'On paper, you're normal': narratives of unseen health needs among women who have had children removed from their care.

BACKGROUND: Mothers who have children removed from their care often have complex needs. These women have poor health outcomes and are dying earlier than their peers from preventable and amenable causes. Yet there is little known about how health care services might mitigate these risks. This study aimed to listen to the voices of women who had children removed from their care to understand their experiences of health and healthcare. METHODS: We used a narrative approach to collect and analyse interview data with six mothers who had experienced child removal in England. Each participant was asked to reflect on their life and main health challenges. RESULTS: Three narrative subplots were developed to consolidate experiences of unmet health need: (i) 'on paper you're normal': narratives of complex need, (ii) 'in my family, everyone had issues': narratives of whole family need and (iii) 'I'm still mummy, no matter where they are': narratives of maternal identity and health. CONCLUSIONS: Findings highlight limitations within current systems of support, including a culture of distrust and women falling between the gaps of services. Women's narratives illustrate opportunities for health intervention, especially immediately following child removal.

Impact of counselling provision in primary schools on child and adolescent mental health service referral rates: a longitudinal observational cohort study.

BACKGROUND: In the United Kingdom, schools play an increasingly important role in supporting young peoples' mental health. While there is a growing evidence base to support the effectiveness of school-based interventions, less is known about how these provisions impact on local Child and Adolescent Mental Health Service (CAMHS) referral rates. There is a concern that an increase in school-based provision might lead to an increase in CAMHS referrals and overwhelm services. We aimed to examine the longitudinal association between Place2Be counselling provision in primary schools on CAMHS referral rates in South London. METHOD: This was a retrospective cohort study using linked data from the National Pupil Database (NPD) and CAMHS referrals to the South London and Maudsley's NHS Foundation Trust (SLaM) identified through the Clinical Record Interactive Search (CRIS) tool. The cohort included a total of 285 state-maintained primary schools in four London boroughs for the academic years of 2007-2012. During the study period, 23 of these schools received school-based mental health provision from Place2Be. The primary outcome was the incident rate ratio (IRR) of school-level accepted CAMHS referrals in 2012/13 in schools with, or without, Place2Be provision. RESULTS: There was no significant association between elevated rates of CAMHS referral and Place2Be provision, even after comprehensive adjustment for school-level and pupil characteristics (IRR 0.91 (0.67-1.23)). School-level characteristics, including higher proportion of white-British pupils (IRR 1.009 (1.002-1.02)), medical staff ratio (IRR 6.49 (2.05-20.6)) and poorer Ofsted school inspection ratings (e.g. IRR 1.58 (1.06-2.34) for 'Requires Improvement' vs. 'Outstanding') were associated with increased CAMHS referral rates. CONCLUSIONS: Place2Be provision did not result in increased specialist mental health referrals; however, other school-level characteristics did. Future research should investigate pupils' Place2Be clinical outcomes, as well the outcomes of individuals referred to CAMHS to better understand which needs are being met by which services.

ABCB4 Mutations in Adults Cause a Spectrum Cholestatic Disorder Histologically Distinct from Other Biliary Disease.

BACKGROUND: Mutations in the ABCB4 gene are associated with failure of bile acid emulsification leading to cholestatic liver disease. Presentations range from progressive familial intrahepatic cholestasis type 3 (PFIC3) in childhood, to milder forms seen in adulthood. AIMS: We sought to characterize adult disease with particular reference to histology which has been hitherto poorly defined. METHODS: Four unrelated adults (three female, mean age 39 years) and three sisters presenting with cholestatic liver disease in adulthood, associated with variants in the ABCB4 gene, were identified. Clinical review and detailed blinded histopathological analysis were performed. RESULTS: Two novel pathogenic ABCB4 variants were identified: c.620 T > G, p.(Ile207Arg) and c.2301dupT, p.(Thr768TyrfsTer26). Sub-phenotypes observed included low-phospholipid-associated cholelithiasis syndrome (LPAC), intrahepatic cholestasis of pregnancy (ICP), drug-induced cholestasis, idiopathic adulthood ductopenia, and adult PFIC3. Of note, 5/7 had presented with gallstone complications (4 meeting LPAC definition) and 4/6 females had a history of ICP. Considerable overlap was observed phenotypically and liver transplantation was required in 3/7 of patients. Histologically, cases generally demonstrated ductopenia of the smaller tracts, mild non-ductocentric portal inflammation, bilirubinostasis, significant copper-associated protein deposition, and varying degrees of fibrosis. CONCLUSIONS: Adults with ABCB4 mutations may harbor a spectrum of cholestatic disease phenotypes and can progress to liver transplantation. We observed a distinct histological pattern which differs from classical biliary disease and describe two novel pathogenic ABCB4 variants. ABCB4 sequencing should be considered in patients with relevant cholestatic phenotypes and/or suggestive histology; accurate diagnosis can guide potential interventions to delay progression and inform family screening.

