Psychiatric disorders and among them depression are common in substance dependent patients. The aim of this study is to compare the clinical characteristics of those that appear to have substance-induced depression and those that have independent major depression. One-hundred eighty-four independent and 187 opium-induced (OID) depressed male patients that met the DSM-IV criteria for major depressive disorder were randomly selected. Standard demographic data, including age, marital, employment and education status, were collected. The primary measure of depressive signs and symptoms was Hamilton Depression Scale (HAMD-21). The two groups were compared with each other for the HAMD total and subscales scores. The two groups were matched regarding age, educational level and marital status. Opium-induced depressed patients were more severely depressed and motor retarded and also they had more social and occupational problems. Gastrointestinal, sexual and somatic complaints were more common among them too. MDD patients had better insight than the other group. The results demonstrate that it is possible to differentiate between substance-induced and independent depression. Such differentiation might be important for establishing prognosis and optimal treatment.

Painful physical symptoms (PPS) are common in patients with depression. Our objective was to evaluate the presence of PPS in a sample of SSRI non- or partial-responders with MDD and examine the effect of a switch to duloxetine on those PPS. Outpatients who met criteria for MDD despite having taken an SSRI antidepressant for at least 6 weeks, and who had a Hamilton depression rating scale total score of at least 15 and a clinical global impression of severity score of at least 3, were randomized to switch to duloxetine by either a direct switch or a start-taper switch method. PPS were assessed at baseline and at the study endpoint using various measures including six visual analog scales (VAS) for pain (overall pain, headache, back pain, shoulder pain, interference with daily activities, and time in pain while awake), the pain subscale of the symptom questionnaire-somatic subscale, and the bodily pain subscale of the short form-36 item health survey. Clinically significant levels of pain (mean baseline VAS scores >30 mm) were seen across all VAS pain measures prior to switching. Switch to duloxetine was associated with significant improvements on all pain measures regardless of switch method, and there was evidence for an earlier reduction in pain in the start-taper switch group. In summary, MDD patients who were non- or partial-responders to SSRI treatment were found to have clinically significant pain which improved significantly following switch to duloxetine regardless of the switch method utilized.

The impact of persistent depression on social support (SS) is not well known. In the Vantaa Depression Study (VDS), 193 patients with DSM-IV MDD were interviewed at baseline, at 6 and 18 months. Objective SS was measured with the Interview Measure of Social Relationships (IMSR), and subjective SS with the Perceived Social Support Scale-Revised (PSSS-R); the influence of time spent in major depressive episodes (MDEs) on SS at 18 months was investigated. Low objective SS was independently predicted by low baseline objective SS, male gender, and longer time spent in MDEs; low subjective SS by longer time spent in MDEs and lower baseline subjective SS. Along with clinical improvement, subjective SS improved but objective SS did not. The persistence of MDD seems to weaken both objective and subjective SS. Whether this results in progressively weakening objective and subjective SS, and thereby lowers the threshold for future depressive episodes, should be further investigated.

The neural substrates of MDD (major depressive disorder) are complex and not yet fully understood. In the present review, I provide a short overview of the findings supporting the hypothesis of a dysfunctional dopamine system in the pathophysiology of depression. Because the mesocorticolimbic dopamine system is involved in reward processing, it has been hypothesized that a reduced function of this system could underlie the anhedonia and amotivation associated with depression. This hypothesis is supported by several observations providing indirect evidence for reduced central dopaminergic transmission in depression. However, some of the differences observed between controls and depressed patients in dopamine function seem to be specific to a subsample of patients, and influenced by the methods chosen. Studies that investigated the neural bases of some MDD behavioural symptoms showed that anhedonia, loss of motivation and the diminished ability to concentrate or make decisions could be associated with a blunted reaction to positive reinforcers and rewards on one side, and with a bias towards negative feedback on the other side. Only a few studies have investigated the neural basis of anhedonia and the responses to rewards in MDD subjects, mostly evidencing a blunted response to reward signals that was associated with reduced brain activation in regions associated with the brain reward system. In conclusion, there is evidence for a dysfunction of the dopamine system in depression and for blunted response to reward signals. However, the exact nature of this dysfunction is not yet clear and needs to be investigated in further studies.

Posttraumatic stress disorder (PTSD) is a severely debilitating anxiety disorder. Over 80% of patients with PTSD also exhibit other psychiatric condition, such as bipolar disorder (BP) or major depression (MDD). Previously, it has been found that p11 mRNA expression was significantly changed in post mortem cortex of patients with PTSD and depression. We hypothesize that p11 mRNA levels in the peripheral blood cells will be a potential biomarker for PTSD with heterogeneity in terms of type of trauma, time since trauma and duration of illness. We examined the peripheral blood mononuclear cell (PBMC) P11 mRNA of patients with PTSD (n=13), major depressive disorder (MDD, n=16), bipolar disorder (BP, n=24), and schizophrenia (SCZ, n=12) or controls (n=14) using quantitative real-time PCR and the circulating levels of cortisol in blood plasma and saliva of PTSD using radioimmunoassay kit CORT-CT2. The Hamilton Rating Scale for Depression (HAMD) and Anxiety (HARS), the Chinese version of the Davidson Trauma Scale-Frequency (CDTS-F) and the Chinese version of the Davidson Trauma Scale-Severity (CDTS-S), and Impact of Event Scale-Revised (IES-R) were administered. We found that patients with PTSD had lower levels of p11 mRNA than control subjects, while those with MDD, BP and SCZ had significantly higher p11 levels than the controls. P11 mRNA levels were positively correlated with the scores of HAMD (r=0.62, p<0.05), CDTS-F (r=0.71, p<0.05) and CDTS-S (r=0.62, p<0.05), while they did not correlate with scores of HARS and IES-R. Basal levels of plasma and salivary cortisol of PTSD patients were not statistically different from those of controls. Our findings suggest that PBMC p11 mRNA expression levels may serve as a potential biomarker to distinguish PTSD from BP, MDD and SCZ.

