When does shared decision making is adopted in psychiatric clinical practice? Results from a European multicentric study.

To identify factors associated with the use of shared decision making in routine mental health care in a large multicenter European study. Data have been collected within the study "Clinical decision making and outcome in routine care for people with severe mental illness" (CEDAR), which is a naturalistic, longitudinal, observational study carried out in six European countries. Patients with a severe mental illness attending outpatient units and their treating clinicians have been recruited. Clinicians' Clinical Decision Making (CDM) styles have been explored through the Clinical Decision Making Style Scale. Patients' clinical and social outcomes have been assessed through validated assessment instruments. The sample consisted of 588 patients and 213 professionals. Professionals were mainly psychiatrists (35.7%), nurses (21.6%), support workers, social workers or occupational therapists (24.9%), psychologists (9.9%) or trainees in psychiatry (4.7%). In the majority of cases, clinicians adopted a shared CDM style. Shared CDM was more frequently adopted with patients with psychotic disorders, with a better quality of life and social functioning. At multivariate analyses, the likelihood of adopting shared decision making increased in patients with higher levels of interpersonal relationships' skills (p < 0.05) and global functioning (p < 0.01). On the contrary, being a trainee in psychiatry reduced the likelihood of adopting shared CDM (p < 0.008). Shared decision making has been adopted mainly when patients have a better functioning and less severe clinical symptomatology and by less trained clinicians, differently from national and international recommendations. More efforts should be made to implement interventions to promote shared CDM, with a specific focus for trainees in psychiatry.

Rates and occupational characteristics of international seafarers with mental illness.

BACKGROUND: Seafarers enable 90% of global commerce, working in isolation from social support and medical care. While occupational conditions of isolation may suggest possible excess risk of mental illness and suicide, research on seafarer mental illness is limited. AIMS: To describe seafarers with mental illness and associated incidence rates in a large population of international seafarers. METHODS: We used mental illness claims data from a large international marine insurance provider arising from working seafarers during the years 2007-15. We used descriptive statistics and calculated mental illness incidence rates in this seafarer population. RESULTS: There were 278 seafarer mental illness claims in the study data. Claims were more often reported in deck workers (46%) and ratings (58%). The crude mental illness rate was 3.9 per 100 000 person-years. CONCLUSIONS: Using objective data on a large seafaring population, our analysis highlights the important issue of mental illness in this isolated and underserved international workforce. The low observed mental illness claims rate is likely due to the high threshold for claims reporting.

Recovery practice in community mental health teams: national survey.

BACKGROUND: There is consensus about the importance of 'recovery' in mental health services, but the link between recovery orientation of mental health teams and personal recovery of individuals has been underresearched. AIMS: To investigate differences in team leader, clinician and service user perspectives of recovery orientation of community adult mental health teams in England. METHOD: In six English mental health National Health Service (NHS) trusts, randomly chosen community adult mental health teams were surveyed. A random sample of ten patients, one team leader and a convenience sample of five clinicians were surveyed from each team. All respondents rated the recovery orientation of their team using parallel versions of the Recovery Self Assessment (RSA). In addition, service users also rated their own personal recovery using the Questionnaire about Processes of Recovery (QPR). RESULTS: Team leaders (n = 22) rated recovery orientation higher than clinicians (n = 109) or patients (n = 120) (Wald(2) = 7.0, P = 0.03), and both NHS trust and team type influenced RSA ratings. Patient-rated recovery orientation was a predictor of personal recovery (b = 0.58, 95% CI 0.31-0.85, P<0.001). Team leaders and clinicians with experience of mental illness (39%) or supporting a family member or friend with mental illness (76%) did not differ in their RSA ratings from other team leaders or clinicians. CONCLUSIONS: Compared with team leaders, frontline clinicians and service users have less positive views on recovery orientation. Increasing recovery orientation may support personal recovery.

Empowerment and satisfaction in a multinational study of routine clinical practice.

