RESUMEN
BACKGROUND: Scabies is a common parasitic skin condition that causes considerable morbidity globally. Clinical and epidemiological research for scabies has been limited by a lack of standardization of diagnostic methods. OBJECTIVES: To develop consensus criteria for the diagnosis of common scabies that could be implemented in a variety of settings. METHODS: Consensus diagnostic criteria were developed through a Delphi study with international experts. Detailed recommendations were collected from the expert panel to define the criteria features and guide their implementation. These comments were then combined with a comprehensive review of the available literature and the opinion of an expanded group of international experts to develop detailed, evidence-based definitions and diagnostic methods. RESULTS: The 2020 International Alliance for the Control of Scabies (IACS) Consensus Criteria for the Diagnosis of Scabies include three levels of diagnostic certainty and eight subcategories. Confirmed scabies (level A) requires direct visualization of the mite or its products. Clinical scabies (level B) and suspected scabies (level C) rely on clinical assessment of signs and symptoms. Evidence-based, consensus methods for microscopy, visualization and clinical symptoms and signs were developed, along with a media library. CONCLUSIONS: The 2020 IACS Criteria represent a pragmatic yet robust set of diagnostic features and methods. The criteria may be implemented in a range of research, public health and clinical settings by selecting the appropriate diagnostic levels and subcategories. These criteria may provide greater consistency and standardization for scabies diagnosis. Validation studies, development of training materials and development of survey methods are now required. What is already known about this topic? The diagnosis of scabies is limited by the lack of accurate, objective tests. Microscopy of skin scrapings can confirm the diagnosis, but it is insensitive, invasive and often impractical. Diagnosis usually relies on clinical assessment, although visualization using dermoscopy is becoming increasingly common. These diagnostic methods have not been standardized, hampering the interpretation of findings from clinical research and epidemiological surveys, and the development of scabies control strategies. What does this study add? International consensus diagnostic criteria for common scabies were developed through a Delphi study with global experts. The 2020 International Alliance for the Control of Scabies (IACS) Criteria categorize diagnosis at three levels of diagnostic certainty (confirmed, clinical and suspected scabies) and eight subcategories, and can be adapted to a range of research and public health settings. Detailed definitions and figures are included to aid training and implementation. The 2020 IACS Criteria may facilitate the standardization of scabies diagnosis.

OBJECTIVE: To develop a parent-reported Pediatric Rhinosinusitis Symptom Scale (PRSS) that could be used to monitor symptoms of young children with acute sinusitis in response to therapy. STUDY DESIGN: We developed an 8-item symptom severity scale and evaluated its internal reliability, construct validity, and responsiveness in children 2-12 years of age with acute sinusitis. Parents of 258 children with acute sinusitis completed the PRSS at the time of diagnosis, as a diary at home, and at the follow-up visit at days 10-12. Based on psychometric results and additional parent feedback, we revised the scale. We evaluated the revised version in 185 children with acute sinusitis. RESULTS: Correlations between the scale and reference measures on the day of enrollment were in the expected direction and of the expected magnitude. PRSS scores at the time of presentation correlated with radiographic findings (P < .001), functional status (P < .001), and parental assessment of overall symptom severity (P < .001). Responsiveness (standardized response mean) and test-retest reliability of the revised scale were good (2.17 and 0.75, respectively). CONCLUSIONS: We have developed an outcome measure to track the symptoms of acute sinusitis. Data presented here support the use of the PRSS as a measure of change in symptom burden in clinical trials of children with acute sinusitis.

