Sociodemographic and clinical predictors of delay to and length of stay with early intervention for psychosis service: findings from the CRIS-FEP study.

PURPOSE: We investigated the influence of sociodemographic and clinical characteristics on delay to early intervention service (EIS) and the length of stay (LOS) with EIS. METHODS: We used incidence data linked to the Clinical Record Interactive Search-First Episode Psychosis (CRIS-FEP) study. We followed the patients from May 2010 to March 2016. We performed multivariable Cox regression to estimate hazard ratios of delay to EIS. Negative binomial regression was used to determine LOS with EIS by sociodemographic and clinical characteristics, controlling for confounders. RESULTS: 343 patients were eligible for an EIS, 34.1% of whom did not receive the service. Overall, the median delay to EIS was 120 days (IQR; 15-1668); and the median LOS was 130.5 days (IQR 0-663). We found that women (adj.HR 0.58; 95%C I 0.42-0.78), living alone (adj.HR: 0.63; 95% CI 0.43-0.92) and ethnicity ('Other': adj.HR 0.47; 95% CI 0.23-0.98) were associated with prolonged delay to EIS. However, family involvement in help-seeking for psychosis (adj.HR 1.37; 95% CI 1.01-1.85) was strongly associated with a shorter delay to EIS. Patients who have used mental health services previously also experienced long delays to EIS. CONCLUSIONS: Our analyses highlight the link between sociodemographic status, help-seeking behaviours, and delay to EIS. Our findings also show the vulnerability faced by those with a previous mental health problem who later develop psychosis in receiving specialist treatment for psychosis. Initiatives that ameliorate indicators of social disadvantage are urgently needed to reduce health inequalities and improve clinical outcomes.

Towards understanding the nature and need of delirium guidelines across nations and cultures.

BACKGROUND: Delirium is associated with a variety of adverse healthcare outcomes but is highly predictable, preventable and treatable. For this reason, numerous guidelines have been developed for delirium recognition, prevention and management across different countries and disciplines. Although research is adduced as evidence for these guidelines, a constant finding is the lack of implementation if they exist at all. Implementation is a human behaviour that can be influenced by various factors including culture at a micro- and macro-level. Hofstede's model proposes that national cultures vary along six consistent dimensions. AIM: Using this model, we examined the nature of delirium guidelines across countries in relation to Hofstede's six cultural dimensions. METHODS: Data collected for each country on: the six dimensions of Hofstede's model, number of delirium guidelines approved by a National professional body of each country (through searching databases), the annual old-age dependency ratio for each country. RESULTS: Sixty-four countries had the completed six dimensions of Hofstede's model. Twenty of them (31%) had one or more delirium guidelines. The total number of different delirium guidelines was 45. Countries with formal delirium guidelines have significantly lower power distance among their members, are more individualistic societies, have lower levels of uncertainty avoidance and higher old-age dependency ratio compared to those without delirium guidelines. DISCUSSION/CONCLUSION: The development and implementation of delirium guidelines vary across countries. Specific combinations of cultural dimensions influence the production of delirium guidelines. Understanding these important cultural differences can facilitate more widespread acceptance and implementation of guidelines.

Navigating power dynamics in engaging communities in end-of-life issues - Lessons learned from developing community-based intergenerational arts initiatives about death and loss.

Lack of community engagement in end-of-life issues and age-segregation in Swedish society motivated us to develop Studio DöBra, a community-based intergenerational arts initiative to support community engagement in end-of-life issues and develop intergenerational meeting places. Representatives from several community organizations formed a project group with first author MK, to develop Studio DöBra. Based on analysis of exploratory interviews with professionals involved in other, similar initiatives and data from Studio DöBra development, we discuss challenges related to power dynamics in developing initiatives to engage communities in end-of-life issues, and how these can inform the development of similar initiatives.

Sociodemographic factors associated with routine outcome monitoring: a historical cohort study of 28,382 young people accessing child and adolescent mental health services.

