Testing the effectiveness and acceptability of online supportive supervision for mental health practitioners in humanitarian settings: a study protocol for the caring for carers project. BMC Psychiatry 2023; 23:884. [PMID: 38017407 PMCID: PMC10683137 DOI: 10.1186/s12888-023-05246-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Accepted: 10/01/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND Local humanitarian workers in low and middle-income countries must often contend with potentially morally injurious situations, often with limited resources. This creates barriers to providing sustainable mental health and psychosocial support (MHPSS) to displaced individuals. Clinical supervision is an often neglected part of ensuring high-quality, sustainable care. The Caring for Carers (C4C) project aims to test the effectiveness and acceptability of online group-based supportive supervision on the well-being of MHPSS practitioners, as well as service-user-reported service satisfaction and quality when working with displaced communities in Türkiye, Syria, and Bangladesh. This protocol paper describes the aim, design, and methodology of the C4C project. METHOD A quasi-experimental, mixed-method, community-based participatory research study will be conducted to test the effectiveness of online group-based supportive clinical supervision provided to 50 Syrian and 50 Bangladeshi MHPSS practitioners working with Syrian and Rohingya displaced communities. Monthly data will be collected from the practitioners and their beneficiaries during the active control (six months) and supervision period (16 months over two terms). Outcomes are psychological distress (Kessler-6), burnout (the Copenhagen Burnout Inventory), compassion fatigue, compassion satisfaction, and secondary traumatic stress (Professional Quality of Life Scale), perceived injustice, clinical self-efficacy (Counseling Activity Self-Efficacy Scale), service satisfaction, and quality (Client Satisfaction Questionnaire and an 18-item measure developed in this project). A realist evaluation framework will be used to elucidate the contextual factors, mechanisms, and outcomes of the supervision intervention. DISCUSSION There is a scarcity of evidence on the role of clinical supervision in improving the well-being of MHPSS practitioners and the quality of service they provide to displaced people. By combining qualitative and quantitative data collection, the C4C project will address the long-standing question of the effectiveness and acceptability of clinical supervision in humanitarian settings.

Abstract
Objective Emergency service workers are at risk of experiencing poor mental health due to repeated exposure to potentially traumatic events. Promoting healthy lifestyle factors may help improve health outcomes and quality of life among this population. This study aimed to evaluate the efficacy of a 10-week physical activity (PA) and diet programme delivered via Facebook for sedentary emergency service workers and their support partners on levels of psychological distress. Methods We delivered a 10-week intervention via a private Facebook group facilitated by exercise physiologists, a dietitian and peer-facilitators. Weekly education modules and telehealth calls were delivered, and participants were provided with a PA tracking device (Fitbit accelerometer). A stepped-wedge design was applied to compare levels of psychological distress (K6) during baseline, to intervention by comparing slopes of change. Secondary pre-post outcomes included mental health symptoms, PA, quality of life, social support to exercise, sleep quality and suicidal ideation. Results In total, N=90 participants (n=47 emergency service workers and n=43 support partners) were recruited in 4 cohorts (aged 42.3±11.5 years, 51% male). Levels of psychological distress did not change significantly during the baseline (control) slope and reduced significantly during the first 6 weeks of intervention (intervention slope 1). The slopes were significantly different, b=-0.351, p = 0.003 (i.e. the trajectories of change) and improvements plateaued until follow up. Retention was high (92%) and improvements in mental health symptoms, minutes of PA, sedentary time and quality of life were significant. Conclusions Our intervention delivered via social media is feasible and associated with reduced levels of psychological distress among emergency service workers and support partners.

Abstract
BACKGROUND This research examined the mental health of a cohort of asylum-seeking children, adolescents and their primary caregiver affected by insecure residency while living in the community, compared to refugees and immigrants. METHODS The project investigated the prevalence of psychosocial problems among Iranian and Afghani asylum seeker, refugee and immigrant children and adolescents, and their caregivers who arrived in Australia from 2010. In total, n=196 children and adolescents aged 5-18 years, and their primary caregiver were asked about family visa status, country of origin, level of education, parent symptoms of posttraumatic stress disorder (Harvard Trauma Questionnaire) and child wellbeing (Strengths and Difficulties Questionnaire). An additional n=362 Farsi and Dari speaking children, recruited through the Building a New Life in Australia (BNLA) study, a national comparison sample of families with permanent refugee visas, were included. FINDINGS Asylum seeker children and adolescents displayed significantly more psychosocial problems compared to those with full refugee protection and immigrant background within the current sample and when benchmarked against a national sample of Farsi-Dari speaking refugee children. Higher parental posttraumatic stress disorder symptoms was associated with poorer child and adolescent psychosocial functioning. This effect was more marked in families with insecure residency. INTERPRETATION Insecure visa status is associated with higher rates of children's mental health problems and a stronger association with parental PTSD symptoms compared to children with secure residency. This raises important questions about Australia's restrictive immigration policies. FUNDING This project was supported by an Australian Rotary Health Research Fund / Mental Health of Young Australians Research Grant and by the Australian Research Council (DP160104378).

