Abstract
In England, the prescribing of antidepressants, primarily the newer generation antidepressant classes, has steadily increased over recent years. There is ongoing debate about how the efficacy of these drugs is viewed, their place in therapy and the harms associated with stopping them. Much of the evidence of their efficacy comes from short-term placebo-controlled trials which tend not to include outcomes that are of greatest relevance to patients, such as social functioning or quality of life, but rather restrict outcomes narrowly to symptom measures. On such measures these studies do not demonstrate clinically significant differences from placebo for depression. A range of adverse effects are also recognised, often greater in naturalistic studies of long-term antidepressants users than those measured in short-term efficacy studies, including emotional numbing, sexual difficulties, fatigue and weight gain. There is increasing recognition that withdrawal symptoms from antidepressants are common and that these symptoms can be severe and long-lasting in some patients. Recent guidance on how to stop antidepressants in a tolerable way has been presented by the Royal College of Psychiatrists. We believe that increasing awareness about the difficulty that some patients have in stopping antidepressants should lead to more cautious prescribing practice, with antidepressants given to fewer patients and for shorter periods of time. This article discusses the perceived benefits and harms of antidepressant use.

Ulleberg P, Berge T, Lending HD, Skule C, Landrø NI. Is perceived control of depression related to therapy outcome for depression? A longitudinal study. J Psychiatr Res 2021; 140:504-511. [PMID: 34157589 DOI: 10.1016/j.jpsychires.2021.06.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 06/04/2021] [Accepted: 06/13/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND The present study followed a group of patients over a two-year period after they had received a cognitive behavioral psychoeducational intervention targeting patients' ability to cope with depression. The main aims were to examine whether a change in both depressive symptoms and in the perceived control of depression occurred and the relationship between depressive symptoms and perceived control. METHODS Using a prospective longitudinal design, a sample of 183 patients was assessed at four time points during a two-year period. RESULTS The patients showed a large reduction in depressive symptoms over the two-year period after the course ended. During the same time period, perceived controllability of depression increased. A parallel latent growth curve model showed that increased control beliefs were related to reduced depressive symptoms. The decrease in depressive symptoms over time was not dependent on the patients' initial level of depression or initial control of depression, use of medication, duration of previous depressive episodes, alcohol use or sociodemographic variables. CONCLUSION Group interventions aimed at increasing coping skills for preventing and mastering of depression may lead to a large and stable reduction in depressive symptoms. A key factor in prevention may be to strengthen patients' perceived ability to cope with the different symptoms of depression.

Abstract
Chronic diseases commonly entail disability and are highly comorbid with mental health problems, particularly depression. Prevalence of depression across different disabling conditions affecting adult patients, as well as risk factors for depression in these patient groups are reviewed in the current work, with a particular focus on the literature published in the past 5 years. The prevalence of depression in disabling conditions is higher than in the general population and is associated with different factors. Examples of disease-specific factors include neurological implications of stoke, diabetic related conditions (e.g. amputation), limitations imposed by vision loss caused by age-related eye diseases, fatigue in rheumatoid arthritis, and pain in cancer. Common factors identified across different conditions include pre-morbid depression, history of mental health problems, poor social support, disease-related disability, multi-morbidity, and less adaptive coping strategies. We also reviewed studies suggesting a potential bidirectional relationship between depression and chronic disease, particularly for stroke, cardiovascular disease, diabetes, and potential factors mediating that relationship. Current findings suggested that long-term depression might be associated with an increased risk of subsequent physical health problems, although the nature of that relationship and its underlying mechanisms are still unclear.

Abstract
Relevance: Understanding patients' informational needs and adapting drug-related information are the prerequisites for a contextualized informed consent. Current information practices might rather harm by inducing nocebo effects. Objective: To investigate whether informing about the nocebo effect using a short information sheet affects patients' need for information about antidepressants. Methods: A total of 97 patients taking recently prescribed antidepressants (≤4 months intake) were recruited over the internet and randomized to receiving either a one-page written information about the nocebo effect or a control text about the history of antidepressants. After experimental manipulation, informational needs about the side effects and mechanisms of antidepressants were assessed with 3 and 7 items on categorical and 5-point Likert scales. Group differences in informational needs were calculated with Chi-square tests and ANOVAs. Results: Patients received antidepressants for depression (84.5%) and/or anxiety disorders (42.3%). Three participants (6.0%) of the nocebo group reported previous knowledge of the nocebo effect. After the experimental manipulation, participants in the nocebo group reported a reduced desire for receiving full side effect information [X ( 4 , 97 ) 2 = 12.714, Cramer's V = 0.362, p = 0.013] and agreed more frequently to the usefulness of withholding information about possible side effects [X ( 4 , 97 ) 2 = 14.878, Cramer's V = 0.392, p = 0.005]. Furthermore, they desired more information about the mechanisms of antidepressants (F = 6.373, p = 0.013, partial η2 = 0.063) and, specifically, non-pharmacological mechanisms, such as the role of positive expectations (F = 16.857, p < 0.001, partial η2 = 0.151). Conclusions: Learning about the nocebo effect can alter patients' informational needs toward desiring less information about the potential side effects of antidepressants and more information about general mechanisms, such as expectations. The beneficial effects of including nocebo information into contextualized informed consent should be studied clinically concerning more functional information-seeking behavior, which may ultimately lead to improved treatment outcomes, such as better adherence and reduced side effect burden.

