Abstract
This paper discusses the risk of gross negligence manslaughter (GNM) and corporate manslaughter charges (CM) when clinicians use an artificially intelligent system's (AIS's) outputs in their practice. I identify the elements of these offenses within the context of the law of England and Wales and explore how they could be applied in a potential scenario where a patient's death has followed AIS use by a clinician. The risk of a conviction due to making an AIS-augmented workplace mistake highlights the non-trivial nature of AIS adoption in healthcare, and that the consequences of its use must be considered by all interested parties prior to AIS adoption.

Abstract
Background Borderline personality disorder (BPD) is a severe mental disorder that is characterised by a pervasive pattern of instability of interpersonal relationships, self-image, and mood as well as marked impulsivity. BPD has its peak incidence and prevalence from puberty through to emerging adulthood. BPD is a controversial diagnosis in young people. Commonly, young people with BPD are under-diagnosed, untreated, are not in employment or training and are estranged from their families. Yet, they have complex needs and are at high suicide risk. Aim To assess the feasibility of conducting a randomised controlled trial (f-RCT) of a BRIDGE, a brief intervention programme for young people (age 14-24) with BPD symptoms (sub-threshold or threshold) in a community sample from Scotland, UK. Method Forty young people (age 14-24) meeting criteria for BPD symptoms, will be randomised in a 1:1 ratio to receive either a) the BRIDGE intervention plus service-as-usual or b) service-as-usual alone. Follow up will be 12 weeks and 24 weeks post-intervention. The study is carried out between 2021 to 2024. Outcome The two primary outcomes of the MQ funded, BRIDGE project (f-RCT) are i. recruitment rates and ii. retention rates. The study will present the acceptability and appropriateness of our putative outcome measures for a future definitive randomised controlled trial (d-RCT). Impact Young people with BPD benefit from good clinical care and targeted intervention, however are regularly missed or mislabelled. The community based feasibility trial would provide initial evidence of variable needs of young people with complex needs, who maybe missed or excluded from services as they don't "fit" a model/diagnosis. Workable multi-agency service model proposed in the trial would be a major advance in understanding care pathways regardless of trial outcome.

Abstract
This article contributes to the ongoing debate about legal liability and responsibility for patient harm in scenarios where artificial intelligence (AI) is used in healthcare.We note that due to the structure of negligence liability in England and Wales, it is likely that clinicians would be held solely negligent for patient harms arising from software defects, even though AI algorithms will share the decision-making space with clinicians.Drawing on previous research, we argue that the traditional model of negligence liability for clinical malpractice cannot be relied upon to offer justice for clinicians and patients. There is a pressing need for law reform to consider the use of risk pooling, alongside detailed professional guidance for the use of AI in healthcare spaces.

Abstract
BACKGROUND The study of genetic variation as a factor influencing drug safety, efficacy, and effectiveness has brought about significant breakthroughs in understanding the clinical application of gene-drug interactions to better manage drug therapy. OBJECTIVE This study was designed to assess the feasibility of collecting buccal samples by general practitioners (GPs) at private practices in Singapore within a usual consultation, incorporating use of a pharmacogenetics-based medical decision support system to guide subsequent drug dosing. METHODS We used a prospective cohort study design, with GPs recruiting 189 patients between October 2020 and March 2021. The genotypes of 51 biallelic SNPs were determined using Illumina Infinium Global Screening Array. RESULTS Seven GPs from 6 private practices recruited and obtained buccal samples from a total of 189 patients. All patients had at least one actionable variant. The prevalence of patients having 2, 3, or 4 variants was 37.0%, 32.8%, and 12.7%, respectively. Potential alterations to medications were identified using the Clinical Decision Support System. Patients were accepting and the GPs were enthusiastic about the potential of pharmacogenetics to personalize medicine for their patients. CONCLUSION This is the first study in Singapore to demonstrate the feasibility of pharmacogenetic testing in primary care. The high prevalence of genetic variants underscores the potential use of pharmacogenetics in this setting.

INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2024; 59:1371-1385. [PMID: 38189112 DOI: 10.1111/1460-6984.13002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 12/11/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND Evidence supports the effectiveness of shared book reading for promoting language and literacy development, but it is known that families experiencing vulnerability may have reduced access to books and are less likely to share books regularly at home. Community hubs often provide support to families experiencing vulnerability and may provide an opportunity to create environments that support families to engage in shared book reading, especially if families are invited into the creation of these environments through co-design. However, there is currently little evidence regarding the impact of co-designing shared book reading environments with families in community settings. AIMS The current study is part of a broader project which used co-design to develop a shared book reading environment in collaboration with stakeholders in a community hub. This small-scale study aimed to provide a preliminary evaluation of the impact of this co-designed shared book reading environment at the community hub on (1) the frequency of shared book reading at the hub; (2) participants' confidence and enjoyment of reading with children at the hub; and (3) participants' experiences of shared book reading at the hub. METHOD & PROCEDURES The co-design project was carried out in four phases with families, staff and community partners at the community hub. A convergent mixed-methods approach was used to collect and analyse quantitative and qualitative data in the first and last phase of the project to evaluate project outcomes. Quantitative data (environmental observations of reading at the hub and participant ratings of confidence and enjoyment of reading with children at the hub) were analysed using descriptive statistics and nonparametric statistical tests. Qualitative data (participants' responses regarding their experiences of changes implemented in the community hub) were analysed using inductive content analysis. OUTCOME & RESULTS An increased frequency of shared book reading was observed within the community hub after changes were implemented, and positive changes in enjoyment of book reading were recorded. Qualitative responses from participants following conclusion of the project were organised into three main categories, which showed that (1) children and families were reading more and enjoying reading activities that were happening; (2) children and families were borrowing more books; and (3) families had changed the way they were reading at home with their children. CONCLUSIONS & IMPLICATIONS A co-designed shared book reading environment within a community hub had a positive impact on shared book reading experiences for families in areas with high levels of vulnerability. WHAT THIS PAPER ADDS What is already known on this subject Community hubs provide a unique opportunity to support early language and literacy development in partnership with families in areas of vulnerability; however, there is limited literature investigating the impacts of these supports. A previous study utilised co-design to develop a shared book reading environment with stakeholders at a community hub in an area where a high proportion of children are considered to be 'vulnerable' in terms of language and literacy development. It was found that co-design enabled the development of collaborative changes to support shared book reading that were valued and owned by families, staff and community partners at the community hub. What this study adds The current study focused on evaluating the impact of a co-design project on the frequency of shared book reading at the hub and participants' experiences, confidence and enjoyment of reading with children at the hub. Analysis of pre- and post-data provide preliminary evidence that a co-designed shared book reading environment in a community hub can have a positive impact on increasing families' awareness and engagement with book borrowing, engagement in shared book reading activities in the community and at home, and participants' confidence and enjoyment of reading with children. What are the clinical implications of this work? Speech pathologists have an important role to play in prevention and promotion. This study has shown that collaboration with families experiencing vulnerability can support the implementation of strategies to promote shared reading in a community hub and demonstrate increased quality and frequency of shared book reading. The utilisation of a community hub also highlights the opportunities for the speech pathology profession to deliver community-based promotion and prevention initiatives as a strategy to address equitable language outcomes.

Abstract
With the introduction of artificial intelligence (AI) to healthcare, there is also a need for professional guidance to support its use. New (2022) reports from National Health Service AI Lab & Health Education England focus on healthcare workers' understanding and confidence in AI clinical decision support systems (AI-CDDSs), and are concerned with developing trust in, and the trustworthiness of these systems. While they offer guidance to aid developers and purchasers of such systems, they offer little specific guidance for the clinical users who will be required to use them in patient care.This paper argues that clinical, professional and reputational safety will be risked if this deficit of professional guidance for clinical users of AI-CDDSs is not redressed. We argue it is not enough to develop training for clinical users without first establishing professional guidance regarding the rights and expectations of clinical users.We conclude with a call to action for clinical regulators: to unite to draft guidance for users of AI-CDDS that helps manage clinical, professional and reputational risks. We further suggest that this exercise offers an opportunity to address fundamental issues in the use of AI-CDDSs; regarding, for example, the fair burden of responsibility for outcomes.