Abstract
Introduction Mental health and psychosocial support (MHPSS) staff in humanitarian settings have limited access to clinical supervision and are at high risk of experiencing burnout. We previously piloted an online, peer-supervision program for MHPSS professionals working with displaced Rohingya (Bangladesh) and Syrian (Turkey and Northwest Syria) communities. Pilot evaluations demonstrated that online, peer-supervision is feasible, low-cost, and acceptable to MHPSS practitioners in humanitarian settings. Objectives
This project will determine the impact of online supervision on i) the wellbeing and burnout levels of local MHPSS practitioners, and ii) practitioner technical skills to improve beneficiary perceived service satisfaction, acceptability, and appropriateness. Methods MHPSS practitioners in two contexts (Bangladesh and Turkey/Northwest Syria) will participate in 90-minute group-based online supervision, fortnightly for six months. Sessions will be run on zoom and will be co-facilitated by MHPSS practitioners and in-country research assistants. A quasi-experimental multiple-baseline design will enable a quantitative comparison of practitioner and beneficiary outcomes between control periods (12-months) and the intervention. Outcomes to be assessed include the Kessler-6, Harvard Trauma Questionnaire and Copenhagen Burnout Inventory and Client Satisfaction Questionnaire-8. Results A total of 80 MHPSS practitioners will complete 24 monthly online assessments from May 2022. Concurrently, 1920 people receiving MHPSS services will be randomly selected for post-session interviews (24 per practitioner). Conclusions This study will determine the impact of an online, peer-supervision program for MHPSS practitioners in humanitarian settings. Results from the baseline assessments, pilot evaluation, and theory of change model will be presented. Disclosure No significant relationships.

Abstract
ISSUE ADDRESSED The COVID-19 pandemic and associated social distancing regulations have disproportionally impacted the health of older adults. Lifestyle interventions targeting physical activity, diet and fostering social connection may help to alleviate the potential negative health consequences. This study aimed to determine the feasibility and preliminary effectiveness of delivering an online group lifestyle intervention for older adults during the COVID-19 pandemic. METHODS Adults aged 60+, living in Australia were recruited to a single-arm feasibility study of a 6-week program delivered via a private Facebook group between June-August 2020. Facilitators provided motivation and education on weekly topics including goal setting and reducing sedentary behaviour in the form of Facebook posts and group video calls. Primary outcomes included feasibility and acceptability and secondary outcomes included psychological distress, quality of life (AQoL-6D), functioning, loneliness and physical activity (PA) with assessments conducted at baseline, post-intervention and 4-week follow-up. RESULTS N = 11 participants were recruited and n = 10 (91%) completed the post-assessment questionnaires. High acceptability was observed and exploratory analysis from pre-post intervention found evidence of an effect on secondary outcomes. CONCLUSIONS A mental health informed lifestyle program delivered online via Facebook appears feasible and well-accepted among older adults and may help to prevent some of the consequences of inactivity and social isolation associated with the pandemic. SO WHAT?: Online lifestyle interventions appear safe and may provide a scalable, cost-effective strategy for protecting the physical and mental health of older adults during the COVID-19 pandemic.

