ABSTRACT

PURPOSE: Appropriate surveillance of patients with melanoma treated with curative intent is vital to improve patient outcomes. A systematic review was conducted to capture locoregional recurrence and metastatic disease, and to evaluate the effectiveness of various surveillance strategies. METHODS: MEDLINE, EMBASE, PubMed, Cochrane Database of Systematic Reviews, and National Cancer Institute Clinical Trials Database were searched. Randomized controlled trials (RCTs) and comparative studies reporting at least one patient-related outcome were included. Exclusion criteria included: published in non-English or recruited >20 % or an uncertain percentage of non-target patients without conducting a subgroup analysis for the target patients. This review was registered at PROSPERO (CRD42021246482). RESULTS: Among 17,978 publications from the literature search, one RCT and five non-randomized comparative studies were included and comprised 4016 patients. The aggregate evidence certainty was low for the RCT and very low for the comparative studies, as assessed by the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. For patients with stage IA-IIC melanoma, a reduced follow-up schedule with clinical follow-up strategies alone may be safe and cost-effective. For stage IIC-IIIC patients, at least two serial PET/CT or whole-body CT and brain MRI imaging within a median follow-up of 31.2 months may detect 50 % of recurrences that lead to additional management, such as surgery. PET/CT may have a higher positive predictive value and lower false positive rate compared with CT alone in detecting recurrence in stage I-III patients. CONCLUSION: Surveillance protocols should be based on individual risk of recurrence and established best practices when formulating follow-up strategies, as suggested by the studies reviewed. Future high-quality studies are needed to clarify the frequency of imaging follow-up strategies, especially in patients with high-risk stage II melanoma.

ABSTRACT

OBJECTIVE: Although patient outcomes in psoriatic arthritis (PsA) have improved with the advent of advanced therapies, there remains a high unmet need to treat residual disease activity. The objective of the current study was to quantify residual disease activity and burden of disease in Canadian patients with PsA. METHODS: This was a multiregion, observational, retrospective analysis of patient data extracted from the Rhumadata and the International Psoriasis and Arthritis Research Team (IPART) registries, analyzing deidentified data from patients who had initiated advanced therapy for the treatment of PsA between January 2010 and December 2019. The primary endpoint was the proportion of patients failing to achieve minimal disease activity (MDA) within 6 months; secondary endpoints included clinical and patient-reported burden of disease. Descriptive statistics included summaries by region, treatment class, and number of prior advanced therapies. RESULTS: One thousand five hundred ninety-six patients were included. The proportions of patients who failed to achieve MDA within 6 months of an advanced therapy were 64.8% in Ontario, 68.3% in Western Canada, 74.8% in Quebec, and 75% in the Atlantic/East region. Failure to achieve MDA was higher among patients receiving an IL-17i compared with a TNFi in all regions except the Atlantic/East. Between 73.2% and 78.6% of patients reported pain at 6 months, and continuing functional impairment varied from 24% in the West to 83.3% in the Atlantic/East. CONCLUSION: There is substantial burden and unmet need for improved therapies for Canadians with PsA. There is a wide regional variation in outcomes that requires further assessment.

ABSTRACT

OBJECTIVE: This study aimed to explore the experiences of dermatologists and rheumatologists in the early recognition of psoriatic arthritis (PsA) and to identify potential improvements to the current shared-care model. METHODS: A 24-question survey addressing referral strategies was constructed by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) project steering committee and sent to all members (n = 927). Questions addressed the use of screening tools, frequency of PsA in patients with psoriasis, therapeutic decision making, and suggestions for earlier PsA recognition and current unmet needs. RESULTS: There were 149 respondents (16.1% response rate), which included 113 rheumatologists from 37 countries and 26 dermatologists from 16 countries. Of the dermatologists, 81% use PsA-specific screening instruments. Conversely, rheumatologists reported that only 26.8% of patients referred to them from all sources had been assessed with screening tools. Although dermatologists reported that a mean of 67% of suspected PsA cases were confirmed, rheumatologists reported a mean of 47.9% of confirmed cases. Both specialties reported similar views regarding optimization of the diagnostic process and indicated that the best approach involved combining patient-reported (ie, screening tools) and physician-confirmed findings. Moreover, both specialties identified the education of primary care physicians (PCPs) and dermatologists as the greatest priority to improve PsA screening. CONCLUSION: The survey indicated the current unmet needs in the early recognition of PsA. Important areas to address include improving the use of screening instruments, increasing the education of community-based dermatologists and PCPs, and using a combination of patient-reported and physician-confirmed findings in the screening approach.

