Level of selected exponents of the kynurenine pathway in patients diagnosed with depression and selected cancers

Altered immune system activity is one of the common pathomechanisms of depressive disorders and cancer. The aim of this study is to evaluate level of selected elements of the kynurenine pathway in groups of depressed and oncological patients. The study included 156 individuals, aged 19–65 years (M = 43.46, SD = 13.99), divided into three groups, namely depressive disorders (DD), oncology patients (OG), and a comparison group of healthy subjects (CG). A sociodemographic questionnaire and the Hamilton Depression Rating Scale (HDRS) were used in the study to assess the intensity of depressive symptoms. Level of TDO2, L-KYN, HK, AA and QA was significantly higher in patients from OG and DD groups than in the comparison group. TDO2 level in the OG group was positively correlated with the severity of depressive symptoms. When the OG and DD groups were analyzed together, level of TDO2, 3-HKYN, AA, QA correlated positively with the severity of depressive symptoms. Thus, kynurenine pathway might play an integral role in the pathogenesis of depression.

HRV changes in young adults with depression.

Depression is a common and debilitant mental health disorder that is very common among young adults of the age group of 18-25 years. There is evidence that autonomic nervous system dysfunction associated with depression may play an important role in cardiovascular disease among patients with depression. HRV that is used to assess ANS function is found to be altered in depression. Since the HRV findings associated with depression remain inconsistent, this study is aimed to find HRV changes associated with depression so that the use of HRV as a diagnostic tool for depression can be validated. A total of 42 newly diagnosed patients of depression of the age group (18-26) years and 89 non-depressed volunteers matched for age, BMI and sex proportions were included in the study. Heart rate variability was recorded using five-minute stationary RR interval of Lead II by 4-channel Power Lab System (AD Instrument Ltd). HRV findings are summarized into Time-Domain parameters, Frequency-Domain parameters and Non-Linear parameters. All HRV parameters are significantly reduced and the LF/HF ratio is significantly raised (P < 0.05) in the group of depressive patients when compared to the group of healthy controls. The reduction of HRV parameters (SDRR, RMSSD, Total Power, SD1 and SD2) in the group of patients with depression is found to be highly significant (P < 0.0001). The findings of our study suggest that depression may be associated with alterations in ANS activities, which contribute to an increased risk of cardiovascular disease. Thus, HRV can serve as a potential bio-marker for depression.

Serum Levels of Zinc, Albumin, Interleukin-6 and CRP in Patients with Unipolar and Bipolar Depression: Cross Sectional Study.

Unipolar (UD) and bipolar depression (BDD) show a high degree of similarity in clinical presentations, which complicates the differential diagnosis of these disorders. The aim of this study was to investigate the serum levels of interleukin 6 (IL-6), C-reactive protein (CRP), albumin (Alb), and zinc (Zn) in patients with UD, BDD, and healthy controls (HC). A total of 211 samples were collected: 131 patient samples (65 UD and 68 BDD) and 80 HC. The Montgomery-Asberg Depression Rating Scale (MADRS), along with the Hamilton Depression Rating Scale (HAMD-17), were administered to patient groups to evaluate symptoms. A cross-sectional study was performed to analyse the serum levels of IL-6, CRP, albumin, and zinc. The concentration of CRP was determined using the immunoturbidimetry method, zinc using the colorimetric method, and albumin using the colorimetric method with bromocresol green on the Alinity c device. IL-6 cytokine concentration in serum samples was ascertained using a commercial enzyme immunoassay, ELISA. We found no significant differences in serum concentrations of zinc, albumin, CRP, and IL-6 between the groups of patients with unipolar and bipolar depression. There was a significant statistical difference (p < 0.001) between serum levels of all investigated parameters in both groups of depressed patients in comparison with HC. Furthermore, correlations with specific items on HAMD-17; (namely, hypochondrias, work and activities, somatic symptoms-general, and weight loss) and on MADRS (concentration difficulties, lassitude) were observed in both patient groups. These findings confirm the presence of low-grade inflammation in depression, thus adding better insight into the inflammation hypothesis directed to explain the aetiology of depressive disorders. Our results do not indicate potential biomarkers for distinguishing between unipolar and bipolar depression.

