Depression In Chinese Patients Research Articles

Uncovering the symptom relationshipamongsleep quality, anxiety, and depression in Chinese patients with breast cancer: multidimensional data validation using PSQI versus actigraphy.

The interplay between sleep quality, anxiety, and depression among breast cancer patients remains poorly understood. This study aimed to investigate and compare thesymptoms relationships among these three factors in Chinese breast cancer patients, utilizing two sleep assessments. Our study encompassed 288 participants diagnosed with breast cancer, from whom we collected demographic information through questionnaires. Sleep quality symptoms were assessed using the Pittsburgh Sleep Quality Index (PSQI) and wrist actigraphy, while anxiety and depression symptoms were measured using the Hospital Anxiety and Depression Scale (HADS). Network analyses were conducted using R to calculate the centrality (strength) and further identify central symptoms and bridge symptoms in two networks that differed by sleep assessments. Central symptoms are closely related to other symptoms, whereas bridge symptoms indicate that symptoms may increasespread riskbetween different conditions. In the network using PSQI data, "I have lost interest in my appearance" had the highest strength centrality (rs = 2.417), followed by "sleep duration" (rs = 1.068) and "sleep efficiency" (rs = 0.955). In the network using wrist actigraphy data, "wake after sleep onset" had the highest strength value (rs = 2.437), followed by "sleep efficiency" (rs = 2.397) and "sleep latency" (rs = 1.506). Two bridge symptoms were identified: "I feel cheerful" and "I look forward with enjoyment to things" in both networks. Depressive symptoms played a leading role in the sleep-anxiety-depression network, underscoring the need for targeted intervention tailored to survivors' specific needs. Health workers can give priority to symptom-specific screening and therapies, incorporating psychological support into standard cancer care.

Identification of genetic susceptibility for Chinese migraine with depression using machine learning.

Migraine is a common primary headache that has a significant impact on patients' quality of life. The co-occurrence of migraine and depression is frequent, resulting in more complex symptoms and a poorer prognosis. The evidence suggests that depression and migraine comorbidity share a polygenic genetic background. The aim of this study is to identify related genetic variants that contribute to genetic susceptibility to migraine with and without depression in a Chinese cohort. In this case-control study, 263 individuals with migraines and 223 race-matched controls were included. Eight genetic polymorphism loci selected from the GWAS were genotyped using Sequenom's MALDI-TOF iPLEX platform. In univariate analysis, ANKDD1B rs904743 showed significant differences in genotype and allele distribution between migraineurs and controls. Furthermore, a machine learning approach was used to perform multivariate analysis. The results of the Random Forest algorithm indicated that ANKDD1B rs904743 was a significant risk factor for migraine susceptibility in China. Additionally, subgroup analysis by the Boruta algorithm showed a significant association between this SNP and migraine comorbid depression. Migraineurs with depression have been observed to have worse scores on the Beck Anxiety Inventory (BAI) and the Migraine Disability Assessment Scale (MIDAS). The study indicates that there is an association between ANKDD1B rs904743 and susceptibility to migraine with and without depression in Chinese patients.

Association between handgrip strength and depressive symptoms in patients undergoing hemodialysis: a cross-sectional study from a single Chinese center

BackgroundThe relationship between handgrip strength (HGS) and depression in patients undergoing hemodialysis (HD) was unknown. Therefore, we aimed to clarify this association in a cohort of patients.MethodsHGS was used as a representative indicator of muscle strength and was measured with a handheld dynamometer. Depressive symptoms were assessed with the self-reported Patient Health Questionnaire-9. A multivariable logistic regression model and restricted cubic spline analysis were used to assess the relationship between HGS and depression.ResultsThe prevalence of depression in our study was 34% in 568 Chinese patients undergoing HD. Compared with patients in the lowest tertiles of absolute and weighted HGS, patients in the highest tertiles of HGS had an approximately 59% lower [odds ratio (OR) = 0.41, 95% confidence interval (CI) = 0.24–0.68; OR = 0.41, 95%CI = (0.24–0.69)] prevalence of depressive symptoms after multivariate adjustments. Besides, the risk of depression in hemodialysis patients decreased by 33% (OR = 0.67, 95%CI = 0.53–0.85) and 32% (OR = 0.68, 95%CI = 0.54–0.85) for each standard deviation increase in absolute HGS and weighted HGS, respectively. The prevalence of depressive symptoms decreased with both increasing absolute HGS and weighted HGS after multivariate adjustments (p for trend < 0.05). Furthermore, a linear dose-response relationship was observed between absolute HGS and weighted HGS and the prevalence of depressive symptoms (pnonlinearity>0.05).ConclusionsThis study suggests that lower handgrip strength, a simple and modifiable parameter, is associated with a higher prevalence of depression in Chinese patients undergoing HD. Considering that depression is often unrecognized or underdiagnosed in HD patients, lowered muscle strength should be an important indicator and incentive for medical staff to screen for depression.