BACKGROUND: Patient-reported outcome measures (PROMs) are important tools to inform patients, clinicians and policy-makers about clinical need and the effectiveness of any given treatment. Consistent PROM use can promote early symptom detection, help identify unexpected treatment responses and improve therapeutic engagement. Very few studies have examined associations between patient characteristics and PROM data collection. METHODS: We used the electronic mental health records for 28,382 children and young people (aged 4-17 years) accessing Child and Adolescent Mental Health Services (CAMHS) across four South London boroughs between the 1st of January 2008 to the 1st of October 2017. We examined the completion rates of the caregiver Strengths and Difficulties Questionnaire (SDQ), a ubiquitous PROM for CAMHS at baseline and 6-month follow-up. RESULTS AND CONCLUSIONS: SDQs were present for approximately 40% (n = 11,212) of the sample at baseline, and from these, only 8% (n = 928) had a follow-up SDQ. Patterns of unequal PROM collection by sociodemographic factors were identified: males were more likely (aOR 1.07, 95% CI 1.01-1.13), whilst older age (aOR 0.87, 95% CI 0.87-0.88), Black (aOR 0.79 95% CI 0.74-0.84) and Asian ethnicity (aOR 0.75 95% CI 0.66-0.86) relative to White ethnicity, and residence within the most deprived neighbourhood (aOR 0.87 95% CI 0.80-0.94) were less likely to have a record of baseline SDQ. Similar results were found in the sub-group (n = 11,212) with follow-up SDQ collection. Our findings indicate systematic differences in the currently available PROMS data and highlights which groups require increased focus if we are to gain equitable PROM collection. We need to ensure representative PROM collection for all individuals accessing treatment, regardless of ethnic or socioeconomic background; biased data have adverse ramifications for policy and service level decision-making.

Regulation of food intake by astrocytes in the brainstem dorsal vagal complex.

A role for glial cells in brain circuits controlling feeding has begun to be identified with hypothalamic astrocyte signaling implicated in regulating energy homeostasis. The nucleus of the solitary tract (NTS), within the brainstem dorsal vagal complex (DVC), integrates vagal afferent information from the viscera and plays a role in regulating food intake. We hypothesized that astrocytes in this nucleus respond to, and influence, food intake. Mice fed high-fat chow for 12 hr during the dark phase showed NTS astrocyte activation, reflected in an increase in the number (65%) and morphological complexity of glial-fibrillary acidic protein (GFAP)-immunoreactive cells adjacent to the area postrema (AP), compared to control chow fed mice. To measure the impact of astrocyte activation on food intake, we delivered designer receptors exclusively activated by designer drugs (DREADDs) to DVC astrocytes (encompassing NTS, AP, and dorsal motor nucleus of the vagus) using an adeno-associated viral (AAV) vector (AAV-GFAP-hM3Dq_mCherry). Chemogenetic activation with clozapine-N-oxide (0.3 mg/kg) produced in greater morphological complexity in astrocytes and reduced dark-phase feeding by 84% at 4 hr postinjection compared with vehicle treatment. hM3Dq-activation of DVC astrocytes also reduced refeeding after an overnight fast (71% lower, 4 hr postinjection) when compared to AAV-GFAP-mCherry expressing control mice. DREADD-mediated astrocyte activation did not impact locomotion. hM3Dq activation of DVC astrocytes induced c-FOS in neighboring neuronal feeding circuits (including in the parabrachial nucleus). This indicates that NTS astrocytes respond to acute nutritional excess, are involved in the integration of peripheral satiety signals, and can reduce food intake when activated.

Continuity of care and clinical outcomes in the community for people with severe mental illness.