Streptococcus pyogenes (or Group A Streptococcus, GAS) is a Gram-positive human pathogen responsible for a diverse array of superficial, invasive and immune-related diseases. GAS infections have historically been diseases of poverty and overcrowding, and remain a significant problem in the developing world and in disadvantaged populations within developed countries. With improved living conditions and access to antibiotics, the rates of GAS diseases in developed societies have gradually declined during the 20th century. However, genetic changes in circulating GAS strains and/or changes in host susceptibility to infection can lead to dramatic increases in the rates of specific diseases. No situations exemplify this more than the global upsurge of invasive GAS disease that originated in the 1980s and the regional increases in scarlet fever in north-east Asia and the UK. In each case, increased disease rates have been associated with the emergence of new GAS strains with increased disease-causing capability. Global surveillance for new GAS strains with increased virulence is important and determining why certain populations suddenly become susceptible to circulating strains remains a research priority. Here, we overview the changing epidemiology of GAS infections and the genetic alterations that accompany the emergence of GAS strains with increased capacity to cause disease.
RESUMEN
The Wnt signalling pathway in beta-cells has been linked to the development of type 2 diabetes. Investigating the impact of a non-canonical Wnt ligand, Wnt4, on beta-cell function we found that in INS-1 cells, Wnt4 was able to completely block Wnt3a stimulated cell growth and insulin secretion. However, despite high levels of Wnt4 protein being detected in INS-1 cells, reducing the expression of Wnt4 had no impact on cell growth or Wnt3a signalling. As such, the role of the endogenously expressed Wnt4 in beta-cells is unclear, but the data showing that Wnt4 can act as a negative regulator of canonical Wnt signalling in beta-cells suggests that this pathway could be a potential target for modulating beta-cell function.

Impetigo is common in remote Indigenous children of northern Australia, with the primary driver in this context being Streptococcus pyogenes [or group A Streptococcus (GAS)]. To reduce the high burden of impetigo, the transmission dynamics of GAS must be more clearly elucidated. We performed whole genome sequencing on 31 GAS isolates collected in a single community from children in 11 households with ⩾2 GAS-infected children. We aimed to determine whether transmission was occurring principally within households or across the community. The 31 isolates were represented by nine multilocus sequence types and isolates within each sequence type differed from one another by only 0-3 single nucleotide polymorphisms. There was evidence of extensive transmission both within households and across the community. Our findings suggest that strategies to reduce the burden of impetigo in this setting will need to extend beyond individual households, and incorporate multi-faceted, community-wide approaches.

OBJECTIVE: To determine prognostic factors that independently predict response to antimicrobial therapy in children with acute sinusitis. STUDY DESIGN: A total of 206 children meeting a priori clinical criteria for acute sinusitis who were prescribed antimicrobial therapy by their primary care provider were included. The severity of symptoms in the 8-12 days after treatment was initiated was followed with the use of a validated scale. We examined the univariate and multivariate association between factors present at the time of diagnosis (symptoms, signs, nasopharyngeal culture result, radiograph results) and time to resolution of symptoms. This study was conducted 8-10 years after the 7-valent pneumococcal conjugate vaccination was introduced but before introduction of the 13-valent pneumococcal conjugate vaccination. RESULTS: Children with proven nasopharyngeal colonization with Streptococcus pneumoniae improved more rapidly (6.5 vs 8.5 median days to symptom resolution) than those who were not colonized with S pneumoniae. Age and radiograph findings did not predict time to symptom resolution. CONCLUSIONS: In children with acute sinusitis, proven nasopharyngeal colonization with S pneumoniae at presentation independently predicted time to symptom resolution. Future randomized, placebo-controlled trials could investigate the usefulness of testing for the presence of nasopharyngeal pathogens as a predictor of response to treatment.

INTRODUCTION: Australian Indigenous children suffer a high burden of diarrhoeal disease. Nitazoxanide is an antimicrobial that has been shown to be effective against a broad range of enteropathogens. To date, its use has not been reported in the tropical Top End (northernmost part) of the Northern Territory, Australia. The objective was to describe the use of nitazoxanide at the Royal Darwin Hospital, Northern Territory, and to assess any association with the time to resolution of diarrhoea. METHODS: Eligible children (≤13 years) were identified from dispensary records as having been prescribed nitazoxanide during the audit period, 1 July 2007 to 31 March 2012. Patient demographics, symptoms, diarrheal aetiology, treatment details and clinical outcomes were obtained by chart review. RESULTS: Twenty-eight children were treated with nitazoxanide, mostly for Cryptosporidium infection associated with prolonged diarrhoea. Dehydration was evident in 27 (96%) children on admission, and 11 (41%) were underweight. Diarrhoeal duration prior to treatment was 11.5 days (6.5 days pre- and 5 days post-admission). For children ≥12 months, nitazoxanide was prescribed according to guidelines stipulated by the Centers for Disease Control and Prevention (CDC). Resolution of diarrhoea occurred a median of 2.4 days (IQR: 1.4-7.3) after starting treatment. An increase in weight for length at discharge was found for all children. CONCLUSIONS: Prompt resolution of diarrhoea without adverse outcomes suggests nitazoxanide may be an effective treatment for Cryptosporidium infection in this setting. Its role in the treatment of other causes of infectious diarrhoea needs further investigation. Randomised trials will further direct its use and determine optimal dosing regimens.

