文摘BACKGROUND Addison’s disease(AD)is a rare but potentially fatal disease in Western countries,which can easily be misdiagnosed at an early stage.Severe adrenal tuberculosis(TB)may lead to depression in patients.CASE SUMMARY We report a case of primary adrenal insufficiency secondary to adrenal TB with TB in the lungs and skin in a 48-year-old woman.The patient was misdiagnosed with depression because of her depressed mood.She had hyperpigmentation of the skin,nails,mouth,and lips.The final diagnosis was adrenal TB that resulted in the insufficient secretion of adrenocortical hormone.Adrenocortical hormone test,skin biopsy,T cell spot test of TB,and adrenal computed tomography scan were used to confirm the diagnosis.The patient’s condition improved after hormone replacement therapy and TB treatment.CONCLUSION Given the current status of TB in high-burden countries,outpatient doctors should be aware of and pay attention to TB and understand the early symptoms of AD.
文摘BACKGROUND The detection rate of depression among university students has been increasing in recent years,becoming one of the main psychological diseases that endangers their physical and mental health.According to statistics,self-harm and suicide,for which there is no effective intervention,are the second leading causes of death.AIM To explore the relationship between different elements and levels of physical activity and college students’depression-symptom-specific working memory indicators.METHODS Of 143 college students were analyzed using the Beck Depression Self-Rating Scale,the Physical Activity Rating Scale,and the Working Memory Task.RESULTS There was a significant difference between college students with depressive symptoms and healthy college students in completing verbal and spatial working memory(SWM)tasks correctly(all P<0.01).Physical Activity Scale-3 scores were significantly and positively correlated with the correct rate of the verbal working memory task(r=0.166)and the correct rate of the SWM task(r=0.210)(all P<0.05).There were significant differences in the correct rates of verbal and SWM tasks according to different exercise intensities(all P<0.05)and different exercise durations(all P<0.05),and no significant differences in the correct rates of verbal and SWM tasks by exercise frequency(all P>0.05).CONCLUSION An increase in physical exercise among college students,particularly medium-and high-intensity exercise and exercise of 30 min or more,can improve the correct rate of completing working memory tasks.

文摘BACKGROUND The literature has discussed the relationship between environmental factors and depressive disorders;however,the results are inconsistent in different studies and regions,as are the interaction effects between environmental factors.We hypo-thesized that meteorological factors and ambient air pollution individually affect and interact to affect depressive disorder morbidity.AIM To investigate the effects of meteorological factors and air pollution on depressive disorders,including their lagged effects and interactions.METHODS The samples were obtained from a class 3 hospital in Harbin,China.Daily hos-pital admission data for depressive disorders from January 1,2015 to December 31,2022 were obtained.Meteorological and air pollution data were also collected during the same period.Generalized additive models with quasi-Poisson regre-ssion were used for time-series modeling to measure the non-linear and delayed effects of environmental factors.We further incorporated each pair of environ-mental factors into a bivariate response surface model to examine the interaction effects on hospital admissions for depressive disorders.RESULTS Data for 2922 d were included in the study,with no missing values.The total number of depressive admissions was 83905.Medium to high correlations existed between environmental factors.Air temperature(AT)and wind speed(WS)significantly affected the number of admissions for depression.An extremely low temperature(-29.0℃)at lag 0 caused a 53%[relative risk(RR)=1.53,95%confidence interval(CI):1.23-1.89]increase in daily hospital admissions relative to the median temperature.Extremely low WSs(0.4 m/s)at lag 7 increased the number of admissions by 58%(RR=1.58,95%CI:1.07-2.31).In contrast,atmospheric pressure and relative humidity had smaller effects.Among the six air pollutants considered in the time-series model,nitrogen dioxide(NO_(2))was the only pollutant that showed significant effects over non-cumulative,cumulative,immediate,and lagged conditions.The cumulative effect of NO_(2) at lag 7 was 0.47%(RR=1.0047,95%CI:1.0024-1.0071).Interaction effects were found between AT and the five air pollutants,atmospheric temperature and the four air pollutants,WS and sulfur dioxide.CONCLUSION Meteorological factors and the air pollutant NO_(2) affect daily hospital admissions for depressive disorders,and interactions exist between meteorological factors and ambient air pollution.

