A high-throughput screening system for homogeneous catalyst discovery has been developed by integrating a continuous-flow capillary-based microreactor with ultra-high pressure liquid chromatography (UHPLC) for fast online analysis. Reactions are conducted in distinct and stable zones in a flow stream that allows for time and temperature regulation. UHPLC detection at high temperature allows high throughput online determination of substrate, product, and byproduct concentrations. We evaluated the efficacies of a series of soluble acid catalysts for an intramolecular Friedel-Crafts addition into an acyliminium ion intermediate within one day and with minimal material investment. The effects of catalyst loading, reaction time, and reaction temperature were also screened. This system exhibited high reproducibility for high-throughput catalyst screening and allowed several acid catalysts for the reaction to be identified. Major side products from the reactions were determined through off-line mass spectrometric detection. Er(OTf)3, the catalyst that showed optimal efficiency in the screening, was shown to be effective at promoting the cyclization reaction on a preparative scale. PMID:20666502

2006-03-01

Several similarity laws for the collisionless interaction of ultra-intense electromagnetic fields with a plasma of an arbitrary initial shape are presented. Both ultra-relativistic and non-relativistic cases are covered. The ion motion is included. A relation to the S-similarity described in Pukhov et al (2004 Plasma Phys. Control. Fusion 46 B179) and Gordienko and Pukhov (2005 Phys. Plasmas 12 043109) is established. A brief discussion of possible ways of experimental verification of scaling laws is presented. The results can be of interest for experiments and numerical simulations in the areas of ion acceleration, harmonic generation, magnetic field generation and Coulomb explosion of clusters.

Background: Robust evidence supports the effectiveness of screening and brief alcohol interventions in primary healthcare. However, lack of understanding about their “active ingredients” and concerns over the extent to which current approaches remain faithful to their original theoretical roots has led some to demand a cautious approach to future roll-out pending further research. Against this background, this paper provides a timely overview of the development of the brief alcohol intervention evidence base to assess the extent to which it has achieved the four key levels of intervention research: efficacy, effectiveness, implementation, and demonstration. Methods: Narrative overview based on (1) the results of a review of systematic reviews and meta-analyses of the effectiveness of brief alcohol intervention in primary healthcare and (2) synthesis of the findings of key additional primary studies on the improvement and evaluation of brief alcohol intervention implementation in routine primary healthcare. Results: The brief intervention field seems to constitute an almost perfect example of the evaluation of a complex intervention. Early evaluations of screening and brief intervention approaches included more tightly controlled efficacy trials and have been followed by more pragmatic trials of effectiveness in routine clinical practice. Most recently, attention has shifted to dissemination, implementation, and wider-scale roll-out. However, delivery in routine primary health remains inconsistent, with an identified knowledge gap around how to successfully embed brief alcohol intervention approaches in mainstream care, and as yet unanswered questions concerning what specific intervention component prompt the positive changes in alcohol consumption. Conclusion: Both the efficacy and effectiveness of brief alcohol interventions have been comprehensively demonstrated, and intervention effects seem replicable and stable over time, and across different study contexts. Thus, while unanswered questions remain, given the positive evidence amassed to date, research efforts should maintain a continued focus on promoting sustained implementation of screening and brief alcohol intervention approaches in primary care to ensure that those who might benefit from screening and brief alcohol interventions actually receive such support.

2010-01-01

High dimensional statistical problems arise from diverse fields of scientific research and technological development. Variable selection plays a pivotal role in contemporary statistical learning and scientific discoveries. The traditional idea of best subset selection methods, which can be regarded as a specific form of penalized likelihood, is computationally too expensive for many modern statistical applications. Other forms of penalized likelihood methods have been successfully developed over the last decade to cope with high dimensionality. They have been widely applied for simultaneously selecting important variables and estimating their effects in high dimensional statistical inference. In this article, we present a brief account of the recent developments of theory, methods, and implementations for high dimensional variable selection. What limits of the dimensionality such methods can handle, what the role of penalty functions is, and what the statistical properties are rapidly drive the advances of the field. The properties of non-concave penalized likelihood and its roles in high dimensional statistical modeling are emphasized. We also review some recent advances in ultra-high dimensional variable selection, with emphasis on independence screening and two-scale methods. PMID:21572976

Abstract Background Drinking alcohol during pregnancy has a range of negative consequences for the developing fetus. Screening and brief intervention approaches have significant promise, but their population impact may be limited by a range of challenges to implementation. We, therefore, conducted preliminary acceptability and feasibility evaluation of a computer-delivered brief intervention for alcohol use during pregnancy. Methods Participants were 50 pregnant women who screened positive for risky drinking during a routine prenatal clinic visit and were randomly assigned to computer-delivered brief intervention or assessment-only conditions. Results Ratings of intervention ease of use, helpfulness, and other factors were high (4.7–5.0 on a 1–5 scale). Participants in both conditions significantly decreased alcohol use at follow-up, with no group differences; however, birth weights for infants born to women in the intervention group were significantly higher (p<0.05, d = 0.62). Conclusions Further development and study of computer-delivered screening and intervention for alcohol use during pregnancy are warranted. PMID:21823917

2017-01-01

The Generalized Anxiety Disorder scale (GAD-7) is one of the most frequently used diagnostic self-report scales for screening, diagnosis and severity assessment of anxiety disorder. Its psychometric properties from the view of the Item Response Theory paradigm have rarely been investigated. We aimed to close this gap by analyzing the GAD-7 within a large sample of primary care patients with respect to its psychometric properties and its implications for scoring using Item Response Theory. Robust, nonparametric statistics were used to check unidimensionality of the GAD-7. A graded response model was fitted using a Bayesian approach. The model fit was evaluated using posterior predictive p-values, item information functions were derived and optimal predictions of anxiety were calculated. The sample included N = 3404 primary care patients (60% female; mean age, 52,2; standard deviation 19.2) The analysis indicated no deviations of the GAD-7 scale from unidimensionality and a decent fit of a graded response model. The commonly suggested ultra-brief measure consisting of the first two items, the GAD-2, was supported by item information analysis. The first four items discriminated better than the last three items with respect to latent anxiety. The information provided by the first four items should be weighted more heavily. Moreover, estimates corresponding to low to moderate levels of anxiety show greater variability. The psychometric validity of the GAD-2 was supported by our analysis.

Electroconvulsive therapy (ECT) has demonstrated efficacy in treating core symptoms of Parkinson's disease (PD); however, widespread use of ECT in PD has been limited due to concern over cognitive burden. We investigated the use of a newer ECT technology known to have fewer cognitive side effects (right unilateral [RUL] ultra-brief pulse [UBP]) for the treatment of medically refractory psychiatric dysfunction in PD. This open-label pilot study included 6 patients who were assessed in the motoric, cognitive, and neuropsychiatric domains prior to and after RUL UBP ECT. Primary endpoints were changes in total score on the HAM-D-17 and GDS-30 rating scales. Patients were found to improve in motoric and psychiatric domains following RUL UBP ECT without cognitive side effects, both immediately following ECT and at 1-month follow-up. This study demonstrates that RUL UBP ECT is safe, feasible, and potentially efficacious in treating multiple domains of PD, including motor and mood, without clear cognitive side effects. © 2016 John Wiley & Sons A/S.

Bystander compression-only cardiopulmonary resuscitation (CPR) improves survival after out-of-hospital cardiac arrest. To broaden CPR training, 1-2min ultra-brief videos have been disseminated via the Internet and television. Our objective was to determine whether participants passively exposed to a televised ultra-brief video perform CPR better than unexposed controls. This before-and-after study was conducted with non-patients in an urban Emergency Department waiting room. The intervention was an ultra-brief CPR training video displayed via closed-circuit television 3-6 times/hour. Participants were unaware of the study and not told to watch the video. Pre-intervention, no video was displayed. Participants were asked to demonstrate compression-only CPR on a manikin. Performance was scored based on critical actions: check for responsiveness, call for help, begin compressions immediately, and correct hand placement, compression rate and depth. The primary outcome was the proportion of participants who performed all actions correctly. There were 50 control and 50 exposed participants. Mean age was 37, 51% were African-American, 52% were female, and 10% self-reported current CPR certification. There were no statistically significant differences in baseline characteristics between groups. The number of participants who performed all actions correctly was 0 (0%) control vs. 10 (20%) exposed (difference 20%, 95% confidence interval [CI] 8.9-31.1%, p<0.001). Correct compression rate and depth were 11 (22%) control vs. 22 (44%) exposed (22%, 95% CI 4.1-39.9%, p=0.019), and 5 (10%) control vs. 15 (30%) exposed (20%, 95% CI 4.8-35.2%, p=0.012), respectively. Passive ultra-brief video training is associated with improved performance of compression-only CPR. Copyright © 2017 Elsevier B.V. All rights reserved.

The Galactic Magnetic Field is a peeving and importune screen between Ultra-High Energy Cosmic Rays and us cosmologists, engaged in the combat to unveil their properties and origin, as it deviates their paths towards the Earth in unpredictable ways. I will, in this order: briefly review the available field models on the market; explain a little trick which allows one to obtain cosmic rays deflection variances without even knowing what the (random) GMF model is; and argue that there is a lack of anisotropy in the large scales cosmic rays signal, which the Galactic field can do nothing about.

Antiapoptotic Bcl-2 family proteins are validated cancer targets composed of six related proteins. From a drug discovery perspective, these are challenging targets that exert their cellular functions through protein-protein interactions (PPIs). Although several isoform-selective inhibitors have been developed using structure-based design or high-throughput screening (HTS) of synthetic chemical libraries, no large-scale screen of natural product collections has been reported. A competitive displacement fluorescence polarization (FP) screen of nearly 150,000 natural product extracts was conducted against all six antiapoptotic Bcl-2 family proteins using fluorochrome-conjugated peptide ligands that mimic functionally relevant PPIs. The screens were conducted in 1536-well format and displayed satisfactory overall HTS statistics, with Z'-factor values ranging from 0.72 to 0.83 and a hit confirmation rate between 16% and 64%. Confirmed active extracts were orthogonally tested in a luminescent assay for caspase-3/7 activation in tumor cells. Active extracts were resupplied, and effort toward the isolation of pure active components was initiated through iterative bioassay-guided fractionation. Several previously described altertoxins were isolated from a microbial source, and the pure compounds demonstrate activity in both Bcl-2 FP and caspase cellular assays. The studies demonstrate the feasibility of ultra-high-throughput screening using natural product sources and highlight some of the challenges associated with this approach. © 2014 Society for Laboratory Automation and Screening.

Brief depression screening questionnaires may increase detection of depression in primary care settings but there have been few validation studies carried out in typical populations in low-income countries. Cultural validation of the Patient Health Questionnaire (PHQ-9/PHQ-2), the 20-item Self-Reporting Questionnaire (SRQ-20) and the Kessler scales (K6/K10) was carried out in 306 adults consecutively attending primary care facilities in small towns in Ethiopia. To assess criterion validity, the gold standard assessment for presence of Major Depressive Disorder (MDD) was made by Ethiopian psychiatric nurses using the Mini International Neuropsychiatric Interview. The prevalence of gold standard MDD was 5.9%, with irritability more common than depressed mood or anhedonia. The area under the receiver operating characteristic curve indicated good performance of the PHQ-9, SRQ-20, K6 and K10 (0.83-0.85) but only fair for the PHQ-2 (0.78). No cut-off score had acceptable sensitivity combined with adequate positive predictive value. All screening questionnaires were associated with disability and the PHQ-9 and SRQ-20 were associated with higher health service contacts, indicating convergent validity. Construct validity of all scales was indicated by unidimensionality on exploratory factor analysis. Test-retest reliability was not assessed. Brief depression screening questionnaires were found to be valid in primary care in this low-income country. However, these questionnaires do not have immediate applicability in routine clinical settings. Further studies should evaluate utility of indicated screening embedded within health system changes that support MDD detection. Investigation of irritability as a core depression symptom is warranted. Copyright © 2015 Elsevier B.V. All rights reserved.

The Brief Early Childhood Screening Assessment: Preliminary Validity in Pediatric Primary Care.

Fallucco, Elise M; Wysocki, Tim; James, Lauren; Kozikowski, Chelsea; Williams, Andre; Gleason, Mary M

Brief, well-validated instruments are needed to facilitate screening for early childhood behavioral and emotional problems (BEPs). The objectives of this study were to empirically reduce the length of the Early Childhood Screening Assessment (ECSA) and to assess the validity and reliability of this shorter tool. Using caregiver ECSA responses for 2467 children aged 36 to 60 months seen in primary care, individual ECSA items were ranked on a scale ranging from "absolutely retain" to "absolutely delete." Items were deleted sequentially beginning with "absolutely delete" and going up the item prioritization list, resulting in 35 shorter versions of the ECSA. A separate primary care sample (n = 69) of mothers of children aged 18 to 60 months was used to determine the sensitivity and specificity of each shorter ECSA version using psychiatric diagnosis on the Diagnostic Infant and Preschool Assessment as the gold standard. The version with the optimal balance of sensitivity, specificity, and length was selected as the Brief ECSA. Associations between Brief ECSA scores and other pertinent measures were evaluated to estimate reliability and validity. A 22-item measure reflected the best combination of brevity, sensitivity and specificity. A cutoff score of 9 or higher on the 22-item Brief ECSA demonstrated acceptable sensitivity (89%) and specificity (85%) for predicting a psychiatric diagnosis. Brief ECSA scores correlated significantly and in expected directions with scores on pertinent measures and with demographic variables. The results indicate that the Brief ECSA has sound psychometric properties for identifying young children with BEPs in primary care.

Depression is a serious psychological problem in the palliative care setting. Brief screening tools for depression are lacking and need to be brief and acceptable. This study aimed to identify the properties of the single Portuguese question "Está deprimido?" ("Are you depressed?") to screen for depression. Retrospective study from 100 patient's medical records identifying the answers on the single Portuguese question for depression "Está deprimido?" ("Are you depressed?") and the HADS depression sub-scale, using a score ≥11 on the latter as the gold standard for clinically significant depressive symptoms. Sensitivity, specificity, positive predictive and negative values were calculated. Response rate for the single Portuguese question for depression was 100%. Prevalence of depression symptoms (HADS-d ≥ 11) was 43%. To the question "Está deprimido?" 60 patients responded "yes." Sixteen patients who replied "no" to the single question had clinically significant depressive symptoms based on the HADS depression sub-scale. The single tool had 65.2% sensitivity, 49.2% specificity and 50.0% and 64.4% of positive predictive and negative values, respectively. In this first preliminary retrospective Portuguese study, the single question for depression has shown poor screening properties. Future research in larger and mixed patientś samples of Portuguese terminally ill is necessary to find more accurate and robust properties of this brief tool.

There is a need for brief, accurate screening when assessing multiple mental disorders. Two-stage hierarchical screening, consisting of brief pre-screening followed by a battery of disorder-specific scales for those who meet diagnostic criteria, may increase the efficiency of screening without sacrificing precision. This study tested whether more efficient screening could be gained using two-stage hierarchical screening than by administering multiple separate tests. Two Australian adult samples (N=1990) with high rates of psychopathology were recruited using Facebook advertising to examine four methods of hierarchical screening for four mental disorders: major depressive disorder, generalised anxiety disorder, panic disorder and social phobia. Using K6 scores to determine whether full screening was required did not increase screening efficiency. However, pre-screening based on two decision tree approaches or item gating led to considerable reductions in the mean number of items presented per disorder screened, with estimated item reductions of up to 54%. The sensitivity of these hierarchical methods approached 100% relative to the full screening battery. Further testing of the hierarchical screening approach based on clinical criteria and in other samples is warranted. The results demonstrate that a two-phase hierarchical approach to screening multiple mental disorders leads to considerable increases efficiency gains without reducing accuracy. Screening programs should take advantage of prescreeners based on gating items or decision trees to reduce the burden on respondents. © 2013 Elsevier B.V. All rights reserved.

The Palomar Transient Factory (PTF) and its successor, the intermediate PTF (iPTF), are wide-field synoptic sky surveys aimed to detect transients. Even though the main science goal for PTF/iPTF is to detect various types of transients, the synoptic nature of the surveys can also be used for the study of variable stars. In this proceedings contribution, I will first give a brief introduction to PTF/iPTF, followed by the two pulsating stars studies using the PTF/iPTF data: the Ultra-Long Period Cepheids (ULPC) in M31 and the RR Lyrae in the Kepler field. For the formal study, we searched the M31's ULPC using PTF imaging data, and follow up the candidates with other telescopes. Our finding revealed that there are only two ULPC in M31. I will give a brief implication of our finding in distance scale studies. For the latter study, I will present our work on the derivation of metallicity-light curve relation in native PTF/iPTF R-band using the RRab stars in the Kepler field.

The objective of this study was to evaluate the integration of a screening, brief intervention, and referral to treatment (SBIRT) curriculum for alcohol and other drug use into a pediatric residency program. Pediatric and medicine/pediatric residents in an adolescent medicine rotation located in an urban teaching hospital participated in the study. Main outcome measures were pre- and post-training knowledge scores, performance of the Brief Negotiation Interview (BNI), training satisfaction, and adoption of the BNI into clinical practice. Thirty-four residents were trained. Significant pre- to post-training improvements were seen in knowledge scores (P < .001) and performance as measured by the BNI Adherence Scale (P < .001). Residents reported high satisfaction immediately post-training and at 30 days on a 1-5 Likert scale: mean 1.41 to 1.59 (1 = very satisfied) (P = 0.23). Over a 9-month period, 53% of residents documented performing at least 1 BNI, of which 2/3 reported ≥2 BNIs in a subsequent clinical setting. The results show that integrating a SBIRT curriculum into a pediatric residency program increases residents' knowledge and skills.

Active extracts were resupplied and effort toward the isolation of pure active components was initiated through iterative bioassay-guided fractionation. Several previously described altertoxins were isolated from a microbial source and the pure compounds demonstrate activity in both Bcl-2 FP and caspase cellular assays. The studies demonstrate the feasibility of ultra high throughput screening using natural product sources and highlight some of the challenges associated with this approach. PMID:24870016

2011-01-01

This study evaluated the internal structure and convergent and discriminant evidence for the Colorado Learning Difficulties Questionnaire (CLDQ), a 20-item parent-report rating scale that was developed to provide a brief screening measure for learning difficulties. CLDQ ratings were obtained from parents of children in two large community samples and two samples from clinics that specialize in the assessment of learning disabilities and related disorders (total N = 8,004). Exploratory and confirmatory factor analyses revealed five correlated but separable dimensions that were labeled reading, math, social cognition, social anxiety, and spatial difficulties. Results revealed strong convergent and discriminant evidence for the CLDQ Reading scale, suggesting that this scale may provide a useful method to screen for reading difficulties in both research studies and clinical settings. Results are also promising for the other four CLDQ scales, but additional research is needed to refine each of these measures. PMID:21574721

The cognitive side-effects of bifrontal (BF) and right unilateral (UL) ultra-brief pulse (0.3 ms) electroconvulsive therapy (ECT) were compared, in the treatment of patients with a depressive episode. Neuropsychological functioning in patients with a medication refractory depressive episode, that were treated with a course of BF ultra-brief ECT at 1.5 times seizure threshold (ST) or UL ultra-brief ECT at 6 times ST, by random assignment, was assessed before treatment, and 1 and 6 weeks after the treatment course, by a blinded rater. Of the 64 patients that were included, 32 (50%) received BF ECT, and 32 (50%) received UL ECT, by random assignment. Neuropsychological testing 1 and 6 weeks after treatment was performed by 30 (93.75%) and 19 (59.37%) patients, respectively, in the BF-group and 29 (90.62%) and 20 (62.50%), respectively, in the UL-group. There was no deterioration in any of the neuropsychological measures. Patients rated their memory as clearly improved after treatment. There were no significant differences between the patients given BF ECT and those given UL ECT. Ultrabrief pulse ECT, used either in combination with a UL electrode position and a stimulus of 6 times ST, or a BF electrode position with a stimulus of 1.5 times ST, are effective antidepressant techniques, that do not have a deleterious effect on cognitive function.

Depression and anxiety are some of the most common causes of morbidity, social dysfunction, and reduced academic performance in college students. The combination of improved surveillance and access to care would result in better outreach. Brief screening tools can help reach larger populations of college students efficiently. However, reliability and validity of brief screeners for anxiety and depression have not been assessed in college students. Thus, the purpose of this study was to assess in a sample of college students the psychometric properties of PHQ-4, a brief screening tool for depression and anxiety. Undergraduate students were recruited from general education classes at a Midwestern university. Students were given a questionnaire that asked them whether they had been diagnosed by a doctor or health professional with anxiety or depression. Next, they were asked to respond to the items on the PHQ-4 scale. A total of 934 students responded to the survey (response rate=72%). Majority of the participants were females (63%) and Whites (80%). The internal reliability of PHQ-4 was found to be high (α=0.81). Those who were diagnosed with depression or anxiety had statistically significantly higher scores on PHQ-4 (p<0.01). Corrected item total correlations for PHQ-4 were between r=0.66 and r=0.80. PHQ-4 operating characteristics were estimated and area under the curve (AUC) values were 0.835 and 0.787, respectively for anxiety and depression. The PHQ-4 is a reliable and valid tool that can serve as a mass screener for depression and anxiety in young adults. Widespread implementation of this screening tool should be explored across college campuses. Copyright © 2016 Elsevier Inc. All rights reserved.

Personality disorder (PD) is associated with significant functional impairment and an elevated risk of violent and suicidal behaviour. The prevalence of PD in populations of young offenders is likely to be high. However, because the assessment of PD is time-consuming, it is not routinely assessed in this population. A brief screen for the identification of young people who might warrant further detailed assessment of PD could be particularly valuable for clinicians and researchers working in juvenile justice settings. We adapted a rapid screen for the identification of PD in adults (Standardised Assessment of Personality - Abbreviated Scale; SAPAS) for use with adolescents and then carried out a study of the reliability and validity of the adapted instrument in a sample of 80 adolescent boys in secure institutions. Participants were administered the screen and shortly after an established diagnostic interview for DSM-IV PDs. Nine days later the screen was readministered. A score of 3 or more on the screening interview correctly identified the presence of DSM-IV PD in 86% of participants, yielding a sensitivity and specificity of 0.87 and 0.86 respectively. Internal consistency was modest but comparable to the original instrument. 9-days test-retest reliability for the total score was excellent. Convergent validity correlations with the total number of PD criteria were large. This study provides preliminary evidence of the validity, reliability, and usefulness of the screen in secure institutions for adolescent male offenders. It can be used in juvenile offender institutions with limited resources, as a brief, acceptable, staff-administered routine screen to identify individuals in need of further assessment of PD or by researchers conducting epidemiological surveys.

Evidence-Based Practice Guideline: Depression Detection in Older Adults With Dementia.

PubMed

Brown, Ellen Leslie; Raue, Patrick J; Halpert, Karen

2015-11-01

Depression and dementia are the two most common psychiatric syndromes in the older adult population. Depression in older adults with and without dementia often goes unrecognized and untreated. The current guideline recommends a three-step procedure that can be used across health care settings to screen for the presence of depressive symptoms. Implementation of the evidence-based guideline requires administration of the Mini-Mental State Examination and either the Geriatric Depression Scale Short Form or Cornell Scale for Depression in Dementia, depending on level of cognitive functioning. The algorithm provided is designed to be used by nurses, physicians, and social workers for the purpose of depression screening in older adults with dementia. Detection of depression in individuals with dementia is hindered by a lack of a validated, brief screening tool. More research is needed on the use of such screenings among older adults with cognitive impairment. Copyright 2015, SLACK Incorporated.

To develop and examine the validity of a new brief cognitive test with less educational bias for screening cognitive impairment. A new cognitive test, Hong Kong Brief Cognitive Test (HKBC), was developed based on review of the literature, as well as the views of an expert panel. Three groups of subjects aged 65 or above were recruited after written consent: normal older people recruited in elderly centres, people with mild NCD (neurocognitive disorder), and people with major NCD. The brief cognitive test, Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA), were administered to the subjects. The performance of HKBC in differentiating subjects with major NCD, mild NCD, and normal older people were compared with the clinical diagnosis, as well as the MMSE and MoCA scores. In total, 359 subjects were recruited, with 99 normal controls, 132 subjects with major NCD, and 128 with mild NCD. The mean MMSE, MoCA, and HKBC scores showed significant differences among the 3 groups of subjects. In the receiving operating characteristic curve analysis of the HKBC in differentiating normal subjects from those with cognitive impairment (mild NCD + major NCD), the area under the curve was 0.955 with an optimal cut-off score of 21/22. The performances of MMSE and MoCA in differentiating normal from cognitively impaired subjects are slightly inferior to the HKBC. The HKBC is a brief instrument useful for screening cognitive impairment in older adults and is also useful in populations with low educational level. Copyright © 2018 John Wiley & Sons, Ltd.

2018-01-01

Background Antenatal depression and anxiety disorders are highly prevalent in low and middle-income countries. Screening of pregnant women in primary care antenatal settings provides an opportunity for entry to care, but data are needed on the performance of different screening tools. We compared five widely-used questionnaires in a sample of pregnant women in urban South Africa. Method Pregnant women attending a primary care antenatal clinic were administered five tools by trained research assistants: the Edinburgh Postnatal Depression Scale (EPDS), the Patient Health Questionnaire (PHQ-9), the Kessler Psychological Distress scale (K10) and a shortened 6-item version (K6), the Whooley questions and the two-item Generalised Anxiety Disorder scale (GAD-2). Following this, a registered mental health counsellor administered the MINI Plus, a structured clinical diagnostic interview. The Area Under the Curve (AUC) from Receiver Operator Characteristic curve analysis was used to summarise screening test performance and Cronbach’s α used to assess internal consistency. Results Of 376 participants, 32% were diagnosed with either MDE and/or anxiety disorders. All five questionnaires demonstrated moderate to high performance (AUC = 0.78–0.85). The EPDS was the best performing instrument for detecting MDE and the K10 and K6 for anxiety disorder. For MDE and/or anxiety disorders, the EPDS had the highest AUC (0.83). Of the short instruments, the K10 (AUC = 0.85) and the K6 (AUC = 0.85) performed the best, with the K6 showing good balance between sensitivity (74%) and specificity (85%) and a good positive predictive value (70%). The Whooley questions (AUC = 0.81) were the best performing ultra-short instrument. Internal consistency ranged from good to acceptable (α = 0.89–0.71). However, the PPV of the questionnaires compared with the diagnostic interview, ranged from 54% to 71% at the optimal cut-off scores. Conclusions Universal screening for case identification of antenatal depression and anxiety disorders in low-resource settings can be conducted with a number of commonly used screening instruments. Short and ultra-short screening instruments such as the K6 and the Whooley questions may be feasible and acceptable for use in these settings. PMID:29668725

Objectives. We compared substance use and SBIRT (Screening, Brief Intervention, and Referral to Treatment) services received for older adults screened by the Florida BRITE (BRief Intervention and Treatment of Elders) Project, across 4 categories of service providers. Methods. Staff from 29 agencies screened for substance use risk in 75 sites across 18 Florida counties. Clients at no or low risk received feedback about screening; moderate risk led to brief intervention, moderate or high risk led to brief treatment, and highest severity led to referral to treatment. Six-month follow-ups were conducted with a random sample of clients. Results. Over 5 years (September 15, 2006–September 14, 2011), 85 001 client screenings were recorded. Of these, 8165 clients were at moderate or high risk. Most received brief intervention for alcohol or medication misuse. Differences were observed across 4 categories of agencies. Health educators screening solely within medical sites recorded fewer positive screens than those from mental health, substance abuse, or aging services that screened in a variety of community-based and health care sites. Six-month follow-ups revealed a significant decrease in substance use. Conclusions. The Florida BRITE Project demonstrated that SBIRT can be extended to nonmedical services that serve older adults.

Estimate the effectiveness of brief interventions in reducing trauma recidivism in hospitalized trauma patients who screened positive for alcohol and/or illicit drug use. Dynamic cohort study based on registry data from 1818 patients included in a screening and brief intervention program for alcohol and illicit drug use for hospitalized trauma patients. Three subcohorts emerged from the data analysis: patients who screened negative, those who screened positive and were offered brief intervention, and those who screened positive and were not offered brief intervention. Follow-up lasted from 10 to 52 months. Trauma-free survival, adjusted hazard rate ratios (aHRR) and adjusted incidence rate ratios (aIRR) were calculated, and complier average causal effect (CACE) analysis was used. We found a higher cumulative risk of trauma recidivism in the subcohort who screened positive. In this subcohort, an aHRR of 0.63 (95% CI: 0.41-0.95) was obtained for the group offered brief intervention compared to the group not offered intervention. CACE analysis yielded an estimated 52% reduction in trauma recidivism associated with the brief intervention. The brief intervention offered during hospitalization in trauma patients positive for alcohol and/or illicit drug use can halve the incidence of trauma recidivism.

The International HIV Dementia Scale (IHDS) was developed to screen for HIV-associated dementia, but it has been used more generally for HIV-associated neurocognitive disorder (HAND). This study sought to examine the accuracy of the IHDS in a cohort of Brazilian HIV-infected individuals and compare its performance to an alternative screening battery for detecting HAND. A total of 108 participants (including 60 HIV-infected persons) completed the IHDS and a gold standard neuropsychological (NP) battery of 17 tests. As alternative screening method, all possible 3-test combinations from the NP battery were examined and a superiority index (a marker of specificity and sensitivity) was calculated. Sensitivity and specificity to HAND using the standard IHDS cutpoint of 10 were 36% and 75%, respectively. The best balance between sensitivity and specificity was accomplished with a modified cutpoint of 11.5, which yielded sensitivity of 72% and specificity of 58%. The top two most sensitive test combinations, compared with the gold standard NP battery, were Trail Making Test A, Wechsler Adult Intelligence Scale III Digit Symbol and Hopkins Verbal Learning Test-Revised Total Recall (sensitivity 91%, specificity 96%), and Digit Symbol, Brief Visuospatial Memory Test-Revised Total Recall and Grooved Pegboard Test-dominant hand (sensitivity 94%, specificity 91%). Both test combinations can be administered in less than 10 minutes and were more accurate than the IHDS in classifying HIV+ participants as NP impaired or unimpaired. These data suggest that demographically corrected T-scores from commonly used NP measures with modest time and material demands can improve identification of patients with HAND who may benefit from a more extensive NP examination.

An ultra scale-down primary recovery sequence was established for a platform E. coli Fab production process. It was used to evaluate the process robustness of various bioengineered strains. Centrifugal discharge in the initial dewatering stage was determined to be the major cause of cell breakage. The ability of cells to resist breakage was dependant on a combination of factors including host strain, vector, and fermentation strategy. Periplasmic extraction studies were conducted in shake flasks and it was demonstrated that key performance parameters such as Fab titre and nucleic acid concentrations were mimicked. The shake flask system also captured particle aggregation effects seen in a large scale stirred vessel, reproducing the fine particle size distribution that impacts the final centrifugal clarification stage. The use of scale-down primary recovery process sequences can be used to screen a larger number of engineered strains. This can lead to closer integration with and better feedback between strain development, fermentation development, and primary recovery studies. Biotechnol.

Despite the over-representation of people with gambling problems in mental health populations, there is limited information available to guide the selection of brief screening instruments within mental health services. The primary aim was to compare the classification accuracy of nine brief problem gambling screening instruments (two to five items) with a reference standard among patients accessing mental health services. The classification accuracy of nine brief screening instruments was compared with multiple cut-off scores on a reference standard. Eight mental health services in Victoria, Australia. A total of 837 patients were recruited consecutively between June 2015 and January 2016. The brief screening instruments were the Lie/Bet Questionnaire, Brief Problem Gambling Screen (BPGS) (two- to five-item versions), NODS-CLiP, NODS-CLiP2, Brief Biosocial Gambling Screen (BBGS) and NODS-PERC. The Problem Gambling Severity Index (PGSI) was the reference standard. The five-item BPGS was the only instrument displaying satisfactory classification accuracy in detecting any level of gambling problem (low-risk, moderate-risk or problem gambling) (sensitivity = 0.803, specificity = 0.982, diagnostic efficiency = 0.943). Several shorter instruments adequately detected both problem and moderate-risk, but not low-risk, gambling: two three-item instruments (NODS-CLiP, three-item BPGS) and two four-item instruments (NODS-PERC, four-item BPGS) (sensitivity = 0.854-0.966, specificity = 0.901-0.954, diagnostic efficiency = 0.908-0.941). The four-item instruments, however, did not provide any considerable advantage over the three-item instruments. Similarly, the very brief (two-item) instruments (Lie/Bet and two-item BPGS) adequately detected problem gambling (sensitivity = 0.811-0.868, specificity = 0.938-0.943, diagnostic efficiency = 0.933-0.934), but not moderate-risk or low-risk gambling. The optimal brief screening instrument for mental health services wanting to screen for any level of gambling problem is the five-item Brief Problem Gambling Screen (BPGS). Services wanting to employ a shorter instrument or to screen only for more severe gambling problems (moderate-risk/problem gambling) can employ the NODS-CLiP or the three-item BPGS. Services that are only able to accommodate a very brief instrument can employ the Lie/Bet Questionnaire or the two-item BPGS. © 2017 Society for the Study of Addiction.

Substance use during pregnancy is at least as common as many of the medical conditions screened for and managed during pregnancy. While harmful and costly, it is often ignored or managed poorly. Screening, brief intervention, and referral to treatment is an evidence-based approach to manage substance use. In September 2012, the US Centers for Disease Control and Prevention convened an Expert Meeting on Perinatal Illicit Drug Abuse to help address key issues around drug use in pregnancy in the United States. This article reflects the formal conclusions of the expert panel that discussed the use of screening, brief intervention, and referral to treatment during pregnancy. Screening for substance use during pregnancy should be universal. It allows stratification of women into zones of risk given their pattern of use. Low-risk women should receive brief advice, those classified as moderate risk should receive a brief intervention, whereas those who are high risk need referral to specialty care. A brief intervention is a patient-centered form of counseling using the principles of motivational interviewing. Screening, brief intervention, and referral to treatment has the potential to reduce the burden of substance use in pregnancy and should be integrated into prenatal care.

Background Vestibular and ocular motor impairments and symptoms have been documented in patients with sport-related concussions. However, there is no current brief clinical screen to assess and monitor these issues. Purpose To describe and provide initial data for the internal consistency and validity of a brief clinical screening tool for vestibular and ocular motor impairments and symptoms after sport-related concussions. Study Design Cross-sectional study; Level of evidence, 2. Methods Sixty-four patients, aged 13.9 ± 2.5 years and seen approximately 5.5 ± 4.0 days after a sport-related concussion, and 78 controls were administered the Vestibular/Ocular Motor Screening (VOMS) assessment, which included 5 domains: (1) smooth pursuit, (2) horizontal and vertical saccades, (3) near point of convergence (NPC) distance, (4) horizontal vestibular ocular reflex (VOR), and (5) visual motion sensitivity (VMS). Participants were also administered the Post-Concussion Symptom Scale (PCSS). Results Sixty-one percent of patients reported symptom provocation after at least 1 VOMS item. All VOMS items were positively correlated to the PCSS total symptom score. The VOR (odds ratio [OR], 3.89; P <.001) and VMS (OR, 3.37; P <.01) components of the VOMS were most predictive of being in the concussed group. An NPC distance ≥5 cm and any VOMS item symptom score ≥2 resulted in an increase in the probability of correctly identifying concussed patients of 38% and 50%, respectively. Receiver operating characteristic curves supported a model including the VOR, VMS, NPC distance, and ln(age) that resulted in a high predicted probability (area under the curve = 0.89) for identifying concussed patients. Conclusion The VOMS demonstrated internal consistency as well as sensitivity in identifying patients with concussions. The current findings provide preliminary support for the utility of the VOMS as a brief vestibular/ocular motor screen after sport-related concussions. The VOMS may augment current assessment tools and may serve as a single component of a comprehensive approach to the assessment of concussions. PMID:25106780

Background There have been many randomized controlled trials of screening and brief alcohol intervention in primary care. Most trials have reported positive effects of brief intervention, in terms of reduced alcohol consumption in excessive drinkers. Despite this considerable evidence-base, key questions remain unanswered including: the applicability of the evidence to routine practice; the most efficient strategy for screening patients; and the required intensity of brief intervention in primary care. This pragmatic factorial trial, with cluster randomization of practices, will evaluate the effectiveness and cost-effectiveness of different models of screening to identify hazardous and harmful drinkers in primary care and different intensities of brief intervention to reduce excessive drinking in primary care patients. Methods and design GPs and nurses from 24 practices across the North East (n = 12), London and South East (n = 12) of England will be recruited. Practices will be randomly allocated to one of three intervention conditions: a leaflet-only control group (n = 8); brief structured advice (n = 8); and brief lifestyle counselling (n = 8). To test the relative effectiveness of different screening methods all practices will also be randomised to either a universal or targeted screening approach and to use either a modified single item (M-SASQ) or FAST screening tool. Screening randomisation will incorporate stratification by geographical area and intervention condition. During the intervention stage of the trial, practices in each of the three arms will recruit at least 31 hazardous or harmful drinkers who will receive a short baseline assessment followed by brief intervention. Thus there will be a minimum of 744 patients recruited into the trial. Discussion The trial will evaluate the impact of screening and brief alcohol intervention in routine practice; thus its findings will be highly relevant to clinicians working in primary care in the UK. There will be an intention to treat analysis of study outcomes at 6 and 12 months after intervention. Analyses will include patient measures (screening result, weekly alcohol consumption, alcohol-related problems, public service use and quality of life) and implementation measures from practice staff (the acceptability and feasibility of different models of brief intervention.) We will also examine organisational factors associated with successful implementation. Trial registration Current Controlled Trials ISRCTN06145674. PMID:19664255

Although excessive and compulsive shopping has been increasingly placed within the behavioral addiction paradigm in recent years, items in existing screens arguably do not assess the core criteria and components of addiction. To date, assessment screens for shopping disorders have primarily been rooted within the impulse-control or obsessive-compulsive disorder paradigms. Furthermore, existing screens use the terms 'shopping,' 'buying,' and 'spending' interchangeably, and do not necessarily reflect contemporary shopping habits. Consequently, a new screening tool for assessing shopping addiction was developed. Initially, 28 items, four for each of seven addiction criteria (salience, mood modification, conflict, tolerance, withdrawal, relapse, and problems), were constructed. These items and validated scales (i.e., Compulsive Buying Measurement Scale, Mini-International Personality Item Pool, Hospital Anxiety and Depression Scale, Rosenberg Self-Esteem Scale) were then administered to 23,537 participants (M age = 35.8 years, SD age = 13.3). The highest loading item from each set of four pooled items reflecting the seven addiction criteria were retained in the final scale, The Bergen Shopping Addiction Scale (BSAS). The factor structure of the BSAS was good (RMSEA = 0.064, CFI = 0.983, TLI = 0.973) and coefficient alpha was 0.87. The scores on the BSAS converged with scores on the Compulsive Buying Measurement Scale (CBMS; 0.80), and were positively correlated with extroversion and neuroticism, and negatively with conscientiousness, agreeableness, and intellect/imagination. The scores of the BSAS were positively associated with anxiety, depression, and low self-esteem and inversely related to age. Females scored higher than males on the BSAS. The BSAS is the first scale to fully embed shopping addiction within an addiction paradigm. A recommended cutoff score for the new scale and future research directions are discussed.

Although excessive and compulsive shopping has been increasingly placed within the behavioral addiction paradigm in recent years, items in existing screens arguably do not assess the core criteria and components of addiction. To date, assessment screens for shopping disorders have primarily been rooted within the impulse-control or obsessive-compulsive disorder paradigms. Furthermore, existing screens use the terms ‘shopping,’ ‘buying,’ and ‘spending’ interchangeably, and do not necessarily reflect contemporary shopping habits. Consequently, a new screening tool for assessing shopping addiction was developed. Initially, 28 items, four for each of seven addiction criteria (salience, mood modification, conflict, tolerance, withdrawal, relapse, and problems), were constructed. These items and validated scales (i.e., Compulsive Buying Measurement Scale, Mini-International Personality Item Pool, Hospital Anxiety and Depression Scale, Rosenberg Self-Esteem Scale) were then administered to 23,537 participants (Mage = 35.8 years, SDage = 13.3). The highest loading item from each set of four pooled items reflecting the seven addiction criteria were retained in the final scale, The Bergen Shopping Addiction Scale (BSAS). The factor structure of the BSAS was good (RMSEA = 0.064, CFI = 0.983, TLI = 0.973) and coefficient alpha was 0.87. The scores on the BSAS converged with scores on the Compulsive Buying Measurement Scale (CBMS; 0.80), and were positively correlated with extroversion and neuroticism, and negatively with conscientiousness, agreeableness, and intellect/imagination. The scores of the BSAS were positively associated with anxiety, depression, and low self-esteem and inversely related to age. Females scored higher than males on the BSAS. The BSAS is the first scale to fully embed shopping addiction within an addiction paradigm. A recommended cutoff score for the new scale and future research directions are discussed. PMID:26441749

2015-01-01

Although there is evidence of a distinct profile of executive dysfunction in Williams syndrome (WS), a rare genetically based neurodevelopmental disorder, the utility of informant reports of everyday executive function (EF) impairments and their relation to intelligence is not yet clear. Here we aimed to evaluate the functional impact of executive dysfunction in adults with WS and to establish the validity of child and adult versions of the most commonly used rating scale for EF assessment, the Behaviour Rating Inventory of Executive Function (BRIEF). We were also interested in whether distinct components of everyday EF relate to intelligence in WS. Parent report child (BRIEF-C) and adult (BRIEF-A) ratings were collected on 20 adults with WS (aged 18.5 to 53 years), with a mean IQ of 60.95 (SD = 17.67). Neuropsychological measures of EF included: The Shape School Test (Espy, 2007); select subdomains of EF from the Woodcock-Johnson III Tests of Cognitive Abilities, Australian Adaptation (WJ III COG); and select subdomains from the Vineland Adaptive Behaviour Scales, Second Edition—Parent Survey (Vineland-II). Results showed that the BRIEF-A, but not the BRIEF-C, was the most highly correlated with neuropsychological measures of EF, suggesting that it was a valid measure of the profile of EF impairments in adults with WS. The profile of everyday EF dysfunction revealed relative impairments in monitoring, working memory, planning and organisation in WS. In addition, both neuropsychological and rating scale measures showed an association between the shifting component of EF and intelligence. These findings indicate that the BRIEF-A is a valid measure of the multidimensional nature of real-world impairments in EF, and highlight its utility as a less labor intensive and low-cost screening tool for measuring specific EF impairments that could become the focus of targeted intervention in adults with WS.

[Screening methods for mild cognitive impairment in primary care].

Diagnosis of mild cognitive impairment (MCI) is always clinical and screening methods only indicate that the patient has a higher risk of this condition. In MCI, there is a slight decline in some cognitive abilities that does not affect activities of daily living and therefore does not produce social or occupational disability. The definitive diagnosis of MCI requires a considerable time investment that is very rarely possible to provide in primary care (PC) consultations. Hence the need for PC physicians to employ rapid and simple screening methods (brief cognitive assessment -BCA-) that allow objective identification of patients likely to have MCI in a few minutes. This article reviews the BCA tools that can truly be applied in less than 10 minutes. The phototest is a brief screening tool that is easy to use and interpret by physicians and is well accepted by patients. Consequently, it is one of the most useful tests in PC for screening of both MCI and dementia. In addition to BCA, instrumental activities of daily living scales should also be applied to differentiate MCI from dementia. Copyright © 2017 Sociedad Española de Geriatría y Gerontología.

Brief interventions such as Screening, a single session of Brief Intervention, and Referral to Treatment (SBIRT) have shown mixed effectiveness in primary care. However, there are indications that multi-session brief interventions may demonstrate more consistently positive outcomes, and perhaps a more intensive approach would be of benefit in addressing substance use in primary care. This study compared the effectiveness of SBIRT with a single BI session (BI/RT) to a multi-session brief-treatment intervention (BI/RT+) in primary care. We also developed easy-to-use, evidence-based materials to assist clinicians in delivering these interventions. This study was conducted in three Federally Qualified Healthcare Centers (FQHCs). A total of 10,935 patients were screened, and 600 individuals were recruited. The sample was primarily Black/African American (82 %) with a mean age of 40. Patients who attended a healthcare appointment were screened for substance use via the AUDIT and DAST. Patients were eligible for the study if they scored 8 or higher on the AUDIT, were using only marijuana and scored 2 or higher on the DAST, or were using other illicit drugs and scored 1 or higher on the DAST. Participants were randomly assigned to receive one-session BI/RT, or two to six sessions of brief intervention that incorporated elements of motivational enhancement therapy and cognitive-behavioral therapy (BI/RT+). Both interventions were delivered by behavioral health consultants at the FQHCs. Participants completed follow-up assessments every 3 months for 1 year. Primary outcome variables included substance use treatment sessions attended and days of substance use. Secondary outcomes included measures of health, employment, legal, and psychiatric functioning and HIV risk behaviors. Additionally, we will conduct an economic evaluation examining cost-effectiveness and will analyze outcomes from a process evaluation examining patient and provider experiences. The ability of brief interventions to impact substance use has great potential, but research findings have been mixed. By conducting a large-scale randomized controlled trial in real-world health centers, this study will answer important questions about the effectiveness of expanded BIs for patients who screen positive for risky substance use in primary care.

Background There is a wealth of evidence regarding the detrimental impact of excessive alcohol consumption on the physical, psychological and social health of the population. There also exists a substantial evidence base for the efficacy of brief interventions aimed at reducing alcohol consumption across a range of healthcare settings. Primary research conducted in emergency departments has reinforced the current evidence regarding the potential effectiveness and cost-effectiveness. Within this body of evidence there is marked variation in the intensity of brief intervention delivered, from very minimal interventions to more intensive behavioural or lifestyle counselling approaches. Further the majority of primary research has been conducted in single centre and there is little evidence of the wider issues of generalisability and implementation of brief interventions across emergency departments. Methods/design The study design is a prospective pragmatic factorial cluster randomised controlled trial. Individual Emergency Departments (ED) (n = 9) are randomised with equal probability to a combination of screening tool (M-SASQ vs FAST vs SIPS-PAT) and an intervention (Minimal intervention vs Brief advice vs Brief lifestyle counselling). The primary hypothesis is that brief lifestyle counselling delivered by an Alcohol Health Worker (AHW) is more effective than Brief Advice or a minimal intervention delivered by ED staff. Secondary hypotheses address whether short screening instruments are more acceptable and as efficient as longer screening instruments and the cost-effectiveness of screening and brief interventions in ED. Individual participants will be followed up at 6 and 12 months after consent. The primary outcome measure is performance using a gold-standard screening test (AUDIT). Secondary outcomes include; quantity and frequency of alcohol consumed, alcohol-related problems, motivation to change, health related quality of life and service utilisation. Discussion This paper presents a protocol for a large multi-centre pragmatic factorial cluster randomised trial to evaluate the effectiveness and cost-effectiveness of screening and brief interventions for hazardous alcohol users attending emergency departments.

Despite evidence of alcohol disparities between sexual minority and heterosexual individuals in the general population, research has not examined whether there are disparities in receipt of alcohol screening and brief intervention - together considered one of the highest prevention priorities for US adults. This study examined differences in alcohol use and receipt of alcohol screening and brief intervention across sexual minority status. Behavioral Risk Factor Surveillance System 2014 data from eight US states were used to estimate patterns of alcohol use and receipt of alcohol screening and brief intervention among persons reporting sexual orientation and a checkup in the last two years (N=47,800). Analyses were conducted in 2016-2017. Gay men and bisexual women reported higher rates of alcohol use on some measures compared to heterosexual men and women, respectively. There were some differences in screening and brief intervention by sexual orientation. Lesbian women were more likely to report being asked about heavy episodic drinking than heterosexual women, and among those reporting unhealthy alcohol use, gay men were less likely, and bisexual men were more likely, to report receiving brief intervention compared to heterosexual men. Overall similarities between sexual minorities and heterosexuals in alcohol use and receipt of screening and brief intervention are encouraging. Nonetheless, research is needed to confirm findings and understand mechanisms underlying disparities in receipt of brief intervention between gay and heterosexual men. Published by Elsevier B.V.

SCREENING FOR PERSONALITY DISORDERS

Morse, Jennifer Q.; Pilkonis, Paul A.

2010-01-01

A brief but valid self-report measure to screen for personality disorders (PDs) would be a valuable tool in making decisions about further assessment and in planning optimal treatments. In psychiatric and nonpsychiatric samples, we compared the validity of three screening measures: the PD scales from the Inventory of Interpersonal Problems, a self-report version of the Iowa Personality Disorder Screen, and the self-directedness scale of the Temperament and Character Inventory. Despite their different theoretical origins, the screeners were highly correlated in a range from .71 to .77. As a result, the use of multiple screeners was not a significant improvement over any individual screener, and no single screener stood out as clearly superior to the others. Each performed modestly in predicting the presence of any PD diagnosis in both the psychiatric and nonpsychiatric groups. Performance was best when predicting a more severe PD diagnosis in the psychiatric sample. The results also highlight the potential value of multiple assessments when relying on self-reports.

Assessing Bodily Preoccupations is sufficient: clinically effective screening for hypochondriasis.

PubMed

Höfling, Volkmar; Weck, Florian

2013-12-01

Hypochondriasis is a persistent psychiatric disorder and is associated with increased utilisation of health care services. However, effective psychiatric consultation interventions and CBT treatments are available. In the present study, we provide evidence of clinically effective screening for hypochondriasis. We describe the clinically effective identification of patients with a high probability of suffering from hypochondriasis. This identification is achieved by means of two brief standardised screening instruments, namely the Bodily Preoccupation (BP) Scale with 3 items and the Whiteley-7 (WI-7) with 7 items. Both the BP scale and the WI-7 were examined in a sample of 228 participants (72 with hypochondriasis, 80 with anxiety disorders and 76 healthy controls) in a large psychotherapy outpatients' unit, applying the DSM-IV criteria. Cut-off values for the BP scale and the WI-7 were computed to identify patients with a high probability of suffering from hypochondriasis. Additionally, other self-report symptom severity scales were completed in order to examine discriminant and convergent validity. Data was collected from June 2010 to March 2013. The BP scale and the WI-7 discriminated significantly between patients with hypochondriasis and those with an anxiety disorder (d=2.42 and d=2.34). Cut-off values for these two screening scales could be provided, thus identifying patients with a high probability of suffering from hypochondriasis. In order to reduce costs, the BP scale or the WI-7 should be applied in medical or primary care settings, to screen for patients with a high probability of hypochondriasis and to transfer them to further assessment and effective treatment. © 2013.

To compare the diagnostic utility of two screen-film systems for panoramic radiography, one based on green and the other on ultraviolet light. Two hundred consecutive adult patients with teeth in all four quadrants requiring panoramic radiographs were randomly allocated to one of two groups. One group was imaged with OGA L (CEA AB, Strängnäs, Sweden) film using Lanex Regular (Eastman Kodak, Rochester, NY, USA) screens (the Lanex group). The other group was imaged using Ultra-Vision (Dupont UK Limited, Hertfordshire, UK) film and screens (the Ultra-vision group). Two different panoramic machines were used, a Planmeca (Planmeca OY, Helsinki, Finland) and Cranex (Soredex Orion Corporation, Helsinki, Finland). The radiographs were evaluated by two radiographers for overall quality and any faults recorded. Two dental radiologists evaluated the crestal and apical areas of every standing tooth on a 4-point scale. The likelihood of getting a high-quality image with the different films was modelled using logistic regression, adjusting for the radiologist and the area of the tooth being examined. Inter- and intra-examiner agreement was calculated using Kappa and weighted Kappa where appropriate. The radiographers recorded no significant differences in positioning errors between the two groups of film. However, the films produced on the Cranex were less likely to be recorded as excellent. The radiologists' interexaminer agreement for the lower molars and upper incisors was only moderate at best (kappa = 0.56). No significant differences were found between the likelihood of the two types of film providing a high-quality image. Crestal areas were more likely to be scored well than apical areas. There were no differences in ease of discerning apical and crestal areas between the two screen-film systems. There was only poor to moderate agreement between the two radiologists. Ultra-Vision can be recommended as an alternative to existing rare earth systems for panoramic radiography.

Evaluating training of screening, brief intervention, and referral to treatment (SBIRT) for substance use: Reliability of the MD3 SBIRT Coding Scale.

Screening, brief intervention, and referral to treatment (SBIRT) has become an empirically supported and widely implemented approach in primary and specialty care for addressing substance misuse. Accordingly, training of providers in SBIRT has increased exponentially in recent years. However, the quality and fidelity of training programs and subsequent interventions are largely unknown because of the lack of SBIRT-specific evaluation tools. The purpose of this study was to create a coding scale to assess quality and fidelity of SBIRT interactions addressing alcohol, tobacco, illicit drugs, and prescription medication misuse. The scale was developed to evaluate performance in an SBIRT residency training program. Scale development was based on training protocol and competencies with consultation from Motivational Interviewing coding experts. Trained medical residents practiced SBIRT with standardized patients during 10- to 15-min videotaped interactions. This study included 25 tapes from the Family Medicine program coded by 3 unique coder pairs with varying levels of coding experience. Interrater reliability was assessed for overall scale components and individual items via intraclass correlation coefficients. Coder pair-specific reliability was also assessed. Interrater reliability was excellent overall for the scale components (>.85) and nearly all items. Reliability was higher for more experienced coders, though still adequate for the trained coder pair. Descriptive data demonstrated a broad range of adherence and skills. Subscale correlations supported concurrent and discriminant validity. Data provide evidence that the MD3 SBIRT Coding Scale is a psychometrically reliable coding system for evaluating SBIRT interactions and can be used to evaluate implementation skills for fidelity, training, assessment, and research. Recommendations for refinement and further testing of the measure are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

An eight-item activity scale was recently developed and validated for use as a prognostic tool in clinical research in children and adolescents. It is unclear, however, if this brief questionnaire is predictive of quantitative metrics of physical activity and fitness. The purposes of this study were to prospectively administer the Hospital for Special Surgery Pediatric Functional Activity Brief Scale to a large cohort of healthy adolescents to determine (1) if the activity scale exhibits any floor or ceiling effects; (2) if scores on the activity scale are correlated with standardized physical fitness metrics; and if so, (3) to determine the discrimination ability of the activity scale to differentiate between adolescents with healthy or unhealthy levels of aerobic capacity and calculate an appropriate cutoff value for its use as a screening tool. One hundred eighty-two adolescents (mean, 15.3 years old) prospectively completed the activity scale and four standardized metrics of physical fitness: pushups, sit-ups, shuttle run exercise (Progressive Aerobic Cardiovascular Endurance Run), and calculated VO2-max. Age, sex, and body mass index were also recorded. Pearson correlations, regression analyses, and receiver operating characteristic analyses were used to evaluate activity scale performance. The activity scale did not exhibit any floor or ceiling effects. Pushups (ρ = 0.28), sit-ups (ρ = 0.23), performance on the Progressive Aerobic Cardiovascular Endurance Run (ρ = 0.44), and VO2-max (ρ = 0.43) were all positively correlated with the activity scale score (Pearson correlations, all p < 0.001). Receiver operating characteristic analysis revealed that those with an activity score of ≤ 14 were at higher risk of having low levels of aerobic capacity. In the current study, activity score was free of floor and ceiling effects and predictive of all four physical fitness metrics. An activity score of ≤ 14 was associated with at-risk aerobic capacity previously shown to be associated with an increased risk of metabolic syndrome. This study is the first to prospectively validate an activity questionnaire against quantitative physical fitness assessments and provides further evidence substantiating its use in outcomes research and screening for healthy levels of childhood activity and fitness.

