Abstract
OBJECTIVE Major depressive disorder (MDD) and chronic pain are highly comorbid and bidirectionally related. Repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex is effective in treating MDD, but additional research is needed to determine if chronic pain interferes with rTMS for MDD. METHODS Participants were 124 veterans ( Mage = 49.14, SD = 13.83) scheduled for 30 sessions of rTMS across 6 weeks. Depression severity was monitored weekly using the Patient Health Questionnaire-9 (PHQ-9). Having any pain diagnosis, low back pain, or headache/migraine were assessed by chart review. We fit latent basis models to estimate total change by pain diagnosis in depression scores and quadratic latent growth models to examine differences in growth rates. Then, we computed χ2 tests of group differences in response (PHQ-9 reduction ≥50%) and remission rates (final PHQ-9 < 5). RESULTS A total of 92 participants (74%) had a documented pain diagnosis, 58 (47%) had low back pain, and 32 (26%) had headache/migraine. In growth models, depression scores initially decreased (linear slope estimate = -2.04, SE = 0.26, p < .0001), but the rate of decrease slowed over time (quadratic slope estimate = 0.18, SE = 0.04, p < .001). Overall change was not different as a function of any pain diagnosis ( p = .42), low back pain (p = .11 ), or headache/migraine ( p = .28). However, we found that low back pain was a negative predictor of response ( p = .032). CONCLUSIONS These data support rTMS as a viable treatment option for comorbid populations. Although patients with comorbid chronic pain conditions are likely to receive benefit from rTMS for depression, adjunctive pain treatment may be indicated.

Associations between somatic symptoms and remission of major depressive disorder: A longitudinal study in China. J Psychiatr Res 2024; 172:382-390. [PMID: 38452636 DOI: 10.1016/j.jpsychires.2024.02.056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 02/17/2024] [Accepted: 02/24/2024] [Indexed: 03/09/2024]
Abstract
Previous studies have documented negative associations between somatic symptoms and remission of major depressive disorder (MDD). However, the correlations of specific somatic symptoms with remission remain uncertain. We aimed to explore the associations between specific somatic symptoms and remission focusing on sex differences among patients with MDD. We used data from patients with MDD in the Depression Cohort in China. At baseline, total somatic symptoms were evaluated using the 28-item Somatic Symptoms Inventory and were categorized into pain, autonomic, energy, and central nervous system (CNS) symptoms. To measure remission of MDD, depressive symptoms were evaluated using the Patient Health Questionnaire-9 after 3 months of treatment. We ultimately included 634 patients. Compared with quartile 1 of total somatic symptom scores, the full-adjusted ORs (95% CIs) for remission from quartile 2 to quartile 4 were 0.52 (0.30, 0.90), 0.44 (0.23, 0.83), and 0.36 (0.17, 0.75), respectively (P-value for trend = 0.005). The restricted cubic spline showed no non-linear associations between total somatic symptoms with remission (P-value for non-linear = 0.238). Pain, autonomic, and CNS symptoms showed similar results. Sex-stratified analysis showed that total somatic symptoms, pain symptoms, and autonomic symptoms were negatively correlated with remission in females, whereas CNS symptoms were negatively associated with remission in males. Our findings indicate that specific somatic symptoms exert differential effects on remission of MDD. Therapeutic interventions that target pain, autonomic, and CNS symptoms may increase the probability of remission. Furthermore, interventions for somatic symptoms should be tailored by sex, and females deserve more attention.

Abstract
It has recently been recommended that treatment resistant depression be reconceptualized and renamed as difficult to treat depression (DTD). A consensus statement by an expert panel identified multiple variables associated with DTD and emphasized the importance of conducting a comprehensive evaluation of patients to identify predictors of inadequate treatment response. For practical reasons, it would be desirable to develop a self-report scale that can be incorporated into clinical practice that identifies patient, clinical, and treatment risk factors for DTD. Nine hundred twenty depressed patients completed the Difficult to Treat Depression Questionnaire (DTDQ). A subset of patients completed the scale a second time and completed the Remission from Depression Questionnaire at admission and discharge from a partial hospital program. The DTDQ demonstrated excellent internal consistency and test-retest reliability. Both the total DTDQ and the number of prior failed medication trials, the metric primarily relied upon to classify treatment resistant depression, predicted outcome. However, the DTDQ continued to be significantly associated with outcome after controlling for the number of failed trials, whereas the number of failed trials did not predict outcome after controlling for DTDQ scores. The DTDQ is a reliable and valid measure of the recently discussed concept of DTD.

Abstract
BACKGROUND The presence of heterogenous somatic symptoms frequently obscures the recognition of depression in primary care. We aimed to explore the association between somatic symptoms and subthreshold depression (SD) and Major Depressive Disorder (MDD), as well as to determine the predictive potential of somatic symptoms in identifying SD and MDD in primary care. METHODS Data were derived from the Depression Cohort in China study (ChiCTR registry number: 1900022145). The Patient Health Questionnaire-9 (PHQ-9) was used to assess SD by trained general practitioners (GPs), and the Mini International Neuropsychiatric Interview depression module was used to diagnose MDD by professional psychiatrists. Somatic symptoms were assessed using the 28-item Somatic Symptoms Inventory (SSI). RESULTS In total of 4,139 participants aged 18-64 years recruited from 34 primary health care settings were included. The prevalence of all 28 somatic symptoms increased in a dose-dependent manner from non-depressed controls to SD, and to MDD (P for trend <0.001). Hierarchical clustering analysis grouped the 28 heterogeneous somatic symptoms into three clusters (Cluster 1: energy-related symptoms, Cluster 2: vegetative symptoms, and Cluster 3: muscle, joint, and central nervous symptoms). Following adjustment for potential confounders and the other two clusters of symptoms, per 1 increase of energy-related symptoms exhibited significant association with SD (OR = 1.24, 95% CI, 1.18-1.31) and MDD (OR = 1.50, 95% CI, 1.41-1.60) The predictive performance of energy-related symptoms in identifying individuals with SD (AUC = 0.715, 95% CI, 0.697-0.732) and MDD (AUC = 0.941, 95% CI, 0.926-0.963) was superior to the performance of total SSI and the other two clusters (P < 0.05). CONCLUSIONS Somatic symptoms were associated with the presence of SD and MDD. In addition, somatic symptoms, notably those related to energy, showed good predictive potential in identifying SD and MDD in primary care. The clinical implication of the present study is that GPs should consider the closely related somatic symptoms for early recognition for depression in practice.

