Adolescent Violence in the Home Among Youth Presenting to an Early Psychosis Service: An Exploration of Contributing Factors

Adolescent violence in the home is a growing public health issue and remains under reported and under-researched. The focus of the present research is to investigate factors that may contribute to adolescent violence in the home, among acohort of young people with co-occurring early psychosis. Data relates to 50 young people (16 females, 33 males, 1 nonbinary) aged from 16-25 who were clients at a youth early psychosis service in Melbourne, Australia. Results from a discriminant function analysis revealed the two major contributing factors to whether someone used violence in the home, were whether a young person had a coexisting neurodevelopmental or intellectual disability and whether they used violence outside the home. The findings provide preliminary evidence that engaging in violence outside the home and the presence of a neurodevelopmental or intellectual disability may make it more likely for young people with early psychosis to use violence in the home.

"What makes discovery college different?" a co-produced analysis of student experiences of discovery college

BACKGROUND

Recovery colleges are an education-based approach to supporting mental health recovery that incorporate the voice of both lived and living experience, and experience by training in their design, production, and delivery.

AIMS

To understand students' experiences of attending a youth-focused 'discovery college' course. Specifically, to see whether students were satisfied with the course, whether the learning goals of the courses were met, and what students felt makes discovery college different.

METHODS

A mixed methods design analysed quantitative data on students' ratings of the course and their learning goals. A co-produced thematic analysis, incorporating the voice of lived and living experience, was also conducted on students' responses to the question "what makes discovery college different?"

RESULTS

Overall, students rated their experience with the course very positively, and mostly met the learning goals of courses. The co-produced thematic analysis revealed students valued the incorporation of lived and living experience in courses, the lack of power imbalance between teachers and students, and felt it was a safe space to share and learn.

CONCLUSIONS

Findings support the delivery of the recovery college model within a youth setting, and highlights this as a useful initiative in engaging people from a range of perspectives in education about mental health.

Integrating Substance Misuse Specialists in a Youth Early Psychosis Service: Increasing Mental Health Clinicians' Knowledge and Confidence

Substance misuse and mental health disorders are commonly occurring co-morbidities in young people. This paper reports on a pilot project to embed three specialist Alcohol and Other Drug (AoD) workers to be embedded in a youth early psychosis service to upskill mental health clinicians in managing substance misuse. Evaluation of the project used a mixed methods approach. Quantitative results showed that clinical staff members' knowledge of substance misuse, knowledge of AoD treatments and services, and overall confidence in working with young people with a substance misuse issue improved following implementation of the project. Qualitative results indicated four themes which emerged: defining the role of the AoD workers; support and upskilling of the mental health staff; openness and effective communication between the embedded workers and mental health teams; and barriers to collaboration. The results provide support for the embedding of specialist alcohol and drug workers in youth mental health services.

High-resolution cryo-EM structure of the Shigella virus Sf6 genome delivery tail machine

Sf6 is a bacterial virus that infects the human pathogen Shigella flexneri. Here, we describe the cryo-electron microscopy structure of the Sf6 tail machine before DNA ejection, which we determined at a 2.7-angstrom resolution. We built de novo structures of all tail components and resolved four symmetry-mismatched interfaces. Unexpectedly, we found that the tail exists in two conformations, rotated by ~6° with respect to the capsid. The two tail conformers are identical in structure but differ solely in how the portal and head-to-tail adaptor carboxyl termini bond with the capsid at the fivefold vertex, similar to a diamond held over a five-pronged ring in two nonidentical states. Thus, in the mature Sf6 tail, the portal structure does not morph locally to accommodate the symmetry mismatch but exists in two energetic minima rotated by a discrete angle. We propose that the design principles of the Sf6 tail are conserved across P22-like Podoviridae.

Self-compassion and social anxiety: The mediating effect of emotion regulation strategies and the influence of depressed mood

OBJECTIVES

Self-compassion constitutes a positive way of relating towards the self that enables emotional regulation and reduces emotional distress. This research first explored differences among a sample of persons with social anxiety disorder (SAD) and groups of high socially anxious (HSA) and low socially anxious (LSA) students on self-compassion, emotion regulation, and social anxiety. We then investigated emotional regulation as a mediator of the prediction of social anxiety by self-compassion and the influence of depressed mood on those relationships.

DESIGN

Study 1 compared a SAD group to matched groups of HSA and LSA students. Study 2 utilized the total sample (n = 330 students and n = 33 SAD) to test mediation. Self-compassion and emotion regulation were predictors of social anxiety and depression a covariate.

RESULTS

In Study 1, the SAD group did not differ from the HSA group on most aspects of self-compassion and emotional regulation but was higher on depression. Both were lower on most measures and higher on depression than the LSA group. In Study 2, higher self-compassion predicted lower social interaction anxiety, and emotional regulation strategies mediated this effect, regardless of depression. However, for social performance anxiety, controlling for depression removed mediation. Refraining from uncompassionate responses was directly connected to social anxiety, whereas compassionate responses influenced social anxiety via emotional regulation.

CONCLUSIONS

Results affirm the ameliorative role of self-compassion on social anxiety and emotion regulation strategies as mechanisms of that influence. However, self-compassion's influence was affected by depression and type of social anxiety. Also, refraining from uncompassionate self-responding appears to be of prime importance in predicting social anxiety, whereas compassionate self-responding influences social anxiety via emotion regulation.

Single session family therapy for beginners: what difference does it make to psychiatry registrars to participate in family sessions in front of and behind the screen?

OBJECTIVE

Current competencies required for fellowship of the RANZCP require psychiatry registrars to have experience in working with clients across all age groups, as well as working with families and the client's wider network, however gaining this experience is not always easy for trainees. This paper reports on the experience of participating in Single Session Family Therapy (SSFT) during registrar training as a different modality for learning.