Early interventions can improve treatment outcomes for individuals with major psychiatric disorders and with nonspecific symptoms but increasingly impaired cognitive perception, emotions, and behaviour. One way used to identify people susceptible to psychosis is through the schizotypal personality trait. Persons with schizotypal characteristics have been identified with the widely used Schizotypal Personality Questionnaire-Brief. However, no suitable instruments are available to screen individuals in the Taiwanese population for evidence of early psychotic symptoms. The purpose of this study was to test the sensitivity and specificity of the Chinese version of the Schizotypal Personality Questionnaire-Brief for identifying undergraduate students' susceptibility to psychosis. Two-stage, cross-sectional survey design. The self-administered scale was tested in a convenience sample of 618 undergraduate students at a medical university in Taiwan. Among these students, 54 completed the scale 2 weeks apart for test-retest reliability, and 80 were tested to identify their susceptibility to psychosis. In Stage I, participants with scores in the top 6.5% were classified as the high-score group (n=40). The control group (n=40) was randomly selected from the remaining participants with scores <15 and matched by gender. These 80 students were asked to participate in psychiatric interviews in Stage II. The instrument was tested for reliability using intraclass correlation coefficients and the Kuder-Richardson formula 20. The instrument was analysed for optimal sensitivity and specificity using odds-ratio analysis and receiver operating characteristic curves. The 22-item Chinese version of the Schizotypal Personality Questionnaire-Brief had a 2-week test-retest reliability of 0.82 and internal consistency of 0.76. The optimal cut-off score was 17, with odds ratios of 24.4 and an area under the receiver operating characteristic curves of 0.83. The instrument had a sensitivity of 80.0% and specificity of 85.9% in identifying undergraduate students' susceptibility to psychosis. The Chinese version Schizotypal Personality Questionnaire-Brief is a reliable instrument, but should not be used as a screening tool until its psychometric properties have been evaluated in more detail. Other screening tools need to be used in future studies with the CSPQ-B to improve the accuracy of identifying susceptibility to psychosis among young adults. Copyright © 2010.

To determine the relation between existing levels of alcohol screening and brief intervention rates in five European jurisdictions and role security and therapeutic commitment by the participating primary healthcare professionals. Health care professionals consisting of, 409 GPs, 282 nurses and 55 other staff including psychologists, social workers and nurse aids from 120 primary health care centres participated in a cross-sectional 4-week survey. The participants registered all screening and brief intervention activities as part of their normal routine. The participants also completed the Shortened Alcohol and Alcohol Problems Perception Questionnaire (SAAPPQ), which measure role security and therapeutic commitment. The only significant but small relationship was found between role security and screening rate in a multilevel logistic regression analysis adjusted for occupation of the provider, number of eligible patients and the random effects of jurisdictions and primary health care units (PHCU). No significant relationship was found between role security and brief intervention rate nor between therapeutic commitment and screening rate/brief intervention rate. The proportion of patients screened varied across jurisdictions between 2 and 10%. The findings show that the studied factors (role security and therapeutic commitment) are not of great importance for alcohol screening and BI rates. Given the fact that screening and brief intervention implementation rate has not changed much in the last decade in spite of increased policy emphasis, training initiatives and more research being published, this raises a question about what else is needed to enhance implementation. © The Author 2015.

To investigate the psychometric properties of the BMSLSS-College among 723 college students. Internal consistency estimates explored scale reliability, factor analysis explored construct validity, and known-groups validity was assessed using the National College Youth Risk Behavior Survey and Harvard School of Public Health College Alcohol Study. Criterion-related validity was explored through analyses with the CDC's health-related quality of life scale and a social isolation scale. Acceptable internal consistency reliability, construct, known-groups, and criterion-related validity were established. Findings offer preliminary support for the BMSLSS-C; it could be useful in large-scale research studies, applied screening contexts, and for program evaluation purposes toward achieving Healthy People 2010 objectives.

Virtual Colonoscopy Screening With Ultra Low-Dose CT and Less-Stressful Bowel Preparation: A Computer Simulation Study

Computed tomography colonography (CTC) or CT-based virtual colonoscopy (VC) is an emerging tool for detection of colonic polyps. Compared to the conventional fiber-optic colonoscopy, VC has demonstrated the potential to become a mass screening modality in terms of safety, cost, and patient compliance. However, current CTC delivers excessive X-ray radiation to the patient during data acquisition. The radiation is a major concern for screening application of CTC. In this work, we performed a simulation study to demonstrate a possible ultra low-dose CT technique for VC. The ultra low-dose abdominal CT images were simulated by adding noise to the sinograms of the patient CTC images acquired with normal dose scans at 100 mA s levels. The simulated noisy sinogram or projection data were first processed by a Karhunen-Loeve domain penalized weighted least-squares (KL-PWLS) restoration method and then reconstructed by a filtered backprojection algorithm for the ultra low-dose CT images. The patient-specific virtual colon lumen was constructed and navigated by a VC system after electronic colon cleansing of the orally-tagged residue stool and fluid. By the KL-PWLS noise reduction, the colon lumen can successfully be constructed and the colonic polyp can be detected in an ultra low-dose level below 50 mA s. Polyp detection can be found more easily by the KL-PWLS noise reduction compared to the results using the conventional noise filters, such as Hanning filter. These promising results indicate the feasibility of an ultra low-dose CTC pipeline for colon screening with less-stressful bowel preparation by fecal tagging with oral contrast.

Brief measures of anxiety related severity and impairment that can be used across anxiety disorders and with subsyndromal anxiety are lacking. The Overall Anxiety Severity and Impairment Scale (OASIS) have shown strong psychometric properties with college students and primary care patients. This study examines sensitivity, specificity, and efficiency of an abbreviated version of the OASIS that takes only 2–3 minutes to complete using a non-clinical (college student) sample. 48 participants completed the OASIS and SCID for anxiety disorders, 21 had a diagnosis of ≥1 anxiety disorder, and 4 additional participants had a subthreshold diagnosis. A cut-score of 8 best discriminated those with anxiety disorders from those without, successfully classifying 78% of the sample with 69% sensitivity and 74% specificity. Results from a larger sample (n=171) showed a single factor structure and excellent convergent and divergent validity. The availability of cut-scores for a non-clinical sample furthers the utility of this measure for settings where screening or brief assessment of anxiety is needed. PMID:20609450

Screening and brief interventions for hazardous and harmful alcohol use in probation services: a cluster randomised controlled trial protocol

PubMed Central

2009-01-01

Background A large number of randomised controlled trials in health settings have consistently reported positive effects of brief intervention in terms of reductions in alcohol use. However, although alcohol misuse is common amongst offenders, there is limited evidence of alcohol brief interventions in the criminal justice field. This factorial pragmatic cluster randomised controlled trial with Offender Managers (OMs) as the unit of randomisation will evaluate the effectiveness and cost-effectiveness of different models of screening to identify hazardous and harmful drinkers in probation and different intensities of brief intervention to reduce excessive drinking in probation clients. Methods and design Ninety-six OMs from 9 probation areas across 3 English regions (the North East Region (n = 4) and London and the South East Regions (n = 5)) will be recruited. OMs will be randomly allocated to one of three intervention conditions: a client information leaflet control condition (n = 32 OMs); 5-minute simple structured advice (n = 32 OMs) and 20-minute brief lifestyle counselling delivered by an Alcohol Health Worker (n = 32 OMs). Randomisation will be stratified by probation area. To test the relative effectiveness of different screening methods all OMs will be randomised to either the Modified Single Item Screening Questionnaire (M-SASQ) or the Fast Alcohol Screening Test (FAST). There will be a minimum of 480 clients recruited into the trial. There will be an intention to treat analysis of study outcomes at 6 and 12 months post intervention. Analysis will include client measures (screening result, weekly alcohol consumption, alcohol-related problems, re-offending, public service use and quality of life) and implementation measures from OMs (the extent of screening and brief intervention beyond the minimum recruitment threshold will provide data on acceptability and feasibility of different models of brief intervention). We will also examine the practitioner and organisational factors associated with successful implementation. Discussion The trial will evaluate the impact of screening and brief alcohol intervention in routine probation work and therefore its findings will be highly relevant to probation teams and thus the criminal justice system in the UK.

Randomisation will be stratified by probation area. To test the relative effectiveness of different screening methods all OMs will be randomised to either the Modified Single Item Screening Questionnaire (M-SASQ) or the Fast Alcohol Screening Test (FAST). There will be a minimum of 480 clients recruited into the trial. There will be an intention to treat analysis of study outcomes at 6 and 12 months post intervention. Analysis will include client measures (screening result, weekly alcohol consumption, alcohol-related problems, re-offending, public service use and quality of life) and implementation measures from OMs (the extent of screening and brief intervention beyond the minimum recruitment threshold will provide data on acceptability and feasibility of different models of brief intervention). We will also examine the practitioner and organisational factors associated with successful implementation. The trial will evaluate the impact of screening and brief alcohol intervention in routine probation work and therefore its findings will be highly relevant to probation teams and thus the criminal justice system in the UK.Ethical approval was given by Northern & Yorkshire REC.

Screening and brief intervention for harmful substance use in medical settings is being promoted heavily in the United States. To justify service provision fiscally, the field needs accurate estimates of the number and type of staff required to provide services, and thus the time taken to perform activities used to deliver services. This study analyzed the time spent in activities for the component services of the substance misuse Screening, Brief Intervention and Referral to Treatment (SBIRT) program implemented in emergency departments, in-patient units and ambulatory clinics. Observers timed activities according to 18 distinct codes among SBIRT practitioners. Twenty-six US sites within four grantees. Five hundred and one practitioner-patient interactions; 63 SBIRT practitioners. Timing of practitioner activities. Delivery of component services of SBIRT. The mean (standard error) time to deliver services was 1:19 (0:06) for a pre-screen (n = 210), 4:28 (0:24) for a screen (n = 97) and 6:51 (0:38) for a brief intervention (n = 66). Estimates of service duration varied by setting. Overall, practitioners spent 40% of their time supporting SBIRT delivery to patients and 13% of their time delivering services. In the United States, support activities (e.g. reviewing the patient's chart, locating the patient, writing case-notes) for substance abuse Screening, Brief Intervention and Referral to Treatment require more staff time than delivery of services. Support time for screens and brief interventions in the emergency department/trauma setting was high compared with the out-patient setting. © 2017 Society for the Study of Addiction.

In a 2007 report, the US Surgeon General called for health care professionals to renew efforts to reduce underage drinking. Focusing on the adolescent patient, this review provides health care professionals with recommendations for alcohol-related screening, brief intervention, and referral to treatment. MEDLINE and published reviews were used to identify relevant literature. Several brief screening methods have been shown to effectively identify underage drinkers likely to have alcohol use disorders. After diagnostic assessment when germane, the initial intervention typically focuses on education, motivation for change, and consideration of treatment options. Internet-accessible resources providing effective brief interventions are available, along with supplemental suggestions for parents. Recent changes in federal and commercial insurance reimbursement policies provide some fiscal support for these services, although rate increases and expanded applicability may be required to prompt the participation of many practitioners. Nevertheless, advances in clinical methods and progress on reimbursement policies have made screening and brief intervention for underage drinking more feasible in general health care practice.

To evaluate health practitioners' confidence and knowledge of alcohol screening, brief intervention and referral after training in a culturally adapted intervention on alcohol misuse and well-being issues for trauma patients. Mixed methods, involving semi-structured interviews at baseline and a post-workshop questionnaire. Targeted acute care within a remote area major tertiary referral hospital. Ten key informants and 69 questionnaire respondents from relevant community services and hospital-based health care professionals. Screening and brief intervention training workshops and resources for 59 hospital staff. Self-reported staff knowledge of alcohol screening, brief intervention and referral, and satisfaction with workshop content and format. After training, 44% of participants reported being motivated to implement alcohol screening and intervention. Satisfaction with training was high, and most participants reported that their knowledge of screening and brief intervention was improved. Targeted educational interventions can improve the knowledge and confidence of inpatient staff who manage patients at high risk of alcohol use disorder. Further research is needed to determine the duration of the effect and influence on practice behaviour. Ongoing integrated training, linked with systemic support and established quality improvement processes, is required to facilitate sustained change and widespread dissemination. © 2015 National Rural Health Alliance Inc.

This paper examines two factors related to successfully implementing a brief alcohol screening throughout all community-based mental health organizations. The first issue is related to an organization's internal structures, such as culture and climate that can impede evidenced-based practice implementation. There is literature suggesting that organizational culture and climate affect decisions about whether evidence-based practices are adopted and implemented within health care agencies. Following this literature review on organizational barriers, the history and successes of adopting an alcohol screening and brief intervention are reviewed. Studying, identifying, and understanding the organizational factors associated with the successful dissemination and implementation of best practices throughout community-based mental health organizations would contribute to increasing the likelihood that an alcohol screening and brief intervention are implemented throughout mental health organizations.

Older adults prefer to remain in their own homes for as long as possible. The purpose of this article is to describe the development and preliminary validation of Making and Executing Decisions for Safe and Independent Living (MED-SAIL), a brief screening tool for capacity to live safely and independently in the community. Prospective preliminary validation study. Outpatient geriatrics clinic located in a community-based hospital. Forty-nine community-dwelling older adults referred to the clinic for a comprehensive capacity assessment. We examined internal consistency, criterion-based validity, concurrent validity, and accuracy of classification for MED-SAIL. The items included in MED-SAIL demonstrated internal consistency (5 items; α = 0.85). MED-SAIL was significantly correlated with the Independent Living Scales (r = 0.573, p ≤0.001) and instrumental activities of daily living (r = 0.440, p ≤0.01). The Mann-Whitney U test revealed significant differences between the no capacity and partial/full capacity classifications on MED-SAIL (U(48) = 60.5, Z = -0.38, p <0.0001). The area under the curve was 0.864 (95% confidence interval: 0.84-0.99). This study demonstrated the validity of MED-SAIL as a brief screening tool to identify older adults with impaired capacity for remaining safe and independent in their current living environment. MED-SAIL is useful tool for health and social service providers in the community for the purpose of referral for definitive capacity evaluation. Published by Elsevier Inc.

We wanted to prospectively evaluate the use of a brief screening tool for ongoing intimate partner violence (IPV), the OVAT, and to validate this tool against the present Index of Spouse Abuse (ISA). The design was a prospective survey during randomized 4-hour shifts in an urban emergency department setting. The scale consists of four questions developed based on our previous work. The ISA was compared as the gold standard for detection of present (ongoing) IPV. Of 362 eligible patients presenting during 75 randomized 4-hour shifts, 306 (85%) completed the study. The prevalence of ongoing IPV using the OVAT was 31% (95% CI 26% to 36%). For the ISA, the prevalence was 20% (95% CI 16% to 25%). Compared with the ISA, the sensitivity of the OVAT in detecting ongoing IPV was 86%, specificity 83%, negative predictive value 96%, positive predictive value 56%, with an accuracy of 84%. In conclusion, four brief questions can detect ongoing IPV to aid in identifying the victim.

To devise a brief screening instrument to detect partner violence and to partially validate this screen against established instruments. Prospective survey. Two urban, hospital-based emergency departments. Of 491 women presenting during 48 randomly selected 4-hour time blocks, 322 (76% of eligible patients) participated. Respondents had a median age of 36 years; 19% were black, 45% white, and 30% Hispanic, while 6% were of other racial or ethnic groups; 54% were insured. We developed a partner violence screen (PVS), consisting of 3 questions about past physical violence and perceived personal safety. We administered the PVS and 2 standardized measures of partner violence, the Index of Spouse Abuse (ISA) and the Conflict Tactics Scale (CTS). Sensitivity, specificity, and predictive values of the PVS were compared with the ISA and the CTS as criterion standards. The prevalence rate of partner violence using the PVS was 29.5% (95% confidence interval [CI], 24.6%-34.8%). For the ISA and CTS, the prevalence rates were 24.3% (95% CI, 19.2%-30.1 %) and 27.4% (95% CI, 21.7%-33.6%), respectively. Compared with the ISA, the sensitivity of the PVS in detecting partner abuse was 64.5%; the specificity was 80.3%. When compared with the CTS, sensitivity of the PVS was 71.4%; the specificity was 84.4%. Positive predictive values ranged from 51.3% to 63.4%, and negative predictive values ranged from 87.6% to 88.7%. Overall, 13.7% of visits were the result of acute episodes of partner violence. Three brief directed questions can detect a large number of women who have a history of partner violence.

Albright, Glenn; Bryan, Craig; Adam, Cyrille; McMillan, Jeremiah; Shockley, Kristen

Primary health care professionals are in an excellent position to identify, screen, and conduct brief interventions for patients with mental health and substance use disorders. However, discomfort in initiating conversations about behavioral health, time concerns, lack of knowledge about screening tools, and treatment resources are barriers. This study examines the impact of an online simulation where users practice role-playing with emotionally responsive virtual patients to learn motivational interviewing strategies to better manage screening, brief interventions, and referral conversations. Baseline data were collected from 227 participants who were then randomly assigned into the treatment or wait-list control groups. Treatment group participants then completed the simulation, postsimulation survey, and 3-month follow-up survey. Results showed significant increases in knowledge/skill to identify and engage in collaborative decision making with patients. Results strongly suggest that role-play simulation experiences can be an effective means of teaching screening and brief intervention.

Objective Unhealthy alcohol use is particularly risky for patients living with HIV (PLWH). Brief interventions reduce drinking among patients with unhealthy alcohol use, but whether its receipt in routine outpatient settings is associated with reduced drinking among PLWH with unhealthy alcohol use is unknown. We assessed whether PLWH who screened positive for unhealthy alcohol use were more likely to resolve unhealthy drinking one year later if they had brief alcohol intervention (BI) documented in their electronic health record in a national sample of PLWH from the Veterans Health Administration. Methods Secondary VA clinical and administrative data from the electronic medical record (EMR) were used to identify all positive alcohol screens (AUDIT-C score ≥ 5) documented among PLWH (10/01/09-5/30/13) followed by another alcohol screen documented 9–15 months later. Unadjusted and adjusted Poisson regression models assessed the association between brief intervention (advice to reduce drinking or abstain documented in EMR) and resolution of unhealthy alcohol use (follow-up AUDIT-C <5 with ≥ 2 point reduction). Results Overall 2,101 PLWH with unhealthy drinking (10/01/09-5/30/13) had repeat alcohol screens 9–15 months later. Of those, 77% had brief intervention documented after their first screen, and 61% resolved unhealthy alcohol use at follow-up. Documented brief intervention was not associated with resolution [Adjusted incidence rate ratio 0.96, (95% CI 0.90–1.02)]. Conclusions Documented brief intervention was not associated with resolving unhealthy alcohol use at follow-up screening among VA PLWH with unhealthy alcohol use. Effective methods of resolving unhealthy alcohol use in this vulnerable population are needed. PMID:28554608

The aim of this study is to determine whether the use of a mobile ultra-clean laminar airflow screen reduces the air-borne particle counts in the setting of a simulated procedure of an intra-vitreal injection. A mobile ultra-clean unidirectional airflow (UDF) screen was tested in a simulated procedure for intra-vitreal injections in a treatment room without mechanical ventilation. One UDF was passed over the instrument tray and the surgical area. The concentration of particles was measured in the background, over the instrument table, and next to the ocular area. The degree of protection was calculated at the instrument table and at the surgical site. Use of the UDF mobile screen reduced the mean particle concentration (particles > 0.3 microns) on the instrument table by a factor of at least 100.000 (p < 0.05), and over the patient's eye by at least a factor of 436 (p < 0.05), which in clinical practice translates into significantly reduced air contamination. Mobile UDF screen reduces the mean particle concentration substantially. The mobile UDF screen may therefore allow for a safer procedural environment for ambulatory care procedures such as intra-vitreal injections in treatment rooms.

Large-scale science computations and experiments require unprecedented network capabilities in the form of large bandwidth and dynamically stable connections to support data transfers, interactive visualizations, and monitoring and steering operations. A number of component technologies dealing with the infrastructure, provisioning, transport and application mappings must be developed and/or optimized to achieve these capabilities. We present a brief account of the following technologies that contribute toward achieving these network capabilities: (a) DOE UltraScienceNet and NSF CHEETAH network testbeds that provide on-demand and scheduled dedicated network connections; (b) experimental results on transport protocols that achieve close to 100% utilization on dedicated 1Gbps wide-area channels; (c) a scheme for optimally mapping a visualization pipeline onto a network to minimize the end-to-end delays; and (d) interconnect configuration and protocols that provides multiple Gbps flows from Cray X1 to external hosts.

Population-based alcohol screening, followed by brief intervention for patients who screen positive for unhealthy alcohol use, is widely recommended for primary care settings and considered a top prevention priority, but is challenging to implement. However, new policy initiatives in the U.S., including the Affordable Care Act, may help launch widespread implementation. While the nationwide Veterans Health Administration (VA) has achieved high rates of documented alcohol screening and brief intervention, research has identified quality problems with both. We conducted a qualitative key informant study to describe local implementation of alcohol screening and brief intervention from the perspectives of frontline adopters in VA primary care in order to understand the process of implementation and factors underlying quality problems. A purposive snowball sampling method was used to identify and recruit key informants from 5 VA primary care clinics in the northwestern U.S. Key informants completed 20-30 minute semi-structured interviews, which were recorded, transcribed, and qualitatively analyzed using template analysis. Key informants (N=32) included: clinical staff (n=14), providers (n=14), and administrative informants (n=4) with varying participation in implementation of and responsibility for alcohol screening and brief intervention at the medical center. Ten inter-related themes (5 a priori and 5 emergent) were identified and grouped into 3 applicable domains of Greenhalgh's conceptual framework for dissemination of innovations, including values of adopters (theme 1), processes of implementation (themes 2 and 3), and post-implementation consequences in care processes (themes 4-10). While key informants believed alcohol use was relevant to health and important to address, the process of implementation (in which no training was provided and electronic clinical reminders "just showed up") did not address critical training and infrastructure needs. Key informants lacked understanding of the goals of screening and brief intervention, believed referral to specialty addictions treatment (as opposed to offering brief intervention) was the only option for following up on a positive screen, reported concern regarding limited availability of treatment resources, and lacked optimism regarding patients' interest in seeking help. Findings suggest that the local process of implementing alcohol screening and brief intervention may have inadequately addressed important adopter needs and thus may have ultimately undermined, instead of capitalized on, staff and providers' belief in the importance of addressing alcohol use as part of primary care. Additional implementation strategies, such as training or academic detailing, may address some unmet needs and help improve the quality of both screening and brief intervention. However, these strategies may be resource-intensive and insufficient for comprehensively addressing implementation barriers. Published by Elsevier Inc.

Patient-Reported Measures of Narcolepsy: The Need for Better Assessment.

2017-05-15

Narcolepsy, a chronic disorder of the central nervous system, is clinically characterized by a symptom pentad that includes excessive daytime sleepiness, cataplexy, sleep paralysis, hypnopompic/hypnagogic hallucinations, and disrupted nighttime sleep. Ideally, screening and diagnosis instruments that assist physicians in evaluating a patient for type 1 or type 2 narcolepsy would be brief, easy for patients to understand and physicians to score, and would identify or rule out the need for electrophysiological testing. A search of the literature was conducted to review patient-reported measures used for the assessment of narcolepsy, mainly in clinical trials, with the goal of summarizing existing scales and identifying areas that may require additional screening questions and clinical practice scales. Of the seven scales reviewed, the Epworth Sleepiness Scale continues to be an important outcome measure to screen adults for excessive daytime sleepiness, which may be associated with narcolepsy. Several narcolepsy-specific scales have demonstrated utility, such as the Ullanlinna Narcolepsy Scale, Swiss Narcolepsy Scale, and Narcolepsy Symptom Assessment Questionnaire, but further validation is required. Although the narcolepsy-specific scales currently in use may identify type 1 narcolepsy, there are no validated questionnaires to identify type 2 narcolepsy. Thus, there remains a need for short, easily understood, and well-validated instruments that can be readily used in clinical practice to distinguish narcolepsy subtypes, as well as other hypersomnias, and for assessing symptoms of these conditions during treatment. © 2017 American Academy of Sleep Medicine

Although Candida species are the fourth most common cause of nosocomial blood stream infections in the United States, early diagnostic tools for invasive candidemia are lacking. Due to an increasing rate of candidemia, a new screening system is needed to detect the Candida species in a timely manner. Here we describe a novel method of detection using a solid-state micro-scale pore similar to the operational principles of a Coulter counter. With a steady electrolyte current flowing through the pore, measurements are taken of changes in the current corresponding to the shape of individual yeasts as they translocate or travel through the pore. The direct ultra-fast low concentration electrical addressing of C. albicans has established criteria for distinguishing individual yeast based on their structural properties, which may reduce the currently used methods' complexity for both identification and quantification capabilities in mixed blood samples.

The brief version of the Borderline Symptom List (BSL-23) is a self-rated scale developed from the initial 95-item version of Borderline Symptom List (BSL-95). The current study aimed to evaluate the psychometric properties of the Chinese version of the BSL-23. A total of 570 undergraduate students and 323 clinical patients completed the BSL-23, the borderline subscale of the Personality Diagnostic Questionnaire (PDQ-4+), the Center for Epidemiologic Studies Depression Scale (CES-D), the Barratt Impulsiveness Scale, 11th version (BIS-11), the Childhood Trauma Questionnaire (CTQ) and the Attachment Style Questionnaire (ASQ). A Confirmatory Factor Analysis (CFA) was conducted to test the one-factor structure of the BSL-23. Cronbach's alpha, Omega coefficient, Split-Half coefficient, Mean Inter-Item Correlation (M IC ) and test-retest reliability were also measured. The correlations between the BSL-23 and other psychological variables were used to assess criterion-related validity and convergent validity. Participants who scored ≥ 5 on the borderline subscale of the PDQ-4+ were placed into the borderline personality disorder (BPD) screening-positive group, while the others were placed into the screening-negative group. Independent sample t -tests were performed to examine the differences in BSL-23 scores between the BPD screening-positive group and the BPD screening-negative group. The CFA results supported the one-factor structure of the BSL-23 in both samples. The internal consistency was high both in the undergraduate sample (Cronbach's α = 0.93, Omega = 0.95, Split-Half coefficient = 0.89, M IC = 0.38) and the clinical sample (Cronbach's α = 0.97, Omega = 0.97, Split-Half coefficient = 0.96, M IC = 0.56). The test-retest reliability within 2 weeks was 0.62. The BSL-23 displayed moderate to high correlations with the PDQ-4+-Borderline subscale, the CES-D, the BIS-11, the CTQ and the ASQ ( r = 0.35 - 0.70). In addition, the BSL-23 discriminated between the BPD screening-positive and the BPD screening-negative participants, and also between the patient sample and undergraduate sample. In conclusion, the Chinese version of the BSL-23 has satisfactory psychometric properties to assess BPD symptoms.

Background The KIPPPI (Brief Instrument Psychological and Pedagogical Problem Inventory) is a Dutch questionnaire that measures psychosocial and pedagogical problems in 2-year olds and consists of a KIPPPI Total score, Wellbeing scale, Competence scale, and Autonomy scale. This study examined the reliability, validity, screening accuracy and clinical application of the KIPPPI. Methods Parents of 5959 2-year-old children in the Rotterdam area, the Netherlands, were invited to participate in the study. Parents of 3164 children (53.1% of all invited parents) completed the questionnaire. The internal consistency was evaluated and in subsamples the test-retest reliability and concurrent validity with regard to the Child Behavioral Checklist (CBCL). Discriminative validity was evaluated by comparing scores of parents who worried about their child’s upbringing and parent’s that did not. Screening accuracy of the KIPPPI was evaluated against the CBCL by calculating the Receiver Operating Characteristic (ROC) curves. The clinical application was evaluated by the relation between KIPPPI scores and the clinical decision made by the child health professionals. Results Psychometric properties of the KIPPPI Total score, Wellbeing scale, Competence scale and Autonomy scale were respectively: Cronbach’s alphas: 0.88, 0.86, 0.83, 0.58. Test-retest correlations: 0.80, 0.76, 0.73, 0.60. Concurrent validity was as hypothesised. The KIPPPI was able to discriminate between parents that worried about their child and parents that did not. Screening accuracy was high (>0.90) for the KIPPPI Total score and for the Wellbeing scale. The KIPPPI scale scores and clinical decision of the child health professional were related (p<0.05), indicating a good clinical application. Conclusion The results in this large-scale study of a diverse general population sample support the reliability, validity and clinical application of the KIPPPI Total score, Wellbeing scale and Competence scale. Also, the screening accuracy of the KIPPPI Total score and Wellbeing scale were supported. The Autonomy scale needs further study. PMID:23185388

Aims The US Veterans Health Administration [Veterans Affairs (VA)] used performance measures and electronic clinical reminders to implement brief intervention for unhealthy alcohol use. We evaluated whether documented brief intervention was associated with subsequent changes in drinking during early implementation. Design Observational, retrospective cohort study using secondary clinical and administrative data. Setting Thirty VA facilities. Participants Outpatients who screened positive for unhealthy alcohol use [Alcohol Use Disorders Identification Test Consumption (AUDIT-C ≥ 5)] in the 6 months after the brief intervention performance measure (n = 22 214) and had follow-up screening 9–15 months later (n = 6210; 28%). Measurements Multi-level logistic regression estimated the adjusted prevalence of resolution of unhealthy alcohol use (follow-up AUDIT-C <5 with ≥2 point reduction) for patients with and without documented brief intervention (documented advice to reduce or abstain from drinking). Findings Among 6210 patients with follow-up alcohol screening, 1751 (28%) had brief intervention and 2922 (47%) resolved unhealthy alcohol use at follow-up. Patients with documented brief intervention were older and more likely to have other substance use disorders, mental health conditions, poor health and more severe unhealthy alcohol use than those without (P-values < 0.05). Adjusted prevalences of resolution were 47% [95% confidence interval (CI) = 42–52%] and 48% (95% CI = 42–54%) for patients with and without documented brief intervention, respectively (P = 0.50). Conclusions During early implementation of brief intervention in the US Veterans Health Administration, documented brief intervention was not associated with subsequent changes in drinking among outpatients with unhealthy alcohol use and repeat alcohol screening.

2015-07-30

The Panic Disorder Screener (PADIS) was developed as a new screener to identify panic disorder in the community and to assess severity of symptoms. The PADIS was developed to fill a gap in existing screening measures, as there are no brief panic screeners available that assess severity. The current study aimed to test the performance of the screener relative to the Patient Health Questionnaire-panic scale (PHQ-panic). The 4-item PADIS was administered to 12,336 young Australian adults, together with the PHQ-panic. A subsample of 1674 participants also completed a phone-based clinical interview to determine whether they met DSM-IV criteria for panic disorder. The PADIS (77% sensitivity, 84% specificity) had higher sensitivity for identifying panic disorder based on clinical criteria than the PHQ-panic (57% sensitivity, 91% specificity), although with reduced specificity. Administration of the PADIS required a mean of 1.9 items, compared to 4.7 items for the PHQ-panic. Each one-point increase in PADIS score was associated with 69% increased odds of meeting clinical criteria for panic disorder. The PADIS was found to be a valid, reliable and brief panic screener that is freely available for use in research and clinical settings. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Background and aims The aim of this study was to test the screening properties of several combinations of items from gambling scales, in order to harmonize screening of gambling problems in epidemiological surveys. The objective was to propose two brief screening tools (three items or less) for a use in interviews and self-administered questionnaires. Methods We tested the screening properties of combinations of items from several gambling scales, in a sample of 425 gamblers (301 non-problem gamblers and 124 disordered gamblers). Items tested included interview-based items (Pathological Gambling section of the DSM-IV, lifetime history of problem gambling, monthly expenses in gambling, and abstinence of 1 month or more) and self-report items (South Oaks Gambling Screen, Gambling Attitudes, and Beliefs Survey). The gold standard used was the diagnosis of a gambling disorder according to the DSM-5. Results Two versions of the Rapid Screener for Problem Gambling (RSPG) were developed: the RSPG-Interview (RSPG-I), being composed of two interview items (increasing bets and loss of control), and the RSPG-Self-Assessment (RSPG-SA), being composed of three self-report items (chasing, guiltiness, and perceived inability to stop). Discussion and conclusions We recommend using the RSPG-SA/I for screening problem gambling in epidemiological surveys, with the version adapted for each purpose (RSPG-I for interview-based surveys and RSPG-SA for self-administered surveys). This first triage of potential problem gamblers must be supplemented by further assessment, as it may overestimate the proportion of problem gamblers. However, a first triage has the great advantage of saving time and energy in large-scale screening for problem gambling. PMID:27348558

Due to the increasing prevalence of diabetes mellitus, demand for diabetic retinopathy (DR) screening platforms is steeply increasing. Early detection and treatment of DR are key public health interventions that can greatly reduce the likelihood of vision loss. Current DR screening programs typically employ retinal fundus photography, which relies on skilled readers for manual DR assessment. However, this is labor-intensive and suffers from inconsistency across sites. Hence, there has been a recent proliferation of automated retinal image analysis software that may potentially alleviate this burden cost-effectively. Furthermore, current screening programs based on 2-dimensional fundus photography do not effectively screen for diabetic macular edema (DME). Optical coherence tomography is becoming increasingly recognized as the reference standard for DME assessment and can potentially provide a cost-effective solution for improving DME detection in large-scale DR screening programs. Current screening techniques are also unable to image the peripheral retina and require pharmacological pupil dilation; ultra-widefield imaging and confocal scanning laser ophthalmoscopy, which address these drawbacks, possess great potential. In this review, we summarize the current DR screening methods using various retinal imaging techniques, and also outline future possibilities. Advances in retinal imaging techniques can potentially transform the management of patients with diabetes, providing savings in health care costs and resources. PMID:26830491

2015-01-01

The disability associated with late life depression makes it an important target for screening. Identifying clinically significant depression symptoms in older adults who have known risk factors provides an important opportunity for early evaluation and treatment. Screening that leads to evaluation and treatment is critical to both preventing depression, and reducing the associated disability, symptom burden, and costs of major depressive disorders (MDD). The guideline described here recommends the 9-item Patient Health Questionnaire (PHQ-9) for screening because it is based on diagnostic criteria for MDD and has the advantages of being brief, self-administered, easily scored and interpreted, and reliable and valid in diverse populations and care settings. Nurses and allied health professionals who provide care to older adults across the continuum of care are uniquely positioned to identify at risk older adults, use depression screening scales, make needed referrals for evaluation and treatment, and monitor outcomes across time.

2011-08-01

The Inventory of Interpersonal Problems-47 (IIP-47) is a brief and valid self-report measure for screening Personality Disorders (PDs). This study examined internal consistency, factor structure, criterion validity, temporal stability, and operating characteristics of the Italian version of the IIP-47 in two independent samples: PD subjects (n = 120) and nonclinical subjects (n = 475). Alpha coefficients ranged from .70 to .90. Multiple-Group Confirmatory Factor Analyses showed that the five-correlated-factor model reported in literature had the highest measurement invariance across the two groups. Criterion validity was supported by correlations among IIP-47 scale scores and scores on established measures of personality dimensions and pathology. Test-retest indices ranged from .71 to .95. PD subjects scored significantly higher than nonclinical subjects on all IIP-47 scales and cut-off scores for different levels of specificity and sensibility are reported. It is concluded that the psychometric properties of the original IIP-47 were preserved in its Italian version.

To examine the conditions under which Screening, Brief Intervention and Referral to Treatment (SBIRT) programs can be sustained by health insurance payments. A mathematical model was used to estimate the number of patients needed for revenues to exceed costs. Three medical settings in the United States were examined: in-patient, out-patient and emergency department. Components of SBIRT were delivered by combinations of health-care practitioners (generalists) and behavioral health specialists. Practitioners in seven SBIRT programs who received grants from the US Substance Abuse and Mental Health Services Administration (SAMHSA). Program costs and revenues were measured using data from grantees. Patient flows were measured from administrative data and adjusted with prevalence and screening estimates from the literature. SBIRT can be sustained through health insurance reimbursement in out-patient and emergency department settings in most staffing mixes. To sustain SBIRT in in-patient programs, a patient flow larger than the national average may be needed; if that flow is achieved, the range of screens required to maintain a surplus is narrow. Sensitivity analyses suggest that the results are very sensitive to changes in the proportion of insured patients. Screening, Brief Intervention and Referral to Treatment programs in the United States can be sustained by health insurance payments under a variety of staffing models. Screening, Brief Intervention and Referral to Treatment programs can be sustained only in an in-patient setting with above-average patient flow (more than 2500 screens). Screening, Brief Intervention and Referral to Treatment programs in out-patient and emergency department settings can be sustained with below-average patient flows (fewer than 125 000 out-patient visits and fewer than 27 000 emergency department visits). © 2017 Society for the Study of Addiction.

Objectives To develop a brief, reliable and valid instrument to screen psychosocial risk among those who are undergoing genetic testing for Adult-Onset Hereditary Disease (AOHD). Design A prospective two-phase cohort study. Setting 5 genetic testing centres for AOHD, such as cancer, Huntington's disease or haemochromatosis, in ambulatory clinics of tertiary hospitals across Canada. Participants 141 individuals undergoing genetic testing were approached and consented to the instrument development phase of the study (Phase I). The Genetic Psychosocial Risk Instrument (GPRI) developed in Phase I was tested in Phase II for item refinement and validation. A separate cohort of 722 individuals consented to the study, 712 completed the baseline package and 463 completed all follow-up assessments. Most participants were female, at the mid-life stage. Individuals in advanced stages of the illness or with cognitive impairment or a language barrier were excluded. Interventions Phase I: GPRI items were generated from (1) a review of the literature, (2) input from genetic counsellors and (3) phase I participants. Phase II: further item refinement and validation were conducted with a second cohort of participants who completed the GPRI at baseline and were followed for psychological distress 1-month postgenetic testing results. Primary and secondary outcome measures GPRI, Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), Brief Symptom Inventory (BSI) and Impact of Event Scale (IES). Results The final 20-item GPRI had a high reliability—Cronbach's α at 0.81. The construct validity was supported by high correlations between GPRI and BSI and IES. The predictive value was demonstrated by a receiver operating characteristic curve of 0.78 plotting GPRI against follow-up assessments using HAM-D and HAM-A. Conclusions With a cut-off score of 50, GPRI identified 84% of participants who displayed distress postgenetic testing results, supporting its potential usefulness in a clinical setting.

Despite the importance of identifying co-occurring psychiatric disorders in substance abuse treatment programs, there are few appropriate and validated instruments available to substance abuse treatment staff to conduct brief screen for these conditions. This paper describes the development, implementation and validation of a brief screening instrument for mental health diagnoses and trauma among a diverse sample of Black, Hispanic and White women in substance abuse treatment. With input from clinicians and consumers, we adapted longer existing validated instruments into a 14 question screen covering demographics, mental health symptoms and physical and sexual violence exposure. All women entering treatment (methadone, residential and out-patient) at five treatment sites were screened at intake (N = 374). Eighty nine percent reported a history of interpersonal violence, and 70% reported a history of sexual assault. Eighty-eight percent reported mental health symptoms in the last 30 days. The screening questions administered to 88 female clients were validated against in-depth psychiatric diagnostic assessments by trained mental health clinicians. We estimated measures of predictive validity, including sensitivity, specificity and predictive values positive and negative. Screening items were examined multiple ways to assess utility. The screen is a useful and valid proxy for PTSD but not for other mental illness. Substance abuse treatment programs should incorporate violence exposure questions into clinical use as a matter of policy. More work is needed to develop brief screening tools measures for front-line treatment staff to accurately assess other mental health needs of women entering substance abuse treatment.

Objectives Older adults prefer to remain in their own homes for as long as possible. The purpose of this article is to describe the development and preliminary validation of Making and Executing Decisions for Safe and Independent Living (MED-SAIL), a brief screening tool for capacity to live safely and independently in the community. Design Prospective preliminary validation study. Setting Outpatient geriatrics clinic located in a community-based hospital. Participants Forty-nine community-dwelling older adults referred to the clinic for a comprehensive capacity assessment. Measurements We examined internal consistency, criterion-based validity, concurrent validity, and accuracy of classification for MED-SAIL. Results The items included in MED-SAIL demonstrated internal consistency (5 items; α = 0.85). MED-SAIL was significantly correlated with the Independent Living Scales (r = 0.573, p ≤ 0.001) and instrumental activities of daily living (r = 0.440, p ≤ 0.01). The Mann-Whitney U test revealed significant differences between the no capacity and partial/full capacity classifications on MED-SAIL (U(48) = 60.5, Z = −0.38, p <0.0001). The area under the curve was 0.864 (95% confidence interval: 0.84–0.99). Conclusions This study demonstrated the validity of MED-SAIL as a brief screening tool to identify older adults with impaired capacity for remaining safe and independent in their current living environment. MED-SAIL is useful tool for health and social service providers in the community for the purpose of referral for definitive capacity evaluation. PMID:23567420

At-risk drinking and alcohol use disorders are common in primary care and may adversely affect the treatment of patients with diabetes and/or hypertension. The purpose of this article is to report the impact of dissemination of a practice-based quality improvement approach (Practice Partner Research Network-Translating Research into Practice [PPRNet-TRIP]) on alcohol screening, brief intervention for at-risk drinking and alcohol use disorders, and medications for alcohol use disorders in primary care practices. Nineteen primary care practices from 15 states representing 26,005 patients with diabetes and/or hypertension participated in a group-randomized trial (early intervention vs. delayed intervention). The 12-month intervention consisted of practice site visits for academic detailing and participatory planning and network meetings for "best practice" dissemination. At the end of Phase 1, eligible patients in early-intervention practices were significantly more likely than patients in delayed-intervention practices to have been screened (odds ratio [OR] = 3.30, 95% CI [1.15, 9.50]) and more likely to have been provided a brief intervention (OR = 6.58, 95% CI [1.69, 25.7]. At the end of Phase 2, patients in delayed-intervention practices were more likely than at the end of Phase 1 to have been screened (OR = 5.18, 95% CI [4.65, 5.76]) and provided a brief intervention (OR = 1.80, 95% CI [1.31, 2.47]). Early-intervention practices maintained their screening and brief intervention performance during Phase 2. Medication for alcohol use disorders was prescribed infrequently. PPRNet-TRIP is effective in improving and maintaining improvement in alcohol screening and brief intervention for patients with diabetes and/or hypertension in primary care settings.

Background Opportunities exist to disseminate evidence-based cancer control strategies to state-level policy makers in both the legislative and executive branches. We explored factors that influence the likelihood that state-level policy makers will find a policy brief understandable, credible, and useful. Methods A systematic approach was used to develop four types of policy briefs on the topic of mammography screening to reduce breast cancer mortality: data-focused brief with state-level data, data-focused brief with local-level data, story-focused brief with state-level data, and story-focused brief with local-level data. Participants were recruited from three groups of state-level policy makers—legislative staff, legislators, and executive branch administrators— in six states that were randomly chosen after stratifying all 50 states by population size and dominant political party in state legislature. Participants from each of the three policy groups were randomly assigned to receive one of the four types of policy briefs and completed a questionnaire that included a series of Likert scale items. Primary outcomes—whether the brief was understandable, credible, likely to be used, and likely to be shared—were measured by a 5-point Likert scale according to the degree of agreement (1 = strongly disagree, 5 = strongly agree). Data were analyzed with analysis of variance and with classification trees. All statistical tests were two-sided. Results Data on response to the policy briefs (n = 291) were collected from February through December 2009 (overall response rate = 35%). All three policy groups found the briefs to be understandable and credible, with mean ratings that ranged from 4.3 to 4.5. The likelihood of using the brief (the dependent variable) differed statistically significantly by study condition for staffers (P = .041) and for legislators (P = .018). Staffers found the story-focused brief containing state-level data most useful, whereas legislators found the data-focused brief containing state-level data most useful. Exploratory classification trees showed distinctive patterns for brief usefulness across the three policy groups. Conclusion Our results suggest that taking a “one-size-fits-all” approach when delivering information to policy makers may be less effective than communicating information based on the type of policy maker.

Objectives The objective of the present study was to explore whether the possibility of offering facilitated access to an alcohol electronic brief intervention (eBI) instead of delivering brief face-to-face advice increased the proportion of consulting adults who were screened and given brief advice. Design The study was a 12-week implementation study. Sixty primary healthcare units (PHCUs) in 5 jurisdictions (Catalonia, England, the Netherlands, Poland and Sweden) were asked to screen adults who attended the PHCU for risky drinking. Setting A total of 120 primary healthcare centres from 5 jurisdictions in Europe. Participants 746 individual providers (general practitioners, nurses or other professionals) participated in the study. Primary outcome Change in the proportion of patients screened and referred to eBI comparing a baseline 4-week preimplementation period with a 12-week implementation period. Results The possibility of referring patients to the eBI was not found to be associated with any increase in the proportion of patients screened. However, it was associated with an increase in the proportion of screen-positive patients receiving brief advice from 70% to 80% for the screen-positive sample as a whole (p<0.05), mainly driven by a significant increase in brief intervention rates in England from 87% to 96% (p<0.01). The study indicated that staff displayed a low level of engagement in this new technology. Staff continued to offer face-to-face advice to a larger proportion of patients (54%) than referral to eBI (38%). In addition, low engagement was seen among the referred patients; on average, 18% of the patients logged on to the website with a mean log-on rate across the different countries between 0.58% and 36.95%. Conclusions Referral to eBI takes nearly as much time as brief oral advice and might require more introduction and training before staff are comfortable with referring to eBI.

2016-01-01

Few studies examine the costs of conducting screening and brief intervention (SBI) in settings outside health care. This study addresses this gap in knowledge by examining the employer-incurred costs of SBI in an employee assistance program (EAP) when delivered by counselors. Screening was self-administered as part of the intake paperwork, and the brief intervention (BI) was delivered during a regular counseling session. Training costs were $76 per counselor. The cost of a screen to the employer was $0.64; most of this cost comprised the cost of the time the client spent completing the screen. The cost of a BI was $1.86. The cost of SBI is lower than cost estimates of SBI conducted in a health care setting. The low costs for the current study suggest that only modest gains in outcomes would likely be needed to justify delivering SBI in an EAP setting. PMID:21938602

Patient-Reported Measures of Narcolepsy: The Need for Better Assessment

Kallweit, Ulf; Schmidt, Markus; Bassetti, Claudio L.

2017-01-01

Study Objectives: Narcolepsy, a chronic disorder of the central nervous system, is clinically characterized by a symptom pentad that includes excessive daytime sleepiness, cataplexy, sleep paralysis, hypnopompic/hypnagogic hallucinations, and disrupted nighttime sleep. Ideally, screening and diagnosis instruments that assist physicians in evaluating a patient for type 1 or type 2 narcolepsy would be brief, easy for patients to understand and physicians to score, and would identify or rule out the need for electrophysiological testing. Methods: A search of the literature was conducted to review patient-reported measures used for the assessment of narcolepsy, mainly in clinical trials, with the goal of summarizing existing scales and identifying areas that may require additional screening questions and clinical practice scales. Results: Of the seven scales reviewed, the Epworth Sleepiness Scale continues to be an important outcome measure to screen adults for excessive daytime sleepiness, which may be associated with narcolepsy. Several narcolepsy-specific scales have demonstrated utility, such as the Ullanlinna Narcolepsy Scale, Swiss Narcolepsy Scale, and Narcolepsy Symptom Assessment Questionnaire, but further validation is required. Conclusions: Although the narcolepsy-specific scales currently in use may identify type 1 narcolepsy, there are no validated questionnaires to identify type 2 narcolepsy. Thus, there remains a need for short, easily understood, and well-validated instruments that can be readily used in clinical practice to distinguish narcolepsy subtypes, as well as other hypersomnias, and for assessing symptoms of these conditions during treatment.

Abstract Increases in mammalian cell culture titres and densities have placed significant demands on primary recovery operation performance. This article presents a methodology which aims to screen rapidly and evaluate primary recovery technologies for their scope for technically feasible and cost‐effective operation in the context of high cell density mammalian cell cultures. It was applied to assess the performance of current (centrifugation and depth filtration options) and alternative (tangential flow filtration (TFF)) primary recovery strategies. Cell culture test materials (CCTM) were generated to simulate the most demanding cell culture conditions selected as a screening challenge for the technologies. The performance of these technology options was assessed using lab scale and ultra scale‐down (USD) mimics requiring 25–110mL volumes for centrifugation and depth filtration and TFF screening experiments respectively. A centrifugation and depth filtration combination as well as both of the alternative technologies met the performance selection criteria. A detailed process economics evaluation was carried out at three scales of manufacturing (2,000L, 10,000L, 20,000L), where alternative primary recovery options were shown to potentially provide a more cost‐effective primary recovery process in the future. This assessment process and the study results can aid technology selection to identify the most effective option for a specific scenario. PMID:27067803

2018-01-01

The Psychopathic Personality Inventory-Revised (PPI-R) includes validity scales that assess Deviant Responding (DR), Virtuous Responding, and Inconsistent Responding. We examined the utility of these scales for identifying careless responding using data from two online studies that examined correlates of psychopathy in college students (Sample 1: N = 583; Sample 2: N = 454). Compared with those below the cut scores, those above the cut on the DR scale yielded consistently lower validity coefficients when PPI-R scores were correlated with corresponding scales from the Triarchic Psychopathy Measure. The other three PPI-R validity scales yielded weaker and less consistent results. Participants who completed the studies in an inordinately brief amount of time scored significantly higher on the DR and Virtuous Responding scales than other participants. Based on the findings from the current studies, researchers collecting PPI-R data online should consider identifying and perhaps screening out respondents with elevated scores on the DR scale.

Two mobile TOUL-400 units (types 1 and 2) that produce an exponential ultra-clean air flow (EUA) via a mobile screen were evaluated (maximum height from floor to centre of screen: type 1, 1.4m; type 2, 1.6m). Bacterial deposition rates were lowered by >60% (P=0.001) over a table area of 1.7 m (length)x1.0m (width) with the TOUL-400 type 1 unit, and the mean air count at 1.0m from the screen was reduced from 23 to 1.6 colony-forming units (CFU)/m3 in experiments in a room with six air changes/h (ACH). The corresponding reductions were two- to three-fold greater in an operating room (OR) with 16 ACH due to higher bacterial contamination levels in the control experiments. The dramatic but localized reduction of the deposition rate recorded on one 14-cm settle plate (>2376-fold at 0.8m from the screen in the OR) apparently reflected the focus of the EUA. The impact of the TOUL-400 unit was underestimated by almost 100-fold by the air counts of bacteria recorded in parallel at the same sampling point (26.5-fold reduction). During sham coronary angiography and sham hip arthroplasty performed in a room with six ACH, ultra-clean air (<10 CFU/m3) was obtained over the incision area with the TOUL-400 type 2 unit when the EUA was undisturbed (maximum screen-wound distance 1.7 m). In actual coronary angiography (room with six ACH, screen-wound distance 2.0-2.3m) and various surgical procedures in the OR (screen-wound distance 1.4-1.8m), ultra-clean air was obtained at the wound in three of 18 instances, characterized by undisturbed air flow and a maximum distance of 1.8 m. The newly developed TOUL-300 surgical instrument table (1.3-1.7 x 0.6m), equipped at one end with the same EUA unit as the TOUL-400 unit, was evaluated for a room with six ACH and an OR with 16 ACH. It yielded ultra-clean air at 0.8m (1.9 CFU/m3, 96% reduction, P=0.01) and reduced the deposition rate by >60% over most of the table surface. Simplified positioning of the screen or a longer reach, plus a mechanism for precise focusing of the air flow on to the wound area would increase the clinical utility of the TOUL EUA system.

To assess whether an additional chest ultra-low-dose CT scan to the coronary CT angiography protocol can be used for lung cancer screening among patients with suspected coronary artery disease. 175 patients underwent coronary CT angiography for assessment of coronary artery disease, additionally undergoing ultra-low-dose CT screening to early diagnosis of lung cancer in the same scanner (80kVp and 15mAs). Patients presenting pulmonary nodules were followed-up for two years, repeating low-dose CTs in intervals of 3, 6, or 12 months based on nodule size and growth rate in accordance with National Comprehensive Cancer Network guidelines. Ultra-low-dose CT identified 71 patients with solitary pulmonary nodules (41%), with a mean diameter of 5.50±4.00mm. Twenty-eight were >6mm, and in 79% (n=22) of these cases they were false positive findings, further confirmed by follow-up (n=20), resection (n=1), or biopsy (n=1). Lung cancer was detected in six patients due to CT screening (diagnostic yield: 3%). Among these, four cases could not be detected in the cardiac field of view. Most patients were in early stages of the disease. Two patients diagnosed at advanced stages died due to cancer complications. The addition of the ultra-low-dose CT scan represented a radiation dose increment of 1.22±0.53% (effective dose, 0.11±0.03mSv). Lung cancer might be detected using additional ultra-low-dose protocols in coronary CT angiography scans among patients with suspected coronary artery disease. Copyright © 2017 Elsevier B.V.

In 2007, of the 130 million emergency department (ED) visits, ∼ 38 million were due to injury, and of those, 1.9 million involved alcohol. The emergency department is a pivotal place to implement Screening, Brief Intervention, and Referral to Treatment (SBIRT) due to the high number of patients presenting with alcohol/substance abuse risk factors or related injuries. This study compares two surveys, approximately 11 years apart, of emergency physicians nationwide which assesses the use of validated screening tools, the availability of community resources for alcohol/substance abuse treatment, and the prevailing attitudes of emergency physicians regarding Screening and Brief Intervention for alcohol/substance abuse. We performed cross-sectional anonymous surveys of 1500 emergency physicians drawn from American College of Emergency Physicians members. The survey results were compared for time interval change. The two surveys had comparable response rates. The median percentage of patients screened for alcohol/substance abuse in 1999 was 15%, vs. 20% in 2010. In 2010, 26% of emergency physicians had a formal screening tool, and the majority used Cut-down, Annoyed, Guilty, Eye-opener (85%). In 2010, a statistically significant increase in the number of emergency physicians said they would "always" or "almost always" use discharge instructions that were specific for alcohol/substance abuse, if available, vs. 1999. Few emergency physicians screen for alcohol/substance abuse despite evidence that screening and brief intervention is effective. Emergency physicians are receptive to the use of discharge material.

