Effects of online care on functional and psychological outcomes in patients with psoriasis: A randomized controlled trial.

BACKGROUND: The impact of online care on patients' functional and psychological outcomes is critical to determine yet still unknown. OBJECTIVE: To evaluate how a novel online health model that facilitates physician-patient collaboration compares with in-person care for improving functional status and mental health of patients with psoriasis. METHODS: This 12-month randomized controlled equivalency trial randomly assigned patients with psoriasis 1:1 to receive online or in-person care. Functional impairment and depression were assessed at baseline and at 3-month intervals using the 5-level EuroQol-5 Dimensions index and Patient Health Questionnare-9. RESULTS: Overall, 296 patients were randomly assigned to the online or in-person groups. The between-group difference in overall improvement in the EuroQol Visual Analogue Scale was -0.002 (95% confidence interval, -2.749 to 2.745), falling within an equivalence margin of ±8. The between-group difference in overall improvement in the 5-level EuroQol-5 Dimensions index was 0 (95% confidence interval, -0.003 to 0.003), falling within an equivalence margin of ±0.1. The between-group difference in overall improvement in Patient Health Questionnare-9 score was -0.33 (95% CI, -1.20 to 0.55), falling within an equivalence margin of ±3. LIMITATIONS: Slightly different attrition rates between online and in-person arms (11% vs 9%), but no impact on outcomes. CONCLUSION: The online health model was equivalent to in-person care for reducing functional impairment and depressive symptoms in patients with psoriasis.

Vitiligo Health Education: A Study of Accuracy and Engagement of Online Educational Materials.

INTRODUCTION: Many vitiligo patients seek healthcare information online. However, the accuracy and quality of this information is unknown. OBJECTIVE: To determine the accuracy, quality, viewer engagement, and viewer experience of vitiligo videos on social media. METHODS: We searched the term “vitiligo” on YouTube. Videos were stratified based on source categories. Video accuracy was assessed using DAS and ANDI. Video quality was assessed using GQS. Viewer experience was assessed using AVA. RESULTS: Sixty videos were evaluated for inclusion and exclusion criteria. We evaluated 49 videos with a total of 28.2 million views, 431,416 likes, and 61,976 comments. Of these videos, 27 (55%) were from healthcare sources, and 22 (45%) were from non-healthcare sources. When compared to videos from non-healthcare sources, videos from healthcare sources had significantly higher accuracy scores (ANDI = 3.69 ± 0.16 vs 2.77 ± 0.36; P=0.017 and DAS = 3.72 ± 0.13 vs 3.07 ± 0.28; P=0.029) but significantly fewer views (38,883 vs 1,231,947; P=0.005). Videos from alternative medicine sources had the lowest accuracy scores when compared to the remainder of the videos (ANDI = 0.5 ± 0.13 vs 3.66 ± 0.14; P<0.001 and DAS = 1.25 ± 0.11 vs 3.73 ± 0.11; P<0.001). CONCLUSION: Inaccurate videos on vitiligo are prevalent on social media. Misinformation can lead to potentially harmful interventions and delay in seeking evidence-based care. Videos from healthcare sources were more accurate but were viewed less than those from non-healthcare sources. Further efforts are needed to improve the visibility and viewer experience of accurate healthcare content on social media. J Drugs Dermatol. 2021;20(6):623-629. doi:10.36849/JDD.5835.

An unusual spiculated presentation of follicular porokeratosis.

Follicular porokeratosis is a rare variant of porokeratosis in which the coronoid lamellae are confined to hair follicles. It classically presents with annular plaques with a surrounding keratotic ridge. However, the clinical presentation has shown significant variation in reported cases. We present the case of a 26-year-old man with chronic diffuse follicular spicules associated with alopecia. Clinical findings were suggestive of trichodysplasia spinulosa, but multiple biopsies showed findings consistent with follicular porokeratosis. Diffusely spiculated presentation as present in our patient has not been previously reported in the literature. It is important to recognize the necessity of histopathologic confirmation in a diagnostically challenging condition such as follicular porokeratosis.

