Abstract
Psoriasis is a chronic, hereditary disease with a complex immunopathogenesis, rendering it susceptible to misinformation. Misinformation related to psoriasis can have negative effects both on the public perception of psoriasis and on patients' knowledge of psoriasis. To characterize misinformation related to psoriasis available online, we performed a formal literature review via PubMed and a thematic review via Google. Key themes of misinformation included 'victim-blaming' (hygiene), 'vector' (contagion), 'vaccination', 'vilification' of conventional therapy, 'validation' of natural treatment and diet, 'veneration' of cures and 'vocalization' from celebrities. Misinformation related to psoriasis is pervasive on social media and other websites. Dermatologists, as patient advocates, should be aware of the content of misinformation available online and combat misleading health information to optimize health outcomes for patients with psoriasis.

Abstract
We present a search for the decays of a neutral scalar boson produced by kaons decaying at rest, in the context of the Higgs portal model, using the MicroBooNE detector. We analyze data triggered in time with the Fermilab NuMI neutrino beam spill, with an exposure of 1.93×10^{20} protons on target. We look for monoenergetic scalars that come from the direction of the NuMI hadron absorber, at a distance of 100 m from the detector, and decay to electron-positron pairs. We observe one candidate event, with a standard model background prediction of 1.9±0.8. We set an upper limit on the scalar-Higgs mixing angle of θ<(3.3-4.6)×10^{-4} at the 95% confidence level for scalar boson masses in the range (100-200) MeV/c^{2}. We exclude, at the 95% confidence level, the remaining model parameters required to explain the central value of a possible excess of K_{L}^{0}→π^{0}νν[over ¯] decays reported by the KOTO collaboration. We also provide a model-independent limit on a new boson X produced in K→πX decays and decaying to e^{+}e^{-}.

Acute regional changes in myocardial strain may predict ventricular remodelling after myocardial infarction in a large animal model. Sci Rep 2021; 11:18322.

Abstract
To identify predictors of left ventricular remodelling (LVR) post-myocardial infarction (MI) and related molecular signatures, a porcine model of closed-chest balloon MI was used along with serial cardiac magnetic resonance imaging (CMRI) up to 5-6 weeks post-MI. Changes in myocardial strain and strain rates were derived from CMRI data. Tissue proteomics was compared between infarcted and non-infarcted territories. Peak values of left ventricular (LV) apical circumferential strain (ACS) changed over time together with peak global circumferential strain (GCS) while peak GLS epicardial strains or strain rates did not change over time. Early LVR post-MI enhanced abundance of 39 proteins in infarcted LV territories, 21 of which correlated with LV equatorial circumferential strain rate. The strongest associations were observed for D-3-phosphoglycerate dehydrogenase (D-3PGDH), cysteine and glycine-rich protein-2, and secreted frizzled-related protein 1 (sFRP1). This study shows that early changes in regional peak ACS persist at 5-6 weeks post-MI, when early LVR is observed along with increased tissue levels of D-3PGDH and sFRP1. More studies are needed to ascertain if the observed increase in tissue levels of D-3PGDH and sFRP1 might be casually involved in the pathogenesis of adverse LV remodelling.

Abstract
To assess Irish dermatologists' confidence with dermatology in patients with skin of colour (SOC), an online survey was distributed to all members of the Irish Association of Dermatology (IAD) by email. Half (50%) of respondents were 'not confident' or 'not at all confident' in diagnosing skin conditions and one-third (33.9%) were 'not confident' or 'not at all confident' in managing skin conditions in patients with SOC. Irish dermatologists have low confidence with skin pathology in SOC, and specific training could reduce this disparity.

