'Building bridges': reflections and recommendations for co-producing health research

BACKGROUND

Co-produced research is when all stakeholders, including experts by experience and researchers, work together to conceptualise, design, deliver and disseminate research to enhance understanding and knowledge. This type of participatory inquiry is being increasingly used across health research; however, it continues to be a complex area to navigate given existing institutional structures.

MAIN BODY

We collaborated across three independent co-produced research studies to share insights, reflections, and knowledge of our work in the fields of HIV, mental health, and disability research. We co-designed and delivered a three-hour online workshop at a conference to share these reflections using the metaphor of 'building bridges' to describe our co-production journey. We generated key principles of co-production from our different experiences working in each individual research project as well as together across the three projects. Our principles are to: (1) be kind, have fun and learn from each other; (2) share power (as much as you can with people); (3) connect with people you know and don't know; (4) remain connected; and (5) use clear and simple language.

CONCLUSION

We recommend that co-produced research needs additional funding, resource, and flexibility to remain impactful and ethical. Co-produced research teams need to be mindful of traditional power structures and ensure that the process is transparent, fair, and ethical. Addressing equality, diversity, and inclusion of traditionally underrepresented groups in research is essential as are the skills, expertise, and experiences of all members of the co-production team.

Barriers and facilitators to HIV Pre-Exposure Prophylaxis (PrEP) in Specialist Sexual Health Services in the United Kingdom: A systematic review using the PrEP Care Continuum

OBJECTIVES

HIV pre-exposure prophylaxis (PrEP) delivery in the UK is inequitable; over 95% of PrEP users were men who have sex with men (MSM) despite making up less than 50% of new HIV diagnoses. We conducted a systematic review to identify modifiable barriers and facilitators to PrEP delivery in the UK among underserved populations.

METHODS

We searched bibliographic/conference databases using the terms HIV, PrEP, barriers, facilitators, underserved populations, and UK. Modifiable factors were mapped along the PrEP Care Continuum (PCC) to identify targets for interventions.

RESULTS

In total, 44 studies were eligible: 29 quantitative, 12 qualitative and three mixed-methods studies. Over half (n = 24 [54.5%]) exclusively recruited MSM, whereas 11 were in mixed populations (all included MSM as a sub-population) and the other nine were in other underserved populations (gender and ethnicity minorities, women, and people who inject drugs). Of the 15 modifiable factors identified, two-thirds were at the PrEP contemplation and PrEParation steps of the PCC. The most reported barriers were lack of PrEP awareness (n = 16), knowledge (n = 19), willingness (n = 16), and access to a PrEP provider (n = 16), whereas the more reported facilitators were prior HIV testing (n = 8), agency and self-care (n = 8). All but three identified factors were at the patient rather than provider or structural level.

CONCLUSIONS

This review highlights that the bulk of the scientific literature focuses on MSM and on patient-level factors. Future research needs to ensure underserved populations are included and prioritized (e.g. ethnicity and gender minorities, people who inject drugs) and provider and structural factors are investigated.

Caregiver perceptions and experiences of paediatric emergency department attendance during the COVID-19 pandemic: A mixed-methods study

Background

During the early stages of the COVID-19 pandemic, concerns were raised about reduced attendance at hospitals, particularly in paediatric emergency departments, which could result in preventable poorer outcomes and late presentations among children requiring emergency care. We aimed to investigate the impact of COVID-19 on health-seeking behaviour and decision-making processes of caregivers presenting to paediatric emergency services at a National Health Service (NHS) Trust in London.

Materials and methods

We conducted a mixed-methods study (survey and semi-structured interviews) across two hospital sites between November-December 2020. Data from each study were collected concurrently followed by data comparison.

Results

Overall, 100 caregivers participated in our study; 80 completed the survey only, two completed the interview only and 18 completed both. Our quantitative study found that almost two-thirds (63%, n = 62) of caregivers attended the department within two days of their child becoming ill. Our qualitative study identified three major themes which were underpinned by concepts of trust, safety and uncertainty and were assessed in relation to the temporal nature of the pandemic and the caregivers’ journey to care. We found most caregivers balanced their concerns of COVID-19 and a perceived “overwhelmed” NHS by speaking to trusted sources, predominantly general practitioners (GPs).

