A collaboratively produced model of service design for children and young people with common mental health problems.

BACKGROUND: Little is known about the effectiveness of, and implementation complexities associated with, service delivery models for children and young people (CYP) experiencing 'common' mental health problems such as anxiety, depression, behavioural difficulties and self-harm. This paper outlines how a model for high-quality service design for this population group was developed by identifying available services, their effectiveness, cost-effectiveness and acceptability, and the barriers and enablers to access. METHODS: Sequential, mixed-methods design, combining evidence syntheses (scoping and integrative reviews of the international literature) with primary research (a collective case study in England and Wales). Data from these two elements were collaboratively synthesised in a subsequent model-building phase. RESULTS: The scoping review yielded a service model typology. The integrative review found effectiveness evidence only for four models: collaborative care (the only service model to also have cost-effectiveness evidence), outreach approaches, brief intervention services and an organisational framework called 'Availability, Responsiveness and Continuity'. No service model seemed more acceptable than others. Three case study themes were identified: pathways to support; service engagement; and learning and understanding. The model-building phase identified rapid access, learning self-care skills, individualised support, clear information, compassionate and competent staff and aftercare planning as core characteristics of high-quality services. These characteristics were underpinned by four organisational qualities: values that respect confidentiality; engagement and involvement; collaborative relationships; and a learning culture. CONCLUSIONS: A consistent organisational evidence-base for service design and delivery in CYP's mental health spanning many years appears to have had little impact on service provision in England and Wales. Rather than impose - often inflexible and untested - specific local or national models or frameworks, those commissioning, designing and delivering mental health services for CYP should (re)focus on already known, fundamental components necessary for high-quality services. These fundamental components have been integrated into a collaboratively produced general model of service design for CYP with common mental health problems. While this general model is primarily focused on British service provision, it is broad enough to have utility for international audiences.

Maternal and Neonatal Effects of Maternal Oral Exposure to Perfluoro-2-methoxyacetic Acid (PFMOAA) during Pregnancy and Early Lactation in the Sprague-Dawley Rat.

Perfluoro-2-methoxyacetic acid (PFMOAA) is a short-chain perfluoroalkyl ether carboxylic acid that has been detected at high concentrations (∼10 µg/L) in drinking water in eastern North Carolina, USA, and in human serum and breastmilk in China. Despite documented human exposure there are almost no toxicity data available to inform risk assessment of PFMOAA. Here we exposed pregnant Sprague-Dawley rats to a range of PFMOAA doses (10-450 mg/kg/d) via oral gavage from gestation day (GD) 8 to postnatal day (PND) 2 and compared results to those we previously reported for perfluorooctanoic acid (PFOA) and hexafluoropropylene oxide-dimer acid (HFPO-DA or GenX). Newborn pups displayed reduced birthweight (≥30 mg/kg), depleted liver glycogen concentrations (all doses), hypoglycemia (≥125 mg/kg), and numerous significantly altered genes in the liver associated with fatty acid and glucose metabolism similar to gene changes produced by HFPO-DA. Pup survival was significantly reduced at ≥125 mg/kg, and at necropsy on PND2 both maternal and neonatal animals displayed increased liver weights, increased serum aspartate aminotransferase (AST), and reduced serum thyroid hormones at all doses (≥10 mg/kg). Pups also displayed highly elevated serum cholesterol at all doses. PFMOAA concentrations in serum and liver increased with maternal oral dose in both maternal and F1 animals and were similar to those we reported for PFOA but considerably higher than HFPO-DA. We calculated 10% effect levels (ED10 or EC10) and relative potency factors (RPF; PFOA = index chemical) among the three compounds based on maternal oral dose and maternal serum concentration (µM). Reduced pup liver glycogen, increased liver weights and reduced thyroid hormone levels (maternal and pup) were the most sensitive end points modeled. PFMOAA was ∼3-7-fold less potent than PFOA for most end points based on maternal serum RPFs, but slightly more potent for increased maternal and pup liver weights. PFMOAA is a maternal and developmental toxicant in the rat producing a constellation of adverse effects similar to PFOA and HFPO-DA.

Review: Crisis responses for children and young people - a systematic review of effectiveness, experiences and service organisation (CAMH-Crisis).