METHOD

An online survey was conducted with fourteen registrars who had participated in SSFT during their child and adolescent rotation. Qualitative and simple quantitative data were collected and analysed.

RESULTS

Participating in SSFT during training was initially daunting, but had a positive effect on trainees, including influencing some towards focussing their future sub-specialisation in the child and youth area. Experience came through learning by doing, and seeing change. Registrars learnt about: understanding the role of the family; teamwork; technical skills; and gained confidence.

CONCLUSIONS

Opportunities for trainees to participate in SSFT enables powerful learning beyond what can be taught in the classroom. Such opportunities may enhance registrars' perceptions of family work, and may positively influence decision about future sub-specialisation.

Self-compassion and emotional regulation as predictors of social anxiety

OBJECTIVES

Self-compassion and emotional regulation have been identified as constructive attitudes towards the self which can reduce emotional distress. This study is the first to examine the role of a self-compassionate attitude towards the self in reducing symptoms of social anxiety. The study also explored the role of emotional regulation strategies of cognitive reappraisal (CR) and expressive suppression (ES) as mechanisms that mediate the impact of self-compassion on social anxiety.

DESIGN

Structural equation modelling (SEM) was conducted on cross-sectional correlational data with MPlus version 6.

METHODS

A sample of 750 undergraduate students (378 men and 372 women) completed an online survey comprised of well validated self-report measures of social anxiety, emotional regulation and self-compassion.

RESULTS

Structural equation modelling showed that self-compassion predicted lower social anxiety directly and indirectly through lower ES. Higher self-compassion also predicted higher CR. Contrary to expectation, CR did not predict lower social anxiety. Exploratory analyses of self-compassion divided into Compassionate Self-responding (CSR) and Refraining from Non-compassionate Responding (RUSR) identified RUSR as a predictor of lower social anxiety directly and indirectly via ES and CR. CSR had no direct effect on social anxiety but did so indirectly via CR.

CONCLUSIONS

The findings provide preliminary evidence that self-compassion can play an important role in alleviating social anxiety and that emotion regulation through ES and CR are important mechanisms of that influence.

PRACTITIONER POINTS

Adopting a more compassionate attitude towards the self can reduce the symptoms of social anxiety Emotional regulation through reducing emotional suppression may be a mechanism whereby higher levels of self-compassion reduce symptoms of social anxiety. Although higher levels of self-compassion predict greater use of emotional regulation through cognitive appraisal, cognitive appraisal does not predict levels of symptoms of social anxiety The capacity to refrain from non-compassionate self-responding may reduce symptoms of social anxiety directly and indirectly through lower levels of emotional suppression and greater cognitive reappraisal (CR). However, compassionate self-responding only influences symptoms of social anxiety through CR.

The relative benefits of nonattachment to self and self-compassion for psychological distress and psychological well-being for those with and without symptoms of depression

OBJECTIVES

Self-compassion represents a way of interacting with the self involving kindness and a balanced approach to negative self-related stimuli that has shown to contribute to reduced depression, anxiety and stress, and increased psychological well-being. Due to the potential barriers towards self-compassion for people with depressive symptoms, the objective of the present study what to investigate whether the emerging construct of 'nonattachment to self', which reflects a flexible and balanced approach to all self-related stimuli, may be more beneficial for positive psychological outcomes than self-compassion, for individuals with depressive symptoms.

METHOD

A sample 388 participants (consisting of 71 men, 317 women) aged from 18 to 77 (M = 35.33, SD = 10.81) completed an online questionnaire measuring levels of self-compassion, nonattachment to self, depressive symptoms, and well-being.

RESULTS

Higher levels of both nonattachment to self and self-compassion were related to reduced psychological distress and increased psychological well-being. However, for people with at least mild depressive symptoms, nonattachment to self was found to be a stronger predictor of reduced psychological distress and increased psychological well-being than self-compassion.

CONCLUSION

In conclusion, the present study suggests both nonattachment to self and self-compassion are associated with better mental health in non-clinical populations. Further, for individuals experiencing at least mild symptoms of depression, self-compassion may be less beneficial than taking a more nonattached stance towards the self. The findings have implications for the way we conceptualize self-focused attention and suggest assisting individuals to let go of their fixated, self-focused attention may be especially beneficial for individuals with depressive symptoms.

PRACTITIONER POINTS

The notion of letting of attachment to the separate static self lies at the core of Buddhist psychological teachings and recent research suggests it can have a positive impact on individuals psychological well-being and ill-being Given the barriers to self-compassion experienced by individuals with depressive symptoms, nonattachment to self may represent a healthy interaction with the self than is met with less resistance than self-compassion. Due to the balanced stance of nonattachment to self towards positive and negative self-related stimuli, it may be prove to be a valuable approach to treating individuals who feel conflict with taking any form of positive or kind stance towards the self.

The Nab experiment: A precision measurement of unpolarized neutron beta decay

Neutron beta decay is one of the most fundamental processes in nuclear physics and provides sensitive means to uncover the details of the weak interaction. Neutron beta decay can evaluate the ratio of axial-vector to vector coupling constants in the standard model, λ = gA/gV, through multiple decay correlations. The Nab experiment will carry out measurements of the electron-neutrino correlation parameter a with a precision of δa/a = 10−3 and the Fierz interference term b to δb = 3 × 10−3 in unpolarized free neutron beta decay. These results, along with a more precise measurement of the neutron lifetime, aim to deliver an independent determination of the ratio λ with a precision of δλ/λ = 0.03% that will allow an evaluation of Vud and sensitively test CKM unitarity, independent of nuclear models. Nab utilizes a novel, long asymmetric spectrometer that guides the decay electron and proton to two large area silicon detectors in order to precisely determine the electron energy and an estimation of the proton momentum from the proton time of flight. The Nab spectrometer is being commissioned at the Fundamental Neutron Physics Beamline at the Spallation Neutron Source at Oak Ridge National Lab. We present an overview of the Nab experiment and recent updates on the spectrometer, analysis, and systematic effects.