Purpose Orientation and Its Protective Effect on Self-Esteem Among Chinese Depressive Patients: A Comparative Study.

Although previous studies have confirmed that purpose in life may negatively predict depressive symptoms, focusing on the intensity of purpose without focusing on content may ignore significant individual differences. This study explores differences in purpose orientations between depressive patients and healthy population to examine the relationship between the purpose content and self-esteem, one of the symptoms of depression. In addition, the moderating role of purpose orientations in the relationship between depression and self-esteem was analyzed to verify the protective effect of purpose orientation on self-esteem. The study utilized the questionnaire approach. The Purpose Orientation Scale (Self and Forced Rating) and the Rosenberg Self-Esteem Scale were administered to the participants. The study recruited 73 depressive patients using convenience sampling. Moreover, using random sampling, 146 participants matched based on depressive patients' demographics were selected as a healthy population in a 1:2 ratio. The results showed that: 1) depressive patients valued all four types of purpose orientations to a lesser extent compared to healthy population, both depressive patients and healthy population valued family well-being and personal growth to a greater extent than personal well-being and social promotion. 2) Depressive patients reported lower self-esteem than healthy people. 3) All four types of Purpose orientations positively correlated with self-esteem in depressive patients, while only personal well-being positively correlated with self-esteem in healthy population. Family well-being and social promotion moderated the predictive effect of depression on self-esteem. The above results imply that prosocial purpose orientations may attenuate the harmful effects of depression on self-esteem. Additionally, intervention focusing on enhancing depressive patients' purpose in life (especially prosocial purpose) could be helpful.

MiR-218-5p and miR-320a-5p as Biomarkers for Brain Disorders: Focus on the Major Depressive Disorder and Parkinson's Disease.

Depression is one of the early and most persistent non-motor symptoms of Parkinson's disease (PD), which remains ignored, resulting in the underdiagnosis of PD. Unfortunately, scarce studies and the non-availability of diagnostic strategies cause countless complications, highlighting the need for appropriate diagnostic biomarkers. Recently, brain-enriched miRNAs regulating vital neurological functions have been proposed as potent biomarkers for therapeutic strategies. Therefore, the present study is aimed to identify the brain-enriched miR-218-5p and miR-320-5p in the serum of the Chinese depressed PD patients (n = 51) than healthy controls (n = 51) to identify their potency as biomarkers. For this purpose, depressive PD patients were recruited based on HAMA and HAMD scores and miR-218-5p and miR-320-5p and IL-6, and S100B levels were analyzed using real-time PCR (qRT-PCR) and ELISA assay, respectively. In silico analysis was performed to identify key biological pathways and hub genes involved in the psychopathology of depression in PD. Here, we found significantly downregulated miR-218-5p and miR-320-5p following higher levels of IL-6 and S100B in depressed PD patients than in control (p < 0.05). The correlation analysis revealed that both miRNAs were negatively correlated with HAMA and HAMD, and IL-6 scores, along with a positive correlation with PD duration and LEDD medication. ROC analysis showed AUC above 75% in both miRNAs in depressed PD patients, and in silico analysis revealed that both miRNA's targets regulate key neurological pathways such as axon guidance, dopaminergic synapse, and circadian rhythm. Additional analysis revealed PIK3R1, ATRX, BM1, PCDHA10, XRCC5, PPP1CB, MLLT3, CBL, PCDHA4, PLCG1, YWHAZ, CDH2, AGO3, PCDHA3, and PCDHA11 as hub-genes in PPI network. In summary, our findings show that miR-218-5p and miR-320-5p can be utilized as future biomarkers for depression in PD patients, which may aid in the early diagnosis and treatment of Parkinson's disease.