ABSTRACT

OBJECTIVE: A simple, scalable tool that identifies psoriasis patients at high risk for developing psoriatic arthritis (PsA) could improve early diagnosis. We aimed to develop a risk prediction model for the development of PsA and to assess its performance among patients with psoriasis. METHODS: We analyzed data from a prospective cohort of psoriasis patients without PsA at enrollment. Participants were assessed annually by a rheumatologist for the development of PsA. Information about their demographics, psoriasis characteristics, comorbidities, medications, and musculoskeletal symptoms was used to develop prediction models for PsA. Penalized binary regression models were used for variable selection while adjusting for psoriasis duration. Risks of developing PsA over 1- and 5-year time periods were estimated. Model performance was assessed by the area under the curve (AUC) and calibration plots. RESULTS: Among 635 psoriasis patients, 51 and 71 developed PsA during the 1-year and 5-year follow-up periods, respectively. The risk of developing PsA within 1 year was associated with younger age, male sex, family history of psoriasis, back stiffness, nail pitting, joint stiffness, use of biologic medications, patient global health, and pain severity (AUC 72.3). The risk of developing PsA within 5 years was associated with morning stiffness, psoriatic nail lesion, psoriasis severity, fatigue, pain, and use of systemic nonbiologic medication or phototherapy (AUC 74.9). Calibration plots showed reasonable agreement between predicted and observed probabilities. CONCLUSIONS: The development of PsA within clinically meaningful time frames can be predicted with reasonable accuracy for psoriasis patients using readily available clinical variables.

ABSTRACT

People with psoriasis (PsO) are at increased risk of developing psoriatic arthritis (PsA). Screening patients with PsO for PsA may be helpful in diagnosing PsA early. Dermatologists play a role in assessing their patients with PsO for musculoskeletal symptoms and referring them to a rheumatologist for diagnosis and treatment.

ABSTRACT

Photoprotection is a critical health prevention strategy to reduce the deleterious effects of ultraviolet radiation (UVR) and visible light (VL). Methods of photoprotection are reviewed in this paper, with an emphasis on sunscreen. The most appropriate sunscreen formulation for personal use depends on several factors. Active sunscreen ingredients vary in their protective effect over the UVR and VL spectrum. There are dermatologic diseases that cause photosensitivity or that are aggravated by a particular action spectrum. In these situations, sunscreen suggestions can address the specific concern. Sunscreen does not represent a single entity. Appropriate personalized sunscreen selection is critical to improve compliance and clinical outcomes. Health care providers can facilitate informed product selection with awareness of evolving sunscreen formulations and counseling patients on appropriate use. This review aims to summarize different forms of photoprotection, discuss absorption of sunscreen ingredients, possible adverse effects, and disease-specific preferences for chemical, physical or oral agents that may decrease UVR and VL harmful effects.

ABSTRACT

OBJECTIVE: Nail psoriasis is common, impairs fine motor finger functioning, affects cosmesis, and is associated with a lower quality of life. This review updates the previous Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations for nail psoriasis. METHODS: This systematic literature review of the PubMed, MEDLINE, Embase, and Cochrane databases examined the updated evidence since the last GRAPPA nail psoriasis treatment recommendations published in 2014. Recommendations are based on preformed PICO (Patient/Population - Intervention - Comparison/Comparator - Outcome) questions formulated by an international group of dermatologists, rheumatologists, and patient panel members. Data from this literature review were evaluated in line with Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. RESULTS: Overall, there is insufficient evidence to make any recommendation for the use of topical corticosteroids, topical calcipotriol, topical tazarotene, topical cyclosporine, dimethyl fumarates/fumaric acid esters, phototherapy, and alitretinoin. There is a low strength of evidence to support the use of calcipotriol and corticosteroid preparations, topical tacrolimus, oral cyclosporine, oral methotrexate, intralesional corticosteroids, pulsed dye laser, acitretin, Janus kinase inhibitors, and apremilast. CONCLUSION: The highest strength of supporting evidence is for the recommendation of biologic agents including tumor necrosis factor inhibitors, and interleukin 12/23, 17, and 23 inhibitors.

