RESUMO

Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire is a brief 15-item self-report measure of quality of life and life satisfaction originally developed for clinical populations (6 to 17 years old). The current paper examines the initial factor structure proposed by the developers and underlying psychometric properties of the measure in a non-clinical population of teens. A cross-sectional adolescent sample (N = 3222) completed self-report measures as part of mental health promotion program. A confirmatory factor analysis was conducted with construct validity analyses. The original factor structure was replicated with strong internal consistency (Cronbach α = .912). Strong construct validity (e.g. resilience, well-being, depression, and anxiety) was found. Minimal differences were found based on gender, race, and ethnicity. PQ-LES-Q has strong, replicable psychometric properties, which makes it a generally reliable and valid assessment tool to evaluate the quality of life and life satisfaction in adolescents.

RESUMO

OBJECTIVE: To determine if a single baseline adherence assessment (Brief Adherence Rating Scale [BARS]) could identify patients who are likely to respond to long-acting injectable (LAI) antipsychotic treatment. METHOD: The current secondary analysis included a sub-sample of adult outpatients (N = 176) with schizophrenia or schizoaffective disorder who participated in the "A Comparison of Long-Acting Injectable Medications for Schizophrenia (ACLAIMS)" trial and had a baseline BARS assessment and a baseline and month 3 Positive and Negative Syndrome Scale (PANSS) rating. The main outcome was LAI treatment response, defined as a ≥ 20% decrease (baseline to month 3) on the PANSS total score. Receiver Operating Characteristic (ROC) and Area Under the Curve (AUC) analysis was conducted to determine the optimal cutpoint of baseline BARS adherence in discriminating LAI treatment response at month 3. A logistic mixed model estimated the odds of response to LAI treatment at month 3 from the optimal baseline BARS cutpoint. RESULTS: The ROC analysis determined that the single baseline BARS rating (cutoff ≤66%), indicating low adherence, best discriminated patients likely to respond to LAI treatment (AUC = 0.603, SE = 0.046, 95% binomial exact CI = 0.527 to 0.676, p = 0.025), with 38% sensitivity and 85% specificity. The logistic mixed model analysis revealed that patients with ≤66% BARS adherence had 3.464 times the predicted odds (95% CI = 1.604 to 7.480, p = 0.001) of responding to LAI treatment than those who were >66% BARS adherent. CONCLUSION: A single baseline BARS assessment discriminated response to LAI treatment suggesting it is a reasonable tool to identify candidates for LAI antipsychotic treatment.

RESUMO

PURPOSE: Suicide is a leading cause of death among U.S. youth aged 12-18 years. Youth Aware of Mental Health (YAM), a promising, universal, school-based mental health promotion/suicide primary prevention intervention for adolescents, has been evaluated in Europe but not in the U.S. The present study used an uncontrolled, pretest/post-test design to document the potential for YAM to reduce suicidal ideation, attempt, and suicide. A demonstration that help seeking behaviors, mental health literacy, and mental health stigmatizing attitudes improve after the intervention would suggest that the program is promising in the U.S., as well as in Europe, and that further investigation is merited. METHODS: YAM was delivered to 1,878 students in 11 schools as part of regular school curricula. A subset of these students (n = 436) completed surveys before and 3 months postdelivery. Surveys included five questions about help seeking behaviors, a measure of intent to seek help (General Help Seeking Questionnaire), two mental health literacy scales, and two mental illness stigma scales (Reported and Intended Behavior Scale and Personal Stigma and Social Distance Scale). Both McNemar's test and repeated measures linear models were used to determine whether the survey outcomes changed after YAM delivery. RESULTS: Among the 436 adolescents (286 and 150 in Montana and Texas, respectively), significant increases were found pre- to post-intervention in three of five help seeking behaviors, along with improved mental health literacy and decreased mental health-related stigma. Intent to seek help was unchanged. CONCLUSIONS: Several help seeking behavioral factors, mental health knowledge, and stigma improved post-YAM intervention. All three domains are likely protective against suicide. A randomized controlled trial testing the efficacy of YAM in preventing suicidal behaviors is warranted.

