Psychosocial, psychiatric and work-related risk factors associated with suicide in Ireland: optimised methodological approach of a case-control psychological autopsy study.

BACKGROUND: Suicide has profound effects on families and communities, but is a statistically rare event. Psychological autopsies using a case-control design allow researchers to examine risk factors for suicide, using a variety of sources to detail the psychological and social characteristics of decedents and to compare them to controls. The Suicide Support and Information System Case Control study (SSIS-ACE) aimed to compare psychosocial, psychiatric and work-related risk factors across three groups of subjects: suicide decedents, patients presenting to hospital with a high-risk self-harm episode, and general practice controls. METHODS: The study design includes two inter-related studies; one main case-control study: comparing suicide cases to general practice (GP) controls, and one comparative study: comparing suicide cases to patients presenting with high-risk self-harm. Consecutive cases of suicide and probable suicide are identified through coroners' registration of deaths in the defined region (Cork City and County, Ireland) and are frequency-matched for age group and gender with GP patient controls recruited from the same GP practice as the deceased. Data sources for suicide cases include coroners' records, interviews with health care professionals and proxy informants; data sources for GP controls and for high-risk self-harm controls include interviews with control, with proxy informants and with health care professionals. Interviews are semi-structured and consist of quantitative and qualitative parts. The quantitative parts include a range of validated questionnaires addressing psychiatric, psychosocial and occupational factors. The study adopts several methodological innovations, including accessing multiple data sources for suicide cases and controls simultaneously, recruiting proxy informants to examine consistency across sources. CONCLUSIONS: The study allows for the investigation of consistency across different data sources and contributes to the methodological advancement of psychological autopsy research. The study will also inform clinical and public health practice. The comparison between suicide cases and controls will allow investigation of risk and protective factors for suicide more generally, while the comparison with high-risk self-harm patients will help to identify the factors associated specifically with a fatal outcome to a self-harm episode. A further enhancement is the particular focus on specific work-related risk factors for suicide.

Environmental, health, wellbeing, social and equity effects of urban green space interventions: A meta-narrative evidence synthesis.

BACKGROUND: As populations become increasingly urbanised, the preservation of urban green space (UGS) becomes paramount. UGS is not just dedicated recreational space such as public parks, but other types of informal green space are important, for example, street trees and roof gardens. Despite the potential from cross-sectional evidence, we know little about how to design new, or improve or promote existing UGS for health, wellbeing, social and environmental benefits, or known influencing factors such as physical activity. OBJECTIVES: To perform a meta-narrative review of the evidence regarding the health, wellbeing, social, environmental and equity effects, or known influencing factors of these outcomes, of UGS interventions. DATA SOURCES: Eight electronic databases were searched ((Medline, PsycINFO, Web of Science (Science and Social Science Citation Indices), PADDI (Planning Architecture Design Database Ireland), Zetoc, Scopus, Greenfiles, SIGLE (System for Information on Grey Literature in Europe)), and reference lists of included studies and relevant reviews were hand searched for further relevant studies. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: Eligibility criteria included: (i) evaluation of an UGS intervention; and (ii) health, wellbeing, social or environmental outcome(s), or known influencing factors of these outcomes, measured. Interventions involving any age group were included. Interventions must have involved: (a) physical change to green space in an urban-context including improvements to existing UGS or development of new UGS, or (b) combination of physical change to UGS supplemented by a specific UGS awareness, marketing or promotion programme to encourage use of UGS. STUDY APPRAISAL AND SYNTHESIS METHODS: Following a meta-narrative approach, evidence was synthesised by main intervention approach, including: (i) park-based; (ii) greenways/trails; (iii) urban greening; (iv) large green built projects for environmental purposes. Outcomes such as economic (e.g. cost effectiveness and cost-benefit analyses), adverse effects and unintended consequences were also extracted. Evidence was synthesised following the RAMESES guidelines and publication standards, the PROGRESS-plus tool was used to explore equity impact, and risk of bias/study quality was assessed. The findings from the evidence review were presented at an expert panel representing various disciplines in a workshop and these discussions framed the findings of the review and provide recommendations that are relevant to policy, practice and research. RESULTS: Of the 6997 studies identified, 38 were included. There was strong evidence to support park-based (7/7 studies) and greenway/trail (3/3 studies) interventions employing a dual-approach (i.e. a physical change to the UGS and promotion/marketing programmes) particularly for park use and physical activity; strong evidence for the greening of vacant lots (4/4 studies) for health, wellbeing (e.g. reduction in stress) and social (e.g. reduction in crime, increased perceptions of safety) outcomes; strong evidence for the provision of urban street trees (3/4 studies) and green built interventions for storm water management (6/7 studies) for environmental outcomes (e.g. increased biodiversity, reduction in illegal dumping). Park-based or greenway/trail interventions that did not employ a dual-approach were largely ineffective (7/12 studies showed no significant intervention effect). Overall, the included studies have inherent biases owing to the largely non-randomized study designs employed. There was too little evidence to draw firm conclusions regarding the impact of UGS interventions on a range of equity indicators. LIMITATIONS; CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: UGS has an important role to play in creating a culture of health and wellbeing. Results from this study provide supportive evidence regarding the use of certain UGS interventions for health, social and environmental benefits. These findings should be interpreted in light of the heterogeneous nature of the evidence base, including diverging methods, target populations, settings and outcomes. We could draw little conclusions regarding the equity impact of UGS interventions. However, the true potential of UGS has not been realised as studies have typically under-evaluated UGS interventions by not taking account of the multifunctional nature of UGS. The findings have implications for policymakers, practitioners and researchers. For example, for policymakers the trajectory of evidence is generally towards a positive association between UGS and health, wellbeing, social and environmental outcomes, but any intervention must ensure that negative consequences of gentrification and unequal access are minimised.

