African-American patients with cancer Talking About Clinical Trials (TACT) with oncologists during consultations: evaluating the efficacy of tailored health messages in a randomised controlled trial-the TACT study protocol.

INTRODUCTION: Low rates of accrual of African-American (AA) patients with cancer to therapeutic clinical trials (CTs) represent a serious and modifiable racial disparity in healthcare that impedes the development of promising cancer therapies. Suboptimal physician-patient consultation communication is a barrier to the accrual of patients with cancer of any race, but communication difficulties are compounded with AA patients. Providing tailored health messages (THM) to AA patients and their physician about CTs has the potential to improve communication, lower barriers to accrual and ameliorate health disparities. OBJECTIVE: (1) Demonstrate the efficacy of THM to increase patient activation as measured by direct observation. (2) Demonstrate the efficacy of THM to improve patient outcomes associated with barriers to AA participation. (3) Explore associations among preconsultation levels of: (A) trust in medical researchers, (B) knowledge and attitudes towards CTs, (C) patient-family member congruence in decision-making, and (D) involvement/information preferences, and group assignment. METHODS AND ANALYSIS: First, using established methods, we will develop THM materials. Second, the efficacy of the intervention is determined in a 2 by 2 factorial randomised controlled trial to test the effectiveness of (1) providing 357 AA patients with cancer with THM with 2 different 'depths' of tailoring and (2) either providing feedback to oncologists about the patients' trial THM or not. The primary analysis compares patient engaged communication in 4 groups preconsultation and postconsultation. ETHICS AND DISSEMINATION: This study was approved by the Virginia Commonwealth University Institutional Review Board. To facilitate use of the THM intervention in diverse settings, we will convene 'user groups' at 3 major US cancer centres. To facilitate dissemination, we will post all materials and the implementation guide in publicly available locations. TRIAL REGISTRATION NUMBER: NCT02356549.

SAMe and sexual functioning.

BACKGROUND: Sexual dysfunction is a known side effect of antidepressant treatment (ADT), affecting up to 58-73% of those who receive ADT, potentially affecting antidepressant adherence. Consequently, it is vital to develop novel treatments that target antidepressant-induced sexual dysfunction. METHODS: We examined whether adjunctive S-adenosyl-l-methionine (SAMe) is associated with greater improvement in sexual functioning than adjunctive placebo by measuring changes in sexual functioning using the Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ) during a 6-week, single-center, randomized, double-blind trial of SAMe augmentation for SSRI/SNRI- nonresponders. RESULTS: Controlling for the degree of arousal dysfunction at baseline as well as the degree of change in HDRS-17 scale scores during the course of the study, men treated with adjunctive SAMe demonstrated significantly lower arousal dysfunction at endpoint than those treated with adjunctive placebo. In addition, controlling for the degree of erectile dysfunction at baseline as well as the degree of change in HDRS-17 scale scores, men treated with adjunctive SAMe demonstrated significantly lower erectile dysfunction at endpoint than those treated with adjunctive placebo. CONCLUSIONS: In the present study, we have observed that adjunctive SAMe can have positive benefit on male arousal and erectile dysfunction, independent of improvement in depressive symptoms. These findings are preliminary, and warrant replication.

Effects of S-adenosylmethionine augmentation of serotonin-reuptake inhibitor antidepressants on cognitive symptoms of major depressive disorder.

UNLABELLED: Major depressive disorder (MDD) is often accompanied by significant cognitive impairment, and there are limited interventions specific to this particular symptom. S-adenosylmethionine (SAMe), a naturally occurring molecule which serves as a major methyl-donor in human cellular metabolism, is required for the synthesis and maintenance of several neurotransmitters that have been implicated in the pathophysiology and treatment of cognitive dysfunction in MDD. OBJECTIVES: This study is a secondary analysis of a clinical trial involving the use of adjunctive SAMe for MDD. METHODS: Forty-six serotonin-reuptake inhibitor (SRI) non-responders with MDD enrolled in a 6-week, double-blind, randomized trial of adjunctive oral SAMe were administered the self-rated cognitive and physical symptoms questionnaire (CPFQ), a validated measure of cognitive as well as physical symptoms of MDD, before and after treatment. RESULTS: There was a greater improvement in the ability to recall information (P=0.04) and a trend towards statistical significance for greater improvement in word-finding (P=0.09) for patients who received adjunctive SAMe than placebo. None of the remaining five items reached statistical significance. CONCLUSIONS: These preliminary data suggest that SAMe can improve memory-related cognitive symptoms in depressed patients, and warrant replication.