Effects of ebselen addition on emotional processing and brain neurochemistry in depressed patients unresponsive to antidepressant medication

Lithium is an effective augmenting agent for depressed patients with inadequate response to standard antidepressant therapy, but numerous adverse effects limit its use. We previously reported that a lithium-mimetic agent, ebselen, promoted a positive emotional bias—an indicator of potential antidepressant activity in healthy participants. We therefore aimed to investigate the effects of short-term ebselen treatment on emotional processing and brain neurochemistry in depressed patients with inadequate response to standard antidepressants. We conducted a double-blind, placebo-controlled 7-day experimental medicine study in 51 patients with major depressive disorder who were currently taking antidepressants but had an inadequate response to treatment. Participants received either ebselen 600 mg twice daily for seven days or identical matching placebo. An emotional testing battery, magnetic resonance spectroscopy and depression and anxiety rating scales were conducted at baseline and after seven days of treatment. Ebselen did not increase the recognition of positive facial expressions in the depressed patient group. However, ebselen increased the response bias towards fear emotion in the signal detection measurement. In the anterior cingulate cortex, ebselen significantly reduced the concentrations of inositol and Glx (glutamate+glutamine). We found no significant differences in depression and anxiety rating scales between visits. Our study did not find any positive shift in emotional bias in depressed patients with an inadequate response to antidepressant medication. We confirmed the ability of ebselen to lower inositol and Glx in the anterior cingulate cortex. These latter effects are probably mediated through inhibition of inositol monophosphatase and glutaminase respectively.

DNA methylation signatures support the role of neutrophils and monocytes in depression

IntroductionResearch repeatedly linked inflammation with major depressive disorder (MDD). The presence of an inflammatory subtype of depression is supported by molecular findings as well as imaging reports. We investigated the cell type composition estimated by using epigenome-wide DNA methylation markers in a sample of depressed individuals showing high or low inflammation levels measured by hsCRP. We aimed to understand the connection between depression and inflammation, specifically differences in cell type compositions between high and low inflammation groups at baseline.Objectives119 individuals with MDD were included for this analysis. Following quality control procedures, 113 participants were included in the analysis (Mage= 47 years, 57.98% women). The sample consisted of 37 individuals with high hsCRP (hsCRP &gt; 1.5, Mage=45, MhsCRP=8.2, MMADRS=28, 70% women) and 76 individuals with low hsCRP (hsCRP &lt; 1.5, Mage= 44, MhsCRP=0.99, MMADRS=28, 49% women).MethodsThe Illumina Infinium MethylationEPIC 850k BeadChip was used for analyzing whole blood derived DNA. Data processing and cell type estimation was conducted using the RnBeads package. We applied the Houseman method to estimate cell type composition through epigenome-wide DNA methylation signatures, resulting in six cell types: neutrophils, natural killer cells, B cells, CD4+ T cells, CD8+ T cells and monocytes. Comparisons between both groups were tested using ANOVA.ResultsHigh and low hsCRP groups were compared for each of the six cell types estimated. A statistically significant difference was seen for monocytes (p=0.0316) and a trend for neutrophils (p=0.0742). The mean values for neutrophils in patients without inflammation were found to be 60%, while in patients with inflammation, it was 63%. For monocytes, the mean values for patients without inflammation and those with inflammation were 10% and 9.4%, respectively, with a smaller range (4.5%-14.3%) for individuals with inflammation as compared to patients without inflammation (5.3%-20.7%). None of the other four cell types showed a statistically significant difference.Conclusions We identified differences in the cell type composition between groups of depressed patients with high versus low inflammation. These results align with the existing body of knowledge reported in established academic literature. Our study emphasizes the role of specific cells like neutrophils and monocytes in inflammation and depression. These findings offer valuable insights for improving depression treatment strategies as inflammation state may be relevant for treatment response. We also show the merit of DNA methylation signatures for the profiling of patients’ inflammation status, i.e., immunomethylomics.Disclosure of InterestNone Declared

Comparison of the Neurological and Neuropsychological Functions Within Depressed Patients with and Without Suicidal Thoughts