Mental health service use among mothers involved in public family law proceedings: linked data cohort study in South London 2007-2019.

PURPOSE: Mental health problems and substance misuse are common among the mothers of children who experience court-mandated placement into care in England, yet there is limited research characterising these health needs to inform evidence-based policy. In this descriptive study, we aimed to generate evidence about the type, severity, and timing of mental health and substance misuse needs among women involved in public family law proceedings concerning child placement into care ('care proceedings'). METHODS: This is a retrospective, matched cohort study using linked family court and mental health service records for 2137 (66%) of the 3226 women involved in care proceedings between 2007 and 2019 in the South London and Maudsley NHS Mental Health Trust (SLaM) catchment area. We compared mental health service use and risk of dying with 17,096 female-matched controls who accessed SLaM between 2007 and 2019, aged 16-55 years, and were not involved in care proceedings. RESULTS: Most women (79%) were known to SLaM before care proceedings began. Women had higher rates of schizophrenia spectrum disorders (19% vs 11% matched controls), personality disorders (21% vs 11%), and substance misuse (33% vs 12%). They were more likely to have a SLaM inpatient admission (27% vs 14%) or to be sectioned (19% vs 8%). Women had a 2.15 (95% CI 1.68-2.74) times greater hazard of dying, compared to matched controls, adjusted for age. CONCLUSION: Women involved in care proceedings experience a particularly high burden of severe and complex mental health and substance misuse need. Women's increased risk of mortality following proceedings highlights that interventions responding to maternal mental health and substance misuse within family courts should offer continued, long-term support.

What are the perspectives of speech pathologists, occupational therapists and physiotherapists on using telehealth videoconferencing for service delivery to children with developmental delays? A systematic review of the literature.

OBJECTIVE: To identify the attitudes and perspectives of speech pathologists, occupational therapists and physiotherapists on using telehealth videoconferencing for service delivery to children with developmental delays. DESIGN: Systematic Literature Review. METHOD: An electronic search of databases Scopus, CINAHL, MEDLINE, PEDro, Speechbite, OTseeker and ScienceDirect was undertaken in October 2020. Articles were compared with eligibility criteria by 2 authors. All articles were appraised for quality and level of evidence. FINDINGS: Fourteen studies were deemed to be eligible. Results were synthesised using a narrative analysis. The themes identified were technology, self-efficacy, replacement of face-to-face services, time management, relationships, access and family-centred care. Each of these themes was seen as both a potential barrier and a facilitator when trying to provide services via telehealth. CONCLUSIONS: The results in this review cannot be generalised due to small sampling size, low response rates, lack of maximum variation sampling and under-representation of occupational therapists and physiotherapists. Study design was either mixed-methods survey or interview or only survey or interview. Risk of bias in studies was high. Further research is required including comparison studies and cost-benefit analysis.

Parenting interventions for people with schizophrenia or related serious mental illness.

