The effect of major depressive disorder comorbidity on ischemia-modified albumin levels, a marker of oxidative stress, and antioxidant defense system in patients with obsessive compulsive disorder.

The aim of this study was to examine the levels of oxidant and antioxidant markers in patients with obsessive-compulsive disorder (OCD) and to investigate whether these levels change in the presence of major depressive disorder (MDD) comorbidity. This study was completed with 23 OCD patients with MDD comorbidity (OCD+MDD), 21 OCD patients without MDD comorbidity (OCD-MDD) and 21 healthy controls. Oxidative stress levels of the cases' were determined by ischemia modified albumin (IMA) and malondialdehyde (MDA) measurements and antioxidant levels were determined by superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) measurements. One-way analysis of variance (ANOVA) and unpaired Student's t-test were used to compare the study groups. Post hoc Bonferroni test was used for the degree of significance between groups, and repeated measures analysis of covariance (ANCOVA) was used to investigate the effect of age and gender. IMA and MDA levels were significantly higher in the OCD group compared to the control group, and SOD, CAT and GSH-Px levels were lower in the OCD group compared to the control group (p<0.01). IMA levels were significantly higher in the OCD+MDD group compared to the OCD-MDD group, while SOD, CAT and GSH-Px levels were significantly lower in the OCD+MDD group compared to the OCD-MDD group (p<0101). MDA levels were significantly higher in the OCD+MDD group compared to the OCD-MDD group (p=0.009). When the entire OCD patient group was examined, significant, powerful, positive correlations were observed between Y-BOCS and HDRS scores and IMA and MDA, and significant powerful negative correlations between Y-BOCS and HDRS scores and SOD, CAT, and GSH-Px (p<0.001 for all). In OCD+MDD group, oxidative stress markers increased significantly in parallel with the severity of depression, while antioxidant levels decreased (p=0.003 for IMA, p<0.001 for others). We believe that parameters indicating impaired oxidant/antioxidant balance in patients with obsessive-compulsive disorder may help to elucidate the cause of the disease and may be potentially useful biomarkers in the diagnosis and determination of the severity of comorbid MDD.

SSRI use during acute COVID-19 and risk of long COVID among patients with depression

BackgroundLong COVID, also known as post-acute sequelae of COVID-19 (PASC), is a poorly understood condition with symptoms across a range of biological domains that often have debilitating consequences. Some have recently suggested that lingering SARS-CoV-2 virus particles in the gut may impede serotonin production and that low serotonin may drive many Long COVID symptoms across a range of biological systems. Therefore, selective serotonin reuptake inhibitors (SSRIs), which increase synaptic serotonin availability, may be used to prevent or treat Long COVID. SSRIs are commonly prescribed for depression, therefore restricting a study sample to only include patients with depression can reduce the concern of confounding by indication.MethodsIn an observational sample of electronic health records from patients in the National COVID Cohort Collaborative (N3C) with a COVID-19 diagnosis between September 1, 2021, and December 1, 2022, and a comorbid depressive disorder, the leading indication for SSRI use, we evaluated the relationship between SSRI use during acute COVID-19 and subsequent 12-month risk of Long COVID (defined by ICD-10 code U09.9). We defined SSRI use as a prescription for SSRI medication beginning at least 30 days before acute COVID-19 and not ending before SARS-CoV-2 infection. To minimize bias, we estimated relationships using nonparametric targeted maximum likelihood estimation to aggressively adjust for high-dimensional covariates.ResultsWe analyzed a sample (n = 302,626) of patients with a diagnosis of a depressive condition before COVID-19 diagnosis, where 100,803 (33%) were using an SSRI. We found that SSRI users had a significantly lower risk of Long COVID compared to nonusers (adjusted causal relative risk 0.92, 95% CI (0.86, 0.99)) and we found a similar relationship comparing new SSRI users (first SSRI prescription 1 to 4 months before acute COVID-19 with no prior history of SSRI use) to nonusers (adjusted causal relative risk 0.89, 95% CI (0.80, 0.98)).ConclusionsThese findings suggest that SSRI use during acute COVID-19 may be protective against Long COVID, supporting the hypothesis that serotonin may be a key mechanistic biomarker of Long COVID.

