Prevalence, Incidence, and Risk of Chronic Obstructive Pulmonary Disease Among Psoriasis Patients.

BACKGROUND: Understanding the relationship between psoriasis and chronic obstructive pulmonary disease (COPD) may enhance disease management. OBJECTIVES: We aimed to determine the (1) prevalence and (2) incidence and risk of COPD in psoriasis patients. RESULTS: The COPD prevalence was 9.64% in psoriasis patients and 6.94% in psoriasis-free patients. The COPD incidence was 10.74 per 1000 person-years in psoriasis patients and 6.36 per 1000 person-years in psoriasis-free patients. Multivariable Cox regression showed no association between psoriasis and COPD development (HR 0.99, p = 0.271). CONCLUSIONS: Our findings suggest that psoriasis is not an independent risk factor for COPD development.

Shared decision-making in psoriasis care: Evaluation of how patients' perception of clinicians' delivery of care changes by age and sex.

BACKGROUND: Shared decision-making (SDM) refers to a collaborative process in which clinicians assist patients in making medically informed, evidence-based decisions that align with their values and preferences. There is a paucity of literature on SDM in dermatology. OBJECTIVE: We aim to assess whether male and female psoriasis patients evaluate their clinicians' engagement in SDM differently across different age groups. METHODS: Cross-sectional study using data from the 2014-2017 and 2019 Medical Expenditure Panel Surveys (MEPS). RESULTS: A weighted total of 7,795,608 psoriasis patients were identified. SDM Scores ranged from 1 to 4, with 4 representing the most favorable patient evaluation of their clinicians' engagement in SDM. We conducted multivariate linear regression to compare mean SDM Scores in male psoriasis patients versus female psoriasis patients across different patient age groups. Female patients ages 60-69 perceived significantly greater clinician engagement in SDM compared to age-matched male patients (female patient perception of SDM 3.65 [95%CI:3.61-3.69] vs. male patient perception of SDM 3.50 [95%CI:3.43-3.58], p<0.005). The same trend of older female patients evaluating their clinicians' engagement in SDM significantly higher than their age-matched male counterparts exists for the age group >70 (p<0.005). No significant differences between male and female patients' evaluations of their clinicians' engagement in SDM were demonstrated in subjects younger than 60. All calculations were adjusted for demographic and clinical factors. CONCLUSIONS: Compared to older male psoriasis patients, older female psoriasis patients evaluated their clinicians to be more engaged in shared decision-making.

An OX-Tra'Ordinary Tale: The Role of OX40 and OX40L in Atopic Dermatitis.

The transmembrane glycoprotein OX40 receptor (OX40) and its ligand, OX40L, are instrumental modulators of the adaptive immune response in humans. OX40 functions as a costimulatory molecule that promotes T cell activation, differentiation, and survival through ligation with OX40L. T cells play an integral role in the pathogenesis of several inflammatory skin conditions, including atopic dermatitis (AD). In particular, T helper 2 (TH2) cells strongly contribute to AD pathogenesis via the production of cytokines associated with type 2 inflammation (e.g., IL-4, IL-5, IL-13, and IL-31) that lead to skin barrier dysfunction and pruritus. The OX40-OX40L interaction also promotes the activation and proliferation of other T helper cell populations (e.g., TH1, TH22, and TH17), and AD patients have demonstrated higher levels of OX40 expression on peripheral blood mononuclear cells than healthy controls. As such, the OX40-OX40L pathway is a potential target for AD treatment. Novel therapies targeting the OX40 pathway are currently in development, several of which have demonstrated promising safety and efficacy results in patients with moderate-to-severe AD. Herein, we review the function of OX40 and the OX40-OX40L signaling pathway, their role in AD pathogenesis, and emerging therapies targeting OX40-OX40L that may offer insights into the future of AD management.

Characterization of online support group resources for patients with dermatologic conditions.

Dermatologic conditions can have significant quality of life effects on patients. The internet is a first-line accessible resource for patients to seek support and community in managing dermatologic diagnoses. The accessibility and content of online support resources for patients with dermatologic conditions is unclear so we sought to characterize these resources. We conducted online searches utilizing incognito Google, Yahoo, and Bing search engines and identified a total of 36 support group resources. 9 links were for single dermatology support groups and 27 links were for databases of support groups for different dermatologic conditions. We tallied number totals and percentages of online support resources and found wide variability of material in terms of the readability of the group websites, as well as content, medium, and hosts of the groups. Furthermore, we observed an imbalance in representation of resources for certain dermatologic conditions as opposed to others, further highlighting the strong need for the creation of easy-to-access support groups for patients across the spectrum of dermatological disease.

Myths and media in oral collagen supplementation for the skin, nails, and hair: A review.