Abstract
BACKGROUND First responders (eg, police, firefighters, and paramedics) are at high risk of experiencing poor mental health. Physical activity interventions can help reduce symptoms and improve mental health in this group. More research is needed to evaluate accessible, low-cost methods of delivering programs. Social media may be a potential platform for delivering group-based physical activity interventions. OBJECTIVE This study aims to examine the feasibility and acceptability of delivering a mental health-informed physical activity program for first responders and their self-nominated support partners. This study also aims to assess the feasibility of applying a novel multiple time series design and to explore the impact of the intervention on mental health symptoms, sleep quality, quality of life, and physical activity levels. METHODS We co-designed a 10-week web-based physical activity program delivered via a private Facebook group. We provided education and motivation around different topics weekly (eg, goal setting, overcoming barriers to exercise, and reducing sedentary behavior) and provided participants with a Fitbit. A multiple time series design was applied to assess psychological distress levels, with participants acting as their own control before the intervention. RESULTS In total, 24 participants (12 first responders and 12 nominated support partners) were recruited, and 21 (88%) completed the postassessment questionnaires. High acceptability was observed in the qualitative interviews. Exploratory analyses revealed significant reductions in psychological distress during the intervention. Preintervention and postintervention analysis showed significant improvements in quality of life (P=.001; Cohen d=0.60); total depression, anxiety, and stress scores (P=.047; Cohen d=0.35); and minutes of walking (P=.04; Cohen d=0.55). Changes in perceived social support from family (P=.07; Cohen d=0.37), friends (P=.10; Cohen d=0.38), and sleep quality (P=.28; Cohen d=0.19) were not significant. CONCLUSIONS The results provide preliminary support for the use of social media and a multiple time series design to deliver mental health-informed physical activity interventions for first responders and their support partners. Therefore, an adequately powered trial is required.

Abstract
PURPOSE Previous studies have associated developmental stuttering with difficulty learning new motor skills. We investigated non-speech motor sequence learning in children with persistent developmental stuttering (CWS), children who have recovered from developmental stuttering (CRS) and typically developing controls (CON). METHODS Over the course of two days, participants completed the Multi-Finger Sequencing Task, consisting of repeated trials of a10-element sequence, interspersed with trials of random sequences of the same length. We evaluated motor sequence learning using accuracy and response synchrony, a timing measure for evaluation of sequencing timing. We examined error types as well as recognition and recall of the repeated sequences. RESULTS CWS demonstrated lower performance accuracy than CON and CRS on the first day of the finger tapping experiment but improved to the performance level of CON and CRS on the second day. Response synchrony showed no overall difference among CWS, CRS and CON. Learning scores of repeated sequences did not differ from learning scores of random sequences in CWS, CRS and CON. CON and CRS demonstrated an adaptive strategy to response errors, whereas CWS maintained a high percentage of corrected errors for both days. CONCLUSIONS Our study examined non-speech sequence learning across CWS, CRS and CON. Our preliminary findings support the idea that developmental stuttering is not associated with sequence learning per se but rather with general fine motor performance difficulties.

Abstract
OBJECTIVE The aim of this paper was to cross-sectionally examine the association between physical health indicators and PTSD symptomatology. METHOD A cross-sectional study was conducted among inpatients of a service related trauma-focused ward. Physical and mental health indicators including sleep quality, fitness, physical activity, body mass index and PTSD symptomatology were assessed. RESULTS Among 60 inpatients, significant associations were found between sedentary time (r = 0.42; p < .001) and sleep quality (r = 0.40; p < .001) with PTSD symptomatology. The vast majority of inpatients (n = 56; 93%) were found to be either overweight or obese according to body mass index. CONCLUSION Inpatients of a PTSD treatment facility had extremely high rates of obesity, physical inactivity, poor cardiorespiratory fitness and poor sleep quality. Sedentary behaviour is a modifiable risk factor associated with symptoms and physical health.

Abstract
Childhood adversity, such as physical, sexual, and verbal abuse, as well as neglect and family conflict, is a risk factor for schizophrenia. Such adversity can lead to disruptions of cognitive function during development, undermining intellectual capabilities and academic achievement. Schizophrenia is a neurodevelopmental disorder that is associated with cognitive impairments that may become evident during childhood. The Australian Schizophrenia Research Bank database comprises a large community cohort (N = 1169) in which we previously identified 3 distinct cognitive groups among people with schizophrenia: (1) Compromised, current, and estimated premorbid cognitive impairment; (2) Deteriorated, substantial decline from estimated premorbid function; and (3) Preserved, performing in the normal cognitive range without decline. The compromised group displayed the worst functional and symptom outcomes. Here, we extend our previous work by assessing the relationship among these categories of cognitive abilities and reported childhood adversity in 836 patients and healthy controls. Exploratory factor analysis of the Childhood Adversity Questionnaire revealed 3 factors (lack of parental involvement; overt abuse; family breakdown and hardship). People with schizophrenia reported significantly more childhood adversity than healthy controls on all items and factors. People with schizophrenia in the compromised group reported significantly more lack of parental involvement and family breakdown and hardship and lower socioeconomic status than those in the deteriorated group. The cognitive groups were not related to family history of psychosis. These findings identify specific social and family factors that impact cognition, highlighting the important role of these factors in the development of cognitive and functional abilities in schizophrenia.

