Background: The neural basis of memory aging remains elusive. The default mode network (DMN) supports memory encoding and retrieval, and its connectivity decreases in aging. Young adults with larger differences in resting-state functional connectivity (rsFC) between higher-order DMN and lower-order sensory/motor network (SMN) have better cognition and memory.

Using vessels of opportunity for determining important habitats of bottlenose dolphins in Port Phillip Bay, south-eastern Australia.

Understanding species' critical habitat requirements is crucial for effective conservation and management. However, such information can be challenging to obtain, particularly for highly mobile, wide-ranging species such as cetaceans. In the absence of systematic surveys, alternative economically viable methods are needed, such as the use of data collected from platforms of opportunity, and modelling techniques to predict species distribution in un-surveyed areas.

Longitudinal relationships between Aβ and tau to executive function and memory in cognitively normal older adults.

The early accumulation of AD pathology such as Aβ and tau in cognitively normal older people is predictive of cognitive decline, but it has been difficult to dissociate the cognitive effects of these two proteins. Early Aβ and tau target distinct brain regions that have different functional roles. Here, we assessed specific longitudinal pathology-cognition associations in seventy-six cognitively normal older adults from the Berkeley Aging Cohort Study who underwent longitudinal PiB PET, FTP PET, and cognitive assessments.

A qualitative study exploring the experiences of advanced clinical practitioner training in emergency care in the South West of England, United Kingdom.

Background: Attempting to improve emergency care (EC) advanced clinical practitioner (ACP) training, Health Education England (HEE) South West (SW) implemented a pilot, whereby emergency departments (ED) were provided with enhanced funding and support to help ED consultants deliver teaching and supervision to EC ACPs to ensure more timely completion of EC ACP training compared with previous cohorts training in the region.We explored the experiences of trainee EC ACPs and consultant EC ACP leads working in EDs, which had implemented the new regional pilot.

Methods: We used a qualitative design to conduct semi-structured interviews with trainee EC ACPs and consultant EC ACP leads across five EDs that had implemented the HEE SW pilot.

Associations between regional blood-brain barrier permeability, aging, and Alzheimer's disease biomarkers in cognitively normal older adults.

Background: Increased blood-brain barrier permeability (BBBp) has been hypothesized as a feature of aging that may lead to the development of Alzheimer's disease (AD). We sought to identify the brain regions most vulnerable to greater BBBp during aging and examine their regional relationship with neuroimaging biomarkers of AD.

Methods: We studied 31 cognitively normal older adults (OA) and 10 young adults (YA) from the Berkeley Aging Cohort Study (BACS).

Understanding health service utilisation patterns for care home residents during the COVID-19 pandemic using routinely collected healthcare data.

Background: Healthcare in care homes during the COVID-19 pandemic required a balance, providing treatment while minimising exposure risk. Policy for how residents should receive care changed rapidly throughout the pandemic. A lack of accessible data on care home residents over this time meant policy decisions were difficult to make and verify.

'In the shower crying…but we came back in the following day and did it all again'. Distress and resilience in care home staff during the COVID-19 pandemic- A qualitative interview study.

Background: Care homes (long-term care facilities) were profoundly impacted early in the COVID-19 pandemic, both in terms of resident mortality and restrictions for infection control. This study investigated the impact on the emotional well-being of care home staff of challenges faced at this time, and the strategies used to manage them.

Methods: Semi-structured interviews conducted October 2020-June 2021 with care home staff and health service staff working with them explored the impact of the early waves of the COVID-19 pandemic (March 2020-June 2021).

Exploring advanced clinical practitioner perspectives on training, role identity and competence: a qualitative study.

Background: Advanced Clinical Practitioners (ACPs) are a new role that have been established to address gaps and support the existing medical workforce in an effort to help reduce increasing pressures on NHS services. ACPs have the potential to practice at a similar level to mid-grade medical staff, for example independently undertaking assessments, requesting and interpreting investigations, and diagnosing and discharging patients. These roles have been shown to improve both service outcomes and quality of patient care.

The impact of digital technology in care homes on unplanned secondary care usage and associated costs.

Background: A substantial number of Emergency Department (ED) attendances by care home residents are potentially avoidable. Health Call Digital Care Homes is an app-based technology that aims to streamline residents' care by recording their observations such as vital parameters electronically. Observations are triaged by remote clinical staff.

What impact would reducing low-acuity attendance have on emergency department length of stay? A discrete event simulation modelling study.

Background: Long waiting times in the ED have been shown to cause negative outcomes for patients. This study aims to assess the effect in reducing length of stay of (1) preventing low-acuity attenders from attending the ED and (2) diverting low-acuity attenders at triage to a colocated general practice (GP) service.

Methods: Discrete event simulation was used to model a large urban teaching hospital in the UK, as a case study, with a colocated GP service.

Delivery of public health interventions by the ambulance sector: a scoping review.

Background: With millions of unscheduled patient contacts every year and increasing call outs clustered around the most deprived communities, it is clear the ambulance sector could have a role to play in improving population health. However, the application and value of a public health approach within the ambulance sector has not been comprehensively explored. A scoping review was undertaken to explore the role of the ambulance sector in the delivery of public health interventions and what impact this has on population health and ambulance sector outcomes.

Identifying models of care to improve outcomes for older people with urgent care needs: a mixed methods approach to develop a system dynamics model.

Background: We aimed to understand urgent and emergency care pathways for older people and develop a decision support tool using a mixed methods study design.

Objective(s), Study Design, Settings And Participants: Work package 1 identified best practice through a review of reviews, patient, carer and professional interviews. Work package 2 involved qualitative case studies of selected urgent and emergency care pathways in the Yorkshire and Humber region.

Navigating data governance associated with real-world data for public benefit: an overview in the UK and future considerations.

Real-world data encompass data primarily captured for the provision or operation of services, for example, electronic health records for direct care purposes, but which may have secondary uses for informing research or commissioning. Public benefit is potentially forfeited by the underutilisation of real-world data for secondary uses, in part due to risk aversion when faced with the prospect of navigating necessary and important data governance processes. Such processes can be perceived as complex, daunting, time-consuming and exposing organisations to risk.

Using ecotourism boats for estimating the abundance of a bottlenose dolphin population in south-eastern Australia.

It is challenging to collect robust, long-term datasets to properly monitor the viability and social structure of large, long-lived animals, especially marine mammals. The present study used a unique long-term dataset to investigate the population parameters and social structure of a poorly studied population of bottlenose dolphins (Tursiops sp.) in southern Port Phillip Bay, south-eastern Australia.

Use of urgent, emergency and acute care by mental health service users: A record-level cohort study.

Background: People with serious mental illness experience worse physical health and greater mortality than the general population. Crude rates of A&E attendance and acute hospital admission are higher in people with serious mental illness than other hospital users. We aimed to further these findings by undertaking a standardised comparison of urgent and emergency care pathway use among users of mental health services and the general population.