Access to Dermatological Care with an Innovative Online Model for Psoriasis Management: Results from a Randomized Controlled Trial.

Background:Many patients with chronic skin diseases lack regular access to dermatologists in the United States and suffer poor clinical outcomes.Introduction:We performed a 12-month randomized controlled trial to evaluate the impact of an online, collaborative connected health (CCH) model for psoriasis management on access to specialty care.Materials and Methods:The 300 enrolled patients were randomized to online or in-person care. We compared distance traveled as well as transportation and in-office waiting time between the two groups and obtained patient and provider perspectives on CCH.Results:At baseline, no differences existed between the groups in difficulties obtaining specialty care. Over 12 months, the mean (standard deviation [SD]) distance traveled to and from appointments was 174.8 (±577.4) km/person for the in-person group and 2.2 (±14.2) km/person for the online group (p = 0.0003). The mean (SD) time spent on transportation and in-office waiting for in-person appointments was 4.0 (±4.5) h/person for the in-person group and 0.1 (±0.4) h/person for the online group (p = 0.0001). Patients found CCH to be safe, accessible, equitable, efficient, effective, and patient-centered. Providers found CCH to be useful for providing psoriasis care.Discussion:The CCH model resulted in significantly less distance traveled as well as transportation and in-office waiting time compared to in-person care. Both patients and providers were highly satisfied with CCH.Conclusions:The CCH model resulted in increased access to specialty care and enabled patient-centered, safe, and effective management of psoriasis patients.

Effectiveness of Online vs In-Person Care for Adults With Psoriasis: A Randomized Clinical Trial.

Importance: Innovative, online models of specialty-care delivery are critical to improving patient access and outcomes. Objective: To determine whether an online, collaborative connected-health model results in equivalent clinical improvements in psoriasis compared with in-person care. Design, Setting, and Participants: The Patient-Centered Outcomes Research Institute Psoriasis Teledermatology Trial is a 12-month, pragmatic, randomized clinical equivalency trial to evaluate the effect of an online model for psoriasis compared with in-person care. Participant recruitment and study visits took place at multicenter ambulatory clinics from February 2, 2015, to August 18, 2017. Participants were adults with psoriasis in Northern California, Southern California, and Colorado. The eligibility criteria were an age of 18 years or older, having physician-diagnosed psoriasis, access to the internet and a digital camera or mobile phone with a camera, and having a primary care physician. Analyses were on an intention-to-treat basis. Interventions: Participants were randomized 1:1 to receive online or in-person care (148 randomized to online care and 148 randomized to in-person care). The online model enabled patients and primary care physicians to access dermatologists online asynchronously. The dermatologists provided assessments, recommendations, education, and prescriptions online. The in-person group sought care in person. The frequency of online or in-person visits was determined by medical necessity. All participants were exposed to their respective interventions for 12 months. Main Outcomes and Measures: The prespecified primary outcome was the difference in improvement in the self-administered Psoriasis Area and Severity Index (PASI) score between the online and in-person groups. Prespecified secondary outcomes included body surface area (BSA) affected by psoriasis and the patient global assessment score. Results: Of the 296 randomized participants, 147 were women, 149 were men, 187 were white, and the mean (SD) age was 49 (14) years. The adjusted difference between the online and in-person groups in the mean change in the self-administered PASI score during the 12-month study period was -0.27 (95% CI, -0.85 to 0.31). The difference in the mean change in BSA affected by psoriasis between the 2 groups was -0.05% (95% CI, -1.58% to 1.48%). Between-group differences in the PASI score and BSA were within prespecified equivalence margins, which demonstrated equivalence between the 2 interventions. The difference in the mean change in the patient global assessment score between the 2 groups was -0.11 (95% CI, -0.32 to 0.10), which exceeded the equivalence margin, with the online group displaying greater improvement. Conclusions and Relevance: The online, collaborative connected-health model was as effective as in-person management in improving clinical outcomes among patients with psoriasis. Innovative telehealth delivery models that emphasize collaboration, quality, and efficiency can be transformative to improving patient-centered outcomes in chronic diseases.

