Abstract
Information processing deficits are commonly found in psychiatric illnesses, while at the biochemical level serotonin seems to play a role in nearly all psychiatric disorders. Processing negativity (PN), mismatch negativity (MMN) and P300 amplitude are electrophysiological measures of information processing. The present study was designed to replicate and further extent the results of our initial study on the effects of a low dose of escitalopram (10 mg) on MMN, PN and P300 amplitude. In a randomised, double-blind, cross-over experiment, 20 healthy male volunteers received either a single, orally administered dose of 15 mg escitalopram (a highly selective serotonin reuptake inhibitor (SSRI)) or placebo, after which their PN, MMN and P300 amplitude were assessed. Similar to our initial study with 10 mg escitalopram, 15 mg escitalopram significantly increased MMN, while it did not affect P300 amplitude. In contrast to our initial study, however, the currently higher dose of escitalopram did not increase PN. Results support the view that a broad range of increased serotonergic activity enhances MMN, while the relationship between serotonin and PN seems more complex. The current study does not support a serotonergic involvement in P300 amplitude.

The effectiveness and safety of acupuncture therapy in depressive disorders: systematic review and meta-analysis. J Affect Disord 2010; 124:9-21. [PMID: 19632725 DOI: 10.1016/j.jad.2009.07.005] [Citation(s) in RCA: 139] [Impact Index Per Article: 9.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2009] [Revised: 07/02/2009] [Accepted: 07/02/2009] [Indexed: 11/20/2022]
Abstract
BACKGROUND Although acupuncture has been used as an alternative treatment for depressive disorders, its effectiveness and safety are not well defined. The purpose of this systematic review with meta-analysis was to evaluate the effectiveness of acupuncture as monotherapy and as an additional therapy in treating various depressive conditions, particularly major depressive disorder (MDD) and post-stroke depression (PSD). METHODS Following systematic review, meta-analysis was conducted on high-quality randomized controlled trials (RCTs). RESULTS Of 207 clinical studies of acupuncture for various depression retrieved, 113 (54.6%) were on MDD and 76 (36.7%) on PSD. Twenty RCTs of MDD (n=1998) and 15 of PSD (n=1680) identified for high-quality protocol (Jadad score >or=3) were included for meta-analysis. The efficacy of acupuncture as monotherapy was comparable to antidepressants alone in improving clinical response and alleviating symptom severity of MDD, but not different from sham acupuncture. No sufficient evidence favored the expectation that acupuncture combined with antidepressants could yield better outcomes than antidepressants alone in treating MDD. Acupuncture was superior to antidepressants and waitlist controls in improving both response and symptom severity of PSD. The incidence of adverse events in acupuncture intervention was significantly lower than antidepressants. CONCLUSIONS Acupuncture therapy is safe and effective in treating MDD and PSD, and could be considered an alternative option for the two disorders. The efficacy in other forms of depression remains to be further determined.

Psychotropic drugs have contrasting skeletal effects that are independent of their effects on physical activity levels. Bone 2010; 46:985-92. [PMID: 20060080 PMCID: PMC2842446 DOI: 10.1016/j.bone.2009.12.031] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2009] [Revised: 11/01/2009] [Accepted: 12/29/2009] [Indexed: 11/23/2022]
Abstract
Popular psychotropic drugs, like the antidepressant selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs), and the mood stabilizer lithium, may have skeletal effects. In particular, preclinical observations suggest a direct negative effect of SSRIs on the skeleton. A potential caveat in studies of the skeletal effects of psychotropic drugs is the hypoactive (skeletal unloading) phenotype they induce. The aim of this study was to investigate the contribution of physical inactivity to the skeletal effects of psychotropic drugs by studying bone changes in cage control and tail suspended mice treated with either vehicle, SSRI, TCA or lithium. Tail suspension was used to control for drug differences on physical activity levels by normalizing skeletal loading between groups. The psychotropic drugs were found to have contrasting skeletal effects which were independent of drug effects on animal physical activity levels. The latter was evident by an absence of statistical interactions between the activity and drug groups. Pharmacological inhibition of the 5-hydroxytryptamine (5-HT) transporter (5-HTT) using a SSRI reduced in vivo gains in lower extremity BMD, and negatively altered ex vivo measures of femoral and spinal bone density, architecture and mechanical properties. These effects were mediated by a decrease in bone formation without a change in bone resorption suggesting that the SSRI had anti-anabolic skeletal effects. In contrast, glycogen synthase kinase-3[beta] (GSK-3[beta]) inhibition using lithium had anabolic effects improving in vivo gains in BMD via an increase in bone formation, while TCA-mediated inhibition of the norepinephrine transporter had minimal skeletal effect. The observed negative skeletal effect of 5-HTT inhibition, combined with recent findings of direct and indirect effects of 5-HT on bone formation, are of interest given the frequent prescription of SSRIs for the treatment of depression and other affective disorders. Likewise, the anabolic effect of GSK-3[beta] inhibition using lithium reconfirms the importance of Wnt/beta-catenin signaling in the skeleton and it's targeting by recent drug discovery efforts. In conclusion, the current study demonstrates that different psychotropic drugs with differing underlying mechanisms of action have contrasting skeletal effects and that these effects do not result indirectly via the generation of animal physical inactivity.

Abstract
OBJECTIVE Non-response to treatment with antidepressants (AD) is a clinical problem. METHOD The algorithm for pharmacological treatment of the Dutch multidisciplinary guideline for depression is compared with four other algorithms. RESULTS The Dutch algorithm consists of five subsequent steps. Treatment is started with one out of many optional ADs (step 1); in case of non-response after 4-10 weeks, best evidence is for switching to another AD (step 2); next step is augmentation with lithium as the best option (step 3); the next step is a monoamine oxidase inhibitor (MAOI) (step 4); and finally electroconvulsive therapy (step 5). There are major differences with other algorithms regarding timing of augmentation step, best agents for augmentation and role of MAOI. CONCLUSION Algorithms for AD treatment vary according to national and local preferences. Although the evidence for most of the treatment strategies is rather meagre, an AD algorithm appears to be an useful instrument in clinical practice.

