Robustness of radiomic features in <sup>123</sup>I-ioflupane-dopamine transporter single-photon emission computer tomography scan

by Viktor Laskov, David Rothbauer, Hana Malikova

Radiomic features are usually used to predict target variables such as the absence or presence of a disease, treatment response, or time to symptom progression. One of the potential clinical applications is in patients with Parkinson’s disease. Robust radiomic features for this specific imaging method have not yet been identified, which is necessary for proper feature selection. Thus, we are assessing the robustness of radiomic features in dopamine transporter imaging (DaT). For this study, we made an anthropomorphic head phantom with tissue heterogeneity using a personal 3D printer (polylactide 82% infill); the bone was subsequently reproduced with plaster. A surgical cotton ball with radiotracer (123I-ioflupane) was inserted. Scans were performed on the two-detector hybrid camera with acquisition parameters corresponding to international guidelines for DaT single photon emission tomography (SPECT). Reconstruction of SPECT was performed on a clinical workstation with iterative algorithms. Open-source LifeX software was used to extract 134 radiomic features. Statistical analysis was made in RStudio using the intraclass correlation coefficient (ICC) and coefficient of variation (COV). Overall, radiomic features in different reconstruction parameters showed a moderate reproducibility rate (ICC = 0.636, p 0.9, p

Creating a psychosocial intervention combining growth mindset and implementation intentions (GMII) to reduce alcohol consumption: A mixed method approach

by Sacha Parada, Bérengère Rubio, Elsa Taschini, Xavier Laqueille, Malika El Youbi, Pierre Paris, Bernard Angerville, Alain Dervaux, Jean-François Verlhiac, Eve Legrand

This work aimed at creating a psychosocial intervention based on growth mindset theory and implementation intention strategies, in order to reduce alcohol consumption among users in the general population, and the clinical population of individuals with alcohol use disorder. A mixed method approach was used, combining qualitative and quantitative research methods among both populations. Four focus groups were first conducted to extract arguments in favor of a malleable view of alcohol consumption (study 1A), situations that trigger the desire to drink alcohol, as well as strategies used by people to counteract this need (study 1B). Data were analyzed using reflective thematic analysis in line with the scientific literature on alcohol consumption. The results were used to create a questionnaire scoring the relevance of each argument, situation and strategy (study 2). The 20 best scored arguments, situations and strategies were selected to create the intervention. The created intervention consisted in a popularized scientific article describing alcohol consumption as malleable, including the selected arguments and followed by two internalization exercises. Then, a volitional help sheet included the selected situations and solutions was presented, allowing forming up to three plans. The discussion focused on the added value of the created material compared to pre-existing tools in the literature, and presents plans to test the intervention in a future study.

Implementing HLA-B*58:01 testing prior to allopurinol initiation in Malaysian primary care setting: A qualitative study from doctors’ and patients’ perspective

by Wei Leik Ng, Norita Hussein, Chirk Jenn Ng, Nadeem Qureshi, Yew Kong Lee, Zhenli Kwan, Boon Pin Kee, Sue-Mian Then, Tun Firzara Abdul Malik, Fatimah Zahrah Mohd Zaidan, Siti Umi Fairuz Azmi

Introduction

Allopurinol, the first-line treatment for chronic gout, is a common causative drug for severe cutaneous adverse reactions (SCAR). HLA-B*58:01 allele was strongly associated with allopurinol-induced SCAR in Asian countries such as Taiwan, Japan, Thailand and Malaysia. HLA-B*58:01 screening before allopurinol initiation is conditionally recommended in the Southeast-Asian population, but the uptake of this screening is slow in primary care settings, including Malaysia. This study aimed to explore the views and experiences of primary care doctors and patients with gout on implementing HLA-B*58:01 testing in Malaysia as part of a more extensive study exploring the feasibility of implementing it routinely.

Methods

This qualitative study used in-depth interviews and focus group discussions to obtain information from patients with gout under follow-up in primary care and doctors who cared for them. Patients and doctors shared their gout management experiences and views on implementing HLA-B*58:01 screening in primary care. Data were coded and analysed using thematic analysis.