Irritability is associated with anxiety and greater severity, but not bipolar spectrum features, in major depressive disorder.

OBJECTIVE: Irritability is common during major depressive episodes, but its clinical significance and overlap with symptoms of anxiety or bipolar disorder remains unclear. We examined clinical correlates of irritability in a confirmatory cohort of Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study participants with major depressive disorder (MDD). METHOD: Logistic regression was used to identify features associated with presence of irritability on the clinician-rated Inventory of Depressive Symptomatology. RESULTS: Of 2307 study participants, 1067(46%) reported irritability at least half the time during the preceding week; they were more likely to be female, to be younger, to experience greater depression severity and anxiety, and to report poorer quality of life, prior suicide attempts and suicidal ideation. Bipolar spectrum features were not more common among those with irritability. CONCLUSION: Irritable depression is not a distinct subtype of MDD, but irritability is associated with greater overall severity, anxiety comorbidity and suicidality.

Pretreatment frontal EEG and changes in suicidal ideation during SSRI treatment in major depressive disorder.

OBJECTIVE: We investigated frontal quantitative EEG (QEEG) as predictor of changes in suicidal ideation (SI) during SSRI treatment in major depressive disorder (MDD). METHOD: Eighty-two subjects meeting DSM-IV criteria for MDD entered an 8-week, prospective, open-label treatment with flexible dose SSRIs and completed at least 4 weeks of treatment. We assessed MDD severity with the 17-item Hamilton Depression Rating Scale (HAM-D-17); change in SI was measured with HAM-D item no. 3. We recorded four-channel EEGs (F7-Fpz, F8-Fpz, A1-Fpz, A2-Fpz) before treatment. RESULTS: During the first 4 weeks of treatment 9 (11%) subjects experienced worsening SI. Left-right asymmetry of combined theta + alpha power correlated significantly with change in SI from baseline, even when adjusting for changes in depression severity (HAM-D-17) and for the SSRI utilized. CONCLUSION: Frontal QEEG parameters before treatment may predict worsening SI during SSRI treatment in MDD.

Preadult onset vs. adult onset of major depressive disorder: a replication study.

OBJECTIVE: In the first 1500 participants with major depressive disorder (MDD) that entered the sequenced treatment alternatives to relieve depression (STAR*D) study, those with preadult onset MDD were more likely to be women and to have a more chronic, severe and disabling form of depression than those with adult onset MDD. This study seeks to replicate these findings. METHOD: The second wave of STAR*D enrollees included 2541 out-patients with MDD, divided into preadult (before age 18) and adult (age 18 or later) onset groups. RESULTS: Participants with a preadult onset of MDD (38%) were younger, ill for longer and more likely to be women than those with adult onset MDD (62%). After adjusting for age, duration of illness and gender, participants with preadult onset MDD also had higher rates of family history of depression, more past suicide attempts, and lower rates of obsessive compulsive and panic disorder. CONCLUSION: Preadult onset MDD may be associated with a more familial form of depression with more suicidality than adult onset MDD.

Factors associated with chronic depressive episodes: a preliminary report from the STAR-D project.

OBJECTIVE: To identify baseline sociodemographic and clinical factors associated with a current chronic major depressive episode (MDE). METHOD: Outpatients with major depressive disorder enrolled in 41 US primary or psychiatric care sites were divided into two groups based on self-report of current episode length (<24 or > or =24 months). Logistic regression models were used to identify factors associated with chronicity of current depressive episode. RESULTS: About 21.2% of 1380 subjects were in current, chronic MDEs. Older age, less education, lower income, no private insurance, unemployment, greater general medical illness burden, lower physical quality of life, concurrent generalized anxiety disorder, fewer prior episodes, and history of prior suicide attempts were all associated with chronic episodes. Blacks, Hispanics, and patients receiving care in primary as opposed to psychiatric care settings exhibited greater chronicity. CONCLUSION: Chronic depressive episodes are common and are associated with greater illness burden, comorbidity, socioeconomic disadvantage, and racial/ethnic minority status.

The potential relationship between levels of perceived stress and subtypes of major depressive disorder (MDD).