A global cline in a colour polymorphism suggests a limited contribution of gene flow towards the recovery of a heavily exploited marine mammal.

Evaluating how populations are connected by migration is important for understanding species resilience because gene flow can facilitate recovery from demographic declines. We therefore investigated the extent to which migration may have contributed to the global recovery of the Antarctic fur seal (Arctocephalus gazella), a circumpolar distributed marine mammal that was brought to the brink of extinction by the sealing industry in the eighteenth and nineteenth centuries. It is widely believed that animals emigrating from South Georgia, where a relict population escaped sealing, contributed to the re-establishment of formerly occupied breeding colonies across the geographical range of the species. To investigate this, we interrogated a genetic polymorphism (S291F) in the melanocortin 1 receptor gene, which is responsible for a cream-coloured phenotype that is relatively abundant at South Georgia and which appears to have recently spread to localities as far afield as Marion Island in the sub-Antarctic Indian Ocean. By sequencing a short region of this gene in 1492 pups from eight breeding colonies, we showed that S291F frequency rapidly declines with increasing geographical distance from South Georgia, consistent with locally restricted gene flow from South Georgia mainly to the South Shetland Islands and Bouvetøya. The S291F allele was not detected farther afield, suggesting that although emigrants from South Georgia may have been locally important, they are unlikely to have played a major role in the recovery of geographically more distant populations.

Monitoring and documentation of side effects from depot antipsychotic medication: an interdisciplinary audit of practice in a regional mental health service.

This audit reviewed current practice within a rural mental health service area on the monitoring and documentation of side effects of antipsychotic depot medication. A sample of 60 case files, care plans and prescriptions were audited, which is 31% of the total number of service users receiving depot injections in the mental health service region (n= 181). The sample audited had a range of diagnoses, including: schizophrenia, schizoaffective disorder, bipolar affective disorder, depression, alcoholic hallucinosis and autism. The audit results revealed that most service users had an annual documented medical review and a documented prescription. However, only five (8%) case notes examined had documentation recorded describing the condition of the injection site, and alternation of the injection site was recorded in only 28 (47%) case notes. No case notes examined had written consent to commence treatment recorded. In 57 (95%) of case notes, no documentation of recorded information on the depot and on side effects was given. The failure to monitor and record some blood tests was partly attributed to a lack of clarity regarding whose responsibility it was. A standardized checklist has been developed as a result of the audit and this will be introduced by all teams across the service.

Knowledge and attitudes of mental health professionals in Ireland to the concept of recovery in mental health: a questionnaire survey.

Recovery is the model of care presently advocated for mental health services internationally. The aim of this study was to examine the knowledge and attitudes of mental health professionals to the concept of recovery in mental health. A descriptive survey approach was adopted, and 153 health care professionals (nurses, doctors, social workers, occupational therapists and psychologists) completed an adapted version of the Recovery Knowledge Inventory. The respondents indicated their positive approach to the adoption of recovery as an approach to care in the delivery of mental health services. However, respondents were less comfortable in encouraging healthy risk taking with service users. This finding is important because therapeutic risk taking and hope are essential aspects in the creation of a care environment that promotes recovery. Respondents were also less familiar with the non-linearity of the recovery process and placed greater emphasis on symptom management and compliance with treatment. Multidisciplinary mental health care teams need to examine their attitudes and approach to a recovery model of care. The challenge for the present and into the future is to strive to equip professionals with the necessary skills in the form of information and training.