OBJECTIVE: Decision-making between mental health clinicians and patients is under-researched. We tested whether mental health patients are more satisfied with a decision made (i) using their preferred decision-making style and (ii) with a clinician with the same decision-making style preference. METHOD: As part of the CEDAR Study (ISRCTN75841675), a convenience sample of 445 patients with severe mental illness from six European countries were assessed for desired clinical decision-making style (rated by patients and paired clinicians), decision-specific experienced style and satisfaction. RESULTS: Patients who experienced more involvement in decision-making than they desired rated higher satisfaction (OR=2.47, P=0.005, 95% CI 1.32-4.63). Decisions made with clinicians whose decision-making style preference was for more active involvement than the patient preference were rated with higher satisfaction (OR=3.17, P=0.003, 95% CI 1.48-6.82). CONCLUSION: More active involvement in decision-making than the patient stated as desired was associated with higher satisfaction. A clinical orientation towards empowering, rather than shared, decision-making may maximise satisfaction.

The presence of disseminated tumour cells in the bone marrow is inversely related to circulating free DNA in plasma in breast cancer dormancy.

BACKGROUND: The aim of this study was to gain insight into breast cancer dormancy by examining different measures of minimal residual disease (MRD) over time in relation to known prognostic factors. METHODS: Sixty-four primary breast cancer patients on follow-up (a median of 8.3 years post surgery) who were disease free had sequential bone marrow aspirates and blood samples taken for the measurement of disseminated tumour cells (DTCs), circulating tumour cells (CTCs) by CellSearch and qPCR measurement of overlapping (96-bp and 291-bp) amplicons in circulating free DNA (cfDNA). RESULTS: The presence of CTCs was correlated with the presence of DTCs measured by immunocytochemistry (P=0.01) but both were infrequently detected. Increasing cfDNA concentration correlated with ER, HER2 and triple-negative tumours and high tumour grade, and the 291-bp amplicon was inversely correlated with DTCs measured by CK19 qRT-PCR (P=0.047). CONCLUSION: Our results show that breast cancer patients have evidence of MRD for many years after diagnosis despite there being no overt evidence of disease. The inverse relationship between bone marrow CK19 mRNA and the 291-bp amplicon in cfDNA suggests that an inverse relationship between a measure of cell viability in the bone marrow (DTCs) and cell death in the plasma occurs during the dormancy phase of breast cancer.

Measures of the recovery orientation of mental health services: systematic review.

PURPOSE: The review aimed to (1) identify measures that assess the recovery orientation of services; (2) discuss how these measures have conceptualised recovery, and (3) characterise their psychometric properties. METHODS: A systematic review was undertaken using seven sources. The conceptualisation of recovery within each measure was investigated by rating items against a conceptual framework of recovery comprising five recovery processes: connectedness; hope and optimism; identity; meaning and purpose; and empowerment. Psychometric properties of measures were evaluated using quality criteria. RESULTS: Thirteen recovery orientation measures were identified, of which six met eligibility criteria. No measure was a good fit with the conceptual framework. No measure had undergone extensive psychometric testing and none had data on test-retest reliability or sensitivity to change. CONCLUSIONS: Many measures have been developed to assess the recovery orientation of services. Comparisons between the measures were hampered by the different conceptualisations of recovery used and by the lack of uniformity on the level of organisation at which services were assessed. This situation makes it a challenge for services and researchers to make an informed choice on which measure to use. Further work is needed to produce measures with a transparent conceptual underpinning and demonstrated psychometric properties.

Summary of the British Thoracic Society guidelines for advanced diagnostic and therapeutic flexible bronchoscopy in adults.

This new guideline covers the rapidly advancing field of interventional bronchoscopy using flexible bronchoscopy. It includes the use of more complex diagnostic procedures such as endobronchial ultrasound, interventions for the relief of central airway obstruction due to malignancy and the recent development of endobronchial therapies for chronic obstructive pulmonary disease and asthma. The guideline aims to help all those who undertake flexible bronchoscopy to understand more about this important area. It also aims to inform respiratory physicians and other specialists dealing with lung cancer of the procedures possible in the management and palliation of central airway obstruction. The guideline covers transbronchial needle aspiration and endobronchial ultrasound-guided transbronchial needle aspiration, electrocautery/diathermy, argon plasma coagulation and thermal laser, cryotherapy, cryoextraction, photodynamic therapy, brachytherapy, tracheobronchial stenting, electromagnetic navigation bronchoscopy, endobronchial valves for emphysema and bronchial thermoplasty for asthma.