Abstract
INTRODUCTION Due to the complexity of symptoms in major depressive disorder (MDD), the majority of depression scales fall short of accurately assessing a patient's progress. When selecting the most appropriate antidepressant treatment in MDD, a multidimensional scale such as the Hamilton Depression Rating scale (HAM-D) may provide clinicians with more information especially when coupled with unidimensional analysis of some key factors such as depressed mood, altered sleep, psychic and somatic anxiety and suicidal ideation etc. METHODS HAM-D measurements were carried out in patients with MDD when treated with two different therapeutic interventions. The prespecified primary efficacy variables for the study were changes in score from baseline to the end of the 12 weeks on HAM-D scale (i.e., ≤ 8 or ≥50% response). The study involved three assessment points (baseline, 6 weeks and 12 weeks). RESULTS Evaluation of both the absolute HAM-D scores and four factors derived from the HAM-D (depressed mood, sleep, psychic and somatic anxiety and suicidal ideation) revealed that the latter showed a greater promise in gauging the anti-depressant responses. CONCLUSION The study confirms the assumption that while both drugs may improve several items on the HAM-D scale, the overall protocol may fall short of addressing the symptoms diversity in MDD and thus the analysis of factor (s) in question might be more relevant and meaningful.

Abstract
OBJECTIVE Major depressive disorder is the leading cause of non-fatal burden, and disability in adulthood. Even though depression is well-treated in the acute term,psychosocial functioning does not get back to the premorbid level most of the time. In this present study, it is aimed to evaluate the outcome of the acute term treatment of major depressive disorder in terms of psychosocial functioning. METHODS The study is an open-label, observational, multi-center follow-up study for four months of patients with major depressive disorder according to DSM-5. Patients were evaluated with Montgomery Asberg Depression Rating Scale (MADRS), Sheehan Disability Scale (SDS) and Short Form-36 (SF-36) at the beginning, and at the 2., 4., 8., 12. and 16.weeks. RESULTS 100 patients were invited to the study and 56 patients completed the study.As a result of the treatment, the mean MADRS and SDS scores decreased significantly. All domains of SF-36 were improved significantly with the treatment. Unfortunately patients suffering from MDD could not reach the normative data,especially on the domains of social functioning, role emotional, pain, and general health perception. Treatment outcomes show that SNRI users presented higher scores on the domains of pain and physical functioning. However SSRI users showed better outcomes on the domains of mental health and vitality. CONCLUSION Our research corroborated that even patients gain symptomatic remission in MDD treatment, psychosocial dysfunction persists. It is also concluded that different antidepressant options may act differently on treatment outcomes.

Abstract
Background Major depressive disorder (MDD) is associated with decreased patient well-being and symptoms that can cause substantial impairments in patient functioning and even lead to suicide. Worldwide, MDD currently causes the second-most years lived with disability and is predicted to become the leading cause of disability by 2030. Utility values, capturing patient quality of life, are required in economic evaluations for new treatments undergoing reimbursement submissions. We aimed to identify health state utility values (HSUVs) and disutilities in MDD for use in future economic evaluations of pharmacological treatments. Methods Embase, PubMed, Econlit, and Cochrane databases, plus gray literature, were searched from January 1998 to December 21, 2018, with no language or geographical restrictions, for relevant studies that reported HSUVs and disutilities for patients with MDD receiving pharmacological interventions. Results 443 studies were identified; 79 met the inclusion criteria. We focused on a subgroup of 28 articles that reported primary utility data from 16 unique studies of MDD treated with pharmacological interventions. HSUVs were elicited using EQ-5D (13/16, 81%; EQ-5D-3L: 11/16, 69%; EQ-5D-3L or EQ-5D-5L not specified: 2/16), EQ-VAS (5/16, 31%), and standard gamble (1/16, 6%). Most studies reported baseline HSUVs defined by study entry criteria. HSUVs for a first or recurrent major depressive episode (MDE) ranged from 0.33 to 0.544 and expanded from 0.2 to 0.61 for patients with and without painful physical symptoms, respectively. HSUVs for an MDE with inadequate treatment response ranged from 0.337 to 0.449. Three studies reported HSUVs defined by MADRS or HAMD-17 clinical thresholds. There was a large amount of heterogeneity in patient characteristics between the studies. One study reported disutility estimates associated with treatment side effects. Conclusions Published HSUVs in MDD, elicited using methods accepted by health technology assessment bodies, are available for future economic evaluations. However, the evidence base is limited, and it is important to select appropriate HSUVs for the intervention being evaluated and that align with clinical health state definitions used within an economic model. Future studies are recommended to elicit HSUVs for new treatments and their side effects and add to the existing evidence where data are lacking.

Abstract
BACKGROUND The study explores the association between pain and functional impairment in patients with partially remitted MDD, considering both clinician and patient reported outcomes. METHODS Multicenter, observational, and cross-sectional study, with 583 outpatients with partially remitted MDD. Measures of pain intensity (VAS), functional impairment (SOFAS), depressive symptomatology (HAM-D6), and remission from MDD and functional status from a patient-centered perspective (RDQ) were collected. VAS scores (cut-off: 30) were used to divide the sample in two groups: no pain (n = 274) and pain (n = 309). Descriptive data, correlation and regression analyses were obtained. RESULTS Functional impairment (SOFAS) and pain (VAS) were negatively and significantly correlated in the total sample, and in the group with pain. Lower pain predicted higher functioning. The pain sub-sample was older, less educated, with higher medical comorbidities, higher HAM-D6 scores, and lower functionality (SOFAS). In the RDQ, the pain group showed significantly higher scores in the symptom-related subscales, and lower scores in the subscales related to positive mental health, functioning and wellbeing. LIMITATIONS Correlational and observational design. The criteria and instruments used to measure pain and to define a threshold might limit the generalizability of findings. CONCLUSIONS Pain and functionality should be assessed and treated in patients with MDD in partial remission. Our results indicate that functionality should be assessed with a broader perspective, that also considers positive mental health features.

Abstract
OBJECTIVE To estimate a minimal clinically important difference (MCID) on the adult ADHD Quality of Life (AAQoL) scale. METHOD The MCID was determined from data from short-term ( N = 537) and long-term ( N = 440), placebo-controlled atomoxetine trials in adults with ADHD. For the anchor-based approach, change in clinician-rated Clinical Global Impressions-ADHD-Severity (CGI-ADHD-S) scores was used to derive MCID. For the distribution-based approach, baseline-to-endpoint mean ( SD) changes in AAQoL scores corresponding to 0.5 SD were computed. RESULTS The MCID was similar (approximately 8-point difference) between the short-term and the long-term treatment groups when either the anchor-based or distribution-based approach was used. CONCLUSION These results suggest that approximately 8 points in the change from baseline on the AAQoL is a MCID.

