Introduction The incidence of cutaneous malignant melanoma is increasing. Internationally, there is evidence of an association between melanoma incidence and higher socioeconomic status (SES). This study aims to assess the characteristics of patients with melanoma in NI, and correlate to SES. Method Retrospective review of electronic records for patients undergoing surgery for melanoma at the Northern Ireland Plastic Surgery Unit from August 2015 to March 2020. Patients were identified from theatre records and a prospectively collected sentinel lymph node database. The NI Multiple Deprivation Measure 2017 was used to measure SES. Results 440 patients were included (F = 54%, M = 46%). Mean age=63 (M = 67, F = 59). Mean Breslow Depth (BD) = 2.61mm (Range 0.17 – 27mm). Females had significantly thinner tumours at presentation (mean BD 2.16mm. vs 3.1mm in males, p = 0.001). In males the commonest sites were head and neck (36%) and back (23%). In females, the commonest sites were lower limb (42%) and upper limb (23%). There was a positive correlation between higher SES and increased incidence of melanoma (correlation coefficient (CC) 0.922), but this did not correlate with an increase in Breslow depth (CC -0.020). Conclusions This study provides important information on melanoma in NI, including gender and site variances. Females were more commonly affected and were a mean of 8 years younger than males at diagnosis but presented with significantly thinner tumours. Unlike the rest of the UK, the commonest site in males was the head and neck. Higher SES was related to higher incidence of melanoma but with presentation at an earlier stage of disease.

Introduction and Aims The aim of this systematic review is to provide an up-to-date evaluation of the role and test performance of sentinel lymph node biopsy (SLNB) in the head and neck. Method This review follows the PRISMA guidelines. Database searches for MEDLINE and EMBASE were constructed to retrieve human studies published between 1st January 2010 and 1st July 2020 assessing the role and accuracy of sentinel lymph node biopsy in cutaneous malignant melanoma of the head and neck. Articles were independently screened by two reviewers and critically appraised using the MINORS criteria. The primary outcomes consisted of the sentinel node identification rate and test-performance measures, including the false-negative rate and the posttest probability negative. Results A total of 27 studies, including 4688 patients, met the eligibility criteria. Statistical analysis produced weighted summary estimates for the sentinel node identification rate of 97.3% (95% CI, 95.9% to 98.6%), the false-negative rate of 21.3% (95% CI, 17.0% to 25.4%) and the posttest probability negative of 4.8% (95% CI, 3.9% to 5.8%). Discussion Sentinel lymph node biopsy is accurate and feasible in the head and neck. Despite technical improvements in localisation techniques, the false negative rate remains disproportionately higher than for melanoma in other anatomical sites.

We compared point of care (POC) with laboratory glycated haemoglobin (HbA1c) testing among newly diagnosed TB patients to assess POC test accuracy, safety and acceptability in settings in which immediate access to DM services may be difficult. METHODS: We measured POC and accredited laboratory HbA1c (using high-performance liquid chromatography) in 1942 TB patients aged 18 years recruited from Peru, Romania, Indonesia and South Africa. We calculated overall agreement and individual variation (mean +/- 2 standard deviations) stratified by country, age, sex, body mass index (BMI), HbA1c level and comorbidities (anaemia, human immunodeficiency virus [HIV]). We used an error grid approach to identify disagreement that could raise significant concerns. RESULTS: Overall mean POC HbA1c values were modestly higher than laboratory HbA1c levels by 0.1% units (95%CI 0.1-0.2); however, there was a substantial discrepancy for those with severe anaemia (1.1% HbA1c, 95%CI 0.7-1.5). For 89.6% of 1942 patients, both values indicated the same DM status (no DM, HbA1c

Background People with diabetes have an increased risk of developing active tuberculosis (TB) and are more likely to have poor TB-treatment outcomes, which may impact on control of TB as the prevalence of diabetes is increasing worldwide. Blood transcriptomes are altered in patients with active TB relative to healthy individuals. The effects of diabetes and intermediate hyperglycemia (IH) on this transcriptomic signature were investigated to enhance understanding of immunological susceptibility in diabetes-TB comorbidity. Methods Whole blood samples were collected from active TB patients with diabetes (glycated hemoglobin [HbA1c] ≥6.5%) or IH (HbA1c = 5.7% to, Our study shows that people with diabetes and tuberculosis have altered peripheral immune profiles compared to people with only tuberculosis, and that these differences also exist in patients with intermediate hyperglycemia.