Conclusion

Caregivers have adapted their health-seeking behaviour throughout the pandemic as new information and guidance have been released. We identified several factors affecting decisions to attend; some existed before the pandemic (e.g., concerns for child’s health) whilst others were due to the pandemic (e.g., perceived risks of transmission when accessing healthcare services). We recommend trusted medical professionals, particularly GPs, continue to provide reassurance to caregivers to seek emergency paediatric care when required. Communicating the hospital safety procedures and the importance of early intervention to caregivers could additionally provide reassurance to those concerned about the risks of accessing the hospital environment.

Impact of daily, oral pre-exposure prophylaxis on the risk of bacterial sexually transmitted infections among cisgender women: a systematic review and narrative synthesis

Background: There are concerns that the use of pre-exposure prophylaxis (PrEP) may result in an increased incidence of sexually transmitted infections (STIs). Evidence for this is mixed and has mostly been based on reviews focussed on gay and bisexual men and transgender women, while none have summarised evidence in cisgender women. Methods: We conducted a systematic review to explore whether daily, oral PrEP use is associated with changes in bacterial STI occurrence (diagnoses or self-reported) and/or risk among HIV seronegative cisgender women (ciswomen). The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) tool. Results: We included 11 full text articles in a narrative synthesis, with the studies published between 2012 and 2021. The studies were mostly based in Africa (n=7, 63.6%) and reported on 3168 ciswomen using PrEP aged 16-56 years. Studies had marked differences in variables, including measurements and definitions (e.g., STI type) and limited data available looking specifically at ciswomen, principally in studies with both male and female participants. The limited evidence suggests that PrEP use is not associated with increased STI rates in ciswomen generally; however, adolescent girls and young women in Sub Saharan Africa have a higher prevalence of bacterial STIs prior to PrEP initiation, compared to adult ciswomen and female sex workers. Conclusions: We suggest future PrEP research make efforts to include ciswomen as study participants and report stratified results by gender identity to provide adequate data to inform guidelines for PrEP implementation.

Influence of Material Deprivation on Clinical Outcomes Among People Living with HIV in High-Income Countries: A Systematic Review and Meta-analysis

Despite developments in HIV treatment and care, disparities persist with some not fully benefiting from improvements in the HIV care continuum. We conducted a systematic review to explore associations between social determinants and HIV treatment outcomes (viral suppression and treatment adherence) in high-income countries. A random effects meta-analysis was performed where there were consistent measurements of exposures. We identified 83 observational studies eligible for inclusion. Social determinants linked to material deprivation were identified as education, employment, food security, housing, income, poverty/deprivation, socioeconomic status/position, and social class; however, their measurement and definition varied across studies. Our review suggests a social gradient of health persists in the HIV care continuum; people living with HIV who reported material deprivation were less likely to be virologically suppressed or adherent to antiretrovirals. Future research should use an ecosocial approach to explore these interactions across the lifecourse to help propose a causal pathway.

A qualitative exploration of participant and investigator perspectives from the TRED-HF trial

AIMS

We explored the experiences and motivations of participants and staff who took part in the TRED-HF trial (Therapy withdrawal in REcovered Dilated cardiomyopathy).

METHODS AND RESULTS

We conducted a qualitative study, using semi-structured interviews, with participants (n = 12) and the research team (n = 4) from the TRED-HF trial. Interviews were carried out in 2019 and were audio-recorded and transcribed. Data were managed using NVivo and analysed using framework analysis. A patient representative provided guidance on the interpretation of findings and presentation of themes to ensure these remained meaningful, and an accurate representation, to those living with dilated cardiomyopathy. Three key themes emerged from the data: (i) perception of health; (ii) experiences and relationships with healthcare services and researchers; and (iii) perception of risk. Study participants held differing perceptions of their health; some did not consider themselves to have a heart condition or disagreed with the medical term 'heart failure'. Relationships between participants, research staff, and clinical management teams influenced participants' experiences and decision making during the trial, including following clinical advice. There were differences in participants' perceptions of risk and their decisions to take heart failure medication after the trial was completed. Although the original TRED-HF trial did not provide the results many had hoped for, a strong motivator for taking part was the opportunity to withdraw medication in a safely monitored environment which had been previously considered by some participants before. Investigators acknowledged that the insights gained from the study can now be used to support evidence-based conversations with patients.

