS: Eight hundred and thirty participants completed interviews. In adjusted models, across 28 of 30 associations, longer intervals were associated with poorer PROs. Patient intervals (symptom onset to first seeing a GP) of ≥1 month were associated with greater depression (adjusted odds ratio (aOR):1.7, 95% Confidence Interval (CI):1.1-2.5) compared to <1 month. ≥3 pre-referral GP consultations were associated with greater anxiety (aOR:1.6, CI:1.1-2.3) compared to 1-2 consultations. Symptom onset to first oncology appointment intervals of ≥2 months was associated with impaired HRQoL (aOR:1.8, CI:1.2-2.5) compared to <2 months. CONCLUSIONS: Prolonged diagnostic intervals in AYA are associated with an increased risk of impaired HRQoL, anxiety and depression. Identifying and delivering interventions for this high-risk group is a priority.