BACKGROUND: In England, one in six children aged 5-19 has a probable diagnosable mental health disorder. This is a major public health problem, with multiple agencies adopting varying approaches to care delivery for children and young people (CYP) in crisis. OBJECTIVES: To examine the organisation of crisis services across education, health, social care and voluntary sectors; the experiences and perceptions of CYP, families and staff; the effectiveness of current approaches to care and the goals of crisis intervention. METHODS: A systematic review of all relevant English language evidence regarding the provision and receipt of crisis support for CYP aged 5-25 (PROSPERO-CRD42019160134). Seventeen databases were searched from 1995 to 2021 and relevant UK-only grey literature was identified. Critical appraisal was conducted using appropriate design specific appraisal tools. A narrative approach to synthesis was conducted. RESULTS: In total, 138 reports (48 reports covering 42 primary research studies; 36 reports covering 39 descriptive accounts of the organisation services and 54 UK-only grey literature reports) were included. The evidence suggests that crisis services were organised as follows: triage/assessment-only, digitally mediated support approaches, and intervention approaches and models. When looking at experiences of crisis care, four themes were identified: (a) barriers and facilitators to seeking and accessing appropriate support; (b) what children and young people want from crisis services; (c) children's, young people's and families' experiences of crisis services; and (d) service provision. In determining effectiveness, the findings are summarised by type of service and were generated from single heterogenous studies. The goals of crisis services were identified. DISCUSSION: Despite a lack of high-quality international studies, findings suggest that support prior to reaching crisis point is important. From this work, various aspects of crisis care have been identified that can be incorporated into existing services across education, health, social care and the voluntary sector.

The INSIGHT project: reflections on the co-production of a quality recognition programme to showcase excellence in public involvement in health and care research.

BACKGROUND: The quality of Patient and Public Involvement (PPI) in healthcare research varies considerably and is frequently tokenistic. We aimed to co-produce the Insight | Public Involvement Quality Recognition and Awards programme, based on the UK Standards for Public Involvement (UKSPI) alongside an incremental scale designed by Expert Citizens (a lived experience-led community group), to incentivise and celebrate continuous improvement in PPI. METHODS: We used Task and Finish Groups (19/44 [43%] public contributor membership) to co-produce the programme which we piloted in three organisations with different healthcare research models. We used surveys and review sessions to capture learning and reflections. RESULTS: We co-created: (1) A Quality descriptor matrix comprising four incremental quality levels (Welcoming, Listening, Learning, Leading) for each UKSPI standard. (2) An assessment framework including guidance materials, self-assessment form and final report template. (3) An assessor training package. (4) The quality awards event format and nomination form. These materials were modified based on pilot-site feedback. Of survey respondents: 94.4% felt they had made at least 'Some' personal contribution (half said 'Quite a lot'/'A great deal'), 88.9% said they were 'Always'/'Often' able to express their views freely and, 100% stated the programme would have 'A lot of impact'/'Quite a bit of impact'. During the project, we identified the importance of taking time to explain project aims and contributor roles, adapting to the needs of individual contributors and, using smaller bespoke sessions outside the main Task and Finish Groups. CONCLUSIONS: We co-produced and piloted a quality recognition programme to incentivise and celebrate continuous quality improvement in PPI. One public contributor stated, "I feel strongly that the Insight framework and awards will raise awareness of the [public involvement] work going on in many community settings. [It] is likely to result in better sharing of positive practice, incentivising research groups of any size to start work or to improve the quality of [PPI] could be one of the main benefits. I'm excited that if this initiative takes off, regionally and then in the longer term nationally, it could be a significant step in advancing the [public] voice."

How researchers involve members of the public in health research varies widely. We developed a scheme that encourages researchers from any health research organisation to improve the quality of public involvement. We used joint workshops with researchers, health workers and members of the public to design the scheme. We then tested it in three research organisations. We recorded the experience of people taking part in the project to learn what went well and what could be improved. We looked at the six areas covered in the UK Standards for Public Involvement. For each area, we worked together to define four levels (Welcoming, Listening, Learning, Leading) of increasing quality. We designed the materials needed for organisations to take part in the scheme. We also created a training pack for assessors and the format of a celebration event. We modified the materials after testing them. We asked those who took part in the project, half of whom were lay members, what they thought. 94% felt they had made at least some personal contribution. 89% said they were often or always able to express their views freely. Everyone thought the project would have some degree of impact. Overall, those members of the public who took part said they enjoyed the process and felt that their views were listened to. Along the way, we learned that it was important to carefully explain the project's aims, be clear about roles and have 1to1 discussions outside the main workshops.

Crisis care for children and young people with mental health problems: national mapping, models of delivery, sustainability and experience (CAMH-Crisis2). A study protocol.