RESUMO

Suicide is the second leading cause of death among US adolescents, and rates of suicide among youth have been increasing for the past decade. This study assessed the feasibility and acceptability of the universal, school-based Youth Aware of Mental Health (YAM) program, a promising mental health promotion and suicide primary prevention intervention, in US youth. Using an uncontrolled design, the feasibility and acceptability of delivering and studying YAM were assessed in Montana and Texas schools. Thirteen of 16 (81.3%) schools agreed to support YAM delivery, and five Montana and 6 Texas schools were included in analyses. Facilitators delivered YAM in 78 classes (1,878 students) as regular high school curriculum. Of the total number of students who received YAM, 519 (27.6%) provided parental consent and assent. 436 (84.0%) consented students participated in pre- and post-surveys. Students, parents, and school staff found YAM highly acceptable based on satisfaction surveys. In summary, this study found YAM feasible to implement in US schools. Results also suggest students, parents, and school staff supported school-based programs and were highly satisfied with the YAM program. A randomized controlled trial is warranted to test the efficacy of YAM in promoting mental health and preventing suicidal thoughts and behaviors in US adolescents.

RESUMO

BACKGROUND: Although internet-based cognitive behavior therapy (iCBT) interventions can reduce depression symptoms, large differences in their effectiveness exist. OBJECTIVE: The aim of this study was to evaluate the effectiveness of an iCBT intervention called Thrive, which was designed to enhance engagement when delivered as a fully automated, stand-alone intervention to a rural community population of adults with depression symptoms. METHODS: Using no diagnostic or treatment exclusions, 343 adults with depression symptoms were recruited from communities using an open-access website and randomized 1:1 to the Thrive intervention group or the control group. Using self-reports, participants were evaluated at baseline and 4 and 8 weeks for the primary outcome of depression symptom severity and secondary outcome measures of anxiety symptoms, work and social adjustment, psychological resilience, and suicidal ideation. RESULTS: Over the 8-week follow-up period, the intervention group (n=181) had significantly lower depression symptom severity than the control group (n=162; P<.001), with a moderate treatment effect size (d=0.63). Moderate to near-moderate effect sizes favoring the intervention group were observed for anxiety symptoms (P<.001; d=0.47), work/social functioning (P<.001; d=0.39), and resilience (P<.001; d=0.55). Although not significant, the intervention group was 45% less likely than the control group to experience increased suicidal ideation (odds ratio 0.55). CONCLUSIONS: These findings suggest that the Thrive intervention was effective in reducing depression and anxiety symptom severity and improving functioning and resilience among a mostly rural community population of US adults. The effect sizes associated with Thrive were generally larger than those of other iCBT interventions delivered as a fully automated, stand-alone intervention.

RESUMO

BACKGROUND: The continuum of pro- and anti-inflammatory response elicited by traumatic brain injury (TBI) is suggested to play a key role in the outcome of TBI; however, the underlying mechanisms remain ill -defined. METHODS: Here, we demonstrate that using bone marrow chimeric mice and systemic inhibition of EphA4 receptor shifts the pro-inflammatory milieu to pro-resolving following acute TBI. RESULTS: EphA4 expression is increased in the injured cortex as early as 2 h post-TBI and on CX3CR1gfp-positive cells in the peri-lesion. Systemic inhibition or genetic deletion of EphA4 significantly reduced cortical lesion volume and shifted the inflammatory profile of peripheral-derived immune cells to pro-resolving in the damaged cortex. These findings were consistent with in vitro studies showing EphA4 inhibition or deletion altered the inflammatory state of LPS-stimulated monocyte/macrophages towards anti-inflammatory. Phosphoarray analysis revealed that EphA4 may regulate pro-inflammatory gene expression by suppressing the mTOR, Akt, and NF-κB pathways. Our human metadata analysis further demonstrates increased EPHA4 and pro-inflammatory gene expression, which correlates with reduced AKT concurrent with increased brain injury severity in patients. CONCLUSIONS: Overall, these findings implicate EphA4 as a novel mediator of cortical tissue damage and neuroinflammation following TBI.