文摘We previously showed that death-associated protein kinase 1(DAPK1)expression is increased in hippocampal tissue in a mouse model of major depressive disorde and is related to cognitive dysfunction in Alzheimer's disease.In addition,depression is a risk factor for developing Alzheimer's disease,as well as an early clinical manifestation of Alzheimer's disease.Meanwhile,cognitive dysfunction is a distinctive feature of major depressive disorder.Therefore,DAPK1 may be related to cognitive dysfunction in major depressive disorder.In this study,we established a mouse model of major depressive disorder by housing mice individually and exposing them to chronic,mild,unpredictable stressors.We found that DAPK1 and tau protein levels were increased in the hippocampal CA3 area,and tau was hyperphosphorylated at Thr231,Ser262,and Ser396 in these mice.Furthermore,DAPK1 shifted from axonal expression to overexpression on the cell membrane.Exercise and treatment with the antidepressant drug citalopram decreased DAPK1 expression and tau protein phosphorylation in hippocampal tissue and improved both depressive symptoms and cognitive dysfunction.These results indicate that DAPK1 may be a potential reason and therapeutic target of cognitive dysfunction in major depressive disorder.

文摘Background:Adolescents are highly vulnerable to depressive symptoms worldwide partially because of limited social supports.However,it still remains largely unknown regarding the associations between social support(s)and depressive symptoms among adolescents living in low-and middle-income countries(LMICs).The aim of this study aimed to explore the associations between different types of social support and depressive symptoms in adolescents from LMICs.Methods:Data were retrieved from the Global School-based Health Survey(GSHS)in which 92,551 adolescents(50.6%females)were included with mean of 15.6 years.Depressive symptoms in the past one month as the dependent variable were measured in combination with social support(was measured by“During the past 30 days,how often were most of the students in your school kind and helpful?”).Multivariable logistic regression and meta-analysis of country-wise estimates were performed to investigate the associations between social support and depressive symptoms,and the heterogeneity of the associations across the countries,respectively.Results:The prevalence of depressive symptoms was 30.9%of adolescents from LMICs.Peer support and parental connectedness were two major factors that were significantly associated with depression symptoms in adolescents.However,the associations of peer support and parental connectedness with depressive symptoms were significant in males and females,respectively.The country-wise analysis indicated that varied inconsistency(small to large)across the associations of peer support and parental connectedness with depressive symptoms in adolescents.Conclusion:Results in this study provides multi-national evidence of the protective roles of social support against depressive symptoms among adolescents.However,the association between social support and depression symptoms may be moderated by sex and types of social support.Although we found that social sup-port may be an important protective factor against depressive symptoms in adolescents from LMICs,specifically designed interventions should be implemented based on sex difference and country difference.

文摘BACKGROUND Major depressive disorder(MDD)is the most frequent reason of disabled people in the world,as reported by the World Health Organization.However,the diagnosis of MDD is mainly based on clinical symptoms.CASE SUMMARY The clinical,genetic,and molecular characteristics of two Chinese families with MDD are described in this study.There were variable ages of onset and severity in depression among the families.Both Chinese families had a very low prevalence of MDD.The mitochondrial genomes of these pedigrees were sequenced and indicated a homoplasmic T3394C(Y30H)mutation,with the polymorphism located at a highly conserved tyrosine at position 30 of ND1.The analysis also revealed unique sets of mitochondrial DNA(mtDNA)polymorphisms originating from haplogroups M9a3 and M9a.CONCLUSION This finding of the T3394C mutation in two unrelated depressed patients provides strong evidence that this mutation may have a part in the etiology of MDD.However,In these two Chinese families having the T3394C mutation,no functional mt DNA mutation was observed.Therefore,T3394C mutations are related with MDD,and the phenotypic manifestation of these mutations may be affected by changes in nuclear genes or environmental factors.

