In an influential 2002 paper, Farrington and colleagues argued that to understand ‘causes’ of delinquency, within-individual analyses of longitudinal data are required (compared to the vast majority of analyses that have focused on between-individual differences). The current paper aimed to complete similar analyses to those conducted by Farrington and colleagues by focusing on the developmental correlates and risk factors for antisocial behaviour and by comparing within-individual and between-individual predictors of antisocial behaviour using data from the youngest Victorian cohort of the International Youth Development Study, a state-wide representative sample of 927 students from Victoria, Australia. Data analysed in the current paper are from participants in Year 6 (age 11–12 years) in 2003 to Year 11 (age 16–17 years) in 2008 (N = 791; 85% retention) with data collected almost annually. Participants completed a self-report survey of risk and protective factors and antisocial behaviour. Complete data were available for 563 participants. The results of this study showed all but one of the forward- (family conflict) and backward-lagged (low attachment to parents) correlations were statistically significant for the within-individual analyses compared with all analyses being statistically significant for the between-individual analyses. In general, between-individual correlations were greater in magnitude than within-individual correlations. Given that forward-lagged within-individual correlations provide more salient measures of causes of delinquency, it is important that longitudinal studies with multi-wave data analyse and report their data using both between-individual and within-individual correlations to inform current prevention and early intervention programs seeking to reduce rates of antisocial behaviour.

Wymore, Lucas; Reeve, Robert E.; Chaput, Christopher D.

2012-01-01

Purpose: To established an association between shoulder pain and the stroke specialization among NCAA men swimmers. Materials and Methods: All members of the top 25 NCAA men's swim teams were invited to complete the survey. Eleven teams with a total of 187 participants completed the study survey. The teams were mailed surveys that included multiple choice questions regarding their primary stroke and their incidence of shoulder pain. Additionally, the survey included questions about risk factors including distance trained, type of equipment, weight training, and stretching. Results: The analysis showed that there was no significant difference in the rates of shoulder pain among the four strokes and individual medley specialists. The other risk factors did not show a significant correlation with shoulder pain. Conclusions: This study found no significant correlation between stroke specialty and shoulder pain in male collegiate swimmers. Level of Evidence: Level 3. Clinical Relevance: Descriptive epidemiology study. PMID:23204760

Correlation between performance in physics and prior mathematics knowledge

NASA Astrophysics Data System (ADS)

Hudson, H. T.; Rottmann, Ray M.

The final grade of 1403 students enrolled in the first semester of the introductory, pre-professional physics course has been correlated with performance on a precourse diagnostic test of mathematical skills. The students were from a total of eight different sections taught by six separate instructors over a three year time span. The student population has been separated into two groups, those who completed the course (913 students) and those who dropped (490 students). The drops were assigned a projected final gradebased on performance up to date of withdrawal. The Pearson product-moment correlation for students who completed the course is 0.418 and correlation for the drops is 0.232. Both correlations are significant at the p < 0.001 level. This study suggests that prior mathematical ability is a primary influence on performance in the course, and has a secondary influence on the tendency to drop out of the course.

We evaluated feasibility and benefit of implementing structured learning in a robotics program. Furthermore, we assessed validity of a proficiency assessment tool for stepwise graduation. Teaching cases included robotic radical prostatectomy and partial nephrectomy. Procedure steps were categorized: basic, intermediate, and advanced. An assessment tool ["proficiency score" (PS)] was developed to evaluate ability to safely and autonomously complete a step. Graduation required a passing PS (PS ≥ 3) on three consecutive attempts. PS and validated global evaluative assessment of robotic skills (GEARS) were evaluated for completed steps. Linear regression was utilized to determine postgraduate year/PS relationship (construct validity). Spearman's rank correlation coefficient measured correlation between PS and GEARS evaluations (concurrent validity). Intraclass correlation (ICC) evaluated PS agreement between evaluator classes. Twenty-one robotic trainees participated within the pilot program, completing a median of 14 (2-69) cases each. Twenty-three study evaluators scored 14 (1-60) cases. Over 4 months, 229/294 (78 %) cases were designated "teaching" cases. Residents completed 91 % of possible evaluations; faculty completed 78 %. Verbal and quantitative feedback received by trainees increased significantly (p = 0.002, p < 0.001, respectively). Average PS increased with PGY (post-graduate year) for basic and intermediate steps (regression slopes: 0.402 (p < 0.0001), 0.323 (p < 0.0001), respectively) (construct validation). Overall, PS correlated highly with GEARS (ρ = 0.81, p < 0.0001) (concurrent validity). ICC was 0.77 (95 % CI 0.61-0.88) for resident evaluations. Structured learning can be implemented in an academic robotic program with high levels of trainee and evaluator participation, encouraging both quantitative and verbal feedback. A proficiency assessment tool developed for step-specific proficiency has construct and concurrent validity.

Patient-reported outcomes (PRO) instruments are a vital source of data for evaluating the efficacy of medical treatments. Historically, outcomes instruments have been designed, validated, and implemented as paper-based questionnaires. The collection of paper-based outcomes information may result in patients becoming fatigued as they respond to redundant questions. This problem is exacerbated when multiple PRO measures are provided to a single patient. In addition, the management and analysis of data collected in paper format involves labor-intensive processes to score and render the data analyzable. Computer-based outcomes systems have the potential to mitigate these problems by reformatting multiple outcomes tools into a single, user-friendly tool.The study aimed to determine whether the electronic outcomes system presented produces results comparable with the test-retest correlations reported for the corresponding orthopedic paper-based outcomes instruments.The study is designed as a crossover study based on consecutive orthopaedic patients arriving at one of two designated orthopedic knee clinics.Patients were assigned to complete either a paper or a computer-administered questionnaire based on a similar set of questions (Knee injury and Osteoarthritis Outcome Score, International Knee Documentation Committee form, 36-Item Short Form survey, version 1, Lysholm Knee Scoring Scale). Each patient completed the same surveys using the other instrument, so that all patients had completed both paper and electronic versions. Correlations between the results from the two modes were studied and compared with test-retest data from the original validation studies.The original validation studies established test-retest reliability by computing correlation coefficients for two administrations of the paper instrument. Those correlation coefficients were all in the range of 0.7 to 0.9, which was deemed satisfactory. The present study computed correlation coefficients between the paper and electronic modes of administration. These correlation coefficients demonstrated similar results with an overall value of 0.86.On the basis of the correlation coefficients, the electronic application of commonly used knee outcome scores compare variably to the traditional paper variants with a high rate of test-retest correlation. This equivalence supports the use of the condensed electronic outcomes system and validates comparison of scores between electronic and paper modes.

Although many studies have examined executive functions and facial emotion recognition in people with schizophrenia, few of them focused on the correlation between them. Furthermore, their relationship in the siblings of patients also remains unclear. The aim of the present study is to examine the correlation between executive functions and facial emotion recognition in patients with first-episode schizophrenia and their siblings. Thirty patients with first-episode schizophrenia, their twenty-six siblings, and thirty healthy controls were enrolled. They completed facial emotion recognition tasks using the Ekman Standard Faces Database, and executive functioning was measured by Wisconsin Card Sorting Test (WCST). Hierarchical regression analysis was applied to assess the correlation between executive functions and facial emotion recognition. Our study found that in siblings, the accuracy in recognizing low degree 'disgust' emotion was negatively correlated with the total correct rate in WCST (r = -0.614, p = 0.023), but was positively correlated with the total error in WCST (r = 0.623, p = 0.020); the accuracy in recognizing 'neutral' emotion was positively correlated with the total error rate in WCST (r = 0.683, p = 0.014) while negatively correlated with the total correct rate in WCST (r = -0.677, p = 0.017). People with schizophrenia showed an impairment in facial emotion recognition when identifying moderate 'happy' facial emotion, the accuracy of which was significantly correlated with the number of completed categories of WCST (R(2) = 0.432, P < .05). There were no correlations between executive functions and facial emotion recognition in the healthy control group. Our study demonstrated that facial emotion recognition impairment correlated with executive function impairment in people with schizophrenia and their unaffected siblings but not in healthy controls.

Sensory processing patterns may be associated with children's preferences for different activities; however, knowledge about how different sensory processing patterns may relate to children's participation in leisure activities is scarce. This study investigated in what leisure activities children with extreme sensory processing patterns participate and if relationships exist between children's sensory processing patterns and their leisure preferences and participation patterns. This correlational study analyzed data from children's Sensory Profiles and reported play and leisure preferences. All 91 children in the sample completed the Children's Assessment for Participation and Enjoyment (CAPE) and the Preferences for Activities of Children (PAC). Parents of children ages 6 to 10 years completed the Sensory Profile, and children ages 11 to 14 years completed the Adolescent/Adult Sensory Profile. Children with different sensory processing patterns preferred both similar and distinct leisure activities. Low-registration quadrant summary z scores negatively correlated with CAPE overall diversity scores (rs=-.23, p=.03), sensitivity quadrant summary z scores negatively correlated with preferences for social activities (rs=-.23, p=.03) and preferences for skill-based activities (rs=-.22, p=.04), and avoiding quadrant summary z scores negatively correlated with preferences for social activities (rs=-.26, p=.01). Children's sensory preferences are related to leisure preferences and participation. © CAOT 2015.

Retrospective review. To determine the correlation of Patient-Reported Outcomes Measurement Information System (PROMIS) physical function with Neck Disability Index (NDI) and Modified Japanese Orthopedic Association (mJOA) scores in the surgical cervical myelopathy patient population. Outcome measures such as NDI and mJOA are essential for analyzing treatments for cervical myelopathy. Administrative burdens impose limits on completion of these measures. The PROMIS group developed an outcome measure to improve reporting of patient symptoms and function and to reduce administrative burden. Despite early success, NDI and mJOA have not been compared with PROMIS in patients with cervical myelopathy. This study determines the correlation of NDI and mJOA with PROMIS in surgical patients with cervical myelopathy. A total of 60 patients with cervical myelopathy undergoing surgery were included. PROMIS, NDI, and mJOA were collected preoperatively, and in the first 6 months postoperatively. Correlations between NDI, mJOA, and PROMIS were quantified using Pearson correlation coefficients. Students t tests were used to test significance. All 60 (100%) of patients completed preoperative questionnaires. Fifty-five (92%) of patients completed initial follow-up questionnaires within the first 6 months. PROMIS physical function and NDI demonstrated a strong negative correlation at baseline and in initial follow-up (R = -0.69, -0.76). PROMIS and mJOA demonstrated a strong positive correlation at baseline and in initial follow-up (R = 0.61, 0.72). PROMIS physical function has a strong negative correlation with NDI and a strong positive correlation with mJOA at baseline and in the early postoperative course in patients undergoing surgery for cervical myelopathy. Surgeons may factor these outcomes into the delivery and interpretation of patient-reported outcome measures in this population. Use of PROMIS may improve completion of outcome measures in the office and reduce administrative burden while still providing reliable outcomes data. 3.

Abstract Background Testing aerobic fitness in youth is important because of expected relationships with health. Objective The purpose of the study was to estimate the validity and reliability of the Shuttle Ride Test in youth who have spina bifida and use a wheelchair for mobility and sport. Design Ths study is a validity and reliability study. Methods The Shuttle Ride Test, Graded Wheelchair Propulsion Test, and skill-related fitness tests were administered to 33 participants for the validity study (age = 14.5 ± 3.1 y) and to 28 participants for the reliability study (age = 14.7 ± 3.3 y). Results No significant differences were found between the Graded Wheelchair Propulsion Test and the Shuttle Ride Test for most cardiorespiratory responses. Correlations between the Graded Wheelchair Propulsion Test and the Shuttle Ride Test were moderate to high (r = .55–.97). The variance in peak oxygen uptake (VO2peak) could be predicted for 77% of the participants by height, number of shuttles completed, and weight, with large prediction intervals. High correlations were found between number of shuttles completed and skill-related fitness tests (CI = .73 to −.92). Intraclass correlation coefficients were high (.77–.98), with a smallest detectable change of 1.5 for number of shuttles completed and with coefficients of variation of 6.2% and 6.4% for absolute VO2peak and relative VO2peak, respectively. Conclusions When measuring VO2peak directly by using a mobile gas analysis system, the Shuttle Ride Test is highly valid for testing VO2peak in youth who have spina bifida and use a wheelchair for mobility and sport. The outcome measure of number of shuttles represents aerobic fitness and is also highly correlated with both anaerobic performance and agility. It is not possible to predict VO2peak accurately by using the number of shuttles completed. Moreover, the Shuttle Ride Test is highly reliable in youth with spina bifida, with a good smallest detectable change for the number of shuttles completed. PMID:29029556

We examined the associations among physical activity, neurological disability, and cardiorespiratory fitness in two studies of individuals with multiple sclerosis (MS). Study 1 included 25 women with relapsing-remitting MS (RRMS) who undertook an incremental exercise test for measuring peak oxygen (VO₂(peak) ) consumption, wore an accelerometer during a 7-day period, and completed the Godin Leisure-Time Exercise Questionnaire (GLTEQ). Study 2 was a follow-up of Study 1 and included 24 women with RRMS who completed the self-reported Expanded Disability Status Scale (EDSS), undertook an incremental exercise test, wore an accelerometer during a 7-day period, and completed the GLTEQ. Study 1 indicated that VO₂(peak) was significantly correlated with accelerometer counts (pr = 0.69) and GLTEQ scores (pr = 0.63) even after controlling for age and MS duration. Study 2 indicated that VO₂(peak) was significantly correlated with accelerometer counts (pr = 0.50), GLTEQ scores (pr = 0.59), and EDSS scores (pr = -0.43) even after controlling for age and MS duration; there was a moderate partial correlation between accelerometer counts and EDSS scores (pr = -0.43). Multiple linear regression analysis indicated that both accelerometer counts (β = 0.32) and EDSS scores (β = -0.40) had statistically significant associations with VO₂(peak). The findings indicate that physical inactivity and neurological disability might represent independent risk factors for reduced levels of cardiorespiratory fitness in this population. © 2010 John Wiley & Sons A/S.