BACKGROUND: Around a third of people with schizophrenia or related serious mental illness will be a parent. Both the parents and the children in this population are at increased risk of adverse outcomes due to parental mental illness. Parenting interventions are known to improve parenting skills and decrease child disruptive behaviour. This systematic review aimed to synthesise the evidence base for parenting interventions designed specifically for parents who have schizophrenia or related serious mental illness. OBJECTIVES: To assess the effects of parenting interventions for people with schizophrenia or related serious mental illness. SEARCH METHODS: On 10 February 2021 we searched the Cochrane Schizophrenia Group's Study-Based Register of Trials, which is based on the following: Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), ClinicalTrials.Gov, Embase, International Standard Randomised Controlled Trial Number (ISRCTN), MEDLINE, PsycINFO, PubMed, and the World Health Organization International Clinical Trials Registry Platform. SELECTION CRITERIA: Eligible studies were randomised controlled trials (RCTs) that compared parenting interventions with a control condition for people with schizophrenia or related serious mental illness with a child between the ages of 0 and 18 years. DATA COLLECTION AND ANALYSIS: We independently inspected citations, selected studies, extracted data and appraised study quality. We assessed risk of bias for included studies. MAIN RESULTS: We only included one trial (n = 50), and it was not possible to extract any data because the authors did not provide any means and standard deviations for our outcomes of interest; they only reported whether outcomes were significant or not at the 0.05 level. Three domains of the trial were rated as having a high risk of bias. AUTHORS' CONCLUSIONS: The only included trial provided inconclusive evidence. There is insufficient evidence to make recommendations to people with schizophrenia (or related serious mental illness) or clinicians, or for policy changes. Although there is no RCT evidence, parenting interventions for people with schizophrenia or related serious mental illness have been developed. Future research should test these in RCTs in order to improve the evidence base for this population.

Renal Perfusion during Hemodialysis: Intradialytic Blood Flow Decline and Effects of Dialysate Cooling.

BACKGROUND: Residual renal function (RRF) confers survival in patients with ESRD but declines after initiating hemodialysis. Previous research shows that dialysate cooling reduces hemodialysis-induced circulatory stress and protects the brain and heart from ischemic injury. Whether hemodialysis-induced circulatory stress affects renal perfusion, and if it can be ameliorated with dialysate cooling to potentially reduce RRF loss, is unknown. METHODS: We used renal computed tomography perfusion imaging to scan 29 patients undergoing continuous dialysis under standard (36.5°C dialysate temperature) conditions; we also scanned another 15 patients under both standard and cooled (35.0°C) conditions. Imaging was performed immediately before, 3 hours into, and 15 minutes after hemodialysis sessions. We used perfusion maps to quantify renal perfusion. To provide a reference to another organ vulnerable to hemodialysis-induced ischemic injury, we also used echocardiography to assess intradialytic myocardial stunning. RESULTS: During standard hemodialysis, renal perfusion decreased 18.4% (P<0.005) and correlated with myocardial injury (r=-0.33; P<0.05). During sessions with dialysis cooling, patients experienced a 10.6% decrease in perfusion (not significantly different from the decline with standard hemodialysis), and ten of the 15 patients showed improved or no effect on myocardial stunning. CONCLUSIONS: This study shows an acute decrease in renal perfusion during hemodialysis, a first step toward pathophysiologic characterization of hemodialysis-mediated RRF decline. Dialysate cooling ameliorated this decline but this effect did not reach statistical significance. Further study is needed to explore the potential of dialysate cooling as a therapeutic approach to slow RRF decline.

Hepato-splanchnic circulatory stress: An important effect of hemodialysis.

The gastro-intestinal tract is being increasingly recognized as the site of key pathophysiological processes in the hemodialysis patient. Intestinal dysbiosis, increased intraluminal toxin production, and increased intestinal permeability are commonly observed processes which contribute to the pathogenesis of cardiovascular disease and thus elevated mortality. The acute circulatory effects of dialysis itself may contribute significantly to the development of gastrointestinal dysfunction as a result of both local and distant effects. Additionally, the liver, a relatively unknown entity in this process, has a substantial role as a functional barrier between the portal and systemic circulation and in the metabolism of pathogenic gut-derived uremic toxins. Here we summarize the evidence for acute gastro-intestinal and hepatic effects of hemodialysis and identify gaps in knowledge to date which require further study.

Effect of ultrafiltration during hemodialysis on hepatic and total-body water: an observational study.