文摘BACKGROUND Major depressive disorder(MDD)is a common and serious mental illness.Many novel genes in MDD have been characterized by high-throughput methods such as microarrays or sequencing.Recently,noncoding RNAs(ncRNAs)were suggested to be involved in the complicated environmental-genetic regulatory network of MDD occurrence;however,the interplay among RNA species,including protein-coding RNAs and ncRNAs,in MDD remains unclear.AIM To investigate the RNA expression datasets downloaded from a public database and construct a network based on differentially expressed long noncoding RNA(lncRNAs),microRNAs(miRNAs),and mRNAs between MDD and controls.METHODS Gene expression data were searched in NCBI Gene Expression Omnibus using the search term“major depressive disorder.”Six array datasets from humans were related to the search term:GSE19738,GSE32280,GSE38206,GSE52790,GSE76826,and GSE81152.These datasets were processed for initial assessment and subjected to quality control and differential expression analysis.Differentially expressed lncRNAs,miRNAs,and mRNAs were determined,Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed,and protein-protein interaction network was generated.The results were analyzed for their association with MDD.RESULTS After analysis,3 miRNAs,12 lncRNAs,and 33 mRNAs were identified in the competing endogenous RNA network.Two of these miRNAs were earlier shown to be involved in psychiatric disorders,and differentially expressed mRNAs were found to be highly enriched in pathways related to neurogenesis and neuroplasticity as per Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses.The expression of hub gene fatty acid 2-hydroxylase was enriched,and the encoded protein was found to be involved in myelin formation,indicating that neurological development and signal transduction are involved in MDD pathogenesis.CONCLUSION The present study presents candidate nc RNAs involved in the neurogenesis and neuroplasticity pathways related to MDD.
文摘Serotonin deficiency in major depressive disorder(MDD)has formed the basis of antidepressant drug development and was originally attributed to induction of the major tryptophan(Trp)-degrading enzyme,liver Trp 2,3-dioxygenase(TDO),by cortisol,leading to decreased Trp availability to the brain for serotonin synthesis.Subsequently,the serotonin deficiency was proposed to involve induction of the extrahepatic Trp-degrading enzyme indoleamine 2,3-dioxygenase(IDO)by proinflammatory cytokines,with inflammation being the underlying cause.Recent evidence,however,challenges this latter concept,as not all MDD patients are immune-activated and,when present,inflammation is mild and/or transient.A wide range of antidepressant drugs inhibit the activity of liver TDO and bind specifically to the enzyme,but not to IDO.IDO induction is not a major event in MDD,but,when it occurs,its metabolic consequences may be masked and overridden by upregulation of kynurenine monooxygenase(KMO),the gateway to production of modulators of immune and neuronal functions.KMO appears to be activated in MDD by certain proinflammatory cytokines and antidepressants with anti-inflammatory properties may block this activation.We demonstrate the ability of the antidepressant ketamine to dock(bind)to KMO.The pathophysiology of MDD may be underpinned by both the serotonin deficiency and glutamatergic activation mediated respectively by TDO induction and N-methyl-D-aspartate receptor activation.Inhibition of TDO and KMO should be the focus of MDD pharmacotherapy.

文摘BACKGROUND Depression is the most common mental illness in postpartum mothers,and the etiology of postpartum depression remains poorly understood.Over the past several decades,studies have reported that postpartum depression is caused by multiple factors,such as genetic,psychological,pregnancy,and environmental factors,with the family environment being an important environmental factor.The theory of family cohesion and adaptability put forward by Olson is a classic model that describes the level of family function.However,to date,this model has not been examined regarding its applicability to patients with postpartum depression.AIM To investigate the relationship between family cohesion and adaptability and the risk of postpartum depressive symptoms.METHODS We retrospectively analyzed 1446 patients admitted to the postpartum healthcare clinic of the Affiliated Foshan Maternity and Child Healthcare Hospital from April 2021 to December 2021.Patients were grouped according to whether postpartum depression symptoms were reported(symptoms,n=454;no symptoms,n=992).All patients completed the Edinburgh Postpartum Depression Scale and the Chinese version of the Family Cohesion and Adaptability Assessment Scale II.Baseline and clinical data were compared between groups.Univariate regression analysis was used to investigate the association between different types of family cohesion and postpartum depressive symptoms and the association between different family adaptability types and postpartum depressive symptoms.RESULTS After adjusting for age,education,occupation,gravidity,parity,and mode of delivery,disengaged[adjusted odds ratio(AOR)=3.36,95%CI:1.91-5.91],and separated(AOR=1.97,95%CI:1.34-2.90)family cohesion types showed a higher risk of postpartum depression than the connection type,whereas the enmeshed type(AOR=0.38,95%CI:0.28-0.51)protected against postpartum depressive symptoms.Rigid(AOR=4.41,95%CI:3.02-6.43)and structured families(AOR=1.88,95%CI:1.34-2.63)had a higher risk of postpartum depressive symptoms than flexible families,whereas chaotic families(AOR=0.35,95%CI:0.24-0.51)protected against postpartum depressive symptoms.CONCLUSION Family cohesion and adaptability are influencing factors for postpartum depressive symptoms,with higher family cohesion and adaptability being associated with a lower risk of postpartum depressive symptoms.
