Psoriasis and Psoriatic Arthritis Have a Major Impact on Quality of Life and Depressive Symptoms: A Cross-Sectional Study of 300 Patients.

Introduction: Psoriasis (Pso) and psoriatic arthritis (PsA) can reduce the quality of life (QoL) and are known to be associated with depression. Within this study, we aimed to assess the burden of disease, functional capacity, quality of life, and depressive symptoms and identify factors predicting functional impairment and depression in patients with psoriatic disease.

Methods: A cross-sectional survey was conducted in a cohort of 300 patients with psoriatic disease including 150 patients from a university hospital dermatology outpatient clinic and 150 patients from a university hospital rheumatology outpatient clinic.

Modeling MyD88 Deficiency Provides New Insights in Its Function.

Inherited defects in MyD88 and IRAK4, two regulators in Toll-like receptor (TLR) signaling, are clinically highly relevant, but still incompletely understood. MyD88- and IRAK4-deficient patients are exceedingly susceptible to a narrow spectrum of pathogens, with ∼50% lethality in the first years of life. To better understand the underlying molecular and cellular characteristics that determine disease progression, we aimed at modeling the cellular response to pathogens .

COVID-19 in a Severely Immunosuppressed Patient With Life-Threatening Eosinophilic Granulomatosis With Polyangiitis.

Immunosuppressive therapies increase the susceptibility of patients to infections. The current pandemic with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) compels clinicians to develop recommendations for successful clinical management and surveillance of immunocompromised patients at high risk for severe disease progression. With only few case studies published on SARS-CoV-2 infection in patients with rheumatic diseases, we report a 25-year-old male who developed moderate coronavirus disease 2019 (COVID-19) with fever, mild dyspnea, and no major complications despite having received high-dose prednisolone, cyclophosphamide, and rituximab for the treatment of highly active, life-threatening eosinophilic granulomatosis with polyangiitis (EGPA).

A chemical-genetic screen reveals a mechanism of resistance to PI3K inhibitors in cancer.

Linking the molecular aberrations of cancer to drug responses could guide treatment choice and identify new therapeutic applications. However, there has been no systematic approach for analyzing gene-drug interactions in human cells. Here we establish a multiplexed assay to study the cellular fitness of a panel of engineered isogenic cancer cells in response to a collection of drugs, enabling the systematic analysis of thousands of gene-drug interactions.

Cardiac glycosides induce cell death in human cells by inhibiting general protein synthesis.

Background: Cardiac glycosides are Na(+)/K(+)-pump inhibitors widely used to treat heart failure. They are also highly cytotoxic, and studies have suggested specific anti-tumor activity leading to current clinical trials in cancer patients. However, a definitive demonstration of this putative anti-cancer activity and the underlying molecular mechanism has remained elusive.