Abstract
Lichen sclerosus (LS) is a chronic inflammatory dermatosis that predominantly affects the anogenital region. The diagnosis of LS is a clinical diagnosis and a confirmatory biopsy is not always required if typical clinical features are present. A biopsy is recommended if the clinical presentation is atypical or if there is diagnostic uncertainty.1 Topical corticosteroids (TCS) have been a mainstay in the treatment of inflammatory skin conditions, including LS, for decades. TCS have been recommended as first-line treatment for LS in international guidelines since at least 2002.2 There is ample evidence to support the long-term efficacy and safety of TCS. Despite this, several studies have demonstrated suboptimal compliance with prescribed TCS therapy among patients with dermatological conditions, including LS. 3,4,5 Concerns regarding safety of TCS, also described as corticosteroid phobia, have been among the most commonly reported reasons for non-adherence to treatment.5,6,7 In recent years it has been demonstrated that corticosteroid phobia is prominent among pharmacists and general practitioners, and that these health care professionals may in fact contribute towards patient concerns regarding TCS use, by emphasising their side effect profile, and by instructing patients to use TCS sparingly.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by the formation of nodules, abscesses, and fistula at intertriginous sites. The skin-gut axis is an area of emerging research in inflammatory skin disease and is a potential contributory factor to the pathogenesis of HS. 59 patients with HS provided fecal samples, nasal and skin swabs of affected sites for analysis. 30 healthy controls provided fecal samples and 20 healthy controls provided nasal and skin swabs. We performed bacterial 16S rRNA gene amplicon sequencing on total DNA derived from the samples. Microbiome alpha diversity was significantly lower in the fecal, skin and nasal samples of individuals with HS which may be secondary to disease biology or related to antibiotic usage. Ruminococcus gnavus was more abundant in the fecal microbiome of individuals with HS, which is also reported in Crohn's disease (CD), suggesting comorbidity due to shared gut microbiota alterations. Finegoldia magna was over-abundant in HS skin samples relative to healthy controls. It is possible local inflammation is driven by F. magna through promoting the formation of neutrophil extracellular traps (NET). These alterations in both the gut and skin microbiome in HS warrant further exploration, and therapeutic strategies including fecal microbiota transplant (FMT) or bacteriotherapy could be of benefit.

Abstract
Background:Cenerimod is a potent, selective, and orally active sphingosine 1-phosphate receptor 1 (S1P1) modulator that is currently being evaluated in a Phase 2b study in patients with systemic lupus erythematosus (SLE) (NCT03742037). S1P1 receptor modulators sequester circulating lymphocytes within lymph nodes, thereby reducing pathogenic autoimmune cells (including B lymphocytes) in the blood stream and in inflamed tissues. Extensive clinical experience has become available for the nonselective S1P receptor modulator fingolimod in relapsing forms of multiple sclerosis, supporting this therapeutic concept for the treatment of autoimmune disorders.Objectives:Although the effect of S1P-receptor modulators in reducing peripheral B cells is well documented1,2, the role of the S1P1 receptor on this cell type is only incompletely understood. In this study, the mode of action of cenerimod on primary human B cells was investigated in a series of in vitro experiments, including S1P1 receptor cell surface expression and chemotaxis towards S1P. Moreover, S1P1 expression following B cell activation in vitro was studied. As glucocorticoids (GC) are frequently used in the treatment of patients with autoimmune disorders including SLE, the potential influence of GC on the mode of action of cenerimod was evaluated.Methods:Primary human B lymphocytes from healthy donors were isolated from whole blood. In one set of experiments, cells were treated with different concentrations of cenerimod to measure S1P1 receptor internalization by flow cytometry. In a second set of experiments, isolated B cells were activated using different stimuli or left untreated. Cells were then analysed for S1P1 and CD69 cell surface expression and tested in a novel real-time S1P-mediated migration assay. In addition, the effect of physiological concentrations of GCs (prednisolone and prednisone) on cenerimod activity in preventing S1P mediated migration was tested.Results:In vitro, cenerimod led to a dose-dependent internalization of the S1P1 receptor on primary human B lymphocytes. Cenerimod also blocked migration of nonactivated and activated B lymphocytes towards S1P in a concentration-dependent manner, which is in line with the retention of lymphocytes in the lymph node and the reduction of circulating lymphocytes observed in the clinical setting. Upon B cell activation, which was monitored by CD69 upregulation, a simultaneous downregulation of S1P1 expression was detected, leading to less efficient S1P-directed cell migration. Importantly, physiological concentrations of GC did not affect the inhibitory activity of cenerimod on B cell migration.Conclusion:These results show that cenerimod, by modulating S1P1, blocks B lymphocyte migration towards its natural chemoattractant S1P and demonstrate compatibility of cenerimod with GC. These results are consistent with results of comparable experiments done previously using primary human T lymphocytes.References:[1]Nakamura M et al., Mult Scler. 2014 Sep; 20(10):1371-80.[2]Strasser DS et al., RMD Open 2020;6:e001261.Disclosure of Interests:None declared