文摘In the context of the COVID-19 pandemic and under the pressure of high competitiveness for higher education in China,junior high school students’mental health is facing greater challenges.Understanding the time allocation of study and sleep is necessary for developing effective prevention and treatment programs.Based on a survey of 31,057 junior high school students in 47 junior high schools in Gansu Province,China's Mainland,the study analyzed the associations of time spent on study and sleep with anxiety and depressive symptoms among junior high school students through chi-square test,ANOVA,logistic regression model and threshold regression model.It was found that 18.4%–21.1%of junior high school students had mild and above anxiety and depressive symptoms.Female junior high school students were more likely to have anxiety and depressive symptoms.In addition,time spent on study was significantly and positively associated with anxiety and depressive symptoms and time spent on sleep was significantly and negatively associated with anxiety and depressive symptoms.Late sleepers were more likely to suffer from anxiety and depressive tendencies.Reducing after-school study time appropriately and getting more sleep are beneficial in reducing anxiety and depression,but it is more important to ensure time of sleep.For the reduction of anxiety and depressive symptoms,the maximum time spent on study after school should not exceed 1.92 h,the minimum time spent on sleep at night should be more than 7 h and a 40-min lunch break should be guaranteed at noon.

文摘BACKGROUND Most of the recent research on nightmare distress and depressive symptoms has focused on adolescents and students,with less research on the nurse population.Emergency department nurses are at high risk for nightmare distress and depressive symptoms,but no studies have been conducted to explore the relationship between the two;thus,further investigation is needed.AIM To understand the relationship between nightmare distress and depressive symptoms among emergency department nurses in China.METHODS A convenience sampling method was used to select 280 emergency department nurses from nine provinces,including Jiangxi,Sichuan,Jiangsu,and Shanxi Provinces.The Chinese version of the Nightmare Distress Questionnaire and the Center for Epidemiological Studies Depression Scale(CES-D)were administered.RESULTS Emergency department nurses’nightmare distress scores were positively associated with depressive symptom scores(r=0.732),depressed affect(r=0.727),somatic symptoms(r=0.737),and interpersonal difficulty(r=0.647).Further multiple linear regression analyses showed that education level,work pressure,self-reported health,and CES-D scores were factors that influenced nightmare distress among Chinese emergency department nurses(P<0.05).CONCLUSION Nightmare distress is closely associated with depressive symptoms in Chinese emergency department nurses,and early intervention is recommended for professionals with this type of sleep disorder to reduce the occurrence of depressive symptoms.
文摘BACKGROUND Perimenopausal is the period when women's ovarian function begins to decline before and after menopause.During this period,women experience a series of mental state changes,such as decreased hormone levels,decreased libido,and even female sexual dysfunction(FSD)in severe cases,which reduces their quality of life.Factors affecting the occurrence of FSD include physiological and nonphysiological factors,among which physiological factors are uncontrollable.Therefore,it is particularly important to ascertain the related non-physiological factors that affect the occurrence of FSD for improving the quality of sexual life of perimenopausal women.AIM To investigate the mediating effect of depressive mood and body image on menopausal symptoms and sexual function in perimenopausal women.METHODS A total of 186 perimenopausal women were enrolled between January 2019 and January 2021 and divided into the FSD(134 cases)and control(52 cases)groups based on the presence and absence of FSD.Clinical data were compared between the two groups.FSD-related factors were analyzed using logistic regression analysis.Hamilton Depression Scale(HAMD),Body Image Scale(BIS),and Menopause Rating Scale(MRS)scores were compared among women with different FSD scores.The correlation of the MRS score with the BIS and HAMD scores and the mediating effect of the BIS and HAMD scores on the MRS score and female sexual function index(FSFI)were analyzed.RESULTS The HAMD and BIS scores were higher in the FSD group than in the control group,and the difference in monthly income between the two groups was statistically significant(all P<0.05).Monthly income of<2000 yuan[odds ratio(OR)=26.586,P=0.000],BIS score(OR=1.590,P=0.000),and HAMD score(OR=1.884,P=0.000)were independent risk factors for FSD.MRS scores were positively correlated with BIS and HAMD scores(r=0.358 and 0.244,P=0.000 and 0.001,respectively)and negatively correlated with FSFI scores(r=-0.433,P=0.000).Body image and depressive mood had partial mediating effects,accounting for 39.90%of the total effect.CONCLUSION Depression and body image play mediating roles between menopausal symptoms and sexual function in perimenopausal women.
