Laboratory changes during dupilumab treatment for atopic dermatitis.

Introduction: Dupilumab is an IL-4 / IL-13 inhibitor monoclonal antibody approved for the treatment of moderate-to-severe atopic dermatitis (AD) with remarkable safety and efficacy profiles. However, former studies have reported an increase in serum eosinophils during treatment, with undetermined clinical significance.

The Objective: of this study is to evaluate changes in blood eosinophils and other laboratory parameters while on dupilumab.

Bowel-Associated Dermatosis-Arthritis Syndrome: A Report of a Rare Case.

A 31-year-old female, recently discharged after improvement of an exacerbation of ulcerative colitis, returned to the hospital due to fever, polyarthralgia affecting the knees and ankles, and symmetric violaceous papulopustular lesions on her arms, trunk, and lower limbs. Histological examination revealed superficial dermal edema and perivascular invasion of neutrophils with leukocytoclasia, consistent with neutrophilic dermatosis, and a diagnosis of bowel-associated dermatosis-arthritis syndrome (BADAS) was established. BADAS is a rare, characteristic neutrophilic dermatosis and arthritis mainly associated with intestinal inflammatory disease due to bacterial overgrowthand subsequent immune complex formation and deposition.

Using systems mapping to understand the constraints and enablers of solutions to plastic pollution.

Plastic pollution is now considered globally ubiquitous, irreversible, and a planetary boundary threat. Solutions are urgently needed but their development and application are hampered by the complexity and scale of the issue. System dynamics is a technique used to understand complex behaviours of systems through model building and is useful for conceptualising the relationships between various interacting, dynamic factors, and identifying potential intervention points within the system where specific policies or innovations might have the greatest impact or meet with the greatest resistance.