The emerging role of serotonin (5-hydroxytryptamine) in the skeleton and its mediation of the skeletal effects of low-density lipoprotein receptor-related protein 5 (LRP5). Bone 2010; 46:4-12. [PMID: 19591966 PMCID: PMC2818040 DOI: 10.1016/j.bone.2009.06.029] [Citation(s) in RCA: 67] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2009] [Revised: 06/29/2009] [Accepted: 06/30/2009] [Indexed: 10/20/2022]
Abstract
Novel molecular pathways obligatory for bone health are being rapidly identified. One pathway recently revealed involves gut-derived 5-hydroxytryptamine (5-HT) mediation of the complete skeletal effects of low-density lipoprotein receptor-related protein 5 (LRP5). Mounting evidence supports 5-HT as an important regulatory compound in bone with previous evidence demonstrating that bone cells possess functional pathways for responding to 5-HT. In addition, there is growing evidence that potentiation of 5-HT signaling via inhibition of the 5-HT transporter (5-HTT) has significant skeletal effects. The later is clinically significant as the 5-HTT is a popular target of pharmaceutical agents, such as selective serotonin reuptake inhibitors (SSRIs), used for the management of major depressive disorder and other affective conditions. The observation that 5-HT mediates the complete skeletal effects of LRP5 represents a significant paradigm shift from the traditional view that LRP5 located on the cell surface membrane of osteoblasts exerts direct skeletal effects via Wnt/beta-catenin signaling. This paper discusses the mounting evidence for skeletal effects of 5-HT and the ability of gut-derived 5-HT to satisfactorily explain the skeletal effects of LRP5.

Abstract
BACKGROUND Use of antidepressants is the gold standard therapy for major depression. However, despite the large number of commercially available antidepressant drugs there are several differences among them in efficacy, tolerability, and cost-effectiveness. In addition the optimal augmentation strategy is still not clear when dealing with treatment-resistant depression, a condition that affects 15% to 40% of depressed patients. METHODS We therefore reviewed the main characteristics of these drugs regarding their efficacy, tolerability, side effects and cost-effectiveness, by accessing all meta-analyses and systematic reviews published from 2004 to 2009. In addition, we reviewed the augmentation strategy of associated antidepressants with neurostimulation therapies (such as transcranial magnetic stimulation [TMS] and transcranial direct current stimulation [tDCS]). A search was undertaken in MEDLINE, Web of Science, Cochrane, and Scielo databases. We included: 21 meta-analyses of antidepressant trials, 15 neurostimulation clinical trials and 8 studies of pharmacoeconomics. We then performed a comprehensive review on these articles. RESULTS AND CONCLUSION Although recent meta-analyses suggest sertraline and escitalopram might have increased efficacy/tolerability, other studies and large pragmatic trials have not found these to be superior to other antidepressant drugs. Also, we did not identify any superior drug in terms of cost-effectiveness due to the different designs observed among pharmacoecomics studies. Side effects such as sexual dysfunction, gastrointestinal problems and weight gain were common causes of discontinuation. Tolerability was an important issue for novel neurostimulation interventions, such as TMS and tDCS. These therapies might be interesting augmentation strategies, considering their benign profile of side effects, if proper safety parameters are adopted.

Abstract
BACKGROUND Mood and anxiety disorders pose significant health burdens on the community. Kava and St. John's wort (SJW) are the most commonly used herbal medicines in the treatment of anxiety and depressive disorders, respectively. OBJECTIVES The objective of this study was to conduct a comprehensive review of kava and SJW, to review any evidence of efficacy, mode of action, pharmacokinetics, safety and use in major depressive disorder, bipolar disorder, seasonal affective disorder (SAD), generalized anxiety disorder, social phobia (SP), panic disorder (PD), obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD). METHODS A systematic review was conducted using the electronic databases MEDLINE, CINAHL, and The Cochrane Library during late 2008. The search criteria involved mood and anxiety disorder search terms in combination with kava, Piper methysticum, kavalactones, St. John's wort, Hypericum perforatum, hypericin, and hyperforin. Additional search criteria for safety, pharmacodynamics, and pharmacokinetics were employed. A subsequent forward search was conducted of the papers using Web of Science cited reference search. RESULTS Current evidence supports the use of SJW in treating mild-moderate depression, and for kava in treatment of generalized anxiety. In respect to the other disorders, only weak preliminary evidence exists for use of SJW in SAD. Currently there is no published human trial on use of kava in affective disorders, or in OCD, PTSD, PD, or SP. These disorders constitute potential applications that warrant exploration. CONCLUSIONS Current evidence for herbal medicines in the treatment of depression and anxiety only supports the use of Hypericum perforatum for depression, and Piper methysticum for generalized anxiety.

Abstract
BACKGROUND Concern has been expressed about the relevance of secondary care studies to primary care patients specifically about the effectiveness of antidepressant medication. There is a need to review the evidence of only those studies that have been conducted comparing antidepressant efficacy with placebo in primary care-based samples. OBJECTIVES To determine the efficacy and tolerability of antidepressants in patients (under the age of 65 years) with depression in primary care. SEARCH STRATEGY All searches were conducted in September 2007.The Cochrane Depression, Anxiety and Neurosis Group (CCDAN) Controlled Trials Register was searched, together with a supplementary search of MEDLINE, PsycINFO, EMBASE, LILACS, CINAHL and PSYNDEX. Abstracts of all possible studies for inclusion were assessed independently by two reviewers. Further trials were sought through searching the reference lists of studies initially identified and by scrutinising other relevant review papers. Selected authors and experts were also contacted. SELECTION CRITERIA Studies were selected if they were randomised controlled trials of tricyclic antidepressants (TCAs) or selective serotonin reuptake inhibitors (SSRIs) versus placebo in adults. Older patients (over 65 years) were excluded. Patients had to be recruited from a primary care setting. For continuous outcomes the Hamilton Depression scale of the Montgomery Asberg Scale was requred. DATA COLLECTION AND ANALYSIS Data were extracted using data extraction forms by two reviewers independently, with disagreements resolved by discussion. A similar process was used for the validity assessment. Pooling of results was done using Review Manager 5. The primary outcome was depression reduction, based on a dichotomous measure of clinical response, using relative risk (RR), and on a continuous measure of depression symptoms, using the mean difference (MD), with 95% confidence intervals (CI). MAIN RESULTS There were fourteen studies (16 comparisons) with extractable data included in the review, of which ten studies examined TCAs, two examined SSRIs and two included both classes, all compared with placebo. The number of participants in the intervention groups was 1364 and in the placebo groups 919. Nearly all studies were of short duration, typically 6-8 weeks. Pooled estimates of efficacy data showed an RR of 1.24, 95% CI 1.11-1.38 in favour of TCAs against placebo. For SSRIs this was 1.28, 95% CI 1.15 to 1.43.. The numbers needed to treat (NNT) for TCAs ranged from 7 to 16 {median NNT 9} patient expected event rate ranged from 63% to 26% respectively) and for SSRIs from 7 to 8 {median NNT 7} (patient expected event rate ranged from 48% to 42% respectively) . The numbers needed to harm (NNH for withdrawal due to side effects) ranged from 4 to 30 for TCAs (excluding three studies with no harmful events leading to withdrawal) and 20 to 90 for SSRIs. AUTHORS' CONCLUSIONS Both TCAs and SSRIs are effective for depression treated in primary care.