Background: One in six five 16-year-olds have a probable mental health difficulty. Of these, almost half of older teenagers and a quarter of 11-16-year-olds report having self-harmed or attempted suicide. Currently, there is little research into mental health crisis services for young people, with little understanding of what services exist, who uses them, or what works best. Question: 'How are mental health crisis responses for children and young people up to the age of 25 sustained, experienced and integrated within their local systems of services'? Objectives:     1.    To describe National Health Service (NHS), local authority, education and third sector approaches to the implementation and organisation of crisis care for children and young people across England and Wales.    2.   To identify eight contrasting case studies in which to evaluate how crisis services have developed and are currently organised, sustained, experienced and integrated within the context of their local systems of services.    3.   To compare and contrast these services in the context of the available international evidence, drawing out and disseminating clear implications for the design and delivery of future crisis responses for children and young people and their families. Methods: A sequential mixed methods approach, underpinned by normalisation process theory will be employed. A survey will create a detailed record of how crisis responses across England and Wales are organised, implemented and used. Subsequently, eight contrasting services in relation to geographic and socioeconomic setting, populations served, and service configuration will be identified as case studies. Interviews will be conducted with children, young people and parents/carers who have used the service, as well as commissioners, managers and practitioners. Operational policies and service usage data will also be examined. Analysis of how each service is provided, experienced, implemented and sustained will be conducted both inductively and deductively, reflecting normalisation process theory constructs.

BACKGROUND: There has been a sharp increase in children and young people experiencing extreme emotional distress and/or self-harm, which is also known as 'crisis'. Services for young people in crisis are a priority in the UK but little is currently known about what crisis services exist, who uses them, or what type of service works best. AIM AND OBJECTIVES: This project aims to explore the types of mental health crisis services currently available to children and young people up to the age of 25 in England and Wales, and to examine how they are organised, perceived and integrated within other local care systems. The objectives are to: 1. Find out what NHS, local authority, education and charity sector crisis services exist for children and young people across England and Wales, to describe the services and to create a database of them. 2. Identify eight contrasting services from the database and evaluate how these services are organised, perceived and integrated within local care systems. 3. Compare and contrast these services with the available international evidence, drawing out clear implications for the design and delivery of future crisis responses for children and young people and their families. METHODS: We will use a survey to create a database of crisis response services across England and Wales. From the database we will identify eight contrasting services and we will conduct interviews with children, young people and parents/carers who have used the service as well as managers and staff. We will look at how the services work and explore how they are used and by whom. We will compare and contrast each case study and consider findings of other research studies from around the world to draw clear, actionable, lessons for the future provision of high-quality crisis services for children and young people.

Dose additive maternal and offspring effects of oral maternal exposure to a mixture of three PFAS (HFPO-DA, NBP2, PFOS) during pregnancy in the Sprague-Dawley rat.

Simultaneous exposure to multiple per- and polyfluoroalkyl substances (PFAS) is common in humans across the globe. Individual PFAS are associated with adverse health effects, yet the nature of mixture effects after exposure to two or more PFAS remains unclear. Previously we reported that oral administration of hexafluoropropylene oxide-dimer acid (HFPO-DA, or GenX), Nafion byproduct 2 (NBP2), or perfluorooctane sulfonate (PFOS) individually during pregnancy produced maternal and F1 effects. Here, we hypothesized that responses to the combined exposure to these three PFAS would be dose additive. Pregnant Sprague-Dawley rats were exposed to a fixed-ratio equipotent mixture where the top dose contained each PFAS at their ED50 for neonatal mortality (100 % dose = PFOS 3 mg/kg; NBP2 10 mg/kg; HFPO-DA 110 mg/kg), followed by a dilution series (33.3, 10, 3.3, and 1 %) and vehicle controls (0 % dose). Consistent with the single chemical studies, dams were exposed from gestation day (GD)14-18 or from GD8-postnatal day (PND2). Fetal and maternal livers on GD18 displayed multiple significantly upregulated genes associated with lipid and carbohydrate metabolism at all dose levels, while dams displayed significantly increased liver weight (≥3.3 % dose) and reduced serum thyroid hormones (≥33.3 % dose). Maternal exposure from GD8-PND2 significantly reduced pup bodyweights at birth (≥33.3 % dose) and PND2 (all doses), increased neonatal liver weights (≥3.3 % dose), increased pup mortality (≥3.3 % dose), and reduced maternal bodyweights and weight gain at the top dose. Echocardiography of adult F1 males and females identified significantly increased left ventricular anterior wall thickness (~10 % increase), whereas other cardiac morphological, functional, and transcriptomic measures were unaffected. Mixture effects in maternal and neonatal animals conformed to dose addition using a relative potency factor (RPF) analysis. Results support dose addition-based cumulative assessment approaches for estimating combined effects of PFAS co-exposure.

A proposal to embed patient and public involvement within qualitative data collection and analysis phases of a primary care based implementation study.

