Piloting a minimum data set for older people living in care homes in England: a developmental study.

Background: We developed a prototype minimum data set (MDS) for English care homes, assessing feasibility of extracting data directly from digital care records (DCRs) with linkage to health and social care data.

Methods: Through stakeholder development workshops, literature reviews, surveys and public consultation, we developed an aspirational MDS. We identified ways to extract this from existing sources, including DCRs and routine health and social care datasets.

Public Involvement to Enhance Care Home Research; Collaboration on a Minimum Data Set for Care Homes.

Introduction: Information on care home residents in England is captured in numerous data sets (care home records, General Practitioner records, community nursing, etc.) but little of this information is currently analysed in a way that is useful for care providers, current or future residents and families or that realises the potential of data to enhance care provision. The DACHA study aimed to develop and test a minimum data set (MDS) which would bring together data that is useful to support and improve care and facilitate research.

Design, optimization, and inference of biphasic decay of infectious virus particles.

Virus population dynamics are driven by counter-balancing forces of production and loss. Whereas viral production arises from complex interactions with susceptible hosts, the loss of infectious virus particles is often approximated as a first-order kinetic process. As such, experimental protocols to measure infectious virus loss are not typically designed to identify non-exponential decay processes.

Erwinia phage Asesino is a nucleus-forming phage that lacks PhuZ.

As nucleus-forming phages become better characterized, understanding their unifying similarities and unique differences will help us understand how they occupy varied niches and infect diverse hosts. All identified nucleus-forming phages fall within the Chimalliviridae family and share a core genome of 68 unique genes including chimallin, the major nuclear shell protein. A well-studied but non-essential protein encoded by many nucleus-forming phages is PhuZ, a tubulin homolog which aids in capsid migration, nucleus rotation, and nucleus positioning.

Safety and Immunogenicity of SARS-CoV-2 Spike Receptor-Binding Domain andN-Terminal Domain mRNA Vaccine.

Background: mRNA-1283 is an investigational COVID-19 mRNA vaccine encoding the receptor-binding and N-terminal domains of the SARS-CoV-2 spike protein in contrast to the original mRNA-1273, which encodes the full-length spike protein.

Methods: A phase 2a, dose-ranging, observer-blind, randomized study (NCT05137236) conducted in adults (≥18 years) previously vaccinated with mRNA-1273 evaluated the safety and immunogenicity of a single dose of mRNA-1283 (2.5, 5, and 10 µg) and its bivalent formulation, mRNA-1283.