Abstract To formulate therapy goals, we aimed to define the relationship between fecal calprotectin and health-related quality of life in inflammatory bowel diseases (IBDs). This retrospective single-center cross-sectional study included ambulatory IBD patients who had completed standardized questionnaires comprising items of health-related quality of life (Short Inflammatory Bowel Disease Questionnaire) and clinical disease activity scores, and who had provided stool samples for calprotectin determination within 30 days of questionnaire completion. Correlation analyses were performed between the indicated parameters. Post hoc analysis was conducted, taking into account only data from patients with fecal calprotectin concentrations measured within 3 days of questionnaire completion. One hundred ninety-seven patients with Crohn disease and 111 patients with ulcerative colitis were enrolled in the study. Lower fecal calprotectin concentrations were associated with better health-related quality of life. The correlations were weak, but stronger if only fecal calprotectin concentrations measured within 3 days of questionnaire completion were included (results for 3 days; Crohn disease: n = 86, rS = −0.419, P < 0.001; ulcerative colitis: n = 43, rS = −0.432, P = 0.004). In Crohn disease, a significant correlation between fecal calprotectin concentration and health-related quality of life was found in patients with colonic involvement (n = 59, rS = −0.470, P < 0.001), but not in patients with purely ileal disease (n = 27, rS = −0.268, P = 0.18). Correlations between fecal calprotectin concentrations and clinical disease activity were also only weak to moderate. Owing to its moderate correlation with fecal calprotectin concentrations in IBD patients with colonic involvement, health-related quality of life should be used in combination with other markers for IBD management. This is even more important in isolated ileal Crohn disease, where no significant correlation between fecal calprotectin concentration and health-related quality of life was found. Especially for use in research studies, care should be taken to keep the time between clinical evaluation of IBD patients and the determination of fecal calprotectin concentrations as short as possible.

The aim of this study was to adapt the Australian Quality of Life in Childhood Epilepsy Questionnaire (QOLCE) and determine its psychometric properties in a North American population. Participants were North American families with children diagnosed with epilepsy. Parents were asked to complete the American QOLCE (USQOLCE) and the Child Health Questionnaire (CHQ). Seventy-one families completed the USQOLCE. The internal consistency reliability of the subscales was good. USQOLCE subscales correlated highly with theoretically similar subscales contained in the CHQ. Theoretically dissimilar subscales on the two instruments did not correlate as well. USQOLCE correlated significantly with a parental rating of seizure severity and an independent measure of degree of postoperative seizure control. This study demonstrated that the USQOLCE is suitable for a North American population with evidence of its reliability and validity including its sensitivity to seizure burden.

The current study identified gender-specific correlates of hazardous drinker status as defined by the AUDIT. A total of 462 college student volunteers completed the study in 2006. The sample was predominantly Caucasian (75%) and female (55%). Participants completed a survey assessing demographics, alcohol use patterns, and health indices. Scores of 8 or more on the AUDIT defined the at-risk subsample. Logistic regression models determined which variables predicted AUDIT risk status for men and women. The at-risk participants reported higher alcohol use and related problems, elevated sleep problems and lower health ratings. High typical blood alcohol concentration (BAC), lifetime drug use, and psychosocial problems predicted risk status for males. Binge frequency and psychosocial problems predicted risk status for females. Different behavioral profiles emerged for men and women identified as hazardous drinkers on the AUDIT. The efficacy of brief alcohol interventions could be enhanced by addressing these behavioral correlates.

Chronic pancreatitis is a significant medical problem that impacts a large number of patients worldwide. In 2014, we developed a disease-specific instrument for the evaluation of quality of life in this group of patients: pancreatitis quality of life instrument (PANQOLI). The goal of this study was to evaluate its psychometric properties: its reliability and its construct validity. This is a cross-sectional multi-center study that involved 12 pancreatic disease centers. Patients who met the inclusion/exclusion criteria for chronic pancreatitis were invited to participate. Those who accepted were asked to complete seven questionnaires/instruments. Only patients who completed the PANQOLI were included in the study. Its reliability and its construct validity were tested. A total of 159 patients completed the PANQOLI and were included in the study. They had a mean age of 49.03, 49% were male, and 84% were Caucasian. Six of the 24 items on the scale were removed because of lack of inter-item correlation, redundancy, or lack of correlation to quality of life issues. The final 18-item scale had excellent reliability (Cronbach's alpha coefficient: 0.914) and excellent construct validity with good correlation to generic quality of life instruments (SF-12 and EORTC QLQ-C30/QLQ-PAN26) and lack of correlation to non-quality of life instruments (MAST and DAST). Through exploratory factor analysis, the PANQOLI was found to consist of four subscales: emotional function scale, role function scale, physical function scale, and "self-worth" scale. PANQOLI is the first disease-specific instrument to be developed and validated for the evaluation of quality of life in chronic pancreatitis patients. It has a unique subscale for "self-worth" that differentiates it from other generic instruments. Studies are currently under way to evaluate its use in other populations not included in this study.

Mucilaginous polysaccharide extracted from Dalbergia sissoo Roxb. leaves has a number of medicinal applications. Molecular weight studies and correlation analysis of the structure of polysaccharide with oligosaccharides can be helpful for further utilisation, modification and structure-activity relationship for biological applications. To determine molecular weight of medicinally important polysaccharide. To establish an unequivocal correlation of the polysaccharide monosugars with constituting oligosaccharides and glucuronic acid content based on gas-liquid chromatography (GLC) with the spectrophotometric method. Complete and partial hydrolytic studies of pure polysaccharide yielded constituting monosugars and oligosaccharides. The ratio of sugars in polysaccharide and oligosaccharides was studied by preparation of alditol acetates and analysed using GLC. The uronic acid content was studied by GLC analysis and spectrophotometry. Molecular weight of the polysaccharide was determined using the viscometric method. Dalbergia sissoo leaves yielded 14.0% pure polysaccharide, containing 15.7% of glucuronic acid. Complete hydrolysis and GLC analysis of alditol acetate derivatives of reduced and unreduced monosugars indicated the presence of L-rhamnose, D-glucuronic acid, D-galactose and D-glucose in 1.00:1.00:2.00:2.33 molar ratios. Partial hydrolysis followed by monosugar analysis of oligosaccharides established the monosugar ratio in complete agreement with polysaccharide, thereby corroborating the sugar ratio. Similar uronic acid content was obtained by GLC and spectrophotometry. The polysaccharide had an average molecular weight of 1.5 × 10⁵  Da. The study has established an obvious correlation of the structure of polysaccharide with oligosaccharides, leading to unambiguous identification of monosaccharides, which normally is not studied conclusively while reporting the polysaccharide structure. The molecular weight of the polysaccharide was determined. Copyright © 2012 John Wiley & Sons, Ltd.

Davisson-Germer Prize in Atomic or Surface Physics: The COLTRIMS multi-particle imaging technique-new Insight into the World of Correlation

The correlated many-particle dynamics in Coulombic systems, which is one of the unsolved fundamental problems in AMO-physics, can now be experimentally approached with so far unprecedented completeness and precision. The recent development of the COLTRIMS technique (COLd Target Recoil Ion Momentum Spectroscopy) provides a coincident multi-fragment imaging technique for eV and sub-eV fragment detection. In its completeness it is as powerful as the bubble chamber in high energy physics. In recent benchmark experiments quasi snapshots (duration as short as an atto-sec) of the correlated dynamics between electrons and nuclei has been made for atomic and molecular objects. This new imaging technique has opened a powerful observation window into the hidden world of many-particle dynamics. Recent multiple-ionization studies will be presented and the observation of correlated electron pairs will be discussed.

We study the long-range spatial correlations between intensity fluctuations in speckles formed by multiply scattered light. The correlation function between intensity fluctuations at the opposite boundaries of the slab are analyzed under the conditions of circular polarization memory. It shown that, until the scattered light is depolarized completely, the polarization and scalar contributions to the correlation function are of the same order of magnitude. As the slab thickness increases, their ratio falls off in inverse proportion to the thickness.

Altered immune functioning has been demonstrated in individuals with autism spectrum disorder (ASD). The current study explores the relationship between perceived immune functioning and experiencing ASD traits in healthy young adults. N = 410 students from Utrecht University completed a survey on immune functioning and autistic traits. In addition to a 1-item perceived immune functioning rating, the Immune Function Questionnaire (IFQ) was completed to assess perceived immune functioning. The Dutch translation of the Autism-Spectrum Quotient (AQ) was completed to examine variation in autistic traits, including the domains "social insights and behavior", "difficulties with change", "communication", "phantasy and imagination", and "detail orientation". The 1-item perceived immune functioning score did not significantly correlate with the total AQ score. However, a significant negative correlation was found between perceived immune functioning and the AQ subscale "difficulties with change" (r = -0.119, p = 0.019). In women, 1-item perceived immune functioning correlated significantly with the AQ subscales "difficulties with change" (r = -0.149, p = 0.029) and "communication" (r = -0.145, p = 0.032). In men, none of the AQ subscales significantly correlated with 1-item perceived immune functioning. In conclusion, a modest relationship between perceived immune functioning and several autistic traits was found.

The Trail Making Test is a popular neuropsychological test and its interpretation has traditionally used time-based scores. This study examined an alternative approach to scoring that is simply based on the examinees' ability to complete the test. If an examinee is able to complete Trails B successfully, they are coded as "completers"; if not, they are coded as "noncompleters." To assess this approach to scoring Trails B, the performance of 97 diagnostically heterogeneous individuals referred for a dementia evaluation was examined. In this sample, 55 individuals successfully completed Trails B and 42 individuals were unable to complete it. Point-biserial correlations indicated a moderate-to-strong association (r(pb)=.73) between the Trails B completion variable and the Total Scale score of the Repeatable Battery for the Assessment of Neurological Status (RBANS), which was larger than the correlation between the Trails B time-based score and the RBANS Total Scale score (r(pb)=.60). As a screen for dementia status, Trails B completion showed a sensitivity of 69% and a specificity of 100% in this sample. These results suggest that dichotomous scoring of Trails B might provide a brief and clinically useful measure of dementia status.

Bryan, Angela; Rocheleau, Courtney A.; Robbins, Reuben N.; Hutchison, Kent E.

2005-01-01

The goal of this study was the exploration of distal effects of alcohol use on condom use. Criminally involved adolescents completed an initial measure of attitudes, beliefs, and prior behavior. Of the 300 who completed the initial measurement, 267 (89%) completed a behavioral assessment 6 months later. Analyses validated a theoretical model of condom use intentions and indicated that intentions and attitudes measured at baseline were significant predictors of condom use behavior 6 months later. Neither alcohol use nor alcohol problems moderated relationships among model variables or the influence of intentions and attitudes on behavior. The findings do not support a distal role for alcohol use in altering the cognitive correlates of condom use intentions and behavior among high-risk adolescents. PMID:15755227

2009-01-01

Patients with schizophrenia (n = 41) and healthy comparison participants (n = 46) completed neuropsychological measures of intelligence, memory, and executive function. A subset of each group also completed magnetic resonance diffusion tensor imaging (DTI) studies (fractional anisotropy and cross-sectional area) of the uncinate fasciculus (UF) and cingulate bundle (CB). Patients with schizophrenia showed reduced levels of functioning across all neuropsychological measures. In addition, selective neuropsychological–DTI relationships emerged. Among patients but not controls, lower levels of declarative–episodic verbal memory correlated with reduced left UF, whereas executive function errors related to performance monitoring correlated with reduced left CB. The data suggested abnormal DTI patterns linking declarative–episodic verbal memory deficits to the left UF and executive function deficits to the left CB among patients with schizophrenia.

This study documented the treatment cascade for engagement in care and abstinence at treatment exit as well as examined correlates of these outcomes for the first certified Matrix Model® substance abuse treatment site in Sub-Saharan Africa. This retrospective chart review conducted at a resource-limited community clinic in Cape Town, South Africa, assessed treatment readiness and substance use severity at treatment entry as correlates of the number of sessions attended and biologically confirmed abstinence at treatment exit among 986 clients who initiated treatment from 2009-2014. Sociodemographic and clinical correlates of treatment outcomes were examined using logistic regression, modeling treatment completion and abstinence at treatment exit separately. Of the 2,233 clients who completed screening, approximately 44% (n = 986) initiated treatment. Among those who initiated treatment, 45% completed at least four group sessions, 30% completed early recovery skills training (i.e., at least eight group sessions), and 13% completed the full 16-week program. Approximately half (54%) of clients who provided a urine sample had negative urine toxicology results for any substance at treatment exit. Higher motivation at treatment entry was independently associated with greater odds of treatment completion and negative urine toxicology results at treatment exit. Findings provide initial support for the successful implementation the Matrix Model in a resource-limited setting. Motivational enhancement interventions could support treatment initiation, promote sustained engagement in treatment, and achieve better treatment outcomes.

Benefits of completing homework for students with different aptitudes in an introductory electricity and magnetism course

Kontur, F. J.; de La Harpe, K.; Terry, N. B.