BACKGROUND: Rates of antimicrobial resistance (AMR) for some pathogens in Australia are considerably higher in rural and remote compared to urban regions. The inaugural Hot North Antimicrobial Academy was a 9-month educational programme aimed to build workforce knowledge and capacity in antimicrobial use, audit, stewardship, surveillance and drug resistance in remote primary health care. METHODS: The Academy was advertised to Aboriginal and Torres Strait Islander, regional and remote healthcare workers. Participants were Aboriginal health practitioners, nurses, pharmacists and doctors from Queensland, Northern Territory, South Australia and Western Australia working in remote primary health care with a focus on Indigenous health. Due to COVID-19 restrictions, the Academy ran virtually from February-November 2021 using Microsoft Teams. The Academy was evaluated using surveys and yarning circles to assess impact and knowledge gain. RESULTS: Participants and faculty from across Australia attended 19 lectures and mentorship sessions. Eleven participants commenced and eight (73%) completed the Academy. The Academy raised participants awareness of AMR guidelines, governance and generating change; built confidence in advocacy; grew knowledge about drug resistant infections; and created a community of AMR champions in Indigenous health. CONCLUSION: The evaluation confirmed the Academy met the needs of participants, provided opportunities to move stewardship from tertiary hospitals into Indigenous and remote clinics and developed skills in research, audit, stewardship and advocacy for all involved. All sessions were recorded for future use, with facilitation by the National Aboriginal Community Controlled Health Organisation (NACCHO) in future years.

BACKGROUND: The role of compound heterozygous genetic haemochromatosis (CHGH) (C282Y/H63D) mutations in the manifestations of iron overload is known; however, the extent of these manifestations and their associated management remain unclear. AIMS: This study evaluates the phenotypic manifestations of CHGH using laboratory and radiological biomarkers including serum ferritin/transferrin saturation, liver function tests (LFT), thyroid function tests, blood sugar level, and abdominal ultrasound (US) or computed tomography. The study also evaluates the effects of venesection therapy on these markers and its potential role in routine management of CHGH patients. METHODS: In this case-controlled study, 104 patients with HFE-C282Y/H63D compound mutations were subjected to laboratory investigations and imaging. Tests were repeated over a 4-year period before and after venesection. Data were compared between patient and control groups using paired t-tests. RESULTS: Patients showed significantly higher serum ferritin and transferrin saturations compared with controls (P = 0.002, P = 0.003). Twenty-four patients (23%) demonstrated hyperferritinaemia ≥ 1000 mmol/L. Sixty-nine patients (68%) demonstrated biochemical abnormalities on initial testing (abnormal LFT (transaminases) (51 patients, 74%) and US/computed tomography (42 patients, 61%)). A significant number of LFT and US abnormalities normalised post-venesection (80%; P = 0.000 and 52%; P = 0.005 respectively). CONCLUSIONS: Phenotypic manifestations displayed by CHGH patients can include biochemical and radiological abnormalities, which can occur at levels similar to C282Y homozygous disease (ferritin ≥ 1000 mmol/L). With venesection therapy, a large number of these abnormalities is reversible. Based on this, a non-invasive framework to assess and manage CHGH within a routine community-based clinical setting is proposed.

Thirty years after the first discovery of high-temperature submarine venting, the vast majority of the global mid-ocean ridge remains unexplored for hydrothermal activity. Of particular interest are the world's ultraslow spreading ridges that were the last to be demonstrated to host high-temperature venting but may host systems particularly relevant to prebiotic chemistry and the origins of life. Here we report evidence for previously unknown, diverse, and very deep hydrothermal vents along the approximately 110 km long, ultraslow spreading Mid-Cayman Rise (MCR). Our data indicate that the MCR hosts at least three discrete hydrothermal sites, each representing a different type of water-rock interaction, including both mafic and ultramafic systems and, at approximately 5,000 m, the deepest known hydrothermal vent. Although submarine hydrothermal circulation, in which seawater percolates through and reacts with host lithologies, occurs on all mid-ocean ridges, the diversity of vent types identified here and their relative geographic isolation make the MCR unique in the oceans. These new sites offer prospects for an expanded range of vent-fluid compositions, varieties of abiotic organic chemical synthesis and extremophile microorganisms, and unparalleled faunal biodiversity--all in close proximity.