Depression in Chinese Patients with Cleft Lip and/or Palate: A Preliminary Study

(1) Objectives: To investigate the difference in prevalence of depression between patients with CL/P (cleft lip and/or palate) and analyze the possible demographic factors that affect the prevalence of depression in Chinese patients with CL/P. (2) Methods: Patients with CL (cleft lip only), CP (cleft palate), and CLP (cleft lip and palate) were included in the study group. Non-CL/P individuals were included in the control group. The Patient Health Questionnaire (PHQ-9) was used to screen the depression of Chinese patients with CL/P. The different proportions of different depression groups between the CL/P group and the control groups were tested by the Fisher-Freeman-Halton test and Bonferroni correction. The scores between the study groups and the control group were analyzed by one-way ANOVA. In the study groups, demographic and clinical data of the patients, including diagnosis (CL, CP, CLP), gender, age, the only child or not, and region were collected to analyze whether they were the possible factors affecting depression through one-way independent-samples t-test. Pearson correlation analysis was used to analyze the correlation between monthly family income and depression. (3) Results: 111 and 80 valid questionnaires were collected from the study and control groups, respectively. The mean PHQ-9 score of the study group (5.459 ± 6.082) was relatively higher than the control group (4.362 ± 3.384), and the difference in proportions of depression groups was statistically significant between the CL/P group and the control group (p = 0.01), especially in the mild depression (p < 0.05) and moderately severe depression groups (p < 0.05). Statistically significant differences in PHQ-9 scores were observed between the individuals of different genders (p = 0.036) and ages (p = 0.007) in patients with CL/P, the individuals who were the only child or not in patients with CL (p = 0.007), and the individuals of different ages in patients with CP (p = 0.016). (4) Conclusions: The prevalence of depression in Chinese patients with CL/P was different compared with those without CL/P, while gender, age, the only child or not, and region played significant roles in affecting depression psychology.

The host genetics affects gut microbiome diversity in Chinese depressed patients.

The gut microbiome and host genetics are both associated with major depressive disorder (MDD); however, the molecular mechanisms among the associations are poorly understood, especially in the Asian, Chinese group. Our study applied linear discriminant analysis (LDA) effect size (LEfSe) and genome-wide association analysis in the cohort with both gut sequencing data and genomics data. We reported the different gut microbiota characteristics between MDD and control groups in the Chinese group and further constructed the association between host genetics and the gut microbiome. Actinobacteria and Pseudomonades were found more in the MDD group. We found significant differences in the ACE and Chao indexes of alpha diversity while no discrepancy in beta diversity. We found three associations between host genetics with microbiome features: beta diversity and rs6108 (p = 8.65 × 10-9), Actinobacteria and rs77379751 (p = 8.56 × 10-9), and PWY-5913 and rs1775633082 (p = 4.54 × 10-8). A species of the Romboutsia genus was co-associated with the species of Ruminococcus gnavus in an internetwork through four genes: METTL8, ITGB2, OTULIN, and PROSER3, with a strict threshold (p < 5 × 10-4). Furthermore, our findings suggested that the gut microbiome diversity might affect microRNA expression in the brain and influenced SERPINA5 and other spatially close genes afterward. These findings suggest new linkages between depression and gut microbiome in Asian, Chinese people, which might be mediated by genes and microRNA regulation in space distance.

Translation, cross-cultural adaptation, and psychometric investigation of Chinese version of the Orbach & Mikulincer Mental Pain Scale in patients with depressive disorder.