Abstract
BACKGROUND Although pharmacological and psychological interventions are both effective for major depression, antidepressant drugs are frequently used as first-line treatment in primary and secondary care settings. Milnacipran, a dual serotonin-norepinephrine reuptake inhibitor (SNRI), is one of the antidepressant drugs that clinicians use for routine depression care. OBJECTIVES To assess the evidence for the efficacy, acceptability and tolerability of milnacipran in comparison with tricyclic antidepressants (TCAs), heterocyclics, SSRIs and other newer antidepressive agents in the acute-phase treatment of major depression. SEARCH STRATEGY The Cochrane Collaboration Depression, Anxiety & Neurosis review group Controlled Trials Register (CCDANCTR-Studies and CCDANCTR-References) were electronically searched in August 2008. References of relevant trials and other reviews were also checked. Trial databases of the drug-approving agencies and ongoing clinical trial registers for all published and unpublished trials were hand-searched in 2007. All relevant authors were contacted for supplemental data. No language restriction was applied. SELECTION CRITERIA Randomised controlled trials comparing milnacipran with any other active antidepressive agents (including non-conventional agents such as herbal products like hypericum) as monotherapy in the acute phase of major depression were selected. DATA COLLECTION AND ANALYSIS Two reviewers independently checked eligibility, assessed methodological quality and extracted data from the eligible trials using a standardised data extraction form. The number of participants who responded to treatment or those who achieved remission were calculated on an intention-to-treat basis. Random-effects meta-analyses were conducted, combining data from the included trials. MAIN RESULTS A total of 16 randomised controlled trials (n=2277) were included in the meta-analysis.Despite the size of this sample, the pooled 95% confidence intervals were rather wide and there were no statistically significant differences in efficacy, acceptability and tolerability when comparing milnacipran with other antidepressive agents. However, compared with TCAs, patients taking milnacipran were associated with fewer dropouts due to adverse events (OR 0.55; 95%CI 0.35 to 0.85). There was also some weak evidence to suggest that patients taking milnacipran experienced fewer adverse events of sleepiness/ drowsiness, dry mouth or constipation compared with TCAs. AUTHORS' CONCLUSIONS Currently, there is inadequate evidence to conclude whether milnacipran is superior, inferior or the same as other antidepressive agents in terms of efficacy, acceptability and tolerability in the acute phase treatment of major depression. However, there is some evidence in favour of milnacipran over TCAs in terms of dropouts due to adverse events (acceptability) and the rates of experiencing adverse events (tolerability). Information about other clinically meaningful outcomes such as cost-effectiveness and social functioning, including the ability to return to work, is lacking. Further study is needed to answer whether milnacipran would be the better choice of antidepressant for acute major depression.

Abstract
Fluvoxamine, one of the oldest selective serotonin reuptaking inhibitors, is commonly prescribed to patients with major depression. Several studies have reviewed the efficacy and tolerability of fluvoxamine for the treatment of major depression. However, these reviews are outdated, have not been systematic and/or suffered from several methodological weaknesses. We conducted a systematic review to synthesize the best available evidence on the efficacy of fluvoxamine for adult patients suffering from major depression in comparison with other active antidepressive agents. Relevant randomized controlled trials were identified through a comprehensive search. The primary outcome was a relative risk of response, and the secondary outcome was a relative risk of remission. Tolerability and side-effect profile were also examined. Fifty-three trials were included. There were no large differences between fluvoxamine and any other antidepressants in terms of efficacy and tolerability. There is evidence of differing side effect profiles, especially when comparing gastrointestinal side effects between fluvoxamine and tricyclics. Clinicians should focus on practically or clinically relevant differences including those in side-effect profiles.

Abstract
Despite adequate antidepressant monotherapy, the majority of depressed patients do not achieve remission. Even optimal and aggressive therapy leads to a substantial number of patients who show minimal and often only transient improvement. In order to address this substantial problem of treatment-resistant depression, a number of novel targets for antidepressant therapy have emerged as a consequence of major advances in the neurobiology of depression. Three major approaches to uncover novel therapeutic interventions are: first, optimizing the modulation of monoaminergic neurotransmission; second, developing medications that act upon neurotransmitter systems other than monoaminergic circuits; and third, using focal brain stimulation to directly modulate neuronal activity. We review the most recent data on novel therapeutic compounds and their antidepressant potential. These include triple monoamine reuptake inhibitors, atypical antipsychotic augmentation, and dopamine receptor agonists. Compounds affecting extra-monoamine neurotransmitter systems include CRF(1) receptor antagonists, glucocorticoid receptor antagonists, substance P receptor antagonists, NMDA receptor antagonists, nemifitide, omega-3 fatty acids, and melatonin receptor agonists. Focal brain stimulation therapies include vagus nerve stimulation (VNS), transcranial magnetic stimulation (TMS), magnetic seizure therapy (MST), transcranial direct current stimulation (tDCS), and deep brain stimulation (DBS).

Abstract
Genotyping patients prior to beginning psychiatric pharmacological therapy can serve to inform practitioners as to each patient's likelihood of therapeutic response and their relative risk of experiencing toxicity and other adverse side effects from certain drugs. Such information could arm physicians with the knowledge they need to make appropriate drug and dosing decisions and avoid the lengthy trial-and-error process with which they are faced today. This article describes the current state of pharmacogenetic testing in schizophrenia and posttraumatic stress disorder.

Abstract
Sertraline is a selective serotonin reuptake inhibitor that has been used and studied extensively throughout the world and found to be safe and well tolerated in numerous patient populations, including those with either psychiatric and/or medical comorbidities. Randomized clinical trials have shown that it is an effective treatment for depressive and anxiety disorders and its efficacy is unaffected by psychiatric comorbidity. In non-comorbid patients, sertraline is effective for the acute treatment of major depressive disorders and prevention of relapse or recurrence. It is effective for acute treatment and longer-term management of social anxiety disorder, posttraumatic stress disorder,panic disorder, and generalized anxiety disorder. In adults and in pediatric patients, it is an effective short-term and long-term treatment for obsessive compulsive disorder.Sertraline has a good tolerability profile and has low fatal toxicity. In summary, sertraline is as effective as other antidepressants over a wide range of indications but may offer tolerability benefits as well as efficacy in patients with psychiatric and/or medical comorbidities and certain subtypes of depression.