Depression with comorbid juvenile-onset fibromyalgia syndrome novel treatment plan using interpersonal psychotherapy: A case report.

Fibromyalgia syndrome (FMS) affects 2% to 4% of people, with increasing prevalence in Saudi Arabia reaching 13.4%. FMS can occur in adolescents, known as juvenile-onset fibromyalgia (JFM) with comorbidities including depression, anxiety, and psychological stress. Our patient presented to the child and adolescent psychiatry clinic at King Saud University Hospital Medical City. A year before coming to our clinic, at the age of 15 she was initially diagnosed with JFM followed by a comorbid persistent depressive disorder. As a novel treatment method, a combination treatment approach was used, including a pharmacological intervention with Duloxetine, and a non-pharmacological intervention with interpersonal psychotherapy for adolescents. She completed 16 weeks of therapy while monitoring for duloxetine response and side effects. Depressive symptoms were in remission by treatment's end and continued to be in her first month posttreatment follow-up, and the FMS symptoms were also controlled. Our present case highlights a combined approach to treat depression and JFM in adolescents as a novel intervention method thus we strongly recommend utilizing it for similar cases.

Enhancing quality of life in epilepsy with a digital intervention (emyna): Results of the ELAINE randomized controlled trial.

Despite the availability of pharmacological treatment for seizures, people with epilepsy (PwE) commonly experience impairments in quality of life (QoL). Given the limited access to psychosocial treatments for PwE, digital interventions could bridge treatment gaps and help improve QoL. The objective of this study was to examine the effectiveness of emyna, a fully automated digital intervention based on cognitive behavioral therapy (CBT) techniques, in improving health-related QoL among PwE who reported impairments in QoL. A previous trial showed that emyna was effective in improving depressive symptoms among PwE with a comorbid depressive disorder, but its effects on QoL among PwE without comorbid depression remain unknown. A pragmatic randomized controlled trial was conducted with N = 438 PwE (mean age = 37.5, 70.3% women, physician-verified diagnoses) who were assigned to the intervention group (n = 216), which used emyna alongside treatment as usual (TAU), or the control group (n = 222), which received TAU only. QoL and secondary outcomes such as general self-efficacy, medication adherence, general distress, and epilepsy-related work and social adjustment were assessed at baseline, 3 months, and 6 months. The primary outcome was QoL assessed with the Quality of Life in Epilepsy [QOLIE-31] total score at 3 months post-randomization. Findings from the intent-to-treat analyses showed that after 3 months, participants in the intervention group experienced significant and clinically relevant improvements in health-related QoL compared to the control group (baseline-adjusted group difference = 4.5; 95% CI = [2.0, 6.9], p < 0.001; Cohen's d = 0.32). Effects on secondary outcomes did not reach statistical significance. This study extends previous research by demonstrating that emyna facilitates improvements in QoL in a diverse group of PwE treated in routine care settings. This CBT-based digital intervention therefore presents a convenient and cost-effective addition to healthcare providers' treatment repertoire. In our study, we tested a digital program called emyna, which conveys cognitive behavioral therapy (CBT) techniques to help improve the quality of life for people living with epilepsy. We found that those who used emyna alongside their usual treatments felt better about their quality of life compared to those who did not use the program. Emyna offers a new, convenient way for people with epilepsy to manage their condition, which can be used alongside currently available treatments.