Improving standards in flexible bronchoscopy for lung cancer.

Can the detection rate of flexible bronchoscopy for lung cancer be increased by a series of simple quality improvement measures? Bronchoscopy-associated clinical parameters were prospectively recorded between 2001 and 2007 in patients with suspected lung malignancy. The detection rate of bronchoscopy, diagnostic yield of each biopsy modality and the possible impact of different service-improvement measures were assessed. 746 bronchoscopies were performed in 704 patients. The detection rate of bronchoscopy for malignancy was 83.6%, and increased over time (67.3% detection rate in 2001 (95% CI 52.9-79.7), 89.7% detection rate in 2007 (95% CI 81.3-95.2); p<0.001). Detection rate increased for bronchoscopically visible (75.0% in 2001 to 94.5% in 2007) and non-visible tumours (41.7% in 2001 to 81.2% in 2007; p<0.001 for both analyses). Prior computed tomography availability was associated with a higher diagnostic yield that did not reach statistical significance. Logistic regression analysis identified tumour visibility, year of study, use of transbronchial needle aspiration and pathologist identity as independent predictors of a positive diagnosis. A significant increase in bronchoscopic detection rate for malignancy occurred in association with a number of simple improvement measures.

Developing and comparing methods for measuring the content of care in mental health services.

BACKGROUND: Measurement of what happens in mental health services is needed to describe services, identify variation in care provision and understand service outcomes. However, there is no consensus about appropriate methods or measures for content of care. Previous research has primarily used a single information source and prioritised staff over patient perspectives on content of care. This study aims to enhance understanding of how to measure content of care by developing and evaluating four instruments, each using a different measurement method. METHODS: Development is described by four instruments-CaSPAR, CaRICE, CCCQ-S and CCCQ-P-which use researcher observation, staff-report and patient-report to measure the intensity and nature of care at services. Inter-rater reliability of CaRICE and CCCQ-S was investigated. Concordance between staff and patient perspectives was explored through assessing inter-rater agreement of CCCQ-S and CCCQ-P questionnaires. The convergence of data from the measures collected in an inpatient multi-site study was investigated. RESULTS: CaRICE demonstrated good inter-rater reliability (κ = 0.71). CCCQ-S inter-rater reliability was poor. Concordance between staff and patient reports was low: there was a trend for patients to report less care received than staff reported had been provided. Results from CaSPAR, CaRICE and CCCQ-P exhibited divergence, indicating possible differences in patient, staff and researcher perspectives. DISCUSSION: Information about content of care should be sought as close as possible to the point of delivery. There may be differing, valid perspectives about care provided by services. Further development of methods to measure content of care is required. Meanwhile, a multi-methods approach should be adopted, which allows inclusion of different perspectives (specifically including the patient's perspective) and triangulation of results from different measurement methods. CaSPAR, CaRICE and CCCQ-P can provide multi-perspective content of care measurement in inpatient services.

Personal Recovery in People With a Psychotic Disorder: A Systematic Review and Meta-Analysis of Associated Factors.