RESUMO

OBJECTIVE: To assess expert consensus on barriers and facilitators for long-acting injectable antipsychotic (LAI) use and provide clinical recommendations on issues where clinical evidence is lacking, including identifying appropriate clinical situations for LAI use. METHODS: A 50-question survey comprising 916 response options was distributed to 42 research experts and high prescribers with extensive LAI experience. Respondents rated options on relative appropriateness/importance using a 9-point scale. Consensus was determined using chi-square test of score distributions. Mean (standard deviation) ratings were calculated. Responses to 29 questions (577 options) relating to appropriate patients and clinical scenarios for LAI use are reported. RESULTS: Recommendations aligned with research on risk factors for nonadherence and poor outcomes for patients with schizophrenia/schizoaffective or bipolar disorder. Findings suggested, contrary to general practice patterns, that LAI use may be appropriate earlier in the disease course and in younger patients. Results for bipolar disorder were similar to those for schizophrenia but with less consensus. Numerous facilitators of LAI prescribing were considered important, particularly that LAIs may reduce relapses and improve outcomes. CONCLUSION: Findings support wider use of LAIs in patients with schizophrenia/schizoaffective and bipolar disorders beyond the setting of poor adherence and earlier use in the disease course.

RESUMO

OBJECTIVE: The aim of this study was to provide recommendations on initiating and maintaining long-acting injectable antipsychotics (LAIs) in individuals with schizophrenia/schizoaffective or bipolar disorder. METHODS: A 50-question survey comprising 916 response options was completed by 34 expert researchers and high prescribers with extensive LAI experience, rating relative appropriateness/importance on a 9-point scale. Consensus was determined using chi-square test of score distributions. Results of 21 questions comprising 339 response options regarding LAI initiation, maintenance treatment, adequate trial definition, identifying treatment nonresponse, and switching are reported. RESULTS: Experts agreed that the most important LAI selection factor was patient response/tolerability to previous antipsychotics. An adequate therapeutic LAI trial was defined as the time to steady state ± 1-2 injection cycles. Experts suggested that oral efficacy and tolerability should be established before switching to an LAI, without consensus on the required time, and that the time for oral supplementation and next injection interval should be determined by the time to attainment of therapeutic LAI levels. Most experts agreed that ≥1 adequate LAI trial is needed to identify the lack of efficacy. There was little agreement about strategies for switching between LAIs. CONCLUSION: Expert guidance may aid clinicians in their decisions regarding initiating/maintaining LAIs in individuals with schizophrenia/schizoaffective or bipolar disorder.

RESUMO

BACKGROUND: Studies in the fmr1 KO mouse demonstrate hyper-excitability and increased high-frequency neuronal activity in sensory cortex. These abnormalities may contribute to prominent and distressing sensory hypersensitivities in patients with fragile X syndrome (FXS). The current study investigated functional properties of auditory cortex using a sensory entrainment task in FXS. METHODS: EEG recordings were obtained from 17 adolescents and adults with FXS and 17 age- and sex-matched healthy controls. Participants heard an auditory chirp stimulus generated using a 1000-Hz tone that was amplitude modulated by a sinusoid linearly increasing in frequency from 0-100 Hz over 2 s. RESULTS: Single trial time-frequency analyses revealed decreased gamma band phase-locking to the chirp stimulus in FXS, which was strongly coupled with broadband increases in gamma power. Abnormalities in gamma phase-locking and power were also associated with theta-gamma amplitude-amplitude coupling during the pre-stimulus period and with parent reports of heightened sensory sensitivities and social communication deficits. CONCLUSIONS: This represents the first demonstration of neural entrainment alterations in FXS patients and suggests that fast-spiking interneurons regulating synchronous high-frequency neural activity have reduced functionality. This reduced ability to synchronize high-frequency neural activity was related to the total power of background gamma band activity. These observations extend findings from fmr1 KO models of FXS, characterize a core pathophysiological aspect of FXS, and may provide a translational biomarker strategy for evaluating promising therapeutics.