BACKGROUND: Patient and public involvement (PPI) is increasingly seen as essential to health service research. There are strong moral and ethical arguments for good quality PPI. Despite the development of guidance aimed at addressing the inconsistent reporting of PPI activities within research, little progress has been made in documenting the steps taken to undertake PPI and how it influences the direction of a study. Without this information, there are minimal opportunities to share learnings across projects and strengthen future PPI practices. The aim of this paper is to present details on the processes and activities planned to integrate PPI into the qualitative research component of a mixed-methods, multi-site study evaluating the implementation of a smart template to promote personalised primary care for patients with multiple long-term conditions. METHODS: This proposal describes the processes and activities planned to integrate PPI into the development and piloting of qualitative data collection tools (topic guides for both practice staff and patients) and a tailored data analysis package developed for PPI members incorporating broad concepts and specific methods of qualitative data analysis. DISCUSSION: Outputs relating to PPI activity may include clear, concise and suitably worded topic guides for qualitative interviews. Piloting of the topic guides via mock interviews will further develop researchers' skills including sensitisation to the experiences of participants being interviewed. Working with PPI members when analysing the qualitative data aims to provide reciprocal learning opportunities and may contribute to improving the overall rigour of the data analysis. The intent of publishing proposed PPI activities within this project is to inform the future delivery of high quality PPI.

Patient and public involvement (PPI) improves healthcare research, however, there is little published evidence of proposed PPI activities within a research study. The aim of this article is to describe the proposed PPI activities which are to be integrated into a study implementing a smart template to promote personalised care for people with multiple long-term conditions within primary care in the United Kingdom. The proposal describes the ways in which PPI members will be included within the data collection and analysis phases of a research study which includes interviews with primary care staff and patients. PPI members will be asked to develop questions for these interviews and to take part in a mock interview whereby a researcher interviews a PPI member. The proposal also provides details on qualitative data analysis workshops which will be specifically developed for PPI members. The impact of PPI activities could include clear, concise and suitably worded questions used within the interviews. Piloting of these questions via mock interviews may enable researchers to further develop their interviewing skills. It is anticipated that involving PPI members when analysing qualitative data will provide opportunities for reciprocal learning and lead to rich interpretations of the data, inclusive of the PPI members' perspectives. Publishing a record of planned PPI activities and potential impacts demonstrates the rationale and considerations made by the team to ensure that involvement in this study is meaningful and has potential benefits for all involved. The team hopes this proposal will support others with the planning and delivery of PPI activities. In future publications, we will reflect on the learnings, challenges, and outcomes from the PPI activities detailed in this proposal.

Structural Analysis of Bacillus subtilis Sigma Factors.

Bacteria use an array of sigma factors to regulate gene expression during different stages of their life cycles. Full-length, atomic-level structures of sigma factors have been challenging to obtain experimentally as a result of their many regions of intrinsic disorder. AlphaFold has now supplied plausible full-length models for most sigma factors. Here we discuss the current understanding of the structures and functions of sigma factors in the model organism, Bacillus subtilis, and present an X-ray crystal structure of a region of B. subtilis SigE, a sigma factor that plays a critical role in the developmental process of spore formation.

Perceptions of the key components of effective, acceptable and accessible services for children and young people experiencing common mental health problems: a qualitative study.

BACKGROUND: Children and young people's (CYP) mental health is a major public health concern internationally and the recent Covid-19 pandemic has amplified these concerns. However, only a minority of CYP receive support from mental health services due to the attitudinal and structural barriers they and their families encounter. For over 20 years, report after report has consistently highlighted the shortcomings of mental health services for CYP in the United Kingdom and attempts to improve services have been largely unsuccessful. The findings reported in this paper are from a multi-stage study that aimed to develop a model of effective, high-quality service design for CYP experiencing common mental health problems. The aim of the stage reported here was to identify CYP's, parents' and service providers' perceptions of the effectiveness, acceptability and accessibility of services. METHODS: Case studies were conducted of nine different services for CYP with common mental health problems in England and Wales. Data were collected using semi-structured interviews with 41 young people, 26 parents and 41 practitioners and were analysed using the Framework approach. Patient and Public Involvement was integrated throughout the study with a group of young co-researchers participating in data collection and analysis. RESULTS: Four key themes defined participants' perceptions of service effectiveness, acceptability and accessibility. Firstly, open access to support with participants highlighting the importance of self-referral, support at the point of need and service availability to CYP/parents. Secondly, the development of therapeutic relationships to promote service engagement which was based on assessment of practitioner's personal qualities, interpersonal skills and mental health expertise and underpinned by relational continuity. Thirdly, personalisation was viewed as promoting service appropriateness and effectiveness by ensuring support was tailored to the individual. Fourthly, the development of self-care skills and mental health literacy helped CYP/parents manage and improve their/their child's mental health problems. CONCLUSIONS: This study contributes to knowledge by identifying four components that are perceived to be central to providing effective, acceptable and accessible mental health services for CYP with common mental health problems irrespective of service model or provider. These components could be used as the foundations for designing and improving services.