Objectives: This study was designed and conducted to compare the neurological and neuropsychological functions of depressed patients with and without suicidal thoughts. Methods: This research is a case-comparative study. A group of depressed patients visited NAJA Imam Sajjad Hospital between early August and late October 2016. According to the Morgan table, 66 individuals (33 with suicidal thoughts and 33 without) were selected for comparison with controlled variables in this examination. The Beck Depression Inventory (BDI), Neurological Evaluation Scale, and Wechsler Memory Scale (for neuropsychological function) were administered to all the participants. Data were analyzed using one-way analysis of variance (ANOVA), Scheffe follow-up test, and SPSS version 22 software. Results: The findings indicated that the group of depressed patients with suicidal thoughts showed poorer scores in neurological functions compared to the control group (P = 0.01). Furthermore, the control group scored higher than the depressed group with suicidal thoughts on the Wechsler Memory Scale (P = 0.05). Conclusions: The results suggest that depressed patients with suicidal thoughts exhibit worse performance in both neurological and neuropsychological functions compared to the non-suicidal group.

Subtypes of major depressive disorders and objectively measured physical activity and sedentary behaviors in the community

BackgroundLack of physical activity (PA) and high sedentary behavior (SB) may enhance mental health problems, including depression, and are associated with increased mortality. Aside from a large body of research on major depressive disorder (MDD) assessed as an entity and either PA or SB, few studies have examined associations among subtypes of MDD and both PA and SB simultaneously derived from wrist-worn accelerometers. Accordingly, our aim was to explore the associations among MDD subtypes (atypical, melancholic, combined atypical-melancholic and unspecified) and four actigraphy-derived behaviors combining the levels of PA and SB. MethodsThe sample stemmed from CoLaus|PsyCoLaus, a population-based cohort study, consisting of 2375 participants (55.1% women; mean age: 62.4 years) who wore an accelorometer for 14 days after a physical exam and subsequently completed a semi-structured psychiatric interview. Activity behaviors were defined according to the combination of the levels of moderate-to-vigorous intensity PA and SB. Associations of remitted MDD subtypes, current MDD and physical inactivity behaviors were assessed using multinomial logistic regression, adjusted for socio-demographic characteristics, a history of anxiety, alcohol and drug use disorders and cardiovascular risk factors. ResultsIn the fully adjusted model, participants with the remitted combined atypical-melancholic subtype had a higher risk of being more physically inactive. ConclusionsOur findings suggest that low PA and high SB are not restricted to the duration of depressive episodes in people with atypical and melancholic episodes. The lack of PA and high SB in this group of depressive patients exposes them to an additional long-term cardiovascular risk and measures to increase PA may be particularly fruitful in this MDD subgroup.

Objective Depression Detection Using EEG and Eye Movement Signals Induced by Oil Paintings.

Depression is a mental disorder characterized by persistent sadness and loss of interest, which has become one of the leading causes of disability worldwide. There are currently no objective diagnostic standards for depression in clinical practice. Previous studies have shown that depression causes both brain abnormalities and behavioral disorders. In this study, both electroencephalography (EEG) and eye movement signals were used to objectively detect depression. By presenting 40 carefully selected oil paintings-20 positive and 20 negative-as stimuli, we were able to successfully evoke emotions in 48 depressed patients (DPs) and 40 healthy controls (HCs) from three centers. We then used Transformer, a deep learning model, to conduct emotion recognition and depression detection. The experimental results demonstrate that: a) Transformer achieves the best accuracies of 89.21% and 92.19% in emotion recognition and depression detection, respectively; b) The HC group has higher accuracies than the DP group in emotion recognition for both subject-dependent and subject-independent experiments; c) The neural pattern differences do exist between DPs and HCs, and we find the consistent asymmetry of the neural patterns in DPs; d) For depression detection, using single oil painting achieves the best accuracies, and using negative oil paintings has higher accuracies than using positive oil paintings. These findings suggest that EEG and eye movement signals induced by oil paintings can be used to objectively identify depression.

Effectiveness of Repetitive Transcranial Magnetic Stimulation in the Treatment of Depression in the Elderly: A Retrospective Natural Analysis.