Abstract
BACKGROUND First responders (police, fire and ambulance officers) are at a significantly increased risk of experiencing poor mental health, including depression and post-traumatic stress disorder. These conditions are associated with high rates of cardiovascular disease, in part due to low levels of physical activity (PA) and high levels of sedentary behaviour. Using a person's social support system may be an effective solution to help increase PA levels to improve mental and physical health outcomes. We will examine the efficacy of a group-based online intervention in increasing PA in first responders and their support partners, iteratively codesigned with advisors with lived experience of mental illness among first responders. METHODS This study will recruit a convenience sample of self-identified sedentary first responders and their self-selected support partners to a 10-week PA programme delivered through a private Facebook group. We will deliver education on predetermined topics related to PA and diet and provide participants with an activity tracker (Fitbit). A stepped-wedged design will be applied to compare multiple baselines to intervention and follow-up phases within subjects. Five cohorts of n=20 will be recruited, with each cohort randomised to a different baseline length. Our primary outcome will be psychological distress (Kessler-6). Secondary outcomes include feasibility, self-report and objective PA data (Simple Physical Activity Questionnaire and Fitbit accelerometry), depression and anxiety (Depression Anxiety and Stress Scale-21 items), post-traumatic stress disorder symptoms (PTSD Checklist for DSM-5), quality of life Assessment of Quality of Life-6 dimensions, sleep quality (The Pittsburgh Sleep Quality Index), suicidal ideation (Suicidal Ideation Attributes Scale) and social support for exercise. The mobile data collection platform MetricWire will be used. ETHICS AND DISSEMINATION Ethical approval was obtained from the University of New South Wales, Deupty Vice-Chancellor Research, Human Research Ethics Committee on 3 June 2019, HC180561. Findings will be published in peer-reviewed journals and disseminated at national conferences. TRIAL REGISTRATION NUMBER ACTRN12619000877189.

Abstract
The knowledge of Syrian psychosocial activists in displaced communities is an invaluable resource for developing an ecological understanding of community needs and attitudes. This may elucidate the structural challenges of displacement to be addressed in psychosocial interventions. During Phase 1 of the study, we employed the community readiness model-a tool to assess community climate, needs, and resources-to determine community capacity-building needs. Eight Syrian key informants were interviewed in Amman, Jordan (December 2013 to January 2014). Community readiness scores were calculated. Thematic analysis explored community identified needs. During Phase 2, a focus group was conducted with 11 local psychosocial workers in Amman (September 2016) employing Phase 1 findings to develop a local capacity-building intervention. For the Phase 1 results, community attitudes toward mental health were reported to be rapidly changing. However, continued stigma, lack of knowledge of service availability, and insufficient number of services were noted as barriers to care. Sense of civic engagement and cultural knowledge of local psychosocial actors were noted as significant strengths. However, lack of access to work rights and technical supervision were identified as contributing to burnout, undermining the sustainability of local, grassroots initiatives. A need for training in clinical interventions, along with ongoing supervision, was identified. For the Phase 2 results, local psychologists elected to receive training in culturally adapted cognitive behavior therapy and operational capacity building. The cultural and contextual knowledge of Syrian community members are invaluable. Unfortunately, failure to provide these professionals with basic work rights and technical support have undermined the sustainability of their endeavors.

[PMID: 30637115 PMCID: PMC6315281 DOI: 10.1017/gmh.2018.30] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2018] [Revised: 08/06/2018] [Accepted: 09/13/2018] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND There is a need for ecological approaches to guide global mental health programmes that can appropriately address the personal, family, social and cultural needs of displaced populations. A transactional ecological model of adaptation to displacement was developed and applied to the case of Syrian refugees living in Jordan. METHODS Syrian and Jordanian psychosocial workers (n = 29) supporting the Syrian refugee community in Jordan were interviewed in three waves (2013-2016). A grounded-theory approach was used to develop a model of key local concepts of distress. Emergent themes were compared with the ecological model, including the five ADAPT pillars identified by Silove (2013). RESULTS The application of the ecological concept of niche construction demonstrated how the adaptive functions of a culturally significant concept of dignity (karama) are moderated by gender and displacement. This transactional concept brought to light the adaptive capacities of many Syrian women while highlighting the ways that stigma may restrict culturally sanctioned opportunities for others, in particular men. By examining responses to potentially traumatic events at the levels of individual, family/peers, society and culture, adaptive responses to environmental change can be included in the formulation of distress. The five ADAPT pillars showed congruence with the psychosocial needs reported in the community. CONCLUSIONS The transactional concepts in this model can help clinicians working with displaced people to consider and formulate a broader range of causal factors than is commonly included in individualistic therapy approaches. Researchers may use this model to develop testable hypotheses.