Combining five commonly observed symptoms of late-life depression to develop a short depression screening tool with similar sensitivity and specificity as the conventional, more time-consuming tools. We developed the St. Louis University AM SAD (Appetite, Mood, Sleep, Activity, and thoughts of Death) questionnaire. The frequency of each symptom in the prior 2 weeks is quantified as 0, 1, or 2. Patients 65 years or older from our clinics were administered the AM SAD, the Geriatric Depression Scale (GDS-15), the Montgomery-Asberg Depression Rating Scale (MADRS), and the St. Louis University Mental Status Exam (SLUMS). 100 patients were selected. AM SAD correlation with GDS was 0.72 and MADRS 0.80. AM SAD yielded a sensitivity and specificity of 79% and 62% against diagnosis of depression; of 88% and 62% with GDS-15; and 92% and 71% with MADRS. The AM SAD can be reliably used as a short depression screening tool in patients with a SLUMS score of 20 or higher. Copyright © 2015 American Association for Geriatric Psychiatry.

There have been several attempts to identify individuals potentially at high risk for psychotic-spectrum disorders using brief screening measures. However, relatively few studies have tested the psychometric properties of the psychosis screening measures in representative samples of adolescents. The main purpose of the present study was to analyse the prevalence, factorial structure, measurement invariance across gender, and reliability of the Youth Psychosis At-Risk Questionnaire - Brief (YPARQ-B) in a community-derived sample of adolescents. Additionally, the relationship between YPARQ-B, depressive symptoms, psychopathology, stress manifestations, and prosocial skills was analysed. One thousand and twenty students from high schools participated in a cross-sectional survey. The YPARQ-B, the Reynolds Adolescent Depression Scale, the Strengths and Difficulties Questionnaire, and the Student Stress Inventory - Stress Manifestations were used. A total of 85.1% of the total sample self-reported at least one subclinical psychotic experience. We observed a total of 10.9% of adolescents with a cutoff score of ≥11 or 6.8% with a cutoff score of ≥13. The analysis of internal structure of the YPARQ-B yielded an essentially unidimensional structure. The YPARQ-B scores showed measurement invariance across gender. The internal consistency of the YPARQ-B total score was 0.94. Furthermore, self-reported subclinical psychotic experiences were associated with depressive symptoms, emotional and behavioural problems, poor prosocial skills, and stress manifestations. These results would appear to indicate that YPARQ-B is a brief and easy tool to assess self-reported subclinical psychotic experiences in adolescents from the general population. The assessment of these experiences in community settings, and its associations with psychopathology, may help us to enhance the possibility of an early identification of adolescents potentially at risk for psychosis and mental health problems.

Numerous studies have demonstrated that positive organizational climates contribute to better work performance. Screening and brief intervention (SBI) for alcohol, tobacco, and other drug use has the potential to reach a broad population of hazardous drug users but has not yet been widely adopted in Brazil's health care system. We surveyed 149 primary health care professionals in 30 clinics in Brazil who were trained to conduct SBI among their patients. We prospectively measured how often they delivered SBI to evaluate the association between organizational climate and adoption/performance of SBI. Organizational climate was measured by the 2009 Organizational Climate Scale for Health Organizations, a scale validated in Brazil that assesses leadership, professional development, team spirit, relationship with the community, safety, strategy, and remuneration. Performance of SBI was measured prospectively by weekly assessments during the three months following training. We also assessed self-reported SBI and self-efficacy for performing SBI at three months post-training. We used inferential statistics to depict and test for the significance of associations. Teams with better organizational climates implemented SBI more frequently. Organizational climate factors most closely associated with SBI implementation included professional development and relationship with the community. The dimensions of leadership and remuneration were also significantly associated with SBI. Organizational climate may influence implementation of SBI and ultimately may affect the ability of organizations to identify and address drug use.

Neurocognitive impairment (NCI) has been associated with poor clinical outcomes in various patient populations. This study used exploratory factor analysis (EFA) to examine the factor structure of the existing 95-item Neuropsychological Impairment Scale (NIS) to create a suitable NCI screening instrument for people living with HIV (PLH). In Lima, Peru, 313 HIV-positive men who have sex with men (MSM) and transgender women (TGW) prescribed antiretroviral therapy (ART) completed the NIS using computer-assisted self-interviews (CASI). The EFA used principal axis factoring and orthogonal varimax rotation, which resulted in 42 items with an 8-factor solution that explained 51.8% of the overall variance. The revised, 8-factor, Brief Inventory of Neurocognitive Impairment for Peru (BINI-P) showed a diverse set of factors with excellent to good reliability (i.e., F 1 α = 0.92 to F 8 α = 0.78). This EFA supports the use of the BINI-P to screen for NCI among Spanish-speaking, HIV-positive MSM and TGW. Future research should examine the effectiveness of the BINI-P in detecting NCI in clinical care settings and the impact of NCI on HIV health-related outcomes, including linkage and retention in care, ART adherence and HIV risk behaviors.

Recommended screening and brief intervention (SBI) for alcohol use during pregnancy is impeded by high patient loads and limited resources in public health settings. We evaluated the feasibility, acceptability and validity of a new self-administered, single-session, bilingual, computerized Screening and Brief Intervention (SBI) program for alcohol and sugar sweetened beverage (SSB) use in pregnancy. We developed and tested the computerized SBI program at a public health clinic with 290 pregnant women. Feasibility, acceptability, and validity measures were included in the program which had several modules, including those on demographics, health and beverage use. Time to complete the program and user experience items were used to determine program feasibility and acceptability. Validity analyses compared proportions of prenatal alcohol use identified by the program versus in-person screening by clinic staff. Most program users (87%, n = 251) completed the entire program; 91% (n = 263) completed the key screening and brief intervention modules. Most users also completed the program in ten to fifteen minutes. Program users reported that the program was easy to use (97%), they learned something new (88%), and that they would share what they learned with others (83%) and with their doctors or clinic staff (76%). Program acceptability did not differ by age, education, or type of beverage intervention received. The program identified alcohol use in pregnancy among 21% of users, a higher rate than the 13% (p < .01) found via screening by clinic staff. Computerized Screening and Brief Intervention for alcohol and SSB use in public health clinics is feasible and acceptable to English and Spanish speaking pregnant women and can efficiently identify prenatal alcohol use.

Cacace, Angela; Banks, Martyn; Spicer, Timothy; Civoli, Francesca; Watson, John

2003-09-01

G-protein-coupled receptors (GPCRs) are the most successful target proteins for drug discovery research to date. More than 150 orphan GPCRs of potential therapeutic interest have been identified for which no activating ligands or biological functions are known. One of the greatest challenges in the pharmaceutical industry is to link these orphan GPCRs with human diseases. Highly automated parallel approaches that integrate ultra-high throughput and focused screening can be used to identify small molecule modulators of orphan GPCRs. These small molecules can then be employed as pharmacological tools to explore the function of orphan receptors in models of human disease. In this review, we describe methods that utilize powerful ultra-high-throughput screening technologies to identify surrogate ligands of orphan GPCRs.

CPR training at mass gathering events is an important part of health initiatives to improve cardiac arrest survival. However, it is unclear whether training lay bystanders using an ultra-brief video at a mass gathering event improves CPR quality and responsiveness. To determine if showing a chest-compression only (CCO) Ultra-Brief Video (UBV) at a mass gathering event is effective in teaching lay bystanders CCO-CPR. Prospective control trial in adults (age >18) who attended either a women's University of Arizona or a men's Phoenix Suns basketball game. Participants were evaluated using a standardized cardiac arrest scenario with Laerdal Skillreporter™ mannequins. CPR responsiveness (calling 911, time to calling 911, starting compressions within two minutes) and quality (compression rate, depth, hands-off time) were assessed for participants and data collected at Baseline and Post-intervention. Different participants were tested before and after the exposure of the UBV. Data were analyzed via the intention to treat principle using logistic regression for binary outcomes and median regression for continuous outcomes, controlling for clustering by venue. A total of 96 people were consented (Baseline=45; Post intervention=51). CPR responsiveness post intervention improved with faster time to calling 911 (s) and time to starting compressions (sec). Likewise, CPR quality improved with deeper compressions and improved hands-off time. Showing a UBV at a mass gathering sporting event is associated with improved CPR responsiveness and performance for lay bystanders. This data provides further support for the use of mass media interventions. Copyright © 2017 Elsevier B.V. All rights reserved.

Friberg, B; Lindgren, M; Karlsson, C; Bergström, A; Friberg, S

2002-04-01

A mobile screen (0.5 x 0.4 m) producing ultra-clean exponential LAF (air-flow central zone 0.6 m/s and peripheral zone 0.4 m/s) was investigated as an addition to conventional turbulent/mixing operating room ventilation. The evaluation was performed during strictly standardized sham operations reflecting conditions during major surgery. The study consisted of a pilot experiment designed to give high counts of sedimenting aerobic colony forming units (cfu). In a second main study, recording dust particles, air-borne and sedimenting aerobic cfu, the screen was associated with optimal operating room clothing. In the pilot experiment the use of the screen resulted in a substantial reduction of sedimenting bacteria from 3835-4940 to 0-390 cfu/m(2)/h. In the main study, the use of the additional LAF reduced the surface contamination from 416-329 to 7-78 cfu/m(2)/h up to 1.6 m from the screen (P=0.001-0.0001). Measured in the wound area the screen reduced the air counts of bacteria from 9-14 to 0.2-0.4 cfu/m(3) (P=0.008-0.0001) and a marked reduction of air-borne dust particles was recorded (P=0.007-0.009). In conclusion, the additional mobile LAF screen reduced the counts of aerobic air-borne and sedimenting bacteria-carrying particles as well as dust particles to the levels gained with complete ultra-clean LAF room ventilation. Thus, the screen might prove a valuable addition to operating room ventilation as well as in other areas where asepsis is essential. Copyright 2002 The Hospital Infection Society.

2014-01-01

Background Brief intervention is known to reduce drinking in primary care, however because health care access is limited for Latino immigrants, traditional brief interventions are unlikely to reach this population. Methods Using Barrera and Castro’s framework, our study aims to culturally adapt a screening and brief intervention program to reduce unhealthy alcohol use among Latino day laborers, a particularly vulnerable group of Latino immigrant men. We conducted 18 interviews with Latino day laborers and 13 interviews with mental health and substance use providers that serve Latino immigrant men. Interviews were conducted until saturation of themes was reached. Themes from interviews were used to identify sources of mismatch between traditional screening and brief intervention and our target population. Results Unhealthy alcohol use was common, culturally accepted, and helped relieve immigration-related stressors. Men had limited knowledge about how to change their behavior. Men preferred to receive information from trusted providers in Spanish. Men faced significant barriers to accessing health and social services, but were open to receiving brief interventions in community settings. Findings were used to design Vida PURA, a preliminary adaptation design of brief intervention for Latino day laborers. Key adaptations include providing brief intervention at a day labor worker center, by promotores trained to incorporate the social and cultural context of drinking for Latino immigrant men. Conclusions Culturally adapted brief intervention may help reduce unhealthy drinking in this underserved population. PMID:25153904

The DSM‐5 Dimensional Anxiety Scales in a Dutch non‐clinical sample: psychometric properties including the adult separation anxiety disorder scale

2016-01-01

Abstract With DSM‐5, the American Psychiatric Association encourages complementing categorical diagnoses with dimensional severity ratings. We therefore examined the psychometric properties of the DSM‐5 Dimensional Anxiety Scales, a set of brief dimensional scales that are consistent in content and structure and assess DSM‐5‐based core features of anxiety disorders. Participants (285 males, 255 females) completed the DSM‐5 Dimensional Anxiety Scales for social anxiety disorder, generalized anxiety disorder, specific phobia, agoraphobia, and panic disorder that were included in previous studies on the scales, and also for separation anxiety disorder, which is included in the DSM‐5 chapter on anxiety disorders. Moreover, they completed the Screen for Child Anxiety Related Emotional Disorders Adult version (SCARED‐A). The DSM‐5 Dimensional Anxiety Scales demonstrated high internal consistency, and the scales correlated significantly and substantially with corresponding SCARED‐A subscales, supporting convergent validity. Separation anxiety appeared present among adults, supporting the DSM‐5 recognition of separation anxiety as an anxiety disorder across the life span. To conclude, the DSM‐5 Dimensional Anxiety Scales are a valuable tool to screen for specific adult anxiety disorders, including separation anxiety. Research in more diverse and clinical samples with anxiety disorders is needed. © 2016 The Authors International Journal of Methods in Psychiatric Research Published by John Wiley & Sons Ltd.

[The Battelle developmental inventory screening test for early detection of developmental disorders in cerebral palsy].

2011-12-01

Cerebral palsy is usually associated with motor, cognitive, and language deficits, and with other disorders that cause disability in daily living skills, personal independence, social interaction and academic activities. Early detection of these deficits in the clinical setting is essential to anticipate and provide the child with the necessary support for adapting to the environment in all possible areas. The main objective of this study is to demonstrate that these deficits can be detected at an early age and comprehensively through the use of a brief development scale. We studied 100 children between 4 and 70 months old, half of them with cerebral palsy and the other half without any disorder. All subjects were evaluated using the Battelle Developmental Inventory screening test. We compared the developmental quotients in both groups and between the subjects with different motor impairments, using a simple prospective ex post facto design. The test detected statistically significant differences between the clinical group and the control group at all age levels. Statistically significant differences were also found between tetraplegia and other motor disorders. There were no differences by gender. The deficit in development associated with cerebral palsy can be quantified at early ages through the use of a brief development scale, thus we propose that the systematic implementation of protocols with this screening tool would be helpful for treatment and early intervention. This would also help in anticipating and establishing the means for the multidisciplinary actions required, and could provide guidance to other health professionals, to provide adequate school, social, and family support,.

2017-01-01

Excessive or risky alcohol use is a preventable cause of significant morbidity and mortality in the U.S. and worldwide. Alcohol use is a common preventable cancer risk factor among young adults; it is associated with increased risk of developing at least six types of cancer. Alcohol consumed during early adulthood may pose a higher risk of female breast cancer than alcohol consumed later in life. Reducing alcohol use may help prevent cancer. Alcohol misuse screening and brief counseling or intervention (also called alcohol screening and brief intervention among other designations) is known to reduce excessive alcohol use, and the U.S. Preventive Services Task Force recommends that it be implemented for all adults aged ≥ 18 years in primary healthcare settings. Because the prevalence of excessive alcohol use, particularly binge drinking, peaks among young adults, this time of life may present a unique window of opportunity to talk about the cancer risk associated with alcohol use and how to reduce that risk by reducing excessive drinking or misuse. This article briefly describes alcohol screening and brief intervention, including the Centers for Disease Control and Prevention’s recommended approach, and suggests a role for it in the context of cancer prevention. The article also briefly discusses how the Centers for Disease Control and Prevention is working to make alcohol screening and brief intervention a routine element of health care in all primary care settings to identify and help young adults who drink too much.

The objective of the present study was to explore whether the possibility of offering facilitated access to an alcohol electronic brief intervention (eBI) instead of delivering brief face-to-face advice increased the proportion of consulting adults who were screened and given brief advice. The study was a 12-week implementation study. Sixty primary healthcare units (PHCUs) in 5 jurisdictions (Catalonia, England, the Netherlands, Poland and Sweden) were asked to screen adults who attended the PHCU for risky drinking. A total of 120 primary healthcare centres from 5 jurisdictions in Europe. 746 individual providers (general practitioners, nurses or other professionals) participated in the study. Change in the proportion of patients screened and referred to eBI comparing a baseline 4-week preimplementation period with a 12-week implementation period. The possibility of referring patients to the eBI was not found to be associated with any increase in the proportion of patients screened. However, it was associated with an increase in the proportion of screen-positive patients receiving brief advice from 70% to 80% for the screen-positive sample as a whole (p<0.05), mainly driven by a significant increase in brief intervention rates in England from 87% to 96% (p<0.01). The study indicated that staff displayed a low level of engagement in this new technology. Staff continued to offer face-to-face advice to a larger proportion of patients (54%) than referral to eBI (38%). In addition, low engagement was seen among the referred patients; on average, 18% of the patients logged on to the website with a mean log-on rate across the different countries between 0.58% and 36.95%. Referral to eBI takes nearly as much time as brief oral advice and might require more introduction and training before staff are comfortable with referring to eBI. NCT01501552; Post-results.

Family functioning plays an important role in developing and maintaining dysfunctional behaviors, especially during adolescence. The lack of indicators of family functioning, as determinants of personal and interpersonal problems, represents an obstacle to the activities aimed at developing preventive and intervention strategies. The Process Model of Family Functioning provides a conceptual framework organizing and integrating various concepts into a comprehensive family assessment; this model underlines that through the process of task accomplishment, each family meets objectives central to its life as a group. The Family Assessment Measure Third Edition (FAM III), based on the Process Model of Family Functioning, is among the most frequently used self-report instruments to measure family functioning. The present study aimed to evaluate the psychometric properties of the Italian version of the Family Assessment Measure Third Edition - Short Version (Brief FAM-III). It consists of three modules: General Scale, which evaluates the family as a system; Dyadic Relationships Scale, which examines how each family member perceives his/her relationship with another member; and Self-Rating Scale, which indicates how each family member is perceived within the nucleus. The developed Brief FAM-III together with the Family Assessment Device were administered to 484 subjects, members of 162 Italian families, formed of 162 fathers aged between 35 and 73 years; 162 mothers aged between 34 and 69 years; and 160 children aged between 12 and 35 years. Correlation, paired-sample t -test, and reliability analyses were carried out. General item analysis shows good indices of reliability with Cronbach's α coefficients equal to 0.96. The Brief FAM-III has satisfactory internal consistency, with Cronbach's α equal to 0.90 for General Scale, 0.94 for Dyadic Relationships Scale, and 0.88 for the Self-Rating Scale. The Brief FAM-III can be a psychometrically reliable and valid measure for the assessment of family strengths and weaknesses within Italian contexts. The instrument can be used to obtain an overall idea of family functioning, for the purposes of preliminary screening, and for monitoring family functioning over time or during treatment.

Background Family functioning plays an important role in developing and maintaining dysfunctional behaviors, especially during adolescence. The lack of indicators of family functioning, as determinants of personal and interpersonal problems, represents an obstacle to the activities aimed at developing preventive and intervention strategies. The Process Model of Family Functioning provides a conceptual framework organizing and integrating various concepts into a comprehensive family assessment; this model underlines that through the process of task accomplishment, each family meets objectives central to its life as a group.

Addiction to prescription opioids is prevalent in primary care settings. Increasing prescription opioid use is largely responsible for a parallel increase in overdose nationally. Many patients most at risk for addiction and overdose come into regular contact with primary care providers. Lack of routine addiction screening results in missed treatment opportunities in this setting. We reviewed the literature on screening and brief interventions for addictive disorders in primary care settings, focusing on opioid addiction. Screening and brief interventions can improve health outcomes for chronic illnesses including diabetes, hypertension, and asthma. Similarly, through the use of screening and brief interventions, patients with addiction can achieve improved health outcome. A spectrum of low-threshold care options can reduce the negative health consequences among individuals with opioid addiction. Screening in primary care coupled with short interventions, including motivational interviewing, syringe distribution, naloxone prescription for overdose prevention, and buprenorphine treatment are effective ways to manage addiction and its associated risks and improve health outcomes for individuals with opioid addiction.

Despite the negative consequences of alcohol and other drug use during pregnancy, few interventions for pregnant women are implemented, and little is known about their feasibility and acceptability in primary health care settings in South Africa. As part of the formative phase of screening, brief intervention, and referral to treatment for substance use among women presenting for antenatal care, the present study explored health care workers' attitudes and perceptions about screening, brief intervention, and referral to treatment among this population. Forty-three health care providers at 2 public sector midwife obstetric units in Cape Town, South Africa, were interviewed using an open-ended, semistructured interview schedule designed to identify factors that hinder or support the implementation of screening, brief intervention, and referral to treatment for substance use in these settings. Transcribed interviews were analyzed using the framework approach. Health care providers agreed that there is a substantial need for screening, brief intervention, and referral to treatment for substance use among pregnant women and believe such services potentially could be integrated into routine care. Several women-, staff-, and clinic-level barriers were identified that could hinder the successful implementation in antenatal services. These barriers included the nondisclosure of alcohol and other drug use, the intervention being considered as an add-on service or additional work, negative staff attitudes toward implementation of an intervention, poor staff communication styles such as berating women for their behavior, lack of interest from staff, time constraints, staff shortages, overburdened workloads, and language barriers. The utility of screening, brief intervention, and referral to treatment for addressing substance use among pregnant women in public health midwife obstetric units was supported, but consideration will need to be given to addressing a variety of barriers that have been identified. © 2015 by the American College of Nurse-Midwives.

Personality disorders (PDs) are considered to be potential predictors of treatment outcome in substance-dependent patients and potential treatment matching variables. There is a need for a brief and simple screening instrument for PDs that can be used in routine psychological assessment, especially in a treatment setting for previously substance-dependent criminal offenders, where a high prevalence of PDs is expected. This study investigated the psychometric properties of the Standardized Assessment of Personality-Abbreviated Scale (SAPAS), a commonly used screening interview for PDs, in a population of inpatient criminal offenders with a history of substance dependence. Various statistical procedures were used to establish reliability and validity measures, such as Kuder-Richardson 20, confirmative factor analysis, receiver operating characteristic analysis and multitrait multimethod matrix. The SAPAS was administered to 101 inpatient criminal offenders with a history of substance dependence at baseline. Within three weeks, participants were administered the Structured Interview for DSM-IV Personality in order to assess the presence of PDs. Results show limited evidence to make firm conclusions on the psychometric qualities of the SAPAS as a screening instrument for comorbid PDs in a substance dependence treatment setting for criminal offenders. Suggestions for improvement concerning the psychometric qualities of the SAPAS as a screening instrument for this population are noted. Copyright © 2012 John Wiley & Sons, Ltd.

Our objective was to assess the operating characteristics of the Psychological Development Questionnaire-1 (PDQ-1), an autism screener for use with young children. In Phase 1, we evaluated the concordance of the PDQ-1 with established autism scales, determined test-retest reliability, and identified a risk threshold score. In Phase 2, a population of 1959 toddler-age children was prospectively screened through multiple pediatric practices in a diverse metropolitan region, using the new instrument. Screen-positive children were referred for diagnostic evaluation. Screened children received follow-up at age 4 years to identify autism cases missed by screening and to specify the scale's psychometric properties. By screening a diverse population of low risk children, age 18 to 36 months, with the PDQ-1, we detected individuals with autism who had not come to professional attention. Overall, the PDQ-1 showed a positive predictive value (PPV) of 88%, with a sensitivity of 85% and specificity of 99% in a low risk population. High specificity, good sensitivity, and PPV were observed across the 18 to 36 month age-range. The findings provide preliminary empirical support for this parent report-based indicator of toddler psychological development and suggest that the PDQ-1 may be a useful supplement to developmental surveillance of autism. Additional research is needed with high risk samples and large, unselected populations under real-world conditions.

Symptoms of attention-deficit/hyperactivity disorder (ADHD) and psychosis risk share features which might represent an early vulnerability marker for schizophrenia. Early detection of individuals with this symptomatic overlap is relevant and may assist clinicians in their decision making for diagnosis and treatment. This study sought to analyze the capability of different instruments in the screening of patients for ADHD symptoms or at psychosis risk, assess their classification accuracy, and describe the extent of symptoms overlap between them. 243 adult patients completed one instrument screening for ADHD and two instruments screening for psychosis risk symptoms [Adult ADHD Self-Report Scale Symptom Checklist (ASRS-v1.1); Prodromal Questionnaire Brief Version (PQ-16); Self-Screen Prodrome (SPro)]. The ability of these instruments to distinguish between the symptomaticity of these patients appears modest. The most satisfactory scale to identify subjects at psychosis risk was SPro with its subscale psychosis risk. ASRS-v1.1 showed good reliability in assessing individuals as not having ADHD symptoms and had higher probability to achieve its own and the cut-off of another questionnaire. Subjects having symptoms of psychosis risk and ADHD showed elevated symptomatology. Reliable instruments capable of separating ADHD symptoms from those of psychosis risk are needed to better identify the symptomatic overlap of this two conditions. PMID:29163233

REVIEW ARTICLE: How will physics be involved in silicon microelectronics

NASA Astrophysics Data System (ADS)

1996-03-01

By the year 2000 electronics will probably be the basis of the largest industry in the world. Silicon microelectronics will continue to keep a dominant place covering 99% of the `semiconductor market'. The aim of this review article is to indicate for the next decade the domains in which research work in `physics' is needed for a technological advance towards increasing speed, complexity and density of silicon ultra large scale integration (ULSI) integrated circuits (ICs). By `physics' we mean here not only condensed matter physics but also the basic physical chemistry and thermodynamics. The review begins with a brief and general introduction in which we elucidate the current state of the art and the trends in silicon microelectronics. Afterwards we examine the involvement of physics in silicon microelectronics in the two main sections. The first section concerns the processes of fabrication of ICs: lithography, oxidation, diffusion, chemical and physical vapour deposition, rapid thermal processing, etching, interconnections, ultra-clean processing and microcontamination. The second section concerns the electrical operation of the ULSI devices. It defines the integration scales and points out the importance of the intermediate scale of integration which is the scale of the next generation of ICs. The emergence of cryomicroelectronics is also reviewed and an extended paragraph is dedicated to the problem of reliability and ageing of devices and ICs: hot carrier degradation, interdevice coupling and noise are considered. It is shown, during our analysis, that the next generation of silicon ICs needs mainly: (i) `scientific' fabrication and (ii) microscopic modelling and simulation of the electrical characteristics of the scaled down devices. To attain the above objectives a return to the `first principles' of physics as well as a recourse to nonlinear and non-equilibrium thermodynamics are mandatory. In the references we list numerous review papers and references of specialized colloquia proceedings so that a more detailed survey of the subject is possible for the reader.

Recently, screening of bioactive compounds by on-line ultra-high performance liquid chromatography (UHPLC) draws increasing attentions for the advantages of rapidity and intuition. Nevertheless, most on-line methods were limited to the shortcoming like low resolution and peak capacity, which could interfere the active ingredient identification. Comprehensive two-dimensional UHPLC (LC×LC) has revealed to be a powerful tool to separate complex mixtures. Herein, a strategy based on LC×LC analysis coupled with pre-column 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay was proposed to screen the antioxidants from the extract of Ginkgo biloba (EGB). A total of 61 compounds were identified in EGB, and 25 of them showed appreciable radical scavenging capacity. This work may offer pharmacodynamics base for further research about EGB, also the strategy is likelihood to be applied in screening antioxidant in other herbal medicine.

A personality trait that often elicits poor and uneasy interpersonal relationships is interpersonal sensitivity. The aim of the present study was to explore the relationship between interpersonal sensitivity and psychosocial functioning in individuals at ultra-high risk for psychosis as compared to help-seeking individuals who screened negative for an ultra-high risk of psychosis. A total sample of 147 adolescents and young adult who were help seeking for emerging mental health problems participated in the study. The sample was divided into two groups: 39 individuals who met criteria for an ultra-high-risk mental state (UHR), and 108 (NS). The whole sample completed the Interpersonal Sensitivity Measure (IPSM) and the Global Functioning: Social and Role Scale (GF:SS; GF:RS). Mediation analysis was used to explore whether attenuated negative symptoms mediated the relationship between interpersonal sensitivity and social functioning. Individuals with UHR state showed higher IPSM scores and lower GF:SS and GF:RS scores than NS participants. A statistically negative significant correlation between two IPSM subscales (Interpersonal Awareness and Timidity) and GF:SS was found in both groups. Our results also suggest that the relationship between the aforementioned aspects of interpersonal sensitivity and social functioning was not mediated by negative prodromal symptoms. This study suggests that some aspects of interpersonal sensitivity were associated with low level of social functioning. Assessing and treating interpersonal sensitivity may be a promising therapeutic target to improve social functioning in young help-seeking individuals.

Behavioral rating scales that assess impairments in executive function commonly associated with attention-deficit/hyperactivity disorder (ADHD) may offer advantages over neuropsychological testing. The primary objective of this study was to evaluate the efficacy of lisdexamfetamine dimesylate for executive function deficits in adults with ADHD and clinically significant executive function impairment using self-reported Behavior Rating Inventory of Executive Function-Adult version (BRIEF-A) assessments. This randomized double-blind study, conducted between May 2010 and November 2010, screened at least 1 participant at 35 of 39 registered US clinical research sites. Adults (aged 18-55 years) with a primary ADHD diagnosis (meeting full DSM-IV-TR criteria) and executive function deficits (assessed by baseline BRIEF-A Global Executive Composite [GEC] T-scores of at least 65) were randomized to treatment with optimized lisdexamfetamine dimesylate (30 mg/d, 50 mg/d, or 70 mg/d; n = 80) or placebo (n = 81) during a 10-week double-blind treatment period. Outcome measures included the BRIEF-A scales (GEC, index, and clinical subscales). At week 10 or at early termination, lisdexamfetamine dimesylate was associated with significantly greater reductions from baseline in mean BRIEF-A GEC T-scores than placebo (effect size, 0.74; P < .0001) and significantly greater reductions from baseline in mean T-scores for both BRIEF-A index scales (Behavioral Regulation Index and Metacognition Index) and all 9 clinical subscales (P ≤ .0056 for all). At week 10 or at early termination, mean T-scores for BRIEF-A indexes and clinical subscales were below levels of clinically significant executive function deficits (ie, < 65) with lisdexamfetamine dimesylate treatment. The mean (SD) GEC T-score was 57.2 (14.11) for the lisdexamfetamine dimesylate group and 68.3 (17.12) for the placebo group. The safety profile of lisdexamfetamine dimesylate was consistent with other long-acting psychostimulants. Among adults with ADHD and clinically significant executive function deficits, lisdexamfetamine dimesylate was associated with significant improvements in self-reported executive function ratings.

A mobile screen producing ultra-clean exponential laminar airflow (LAF) was investigated as an addition to conventional turbulent/mixing operating room (OR) ventilation (16 air changes/h). The evaluation was performed in a small OR (50 m(3)) during 60 standardized operations for groin hernia including mesh implantation. The additional ventilation was used in 50 of the operations. The LAF passed from the foot-end of the OR table over the instrument and surgical area. Strict hygiene OR procedures including tightly woven and non-woven OR clothing were used. Sedimentation rates were recorded at the level of the patients' chests (N=60) (i.e. the air had passed the surgical team) and in the periphery of the OR. In addition bacterial air contamination was studied above the patients' chests in all 10 operations without the additional LAF and in 12 with the LAF. The screen reduced the mean counts of sedimenting bacteria (cfu/m(2)/h) on the patients' chests from 775 without the screen to 355 (P=0.0003). The screen also reduced the mean air counts of bacteria (cfu/m(3)) above the patients' chests from 27 to 9 (P=0.0001). No significant differences in mean sedimentation rates (cfu/m(2)/h) existed in the periphery of the OR where 628 without and 574 with screen were recorded. During the follow-up period of six months no surgical site infections were detected. In conclusion when the mobile LAF screen was added to conventional OR ventilation the counts of aerobic airborne and sedimenting bacteria-carrying particles downstream of the surgical team were reduced to the levels achieved with complete ultra-clean LAF OR ventilation (operating box).

Deficits in social skills may present in a range of psychiatric disorders, particularly in the more serious and persistent conditions, and have an influence on functioning across various domains. This pilot study aimed at developing a brief measure, for structured evaluation and screening for social skills deficits, which can be easily integrated into routine clinical practice. The sample consisted of 380 inpatients and their accompanying caregivers, referred to Psychiatric Rehabilitation Services at a tertiary care government psychiatric hospital. The evaluation included an Inpatient intake Proforma and the 20-item Social Skills Assessment Screening Scale (SSASS). Disability was assessed using the Indian Disability Evaluation and Assessment Scale (IDEAS) for a subset of 94 inpatients. The analysis included means and standard deviations, frequency and percentages, Cronbach's alpha to assess internal consistency, t -tests to assess differences in social skills deficits between select subgroups, and correlation between SSASS and IDEAS scores. The results indicated the profile of social skills deficits assessed among the inpatients with varied psychiatric diagnoses. The "psychosis" group exhibited significantly higher deficits than the "mood disorder" group. Results indicated high internal consistency of the SSASS and adequate criterion validity demonstrated by correlations with select IDEAS domains. Modifications were made to the SSASS following the pilot study. The SSASS has potential value as a measure for screening and individualised intervention plans for social skills training in mental health and rehabilitation settings. The implications for future work on the psychometric properties and clinical applications are discussed.

2018-01-01

This paper discusses the rationale behind performing a brief geriatric assessment as a first step in the management of older patients in primary care practice. While geriatric conditions are considered by older patients and health professionals as particularly relevant for health and well-being, they remain too often overlooked due to many patient- and physician-related factors. These include time constraints and lack of specific training to undertake comprehensive geriatric assessment. This article discusses the epidemiologic rationale for screening functional, cognitive, affective, hearing and visual impairments, and nutritional status as well as fall risk and social status. It proposes using brief screening tests in primary care practice to identify patients who may need further comprehensive geriatric assessment or specific interventions.

Most nursing programs lack curriculum on substance use. This project evaluated 3 didactic instructional methods for teaching baccalaureate nursing students about screening, brief intervention, and referral to treatment for substance use. In-person, asynchronous narrated slides and interactive online instructional methods were all effective in developing students' competency; however, active learning methods (in-person and interactive online course) were more effective in changing students' attitudes about their role in screening and intervening for drug use.

The effectiveness of an evidence-based health care intervention depends on it being delivered consistently to appropriate patients. Brief alcohol intervention is known to be effective at reducing excessive drinking and its concomitant health and social problems. However, a recent implementation trial reported partial delivery of brief alcohol intervention by general practitioners (GPs) which is likely to have reduced its impact. To investigate patient-practitioner characteristics influencing brief alcohol intervention in primary care. Cross-sectional analysis of 12,814 completed Alcohol Use Disorders Identification Test (AUDIT) screening questionnaires. Eighty-four GPs who had implemented a brief alcohol intervention programme in a previous trial based in the Northeast of England. GPs were requested to screen all adults (aged over 16 years) presenting to their surgery and follow a structured protocol to give a brief intervention (five minutes of advice plus an information booklet) to all 'risk' drinkers. Anonymized carbon copies of the screening questionnaire were collected from all practices after a three-month implementation period. Although AUDIT identified 4080 'risk' drinkers, only 2043 (50%) received brief intervention. Risk drinkers that were most likely to receive brief intervention were males (58%), unemployed (61%), and technically-trained patients (55%). Risk drinkers that were least likely to receive brief intervention were females (44%), students (38%), and university educated patients (46%). Logistic regression modelling showed that patients' risk status was the most influential predictor of brief intervention. Also, GPs' experience of relevant training and longer average practice consultations predicted brief intervention. However, personal characteristics relating to patients and GPs also predicted brief intervention in routine practice. Interpersonal factors relating to patients and practitioners contributed to the selective provision of brief alcohol intervention in primary care. Ways should be found to remedy this situation or the impact of this evidence-based intervention may be reduced when implemented in routine practice.

We assessed the executive function in adults with attention-deficit/hyperactivity disorder (ADHD) during atomoxetine treatment in a randomized withdrawal trial. Responders (Conners' ADHD Rating Scale-Investigator Rated: Screening Version [adult prompts] ≥30% reduction from baseline and Clinical Global Impression Scale-ADHD Severity score ≤3) to open-label atomoxetine (40-100 mg/d, 12 weeks) entered a 37-week double-blind maintenance period. Patients who maintained response (double-blind atomoxetine for 12 weeks) were randomized 1:1 to atomoxetine (80-100 mg/d, n = 266) or placebo (n = 258) for 25 weeks (total duration, 1 year). Patients and investigators were blinded to response criteria and randomization timing. Change in executive function was assessed with the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) Self-Report and Informant T scores from the randomization to the last-observation-carried-forward postrandomization week 25 (after week 17). Of the enrolled patients (n = 2017; mean age, 33.2 years; male, 58.7%), 524 responders were randomized. During open-label atomoxetine, subscales and individual items on both BRIEF-A questionnaires showed significant improvement (P < 0.001). After randomization, the following T scores improved significantly (P ≤ 0.05) with patients in the atomoxetine group versus those in the placebo group: global executive composite, behavioral regulation, and metacognition indices; plan/organize, working memory, inhibit, task monitor and shift (both BRIEF-A questionnaires), emotional control and organization of materials (BRIEF-A Informant), and initiate (BRIEF-A Self-Report). Atomoxetine significantly improved the executive function compared with placebo, which was maintained for 25 weeks or more; the executive function of patients in the placebo group worsened but did not return to baseline levels after randomization.

Knowledge on associations between ultra-high risk (UHR) for developing psychosis and on non-psychotic psychopathology in help-seeking populations is limited with respect to differences between male and female patients. The present study tests the hypothesis that both social anxiety and depression are highly prevalent in an UHR population, particularly among women. From February 2008 to February 2010 baseline data were collected from help-seeking subjects (14-35 years) who were included in the Dutch Early Detection and Intervention Evaluation (EDIE-NL) trial. Two recruiting strategies were used: a two-stage screening strategy in a population of consecutive help-seeking and distressed subjects of secondary mental health services, and a referral strategy. This study included 201 patients with a mean age of 22.7 years. Of these, 102 (51%) were female, 58% of the patients met the criteria for clinical depression on the Beck Depression Inventory and 42% met the criteria for clinical social phobia on the Social Interaction Anxiety Scale. Women showed more depression and social anxiety than men. The results support the hypothesis that UHR is associated with depression and social anxiety, particularly in women. Screening a help-seeking population with depression and anxiety may be effective in detecting patients at UHR for developing psychosis. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To assess concordance between physician assessment and patient-reported symptoms when screening for depression in Parkinson disease (dPD). Depression in Parkinson disease is highly prevalent (∼40%) and has a significant impact on quality of life and disability, yet physician recognition and treatment remain inadequate. One thousand seventy-six patients with PD completed the Brief Symptom Inventory-18 (BSI-18), a screening questionnaire for psychiatric symptoms, which was compared to item #3 (depression) on the Unified Parkinson's Disease Rating Scale (UPDRS). The mean BSI-18 depression score was 51.4 (9.7). Of the 170 (16%) patients screening positive for dPD on the BSI-18, 104 (61%) were not recognized as depressed by neurologists on the UPDRS. Factors associated with lower neurologist recognition included male gender, better mental health quality of life, and lack of antidepressant use. More than 60% of patients screening positive for depression on self-report were not recognized by neurologists on the UPDRS. A patient-reported screening tool for depression may improve recognition and management of dPD.

OBJECTIVE: To evaluate the accuracy of the Edinburgh Postnatal Depression Scale (EPDS) and 3 subscales for identifying postpartum depression among primiparous adolescent mothers. METHODS: Mothers enrolled in a randomized controlled trial to prevent postpartum depression completed a psychiatric diagnostic interview and the 10-item EPDS at 6 weeks, 3 months, and 6 months postpartum. Three subscales of the EPDS were assessed as brief screening tools: 3-item anxiety subscale (EPDS-3), 7-item depressive symptoms subscale (EPDS-7), and 2-item subscale (EPDS-2) that resemble the Patient Health Questionnaire-2. Receiver operating characteristic curves and the areas under the curves for each tool were compared to assess accuracy. The sensitivities and specificities of each screening tool were calculated in comparison with diagnostic criteria for a major depressive disorder. Repeated-measures longitudinal analytical techniques were used. RESULTS: A total of 106 women contributed 289 postpartum visits; 18% of the women met criteria for incident postpartum depression by psychiatric diagnostic interview. When used as continuous measures, the full EPDS, EPDS-7, and EPDS-2 performed equally well (area under the curve >0.9). Optimal cutoff scores for a positive depression screen for the EPDS and EPDS-7 were lower (≥9 and ≥7, respectively) than currently recommended cutoff scores (≥10). At optimal cutoff scores, the EPDS and EPDS-7 both had sensitivities of 90% and specificities of >85%. CONCLUSIONS: The EPDS, EPDS-7, and EPDS-2 are highly accurate at identifying postpartum depression among adolescent mothers. In primary care pediatric settings, the EPDS and its shorter subscales have potential for use as effective depression screening tools. PMID:24344102

Although electroconvulsive therapy (ECT) is the most effective acute antidepressant intervention, sustained response rates are low. It has never been systematically assessed whether psychotherapy, continuation ECT, or antidepressant medication is the most efficacious intervention to maintain initial treatment response. In a prospective, randomized clinical trial, 90 inpatients with major depressive disorder (MDD) were treated with right unilateral ultra-brief acute ECT. Electroconvulsive therapy responders received 6 months guideline-based antidepressant medication (MED) and were randomly assigned to add-on therapy with cognitive-behavioral group therapy (CBT-arm), add-on therapy with ultra-brief pulse continuation electroconvulsive therapy (ECT-arm), or no add-on therapy (MED-arm). After the 6 months of continuation treatment, patients were followed-up for another 6 months. The primary outcome parameter was the proportion of patients who remained well after 12 months. Of 90 MDD patients starting the acute phase, 70% responded and 47% remitted to acute ECT. After 6 months of continuation treatment, significant differences were observed in the three treatment arms with sustained response rates of 77% in the CBT-arm, 40% in the ECT-arm, and 44% in the MED-arm. After 12 months, these differences remained stable with sustained response rates of 65% in the CBT-arm, 28% in the ECT-arm, and 33% in the MED-arm. These results suggest that ultra-brief pulse ECT as a continuation treatment correlates with low sustained response rates. However, the main finding implicates cognitive-behavioral group therapy in combination with antidepressants might be an effective continuation treatment to sustain response after successful ECT in MDD patients.

Cano, Annmarie; Sprafkin, Robert P.; Scaturo, Douglas J.; Lantinga, Larry J.; Fiese, Barbara H.; Brand, Frank

2001-01-01

Background: The current study compared 3 brief mental health screening measures in a sample of older patients in a primary care outpatient setting. Previous mental health screening research has been conducted primarily with younger patients, often with only 1 screening measure, thereby limiting the generalizability of findings. In addition, measures have not yet been compared in terms of their ability to discriminate between cases and noncases of psychiatric disorder. Method: One hundred thirty-four male patients attending their appointments at a primary care clinic in a Department of Veterans Affairs Medical Center participated in this study. Participants completed the General Health Questionnaire-12 (GHQ-12), the Symptom Checklist-10 (SCL-10), and the Primary Care Evaluation of Mental Disorders screening questionnaire and interview. Results: Receiver operating characteristic analysis yielded the optimum cutoff scores on each brief mental health screening measure and showed that all 3 measures discriminated well between cases and noncases of psychiatric disorders. The 3 measures performed slightly better in terms of discriminating between cases and noncases of mood or anxiety disorders than between cases and noncases of any psychiatric disorder. There were no significant differences between the measures' abilities to accurately identify cases and noncases of disorder. Conclusion: Primary care physicians are encouraged to use brief mental health screening measures with their patients, since many report symptoms of psychological distress and disorder. It is recommended that the SCL-10 and GHQ-12 be used to detect mood or anxiety disorders in patients such as these because of the accuracy and brevity of these measures. PMID:15014574

OBJECTIVE: Primary care providers need effective strategies for substance use screening and brief counseling of adolescents. We examined the effects of a new computer-facilitated screening and provider brief advice (cSBA) system. METHODS: We used a quasi-experimental, asynchronous study design in which each site served as its own control. From 2005 to 2008, 12- to 18-year-olds arriving for routine care at 9 medical offices in New England (n = 2096, 58% females) and 10 in Prague, Czech Republic (n = 589, 47% females) were recruited. Patients completed measurements only during the initial treatment-as-usual study phase. We then conducted 1-hour provider training, and initiated the cSBA phase. Before seeing the provider, all cSBA participants completed a computerized screen, and then viewed screening results, scientific information, and true-life stories illustrating substance use harms. Providers received screening results and “talking points” designed to prompt 2 to 3 minutes of brief advice. We examined alcohol and cannabis use, initiation, and cessation rates over the past 90 days at 3-month follow-up, and over the past 12 months at 12-month follow-up. RESULTS: Compared with treatment as usual, cSBA patients reported less alcohol use at follow-up in New England (3-month rates 15.5% vs 22.9%, adjusted relative risk ratio [aRRR] = 0.54, 95% confidence interval 0.38–0.77; 12-month rates 29.3% vs 37.5%, aRRR = 0.73, 0.57–0.92), and less cannabis use in Prague (3-month rates 5.5% vs 9.8%, aRRR = 0.37, 0.17–0.77; 12-month rates 17.0% vs 28.7%, aRRR = 0.47, 0.32–0.71). CONCLUSIONS: Computer-facilitated screening and provider brief advice appears promising for reducing substance use among adolescent primary care patients. PMID:22566420

Conditional screening for ultra-high dimensional covariates with survival outcomes

Hong, Hyokyoung G.; Li, Yi

2017-01-01

Identifying important biomarkers that are predictive for cancer patients’ prognosis is key in gaining better insights into the biological influences on the disease and has become a critical component of precision medicine. The emergence of large-scale biomedical survival studies, which typically involve excessive number of biomarkers, has brought high demand in designing efficient screening tools for selecting predictive biomarkers. The vast amount of biomarkers defies any existing variable selection methods via regularization. The recently developed variable screening methods, though powerful in many practical setting, fail to incorporate prior information on the importance of each biomarker and are less powerful in detecting marginally weak while jointly important signals. We propose a new conditional screening method for survival outcome data by computing the marginal contribution of each biomarker given priorily known biological information. This is based on the premise that some biomarkers are known to be associated with disease outcomes a priori. Our method possesses sure screening properties and a vanishing false selection rate. The utility of the proposal is further confirmed with extensive simulation studies and analysis of a diffuse large B-cell lymphoma dataset. We are pleased to dedicate this work to Jack Kalbfleisch, who has made instrumental contributions to the development of modern methods of analyzing survival data. PMID:27933468

Perinatal depression is well recognised as a mental health condition but <50% of cases are identified by healthcare professionals in routine clinical practice. The Edinburgh Postnatal Depression Scale (EPDS) is often used to detect symptoms of postnatal depression in maternity and child services. The National Institute for Health and Care Excellence (NICE) recommends 2 'ultra-brief' case-finding questions (the Whooley questions) to aid identification of depression during the perinatal period, but this recommendation was made in the absence of any validation studies in a perinatal population. Limited research exists on the acceptability of these depression case-finding instruments and the cost-effectiveness of routine screening for perinatal depression. The diagnostic accuracy of the Whooley questions and the EPDS will be determined against a reference standard (the Client Interview Schedule-Revised) during pregnancy (around 20 weeks) and the early postnatal period (around 3-4 months post partum) in a sample of 379 women. Further outcome measures will assess a range of psychological comorbidities, health-related quality of life and resource utilisation. Women will be followed up 12 months postnatally. The sensitivity, specificity and predictive values of the Whooley questions and the EPDS will be calculated against the reference standard at 20 weeks pregnancy and 3-4 months post partum. Acceptability of the depression case-finding instruments to women and healthcare professionals will involve in-depth qualitative interviews. An existing decision analytic model will be adapted to determine the cost-effectiveness of routine screening for perinatal depression. This study is considered low risk for participants. Robust protocols will deal with cases where risk of depression, self-harm or suicide is identified. The protocol received favourable ethical opinion from the North East-York Research Ethics Committee (reference: 11/NE/0022). The study findings will be published in peer-reviewed journals and presented at relevant conferences. Published by the BMJ Publishing Group Limited.

Delirium diagnosis, screening and management

PubMed Central

Lawlor, Peter G.; Bush, Shirley H.

2014-01-01

Purpose of review Our review focuses on recent developments across many settings regarding the diagnosis, screening and management of delirium, so as to inform these aspects in the context of palliative and supportive care. Recent findings Delirium diagnostic criteria have been updated in the long-awaited Diagnostic Statistical Manual of Mental Disorders, fifth edition. Studies suggest that poor recognition of delirium relates to its clinical characteristics, inadequate interprofessional communication and lack of systematic screening. Validation studies are published for cognitive and observational tools to screen for delirium. Formal guidelines for delirium screening and management have been rigorously developed for intensive care, and may serve as a model for other settings. Given that palliative sedation is often required for the management of refractory delirium at the end of life, a version of the Richmond Agitation-Sedation Scale, modified for palliative care, has undergone preliminary validation. Summary Although formal systematic delirium screening with brief but sensitive tools is strongly advocated for patients in palliative and supportive care, it requires critical evaluation in terms of clinical outcomes, including patient comfort. Randomized controlled trials are needed to inform the development of guidelines for the management of delirium in this setting. PMID:25004177

The DSM-5 Dimensional Anxiety Scales in a Dutch non-clinical sample: psychometric properties including the adult separation anxiety disorder scale.

Möller, Eline L; Bögels, Susan M

2016-09-01

With DSM-5, the American Psychiatric Association encourages complementing categorical diagnoses with dimensional severity ratings. We therefore examined the psychometric properties of the DSM-5 Dimensional Anxiety Scales, a set of brief dimensional scales that are consistent in content and structure and assess DSM-5-based core features of anxiety disorders. Participants (285 males, 255 females) completed the DSM-5 Dimensional Anxiety Scales for social anxiety disorder, generalized anxiety disorder, specific phobia, agoraphobia, and panic disorder that were included in previous studies on the scales, and also for separation anxiety disorder, which is included in the DSM-5 chapter on anxiety disorders. Moreover, they completed the Screen for Child Anxiety Related Emotional Disorders Adult version (SCARED-A). The DSM-5 Dimensional Anxiety Scales demonstrated high internal consistency, and the scales correlated significantly and substantially with corresponding SCARED-A subscales, supporting convergent validity. Separation anxiety appeared present among adults, supporting the DSM-5 recognition of separation anxiety as an anxiety disorder across the life span. To conclude, the DSM-5 Dimensional Anxiety Scales are a valuable tool to screen for specific adult anxiety disorders, including separation anxiety. Research in more diverse and clinical samples with anxiety disorders is needed. © 2016 The Authors International Journal of Methods in Psychiatric Research Published by John Wiley & Sons Ltd. © 2016 The Authors International Journal of Methods in Psychiatric Research Published by John Wiley & Sons Ltd.

Optimizing Efficiency of Psychopathology Assessment through Quantitative Modeling: Development of a Brief Form of the Externalizing Spectrum Inventory

PubMed Central

Patrick, Christopher J.; Kramer, Mark D.; Krueger, Robert F.; Markon, Kristian E.

2014-01-01

The Externalizing Spectrum Inventory (ESI; Krueger, Markon, Patrick, Benning, & Kramer, 2007) provides for integrated, hierarchical assessment of a broad range of problem behaviors and traits in the domain of deficient impulse control. The ESI assesses traits and problems in this domain through 23 lower-order facet scales organized around three higher-order dimensions, reflecting general disinhibition, callous-aggression, and substance abuse. The full-form ESI contains 415 items, and a shorter form would be useful for questionnaire screening studies or multi-domain research protocols. The current work employed item response theory and structural modeling methods to create a 160-item brief form (ESI-bf) that provides for efficient measurement of the ESI’s lower-order facets and quantification of its higher-order dimensions either as scale-based factors or as item-based composites. The ESI-bf is recommended for use in research on psychological or neurobiological correlates of problems such as risk-taking, delinquency, aggression, and substance abuse, and studies of general and specific mechanisms that give rise to problems of these kinds.

Cervicogenic dizziness (CGD) is hard to diagnose as there is no objective test. Can a brief assessment tool be derived from the Dizziness Handicap Inventory (DHI) to assist in screening for CGD? Case-control study with split-sample analysis. 86 people with CGD and 86 people with general dizziness completed the DHI as part of the assessment of their dizziness. Descriptive statistics were used to assess how frequently each question on the DHI was answered 'yes' or 'sometimes' by participants with CGD and by participants with general dizziness. The questions that best discriminated between GCD and general dizziness were compiled into a brief assessment tool for CGD. Data from 80 participants (40 from each group) were used to generate a receiver operating characteristic (ROC) curve to establish a cut-off score for that brief assessment tool. Then, data from the remaining 92 participants were used to try to validate the diagnostic ability of the brief assessment tool using that cut-off score. Questions 1, 9 and 11 were the most discriminatory and were combined to form the brief assessment tool. The ROC curve indicated an optimal threshold of 9. The diagnostic ability of the brief assessment tool among the remaining 46 participants from each group was: sensitivity 77% (95% CI: 67 to 84), specificity 66% (56-75), positive likelihood ratio 2.28 (1.66-3.13), and negative likelihood ratio 0.35 (0.23-0.53). A brief assessment tool of three questions appears to be helpful in screening for CGD. Copyright © 2017. Published by Elsevier Ltd.