This study aimed to translate, cross-culturally adapt, and preliminarily test the psychometric properties of the Chinese version of the Orbach & Mikulincer Mental Pain Scale (OMMP). Psychometric investigation was performed on 240 depressed patients. The reliability of the Chinese version of the OMMP scale was expressed by internal consistency reliability and test-retest reliability (2-week interval), and confirmatory factor analysis (CFA) on the 8-factor, 31-item OMMP was conducted to examine the construct validity. The CFA showed that the modified model with 31 items had good reliability (Cronbach's α range = 0.691-0.871; ICC = 0.818). Criterion-related validity was also supported by significant and positive correlations between the eight factors and worst-ever suicidal ideation as well as depressive symptoms. The results indicated the usefulness of the OMMP-31 for Chinese depressed patients. It is necessary to estimate psychological pain to improve suicide management in the clinical setting.

Prevalence and risk factors of depression in Chinese patients with type 2 diabetes mellitus: a protocol of systematic review and meta-analysis

BackgroundThe prevalence of type 2 diabetes mellitus (T2DM) is growing in China. Depression is a significant complication of T2DM, leading to poor management of T2DM. Thus, early detection and treatment of depression in patients with T2DM are essential and effective. Therefore, we plan to conduct a systematic review and meta-analysis to evaluate the prevalence of depression in Chinese patients with T2DM and explore potential risk factors of depression in T2DM.MethodsWe will search literatures recorded in MEDLINE, EMBASE, the Cochrane Library, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Database (VIP), and WanFang Database from their inception onwards. We will manually search gray literatures, reference lists of identified studies, relevant websites, and consult experts in this field. We will include population-based, cross-sectional surveys that investigated the prevalence of depression in Chinese patients with T2DM or/and the possible risk factors of depression in T2DM. Two reviewers will screen studies, extract data, and evaluate risk of bias independently. Agency for Healthcare Research and Quality methodology checklist will be used to assess the risk of bias. If feasible, we will conduct random effects meta-analysis of observational data to summarize the pooled prevalence, and use odds ratio for categorical data to explore potential risk factors. Prevalence estimates will be stratified according to age, gender, and other factors. Statistical heterogeneity will be estimated using Cochran’s Q and I2 index. We will conduct meta-regression to investigate the potential sources of heterogeneity, sensitivity analyses to assess robustness of the synthesized results, and funnel plots and Egger’s test to assess publication bias.DiscussionThis systematic review and meta-analysis will provide comprehensive evidence of the prevalence and potential risk factors of depression in Chinese patients with T2DM. We expect to provide evidence for healthcare practitioners and policy makers to pay attention to the mental health of patients with T2DM. Our data will highlight the need and importance of early detection and intervention for depression in patients with T2DM.Systematic review registrationPROSPERO CRD42020182979.

Nonpsychotic mental disorders in patients with aseptic necrosis of the femoral head (literature review)

Recently it has been reported of significant progress in the providing of surgical care to patients with aseptic necrosis of the femoral head. Given the unity of mental and somatic factors, as well as data on the interaction of mental factors and other chronic diseases of the hip joint, there is a significant link between non-psychotic mental disorders and aseptic necrosis of the femoral head. The aim of this review was to present current data on psychiatric disorders in patients of this category. Prolonged stress exposure, in particular due to pain, with activation of the sympathoadrenal system on the one hand and maintaining a high level of anxiety due to neurotic mechanisms of psychological protection on the other hand can lead to joint damage due to reduced sympathetic nerve fibers. Available data for incidence of anxiety and depression in Chinese patients show that almost every fifth patient has clinically significant symptoms. The stage of the disease (the need for surgical treatment) and comorbid diseases significantly increase the risk of anxiety and depression. Considerable attention is paid to the patient’s alcohol consumption problems and the relationship between alcohol abuse and the occurrence of aseptic necrosis. The presence of restrictions in movements influent not only to the physical, but also to the mental components of the quality of life. Physical and mental discomfort, pain, low quality of life are factors that reduce the willingness to participate in preventive measures, which ultimately leads to the need for more radical surgical intervention. Evaluation by a mental health professional before hip surgery allows for better results in the delayed recovery period.

A correlation study of intestinal microflora and first-episode depression in Chinese patients and healthy volunteers.