2015-06-01

We examine how student aptitudes impact how much students learn from doing graded online and written homework in an introductory electricity and magnetism course. Our analysis examines the correlation between successful homework completion rates and exam performance as well as how changes in homework completion correlate with changes in exam scores for students with different physics aptitudes. On average, successfully completing many homework problems correlated to better exam scores only for students with high physics aptitude. On the other hand, all other students showed zero or even a negative correlation between successful homework completion and exam performance. Low- and medium-aptitude students who did more homework did no better and sometimes scored lower on exams than their low- and medium-aptitude peers who did less homework. Our work also shows that long-term changes in homework completion correlated to long-term changes in exam scores only for students with high physics aptitude, but not for students with medium or low aptitude. We offer several explanations for the disparity in homework learning gains, including cognitive load theory, ineffective homework strategies, and various mismatches between homework and exams. Several solutions are proposed to address these possible deficiencies in graded online and written homework.

Group hypnotherapy for irritable bowel syndrome with long-term follow-up.

PubMed

Gerson, Charles D; Gerson, Jessica; Gerson, Mary-Joan

2013-01-01

This study tested whether group gut-focused hypnotherapy would improve irritable bowel syndrome (IBS). Several possible outcome predictors were also studied. Before treatment, 75 patients completed a Symptom Severity Scale, a Mind-Body attribution questionnaire, and a Quality of Relationship Inventory (QRI). The symptom scale was completed posttreatment, 3, 6, and 12 months later. There was significant symptom reduction at each data point (p < .001). Sixty percent had a reduction of more than 50 points, indicative of clinical improvement. Initial severity score (p = .0004) and QRI conflict (p = .057) were directly correlated with a response to hypnotherapy, while attribution of symptoms to mind (emotional) causation was inversely correlated (p = .0056). The authors conclude that group hypnotherapy is effective in patients with IBS.

2018-07-01

The Memorial Symptom Assessment Scale Short Form (MSAS-SF) is a widely used symptom assessment instrument. Patients who self-complete the MSAS-SF have difficulty following the two-part response format, resulting in incorrectly completed responses. We describe modifications to the response format to improve useability, and rational scoring rules for incorrectly completed items. The modified MSAS-SF was completed by 311 women in our Peer and Nurse support Trial to Assist women in Gynaecological Oncology; the PeNTAGOn study. Descriptive statistics were used to summarise completion of the modified MSAS-SF, and provide symptom statistics before and after applying the rational scoring rules. Spearman's correlations with the Functional Assessment for Cancer Therapy-General (FACT-G) and Hospital Anxiety and Depression Scale (HADS) were assessed. Correct completion of the modified MSAS-SF items ranged from 91.5 to 98.7%. The rational scoring rules increased the percentage of useable responses on average 4% across all symptoms. MSAS-SF item statistics were similar with and without the scoring rules. The pattern of correlations with FACT-G and HADS was compatible with prior research. The modified MSAS-SF was useable for self-completion and responses demonstrated validity. The rational scoring rules can minimise loss of data from incorrectly completed responses. Further investigation is recommended.

Background: Self-efficacy is believe in and feeling of ability to complete work. One of these factors is educational teachers’ role. This study aimed to determine relationship between teachers’ leadership style and students’ self-efficacy in midwifery students. Method: This Study is a cross sectional correlation study. Sampling was conducted in midwifery students in Bachelor Science degree in 2013. Data collection tools were multi leadership questionnaire and self-efficacy clinical performance. After explaining the goals of study, 97 students completed the questionnaire. Scoring the questionnaire was based on a Liker’s scale (0-5). Data were analyzed by SPSS 16. Correlation coefficient test was adopted to investigate the relationship and p value was considered 0.05. Result: Mean of self-efficacy scores were 116.12 (24.66.). In 53.3% of the cases, self-efficacy was good, in 42.2% moderate and in 4.3%, it was bad. The majority of the students (88.9%) reported that their teachers had an idealized style in leadership. About 94.6% of the students with good self- efficacy believed that their teachers’ leadership style was transformational style. There was a significant correlation between self- efficacy and leadership style (p<0.05). Conclusions: Results showed that transformational style is appropriate for midwifery teachers. PMID:26925916

Positron emission tomography (PET) / computed tomography (CT) is among the most frequently used imaging modalities for initial staging of gastro-oesophageal (GE) cancer, whereas CT-perfusion (CTP) provides different multiparametric information. This proof of concept study compares CTP- and PET-parameters in patients with GE cancer to evaluate correlations and a possible prognostic value of a combined PET/CTP imaging procedure. A total of 31 patients with F-18-FDG-PET/CT and CTP studies were prospectively analysed. Patients had adenocarcinoma (n = 22) and oesophageal squamous cell carcinoma (SCC, n = 9). Imaging was performed before start of treatment. CTP parameters [blood flow (BF), blood volume (BV), mean transit time (MTT)] and metabolic parameters [(maximum and mean standardised uptake values and standard deviation (SUVmax, SUVmean, SUVsd), metabolic tumour volume (MTV) and tumour lesion glycolysis (TLG)], as well as flow metabolic product [FMP (BF × SUVmax)] were determined and their relationship was compared. Additionally their association to clinical parameters (differentiation grading, staging, HER2-status, follow-up status) and to histopathological regression (post-neoadjuvant regression grading) was evaluated. Correlation between parameters of both modalities was significant between MTT and MTV (r = 0.375, p = 0.038); no other significant correlation was found. Patients with complete histopathological regression showed significantly lower BF and BV than patients with nearly complete or partial response. TLG and regression grading showed significant correlation with staging. All other quantitative parameters for CTP and PET data did not correlate significantly with histopathological regression grading, differentiation or staging. The combination of PET and CTP parameters (FMP) showed no significant prognostic value. Significant correlations were only found between MTT and MTV, which indicates a possible perfusional/metabolic coupling. Therefore, pre-therapeutic CTP and PET- parameters provide complementary information about the pre-therapeutic tumour status and are not interchangeable. Only CTP parameters might be able to predict complete histopathological regression. On the other hand, only PET parameters are correlated with staging.

Completion of secondary education is important for individuals' future health and health behaviour. The fundamental purpose of this study is to investigate the variation and clustering of school completion in families and neighbourhoods. Secondly, we aim to examine the impact of individuals' family structure and neighbourhood of residence and examine to what extent parental education level moderates these associations. Longitudinal register data for 30% of the entire Norwegian population aged 21-27 years in 2010 (N = 107,003) was extracted from Statistic Norway´s event database. Three-level logistic regression models, which incorporated individual, family, and neighbourhood contextual factors, were applied to estimate the family and neighbourhood general contextual effects and detect possible educational differences in the impact of family structure and urban place of residence in school completion. Completion rates were significantly higher within families with higher education level (79% in tertiary educated families vs. 61% and 48% in secondary and primary educated families respectively) and were strongly correlated within families (ICC = 39.6) and neighbourhoods (ICC = 5.7). Several structural factors at the family level negatively associated with school completion (e.g., family disruption, large family size, and young maternal age) were more prevalent and displayed more negative impact among primary educated individuals. Urban residence was associated with school completion, but only among the tertiary educated. Investment in the resources in the individuals' immediate surroundings, including family and neighbourhood, may address a substantial portion of the social inequalities in the completion of upper secondary education. The high intra-familial correlation in school completion suggests that public health policies and future research should acknowledge family environments in order to improve secondary education completion rates among young people within lower educated families.

2018-01-01

The aim of this study was to establish the normative data of dentofacial transverse dimensions according to the skeletal maturation stage in Korean adolescents with good occlusion, assess gender differences and determine correlations between transverse variables. A total of 577 Korean subjects between ages 7 to 19 years and exhibiting skeletal Class I occlusion were categorized by skeletal maturation index (SMI) of Fishman using hand-wrist radiographs. Dentofacial transverse dimensions were assessed using posteroanterior cephalograms. Independent two-sample t -tests were used to analyze differences between genders. Pearson correlation coefficient was used to determine the correlation between transverse measurements. Dentofacial transverse norms relevant to skeletal maturation stages were established. The average maxillomandibular width difference and ratio at growth completion was 22.16 mm and 77.01% for males; 23.70 mm and 74.06% for females, respectively. Males had greater facial, maxillary and mandibular widths compared to females at every SMI stage. The maxillary and mandibular intermolar widths showed the strongest correlation for both sexes (r = 0.826 for males, r = 0.725 for females). Dentofacial transverse norms of Korean adolescents were established according to developmental stage. All dentofacial widths were greater in males at growth completion. Maxillary and mandibular intermolar widths were strongly correlated. This study may serve as a guideline for the assessment of dentofacial transverse growth according to skeletal maturation stage in Korean adolescents with good occlusion.

Spectroscopic and electric properties of the LiCs molecule: a coupled cluster study including higher excitations

Sørensen, L. K.; Fleig, T.; Olsen, J.

2009-08-01

Aimed at obtaining complete and highly accurate potential energy surfaces for molecules containing heavy elements, we present a new general-order coupled cluster method which can be applied in the framework of the spin-free Dirac formalism. As an initial application we present a systematic study of electron correlation and relativistic effects on the spectroscopic and electric properties of the LiCs molecule in its electronic ground state. In particular, we closely investigate the importance of excitations higher than coupled cluster doubles, spin-free and spin-dependent relativistic effects and the correlation of outer-core electrons on the equilibrium bond length, the harmonic vibrational frequency, the dissociation energy, the dipole moment and the static electric dipole polarizability. We demonstrate that our new implementation allows for highly accurate calculations not only in the bonding region but also along the complete potential curve. The quality of our results is demonstrated by a vibrational analysis where an almost complete set of vibrational levels has been calculated accurately.

Can objective measurements of the nasal form and function represent the clinical picture in unilateral cleft lip and palate?

The present study aimed to evaluate the potential correlations between objective measurements of nasal function and self-assessed nasal symptoms or clinical findings at nasal examination among adults treated for unilateral cleft lip and palate (UCLP), respectively. All UCLP patients born between 1960 and 1987 (n = 109) treated at a tertiary referring center were invited. Participation rate was 76% (n = 83) at a mean of 37 years after the initial surgery. All participants completed the same study protocol including acoustic rhinometry (AR), rhinomanometry (RM), anterior rhinoscopy, and questionnaires regarding self-experienced nasal symptoms. A reduced volume of the anterior nasal cavity on the operated side (measured by AR) correlated to an expressed wish by the patient to change the function of the nose. A similar correlation was seen for the minimal cross-sectional area of anterior nasal cavity on the operated side. Furthermore, correlations were found between smaller volume and area of nasal cavity and a greater frequency of nasal obstruction. No further correlations were found. Objective measurements partly correlate to the clinical picture among adults treated for UCLP. However, these need to be combined with findings at clinical examination and patient self-assessment to represent the complete clinical picture.

A methodology is proposed for international geological correlation studies based on LANDSAT-MSS imagery, Bullard's model of continental fit and compatible structural trends between Northeast Brazil and the West African counterpart. Six extensive lineaments in the Brazilian study area are mapped and discussed according to their regional behavior and in relation to the adjacent continental margin. Among the first conclusions, correlations were found between the Sobral Pedro II Lineament and the megafaults that surround the West African craton; and the Pernambuco Lineament with the Ngaurandere Linemanet in Cameroon. Ongoing research to complete the methodological stages includes the mapping of the West African structural framework, reconstruction of the pre-drift puzzle, and an analysis of the counterpart correlations.

School-age children's fears, anxiety, and human figure drawings.

PubMed

Carroll, M K; Ryan-Wenger, N A

1999-01-01

The purpose of this study was to identify the fears of school-age children and determine the relationship between fear and anxiety. A descriptive, correlational, secondary analysis study was conducted using a convenience sample of 90 children between the ages of 8 and 12 years. Each child was instructed to complete the Revised Children's Anxiety Scale and then answer questions from a structured interview. On completion, each child was instructed to draw a human figure drawing. Frequency charts and correlational statistics were used to analyze the data. Findings indicated that the most significant fears of the boys were in the categories of animals, safety, school, and supernatural phenomena, whereas girls were more fearful of natural phenomena. High correlations existed between anxiety scores and the number of fears and emotional indicators on human figure drawings. Because human figure drawings are reliable tools for assessing anxiety and fears in children, practitioners should incorporate these drawings as part of their routine assessments of fearful children.

Idiographic measurement of depressive thinking: development and preliminary validation of the Sentence Completion Test for Chronic Pain (SCP).

Depression is a common feature of chronic pain, but there is only limited research into the content and frequency of depressed cognitions in pain patients. This study describes the development of the Sentence Completion Test for Chronic Pain (SCP), an idiographic measure for assessing depressive thinking in chronic pain patients. The sentence completion task requires participants to finish incomplete sentences using their own words to a set of predefined stems that include negative, positive and neutral valenced self-referenced words. In addition, the stems include past, future and world stems, which reflect the theoretical negative triad typical to depression. Complete responses are coded by valence (negative, positive and neutral), pain and health-related content. A total of 89 participants were included in this study. Forty seven adult out-patients formed the depressed pain group and were compared to a non-clinical control sample of 42 healthy control participants. This study comprised several phases: (1) theory-driven generation of coding rules; (2) the development of a coding manual by a panel of experts (3) comparing reliability of coding by expert raters without the use of the coding manual and with the use of the coding manual; (4) preliminary analyses of the construct validity of the SCP. The internal consistency of the SCP was tested using the Kuder-Richardson coefficient (KR-20). Inter-rater agreement was assessed by intra-class correlations (ICC). The content and construct validity of the SCP was investigated by correlation coefficients between SCP negative completions, the Hospital Anxiety and Depression Scale (HADS) depression scores and the number of symptoms on the Structured Clinical Interview for DSM-IV-TR (SCID). As predicted for content validity, the number of SCP negative statements was significantly greater in the depressed pain group and this group also produced significantly fewer positive statements, compared to the healthy control group. The number of negative pain completions and negative health completions was significantly greater in the depressed pain group. As expected, in the depressed pain group, the correlation between SCP negatives and the HADS Depression score was r=0.60 and the correlation between SCP negatives and the number of symptoms on the SCID was r=0.56. The SCP demonstrated good content validity, internal consistency and inter-rater reliability. Uses for this measure, such as complementing questionnaire measures by an idiographic assessment of depressive thinking and generating hypotheses about key problems within a cognitive-behavioural case-formulation, are suggested.