Traditional Chinese medicine consists of complex phytochemical constituents. Selecting appropriate analytical markers of traditional Chinese medicine is a critical step in quality control. Currently, the combination of fingerprinting and efficacy evaluation is considered as a useful method for screening active ingredients in complex mixtures. This study was designed to develop an orthogonal partial least squares model for screening bioactive quality control markers of QishenYiqi dripping pills based on the fingerprint-efficacy relationship. First, the chemical fingerprints of 49 batches of QishenYiqi dripping pill samples were established by ultra-high performance liquid chromatography coupled with a photodiode array detector. Second, ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry was exploited to systematically investigate the 36 copossessing fingerprint components in QishenYiqi dripping pills. The vascular protective activity of QishenYiqi dripping pills was determined by using a cell counting kit-8 assay. Finally, fingerprint-efficacy relationship was established by orthogonal partial least squares model. The results indicated that ten components exhibited strong correlation with vascular protective activity, and these were preliminarily screened as quality control markers. The present study provided a novel idea for the study of the pharmacodynamic material basis and quality evaluation of QishenYiqi dripping pills. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Objective Identifying persons with systemic lupus erythematosus (SLE) at risk for depression would facilitate the identification and treatment of an important comorbidity conferring additional risk for poor outcomes. The purpose of this study was to determine the utility of a brief screening measure, the Center for Epidemiologic Studies Depression Scale (CES-D), in detecting mood disorders in persons with SLE. Methods This cross-sectional study examined 150 persons with SLE. Screening cut points were empirically derived using threshold selection methods, and receiver operating characteristic curves were estimated. The empirically derived cut points of the CES-D were used as the screening measures and were compared to other commonly used CES-D cut points in addition to other commonly used methods to screen for depression. Diagnoses of major depressive disorder or other mood disorders were determined using a “gold standard” structured clinical interview. Results Of the 150 persons with SLE, 26% of subjects met criteria for any mood disorder and 17% met criteria for major depressive disorder. Optimal threshold estimations suggested a CES-D cut score of 24 and above, which yielded adequate sensitivity and specificity in detecting major depressive disorder (88% and 93%, respectively) and correctly classified 92% of participants. To detect the presence of any mood disorder, a cut score of 20 and above was suggested, yielding sensitivity and specificity of 87% and correctly classifying 87%. Conclusion These results suggest the CES-D may be a useful screening measure to identify patients at risk for depression. PMID:21312347

Intensity mapping of the neutral hydrogen brightness temperature promises to provide a three-dimensional view of the universe on very large scales. Nonlinear effects are typically thought to alter only the small-scale power, but we show how they may bias the extraction of cosmological information contained in the power spectrum on ultra-large scales. For linear perturbations to remain valid on large scales, we need to renormalize perturbations at higher order. In the case of intensity mapping, the second-order contribution to clustering from weak lensing dominates the nonlinear contribution at high redshift. Renormalization modifies the mean brightness temperature and therefore the evolutionmore » bias. It also introduces a term that mimics white noise. These effects may influence forecasting analysis on ultra-large scales.« less

Acoustic droplet ejection (ADE) as a means of transferring library compounds has had a dramatic impact on the way in which high-throughput screening campaigns are conducted in many laboratories. Two Labcyte Echo ADE liquid handlers form the core of the compound transfer operation in our 1536-well based ultra-high-throughput screening (uHTS) system. Use of these instruments has promoted flexibility in compound formatting in addition to minimizing waste and eliminating compound carryover. We describe the use of ADE for the generation of assay-ready plates for primary screening as well as for follow-up dose-response evaluations. Custom software has enabled us to harness the information generated by the ADE instrumentation. Compound transfer via ADE also contributes to the screening process outside of the uHTS system. A second fully automated ADE-based system has been used to augment the capacity of the uHTS system as well as to permit efficient use of previously picked compound aliquots for secondary assay evaluations. Essential to the utility of ADE in the high-throughput screening process is the high quality of the resulting data. Examples of data generated at various stages of high-throughput screening campaigns are provided. Advantages and disadvantages of the use of ADE in high-throughput screening are discussed. © 2015 Society for Laboratory Automation and Screening.

Substantial empirical support exists for alcohol screening, brief intervention, and referral to treatment (SBIRT) in medical, but not non-medical settings such as the workplace. Workplace settings remain underutilised for delivering evidenced-based health services. This research aims to translate medical research into behavioural health-care practice in a telephonic call centre acting as a point of entry into an Employee Assistance Program (EAP). The goal of the study is to examine the feasibility of implementing routine telephonic alcohol SBIRT in an EAP call centre and assess whether routine SBIRT results in increased identification of workers who misuse alcohol. The design was pretest-posttest, one-group, pre-experimental. An alcohol SBIRT program developed based on World Health Organization recommendations was implemented in one EAP call centre serving one large employer. Workers were offered screening using the Alcohol Use Disorder Identification Test (AUDIT) during intake, brief counselling using motivational interviewing, referral to counselling, and follow-up. At 5 months, 93% of workers contacting the EAP completed the AUDIT-C: 40% prescreened positive and 52% went on to screen at moderate or high risk for an alcohol problem. Overall identification rate (18%) approached general US population estimates. Most agreed to follow-up and three-quarters set an appointment for face-to-face counselling. Integration of routine alcohol SBIRT into EAP practice is feasible in telephonic delivery systems and increases identification and opportunity for brief motivational counselling. When SBIRT is seamlessly integrated workers are willing to answer questions about alcohol and participate in follow-up.[McPherson TL, Goplerud E, Derr D, Mickenberg J, Courtemanche S.

Context: Deficits in social skills may present in a range of psychiatric disorders, particularly in the more serious and persistent conditions, and have an influence on functioning across various domains. Aims: This pilot study aimed at developing a brief measure, for structured evaluation and screening for social skills deficits, which can be easily integrated into routine clinical practice. Settings and Design: The sample consisted of 380 inpatients and their accompanying caregivers, referred to Psychiatric Rehabilitation Services at a tertiary care government psychiatric hospital. Materials and Methods: The evaluation included an Inpatient intake Proforma and the 20-item Social Skills Assessment Screening Scale (SSASS). Disability was assessed using the Indian Disability Evaluation and Assessment Scale (IDEAS) for a subset of 94 inpatients. Statistical Analysis Used: The analysis included means and standard deviations, frequency and percentages, Cronbach's alpha to assess internal consistency, t-tests to assess differences in social skills deficits between select subgroups, and correlation between SSASS and IDEAS scores. Results: The results indicated the profile of social skills deficits assessed among the inpatients with varied psychiatric diagnoses. The “psychosis” group exhibited significantly higher deficits than the “mood disorder” group. Results indicated high internal consistency of the SSASS and adequate criterion validity demonstrated by correlations with select IDEAS domains. Modifications were made to the SSASS following the pilot study. Conclusions: The SSASS has potential value as a measure for screening and individualised intervention plans for social skills training in mental health and rehabilitation settings. The implications for future work on the psychometric properties and clinical applications are discussed. PMID:27833220

The aim of this study was to assess the effectiveness of Screening and Brief Intervention (SBI) for alcohol problems among university students in South Africa. The study design for this efficacy study is a randomized controlled trial with 6- and 12-month follow-ups to examine the effects of a brief alcohol intervention to reduce alcohol use by hazardous and harmful drinkers in a university setting. The unit of randomization is the individual university student identified as a hazardous or harmful drinker attending public recruitment venues in a university campus. University students were screened for alcohol problems, and those identified as hazardous or harmful drinkers were randomized into an experimental or control group. The experimental group received one brief counseling session on alcohol risk reduction, while the control group received a health education leaflet. Results indicate that of the 722 screened for alcohol and who agreed to participate in the trial 152 (21.1%) tested positive for the Alcohol Use Disorder Identification Test (AUDIT) (score 8 or more). Among the 147 (96.7%) university students who also attended the 12-month follow-up session, the intervention effect on the AUDIT score was -1.5, which was statistically significant (P = 0.009). Further, the depression scores marginally significantly decreased over time across treatment groups, while other substance use (tobacco and cannabis use), self-rated health status and Posttraumatic Stress Disorder (PTSD) scores did not change over time across treatment groups. The study provides evidence of effective brief intervention by assistant nurses with hazardous and harmful drinkers in a university setting in South Africa. The short duration of the brief intervention makes it a realistic candidate for use in a university setting.

To compare a brief versus a brief plus intensive self-help version of 'Balance', a fully automated online alcohol intervention, on self-reported alcohol consumption. A pragmatic randomized controlled trial. Participants in both conditions received an online single session screening procedure including personalized normative feedback. The control group also received an online booklet about the effects of alcohol. The treatment group received the online multi-session follow-up program, Balance. Online study in Norway. At-risk drinkers were recruited by internet advertisements and assigned randomly to one of the two conditions (n = 244). The primary outcome was self-reported alcohol consumption the previous week measured 6 months after screening. Regression analysis, using baseline carried forward imputation (intent-to-treat), with baseline variables as covariates, showed that intervention significantly affected alcohol consumption at 6 months (B = 2.96; 95% confidence interval = 0.02-5.90; P = 0.049). Participants in the intensive self-help group drank an average of three fewer standard alcohol units compared with participants in the brief self-help group. The online Balance intervention, added to a brief online screening intervention, may aid reduction in alcohol consumption compared with the screening intervention and an educational booklet. © 2013 Society for the Study of Addiction.

As alcohol-related health problems continue to rise, the attention of policy-makers is increasingly turning to Screening and Brief Intervention (SBI) programmes. The effectiveness of such programmes in primary healthcare is well evidenced, but very few cost-effectiveness analyses have been conducted and none which specifically consider the Italian context. The Sheffield Alcohol Policy Model has been used to model the cost-effectiveness of government pricing and public health policies in several countries including England. This study adapts the model using Italian data to evaluate a programme of screening and brief interventions in Italy. Results are reported as Incremental Cost-Effectiveness Ratios (ICERs) of SBI programmes versus a 'do-nothing' scenario. Model results show such programmes to be highly cost-effective, with estimated ICERs of €550/Quality Adjusted Life Year (QALY) gained for a programme of SBI at next GP registration and €590/QALY for SBI at next GP consultation. A range of sensitivity analyses suggest these results are robust under all but the most pessimistic assumptions. This study provides strong support for the promotion of a policy of screening and brief interventions throughout Italy, although policy makers should be aware of the resource implications of different implementation options.

The ever-increasing need for enantiomerically pure chiral compounds has greatly expanded the number of enantioselective separation methods available for the precise and accurate measurements of the enantiomeric purity. The introduction of chiral stationary phases for liquid chromatography in the last decades has revolutionized the routine methods to determine enantiomeric purity of chiral drugs, agrochemicals, fragrances, and in general of organic and organometallic compounds. In recent years, additional efforts have been placed on faster, enantioselective analytical methods capable to fulfill the high throughput requirements of modern screening procedures. Efforts in this field, capitalizing on improved chromatographic particle technology and dedicated instrumentation, have led to highly efficient separations that are routinely completed on the seconds time scale. An overview of the recent achievements in the field of ultra-high-resolution chromatography on column packed with chiral stationary phases, both based on sub-2 μm fully porous and sub-3 μm superficially porous particles, will be given, with an emphasis on very recent studies on ultrafast chiral separations. © 2018 WILEY-VCH Verlag GmbH & Co.

The manual for the Japanese Stress Check Program recommends use of the Brief Job Stress Questionnaire (BJSQ) from among the program's instruments and proposes criteria for defining "high-stress" workers. This study aimed to examine how accurately the BJSQ identifies workers with or without potential psychological distress. We used an online survey to administer the BJSQ with a psychological distress scale (K6) to randomly selected workers (n=1,650). We conducted receiver operating characteristics curve analyses to estimate the screening performance of the cutoff points that the Stress Check Program manual recommends for the BJSQ. Prevalence of workers with potential psychological distress defined as K6 score ≥13 was 13%. Prevalence of "high-risk" workers defined using criteria recommended by the program manual was 16.7% for the original version of the BJSQ. The estimated values were as follows: sensitivity, 60.5%; specificity, 88.9%; Youden index, 0.504; positive predictive value, 47.3%; negative predictive value, 93.8%; positive likelihood ratio, 6.0; and negative likelihood ratio, 0.4. Analyses based on the simplified BJSQ indicated lower sensitivity compared with the original version, although we expected roughly the same screening performance for the best scenario using the original version. Our analyses in which psychological distress measured by K6 was set as the target condition indicate less than half of the identified "high-stress" workers warrant consideration for secondary screening for psychological distress.

Prospective memory difficulties are a feature of the amnestic form of mild cognitive impairment (aMCI). Although comprehensive test batteries of prospective memory are suitable for clinical practice, they are lengthy, which has detracted from their widespread clinical use. Our aim was to investigate the utility of a brief screening measure of prospective memory, which can be incorporated into a clinical neuropsychological assessment. Seventy-seven healthy older adults (HOA) and 77 participants with aMCI were administered a neuropsychological test battery, including a prospective memory screening measure (Envelope Task), a retrospective memory measure (CVLT-II), and a multi-item subjective memory questionnaire (Prospective and Retrospective Memory Questionnaire; PRMQ) and a single-item subjective memory scale. Compared with HOA participants, participants with aMCI performed poorly on the Envelope Task (η(2) = .38), which provided good discrimination of the aMCI and HOA groups (AUC = .83). In the aMCI group, there was a small but significant relationship between the Envelope Task and the single-item subjective rating of memory, with the Envelope Task accounting for 5-6% of the variance in subjective memory after accounting for emotional status. This relationship of prospective memory and subjective memory was not significant for the multi-item questionnaire (PRMQ); and, retrospective memory was not a significant predictor of self-rated memory, single-item, or multi-item. A brief screening measure of prospective memory, the Envelope Task, provides useful support to traditional memory measures in detecting aMCI.

PURPOSE We aimed to test whether 3 strategies—training and support, financial reimbursement, and an option to direct screen-positive patients to an Internet-based method of giving brief advice—have a longer-term effect on primary care clinicians’ delivery of screening and advice to heavy drinkers operationalized with the Alcohol Use Disorders Identification Test–Consumption (AUDIT-C) tool. METHODS We undertook a cluster randomized factorial trial with a 12-week implementation period in 120 primary health care units throughout Catalonia, England, Netherlands, Poland, and Sweden. Units were randomized to 8 groups: care as usual (control); training and support alone; financial reimbursement alone; electronic brief advice alone; paired combinations of these conditions; and all 3 combined. The primary outcome was the proportion of consulting adult patients (aged 18 years and older) receiving intervention—screening and, if screen-positive, advice—at 9 months. RESULTS Based on the factorial design, the ratio of the log of the proportion of patients given intervention at the 9-month follow-up was 1.39 (95% CI, 1.03–1.88) in units that received training and support as compared with units that did not. Neither financial reimbursement nor directing screen-positive patients to electronic brief advice led to a higher proportion of patients receiving intervention. CONCLUSIONS Training and support of primary health care units has a lasting, albeit small, impact on the proportion of adult patients given an alcohol intervention at 9 months. PMID:28694269

The two studies describe the development of three complementary scales to the Food Choice Questionnaire developed by Steptoe, Pollard & Wardle (1995). The new items address various ethical food choice motives and were derived from previous studies on vegetarianism and ethical food choice. The items were factor analysed in Study 1 (N=281) and the factor solution was confirmed in Study 2 (N=125), in which simple validity criteria were also included. Furthermore, test-retest reliability was assessed with a separate sample of subjects (N=36). The results indicated that the three new scales, Ecological Welfare (including subscales for Animal Welfare and Environment Protection), Political Values and Religion, are reliable and valid instruments for a brief screening of ethical food choice reasons.

Screening adolescents for substance use and intervening immediately can reduce the burden of addiction and substance-related morbidity. Several screening tools have been developed to identify problem substance use for adolescents, but none have been calibrated to triage adolescents into clinically relevant risk categories to guide interventions. To describe the psychometric properties of an electronic screen and brief assessment tool that triages adolescents into 4 actionable categories regarding their experience with nontobacco substance use. Adolescent patients (age range, 12-17 years) arriving for routine medical care at 2 outpatient primary care centers and 1 outpatient center for substance use treatment at a pediatric hospital completed an electronic screening tool from June 1, 2012, through March 31, 2013, that consisted of a question on the frequency of using 8 types of drugs in the past year (Screening to Brief Intervention). Additional questions assessed severity of any past-year substance use. Patients completed a structured diagnostic interview (Composite International Diagnostic Interview-Substance Abuse Module), yielding Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) substance use diagnoses. For the entire screen and the Screening to Brief Intervention, sensitivity and specificity for identifying nontobacco substance use, substance use disorders, severe substance use disorders, and tobacco dependence were calculated using the Composite International Diagnostic Interview-Substance Abuse Module as the criterion standard. Of 340 patients invited to participate, 216 (63.5%) enrolled in the study. Sensitivity and specificity were 100% and 84% (95% CI, 76%-89%) for identifying nontobacco substance use, 90% (95% CI, 77%-96%) and 94% (95% CI, 89%-96%) for substance use disorders, 100% and 94% (95% CI, 90%-96%) for severe substance use disorders, and 75% (95% CI, 52%-89%) and 98% (95% CI, 95%-100%) for nicotine dependence. No significant differences were found in sensitivity or specificity between the full tool and the Screening to Brief Intervention. A single screening question assessing past-year frequency use for 8 commonly misused categories of substances appears to be a valid method for discriminating among clinically relevant risk categories of adolescent substance use.

This project is to cool electrons in semiconductors to extremely low temperatures and to study new states of matter formed by low-dimensional electrons (or holes). At such low temperatures (and with an intense magnetic field), electronic behavior differs completely from ordinary ones observed at room temperatures or regular low temperature. Studies of electrons at such low temperatures would open the door for fundamental discoveries in condensed matter physics. Present studies have been focused on topological phases in the fractional quantum Hall effect in GaAs/AlGaAs semiconductor heterostructures, and the newly discovered (by this group) quantum spin Hall effect in InAs/GaSb materials.more » This project consists of the following components: 1) Development of efficient sample cooling techniques and electron thermometry: Our goal is to reach 1 mK electron temperature and reasonable determination of electron temperature; 2) Experiments at ultra-low temperatures: Our goal is to understand the energy scale of competing quantum phases, by measuring the temperature-dependence of transport features. Focus will be placed on such issues as the energy gap of the 5/2 state, and those of 12/5 (and possible 13/5); resistive signature of instability near 1/2 at ultra-low temperatures; 3) Measurement of the 5/2 gaps in the limit of small or large Zeeman energies: Our goal is to gain physics insight of 5/2 state at limiting experimental parameters, especially those properties concerning the spin polarization; 4) Experiments on tuning the electron-electron interaction in a screened quantum Hall system: Our goal is to gain understanding of the formation of paired fractional quantum Hall state as the interaction pseudo-potential is being modified by a nearby screening electron layer; 5) Experiments on the quantized helical edge states under a strong magnetic field and ultralow temperatures: our goal is to investigate both the bulk and edge states in a quantum spin Hall insulator under time-reversal symmetry-broken conditions.« less

Initial validation of the Nine Item Avoidant/Restrictive Food Intake disorder screen (NIAS): A measure of three restrictive eating patterns.

PubMed

Zickgraf, Hana F; Ellis, Jordan M

2018-04-01

Avoidant/Restrictive Food Intake Disorder (ARFID) is an eating or feeding disorder characterized by inadequate nutritional or caloric intake leading to weight loss, nutritional deficiency, supplement dependence, and/or significant psychosocial impairment. DSM-5 lists three different eating patterns that can lead to symptoms of ARFID: avoidance of foods due to their sensory properties (e.g., picky eating), poor appetite or limited interest in eating, or fear of negative consequences from eating. Research on the prevalence and psychopathology of ARFID is limited by the lack of validated instruments to measure these eating behaviors. The present study describes the development and validation of the nine-item ARFID screen (NIAS), a brief multidimensional instrument to measure ARFID-associated eating behaviors. Participants were 455 adults recruited on Amazon's Mechanical Turk, 505 adults recruited from a nationally-representative subject pool, and 311 undergraduates participating in research for course credit. Exploratory and confirmatory factor analyses provided evidence for three factors. The NIAS subscales demonstrated high internal consistency, test-retest reliability, invariant item loadings between two samples, and convergent/discriminant validity with other measures of picky eating, appetite, fear of negative consequences, and psychopathology. The scales were also correlated with measures of ARFID-like symptoms (e.g., low BMI, low fruit/vegetable variety and intake, and eating-related psychosocial interference/distress), although the picky eating, appetite, and fear scales had distinct independent relationships with these constructs. The NIAS is a brief, reliable instrument that may be used to further investigate ARFID-related eating behaviors. Copyright © 2017 Elsevier Ltd. All rights reserved.

Drosophila as a screening tool to study human neurodegenerative diseases.

2013-11-01

In an aging society, research involving neurodegenerative disorders is of paramount importance. Over the past few years, research on Alzheimer's and Parkinson's diseases has made tremendous progress. Experimental studies, however, rely mostly on transgenic animal models, preferentially using mice. Although experiments on mice have enormous advantages, they also have some inherent limitations, some of which can be overcome by the use of Drosophila melanogaster as an experimental animal. Among the major advantages of using the fly is its small genome, which can also be modified very easily. The fact that its genome lends itself to diverse alterations (e. g. mutagenesis, transposons) has made the fly a useful organism to perform large-scale and genome-wide screening approaches. This has opened up an entirely new field of experimental research aiming to elucidate genetic interactions and screen for modifiers of disease processes in vivo. Here, we provide a brief overview of how flies can be used to analyze molecular mechanisms underlying human neurodegenerative diseases. © 2013 International Society for Neurochemistry.

Community-Based Validation of the Social Phobia Screener (SOPHS).

Batterham, Philip J; Mackinnon, Andrew J; Christensen, Helen

2017-10-01

There is a need for brief, accurate screening scales for social anxiety disorder to enable better identification of the disorder in research and clinical settings. A five-item social anxiety screener, the Social Phobia Screener (SOPHS), was developed to address this need. The screener was validated in two samples: (a) 12,292 Australian young adults screened for a clinical trial, including 1,687 participants who completed a phone-based clinical interview and (b) 4,214 population-based Australian adults recruited online. The SOPHS (78% sensitivity, 72% specificity) was found to have comparable screening performance to the Social Phobia Inventory (77% sensitivity, 71% specificity) and Mini-Social Phobia Inventory (74% sensitivity, 73% specificity) relative to clinical criteria in the trial sample. In the population-based sample, the SOPHS was also accurate (95% sensitivity, 73% specificity) in identifying Diagnostic and Statistical Manual of Mental Disorders-Fifth edition social anxiety disorder. The SOPHS is a valid and reliable screener for social anxiety that is freely available for use in research and clinical settings.

For doping control, analyses of samples are generally achieved in two steps: a rapid screening and, in the case of a positive result, a confirmatory analysis. A two-step methodology based on ultra-high-pressure liquid chromatography coupled to a quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS) was developed to screen and confirm 103 doping agents from various classes (e.g., beta-blockers, stimulants, diuretics, and narcotics). The screening method was presented in a previous article as part I (i.e., Fast analysis of doping agents in urine by ultra-high-pressure liquid chromatography-quadrupole time-of-flight mass spectrometry. Part I: screening analysis). For the confirmatory method, basic, neutral and acidic compounds were extracted by a dedicated solid-phase extraction (SPE) in a 96-well plate format and detected by MS in the tandem mode to obtain precursor and characteristic product ions. The mass accuracy and the elemental composition of precursor and product ions were used for compound identification. After validation including matrix effect determination, the method was considered reliable to confirm suspect results without ambiguity according to the positivity criteria established by the World Anti-Doping Agency (WADA). Moreover, an isocratic method was developed to separate ephedrine from its isomer pseudoephedrine and cathine from phenylpropanolamine in a single run, what allowed their direct quantification in urine.

2016-08-01

Having a child admitted to intensive care is a highly stressful experience for parents; however there is a lack of screening instruments of parental stress in that context, which would be useful for both, research and clinical purposes. (1) To validate a brief measure of parental stress based on the Parental Stressor Scale: Paediatric Intensive Care Unit (PSS:PICU), (2) to study which environmental factors of the PICU are more stressful in a sample of Spanish parents, and (3) to study which variables are related to higher levels of stress among this group. 196 Spanish parents completed the Abbreviated PSS: PICU (A-PSS:PICU) and a general stress scale (the Perceived Stress Scale) upon their child's discharge to test the convergent validity of the tool. Three months later, they were assessed anxiety and depression using the Hospital Anxiety and Depression Scale, and posttraumatic stress with the Davidson Trauma Scale in order to test the predictive validity of the A-PSS:PICU. Two factors emerged from Confirmatory Factor Analyses, (1) stress due to child's condition and (2) stress related to PICU's staff. The A-PSS:PICU showed adequate reliability and convergent and predictive validity. The most stressful aspects were the behaviours and emotional responses of their child and the loss of their parental role. Age, gender, child's condition, length of admission, spiritual beliefs, and mechanical ventilation were associated to parental stress scores. The A-PSS:PICU is a reliable and valid measure. Parental stress should be screened during a child's PICU admission to identify parents at risk of post-discharge distress. Copyright © 2016 Australian College of Critical Care Nurses Ltd.

Our objective was to assess the effectiveness of three primary-care interventions to increase CRC screening participation among persons over the age of 50 years and to identify the health and socio-demographic-related factors that determine greater participation. We conducted a randomized experimental study with only one post-test control group. A total of 1,690 subjects were randomly distributed into four groups: written briefing; telephone briefing; an invitation to attend a group meeting; and no briefing. Subjects were evaluated 2 years post-intervention, with the outcome variable being participation in CRC screening. A total of 1,129 subjects were interviewed. Within the groups, homogeneity was tested in terms of socio-demographic characteristics and health-related variables. The proportion of subjects who participated in screening was: 15.4% in the written information group (95% confidence interval [CI]: 11.2-19.7); 28.8% in the telephone information group (95% CI: 23.6-33.9); 8.1% in the face-to-face information group (95% CI: 4.5-11.7); and 5.9% in the control group (95% CI: 2.9-9.0), with this difference proving statistically significant (p < 0.001). Logistic regression showed that only interventions based on written or telephone briefing were effective. Apart from type of intervention, number of reported health problems and place of residence remained in the regression model. Both written and telephone information can serve to improve participation in CRC screening. This preventive activity could be optimized by means of simple interventions coming within the scope of primary health-care professionals.

There is a particular need for valid scales to screen for posttraumatic stress disorder (PTSD) among women who seek safe shelter from intimate partner violence. Screening to identify women who are at risk for PTSD can lead to early intervention that reduces the risk for PTSD-related outcomes such as poor decision making, inconsistent parenting, and behavior dysfunction among their children. The gold standard for diagnosing PTSD is the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) (CAPS-5). A seven-item PTSD screen has been used for in this population and has a well-established cutoff score but has not been validated against the DSM-5 diagnostic criteria for PTSD. The study purpose was to establish concurrent validity for a seven-item screen for PTSD with the CAPS-5. Participants were 75 women, 18 years or older, who were residents of a 120-bed shelter in the southern United States. They spoke English or Spanish. They reported intimate partner physical or sexual violence within 4 months of their entry into the study. Following informed consent, data were collected in individual interviews, conducted in either English or Spanish. In addition to demographic data, the seven-item PTSD screen and the CAPS-5 were administered. A receiver operating characteristic (ROC) curve analysis was conducted to assess the concurrent validity of the seven-item PTSD screen with the CAPS-5. The seven-item PTSD screen results were significantly correlated with the CAPS-5 results in this sample (area under the curve [AUC] = .640, z = 2.670, p = .008). Sensitivity was 96.2, and observed specificity was 31.8. The seven-item PTSD screen demonstrates excellent sensitivity (e.g., 96% of true PTSD cases) and acceptable specificity (32% of non-PTSD cases) and can be used to quickly and accurately identify individuals for diagnostic assessment and intervention.

To evaluate the validity, reliability, and acceptability of the brief version of the self-management knowledge, attitude, and behavior (KAB) assessment scale for diabetes patients. Diabetes patients who were managed at the Xinkaipu Community Health Service Center of Tianxin in Changsha, Hunan Province were selected for survey by cluster sampling. A total of 350 diabetes patients were surveyed using the brief scale to collect data on knowledge, attitudes, and behaviors of self-management. Content validity was evaluated by Pearson correlation coefficient between the brief scale and subscales of knowledge, attitude, and behavior. Structure validity was evaluated by factor analysis, and discrimination validity was evaluated by an independent sample t-test between the high-score and low-score groups. Reliability was tested by internal consistency reliability and split-half reliability. The evaluation indexes of internal consistency reliability were Cronbach's α coefficients, θ coefficient, and Ω coefficient. Acceptability was evaluated by valid response rate and completion time of the brief scale. A total of 346(98.9%) valid questionnaires were returned, with average survey time of (11.43±3.4) minutes. Average score of the brief scale was 78.85 ± 11.22; scores of the knowledge, attitude, and behavior subscales were 16.45 ± 4.42, 21.33 ± 2.03, and 41.07 ± 8.34, respectively. Pearson correlation coefficients between the brief scale and the knowledge, attitude, and behavior subscales were 0.92, 0.42, and 0.60, respectively; P-values were all less than 0.01, indicating that the face validity and content validity of the brief scale were achieved to a good level. The common factor cumulative variance contribution rate of the brief scale and three subscales was from 53.66% to 61.75%, which achieved more than 50% of the approved standard. There were 11 common factors; 41 of the total 42 items had factor loadings above 0.40 in their relevant common factor, indicating that the brief scale and three subscales had good construct validity. Patients were divided into a high-score group and a low-score group, then scores of the brief scale and three subscales were compared between the groups using a t-test. The results were all significant, indicating that the brief scale and three subscales had good discriminate validity. Mean scores of the brief scale and three subscales of the high-score group were 91.55±6.81, 19.51±2.17, 22.74±1.88, and 49.30±6.20, respectively; these were higher than the low-score group (65.89±5.79, 12.29±4.76, 20.22±1.88, and 33.39±6.17, respectively) with t-values 27.76, 13.31, 9.20, and 17.56 (P-values were less than 0.001). The Cronbach's α coefficient, θ coefficient, Ω coefficient, and split-half reliability of the brief scale were 0.83, 0.87, 0.96, and 0.84, respectively. These values for the three subscales were all above 0.70, except for the θ coefficient of the attitude subscale with 0.64, indicating that the brief scale and three subscales had acceptable internal consistency reliability. The brief version of the diabetes self-management knowledge, attitude, and behavior assessment scale showed good acceptability, validity, and reliability, to responsibly evaluate self-management KAB among patients with diabetes.

Despite high rates of comorbidity between problem gambling and mental health disorders, few studies have examined barriers or facilitators to the implementation of screening for problem gambling in mental health services. This exploratory qualitative study identified key themes associated with screening in mental health services. Semi-structured interviews were undertaken with 30 clinicians and managers from 11 mental health services in Victoria, Australia. Major themes and subthemes were identified using qualitative content analysis. Six themes emerged including competing priorities, importance of routine screening, access to appropriate screening tools, resources, patient responsiveness and workforce development. Barriers to screening included a focus on immediate risk as well as gambling being often considered as a longer-term concern. Clinicians perceived problem gambling as a relatively rare condition, but did acknowledge the need for brief screening. Facilitators to screening were changes to system processes, such as identification of an appropriate brief screening instrument, mandating its use as part of routine screening, as well as funded workforce development activities in the identification and management of problem gambling.

XRIndex: a brief screening tool for individual differences in security threat detection in x-ray images

X-ray imaging is a cost-effective technique at security checkpoints that typically require the presence of human operators. We have previously shown that self-reported attention to detail can predict threat detection performance with small-vehicle x-ray images (Rusconi et al., 2012). Here, we provide evidence for the generality of such a link by having a large sample of naïve participants screen more typical dual-energy x-ray images of hand luggage. The results show that the Attention to Detail score from the autism-spectrum quotient (AQ) questionnaire (Baron-Cohen et al., 2001) is a linear predictor of threat detection accuracy. We then develop and fine-tune a novel self-report scale for security screening: the XRIndex, which improves on the Attention to Detail scale for predictive power and opacity to interpretation. The XRIndex is not redundant with any of the Big Five personality traits. We validate the XRIndex against security x-ray images with an independent sample of untrained participants and suggest that the XRIndex may be a useful aid for the identification of suitable candidates for professional security training with a focus on x-ray threat detection. Further studies are needed to determine whether this can also apply to trained professionals. PMID:26321935

The aim of this study was to design and evaluate a brief scale to assess adolescents' motivation to limit their screen-time using a self-determination theory (SDT) framework. The development and evaluation of the Motivation to Limit Screen-time Questionnaire (MLSQ) involved three phases. In Phase 1, experts in SDT were asked to review the content validity of the MLSQ items. In Phase 2, adolescent boys (N=342, mean age=12.7 ±.5 years) completed the MLSQ and the factorial validity of the model was explored. In Phase 3, adolescent boys (N=48, mean age=14.3 ± 1.3 years) completed the MLSQ on two occasions separated by 1-week. Phases 2 and 3 were conducted in New South Wales, Australia in 2012. Twenty four SDT experts reviewed the original scale items. Validity coefficients associated with six of the original eight items exceeded the threshold value (V>.68, p<.01). In Phase 2, the revised three-factor (9-items) model provided a good fit to the data (SRMR=.07, CFI=.96). The intraclass correlation (ICC) values were .67 for amotivation and .70 and .82 for controlled and autonomous motivation, respectively. This study has provided preliminary evidence for the validity and reliability of the MLSQ in adolescent boys. © 2013.

Low frequency electrostatic and electromagnetic waves are investigated in ultra-dense quantum magnetoplasma with relativistic-degenerate electron and non-degenerate ion fluids. The dispersion relation is derived for mobile as well as immobile ions by employing hydrodynamic equations for such plasma under the influence of electromagnetic forces and pressure gradient of relativistic-degenerate Fermi gas of electrons. The result shows the coexistence of shear Alfven and ion modes with relativistically modified dispersive properties. The relevance of results to the dense degenerate plasmas of astrophysical origin (for instance, white dwarf stars) is pointed out with brief discussion on ultra-relativistic and non-relativistic limits.

There are many available tools with varying levels of accuracy designed to screen for Autism Spectrum Disorder (ASD) in young children, both in the general population and specifically among those referred for developmental concerns. With burgeoning waitlists for comprehensive diagnostic ASD assessments, finding accurate methods and tools for advancing diagnostic triage becomes increasingly important. The current study compares the efficacy of four oft used paper and pencil measures, the Modified Checklist for Autism in Toddlers Revised with Follow-up, the Social Responsiveness Scale, Second Edition, and the Social Communication Questionnaire, and the Child Behavior Checklist to a novel mobile-health screening tool developed by Cognoa, Inc. (Cognoa) in a group of children 18-72 months of age. The Cognoa tool may have potential benefits as it integrates a series of parent-report questions with remote clinical ratings of brief video segments uploaded via parent's smartphones to calculate level of ASD risk. Participants were referred to one of three tertiary care diagnostic centers for ASD-related concerns (n = 230) and received a best estimate ASD diagnosis. Analysis and comparison of psychometric properties indicated potential advantages for Cognoa within this clinical sample across age ranges not often covered by another single measure/tool.

After a traumatic event many people experience problems with anger which not only results in significant distress, but can also impede recovery. As such, there is value to include the assessment of anger in routine post-trauma screening procedures. The Dimensions of Anger Reactions-5 (DAR-5), as a concise measure of anger, was designed to meet such a need, its brevity minimizing the burden on client and practitioner. This study examined the psychometric properties of the DAR-5 with a sample of 163 male veterans diagnosed with Posttraumatic Stress Disorder. The DAR-5 demonstrated internal reliability (α=.86), along with convergent, concurrent and discriminant validity against a variety of established measures (e.g., HADS, PCL, STAXI). Support for the clinical cut-point score of 12 suggested by Forbes et al. (2014, Utility of the dimensions of anger reactions-5 (DAR-5) scale as a brief anger measure. Depression and Anxiety, 31, 166-173) was observed. The results support considering the DAR-5 as a preferred screening and assessment measure of problematic anger. Copyright © 2014 Elsevier Ltd.

Risky drinking is associated with risky sexual experiences, however the relationship between alcohol and sex is complex. The aim of the study was to assess the feasibility of delivering alcohol screening and brief interventions in genitourinary medicine (GUM) clinics. The objectives were to; understand the levels of alcohol use amongst patients; report on the number of alcohol interventions delivered; and to analyse the relationship between alcohol use with demographic data as well as diagnosed sexually transmitted infections (STIs) to see if there were any associations. All new patients attending GUM between April 2012 and March 2013 self-completed the Alcohol Use Disorder Identification Test (AUDIT) prior to their clinical consultation. Where appropriate (scoring 8+ on AUDIT) the clinician would deliver up to 2-3 min of alcohol brief intervention. Descriptive statistics, t-tests, ANOVA and logistic regression were carried out as appropriate. AUDIT scores were available for 90% of all new patients (3058/3390) with an average mean score of 7.75. Of those who drank alcohol, 44% were categorised as being AUDIT positive, including 2% who had a score indicative of probable alcohol dependence (20+). 55 % (n = 638) of patients who screened positive on the AUDIT received a brief intervention whilst 24% (n = 674) of drinkers were diagnosed with a STI. Logistic regression modelling revealed that males, younger age groups and those of 'white' ethnicity were more likely to score positive on AUDIT. Patients classified as non-students, living in deprivation quintiles one to four and categorised as probable alcohol dependence on the AUDIT were more likely to be diagnosed with an STI. It is possible to embed alcohol screening into routine practice within sexual health services however further work is required to embed brief interventions particularly amongst increasing risk drinkers. If resources are limited, services may consider more targeted rather than universal alcohol screening to specific population groups. The study was undertaken in one GUM service in the North East of England and therefore findings may not be generalizable. The study did not assess efficacy of alcohol brief intervention in this setting.

The aim of the present study was to investigate the influence of suicide probability and relevant sociodemographic features and to provide information for preventing suicide in private security guards working under the stressful conditions and continuous exposure to the negative and traumatic life events. 200 private security guards and 200 personnels of Ankara University participated in the study. A sociodemographic information questionnaire, the Suicide Probability Scale (SPS) and the Brief Symptom Inventory (BSI) were used to collect the data. Gender, marital status, income, religious beliefs, experiencing a life-threatening situation, history of a suicide attempt, smoking and not having a chronic disease caused statistically significant differences in the scores for SPS between the private security guards group and the controls. Moreover there was a statistically significant positive correlation between the total scores of the subscales of SPS and the total scores of BSI. Like police officers and gendarmes, private security guards are at high risk of committing and attempting suicide because of being at stressful work settings and also suffering from secondary trauma. It is required that they should be aware of their tendency to commit suicide and have regular psychiatric screenings.

Educating physicians and other health care professionals about the identification and treatment of patients who drink more than recommended limits is an ongoing challenge. An educational randomized controlled trial was conducted to test the ability of a stand-alone training simulation to improve the clinical skills of health care professionals in alcohol screening and intervention. The "virtual reality simulation" combined video, voice recognition, and nonbranching logic to create an interactive environment that allowed trainees to encounter complex social cues and realistic interpersonal exchanges. The simulation included 707 questions and statements and 1207 simulated patient responses. A sample of 102 health care professionals (10 physicians; 30 physician assistants or nurse practitioners; 36 medical students; 26 pharmacy, physican assistant, or nurse practitioner students) were randomly assigned to a no training group (n = 51) or a computer-based virtual reality intervention (n = 51). Professionals in both groups had similar pretest standardized patient alcohol screening skill scores: 53.2 (experimental) vs 54.4 (controls), 52.2 vs 53.7 alcohol brief intervention skills, and 42.9 vs 43.5 alcohol referral skills. After repeated practice with the simulation there were significant increases in the scores of the experimental group at 6 months after randomization compared with the control group for the screening (67.7 vs 58.1; P < .001) and brief intervention (58.3 vs 51.6; P < .04) scenarios. The technology tested in this trial is the first virtual reality simulation to demonstrate an increase in the alcohol screening and brief intervention skills of health care professionals.

The Balance Evaluation Systems Test (BESTest) and its two abbreviated versions (mini-BESTest and briefBESTest) are functional balance tools that have yet to be validated in middle aged and elderly people living in the community. Determine the construct validity of the three BESTest versions by comparing them with commonly-used measures of balance, balance confidence and physical activity, and examining their ability to discriminate between groups with respect to falls and fall risk. This was a secondary analysis of data from 79 adults (mean age 68.7±10.57 years). Pearson correlation coefficients were used to examine the relationships between each BESTest measure and the Activities-Specific Balance Confidence (ABC) scale, the Physical Activity Scale for the Elderly (PASE), the Timed Up and Go (TUG) and the Single Leg Stance (SLS) test. Independent t-tests were used to examine differences in balance between fallers (≥1 fall in previous year) and non-fallers and individuals classified at low versus high fall risk using the Elderly Falls Screening Test (EFST). The BESTest measures showed moderate associations with the ABC scale and TUG (r=0.62-0.67 and -0.60 to -0.68 respectively), fair associations (r=0.33-0.40) with the PASE and moderate to high associations (r=0.67-0.77) with the SLS. Fallers showed a trend (p=0.054) for lower scores on the original BESTest, and people at high risk for falls had significantly lower scores on all BESTest versions. These findings support the construct validity of the BESTest, mini-BESTest and briefBESTest in adults over 50 years old. Copyright © 2015 Elsevier B.V. All rights reserved.

Ultra-high frequency ultrasound biomicroscopy and high throughput cardiovascular phenotyping in a large scale mouse mutagenesis screen

Ultrasound biomicroscopy (UBM) is ideally suited for phenotyping fetal mice for congenital heart disease (CHD), as imaging can be carried out noninvasively to provide both hemodynamic and structural information essential for CHD diagnosis. Using the UBM (Vevo 2100; 40Hz) in conjunction with the clinical ultrasound system (Acuson Sequioa C512; 15Hz), we developed a two-step screening protocol to scan thousands fetuses derived from ENU mutagenized pedigrees. A wide spectrum of CHD was detected by the UBM, which were subsequently confirmed with follow-up necropsy and histopathology examination with episcopic fluorescence image capture. CHD observed included outflow anomalies, left/right heart obstructive lesions, septal/valvular defects and cardiac situs anomalies. Meanwhile, various extracardiac defects were found, such as polydactyly, craniofacial defects, exencephaly, omphalocele-cleft palate, most of which were associated with cardiac defects. Our analyses showed the UBM was better at assessing cardiac structure and blood flow profiles, while conventional ultrasound allowed higher throughput low-resolution screening. Our study showed the integration of conventional clinical ultrasound imaging with the UBM for fetal mouse cardiovascular phenotyping can maximize the detection and recovery of CHD mutants.

This article reports on the test-retest reliability and sensitivity to change of a set of brief dimensional self-rating questionnaires for social anxiety disorder (SAD-D), specific phobia (SP-D), agoraphobia (AG-D), panic disorder (PD-D), and generalized anxiety disorder (GAD-D), as well as a general cross-cutting anxiety scale (Cross-D), which were developed to supplement categorical diagnoses in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). The German versions of the dimensional anxiety scales were administered to 218 students followed up approximately 2 weeks later (Study 1) and 55 outpatients (23 with anxiety diagnoses) followed-up 1 year later (Study 2). Probable diagnostic status in students was determined by the DIA-X/M-CIDI stem screening-questionnaire (SSQ). In the clinical sample, Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) diagnoses were assessed at Time 1 using the DIA-X/M-CIDI. At Time 2, the patient-version of the Clinical Global Impression-Improvement scale (CGI-I) was applied to assess change. Good psychometric properties, including high test-retest reliability, were found for the dimensional scales except for SP-D. In outpatients, improvement at Time 2 was associated with significant decrease in PD-D, GAD-D, and Cross-D scores. Discussion Major advantages of the scales include that they are brief, concise, and based on a consistent template to measure the cognitive, physiological, and behavioral symptoms of fear and anxiety. Further replication in larger samples is needed. Given its modest psychometric properties, SP-D needs refinement. Increasing evidence from diverse samples suggests clinical utility of the dimensional anxiety scales.

Brief alcohol interventions are recommended for primary care patients who screen positive for alcohol misuse, but implementation is challenging. The U.S. Veterans Health Administration (Veterans Affairs [VA]) implemented brief interventions for patients with alcohol misuse in 2008, and rates of brief interventions documented in the electronic medical record increased from 24% to 78% (2008-2011). This study examined whether an independent measure of brief interventions-patient-reported alcohol-related advice-also increased among VA outpatients who screened positive for alcohol misuse on a mailed survey. This retrospective cross-sectional study included VA outpatient respondents to the VA's Survey of Healthcare Experiences of Patients (SHEP; 2007-2011) who reported past-year alcohol use and answered a question about alcohol-related advice. Alcohol-related advice was defined as a report of past-year advice from a VA clinician to abstain from or reduce drinking. The adjusted prevalence of alcoholrelated advice among patients who screened positive for alcohol misuse (SHEP AUDIT-C ≥ 5) was estimated for each year. Among patients with alcohol misuse (n = 61,843), the adjusted prevalence of alcohol-related advice increased from 40.4% (95% CI [39.3%, 41.5%]) in 2007 to 55.5% (95% CI [53.3%, 57.8%]) in 2011. Rates of alcoholrelated advice increased significantly each year except the last. The VA's efforts to implement brief interventions were associated with increased patient-reported alcohol-related advice over time, with a majority of patients with alcohol misuse reporting its receipt. Other systems considering similar approaches to implementation may benefit from collecting patient-reported measures of brief interventions for an additional perspective on implementation.

To test the feasibility of a systemised ABC alcohol screening and brief intervention (SBI) approach in general practice in a New Zealand region. Data were collected on patients over 15 years who had their alcohol status recorded using the AUDIT tool. A concurrent independent process evaluation was conducted to assess effectiveness of ABC alcohol SBI related training and implementation of intervention. In an 8-month period, general practices in the Whanganui region documented alcohol consumption of 43% of their patients. Of the 43% of patients screened 24% were drinking contrary to ALAC's low risk drinking advice. Of these, 36% received brief advice or referral. Success of the approach can be attributed to the use of the Patient Dashboard reminder software and linked alcohol recording form. Other success factors included the use of a clinical champion and project leader, education and training, funding for extra GP and nurse assessment time and linking of the ABC alcohol SBI approach to existing services. Primary care in Whanganui has demonstrated the capacity to routinely query patient alcohol use and offer brief advice. If the approach was more widely adopted, there is considerable scope for general practice nationally to address potentially harmful patient alcohol use.

Objective To assess the structural overlap between the Behavior Rating Inventory of Executive Function (BRIEF) and Achenbach Child Behavior Check List (CBCL) among children in Uganda. Methods Caregiver ratings for the BRIEF and CBCL were obtained for two independent samples of school-aged children: 106 children (5-12 years old, 50% males) with a history of severe malaria, and on 144 HIV-infected children (5-12 years old, 58% males) in Uganda. Exploratory factor analysis was used to evaluate the factor structure of the 8 sub-scales for the BRIEF and the 8 scales of the CBCL to determine correlation. Results Overall, children in the severe malaria group had higher (increased symptom) BRIEF and CBCL scores than children in the HIV-infected group. We identified 3 factors that provided a reasonable fit to the data and could be characterized as 3 specific domains: 1) Metacognition, which consisted of the scales in the BRIEF Metacognition domain; 2) Behavioral Adjustment, which was comprised of the scales in the BRIEF Behavioral Regulation domain and the Externalizing Symptoms scales in the CBCL; and 3) Emotional Adjustment, which mainly consisted of the Internalizing Symptoms scales in the CBCL. The BRIEF Behavior Regulation and CBCL Externalizing Symptoms scales, however, did overlap in terms of assessing similar behavior symptoms. These findings were consistent across the severe malaria and HIV-infected samples of children. Conclusion The BRIEF and CBCL instruments offer distinct, yet complementary, assessments of behavior in clinical pediatric populations in the Ugandan context, supporting the use of these measures for similar research settings.

The European level of alcohol consumption, and the subsequent burden of disease, is high compared to the rest of the world. While screening and brief interventions in primary healthcare are cost-effective, in most countries they have hardly been implemented in routine primary healthcare. In this study, we aim to examine the effectiveness and efficiency of three implementation interventions that have been chosen to address key barriers for improvement: training and support to address lack of knowledge and motivation in healthcare providers; financial reimbursement to compensate the time investment; and internet-based counselling to reduce workload for primary care providers. In a cluster randomized factorial trial, data from Catalan, English, Netherlands, Polish, and Swedish primary healthcare units will be collected on screening and brief advice rates for hazardous and harmful alcohol consumption. The three implementation strategies will be provided separately and in combination in a total of seven intervention groups and compared with a treatment as usual control group. Screening and brief intervention activities will be measured at baseline, during 12 weeks and after six months. Process measures include health professionals' role security and therapeutic commitment of the participating providers (SAAPPQ questionnaire). A total of 120 primary healthcare units will be included, equally distributed over the five countries. Both intention to treat and per protocol analyses are planned to determine intervention effectiveness, using random coefficient regression modelling. Effective interventions to implement screening and brief interventions for hazardous alcohol use are urgently required. This international multi-centre trial will provide evidence to guide decision makers.

This study assessed the validity, sensitivity, and specificity of the Substance Use Risk Profile Scale (SURPS), a measure of personality risk factors for substance use and other behavioral problems in adolescence. The concurrent and predictive validity of the SURPS was tested in a sample of 1,162 adolescents (mean age: 13.7 years) using linear and logistic regressions, while its sensitivity and specificity were examined using the receiver operating characteristics curve analyses. Concurrent and predictive validity tests showed that all 4 brief scales-hopelessness (H), anxiety sensitivity (AS), impulsivity (IMP), and sensation seeking (SS)-were related, in theoretically expected ways, to measures of substance use and other behavioral and emotional problems. Results also showed that when using the 4 SURPS subscales to identify adolescents "at risk," one can identify a high number of those who developed problems (high sensitivity scores ranging from 72 to 91%). And, as predicted, because each scale is related to specific substance and mental health problems, good specificity was obtained when using the individual personality subscales (e.g., most adolescents identified at high risk by the IMP scale developed conduct or drug use problems within the next 18 months [a high specificity score of 70 to 80%]). The SURPS is a valuable tool for identifying adolescents at high risk for substance misuse and other emotional and behavioral problems. Implications of findings for the use of this measure in future research and prevention interventions are discussed. Copyright © 2012 by the Research Society on Alcoholism.

Anxiety and depression following traumatic brain injury (TBI) are associated with poorer outcomes. A brief self-report questionnaire would assist in identifying those at risk, however validity of such measures is complicated by confounding symptoms of the injury. This study investigated the validity of the Depression Anxiety Stress Scales (DASS) and Hospital Anxiety and Depression Scale (HADS), in screening for clinical diagnoses of anxiety and mood disorders following TBI. One hundred and twenty-three participants with mild to severe TBI were interviewed using the SCID (Axis I) and completed the DASS and HADS. The DASS, DASS21 and HADS scales demonstrated validity compared with SCID diagnoses of anxiety and mood disorders as measured by Area Under ROC Curve, sensitivity and specificity. Validity of the DASS depression scale benefited from items reflecting symptoms of devaluation of life, self-deprecation, and hopelessness that are not present on the HADS. Validity of the HADS anxiety scale benefited from items reflecting symptoms of tension and worry that are measured separately for the DASS on the stress scale. Participants were predominantly drawn from a rehabilitation centre which may limit the extent to which results can be generalized. Scores for the DASS21 were derived from the DASS rather than being administered separately. The DASS, DASS21 and HADS demonstrated validity as screening measures of anxiety and mood disorders in this TBI sample. The findings support use of these self-report questionnaires for individuals with TBI to identify those who should be referred for clinical diagnostic follow-up. © 2013 Elsevier B.V.

Introduction Functional abdominal pain (FAP) is associated with significant anxiety and impairment. Prior investigations of child anxiety in youth with FAP are generally limited by small sample sizes, based on child report, and use lengthy diagnostic tools. It is unknown 1) if a brief anxiety screening tool is feasible, 2) whether parent and child reports of anxiety are congruent, and 3) whether parent and child agreement of child anxiety corresponds to increased impairment. The purpose of this investigation was to examine anxiety characteristics in youth with FAP using parent and child reports. Parent-child agreement of child anxiety symptoms was examined in relation to pain and disability. Materials and Methods One-hundred patients with FAP (8-18 years of age) recruited from pediatric gastroenterology clinics completed measures of pain intensity (Numeric Rating Scale), and disability (Functional Disability Inventory). Patients and caregivers both completed a measure of child anxiety characteristics (Screen for Child Anxiety and Related Disorders). Results Clinically significant anxiety symptoms were more commonly reported by youth (54%) than their parents (30%). Panic/somatic symptoms, generalized anxiety, and separation anxiety were most commonly endorsed by patients whereas generalized anxiety, separation anxiety, and school avoidance were most commonly reported by parents. The majority (65%) of parents and children agreed on presence (26%) or absence (39%) of clinically significant anxiety. Parent-child agreement of clinically significant anxiety was related to increased impairment. Discussion A brief screening instrument of parent and child reports of anxiety can provide clinically relevant information for comprehensive treatment planning in children with FAP. PMID:25714575

Objective Identify the prevalence and clinical correlates of cognitive impairment in patients presenting for treatment of head and neck cancer (HNC) using brief screening within a multidisciplinary care team. Study Design A case series with planned data collection of cognitive function, quality of life (QoL), and psychosocial variables. Setting Urban Midwest academic medical center. Subjects and Methods In total, 209 consecutive patients with a diagnosis of HNC between August 2015 and September 2016 who had a pretreatment assessment with a clinical health psychologist. At pretreatment assessment, the Montreal Cognitive Assessment (MoCA), a brief screening tool for cognitive function, was administered along with a semistructured interview to gather information on psychiatric symptoms, social support, and substance use. Patient information, including demographics, clinical variables, and psychosocial variables, was extracted via chart review. A subset of patients with HNC completed the Functional Assessment of Cancer Therapy-Head and Neck Cancer at pretreatment assessment and was included in the QoL analyses. Results Cognitive impairment was associated with current alcohol use, past tobacco use and number of pack years, time in radiotherapy, and adherence to treatment recommendations. Social, emotional, and functional QoL scales were associated with cognitive impairment, including executive function, language, and memory. Conclusion Cognitive impairment is common in patients with HNC, and there are important associations between cognitive impairment and psychosocial, QoL, and treatment adherence variables. The results argue for the incorporation of cognitive screening as part of pretreatment assessment for patients, as well as further research into more direct, causal relationships via longitudinal, prospective studies.

Introduction Suboptimal screening for diabetic eye disease is a major cause of preventable vision loss. Screening barriers include mydriasis and the extra time patients need to attend dedicated eye screening appointments. In the Clearsight trial, we are testing whether screening by non-mydriatic ultra-wide field (NM UWF) imaging on the day patients attend their diabetes outpatient clinic visit improves detection of clinically important eye disease compared with usual screening. Methods and analysis Patients with diabetes due for a screening eye exam by the 2013 Canadian Diabetes Association (CDA) practice guidelines are being randomised to on-site screening by NM UWF imaging on the day of their clinic visit or to usual screening where, per CDA guidelines, they are encouraged to arrange an exam by an optometrist. The primary outcome is actionable eye disease (AED) based on a need for referral to ophthalmology and/or increased ocular surveillance. The primary analysis will use an intention-to-screen approach that compares the proportions of detected AED between on-site and usual screening groups under a superiority hypothesis in favour of on-site screening. With 740 randomised participants, the study will have 80% power to detect ≥5% absolute increase in the AED rate among on-site screening versus usual screening participants. This difference translates into a number-needed-to-screen by on-site screening of 20 to detect 1 additional person with AED. Ethics and dissemination The protocol was approved by the institutional review board of Western University. The findings of the trial will be disseminated directly to participants and through peer-reviewed publications and conference presentations. Trial registration number ClinicalTrials.Gov NCT02579837 (registered 16 October 2015). Protocol issue date 18 November 2015. PMID:28775182

An infrared spectroscopic technique based on planar array infrared (PAIR) spectroscopy has been developed that allows the acquisition of spectra from multiple samples simultaneously. Using this technique, it is possible to acquire spectra over a spectral range of 950–1900cm−1 with a temporal resolution of 2.2ms. The performance of this system was demonstrated by determining the shear-induced orientational response of several low molecular weight liquid crystals. Five different liquid crystals were examined in combination with five different alignment layers, and both primary and secondary screens were demonstrated. Implementation of this high throughput PAIR technique resulted in a reduction in acquisition time as compared to both step-scan and ultra-rapid-scanning FTIR spectroscopy. PMID:19239197

Preparing nursing students to apply an evidence-based screening and brief intervention approach with patients has the potential to reduce patients' risky alcohol and drug use. Responding to Mollica, Hyman, and Mann's article published in 2011, the current article describes implementation results of an Addiction Training for Nurses program of Screening, Brief Intervention, and Referral to Treatment (SBIRT) embedded within an undergraduate nursing curriculum. Results reveal that students in other schools of nursing would benefit from similar, significant training on substance use disorders and SBIRT. Training satisfaction surveys (N = 488) indicate students were satisfied with the quality of the training experience. More than 90% of students strongly agreed or agreed that the training was relevant to their nursing careers and would help their patients. Additional clinical practice and skill development may increase students' reported effectiveness in working with the topic area of substance use and SBIRT. Copyright 2013, SLACK Incorporated.

