Abstract Objectives Major depressive disorder (MDD) is a distressing condition characterized by persistent low mood, loss of interest in daily activities. Researchers consider several biological, psycho-social, and genetic factors are involved in depression. The present study aimed to investigate the serum levels of monocyte chemoattractant protein-1 (MCP-1) in MDD patients to explore its role in depression. Methods This case-control study recruited 114 MDD patients and 106 healthy controls (HCs) matched by age and gender. A specialized psychiatrist diagnosed the cases and evaluated the controls based on the diagnostic and statistical manual for mental disorders, 5th edition. We quantified serum MCP-1 levels using commercially available enzyme-linked immune sorbent assay kits. Also, we applied the Hamilton depression rating scale (Ham-D) to measure the severity of depression. Results We observed the decreased levels of serum MCP-1 in MDD patients compared to HCs. Also, we obtained a significant negative correlation between serum MCP-1 levels and Ham-D scores. Moreover, female MDD patients with higher Ham-D scores exhibited lower serum MCP-1 levels. The receiver operating characteristic analysis demonstrated the good diagnostic value of MCP-1 with the area under the curve at 0.837. Conclusions The depression-related alteration of serum MCP-1 may be more complicated than the current assumption and depends on the characteristics of the individual patients. Our study suggests that the serum MCP-1 levels might involve in the pathophysiology and mechanism of MDD. The present findings, along with the diagnostic evaluation, might be used to evaluate depressive patients.

AbstractMajor depressive disorder (MDD) is a distressing condition characterized by persistent low mood, loss of interest in daily activities. Many biological, psycho-social, and genetic factors are thought to be involved with depression. The present study aimed to investigate the serum levels of monocyte chemoattractant protein-1 (MCP-1) in MDD patients to explore its role in the development of depression. This case-control study recruited 114 MDD patients and 106 healthy controls (HCs) matched by age and gender. A specialized psychiatrist diagnosed the cases and evaluated the controls based on the diagnostic and statistical manual for mental disorders, 5th edition. The serum MCP-1 levels were quantified by commercially available enzyme-linked immune sorbent assay kits. The Hamilton depression rating scale (Ham-D) was applied to measure the severity of depression. We observed the decreased levels of serum MCP-1 in MDD patients compared to HCs. A significant negative correlation was obtained between serum MCP-1 levels and Ham-D scores. Also, female MDD patients with higher Ham-D scores exhibited lower serum MCP-1 levels. The receiver operating characteristic analysis demonstrated the good diagnostic value of MCP-1 with the area under the curve at 0.837. The depression-related alteration of serum MCP-1 may be more complicated than the current assumption and depends on the characteristics of the individual patients. Our study suggests that the serum MCP-1 levels might be involved in the pathophysiology and mechanism of MDD.

Objectives: Major depressive disorder is diagnosed on the basis of patient’s self-reported experiences, behavior reported by relatives, and a mental status examination, and yet we do not have any reliable biomarker for this. Mood-regulating pathways are affected by oxidative injury to lipids and cortisol is released into the blood due to stimulation of corticotrophin receptors in the adrenal cortex. Here, we aimed to determine serum levels of malondialdehyde and cortisol in major depressive disorder patients and controls. Methods: We collected blood samples from 247 major depressive disorder patients and 248 controls. Serum levels of malondialdehyde and cortisol were measured by ultraviolet spectrophotometry and enzyme-linked immunosorbent assay kit, respectively. Results: We found malondialdehyde levels were significantly higher in patients than controls, with mean ± standard deviation at 4.49 ± 1.37 and 2.87 ± 0.82 µmol/L, respectively, p < 0.001. Cortisol levels were also found significantly higher in patients than controls, with mean ± SD at 19.22 ± 1.64 and 17.37 ± 1.34 µg/dL, respectively, p < 0.001. Significant negative correlation was observed between serum levels of malondialdehyde and cortisol in patients ( r =−0.170, p = 0.021). Receiver operating characteristic analysis showed good diagnostic value for malondialdehyde and cortisol, with the area under the curve at 0.853 and 0.819, respectively. Conclusion: The present study suggests that increased serum levels of malondialdehyde and cortisol are strongly associated with major depressive disorder. We believe elevations of malondialdehyde and cortisol in serum level arise independently and they could serve as biomarkers for major depressive disorder.