Juxtaposition of intensive agriculture, vulnerable aquifers, and mixed chemical/microbial exposures in private-well tapwater in northeast Iowa.

In the United States and globally, contaminant exposure in unregulated private-well point-of-use tapwater (TW) is a recognized public-health data gap and an obstacle to both risk-management and homeowner decision making. To help address the lack of data on broad contaminant exposures in private-well TW from hydrologically-vulnerable (alluvial, karst) aquifers in agriculturally-intensive landscapes, samples were collected in 2018-2019 from 47 northeast Iowa farms and analyzed for 35 inorganics, 437 unique organics, 5 in vitro bioassays, and 11 microbial assays. Twenty-six inorganics and 51 organics, dominated by pesticides and related transformation products (35 herbicide-, 5 insecticide-, and 2 fungicide-related), were observed in TW. Heterotrophic bacteria detections were near ubiquitous (94 % of the samples), with detection of total coliform bacteria in 28 % of the samples and growth on at least one putative-pathogen selective media across all TW samples. Health-based hazard index screening levels were exceeded frequently in private-well TW and attributed primarily to inorganics (nitrate, uranium). Results support incorporation of residential treatment systems to protect against contaminant exposure and the need for increased monitoring of rural private-well homes. Continued assessment of unmonitored and unregulated private-supply TW is needed to model contaminant exposures and human-health risks.

Bottled water contaminant exposures and potential human effects.

BACKGROUND: Bottled water (BW) consumption in the United States and globally has increased amidst heightened concern about environmental contaminant exposures and health risks in drinking water supplies, despite a paucity of directly comparable, environmentally-relevant contaminant exposure data for BW. This study provides insight into exposures and cumulative risks to human health from inorganic/organic/microbial contaminants in BW. METHODS: BW from 30 total domestic US (23) and imported (7) sources, including purified tapwater (7) and spring water (23), were analyzed for 3 field parameters, 53 inorganics, 465 organics, 14 microbial metrics, and in vitro estrogen receptor (ER) bioactivity. Health-benchmark-weighted cumulative hazard indices and ratios of organic-contaminant in vitro exposure-activity cutoffs were assessed for detected regulated and unregulated inorganic and organic contaminants. RESULTS: 48 inorganics and 45 organics were detected in sampled BW. No enforceable chemical quality standards were exceeded, but several inorganic and organic contaminants with maximum contaminant level goal(s) (MCLG) of zero (no known safe level of exposure to vulnerable sub-populations) were detected. Among these, arsenic, lead, and uranium were detected in 67 %, 17 %, and 57 % of BW, respectively, almost exclusively in spring-sourced samples not treated by advanced filtration. Organic MCLG exceedances included frequent detections of disinfection byproducts (DBP) in tapwater-sourced BW and sporadic detections of DBP and volatile organic chemicals in BW sourced from tapwater and springs. Precautionary health-based screening levels were exceeded frequently and attributed primarily to DBP in tapwater-sourced BW and co-occurring inorganic and organic contaminants in spring-sourced BW. CONCLUSION: The results indicate that simultaneous exposures to multiple drinking-water contaminants of potential human-health concern are common in BW. Improved understandings of human exposures based on more environmentally realistic and directly comparable point-of-use exposure characterizations, like this BW study, are essential to public health because drinking water is a biological necessity and, consequently, a high-vulnerability vector for human contaminant exposures.

Cumulative maternal and neonatal effects of combined exposure to a mixture of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) during pregnancy in the Sprague-Dawley rat.

