RESUMEN

TOPIC: This systematic review examined geographical and temporal trends in medical school ophthalmology education in relationship to course and student outcomes. CLINICAL RELEVANCE: Evidence suggesting a decline in ophthalmology teaching in medical schools is increasing, raising concern for the adequacy of eye knowledge across the rest of the medical profession. METHODS: Systematic review of Embase and SCOPUS, with inclusion of studies containing data on medical school ophthalmic course length; 1 or more outcome measures on student ophthalmology knowledge, skills, self-evaluation of knowledge or skills, or student course appraisal; or both. The systematic review was registered prospectively on the International Prospective Register of Systematic Reviews (identifier, CRD42022323865). Results were aggregated with outcome subgroup analysis and description in relationship to geographical and temporal trends. Descriptive statistics, including nonparametric correlations, were used to analyze data and trends. RESULTS: Systematic review yielded 4596 publication titles, of which 52 were included in the analysis, with data from 19 countries. Average course length ranged from 12.5 to 208.7 hours, with significant continental disparity among mean course lengths. Africa reported the longest average course length at 103.3 hours, and North America reported the shortest at 36.4 hours. On average, course lengths have been declining over the last 2 decades, from an average overall course length of 92.9 hours in the 2000s to 52.9 hours in the 2020s. Mean student self-evaluation of skills was 51.3%, and mean student self-evaluation of knowledge was 55.4%. Objective mean assessment mark of skills was 57.5% and that of knowledge was 71.7%, compared with an average pass mark of 66.7%. On average, 26.4% of students felt confident in their ophthalmology knowledge and 34.5% felt confident in their skills. DISCUSSION: Most evidence describes declining length of courses devoted to ophthalmology in the last 20 years, significant student dissatisfaction with courses and content, and suboptimal knowledge and confidence.

RESUMEN

BACKGROUND: Despite a high frequency of dermatological general practice and emergency department presentations, including serious and potentially fatal skin conditions, evidence suggests that undergraduate dermatological education remains sparse. Given this, there exists a need to gauge dermatology-relevant knowledge and skill in our new doctors. METHODS: An online survey was completed by final-phase medical students and junior doctors from Australian medical schools. The survey appraised self-perceived confidence of dermatology knowledge and skills, in addition to 5 knowledge-based multiple-choice questions. RESULTS: Nine hundred and forty-two eligible responses were completed. Respondents reported low confidence in identifying dermatological conditions in people with skin of colour (µ = 1.69), handing over to dermatology colleagues (µ = 2.00) and in diagnosing and managing acute/emergency dermatology conditions (µ = 1.84). In contrast, participants felt most confident in counselling sun-protective behaviours (µ = 3.95) and suturing small wounds (µ = 3.43). 76.4% of respondents had not undertaken any dermatology placement, and 70.9% had never been formally assessed in dermatology. Those who received dermatology placement had a significantly higher aggregated self-reported confidence (p < 0.0001) and answered significantly more MCQs correctly (p = 0.0419). Those who had been formally assessed had a significantly higher self-reported confidence (p < 0.001) and answered significantly more MCQs correctly (p = 0.007). CONCLUSION: Final-phase medical students and junior doctors exhibit low confidence across many dermatology competencies. Participants believed they need more dermatology education, and seldom feel prepared when exposed to dermatologic pathologies. Introduction of a standardised curriculum, formal assessments and increased clinical exposure are possible solutions.

RESUMEN

It is generally accepted that supported graphene is hydrophobic and that its water contact angle is similar to that of graphite. Here, we show that the water contact angles of freshly prepared supported graphene and graphite surfaces increase when they are exposed to ambient air. By using infrared spectroscopy and X-ray photoelectron spectroscopy we demonstrate that airborne hydrocarbons adsorb on graphitic surfaces, and that a concurrent decrease in the water contact angle occurs when these contaminants are partially removed by both thermal annealing and controlled ultraviolet-O3 treatment. Our findings indicate that graphitic surfaces are more hydrophilic than previously believed, and suggest that previously reported data on the wettability of graphitic surfaces may have been affected by unintentional hydrocarbon contamination from ambient air.

