    During the past decade, burnout syndrome has been widely discussed not only in the USA but also in Japan. To evaluate the state of "burnout," two major scales are available: the first is the Maslach Burnout Inventory (MBI) developed by C. Maslach and the other is the burnout scale by A. Pines. MBI is suggested to be independent of and incompatible with Pines' burnout scale, but, Pines' burnout scale is predominantly used in Japan, while both are used in the USA. Since hardly any studies of burnout using MBI have been made in Japan, we measured and analyzed MBI to evaluate the burnout state of doctors, nurses, caregivers, teachers and clerks who are engaged in "human services professions." The available data were subjected to factor analysis, reliability analysis and multiple regression analysis using Zung's Self-rating Depression Scale (SDS). The following results were obtained. 1) The factor analysis showed that the factor loading pattern was similar to that of Maslach's, but two different factors were emerged in addition to the standard factors in the intensity subscale. 2) In the relationship with the state of depression, burnout is closely related to depression but simultaneously has its own factors. This suggest that burnout is not a subtype of the depressive state.

    The purpose of the study was to elucidate characteristics of depression in Parkinson's disease (PD). Fifty-eight PD patients were evaluated with Zung's Self-Rating Depression Scale (SDS) and the Unified Parkinson's Disease Rating Scale (UPDRS). Scores for "suicidal ideation" on the SDS correlated with posture and gait disturbances on the UPDRS. Twenty-six patients with spinocerebellar degeneration (SCD) were also evaluated with the SDS. SDS scores for "indecisiveness" and "constipation" were significantly higher in PD patients than SCD patients. Our results suggest that depression is common in disabled persons but PD patients might have a characteristic clinical presentation.

    Stöber's Social Desirability Scale (SDS-17) was examined psychometrically in 5 samples (N=2817) from Austria, Canada, and the U.S.A. Rasch and Mokken scaling analyses attested the SDS-17 is not strictly unidimensional. Age, agreeableness, and conscientiousness were notable positive correlates of SDS-17 scores. There were signs of non-normal score distributions, acquiescence bias, and sex and country differences (higher scores among Austrians than North Americans). Items with higher ratings of social desirability according to previous research were particularly prone to show sex effects. The SDS-17 appears suitable in cross-cultural settings, but may benefit from substituting its true-false response format with a rating-scale format. A formative-indicators view regarding the social desirability construct and the SDS-17 is discussed.

    Large-scale scientific applications typically write their data to parallel file systems with organizations designed to achieve fast write speeds. Analysis tasks frequently read the data in a pattern that is different from the write pattern, and therefore experience poor I/O performance. In this paper, we introduce a prototype framework for bridging the performance gap between write and read stages of data access from parallel file systems. We call this framework Scientific Data Services, or SDS for short. This initial implementation of SDS focuses on reorganizing previously written files into data layouts that benefit read patterns, and transparently directs read calls to the reorganized data. SDS follows a client-server architecture. The SDS Server manages partial or full replicas of reorganized datasets and serves SDS Clients' requests for data. The current version of the SDS client library supports HDF5 programming interface for reading data. The client library intercepts HDF5 calls and transparently redirects them to the reorganized data. The SDS client library also provides a querying interface for reading part of the data based on user-specified selective criteria. We describe the design and implementation of the SDS client-server architecture, and evaluate the response time of the SDS Server and the performance benefits of SDS.

    Full Text Available Abstract Background Missing data present a challenge to many research projects. The problem is often pronounced in studies utilizing self-report scales, and literature addressing different strategies for dealing with missing data in such circumstances is scarce. The objective of this study was to compare six different imputation techniques for dealing with missing data in the Zung Self-reported Depression scale (SDS. Methods 1580 participants from a surgical outcomes study completed the SDS. The SDS is a 20 question scale that respondents complete by circling a value of 1 to 4 for each question. The sum of the responses is calculated and respondents are classified as exhibiting depressive symptoms when their total score is over 40. Missing values were simulated by randomly selecting questions whose values were then deleted (a missing completely at random simulation. Additionally, a missing at random and missing not at random simulation were completed. Six imputation methods were then considered; 1 multiple imputation, 2 single regression, 3 individual mean, 4 overall mean, 5 participant's preceding response, and 6 random selection of a value from 1 to 4. For each method, the imputed mean SDS score and standard deviation were compared to the population statistics. The Spearman correlation coefficient, percent misclassified and the Kappa statistic were also calculated. Results When 10% of values are missing, all the imputation methods except random selection produce Kappa statistics greater than 0.80 indicating 'near perfect' agreement. MI produces the most valid imputed values with a high Kappa statistic (0.89, although both single regression and individual mean imputation also produced favorable results. As the percent of missing information increased to 30%, or when unbalanced missing data were introduced, MI maintained a high Kappa statistic. The individual mean and single regression method produced Kappas in the 'substantial agreement' range

    Full Text Available Abstract Background The prevalence of major depressive disorder (MDD is highest in working age people and depression causes significant impairment in occupational functioning. Work productivity and work absence should be incorporated into clinical assessments but currently available scales may not be optimized for clinical use. This study seeks to validate the Lam Employment Absence and Productivity Scale (LEAPS, a 10-item self-report questionnaire that takes 3-5 minutes to complete. Methods The study sample consisted of consecutive patients attending a Mood Disorders outpatient clinic who were in full- or part-time paid work. All patients met DSM-IV criteria for MDD and completed during their intake assessment the LEAPS, the self-rated version of the Quick Inventory for Depressive Symptomatology (QIDS-SR, the Sheehan Disability Scale (SDS and the Health and Work Performance Questionnaire (HPQ. Standard psychometric analyses for validation were conducted. Results A total of 234 patients with MDD completed the assessments. The LEAPS displayed excellent internal consistency as assessed by Cronbach's alpha of 0.89. External validity was assessed by comparing the LEAPS to the other clinical and work functioning scales. The LEAPS total score was significantly correlated with the SDS work disability score (r = 0.63, p Conclusion The LEAPS displays good internal and external validity in a population of patients with MDD attending an outpatient clinic, which suggests that it may be a clinically useful tool to assess and monitor work functioning and productivity in depressed patients.

    Among various research strategies for depression, the cross-cultural approach is a useful tool to investigate depressive disorders. The Hamilton Rating Scale for Depression was applied to 130 depressed inpatients in France and Brazil. Items were factorized by principal component analysis with Varimax rotation using the Kaiser or simulation method for factor sorting. Three factors were obtained in France, and four in Brazil. The first factor includes the core symptoms of depression in both samples. Qualitative and quantitative differences appeared in the anxiety factor between Brazilian and French samples. Insomnia items appeared as another factor for both groups. A limitation of this study is that it was conducted with small inpatient samples. Principal component analysis of the Hamilton Rating Scale for Depression for depressive inpatients in these two countries showed a similar structure. Differences observed were in the way anxiety items were distributed.

    Full Text Available We assessed the concurrent validity of the Hospital Anxiety and Depression Scale (HADS and the Geriatric Depression Scale (GDS against the Hamilton Rating Scale for Depression (Ham-D in patients with Parkinson’ disease (PD. Forty-six non-demented PD patients were assessed by a neurologist on the Ham-D. Patients also completed four mood rating scales: the HADS, the GDS, the VAS and the Face Scale. For the HADS and the GDS, Receiver Operating Characteristics (ROC curves were obtained and the positive and negative predictive values (PPV, NPV were calculated for different cut-off scores. Maximum discrimination between depressed and non-depressed PD patients was reached at a cut-off score of 10/11 for both the HADS and the GDS. At the same cut-off score of 10/11 for both the HADS and the GDS, the high sensitivity and NPV make these scales appropriate screening instruments for depression in PD. A high specificity and PPV, which is necessary for a diagnostic test, was reached at a cut-off score of 12/13 for the GDS and at a cut-off score of 11/12 for the HADS. The results indicate the validity of using the HADS and the GDS to screen for depressive symptoms and to diagnose depressive illness in PD.

    According to Beck theory, dysfunctional attitude has a central role in emergence of depression. The aim of this study was to determine contributions of dysfunctional attitude and general health index to depression. In this case-control study, two groups of subjects participated. The first group consisted of 65 patients with major depression and dysthymic disorder, who were recruited from Noor and Navab Safavi Psychiatry Clinics in Isfahan. The control group was consisted of 65 non-patient individuals who were accompanied or relatives of the patients and was matched with them based on age, sex and education. Both groups completed 26-item Dysfunctional Attitude Scale (DAS-26) and 28-item General Health Questionnaire (GHQ-28). Logistic regression and correlation methods were applied for statistical analysis. Logistic regression analysis showed that by an increase of one level in categorized DAS-26 scores and one score in the physical symptoms, anxiety, social dysfunction and depression subscales of GHQ-28 the risk of depression increase by 6.8, 1.6, 1.9, 3.7, 4.78 times, respectively. Capability of dysfunctional attitude and general health subscales to predict depression supports the Beck's cognitive diathesis stress theory of depression that dysfunctional attitude may be a predisposing risk factor for depression.

    The New Multi-dimensional Depression Scale (NMDS) is one of the most comprehensive scales that measures depression symptoms in four domains, including emotional, cognitive, somatic, and interpersonal. This study aimed to evaluate the factor structure and psychometric properties of the NMDS in a group of Iranian inpatients with Major Depressive Disorder (MDD). At first, the scale was translated into Persian and used as part of a battery consisting of the Beck Depression Inventory-II (BDI-II), Oxford Happiness Inventory (OHI), Beck Anxiety Inventory (BAI), and Short Form Health Survey (SF-36). The battery was administered to 271 inpatients with MDD (90 men and 181 women) aged from 18 to 60 who had been referred to psychiatric hospitals in Tehran, Iran. Confirmatory factor analysis of the Persian version of the NMDS upheld its original four-factor structure. Moreover, the results showed its good internal consistency (Cronbach's alpha coefficient ranging from 0.70 for the emotional subscale to 0.83 for the interpersonal subscale). In addition, the NMDS scores were correlated with other constructs in empirically and theoretically expected ways, which provides evidence for the convergent (positive significant relationships with anxiety and cognitive and somatic-affective symptoms of depression) and divergent (negative significant relationships with happiness and mental health and physical health) validity of the scale. These findings supported the Persian version of the NMDS as a reliable and valid measure for the assessment of depression symptoms in patients with MDD.

    Full Text Available Background: India is in the process of rapid demographic progression of increased life expectancy and aging with geriatric population of 7.2 percent which is estimated to rise to 20 percent in 2050. With increasing geriatric population elderly with dementia and associated depressive illness are expected to rise in number to almost an epidemic. Among the morbidity encountered in elderly, depressive disorders are common. Aim & Objectives: The present study was conducted with the objective to assess the extent and degree of depression in elderly, and study some correlates associated with depression in them. Material & Methods: The study was carried out at geriatric clinic of Dr. D. Y. Patil Medical College, Pune under the guidance of department of community medicine. Methodology:The randomly selected elderly above the age of 60 years attending the clinic and willing to participate in study were administered the questionnaire of Geriatric Depression Scale (GDS, scores were given, based on which the subjects were categorized as mild, moderate and severe. Those with score >5 were considered as suggestive of depression and some factors studied were analysed to find out their association with depression. Results: It was revealed that the proportion of elderly having depression was 52.4% with 84.6% of depressed in age group of 76-80 years. Moderate to severe type was more commonly seen in illiterate; however some degree of depression was present in all elderly irrespective of literacy status. Moderate to severe type was seen more commonly in elderly living in nuclear families (23.8%, and living alone (33.3%. Thus more than half of elderly studied were having depression, and it was observed that as the age advanced the degree of depression significantly increased. Some of the factors studied like low education status, poor economic status, nuclear family status, single status, loneliness, were associated with depression. The GDS Scale can be considered as

    The predictive value of early functional improvement for treatment success at week 8 was assessed in a pooled analysis in patients with major depressive disorder (MDD). Data were pooled from 7 double-blind studies in adult patients with MDD randomly assigned to desvenlafaxine 50 mg/d or placebo. Four levels of treatment success were determined at week 8 for patients with baseline Sheehan Disability Scale (SDS) score > 12 (N = 2156): functional response (SDS ≤12 and ≥50% improvement in SDS), functional/depression response (SDS ≤12 and ≥50% improvement in both SDS and 17-item Hamilton Rating Scale for Depression [HAM-D17] score), functional remission (SDS desvenlafaxine (40%, 32%, 23%, 15%, respectively) vs placebo (31%, 22%, 17%, 10%; all P ≤ 0.002). Early change in SDS was a highly significant predictor of functional response/remission (ORs, 0.958-0.970; all P desvenlafaxine 50 mg/d is predictive of treatment success.

    Full Text Available The purpose of this study is to compare discrimination power of original and reconstructed version of Hamilton’s depression scale in separation of depressive vs. anxious patients and to suggest some possibilities which offer ROC analysis. The subjects of the study were 119 patients of Psychiatric clinic in Novi Sad. 67 of them were diagnosed with some of the forms of affective disorders and 52 with an anxious-phobic diagnosis. Results of ROC analysis suggest that both instruments can be used in distinguishing depressive from anxious patients, but reconstructed version shows greater sensitivity and specificity with optimal cut-off score. It also has more significant AUC, which refers to probability of prediction on the basis of the whole spectrum of the results. These data is commented in relation with current debates, between unitaristic and pluralistic oriented authors, about the nature of the anxious-depression relationship.

    The consistency of the Hamilton Depression Scale (HDS) as a measure of the severity of depressive states has been examined when the scale was used weekly during a trial when imipramine. By use of logistic models (Rasch) the consistency of the HDS has been considered across patient-variables as age, sex, plasma levels of imipramine, and diagnosis. The results showed that the original 17-item HDS was without adequate consistency, i.e. the total score of the sample of items was no one-dimensional measure of depressive states. However, a melancholia subscale of the HDS contained items the total of which can be used to compare patients quantitatively, although in some part of the analysis one of these items showed ceiling effect. It was concluded that the melancholia subscale (containing the items depressed mood, guilt, work and interests, retardation, psychic anxiety, and general somatic symptoms) can form the basis for further improvements in the field of quantitative rating scales for depressive states.

    The Hospital Anxiety and Depression Scale (HADS) is a prolifically used scale of anxiety and depression. The original bidimensional anxiety-depression latent structure of the HADS has come under significant scrutiny, with previous studies revealing one-, two-, three- and four-dimensional structures. The current study examines the latent structure of the HADS using a non-parametric item response theory method. Using data conglomerated from four independent studies of cardiovascular disease employing the HADS (n=893), Mokken scaling procedure was conducted to assess the latent structure of the HADS. A single scale consisting of 12 of 14 HADS items was revealed, indicating a unidimensional latent HADS structure. The HADS was initially intended to measure mutually exclusive levels of anxiety and depression; however, the current study indicates that a single dimension of general psychological distress is captured.

    Full Text Available This study’s objective was to analyze the diagnostic capabilities of a depression screening scale. For that, this scale was administered along with two diagnostic instruments, namely, the structured clinical interview from the DSM-IV (SCID-CV and the Hamilton Depression Scale (HAM-D, which are considered to be the gold standard for diagnosing depressive disorders. Participants were 22 subjects diagnosed by psychiatrists with Major Depressive Disorder. The EBADEP-A correctly identified cases of depression, showing a high correlation with the HAM-D, which indicates the scale correctly captures most depressive symptoms, even though it was initially used as a depression-screening tool.

    Full Text Available The Overall Depression Severity and Impairment Scale (ODSIS is a brief, five-item measure for assessing the frequency and intensity of depressive symptoms, as well as functional impairments in pleasurable activities, work or school, and interpersonal relationships due to depression. Although this scale is expected to be useful in various psychiatric and mental health settings, the reliability, validity, and interpretability have not yet been fully examined. This study was designed to examine the reliability, factorial, convergent, and discriminant validity of a Japanese version of the ODSIS, as well as its ability to distinguish between individuals with and without a major depressive disorder diagnosis.From a pool of registrants at an internet survey company, 2830 non-clinical and clinical participants were selected randomly (619 with major depressive disorder, 619 with panic disorder, 576 with social anxiety disorder, 645 with obsessive-compulsive disorder, and 371 non-clinical panelists. Participants were asked to respond to the ODSIS and conventional measures of depression, functional impairment, anxiety, neuroticism, satisfaction with life, and emotion regulation.Exploratory and confirmatory factor analysis of three split subsamples indicated the unidimensional factor structure of ODSIS. Multi-group confirmatory factor analysis showed invariance of factor loadings between non-clinical and clinical subsamples. The ODSIS also showed excellent internal consistency and test-retest intraclass correlation coefficients. Convergence and discriminance of the ODSIS with various measures were in line with our expectations. Receiver operating characteristic curve analyses showed that the ODSIS was able to detect a major depressive syndrome accurately.This study supports the reliability and validity of ODSIS in a non-western population, which can be interpreted as demonstrating cross-cultural validity.

    Objective Previous studies of the Depression and Somatic Symptoms Scale (DSSS), a free scale, have been based on the classical test theory, and the construct validity and dimensionality of the DSSS are as yet uncertain. The aim of this study was to use Mokken scale analysis (MSA) to assess the dimensionality of the DSSS. Methods A sample of 214 psychiatric outpatients with mood and anxiety disorders were enrolled at a medical center in Taiwan (age: mean [SD] =38.3 [10.5] years; 63.1% female) and asked to complete the DSSS. MSA was used to assess the dimensionality of the DSSS. Results All 22 items of the DSSS formed a moderate unidimensional scale (Hs=0.403), supporting its construct validity. The DSSS was divided into 4 subscales (Hs ranged from 0.35 to 0.67), including a general somatic scale (GSS), melancholic scale (MS), muscular pain scale (MPS), and chest symptom scale (CSS). The GSS is a weak reliable Mokken scale; the other 3 scales are strong reliable Mokken scales. Conclusion The DSSS is a psychometrically sound measure of depression and somatic symptoms in adult psychiatric outpatients with depression or anxiety. The summed score of the DSSS and its 4 subscales are valid statistics. Further research is required for replication of the 4 subscales of the DSSS. PMID:28182138

    To explore through literature review the appropriateness of three common tools for use by community nurses to screen war veteran and war widow(er) clients for depression, anxiety and post-traumatic stress disorder. War veterans and, to a lesser extent, war widow(er)s, are prone to mental health challenges, especially depression, anxiety and post-traumatic stress disorder. Community nurses do not accurately identify such people with depression and related disorders although they are well positioned to do so. The use of valid and reliable self-report tools is one method of improving nurses' identification of people with actual or potential mental health difficulties for referral to a general practitioner or mental health practitioner for diagnostic assessment and treatment. The Geriatric Depression Scale, Depression Anxiety Stress Scales and Post-traumatic Stress Disorder Checklist are frequently recommended for mental health screening but the appropriateness of using the tools for screening war veteran and war widow(er) community nursing clients who are often aged and have functional impairment, is unknown. Systematic review. Current literature informs that the Geriatric Depression Scale accurately predicts a diagnosis of depression in community nursing cohorts. The three Depression Anxiety Stress Scales subscales of depression, anxiety and stress are valid; however, no studies were identified that compared the performance of the Depression Anxiety Stress Scales in predicting diagnoses of depression or anxiety. The Post-traumatic Stress Disorder Checklist predicts post-traumatic stress disorder in community cohorts although no studies meeting the selection criteria included male participants. This review provides recommendations for the use of the Geriatric Depression Scale, Depression Anxiety Stress Scales and The Post-traumatic Stress Disorder Checklist based on examination of the published evidence for the application of these screening tools in samples

    Full Text Available Aim. The aim of this study was to adapt the Quality of Life in Depression Scale to Polish conditions. The scale determines the quality of life, defined in terms of the concept of needs, and focuses on patients with depressive disorders. Since its basic version has been developed, the tool was adapted in many countries, also outside Europe.Method. The adaptation procedure included the translation of the original version into Polish, followed by the English retranslation, and was performed by four independent, qualified translators. The final Polish version was verified during a pilot study.Results. This pilot study confirmed high reliability of the Polish version of Quality of Life in Depression Scale.Conclusion. The Quality of Life in Depression Scale (QLDS can be considered an interesting tool in view of its broad theoretical background, and a simple procedure to complete during a clinical evaluation. The use of a specialist translation procedure, and the results of our pilot study suggest that the QLDS can be used in further research, both when evaluating a clinical population and when dealing with individual patients.

    The Techniques for Overcoming Depression (TOD) questionnaire assesses the frequency with which patients being treated for depression use cognitive-behavioral techniques in daily life. This study examined its latent structure, reliability and concurrent validity in depressed cardiac patients. The TOD was administered at the initial and final treatment sessions in three trials of cognitive behavior therapy (CBT) (n = 260) for depression in cardiac patients. Mokken scaling was used to determine its dimensionality. The TOD is unidimensional in depressed cardiac patients, both at the initial evaluation (H = .46) and the end of treatment (H = .47). It is sensitive to change and the total score correlates with therapist ratings of the patient's socialization to CBT (r=.40, povercoming depression in cardiac patients. Studies of the TOD in other depressed patient populations are needed.

    High rates of anxiety and depression are reported among youth with autism spectrum disorders. These conditions are generally assessed using measures validated for typically developing youth. Few studies have investigated their validity for autism spectrum disorders, which is crucial for accurate assessment and the provision of proper treatment. The Revised Children's Anxiety and Depression Scale was evaluated with 67 youth with autism spectrum disorders to examine its utility in measuring anxiety and depression in this population. Parents and children (aged 11-15 years) referred to a multisite intervention study completed the Pediatric Anxiety Rating Scale, Multidimensional Anxiety Scale for Children, Anxiety Disorders Interview Schedule, Child Behavior Checklist, and Revised Children's Anxiety and Depression Scale. Results suggest acceptable internal consistency of the Revised Children's Anxiety and Depression Scale. Modest convergent validity was found among the Revised Children's Anxiety and Depression Scale and other standardized measures of anxiety and depression. There were stronger correlations between Revised Children's Anxiety and Depression Scale Total scores and subscales of measures expected to correlate significantly than those not expected to correlate. One exception was a significant association between the Revised Children's Anxiety and Depression Scale and Child Behavior Checklist Attention subscale, calling into question the divergent validity in separating anxiety from attention problems. Overall, results suggest preliminary support for the Revised Children's Anxiety and Depression Scale in youth with high-functioning autism spectrum disorders.

Methods we surveyed 1122 mothers and 499 fathers who were assessed using the EPDS during the first well-child visit. After 5 weeks, high scoring parents, completed a second EPDS. High scoring parents were examined by a psychiatrist who had to confirm the PD diagnosis. Results 26.6% of mothers and 12.6% of fathers at the first visit, 19.0% of mothers and 9.1% of fathers at the second visit, gained scores signaling the risk of PD. Four mothers and two fathers had confirmed PD diagnosis. Younger maternal age, non-Italian nationality and low socio-economic condition were related to higher EPDS scores. Conclusion PD is common in the average population. Using a simple and standardized instrument, pediatricians are able to detect parents with higher risk of suffering from PD.

    The Montgomery-Åsberg Depression Rating Scale (MADRS) is a widely used clinician-rated measure of depressive severity. Empirical support for the factor structure of the MADRS is mixed; further, the comparison of MADRS scores within and between patients requires the demonstration of consistent instrument properties. The objective of the current investigation was to evaluate MADRS factor structure as well as MADRS factorial invariance across time and gender. The MADRS was administered to 821 depressed outpatients participating in a large-scale effectiveness study of combined pharmacotherapy and psychotherapy for depression. Treatment outcome did not differ across treatment groups. Factor structure and invariance was evaluated via confirmatory factor analysis. A four-factor model consisting of Sadness, Negative Thoughts, Detachment and Neurovegetative symptoms demonstrated a good fit to the data. This four-factor structure was invariant across time and gender. A hierarchical model, in which these four factors served as indicators of a general depression factor, was also supported. A limitation of the current study is the lack of comprehensive characterization of patient clinical features; results need to be replicated in more severely depressed or treatment refractory patients. Overall, evidence supported the use of the MADRS total score as well as subscales focused on affective, cognitive, social and somatic aspects of depression in male and female outpatients.

    Prospective evaluations of the associations between depressive symptoms and suicide deaths have been mainly performed in high-risk populations, such as individuals with psychiatric disorders or histories of self-harm. The purpose of this study was to prospectively examine whether more severe depressive symptoms assessed using the Geriatric Depression Scale (GDS) were associated with a greater risk of death from suicide in a general-risk population. A total of 113 478 men from the Korean Veterans Health Study (mean age, 58.9 years) who participated in a postal survey in 2004 were followed up for suicide mortality until 2010. Over 6.4 years of follow-up, 400 men died by suicide (56.7 deaths per 100 000 person-years). More severe depressive symptoms were associated with greater risk of suicide death (p for trend depression were 2.18 for mild depression, 2.13 for moderate depression, 3.33 for severe depression, and 3.67 for extreme depression. After adjusting for potential confounders, men with a potential depressive disorder had an approximate 90% higher mortality from suicide (adjusted HR, 1.92; 95% confidence interval [CI], 1.38 to 2.68; pdepression. Each five-point increase in the GDS score was associated with a higher risk of death by suicide (adjusted HR, 1.22; pDepressive symptoms assessed using the GDS were found to be a strong independent predictor of future suicide. However, the estimate of relative risk was weaker than would be expected based on retrospective psychological autopsy studies.

    Patients often experience 'preparatory-grief' as they cope with the dying process. Some may be depressed. The Terminally Ill Grief or Depression Scale (TIGDS), comprising grief and depression sub-scales, is a new self-report measure designed to differentiate between preparatory-grief and depression in adult inpatients. The initial 100-item inventory was assembled based on literature review, interviews with clinicians and dying patients and then shortened to 42 items based on consensus expert opinion. Validity and reliability were tested in a sample of 55 terminally ill adults. The consensus clinical opinion was used as the gold standard to differentiate between preparatory grief and depression. The intra-class correlation coefficient was high (it was calculated to estimate the test-retest reliability for the 47 patients who had completed the TIGDS twice--retest was administered 2 to 7 days after the initial test), ranging from 0.86 (grief) to 0.97 (depression). The validity of TIGDS was assessed using a receiver operating characteristic curve analysis, comparing the first test with the clinical criterion. The first and only variable and cut-point was the depression score (chi-square = 18.4, p depression = 3 cutoff score. The construct validity of the TIGDS was tested by comparing with the Hospital Anxiety and Depression Scale (HADS). The TIGDS depression subscale showed strong convergent validity and the TIGDS grief subscale showed strong discriminant validity with the HADS total score.

    The identification of anxiety and depressive disorders in tinnitus patients is important from a therapeutic point of view. We have addressed this question by investigating the screening performance of the Hospital Anxiety and Depression Scale (HAD) in a consecutive series of tinnitus patients (n = 82) without severe socially disabling hearing loss referred to an audiological clinic. The structured clinical interview for DSM-III criteria was used as the gold standard. Receiver operating characteristic (ROC) curves were used to compare the screening abilities of the HAD subscales for anxiety and depression and the total HAD Scale. The ROC analysis showed that the HAD Scale was better at detecting depression than anxiety disorders in tinnitus patients. The optimal cut-off score for the subscales was > or = 5 when we were screening for any anxiety or depressive disorder as well as for major depression. The performance of the HAD depression subscale was superior, especially when we were screening for major depression only (sensitivity 1.00; specificity 0.75). The findings of the study suggest that the HAD Scale is more useful for screening for depression than for anxiety disorders in tinnitus patients

    Full Text Available The identification of antenatal depression is critical but poorly conducted. The aim of this study was to construct a simplified depression survey scale and to verify its efficacy as a pre-screening for antenatal depression. A total of 494 pregnant women in the third trimester of gestation who had received antenatal care at Seoul St. Mary's Hospital from July 2009 to June 2010 were included. The Edinburgh Postnatal Depression Scale (EPDS questionnaire was completed by them. The subjects were randomly divided into two groups: 250 of training set and 244 of validation set. We designed a simplified questionnaire comprising two items of EPDS using the training set. We then validated its efficacy with the training set and reaffirmed the results with the validation set. The sum of item 5 (scare or panic and item 8 (sadness or misery explained 75.5% of the total score of the EPDS (AUC = 0.947. Using a score of 3 as a cut-off value of the simplified scale, sensitivity was 92.4% and specificity was 86.3%. The positive and negative predictive values were 56.2% and 98.4%, retrospectively. This study suggests that the simplified EPDS can be an efficient instrument to rule out depression during pregnancy.

    Comorbid depression and medical illness is associated with a number of adverse health outcomes such as lower medication adherence and higher rates of subsequent mortality. Reliable and valid psychological measures capable of detecting a range of depressive symptoms found in medical settings are needed. The Cardiac Depression Visual Analogue Scale (CDVAS) is a recently developed, brief six-item measure originally designed to assess the range and severity of depressive symptoms within a cardiac population. The current study aimed to further investigate the psychometric properties of the CDVAS in a general and medical sample. The sample consisted of 117 participants, whose mean age was 40.0 years (SD = 19.0, range 18-84). Participants completed the CDVAS, the Cardiac Depression Scale (CDS), the Depression Anxiety Stress Scales (DASS) and a demographic and health questionnaire. The CDVAS was found to have adequate internal reliability (α = .76), strong concurrent validity with the CDS (r = .89) and the depression sub-scale of the DASS (r = .70), strong discriminant validity and strong predictive validity. The principal components analysis revealed that the CDVAS measured only one component, providing further support for the construct validity of the scale. Results of the current study indicate that the CDVAS is a short, simple, valid and reliable measure of depressive symptoms suitable for use in a general and medical sample.

    Full Text Available Context: Though common, depressive disorders often remain undetected in late life. Aim: To examine the usefulness of Center for Epidemiologic Studies Depression (CES-D for identifying depression among older people. Settings and Design: Community resident older people (aged 65 years or more, were evaluated by clinicians trained in psychiatry, as part of a cross-sectional study of late-life depression. Assessments were done in the community. Methods and Material: The participants were assigned ICD-10 diagnoses and assessed using Montgomery-Asberg Depression Rating Scale (MADRS and CES-D. A short version of CES-D with 10 items, translated to the local language Malayalam, was used. Statistical Analysis: The sensitivity and specificity of CES-D was evaluated against ICD-10 clinical diagnosis of depression. The correlation of CES-D and MADRS was assessed using Pearson correlation coefficient. Results: 220 consenting adults from 3 wards of the Panchayath were assessed. On analysis of the Receiver Operating Characteristic (ROC curve of CES-D scores in relation to clinical diagnosis, the large Area Under Curve (AUC showed efficient screening and a cut off score of 4 in CES-D had a sensitivity of 97.7% and a specificity of 79.1% for depression. There was also good correlation between the MADRS and CES-D scores (0.838. Conclusion: CES-D is a short simple scale which can be used by health care professionals for detecting depression in older people in primary care settings.

    Full Text Available Abstract Background While it is recognised that depression is prevalent in Rheumatoid Arthritis (RA, recent studies have also highlighted significant levels of anxiety in RA patients. This study compared two commonly used scales, the Depression Anxiety and Stress Scale (DASS and the Hospital Anxiety and Depression Scale (HADS, in relation to their measurement range and cut points to consider the relative prevalence of both constructs, and if prevalence rates may be due to scale-specific case definition. Methods Patients meeting the criteria for RA were recruited in Leeds, UK and Sydney, Australia and asked to complete a survey that included both scales. The data was analysed using the Rasch measurement model. Results A total of 169 RA patients were assessed, with a repeat subsample, resulting in 323 cases for analysis. Both scales met Rasch model expectations. Using the 'possible+probable' cut point from the HADS, 58.3% had neither anxiety nor depression; 13.5% had anxiety only; 6.4% depression only and 21.8% had both 'possible+probable' anxiety and depression. Cut points for depression were comparable across the two scales while a lower cut point for anxiety in the DASS was required to equate prevalence. Conclusions This study provides further support for high prevalence of depression and anxiety in RA. It also shows that while these two scales provide a good indication of possible depression and anxiety, the estimates of prevalence so derived could vary, particularly for anxiety. These findings are discussed in terms of comparisons across studies and selection of scales for clinical use.

    BACKGROUND: The Major Depression Inventory (MDI) was developed to cover the universe of depressive symptoms in DSM-IV major depression as well as in ICD-10 mild, moderate, and severe depression. The objective of this study was to evaluate the standardization of the MDI as a depression severity......-IV major depression. The conventional VAS scores for no, mild, moderate, and severe depression were used for the standardization of the MDI. RESULTS: The inter-correlation for the MDI with the clinician ratings (VAS, MES, HAM-D17 and HAM-D6) increased over the rating weeks in terms of Pearson coefficients....... After nine weeks of therapy the coefficient ranged from 0.74 to 0.83. Using the clinician-rated VAS depression severity scale, the conventional MDI cut-off scores for no or doubtful depression, and for mild, moderate and severe depression were confirmed. CONCLUSIONS: Using the VAS as index of external...

    The Space Debris Sensor (SDS) is a NASA experiment scheduled to fly aboard the International Space Station (ISS) starting in 2018. The SDS is the first flight demonstration of the Debris Resistive/Acoustic Grid Orbital NASA-Navy Sensor (DRAGONS) developed and matured at NASA Johnson Space Center's Orbital Debris Program Office. The DRAGONS concept combines several technologies to characterize the size, speed, direction, and density of small impacting objects. With a minimum two-year operational lifetime, SDS is anticipated to collect statistically significant information on orbital debris ranging from 50 microns to 500 microns in size. This paper describes the features of SDS and how data from the ISS mission may be used to update debris environment models. Results of hypervelocity impact testing during the development of SDS and the potential for improvement on future sensors at higher altitudes will be reviewed.

    Results from this randomized, placebo-controlled study of aripiprazole augmentation to antidepressant therapy (ADT) in Japanese patients with major depressive disorder (MDD) (the Aripiprazole Depression Multicenter Efficacy [ADMIRE] study) revealed that aripiprazole augmentation was superior to ADT alone and was well tolerated. In subgroup analyses, we investigated the influence of demographic- and disease-related factors on the observed responses. We also examined how individual symptom improvement was related to overall improvement in MDD. Data from the ADMIRE study were analyzed. Subgroup analyses were performed on the primary outcome measures: the mean change in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score from the end of selective serotonin reuptake inhibitor (SSRI)/serotonin norepinephrine reuptake inhibitor (SNRI) treatment to the end of the randomized treatment. Changes in the MADRS total scores were consistently greater with aripiprazole than placebo in each of the subgroups. Efficacy was not related to sex, age, number of adequate ADT trials in the current episode, MDD diagnosis, number of depressive episodes, duration of the current episode, age at first depressive episode, time since the first depressive episode, type of SSRI/SNRI, or severity at the end of SSRI/SNRI treatment phase. Compared to placebo, aripiprazole resulted in significant and rapid improvement on seven of the 10 MADRS items, including sadness. These post-hoc analyses indicated that aripiprazole was effective for a variety of Japanese patients with MDD who had exhibited inadequate responses to ADT. Additionally, we suggest that aripiprazole significantly and rapidly improved the core depressive symptoms. © 2014 The Authors.

    2010-01-01

    Full Text Available The construct of entrapment is used in evolutionary theory to explain the etiology of depression. The perception of entrapment can emerge when defeated individuals want to escape but are incapable. Studies have shown relationships of entrapment to depression, and suicidal tendencies. The aim of this study was a psychometric evaluation and validation of the Entrapment Scale in German (ES-D. 540 normal subjects completed the ES-D along with other measures of depressive symptoms, hopelessness, and distress. Good reliability and validity of the ES-D was demonstrated. Further, whereas entrapment originally has been regarded as a two-dimensional construct, our analyses supported a single-factor model. Entrapment explained variance in depressive symptoms beyond that explained by stress and hopelessness supporting the relevance of the construct for depression research. These findings are discussed with regard to their theoretical implications as well as to the future use of the entrapment scale in clinical research and practice.

    Objective This study was aimed at evaluating the diagnostic validity of the Korean version of the Clinically Useful Depression Outcome Scale (CUDOS) with varying follow-up in a typical clinical setting in multiple centers. Methods In total, 891 psychiatric outpatients were enrolled at the time of their intake appointment. Current diagnostic characteristics were examined using the Structured Clinical Interview for DSM-IV (41% major depressive disorder). The CUDOS was measured and compared with three clinician rating scales and four self-report scales. Results The CUDOS showed excellent results for internal consistency (Cronbach’s α, 0.91), test-retest reliability (patients at intake, r=0.81; depressed patients in ongoing treatment, r=0.89), and convergent and discriminant validity (measures of depression, r=0.80; measures of anxiety and somatization, r=0.42). The CUDOS had a high ability to discriminate between different levels of depression severity based on the rating of Clinical Global Impression for depression severity and the diagnostic classification of major depression, minor depression, and non-depression. The ability of the CUDOS to identify patients with major depression was high (area under the receiver operating characteristic curve=0.867). A score of 20 as the optimal cutoff point was suggested when screening for major depression using the CUDOS (sensitivity=89.9%, specificity=69.5%). The CUDOS was sensitive to change after antidepressant treatment: patients with greater improvement showed a greater decrease in CUDOS scores (pKorean version of the CUDOS is a very useful measurement for research and for clinical practice.