Bad breath has a significant impact on daily life of those who suffer from it. Oral malodor may rank only behind dental caries and periodontal disease as the cause of patient's visit to dentist. An aim of this study was to use a portable sulfide monitor as a motivational tool for encouraging the patients towards the better oral hygiene by correlating the plaque scores with sulfide monitor scores, and comparing the sulfide monitor scores before and after complete prophylaxis and 3 months after patient motivation. 30 patients with chronic periodontitis, having chief complaint of oral malodor participated in this study. At first visit, the plaque scores (P1) and sulfide monitor scores before (BCR1) and after complete oral prophylaxis (BCR2) were taken. Then the patients were motivated towards the better oral hygiene. After 3 months, plaque scores (P2) and sulfide monitor scores (BCR3) were recorded again. It was done using SPSS (student package software for statistical analysis). Paired sample test was performed. Statistically significant reduction in sulfide monitor scores was reported after the complete oral prophylaxis and 3 months after patient motivation. Plaque scores were significantly reduced after a period of 3 months. Plaque scores and breathchecker scores were positively correlated. An intensity of the oral malodor was positively correlated with the plaque scores. The portable sulfide monitor was efficacious in motivating the patients towards the better oral hygiene.

Children's physical activity (PA) choices are influenced by their perceived ability (adequacy) and inclination toward (predilection) PA. The study's purpose was to determine the association of body mass index (BMI) category with PA perceptions in sixth-grade children. A total of 267 children (119 boys, 148 girls; age 11+ y; ht 1.53 SD 0.08 m; wt 49.0 SD 13.5 kg; BMI 20.7 SD 4.8) provided informed consent and completed the study. All were measured for body weight and height and completed the Children's Self-perceptions of Adequacy in and Predilection for Physical Activity (CSAPPA) scale. Spearman rank-order correlation analysis was conducted between total CSAPPA score (and three factor scores of adequacy, predilection, and enjoyment) and BMI category relative to gender, body weight classification and for all children. A significant negative correlation was identified between BMI category (p<0.01) and CSAPPA total, adequacy, and predilection score for all children. Girls (but not boys) showed significant negative correlation between BMI category and all CSAPPA scores. A significant negative correlation in BMI category and PA perceptions exists in children, with the relationship being stronger in girls. Children with increased BMI may have adverse perceptions of PA and risks for sedentary behavior.

The effects of maternal parenting style and religious commitment on self-regulation, academic achievement, and risk behavior among African-American parochial college students.

This study explored relations between religiosity, both parent and student, and maternal parenting style and student academic self-regulation, academic achievement, and risk behavior among African-American youth attending a parochial college. Eighty-five students completed self-report survey measures of religiosity, self-regulation, academic achievement, and risk behavior. Participants also completed youth report measures of parental religiosity and perceived maternal parenting style. Correlational analyses show authoritative parenting to be associated with high levels of academic performance and study skills. Additional correlations revealed that highly religious students tend to perform well academically, study better, and engage in fewer risk behaviors than youth less committed to religion. Although no direct relations were observed between parenting style and student religiosity, maternal parenting style was found to moderate relations between parental and student religiosity. Findings are discussed in terms of their relevance to the population studied.

Assessing medical students' self-regulation as aptitude in computer-based learning.

Song, Hyuksoon S; Kalet, Adina L; Plass, Jan L

2011-03-01

We developed a Self-Regulation Measure for Computer-based learning (SRMC) tailored toward medical students, by modifying Zimmerman's Self-Regulated Learning Interview Schedule (SRLIS) for K-12 learners. The SRMC's reliability and validity were examined in 2 studies. In Study 1, 109 first-year medical students were asked to complete the SRMC. Bivariate correlation analysis results indicated that the SRMC scores had a moderate degree of correlation with student achievement in a teacher-developed test. In Study 2, 58 third-year clerkship students completed the SRMC. Regression analysis results indicated that the frequency of medical students' usage of self-regulation strategies was associated with their general clinical knowledge measured by a nationally standardized licensing exam. These two studies provided evidence for the reliability and concurrent validity of the SRMC to assess medical students' self-regulation as aptitude. Future work should provide evidence to guide and improve instructional design as well as inform educational policy.

Patients with anorexia nervosa experience increased sensitivity to the risk of social rejection. The aims of this study were to assess the interpretation of ambiguous social scenarios depicting the risk of rejection and to examine the relationship between interpretation biases and clinical symptoms. Thirty-five women with anorexia nervosa and 30 healthy eaters completed clinical questionnaires, alongside a sentence completion task. This task required participants to generate completions to ambiguous social scenarios and to endorse their best completion. Responses were rated as being negative, neutral or positive. Patients endorsed more negative interpretations and fewer neutral and positive interpretations compared with healthy eaters. The frequency of endorsed negative interpretations correlated with depression, anxiety and fear of weight gain and body disturbance. A negative interpretation bias towards social stimuli is present in women with anorexia nervosa and correlates with clinical symptoms. Interventions aimed at reducing this bias could improve illness prognosis.

Barkan, I Yu; Stafeev, A A; Repin, V S

2015-01-01

Patients with full adentia are characterized by the formation of specific psycho-emotional status. Rational psychotherapeutic support of these patients largely determines the efficiency of dental prosthetic treatment. At the same time, the definition of mental and emotional status is not included in the diagnostic examination protocol. Considering the above the purpose of the study was to evaluate mental and emotional status of patients receiving complete dentures. Prosthetic rehabilitation of 30 patients with complete teeth loss was performed and clinical evaluation and evaluation of mental and emotional status were carried out before and after treatment. Patients with negative experiences of prosthetics showed a higher level of personal and situational anxiety. There was correlation of adaptation to removable dentures and the patient's personality traits. It is determined that emotional instability during treatment tends to decrease affecting the timing of adaptation to complete dentures. It is noted that patients with repeated prosthetics have earlier recovery of coordination ability of the masticatory muscles.

ABSTRACT Low pressure Pain Threshold (PPT) is considered a risk factor for Temporomandibular Disorders (TMD) and is influenced by psychological variables. Objectives To correlate deep pain sensitivity of masticatory muscles with prosthetic factors and Oral-Health-Related Quality of Life (OHRQoL) in completely edentulous subjects. Material and Methods A total of 29 complete denture wearers were recruited. The variables were: a) Pressure Pain Threshold (PPT) of the masseter and temporalis; b) retention, stability, and tooth wear of dentures; c) Vertical Dimension of Occlusion (VDO); d) Oral Health Impact Profile (OHIP) adapted to orofacial pain. The Kolmogorov-Smirnov test, the Pearson Product-Moment correlation coefficient, the Spearman Rank correlation coefficient, the Point-Biserial correlation coefficient, and the Bonferroni correction (α=1%) were applied to the data. Results The mean age (standard deviation) of the participants was of 70.1 years (9.5) and 82% of them were females. There were no significant correlations with prosthetic factors, but significant negative correlations were found between the OHIP and the PPT of the anterior temporalis (r=-0.50, 95% CI-0.73 to 0.17, p=0.005). Discussion The deep pain sensitivity of masticatory muscles in complete dentures wearers is associated with OHRQoL, but not with prosthetic factors. PMID:26814457

Woon, D. E.

1997-01-01

The A2 pi <-- X2 sigma+ transition in MgCCH was studied with correlation consistent basis sets and single- and multireference correlation methods. The A2 pi excited state was characterized in detail; the x2 sigma+ ground state has been described elsewhere recently. The estimated complete basis set (CBS) limits for valence correlation, including zero-point energy corrections, are 22668, 23191, and 22795 for the RCCSD(T), MRCI, and MRCI + Q methods, respectively. A core-valence correction of +162 cm-1 shifts the RCCSD(T) value to 22830 cm-1, in good agreement with the experimental result of 22807 cm-1.

This study aimed to examine Theory of Mind (ToM) and social competence in children and adolescents with genetic generalised epilepsy (GGE), and explore how they relate to neurocognitive and epilepsy variables. Twenty-two children and adolescents with GGE (8-16 years old) and 22 typically developing controls completed two behavioural tasks (faux-pas, strange stories) assessing cognitive and affective ToM, and a battery of standardised neuropsychological tests. Parents completed questionnaires assessing ToM and social competence. Neurologists completed the Global Assessment Severity of Epilepsy (GASE) scale to measure of epilepsy severity. Children and adolescents with GGE were impaired in both cognitive and affective ToM, and had reduced social competence compared to controls, which was not attributable to low intellectual functioning or impaired executive skills (working memory, inhibition). Lower ToM correlated with reduced social competence in children and adolescents with GGE. Clinical variables identified included: (i) higher daily dosage of valproate, which was correlated with reduced affective ToM, (ii) higher daily dosages of ethosuximide and lamotrigine, which were correlated with reduced social competence, and (iii) overall epilepsy severity on the GASE, which was correlated with reduced social competence. Our study revealed cognitive and affective ToM impairments in children and adolescents with GGE, which correlated with everyday social problems. Moreover, higher dosages of commonly prescribed anti-epileptic drugs and overall epilepsy severity were related to ToM impairments and social competence problems. Although preliminary, these findings provide critical information for detection and screening procedures for social difficulties in children and adolescents with GGE, which are currently lacking.

Purpose The SLICC Damage Index (SDI) is a validated instrument for assessing organ damage in systemic lupus erythematosus (SLE). Trained physicians must complete it, limiting utility where this is impossible. Methods We developed and pilot-tested a self-assessed organ damage instrument, the Lupus Damage Index Questionnaire (LDIQ), in 37 SLE subjects and 7 physicians. After refinement, 569 English-speaking SLE subjects and 14 rheumatologists from 11 international SLE clinics participated in validation. Subjects and physicians completed instruments separately. We calculated sensitivity, specificity, Spearman correlations and agreement, using the SDI as gold standard. 605 SLE participants in the community-based National Data Bank for Rheumatic Diseases (NDB) study completed the LDIQ and we assessed correlations with outcome and disability measures. Results Mean LDIQ score was 3.3 (0-16) and mean SDI score was 1.5 (0-9). LDIQ had a moderately high correlation with SDI (Spearman r=0.50, p<0.001). Specificities of individual LDIQ items were >80%, except for neuropathy. Sensitivities were variable and lowest for damage with <1% prevalence. Agreement between SDI and LDIQ was > 85% for all but neuropathy, reduced renal function, deforming arthritis and alopecia. In the NDB, LDIQ correlated well with comorbidity index (r=0.45), SF-36 physical component scale (0.43), Medical Research Council dyspnea scale (0.40), disability (0.37) and SLE Activity Questionnaire score (0.37). Conclusions The LDIQ’s metric properties are good compared to the SDI. It has construct validity and correlations with health assessments similar to the SDI. The LDIQ should allow expansion of SLE research. Its ultimate value will be determined in longitudinal studies. PMID:20391512

The current study examined the romantic relationships of individuals with obsessive-compulsive disorder (OCD). Participants were 64 individuals recruited from a national conference who completed measures of OCD symptoms, depressive symptoms, intimacy, self-disclosure, relationship satisfaction, and relationship worry. Severity of obsessions was negatively correlated with intimacy, relationship satisfaction, and self-disclosure. In contrast, two compulsive behaviors (washing and neutralizing) were positively correlated with several relationship variables. Fears of contamination from sexual activity were positively correlated with the severity of OCD symptoms. The clinical implications of the findings from this study and suggestions for future research are presented.

Although the Insomnia Severity Index (ISI) is already administered online, this frequently used instrument has not been validated for Web delivery. This study compares online and paper-and-pencil ISI versions completed by participants in a randomized controlled trial testing an Internet-delivered intervention for insomnia. Forty-three adults with insomnia completed both ISI versions during pre- (Assessment 1) and post-intervention (Assessment 2). Correlations between total scores of both versions were significant (rs ≥ .98, ps < .001). For both ISI versions, internal consistency was acceptable (Assessment 1, α = .61; Assessment 2, α ≥ .88). Among participants not receiving the parent study intervention, correlations between 1 format at Assessment 1 and the alternative format at Assessment 2 were generally significant (rs = .26-.82). Together, findings suggest the ISI can be delivered online.

Anxiety sensitivity and self-reported reasons for drug use.