文摘BACKGROUND Our study expand upon a large body of evidence in the field of neuropsychiatric imaging with cognitive,affective and behavioral tasks,adapted for the functional magnetic resonance imaging(MRI)(fMRI)experimental environment.There is sufficient evidence that common networks underpin activations in task-based fMRI across different mental disorders.AIM To investigate whether there exist specific neural circuits which underpin differ-ential item responses to depressive,paranoid and neutral items(DN)in patients respectively with schizophrenia(SCZ)and major depressive disorder(MDD).METHODS 60 patients were recruited with SCZ and MDD.All patients have been scanned on 3T magnetic resonance tomography platform with functional MRI paradigm,comprised of block design,including blocks with items from diagnostic paranoid(DP),depression specific(DS)and DN from general interest scale.We performed a two-sample t-test between the two groups-SCZ patients and depressive patients.Our purpose was to observe different brain networks which were activated during a specific condition of the task,respectively DS,DP,DN.RESULTS Several significant results are demonstrated in the comparison between SCZ and depressive groups while performing this task.We identified one component that is task-related and independent of condition(shared between all three conditions),composed by regions within the temporal(right superior and middle temporal gyri),frontal(left middle and inferior frontal gyri)and limbic/salience system(right anterior insula).Another com-ponent is related to both diagnostic specific conditions(DS and DP)e.g.It is shared between DEP and SCZ,and includes frontal motor/language and parietal areas.One specific component is modulated preferentially by to the DP condition,and is related mainly to prefrontal regions,whereas other two components are significantly modulated with the DS condition and include clusters within the default mode network such as posterior cingulate and precuneus,several occipital areas,including lingual and fusiform gyrus,as well as parahippocampal gyrus.Finally,component 12 appeared to be unique for the neutral condition.In addition,there have been determined circuits across components,which are either common,or distinct in the preferential processing of the sub-scales of the task.CONCLUSION This study has delivers further evidence in support of the model of trans-disciplinary cross-validation in psychiatry.

文摘Background:Zuojin Pill(ZJP)is a classic Chinese herbal prescription with good efficacy in the treatment of Anxiety disorder(AD)and Major depressive disorder(MDD).Nevertheless,the potential mechanisms of ZJP remain unclear.Based on network pharmacology and molecular docking methods,this study aims to elucidate the possible mechanism of ZJP in the treatment of AD and MDD.Methods:The components and targets of Rhizoma Coptidis and Fructus Evodiae were collected from TCMSP,ETCM,HERB,SWISSADME and STITCH databases.The disease targets related to MDD and AD were collected from DISGENET,GENECARDS and OMIM databases.Protein-protein interaction network was constructed by STRING database,GO and KEGG enrichment analysis was performed by METASCAPE database,and“drugs-components-targets network”was constructed by Cytoscape software.Molecular docking verification was performed by Sailvina2.0 software.Results:ZJP may act on AKT1,IL6,TNF and other targets through caffeine,isorhamnetin,berberine and other components,regulating the Inflammatory mediator regulation of TRP channels,Serotonergic synapse,Dopaminergic synapse,PI3K/AKT signaling pathway,and other pathways.The results of molecular docking showed that berberine had the best binding activity with the core target.Conclusion:ZJP can exert anti-anxiety and anti-depression effects through multiple components,multiple targets and multiple pathways.