    2017-01-01

    Objectives Melancholic features of depression (MFD) seem to be a unidimensional group of signs and symptoms. However, little importance has been given to the evaluation of what features are related to a more severe disorder. That is, what are the MFD that appear only in the most depressed patients. We aim to demonstrate how each MFD is related to the severity of the major depressive disorder. Methods We evaluated both the Hamilton depression rating scale (HDRS-17) and its 6-item melancholic subscale (HAM-D6) in 291 depressed inpatients using Rasch analysis, which computes the severity of each MFD. Overall measures of model fit were mean (±SD) of items and persons residual = 0 (±1); low χ2 value; p>0.01. Results For the HDRS-17 model fit, mean (±SD) of item residuals = 0.35 (±1.4); mean (±SD) of person residuals = -0.15 (±1.09); χ2 = 309.74; p<0.00001. For the HAM-D6 model fit, mean (±SD) of item residuals = 0.5 (±0.86); mean (±SD) of person residuals = 0.15 (±0.91); χ2 = 56.13; p = 0.196. MFD ordered by crescent severity were depressed mood, work and activities, somatic symptoms, psychic anxiety, guilt feelings, and psychomotor retardation. Conclusions Depressed mood is less severe, while guilt feelings and psychomotor retardation are more severe MFD in a psychiatric hospitalization. Understanding depression as a continuum of symptoms can improve the understanding of the disorder and may improve its perspective of treatment. PMID:28114341

    To determine which of three published models best characterizes the factor structure of the Portuguese version of the Depression Anxiety Stress Scales-21 and to assess its validity and reliability. Confirmatory factor analysis of Depression Anxiety and Stress Scale-21 for 1,297 adult, primary care outpatients (66.7% female, Mage = 48.57 years) comparing 3 models. The relationship between the Depression Anxiety Stress Scales-21 and the Positive and Negative Affect Schedule was analyzed. The correlated 3-factor model fit the data best. The scale demonstrated good internal consistency, with alpha scores of the subscales ranging from 0.836 to 0.897. Correlation with the Positive and Negative Affect Schedule was positive and moderate with the negative affect scale; it was negative and limited with the positive affect. These findings support the correlated 3-factor structure. The test demonstrated adequate reliability and construct validity, which supports its use for screening in primary care settings with Portuguese speakers.

    PURPOSE: The aim of this study was to investigate symptoms of depression and anxiety in the patients with oral squamous cell carcinoma (OSCC). METHODS: 76 patients with oral squamous cell carcinoma participated in this program. All patients were rated with the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS). The mean scores of SAS and SDS were compared to those scores of the Norm of Chinese people. In addition, the different treatment results of the patients with different levels of anxiety and depression were studied. Further, the number of patients of SAS, SDS with more than 50 score were compared between primary cancer patients and recurrent cancer patients. RESULTS: The scores of SAS, SDS and the number of patients with more than 50 score in the patients group were obviously higher than those in Chinese Norm (P<0.01).The levels of anxiety and depression in 32 patients with recurrent cancer were more severe than those of 44 patients with primary cancer. The patients with anxiety and/or depression showed poor prognosis. CONCLUSION: Anxiety and depression are common symptoms in patients with OSCC and have negative effects on the prognosis, thus the psychological intervention for the patients must be carried out.

    We translated the Center for Epidemiologic Studies Depression (CES-D) Scale into Korean, paying careful attention to culturally different modes of expression of depressive feelings and thoughts. The final translated version (CES-D-K) was administered to 164 psychiatric patients and 464 normal subjects residing in the community. Reliability, validity, and the optimal cutoff point of this scale were estimated, including ROC analysis. The CES-D-K was reliable and valid for the Korean population. Two optimal cutoff points were suggested: 24/25, the point which best corresponded to the clinical diagnosis of depression, and 20/21, which most effectively detects and covers depressive symptoms during screening. The higher cutoff points than those in Western countries may be due to different ways of expression affect, especially the suppression of positive affect, in cultures based on Confucian ethics.

    2015-01-01

    INTRODUCTION: Depression and anxiety are common in Huntington's disease, a genetic neurodegenerative disorder. There is a need for measurement tools of mood to be validated within a Huntington's disease population. The current study aimed to analyze the factor structure of the Hospital Anxiety......, with two group factors, comprising four depression and four anxiety items, provided the best fit of the data. The salience of loadings on the bifactor model suggested that loadings were high on the general factor (accounting for 64% of the variance) and low on the group factors (21% for anxiety and 15......% for depression). CONCLUSIONS: The findings suggest that eight items from the scale perform well among the sample. Consistent with recent developments in modeling the Hospital Anxiety and Depression Scale, a bifactor interpretation for an eight-item version outperformed other extant models. Our findings provide...

    To examine the relationships between low-grade chronic depression, pain and personality traits among community-dwelling persons with traumatic spinal cord injury (TSCI), 111 male and 11 female TSCI persons were administered questionnaires including Self-rating Depression Scale (SDS) and measures of pain and other mental health items, and were followed-up two years later. Nineteen persons (15%) meeting the criteria for low-grade chronic depression (both SDS scores > or = 48) were identified, while 30% of the sample population consistently showed normal mood (both SDS scores pain and B type (emotionally labile, socially maladjusted, and extraverted personality characteristic) associated with lower IQ (90 and less) were significantly related to high SDS scores. However, age, sex, time-since-injury, levels of injury and marital status had no relationship with depression.

    Full Text Available This paper presents an empirical investigation to construct, to validate and to determine normalization factors associated with adolescents depression scale. The study is performed among 750 randomly selected guided and high school students, 364 male and 386 female, who live in city of Zanjan, Iran. Validity of Beck Depression Inventory (BDI, Validity of Simpson-Angus Scale (SAS and divergence validity of the Coopersmith self- esteem coefficients are 0.72, 0.37 and -0.71, respectively. Result suggests that adolescents’ depression test is a reliable and valid tool for assessing depression, with utility in both research and clinical settings, counseling centers. In addition, the results of correlation test indicate there are some meaningful differences between depression levels of female and male students. In fact, our survey indicates that female students have more depression than male students do (F-value = 33.06, Sig. = 0.000. In addition, there are some meaningful differences between depression levels in various educational levels (F-value = 8.59, Sig. = 0.000. However, the study does not find sufficient evidence to believe there is any meaningful correlation between educational backgrounds and gender.

    Full Text Available Surfactant films on solid surfaces have attracted much attention because of their scientific interest and applications, such as surface treatment agent, or for micro- or nano-scale templates for microfluidic devices. In this study, anionic surfactant sodium dodecyl sulfate (SDS solutions with various charged inorganic salts was spread on a glass substrate and dried to form an SDS thin film. Atomic force microscopy (AFM was employed to observe the micro-structure of the SDS thin film. The effects of inorganic salts on the morphology of the SDS film were observed and discussed. The results of experiments demonstrated that pure SDS film formed patterns of long, parallel, highly-ordered stripes. The existence of the inorganic salt disturbed the structure of the SDS film due to the interaction between the cationic ion and the anionic head groups of SDS. The divalent ion has greater electrostatic interaction with anionic head groups than that of the monovalent ion, and causes a gross change in the morphology of the SDS film. The height of the SDS bilayer measured was consistent with the theoretical value, and the addition of the large-sized monovalent ion would lead to lowering the height of the adsorbed structures.

    It has been suggested that mood disorders and depressive status may be accompanied by lowered zinc status in the body, and adequate consumption of zinc increases a general perceived well-being. The main objective of this study was to assess the correlation between serum zinc concentrations and dietary zinc intakes with depression scores in university female students. In the first phase, Beck's depression questionnaire was applied in a random sampling of 308 selected 20-25-year-old female students (one third of total students in Ahvaz Jondi-Shapour University of Medical Sciences Golestan dormitories) to assess the major depressive disorder (MDD) scales. Then, in the second phase, 23 students who identified as having moderate and severe depression were selected as the case group, and 23 healthy age matched were chosen as the controls. Each of them completed a 12-item semiquantitative food frequency questionnaire containing the main food sources of zinc in the usual dietary patterns and also a 24-h food recall questionnaire to assure the daily zinc intakes. Daily zinc intakes were obtained by multiplying each portion size by its zinc content using food tables. A 5-ml blood sample was taken for further serum zinc status using flame atomic absorption spectrophotometry technique. Pearson's r was used to show the correlation between quantitative variables. Both daily zinc intake and serum zinc concentrations of MDD group were about two thirds of healthy index (p Depressed individuals used to eat lower servings of red meats and chicken as the main food sources of zinc in students' usual diets (p students (r = 0.55; p students(r = -0.65; p depressed female students, dietary zinc intake is correlated to its serum concentrations; however, the serum zinc levels are inversely correlated to depression scales. Consumption of the main dietary sources of zinc such as red meats and chicken should be encouraged in young depressed girls.

  5. Multi-scale motility amplitude associated with suicidal thoughts in major depression.

    Directory of Open Access Journals (Sweden)

    Premananda Indic

    Full Text Available Major depression occurs at high prevalence in the general population, often starts in juvenile years, recurs over a lifetime, and is strongly associated with disability and suicide. Searches for biological markers in depression may have been hindered by assuming that depression is a unitary and relatively homogeneous disorder, mainly of mood, rather than addressing particular, clinically crucial features or diagnostic subtypes. Many studies have implicated quantitative alterations of motility rhythms in depressed human subjects. Since a candidate feature of great public-health significance is the unusually high risk of suicidal behavior in depressive disorders, we studied correlations between a measure (vulnerability index [VI] derived from multi-scale characteristics of daily-motility rhythms in depressed subjects (n = 36 monitored with noninvasive, wrist-worn, electronic actigraphs and their self-assessed level of suicidal thinking operationalized as a wish to die. Patient-subjects had a stable clinical diagnosis of bipolar-I, bipolar-II, or unipolar major depression (n = 12 of each type. VI was associated inversely with suicidal thinking (r = -0.61 with all subjects and r = -0.73 with bipolar disorder subjects; both p<0.0001 and distinguished patients with bipolar versus unipolar major depression with a sensitivity of 91.7% and a specificity of 79.2%. VI may be a useful biomarker of characteristic features of major depression, contribute to differentiating bipolar and unipolar depression, and help to detect risk of suicide. An objective biomarker of suicide-risk could be advantageous when patients are unwilling or unable to share suicidal thinking with clinicians.

    The purpose of this study was to use a meta-analytic method known as reliability generalization to investigate the score reliability for a popular depression measure: The Reynolds Adolescent Depression Scale. We used the technique to provide an aggregate estimate of coefficient alpha across empirical studies that have employed the measure over time and across populations. Furthermore, we identified sample and demographic characteristics associated with variance in coefficient alpha. We discuss conditions associated with variability in coefficient alpha and alert researchers and practitioners to appropriate uses of the scale based on common reliability benchmarks.

    Full Text Available Abstract Background The Hospital Anxiety and Depression Scale (HADS has been used in several languages to assess anxiety and depression in general hospital patients with good results. Methods The HADS was administered to 521 participants (275 controls and 246 inpatients and outpatients of the Internal Medicine and Surgical Departments in 'Attikon' General Hospital in Athens. The Beck Depression Inventory (BDI and the State-Trait Anxiety Inventory (STAI were used as 'gold standards' for depression and anxiety respectively. Results The HADS presented high internal consistency; Cronbach's α cofficient was 0.884 (0.829 for anxiety and 0.840 for depression and stability (test-retest intraclass correlation coefficient 0.944. Factor analysis showed a two-factor structure. The HADS showed high concurrent validity; the correlations of the scale and its subscales with the BDI and the STAI were high (0.722 – 0.749. Conclusion The Greek version of HADS showed good psychometric properties and could serve as a useful tool for clinicians to assess anxiety and depression in general hospital patients.

    The Depression Anxiety Stress Scale (DASS) was designed to efficiently measure the core symptoms of anxiety and depression and has demonstrated positive psychometric properties in adult samples of anxiety and depression patients and student samples. Despite these findings, the psychometric properties of the DASS remain untested in older adults, for whom the identification of efficient measures of these constructs is especially important. To determine the psychometric properties of the DASS 21-item version in older adults, we analyzed data from 222 medical patients seeking treatment to manage worry. Consistent with younger samples, a three-factor structure best fit the data. Results also indicated good internal consistency, excellent convergent validity, and good discriminative validity, especially for the Depression scale. Receiver operating curve analyses indicated that the DASS-21 predicted the diagnostic presence of generalized anxiety disorder and depression as well as other commonly used measures. These data suggest that the DASS may be used with older adults in lieu of multiple scales designed to measure similar constructs, thereby reducing participant burden and facilitating assessment in settings with limited assessment resources.

    The study was proposed to evaluate co-morbid depression, anxiety and stress associated with tinnitus patients. The study was done on 196 subjects: 100 patients suffering from subjective tinnitus associated with hearing loss (tinnitus group), 45 patients suffering from hearing loss only (hearing loss group) and 50 healthy subjects not suffering from tinnitus or hearing loss (control group); the age ranges from 20 to 60 years old. The studied sample was subjected to full ear, nose and throat examinations and audiological evaluation. Depression, Anxiety and Stress Scale (DASS) was developed by Levibond H and Levibond F to assess three self-report scales designed to measure the negative emotional status of depression, anxiety and stress. All patients and control group were evaluated by DASS. (1) Depression: males were affected more than females. All patients over 60 years were affected by depression. The duration of tinnitus seems correlating with the severity of depression. Only 2 patients (4.3 %) of the hearing loss group suffer from depression. (2) Anxiety: 90 % of males suffer from anxiety as compared to 83.3 % females. The age group 20-29 years old suffers more than other age groups. Only 4 patients (8.7 %) of hearing loss group suffer from anxiety. (3) Stress: females seem to be affected by the stress (76.7 %) more than males (67.5). Patients in age group 30-39 suffer the most from the disease. There is a direct correlation between duration of tinnitus and severity of stress. No one of the hearing loss group suffers from stress. In conclusion, depression, anxiety and stress should be taken into consideration in the treatment of patients suffering from tinnitus.

    Full Text Available Objectives: Optimal depression screening necessitates measurement tools that are valid across varied populations and in the presence of comorbidities. Methods: This study assessed the test properties of two versions of the Center for Epidemiologic Studies Depression scale against psychiatric diagnoses established by the Mini International Neuropsychiatric Interview among a clinical sample of US Veterans deployed during Operations Enduring Freedom, Iraqi Freedom, and New Dawn. Participants (N = 359 recruited from two Department of Veterans Affairs hospitals completed a clinical interview, structured diagnostic interview, and self-reported measures. Results: Based on diagnostic interview and the Diagnostic and Statistical Manual of Mental Disorders 4th Edition criteria, 29.5% of the sample met diagnostic criteria for major depressive disorder and 26.5% met diagnostic criteria for post-traumatic stress disorder.

    Traditionally, CE with SDS (CE-SDS) places many restrictions on sample composition. Requirements include low salt content, known initial sample concentration, and a narrow window of final sample concentration. As these restrictions require buffer exchange for many sample types, sample preparation is often tedious and yields poor sample recoveries. To improve capacity and streamline sample preparation, an automated robotic platform was developed using the PhyNexus Micro-Extractor Automated Instrument (MEA) for both the reduced and nonreduced CE-SDS assays. This automated sample preparation normalizes sample concentration, removes salts and other contaminants, and adds the required CE-SDS reagents, essentially eliminating manual steps during sample preparation. Fc-fusion proteins and monoclonal antibodies were used in this work to demonstrate benefits of this approach when compared to the manual method. With optimized conditions, this application has demonstrated decreased analyst "hands on" time and reduced total assay time. Sample recovery greater than 90% can be achieved, regardless of initial composition and concentration of analyte.

    2011-09-01

    Full Text Available Abstract Background The Hospital Anxiety and Depression Scale (HADS is commonly used to assess symptoms of anxiety and depression in motor neurone disease (MND. The measure has never been specifically validated for use within this population, despite questions raised about the scale's validity. This study seeks to analyse the construct validity of the HADS in MND by fitting its data to the Rasch model. Methods The scale was administered to 298 patients with MND. Scale assessment included model fit, differential item functioning (DIF, unidimensionality, local dependency and category threshold analysis. Results Rasch analyses were carried out on the HADS total score as well as depression and anxiety subscales (HADS-T, D and A respectively. After removing one item from both of the seven item scales, it was possible to produce modified HADS-A and HADS-D scales which fit the Rasch model. An 11-item higher-order HADS-T total scale was found to fit the Rasch model following the removal of one further item. Conclusion Our results suggest that a modified HADS-A and HADS-D are unidimensional, free of DIF and have good fit to the Rasch model in this population. As such they are suitable for use in MND clinics or research. The use of the modified HADS-T as a higher-order measure of psychological distress was supported by our data. Revised cut-off points are given for the modified HADS-A and HADS-D subscales.

    The main purpose of the present study was to assess the depressive symptomatology and to gather new validity evidences of the Reynolds Depression Scale-Short form (RADS-SF) in a representative sample of youths. The sample consisted of 2914 adolescents with a mean age of 15.85 years (SD = 1.68). We calculated the descriptive statistics and internal consistency of the RADS-SF scores. Also, confirmatory factor analyses (CFAs) at the item level and successive multigroup CFAs to test measurement invariance, were conducted. Latent mean differences across gender and educational level groups were estimated, and finally, we studied the sources of validity evidences with other external variables. The level of internal consistency of the RADS-SF Total score by means of Ordinal alpha was .89. Results from CFAs showed that the one-dimensional model displayed appropriate goodness of-fit indices with CFI value over .95, and RMSEA value under .08. In addition, the results support the strong measurement invariance of the RADS-SF scores across gender and age. When latent means were compared, statistically significant differences were found by gender and age. Females scored 0.347 over than males in Depression latent variable, whereas older adolescents scored 0.111 higher than the younger group. In addition, the RADS-SF score was associated with the RADS scores. The results suggest that the RADS-SF could be used as an efficient screening test to assess self-reported depressive symptoms in adolescents from the general population. PMID:28222193

    This study aimed to assess whether male and female Iranian medical students perceived the meaning of the items in the Depression Anxiety Stress Scales-21 consistently. A convenience sample of 783 preclinical medical students from the first to sixth semester was invited to this cross-sectional study. Of the 477 respondents, 238 were male and 239 were female. All participants completed the Persian version of the Depression Anxiety Stress Scales-21. The graded response model was used to assess measurement invariance of the instrument across the gender groups. Categorical confirmatory factor analysis was used to evaluate the construct validity of the measure. Moreover, internal consistency was assessed via Cronbach's Alpha. Statistically significant differential item functioning was flagged for just item 6 in the depression subscales (c(2)=6.5, df=1, p=0.011). However, removing or retaining the item 6 in the stress subscale did not change our findings significantly, when we compared stress scores across two genders. The results of categorical confirmatory factor analysis supported the fit of the three-factor model of Depression Anxiety Stress Scales-21. Moreover, Cronbach's alpha was greater than 0.7 in depression, anxiety and stress subscales. This study revealed that Depression Anxiety Stress Scales-21 is an invariant measure across male and female medical students. Hence, this reliable and valid instrument can be used for meaningful comparison of distress scores between medical student genders. Gender comparisons of medical students' psychological profiles provide a better insight into gender influences on the outcome of medical education and medical practice.

    We evaluated the effects of a selective serotonin reuptake inhibitor, paroxetine, on treating tinnitus.Tinnitus patients stratified for the presence of depression and anxiety were studied retrospectively. Fifty-six patients were observed for more than 6 months. They were initially treated with paroxetine only at a dose of 10 mg/day for 2-4 weeks; thereafter, the dose was increased to 20 mg/day. Tinnitus distress was evaluated with the Tinnitus Handicap Inventory (THI) and with visual analog scales (VASs) for tinnitus loudness and annoyance. Depression and anxiety were measured with the Self-Rating Depression Scale (SDS) and the trait section of the State-Trait Anxiety Inventory (STAI). The patients were grouped according to their SDS and STAI scores, and each variable was compared at baseline and the 6-month follow-up. Changes among these variables were also examined to determine whether reduced tinnitus distress was related to the improvement of depression or anxiety. Patients with both depression and anxiety showed better results (decrease in THI, VASs, SDS and STAI scores) than patients with anxiety alone, or patients without depression and anxiety. In patients with depression and anxiety, changes in tinnitus variables and changes in depression and anxiety scores were strongly correlated. In other patients, however, changes in tinnitus variables and changes in depression and anxiety scores were not correlated. These results suggest that paroxetine is effective in treating distressed tinnitus patients with depression and anxiety by reducing their tinnitus severity as well as their depression and anxiety.

    There is ample evidence that depression is000  a common comorbid health issue in people with type 1 or type 2 diabetes. Reviews have also concluded that depression in diabetes is associated with higher HbA1c levels, less optimal self-care behaviours, lower quality of life, incident vascular...... complications and higher mortality rates. However, longitudinal studies into the course of depression in people with type 1 diabetes remain scarce. In this issue of Diabetologia, Kampling and colleagues (doi: 10.1007/s00125-016-4123-0 ) report the 5 year trajectories of depression in adults with newly diagnosed...... type 1 diabetes (mean age, 28 years). Their baseline results showed that shortly after the diagnosis of type 1 diabetes a major depressive episode was diagnosed in approximately 6% of participants, while 8% suffered from an anxiety disorder. The longitudinal depression data showed that, in a 5 year...

    The ICD-10 Symptom Rating (ISR) 1 measures the severity of psychiatric disorders with 29 items on 5 subscales as comprehensively as possible. The following syndromes are measured: Depressive syndrome, anxiety syndrome, obsessive-compulsive syndrome, Somatoform syndrome, eating disorder syndrome as well as additional items that cover various mental syndromes, and an overall score. The study reports findings on the validity and sensitivity to change of the depression subscale (ISR-D). In a clinical sample of N=949 inpatients with depression spectrum disorders the convergent validity was determined by correlation with the Beck Depression Inventory (BDI) 3 and the subscale "depression" of the Symptom-Checklist-90-R (SCL-90-R) 4. The high correlation between the different instruments confirms the validity of the ISR-Depression Scale. The sensitivity to change of the ISR seems higher than that of the BDI and the SCL-90. Because of its economy and the good psychometric properties the ISR is recommended for use in clinical samples.

    The integration of research into clinical practice to conduct effectiveness studies faces multiple obstacles. One obstacle is the burden of completing research measures of outcome. A simple, reliable, and valid measure that could be rated at every visit, incorporated into a clinician's progress note, and reflect the DSM-IV definition of a major depressive episode (including partial and full remission from the episode) would enhance the ability to conduct effectiveness research. The goal of the present study was to examine the reliability and validity of such a measure. Three hundred and three psychiatric outpatients who were being treated for a DSM-IV major depressive episode were rated on the Standardized Clinical Outcome Rating for Depression (SCOR-D), 17-item Hamilton Rating Scale for Depression, Montgomery-Asberg Depression Rating Scale, and the Global Assessment of Functioning. We examined the correlation between the SCOR-D and the other measures, and conducted an analyses of variance to compare mean values on these measures for each rating point on the SCOR-D. The inter-rater reliability of the SCOR-D dimensional ratings and categorical determination of remission were high. The SCOR-D was highly correlated with the other scales, and there were significant differences on the other measures of depression severity between each adjacent rating level of the SCOR-D. The SCOR-D is a brief standardized outcome measure linked to the DSM-IV approach toward defining remission that can be incorporated into routine clinical practice without adding undue burden to the treating clinician with some evidence of reliability and validity. This measure could make it more feasible to conduct effectiveness studies in clinical practice.

    Full Text Available Abstract Background The Edinburgh Postnatal Depression Scale (EPDS is a 10 item self-rating post-natal depression scale which has seen widespread use in epidemiological and clinical studies. Concern has been raised over the validity of the EPDS as a single summed scale, with suggestions that it measures two separate aspects, one of depressive feelings, the other of anxiety. Methods As part of a larger cross-sectional study conducted in Melbourne, Australia, a community sample (324 women, ranging in age from 18 to 44 years: mean = 32 yrs, SD = 4.6, was obtained by inviting primiparous women to participate voluntarily in this study. Data from the EPDS were fitted to the Rasch measurement model and tested for appropriate category ordering, for item bias through Differential Item Functioning (DIF analysis, and for unidimensionality through tests of the assumption of local independence. Results Rasch analysis of the data from the ten item scale initially demonstrated a lack of fit to the model with a significant Item-Trait Interaction total chi-square (chi Square = 82.8, df = 40; p Conclusion The results of this study suggest that EPDS, in its original 10 item form, is not a viable scale for the unidimensional measurement of depression. Rasch analysis suggests that a revised eight item version (EPDS-8 would provide a more psychometrically robust scale. The revised cut points of 7/8 and 9/10 for the EPDS-8 show high levels of agreement with the original case identification for the EPDS-10.

    2011-08-01

    Full Text Available Abstract Background Depression is a common complication in type 2 diabetes (DM2, affecting 10-30% of patients. Since depression is underrecognized and undertreated, it is important that reliable and validated depression screening tools are available for use in patients with DM2. The Edinburgh Depression Scale (EDS is a widely used method for screening depression. However, there is still debate about the dimensionality of the test. Furthermore, the EDS was originally developed to screen for depression in postpartum women. Empirical evidence that the EDS has comparable measurement properties in both males and females suffering from diabetes is lacking however. Methods In a large sample (N = 1,656 of diabetes patients, we examined: (1 dimensionality; (2 gender-related item bias; and (3 the screening properties of the EDS using factor analysis and item response theory. Results We found evidence that the ten EDS items constitute a scale that is essentially one dimensional and has adequate measurement properties. Three items showed differential item functioning (DIF, two of them showed substantial DIF. However, at the scale level, DIF had no practical impact. Anhedonia (the inability to be able to laugh or enjoy and sleeping problems were the most informative indicators for being able to differentiate between the diagnostic groups of mild and severe depression. Conclusions The EDS constitutes a sound scale for measuring an attribute of general depression. Persons can be reliably measured using the sum score. Screening rules for mild and severe depression are applicable to both males and females.

    Full Text Available Abstract Background Edinburgh Postnatal Depression Scale (EPDS is an important screening instrument that is used routinely with mothers during the postpartum period for early identification of postnatal depression. The purpose of this study was to validate the Greek version of EPDS along with sensitivity, specificity and predictive values. Methods 120 mothers within 12 weeks postpartum were recruited from the perinatal care registers of the Maternity Departments of 4 Hospitals of Heraklion municipality, Greece. EPDS and Beck Depression Inventory-II (BDI-II surveys were administered in random order to the mothers. Each mother was diagnosed with depression according to the validated Greek version of BDI-II. The psychometric measurements that were performed included: two independent samples t-tests, One-way analysis of variance (ANOVA, reliability coefficients, Explanatory factor analysis using a Varimax rotation and Principal Components Method. Confirmatory analysis -known as structural equation modelling- of principal components was conducted by LISREL (Linear Structural Relations. A receiver operating characteristic (ROC analysis was carried out to evaluate the global functioning of the scale. Results 8 (6.7% of the mothers were diagnosed with major postnatal depression, 14 (11.7% with moderate and 38 (31.7% with mild depression on the basis of BDI-II scores. The internal consistency of the EPDS Greek version -using Chronbach's alpha coefficient- was found 0.804 and that of Guttman split-half coefficient 0.742. Our findings confirm the multidimensionality of EPDS, demonstrating a two-factor structure which contained subscales reflecting depressive symptoms and anxiety. The Confirmatory Factor analysis demonstrated that the two factor model offered a very good fit to our data. The area under ROC curve AUC was found 0.7470 and the logistic estimate for the threshold score of 8/9 fitted the model sensitivity at 76.7% and model specificity at 68

    The Hospital Anxiety and Depression Scale (HADS) is widely used as a tool for assessing psychological distress in patients and non-clinical groups. Previous studies have demonstrated conflicting results regarding the factor structure of the questionnaire for different groups of patients, and the general population. This study investigated the factor structure of the HADS in a large heterogeneous cancer population of 1474 patients. It also sought to investigate emerging evidence that the HADS conforms to the tripartite model of anxiety and depression (Clark & Watson, 1993), and to test the proposal that detection rates for clinical cases of anxiety and depression could be enhanced by partialling out the effects of higher order factors from the HADS (Dunbar et al., 2000). The results demonstrated a two-factor structure corresponding to the Anxiety and Depression subscales of the questionnaire. The factor structure remained stable for different subgroups of the sample, for males and females, as well as for different age groups, and a subgroup of metastatic cancer patients. The two factors were highly correlated (r =.52) and subsequent secondary factor analyses demonstrated a single higher order factor corresponding to psychological distress or negative affectivity. We concluded that the HADS comprises two factors corresponding to anhedonia and autonomic anxiety, which share a common variance with a primary factor namely psychological distress, and that the subscales of the HADS, rather than the residual scores (e.g. Dunbar et al., 2000) were more effective at detecting clinical cases of anxiety and depression.

    Postpartum depression incurs significant burden and suffering. We investigated the latent structure of the most commonly used screening measure, the Edinburgh Postnatal Depression Scale (EPDS) in women (N=15,172) and tested its predictive validity for the diagnosis of depression as determined with a structured clinical interview. Exploratory and confirmatory factor analyses, Receiver Operating Characteristic curves, and logistic regression analyses were conducted. A seven-item one factor scale (items 1, 2, 6, 7, 8, 9, 10) emerged with a Goodness of Index Fit Index (GFI) =.96, relative to the ten-item two factor version of the EPDS (GFI =.94). The seven-item EPDS achieved good sensitivity and specificity in predicting the 10-item EPDS, with a cut point score of 4 on the seven item EPDS to predict a 10-item EPDS score of 10 or more (sensitivity =95%, specificity =91%). The seven and 10-item EPDS showed a similar ability to predict a diagnoses of depression (area under the ROC curve=.795 for the 10-item, .770 for the seven-item EPDS). Logistic regression analyses showed similar predictive ability between the seven- and 10-item scales in predicting scores higher than 18 on the clinical interview LIMITATIONS: The sample represents women from one Midwest medical center and the EPDS was measured via phone. The seven-item one factor version of the EPDS is an efficient and effective measure of depression severity on par with the two factor 10-item version of the EPDS. Copyright © 2016 Elsevier B.V.

    Depression is one of the most prevalent mental disorders in later life. However, despite considerable research attention, great confusion remains regarding the association between ageing and depression. There is doubt as to whether a depression scale performs identically for different age groups and countries. Although measurement equivalence is a crucial prerequisite for valid comparisons across age groups and countries, it has not been established for the eight-item version of the Centre for Epidemiological Studies Depression Scale (CES-D8). Using multi-group confirmatory factor analysis, we assess configural, metric, and scalar measurement equivalence across two age groups (50-64 years of age and 65 or older) in eleven European countries, employing data from the Survey of Health, Ageing, and Retirement (SHARE). Results indicate that the construct of depression is comparable across age and country groups, allowing the substantive interpretation of correlates and mean levels of depressive symptoms.

    Growing cross-cultural awareness has led researchers to examine frequently used research instruments and assessment tools in racially diverse populations. The present study was conducted to assess the psychometric characteristics of the 21-item version of the Depression, Anxiety, and Stress Scales (DASS-21) among different racial groups. The DASS-21 was chosen because it appears to be a reliable and easy to administer measure, ideal for both clinical and research purposes. Results suggest that the internal consistency, and convergent and divergent validity of the DASS-21 are similar across racial groups. Multigroup CFA, however, indicated that item loadings were invariant, while scale covariances were not invariant. This suggests that, although the items may load similarly on the depression, anxiety and stress constructs, these constructs may be differentially inter-related across groups. Implications for application in clinical practice are discussed.

This study proposes to improve the reliability of the Clinical Global Impression (CGI scale in depressive disorders by the use of a semi-standardized interview, a new response format, and a Delphi procedure. Methods Thirty patients hospitalised for a major depressive episode were filmed at T1 (first week in hospital and at T2 (2 weeks later during a 5' specific interview. The Hamilton Depressive Rating Scale and the Symptom Check List were also rated. Eleven psychiatrists rated these videos using either the usual CGI response format or an improved response format, with or without a Delphi procedure. Results The new response format slightly improved (but not significantly the interrater agreement, the Delphi procedure did not. The best results were obtained when ratings by 4 independent raters were averaged. In this situation, intraclass correlation coefficients were about 0.9. Conclusion The Clinical Global Impression is a useful approach in psychiatry since it apprehends patients in their entirety. This study shows that it is possible to quantify such impressions with a high level of interrater agreement.

    Full Text Available Background/Aims: In Alzheimer disease (AD, depression is among the most common accompanying neuropsychiatric symptoms and has different clinical manifestations when compared with early-life depression. In patients with drug-naïve AD, we tried to explore the structure of the 15-item Geriatric Depression Scale (GDS15 and the effect of donepezil on these substructures. Methods: GDS15, cognitive function, and activities of daily living function tests were administered to 412 patients with probable AD who had not been medicated before visiting the hospital. Using principal component analysis, three factors were identified. The patients with AD who received only donepezil were retrospectively analyzed and we compared the change of cognition and GDS15 subgroup after donepezil medication. Results: Our study identified three factors and revealed that the GDS15 may be comprised of a heterogeneous scale. The Barthel index was significantly correlated with factor 1 (positively and factor 2 (negatively. The Korean version of the MMSE (K-MMSE was significantly correlated with factor 2 and factor 3. Compared to the baseline state, K-MMSE and GDS15 showed significant improvement after taking donepezil. Among GDS15 subgroups, factor 2 and factor 3 showed significant improvement after donepezil treatment. Conclusions: These results suggest that the GDS15 may be comprised of a heterogeneous scale and donepezil differentially affects the GDS15 subgroup in AD.

    Abstract: Our objectivewas to validate the different versions of the Hamilton Depression Scale (HAM-D) both psychometrically (scalability) and clinically in discriminating antidepressants from placebo in terms of remission rates in an 8-week clinical trial in the acute treatment of major depression...... in the longer HAM-D versions indicated smaller discriminating validity over placebo. The HAM-D6 indicated a dose effect on remission for vortioxetine in both moderate and severe major depression. The brief HAM-D6 was thus found superior to HAM-D17, HAM-D21, and HAM-D24 both in terms of scalability...

    The Center for Epidemiological Studies Depression Scale (CES-D) is an instrument that is commonly used to screen for depression in patients with chronic disease, but the characteristics of the CES-D in adults with congenital heart disease (CHD) have not yet been studied. The aim of this study was to investigate the criterion validities and the predictive powers of the CES-D for depression and anxiety disorders in adults with CHD. Two hundred patients were screened with the CES-D and secondarily interviewed with a diagnostic instrument, i.e., the Mini International Neuropsychiatric Instrument. The sensitivity and specificity values of the CES-D were calculated by cross-tabulation at different cutoff scores. Receiver operating characteristic (ROC) curves were used to assess the optimal cutoff point for each disorder and to assess the predictive power of the instrument. The CES-D exhibited satisfactory criterion validities for depression and for all combinations of depression and/or anxiety. With a desired sensitivity of at least 80%, the optimal cutoff scores were 18. The predictive power of the CES-D in the patients was best for major depression and dysthymia (area under the ROC curve: 0.92) followed by the score for any combination of depression and/or anxiety (0.88). The use of CES-D to simultaneously screen for both depression and anxiety disorders may be useful in adults with CHD. CESDEP 212. Registered 2 March 2014 (retrospectively registered).

    Although major depressive disorder (MDD) has a variety of symptoms beyond the affective dimensions, the factor structure and contents of comprehensive psychiatric symptoms of this disorder have rarely been explored using the 18-item Brief Psychiatric Rating Scale (BPRS). We aimed to identify the factor structure of the 18-item BPRS in Korean MDD patients. A total of 258 MDD patients were recruited from a multicenter sample of the Clinical Research Center for Depression of South Korea study. Psychometric scales were used to assess overall psychiatric symptoms (BPRS), depression (Hamilton Depression Rating Scale), anxiety (Hamilton Anxiety Rating Scale), global severity (Clinical Global Impression of Severity Scale), suicidal ideation (Scale for Suicide Ideation), functioning (Social and Occupational Functioning Assessment Scale), and quality of life (World Health Organization Quality of Life Assessment-abbreviated version). Common factor analysis with oblique rotation was used to yield factor structure. A four-factor structure was designed and interpreted by the symptom dimensions to reflect mood disturbance, positive symptoms/apathy, bipolarity, and thought distortion/mannerism. These individual factors were also significantly correlated with clinical variables. The findings of this study support the view that the BPRS may be a promising measuring tool for the initial assessment of MDD patients. In addition, the four-factor structure of the BPRS may be useful in understanding the mood and psychotic characteristics of these patients.

    Depression is a common occurrence in patients with Parkinson's disease (PD). Pramipexole is a dopamine agonist that has been used to treat both motor and non-motor symptoms associated with PD. We conducted a study to elucidate the effect of pramipexole on each of the depressive symptoms as assessed by the Zung Self-Rating Depression Scale (SDS). Twenty patients with PD were treated with pramipexole 1.5-3.0 mg daily for 2-3 months. The SDS and the Unified Parkinson Disease Rating Score (UPDRS) were measured in each subject before and after the treatment. Both the SDS and the UPDRS decreased significantly after treatment with pramipexole. Individual assessment of each item in the SDS indicated that "crying spell", "confusion", "psychomotor retardation", "emptiness", and "dissatisfaction" symptoms improved significantly following treatment, while "depressed affect", "decreased libido", "constipation", and "indecisiveness" symptoms were worse after the treatment. As the symptom of "indecisiveness" did not respond to treatment, it might be an essential symptom in patients with PD.

    Objective Karoshi, which is the Japanese term for death from over-work, is usually the extreme result of cardiovascular diseases, and occupational stress plays a pivotal role in the pathogenesis. Depression is closely associated with atherosclerotic cardiovascular disease. The present study was undertaken to examine the relationship between occupational stress and depression. Methods We enrolled 231 consecutive outpatients with lifestyle-related diseases such as diabetes, hyperlipidemia and hypertension were enrolled. Occupational stress was measured by qualitative constructs assessing job control, job demands, and worksite social support using a job content questionnaire (JCQ). The job strain index measured by the ratio of job demands to job control was used as an indicator of the occupational stress. Depression was evaluated by the Self-rating Depression Scale (SDS). Results A univariate linear regression analysis showed the SDS scores to be positively correlated with job demands and the job strain index and negatively correlated with job control and worksite social support. Multiple regression analyses to predict the SDS scores demonstrated that job demands were positively associated with SDS scores and job control and worksite social support were negatively associated with SDS scores after controlling for other variables. The job strain index was positively related to SDS scores. Conclusion Occupational stress expressed as the job strain index was strongly associated with depression. By simultaneously using the SDS and JCQ, the health conditions of patients could be classified based on occupational stress and mental stress, and this classification could help to promote a healthy work environment and guide individual workers.