Depression in the elderly is an understudied condition. Psychopharmacological and psychotherapeutic approaches suffer from specific difficulties with this patient group. Brain stimulation techniques such as repetitive transcranial magnetic stimulation (rTMS) offer a therapeutic alternative. rTMS remains understudied in this age group when compared with younger patients. A cohort of 505 patients with depression was analyzed in retrospect concerning their response to rTMS treatment. A total of 15.5% were 60 years old or older, defined as the elderly group of depressed patients. The majority of these were treated with high-frequency protocols over the left dorsolateral prefrontal cortex (DLPFC). For group comparisons, we used Student t-tests or chi-square-tests, depending on the scales of measurement. As measures for effect size, we used Cohen's d for the relative and absolute change in the HDRS total score. Groups did not differ significantly with respect to baseline depression severity or treatment parameters. In the group of elderly patients, a higher number of females were present. Groups did not differ significantly with respect to treatment efficacy, as indicated by the absolute and relative changes in the HDRS-21 sum score. Elderly patients tended to take higher numbers of mood stabilizers. Elderly patients showed a significantly superior reduction for the item "appetite" and a superior reduction tending towards significance for the item "work and interests". Antidepressant rTMS treatment showed comparable efficacy for patients above 60 years to that in younger patients. Differences between the age groups concerning amelioration of distinct HDRS single items deserve further investigation.

The contribution of the cingulate cortex: treating depressive symptoms in first-episode drug naïve schizophrenia.

Our previous study has shown the cingulate cortex abnormalities in first-episode drug naïve (FEDN) schizophrenia patients with comorbid depressive symptoms. However, it remains largely unknown whether antipsychotics may induce morphometric change in cingulate cortex and its relationship with depressive symptoms. The purpose of this study was to further clarify the important role of cingulate cortex in the treatment on depressive symptoms in FEDN schizophrenia patients. In this study, 42 FEDN schizophrenia patients were assigned into depressed patients group (DP, n=24) and non-depressed patients group (NDP, n=18) measured by the 24-item Hamilton Depression Rating Scale (HAMD). Clinical assessments and anatomical images were obtained from all patients before and after 12-week treatment with risperidone. Although risperidone alleviated psychotic symptoms in all patients, depressive symptoms were decreased only in DP. Significant group by time interaction effects were found in the right rostral anterior cingulate cortex (rACC) and other subcortical regions in the left hemisphere. After risperidone treatment, the right rACC were increased in DP. Further, the increasing volume of right rACC was negatively associated with improvement in depressive symptoms. These findings suggested that the abnormality of the rACC is the typical characteristics in schizophrenia with depressive symptoms. It's likely key region contributing to the neural mechanisms underlying the effects of risperidone treatment on depressive symptoms in schizophrenia.

Urine 3-Nitrotyrosine and Serum HDL as Potential Biomarkers of Depression

Depression (MDD) is a leading psychiatric entity worldwide, with a high impact on individual life and public health. In recent years, efforts have been made to elucidate its biological underpinnings. MDD biomarker research provides promise for a better understanding of the biochemical processes involved in its pathogenesis. Oxidative and nitrosative stress (O&NS) and lipid disturbances are reported as major factors favoring the occurrence of depression. A total of 29 patients with MDD and 30 healthy volunteers were examined using the Hamilton Depression Scale (HAM-D), the Hamilton Anxiety Scale (HAM-A), and the Beck Depression Inventory (BDI). Blood and urine were collected to search for potential MDD biomarkers. O&NS parameters and β-amyloid were assessed in the urine, while cholesterol fractions were assessed in the blood. The group of depressed patients was characterized by higher concentrations of urine superoxide dismutase (SOD), 3-nitrotyrosine (3-NT), catalase (CAT), reduced glutathione (GSH), tryptophan (TRY), and serum triglycerides (TGA), along with lower levels of serum high-density lipoprotein (HDL). Elevated urine 3-NT and decreased serum HDL, considered together, were found to have the greatest potential as markers of depression. The study supports the importance of oxidative stress and cholesterol disturbances in MDD. Further research is required to assess their clinical usefulness as markers.

Exploring the Correlation between Changes in Gut Microbial Community Diversity and Depression in Human Populations.

Depression, also known as depressive disorder, is a group of psychosomatic affective disorders characterized by persistent and significantly depressed mood, delayed thinking, and cognitive impairment. The aim of this study was to explore the correlation between changes in gut microbial community diversity and depression to provide data on new strategies for the prevention and treatment of depression. In this study, we separated participants into a group of depressed patients and a healthy comparison group. We analyzed the gut microbial community structure of depressed patients and healthy comparisons using second-generation sequencing of the bacterial 16S RNA gene. There were significant differences in the gut microflora structure between patients with depression and healthy individuals. The gut flora alpha diversity index was significantly reduced in patients with depression compared to that in the healthy population. At the species level, the relative abundance of Coprococcus catus and Bacteroides barnesiae was significantly lower in the depressed group than that in the control group. The development of depression may be associated with a decrease in beneficial gut bacteria.