Letting Go of Self: The Creation of the Nonattachment to Self Scale

The Buddhist notion of nonattachment relates to an engagement with experience with flexibility and without fixation on achieving specified outcomes. The present study sought to define, create and validate a new measure of nonattachment as it applies to notions of the self. A new construct of “nonattachment to self” (NTS) was developed, defined the absence of fixation on self-related concepts, thoughts and feelings, and a capacity to flexibly interact with these concepts, thoughts and feelings without trying to control them. Two studies were conducted in the development of the new scale. With expert consultation, study 1 (n = 445) established a single factor, internally consistent 7-item scale via exploratory factor analysis. Study 2 (n = 388, n = 338) confirmed the factor structure of the new 7-item scale using confirmatory factor analyses. Study 2 also found the new scale to be internally consistent, with evidence supporting its test-retest reliability, criterion, and construct validity. Nonattachment to self-emerged as a unique way of relating to the self, distinct from general nonattachment, that aligned with higher levels of well-being and adaptive functioning.

First Observation of P-odd γ Asymmetry in Polarized Neutron Capture on Hydrogen

We report the first observation of the parity-violating gamma-ray asymmetry A_{γ}^{np} in neutron-proton capture using polarized cold neutrons incident on a liquid parahydrogen target at the Spallation Neutron Source at Oak Ridge National Laboratory. A_{γ}^{np} isolates the ΔI=1, ^{3}S_{1}→^{3}P_{1} component of the weak nucleon-nucleon interaction, which is dominated by pion exchange and can be directly related to a single coupling constant in either the DDH meson exchange model or pionless effective field theory. We measured A_{γ}^{np}=[-3.0±1.4(stat)±0.2(syst)]×10^{-8}, which implies a DDH weak πNN coupling of h_{π}^{1}=[2.6±1.2(stat)±0.2(syst)]×10^{-7} and a pionless EFT constant of C^{^{3}S_{1}→^{3}P_{1}}/C_{0}=[-7.4±3.5(stat)±0.5(syst)]×10^{-11}  MeV^{-1}. We describe the experiment, data analysis, systematic uncertainties, and implications of the result.

Toward New Therapeutic Mechanisms in Bipolar Disorder: Analog Investigation of Self-Compassion and Nonattachment to Self

There is growing interest in psychological processes that might be targeted in treatments for bipolar disorder (BD). One such process is a vulnerability at the level of self-concept, characterized by presence of, and fluctuations between positive and negative self-concept. The aim of the present study was to advance this literature by investigating the role of two emerging meta-cognitive processes – self-compassion and nonattachment to self – which have potential to therapeutically modulate this unstable self-concept in BD. Using an analog design, it was hypothesized that both variables would mediate the relationship between bipolar tendencies and psychological distress in a general population sample. Participants (N = 372 Australian university students) completed self-report measures of manic and depressive tendencies, self-compassion, nonattachment to self and psychological distress. To investigate the specificity of the two hypothesized mediators, a better-researched psychological variable – rumination – was also included in mediation analyses. Bivariate analyses found tendencies toward mania and depression to be associated with diminished self-compassion and nonattachment to self, while both psychological processes were negatively associated with psychological distress. Mediation analyses showed, as expected, self-compassion and nonattachment to self mediated the relationship between bipolar tendencies and psychological distress after controlling for the effects of rumination. The present findings add incrementally to this literature by demonstrating that two meta-cognitive processes – self-compassion and nonattachment to self – act as mediators, and may be modifiable mechanisms linking bipolar vulnerability to negative mood outcomes. Future research should tackle longstanding conceptual issues in this domain, including the relationship between contents of self-concept (an established focus of BD research) and the person’s meta-cognitive approach to their self-concept (the focus here).

Ultrasound as a Visual Feedback Aid for the Hearing-Impaired

Ultrasound was explored as a visual feedback aid to assist in improving the speech of the deaf and hard of hearing. A mechanical sector real-time scanner produced images of the volunteer's tongue while a speech pathologist provided therapeutic intervention. Pre and postarticulation tests were administered to evaluate change in speech.

Ultrasound as a visual feedback aid may be potentially useful for improving articulation problems for some hearing-impaired speakers. Further research with this population needs to be carried out to explore the practicality of using ultrasound as a visual feedback aid and to gather quantitative data on the long-term effects of learning.

This study has demonstrated that typical real-time sector ultrasound scanners, of the type found in the field today, can be modified to produce useful images of the human tongue during speech production. It is yet unknown what specific type of scanner as well as frequency range is best suited for tongue placement imaging.

Correlates of medication adherence among patients with bipolar disorder: results of the bipolar evaluation of satisfaction and tolerability (BEST) study: a nationwide cross-sectional survey

OBJECTIVE

To identify and describe correlates of medication adherence in a large, national sample of outpatients with bipolar disorder.

METHOD

Data were collected via a self-report, Web-based survey in January and February of 2008 from US patients aged 18-65 years who reported a diagnosis of bipolar disorder and current use of psychotropic medication. Patients with a Composite International Diagnostic Interview-bipolar disorder (CIDI-bipolar disorder) score ≥ 7, indicating a high risk of bipolar disorder, were included in the analyses. Medication adherence was assessed via the Morisky Medication Adherence Scale, with scores ≥ 2 being considered nonadherent. The primary analysis was a multivariate binomial logistic regression with adherence as the dependent variable. Covariates included patient demographics, physical health measures including Medical Outcomes Study 8-item Short-Form Health Survey physical summary score, number of manic and depressive episodes, 24-item Behavior and Symptom Identification Scale (BASIS-24), Liverpool University Neuroleptic Side-Effect Rating Scale (LUNSERS), Satisfaction With Antipsychotic Medication scale (SWAM), and current psychiatric medication use.

