Circular wood use can accelerate global decarbonisation but requires cross-sectoral coordination.

Predominantly linear use of wood curtails the potential climate-change mitigation contribution of forestry value-chains. Using lifecycle assessment, we show that more cascading and especially circular uses of wood can provide immediate and sustained mitigation by reducing demand for virgin wood, which increases forest carbon sequestration and storage, and benefits from substitution for fossil-fuel derived products, reducing net greenhouse gas emissions. By United Kingdom example, the circular approach of recycling medium-density fibreboard delivers 75% more cumulative climate-change mitigation by 2050, compared with business-as-usual.

Deconstructing the Trauma-Altered Identity of Black Men.

Multiple and continuous traumatic events experienced by Black men impose altering effects on their identities, and their mentalization and presentation of themselves in society. However, the unique dynamics of the impact of trauma in shaping Black men's identities are not well understood, because their experiences with trauma are not well documented. This paper is a secondary analysis of the qualitative component of a mixed method study that explored trauma, social support, and resilience among 103 racialized youth survivors of gun violence in Toronto, Canada.

Drug delivery of zinc to Barrett's metaplasia by oral administration to Barrett's esophagus patients.

Background: Delivery of a pharmacologically effective drug dosage to a target tissue is critical. Barrett's epithelia are a unique challenge for drug delivery of orally administered zinc due to rapid transit down the esophageal lumen, incomplete absorptive differentiation of these epithelia, and the use of proton-pump inhibitor drugs abrogating intestinal uptake of supplemental zinc.

Methods: Barrett's esophagus patients were administered oral zinc gluconate (26 mg zinc twice daily) for 14 days prior to biopsy procurement.

Bacteremia due to clostridium difficile: case report and review of the literature.

Objective: The purpose of this study is to report a case of C. difficile bacteremia in a Crohn's disease patient and to review the literature on previously reported cases.

Methods: Searches of MEDLINE and PubMed databases were made.