BACKGROUND: The hepatic circulation is involved in adaptive systemic responses to circulatory stress. However, it is vulnerable to both chronic hypervolemia and cardiac dysfunction. The influence of hemodialysis (HD) and ultrafiltration (UF) upon liver water content has been understudied. We conducted a detailed pilot study to characterize the effects of HD upon liver water content and stiffness, referenced to peripheral fluid mobilization and total body water. METHODS: We studied 14 established HD patients without liver disease. Magnetic resonance imaging (MRI) together with ultrasound-based elastography and bioimpedance assessment were employed to measure hepatic water content and stiffness, body composition, and water content in the calf pre- and post-HD. RESULTS: Mean UF volume was 8.13 ± 4.4 mL/kg/hr. Fluid removal was accompanied with effective mobilization of peripheral water (measured with MRI within the thigh) from 0.85 ± 0.21 g/mL to 0.83 ± 0.18 g/mL, and reduction in total body water (38.9 ± 9.4 L to 37.4 ± 8.6 L). However, directly-measured liver water content did not decrease (0.57 ± 0.1 mL/g to 0.79 ± 0.3 m L/g). Liver water content and IVC diameter were inversely proportional (r = - 0.57, p = 0.03), a relationship which persisted after dialysis. CONCLUSIONS: In contrast to the reduced total body water content, liver water content did not decrease post-HD, consistent with a diversion of blood to the hepatic circulation, in those with signs of greater circulatory stress. This novel observation suggests that there is a unique hepatic response to HD with UF and that the liver may play a more important role in intradialytic hypotension and fluid shifts than currently appreciated.

White Female Bystanders' Responses to a Black Woman at Risk for Sexual Assault: Positive Effects of Intergroup Contact.

Although much research suggests that intergroup contact reduces prejudice, less research has examined the effects of contact on prosocial intergroup bystander behaviors. The current study examined mediators between White undergraduate women's (N = 139) contact with racial/ethnic minority group members and their intent to help a Black woman at risk for sexual assault. As expected, White women who had more frequent and higher quality contact reported greater intent to intervene. Results showed that the effect of quality intergroup contact was mediated by diversity beliefs, or the attitude that cultural heterogeneity leads to favorable outcomes. These results suggest that promoting high-quality opportunities for intergroup contact and education regarding cultural diversity could promote the safety of racially and ethnically diverse students on predominantly White campuses.

Patients with chronic kidney disease have abnormal upper gastro-intestinal tract digestive function: A study of uremic enteropathy.

BACKGROUND AND AIM: Chronic kidney disease (CKD) affects gastrointestinal (GI) function and results in numerous adaptive and maladaptive responses. Disruption of the colonic microbiome and its attendant consequences-the loss of gut barrier integrity and increased generation of uremic toxins-has become well-recognized. However, less attention has been paid to characterizing the mechanisms behind dysfunction of the upper GI tract, largely owing to the difficulty of studying small bowel function in vivo. This present study was designed to comprehensively describe upper GI function in those with advanced renal impairment. METHODS: Thirty-five non-diabetic subjects (12 CKD stage 4/5 patients, 23 healthy controls) underwent detailed GI magnetic resonance imaging (MRI) in both fasted and fed states. Upper GI function was assessed by quantification of gastric emptying and intra-luminal small bowel water. Characterization of hydration and cardiovascular status was performed at baseline. Gut barrier integrity was assessed using serum endotoxin level. RESULTS: Chronic kidney disease was associated with dysmotility (gastric half-emptying time 96 ± 32 vs 74 ± 27 min, P = 0.04) and reduced fasting and post-prandial small bowel water (36 ± 22 mL vs 78 ± 42 mL, P < 0.001), reflecting abnormal digestive secretion, and absorption. This was related to the degree of endotoxemia (r = -0.60, P = 0.04) and poorer symptom scores, but not to disease severity, arterial stiffness or hydration status. CONCLUSION: Chronic kidney disease adversely affects digestive function. Abnormalities in digestive secretion and absorption may potentially have a broad impact in the prevention and treatment of both CKD and its complications. Further study is required to assess the factors that contribute to this dysfunction in a wider CKD population.

The value of integrating pre-clinical data to predict nausea and vomiting risk in humans as illustrated by AZD3514, a novel androgen receptor modulator.