RESULTS

Nearly half (49.5%) of the 1,052 bipolar patients in the analysis were classified as being nonadherent. Adherence was positively associated with college degree, higher SWAM total score, and monotherapy treatment. Adherence was negatively associated with female sex, alcohol use, BASIS-24 total score, and LUNSERS total score.

CONCLUSIONS

Nonadherence is common among patients with bipolar disorder. By addressing tolerability issues and treatment satisfaction, which are both significant correlates of adherence, health care providers may be able to improve adherence and, ultimately, treatment outcomes.

Metabolic adverse events in patients with mental illness treated with antipsychotics: a primary care perspective

BACKGROUND

Individuals with mental illness are at a higher risk of medical mortality than the general population, primarily due to an increased risk of cardiovascular disease. There are a number of modifiable metabolic risk factors associated with some atypical antipsychotics that warrant careful monitoring and treatment in both psychiatric and primary care practice if the risk of cardiovascular disease is to be effectively reduced.

DATA SOURCES

Previous guidelines have focused on awareness of metabolic risk factors in psychiatry, yet few articles have appeared in the primary care-focused journals. We present pragmatic guidelines that focus on monitoring metabolic abnormalities in primary care based on established guidelines, including joint recommendations of the American Diabetes Association, the American Psychiatric Association, the American Association of Clinical Endocrinologists, and the North American Association for the Study of Obesity, and the Mount Sinai conference.

DATA SYNTHESIS

All patients receiving atypical antipsychotic agents associated with metabolic adverse events should be routinely monitored for weight gain and abnormalities in blood glucose and lipid levels. Effective communication and collaboration between mental health and primary care services and better access to primary care screening and treatment for individuals with mental health problems are needed.

CONCLUSION

There is a clear need for awareness among primary care physicians, particularly as metabolic effects of atypical antipsychotics such as blood pressure and glucose and lipid levels are possibly best monitored in a primary care setting.

Aripiprazole versus haloperidol treatment in early-stage schizophrenia

We conducted a secondary analysis of a completed study of the differential efficacy and side effects of aripiprazole versus haloperidol in early-stage schizophrenia (ESS), a subpopulation of patients which does not include first episode or chronic patients. A subpopulation of 360 individuals with ESS were identified from a randomized, multi-center, double-blind study of 1294 individuals with schizophrenia at different stages of illness who were randomized to treatment with aripiprazole (ESS = 237) or haloperidol (ESS = 123) for one year. The primary outcome measure was response rate based on a 50% reduction of Positive and Negative Syndrome Scale (PANSS) total scores. Secondary outcomes included several efficacy and safety measures, as well as treatment discontinuation. More individuals in the aripiprazole group (48%) than in the haloperidol group (28%; p < 0.01) completed the study. Response rates were greater in the aripiprazole group (38% [N = 91]) than in the haloperidol group (22% [N = 27]; p < 0.01). Aripiprazole was associated with fewer extrapyramidal side effects. ESS subjects in the haloperidol group were more likely than those in the aripiprazole group to discontinue the study drug due to an adverse event other than worsening illness (29% and 11%, respectively; p < 0.01), and efficacy differences were reduced by interventions to mitigate side effects (decreasing antipsychotic dose with or without adding antiparkinsonian medication). Aripiprazole has a favorable efficacy/safety profile in ESS and appeared to be superior to haloperidol on a number of efficacy and safety outcomes. However, excessive dosing of the antipsychotic medications, in particular haloperidol, may have played an important role in accounting for the differences between aripiprazole and haloperidol in this study.

Cost-sharing effects on adherence and persistence for second-generation antipsychotics in commercially insured patients

PURPOSE

To assess the relationship between patient cost-sharing (e.g., copayments or coinsurance) and adherence and persistence to second-generation (atypical) antipsychotic (SGA) medications.

DESIGN AND METHODOLOGY

A retrospective, observational study of adults aged 18-64 years with schizophrenia or bipolar disorder (n = 7,910) who initiated SGA medications with employer-sponsored insurance in the 2003-2006 MarketScan Commercial Claims and Encounters Database. Adherence was defined as percent of days covered in each calendar quarter. Persistence was defined as days from initiation of SGA to the first 90-day gap in medication on-hand. Generalized Estimating Equations were used to determine the effects of cost-sharing on adherence to SGA medications based on patient-quarter data. A Cox proportional hazards model with patient cost-sharing as a time-varying covariate estimated the effects on persistence with SGA medication.

PRINCIPAL FINDINGS

Higher cost-sharing was associated with a lower likelihood of adherence. When compared to plans with cost-sharing below $10, adherence rates were approximately 27% lower for patients in plans with SGA cost-sharing of $50 and above and about 10% lower for patients in plans with cost-sharing between $30 and $50. In both cases, the reduction in adherence was significant. Higher cost-sharing was also associated with a shorter time to discontinuation (HR: 1.028; 95% CI [1.006-1.051]).

CONCLUSION

High SGA cost-sharing appears to be a financial barrier to SGA medication compliance, especially when cost-sharing levels exceeded $30. Our findings have implications for health plans, employers, and policymakers who have, or are, contemplating establishing cost-sharing tiers for SCA medications for commercially insured patients with serious mental illnesses.

Changes in positive and negative syndrome scale-derived hostility factor in adolescents with schizophrenia treated with aripiprazole: post hoc analysis of randomized clinical trial data

INTRODUCTION

This post hoc analysis evaluated the effects of aripiprazole on Positive and Negative Syndrome Scale (PANSS) Hostility factor scores in adolescents with schizophrenia.

METHODS

In total, 302 adolescents (13-17 years) with schizophrenia were enrolled in a 6-week, multicenter, double-blind, randomized, placebo-controlled trial comparing aripiprazole (10 or 30 mg/day) with placebo. The PANSS was the primary outcome measure. To determine the effect of aripiprazole on hostility, a post hoc analysis of the PANSS Hostility factor and individual items was performed.