Hengartner MP. How effective are antidepressants for depression over the long term? A critical review of relapse prevention trials and the issue of withdrawal confounding. Ther Adv Psychopharmacol 2020; 10:2045125320921694. [PMID: 32435449 PMCID: PMC7225779 DOI: 10.1177/2045125320921694] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Accepted: 03/27/2020] [Indexed: 12/20/2022] Open
Abstract
The aim of this article is to discuss the validity of relapse prevention trials and the issue of withdrawal confounding in these trials. Recommendations for long-term antidepressant treatment are based almost exclusively on discontinuation trials. In these relapse prevention trials, participants with remitted depression are randomised either to have the antidepressant abruptly discontinued and replaced by inert placebo or to continue active treatment. The drug-placebo difference in relapse rates at the end of the maintenance phase is then interpreted as a prophylactic drug effect. These trials consistently produce remarkable benefits for maintenance treatment. However, the internal validity of this trial protocol is compromised, as research has shown that abruptly stopping antidepressants can cause severe withdrawal reactions that lead to (or manifest as) depression relapses. That is, there is substantial withdrawal confounding in discontinuation trials, which renders their findings uninterpretable. It is not clear to what degree the drug-placebo separation in relapse prevention (discontinuation) trials is due to withdrawal reactions, but various estimations suggest that it is presumably the majority. A review of findings based on other methodologies, including real-world long-term effectiveness trials like STAR*D and various naturalistic cohort studies, do not indicate that antidepressants have considerable prophylactic effects. As absence of evidence does not imply evidence of absence, no definitive conclusions can be drawn from the literature. To enable a thorough risk-benefit evaluation, real-world effectiveness trials should not only focus on relapse prevention, but also assess antidepressants' long-term effects on social functioning and quality of life. Thus far, reliable long-term data on these outcome domains are lacking.

Abstract
INTRODUCTION Psychological interventions and antidepressant medication can be effective interventions to prevent depressive relapse for patients currently in remission of depression. Less is known about overall factors that predict or moderate treatment response for patients receiving a psychological intervention for recurrent depression. This is a protocol for an individual participant data (IPD) meta-analysis which aims to assess predictors and moderators of relapse or recurrence for patients currently in remission from depression. METHODS AND ANALYSIS Searches of PubMed, PsycINFO, Embase and Cochrane Central Register of Controlled Trials were completed on 13 October 2019. Study extractions and risk of bias assessments have been completed. Study authors will be asked to contribute IPD. Standard aggregate meta-analysis and IPD analysis will be conducted, and the outcomes will be compared with assess whether results differ between studies supplying data and those that did not. IPD files of individual data will be merged and variables homogenised where possible for consistency. IPD will be analysed via Cox regression and one and two-stage analyses will be conducted. ETHICS AND DISSEMINATION The results will be published in peer review journals and shared in a policy briefing as well as accessible formats and shared with a range of stakeholders. The results will inform patients and clinicians and researchers about our current understanding of more personalised ways to prevent a depressive relapse. No local ethics approval was necessary following consultation with the legal department. Guidance on patient data storage and management will be adhered to. PROSPERO REGISTRATION NUMBER CRD42019127844.

Abstract
BACKGROUND Antidepressant medications (ADMs) are widely used and long-term use is increasing. Given this extensive use and recommendation of ADMs in guidelines, one would expect ADMs to be universally considered effective. Surprisingly, that is not the case; fierce debate on their benefits and harms continues. This editorial seeks to understand why the controversy continues and how consensus can be achieved. METHODS 'Position' paper. Critical analysis and synthesis of relevant literature. RESULTS Advocates point at ADMs impressive effect size (number needed to treat, NNT = 6-8) in acute phase treatment and continuation/maintenance ADM treatment prevention relapse/recurrence in acute phase ADM responders (NNT = 3-4). Critics point at the limited clinically significant surplus value of ADMs relative to placebo and argue that effectiveness is overstated. We identified multiple factors that fuel the controversy: certainty of evidence is low to moderate; modest efficacy on top of strong placebo effects allows critics to focus on small net efficacy and advocates on large gross efficacy; ADM withdrawal symptoms masquerade as relapse/recurrence; lack of association between ADM treatment and long-term outcome in observational databases. Similar problems affect psychological treatments as well, but less so. We recommend four approaches to resolve the controversy: (1) placebo-controlled trials with relevant long-term outcome assessments, (2) inventive analyses of observational databases, (3) patient cohort studies including effect moderators to improve personalized treatment, and (4) psychological treatments as universal first-line treatment step. CONCLUSIONS Given the public health significance of depression and increased long-term ADM usage, new approaches are needed to resolve the controversy.