  5. Performance of the Visual Analogue Scale of Happiness and of the Cornell Scale for Depression in Dementia in the Tremembé Epidemiological Study, Brazil

    Full Text Available Depression is a major growing public health problem. Many population studies have found a significant relationship between depression and the presence of cognitive disorders. OBJECTIVE: To establish the correlation between the Visual Analogue Scale of Happiness and the Cornell Scale for Depression in Dementia in the population aged 60 years or over in the city of Tremembé, state of São Paulo, Brazil. METHODS: An epidemiological survey involving home visits was carried out in the city of Tremembé. The sample was randomly selected by drawing 20% of the population aged 60 years or older from each of the city's census sectors. In this single-phase study, the assessment included clinical history, physical and neurological examination, cognitive evaluation, and application of both the Cornell Scale and the Analogue Scale of Happiness for psychiatric symptoms. The presence of depressive symptoms was defined as scores greater than or equal to 8 points on the Cornell Scale. RESULTS: A total of 623 subjects were evaluated and of these 251 (40.3% had clinically significant depressive symptoms on the Cornell Scale, with a significant association with female gender (p<0.001 and with lower education (p=0.012. One hundred and thirty-six participants (21.8% chose the unhappiness faces, with a significant association with age (p<0.001, female gender (p=0.020 and low socioeconomic status (p=0.012. Although there was a statistically significant association on the correlation test, the correlation was not high (rho=0.47. CONCLUSION: The prevalence of depressive symptoms was high in this sample and the Visual Analogue Scale of Happiness and Cornell Scale for Depression in Dementia should not be used as similar alternatives for evaluating the presence of depressive symptoms, at least in populations with low educational level.

    Anxiety and depression are among the most common mental disorders during childhood and adolescence. Among the instruments for the brief screening assessment of symptoms of anxiety and depression, the Revised Child Anxiety and Depression Scale (RCADS) is one of the more widely used. Previous studies have demonstrated the reliability of the RCADS for different assessment settings and different versions. The aims of this study were to examine the mean reliability of the RCADS and the influence of the moderators on the RCADS reliability. We searched in EBSCO, PsycINFO, Google Scholar, Web of Science, and NCBI databases and other articles manually from lists of references of extracted articles. A total of 146 studies were included in our meta-analysis. The RCADS showed robust internal consistency reliability in different assessment settings, countries, and languages. We only found that reliability of the RCADS was significantly moderated by the version of RCADS. However, these differences in reliability between different versions of the RCADS were slight and can be due to the number of items. We did not examine factor structure, factorial invariance across gender, age, or country, and test-retest reliability of the RCADS. The RCADS is a reliable instrument for cross-cultural use, with the advantage of providing more information with a low number of items in the assessment of both anxiety and depression symptoms in children and adolescents.

    Full Text Available BACKGROUND: The Edinburgh Postnatal Depression Scale (EPDS is a widely used screening tool for postpartum depression (PPD. Although the reliability and validity of EPDS in Japanese has been confirmed and the prevalence of PPD is found to be about the same as Western countries, the factor structure of the Japanese version of EPDS has not been elucidated yet. METHODS: 690 Japanese mothers completed all items of the EPDS at 1 month postpartum. We divided them randomly into two sample sets. The first sample set (n = 345 was used for exploratory factor analysis, and the second sample set was used (n = 345 for confirmatory factor analysis. RESULTS: The result of exploratory factor analysis indicated a three-factor model consisting of anxiety, depression and anhedonia. The results of confirmatory factor analysis suggested that the anxiety and anhedonia factors existed for EPDS in a sample of Japanese women at 1 month postpartum. The depression factor varies by the models of acceptable fit. CONCLUSIONS: We examined EPDS scores. As a result, "anxiety" and "anhedonia" exist for EPDS among postpartum women in Japan as already reported in Western countries. Cross-cultural research is needed for future research.

    The negative symptoms of schizophrenia have generated a great interest leading some authors (Crow, Andreasen, Kay) to delineate schizophrenic subtypes based on their presence or absence. Carpenter et al. have recently proposed another subtype, the deficit syndrome, based on Kraepelin's clinical description. This differs from other proposed negative subtypes and refers to the presence or absence of prominent, enduring and primary negative symptoms. Primary negative symptoms have to be due to psychophrenia itself, in other words, independent of factors such as depression, anxiety, akinesia... Kirkpatrick et al. have proposed the Schedule for the Deficit Syndrome (SDS) to reliably identify this deficit syndrome. Some studies using this instrument have supported the validity of the deficit syndrome concept. Particularly, deficit patients have clinical, neuropsychological, neurological, eye-tracking and brain imaging impairments compared to nondeficit patients. We realized a french translation of SDS and used it to study a biological index (plasma homovanillic acid, pHVA) among deficit and nondeficit schizophrenic patients. Our data suggest a specific biochemical basis for the deficit syndrome, ie, significant lower mean pHVA levels with a lack of diurnal variation for deficit patients. The french version of SDS was validated by Kirkpatrick after english back translation. We present here our psychometric data regarding reliability (assessed by weighted and unweighted kappa coefficients) and cohesiveness of the construct (assessed by rank-order correlations of each negative symptoms with the other five, using Spearman's rho). These data are quite significant and in agreement with the SDS authors.

    In the efficacy evaluation of antidepressant treatments, the total score of the Hamilton Depression Rating Scale (HAMD) is still regarded as the 'gold standard'. We previously had shown that the Inventory of Depressive Symptomatology (IDS) was more sensitive to detect depressive symptom changes than the HAMD17 (Helmreich et al. 2011). Furthermore, studies suggest that the unidimensional subscales of the HAMD, which capture the core depressive symptoms, outperform the full HAMD regarding the detection of antidepressant treatment effects. The aim of the present study was to compare several unidimensional subscales of the HAMD and the IDS regarding their sensitivity to changes in depression symptoms in a sample of patients with mild major, minor or subsyndromal depression (MIND). Biweekly IDS-C28 and HAMD17 data from 287 patients of a 10-week randomised, placebo-controlled trial comparing the effectiveness of sertraline and cognitive-behavioural group therapy in patients with MIND were converted to subscale scores and analysed during the antidepressant treatment course. We investigated sensitivity to depressive change for all scales from assessment-to-assessment, in relation to depression severity level and placebo-verum differences. The subscales performed similarly during the treatment course, with slight advantages for some subscales in detecting treatment effects depending on the treatment modality and on the items included. Most changes in depressive symptomatology were detected by the IDS short scale, but regarding the effect sizes, it performed worse than most subscales. Unidimensional subscales are a time- and cost-saving option in judging drug therapy outcomes, especially in antidepressant treatment efficacy studies. However, subscales do not cover all facets of depression (e.g. atypical symptoms, sleep disturbances), which might be important for comprehensively understanding the nature of the disease depression. Therefore, the cost-to-benefit ratio must be

    The aim of the study was to compare criterion validities of the WHO-Five Well-being Index (WHO-5) and the Geriatric Depression Scale 15-item version (GDS-15) and 4-item version (GDS-4) as screening instruments for depression in nursing home residents. Data from 92 residents aged 65-97 years without severe cognitive impairment (Mini Mental State Examination ≥15) were analysed. Criterion validities of the WHO-5, the GDS-15 and the GDS-4 were assessed against diagnoses of major and minor depression provided by the Structured Clinical Interview for DSM-IV. Subanalyses were performed for major and minor depression. Areas under the receiver operating curve (AUCs) as well as sensitivities and specificities at optimal cut-off points were computed. Prevalence of depressive disorder was 28.3%. The AUC value of the WHO-5 (0.90) was similar to that of the GDS-15 (0.82). Sensitivity of the WHO-5 (0.92) at its optimal cut-off of ≤12 was significantly higher than that of the GDS-15 (0.69) at its optimal cut-off of ≥7. The WHO-5 was equally sensitive for the subgroups of major and minor depression (0.92), whereas the GDS-15 was sensitive only for major depression (0.85), but not for minor depression (0.54). For specificity, there was no significant difference between WHO-5 (0.79) and GDS-15 (0.88), but both instruments outperformed the GDS-4 (0.53). The WHO-5 demonstrated high sensitivity for major and minor depression. Being shorter than the GDS-15 and superior to the GDS-4, the WHO-5 is a promising screening tool that could help physicians improve low recognition rates of depression in nursing home residents.

    Depression is a common condition in primary care medicine in all population groups. We wanted to validate an Arabic translation Zung Self-Rating Depression Scale for Arabic speakers as it has been validated in a number of other languages. The hospital translation service translated the English version into Arabic, which was verified by back translation. This version was tested in a pilot study with 40 bilingual Arabic-English clinicians and Arabic linguistic experts. Revised questions were subjected to another translation-back translation and the final version tested in a clinical trial with 240 consenting bilingual English-Arabic speakers. The subjects were randomly assigned to answer either the English or Arabic version of the Zung questionnaire first, ensuring that subjects had no access to previous answers when answering the questionnaire in the other language. The scores obtained were tested for agreement using the kappa statistic. We found substantial agreement between the scores obtained from the two questionnaires. The kappa measurement of agreement was 0.652 (95% confidence interval, 0.571-0.732) We believe the Arabic translation of the English Zung Self-Rating Depression Scale is valid and reliable, and will be useful to practitioners who would like to use this tool in Arabic-speaking patients.

    Full Text Available Regarding the standardization of psychological instruments, that is, the construction of referential interpretations of a test, we can find different procedures performed both by Classical Test Theory and the Theory of Item Response. Especially in this case (IRT, we can admit a test as a norm, in order to use its standardization and transfer the cut-off point to another instrument. Based on this information, the present study aimed to provide a cutoff score for the Baptista Depression Scale - Adult Version (EBADEP-A through procedures of norms-transfer based on the Center for Epidemiologic Studies – Depression Scale (CES-D. The EBADEP-A presented good distribution and ability to discriminate depressive symptoms, and the sample, consisting of Brazilian College students, received a cutoff score of 32 points. It is emphasized that this is an exploratory and preliminary study, and it we suggest further analyzes to be performed with clinical samples for which results can be corroborated or confronted.

    The gap between the demand and delivery of mental health services in mainland China can be reduced by validating freely available and psychometrically sound psychological instruments. The present research examined the Chinese version of the 21-item Depression Anxiety Stress Scales (DASS-21). Study 1 administered the DASS-21 to 1,815 Chinese college students and found internal consistency indices (Cronbach's alpha) of .83, .80, and .82 for the Depression, Anxiety, and Stress subscales, respectively, and .92 for the total DASS total. Test-retest reliability over a 6-month interval was .39 to .46 for each of the 3 subscales and .46 for the total DASS. Moderate convergent validity of the Depression and Anxiety subscales was demonstrated via significant correlations with the Chinese Beck Depression Inventory (r = .51 at Time 1 and r = .64 at Time 2) and the Chinese State-Trait Anxiety Inventory (r = .41), respectively. Confirmatory factor analyses supported the original 3-factor model with 1 minor change (nonnormed fit index [NNFI] = .964, comparative fit index [CFI] = .968, and root mean square error of approximation [RMSEA] = .079). Study 2 examined the clinical utility of the Chinese DASS-21 in 166 patients with schizophrenia and 90 matched healthy controls. Patients had higher Depression and Anxiety but not Stress subscale scores than healthy controls. A discriminant function composed of the linear combination of 3 subscale scores correctly discriminated 69.92% of participants, which again supported the potential clinical utility of the DASS in mainland China. Taken together, findings in these studies support the cross-cultural validity of the DASS-21 in China. (PsycINFO Database Record

    Background Universal screening for postpartum depression is recommended in many countries. Knowledge of whether the disclosure of depressive symptoms in the postpartum period differs across cultures could improve detection and provide new insights into the pathogenesis. Moreover, it is a necessary step to evaluate the universal use of screening instruments in research and clinical practice. In the current study we sought to assess whether the Edinburgh Postnatal Depression Scale (EPDS), the most widely used screening tool for postpartum depression, measures the same underlying construct across cultural groups in a large international dataset. Method Ordinal regression and measurement invariance were used to explore the association between culture, operationalized as education, ethnicity/race and continent, and endorsement of depressive symptoms using the EPDS on 8209 new mothers from Europe and the USA. Results Education, but not ethnicity/race, influenced the reporting of postpartum depression [difference between robust comparative fit indexes (Δ*CFI) 0.01), but not between European countries (Δ*CFI depression that women of different educational backgrounds may manifest. The increasing cultural heterogeneity of societies together with the tendency towards globalization requires a culturally sensitive approach to patients, research and policies, that takes into account, beyond rhetoric, the context of a person’s experiences and the context in which the research is conducted.

    We sought to evaluate the capacity of the Edinburgh Postnatal Depression Scale (EPDS) in discriminating mental disorders other than depression in pregnant women in northern Mexico. Three hundred pregnant women attending prenatal consultations in a public hospital in Durango City, Mexico submitted a validated EPDS and were examined for mental disorders other than depression using the Diagnostic and Statistical Manual of Mental Disorders - 4(th) Ed. (DSM-IV) criteria. Sensitivity and specificity of cut-off points of the EPDS, and positive and negative predictive values were calculated. Of the 300 pregnant women studied, 21 had mental disorders other than depression by the DSM-IV criteria. The best EPDS score for screening mental disorders other than depression was 8/9. This threshold showed a sensitivity of 52.4%, a specificity of 67.0%, a positive predictive value of 11.5%, a negative predictive value of 95.4%, and an area under the curve of 0.643 (95% confidence interval: 0.52-0.76). The EPDS can be considered for screening mental disorders other than depression in Mexican pregnant women whenever a cut-off score of 8/9 is used. However, the tool showed small power to separate pregnant women with and without mental disorders other than depression.

    Full Text Available OBJECTIVE: This study aimed to develop a culturally acceptable and valid scale to assess depressive symptoms in older Indigenous Australians, to determine the prevalence of depressive disorders in the older Kimberley community, and to investigate the sociodemographic, lifestyle and clinical factors associated with depression in this population. METHODS: Cross-sectional survey of adults aged 45 years or over from six remote Indigenous communities in the Kimberley and 30% of those living in Derby, Western Australia. The 11 linguistic and culturally sensitive items of the Kimberley Indigenous Cognitive Assessment of Depression (KICA-dep scale were derived from the signs and symptoms required to establish the diagnosis of a depressive episode according to the DSM-IV-TR and ICD-10 criteria, and their frequency was rated on a 4-point scale ranging from 'never' to 'all the time' (range of scores: 0 to 33. The diagnosis of depressive disorder was established after a face-to-face assessment with a consultant psychiatrist. Other measures included sociodemographic and lifestyle factors, and clinical history. RESULTS: The study included 250 participants aged 46 to 89 years (mean±SD = 60.9±10.7, of whom 143 (57.2% were women. The internal reliability of the KICA-dep was 0.88 and the cut-point 7/8 (non-case/case was associated with 78% sensitivity and 82% specificity for the diagnosis of a depressive disorder. The point-prevalence of a depressive disorder in this population was 7.7%; 4.0% for men and 10.4% for women. Heart problems were associated with increased odds of depression (odds ratio = 3.3, 95% confidence interval = 1.2,8.8. CONCLUSIONS: The KICA-dep has robust psychometric properties and can be used with confidence as a screening tool for depression among older Indigenous Australians. Depressive disorders are common in this population, possibly because of increased stressors and health morbidities.

    Major depressive disorder (MDD) often emerges during adolescence, a critical period of brain development. Recent resting-state fMRI studies of adults suggest that MDD is associated with abnormalities within and between resting-state networks (RSNs). Here we tested whether adolescent MDD is characterized by abnormalities in interactions among RSNs. Participants were 55 unmedicated adolescents diagnosed with MDD and 56 matched healthy controls. Functional connectivity was mapped using resting-state fMRI. We used the network-based statistic (NBS) to compare large-scale connectivity between groups and also compared the groups on graph metrics. We further assessed whether group differences identified using nodes defined from functionally defined RSNs were also evident when using anatomically defined nodes. In addition, we examined relations between network abnormalities and depression severity and duration. Finally, we compared intranetwork connectivity between groups and assessed the replication of previously reported MDD-related abnormalities in connectivity. The NBS indicated that, compared with controls, depressed adolescents exhibited reduced connectivity (pdepression was significantly correlated with reduced connectivity in this set of network interactions (p=0.020, corrected), specifically with reduced connectivity between components of the dorsal attention network. The dorsal attention network was also characterized by reduced intranetwork connectivity in the MDD group. Finally, we replicated previously reported abnormal connectivity in individuals with MDD. In summary, adolescents with MDD show hypoconnectivity between large-scale brain networks compared with healthy controls. Given that connectivity among these networks typically increases during adolescent neurodevelopment, these results suggest that adolescent depression is associated with abnormalities in neural systems that are still developing during this critical period.

    Full Text Available ABSTRACT BACKGROUND: Fatigue is a common complaint in cirrhotic patients and may be considered a debilitating symptom with negative impact on quality of life. Research on its etiology and treatment has been hampered by the lack of relevant and reproducible measures of fatigue. OBJECTIVE: To evaluate the psychometric properties of the Fatigue Severity Scale (FSS in cirrhotic patients and to correlate with depressive symptomatology and quality of life. METHODS: Cross-sectional study with a convenience sample of 106 cirrhotic patients, aged between 18 and 70 years, both genders, literate, pre and post liver transplantation in outpatient follow-up. Internal consistency, reproducibility, discriminant validity, criterion validity, construct validity, responsiveness criterion, depressive symptomatology and quality of life were evaluated through questionnaires between January and October 2015. RESULTS: The mean age was 54.75±9.9 years, 65.1% male and 32.1% of the sample had cirrhosis due to hepatitis C virus. The mean FSS score was 4.74±1.64. Cronbach’s alpha was 0.93, and the Intraclass Correlation Coefficient was 0.905 (95% CI: 0.813-0.952. For discriminant validity, FSS differentiated scores from different groups (P=0.009 and presented a correlation with the Modified Fatigue Impact Scale (r=0.606, P=0.002. FSS correlated significantly and positively with depressive symptomatology and correlated negatively with the SF-36 domains for construct validity. For responsiveness, no significant changes were observed in the fatigue scores in the pre and post-liver transplantation periods (P=0.327. CONCLUSION: FSS showed good psychometric performance in the evaluation of fatigue in patients with cirrhosis. Fatigue presented a strong correlation with depressive symptomatology and quality of life.

    Previous research has investigated the manner in which absolute height impacts on jealousy and mate retention. Although relative height is also important, little information exists about the potential influence of sexual dimorphism in stature (SDS) within established relationships. The current study investigated the relationship between SDS and the satisfaction, jealousy and mate retention behaviors reported by men and women. Heterosexual men (n = 98) and women (n = 102) completed a questionnaire. Men in high SDS relationships reported the lowest levels of cognitive and behavioral jealousy, although the impact of SDS on relationship satisfaction was less clear. SDS was not associated with the overall use of mate retention strategies; SDS did however affect the use of three specific strategies (vigilance, monopolization of time, love and care). SDS did not affect women's relationship satisfaction, jealousy (cognitive, behavioral, or emotional) or the use of mate retention strategies (with the exception of resource display).

    The Cognitive and Behavioral Response to Stress Scale (CB-RSS) is a self-report measure of the use and helpfulness of several cognitive and behavioral skills. Unlike other measures that focus on language specific to terms used in therapy, the CB-RSS was intended to tap the strategies in ways that might be understandable to those who had not undergone therapy. The measure was included in a clinical trial of cognitive-behavioral therapy for depression and completed by 325 participants at baseline and end of treatment (18 weeks). Psychometric properties of the scale were assessed through iterative exploratory and confirmatory factor analyses. These analyses identified two subscales, cognitive and behavioral skills, each with high reliability. Validity was addressed by investigating relationships with depression symptoms, positive affect, perceived stress, and coping self-efficacy. End of treatment scores predicted changes in all outcomes, with the largest relationships between baseline CB-RSS scales and coping self-efficacy. These findings suggest that the CB-RSS is a useful tool to measure cognitive and behavioral skills both at baseline (prior to treatment) as well as during the course of treatment.

    Full Text Available Background: Self-stigma may feature strongly and be detrimental for people with depression, but the understanding of its nature and prevalence is limited by the lack of psychometrically validated measures. This study is aimed to validate the Arabic version self-stigma of depression scale (SSDS among adolescents. Materials and Methods: A cross-sectional study involved 100 adolescents randomly selected. The analyses include face validation, factor analysis, and reliability testing. A test–retest was conducted within a 2-week interval. Results: The mean score for self-stigma of depression among study participants was 68.9 (Standard deviation = 8.76 median equal to 71 and range was 47. Descriptive analysis showed that the percentage of those who scored below the mean score (41.7% is shown less than those who scored above the mean score (58.3%. Preliminary construct validation analysis confirmed that factor analysis was appropriate for the Arabic-translated version of the SSDS. Furthermore, the factor analysis showed similar factor loadings to the original English version. The total internal consistency of the translated version, which was measured by Cronbach's alphas ranged from 0.70 to 0.77 for the four subscales and 0.84 for the total scale. Test–retest reliability was assessed in 65 respondents after 2 weeks. Cronbach's alphas ranged from 0.70 to 0.77 for the four subscales and 0.84 for the total scale. Conclusions: Face validity, construct validity, and reliability analysis were found satisfactory for the Arabic-translated version of the SSDS. The Arabic-translated version of the SSDS was found valid and reliable to be used in future studies, with comparable properties to the original version and to previous studies.

    Full Text Available Abstract Background The study aimed at presenting normative data for both parallel forms of the "Rasch-based Depression Screening (DESC", to examine its Rasch model conformity and convergent and divergent validity based on a representative sample of the German general population. Methods The sample was selected with the assistance of a demographic consulting company applying a face to face interview (N = 2509; mean age = 49.4, SD = 18.2; 55.8% women. Adherence to Rasch model assumptions was determined with analysis of Rasch model fit (infit and outfit, unidimensionality, local independence (principal component factor analysis of the residuals, PCFAR and differential item functioning (DIF with regard to participants' age and gender. Norm values were calculated. Convergent and divergent validity was determined through intercorrelations with the depression and anxiety subscales of the Hospital Anxiety and Depression Scale (HADS-D and HADS-A. Results Fit statistics were below critical values (rDESC-I = .61 and rDESC-II = .60, whereas correlations with HADS-A were rDESC-I = .62 and rDESC-II = .60. Conclusions This study provided further support for the psychometric quality of the DESC. Both forms of the DESC adhered to Rasch model assumptions and showed intercorrelations with HADS subscales that are in line with the literature. The presented normative data offer important advancements for the interpretation of the questionnaire scores and enhance its usefulness for clinical and research applications.

    Full Text Available Depression is a serious mental disorder that is a leading cause of morbidity in the elderly and affects the daily lives of the elderly leading to the marginalization and stigmatization. Purpose: The purpose of this study was to investigate the prevalence of depression in the elderly, both in the community and in closed structures and identify possible differences between these two groups. Material and Method: The studied population consisted of 200 elderly people. One hundred of them came from closed structure care (nursing home and the remaining 100 by Open Care Centres (KAPI. For data collection, a specially designed questionnaire that included demographic data, information about their health and their daily habits and Depression Scale Hamilton, were used. Results: The majority of the sample (50.5% was men. Depressive symptomatology was showed by 44% (31% mild and 13% moderate. The men of the nursing home had greater depression than men of KAPI and showed a greater percentage of women (27.3 % mild and 12.1 % moderate, with women of the nursing home outweighing the percentages of those in KAPI. Depressive symptomatology exhibited by widowers, people with multiple pathology and those who did not exercise, with rates of 61.5%, 34.6% and 73.1% respectively. Big difference appeared between closed and open structure, where the elderly in nursing home seemed to show greater depression by 53%, versus 35% of those in KAPI. Conclusions: Gender, marital status, presence of pathology, exercise and living in closed structures of care, seem to influence the occurrence of depression in the elderly.

    2001-01-01

    The goal of Western blotting, or more correctly, immunoblotting, is to identify with a specific antibody a particular antigen within a complex mixture of proteins that has been fractionated in a polyacrylamide gel and immobilized onto a membrane. Immunoblotting can be used to determine a number of important characteristics of protein antigens-the presence and quantity of an antigen, the relative molecular weight of the polypeptide chain, and the efficiency of extraction of the antigen.Immunoblotting occurs in six stages: (1) extraction and quantification of protein samples; (2) resolution of the protein sample in sodium dodecyl sulfatepolyacrylamide denaturing gel electrophoresis (SDS-PAGE); (3) transfer of the separated polypeptides to a membrane support; (4) blocking nonspecific binding sites on the membrane; (5) addition of antibodies; and (6) detection.Sample preparation is important for obtaining accurate separation of the proteins on the basis of molecular weight. Depending on whether an antigen is primarily extracellular, cytoplasmic, or membrane-associated different procedures might be required to prepare the sample initially. Although there are exceptions, many soluble nuclear and cytoplasmic proteins can be solubilized by lysis buffers that contain the nonionic detergent Nonidet P-40 (NP-40) and either no salt at all or relatively high concentrations of salt (e.g., 0.5 M NaCl). However, the efficiency of extraction is often greatly affected by pH of the buffer and the presence or absence of chelating agents such EDTA.

    2013-01-01

    The purpose of the present study was to assess the factor structure and reliability of the Depression, Anxiety and Stress Scales (DASS-21) in a large Portuguese community sample. Participants were 1020 adults (585 women and 435 men), with a mean age of 36.74 (SD = 11.90) years. All scales revealed good reliability, with Cronbach's alpha values between .80 (anxiety) and .84 (depression). The internal consistency of the total score was .92. Confirmatory factor analysis revealed that the best-fitting model (*CFI = .940, *RMSEA = .038) consisted of a latent component of general psychological distress (or negative affectivity) plus orthogonal depression, anxiety and stress factors. The Portuguese version of the DASS-21 showed good psychometric properties (factorial validity and reliability) and thus can be used as a reliable and valid instrument for measuring depression, anxiety and stress symptoms.

    Sodium dodecyl sulfate (SDS) is one of the main components in the detergent and cosmetic industries. Its bioremediation by suitable microorganism has begun to receive greater attention as the amount of SDS usage increases to a point where treatment plants would not be able to cope with the increasing amount of SDS in wastewater. The purpose of this work was to isolate local SDS-degrading bacteria. Screening was carried out by the conventional enrichment-culture technique. Six SDS-degrading bacteria were isolated. Of these isolates, isolate S14 showed the highest degradation of SDS with 90% degradation after three days of incubation. Isolate S14 was tentatively identified as Klebsiella oxytoca strain DRY14 based on carbon utilization profiles using Biolog GN plates and partial 16S rDNA molecular phylogeny. SDS degradation by the bacterium was optimum at 37 degrees 0. Ammonium sulphate; at 2.0 g l(-1), was found to be the best nitrogen source for the growth of strain DRY14. Maximum growth on SDS was observed at pH 7.25. The strain exhibited optimum growth at SDS concentration of 2.0 g l(-1) and was completely inhibited at 10 g l(-1) SDS. At the tolerable initial concentration of 2.0 g l(-1), almost 80% of 2.0 g l(-1) SDS was degraded after 4 days of incubation concomitant with increase in cellular growth. The K(m(app) and V(max(app)) values calculated for the alkylsulfatase from this bacterium were 0.1 mM SDS and 1.07 micromol min(-1) mg(-1) protein, respectively.

    Full Text Available Aims: Depression is one of the most common mental disorders in children, and in adolescents, as in adults. Once its occurrence during childhood and adolescence leads to serious consequences in adulthood, its early detection is an important goal. Self-report instruments have a key role on accessing thoughts, feelings and behaviors in an easily, reliably and validly way. The aim of the current study is to assess psychometric properties (reliability and validity of the Portuguese translation of the Center for Epidemiological Studies-Depression Scale for Children (CES-DC. Methods: A school-based sample of 417 adolescents aged 12–18 years (M = 15,20, SD = 1,72 was involved in this study. Translation and Back Translation was made. To study convergent and divergent validity there were used the Portuguese versions of the Depression Anxiety Stress Scales (DASS 21, of the Children's Depression Inventory (CDI, and of the Students' Life Satisfaction Scale (SLSS which measure, respectively, negative emotional states (depression, anxiety and stress, depressive symptoms and global life satisfaction. Results: Factor analysis revealed three factors (mood, interpersonal relationships and happiness that explain 54% of the variance. The results show that the scale has an excellent internal consistency (α = 0,90, good temporal stability (r = 0,72 as an adequate convergent and divergent validity. Results showed that depressive symptoms varied in function of age and gender. Conclusions: The results of the present study provide initial adequate validity and reliability of the CES-DC. Nevertheless some limitations to this study, the results suggest that CES-DC can be a useful questionnaire in the assessment of depressive symptoms in Portuguese adolescents.

Objective measures, such as the Attitudes Towards Depression and its Treatments scale (ATDT, have been developed to assess such attitudes. The aims of this research were to test the reliability and validity of ATDT on an Australian sample who were not depressed during the study or who had previously been depressed, to explore the attitudes of the Australian public towards depression, and to compare these attitudes to those of a Canadian sample of people with depression.Methods: A sample of 63 males and 140 females (mean age = 32.2 years, SD = 12.9 years from Melbourne, Australia took part in this study. Fourteen of the males and 52 of the female participants (mean age = 35.4 years, SD = 13.2 years stated that they had been previously diagnosed with depression.Results: The attitudes of the Australian sample and the subset of that sample who had previously experienced depression differed from those of the Canadian outpatient sample: they were less ashamed of depression, more likely to take antidepressants and consider psychotherapy, and more likely to seek help from professionals or significant others in their lives. However, those in the Australian sample were more likely to report that antidepressants made them lose control, and they were less willing to consider electric shock as a treatment option for their depression.

    This study aimed to evaluate the psychometric properties of the Korean version of the Clinically Useful Anxiety Outcome Scale (CUXOS) and to examine the current diagnostic comorbidity and differential severity of anxiety symptoms between major depressive disorder (MDD) and anxiety disorders. In total, 838 psychiatric outpatients were analyzed at their intake appointment. Diagnostic characteristics were examined using the structured clinical interview from the DSM-IV because the DSM5 was not available at the start of the study. The CUXOS score was measured and compared with that of 3 clinician rating scales and 4 self-report scales. The CUXOS showed excellent results for internal consistency (Cronbach's α = 0.90), test-retest reliability (r = 0.74), and discriminant and convergent validity. The CUXOS significantly discriminated between different levels of anxiety severity, and the measure was sensitive to change after treatment. Approximately 45% of patients with MDD were additionally diagnosed with anxiety disorders while 55% of patients with anxiety disorders additionally reported an MDD. There was a significant difference in CUXOS scores between diagnostic categories (MDD only, anxiety only, both disorders, and no MDD or anxiety disorder). The CUXOS scores differed significantly between all categories of depression (major, minor, and non-depression) except for the comparison between minor depression and non-depression groups. The Korean version of the CUXOS is a reliable and valid measure of the severity of anxiety symptoms. The use of the CUXOS could broaden the understanding of coexisting and differentiating characteristics of anxiety and depression.

    Experimental investigations were carried out on the spreading of small drops of aqueous SDS solutions over dry thin porous substrates (nitrocellulose membranes) in the case of partial wetting. The time evolution was monitored of the radii of both the drop base and the wetted area inside the porous substrate. The total duration of the spreading process was subdivided into three stages: the first stage: the drop base expands until the maximum value of the drop base is reached, the contact angle rapidly decreases during this stage; the second stage: the radius of the drop base remains constant and the contact angle decreases linearly with time; the third stage: the drop base shrinks and the contact angle remains constant. The wetted area inside the porous substrate expends during the whole spreading process. Appropriate scales were used with a plot of the dimensionless radii of the drop base, of the wetted area inside the porous substrate and the dynamic contact angle on the dimensionless time. Our experimental data show: the overall time of the spreading of drops of SDS solution over dry thin porous substrates decreases with the increase of surfactant concentration; the difference between advancing and hydrodynamic receding contact angles decreases with the surfactant concentration increase; the constancy of the contact angle during the third stage of spreading has nothing to do with the hysteresis of contact angle, but determined by the hydrodynamic reasons. It is shown using independent spreading experiments of the same drops on nonporous nitrocellulose substrate that the static receding contact angle is equal to zero, which supports our conclusion on the hydrodynamic nature of the hydrodynamic receding contact angle on porous substrates.

    Full Text Available Abstract Background Depression and anxiety are recognised increasingly as serious public health problems among women in low- and lower-middle income countries. The aim of this study was to validate the 21-item Depression Anxiety and Stress Scale (DASS21 for use in screening for these common mental disorders among rural women with young children in the North of Vietnam. Methods The DASS-21 was translated from English to Vietnamese, culturally verified, back-translated and administered to women who also completed, separately, a psychiatrist-administered Structured Clinical Interview for DSM IV Axis 1 diagnoses of depressive and anxiety disorders. The sample was a community-based representative cohort of adult women with young children living in Ha Nam Province in northern Viet Nam. Cronbach’s alpha, Exploratory Factor Analyses (EFA and Receiver Operating Characteristic (ROC analyses were performed to identify the psychometric properties of the Depression, Anxiety, and Stress subscales and the overall scale. Results Complete data were available for 221 women. The internal consistency (Cronbach’s alpha of each sub-scale and the overall scale were high, ranging from 0.70 for the Stress subscale to 0.88 for the overall scale, but EFA indicated that the 21 items all loaded on one factor. Scores on each of the three sub-scales, and the combinations of two or three of them were able to detect the common mental disorders of depression and anxiety in women with a sensitivity of 79.1% and a specificity of 77.0% at the optimal cut off of >33. However, they did not distinguish between those experiencing only depression or only anxiety. Conclusions The total score of the 21 items of the DASS21-Vietnamese validation appears to be comprehensible and sensitive to detecting common mental disorders in women with young children in primary health care in rural northern Vietnam and therefore might also be useful to screen for these conditions in other resource

    BACKGROUND: In long-term follow-up studies on depression, the Eysenck Neuroticism Scale (ENS) at the score level of dysthymia has been found to be valid at predicting poor outcome. AIMS: The ENS dysthymia level was compared with the Beck Depression Inventory (BDI) level to predict the prevalence......, and HAM-D from 2005-2007. At 5-year follow-up from 2011-2013, the participants were re-assessed by HAM-D. The HAM-D was used to measure depressive symptoms at the 5-year follow-up. The Mokken analysis was used to indicate scalability of the BDI and ENS. RESULTS: A total of 185 participants were available...... as measured by the two self-rating scales ENS and BDI can be considered part of a 'double depression' in patients with first episode depression, implying an existence of depressive symptoms at the 5-year follow-up.

    Full Text Available Abstract Background There is a growing awareness of the need for easily administered, psychometrically sound screening tools to identify individuals with elevated levels of psychological distress. Although support has been found for the psychometric properties of the Depression, Anxiety and Stress Scales (DASS using classical test theory approaches it has not been subjected to Rasch analysis. The aim of this study was to use Rasch analysis to assess the psychometric properties of the DASS-21 scales, using two different administration modes. Methods The DASS-21 was administered to 420 participants with half the sample responding to a web-based version and the other half completing a traditional pencil-and-paper version. Conformity of DASS-21 scales to a Rasch partial credit model was assessed using the RUMM2020 software. Results To achieve adequate model fit it was necessary to remove one item from each of the DASS-21 subscales. The reduced scales showed adequate internal consistency reliability, unidimensionality and freedom from differential item functioning for sex, age and mode of administration. Analysis of all DASS-21 items combined did not support its use as a measure of general psychological distress. A scale combining the anxiety and stress items showed satisfactory fit to the Rasch model after removal of three items. Conclusion The results provide support for the measurement properties, internal consistency reliability, and unidimensionality of three slightly modified DASS-21 scales, across two different administration methods. The further use of Rasch analysis on the DASS-21 in larger and broader samples is recommended to confirm the findings of the current study.

    Objective: To explore the relation among depression, coping styles and personality in major depression. Methods:87 major depression patients and 90 normal controls were assessed by Self- Rating Depression Scale (SDS), Eysenck Personality Questionnaire and Coping Styles Questionnaire. Results: The patients were found with higher scores in Neuroticism and Psychoti-cism, and lower in Extrovision and positive coping styles than normal controls. Significant relationship was found among depres-sion, extrovision, psychoticism and positive coping styles. The last three accounted for 36.8 % of the variance of depression in major depression. Conclusion: The patients scored high in neuroticism and psychoticism, and low in extorvision and positive cop-ing styles. The application of little positive coping styles may be a part of extrovision and/or psychoticism in major depression.

    Although increased reactive oxygen species (ROS) is caused by stress accelerates collagen degradation, there was no data on the relationship between stress and urinary hydroxyproline (Hyp) and proline (Pro), a good marker of collagen degradation. The purpose of this study was to evaluate the relationship between depression, anxiety, and stress (DAS) and concentrations of urinary Hyp and Pro. 97 hospital employees aged 20 to 58 were asked to fill out comprehensive self-administrated questionnaires containing information about their medical history, lifestyle, length of the work year, shift-work and DAS. depression anxiety stress scale (DASS) was applied to evaluate chronic mental disorders. Urine samples were analyzed using high performance liquid chromatography (HPLC) with double derivatization for the assay of hydroxyproline and proline. The mean value of Hyp and Pro concentration in all subjects was 194.1 ± 113.4 μmol/g and 568.2 ± 310.7 μmol/g. DASS values and urinary Pro concentrations were differentiated by sex (female > male, p others, p stress (Adjusted r2 = 0.051) and anxiety and job (Adjusted r2 = 0.199), respectively. We found that stress and anxiety were correlated with urinary Hyp and Pro concentrations. To identifying a definite correlation, further study in large populations will be needed.