文摘Introduction Major depressive disorder(MDD)manifests by persistent depressed mood,anhedonia,changes in sleep and appetite,fatigue,guilt as well as hopelessness and suicidality.1 MDD is quite prevalent and remains a leading cause of disease burden worldwide.2 Antidepressants in combination with psychotherapies are helpful but do not work for all persons with MDD.
文摘BACKGROUND Various immune-mediated inflammatory diseases consisting of inflammatory bowel disease(IBD)and rheumatoid arthritis(RA),are found to have a substantial societal burden,increased healthcare costs,and progressive disability.Studies suggest that patients with vs without comorbid depression have a more significant disability,a lower likelihood of remission,and reduced adherence to therapy.Elevated interleukin(IL)-1β,tumor necrosis factor-α,and IL-6 contribute to developing depression by the impaired physiological responses to stress,resulting in increased pain,fever,fatigue,and lack thereof of interest,and thus poor long-term outcomes.This study emphasizes the timely recognition of the prevalence of major depressive disorder(MDD)in patients with RA and IBD combined,thus preventing disability.AIM To identify the prevalence level and temporal trends of depression in hospitalized IBD-RA patients.METHODS All adult hospitalized patients from January 2000 to December 2019 in the nationwide inpatient sample(NIS)were captured.The study population included all patients with a primary or secondary IBD-RA overlap disease using corresponding international classification of diseases(ICD)-9 and ICD-10 codes.IBD includes Crohn’s disease and ulcerative colitis.The study population was divided into IBD-RA without MDD(controls)and IBD-RA with MDD(cases).For group comparison between MDD vs no MDD,we used Student’s t-test for continuous variables and RaoScott Chi-square tests for categorical variables.For univariate analyses,we used logistic regression,and for multivariate analysis,we used a weighted multi-level mixed-effects model.We attested all hypotheses with two-tailed significance level of 0.05(P<0.05 was considered significant).The outcome is to examine the temporal trends and prevalence of depression in patients with IBD-RA by gender,race,and age.RESULTS A total of 133315 records were identified with IBD-RA overlap,of which 26155 patients(19.62%)had MDD.Among the IBD-RA patients,those who had MDD were younger[mean age of 56 years(SD±15)]to IBD-RA without MDD patients with a P<0.0001,more females(80%among cases vs 73%among controls)than males with a P<0.0001,frequent in the white race(79%among cases vs 73%among controls)than black race.Over the 19 years,the number of patients with MDD in IBDRA increased from 153(the year 2000)to 2880(the year 2019)in weighted NIS,representing a 1782%increase compared to the year 2000 with a P<0.001.Factors associated with higher MDD included younger age,female gender,white race,alcohol,opioids,esophageal disorders,peptic ulcer disease,chronic pancreatitis,paralysis,dementia,menopausal disorders,obesity,nutritional deficiencies,diabetes mellitus with chronic complications,and osteoarthritis.CONCLUSION There is a rise in the prevalence of depression in younger patients with IBD-RA combined compared to their counterparts.These patients are also at higher risk for the increased cost of care and poor treatment compliance.It is crucial to educate the involved clinicians to identify the early signs and symptoms of depression in patients with IBD or RA or IBD-RA combined and treat them to have a better overall prognosis.
文摘This study aimed to examine the associations between lifestyle behaviors and depressive symptoms in adolescents.Self-reported data from the 2019 Youth Risk Behavior Survey(YRBS)was analyzed.Depressive symptoms were set as the outcome variable.Movement variables(physical activity,muscle-strengthening exercise,physical education attendance,sports team participation,television watching,video or computer games,and sleep),eating behaviors(fruit intake,vegetable intake,milk intake,and eating breakfast or not),and substance use(alcohol use and cigarette use)were included as explanatory variables.Binary logistic regression was used to explore the asso-ciations between lifestyle behaviors and depressive symptoms after adjusting for sex,age,grade,race,and weight status.Of 13,677 participants who completed the investigation,girls were more than boys(50.3%vs.48.6%).The proportion of participants in grades 9,10,11,and 12 was 26.6,27.2,24.3,and 20.8,respectively.Of them,the prevalence of depressive symptoms was 36.0%(weighted%:36.7%[35.1%,38.3%]).Among all the lifestyle behaviors included,participating in no sports teams(OR=1.53[1.32,1.77]),spending more than 2 h in video or computer games(OR=1.64[1.40,1.92]),sleeping less than 8 h nightly(OR=1.79[1.45,2.20]),not eating breakfast(OR=1.56[1.37,1.78]),alcohol use(OR=1.74[1.49,2.02]),and cigarette use(OR=1.83[1.42,2.37])were associated with higher odds of depressive symptoms.To reduce depressive symptoms in adolescents,interventions can consider encouraging adolescents to engage in team sports activity,limit time for video or com-puter games,sleep enough,regularly eat breakfast,and avoid using alcohol and cigarette.Future studies are encouraged to verify our researchfindings by using a more improved study design.