Abstract
The forthcoming National Institute for Health and Care Excellence depression guideline reviews short-term outcomes for long-term depression. We present effect sizes for long-term outcomes in trials that report these data. Psychological therapies become more effective, whereas antidepressants become less effective over the long term. We review other forms of longitudinal research that support these findings.

Abstract
PURPOSE To review and synthesise prognostic indices that predict subsequent risk, prescriptive indices that moderate treatment response, and mechanisms that underlie each with respect to relapse and recurrence of depression in adults. RESULTS AND CONCLUSIONS Childhood maltreatment, post-treatment residual symptoms, and a history of recurrence emerged as strong prognostic indicators of risk and each could be used prescriptively to indicate who benefits most from continued or prophylactic treatment. Targeting prognostic indices or their "down-stream" consequences will be particularly beneficial because each is either a cause or a consequence of the causal mechanisms underlying risk of recurrence. The cognitive and neural mechanisms that underlie the prognostic indices are likely addressed by the effects of treatments that are moderated by the prescriptive factors. For example, psychosocial interventions that target the consequences of childhood maltreatment, extending pharmacotherapy or adapting psychological therapies to deal with residual symptoms, or using cognitive or mindfulness-based therapies for those with prior histories of recurrence. Future research that focuses on understanding causal pathways that link childhood maltreatment, or cognitive diatheses, to dysfunction in the neocortical and limbic pathways that process affective information and facilitate cognitive control, might result in more enduring effects of treatments for depression.

Abstract
OBJECTIVES To measure persistence and nonrecurrence of depression treatment and investigate potential risk factors. METHODS We retrospectively observed a closed cohort of insurees with new-onset depression treatment in 2007 and without most psychiatric comorbidity for 16 quarters (plus one to ascertain discontinuation). We linked inpatient/outpatient/drug-data per person and quarter. Person-quarters containing specified depression services were classified as depression-treatment-person-quarters (DTPQ). We defined longterm-DTPQ-persistence as 16 + 1 continuous DTPQ and longterm-DTPQ-nonrecurrence as 12 continuous quarters without DTPQ and used multivariate logistic regression to explore associations with these outcomes. RESULTS Within first 16 quarters, 28,348 patients' first period (total time) persisted for a mean/median 5.4/3 (8.7/8) quarters. Fourteen percent had longterm-DTPQ-persistence, associated (p < .05) with baseline hospital (odds ratio, OR = 1.80), psychotherapy/specialist-interview and antidepressants (OR = 1.81), age (years, OR = 1.03), unemployment (OR = 1.21), retirement (OR = 1.31), and insured as a dependent (OR = 1.32). Thirty-four percent had longterm-DTPQ-nonrecurrence, associated with psychotherapy/specialist-interview (OR = 1.40), antidepressants (OR = 0.54), female sex (OR = 0.84), age (years, OR = 0.99), retirement (OR = 1.18), and insured as a dependent (OR = 0.88). Women differed for episodic and not chronic treatment. CONCLUSION Treatment measures compared to survey's symptoms measures. We suggest further research on "treatment-free-time." Antidepressants(-) and psychotherapy/specialist-interview(+) were significantly associated with longterm-DTPQ-nonrecurrence. This was presumably moderated by possible short-time/low-dosage antidepressants use(-) and selective therapy assignment(+). Sample selectivity limited data misclassification.

Abstract
Heart rate variability (HRV) is a significant marker of health outcomes with decreased HRV predicting increased disease risk. HRV is decreased in major depressive disorder (MDD) but existing treatments for depression do not return heart rate variability to normal levels even with successful treatment of depression. Heart rate variability biofeedback (HRVB) increases heart rate variability but no studies to date have examined whether combining HRVB with psychotherapy improves outcome in MDD treatment. The present study used a randomized controlled design to compare the effects of HRVB combined with psychotherapy on MDD relative to a psychotherapy treatment as usual group and to a non-depressed control group. The HRVB+psychotherapy group showed a larger increase in HRV and a larger decrease in depressive symptoms relative to the other groups over a six-week period, whereas the psychotherapy group only did not improve HRV. Results support the supplementation of psychotherapy with HRVB in the treatment of MDD.