PubMed

Stewart, S H; Karp, J; Pihl, R O; Peterson, R A

1997-01-01

Two studies examined the relationships between anxiety sensitivity (AS), drug use, and reasons for drug use. In Study 1, 229 university students (57% F) completed the Anxiety Sensitivity Index (ASI) and a drug use survey, assessing use of a variety of drugs within the last month, and coping reasons for drug use. Consistent with a modified tension-reduction hypothesis, ASI scores were positively correlated with the number of both anxiety- and depression-related reasons for drug use endorsed. In Study 2, 219 university students (74% F) completed the ASI and a drug use survey, assessing use of several drugs (e.g., alcohol, cigarettes, caffeine, and marijuana/hashish) within the last year, and primary reasons (coping, affiliative, or enhancement) for the use of each drug. Marijuana/hashish users reported lower ASI scores than non-users supporting a negative relation between AS and the use of cannabis. ASI scores were positively correlated with the use of alcohol primarily to cope, and negatively correlated with the use of alcohol primarily to affiliate, among both gender groups, and ASI scores were positively correlated with the use of nicotine primarily to cope among the females. Implications of these findings for understanding risk for abuse of stress-response-dampening drugs by high AS individuals are discussed.

To assess the level of agreement between children and their parents when reporting a child's food consumption. Cross-sectional study in which children and parents independently completed 7 d food diaries describing the foods and drinks the child consumed at every meal and snack. The association between child and parent reporting was assessed for nineteen food groups using Kendall's tau-b non-parametric correlations, Spearman's rank correlations, kappa coefficients and Lin's concordance measure of agreement. Results were also stratified by gender of the child and his/her grade at school. Households in Ticino, Switzerland, April-June 2014. Two hundred and ninety-nine children aged 6-12 years and one of their parents participated, with 264 providing complete data (35 % completion rate). Results showed a high level of agreement between child and parent reporting. Spearman correlations ranged from 0·55 (sauces) and 0·57 (fatty meat) to 0·80 (fruit), 0·83 (starchy foods) and 0·84 (pastries). All nineteen Spearman correlations were significant at the 0·001 level. Kendall's tau-b correlations ranged from 0·44 (fat meat) to 0·81 (puff pastry). Kappa values showed low to high levels of agreement, ranging from 0·15 (sweets) to 0·77 (puff pastry). Lin's concordance correlation coefficients ranged from 0·39 (whole grains) to 0·86 (puff pastry). When assessing the eating behaviour of children using a 7 d food diary, children's reports might be as reliable as their parents'.

Reporter-Interpreter-Manager-Educator (RIME) descriptive ratings as an evaluation tool in an emergency medicine clerkship.

PubMed

Ander, Douglas S; Wallenstein, Joshua; Abramson, Jerome L; Click, Lorie; Shayne, Philip

2012-10-01

Emergency Medicine (EM) clerkships traditionally assess students using numerical ratings of clinical performance. The descriptive ratings of the Reporter, Interpreter, Manager, and Educator (RIME) method have been shown to be valuable in other specialties. We hypothesized that the RIME descriptive ratings would correlate with clinical performance and examination scores in an EM clerkship, indicating that the RIME ratings are a valid measure of performance. This was a prospective cohort study of an evaluation instrument for 4(th)-year medical students completing an EM rotation. This study received exempt Institutional Review Board status. EM faculty and residents completed shift evaluation forms including both numerical and RIME ratings. Students completed a final examination. Mean scores for RIME and clinical evaluations were calculated. Linear regression models were used to determine whether RIME ratings predicted clinical evaluation scores or final examination scores. Four hundred thirty-nine students who completed the EM clerkship were enrolled in the study. After excluding items with missing data, there were 2086 evaluation forms (based on 289 students) available for analysis. There was a clear positive relationship between RIME category and clinical evaluation score (r(2)=0.40, p<0.01). RIME ratings correlated most strongly with patient management skills and least strongly with humanistic qualities. A very weak correlation was seen with RIME and final examination. We found a positive association between RIME and clinical evaluation scores, suggesting that RIME is a valid clinical evaluation instrument. RIME descriptive ratings can be incorporated into EM evaluation instruments and provides useful data related to patient management skills. Copyright © 2012 Elsevier Inc. All rights reserved.

Pubic Hair Shaving Is Correlated to Vulvar Dysplasia and Inflammation: A Case-Control Study

Malik, Eduard

2017-01-01

Objective The risk factors for vulvar dysplasia and infections are not fully known. In this study, we aimed to investigate the correlation between pubic hair shaving and the occurrence of vulvar inflammation, dysplasia, and cancer. Methods This study was performed between January 2013 and December 2016 in which a standardized questionnaire concerning genital hair shaving was administered to vulvar dysplasia and cancer patients and healthy participants. The presence of human papilloma virus (HPV) infection and the occurrence of genital inflammation were documented. Results We recruited 49 patients with vulvar dysplasia or cancer and 234 healthy women as a control group. Smoking, HPV infection, genital inflammation, and complete pubic hair removal were significantly more common in the vulvar dysplasia/cancer group. Pubic hair shaving per se presented a clear association with vulvar dysplasia/cancer. Shaving the labia majora in particular showed also an association. Conclusion Our findings suggest that partial or complete pubic hair shaving using a razor is correlated with and could be a potential risk factor for the development of genital inflammation, vulvar dysplasia, and malignancies. These results need to be confirmed in larger studies. HPV status and genital inflammation should be documented by medical personnel. PMID:29104417

The Families Defeating Diabetes intervention evaluated a postpartum healthy living program for women with recent gestational diabetes mellitus (GDM). Randomized controlled trial. Tertiary centers in London, Calgary, and Victoria, Canada. Women with GDM and partners; 46% of eligible maternal participants agreed to participate. Interventional (INT) participants received a healthy living seminar at 3 months; access to a walking group/Website; biweekly e-mails. Control (CON) participants received a contemporary postpartum diabetes prevention handout. Maternal, partner, and offspring demographics at baseline, 3, and 12 months. Percentages of women losing ≥7% of postpartum weight were compared by χ 2 testing; body habitus comparisons by analysis of covariance (ANCOVA); maternal A1C comparisons by unpaired t tests; participant outcome associations by Pearson correlation coefficients. Maternal participants were 170 (89 INT and 81 CON) with 63 partners (30 INT and 33 CON); 103 (73 maternal; 30 partners) were lost to follow-up; 57% of maternal participants completed 12 months; 33% INT women (n = 50) lost ≥7% weight versus 25% CON women (n = 47), P = .43. Interventional participant results did not correlate with accession of study elements. Maternal completion was significantly associated with partner involvement, breastfeeding, higher income, and education. Paternal weights correlated significantly with maternal and offspring weights. Families Defeating Diabetes outcomes were not significantly different for INT maternal or paternal participants versus CON participants. Secondary outcomes of future value included statistically significant positive associations between paternal participation, socioeconomic indicators, and maternal study completion, significant correlations between maternal, paternal, and offspring weights as well as insights into study component engagement.

The Migraine Disability Assessment (MIDAS) Questionnaire is a reliable and valid instrument for migraine-related disability. Such a tool is needed to quantify migraine-related disability in the Greek population. This validation study aims to assess the test-retest reliability, internal consistency, item discriminant and convergent validity of the Greek translation of the MIDAS. Adults diagnosed with migraine completed the MIDAS Questionnaire on two occasions 3 weeks apart to assess reliability, and completed the RAND-36 to assess validity. Participants (n = 152) had a median MIDAS score of 24 and mostly severe disability (58% were grade IV). The test-retest reliability analysis (N = 59) revealed excellent reliability for the total score. Internal consistency was α = 0.71 for initial and α = 0.82 for retest completion. For item discriminant validity, the correlations between each question and the total score were significant, with high correlations for questions 2-5 (range 0.67 ≤ r ≤ 0.79; p < 0.01). For convergent validity, there was significant negative correlation between the total score and all RAND-36 subscales except for 'emotional wellbeing'. The negative correlation indicates that patients with a lower degree of disability according to their MIDAS score tended to have better wellbeing. Psychometric properties are comparable with those of other published validation studies of the MIDAS and the original. Findings on question 1 show that missing work/school days may be closely related with increased affect issues. The Greek version of the MIDAS Questionnaire has good reliability and validity. This study allowed for cross-cultural comparability of research findings.

Gross motor competence confers health benefits, but levels in children and adolescents are low. While interventions can improve gross motor competence, it remains unclear which correlates should be targeted to ensure interventions are most effective, and for whom targeted and tailored interventions should be developed. The aim of this systematic review was to identify the potential correlates of gross motor competence in typically developing children and adolescents (aged 3-18 years) using an ecological approach. Motor competence was defined as gross motor skill competency, encompassing fundamental movement skills and motor coordination, but excluding motor fitness. Studies needed to assess a summary score of at least one aspect of motor competence (i.e., object control, locomotor, stability, or motor coordination). A structured electronic literature search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Six electronic databases (CINAHL Complete, ERIC, MEDLINE Complete, PsycINFO ® , Scopus and SPORTDiscus with Full Text) were searched from 1994 to 5 August 2014. Meta-analyses were conducted to determine the relationship between potential correlates and motor competency if at least three individual studies investigated the same correlate and also reported standardized regression coefficients. A total of 59 studies were identified from 22 different countries, published between 1995 and 2014. Studies reflected the full range of age groups. The most examined correlates were biological and demographic factors. Age (increasing) was a correlate of children's motor competence. Weight status (healthy), sex (male) and socioeconomic background (higher) were consistent correlates for certain aspects of motor competence only. Physical activity and sport participation constituted the majority of investigations in the behavioral attributes and skills category. Whilst we found physical activity to be a positive correlate of skill composite and motor coordination, we also found indeterminate evidence for physical activity being a correlate of object control or locomotor skill competence. Few studies investigated cognitive, emotional and psychological factors, cultural and social factors or physical environment factors as correlates of motor competence. This systematic review is the first that has investigated correlates of gross motor competence in children and adolescents. A strength is that we categorized correlates according to the specific ways motor competence has been defined and operationalized (object control, motor coordination, etc.), which enables us to have an understanding of what correlates assist what types of motor competence. Indeed our findings do suggest that evidence for some correlates differs according to how motor competence is operationalized.

Objective The aim of this study was to establish the normative data of dentofacial transverse dimensions according to the skeletal maturation stage in Korean adolescents with good occlusion, assess gender differences and determine correlations between transverse variables. Methods A total of 577 Korean subjects between ages 7 to 19 years and exhibiting skeletal Class I occlusion were categorized by skeletal maturation index (SMI) of Fishman using hand-wrist radiographs. Dentofacial transverse dimensions were assessed using posteroanterior cephalograms. Independent two-sample t-tests were used to analyze differences between genders. Pearson correlation coefficient was used to determine the correlation between transverse measurements. Results Dentofacial transverse norms relevant to skeletal maturation stages were established. The average maxillomandibular width difference and ratio at growth completion was 22.16 mm and 77.01% for males; 23.70 mm and 74.06% for females, respectively. Males had greater facial, maxillary and mandibular widths compared to females at every SMI stage. The maxillary and mandibular intermolar widths showed the strongest correlation for both sexes (r = 0.826 for males, r = 0.725 for females). Conclusions Dentofacial transverse norms of Korean adolescents were established according to developmental stage. All dentofacial widths were greater in males at growth completion. Maxillary and mandibular intermolar widths were strongly correlated. This study may serve as a guideline for the assessment of dentofacial transverse growth according to skeletal maturation stage in Korean adolescents with good occlusion. PMID:29291187

The aims of this study were to clarify the geographic distribution of complete cell death in the radiofrequency ablated area in a porcine liver experiment, and to evaluate the efficacy of ultrasonography using contrast media in detecting the area of Radiofrequency-induced cell death. Radiofrequency ablation was performed at 3 sites in each liver in seven swine with a RF2000TM radiofrequency generator using an expandable type needle electrode. The ablation area was investigated histologically by Hematoxylin-Eosin staining and NADH staining. The area of radiofrequency-induced cell death was correlated to the ultrasonographic findings using contrast media, by means of contrast harmonic imaging, flash echo imaging-subtraction and flash echo imaging-power Doppler. The ablation area showed three distinct regions. Although the HE staining did not indicate necrosis, the NADH staining showed a complete loss of cellular activity in the inner and middle layers of the ablation area. However, in the outer layer cells displaying cellular integrity were intermingled with the necrotic cells, indicating that some of the cells in this layer had a chance to survive. Further, in some cases the outer layer of the ablated area had irregular margins. The flash-echo power-doppler images were accurately correlated in size and shape to the pathologically proved region of complete cell death in the radiofrequency-induced lesions. In the marginal part of the radiofrequency ablation area, cell death was incomplete. Flash echo imaging-power doppler was a useful and sensitive real time imaging technique for accurate evaluation of the region of complete cell death.

The purpose of the study is to evaluate the relationship between NIH-CPSI and IIEF-5 in Chinese men with CP/CPPS. A large cross-sectional and multicenter survey was conducted from July 2012 to January 2014. Men were recruited from urology clinics which were located at the five cities in China. All men participated in the survey by completing a verbal questionnaire (consisted of sociodemographics, past medical history, sexual history, and self-estimated scales). The results showed that 1,280 men completed the survey. Based on the CP/CPPS definition, a total of 801 men were diagnosed as having CP/CPPS. Men with CP/CPPS reported higher scores of NIH-CPSI and lower scores of IIEF-5 than men without CP/CPPS. NIH-CPSI scores were significantly negatively correlated with IIEF-5 scores. The total scores of NIH-CPSI were significantly more strongly correlated with question 5 than other questions of IIEF-5. The total scores of IIEF-5 were significantly more strongly correlated with pain symptoms scores of NIH-CPSI. Strongest correlation was found between QoL impact and question 5 of IIEF-5. The findings suggested that NIH-CPSI scores were significantly negatively correlated with IIEF-5 scores. Strongest correlation was found between QoL impact and question 5 of IIEF-5.