Abstract
INTRODUCTION The Mental Welfare Commission for Scotland published a report into the death of a young person, with recommendations for the Royal College of Psychiatry in Scotland Child and Adolescent Faculty; to explore if there were barriers to the use of Clozapine in young people in Scotland. METHODS A mixed-methods study was performed using a cross-sectional survey of clinicians working in child and adolescent psychiatry across Scotland, to determine attitudes towards clozapine use and the perceived barriers and facilitators to clozapine treatment. RESULTS Results suggest that there may be a lack of clearly defined pathways within and between services, as well as a lack of resources provided for the necessary monitoring of a young person started on clozapine. Multiple respondents felt unskilled in clozapine initiation and had not accessed formal training. The most frequently mentioned themes for improving facilitation of clozapine prescription were that of increased resources and training. DISCUSSION National policymakers including the Mental Welfare Commission, NHS Education for Scotland, and NHS Scotland should consider these findings to address the potential underutilisation of clozapine for people aged under 18 in services across Scotland. A review of current service provision should take place, with consideration of whether the facilitators to clozapine prescription which our study has highlighted could be implemented more effectively. This may help reduce identified barriers and increase clozapine prescription to those who would benefit from it, potentially improving outcomes for young people with treatment-resistant psychosis.

Abstract
With a view to developing a much-needed non-invasive method for monitoring the healthy pluripotent state of human stem cells in culture, we undertook proteomic analysis of the waste medium from cultured embryonic (Man-13) and induced (Rebl.PAT) human pluripotent stem cells (hPSCs). Cells were grown in E8 medium to maintain pluripotency, and then transferred to FGF2 and TGFβ deficient E6 media for 48 hours to replicate an early, undirected dissolution of pluripotency. We identified a distinct proteomic footprint associated with early loss of pluripotency in both hPSC lines, and a strong correlation with changes in the transcriptome. We demonstrate that multiplexing of four E8- against four E6- enriched secretome biomarkers provides a robust, diagnostic metric for the pluripotent state. These biomarkers were further confirmed by Western blotting which demonstrated consistent correlation with the pluripotent state across cell lines, and in response to a recovery assay.

Abstract
BACKGROUND Speech and language skills are important for social interaction and learning. This study characterised the communication abilities of verbal individuals with SOX11 syndrome using a standardised parent/carer questionnaire, the Children's Communication Checklist (CCC-2). METHOD Thirteen parent/carers of verbal individuals (aged 5-19 years) diagnosed with SOX11 syndrome completed the CCC-2. In order to contextualise findings, responses were compared to norms and to data from Noonan syndrome, a relatively well-known genetic diagnosis associated with communication impairment. RESULTS For all individuals, the CCC-2 composite score indicated significant communication difficulties. Language structure (speech, syntax, semantics and coherence), pragmatic language (inappropriate initiation, stereotyped language use of context and non-verbal communication) and autistic features (social relations and interests) scores were lower than typically developing norms. Subscale comparisons revealed relative difference in use of context compared to other pragmatic domains (stereotyped language and inappropriate initiation). Individual scores showed substantial variation, particularly in regard to language structure profile. Differences were more pronounced than for Noonan syndrome, specifically in domains of speech, syntax, non-verbal communication and social relations. CONCLUSIONS SOX11 syndrome is associated with communication impairment. It is important to assess communication abilities as part of the management of individuals with SOX11 syndrome and understand individual strengths and difficulties in order to provide targeted support.

Abstract
INTRODUCTION International legal and political documents can assist policy-makers and programme managers in countries to create an enabling environment to promote maternal and newborn health. This review aimed to map and summarise international legal and political documents relevant to the implementation of the WHO recommendations on maternal and newborn care for a positive postnatal experience. METHODS Rapid review of relevant international legal and political documents, including legal and political commitments (declarations, resolutions and treaties) and interpretations (general comments, recommendations from United Nations human rights treaty bodies, joint United Nations statements). Documents were mapped to the domains presented in the WHO postnatal care (PNC) recommendations; relating to maternal care, newborn care, and health systems and health promotion interventions, and by type of human right implied and/or stated in the documents. RESULTS Twenty-nine documents describing international legal and political commitments and interpretations were mapped, out of 45 documents captured. These 29 documents, published or entered into force between 1944 and 2020, contained content relevant to most of the domains of the PNC recommendations, most prominently the domains of breastfeeding and health systems interventions and service delivery arrangements. The most frequently mapped human rights were the right to health and the right to social security. CONCLUSION Existing international legal and political documents can inform and encourage policy and programme development at the country level, to create an enabling environment during the postnatal period and thereby support the provision and uptake of PNC and improve health outcomes for women, newborns, children and families. Governments and civil society organisations should be aware of these documents to support efforts to protect and promote maternal and newborn health.