Nausea and vomiting are components of a complex mechanism that signals food avoidance and protection of the body against the absorption of ingested toxins. This response can also be triggered by pharmaceuticals. Predicting clinical nausea and vomiting liability for pharmaceutical agents based on pre-clinical data can be problematic as no single animal model is a universal predictor. Moreover, efforts to improve models are hampered by the lack of translational animal and human data in the public domain. AZD3514 is a novel, orally-administered compound that inhibits androgen receptor signaling and down-regulates androgen receptor expression. Here we have explored the utility of integrating data from several pre-clinical models to predict nausea and vomiting in the clinic. Single and repeat doses of AZD3514 resulted in emesis, salivation and gastrointestinal disturbances in the dog, and inhibited gastric emptying in rats after a single dose. AZD3514, at clinically relevant exposures, induced dose-responsive "pica" behaviour in rats after single and multiple daily doses, and induced retching and vomiting behaviour in ferrets after a single dose. We compare these data with the clinical manifestation of nausea and vomiting encountered in patients with castration-resistant prostate cancer receiving AZD3514. Our data reveal a striking relationship between the pre-clinical observations described and the experience of nausea and vomiting in the clinic. In conclusion, the emetic nature of AZD3514 was predicted across a range of pre-clinical models, and the approach presented provides a valuable framework for predicition of clinical nausea and vomiting.

Incorporation of capillary microsampling into whole body plethysmography and modified Irwin safety pharmacology studies in rats.

UNLABELLED: Limited toxicokinetic data is generated during modified Irwin screen and whole body plethysmography safety pharmacology studies, due to disturbance of primary endpoints by standard blood sampling methods. We evaluated if incorporation of microsampling would impact on data quality, as providing toxicokinetic data from main test animals could reduce the need for satellite animals. METHODS: A modified Irwin screen was performed, testing oral clonidine (0, 0.03, 0.1, or 0.3 mg/kg). One cohort of rats per dose level underwent standard blood sampling (post-4 h Irwin assessment), and another cohort underwent microsampling after the 0.5, 1, 2, 4 and 24 h Irwin assessments. The respiratory effects of oral theophylline (0 or 10 mg/kg) and oral baclofen (0 or 5 mg/kg), were tested using whole body plethysmography. Groups of animals underwent standard blood sampling (at end of recording at 4 h post-dose) or microsampling at either 0.5 h or 1 h intervals (4 or 8 microsamples, respectively). RESULTS: Microsampling did not impact on the quality of the data generated. The expected effects of clonidine on behavioural parameters, and of theophylline and baclofen on changes in ventilatory parameters were observed at a similar magnitude and duration independent of sampling method. DISCUSSION: The incorporation of multiple capillary microsamples into the modified Irwin or respiratory study did not adversely affect the primary endpoints. The capillary microsampling method is a refinement in blood sampling technique which can easily be adapted into safety pharmacology studies to generate pharmacokinetic profiles within the same animal as the primary data, thus enhancing scientific robustness and reducing the satellite animals required.

Perinatal healthcare for women at risk of children's social care involvement: a qualitative survey of professionals in England.

BACKGROUND: Women with complex health needs are more at risk of having children's social care involvement with their newborns than other mothers. Around the time of pregnancy, there are opportunities for health services to support women with these needs and mitigate the risk of mother-baby separation. Yet little is known about healthcare professionals' experiences of providing this support. METHODS: We administered an online survey to perinatal healthcare professionals across England (n=70 responders), including midwives, obstetricians, perinatal psychologists/psychiatrists and health visitors. We asked about their experiences of providing care for pregnant women with chronic physical conditions, mental health needs, intellectual/developmental disabilities and substance use disorders, who might be at risk of children's social care involvement. We conducted a framework analysis. RESULTS: We constructed five themes from participant data. These include (1) inaccessible healthcare for women with complex needs, (2) the challenges and importance of restoring trust, (3) services focusing on individuals, not families, (4) the necessity and caution around multidisciplinary support and (5) underfunded services inhibiting good practice. CONCLUSIONS: Women who are at risk of children's social care involvement will likely experience perinatal healthcare inequities. Our findings suggest that current perinatal healthcare provision for this population is inadequate and national guidelines need updated to inform support.

Parental health in the context of public family care proceedings: A scoping review of evidence and interventions.