BACKGROUND: High continuity of care is prized by users of mental health services and lauded in health policy. It is especially important in long-term conditions like schizophrenia. However, it is not routinely measured, and therefore not often evaluated when service reorganisations take place. In addition, the impact of continuity of care on clinical outcomes is unclear.AimsWe set out to examine continuity of care in people with schizophrenia, and to relate this to demographic variables and clinical outcomes. METHOD: Pseudoanonymised community data from 5552 individuals with schizophrenia presenting over 11 years were examined for changes in continuity of care using the numbers of community teams caring for them and the Modified Modified Continuity Index (MMCI). These and demographic variables were related to clinical outcomes measured with the Health of the Nation Outcome Scales (HoNOS). Data were analysed using generalised estimating equations and multivariate marginal models. RESULTS: There was a significant decline in MMCI and significant worsening of HoNOS total scores over 11 years. Higher (worse) HoNOS scores were significantly and independently related to older age, later years and both lower MMCI and more teams caring for the individual in each year. Most HoNOS scales contributed to the higher total scores. CONCLUSIONS: There is evidence of declining continuity of care in this 11-year study of people with schizophrenia, and of an independent effect of this on worse clinical outcomes. We suggest that this is related to reorganisation of services.Declaration of interestNone.

Development, validation and initial evaluation of patient-decision aid (SUI-PDA©) for women considering stress urinary incontinence surgery.

INTRODUCTION AND HYPOTHESIS: Following the design, face validation and publication of a novel PDA for women considering SUI surgery, the main objective of the study is to evaluate the usefulness of SUI-PDA© by using a validated tool to obtain patient feedback. METHODS: From July 2018 to March 2019, the PDA, already incorporated into the patient care pathway, was objectively evaluated using the Decisional Conflict Scale (DCS) to determine patients' views. Patients recorded their values and reasons for requests and declines of treatment. The total DCS score, scores from each DCS subgroup and individual patient responses were calculated and analysed. RESULTS: The mean age of the first 20 patients to complete the DCS was 54 years, the mean BMI was 30.1 and the median parity was 3. The average total DCS score was only 9.29 out of 100 (range 0-29.69) suggesting that the PDA was quite useful for patients considering SUI surgery. Overall, the PDA had largely favourable responses across all five DCS subgroups. The 'informed' subgroup had the best score (6.67) while the 'uncertainty' subgroup had the least favourable score (14.58). Despite the procedure pause, the mesh tape option remained on the PDA; however, no patient had chosen this option, with a large proportion citing 'safety' issues as the main reason. Bulking agent injections were the most popular choice (40.0%) and the most commonly performed procedures (50.0%) mainly because of quicker 'recovery'. The second most popular participant choice was colposuspension (35.0%) followed by autologous fascial sling (25.0%), with women citing 'efficacy' as the main reason behind their choice. CONCLUSION: SUI-PDA© was reported by patients and clinicians to be useful with clinical decision-making for SUI surgery. Further validation in a larger patient group is underway.

Synchronous diversification of Sulawesi's iconic artiodactyls driven by recent geological events.

The high degree of endemism on Sulawesi has previously been suggested to have vicariant origins, dating back to 40 Ma. Recent studies, however, suggest that much of Sulawesi's fauna assembled over the last 15 Myr. Here, we test the hypothesis that more recent uplift of previously submerged portions of land on Sulawesi promoted diversification and that much of its faunal assemblage is much younger than the island itself. To do so, we combined palaeogeographical reconstructions with genetic and morphometric datasets derived from Sulawesi's three largest mammals: the babirusa, anoa and Sulawesi warty pig. Our results indicate that although these species most likely colonized the area that is now Sulawesi at different times (14 Ma to 2-3 Ma), they experienced an almost synchronous expansion from the central part of the island. Geological reconstructions indicate that this area was above sea level for most of the last 4 Myr, unlike most parts of the island. We conclude that emergence of land on Sulawesi (approx. 1-2 Myr) may have allowed species to expand synchronously. Altogether, our results indicate that the establishment of the highly endemic faunal assemblage on Sulawesi was driven by geological events over the last few million years.

Not just things: the roles of objects at the end of life.