OBJECTIVE: We wanted to explore whether major depressive disorder (MDD) subtypes (melancholic depression, atypical depression, double depression, and MDD with anger attacks) were related to levels of perceived stress, as measured by the Perceived Stress Scale (PSS). METHOD: Our sample [n = 298; female = 163 (55%); mean age 40.1 +/- 10.5 years] consisted of out-patients with MDD. The Structured Clinical Interview for DSM-III-R, the 17-item Hamilton Rating Scale for Depression, the Anger Attack Questionnaire, and the PSS were administered prior to initiating treatment. RESULTS: Depressed women had significantly higher levels of perceived stress (P = 0.02) than depressed men. Greater severity of depression at baseline was significantly related to higher levels of perceived stress (P < 0.0001). After adjusting for age, gender, and severity of depression at baseline, higher levels of perceived stress were significantly related to the presence of anger attacks (P < 0.0001; t = -4.103) as well as to atypical depression (P = 0.0013; t = 3.26). CONCLUSION: Out-patients with MDD who are more irritable and/or present with atypical features have higher levels of perceived stress, indicating a potential reactive component to their depression.

Continuation cognitive-behavioural therapy maintains attributional style improvement in depressed patients responding acutely to fluoxetine.

BACKGROUND: Little is known about how continuation and maintenance cognitive-behavioural therapy (CBT) influences important psychological constructs that may be associated with long-term outcome of major depressive disorder. The goal of this study was to examine whether CBT would help maintain attributional style changes experienced by patients during acute phase fluoxetine treatment. METHOD: Three hundred and ninety-one patients with major depressive disorder were enrolled in an open, fixed-dose 8 week fluoxetine trial. Remitters to this acute phase treatment (N= 132) were randomized to receive either fixed-dose fluoxetine (meds only) or fixed-dose fluoxetine plus cognitive-behavioural therapy (CBT+meds) during a 6-month continuation treatment phase. The Attributional Style Questionnaire (ASQ) was completed by patients at three time points - acute phase baseline, continuation phase baseline and continuation phase endpoint. Analysis of covariance was used to compare continuation phase ASQ composite score changes between groups. RESULTS: Patients in both treatment groups experienced significant gains in positive attributional style during the acute phase of treatment. Continuation phase ASQ composite change scores differed significantly between treatment groups, with the CBT + meds group maintaining acute phase positive attributional style changes, and the meds only group exhibiting a worsening of attributional style. The two treatment groups did not significantly differ in rates of relapse and final continuation phase visit HAMD-17 scores. CONCLUSIONS: In this sample, the addition of CBT to continuation psychopharmacological treatment was associated with maintenance of acute treatment phase attributional style gains. Further research is needed to evaluate the role of such gains in the long-term course of depressive illness.

Clinical and sociodemographic predictors of response to augmentation, or dose increase among depressed outpatients resistant to fluoxetine 20 mg/day.

OBJECTIVE: Patients with major depressive disorder often show only partial or no response to antidepressants, necessitating next-step interventions such as dose increase or augmentation. Factors moderating response to these next-step interventions are not well-studied. METHOD: In this randomized, double-blind investigation of next-step treatments in 101 outpatients who failed to respond to fluoxetine 20 mg for 8 weeks, the impact of depressive course and sociodemographic factors on likelihood of treatment response following dose increase or lithium or desipramine augmentation was examined. RESULTS: After controlling for depression severity at baseline, current marriage and earlier onset of depression were associated with greater likelihood of response in a logistic regression. Intervention strategy was not predictive of response. CONCLUSION: Marital status and earlier onset of depression may be clinically useful in predicting outcome following any next-step intervention for treatment resistance, rather than with particular strategies.

Personality disorders and depression.

BACKGROUND: Personality disorders (PDs) were assessed among depressed out-patients by clinical interview before and after antidepressant treatment with fluoxetine to assess the degree of stability of PD diagnoses and determine whether changes in PD diagnoses across treatment are related to the degree of improvement in depressive symptoms. METHOD: Three hundred and eighty-four out-patients (55% women; mean age = 39.9 +/- 10.5) with major depressive disorder (MDD) diagnosed with the SCID-P were enrolled into an 8 week trial of open treatment with fluoxetine 20 mg/day. The SCID-II was administered to diagnose PDs at baseline and endpoint. RESULTS: A significant proportion (64%) of our depressed out-patients met criteria for at least one co-morbid personality disorder. Following 8 weeks of fluoxetine treatment, there was a significant reduction in the proportion of patients meeting criteria for avoidant, dependent, passive-aggressive, paranoid and narcissistic PDs. From baseline to endpoint, there was also a significant reduction in the mean number of criteria met for paranoid, schizotypal, narcissistic, borderline, avoidant, dependent, obsessive-compulsive, passive aggressive and self-defeating personality disorders. While changes in cluster diagnoses were not significantly related to improvement in depressive symptoms, there were significant relationships between degree of reduction in depressive symptoms (percentage change in HAM-D-17 scores) and degree of change in the number of criteria met for paranoid, narcissistic, borderline and dependent personality disorders. CONCLUSIONS: Personality disorder diagnoses were found to be common among untreated out-patients with major depressive disorder. A significant proportion of these patients no longer met criteria for personality disorders following antidepressant treatment, and changes in personality disorder traits were significantly related to degree of improvement in depressive symptoms in some but not all personality disorders. These findings suggest that the lack of stability of PD diagnoses among patients with current MDD may be attributable in part to a direct effect of antidepressant treatment on behaviours and attitudes that comprise PDs.