Abstract
The present contribution describes the history of the Cochrane review on St. John's wort (hypericum perforatum L.) for depression. Work for the first version started in 1993, the year that saw the official foundation of the Cochrane Collaboration, but 3 years before a pertinent Cochrane review group was established. After the registration of the Collaborative Review Group for Depression, Anxiety and Neuroses (CCDAN) and the publication of a first print version of the review that included 23 trials in 1996 the first Cochrane version with 27 trials became available in 1998. Updates were completed in 2005 (37 included trials) and 2008 (29 trials). Due to changes in selection criteria and review methods the resources needed to complete the 2005 and 2008 updates were similar to those for the first version in 1996. Only one trial included in the 1996 version is still part of the 2008 version. Despite the large number of available trials and improvements in review methodology the current evidence is more difficult to interpret than in 1996.

Abstract
Under heightened emotional states, individuals are more inclined to engage in ill-considered or rash actions than at other times. The authors present evidence for the existence of 2 related traits called positive and negative urgency. The traits refer to individual differences in the disposition to engage in rash action when experiencing extreme positive and negative affect, respectively. The authors provide evidence that these traits are distinct from other dispositions toward rash action and that they play distinct roles in predicting problem levels of involvement in behaviors such as alcohol consumption, binge eating, drug use, and risky sexual behavior. The authors identify facilitative conditions for the emergence of the urgency traits from neuroscience. Certain gene polymorphisms are associated with low levels of serotonin and high levels of dopamine; that pattern of neurotransmitter activity in a brain system linking the orbitofrontal cortex and the amygdala appears to facilitate the development of positive and negative urgency. The authors discuss the implications of this theory.

Abstract
PURPOSE To describe the diagnostic and treatment patterns for depression and anxiety in clients receiving care at a free clinic. DATA SOURCES Charts for 43 clients who received antidepressant or anxiolytic medications were randomly selected and reviewed. CONCLUSIONS Clients presented to the clinic symptomatic; almost two thirds had been treated elsewhere. Most clients received pharmacological treatment and referral for counseling. Forty-four percent of the clients were still being treated at their last visit, but 33% were no longer being seen, and it could not be determined if they were receiving care at another clinic. IMPLICATIONS FOR PRACTICE If sustained relationships with clients with depression and anxiety can be developed, appropriate care can be provided.

Abstract
Major depressive disorder (MDD) is a prevalent condition with substantial heterogeneity in terms of clinical symptom profiles, overlapping syndromes and degree of severity. The challenge for any new antidepressant is to demonstrate efficacy across the spectrum of patient subpopulations with a diagnosis of MDD. The anxious depressed patient historically has a lower rate of response to traditional antidepressants and high pretreatment anxiety symptoms have also been shown to increase the risk of recurrence. In addition, severity based on standard antidepressant rating scale scores influences treatment outcomes. Some antidepressants display greater placebo separation at higher levels of severity while others fail to separate from placebo in more severe populations. Gender differences in antidepressant response have also been reported in several studies. In particular, women appear to experience a greater side-effect burden with current antidepressants. This is also important in treating late-life depression, where elderly patients are more prone to experiencing side effects and drug interactions. Despite the improved tolerability with SSRIs and other novel antidepressants, restoration of healthy sleep patterns has frequently been lacking. Finally, antidepressant efficacy must include demonstrated relapse prevention during placebo-controlled drug discontinuation trials. As a novel antidepressant with melatonin receptor agonist and 5HT(2C) antagonist properties, agomelatine has demonstrated efficacy in randomized placebo-controlled trials. Additional analyses support the benefits of agomelatine in anxious depression, increasing efficacy with greater baseline severity, including severe late-life depression. Agomelatine has also demonstrated favourable tolerability and efficacy in separate analyses of women and men and displays successful relapse prevention at doses 25 and 50 mg. Both subjective and polysomnographic measures of sleep support increased sleep efficiency and decreased awakenings during agomelatine treatment. Combining these efficacy data with favourable effects on sexual function, CNS and GI systems, there are grounds to endorse the view that agomelatine is a well-tolerated and efficacious antidepressant for a diverse range of depressed populations.

Abstract
OBJECTIVES Recently, SOHO and CATIE's studies in the field of schizophrenic disorders asserted that molecules apparently showing the most side-effects are not only the most effective but also lead to the least changes in treatments. Can we generalise this assertion to other domains of pharmacological treatments, such as in mood and anxiety disorders? And, more generally, do we possess information about comparison between different types of molecules in these different fields. METHODS Review of the literature (medline-psycinfo-psycarticles) addressing these three psychiatric disorders, and comparing efficacy of treatments, or cost-effectiveness studies. RESULTS Although there is a plethora of publications about the efficacy of given molecules vs. placebo, studies comparing molecules are scarce, and studies on cost-effectiveness in natural environments are even more scarce. Independently of the type of disorders under study, the last few years' efforts to completely limit side effects seem to have resulted in a loss of efficacy. Moreover, the previously held hypothesis suggesting that the fewer the side effects, the lesser the need to change treatment has not been confirmed. The duration of a treatment is more dependent upon its efficacy than on other variables. CONCLUSIONS Clinicians cannot determine the absence of noxiousness of a molecule as their primary criterion of choice. In contrast, they should carefully balance side effects and efficacy. In Psychiatry, there is a lack of studies about cost-effectiveness in natural environments.

Abstract
This cross-sectional survey describes the clinical characteristics of 92 patients from across 12 general medical practices, in receipt of a long-term repeat prescription of an antidepressant for the treatment of depression. Psychiatric diagnoses were determined using the Schedule for Clinical Assessment in Neuropsychiatry. Fifty-three participants (57.6%) failed to meet criteria for any psychiatric diagnosis (95% confidence interval (CI): 47.5-67.7%). Independent clinical assessments based upon diagnoses and other clinical data indicated that 26 (31.0%) participants (95% CI: 28.9-49.7%) had no clear clinical reason for continued receipt of an antidepressant. Reasons for the continued use of antidepressants in this population require further investigation.

Abstract
A revision of the 2000 British Association for Psychopharmacology evidence-based guidelines for treating depressive disorders with antidepressants was undertaken to incorporate new evidence and to update the recommendations where appropriate. A consensus meeting involving experts in depressive disorders and their management was held in May 2006. Key areas in treating depression were reviewed, and the strength of evidence and clinical implications were considered. The guidelines were drawn up after extensive feedback from participants and interested parties. A literature review is provided, which identifies the quality of evidence to inform the recommendations, the strength of which are based on the level of evidence. These guidelines cover the nature and detection of depressive disorders, acute treatment with antidepressant drugs, choice of drug versus alternative treatment, practical issues in prescribing and management, next-step treatment, relapse prevention, treatment of relapse, and stopping treatment.