While the study of objects in care contexts is an emerging research field, it is largely overlooked in end of life (EoL) care. In this study, we empirically and inductively explore the roles of objects at the EoL from the perspective of bereaved family members. Open individual interviews were conducted with 25 family members recruited from palliative in-patient and homecare units, as well as residential care facilities. After verbatim transcription, the interviews were analysed thematically. Based on these interviews, we conceptualise the roles of objects as relating to temporality, transformations of the everyday, and care. Through analysis we offer two main insights, the first relating to interdependency between objects and people, and the second to the recognition of objects as simultaneously flexible and stable in this interdependent relationship. The capacity and challenge of objects as part of EoL care lies in their ability to encompass various viewpoints and relationships simultaneously. This might provide valuable insights for staff caring for dying persons and their families. We propose that staff's ability to navigate objects in care practices could be meaningful in supporting the relationships between individuals in EoL situations.

Routine mental health outcome measurement in the UK.

This paper offers a short history of routine clinical outcomes measurement (RCOM) in UK mental health services. RCOM developments in primary and secondary care are described, with reference to measures currently in widespread use or likely to be implemented. Assessment procedure and completion rates are discussed. Some of the forces operating in this field are enumerated. Comparison is made with UK attempts at routine outcomes measurement in public education. This field is thus reviewed for lessons for RCOM, and opportunities and challenges considered.

The breath shape controls intonation of mouse vocalizations.

Intonation in speech is the control of vocal pitch to layer expressive meaning to communication, like increasing pitch to indicate a question. Also, stereotyped patterns of pitch are used to create distinct sounds with different denotations, like in tonal languages and, perhaps, the 10 sounds in the murine lexicon. A basic tone is created by exhalation through a constricted laryngeal voice box, and it is thought that more complex utterances are produced solely by dynamic changes in laryngeal tension. But perhaps, the shifting pitch also results from altering the swiftness of exhalation. Consistent with the latter model, we describe that intonation in most vocalization types follows deviations in exhalation that appear to be generated by the re-activation of the cardinal breathing muscle for inspiration. We also show that the brainstem vocalization central pattern generator, the iRO, can create this breath pattern. Consequently, ectopic activation of the iRO not only induces phonation, but also the pitch patterns that compose most of the vocalizations in the murine lexicon. These results reveal a novel brainstem mechanism for intonation.

A Computed Tomographic Study of the Molar Teeth of Babyrousa spp.

A photographic and computed tomography (CT) scanning study was carried out on 295 molar teeth of 18 adult male Babyrousa babyrussa skulls and 8 skulls of Babyrousa celebensis including seven adult males and one adult female. The occlusal morphology of the permanent maxillary and mandibular molar teeth of B. babyrussa was very similar to that of B. celebensis. Most B. babyrussa maxillary molar teeth had six roots, with small numbers of teeth having four, five or seven roots. A similar pattern was suggested in B. celebensis. Mandibular molar teeth had between four and eight roots. Tooth roots of maxillary and mandibular first and second molar teeth were largely tapering, rod-like structures. The roots of the right and left maxillary third molar teeth had a more complex arrangement; some were inserted almost vertically into the maxilla; others were orientated in a more distal direction. The mesial and distal roots were splayed in appearance. The right and left mandibular third molar tooth roots retained elements of the open 'C' shape and were generally orientated distally. The pulp chambers were arched to fit under the main cusps in all molar teeth. Pulp canals were variable in number.

Impact of the demand for 'proxy assent' on recruitment to a randomised controlled trial of vaccination testing in care homes.

Legal frameworks are in place to protect those who lack the capacity to consent to research, such as the Mental Capacity Act in the UK. Assent is sought instead from a proxy, usually a relative. However, the same legislation may, perversely, affect the welfare of those who lack capacity and of others by hindering the process of recruitment into otherwise potentially beneficial research. In addition, the onus of responsibility is moved from those who know most about the study (ie, the scientific community) to those who know less (the proxies). In this paper, we describe the characteristics of a sample at different stages of the recruitment process of an influenza vaccine-based randomised control trial in elderly care home residents (the FEVER study). 62% (602/968) of potential subjects lacked capacity but only 29% (80/277) of those actually randomised. Older age, being female and living in an Elderly Mentally Ill care home were the only variables associated with lacking capacity. Considering this was a study based in a care home setting where the prevalence of dementia approximates 80%, the trial, like many others, was thus significantly biased. We believe that difficulties seeking proxy assent contributed significantly to this problem. Further thought should be given to how assent to enter research for those who lack capacity should be provided, and we suggest avenues for further discussion such as independent risk/benefit expert panels.