Abstract
INTRODUCTION The present study analyzes functioning during the course of treatment of a major depressive disorder in Mainland China, Taiwan, and Hong Kong. METHODS Data in this post hoc analysis were taken from a 24-week prospective, observational study in 12 countries worldwide. Of these, 422 patients were included from Mainland China (N = 205; 48.6%), Taiwan (N = 199; 47.2%), and Hong Kong (N = 18; 4.2%). Functioning was measured with the Sheehan Disability Scale, pain with the Somatic Symptom Inventory, and depression severity with the Quick Inventory of Depressive Symptomatology Self Report 16. Patients were classified as having no pain, persistent pain, or remitted pain. A mixed model with repeated measures was fitted to analyze the relationship between pain and functioning, adjusting for severity and other factors. RESULTS At baseline, 40% of the patients had painful physical symptoms. At 24 weeks, 6% of the patients had persistent pain. Sixty percent of the patients achieved remission. Patients with pain had a higher severity of depression score and lower functioning (P < .05) at baseline. At 24 weeks, patients with persistent pain had lower functioning (P < .05). The regression model found that clinical remission was associated with higher functioning at endpoint and that patients with persistent pain had lower functioning at endpoint when compared with the no-pain group. CONCLUSIONS Patients presenting with pain had lower functioning at baseline. At 24 weeks, pain persistence was associated with significantly lower functioning as measured by the Sheehan Disability Scale. Clinical remission was associated with better functional outcomes. The course of pain was related to achieving remission.

Abstract
This study was performed to examine the comorbidity risks between psychological disorders, such as depression, and gastroesophageal reflux disease (GERD) using nationally representative data from a National Sample Cohort of the National Health Insurance Service in Korea.The National Health Insurance Service-National Sample Cohort (NHIS-NSC) database from 2010 to 2012 was used in this study. GERD patients were defined as those diagnosed with specific tests, with screened medication, and without any other gastrointestinal diseases. Propensity score matching for age, sex, and economic status was applied to form a control cohort. Incidence rate, relative risks, Cox proportional-hazards modeling, and Kaplan-Meier analysis were applied to examine the differences between the GERD and control cohorts with regard to the risk of subsequent psychological disorders.The results showed that patients in the GERD cohort (n = 9503) had significantly higher risks of psychological disorders than those without GERD (adjusted hazard ratio [HR] 1.25, 95% confidence interval [CI] 1.07-1.47, P = .006). Specifically, the risk of depressive disorder was significantly higher for patients in the GERD cohort than in the control cohort (adjusted HR 1.41, 95% CI 1.04-1.91, P = .027). Kaplan-Meier analysis showed that the estimated probability of psychological disorders was significantly higher in the GERD cohort compared with the control cohort (log-rank test, P = .007).This study suggested that GERD may be a risk factor for subsequent psychological disorders, specifically, depressive disorder. The results of this study in GERD patients compared with non-GERD patients in Korea suggested that psychological disorders and GERD may be inter-related.

Abstract
OBJECTIVE We investigated the depression outcomes and the factors associated with pain persistence in Asian patients treated for major depressive disorder (MDD). METHODS This observational study enrolled 909 Asian adult inpatients and outpatients. The presence or absence of painful physical symptoms and severity of depression were assessed at baseline and after three months of treatment. Factors associated with pain persistence and outcome of depression were investigated using regression methods. RESULTS Of the 909 patients enrolled, 684 were included in the analysis and evaluated at three months. Of them, 335 (49%) had no pain at baseline nor follow up, 198 (29%) at baseline but not at follow up and 151 (22%) in both assessments. Pain more frequently persisted in patients who were divorced/widowed/separated, with >1 comorbidity, aged <40 years, with previous MDD episodes, taking pain medications, and with greater depression severity. At three months, response/remission were 84%/73% in the no pain group, 83%/63% in the remitted pain group and 46%/25% in the persistent pain group (differences all p < .0001; all bivariate comparisons were statistically significant with p < .05 except response between no pain and remitted pain). Persistent pain was also associated with less improvement in quality of life and health state. CONCLUSIONS Pain should be taken into account when diagnosing MDD and when tailoring therapy.

Abstract
OBJECTIVE The objective of this study was to assess the effectiveness of duloxetine monotherapy, in comparison with selective serotonin reuptake inhibitor (SSRI) monotherapy, in the treatment of painful physical symptoms (PPS) in Japanese patients with major depressive disorder (MDD) in real-world clinical settings. METHODS This was a multicenter, 12-week prospective, observational study. This study enrolled MDD patients with at least moderate PPS, defined as a Brief Pain Inventory-Short Form (BPI-SF) average pain score (item 5) ≥3. Patients were treated with duloxetine or SSRIs (escitalopram, sertraline, paroxetine, or fluvoxamine) for 12 weeks, and PPS were assessed by BPI-SF average pain score. The primary outcome was early improvement in the BPI-SF average pain score at 4 weeks post-baseline. RESULTS A total of 523 patients were evaluated for treatment effectiveness (duloxetine N=273, SSRIs N=250). The difference in BPI-SF average pain score between the two groups was not statistically significant at 4 weeks post-baseline, the primary endpoint (least-squares mean change from baseline [95% confidence interval]: duloxetine, -2.8 [-3.1, -2.6]; SSRIs, -2.5 [-2.8, -2.3]; P=0.166). There was a numerical advantage for duloxetine in improvement from 4 to 12 weeks post-baseline, and the difference was statistically significant at 8 weeks post-baseline (least-squares mean change from baseline [95% confidence interval]: duloxetine, -3.6 [-3.9, -3.3]; SSRIs, -3.1 [-3.4, -2.8]; P=0.023). The 30% and 50% responder rates were significantly higher in patients treated with duloxetine at 4 and 8 weeks post-baseline. There were no serious adverse events experienced by duloxetine-treated patients. The rate of discontinuations due to adverse events was similar for duloxetine and the SSRIs (1.0% and 0.8% of patients, respectively). CONCLUSION In this observational study, BPI-SF improvement was not significantly different at 4 weeks, the primary endpoint; however, patients treated with duloxetine tended to show better improvement in PPS compared to those treated with SSRIs.

Abstract
OBJECTIVE We determined if early improvement in painful physical symptoms (PPS) can be a predictor of remission in the treatment of major depressive disorder (MDD). METHODS We included randomized, double-blind, parallel-group clinical trials of duloxetine (40-60 mg/day) versus placebo for the acute treatment of MDD with associated PPS. Only those studies using the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Brief Pain Inventory - Short Form (BPI-SF) were included. Three studies met all criteria and included male or female outpatients aged ≥18 years who met the diagnostic criteria for MDD, had a MADRS total score ≥20, and had at least moderate pain (BPI-SF average pain score ≥3). Positive predictive values (PPVs) and negative predictive values (NPVs) of early improvement in PPS for remission were analyzed. PPVs were the proportion of patients with remission (MADRS total score ≤10) at week 8 out of patients who experienced early improvement in BPI-SF average pain score (≥30% decrease from baseline at week 1, 2, or 4). NPVs were the proportion of patients without remission (MADRS total score >10) at week 8 out of patients who did not experience early improvement in PPS. RESULTS Data from 1,320 patients were analyzed (duloxetine N=641 and placebo N=679). The overall remission (MADRS total score ≤10 at week 8) rate for the duloxetine group was significantly higher than the placebo group (38.5% vs 21.8%; P<0.0001). For both treatment groups, PPVs of early improvement in BPI-SF (30% improvement from baseline) were higher than the overall remission rate for all weeks examined (weeks 1, 2, and 4); in general, NPVs of early improvement in BPI-SF for nonremission were higher than the overall nonremission rate. CONCLUSION Early improvement in PPS can be a useful clinical indicator of subsequent treatment outcome for MDD patients with associated PPS.