Abstract
Mn-doped UO2 is under consideration for use as an accident tolerant nuclear fuel. We detail the synthesis of Mn-doped UO2 prepared via a wet co-precipitation method, which was refined to improve the yield of incorporated Mn. To verify the Mn-doped UO2 defect chemistry, X-ray absorption spectroscopy at the Mn K-edge was performed, in addition to X-ray diffraction, Raman spectroscopy and high-energy resolved fluorescence detection X-ray absorption near edge spectroscopy at the U M4-edge. It was established that Mn2+ directly substitutes for U4+ in the UO2 lattice, accompanied by oxygen vacancy (Ov) charge compensation. In contrast to other divalent-element doped UO2 materials, compelling evidence for U5+ in a charge compensating role was not found. This work furthers understanding of the structure and crystal chemistry of Mn-doped UO2, which could show potential advantages as a novel efficient advanced nuclear fuel.

Abstract
In this study, we present an in-depth characterization of a diamond-like carbon (DLC) film, using a range of techniques to understand the structure and chemistry of the film both in the interior and particularly at the DLC/air surface and DLC/liquid interface. The DLC film is found to be a combination of sp2 and sp3 carbon, with significant oxygen present at the surface. The oxygen seems to be present as OH groups, making the DLC somewhat hydrophilic. Quartz-Crystal Microbalance (QCM) isotherms and complementary neutron reflectivity data indicate significant adsorption of a model additive, bis(2-ethylhexyl) sulfosuccinate sodium salt (AOT) surfactant, onto the DLC from water solutions and indicate the adsorbed film is a bilayer. This initial study of the structure and composition of a model surfactant is intended to give a clearer insight into how DLC and additives function as antiwear systems.

Abstract
Artificially intelligent systems (AISs) are being created by software developing companies (SDCs) to influence clinical decision-making. Historically, clinicians have led healthcare decision-making, and the introduction of AISs makes SDCs novel actors in the clinical decision-making space. Although these AISs are intended to influence a clinician's decision-making, SDCs have been clear that clinicians are in fact the final decision-makers in clinical care, and that AISs can only inform their decisions. As such, the default position is that clinicians should hold responsibility for the outcomes of the use of AISs. This is not the case when an AIS has influenced a clinician's judgement and their subsequent decision. In this paper, we argue that this is an imbalanced and unjust position, and that careful thought needs to go into how personal moral responsibility for the use of AISs in clinical decision-making should be attributed. This paper employs and examines the difference between prospective and retrospective responsibility and considers foreseeability as key in determining how personal moral responsibility can be justly attributed. This leads us to the view that moral responsibility for the outcomes of using AISs in healthcare ought to be shared by the clinical users and SDCs.

Abstract
PURPOSE/OBJECTIVE(S) Our prior work demonstrated that inhibition of MAPKAPK2 (MK2) can enhance radiation (RT)-mediated in vivo head and neck squamous cell carcinoma (HNSCC) tumor control and survival in preclinical immune incompetent models. The cytosolic DNA sensor cyclic GMP-AMP synthetase (cGAS) and its downstream adaptor protein, stimulator of interferon genes (STING), are conserved proteins within the innate immune signaling pathways and are important for mediating host defense against microbial infection and can play a role in anti-cancer immunity. We hypothesized that loss of MK2 enhances radiation-induced cGAS-STING pathway activation leading to improved tumor control and survival. MATERIALS/METHODS MK2 shRNA knockdown human (Tu167, CAL27) and MK2 Cas9/CRISPR knockout (KO) syngeneic murine (Ly2, MLM3) HNSCC cell lines were treated with 10 Gy irradiation. Micronuclei were quantitated by DAPI-immunofluorescence (IF). Protein changes in cGAS-STING were evaluated by immunoblot. Inflammatory cytokine production including Type I IFNβ1 were evaluated by RT-qPCR. Ly2 and MLM3 cells were orthotopically or flank engrafted into immune competent mice (Balb/c, C57Bl/6, respectively) for animal tumor control-survival studies. Tumor immune cell infiltrate was examined using FACS and immunohistochemistry. Selected drug studies using the MK2 inhibitor, ATI-450, were performed with RT. RESULTS Loss of MK2 in HNSCC (Tu167, CAL27, Ly2, MLM3) treated with RT led to a significant increase in micronuclei formation compared to control cells. MK2-enhanced micronuclei generation following RT could be inhibited with the actin filament polymerization inhibitor, cytochalasin B. RT treatment of MK2 shRNA cells led to increased cGAS and phospho-STING levels compared to either treatment alone. IFNβ1 levels were significantly higher in HNSCC cell lines treated with RT and with MK2 inhibited by an MK2 inhibitor (ATI-450) or genetic reduction compared to either treatment alone. In-vivo implantation of MLM3 cells into C57Bl/6 comparing control vs MK2 KO tumors treated with ±8 Gy RT demonstrated improved mouse survival favoring RT+MK2 KO over RT, MK2 KO or parental (63, 58, 58.5, 35 days, respectively). FACS analysis of MLM3 WT v KO tumors 3 days post RT showed an overall increase in the number of CD3/CD8 T-cells infiltrating into the tumor in all groups except for parental tumors. Further analysis demonstrated that loss of MK2 reversed CD8 T-cell exhaustion and when combined with radiotherapy led to increased CD8 T-cell activation. Furthermore, activated CD4 and CD8 T cells were reduced in WT+RT cells compared to WT tumors whereas no reduction was seen in the KO or KO+RT. CONCLUSION HNSCC tumor MK2 inhibition enhances RT-mediated micronuclei formation and subsequent cGAS-STING-IFNβ1 levels. Loss of HNSCC MK2 leads to increased CD4-CD8 T-cell infiltration into the tumor and this effect is enhanced following RT. Targeting tumor MK2 may facilitate improved tumor control.

