Dermatological patients with itch report more stress, stigmatization experience, anxiety and depression compared to patients without itch: Results from a European multi-centre study.

BACKGROUND: Itch as the most common symptom in dermatology has been shown to be related to psychological factors such as stress, anxiety and depression. Moreover, associations were found between perceived stigmatization and itch. However, studies investigating the differences between patients with dermatoses with and without itch regarding perceived stress, stigmatization, anxiety and depression are missing. Therefore, one of the aims of the second study of the European Society for Dermatology and Psychiatry (ESDaP study II) was to investigate these relationships in a large cohort of patients with different itchy dermatoses. RESULTS: 3399 patients with 14 different itchy dermatoses were recruited at 22 centres in 17 European countries. They filled in questionnaires to assess perceived stigmatization, stress, signs of clinically relevant anxiety or depression, itch-related quality of life, the overall health status, itch duration, frequency and intensity. The most significant association between the severity of itching and the perception of stress was observed among individuals with rosacea (correlation coefficient r = 0.314). Similarly, the strongest links between itch intensity and experiences of stigmatization, anxiety, and depression were found in patients with seborrheic dermatitis (correlation coefficients r = 0.317, r = 0.356, and r = 0.400, respectively). Utilizing a stepwise linear regression analysis, it was determined that within the entire patient cohort, 9.3% of the variation in itch intensity could be accounted for by factors including gender, levels of anxiety, depression, and perceived stigmatization. Females and individuals with elevated anxiety, depression, and perceived stigmatization scores reported more pronounced itch intensities compared to those with contrary attributes. CONCLUSION: This study underscores the connection between experiencing itch and its intensity and the psychological strain it places on individuals. Consequently, psychological interventions should encompass both addressing the itch itself and the interconnected psychological factors. In specific cases, it becomes imperative for dermatologists to direct individuals towards suitable healthcare resources to undergo further psychological assessment.

Toxoplasmosis epidemic in a population of urbanised allied rock-wallabies (Petrogale assimilis) on Magnetic Island (Yunbenun), North Queensland.

A mortality event involving 23 allied rock-wallabies (Petrogale assimilis) displaying neurological signs and sudden death occurred in late April to May 2021 in a suburban residential area directly adjacent to Magnetic Island National Park, on Magnetic Island (Yunbenun), North Queensland, Australia. Three allied rock-wallabies were submitted for necropsy, and in all three cases, the cause of death was disseminated toxoplasmosis. This mortality event was unusual because only a small, localised population of native wallabies inhabiting a periurban area on a tropical island in the Great Barrier Reef World Heritage Area were affected. A disease investigation determined the outbreak was likely linked to the presence of free-ranging feral and domesticated cats inhabiting the area. There were no significant deaths of other wallabies or wildlife in the same or other parts of Magnetic Island (Yunbenun) at the time of the outbreak. This is the first reported case of toxoplasmosis in allied rock-wallabies (Petrogale assimilis), and this investigation highlights the importance of protecting native wildlife species from an infectious and potentially fatal parasitic disease.

HTS driven by fluorescence lifetime detection of FRET identifies activators and inhibitors of cardiac myosin.

Small molecules that bind to allosteric sites on target proteins to alter protein function are highly sought in drug discovery. High-throughput screening (HTS) assays are needed to facilitate the direct discovery of allosterically active compounds. We have developed technology for high-throughput time-resolved fluorescence lifetime detection of fluorescence resonance energy transfer (FRET), which enables the detection of allosteric modulators by monitoring changes in protein structure. We tested this approach at the industrial scale by adapting an allosteric FRET sensor of cardiac myosin to high-throughput screening (HTS), based on technology provided by Photonic Pharma and the University of Minnesota, and then used the sensor to screen 1.6 million compounds in the HTS facility at Bristol Myers Squibb. The results identified allosteric activators and inhibitors of cardiac myosin that do not compete with ATP binding, demonstrating high potential for FLT-based drug discovery.

An analysis of qualitative responses from a UK survey of the psychosocial wellbeing of people with skin conditions and their experiences of accessing psychological support.