    This paper examines the clinical utility of the Hospital Anxiety and Depression Scale (HADS) in the context of evaluating the Fibromyalgia Outpatient Education Program at Southlake Regional Health Centre (Newmarket, Canada). A pre-test/post-test design was implemented for data analysis. A total of 232 patients' data were obtained through retrospective patient chart review. Complete pre-post data were available for 70 patients and qualitative analysis was done for 12 patients. Main outcome measures included HADS and Arthritis Self-Efficacy (ASE) scores. At the end of the education program, subgroups of patients (high attendance, high exercise habit, low medication) experienced significant improvement on HADS-depression and ASE scores. Linear regression analysis found that HADS pre-program scores explain far more variance in HADS post-test scores than ASE pre-program scores explain in ASE post-program scores; more variance in ASE post-program scores was explained by other variables. In contrast to the quantitative analysis of the Anxiety subscale of HADS, patients in the focus group indicated that their anxiety level decreased through attending the education program. These findings suggest that HADS is an appropriate tool for evaluating fibromyalgia and related patient education programs. Moreover, patient education programs have positive effects on enhancing patients' psychological well-being and self-confidence in controlling fibromyalgia-related symptoms.

    Full Text Available OBJECTIVE: Evaluate the accuracy of diagnosis of major depression in patients with Parkinson's disease (PD using the UPDRS, the 15-item Geriatric Depression Scale (GDS15 and the Beck Depression Inventory (BDI. METHOD: 50 consecutive patients with PD were evaluated. The diagnosis of major depression was made according to the DSM-IV criteria. RESULTS: We found a 24% prevalence of major depression. All depression scales were highly correlated but UPDRS depression item had the lowest diagnostic value. The GDS15 had the more appropriate "receiver operating characteristics" curve. The best cut-off scores for screening depression were 17/18 for BDI and 8/9 for GDS15. We did not find any correlation between the level of depression and intensity of motor symptoms, functional capacity and duration of the disease. CONCLUSION: GDS15 is better than the BDI and the UPDRS for screening depression in PD and depression is not related to the degree of parkinsonian symptoms.OBJETIVO: Avaliar a precisão do diagnóstico de depressão em pacientes com doença de Parkinson avaliados pela UPDRS, pela Escala Geriátrica de Depressão com 15 itens (EGD15 e pelo Inventário de Depressão de Beck (IDB. MÉTODO: 50 pacientes com DP foram avaliados. O diagnóstico de depressão maior foi feito segundo os critérios do DSM-IV. RESULTADOS: A prevalência de depressão foi 24%. As escalas de depressão tiveram elevada correlação entre si. A UPDRS apresentou a menor sensibilidade para o diagnóstico. A EGD15 mostrou uma curva ROC mais apropriada que o IDB. Os melhores escores-de-corte para diagnóstico de depressão foram 17/18 para o IDB e 8/9 para a EGD15. Não houve correlação entre os níveis de depressão e a intensidade do parkinsonismo, a capacidade funcional ou a duração da doença. CONCLUSÃO: A EGD15 é melhor que o IDB para diagnosticar depressão na DP. A depressão não está relacionada à gravidade dos sintomas parkinsonianos.

    From the moment Max Hamilton started his psychiatric education, he considered psychometrics to be a scientific discipline on a par with biochemistry or pharmacology in clinical research. His clinimetric skills were in operation in the 1950s when randomised clinical trials were established...... as the method for the evaluation of the clinical effects of psychotropic drugs. Inspired by Eysenck, Hamilton took the long route around factor analysis in order to qualify his scales for anxiety (HAM-A) and depression (HAM-D) as scientific tools. From the moment when, 50 years ago, Hamilton published his first...... placebo-controlled trial with an experimental anti-anxiety drug, he realized the dialectic problem in using the total score on HAM-A as a sufficient statistic for the measurement of outcome. This dialectic problem has been investigated for more than 50 years with different types of factor analyses without...

    Eysenck and Eysenck identified the two-factor structure of personality, namely neuroticism and extraversion which has been widely used in clinical psychiatry, and generated much research on the psychometric properties of the scales. Using a classical psychometric approach the neuroticism...... and extraversion scales have shown robust psychometric properties. The present study used both classical psychometric and item response theory (IRT) analyses to evaluate the neuroticism and extraversion scales and improve scalability of the instrument neuroticism and extraversion. A first time depressed sample...... symptoms related to interpersonal sensitivity were identified. For the extraversion scale a shorter and psychometrically more robust version was identified together with a short introversion scale. Clinically discriminant validity was analysed using correlations. The correlation between depression (Ham...

The data were obtained from a sample of 300 university students. The internal consistency values for the TDEP were high (.90. The test-retest values from eight weeks time interval (fifty six days were elevated (.78. A factorial analysis of the principal components revealed a principal factor for all of the constructed items in this experimental version of the TDEP. The last, promax rotation showed two clear main factors similar in size: negative affectivity (Dysthymia and positive affectivity (Euthymia. The convergent validity indexes for the Beck Depression Inventory and the Zung Self Rating Depression Scale, were also high, with indexes ranging from .64 to .71. The correlation between State- Trait Anxiety Inventory and the depression scales used in this study was high (between .63 and .78, once again indicating the usual overlapping between anxiety and depression seen in most depression inventories.

    Full Text Available The Center for Epidemiological Studies-Depression (CES-D scale is a widely used measure of depressive symptoms, but its psychometric properties have not been adequately evaluated among adults with HIV/AIDS. This study used an item response theory approach (Rasch analysis to evaluate the CES-D’s validity and reliability in relation to key demographic and clinical variables in adults with HIV/AIDS. A convenience sample of 347 adults with HIV/AIDS (231 males, 93 females, and 23 transgenders; age range 22–77 years completed the CES-D. A Rasch model application was used to analyze the CES-D’s rating scale functioning, internal scale validity, person-response validity, person-separation validity, internal consistency, differential item functioning (DIF, and differential test functioning. CES-D scores were generally high and associated with several demographic and clinical variables. The CES-D distinguished 3 distinct levels of depression and had acceptable internal consistency but lacked unidimensionality, five items demonstrated poor fit to the model, 15% of the respondents demonstrated poor fit, and eight items demonstrated DIF related to gender, race, or AIDS diagnosis. Removal of misfitting items resulted in minimal improvement in the CES-D’s substantive and structural validity. CES-D scores should be interpreted with caution in adults with HIV/AIDS, particularly when comparing scores across gender and racial groups.

    To compare the Edinburgh Postnatal Depression Scale (EPDS) and Patient Health Questionnaire (PHQ-9) as screening tools for postpartum depression. This study population included the first 500 women to enroll and return their packets during an ongoing study of postpartum depression. The primary outcome of this study was to find rates of concordance and discordance in the EPDS and PHQ-9 categories of "normal" and "increased risk for major depressive disorder." Overall, 97% of eligible women enrolled and 70% returned the packets that included the EPDS and PHQ-9. Four hundred eighty-one of the first 500 packets had complete data, with elevated EPDS or PHQ-9 scores in 138 and 132 women, respectively. Concordance of the EPDS and PHQ-9 were present in 399 women (83%): 326 (67.8%) had "normal" score on both, and 73 (15.2%) had elevated scores for both. Discordant scores in 82 women included 17 with elevated PHQ-9 scores but normal EPDS scores and 65 with elevated EPDS scores and PHQ-9 scores 30 and low education level were predictive of discordant scores, using EPDS and PHQ-9 scores of > or =10 as elevated (odds ratio, 1.9 and P = .02; and odds ratio, 2.3 and P = .01, respectively). PHQ-9 scores of 5 to 9 have been referred to as consistent with "mild depressive symptoms" and appropriate for "watchful waiting" and repeat PHQ-9 at follow-up. Using this follow-up approach would require re-evaluation of 120 (25%) of the women screened. Postpartum depression screening is feasible in primary care practices, and for most women the EPDS and PHQ-9 scores were concordant. Further work is required to identify reasons for the 17% discordant scores as well as to provide definitive recommendations for PHQ-9 scores of 5 to 9.

    Full Text Available BACKGROUND: The hospital anxiety and depression scale (HADS is a widely used instrument for evaluating psychological distress from anxiety and depression. HADS has not yet been validated in Ethiopia. The aim of this study was to evaluate the reliability and validity of the Amharic (Ethiopian language version of HADs among HIV infected patients. METHODS: The translated scale was administered to 302 HIV/AIDS patients on follow up for and taking anti-retroviral treatment. Consistency assessment was conducted using Cronbach's alpha, test-retest reliability using intra-class correlation coefficients (ICC. Construct validity was examined using principal components analysis (PCA. Parallel analysis, Kaiser's criterion and the scree test were used for factor extraction. RESULTS: The internal consistency was 0.78 for the anxiety, 0.76 for depression subscales and 0.87 for the full scale of HADS. The intra-class correlation coefficient (ICC was 80%, 86%, and 84% for the anxiety and depression subscales, and total score respectively. PCA revealed a one dimensional scale. CONCLUSION: This preliminary validation study of the Ethiopian version of the HADs indicates that it has promising acceptability, reliability and validity. The adopted scale has a single underlying dimension as indicated by Razavi's model. The HADS can be used to examine psychological distress in HIV infected patients. Findings are discussed and recommendations made.

    This protocol describes a method for RNA purification by sodium dodecyl sulfate (SDS) solubilization and phenol extraction. It is of wide utility and is used routinely to deproteinize RNAs in biological material that has been solubilized in SDS, an ionic detergent that dissolves membranes, disrupts protein-nucleic acid interactions, and inactivates ribonucleases. Once solubilized, addition of phenol or phenol:chloroform:isoamyl alcohol (PCA) completely denatures the protein, and it becomes insoluble in aqueous solution. PCA extraction is the method of choice for preparing cytoplasmic RNA from tissue culture cells or in any other situation (e.g., enzyme reactions) where solubilization in SDS is easily achievable.

    Full Text Available Abstract Background Early detection of common mental disorders, such as depression and anxiety, among children and adolescents requires the use of validated, culturally sensitive, and developmentally appropriate screening instruments. The Arab region has a high proportion of youth, yet Arabic-language screening instruments for mental disorders among this age group are virtually absent. Methods We carried out construct and clinical validation on the recently-developed Arab Youth Mental Health (AYMH scale as a screening tool for depression/anxiety. The scale was administered with 10-14 year old children attending a social service center in Beirut, Lebanon (N = 153. The clinical assessment was conducted by a child and adolescent clinical psychiatrist employing the DSM IV criteria. We tested the scale's sensitivity, specificity, and internal consistency. Results Scale scores were generally significantly associated with how participants responded to standard questions on health, mental health, and happiness, indicating good construct validity. The results revealed that the scale exhibited good internal consistency (Cronbach's alpha = 0.86 and specificity (79%. However, it exhibited moderate sensitivity for girls (71% and poor sensitivity for boys (50%. Conclusions The AYMH scale is useful as a screening tool for general mental health states and a valid screening instrument for common mental disorders among girls. It is not a valid instrument for detecting depression and anxiety among boys in an Arab culture.

    Depression screening in patients with cancer is recommended by major clinical guidelines, although the evidence on individual screening tools is limited for this population. Here, the authors assess and compare the diagnostic accuracy of 2 established screening instruments: the depression modules of the 9-item Patient Health Questionnaire (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS-D), in a representative sample of patients with cancer. This multicenter study was conducted with a proportional, stratified, random sample of 2141 patients with cancer across all major tumor sites and treatment settings. The PHQ-9 and HADS-D were assessed and compared in terms of diagnostic accuracy and receiver operating characteristic (ROC) curves for Diagnostic and Statistical Manual of Mental Disorders, 4th edition diagnosis of major depressive disorder using the Composite International Diagnostic Interview for Oncology as the criterion standard. The diagnostic accuracy of the PHQ-9 and HADS-D was fair for diagnosing major depressive disorder, with areas under the ROC curves of 0.78 (95% confidence interval, 0.76-0.79) and 0.75 (95% confidence interval, 0.74-0.77), respectively. The 2 questionnaires did not differ significantly in their areas under the ROC curves (P = .15). The PHQ-9 with a cutoff score ≥7 had the best screening performance, with a sensitivity of 83% (95% confidence interval, 78%-89%) and a specificity of 61% (95% confidence interval, 59%-63%). The American Society of Clinical Oncology guideline screening algorithm had a sensitivity of 44% (95% confidence interval, 36%-51%) and a specificity of 84% (95% confidence interval, 83%-85%). In patients with cancer, the screening performance of both the PHQ-9 and the HADS-D was limited compared with a standardized diagnostic interview. Costs and benefits of routinely screening all patients with cancer should be weighed carefully. Cancer 2017. © 2017 American Cancer Society. © 2017 American Cancer Society.

    Depression and anxiety are two common mental health problems among older people. There is evidence that using well-validated screening tools can improve detection of depression and anxiety among this group. The review explored the use of the Geriatric Depression Scale (GDS) and the Geriatric Anxiety Inventory (GAI) for screening depression and anxiety among older Chinese immigrants, one of the largest and fastest growing groups of older immigrants in Western society. It focused on the GDS and GAI because both are designed specifically for older people. Online literature searches were conducted in MEDLINE, CINAHL, and PsycINFO. A narrative approach was used to review included papers. A total of 21 articles were included. There were limited data on anxiety among older Chinese immigrants, with only one unpublished report identified. There were 13 studies (20 articles) using the GDS with this group. Results of these studies indicated that the GDS is a reliable tool in this population; however, there was limited validity data. Two versions of the GDS-15 have been used with older Chinese immigrants, including the standard GDS-15 and Mui's GDS-15. Prevalence of depression ranged between 20% and 30% in most reviewed studies. Results of this review have practical implications for clinicians in their use of these tools with older Chinese immigrants in Western countries, such as the different GDS versions. It also suggests a number of directions for future research, such as the inclusion of clinical samples and consideration of the diversity within this group. © 2015 Wiley Publishing Asia Pty Ltd.

    Full Text Available Abstract Background How epithelial cells adopt their particular polarised forms is poorly understood. In a screen for genes regulating epithelial morphology in Drosophila, we identified sds22, a conserved gene previously characterised in yeast. Results In the columnar epithelia of imaginal discs or follicle cells, mutation of sds22 causes contraction of cells along their apical-basal axis, resulting in a more cuboidal morphology. In addition, the mutant cells can also display altered cell polarity, forming multiple layers in follicle cells and leaving the epithelium in imaginal discs. In yeast, sds22 encodes a PP1 phosphatase regulatory subunit. Consistent with this, we show that Drosophila Sds22 binds to all four Drosophila PP1s and shares an overlapping phenotype with PP1beta9c. We also show that two previously postulated PP1 targets, Spaghetti Squash and Moesin are hyper-phosphorylated in sds22 mutants. This function is shared by the human homologue of Sds22, PPP1R7. Conclusion Sds22 is a conserved PP1 phosphatase regulatory subunit that controls cell shape and polarity.

    Full Text Available Background: Psychometrically sound measurement instrument is a fundamental requirement across broad range of research areas. In negative affect research, Depression Anxiety Stress Scale (DASS has been identified as a psychometrically sound instrument to measure depression, anxiety and stress, especially the 21-item version. However, its psychometric properties in adolescents have been less consistent. Objectives: Thus, the present study sought to examine the factorial validity and internal consistency of the adapted 21-item version of DASS in Malaysian adolescents. Method: Using cross-sectional study design, DASS-21 was administered to 750 Malaysian adolescents (Mean age = 13.40 ± 0.49. The data were then analyzed using Confirmatory factor analysis (CFA, in which the original DASS-21 factor structure (depression-stress-anxiety was compared to 8 other alternative models.Results: CFA results revealed a weak support for DASS-21 as a differentiated measure of depression, anxiety and stress in Malaysian adolescents. Extremely high latent factors intercorrelations were observed in the model reflecting original DASS factor structure. On the other hand, despite the best overall fit of a 4-factor model consisting of depression, anxiety, and stress, as well as a general negative affect factor, individual factor loadings for the specific factors were uninterpretable. Although model fit of 1-factor model was inferior when compared the other competing models, this model (1-factor exhibit reasonable model fit. Conclusion: We concluded that the use of Malaysian adapted DASS-21 as a differentiated measure stress, anxiety, and depression in Malaysian adolescent should proceed with caution and further refinement of the scale is necessary before a concrete conclusion can be made.

    The Depression Anxiety Stress Scales-21 (DASS-21) is the short version of a self-report measure that was originally developed to provide maximum differentiation between depressive and anxious symptoms. Despite encouraging evidence, the factor structure and other features of the DASS-21 are yet to be firmly established. A community sample of 417 participants and two clinical groups (32 depressive patients and 25 anxious patients) completed the Italian version of the DASS-21 along with several measures of psychopathology. Confirmatory factor analyses suggested that the DASS-21 is a measure of general distress plus three additional orthogonal dimensions (anxiety, depression, and stress). The internal consistency and temporal stability of the measure were good; each DASS-21 scale correlated more strongly with a measure of a similar construct, demonstrating good convergent and divergent validity. Lastly, the DASS-21 demonstrated good criterion-oriented validity. The validity of the Italian DASS-21 and its utility, both for community and clinical individuals, are supported.

We recruited 469 nonclinical participants in China. They completed the Chinese version temperament and character inventory (TCI and self-rating depression scale (SDS. A structural equation model was used to rate the relation between seven TCI scales and the three SDS subscale scores (based on Shafer's meta-analysis of the SDS items factor analyses. This was based on the assumption that the three depression subscales would be predicted by the temperament and character subscales, whereas the character subscales would be predicted by the temperament subscales. Results. The positive symptoms scores were predicted by low self-directedness (SD, cooperativeness (C, reward dependence (RD, and persistence (P as well as older age. The negative symptoms scores were predicted only by an older age. The somatic symptoms scores were predicted by high SD. Conclusion. Syndromes of depression are differentially associated with temperament and character patterns. It was mainly the positive symptoms scores that were predicted by the TCI scores. The effects of harm avoidance (HA on the positive symptoms scores could be mediated by low SD and C.

    Full Text Available OBJECTIVE: To establish the reliability and validity of a shortened (10-item depression scale used among HIV-positive patients enrolled in the Drug Treatment Program in British Columbia, Canada. METHODS: The 10-item CES-D (Center for Epidemiologic Studies Depression Scale was examined among 563 participants who initiated antiretroviral therapy (ART between August 1, 1996 and June 30, 2002. Internal consistency of the scale was measured by Cronbach's alpha. Using the original CES-D 20 as primary criteria, comparisons were made using the Kappa statistic. Predictive accuracy of CES-D 10 was assessed by calculating sensitivity, specificity, positive predictive values and negative predictive values. Factor analysis was also performed to determine if the CES-D 10 contained the same factors of positive and negative affect found in the original development of the CES-D. RESULTS: The correlation between the original and the shortened scale is very high (Spearman correlation coefficient  =0.97 (P<0.001. Internal consistency reliability coefficients of the CES-D 10 were satisfactory (Cronbach α=0.88. The CES-D 10 showed comparable accuracy to the original CES-D 20 in classifying participants with depressive symptoms (Kappa=0.82, P<0.001. Sensitivity of CES-D 10 was 91%; specificity was 92%; and positive predictive value was 92%. Factor analysis demonstrates that CES-D 10 contains the same underlying factors of positive and negative affect found in the original development of the CES-D 20. CONCLUSION: The 10-item CES-D is a comparable tool to measure depressive symptoms among HIV-positive research participants.

    Purpose. Depression prevalence and risk increase among adolescents are related to biological, psychosocial, and cultural factors. Little is known about the association between cognitive distortion, type D personality, family environment, and depression. The aim of this paper was to examine the relationships of cognitive distortion, type D personality, family environment, and depression in a sample of Chinese adolescents. Methods. A sample of Chinese adolescents with depression and the controls were investigated cross-sectionally with life orientation test-revised (LOT-R), type D personality Scale-14 (DS14), family environment scale (FES), and Zung self-depression scale (SDS); respectively, all scales were administered in Chinese. Results. Chinese-depressed adolescents showed more cognitive distortion, type D personality, and adverse family environment than control groups. Furthermore, lower level of Optimism, negative affectivity, and poor family cohesion may increase the risk of depression in Chinese adolescents. Conclusions. Our study indicates that lower level of Optimism, Negative Affectivity, and poor Family Cohesion factors were implicated to contribute to depression in Chinese adolescents. Lower level of optimism and negative affectivity may be crucial associated factors of depression among these samples. our findings pointed to the importance of broad screening and intervention of vulnerable population.

    The problems of mood disorders are critical in people with epilepsy. Therefore, there is a need to validate a useful tool for the population. The Hospital Anxiety and Depression Scale (HADS) has been used on the population, and showed that it is a satisfactory screening tool. However, more evidence on its construct validity is needed. A total of 1041 people with epilepsy were recruited in this study, and each completed the HADS. Confirmatory factor analysis (CFA) and Rasch analysis were used to understand the construct validity of the HADS. In addition, internal consistency was tested using Cronbachs' α, person separation reliability, and item separation reliability. Ordering of the response descriptors and the differential item functioning (DIF) were examined using the Rasch models. The HADS showed that 55.3% of our participants had anxiety; 56.0% had depression based on its cutoffs. CFA and Rasch analyses both showed the satisfactory construct validity of the HADS; the internal consistency was also acceptable (α=0.82 in anxiety and 0.79 in depression; person separation reliability=0.82 in anxiety and 0.73 in depression; item separation reliability=0.98 in anxiety and 0.91 in depression). The difficulties of the four-point Likert scale used in the HADS were monotonically increased, which indicates no disordering response categories. No DIF items across male and female patients and across types of epilepsy were displayed in the HADS. The HADS has promising psychometric properties on construct validity in people with epilepsy. Moreover, the additive item score is supported for calculating the cutoff. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    This study was designed to determine whether scores on selected Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scales could be used to differentiate between individuals diagnosed with schizophrenia (SCZ) and major depressive disorder (MDD). The sample was drawn from 2 psychiatric inpatient hospitals and included data from 199 individuals with SCZ and 808 individuals with MDD. A series of multivariate analyses of variance, analyses of variance, and odds ratios were calculated to determine which MMPI-2-RF scales provide the best differentiation between individuals presenting with these 2 disorders. Results indicated scales assessing internalizing dysfunction, including Emotional/Internalizing Dysfunction (EID), Restructured Clinical Scales Demoralization (RCd), Low Positive Emotions (RC2), Suicidal/Death Ideation (SUI), and Self Doubt (SFD) best discriminated MDD from SCZ. Scales assessing thought dysfunction, incluidng Thought Dysfunction (THD), Restructured Clinical Scales Ideas of Persecution (RC6) and Aberrant Experiences (RC8), and Psychoticism-Revised (PSYC-r) were demonstrated to best identify SCZ. Comparisons of the examined MMPI-2-RF scales to MMPI-2 scales assessing similar constructs suggested scales from the MMPI-2-RF perform similarly to their MMPI-2 counterparts in detecting MDD or SCZ, but might have increased ability to discriminate SCZ from other conditions. Overall, results of this study suggest that scores on the examined MMPI-2-RF scales provide important information about the differential diagnosis of MDD and SCZ to clinicians working in inpatient settings.

    With the development of the Behavioral Activation for Depression Scale (BADS) by Kanter, et al. [1], different behavioral aspects of depression like activation, rumination or avoidance, and functional impairment can be measured. The long and the short versions of the BADS, however, show differences in the quality of psychometric properties. We wanted to validate the short and long forms of the BADS. We therefore evaluated the factor structure, the psychometric properties, and the construct validity of the long version and the subscales in a clinically depressed German sample (n=258) in study 1. In study 2, we explored the factor structure and the psychometric properties of the short version of the BADS in a subsyndromal sample with elevated depressive symptoms (n=406). In study 1, our results replicated the four factor solution of the BADS-25 original version and showed good psychometric properties. However, with regard to the BADS-9 only the French factor solution of the short BADS-9 demonstrated acceptable fit with low internal consistency of the subscale Avoidance. Thus, only the total score of the short form can be recommended.

    ). METHODS: The first treatment step (Level 1) in the STAR*D study provided a dataset of 4041 outpatients with DSM-IV nonpsychotic major depression. The HAM-D(17) and IDS-C(30) were evaluated by principal component analysis (PCA) without rotation. Mokken analysis tested the unidimensionality of the IDS-C(6......), which corresponds to the unidimensional HAM-D(6.) RESULTS: For both the HAM-D(17) and IDS-C(30), PCA identified a bi-directional factor contrasting the depressive symptoms versus the neurovegetative symptoms. The HAM-D(6) and the corresponding IDS-C(6) symptoms all emerged in the depression factor. Both...... the HAM-D(6) and IDS-C(6) were found to be unidimensional scales, i.e., their total scores are each a sufficient statistic for the measurement of depressive states. LIMITATIONS: STAR*D used only one medication in Level 1. CONCLUSIONS: The unidimensional HAM-D(6) and IDS-C(6) should be used when evaluating...

The present study’s aim is to determine normative values of alertness on the THAT and to explore the relationship among excessive daytime sleepiness, fatigue, depressive symptoms, and alertness. Methods: Normative data were collected from 60 healthy males and females. To explore the relationship among alertness, daytime sleepiness, fatigue, depression, and anxiety, data were collected from charts of sleep clinic patients. All study subjects completed measures for fatigue, sleepiness, depressive symptoms, and anxiety. Results: The average score on the THAT was 34.9±7.2 (range 22–50 for the control group. The cutoff score for the THAT, indicative of clinically significant reduced alertness, was determined to be ≤20.5 (mean –2 SD. THAT alertness scores were found to be modestly, significantly, and negatively correlated with fatigue levels (r=–0.39, P<0.001, depressive symptoms (r=–0.53, P<0.001, and anxiety symptoms (r=–0.41, P<0.001. No correlations were found between alertness levels and daytime sleepiness. Regression analyses revealed a significant model (F=19.9, P<0.001, adjusted R2=0.35 with depressive symptoms (P<0.001 and fatigue (P=0.006 emerging as the only significant predictors of scores on the THAT. Conclusion: The findings of this study support that sleepiness is not the same as

    To investigate (1) the diagnostic value of the Signs of Depression Scale (SODS) in a Likert scale format and (2) whether the Likert scale improves the diagnostic value compared with the original dichotomous scale. Cross-sectional multicentre study. One general and one university hospital in the Netherlands. A total of 116 consecutive hospitalized stroke patients, of whom 53 were patients with communicative impairment. Depression was diagnosed with the Composite International Diagnostic Interview (CIDI) administered to the patients' relatives. The Barthel Index (BI) was used as an external validator. The correlation between the CIDI and the SODS-Likert or the SODS was small ( rb = 0.18), and the correlation between the Barthel Index and the SODS-Likert ( rs = -0.30) or the SODS ( rs = -0.33) was moderate. For both instruments, the discriminatory power for diagnosing depression when compared with the CIDI was best at a cut-off score of ⩾2. The internal consistency of the SODS-Likert was acceptable (α = 0.69) and slightly higher than that of the SODS (α = 0.57). The inter-rater reliability of the SODS-Likert and the SODS was acceptable (intraclass correlation coefficient (ICC) 0.66 and ICC 0.80, respectively). The clinical utility was rated good. The diagnostic value of the SODS did not improve using a Likert scale format. However, the diagnostic value of the original dichotomous SODS is reasonable for the initial mood assessment of stroke patients with communicative impairment.

This study aimed to contribute to the validation of the Portuguese version of this tool and analyze its psychometric characteristics in comparison with other self-report instruments for depression in adolescents, in Portugal. Two samples were collected, a non-clinical group of in school youth (n=773; 52.4% male and a clinical sample (n=134 youth; 44% male. Comparisons also used the Beck Depression Inventory (BDI-II and the Children's Depression Inventory (CDI. Results: The factor analysis revealed the unidimensionality of the measure. The KADS-6 demonstrated good internal consistency (Cronbach's alpha in both clinical (.74 and school (.80 samples. Its convergent validity with the BDI-II and CDI was r=.44; r=.61, respectively in the clinical sample and r=.60; r=.57 in the school sample. The KADS-6, a short and time efficient instrument, showed good psychometric characteristics in terms of internal consistency and convergent validity in comparison with the BDI-II and the CDI.

    Rheumatoid arthritis (RA) is significantly associated with psychiatric morbidity. Mental health conditions are often unrecognized and untreated in primary care. To assess prevalence of anxiety and depression and their impact on arthritis pain and functional disability in Slovak patients with rheumatoid arthritis. Anxiety was assessed by the Beck Anxiety Inventory (BAI), depression by the Zung self-rating depression scale (SDS), pain by the visual analog scale (VAS) and functional disability by the health assessment questionnaire - disability index (HAQ-DI) in 142 patients with rheumatoid arthritis. Spearman's rho was calculated to assess relations between variables. Stepwise linear regression analysis was used to assess impact of anxiety and depression on arthritis pain and functional disability. High prevalence of anxiety and depression was observed in arthritis patients. Anxiety and depression were significant predictors of arthritis pain and functional disability. Sex, education, marital status, disease duration and comorbidity had no impact on arthritis pain and functional disability. These findings support the notions that psychological negative affect can influence subjective perception of arthritis pain and disability. The regular screening of anxiety and depression and the psychological approaches can be useful for managing arthritis patients.

    Full Text Available Abstract Background Depressive and anxiety disorders often go unrecognized in distressed primary care patients, despite the overtly psychosocial nature of their demand for help. This is especially problematic in more severe disorders needing specific treatment (e.g. antidepressant pharmacotherapy or specialized cognitive behavioural therapy. The use of a screening tool to detect (more severe depressive and anxiety disorders may be useful not to overlook such disorders. We examined the accuracy with which the Four-Dimensional Symptom Questionnaire (4DSQ and the Hospital Anxiety and Depression Scale (HADS are able to detect (more severe depressive and anxiety disorders in distressed patients, and which cut-off points should be used. Methods Seventy general practitioners (GPs included 295 patients on sick leave due to psychological problems. They excluded patients with recognized depressive or anxiety disorders. Patients completed the 4DSQ and HADS. Standardized diagnoses of DSM-IV defined depressive and anxiety disorders were established with the Composite International Diagnostic Interview (CIDI. Receiver Operating Characteristic (ROC analyses were performed to obtain sensitivity and specificity values for a range of scores, and area under the curve (AUC values as a measure of diagnostic accuracy. Results With respect to the detection of any depressive or anxiety disorder (180 patients, 61%, the 4DSQ and HADS scales yielded comparable results with AUC values between 0.745 and 0.815. Also with respect to the detection of moderate or severe depressive disorder, the 4DSQ and HADS depression scales performed comparably (AUC 0.780 and 0.739, p 0.165. With respect to the detection of panic disorder, agoraphobia and social phobia, the 4DSQ anxiety scale performed significantly better than the HADS anxiety scale (AUC 0.852 versus 0.757, p 0.001.

    The study assesses the association between religiosity and coping style with the outcome of depression and diabetes. Using a simple random sampling, we recruited 112 participants with diabetes and an equal number with depression consecutively, matching for gender. Religiosity was determined using Religious Orientation Scale (revised) (ROS-R), coping styles with Brief Religious Coping (Brief RCOPE) scale and Mental Adjustment to Cancer (MAC) scale (adapted). Primary and secondary outcomes were evaluated using Sheehan's Disability Scale (SDS) and Becks Depression Inventory-II (BDI-II) respectively. Among participants with diabetes, BDI-II total scores correlated negatively with ROS-R Extrinsic Social (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.3, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.3, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). SDS global scores correlated positively with Helplessness/Hopelessness (r = 0.3, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). Among participants with depression, BDI-II total scores correlated negatively with Intrinsic religiosity (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.4, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.6, P < 0.05) and Brief RCOPE Negative (r = 0.7, P < 0.05). SDS global scores correlated negatively with Intrinsic religiosity (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.3, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.5, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05).

    The Hospital Anxiety and Depression Scale (HAD) have been used in Mexico in drug abusers, burned patients, older people, with renal insufficiency and high-risk pregnant women. The aim of this study was to determine reproducibility and accuracy of the questionnaire in a sample of obese subjects. A group of 75 obese patients (BMI > 27) without diabetes mellitus were invited to participated in the study. Diagnosis of anxiety or depression was made by an structured interview based on the DSM-IV criteria, and they were requested to complete the HAD. All subjects were randomized for the manoeuvre sequence. Sensibility specificity, positive predictive value and negative value, and unweighted kappa coefficient (for concordance) were calculated for the two procedures. The questionnaire reproducibility was assessed buy test-retest with other 25 independent subjects. Internal validity was estimated by alpha Cronbach, Guttman and intraclass correlation coefficients. Mean age was 39.7 +/- 11.5 years and BMI 39.1 +/- 9.6. The best cut off point for anxiety was 8 points (Kappa 0.68) and for depression 7 points (Kappa 0.73). Mean age for test-retest was 39.2 +/- 14.5 years and BMI 45.3 +/- 14.6. The alpha-Cronbach was 0.84 for the first tes. and 0.86 for the second. Intraclass coefficient correlation was 0.946. The HAD is applicable for obese subjects, it is reproducible and concordant with a structured interview.

    Objective To develop a depression screening scale for community elder. Methods An item pool consisted of 60 items was constructed through review, panel discussion and expert consultation. Item analysis was performed in a sample of 93 community-dwelling older people and 59 geriatric depression patients. Then the reliability and validity test of official screening scale was performed in 200 community elder people and 68 geriatric depression patients. Results The screening scale was consisted of 30 items and the incidence rate of each item in patients was higher than the community elder. The Cronbach’sαcoefficient was 0.98, and test-retest reliability after one week interval was 0.68(P<0.05).

    Full Text Available The Center of Epidemiologic Studies Depression Scale (CES-D is a commonly used self-report scale to measure depressive symptoms in the general population. In the present study, the Dutch version of the CES-D was administered to a sample of 837 Dutch-speaking adults of Belgium to examine the factor structure of the scale. Using confirmatory factory analysis (CFA, four first-order models and two second-order models were tested, and the second-order factor model with three pairs of correlated error terms provided the best fit to the data. Second, five socio-demographic variables (age, gender, education level, relation status, and family history of depression were included as covariates to the second-order factor model to explore the associations between background characteristics and the latent factor depression using a multiple indicators and multiple causes (MIMIC approach. Age had a significantly negative effect on depression, but the effect was not substantial. Female gender, lower education level, being single or widowed, and having a family history of depression were found to be significant predictors of higher levels of depression symptomatology. Finally, percentile norms on the CES-D raw scores were provided for subgroups of gender by education level for the general Dutch-speaking adult population of Belgium.

    In the present study, we investigated the association between the severity of each symptom evaluated by the Montgomery-Åsberg Depression Rating Scale (MADRS) at baseline and responsiveness to treatment in patients with major depressive disorder (MDD) to identify the items that predict treatment response. The patients received a diagnosis of MDD if they had a score greater than 20 points on the MADRS. Following admission, 120 patients were enrolled in the study, and 89 patients completed the study. For the first week, a 20-mg/d dose of paroxetine was administered; thereafter, the dose was increased to 40 mg/d. The MADRS was applied at baseline and after 1, 2, 4, and 6 weeks. We defined responders as patients with improvements in their MADRS scores of more than 50% after 6 weeks of treatment. A multiple regression analysis of MADRS scores at 6 weeks was performed to identify patients who responded to treatment. There was a significant difference between responders and nonresponders in the reported sadness (RS) score for all MADRS items. In the multiple logistic regression analysis, only the RS and concentration difficulties (C) scores showed a significant association with treatment response. Based on the results of χ tests, RS score cutoff values of 2/3 and 3/4 revealed significant differences in the responder rate. None of the cutoff values for the C score revealed significant differences. The RS score was significantly associated with responsiveness to paroxetine treatment for MDD, with higher RS scores predicting poor responses to treatment.

    Objectives: Antidepressants are the first line treatment for moderate to severe major depressive disorder (MDD) in perinatal and general populations. However, there appears to be paucity of evidence around antidepressant use in women with postpartum depression or anxiety. Selection of an appropriate antidepressant is crucial in promoting efficacy, optimizing tolerability, and managing comorbid anxiety or depression. Our aim was to investigate the treatment effect and tolerability profile of desvenlafaxine, and to examine the functionality of women with postpartum depression or anxiety after desvenlafaxine treatment. Methods: Fifteen postpartum women with depression or anxiety completed this 12-week prospective pilot study with a flexible dose of desvenlafaxine (50–100 mg). Participants were recruited at a tertiary care level program. Measures of depression (Montgomery–Åsberg Depression Rating Scale, MADRS), anxiety (Hamilton Anxiety Rating Scale, HAM-A), worry (Penn State Worry Questionnaire, PSWQ) and functional impairment (Sheehan Disability Scale, SDS) were completed at baseline, 8 weeks, and 12 weeks. Results: In the intention-to-treat analysis (n = 17), the majority of women responded to medication (88.2%, n = 15), and reached remission of depressive (82.4%, n = 14) and anxiety symptoms (82.4%, n = 14). Remission of depression was achieved in a mean of 6.9 weeks [standard deviation (SD) = 3.01] at a mean dose of 71 mg/day (SD = 25.7). Significant decreases were observed on PSWQ worry scores (p < 0.0001) and SDS scores for social (p < 0.0001) and family life impairment (p < 0.0001). The medication was generally well tolerated. Conclusion: The results of our prospective pilot study suggest that treatment with desvenlafaxine of postpartum mothers with depression or anxiety can lead to symptom remission and restoration of functionality.