BACKGROUND: As a key component of the hair, skin, and nails, there is strong consumer interest in the dermatologic efficacy of oral collagen supplementation. Oral supplementation with collagen peptides has increased in popularity in recent years. AIMS: There are relatively few studies investigating the dermatologic effects of ingested collagen peptides, many of which are limited by sample size and variability of results. The question remains whether there is sufficient evidence to support companies' promises and consumers' goals. METHODS: In this review, we investigate and compare the claims surrounding collagen supplementation on Instagram and YouTube, made by collagen companies, and established in the literature. RESULTS: Although some studies have demonstrated that collagen supplementation can enhance skin qualities such as elasticity and hydration, dermatologic claims in the media surpass any evidence currently supported by the literature. CONCLUSIONS: More research is needed to establish knowledge of the effects and physiologic mechanism of collagen supplementation. Dermatologists should be aware of the unsubstantiated proclamations of collagen made by companies and in social media, as well as what evidence is established thus far, to be equipped to discuss collagen supplementation with patients.

The Role of Diet Modification in Atopic Dermatitis: Navigating the Complexity.

Diet has long been understood to have an intricate association with atopic dermatitis, although much remains unelucidated. Skin barrier dysfunction with dysbiosis and consequent impairment of immune tolerance likely underly the pathogenesis of coincident atopic dermatitis and food allergy. There is a wide range of possible skin reactions to food, complicating the diagnosis and understanding of food allergies. Many patients, parents, and providers incorrectly suspect diet as causative of atopic dermatitis symptoms and many have tried elimination diets. This frequently leads to inaccurate labeling of food allergies, contributing to a dangerous spiral of inappropriate testing, referrals, and dietary changes, while neglecting established atopic dermatitis treatment essentials. Alternatively, certain dietary supplements or the introduction of certain foods may be beneficial for atopic dermatitis management or prevention. Greater consensus on the role of diet among providers of patients with atopic dermatitis is strongly encouraged to improve the management of atopic dermatitis.

Advances in the Translational Science of Dermatitis.

The cycle of converting mechanistic insight into therapeutic interventions is called translational science. It has been relatively sluggish in atopic dermatitis (AD), but finally pathomechanisms have been identified and therapeutic targets selected and refined. From inflammatory mediators, skin barrier enhancement, itch relief, and alteration of the microbiota, several therapies have been proposed and are actively being studied for AD, suggesting an end to the drought of innovation.

Perioperative Methadone and Ketamine for Postoperative Pain Control in Spinal Surgical Patients: A Randomized, Double-blind, Placebo-controlled Trial.

BACKGROUND: Despite application of multimodal pain management strategies, patients undergoing spinal fusion surgery frequently report severe postoperative pain. Methadone and ketamine, which are N-methyl-d-aspartate receptor antagonists, have been documented to facilitate postoperative pain control. This study therefore tested the primary hypothesis that patients recovering from spinal fusion surgery who are given ketamine and methadone use less hydromorphone on the first postoperative day than those give methadone alone. METHODS: In this randomized, double-blind, placebo-controlled trial, 130 spinal surgery patients were randomized to receive either methadone at 0.2 mg/kg (ideal body weight) intraoperatively and a 5% dextrose in water infusion for 48 h postoperatively (methadone group) or 0.2 mg/kg methadone intraoperatively and a ketamine infusion (0.3 mg · kg-1 · h-1 infusion [no bolus] intraoperatively and then 0.1 mg · kg-1 · h-1 for next 48 h [both medications dosed at ideal body weight]; methadone/ketamine group). Anesthetic care was standardized in all patients. Intravenous hydromorphone use on postoperative day 1 was the primary outcome. Pain scores, intravenous and oral opioid requirements, and patient satisfaction with pain management were assessed for the first 3 postoperative days. RESULTS: Median (interquartile range) intravenous hydromorphone requirements were lower in the methadone/ketamine group on postoperative day 1 (2.0 [1.0 to 3.0] vs. 4.6 [3.2 to 6.6] mg in the methadone group, median difference [95% CI] 2.5 [1.8 to 3.3] mg; P < 0.0001) and postoperative day 2. In addition, fewer oral opioid tablets were needed in the methadone/ketamine group on postoperative day 1 (2 [0 to 3] vs. 4 [0 to 8] in the methadone group; P = 0.001) and postoperative day 3. Pain scores at rest, with coughing, and with movement were lower in the methadone/ketamine group at 23 of the 24 assessment times. Patient-reported satisfaction scores were high in both study groups. CONCLUSIONS: Postoperative analgesia was enhanced by the combination of methadone and ketamine, which act on both N-methyl-d-aspartate and µ-opioid receptors. The combination could be considered in patients having spine surgery.

Neuromuscular and Clinical Recovery in Thoracic Surgical Patients Reversed With Neostigmine or Sugammadex.