BACKGROUND: Dysarthria after stroke is when speech intelligibility is impaired, and this occurs in half of all stroke survivors. Dysarthria often leads to social isolation, poor psychological well-being and can prevent return to work and social lives. Currently, a variety of outcome measures are used in clinical research and practice when monitoring recovery for people who have dysarthria. When research studies use different measures, it is impossible to compare results from trials and delays our understanding of effective clinical treatments. The aim of this study is to develop a core outcome set (COS) to agree what aspects of speech recovery should be measured for dysarthria after stroke (COS-Speech) in research and clinical practice. METHODS: The COS-Speech study will include five steps: (1) development of a long list of possible outcome domains of speech that should be measured to guide the survey; (2) recruitment to the COS-Speech study of three key stakeholder groups in the UK and Australia: stroke survivors, communication researchers and speech and language therapists/pathologists; (3) two rounds of the Delphi survey process; (4) a consensus meeting to agree the speech outcomes to be measured and a follow-up consensus meeting to match existing instruments/measures (from parallel systematic review) to the agreed COS-Speech; (5) dissemination of COS-Speech. DISCUSSION: There is currently no COS for dysarthria after stroke for research trials or clinical practice. The findings from this research study will be a minimum COS, for use in all dysarthria research studies and clinical practice looking at post-stroke recovery of speech. These findings will be widely disseminated using professional and patient networks, research and clinical forums as well as using a variety of academic papers, videos, accessible writing such as blogs and links on social media. TRIAL REGISTRATION: COS-Speech is registered with the Core Outcome Measures in Effectiveness Trials (COMET) database, October 2021 https://www.comet-initiative.org/Studies/Details/1959 . In addition, "A systematic review of the psychometric properties and clinical utility of instruments measuring dysarthria after stroke" will inform the consensus meeting to match measures to COS-Speech. The protocol for the systematic reviews registered with the International Prospective Register of Systematic Reviews. PROSPERO registration number: CRD42022302998 .

The multifactorial nature of head and neck squamous cell carcinoma (HNSCC) has led to increased efforts in establishing various risk factors. Well-known environmental risk factors for HNSCC include tobacco use, heavy alcohol consumption, immunosuppression, and more recently human papillomavirus infection. Familial clustering has been observed in cancers occurring at other sites, but not so much with oral squamous cell carcinoma (OSCC) without exposure to shared environmental risk factors. An unusual case of identical twins who presented with OSCC involving an identical site and exhibiting similar histological features is reported here. The two patients underwent identical surgery with curative intent, culminating in good outcomes. It appears that no other cases of identical twins with a similar presentation in time, anatomical site, and histopathology have been reported in the literature.

Children with cochlear implants are at increased risk of invasive pneumococcal disease, with national and international guidelines recommending additional pneumococcal vaccines for these children. This study aimed to examine the pneumococcal immunization status and rate of invasive pneumococcal disease in children with cochlear implants at a tertiary paediatric hospital over a 12-year period. Additionally, the impacts of vaccination reminders and a dedicated immunization clinic on pneumococcal vaccination rates were assessed. This quality improvement study included 200 children who had received a cochlear implant through the Children's Hearing Implant Program at a tertiary paediatric hospital servicing the state of Western Australia. The majority of children (88%) were not up to date with additionally recommended pneumococcal vaccinations. Over the 12-year study period, 2% of children developed invasive pneumococcal disease associated with cochlear implant infections. Generic and personalized electronic immunization reminders improved pneumococcal vaccine up-take in this paediatric cochlear implant setting from 12% (19/153) at baseline to 49% (75/153, p < 0.0001) post implementation. The value of a nurse-led dedicated immunization clinic was also demonstrated with all children (42/42, 100%) up to date with Prevenar13 and the majority (34/42, 81%) up to date with Pneumovax23 post initiation of this referral pathway. These data support the expansion of this model to other medically-at-risk paediatric groups that have been highlighted consistently to be under-vaccinated.