ObjectiveThis research examines the intestinal‐associated flora of patients with depression compared with healthy volunteers to identify the characteristics and differences of flora associated with depression. It provides a theoretical basis for the prevention and treatment of depression through intestinal micro‐ecological regulation.MethodsWe recruited 30 patients with depression to participate in the patient group (PG), and 30 volunteers were recruited for the healthy control group (HG) from the Beijing Hui‐long‐guan Hospital. Thereafter, the 16S rRNA high‐throughput sequencing method, using the Hamilton Depression Scale, was applied to analyze patient and healthy groups.ResultsPG and HG microflora were different regarding phylum, Family, Genus, and Order. The results showed that Barnesiella was the dominant flora in depression patients, while Lachnospiraceae and Alloprevotella were the dominant bacteria in healthy participants. The proportion of Betaproteobateria (Proteobacteria), Alcaligenaceae (proinflammatory), Peptostreptococcaceae, Catenibacterium, Romboutsia, Sutterella, and Burkholderiales in the anxiety‐negative depressed group was significantly higher than in the anxiety‐positive group; and the proportion of Anaerostipes (inflammation) and Faecalibacterium (anti‐inflammatory) bacteria was significantly lower than that of patients with anxiety.ConclusionResults showed there were differences in intestinal micro‐ecology between patients with depression and healthy volunteers. We found that the level of inflammation‐related bacteria in anxiety‐positive patients was lower than that in anxiety‐negative patients. These results enrich the knowledge of relationships between depression and intestinal flora and provide a theoretical basis for probiotics to assist in the treatment of depression.

Plasma levels of interleukin-6 and antidepressant response to Paroxetine in Chinese depressive patients

This study aimed to investigate the correlation between interleukin-6 (IL-6) plasma levels and treatment outcomes of selective serotonin reuptake inhibitors in patients with major depressive disorder (MDD). A total of 104 patients (33 males and 71 females), aged 18 to 72 years, were enrolled. Peripheral blood samples were collected before treatment initiation (baseline) and eight weeks after oral paroxetine treatment. The Hamilton Depression Rating Scale (HAMD)-17 was used to evaluate the efficacy of paroxetine. Baseline plasma IL-6 levels were found to be significantly lower in patients who responded to treatment than in non-responders. A negative correlation was found between the HAMD-17 reduction rate and baseline IL-6 levels. Furthermore, associations were examined between HAMD-17 reduction rate in patients and other factors, such as IL-6 levels, sex, age, and body mass index. Baseline IL-6 was the only factor showing a significant impact on the reduction rate of HAMD-17 at week 8. These results suggest that plasma IL-6 level may be a promising biological marker for predicting the likely treatment response to paroxetine in individual patients with MDD.

Feelings in the body: Cultural variations in the somatic concomitants of affective experience.

Affective science research has investigated how the sociocultural context shapes the bodily experience of emotion. Similarly, in the culture and mental health literature, there is a history of research on cultural variations in the presentation of somatic symptoms. A well-known example of the latter is the finding that Chinese depressed patients report more somatic symptoms compared to their "Western" counterparts. The present study represents a first step toward integrating these efforts. We examined reports of somatic and affective changes in 48 Chinese/Chinese American (CH) and 53 European American (EA) women responding to a sad film. Although CH and EA women reported experiencing similar levels of sadness, CH women experienced higher levels of somatic sensations (e.g., changes in heartbeat) relative to EA women. CH participants' reports of somatic changes were negatively associated with orientation to American culture. These findings suggest that cultural context shapes the subjective experience of somatic changes associated with sadness. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

A cultural validation of the Chinese version of multidimensional depression assessment scale (MDAS) in clinically depressed patients in Inner Mongolia