BACKGROUND: Patients undergoing thoracoscopic procedures may be at high-risk for incomplete neuromuscular recovery and associated complications. The aim of this clinical investigation was to assess the incidence of postoperative residual neuromuscular blockade in adult thoracic surgical patients administered neostigmine or sugammadex when optimal dosing and reversal strategies for these agents were used. The effect of choice of reversal agent on hypoxemic events and signs and symptoms of muscle weakness were also determined. Additionally, operative conditions in each group were graded by surgeons performing the procedures. METHODS: Two hundred patients undergoing thoracoscopic surgical procedures were enrolled in this nonrandomized controlled trial. One hundred consecutive patients maintained at moderate levels of neuromuscular blockade were reversed with neostigmine (neostigmine group) followed by 100 consecutive patients given sugammadex to antagonize deeper levels of neuromuscular blockade (sugammadex group). Anesthetic and neuromuscular management were standardized. Surgeons rated operative conditions at the conclusion of the procedure on a 4-point scale (grade 1 = excellent to grade 4 = poor). Train-of-four ratios were measured immediately before extubation and at PACU admission (primary outcomes). Postoperatively, patients were assessed for adverse respiratory events and 11 signs and 16 symptoms of muscle weakness. RESULTS: The 2 groups were similar in intraoperative management characteristics. The percentage of patients with residual neuromuscular blockade, defined as a normalized train-of-four ratio <0.9, was significantly greater in the neostigmine group than the sugammadex group at both tracheal extubation (80% vs 6%, respectively, P < .0001) and PACU admission (61% vs 1%, respectively, P < .0001). Patients in the neostigmine group had less optimal operative conditions (median score 2 [good] versus 1 [excellent] in the sugammadex group; P < .0001), and more symptoms of muscle weakness were present in these subjects (median number [interquartile range] 4 [1-8] vs 1 [0-2] in the sugammadex group, P < .0001). No differences between groups in adverse airway events were observed. CONCLUSIONS: Despite the application of strategies documented to reduce the risk of residual neuromuscular blockade, a high percentage of thoracoscopic patients whose neuromuscular blockade was reversed with neostigmine were admitted to the PACU with clinical evidence of residual paralysis. In contrast, muscle weakness was rarely observed in patients whose neuromuscular blockade was antagonized with sugammadex.

Biologics for Allergic Dermatologic Diseases.

PURPOSE OF REVIEW: Atopic dermatitis (AD), chronic spontaneous urticaria (CSU), and allergic contact dermatitis (ACD) represent three important allergic dermatoses with many unmet therapeutic needs. The development of biologic agents has opened the door to both new treatment options and improved understanding of the underlying pathophysiology, both shared and unique for these entities. With several FDA-approved medications available and many more in development, the biologic revolution has begun for allergic dermatoses. RECENT FINDINGS: This is a narrative review on the current state of pathomechanisms and appropriately targeted biologic agents for these three common allergic skin conditions. The importance of Th2 inflammation and the effect of inflammatory cytokines on the skin barrier may help explain the impressive efficacy of biologic agents, while maintaining relative safety. While some of the biologic agents show efficacy across multiple allergic dermatoses, more often it seems these more targeted pathways show accordingly precise efficacy. However, in each disease, multiple agents hold promise, and may be differentiated by safety and adverse effect profile rather than simply by efficacy. New understanding of the pathogenesis of the allergic dermatoses has ushered in a new era of biologic therapies. Competing mechanisms and molecules will continue to be developed and vetted in trials with hopes of continuously refined precision therapies with optimized safety and efficacy profiles.

Postoperative Pain and Analgesic Requirements in the First Year after Intraoperative Methadone for Complex Spine and Cardiac Surgery.

BACKGROUND: Methadone is a long-acting opioid that has been reported to reduce postoperative pain scores and analgesic requirements and may attenuate development of chronic postsurgical pain. The aim of this secondary analysis of two previous trials was to follow up with patients who had received a single intraoperative dose of either methadone or traditional opioids for complex spine or cardiac surgical procedures. METHODS: Preplanned analyses of long-term outcomes were conducted for spinal surgery patients randomized to receive 0.2 mg/kg methadone at the start of surgery or 2 mg hydromorphone at surgical closure, and for cardiac surgery patients randomized to receive 0.3 mg/kg methadone or 12 µg/kg fentanyl intraoperatively. A pain questionnaire assessing the weekly frequency (the primary outcome) and intensity of pain was mailed to subjects 1, 3, 6, and 12 months after surgery. Ordinal data were compared with the Mann-Whitney U test, and nominal data were compared using the chi-square test or Fisher exact probability test. The criterion for rejection of the null hypothesis was P < 0.01. RESULTS: Three months after surgery, patients randomized to receive methadone for spine procedures reported the weekly frequency of chronic pain was less (median score 0 on a 0 to 4 scale [less than once a week] vs. 3 [daily] in the hydromorphone group, P = 0.004). Patients randomized to receive methadone for cardiac surgery reported the frequency of postsurgical pain was less at 1 month (median score 0) than it was in patients randomized to receive fentanyl (median score 2 [twice per week], P = 0.004). CONCLUSIONS: Analgesic benefits of a single dose of intraoperative methadone were observed during the first 3 months after spinal surgery (but not at 6 and 12 months), and during the first month after cardiac surgery, when the intensity and frequency of pain were the greatest.
