Dectin-2-mediated signaling leads to delayed skin wound healing through enhanced neutrophilic inflammatory response and neutrophil extracellular traps formation
Dendritic cell-associated C-type lectin-2 (Dectin-2) recognizes fungal polysaccharides, including α-mannan. Dectin-2-mediated recognition of fungi, such as Candida albicans, leads to NF-κB activation, which induces production of inflammatory cytokines. However, Dectin-2's role in skin wound healing remains unclear. In this study, we sought to determine how Dectin-2 deficiency and the administration of α-mannan affected the wound healing process. Full-thickness wounds were created on the backs of wild type (WT) C57BL/6 and Dectin-2-deficient (KO) mice.
Reconstituting human cutaneous regeneration in humanized mice under endothelial cell therapy
Much of our understanding of human biology and the function of mammalian cells in tissue regeneration have been derived from mechanistically and genetically manipulated rodent models. However, current models examining epidermal wound repair fail to simultaneously address both the cross-species mechanistic and immunogenic differences. Herein, we describe a multifaceted approach intended to better recapitulate human skin recovery in rodent models. First, immunodeficient NSG mice were intravenously inoculated with human hematopoietic stem cells to become in essence, humanized, and capable of initiating an adaptive immune response.
The AHR regulates metabolic reprogramming to promote SIRT1-dependent keratinocyte differentiation
Activation of the transcription factor, the aryl hydrocarbon receptor (AHR), in normal human epidermal keratinocytes (NHEKs) increased AHR binding in the promoters of the glucose transporter, SLC2A1, and the glycolytic enzyme, enolase 1 (ENO1). This increased chromatin binding corresponded with AHR-dependent decreases in levels of SLC2A1 and ENO1 mRNA, protein and activities. Studies of the ENO1 promoter showed activation of the AHR decreases the transcription of ENO1. Glycolysis was lowered by activation of the AHR as measured by decreases in glucose uptake and the production of pyruvate and lactate.
Production of Extracellular Adenosine by CD73+ Dendritic Cells is Crucial for Induction of Tolerance in Contact Hypersensitivity Reactions
Dendritic cells (DC) express the ecto-5'-nucleotidase CD73 that generates immunosuppressive adenosine (Ado) by dephosphorylation of extracellular adenosine mono- and -diphosphate. To investigate whether CD73-derived Ado has immune suppressive activity, 2,4-dinitrothiocyanobenzene (DNTB) was applied to skin of wildtype (WT) or CD73 deficient (CD73-/-) mice, followed by sensitization and challenge with 2,4-dinitrofluorobenzene (DNFB). In this model we demonstrate induction of tolerance by DNTB against DNFB only in W T but not in CD73-/- mice.
Adiponectin enhances human keratinocyte lipid synthesis via SIRT1 and nuclear hormone receptor signaling
Adiponectin is known to have beneficial effects on lipid and insulin metabolism, wound healing, and cellular senescence, but its effect on skin barrier formation remains unknown. We investigated the effects of adiponectin on keratinocyte lipid synthesis with respect to skin barrier function. Lipid staining revealed an adiponectin-mediated increase in keratinocyte intracellular and reconstructed epidermal lipid content. Moreover, significant increases in the levels of ceramide and its downstream metabolites (sphingosine and sphingosine-1-phosphate) following adiponectin stimulation were detected using liquid chromatography–mass spectrometry.
Morphological Plasticity of Human Melanoma Cells is Determined by Nanoscopic Patterns of E- and N-Cadherin Interactions
Loss of E-cadherin and concomitant up-regulation of N-cadherin is known as the cadherin switch and has been implicated in melanoma progression. Mechanistically, homophilic ligation of N-cadherin-expressing melanoma cells with N-cadherin presented within the micro-environment is thought to facilitate invasion. However, the biophysical aspects governing molecular specificity and function of such interactions remain unclear. By using precisely defined nano-patterns of N- or E-cadherin (with densities tunable by more than one order of magnitude, from 78 to 1,128 ligands/μm2), we analyzed adhesion and spreading of six different human melanoma cell lines with distinct constitutive cadherin expression patterns.
Chemoprotective effects of dietary grape powder on ultraviolet B radiation-mediated skin carcinogenesis in SKH-1 hairless mice
Skin cancer is the most frequently diagnosed cancer in the US, and solar ultraviolet (UV) radiation is an established causative factor for ∼90% of these cases. Despite efforts aimed at UV protection, including use of sunscreen and clothing, annual cases of skin cancers continue to rise. Here, we report that dietary grape powder (GP) mitigates UVB-mediated skin carcinogenesis in SKH-1 hairless mouse model. Employing a UVB initiation-promotion protocol, where mice were exposed to 180 mJ/cm2 UVB 2x/week for 28 weeks, we determined the effects of GP-fortified diet (3% or 5%) on skin carcinogenesis.
Phenotypic Spectrum of Epidermolysis Bullosa, the Paradigm of Syndromic Versus Non-Syndromic Skin Fragility Disorders
The heritable forms of epidermolysis bullosa (EB), a phenotypically heterogeneous group of skin fragility disorders, is currently associated with mutations in as many as 21 distinct genes. EB is primarily a disorder affecting the epithelial layers of skin and mucous membranes, without extracutaneous manifestations, and thus being non-syndromic. However, recent demonstrations of skin blistering in the spectrum of EB in multisystem disorders with single gene defects highlight the concept of syndromic EB.
Present and future perspective of photodynamic therapy for cutaneous squamous cell carcinoma
Photodynamic therapy may benefit patients with cutaneous squamous cell carcinoma who are not eligible for surgery. Photodynamic therapy can be modified to provide better effect by use of microneedles or laser, by use of intralesional injection of photosensitizers instead of topical application, by use of nanoparticles or by use of adjuncts.