The AREDOC project and its implications for the definition and measurement of the bipolar disorders: A summary report

Judging that the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria for defining mania/hypomania (and thus bipolar I/II disorders, respectively) would benefit from review, we formed an expert taskforce to derive modified criteria for consideration. The aim of this paper is to summarise the component stages and detail the final recommended criteria. We first sought taskforce members' views on the Diagnostic and Statistical Manual of Mental Disorders criteria and how they might be modified. Next, members recruited patients with a bipolar I or II disorder, and who were asked to judge new definitional options and complete a symptom checklist to determine the most differentiating items. The latter task was also completed by a small comparison group of unipolar depressed patients to determine the mood state items that best differentiate unipolar from bipolar subjects. Subsequent reports overviewed analyses arguing for bipolar I and II as being categorically distinct and generated empirically derived diagnostic criteria. Alternatives to all the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria were generated. Modifications included recognising that impairment is not a necessary criterion, removing hospitalisation as automatically assigning bipolar I status, adding an irritable/angry symptom construct to the symptom list, deleting a mandatory duration period for manic/hypomanic episodes, and requiring a greater number of affirmed symptoms for a bipolar diagnosis to manage the risk of overdiagnosis. Granular symptom criteria were identified by analyses and constructed to assist clinician assessment. A potential bipolar screening measure was developed with analyses showing that it could clearly distinguish bipolar versus unipolar status, whether symptom items were assigned as having equal status or weighted by their quantified diagnostic contribution. While requiring further validation, we suggest that the revised criteria overcome several current Diagnostic and Statistical Manual of Mental Disorders (5th ed.) limitations to defining and differentiating the two bipolar sub-types, while still respecting and preserving the Diagnostic and Statistical Manual of Mental Disorders template. It will be necessary to determine whether the bipolar screening measure has superiority to currently accepted measures.

Treatment of the depressive patients at clinical high-risk for psychosis

IntroductionAt present, there is no universally approach to treating patients at clinical high-risk for psychosis (CHR) without comorbid mental disorders. However, if there are revealed depressive symptoms, proper treatment becomes necessary.ObjectivesEstablish pharmacological classes and doses of drugs that have proved effective in treating depressive patients at CHR.MethodsA comparative study of pharmacological classes and doses of drugs was carried out, showing the effectiveness in treatment of 219 depressive patients at CHR and 52 depressive patients without CHR. The treatment effectiveness was carried out on the reduction of depression symptoms on the HDRS scale, and the CHR symptoms on the SOPS scale.ResultsA significant reduction of depression symptoms was achieved in the group of depressive patients with and without CHR on the HDRS scale (67.9% and 76.6% respectively). The reductions of the CHR symptoms were 46.1% and 53.3% respectively. There were differences between the severity of depression symptoms and CHR symptoms before and after the treatment. Both groups used antidepressants followed by the prescription of antipsychotics to increase the effectiveness of the therapy. No difference was found in the doses of antidepressants for the fluoxetine equivalent (46.0 vs 42.6 mg per day, p 0.05) and some differences were found for the average effective doses of antipsychotics for the chlorpromazine equivalent (385.4 vs 230.8 mg per day, p 0.05).ConclusionsThe same pharmacological classes are used for the treatment of young depressive patients with and without CHR, but the former have significantly higher doses of antipsychotics.DisclosureNo significant relationships.

Resistance or pseudo-resistance?