BACKGROUND: Child protective services (CPS), or their equivalent, have statutory power to remove children from birth parents in instances of child abuse, neglect, or concerns around parenting capacity via public family care proceedings. Parents who have children subject to proceedings, 'birth parents', often have complex health and social care needs. OBJECTIVE: We aimed to review what is known about the health needs of birth parents and the interventions implemented to support these health needs. METHODS: We searched PubMed, Scopus, and grey literature using a systematic strategy of key concepts "health", "care proceedings", and "parents". We included all publications in English that reported parental health in the context of care proceedings from the 1st of January 2000 to the 1st of March 2021. RESULTS: Included studies (n = 61) reported on maternal health (57 %) or the health of both parents (40 %), with only one study reporting on fathers alone. We conceptually categorised parental health need (n = 41) into i) mental health, ii) physical health, iii) substance misuse, iv) developmental disorders, and v) reproductive health. Health inequities and poor access to services were described across all categories, with longstanding issues often pre-dating proceedings or the child's birth. All interventions supporting parental health (n = 20) were targeted at mothers, with some supporting fathers (n = 8), formally or informally. We grouped similar interventions into three types: alternative family courts, wrap-around services, and specialist advocacy/peer support. CONCLUSIONS: Parents who have children subject to care proceedings have complex health needs that pre-date CPS concerns. The studies included in our review strongly suggest that health issues are exacerbated by child removal, triggering deteriorations in mental health, poor antenatal health for subsequent pregnancies, and avoidable mortality. Findings highlight the need for targeted and timely intervention for parents to improve whole-family outcomes. There are models that have been designed, implemented, and tested using relationship-based, trauma-informed, multidisciplinary, family-focused, and long-term approaches.

Informing the development of an E-platform for monitoring wellbeing in schools: involving young people in a co-design process.

BACKGROUND: The use of new technologies and methodologies in young people's mental health research is needed to allow more frequent and reliable sampling. Mobile applications and e-platforms create exciting potential for the collection of large-scale cohort data, however there are various feasibility and ethical issues to consider. Consultation with young people is needed to inform the research agenda, and ensure these technologies are engaging, useful and safe. This article describes the process of Public and Patient Involvement (PPI) with a sample of young people in London, with the aim of i) informing the development of a mood-monitoring e-platform, and ii) providing feedback and advice for researchers developing web-based technologies in the mental health field. METHODS: A total of 26 young people were consulted across four advisory group co-design sessions. All young people were students enrolled at one of the participating London based sixth form colleges, and voluntarily attended a workshop session. Audio recordings of the sessions were analysed using a thematic analysis framework. RESULTS: We found that young people were engaged in discussions around mobile health technologies and valued the opportunity to collaborate throughout the early stages of the development process The advisory groups identified key considerations for future web-development work to encourage engagement and prolonged use, including, the promotion of trust and transparency, consideration of accessibility, provision of support, production of engaging and functional design, and acknowledgment of specific contextual influences surrounding young people's wellbeing. CONCLUSIONS: Involving young people in the development process of e-health technologies contributes to optimising the successful adoption and prolonged usage of new methodologies. The thematic map and informant examples can be used to guide researchers interested in developing web-based technologies in the mental health field and will be directly applicable to the development of a mood-monitoring e-platform.

Arts-Based Interventions for Professionals in Caring Roles During and After Crisis: A Systematic Review of the Literature.

Crisis events, such as the COVID-19 pandemic, can have a devastating effect on communities and the care professionals within them. Over recent years, arts-based interventions have helped in a wide range of crisis situations, being recommended to support the workforce during and after complex crisis but there has been no systematic review of the role of arts-based crisis interventions and whether there are cogent themes regarding practice elements and outcomes. We, therefore, conducted a systematic review to (i) define the arts-based change process used during and after crisis events, and (ii) explore the perceptions of intermediate and long-term mental health benefits of arts-based interventions for professionals in caring roles. Our search yielded six studies (all qualitative). All data were thematically aggregated and meta-synthesized, revealing seven practice elements (a safe place, focusing on strengths and protective factors, developing psychosocial competencies to support peers, emotional expression and processing, identifying and naming the impact of the crisis, using an integrative creative approach, and cultural and organizational sensitivity) applied across all six studies, as well as a range of intermediate and long-term benefits shared common features (adapting, growing, and recovering; using the community as a healing resource; reducing or preventing symptoms of stress or trauma reactions, psychophysiological homeostasis). The ways in which these studies were designed independently from one another and yet used the same practice elements in their crisis interventions indicates that there is comparability about how and why the arts-based practice elements are being used and to what effect. Our findings provide a sound basis and meaningful parameters for future research incorporating quantitative and qualitative approaches to firmly establish the effectiveness of art-based interventions, and how arts can support cultural sensitivity, acceptability and indicated outcomes, particularly those relating to stress and trauma during or following a crisis.