Abstract
Depression is a common accompaniment of pain, particularly when pain is unremitting. The use of a variety of antidepressant medications is associated with pain reduction, an effect that is independent of the mood-enhancing qualities of these drugs. This pain relief is a consequence of a wide variety of actions of antidepressants on the neuroregulatory mechanisms associated with pain perception and transmission. The older tricyclic antidepressants (TCAs) and the newer 'balanced' reuptake inhibitors (such as duloxetine) seem to be more efficacious in terms of providing pain relief than the selective serotonin reuptake inhibitors (SSRIs). Unfortunately, adverse effects are not uncommon during antidepressant use, particularly with TCAs. It is now becoming apparent that TCAs can have an analgesic effect when applied topically and that this effect is produced by peripheral mechanisms rather than systemic uptake. Antidepressants remain a major therapeutic tool in the management of chronic pain.

Abstract
OBJECTIVES Post-stroke depression (PSD) is prevalent, often undiagnosed, and undertreated. The accuracy of detecting patients with post-stroke depression in administrative databases has not been examined.The objective was to validate a case-finding algorithm for post-stroke depression (PSD) among veteran stroke survivors. METHODS We conducted a retrospective cohort study of veterans admitted to two local VHA facilities for an inpatient episode of care for acute ischemic stroke. Our cohort included all patients from two medical centers who were identified in the fiscal year (FY) 2001 VHA inpatient database using high specificity stroke ICD-9 codes. FY 2002 VHA and Medicare inpatient, outpatient, and pharmacy data were used to examine the patients' 12-month PSD status by using ICD-9 depression codes and antidepressant use. We assessed our accuracy about patients' PSD from the administrative databases through standardized chart reviews. RESULTS Of our 185 subject cohort, 50 (27%) were identified as having PSD. The most sensitive case-finding algorithm for PSD included having an ICD-9 code diagnosis for depression or receiving a prescription for an approved-dosage of antidepressant medication. However, the algorithm of receiving an ICD-9 code for primary or secondary diagnoses of depression revealed the largest positive predictive value. CONCLUSIONS A case-finding algorithm using outpatient ICD-9 codes or medication was the most sensitive in identifying cases of PSD. The use of ICD-9 codes alone may be adequate for characterizing a cohort with PSD. Intention for use should be considered when choosing an algorithm to detect PSD.

Abstract
Antidepressant prescribing patterns and factors influencing the choice of antidepressant for the treatment of depression were examined in the Factors Influencing Depression Endpoints Research (FINDER) study, a prospective, observational study in 12 European countries of 3468 adults about to start antidepressant medication for their first episode of depression or a new episode of recurrent depression. Selective serotonin reuptake inhibitors (SSRIs) were the most commonly prescribed antidepressant (63.3% patients), followed by serotonin-norepinephrine reuptake inhibitors (SNRIs, 13.6%), but there was considerable variation across countries. Notably, tricyclic and tetracyclic antidepressants (TCAs) were prescribed for 26.5% patients in Germany. The choice of the antidepressant prescribed was strongly influenced by the previous use of antidepressants, which was significantly associated with the prescription of a SSRI (OR 0.64; 95% CI 0.54, 0.76), a SNRI (OR 1.49; 95% CI 1.18, 1.88) or a combination of antidepressants (OR 2.78; 95% CI 1.96, 3.96). Physician factors (age, gender, speciality) and patient factors (severity of depression, age, education, smoking, number of current physical conditions and functional syndromes) were associated with initial antidepressant choice in some models. In conclusion, the prescribing of antidepressants varies by country, and the type of antidepressant chosen is influenced by physician- as well as patient-related factors.

Abstract
OBJECTIVE To estimate the costs and quality-adjusted life weeks of duloxetine and escitalopram. RESEARCH DESIGN A probabilistic Markov cost-utility analysis with a time horizon of 1 year using data from placebo controlled randomized clinical trials for both products. METHODS Efficacy was defined as remission of depressive symptoms and converted to utilities. Side effects were incorporated using rates from clinical trials and converted to utilities to define treatment effectiveness. The effectiveness outcome was quality adjusted life weeks (QALWs). Estimates of effectiveness (efficacy and side effects) used beta distributions and costs used gamma distributions. Using a managed care perspective, medication costs and physician office visits were included in the model, along with costs associated with treatment failure. Antidepressant costs were obtained using average wholesale price minus 20%. Physician visit costs were obtained from the 2006 US Medicare fee schedule for physician services. A Monte Carlo simulation was conducted using 1000 trials with both first- and second-order sampling. RESULTS Over 1 year, the estimated mean quality-adjusted life weeks was 41.0 (95% confidence interval [CI]: 40.7-41.3) for escitalopram and 38.2 (95% CI: 37.9-38.4) for duloxetine. The mean annual total medical cost for escitalopram was $907 (95% CI: $894-$919) and $1633 (95% CI: $1614-$1654) for duloxetine. Limitations to this analysis include using separate studies examining the efficacy and adverse events of either escitalopram or duloxetine, assuming the switch, augmentation, and titration rates for duloxetine to be similar to escitalopram, and using utility estimates from published literature for the antidepressant adverse events. CONCLUSION This analysis suggests that escitalopram was more effective in terms of QALWs and less costly than duloxetine for treatment of depression.

Abstract
The regulation of bone metabolism continues to be an area of intense investigation, with recent evidence indicating a potential contribution from the neural system. In particular, the neurotransmitter serotonin (5-hydroxytryptamine [5-HT]) has been hypothesized to play a role in skeletal metabolism via its transporter (5-HTT). The 5-HTT is a plasma membrane transporter that is highly specific for the uptake of extracellular 5-HT, thereby facilitating the intracellular storage and/or degradation of 5-HT. The 5-HTT is clinically important as it is the key target of pharmaceutical agents aimed at treating affective disorders, such as major depressive disorder. By antagonizing the 5-HTT, selective serotonin reuptake inhibitors (SSRIs) potentiate 5-HT activity and effectively relieve the symptoms of depression. However, questions have been raised regarding the potential skeletal effects of SSRIs given the recent identification of a functional 5-HTT and functional 5-HT receptors in bone cells. This paper discusses the preclinical evidence for the skeletal effects of 5-HT and the inhibition of the 5-HTT. In particular, it discusses the: (1) role of 5-HT and the function of the 5-HTT; (2) presence of functional 5-HTTs in bone; (3) potential sources and response mechanisms for 5-HT in bone, and; (4) in vitro and in vivo skeletal effects of 5-HT and 5-HTT inhibition.