IntroductionTreatment-Resistant Depression continues to represent a great challenge for clinicians.ObjectivesWe investigated patients with history of resistance, assessing prognostic factors, response to treatments, and remission over time.MethodsWe recruited 202 unipolar and bipolar depressed inpatients. According to anamnestic backgrounds, patients were assigned to: A) Non-resistant : responders, with no characteristics of resistance in the current episode. B) Resistant: resistant to two antidepressant trials of adequate doses and duration. C) Pseudo-resistant : non-responders, not classifiable as Resistant because of inadequate trials. During hospitalization, patients were treated by clinical judgment, following a rehabilitation program.Results Table 1Non-resistant (111)Resistant (54)Pseudo-resistant (35)p-valueAge59.1±11.963.0±12.657.0±11.30.036*Episodes of illness3.8±2.14.0±1.93.0±1.80.036*Personality disorders27.0%18.9%48.6%0.009**Therapies:0.014**SSRI62.4%40.4%69.7%SNRI19.8%42.3%15.1%TCA17.8%17.3%15.1%Augmentation24.3%38.9%17.1%0.05**Remission76.5%59.5%81.2%CvsB:0.045** CvsA:0.587**On the day of admission, non-responders were 44.5% of the sample, but 39.3% of them did not meet the Resistant criteria, defining the Pseudo-resistant group. Pseudo-resistant differed from others by younger age, fewer illness episodes, higher rate of personality disorders, and different therapies during hospitalization [Fig.1,2,3]. Pseudo-resistant remission rate, significantly greater than Resistant one, was comparable to Non-resistant [Tab.1]. *Kruskal-Wallis Test **Chi-Squared TestConclusionsThis study outlines a new group of depressed patients that, apparently drug-resistant, displays the same outcome as responders when treated with first-line drugs during hospitalization, certainly taking benefit from the psychoeducational program. Quick recognition of these patients could be crucial to giving optimal care.DisclosureNo significant relationships.

Duration of therapy and treatment compliance of depressive patients at clinical high-risk for psychosis

IntroductionIt is known that early withdrawal can lead to a worsening of mental health. This is particularly relevant for depressive patients with clinical high-risk for psychosis (CHR) for whom the recommended duration of treatment has not been established.ObjectivesAnalyze the actual treatment duration of depressive patients at CHR after their discharge from hospital and compare it with the group of depressive patients without CHR.MethodsA comparative study of 124 depressive patients with CHR and 27 depressive patients without CHR was conducted within a year after discharge from hospital to assess the therapy duration and treatment compliance.ResultsWithin a year after discharge only 12.1% depressive patients with CHR and 29.6% ones without CHR continued to receive the therapy. The average duration of treatment after discharge was 7.4 months in the first group and 11.7 months in the second group. The majority of patients stopped treatment for the following reasons (in descending order of importance): lack of awareness of their mental condition (51.9% vs 40.3%), side effects (38.7% vs 11.1%), and negative attitudes towards the treatment on the part of patients’ immediate family members (8.9% vs 7.4%).ConclusionsIt has been found out that depressive patients with CHR are less likely to follow medical prescriptions than ones without CHR, they are more likely to have the lack of awareness of their mental condition, they are more likely to have side effects of the therapy. These findings require the development of a universal approach to the treatment of such patients after discharge from hospital.DisclosureNo significant relationships.

Is the JAK-STAT Signaling Pathway Involved in the Pathogenesis of Depression?

(1) Background: Only 60–70% of depressed patients respond to standard antidepressant treatments. Hence, it is essential to search for new, effective and safe therapies for unmet clinical needs of treatment-resistant depression (TRD). Agents targeting the components of the JAK-STAT signaling pathway have been shown to be relevant in immunology and are commonly used in the treatment of many hematological, rheumatological and dermatological diseases. The aim of this study was to investigate the role of elements of the JAK-STAT signaling pathway in the etiopathogenesis of depressive disorders. (2) Methods: A total of 290 subjects took part in the study (190 depressed patients, 100 healthy controls). Sociodemographic data were collected. The severity of depressive symptoms was assessed using the Hamilton Depression Rating Scale (HDRS). The gene expression at the mRNA protein levels of JAK (JAK1-JAK3) and STAT (STAT1-STAT5) was assessed by using RT-PCR and ELISA. (3) Results: Increased expression of JAK3 and decreased expression of STAT1 were observed in the group of depressed patients. (4) Conclusions: Further studies are necessary to determine whether moderation of the JAK-STAT signaling pathways is involved in the treatment of depression.

Impaired emotional intelligence is related to symptoms severity and suicidal attempts in depression.