Globally, biomonitoring data demonstrate virtually all humans carry residues of multiple per- and polyfluoroalkyl substances (PFAS). Despite pervasive co-exposure, limited mixtures-based in vivo PFAS toxicity research has been conducted. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are commonly detected PFAS in human and environmental samples and both produce adverse effects in laboratory animal studies, including maternal and offspring effects when orally administered during pregnancy and lactation. To evaluate the effects of combined exposure to PFOA and PFOS, we orally exposed pregnant Sprague-Dawley rats from gestation day 8 (GD8) to postnatal day 2 (PND2) to PFOA (10-250 mg/kg/d) or PFOS (0.1-5 mg/kg/d) individually to characterize effects and dose response curve parameters, followed by a variable-ratio mixture experiment with a constant dose of PFOS (2 mg/kg/d) mixed with increasing doses of PFOA (3-80 mg/kg/d). The mixture study design was intended to: 1) shift the PFOA dose response curves for endpoints shared with PFOS, 2) allow comparison of dose addition (DA) and response addition (RA) model predictions, 3) conduct relative potency factor (RPF) analysis for multiple endpoints, and 4) avoid overt maternal toxicity. Maternal serum and liver concentrations of PFOA and PFOS were consistent between the individual chemical and mixture experiments. Combined exposure with PFOS significantly shifted the PFOA dose response curves towards effects at lower doses compared to PFOA-only exposure for multiple endpoints and these effects were well predicted by dose addition. For endpoints amenable to mixture model analyses, DA produced equivalent or better estimates of observed data than RA. All endpoints evaluated were accurately predicted by RPF and DA approaches except for maternal gestational weight gain, which produced less-than-additive results in the mixture. Data support the hypothesis of cumulative effects on shared endpoints from PFOA and PFOS co-exposure and dose additive approaches for predictive estimates of mixture effects.

Tapwater Exposures, Effects Potential, and Residential Risk Management in Northern Plains Nations.

In the United States (US), private-supply tapwater (TW) is rarely monitored. This data gap undermines individual/community risk-management decision-making, leading to an increased probability of unrecognized contaminant exposures in rural and remote locations that rely on private wells. We assessed point-of-use (POU) TW in three northern plains Tribal Nations, where ongoing TW arsenic (As) interventions include expansion of small community water systems and POU adsorptive-media treatment for Strong Heart Water Study participants. Samples from 34 private-well and 22 public-supply sites were analyzed for 476 organics, 34 inorganics, and 3 in vitro bioactivities. 63 organics and 30 inorganics were detected. Arsenic, uranium (U), and lead (Pb) were detected in 54%, 43%, and 20% of samples, respectively. Concentrations equivalent to public-supply maximum contaminant level(s) (MCL) were exceeded only in untreated private-well samples (As 47%, U 3%). Precautionary health-based screening levels were exceeded frequently, due to inorganics in private supplies and chlorine-based disinfection byproducts in public supplies. The results indicate that simultaneous exposures to co-occurring TW contaminants are common, warranting consideration of expanded source, point-of-entry, or POU treatment(s). This study illustrates the importance of increased monitoring of private-well TW, employing a broad, environmentally informative analytical scope, to reduce the risks of unrecognized contaminant exposures.

Prevalence of frailty and cognitive impairment in older transplant candidates - a preview to the Kidney Transplantation in Older People (KTOP): impact of frailty on outcomes study.

BACKGROUND: Kidney transplantation in older people has increased, however older transplant recipients experience mixed outcomes that invariably impacts on their quality of life. The increased vulnerability of older end stage kidney disease patients to frailty and cognitive impairment, may partially explain the differences in outcomes observed. The Kidney Transplantation in Older People (KTOP): impact of frailty on clinical outcomes study is an active clinical study aiming to explore the experience of older people waiting for and undergoing transplantation. In this manuscript we present the study protocol, the study cohort, and the prevalence of frailty and cognitive impairment identified at recruitment. METHODS: The KTOP study is a single centre, prospective, mixed methods, observational study. Recruitment began in October 2019. All patients aged 60 or above either active on the deceased donor waitlist or undergoing live donor transplantation were eligible for recruitment. Recruited participants completed a series of questionnaires assessing frailty, cognition, and quality of life, which are repeated at defined time points whilst on the waitlist and post-transplant. Clinical data was concurrently collected. Any participants identified as frail or vulnerable were also eligible for enrolment into the qualitative sub-study. RESULTS: Two hundred eight participants have been recruited (age 60-78). Baseline Montreal Cognitive Assessments were available for 173 participants, with 63 (36.4%) participants identified as having scores below normal (score < 26). Edmonton Frail Scale assessments were available for 184 participants, with 29 participants (15.8%) identified as frail (score ≥ 8), and a further 37 participants (20.1%) identified as being vulnerable (score 6-7). CONCLUSION: In the KTOP study cohort we have identified a prevalence of 36.4% of participants with MoCA scores suggestive of cognitive impairment, and a prevalence of frailty of 15.8% at recruitment. A further 20.1% were vulnerable. As formal testing for cognition and frailty is not routinely incorporated into the work up of older people across many units, the presence and significance of these conditions is likely not known. Ultimately the KTOP study will report on how these parameters evolve over time and following a transplant, and describe their impact on quality of life and clinical outcomes.