Abstract
The aim of this study was to clarify how painful physical symptoms affect treatment outcomes in patients with melancholic major depressive disorder. The subjects comprised 100 consecutive Japanese outpatients with melancholic major depressive disorder who visited our clinic from October 2011 to October 2014. All subjects were interviewed for Diagnostic and Statistical Manual of Mental Disorders Axis 2, 3, and 4 and family history of major depressive disorder, and then grouped according to the presence of painful physical symptoms. We evaluated painful physical symptoms at baseline and after 12, 24, and 36 weeks of treatment and scores on the 17-item Hamilton Rating Scale for Depression, compared major depressive disorder remission between groups, and assessed responsiveness to antidepressants. The group with painful physical symptoms had a significantly more positive family history of major depressive disorder. The major depressive disorder remission rate was high in both groups, and no significant differences were observed. However, a significant relationship between major depressive disorder and painful physical symptoms remission was observed in the group with painful physical symptoms. A significantly higher number of remitted patients with painful physical symptoms (N=61) were administered serotonin-noradrenaline reuptake inhibitors, with significantly more receiving duloxetine than milnacipran.

Abstract
In treating Major Depressive Disorder with associated painful physical symptoms (PPS), the effect of duloxetine on PPS has been shown to decompose into a direct effect on PPS and an indirect effect on PPS via depressive symptoms (DS) improvement. To evaluate the changes in relative contributions of the direct and indirect effects over time, we analyzed pooled data from 3 randomized double-blind studies comparing duloxetine 60 mg/d with placebo in patients with major depressive disorder and PPS. Changes from baseline in Montgomery-Åsberg Depression Rating Scale total and Brief Pain Inventory-Short Form average pain score were assessed over 8 weeks. Path analysis examined the (1) direct effect of treatment on PPS and/or indirect effect on PPS via DS improvement and (2) direct effect of treatment on DS and/or indirect effect on DS via PPS improvement. At week 1, the direct effect of duloxetine on PPS (75.3%) was greater than the indirect effect through DS improvement (24.7%) but became less (22.6%) than the indirect effect (77.4%) by week 8. Initially, the direct effect of duloxetine on PPS was markedly greater than its indirect effect, whereas later the indirect effect predominated. Conversely, at week 1, the direct effect of treatment on DS (46.4%) was less than the indirect effect (53.6%), and by week 8 it superseded (62.6%) the indirect effect (37.4%). Thus, duloxetine would relieve PPS directly in the initial phase and indirectly via improving DS in the later phase.

Abstract
The aim of the study was to determine whether baseline pain was associated with discernible clinical features and treatment outcomes for patients with major depressive disorder (MDD) receiving 6-week fluoxetine treatment. A total of 131 inpatients with acutely ill MDD were enrolled to receive 20 mg of fluoxetine daily for 6 weeks. Pain was measured by the Short-Form 36 body pain index. Symptom severity, functional impairment, and severity of adverse events were assessed at baseline and again at weeks 1 to 4 and 6 using the 17-item Hamilton Depression Rating Scale, Modified Work and Social Adjustment Scale, and Utvalg for Kliniske Undersogelser Side Effect Rating Scale, respectively. Simple linear regression was employed to examine the clinical variables significantly associated with pain. The generalized estimating equations method was used to analyze the influence of pain on the 17-item Hamilton Depression Rating Scale, Modified Work and Social Adjustment Scale, and Utvalg for Kliniske Undersogelser Side Effect Rating Scale over time. Of the 131 participants, 119 (90.8%) who completed baseline pain measurements and had at least 1 postbaseline assessment were included in the analysis. Patients experiencing greater pain were more likely to have more severe depression, to be at greater risk of suicide, to have functional impairment, to experience stressful life events, and to have poor treatment outcomes. These findings suggest that pain was significantly associated with multiple aspects of patients with MDD. Patients with MDD with higher levels of pain were clinically useful in predicting poor outcomes after acute fluoxetine treatment.

Abstract
INTRODUCTION This was an analysis of the impact of somatic symptoms on the severity and course of depression in Chinese patients treated for an acute episode of major depressive disorder (MDD). METHODS Data were extracted from a 3-month prospective observational study which enrolled 909 patients with MDD in psychiatric care settings; this analysis focused on the Chinese patients (n=300). Depression severity was assessed using the Clinical Global Impression of Severity (CGI-S) and 17-item Hamilton Depression Rating Scale (HAMD-17); somatic symptoms were assessed using the patient-rated 28-item Somatic Symptom Inventory (SSI). Cluster analysis using baseline SSI scores grouped patients into three clusters with no/mild, moderate, or severe somatic symptoms. Four SSI factors (pain, autonomic symptoms, energy, and central nervous system) were defined, and regression analyses identified which factors were associated with remission at 3 months. RESULTS More than 70% of the patients had moderate or severe somatic symptoms. Baseline depression severity (HAMD-17 and CGI-S scores) was associated with more severe somatic symptoms. Remission rates differed between clusters of patients: 84.1%, 72.0%, and 55.3% for no/mild, moderate, and severe somatic symptoms, respectively (P=0.0034). Pain symptoms were the somatic symptoms more strongly associated with lower remission rates at 3 months. DISCUSSION Somatic symptoms are associated with greater clinical severity and lower remission rates. Among somatic symptoms, pain symptoms have the greatest prognostic value and should be taken into account when treating patients with depression.