PURPOSE We undertook a study to compare 3 ways of administering brief domestic violence screening questionnaires: self-administered questionnaire, medical staff interview, and physician interview. METHODS We conducted a randomized trial of 3 screening protocols for domestic violence in 4 urban family medicine practices with mostly minority patients. We randomly assigned 523 female patients, aged 18 years or older and currently involved with a partner, to 1 of 3 screening protocols. Each included 2 brief screening tools: HITS and WAST-Short. Outcome measures were domestic violence disclosure, patient and clinician comfort with the screening, and time spent screening. RESULTS Overall prevalence of domestic violence was 14%. Most patients (93.4%) and clinicians (84.5%) were comfortable with the screening questions and method of administering them. Average time spent screening was 4.4 minutes. Disclosure rates, patient and clinician comfort with screening, and time spent screening were similar among the 3 protocols. In addition, WAST-Short was validated in this sample of minority women by comparison with HITS and with the 8-item WAST. CONCLUSIONS Domestic violence is common, and we found that most patients and clinicians are comfortable with domestic violence screening in urban family medicine settings. Patient self-administered domestic violence screening is as effective as clinician interview in terms of disclosure, comfort, and time spent screening. PMID:17893385

Amid numerous complications that plague the health and quality of life of people living with HIV, neurocognitive and psychiatric illnesses pose unique challenges. While there remains uncertainty with respect to the pathophysiology surrounding these disorders, their adverse implications are increasingly recognized. Left undetected, they have the potential to significantly impact patient well being, adherence to antiretroviral treatment and overall health outcomes. As such, early identification of HIV-associated neurocognitive disorders (HAND) and psychiatric illnesses will be paramount in the proactive management of affected patients. The present review focuses on strategies to ensure optimal screening and detection of HAND, depression and substance abuse in routine practice. For each topic, currently available screening methods are discussed. These include identification of risk factors, recognition of relevant symptomatology and an update on validated screening tools that can be efficiently implemented in the clinical setting. Specifically addressed in the present review are the International HIV Dementia Scale, a novel screening equation and algorithm for HAND, as well as brief, validated, verbal questionnaires for detection of depression and substance abuse. Adequate understanding and usage of these screening mechanisms can ensure effective use of resources by distinguishing patients who require referral for more extensive diagnostic procedures from those who likely do not.

Glucose oxidase (GOx) is used in many industrial processes that could benefit from improved versions of the enzyme. Some improvements like higher activity under physiological conditions and thermal stability could be useful for GOx applications in biosensors and biofuel cells. Directed evolution is one of the currently available methods to engineer improved GOx variants. Here, we describe an ultra-high-throughput screening system for sorting the best enzyme variants generated by directed evolution that incorporates several methodological refinements: flow cytometry, in vitro compartmentalization, yeast surface display, fluorescent labeling of the expressed enzyme, delivery of glucose substrate to the reaction mixture through the oil phase, and covalent labeling of the cells with fluorescein-tyramide. The method enables quantitative screening of gene libraries to identify clones with improved activity and it also allows cells to be selected based not only on the overall activity but also on the specific activity of the enzyme.

Rates of posttraumatic stress disorder (PTSD) are high among women seeking treatment for substance use disorders (SUDs). Minority women, in particular, experience high rates of trauma and may be less likely to disclose trauma history. This article identifies items from pre-existing screening measures that can be used across settings to sensitively but noninvasively identify women with likely PTSD. For a sample of 104 African American women in residential SUD treatment who provided informed consent as a part of a larger randomized clinical trial, the prevalence of trauma and PTSD, as well as the relationships between trauma, health, depression, and distress, was examined. Measures included Posttraumatic Stress Diagnostic Scale (PDS), Center for Epidemiologic Studies-Depression Scale (CES-D), Pennebaker Inventory of Limbic Languidness (PILL), and Brief Symptom Inventory (BSI). Additional analyses were undertaken to determine if a subset of noninvasive items could serve to identify the presence of a probable PTSD diagnosis. Most women (94.2%) reported at least one lifetime trauma, with over half (51.0%) meeting DSM-IV criteria for PTSD. Women with greater trauma symptom severity reported more health problems and higher levels of depression and distress. Five BSI items and one CES-D item were significantly associated with a probable PTSD diagnosis with a sensitivity of 88.7%, a specificity of 66.7%, a positive predictive value of 73.4%, a negative predictive value of 85.0%, and an accuracy of 77.9%. Findings affirm that African American women with SUDs present for residential treatment with comorbid psychiatric and emotional conditions that warrant assessment and treatment. Results highlight potential benefits of brief screening with routine measures and coordinated access to ancillary psychiatric and medical services, in conjunction with substance treatment, such as in residential or primary care.

The Brief Anxiety and Depression Scale (BADS): a new instrument for detecting anxiety and depression in long-term care residents.

PubMed

Mansbach, William E; Mace, Ryan A; Clark, Kristen M

2015-04-01

Depression and anxiety are common among long-term care residents, yet both appear to be under-recognized and under-treated. In our survey of 164 geriatric health care professionals from 34 U.S. states, 96% of respondents reported that a new instrument that rapidly assesses both depression and anxiety is needed. The Brief Anxiety and Depression Scale (BADS) is a new screening tool that can identify possible major depressive episodes (MDE) and generalized anxiety disorders (GAD) in long-term care residents. The psychometric properties of the BADS were investigated in a sample of 224 U.S. long-term care residents (aged 80.52 ± 9.07). Participants completed a battery of several individually administered mood and cognitive tests, including the BADS. MDE and GAD were diagnosed based on the DSM-IV-TR criteria. Adequate internal consistency and construct validity were found. A principle component analysis (PCA) revealed an Anxiety Factor and a Depression Factor, which explained 50.26% of the total variance. The Anxiety Factor had a sensitivity of 0.73 and specificity of 0.81 for identifying GAD (PPV = 0.69, NPV = 0.84). The Depression Factor had a sensitivity of 0.76 and a specificity of 0.73 for identifying MDE (PPV = 0.77, NPV = 0.72). The BADS appears to be a reliable and valid screening instrument for MDE and GAD in long-term residents. The BADS can be rapidly administered, is sensitive to mood diagnoses in both patients without dementia and with dementia, and produces separate depression and anxiety factor scores that can be used clinically to identify probable mood diagnoses.

Computerized visuo-spatial memory test as a supplementary screening test for dementia.

2010-06-01

To prepare for a super-aging society, effective dementia screening tests are required. The most salient deficit appearing from the early stages of dementia/Alzheimer's disease (AD) is a deterioration in memory. The Hasegawa Dementia Scale-revised (HDS-R) and the Mini-Mental State Examination (MMSE) are widely used in Japan to screen for dementia. Both place an emphasis on memory function, but neither examines visuo-spatial memory (VSM) function, even though VSM deficits are a sensitive marker for the detection of conversion to dementia. Furthermore, brief tests of VSM that are appropriate for screening have not been standardized. Thus, in the present study, we devised a brief, computer-aided short-term VSM test. Sixty-six aged people were evaluated. Using the Clinical Dementia Rating (CDR), it was found that 29 could be considered normal controls (NC; CDR 0), 10 had mild cognitive impairment (MCI; CDR 0.5), 15 had mild dementia (CDR 1), and 12 had moderate to severe dementia (CDR 2-3). The VSM test estimated how many locations each subject could memorize. Several numbered circles were shown on a monitor and subjects were required to memorize the location of these circles sequentially. After the numbers on the circles on the screen had disappeared, the subjects were required to indicate the circles in ascending order. A touch panel screen was used for this test to make it easier. The HDS-R was applied to subjects with MCI and dementia. The mean (+/-SD) VSM score in subjects with MCI (5.70 +/- 0.96) was significantly lower than that in NC subjects (6.69 +/- 0.82), but significantly higher than that in subjects classified as CDR 1 (4.67 +/- 0.87). There was no significant difference in VSM scores between subjects classified as CDR 1 and CDR 2-3 (3.80 +/- 0.80). There was a moderate significant correlation between VSM and HDS-R scores. In the present study, the VSM test detected differences in VSM function among NC subjects and subjects with MCI and mild dementia. The software program for the VSM test is distributed for free so that it can be widely used.

In this paper, we test path models that study the interrelations between primary health care provider attitudes towards working with drinkers, their screening and brief advice activity, and their receipt of training and support and financial reimbursement. Study participants were 756 primary health care providers from 120 primary health care units (PHCUs) in different locations throughout Catalonia, England, The Netherlands, Poland, and Sweden. Our interventions were training and support and financial reimbursement to providers. Our design was a randomized factorial trial with baseline measurement period, 12-week implementation period, and 9-month follow-up measurement period. Our outcome measures were: attitudes of individual providers in working with drinkers as measured by the Short Alcohol and Alcohol Problems Perception Questionnaire; and the proportion of consulting adult patients (age 18+ years) who screened positive and were given advice to reduce their alcohol consumption (intervention activity). We found that more positive attitudes were associated with higher intervention activity, and higher intervention activity was then associated with more positive attitudes. Training and support was associated with both positive changes in attitudes and higher intervention activity. Financial reimbursement was associated with more positive attitudes through its impact on higher intervention activity. We conclude that improving primary health care providers’ screening and brief advice activity for heavy drinking requires a combination of training and support and on-the-job experience of actually delivering screening and brief advice activity.

Objective Prior studies have shown a low rate of accurate identification by primary care physicians of mental health disorders in youth. This study tested the psychometric properties of two brief mental health screening questionnaires, the Mood and Feelings Questionnaire – Short Form (MFQ-SF) and Childhood Anxiety Sensitivity Index (ASI), in a large sample of youth. Methods In a sample of 1375 youth age 11 to 17 (779 with asthma, 596 randomly selected controls) enrolled in an HMO, the psychometric properties (optimum cutoffs on Receiver Operating Curve (ROC) curves, sensitivity, specificity, positive and negative predictive values) of two brief anxiety and depression screens were examined versus a “gold standard” structured psychiatric interview. Results Both the MFQ-SF and ASI performed well on ROC analysis for screening youth for one or more DSM-IV anxiety or depressive disorders. The MFQ-SF performed better on ROC analysis than the ASI for youth with major depression (area under the curve of 0.84 vs 0.77). For screening youth with anxiety disorders ROC curves showed that both the MFQ-SF and ASI only performed in the fair range (area under the curve of 0.76). Conclusion The MFQ-SF and ASI are two relatively brief questionnaires that performed well for screening youth for one or more DSM-IV anxiety or depressive disorders. The MFQ-SF performed better than the ASI for screening youth with major depression. Use of these instruments could increase the accuracy of identification of mental health disorders in youth by primary care physicians. PMID:18501865

Screening and brief interventions (SBI) delivered in primary health care (PHC) are cost-effective in decreasing alcohol consumption; however, they are underused. This study aims to identify implementation strategies that focus on SBI uptake and measure impact on: (1) heavy drinking and (2) delivery of SBI in PHC. Meta-analysis was conducted of controlled trials of SBI implementation strategies in PHC to reduce heavy drinking. Key outcomes included alcohol consumption, screening, brief interventions and costs in PHC. Predictor measures concerned single versus multiple strategies, type of strategy, duration and physician-only input versus that including mid-level professionals. Standardized mean differences (SMD) were calculated to indicate the impact of implementation strategies on key outcomes. Effect sizes were aggregated using meta-regression models. The 29 included studies were of moderate methodological quality. Strategies had no overall impact on patients' reported alcohol consumption [SMD=0.07; 95% confidence interval (CI)=-0.02 to 0.16], despite improving screening (SMD=0.53; 95% CI=0.28-0.78) and brief intervention delivery (SMD=0.64;95% CI=0.27-1.02). Multi-faceted strategies, i.e. professional and/or organizational and/or patient-orientated strategies, seemed to have strongest effects on patients' alcohol consumption (P<0.05, compared with professional-orientated strategies alone). Regarding SBI delivery, combining professional with patient-orientated implementation strategies had the highest impact (P<0.05). Involving other staff besides physicians was beneficial for screening (P<0.05). To increase delivery of alcohol screening and brief interventions and decrease patients' alcohol consumption, implementation strategies should include a combination of patient-, professional- and organizational-orientated approaches and involve mid-level health professionals as well as physicians. © 2015 Society for the Study of Addiction.

Effectiveness of brief interventions as part of the Screening, Brief Intervention and Referral to Treatment (SBIRT) model for reducing the nonmedical use of psychoactive substances: a systematic review

PubMed Central

2014-01-01

Background The purpose of this systematic review is to assess the effectiveness of brief interventions (BIs) as part of the Screening, Brief Intervention, and Referral to Treatment (SBIRT) model for reducing the nonmedical use of psychoactive substances. Methods Bibliographic databases (including MEDLINE, Embase, The Cochrane Library, CINAHL, and PsycINFO to April 2012) and gray literature sources were searched. We included randomized controlled trials that opportunistically screened adolescents or adults and then provided a one-to-one, verbal BI to those at risk of substance-use harm. Of interest was the nonmedical use of psychoactive substances (for example, drugs prohibited by international law), excluding alcohol, nicotine, and caffeine. Interventions comprised four or fewer sessions and were compared with no/delayed intervention or provision of information only. Studies were assessed for bias using the Cochrane risk of bias tool. Results were synthesized narratively. Evidence was interpreted according to the GRADE framework. Results We identified 8,836 records. Of these, five studies met our inclusion criteria. Two studies compared BI with no BI, and three studies compared BI with information only. Studies varied in characteristics such as substances targeted, screening procedures, and BI administered. Outcomes were mostly reported by a single study, leading to limited or uncertain confidence in effect estimates. Conclusions Insufficient evidence exists as to whether BIs, as part of SBIRT, are effective or ineffective for reducing the use of, or harms associated with nonmedical use of, psychoactive substances when these interventions are administered to nontreatment-seeking, screen-detected populations. Updating this review with emerging evidence will be important. Trial registration CRD42012002414 PMID:24887418

A method of ultra high performance liquid chromatography-linear ion trap/orbitrap high resolution mass spectrometry (UPLC-LTQ/Orbitrap MS) was established to screen and confirm 24 hormones in cosmetics. Various cosmetic samples were extracted with methanol. The extract was loaded onto a Waters ACQUITY UPLC BEH C18 column (50 mm x 2.1 mm, 1.7 microm) using a gradient elution of acetonitrile/water containing 0.1% (v/v) formic acid for the separation. The accurate mass of quasi-molecular ion was acquired by full scanning of electrostatic field orbitrap. The rapid screening was carried out by the accurate mass of quasi-molecular ion. The confirmation analysis for targeted compounds was performed with the retention time and qualitative fragments obtained by data dependent scan mode. Under the optimal conditions, the 24 hormones were routinely detected with mass accuracy error below 3 x 10(-6) (3 ppm), and good linearities were obtained in their respective linear ranges with correlation coefficients higher than 0.99. The LODs (S/N = 3) of the 24 compounds were < or = 10 microg/kg, which can meet the requirements for the actual screening of cosmetic samples. The developed method was applied to screen the hormones in 50 cosmetic samples. The results demonstrate that the method is a useful tool for the rapid screening and identification of the hormones in cosmetics.

Screening, brief intervention, and referral to treatment (SBIRT) is recommended as a strategy to prevent or reduce adolescent substance use. Offering SBIRT in schools may provide an opportunity to reach adolescents not accessing primary care. The objective is to assess school nurses' attitudes and practices regarding adolescent SBIRT. The authors administered electronically and in person a questionnaire including 29 items on SBIRT attitudes and practices to school nurses registered for the Northeastern University's School Health Institute Summer Program in Massachusetts (N = 168). Survey questions were adapted from a questionnaire originally developed by the American Academy of Pediatrics. One hundred and forty-four nurses completed the survey for a response rate of 85.7%. More than three quarters of the respondents (77.0%) were in favor of universal alcohol screening in schools. None of the respondents reported screening their students on a regular basis. More than half (64.4%) of nurses reported screening students; however, they did so only when they suspected alcohol use. During these instances, only 17.9% used a validated screening tool and almost all (98.2%) used face-to-face clinical interviews. When addressing alcohol use by a student, the large majority of respondents reported including the following recommended clinical strategies: asking about problems related to alcohol use (56.3%), explaining the harms of alcohol use (70.1%), and advising abstinence (73.6%). On average, respondents spend 5 to 10 minutes discussing alcohol use with their students. Survey respondents were supportive of universal alcohol screening in school, although few were doing so at the time. When respondents identified students using alcohol, their interventions were closely aligned with clinical recommendations for brief intervention. Implementation of SBIRT that focuses on standardized, annual screening has the potential to deliver high-quality care in this setting.

A substantial body of research has established the effectiveness of brief interventions for problem alcohol use. Following these studies, national dissemination projects of screening, brief intervention (BI), and referral to treatment (SBIRT) for alcohol and drugs have been implemented on a widespread scale in multiple states despite little existing evidence for the impact of BI on drug use for non-treatment seekers. This article describes the design of a study testing the impact of SBIRT on individuals with drug problems, its contributions to the existing literature, and its potential to inform drug policy. The study is a randomized controlled trial of an SBIRT intervention carried out in a primary care setting within a safety net system of care. Approximately 1,000 individuals presenting for scheduled medical care at one of seven designated primary care clinics who endorse problematic drug use when screened are randomized in a 1:1 ratio to BI versus enhanced care as usual (ECAU). Individuals in both groups are reassessed at 3, 6, 9, and 12 months after baseline. Self-reported drug use and other psychosocial measures collected at each data point are supplemented by urine analysis and public health-related data from administrative databases. This study will contribute to the existing literature by providing evidence for the impact of BI on problem drug use based on a broad range of measures including self-reported drug use, urine analysis, admission to drug abuse treatment, and changes in utilization and costs of health care services, arrests, and death with the intent of informing policy and program planning for problem drug use at the local, state, and national levels.

The purpose of this study was to validate a patch-based image denoising method for ultra-low-dose CT images. Neural network with convolutional auto-encoder and pairs of standard-dose CT and ultra-low-dose CT image patches were used for image denoising. The performance of the proposed method was measured by using a chest phantom. Standard-dose and ultra-low-dose CT images of the chest phantom were acquired. The tube currents for standard-dose and ultra-low-dose CT were 300 and 10 mA, respectively. Ultra-low-dose CT images were denoised with our proposed method using neural network, large-scale nonlocal mean, and block-matching and 3D filtering. Five radiologists and three technologists assessed the denoised ultra-low-dose CT images visually and recorded their subjective impressions of streak artifacts, noise other than streak artifacts, visualization of pulmonary vessels, and overall image quality. For the streak artifacts, noise other than streak artifacts, and visualization of pulmonary vessels, the results of our proposed method were statistically better than those of block-matching and 3D filtering (p-values < 0.05). On the other hand, the difference in the overall image quality between our proposed method and block-matching and 3D filtering was not statistically significant (p-value = 0.07272). The p-values obtained between our proposed method and large-scale nonlocal mean were all less than 0.05. Neural network with convolutional auto-encoder could be trained using pairs of standard-dose and ultra-low-dose CT image patches. According to the visual assessment by radiologists and technologists, the performance of our proposed method was superior to that of large-scale nonlocal mean and block-matching and 3D filtering.

Development and psychometric analysis of the Brief DSM-5 Alcohol Use Disorder Diagnostic Assessment: Towards effective diagnosis in college students.

Hagman, Brett T

2017-11-01

The Diagnostic and Statistical Manual of Mental Disorders (5th edition) Alcohol Use Disorder (DSM-5 AUD) criteria have been modified to reflect a single, continuous disorder. It is critical that we develop brief assessment measures that can accurately assess for DSM-5 AUD criteria in college students to assist in screening, referral, and brief intervention services implemented on college campuses. The present study sought to develop and assess for the psychometric properties of a brief 13-item measure designed to capture the full spectrum of the DSM-5 AUD criteria in a sample of college students. Participants were past-year drinkers (N = 923) between the ages of 18 to 30 enrolled at 3 universities. Respondents completed a 30-min anonymous battery of questionnaires online. The Brief DSM-5 AUD Assessment consisted of 13 items designed to reflect the DSM-5 AUD criteria. Results indicated a high degree of internal consistency reliability with high item-to-scale correlations. Confirmatory factor analyses indicated that a dominant single factor emerged with good model fit. The Item Response Theory (IRT) analyses indicated that the difficulty parameters for each criterion were intermixed along the upper portion of the underlying AUD severity continuum, and the discrimination parameters were all high. Additional analysis indicated that those with a DSM-5 AUD had greater levels of alcohol and other drug use and problem severity in comparison to those without a DSM-5 AUD. Study findings provide empirical support for the reliability and validity of the Brief 13-item DSM-5 Assessment. It should be routinely included into research and clinical practice efforts.

To conduct a cost-effectiveness analysis (CEA) comparing the delivery of brief intervention (BI) with brief treatment (BT) within Screening, Brief Intervention and Referral to Treatment (SBIRT) programs. Quasi-experimental differences in observed baseline characteristics between BI and BT patients were adjusted using propensity score techniques. Incremental comparison of costs and health outcomes associated with BI and BT. Health-care settings in four US states participating in Substance Abuse and Mental Health Services Administration SBIRT grant programs. Ninety patients who received BT and 878 who received BI. Per-patient cost of SBIRT, patient demographics and six measures of substance use: proportion using alcohol, proportion using alcohol to intoxication, days of alcohol use, days of alcohol use to intoxication, proportion using drugs and days using drugs. BI and BT were associated with better outcomes. The cost of SBIRT was significantly higher for BT patients ($75.54 versus 16.32, 95% confidence interval, P < 0.01). BT would be cost-effective if the decision-maker had a willingness to pay of $8.90 for a 1 percentage point reduction in the probability of using any alcohol. For the other five outcomes, BT was less effective and more costly, and BI would be a better use of resources. It might be cost-effective to offer brief treatment if the goal is to abstain from alcohol. However, the higher effectiveness of brief treatment for this outcome is associated with considerable uncertainty and, because both brief intervention and brief treatment improve all outcomes, brief treatment does not appear to be a good use of resources. © 2017 Society for the Study of Addiction.

Impulsivity is an important component of many forms of psychopathology. Though widely used as an index of this construct, the 30-item Barratt Impulsiveness Scale-11 (BIS-11) has demonstrated questionable psychometric properties in several research reports. An 8-item shortened version has recently been proposed, the Barratt Impulsiveness Scale-Brief (BIS-Brief) form, which was designed to overcome some of the limitations of the longer scale. In this report, we examine the internal structure and theoretically relevant external correlates of this new short form in large archival samples of individuals involved in the criminal justice system (prison inmates, substance abusers in mandatory treatment, and forensic inpatients). Confirmatory factor analysis of the BIS-Brief indicates adequate fit following a relatively minor modification. Correlations between the BIS-Brief and an array of criterion measures-other self-report scales, interview-based measures, and behavioral outcomes-are consistent with predictions and show relatively little or no decrement in predictive validity when compared with the 30-item BIS-11. Our results suggest that the BIS-Brief is a promising brief measure of impulsivity that evinces good psychometric properties across a range of offender samples. (c) 2015 APA, all rights reserved).

In the last 3 decades, research has shown consistent association with marriage and mortality and morbidity benefits. Despite the known emotional and physiological benefits of marriage, and the high rate of marriage failure, there are no well-defined screening tools to identify at-risk marriages in primary care settings. Patients presenting to a family medicine clinic were asked to complete a one-item screening question about the level of satisfaction with their marriage. Participants were also asked to fill out the Dyadic Adjustment Scale (DAS), a validated 32-item marital adjustment scale. A total of 159 of 208 (76%) respondents completed the survey. The average DAS score was 111 (SD=21.5), similar to the national average of 114 (SD=17.8). Using the DAS as the gold standard for marital satisfaction, we assessed the level of agreement between the one item screener and the longer DAS. A Pearson's Correlation Coefficient showed a correlation of 0.67. ROC curve showed sensitivity 86% and specificity 86% for the one item screener. Area under the curve was 0.89 (95% CI=0.83-0.93). In addition, analysis of variance showed that predictors of marital satisfaction included more dinners shared a week (compared 0--2, 3-6, 7 nights a week) and dates a month (0, 1--3, >3). Paired t test showed perceived health and living with spouse to be significant. The one-item screening question was shown to have good correlation to the gold standard, as well as acceptable sensitivity and specificity for identifying current dissatisfaction with marriage in a primary care setting. Further research is needed to determine if screening in a primary care setting, correlated with early intervention, can help improve satisfaction and avoid divorce.

2015-07-01

In the past years, increasing evidence showed that many childhood cancer survivors suffer from psychological distress long after treatment ended. However, psychosocial issues are often neglected during follow-up care. Including screening for psychological distress before follow-up appointments might help addressing the topic in survivors who need support. Our aim was to systematically review the available evidence on screening for psychological distress in childhood cancer survivors. We found eight studies that investigated different screening tools for their utility in detecting psychological distress in childhood cancer survivors. The Brief Symptom Inventory-18 with an adapted cutoff score for childhood cancer survivors, and the newly developed short form of the Beck Depression Index were both shown to be of a potential benefit as brief screening tools in follow-up care. We identified promising screening tools to be used to detect psychological distress in childhood cancer survivors. However, there is still a lack of studies addressing applicability and effectiveness when screening is routinely implemented into follow-up care. To improve quality of follow-up care, and identify and treat survivors with psychological distress, screening tools should now be implemented and their adequacy further tested in day-to-day clinic life.

Tools that allow cost-effective screening of the susceptibility of cell lines to operating conditions which may apply during full scale processing are central to the rapid development of robust processes for cell-based therapies. In this paper, an ultra scale-down (USD) device has been developed for the characterization of the response of a human cell line to membrane-based processing, using just a small quantity of cells that is often all that is available at the early discovery stage. The cell line used to develop the measurements was a clinically relevant human fibroblast cell line. The impact was evaluated by cell damage on completion of membrane processing as assessed by trypan blue exclusion and release of intracellular lactate dehydrogenase (LDH). Similar insight was gained from both methods and this allowed the extension of the use of the LDH measurements to examine cell damage as it occurs during processing by a combination of LDH appearance in the permeate and mass balancing of the overall operation. Transmission of LDH was investigated with time of operation and for the two disc speeds investigated (6,000 and 10,000 rpm or ϵ max  ≈ 1.9 and 13.5 W mL -1 , respectively). As expected, increased energy dissipation rate led to increased transmission as well as significant increases in rate and extent of cell damage. The method developed can be used to test the impact of varying operating conditions and cell lines on cell damage and morphological changes. Biotechnol.

Parkinson's disease (PD) is a movement disorder with significant neuropsychiatric comorbidities. Electroconvulsive therapy (ECT) is effective in treating these neuropsychiatric symptoms; however, clinicians are reluctant to use ECT in patients with deep brain stimulation (DBS) implantations for fear of damaging the device, as well as potential cognitive side effects. Right unilateral ultra-brief pulse (RUL UBP) ECT has a more favorable cognitive side-effect profile yet has never been reported in PD patients with DBS implants. We present a case series of three patients with a history of PD that all presented with psychiatric decompensation immediately prior to planned DBS surgery. All three patients had DBS electrode(s) in place at the time and an acute course of ECT was utilized in a novel method to "bridge" these individuals to neurosurgery. The patients all experienced symptom resolution (psychosis and/or depression and/or anxiety) without apparent cognitive side effects. This case series not only illustrates that right unilateral ultra-brief pulse can be utilized in patients with DBS electrodes but also illustrates that this intervention can be utilized as a neuromodulatory "bridge", where nonoperative surgical candidates with unstable psychiatric symptoms can be converted to operative candidates in a manner similar to electrical cardioversion.

Reaction of photochemical resists used in screen printing under the influence of digitally modulated ultra violet light

Different chemical photo-reactive emulsions are used in screen printing for stencil production. Depending on the bandwidth, optical power and depth of field from the optical system, the reaction / exposure speed has a diverse value. In this paper, the emulsions get categorized and validated in a first step. After that a mathematical model gets developed and adapted due to heuristic experience to estimate the exposure speed under the influence of digitally modulated ultra violet (UV) light. The main intention is to use the technical specifications (intended wavelength, exposure time, distance to the stencil, electrical power, stencil configuration) in the emulsion data sheet primary written down with an uncertainty factor for the end user operating with large projector arc lamps and photo films. These five parameters are the inputs for a mathematical formula which gives as an output the exposure speed for the Computer to Screen (CTS) machine calculated for each emulsion / stencil setup. The importance of this work relies in the possibility to rate with just a few boundaries the performance and capacity of an exposure system used in screen printing instead of processing a long test series for each emulsion / stencil configuration.

An exhaustive analysis of metabolites in hair samples has been performed for the first time using ultra performance liquid chromatography with electrospray ionization time-of-flight mass spectrometry (UPLC-ESI-TOF-MS). The hair samples were collected from spontaneously hypertensive model rats (SHR/Izm), stroke-prone SHR (SHRSP/Izm) and Wistar Kyoto (WKY/Izm) rats, and were analyzed by UPLC-ESI-TOF-MS; a multivariate statistical analysis method, such as the principal component analysis (PCA), was then used for screening the biomarkers. From the samples derived from the group of SHRSP/Izm at weeks 10, 18, 26 and 34, we successfully detected a potential biomarker of stroke, which existed at much higher concentrations as compared with that in the other groups. However, a significant difference could not be found at weeks less than 7 before the rats were subjected to stroke and hypertension. In addition, the present method was applicable to screening not only the disease markers, but also the markers related to aging. The method utilizing hair samples is expected to be quite useful for screening biomarkers of many other diseases, and not limited to stroke and hypertension.

Maternal mental health (particularly depression) may influence how they report on their child’s behavior. Few research studies have focused on Sub-Saharan countries where pediatric HIV concentrates and impacts child neuropsychological development and caregiver mental health. We investigated the associations between caregivers’ depressive symptoms and neuropsychological outcomes in HIV-infected (n=118) and HIV-exposed (n=164) Ugandan children aged 2–5 years. We compared performance-based tests of development (Mullen Scales of Early Learning, Color Object Association Test), to a caregiver report of executive function (Behavior Rating Inventory of Executive Function, BRIEF). Caregivers were assessed with Hopkins Symptom Checklist-25 depression subscale. The associations between all BRIEF indices and caregiver’s depression symptoms were differential according to child’s HIV status. Caregivers with greater depressive symptoms reported their HIV-infected children as having more behavioral problems related to executive functioning. Assessment of behavior of HIV-infected children should incorporate a variety of sources of information and screening of caregiver mental health. PMID:27175052

We examined the usefulness of brief neuropsychological tests and serum Aβ as a predictive test for detecting MCI/AD in older adults. Serum Aβ levels were measured from 208 subjects who were cognitively normal at enrollment and blood draw. Twenty-eight of the subjects subsequently developed MCI (n = 18) or AD (n = 10) over the follow-up period. Baseline measures of global cognition, memory, language fluency, and serum Aβ1–42 and the ratio of serum Aβ1–42/Aβ1–40 were significant predictors for future MCI/AD using Cox regression with demographic variables, APOE ε4, vascular risk factors, and specific medication as covariates. An optimal sensitivity of 85.2% and specificity of 86.5% for predicting MCI/AD was achieved using ROC analyses. Brief neuropsychological tests and measurements of Aβ1–42 obtained via blood warrants further study as a practical and cost effective method for wide-scale screening for identifying older adults who may be at-risk for pathological cognitive decline.

Aboriginal and Torres Strait Islander Community Controlled Health Services (ACCHSs) around Australia have been asked to standardise screening for unhealthy drinking. Accordingly, screening with the 3-item AUDIT-C (Alcohol Use Disorders Identification Test-Consumption) tool has become a national key performance indicator. Here we provide an overview of suitability of AUDIT-C and other brief alcohol screening tools for use in ACCHSs. All peer-reviewed literature providing original data on validity, acceptability or feasibility of alcohol screening tools among Indigenous Australians was reviewed. Narrative synthesis was used to identify themes and integrate results. Three screening tools-full AUDIT, AUDIT-3 (third question of AUDIT) and CAGE (Cut-down, Annoyed, Guilty and Eye-opener) have been validated against other consumption measures, and found to correspond well. Short forms of AUDIT have also been found to compare well with full AUDIT, and were preferred by primary care staff. Help was often required with converting consumption into standard drinks. Researchers commented that AUDIT and its short forms prompted reflection on drinking. Another tool, the Indigenous Risk Impact Screen (IRIS), jointly screens for alcohol, drug and mental health risk, but is relatively long (13 items). IRIS has been validated against dependence scales. AUDIT, IRIS and CAGE have a greater focus on dependence than on hazardous or harmful consumption. Detection of unhealthy drinking before harms occur is a goal of screening, so AUDIT-C offers advantages over tools like IRIS or CAGE which focus on dependence. AUDIT-C's brevity suits integration with general health screening. Further research is needed on facilitating implementation of systematic alcohol screening into Indigenous primary healthcare.

A significant regression model found depression, emotion-focused coping, and greater years since diagnosis as significant predictors of subjective caregiver burden. Thus, caregiving appears a dominant role for this group and the Brief Assessment Scale for Caregivers of the Medically Ill (BASC) appears to be an efficient screening tool for psychological morbidity in this under-supported group.

Studies have shown a lower adherence to health behaviors among women in cultural-ethnic minorities and faith-based communities, especially lower screening attendance for the early detection of breast cancer. This study compares factors related to cancer screening adherence in two distinct cultural-ethnic minorities in Israel: Arab women as a cultural-ethnic minority and Jewish ultra-Orthodox women as a cultural-ethnic faith-based minority. During the year 2014, a total of 398 Jewish ultra-Orthodox women and 401 Arab women between the ages of 40-60, were randomly selected using population-based registries. These women answered questionnaires regarding adherence to mammography and clinical breast examination (CBE), health beliefs and cultural barriers. Arab women adhered more than ultra-Orthodox women to mammography (p < .001) and CBE exams (p < .01). Religious beliefs, exposure barriers and perceived risk were higher among the ultra-Orthodox women, while social barriers, accessibility barriers and perceived severity were higher among the Arab women (p < .01). Adjusting for background factors, higher adherence to CBE and mammography were associated with lower levels of religious beliefs (AOR = 0.90, 95% CI = 0.69-1.17 AOR = 0.62, 95% CI = 0.39-0.82, respectively), perceiving a higher risk of cancer (AOR = 1.93, 95% CI = 1.23-3.04 and AOR = 3.22, 95% CI = 1.53-6.61), and having more fears related to cancer-related losses (AOR = 1.51, 95% CI = 1.19-3.00 and AOR = 1.24, 95% CI = 0.63-1.22). In addition, perceiving greater advantages of CBE was associated with higher adherence to CBE (AOR = 1.82, 95% CI = 1.45-2.29), while not receiving a physician's recommendation was associated with lower adherence to mammography (AOR = 1.82, 95% CI = 1.45-2.29). This study addressed a lacuna in screening behaviors of women from cultural-ethnic and faith-based communities. In order to increase adherence, health care professionals and policymakers should direct their attention to the specific nature of each community.

The flatness and parallelism error of large scale and ultra thin optics have an important influence on the subsequent polishing efficiency and accuracy. In order to realize the high precision grinding of those ductile elements, the low deformation vacuum chuck was designed first, which was used for clamping the optics with high supporting rigidity in the full aperture. Then the optics was planar grinded under vacuum adsorption. After machining, the vacuum system was turned off. The form error of optics was on-machine measured using displacement sensor after elastic restitution. The flatness would be convergenced with high accuracy by compensation machining, whose trajectories were integrated with the measurement result. For purpose of getting high parallelism, the optics was turned over and compensation grinded using the form error of vacuum chuck. Finally, the grinding experiment of large scale and ultra thin fused silica optics with aperture of 430mm×430mm×10mm was performed. The best P-V flatness of optics was below 3 μm, and parallelism was below 3 ″. This machining technique has applied in batch grinding of large scale and ultra thin optics.

Implementation of brief alcohol interventions by nurses in primary care: do non-clinical factors influence practice?

In the UK, GPs and practice nurses selectively provide brief alcohol interventions to risk drinkers. GPs' provision of a brief alcohol intervention can be predicted by patient characteristics, practitioner characteristics and structural factors such as the features of the practice and how it is organized. However, much less is known about possible modifiers of nurse practice. Our aim was to investigate if patient characteristics, nurse characteristics and practice factors influence provision of a brief alcohol intervention by practice nurses in primary health care. One hundred and twenty-eight practice nurses who had implemented a brief alcohol intervention programme in a previous trial based in the North of England were requested to screen adults presenting to their surgery and follow a structured protocol to give a brief intervention (5 min of advice plus an information booklet) to all 'risk' drinkers. Anonymized carbon copies of 5541 completed Alcohol Use Disorders Identification Test (AUDIT) screening questionnaires were collected after a 3-month implementation period and analysed by logistic regression analysis. Although AUDIT identified 1500 'risk' drinkers, only 926 (62%) received a brief intervention. Logistic regression modelling showed that patients' risk status as measured by AUDIT score was the most influential predictor of a brief intervention by practice nurses. However, risk drinkers who were most likely to receive a brief intervention were male. Patients' age or social class did not independently predict a brief intervention. The multilevel model was unable to identify any independent nurse characteristics that could predict a brief intervention, but indicated significant variation between nurses in their tendency to offer the intervention to patients. No structural factors were found to be positively associated with selective provision. Patient and nurse factors contributed to the selective provision of a brief intervention in primary care. If patients are to experience the beneficial effects of a brief alcohol intervention, then there is a need to improve the accuracy of delivery.

Development and validation of a brief trauma screening measure for children: The Child Trauma Screen.

PubMed

Lang, Jason M; Connell, Christian M

2017-05-01

Childhood exposure to trauma, including violence and abuse, is a major public health concern that has resulted in increased efforts to promote trauma-informed child-serving systems. Trauma screening is an important component of such trauma-informed systems, yet widespread use of trauma screening is rare in part due to the lack of brief, validated trauma screening measures for children. We describe development and validation of the Child Trauma Screen (CTS), a 10-item screening measure of trauma exposure and posttraumatic stress disorder (PTSD) symptoms for children consistent with the DSM-5 definition of PTSD. Study 1 describes measure development incorporating analysis to derive items based on existing measures from 1,065 children and caregivers together with stakeholder input to finalize item selection. Study 2 describes validation of the CTS with a clinical sample of 74 children and their caregivers. Results support the CTS as an empirically derived, reliable measure to screen children for trauma exposure and PTSD symptoms with strong convergent, divergent, and criterion validity. The CTS is a promising measure for rapidly and reliably screening children for trauma exposure and PTSD symptoms. Future research is needed to confirm validation and to examine feasibility and utility of its use across various child-serving systems. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Screening, brief intervention, and referral to treatment for opioid and other substance use during infertility treatment.

Wright, Tricia E

2017-08-01

Opioid use and misuse have reached epidemic proportions in the United States, especially in women of childbearing age, some of whom seek infertility treatments. Substance use is much more common than many of the conditions routinely screened for during the preconception period, and it can have devastating consequences for the woman and her family. Substance use can worsen infertility, complicate pregnancy, increase medical problems, and lead to psychosocial difficulties for the woman and her family. The reproductive endocrinologist thus has an ethical and medical duty to screen for substance use, provide initial counseling, and refer to specialized treatment as needed. This article provides an overview of screening, brief intervention, and referral to treatment (SBIRT), a public health approach shown to be effective in ameliorating the harms of substance use.

Recent progress and challenges in nanotechnology for biomedical applications: an insight into the analysis of neurotransmitters.

PubMed

Shankaran, Dhesingh Ravi; Miura, Norio

2007-01-01

Nanotechnology offers exciting opportunities and unprecedented compatibilities in manipulating chemical and biological materials at the atomic or molecular scale for the development of novel functional materials with enhanced capabilities. It plays a central role in the recent technological advances in biomedical technology, especially in the areas of disease diagnosis, drug design and drug delivery. In this review, we present the recent trend and challenges in the development of nanomaterials for biomedical applications with a special emphasis on the analysis of neurotransmitters. Neurotransmitters are the chemical messengers which transform information and signals all over the body. They play prime role in functioning of the central nervous system (CNS) and governs most of the metabolic functions including movement, pleasure, pain, mood, emotion, thinking, digestion, sleep, addiction, fear, anxiety and depression. Thus, development of high-performance and user-friendly analytical methods for ultra-sensitive detection of neurotransmitters remain a major challenge in modern biomedical analysis. Nanostructured materials are emerging as a powerful mean for diagnosis of CNS disorders because of their unique optical, size and surface characteristics. This review provides a brief outline on the basic concepts and recent advancements of nanotechnology for biomedical applications, especially in the analysis of neurotransmitters. A brief introduction to the nanomaterials, bionanotechnology and neurotransmitters is also included along with discussions on most of the patents published in these areas.

The study of the neuropsychological profile of schizophrenic patients has provided systematic results in linking specific deficit (working memory, verbal learning, attentive and executive functioning, social cognition) to the functional outcome of subjects. More recently this approach has been applied to younger subjects, from the age of 14, that show prodromal signs of a possible psychotic conversion (ultra-risk subjects). The review is at first intended to describe the clinical and experimental studies that investigated the cognitive and neuropsychological profile of subjects at ultra-risk for psychosis. These studies show the presence of minor cognitive difficulties in several specific areas (working memory, verbal learning, attentive and executive functioning) that can be indicative of both a possible conversion to psychosis and a need for cognitive remediation programs. Secondarily, the article describes several neuropsychological tools, standardized for the Italian population, that can be used to approach the clinical assessment of ultra-risk subjects considering some critical aspects such as their typical age range (adolescents and young adults).

Aims: Large-scale epidemiological studies show a significant prevalence of gambling disorder (GD) during adolescence and emerging adulthood, and highlight the need to identify gambling-related behaviors at early ages. However, there are only a handful of screening instruments for this population and many studies measuring youth gambling problems use adult instruments that may not be developmentally appropriate. The aim of this study was to validate a Spanish version of the Canadian Adolescent Gambling Inventory (CAGI) among late adolescent and young adults and to explore its psychometric properties. Methods: The sample (16-29 years old) included a clinical group ( n = 55) with GD patients and a control group ( n = 340). Results: Exploratory factor analysis yielded one factor as the best model. This 24-item scale demonstrated satisfactory reliability (internal consistency, Cronbach's alpha, α = 0.91), satisfactory convergent validity as measured by correlation with South Oaks Gambling Screen ( r = 0.74), and excellent classification accuracy (AUC = 0.99; sensitivity = 0.98; and specificity = 0.99). Conclusion: Our results provide empirical support for our validation of the Spanish version of the CAGI. We uphold that the Spanish CAGI can be used as a brief, reliable, and valid instrument to assess gambling problems in Spanish youth.

Developments in the Implementation of Acoustic Droplet Ejection for Protein Crystallography.

Acoustic droplet ejection (ADE) enables crystallization experiments at the low-nanoliter scale, resulting in rapid vapor diffusion equilibration dynamics and efficient reagent usage in the empirical discovery of structure-enabling protein crystallization conditions. We extend our validation of this technology applied to the diverse physicochemical property space of aqueous crystallization reagents where dynamic fluid analysis coupled to ADE aids in accurate and precise dispensations. Addition of crystallization seed stocks, chemical additives, or small-molecule ligands effectively modulates crystallization, and we here provide examples in optimization of crystal morphology and diffraction quality by the acoustic delivery of ultra-small volumes of these cofactors. Additional applications are discussed, including set up of in situ proteolysis and alternate geometries of crystallization that leverage the small scale afforded by acoustic delivery. Finally, we describe parameters of a system of automation in which the acoustic liquid handler is integrated with a robotic arm, plate centrifuge, peeler, sealer, and stacks, which allows unattended high-throughput crystallization experimentation. © 2015 Society for Laboratory Automation and Screening.

Brief screening questionnaires to identify problem drinking during pregnancy: a systematic review.

2010-04-01

Although prenatal screening for problem drinking during pregnancy has been recommended, guidance on screening instruments is lacking. We investigated the sensitivity, specificity and predictive value of brief alcohol screening questionnaires to identify problem drinking in pregnant women. Electronic databases from their inception to June 2008 were searched, as well as reference lists of eligible papers and related review papers. We sought cohort or cross-sectional studies that compared one or more brief alcohol screening questionnaire(s) with reference criteria obtained using structured interviews to detect 'at-risk' drinking, alcohol abuse or dependency in pregnant women receiving prenatal care. Five studies (6724 participants) were included. In total, seven instruments were evaluated: TWEAK (Tolerance, Worried, Eye-opener, Amnesia, Kut down), T-ACE [Take (number of drinks), Annoyed, Cut down, Eye-opener], CAGE (Cut down, Annoyed, Guilt, Eye-opener], NET (Normal drinker, Eye-opener, Tolerance), AUDIT (Alcohol Use Disorder Identification Test), AUDIT-C (AUDIT-consumption) and SMAST (Short Michigan Alcohol Screening Test). Study quality was generally good, but lack of blinding was a common weakness. For risk drinking sensitivity was highest for T-ACE (69-88%), TWEAK (71-91%) and AUDIT-C (95%), with high specificity (71-89%, 73-83% and 85%, respectively). CAGE and SMAST performed poorly. Sensitivity of AUDIT-C at score >or=3 was high for past year alcohol dependence (100%) or alcohol use disorder (96%) with moderate specificity (71% each). For life-time alcohol dependency the AUDIT at score >or=8 performed poorly. T-ACE, TWEAK and AUDIT-C show promise for screening for risk drinking, and AUDIT-C may also be useful for identifying alcohol dependency or abuse. However, their performance as stand-alone tools is uncertain, and further evaluation of questionnaires for prenatal alcohol use is warranted.

To examine diagnostic accuracy of anxiety detection tools compared with a gold standard in outpatient settings among adults with Parkinson disease (PD). A systematic review was conducted. MEDLINE, EMABASE, PsycINFO, and Cochrane Database of Systematic Reviews were searched to April 7, 2017. Prevalence of anxiety and diagnostic accuracy measures including sensitivity, specificity, and likelihood ratios were gathered. Pooled prevalence of anxiety was calculated using Mantel-Haenszel-weighted DerSimonian and Laird models. A total of 6,300 citations were reviewed with 6 full-text articles included for synthesis. Tools included within this study were the Beck Anxiety Inventory, Geriatric Anxiety Inventory (GAI), Hamilton Anxiety Rating Scale, Hospital Anxiety and Depression Scale-Anxiety, Parkinson's Anxiety Scale (PAS), and Mini-Social Phobia Inventory. Anxiety diagnoses made included generalized anxiety disorder, social phobia, and any anxiety type. Pooled prevalence of anxiety was 30.1% (95% confidence interval 26.1%-34.0%). The GAI had the best-reported sensitivity of 0.86 and specificity of 0.88. The observer-rated PAS had a sensitivity of 0.71 and the highest specificity of 0.91. While there are 6 tools validated for anxiety screening in PD populations, most tools are only validated in single studies. The GAI is brief and easy to use, with a good balance of sensitivity and specificity. The PAS was specifically developed for PD, is brief, and has self-/observer-rated scales, but with lower sensitivity. Health care practitioners involved in PD care need to be aware of available validated tools and choose one that fits their practice. Copyright © 2017 American Academy of Neurology.

The design organization test: further demonstration of reliability and validity as a brief measure of visuospatial ability.

Neuropsychological assessments are frequently time-consuming and fatiguing for patients. Brief screening evaluations may reduce test duration and allow more efficient use of time by permitting greater attention toward neuropsychological domains showing probable deficits. The Design Organization Test (DOT) was initially developed as a 2-min paper-and-pencil alternative for the Block Design (BD) subtest of the Wechsler scales. Although initially validated for clinical neurologic patients, we sought to further establish the reliability and validity of this test in a healthy, more diverse population. Two alternate versions of the DOT and the Wechsler Abbreviated Scale of Intelligence (WASI) were administered to 61 healthy adult participants. The DOT showed high alternate forms reliability (r = .90-.92), and the two versions yielded equivalent levels of performance. The DOT was highly correlated with BD (r = .76-.79) and was significantly correlated with all subscales of the WASI. The DOT proved useful when used in lieu of BD in the calculation of WASI IQ scores. Findings support the reliability and validity of the DOT as a measure of visuospatial ability and suggest its potential worth as an efficient estimate of intellectual functioning in situations where lengthier tests may be inappropriate or unfeasible.

Age-Neutrality of a Brief Assessment of the Section III Alternative Model for Personality Disorders in Older Adults.

The alternative model for personality disorders in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders ( DSM-5) is considered an important step toward a possibly better conceptualization of personality pathology in older adulthood, by the introduction of levels of personality functioning (Criterion A) and trait dimensions (Criterion B). Our main aim was to examine age-neutrality of the Short Form of the Severity Indices of Personality Problems (SIPP-SF; Criterion A) and Personality Inventory for DSM-5-Brief Form (PID-5-BF; Criterion B). Differential item functioning (DIF) analyses and more specifically the impact on scale level through differential test functioning (DTF) analyses made clear that the SIPP-SF was more age-neutral (6% DIF, only one of four domains showed DTF) than the PID-5-BF (25% DIF, all four tested domains had DTF) in a community sample of older and younger adults. Age differences in convergent validity also point in the direction of differences in underlying constructs. Concurrent and criterion validity in geriatric psychiatry inpatients suggest that both the SIPP-SF scales measuring levels of personality functioning (especially self-functioning) and the PID-5-BF might be useful screening measures in older adults despite age-neutrality not being confirmed.

To estimate changes in the substance use behaviors of patients who received services as part of the US Substance Abuse and Mental Health Services Administration's (SAMHSA) Screening, Brief Intervention and Referral to Treatment (SBIRT) grant program. We use a pre-post design and performance monitoring data collected by SBIRT organizations. For a sample of 17 575 patients, we compare pre-SBIRT substance use with substance use 6 months after receipt of SBIRT services. SBIRT's correlation with changes in substance use was estimated using generalized linear mixed models to account for the clustering of patients within health-care facility and US state. From pre- to post-SBIRT we found large and statistically significant decreases for almost every measure of substance use. Model-adjusted means indicate that the prevalence of alcohol use was lower 6 months later by 35.6%, heavy drinking by 43.4% and illicit drug use by 75.8%. Greater intervention intensity was associated with larger decreases in substance use. The study design does not support causal conclusions and estimated decreases in reported substance use are due, at least in part, to a well-known set of confounders and natural substance use patterns that may be unrelated to any particular SBIRT intervention. Compared with previously published findings on the Screening, Brief Intervention and Referral to Treatment grant program, our estimates of substance use reduction were smaller, but still consistently large in absolute magnitude and within ranges of estimates from past trials of Screening, Brief Intervention and Referral to Treatment. © 2017 Society for the Study of Addiction.

Excessive drinking is responsible for one in ten deaths among working-age adults in the U.S. annually. Alcohol screening and brief intervention is an effective but underutilized intervention for reducing excessive drinking among adults. Electronic screening and brief intervention (e-SBI) uses electronic devices to deliver key elements of alcohol screening and brief intervention, with the potential to expand population reach. Using Community Guide methods, a systematic review of the scientific literature on the effectiveness of e-SBI for reducing excessive alcohol consumption and related harms was conducted. The search covered studies published from 1967 to October 2011. A total of 31 studies with 36 study arms met quality criteria and were included in the review. Analyses were conducted in 2012. Twenty-four studies (28 study arms) provided results for excessive drinkers only and seven studies (eight study arms) reported results for all drinkers. Nearly all studies found that e-SBI reduced excessive alcohol consumption and related harms: nine study arms reported a median 23.9% reduction in binge-drinking intensity (maximum drinks/binge episode) and nine study arms reported a median 16.5% reduction in binge-drinking frequency. Reductions in drinking measures were sustained for up to 12 months. According to Community Guide rules of evidence, e-SBI is an effective method for reducing excessive alcohol consumption and related harms among intervention participants. Implementation of e-SBI could complement population-level strategies previously recommended by the Community Preventive Services Task Force for reducing excessive drinking (e.g., increasing alcohol taxes and regulating alcohol outlet density).

Objective: A randomized, controlled trial of screening, brief intervention, and referral to treatment (SBIRT) for drinking and related problems among at-risk and dependent drinkers was conducted in an emergency department (ED) in Sosnowiec, Poland, among patients ages 18 years and older. Method: Data were collected over a 23-week period, from 4:00 pm to midnight, and resulted in 446 patients being recruited into the study (90% of those who screened positive) and randomized to three conditions following a two-stage process: screened only (n = 147), assessed (n = 152), and received intervention (n = 147). Patients in the assessment (85%) and intervention (83%) conditions were blindly reassessed at 3 months via a telephone interview. Results: At 3-month follow-up, both groups showed significant decreases in the proportion who were positive for at-risk drinking, the primary outcome variable. Both groups also showed significant decreases in drinking days per week, drinks per drinking day, maximum drinks per occasion, and negative consequences of drinking. Using analysis of covariance to control for baseline measures and demographic characteristics, no difference in outcome measures was found between intervention and assessment conditions. Subgroup analysis found some significant interactions between intervention and secondary outcomes. Conclusions: Although the main findings were similar to those from other brief-intervention studies in Western cultures, findings here also suggest that intervention may have differential benefits for specific subgroups of patients in the ED, an area of research that may warrant additional study of brief intervention in the ED setting.