Depression symptoms and assessment in China are influenced by unique cultural values of collectivism and by social-political factors specific to China. This study validated the Chinese version of the 52-item Multidimensional Depression Assessment Scale (MDAS) with clinically depressed patients in Inner Mongolia. The study sought to examine the psychometric properties of the MDAS and understand the construct of depression in a specific collectivistic cultural context using a scale with comprehensive dimensions of depressive symptoms in the emotional, cognitive, somatic and interpersonal domains. A total of 171 clinically depressed participants in Inner Mongolia completed the Chinese versions of the MDAS and the Beck Depressive Inventory (BDI). The reliability and validity of the MDAS were tested, and an exploratory factor analysis (EFA) was conducted on the MDAS to examine the underlying structure of the measure. The MDAS and BDI were compared in terms of sensitivity and reactivity on the basis of the cut-off value of BDI. The Chinese-MDAS was found to have good psychometric properties, including high Cronbach’s alphas for the total scale and for each subscale (0.90–0.97), indicating good reliability, as well as a high and significant correlation with the BDI (r = 0.72; p < .001), suggesting good validity. The factor analysis indicated the emergence of a salient factor of interpersonal symptoms in Chinese depressed patients, suggesting the importance of interpersonal symptoms in Chinese depressed individuals. A cut-off value of 118.5 with high sensitivity and specificity was found on the MDAS based on the cut-off value of the BDI. The Chinese-MDAS demonstrated good psychometric properties among depressed individuals in Inner Mongolia. This study paves the way for the measure’s further development and cultural adaptation in a Chinese depressed population.

Prevalence of and risk factors for anxiety and depression in Chinese patients with unruptured intracranial aneurysms treated by endovascular intervention

BackgroundStudies on anxiety and depression in unruptured intracranial aneurysm (UIA) patients after treatment via endovascular intervention are rare and controversial. We aimed to explore the prevalence of anxiety and depression among Chinese patients with UIAs treated by endovascular intervention and to identify which factors contribute to the development of these symptoms.MethodsWe performed a cross-sectional study on anxiety and depression in patients who underwent endovascular treatment for UIAs using the Hospital Anxiety and Depression Scale (HADS). The demographic, clinical and radiological data for all patients were retrospectively collected from the aneurysm database and medical records. Moreover, we utilized data from a large sample of 200 UIA patients and multivariate logistic regression analysis to investigate the risk factors for anxiety and depression in these patients. Candidate variables with P values less than 0.20 in univariate analysis were included in the multivariate logistic regression analysis.ResultsTwo hundred patients returned completed questionnaires in this study. Of these 200 patients, 34 (17.0%) suffered from anxiety and 31 (15.5%) suffered from depression 30.67 ± 8.6 months after being discharged. The multivariate analysis results indicated that shorter sleep times were statistically significantly associated with depression (OR = 1.62, 95% CI: 1.14 ~ 2.29, P = 0.007, Adjusted P = 0.02). .ConclusionThe prevalences of anxiety and depression in UIA patients treated by endovascular intervention were 17.0 and 15.5%, respectively. Shorter sleep times were significantly associated with depression. Our findings provide evidence for the clinical and psychological management of these patients.

Biases of Happy Faces in Face Classification Processing of Depression in Chinese Patients.

We explored the face classification processing mechanism in depressed patients, especially the biases of happy faces in face classification processing of depression. Thirty patients with the first episode of depression at the First Affiliated Hospital of Harbin Medical University were selected as the depression group, while healthy people matched for age, gender, and educational level were assigned to the control group. The Hamilton Depression Scale and Hamilton Anxiety Scale were used to select the subjects; then, we used the forced face classification paradigm to collect behavioral (response time and accuracy) and event-related potential (ERP) data of the subjects. The differences between the groups were estimated using a repeated measurement analysis of variance. The total response time of classified faces in the depression group was longer than that in the control group, the correct rate was lower, and the difference was statistically significant (P < 0.05). N170 component analysis demonstrated that the latency of the depression group was prolonged, and the difference was statistically significant (P < 0.05). When classifying happy faces, the depressed patients demonstrated a decrease in N170 amplitude and a prolongation of latency in some brain regions compared with the healthy individuals. The cognitive bias in depression may be due to prolonged processing of positive facial information and difficulty in producing positive emotional responses.