Abstract
OBJECTIVE Individuals undergoing long-term psychiatric treatment frequently choose to stop taking psychiatric medications. To enhance service user choice and prevent undesirable outcomes, this first U.S. survey of a large sample of longer-term users sought to increase knowledge about users' experience of medication discontinuation. METHODS A sample of 250 U.S. adults with a diagnosis of serious mental illness and a recent goal to stop up to two prescribed psychiatric medications, which they had taken for at least nine months, completed a web-based survey about experiences, strategies, and supports during discontinuation. RESULTS About half (54%) met their goal of completely discontinuing one or more medications; 46% reported another outcome (use was reduced, use increased, or use stayed the same). Concerns about medications' effects (for example, long-term effects and side effects) prompted the decision to discontinue for 74% of respondents. They used various strategies to cope with withdrawal symptoms, which 54% rated as severe. Self-education and contact with friends and with others who had discontinued or reduced medications were most frequently cited as helpful. Although more than half rated the initial medication decision with prescribers as largely collaborative, only 45% rated prescribers as helpful during discontinuation. Of respondents who completely discontinued, 82% were satisfied with their decision. CONCLUSIONS Discontinuing psychiatric medication appears to be a complicated and difficult process, although most respondents reported satisfaction with their decision. Future research should guide health care systems and providers to better support patient choice and self-determination regarding the use and discontinuation of psychiatric medication.

Psychotherapy Versus Pharmacotherapy of Depression: What's the Evidence? ZEITSCHRIFT FUR PSYCHOSOMATISCHE MEDIZIN UND PSYCHOTHERAPIE 2017; 62:190-5.

Abstract
OBJECTIVES Depression may be treated by psychotherapy or pharmacotherapy or their combination. There is an ongoing debate whether one of these approaches is possibly superior. A recent meta-analysis reported results in favour of pharmacotherapy. METHODS Individual studies and meta-analyses on the comparative efficacy of psychotherapy vs. pharmacotherapy were reviewed. RESULTS Evidence suggests that psychotherapy and pharmacotherapy are equally efficacious in the short-term, but psychotherapy is superior in the long-term. For the recently stated hypothesis that pharmacotherapy is superior to psychotherapy in studies without a pill placebo condition, which implies equally including a positive expectancy effect for both pharmacotherapy and psychotherapy no evidence was found. CONCLUSION Depression may be treated by psychotherapy or pharmacotherapy with equivalent results in the short-term and advantages for psychotherapy in the long-term. As the rates of response and remission are still limited in both treatments, further improvement of treatments is required.

Abstract
BACKGROUND In current psychiatric practice, antidepressants are widely and with ever-increasing frequency prescribed to patients. However, several scientific biases obfuscate estimates of antidepressants' efficacy and harm, and these are barely recognized in treatment guidelines. The aim of this mini-review is to critically evaluate the efficacy and harm of antidepressants for acute and maintenance treatment with respect to systematic biases related to industry funding and trial methodology. METHODS Narrative review based on a comprehensive search of the literature. RESULTS It is shown that the pooled efficacy of antidepressants is weak and below the threshold of a minimally clinically important change once publication and reporting biases are considered. Moreover, the small mean difference in symptom reductions relative to placebo is possibly attributable to observer effects in unblinded assessors and patient expectancies. With respect to trial dropout rates, a hard outcome not subjected to observer bias, no difference was observed between antidepressants and placebo. The discontinuation trials on the efficacy of antidepressants in maintenance therapy are systematically flawed, because in these studies, spontaneous remitters are excluded, whereas half of all patients who remitted on antidepressants are abruptly switched to placebo. This can cause a severe withdrawal syndrome that is easily misdiagnosed as a relapse when assessed on subjective symptom rating scales. In accordance, the findings of naturalistic long-term studies suggest that maintenance therapy has no clear benefit, and non-drug users do not show increased recurrence rates. Moreover, a growing body of evidence from hundreds of randomized controlled trials suggests that antidepressants cause suicidality, but this risk is underestimated because data from industry-funded trials are systematically flawed. Unselected, population-wide observational studies indicate that depressive patients who use antidepressants are at an increased risk of suicide and that they have a higher rate of all-cause mortality than matched controls. CONCLUSION The strong reliance on industry-funded research results in an uncritical approval of antidepressants. Due to several flaws such as publication and reporting bias, unblinding of outcome assessors, concealment and recoding of serious adverse events, the efficacy of antidepressants is systematically overestimated, and harm is systematically underestimated. Therefore, I conclude that antidepressants are largely ineffective and potentially harmful.