An update on psoriasis and metabolic syndrome: A meta-analysis of observational studies.

The relationship between psoriasis and metabolic syndrome is not well understood. Though multiple epidemiologic studies have suggested a link between psoriasis and metabolic syndrome, there is a lack of a comprehensive meta-analysis synthesizing the results of all available observational studies to date. In this meta-analysis, we examined global data on the relationship between psoriasis and odds of metabolic syndrome by searching for studies published between 1946-2016. Specifically, we analyzed the results from 35 observational studies from 20 countries with 1,450,188 total participants, of which 46,714 were psoriasis patients. The pooled odds ratio based on random effects analysis was 2.14 (95% CI 1.84-2.48). Publication bias was present, as evidenced by an Egger test and graphical visualization through a funnel plot (p = 0.001). Based on this comprehensive meta-analysis, psoriasis patients have higher odds of having metabolic syndrome when compared with the general population.

Psoriasis and wound healing outcomes: A retrospective cohort study examining wound complications and antibiotic use.

Little is known about wound healing in psoriasis. We performed a cohort study examining differences in wound healing complications between patients with and without psoriasis. Psoriasis patients with traumatic wounds were matched 1:3 to non-psoriasis patients with traumatic wounds based on age, gender, and body mass index (BMI). We examined theincidence of wound complications including infection, necrosis, and hematoma as well as incident antibiotic use within three months following diagnosis of a traumatic wound. The study included 164 patients with traumatic wounds, comprised of 41 patients with psoriasis matched to 123 patients without psoriasis. No statistically significant differences were detected in the incidence of overall wound complications between wound patients with psoriasis and wound patients without psoriasis (14.6% versus. 13.0%, HR 1.18, CI 0.39-3.56). After adjustment for diabetes, peripheral vascular disease, and smoking, no statistically significant differences were detected in the incidence of overall wound complications between patients with and without psoriasis (HR 1.11, CI 0.34-3.58). Specifically, the adjusted rates of antibiotic use were not significantly different between those with and without psoriasis (HR 0.65, CI 0.29-1.46). The incidence of wound complications following traumatic wounds of the skin was found to be similar between patients with and without psoriasis.

Combination Extended Smoking Cessation Treatment Plus Home Visits for Smokers With Schizophrenia: A Randomized Controlled Trial.

INTRODUCTION: The majority of people with schizophrenia have a diagnosis of tobacco dependence during their lifetime. A major obstacle to reducing the burden of cigarette smoking in this population is that these smokers have lower quit rates when undergoing standard treatment compared to smokers with no mental illness. We sought to determine if combination extended treatment (COMB-EXT) and home visits (HV) would lead to improved outcomes in smokers with schizophrenia. METHODS: Thirty-four cigarette smokers with schizophrenia completed either COMB-EXT with HV, COMB-EXT without HV, or treatment as usual (TAU) (random assignment). COMB-EXT consisted of group cognitive-behavioral therapy (CBT), bupropion, nicotine patch, and nicotine lozenge, which were initiated within 2 weeks and continued for 26 weekly visits. HV consisted of biweekly visits to the home with assessment of secondhand smoke (SHS) exposure and brief behavioral therapy with participants and others in the home environment. TAU consisted of group CBT plus serial single or combination medication trials as per standard care. RESULTS: Smokers with schizophrenia who received COMB-EXT (with or without HV) had greater reductions in cigarettes per day than those treated with TAU (both ps < .01). In addition, 7-day point prevalence abstinence rates for the three groups were 45%, 20%, and 8%, respectively, which was significantly higher for COMB-EXT plus HV than TAU (χ2(1) = 4.8, p = .03). Groups did not differ significantly in the number of adverse events, and HV were easily scheduled. CONCLUSION: COMB-EXT improves outcomes for smokers with schizophrenia. HV appeared to provide additional benefit for smoking cessation in this treatment-resistant population. IMPLICATIONS: The clear benefit found here of rapidly initiated, combination, extended treatment over TAU suggests that aggressive and extended treatment should be considered in clinical practice for smokers with schizophrenia. Furthermore, HV to address SHS exposure showed initial promise for assisting smokers with schizophrenia in maintaining abstinence, indicating that this intervention may be worthy of future research.