Decidual mesenchymal stem/stromal cell-derived extracellular vesicles ameliorate endothelial cell proliferation, inflammation, and oxidative stress in a cell culture model of preeclampsia.

Oxidative stress and endothelial dysfunction contribute substantially to the pathogenesis of preeclampsia (PE). Decidual mesenchymal stem/stromal cells (DMSC), reportedly reduce endothelial cell dysfunction and alleviate PE-like symptoms in a murine model. However, as a therapeutic strategy, the use of whole DMSC presents significant technical limitations, which may be overcome by employing DMSC-secreted extracellular vesicles (DMSC_EV). DMSC_EV restoration of endothelial dysfunction through a paracrine effect may alleviate the clinical features of PE. OBJECTIVE: To determine whether DMSC-secreted, extracellular vesicles (DMSC_EV) restore endothelial cell function and reduce oxidative stress. METHODS: DMSC were isolated from the placentae of uncomplicated term pregnancies and DMSC_EV prepared by ultracentrifugation. Human umbilical vein endothelial cells (HUVEC) were treated with bacterial lipopolysaccharide (LPS), or with serum from PE patients, to model the effects of PE. DMSC_EV were then added to treated HUVEC and their growth profiles, inflammatory state, and oxidative stress levels measured. RESULTS: DMSC_EV displayed characteristic features of extracellular vesicles. In both LPS- and PE serum-treatment models, addition of DMSC_EV significantly increased HUVEC cell attachment and proliferation, and significantly reduced production of pro-inflammatory cytokine IL-6. The addition of DMSC_EV to LPS-treated HUVEC had no significant effect on total antioxidant capacity, superoxide dismutase levels or on lipid peroxidation levels. In contrast, the addition of DMSC_EV to PE serum-treated HUVEC resulted in a significant reduction in levels of lipid peroxidation. CONCLUSION: Addition of DMSC_EV had beneficial effects in both LPS- and PE serum- treated HUVEC but the two treatment models to induce endothelial cell dysfunction showed differences. The LPS treatment of HUVEC model may not accurately model the endothelial cell dysfunction characteristic of PE. Human cell culture models of PE show that DMSC_EV improve endothelial cell dysfunction in PE, but testing in in vivo models of PE is required.

User Perspectives of Mood-Monitoring Apps Available to Young People: Qualitative Content Analysis.

BACKGROUND: Mobile health apps are increasingly available and used in a clinical context to monitor young people's mood and mental health. Despite the benefits of accessibility and cost-effectiveness, consumer engagement remains a hurdle for uptake and continued use. Hundreds of mood-monitoring apps are publicly available to young people on app stores; however, few studies have examined consumer perspectives. App store reviews held on Google and Apple platforms provide a large, rich source of naturally generated, publicly available user reviews. Although commercial developers use these data to modify and improve their apps, to date, there has been very little in-depth evaluation of app store user reviews within scientific research, and our current understanding of what makes apps engaging and valuable to young people is limited. OBJECTIVE: This study aims to gain a better understanding of what app users consider useful to encourage frequent and prolonged use of mood-monitoring apps appropriate for young people. METHODS: A systematic approach was applied to the selection of apps and reviews. We identified mood-monitoring apps (n=53) by a combination of automated application programming interface (API) methods. We only included apps appropriate for young people based on app store age categories (apps available to those younger than 18 years). We subsequently downloaded all available user reviews via API data scraping methods and selected a representative subsample of reviews (n=1803) for manual qualitative content analysis. RESULTS: The qualitative content analysis revealed 8 main themes: accessibility (34%), flexibility (21%), recording and representation of mood (18%), user requests (17%), reflecting on mood (16%), technical features (16%), design (13%), and health promotion (11%). A total of 6 minor themes were also identified: notification and reminders; recommendation; privacy, security, and transparency; developer; adverts; and social/community. CONCLUSIONS: Users value mood-monitoring apps that can be personalized to their needs, have a simple and intuitive design, and allow accurate representation and review of complex and fluctuating moods. App store reviews are a valuable repository of user engagement feedback and provide a wealth of information about what users value in an app and what user needs are not being met. Users perceive mood-monitoring apps positively, but over 20% of reviews identified the need for improvement.