BackgroundThe predictive value of early functional improvement for treatment success at week 8 was assessed in a pooled analysis in patients with major depressive disorder (MDD).MethodsData were pooled from 7 double-blind studies in adult patients with MDD randomly assigned to desvenlafaxine 50 mg/d or placebo. Four levels of treatment success were determined at week 8 for patients with baseline Sheehan Disability Scale (SDS) score > 12 (N = 2156): functional response (SDS ≤12 and ≥50% improvement in SDS), functional/depression response (SDS ≤12 and ≥50% improvement in both SDS and 17-item Hamilton Rating Scale for Depression [HAM-D17] score), functional remission (SDS < 7), and functional/depression remission (SDS < 7 and HAM-D17 ≤7). Week 2 improvement in SDS was evaluated as a predictor of later functional response/remission using receiver operating characteristic analysis. Odds ratios (ORs) of the predictability of improvement thresholds were computed from a logistic regression model.ResultsThe proportion of patients achieving each level of treatment success was significantly greater for patients treated with desvenlafaxine (40%, 32%, 23%, 15%, respectively) vs placebo (31%, 22%, 17%, 10%; all P ≤ 0.002). Early change in SDS was a highly significant predictor of functional response/remission (ORs, 0.958–0.970; all P < 0.0001).DiscussionPatients’ early functional response to desvenlafaxine 50 mg/d is predictive of treatment success.

Abstract Objectives Mental disorders have a large impact on death by suicide. Hence, this study aims to determine the prevalence of suicidal behaviors among major depressive disorder (MDD) patients and the associated factors. Materials and Methods This cross-sectional analytical study was conducted among individuals aged 18 to 65 years, diagnosed with MDD in the Psychiatry Outpatient Department of a Tertiary Care Center, Puducherry during March to October 2019. Severity of depression was assessed using Hamilton Depression Rating Scale and Columbia-Suicide Severity Rating Scale was used to find the suicidal behaviors. Results For 166 participants in the study, mean (standard deviation) age was 40 (11) years and majority were females (76%). More than one-third (37%) had severe or very severe depression, and the prevalence of suicidal ideation, plan, and attempts were 83, 24, and 35%, respectively. After adjusting the covariates, the severity of depression and unemployment were significantly associated with suicidal attempts (adjusted prevalence ratios [aPR] = 11.4 and 1.9), and very severe depression was associated with suicidal ideation (aPR = 1.6). Among 140 individuals with suicidal ideation, 45 (32%) had an ideation frequency of 2 to 3 times/week, 69 (50%) had ideation for 1 hour, 36 (26%) could control ideation with little difficulty, and 12% had suicidal ideation mostly to end or stop their pain. Conclusion Suicidal ideation and attempts were significantly high in MDD patients, and the severity of depression was significantly associated with it. Early identification of high-risk suicidal behavior and implementation of effective preventive interventions are necessary to reduce death by suicide in these groups.

AbstractPatients with major depressive disorder (MDD) may be refractory to or have contraindications that preclude treatment with antidepressant pharmacotherapies. Alternative therapies such as repetitive transcranial magnetic stimulation (rTMS) continue to evolve, and include theta burst stimulation (TBS), which has advantages over conventional rTMS. The aim of this study was to identify and meta-analyze efficacy data from all randomized controlled trials (RCTs) investigating TBS as a treatment for MDD. Published reports of RCTs (January 1, 2010 to October 23, 2020) were identified via systematic searches in computerized databases, followed by review of individual reports for inclusion. Inclusion criteria included primary diagnosis of MDD ≥ 1 week duration of therapy with ≥10 sessions, and treatment with any form of TBS. The Cochrane GRADE methodology and PRISMA criteria were used for evaluation of individual trials. Data from ten RCTs were included, representing 667 patients. Of these, 8 RCTs compared TBS to sham treatment and one compared TBS to standard rTMS (i.e., high frequency stimulation over left dorsolateral prefrontal cortex [HFL]). Quality of evidence assessment yielded high confidence in the finding of TBS being superior to sham on response measured by the Hamilton Depression Rating Scale (HRSD) (RR = 2.4; 95% CI: 1.27 to 4.55; P = 0.007; I2 = 40%). Comparison of HRSD response rates for TBS versus rTMS produced no statistically significant difference (RR = 1.02; 95% CI: 0.85 to 1.23; P = 0.80; I2 = 0%). The incidence of adverse events between TBS and rTMS was not statistically different. The findings of a positive effect of TBS vs. sham, and noninferiority of TBS vs. standard HFL rTMS support the continued development of TBS to treat depression.