Abstract
OBJECTIVE To compare therapeutic effects of eicosapentaenoic acid (EPA), fluoxetine and a combination of them in major depression. METHOD Sixty outpatients with a diagnosis of major depressive disorder based on DSM-IV criteria and a score >or=15 in the 17-item Hamilton Depression Rating Scale (HDRS) were randomly allocated to receive daily either 1000 mg EPA or 20 mg fluoxetine, or their combination for 8 weeks. Double dummy technique was used to double blind the study. Patients were assessed at 2 week intervals. Change in HDRS was the primary outcome measure. RESULTS Analysis of covariance for HDRS at week 8 across treatment groups was performed in 48 patients who completed at least 4 weeks of the study, with the last observation carried forward. Treatment, age of onset and baseline HDRS had a significant effect on HDRS at week 8. EPA + fluoxetine combination was significantly better than fluoxetine or EPA alone from the fourth week of treatment. Fluoxetine and EPA appear to be equally effective in controlling depressive symptoms. Response rates (>or=50% decrease in baseline HDRS) were 50%, 56% and 81% in the fluoxetine, EPA and combination groups, respectively. CONCLUSIONS In the present 8 week trial EPA and fluoxetine had equal therapeutic effects in major depressive disorder. EPA + fluoxetine combination was superior to either of them alone.

Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) have been associated with upper gastrointestinal haemorrhage (UGIH) but the magnitude and characteristics of this reaction and possible interaction with concurrent Non-Steroidal Anti-Inflammatory Drug (NSAID) therapy are unknown. AIM To evaluate systematically the risk of UGIH with SSRIs, including interaction with NSAIDs. METHODS We searched PubMED, Science Citation Index, and trial registries for data on SSRIs, NSAIDs and UGIH. We evaluated spontaneous case reports from pharmacovigilance databases. RESULTS Random effects meta-analysis of four observational studies involving 153 000 patients showed an odds ratio of 2.36 (95% CI: 1.44-3.85; P = 0.0006) for SSRI associated UGIH. The odds ratio increased to 6.33 (95% CI: 3.40-11.8; P < 0.00001) with concomitant NSAIDs. In patients aged above 50 years with no UGIH risk factors, the Number-Needed-to-Harm per year is 411 for SSRIs alone, and 106 with concomitant NSAIDs. Analysis of 101 spontaneous reports showed that UGIH occurred after a median of 25 weeks with SSRIs. Around 67% of these patients were on NSAIDs. CONCLUSIONS Selective serotonin reuptake inhibitor use, alone and in combination with NSAIDs, substantially increases the risk of UGIH. Clinicians should consider this when managing patients at risk of, or presenting with UGIH.

Abstract
OBJECTIVE Depression often goes undetected and untreated in patients with chronic heart failure (CHF). To investigate whether patients with CHF show a specific profile of depression symptoms, we compared depression symptoms in depressed patients with and without CHF. METHODS Of a total of 921 patients from a CHF and a psychosomatic outpatient clinic, 137 met DSM-IV diagnostic criteria for major depressive disorder and 113 for other depressive disorders. Depressed patients with CHF (n=113) and without CHF (n=137) were compared with respect to severity of individual DSM-IV depressive symptoms, as measured with the PHQ-9. To stratify for depression severity, ANCOVAs with sociodemographic characteristics as covariates were performed separately for patients with major depressive disorder and other depressive disorders. RESULTS Among the patients meeting the criteria for major depressive disorder, patients with CHF reported significantly lower levels of depressed mood (p=.006) and worthlessness/guilt (p=.019) than patients without CHF. In contrast, no significant group differences were found for any of the other depression symptoms. Group comparisons among the patients with other depressive disorders completely replicated these results (p< or =.001, and p=.04, respectively). LIMITATIONS Our study population of CHF patients may not be representative for CHF patients recruited in the general population. CONCLUSIONS The diagnostic features discriminating between depressed patients with and without CHF are the cognitive-emotional symptoms of depression, not the somatic symptoms. This finding may partially explain the low recognition rate of depression in patients with CHF. The different profile of depression symptoms in patients with and without CHF should be considered in diagnosis, treatment and medical education.

To evaluate the efficacy of selective serotonin reuptake inhibitors (SSRIs) in children and adolescents with depressive disorder, the main electronic databases and the reference lists of retrieved articles and reviews were searched up to January 2007. Randomized controlled studies (RCT) were assessed for methodological quality, taking into consideration the specific diagnostic and severity evaluation tools used, and a meta-analysis on the efficacy of SSRIs compared placebo was undertaken. In all, 13 studies were included, covering a total of 2530 children and adolescents. Eleven studies met the criteria for inclusion in the meta-analysis. The pooled odds ratio was 1.57 (95% C.I. 1.29-1.91). Only fluoxetine appeared to offer a moderately significant benefit profile (OR=2.39). All studies differed in diagnostic tools and primary efficacy measures. SSRI treatment, especially with fluoxetine, may be effective on child and adolescent depression. Nevertheless, additional RCTs with sound methodological designs, validated diagnostic instruments, large sample sizes, and consistent outcomes are necessary to determine the role of SSRIs, alone or in combination with psychological interventions in the treatment of depression in children and adolescents.

Abstract
The proportion of diagnosed depressives prescribed antidepressants has increased markedly over the last 20 years, mainly following the introduction of the selective serotonin reuptake inhibitors. However, currently available antidepressants have notable limitations, relating to their only moderate efficacy relative to placebo, relatively slow onset of action, possible withdrawal symptoms, and problems of compliance. Sleep disturbances are often used to identify newly presenting depressive patients, and may be part of a more general alteration of bodily rhythms. There are links between pharmacological treatments and circadian rhythms in depression, which might represent another, new option for the development of a therapeutic approach to depression treatment. Many antidepressants affect sleep, some are sedative, and others have been used specifically in severely insomniac depressives. Disturbances in circadian rhythms may be an integral part of depressive mechanisms, and normalising them via an innovative mechanism of antidepressant action may be a fruitful avenue in the search for improved antidepressant agents.

Abstract
The long-term relationship that optometrists have with their patients enables them to note changes in affect, behavior, and functioning that could indicate serious mental illness, including clinical depression. Given the significant disability associated with this disease and the increased risk of suicide, appropriate management is critical. This article reviews the diagnosis and treatment of clinical depression and its appropriate referral.

