Recent studies have successfully demonstrated the use of deep-learning algorithms for dermatologist-level classification suspicious lesions by excessive proprietary image databases and limited numbers dermatologists. For first time, performance a algorithm trained open-source images exclusively is compared to large number dermatologists covering all levels within clinical hierarchy.We used methods from enhanced deep learning train convolutional neural network (CNN) with 12,378 dermoscopic...

In light of the SARS-CoV-2 pandemic, protecting vulnerable groups has become a high priority. Persons at risk severe disease, for example, those receiving immunosuppressive therapies chronic inflammatory cdiseases (CIDs), are prioritised vaccination. However, data concerning generation protective antibody titres in immunosuppressed patients scarce. Additionally, mRNA vaccines represent new vaccine technology leading to increased insecurity especially with CID.Here we present first time, on...

The use of monoclonal antibodies has changed the treatment several immune-mediated inflammatory diseases, including psoriasis. However, these large proteins must be administered by injection. JNJ-77242113 is a novel, orally interleukin-23-receptor antagonist peptide that selectively blocks interleukin-23 signaling and downstream cytokine production.

Rare variants in the genes IL36RN, CARD14 and AP1S3 have been identified to cause or contribute pustular skin diseases, primarily generalized psoriasis (GPP).To better understand disease relevance of these genes, we screened our cohorts patients with diseases [primarily GPP palmoplantar (PPP)] for coding changes three genes. Carriers single heterozygous IL36RN mutations were a second mutation IL36RN.Coding exons sequenced 67 - 61 GPP, two acute exanthematous pustulosis four acrodermatitis...

Abstract Background Interleukin (IL)-13 is a key driver of inflammation and barrier dysfunction in atopic dermatitis (AD). While there robust evidence that tralokinumab – monoclonal antibody neutralizes IL-13 reduces clinical disease activity, less known about its effects on function.

Abstract: White adipose tissue is known to be involved in numerous physiological processes such as insulin‐mediated functions, lipid and glucose metabolism, vascular changes coagulation. These are mainly mediated by adipokines that secreted either from adipocytes or cells of the stromal‐vascular fraction tissue. In obesity, a shift production can mediate development associated diseases, metabolic syndrome, complications, artherosclerosis, myocardial infarction stroke, which comorbidities...

Abstract Psoriasis is a common, debilitating immune-mediated skin disease. Genetic studies have identified biological mechanisms of psoriasis risk, including those targeted by effective therapies. However, the genetic liability to not fully explained variation at robustly risk loci.

Recently, it has been questioned whether vaccination of patients with inflammatory (auto)immune diseases under anti-tumor necrosis factor (TNF) treatment leads to impaired vaccine-induced immune responses and protection against breakthrough infections. However, the effects TNF blockade on short- long-term after repeated remain unclear. Vaccination studies have shown that initial short-term IgG antibodies (Abs) carry highly galactosylated sialylated Fc glycans, whilst Abs low levels...
