Trends in certifications of overall vision impairment and that due to diabetic retinopathy/maculopathy in England and Wales, 2009/2010 to 2019/2020: a retrospective database analysis.

Objectives: This study aims to report the trends in the certification of both sight impairment (SI) and severe sight impairment (SSI) in England and Wales during the period of 2010 to 2020, prior to the COVID-19 pandemic. The focus is on diabetic retinopathy/maculopathy as the key causative factor.

Design: Retrospective database analysis.

A foundation model of transcription across human cell types.

Transcriptional regulation, which involves a complex interplay between regulatory sequences and proteins, directs all biological processes. Computational models of transcription lack generalizability to accurately extrapolate to unseen cell types and conditions. Here we introduce GET (general expression transformer), an interpretable foundation model designed to uncover regulatory grammars across 213 human fetal and adult cell types.

Understanding Disenfranchised Grief in a Post-COVID-19 World-A Pilot Study of Advanced Practice Registered Nurses in Palliative Care.

Disenfranchised grief is a form of grief that remains unacknowledged and unsupported. Building on Doka's foundational concept of disenfranchised grief, the guiding framework for this pilot project was the Knowledge to Action framework. This study is a quantitative cross-sectional web-based survey, which included a validated questionnaire: the Witnessing Disenfranchised Grief Scale.

Incorporating Economic Evidence in Clinical Guidelines: A Framework From the Clinical Guidelines Committee of the American College of Physicians.

In recognition of accelerating health care spending and alignment with the American College of Physicians (ACP) principles of promoting high-value care, the ACP Clinical Guidelines Committee (CGC) developed a framework to standardize its approach to identifying, appraising, and considering economic evidence in the development of ACP clinical guidelines. This article presents the CGC's process for incorporating economic evidence, which encompasses cost-effectiveness analyses, economic outcomes in randomized controlled trials, and resource utilization (intervention cost) data. Economic evidence is one component of ACP recommendations.

Bone marrow niches orchestrate stem-cell hierarchy and immune tolerance.

Stem cells reside in specialized microenvironments, termed niches, at several different locations in tissues. The differential functions of heterogeneous stem cells and niches are important given the increasing clinical applications of stem-cell transplantation and immunotherapy. Whether hierarchical structures among stem cells at distinct niches exist and further control aspects of immune tolerance is unknown.