Peripheral T-cell lymphoma in a five year old.

We report a case presenting with persistent pyrexia that led to the diagnosis of peripheral T-cell lymphoma, a rare malignancy in childhood. The case illustrates diagnostic conundrums in a patient who is not responding as expected to treatment.

Cardio-pulmonary involvement in juvenile systemic lupus erythematosus.

Cardio-pulmonary manifestations of systemic lupus erythematosus (SLE) are well recognized in adults. We report the occurrence of clinically significant cardio-pulmonary disease in a cohort of predominantly Caucasian children with SLE. All children with SLE attending the Royal Liverpool Children's NHS Trust between 1995 and 2003 were reviewed. Of 29 children with SLE, 27 (93%) were Caucasian. Nine (31%) had cardio-respiratory complications: cardiac only (n = 1); respiratory only (n = 4); both cardiac and respiratory manifestations (n = 4). Median (range) duration of follow-up of affected children: four years (six months to 11 years). Six out of eight (75%) presented with respiratory complications before SLE was diagnosed. Three children had pericardial effusions, one requiring pericardiocentesis for tamponade. One had cardiac conduction defects and another significant pulmonary hypertension. Respiratory complications comprised: interstitial lung disease (n = 4), with two showing evidence of pulmonary fibrosis; pleural effusions (n = 2), pulmonary haemorrhage (n = 1) and lupus pneumonitis (n = 1). Disease course was complicated by CMV infection in one child. Lung biopsy was performed in five cases. Seven were treated with cyclophosphamide with significant improvement in symptoms/lung function. Of this predominantly Caucasian paediatric cohort with SLE, 31% had significant cardio-pulmonary involvement. All children with SLE should have regular monitoring of their cardio-respiratory status.

Nutritional impairment in juvenile idiopathic arthritis.

OBJECTIVE: To investigate the relationship between nutritional impairment, measured by body mass index (BMI), expressed as an age- and sex-standardized standard deviation score (BMI SDS), and disease and patient characteristics in a UK cohort of children with juvenile idiopathic arthritis (JIA). A subgroup with available dietary information were analysed separately. METHODS: Important disease and patient characteristics (age, gender, disease subtype, swollen joint count, painful joint count, restricted joint count, treatment and dietary assessment) were assessed as potential explanatory measures of BMI SDS in a multiple linear regression. RESULTS: Data were collected on 123 consecutive patients. Twenty were nutritionally impaired. In multiple regression analysis excluding the dietary data, disease subtype [persistent oligoarthritis and polyarthritis (rheumatoid factor-negative)], five or more joints with reduced range of movement and being younger were associated with lower BMI SDS (P<0.001). When energy and protein intake were included in the analysis for a subgroup of children, the resulting model retained only disease subtype as a predictor of a low BMI SDS (P = 0.013). CONCLUSIONS: In this unselected population of children with JIA, 16% had evidence of undernutrition. The most commonly affected subtype was oligoarthritis, a previously unreported finding. There is no evidence from this study that this nutritional impairment results from inadequate food intake and it is likely that it is multifactorial in aetiology, disease subtype being the most important factor.

Pamidronate in the treatment of childhood SAPHO syndrome.

BACKGROUND: SAPHO syndrome is increasingly recognized within the paediatric population. Conventional therapeutic approaches have often not been effective. Pamidronate is a second-generation bisphosphonate that affects bone turnover and demonstrates anti-inflammatory properties. In small case series it has given symptomatic relief to adults with this condition. OBJECTIVES: To report the clinical experience with pamidronate in childhood SAPHO syndrome. METHODS: A retrospective observational study of all children with SAPHO syndrome treated with pamidronate between 1996 and 2003 at a tertiary rheumatology centre. The standard dosing regime for pamidronate was 1 mg/kg to a maximum of 30 mg, administered daily for three consecutive days, repeated 3-monthly as required. Response to treatment was determined by clinical observation, patient subjective response and reduction in other treatments RESULTS: Seven girls were treated, with a median (range) age at diagnosis of 11 yr (9-15 yr). All patients demonstrated a beneficial clinical response, with relief of pain, increased activity and improved well-being. Subsequent courses of pamidronate were used in all patients. Other medications including corticosteroids and methotrexate could subsequently be stopped. Transient symptoms were associated with the initial course of pamidronate in some patients. No serious adverse events were reported. CONCLUSIONS: Pamidronate was associated with a marked improvement in function and well-being, and a reduction of pain and use of other medications in all patients, with no significant adverse effects. This study represents preliminary clinical data. A prospective multicentre study is necessary to assess the role and long-term safety of pamidronate in the management of childhood SAPHO syndrome

Intra-articular corticosteroid injections in juvenile idiopathic arthritis.