Many persons who drink excessively remain unidentified and do not receive interventions. Screening and intervention using the World Wide Web could make such services more accessible and therefore more widely used. To evaluate the use of a novel alcohol screening and brief intervention Web site. A Web site was developed, posted, and its use was evaluated. We analyzed a sample of visitors who completed alcohol screening over a 14-month period to describe their alcohol use, and their use of portions of the Web site that provide information and referral resources. The Internet. Web site visitors, with a focus on visitors who completed an alcohol-screening questionnaire about their own drinking. Brief intervention via the Web site, consisting mainly of feedback, advice, and a menu of change options and referral information. Self-reported drinking amounts and alcohol screening test scores, and utilization of Web site components. Visitors completed online alcohol screening questionnaires at a rate of 50,711/year of 115,925 visitors/year. In a 14-month period, 39,842 adults completed the questionnaire about their own drinking habits; 66% were men, 90% reported drinking hazardous amounts (per occasion or typical weekly amounts), 88% reported binge (per occasion) drinking, and 55% reported typically exceeding weekly risky drinking limits. Most (65%) had alcohol screening test results (AUDIT > or = 8) consistent with alcohol abuse or dependence; similar proportions of women and men were hazardous drinkers. One-fifth of visitors visited portions of the Web site that provided additional information about alcohol use and referrals. Visitors with possible alcohol abuse or dependence were more likely than those without these disorders to visit a part of the Web site designed for those seeking additional help (33% vs. 8%, P < 0.0001). A well-publicized, easily accessible, research-based screening and intervention Web site can attract many users, most of whom are drinking excessively, and many of whom avail themselves of referral information after receiving individualized feedback.

To assess the structural overlap between the Behavior Rating Inventory of Executive Function (BRIEF) and Achenbach Child Behavior Checklist (CBCL) among children in Uganda. Caregiver ratings for the BRIEF and CBCL were obtained for 2 independent samples of school-aged children: 106 children (5-12 years old, 50% males) with a history of severe malaria and on 144 HIV-infected children (5-12 years old, 58% males) in Uganda. Exploratory factor analysis was used to evaluate the factor structure of the 8 subscales for the BRIEF and the 8 scales of the CBCL to determine correlation. Overall, children in the severe malaria group had higher (increased symptom) BRIEF and CBCL scores than those in the HIV-infected group. Three factors that provided a reasonable fit to the data and could be characterized as 3 specific domains were identified: (1) Metacognition, which consisted of the scales in the BRIEF Metacognition domain, (2) Behavioral Adjustment, which comprised of the scales in the BRIEF Behavioral Regulation domain and the Externalizing Symptoms scales in the CBCL, and (3) Emotional Adjustment, which mainly consisted of the Internalizing Symptoms scales in the CBCL. The BRIEF Behavior Regulation and CBCL Externalizing Symptoms scales, however, did overlap in terms of assessing similar behavior symptoms. These findings were consistent across the severe malaria and HIV-infected samples of children. The BRIEF and CBCL instruments offer distinct, yet complementary, assessments of behavior in clinical pediatric populations in the Ugandan context, supporting the use of these measures for similar research settings.

Adolescent firearms-carrying is a risk factor for serious injury and death. Clinical screening tools for firearms-carrying have not yet been developed. We present the development of a preliminary screening test for adolescent firearms-carrying based on the growing body of knowledge of firearms-related risk factors. A convenience sample of 15,000 high school students from the 1999 National Youth Risk Behavior Survey was analyzed for the purpose of model building. Known risk factors for firearms-carrying were candidates for 2 models predicting recent firearms-carrying. The "brief FiGHTS score" screening tool excluded terms related to sexual behavior, significant substance abuse, or criminal behavior (Fi=fighting, G=gender, H=hurt while fighting, T=threatened, S=smoker). An "extended FiGHTS score," which included 13 items, was developed for more precise estimates. The brief FiGHTS score had a sensitivity of 82%, a specificity of 71%, and an area under the receiver operating characteristic (ROC) curve of 0.84. The extended FiGHTS score had an area under the ROC curve of 0.90. Both models performed well in a validation data set of 55,000 students. The brief and extended FiGHTS scores have high sensitivity and specificity for predicting firearms-carrying and may be appropriate for clinical testing.

Overconsumption of alcohol is well known to lead to numerous health and social problems. Prevalence studies of United States adults found that 20% of patients meet criteria for an alcohol use disorder. Routine screening for alcohol use is recommended in primary care settings, yet little is known about the organizational factors that are related to successful implementation of screening and brief intervention (SBI) and treatment in these settings. The purpose of this study was to evaluate organizational attributes in primary care practices that were included in a practice-based research network trial to implement alcohol SBI. The Survey of Organizational Attributes in Primary Care (SOAPC) has reliably measured four factors: communication, decision-making, stress/chaos and history of change. This 21-item instrument was administered to 178 practice members at the baseline of this trial, to evaluate for relationship of organizational attributes to the implementation of alcohol SBI and treatment. No significant relationships were found correlating alcohol screening, identification of high-risk drinkers and brief intervention, to the factors measured in the SOAPC instrument. These results highlight the challenges related to the use of organizational survey instruments in explaining or predicting variations in clinical improvement. Comprehensive mixed methods approaches may be more effective in evaluations of the implementation of SBI and treatment. Copyright © 2013 Elsevier Ltd. All rights reserved.

This study describes a novel Miniaturized INtrinsic DISsolution Screening (MINDISS) assay for measuring disk intrinsic dissolution rates (DIDR). In MINDISS, compacted mini disks of drugs (2-5mg/disk) are prepared in custom made holders with a surface area of 3mm(2). Disks are immersed, pellet side down, into 0.35ml of appropriate dissolution media per well in 96-well microtiter plates, media are stirred and disk-holders are transferred to new wells after defined periods of time. After filtration, drug concentration in dissolution media is quantified by Ultra Performance Liquid Chromatography (UPLC) and solid state property of the disk is characterized by Raman spectroscopy. MINDISS was identified as an easy-to-use tool for rapid, parallel determination of DIDR of compounds that requires only small amounts of compound and of dissolution medium. Results obtained with marketed drugs in MINDISS correlate well with large scale DIDR methods and indicate that MINDISS can be used for (1) rank-ordering of compounds by intrinsic dissolution in late phase discovery and early development, (2) comparison of polymorphic forms and salts, (3) screening and selection of appropriate dissolution media, and (4) characterization of the intestinal release behavior of compounds along the gastro intestinal tract by changing biorelevant media during experiments.

To evaluate the Symbol Digit Modalities Test (SDMT) as a tool for identifying pediatric-onset MS patients at risk for cognitive impairment. The SDMT is a brief measure of cognitive processing speed that is often used in adult MS patients. Approximately one-third of pediatric-onset MS patients have cognitive impairment and there is a need for an effective screening instrument. Seventy (70) consecutive outpatients with pediatric-onset MS underwent clinical evaluations including the SDMT and were compared to those with other pediatric neurological diagnoses (OND, n=40) and healthy controls (HC, n=32). A subset of the MS group and all healthy controls completed neuropsychological evaluation within one year of SDMT administration. The MS group performed worse on the SDMT compared to the HC group (p=0.02). Thirty-seven percent (37%) of the MS, 20% of the OND, and 9% of HC groups scored in the impaired range. For MS participants who underwent neuropsychological testing (n=31), the SDMT showed 77% sensitivity and 81% specificity for detecting neuropsychological impairment when administered within one year and reached 100% sensitivity when the interval was under two months (n=17). Overall, older age and increased disability predicted poorer SDMT performance (age r=-0.26, p=0.03) and the Expanded Disability Status Scale score or EDSS (r=-0.47, p<0.001), while a history of optic neuritis predicted better performance (p=0.04). Optical coherence tomography measures were not related to SDMT performance. In this preliminary study, the SDMT was an effective brief screen for detecting cognitive impairment in pediatric-onset MS.

Low background rare event searches in underground laboratories seeking observation of direct dark matter interactions or neutrino-less double beta decay have the potential to profoundly advance our understanding of the physical universe. Successful results from these experiments depend critically on construction from extremely radiologically clean materials and accurate knowledge of subsequent low levels of expected background. The experiments must conduct comprehensive screening campaigns to reduce radioactivity from detector components, and these measurements also inform detailed characterisation and quantification of background sources and their impact, necessary to assign statistical significance to any potential discovery. To provide requisite sensitivity for material screening and characterisation in the UK to support our rare event search activities, we have re-developed our infrastructure to add ultra-low background capability across a range of complementary techniques that collectively allow complete radioactivity measurements. Ultra-low background HPGe and BEGe detectors have been installed at the Boulby Underground Laboratory, itself undergoing substantial facility re-furbishment, to provide high sensitivity gamma spectroscopy in particular for measuring the uranium and thorium decay series products. Dedicated low-activity mass spectrometry instrumentation has been developed at UCL for part per trillion level contaminant identification to complement underground screening with direct U and Th measurements, and meet throughput demands. Finally, radon emanation screening at UCL measures radon background inaccessible to gamma or mass spectrometry techniques. With this new capability the UK is delivering half of the radioactivity screening for the LZ dark matter search experiment.

Validated clinician outcome scores are considered less associated with psychosocial factors than patient-reported outcome measurements (PROMs). This belief may lead to misconceptions if both instruments are related to similar factors. We asked: In patients with chronic shoulder pain, what biopsychosocial factors are associated (1) with PROMs, and (2) with clinician-rated outcome measurements? All new patients between the ages of 18 and 65 with chronic shoulder pain from a unilateral shoulder injury admitted to a Swiss rehabilitation teaching hospital between May 2012 and January 2015 were screened for potential contributing biopsychosocial factors. During the study period, 314 patients were screened, and after applying prespecified criteria, 158 patients were evaluated. The median symptom duration was 9 months (interquartile range, 5.5-15 months), and 72% of the patients (114 patients) had rotator cuff tears, most of which were work injuries (59%, 93 patients) and were followed for a mean of 31.6 days (SD, 7.5 days). Exclusion criteria were concomitant injuries in another location, major or minor upper limb neuropathy, and inability to understand the validated available versions of PROMs. The PROMs were the DASH, the Brief Pain Inventory, and the Patient Global Impression of Change, before and after treatment (physiotherapy, cognitive therapy and vocational training). The Constant-Murley score was used as a clinician-rated outcome measurement. Statistical models were used to estimate associations between biopsychosocial factors and outcomes. Greater disability on the DASH was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale combined coefficient, 0.64; 95% CI, 0.25-1.03; p = 0.002) and social factors (language, professional qualification combined coefficient, -6.15; 95% CI, -11.09 to -1.22; p = 0.015). Greater pain on the Brief Pain Inventory was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale combined coefficient, 0.076; 95% CI, 0.021-0.13; p = 0.006). Poorer impression of change was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia coefficient, 0.93; 95% CI, 0.87-0.99; p = 0.026) and social factors (education, language, and professional qualification coefficient, 6.67; 95% CI, 2.77-16.10; p < 0.001). Worse clinician-rated outcome was associated only with psychological factors (Hospital Anxiety and Depression Scale (depression only), Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia combined coefficient, -0.35; 95% CI, -0.58 to -0.12; p = 0.003). Depressive symptoms and catastrophizing appear to be key factors influencing PROMs and clinician-rated outcomes. This study suggests revisiting the Constant-Murley score.

Recent advances in liquid-phase separations for clinical metabolomics.

PubMed

Kohler, Isabelle; Giera, Martin

2017-01-01

Over the last decades, several technological improvements have been achieved in liquid-based separation techniques, notably, with the advent of fully porous sub-2 μm particles and superficially porous sub-3 μm particles, the comeback of supercritical fluid chromatography, and the development of alternative chromatographic modes such as hydrophilic interaction chromatography. Combined with mass spectrometry, these techniques have demonstrated their added value, substantially increasing separation efficiency, selectivity, and speed of analysis. These benefits are essential in modern clinical metabolomics typically involving the study of large-scale sample cohorts and the analysis of thousands of metabolites showing extensive differences in physicochemical properties. This review presents a brief overview of the recent developments in liquid-phase separation sciences in the context of clinical metabolomics, focusing on increased throughput as well as metabolite coverage. Relevant metabolomics applications highlighting the benefits of ultra-high performance liquid chromatography, core-shell technology, high-temperature liquid chromatography, capillary electrophoresis, supercritical fluid chromatography, and hydrophilic interaction chromatography are discussed. © 2016 WILEY-VCH Verlag GmbH & Co.

Introduction Alcohol misuse is a significant public health problem with major health, social and economic consequences. Systematic reviews have reported that brief advice interventions delivered in various health service settings can reduce harmful drinking. Although the links between alcohol and oral health are well established and dentists come into contact with large numbers of otherwise healthy patients regularly, no studies have been conducted in the UK to test the feasibility of delivering brief advice about alcohol in general dental settings. Methods and analysis The Dental Alcohol Reduction Trial (DART) aims to assess the feasibility and acceptability of screening for alcohol misuse and delivering brief advice in patients attending National Health Service (NHS) general dental practices in North London. DART is a cluster randomised control feasibility trial and uses a mixed methods approach throughout the development, design, delivery and evaluation of the intervention. It will be conducted in 12 NHS general dental practices across North London and will include dental patients who drink above the recommended guidance, as measured by the Alcohol Use Disorders Identification Test (AUDIT-C) screening tool. The intervention involves 5 min of tailored brief advice delivered by dental practitioners during the patient's appointment. Feasibility and acceptability measures as well as suitability of proposed primary outcomes of alcohol consumption will be assessed. Initial economic evaluation will be undertaken. Recruitment and retention rates as well as acceptability of the study procedures from screening to follow-up will be measured. Ethics and dissemination Ethical approval was obtained from the Camden and Islington Research Ethics Committee. Study outputs will be disseminated via scientific publications, newsletters, reports and conference presentations to a range of professional and patient groups and stakeholders. Based on the results of the trial, recommendations will be made on the conduct of a definitive randomised controlled trial. Trial registration number ISRCTN81193263. PMID:26443659

Background Alcohol misuse is common in people attending emergency departments (EDs) and there is some evidence of efficacy of alcohol screening and brief interventions (SBI). This study investigated the effectiveness of SBI approaches of different intensities delivered by ED staff in nine typical EDs in England: the SIPS ED trial. Methods and Findings Pragmatic multicentre cluster randomized controlled trial of SBI for hazardous and harmful drinkers presenting to ED. Nine EDs were randomized to three conditions: a patient information leaflet (PIL), 5 minutes of brief advice (BA), and referral to an alcohol health worker who provided 20 minutes of brief lifestyle counseling (BLC). The primary outcome measure was the Alcohol Use Disorders Identification Test (AUDIT) status at 6 months. Of 5899 patients aged 18 or more presenting to EDs, 3737 (63·3%) were eligible to participate and 1497 (40·1%) screened positive for hazardous or harmful drinking, of whom 1204 (80·4%) gave consent to participate in the trial. Follow up rates were 72% (n = 863) at six, and 67% (n = 810) at 12 months. There was no evidence of any differences between intervention conditions for AUDIT status or any other outcome measures at months 6 or 12 in an intention to treat analysis. At month 6, compared to the PIL group, the odds ratio of being AUDIT negative for brief advice was 1·103 (95% CI 0·328 to 3·715). The odds ratio comparing BLC to PIL was 1·247 (95% CI 0·315 to 4·939). A per protocol analysis confirmed these findings. Conclusions SBI is difficult to implement in typical EDs. The results do not support widespread implementation of alcohol SBI in ED beyond screening followed by simple clinical feedback and alcohol information, which is likely to be easier and less expensive to implement than more complex interventions.

Anderson, Jaime L; Sellbom, Martin; Salekin, Randall T

2018-07-01

The Diagnostic and Statistical Manual of Mental Disorders-Fifth edition ( DSM-5) Personality and Personality Disorders workgroup developed the Personality Inventory for the DSM-5 (PID-5) for the assessment of the alternative trait model for DSM-5. Along with this measure, the American Psychiatric Association published an abbreviated version, the PID-5-Brief form (PID-5-BF). Although this measure is available on the DSM-5 website for use, only two studies have evaluated its psychometric properties and validity and no studies have examined the U.S. version of this measure. The current study evaluated the reliability, factor structure, and construct validity of PID-5-BF scale scores. This included an evaluation of the scales' associations with Section II PDs, a well-validated dimensional measure of personality psychopathology, and broad externalizing and internalizing psychopathology measures. We found support for the reliability of PID-5-BF scales as well as for the factor structure of the measure. Furthermore, a series of correlation and regression analyses showed conceptually expected associations between PID-5-BF and external criterion variables. Finally, we compared the correlations with external criterion measures to those of the full-length PID-5 and PID-5-Short form. Intraclass correlation analyses revealed a comparable pattern of correlations across all three measures, thereby supporting the use of the PID-5-BF as a screening measure of dimensional maladaptive personality traits.

Targeted hepatitis C virus (HCV) screening is recommended. Implementation of screening in emergency department (ED) settings is challenging and controversial. Understanding HCV epidemiology in EDs could motivate and guide screening efforts. We characterized the prevalence of diagnosed and undiagnosed HCV in a Midwestern, urban ED. This was a cross-sectional seroprevalence study using de-identified blood samples and self-reported health information obtained from consecutively approached ED patients aged 18-64 years. Subjects consented to a "study of diseases of public health importance" and were compensated for participation. The Biochain ELISA kit for Human Hepatitis C Virus was used for antibody assay. Viral RNA was isolated using the Qiagen QIAamp UltraSens Virus kit, followed by real-time reverse transcription polymerase chain reaction using a Bio-Rad CFX96 SYBR Green UltraFast program with melt-curve analysis. HCV antibody was detected in 128 of 924 (14%; 95% confidence interval [CI], 12%-16%) samples. Of these, 44 (34%) self-reported a history of HCV or hepatitis of unknown type and 103 (81%; 95% CI, 73%-87%) were RNA positive. Two additional patients were antibody negative but RNA positive. Fully implemented birth cohort screening for HCV antibody would have missed 36 of 128 (28%) of cases with detectable antibody and 26 of 105 (25%) of those with replicative HCV infection. HCV infection is highly prevalent in EDs. Emergency departments are likely to be uniquely important for HCV screening, and logistical challenges to ED screening should be overcome. Birth cohort screening would have missed many patients, suggesting the need for complementary screening strategies applied to an expanded age range. © The Author 2016.

Anxiety experienced by women during their participation in breast cancer screening programs can condition their adherence to the program. The aim was to determine whether a brief nursing intervention could reduce anxiety before screening mammography. A randomized controlled trial carried out with 436 Spanish women aged between 50-69 years, who attended a population breast cancer screening program. The experimental group received an ad-hoc tailored intervention, which consisted of offering information about the screening program and the mammography exam, as well as of providing personal emotional support. Anxiety was assessed using the State-Trait Anxiety Inventory (STAI). Fear of screening outcome and fear of breast cancer were also assessed. Women of the experimental group had 60% less probability of having a high anxiety state (OR = 0.40; 95%: CI [0.25, 0.65]), after adjusting for sociodemographic and clinical variables. Regarding trait anxiety, no differences were observed between groups. The stratified analysis showed that this positive impact was greater in women who did not fear the screening outcome (OR = 0.24; 95% CI [0.11, 0.52]) or breast cancer (OR = 0.07; 95% CI [0.01, 0.41]). A protocolized nursing intervention reduced the probability of being anxious when undergoing a screening mammography.

The current study identified psychosocial variables associated with AUDIT-C hazardous drinking risk status for male and female college students. Logistic regression analysis revealed that AUDIT-C risk status was associated with alcohol-related negative consequences, injunctive norms, and descriptive norms for both male and female participants. Sociability and self-perception outcome expectancies predicted risk status for females. Cognitive and behavioral impairment expectancies predicted risk status for men in the sample. Implications for screening and brief intervention programming efforts are discussed. © The Author(s) 2015.

Material screening for identifying low-energy electron emitters and alpha-decaying isotopes is now a prerequisite for rare-event searches (e.g., dark-matter direct detection and neutrinoless double-beta decay) for which surface radiocon-tamination has become an increasingly important background. The BetaCage, a gaseous neon time-projection chamber, is a proposed ultra-sensitive (and nondestructive) screener for alpha-and beta-emitting surface contaminants to which existing screening facilities are insufficiently sensitive. Sensitivity goals are 0.1 betas keV-1 m-2 day-1 and 0.1 alphas m-2 day-1, with the former limited by Compton scattering of photons in the screening samples and (thanks to tracking) the latter expected to be signal-limited; radioassays and simulations indicate backgrounds from detector materials and radon daughters should be subdominant. We report on details of the background simulations and detector design that provide the discrimination, shielding, and radiopurity necessary to reach our sensitivity goals for a chamber with a 95 × 95 cm2 sample area positioned below a 40 cm drift region and monitored by crisscrossed anode and cathode planes consisting of 151 wires each.

Purpose Randomised controlled trials conducted in resource-limited settings have shown that once women with depressed mood are evaluated by specialists and referred for treatment, lay health workers can be trained to effectively administer psychological treatments. We sought to determine the extent to which community health workers could also be trained to conduct case finding using short and ultra-short screening instruments programmed into mobile phones. Methods Pregnant, Xhosa-speaking women were recruited independently in two cross-sectional studies (N=1,144 and N=361) conducted in Khayelitsha, South Africa and assessed for antenatal depression. In the smaller study, community health workers with no training in human subjects research were trained to administer the Edinburgh Postnatal Depression Scale (EPDS) during the routine course of their community-based outreach. We compared the operating characteristics of 4 short and ultra-short versions of the EPDS with the criterion standard of probable depression, defined as an EPDS-10 ≥13. Results The prevalence of probable depression (475/1144 [42%] and 165/361 [46%]) was consistent across both samples. The 2-item subscale demonstrated poor internal consistency (Cronbach’s α ranged from 0.55-0.58). All 4 subscales demonstrated excellent discrimination, with area under the receiver operating characteristic curve (AUC) values ranging from 0.91-0.99. Maximal discrimination was observed for the 7-item depressive symptoms subscale: at the conventional screening threshold of ≥10, it had 0.97 sensitivity and 0.76 specificity for detecting probable antenatal depression. Conclusions The comparability of the findings across the two studies suggests that it is feasible to use community health workers to conduct case finding for antenatal depression. PMID:24682529

Based on standard screening techniques, sickle retinopathy reportedly occurs in 10% of adolescents with sickle cell disease (SCD). We performed a prospective, observational clinical study to determine if ultra-widefield fluorescein angiography (UWFA), spectral-domain optical coherence tomography (SD-OCT), and optical coherence tomography angiography (OCT-A) detect more-frequent retinopathy in adolescents with SCD. Cross-sectional study. Setting: Institutional. Sixteen adolescents with SCD, aged 10-19 years (mean age 14.9 years), and 5 age-equivalent controls (mean age 17.4 years). Examinations including acuity, standard slit-lamp biomicroscopy, UWFA, SD-OCT, and OCT-A were performed. Sickle retinopathy defined by biomicroscopic changes, Goldberg stages I-V, Penman scale, flow void on OCT-A, or macular thinning on SD-OCT. While 22 of 32 SCD eyes (68.8%) had retinopathy on biomicroscopy, by UWFA 4 of 24 (16.7%) SCD eyes had peripheral arterial occlusion (Goldberg I), and 20 of 24 eyes (83.3%) had peripheral arteriovenous anastomoses (Goldberg II) in addition. No patients had Goldberg stages III-V. By SD-OCT and OCT-A, thinning of the macula and flow voids in both the superficial and deep retinal capillary plexus were found in 6 of 30 (20%) eyes. All 24 eyes with adequate UWFA studies demonstrated sickle retinopathy. SD-OCT and OCT-A, which have not been previously reported in the adolescent population, detected abnormal macular thinning and flow abnormalities undetected by biomicroscopy. These findings suggest that pediatric sickle retinopathy may be more prevalent than previously suspected. If these findings are confirmed with larger cross-sectional and prospective analyses, these approaches may enhance early screening for sickle retinopathy. Copyright © 2017 Elsevier Inc.

Previous studies found that stress, depression, burnout, anxiety, and depersonalisation play a significant role amongst dental and medical students. We wanted to examine if students of the University of Erlangen-Nuremberg also would report elevated values as can been found in similar publications. Furthermore, particularly coping strategies were investigated. The data collection took place in April 2008 including 182 dental and medical students of the 4th and 5th academic year at the University of Erlangen-Nuremberg. Demographic data and the following screening instruments were used: Maslach Burnout Inventory (MBI), Cambridge Depersonalisation Scale (CDS-9), Hospital Anxiety and Depression Scale (HADS), Brief COPE. Descriptive statistics showed higher pathological values in dental students than in medical students. The difference was especially pronounced on the depersonalisation scale (CDS-9), with 20.4% of the dental students, but only 5.5% of the medical students showing scores above a cut-off of 19. The scores decreased in the course of 3 semesters of dentistry. The students with elevated values showed a higher degree of dysfunctional coping. Our results obtained with the screening instruments are in line with the results of previous investigations of other authors and point out the importance of this issue. It might be useful to develop programs teaching dental students more adaptive coping strategies before their first patient contact.

There is no systematic identification of parents with excessive alcohol use who have a child admitted to hospital. Children in families with excessive alcohol issues form a high risk group as substantial alcohol consumption has a damaging influence on a child emotionally, cognitively, socially and physically. Alcohol consumption is a sensitive issue, and health staff needs knowledge, qualifications and adequate training in communicating with parents about this taboo. • To identify specific patterns in subgroups of parents by comparing results from screening and demographic variables • To identify systematic patterns in staff members by demographic variables to decide whether these factors influence the screening results. During 1 year, screening and brief intervention (SBI) was accomplished, including health staff conducting dialogues with parents of a hospitalized child using motivational interviewing (MI) and screening for risky alcohol behaviour by Cut down, Annoyance from others, feel Guilty, Early-morning Craving (CAGE)-C. Data were analysed by descriptive statistics, and relationships were tested with a statistical significance level of 0.05, using SPSS (version 16.0). Motivational dialogues with 779 parents were conducted by 43 staff members, and 11% of the parents were screened positive for risky alcohol behaviour. Drinking alcohol 4 days a week or more and drinking alcohol outside mealtimes were main risk factors. Parents' gender was the strongest predictor of screening positive and OR was 6.8 for men (CI 4.03-11.74) compared to women, p<0.0001. An OR of 1.2 for parents' age (CI 1.02-1.42) indicates the risk of screening positive increases with age, p=0.027. Brief intervention using CAGE-C and MI has proven successful in mapping parents' alcohol consumption patterns and in identifying parents with risky alcohol consumption habits. Health staff is able to manage health promotion and prevention when having the right competences and when being supervised. © 2010 The Authors.

The Edinburgh Postnatal Depression Scale (EPDS) may not be a uniformly valid postnatal depression (PND) screen across populations. We evaluated the performance of a Chinese translation of 10-item (HK-EPDS) and six-item (HK-EPDS-6) versions in post-partum women in Singapore. Chinese-speaking post-partum obstetric clinic patients were recruited for this study. They completed the HK-EPDS, from which we derived the six-item HK-EPDS-6. All women were clinically assessed for PND based on Diagnostic and Statistical Manual, Fourth Edition-Text Revision criteria. Receiver-operator curve (ROC) analyses and likelihood ratio computations informed scale cutoff choices. Clinical fitness was judged by thresholds for internal consistency [α ≥ 0.70] and for diagnostic performance by true-positive rate (>85%), false-positive rate (≤10%), positive likelihood ratio (>1), negative likelihood ratio (<0.2), area under the ROC curve (AUC, ≥90%) and effect size (≥0.80). Based on clinical interview, prevalence of PND was 6.2% in 487 post-partum women. HK-EPDS internal consistency was 0.84. At 13 or more cutoff, the true-positive rate was 86.7%, false-positive rate 3.3%, positive likelihood ratio 26.4, negative likelihood ratio 0.14, AUC 94.4% and effect size 0.81. For the HK-EPDS-6, internal consistency was 0.76. At 8 or more cutoff, we found a true-positive rate of 86.7%, false-positive rate 6.6%, positive likelihood ratio 13.2, negative likelihood ration 0.14, AUC 92.9% and effect size 0.98. The HK-EPDS (cutoff ≥13) and HK-EPDS6 (cutoff ≥8) are fit for PND screening for general population post-partum women. The brief six-item version appears to be clinically suitable for quick screening in Chinese speaking women. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

Local and national financial incentives were introduced in England between 2008 and 2015 to encourage screening and brief alcohol intervention delivery in primary care. We used routine Read Code data and interviews with General Practitioners (GPs) to assess their impact. A sequential explanatory mixed-methods study was conducted in 16 general practices representing 106,700 patients and 99 GPs across two areas in Northern England. Data were extracted on screening and brief alcohol intervention delivery for 2010-11 and rates were calculated by practice incentive status. Semi-structured interviews with 14 GPs explored which factors influence intervention delivery and recording in routine consultations. Screening and brief alcohol intervention rates were higher in financially incentivised compared to non-incentivised practices. However absolute rates were low across all practices. Rates of short screening test administration ranged from 0.05% (95% CI: 0.03-0.08) in non-incentivised practices to 3.92% (95% CI: 3.70-4.14) in nationally incentivised practices. For the full AUDIT, rates were also highest in nationally incentivised practices (3.68%, 95% CI: 3.47-3.90) and lowest in non-incentivised practices (0.17%, 95% CI: 0.13-0.22). Delivery of alcohol interventions was highest in practices signed up to the national incentive scheme (9.23%, 95% CI: 8.91-9.57) and lowest in non-incentivised practices (4.73%, 95% CI: 4.50-4.96). GP Interviews highlighted a range of influences on alcohol intervention delivery and subsequent recording including: the hierarchy of different financial incentive schemes; mixed belief in the efficacy of alcohol interventions; the difficulty of codifying complex conditions; and GPs' beliefs about patient-centred practice. Financial incentives have had some success in encouraging screening and brief alcohol interventions in England, but levels of recorded activity remain low. To improve performance, future policies must prioritise alcohol prevention work within the quality and outcomes framework, and address the values, attitudes and beliefs that shape how GPs' provide care.

Ultra-weak sector, Higgs boson mass, and the dilaton

DOE PAGES

Allison, Kyle; Hill, Christopher T.; Ross, Graham G.

2014-09-26

The Higgs boson mass may arise from a portal coupling to a singlet fieldmore » $$\\sigma$$ which has a very large VEV $$f \\gg m_\\text{Higgs}$$. This requires a sector of "ultra-weak" couplings $$\\zeta_i$$, where $$\\zeta_i \\lesssim m_\\text{Higgs}^2 / f^2$$. Ultra-weak couplings are technically naturally small due to a custodial shift symmetry of $$\\sigma$$ in the $$\\zeta_i \\rightarrow 0$$ limit. The singlet field $$\\sigma$$ has properties similar to a pseudo-dilaton. We engineer explicit breaking of scale invariance in the ultra-weak sector via a Coleman-Weinberg potential, which requires hierarchies amongst the ultra-weak couplings.« less

Delirium disproportionately affects patients with dementia and is associated with adverse outcomes. The diagnosis of delirium superimposed on dementia (DSD), however, can be challenging due to several factors, including the absence of caregivers or the severity of preexisting cognitive impairment. Altered level of consciousness has been advocated as a possible useful indicator of delirium in this population. Here we evaluated the performance of the Richmond Agitation and Sedation Scale (RASS) and the modified-RASS (m-RASS), an ultra-brief measure of the level of consciousness, in the diagnosis of DSD. Multicenter prospective observational study. RASS and m-RASS results were analyzed together, labeled RASS/m-RASS. Acute geriatric wards, in-hospital rehabilitation, emergency department. Patients 65 years and older with dementia. Delirium was diagnosed with the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) or with the Delirium Rating Scale-Revised (DRS-R-98), or with the 4 A's Test (4AT). Dementia was detected with the Clinical Dementia Rating (CDR) Scale, the Short Form-Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) or via the clinical records. Of the 645 patients included, 376 (58%) had delirium. According to the instrument used to evaluate delirium, the prevalence was 66% with the 4AT, 23% with the DSM, and 100% with the DRS-R-98. Overall a RASS/m-RASS score other than 0 was 70.5% sensitive (95% confidence interval [CI] 65.9%-75.1%) and 84.8% (CI 80.5%-89.1%) specific for DSD. Using a RASS/m-RASS value greater than +1 or less than -1 as a cutoff, the sensitivity was 30.6% (CI 25.9%-35.2%) and the specificity was 95.5% (CI 93.1%-98.0%). The sensitivity and the specificity did not greatly vary according to the method of delirium diagnosis and the dementia ascertainment, although the specificity was slightly higher when the DSM and the IQCODE were used. In older patients admitted to different clinical settings, the RASS and m-RASS analyzed as a single group had moderate sensitivity and very high specificity for the detection of DSD. Level of consciousness is therefore a valuable clinical indicator that should form part of delirium screening strategies, although for higher sensitivity other methods of assessment should be used.

The American Medical Association Current Procedural Panel developed a new billing code making behavioral health screening a reimbursable healthcare service. The use of computerized testing as a means for cognitive screening and brief cognitive testing is increasing at a rapid rate. The purpose of this education paper is to provide information to clinicians, healthcare administrators, and policy developers about the purpose, strengths, and limitations of cognitive screening tests versus comprehensive neuropsychological evaluations. Screening tests are generally brief and narrow in scope, they can be administered during a routine clinical visit, and they can be helpful for identifying individuals in need of more comprehensive assessment. Some screening tests can also be helpful for monitoring treatment outcomes. Comprehensive neuropsychological assessments are multidimensional in nature and used for purposes such as identifying primary and secondary diagnoses, determining the nature  and severity of a person's cognitive difficulties, determining functional limitations, and planning treatment and rehabilitation. Cognitive screening tests are expected to play an increasingly important role in identifying individuals with cognitive impairment and in determining which individuals should be referred for further neuropsychological assessment. However, limitations of existing cognitive screening tests are present and cognitive screening tests should not be used as a replacement for comprehensive neuropsychological testing. © The Author 2017.

2017-10-01

To estimate the effects of a brief prenatal behavioral intervention on risk behaviors for maternal cytomegalovirus (CMV) infection. Women were screened with CMV serology during prenatal care before 20 weeks of gestation and followed for at least 10 weeks. Women without serologic evidence of primary CMV infection were approached. Participants were apprised of serostatus and then randomized 2:1 to either a brief behavioral intervention during their prenatal care visit or to standard care (a brochure). The 7- to 10-minute in-office intervention included a video and hygiene education using motivational interviewing. Participants were then given a reminder calendar to take home and weekly text message reminders. The primary outcome was change in behavioral compliance score on a scale of 0-100. Secondary outcomes included process evaluation and domains of behavior change. A sample size of 180 participants was planned to compare the behavioral compliance score change of at least 15% between intervention and control groups with 80% power and 2.5% two-sided α. From April 2013 to October 2014, 197 women were randomized. One hundred eighty-seven (96%) had outcome data available. Mean gestational age at screening and randomization was 9 4/7 and 13 6/7 weeks of gestation, respectively. Primary outcome assessment occurred at a mean of 28 4/7 weeks of gestation. Baseline behavioral compliance scores increased modestly in the intervention group (mean: 7-point increase from 80.7 to 87.7, 95% CI 2.4-5.9) compared with the comparison group (mean: 4-point increase from 79.7 to 84.1, 95% CI 5.9-8.4; mean difference in change score: 3.0, 95% CI, 0.8-5.2; P=.007). Those in the intervention group reported change in risk perception related to perceived severity and susceptibility, self-efficacy, and perceived norms (P<.05 for all). A brief behavioral intervention delivered in the prenatal care setting was modestly effective at changing behaviors related to CMV infection risk. ClinicalTrials.gov, NCT01819519.

This study was designed to explore physical, social/behavioral, and mental health factors among incoming university students with elevated self-reported ADHD symptoms. A total of 5,240 incoming university students were recruited. The test battery included the ADHD Self-Report Scale, the Measurement of Support Functions, the Chinese Internet Addiction Scale-Revision, Quality of Life assessment, the Brief Symptoms Rating Scale, and the 10-item Social Desirability Scale. ADHD symptoms were elevated in 8.6% of the sample. Only individuals with a lower social desirability score, however, were recruited for further analysis. Significant influential factors for higher self-reported levels for ADHD symptoms included greater suicidal ideation and emotional disturbance, as well as a higher Internet addiction tendency, lower levels of social support, and a greater amount of exercise. Given the elevated prevalence of self-reported ADHD symptoms among this sample of university students, screening for these kinds of problems to detect early challenges before students fail in college as well as identify youth with undiagnosed ADHD should be considered. © The Author(s) 2014.

2010-04-01

The aims of this study were to examine evidence for the concurrent validity of two self-report measures and two staff-report measures measuring alcohol and drug problems in seriously mentally ill people and to examine if psychotic patients under-report their alcohol and drug problems in an early intervention clinic. This is a cross-sectional study of 48 patients (26 inpatients and 22 outpatients) from an early intervention clinic for psychosis. To examine the sensitivity and specificity, we compared both the staff-report measures Clinical Alcohol Use Scale (AUS) and Clinical Drug Use Scale (DUS) and the self-report measures Short Michigan Alcohol Screening Test (SMAST-13) and Drug Abuse Screening Test (DAST-20), with the current ICD-10 diagnostic criteria as the gold-standard for alcohol and drug problems. To examine whether the patients under-report their alcohol and drug problems, we also compared the self-report measures SMAST-13 and DAST-20 with the staff-report measures AUS and DUS and ICD-10 consensus substance abuse diagnoses. The results show that the concurrent validity compared with ICD-10 diagnoses was moderate for both the staff-report measures AUS and DUS and for the self-report measures SMAST-13 and DAST-20. Three out of seven patients under-report alcohol problems and one patient out of seven under-report drug use problems according to consensus ICD-10 substance abuse diagnoses. We conclude that the SMAST-13 and DAST-20 in combination with the AUS and DUS, which are easy and quick to perform, are helpful in establishing a common understanding of the patient's alcohol and drug problems in an early intervention clinic.

This study analyzed service unit and annual costs of substance abuse screening, brief intervention, and referral to treatment (SBIRT) programs implemented in emergency department (ED), inpatient, and outpatient medical settings in three U.S. states and one tribal organization. Unit costs and annual costs were estimated from the perspective of service providers. Data for unit costs came from 26 performance sites, and data for annual costs came from 10 programs. A bottom-up approach was used to derive unit costs and included labor, space, and materials used in each SBIRT activity. Activities included direct SBIRT services and activities that support direct service delivery. Labor time spent in each activity was collected by trained observers using a time-and-motion approach. A top-down approach used cost questionnaires completed by program administrators to calculate annual costs and included labor, space, contracted services, overhead, training, travel, equipment, and supplies and materials. Costs were estimated in 2012 U.S. dollars. Average unit costs for prescreening, screening, brief intervention, brief treatment, and referral to treatment were $0.61, $6.59, $10.48, $22.63, and $12.06 in ED; $0.86, $6.33, $9.07, $27.61, and $8.03 in inpatient; and $0.84, $3.98, $7.81, $27.94, and $9.23 in outpatient settings, respectively; over half of the costs were attributable to support activities. Across all settings, the average cost to provide SBIRT per positive screen, for 1year, was about $400. Support activities comprise a large proportion of costs. Health administrators can use the results to budget and compare how much sites are reimbursed for SBIRT to how much services actually cost. Copyright © 2015 Elsevier Inc. All rights reserved.

Can a single question effectively screen for burnout in Australian cancer care workers?

2010-01-01

Background Burnout has important clinical and professional implications among health care workers, with high levels of burnout documented in oncology staff. The aim of this study was to ascertain how well a brief single-item measure could be used to screen for burnout in the Australian oncology workforce. Methods During 2007, 1322 members of the Clinical Oncological Society of Australia were invited to participate in a cross-sectional nationwide survey; 740 (56%) of eligible members consented and completed the survey. Data from the 638 consenting members who reported that their work involved direct patient contact were included in the secondary analyses reported in this paper. Burnout was assessed using the MBI Human Services Survey Emotional Exhaustion sub-scale and a single-item self-defined burnout scale. Results Emotional exhaustion was "high" in 33% of the sample when assessed by the psychometrically validated MBI. The single-item burnout measure identified 28% of the sample who classified themselves as "definitely burning out", "having persistent symptoms of burnout", or "completely burned out". MBI Emotional Exhaustion was significantly correlated with the single-item burnout measure (r = 0.68, p < 0.0001) and an ANOVA yielded an R2 of 0.5 (p < 0.0001). Conclusions The moderate to high correlation between the single-item self-defined burnout measure and the emotional exhaustion component of burnout suggest that this single item can effectively screen for burnout in health care settings which are time-poor for assessing burnout more comprehensively.

The Clock-Drawing Test (CDT) is a brief, relatively time-efficient, easy to administer at bedside, and well-proven cognitive screening test that assesses a broad range of cognitive abilities in stroke, delirium, and dementia. However, challenges of comprehensive therapeutic outcome evaluations in schizophrenia can also be potentially overcome using CDT. The authors aimed to measure the therapeutic outcome using CDT in 101 schizophrenia patients, irrespective of their diagnostic subtypes. A repeated measures analysis of variance found that improvements on CDT and the Positive and Negative Syndrome Scale were closely correlated, reflecting critical information about therapeutic response measures in schizophrenia.

Neuropathy is the most common neurologic complication of HIV but is widely under-diagnosed in resource-constrained settings. We aimed to identify tools that accurately distinguish individuals with moderate/severe peripheral neuropathy and can be administered by non-physician healthcare workers (HCW) in resource-constrained settings. We enrolled a convenience sample of 30 HIV-infected outpatients from a Kenyan HIV-care clinic. A HCW administered the Neuropathy Severity Score (NSS), Single Question Neuropathy Screen (Single-QNS), Subjective Peripheral Neuropathy Screen (Subjective-PNS), and Brief Peripheral Neuropathy Screen (Brief-PNS). Monofilament, graduated tuning fork, and two-point discrimination examinations were performed. Tools were validated against a neurologist's clinical assessment of moderate/severe neuropathy. The sample was 57% male, mean age 38.6 years, and mean CD4 count 324 cells/µL. Neurologist's assessment identified 20% (6/30) with moderate/severe neuropathy. Diagnostic utilities for moderate/severe neuropathy were: Single-QNS--83% sensitivity, 71% specificity; Subjective-PNS-total--83% sensitivity, 83% specificity; Subjective-PNS-max and NSS--67% sensitivity, 92% specificity; Brief-PNS--0% sensitivity, 92% specificity; monofilament--100% sensitivity, 88% specificity; graduated tuning fork--83% sensitivity, 88% specificity; two-point discrimination--75% sensitivity, 58% specificity. Pilot testing suggests Single-QNS, Subjective-PNS, and monofilament examination accurately identify HIV-infected patients with moderate/severe neuropathy and may be useful diagnostic tools in resource-constrained settings.

We aimed to assess and compare the psychometric properties of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), Hospital Anxiety and Depression Scale Depression Subscale (HADS-D), and Beck Depression Inventory (BDI) as screening instruments for depression and suicidality in people with epilepsy. One hundred twenty-six people (54% women) diagnosed with epilepsy were recruited and evaluated on their sociodemographic and clinical features. Depression and suicide risk were assessed with a structured psychiatric interview, the Mini International Neuropsychiatric Interview (MINI-Plus), and the performance of NDDI-E, HADS-D, and BDI was evaluated. The sensitivity and specificity of BDI for the diagnosis of depression was around 90%; HADS-D and NDDI-E have sensitivity higher than 80%, and specificity was greater than 75%. For identifying suicide risk, the NDDI-E sensitivity was 92.9%, and HADS-D sensitivity was 85.7%, and a reasonable specificity (68%) was observed for both instruments. All instruments showed a negative predictive value of over 90%. Comparisons of the areas under the ROC curve for these instruments were not significantly different regarding depression or moderate/severe risk of suicide. All three instruments evaluated have clinical utility in the screening of depression in people with epilepsy. Both NDDI-E and HADS-D are brief efficient screening instruments to identify depression in people with epilepsy. The BDI is a more robust instrument, but it takes longer to apply, which hampers its use by busy clinicians and by people with cognitive impairment. Copyright © 2014 Elsevier Inc.

Objectives The International HIV Dementia Scale (IHDS) was developed to screen for HIV-associated dementia (HAD), but it has been used more generally for HIV-associated neurocognitive disorder (HAND). This study sought to examine the accuracy of the IHDS in a cohort of Brazilian HIV-infected individuals and compare its performance to an alternative screening battery for detecting HAND. Methods 108 participants (including 60 HIV-infected persons), completed the IHDS and a gold standard neuropsychological (NP) battery of 17 tests. As alternative screening method, all possible three-test combinations from the NP battery were examined and a superiority index (a marker of specificity and sensitivity) was calculated. Results Sensitivity and specificity to HAND using the standard IHDS cutpoint of 10 were 36% and 75% respectively. The best balance between sensitivity and specificity was accomplished with a modified cutpoint of 11.5, which yielded sensitivity of 72% and specificity of 58%. The top two most sensitive test combinations, compared to the gold standard NP battery, were Trail Making Test A, WAIS-III Digit Symbol (DS) and HVLT-R Total Recall (sensitivity 91%, specificity 96%), and DS, BVMT-R Total Recall and Grooved Pegboard Test-Dominant Hand (sensitivity 94%, specificity 91%). Conclusions Both test combinations can be administered in under 10 minutes and were more accurate than the IHDS in classifying HIV+ participants as NP impaired or unimpaired. These data suggest that demographically corrected T-scores from commonly used NP measures with modest time and material demands can improve identification of patients with HAND who may benefit from a more extensive NP examination.

A broad forensic screening method for 256 analytes in whole blood based on a fully automated SPE robotic extraction and ultra-high-performance liquid chromatography (UHPLC) with TOF-MS with data-independent acquisition has been developed. The limit of identification was evaluated for all 256 compounds and 95 of these compounds were validated with regard to matrix effects, extraction recovery, and process efficiency. The limit of identification ranged from 0.001 to 0.1 mg/kg, and the process efficiency exceeded 50% for 73 of the 95 analytes. As an example of application, 1335 forensic traffic cases were analyzed with the presented screening method. Of these, 992 cases (74%) were positive for one or more traffic-relevant drugs above the Danish legal limits. Commonly abused drugs such as amphetamine, cocaine, and frequent types of benzodiazepines were the major findings. Nineteen less frequently encountered drugs were detected e.g. buprenorphine, butylone, cathine, fentanyl, lysergic acid diethylamide, m-chlorophenylpiperazine, 3,4-methylenedioxypyrovalerone, mephedrone, 4-methylamphetamine, p-fluoroamphetamine, and p-methoxy-N-methylamphetamine. In conclusion, using UHPLC-TOF-MS screening with data-independent acquisition resulted in the detection of common drugs of abuse as well as new designer drugs and more rarely occurring drugs. Thus, TOF-MS screening of blood samples constitutes a practical way for screening traffic cases, with the exception of δ-9-tetrahydrocannabinol, which should be handled in a separate method. © 2013 WILEY-VCH Verlag GmbH & Co.

To develop and evaluate a brief observational measure of clinical risk communication competence. A 4-item checklist-type measure, the BRISK (Brief Risk Information Skill) Scale, was developed by selecting and refining items from a more comprehensive measure of clinical risk communication competence. Six volunteer raters received brief training on the measure and then used the BRISK Scale to evaluate 52 video-recorded encounters between 2nd-year medical students and standardized patients conducted as part of an Observed Structured Clinical Examination (OSCE) involving a risk communication task. Internal consistency reliability, inter-rater reliability, and criterion validity were assessed. Raters reported no difficulties using the BRISK Scale; scores across all raters and subjects ranged from 0 to 16 with a mean score of 6.49 (SD=3.17). The BRISK Scale showed good internal consistency reliability (α=0.64), and inter-rater reliability at the scale level (Intraclass Correlation Coefficient (ICC)=0.79 for consistency, and 0.75 for absolute agreement) and individual-item level (ICC range: 0.62-.91). Novice raters' BRISK Scale scores were highly correlated (r=0.84, p<0.01) with expert raters' scores on the Risk Communication Content measure, a more comprehensive measure of risk communication competence. The BRISK Scale is a promising new brief observational measure of clinical risk communication competence. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

THE HUMAN BEHAVIOR RATING SCALE-BRIEF: A TOOL TO MEASURE 21ST CENTURY SKILLS OF K-12 LEARNERS.

2015-06-01

Currently there is a call for brief concise measurements to appraise relevant 21st century college readiness skills in K-12 learners. This study employed K-12 teachers' ratings for over 3,000 students for an existing 91-item rating scale, the Human Behavior Rating Scale, that measured the 21st century skills of persistence, curiosity, externalizing affect, internalizing affect, and cognition. Teachers' ratings for K-12 learners were used to develop a brief, concise, and manageable 30-item tool, the Human Behavior Rating Scale-Brief. Results yielded high internal consistency coefficients and inter-item correlations. The items were not biased with regard to student sex or race, and were supported through confirmatory factor analyses. In addition, when teachers' ratings were compared with students' academic and behavioral performance data, moderate to strong relationships were revealed. This study provided an essential first step in the development of a psychometrically sound, manageable, and brief tool to appraise 21st century skills in K-12 learners.

The purpose of this study was to address critical gaps in behavioral health care of youth with epilepsy by examining the utility of a brief, well-validated screening instrument, the PSC-17, in a pediatric population with epilepsy. One hundred eighty-seven caregivers of youth with epilepsy ages 2-17years completed the PSC-17 for their child/adolescent during a routine epilepsy visit. Demographic and seizure information was abstracted from electronic medical record review. Confirmatory factor analyses for the PSC-17 revealed an acceptable fit with the 3-factor model, χ(2) (116 [N=187]=204.54, p<0.001, CFI=0.90, TLI=0.88, RMSEA=0.064, SRMSR=0.078). Scale level reliabilities were excellent (0.72-0.85). Interscale correlations were moderate (0.48-0.69). Approximately 1/5th of the sample met clinical cut-offs for the total score of behavioral health concerns. However, an additional 20% of the sample had at least one elevated subscale score despite the total score being in the normative/nonclinical range. The PSC-17 is a brief, free behavioral health screening tool with adequate to strong validity, reliability, and clinical utility for pediatric populations with epilepsy. Clinicians should consider using the 3 PSC-17 subscale scores instead of the total score to guide referrals for further evaluation as the subscales may provide a more accurate picture of functioning in particular domains.

3D X-ray ultra-microscopy of bone tissue.

2016-02-01

We review the current X-ray techniques with 3D imaging capability at the nano-scale: transmission X-ray microscopy, ptychography and in-line phase nano-tomography. We further review the different ultra-structural features that have so far been resolved: the lacuno-canalicular network, collagen orientation, nano-scale mineralization and their use as basis for mechanical simulations. X-ray computed tomography at the micro-metric scale is increasingly considered as the reference technique in imaging of bone micro-structure. The trend has been to push towards increasingly higher resolution. Due to the difficulty of realizing optics in the hard X-ray regime, the magnification has mainly been due to the use of visible light optics and indirect detection of the X-rays, which limits the attainable resolution with respect to the wavelength of the visible light used in detection. Recent developments in X-ray optics and instrumentation have allowed to implement several types of methods that achieve imaging that is limited in resolution by the X-ray wavelength, thus enabling computed tomography at the nano-scale. We review here the X-ray techniques with 3D imaging capability at the nano-scale: transmission X-ray microscopy, ptychography and in-line phase nano-tomography. Further, we review the different ultra-structural features that have so far been resolved and the applications that have been reported: imaging of the lacuno-canalicular network, direct analysis of collagen orientation, analysis of mineralization on the nano-scale and use of 3D images at the nano-scale to drive mechanical simulations. Finally, we discuss the issue of going beyond qualitative description to quantification of ultra-structural features.

Ultra-High-Throughput Screening of an In Vitro-Synthesized Horseradish Peroxidase Displayed on Microbeads Using Cell Sorter

The C1a isoenzyme of horseradish peroxidase (HRP) is an industrially important heme-containing enzyme that utilizes hydrogen peroxide to oxidize a wide variety of inorganic and organic compounds for practical applications, including synthesis of fine chemicals, medical diagnostics, and bioremediation. To develop a ultra-high-throughput screening system for HRP, we successfully produced active HRP in an Escherichia coli cell-free protein synthesis system, by adding disulfide bond isomerase DsbC and optimizing the concentrations of hemin and calcium ions and the temperature. The biosynthesized HRP was fused with a single-chain Cro (scCro) DNA-binding tag at its N-terminal and C-terminal sites. The addition of the scCro-tag at both ends increased the solubility of the protein. Next, HRP and its fusion proteins were successfully synthesized in a water droplet emulsion by using hexadecane as the oil phase and SunSoft No. 818SK as the surfactant. HRP fusion proteins were displayed on microbeads attached with double-stranded DNA (containing the scCro binding sequence) via scCro-DNA interactions. The activities of the immobilized HRP fusion proteins were detected with a tyramide-based fluorogenic assay using flow cytometry. Moreover, a model microbead library containing wild type hrp (WT) and inactive mutant (MUT) genes was screened using fluorescence-activated cell-sorting, thus efficiently enriching the WT gene from the 1:100 (WT:MUT) library. The technique described here could serve as a novel platform for the ultra-high-throughput discovery of more useful HRP mutants and other heme-containing peroxidases. PMID:25993095

Adolescent substance involvement use and abuse.

2014-09-01

Substance use in adolescence is common, but not all use indicates a substance use disorder. The primary care provider has an essential role in screening for substance involvement, assessing the level of substance use and its impact on function, and engaging in a brief intervention to encourage and support behavioral change related to substance use. This article summarizes the literature on adolescent vulnerability to substance use disorders and their impact on adolescent health and well-being. Practical concrete suggestions for approaches to screening, brief interventions, and referral to treatment provide a stepwise approach to adolescent substance use assessment and intervention.