RESUMO

BACKGROUND: Cortical hyperexcitability due to abnormal fast-spiking inhibitory interneuron function has been documented in fmr1 KO mice, a mouse model of the fragile X syndrome which is the most common single gene cause of autism and intellectual disability. METHODS: We collected resting state dense-array electroencephalography data from 21 fragile X syndrome (FXS) patients and 21 age-matched healthy participants. RESULTS: FXS patients exhibited greater gamma frequency band power, which was correlated with social and sensory processing difficulties. Second, FXS patients showed increased spatial spreading of phase-synchronized high frequency neural activity in the gamma band. Third, we observed increased negative theta-to-gamma but decreased alpha-to-gamma band amplitude coupling, and the level of increased theta power was inversely related to the level of resting gamma power in FXS. CONCLUSIONS: Increased theta band power and coupling from frontal sources may represent a mechanism providing compensatory inhibition of high-frequency gamma band activity, potentially contributing to the widely varying level of neurophysiological and behavioral abnormalities and treatment response seen in full-mutation FXS patients. These findings extend preclinical observations and provide new mechanistic insights into brain alterations and their variability across FXS patients. Electrophysiological measures may provide useful translational biomarkers for advancing drug development and individualizing treatments for neurodevelopmental disorders with associated neuronal hyperexcitability.

RESUMO

OBJECTIVE: This study assessed the relative cost-effectiveness of haloperidol decanoate (HD), a first-generation long-acting injectable (LAI) antipsychotic, and paliperidone palmitate (PP), a second-generation LAI antipsychotic. METHODS: A double-blind, randomized 18-month clinical trial conducted at 22 clinical research sites in the United States compared the cost-effectiveness of HD and PP among 311 adults with schizophrenia or schizoaffective disorder who had been clinically assessed as likely to benefit from an LAI antipsychotic. Patients were randomly assigned to monthly intramuscular injections of HD (25-200 mg) or PP (39-234 mg) for up to 24 months. Quality-adjusted life years (QALYs) were measured by a schizophrenia-specific algorithm based on the Positive and Negative Syndrome Scale and side-effect assessments; total health care costs were assessed from the perspective of the health system. RESULTS: Mixed-model analysis showed that PP was associated with .0297 greater QALYs over 18 months (p=.03) and with $2,100 more in average costs per quarter for inpatient and outpatient services and medication compared with HD (p<.001). Bootstrap analysis with 5,000 replications showed an incremental cost-effectiveness ratio for PP of $508,241 per QALY (95% confidence interval=$122,390-$1,582,711). Net health benefits analysis showed a .98 probability of greater cost-effectiveness for HD compared with PP at an estimated value of $150,000 per QALY and a .50 probability of greater cost-effectiveness at $500,000 per QALY. CONCLUSIONS: HD was more cost-effective than PP, suggesting that PP's slightly greater benefits did not justify its markedly higher costs, which are likely to fall once the medication's patent expires.