RESULTS

Aripiprazole was superior to placebo in reducing PANSS Hostility factor scores in adolescents with schizophrenia. After 6 weeks, aripiprazole 10 mg/day and aripiprazole 30 mg/day showed a statistically significant improvement versus placebo (-3.0, -3.7, versus -2.1; p < 0.05; last observation carried forward [LOCF]) in the PANSS Hostility factor. For aripiprazole 30 mg/day, statistically significant separation from placebo was evident from week 3 through week 6 and at week 6 for aripiprazole 10 mg/day. Individual PANSS Hostility, Uncooperativeness, and Poor Impulse Control Items showed statistically significant improvement with aripiprazole 30 mg/day over placebo at end point.

CONCLUSIONS

This post hoc analysis shows that aripiprazole (10 and 30 mg/day) is an effective treatment for hostility symptoms in adolescents with schizophrenia. Clinical trials information: ClinicalTrials.gov identifier: NCT00102063.

Adherence and outcomes associated with copayment burden in schizophrenia: a cross-sectional survey

OBJECTIVE

Assess the association of schizophrenia patients' perceived copayment burden with medication adherence and outcomes.

METHODS

Patients with schizophrenia (aged 18+) completed self-reported questionnaires. Analyses included those currently using a second-generation antipsychotic (SGA) with no exposure to clozapine or depot formulation antipsychotics. Adherence was assessed using the Morisky Medication Adherence Scale (MMAS). Outcomes included emergency room (ER) use, hospitalization, attempted suicide, missed work due to health, and experiencing severe psychological distress. Logistic regression was used to adjust for demographics, health characteristics, psychotropic medication use, and insurance status.

RESULTS

Of 351 schizophrenia patients, 39% perceived copayment burden. These patients were less than half as likely to have complete adherence [OR = 0.427; 95% CI:0.257, 0.711; p = 0.001] Copayment burden was associated with greater likelihood of ER use, [OR = 2.157; 95% CI:(1.322, 3.520); p = 0.002], hospitalization [OR = 2.512; 95% CI: (1.475, 4.277); p < 0.001], attempted suicide[OR = 2.385; 95% CI: (1.156, 4.920); p = 0.019], severe psychological distress [OR = 1.833; 95% CI:1.092, 3.075; p = 0.022] and greater likelihood of missing work [OR = 7.193; 95% CI: 2.554, 20.256; p < 0.001].

CONCLUSIONS

Copayment burden is associated with poorer medication adherence and outcomes. Formularies that reduce copayment burden for SGAs may positively affect medication adherence and outcomes among schizophrenia patients.

LIMITATIONS

Patient data were self-reported, which may have introduced additional bias in the study measures. Also, the use of a cross-sectional design precludes causal inference and the use of the current sampling methodology (both interview and Internet panel) might impact the ability to generalize the results to the broader population.

Parents with learning disabilities: perceived incidence and needs

Recent literature and government guidance has highlighted the rights of parents with leaming disabilities and role of services in meeting their needs. In the present study, three focus groups were conducted involving 35 members of community health visiting teams in order to identify estimated incidence and needs of parents with learning disabilities and the needs of services in supporting them. The health visiting teams identified clinically significant numbers of parents with learning disabilities and--through qualitative focus group discussion--suggested a significant need for intervention and support for these parents, greater resources and knowledge within health visiting services, and improved interagency co-ordination and communication.

Testing for HIV: concise guidance

HIV is now a treatable medical condition and the majority of those living with the virus remain fit and well on treatment. Despite this a significant number of people in the UK are unaware of their HIV infection and remain at risk to their own health and of passing their virus unwittingly on to others. Late diagnosis is the most important factor associated with HIV-related morbidity and mortality in the U.K. Testing for HIV infection is often not performed due to misconceptions held by healthcare workers even when it is clinically indicated and this contributes to missed or late diagnosis. This article summarises the recommendations from the U.K. national guidelines for HIV testing 2008. The guidelines provide the information needed to enable any clinician to perform an HIV test within good clinical practice and encourage 'normalisation' of HIV testing. The full version is available at www.bhiva.org/cmsl 222621.asp.

Prevalence and predictors of lipid and glucose monitoring in commercially insured patients treated with second-generation antipsychotic agents

OBJECTIVE

The authors sought to quantify plasma lipid and glucose testing rates in patients receiving second-generation antipsychotics before and after guidelines recommending testing were issued in February 2004 by the American Diabetes Association (ADA).

METHOD

In this retrospective cohort analysis using data from a large managed care database (PharMetrics, 2000-2006), patients under age 65 on second-generation antipsychotics were identified and followed from 40 days before to 130 days after the antipsychotic prescription was written. Baseline and 12-week (40 days) lipid and glucose testing rates were determined for pre- and postguideline cohorts. Logistic regression analyses determined predictors of baseline and 12-week lipid and glucose testing while controlling for covariates.

RESULTS

A total of 5,787 preguideline patients and 17,832 postguideline patients were identified. Baseline lipid testing rates were 8.4% for the preguideline cohort and 10.5% for the postguideline cohort, and the 12-week testing rates were 6.8% and 9.0%, respectively. Baseline glucose testing rates were 17.3% for the preguideline cohort and 21.8% for the postguideline cohort, and the 12-week testing rates were 14.1% and 17.9%, respectively. All four comparisons were statistically significant. Baseline and 12-week testing rates for lipids and glucose in children were the lowest of all age groups.

CONCLUSIONS

Despite statistically significant improvements after the ADA guidelines were issued, monitoring for plasma lipids and glucose in this population remains low. Clinicians and administrators responsible for the health of at-risk populations should implement new approaches for effective monitoring of major modifiable risk factors for medical morbidity and mortality in patients taking second-generation antipsychotics.