Abstract
OBJECTIVE Progress toward understanding brain mechanisms in psychosis is hampered by failures to account for within-group heterogeneity that exists across neuropsychological domains. We recently identified distinct cognitive subgroups that might assist in identifying more biologically meaningful subtypes of psychosis. In the present study, we examined whether underlying structural brain abnormalities differentiate these cognitively derived subgroups. METHOD 1.5T T1 weighted structural scans were acquired for 168 healthy controls and 220 patients with schizophrenia/schizoaffective disorder. Based on previous work, 47 patients were categorized as being cognitively compromised (impaired premorbid and current IQ), 100 as cognitively deteriorated (normal premorbid IQ, impaired current IQ), and 73 as putatively cognitively preserved (premorbid and current IQ within 1 SD of controls). Global, subcortical and cortical volume, thickness, and surface area measures were compared among groups. RESULTS Whole cortex, subcortical, and regional volume and thickness reductions were evident in all subgroups compared to controls, with the largest effect sizes in the compromised group. This subgroup also showed abnormalities in regions not seen in the other patient groups, including smaller left superior and middle frontal areas, left anterior and inferior temporal areas and right lateral medial and inferior frontal, occipital lobe and superior temporal areas. CONCLUSIONS This pattern of more prominent brain structural abnormalities in the group with the most marked cognitive impairments-both currently and putatively prior to illness onset, is consistent with the concept of schizophrenia as a progressive neurodevelopmental disorder. In this group, neurodevelopmental and neurodegenerative factors may be important for cognitive function.

Abstract
We measured respiratory flow rates, and expired O2 in 32 (2-34 years, body mass [Mb] range: 73-291 kg) common bottlenose dolphins (Tursiops truncatus) during voluntary breaths on land or in water (between 2014 and 2017). The data were used to measure the resting O2 consumption rate ([Formula: see text], range: 0.76-9.45 ml O2 min-1 kg-1) and tidal volume (VT, range: 2.2-10.4 l) during rest. For adult dolphins, the resting VT, but not [Formula: see text], correlated with body mass (Mb, range: 141-291 kg) with an allometric mass-exponent of 0.41. These data suggest that the mass-specific VT of larger dolphins decreases considerably more than that of terrestrial mammals (mass-exponent: 1.03). The average resting [Formula: see text] was similar to previously published metabolic measurements from the same species. Our data indicate that the resting metabolic rate for a 150 kg dolphin would be 3.9 ml O2 min-1 kg-1, and the metabolic rate for active animals, assuming a multiplier of 3-6, would range from 11.7 to 23.4 ml O2 min-1 kg-1.\absbreak Our measurements provide novel data for resting energy use and respiratory physiology in wild cetaceans, which may have significant value for conservation efforts and for understanding the bioenergetic requirements of this species.

Abstract
Patients with autonomic dysfunction may present with a variety of seemingly unrelated symptoms, both generalised and involving specific systems, including fatigue, difficulty concentrating, orthostatic intolerance, palpitations, constipation or diarrhoea, early satiety, urinary retention or incontinence and erectile dysfunction. Failure to connect the diverse symptoms with a single underlying mechanism may lead to incorrect diagnoses, inappropriate interventions and frustration on the part of both doctors and patients. We describe recent developments in the understanding of the pathophysiology of autonomic dysfunction, including the link between the autonomic and immune systems resulting in the 'inflammatory reflex'. We then provide a rationale to guide the management of patients exhibiting features of autonomic dysfunction, including postural tachycardia syndrome.