Abstract
Depression and anxiety are undertreated and represent a growing health crisis and economic burden. Current treatment approaches (medications, psychotherapy) appear insufficient to resolve these problems. Difficulties with current treatment approaches include cost, side effects, and stigma. Given that depression and anxiety share significant features and a common etiology in chronic stress, an effective approach to reduce depression and anxiety may be to reduce chronic stress. Chronic stress is on the rise, with more than one third of Americans reporting high levels of stress with which they feel they cannot adequately cope. Treating chronic stress at the population level has the potential to reduce the rising tide of depression and anxiety. Biofeedback and mindfulness are two interventions that demonstrably reduce stress and negative mood, are cost and time-effective, have no side effects, and have minimal stigma relative to medications and psychotherapy.

Abstract
BACKGROUND With a healthcare system burdened by symptomatic and mental-health related conditions, the placebo effect may represent a useful clinical tool. First, however, there is a need to broaden research attention and investigate placebo effects outside laboratories and beyond experimental pain. This study investigated the effectiveness of a take-home placebo treatment in the short-term alleviation of stress, anxiety and symptoms of depression in a non-patient population. METHOD A sample of 77 participants was randomized to either the 'oxytocin' treatment group (n = 22), the 'serotonin' treatment group (n = 22) or the wait-list control group (n = 33). The two treatment groups were given an 'anti-stress treatment spray' (placebo) to self-administer for 3 days, and completed online measures of perceived stress (Perceived Stress Scale-10), anxiety (Cognitive Somatic Anxiety Questionnaire) and symptoms of depression (Centre for Epidemiological Studies - Depression) before and after the 3-day protocol. RESULTS Both the 'serotonin' and 'oxytocin' treatment sprays were effective in reducing symptoms of depression; however, only those in the 'oxytocin' group reported less stress and anxiety as compared with controls. Overall, the 'oxytocin' was perceived as more effective. CONCLUSION Placebo effects can be translated to a real-life setting in the short-term reduction of stress, anxiety and symptoms of depression in a non-patient population. In treating psychological distress, placebos may be useful addition to the treatment repertoire. The information given with treatment may also be an important consideration for practitioners.

Abstract
Long-term antidepressant treatment has increased and there is evidence of adverse effects; however, little is known about patients' experiences and views of this form of treatment. This study used mixed methods to examine patients' views and experiences of long-term antidepressant treatment, including benefits and concerns. Data from 180 patients, who were long-term users of antidepressants (3-15 years), were extracted from an anonymous online survey of patients' experiences of antidepressants in New Zealand. Participants had completed rating scales about the effectiveness of antidepressants, levels of depression before and during antidepressant use, quality of life, and perceived adverse effects. Two open-ended questions allowed participants to comment on personal experiences. The majority (89.4%) reported that antidepressants had improved their depression although 30% reported moderate-to-severe depression on antidepressants. Common adverse effects included withdrawal effects (73.5%), sexual problems (71.8%), and weight gain (65.3%). Adverse emotional effects, such as feeling emotionally numb (64.5%) and addicted (43%), were also common. While the majority of patients were pleased with the benefits of antidepressant treatment, many were concerned about these adverse effects. Some expressed a need for more information about long-term risks and increased information and support to discontinue.

Abstract
Background Depressive disorder is recognized as recurrent or chronic in the majority of affected individuals; but literature is not consistent about determinants of the disorder course. Aims To analyse the relationships between familial, personal and environmental characteristics in different life phases and their effects on the chronicity of depression in a population-based sample. Methods It was a longitudinal panel study with three waves (W1-W3) for 651 adult men and women with diagnosis of minor/major depression or dysthymia at W1 of the Swedish PART (mental health, work and relations) study. Risk factors and co-morbidities were assessed with questionnaires. The main outcome was an episode of minor/major depression or dysthymia at 10-12 years of follow-up (W3). Liability for depressive episodes was determined using exploratory structural equation modelling (SEM), following a path approach with step-wise specification searches. Results Most of the risk factors determined, directly or indirectly, depression severity at W3. Somatic trait anxiety, partner loss and other negative life events at W1, depressive symptoms at W2, and life difficulties and other dependent life events at W3 had direct effects on the outcome. Conclusions SEM model revealed complex and intertwined psychopathological pathways leading to chronicity of depression, given previous episodes, which could be assembled in two main mechanisms: a depressive-internalizing path and an adversity path comprised of life events. Pathways are simpler than those of depression occurrence, emphasizing the relevance of personality factors as depression determinants, and excluding disability levels, co-morbidities and social support. These novel findings need to be replicated in future studies.

