Structure-function analysis of tight junction-directed permeation enhancer PIP250.

The intestinal paracellular route of absorption is modulated via tight junction (TJ) structures located at the apical neck of polarized intestinal epithelial cells to restrict solute movement through the intercellular space between them. Tight junctions open or close in response to changes in the phosphorylation status of light chain (MLC) at position Ser-19. This phosphorylation event is primarily controlled by MLC kinase (MLCK) and MLC phosphatase (MLCP), the latter being a holoenzyme that involves interaction between protein phosphatase 1 (PP1) and myosin targeting protein 1 (MYPT1).

Hydrogel formats to model potential drug interactions occurring at the subcutaneous injection site.

We have previously developed an in vitro instrument, termed subcutaneous injection site simulator (SCISSOR), that can be used to monitor release properties of an active pharmaceutical ingredient (API) and formulation components of a medicine designed for SC injection. Initial studies to validate the SCISSOR instrument applications used a simple hyaluronic acid (HA) hydrogel to monitor early release events. We now report a type of cross-linked HA that can, when combined with HA, provide a hydrogel (HA-XR) with optical clarity and rheological properties that remain stable for at least 6 days.

How do quantitative studies involving people with dementia report experiences of standardised data collection? A narrative synthesis of NIHR published studies.

Background: People with dementia are routinely included as research participants in trials and other quantitative studies in which they are invited to respond to standardised measures. This paper reviews the reporting of standardised data collection from people with dementia in reports published in the National Institute for Health and Care Research (NIHR) Journals Library. The aim was to understand how the administration of standardised, self-report measures with people with dementia is reported in NIHR monographs and what could be learnt from this about the feasibility and acceptability of data collection approaches for future studies.

Social care planning and provision for people with young onset dementia and their families: Protocol for the DYNAMIC study.

Background: Social care is vital to quality of life for people with young onset dementia and their families. Yet care is hugely variable, frequently lacking and poorly coordinated. We aim to establish current practice in English social care for people with young onset dementia and co-produce evidence-based recommendations and resources for improvement.

Long-term impact of the COVID-19 pandemic on the quality of life of people with dementia and their family carers.

Introduction: Few studies have longitudinally mapped quality of life (QoL) trajectories of newly diagnosed people with dementia and their carers, particularly during coronavirus disease-2019 (COVID-19).

Methods: In a UK cohort study, 261 newly diagnosed people with dementia and 206 family carers were assessed prior to the pandemic (July 2019-March 2020), followed up after the first lockdown (July-October 2020) and then again a year and 2 years later. Latent growth curve modelling examined the level and change of QoL over the four time-points using dementia-specific QoL measures (DEMQOL and C-DEMQOL).

Standardised data collection from people with dementia over the telephone: A qualitative study of the experience of DETERMIND programme researchers in a pandemic.

There is a notable lack of evidence on what constitutes good practice in remote quantitative data collection from research participants with dementia. During the COVID-19 pandemic face-to-face research became problematic, especially where participants were older and more at risk of infection. The DETERMIND-C19 study, a large cohort study of people with dementia, switched to telephone data collection over this period.

Emotion-focused dyadic coping styles used by family carers of people with dementia during the COVID-19 pandemic.

Emotional wellbeing of family carers and people with dementia is associated with not only how each individual copes with stress and conflict, but also by how they cope together. Finding ways to positively cope together was particularly important during COVID-19 lockdown restrictions, when other avenues of emotional support were less available. We explored how carers experienced and used emotion-focused dyadic coping styles during the COVID-19 pandemic.

Using digital technologies to facilitate social inclusion during the COVID-19 pandemic: Experiences of co-resident and non-co-resident family carers of people with dementia from DETERMIND-C19.

Background: The COVID-19 pandemic triggered rapid and unprecedented changes in the use of digital technologies to support people's social inclusion. We examined whether and how co-resident and non-co-resident family carers of people with dementia engaged with digital technologies during this period.

Methods: Throughout November 2020-February 2021, we interviewed 42 family carers of people with dementia from our DETERMIND-C19 cohort.

'Pushing back': People newly diagnosed with dementia and their experiences of the Covid-19 pandemic restrictions in England.

Background And Objectives: Research into people with dementia's experiences of the Covid-19 pandemic has tended to focus on vulnerabilities and negative outcomes, with the risk of reproducing a discourse in which people with dementia are positioned as passive. Informed by concepts positioning people with dementia as 'active social agents', we aimed to identify the pandemic-related challenges faced by people recently diagnosed with dementia and examine the ways in which they actively coped with, and adapted to, these challenges.

Research Design And Methods: In-depth interviews with 21 people recently diagnosed with dementia, recruited through an existing national cohort.

Social care causes of delayed transfer of care (DTOC) from hospital for older people: Unpicking the nuances of 'provider capacity' and 'patient choice'.