The moderating impact of ethnicity on metabolic outcomes during treatment with olanzapine and aripiprazole in patients with schizophrenia

OBJECTIVE

Race is strongly associated with risk for metabolic dysfunction, but there is limited prospective data concerning the impact of race on antipsychotic metabolic outcomes among patients with schizophrenia.

METHOD

This study is a post hoc analysis of data from a 26-week, double-blind, randomized trial of aripiprazole (N = 155) and olanzapine (N = 159) conducted from April 2000 through June 2001 in patients aged >or= 18 years with acute schizophrenia according to DSM-IV criteria. The data were analyzed on the basis of racial breakdown: white and black/Hispanic. Between-drug and within-drug outcomes were analyzed separately for each racial cohort across weight, lipid, and glucose parameters.

RESULTS

For white subjects (N = 167), olanzapine significantly worsened all metabolic parameters except high-density lipoprotein (HDL) cholesterol and fasting glucose, and this was significantly different than aripiprazole for every outcome except fasting glucose. In the black/Hispanic cohort (N = 137), olanzapine treatment resulted in adverse metabolic outcomes, and these changes were significantly different from aripiprazole for adiposity, total cholesterol, and non-HDL cholesterol. Aripiprazole decreased the odds of endpoint metabolic syndrome compared with olanzapine for all subjects (OR = 0.33, 95% CI = 0.19 to 0.55), the white cohort (OR = 0.20, 95% CI = 0.10 to 0.41), and black/Hispanic subjects (OR = 0.53, 95% CI = 0.25 to 1.12), but the black/Hispanic result was not statistically significant (p = .096). Within the aripiprazole group, white subjects had significantly lower risk for metabolic syndrome, but there was no significant difference in metabolic syndrome between white and black/Hispanic subjects exposed to olanzapine.

CONCLUSIONS

Race may be an important moderator of metabolic risk during atypical antipsychotic therapy. Olanzapine treatment is associated with greater effects on adiposity and lipids than aripiprazole in both white and black/Hispanic subjects, suggesting that antipsychotic choice and intensive monitoring are important in minimizing metabolic risk, especially in nonwhite patients.

Comparative utility of aripiprazole and haloperidol in schizophrenia: post hoc analysis of two 52-week, randomized, controlled trials

BACKGROUND

Since their introduction, second-generation antipsychotics (SGAs) have become the drugs of choice for the treatment of schizophrenia. However, recent findings have questioned the benefits of SGAs over first-generation antipsychotics (FGAs).

OBJECTIVE

This post hoc analysis sought to compare the utility of the SGA aripiprazole with the FGA haloperidol in patients with early-phase schizophrenia (ES) or chronic schizophrenia (CS).

METHOD

Data were pooled from two identical 52-week, randomized, active comparator trials (31-98-217 and 31-98-304) of aripiprazole 20-30 mg/day versus haloperidol 7-10 mg/day. Patients in the efficacy sample were classified as having ES if they were </=40 years of age with a duration of illness </=5 years. All other patients were classified as having CS. Health-state utilities were derived from the Positive and Negative Syndrome Scale and adverse events, using the last observation carried forward method.

RESULTS

Of 1294 patients in the efficacy sample, 362 met criteria for ES (aripiprazole, n = 239; haloperidol, n = 123) and 932 met criteria for CS (aripiprazole, n = 622; haloperidol, n = 310). Baseline patient characteristics were similar between treatment arms. At week 52, patients treated with aripiprazole in the total and ES populations had significantly greater total utility than those treated with haloperidol, although there were no statistically significant differences in total utility for the CS population at week 52. For the total population, patients treated with aripiprazole had significantly higher quality-adjusted life days (QALDs)/year than haloperidol recipients (+6.48 QALDs/year, p = 0.02). Significantly higher QALDs/year were also seen for aripiprazole-treated patients with ES (+10.65 QALDs/year, p = 0.04) but not for patients with CS (+4.92 QALDs/year, p = 0.14), compared with haloperidol-treated patients.

CONCLUSIONS

Aripiprazole demonstrates greater utility than haloperidol over 52 weeks of treatment. This difference was driven by superiority of aripiprazole over haloperidol in patients with ES, which was not observed in patients with CS.

Predictors of aripiprazole treatment continuation in hospitalized patients

OBJECTIVE

Aripiprazole is a second-generation antipsychotic that is increasingly prescribed in a variety of psychiatric disorders. The goal of this study was to investigate patient and treatment factors associated with aripiprazole treatment continuation on hospital discharge in psychiatric inpatients.

METHOD

This was a retrospective cohort analysis of patients admitted to a psychiatric hospital between January 1, 2003, and June 30, 2006, and treated with aripiprazole. The goal was to determine factors associated with continuation of aripiprazole throughout the hospital stay and on discharge from the hospital. Covariates assessed included patient demographics, prior psychiatric hospitalizations, diagnoses, prior antipsychotic use, and concomitant psychotropic medications. Aripiprazole-specific covariates were starting and maximum dose and dose titration pattern. Diagnoses were identified using ICD-9-CM codes.

RESULTS

There were 1957 aripiprazole-treated patients included in this study, and 1573 (80%) continued aripiprazole treatment at the time of hospital discharge. Median starting doses were lower (5 mg/day) for younger and older patients, and patients with psychotic disorders received higher doses than other patients. Approximately 58% of patients had at least 1 aripiprazole dose titration while hospitalized, and most (73%) of those patients had a dose titration within 3 days of admission. Predictors of treatment continuation in this broad patient population were younger age, a diagnosis of bipolar or major depressive disorder, higher maximum aripiprazole doses, and upward dose titration within 3 days of admission. Patients receiving concomitant anticholinergics or antipsychotics were less likely to continue treatment as were those receiving aripiprazole at the time of hospitalization.