Abstract
BACKGROUND Depression, anxiety, and emotional distress occur frequently and are usually treated in general practice. Little has been reported about the long-term course of these conditions and the long-term use of medical services. AIM To follow up patients with depression, anxiety, and emotional distress in general practice for 5 years and examine the length and number of index episodes, prescribing behaviour, and the use of services in general practice. DESIGN AND SETTING A case-control study using data from electronic medical records. METHOD Three cohorts of patients with depression (n = 453), anxiety (n = 442), and emotional distress (n = 185) were compared against a cohort of control patients (n = 4156) during a 5-year follow-up from 2007 to 2011. The occurrence or recurrence of the index disorders, other psychological disorders or medical conditions, the numbers of prescriptions, and the number of contacts with the general practice were all examined. RESULTS Patients in the depression group had 1.1 followup episodes of depression, those in the anxiety group had 0.9 follow-up episodes of anxiety, and those in the emotional distress group had 0.5 follow-up episodes of emotional distress during the 5 years. All three groups had more consultations (for both psychological and somatic reasons) during each of the follow-up years than control patients. Furthermore, the groups with mental health disorders were given more prescriptions for psychopharmacological treatment. CONCLUSION Five years after the index episode in 2007, patients with an episode of depression, anxiety, or emotional distress are still not comparable with control patients, in terms of the prevalence of mental health conditions, the number of prescriptions, and healthcare use.

Abstract
Two different and seemingly competing views on the diagnosis of major depressive disorder (MDD) exist. The first is that the diagnosis conflates adaptive sadness reactions with pathological states of depressed mood and that MDD is overdiagnosed and overtreated. The second is that MDD is an underdiagnosed and undertreated disorder, and one that is best characterised by a severe, chronic, recurrent or treatment-resistant course. Existing research suggests that both views are valid and merit being integrated. Anywhere from 30 to 50% of individuals will meet criteria for MDD at some point in their life. About half of these episodes are of brief duration and unlikely to recur. However, a remaining half is either chronic or recurrent. Data on the outpatient diagnosis of depression support the view that depression is simultaneously underdiagnosed and undertreated as well as overdiagnosed and overtreated. About one-third of the patients who meet criteria for MDD and receive placebos experience clinically significant and long-lasting improvement. Many other patients, however, are unresponsive to one or multiple active treatments. Thus, the diagnosis of MDD likely applies to individuals who are experiencing either normal periods of sadness or single-episode afflictions that are mild, unlikely to recur, and are placebo responsive, as well as to individuals with more severe clinical profiles. More research is needed that can help ascertain what contextual or biopsychological variables help distinguish between individuals who may be experiencing adaptive states of negative affect and those who experience severe, chronic, recurrent or treatment-resistant depressions.

Abstract
BACKGROUND Long-term symptomatic status in persons with major depressive and bipolar disorders treated clinically is not well established, although mood disorders are leading causes of disability worldwide. AIMS To pool data on long-term morbidity, by type and as a proportion of time-at-risk, based on published studies and previously unreported data. METHODS We carried out systematic, computerized literature searches for information on percentage of time in specific morbid states in persons treated clinically and diagnosed with recurrent major depressive or bipolar I or II disorders, and incorporated new data from one of our centers. RESULTS We analyzed data from 25 samples involving 2479 unipolar depressive and 3936 bipolar disorder subjects (total N=6415) treated clinically for 9.4 years. Proportions of time ill were surprisingly and similarly high across diagnoses: unipolar depressive (46.0%), bipolar I (43.7%), and bipolar II (43.2%) disorders, and morbidity was predominantly depressive: unipolar (100%), bipolar-II (81.2%), bipolar-I (69.6%). Percent-time-ill did not differ between UP and BD subjects, but declined significantly with longer exposure times. CONCLUSIONS The findings indicate that depressive components of all major affective disorders accounted for 86% of the 43-46% of time in affective morbidity that occurred despite availability of effective treatments. These results encourage redoubled efforts to improve treatments for depression and adherence to their long-term use.

Abstract
CONTEXT There is evidence that psychotherapy is helpful in depressive disorders, with no significant differences between psychotherapies. For psychodynamic therapy (PDT) various models prove to be efficacious. Thus, the evidence for PDT is "scattered" between different forms of PDT, also implying problems in training of psychotherapy and in transferring research to clinical practice. A unified protocol based on empirically-supported methods of PDT in depression may contribute to solve these problems METHODS Systematic search for randomized controlled trials fulfilling the following criteria: (a) individual psychodynamic therapy (PDT) of depressive disorders, (b) treatment manuals or manual-like guidelines, (c) PDT proved to be efficacious compared to control conditions, (d) reliable measures for diagnosis and outcome, and (f) adult patients. FINDINGS Fourteen RCTs fulfilled the inclusion criteria. By a systematic review of the applied methods of PDT seven treatment components were identified. A high consistency between components was found. The components were conceptualized in the form of seven interrelated treatment modules. CONCLUSIONS A unified psychodynamic protocol for depression may enhance the empirical status of PDT, facilitate both the training in psychotherapy and the transfer of research to clinical practice and may have an impact on the health care system.