Abstract
IMPORTANCE Cognitively distinct subgroups of schizophrenia have been defined based on premorbid and current IQ, but little is known about the neuroanatomical differences among these cognitive subgroups. OBJECTIVES To confirm previous findings related to IQ-based subgroups of patients with schizophrenia in an independent sample and extend those findings to determine the extent to which brain volumetric differences correspond to the IQ-based subgroups. DESIGN, SETTING, AND PARTICIPANTS A total of 183 participants were assessed at the outpatient settings of Neuroscience Research Australia and Lyell McEwin Hospital from September 22, 2009, to August 1, 2012. Patients were classified using cluster analysis on the basis of current and premorbid IQ differences. Regional magnetic resonance imaging (MRI) brain volumes were compared among the IQ-based subgroups using analysis of covariance with intracranial volume and age as covariates. MAIN OUTCOMES AND MEASURES Wechsler Adult Intelligence Scale, third edition, scores; Wechsler Test of Adult Reading scores; Positive and Negative Syndrome Scale scores; and MRI brain volumes. RESULTS Ninety-six outpatients (mean [SD] age, 35.7 [8.4] years; age range, 18-51 years; 59 men) with schizophrenia or schizoaffective disorder and 87 healthy controls (mean [SD] age, 31.9 [8.4] years; age range, 20-50 years; 46 men) were studied. Sixty-two patients and 67 healthy controls underwent structural MRI of the brain. Cluster analyses revealed 25 putatively preserved patients (26%), 33 moderately deteriorated patients (34%), 27 severely deteriorated patients (28%), and 11 compromised patients (12%). Negative symptom scores were significantly worse in the severely deteriorated group relative to the putatively preserved group (F2,82 = 13.8, P < .001, effect size [ES] = 1.40). Patient subgroups analyzed revealed significantly reduced inferior parietal volume relative to controls (F3,113 = 9.7, P < .001, ES = 0.85-1.24). The severely deteriorated group had significantly reduced total hippocampal (mean [SEM], 8309.6 [175.0] vs 9024.0 [145.5]; P = .01), lingual gyrus (mean [SEM], 11 996.0 [531.5] vs 13 838.1 [441.9]; P = .05), and superior temporal sulcus (mean [SEM], 4697.8 [192.0] vs 5446.0 [159.6]; P = .05) gray matter volumes relative to the putatively preserved group (ES = 0.91-1.10). CONCLUSIONS AND RELEVANCE Using an independent sample, we obtained proportions in each IQ-based subgroup that were similar to our previous work. Inferior parietal volume reduction was characteristic of schizophrenia relative to controls, and the severely deteriorated IQ group had widespread volumetric reductions. Classifying cognitive heterogeneity in schizophrenia provides a platform to better characterize the neurobiological underpinnings of the illness and its treatment.

Abstract
BACKGROUND Humanitarian organisations supporting Syrian refugees in Jordan have conducted needs assessments to direct resources appropriately. AIMS To present a model of psychosocial concerns reported by Syrian refugees and a peer review of research practices. METHOD Academic and grey literature databases, the United Nations Syria Regional Response website, key humanitarian organisation websites and Google were searched for needs assessments with Syrian refugees in Jordan between February 2011 and June 2015. Information directly reporting the views of Syrian refugees regarding psychosocial needs was extracted and a qualitative synthesis was conducted. RESULTS Respondents reported that psychological distress was exacerbated by both environmental (financial, housing, employment) and psychosocial outcomes (loss of role and social support, inactivity), which are themselves stressors. Need for improvement in research methodology, participatory engagement and ethical reporting was evident. CONCLUSIONS Participatory engagement strategies might help to address identified psychosocial outcomes. More rigorous qualitative methods are required to ensure accuracy of findings.

Abstract
BACKGROUND Cognitive heterogeneity among people with schizophrenia has been defined on the basis of premorbid and current intelligence quotient (IQ) estimates. In a relatively large, community cohort, we aimed to independently replicate and extend cognitive subtyping work by determining the extent of symptom severity and functional deficits in each group. METHODS A total of 635 healthy controls and 534 patients with a diagnosis of schizophrenia or schizoaffective disorder were recruited through the Australian Schizophrenia Research Bank. Patients were classified into cognitive subgroups on the basis of the Wechsler Test of Adult Reading (a premorbid IQ estimate) and current overall cognitive abilities into preserved, deteriorated, and compromised groups using both clinical and empirical (k-means clustering) methods. Additional cognitive, functional, and symptom outcomes were compared among the resulting groups. RESULTS A total of 157 patients (29%) classified as 'preserved' performed within one s.d. of control means in all cognitive domains. Patients classified as 'deteriorated' (n=239, 44%) performed more than one s.d. below control means in all cognitive domains except estimated premorbid IQ and current visuospatial abilities. A separate 138 patients (26%), classified as 'compromised,' performed more than one s.d. below control means in all cognitive domains and displayed greater impairment than other groups on symptom and functional measures. CONCLUSIONS In the present study, we independently replicated our previous cognitive classifications of people with schizophrenia. In addition, we extended previous work by demonstrating worse functional outcomes and symptom severity in the compromised group.