Abstract
BACKGROUND Clinicians need easy access to evidence-based information to inform their clinical practice. Point-of-care information summaries are increasingly available in the form of smartphone apps. However, the quality of information from the apps is questionable as there is currently no regulation on the content of the medical apps. OBJECTIVES This study aimed to systematically assess the quality and content of the medical apps providing point-of-care information summaries that were available in two major app stores. We evaluated apps designed specifically for healthcare professionals and assessed their content development, editorial policy, coverage of medical conditions and trustworthiness. METHODS We conducted a systematic assessment of medical apps providing point-of-care information summaries available in Google Play and Apple app stores. Apps launched or updated since January 2020 were identified through a systematic search using 42matters. Apps meeting the inclusion criteria were downloaded and assessed. The data extraction and app assessment were done in parallel and independently by at least two reviewers. Apps were evaluated against the adapted criteria: (1) general characteristics, (2) content presentation of the summaries, (3) editorial quality, (4) evidence-based methodology, (5) coverage (volume) of the medical conditions, (6) usability of apps and (7) trustworthiness of the app based on HONcode principles. HONcode principles are guidelines used to inform users about the credibility and reliability of health information online. The results were reported as a narrative review. RESULTS Eight medical apps met the inclusion criteria and were systematically appraised. Based on our evaluation criteria, UpToDate supported 16 languages, and all other apps were English. Bullet points and brief paragraphs were used in all apps, and only DynaMed and Micromedex and Pathway-medical knowledge provided a formal grading system for the strength of recommendations for all the medical conditions in their apps. All the other apps either lacked a formal grading system altogether or offered one for some of the medical conditions. About 30% of the editorial quality assessment and 47.5% of the evidence-based methodology assessment were unclear or missing. UpToDate contained the most point-of-care evidence-based documents with >10 500 documents. All apps except 5-Minute Clinical Consult and DynaMed and Micromedex were available for offline access. Only Medscape complied with the HONcode principles. CONCLUSIONS Future apps should report a more detailed evidence-based methodology, be accessible for offline use and support search in more than one language. There should be clearer information provided in future apps regarding the declaration of authorship and conflict of interest.

Abstract
BACKGROUND Breslow thickness, patient age and ulceration are the three most valuable clinical and pathological predictors of melanoma survival. A readily available reliable online tool that accurately considers these and other predictors could be valuable for clinicians managing melanoma patients. OBJECTIVE To compare online melanoma survival prediction tools that request user input on clinical and pathological features. METHODS Search engines were used to identify available predictive nomograms. For each, clinical and pathological predictors were compared. RESULTS Three tools were identified. The American Joint Committee on Cancer tool inappropriately rated thin tumours as higher risk than intermediate tumours. The University of Louisville tool was found to have six shortcomings: a requirement for sentinel node biopsy, unavailable input of thin melanoma or patients over 70 years of age and less reliable hazard ratio calculations for age, ulceration and tumour thickness. The LifeMath.net tool was found to appropriately consider tumour thickness, ulceration, age, sex, site and tumour subtype in predicting survival. LIMITATIONS The authors did not have access to the base data used to compile various prediction tools. CONCLUSION The LifeMath.net prediction tool is the most reliable for clinicians in counselling patients with newly diagnosed primary cutaneous melanoma regarding their survival prospects.