CONCLUSIONS

For people whose dilated cardiomyopathy is in remission, decisions to continue, reduce, or stop their medication are influenced by perceptions of personal health, perceive risk and the important of work, employment, recreation, relationships, and long-term plans. The unique relationship between patient and cardiologist provides opportunities to promote honest discussion about adherence to medication and personalized long-term management.

Harlequin syndrome in a young girl: An opportunity to rethink the terminology

Harlequin syndrome is a rare disorder of the autonomic nervous system, presenting as unilateral reduced flushing and sweating of the face induced by exercise, stress, or heat. It is caused by a cervical sympathetic deficit located at the preganglionic or postganglionic level on the non-flushing side. We present a case of an 8 year old with harlequin syndrome and review the other dermatological conditions for which the term "harlequin" is part of the nomenclature.

Usability and Acceptability of Home-based Self-testing for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Antibodies for Population Surveillance

BACKGROUND

This study assesses acceptability and usability of home-based self-testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies using lateral flow immunoassays (LFIA).

METHODS

We carried out public involvement and pilot testing in 315 volunteers to improve usability. Feedback was obtained through online discussions, questionnaires, observations, and interviews of people who tried the test at home. This informed the design of a nationally representative survey of adults in England using two LFIAs (LFIA1 and LFIA2) which were sent to 10 600 and 3800 participants, respectively, who provided further feedback.

RESULTS

Public involvement and pilot testing showed high levels of acceptability, but limitations with the usability of kits. Most people reported completing the test; however, they identified difficulties with practical aspects of the kit, particularly the lancet and pipette, a need for clearer instructions and more guidance on interpretation of results. In the national study, 99.3% (8693/8754) of LFIA1 and 98.4% (2911/2957) of LFIA2 respondents attempted the test and 97.5% and 97.8% of respondents completed it, respectively. Most found the instructions easy to understand, but some reported difficulties using the pipette (LFIA1: 17.7%) and applying the blood drop to the cassette (LFIA2: 31.3%). Most respondents obtained a valid result (LFIA1: 91.5%; LFIA2: 94.4%). Overall there was substantial concordance between participant and clinician interpreted results (kappa: LFIA1 0.72; LFIA2 0.89).

CONCLUSIONS

Impactful public involvement is feasible in a rapid response setting. Home self-testing with LFIAs can be used with a high degree of acceptability and usability by adults, making them a good option for use in seroprevalence surveys.

Patient data-sharing for immigration enforcement: a qualitative study of healthcare providers in England

AIM

To explore healthcare providers' perceptions and experiences of the implications of a patient data-sharing agreement between National Health Service (NHS) Digital and the Home Office on access to NHS services and quality of care received by migrant patients in England.

DESIGN

A qualitative study using semi-structured interviews, thematic analysis and constant-comparison approach.

PARTICIPANTS

Eleven healthcare providers and one non-clinical volunteer working in community or hospital-based settings who had experience of migrants accessing NHS England services. Interviews were carried out in 2018.

SETTING

England.

RESULTS

Awareness and understanding of the patient data-sharing agreement varied among participants, who associated this with a perceived lack of transparency by the government. Participants provided insight into how they thought the data-sharing agreement was negatively influencing migrants' health-seeking behaviour, their relationship with clinicians and the safety and quality of their care. They referred to the policy as a challenge to their core ethical principles, explicitly patient confidentiality and trust, which varied depending on their clinical specialty.

CONCLUSIONS

A perceived lack of transparency during the policy development process can result in suspicion or mistrust towards government among the health workforce, patients and public, which is underpinned by a notion of power or control. The patient data-sharing agreement was considered a threat to some of the core principles of the NHS and its implementation as adversely affecting healthcare access and patient safety. Future policy development should involve a range of stakeholders including civil society, healthcare professionals and ethicists, and include more meaningful assessments of the impact on healthcare and public health.