Unnecessarily prolonged stays in hospitals can have negative impacts on patients and present avoidable costs to health and social care systems. This paper presents the qualitative findings of a multi-methods study of the social care causes of delayed transfers of care (DTOC) for older people in England. The quantitative strand of this study found that DTOC are significantly affected by homecare supply.

A cohort study of the impact of COVID-19 on the quality of life of people newly diagnosed with dementia and their family carers.

Introduction: COVID-19 has impacted people with dementia and their family carers, yet little is known about effects on overall quality of life.

Methods: In a UK cohort study, pre- and post-pandemic data were collected from 114 carers and 93 recently diagnosed people with dementia. Latent growth curve modeling examined change in quality of life.

How local partnerships to improve urgent and emergency care have impacted delayed transfers of care from hospitals in England: an analysis based on a synthetic control estimation method.

Objectives: Patients should be discharged from hospital when they are medically fit. However, discharges are often delayed for non-medical reasons including access to social care. One aim of local health and social care partnerships to improve urgent and emergency care in England (known as urgent and emergency care (UEC) vanguards) was to improve integration of health and social care, which could lead to fewer delays.

The influence of home care supply on delayed discharges from hospital in England.

Background: Delayed transfers of care (DTOC) of patients from hospital to alternative care settings are a longstanding problem in England and elsewhere, having negative implications for patient outcomes and costs to health and social care systems. In England, a large proportion of DTOC are attributed to a delay in receiving suitable home care. We estimated the relationship between home care supply and delayed discharges in England from 2011 to 2016.

Specialist nursing case management support for carers of people with dementia: A qualitative study comparing experiences of carers with and without Admiral Nursing.

Carers of people with dementia can experience reduced health and well-being, but little is known about how best to support them. There is some evidence to suggest that case management may improve outcomes for carers but less evidence about the features of case management services that can effectively support carers of people with dementia. Admiral Nursing operates a case management approach staffed by specialist nurses and is the only service of its kind in the United Kingdom dedicated to helping people with dementia and their carers.

Using a systematic review to uncover theory and outcomes for a complex intervention in health and social care: a worked example using life story work for people with dementia.

Objectives: Life story work involves gathering information about a person, their history and interests, and producing a tangible output, usually a book. It is used increasingly in dementia care. However, theory about if, how, and why it affects outcomes is poorly developed, making the choice of evaluation methods and appropriate outcomes difficult.

Investigating the economic case of a service to support carers of people with dementia: A cross-sectional survey-based feasibility study in England.

Carers contribute essential support to enable people with dementia to continue living within the community. Admiral Nurses provide specialist dementia support for carers of people with dementia, including offering expert emotional support and guidance, and work to join up different parts of the health and social care system to address needs in a co-ordinated way. The cost-effectiveness of this service is not clear.

Comparison of emergency physiotherapy practitioner prescribers versus existing emergency department prescribers for musculoskeletal injuries.

Objective: The scope of selected emergency physiotherapy practitioners (EPP) in this Australian non-tertiary ED has recently extended to include the prescription of a limited drug formulary, including paracetamol, some NSAIDs and opioids, an anti-emetic, a benzodiazepine and nitrous oxide. Although there are large-scale studies investigating prescription errors made by doctors, there is a lack of data on prescribing practices of physiotherapists in the ED setting. The aim of present study is to compare the prescribing practices of EPP to their medical and nursing colleagues within the setting of treating musculoskeletal injuries in the ED.

Good practice in social care: the views of people with severe and complex needs and those who support them.

This paper reports findings drawn from a study of good practice in English social care for adults with disability and older people with severe and complex needs. People with severe and complex needs are a relatively small proportion of adult social care service users, but they are growing in numbers and have resource-intensive needs. The study involved qualitative research with adults with disability and older people with severe and complex needs, family carers and members of specialist organisations (n = 67), focusing on the features of social care services they considered to be good practice.

Good practice in social care for disabled adults and older people with severe and complex needs: evidence from a scoping review.

This article reports findings from a scoping review of the literature on good practice in social care for disabled adults and older people with severe and complex needs. Scoping reviews differ from systematic reviews, in that they aim to rapidly map relevant literature across an area of interest. This review formed part of a larger study to identify social care service models with characteristics desired by people with severe and complex needs and scope the evidence of effectiveness.

Arsenite elicits anomalous sulfur starvation responses in barley.

Treatment of barley (Hordeum vulgare) seedlings with arsenite (AsIII) rapidly induced physiological and transcriptional changes characteristic of sulfur deficiency, even in plants replete with sulfur. AsIII and sulfur deficiency induced 5- to 20-fold increases in the three genes responsible for sulfate reduction. Both treatments also caused up-regulation of a sulfate transporter, but only in the case of sulfur deficiency was there an increase in sulfate influx.