Nurse–patient therapeutic engagement on acute mental health wards is beneficial to service users’ outcomes and nurses’ job satisfaction. However, engagement is not always fulfilled in practice and interventions to improve engagement are sparse and ineffective. We explored the experiences of service users, carers, and clinicians drawing from 80 hours of non-participant observations in an acute mental health ward and semi-structured interviews with 14 service users, two carers, and 12 clinicians. Analysis of these data resulted in 28 touchpoints (emotionally significant moments) and eight overarching themes. Service users, carers, and clinicians identified a lack of high-quality, person-centred, collaborative engagement and recognized and supported efforts to improve engagement in practice. Potential solutions to inform future intervention development were identified. Our findings align with previous research highlighting negative experiences and support the need to develop multicomponent interventions through participatory methods.

Background Lack of high-quality nurse-patient therapeutic engagement is a longstanding problem on acute mental health wards, with a dearth of interventions to address this. A collaborative, theory-driven approach to developing and implementing complex interventions is more likely to be effective and sustainable. This paper describes an integrated co-design-behaviour change approach which developed the Let’s Talk intervention toolkit for improving the quality of therapeutic engagement on acute mental health wards. Methods We describe a theory-driven approach to co-designing an intervention by adapting and integrating Experience-based Co-design (EBCD) with the Behaviour Change Wheel (BCW). Fieldwork was informed by the results of a systematic integrative review and was guided by our co-design-behaviour change approach. It was conducted over 12-months at an acute mental health organisation in England. We undertook semi-structured interviews with 14 service users (seven of which were filmed), two carers and 12 clinicians, 80 hours of non-participant observations and a facilitated intervention co-design process that involved two feedback workshops, one joint co-design workshop and seven small co-design team meetings. Data analysis comprised the identification of touchpoints and use of the BCW and behaviour change technique taxonomy to inform intervention development. Results The co-designed Let’s Talk toolkit addressed four joint priorities for change: 1) improve communication with withdrawn people; 2) nurses to help service users help themselves; 3) nurses to feel confident when engaging with service users; 4) improving team relations and ward culture. Intervention functions included training, education, enablement, coercion and persuasion; 14 behaviour change techniques supported these functions. We detail how we implemented our integrated co-design-behaviour change approach with service users, carers and clinicians to co-design the toolkit to improve nurse-patient therapeutic engagement. Conclusions Our theory-driven approach enhances both EBCD and the BCW. It introduces a robust theoretical approach to guide intervention development within the co-design process and sets out how to meaningfully involve service users and other stakeholders when designing and implementing complex interventions.

Objective\ud To evaluate the performance of diagnostic tools for diabetes mellitus, including laboratory methods and clinical risk scores, in newly-diagnosed pulmonary tuberculosis patients from four middle-income countries.\ud \ud Methods\ud In a multicentre, prospective study, we recruited 2185 patients with pulmonary tuberculosis from sites in Indonesia, Peru, Romania and South Africa from January 2014 to September 2016. Using laboratory-measured glycated haemoglobin (HbA1c) as the gold standard, we measured the diagnostic accuracy of random plasma glucose, point-of-care HbA1c, fasting blood glucose, urine dipstick, published and newly derived diabetes mellitus risk scores and anthropometric measurements. We also analysed combinations of tests, including a two-step test using point-of-care HbA1cwhen initial random plasma glucose was ≥ 6.1 mmol/L.\ud \ud Findings\ud The overall crude prevalence of diabetes mellitus among newly diagnosed tuberculosis patients was 283/2185 (13.0%; 95% confidence interval, CI: 11.6–14.4). The marker with the best diagnostic accuracy was point-of-care HbA1c (area under receiver operating characteristic curve: 0.81; 95% CI: 0.75–0.86). A risk score derived using age, point-of-care HbA1c and random plasma glucose had the best overall diagnostic accuracy (area under curve: 0.85; 95% CI: 0.81–0.90). There was substantial heterogeneity between sites for all markers, but the two-step combination test performed well in Indonesia and Peru.\ud \ud Conclusion\ud Random plasma glucose followed by point-of-care HbA1c testing can accurately diagnose diabetes in tuberculosis patients, particularly those with substantial hyperglycaemia, while reducing the need for more expensive point-of-care HbA1c testing. Risk scores with or without biochemical data may be useful but require validation.