To compare the PROMIS Physical Function Computer Adaptive Test (PROMIS PF CAT) to commonly used traditional PF measures for the evaluation of patients with proximal humerus fractures. Prospective. Two Level I trauma centers. Forty-seven patients older than 60 years with displaced proximal humerus fractures treated between 2006 and 2009. Evaluation included completion of the PROMIS PF CAT, the Constant Shoulder Score, the Disabilities of the Arm, Shoulder, and Hand (DASH) and the Short Musculoskeletal Functional Assessment (SMFA). Observed correlations among the administered PF outcome measures. On average, patients responded to 86 outcome-related items for this study: 4 for the PROMIS PF CAT (range: 4-8 items), 6 for the Constant Shoulder Score, 30 for the DASH, and 46 for the SMFA. Time to complete the PROMIS PF CAT (median completion time = 98 seconds) was significantly less than that for the DASH (median completion time = 336 seconds, P < 0.001) and for the SMFA (median completion time = 482 seconds, P < 0.001). PROMIS PF CAT scores correlated statistically significantly and were of moderate-to-high magnitude with all other PF outcome measure scores administered. This study suggests using the PROMIS PF CAT as a sole PF outcome measure can yield an assessment of upper extremity function similar to those provided by traditional PF measures, while substantially reducing patient assessment time.

This article reports the first behavioral genetic study of relationships between alexithymia and four styles of humor: affiliative, self-enhancing, self-defeating, and aggressive. A total of 509 MZ pairs and 264 DZ pairs of twins completed the Toronto Alexithymia Scale-20 (TAS-20) and the Humor Styles Questionnaire (HSQ). Consistent with our predictions, alexithymia correlated negatively with affiliative and self-enhancing humor and positively with self-defeating and aggressive humor. All but one of the 16 phenotypic correlations that we report are significant at the 0.01 level. Also consistent with our predictions, the phenotypic correlations between alexithymia and humor styles were primarily attributable to correlated genetic factors and to a lesser extent to correlated non-shared environmental factors. Correlated shared environmental factors had no significant effect. Implications and limitations of this study are discussed.

The purpose of this study was to evaluate whether physical activities reduce the risk of cognitive decline in community-dwelling elderly. We investigated correlations between cognitive functions at baseline and physical activities, correlations between cognitive functions at baseline and cognitive decline over 4 years, as well as correlations between physical activity at baseline and cognitive decline over 4 years. At baseline, 2,431 community-dwelling elderly completed the cognitive screening by telephone (TICS-J), and answered the questionnaires about physical activities. Of these, 1,040 subjects again completed the TICS-J over 4 years. Physical activities contained moving ability, walking frequency, walking speed, the exercise frequency. At baseline, 870 elderly (age 75.87±4.96 (mean±SD) years, duration of education 11.05±2.41) showed normal cognitive functions and 170 (79.19±6.22, 9.61±2.23) showed cognitive impairment. The total TICS-J score was significantly higher in cognitive normal subjects compared with that of cognitive impaired subjects (36.02±1.89, 30.19±2.25, respectively, p<0.001). Logistic regression analyses showed that moving ability significantly reduced the risk of cognitive impairment in an unadjusted model, and walking speed also reduced the risk of cognitive impairment at baseline even in an adjusted model. Cognitive function at baseline might be a predictor of cognitive function over 4 years. The longitudinal study revealed that walking speed and exercise frequency significantly correlate with maintenance of cognitive function over 4 years. This study provides that physical activities, especially walking speed have significant correlation with cognitive function.

The purpose of this study was to translate the Oxford hip score (OHS) into Turkish and to evaluate the psychometric properties by testing the internal consistency, reproducibility, construct validity, and responsiveness in patients with hip osteoarthritis (OA). Oxford hip score was translated and culturally adapted according to the guidelines in the literature. Seventy patients (mean age 61.45 ± 9.29 years) with hip osteoarthritis participated in the study. Patients completed the Turkish Oxford hip score (OHS-TR), the Short-Form 36 (SF-36), and Western Ontario and McMaster Universities Index (WOMAC). Internal consistency was tested using Cronbach's α coefficient. Patients completed OHS-TR questionnaire twice in 7 days for determining the reproducibility. Correlation between the total results of both tests was determined by the Pearson correlation coefficient and intraclass correlation coefficient (ICC). Validity was assessed by calculating the Pearson correlation coefficient between the OHS-TR and WOMAC and SF-36 scores. Floor and ceiling effects were analyzed. The internal consistency was high (Cronbach's α 0.93). The construct validity showed a significant correlation between the OHS-TR and WOMAC and related SF-36 domains (p < 0.001). The ICC's ranged between 0.80 and 0.99. There was no floor or ceiling effect in total OHS-TR score. The OHS-TR questionnaire is valid, reliable, and responsive for the Turkish-speaking patients with hip OA.

Exploratory Metabolomic Analyses Reveal Compounds Correlated with Lutein Concentration in Frontal Cortex, Hippocampus, and Occipital Cortex of Human Infant Brain

Lutein is a dietary carotenoid well known for its role as an antioxidant in the macula, and recent reports implicate a role for lutein in cognitive function. Lutein is the dominant carotenoid in both pediatric and geriatric brain tissue. In addition, cognitive function in older adults correlated with macular and postmortem brain lutein concentrations. Furthermore, lutein was found to preferentially accumulate in the infant brain in comparison to other carotenoids that are predominant in diet. While lutein is consistently related to cognitive function, the mechanisms by which lutein may influence cognition are not clear. In an effort to identify potential mechanisms through which lutein might influence neurodevelopment, an exploratory study relating metabolite signatures and lutein was completed. Post-mortem metabolomic analyses were performed on human infant brain tissues in three regions important for learning and memory: the frontal cortex, hippocampus, and occipital cortex. Metabolomic profiles were compared to lutein concentration, and correlations were identified and reported here. A total of 1276 correlations were carried out across all brain regions. Of 427 metabolites analyzed, 257 were metabolites of known identity. Unidentified metabolite correlations (510) were excluded. In addition, moderate correlations with xenobiotic relationships (2) or those driven by single outliers (3) were excluded from further study. Lutein concentrations correlated with lipid pathway metabolites, energy pathway metabolites, brain osmolytes, amino acid neurotransmitters, and the antioxidant homocarnosine. These correlations were often brain region—specific. Revealing relationships between lutein and metabolic pathways may help identify potential candidates on which to complete further analyses and may shed light on important roles of lutein in the human brain during development.

Motivation is an important psychological concept in academic learning. Subjects performed jigsaw puzzle and square puzzle sessions (as difficulty variant task) and 80%, 50%, and 20% completion sessions (as completion variant task). After square puzzle or 20% completion sessions, subjective motivation decreased. Although baseline scores on an academic motivation scale were negatively correlated with changes in subjective motivation for the square puzzle session, a positive correlation was observed for the 20% completion session. These suggest that while continual completion of facile task trials may support the motivation of college students with lower academic motivation, attempting difficult task trials may sustain that of those with higher academic motivation.

Flooding is a major threat to agricultural production. Most studies have focused on the lower water storage limit in rice fields, whereas few studies have examined the upper water storage limit. This study aimed to explore the effect of waterlogging at the rice tillering stage on rice growth and yield. The early-ripening late japonica variety Yangjing 4227 was selected for this study. The treatments included different submergence depths (submergence depth/plant height: 1/2 (waist submergence), 2/3 (neck submergence), and 1/1 (complete submergence)) and durations (1, 3, and 5 d). The control group was treated with the conventional alternation of drying and wetting. The effects of waterlogging at the tillering stage on root characteristics, dry matter production, nitrogen and phosphorus accumulation, yield, yield components, and 1-aminocyclopropane-1-carboxylic acid synthase (ACS) gene expression were explored. Compared with the control group, the 1/1 group showed significant increases in yield, seed-setting rate, photosynthetically efficient leaf area, and OS-ACS3 gene expression after 1 d of submergence. The grain number per panicle, dry weight of the aboveground and belowground parts, and number of adventitious roots also increased. Correlation analysis revealed a significant positive correlation between the panicle number and nitrogen content; however, no significant correlation was found for phosphorus content. If a decrease in rice yield of less than 10% is acceptable, half, 2/3, and complete submergence of the plants can be performed at the tillering stage for 1-3 d; this treatment will increase the space available for rice field water management/control and will improve rainfall resource utilization.

Hallucinations and delusions that complicate Parkinson's disease (PD) could lead to nursing home placement and are linked to increased mortality. Cognitive impairments are typically associated with the presence of hallucinations but there are no data regarding whether such a relationship exists with delusions. We hypothesized that hallucinations would be associated with executive and visuospatial disturbance. An exploratory examination of cognitive correlates of delusions was also completed to address the question of whether they differ from hallucinations. 144 PD subjects completed a neuropsychological battery to assess cognition and the SAPS to examine psychosis. Correlational analyses assessed associations between hallucinations and delusions with cognitive domains. 48 subjects (33%) reported psychotic symptoms: 25 (17%) experienced hallucinations without delusions, 23 (16%) had symptoms dominated by delusions. Severity and/or number of hallucination subtypes were significantly correlated with lower scores in language, memory, attention, executive functioning, and visuospatial ability. Correlations with delusions were non-significant. Tests of differences in the size of the correlations between groups revealed a significant relationship between language and visuospatial performance with hallucinations. Cognitive correlates of hallucinations and delusions appear to be different in PD, suggesting distinct pathogenic mechanisms and possibly anatomical substrates. Hence, delusions may not share the same associations with dementia as hallucinations. Since this is a new finding, further studies will be needed to confirm our results.

Background Completion of secondary education is important for individuals’ future health and health behaviour. The fundamental purpose of this study is to investigate the variation and clustering of school completion in families and neighbourhoods. Secondly, we aim to examine the impact of individuals’ family structure and neighbourhood of residence and examine to what extent parental education level moderates these associations. Methods Longitudinal register data for 30% of the entire Norwegian population aged 21–27 years in 2010 (N = 107,003) was extracted from Statistic Norway´s event database. Three-level logistic regression models, which incorporated individual, family, and neighbourhood contextual factors, were applied to estimate the family and neighbourhood general contextual effects and detect possible educational differences in the impact of family structure and urban place of residence in school completion. Results Completion rates were significantly higher within families with higher education level (79% in tertiary educated families vs. 61% and 48% in secondary and primary educated families respectively) and were strongly correlated within families (ICC = 39.6) and neighbourhoods (ICC = 5.7). Several structural factors at the family level negatively associated with school completion (e.g., family disruption, large family size, and young maternal age) were more prevalent and displayed more negative impact among primary educated individuals. Urban residence was associated with school completion, but only among the tertiary educated. Conclusions Investment in the resources in the individuals’ immediate surroundings, including family and neighbourhood, may address a substantial portion of the social inequalities in the completion of upper secondary education. The high intra-familial correlation in school completion suggests that public health policies and future research should acknowledge family environments in order to improve secondary education completion rates among young people within lower educated families.

To examine correlates of HPV vaccination uptake in a nationally representative sample of 18-26-year-old adults. Young adults aged 18-26 years were identified from the 2014 and 2015 National Health Interview Survey (n = 7588). Survey-weighted multivariable logistic regression models estimated sociodemographic factors associated with HPV vaccine initiation (≥1 dose) and completion (≥3 doses). Approximately 27% of study participants had initiated the HPV vaccine and 16% had completed the HPV vaccine. Participants were less likely to initiate the vaccine if they were men [(adjusted odds ratio) 0.19; (95% confidence interval) 0.16-0.23], had a high school diploma (0.40; 0.31-0.52) or less (0.46; 0.32-0.64) vs. college graduates, and were born outside the United States (0.52; 0.40-0.69). But, participants were more likely to initiate the HPV vaccine if they visited the doctor's office 1-5 times (2.09; 1.56-2.81), or ≥ 6 times (1.86; 1.48-2.34) within the last 12 months vs. no visits. Odds of completing HPV vaccine uptake followed the same pattern as initiation. And after stratifying the study population by gender and foreign-born status, these variables remained statistically significant. In our nationally representative study, only one out of six 18-26 year olds completed the required vaccine doses. Men, individuals with high school or less education, and those born outside the United States were less likely to initiate and complete the HPV vaccination. Our findings suggest that it may be useful to develop targeted interventions to promote HPV vaccination among those in the catch-up age range.

We developed a Self-Regulation Measure for Computer-based learning (SRMC) tailored toward medical students, by modifying Zimmerman’s Self-Regulated Learning Interview Schedule (SRLIS) for K-12 learners. The SRMC’s reliability and validity were examined in 2 studies. In Study 1, 109 first-year medical students were asked to complete the SRMC. Bivariate correlation analysis results indicated that the SRMC scores had a moderate degree of correlation with student achievement in a teacher-developed test. In Study 2, 58 third-year clerkship students completed the SRMC. Regression analysis results indicated that the frequency of medical students’ usage of self-regulation strategies was associated with their general clinical knowledge measured by a nationally standardized licensing exam. These two studies provided evidence for the reliability and concurrent validity of the SRMC to assess medical students’ self-regulation as aptitude. Future work should provide evidence to guide and improve instructional design as well as inform educational policy. PMID:20872071

To develop measures of 3 threat orientations that affect responses to health behavior messages. In Study 1, college students (N = 47) completed items assessing threat orientations and health behaviors. In Study 2, college students and community adults (N = 110) completed the threat orientation items and measures of convergent and discriminant validity. In Study 1, the control-based, denial-based, and heightened-sensitivity-based threat orientation scales demonstrated good internal consistency and correlated with engagement in health behaviors. In Study 2, the convergent and discriminant validity of the 3 measures was established. The 3 scales have good internal reliability and construct validity.