RESUMEN

Evolving evidence suggests that Janus Kinase Inhibitors (JAKi) may predispose to certain infections, including tuberculosis and human herpes viruses. This review aimed to compare the infection risk in patients on a systemic JAKi for a dermatologic indication to a placebo. A systematic review was carried out from inception to June 2023, using the EMBASE, Medline, SCOPUS, and Cochrane Library of Registered Trials databases. Eligible studies included placebo-controlled randomized trials that investigated the incidence of infection in patients with a dermatologic indication. Primary outcomes included the most commonly reported infections pertaining to serious and opportunistic infections, upper respiratory tract infections, nasopharyngitis, herpes simplex, varicella zoster, tuberculosis, neutropenia, and lymphopenia. A meta-analysis of incidence ratios was conducted to determine odds ratios (OR), with a 95% confidence interval (CI) analysis. The meta-analysis found no increased risk of serious (OR: 0.92, 95% CI: 0.61-1.43, P = 0.74) or opportunistic infections (OR: 0.65, 95% CI: 0.32-1.31, P = 0.23). The incidence of varicella-zoster infections was significantly higher in the JAKi cohort (OR: 1.72, 95% CI: 1.08-2.72, P = 0.022). From 25 studies, there was no overall increased risk of herpes simplex infections (OR: 1.43, 95% CI: 0.93-2.23, P = 0.102) to placebo; however, a significantly higher risk in those with atopic dermatitis to alopecia areata was demonstrated (OR: 1.73, 95% CI: 1.13-2.69, P = 0.013). The results of this analysis do not suggest an increased risk of serious and opportunistic infections in those on JAKi compared to placebo. However, they support an increased risk of varicella-zoster infections and a higher risk of herpes simplex infections in those with atopic dermatitis to alopecia areata. The results of this report support these agents' short-term safety but signal that vigilance should be practiced in patients at risk for serious or recurrent herpes virus infections.

RESUMEN

INTRODUCTION: Many patients undergoing cutaneous surgery are prescribed at least one anticoagulant or antiplatelet agent. With the recent emergence of direct oral anticoagulants (DOACs), there is a deficit of knowledge regarding optimal perioperative management. This review aims to evaluate the evidence and risk surrounding management of DOACs in patients undergoing skin surgeries. METHODS: Systematic review of EMBASE, Scopus, and PubMed, with inclusion of studies that detailed perioperative management of DOACs in those undergoing skin surgery. Primary outcome measures were perioperative hemorrhagic and thromboembolic complications. RESULTS: Seven thousand seven hundred and forty-one abstracts were identified, with 13 articles meeting inclusion criteria. Two studies investigated complication risk associated with DOAC continuation in skin surgery and found an average rate of hemorrhagic complications of 1.74%. Two studies evaluated complications associated with DOAC cessation prior to skin surgery, with a pooled thromboembolic complication rate of 0.15%. Articles comparing continuation and cessation discovered no decreased risk of bleeding with DOAC cessation prior to surgery (P = 0.93). Seven of the 13 articles compared complications in a control vs a DOAC group undergoing cutaneous procedures. Evidence was conflicting but may have suggested a small increase in bleeding risk in those on DOAC therapy. CONCLUSION: Optimal management of anticoagulants perioperatively is difficult because of conflicting information, complicated by advent of novel agents. Risk of hemorrhagic complications with both continuation and interruption of DOAC therapy was low. Perioperative DOAC management can be guided by procedural bleeding and patient clotting risk and can often be continued in minor dermatologic procedures.

RESUMEN

Importance: Evolving evidence suggests that patients receiving Janus kinase-signal transducer and activator of transcription inhibitors (JAK-STATi) may be at higher risk of major adverse cardiovascular events (MACE) and venous thromboembolism (VTE). Most existing literature has focused on indications that may confer a higher MACE and VTE risk than that among patients with isolated dermatological indications. Objective: To evaluate risk of MACE, VTE, serious adverse events (SAEs), and tolerability of systemic JAK-STATi compared with placebo, in those with a dermatologic indication. Data Sources: A systematic review of the literature was carried out to June 2023, using databases Embase, MEDLINE, SCOPUS, Cochrane Library of Registered Trials, and registered Clinical Trials. The analysis was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. The analysis itself took place in June 2023. Study Selection: Placebo-controlled randomized clinical trials that compared systemic JAK-STATi with placebo, and investigated the safety in patients with alopecia areata, psoriasis, vitiligo, atopic dermatitis, lichen planus or hidradenitis suppurativa. Data Extraction and Synthesis: Study selection and data extraction by 2 authors working independently using a standardized template. Crude numbers for MACE, VTE, SAEs, and study discontinuation due to treatment emergent adverse events (TEAEs) were pooled and underwent meta-analysis. Main Outcomes and Measures: Incidence of MACE, VTE, SAE, and study discontinuation due to TEAEs. Analysis of these values against person exposure years to determine the incidence rate (IR). Risk ratios (RRs) compared incidence rates among treatment and placebo comparator arms. Results: Forty-five randomized clinical trials were eligible for inclusion, with 12 996 patients receiving active JAK-STATi therapy and 4925 allocated to placebo treatment. Meta-analysis found no significant increase in MACE (I2 = 0.00%; RR, 0.47; 95% CI, 0.28-0.80) or VTE (I2 = 0.00%; RR, 0.46; 95% CI, 0.26-0.80) between placebo and JAK-STATi comparator arms. There was also no significant difference in SAEs (I2 = 12.38%; RR, 0.92; 95% CI, 0.72-1.20) and discontinuations between JAK-STATi and placebo (I2 = 23.55%; RR, 0.94; 95% CI, 0.76-1.19). Conclusions and Relevance: This meta-analysis did not identify a significant increase in the risk of MACE and VTE in dermatology patients receiving JAK-STATi for median duration of 16 weeks. The results of this review suggest there is insufficient evidence that JAK-STATi confer an increased risk of cardiovascular complications in dermatological patients, especially when used for short time frames.