Dihydroergotamine and Bromocriptine: Potential Drugs for the Treatment of Major Depressive Disorder and Alzheimer's Disease Comorbidity.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease that is characterized by memory loss and cognitive impairment. Evidence shows that depression is a common co-occurrence in AD patients, and major depressive disorder (MDD) is considered a risk factor for AD. The crosstalk between the biological procedures related to the two disorders makes it very difficult to treat the comorbid conditions caused by them. Considering the common pathophysiological mechanisms underlying AD and MDD, antidepressant drugs may have beneficial therapeutic effects against their concurrence. In this study, we aimed to explore the potential drug candidates for the prevention and treatment of the comorbidity of AD and MDD. First, we screened the potential drugs for treating MDD by evaluating the distances of drug targets to MDD-related genes on the human protein-protein interaction network (PPIN) via a network-based algorithm. Then, the drugs were further screened to identify those that may be effective for AD treatment by analyzing their affinities with tau protein and Aβ42 peptide via molecular docking. Furthermore, the most stable binding modes were identified via molecular dynamics simulations, and the regulatory effects of drug candidates on genes involved in the pathogenesis of AD and MDD were analyzed. A total of 506 MDD-related genes were retrieved, and 831 drug candidates for MDD treatment were screened via the network-based approach. The results from molecular docking and molecular dynamics simulations indicated dihydroergotamine had the lowest binding affinity with tau protein and bromocriptine could form the most stable binding mode with Aβ42 peptide. Further analyses found that both dihydroergotamine and bromocriptine could regulate the expression of genes involved in the pathogenesis of AD and/or MDD in the brain. The exact mechanisms of the two drugs in treating AD and MDD, as well as their comorbidity, are still unclear, and further exploration is needed to evaluate their roles and mechanisms, both in vitro and in vivo. This study revealed that dihydroergotamine and bromocriptine may be the potential drug candidates for the treatment of the comorbidity of AD and MDD, and the therapeutic effects may be achieved by inhibiting the accumulation and aggregation of Aβ42 and tau protein and regulating the expression of disease-related genes in the brain.

Cellular nature of major depressive disorder and alcohol use disorder comorbidity: An overview

Cellular nature of major depressive disorder and alcohol use disorder comorbidity: An overview

Evaluation of serum zonulin and occludin levels in obsessive-compulsive disorder and the effect of major depressive disorder comorbidity.

The aim of this study is to determine whether the levels of zonulin and occludin, tight junctions (TJ) proteins in the intestinal epithelium, will differ between obsessive compulsive disorder (OCD) patients and healthy controls. We also intended to investigate whether these would vary in OCD patients with and without major depressive disorder (MDD) comorbidity and in comparison with healthy controls. Sixty patients diagnosed with OCD and 30 healthy controls were included in the study. The cases were administered the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Hamilton Depression Rating Scale (HDRS). The patients were divided into two subgroups based on their HDRS scores and presence of MDD comorbidity. Zonulin and occludin levels were measured using the ELISA method. The research was carried out between April 2021 and October 2021. Zonulin and occludin levels were significantly higher in the OCD patient group than in the control group (p<0.001). The levels of both were also significantly higher in the OCD patients with MDD comorbidity (OCD+MDD) compared to those without MDD (OCD-MDD) (p<0.001). Zonulin and occludin levels also rose significantly as disease severity increased in the OCD patient group (respectively; p<0.001, p=0.001). The levels of both increased in line with the severity of depression based on HDRS scores in the OCD+MDD group (p<0.001). A positive correlation was determined between the duration of OCD and zonulin and occludin levels. Evaluation of the entire OCD group revealed a moderate positive correlation between Y-BOCS and HDRS scores and zonulin and occludin. Zonulin and occludin levels in this research were significantly higher in the patients with OCD than in the healthy controls. That elevation was positively correlated with disease duration and severity, and the increase was significantly more pronounced in OCD with MDD comorbidity. These findings point to a possible disorder in the intestinal barrier and blood-brain barrier in OCD patients.

Molecular mechanisms of Schisandra chinensis in treating depression-neuropathic pain comorbidity by network pharmacology and molecular docking analysis

This study utilized network pharmacology and docking analyses to explore a groundbreaking therapeutic approach for managing the neuropathic pain and depressive disorder (NP/DD) comorbidity. Schisandra chinensis (SC), a common Chinese medicine, has demonstrated numerous beneficial effects in treating neuropsychological disorders. The main objective of this study was to identify potential bioactive components of SC and investigate their interactions with relevant target genes associated with NP/DD. To gain insights into the underlying molecular mechanisms, GO and KEGG analyses were conducted. Furthermore, molecular docking analysis was employed to validate the therapeutic relevance of SC’s active ingredients. Seven bioactive components of SC, namely Longikaurin A, Deoxyharringtonine, Angeloylgomisin O, Schisandrin B, Gomisin A, Gomisin G, and Gomisin R, exhibited effectiveness in the treatment of NP/DD. From this list, the first five components were selected for further analysis. The analyses revealed a complex network of interactions between the targets of SC and NP/DD, providing valuable information about the molecular mechanisms involved in the treatment of NP/DD with SC. SC components demonstrated the ability to regulate pathways involving tumor necrosis factor (TNF), vascular endothelial growth factor (VEGF), and other growth hormones (GH). Overall, this study contributes to our understanding of the molecular mechanisms underlying the effects of SC in treating NP/DD. Further investigation is necessary to explore the therapeutic potential of SC as a viable strategy for NP/DD comorbidity. These findings lay a solid foundation for future research endeavors in this field, holding potential implications for the development of novel therapeutic interventions targeting NP/DD.