The present investigation reports on the use of problem solving therapy (PST) to treat depression in an 83-year-old woman with Parkinson's disease (PD) and concurrent mild cognitive impairment (MCI). A neuropsychological evaluation was conducted prior to the intervention and the patient demonstrated mild deficits of executive functioning and memory. The PST treatment consisted of 12 one-hour sessions that occurred weekly. Depressive symptoms were evaluated using the Hamilton Depression Rating scale and the Montgomery-Asberg Depression rating scale. At a post-treatment assessment (week 12), clinician assessment indicated that the client no longer met criteria for MDD. Weekly depression severity ratings showed significant reduction in severity of depressive symptoms over 12 weeks. Results at 1-month and 6-month follow-up demonstrated that the therapeutic gains were not only maintained, but that the client continued to improve. These results suggest that PST may be an effective treatment for the treatment of depression for individuals with a PD and concurrent MCI.

This paper presents a meta-analysis of studies examining prevalence of psychopathology among offspring of anxiety-disordered parents, with the purpose of determining overall risk among these offspring for developing anxiety and depressive disorders. Pooled odds ratios for these disorders among high-risk offspring, compared to offspring of psychiatric and non-psychiatric controls, were calculated. Sixteen papers (including three follow-up studies) were identified, encompassing 1892 offspring (ages 4-25 years). Results revealed that: (1) offspring of parents with anxiety disorders have greater risk for anxiety and depressive disorders than offspring of non-psychiatric controls (ORs=3.91 and 2.67, respectively) and greater risk for anxiety disorders than offspring of psychiatric controls (OR=1.84); (2) offspring of anxious parents have significantly greater odds of having each type of anxiety disorder and MDD compared to offspring of non-psychiatric controls (ORs range from 1.96 to 8.69); and (3) offspring of parents with anxiety only, anxiety plus MDD, and MDD only have similar odds of having anxiety and depressive disorders but significantly higher odds than offspring of parents without disorder. Results suggest that parental anxiety disorders confer significant risk for anxiety and depression in offspring. Additional studies are needed to examine whether there are differences among specific parental anxiety disorders.

This retrospective study assessed the correlations between various types of stressful life events (SLE) and suicidal adolescents and young adults with major depressive disorder (MDD;22), borderline personality disorder (BPD;18), and nonsuicidal adolescents and young adults with MDD (20) and BPD (20). A community control group of 40 participants was also evaluated. The measurements used were Life Events Checklist, Childhood Sexual Abuse Questionnaire, Suicide Risk Scale, and Beck Depression Inventory. Suicidal participants experienced a greater number of total lifetime negative events compared with nonsuicidal participants, irrespective of diagnosis, including a greater amount of negative life events in the year before the suicide attempt compared with the year before referral in the nonsuicidal group. Participants with MDD reported more lifetime negative events than participants with BPD. Suicidal adolescents did not have more lifetime death-related SLE than nonsuicidal adolescents, but MDD adolescents experienced more lifetime death-related SLE than BPD adolescents. Suicidal BPD participants reported more lifetime sex abuse-related SLE compared with nonsuicidal BPD participants. The complexity of the relationships between SLE and the interplay of both suicidality and underlying psychopathology is discussed with the relevant treatment implications.

Limited evidence suggests that depression is associated with poorer outcomes in behavioral weight loss programs; however, people with major depression are typically excluded from weight loss intervention trials. This study examined the effect of depression on women's participation and weight loss in behavioral treatment. Non-treatment seeking obese women over 40 years of age with major depressive disorder (MDD, n = 65) and without MDD (n = 125) were recruited into a 26-session group intervention. Primary analyses compared participants' mean weight change from baseline to 6 and 12 months; at 6 months, women with MDD lost a mean of 3.8 kg vs 4.3 kg for women without MDD (t = 0.54, p = .59). At 12 months, women with MDD lost 3.0 kg and women without MDD lost 3.6 kg (t = 0.44, p =.66). Women who attended at least 12 treatment sessions lost more weight than women who attended fewer sessions, regardless of depression status (ie, there was no significant interaction between depression and session attendance). Results suggest that depression should not be an exclusion criterion for weight loss intervention programs.

In everyday life, we often estimate rather than know. It was the goal of this study to assess the effect of depressed mood on cognitive estimation in old age. Cognitive estimation was performed in 44 subjects with major depressive disorder (MDD; DSM-IV) and 48 age-matched healthy subjects (HS). Severity of depressive symptoms was rated with the Montgomery-Asberg Depression Rating Scale (MADRS, mean=18.6+/-S.D. 4.85). Estimation tasks comprised the dimensions length (coin diameter), weight (pile of paper), quantity (number of marbles in a glass jar), and time (estimation of time it takes for a marble to roll down a marble track both before and after having observed it). Other than the procedure followed in previous tests on cognitive estimation, the tasks were performed by observing objects rather than pictures thereof. MDD patients overestimated time (before and after observation) and underestimated quantity. Cognitive estimation was not correlated to measures of frontal functioning or semantic knowledge. We conclude that MDD patients in old age are impaired to some extent in cognitive estimation and in the ability to correct themselves, deficits that are likely to affect the performance of everyday activities.
