Clinical Variant of Serpentine Supravenous Hyperpigmentation Following Subcutaneous Bortezomib Injection.

Introduction: Bortezomib is a reversible proteasome inhibitor that is a first-line chemotherapeutic agent for multiple myeloma. Bortezomib can be administered intravenously or subcutaneously with similar efficacy. Subcutaneous administration has fewer side effects.

Real-world mepolizumab treatment in patients with severe asthma decreased exacerbations, oral corticosteroid use, and healthcare resource utilization and costs over 4 years: a retrospective analysis.

Objective: Although the efficacy of mepolizumab in reducing exacerbations and oral corticosteroid (OCS) use in severe asthma is well-established, real-world long-term effectiveness data are limited. This study evaluated the real-world impact of mepolizumab treatment in patients with severe asthma over a 4-year follow-up period.

Methods: This was a retrospective cohort study of patients with asthma initiating mepolizumab (index date: first claim, November 2015-September 2019) using the Merative MarketScan Commercial and Medicare Databases.

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Sebaceous Carcinoma Arising in a Precursor Benign Sebaceoma: Rare Example Highlighting the Utility of Immunohistochemistry Including p53.

Reports of sebaceous carcinoma arising from a pre-existing benign precursor are extremely sparse in the literature. We describe a case in which there was clear transition between sebaceoma and sebaceous carcinoma, with a different pattern of p53 staining in each component.

Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.