Comorbidity of depression and posttraumatic stress disorder: Outcomes from a randomized controlled trial of surf and hike therapies among service members.

Major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are commonly comorbid mental health disorders. Exercise performed in the natural environment has shown promise in relieving symptoms of each disorder separately; however, the effectiveness has seldom been studied in comorbid populations. Data were derived from a randomized controlled trial of surf and hike therapy for active duty service members with MDD (N = 95). In this study, participants were grouped by comorbidity status (MDD, n = 37; MDD-PTSD, n = 58). Clinician-administered and self-reported measures were completed at preprogram, postprogram, and 3-month follow-up; a brief depression/anxiety measure was completed before and after each session. Multilevel modeling results showed clinically significant decreases in depression severity across participants from pre- to postprogram (p < .001) and within exercise sessions (p < .001), with no further change through follow-up. No significant differences emerged in depression severity change over time by comorbidity status, intervention condition, or their three-way interaction. Those with PTSD showed reductions in posttraumatic stress symptoms from pre- to postprogram (p < .001), which did not differ by intervention condition; gains were maintained at follow-up. Remission rates from MDD and PTSD diagnoses (if applicable) were significant from pre- to postprogram for both MDD-only and MDD-PTSD groups (p < .001). These improvements were maintained at 3 months. Both surf and hike therapies can improve MDD and PTSD symptoms, regardless of comorbidity status, suggesting utility of these interventions among service members with one or both disorders.

Efficacy of Olokizumab against Comorbid Depressive Disorder in Patients with Rheumatoid Arthritis: Preliminary Results of the Study.

Interleukin (IL) 6 plays an important role in the pathogenesis of depression comorbid with rheumatoid arthritis (RA), and IL-6 inhibitors used to treat patients with RA may have an antidepressant effect. The objective of the study was to evaluate the effectiveness of Russian iIL-6 olokizumab (OKZ) in reducing symptoms of depression in patients with moderate/high RA activity. To date, 49 RA patients have been included, of which 43 (87.7%) are women, with an average age of 47.8 ± 12.8 years; with a predominant high activity of RA according to DAS28 (CRP) indices (89.8%), SDAI (79.6%) and CDAI (75.5%) and inefficacy of stable 12-week therapy with сDMARDs. In all patients, a psychiatrist, in accordance with ICD-10, diagnosed depression (chronic or recurrent) of varying severity during a semi-structured interview. At week 0, all patients were randomized by the method of sequential numbers in a ratio of 1 : 1 : 1 to one of the three study groups: group 1-cDMARDs + OKZ 64mg subcutaneously once every 4 weeks (n = 18); group 2-cDMARDs + OKZ 64mg subcutaneously once every 4 weeks + psychopharmacotherapy (PPT) (n = 26); group3-cDMARDs + PPT (n = 5). The duration of the study is 24weeks. Thedynamics of depression severity was assessed on the PHQ-9, MADRS scales; anxiety, on HAM-A; experimental psychological projective techniques were also used. After 12 and 24 weeks of therapy, there was a significant decrease in the severity ofdepression and anxiety in all groups of patients. However, the difference between the final and initial values of all scales was statistically significantly greater (p <0.05) in the groups of patients receiving PPT: cDMARDs + OKZ + PPT (ΔPHQ-9 24-0 = -6.75 ± 3.91; ΔMADRS 24-0 = -22.5 ± 4.83; ΔHAM-A 24-0 = -14.6 ± 5.37) and cDMARDs + PPT (ΔPHQ-9 24-0 = -15.5 ± 3.53; ΔMADRS 24-0 = -25.0 ± 1.41; ΔHAM-A 24-0 = -18.5 ± 3.53), compared with the cDMARDs + OKZ group (ΔPHQ-9 24-0 = -4.00 ± 3.89; ΔMADRS 24-0 = -5.75 ± 8.29; ΔHAM-A 24-0 = -8.50 ± 8.21). According to a semi-structured interview with a psychiatrist and design experimental psychological techniques, the proportion of patients without depression after 24weeks of therapy was significantly higher in the groups of patients receiving PPT: 90% inthe group of cDMARDs + OKZ + PPT and 100%-cDMARDs + PPT, as opposed to 25% in the group of cDMARDs + OKZ. OKZ therapy contributed to the normalization of night sleep but did not lead to a decrease in the frequency and severity of cognitive disorders (CDs). OKZ has an antidepressant effect, leads to a decrease in the frequency of sleep disorders. However, a complete regression of depression symptoms when OKZ is prescribed without PPT is possible only in 25% of RA patients, mainly in the patients with mild depression. A combination of OKZ and PPT is optimal for the complete regression of depression and anxiety and a decrease in the frequency and severity ofCDs.