Few studies demonstrated the impairment of perceived emotional intelligence 'EI' among depressed patients. This study aimed to assess the perceived EI in a group of depressed patients, and its association with different clinical characteristics. Forty-five patients diagnosed with depression were assessed by the Hamilton Depression Rating Scale and compared to 45 controls that were assessed by the Arabic version of General Health Questionnaire to exclude Psychiatric disorders. The Arabic version of Trait Meta-Mood Scale (TMMS) is used to evaluate EI in both groups. Patients with depression showed significantly lower EI scores in the three parts of TMMS (repair, clarity and attention) compared to the controls (p < .001). Patients showed significant difference in clarity subscale (p = .005) and attention regarding severity of depression (p < .001). Clarity of feelings was significantly higher in patients who suffered more than two episodes (p = .012). Depressive patients with suicidal attempts showed significantly lower scores of repair (p = .044) and attention (p = .016) subscales. There were no significant differences of TMMS subscales between patients with and without suicidal ideation, sleep disturbance and somatic symptoms. The current study demonstrates impaired perceived EI among patients with depression that is correlated with symptom severity and suicidal attempts.

Impact of depressive disorders on clinical outcomes in patients with chronic heart failure.

IntroductionTo date, there are no literature reports of research investigating the relationship between depression and chronic heart failure (CHF) in relation to selected nutritional, cardiac and laboratory parameters.AimTo compare CHF parameters in relation to nutritional and laboratory parameters between depressed and non-depressed patients.Material and methodsWe enrolled 94 CHF individuals from Lubelskie Voivodeship to assess depression prevalence and to compare values of cardiac, laboratory and nutritional parameters between depressed and non-depressed patients.ResultsDepression was diagnosed in 66 (70.2%) individuals. We noted significantly lower ejection fraction (EF) (EF%) in the group of depressive patients compared to disease-free individuals (mean EF%: 42 ±12 and 49 ±9; p = 0.030) and worse outcomes in NYHA examination (p < 0.001). Depressed patients had lower body weight (p = 0.023), body mass index (BMI) (p = 0.044), serum albumin concentration (p = 0.015), and hemoglobin concentration (p = 0.042) and an elevated level of C-reactive protein (CRP) (p = 0.025) in comparison to the non-depressed group. The moderate or severely depressed group had a lower level of EF% (p = 0.019) and higher left anterior descending artery (LAD) (p = 0.040) compared with the group suffering from mild depression. We observed greater susceptibility to develop cachexia in patients diagnosed as moderately or severely depressed (p = 0.030). Moreover, in the mentioned group of patients, lower values of body weight (p = 0.037), fat-free mass (FFM) (p = 0.022) and hemoglobin concentration (p = 0.007) were found. Moreover, an inverse correlation between Beck Depression Inventory (BDI) score and EF% (r = –0.371; p = 0.017) was recorded.ConclusionsDepression in CHF patients is associated with worse cardiac, laboratory and nutritional outcomes. Unfavorable clinical characteristics of CHF patients are related to depression severity.

Anticipation of High-Sensitivity C-Reactive Protein Effect on Post Myocardial Infarction Depression Disorder

Background: The natural history of acute myocardial infarction (AMI) as the most prevalent public health issue in Iran has changed with the introduction of novel therapeutic strategies that have reduced its mortality significantly. Major depressive disorder (MDD) is a prevalent and disabling psychiatric disorder and frequently co-exist with AMI. There are proposed pathophysiological links between the two diseases among which inflammation is the most important. With more patients surviving a myocardial infarction (MI) event, post-MI depression has become an important determinant of disability and mortality. Materials and Methods: In this study we defined a 1-month post-MI depressive scale of 200 patients using Beck’s inventory questionnaire II and measured serum high Sensitivity C-Reactive Protein (hs-CRP) and carotid intima-media thickness (CIMT) to look for the association between inflammatory state and atherosclerosis in different depression score categories. Results: Minimum and maximum Beck scores were 1 and 43, respectively with a mean of 13±8. The mean CIMT was 0.77±0.26 mm. Serum hs-CRP level was measured with a mean of 1.51±1.6 mg/L. According to BDI-II scores, 44.2% of patients 1-month post-MI suffered from more than mild depression. Being affected was not correlated with either the level of hs-CRP or CIMT. Nearly 44 percent of patients suffered more than mild depression. There was a negative association between serum hs-CRP level and CIMT as a measure of atherosclerosis in groups of depressed versus non-depressed patients. This may indicate that the extent of atherosclerosis is not correlated with the inflammatory state after MI in depressed versus non-depressed patients. Conclusions: The results of this study indicate that the extent of atherosclerosis is not correlated with the inflammatory state after MI in depressed versus non-depressed patients. Nonetheless, the prognostic indications of increased hs-CRP and depression after AMI remains to be investigated further. [GMJ.2021;10:e1512]