Abstract
BACKGROUND We hypothesize that depression in type 2 diabetes might be associated with poor glycemic control, in part due to suboptimal self-care. We tested this hypothesis by examining the associations of depression with clinical and laboratory findings in a multicenter survey of Chinese type 2 diabetic patients. METHOD 2538 patients aged 18-75 years attending hospital-based clinics in four cities in China underwent detailed clinical-psychological-behavioral assessment during a 12-month period between 2011 and 2012. Depression was diagnosed if Patient Health Questionnaire-9 (PHQ-9) score ≥10. Diabetes self-care and medication adherence were assessed using the Summary of Diabetes Self-care Activities and the 4-item Morisky medication adherence scale respectively. RESULTS In this cross-sectional study (mean age: 56.4 ± 10.5[SD] years, 53% men), 6.1% (n = 155) had depression. After controlling for study sites, patients with depression had higher HbA(1c) (7.9 ± 2.0 vs. 7.7 ± 2.0%, P = 0.008) and were less likely to achieve HbA(1c) goal of <7.0% (36.2% vs 45.6%, P = 0.004) than those without depression. They were more likely to report hypoglycemia and to have fewer days of being adherent to their recommended diet, exercise, foot care and medication. In logistic regression, apart from young age, poor education, long disease duration, tobacco use, high body mass index, use of insulin, depression was independently associated with failure to attain HbA(1c) target (Odds Ratio [OR] = 1.56, 95%CI:1.05-2.32, P = 0.028). The association between depression and glycemic control became non-significant after inclusion of adherence to diet, exercise and medication (OR = 1.48, 95% CI 0.99-2.21, P = 0.058). CONCLUSION Depression in type 2 diabetes was closely associated with hyperglycemia and hypoglycemia, which might be partly mediated through poor treatment adherence.

Vietri J, Otsubo T, Montgomery W, Tsuji T, Harada E. The incremental burden of pain in patients with depression: results of a Japanese survey. BMC Psychiatry 2015; 15:104. [PMID: 25947635 PMCID: PMC4424963 DOI: 10.1186/s12888-015-0488-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2014] [Accepted: 04/24/2015] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Major depressive disorder (MDD) is a chronic mental illness which affects an estimated 3% of the Japanese population. Many patients with MDD report painful physical symptoms, and research outside of Japan suggests such patients may represent a subtype of depression which is more severe and difficult to treat. There is no evidence available about the characteristics or incremental burden of these patients in Japan. The objective of this study was to quantify the incremental burden of physical pain among individuals in Japan diagnosed with depression. METHODS Data for individuals age 18 and older who reported a physician diagnosis of depression were obtained from the Japan National Health and Wellness Survey (NHWS). Respondents who also reported physical pain were matched to respondents who did not report pain using propensity scores and compared using bivariate statistics. Measures included Patient Health Questionnaire (PHQ-9) for depression severity, Medical Outcomes Study 12-Item Short Form Survey Instrument (SF-12v2) for health-related quality of life, the Work Productivity and Activity Impairment (WPAI) for work and activity impairment, and 6-month report of health care use. RESULTS Individuals with depression who reported physical pain had higher PHQ-9 depression scores (14.3 vs. 11.1, p<0.001), lower health-related quality of life (Mental Component Summary score [MCS] 29.1 vs. 32.0, p<0.01; Physical Component Summary score [PCS] 43.0 vs. 47.2, p<0.001; health utility [SF-6D] 0.567 vs. 0.613, p<0.001), more presenteeism (46.3% vs. 36.8%, p<0.01), more overall work impairment (51.4% vs. 42.3%, p<0.01), more activity impairment (55.4% vs. 43.9%, p<0.001), and reported using more health care provider visits in the prior 6 months (17.7 vs. 12.8, p<0.01) as well as hospitalizations (1.7 vs. 0.8, p<0.05) relative to propensity-score matched controls without pain. Absenteeism (13.1% vs. 11.4%, p=0.51) and emergency room visits (0.31 vs. 0.35, p=0.76) were not significantly different between the two matched groups. CONCLUSIONS Individuals whose depression is accompanied by physical pain have a higher burden of illness than those whose depression does not include physical pain. Clinicians should take the presence of pain into account and consider treating both the physical and emotional symptoms of these patients.

Abstract
OBJECTIVE This study investigated whether painful physical symptoms (PPSs) influenced quality of life (QoL) when adjusting for severity of depression. METHODS Severity of depression, QoL and PPSs were assessed at baseline and 3 months among the Chinese cohort (n = 300) of a 3-month observational study of major depressive disorder (MDD) in East Asia. The presence of PPS was defined as 'a mean score of ≥2 on the Somatic Symptom Inventory pain-related items'. Regression analyses determined predictors of QoL at 3 months, adjusting for age, sex, depressive symptoms, overall severity and QoL at baseline. RESULTS PPSs were present (PPS+) at baseline in 35.3% of patients. Over 3 months, in the whole sample, EuroQoL visual analogue scale (EQ-VAS) score improved from 45.5 (standard deviation [SD]: 20.9) to 81 (SD: 16.7), and EuroQoL 5-Dimension Questionnaire (EQ-5D) score improved from 0.52 (SD: 0.31) to 0.89 (0.16). At 3 months, mean EQ-VAS was 75.9 (SD: 17.7) for PPS+ versus 83.7 (SD: 15.6) for PPS-, and mean EQ-5D was 0.83 (SD: 0.17) versus 0.92 (SD: 0.14). PPS+ at baseline was a significant predictor of QoL at 3 months after adjusting for socio-demographic and baseline clinical variables. CONCLUSIONS PPSs were associated with less improvement in QoL in patients receiving treatment for MDD, independent of severity of depression.

Abstract
BACKGROUND Depression is often associated with painful physical symptoms. Previous research has seldom assessed the relationship between the severity of physical symptoms and the severity of mental and emotional symptoms of depression or other health outcomes, and no such studies have been conducted previously among individuals with depression in Japan. The aim of this study was to assess the relationship between the severity of physical pain and depression and other outcomes among individuals in Japan diagnosed with depression. METHODS Data for individuals aged 18 and older in Japan who reported being diagnosed with depression and also reported physical pain were obtained from the Japan National Health and Wellness Survey. These respondents were characterized on sociodemographics and health characteristics, and the relationship between ratings of severity on pain in the last week and health outcomes were assessed using bivariate correlations and generalized linear models. Measures included the Patient Health Questionnaire for depression severity, Medical Outcomes Study 12-Item Short Form Survey Instrument for health-related quality of life, the Work Productivity and Activity Impairment for work and activity impairment, and 6-month report of health care use. RESULTS More severe physical pain in the past week was correlated with more severe depression, worse health-related quality of life, lower health utility, greater impairment at work, and more health care provider visits. These relationships remained significant after incorporating sociodemographics and health characteristics in the statistical models. CONCLUSION Individuals whose depression is accompanied by more severe physical pain have a higher burden of illness than those whose depression includes less severe pain, suggesting that even partially ameliorating painful physical symptoms may significantly benefit patients with depression. Clinicians should take the presence and severity of physical pain into account and consider treating both the physical and emotional symptoms of these patients.