Potential correlations between asymmetric disruption of functional connectivity and metabolism in major depressive disorder

ObjectivePrevious research has suggested a connection between major depressive disorder (MDD) and certain comorbidities, including gastrointestinal issues, thyroid dysfunctions, and glycolipid metabolism abnormalities. However, the relationships between these factors and asymmetrical alterations in functional connectivity (FC) in adults with MDD remain unclear. MethodWe conducted a study on a cohort of 42 MDD patients and 42 healthy controls (HCs). Participants underwent comprehensive clinical assessments, including evaluations of blood lipids and thyroid hormone levels, as well as resting-state functional magnetic resonance imaging (Rs-fMRI) scans. Data analysis involved correlation analysis to compute the parameter of asymmetry (PAS) for the entire brain's functional connectome. We then examined the interrelationships between abnormal PAS regions in the brain, thyroid hormone levels, and blood lipid levels. ResultsThe third-generation ultra-sensitive thyroid stimulating hormone (TSH3UL) level was found to be significantly lower in MDD patients compared to HCs. The PAS score of the left inferior frontal gyrus (IFG) decreased, while the bilateral posterior cingulate cortex (Bi-PCC) PAS increased in MDD patients relative to HCs. Notably, the PAS score of the left IFG negatively correlated with both TSH and total cholesterol (CHOL) levels. However, these correlations lose significance after the Bonferroni correction. ConclusionMDD patients demonstrated abnormal asymmetry in resting-state FC (Rs-FC) within the fronto-limbic system, which may be associated with CHOL and thyroid hormone levels.

Examining Depression among Breast Cancer Survivors in Nigeria: A Scoping Review

Background: Depression is one of the major mental health problems that hinder recovery of breast cancer patients. Comorbidity of depressive disorder and breast cancer is a complicated medical condition globally. This study examined depression among breast cancer survivors in Nigeria. Methods: This study used a scoping review approach to explore four databases, which include Google Scholar, PubMed, Medline and Scopus. The search produced 50 records using formulated search terms formulated which are relevant to the topics. Of the 50 records selected, 42 articles that did not meet eligible requirements were removed, and 8 records were included. Results: this study revealed that depression is one of the psychological problems that patients with breast cancer experience in Nigeria. In addition, this review revealed that psychological interventions such as cognitive behavioural therapy (CBT) and pilot cognitive restructuring are effective in reducing the depressive symptoms among breast cancer patients in Nigeria. Conclusion: Based on the published peer reviewed articles, depression is major mental health problem among breast cancer patients in Nigeria, and CBT and psychoeducation have been found to be effective treating depression symptoms in Nigeria. However, more studies are needed in the northern parts of the country since most of the review studies were done in the southern parts of the country.