Background: Ketamine is central to one of the most rapidly growing areas of neuroscientific research into novel treatments for depression. Limited research has indicated that the psychedelic properties of ketamine may play a role in its antidepressant effects. Aim: The aim of the current study was to explore the psychedelic experiences and sustained impact of ketamine in major depressive disorder. Methods: In the current study, ketamine (0.44 mg/kg) was administered to 32 volunteers with major depressive disorder in a crossover design with the active-placebo remifentanil, in a magnetic resonance imaging (MRI) environment. The 11-dimension altered states of consciousness questionnaire and individual qualitative interviews were used to capture the acute psychedelic experience. The Montgomery-Asberg Depression Rating Scale and further interviewing explored lasting effects. The second qualitative interview took place ⩾3 weeks post-ketamine. Results: Greater antidepressant response (reduction in Montgomery-Asberg Depression Rating Scale at 24 h) correlated with the 11-dimension altered states of consciousness dimensions: spirituality, experience of unity, and insight. The first qualitative interview revealed that all participants experienced perceptual changes. Additional themes emerged including loss of control and emotional and mood changes. The final interview showed evidence of a psychedelic afterglow, and changes to perspective on life, people, and problems, as well as changes to how participants felt about their depression and treatments. Conclusions: The current study provides preliminary evidence for a role of the psychedelic experience and afterglow in ketamine’s antidepressant properties. Reflexive thematic analysis provided a wealth of information on participants’ experience of the study and demonstrated the psychedelic properties of ketamine are not fully captured by commonly used questionnaires.

BackgroundThe induction agent propofol is known to reduce electroconvulsive therapy (ECT) seizure duration. It is assumed that outcome from depression is adversely affected by this agent. This study compares propofol and methohexitone as induction agents for ECT.MethodIn a prospective, randomised, double-blind study 20 subjects with major depressive disorder (DSM-III-R criteria) received propofol or methohexitone anaesthesia. The Hamilton Depression Rating Scale and Beck Depression Inventory were used to assess depression before therapy, at every third treatment, and at the end of therapy. Seizure duration was measured using the cuff technique.ResultsMean seizure durations (P < 0.01) and mean total seizure duration (P < 0.01) were shorter in the propofol group. There was no difference in outcome.ConclusionsUse of propofol may not adversely affect outcome from depression and it is not necessarily contraindicated as an induction agent for ECT. Our results should be interpreted cautiously, and larger studies are needed.

IntroductionEfficacy of conventional repetitive transcranial magnetic stimulation (rTMS) in major depressive disorder (MDD) is limited. The authors report here on an alternative treatment using low energy synchronized TMS (sTMS) at the intrinsic frequency of subjects’ alpha electroencephalogram (EEG).ObjectivesEstablish efficacy and safety profile of sTMS in MDD.Aim(1)Examine the clinical effectiveness of sTMS.(2)Identify adverse effects associated with sTMS.MethodsFifty-two MDD subjects with 17-item Hamilton Depression Rating Scale (HAMD17) scores >17 were enrolled into a randomized, sham controlled, double-blind trial. Current medication remained unchanged during the trial. Depressive symptoms were evaluated by HAMD17 administered weekly.EEGs were recorded at baseline to determine the stimulus frequency and at week 4 to evaluate the physiological effect. sTMS was delivered through three 6000-G cylindrical neodymium magnets synchronously rotating at a rate equal to the subject's intrinsic alpha frequency.ResultsForty-five subjects completed at least 1 week of treatment and were evaluable. Those who received active treatment had superior clinical response to sham (t = 2.54, P = 0.01), where 55.2% in the active treatment group were clinical responders versus 12.5% in sham (X2 = 7.82, P = 0.005). No significant side effects were reported. The clinical improvement was correlated with the degree of EEG improvement (r = .46, P = 0.009).ConclusionsA therapeutic effect in MDD subjects can be achieved through administration of sTMS at the subject's alpha EEG frequency. Because of minimal side effects, this appears to be a safe and effective treatment option.