Adjunctive raloxifene treatment improves attention and memory in men and women with schizophrenia. Mol Psychiatry 2015; 20:685-94.

Abstract
There is increasing clinical and molecular evidence for the role of hormones and specifically estrogen and its receptor in schizophrenia. A selective estrogen receptor modulator, raloxifene, stimulates estrogen-like activity in brain and can improve cognition in older adults. The present study tested the extent to which adjunctive raloxifene treatment improved cognition and reduced symptoms in young to middle-age men and women with schizophrenia. Ninety-eight patients with a diagnosis of schizophrenia or schizoaffective disorder were recruited into a dual-site, thirteen-week, randomized, double-blind, placebo-controlled, crossover trial of adjunctive raloxifene treatment in addition to their usual antipsychotic medications. Symptom severity and cognition in the domains of working memory, attention/processing speed, language and verbal memory were assessed at baseline, 6 and 13 weeks. Analyses of the initial 6-week phase of the study using a parallel groups design (with 39 patients receiving placebo and 40 receiving raloxifene) revealed that participants receiving adjunctive raloxifene treatment showed significant improvement relative to placebo in memory and attention/processing speed. There was no reduction in symptom severity with treatment compared with placebo. There were significant carryover effects, suggesting some cognitive benefits are sustained even after raloxifene withdrawal. Analysis of the 13-week crossover data revealed significant improvement with raloxifene only in attention/processing speed. This is the first study to show that daily, oral adjunctive raloxifene treatment at 120 mg per day has beneficial effects on attention/processing speed and memory for both men and women with schizophrenia. Thus, raloxifene may be useful as an adjunctive treatment for cognitive deficits associated with schizophrenia.

Abstract
BACKGROUND Electrical utility workers wear thick rubber gloves and often work in the cold. OBJECTIVE To document the challenge of working in the cold and the effectiveness of different glove/liner combinations in keeping workers' hands warm. METHODS Ten experienced male electrical utility employees worked in a controlled temperature walk-in chamber at -20 °C for 45 minutes for each of five glove conditions: standard five-finger rubber gloves with cotton liners and gauntlets, mitten style gloves, a prototype wool liner, and two heating options; glove or torso. Dependent measures were maximum grip force, skin temperatures, finger dexterity and sensitivity to touch, ratings of perceived effort and a rating of thermal sensation. RESULTS Participants' hand skin temperatures decreased, they perceived their hands to be much colder, their finger sensitivity decreased and their ratings of perceived exertion increased, however their performance did not degrade over the 45 minute trials. The mitten-style gloves showed a smaller drop in skin temperature for the 3rd and 5th digits (p< 0.05) than the other glove conditions. CONCLUSIONS Mitten style gloves kept workers' hands warmer than the standard five finger glove.

Abstract
OBJECTIVE A six-year study is exploring the most effective ways to disseminate ideas to reduce musculoskeletal disorders (MSDs) in the construction sector. The sector was targeted because MSDs account for 35% of all lost time injuries. This paper reports on the organization of the construction sector, and maps potential pathways of communication, including social networks, to set the stage for future dissemination. PARTICIPANTS The managers, health and safety specialists, union health and safety representatives, and 28 workers from small, medium and large construction companies participated. METHODS Over a three-year period, data were collected from 47 qualitative interviews. Questions were guided by the PARIHS (Promoting Action on Research Implementation in Health Services) knowledge-transfer conceptual framework and adapted for the construction sector. FINDINGS The construction sector is a complex and dynamic sector, with non-linear reporting relationships, and divided and diluted responsibilities. Four networks were identified that can potentially facilitate the dissemination of new knowledge: worksite-project networks; union networks; apprenticeship program networks; and networks established by the Construction Safety Association/Infrastructure Health and Safety Association. CONCLUSIONS Flexible and multi-directional lines of communication must be used in this complex environment. This has implications for the future choice of knowledge transfer strategies.

