RESUMO
BACKGROUND: Melanoma is the 5th commonest cancer in the UK and survivors require frequent and thorough skin checks. During the Achieving Self-directed Integrated Cancer Aftercare (ASICA) trial, melanoma survivors used an app to submit images of concerning lesions for assessment by a dermatology nurse. In the past, online courses have been used to train non-specialist primary care practitioners (PCPs) in this skill. OBJECTIVES: This study aimed to determine whether an online course could increase knowledge, confidence, and attitudes towards skin image triage in PCPs in the Grampian area. METHODS: Preliminary discussions were held with PCPs to determine the need for an online course. The course was designed at the University of Aberdeen and included an introduction to the skin, case studies and quizzes on a variety of skin conditions based on melanoma survivors' submissions via the ASICA app. Two pre- and post-course questionnaires were administered to all participants to (1) assess knowledge gained and (2) assess any improvements in confidence and attitudes towards triaging skin lesions that could be indicative of skin cancer. All PCPs in the Grampian area were invited to participate with almost 70 medical practices contacted. Results were analysed using a paired sample T-test. RESULTS: The course was advertised to all GP practices in the Grampian area and 38 PCPs completed all its stages. Undertaking the course improved all PCPs' confidence and attitudes towards triaging (p < 0.001). It also improved knowledge in all non-GP PCPs (p = 0.01). Most participants found the course useful; thought it was at the right level of difficulty, right format and thought the design was good. CONCLUSIONS: Our online course in triaging skin lesions submitted digitally to PCPs was able to improve knowledge, confidence, and attitudes towards triaging. The course was acceptable in its design and was deemed useful and applicable to practice. Further research should investigate the effect the course has on secondary care referral numbers.

We developed the Achieving Self-directed Integrated Cancer Aftercare (ASICA) in melanoma app to support monthly total-skin self-examinations (TSSE) by people previously treated for melanoma. A randomized 12-month trial demonstrated ASICA supported optimal monthly TSSE adherence in a third of participants (ClinicalTrials.gov NCT03328247). However, a further third of participants adhered well initially but subsequently dropped off, and a final third did not adhere at all. This follow-up qualitative study investigated trial participants' perceptions of barriers and facilitators to TSSE adherence using the app. Three former trial participants participated in a single focus group and 11 participated in new semistructured telephone interviews. These were analysed thematically alongside secondary analysis of 13 qualitative interviews conducted during the trial. All transcripts were recorded, transcribed and analysed thematically. Five themes encompassing barriers and facilitators to ASICA adherence emerged. These were: technology, role of others, tailoring, disease journey and competing priorities. These data will inform further development of ASICA to increase user adherence.

BACKGROUND: Melanoma is a relatively common cancer type with a high survival rate, but survivors risk recurrences or second primaries. Consequently, patients receive regular hospital follow-up, but this can be burdensome to attend and not optimally timed to detect arising problems. Total skin self-examination (TSSE) supports improved clinical outcomes from melanoma via earlier detection of recurrences and second primaries, and digital technology has the potential to support TSSE. Recent research with app-based interventions aimed at improving the well-being of older adults has found that they can use the technology and benefit from it, supporting the use of digital health care in diverse demographic groups. Thus, the Achieving Self-directed Integrated Cancer Aftercare (ASICA) digital health care intervention was developed. The intervention provided melanoma survivors with a monthly prompt to perform a TSSE as well as access to a dermatology nurse who provided them with feedback on photographs and descriptions of their skin. OBJECTIVE: We aimed to explore participants' attitudes, beliefs, and experiences regarding TSSE practices. Furthermore, we explored how participants experienced technology and how it influenced their practice of TSSE. Finally, we explored the practical and technical experiences of ASICA users. METHODS: This was a nested qualitative evaluation within a dual-center randomized controlled trial of the ASICA intervention. We conducted semistructured telephone interviews with the participants during a randomized controlled trial. The participants were purposively sampled to achieve a representative sample with representative proportions by age, sex, and residential geography. Interviews were transcribed verbatim and analyzed using a framework analysis approach applied within NVivo 12. RESULTS: A total of 22 interviews were conducted with participants from both groups. In total, 40% (9/22) of the interviewed participants were from rural areas, and 60% (13/22) were from urban areas; 60% (13/22) were from the intervention group, and 40% (9/22) were from the control group. Themes evolved around skin-checking behavior, other people's input into skin checking, contribution of health care professionals outside ASICA and its value, ideas around technology, practical experiences, and potential improvements. ASICA appeared to change participants' perceptions of skin checking. Users were more likely to report routinely performing TSSE thoroughly. There was some variation in beliefs about skin checking and using technology for health care. Overall, ASICA was experienced positively by participants. Several practical suggestions were made for the improvement of ASICA. CONCLUSIONS: The ASICA intervention appeared to have positively influenced the attitudes and TSSE practices of melanoma survivors. This study provides important qualitative information about how a digital health care intervention is an effective means of prompting, recording, and responding to structured TSSE by melanoma survivors. Technical improvements are required, but the app offers promise for technologically enhanced melanoma follow-up in future.

