Views about Euthanasia and Dementia: Exploring Perceptions Utilising Evidence from the Mass Observation Archive.

This paper contributes to the ongoing discussion in the United Kingdom regarding euthanasia and assisted dying, using data specifically related to individuals with dementia. A qualitative approach was taken with data captured via a set of written questions in the form of a Mass Observation Archive Directive. The respondents, known as Observers, provided written responses; there was no limit to the length of the responses and the Observers were able to provide as much or as little detail as they chose. The data were analysed thematically utilising NVivo software. One-hundred and seven responses were received, representing a range of beliefs, and with opinions regarding euthanasia and dementia with pro, anti, and uncertain views being expressed. Five main themes emerged during our data analysis: capacity, legislation, agency and personal philosophies, disquietude, and incumbrance. Consistent with previous research capturing public views regarding euthanasia and assisted dying for people with dementia, the findings suggest policy makers may wish to consult the British public regarding legislation regarding euthanasia and dementia.

The acceptability of the Fire and Rescue Service working with primary care to improve identification of mental health problems in older adults. A mixed-method qualitative study.

BACKGROUND: Mental ill-health in older adults (aged 60 years and over) is often underdiagnosed and undertreated. Older adults are less likely to access mental health services owing to perceived stigma and fear of being a burden. Non-traditional providers of health care, such as the Fire and Rescue Services (FRS), provide a possible solution to facilitate early detection of problems and help-seeking among older adults, especially in the context of pressured statutory services. AIM: To examine whether and how FRS Home Fire Safety Visits (HFSV) could be optimised to include detection and signposting for mental health problems - particularly anxiety and depression - in older adults. DESIGN & SETTING: This mixed-method qualitative study took place in the West Midlands, UK in 2022. METHOD: This study involved focus groups (n = 24) and interviews with FRS staff (n = 4) to develop an in-depth contextual understanding of he acceptability and feasibility of expanding HFSV to include identification of anxiety and depression. RESULTS: FRS staff were open to expanding their HFSVs to include mental health, provided they had sufficient training and support from partner agencies in primary and social care settings to accept referrals for service users presenting with symptoms of anxiety and/or depression. CONCLUSION: The positive reputation of FRS staff and engagement with older adults suggests that HFSV could support the detection of anxiety and depression in older adults, and appropriate signposting to other services including primary care.

Student Nurses Undertaking Acute Hospital Paid Placements during COVID-19: Rationale for Opting-In? A Qualitative Inquiry.

The research aim was to evaluate the rationale of undergraduate final-year student nurses to undertake paid clinical placements during COVID-19 (Wave 1). The nursing profession reacted innovatively to meet demands placed on the National Health Service during COVID-19. Temporary changes to professional regulation enabled final-year United Kingdom nursing students to voluntarily undertake paid placements in the National Health Service. Neither full-time employees nor full-time students, volunteers undertook a unique hybrid role bolstering the front-line health workforce. Using reflective qualitative inquiry, 17 volunteers evaluated reasoning for entering practice in acute hospitals. Online surveys based around the UK Nursing and Midwifery Council Competency Framework (NMC 2012) were completed weekly for 6 weeks. Data were thematically analysed. Six themes were identified, including sense of duty, and opting-in or out. These highlighted the importance of collaboration and the tripartite relationship between University, host and student during placement, and the influence of these on the learning experience. Several significant insights emerged for nurse education and curricula during pandemics related to patient safety, safety climate and governance. The insights were used to develop a "Student Nurses Placement Framework" with recommendations for Pre-During-Post placement, offering a guide for future nursing workforce recruitment and retention.

Progress toward multiplexed sample-to-result detection in low resource settings using microfluidic immunoassay cards.

In many low resource settings multiple diseases are endemic. There is a need for appropriate multi-analyte diagnostics capable of differentiating between diseases that cause similar clinical symptoms. The work presented here was part of a larger effort to develop a microfluidic point-of-care system, the DxBox, for sample-to-result differential diagnosis of infections that present with high rapid-onset fever. Here we describe a platform that detects disease-specific antigens and IgM antibodies. The disposable microfluidic cards are based on a flow-through membrane immunoassay carried out on porous nitrocellulose, which provides rapid diffusion for short assay times and a high surface area for visual detection of colored assay spots. Fluid motion and on-card valves were driven by a pneumatic system and we present designs for using pneumatic control to carry out assay functions. Pneumatic actuation, while having the potential advantage of inexpensive and robust hardware, introduced bubbles that interfered with fluidic control and affected assay results. The cards performed all sample preparation steps including plasma filtration from whole blood, sample and reagent aliquoting for the two parallel assays, sample dilution, and IgG removal for the IgM assays. We demonstrated the system for detection of the malarial pfHRPII antigen (spiked) and IgM antibodies to Salmonella Typhi LPS (patient plasma samples). All reagents were stored on card in dry form; only the sample and buffer were required to run the tests. Here we detail the development of this platform and discuss its strengths and weaknesses.

Microfluidics without pumps: reinventing the T-sensor and H-filter in paper networks.

Conventional microfluidic devices typically require highly precise pumps or pneumatic control systems, which add considerable cost and the requirement for power. These restrictions have limited the adoption of microfluidic technologies for point-of-care applications. Paper networks provide an extremely low-cost and pumpless alternative to conventional microfluidic devices by generating fluid transport through capillarity. We revisit well-known microfluidic devices for hydrodynamic focusing, sized-based extraction of molecules from complex mixtures, micromixing, and dilution, and demonstrate that paper-based devices can replace their expensive conventional microfluidic counterparts.

Laboratory-scale protein striping system for patterning biomolecules onto paper-based immunochromatographic test strips.

A method for patterning narrow lines of biomolecules onto nitrocellulose membranes using laboratory syringe pumps is described. One syringe pump is used to drive the biomolecule solution through a needle, while another modified syringe pump acts as a one-dimensional translation stage, moving the needle across the membrane much like a pen. This method consumes very small volumes of reagents, and is a viable option for laboratory-scale fabrication and prototyping of point-of-care rapid diagnostic test strips.

Enabling a microfluidic immunoassay for the developing world by integration of on-card dry reagent storage.

As part of an effort to create a point-of-care diagnostic system for the developing world, we present a microfluidic flow-through membrane immunoassay with on-card dry reagent storage. By preserving reagent function, the storage and reconstitution of anhydrous reagents enables the devices to remain viable in challenging, unregulated environmental conditions. The assay takes place on a disposable laminate card containing both a porous membrane patterned with capture molecules and a fibrous pad containing an anhydrous analyte label. To conduct the assay, the card is placed in an external pumping and imaging instrument capable of delivering sample and rehydrated reagent to the assay membrane at controlled flow rates to generate quantitative results. Using the malarial antigen Plasmodium falciparum histidine-rich protein II (PfHRP2) as a model, we demonstrate selection of dry storage conditions, characterization of reagent rehydration, and execution of an automated on-card assay. Gold-antibody conjugates dried in a variety of sugar matrices were shown to retain 80-96% of their activity after 60 days of storage at elevated temperatures, and the release profile of the reconstituted reagent was characterized under flow in microfluidic channels. The system gave a detection limit in the sub-nanomolar range in under nine minutes, showing the potential to expand into quantitative, multi-analyte analysis of human blood samples.