Abstract
Trichoderma species are saprophytic filamentous fungi that can be found all over the word. These fungi show increasing medical importance as opportunistic human pathogens, particularly in immunocompromised patients. Invasive infections due to Trichoderma are rare and definitive diagnosis is complex to achieve because of the lack of specific diagnosis tools. We report in this work the first proven case of invasive pulmonary infection due to T. longibrachiatum in a 69-year-old white male with hematologic malignancy. The patient was successfully treated initially with voriconazole alone followed by a combination of voriconazole and caspofungine.

Abstract
Background
There is a significant need for novel, safe and efficacious topical treatments for psoriasis.
Objective
We assessed the safety and efficacy of tapinarof in a new cream formulation in 2 concentrations and 2 application frequencies in adults with psoriasis.
Methods
Double-blind, vehicle-controlled, randomized, 6-arm trial (1:1:1:1:1:1) in adults, with psoriasis with body surface (BSA) involvement ≥1% and ≤15% and PGA ≥2 at Baseline. Primary endpoint included PGA = 0 or 1 at Week 12, and a 2-grade improvement from Baseline. Additional analyses included PASI75 and mean percent change in PASI and BSA.
Results
Treatment success defined by PGA 0 or 1 and a 2-Grade Improvement at Week 12 were statistically significantly higher (at a 0.05 significance level) in the tapinarof groups than the vehicle groups: (65% [1%BID]; 56% [1%QD]; 46% [0.5%BID]; 36% [0.5%QD]; 11% [vehicle BID], and 5% [vehicle QD]) and was maintained for 4 weeks post-treatment. Treatment-emergent adverse events (TEAEs) were higher with tapinarof (85/152 patients [56%] compared to vehicle 19/75 patients [25%]) and mild-to-moderate in intensity. Severe TEAEs were reported in all tapinarof groups except 0.5% QD.
Limitations
Large confirmation trials are needed.
Conclusions
Tapinarof cream is efficacious and well tolerated in adult patients with psoriasis.

Abstract
Background
Severe cutaneous adverse reactions (SCARs) are frequent in inpatient oncology. Early intervention may reduce morbidity, mortality, and hospitalization costs, however current clinical and histologic features are unreliable SCAR predictors. There is a need to identify rational markers of SCARs that could lead to effective therapeutic interventions.
Objective
To characterize the clinical and serologic features of hospitalized patients with cancer who developed SCARs.
Methods
Retrospective review of 49 hospitalized cancer patients with a morbilliform rash and recorded testing for serum cytokines (IL-6, IL-10, TNF-α) or elafin, and prior dermatology consultation. Patients were categorized as having a 'simple' morbilliform rash without systemic involvement or 'complex' morbilliform rash with systemic involvement.
Results
Fifteen out of 49 patients (30.6%) were deceased at 6 months from time of dermatologic consultation. Elafin, IL-6, and TNF-α were significantly higher in patients who died compared to patients who were still alive at 6 months. IL-6 and IL-10 were significantly higher in patients with a drug-related 'complex' rash.
Limitations
Retrospective design, limited sample size, high-risk patient population.
Conclusion
In cancer patients with SCARs, elafin, IL-6, and TNF- α may predict a poor outcome. Agents directed towards these targets may represent rational treatments for the prevention of fatal SCARs.