Abstract
In randomized controlled trials, maintenance treatment for relapse prevention has been proven to be efficacious in patients responding in acute treatment, its efficacy in long-term outcome in "real-world patients" has yet to be proven. Three-year long-term data from a large naturalistic multisite follow-up were presented. Severe relapse was defined as suicide, severe suicide attempt, or rehospitalization. Next to relapse rates, possible risk factors including antidepressant medication were identified using univariate generalized log-rank tests and multivariate Cox proportional hazards model for time to severe relapse. Overall data of 458 patients were available for analysis. Of all patients, 155 (33.6%) experienced at least one severe relapse during the 3-year follow-up. The following variables were associated with a shorter time to a severe relapse in univariate and multivariate analyses: multiple hospitalizations, presence of avoidant personality disorder, continuing antipsychotic medication, and no further antidepressant treatment. In comparison with other studies, the observed rate of severe relapse during 3-year period is rather low. This is one of the first reports demonstrating a beneficial effect of long-term antidepressant medication on severe relapse rates in naturalistic patients. Concomitant antipsychotic medication may be a proxy marker for treatment resistant and psychotic depression.

Abstract
PURPOSE The aim of this study was to utilize bootstrapping to investigate the robustness of latent class trajectories and risk factors of depressive symptoms among mothers of children with epilepsy. METHODS Data were obtained from a national prospective cohort study (2004-09) of children newly diagnosed with epilepsy and their families in Canada (n = 339). Latent classes of depressive symptom trajectories were modeled using a semi-parametric group-based trajectory modeling approach. Multinomial logistic regression identified risk factors predicting trajectory group membership. RESULTS Four trajectories were identified: low stable, borderline, moderate increasing, and high decreasing. Goodness of fit, posterior probabilities, and parameter estimates obtained with bootstrapping were not significantly different from the original sample. Calculation of the root mean square error demonstrated minimal non-ignorable bias for three parameter estimates, which was subsequently removed with additional sampling. Risk factors identified were identical for the original sample and the bootstrap, and differences in odds ratios, as calculated with the method of variance estimation recovery, were not significant. CONCLUSIONS As examined using a bootstrapping procedure, group-based trajectory modeling offers a robust methodology to uncover potential heterogeneity in populations and identify high-risk individuals.

Abstract
Current antidepressants are crude compared with the ideal and patents on most have expired. There are therefore strong clinical and commercial pressures for new drugs to replace them. The prospects for this are, however, now markedly reduced as several major pharmaceutical companies have abandoned work in this area whilst many others have sharply decreased their research investment. These changes and the lack of progress over such a long period are indicative of a catastrophic systems failure which, it is argued, has been caused in large part by a logical flaw at the animal modelling stage. This tautology has served to lock the current antidepressant drug discovery process into an iterative loop capable only of producing further variations of that which has gone before. Drugs produced by this approach have proved to be only poorly effective in the context of the clinically depressed population as a whole. Hence, the inevitable failure of the current antidepressant drug discovery process has left little behind that can be salvaged. Therefore, it is suggested that this be urgently reformulated on more rational grounds using more appropriate species in new animal models based upon a thorough understanding of the behavioural expressions of depression in the clinic.

Previous research into the predictors of chronic depression has focused primarily on the clinical features of the disease; however, little is known about the broader spectrum of sociodemographic and health factors inherent in its development. Our aim was to identify factors associated with a long-term negative prognosis of depression. METHODS We included 585 people aged 16 years and older who participated in the 2000/01 cycle of the National Population Health Survey and who reported experiencing a major depressive episode in 2000/01. The primary outcome was the course of depression until 2006/07. We grouped individuals into trajectories of depression using growth trajectory models. We included demographic, mental and physical health factors as predictors in the multivariable regression model to compare people with different trajectories. RESULTS Participants fell into two main depression trajectories: those whose depression resolved and did not recur (44.7%) and those who experienced repeated episodes (55.3%). In the multivariable model, daily smoking (OR 2.68, 95% CI 1.54-4.67), low mastery (i.e., feeling that life circumstances are beyond one's control) (OR 1.10, 95% CI 1.03-1.18) and history of depression (OR 3.5, 95% CI 1.95-6.27) were significant predictors (p < 0.05) of repeated episodes of depression. INTERPRETATION People with major depression who were current smokers or had low levels of mastery were at an increased risk of repeated episodes of depression. Future studies are needed to confirm the predictive value of these variables and to evaluate their accuracy for diagnosis and as a guide to treatment.