Background: Personal recovery (PR) is a subjective, multidimensional concept, and quantitative research using PR as an outcome is rapidly increasing. This systematic review is intended to support the design of interventions that contribute to PR in psychotic disorders, by providing an overview of associated factors and their weighted importance to PR: clinical factors, social factors, and socio-demographic characteristics are included, and factors related to the concept of PR (organized into CHIME dimensions). Methods: A systematic literature search was conducted from inception to March 2020. Quantitative studies that had used a validated questionnaire assessing the concept of PR were included. Mean effect sizes for the relationship between PR-scale total scores and related factors were calculated using meta-analyses. Sources of heterogeneity were examined using meta-regression tests. Results: Forty-six studies, that used (a total of) eight PR measures, showed that in clinical factors, affective symptoms had a medium negative association with PR-scale total scores (r = -0.44, 95%CI -0.50 to -0.37), while positive, negative and general symptoms had small negative correlations. No association was found with neuro-cognition. Social factors (support, work and housing, and functioning) showed small positive correlations. Gender and age differences had barely been researched. Large associations were found for PR-scale total scores with the CHIME dimensions hope (r = 0.56, 95%CI 0.48-0.63), meaning in life (r = 0.48, 95%CI 0.38-0.58) and empowerment (r = 0.53, 95%CI 0.42-0.63); while medium associations were found with connectedness (r = 0.34, 95%CI 0.43-0.65) and identity (r = 0.43, 95%CI 0.35-0.50). Levels of heterogeneity were high, sources included: the variety of PR measures, variations in sample characteristics, publication bias, variations in outcome measures, and cultural differences. Discussion: Most interventions in mental healthcare aim to reduce symptoms and improve functioning. With regard to stimulating PR, these interventions may benefit from also focusing on enhancing hope, empowerment, and meaning in life. The strength of these findings is limited by the challenges of comparing separate CHIME dimensions with questionnaires assessing the concept of PR, and by the high levels of heterogeneity observed. Future research should focus on the interaction between elements of PR and clinical and social factors over time.

Prevalence of beryllium sensitization among aluminium smelter workers.

BACKGROUND: Beryllium exposure occurs in aluminium smelters from natural contamination of bauxite, the principal source of aluminium. AIMS: To characterize beryllium exposure in aluminium smelters and determine the prevalence rate of beryllium sensitization (BeS) among aluminium smelter workers. METHODS: A population of 3185 workers from nine aluminium smelters owned by four different aluminium-producing companies were determined to have significant beryllium exposure. Of these, 1932 workers participated in medical surveillance programmes that included the serum beryllium lymphocyte proliferation test (BeLPT), confirmation of sensitization by at least two abnormal BeLPT test results and further evaluation for chronic beryllium disease in workers with BeS. RESULTS: Personal beryllium samples obtained from the nine aluminium smelters showed a range of <0.01-13.00 µg/m(3) time-weighted average with an arithmetic mean of 0.25 µg/m(3) and geometric mean of 0.06 µg/m(3). Nine workers were diagnosed with BeS (prevalence rate of 0.47%, 95% confidence interval = 0.21-0.88%). CONCLUSIONS: BeS can occur in aluminium smelter workers through natural beryllium contamination of the bauxite and further concentration during the refining and smelting processes. Exposure levels to beryllium observed in aluminium smelters are similar to those seen in other industries that utilize beryllium. However, compared with beryllium-exposed workers in other industries, the rate of BeS among aluminium smelter workers appears lower. This lower observed rate may be related to a more soluble form of beryllium found in the aluminium smelting work environment as well as the consistent use of respiratory protection.

Alternatives to standard acute in-patient care in England: short-term clinical outcomes and cost-effectiveness.

BACKGROUND: Outcomes following admission to residential alternatives to standard in-patient mental health services are underresearched. AIMS: To explore short-term outcomes and costs of admission to alternative and standard services. METHOD: Health of the Nation Outcome Scales (HoNOS), Threshold Assessment Grid (TAG), Global Assessment of Functioning (GAF) and admission cost data were collected for six alternative services and six standard services. RESULTS: All outcomes improved during admission for both types of service (n = 433). Adjusted improvement was greater for standard services in scores on HoNOS (difference 1.99, 95% CI 1.12-2.86), TAG (difference 1.40, 95% CI 0.39-2.51) and GAF functioning (difference 4.15, 95% CI 1.08-7.22) but not GAF symptoms. Admissions to alternatives were 20.6 days shorter, and hence cheaper (UK pound3832 v. pound9850). Standard services cost an additional pound2939 per unit HoNOS improvement. CONCLUSIONS: The absence of clear-cut advantage for either type of service highlights the importance of the subjective experience and longer-term costs.

Alternatives to standard acute in-patient care in England: differences in content of care and staff-patient contact.