CONCLUSION

In this acute inpatient psychiatric setting, continuation of aripiprazole treatment on discharge was achieved in most patients. Demographic, diagnostic, and treatment factors predicting aripiprazole treatment effectiveness were identified.

Somnolence effects of antipsychotic medications and the risk of unintentional injury

PURPOSE

This study examined the relationship between antipsychotic medications, categorized by published somnolence effects, and unintentional injury (UI).

METHODS

The study population included patients of 18-64 years of age in a healthcare insurance database with claims from 2001 to 2004 and diagnoses of schizophrenia or affective disorder. A nested case-control design was used with cases defined by an E-code claim (a specified external cause of injury) for selected UIs. For cases, the index date referred to the first injury. For controls, the "control index date" was the date of claim if there was only a single medical claim; for patients with > or =2 claims, one was selected at random as the "control index date." Both groups had a prescription for a first-generation antipsychotic (FGA) or second-generation antipsychotic (SGA) overlapping the index date. Potential somnolence effects were defined as: low (referent)--aripiprazole/ziprasidone; medium--risperidone; high--olanzapine/quetiapine: or any single FGA. Logistic regression models were used to estimate odds ratio (OR) and 95% confidence interval (CI) for UI, adjusted for gender, age, concomitant drug, and psychiatric diagnosis.

RESULTS

Among 648 cases and 5214 controls, high-somnolence SGAs were associated with an OR of 1.41 95%CI (1.03-1.93) for risk of UI, while medium-somnolence SGAs, and FGAs had ORs of 1.17 95%CI (0.83-1.64) and 1.17 95%CI (0.79-1.74), respectively. When quetiapine and olanzapine were disaggregated, ORs were 1.61 95%CI (1.15-2.25) and 1.25 95%CI (0.89-1.74), respectively.

CONCLUSIONS

High-somnolence SGAs may lead to UI among patients. When prescribing antipsychotics, clinicians should consider potential somnolence.

Increased adult hippocampal brain-derived neurotrophic factor and normal levels of neurogenesis in maternal separation rats

Repeated maternal separation of rat pups during the early postnatal period may affect brain-derived neurotrophic factor (BDNF) or neurons in brain areas that are compromised by chronic stress. In the present study, a highly significant increase in hippocampal BDNF protein concentration was found in adult rats that as neonates had been subjected to 180 min of daily separation compared with handled rats separated for 15 min daily. BDNF protein was unchanged in the frontal cortex and hypothalamus/paraventricular nucleus. Expression of BDNF mRNA in the CA1, CA3, or dentate gyrus of the hippocampus or in the paraventricular hypothalamic nucleus was not affected by maternal separation. All animals displayed similar behavioral patterns in a forced-swim paradigm, which did not affect BDNF protein concentration in the hippocampus or hypothalamus. Repeated administration of bromodeoxyuridine revealed equal numbers of surviving, newly generated granule cells in the dentate gyrus of adult rats from the 15 min or 180 min groups. The age-dependent decline in neurogenesis from 3 months to 7 months of age did not differ between the groups. Insofar as BDNF can stimulate neurogenesis and repair, we propose that the elevated hippocampal protein concentration found in maternally deprived rats might be a compensatory reaction to separation during the neonatal period, maintaining adult neurogenesis at levels equal to those of the handled rats.

15S-Hydroxyeicosatetraenoic acid activates peroxisome proliferator-activated receptor gamma and inhibits proliferation in PC3 prostate carcinoma cells

15-Lipoxygenase (15-LOX)-2 is expressed in benign prostate secretory cells and benign prostate produces 15S-hydroxyeicosatetraenoic acid (15S-HETE) from exogenous arachidonic acid (AA). In contrast, 15S-LOX-2 and 15S-HETE formation are reduced in prostate carcinoma (Pca). The mechanisms whereby reduced 15-LOX-2 may contribute to Pca development or progression are not known. We investigated the expression of peroxisome proliferator-activated receptor (PPAR) gamma in benign and malignant prostate tissues and the ability of 15S-HETE to activate PPARgamma-dependent transcription and modulate proliferation of the Pca cell line PC3. In contrast to benign prostate and similar to most Pca tissues, 15-LOX-2 mRNA was not detected in PC3 cells, and they did not produce detectable 15-HETE from [14C]AA. By reverse transcription-PCR, PPARgamma mRNA was present in 18 of 18 benign and 9 of 9 tumor specimens. The PPARgamma ligand BRL 49653 and 15S-HETE caused a dose-dependent inhibition of PC3 proliferation in a 14-day soft agar colony-forming assay (IC50 of 3 and 30 microM, respectively). 15S-HETE (10 microM) caused greater inhibition than 10 microM 15R-HETE. At 3 days, BRL 49653 and 15S-HETE caused a slight increase in cells in G0-G1 and a corresponding decrease in cells in S phase. In PC3 cells transiently transfected with a luciferase reporter linked to a PPAR response element, 1 microM BRL 49653 and 10 microM 15S-HETE caused approximately threefold and greater than twofold induction of PPAR-dependent transcription, respectively. By quantitative real-time reverse transcription-PCR and Northern analysis, 3-day treatment with BRL 49653 and 15S-HETE caused a reduction of PPARgamma expression but a marked up-regulation of the PPAR response element containing adipocyte type fatty acid binding protein. These results support the hypothesis that 15-LOX-2-derived 15S-HETE may constitute an endogenous ligand for PPARgamma in the prostate and that loss of this pathway by reduced expression of 15-LOX-2 may contribute to increased proliferation and reduced differentiation in prostate carcinoma.

Families with autosomal dominant brachydactyly type E, short stature, and severe hypertension

BACKGROUND

Rare, monogenic forms of hypertension may give insight into novel mechanisms relevant to essential hypertension. Autosomal dominant hypertension with brachydactyly has been documented in a single Turkish kindred; the gene was mapped to chromosome 12p.