Efficacy of an Internet- and Mobile-Based Intervention for Subclinical Anxiety and Depression (ICare Prevent) with Two Guidance Formats: Results from a Three-Armed Randomized Controlled Trial

Introduction: Limited research exists on intervention efficacy for comorbid subclinical anxiety and depressive disorders, despite their common co-occurrence. Internet- and mobile-based interventions (IMIs) are promising to reach individuals facing subclinical symptoms. Objective: This study aimed to evaluate the efficacy of a transdiagnostic and self-tailored IMI in reducing subclinical anxiety and depressive symptom severity with either individualized (IG-IMI) or automated (AG-IMI) guidance compared to a waitlist control group with care-as-usual access (WLC). Methods: Participants included 566 adults with subclinical anxiety (GAD-7 ≥ 5) and/or depressive (CES-D ≥16) symptoms, who did not meet criteria for a full-syndrome depressive or anxiety disorder. In a three-arm randomized clinical trial, participants were randomized to a cognitive behavioral 7-session IMI plus booster session with IG-IMI (n = 186) or AG-IMI (n = 189) or WLC (n = 191). Primary outcomes included observer-rated anxiety (HAM-A) and depressive (QIDS) symptom severity 8 weeks after randomization assessed by blinded raters via telephone. Follow-up outcomes at 6 and 12 months are reported. Results: Symptom severity was significantly lower with small to medium effects in IG-IMI (anxiety: d = 0.45, depression: d = 0.43) and AG-IMI (anxiety: d = 0.31, depression: d = 0.32) compared to WLC. No significant differences emerged between guidance formats in primary outcomes. There was a significant effect in HAM-A after 6 months favoring AG-IMI. On average, participants completed 85.38% of IG-IMI and 77.38% of AG-IMI. Conclusions: A transdiagnostic, self-tailored IMI can reduce subclinical anxiety and depressive symptom severity, but 12-month long-term effects were absent. Automated guidance holds promise for enhancing the scalability of IMIs in broad prevention initiatives.

Comorbidity of anxiety and depression disorder among clinical referral patients: a longitudinal study based on network analysis

Comorbidity of anxiety and depression disorder among clinical referral patients: a longitudinal study based on network analysis

Epistasis in neurotransmitter receptors linked to posttraumatic stress disorder and major depressive disorder comorbidity in traumatized Chinese.

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) comorbidity occurs through exposure to trauma with genetic susceptibility. Neuropeptide-Y (NPY) and dopamine are neurotransmitters associated with anxiety and stress-related psychiatry through receptors. We attempted to explore the genetic association between two neurotransmitter receptor systems and the PTSD-MDD comorbidity. Four groups were identified using latent profile analysis (LPA) to examine the patterns of PTSD and MDD comorbidity among survivors exposed to earthquake-related trauma: low symptoms, predominantly depression, predominantly PTSD, and PTSD-MDD comorbidity. NPY2R (rs4425326), NPY5R (rs11724320), DRD2 (rs1079597), and DRD3 (rs6280) were genotyped from 1,140 Chinese participants exposed to earthquake-related trauma. Main, gene-environment interaction (G × E), and gene-gene interaction (G × G) effects for low symptoms, predominantly depression, and predominantly PTSD were tested using a multinomial logistic model with PTSD-MDD comorbidity as a reference. The results demonstrated that compared to PTSD-MDD comorbidity, epistasis (G × G) NPY2R-DRD2 (rs4425326 × rs1079597) affects low symptoms (β = -0.66, OR = 0.52 [95% CI: 0.32-0.84], p = 0.008, pperm = 0.008) and predominantly PTSD (β = -0.56, OR = 0.57 [95% CI: 0.34-0.97], p = 0.037, pperm = 0.039), while NPY2R-DRD3 (rs4425326 × rs6280) impacts low symptoms (β = 0.82, OR = 2.27 [95% CI: 1.26-4.10], p = 0.006, pperm = 0.005) and predominantly depression (β = 1.08, R = 2.95 [95% CI: 1.55-5.62], p = 0.001, pperm = 0.001). The two G × G effects are independent. NPY and dopamine receptor genes are related to the genetic etiology of PTSD-MDD comorbidity, whose specific mechanisms can be studied at multiple levels.