BACKGROUND: Skin conditions have a large emotional, psychological and psychiatric impact on the individual. The All-Party Parliamentary Group on Skin (APPGS) commissioned a qualitative survey to further explore this relationship alongside the experiences of those accessing services in relation to these difficulties in the UK. AIM: To examine the experiences of UK individuals living with a skin condition, and their views of seeking and receiving psychological treatment. This survey formed part of the evidence collected in the preparation of the APPGS Mental Health and Skin Disease report. METHODS: A free-text electronic survey was widely distributed by professional bodies and skin-related charities. Responses were analysed using descriptive thematic analysis and descriptive statistics. Data for each question were classified and labelled, leading to the development of a coding frame. Inter-rater reliability was assessed using Cohen kappa statistic. RESULTS: In total, 544 participants (84% female) completed the survey. The majority of respondents had inflammatory skin diseases such as eczema (43%) or psoriasis (33%). The thematic analysis revealed five key themes associated with impact on mood; impact of intimacy; impact on activities of daily living; lack of recognition from others of the impact; and lack of accessible services. CONCLUSION: The survey demonstrates that there is an urgent need to improve both awareness of the impact that skin conditions can have, and for the provision of psychological services to address this impact.

Investigating the beneficial experiences of online peer support for those affected by alopecia: an interpretative phenomenological analysis using online interviews.

BACKGROUND: Those affected by alopecia are at risk of experiencing a range of psychosocial consequences. Alopecia UK provides online peer support via facilitated Facebook pages. Online peer support has been found to provide a variety of benefits in other long-term conditions, such as providing information and emotional support. OBJECTIVES: This study sought to gain an experiential account as to how online support provides benefit to people living with alopecia. METHODS: A purposive sample of 12 participants was recruited directly from Alopecia UK's Facebook group. A total of 11 were diagnosed with alopecia and one participant was a family member of someone with alopecia. The qualitative approach of Interpretative Phenomenological Analysis was used to guide data collection and analysis. Participants took part in online synchronous interviews, which drew on review of participant-selected screenshots of online activity. RESULTS: Four themes were identified, including 'gradual healing', 'image concern', 'belonging' and 'new identity and self-acceptance'. The participants made use of the group through expressing emotion, finding practical advice, and also as a place to connect and share experiences. Participants also reported that the online support facilitated the return of social confidence. CONCLUSIONS: This study provides a detailed understanding as to how online peer support groups can be beneficial. Online groups have the potential to create a feeling of belonging, which can develop a sense of being accepted and understood and as such can be important in maintaining psychological well-being. The findings indicate that online groups have the potential to be used as a platform for assisting people in developing both effective coping styles and feeling understood, and such platforms warrant further investment by healthcare professionals. What's already known about this topic? Alopecia may be associated with psychosocial distress due to both the individual impact and the reactions of others. Online peer support is known to be a beneficial method of providing psychosocial support for people living with a range of health conditions. What does this study add? An in-depth view of the benefits experienced through belonging to an online peer support group for those diagnosed with alopecia, in addressing the psychosocial effects experienced with the condition. This research highlights the need for further investigation of the utility of supporting the development of online peer support for people living with skin conditions. Online peer support groups could be highly effective to use in combination with existing psychological therapies to connect others with shared experience. What are the clinical implications of this work? People living with alopecia can benefit from peer support, and healthcare professionals should ensure that patients know where they can gain access to both psychological support and peer support.

The role of adult attachment orientation and coping in psychological adjustment to living with skin conditions.

BACKGROUND: Skin conditions can be associated with significant psychological distress. Investigation of attachment orientation and associated use of coping strategies is a promising perspective from which to investigate psychological adjustment to skin conditions. OBJECTIVES: To examine the role of adult attachment orientation, conceptualized as two dimensions - attachment avoidance and attachment anxiety - in psychological adjustment [appearance-related distress and skin-related quality of life (QoL)], and the mediating role of two coping strategies - defeatism and activity. METHODS: Attachment avoidance and attachment anxiety, use of coping strategies, appearance-related distress and skin-related QoL were assessed via a cross-sectional online survey in 207 adults with skin conditions. Multiple mediation analyses were performed using PROCESS pathway analysis. RESULTS: Overall, higher attachment avoidance and higher attachment anxiety were associated with higher appearance-related distress and greater impact on emotions and functioning aspects of QoL. For attachment anxiety, the relationship was fully explained by more frequent use of defeatism coping. For attachment avoidance, the relationship was partially explained by more frequent use of defeatism coping (and in the case of appearance-related distress also more frequent use of activity coping), and higher attachment avoidance was also associated with poorer psychological adjustment in a way that could not be explained by use of assessed coping strategies. CONCLUSIONS: Insecure attachment orientation (high attachment avoidance or high attachment anxiety) is linked to poorer adjustment. People with insecure attachment might benefit from psychological interventions that target underlying attachment orientation.

The prevalence of psychological comorbidity in people with vitiligo: a systematic review and meta-analysis.