BACKGROUND: Inorganic nitrate, abundant in leafy green vegetables and beetroot, is thought to have protective health benefits. Adherence to a Mediterranean diet reduces the incidence and severity of coronary artery disease, whereas supplementation with nitrate can improve submaximal exercise performance. Once ingested, oral commensal bacteria may reduce nitrate to nitrite, which may subsequently be reduced to nitric oxide during conditions of hypoxia and in the presence of "nitrite reductases" such as heme- and molybdenum-containing enzymes. OBJECTIVE: We aimed to explore the putative effects of inorganic nitrate and nitrite on mitochondrial function in skeletal muscle. METHODS: Mice were subjected to a nitrate/nitrite-depleted diet for 2 wk, then supplemented with sodium nitrate, sodium nitrite, or sodium chloride (1 g/L) in drinking water ad libitum for 7 d before killing. Skeletal muscle mitochondrial function and expression of uncoupling protein (UCP) 3, ADP/ATP carrier protein (AAC) 1 and AAC2, and pyruvate dehydrogenase (PDH) were assessed by respirometry and Western blotting. Studies were also undertaken in human skeletal muscle biopsies from a cohort of coronary artery bypass graft patients treated with either sodium nitrite (30-min infusion of 10 µmol/min) or vehicle [0.9% (wt:vol) saline] 24 h before surgery. RESULTS: Neither sodium nitrate nor sodium nitrite supplementation altered mitochondrial coupling efficiency in murine skeletal muscle, and expression of UCP3, AAC1, or AAC2, and PDH phosphorylation status did not differ between the nitrite and saline groups. Similar results were observed in human samples. CONCLUSIONS: Sodium nitrite failed to improve mitochondrial metabolic efficiency, rendering this mechanism implausible for the purported exercise benefits of dietary nitrate supplementation. This trial was registered at clinicaltrials.gov as NCT04001283.

BACKGROUND: Being overweight or obese following breast cancer diagnosis can increase cancer recurrence and mortality, so effective interventions for weight loss in this group could enhance survival. A pilot randomised controlled trial was conducted to assess whether a weight loss programme comprising generic Weight Watchers® referral offered to women treated for breast cancer with or without additional breast cancer-tailored dietetic support is feasible and shows promise for improving weight and quality of life (QoL). METHODS: Participants were randomly allocated to 3 groups: Weight Watchers® referral (for 12 sessions of meetings and digital tools) plus 5 breast cancer-tailored dietitian-led group support sessions (WW Plus: n = 14), Weight Watchers® referral only (WW: n = 16) or control (Weight Watchers® referral after 3 months, n = 15). Feasibility was assessed based on retention rate, recruitment and randomisation process, meeting attendance, suitability of the setting and outcome measurement tools, unintended consequences, cost and observations of the dietetic sessions. Outcomes were measured at 0, 3 ('trial exit') and 12 months post intervention. RESULTS: The response rate to the invitation was 43% (140/327) of whom 58 were eligible and 45 (median age 61.0 years; body mass index 30.2 kg/m2) were randomised. Data from 38 (84%) and 30 (67%) participants were available at trial exit and 12 months respectively. Feasibility issues included slow recruitment process, lack of blinding throughout, weighing scales not measuring > 150 kg, lack of clear instructions for completing QoL questionnaire and workload and time pressures in delivering dietetic sessions. Participants had good attendance rate at group meetings and no serious unintended consequences were reported. WW Plus was most expensive to run. Mean (95% CI) weight change at trial exit was - 3.67 kg (- 5.67, - 2.07) in WW Plus, - 6.03 kg (- 7.61, - 4.44) in WW group and + 0.19 kg (- 1.45, + 1.83) in control group. About 40% of the WW Plus, 64% of the WW group and 56% of the control group lost ≥ 5% of their baseline weight by 12 months. All groups showed promise for improving QoL at trial exit but only the WW group maintained significant improvements from baseline at 12 months. CONCLUSIONS: The trial procedures were feasible, with some modifications. This pilot trial indicates the benefits of providing free WW vouchers for weight loss maintenance and improving QoL but provided no evidence that including additional dietetic support would add any extra value. Further research with WW with long-term follow-up should be undertaken to assess weight loss sustainability and benefit on health outcomes in this patient group. TRIAL REGISTRATION: ISRCTN-29623418.
RESUMO
BACKGROUND: Lateral ankle sprains can lead to persistent disability in athletes. The authors studied the effect of a lateral ankle sprain on reinjury occurrence in the same region. HYPOTHESIS: There will be no difference in reinjury rate between low-grade (grades I and II) and high-grade (IIIA and IIIB) acute lateral ankle sprains. STUDY DESIGN: Cohort study (prognosis); Level of evidence, 1. METHODS: From 1996 to 2004, the authors managed 202 elite Greek track and field athletes for an acute lateral ankle sprain. Sprains were classified into 4 degrees (I, II, IIIA, and IIIB). The same rehabilitation protocol was prescribed for all the athletes. The rate of a lateral ankle reinjury was recorded in the 24 months following injury. RESULTS: At a follow-up of 24 months, 36 of 202 athletes (17.8%) experienced a second lateral ankle sprain. Of the 79 athletes with a grade I injury, 11 (14%) experienced a recurrence during the study period. Of the 81 athletes with a grade II injury, 23 (29%) experienced a recurrence during the study period. Of the 36 athletes with a grade IIIA injury, 2 (5.6%) experienced a recurrence during the study period. Of the 6 athletes with a grade IIIB injury, none experienced a recurrence during the study period. CONCLUSION: Athletes with a grade I or II lateral ankle sprain are at higher risk of experiencing a reinjury. Low-grade acute lateral ankle sprains result in a higher risk of reinjury than high-grade acute lateral ankle sprains.