RESUMO

OBJECTIVE: The aim of this study was to construct a composite scoring system to predict the probability of placebo response in adolescents with Major Depressive Disorder (MDD). METHOD: Participants of the current study were 151 adolescents (aged 12-17 years) who were randomized to the placebo arm (placebo transdermal patches) of a randomized controlled trial (RCT) comparing the selegiline transdermal patch with placebo (DelBello et al., 2014). The primary outcome of response was defined as a CGI-I score of 1 or 2 (very much or much improved) at week 12 (study-end) or exit. As a first step, a multiple logistic mixed model was used to estimate the odds of placebo response from each predictor in the model, including age, CDRS-R total at baseline (depressive symptom severity), history of recurrent depression (yes vs. no), sex (female vs. male), and race (non-Caucasian vs. Caucasian). On the basis of the initial logistic mixed model analysis, we then constructed an Adolescent Placebo Impact Composite Score (APICS) that became the sole predictor in a re-specified Bayesian logistic regression model to estimate the probability of placebo response. Finally, the AUC for the APICS was tested against a nominal area of 0.50 to evaluate how well the APICS discriminated placebo response status. RESULTS: Among the 151 adolescents, with a mean age of 14.6 years (SD = 1.6) and a mean baseline CDRS-R total of 60.6 (SD = 12.1), 68.2% were females, 50.3% was Caucasian, and 39.7% had a history of recurrent depression. Placebo response rate was 58.3%. Based on the logistic mixed model, the re-specified equation with the highest discriminatory ability to estimate the probability of placebo response was APICS = age + (0.32 × CDRS-R Total at baseline) + (-2.85 × if female) + (-5.50 × if history of recurrent depression) + (-5.85 × if non-Caucasian). The AUC for this model was 0.59 (p = .049). Within a Bayesian decision-theoretic framework, in 95.5% of the time, the 10,000 posterior Monte Carlo samples suggested that as APICS decreased the probability of placebo response increased. The observed APICS and related probability of responding to placebo in this adolescent sample ranged from 14.1 = 74.1% (in placebo responders) to 39.1 = 41.8% (in placebo non-responders). CONCLUSION: The APICS model estimates the probability of placebo response in adolescents with MDD with a modest degree of accuracy (AUC = 0.59) and with a reasonable degree of positive predictive value (74.5%), and is based on five previously identified patient characteristics of placebo response from prior meta-analytic studies (Bridge et al., 2009; Cohen et al., 2010) of randomized placebo-controlled trials of antidepressants in youth with MDD. Calculation of the APICS should be restricted to the range of the adolescent ages (12-17 years) and CDRS-R total scores (17-113); thus, the APICS can assume possible calculated values and related probability of responding to placebo ranging from about 3 (84%) to 53 (25%). The APICS Bayesian logistic model, based on a given aggregate patient profile, has a range of predicted probabilities of placebo response that is fairly wide, albeit truncated, but potentially meaningful for predicting the probability of placebo response among adolescent youth with MDD. The ability of the APICS to objectify the probability of placebo response in adolescents with MDD could be accounted for in the clinical research design of the trial itself and perhaps aid clinicians in treatment strategy for youth who are more likely to experience placebo response.

RESUMO

Anhedonia or inability to experience pleasure not only is a core symptom of major depressive disorder (MDD), but also is identified as an important component of the positive valence system in the NIMH Research Domain Criteria. The Snaith-Hamilton Pleasure Scale (SHAPS) has been developed for the assessment of hedonic experience or positive valence, but has not been well-studied in depressed outpatient populations. The current study examined the reliability and validity of the SHAPS using a sample of adult outpatients with treatment resistant MDD. Data for the current study were obtained from 122 adult outpatients with a diagnosis of MDD and non-response to adequate treatment with an SSRI and who participated in Project TReatment with Exercise Augmentation for Depression (TREAD). A Principal Components Analysis was used to define the dimensionality of the SHAPS. Convergent and discriminant validity were evaluated via correlations of the SHAPS total score with "gold standard" measures of depression severity and quality of life. The SHAPS was found to have high internal consistency (Cronbach's coefficient α = .82). A Principal Components Analysis suggests that the SHAPS is mainly "unidimensional" and limited to hedonic experience among adult outpatients with MDD. Convergent and discriminant validity were assessed by examining the Spearman rank-order correlation coefficient between the SHAPS total score and the HRSD17 (rs = 0.22, p < .03), IDS-C30 (rs = 0.26, p < .01), IDS-SR30 (rs = 0.23, p < .02), QIDS-C16 (rs = 0.22, p < .03), QIDS-SR16 (rs = 0.17, p < .10), QLES-Q (rs = -0.32, p < .002), and the pleasure/enjoyment item (sub-item 21) of the IDS-C (rs = 0.44, p < .0001) and IDS-SR (rs = 0.38, p < .0002). The self-administered SHAPS showed modest sensitivity (76%) and specificity (54%) with the self-administered pleasure/enjoyment single item (sub-item 21) of IDS-SR30. The current study shows that the SHAPS is a reliable and valid instrument to assess hedonic experience or positive valence in adult outpatients with MDD and provides a broader assessment of this important domain.