    The eight-item Athens Insomnia Scale (AIS-8) is an instrument that has been used frequently to assess insomnia problems. Previous research on adults has found that the AIS-8 functioned as a sole component. This study aimed to examine the prevalence rates of insomnia problems on the AIS-8, the factor structure of the AIS-8 in adolescents and its associations with demographic characteristics and depression in adolescents. A total of 8319 adolescent students (4334 girls and 3985 boys, mean age = 14.7 years, standard deviation = 1.7 years) in southern Taiwan were recruited into this study and completed the AIS-8. We performed an exploratory factor analysis to examine the factor structure of the AIS-8, and used the parallel analysis for making decisions regarding factor retention. We also used multiple regression analysis models to determine the associations between insomnia and demographic characteristics and depression. The results found that a high proportion of adolescents had insomnia problems as measured by the AIS-8. The AIS-8 was composed of two different factors when used among a large adolescent population, including insomnia symptoms (factor 1) and subjective sleep and daytime distress (factor 2). While being male, being younger, and having depression were associated positively with the severity of insomnia symptoms (factor 1), being older, living in urban areas, and having depression were associated positively with the severity of subjective sleep and daytime distress (factor 2). Clinicians and researchers should consider the different meanings of the two factors of the AIS-8 when using this tool to assess insomnia problems in adolescents.

    In the present study, a novel method was used for entrapping the protein, insulin into the catanionic SDS/CTAB vesicle membrane. The anionic SDS and cationic CTAB formed catanionic vesicles at particular concentration (35:65 by volume). In this study, vesicle membrane can be considered as model membrane. The vesicle formation and entrapment efficiency depend on the pH of the aqueous solution. The insulin molecules have attached with the vesicular membrane at pH 7.0. However, at acidic pH, the vesicles were ruptured and the insulin did not entrap into the vesicle membrane, whereas at alkaline pH insulin became fibriller. The scanning electron microscope (SEM), Dynamic light scattering (DLS), and Zeta potential studies established the self-assembled structure formation of insulin and catanionic vesicles. To know the protein confirmations, Circular dichroism (CD) was also employed. The temperature dependent steady state and time resolved emission spectroscopy show that at room temperature (25 °C), apart from the 305 nm tyrosine fluorescence, a new emission peak at 450 nm was observed only in case of insulin-vesicle system, and was assigned as the tyrosine phosphorescence. This phosphorescence peak is the signature of the entrapment of insulin into the vesicle membrane. Highlights: • SDS-CTAB based catanionic vesicle has been fabricated. • Insulin has been successfully immobilized on these vesicles. • Immobilized insulin shows room temperature phosphorescence.

    The aim of this retrospective study was to characterise intrapartum and neonatal outcomes in women with an antenatally recorded Edinburgh Postnatal Depression Score (EPDS) ≤ 9 compared with women with a score of ≥12 at a major Australian tertiary maternity hospital. Women with scores ≥12 are at particularly high risk of major depressive symptomatology. There were 20512 (78.6%) women with a score ≤ 9 and 2708 (10.4%) had a score ≥ 12. Category 1 caesarean sections where there was immediate threat to life (maternal or fetal) were more common in women with EPDS scores ≥12 (5.2% vs. 4.3%, OR 1.24 95% CI 1.03–1.49, p = 0.024). Pre-term birth (birth weights birth (34.4% vs. 30.6%, p < 0.001) and neonatal death (0.48% vs. 0.13%, OR 2.52 95% CI 1.2–5.0, p < 0.001) were higher in babies of these women. These results suggest poorer intrapartum and neonatal outcomes for women with high EPDS scores. PMID:27658526

    The objective of the fire accident analysis for the compartment where the ITER tritium storage and delivery system (hereafter SDS) glove boxes are installed is to estimate the integrity of the glove box. Fires in grouped electrical cable trays pose distinct fire hazards within the compartment where the SDS glove boxes are installed. The nuclear industry has defined two general types of electrical cables, referred to as IEEE 383 qualified and unqualified. According to NUREG/CR 4679 and DOT TSC UMAT 83 4 1, a damage threshold temperature of 370 .deg. C and a critical heat flux of 10 kW/m2 have been selected for IEEE 383 qualified cable. A damage threshold temperature of 218 .deg. C and a critical heat flux of 5 kW/m2 have been selected for IEEE 383 unqualified cable. Cable tray fires can occur from various sources. The scenarios of concern include a fire within a cable tray and as exposure fire. However, fire within the compartment where the SDS glove boxes are installed could be happened due to over currents. Therefore, it is common practice to consider only self ignited cable fires to occur in power cable trays since they carry enough electrical energy for ignition. In general, electrical cables typically do not carry enough electrical energy for self ignition. According to NUREG/CR 5384, it was concluded that electrical cables which passed the IEEE 383 74 flame test were less likely to propagate electrically initiated fires. However, the scenario in this fire accident analysis assumed that the IEEE 383 qualified cable is burned completely.

    Full Text Available Background and objectives: Sodium Dodecyl Sulfate (SDS is one of the most widely used anionic detergents. The present study deals with isolation and identification of SDS-degrading bacteria from a detergent contaminated pond situated in Varanasi city, India."nMaterials and Methods: Employing enrichment technique in minimal medium (PBM, SDS-degrading bacteria were isolated from pond water sample. Rate of degradation of SDS was studied in liquid PBM and also degradation of different concentrations of SDS was also studied to find out maximum concentration of SDS degraded by the potent isolates. Alkyl sulfatase activity (key enzyme in SDS degradation was estimated in crude cell extracts and multiplicity of alkyl sulfatase was studied by Native PAGE Zymography. The potent isolate was identified by 16S rRNA sequence analysis."nResults: Using enrichment technique in minimal medium containing SDS as a sole carbon source, initially three SDS degrading isolates were recovered. However, only one isolate, SP3, was found to be an efficient degrader of SDS. It was observed that this strain could completely metabolize 0.1% SDS in 16 h, 0.2% SDS in 20 h and 0.3% SDS in 24 h of incubation. Specific activity of alkyl sulfatase was 0.087±0.004 μmol SDS/mg protein/min and Native PAGE Zymography showed presence of alkyl sulfatase of Rf value of 0.21. This isolate was identified as Pseudomonas putida strain SP3."nConclusion: This is the report of isolation of SDS-degrading strain of P. putida, which shows high rate of SDS degradation and can degrade up to 0.3% SDS. It appears that this isolate can be exploited for bioremediation of this detergent from water systems.

  6. Problems in cross-cultural use of the hospital anxiety and depression scale: "no butterflies in the desert".

    Directory of Open Access Journals (Sweden)

    Gemma A Maters

    Full Text Available OBJECTIVE: The Hospital Anxiety and Depression Scale (HADS is widely used to screen for anxiety and depression. A large literature is citable in support of its validity, but difficulties are increasingly being identified, such as inexplicably discrepant optimal cutpoints and inconsistent factor-structures. This article examines whether these problems could be due to the construction of the HADS that poses difficulties for translation and cross-cultural use. METHODS: Authors' awareness of difficulties translating the HADS were identified by examining 20% of studies using the HADS, obtained by a systematic literature search in Pubmed and PsycINFO in May 2012. Reports of use of translations and validation studies were recorded for papers from non-English speaking countries. Narrative and systematic reviews were examined for how authors dealt with different translations. RESULTS: Of 417 papers from non-English speaking countries, only 45% indicated whether a translation was used. Studies validating translations were cited in 54%. Seventeen reviews, incorporating data from diverse translated versions, were examined. Only seven mentioned issues of language and culture, and none indicated insurmountable problems in integrating results from different translations. CONCLUSION: Initial decisions concerning item content and response options likely leave the HADS difficult to translate, but we failed to find an acknowledgment of problems in articles involving its translation and cross-cultural use. Investigators' lack of awareness of these issues can lead to anomalous results and difficulties in interpretation and integration of these results. Reviews tend to overlook these issues and most reviews indiscriminately integrate results from studies performed in different countries. Cross-culturally valid, but literally translated versions of the HADS may not be attainable, and specific cutpoints may not be valid across cultures and language. Claims about rates

    Full Text Available Abstract Background Interpretation of the Hospital Anxiety and Depression Scale (HADS, commonly used to assess anxiety and depression in COPD patients, is unclear. Since its minimal important difference has never been established, our aim was to determine it using several approaches. Methods 88 COPD patients with FEV1 ≤ 50% predicted completed the HADS and other patient-important outcome measures before and after an inpatient respiratory rehabilitation. For the anchor-based approach we determined the correlation between the HADS and the anchors that have an established minimal important difference (Chronic Respiratory Questionnaire [CRQ] and Feeling Thermometer. If correlations were ≥ 0.5 we performed linear regression analyses to predict the minimal important difference from the anchors. As distribution-based approach we used the Effect Size approach. Results Based on CRQ emotional function and mastery domain as well as on total scores, the minimal important difference was 1.41 (95% CI 1.18–1.63 and 1.57 (1.37–1.76 for the HADS anxiety score and 1.68 (1.48–1.87 and 1.60 (1.38–1.82 for the HADS total score. Correlations of the HADS depression score and CRQ domain and Feeling Thermometer scores were Conclusion The minimal important difference of the HADS is around 1.5 in COPD patients corresponding to a change from baseline of around 20%. It can be used for the planning and interpretation of trials.

    Permeability of dialysis membranes for high molecular weight compounds should be similar to that of the glomerular membrane in order to remove uremic toxins like the human kidney does. In order to evaluate permeability of high-flux dialysis membranes SDS-PAGE is applied for examination of filtrate of dialysers during routine dialysis with different membranes. SDS-PAGE analysis is performed with silver staining method according to the modification of Melzer (5) and consecutive laser densitometry. The protein pattern of filtrate from dialysis membranes is similar to that of the glomerular membrane containing IgG, transferrin, albumin, alpha-1-microglobulin, retinol binding protein and beta-2-microglobulin. Comparing different membranes there are considerable differences depending on cut-off, charge and adsorption capacity of the particular membrane. In all membranes tested permeability of proteins decreases during one treatment session. Protein permeability of high-flux dialysis membranes is similar to the gloemerular membrane but modified according to pore-size, surface charge, adsorption and time on dialysis. In contrast to the glomerular membrane in each of the investigated membranes protein permeability decreases during function.

    The inter-rater reliability of the French versions of the MADRS and the DRRS was studied on the basis of 58 videotape records of structured standardised interviews of depressed inpatients under antidepressant treatment. Each patient was assessed by two trained raters, from the same videotape recording. The inter-rater reliability of total scores was high with both scales (intra-class correlation coefficients: 0.86 for MADRS and 0.77 for DRRS). However, the inter-rater reliability for individual items was higher and more homogeneous for the MADRS than for the DRRS. Finally, the structured interview in French appears to be relevant for the MADRS, but it should be improved for the DRRS.

    A wide range of questionnaires for measuring depression are available. Item Response Theory models can help to evaluate the questionnaires exceeding the boundaries of Classical Test Theory and provide an opportunity to equate the questionnaires. In this study after checking for unidimensionality, a General Partial Credit Model was applied to data from two different depression scales [Patient Health Questionnaire (PHQ-9) and ICD-10-Symptom Rating (ISR)] obtained in clinical settings from a consecutive sample, including 4517 observations from a total of 2999 inpatients and outpatients of a psychosomatic clinic. The precision of each questionnaire was compared and the model was used to transform scores based on the assumed underlying latent trait. Both instruments were constructed to measure the same construct and their estimates of depression severity are highly correlated. Our analysis showed that the predicted scores provided by the conversion tables are similar to the observed scores in a validation sample. The PHQ-9 and ISR depression scales measure depression severity across a broad range with similar precision. While the PHQ-9 shows advantages in measuring low or high depression severity, the ISR is more parsimonious and also suitable for clinical purposes. Furthermore, the equation tables derived in this study enhance the comparability of studies using either one of the instruments, but due to substantial statistical spread the comparison of individual scores is imprecise.

Patients and methods: A cross-sectional study was conducted of 84 elderly residents (46 women, 38 men, age range 60–94 years in a long-term residential home setting in Thailand between March and June 2011. The selected residents went through a comprehensive geriatric assessment that included use of the Mini-Mental State Examination, Mini-International Neuropsychiatric Interview, and CSDD instruments. Intraclass correlation (ICC was calculated in order to establish the level of agreement between the residents and caregivers, in light of the residents' cognitive status. Confirmatory factor analysis (CFA was adopted to evaluate the alternative CSDD models. Results: The CSDD yielded a high internal consistency (Cronbach's alpha = 0.87 and moderate agreement between residents and caregivers (ICC = 0.55; however, it was stronger in cognitively impaired subjects (ICC = 0.71. CFA revealed that there was no difference between the four-factor model, in which factors A (mood-related signs and E (ideational disturbance were collapsed into a single factor, and the five-factor model as per the original theoretical construct. Both models were found to be similar, and displayed a poor fit. Conclusion: The CSDD demonstrated a moderate level of interrater agreement between residents and caregivers, and was more reliable when used with cognitively impaired residents. CFA indicated a poorly fitting model in this sample. Keywords: Cornell Scale for Depression in Dementia (CSDD, factor structure

    Full Text Available Abstract Background The aim of this study was to test the internal validity of the total Center for Epidemiologic Studies-Depression (CES-D scale using Rasch analysis in a rheumatoid arthritis (RA population. Methods CES-D was administered to 157 patients with RA over three time points within a 12 month period. Rasch analysis was applied using RUMM2020 software to assess the overall fit of the model, the response scale used, individual item fit, differential item functioning (DIF and person separation. Results Pooled data across three time points was shown to fit the Rasch model with removal of seven items from the original 20-item CES-D scale. It was necessary to rescore the response format from four to three categories in order to improve the scale's fit. Two items demonstrated some DIF for age and gender but were retained within the 13-item CES-D scale. A new cut point for depression score of 9 was found to correspond to the original cut point score of 16 in the full CES-D scale. Conclusion This Rasch analysis of the CES-D in a longstanding RA cohort resulted in the construction of a modified 13-item scale with good internal validity. Further validation of the modified scale is recommended particularly in relation to the new cut point for depression.

    To investigate and analyze the status of anxiety and depression among patients with four types of peripheral vertigo. The clinical data of patients with one of the four types of peripheral vertigo, namely benign paroxysmal positional vertigo (BPPV), vestibular migraine (VM), Menière's disease (MD), and vestibular neuritis (VN), were collected. Thorough otological and neuro-otological examinations were performed on these patients, and their status of anxiety and depression were assessed using self-rating anxiety scale (SAS) and self-rating depression scale (SDS). A total of 129 patients with one of the four types of peripheral vertigo(49 cases of BPPV, 37 cases of VM, 28 cases of MD and 15 cases of VN) were included in the study. The scores of SAS and SDS were higher in the patients with VM or MD than those with BPPV or VN (P vertigo, anxiety/depression is more common in patients with VM or MD. This may be due to the different mechanisms involved in different types of vertigo, as well as differences in the prevention and self-control of the patients against the vertigo.

Mild and moderate PD patients (n=46 were evaluated for depression according to the DSM IV criteria. All patients were assessed with the MADRS and the BDI. A "receiver operating characteristics" (ROC curve was obtained and the sensibility, specificity, positive and the negative predictive values were calculated for different cut-off scores of the MADRS and the BDI. The Kappa statistic was calculated for different cut-off scores to assess the agreement between the clinical judgment and both scales. Depression was present in 18 patients. MADRS cut-off scores of 6 and 10 showed Kappa 0.5 and 0.56, respectively. Specificity of cut-off score of 6 was 78.6% and of cut-off score of 10 was 96.4%. Kappa agreement of BDI cut-off scores of 10 and 18 were 0.36 and 0.62, respectively. Specificity was 60.7% for 10 and 92.9% for 18. Both rating scales show similar accuracy within the ROC curves (84.3% for MADRS and 79.7% for BDI. The MADRS and the BDI show a good accuracy and correlation to the clinical diagnosis when a cut-off score of 10 is used to MADRS and a cut-off score of 18 is used to BDI to recognize depression in mild to moderate PD patients.

    Full Text Available Studies have found that people with Multiple Sclerosis experience relatively high rates of anxiety and depression. Although methodologically robust, many of these studies had access to only modest sample sizes (N4000 to: describe the depression and anxiety profiles of people with MS; to determine if anxiety and depression are related to age or disease duration; and to assess whether the levels of anxiety and depression differ between genders and types of MS.From its launch in May 2011 to the end of December 2011, 7786 adults with MS enrolled to take part in the UK MS Register via the web portal. The responses to the Hospital Anxiety and Depression Scale (HADS were collated with basic demographic and descriptive MS data provided at registration and the resulting dataset was analysed in SPSS (v.16.The mean HADS score among the 4178 respondents was 15.7 (SE 0.117, SD 7.55 with a median of 15.0 (IQR 11. Anxiety and depression rates were notably high, with over half (54.1% scoring ≥ 8 for anxiety and 46.9% scoring ≥ 8 for depression. Women with relapsing-remitting MS were more anxious than men with this type (p<0.001, and than women with other types of MS (p = 0.017. Within each gender, men and women with secondary progressive MS were more depressed than men or women with other types of MS (p<0.001, p<0.001.This largest known study of its kind has shown that anxiety and depression are highly prevalent in people with MS, indicating that their mental health needs could be better addressed. These findings support service planning and further research to provide the best care for people with MS to help alleviate these debilitating conditions.

    Health care professionals are coming under increased pressure to empirically monitor patient outcomes across settings as a means of improving clinical practice. Within the psychiatric and primary care communities, many have begun utilizing brief psychometric measures of psychological functioning to accomplish these goals. The purpose of this study was to evaluate the psychometric properties and clinical utility of the Depression, Anxiety, and Stress Scales-21-item version (DASS-21), and contribute normative data to facilitate interpretation using a sample of U.S. adults (N = 503). Item-scale convergence was generally supported, although assumptions of item-scale divergence were not met. Only 86%, 50%, and 43% of Depression, Anxiety, and Stress items, respectively, correlated significantly greater with their hypothesized scales than other scales. Internal consistency reliability was acceptable for all scales and comparable to existing research (αs = .91, .80, and .84 for Depression, Anxiety, and Stress, respectively). Scale-level correlations were greater than what has been reported elsewhere (range of rs = .68 to .73), and principal components analysis supported the extraction of only one component accounting for 47% of the item-level variance. However, confirmatory factor analysis (CFA) favored a three-factor structure when compared to a one-factor model. The implications for the health care professions are discussed.

    It is proposed that large-scale impact craters provide boundary conditions for the thermal and rheological history of Ganymede. On Ganymede as in the case of the moon, the ratio of the depth to the radius of the impact crater is about 1/5. Models of the heat flow from Ganymede suggest that the most realistic depths h for Gilgamesh and Hathor are 29 and 12 km, respectively.

    Full Text Available Negative affect (NA plays a significant role in the initiation, persistence, and response to psychotherapy of many client problems (Moses & Barlow, 2006. This report describes the development of a brief NA measure, the Depression/Anxiety Negative Affect (DANA scale, and preliminary analyses of its psychometric properties. An initial pool of DANA items was selected on the basis of a review of relevant literature about emotion science and counseling outcomes, related tests, and feedback from psychotherapists as part of a pilot test. The DANA was evaluated in two representative clinical samples where psychotherapists produced a total of 363 session ratings with 81 clients. DANA scores evidenced adequate internal consistency, evidence of convergent and discriminant validity, and sensitivity to change over the course of psychotherapy. Effect sizes (ES of DANA scores consistently equaled or exceeded the average ES of .68 found for scales assessing the outcomes of counseling and psychotherapy in meta-analytic studies (Smith & Glass, 1977. ESs greater than 1 were found on DANA variables for clients whose therapists rated them as experiencing, rather than avoiding, NA.

    A decrease in the level of engagement in activities ("behavioral activation") is usually observed in major depressive disorder. Because behavioral treatments of depression aim to counteract that mechanism, assessing changes in behavioral activation during treatment is of great interest. Therefore, Manos et al. (2011) developed a scale that assesses these changes, which was called the Behavioral Activation for Depression Scale-Short Form (BADS-SF). The aim of this study is to present a French version of this scale and to discuss its psychometric properties. The BADS-SF was translated into French, and 504 non-clinical adults completed an online survey that was composed of that scale and convergent measures. Exploratory and confirmatory factor analyses were performed in two independent samples, and a two-factor solution was recommended, which references two functions of the engagement in activities (i.e., "activation" and "avoidance"). The results showed high levels of internal consistency and satisfying scores in terms of skewness and kurtosis. Moreover, relationships with measures of depression and behavioral systems indicated a good convergent validity. Therefore, the French BADS-SF can be seen as a reliable and valid instrument.

In the current study, we examined the associations of SES with dietary intake of folate and health outcomes in general Japanese workers. This Japanese occupational cohort consisted off 2266 workers. SES was assessed by a self-administered questionnaire. Intakes of all nutrients were assessed with a validated, brief and self-administered diet history questionnaire (BDHQ. The degree of depressive symptoms was measured by the validated Japanese version of the K6 scale. Multiple linear regression and stratified analysis were used to evaluate the associations of intake with the confounding factors. Path analysis was conducted to describe the impacts of intake on health outcomes. Education levels and household incomes were significantly associated with intake of folate and depression scales (p < 0.05. After adjusting for age, sex and total energy intake, years of education significantly affect the folate intake (β = 0.117, p < 0.001. The structural equation model (SEM shows that the indirect effect of folate intake is statistically significant and strong (p < 0.05, 56% of direct effect in the pathway of education level to depression scale. Our study shows both education and income are significantly associated with depression scales in Japanese workers, and the effort to increase the folate intake may alleviate the harms of social disparities on mental health.

    The objective of the study was to evaluate the psychometric properties of the Edinburg Postnatal Depression Scale (EPDS) to detect depression during pregnancy in Chile. The EPDS was applied to a sample of 111 pregnant women, who were attending an antenatal appointment in primary care centers. The Beck Depression Inventory (BDI-I) was used to assess the convergent validity, and the Depressive Episode module of the MINI was used to identify cases. The factor analysis showed that there was a good fit, with a factor model that explains 57.6 % of the total variance. There was a high degree of internal consistency (Cronbach's α = 0.914) and good convergent validity with the BDI-I (rho = 0.850, p < 0.001). The EPDS was capable of differentiating cases of depression from non-cases. The best cutoff point was between 12 and 13, corresponding to an overall accuracy of 87.4 %. The questionnaire has good psychometric properties and can be useful for detecting cases of depression during pregnancy.

    Depression is a common comorbidity in people with HIV/AIDS, frequently impacting disease status by direct effects on immune fuinction and adherence to antiretroviral treatment. For case managers, who are often the main contacts for patients, quick and simple identification of patients at high risk for depression can be both a challenge and a priority. These patients should be screened at the primary point of care and then referred to mental health providers for further evaluation or diagnosis. Here we report the experiences in three diverse case management settings using the Zung Self-Rating Depression Scale for patient self-reporting of depression symptoms. The three clinics--Broward House in Wilton Manors, Florida; BIENESTAR Human Services in Los Angeles, California, and the West Midtown Medical Group in New York City--serve diverse racial and ethnic populations with substantial HIV infection rates in urban and rural communities. Benefits of using this validated tool include increased patient self-awareness and acceptance by mental health providers, thereby facilitating a final diagnosis that leads to improved implementation of treatment for depression. Case management settings provide a unique point of contact to unite clients with mental health care, especially in disease settings where depression or other mental health conditions are prevalent.

    Full Text Available Abstract Background Depression is a common co-morbid health problem in patients with diabetes that is underrecognised. Current international guidelines recommend screening for depression in patients with diabetes. Yet, few depression screening instruments have been validated for use in this particular group of patients. Aim of the present study was to investigate the psychometric properties of the Turkish version of the Centre for Epidemiologic Studies Depression Scale (CES-D in patients with type 2 diabetes. Methods A sample of 151 Turkish outpatients with type 2 diabetes completed the CES-D, the World Health Organization-Five Well-Being Index (WHO-5, and the Problem Areas in Diabetes scale (PAID. Explanatory factor analyses, various correlations and Cronbach's alpha were investigated to test the validity and reliability of the CES-D in Turkish diabetes outpatients. Results The original four-factor structure proposed by Radloff was not confirmed. Explanatory factor analyses revealed a two-factor structure representing two subscales: (1 depressed mood combined with somatic symptoms of depression and (2 positive affect. However, one item showed insufficient factor loadings. Cronbach's alpha of the total score was high (0.88, as were split-half coefficients (0.77-0.90. The correlation of the CES-D with the WHO-5 was the strongest (r = -0.70, and supported concurrent validity. Conclusion The CES-D appears to be a valid measure for the assessment of depression in Turkish diabetes patients. Future studies should investigate its sensitivity and specificity as well as test-retest reliability.

    This is the first study to assess the efficacy of desvenlafaxine (administered as desvenlafaxine succinate) for improving depressive symptoms and functioning exclusively in employed patients with major depressive disorder (MDD). Gainfully employed (≥20 h/wk) male and female outpatients with MDD were randomly assigned (2:1 ratio) to 12 weeks of double-blind treatment with desvenlafaxine 50 mg/d or placebo. Analysis of covariance was used to compare differences in week 12 adjusted mean changes from baseline on the 17-item Hamilton Depression Rating Scale (HAM-D₁₇) (primary outcome) and Sheehan Disability Scale (SDS) (key secondary outcome) in the intent-to-treat (ITT) population. A predefined, modified ITT population (ie, those in the ITT population with baseline HAM-D₁₇ ≥20) was also analyzed. Tolerability was assessed by recording adverse events and change on the Arizona Sexual Experience Scale. Baseline HAM-D₁₇ scores for desvenlafaxine (n = 285) and placebo (n = 142) were 22.0 and 21.8, whereas baseline SDS scores were 19.8 and 20.4. Adjusted mean differences between desvenlafaxine and placebo were 2.1 (95% confidence interval [CI], 0.78-3.46; P = 0.002) on the HAM-D₁₇ and 1.3 (95% CI, -0.09 to 2.76; P = 0.067) on the SDS. For the modified ITT sample, desvenlafaxine (n = 208) and placebo (n = 102), baseline HAM-D₁₇ scores were 23.8 and 23.9; the SDS baseline scores were 20.1 and 20.8. Mean differences were 2.6 (95% CI, 0.93-4.22; P = 0.002) on the HAM-D₁₇ and 2.1 (95% CI, 0.36-3.76; P = 0.017) on the SDS. Adverse events and Arizona Sexual Experience Scale scores were comparable between groups. Desvenlafaxine 50 mg/d was efficacious for treating MDD in gainfully employed adults. Between-group differences on the SDS narrowly missed statistical significance in the ITT population alone, but the totality of data suggests functional improvements with active treatment.

  11. Use of the soil and water assessment tool to scale sediment delivery from field to watershed in an agricultural landscape with topographic depressions.

    2014-01-01

    For two watersheds in the northern Midwest United States, we show that landscape depressions have a significant impact on watershed hydrology and sediment yields and that the Soil and Water Assessment Tool (SWAT) has appropriate features to simulate these depressions. In our SWAT models of the Willow River in Wisconsin and the Sunrise River in Minnesota, we used Pond and Wetland features to capture runoff from about 40% of the area in each watershed. These depressions trapped considerable sediment, yet further reductions in sediment yield were required for calibration and achieved by reducing the Universal Soil Loss Equation (USLE) cropping-practice (P) factor to 0.40 to 0.45. We suggest terminology to describe annual sediment yields at different conceptual spatial scales and show how SWAT output can be partitioned to extract data at each of these scales. These scales range from plot-scale yields calculated with the USLE to watershed-scale yields measured at the outlet. Intermediate scales include field, upland, pre-riverine, and riverine scales, in descending order along the conceptual flow path from plot to outlet. Sediment delivery ratios, when defined as watershed-scale yields as a percentage of plot-scale yields, ranged from 1% for the Willow watershed (717 km) to 7% for the Sunrise watershed (991 km). Sediment delivery ratios calculated from published relations based on watershed area alone were about 5 to 6%, closer to pre-riverine-scale yields in our watersheds.

The instruments used were the Zung Depression Self-Rating Scale (SDS, Life Regard Index (LRI, the Neuroticism scale by Eysenck (EPQ-N, the Tension and Effort Stress Inventory (TESI, the Subjective Health Complaints scale (SHC, and the Sense of Humour Questionnaire (SHQ-6. Results: Analyzes of Variance showed sex and urban/rural main effects, and/or interactions (boys and rural students showing highest positive ratings. Stepwise regression analyzes on depression showed all but the TESI variables to significantly explain 41% of the variance in depression. The Sense of Humour and Life Regard Index were strong contributors to depression (55% of variation when effects of bodily complaints and scores on stressors and efforts were eliminated. Conclusions: The present study showed an unexpectedly high prevalence of severe (12.7% as well as moderate depressive symptoms (total of 49.2%. Therefore, the results indicate an increase of adolescent depression in recent years. Negative and positive mood, as well as sense of humour, goals in life, and fulfilment of goals seemed to be protecting. Prevalence of depressive symptoms in adolescents was shown to be higher than expected. Positive resource variables appeared to be protecting.

    Full Text Available Abstract Background Recently, we reported a unique approach to preserve the activity of some proteins in the presence of the denaturing agent, Sodium Dodecyl Sulfate (SDS. This was made possible by addition of the amphipathic solvent 2,4-Methyl-2-PentaneDiol (MPD, used as protecting but also as refolding agent for these proteins. Although the persistence of the protein activity in the SDS/MPD mixture was clearly established, preservation of their structure was only speculative until now. Results In this paper, a detailed X-ray study addresses the pending question. Crystals of hen egg-white lysozyme were grown for the first time in the presence of MPD and denaturing concentrations of SDS. Depending on crystallization conditions, tetragonal crystals in complex with either SDS or MPD were collected. The conformation of both structures was very similar to the native lysozyme and the obtained complexes of SDS-lysozyme and MPD-lysozyme give some insights in the interplay of protein-SDS and protein-MPD interactions. Conclusion This study clearly established the preservation of the enzyme structure in a SDS/MPD mixture. It is hypothesized that high concentrations of MPD would change the properties of SDS and lower or avoid interactions between the denaturant and the protein. These structural data therefore support the hypothesis that MPD avoids disruption of the enzyme structure by SDS and can protect proteins from SDS denaturation.

    Depressive symptoms have become the most important global public health issue. Iron plays an important role in brain function, cognition, and behavior, and its impacts on depressive symptoms may be multifactorial with both positive and negative effects. Previous observational studies focusing on the association between iron status and depressive symptoms showed inconsistent results. Ferritin is a ubiquitous intracellular protein that can store and release iron and is widely used as a clinical biomarker to evaluate iron status. We performed a cross-sectional study to examine the relationship between serum ferritin and depressive symptoms among 3,839 subjects who were from the Tianjin Chronic Low-grade Systemic Inflammation and Health (TCLSIHealth) cohort. Depressive symptoms were assessed using the Chinese version of 20-item self-rating Depression Scale (SDS) with 4 cutoffs (40, 45, 48 and 50) to indicate elevated depressive symptoms (40 was the primary cut-off). The prevalence of depressive symptoms was 36.5%, 17.6%, 11.0% and 7.0% for SDS ≥40, ≥45, ≥48 and ≥50, respectively. With the primary cut-off point of 40, multiple potential confounding factors were adjusted and the odds ratios (95% confidence interval) of having elevated depressive symptoms by quartiles of serum ferritin concentrations were 1.00 (reference), 1.10 (0.91, 1.34), 0.81 (0.66, 1.01) and 1.02 (0.81, 1.28) for the first, second, third and fourth quartile, respectively (P for trend = 0.76). Similar relations were observed with the use of other cut-offs as a definition of depressive symptoms. In conclusion, there is no significant relationship between serum ferritin concentrations and depressive symptoms among Chinese adults.

    Although a body of research has targeted predictors of well-being and depression in old age, the consideration of oral health-related quality of life (OHRQoL) as a predictor of these major psychosocial endpoints has been rare in the previous literature. The objective of this study was to test whether OHRQoL is associated with well-being and depression, after controlling for relevant confounders; also, the mediating role of subjective health, a major predictor of both well-being and depression, has been explored. OHRQoL was measured by two commonly used assessment instruments, the geriatric oral health assessment index (GOHAI) and oral health impact profile (OHIP); well-being was assessed by the Philadelphia Geriatric Center Morale Scale (PGCMS) and depression by the self-rating depression scale (SDS). We used a subsample of 197 participants from the older cohort (1930-1932) of the Interdisciplinary Longitudinal Study of Adult Development. Regression models and structural equations modeling (SEM) were used for the test for study variable relationships. Both GOHAI and OHIP revealed significant associations to both PGCMS and SDS at the bivariate level. In regression analyses considering gender, household situation, subjective health, and both OHRQoL indicators, only OHIP remained a significant predictor of well-being and depression. In addition, supportive evidence for a mediating role of subjective health regarding the linkage between OHRQoL and an overall latent construct of well-being was found in the SEM analysis. In conclusion, OHRQoL is significantly linked with well-being and depression in old age, while subjective health is able to mediate the relationship. The generally underrated role of OHRQoL with respect to well-being and depression in late adulthood deserves more attention.

    We present a method of incorporation of gold nanoparticles in SDS (sodium dodecyl sulfate) bubbles with a low polydispersity index (monodispersed nanoparticles). Both the bubbles and nanoparticles maintained their structural and morphologic properties after functionalization. The bubbles present a radio of 0.38 mm with a standard deviation of±0.018 mm. The gold nanoparticles were obtained with sucrose as the catalytic agent and ascorbic acid as the reducing agent. The nanoparticles display several geometric morphologies as well as sizes inferior to 50 nm, as observed in the images obtained with Transmission Electron Microscopy (TEM). The optical properties were studied by optical absorption spectroscopy. The absorption band linked to the surface plasmon resonance (SPR) is located at 550 nm before and after the functionalization of the bubbles. Moreover, microscopic bubbles with a diameter smaller than 1 μm with the ability to stabilize nanoparticles in their surface were found in isolated regions of the sample. Additionally, the Surface Enhancement Raman Spectroscopy (SERS) properties of the colloid were analyzed with common drugs.

    Cortical spreading depression (CSD) is the electrophysiological correlate of migraine aura. Transgenic mice carrying the R192Q missense mutation in the Cacna1a gene, which in patients causes familial hemiplegic migraine type 1 (FHM1), exhibit increased propensity to CSD. Herein, mass spectrometry imaging (MSI) was applied for the first time to an animal cohort of transgenic and wild type mice to study the biomolecular changes following CSD in the brain. Ninety-six coronal brain sections from 32 mice were analyzed by MALDI-MSI. All MSI datasets were registered to the Allen Brain Atlas reference atlas of the mouse brain so that the molecular signatures of distinct brain regions could be compared. A number of metabolites and peptides showed substantial changes in the brain associated with CSD. Among those, different mass spectral features showed significant ( t-test, P migraine pathophysiology. The results also demonstrate the utility of aligning MSI datasets to a common reference atlas for large-scale MSI investigations.

    Purpose: To compare the effect of 20 cm SDS-PAGE electrophoresis, which is most widely used in proteomic research, in identifying human lens epithelium B3 (HLE B3) cells plasma membrane calcium ATPase (PMCA) isoform's apparent molecular weight (MW), with that of 8 cm SDS-PAGE electrophoresis.Method: HLE B-3 cells were cultured and membrane protein sample was collected. Part of the sample is electrophoresised with 20 cm gel, 16 mA/gel for 1.5 hrs and then 24 mA/gel for 4~5 hrs. The same sample is electrophoresised with 8cm mini gel, 200V for 2 hrs. Protein marker of known MW was run with the sample in the same gel. The resulting separated proteins were transferred to polyvinylidene difluoride (PVDF) membrane and Western blot were used to identify the PMCA isoform with specific antibody against PMCA 1, 2, 4. The apparent MW was calculated in reference to the known protein marker that was electrophoresised in the same gel.Result: In 8 cm gel the distance between 208 kDa and 126 kDa band was about 6.1 mm,while that of 20 cm gel was 32.8 mm. The distance between 126 kDa and 97 kDa was about 5.2 mm, while that of 20 cm gel was 20.2 mm. The migration distance differences of protein bands were significantly much longer in 20 cm gel than in 8 cm gel (P < 0.005).But the bands were generally more condensed in 8 cm gel. The apparent MW of PMCA1,2, 4 were 153.8, 153.5 and 152.9 kDa respectively. In the 20 cm gel, the apparent MW for PMCA1, 2, 4 was 153.1, 125.5 and 147.4 kDa respectively.Conclusion: Both the 20 cm gel and 8 cm gel successful identified PMCA 1,2, 4 in HLE B-3 cells. The apparent MW for PMCA1, 2, 4 was 153.8, 153.5 and 152.9 kDa respectively in 8 cm gel,and 153.1,125.5 and 147.4 kDa respectively in 20 cm gel.PMCA2 probably had some kinds of degradation during the long electrophoresis time in 20 cm gel.