HIV-associated sensory neuropathy (HIV-SN) is a frequent complication of HIV infection and a major source of morbidity. A cross-sectional deep profiling study examining HIV-SN was conducted in people living with HIV in a high resource setting using a battery of measures which included the following: parameters of pain and sensory symptoms (7 day pain diary, Neuropathic Pain Symptom Inventory [NPSI] and Brief Pain Inventory [BPI]), sensory innervation (structured neurological examination, quantitative sensory testing [QST] and intraepidermal nerve fibre density [IENFD]), psychological state (Pain Anxiety Symptoms Scale-20 [PASS-20], Depression Anxiety and Positive Outlook Scale [DAPOS], and Pain Catastrophizing Scale [PCS], insomnia (Insomnia Severity Index [ISI]), and quality of life (Short Form (36) Health Survey [SF-36]). The diagnostic utility of the Brief Peripheral Neuropathy Screen (BPNS), Utah Early Neuropathy Scale (UENS), and Toronto Clinical Scoring System (TCSS) were evaluated. Thirty-six healthy volunteers and 66 HIV infected participants were recruited. A novel triumvirate case definition for HIV-SN was used that required 2 out of 3 of the following: 2 or more abnormal QST findings, reduced IENFD, and signs of a peripheral neuropathy on a structured neurological examination. Of those with HIV, 42% fulfilled the case definition for HIV-SN (n = 28), of whom 75% (n = 21) reported pain. The most frequent QST abnormalities in HIV-SN were loss of function in mechanical and vibration detection. Structured clinical examination was superior to QST or IENFD in HIV-SN diagnosis. HIV-SN participants had higher plasma triglyceride, concentrations depression, anxiety and catastrophizing scores, and prevalence of insomnia than HIV participants without HIV-SN. PMID:24973717

Screening and treatment for substance use among people living with HIV/AIDS (PLWHA) is highly recommended. Nevertheless, in Peru healthcare for PLWHA does not include a standardized or systematic assessment to identify substance use. The aim of this study was to assess the feasibility of implementing screening, brief intervention and referral to treatment (SBIRT) in healthcare settings attending people living with PLWHA. After providing training in SBIRT for PLWHA's healthcare personnel (including nurses and physicians) focus groups were conducted to explore knowledge, beliefs and perceived barriers to implementation and interviews were conducted to assess the barriers and facilitators of two tertiary hospitals in Lima, Peru. focus groups and interviews' thematic coding revealed three dimensions: 1) the unknown extent of substance use within PLWHA, 2) space and time limitations hinder completion of brief interventions during routine visits, and 3) insufficient access to substance use treatment appropriate for HIV patients. Multiple barriers, including lack of awareness of substance use problems, limited space and time of providers, and lack of specialized services to refer patients for treatment make it difficult to implement SBIRT in the Peruvian healthcare system.

Part 2: Screening, Brief Intervention and Referral to Treatment Plus Recovery Management: A Proposed Model for Recovery-Oriented Primary Care.

Fornili, Katherine S

2016-01-01

Part 1 of this two-part series (The Theoretical Basis for Recovery-Oriented Management of Substance Use Disorders in the Primary Care) explored the theoretical foundations for evidence-based substance Screening, Brief Intervention and Referral to Treatment (SBIRT) services. The aim was to produce possible explanations for why traditional SBIRT works well for individuals with unhealthy alcohol use but not as well for individuals who have more serious substance use disorders, including drug use and alcohol/drug dependence. Building on that analysis, through meaningful application of recovery management (RM) concepts within an integrated primary care/behavioral health context, a new, theory-based, recovery-oriented framework for primary care SBIRT is now introduced in Part 2. The proposed SBIRT Plus Recovery Management (SBIRT + RM) model moves traditional SBIRT from its original, limited, and narrow focus only on substance detection, brief intervention, and referral to its rightful, structured placement within a comprehensive, multidimensional, recovery-oriented system of care clinical practice environment. SBIRT+RM describes relevant strategies for improving recovery outcomes for individuals identified through primary care substance screening and defines primary care provider roles and responsibilities for sustained recovery support and long-term recovery maintenance.

Alcohol use patterns that are hazardous for one's health is prevalent among DWI (driving while intoxicated) offenders and is a key predictor of recidivism. The aim of this program evaluation was to determine the feasibility and usability of implementing a computer-assisted screening, brief intervention and referral to treatment (SBIRT) program for DWI offenders to enable the identification of those in need of treatment services soon after arrest. Our treatment program consisted of a web-based, self-guided screening tool for assessing alcohol use patterns and generating a personalized feedback report that is then used to deliver a brief motivational intervention and if needed, a referral to treatment. Between August and November 2014, all DWI offenders attending orientation for pre-trial supervision were assessed for eligibility. Of the 129 eligible offenders, 53.5 percent enrolled and the first 50 were asked to complete a usability and satisfaction questionnaire. The results demonstrated that the majority of those screened reported at-risk alcohol use patterns requiring referral to treatment. Clients reported high ratings of usability and satisfaction with the screening tool and personalized feedback report, which did not significantly differ depending on alcohol use patterns. There were relatively few technical difficulties, and the majority of clients reported high levels of satisfaction with the overall SBIRT program. Results of this program evaluation suggest that computer-assisted SBIRT may be successfully implemented within the criminal justice system to DWI offenders soon after arrest; however, further research is required to examine its effects on treatment utilization and recidivism.

The bacterial toxins Staphylococcus aureus alpha-hemolysin and Bacillus anthracis protective antigen kill cells in part by forming ion channels in target membranes. We are using electrophysiology, molecular biology/protein biochemistry and computer modeling to study how biopolymers (e.g., single-stranded DNA and proteins) bind to and transport through these nanometer-scale pores. The results provide insight into the mechanism by which these toxins work and are the basis for several potential nanobiotechnology applications including ultra-rapid DNA sequencing, the sensitive and selective detection of a wide range of analytes and high throughput screening of therapeutic agents against several anthrax toxins.

Various facts demonstrated that UVB is harmful to organisms. Sunscreen compounds are usually used to prevent the excessive damage caused by UVB. However, certain photosynthetic organisms have evolved mechanisms to counteract the toxicity of ultraviolet radiation by synthesizing UV screening compounds such as mycosporine-like amino acids (MAAs). MAAs provide UV protection to primary and secondary consumers through food chain and to non-biological materials by photostabilizing action. Information related to the ecological consequence of MAAs and their spatial distribution from a wide range of organisms is accumulating. Hence, our studies seek a potent class of natural sun protective compounds to understand their relationship with environment and to develop a protocol for large-scale industrial production of these compounds so that they can find application as UV-protecting cosmetics.

Multiple system atrophy (MSA) is a rare progressive neurodegenerative disorder for which brief yet sensitive scale is required in order for use in clinical trials and general screening. We previously compared several scales for the assessment of MSA symptoms and devised an eight-item pilot scale with large standardized response mean [handwriting, finger taps, transfers, standing with feet together, turning trunk, turning 360°, gait, body sway]. The aim of the present study is to investigate the validity and reliability of a simple pilot scale for assessment of multiple system atrophy symptoms. Thirty-two patients with MSA (15 male/17 female; 20 cerebellar subtype [MSA-C]/12 parkinsonian subtype [MSA-P]) were prospectively registered between January 1, 2014 and February 28, 2015. Patients were evaluated by two independent raters using the Unified MSA Rating Scale (UMSARS), Scale for Assessment and Rating of Ataxia (SARA), and the pilot scale. Correlations between UMSARS, SARA, pilot scale scores, intraclass correlation coefficients (ICCs), and Cronbach's alpha coefficients were calculated. Pilot scale scores significantly correlated with scores for UMSARS Parts I, II, and IV as well as with SARA scores. Intra-rater and inter-rater ICCs and Cronbach's alpha coefficients remained high (> 0.94) for all measures. The results of the present study indicate the validity and reliability of the eight-item pilot scale, particularly for the assessment of symptoms in patients with early state multiple system atrophy.

There is some evidence that people with intellectual disabilities who live in the community are exposed to the same risks of alcohol use as the rest of the population. Various interventions have been evaluated in the general population to tackle hazardous or harmful drinking and alcohol dependence, but the literature evaluating interventions is very limited regarding intellectual disabilities. The National Institute for Health and Clinical Excellence recommends that brief and extended brief interventions be used to help young persons and adults who have screened as positive for hazardous and harmful drinking. The objective of this trial is to investigate the feasibility of adapting and delivering an extended brief intervention (EBI) to persons with mild/moderate intellectual disability who live in the community and whose level of drinking is harmful or hazardous. The study has three stages, which include the adaptation of the Extended Brief Intervention (EBI) for people with intellectual disability, a single blind, randomised controlled trial of an individual Extended Brief Intervention to test the feasibility of the intervention, and a qualitative study that will assess the perceived acceptability and usefulness of the intervention. Fifty participants in total will be recruited from community intellectual disability services and social care or third sector organisations. The main outcome is a reduction in alcohol consumption measured by the Alcohol Use Disorders Identification Test. Alcohol misuse is a relatively under-researched mental health problem in people with intellectual disabilities. Therefore, the study addresses both diagnostic issues and the delivery of a simple first stage intervention, which is available to the population of average intelligence and young persons in particular. The findings from the study will guide the preparation of a large-scale study to test whether this treatment is clinically and cost-effective in this population. ISRCTN58783633 (19 December 2013).

Like other complex psychosocial interventions, mindfulness-based treatments comprise various modality-specific components as well as nonspecific therapeutic ingredients that collectively contribute to efficacy. Consequently, the isolated effects of mindfulness strategies per se remain unclear. Using a randomized double-blind design, we compared the isolated effects of 11-minutes of "supervised" mindfulness instruction against a closely matched active control (relaxation) on subjective, physiological, and behavioral indices of maladaptive alcohol responding in drinkers at risk of harm from alcohol use (n = 68). Simple follow-up instructions on strategy use were provided, but practice was unsupervised and not formally monitored. Both groups showed acute reductions in craving after training, although a trend group x time interaction (P = .056) suggested that this reduction was greater in the relaxation group (d = 0.722 P < .001) compared with the mindfulness group (d = 0.317, P = .004). Furthermore, upregulation of parasympathetic activity was found after relaxation (d = 0.562; P < .001) but not mindfulness instructions (d = 0.08; P > .1; group x time interaction: P = .009). By contrast, only the mindfulness group showed a reduction in past-week alcohol consumption at 7-day follow-up (-9.31 units, d = 0.593, P < .001), whereas no significant reduction was seen in the relaxation group (-3.00 units, d = 0.268, P > .1; group x time interaction: P = .026). Very brief mindfulness practice can significantly reduce alcohol consumption among at-risk drinkers, even with minimal encouragement to use this strategy outside of the experimental context. The effects on consumption may therefore represent a lower bound of efficacy of "ultra-brief" mindfulness instructions in hazardous drinkers, at least at short follow-up intervals. © The Author 2017.

Unhealthy substance use is associated with increased rates of STDs, including HIV. Within three high-risk New York City (NYC) sexual health clinics between 2008 and 2012 (n = 146,657), 17% of patients screened positive for a current SUD but only 5.3% ever received prior treatment. The goal of Project Renew was to expand the reach of substance use early intervention services within and across sexual health clinics citywide and decrease substance use, poor mental health, and risky sexual behavior. To accomplish this goal, Screening, Brief Intervention, and Referral to Treatment (SBIRT), an evidence-based substance use early intervention model, was implemented in all eight NYC sexual health clinics February 2012-January 2015. Clinic patients were screened for substance misuse using the AUDIT/DAST-10, and those who screened positive were eligible for on-site brief intervention. Overall, 130,597 substance misuse screenings were conducted (66,989, or 51%, positive), and 17,474 on-site brief interventions and 1238 referrals were provided (not unique to individual patients). A 10% sample of 14,709 unique patients who screened positive were interviewed using a federal data collection tool at baseline and six months later to assess changes in substance use, sexual risk behaviors, mental health, and health status (n = 1328). At six-month follow-up, patients reported reduced substance use, less sexual activity, improved overall health, and fewer days of depression and anxiety compared to measures at baseline (p < 0.05). Based on positive results, Project Renew SBIRT services have been sustained, ensuring essential care which may help prevent acquisition of HIV/STDs among a large population of high-risk New Yorkers.

Valois, Robert F; Zullig, Keith J

2013-10-01

Preliminary data were collected to evaluate the psychometric properties of an emotional self-efficacy (ESE) measure in a sample of 3836 public high school adolescents who completed the Centers for Disease Control and Prevention (CDC) Youth Risk Behavior Survey in South Carolina. Principal axis factor analysis was followed by a 4-way between-groups analysis of variance (ANOVA) testing for differences in total score means on selected demographic estimates and their interactions. Relationships between total score and selected risk behaviors were examined through a series of 1-way ANOVA procedures and subsequent Tukey Honest Significant Difference (HSD) tests. Factor analysis results suggested that a 1-factor model best explained factor structure of the scale items (factor loadings .64 to .71, eigenvalue = 3.24, h(2)  = .46). Girls reported a significantly higher mean total ESE rating than boys; White students reported a significantly higher mean total ESE rating than Black students. Statistically significant lower mean total ESE ratings were also noted for those who reported physical fighting, lifetime alcohol use, and sexual intercourse. This 7-item scale is a reliable measure and could aid school health researchers and mental health practitioners in psychosocial screening and as an outcome of social and emotional learning as a brief measure of adolescent ESE. © 2013, American School Health Association.

Aims: Large-scale epidemiological studies show a significant prevalence of gambling disorder (GD) during adolescence and emerging adulthood, and highlight the need to identify gambling-related behaviors at early ages. However, there are only a handful of screening instruments for this population and many studies measuring youth gambling problems use adult instruments that may not be developmentally appropriate. The aim of this study was to validate a Spanish version of the Canadian Adolescent Gambling Inventory (CAGI) among late adolescent and young adults and to explore its psychometric properties. Methods: The sample (16–29 years old) included a clinical group (n = 55) with GD patients and a control group (n = 340). Results: Exploratory factor analysis yielded one factor as the best model. This 24-item scale demonstrated satisfactory reliability (internal consistency, Cronbach’s alpha, α = 0.91), satisfactory convergent validity as measured by correlation with South Oaks Gambling Screen (r = 0.74), and excellent classification accuracy (AUC = 0.99; sensitivity = 0.98; and specificity = 0.99). Conclusion: Our results provide empirical support for our validation of the Spanish version of the CAGI. We uphold that the Spanish CAGI can be used as a brief, reliable, and valid instrument to assess gambling problems in Spanish youth. PMID:28223961

Cognitive impairment occurs in up to 80% of patients with heart failure (HF). The National Institute for Neurological Disorders and Stroke (NINDS) and the Canadian Stroke Network (CSN) recommend a 5-minute cognitive screening protocol that has yet to be psychometrically evaluated in HF populations. The aim of this study was to conduct a secondary analysis of the sensitivity and specificity of the NINDS-CSN brief cognitive screening protocol in HF patients. The Montreal Cognitive Assessment (MoCA) was administered to 221 HF patients. The NINDS-CSN screen comprises 3 MoCA items, with lower scores indicating poorer cognitive function. Receiver operator characteristic (ROC) curves were constructed, determining the sensitivity, specificity and appropriate cutoff scores of the NINDS-CSN screen. In an HF population aged 76 ± 12 years, 136 (62%) were characterized with cognitive impairment (MoCA <26). Scores on the NINDS-CSN screen ranged from 3-11. The area under the receiver operating characteristic curve indicated good accuracy in screening for cognitive impairment (0.88; P < .01; 95% CI 0.83-0.92). A cutoff score of ≤9 provided 89% sensitivity and 71% specificity. The NINDS-CSN protocol offers clinicians a feasible telephone method to screen for cognitive impairment in patients with HF. Future studies should include a neuropsychologic battery to more comprehensively examine the diagnostic accuracy of brief cognitive screening protocols. Copyright © 2016 Elsevier Inc.

2017-03-01

Introduction Legal highs also known as novel psychoactive substances mimic the effects of classic drugs of abuse. Challenges to developing screening services for novel psychoactive substances include identifying which novel psychoactive substances are available to target. Using new techniques such as exact mass time of flight can help identify common novel psychoactive substances to target for screening patient samples by routine methods such as tandem mass spectrometry. We demonstrate this strategy working in our own clinical toxicology laboratory after qualitative analysis of 98 suspect materials for novel psychoactive substances by ultra-performance liquid chromatography with time of flight mass spectrometry. Results From July 2014 to July 2015 we received 98 requests to test a range of different suspect materials for novel psychoactive substances including herbs, tobacco, liquids, pills and powders. Overall, 87% of the suspect materials tested positive for novel psychoactive substances, and 15% for controlled drugs. Three common novel psychoactive substances were present in 74% of the suspect materials: methiopropamine, a methamphetamine analogue; ethylphenidate, a cocaine mimic; and the third generation synthetic cannabinoid 5F-AKB-48. For the 55 branded products we tested only 24% of the stated contents matched exactly the compounds we detected. Conclusion Testing suspect materials using ultra-performance liquid chromatography with time of flight mass spectrometry has identified three common novel psychoactive substances in use in the UK, simplifying the development of a relevant novel psychoactive substances screening service to our population. By incorporating this into our routine liquid chromatography tandem mass spectrometry drugs of abuse screen, then offers a clinically relevant novel psychoactive substances service to our users. This strategy ensures our clinical toxicology service continues to remain effective to meet the challenges of the changing drug use in the UK.

Systematic screening is recommended for major depressive episode (MDE) with the Neurological Disorders Depression Inventory for Epilepsy NDDI-E, 6 items and generalized anxiety disorder (GAD) with the GAD 7 items in patients with epilepsy (PWE). Shorter versions of the NDDI-E and the GAD-7 could facilitate increased screening by busy clinicians and be more accessible to patients with mild cognitive and/or language impairments. The effectiveness of ultra-short versions of the NDDI-E (2 items) and the GAD-7 (the GAD-2, 2 items, and the GAD-SI with a single item) in comparison with the original versions were statistically tested using ROC analysis. ROC analysis of the NDDIE-2 showed an AUC of 0.926 (p<0.001), a sensitivity of 81.82% and a specificity of 89.16%, without significant difference with the NDDI-E (z=1.582, p=0.11). ROC analysis of the GAD-SI showed an AUC of 0.872 (p<0.001), a sensitivity of 83.67% and a specificity of 82.29%, without significant difference with the GAD-7 (z=1.281, p=0.2). The GAD-2 showed poorer psychometric properties. The limitation is the use of data from previously reported subjects in a single language version, the NDDIE-2 that lacks detection of dysphoric symptoms in comparison with the NDDIE-6 and the GAD-SI that exhibited a more than 10% lower sensitivity than the GAD-7. This study highlights the potential utility of the NDDIE-2 and the GAD-SI as ultra-short screening tools for MDE and GAD respectively in PWE. Further studies in a larger population, including multi-lingual versions, could be a valuable next step. However, the brevity and simplicity of this tool could be an advantage in PWE who present cognitive difficulties, especially attentional or language deficits. Copyright © 2017 Elsevier B.V.

Pharmacoperones correct the folding of otherwise misfolded protein mutants, restoring function (i.e., providing "rescue") by correcting their trafficking. Currently, most pharmacoperones possess intrinsic antagonist activity because they were identified using methods initially aimed at discovering such functions. Here, we describe an ultra-high-throughput homogeneous cell-based assay with a cAMP detection system, a method specifically designed to identify pharmacoperones of the vasopressin type 2 receptor (V2R), a GPCR that, when mutated, is associated with nephrogenic diabetes insipidus. Previously developed methods to identify compounds capable of altering cellular trafficking of V2R were modified and used to screen a 645,000 compound collection by measuring the ability of library compounds to rescue a mutant hV2R [L83Q], using a cell-based luminescent detection system. The campaign initially identified 3734 positive modulators of cAMP. The confirmation and counterscreen identified only 147 of the active compounds with an EC50 of ≤5 µM. Of these, 83 were reconfirmed as active through independently obtained pure samples and were also inactive in a relevant counterscreen. Active and tractable compounds within this set can be categorized into three predominant structural clusters, described here, in the first report detailing the results of a large-scale pharmacoperone high-throughput screening campaign. © 2016 Society for Laboratory Automation and Screening.

This pilot study explores the effects of a brief individual psychoanalytic therapy on perinatal depressive symptoms. This intervention is based on the Geneva's mother-infant intervention model. A sample of 129 pregnant women was recruited in Geneva (Switzerland) and screened for depressive symptoms with two instruments: the 'Edinburgh postnatal depression scale' (EPDS) and the 'Dépistage anténatal de la dépression postnatale'. A group of 40 women presenting depressive symptoms (treatment group) participated in a four-session intervention called 'Psychotherapy centred on parenthood (PCP)'. It consists in two antenatal and two postnatal sessions and is focussed on changing problematic representations of parenthood. This treatment group was compared to a control group of 88 women without depressive symptoms and following the usual obstetrical care. The main outcome measure was EPDS at 3 and 6 months after delivery. The 'Global assessment functioning scale' was administered at the end of each therapeutic session. The 'Parent-infant relationship global assessment scale' was administered at the two postnatal sessions in order to explore if PCP was also effective in preventing the potential negative effects of depression on mother-infant relationship. Results show that in the treatment group (N = 31), EPDS scores dropped from 12.8 to 4.8; none of these women met the EPDS cut-off score of 12 at 3 and 6 months postpartum. Mother-infant relationship was well adapted for all 31 dyads at the end of the intervention. These results suggest that PCP is a promising intervention for treating perinatal depression and helping mothers engaging in parenting.

The BetaCage, an ultra-sensitive screener for surface contamination

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bunker, R.; Bowles, M. A.; Schnee, R. W.

Material screening for identifying low-energy electron emitters and alpha-decaying isotopes is now a prerequisite for rare-event searches (e.g., dark-matter direct detection and neutrinoless double-beta decay) for which surface radiocon-tamination has become an increasingly important background. The BetaCage, a gaseous neon time-projection chamber, is a proposed ultra-sensitive (and nondestructive) screener for alpha-and beta-emitting surface contaminants to which existing screening facilities are insufficiently sensitive. Sensitivity goals are 0.1 betas keV{sup −1} m{sup −2} day{sup −1} and 0.1 alphas m{sup −2} day{sup −1}, with the former limited by Compton scattering of photons in the screening samples and (thanks to tracking) the latter expectedmore » to be signal-limited; radioassays and simulations indicate backgrounds from detector materials and radon daughters should be subdominant. We report on details of the background simulations and detector design that provide the discrimination, shielding, and radiopurity necessary to reach our sensitivity goals for a chamber with a 95 × 95 cm{sup 2} sample area positioned below a 40 cm drift region and monitored by crisscrossed anode and cathode planes consisting of 151 wires each.« less

This study aimed to clarify the difference between the effective compounds of raw and processed Farfarae flos using a network pharmacology-integrated metabolomics strategy. First, metabolomics data were obtained by ultra high-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UHPLC-Q-TOF/MS). Then, metabolomics analysis was developed to screen for the influential compounds that were different between raw and processed Farfarae flos. Finally, a network pharmacology approach was applied to verify the activity of the screened compounds. As a result, 4 compounds (chlorogenic acid, caffeic acid, rutin and isoquercitrin) were successfully screened, identified, quantified and verified as the most influential effective compounds. They may synergistically inhibit the p38, JNK and ERK-mediated pathways, which would induce the inhibition of the expression of the IFA virus. The results revealed that the proposed network pharmacology-integrated metabolomics strategy was a powerful tool for discovering the effective compounds that were responsible for the difference between raw and processed Chinese herbs.

Sinogram restoration for ultra-low-dose x-ray multi-slice helical CT by nonparametric regression

2007-03-01

During the last decade, x-ray computed tomography (CT) has been applied to screen large asymptomatic smoking and nonsmoking populations for early lung cancer detection. Because a larger population will be involved in such screening exams, more and more attention has been paid to studying low-dose, even ultra-low-dose x-ray CT. However, reducing CT radiation exposure will increase noise level in the sinogram, thereby degrading the quality of reconstructed CT images as well as causing more streak artifacts near the apices of the lung. Thus, how to reduce the noise levels and streak artifacts in the low-dose CT images is becoming a meaningful topic. Since multi-slice helical CT has replaced conventional stop-and-shoot CT in many clinical applications, this research mainly focused on the noise reduction issue in multi-slice helical CT. The experiment data were provided by Siemens SOMATOM Sensation 16-Slice helical CT. It included both conventional CT data acquired under 120 kvp voltage and 119 mA current and ultra-low-dose CT data acquired under 120 kvp and 10 mA protocols. All other settings are the same as that of conventional CT. In this paper, a nonparametric smoothing method with thin plate smoothing splines and the roughness penalty was proposed to restore the ultra-low-dose CT raw data. Each projection frame was firstly divided into blocks, and then the 2D data in each block was fitted to a thin-plate smoothing splines' surface via minimizing a roughness-penalized least squares objective function. By doing so, the noise in each ultra-low-dose CT projection was reduced by leveraging the information contained not only within each individual projection profile, but also among nearby profiles. Finally the restored ultra-low-dose projection data were fed into standard filtered back projection (FBP) algorithm to reconstruct CT images. The rebuilt results as well as the comparison between proposed approach and traditional method were given in the results and discussions section, and showed effectiveness of proposed thin-plate based nonparametric regression method.

This study evaluated the effectiveness of a brief intervention (BI) for illicit drugs (cannabis, cocaine, amphetamine-type stimulants and opioids) linked to the World Health Organization (WHO) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). The ASSIST screens for problem or risky use of 10 psychoactive substances, producing a score for each substance that falls into either a low-, moderate- or high-risk category. Prospective, randomized controlled trial in which participants were either assigned to a 3-month waiting-list control condition or received brief motivational counselling lasting an average of 13.8 minutes for the drug receiving the highest ASSIST score. Primary health-care settings in four countries: Australia, Brazil, India and the United States. A total of 731 males and females scoring within the moderate-risk range of the ASSIST for cannabis, cocaine, amphetamine-type stimulants or opioids. ASSIST-specific substance involvement scores for cannabis, stimulants or opioids and ASSIST total illicit substance involvement score at baseline and 3 months post-randomization. Omnibus analyses indicated that those receiving the BI had significantly reduced scores for all measures, compared with control participants. Country-specific analyses showed that, with the exception of the site in the United States, BI participants had significantly lower ASSIST total illicit substance involvement scores at follow-up compared with the control participants. The sites in India and Brazil demonstrated a very strong brief intervention effect for cannabis scores (P < 0.005 for both sites), as did the sites in Australia (P < 0.005) and Brazil (P < 0.01) for stimulant scores and the Indian site for opioid scores (P < 0.01). The Alcohol, Smoking and Substance Involvement Screening Test-linked brief intervention aimed at reducing illicit substance use and related risks is effective, at least in the short term, and the effect generalizes across countries. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

On the maximum energy of shock-accelerated cosmic rays at ultra-relativistic shocks

NASA Astrophysics Data System (ADS)

Reville, B.; Bell, A. R.

2014-04-01

The maximum energy to which cosmic rays can be accelerated at weakly magnetised ultra-relativistic shocks is investigated. We demonstrate that for such shocks, in which the scattering of energetic particles is mediated exclusively by ion skin-depth scale structures, as might be expected for a Weibel-mediated shock, there is an intrinsic limit on the maximum energy to which particles can be accelerated. This maximum energy is determined from the requirement that particles must be isotropized in the downstream plasma frame before the mean field transports them far downstream, and falls considerably short of what is required to produce ultra-high-energy cosmic rays. To circumvent this limit, a highly disorganized field is required on larger scales. The growth of cosmic ray-induced instabilities on wavelengths much longer than the ion-plasma skin depth, both upstream and downstream of the shock, is considered. While these instabilities may play an important role in magnetic field amplification at relativistic shocks, on scales comparable to the gyroradius of the most energetic particles, the calculated growth rates have insufficient time to modify the scattering. Since strong modification is a necessary condition for particles in the downstream region to re-cross the shock, in the absence of an alternative scattering mechanism, these results imply that acceleration to higher energies is ruled out. If weakly magnetized ultra-relativistic shocks are disfavoured as high-energy particle accelerators in general, the search for potential sources of ultra-high-energy cosmic rays can be narrowed.

Our trauma division implemented a screening, brief intervention, and referral to treatment (SBIRT) program in 2009 and has maintained more than 92% screening rate for all inpatient admissions since inception. Brief interventions are proven to be more likely to effect and reinforce change if a follow-up contact is made with patients. This led to discussion regarding whether identified patients were more likely to follow up with our SBIRT wellness specialist using motivational interviewing or with our partners, exercise physiology, who use traditional interviewing techniques. We retrospectively reviewed more than 3,000 inpatient admissions in which screening for at-risk alcohol use were positive. Fifty-one percent of identified patients were referred for wellness specialist consultation with a follow-up rate of 52% compared with a follow-up rate of only 21% in the exercise physiology group. Motivational interviewing is more effective in encouraging at-risk alcohol users to participate in follow-up care.

Anodic oxide fabricated by anodizing has been widely used for nanostructural engineering, but the nanomorphology is limited to only two oxides: anodic barrier and porous oxides. Therefore, the discovery of an additional anodic oxide with a unique nanofeature would expand the applicability of anodizing. Here we demonstrate the fabrication of a third-generation anodic oxide, specifically, anodic alumina nanofibers, by anodizing in a new electrolyte, pyrophosphoric acid. Ultra-high density single nanometer-scale anodic alumina nanofibers (1010 nanofibers/cm2) consisting of an amorphous, pure aluminum oxide were successfully fabricated via pyrophosphoric acid anodizing. The nanomorphologies of the anodic nanofibers can be controlled by the electrochemical conditions. Anodic tungsten oxide nanofibers can also be fabricated by pyrophosphoric acid anodizing. The aluminum surface covered by the anodic alumina nanofibers exhibited ultra-fast superhydrophilic behavior, with a contact angle of less than 1°, within 1 second. Such ultra-narrow nanofibers can be used for various nanoapplications including catalysts, wettability control, and electronic devices.

Multiple sequence alignment (MSA) plays a key role in biological sequence analyses, especially in phylogenetic tree construction. Extreme increase in next-generation sequencing results in shortage of efficient ultra-large biological sequence alignment approaches for coping with different sequence types. Distributed and parallel computing represents a crucial technique for accelerating ultra-large (e.g. files more than 1 GB) sequence analyses. Based on HAlign and Spark distributed computing system, we implement a highly cost-efficient and time-efficient HAlign-II tool to address ultra-large multiple biological sequence alignment and phylogenetic tree construction. The experiments in the DNA and protein large scale data sets, which are more than 1GB files, showed that HAlign II could save time and space. It outperformed the current software tools. HAlign-II can efficiently carry out MSA and construct phylogenetic trees with ultra-large numbers of biological sequences. HAlign-II shows extremely high memory efficiency and scales well with increases in computing resource. THAlign-II provides a user-friendly web server based on our distributed computing infrastructure. HAlign-II with open-source codes and datasets was established at http://lab.malab.cn/soft/halign.

The Relationship dimension of the Family Environment Scale, which consists of the Cohesion, Expressiveness, and Conflict subscales, measures a person's perception of the quality of his or her family relationship functioning. This study investigates an adaptation of the Relationship dimension of the Family Environment Scale for Alaska Native youth. The authors tested the adapted measure, the Brief Family Relationship Scale, for psychometric properties and internal structure with 284 12- to 18-year-old predominately Yup'ik Eskimo Alaska Native adolescents from rural, remote communities. This non-Western cultural group is hypothesized to display higher levels of collectivism traditionally organized around an extended kinship family structure. Results demonstrate a subset of the adapted items function satisfactorily, a three-response alternative format provided meaningful information, and the subscale's underlying structure is best described through three distinct first-order factors, organized under one higher order factor. Convergent and discriminant validity of the Brief Family Relationship Scale was assessed through correlational analysis.

The successful development of an advanced powder metallurgy disk alloy, ME3, was initiated in the NASA High Speed Research/Enabling Propulsion Materials (HSR/EPM) Compressor/Turbine Disk program in cooperation with General Electric Engine Company and Pratt & Whitney Aircraft Engines. This alloy was designed using statistical screening and optimization of composition and processing variables to have extended durability at 1200 F in large disks. Disks of this alloy were produced at the conclusion of the program using a realistic scaled-up disk shape and processing to enable demonstration of these properties. The objective of the Ultra-Efficient Engine Technologies disk program was to assess the mechanical properties of these ME3 disks as functions of temperature in order to estimate the maximum temperature capabilities of this advanced alloy. These disks were sectioned, machined into specimens, and extensively tested. Additional sub-scale disks and blanks were processed and selectively tested to explore the effects of several processing variations on mechanical properties. Results indicate the baseline ME3 alloy and process can produce 1300 to 1350 F temperature capabilities, dependent on detailed disk and engine design property requirements.

There is considerable need for accurate suicide risk assessment for clinical, screening, and research purposes. This study applied the tripartite affect-behavior-cognition theory, the suicidal barometer model, classical test theory, and item response theory (IRT), to develop a brief self-report measure of suicide risk that is theoretically-grounded, reliable and valid. An initial survey (n = 359) employed an iterative process to an item pool, resulting in the six-item Suicidal Affect-Behavior-Cognition Scale (SABCS). Three additional studies tested the SABCS and a highly endorsed comparison measure. Studies included two online surveys (Ns = 1007, and 713), and one prospective clinical survey (n = 72; Time 2, n = 54). Factor analyses demonstrated SABCS construct validity through unidimensionality. Internal reliability was high (α = .86-.93, split-half = .90-.94)). The scale was predictive of future suicidal behaviors and suicidality (r = .68, .73, respectively), showed convergent validity, and the SABCS-4 demonstrated clinically relevant sensitivity to change. IRT analyses revealed the SABCS captured more information than the comparison measure, and better defined participants at low, moderate, and high risk. The SABCS is the first suicide risk measure to demonstrate no differential item functioning by sex, age, or ethnicity. In all comparisons, the SABCS showed incremental improvements over a highly endorsed scale through stronger predictive ability, reliability, and other properties. The SABCS is in the public domain, with this publication, and is suitable for clinical evaluations, public screening, and research. PMID:26030590

Mid-to-late adolescence is a critical period for initiation of alcohol and drug problems, which can be reduced by targeted brief motivational interventions. Web-based brief interventions have advantages in terms of acceptability and accessibility and have shown significant reductions of substance use among college students. However, the evidence is sparse among adolescents with at-risk use of alcohol and other drugs. This study evaluated the effectiveness of a targeted and fully automated Web-based brief motivational intervention with no face-to-face components on substance use among adolescents screened for at-risk substance use in four European countries. In an open-access, purely Web-based randomized controlled trial, a convenience sample of adolescents aged 16-18 years from Sweden, Germany, Belgium, and the Czech Republic was recruited using online and offline methods and screened online for at-risk substance use using the CRAFFT (Car, Relax, Alone, Forget, Friends, Trouble) screening instrument. Participants were randomized to a single session brief motivational intervention group or an assessment-only control group but not blinded. Primary outcome was differences in past month drinking measured by a self-reported AUDIT-C-based index score for drinking frequency, quantity, and frequency of binge drinking with measures collected online at baseline and after 3 months. Secondary outcomes were the AUDIT-C-based separate drinking indicators, illegal drug use, and polydrug use. All outcome analyses were conducted with and without Expectation Maximization (EM) imputation of missing follow-up data. In total, 2673 adolescents were screened and 1449 (54.2%) participants were randomized to the intervention or control group. After 3 months, 211 adolescents (14.5%) provided follow-up data. Compared to the control group, results from linear mixed models revealed significant reductions in self-reported past-month drinking in favor of the intervention group in both the non-imputed (P=.010) and the EM-imputed sample (P=.022). Secondary analyses revealed a significant effect on drinking frequency (P=.037) and frequency of binge drinking (P=.044) in the non-imputation-based analyses and drinking quantity (P=.021) when missing data were imputed. Analyses for illegal drug use and polydrug use revealed no significant differences between the study groups (Ps>.05). Although the study is limited by a large drop-out, significant between-group effects for alcohol use indicate that targeted brief motivational intervention in a fully automated Web-based format can be effective to reduce drinking and lessen existing substance use service barriers for at-risk drinking European adolescents.

The advent and development of ultra-intense tabletop laser systems has played a significant role in recent decades thanks to the wide number of applications and studies in which these systems were demonstrated to be appropriate. Among these, one of the main applications of ultra-intense radiation is generation of plasma by solid, liquid or gaseous targets. The by-product of x-radiation found many different applications such as spectroscopy, imaging, microlithography, microscopy, radiographies (in particular of biological samples), radiation-matter interaction, fundamental plasma parameter determination, astrophysics, inertial confinement fusion, high energy physics, quantum electrodynamics, and many others. In the following a brief description of our tabletop Nd:YAG/glass apparatus (facility of the Quantum Electronic and Plasma Laboratory of the University of Rome 'Tor Vergata'), together with x-ray conversion efficiency studies for different targets, are reported.

Screening for alcohol consumption in adolescents is widely justified in the health care field because of the particular vulnerability of this population, which starts drinking alcohol at a very early age and frequently consumes high levels of the same. Hospital emergency departments (ED) could be a good venue to manage early detection and carry out brief intervention (BI) programmes. The aim of this study was to identify perceived barriers for medical staff of three hospitals in Spain to successfully implement a protocol for alcohol detection and BI for minors in the ED. Exploratory qualitative analysis using focus groups with semi-structured, flexible and open-ended questions to explore beliefs, attitudes, and barriers perceived by professionals to screening alcohol consumption and implementing BI in adolescents attended at the ED. The main perceived barriers by health professionals were lack of time, work overload, mistrust, lack of validated and simple screening tools, lack of training/awareness and legal concerns about informed consent and confidentiality. Barriers to screening and intervention in ED are similar to those described previously. It is necessary to improve organization of time allocated for medical consultations, avoid limiting ED resources, motivate staff and provide appropriate training.

Family functioning plays a pivotal role in the adaptation to illness of both individuals and families, especially among elderly patients. The Brief Family Assessment Measure Third Edition (Brief FAM-III) is among the most frequently used self-report instruments that measures family functioning. However, no Danish translation or measure of its psychometric properties in a Danish population is available. The purpose of this study was to translate the Brief FAM-III into Danish and then evaluate its psychometric properties in elderly patients. The Brief FAM-III was translated into Danish using the forward-backward translation procedure and examined its psychometric properties in 60 elderly patients (aged over 65) consecutively admitted to an acute medical ward. Internal consistency reliability was assessed by Cronbach's alpha coefficients, and confirmatory factor analysis was used to examine the construct validity of the Brief FAM-III. Evaluation of the Danish version of the Brief FAM-III confirmed the three-factor structure (General Scale, Self-Rating Scale and Dyadic Relationships Scale) identified in the original instrument. However, goodness-of-fit indicators showed a relatively poor model fit. Cronbach's alpha for the total scales of Brief FAM-III was 0.94 suggesting good internal consistency. The Danish version of the Brief FAM-III demonstrated satisfactory validity and reliability to assess family functioning among acutely admitted elderly Danish patients. We suggest that it may also be useful for monitoring family functioning over time or determining the effects of therapeutic interventions in elderly medical patients; however, further testing is recommended. © 2017 Nordic College of Caring Science.

To assess and improve the accuracy of lay screeners compared with vision professionals in detecting visual impairment in secondary schoolchildren in rural China. After brief training, 32 teachers and a team of vision professionals independently measured vision in 1892 children in Xichang. The children also underwent vision measurement by health technicians in a concurrent government screening program. Of 32 teachers, 28 (87.5%) believed that teacher screening was worthwhile. Sensitivity (93.5%) and specificity (91.2%) of teachers detecting uncorrected presenting visual acuity of 20/40 or less were better than for presenting visual acuity (sensitivity, 85.2%; specificity, 84.8%). Failure of teachers to identify children owning but not wearing glasses and teacher bias toward better vision in children wearing glasses explain the worse results for initial vision. Wearing glasses was the student factor most strongly predictive of inaccurate teacher screening (P < .001). The sensitivity and specificity of the government screening program detecting low presenting visual acuity were 86.7% and 28.7%, respectively. Teacher vision screening after brief training can achieve accurate results in this setting, and there is support among teachers for screening. Screening of uncorrected rather than presenting visual acuity is recommended in settings with a high prevalence of corrected and uncorrected refractive error. Low specificity in the government program renders it ineffective.

We surveyed parents to ascertain interest in newborn genomic testing and determine whether these queries would provoke refusal of conventional state-mandated newborn screening. After a brief genetics orientation, parents rated their interest in receiving genomic testing for their healthy newborn on a 5-point Likert scale and answered questions about demographics and health history. We used logistic regression to explore factors associated with interest in genomic testing and tracked any subsequent rejection of newborn screening. We queried 514 parents within 48 hours after birth while still in hospital (mean age (SD) 32.7 (6.4) years, 65.2% female, 61.2% white, 79.3% married). Parents reported being not at all (6.4%), a little (10.9%), somewhat (36.6%), very (28.0%), or extremely (18.1%) interested in genomic testing for their newborns. None refused state-mandated newborn screening. Married participants and those with health concerns about their infant were less interested in newborn genomic testing (P = 0.012 and P = 0.030, respectively). Degree of interest for mothers and fathers was discordant (at least two categories different) for 24.4% of couples. Interest in newborn genomic testing was high among parents of healthy newborns, and the majority of couples had similar levels of interest. Surveying parents about genomic sequencing did not prompt rejection of newborn screening.Genet Med 17 6, 501-504.

Organic field effect transistor with ultra high amplification

2016-09-01

High-gain transistors are essential for the large-scale circuit integration, high-sensitivity sensors and signal amplification in sensing systems. Unfortunately, organic field-effect transistors show limited gain, usually of the order of tens, because of the large contact resistance and channel-length modulation. Here we show organic transistors fabricated on plastic foils enabling unipolar amplifiers with ultra-gain. The proposed approach is general and opens up new opportunities for ultra-large signal amplification in organic circuits and sensors.

Hospitalized patients have high rates of unhealthy substance use, which has important impacts on health both during and after hospitalization, but is infrequently identified in the absence of screening. The Substance Use Brief Screen (SUBS) was developed as a brief, self-administered instrument to identify use of tobacco, alcohol, illicit drugs, and non-medical use of prescription drugs, and was previously validated in primary care patients. This study assessed the diagnostic accuracy of the SUBS in comparison to longer screening instruments to identify unhealthy and high-risk alcohol and drug use in hospitalized current smokers. Participants were 439 patients, aged 18 and older, who were admitted to either two urban safety-net hospitals in New York City and enrolled in a smoking cessation trial. We measured the performance of the SUBS for identifying illicit drug and non-medical use of prescription drugs in comparison to a modified Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) and its performance for identifying excessive alcohol use in comparison to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C). At the standard cutoff (response other than 'never' indicates a positive screen), the SUBS had a sensitivity of 98% (95% CI 95-100%) and specificity of 61% (95% CI 55-67%) for unhealthy alcohol use, a sensitivity of 85% (95% CI 80-90%) and specificity of 75% (95% CI 78-87%) for illicit drug use, and a sensitivity of 73% (95% CI 61-83%) and specificity of 83% (95% CI 78-87%) for prescription drug non-medical use. For identifying high-risk use, a higher cutoff (response of '3 or more days' of use indicates a positive screen), the SUBS retained high sensitivity (77-90%), and specificity was 62-88%. The SUBS can be considered as an alternative to longer screening instruments, which may fit more easily into busy inpatient settings. Further study is needed to evaluate its validity using gold standard measures in hospitalized populations. Copyright © 2017 Elsevier Inc. All rights reserved.

Can screening and brief intervention lead to population-level reductions in alcohol-related harm?

PubMed Central

2012-01-01

A distinction is made between the clinical and public health justifications for screening and brief intervention (SBI) against hazardous and harmful alcohol consumption. Early claims for a public health benefit of SBI derived from research on general medical practitioners’ (GPs’) advice on smoking cessation, but these claims have not been realized, mainly because GPs have not incorporated SBI into their routine practice. A recent modeling exercise estimated that, if all GPs in England screened every patient at their next consultation, 96% of the general population would be screened over 10 years, with 70-79% of excessive drinkers receiving brief interventions (BI); assuming a 10% success rate, this would probably amount to a population-level effect of SBI. Thus, a public health benefit for SBI presupposes widespread screening; but recent government policy in England favors targeted versus universal screening, and in Scotland screening is based on new registrations and clinical presentation. A recent proposal for a national screening program was rejected by the UK National Health Service’s National Screening Committee because 1) there was no good evidence that SBI led to reductions in mortality or morbidity, and 2) a safe, simple, precise, and validated screening test was not available. Even in countries like Sweden and Finland, where expensive national programs to disseminate SBI have been implemented, only a minority of the population has been asked about drinking during health-care visits, and a minority of excessive drinkers has been advised to cut down. Although there has been research on the relationship between treatment for alcohol problems and population-level effects, there has been no such research for SBI, nor have there been experimental investigations of its relationship with population-level measures of alcohol-related harm. These are strongly recommended. In this article, conditions that would allow a population-level effect of SBI to occur are reviewed, including their political acceptability. It is tentatively concluded that widespread dissemination of SBI, without the implementation of alcohol control measures, might have indirect influences on levels of consumption and harm but would be unlikely on its own to result in public health benefits. However, if and when alcohol control measures were introduced, SBI would still have an important role in the battle against alcohol-related harm. PMID:23186309

The addiction treatment system only reaches a small number of individuals suffering from Internet-related disorders. Therefore, it is important to improve case detection for preventive measures and brief interventions. Existing screening instruments are often time-consuming and rarely validated using clinical criteria. The aim of this study is to develop an optimized short screening for problematic Internet use and Internet addiction (IA). A regression analysis was conducted in random subsamples of a merged sample (N = 3,040; N = 1,209) to examine the item performance of the Compulsive Internet Use Scale (CIUS). Based on the results, a short version of the CIUS was developed and compared with the original CIUS. A fully structured diagnostic interview, covering the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for the Internet gaming disorder with a broader focus on all Internet activities, was conducted. A five-item version of the short screening performed best across the samples. Comparing the area under the curve (AUC) of the receiver operating characteristic between the Short CIUS and the original test revealed no significant difference (AUC = 0.968; 0.977). A cutoff point of 7 turned out to perform best for case detection and yielded a sensitivity of 0.95 and a specificity of 0.87, Cronbach's alpha was 0.77. The analysis showed that the performance of the Short CIUS is just as good in detecting problematical Internet use and IA as the performance of the original CIUS. The Short CIUS provides an economical and valid instrument for the assessment of problematic Internet use and IA.

Unhealthy substance use in the USA results in significant mortality and morbidity. This study measured the effectiveness of paraprofessional-administered substance use screening, brief intervention, and referral to treatment (SBIRT) services on subsequent healthcare utilization and costs. The pre-post with comparison group study design used a population-based sample of Medicaid patients 18-64 years receiving healthcare services from 33 clinics in Wisconsin. Substance use screens were completed by 7367 Medicaid beneficiaries, who were compared to 6751 randomly selected treatment-as-usual Medicaid patients. Compared to unscreened patients, those screened changed their utilization over the 24-month follow-up period by 0.143 outpatient days per member per month (PMPM) (p < 0.001), -0.036 inpatient days PMPM (p < 0.05), -0.001 inpatient admissions PMPM (non-significant), and -0.004 emergency department days PMPM (non-significant). The best estimate of net annual savings is $391 per Medicaid adult beneficiary (2014 dollars). SBIRT was associated with significantly greater outpatient visits and significant reductions in inpatient days among working-age Medicaid beneficiaries in Wisconsin.

Evidence Does Not Support Clinical Screening of Literacy

PubMed Central

Wolf, Michael S.

2007-01-01

Limited health literacy is a significant risk factor for adverse health outcomes. Despite controversy, many health care professionals have called for routine clinical screening of patients’ literacy skills. Whereas brief literacy screening tools exist that with further evaluation could potentially be used to detect limited literacy in clinical settings, no screening program for limited literacy has been shown to be effective. Yet there is a noted potential for harm, in the form of shame and alienation, which might be induced through clinical screening. There is fair evidence to suggest that possible harm outweighs any current benefits; therefore, clinical screening for literacy should not be recommended at this time. PMID:17992564

Clinical utility of the impact of event scale: psychometrics in the general population.

Briere, J; Elliott, D M

1998-06-01

The Impact of Event Scale (IES; Horowitz, Wilner, & Alvarez, 1979), Trauma Symptom Inventory (TSI; Briere, 1995), Los Angeles Symptom Checklist (LASC; Foy, Sipprelle, Rueger, & Carroll, 1984), and Traumatic Events Survey (TES; Elliott, 1992) were administered to a sample of 505 participants from the general population. In this application of the IES, participants reported on "an upsetting event," as opposed to a specific stressor. The IES was found to be reliable and to have concurrent validity with respect to the TSI and LASC. IES scores varied as a function of race, but this relationship disappeared once race differences in exposure to potentially traumatic events (PTEs) were taken into account. Although the IES was predictive of PTEs, the traumatic stress scales of the TSI had more predictive and incremental validity than the IES. The current data suggest that an "upsetting event" version of the IES may be useful as a brief screen for nonarousal-related posttraumatic stress, but that its potential limitations should be taken into account. Normative data on this version of the IES are presented.

2015-08-01

This study examined the association between survey responses to health behaviors, personality/psychosocial factors, and self-reported sexually transmitted infections (STIs) to create a brief survey to identify youth at risk for contracting STIs. Participants included 200 racially diverse 14- to 18-year-old patients from a pediatric primary care clinic. Two sexual behavior variables and one peer norm variable were used to differentiate subgroups of individuals at risk of contracting a STI based on reported history of STIs using probability (decision tree) analyses. These items, as well as sexual orientation and having ever had oral sex, were used to create a brief sexual health screening (BSHS) survey. Each point increase in total BSHS score was associated with exponential growth in the percentage of sexually active adolescents reporting STIs. Findings suggest that the BSHS could serve as a useful tool for clinicians to quickly and accurately detect sexual risk among adolescent patients. © The Author(s) 2014.

Alcohol-related problems: emergency physicians' current practice and attitudes.

O'Rourke, Maria; Richardson, Lynne D; Wilets, Ilene; D'Onofrio, Gail

2006-04-01

To determine whether emergency physicians' (EPs) attitudes affect their support and practice of brief intervention in the Emergency Department (ED), EPs completed an anonymous survey. EPs were asked about their attitudes toward patients with alcohol problems, current ED screening, use of brief intervention, and barriers to use of brief intervention. Chi-square analysis was used and a step-wise regression model was constructed. Respondents reported a high prevalence of patients with alcohol-related problems: 18% in a typical shift. Eighty-one percent said it is important to advise patients to change behavior; half said using a brief intervention is important. Attending physicians had significantly less alcohol education than residents, but were significantly more likely to support the use of brief intervention. Support was not associated with gender, race, census, hours of education, or personal experience. EPs who felt that brief intervention was an integral part of their job were more likely to use it in their daily practice.

The purpose of this pilot study was to evaluate developmental neuropsychological profiles of 4- to 5-year-old children born after Preimplantation Genetic Diagnosis (PGD). Twenty-seven participants received a neurological examination and a battery of neuropsychological assessments including Wechsler Preschool & Primary Scale of Intelligence - Third Edition (WPPSI-III; cognitive development), Preschool Language Scale, Fourth Edition (PLS-4; language development), Wide Range Assessment of Visual Motor Abilities (visual motor abilities), Childhood Autism Rating Scales II (a screening test for autistic spectrum disorders), and the Miles ABC Test (ocular dominance). Parental questionnaires included the Behavior Rating Inventory of Executive Function Preschool Version (BRIEF-P; executive function), Child Behavior Checklist (CBCL) and the Carey Temperament Scales Behavioral Style Questionnaire (socioemotional development and temperament), and the Vineland Adaptive Behavior Scales, Interview Edition, Second Edition (general adaptive behavior). Subjects' tests results were compared to each test's norms. Children born after PGD demonstrated scores within the normal or above-normal ranges for all developmental outcomes (mean ± SD): WPPSI-III-VIQ 107.4 ± 14.4 (p = .013), PLS-4-Total 113.2 ± 12.4, p < .001), CBCL-Total 41.1 ± 8.6 (p < .001), BRIEF-P-Global Executive Composite 44.8 ± 9.5 (p = .009). Twelve (44%) of the PGD children had a significant difference between their VIQ and PIQ scores (compared to 27% in the general population). One subject was found to show possible signs of autistic spectrum disorder, although a family history of autism was noted. In conclusion, in this pilot study, children assessed at age 4-5 years and conceived after PGD displayed developmental neuropsychological outcomes within normal limits as compared to their chronologic peers. A larger study is needed to evaluate and follow the neuropsychological development of children born after PGD.

The 7-item Game Addiction Scale (GAS) is a used to screen for addictive game use. Both cross cross-linguistic validation and validation in French and German is needed in adult samples. The objective of the study is to assess the factorial structure of the French and German versions of the GAS among adults. Two samples of men from French (N = 3318) and German (N = 2665) language areas of Switzerland were assessed with the GAS, the Major Depression Inventory (MDI), the Brief Sensation Seeking Scale, and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ-50-cc). They were also assessed for cannabis and alcohol use. The internal consistency of the scale was satisfactory (Cronbach α = 0.85). A one-factor solution was found in both samples. Small and positive associations were found between GAS scores and the MDI, as well as the Neuroticism-Anxiety and Aggression-Hostility subscales of the ZKPQ-50-cc. A small negative association was found with the ZKPQ-50-cc Sociability subscale. The GAS, in its French and German versions, is appropriate for the assessment of game addiction among adults.

Development of a short form Social Interaction Anxiety (SIAS) and Social Phobia Scale (SPS) using nonparametric item response theory: the SIAS-6 and the SPS-6.

2012-03-01

Shortened forms of the Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS) were developed using nonparametric item response theory methods. Using data from socially phobic participants enrolled in 5 treatment trials (N = 456), 2 six-item scales (the SIAS-6 and the SPS-6) were developed. The validity of the scores on the SIAS-6 and the SPS-6 was then tested using traditional methods for their convergent validity in an independent clinical sample and a student sample, as well as for their sensitivity to change and diagnostic sensitivity in the clinical sample. The scores on the SIAS-6 and the SPS-6 correlated as well as the scores on the original SIAS and SPS, with scores on measures of related constructs, discriminated well between those with and without a diagnosis of social phobia, providing cutoffs for diagnosis and were as sensitive to measuring change associated with treatment as were the SIAS and SPS. Together, the SIAS-6 and the SPS-6 appear to be an efficient method of measuring symptoms of social phobia and provide a brief screening tool.