Abstract
PURPOSE To describe pharmacological treatment patterns in Asian patients with major depressive disorder (MDD), including duration of treatment, reasons for medication discontinuation, rate of medication nonadherence, factors associated with medication nonadherence, and impact of medication nonadherence on depression outcomes. PATIENTS AND METHODS Data were from a prospective, observational 3-month study of East Asian MDD inpatients from 40 sites in six East Asian countries who initiated antidepressant treatment at baseline (n=569). Assessments included the Clinical Global Impression-Severity scale (CGI-S), 17-item Hamilton Depression Rating Scale (HAMD-17), painful physical symptoms, response and remission, employment status, quality of life (QoL) (EuroQOL Questionnaire-5 Dimensions [EQ-5D]) and health state using the visual analog scale, adherence by clinician opinion, and patient self-report. Cox proportional hazards modeling, Kaplan-Meier survival analysis, and regression modeling were employed. RESULTS Median time to discontinuation for any reason was 70 days (95% confidence interval: 47; 95). Reasons for discontinuation were inadequate response in 64.1%, nonadherence in 6.2%, and adverse events in 4.1%; 25.6% who discontinued experienced an adequate response to treatment. In those patients who had an adequate response, age and country were significantly associated with time to medication discontinuation. Patient-reported nonadherence was 57.5% and clinician-reported nonadherence was 14.6% (62/426). At 3 months, nonadherent patients had significantly higher disease severity (CGI-S, P=0.0001; HAMD-17, P<0.0001), lower QoL ratings (EQ-5D tariff, P=0.0007; EQ-5D visual analog scale, P=0.0024), and lower response and remission rates (both P<0.0001) compared with adherent patients. The odds of response and remission were greater among adherent patients. CONCLUSION Early discontinuation of antidepressants among Asian MDD patients was high. A total of 25.6% who discontinued prematurely were experiencing an adequate response to treatment. Nonadherent patients had significantly higher disease severity, lower QoL ratings, and lower response and remission rates compared with adherent patients.

Abstract
ABSTRACT Background: Painful physical symptoms (PPS) are prevalent among elderly patients with depression. We describe the impact of PPS on depression outcomes and quality of life (QOL) of elderly Asian patients with major depressive disorder (MDD). Methods: This post hoc analysis of data from a three-month prospective observational study of East Asian MDD in- or out-patients focused on elderly patients aged ≥60 years. Depression severity was evaluated using the Hamilton depression (HAMD-17) and clinical global impression of severity (CGI-S) scales, while QOL was measured using EuroQOL (EQ-5D and EQ-VAS) instruments. PPS were rated using the modified somatic symptom inventory (SSI). Results: At baseline, depression was moderate to severe and 49% of the 146 elderly patients were painful physical symptom positive (PPS+). Bivariate analysis showed significant correlations between PPS and depression severity and QOL at baseline. Linear regression models showed the baseline factor most significantly associated with depression severity at three months was baseline PPS status. PPS+ patients had a mean increase of 2.87 points in their HAMD-17 rating and 0.77 points in their CGI-S score. Response and remission were significantly lower in PPS+ patients; response was 60% and remission was 40% in PPS+ patients while 82% and 66% in painful physical symptom negative (PPS-) patients. QOL at endpoint was lower in PPS+ patients. Conclusions: PPS are common in elderly Asian patients with MDD and negatively influence depression outcomes and QOL. Patients with PPS had lower QOL at baseline, lower response and remission rates, higher severity of depression, and lower QOL after three months of treatment.

Abstract
OBJECTIVE The objective of this evidence-based structured review was to determine if there is consistent evidence that pain interferes with achieving antidepressant treatment response/remission of depression in patients with depression and pain. METHODS After exclusion criteria were applied, of 2,801 studies/reports, 17 studies addressed this question. They were sorted into the four hypotheses outlined herein after. The percentage of studies supporting/not supporting each hypothesis was calculated. The strength and consistency of the evidence for each hypothesis were rated according to the Agency for Health Care Research and Quality (AHRQ) guidelines. RESULTS For the first hypothesis (pretreatment pain levels will predict antidepressant depression response), nine out of 10 (90%) studies supported it. For the second hypothesis (treatment decreases in pain will be associated with antidepressant depression response), two out of two (100%) studies supported it. For the third hypothesis (pretreatment pain levels will predict antidepressant depression remission), six out of six (100%) studies supported it. For the fourth hypothesis (treatment decreases in pain will be associated with antidepressant depression remission), five out of five (100%) supported it. Utilizing these percentages and AHRQ guidelines, hypotheses 1, 3, and 4 received an A rating for consistency of studies in supporting them. A consistency rating for hypothesis 2 could not be generated because of too few studies in that group. CONCLUSIONS Consistent evidence was found that antidepressant treatment of depression in patients with depression and pain can be negatively impacted by pain for achieving depression response/remission. However, the overall number of studies supporting each hypothesis was small. In addition, several potential confounders of the results of this study were identified.

Abstract
INTRODUCTION The Hamilton Depression Rating Scale (HDRS) is the most widely used depression rating scale worldwide. Reliability of HDRS has been reported mainly from Western countries. The current study tested the reliability of HDRS ratings among psychiatric residents in Indonesia, before and after HDRS training. The hypotheses were that: (i) prior to the training reliability of HDRS ratings is poor; and (ii) HDRS training can improve reliability of HDRS ratings to excellent levels. Furthermore, we explored cultural validity at item level. METHODS Videotaped HDRS interviews were rated by 30 psychiatric residents before and after 1 day of HDRS training. Based on a gold standard rating, percentage correct ratings and deviation from the standard were calculated. RESULTS Correct ratings increased from 83% to 99% at item level and from 70% to 100% for the total rating. The average deviation from the gold standard rating improved from 0.07 to 0.02 at item level and from 2.97 to 0.46 for the total rating. DISCUSSION HDRS assessment by psychiatric trainees in Indonesia without prior training is unreliable. A short, evidence-based HDRS training improves reliability to near perfect levels. The outlined training program could serve as a template for HDRS trainings. HDRS items that may be less valid for assessment of depression severity in Indonesia are discussed.

Abstract
OBJECTIVE To investigate the impact of somatic symptoms on the severity and course of depression in Asian patients treated for an acute episode of major depressive disorder (MDD). METHODS Three-month prospective observational study of 917 patients with MDD in psychiatric care settings of which 909 had complete main baseline data. Depression severity was assessed using the physician-rated Clinical Global Impression of Severity (CGI-S) and 17-item Hamilton Depression Rating Scale (HAMD17), and somatic symptoms were assessed using the patient-rated 28-item Somatic Symptom Inventory (SSI). Cluster analysis using baseline SSI scores grouped patients into 3 clusters with no/few, moderate or severe somatic symptoms. Four factors of SSI (pain, autonomic symptoms, energy, and central nervous system) were defined and regression analyses identified which factors were associated with remission and response at 3 months follow-up. RESULTS Baseline depression severity (HAMD17 and CGI-S scores) was associated with more severe somatic symptoms. Remission rates differed between clusters of patients: 68.4%, 54.7% and 29.3% for no/few, moderate and severe somatic symptoms, respectively (p<0.0001). Corresponding response rates were 81.8%, 72.1% and 55.2% (p<0.0001). Pain symptoms were the somatic symptoms most associated with these clinical outcomes at 3 months. LIMITATIONS Only patients diagnosed with MDD in psychiatric care were assessed. CONCLUSIONS Somatic symptoms are frequent among Asian patients in psychiatric care for MDD and are associated with greater clinical severity and lower response and remission rates. Among somatic symptoms, pain symptoms have the greatest prognostic value and should be taken into account when treating patients with depression.