BACKGROUND: Differences in the content of care provided by acute in-patient mental health wards and residential crisis services such as crisis houses have not been researched. AIMS: To compare planned and actual care provided at alternative and standard acute wards and to investigate the relationship between care received and patient satisfaction. METHOD: Perspectives of stakeholders, including local service managers, clinicians and commissioners, were obtained from 23 qualitative interviews. Quantitative investigation of the care provided at four alternative and four standard services was undertaken using three instruments developed for this study. The relationship of care received to patient satisfaction was explored. RESULTS: No significant difference was found in intensity of staff-patient contact between alternative and standard services. Alternative services provided more psychological and less physical and pharmacological care than standard wards. Care provision may be more collaborative and informal in alternative services. All measured types of care were positively associated with patient satisfaction. Measured differences in the care provided did not explain the greater acceptability of community alternatives. CONCLUSIONS: Similarities in care may be more marked than differences at alternative and standard services. Staff-patient contact is an important determinant of patient satisfaction, so increasing it should be a priority for all acute in-patient services.

Alternatives to standard acute in-patient care in England: roles and populations served.

BACKGROUND: Key questions regarding residential alternatives to standard acute psychiatric care, such as crisis houses and short-stay in-patient units, concern the role that they fulfil within local acute care systems, and whether they manage people with needs and illnesses of comparable severity to those admitted to standard acute wards. AIMS: To study the extent to which people admitted to residential alternatives and to standard acute services are similar, and the role within local acute care systems of admission to an alternative service. METHOD: Our approach combined quantitative and qualitative methods. Consecutive cohorts of patients in six residential alternatives across England and six standard acute wards in the same areas were identified, and clinical and demographic characteristics, severity of symptoms, impairments and risks compared. Semi-structured interviews with key stakeholders in each local service system were used to explore the role and functioning of each alternative. RESULTS: Being already known to services (OR = 2.6, 95% CI 1.3-5.2), posing a lower risk to others (OR = 0.49, 95% CI 0.31-0.78) and having initiated help-seeking in the current crisis (OR = 2.2, 95% CI 1.2-4.3) were associated with being admitted to an alternative rather than a standard service. Stakeholder interviews suggested that alternatives have a role that is similar but not identical to standard hospital services. They can divert some, but not all, patients from acute admission. CONCLUSIONS: Residential alternatives are integrated into catchment area mental health systems. They serve similar, but not identical, clinical populations to standard acute wards and provide some, but not all, of the functions of these wards.

Thermal resilience of ensilicated lysozyme via calorimetric and in vivo analysis.

Ensilication is a novel method of protein thermal stabilisation using silica. It uses a modified sol-gel process which tailor fits a protective silica shell around the solvent accessible protein surface. This, electrostatically attached, shell has been found to protect the protein against thermal influences and retains its native structure and function after release. Here, we report the calorimetric analysis of an ensilicated model protein, hen egg-white lysozyme (HEWL) under several ensilication conditions. DSC, TGA-DTA-MS, CD, were used to determine unfolding temperatures of native, released and ensilicated lysozyme to verify the thermal resilience of the ensilicated material. Our findings indicate that ensilication protects against thermal fluctuations even at low concentrations of silica used for ensilication. Secondly, the thermal stabilisation is comparable to lyophilisation, and in some cases is even greater than lyophilisation. Additionally, we performed a mouse in vivo study using lysozyme to demonstrate the antigenic retention over long-term storage. The results suggest that protein is confined within the ensilicated material, and thus is unable to unfold and denature but is still functional after long-term storage.

Inhibition of gamma-secretase induces G2/M arrest and triggers apoptosis in breast cancer cells.