Résumé
Introduction
Malgré les recommandations régulières émises par l'European Society for Medical Oncology (ESMO), la prise en charge des lésions des tissus mous est encore trop souvent insuffisante, pouvant aggraver le pronostic fonctionnel mais aussi vital du patient.
Méthode
Une étude a été menée au centre de référence de Lorraine. Tous Les patients inscrits dans la base de données NetSarc, au décours d'un passage en RCP, entre le 1er janvier 2010 et le 1er septembre 2016 ont été inclus. Les critères de conformité de prise en charge ont été établis en utilisant le dernier référentiel ESMO 2014, permettant de distinguer deux groupes, « conforme » et « non conforme » aux recommandations. Une première analyse comparative a été faite entre les deux groupes toutes lésions confondues. Puis une seconde uniquement sur les sarcomes.
Résultats
Au total, 445 patients présentant une lésion des tissus mous ont été inclus, 344 cas ont été traités selon les recommandations de l'ESMO, soit un taux de conformité de 77,3 %% (IC95 % : 73,4 %, 81,2 %). La conformité était meilleure pour le centre de référence que pour les structures périphériques (p < 0,001), avec des taux de conformité respectivement de 88,7 % et 51,6 %. Sur les 247 sarcomes, nous retrouvions un taux de résection R0 meilleur en cas de dossiers conformes 55 % contre 18 % (p < 0,001). Les taux de R1 étaient de 34 % contre 56 % et R2 de 11 contre 26 %. La survie n'était pas liée de manière significative à l'observance des recommandations dans l'analyse univariée. Après ajustement sur les facteurs pronostiques potentiels, en analyse multivariée, les résultats étaient similaires.
Conclusion
Le respect des recommandations de l'ESMO, permet d'améliorer la qualité de l'exérèse chirurgicale des sarcomes et évite les gestes chirurgicaux inappropriés.
Summary
Introduction
Despite regular recommendations issued by the European Society for Medical Oncology (ESMO), patients faced still too often inadequate care with a direct influence on prognosis.
Methods
A retrospective study was carried out at the Competence center in Lorraine Area. Patients registered in the NetSarc database between 1st, 2010 and September 1st, 2016 were included. Compliance criteria were established using the latest ESMO 2014 referential. Two groups "conforming" and "non conforming" were analyzed. A first analyze about all of the soft tissue lesion and a second only about sarcomas.
Results
In total, 445 patients were eligible, 344 cases were treated according to the ESMO guidelines, giving a 77.3% conformity rate (95% CI: 73.4%, 81.2%). Compliance was better for the competence center than district hospitals (P < 0.001), with compliance rates of 88.7%, and 51.6%, respectively. Among the 247 sarcomas, we found a R0 resection rate better according to the ESMO guideline, 55% against 18% (P < 0.001). R1 rates were 34% vs. 56% and R2 11 vs. 26% disease free survival was not related significantly to the observance of recommendations in the univariate analysis. After adjustment on potential DFS prognostic factors, in the multivariate analysis, the results were similar.
Conclusion
Compliance with the ESMO guidelines, through appropriate management, improves the quality of surgical excision for sarcomas and avoids non-corresponding surgical gestures.

From ontic structural realism to metaphysical coherentism
Abstract
The present paper argues that the typical structuralist claims according to which invariances, symmetries and the like are fundamental – especially in physics – should not be understood in terms of physical relations being fundamental. Rather, they should be understood in terms of 'metaphysical coherentism' - the idea that object-like parts of reality exhibit symmetric relations of ontological dependence. The view is developed in some detail, in particular by showing that i) symmetric ontological dependence does not necessarily lead to uninformative metaphysical explanations, and ii) metaphysical coherentism strikes the best balance between the requirements of naturalism and those of theoretical consistency – especially in view of the difficulties that structuralists seem to have in accounting for all state-independent properties of particles in relational terms. On this basis, the coherentist picture is applied to the interpretation of the quantum domain, and contrasted with extant varieties of structuralism, of both the eliminative and the non-eliminative sort, and holism.