Abstract
OBJECTIVES To examine the available scientific literature for answers to clinically relevant questions regarding the effectiveness and tolerability of antidepressant drugs (ADs) for the acute phase treatment of depression and to assess the degree to which the literature supports the findings. METHODS We used several sources to identify primary reviews: MEDLINE (1955 to April 2006), EMBASE (1980 to April 2006), PsycINFO (1980 to April 2006), and the Cochrane Library 2006 Issue 1. Additional searches were also carried out on the following databases of the National Health Service Centre for Reviews and Dissemination: Abstracts of Reviews of Effects, Health Technology Assessment, and Turning Research into Practice. We also searched the National Institute of Health and Clinical Excellence guidance website. We carried out a metareview of selected high-quality systematic reviews of short-term pharmacologic interventions with ADs for major depression. To assess efficacy, we followed the hierarchy of evidence proposed by the Centre for Evidence Based Medicine (Oxford), including only reviews of randomized controlled trials. To assess tolerability, we also considered observational data when randomized evidence was not available. RESULTS There was randomized evidence that ADs are efficacious in primary care settings and that there may be small, but clinically important, differences in efficacy between ADs. There was no good evidence that an AD combined with an antipsychotic is superior to AD monotherapy in cases of psychotic depression or that intravenous administration leads to more rapid response. There was evidence that monoamine oxidase inhibitors are superior to tricyclic antidepressants, but not to selective serotonin reuptake inhibitors (SSRIs), in treating atypical depression. There is some evidence of harm related to the use of SSRIs in pregnancy but not to their use when breastfeeding. There is evidence that SSRIs may increase suicidal thoughts, but not actual suicide, in early-phase therapy. CONCLUSIONS We found a substantial body of evidence regarding the benefits and harms of ADs in the treatment of depressive disorder. Nonetheless, there remains considerable residual uncertainty. The evidence is inadequate for generally applicable recommendations; in most cases, the balance between risks and benefits will need to be considered for individual patients. Clinicians should also be guided by the recommendations and warnings issued by drug regulatory authorities.

Abstract
BACKGROUND More than 40% of people born with cystic fibrosis (CF) now reach adulthood. Greater attention is being focused on improving their health-related quality of life (HRQoL). While markers of disease severity such as lung function are only modestly associated with HRQoL, in other chronic illnesses depression is an important correlate. The objective of this study was to evaluate the relationships among lung function (ie, FEV(1) percent predicted), depressive symptoms, and HRQoL among adults with CF. METHODS Seventy-six adults with CF completed a mail-based survey. The Beck Depression Inventory and the Cystic Fibrosis Questionnaire were used to assess depressive symptoms and HRQoL, respectively. Values for FEV(1) percent predicted were abstracted from the medical record. RESULTS Thirty percent of participants screened positive for depressive symptoms. Depressive symptoms and lung function were inversely correlated (rho = -0.25; p < .05). Correlations between depressive symptoms and HRQoL were maintained after stratifying by lung function. In the absence of depressive symptoms, those patients with good lung function (ie, FEV(1), > 70% predicted) reported better physical HRQoL than those with poor lung function. Participants with both depressive symptoms and poor lung function reported significantly worse HRQoL on all domains than participants without depressive symptoms regardless of lung function status. CONCLUSIONS Depressive symptoms are prevalent among adults with CF and are associated with poorer HRQoL even after controlling for lung function. These results suggest that screening for and treating depression is important and may potentially improve HRQoL among patients with CF.

Abstract
INTRODUCTION Depression may affect up to 10% of the population, with half of affected people having recurrence of their symptoms. In mild to moderate depression, there is no reliable evidence that any one treatment is superior in improving symptoms of depression, but the strength of evidence supporting different treatments varies. In severe depression, only prescription antidepressants and electroconvulsive therapy are known to improve symptoms. METHODS AND OBJECTIVES We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments in mild to moderate and severe depression, and in treatment-resistant depression? Which interventions reduce relapse rates? We searched: Medline, Embase, The Cochrane Library and other important databases up to April 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS We found 87 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS In this systematic review we present information relating to the effectiveness and safety of the following interventions: antidepressant drugs (tricyclic antidepressants [including low-dose tricyclic antidepressants], selective serotonin reuptake inhibitors, monoamine oxidase inhibitors, reboxetine, or venlafaxine), continuing prescription antidepressant drugs, electroconvulsive therapy, exercise, lithium augmentation, pindolol augmentation, St John's Wort.

Abstract
Primary care settings are the principal context for treating clinical depression, with researchers beginning to explore the efficacy of psychosocial and pharmacological treatments for depression within this infrastructure. Feasibility and process variables also are being assessed, including issues of cost-effectiveness, viability of collaborative care models, predictors of treatment outcome, and effectiveness of treatment providers without specialized mental health training. The Agency for Health Care Policy and Research and American Psychiatric Association initially released guidelines for the treatment of depression in primary care [American Psychiatric Association, 1993. Practice Guidelines for major depressive disorder in adults. American Journal of Psychiatry, 150, 1-26., American Psychiatric Association, 2000. Practice Guideline for the treatment of patients with major depressive disorder (revision). American Journal of Psychiatry, 157, 1-45], however, a vast literature has accumulated over the past several years, calling for a systematic re-evaluation of the status of depression treatment in primary care. The present study provides a contemporary review of outcome data for psychosocial and pharmacological interventions in primary care and extends beyond AHCPR guidelines insofar as focusing on feasibility and process variables, including the training and proficiency of primary care treatment providers, cost-effectiveness of primary care interventions, and predictors of treatment response and relapse. Based on current guidelines, problem-solving therapy (PST-PC), interpersonal psychotherapy, and pharmacotherapy would be considered efficacious interventions for major depression, with cognitive-behavioral and cognitive therapy considered possibly efficacious. Psychotherapy and pharmacotherapy generally are of comparable efficacy, and both modalities are superior to usual care in treating depression. Methodological limitations and directions for future research are discussed.

Abstract
More than half of gastric bypass patients take antidepressants preoperatively, presenting some unique considerations with this patient population. The challenges associated with antidepressant medications are experienced both preoperatively and postoperatively. As the gastric bypass option becomes more readily used in the treatment of obesity, the requirement for understanding the effect of this procedure on any alteration of medications will become more clinically important. The purpose of this paper is to present an overview of the potential challenges in providing optimal patient care for the gastric bypass patient who is taking antidepressant medications.