OBJECTIVE

To describe the molecular genetics of additional families with autosomal dominant hypertension and brachydactyly.

DESIGN

Case series.

SETTING

Tertiary care medical centers.

PATIENTS

An 11-member Canadian family and a 7-member U.S. family, neither of Turkish background, with autosomal dominant hypertension and type E brachydactyly.

MEASUREMENTS

Clinical evaluation, genotyping, and haplotype analyses.

RESULTS

The mode of inheritance, the type E brachydactyly, and the propensity for stroke were consistent with autosomal dominant hypertension with brachydactyly. The same markers on chromosome 12p cosegregated with the phenotype in the families. A haplotype analysis strongly supported the conclusion that these families have a molecular defect in the same gene.

CONCLUSIONS

The syndrome of autosomal dominant hypertension and brachydactyly is not confined to patients of Turkish origin. All persons with brachydactyly should have their blood pressure measured, and the syndrome should be considered if hypertension is found.

Musculoskeletal injuries in adolescents

This article reviews the anatomy of the physis and the most common classification of injuries or fractures through the physis. The common apophyseal injuries of Osgood-Schlatter, Severs disease and iliac apophysitis, are reviewed in addition to a review of the most common osteochondritides, including Panner's disease and Osteochondritis Dessicans of the femur and talus. An understanding of these is key to diagnosis and treatment of adolescent musculoskeletal injuries. This article also reviews slipped capital femoral epiphysis, little leaguer's elbow, anterior cruciate and collateral ligament injuries, patella problems, ankle sprains and several common fractures in children.

Avoiding state intervention in not-for-profit/for-profit affiliations

States attorneys general recently have intervened in transactions involving not-for-profit organizations that wish to convert to or transfer assets to for-profit status. These interventions are significant for two reasons: first, they reflect a tendency amount state attorneys general to involve states in the governance of not-for-profit healthcare organizations, and second, they demonstrate that attorneys general are paying renewed attention to the legal obligation of such organizations to provide a community health benefit, which imposes a charitable trust on not-for-profit healthcare organizations and the fiduciary duties of care and loyalty to that charitable trust on the organizations' officers and directors. To avoid state intervention in such transactions, officers and directors of not-for-profit organizations need to understand the circumstances under which attorneys general justify such intervention, which include the undervaluation of the organization's charitable assets; lack of a private letter ruling from the IRS; failure to adequately consider alternatives to the transaction; conflicts with the best interest of the organization; and inadequate responses to the attorney general's requests for information.

Effects of cue validity upon performance in the attention cueing paradigm

Two experiments were run wherein normal subjects made choice reactions to targets preceded by location cues. Systematic manipulation of the predictive validity of the cue produced consistent advantages for subjects in the low as opposed to the high predictive validity condition. Performance advantages were observed in both response time and accuracy measures. The results are discussed with respect to models of visual orienting and controlled versus automatic processing.

IRS eases rules for physician representation on governing boards

In September 1996, the IRS eased its policy prohibiting extensive physician representation on governing boards of tax-exempt integrated delivery systems (IDSs). The IRS now allows increased physician participation on governing boards if the organizations institute conflict-of-interest safeguards that prohibit physicians from obtaining private inurements. A section of the Internal Revenue Code, enacted in 1996 by the Taxpayer Bill of Rights 2, strengthens the IRS's enforcement policy by providing targeted sanctions against individual violators of the private inurement rule rather than penalizing entire IDSs and the communities they serve by revoking their tax-exempt status.

Stress and performance: an application of Gray's three-factor arousal theory to basketball free-throw shooting

The suitability of Gray's (1975) three-factor arousal theory as a model of human performance under stress was investigated in a study of basketball free-throw shooting. Free-throw attempts, made by members of an NCAA Division I men's varsity team, were videotaped during one full season. On the basis of Gray's theory, we predicted that increased stress (assumed to be present in games as opposed to practices) would be associated with longer pre-shot preparations and a greater incidence of overthrow shots. The prediction was confirmed by the results. Moreover, we found that free-throws were more frequently overthrown when attempted during crucial rather than non-crucial game situations. Further tests of the utility of Gray's theory are suggested.

Resistance training-induced increases in muscle mass and performance in ponies

The purpose of this study was to determine whether 8 wk of progressive resistance exercise training would produce increases in strength and changes in foreleg muscle characteristics indicative of hypertrophy in ponies. Two mature 3- to 6-yr-old, male ponies (188 +/- 16 kg) were taught to carry sheets of lead over their saddle region (wither) while walking on a level treadmill at 1.9 m.s-1. This initial familiarization period was followed by 8 wk of training (3 d per wk), in which the ponies performed a series of progressive sets of weight carrying to fatigue. Each workout started with a 2-min walk at 1.9 m.s-1 followed by sets of weight carrying. The ponies carried 44.5 kg for the first set with increases of 22.3 kg per set until fatigue. Weights were applied and then removed for 60-90 s between sets using a chain hoist and sling apparatus. Measurements of forelimb girth, body weight, and total weight carried were recorded at each workout session. Ultrasound measurement of the diameters of the superdigital flexor muscles and muscle biopsies were performed before and after the 8-wk training period. Eight weeks of resistance training resulted in significant increases in peak weight carried (260%, P < 0.05) and total weight carried (1525%, P < 0.05) during each workout. Forelimb girth increased 12 +/- 1% (P < 0.05) with a corresponding 19 +/- 3% (P < 0.05) increase in muscle cross-sectional diameter. There were no changes (P > 0.05) in Type I muscle fiber area; however, there was a nonsignificant 26% increase in Type IIA+IIB fiber area. These data suggest that 8 wk of progressive resistance exercise training increase strength and cause changes in muscle size and characteristics consistent with hypertrophy.