Abstract
Misinformation is one of the greatest threats to global health. Atopic dermatitis (AD) is a common skin disorder with a complex multifactorial aetiology, rendering it susceptible to misinformation. Little is known about the content of misinformation regarding AD online. We performed a review of AD-related misinformation available online, via PubMed for scientific papers and Google for nonscientific websites. Key areas of misinformation were identified, including 'simple cures' for AD, diet, chemicals, dust, vaccines, red skin syndrome and alternative therapies. Patients with AD and their families are vulnerable to misinformation given the severe impact of AD on quality of life. Dermatologists must be aware of the false AD-related content being shared online, and be prepared to refute and rebut misinformation by providing appropriate evidence.

Older adults with cancer often require multiple medications (polypharmacy) comprising cancer-specific treatments, supportive care medications (e.g. analgesics) and medications for pre-existing conditions. The reported prevalence of polypharmacy in older adults with cancer ranges from 13–92% (1). Increasing numbers of medications pose risks of potentially inappropriate prescribing and medication non-adherence.
Aim
The aim of this scoping review was to provide an overview of evaluations of interventions to optimise medication prescribing and/or adherence in older adults with cancer, with a particular focus on the interventions, study populations and outcome measures that have been assessed in previous evaluations.
Methods
Four databases (PubMed, EMBASE, CINAHL, PsycINFO) were searched from inception to 29th November 2019 using relevant search terms (e.g. cancer, older adults, prescribing, adherence). Eligible studies evaluated interventions seeking to improve medication prescribing and/or adherence in older adults (≥65 years) with an active cancer diagnosis using a comparative evaluation (e.g. inclusion of a control group). All outcomes for studies that met inclusion criteria were included in the review. Two reviewers independently screened relevant abstracts for inclusion and performed data extraction. As a scoping review aims to provide a broad overview of existing literature, formal assessments of methodological quality of included studies were not undertaken. Extracted data were collated using tables and accompanying narrative descriptive summaries. The review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) guidelines (2).
Results
The electronic searches yielded 21,136 citations (Figure 1). Nine studies met inclusion criteria. Included studies consisted of five randomised controlled trials (RCTs), including one cluster RCT, and four before-and-after study designs. Studies were primarily conducted in oncology clinics, ranging from single study sites to 109 oncology clinics. Sample sizes ranged from 33 to 4844 patients. All studies had a sample population with a mean/median age of ≥65 years, however, only two studies focused specifically on older populations. Interventions most commonly involved patient education (n=6), and were delivered by pharmacists or nurses. Five studies referred to the intervention development process and no studies reported any theoretical underpinning. Three studies reported on prescribing-related outcomes and seven studies reported on adherence-related outcomes, using different terminology and a range of assessments. Prescribing-related outcomes comprised assessments of medication appropriateness (using Beers criteria), drug-related problems and drug interactions. Adherence-related outcomes included assessments of self-reported medication adherence and calculation of patients’ medication possession ratio.
Conclusion
The main strength of this scoping review is that it provides a broad overview of the existing literature on interventions aimed at optimising medication prescribing and adherence in older adults with cancer. The review highlights a lack of robust studies specifically targeting this patient population and limited scope to pool outcome data across included studies. Limitations of the review were that searches were restricted to English language publications and no grey literature was searched. Future research should focus specifically on older patients with cancer, and exercise rigour during intervention development, evaluation and reporting in order to generate findings that could inform future practice.