BACKGROUND: Vitiligo is a chronic disorder causing skin depigmentation with global prevalence varying from 0·2% to 1·8%. U.K. guidelines recommend assessment of psychological state during clinical evaluation of vitiligo. However, the prevalence of psychological comorbidity in people with vitiligo has not been described. OBJECTIVES: To establish the prevalence of psychological symptoms or disorders in people with vitiligo and describe the outcome measures used. METHODS: We performed a comprehensive search of MEDLINE, Embase, CINAHL and PsycINFO to identify observational studies assessing the prevalence of psychological symptoms or disorders (December 2016). DerSimonian and Lard random-effects models were used to estimate the overall pooled prevalence. RESULTS: We identified 29 studies with 2530 people with vitiligo. Most studies included a measure of either depression (n = 25) or anxiety (n = 13). The commonest tools were the Hospital Anxiety and Depression Scale and the Centre for Epidemiology Studies Depression Scale. Ten studies provided information on 13 other psychological outcomes. Pooled prevalence using depression-specific and anxiety-specific questionnaires was 0·29 [95% confidence interval (CI) 0·21-0·38] and 0·33 (95% CI 0·18-0·49), respectively. Prevalence was lower for clinically diagnosed depression (0·21, 95% CI 0·15-0·28) and anxiety (0·15, 95% CI 0·06-0·24). When nonspecific tools were used the prevalence remained similar for depression (0·27, 95% CI 0·08-0·46) but increased for anxiety (0·46, 95% CI 0·39-0·52). High heterogeneity was observed. CONCLUSIONS: A range of psychological outcomes are common in people with vitiligo. The prevalence of anxiety was influenced by type of screening tool, suggesting the need for validation of psychological outcome screening tools in the field of dermatology.

Experiences of rosacea and its treatment: an interpretative phenomenological analysis.

BACKGROUND: While rosacea is a chronic skin condition, it can often have a large psychosocial impact on the individual. There is therefore a need to understand the experience of living with rosacea from the patient perspective. OBJECTIVES: To examine the experience of living with rosacea and the experience of seeking and receiving treatment. METHODS: Nine participants took part in semistructured interviews, which were analysed using interpretative phenomenological analysis. RESULTS: Three superordinate themes were identified within the data: 'self-consciousness', which focused on the fear of others assigning blame to participants for having caused symptoms; 'avoidance, concealment and hiding emotions', referring to the coping strategies participants employed in response to rosacea; and 'inconsistencies in general practitioner treatment and guidance', which focused on the need for medical professionals to assess the psychosocial well-being of patients with rosacea. CONCLUSIONS: Rosacea can have a negative impact on the daily life of people with the condition, contributing to lowered self-esteem, embarrassment and feelings of shame. Engaging in emotion-focused and behavioural/avoidant-focused coping strategies increased participants' confidence and reduced their avoidance of social situations. However, such strategies might still serve to maintain underlying unhelpful cognitive processes. Consequently, it is important for medical professionals to assess for the presence of cognitive factors that might contribute to maintaining distress in patients with rosacea, and where unhelpful thoughts or beliefs are reported, patients may need to be referred for psychological support.

The influence of optimism, social support and anxiety on aggression in a sample of dermatology patients: an analysis of cross-sectional data.

BACKGROUND: Individuals with visible skin conditions often experience stigmatization and discrimination. This may trigger maladaptive responses such as feelings of anger and hostility, with negative consequences to social interactions and relationships. OBJECTIVE: To identify psychosocial factors contributing to aggression levels in dermatology patients. METHODS: Data were obtained from 91 participants recruited from outpatient clinics in the north of England, U.K. This study used dermatology-specific data extracted from a large U.K. database of medical conditions collected by The Appearance Research Collaboration. This study looked at the impact of optimism, perceptions of social support and social acceptance, fear of negative evaluation, appearance concern, appearance discrepancy, social comparison and well-being on aggression levels in a sample of dermatology patients. RESULTS: In order to assess the relationship between variables, a hierarchical regression analysis was performed. Dispositional style (optimism) was shown to have a strong negative relationship with aggression (ß = -0·37, t = -2·97, P = 0·004). Higher levels of perceived social support were significantly associated with lower levels of aggression (ß = -0·26, t = -2·26, P = 0·02). Anxiety was also found to have a significant positive relationship with aggression (ß = 0·36, t = 2·56, P = 0·01). CONCLUSIONS: This study provides evidence for the importance of perceived social support and optimism in psychological adjustment to skin conditions. Psychosocial interventions provided to dermatology patients might need to address aggression levels and seek to enhance social support and the ability to be optimistic.

The importance of mindfulness in psychosocial distress and quality of life in dermatology patients.