Results

18 patients and 18 doctors from three different healthcare settings (university hospital, public health clinics, private general practitioner clinics) participated. The acceptability to HLA-B*58:01 screening was good among the doctors and patients. We discovered inadequate disclosure of severe side effects of allopurinol by doctors due to concerns about medication refusal by patients, which could potentially be improved by introducing HLA-B*58:01 testing. Barriers to implementation included out-of-pocket costs for patients, the cost-effectiveness of this implementation, lack of established alternative treatment pathway besides allopurinol, counselling burden and concern about genetic data security. Our participants preferred targeted screening for high-risk populations instead of universal screening.

Conclusion

Implementing HLA-B*58:01 testing in primary care is potentially feasible if a cost-effective, targeted screening policy on high-risk groups can be developed. A clear treatment pathway for patients who test positive should be made available.

Facilitators and barriers to pressure injury prevention, management and education: Perspectives from healthcare professionals—A qualitative study

Abstract

This study aims to (1) characterize healthcare professionals' (HCPs') experiences related to the prevention and management of pressure injuries (PIs) and (2) explore the educational needs of individuals with a past or current history of PIs and their caregivers from the perspective of HCPs. This is a qualitative descriptive study. HCPs (n = 18) were interviewed using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and coded using NVivo. Three overarching themes encompassing various dimensions were identified: (1) Facilitators related to PI prevention and management, (2) Challenges related to PI prevention and management and (3) Recommendations for improving patient and caregiver PI education. HCPs identified a greater number of challenges than facilitators related to PI care. This study emphasizes the importance of a patient-centred and interprofessional approach to patient education for PI prevention and management. Meaningful interventions focused on the patient may improve health literacy and empower patients and caregivers in PI care. Investing in preventive measures and raising awareness are crucial to reducing PI incidence. The findings have implications for HCPs and researchers seeking to enhance patient care and promote effective PI prevention strategies.

Objectives

To engage children who have experienced cancer, childhood cancer survivors, their families and professionals to systematically identify and prioritise research questions about childhood cancer to inform the future research agenda.

Design

James Lind Alliance Priority Setting Partnership.

Setting

UK health service and community.

Methods

A steering group oversaw the initiative. Potential research questions were collected in an online survey, then checked to ensure they were unanswered. Shortlisting via a second online survey identified the highest priority questions. A parallel process with children was undertaken. A final consensus workshop was held to determine the Top 10 priorities.

Participants

Children and survivors of childhood cancer, diagnosed before age 16, their families, friends and professionals who work with this population.

Results

Four hundred and eighty-eight people submitted 1299 potential questions. These were refined into 108 unique questions; 4 were already answered and 3 were under active study, therefore, removed. Three hundred and twenty-seven respondents completed the shortlisting survey. Seventy-one children submitted questions in the children’s surveys, eight children attended a workshop to prioritise these questions. The Top 5 questions from children were taken to the final workshop where 23 questions in total were discussed by 25 participants (young adults, carers and professionals). The top priority was ‘can we find effective and kinder (less burdensome, more tolerable, with fewer short and long-term effects) treatments for children with cancer, including relapsed cancer?’

Conclusions

We have identified research priorities for children’s cancer from the perspectives of children, survivors, their families and the professionals who care for them. Questions reflect the breadth of the cancer experience, including diagnosis, relapse, hospital experience, support during/after treatment and the long-term impact of cancer. These should inform funding of future research as they are the questions that matter most to the people who could benefit from research.

Introduction

Fifty per cent of patients with cancer require radiotherapy during their disease course, however, only 10%–40% of patients in low-income and middle-income countries (LMICs) have access to it. A shortfall in specialised workforce has been identified as the most significant barrier to expanding radiotherapy capacity. Artificial intelligence (AI)-based software has been developed to automate both the delineation of anatomical target structures and the definition of the position, size and shape of the radiation beams. Proposed advantages include improved treatment accuracy, as well as a reduction in the time (from weeks to minutes) and human resources needed to deliver radiotherapy.

Methods

ARCHERY is a non-randomised prospective study to evaluate the quality and economic impact of AI-based automated radiotherapy treatment planning for cervical, head and neck, and prostate cancers, which are endemic in LMICs, and for which radiotherapy is the primary curative treatment modality. The sample size of 990 patients (330 for each cancer type) has been calculated based on an estimated 95% treatment plan acceptability rate. Time and cost savings will be analysed as secondary outcome measures using the time-driven activity-based costing model. The 48-month study will take place in six public sector cancer hospitals in India (n=2), Jordan (n=1), Malaysia (n=1) and South Africa (n=2) to support implementation of the software in LMICs.