Relationship between psoriasis and metabolic syndrome: a systematic review.

INTRODUCTION: A number of studies have suggested an epidemiologic association between metabolic syndrome and psoriasis. A systematic review of the literature is necessary to determine whether the synthesis and interpretation of recent studies support the relationship between psoriasis and metabolic syndrome. The objective of this study conducted a comprehensive systematic review that synthesizes and interprets primary observational studies in order to elucidate the relationship between psoriasis and metabolic syndrome. EVIDENCE ACQUISITION: We performed a systematic review search using the MEDLINE, EMBASE, Cochrane Central Register, and SCOPUS databases (1946-2016) and performed a manual search of selected references. We identified English-language, human-subject, observational studies that examined the prevalence of metabolic syndrome in conjunction with psoriasis. EVIDENCE SYNTHESIS: We included data from 17 articles with an aggregate of 28,939 participants, among whom 3791 were psoriasis patients. Overall, the studies reported a higher prevalence of metabolic syndrome in patients with psoriasis. The odds ratio (OR) for metabolic syndrome and psoriasis ranged from 1.39-4.49, and the adjusted OR ranged from 1.29 to 5.14. The studies reported a higher prevalence of the individual components of metabolic syndrome in patients with psoriasis. A dose-response relationship was observed between psoriasis severity and the prevalence of metabolic syndrome. Due to the scarcity of cohort studies, it is difficult to fully examine the impact of psoriasis on the development of metabolic syndrome. Variability in how outcomes were recorded existed among some studies, which made between-study comparisons difficult. CONCLUSIONS: Psoriasis patients have a greater prevalence of metabolic syndrome as well as its individual components when compared to the general population. The odds of metabolic syndrome and its components are higher with increased psoriasis disease severity. Prospective studies are needed to better understand the contribution of psoriasis in the development of metabolic syndrome.

Nicotinic acetylcholine receptor availability in cigarette smokers: effect of heavy caffeine or marijuana use.

RATIONALE: Upregulation of α4ß2* nicotinic acetylcholine receptors (nAChRs) is one of the most well-established effects of chronic cigarette smoking on the brain. Prior research by our group gave a preliminary indication that cigarette smokers with concomitant use of caffeine or marijuana have altered nAChR availability. OBJECTIVE: We sought to determine if smokers with heavy caffeine or marijuana use have different levels of α4ß2* nAChRs than smokers without these drug usages. METHODS: One hundred and one positron emission tomography (PET) scans, using the radiotracer 2-FA (a ligand for ß2*-containing nAChRs), were obtained from four groups of males: non-smokers without heavy caffeine or marijuana use, smokers without heavy caffeine or marijuana use, smokers with heavy caffeine use (mean four coffee cups per day), and smokers with heavy marijuana use (mean 22 days of use per month). Total distribution volume (Vt/fp) was determined for the brainstem, prefrontal cortex, and thalamus, as a measure of nAChR availability. RESULTS: A significant between-group effect was found, resulting from the heavy caffeine and marijuana groups having the highest Vt/fp values (especially for the brainstem and prefrontal cortex), followed by smokers without such use, followed by non-smokers. Direct between-group comparisons revealed significant differences for Vt/fp values between the smoker groups with and without heavy caffeine or marijuana use. CONCLUSIONS: Smokers with heavy caffeine or marijuana use have higher α4ß2* nAChR availability than smokers without these drug usages. These findings are likely due to increased nicotine exposure but could also be due to an interaction on a cellular/molecular level.