Women's preconception health in England: a report card based on cross-sectional analysis of national maternity services data from 2018/2019. BJOG 2023; 130:1187-1195. [PMID: 36810878 PMCID: PMC10952348 DOI: 10.1111/1471-0528.17436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 11/17/2022] [Accepted: 11/29/2022] [Indexed: 02/24/2023]
Abstract
OBJECTIVE To present the first national-level report card on the state of women's preconception health in England. DESIGN Cross-sectional population-based study. SETTING Maternity services, England. POPULATION All pregnant women in England with a first antenatal (booking) appointment recorded in the national Maternity Services Dataset (MSDS) from April 2018 to March 2019 (n = 652 880). METHODS We analysed the prevalence of 32 preconception indicator measures in the overall population and across socio-demographic subgroups. Ten of these indicators were prioritised for ongoing surveillance based on modifiability, prevalence, data quality and ranking by multidisciplinary UK experts. RESULTS The three most prevalent indicators were the proportion of the 22.9% of women who smoked 1 year before pregnancy who did not quit smoking before pregnancy (85.0%), those who had not taken folic acid supplementation before pregnancy (72.7%) and previous pregnancy loss (38.9%). Inequalities were observed by age, ethnicity and area-based deprivation level. The ten indicators prioritised were not taking folic acid supplementation before pregnancy, obesity, complex social factors, living in the most deprived areas, smoking around the time of conception, overweight, pre-existing mental health condition, pre-existing physical health condition, previous pregnancy loss and previous obstetric complication. CONCLUSIONS Our findings suggest important opportunities to improve the state of preconception health and reduce socio-demographic inequalities for women in England. In addition to MSDS data, other national data sources that record further and possibly better quality indicators could be explored and linked to build a comprehensive surveillance infrastructure.

Abstract
OBJECTIVE To determine the effectiveness of an exercise and functional activity therapy intervention in adults with early dementia or mild cognitive impairment compared with usual care. DESIGN Randomised controlled trial. SETTING Participants' homes and communities at five sites in the United Kingdom. PARTICIPANTS 365 adults with early dementia or mild cognitive impairment who were living at home, and family members or carers. INTERVENTION The intervention, Promoting activity, Independence, and Stability in Early Dementia and mild cognitive impairment (PrAISED), was a specially designed, dementia specific, rehabilitation programme focusing on strength, balance, physical activity, and performance of activities of daily living, which was tailored and progressive and addressed risk and the psychological needs of people with dementia. Up to 50 therapy sessions were provided over 12 months. The control group received usual care plus a falls risk assessment. Procedures were adapted during the covid-19 pandemic. MAIN OUTCOME MEASURES The primary outcome was score on the carer (informant) reported disability assessment for dementia scale 12 months after randomisation. Secondary outcomes were self-reported activities of daily living, physical activity, quality of life, balance, functional mobility, fear of falling, frailty, cognition, mood, carer strain, service use at 12 months, and falls between months 4 and 15. RESULTS 365 patient participants were randomised, 183 to intervention and 182 to control. The median age of participants was 80 years (range 65-95), median Montreal cognitive assessment score was 20 out of 30 (range 13-26), and 58% (n=210) were men. Intervention participants received a median of 31 therapy sessions (interquartile range 22-40) and reported completing a mean 121 minutes of PrAISED exercise each week. Primary outcome data were available for 149 intervention and 141 control participants. Scores on the disability assessment for dementia scale did not differ between groups: adjusted mean difference -1.3, 95% confidence interval -5.2 to 2.6; Cohen's d effect size -0.06, 95% confidence interval -0.26 to 0.15; P=0.51). Upper 95% confidence intervals excluded small to moderate effects on any of the range of outcome measures. Between months 4 and 15 the intervention group experienced 79 falls and the control group 200 falls (adjusted incidence rate ratio 0.78, 95% confidence interval 0.5 to 1.3; P=0.3). CONCLUSION The intensive PrAISED programme of exercise and functional activity training did not improve activities of daily living, physical activity, or quality of life; reduce falls; or improve any other secondary health status outcomes, despite good uptake. Future research should consider alternative approaches to maintaining ability and wellbeing in people with dementia. TRIAL REGISTRATION ISRCTN Registry ISRCTN15320670.