RESUMO

IMPORTANCE: Long-acting injectable antipsychotics are used to reduce medication nonadherence and relapse in schizophrenia-spectrum disorders. The relative effectiveness of long-acting injectable versions of second-generation and older antipsychotics has not been assessed. OBJECTIVE: To compare the effectiveness of the second-generation long-acting injectable antipsychotic paliperidone palmitate with the older long-acting injectable antipsychotic haloperidol decanoate. DESIGN, SETTING, AND PARTICIPANTS: Multisite, double-blind, randomized clinical trial conducted from March 2011 to July 2013 at 22 US clinical research sites. Randomized patients (n = 311) were adults diagnosed with schizophrenia or schizoaffective disorder who were clinically assessed to be at risk of relapse and likely to benefit from a long-acting injectable antipsychotic. INTERVENTIONS: Intramuscular injections of haloperidol decanoate 25 to 200 mg or paliperidone palmitate 39 to 234 mg every month for as long as 24 months. MAIN OUTCOME MEASURES: Efficacy failure, defined as a psychiatric hospitalization, a need for crisis stabilization, a substantial increase in frequency of outpatient visits, a clinician's decision that oral antipsychotic could not be discontinued within 8 weeks after starting the long-acting injectable antipsychotics, or a clinician's decision to discontinue the assigned long-acting injectable due to inadequate therapeutic benefit. Key secondary outcomes were common adverse effects of antipsychotic medications. RESULTS: There was no statistically significant difference in the rate of efficacy failure for paliperidone palmitate compared with haloperidol decanoate (adjusted hazard ratio, 0.98; 95% CI, 0.65-1.47). The number of participants who experienced efficacy failure was 49 (33.8%) in the paliperidone palmitate group and 47 (32.4%) in the haloperidol decanoate group. On average, participants in the paliperidone palmitate group gained weight and those in the haloperidol decanoate group lost weight; after 6 months, the least-squares mean weight change for those taking paliperidone palmitate was increased by 2.17 kg (95% CI, 1.25-3.09) and was decreased for those taking haloperidol decanoate (-0.96 kg; 95% CI, -1.88 to -0.04). Patients taking paliperidone palmitate had significantly higher maximum mean levels of serum prolactin (men, 34.56 µg/L [95% CI, 29.75-39.37] vs 15.41 µg/L [95% CI, 10.73-20.08]; P <.001, and for women, 75.19 [95% CI, 63.03-87.36] vs 26.84 [95% CI, 13.29-40.40]; P<.001). Patients taking haloperidol decanoate had significantly larger increases in global ratings of akathisia (0.73 [95% CI, 0.59-0.87] vs 0.45 [95% CI, 0.31-0.59]; P=.006). CONCLUSIONS AND RELEVANCE: In adults with schizophrenia or schizoaffective disorder, use of paliperidone palmitate vs haloperidol decanoate did not result in a statistically significant difference in efficacy failure, but was associated with more weight gain and greater increases in serum prolactin, whereas haloperidol decanoate was associated with more akathisia. However, the CIs do not rule out the possibility of a clinically meaningful advantage with paliperidone palmitate. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01136772.

RESUMO

OBJECTIVE: To determine the characteristics of curricula for teaching the content of clinical practice guidelines (CPGs) in psychiatric residency and child and adolescent fellowship programs as well as to determine if and how the learning of CPG content is applied in clinical care settings. METHODS: We conducted a national online survey of directors of general psychiatry residency and child and adolescent fellowship programs in the USA. The survey questionnaire included 13 brief questions about the characteristics used to teach CPGs in the programs, as well as two demographic questions about each program and director. Descriptive statistics were reported for each questionnaire item by program classification (i.e., child and adolescent vs. general psychiatry). RESULTS: The survey response rate was 49.8% (146 out of 293). Just 23% of programs reported having written goals and objectives related to teaching CPGs. The most frequently taught aspect of CPGs was their content (72% of programs). Didactic sessions were the most frequently employed teaching strategy (79% of programs). Regarding the application of CPG learning in treatment care settings, just 16% of programs applied algorithms in care settings, and 15% performed evaluations to determine consistency between CPG recommendations and care delivery. Only 8% of programs utilized audit and feedback to residents about their adherence to CPGs. Faculty time constraints and insufficient interest were the leading barriers (39% and 33% of programs, respectively) to CPG teaching, although 38% reported no barriers. However, child and adolescent programs less commonly identified insufficient interest among faculty as a barrier to teaching CPGs compared to general programs (20% vs. 43%). Moreover, compared to general programs, child and adolescent fellowship programs taught more aspects of CPGs, used more educational activities to teach the content of specific CPGs, and used more methods to evaluate the teaching of CPGs. CONCLUSIONS: Although the majority of programs provided some teaching of CPGs, the rigorousness of the teaching approaches was limited, especially attempts to evaluate the extent and effectiveness of their use in clinical care. Child and adolescent fellowship programs provided more extensive teaching and evaluation related to CPGs.