Abstract
Background Musical performance is a skilled activity performed under intense pressure, thus is often a profound source of anxiety. In other contexts, anxiety and its concomitant symptoms of sympathetic nervous system arousal have been successfully ameliorated with HRV biofeedback (HRV BF), a technique involving slow breathing which augments autonomic and emotional regulatory capacity. Objective: This randomised-controlled study explored the impact of a single 30-minute session of HRV BF on anxiety in response to a highly stressful music performance. Methods A total of 46 trained musicians participated in this study and were randomly allocated to a slow breathing with or without biofeedback or no-treatment control group. A 3 Group×2 Time mixed experimental design was employed to compare the effect of group before and after intervention on performance anxiety (STAI-S) and frequency domain measures of HRV. Results Slow breathing groups (n = 30) showed significantly greater improvements in high frequency (HF) and LF/HF ratio measures of HRV relative to control (n = 15) during 5 minute recordings of performance anticipation following the intervention (effect size: η2 = 0.122 and η2 = 0.116, respectively). The addition of biofeedback to a slow breathing protocol did not produce differential results. While intervention groups did not exhibit an overall reduction in self-reported anxiety, participants with high baseline anxiety who received the intervention (n = 15) displayed greater reductions in self-reported state anxiety relative to those in the control condition (n = 7) (r = 0.379). Conclusions These findings indicate that a single session of slow breathing, regardless of biofeedback, is sufficient for controlling physiological arousal in anticipation of psychosocial stress associated with music performance and that slow breathing is particularly helpful for musicians with high levels of anxiety. Future research is needed to further examine the effects of HRV BF as a low-cost, non-pharmacological treatment for music performance anxiety.

Abstract
Electric utility workers in Canada must frequently work in the cold and must wear thick rubber gloves which can result in rapid fatigue and reduced performance. The purpose of the study was therefore to document the challenge of working in the cold wearing the standard five-finger rubber gloves and covers and compare them to two equipment options, mitten style gloves or a prototype wool liner, and two heating options, glove or torso heating. The dependent measures were grip force, temperature, dexterity (modified Purdue pegboard test and a simulated occupational task), finger sensitivity (Von Frey hair test), perceived effort and thermal sensation. The study population consisted of 10 experienced male utility workers. They worked in a controlled temperature walk-in chamber (-20 degrees Celsius) and performed simulated utility work for 45 minutes with interspersed test batteries. The mitten style glove and woolen liner in a standard glove reduced the effects of working in the cold compared to the standard five-fingered variety with a thin cotton liner. We found that the mitten style glove showed lesser drops in skin temperature for the 3rd and 5th digits than the other conditions (p < 0.05).

Abstract
We report the quantitative genetic analysis of seed oil quality and quantity in six Arabidopsis thaliana recombinant inbred populations, in which the parent accessions were from diverse geographical origins, and were selected on the basis of variation for seed oil content and lipid composition. Although most of the biochemical steps involved in lipid biosynthesis are known and the key genes have been identified, the regulation of the processes that results in the final oil composition and total amount is not understood. By using physically anchored markers it was possible to compare results across populations. A total of 219 quantitative trait loci (QTLs) were identified, of which 81 were significant at P<0.001. Some of these colocalise with QTLs identified previously, but many novel QTLs were also identified. The results highlight the importance of studying traits in multiple populations, which will lead to a better understanding of the contribution that natural variation makes to the genetic architecture of a phenotype.

Abstract
We constructed a linkage map for the population QDH, which was derived from a cross between an oilseed rape cultivar and a resynthesised Brassica napus. The linkage map included ten markers linked to loci orthologous to those encoding fatty acid biosynthesis genes in Arabidopsis thaliana. The QDH population contains a high level of allelic variation, particularly in the C genome. We conducted quantitative trait locus (QTL) analyses, using field data obtained over 3 years, for the fatty acid composition of seed oil. The population segregates for the two major loci controlling erucic acid content, on linkage groups A8 and C3, which quantitatively affect the content of other fatty acids and is a problem generally encountered when crossing "wild" germplasm with cultivated "double low" oilseed rape cultivars. We assessed three methods for QTL analysis, interval mapping, multiple QTL mapping and single marker regression analysis of the subset of lines with low erucic acid. We found the third of these methods to be most appropriate for our main purpose, which was the study of the genetic control of the desaturation of 18-carbon fatty acids. This method enabled us to decouple the effect of the segregation of the erucic acid-controlling loci and identify 34 QTL for fatty acid content of seed oil, 14 in the A genome and 20 in the C genome. The QTL indicate the presence of 13 loci with novel alleles inherited from the progenitors of the resynthesised B. napus that might be useful for modulating the content or extent of desaturation of polyunsaturated fatty acids, only one of which coincides with the anticipated position of a candidate gene, an orthologue of FAD2.