Validation of the Greek version of the Health of the Nation Outcome Scales for Elderly People (HoNOS65+, version 3).

OBJECTIVES: There is a growing need for evaluation of the results of mental health services and clinical treatment in older people, but evidence for effectiveness is limited in Greece. The Health of the Nations Outcome Scales for Elderly People (HoNOS65+) are promising instruments for the assessment of mental, physical and social health in older persons. They have been translated into the Greek language but have not been validated. The aim was to assess the inter-rater reliability, intraclass correlation, concurrent validity, internal consistency and sensitivity to change of HoNOS65+ in a Greek sample of older people with mental health problems. METHOD: Two samples, one of inpatients in a psychiatric hospital and the other of older people living in the community were used. In order to test the extent to which the HoNOS65+ were sensitive to change the first sample was reassessed after two months and the second after three months. For each participant HoNOS65+ were completed by two independent raters, and the clinician rated blindly each participant on the Stockton Geriatric Rating Scale and a scale which measured behavioural, physical, cognitive and emotional status. RESULTS: In both groups (inpatients n = 50, community n = 65), the inter-rater reliability, intraclass correlation and concurrent validity were high while internal consistency of the scales taken together was low. At reassessment in 98 participants, HoNOS65+ showed changes comparable to clinician ratings. CONCLUSION: The Greek version of HoNOS65+ can achieve high levels of reliability, validity and sensitivity to change for measuring outcomes in older people with mental health problems.

The breath shape controls intonation of mouse vocalizations.

Intonation in speech is the control of vocal pitch to layer expressive meaning to communication, like increasing pitch to indicate a question. Also, stereotyped patterns of pitch are used to create distinct "words", like the ten sounds in the murine lexicon. A basic tone is created by exhalation through a constricted laryngeal voice box, and it is thought that more complex utterances are produced solely by dynamic changes in laryngeal tension. But perhaps, the shifting pitch also results from altering the power of exhalation. Consistent with the latter model, we describe that intonation in many adult murine vocalizations follows deviations in exhalation and that the brainstem vocalization central pattern generator, the iRO, can create this breath pattern. Consequently, ectopic activation of the iRO not only induces phonation, but also the pitch patterns that compose most of the vocalizations in the murine lexicon. These results reveal a novel brainstem mechanism for intonation.

Using experience-based co-design (EBCD) to develop high-level design principles for a visual identification system for people with dementia in acute hospital ward settings.

OBJECTIVES: We tested a modified co-design process to develop a set of high-level design principles for visual identification systems (VIS) for hospitalised people with dementia. DESIGN: We designed and ran remote workshops in three phases with carers of people with dementia and healthcare staff. In phase 1 we presented participants with scenarios based on findings from prior research, prompting participants to discuss their own experiences of VIS. Phase 2 used more future-focused scenarios, prompting participants to co-design improved VIS. In phase 3, a set of provisional design principles developed from our analysis of phases 1 and 2 data were discussed. SETTING: Online workshops. PARTICIPANTS: A total of 26 carers and 9 healthcare staff took part in a pilot and three separate workshops. RESULTS: We identified a set of six dementia-friendly design principles for improving the effectiveness of VIS: (1) The hospital trust provides a professionally-trained workforce and an appropriate culture of care; (2) the symbol is easily recognisable and well understood; (3) key personal information is readily available and accessible; (4) key personal information is integrated into the electronic patient record; (5) relatives and carers are involved in providing key information and monitoring care; (6) the principles need to function as a system to be successful. Participants suggested that, in addition to the use of an identifier and key personal information, professional standards training, effective information and records management and improved means to involve carers and/or families were key to the effective operation of VIS, leading us to expand a narrow understanding of a VIS. CONCLUSION: Using a scenario-led co-design approach can help trigger useful discussions with staff and carer groups, identify current problems with VIS and develop a set of high-level design principles for their improvement. These principles reveal day-to-day frictions that require further attention and resolution.