2013-04-01

Measures of mood states and post-traumatic stress (PTS) symptoms are commonplace in many studies. However, the conventional application of these measures conjointly raises questions whether they actually correlate, and whether mood states have a meaningful role in predicting PTS symptoms. This study aimed to assess the degree to which the Brunel Mood Scale (BRUMS) and the Impact of Event Scale-Revised (IES-R) would be useful in detecting adverse psychological experiences (e.g., PTS). A sample of South African Navy sailors (N = 103) completed the BRUMS during demobilization after a traumatic deployment, and 6 weeks later completed a repeat BRUMS and the IES-R. Significant correlations were found between some BRUMS and IES-R subscales, but the lack of other subscale correlations indicates that the two measures probably tap different expressions of psychological distress following exposure to adverse events. Greater mood distress correlated with more severe PTS. A BRUMS total mood distress score cutoff of ≥24 gave a sensitivity of 100% and specificity of 79% for severe PTS 6 weeks later. Using a BRUMS score of ≥24 at demobilization to assess for possible elevated PTS response later could be useful in the screening of large groups of people.

The study aims to test the reliability and validity of the Estonian version of the Swedish universities Scales of Personality (SSP), and to characterize the position of the SSP-measured traits within the basic personality dimensions of the five-factor model. A total of 529 participants completed the Estonian version of the SSP. A subsample of 197 persons completed the SSP together with the Revised NEO Personality Inventory (NEO-PI-R). The internal consistency of the SSP scales was satisfactory. Principal component analysis yielded three factors representing neuroticism, aggression and disinhibition. The factor solution obtained in the Estonian sample was similar to the original SSP study in the Swedish normative sample. NEO-PI-R Neuroticism had highest correlations with SSP neuroticism factor scales. Extraversion had strongest relationship with adventure seeking and low detachment. Agreeableness correlated positively with SSP social desirability and negatively to aggression-irritability scales. Conscientiousness facet Deliberation correlated with Impulsiveness. The Estonian SSP showed acceptable reliability and validity, which confirms that SSP is applicable in different social and cultural background. The SSP measures traits that correspond to the major personality models. The SSP characterizes three broad dimensions of personality, namely neuroticism, disinhibition and aggression, which are useful in assessment of personality correlates of mental disorders.

Patients with amnesia resulting from alcoholic Korsakoff syndrome and elderly control patients studied a list of words in two typographies (typed and handwritten) and then received a word-fragment completion test (e.g., -ys-e-y for mystery) in which the test cues also varied in typography. Unlike the elderly control patients, the amnesic patients did not show greater priming effect when the typography at test matched that at study. The amount of typography-dependent priming was positively correlated with the score on the Wechsler Memory Scale. These results suggest that the effects of typography change on repetition priming in word-fragment completion reflect explicit recollection, and that the representation that supports repetition priming effects observed with amnesic subjects in the word-fragment completion task does not code typography information.

The aim of this study was to evaluate the impact of computer-assisted learning on first-year dental students' waxing abilities and self-evaluation skills. Additionally, this study sought to determine how well digital evaluation software performed compared to faculty grading with respect to students' technical scores on a practical competency examination. First-year students at one U.S. dental school were assigned to one of three groups: control (n=40), E4D Compare (n=20), and Sirona prepCheck (n=19). Students in the control group were taught by traditional teaching methodologies, and the technology-assisted groups received both traditional training and supplementary feedback from the corresponding digital system. Five outcomes were measured: visual assessment score, self-evaluation score, and digital assessment scores at 0.25 mm, 0.30 mm, and 0.35 mm tolerance. The scores from visual assessment and self-evaluation were examined for differences among groups using the Kruskal-Wallis test. Correlation between the visual assessment and digital scores was measured using Pearson and Spearman rank correlation coefficients. At completion of the course, students were asked to complete a survey on the use of these digital technologies. All 79 students in the first-year class participated in the study, for a 100% response rate. The results showed that the visual assessment and self-evaluation scores did not differ among groups (p>0.05). Overall correlations between visual and digital assessment scores were modest though statistically significant (5% level of significance). Analysis of survey responses completed by students in the technology groups showed that profiles for the two groups were similar and not favorable towards digital technology. The study concluded that technology-assisted training did not affect these students' waxing performance or self-evaluation skills and that visual scores given by faculty and digital assessment scores correlated moderately.

The aim of this study was to develop and validate an observer-based coding system for the characterization and completion of homework assignments during Behavioral Activation (BA). Existing measures of homework completion are generally unsophisticated, and there is no current measure of homework completion designed to capture the particularities of BA. The tested scale sought to capture the type of assignment, realm of functioning targeted, extent of completion, and assignment difficulty. Homework assignments were drawn from 12 (mean age = 48, 83% female) clients in two trials of a 10-session BA manual targeting treatment-resistant depression in primary care. The two coders demonstrated acceptable or better reliability on most codes, and unreliable codes were dropped from the proposed scale. In addition, correlations between homework completion and outcome were strong, providing some support for construct validity. Ultimately, this line of research aims to develop a user-friendly, reliable measure of BA homework completion that can be completed by a therapist during session.

The study reports the use of three biomarkers i.e. total arsenic in hair and nails, total arsenic in blood, and total arsenic in urine to identify or quantify arsenic exposure and concomitant health effects. The main source of arsenic was inorganic exposure through drinking water. The arsenic levels and the health effects were analyzed closely in a family having maximum symptoms of arsenic. Based on the result of this study it is reported that there exist a correlation between the clinically observable symptoms, the blood and urine arsenic level, and the arsenic intake through drinking water. An intensive study on the urinary arsenic levels was carried out in which the urine levels of arsenic and the urine sufficiency tests were performed. A composite picture of body burden of arsenic has been obtained by carrying out a complete biochemical analysis of a maximum affected family. This confirms pronounced chronic exposure of the arsenic to these people. A combined correlation study on the arsenic levels measured in whole blood, urine, hair, nails and age present a remarkable outcome. Accordingly, the arsenic levels in blood are negatively correlated with the urine arsenic levels, which indicate either the inadequacy of the renal system in cleaning the blood arsenic or a continuous recirculation of the accumulated arsenic. This is an important conclusion about arsenical metabolism in humans. The study also raises the issues of the prospects of complete elimination of the accumulated arsenic and the reversibility of the health effects. Based on the work in Kourikasa village we report that there are very remote chances of complete purging of arsenic and thus reversibility of the health effects owing to various factors. The paper also discusses the various issues concerning the chronic arsenic poisoning management in the affected locations.

Optimizing the effectiveness of substance use disorder (SUD) treatment is critical in low-and middle-income countries (LMICs) with limited opportunities for SUD treatment. This is the first study to identify targets for interventions to improve the quality of SUD treatment in a LMIC. We explored correlates of three indicators of treatment quality (treatment engagement, completion and abstinence at treatment exit) using data from a SUD performance measurement system implemented in the Western Cape Province of South Africa. The sample included data from 1094 adult treatment episodes representing 53% of the treatment episodes in 2016. Using multivariate logistic regression analyses, we modeled socio-demographic, substance use and program correlates of treatment engagement, completion, and abstinence at treatment exit. Overall, 59% of patients completed treatment (48% of patients from outpatient services). Treatment completion was associated with greater likelihood of abstinence at treatment exit. Patients were more likely to complete treatment if they engaged in treatment, were older, and had more severe drug problems (characterized by daily drug use and heroin problems) and attended programs of shorter duration. Residential treatment was associated with greater likelihood of treatment engagement, completion, and abstinence at treatment exit. Improving rates of outpatient treatment completion will enhance the effectiveness of South Africa's SUD treatment system. Interventions that promote engagement in treatment, particularly among younger patients; reduce program length through referral to step-down continuing care; and ensure better matching of drug problem to treatment level and type could improve rates of treatment completion.

Object recognition occurs even when environmental information is incomplete. Illusory contours (ICs), in which a contour is perceived though the contour edges are incomplete, have been extensively studied as an example of such a visual completion phenomenon. Despite the neural activity in response to ICs in visual cortical areas from low (V1 and V2) to high (LOC: the lateral occipital cortex) levels, the details of the neural processing underlying IC perception are largely not clarified. For example, how do the visual areas function in IC perception and how do they interact to archive the coherent contour perception? IC perception involves the process of completing the local discrete contour edges (contour completion) and the process of representing the global completed contour information (contour representation). Here, functional magnetic resonance imaging was used to dissociate contour completion and contour representation by varying each in opposite directions. The results show that the neural activity was stronger to stimuli with more contour completion than to stimuli with more contour representation in V1 and V2, which was the reverse of that in the LOC. When inspecting the neural activity change across the visual pathway, the activation remained high for the stimuli with more contour completion and increased for the stimuli with more contour representation. These results suggest distinct neural correlates of contour completion and contour representation, and the possible collaboration between the two processes during IC perception, indicating a neural connection between the discrete retinal input and the coherent visual percept.

To examine correlations between cervical vertebral maturation stages (CVMs) and dental development stages, and cervical vertebral maturation (CVM) stage 6 and completion of root formation of mandibular third molar in Thai cleft patients. Lateral cephalograms of 366 cleft subjects aged 7-9 years were assessed for CVMs using Baccetti method. Calcication stages of all left mandibular teeth within each CVMs were assessed from panoramic films using Demirjian method. Spearman rank correlation coefficients comparing CVMs and teeth were 0.51-0.79 (p<0.001). Second molar had the highest and central incisor had the lowest correlations. In CVMs 6, 2.9% of third molars had completed root formation. However, only CVMs 6 could be predicted from third molar stage G that had a high likelihood ratio (30.94). Dental development was highly correlated with CVM in clefts. Third molar stage G could predict completed growth of mandible in individual patients, but it should be combined with other maturation indicators.

Cancer is the second cause of death in the world, and colon cancer is the third cause of death and is one of the most common cancers which will cure with early diagnosis, treatment and sufficient follow up. Assessing factors which affect this cancer is important for prolonging patient survival. Socioeconomic factors are among effective factors of cancer morbidity and mortality. Because mortality rates for colon cancers vary by socioeconomic characteristics, this study has been performed to recognize the relationship between socioeconomic factors with treatment and follow up of colon cancer. This was a cross-sectional, descriptive study for patients with colon cancer registered in Cancer Research Center of Shahid Beheshti University of Medical Sciences from April 2005 to November 2006. Patients were selected randomly, and the study was conducted using questionnaires filled by interviewing the patients via phone (if a patient was dead, the questions were asked from their family members). Data analysis was done using SPSS (version 19) software. The study was performed on 520 colon cancer patients with age range of 23-88 years. The mean age of the patients was 63 (S.D.=11.8) and the median age was 64. Two hundred thirty seven (45.4%) patients were female and 283 (54.4%) were male. Using Chi-square test, age<60 (p=0.002) and female gender (p=0.034) had a significant correlation with complete treatment and there was a significant relationship between complete follow up and age<60 (p=0.037), academic education (p=0.02) and having insurance (p=0.021). Multiple logistic regression tests were used to evaluate concurrent effects of variables on treatment and follow up. Correlated variables to complete treatment include: age<60 (p=0.001), and female gender The Odds Ratio (OR) of completing treatment for patients under 60 years of age versus patients above 60 years was 3.13 (95% C.I. 1.55 to 6.34), and the OR of completing treatment for women versus men was 1.91(95% C.I. 1.33 to 2.74). Correlated variables to follow up were academic education ( ) and having insurance . The OR of cancer follow up in illiterate patients versus college-educated patients was 0.45 (95% C.I. 0.24 to 0.82), and the OR of cancer follow up in patients without insurance versus patients with health was 0.46 (95% C.I. 0.21 to 0.98). Age is a correlated factor on completing colon cancer treatment. Women have more complete colon cancer treatment than men. Academic education and having insurance were the most important factors among socioeconomic factors observed in a five-year follow up after treatment. As the population of the old is increasing, executing effective interventions to improve treatment and follow up procedures for old patients is of prime importance. It seems that increasing the insurance contribution in follow up measures may lead to increase in the regular follow up and may affect patients' survival.

This study reports the first behavioral genetic investigation of the extent to which genetic and/or environmental factors contribute to the relationship between the Big Five personality factors and trait emotional intelligence. 213 pairs of adult monozygotic twins and 103 pairs of same-sex dizygotic twins completed the NEO-PI-R and the Trait Emotional Intelligence Questionnaire (TEIQue). Replicating previous non-twin studies, many significant phenotypic correlations were found between the Big Five factors - especially Neuroticism, Extraversion, and Conscientiousness - and the facets, factors, and global scores derived from the TEIQue. Bivariate behavioral genetic model-fitting analyses revealed that these phenotypic correlations were primarily attributable to correlated genetic factors and secondarily to correlated non-shared environmental factors. The results support the feasibility of incorporating EI as a trait within existing personality taxonomies.