ABSTRACT

Each year, the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) holds a trainee symposium adjacent to the GRAPPA annual meeting. The target audience for this meeting includes trainees in rheumatology, dermatology, and related fields. The 2021 GRAPPA Trainee Symposium focused on challenges in the diagnosis and assessment of psoriatic arthritis (PsA). During the meeting, speakers focused on identification of psoriasis (PsO), the differential diagnosis for both PsO and PsA, diagnostic errors and pitfalls, physical examination in PsA, patient-reported outcomes and composite measures in the assessment of PsA, and the patient perspective on diagnosis and assessment, followed by a panel discussion. This paper summarizes the content discussed at the meeting.

ABSTRACT

OBJECTIVE: To assess the correlation between cannabis use and psoriatic disease severity, health-related quality of life, pain, psychosocial outcomes, and cytokine levels in psoriasis (PsC) and psoriatic arthritis (PsA) patients. METHODS: PsC and PsA patients enrolled in the International Psoriasis and Arthritis Research Team (IPART) program were surveyed on cannabis use and were asked to provide a serum and urine sample. Demographic and clinical variables were compared between users and non-users using Student's t-test or Mann-Whitney U test for continuous variables, and chi-square or Fisher's exact test for categorical variables. RESULTS: Of 151 respondents, 30% reported current cannabis use within the last year. Compared to non-users, cannabis users were younger and had a shorter PsA duration and poorer mental health as measured by the SF-36. Other measures of health-related quality of life and pain were comparable between the groups. Respondents' primary perceived benefits of cannabis use were aid in sleep and arthritis pain relief, but there was no difference in pain between users and non-users. No THC was detected in the urine of non-users while users had a mean level of 19.6 ng/ml. Serum IL-23 levels were statistically significantly higher in non-users than in users. CONCLUSION: A third of the patients used cannabis within the past year, and 54.3% of users reported the use of cannabis for arthritis pain relief. However, there was no difference in pain scores. Comprehensive education for providers on the current body of evidence and further studies on cannabis use and outcomes in psoriatic disease are needed. Key Points • A third of patients with psoriatic arthritis have used cannabis in the past year. • Most used it for better sleep and control of pain. • There was no difference in pain scores between users and non-users. • IL-23 levels were significantly higher in non-users.

ABSTRACT

This study explores female indoor tanners' perceptions of the current, text-only Canadian health warning label (HWL) for tanning equipment, as well as pictorial, evidence-based alternative HWLs. We created 10 test HWLs that depicted skin health effects, eye damage, premature aging, and death. Young women who had tanned indoors in the past year discussed these and the current federal HWL in focus groups. Although the current Canadian HWL was seen as informative, several participants did not recognize it, and many said that they would not read it due to the small text, wordiness, and lack of an image. Graphic images, particularly those depicting permanent conditions affecting the face, eyes, or appearance, were seen as effective. Common criticisms of the images were lack of believability, relatability, and comprehensibility. Although concise text was important for encouraging reading, many participants expressed a desire for more information in the test HWLs. Premature aging was of great concern to many participants, but the images selected for these HWLs were not perceived as effective. Although the text was seen as effective in the death HWLs, most participants dismissed the images. This research has implications for IT HWLs in Canada and globally. These results suggest that graphic images may be impactful in IT HWLs. Images must be supplemented with informative text that increases believability, relatability, and comprehensibility. These modifications would create HWLs that are engaging, informative, and that form part of a wider effort to spread awareness about the harmful effects of IT.

ABSTRACT

BACKGROUND: Psoriasis is a chronic inflammatory disease affecting multiple organ systems and resulting in reduced quality of life for many patients. A screening tool would be useful, particularly in underserviced or research settings with limited access to dermatologists. The Toronto Psoriatic Arthritis Screen, version 2 (ToPAS 2) is a validated screening tool for psoriatic arthritis containing questions specific for psoriasis. OBJECTIVES: To evaluate the performance of skin-specific questions from ToPAS 2 for the diagnosis of psoriasis. METHODS: Participants aged >18 were recruited from Dermatology and Family Medicine clinics and completed the ToPAS 2 questionnaire prior to being examined by a dermatologist for psoriasis. Two scoring indexes were derived from the ToPAS 2 skin-related questions using backward selection regression models. Statistical analysis was performed using receiver operating characteristic (ROC) curves to measure their performances. RESULTS: Two hundred and fifty eight participants were recruited. 32 (12%) were diagnosed with psoriasis by dermatologist assessment. Index 1 includes all 5 skin-related questions from ToPAS 2, while Index 2 includes three of the five questions. Both indexes demonstrate high specificity (82% to 92%), sensitivity (69% to 84%), and excellent negative predictive value (NPV) (>95%) for a diagnosis of psoriasis. The overall discriminatory power of these models is 0.823 (Index 1) and 0.875 (Index 2). CONCLUSIONS: Skin-related questions from ToPAS 2 have discriminatory value in detecting psoriasis, specifically questions relating to a family history, a prior physician diagnosis of psoriasis or a rash consistent with images of plaque psoriasis. This study is a valuable step in developing a screening tool for psoriasis.