Background Alcohol use has important adverse effects on people living with HIV (PLWH). This study of patients with recognized unhealthy alcohol use estimated and compared rates of alcohol-related care received by PLWH and HIV− patients. Methods Outpatients from the Veterans Health Administration who had one or more positive screen(s) for unhealthy alcohol use (AUDIT-C≥5) documented in their medical records 10/2009–5/2013 were eligible. Primary and secondary outcomes were brief intervention documented ≤14 days after a positive alcohol screen, and a composite measure of any alcohol-related care (brief intervention, specialty addictions treatment or pharmacotherapy documented ≤365 days), respectively. Unadjusted and adjusted regression analyses compared alcohol-related care outcomes in PLWH and HIV− patients. Results The sample included 830,825 outpatients (3,514 PLWH), reflecting 1,172,606 positive screens (1–5 per patient). For PLWH, 57.0% (95% confidence interval 55.4–58.5%) of positive screens were followed by brief intervention, compared to 73.8% (73.7–73.9%) for HIV− patients [relative rate: 0.77 (0.75–0.79), p<0.001]. After adjustment, comparable proportions were 61.0% (59.3–62.6%) for PLWH and 73.7% (73.6–73.8%) for HIV− patients [adjusted RR=0.83 (0.80–0.85); p<0.001]. Secondary outcome results were similar: for PLWH and HIV− patients, 67.1% (65.7–68.6%) and 77.7% (95% CI 77.7–77.8%) of positive screens, respectively, were followed by any alcohol-related care after adjustment [adjusted RR=0.86 (0.85 – 0.88), p<0.001]. Conclusions In this large national sample of VA outpatients with unhealthy alcohol use, PLWH were less likely to receive alcohol-related care than HIV− patients. Special efforts may be needed to ensure alcohol-related care reaches PLWH. PMID:28324813

The performance of computer aided lung nodule detection (CAD) and computer aided nodule volumetry is compared between standard-dose (70-100 mAs) and ultra-low-dose CT images (5-10 mAs). A direct quantitative performance comparison was possible, since for each patient both an ultra-low-dose and a standard-dose CT scan were acquired within the same examination session. The data sets were recorded with a multi-slice CT scanner at the Charite university hospital Berlin with 1 mm slice thickness. Our computer aided nodule detection and segmentation algorithms were deployed on both ultra-low-dose and standard-dose CT data without any dose-specific fine-tuning or preprocessing. As a reference standard 292 nodules from 20 patients were visually identified, each nodule both in ultra-low-dose and standard-dose data sets. The CAD performance was analyzed by virtue of multiple FROC curves for different lower thresholds of the nodule diameter. For nodules with a volume-equivalent diameter equal or larger than 4 mm (149 nodules pairs), we observed a detection rate of 88% at a median false positive rate of 2 per patient in standard-dose images, and 86% detection rate in ultra-low-dose images, also at 2 FPs per patient. Including even smaller nodules equal or larger than 2 mm (272 nodules pairs), we observed a detection rate of 86% in standard-dose images, and 84% detection rate in ultra-low-dose images, both at a rate of 5 FPs per patient. Moreover, we observed a correlation of 94% between the volume-equivalent nodule diameter as automatically measured on ultra-low-dose versus on standard-dose images, indicating that ultra-low-dose CT is also feasible for growth-rate assessment in follow-up examinations. The comparable performance of lung nodule CAD in ultra-low-dose and standard-dose images is of particular interest with respect to lung cancer screening of asymptomatic patients.

In practical cardiology, a stethoscope based auscultation has been used to reveal the patient's clinical status. Recently, several hand-held echo devices are going on market and they are expected to play a role as "visible" auscultation instead of stethoscope. We have developed a portable and inexpensive echo device which can be used for screening of cardiac function. Two single element transducers were attached 180 degrees apart to a rotor with 14-mm diameter. The mechanical scanner, integrated circuits for transmitting and receiving ultrasonic signals and an A/D converter were encapsulated in a 150 x 40 mm probe weighing 200 g. The scan was started and the image was displayed on a Windows based personal computer (PC) as soon as the probe was connected to USB 2.0 port of the PC. The central frequency was available between 2.5 and 7.5 MHz, the image depth was 15 cm and the frame rate was 30/s. The estimated price of this ultra-portable ultrasound is about 3000 US dollars with software. For 69 cardiac patients with informed consent, image quality was compared with those obtained with basic range diagnostic echo machines. Left ventricular ejection fraction (EF) derived from normal M-mode image of standard machines (EFm) were compared with visual EF of the ultra-portable ultrasound device (EFv). The image quality was comparable to the basic range diagnostic echo machines although short axis view of aortic root was not clearly visualized because the probe was too large for intercostal approach. EFv agreed well with EFm. The ultra-portable ultrasound may provide useful information on screening and health care.

Perinatal intimate partner violence (IPV) is common and has significant negative health outcomes for mothers and infants. This study evaluated the effectiveness of an IPV intervention in reducing violence among abused women in perinatal home visiting programs. This assessor-blinded multisite randomized control trial of 239 women experiencing perinatal IPV was conducted from 2006 to 2012 in U.S. urban and rural settings. The Domestic Violence Enhanced Home Visitation Program (DOVE) intervention group (n = 124) received a structured abuse assessment and six home visitor-delivered empowerment sessions integrated into home visits. All participants were screened for IPV and referred appropriately. IPV was measured by the Conflicts Tactics Scale2 at baseline through 24 months postpartum. There was a significant decrease in IPV over time (F = 114.23; p < 0.001) from baseline to 1, 3, 6, 12, 18, and 24 months postpartum (all p < 0.001). Additional models examining change in IPV from baseline indicated a significant treatment effect (F = 6.45; p < 0.01). Women in the DOVE treatment group reported a larger mean decrease in IPV scores from baseline compared to women in the usual care group (mean decline 40.82 vs. 35.87). All models accounted for age and maternal depression as covariates. The DOVE intervention was effective in decreasing IPV and is brief, thereby facilitating its incorporation within well-woman and well-child care visits, as well as home visiting programs, while satisfying recommendations set forth in the Affordable Care Act for IPV screening and brief counseling.

Unhealthy alcohol use is a leading contributor to the global burden of disease, particularly among young people. Systematic reviews suggest efficacy of web-based alcohol screening and brief intervention and call for effectiveness trials in settings where it could be sustainably delivered. To evaluate a national web-based alcohol screening and brief intervention program. A multisite, double-blind, parallel-group, individually randomized trial was conducted at 7 New Zealand universities. In April and May of 2010, invitations containing hyperlinks to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) screening test were e-mailed to 14,991 students aged 17 to 24 years. Participants who screened positive (AUDIT-C score ≥4) were randomized to undergo screening alone or to 10 minutes of assessment and feedback (including comparisons with medical guidelines and peer norms) on alcohol expenditure, peak blood alcohol concentration, alcohol dependence, and access to help and information. A fully automated 5-month follow-up assessment was conducted that measured 6 primary outcomes: consumption per typical occasion, drinking frequency, volume of alcohol consumed, an academic problems score, and whether participants exceeded medical guidelines for acute harm (binge drinking) and chronic harm (heavy drinking). A Bonferroni-corrected significance threshold of .0083 was used to account for the 6 comparisons and a sensitivity analysis was used to assess possible attrition bias. Of 5135 students screened, 3422 scored 4 or greater and were randomized, and 83% were followed up. There was a significant effect on 1 of the 6 prespecified outcomes. Relative to control participants, those who received intervention consumed less alcohol per typical drinking occasion (median 4 drinks [interquartile range {IQR}, 2-8] vs 5 drinks [IQR 2-8]; rate ratio [RR], 0.93 [99.17% CI, 0.86-1.00]; P = .005) but not less often (RR, 0.95 [99.17% CI, 0.88-1.03]; P = .08) or less overall (RR, 0.95 [99.17% CI, 0.81-1.10]; P = .33). Academic problem scores were not lower (RR, 0.91 [99.17% CI, 0.76-1.08]; P = .14) and effects on the risks of binge drinking (odds ratio [OR], 0.84 [99.17% CI, 0.67-1.05]; P = .04) and heavy drinking (OR, 0.77 [99.17% CI, 0.56-1.05]; P = .03) were not significantly significant. In a sensitivity analysis accounting for attrition, the effect on alcohol per typical drinking occasion was no longer statistically significant. A national web-based alcohol screening and brief intervention program produced no significant reductions in the frequency or overall volume of drinking or academic problems. There remains a possibility of a small reduction in the amount of alcohol consumed per typical drinking occasion. anzctr.org.au Identifier: ACTRN12610000279022.

Alcohol is a major global threat to public health. Although the main burden of chronic alcohol-related disease is in adults, its foundations often lie in adolescence. Alcohol consumption and related harm increase steeply from the age of 12 until 20 years. Several trials focusing upon young people have reported significant positive effects of brief interventions on a range of alcohol consumption outcomes. A recent review of reviews also suggests that electronic brief interventions (eBIs) using internet and smartphone technologies may markedly reduce alcohol consumption compared with minimal or no intervention controls. Interventions that target non-drinking youth are known to delay the onset of drinking behaviours. Web based alcohol interventions for adolescents also demonstrate significantly greater reductions in consumption and harm among 'high-risk' drinkers; however changes in risk status at follow-up for non-drinkers or low-risk drinkers have not been assessed in controlled trials of brief alcohol interventions. The study design comprises two linked randomised controlled trials to evaluate the effectiveness and cost-effectiveness of two intervention strategies compared with screening alone. One trial will focus on high-risk adolescent drinkers attending Emergency Departments (Eds) and the other will focus on those identified as low-risk drinkers or abstinent from alcohol but attending the same ED. Our primary (null) hypothesis is similar for both trials: Personalised Feedback and Brief Advice (PFBA) and Personalised Feedback plus electronic Brief Intervention (eBI) are no more effective than screening alone in alcohol consumed at 12 months after randomisation as measured by the Time-Line Follow-Back 28-day version. Our secondary (null) hypothesis relating to economics states that PFBA and eBI are no more cost-effective than screening alone. In total 1,500 participants will be recruited into the trials, 750 high-risk drinkers and 750 low-risk drinkers or abstainers. Participants will be randomised with equal probability, stratified by centre, to either a screening only control group or one of the two interventions: single session of PFBA or eBI. All participants will be eligible to receive treatment as usual in addition to any trial intervention. Individual participants will be followed up at 6 and 12 months after randomisation. The protocol represents an ambitious innovative programme of work addressing alcohol use in the adolescent population. ISRCTN45300218. Registered 5th July 2014.

Since evaluation regarding the impact of mental illness related internalized stigma is scarce, there is a great need for psychometric instruments which could contribute to understanding its adverse effects among Greek patients with severe mental illness. The Brief Internalized Stigma of Mental Illness (ISMI) scale is one of the most widely used measures designed to assess the subjective experience of stigma related to mental illness. The present study aimed to investigate the psychometric properties of the Greek version of the Brief ISMI scale. In addition to presenting psychometric findings, we explored the relationship of the Greek version of the Brief ISMI subscales with indicators of self-esteem and quality of life. 272 outpatients (108 males, 164 females) meeting the DSM-IV TR criteria for severe mental disorder (schizophrenia, bipolar disorder, major depression) completed the Brief ISMI, the RSES and the WHOQOL-BREF scales. Patients reported age and educational level. A retest was conducted with 124 patients. The Chronbach's alpha coefficient was 0 0.83. The test-retest reliability coefficients varied from 0.81 to 0.91, indicating substantial agreement. The ICC was for the total score 0.83 and for the two factors, 0.69 and 0.77 respectively. Factor analysis provided strong evidence for a two factor model. Factors 1 and 2 were named respectively "how others view me" and "how I view myself". They were negatively correlated with both RSES and WHOQOL-BREF scales, as well as with educational level. Factor 2 was significantly associated with the type of diagnosis. The Greek version of the Brief ISMI scale can be used as a reliable and valid tool for assessing mental illness related internalized stigma among Greek patients with severe mental illness.

The specificity of screening for congenital adrenal hyperplasia by direct measurement of 17-hydroxyprogesterone in filter paper dried blood spot samples by immunoassay is low and has a high false-positive rate. In order to reduce the false-positive rate of this test, we developed a rapid, robust, specific confirmatory procedure in which cortisol, 4-androstene-3,17-dione and 17-hydroxyprogesterone were measured simultaneously by ultra-performance liquid chromatography-tandem mass spectrometry. After extraction, samples were analysed by ultra-performance liquid chromatography-tandem mass spectrometry and 17-hydroxyprogesterone was quantified accurately. Other steroids were determined using stable deuterated internal standards. In total, 25 patient blood spot samples and 92 control samples were analysed. The assay was linear for 17-hydroxyprogesterone, with a coefficient of determination >0.997 and imprecision ≤ 6.5%. An upper limit of normal for 17-hydroxyprogester-one of 4.45 nmol/L was established by analysing a cohort of samples from unaffected newborns. In addition, a cut-off of 3.5 for the peak areas ratio (17-hydroxyprogesterone+4-androstene-3,17-dione)/cortisol, allows confirmation of the affected steroidogenic enzyme. A high throughput method for the detection of steroids related to congenital adrenal hyperplasia has been developed, allowing the false-positive rate associated with screening for 17-hydroxyprogesterone by immunoassay to be determined.

In sub-Saharan Africa, large proportions of patients who are on antiretroviral therapy (ART) engage in excessive alcohol use, which may lead to adverse health consequences and may go undetected. Consequently, health care workers need brief screening tools to be able to routinely identify and manage excessive alcohol use among their patients. Various brief versions of the valid and reliable 10-item Alcohol Use Disorders Identification Test (AUDIT) (i.e., the AUDIT-C, AUDIT-3, AUDIT-QF, AUDIT-PC, AUDIT-4, and m-FAST) may potentially replace the full AUDIT in busy HIV care settings. This study aims to assess the utility of these six brief versions of the AUDIT relative to the full AUDIT for identifying excessive alcohol use among patients in HIV care settings in South Africa. Participants were 188 (95 women) patients from three ART clinics within district hospitals in the City of Tshwane Metropolitan Municipality who reported past-12-month alcohol use. Performance of each brief AUDIT measure for identifying excessive alcohol use was evaluated against that of the full AUDIT (with a cutoff score of ≥6 for women and ≥8 for men) as the gold standard. We used receiver-operating characteristic (ROC) analysis. Most brief AUDIT measures had an area under the receiver operating curve (AUROC) above .90 when compared with the full AUDIT (five of six for women and three of six for men). The AUDIT-PC, AUDIT-4, and m-FAST had the highest AUROCs, whereas the three brief measures comprising only consumption items had low specificities at the most optimal cutoff levels. Various brief versions of the AUDIT may be appropriate substitutes for the full AUDIT for screening for excessive alcohol use in HIV clinics in sub-Saharan Africa.

Variable screening via quantile partial correlation

PubMed Central

In quantile linear regression with ultra-high dimensional data, we propose an algorithm for screening all candidate variables and subsequently selecting relevant predictors. Specifically, we first employ quantile partial correlation for screening, and then we apply the extended Bayesian information criterion (EBIC) for best subset selection. Our proposed method can successfully select predictors when the variables are highly correlated, and it can also identify variables that make a contribution to the conditional quantiles but are marginally uncorrelated or weakly correlated with the response. Theoretical results show that the proposed algorithm can yield the sure screening set. By controlling the false selection rate, model selection consistency can be achieved theoretically. In practice, we proposed using EBIC for best subset selection so that the resulting model is screening consistent. Simulation studies demonstrate that the proposed algorithm performs well, and an empirical example is presented. PMID:28943683

Screening, brief intervention, and referral to treatment (SBIRT) is recommended as part of routine health care for adolescents as well as adults. In an effort to promote universal SBIRT, the Substance Abuse and Mental Health Services Administration awarded funding to residency programs to develop and implement SBIRT education and training. Our project focused on creating scientifically based, developmentally appropriate strategies and teaching materials for the adolescent age range. This paper describes curriculum development and implementation and presents evaluation data. Pediatric and child psychiatry residents were trained. The training consisted of 4 activities: (1) case-based teaching modules, (2) role-play of motivational interviewing and brief interventions, (3) mock interviews with trained adolescents, and (4) supervised "hands-on" screening and brief interventions. Main outcome measures included trainee satisfaction, and SBIRT knowledge, perceived self-efficacy, and self- and observer report of use of the SBIRT algorithm. Among 150 total participants completing the SBIRT training modules, nearly all (92.3%) were satisfied/very satisfied with the training modules. Knowledge accuracy immediately post training was high, but declined significantly by the end of the first residency year, with little change across subsequent years of residency. Confidence ratings also declined over time. Use of the SBIRT algorithm during the Adolescent Medicine rotation was high according to trainee self- and faculty observer report. We found evidence of training satisfaction, increased confidence in talking to adolescents about substance use, and widespread use of recommended practices immediately following training. Use of a highly structured algorithm to guide practice, and simple, highly structured brief interventions was a successful training approach, as residents self-reported accurate use of the SBIRT algorithm immediately after training. Knowledge and self-confidence declined over time. It is possible that "booster" sessions and ongoing opportunities to review materials could help residents retain knowledge and skills.

Mild cognitive impairment (MCI) often presages development of Alzheimer's disease (AD). We recently completed a cross-sectional study to test the hypothesis that a combination of a brief cognitive screening instrument (Mini-Cog) with a functional scale (Functional Activities Questionnaire; FAQ) would accurately identify individuals with MCI and undiagnosed dementia. The Mini-Cog consists of a clock drawing task and 3-item recall, and takes less than 5 minutes to administer. The FAQ is a 30-item questionnaire completed by an informant. In addition to the Mini-Cog and FAQ, a traditional cognitive test battery was administered, and two neurologists and a neuropsychologist determined a consensus diagnosis of Normal, MCI, or Dementia. A classification tree algorithm was used to pick optimal cutpoints, and, using these cutpoints, the combined Mini-Cog and FAQ (MC-FAQ) predicted the consensus diagnosis with an accuracy of 83% and a weighted kappa of 0.81. When the population was divided into Normal and Abnormal, the sensitivity, specificity and positive predictive value were 89%, 90%, and 95%, respectively. The MC-FAQ discriminates individuals with MCI from cognitively normal individuals and those with dementia, and its ease of administration makes it an attractive screening instrument to aid detection of cognitive impairment in the elderly.

Parenting behaviors, perceptions, and psychosocial risk: impacts on young children's development.

Glascoe, Frances Page; Leew, Shirley

2010-02-01

The goal of this study was to assess which parenting behaviors, perceptions, and risk factors were associated with optimal versus delayed development. A total of 382 families from the national Brigance Infant and Toddler Screens standardization and validation study participated. Data sources included parent questionnaires, child testing, and examiner observations of parent-child interactions. Parenting styles research was operationalized with the Brigance Parent-Child Interactions Scale, a brief measure of parenting behaviors and perceptions. Six positive parenting behaviors and perceptions predicted average to above-average development on the Brigance screens. Conversely, <2 positive parenting behaviors and negative perceptions of children indicated child performance nearly 2 SDs below the mean on Brigance screens. Psychosocial risk factors associated with fewer positive parenting behaviors and with negative perceptions included >3 children in the home, multiple moves, limited English, and parental depression. A dearth of positive parenting behaviors plus negative perceptions of children, with or without psychosocial risk factors, negatively affect child development, which is apparent as early as 6 months of age. The older the child is, the greater the performance gaps are. Language development is particularly at risk when parenting is problematic. Findings underscore the importance of early development promotion with parents, focusing on their talking, playing, and reading with children, and the need for interventions regarding psychosocial risk factors.

Galaxias enanas: las voces de la mayoría

Cellone, S. A.

More than twenty years after photographic surveys of nearby clusters of galaxies revealed that low-luminosity, or ``dwarf'', galaxies (M_B ≳ -18 mag) are the numerically dominant population, research on these objects has been boosted by new instrumental and theoretical developments. Among several breakthroughs that have re-shaped our knowledge abut dwarf galaxies, we should point out: the detection of underlying spiral structure, disks/bars in dwarf ``elliptical'' galaxies; the possible evolutionary relation between (some?) dwarf ellipticals and spiral galaxies; the discoveries of ultra-compact and ultra-faint dwarfs; the universality of the color-luminosity relation extending along ˜ 10 mag. A brief review on these subjects is presented, with emphasis on early-type dwarfs and their possible evolutionary relations with other galaxy types. I will particularly address the controversy about which are the objects that extend the E sequence down to the lowest luminosities (if such objects really exist). FULL TEXT IN SPANISH

This report documents the construction, wind tunnel testing, and data analysis of a 1/5 scale ultra-light wing section. Wind tunnel testing provided accurate and meaningful lift, drag, and pitching moment data. This data was processed and graphically presented as follows: C(sub L) vs. gamma; C(sub D) vs. gamma; C(sub M) vs. gamma; and C(sub L) vs. C(sub D). The wing fabric flexure was found to be significant and its possible effects on aerodynamic data was discussed. The fabric flexure is directly related to wing angle of attack and airspeed. Different wing section shapes created by fabric flexure are presented with explanations of the types of pressures that act upon the wing surface. This report provides conclusive aerodynamic data for ultra-light wings.

Kalibjian, Ralph

1981-01-01

An electronic framing camera tube features focal plane image dissection and synchronized restoration of the dissected electron line images to form two-dimensional framed images. Ultra-fast framing is performed by first streaking a two-dimensional electron image across a narrow slit, thereby dissecting the two-dimensional electron image into sequential electron line images. The dissected electron line images are then restored into a framed image by a restorer deflector operated synchronously with the dissector deflector. The number of framed images on the tube's viewing screen is equal to the number of dissecting slits in the tube. The distinguishing features of this ultra-fast framing camera tube are the focal plane dissecting slits, and the synchronously-operated restorer deflector which restores the dissected electron line images into a two-dimensional framed image. The framing camera tube can produce image frames having high spatial resolution of optical events in the sub-100 picosecond range.

1-Adamantylamine a simple urine marker for screening for third generation adamantyl-type synthetic cannabinoids by ultra-performance liquid chromatography tandem mass spectrometry.

Ford, Loretta T; Berg, Jonathan D

2016-11-01

Background Synthetic cannabinoids (NOIDS) are novel psychotropic drugs (NPS) currently freely sold in the United Kingdom as 'research chemicals'. Detection of NOIDS use is not available in current routine methods. Here we describe a marker which helps determine which patients have used these substances. Methods In a test case, ultra-performance liquid chromatography mass spectrometry (UPLC-Tof) was used to screen the legal high Herbal Haze II, the contents of hand-rolled cigarettes and five patient samples for NOIDS and their metabolites. Results Analysis of legal high Herbal Haze II and cigarettes identified the third generation adamantyl-type NOIDS N-(1-adamantyl)-1-pentyl-1H-indazole-3-carboxamide (AKB-48), 5F-AKB-48 and N-adamantyl-1-fluoropentylindole-3-carboxamide (STS-135). Out of 18 potential metabolites, 1-adamantylamine (C 10 H 17 N) was detected in all five urine samples. This adamantyl-type NOID marker was incorporated into our routine LC-MS/MS urine screen. Out of 14,436 random urine samples screened over eight months, 296 (2.05%) tested positive for the adamantyl-type NOID marker. Conclusion We have discovered a urine marker for identifying patients smoking legal high products containing the third generation adamantyl-type NOIDS such as AKB-48 and its fluoropentyl analogue 5F-AKB-48, which are among the most popular NOIDS currently available in legal high products sold in UK. This marker can be incorporated into routine LC-MS/MS drug screening alongside classic drugs of abuse. Positive detection rates for this new legal high marker are greater than for established classic drugs that are routinely screened such as amphetamine. This work highlights the need for a flexible toxicology screening service capable of adapting to changes in drug use such as the growing popularity of legal highs/NPS.

The pediatric emergency department (ED) is a critical location for the identification of children and adolescents at risk for suicide. Screening instruments that can be easily incorporated into clinical practice in EDs to identify and intervene with patients at increased suicide risk is a promising suicide prevention strategy and patient safety objective. This study is a retrospective review of the implementation of a brief suicide screen for pediatric psychiatric ED patients as standard of care. The Ask Suicide Screening Questions (ASQ) was implemented in an urban pediatric ED for patients with psychiatric presenting complaints. Nursing compliance rates, identification of at-risk patients, and sensitivity for repeated ED visits were evaluated using medical records from 970 patients. The ASQ was implemented with a compliance rate of 79 %. Fifty-three percent of the patients who screened positive (237/448) did not present to the ED with suicide-related complaints. These identified patients were more likely to be male, African American, and have externalizing behavior diagnoses. The ASQ demonstrated a sensitivity of 93 % and specificity of 43 % to predict return ED visits with suicide-related presenting complaints within 6 months of the index visit. Brief suicide screening instruments can be incorporated into standard of care in pediatric ED settings. Such screens can identify patients who do not directly report suicide-related presenting complaints at triage and who may be at particular risk for future suicidal behavior. Results have the potential to inform suicide prevention strategies in pediatric EDs.

This study evaluated the psychometric characteristics of the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1996) in 280 individuals who screened positive for posttraumatic stress disorder (PTSD). The SNAP validity, trait, temperament, and personality disorder (PD) scales were compared with scales on the Brief Form of the Multidimensional Personality Questionnaire (Patrick, Curtin, & Tellegen, 2002). In a subsample of 86 veterans, the SNAP PD, trait, and temperament scales were also evaluated in comparison to the International Personality Disorder Exam (IPDE; Loranger, 1999), a semi-structured diagnostic interview. Results revealed that the SNAP scales have good convergent validity, as evidenced by their pattern of associations with related measures of personality and PD. However evidence for their discriminant validity in relationship to other measures of personality and PD was more mixed and test scores on the SNAP trait and temperament scales left much unexplained variance in IPDE-assessed PDs. The diagnostic scoring of the SNAP PD scales greatly inflated prevalence estimates of PDs relative to the IPDE and showed poor agreement with the IPDE. In contrast, the dimensional SNAP scores yielded far stronger associations with continuous scores on the IPDE. The SNAP scales also largely evidenced expected patterns of association with a measure of PTSD severity. Overall, findings support the use of this measure in this population and contribute to our conceptualization of the association between temperament, PTSD, and Axis II psychopathology. PMID:21767029

US Food and Drug Administration (FDA) warnings recommend monitoring negative symptoms associated with the initiation of antidepressant medications as these symptoms may interfere with full recovery and pose safety concerns. There is currently no brief, reliable rating instrument for assessing treatment-emergent, negative symptoms. We evaluated the psychometric properties of 2 versions of the newly developed 17-item Concise Associated Symptom Tracking (CAST) scale, the CAST Clinician Rating (CAST-C) and CAST Self-Rated (CAST-SR), which are brief instruments designed to measure the 5 relevant associated symptom domains (irritability, anxiety, mania, insomnia, and panic). The study enrolled 265 outpatients with major depressive disorder (MDD), from July 2007 through February 2008, into an 8-week, open-label trial with a selective serotonin reuptake inhibitor. Diagnosis of MDD was determined by the Psychiatric Diagnostic Screening questionnaire and an MDD checklist based on DSM-IV-TR criteria. Suicidality (suicidal ideation with associated behaviors) is 1 of 9 symptoms of MDD (depressed mood, loss of interest, appetite or weight change, sleep disturbance, reduced concentration or indecisiveness, fatigue or decreased energy, psychomotor agitation or retardation, feelings of worthlessness or excessive guilt). Psychometric evaluations were conducted on both versions of the CAST. Cronbach α was .80 (CAST-C) and .81 (CAST-SR). Factor analysis identified 5 factors for each scale: (1) irritability, (2) anxiety, (3) mania, (4) insomnia, and (5) panic. When the item that cross-loaded on 2 factors was eliminated, the 16-item solution had a better goodness of fit (CAST-C: 0.90 vs 0.87; CAST-SR: 0.88 vs 0.84). Cronbach α for the 16-item versions was .77 (CAST-C) and .78 (CAST-SR). The 5 associated CAST symptom domains correlated well with other standard measures of these domains. The 16-item CAST-C and CAST-SR demonstrated excellent psychometric properties. These are potentially useful measures for monitoring treatment-emergent negative symptoms associated with antidepressants, as recommended by the FDA.

The purpose of this study was to develop and evaluate the initial reliability, validity and classification accuracy of a new brief screen for adolescent problem gambling. The three-item Brief Adolescent Gambling Screen (BAGS) was derived from the nine-item Gambling Problem Severity Subscale (GPSS) of the Canadian Adolescent Gambling Inventory (CAGI) using a secondary analysis of existing CAGI data. The sample of 105 adolescents included 49 females and 56 males from Canada who completed the CAGI, a self-administered measure of DSM-IV diagnostic criteria for Pathological Gambling, and a clinician-administered diagnostic interview including the DSM-IV diagnostic criteria for Pathological Gambling (both of which were adapted to yield DSM-5 Gambling Disorder diagnosis). A stepwise multivariate discriminant function analysis selected three GPSS items as the best predictors of a diagnosis of Gambling Disorder. The BAGS demonstrated satisfactory estimates of reliability, validity and classification accuracy and was equivalent to the nine-item GPSS of the CAGI and the BAGS was more accurate than the SOGS-RA. The BAGS estimates of classification accuracy include hit rate = 0.95, sensitivity = 0.88, specificity = 0.98, false positive rate = 0.02, and false negative rate = 0.12. Since these classification estimates are preliminary, derived from a relatively small sample size, and based upon the same sample from which the items were selected, it will be important to cross-validate the BAGS with larger and more diverse samples. The BAGS should be evaluated for use as a screening tool in both clinical and school settings as well as epidemiological surveys. PMID:29312064

The objective of this study was to develop an effective strategy for screening and identifying mycotoxins in herbal medicine (HM). Here, Imperatae Rhizoma, a commonly used Chinese herb, was selected as a model HM. A crude drug contaminated with fungi was analyzed by comparing with uncontaminated ones. Ultra-performance LC coupled to tandem quadrupole TOF-MS (UPLC-Q-TOF-MS) with collision energy function was applied to analyze different samples from Imperatae Rhizoma. Then, MarkerLynx(TM) software was employed to screen the excess components in analytes, compared with control samples, and those selected markers were likely to be the metabolites of fungi. Furthermore, each of the accurate masses of the markers obtained from MarkerLynx(TM) was then searched in a mycotoxins/fungal metabolites database established in advance. The molecular formulas with relative mass error between the measured and theoretical mass within 5 ppm were chosen and then applied to MassFragment(TM) analysis for further confirmation of their structures. With the use of this approach, five mycotoxins that have never been reported in HM were identified in contaminated Imperatae Rhizoma. The results demonstrate the potential of UPLC-Q-TOF-MS coupled with the MarkerLynx(TM) software and MassFragment(TM) tool as an efficient and convenient method to screen and identify mycotoxins in herbal materials and aid in the quality control of HM. © 2013 WILEY-VCH Verlag GmbH & Co.

To compare the results of non-mydriatic ultra-wide field imaging system, mydriatic slit-lamp lens (Volk +90 D) and mydriatic Goldmann three-mirror contact lens examinations in screening fundus lesions among patients after cataract surgery. Non-mydriatic images were obtained with an Optomap panoramic 200Tx (Optomap 200Tx) 3d after surgery and graded by a blinded ophthalmologist. A mydriatic slit-lamp lens examination was performed by another blinded retinal specialist on the same day. A third blinded retinal specialist examined patients two weeks after surgery using a Goldmann three-mirror contact lens. In total, 160 patients (184 eyes) were examined, and 66, 69, and 75 cases of retinal lesion(s) were identified using the Optomap 200Tx, slit-lamp lens, and Goldmann three-mirror contact lens, respectively. In 13 cases, fundus changes were sight-threatening. The results obtained by Optomap 200Tx examination and by mydriatic slit-lamp lens examination have good consistency (P=0.375, Kappa=0.942). The mydriatic Goldmann three-mirror lens examination revealed more fundus lesions but are consistent with Optomap 200Tx (P=0.004, Kappa=0.897) and mydriatic slit-lamp lens examination (P=0.031, Kappa=0.932). Early post-operative fundus screening in cataract patients is extremely important and necessary to prevent further vision loss. Wide-field imaging is a feasible and convenient tool for fundus examination that can be used as a primary screening method among patients after cataract surgery.

Low background rare event searches in underground laboratories seeking observation of direct dark matter interactions or neutrino-less double beta decay have the potential to profoundly advance our understanding of the physical universe. Successful results from these experiments depend critically on construction from extremely radiologically clean materials and accurate knowledge of subsequent low levels of expected background. The experiments must conduct comprehensive screening campaigns to reduce radioactivity from detector components, and these measurements also inform detailed characterisation and quantification of background sources and their impact, necessary to assign statistical significance to any potential discovery. To provide requisite sensitivity for material screeningmore » and characterisation in the UK to support our rare event search activities, we have re-developed our infrastructure to add ultra-low background capability across a range of complementary techniques that collectively allow complete radioactivity measurements. Ultra-low background HPGe and BEGe detectors have been installed at the Boulby Underground Laboratory, itself undergoing substantial facility re-furbishment, to provide high sensitivity gamma spectroscopy in particular for measuring the uranium and thorium decay series products. Dedicated low-activity mass spectrometry instrumentation has been developed at UCL for part per trillion level contaminant identification to complement underground screening with direct U and Th measurements, and meet throughput demands. Finally, radon emanation screening at UCL measures radon background inaccessible to gamma or mass spectrometry techniques. With this new capability the UK is delivering half of the radioactivity screening for the LZ dark matter search experiment.« less

Shapes displayed with durations in the microsecond range do not obey Bloch's law of temporal summation

PubMed Central

Greene, Ernest; Ogden, R. Todd

2013-01-01

Shape patterns were displayed with simultaneous brief flashes from a light-emitting diode array. Flash durations in the microsecond range and luminous intensities were adjusted to vary the degree of successful shape recognition. Four experiments were conducted to test whether Bloch's law would apply in this task. Bloch's law holds that for very brief flashes the perceptual threshold is determined by the total number of photons being delivered, i.e., there is reciprocity of intensity and duration. The present results did not find that effectiveness of flashes was based on the total quantity of photons, as predicted by Bloch's law. Additionally, the evidence points to a visual mechanism that has ultra-high temporal precision that either registers the rate of photon flux or the duration of flashes. PMID:24349700

This study aimed to determine the prevalence of HIV neurocognitive impairment in HIV-infected men who have sex with men aged 18-50 years, using a simple battery of screening tests in routine clinical appointments. Those with suspected abnormalities were referred on for further assessment. The cohort was also followed up over time to look at evolving changes. HIV-infected participants were recruited at three clinical sites in London during from routine clinical visits. They could be clinician or self-referred and did not need to be symptomatic. They completed questionnaires on anxiety, depression, and memory. They were then screened using the Brief Neurocognitive Screen (BNCS) and International HIV Dementia Scale (IHDS). Two hundred and five HIV-infected subjects were recruited. Of these, 59 patients were excluded as having a mood disorder and two patients were excluded due to insufficient data, leaving 144 patients for analysis. One hundred and twenty-four (86.1%) had a normal composite z score (within 1 SD of mean) calculated for their scores on the three component tests of the BNCS. Twenty (13.9%) had an abnormal z score, of which seven (35%) were symptomatic and 13 (65%) asymptomatic. Current employment and previous educational level were significantly associated with BNCS scores. Of those referred onwards for diagnostic testing, only one participant was found to have impairment likely related to HIV infection. We were able to easily screen for mood disorders and cognitive impairment in routine clinical practice. We identified a high level of depression and anxiety in our cohort. Using simple screening tests in clinic and an onward referral process for further testing, we were not able to identify neurocognitive impairment in this cohort at levels consistent with published data.

The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is a screening instrument to detect substance use in primary care (PC). To screen for illicit substances (excluding tobacco and alcohol), the ASSIST consists of 8-57 questions and requires complicated scoring. To improve the efficiency of screening of drug misuse in PC, this study constructed and validated a two-item screen for drug use from the ASSIST. Guided by previous reviews, the ASSIST was revised. Patients were recruited in VA primary care clinics (N=1283). Half of the sample was used to develop the ASSIST-Drug; the other half was used to validate it. The Mini International Neuropsychiatric Interview (MINI) and the Inventory of Drug Use Consequences were the criterion measures. A brief, two-item ASSIST-Drug was constructed. Based on the development sample, the ASSIST-Drug was 94.1% sensitive and 89.6% specific for drug use disorders. Based on the validation sample, it was 95.4% sensitive and 87.8% specific. The ASSIST-Drug also had comparable sensitivity and specificity to identify drug use negative consequences, as well as for diverse subgroups of patients in terms of gender, age, race/ethnicity, marital status, educational levels, and post traumatic stress disorder status. The ASSIST-Drug may be a useful screening tool for PC settings. It is reliable, brief, and easy to remember, administer and score. It is sensitive and specific for drug use disorders and drug use negative consequences, and the predictive properties are consistent across subgroup of patients. Published by Elsevier Ireland Ltd.

Social and role functioning are compromised for the majority of individuals at ultra-high risk of psychosis, and it is important to identify factors that contribute to this functional decline. This study aimed to investigate social cognitive abilities, which have previously been linked to functioning in schizophrenia, as potential factors that impact social, role and global functioning in ultra-high risk patients. A total of 30 ultra-high risk patients were recruited from an established at-risk clinical service in Melbourne, Australia, and completed a battery of social cognitive, neurocognitive, clinical and functioning measures. We examined the relationships between all four core domains of social cognition (emotion recognition, theory of mind, social perception and attributional style), neurocognitive, clinical and demographic variables with three measures of functioning (the Global Functioning Social and Role scales and the Social and Occupational Functioning Assessment Scale) using correlational and multiple regression analyses. Performance on a visual theory of mind task (visual jokes task) was significantly correlated with both concurrent role ( r = 0.425, p = 0.019) and global functioning ( r = 0.540, p = 0.002). In multivariate analyses, it also accounted for unique variance in global, but not role functioning after adjusting for negative symptoms and stress. Social functioning was not associated with performance on any of the social cognition tasks. Among specific social cognitive abilities, only a test of theory of mind was associated with functioning in our ultra-high risk sample. Further longitudinal research is needed to examine the impact of social cognitive deficits on long-term functional outcome in the ultra-high risk group. Identifying social cognitive abilities that significantly impact functioning is important to inform the development of targeted intervention programmes for ultra-high risk individuals.

Diabetic peripheral neuropathy is very common in the diabetic population. Early screening for foot pathology is of the utmost importance. The Michigan Neuropathy Screening Instrument (MNSI) is an easy, brief, and noninvasive screening tool. The aim of this study was to validate the semantics and characteristics of both sections of the Portuguese translation of the MNSI for Portuguese diabetic patients. A cross-sectional study was performed on 87 type 1 and 2 diabetic patients at our outpatient endocrinology department. The final sample was composed of 76 patients. Nerve conduction studies were requested, but only a subsample of 42 patients agreed to participate in them. The scale was internally consistent (Cronbach's alpha > 0.70 in section A, or a clinical history questionnaire and a physical examination [section B]), and the scores of both sections were positively correlated (r = 0.70; P < 0.001). With regard to stability, MNSI scores between test/retest showed high stability (intraclass correlation coefficient = 0.91). The receiver-operating characteristic (ROC) demonstrated its validity, with ROC curve values for section A, section B, and sections A + B of 0.913, 0.798, and 0.906 respectively. Considering a cut off of ≥ 3 in section A and of ≥ 2 in section B, we obtained a sensitivity of 100% and 86%; a specificity of 64% and 61%; a positive predictive value of 80% and 73%; and a negative predictive value of 100% and 79%, respectively. The Portuguese MNSI is a reliable and valid tool for screening diabetic neuropathy. © 2016 World Institute of Pain.

Brief, psychometrically robust questionnaires assessing work-related psychosocial stressors are lacking. The purpose of the study is to evaluate the psychometric properties of a brief new questionnaire for assessing sources of work-related psychosocial stress. Managers, blue- and white-collar workers (n= 628 at measurement point one, n=459 at measurement point two), sampled from an online panel of a German marketing research institute. We either developed or identified appropriate items from existing questionnaires for ten scales, which are conceptually based in work stress models and reflected either work-related demands or resources. Factorial structure was evaluated by confirmatory factor analyses (CFA). Scale reliability was assessed by Cronbach's Alpha, and test-retest; correlations with work-related efforts demonstrated convergent and discriminant validity for the demand and resource scales, respectively. Scale correlations with health indicators tested criterion validity. All scales had satisfactory reliability (Cronbach's Alpha: 0.74-0.93, retest reliabilities: 0.66-0.81). CFA supported the anticipated factorial structure. Significant correlations between job-related efforts and demand scales (mean r=0.44) and non-significant correlations with the resource scales (mean r=0.07) suggested good convergent and discriminant validity, respectively. Scale correlations with health indicators demonstrated good criterion validity. The WHC appears to be a brief, psychometrically robust instrument for assessing work-related psychosocial stressors.

The identification of HIV-positive patients who exhibit criteria for Posttraumatic Stress Disorder (PTSD) and related trauma symptomatology is of clinical importance in the maintenance of their overall wellbeing. This study assessed the sensitivity and specificity of the 17-item Posttraumatic Stress Diagnostic Scale (PDS), a self-report instrument, in the detection of HIV-related PTSD. An adapted version of the PTSD module of the Composite International Diagnostic Interview (CIDI) served as the gold standard. 85 HIV-positive patients diagnosed with HIV within the year preceding data collection were recruited by means of convenience sampling from three HIV clinics within primary health care facilities in the Boland region of South Africa. A significant association was found between the 17-item PDS and the adapted PTSD module of the CIDI. A ROC curve analysis indicated that the 17-item PDS correctly discriminated between PTSD caseness and non-caseness 74.9% of the time. Moreover, a PDS cut-off point of > or = 15 yielded adequate sensitivity (68%) and 1-specificity (65%). The 17-item PDS demonstrated a PPV of 76.0% and a NPV of 56.7%. The 17-item PDS can be used as a brief screening measure for the detection of HIV-related PTSD among HIV-positive patients in South Africa.

Ultra-light weight and ultra-thin membrane inflatable antenna concepts are fast evolving to become the state-of-the-art antenna concepts for deep-space applications. NASA Langley Research Center has been involved in the structural dynamics research on antenna structures. One of the goals of the research is to develop structural analysis methodology for prediction of the static and dynamic response characteristics of the inflatable antenna concepts. This research is focused on the computational studies to use nonlinear large deformation finite element analysis to characterize the ultra-thin membrane responses of the antennas. Recently, structural analyses have been performed on a few parabolic reflector antennas of varying size and shape, which are referred in the paper as 0.3 meters subscale, 2 meters half-scale, and 4 meters full-scale antenna. The various aspects studied included nonlinear analysis methodology and solution techniques, ways to speed convergence in iterative methods, the sensitivities of responses with respect to structural loads, such as inflation pressure, gravity, and pretension loads in the ground and in-space conditions, and the ultra-thin membrane wrinkling characteristics. Several such intrinsic aspects studied have provided valuable insight into evaluation of structural characteristics of such antennas. While analyzing these structural characteristics, a quick study was also made to assess the applicability of dynamics scaling of the half-scale antenna. This paper presents the details of the nonlinear structural analysis results, and discusses the insight gained from the studies on the various intrinsic aspects of the analysis methodology. The predicted reflector surface characteristics of the three inflatable ultra-thin membrane parabolic reflector antenna concepts are presented as easily observable displacement fringe patterns with associated maximum values, and normal mode shapes and associated frequencies. Wrinkling patterns are presented to show how surface wrinkle progress with increasing tension loads. Antenna reflector surface accuracies were found to be very much dependent on the type and size of the antenna, the reflector surface curvature, reflector membrane supports in terms of spacing of catenaries, as well as the amount of applied load.

Screening, brief intervention, and referral to treatment for military spouses experiencing alcohol and substance use disorders: a literature review.

PubMed

Ahmadi, Halima; Green, Scott L

2011-06-01

This paper provides an overview of alcohol and substance use issues in military spouses, and explore how the screening, brief intervention, and referral to treatment (SBIRT) model may enable health care providers to identify individuals at risk for developing substance use related disorders. The information presented is based on a broad literature scan relating to the characteristics of the military lifestyle, health infrastructure, screening and intervention processes, and the uses of SBIRT in military and civilian settings. Current literature suggests that military spouses, and families, tend to be at different points in their life course than civilian families of similar ages. Marrying earlier and having children sooner coupled with military lifestyle stressors place them at increased risk for developing adverse coping mechanisms, particularly during deployment. SBIRT has been recognized as an effective method among civilian patients although there is limited research on the efficacy of SBIRT for military spouses at risk of or experiencing substance use problems.

HIV-associated sensory neuropathy (HIV-SN) is a common, and frequently painful complication of HIV, but factors that determine the presence of pain are unresolved. We investigated: (i) if psychological factors associated with painful (n = 125) versus non-painful HIV-SN (n = 72), and (ii) if pain and psychological factors affected quality of life (QoL). We assessed anxiety and depression using the Hopkins Symptoms Checklist-25. Pain catastrophizing and QoL were assessed using the Pain Catastrophizing Scale and Euroqol-5D, respectively. Presence of neuropathy was detected using the Brief Neuropathy Screening Tool, and pain was characterised using the Wisconsin Brief Pain Questionnaire. Overall, there was a high burden of pain, depression and anxiety in the cohort. None of the psychological variables associated with having painful HIV-SN. Greater depressive symptoms and presence of pain were independently associated with lower QoL. In those participants with painful HIV-SN, greater depressive symptom scores were associated with increased pain intensity. In conclusion, in a cohort with high background levels of psychological dysfunction, psychological factors do not predict the presence of pain, but both depression and presence of pain are associated with poor quality of life.

Dimensional assessments are planned to be included as supplements to categorical diagnoses in DSM-V. The aim of this study was to examine the unidimensionality, reliability, validity, and clinical sensitivity of brief self-rated scales for specific anxiety disorders in an unselected German sample of consecutive attendees to a psychological clinic. These scales use a common template to assess core constructs of fear and anxiety. Dimensional scales for social anxiety disorder, specific phobia, agoraphobia, panic disorder, and generalized anxiety disorder were administered along with established scales to 102 adults seeking treatment for mental health problems at a German university outpatient clinic for psychotherapy. The computer-assisted clinical version of the Munich-Composite International Diagnostic Interview was used to assess mental disorders according to DSM-IV criteria. Dimensionality and scale reliability were examined using confirmatory factor analyses. Convergent and discriminant validity were examined by testing differences in the size of correlations between each dimensional anxiety scale and each of the previously validated scales. Each dimensional scale's ability to correctly differentiate between individuals with versus without an anxiety diagnosis was examined via the area under the curve. Analyses revealed unidimensionality for each scale, high reliability, and convergent and discriminant validity. Classification performance was good to excellent for all scales except for specific phobia. The application of the dimensional anxiety scales may be an effective way to screen for specific anxiety disorders and to supplement categorical diagnoses in DSM-V, although further evaluation and refinement of the scales (particularly the specific phobia scale) is needed. © 2012 Wiley Periodicals, Inc.

A Randomized Study of the Use of Screening, Brief Intervention, and Referral to Treatment (SBIRT) for Drug and Alcohol Use with Jail Inmates

PubMed Central

Prendergast, Michael L.; McCollister, Kathryn; Warda, Umme

2017-01-01

Background Screening, brief intervention, and referral to treatment (SBIRT) is an evidence-based practice that has been shown to reduce alcohol and drug use in healthcare, educational, and other settings, but research on the effectiveness of SBIRT with populations involved in the criminal justice system is limited. These populations have high rates of substance use but have limited access to interventions. Methods The study randomized 732 jail inmates from a large urban jail to the SBIRT intervention or to the control group. Using the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), the intervention assessed the risk level for drug and alcohol misuse by inmates and provided those who were at low or medium risk with a brief intervention in jail and referred those at high risk to community treatment following release, including the opportunity to participate in a brief treatment (eight sessions) protocol. Using interview and records data from a 12-month follow-up, analyses compared the two groups with respect to the primary study outcomes of reductions in drug and alcohol use and the secondary outcomes of participation in treatment, rearrest, reduction in HIV risk behaviors, and quality of life. In addition, the costs of delivering the SBIRT intervention were calculated. Results When baseline differences were controlled, the groups did not differ at follow-up on any of the primary or secondary outcomes. Conclusions Future research should develop and evaluate SBIRT models that are specifically adapted to the characteristics and needs of the jail population. Until more favorable results emerge, attempts to use SBIRT with jail inmates should be implemented with caution, if at all. PMID:28132701

Under-reporting of drug use in the perinatal period is well-documented, and significantly limits the reach of proactive intervention approaches. The Wayne Indirect Drug Use Screener (WIDUS) focuses on correlates of drug use rather than use itself. This trial tested a computer-delivered, brief intervention designed for use with indirect screen-positive cases, seeking to motivate reductions in drug use without presuming its presence. Randomized clinical trial with 500 WIDUS-positive postpartum women recruited between August 14, 2012 and November 19, 2014. Participants were randomly assigned to either a time control condition or a single-session, tailored, indirect brief intervention. The primary outcome was days of drug use over the 6-month follow-up period; secondary outcomes included urine and hair analyses results at 3- and 6-month follow-up. All outcomes were measured by blinded evaluators. Of the 500 participants (252 intervention and 248 control), 36.1% of participants acknowledged drug use in the 3 months prior to pregnancy, but 89% tested positive at the 6-month follow-up. Participants rated the intervention as easy to use (4.9/5) and helpful (4.4/5). Analyses revealed no between-group differences in drug use (52% in the intervention group, vs. 53% among controls; OR 1.03). Exploratory analyses also showed that intervention effects were not moderated by baseline severity, WIDUS score, or readiness to change. The present trial showed no evidence of efficacy for an indirect, single-session, computer-delivered, brief intervention designed as a complement to indirect screening. More direct approaches that still do not presume active drug use may be possible and appropriate. Copyright © 2018 Elsevier B.V. All rights reserved.

Risk assessments are widely used, but their ability to predict outcomes in opioid use disorder (OUD) treatment remains unclear. Therefore, the aim was to investigate if addiction-specific brief risk screening is effective in identifying high mortality risk groups and if subsequent clinical actions following risk assessment impacts on mortality levels. Opioid use disorder (OUD) patients were identified in the South London and Maudsley Case Register. Deaths were identified through database linkage to the national mortality dataset. Cox and competing-risk regression were used to model associations between brief risk assessment domains and all-cause and overdose mortality in 4488 OUD patients, with up-to 6-year follow-up time where 227 deaths were registered. Data were stratified by admission to general mental health services. All-cause mortality was significantly associated with unsafe injecting (HR 1.53, 95% CI 1.10-2.11) and clinically appraised likelihood of accidental overdose (HR 1.48, 95% CI 1.00-2.19). Overdose-mortality was significantly associated with unsafe injecting (SHR 2.52, 95% CI 1.11-5.70) and clinically appraised suicidality (SHR 2.89, 95% CI 1.38-6.03). Suicidality was associated with a twofold increase in mortality risk among OUD patients who were not admitted to mental health services within 2 months of their risk assessment (HR 2.03, 95% CI 1.67-3.24). Diagnosis-specific brief risk screening can identify OUD patient subgroups at increased risk of all-cause and overdose mortality. OUD patients, where suicidality is evident, who are not admitted into services are particularly vulnerable. Copyright © 2016 The Author(s). Published by Elsevier Ireland Ltd.. All rights reserved.

Self-harm is a major risk factor for completed suicide. To determine the efficacy of a brief psychological intervention - culturally adapted manual-assisted problem-solving training (C-MAP) - delivered following an episode of self-harm compared with treatment as usual (TAU). The study was a randomised controlled assessor-masked clinical trial (trial registration: ClinicalTrials.gov NCT01308151). All patients admitted after an episode of self-harm during the previous 7 days to the participating medical units of three university hospitals in Karachi, Pakistan, were included in the study. A total of 250 patients were screened and 221 were randomly allocated to C-MAP plus treatment as usual (TAU) or to TAU alone. All patients were assessed at baseline, at 3 months (end of intervention) and at 6 months after baseline. The primary outcome measure was reduction in suicidal ideation at 3 months. The secondary outcome measures included hopelessness, depression, coping resources and healthcare utilisation. A total of 108 patients were randomised to the C-MAP group and 113 to the TAU group. Patients in the C-MAP group showed statistically significant improvement on the Beck Scale for Suicide Ideation and Beck Hopelessness Inventory, which was sustained at 3 months after the completion of C-MAP. There was also a significant reduction in symptoms of depression compared with patients receiving TAU. The positive outcomes of this brief psychological intervention in patients attempting self-harm are promising and suggest that C-MAP may have a role in suicide prevention.

Many screening tools for detecting cognitive decline require in-person assessment, which is often not cost-effective or feasible for those with physical limitations. The Modified Telephone Interview for Cognitive Status has been used for screening dementia, but little is known about its usefulness in detecting amnestic mild cognitive impairment. Community-dwelling participants (mean age=74.9, mean education = 16.1 years) were administered the Modified Telephone Interview for Cognitive Status during initial screening and subsequently given a multidomain neuropsychological battery. Participants were classified by consensus panel as cognitively normal older adult (noMCI, N=54) or amnestic mild cognitive impairment (N=17) based on neuropsychological performance and Clinical Dementia Rating Scale interview, but independent of Modified Telephone Interview for Cognitive Status score. There was a significant difference between groups in Modified Telephone Interview for Cognitive Status score (t=8.04, P<.01, noMCI range 32-43, mean [SD]=37.4 [2.5], amnestic mild cognitive impairment range 25-37, mean [SD]=31.2 [3.5]). Discriminant function analysis revealed that TICS-M alone correctly classified 85.9% of participants into their respective diagnostic classification (sensitivity=82.4%, specificity=87.0%). Receiver operating characteristics analysis resulted in cutoff score of 34 that optimized sensitivity and specificity of amnestic mild cognitive impairment classification. The Modified Telephone Interview for Cognitive Status is a brief, cost-effective screening measure for identifying those with and without amnestic mild cognitive impairment.

The evidence base to assess the efficacy and effectiveness of alcohol brief interventions (ABI) is weakened by variation in the outcomes measured and by inconsistent reporting. The 'Outcome Reporting in Brief Intervention Trials: Alcohol' (ORBITAL) project aims to develop a core outcome set (COS) and reporting guidance for its use in future trials of ABI in a range of settings. An international Special Interest Group was convened through INEBRIA (International Network on Brief Interventions for Alcohol and Other Drugs) to inform the development of a COS for trials of ABI. ORBITAL will incorporate a systematic review to map outcomes used in efficacy and effectiveness trials of ABI and their measurement properties, using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. This will support a multi-round Delphi study to prioritise outcomes. Delphi panellists will be drawn from a range of settings and stakeholder groups, and the Delphi study will also be used to determine if a single COS is relevant for all settings. A consensus meeting with key stakeholder representation will determine the final COS and associated guidance for its use in trials of ABI. ORBITAL will develop a COS for alcohol screening and brief intervention trials, with outcomes stratified into domains and guidance on outcome measurement instruments. The standardisation of ABI outcomes and their measurement will support the ongoing development of ABI studies and a systematic synthesis of emerging research findings. We will track the extent to which the COS delivers on this promise through an exploration of the use of the guidance in the decade following COS publication.

We identified coping behaviors during regular health check-ups and examined whether they were related to physical and mental health. We assessed coping strategies with the Brief COPE scale in 201 people who underwent a regular health check-up in a clinic. We found several significant relationships between coping and physical/psychological conditions presented in health check-up: Humor and systolic blood pressure, Substance use and high-density lipoprotein cholesterol, Venting and low-density lipoprotein cholesterol, Self-blame and depression, and Behavioral disengagement and sleep disorder. By evaluating coping strategies and screening depression as part of a regular health check-up, General practitioner can provide psychological intervention such as cognitive behavioral therapy which may improve both mental and physical health of the people.