Ethics and dissemination

The study has received ethical approval from University College London (UCL) and each of the six study sites. If the study objectives are met, the AI-based software will be offered as a not-for-profit web service to public sector state hospitals in LMICs to support expansion of high quality radiotherapy capacity, improving access to and affordability of this key modality of cancer cure and control. Public and policy engagement plans will involve patients as key partners.

Sikh and Muslim perspectives on kidney transplantation: phase 1 of the DiGiT project - a qualitative descriptive study

Por: Brand · S. · Daga · S. · Mistry · K. · Morsy · M. · Bagul · A. · Hamer · R. · Malik · S.
Objectives

Kidney transplantation offers patients better quality of life and survival compared with dialysis. The risk of end stage renal disease is higher among ethnic minorities and they experience longer wait times on transplant lists. This inequality stems from a high need for kidney transplantation combined with a low rate of deceased donation among ethnic minority groups. This study aimed to explore the perspectives around living donor kidney transplantation of members of the Sikh and Muslim communities with an aim to develop a digital intervention to overcome any barriers.

Design

A qualitative descriptive study using in person focus groups.

Setting

University Teaching Hospital and Transplant Centre.

Participants

Convenience sampling of participants from the transplant population. Three focus groups were held with 20 participants, all were of South Asian ethnicity belonging to the Sikh and Muslim communities.

Methods

Interviews were digitally audio-recorded and transcribed verbatim; transcripts were analysed thematically.

Results

Four themes were identified: (a) religious issues; (b) lack of knowledge within the community; (c) time; (d) cultural identification with transplantation.

Conclusions

Not only is the information given and when it is delivered important, but also the person giving the information is crucial to enhance consideration of live donor kidney transplantation. Information should be in a first language where possible and overtly align to religious considerations. A more integrated approach to transplantation counselling should be adopted which includes healthcare professionals and credible members of the target cultural group.

Dietary replacement of soybean meal with black soldier fly larvae meal in juvenile <i>Labeo rohita</i> and <i>Catla catla</i>: Effects on growth, nutritional quality, oxidative stress biomarkers and disease resistance

by Shafaq Fatima, Ayesha Afzal, Hamna Rashid, Saba Iqbal, Rosheen Zafar, Komal Khalid, Ayman Rauf, Maryam Majeed, Aqsa Malik, Chris G. Carter

This experiment aimed to investigate the effects of partial substitution of crude protein from soybean meal (SBM) with black soldier fly (Hermetia illucens) larvae meal (BSFLM) in juvenile rohu (Labeo rohita) and catla (Catla catla). Four isonitrogenous diets (23% crude protein) were formulated to replace 0% (T0), 40% (T40), 80% (T80) and 100% (T100) crude protein from SBM with BSFLM. Triplicate groups of each species (10 fish per replicate) were fed in an eight week growth experiment. After final sampling (n = 20 fish per dietary group), the remaining fish were exposed to bacterial (Staphylococcus aureus) challenge (0.80 CFU/ml) for 15 days. Rohu fed with BSFLM substituted diets showed significantly higher growth and feed conversion ratio as compared to those in T0. Catla fed with BSFLM substituted diets showed slightly higher growth indices. The growth response of rohu to BSFLM substitution was better than that noted in catla in all groups. The chemical composition, amino acids and fatty acids profile, haematological and biochemical parameters, levels of liver function enzymes measured in T0, T40, T80 and T100 were similar between four dietary groups in both species. However, the maximum value of cholesterol and triglycerides were noted in T100 both in catla and rohu. The values of lauric acid, α-linolenic acid, decosahexanoic acid, n3:n6 fatty acids ratio progressively increased with dietary increase of BSFLM in both species. At end of the growth experiment, the levels of catalase, superoxide dismutase and lysozyme increased linearly with the inclusion of BSFLM in both species while malondialdehyde showed similar values between different groups. However, catalase, and superoxide dismutase increased (T0