The experiences and needs of supporting individuals of young people who self-harm: A systematic review and thematic synthesis.

Self-harm in young people is a serious international health concern that impacts on those providing informal support: the supporting individuals of young people. We aimed to highlight the experiences, views, and needs of these supporting individuals of young people. We conducted a systematic review and thematic synthesis: PROSPERO CRD42020168527. MEDLINE, PsycINFO, EMBASE, AMED, CINAHL, ASSIA, and Web of Science were searched from inception to 6 May 2020 with citation tracking of eligible studies done on 1 Oct 2021. Primary outcomes were experiences, perspectives, and needs of parents, carers, or other family members of young people aged 12-25. Searches found 6167 citations, of which 22 papers were included in synthesis. Supporting individuals seek an explanation for and were personally affected by self-harm in young people. It is important that these individuals are themselves supported, especially as they negotiate new identities when handling self-harm in young people, as they attempt to offer support. The GRADE-CERQual confidence in findings is moderate. Recommendations informed by the synthesis findings are made for the future development of interventions. Clinicians and health service providers who manage self-harm in young people should incorporate these identified unmet needs of supporting individuals in a holistic approach to self-harm care. Future research must co-produce and evaluate interventions for supporting individuals. Funding: FM was supported by a NIHR School for Primary Care Research GP Career Progression Fellowship (SCPR-157 2020-20) to undertake this review and is now funded by a NIHR Doctoral Fellowship (NIHR300957). CCG is part-funded by the NIHR Applied Research Collaboration West Midlands.

In vitro activity of a panel of per- and polyfluoroalkyl substances (PFAS), fatty acids, and pharmaceuticals in peroxisome proliferator-activated receptor (PPAR) alpha, PPAR gamma, and estrogen receptor assays.

Data demonstrate numerous per- and polyfluoroalkyl substances (PFAS) activate peroxisome proliferator-activated receptor alpha (PPARα), however, additional work is needed to characterize PFAS activity on PPAR gamma (PPARγ) and other nuclear receptors. We utilized in vitro assays with either human or rat PPARα or PPARγ ligand binding domains to evaluate 16 PFAS (HFPO-DA, HFPO-DA-AS, NBP2, PFMOAA, PFHxA, PFOA, PFNA, PFDA, PFOS, PFBS, PFHxS, PFOSA, EtPFOSA, and 4:2, 6:2 and 8:2 FTOH), 3 endogenous fatty acids (oleic, linoleic, and octanoic), and 3 pharmaceuticals (WY14643, clofibrate, and the metabolite clofibric acid). We also tested chemicals for human estrogen receptor (hER) transcriptional activation. Nearly all compounds activated both PPARα and PPARγ in both human and rat ligand binding domain assays, except for the FTOH compounds and PFOSA. Receptor activation and relative potencies were evaluated based on effect concentration 20% (EC20), top percent of max fold induction (pmaxtop), and area under the curve (AUC). HFPO-DA and HFPO-DA-AS were the most potent (lowest EC20, highest pmaxtop and AUC) of all PFAS in rat and human PPARα assays, being slightly less potent than oleic and linoleic acid, while NBP2 was the most potent in rat and human PPARγ assays. Only PFHxS, 8:2 and 6:2 FTOH exhibited hER agonism >20% pmax. In vitro measures of human and rat PPARα and PPARγ activity did not correlate with oral doses or serum concentrations of PFAS that induced increases in male rat liver weight from the National Toxicology Program 28-d toxicity studies. Data indicate that both PPARα and PPARγ activation may be molecular initiating events that contribute to the in vivo effects observed for many PFAS.

Trends in emergency department litigation within the NHS: a retrospective database analysis.

The objectives of this study are to examine trends in litigation related to emergency department care within the NHS. The study is based on retrospective database analysis. NHS Resolution databases of litigation activity pertaining to Type I emergency departments within the NHS are used. The main outcome measures were number of claims, number of successful claims, costs associated with litigation and costs per claim, all in comparison to patterns of ED attendance numbers and inflation. The results showed that the annual cost of litigation relating to emergency department care within the NHS has increased from £25.5 million in 2005/6 to £161.9 million in 2017/18. Mean cost per claim has increased from £58,252 in 2005/6 to £168,966 in 2017/18. The number of claims received has increased significantly; the proportion of these which were successful has remained constant. Therefore, it was concluded that the costs of litigation are increasing disproportionately to inflation and attendance numbers. Multiple potential causes are discussed, with significant implications for clinical practice.

First Contact Practitioners' (FCPs) and General Practitioners' Perceptions Towards FCPs Delivering Vocational Advice to Patients with Musculoskeletal Conditions: A Qualitative Investigation of the Implementation Potential of the I-SWAP Initiative.