BACKGROUND: Mindfulness, defined as purposively and nonjudgementally paying attention in the present moment, could be used within psychosocial interventions to reduce the distress associated with social anxiety and avoidance found in many skin conditions. However, little is known about the relationship between naturally occurring levels of mindfulness and distress in dermatology patients. OBJECTIVES: To examine the relationship between mindfulness and psychosocial distress in a dermatological population. It was hypothesized that higher levels of mindfulness would be associated with lower levels of social anxiety, anxiety, depression and skin shame, and with better quality of life. METHODS: Adult dermatology outpatients (n = 120) from one hospital completed items assessing subjective severity, skin shame, fear of negative evaluation, anxiety and depression, quality of life, and levels of mindfulness. RESULTS: Considering depression, 14% reported mild, 5% moderate and 2·5% severe symptoms. For anxiety, 22% reported mild, 23% moderate and 6% severe symptoms. In addition, 33·4% reported clinically significant social anxiety. After controlling for subjective severity, mindfulness explained an additional 19% of the variance in depression, 39% in anxiety, 41% in social anxiety, 13% in skin shame and 6% in dermatological quality of life. One specific facet of mindfulness (acting with awareness) was found to be the most consistent predictor of distress. CONCLUSIONS: The findings indicate that higher levels of mindfulness are associated with lower distress. This suggests that facilitating mindfulness may be helpful in reducing distress in dermatology patients, and the use of mindfulness techniques warrants further investigation.

Analgesic opioid use in a health-insured epilepsy population during 2012.

RATIONALE: Analgesic opioid use has increased dramatically in the general population. Although opioid analgesics are not indicated for the treatment of epilepsy, frequent opioid use has been reported in the epilepsy population. It is not clear whether comorbid disorders and/or epilepsy-associated injuries due to seizures foster opioid use. Our primary objective was to compare the prevalence of analgesic opioid use in an insured patient population with epilepsy to a matched control population without epilepsy. After observing increased frequency of opioid use in people with epilepsy compared with matched controls, we assessed the contribution of age, gender, pain diagnosis, and psychiatric illness as possible drivers regarding the use of opioids. METHODS: Health insurance claims and membership data from nine United States (U.S.) health plans for the year 2012 were analyzed. Individuals with epilepsy (n=10,271) were match-paired at a 1:2 ratio to individuals without epilepsy (n=20,542) within each health plan using propensity scores derived from age group, gender, and insurance type. Matched comparison groups had 53% females and 47% males with an average age of 34 years for the group with epilepsy and 33 years for controls. Each matched comparison group included 66% of individuals with commercial insurance, 30% with Medicaid insurance, and 4% with Medicare coverage. Based on prescriptions filled at least once during 2012, prevalence of analgesic opioid use was determined. The percentages of individuals with diagnosis for specific pain conditions and those with psychiatric diagnoses were also determined for the two comparison groups. RESULTS: Analgesic opioids were used by 26% of individuals in the group with epilepsy vs. 18% of matched controls (p<0.001). Compared with matched controls, the group with epilepsy had a significantly higher percentage of individuals with all 16 pain conditions examined: joint pain or stiffness (16% vs. 11%), abdominal pain (14% vs. 9%), headache (14% vs. 5%), pain in limb (12% vs. 7%), chest pain (11% vs. 6%), sprain of different parts (9% vs. 7%), sinusitis (9% vs. 7%), migraine (8% vs. 2%), lumbago (8% vs. 6%), backache (6% vs. 4%), cervicalgia (6% vs. 3%), fracture (5% vs. 3%), fibromyalgia (4% vs. 3%), chronic pain (3% vs. 1%), sciatica (1.4% vs. 1%), and jaw pain (0.4% vs. 0.1%) (all p<0.001). The prevalence of pain diagnosis was 51% in the group with epilepsy and 39% in the matched control group (p<0.0001). The prevalence of 'psychiatric diagnoses' was 27% in the group with epilepsy and 12% in the matched control group (p<0.0001). CONCLUSION: The prevalences of analgesic opioid use, psychiatric diagnoses, and 16 pain conditions were significantly higher in the patient population with epilepsy than in the control population without epilepsy. Our study also showed how opioid use rate varied by gender, age category, and depression. The reasons for the greater prevalence of opioid use in people with epilepsy are unclear. It seems that increased pain prevalence is an important driver for the higher frequency of opioid use in people with epilepsy. Psychiatric illness and other factors also appear to contribute. Further analysis including more detailed clinical information that cannot be obtained through claims data alone will be required to provide more insight into opioid use in people with epilepsy. If opioid use is higher in people with epilepsy as our results suggest, physicians managing patients with epilepsy need to pay special attention to safe opioid prescribing habits in order to prevent adverse outcomes such as abuse, addiction, diversion, misuse, and overdose.