The limitations of dermoscopy: false-positive and false-negative tumours

Dermoscopy has been documented to increase the diagnostic accuracy of clinicians evaluating skin tumours, improving their ability to detect skin cancer and better recognize benign moles. However, dermoscopically 'false-positive' and 'false-negative' tumours do exist. False-positive diagnosis usually leads to unnecessary excisions. False-negative diagnosis is much more dangerous, as it might result in overlooking a cancer, with severe undesirable consequences for the patient and the physician. Therefore, management strategies should mainly focus on addressing the risk of dermoscopically false-negative tumours. The most frequent benign tumours that might acquire dermatoscopic characteristics suggestive of malignancy are seborrhoeic keratosis (SK), including solar lentigo, melanoacanthoma, irritated, clonal and regressive SK, angioma (mainly thrombosed angioma and angiokeratoma), dermatofibroma, benign adnexal tumours and naevi (Clark, Spitz, recurrent, combined, sclerosing). The most useful clues to recognize these tumours are the following: solar lentigo - broad network; melanoacanthoma - sharp border; irritated SK - regularly distributed white perivascular halos; clonal SK - classic SK criteria; regressive SK - remnants of SK; targetoid haemosiderotic haemangioma - dark centre and reddish periphery; thrombosed angioma - sharp demarcation; angiokeratoma - dark lacunae; atypical dermatofibromas - palpation; follicular tumours - white colour; sebaceous tumours - yellow colour; Clark naevi - clinical context; Spitz/Reed naevi - age; combined naevi - blue central area; recurrent naevi - pigmentation within the scar; sclerosing naevi - age and location on the upper back; blue naevi - history. Malignant tumours that might mimic benign ones and escape detection are melanoma (in situ, nevoid, spitzoid, verrucous, regressive, amelanotic), squamous cell carcinoma (mainly well-differentiated variants) and rarely basal cell carcinoma (non-pigmented variants). The most useful clues to recognize the peculiar melanoma subtypes are as follows: melanoma in situ - irregular hyperpigmented areas; nevoid melanoma - history of growth; spitzoid melanoma - age; verrucous melanoma - blue-black sign; regressive melanoma - peppering or scar-like depigmentation; amelanotic melanoma - pink colour, linear irregular vessels, dotted vessels. In this article, we summarized the most frequent dermoscopic variations of common skin tumours that are often misinterpreted, aiming to assist clinicians to reduce the number of false diagnoses.

Are patients with coeliac disease seeking alternative therapies to a gluten-free diet?

BACKGROUND & AIMS

The cornerstone of treatment for coeliac disease is a gluten-free diet (GFD). However, adherence to a GFD is variable. Recently investigators have been reporting their preliminary findings using novel therapies. In addition, there is a growing interest in the use of complementary or alternative medicine (CAM) in gastrointestinal illnesses. These observations suggest that patients with coeliac disease may be dissatisfied with a GFD and possibly are seeking/using alternative therapies for their disease. Our aim was to assess the satisfaction levels of adults with coeliac disease towards a GFD, their use of oral CAM and views regarding novel therapies.

METHODS

310 patients with coeliac disease completed a questionnaire survey while attending their out-patient appointment. The control group comprised 477 individuals.

RESULTS

Over 40% of patients with coeliac disease were dissatisfied with a GFD. The frequency of CAM use in patients with coeliac disease was 21.6% (67/310) vs 27% in the control group (129/477), p=0.09. All patients expressed an interest in novel therapies, with a vaccine being the first choice in 42% of patients, 35% and 23% for anti- zonulin and peptidases, respectively. Universally, patients placed genetically modified wheat as the lowest preference.

CONCLUSIONS

A large proportion of patients with coeliac disease are dissatisfied with a GFD. Coeliac patients are not taking CAM any more than controls, suggesting they do not view CAM as an alternative to a GFD. However, all the patients in this survey were keen to consider novel therapies, with a vaccine being the most preferred option.

