Introduction Medical students experience higher rates of distress and burnout compared with their age-similar peers overall. Coaching has been proposed as one means of combating distress and burnout within the medical profession. The purpose of this systematic review is to synthesise the current evidence on the effects of coaching interventions on medical student well-being, including engagement, resilience, quality of life, professional fulfilment and meaning in work and distress, including burnout, anxiety and depressive symptoms. Methods and analysis We will conduct a systematic review of interventional and observational comparative studies that assess the effects of coaching interventions on well-being, including engagement, resilience, quality of life, professional fulfilment and meaning in work and distress, including burnout, anxiety and depressive symptoms among undergraduate medical students internationally. We will search PubMed (MEDLINE), Embase (OVID), PsycINFO (OVID), Scopus, ERIC, Cochrane Database of Systematic Reviews (OVID) and Cochrane Central Register of Controlled Trials (OVID) from their respective inception dates using the following search terms: (medical students OR medical student OR undergraduate medical education) AND (coach OR coaching OR coaches). Studies in any language will be eligible. Studies that report one or more outcomes of distress or well-being among medical students who receive a coaching intervention will be included. Data on participant and intervention characteristics, outcomes and instruments used will be collected as well as quality/risk of bias assessments. Two reviewers will screen studies against the inclusion criteria and perform data extraction. We will conduct a narrative synthesis, with meta-analysis if evidence permits quantitative pooling of results. Heterogeneity of results across studies according to study design, learner level and study risk of bias will be evaluated, as well as publication bias. Ethics and dissemination Ethical approval is not required for this review. Results will be disseminated by publication in a scientific journal. PROSPERO registration number CRD42022322503.

BACKGROUND Current consensus guidelines have discouraged the use of sub-0.5-cm (in situ) and sub-1-cm (invasive) margins when performing Mohs micrographic surgery (Mohs) for melanoma, with minimal evidence to guide this recommendation. OBJECTIVE To compare melanoma local recurrence rates after Mohs based on initial margin size. MATERIALS AND METHODS A systematic review and meta-analysis was conducted with search terms including Mohs micrographic surgery, surgical margin, recurrent disease, and melanoma. RESULTS Forty-three studies were included. The 5- to 10-mm margin category had a statistically significant lower local recurrence compared with 1- to 5-mm and 5-mm categories. Recurrence for 1- to 5-mm, 5-mm, 5- to 10-mm, and 10-mm categories were 2.3% (CI 0.8–3.5, p < .001), 1.4% (CI 0.6–2.2, p < .001), 0.3% (CI 0.2–0.5, p < .001), and 6.1% (CI -6.7 - 18.8, p = .349), respectively. Number of stages for 1 to 5, 5, 5 to 10, and 10-mm categories were 1.8, 1.8, 1.6, and 1.6, respectively. There was no statistically significant difference between the groups (p = .694). CONCLUSION Five- to 10-mm margins were associated with the lowest local recurrence rates. A 5- to 10-mm initial margin should be considered where other factors (tumor characteristics, anatomical or functional considerations) allow.

AbstractObjectivePrevious studies have suggested that patients with aspirin‐exacerbated respiratory disease (AERD) have a high likelihood of alcohol intolerance. The purpose of this systematic review is to identify if there is sufficient evidence to confirm this correlation and the impact of medical therapy on subsequent alcohol tolerance.Data SourcesPubMed, EMBASE, SCOPUS, EBSCO, Google Scholar, Cochrane Library, and Grey literature. We also performed snowballing on the identified observational studies (OS) for additional data.Review MethodsA systematic review was conducted from 1968 to 2022 to identify those studies describing AERD symptomatology triggered by alcohol intake. The primary outcome was to analyze the current literature for the association between alcohol intolerance and AERD symptoms. The secondary outcome looked for improvement in alcohol tolerance after aspirin desensitization or biological therapy.ResultsA total of 775 studies were identified and 40 abstracts were evaluated. From these, 5 studies met the inclusion criteria. Of the 5 manuscripts, there was 1 case‐control, 2 cohort, and 2 cross‐sectional studies. A total of 522 participants with AERD and a history of alcohol consumption were included, with 52.8% reporting at least 1 sinopulmonary exacerbation after alcohol intake. One of 3 studies noted improvement in alcohol tolerance after medical therapy with aspirin desensitization.ConclusionThe current literature suggests that patients with AERD have a high risk of alcohol intolerance. Additionally, aspirin desensitization may improve alcohol tolerance in this patient population.

ObjectiveUbiquitous throughout the literature and during patient counseling, vestibular schwannoma is often quoted to affect about 1 per 100,000 people. Yet, reports from distinct international populations suggest that the incidence is likely much higher. The objective of the current work was to systematically characterize the global incidence of sporadic vestibular schwannoma.Data SourcesScopus, Embase, and PubMed.Review MethodsPopulation‐based studies reporting incidence rates of sporadic vestibular schwannoma between January 2010 and August 2020 were searched with language restrictions requiring reports to be published in Chinese, English, German, Italian, or Spanish. The protocol was registered with PROSPERO (CRD42021228208) prior to commencement of data collection. PRISMA guidelines for transparent reporting of systematic reviews were followed.ResultsAmong 424 citations, 6 publications covering 4 distinct populations from Denmark, the Netherlands, Taiwan, and the United States met inclusion criteria. Most recent incidence rates of among all ages ranged between 3.0 and 5.2 per 100,000 person‐years. Highest incidence rates were reported among patients aged ≥70 years, peaking at 20.6 per 100,000 person‐years. One study from the United States reported the incidence of asymptomatic, incidentally diagnosed tumors at a rate of 1.3 per 100,000 person‐years from 2012 to 2016.ConclusionsRecent international incidence rates of sporadic vestibular schwannoma exceed the commonly quoted “1 per 100,000” figure by up to 5‐fold among all ages and by up to 20‐fold among age groups at highest risk. Based on modern incidence rates, the lifetime prevalence of developing sporadic vestibular schwannoma likely exceeds 1 per 500 persons.