Use of the five-factory inventory in characterizing patients with major depressive disorder.

Research on personality traits has suggested an association between depression and certain personality traits, such as neuroticism and extraversion. Costa and McCrae's five-factor personality inventory (NEO) has been shown to measure personality traits in a nonclinical population, but its use has not been fully explored in clinical populations. This study aims to compare NEO results in a sample of depressed outpatients with published test norms, and determine if different levels of neuroticism and extraversion are associated with differences in certain psychosocial and clinical characteristics. Seventy-six depressed outpatients participating in antidepressant clinical trials completed this self-report questionnaire before beginning pharmacological treatment. Diagnosis of major depressive disorder (MDD) was made using the Structured Clinical Interview for DSM-III-R or DSM-IV and the severity of depression was measured with the 17-item Hamilton Depression Rating Scale (HAM-D). The three analyses conducted were as follows: (1) NEO factor scores were compared with published normative means; (2) three groups, based on level of neuroticism, were compared on certain psychosocial and clinical characteristics; and (3) three groups, based on level of extraversion, were compared on the same psychosocial and clinical characteristics. Both the males and females obtained T score values for the Neuroticism Scale 1.5 SD above the mean, for the Extraversion Scale 1.5 SD below the mean, and for the Conscientiousness Scale 1.5 SD below the mean. No significant differences were found between subjects with different levels of neuroticism and extraversion, although a trend did exist indicating a positive relationship between neuroticism and severity of depression. Depressed outpatients experience frequent negative affects, have irrational thought processes, cope with stress poorly, have difficulty controlling impulses, prefer to be alone, and have difficulty carrying out tasks. Future studies should examine how such personality factors affect response to treatment and course of illness.

Strengthening clinical effectiveness trials: equipoise-stratified randomization.

As psychiatric practice patterns evolve to take advantage of the growing list of treatments with proven efficacy, research studies with broader aims will become increasingly important. Randomized trials may need to accommodate multiple treatment options. In completely randomized designs, patients are assigned at random to one of the options, requiring that patients and clinicians find each of the options acceptable. In "clinician's choice" designs, patients are randomized to a small number of broad strategies and the choice of specific option within the broad strategy is left up to the clinician. The clinician's choice design permits some scope to patient and clinician preferences, but sacrifices the ability to make randomization-based comparisons of specific options. We describe a new approach, which we call the "equipoise stratified" design, that merges the advantages and avoids the disadvantages of the other two designs for clinical trials. The three designs are contrasted, using the National Institute of Mental Health Sequenced Treatment Alternatives to Relieve Depression trial as an example.

Physicians' knowledge, attitudes, and practice of pharmacologic treatment of hypertension.

OBJECTIVE: To explore how well physicians who treat hypertension know the indications and contraindications for particular antihypertensive therapies, and how closely their opinions and practice of hypertension treatment agree with national guidelines. METHODS: We surveyed by mail a stratified random sample of 10,000 US cardiologists, internists, and general/family practitioners. This survey explored their knowledge, attitudes, and practices with respect to the treatment of hypertension. Responses were compared with national guidelines and product labeling at the time of the survey. Results were stratified by physician specialty. RESULTS: A total of 1,023 physicians, or 10.2% of the sample, responded to the survey. Only 37.3% answered all four knowledge questions correctly, including 25.7% of general/family practitioners, 38.3% of internists, and 49.5% of cardiologists (p < 0.001). In their attitudes with respect to evaluating high blood pressure and establishing treatment goals, most respondents agreed with established guidelines. However, when asked how they would treat uncomplicated, mild hypertension, only 23% limited their selection to diuretics and beta-blockers in accordance with the guidelines. Cardiologists in particular were more likely than internists or general/family practitioners to choose other drug classes, such as angiotensin-converting enzyme Inhibitors or calcium-channel blockers. CONCLUSIONS: The results of our survey suggest that national efforts to educate physicians about the increasingly complex armamentarium for hypertension, and to persuade them to base their prescribing on the results of randomized, controlled trials of primary prevention, must be continued.