Decreased Serum Netrin-1 as a Predictor for Post-Stroke Depression in Chinese Patients with Acute Ischemic Stroke

Background and AimsExperimental studies demonstrated that netrin-1 (NT-1) is an important factor influencing the recovery after ischemic stroke. However, whether NT-1 levels were associated with the post-stroke depression (PSD) remains unclear. We aimed to evaluate the relationship between NT-1 levels and PSD at 3 months in patients with ischemic stroke. MethodsFrom January 2018 to December 2019, consecutive Chinese patients with first-ever ischemic stroke were prospectively recruited. Serum NT-1 levels were measured at admission. Patients with a 17-item Hamilton Depression Scale score of ≥7 were given the Structured Clinical Interview of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, for diagnosis of PSD. ResultsA total of 238 patients (mean age, 62.5 years; 45.4% female) were enrolled. The median NT-1 concentrations were 467.8 pg/mL (interquartile range, 351.8–581.0 pg/mL). During the 3-month follow-up period, 64 patients (26.9%) experienced PSD. Serum NT-1 levels were significantly lower in PSD patients than in patients without PSD (median, 380.3 pg/mL versus 478.5 pg/mL; P = 0.001). After adjusting for demographic characteristic, National Institutes of Health stroke score, and other potential confounders by multiple logistic regression analysis, patients with NT-1 levels in the first quartile were more likely to have 3-month PSD (as compared with the fourth quartile, odds ratio 3.83, 95% confidence intervals, 1.53–9.63, P = 0.004). Similar significant findings were observed when the NT-1 levels were added as a continuous variable. ConclusionsOur data demonstrated that decreased serum NT-1 levels, in a Chinese population, were significantly associated with PSD at 3 months.

Association between cognition and suicidal ideation in patients with major depressive disorder: A longitudinal study

BackgroundSuicidal ideation (SI) is common in patients with major depressive disorder (MDD) and often related to cognitive deficits. Limited longitudinal study has shown that cognitive improvement is associated with reduced SI. However, the comparatively study in Chinese depressed patients is still absent. The objective of this study was to explore the specific cognitive deficits in Chinese MDD with SI and investigate the relationship between changes in cognition and change in SI across antidepressant treatment. MethodsThree hundred and five patients with MDD received four weeks of antidepressant treatment. The 17-item Hamilton Depression Rating Scale (HAMD-17) and four domains of the MATRICS Consensus Cognitive Battery (MCCB), including speed of processing, working memory, visual learning and verbal learning were measured at baseline and four-week follow-up. ResultsOne hundred and thirty patients (42.6%) expressed suicidal ideation. Suicidal patients performed worse on verbal learning than non-suicidal patients. Change in speed of processing domain was negatively associated with change in suicidal scores over time. Logistic regression analysis showed that reduction of SI was associated with improvement of speed of processing. LimitationThe major limitation was that there was no healthy control group in the current study, which might limit the interpretation of cognitive deficits in depressed patients with SI. ConclusionsOur findings suggest that suicidal patients performed worse on verbal learning which can potentially serve as a cognitive biomarker of suicide risk in MDD. Moreover, reduced suicidal ideation was associated with improved speed of processing.

Prevalence and associated factors of depressive symptoms among chronic kidney disease patients in China: Results from the Chinese Cohort Study of Chronic Kidney Disease (C-STRIDE)

ObjectiveDepression is the most common mental disorder in patients with chronic kidney disease (CKD), and previous studies have found that: (a) depression can accelerate the progression of CKD; and (b) depression is an independent risk factor for hospitalization and death among patients with CKD. Therefore, the objective of the current study was to investigate the prevalence of depression in Chinese patients with CKD, and to identify variables associated with depression. MethodsThe study analyzed baseline data from a multicenter prospective cohort study of Chinese patients with chronic kidney disease (the C-STRIDE study). In all, 2995 participants in CKD stages 1 to 4 who completed a survey of depressive symptoms were included in the analyses. Depressive symptoms were assessed by the Zung Self-Rating Depression Scale (ZSDS). A ZSDS ≥50 was used as the cut-off score for the presence of depressive symptoms. Multivariable logistic regression was used to identify variables associated with depression. ResultsThe mean estimated glomerular filtration rate (eGFR) in the study sample was 51.59±29.49 ml/min/1.73 m2. The prevalence of depressive symptoms was 37.8% and increased significantly with CKD stage. Being female, a higher level of education, a low income, a larger economic impact of disease cost, comorbid cardiovascular disease, anemia, and impaired physical ability were independently associated with depressive symptoms. ConclusionOur study revealed that depressive symptoms were common among patients with CKD in China. Sociodemographic variables and the clinical characteristics of disease severity were strongly associated with depressive symptoms.