    DSM-5 included criteria for an anxious distress specifier for major depressive disorder (MDD). In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project we examined whether a measure of the specifier, the DSM-5 Anxious Distress Specifier Interview (DADSI), was as valid as the Hamilton Anxiety Scale (HAMA) as a measure of the severity of anxiety in depressed patients. Two hundred three psychiatric patients with MDD were interviewed by trained diagnostic raters who administered the Structured Clinical Interview for DSM-IV (SCID) supplemented with questions to rate the DADSI, HAMA, and Hamilton Depression Rating Scale (HAMD). The patients completed self-report measures of depression, anxiety, and irritability. Sensitivity to change was examined in 30 patients. The DADSI and HAMA were significantly correlated (r = 0.60, p < 0.001). Both the DADSI and HAMA were more highly correlated with measures of anxiety than with measures of the other symptom domains. The HAMD was significantly more highly correlated with the HAMA than with the DADSI. For each anxiety disorder, patients with the disorder scored significantly higher on both the DADSI and HAMA than did patients with no current anxiety disorder. A large effect size of treatment was found for both measures (DADSI: d = 1.48; HAMA: d = 1.37). Both the DADSI and HAMA were valid measures of anxiety severity in depressed patients, though the HAMA was more highly confounded with measures of depression than the DADSI. The DADSI is briefer than the HAMA, and may be more feasible to use in clinical practice. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The impact of anxiety, seizure severity, executive dysfunction, subjectively perceived psychological deficits, and depression on social function in patients with epilepsy (PWE) was analyzed. A brief cognitive screening test (EpiTrack) and an estimation of the last 6 months' cumulative seizure severity (Chalfont seizure severity scale) were performed, and questionnaires on subjectively perceived cognitive deficits (c.I.-Skala), anxiety (State-Trait Anxiety Inventory, STAIX1 and STAIX2), depression (Self Rating Depression Scale, SDS), and social function (Soziale Aktivität Selbstbeurteilungsskala, SASS) were completed. Forty PWE (aged 41.8 years, SD 16; 24 female, 16 male) were analyzed. Thirty-eight point 5 percent had a score signifying depression in the SDS; 20% had a pathological result in at least one of the anxiety scores. The ANOVA revealed that only anxiety as a trait symptom (STAIX2) had a significant influence on social function apart from the other factors (panxiety impair the social function of patients with epilepsy apart from depression, cognitive function, and seizure severity.

    Meaningful comparison of depression symptoms requires that the measurement instrument has equivalent measurement properties among racial and ethnic groups. We tested the factorial validity and invariance of the Center for Epidemiologic Studies-Depression (CES-D) Scale among Black (n=610) and White (n=452) adolescent girls in the 12th grade. The invariance analyses were conducted by using LISREL 8.70 with maximum likelihood estimation and Satorra-Bentler scaled chi-square statistics and standard errors. The hypothesized second-order model (first-order factors: depressed affect, somatic and retarded activity, interpersonal, and positive affect; second-order factor: depression) demonstrated good overall fit in both groups. Comparison of nested models supported the between-group invariance of the overall factor structure, first- and second-order factor loadings, first-order factor variances, and the second-order factor variance. Item uniquenesses were not invariant. Our results support the hypothesis that a meaningful comparison of composite CES-D scores can be made between Black and White girls in the 12th grade.

    The Revised Child Anxiety and Depression Scale-Parent version (RCADS-P) is a self-report questionnaire that assesses dimensions of DSM-based anxiety and depressive disorders in children and adolescents. The present study examined the psychometric properties of the Turkish version in a clinical sample of 483 children and adolescents. The child and parent versions of the RCADS, parent versions of the Screen for Child Anxiety Related Emotional Disorders, the Strengths and Difficulties Questionnaire and Adolescent Symptom Inventory-Depression Scale were administered. Current psychiatric diagnoses were assessed via the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present Version. The RCADS-P demonstrated high internal consistency and test-retest reliability, and good convergent, divergent, and discriminant validity. Confirmatory factor analysis supported the DSM-related six-factor structure. With its demonstrated favorable psychometric properties, the Turkish RCADS-P is currently the only validated parent-report instrument that assesses DSM-based anxiety and depressive disorders in children and adolescents in Turkey.

However, there are no adequate scales for detecting possible diagnoses in the Chinese population. The aim of this study was to assess whether the Chinese version of the Gotland Male Depression Scale (CV-GMDS could identify male depression as effectively as the English version. Materials and methods: A total of 231 male outpatients were sampled from a men’s health polyclinic. We used questionnaires to evaluate the characteristics and mood status of participants, including the CV-GMDS, the Chinese version of the Beck Depressive Inventory II (CV-BDI-II, and the Chinese version of the Aging Males’ Symptoms (CV-AMS scale. Cronbach’s α-coefficient and Levene’s test were used to investigate internal consistency and homogeneity, respectively. External validity was evaluated using Spearman’s correlation coefficient. A factor analysis was conducted to evaluate the conceptual structure of the CV-GMDS, and a regression analysis was used to determine the relationship of the CV-AMS scale with the CV-GMDS and CV-BDI-II. Results: The mean age of the 231 participants was 46.1 years (standard deviation 11.0. Of the participants, 36.8% (n=85 were found to have depression according to the CV-GMDS and 34.6% (n=80 according to the CV-BDI-II. The internal consistency of the CV-GMDS was demonstrated by a Cronbach’s α of 0.933, and the test of homogeneity revealed a P-value of 0.762. The external validity for the CV-GDMS and CV-BDI-II was demonstrated

    Full Text Available Abstract Background The lack of culturally adapted and validated instruments for child mental health and psychosocial support in low and middle-income countries is a barrier to assessing prevalence of mental health problems, evaluating interventions, and determining program cost-effectiveness. Alternative procedures are needed to validate instruments in these settings. Methods Six criteria are proposed to evaluate cross-cultural validity of child mental health instruments: (i purpose of instrument, (ii construct measured, (iii contents of construct, (iv local idioms employed, (v structure of response sets, and (vi comparison with other measurable phenomena. These criteria are applied to transcultural translation and alternative validation for the Depression Self-Rating Scale (DSRS and Child PTSD Symptom Scale (CPSS in Nepal, which recently suffered a decade of war including conscription of child soldiers and widespread displacement of youth. Transcultural translation was conducted with Nepali mental health professionals and six focus groups with children (n = 64 aged 11-15 years old. Because of the lack of child mental health professionals in Nepal, a psychosocial counselor performed an alternative validation procedure using psychosocial functioning as a criterion for intervention. The validation sample was 162 children (11-14 years old. The Kiddie-Schedule for Affective Disorders and Schizophrenia (K-SADS and Global Assessment of Psychosocial Disability (GAPD were used to derive indication for treatment as the external criterion. Results The instruments displayed moderate to good psychometric properties: DSRS (area under the curve (AUC = 0.82, sensitivity = 0.71, specificity = 0.81, cutoff score ≥ 14; CPSS (AUC = 0.77, sensitivity = 0.68, specificity = 0.73, cutoff score ≥ 20.

    Full Text Available 1 Abstract 1.1 Background Suicide is a leading cause of perinatal maternal deaths in industrialised countries but there has been little research to investigate prevalence or correlates of postpartum suicidality. The Edinburgh Postnatal Depression Scale is widely used in primary and maternity services to screen for perinatal depressive disorders, and includes a question on suicidal ideation (question 10. We aimed to investigate the prevalence, persistence and correlates of suicidal thoughts in postpartum women in the context of a randomised controlled trial of treatments for postnatal depression. 1.2 Methods Women in primary care were sent postal questionnaires at 6 weeks postpartum to screen for postnatal depression before recruitment into an RCT. The Edinburgh Postnatal Depression Scale (EPDS was used to screen for postnatal depression and in those with high levels of symptoms, a home visit with a standardised psychiatric interview was carried out using the Clinical Interview Schedule-Revised version (CIS-R. Other socio-demographic and clinical variables were measured, including functioning (SF12 and quality of the marital relationship (GRIMS. Women who entered the trial were followed up for 18 weeks. 1.3 Results 9% of 4,150 women who completed the EPDS question relating to suicidal ideation reported some suicidal ideation (including hardly ever; 4% reported that the thought of harming themselves had occurred to them sometimes or quite often. In women who entered the randomised trial and completed the EPDS question relating to suicidal ideation (n = 253, suicidal ideation was associated with younger age, higher parity and higher levels of depressive symptoms in the multivariate analysis. Endorsement of 'yes, quite often' to question 10 on the EPDS was associated with affirming at least two CIS-R items on suicidality. We found no association between suicidal ideation and SF-12 physical or mental health or the EPDS total score at 18 weeks. 1

    BACKGROUND: Type D personality is an emerging risk factor in cardiovascular disease. We examined the psychometric properties of the Danish version of the Type D Scale (DS14) and the impact of Type D on anxiety and depression in cardiac patients. METHOD: Cardiac patients (n = 707) completed the DS14......, the Hospital Anxiety and Depression Scale, and the Eysenck Personality Questionnaire. A subgroup (n = 318) also completed the DS14 at 3 or 12 weeks. RESULTS: The two-factor structure of the DS14 was confirmed; the subscales negative affectivity and social inhibition were shown to be valid, internally...... consistent (Cronbach's alpha = 0.87/0.91; mean inter-item correlations = 0.49/0.59), and stable over 3 and 12 weeks (r = 0.85/0.78; 0.83/0.79; ps anxiety (beta, 0.49; p

    AIM: To evaluate the effects of depression on parameters of cell-mediated immunity in patients with cancers of the digestive tract.METHODS: One hundred and eight adult patients of both sexes with cancers of the digestive tract admitted between March 2001 and February 2002 in the Department of Medical Oncology, First Affiliated Hospital of Xi'an Jiaotong University were randomly enrolled in the study. The Zung self-rating depression scale (SDS), Zung self-rating anxiety scale(SAS), numeric rating scale (NRS) and social support rating scale (SSRS) were employed to evaluate the degree of depression and their contributing factors. In terms of their SDS index scores, the patients were categorized into depression group (SDS≥50) and non-depression group(SDS<50). Immunological parameters such as T-lymphocyte subsets and natural killer (NK) cell activities in peripheral blood were determined and compared between the two groups of patients.RESULTS: The SDS index was from 33.8 to 66.2 in the 108 cases, 50% of these patients had a SDS index more than 50. Similarly, the SAS index of all the patients ranged from 35.0 to 62.0 and 46.3% of the cases had a SAS index above 50. Cubic curve estimation showed that the depression was positively correlated with anxiety and negatively with social support. Furthermore, the depression correlated with the tumor type, which manifested in a descending order as stomach, gallbladder, pancreas, intestine, esophagus,duodenum and rectum, according to their correlativity. Step-wise regression analysis suggested that hyposexuality,dispidtment, agitation, palpitation, low CD56 and anxiety were the significant factors contributing to depression. More severe anxiety (49.7±7.5 vs 45.3±6.9, P<0.05), pain (6.5±2.8 vs4.6±3.2, P<0.05), poor social support (6.8±2.0 vs 7.6±2.1,P<0.05), as well as decline of lymphocyte count (0.33±0.09vs0.39±0.87, P<0.05) and CD56 (0.26±0.11 vs0.29±0.11,P<0.05) were noted in the depression group compared

    Objective To investigate the association between psychological stress and oxidative damage in TNM stage Ⅲ patients with poorly differentiated gastric adenecarcinoma (GA). Methods One hundred and six patients with newly diagnosed poorly differentiated GA were assessed using the Hamilton Depression Rating Scale (HAMD), Zung Self-rating Depression Scale (SDS), Zung Self-rating Anxiety Scale (SAS), Symptom Checklist 90 (SCL-90), activities of daily living (ADL) and other multiple-item qnestionnaires. Oxidative-stress-related parameters in serum and the expression of DNA repair genes were monitored during a pretreatment period. Results The patients were divided into depression and nondepression groups (Groups A and B, respectively) based on a HAMD score cutoff of 20. The mean SDS, SAS, SCL-90, ADL and passive coping scores were higher in Group A, whereas social support and quality of life were lower. Serum total antioxidant capacity, eatalase, superoxide dismutuse concentrations and anti-superoxide anion capacity (A-ASC) were significantly decreased in Group A, whereas serum malondialdehyde (MDA) and 8-hydroxy-deoxyguanosine (8-OHdG) levels were significantly increased. Pearson correlation analysis revealed that depression was pesitively correlated with MDA, SAS, SCL-90 and ADL, but negatively correlated with A-ASC. Furthermore, real-time PCR revealed that the expression levels of hOGG1 and APEX1 were increased in Group A. Conclusion Psychological stress might be related to impaired antioxidant system in patients with GA, and it presents the first evidence of the involvement of oxidative DNA damage in the pathogenesis of depression.

  17. Hyaluronan binding motifs of USP17 and SDS3 exhibit anti-tumor activity.

    Full Text Available BACKGROUND: We previously reported that the USP17 deubiquitinating enzyme having hyaluronan binding motifs (HABMs interacts with human SDS3 (suppressor of defective silencing 3 and specifically deubiquitinates Lys-63 branched polyubiquitination of SDS3 resulting in negative regulation of histone deacetylase (HDAC activity in cancer cells. Furthermore, USP17 and SDS3 mutually interact with each other to block cell proliferation in HeLa cells but the mechanism for this inhibition in cell proliferation is not known. We wished to investigate whether the HABMs of USP17 were responsible for tumor suppression activity. METHODOLOGY/PRINCIPAL FINDINGS: Similarly to USP17, we have identified that SDS3 also has three consecutive HABMs and shows direct binding with hyaluronan (HA using cetylpyridinium chloride (CPC assay. Additionally, HA oligosaccharides (6-18 sugar units competitively block binding of endogenous HA polymer to HA binding proteins. Thus, administration of HA oligosaccharides antagonizes the interaction between HA and USP17 or SDS3. Interestingly, HABMs deleted USP17 showed lesser interaction with SDS3 but retain its deubiquitinating activity towards SDS3. The deletion of HABMs of USP17 could not alter its functional regulation on SDS3-associated HDAC activity. Furthermore, to explore whether HABMs in USP17 and SDS3 are responsible for the inhibition of cell proliferation, we investigated the effect of USP17 and SDS3-lacking HABMs on cell proliferation by soft agar, apoptosis, cell migration and cell proliferation assays. CONCLUSIONS: Our results have demonstrated that these HABMs in USP17 and its substrate SDS3 are mainly involved in the inhibition of anchorage-independent tumor growth.

    Heavy metal- and organic-contaminated sites are ubiquitous, but few studies have been conducted to address such an issue. EDTA- and SDS-enhanced washing was studied for remediation of Pb- and/or marine diesel fuel (MDF)-contaminated soils. The feasibility of recovery and reuse of EDTA and SDS, as well as the physicochemical interactions among the chemical agents, contaminants and soils were extensively investigated using batch experiments. The optimal washing sequence was then determined. The experimental results showed that EDTA could be recovered and reused for four cycles without significant loss of its chelating capacity, while the extraction capability of SDS was noticeably reduced after each reuse cycle. The free phase of marine diesel fuel (MDF) in soils physically isolated the sorbed Pb on soils and thus reducing its extraction by EDTA. The presence of SDS alone or together with low concentration of EDTA was found to enhance Pb removal probably via electrostatic interaction and dissolution of soil organic matter. However, it hindered Pb extraction by high concentration of EDTA, because of the potential formation of complexes between some strongly-bound Pb and SDS, that are more resistant to desorption. Therefore, EDTA washing followed by SDS achieved the highest Pb removal efficiency. On the other hand, MDF removal by SDS was significantly hindered by coexisting Pb in soils, probably because the formation of Pb-dodecyl sulfate (DS) complex would decrease the effective amount of SDS available for forming micelles in solution and enhance MDF sorption. EDTA alone or together with SDS could enhance MDF removal, but the residual MDF after EDTA-washing became more resistant to SDS removal. Consequently, SDS washing followed by EDTA is considered as the optimal washing sequence for MDF removal.

    Background The Edinburgh Postnatal Depression Scale (EPDS) is widely recommended for perinatal anxiety and depression screening. However, many Aboriginal women find EPDS language complex and confusing, and providers find using it with Aboriginal women challenging. The two part Kimberley Mum’s Mood Scale (KMMS) was developed to improve screening: Part 1 is a Kimberley version of EPDS; Part 2 is a psychosocial tool that enables contextualisation of Part 1 scores. We aimed to determine if KMMS is a valid and acceptable method of identifying Kimberley Aboriginal perinatal women at risk of anxiety or depressive disorders compared to a semi-structured clinical interview. Methods Across 15 sites in the Kimberley, Western Australia, 97 Aboriginal women aged 16 years and older who intended to continue with their pregnancy or had a baby within the previous 12 months were administered the KMMS by trained healthcare providers who provided an overall assessment of no, low, moderate or high risk; 91 participants were then independently assessed by a blinded clinical expert using Diagnostic and Statistical Manual of Mental Disorders, 4th Edition criteria. A qualitative approach was used to determine KMMS’ acceptability. Results Part 1 had high internal consistency (Cronbach’s alpha, 0.89), and overall KMMS risk equivalence for screening for anxiety or depressive disorders was moderate (sensitivity, 83%; specificity, 87%; positive predictive value, 68%). Participants found the process easy and useful, and healthcare providers found KMMS more useful than EPDS. Part 2 allowed healthcare providers to ask questions that gave participants an opportunity to express themselves, resulting in a deeper understanding between them. Conclusion KMMS is an effective tool for identifying Kimberley Aboriginal perinatal women at risk of anxiety and depressive disorders.

    Influences of depression symptoms on the sweet taste threshold were investigated in healthy college students (30 males and 40 females). Depression symptoms were scored by SDS (Self-Rating Depression Scale), and anxiety levels by STAI (State- and Trait-Anxiety Inventory). Recognition thresholds for sucrose were determined. In female students, the menstrual phase on the day of the experiment was self-reported. Depression symptoms, anxiety levels, and the recognition threshold for sucrose were not different among the 3 groups, i.e. males, females in the follicular phase, and females in the luteal phase. Depression symptoms were positively correlated with state and trait anxiety in all groups. The sweet taste threshold was inversely correlated with depression symptoms (r=-0.472, p=0.031) and trait anxiety (r=-0.506, p=0.019) in females in the luteal phase. In males as well as females in the follicular phase, however, no correlation between sweet taste threshold and depression was found. The results show that the recognition threshold for sucrose reduces with increased depression in females with a higher anxiety trait, but only in the luteal phase. It is hypothesized that brain regions, which spatially overlap and are responsible for both aversive emotions and gustatory processing, are susceptible to periodic changes in gonadal hormones due to the menstrual cycle.

    Full Text Available Background: Acne is a common disorder among adolescents and young adults causing a considerable psychological impact including anxiety and depression. Isotretinoin, a synthetic oral retinoid is very effective in the treatment of moderate to severe acne. But there have been many reports linking isotretinoin to depression and suicide though no clear proof of association has been established so far. Objective: To determine whether oral isotretinoin increases the risk of depression in patients with moderate to severe acne. Materials and Methods: One hundred and fifty patients with moderate to severe acne were treated with oral isotretinoin 0.5 mg/kg/day for a period of 3 months. Their acne and depression scoring was done at baseline and then every month for the first 3 months and then at 6 months. Results: We found that the acne scoring reduced from 3.11 ± 0.49 to 0.65 ± 0.62 (P = < 0.001 at the end of 3 months. Also, the depression scoring decreased significantly from 3.89 ± 4.9 at the beginning of study to 0.45 ± 1.12 (P < 0.001 at the end of 3 months. Both the acne and depression scores continued to remain low at the end of 6 months at 0.5 ± 0.52 (P = < 0.001 and 0.18 ± 0.51 (P = < 0.001, respectively. Conclusions: Our study proves that oral isotretinoin causes significant clearance of acne lesions. It causes significant reduction in depression scores and is not associated with an increased incidence of depression or suicidal tendencies.

    Over the past few years, the topic of self-compassion has attracted increasing attention from both scientific and clinical fields. The Self-Compassion Scale (SCS) was created to specifically capture this way of being kind and understanding towards oneself in moments of turmoil. In this article, we present a French adaptation of the SCS. We first explore the psychometric properties of this adaptation and then investigate its relation to psychological well-being. As in the original version of the SCS, the French adaptation has a strong 6-factor structure but a weaker hierarchical second order structure. However the bi-factor model yields a good omega index suggesting the relevance of a single score accounting for self-compassion. Moreover, there was a relation between the SCS and classical outcomes such as a positive relation with psychological well-being and negative relation with depressive symptoms. We then hypothesized that self-compassion would have a moderating role on the relation between affect and depression. This hypothesis was confirmed: expressing negative affect is correlated with depressive symptoms; however, being kind with oneself lowers depressive symptoms even when expressing negative affect. In conclusion, this research presents a valid self-compassion measure for French-speaking researchers and clinicians and outlines the need for further research on the concept of self-compassion.

    We sought to examine the concordance of two suicidal ideation items from the Patient Health Questionnaire-9 (PHQ-9) and the Edinburgh Postnatal Depression Scale (EPDS), to evaluate the prevalence of suicidal ideation among pregnant women, and to assess the co-occurrence of suicidal ideation with antepartum depressive symptoms. A cross-sectional study was conducted among 1,517 pregnant women attending prenatal care clinics in Lima, Peru. Item 9 of the PHQ-9 assesses suicidal ideation over the last 14 days while item 10 of the EPDS assesses suicidal ideation in the past 7 days. The two suicidal ideation items have a high concordance rate (84.2 %) but a moderate agreement (the Cohen's kappa = 0.42). Based on the PHQ-9 and the EPDS, 15.8 and 8.8 % of participants screened positive for suicidal ideation, respectively. Assessed by the PHQ-9, 51 % of participants with suicidal ideation had probable depression. In prenatal care clinics, screening for suicidal ideation is needed for women with and without depressive symptoms. Future studies are needed to identify additional predictors of antepartum suicidality, determine the appropriate duration of reporting period for suicidal ideation screening, and assess the percentage of individuals with positive responses to the two suicidal ideation items at high risk of planning and attempting suicide.

    2012-05-01

    To apply a modern psychometric approach to validate the Behavioral Health Screen (BHS) Depression, Anxiety, and Suicidal Risk Scales among adolescents in primary care. Psychometric analyses were conducted using data collected from 426 adolescents aged 12 to 21 years (mean = 15.8, SD = 2.2). Rasch-Masters partial credit models were fit to the data to determine whether items supported the comprehensive measurement of internalizing symptoms with minimal gaps and redundancies. Scales were reduced to ensure that they measured singular dimensions of generalized anxiety, depressed affect, and suicidal risk both comprehensively and efficiently. Although gender bias was observed for some depression and anxiety items, differential item functioning did not impact overall subscale scores. Future revisions to the BHS should include additional items that assess low-level internalizing symptoms. The BHS is an accurate and efficient tool for identifying adolescents with internalizing symptoms in primary care settings. Access to psychometrically sound and cost-effective behavioral health screening tools is essential for meeting the increasing demands for adolescent behavioral health screening in primary/ambulatory care.

  12. The center for epidemiologic studies depression scale: a review with a theoretical and empirical examination of item content and factor structure.

    Directory of Open Access Journals (Sweden)

    R Nicholas Carleton

    Full Text Available BACKGROUND: The Center for Epidemiologic Studies Depression Scale (CES-D; Radloff, 1977 is a commonly used freely available self-report measure of depressive symptoms. Despite its popularity, several recent investigations have called into question the robustness and suitability of the commonly used 4-factor 20-item CES-D model. The goal of the current study was to address these concerns by confirming the factorial validity of the CES-D. METHODS AND FINDINGS: Differential item functioning estimates were used to examine sex biases in item responses, and confirmatory factor analyses were used to assess prior CES-D factor structures and new models heeding current theoretical and empirical considerations. Data used for the analyses included undergraduate (n = 948; 74% women, community (n = 254; 71% women, rehabilitation (n = 522; 53% women, clinical (n =84; 77% women, and National Health and Nutrition Examination Survey (NHANES; n = 2814; 56% women samples. Differential item functioning identified an item as inflating CES-D scores in women. Comprehensive comparison of the several models supported a novel, psychometrically robust, and unbiased 3-factor 14-item solution, with factors (i.e., negative affect, anhedonia, and somatic symptoms that are more in line with current diagnostic criteria for depression. CONCLUSIONS: Researchers and practitioners may benefit from using the novel factor structure of the CES-D and from being cautious in interpreting results from the originally proposed scale. Comprehensive results, implications, and future research directions are discussed.

    Full Text Available BACKGROUND: Previous studies suggest that electroacupuncture possesses therapeutic benefits for depressive disorders. The purpose of this study was to determine whether dense cranial electroacupuncture stimulation (DCEAS could enhance the antidepressant efficacy in the early phase of selective serotonin reuptake inhibitor (SSRI treatment of major depressive disorder (MDD. METHODS: In this single-blind, randomized, controlled study, patients with MDD were randomly assigned to 9-session DCEAS or noninvasive electroacupuncture (n-EA control procedure in combination with fluoxetine (FLX for 3 weeks. Clinical outcomes were measured using the 17-item Hamilton Depression Rating Scale (HAMD-17, Clinical Global Impression-severity (CGI-S, and Self-rating Depression Scale (SDS as well as the response and remission rates. RESULTS: Seventy-three patients were randomly assigned to n-EA (n = 35 and DCEAS (n = 38, of whom 34 in n-EA and 36 in DCEAS group were analyzed. DCEAS-treated patients displayed a significantly greater reduction from baseline in HAMD-17 scores at Day 3 through Day 21 and in SDS scores at Day 3 and Day 21 compared to patients receiving n-EA. DCEAS intervention also produced a higher rate of clinically significant response compared to n-EA procedure (19.4% (7/36 vs. 8.8% (3/34. The incidence of adverse events was similar in the two groups. CONCLUSIONS: DCEAS is a safe and effective intervention that augments the antidepressant efficacy. It can be considered as an additional therapy in the early phase of SSRI treatment of depressed patients. TRIAL REGISTRATION: Controlled-Trials.com ISRCTN88008690.

    To compare the effects of depression and chronic physical conditions on disability in elderly persons. Yoruba-speaking areas of Nigeria. Interviews. PATICIPANTS: Community-dwelling persons aged 65 and older. Face-to-face interviews were conducted with a representative sample of community-dwelling persons aged 65 and older (N=2,152) in the Yoruba-speaking areas of Nigeria (representing approximately 22% of the national population). Major depressive disorder (MDD) was assessed using the World Health Organization Composite International Diagnostic Interview. Chronic pain and medical disorders were assessed using self-report. Disorder-specific disability was evaluated using the Sheehan Disability Scale (SDS). MDD was highly comorbid with each of the medical conditions (odds ratio range 1.3-2.0). A higher proportion of persons with MDD (47.2%) were rated severely disabled globally than those with arthritis (20.6%), chronic spinal pain (24.2%), or high blood pressure (25.0%). Subjects with MDD were also more likely to be severely disabled in three of the four domains of the SDS. In pair-wise comparisons, persons with MDD had significantly higher levels of disability than those with any of the disorders, with differences in mean scores ranging between -3.74 and -27.50. To reduce the public health burden of depression, its prevention and treatment require more clinical and research attention than currently given by developing countries.

    Although a number of studies have examined the factor structure of the Edinburgh Postnatal Depression Scale (EPDS) in predominately White or African American samples, no published research has reported on the factor structure among Hispanic women who reside in the United States. The current study examined the factor structure of the EPDS among Hispanic mothers in the United States. Among 220 Hispanic women, drawn from a pediatric primary care setting, with an infant aged 0 to 10 months, 6 structural models guided by the empirical literature were evaluated using confirmatory factor analysis. Results supported a 2-factor model of depression and anxiety as the best fitting model. Multigroup models supported the factorial invariance across women who completed the EDPS in English and Spanish. These findings provide initial support for the 2-factor structure of the EPDS among Hispanic women in the United States. © 2014 Wiley Periodicals, Inc.

    Syntheses of CaCO3 crystals in reverse microemulsion solutions containing 1-(1,1,3,3-tetramethylbutyl)-4-hydroxypolyethoxybenzene (Tx-100), sodium dodecyl sulfate (SDS) and their equimolar mixture were carried out at room temperature respectively. The crystal phase of CaCO3 is changed from calcite at low concentrations to vaterite at high concentrations of SDS and Tx-100. From rods at low concentration to olivary spheres at high concentration, SDS can influence the morphology of CaCO3 significantly, while almost no such effect for Tx-100. Hollow spheres, olivary spheres and even two fused olivary spheres of CaCO3 were produced at different concentrations of Tx-100-SDS, and the variation of crystal phase is opposite to that in the presence of SDS or Tx-100 alone. The effects of interaction of SDS with Tx-100 on morphology and crystal phase of CaCO3 were discussed. It was estimated to put forward that the formation of hollow CaCO3 crystals was caused by the collaborating actions of SDS template and TX-100 inhibition.

    The Arabidopsis SDS (SOLO DANCERS) and RCK (ROCK-N-ROLLERS) genes are important for male meiosis, but it is still unknown whether they represent conserved functions in plants. We have performed phylogenetic analy-ses of SDS and RCK and their respective homologs, and identified their putative orthologs in poplar and rice. Quan-titative real-time RT-PCR analysis indicated that rice SDS and RCK are expressed preferentially in young flowers, and transgenic RNAi rice lines with reduced expression of these genes exhibited normal vegetative development, but showed significantly reduced fertility with partially sterile flowers and defective pollens. SDS deficiency also caused a decrease in pollen amounts. Further cytological examination of male meiocytes revealed that the SDS deficiency led to defects in homolog interaction and bivalent formation in meiotic prophase I, and RCK deficiency resulted in defec-tive meiotic crossover formation. These results indicate that rice SDS and RCK genes have similar functions to their Arabidopsis orthologs. Because rice and Arabidopsis, respectively, are members of monocots and eudicots, two largest groups of flowering plants, our results suggest that the functions of SDS and RCK are likely conserved in flowering plants.

    Sds22p is a conserved, leucine-rich repeat protein that interacts with the catalytic subunit of protein phosphatase 1 (PP1(C)) and which has been proposed to regulate one or more functions of PP1(C) during mitosis. Here we show that Saccharomyces cerevisiae Sds22p is a largely nuclear protein, most of which is present as a sTable 1:1 complex with yeast PP1(C) (Glc7p). Temperature-sensitive (Ts(-)) S. cerevisiae sds22 mutants show profound chromosome instability at elevated growth temperatures but do not confer a cell cycle stage-specific arrest. In the sds22-6 Ts(-) mutant, nuclear Glc7p is both reduced in level and aberrantly localized at 37 degrees C and the interaction between Glc7p and Sds22p in vitro is reduced at higher temperatures, consistent with the in vivo Ts(-) growth defect. Like some glc7 mutations, sds22-6 can suppress the Ts(-) growth defect associated with ipl1-2, a loss of function mutation in a protein kinase that is known to work in opposition to PP1 on at least two nuclear substrates. This, together with reciprocal genetic interactions between GLC7 and SDS22, suggests that Sds22p functions positively with Glc7p to promote dephosphorylation of nuclear substrates required for faithful transmission of chromosomes during mitosis, and this role is at least partly mediated by effects of Sds22p on the nuclear distribution of Glc7p

    Full Text Available BACKGROUND: On May 12th 2008, an earthquake with a magnitude of 8.0 on the Richter scale struck China, causing a large number of casualties and significant economic losses. By interviewing 2080 survivors of Wenchuan earthquake, the objective of this study is to estimate the role of different types of social support as possible moderating factors between anxiety and depression. METHODS: A stratified random sampling strategy about the cross-sectional study was adopted. The self-rating anxiety scale (SAS, Self-Rating Depression Scale (SDS and Social Support Rating Scale (SSRS were used. A total of 2080 adult survivors of the Wenchuan earthquake from 19 damaged countries participated in the survey. Correlation analysis and regression analysis were performed to evaluate the moderating role of social support on the relationship between anxiety and depression. RESULTS: One year after the Wenchuan earthquake, anxiety and depression were found to be 37.6% and 40.7%, respectively. Demographic characteristics were seen as significant in the cases of depression, except for age (p=0.599, while age and education level were not found to be significant for anxiety. The results showed that social support, especially subjective support could moderate the association between anxiety and depression. CONCLUSIONS: Social support should be particularly focused on female survivors, those of the Han ethnic group, and those with a lower level of education and a lower income. Psychological intervention and care for survivors should focus on those most disoriented by the disaster.

    Full Text Available The purpose of this study is to investigate the prevalence rate and risk factors of depression in outpatients who were diagnosed with PE. Therefore, between September 2009 and September 2011, 1801 outpatients at andrology clinics were enrolled and consented to participate in our survey by completed a verbal questionnaire. It included the following: (1 demographic data (e.g., age, body mass index, (2 PE duration, medical history, and sexual history, (3 self-estimated intravaginal ejaculatory latency times, (4 the Zung Self-rating Depression Scale (SDS, and (5 the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI and (6 the International Index of Erectile Function (IIEF-5. The results showed that a total of 1,206 patients were diagnosed with PE. The prevalence rate of depression in these PE patients was 26.78%. Depression was associated with PE duration, NIH-CPSI score, and IIEF-5 score. Risk factors for depression specifically included PE durations for 13–24, 25–60, or ≥61 months, CPSI scores of 15–30 or ≥31, and IIEF-5 scores <22. These findings suggested that several associated factors (PE duration, CPSI scores, and IIEF-5 scores were the risk factors of depression in men with PE.

    The Youth Anxiety Measure for DSM-5 (YAM-5) is a newly developed rating scale for assessing anxiety disorder symptoms of children and adolescents in terms of the contemporary classification system. In the present study, 187 children aged 8-12 years completed the new measure as well as the trait version of the State-Trait Anxiety Inventory for Children (STAIC), the Short Form of the Fear Survey Schedule for Children-Revised (FSSC-R-SF), the Spence Children's Anxiety Scale (SCAS), the Selective Mutism Questionnaire (SMQ), and the Children's Depression Inventory (CDI). Results indicated that part one of the YAM-5, which measures symptoms of the major anxiety disorders, was most substantially linked with the trait anxiety scale of the STAIC, whereas part two, which measures phobic symptoms, was most clearly associated with the FSSC-R-SF. The correlation between the YAM-5 and the SCAS was also robust, and particularly strong correlations were found between subscales of both questionnaires that assessed similar symptoms. Further, the selective mutism subscale of the YAM-5 was most clearly linked to the SMQ. Finally, the YAM-5 was also significantly correlated with depression symptoms as indexed by the CDI. These findings provide further support for the concurrent validity of the YAM-5. Copyright © 2017 Elsevier Ltd. All rights reserved.

    For the Center for Epidemiologic Studies Depression Scale (CES-D) ratings, the study examined support for a bifactor model, and also the internal consistency reliability and external validity of the factors in this model. Participants (N = 1,178) were older adults from the general community who completed the CES-D. Confirmatory factor analysis of their ratings indicated support for the bifactor model. For this model, the general factor explained most of the covariance in the scores of the CES-D items for Depressed Affect, Somatic Symptoms and Retarded Activity, and Interpersonal Difficulties items. Most of the covariance in the scores of the Positive Affect (PA) scale was explained by its own specific factor. Additional analyses showed support for internal consistencies and external validities of general factors based on all the CES-D items, and when PA items were excluded, and also the PA-specific factor. The findings support the use of a total CES-D score without the PA items and also the concurrent use of the PA scale score. © The Author(s) 2014.

    The internalized stigma of mental illness impedes recovery and is associated with increased depression, reduced self-esteem, reduced recovery orientation, reduced empowerment, and increased perceived devaluation and discrimination. The Internalized Stigma of Mental Illness (ISMI) scale is a 29-item self-report questionnaire developed with consumer input that includes the following subscales: Alienation, Discrimination Experience, Social Withdrawal, Stereotype Endorsement, and Stigma Resistance. Here we present a 10-item version of the ISMI containing the two strongest items from each subscale. Participants were all outpatient veterans with serious mental illness. Following the rigorous scale-reduction methods set forth by Stanton and colleagues (2002), we selected the 10 items, tested the psychometrics of the shortened scale in the original validation sample (N = 127), and cross-checked the results in a second dataset (N = 760). As expected, the ISMI-10 retained the essential properties of the ISMI-29, including adequate internal consistency reliability and external validity in relation to depression, self-esteem, recovery orientation, perceived devaluation and discrimination, and empowerment. The ISMI-10 scores are normally distributed and have similar descriptive statistics to the ISMI-29. The reliability and depression findings were replicated in a cross-validation sample. We conclude that the ISMI-10 has strong psychometric properties and is a practical, reliable, and valid alternative to the original ISMI-29. Future work should test the ISMI-10 in more diverse samples. This shorter version should reduce respondent burden in program evaluation projects that seek to determine whether participation in psychosocial rehabilitation programming reduces internalized stigma.

    An amphiphilic fluorescent probe, 3-dodecylamino dihydrogen imidazo[2,l-a]benz[de]isoquinolin-7-one (compound 3), was used to sense the aggregate formation process of bovine serum albumine (BSA), sodium dode- cyl sulfate (SDS) and their mixed system. The fluorescence intensity of 3 was significantly affected by the adding order of SDS and BSA, and SDS can be distinguished from other surfactants with the aid of BSA, but only when 3 is allowed to interact with BSA first. The results revealed that compound 3 is preferentially sited in the hydrophobic region of BSA, and thermodynamically in SDS-BSA mixed aggregate. Sodium phosphate buffer solution (PBS) and BSA played important but distinct roles in distinguishing SDS micelle from the others.

