Duty of Candour legislation in post-colonoscopy colorectal cancer: a prospective cohort study.

Background: This study investigated the application of Duty of Candour (DoC) legislation in the context of post-colonoscopy colorectal cancers (PCCRCs). DoC mandates transparent disclosure of notifiable safety incidents to patients in the English National Health Service, including incidences leading to severe or moderate harm. This study aimed to analyze the application of DoC in PCCRCs, improve understanding of the legislation, and identify challenges in DoC implementation.

Functionalization of Electrospun Polycaprolactone Scaffolds with Matrix-Binding Osteocyte-Derived Extracellular Vesicles Promotes Osteoblastic Differentiation and Mineralization.

Synthetic polymeric materials have demonstrated great promise for bone tissue engineering based on their compatibility with a wide array of scaffold-manufacturing techniques, but are limited in terms of the bioactivity when compared to naturally occurring materials. To enhance the regenerative properties of these materials, they are commonly functionalised with bioactive factors to guide growth within the developing tissue. Extracellular matrix vesicles (EVs) play an important role in facilitating endochondral ossification during long bone development and have recently emerged as important mediators of cell-cell communication coordinating bone regeneration, and thus represent an ideal target to enhance the regenerative properties of synthetic scaffolds.

Ryanodine receptor calcium release channels in trophoblasts and their role in cell migration.

Trophoblasts are specialized epithelial cells of the placenta that are involved in invasion, communication and the exchange of materials between the mother and fetus. Cytoplasmic Ca ([Ca]) plays critical roles in regulating such processes in other cell types, but relatively little is known about the mechanisms that control this second messenger in trophoblasts. In the current study, the presence of RyRs and their accessory proteins in placental tissues and in the BeWo choriocarcinoma, a model trophoblast cell-line, were examined using immunohistochemistry and Western immunoblotting.

Specialist mental health consultation for depression in Australian aged care residents with dementia: a cluster randomized trial.

Objective: This cluster randomized controlled trial sought to determine whether multidisciplinary specialist mental health consultation was more effective than care as usual in treating the depression of aged care residents with dementia.

Methods: Three hundred and eighty nine aged care residents were screened for dementia and major depression. Forty four were ultimately included in the intervention sample, selected from 20 aged care facilities located in Melbourne, Australia.

Changes to psychotropic medications in the six months after admission to nursing homes in Melbourne, Australia.

Background: Nursing home residents are often prescribed large numbers of psychotropic medications. Previous studies suggest that antipsychotic medications are often unnecessary and can be withdrawn without ill effects. Depression, in contrast, is believed to be under-recognized and under-treated.