BACKGROUND: The impacts of the COVID-19 pandemic have been vast and are not limited to physical health. Many adolescents have experienced disruptions to daily life, including changes in their school routine and family's financial or emotional security, potentially impacting their emotional wellbeing. In low COVID-19 prevalence settings, the impact of isolation has been mitigated for most young people through continued face-to-face schooling, yet there may still be significant impacts on their wellbeing that could be attributed to the pandemic. METHODS: We report on data from 32,849 surveys from Year 7-12 students in 40 schools over two 2020 survey cycles (June/July: 19,240; October: 13,609), drawn from a study of 79 primary and secondary schools across Western Australia, Australia. The Child Health Utility Index (CHU9D) was used to measure difficulties and distress in responding secondary school students only. Using comparable Australian data collected six years prior to the pandemic, the CHU9D was calibrated against the Kessler-10 to establish a reliable threshold for CHU9D-rated distress. RESULTS: Compared to 14% of responding 12-18-year-olds in 2013/2014, in both 2020 survey cycles almost 40% of secondary students returned a CHU9D score above a threshold indicative of elevated difficulties and distress. Student distress increased significantly between June and October 2020. Female students, those in older Grades, those with few friendships or perceived poor quality friendships, and those with poor connectedness to school were more likely to score above the threshold. CONCLUSIONS: In a large dataset collected during the first year of the COVID-19 pandemic, the proportion of secondary school students with scores indicative of difficulties and distress was substantially higher than a 2013/2014 benchmark, and distress increased as the pandemic progressed, despite the low local prevalence of COVID-19. This may indicate a general decline in social and emotional wellbeing exacerbated by the events of the pandemic. TRIAL REGISTRATION: ANZCTRN (ACTRN12620000922976).

RESUMEN
BACKGROUND: Combination antibiotic therapy with an antitoxin agent, such as clindamycin, is included in some guidelines for severe, toxin-mediated Staphylococcus aureus infections. The evidence to support this practice is currently limited to in vitro, animal and observational human case-series data, with no previous randomized controlled trials (RCTs). OBJECTIVES: This pilot RCT aimed to determine the feasibility of conducting a clinical trial to examine if adjunctive clindamycin with standard therapy has greater efficacy than standard therapy alone for S. aureus infections. METHODS: We performed an investigator-initiated, open-label, multicentre, pilot RCT (ACTRN12617001416381p) in adults and children with severe S. aureus infections, randomized to standard antibiotic therapy with or without clindamycin for 7â days. RESULTS: Over 28â months, across nine sites, 127 individuals were screened and 34 randomized, including 11 children (32%). The primary outcome-number of days alive and free of systemic inflammatory response syndrome ≤14â days-was similar between groups: clindamycin (3â days [IQR 1-6]) versus standard therapy (4â days [IQR 0-8]). The 90â day mortality was 0% (0/17) in the clindamycin group versus 24% (4/17) in the standard therapy group. Secondary outcomes-microbiological relapse, treatment failure or diarrhoea-were similar between groups. CONCLUSIONS: As the first clinical trial assessing adjunctive clindamycin for S. aureus infections, this study indicates feasibility and that adults and children can be incorporated into one trial using harmonized endpoints, and there were no safety concerns. The CASSETTE trial will inform the definitive S. aureus Network Adaptive Platform (SNAP) trial, which includes an adjunctive clindamycin domain and participants with non-severe disease.
RESUMEN
Temporomandibular joint (TMJ) ankylosis is a condition in which bony or fibrous adhesion of the anatomical joint components results in loss of function. This is particularly distressing and debilitating for patients who struggle to maintain good oral hygiene, which results in additional pain, oral disease, and ultimately, a poor aesthetic profile. A retrospective chart review was carried out to document the cases of three patients who attended a single centre for the management of ankylosis of the TMJ. Consent for chart review and use of photographs was gained from each one. Charts were obtained, records reviewed, and each of the cases written up for presentation in a case series. All three underwent arthroplasty of the TMJ and insertion of Matthews devices (two patients unilateral, one bilateral). All were followed up postoperatively. They experienced significant improvements in vertical mouth opening which have been maintained to the present. The Matthews device allows movement and physiotherapy postoperatively whilst maintaining the surgically created space. This prevents impingement on the tissues placed between the glenoid fossa and mandible, and appears to prevent relapse and further ankylosis. To our knowledge, few studies to date have documented the use of the Matthews device following interpositional arthroplasty of the TMJ.