文摘Objective:To investigate the effect of electroacupuncture on CREB/BDNF/TrkB signaling pathway in hippocampus of depressed rats.Methods:The depression rat model was established by chronic unpredictable stress(CUMS)combined with solitary rearing.The rats were randomly divided into blank group,model group,electroacupuncture group and fluoxetine group,with 10 rats in each group.In the electroacupuncture group,‘Baihui',‘Shenting',‘Hegu'and‘Taichong'were selected.Acupuncture was performed 1 h before modeling every day,and the needles were retained for 20 min,once a day for 21 d.Fluoxetine group:Fluoxetine(10 mg/kg,1 mg/mL)was intragastrically administered 1 h before modeling for 21 d.The changes of body weight,the number of standing and the distance of movement in open field test,the immobility time of forced swimming test were observed.The contents of 5-HT,DA and NE in serum were detected by ELISA.The expression of BDNF,CREB and TrkB in hippocampus was detected by Western blot.The expression of BDNF and CREB mRNA in hippocampus was detected by real-time fluorescence quantitative PCR.Results:After modeling intervention:Compared with the blank group,the body weight,the number of standing,the distance of movement,the content of serum 5-HT,DA and NE,the expression of BDNF,CREB and TrkB in the hippocampus of the model group were significantly decreased(all P<0.01),and the immobility time was significantly increased(P<0.01).Compared with the model group,the body weight,the number of standing,the distance of movement,the content of 5-HT,DA and NE in serum,the expression of BDNF,CREB and TrkB in hippocampus were significantly increased(all P<0.05),and the immobility time was significantly decreased(P<0.05)in the EA group and fluoxetine group.There was no significant difference between the electroacupuncture group and the fluoxetine group(P>0.05).Conclusion:EA can significantly improve the symptoms of depression in rats,and its mechanism may be related to the regulation of BDNF/TrkB/CREB signaling pathway-related proteins in hippocampus,increase the content of monoamine neurotransmitters 5-HT,NE and DA,resulting in antidepressant effect.
文摘Objective:We examined the effects of mindfulness-based interventions(MBIs)on depressive symptoms in patients with substance use disorders(SUDs)and explored the moderating effects of participant,method,and intervention characteristics.Methods:We systematically searched 8 databases from their inception till November 2021.The inclusion criteria were primary studies evaluating MBIs in patients with SUDs with depression measured as an outcome,those including a control group,and those written in English.We used a random-effects model to compute effect sizes(ESs)using Hedges’g,a forest plot,and Q and I2 statistics as measures of heterogeneity;we also examined moderator analyses.Results:Nineteen studies included 1352 participants(age:38.6±7.0 years).Overall,MBIs showed significantly improved depression(g=0.67,95%confidence interval[CI]:0.29,1.05,I2=89%)compared to controls.With regard to moderators,providing MBIs as an individual plus group intervention had a greater effect(g=2.13)on reducing depressive symptoms than providing MBIs as a group intervention(g=0.64)or an individual intervention only(g=0.33,P=0.034).Using concealed allocation tended to reduce depressive symptoms(g=1.22)as compared to not using concealed allocation(g=0.48,P=0.086).No other quality indicators were demonstrated to have a moderating influence on the value of the ES.Conclusions:MBIs improved depressive symptoms in patients with SUDs.MBIs might be used as an adjunctive or alternative to conventional treatment for depressed patients with SUDs.