Detection of hereditary bisalbuminemia in a Greek family by capillary zone electrophoresis

It is presented herein a case of a family, four members of which suffer from hereditary bisalbuminemia. The abnormality was initially detected in a 29-year old male, by serum protein electrophoresis (SPE), during the investigation for possible multiple sclerosis. SPE also revealed the presence of a double albumin band in sera of the patient's sister, father and grandmother, almost confirming the inherited (genetic) form of bisalbuminemia. Possible causes related with the acquired form of bisalbuminemia were excluded for all examined individuals. SPE was performed by both automatic capillary zone electrophoresis and agaroze gel electrophoresis. All tested samples were immunofixated with special antisera, in order to exclude the presence of monoclonal fractions. Total albumin, total proteins and immunoglobulins varied in normal ranges. The relative mobility of the albumin variant was determined by a simple mixing experiment, which gave evidence of the fast-type form of inherited bisalbuminemia. This is the first report of hereditary bisalbuminemia in Greece.

Unsuspected breast carcinoma presenting as orbital complication of rhinosinusitis

We report a rare clinical presentation of breast carcinoma metastasis to the ethmoid sinuses, orbit and cavernous sinus in a 70-year-old lady with unsuspected breast carcinoma who presented with clinical features of acute ethmoiditis, orbital cellulitis and cavernous sinus thrombosis. The patient underwent endoscopic ethmoidectomy and histology of the necrotic tissue from the ethmoidal cells was positive for endovascular neoplastic emboli. Subsequent examination revealed a large mass in the left breast, tethered to the skin, which was histologically confirmed to be a carcinoma. The patient died 2 months post-diagnosis. To our knowledge, this is the third case manifesting with combined features of ethmoiditis, orbital cellulitis and cavernous sinus syndrome from an unsuspected breast carcinoma. This case highlights the importance of imaging and thorough physical examination when a dramatic clinical picture presents in the paranasal sinuses of an otherwise healthy individual. Such manifestation of breast carcinoma is difficult to diagnose, and therefore, a high index of suspicion should be maintained. Skull base metastases from breast carcinoma behave aggressively and if diagnosed early, treatment may prolong survival and improve quality of life.

Pattern of semantic errors in autism: a brief research report

Semantic or vocabulary errors were measured among children with autism and mild learning disability and children with mild learning disability only (six children of 7.9-8.7 years in each group), testing the hypothesis that these were common in both groups. Different variables were investigated such as breadth of vocabulary and number of vocabulary errors, type of paraphasias, and mechanisms used to name the meanings that children were not aware of or could not recall, and the particular meanings that were difficult for each group. Preliminary findings showed that vocabulary errors were similar in both groups, except under-extension, which was not used by the autism group. Children with autism tended to use all mechanisms in order to name something they did not know and to focus on parts of the object in order to name it, while unknown words were similar in both groups.

War trauma and psychopathology in Bosnian refugee children

This paper describes the pattern of psychopathology in a sample of 95 children of 8-13 years, who had experienced war in Bosnia. The children were assessed with a battery of standardised measures during a psychosocial support programme in Northern Greece. They either came from refugee families (44%) or had suffered significant family loss (a parent had been killed in 28% and the father was injured or absent in 27% of cases). Children recalled a substantial number of war traumatic experiences. According to previously established cut-off scores on self-report measures, 45 children (47%) scored within the clinical range on the Depression Self-Rating Scale for Children, 28 (23%) on the Revised Children's Manifest Anxiety Scale, and 65 (28%) on the Impact of Event Scale (IES) measuring PTSD reactions. There was a significant association between the number of war traumatic experiences and the intrusion and avoidance scores on the IES. The findings are discussed in relation to setting up intervention programmes for children victims of war and their families.

Comparative study on cytogenetic effects by diplatinum complexes of the ligands of naphthazarine and squaric acid in human lymphocytes

The effect of diplatinum complexes of the binucleating ligands of naphthazarine and squaric acid on Sister Chromatid Exchange (SCE) rates and human lymphocyte proliferation kinetics was studied. Squarodicisplatinum complex I, naphthazarindicisplatinum and squarodicisplatinum complex II induce cytotoxic effects as can be deduced from the resulted induction of SCEs and the produced cell division delays. Squarodicisplatinum complex I was found to be on a molar basis the most effective in causing markedly increased SCE rates and cell division delays. Cis-diaminodichloride platinum was found to be next in order of effectiveness with naphthazarindicisplatinum and squarodicisplatinum complex II following. Naphthazarine and SQA were found to be ineffective on induction of SCEs.