Abstract
OBJECTIVE To evaluate the benefit of pharmacogenetics in antidepressant treatment. METHODS In a simulated trial 100,000 subjects in a current episode of major depressive disorder (MDD) received citalopram or bupropion based on the clinician's decision (algorithm A) or following indications from 5-HTTLPR genetic testing (algorithm B), which effect size of was estimated from a meta-analysis of pharmacogenetic trials. A and B were compared in a cost-utility analysis (12 weeks). Costs (international $, 2010) were drawn from official sources. Treatment effects were expressed as quality-adjusted life weeks (QALWs). Outcome was incremental cost-effectiveness ratio (ICER). RESULTS Under base-case conditions, genetic test use was associated with increases in antidepressant response (0.062 QALWs) and tolerability (0.016 QALWs) but cost benefit was not acceptable (ICER = $2,890; $1,800-$4,091). However, when the joint effect on antidepressant response and tolerability was analyzed in two recurrent episodes, ICER dropped to $1,392 ($837-$1,982). Cost-effectiveness acceptability curve (CEAC) showed a >80% probability that ICER value fell below the commonly accepted 3 times Gross Domestic Product (GDP) threshold (World Health Organization) and therefore suggesting cost-effectiveness. CONCLUSION Notwithstanding some caveats (exclusion of gene-gene and gene-environment interactions; simple 5-HTTLPR architecture), this simulation is favourable to incorporate pharmacogenetic test in antidepressant treatment.

Abstract
Oxytocin (OT) activity increases in response to stress as well as to warm social contact. Subclinical depression is associated with higher stress but less reward from social contacts. The present investigation was intended to examine whether husbands and wives with high depressive symptomatology scores have increased plasma and salivary OT that may be mediated partly by higher perceived stress, and also to assess whether an intervention to convey partner support through "warm touch" may reduce effects of depressive symptoms on OT. In this study, 34 healthy married couples (n=68) ages 20-39 provided self reports of depressive symptoms (CESD) and stress (Perceived Stress Scale) before being randomly assigned to a 4-week intervention study enhancing partner support through "warm touch", or to a "behavior monitoring" control group. Plasma oxytocin levels were obtained pre- and post-intervention, while salivary oxytocin was taken at home during week 1 and week 4. Results revealed that subjects with higher depressive symptoms scores had higher plasma OT levels at pre-intervention, and higher salivary OT levels at home during week 1 (p<.05). Plasma OT results were moderated by gender such that plasma OT levels were highest among females high in depressive symptomology. Higher perceived stress was also linked to both higher depressive symptomatology (r=+65, p<.0001) and plasma OT (p< .05) and a significant mediator. During the intervention, salivary OT remained elevated among subjects high in depressive symptomatology in the control group but not the intervention group. At post-intervention, plasma OT levels in subjects with vs. without depressive symptomatology no longer differed. Results indicate that subclinical depression is associated with elevated plasma and salivary OT levels, which may be mediated in part by increased stress. OT differences linked to subclinical depression were minimized by the warm touch intervention.

Abstract
Dopamine is an important neuromodulator that exerts widespread effects on the central nervous system (CNS) function. Disruption in dopaminergic neurotransmission can have profound effects on mood and behavior and as such is known to be implicated in various neuropsychiatric behavioral disorders including autism and depression. The subsequent effects on other neurocircuitries due to dysregulated dopamine function have yet to be fully explored. Due to the marked social deficits observed in psychiatric patients, the neuropeptide, oxytocin is emerging as one particular neural substrate that may be influenced by the altered dopamine levels subserving neuropathologic-related behavioral diseases. Oxytocin has a substantial role in social attachment, affiliation and sexual behavior. More recently, it has emerged that disturbances in peripheral and central oxytocin levels have been detected in some patients with dopamine-dependent disorders. Thus, oxytocin is proposed to be a key neural substrate that interacts with central dopamine systems. In addition to psychosocial improvement, oxytocin has recently been implicated in mediating mesolimbic dopamine pathways during drug addiction and withdrawal. This bi-directional role of dopamine has also been implicated during some components of sexual behavior. This review will discuss evidence for the existence dopamine/oxytocin positive interaction in social behavioral paradigms and associated disorders such as sexual dysfunction, autism, addiction, anorexia/bulimia, and depression. Preliminary findings suggest that whilst further rigorous testing has to be conducted to establish a dopamine/oxytocin link in human disorders, animal models seem to indicate the existence of broad and integrated brain circuits where dopamine and oxytocin interactions at least in part mediate socio-affiliative behaviors. A profound disruption to these pathways is likely to underpin associated behavioral disorders. Central oxytocin pathways may serve as a potential therapeutic target to improve mood and socio-affiliative behaviors in patients with profound social deficits and/or drug addiction.