Abstract
BACKGROUND Depressive disorder is currently one of the most burdensome disorders worldwide. Evidence-based treatments for depressive disorder are already available, but these are used insufficiently, and with less positive results than possible. Earlier research in the USA has shown good results in the treatment of depressive disorder based on a collaborative care approach with Problem Solving Treatment and an antidepressant treatment algorithm, and research in the UK has also shown good results with Problem Solving Treatment. These treatment strategies may also work very well in the Netherlands too, even though health care systems differ between countries. METHODS/DESIGN This study is a two-armed randomised clinical trial, with randomization on patient-level. The aim of the trial is to evaluate the treatment of depressive disorder in primary care in the Netherlands by means of an adapted collaborative care framework, including contracting and adherence-improving strategies, combined with Problem Solving Treatment and antidepressant medication according to a treatment algorithm. Forty general practices will be randomised to either the intervention group or the control group. Included will be patients who are diagnosed with moderate to severe depression, based on DSM-IV criteria, and stratified according to comorbid chronic physical illness. Patients in the intervention group will receive treatment based on the collaborative care approach, and patients in the control group will receive care as usual. Baseline measurements and follow up measures (3, 6, 9 and 12 months) are assessed using questionnaires and an interview. The primary outcome measure is severity of depressive symptoms, according to the PHQ9. Secondary outcome measures are remission as measured with the PHQ9 and the IDS-SR, and cost-effectiveness measured with the TiC-P, the EQ-5D and the SF-36. DISCUSSION In this study, an American model to enhance care for patients with a depressive disorder, the collaborative care model, will be evaluated for effectiveness in the primary care setting. If effective across the Atlantic and across different health care systems, it is also likely to be an effective strategy to implement in the treatment of major depressive disorder in the Netherlands.

Abstract
During the past 10 years our knowledge about the pharmacotherapy of depression has been consolidated, and a variety of very interesting new compounds launched onto the market. The pipeline of the pharmaceutical industry is still filled with an assortment of new developments and very promising new approaches towards the pharmacotherapy of depressive disorders. Future pharmacological treatments of depression will not only enhance serotonergic and noradrenergic neurotransmission: other systems, such as the melatonergic receptor system and the hypothalamus-pituitary-adrenal axis, are also the targets of newly developed and upcoming substances with putative antidepressant effects. The main advantages of the currently available newer pharmacotherapeutic options are the broadening of the spectrum of possible antidepressant treatments, which is of particular importance for the growing number of patients suffering from difficult-to-treat depression, and a far better tolerability profile in comparison to older compounds such as tricyclic antidepressants. Unresolved issues are the unacceptably high rate of non-responsiveness during antidepressant treatment, a latency of sometimes several weeks until clinical improvement and remission can be achieved, and a variety of possible side effects also present during treatment with modern compounds. This review mainly presents the development of antidepressant pharmacotherapies during the past 10 years, together with pharmacokinetic and pharmacodynamic information and a comparison of different pharmacological treatment principles evaluated in randomized controlled clinical trials. In addition, new pharmacological strategies that are not yet available on the market and strategies currently under development are reviewed in detail. The study of new treatment options is of major importance to provide better strategies for the clinical management of depression in the future, and is thus also of great socio-economic importance.

Abstract
OBJECTIVE To assess whether patients receiving aerobic exercise training performed either at home or in a supervised group setting achieve reductions in depression comparable to standard antidepressant medication (sertraline) and greater reductions in depression compared to placebo controls. METHODS Between October 2000 and November 2005, we performed a prospective, randomized controlled trial (SMILE study) with allocation concealment and blinded outcome assessment in a tertiary care teaching hospital. A total of 202 adults (153 women; 49 men) diagnosed with major depression were assigned randomly to one of four conditions: supervised exercise in a group setting; home-based exercise; antidepressant medication (sertraline, 50-200 mg daily); or placebo pill for 16 weeks. Patients underwent the structured clinical interview for depression and completed the Hamilton Depression Rating Scale (HAM-D). RESULTS After 4 months of treatment, 41% of the participants achieved remission, defined as no longer meeting the criteria for major depressive disorder (MDD) and a HAM-D score of <8. Patients receiving active treatments tended to have higher remission rates than the placebo controls: supervised exercise = 45%; home-based exercise = 40%; medication = 47%; placebo = 31% (p = .057). All treatment groups had lower HAM-D scores after treatment; scores for the active treatment groups were not significantly different from the placebo group (p = .23). CONCLUSIONS The efficacy of exercise in patients seems generally comparable with patients receiving antidepressant medication and both tend to be better than the placebo in patients with MDD. Placebo response rates were high, suggesting that a considerable portion of the therapeutic response is determined by patient expectations, ongoing symptom monitoring, attention, and other nonspecific factors.

Abstract
Established treatments for depression are often effective. However, a significant number of patients show limited or no response. With advancements in the explanation of the underlying neurobiology of depression, several novel therapeutic approaches have been developed. Emerging drug targets include novel monoamine oxidase inhibitors, triple monoamine re-uptake inhibitors, omega-3 fatty acids, melatoninergic agonists and receptor antagonists for corticotropin-releasing factor(1), glucocorticoid, substance-P and NMDA. Developments in therapeutic focal brain stimulation include vagus nerve stimulation, transcranial magnetic stimulation, magnetic seizure therapy and deep brain stimulation. The role of psychotherapy, both as monotherapy and as adjunctive therapy, is an active avenue of investigation. Although data on these treatments are limited, preliminary results are encouraging. A major goal that remains to be achieved is the identification of predictors of response to the various antidepressant treatments that have diverse mechanisms of action.

Abstract
Background General Practitioners (GPs) in Thailand play an important role in treating psychiatric disorders since there is a shortage of psychiatrists in the country. Our aim was to examine GP's perception of psychiatric problems, drug treatment and service problems encountered in primary care settings. Methods We distributed 1,193 postal questionnaires inquiring about psychiatric practices and service problems to doctors in primary care settings throughout Thailand. Results Four hundred and thirty-four questionnaires (36.4%) were returned. Sixty-seven of the respondents (15.4%) who had taken further special training in various fields were excluded from the analysis, giving a total of 367 GPs in this study. Fifty-six per cent of respondents were males and they had worked for 4.6 years on average (median = 3 years). 65.6% (SD = 19.3) of the total patients examined had physical problems, 10.7% (SD = 7.9) had psychiatric problems and 23.9% (SD = 16.0) had both problems. The most common psychiatric diagnoses were anxiety disorders (37.5%), alcohol and drugs abuse (28.1%), and depressive disorders (29.2%). Commonly prescribed psychotropic drugs were anxiolytics and antidepressants. The psychotropic drugs most frequently prescribed were diazepam among anti-anxiety drugs, amitriptyline among antidepressant drugs, and haloperidol among antipsychotic drugs. Conclusion Most drugs available through primary care were the same as what existed 3 decades ago. There should be adequate supply of new and appropriate psychotropic drugs in primary care. Case-finding instruments for common mental disorders might be helpful for GPs whose quality of practice was limited by large numbers of patients. However, the service delivery system should be modified in order to maintain successful care for a large number of psychiatric patients.