ABSTRACT

BACKGROUND: Re-excision due to positive margins following breast-conserving surgery (BCS) negatively affects patient outcomes and healthcare costs. The inability to visualize margin involvement is a significant challenge in BCS. 5-Aminolevulinic acid hydrochloride (5-ALA HCl), a non-fluorescent oral prodrug, causes intracellular accumulation of fluorescent porphyrins in cancer cells. This single-center Phase II randomized controlled trial evaluated the safety, feasibility, and diagnostic accuracy of a prototype handheld fluorescence imaging device plus 5-ALA for intraoperative visualization of invasive breast carcinomas during BCS. METHODS: Fifty-four patients were enrolled and randomized to receive no 5-ALA or oral 5-ALA HCl (15 or 30 mg/kg). Forty-five patients (n = 15/group) were included in the analysis. Fluorescence imaging of the excised surgical specimen was performed, and biopsies were collected from within and outside the clinically demarcated tumor border of the gross specimen for blinded histopathology. RESULTS: In the absence of 5-ALA, tissue autofluorescence imaging lacked tumor-specific fluorescent contrast. Both 5-ALA doses caused bright red tumor fluorescence, with improved visualization of tumor contrasted against normal tissue autofluorescence. In the 15 mg/kg 5-ALA group, the positive predictive value (PPV) for detecting breast cancer inside and outside the grossly demarcated tumor border was 100.0% and 55.6%, respectively. In the 30 mg/kg 5-ALA group, the PPV was 100.0% and 50.0% inside and outside the demarcated tumor border, respectively. No adverse events were observed, and clinical feasibility of this imaging device-5-ALA combination approach was confirmed. CONCLUSIONS: This is the first known clinical report of visualization of 5-ALA-induced fluorescence in invasive breast carcinoma using a real-time handheld intraoperative fluorescence imaging device. TRIAL REGISTRATION: Clinicaltrials.gov identifier NCT01837225 . Registered 23 April 2013.

ABSTRACT

College and university students are a group known for excessive sun exposure and indoor tanning. Health education campaigns for avoidance of ultraviolet (UV) radiation have been relatively unsuccessful in this population. This systematic review examines interventions aimed at post-secondary school young adults on college and university campuses for skin cancer awareness, photoprotection, and change in UV-exposure-related behavior. Fifty-nine studies were identified for inclusion according to predetermined criteria. Study heterogeneity was high; methods of intervention were individual or group-based, and were mostly visually delivered and/or passive learning. Most interventions occurred at a single time point. Intervention success was assessed by evaluating subject behavior, intention, attitudes, knowledge, and emotion. Multicomponent interventions, generally consisting of UV photography and a passively delivered educational component, may be more effective than a single component alone. Overall, study quality was poor. Sample size of the majority of studies was <150 subjects. Most studies used self-report of behavior and had a short follow-up time. Generalizability of findings may be impacted as women, particularly white/Caucasian women, were overrepresented in the studies identified by this systematic review. For this specific target population, themes arising from the review include the importance of self-relevance and message framing. Self-affirmation was identified as a potential challenge in designing interventions for this target group, which can lead to defensiveness and a negative reaction to the health message. The findings of this systematic review may inform future research in this field, as well as guide planning of effective interventions in this target population.