    This paper presents a model study to understand the effect of surfactants on the physicochemical properties of human hair. FT-IR ATR spectroscopy has been employed to understand the chemical changes induced by sodium dodecyl sulfate (SDS) on human scalp hair. In particular, the SDS induced changes in the secondary structure of protein present in the outer protective layer of hair, i.e. cuticle, have been investigated. Conformational changes in the secondary structure of protein were studied by curve fitting of the amide I band after every phase of SDS treatment. It has been found that SDS brings rearrangements in the protein backbone conformations by transforming β -sheet structure to random coil and β -turn. Additionally, AFM and SEM studies were carried out to understand the morphological changes induced on the hair surface. SEM and AFM images demonstrated the rupture and partial erosion of cuticle sublayers. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available The Center for Epidemiologic Studies Depression Scale (CES-D is a commonly used instrument to measure depressive symptomatology. Despite this, the evidence for its psychometric properties remains poorly established in Chinese populations. The aim of this study was to validate the use of the CES-D in Chinese primary care patients by examining factor structure, construct validity, reliability, sensitivity and responsiveness.The psychometric properties were assessed amongst a sample of 3686 Chinese adult primary care patients in Hong Kong. Three competing factor structure models were examined using confirmatory factor analysis. The original CES-D four-structure model had adequate fit, however the data was better fit into a bi-factor model. For the internal construct validity, corrected item-total correlations were 0.4 for most items. The convergent validity was assessed by examining the correlations between the CES-D, the Patient Health Questionnaire 9 (PHQ-9 and the Short Form-12 Health Survey (version 2 Mental Component Summary (SF-12 v2 MCS. The CES-D had a strong correlation with the PHQ-9 (coefficient: 0.78 and SF-12 v2 MCS (coefficient: -0.75. Internal consistency was assessed by McDonald's omega hierarchical (ωH. The ωH value for the general depression factor was 0.855. The ωH values for "somatic", "depressed affect", "positive affect" and "interpersonal problems" were 0.434, 0.038, 0.738 and 0.730, respectively. For the two-week test-retest reliability, the intraclass correlation coefficient was 0.91. The CES-D was sensitive in detecting differences between known groups, with the AUC >0.7. Internal responsiveness of the CES-D to detect positive and negative changes was satisfactory (with p value 0.2. The CES-D was externally responsive, with the AUC>0.7.The CES-D appears to be a valid, reliable, sensitive and responsive instrument for screening and monitoring depressive symptoms in adult Chinese primary care patients.

    Full Text Available We investigated the efficacy of S-Adenosyl-L-Methionine (SAMe augmentation in patients with treatment-resistant depressive disorder (TRD. Thirty-three outpatients with major depressive episode who failed to respond to at least 8 weeks of treatment with two adequate and stable doses of antidepressants were treated openly with fixed dose of SAMe (800 mg for 8 weeks, added to existing medication. The primary outcome measure was the change from baseline in total score on Hamilton Rating Scale for Depression (HAM-D. The Clinical Global Impression of Improvement (CGI-I was rated at the endpoint. Patients with a reduction of 50% or more on HAM-D total score and a CGI-I score of 1 or 2 at endpoint were considered responders; remission was defined as a HAM-D score ≤7. Secondary outcome measures included the Snaith-Hamilton Pleasure Scale (SHAPS and the Sheehan Disability Scale (SDS. At 8 weeks, a significant decrease in HAM-D score was observed with response achieved by 60% of the patients and remission by 36%. Also a statistically significant reduction in SHAPS and SDS was observed. Our findings indicate that SAMe augmentation may be effective and well tolerated in stage II TRD. However, limitations of the present study must be considered and further placebo-controlled trials are needed.

    We present a kinetic study of the effects of sodium dodecyl sulfate (SDS) concentration on reduction and aggregation of Ag(+) and Au(3+) ions in aqueous solutions. There are distinct differences between the surface plasmon absorption bands of Ag nanoparticles at different concentrations of SDS. The results reveal the existence of two competing SDS-induced processes: stabilization of the Ag nanoparticles due to adsorption and aggregation of the Ag nanoparticles due to increase in ionic strength. However, SDS induced aggregation of Au nanoparticles is negligible because of less surface passivity as evident from eaq(-) reaction with AuCl4(-). Nevertheless, the average size of the Ag and Au nanoparticles remains almost similar at all SDS concentrations. UV-Vis spectrophotometry and transmission electron microscopy are used to characterize the nanoparticles. Moreover, it is shown that these SDS-capped Ag, Au and Au/Ag bimetallic nanoparticles could function as catalysts for the reduction of o-nitro aniline in the presence of NaBH4.

A total of 1,953 patients with acute ischemic stroke were enrolled into a multicentered and prospective cohort study. The HDRS-17 was used to assess symptoms at 2 weeks after ischemic stroke. The Modified Ranking Scale (mRS) scores of 3-6 points and 0-2 points were regarded as poor outcome and benign outcome, respectively. At 1 year, 1,753 (89.8 %) patients had mRS score data. After adjusting for the confounders, patients with a total HDRS-17 score of ≥ 8 had a worse outcome at 1 year (OR = 1.62, 95 % CI 1.18-2.23). Symptoms of suicide (OR = 1.89, 95 % CI 1.27-2.83), decreased or loss of interest of work (OR = 1.89, 95 % CI 1.38-2.58), retardation (OR = 1.74, 95 % CI 1.27-2.38), psychic anxiety (OR = 1.72, 95 % CI 1.26-2.34), and agitation (OR = 1.61, 95 % CI 1.08-2.40) increased the risks for poor outcome by >60 %, respectively. Depressed mood, somatic anxiety, somatic symptoms-gastrointestinal, and early insomnia also increased the risk for poor outcome by nearly 50 %, respectively. A total HDRS-17 score of ≥ 8, and suicide, decreased or loss of interest of work, anxiety, agitation, retardation, depressed mood, somatic anxiety, somatic symptoms-gastrointestinal, and early insomnia of the HDRS-17 factors at 2 weeks after ischemic stroke increase the risk for poor outcome at 1 year.

    Full Text Available Early identification of anxiety among youth is required to prevent them from going unrecognised and untreated by mental health professionals. A precise identification of the young person's primary difficulty is also required to guide treatment programs. Availability of a valid and easily administrable assessment tool is crucial for identifying youth suffering from anxiety disorders. The purpose of the present study was therefore to examine the psychometric properties of the Danish version of the Revised Children's Anxiety and Depression Scale (RCADS. A total of 667 youth from community schools (4(th through 9(th grade across Denmark participated in the study. The psychometric properties of the RCADS-(DAN resembled those reported in US and Europe. Within scale reliability was excellent with Chronbach's alpha of.96. All subscales also showed good to excellent internal reliability. The study provides convincing evidence that the RCADS-(DAN is a valid assessment tool for screening anxiety in Danish youth.

    Microbial fuel cells (MFCs) generate current via electrochemical reactions produced by bacteria attached to the anode that oxidize organic matter. Due to their high volume use in household products, some concentration of surfactant will reach wastewater treatment plants. The average surfactant concentration in wastewater ranges from 10 to 20 mg L-1, and up to 300 mg L-1, for domestic and industrial wastewaters, respectively. This study aimed to demonstrate the feasibility of enhancing power production by adding Tween 80 and SDS surfactants to air-cathode MFCs, and their effect in cell viability at the anodic biofilm. In order to analyze the effect of anionic and nonionic surfactants in MFCs performance, eight MFCs were spiked with two types of surfactants, the anionic surfactant sodium dodecyl sulfate (SDS) and the nonionic surfactant Tween® 80 at two different concentrations 10 and 100 mg L-1. Cell viability at the anodic biofilms was examined using the LIVE/DEAD BacLight viability assay and images were visualized with a confocal laser scanning microscope. The electrochemical results demonstrate that, for an air-cathode MFC operating on 1 g L-1 acetate in a fed-batch mode, reactors where SDS was added show a lower overall performance, maximum PD of 544 mW m-2, CE of 12.3%, Rint of 322 Ω (10 mg L-1) and maximum PD of 265 mW m-2, CE of 9.4%, Rint of 758 Ω (100 mg L-1). Reactors where Tween 80 was added show quite stable performance, maximum PD of 623 mW m-2, CE of 15.4%, Rint of 216 Ω (10 mg L-1) and maximum PD of 591 mW m-2, CE of 10.8%, Rint of 279 Ω (100 mg L-1), compared with reactors operating at only acetate as a substrate, maximum PD of 574 mW m-2. Confocal microscopy images confirm this observation and biofilm viability appeared severely compromised in SDS reactors, especially at high concentrations. This study has opened up a whole new research area in determining which types of surfactants are toxic to the anodic biofilm and to further investigate the

    Full Text Available Given that public transportation networks are often worse in rural areas than in urban areas, it is difficult for elderly non-drivers to access health-promoting goods, services, and resources related to mental health. Moreover, geographical location, assessed by elevation, could modify this association in a rural area. The aim of this study was to test whether the association between car driving (being a driver or not and depression, as measured by the Zung Self-Rating Depression Scale (SDS, varied by elevation. Data were collected from a cross-sectional study conducted in the town of Ohnan located in a rural area of Japan. After excluding participants with missing data (n = 26, 876 participants were analysed in this study. After adjustment for potential confounders, being a non-driver had a significantly higher odds ratio of SDS (40+ among elderly people living at a low elevation (odds ratio = 2.17, 95% confidence interval = 1.28–3.71. However, similar findings were not observed among elderly people living at a high elevation. These results suggest that car driving importantly predicts depression in elderly people living at relatively low elevations in rural areas.

    Objective To explore the effects of SDS, PBS re-dissolvent solutions on fluorescence values of radioallergosorbent test (RAST) inhibition.Methods Dermatophagoides pterronyssinus allergen immunoCAP and UniCAP 100 System were used. The Sera Pool consisted of 20 Dermatophagoides pterronyssinus allergic patients sera, their specific IgE fluorescence values were between 12 505 and 24 776.Results Fluorescence value percentages decreased: 62.9%, 54.1%, 43.5%, 6.7%, 3.7%, 2.6%, 2.2%, and 1.4%respectively, when SDS concentrations were at 2%, 1%, 0.5%, 0.25%, 0.1%, 0.05%, 0.025%, and 0.01%. Fluorescence values decreased more than 5% with SDS concentrations equal to 0.25% or higher. PBS in 0.1 and 0.01 mol/L concentrations decreased fluorescence values 2.9% and 0.9% respectively.Conclusions SDS is a commonly used surfactants in allergen extract and re-dissolvent prepared allergen precipitation for RAST inhibition. Thus effects of surfactants (e.g. SDS) upon the RAST inhibition tests must be considered when they were used as re-dissolvent agents to improve protein resolution in RAST inhibition.

  10. Effects of dodecanol on the adsorption kinetics of SDS at the water-hexane interface.

    Even though sodium dodecyl sulphate (SDS) is the most frequently studied surfactant, its properties at liquid interfaces are not easily accessible. This is mainly caused by the fact that in aqueous solution SDS is subject to hydrolysis, by which the homologous dodecanol (C12OH) is formed. Due to its enormously high surface activity it competes with SDS at the interface. We demonstrate here that this "natural" impurity C12OH does not remarkably affect the adsorption dynamics of SDS at the water/hexane interface, due to its high solubility in hexane. Therefore, the dynamic adsorption properties can be determined independent of disturbing dodecanol effects. The surfactant adsorbs diffusion controlled and the interfacial tension isotherm at the water/hexane interface is well described by a Frumkin model. However complementary experiments via direct admixture of dodecanol in hexane indicate a significant decrease in interfacial tension of the water-hexane interface at concentrations higher than 10(-3) mol/l in hexane. This condition may happen when the oil phase is distributed as small droplets in a high concentrated solution of SDS. The distribution coefficient of C12OH between water and hexane is estimated from adsorption experiments to be K(p)=c(o)/c(w)=6.7×10(3).

  11. Application and Mechanism of Anionic Collector Sodium Dodecyl Sulfate (SDS in Phosphate Beneficiation

    Full Text Available Phosphate ore is a valuable strategic resource. Most phosphate ore in China is collophane. Utilization of mid-low grade collophane is necessary to maintain social sustainable development. The gravity-flotation combination separation process can be utilized to separate mid-low grade collophane, but the process consumes a large quantity of acid in the reverse stage. Sodium dodecyl sulfate (SDS was used as a dolomite collector in this study to reduce the acid consumption of collophane flotation. SDS effectively removed dolomite from the gravity concentrate when no other reagents were present. Flotation test results showed that, compared to the conventional gravity-flotation process, the proposed SDS-based process reduced phosphoric acid dosage from 6.1 kg/t to 3.9 kg/t with similar separation results. The SDS action mechanisms on dolomite were further investigated by zeta potential analysis, single mineral flotation tests, infrared spectrum detection, and theoretical analysis. The results indicate that the SDS adsorption on dolomite is mainly physical adsorption, and that favorable separation effects between collophane and dolomite may be attributed to physical adsorption and entrainment. In addition, it also indicates that the physical adsorption can be utilized to remove dolomite from phosphate on account of zeta potential differences when the separate feed is coarse.

    This work addresses structural and nonequilibrium effects of the interactions between well-defined cationic poly(amidoamine) PAMAM dendrimers of generations 4 and 8 and the anionic surfactant sodium dodecyl sulfate (SDS) at the hydrophilic silica-water interface. Neutron reflectometry and quartz crystal microbalance with dissipation monitoring were used to reveal the adsorption from premixed dendrimer/surfactant solutions as well as sequential addition of the surfactant to preadsorbed layers of dendrimers. PAMAM dendrimers of both generations adsorb to hydrophilic silica as a compact monolayer, and the adsorption is irreversible upon rinsing with salt solution. SDS adsorbs on the dendrimer layer and at low bulk concentrations causes the expansion of the dendrimer layers on the surface. When the bulk concentration of SDS is increased, the surfactant layer consists of aggregates or bilayer-like structures. The adsorption of surfactant is reversible upon rinsing, but slight changes of the structure of the preadsorbed PAMAM monolayer were observed. The adsorption from premixed solutions close to charge neutrality results in thick multilayers, but the surface excess is lower when the bulk complexes have a net negative charge. A critical examination of the pathway of adsorption for the interactions of SDS with preadsorbed PAMAM monolayers and premixed PAMAM/SDS solutions with hydrophilic silica revealed that nonequilibrium effects are important only in the latter case, and the application of a thermodynamic model to such experimental data would be inappropriate.

    While the most serious of depressive illnesses in the elderly is major depressive disorder, patients' quality of life can be significantly impacted by dysthmic disorder, sub-threshold depression (minor depression), or a depressive disorder due to a general medical condition, all of which have been shown to be more prevalent than major depression in the community dwelling population of older adults. Older adults are also more likely to develop grief reaction and frequently deal with issues of bereavement. This review will discuss the diagnoses of all relevant depressive diagnoses that primary care physicians are likely to encounter. Among the many different assessment tools that screen for depression the briefest instruments are a two-question screening tool recommended by the U.S. Preventive Services Task Force and, specifically developed for older adults, the Geriatric Depression Scale (GDS) that is available in a short 15- Yes/No-question version. Many medical illnesses are associated with depressive symptoms. The focus in this review is on dementing illnesses/cerebrovascular disease, dementia of the Alzheimer's type, and Parkinson disease. First-line pharmacological therapy of depression includes selective serotonin inhibitors (SSRIs), and serotonin-norepinephrine reuptake inhibitors (SNRIs). Side effects of particular drugs can often be geared towards achieving additional benefits, e.g. weight gain associated with the use of some SSRISs may be helpful for patients with dementia.

    Full Text Available A State Depression Scale was developed in order to register variations of depressive mood. The Scale has satisfactory reliability, as shown by its internal homogeneity and temporal stability. Concurrent validity of the Scale indicated that the Scale correlates with a POMS-D scale (r = 0.41; p < 0.00, and with the Depressive Personality Scale (r = 0.36; p < 0.00. Divergent validity of the Scale was tested by Scale's correlation with the two measures of state anxiety (STAI-S and POMS-A and was shown to be unsatisfactory since it was as high as the Scale's correlation with scales of depressive affect. Principal Component Analysis extracted four factors: two broader factors, which included depressive-affective contents combined with anxious and depressive-cognitive symptoms, respectively; and another two factors which related to motivational and behavioral characteristics. Sensitivity of the Scale was tested in an experimental setting involving induction of depressive and euphoric mood. The Scale showed high ability to register changes following induction of depressive mood. .

    The electrochemical oxidation of L-cysteine in an SDS/BA/H2O microemulsion system was studied with the methods of ultramicroelectrode cyclic voltammetry and AC impedance. The catalytic efficiency of the microemulsion on the electrochemical oxidation increases with the increase of BA or SDS content, but decreases with the increase of the water content because of the effects of BA, SDS and water on the solubilization of L-cysteine in the microemulsion. Furthermore, the catalytic efficiency of the bicontinuous structure is greater than that of an O/W microemulsion system. The results derived from both the rate constant k0 and Gibbs free energy ΔG≠ accord with those from the catalytic efficiency.

    Full Text Available SDS is a meiosis specific cyclin-like protein and required for DMC1 mediated double-strand break (DSB repairing in Arabidopsis. Here, we found its rice homolog, OsSDS, is essential for meiotic DSB formation. The Ossds mutant is normal in vegetative growth but both male and female gametes are inviable. The Ossds meiocytes exhibit severe defects in homologous pairing and synapsis. No γH2AX immunosignals in Ossds meiocytes together with the suppression of chromosome fragmentation in Ossds-1 Osrad51c, both provide strong evidences that OsSDS is essential for meiotic DSB formation. Immunostaining investigations revealed that meiotic chromosome axes are normally formed but both SC installation and localization of recombination elements are failed in Ossds. We suspected that this cyclin protein has been differentiated pretty much between monocots and dicots on its function in meiosis.

    Objective To compare the diagnostic validity of 4 commonly used assessment scales for depression in schizophrenia. Methods The study population consisted of 100 schizophrenic patients who met CCMD-3 criteria for schizophrenia. Depression in the study subjects was defined by the CCMD - 3 criteria for a major depressive episode. The following 4 depression scales were assessed for their diagnostic validity as measures of depressive disorder in schizophrenia-, the Calgary Depression Scale for Schizophrenia (CDSS-C),the Montgomery-Asberg Depression Rating Scale ( MADRS) , the Hamilton Rating Scale for Depression (HAMD-24) ,and the depression subscale of the PANSS (PANSS-D). At the same time, we also undertook the negative subscale of the PANSS( PANSS-N) and the Rating Scale for Extrapyramidal Side Effects(RSESE). Results (1) There were 22 patients who met the CCMD-3 criteria for a major depressive episode among the 100 schizophrenia patients, so the incidence of depression was 22%. (2)The depression scales were found to be highly intercorrelated with each other. Of the 4 depression scales studied, only CDSS - C can discriminate between depression and a PANSS negative symptoms subscale score or negative item scores or a RSESE score. (3)The areas under the receiver operating characteristic curves of the CDSS-CMARDS,HAMD-24,and PANSS-D were 0. 933,0. 826, 0. 883 and 0. 887 respectively. The area under the receiver operating characteristic curve of the CDSS-C was significantly greater than those of MARDS, HAMD-24, and PANSS-D. Conclusions Our study suggests that the CDSS-C may provide optimal assessment on depression in patients with schizophrenia and is feasible to attempt to use in the clinic.%目的 比较四种抑郁量表对精神分裂症抑郁症状的诊断效能.方法 100例符合CCMD-3精神分裂症诊断标准的患者进入研究,以CCMD-3抑郁发作标准判断是否存在有抑郁症状,同时进行CDSS-C、MADRS、HAMD-24、PANSS及RSESE测评.结果 (1

    Full Text Available Objective To explore the relationship of post-stroke depression (PSD with neurological function deficits and activities of daily living. Methods A total of 160 patients with stroke from August 2012 to September 2013 in Department of Neurology in our hospital were enrolled. Self-Rating Depression Scale (SDS, Hamilton Depression Rating Scale-17 Items (HAMD-17, National Institutes of Health Stroke Scale (NIHSS and Barthel Index (BI were used to assess depression,  neurological function deficits and activities of daily living of stroke patients.  Results A total of 65 patients (40.63% appeared depression after stroke. Compared with non-PSD group, patients in PSD group presented more serious neurological function deficits (P = 0.045 and less activities of daily living (P = 0.000. The PSD group was further divided into 3 subgroups: mild, moderate and severe depression. Along with the increase of severity of PSD, NIHSS score increased (P = 0.000, 0.000, 0.000 while Activities of Daily Living (ADL score decreased (P = 0.000, 0.000, 0.000. Pearson correlation analysis suggested that HAMD score was positively correlated with NIHSS score (r = 0.534, P = 0.005, and negatively correlated with ADL score (r = -0.645, P = 0.002. Conclusions PSD is closely related with the degree of neurological function deficits and activities of daily living. Curing the primary disease, reducing neurological dysfunction, taking early rehabilitation therapy, and improving the patients' activities of daily living will be helpful to alleviate the degree of PSD. DOI: 10.3969/j.issn.1672-6731.2016.05.005

    Full Text Available The effect of remaining sodium dodecyl sulfate (SDS used in washing steps on further leaching of proteins from the deproteinized rubber films was investigated. High-Ammonia Natural Rubber Latex (HANRL was diluted with 0.01% w/v potassium hydroxide solution to obtain about 30% dry rubber content (DRC and it is called diluted NRL. The untreated NRL was directly casted to a film (sample 0. Sample 1 was prepared by centrifugation of diluted NRL at 5000 rpm for 1 min. Sample 1-2 was prepared by washing Sample 1 with 0.5%wt SDS solution. Sample 1-3 was prepared by washing Sample 1-2 with 0.1%wt SDS solution. After that they were casted into films. The dried films were checked for the extractable protein (EP content by modified Lowry method and nitrogen content according to SMR: Bulletin No.7-1992. The EP content of Sample 1 film was less than the untreated (Sample 0 one but the EP content was increased after washing with 0.5%wt SDS solution and then dropped slightly after washing again with 0.1%wt SDS solution. In contrast, nitrogen content and FTIR spectra confirmed that the total amount of proteins in films was decreased when they underwent more treating steps. This finding suggested that although overall protein content decreased, the remaining SDS on the films could facilitate further leaching of EP from the film surface when it was in contact with extraction medium (PBS or synthetic sweat under condition with shear force. The use of this deproteinized film should, therefore, be done with care.

  7. Preparative SDS PAGE as an Alternative to His-Tag Purification of Recombinant Amelogenin

    2017-06-01

    Full Text Available Recombinant protein technology provides an invaluable source of proteins for use in structure-function studies, as immunogens, and in the development of therapeutics. Recombinant proteins are typically engineered with “tags” that allow the protein to be purified from crude host cell extracts using affinity based chromatography techniques. Amelogenin is the principal component of the developing enamel matrix and a frequent focus for biomineralization researchers. Several groups have reported the successful production of recombinant amelogenins but the production of recombinant amelogenin free of any tags, and at single band purity on silver stained SDS PAGE is technically challenging. This is important, as rigorous structure-function research frequently demands a high degree of protein purity and fidelity of protein sequence. Our aim was to generate His-tagged recombinant amelogenin at single band purity on silver stained SDS PAGE for use in functionality studies after His-tag cleavage. An acetic acid extraction technique (previously reported to produce recombinant amelogenin at 95% purity directly from E. coli followed by repeated rounds of nickel column affinity chromatography, failed to generate recombinant amelogenin at single band purity. This was because following an initial round of nickel column affinity chromatography, subsequent cleavage of the His-tag was not 100% efficient. A second round of nickel column affinity chromatography, used in attempts to separate the cleaved His-tag free recombinant from uncleaved His-tagged contaminants, was still unsatisfactory as cleaved recombinant amelogenin exhibited significant affinity for the nickel column. To solve this problem, we used preparative SDS PAGE to successfully purify cleaved recombinant amelogenins to single band purity on silver stained SDS PAGE. The resolving power of preparative SDS PAGE was such that His-tag based purification of recombinant amelogenin becomes redundant. We

    A facile hydrothermal route was developed for the preparation of well-aligned hierarchical flower-like NiO nanostructure with the assistance of SDS that served as a structure-directing agent as well as a capping agent in the process of aggregation and assembly. Notably, the NiO sensors exhibit enhanced gas-sensing performance towards ethanol, which could be explained in association with the ultrathin nanosheets that are close to Debye length (LD) scale and thus get the majority carriers fully depleted due to the ionization of adsorbed oxygen, abundant effective gas diffusion paths as well as high surface-to-volume ratio to promote sufficient contact and reaction between the NiO sample and ethanol molecules, and numerous miniature reaction rooms assembled with nanosheets to make the test gas molecules stay long enough for completed gas-sensing reactions. Besides, a novel growth mechanism with the passage of reaction time was also proposed in detail.

    Full Text Available Depression is a serious and potentially life-threatening mental disorder with unknown etiology. Emerging evidence shows that brain-derived neurotrophic factor (BDNF and microRNAs (miRNAs play critical roles in the etiology of depression. Here this study was aimed to identify and characterize the roles of BDNF and its putative regulatory miRNAs in depression. First, we identified that miR-182 may be a putative miRNA that regulates BDNF levels by bioinformatic studies, and characterized the effects of miR-182 on the BDNF levels using cell-based studies, side by side with miR-132 (a known miRNA that regulates BDNF expression. We showed that treatment of miR-132 and miR-182 respectively decreased the BDNF protein levels in a human neuronal cell model, supporting the regulatory roles of miR-132 and miR-182 on the BDNF expression. Furthermore, we explored the roles of miR-132 and miR-182 on the BDNF levels in depression using human subjects by assessing their serum levels. Compared with the healthy controls, patients with depression showed lower serum BDNF levels (via the enzyme-linked immunosorbent assays and higher serum miR-132 and miR-182 levels (via the real-time PCR. Finally, the Pearson's (or Spearman's correlation coefficient was calculated to study whether there was a relationship among the Self-Rating Depression Scale score, the serum BDNF levels, and serum BDNF-related miRNA levels. Our results revealed that there was a significant negative correlation between the SDS scores and the serum BDNF levels, and a positive correlation between the SDS scores and miR-132 levels. In addition, we found a reverse relationship between the serum BDNF levels and the miR-132/miR-182 levels in depression. Collectively, we provided evidence supporting that miR-182 is a putative BDNF-regulatory miRNA, and suggested that the serum BDNF and its related miRNAs may be utilized as important biomarkers in the diagnosis or as therapeutic targets of depression.

    Liu, Shuyan; Wu, Bin; Yang, Xiaoning

    2014-04-23

    A molecular dynamics simulation was conducted to study the structure and morphology of sodium dodecyl sulfate (SDS) surfactants adsorbed on a nanoscale graphene nanostructure in the presence of an electrolyte. The self-assembly structure can be reorganized by the electrolyte-induced effect. An increase in the ionic strength of the added electrolyte can enhance the stretching of adsorbed surfactants toward the bulk aqueous phase and make headgroups assemble densely, leading to a more compact structure of the SDS/graphene composite. The change in the self-assembly structure is attributed to the accumulation/condensation of electrolyte cations near the surfactant aggregate, consequently screening the electrostatic repulsion between charged headgroups. The role of the electrolyte revealed here provides direct microscopic evidence or an explanation of the reported experiments in the electrolyte tuning of the interfacial structure of a surfactant aggregate on the surface of carbon nanoparticles. Additionally, the buoyant density of the SDS/graphene assembly has been computed. With an increase in the ionic strength of the electrolyte, the buoyant density of the SDS/graphene composite rises. The interfacial accumulation of electrolytes provides an important contribution to the density enhancement. The study will be valuable for the dispersion and application of graphene nanomaterials.

  1. SDS interferes with SaeS signaling of Staphylococcus aureus independently of SaePQ.

    Directory of Open Access Journals (Sweden)

    Phuti E Makgotlho

    Full Text Available The Staphylococcus aureus regulatory saePQRS system controls the expression of numerous virulence factors, including extracellular adherence protein (Eap, which amongst others facilitates invasion of host cells. The saePQRS operon codes for 4 proteins: the histidine kinase SaeS, the response regulator SaeR, the lipoprotein SaeP and the transmembrane protein SaeQ. S. aureus strain Newman has a single amino acid substitution in the transmembrane domain of SaeS (L18P which results in constitutive kinase activity. SDS was shown to be one of the signals interfering with SaeS activity leading to inhibition of the sae target gene eap in strains with SaeS(L but causing activation in strains containing SaeS(P. Here, we analyzed the possible involvement of the SaeP protein and saePQ region in SDS-mediated sae/eap expression. We found that SaePQ is not needed for SDS-mediated SaeS signaling. Furthermore, we could show that SaeS activity is closely linked to the expression of Eap and the capacity to invade host cells in a number of clinical isolates. This suggests that SaeS activity might be directly modulated by structurally non-complex environmental signals, as SDS, which possibly altering its kinase/phosphatase activity.

    2014-02-15

    The thermal gelation of hydroxypropylmethylcellulose (HPMC) solutions has been studied as a function of sodium dodecyl sulfate (SDS) concentration with and without griseofulvin, a model particulate BCS Class II drug by rheological measurements of gelation temperature (Tgel), steady-state viscosity (η) at 25 °C, and ζ-potential. Polymer adsorption on the drug was demonstrated by a decrease in η and potential in the absence of SDS. Griseofulvin had a synergistic effect on gelation which was attributed to an effective spanning of associated hydrophobic polymeric regions through interactions with the adsorbed polymer. Adding SDS offsets this effect on Tgel shielding hydrophobic interactions. Higher SDS concentrations had no effect on the particles surface as evidenced by constant ζ-potential and Tgel. Yet, polymeric chains are saturated and larger surfactant aggregates account for the increase in viscosity. Understanding the gelation mechanism and complex interactions of HPMC with surfactants and drugs is necessary for the design of pharmaceutical products and optimization of their performance properties.

    The researchers studied differences in self-reported music experience and depression across ethnic groups, as well as differences in the relationship between music experience and depression across groups. College participants (78 African Americans, 111 Asian Americans, 218 Whites, and 87 in other ethnic groups) completed the Music Experience Questionnaire (MEQ) and the Center for Epidemiological Studies Depression scale. Statistically significant differences across groups were found on depression as well as on the MEQ factor for Subjective/Physical Reactions to music and on MEQ scales for Commitment to Music, Affective Reactions, Positive Psychotropic Effects, and Reactive Musical Behavior. A distinctive pattern of relationship was found between music variables and depression in the Asian American group, relative to the White and Other group. In particular, among Asian Americans there were negative correlations between depression and the MEQ Subjective/ Physical Reactions factor as well as the Affective Reactions scale. Implications were discussed for the literature on ethnicity and depression, music experience, and music therapy.

    2011-09-01

    Screening depressivity among adolescents is a key public health priority. In order to measure the severity of depressive symptomatology, a four-dimensional 20 items scale called "Center for Epidemiological Studies-Depression Scale" (CES-D) was developed. A shorter 10-item version was developed and validated (Andresen et al.). For this brief version, several authors supported a two-factor structure - Negative and Positive affect - but the relationship between the two reversed-worded items of the Positive affect factor could be better accounted for by correlated errors. The aim of this study is triple: firstly to test a French version of the CES-D10 among adolescents; secondly to test the relevance of a one-dimensional structure by considering error correlation for Positive affect items; finally to examine the extent to which this structural model is invariant across gender. The sample was composed of 269 French middle school adolescents (139 girls and 130 boys, mean age: 13.8, SD=0.65). Confirmatory Factorial Analyses (CFA) using the LISREL 8.52 were conducted in order to assess the adjustment to the data of three factor models: a one-factor model, a two-factor model (Positive and Negative affect) and a one-factor model with specification of correlated errors between the two reverse-worded items. Then, multigroup analysis was conducted to test the scale invariance for girls and boys. Internal consistency of the CES-D10 was satisfying for the adolescent sample (α=0.75). The best fitting model is the one-factor model with correlated errors between the two items of the previous Positive affect factor (χ(2)/dl=2.50; GFI=0.939; CFI=0.894; RMSEA=0.076). This model presented a better statistical fit to the data than the one-factor model without error correlation: χ(2)(diff) (1)=22.14, pfactor model with correlated errors was analyzed across separate samples of girls and boys. The model explains the data somewhat better for boys than for girls. The model's overall χ(2

    Efficient separation of mucins (200 kDa-2 MDa) was demonstrated using gradient SDS agarose/polyacrylamide composite gel electrophoresis (SDS-AgPAGE). Inclusion of urea (SDS-UAgPAGE) in the gels casting were shown to have no effect on the migration of mucins in the gel and allowed casting of gel at room temperature. This simplified the procedure for multiple casting of agarose polyacrylamide gradients and increased reproducibility of these gels. Hence, the implementation of urea makes the technique applicable for high throughput isolation and screening of mucin oligosaccharides by LC-MS after releasing the oligosaccharides from isolated, blotted mucin subpopulations. It was also shown that the urea addition had no effect on other supporting applications such as western and lectin blotting. In addition, identification of the mucin protein after tryptic digestion and LC-MS was possible and no protein carbamylation due to the presence of urea in the gel was detected. LC-MS software developed for metabolomic analysis was used for O-linked oligosaccharide detection and differential display of various mucin samples. Using this method, heterogeneous glycosylation of mucins and mucin-type molecules isolated by SDS-AgPAGE and SDS-UAgPAGE was shown to consist of more than 80 different components in a single band, and in the extreme cases, up to 300-500 components (MUC5B/AC from saliva and sputum and). Metabolomic software was also used to show that the migration of mucin isoforms within the gel is due to heterogeneous size distribution of the oligosaccharides, with the slower migrating bands enriched in high-molecular-weight oligosaccharides.

    Highlights: • To evaluate the integrity of the ITER tritium SDS bed, three kinds of assessments were conducted. • The structural analysis showed that the stress induced from the thermal load and the internal pressure is within the design stress intensity. • The combined fatigue and creep assessment was also performed according to the procedure of ASME code Subsection NH. • A new operation procedure to obtain more integrity margin was recommended. • The other operation procedure could be considered which makes the rapid operation possible giving up the marginal integrity. - Abstract: The primary vessel of ITER tritium SDS bed is made of stainless steel. It is heated beyond 500 °C to desorb tritium. During this process the primary vessel is subject to thermal stress. And it is also subject to thermal fatigue by the iterative process of absorption and desorption. In addition, its operation temperature range is in the thermal creep temperature region. Therefore, the tritium SDS bed should have sufficient design stress intensity under the high temperature operating conditions. It should also be free of damage due to fatigue during the design life. Thermal analysis and structural analysis was performed using a finite element method to calculate the temperature and the stress distribution of the ITER tritium SDS bed due to the internal pressure and thermal loads. The thermal fatigue and creep effects were also evaluated since the tritium SDS bed was heated to hot temperature region where creep occurs. Based on the distribution of the primary stress and secondary stress results, two evaluation cross-sections were selected. The evaluation showed that the calculated value on the cross-sections satisfied all of the limits of the design code requirements.

    Capillary electrophoresis is an important technique for the characterization of monoclonal antibodies (mAbs), especially in the pharmaceutical context. However, identification is difficult as upscaling and hyphenation of used methods directly to mass spectrometry is often not possible due to separation medium components that are incompatible with MS detection. Here a CE-MS method for the analysis of mAbs is presented analyzing SDS-complexed samples. To obtain narrow and intensive peaks of SDS-treated antibodies, an in-capillary strategy was developed based on the co-injection of positively charged surfactants and methanol as organic solvent. For samples containing 0.2% (v/v) of SDS, recovered MS peak intensities up to 97 and 95% were achieved using cetyltrimethylammonium bromide or benzalkonium chloride, respectively. Successful removal of SDS was shown in neutral coated capillaries but also in a capillary with a positively charged coating applying reversed polarity. The usefulness of this in-capillary strategy was demonstrated also for other proteins and for antibodies dissolved in up to 10% v/v SDS solution, and in other SDS-containing matrices, including the sieving matrix used in a standard CE-SDS method and gel-buffers applied in SDS-PAGE methods. The developed CE-MS approaches enable fast and reproducible characterization of SDS-complexed antibodies.

MÉTODO: Estudo transversal com 151 mulheres entre 40 e 65 anos de idade, usuárias de serviço de ginecologia geral em unidade de atenção básica à saúde no Rio de Janeiro. Aplicou-se a escala CES-D e um questionário estruturado para a obtenção de dados sociodemográficos, clínicos e ginecológicos. O nível de corte > 15 pontos na CES-D foi considerado como indicativo de quadro depressivo. RESULTADOS: A média de pontuação da amostra foi de 9,2 pontos (desvio padrão = 9,0. Os itens mais pontuados da escala foram relativos à insônia, tristeza e desânimo. Não houve associação significativa entre os escores e o período climatérico, características sociodemográficas, clínicas ou ginecológicas, exceto para as mulheres com presença de sintomas psíquicos, histórico depressivo pregresso e uso atual de antidepressivos (p = 0,000. Entre as 32 mulheres (21% com pontuação > 15 na CES-D, 72% referiram episódio depressivo pregresso. Dentre as participantes sem histórico depressivo, as perimenopáusicas apresentaram escores > 15 com maior freqüência. CONCLUSÃO: Essa casuística, oriunda de serviço não-especializado em menopausa ou saúde mental, revelou baixas pontuações médias na escala de sintomas depressivos CES-D, e o item insônia foi o mais pontuado. O histórico de depressão foi fator de associação com a alta pontuação na escala, mas não a fase climatérica em que a mulher se encontrava. A maior freqüência de pontuação acima do nível de corte nas mulheres sem histórico depressivo pregresso que estavam na perimenopausa sugere a maior vulnerabilidade, nessa fase, a episódios depressivos novos.INTRODUCTION: The objective of this study was to evaluate depressive symptoms in

    Full Text Available While there is evidence that the development and course of major depressive disorder (MDD symptomatology is associated with vascular disease, and that there are changes in energy utilization in the disorder, the extent to which cerebral blood flow is changed in this condition is not clear. This study utilized a novel imaging technique previously used in coronary and stroke patients, 320-slice Computed-Tomography (CT, to assess regional cerebral blood flow (rCBF in those with MDD and examine the pattern of regional cerebral perfusion. Thirty nine participants with depressive symptoms (Hamilton Depression Rating Scale 24 (HAMD24 score > 20, and Self-Rating Depression Scale (SDS score > 53 and 41 healthy volunteers were studied. For all subjects, 3 ml of venous blood was collected to assess hematological parameters. Transcranial Doppler (TCD ultrasound was utilized to measure parameters of cerebral artery rCBFV and analyse the Pulsatility Index (PI. 16 subjects (8 =  MDD; 8 =  healthy also had rCBF measured in different cerebral artery regions using 320-slice CT. Differences among groups were analyzed using ANOVA and Pearson's tests were employed in our statistical analyses. Compared with the control group, whole blood viscosity (including high\\middle\\low shear rateand hematocrit (HCT were significantly increased in the MDD group. PI values in different cerebral artery regions and parameters of rCBFV in the cerebral arteries were decreased in depressive participants, and there was a positive relationship between rCBFV and the corresponding vascular rCBF in both gray and white matter. rCBF of the left gray matter was lower than that of the right in MDD. Major depression is characterized by a wide range of CBF impairments and prominent changes in gray matter blood flow. 320-slice CT appears to be a valid and promising tool for measuring rCBF, and could thus be employed in psychiatric settings for biomarker and treatment response purposes.