RESUMO

Adherence to antipsychotic medication was assessed monthly over a 6-month study period using patient-specific electronic monitoring (EM) of medication bottle opening in 23 outpatients with schizophrenia or schizoaffective disorder. Patient-specific EM adherence results were then shared with the seven participating prescribers, who were surveyed concerning the treatment changes, if any, that they would recommend based on the EM adherence results. Prescribers indicated that they would recommend adherence-related treatment plan changes in 61% of patients, all of whom were ≤80% adherent. The strength of this effect was significantly stronger for psychosocial intervention treatment plan change recommendations than for medication treatment plan change recommendations. Of the psychosocial intervention recommendations, an increase in case management intensity was most often recommended. Of the medication treatment plan recommendations, initiation of a long-acting injectable medication and an increase in dosage of current oral antipsychotic medication were each recommended in only one case. Prescriber recommendations of adherence interventions in this study were not necessarily consistent with major guideline recommendations. Findings suggest the need for further study and dissemination of findings regarding evidence-based adherence assessment and interventions.

RESUMO

PURPOSE: This study examined the clinical significance of switching from olanzapine, quetiapine, or risperidone to aripiprazole by examining changes in predicted risk of cardiovascular disease (CVD) according to the Framingham Risk Score (FRS) and metabolic syndrome status. FRS estimates 10-year risk of "hard" coronary heart disease (CHD) outcomes (myocardial infarction and coronary death) while metabolic syndrome is associated with increased risk of CVD, stroke, and diabetes mellitus. METHOD: Changes in FRS and metabolic syndrome status were compared between patients with BMI ≥ 27 and non-HDL-C ≥ 130 mg/dL randomly assigned to stay on stable current treatment (olanzapine, quetiapine, or risperidone) or switch to treatment with aripiprazole with 24 weeks of follow-up. All study participants were enrolled in a behavioral program that promoted healthy diet and exercise. RESULTS: The pre-specified analyses included 89 switchers and 98 stayers who had post-baseline measurements needed to assess changes. Least squares mean estimates of 10-year CHD risk decreased more for the switch (from 7.0% to 5.2%) than the stay group (from 7.4% to 6.4%) (p = 0.0429). The odds ratio for having metabolic syndrome (stay vs. switch) at the last observation was 1.748 (95% CI 0.919, 3.324, p = 0.0885). CONCLUSION: Switching from olanzapine, quetiapine, or risperidone to aripiprazole was associated with larger reductions in predicted 10-year risk of CHD than the behavioral program alone. The advantage of switching on metabolic syndrome was not statistically significant. The benefits of switching must be balanced against its risks, which in this study included more discontinuations of the study treatment but no significant increase in symptoms or hospitalizations.

RESUMO

The objective of this research was to examine the association between sexual dysfunction and subjective quality of life in outpatients with schizophrenia and schizoaffective disorder. The authors evaluated a sample of 238 adult outpatients with diagnoses of schizophrenia or schizoaffective disorder who took quetiapine, olanzapine, or risperidone at study entry with a 1-time rating of the Arizona Sexual Experience Scale and the general life satisfaction scale item of the quality of life index. The authors used multiple linear robust regression and Spearman partial correlation coefficient to examine the relation between subjective quality of life (measured by the general life satisfaction scale item) and sexual functioning (measured by the Arizona sexual experience scale). The authors found a significant negative linear relation between the Arizona Sexual Experience Scale total score and the general life satisfaction scale item for the overall sample (r(s) = -0.16, p = .01), but not separately for men or women. Sexual dysfunction in men and women with schizophrenia and schizoaffective disorder is associated with decreased subjective quality of life, although the magnitude of the effect size was relatively small. Improving clinicians' awareness of the importance of sexual dysfunction in patients may improve tolerability and subsequent treatment outcomes.