Impact of chemogenetic activation of dorsal vagal complex astrocytes in mice on adaptive glucoregulatory responses.

The dorsal vagal complex (DVC) regulates diverse aspects of physiology including food intake and blood glucose homeostasis. Astrocytes play an active role in regulating DVC function and, by extension, physiological parameters. DVC astrocytes in ex vivo slices respond to low tissue glucose. The response of neurons to low glucose is conditional on intact astrocyte signalling in slice preparations, suggesting astrocytes are primary sensors of glucose deprivation (glucoprivation). Based on these published findings we hypothesised that in vivo DVC astrocyte manipulation with chemogenetics would be sufficient to alter physiological responses that control blood glucose. We found that 2-h after systemic 2-DG-induced glucoprivation there were no observable changes in morphology of glial fibrillary acidic protein (GFAP)-immunoreactive DVC cells, specifically those in the nucleus of the solitary tract (NTS). Chemogenetic activation of DVC astrocytes was sufficient to suppress nocturnal food intake by reducing both meal size and meal number and this manipulation also suppressed 2-DG-induced glucoprivic food intake. Chemogenetic activation of DVC astrocytes did not increase basal blood glucose nor protect against insulin-induced hypoglycaemia. In male mice, chemogenetic DVC astrocyte activation did not alter glucose tolerance. In female mice, the initial glucose excursion was reduced in a glucose tolerance test, suggesting enhanced glucose absorption. Based on our data and published work, we propose that DVC astrocytes may play an indispensable homeostatic role, that is, are necessary to maintain the function of glucoregulatory neuronal circuitry, but alone their bulk activation is not sufficient to result in adaptive glucoregulatory responses. It is possible that there are state-dependent effects and/or DVC astrocyte subsets that have this specialised role, but this was unresolvable using the experimental approaches employed here.

Evaluation of the impact of implementing the prone jackknife position for the perineal phase of abdominoperineal excision of the rectum.

BACKGROUND: Abdominoperineal excision of rectum has been associated with poor oncological specimens and high local recurrence rates in comparison with restorative surgery. The role of recent changes in operative position has yet to be evaluated. OBJECTIVES: This study aimed to determine whether a change in the perineal phase from the Lloyd-Davies position to the prone jackknife position might improve excision margins and oncological outcomes. METHODS: A single-institution review of a prospectively maintained database comparing the quality of excision and oncological outcomes after abdominoperineal excision in conventional and prone position was performed. Consecutive abdominoperineal excisions performed for adenocarcinoma of the rectum between January 1999 and April 2008 were included. RESULTS: Abdominoperineal excision cases were assessed including 63 in the Lloyd-Davies position and 58 in the prone jackknife position. The 5-year local recurrence rate was 5% in the prone jackknife group in comparison with 23% in the Lloyd-Davies group (p = 0.03) by life table analysis. For local recurrence, the most significant and independent risk factors were a favorable effect of having the patient in the prone jackknife position for the perineal phase of abdominoperineal excision (HR 0.2; 95% CI 0.04-0.81) and, unfavorably, a positive circumferential resection margin (HR 7.1; 95% CI 2.4-20). Lymph node involvement (N2) was an independent risk factor for overall survival (HR 4.6; 95% CI 2.1-9.5) and relapse of disease (HR 4.0; 95% CI 0.7-9.4). LIMITATIONS: This study has some limitations because it is a retrospective review of a prospective database. CONCLUSION: These data suggest that the rate of local recurrence after abdominoperineal excision may be lowered by adaptation of the prone jackknife position.