Purpose Musculoskeletal (MSK) pain is a common cause of work absence. The recent SWAP (Study of Work And Pain) randomised controlled trial (RCT) found that a brief vocational advice service for primary care patients with MSK pain led to fewer days' work absence and provided good return-on-investment. The I-SWAP (Implementation of the Study of Work And Pain) initiative aimed to deliver an implementation test-bed of the SWAP vocational advice intervention with First Contact Practitioners (FCP). This entailed adapting the SWAP vocational advice training to fit the FCP role. This qualitative investigation explored the implementation potential of FCPs delivering vocational advice for patients with MSK pain. Methods Semi-structured interviews and focus groups were conducted with 10 FCPs and 5 GPs. Data were analysed thematically and findings explored using Normalisation Process Theory (NPT). Results I-SWAP achieved a degree of 'coherence' (i.e. made sense), with both FCPs and GPs feeling FCPs were well-placed to discuss work issues with these patients. However, for many of the FCPs, addressing or modifying psychosocial and occupational barriers to return-to-work was not considered feasible within FCP consultations, and improving physical function was prioritised. Concerns were also raised that employers would not act on FCPs' recommendations regarding return-to-work. Conclusion FCPs appear well-placed to discuss work issues with MSK patients, and signpost/refer to other services; however, because they often only see patients once they are less suited to deliver other aspects of vocational advice. Future research is needed to explore how best to provide vocational advice in primary care settings.

Developing Pretend Play in Autistic Children Using the Playboxes Joint Play Approach as Part of Ongoing Practice.

A repeated measures single subject design was used to examine the effectiveness of a joint play approach embedded in professional practice, in supporting pretend play for autistic children. Seven autistic children, aged 5-8 years, with a placement within a specialist educational provision, and who demonstrated restricted play, participated in weekly sessions using the Playboxes approach over a period of 3 months. Pre- and post-approach pretend play abilities were assessed using the Symbolic Play Test and the Test of Pretend Play. Every child gained increased age-equivalent scores on the Test of Pretend Play, ranging from + 8 to + 30 months. Pretend Play abilities can support developmental outcomes and incorporation of this approach into regular practice could be of value for autistic children.

Developmental toxicity of Nafion byproduct 2 (NBP2) in the Sprague-Dawley rat with comparisons to hexafluoropropylene oxide-dimer acid (HFPO-DA or GenX) and perfluorooctane sulfonate (PFOS).

Nafion byproduct 2 (NBP2) is a polyfluoroalkyl ether sulfonic acid that was recently detected in surface water, drinking water, and human serum samples from monitoring studies in North Carolina, USA. We orally exposed pregnant Sprague-Dawley rats to NBP2 from gestation day (GD) 14-18 (0.1-30 mg/kg/d), GD17-21, and GD8 to postnatal day (PND) 2 (0.3-30 mg/kg/d) to characterize maternal, fetal, and postnatal effects. GD14-18 exposures were also conducted with perfluorooctane sulfonate (PFOS) for comparison to NBP2, as well as data previously published for hexafluoropropylene oxide-dimer acid (HFPO-DA or GenX). NBP2 produced stillbirth (30 mg/kg), reduced pup survival shortly after birth (10 mg/kg), and reduced pup body weight (10 mg/kg). Histopathological evaluation identified reduced glycogen stores in newborn pup livers and hepatocyte hypertrophy in maternal livers at ≥ 10 mg/kg. Exposure to NBP2 from GD14-18 reduced maternal serum total T3 and cholesterol concentrations (30 mg/kg). Maternal, fetal, and neonatal liver gene expression was investigated using RT-qPCR pathway arrays, while maternal and fetal livers were also analyzed using TempO-Seq transcriptomic profiling. Overall, there was limited alteration of genes in maternal or F1 livers from NBP2 exposure with significant changes mostly occurring in the top dose group (30 mg/kg) associated with lipid and carbohydrate metabolism. Metabolomic profiling indicated elevated maternal bile acids for NBP2, but not HFPO-DA or PFOS, while all three reduced 3-indolepropionic acid. Maternal and fetal serum and liver NBP2 concentrations were similar to PFOS, but ∼10-30-fold greater than HFPO-DA concentrations at a given maternal oral dose. NBP2 is a developmental toxicant in the rat, producing neonatal mortality, reduced pup body weight, reduced pup liver glycogen, reduced maternal thyroid hormones, and altered maternal and offspring lipid and carbohydrate metabolism similar to other studied PFAS, with oral toxicity for pup loss that is slightly less potent than PFOS but more potent than HFPO-DA.