Abstract
BACKGROUND Patients with major depressive disorder (MDD) may suffer from concomitant pain symptoms. The aim of this study is to determine whether the presence of painful physical symptoms (PPS) influences quality of life when taking into account baseline depression severity. METHODS Patients with a new or first episode of MDD (n = 909) were enrolled in a 3-month prospective observational study in East Asia. The Hamilton Depression Rating Scale, Clinical Global Impression-Severity score, Somatic Symptom Inventory, and EuroQoL questionnaire-5 Dimensions (EQ-5D) and EQ-Visual Analogue Scale (EQ-VAS) were assessed at baseline and 3 months' follow-up. The presence of PPS was defined as a mean score of ≥2 on the Somatic Symptom Inventory pain-related items. Regression analyses determined predictors of quality of life at 3 months, adjusting for age, sex, depressive symptoms, overall severity, and quality of life at baseline. RESULTS PPS were present (PPS+) at baseline in 52% of patients. During the 3-month follow-up, EQ-VAS scores improved from 47.7 (standard deviation [SD] 20.6) to 72.5 (SD 20.4), and EQ-5D improved from 0.48 (SD 0.34) to 0.80 (SD 0.26). At 3 months, mean EQ-VAS was 66.4 (SD 21.2) for baseline PPS+ patients versus 78.5 (SD 17.6) for baseline PPS- patients, and mean EQ-5D was 0.71 (SD 0.29) versus 0.89 (SD 0.18). PPS+ at baseline was a significant predictor of quality of life at 3 months after adjusting for sociodemographic and baseline clinical variables. CONCLUSION The presence of painful physical symptoms is associated with less improvement in quality of life in patients receiving treatment for major depression, even when adjusting for depression severity.

Abstract
OBJECTIVE This retrospective post-hoc analysis of observational studies assesses the frequency of painful physical symptoms (PPS) in patients with major depressive disorder (MDD) of varied severity as may be seen in clinical practice. METHODS Observational studies of MDD that collected a clinician-reported measure of depression severity and included assessment of PPS were screened for this individual patient-level analysis. Six observational studies were included that enrolled outpatients with a diagnosis of MDD (assessed using the 17-item Hamilton depression scale, Hospital Anxiety and Depression Scale-Depression, or Inventory of Depressive Symptomatology). Measures of PPS were based on the original study assessment (modified Somatic Symptom Inventory [SSI] and Visual Analogue Scale [VAS]). Patients were divided into analysis cohorts based on the presence or absence of PPS. To model PPS status, odds ratios were calculated from logistic regression for cross-sectional analysis (main analysis) and generalized linear mixed models for longitudinal models (exploratory longitudinal analysis). RESULTS For the main analysis, four studies (N = 2943, 71.6% female, mean age 45.3 years) were identified. Of 2901 eligible patients, 61.7% were classified as having painful physical symptoms (PPS+). At study entry, 73.1% (957/1309) of patients in the severe category of depression, 56.8% (537/945) of those with moderate depression, and 45.6% (295/647) of those with mild depression were PPS+. The exploratory longitudinal analysis was performed using a subset (N = 2430) from the studies used in the main analysis plus two others (an additional 7984 patients, 6742 of which were modeled). The likelihood of patients that were PPS- at baseline later developing PPS was 5% to 13% greater for patients with increased depression severity (P < 0.001) and the likelihood of PPS+ patients later not having PPS was 9% to 17% less for patients with increased depression severity (P < 0.0001). CONCLUSIONS Since this is a retrospective aggregate analysis of several observational studies, and due to missing data, care should be taken in the interpretation of these results. Despite the use of adjustment techniques, selection bias and unmeasured confounding may still be an issue for comparative analysis as not all variables were collected for all studies. For patients treated in typical care settings, PPS were associated with depression severity. However, patients with mild and moderate depression also exhibited PPS. Clinicians should be aware that PPS are present, and may warrant treatment, across depression severities.

Abstract
BACKGROUND There is a lack of population-based long-term longitudinal research on mental health status and functional physical/somatic symptoms. Little is known about the long-term mental health outcomes associated with somatic symptoms or the temporal relationship between depression and such symptoms. This 15-year study followed up adolescents with depression and matched controls, screened from a population-based sample, who reported different numbers of somatic symptoms. METHODS The total population of 16-17-year-olds in Uppsala, Sweden, was screened for depression in 1991-1993. Adolescents who screened positive and an equal number of healthy controls took part in a semi-structured diagnostic interview. In addition, 21 different self-rated somatic symptoms were assessed. Sixty-four percent of those adolescents participated in a follow-up structured interview 15 years later. RESULTS Somatic symptoms in adolescence predicted depression and other adult mental disorders regardless of the presence of adolescent depression. In adolescents with depression, the number of functional somatic symptoms predicted, in a dose response relationship, suicidal behavior, bipolar episodes, and psychotic episodes as well as chronic and recurrent depression. Contrary to expectations, the somatic symptoms of abdominal pain and perspiration without exertion better predicted depression than all DSM-IV depressive symptoms. Abdominal pain persisted as an independent strong predictor of depression and anxiety, even after controlling for other important confounders. CONCLUSIONS Somatic symptoms in adolescence can predict severe adult mental health disorders. The number of somatic symptoms concurrent with adolescent depression is, in a stepwise manner, linked to suicidal attempts, bipolar disorders, psychotic disorders, and recurrent and chronic depression. These findings can be useful in developing treatment guidelines for patients with somatic symptoms.