    To investigate the relationship between traditional bullying, cyberbullying and depression in adolescents, with the involvement frequency and different roles considered. A stratified cluster sampling method was used to randomly select 5 726 middle school students in three cities of Anhui province in December 2013. Those students were surveyed by self-designed questionnaire of adolescent health-related behaviors in Anhui province. Self-reports on the general demographic information, physical, verbal, relational bullying and cyberbullying involvement and depression were collected. Additionally, the items assessing depression were based on Self-rating Depression Scale (SDS). The chi-square test used to compare prevalent rates of bullying involvement and depression in different groups of students with different demographic features. Multinomial logistic regressions were performed to explore the relationships between all four types of bullying and depression, after controlling confounders. We got a final effective sample of 5 726 student. The response rate was 99.4% in this study. Among 5 726 adolescents, the prevalence rates of bullying in the last two months were 23.4% (1 339/5 726) physically, 55.0% (3 147/5 726) verbally, 34.2% (1 958/5 726) socially, and 8.9% (512/5 726) electronically. The prevalence rate of depression was 64.8% (3 711/5 726). The detection rate was higher in participants who involved in physical, verbal, relational, and cyber bullying than those who not involved in bullying. After controlling the confounding factors, the different frequency and role of verbal and relational bullying were risk factors of depression (OR = 1.42-3.71, all P values bullying, except for occasional bully-victims (OR = 1.08, 95% CI: 0.79-1.49), others were more likely to be depressed than noninvolved students.

The present research aimed to search for validity evidences to Depression Scale (EDEP based on the relation to other variables assessing the same construct, depression, being also assessed by Beck Depression Inventory - BDI, and assessing related constructs, family support, measured by Perception of Family Support Inventory - IPSF. 157 undergraduates from a private university located in south state of Minas Gerais, 75,5% from female gender and 24,5% from male gender, aging from 18 to 51 years old (M=23,2; DP=6,4 took part in this study. At the results, high, significant and positive correlations were found between EDEP and BDI, as expected, indicating that the higher the scores on both scales, higher the depressive symptoms. As for the correlations between EDEP and IPSF dimensions, significant and negative correlations were found, suggesting that the higher depressive symptoms lower the perception of family support on individuals. Only marginally significant differences were found between genders, as to depressive symptoms (EDEP and BDI, indicating that women would score more at the depression scales.

    Full Text Available OBJECTIVES: Increasingly, medical research involves patients who complete outcomes in different languages. This occurs in countries with more than one common language, such as Canada (French/English or the United States (Spanish/English, as well as in international multi-centre collaborations, which are utilized frequently in rare diseases such as systemic sclerosis (SSc. In order to pool or compare outcomes, instruments should be measurement equivalent (invariant across cultural or linguistic groups. This study provides an example of how to assess cross-language measurement equivalence by comparing the Center for Epidemiologic Studies Depression (CES-D scale between English-speaking Canadian and Dutch SSc patients. METHODS: The CES-D was completed by 922 English-speaking Canadian and 213 Dutch SSc patients. Confirmatory factor analysis (CFA was used to assess the factor structure in both samples. The Multiple-Indicator Multiple-Cause (MIMIC model was utilized to assess the amount of differential item functioning (DIF. RESULTS: A two-factor model (positive and negative affect showed excellent fit in both samples. Statistically significant, but small-magnitude, DIF was found for 3 of 20 items on the CES-D. The English-speaking Canadian sample endorsed more feeling-related symptoms, whereas the Dutch sample endorsed more somatic/retarded activity symptoms. The overall estimate in depression scores between English and Dutch was not influenced substantively by DIF. CONCLUSIONS: CES-D scores from English-speaking Canadian and Dutch SSc patients can be compared and pooled without concern that measurement differences may substantively influence results. The importance of assessing cross-language measurement equivalence in rheumatology studies prior to pooling outcomes obtained in different languages should be emphasized.

    Full Text Available Depressive disorders are the most frequent psychiatric comorbidity in epilepsy but very often remain unrecognized and untreated. We examined 103 epileptic patients, aged 18-60 years, 40 males and 63 females, for the presence of interictal depressive disorder. All subjects underwent clinical psychiatric examination, including evaluation on Hamilton Depression Rating Scale (HAM-D-17. A questionnaire for demographic and seizure-related variables was also completed. Concurrent depressive disorder (clinically presented according to ICD-10 diagnostic criteria affected 28.3% of all evaluated patients. Based on HAM-D-17 scores depression was defined as mild - 80% of all depressed patients, moderate - 17% and severe - 3%. Atypical presentation of interictal depressive disorder was frequent. Depression has a tremendous effect on one’s family, social and psychological functioning, even more than the actual seizure frequency and severity. Diagnostic difficulties come through the atypical mode of presentation of depressive disorders in epilepsy. Proper neuropsychiatric evaluation is essential for improving treatment and quality of life for patients with epilepsy.

    Full Text Available Background and Objectives: Sodium dodecyl sulfate (SDS is one of the main surfactant components in detergents and cosmetics, used in high amounts as a detergent in products such as shampoos, car wash soap and toothpaste. Therefore, its bioremediation by suitable microorganisms is important. Alkylsulfatase is an enzyme that hydrolyses sulfate -ester bonds to give inorganic sulfate and alcohol. The purpose of this study was to isolate SDS–degrading bacteria from Tehran city car wash wastewater, study bacterial alkylsulfatase enzyme activity and identify the alkylsulfatase enzyme coding gene.Materials and Methods: Screening of SDS-degrading bacteria was carried out on basal salt medium containing SDS as the sole source of carbon. Amount of SDS degraded was assayed by methylene blue active substance (MBAS.Results and Conclusion: Identification of the sdsA gene was carried by PCR and subsequent sequencing of the 16S rDNA gene and biochemical tests identified Pseudomonas aeruginosa. This bacterium is able to degrade 84% of SDS after four days incubation. Bacteria isolated from car wash wastewater were shown to carry the sdsA gene (670bp and the alkylsulfatase enzyme specific activity expressed from this gene was determined to be 24.3 unit/mg . The results presented in this research indicate that Pseudomonas aeruginosa is a suitable candidate for SDS biodegradation.

    Full Text Available Genetic variation is prerequisite for plant breeding. Nothing information existed in the literature for available diversity of Coriander accession in Turkey. Plant breeding activities are negligible in Turkey. So in order to start effective plant breeding program in Turkey, information on the available genetic diversity is viable. Therefore we planned to study the genetic variation and population structure of 29 Coriander accessions by seed storage protein (SDS. SDS analysis elaborated the lack of population structure and genetic bottleneck in the Coriander accessions in Turkey. Based on the results of this study, it was clear that sampling strategy was not appropriate and plant introduction should be made from different sources and diverse genotypes should be used as parents to initialize the effective Turkish Coriander breeding program.

    Full Text Available Biofilms cause extensive damage to industrial settings. Thus, it is important to improve the existing techniques and develop new strategies to prevent bacterial biofilm formation. In the present study, we have prepared nanoporous polymer films from a self-assembled 1,2-polybutadiene-b-polydimethylsiloxane (1,2-PB-b-PDMS block copolymer via chemical cross-linking of the 1,2-PB block followed by quantitative removal of the PDMS block. Sodium dodecyl sulfate (SDS was loaded into the nanoporous 1,2-PB from aqueous solution. The SDS-loaded nanoporous polymer films were shown to block bacterial attachment in short-term (3 h and significantly reduce biofilm formation in long-term (1 week by gram-negative bacterium Escherichia coli. Tuning the thickness or surface morphology of the nanoporous polymer films allowed to extent the anti-biofilm capability.

    Sixteen isolates of Mycoplasma ovipneumoniae recovered from the nasal tract or lungs of sheep from different flocks in New Zealand were examined by bacterial restriction endonuclease DNA analysis (BRENDA) using EcoR1 and by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). All isolates gave BRENDA patterns which differed entirely from one another. Following 20 serial passages (corresponding to approximately 67 generations) of an isolate, no change was detected in the BRENDA pattern. When eight isolates were examined by SDS-PAGE most bands were common but, nevertheless, each isolate was unique in the sense that they differed from one another in one or more bands. The marked heterogeneity of patterns observed when strains of M. ovipneumoniae are compared by BRENDA, together with the stability of such patterns over many generations, will enable this approach to be used to study the epidemiology of individual strains of M. ovipneumoniae within a flock.

    Laryngectomy, a common treatment for laryngeal cancer, is a disabling operation that can induce tremendous stress, but little is known about how to alleviate the psychological effects of the operation. Compare the effectiveness of cognitive behavioral therapy (CBT) and medication in treating anxiety and depression among throat cancer patients after laryngectomy. Review of medical records of the psychological outpatient clinic in the Third People's Hospital of Huzhou City between March 2009 and May 2013 identified 63 patients with post-laryngectomy depression or anxiety disorders who received 8 weeks of one-on-one treatment with CBT (in which patients responded in writing because they were unable to speak) and 56 patients who received 8 weeks of treatment with buspirone (n=11), sertraline (n=9) or both busipirone and sertraline (n=36). The treatment provided (CBT or medications) was based on the stated preference of the patient. The Zung Self-rating Anxiety Scale (SAS) and the Zung Self-rating Depression Scale (SDS) were administered before and after treatment. After 8 weeks of treatment the mean SAS and SDS scores had decreased significantly in both groups and the prevalence of clinically significant anxiety and depression (based on SAS and SDS cutoff scores) had dropped dramatically. There were, however, no significant differences between the two treatment methods. In the medication group 32% of participants experienced one or more adverse reactions during treatment, but none of these were severe enough to require withdrawal from treatment. CBT is an effective, short-term treatment for reducing the anxiety and depressive symptoms that often occur after an individual is diagnosed with cancer or treated for cancer. There is robust evidence that treatment of these psychological symptoms can improve both the quality of life and course of illness in cancer patients, so oncologists and other clinicians need to regularly screen patients with cancer and other chronic life

    Full Text Available Hydrate-based separation experiments on simulate coal bed methane gas have been conducted in THF solution and SDS solution. In this work, a novel hydrate-based gas separation process was used to enhance CH4 separation from a 65.7% CH4/20.2% N2/O2 gas mixture in the presence of 300 ppm SDS and 19% THF solution. The characteristics of the CH4 separation efficiency, fluctuation of temperature, and pressure were studied at different promoter solution. It was found that hydrate formation was induced by promoter in the solution and occurred immediately as the experiments were started. THF performed better than SDS for CH4 separation from the CH4/N2/O2 gas mixture. In particular, the separation coefficients of CH4 and N2 were compared in two solutions. The gas mixture S.Fr. or CH4 recovery is increased from 1.056 to 1.259 while SF of N2 is decreased from 1.183 to 0.634 in THF solution.

  16. Inhibitory effect of post-micellar SDS concentration on thermal aggregation and activity of papain.

    2014-08-01

    Papain, a cysteine protease isolated from the latex of Carica papaya, is known to undergo irreversible thermal unfolding. In this study, we found that thermal unfolding of papain is accompanied by a simultaneous self-assembly process where this protein is observed to aggregate above 50°C. The extent of aggregation increased with increasing protein concentration from 3-40 µM. The aggregation was confirmed by enhanced turbidity, light scattering intensity, 1-anilino-8-naphthalene sulfonate (ANS) fluorescence intensity and by transmission electron microscopy. Furthermore, we noted that post-micellar concentration of sodium dodecyl sulfate (SDS) remarkably suppresses the thermal aggregation of papain. Far-UV circular dichroism studies revealed that SDS significantly enhances α-helical content of the protein and also tends to prevent its unfolding, and thus inhibits aggregation. Additionally, papain showed maximal activity at 65°C in neutral buffer. However, in the presence of 6 mM SDS (above its critical micellar concentration), the enzyme lost activity by about 10-fold. Thus, promoting the helical propensity of the protein does not appear to be a suitable strategy to overcome the aggregation related problems of industrially important proteins such as papain, which are not only required to be protected against aggregation but also need to remain functionally active in the presence of aggregation inhibitors.

    Full Text Available Abstract Kidney stone disease is a common health problem in industrialised nations. We developed a SDS-PAGE-based method to quantify Tamm Horsfall glycoprotein (THP for screening of kidney stone disease. Urinary proteins were extracted by using ammonium sulphate precipitation at 0.27 g salt/mL urine. The resulted pellet was dissolved in TSE buffer. Ten microliters of the urinary proteins extract was loaded and separated on 10% SDS-PAGE under reducing condition. THP migrated as single band in SDS-PAGE. The assay reproducibility and repeatability were 4.8% CV and 2.6% CV, respectively. A total of 117 healthy subjects and 58 stone patients were tested using this assay, and a distinct cut-off (P < 0.05 at 5.6 μg/mL THP concentration was used to distinguish stone patients from healthy subjects. The sensitivity and specificity of the method were 92.3% and 83.3%, respectively.

    The absorption and fluorescence spectral characteristics of some biologically active indoles have been studied as a function of acidity and basicity (H_/pH/H o) in cationic (cetyltrimethylammonium bromide, CTAB), anionic (sodium dodecylsulphate, SDS) and aqueous phases at a given surfactant concentration. The prototropic equilibrium reactions of these probes have been studied in aqueous and micellar phases and apparent excited state acidity constant (pKa*) values are calculated. The probes show formation of different species on changing pH. Various species present in water, CTAB and SDS have been identified and the equilibrium constants have been determined by Fluorimetric Titration method. The fluorescence spectral data suggest the formation of oxonium ion through the excited state proton transfer reaction in highly acidic media and formation of photoproducts due to the base catalyzed auto-oxidative reaction in basic aqueous solutions. Variations in the apparent pKa* value have been observed in different media. The change in the apparent p Ka values depends upon the solubilising power of the micelles, as well as on the location of the protonating site in the molecule. The observation about increase in pKa* values in SDS and decrease in CTAB compared to pure water for various equilibria is consistent with the pseudophase ion-exchange (PIE) model.

    The effect of sodium dodecyl sulphate (SDS) on the acid-base properties and on the solubility of a beta-blocker (pindolol) and of two benzodiazepines (diazepam and chlordiazepoxide) has been assessed. The study was performed by potentiometric and spectrophotometric determinations of the acidity constants and by spectrophotometric evaluation of the solubilities of the pharmaceutical drugs in aqueous solution and in solutions to which was added SDS with concentrations below and above the critical micelle concentration (cmc), at 25 degrees C and at an ionic strength 0.1 M (NaCl). The effect of the organized assemblies on the pKa values was quantified by the application of two theoretical models that differ in the inclusion of ionic exchange between positively charged species in solution. These models have allowed the determination of the binding constants for drug/micelle and yielded values in good agreement with those obtained by the solubility method, and in addition provide a more detailed picture of the effect of drug charge on its partition. The results can be taken to evidence different interaction modes of the drugs with the SDS micelles.

  20. Medium dependent dual turn on/turn off fluorescence sensing for Cu2 + ions using AMI/SDS assemblies

    Behavior of Amiloride (AMI) as a metal ion sensor in anionic surfactant assemblies of varying concentrations at different pH is depicted in this work. From a non-sensor fluorophore, AMI has been transformed in to a tunable fluorosensor for Cu2 + ions in various SDS concentrations. At premicellar concentration of SDS, ion-pair complex is expected to be formed between AMI and SDS due to electrostatic interactions between them. However at CMC concentrations of SDS, fluorescence intensity of AMI is greatly enhanced with red shift in emission, due to the incorporation of AMI molecule in the hydrophobic micellar interface. The behavior of metal sensing by AMI-SDS assemblies gives rise to several interesting observations. Micellation of SDS has been greatly enhanced by increasing copper ion concentrations, as these counter ions screens the charge on monomers of SDS which lead to the aggregation at premicellar concentrations only. Concentrations and pH dependent discrete trends of interactions between SDS-AMI and SDS-Cu2 + ions, have given tunable fluorescence responses (fluorescence turn on/turn off) of AMI for added Cu2 + ions. The electrostatic interaction between the metal cations and the anionic surfactants is the driving force for bringing the metal ions near to the vicinity of micelle where AMI resides. Thus, a comprehensive understanding of the mechanism related to the 'turn on-turn off' fluorescence response of AMI with respect to pH and SDS concentration for effective Cu2 + ion sensing is illustrated in this work.

    2002-01-01

    Full Text Available Diagnosing depression in stroke patients is a challenge in neuropsychiatry since depression symptoms may overlap neurological deficit signs. The best approach is to assess the presence of depressive symptoms using semi-structured or structured psychiatric interviews, such as the Present State Exam, the Structured Clinical Interview for DSM-IV or the Schedules for Clinical Assessment in Neuropsychiatry. The diagnosis of a depressive syndrome should be made according to standardized diagnostic criteria for mood disorders due to neurological disease such as in the DSM-IV or ICD-10. Depression rating scales such as the Hamilton Depression Scale and the Center for Epidemiologic Scales for Depression may be used to rate the depression severity and monitor the progression of antidepressant treatment. Most studies have reported the effectiveness of pharmacological treatment in patients with post-stroke depression, and there is preliminary evidence that the degree of impairment in activities of daily living (ADL may improve as well.

  5. A new hypothesis and exploratory model for the formation of large-scale inner-shelf sediment sorting and ``rippled scour depressions''

    2004-02-01

    Recent observations of inner continental shelves in many regions show numerous collections of relatively coarse sediment, which extend kilometers in the cross-shore direction and are on the order of 100 m wide. These "rippled scour depressions" have been interpreted to indicate concentrated cross-shelf currents. However, recent observations strongly suggest that they are associated with sediment transport along-shore rather than cross-shore. A new hypothesis for the origin of these features involves the large wave-generated ripples that form in the coarse material. Wave motions interacting with these large roughness elements generate near-bed turbulence that is greatly enhanced relative to that in other areas. This enhances entrainment and inhibits settling of fine material in an area dominated by coarse sediment. The fine sediment is then carried by mean currents past the coarse accumulations, and deposited where the bed is finer. We hypothesize that these interactions constitute a feedback tending to produce accumulations of fine material separated by self-perpetuating patches of coarse sediments. As with many types of self-organized bedforms, small features would interact as they migrate, leading to a better-organized, larger-scale pattern. As an initial test of this hypothesis, we use a numerical model treating the transport of coarse and fine sediment fractions, treated as functions of the local bed composition—a proxy for the presence of large roughness elements in coarse areas. Large-scale sorted patterns exhibiting the main characteristics of the natural features result robustly in the model, indicating that this new hypothesis offers a plausible explanation for the phenomena.

  6. Wording effects and the factor structure of the Hospital Anxiety & Depression Scale in HIV/AIDS patients on antiretroviral treatment in South Africa.

    Edwin Wouters

    Full Text Available BACKGROUND: Given the immense burden of HIV/AIDS on health systems in sub-Saharan Africa and the intricate link between HIV/AIDS and mental health problems, health care providers need a valid and reliable instrument to assess mental health rapidly. The Hospital Anxiety and Depression Scale (HADS may constitute such an instrument. The aims of this study were to: (1 examine the factor structure of the HADS in a population of South African HIV/AIDS patients on antiretroviral treatment (ART; and (2 identify and control the disturbing influence of systematic wording effects in vulnerable respondent groups. METHODOLOGY/PRINCIPAL FINDINGS: The translated scale was administered to 716 HIV/AIDS patients enrolled in the public sector ART program in South Africa. A combined confirmatory factor analysis and correlated-traits-correlated-methods framework was used to determine the preferred factor structure of the HADS, while controlling for the disturbing influence of systematic wording effects. When assessing the structure without a negative wording factor, all three factor structures displayed an acceptable fit to the data. The three-factor solution best fitted the data. Addition of a method factor significantly improved the fit of all three factor solutions. Using χ(2 difference testing, Razavi's one-factor solution displayed a superior fit compared to the other two factor solutions. CONCLUSIONS: The study outcomes support the use of the HADS as a valid and reliable means to screen for mental health problems in HIV/AIDS patients enrolled in a public-sector ART program in a resource-limited context. The results demonstrate the importance of evaluating and correcting for wording effects when examining the factor structure of the screening instrument in vulnerable patient groups. In light of the inter-relationships between HIV/AIDS and mental health problems and the scarcity of adequate screening tools, additional studies on this topic are required.

    Deficits in pro-social cooperation are common in many individuals with mental illnesses such as depression. For decades, researchers have used economic game paradigms to compare cross-cultural cooperative behavior. However, research using economic games to assess cooperative behavior in clinical populations is in the early stages. We hypothesized that individuals with greater depressive symptoms would struggle to maintain reciprocity in iterative games, but not in single-iteration games measuring personal values. Participants (n=41) played four computer-based economic games (prisoner's dilemma, the public goods game, the ultimatum game, and the trust game) measuring different aspects of cooperation. Participants completed the Depression Anxiety and Stress Scale (DASS) and other measures of personality and demographics. Analyses assessed the relationships between game performance and psychological distress as measured by the DASS. Significant correlations were found between game performance and depressive symptoms, but not symptoms of anxiety or stress. Performance in the prisoner's dilemma and public goods game was significantly related to depression in a linear regression even when known associations with depressive affect such as age, gender, race, education, marital status, and neuroticism were controlled for. Depressive symptoms were associated with an inability to sustain reciprocal cooperation. Participants showed the predicted deficits in cooperation in these economic games. Economic games show the potential for assessing the social deficits associated with depressive symptoms. © 2013 Elsevier B.V. All rights reserved.

    1984-01-01

    Several subjects who tell their depression and play a part of it in front of the doctor without being really depressed are reported. Some of them try to hide the symptoms (irritability or erethism, ceremonials of obsessive neurosis, shunning of phobia) which, in their opinion, might be detrimental to their reputation. Others neglect to describe some of the symptoms of their polymorphous clinical picture only underlining the depressive signs. Some others play a part of depression because they have believed to recognize themselves in persons presented by mass media, because it seems to them a duty to show an adequate depression in case of mournful event, or because they "convert" their problem into a depression. Some others use depression as a blackmail, or to obtain an advantage from doctor's conviction about their illness. The reason for the high frequency of similar cases in the present time are examined: the scientific divulgation and the acceptance of depression by the modern society are among the most important ones. The peculiar semantic vicissitudes of the word depression are also reviewed. A widening of the boundaries of depression has contributed to an increase in the number of the cases. Finally, in addition to patients who are depressed without being aware of it, the authors focus the inverse possibility: patients who believed or try to make their doctor believe (playing the part of depression in front of them) that they are depressed.

  18. SDS, a structural disruption score for assessment of missense variant deleteriousness

    Directory of Open Access Journals (Sweden)

    Thanawadee ePreeprem

    2014-04-01

    Full Text Available We have developed a novel structure-based evaluation for missense variants that explicitly models protein structure and amino acid properties to predict the likelihood that a variant disrupts protein function. A structural disruption score (SDS is introduced as a measure to depict the likelihood that a case variant is functional. The score is constructed using characteristics that distinguish between causal and neutral variants within a group of proteins. The SDS score is correlated with standard sequence-based deleteriousness, but shows promise for improving discrimination between neutral and causal variants at less conserved sites.The prediction was performed on 3-dimentional structures of 57 gene products whose homozygous SNPs were identified as case-exclusive variants in an exome sequencing study of epilepsy disorders. We contrasted the candidate epilepsy variants with scores for likely benign variants found in the EVS database, and for positive control variants in the same genes that are suspected to promote a range of diseases. To derive a characteristic profile of damaging SNPs, we transformed continuous scores into categorical variables based on the score distribution of each measurement, collected from all possible SNPs in this protein set, where extreme measures were assumed to be deleterious. A second epilepsy dataset was used to replicate the findings. Causal variants tend to receive higher sequence-based deleterious scores, induce larger physico-chemical changes between amino acid pairs, locate in protein domains, buried sites or on conserved protein surface clusters, and cause protein destabilization, relative to negative controls. These measures were agglomerated for each variant. A list of nine high-priority putative functional variants for epilepsy was generated. Our newly developed SDS protocol facilitates SNP prioritization for experimental validation.

    In this work, we evaluate the coupling constant and the form factors of the vertex J/ψDs using the techniques of the QCD sum rules. We consider all the three mesons off shell, resulting in three different form factors. However, despite the different form factors, when extrapolated to the pole of each off-shell meson, we find coupling constants that are in completely agreement each other. The result for the vertex J/ψDs coupling constant is gJ/ψD* sDs =4.30+0.42 -0.37GeV-1.

    Biochemical studies of the outermost spore layers of the Bacillus cereus family are hindered by difficulties in efficient dispersal of the external spore layers and difficulties in dissociating protein complexes that comprise the exosporium layer. Detergent and physical methods have been utilized to disrupt the exosporium layer. Herein we compare commonly used SDS extraction buffers used to extract spore proteins and demonstrate the incomplete extractability of the exosporium layer by these methods. Sonication and bead beating methods for exosporium layer removal were also examined. A combination of genetic and physical methods is the most effective for isolating proteins found in the spore exosporium. PMID:21338631

    The conventional "pump-and-treat" technology for subsurface remediation of groundwater contaminated with volatile organic compounds(VOCs) such as 1,1,1-trichloroethane(TCA), a common chlorinated organic solvent, has limitation of prohibitively long treatment time due to extremely low water solubility of the VOCs. Surfactant-based soil remediation has emerged as the effective technology that substantially reduces the treatment time. In order to make the whole process economical, the surfactant used in soil washing has to be recovered and reused. This study examined the recovery of anionic surfactant, sodium dodecyl sulfate (SDS), from soil remediation fluids containing TCA, using a bench-scale membrane pervaporation unit. The effects of high TCA concentration, surfactant dosage, and flow rate on permeation flux and selectivity( α value) of the process were evaluated. In general, higher surfactant concentration yielded lower TCA flux and constant water flux, resulting in declining α values; higher flow rate of TCA feed stream results in higher VOC flux and selectivity, an indication of the effect of concentration polarization; higher TCA feed concentration produces higher TCA permeation across the membrane, however, the selectivity was virtually unchanged unless the total TCA concentration exceeded 2000 ppm.

  9. Comparison Study of Flow in A Compound Channel: Experimental and Numerical Method Using Large Eddy Simulation SDS-2DH Model

    Full Text Available Flow modeling in a compound channel is a complex matter. Indeed, due to the smaller velocities in the floodplains than in the main channel, shear layers develop at the interfaces between two stage channels, and the channel conveyance is affected by a momentum transfer corresponding to this shear layer. Since a compound channel is characterized by a deep main channel flanked by relatively shallow flood plains, the interaction between the faster fluid velocities in the main channel and the slower moving flow on the floodplains causes shear stresses at their interface which significantly distort flow and boundary shear stress patterns. The distortion implies that flow field in rivers is highly non homogeneous turbulent, which lateral transport of fluid momentum and suspended sediment are influenced by the characteristics of flow in rivers. The nature of mechanism of lateral transport needs to be understood for the design of river engineering schemes that rely upon realistic flow. Furthermore, the flows in river are also almost turbulent. This means that the fluid motion is highly random, unsteady, and three-dimensional. Due to these complexities, the flow can not be properly predicted by using approximate analytical solutions to the governing equations of motion. With the complexity of the problems, the solution of turbulent is simplified with mathematics equation. The momentum transfer due to turbulent exchanges is then studied experimentally and numerically. Experimental data is obtained by using Electro Magnetic Velocimetry and Wave Height Gauge. The Large Eddy Simulation Sub Depth Scale (LES SDS-2 Dimensional Horizontal (2DH Model is used to solve the turbulent problem. Successive Over Relaxation (SOR method is employed to solve the numerical computation based ob finite difference discretization. The model has been applied to the compound channel with smooth roughness. Some organized large eddies were found in the boundary between main channel

    The stigma of major depressive disorder (MDD) is an important public health problem. This study evaluated stigma in MDD patients in China using explanatory model interview catalogue (EMIC) questionnaire and the demographic and clinical symptom factors associated with the stigma of these patients. A total of 158 MDD patients from domestic 3 mental health centers were surveyed. We used the EMIC questionnaire to assess stigma of these patients, Montgomery and Asberg depression rating scale (MADRS) to assess depressive severity, self-reporting inventory (SCL-90) to assess mental health level, Sheehan disability scale (SDS) to assess social function, and fatigue severity scale (FSS) to assess degree of fatigue. The stigma scores were significantly higher in the 18- to 30-year-old (z = 2.875, P = .024) and 31- to 40-year-old (z = 3.204, P = .008) groups than the 51- to 65-year-old group; in the full-time employment group than the retired group (z = 3.163, P = .016). The stigma scores exhibited significant negative correlation with age (r = -0.169, P = .034) but positive correlations with the scores of MADRS (r = .212, P = .007), total scores (r = .273, P = .001) and subscales of interpersonal sensitivity (r = .233, P = .003), depression (r = .336, P stigma. The age, employment status, fatigue, and depressive severity are closely associated with the perceived stigma of MDD patients and may be important factors considered for stigma interventions of MDD in China. © 2016 John Wiley & Sons Australia, Ltd.

Conclusion; Drug treatment in combination with psychotherapy is more effective for depression than sole drug treatment.

  14. Native SDS-PAGE: High Resolution Electrophoretic Separation of Proteins With Retention of Native Properties Including Bound Metal Ions

    Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is commonly used to obtain high resolution separation of complex mixtures of proteins. The method initially denatures the proteins that will undergo electrophoresis. Although covalent structural features of resolved proteins can be determined with SDS-PAGE, functional properties are destroyed, including the presence of non-covalently bound metal ions. To address this shortcoming, blue-native (BN)-PAGE has been introduced. This method retains functional properties but at the cost of protein resolving power. To address the need for a high resolution PAGE method that results in the separation of native proteins, experiments tested the impact of changing the conditions of SDS-PAGE on the quality of protein separation and retention of functional properties. Removal of SDS and EDTA from the sample buffer together with omission of a heating step had no effect on the results of PAGE. Reduction of SDS in the running buffer from 0.1% to 0.0375% together with deletion of EDTA also made little impact on the quality of the electrophoretograms of fractions of pig kidney (LLC-PK1) cell proteome in comparison with that achieved with the SDS-PAGE method. The modified conditions were called native (N)SDS-PAGE. Retention of Zn2+ bound in proteomic samples increased from 26 to 98% upon shifting from standard to modified conditions. Moreover, seven of nine model enzymes, including four Zn2+ proteins that were subjected to NSDS-PAGE retained activity. All nine were active in BN-PAGE, whereas all underwent denaturation during SDS-PAGE. Metal retention after electrophoresis was additionally confirmed using laser ablation-inductively coupled plasma-mass spectrometry and in-gel Zn-protein staining using the fluorophore TSQ.

    Molecular dynamics simulations of mixtures of sodium dodecyl sulfate (SDS) and 1-dodecanol molecules on a graphite surface were carried out at low and high concentration to investigate the formation of aggregates on the solid plate. The simulations showed that at low concentration the surfactants were well adsorbed on the surface by forming layers structures or a hemicylinder aggregate for a slightly higher surfactant concentration whereas at the highest concentration the surfactants formed monolayer-like structures localized away from the graphite surface with a water bin between the monolayer and the graphite plate. Therefore, we obtained different arrays of those observed in recent simulations of pure SDS adsorbed on graphite at the same concentration reported in the literature. The unexpected water layer between the 1-dodecanol and the graphite surface, at the highest concentration, was explained in terms of the Hamaker constants. The present results suggest that the formation of aggregates on solid surfaces is a combined effect not only of the surfactant-surfactant and the surfactant-wall interactions but also of the surfactant concentration.

    Full Text Available Crude protein separation was carried out for Corchorus incisifolious, Corchorus aestuans, Corchorus tridens and Corchorus olitorious using Sodium Dodecyl Sulphate-Polyacrylamide Gel Electrophoresis (SDS-PAGE. Plants were collected both from wild and cultivated sites and samples included leaves and seeds for the electrophoretic study. Distinct polymorphism in electrophoretic banding patterns of seed and leaf proteins following SDS- PAGE was observed in the four Corchorus species studied. Forty- two polypeptide bands were observed in the seed and a total of eleven polypeptide bands were observed in the leaves of the Corchorus species studied. The electrophoretic study revealed protein bands with various intensities ranging from high, to low and faint. The results showed that there was variation in both the seed and leaf proteins of the Corchorus species studied. A dendrogram constructed based on the Single Linkage Cluster Analysis (SLCA clustering method revealed three major clusters for seeds. Cluster I consisted of C. incisifolious and C. aestuans, cluster II consisted of C. tridens, while cluster III consisted of C. olitorious. The leaf protein extracts were grouped into two clusters, cluster one containing C. incisifolious and C. aestuans, while the other contained C. tridens and C. olitorious.

    To evaluate the effects of levomilnacipran extended-release (LVM-ER; 40-120mg/day) on noradrenergic (NA) and anxiety-related symptoms in adults with major depressive disorder (MDD) and explore the relationship between these symptoms and functional impairment. Data were pooled from 5 randomized, double-blind, placebo-controlled trials (N=2598). Anxiety and NA Cluster scores were developed by adding selected item scores from the Montgomery-Åsberg Depression Rating Scale (MADRS) and 17-item Hamilton Depression Rating Scale (HAMD17). A path analysis was conducted to estimate the direct effects of LVM-ER on functional impairment (Sheehan Disability Scale [SDS] total score) and the indirect effects through changes in NA and Anxiety Cluster scores. Mean improvements from baseline in NA and Anxiety Cluster scores were significantly greater with LVM-ER versus placebo (both PAnxiety Cluster (39% vs 36%; odds ratio=1.19; P=0.041). Mean improvement in SDS total score was also significantly greater with LVM-ER versus placebo (-7.3 vs -5.6; PAnxiety Cluster score change (18%); the direct effect was negligible. NA and Anxiety Cluster scores, developed based on the face validity of individual MADRS and HAMD17 items, were not predefined as efficacy outcomes in any of the studies. In adults with MDD, LVM-ER indirectly improved functional impairment mainly through improvements in NA symptoms and less so via anxiety symptoms. Copyright © 2016 The Authors.

    Fragmentation of monoclonal antibodies is a critical quality attribute routinely monitored to assess the purity and integrity of the product from development to commercialization. Cleavage in the upper hinge region of IgG1 monoclonal antibodies is a common fragmentation pattern widely studied by size exclusion chromatography (SEC). Capillary electrophoresis with sodium dodecylsulfate (CE-SDS) is a well-established technique commonly used for monitoring antibody fragments as well, but its comparability to SEC in monitoring hinge fragments has not been established until now. We report a characterization strategy that establishes the correlation between hinge region fragments analyzed by SEC and CE-SDS. Monoclonal antibodies with elevated hinge fragments were generated under low pH stress conditions and analyzed by SEC and CE-SDS. The masses of the fragments generated were determined by LC-MS. Electrophoretic migration of the hinge fragmentation products in CE-SDS were determined based on their mass values. Comparative assessment of fragments by SEC, and CE-SDS showed similar correlation with incubation time. This study demonstrates that CE-SDS can be employed as a surrogate technique to SEC for monitoring hinge region fragments. Most importantly, combination of these techniques can be used to obtain comprehensive understanding of fragment related characteristics of therapeutic protein products. Copyright © 2017 Elsevier B.V.

    2008-02-21

    The aggregate structure of sodium dodecyl sulfate (SDS) adsorbed at the graphite-water interface has been studied with the aid of molecular dynamics (MD) simulations. As expected, our results show that adsorbed SDS yields hemi-cylindrical micelles. The hemi-cylindrical aggregates in our simulations closely resemble all structural and morphological details provided by previous solution atomic force microscopy (AFM) experiments. More interestingly, our data indicate that SDS head groups do not provide a complete shield to the hydrophobic tails. Instead, we found regions in which the hydrophobic tails are exposed to the aqueous solution. By conducting a parametric study for SDS-like nonionic surfactants we show that electrostatic interactions between SDS head groups and counterions are responsible for the unexpected result. Our interpretation is corroborated by density profiles, analysis of the coordination states, and mean square displacement data for both the adsorbed SDS surfactants and the counterions in solution. Counterion condensation appears to be a physical phenomenon that could be exploited to direct the assembly of advanced nanostructured materials.

    Copper-surfactant wastewaters are often encountered in electroplating, printed circuit boards manufacturing, and metal finishing industries, as well as in retentates from micellar-enhanced ultrafiltration process. A low-cost three-dimensional steel wool cathode reactor was evaluated for electrolytic recovery of Cu ion from dilute copper solution (0.2 mM) in the presence of sodium dodecyl sulfate (SDS), octylphenol poly (ethyleneglycol) 9.5 ether (TX), nonylphenol poly (oxyethylene) 9 ether (NP9) and polyoxyethylene (20) sorbitan monooleate (TW) and also mixed surfactants (anionic/nonionic). The reactor showed excellent copper recovery ability in comparison to a parallel-plate reactor. The reactor rapidly recovered copper with a reasonable current efficiency. 93% of copper was recovered at current density of 1 A m{sup -2} and pH 4 in the presence of 8.5 mM SDS.