Gamma-secretase activity is vital for the transmembrane cleavage of Notch receptors and the subsequent migration of their intracellular domains to the nucleus. Notch overexpression has been associated with breast, colon, cervical and prostate cancers. We tested the effect of three different gamma-secretase inhibitors (GSIs) in breast cancer cells. One inhibitor (GSI1) was lethal to breast cancer cell lines at concentrations of 2 muM and above but had a minimal effect on the non-malignant breast lines. GSI1 was also cytotoxic for a wide variety of cancer cell lines in the NCI60 cell screen. GSI1 treatment resulted in a marked decrease in gamma-secretase activity and downregulation of the Notch signalling pathway with no effects on expression of the gamma-secretase components or ligands. Flow cytometric and western blot analyses indicated that GSI1 induces a G2/M arrest leading to apoptosis, through downregulation of Bcl-2, Bax and Bcl-XL. GSI1 also inhibited proteasome activity. Thus, the gamma-secretase inhibitor GSI1 has a complex mode of action to inhibit breast cancer cell survival and may represent a novel therapy in breast cancer.

Comparison of bone marrow, disseminated tumour cells and blood-circulating tumour cells in breast cancer patients after primary treatment.

The purpose of this study was to determine whether primary breast cancer patients showed evidence of circulating tumour cells (CTCs) during follow-up as an alternative to monitoring disseminated bone marrow tumour cells (DTCs) by immunocytochemistry and reverse transcriptase (RT)-PCR for the detection of micrometastases. We planned to compare CTC and DTC frequency in low-risk and high-risk patients. We identified two cohorts of primary breast cancer patients who were at low (group II, T(1)N(0), n=18) or high (group III, >3 nodes positive (with one exception, a patient with two positive nodes) n=33) risk of relapse who were being followed up after primary treatment. We tested each cohort for CTCs using the CellSearch system on 1-7 occasions and for DTCs by immunocytochemistry and RT-PCR on 1-2 occasions over a period of 2 years. We also examined patients with confirmed metastatic disease (group IV, n=12) and 21 control healthy volunteers for CTCs (group I). All group I samples were negative for CTCs. In contrast, 7 out of 18 (39%) group II primary patients and 23 out of 33 (70%) group III patients were positive for CTCs (P=0.042). If we count only samples with >1 cell as positive: 2 out of 18 (11%) group II patients were positive compared with 10 out of 33 (30%) in group III (P=0.174). In the case of DTCs, 1 out of 13 (8%) group II patients were positive compared with 19 out of 27 (70%) in group III (P<0.001). Only 10 out of 33 (30%) patients in group III showed no evidence of CTCs in all tests over the period of testing, compared with 11 out of 18 (61%) in group II (P=0.033). A significant proportion of poor prognosis primary breast cancer patients (group III) have evidence of CTCs on follow-up. Many also have evidence of DTCs, which are more often found in patients who were lymph node positive. As repeat sampling of peripheral blood is more acceptable to patients, the measurement of CTCs warrants further investigation because it enables blood samples to be taken more frequently, thus possibly enabling clinicians to have prior warning of impending overt metastatic disease.

Juvenile hormone analogs: a possible case of mistaken identity?

Many synthetic compounds that exhibit activity in juvenile hormone assays have limited structural resemblance to natural juvenile hormones. The observed morphogenic action of many of the compounds considered to be biologically analogous to juvenile hormones is probably synergistic rather than intrinsically hormonal.

Radar mapping of mercury: full-disk images and polar anomalies.

A random-code technique has been used at Arecibo to obtain delay-Doppler radar images of the full disk of Mercury. Anomalously bright features were found at the north and south poles. The north polar feature is oblong (4 degrees by 8 degrees ) and offset from the pole. The smaller south polar feature is mostly confined to the floor of the crater Chao Meng-Fu. The polar locations and radar properties of these features indicate that they may be produced by volume scattering in ice. The images also reveal a variety of more subdued reflectivity features ranging in size from hundreds to thousands of kilometers; some of these appear to have an impact origin.

Evidence for highly reflecting materials on the surface and subsurface of vensus.

Radar images at a 12.5-centimeter wavelength made with the Goldstone radar interferometer in 1980 and 1986, together with lunar radar images and recent Venera 15 and 16 data, indicate that material on the surface and subsurface of Venus has a Fresnel reflectivity in excess of 50 percent. Such high reflectivities have been reported on the surface in mountainous regions. Material of high reflectivity may also underlie lower reflectivity surficial materials of the plains regions, where it has been excavated by impact cratering in some areas.