ЭПИДЕМИОЛОГИЧЕСКИЕ АСПЕКТЫ НАРУШЕНИЙ МЕНТАЛЬНОГО ЗДОРОВЬЯ – ОТ ПРЕДИКТОРОВ К СЛЕДСТВИЮ

Introduction. Due to the high social significance of mental health disorders, the study of the spread and degree of influence of modifiable predictors of depressive psychoemotional status can contribute to the development of new approaches to active prevention. The purpose of the study. To study the epidemiological characteristics of mental health disorders and identify key predictors among students. Methods. To conduct the study, epidemiological diagnostic methods were used, such as: retrospective epidemiological analysis, descriptive and evaluative methods, as well as statistical methods, methods of epidemiological diagnostics using methods of clinical epidemiology and statistical analysis were used. Results. There was a moderate long-term epidemic trend towards an increase in the incidence of mental disorders (an increase rate of 3.68%) and a high long-term average (164.44+1.72о/оооо). The risk area is determined on the basis of the characteristic pronounced tendency to growth and an increased level of relative epidemiological risk: Minsk region, Minsk, Vitebsk and Mogilev regions (Tpr = 6.56%, 9.99%, 15.21%, and 15.57%, respectively. Consequently, the risks were: in Minsk – 0.77, in Vitebsk and Mogilev regions – 0.78 and 0.86, respectively). The result of our own original research was the identification of a depressive state in 59.25% of cases and generalized anxiety disorder – in 64.1% of cases. An aggravating circumstance is the fact of comorbidity in more than 80% of cases. When studying the epidemiological characteristics of these disorders, significant predictors were identified that increased the chance of developing a state by 2.5-11.5 times. Conclusion. The high levels of prevalence and comorbidity of depressive psychoemotional status and anxiety disorder characterize the general epidemiological situation within the mental health of students as unfavorable and require the development of preventive measures.

Cognitive-behavioral statuses in depression and internet gaming disorder of adolescents: A transdiagnostic approach.

To investigate the comorbidity of adolescent depression and Internet gaming disorder (IGD) and their shared and unique cognitive-behavioral factors (i.e., self-esteem, dysfunctional attitudes, hopelessness, and coping), a large-scale school-based survey was conducted among 3147 Chinese secondary school students in Hong Kong. Probable depression and IGD were screened using the Centre for Epidemiological Studies-Depression Scale and DSM-5 IGD checklist, respectively. Multinomial logistic regression was performed to identify the associations between different condition statuses and cognitive-behavioral factors. Four groups were identified, including comorbidity group (having probable depression and IGD), IGD group (having probable IGD alone), depression group (probable depression alone), and healthy group (neither condition). Comorbidity group showed the worst cognitive-behavioral statuses, followed by depression group and then IGD group. Compared with healthy group, those with lower self-esteem and higher hopelessness and dysfunctional attitudes were more likely to be classified into depression group and comorbidity group, while maladaptive coping was positively associated with all three disorder groups. The results suggest that depression and IGD may share common cognitive-behavioral mechanisms (e.g., maladaptive coping) but also own their uniqueness regarding specific factors (e.g., hopelessness and self-esteem). A transdiagnostic intervention approach targeting the common factors may effectively address the comorbidity.

Unveiling Transitions in Disease States: Study of Depressive and Anxiety Symptom Networks over Time

Background. Major depressive disorder (MDD) and anxiety disorders (AD) have high degrees of comorbidity and show great overlap in symptoms. The analysis of covarying depressive‐ and anxiety symptoms in longitudinal, sparse data panels has received limited attention. Dynamic time warping (DTW) analysis may help to provide new insights into symptom network properties based on diagnostic‐ and disease‐state stability criteria. Materials and Methods. In the Netherlands Study of Depression and Anxiety depressive‐, anxiety‐, and worry symptoms were assessed four or five times over the course of 9 years using self‐report questionnaires. The sample included 1,649 participants at baseline, comprising controls (n = 360), AD patients (n = 158), MDD patients (n = 265), and comorbid AD–MDD patients (n = 866). With DTW, 1,649 distance matrices were calculated, which yielded symptom networks and enabling comparison of network densities among subgroups. Results. The mean age of the sample was 41.5 years (standard deviations, 13.2), of whom 66.4% were female. The largest distance was between worry symptoms and physiological arousal symptoms, implicating the most dissimilar dynamics over time. The network density in the groups, from lowest to highest, followed the order: controls, AD, MDD, and comorbid AD–MDD. The comorbid group showed strongly connected mood and cognitive symptoms, which contrasted with the more strongly connected somatic and arousal symptoms in the AD and MDD groups. Groups that showed more transitions in disease states over follow‐up, regardless of the diagnoses, had the highest network density compared to more stable states of health or disease (beta for quadratic term = −0.095; P &lt; 0.001). Conclusions. Symptom networks over time can be visualized by applying DTW methods on sparse panel data. Network density was highest in patients with comorbid anxiety and depressive disorders and those with more instability in disease states, suggesting that a stronger internal connectivity may facilitate “critical transitions” within the complex systems framework.