ABSTRACT

The concept of psoriatic arthritis (PsA) prevention is gaining increased interest owing to the physical limitation, poor quality of life and low remission rates that are achieved with current therapies for PsA. The psoriasis-to-PsA transition offers a unique opportunity to identify individuals at increased risk of developing PsA and to implement preventive strategies. However, identifying individuals at increased risk of developing PsA is challenging as there is no consensus on how this population should be defined. This Consensus Statement puts forward recommended terminology from the Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network (PPACMAN) for defining specific subgroups of individuals during the preclinical and early clinical phases of PsA to be used in research studies. Following a three-round Delphi process, consensus was reached for three terms and definitions: 'increased risk for PsA', 'psoriasis with asymptomatic synovio-entheseal imaging abnormalities' and 'psoriasis with musculoskeletal symptoms not explained by other diagnosis'. These terms and their definitions will enable improved identification and standardization of study populations in clinical research. In the future, as increasing evidence emerges regarding the molecular and clinical features of the psoriasis-to-PsA continuum, these terms and definitions will be further refined and updated.

ABSTRACT

OBJECTIVE: Information about the prediagnosis period in psoriatic arthritis (PsA) is limited. The present study was undertaken to compare health care utilization related to musculoskeletal issues during a 5-year period prior to the diagnosis of PsA versus that of subjects with no prior inflammatory arthritis within a primary care setting. METHODS: We conducted a population-based, matched cohort study using electronic medical records and administrative data in Ontario, Canada. Age- and sex-matched cohorts of PsA patients and comparators from the same family physicians were assembled. Comparators were not allowed to have prior spondyloarthritis, ankylosing spondylitis, or rheumatoid arthritis billing code diagnoses. The study outcomes included health care utilization and costs related to nonspecific musculoskeletal issues during a 5-year period prior to the index date. RESULTS: We studied 462 PsA patients and 2,310 matched comparators. The odds ratio (OR) related to visiting a primary care physician for nonspecific musculoskeletal issues in patients with PsA was 2.14 (95% confidence interval 1.73-2.64) in the year immediately preceding the index date and was similarly elevated up to 5 years prior. The OR related to using other musculoskeletal-related health care services, including musculoskeletal specialists visits, joint injections, joint imaging, and emergency department visits, was higher in PsA as early as 5 years preceding the index date. Total and musculoskeletal-related health care costs prior to the index date were higher for patients with PsA versus comparators. CONCLUSION: A prodromal PsA phase characterized by nonspecific musculoskeletal symptoms may exist. Further study is needed to determine if this represents a window for earlier diagnosis of PsA.

ABSTRACT

BACKGROUND: There is limited information about mortality rates among patients with psoriasis and psoriatic arthritis (PsA) in North America and their change over the past 2 decades. OBJECTIVE: To compare all-cause and cause-specific mortality rates in patients with psoriasis to the general population in Ontario, Canada, from 1996 to 2016. METHODS: We conducted a population-based, retrospective cohort study of adult residents using administrative health data. All-cause and cause-specific standardized mortality rates, standardized mortality ratios, and excess mortality rates were calculated. RESULTS: 176,858 (2,524 deaths) patients with psoriasis and 15,430 (221 deaths) patients with PsA were identified in 2016. Patients with psoriasis and PsA had standardized excess mortality rates of 1.44 and 2.43 per 1000 population, respectively. Standardized mortality rates decreased by approximately 30% over the study period in both disease groups but remained significantly elevated compared to the general population. The leading causes of death in psoriasis and PsA patients were cancer, circulatory disease, and respiratory conditions. LIMITATIONS: We were unable to classify patients according to disease severity. CONCLUSIONS: Despite improvements in psoriasis treatment, the relative excess mortality, which may be related to risk factors for psoriatic disease, remained unchanged, with an average of approximately 1 to 2 extra deaths per 1,000 patients in 2016.

ABSTRACT

As part of an in-depth review of the specialty for the Royal College of Physicians and Surgeons of Canada (RCPSC), the Dermatology Working Group (DWG) was tasked with leading a comprehensive and objective analysis of the current state of Dermatology practice and training patterns in Canada. Preliminary research for the report was conducted in 3 areas: a jurisdictional analysis, a literature review, and a landscape overview. The results of this research were published in the spring 2019 edition of the Journal of Cutaneous Medicine and Surgery. Various factors impacting the discipline were explored, including trends in the workforce, population needs, accessibility, and wait times, as well as issues in undergraduate and postgraduate medical education. The DWG, supported by the RCPSC's Office of Specialty Education, used information gained from the reviews, a national survey, and stakeholder perspectives to develop recommendations that address the current challenges and build upon opportunities for advancement in the specialty.