The effect of exogenous administration of lamprey GnRH-III (IGnRH-III) on gonadotropin secretion was evaluated in pigs. Six crossbred barrows (82.4 ± 3.5 kg body weight) were assigned randomly to a replicated 3 × 3 Latin square design to evaluate the effect of 0.1, 1.0 or 10.0 µg/kg body weight of exogenous IGnRH-III on LH and FSH secretion. To facilitate blood collection and infusion of IGnRH-III, barrows were catheterized in the jugular vein 1 day before initiation of experiments. Blood samples were taken at 10-min intervals for 6 h, starting 2 h before treatments were applied. Relative concentrations of LH and FSH were calculated by obtaining the ratio of the average concentration of each hormone 2 h after infusion divided by the average concentration during the 2 h before infusion. Relative concentrations of FSH after IGnRH-III infusion did not influence mean concentration of FSH at any of the doses; yet 10.0 µg/kg body weight had a significant effect on LH secretion (p < 0.01). Relative concentrations of LH averaged 1.2, 1.0 and 3.0 ng/ml (for doses of 0.1, 1.0 and 10.0 µg/kg body weight of IGnRH-III respectively). Only a dose of 10 µg/kg body weight elicited a significant LH increase that was associated with exogenous IGnRH-III infusion. We conclude that IGnRH-III is a weak GnRH agonist and at high doses, IGnRH-III has the ability to release LH but not FSH in barrows.

AIMS: Recovery approaches are identified as the overarching framework for improving mental health services for people with severe and enduring conditions. These approaches prioritise living well with long-term conditions, as evidenced by personal recovery outcomes. There is little research demonstrating how to support busy mental health teams, work in this way. This study assessed the impact of introducing a brief measure of recovery, the Hope, Agency and Opportunity (HAO), on the attitudes and behaviours of staff working in community mental health teams, to test whether routine use of such measures facilitates recovery-based practice. METHODS: Linguistic analysis assumes that language is indicative of wider attitudes and behaviours. Anonymised clinical notes recorded by community mental health team clinicians were analysed for recovery and non-recovery language, over 30 months. This covered periods before, during and after the introduction of the recovery measure. We used a single-case design (N = 1 community mental health team) and hypothesised that clinicians would use recovery-focused language more frequently, and non-recovery-focused language less frequently, following the introduction of the measure, and that these changes would be maintained at 18-month follow-up. RESULTS: Visual inspection of the data indicated that recovery-focused language increased following the introduction of the HAO, though this was not maintained at follow-up. This pattern was not supported by statistical analyses. No clear pattern of change was found for non-recovery-focused language. CONCLUSIONS: The introduction of a brief measure of recovery may have influenced staff attitudes and behaviours temporarily. Any longer term impact is likely to depend on ongoing commitment to the use of the measure, without which staff language, attitudes and behaviours return to previous levels.

BACKGROUND: Patient, Carer and Public Involvement (PCPI) should be embedded in health care research. Delivering PCPI can be challenging, but even when PCPI is carried out it is rarely reported resulting in lost opportunities for learning. This paper aims to describe PCPI in the OSCARSS study, a pragmatic-cluster randomised controlled trial with an embedded economic and process evaluation. METHODS: A carer research user group (RUG) co-developed OSCARSS to evaluate how to best deliver support to caregivers of stroke survivors. The PCPI activity involved regular meetings and preparatory work, from the initial conceptualisation of the study through to dissemination. Written reports, structured group discussions and individual interviews were carried out with the RUG and researchers to capture the added value and learning. This paper was co-authored by two of the RUG members with contributions from the wider RUG and researchers. RESULTS: The core six members of the caregiver RUG attended the majority of the meetings alongside three researchers, one of whom was the co-chief investigator. PCPI was instrumental in changing many aspects of the research protocol, design and delivery and contributed to dissemination and sharing of good practice. There were challenges due to the emotional toll when PCPI members shared their stories and the extensive time commitment. Positive experiences of learning and fulfilment were reported by the individual researchers and PCPI members. Wider organisational administrative and financial support facilitated the PCPI. The researchers' existing positive regard for PCPI and the clear focus of the group were key to the successful co-design of this research. CONCLUSIONS: The value and learning from the PCPI collaborative work with the researchers was of benefit to the study and the individuals involved. Specific PCPI influences were a challenge to pinpoint as successful co-design meant the researchers' and carers' contributions were intertwined and decision-making shared.