LD block disorder-specific pleiotropic roles of novel CRHR1 in type 2 diabetes and depression disorder comorbidity

AbstractMajor depressive disorder (MDD) and type 2 diabetes (T2D) are complex disorders whose comorbidity can be due to hypercortisolism and may be explained by dysfunction of the corticotropin-releasing hormone receptor 1 (CRHR1) and cortisol feedback within the hypothalamic–pituitary–adrenal axis (HPA axis). To investigate the role of the CRHR1 gene in familial T2D, MDD, and MDD-T2D comorbidity, we tested 152 CRHR1 single-nucleotide-polymorphisms (SNPs), via 2-point parametric linkage and linkage disequilibrium (LD; i.e., association) analyses using 4 models, in 212 peninsular families with T2D and MDD. We detected linkage/LD/association to/with MDD and T2D with 122 (116 novel) SNPs. MDD and T2D had 4 and 3 disorder-specific novel risk LD blocks, respectively, whose risk variants reciprocally confirm one another. Comorbidity was conferred by 3 novel independent SNPs. In silico analyses reported novel functional changes, including the binding site of glucocorticoid receptor-alpha [GR-α] on CRHR1 for transcription regulation. This is the first report of CRHR1 pleiotropic linkage/LD/association with peninsular familial MDD and T2D. CRHR1 contribution to MDD is stronger than to T2D and may antecede T2D onset. Our findings suggest a new molecular-based clinical entity of MDD-T2D and should be replicated in other ethnic groups.

Outcomes Among Hospitalized Patients with Acute Chest Syndrome and Concomitant Clinical Depression: A United States Population-Based Cohort Study

Background Acute chest syndrome is a life-threatening complication of sickle cell disease, seen in both children and adults. Hospitalization and immediate treatment are necessary to prevent morbidity and mortality. Clinical depression is quite prevalent in patients with sickle cell disease, and review of literature reveals association of depression with increased annual emergency department visits, hospitalizations, and blood transfusions in patients with sickle cell disease. Whether this leads to worse outcomes is yet to be ascertained. Methods We utilized the 2018-2020 National Inpatient Sample (NIS) Database in conducting a retrospective cohort study. We identified hospitalized patients with acute chest syndrome and concomitant clinical depression using appropriate ICD-10 CM codes. We stratified patients based on whether they had clinical depression during the hospitalization or not. A survey multivariable logistic and linear regression analysis was used to calculate adjusted odds ratios (OR) for the primary and secondary outcomes. A p value of &amp;lt;0.05 was considered statistically significant. The aim of this study is to investigate the outcomes among hospitalized patients with acute chest syndrome and comorbid clinical depression looking primarily at the in-hospital mortality and hospital length of stay (LOS). Results We identified a total of 5271 hospitalized patients with acute chest syndrome, of which 10.72% (565/5271) had comorbid clinical depression. The overall in-hospital mortality among those with acute chest syndrome was 3.70% (195/5271). Among those with clinical depression, the overall in-hospital mortality rate was not significantly higher at 5.31% (30/565) (p=0.385). Utilizing a stepwise survey multivariable logistic regression model that adjusted for patient and hospital level confounders, clinical depression among hospitalized patients with acute chest syndrome did not significantly increase the risk for in-hospital mortality (adjusted OR 1.39, 95% confidence interval [CI], 0.49-3.91; p=0.533) or prolong hospital LOS (median LOS 6 days versus 7 days, p=0.631) Conclusion Acute chest syndrome continues to be an important cause of hospital admissions in patients with sickle cell disease. Our analysis revealed that clinical depression is commonly encountered in this subset of patients. Clinical depression did not have a statistically significant impact on outcomes including increased in-hospital mortality or prolonged hospital LOS. Prospective studies with large sample sizes are needed to better understand these outcomes.