Therapeutic intervention with intra-articular steroid injections in juvenile idiopathic arthritis (JIA) has evolved from experience with adults with inflammatory joint disease, with the earliest report being published in 1951. The technique has subsequently been introduced into paediatric rheumatology practice, although much of the evidence supporting its use remains anecdotal or based on open, non-controlled studies. This review examines the body of evidence relating to many aspects of treating children with JIA with intra-articular steroids, and is approached from both a medical and a physiotherapy perspective. Where appropriate, important areas for future research are identified and discussed.

Nitrous oxide analgesia during intra-articular injection for juvenile idiopathic arthritis.

AIMS: To evaluate the efficacy and safety of nitrous oxide-oxygen for children with juvenile idiopathic arthritis (JIA) undergoing intra-articular corticosteroid injection. METHODS: A total of 55 consecutive patients with JIA undergoing intra-articular corticosteroid injection, using self administered nitrous oxide-oxygen for analgesia were studied. Patient, nurse, and parent pain scores were compared using a 0-10 cm visual analogue scale (VAS) immediately after the procedure. RESULTS: A total of 70 joints were injected in 55 patients (median age 13.54 years). The median pain score for patient, nurse, and parent was 1 (0-10 cm VAS). The mean rank patient score was 2.12, which was greater than the nurse score (1.97), which was greater than the parent score (1.91). These differences were significant. There were no serious adverse events in any patient. CONCLUSIONS: Nitrous oxide-oxygen provides safe and effective analgesia for intra-articular injection in children. In some cases, nurses and parents underestimated pain related to the procedure compared to the child.

Plasma membrane-cell wall connections: roles in mitosis and cytokinesis revealed by plasmolysis of Tradescantia virginiana leaf epidermal cells.

Tradescantia virginiana leaf epidermal cells were plasmolysed by sequential treatment with 0.8 M and 0.3 M sucrose. Plasmolysis revealed adhesion of the plasma membrane to the cell wall at sites coinciding with cytoskeletal arrays involved in the polarisation of cells undergoing asymmetric divisions--cortical actin patch--and in the establishment and maintenance of the division site--preprophase band of microtubules and filamentous (F) actin. The majority of cells retained adhesions at the actin patch throughout mitosis. However, only approximately 13% of cells formed or retained attachments at the site of the preprophase band. After the breakdown of the nuclear envelope, plasmolysis had a dramatic effect on spindle orientation, cell plate formation, and the plane of cytokinesis. Spindles were rotated at abnormal angles including tilted into the plane of the epidermis. Cell plates formed but were quickly replaced by vacuole-like intercellular compartments containing no Tinopal-stainable cell wall material. This compartment usually opened to the apoplast at one side, and cytokinesis was completed by the furrow extending across the protoplast. This atypical cytokinesis was facilitated by a phragmoplast containing microtubules and F-actin. Progression of the furrow was unaffected by 25 micrograms of cytochalasin B per ml but inhibited by 10 microM oryzalin. Phragmoplasts were contorted and misguided and cytokinesis prolonged, indicating severe disruption to the guidance mechanisms controlling phragmoplast expansion. These results are discussed in terms of cytoskeleton-plasma membrane-cell wall connections that could be important to the localisation of plasma membrane molecules defining the cortical division site and hence providing positional information to the cytokinetic apparatus, and/or for providing an anchor for cytoplasmic F-actin necessary to generate tension on the phragmoplast and facilitate its directed, planar expansion.

Memory for detail in item versus associative recognition.

Some studies have shown that, although repetition increases the familiarity of a stimulus, it does not improve memory for its details. Because memory for associative information is thought to require memory for the details of study presentation, the effects of repetition on associative recognition were examined in the present study. The pattern of results was similar to that found for the recognition of item details: Repetition increased the familiarity of the individual items within each pair to a greater extent than it improved memory for their specific pairings.

Memory for unidentified items: evidence for the use of letter information in familiarity processes.

Participants can give accurate recognition judgments to word fragments that they are unable to complete. In three experiments, the generality of this finding was examined across tasks. Accurate memory judgments in the absence of identification were obtained in item recognition and judgments of presentation frequency but not in associative recognition or list discrimination. The former two tasks are thought to involve the use of familiarity; the latter two are thought to rely on recollection. The present results are consistent with the claim that recognition without identification reflects familiarity processes.