Abstract
Full skin examination (FSE) may improve the detection of malignant melanoma (MM). The objective of this study was to assess the safety of targeted lesion examination (TLE) compared with FSE in our Pigmented Lesion Clinic (PLC). Patients attending the PLC were randomized in a 2 : 1 ratio to FSE (intervention) or TLE (standard care). Demographic details and risk factors were documented, and the time taken to perform FSE and TLE was noted. Of 763 participants, 520 were assigned to FSE and 243 were assigned to TLE. On average, FSE took 4.02 min and TLE took 30 s to perform. Of the 520 participants assigned to FSE, 37 (7.1%) had incidental findings, of whom 12 patients (2.3%) had additional lesions biopsied. No additional melanomas were detected that would have been missed by use of the standard protocol. This study suggests that in low-risk patients referred to a PLC with a lesion of concern, the possibility of missing incidental cutaneous malignancies using lesion-directed examination is low.

Abstract
This study evaluated the effect of harvest date and forage species on the concentration of hydroxycinnamic acids in silage and its relationship to dairy cow performance. Tall fescue and timothy were harvested at a regular date on June 27 and July 8, respectively, or at a late date on July 8 and 25, respectively, in the first regrowth. Forage was treated with a salt-based additive and ensiled in hard-pressed round bales. Forty-seven lactating dairy cows were used in a block design. Cows received 1 of 4 treatments: (1) tall fescue harvested at regular date (RTF), (2) timothy harvested at regular date (RTI), (3) tall fescue harvested at late date (LTF), and (4) timothy harvested at late date (LTI). Diets were formulated to have the same forage-to-concentrate ratio (46:54 on a dry matter basis). Harvesting at late date increased fiber components, but only for timothy, where LTI contained greater neutral detergent fiber, acid detergent fiber, and acid detergent lignin concentrations than the other silages. Concentrations of hydroxycinnamic acids were affected by forage species, where concentrations of esterified ferulic acid and p-coumaric acid were greater for tall fescue silages than for timothy silages. Cows fed the RTI diet showed the greatest intakes of dry matter, organic matter, and crude protein. Feeding diets containing timothy silages increased milk yield and energy-corrected milk yield compared with tall fescue diets when averaged over harvest dates. Cows fed the RTI diet had greater milk protein yield than cows fed the RTF and LTF diets, and milk lactose yield was greater for cows fed diets containing timothy silage compared with tall fescue silage when averaged over harvest dates. Cows fed the LTF diet showed greater urinary N excretion compared with the LTI diet, but RTI showed the lowest urinary N and urea N excretions when calculated as percent of N intake. Cows fed diets containing timothy silage excreted more uric acid than cows fed tall fescue diets. Allantoin excretion was greater for cows eating the RTI and LTI diets compared with cows eating the RTF diet. Cows fed the RTI diet had a greater estimated microbial N flow and a greater excretion of hippuric acid than the RTF and LTF groups. In conclusion, besides the effect of harvest date on increasing the fiber components of timothy, concentrations of hydroxycinnamic acids were mainly affected by forage species; consequently, milk production was only affected by forage species. This indicates that hydroxycinnamic acids, such as ferulic acid, which cross-links to glucuronoarabinoxylans, was a major factor regulating milk production of cows fed tall fescue- and timothy silage-based diets, where lower hydroxycinnamic acid concentrations were responsible for greater milk yield.

Abstract
Triple Negative Breast Cancer (TNBC) is an aggressive tumour with patients survival rarely exceeding five years. TNBC tumours are larger in size, more chemoresistant, highly proliferative and usually more enriched in stem and immune cells comparing to other breast cancer subtypes. Functionally, these changes are dependent on a high-quality mitochondrial pool. Mitochondrial health is constantly assessed and appropriately improved by mitochondrial dynamics (cycles of mitochondrial fusion and division). Recent advances in understanding of mitochondrial dynamics in TNBC has demonstrated its critical importance in tumour growth and metastasis. This review explores current knowledge of mitochondrial dynamics in TNBC and discusses targeting this pathway clinically to improve outcomes for patients.