Quality of life in major depressive disorder: the role of pain and pain catastrophizing cognition. Compr Psychiatry 2012; 53:387-95. [PMID: 21684536 DOI: 10.1016/j.comppsych.2011.05.005] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2010] [Revised: 05/05/2011] [Accepted: 05/09/2011] [Indexed: 11/24/2022] Open
Abstract
OBJECTIVE Pain symptoms are frequent complaints in patients with major depressive disorder (MDD). Although it is known that pain intensity and pain-related cognition predict quality of life (QOL) in patients with chronic pain, limited studies have examined their roles in MDD. The study aimed to determine whether pain and pain catastrophizing were independent predictors of QOL in MDD after accounting for the impact of anxiety and depression. METHODS This is a prospective, naturalistic follow-up study. Ninety-one Chinese patients were enrolled during an acute episode of MDD, 82 of them were reassessed 3 months later using the same assessment on pain, anxiety, depression, and QOL. Pain intensity was evaluated using a verbal rating scale and a visual analog scale. Quality of life was assessed using the 36-item Short Form Health Survey. Pain-related cognition was assessed at baseline with the Pain Catastrophizing Scale. RESULTS There was significant improvement in pain, anxiety, depression, and QOL from baseline to 3-month follow-up. Hierarchical regression analyses showed that pain intensity was significantly associated with QOL at baseline and 3 months. Pain complaint was more important than anxiety and depressive symptoms in predicting changes in both physical and psychosocial domains of QOL. After controlling for the severity of pain, anxiety, and depression, Pain Catastrophizing Scale score was independently associated with QOL in MDD. CONCLUSION The study supports the specific role of pain and pain-related cognition in predicting QOL in depressed patients. Further studies targeting pain-related cognition for improving the outcome of MDD are necessary.

Pain has a strong negative impact on the fluoxetine response in hospitalized patients with major depressive disorder. Clin J Pain 2012; 27:805-10.

Abstract
OBJECTIVES Response to an antidepressant is frequently the main goal in treating depression. The purpose of this study was to identify predictor(s) of response to the antidepressant, fluoxetine. METHODS One hundred thirty-one newly hospitalized patients with major depressive disorder received fluoxetine (20 mg/d) for 6 weeks. Symptom severity was assessed using the 17-item Hamilton Depression Rating Scale at weeks 0, 1, 2, 3, 4, and 6. Response was defined as a reduction of ≥50% of the 17-item Hamilton Depression Rating Scale score. We compared the responders and nonresponders in terms of baseline variables. Pain measures included the Short-Form-36 (SF-36) pain severity score and pain interference score. Univariate logistic regression was used to identify variables associated with fluoxetine response. RESULTS A total of 66 (58.9%) of the 112 completers were classified as responders after a 6-week treatment. The responders and nonresponders did not differ in baseline variables, except melancholic features (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria) and pain measures (SF-36). SF-36 pain severity score had the smallest P value (P=0.015). Its odds ratio (0.70) means that each point increase in the score of pain severity is expected to decrease the chance of response by approximately 30%. CONCLUSIONS These findings from newly hospitalized patients with multiple pain measures support the previous studies, which enrolled mainly outpatients and found that a higher level of pain can have a strong negative impact on the antidepressant response. These data require confirmation and extension to outpatients and other antidepressants.

Abstract
This study investigated the sex differences, and the shared genetic and environmental factors underlying the associations of sleep disturbances (insomnia and sleep quality) with pain and somatic symptoms in both adolescents and middle-aged adults. We recruited 259 adolescents (69 with current insomnia) and their parents (256 middle-aged adults, 78 with current insomnia). Insomnia severity and sleep quality were measured by the Insomnia Severity Inventory (ISI) and Pittsburgh Sleep Quality Index (PSQI), respectively. Pain and somatic symptoms were measured by the Somatic Symptom Inventory and Visual Analogue Scale for overall pain. Subjects with insomnia scored higher on all measures of pain and somatic symptoms than non-insomnia patients, in both adolescents and adults (P<.001). Both pain and somatic measures were associated with ISI and PSQI scores after controlling for age, sex, depressive and anxiety symptoms. There was an interaction effect between insomnia and female sex on pain and somatic symptoms (P<.05), especially in adults. Pain and somatic symptoms ran in family with moderate heritability (range h(2)=0.15-0.42). The phenotypic associations of ISI and PSQI with pain and somatic measures were both contributed by genetic (range p(G)=0.41-0.96) and environmental (range p(E)=0.27-0.40) factors with a major genetic contribution. In summary, insomnia and poor sleep quality are closely associated with pain and somatic symptoms. Insomnia seems to modulate the sex differences in pain and somatic symptoms, especially in the adult population. A shared genetic predisposition might underlie the associations of insomnia and sleep quality with pain and somatic symptoms.

Abstract
OBJECTIVE To assess the reliability and validity of the Integral Inventory for Depression (IID) scale using post hoc analyses of data from a multi-country study (ClinicalTrials.gov: NCT00561509) of patients with major depressive disorder (MDD). METHODS Patients (N = 1629) completed the IID (comprising two separate dimensions for emotional and physically painful symptoms; maximum score of 65) and a reference scale (16-item Quick Inventory of Depressive Symptomatology Self-Report) at baseline and at follow-up (8 and 24 weeks). Physicians rated MDD symptoms using the Clinical Global Impressions of Severity scale at each visit. Inter-item correlation, internal consistency, external validity, factor structure, and exploratory analysis of an optimal severity cut-off point were assessed. RESULTS The IID displayed two distinct dimensions (i.e. painful and emotional) with little item redundancy and good internal consistency (Cronbach's α > 0.83 at each visit). The IID displayed good external validity (Pearson's correlations coefficients >0.60 at each visit) and statistically significant agreement (McNemar's test; P < 0.001 at follow-up) with the reference scale. Results suggest that a cut-off score of ≤24 had adequate precision (>80%) to identify patients with and without moderate MDD. CONCLUSIONS Results suggest that the IID may be a reliable and valid tool for assessing emotional and painful symptoms of MDD.

Abstract
AIM The goal of treating major depressive disorder is to achieve remission. This prospective study aimed to identify predictors of remission in a cohort of depressive inpatients who received fluoxetine. METHODS A total of 131 newly hospitalized patients with major depressive disorder received a fixed dose of 20 mg/day (the recommended dose from the literature) of fluoxetine for 6 weeks. Symptom severity was assessed using the 17-item Hamilton Depression Rating Scale at weeks 0, 1, 2, 3, 4 and 6. Remission was defined as a score of ≤7 on the 17-item Hamilton Depression Rating Scale after 6 weeks of treatment. We compared the remitters and non-remitters in terms of baseline variables. The Short-Form-36 pain interference item was used to assess pain. It was classified as high (score ≥ 3) or low (score < 3). RESULTS A total of 31 (27.7%) of 112 completers remitted after 6 weeks of treatment. The remitters and non-remitters did not differ in baseline variables, except pain interference, baseline depression severity, and depression improvement at week 1. CONCLUSION These findings obtained from newly hospitalized major depression patients support the previous notion that pain interference, depression severity, and early improvement can be the predictors for remission. Patients with high pain interference, a greater depression severity or a less early improvement are likely to require aggressive treatment early. These data require confirmation and extension to outpatients and other antidepressants.