Abstract
INTRODUCTION Discharge preparation prior to leaving a health facility after childbirth offers a critical window of opportunity for women, parents and newborns to receive support for the transition to care at home. However, research suggests that the quality of discharge preparation following childbirth is variable. This review synthesises qualitative evidence on stakeholder perspectives of postnatal discharge. METHODS We conducted a thematic synthesis of qualitative studies included in a larger published scoping review on discharge preparedness and readiness (reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews). For inclusion, in the qualitative evidence synthesis, studies had to have used qualitative methods for data collection and analysis to capture the perspectives of women, parents and health workers. Key characteristics and findings were extracted, and thematic analysis was used to inductively develop a conceptual coding framework. RESULTS Of a total of 130 research documents (published research articles and grey literature), six studies met the inclusion criteria; five were conducted in high-income countries, five were published in English and one was published in Swedish. Studies reported on the experiences of women, fathers and midwives with the number of participants ranging from 12 to 324. Nine descriptive themes (findings) were identified. From these, three high-level analytical themes were generated: (1) health workers need support to optimise the postnatal discharge process; (2) the allocated time for, and timing of, discharge is rushed; (3) overlooking women's and fathers'/partners' needs leads to feelings of exclusion. CONCLUSIONS Findings suggest an overall feeling of dissatisfaction among women, parents and midwives with the current provision of discharge preparation. In particular, women and midwives expressed frustration at the lack of time and resources available for ensuring adequate quality of care prior to discharge. The perspectives of included stakeholders indicate a demand for increased focus on the emotional and social needs of women and families during discharge preparation as well as better engagement of fathers and other family members. The qualitative evidence available indicates the likely positive impact of adequate discharge preparation if the identified service and system barriers can be overcome. As the updated WHO recommendations on postnatal care become embedded in country health systems and policies, there may be renewed interest on values, preferences and perspectives at system, service and end-user level.

Abstract
BACKGROUND Uncertainty around the risk of COVID-19 to pregnant women and their babies prompted precautionary restrictions on their health and care during the pandemic. Maternity services had to adapt to changing Government guidance. Coupled with the imposition of national lockdowns in England and restrictions on daily activities, women's experiences of pregnancy, childbirth and the postpartum period, and their access to services, changed rapidly. This study was designed to understand women's experiences of pregnancy, labour and childbirth and caring for a baby during this time. METHODS This was an inductive longitudinal qualitative study, using in-depth interviews by telephone with women in Bradford, UK, at three timepoints during their maternity journey (18 women at timepoint one, 13 at timepoint two and 14 at timepoint three). Key topics explored were physical and mental wellbeing, experience of healthcare services, relationships with partners and general impact of the pandemic. Data were analysed using the Framework approach. A longitudinal synthesis identified over-arching themes. RESULTS Three longitudinal themes captured what was important to women: (1) women feared being alone at critical points in their maternity journey, (2) the pandemic created new norms for maternity services and women's care, and (3) finding ways to navigate the COVID-19 pandemic in pregnancy and with a baby. CONCLUSIONS Modifications to maternity services impacted significantly on women's experiences. The findings have informed national and local decisions about how best to direct resources to reduce the impact of COVID-19 restrictions and the longer-term psychological impact on women during pregnancy and postnatally.

Abstract
PURPOSE Community hubs often provide support to families in areas of high vulnerability and can provide unique opportunities for delivering early literacy programs. This study used a co-design process to engage families, staff, and community partners within a community hub to design an environment that supported shared book reading. METHOD Co-design was enacted in four phases: 1) interviews to understand user experiences relating to shared book reading; 2) focus groups to refine ideas into actions to support shared book reading and prioritise these actions; 3) implementation of changes; and 4) understanding of participants' experiences of involvement. RESULT Participant identified changes were implemented within four categories: 1) changing how books are organised, 2) showing families how to share books, 3) giving families information about how books can be borrowed, and 4) running more activities about books. Participants indicated they enjoyed being a part of a co-design process to affect change at the community hub. CONCLUSION Co-design enabled the development of collaborative changes to support book reading that were valued and owned by families, staff, and community partners. Community hubs can provide unique opportunities to engage with families in areas of vulnerability to support the development of early language and literacy skills.