In 2007, the Centers for Medicare & Medicaid Services (CMS) instituted a star rating system using performance outcome measures to assess Medicare Advantage Prescription Drug (MAPD) and Prescription Drug Plan (PDP) providers. To assess the relationship between 2 performance outcome measures for Medicare insurance providers, comprehensive medication reviews (CMRs), and high-risk medication use. This cross-sectional study included Medicare Part C and Part D performance data from the 2014 and 2015 calendar years. Performance data were downloaded per Medicare contract from the CMS. We matched Medicare insurance provider performance data with the enrollment data of each contract. Mann Whitney U and Spearman rho tests and a hierarchical linear regression model assessed the relationship between provider characteristics, high-risk medication use, and CMR completion rate outcome measures. In 2014, an inverse correlation between CMR completion rate and high-risk medication use was identified among MAPD plan providers. This relationship was further strengthened in 2015. No correlation was detected between the CMR completion rate and high-risk medication use among PDP plan providers in either year. A multivariate regression found an inverse association with high-risk medication use among MAPD plan providers in comparison with PDP plan providers in 2014 (beta = -0.358, P < 0.001) and 2015 (beta = -0.350, P < 0.001), the CMR completion rate in 2015 (beta = -0.221, P < 0.001), and enrollee population size in 2015 (beta = -0.203, P = 0.001). This study found that MAPD plan providers and higher CMR completion rates were associated with lower use of high-risk medications among beneficiaries. No outside funding supported this study. Silva Almodovar reports a fellowship funded by SinfoniaRx, Tucson, Arizona, during the time of this study. The other authors have nothing to disclose.

2015-01-01

Adsorption-desorption of the herbicide bispyribac-sodium was studied in four Indian soil types. Bispyribac-sodium was poorly adsorbed in the four soils and adsorption decreased with an increase in the herbicide concentration in solution. Freundlich adsorption coefficient (Kf) values for bispyribac-sodium ranged between 0.37 and 0.87. Slope (1/n) values varied from 0.2 to 0.31 suggesting that bispyribac-sodium adsorption was highly dependent on its initial concentration in solution. Bispyribac-sodium adsorption showed a positive correlation with soil pH (r = 0.809) and clay content (r = 0.699) while no correlation was observed with the organic carbon (r = 0.063) content. Sorbed herbicide was completely desorbed during a single desorption step suggesting that the herbicide was bound by weak adsorptive forces. Leaching studies of herbicide in soil 1 packed column indicated complete loss of soil applied herbicide under a simulated rainfall equivalent to 162 mm.

The development of myopia and growth of the eye, occur at a time when body stature is increasing. To investigate the relationship of lifestyle and body growth with axial elongation and myopia development among schoolchildren aged 7 to 9 years. Prospective study. Children in elementary schools without serious eye disorders were invited to participate. We measured cycloplegic refraction, corneal curvature, intraocular pressure, axial length, body height, and weight. Questionnaires about the children's daily lifestyles, family members' myopia and parents' socio-demographic status were completed. The children were followed up every 6 months in a 3-year period. Bivariate correlations, simple and multiple regression. Eighty-eight children participated in this study. Forty-eight were myopic at the beginning of the study, and their myopia correlated with longer axial length and parental myopia (P = 0.015, 0.012). Sixty-five children (74%) completed the study, and the rates of change per year were -0.43 ± 0.58 (mean + standard deviation) diopters in spherical equivalence, 0.32 ± 0.25 mm in axial length (AL), 5.73 ± 2.71 cm in body height, and 3.84 ± 2.23 kg in weight. The axial length change was positively correlated with the height change (P < 0.001). The myopia shift was correlated to axial length change (P = 0.000) but not correlated to height change. Using multiple regression test, near work was the only significant risk factor for myopia progression (P = 0.022). Our study showed that body height increment was correlated to axial length elongation but not to myopia shift in children aged 7-9 years. Genetic factors such as parental myopia and body height had a possible influence on myopia development, and the environment factor as near work intensity was related to myopia progression.

Numerous studies have examined the effects that body composition has on performance in football, soccer, and ice hockey; yet, there are no similar studies examining this relationship in men's lacrosse. The purpose of the study was to examine the physiological profiles and the relationship between body composition and performance in aerobic and anaerobic tests. Fifty-four (19.63 ± 1.21 years; 178.53 ± 6.17 cm; 81.66 ± 14.96 kg) Division III intercollegiate athletes participated. Performance tests, including a 1 repetition maximum power clean (PC), body weight (lbs), bench press repetitions, parallel bar triceps dips to fatigue (DR), two 300-yard shuttles, and a 1-mile run (MT), were completed after the completion of fall preseason practices. Body composition was estimated using air-displacement plethysmography. Correlation coefficients determined relationships between percent body fat (%BF), fat-free mass (FFM), and testing variables. Increased %BF was negatively correlated to DR (r = -0.36, p = 0.01) whereas positively correlated to each 300-yard shuttle time (T1 and T2), total 300-yard shuttle time (TT), and MT (r = 0.64, p = 0.00; r = 0.68, p = 0.00; r = 0.69, p = 0.00; and r = 0.44, p = 0.00, respectively). Increased FFM was positively correlated with PC (r = 0.58, p = 0.00) yet not correlated (p ≥ 0.05) with other variables. Results indicated that increased %BF might be a detriment to the repetitive anaerobic performance and aerobic capacity vital to on-field lacrosse performance. Body composition also demonstrated a significant relationship to moving internal vs. external resistances.

Functional magnetic resonance imaging (fMRI) is a technique that is sensitive to correlates of neuronal activity. The application of fMRI to measure functional connectivity of related brain regions across hemispheres (e.g. left and right motor cortices) has great potential for revealing fundamental physiological brain processes. Primarily, functional connectivity has been characterized by linear correlations in resting-state data, which may not provide a complete description of its temporal properties. In this work, we broaden the measure of functional connectivity to study not only linear correlations, but also those arising from deterministic, non-linear dynamics. Here the delta-epsilon approach is extended and applied to fMRI time series. The method of delays is used to reconstruct the joint system defined by a reference pixel and a candidate pixel. The crux of this technique relies on determining whether the candidate pixel provides additional information concerning the time evolution of the reference. As in many correlation-based connectivity studies, we fix the reference pixel. Every brain location is then used as a candidate pixel to estimate the spatial pattern of deterministic coupling with the reference. Our results indicate that measured connectivity is often emphasized in the motor cortex contra-lateral to the reference pixel, demonstrating the suitability of this approach for functional connectivity studies. In addition, discrepancies with traditional correlation analysis provide initial evidence for non-linear dynamical properties of resting-state fMRI data. Consequently, the non-linear characterization provided from our approach may provide a more complete description of the underlying physiology and brain function measured by this type of data.

We evaluated the accuracy of a newly developed self-completed Drinks Diary in care home residents and compared it with direct observation and fluid intake charts. Observational study. Residential care homes in Norfolk, UK. 22 elderly people (18 women, mean age 86.6 years SD 8.6, 12 with MMSE scores <27). Participants recorded their own drinks intake over 24 hours using the Drinks Diary while care staff used the homes' usual fluid intake chart to record drinks intake. These records were compared with drinks intake assessed by researcher direct observation (reference method), during waking hours (6am to 10pm), while drinks taken from 10pm to 6am were self-reported and checked with staff. Drinks intake assessed by the Drinks Diary was highly correlated with researcher direct observation (Pearson correlation coefficient r=0.93, p<0.001, mean difference -163ml/day) while few staff-completed fluid charts were returned and correlation was low (r=0.122, p=0.818, mean difference 702ml/day). The Drinks Diary classified 19 of 22 participants correctly as drinking enough or not using both the European Food Safety Authority and US recommendations. The Drinks Diary estimate of drinks intake was comparable with direct observation and more accurate (and reliably completed) than staff records. The Drinks Diary can provide a reliable estimate of drinks intake in elderly care home residents physically and cognitively able to complete it. It may be useful for researchers, care staff and practitioners needing to monitor drinks intake of elderly people, to help them avoid dehydration.

We present a measurement of baryon acoustic oscillations (BAO) in the cross-correlation of quasars with the Lyα-forest flux-transmission at a mean redshift z = 2.40. The measurement uses the complete SDSS-III data sample: 168,889 forests and 234,367 quasars from the SDSS Data Release DR12. In addition to the statistical improvement on our previous study using DR11, we have implemented numerous improvements at the analysis level allowing a more accurate measurement of this cross-correlation. We also developed the first simulations of the cross-correlation allowing us to test different aspects of our data analysis and to search for potential systematic errors inmore » the determination of the BAO peak position. We measure the two ratios D H(z = 2.40)=r d = 9.01 ± 0.36 and D M(z = 2.40)=r d = 35.7 ±1.7, where the errors include marginalization over the non-linear velocity of quasars and the metal - quasar cross-correlation contribution, among other effects. These results are within 1.8σ of the prediction of the flat-ΛCDM model describing the observed CMB anisotropies.We combine this study with the Lyα-forest auto-correlation function (Bautista et al. 2017), yielding D H(z = 2.40)=r d = 8.94 ± 0.22 and D M(z = 2.40)=r d = 36.6 ± 1.2, within 2.3σ of the same flat-ΛCDM model.« less

Objectives The objectives of the present study were to translate the English version of the Pregnancy Physical Activity Questionnaire into Chinese (PPAQ-C) and to determine its reliability and validity for use by pregnant Chinese women. Methods The study included 224 pregnant women during their first, second, or third trimesters of pregnancy who completed the PPAQ-C on their first visit and wore a uniaxial accelerometer (Lifecorder; Suzuken Co. Ltd) for 7 days. One week after the first visit, we collected the data from the uniaxial accelerometer records, and the women were asked to complete the PPAQ-C again. Results We used intraclass correlation coefficients to determine the reliability of the PPAQ-C. The intraclass correlation coefficients were 0.77 for total activity (light and above), 0.76 for sedentary activity, 0.75 for light activity, 0.59 for moderate activity, and 0.28 for vigorous activity. The intraclass correlation coefficients were 0.74 for "household and caregiving", 0.75 for "occupational" activities, and 0.34 for "sports/exercise". Validity between the PPAQ-C and accelerometer data was determined by Spearman correlation coefficients. Although there were no significant correlations for moderate activity (r = 0.19, P > 0.05) or vigorous activity (r = 0.15, P > 0.05), there were significant correlations for total activity [light and above; r = 0.35, P < 0.01)] and for light activity (r = 0.33, P < 0.01). Conclusions for Practice The PPAQ-C is reliable and moderately accurate for measuring physical activity in pregnant Chinese women.

To describe the detection of cortical areas and subcortical pathways involved in language observed in MRI activation studies and tractography in a 3T MRI scanner and to correlate the findings of these functional studies with direct intraoperative cortical and subcortical stimulation. We present a series of 14 patients with focal brain tumors adjacent to eloquent brain areas. All patients underwent neuropsychological evaluation before and after surgery. All patients underwent MRI examination including structural sequences, perfusion imaging, spectroscopy, functional imaging to determine activation of motor and language areas, and 3D tractography. All patients underwent cortical mapping through cortical and subcortical stimulation during the operation to resect the tumor. Postoperative follow-up studies were done 24 hours after surgery. The correlation of motor function and of the corticospinal tract determined by functional MRI and tractography with intraoperative mapping of cortical and subcortical motor areas was complete. The eloquent brain areas of language expression and reception were strongly correlated with intraoperative cortical mapping in all but two cases (a high grade infiltrating glioma and a low grade glioma located in the frontal lobe). 3D tractography identified the arcuate fasciculus, the lateral part of the superior longitudinal fasciculus, the subcallosal fasciculus, the inferior fronto-occipital fasciculus, and the optic radiations, which made it possible to mark the limits of the resection. The correlation with the subcortical mapping of the anatomic arrangement of the fasciculi with respect to the lesions was complete. The best treatment for brain tumors is maximum resection without associated deficits, so high quality functional studies are necessary for preoperative planning. Copyright © 2011 SERAM.

Objective. To demonstrate the feasibility of integrating the computer simulation, MyDispense, into a therapeutics course and to measure its effects on student perception and learning. Methods. We conducted a prospective study with an experimental phase and an implementation phase. In the first phase, students were randomized to complete a therapeutics case using MyDispense or traditional paper methods in class. In the second phase, all students completed two therapeutic cases using MyDispense in class with the option to complete four additional outside-of-class cases using MyDispense. Students completed pre- and post-tests in class and three surveys. Results. In the experimental phase, mean test scores increased from pre- to post-test for both MyDispense and traditional paper groups, but the difference between the groups was not statistically significant. Students in the traditional paper group reported statistically significant gains in confidence compared to the MyDispense group. In the implementation phase, mean test scores again increased, however, student perception of the use of MyDispense for therapeutics was negative. Completing the optional outside-of-class cases, however, was positively and significantly correlated with the midterm and final examination scores. Conclusion. Implementation of MyDispense in therapeutics may be feasible and has positive effects (eg, correlation with exam scores, capacity for immediate feedback, and potential for effective self-study). With short-term use and in the absence of assessment methods that also require seeking information from patients, students prefer to learn via traditional paper cases.

A correlated ab initio study of linear carbon-chain radicals CnH (n = 2-7)

NASA Technical Reports Server (NTRS)

Woon, D. E.; Loew, G. H. (Principal Investigator)

1995-01-01

Linear carbon-chain radicals CnH for n = 2-7 have been studied with correlation consistent valence and core-valence basis sets and the coupled cluster method RCCSD(T). Equilibrium structures, rotational constants, and dipole moments are reported and compared with available experimental data. The ground state of the even-n series changes from 2 sigma+ to 2 pi as the chain is extended. For C4H, the 2 sigma+ state was found to lie only 72 cm-1 below the 2 pi state in the estimated complete basis set limit for valence correlation. The C2H- and C3H- anions have also been characterized.

Gudjonsson, G H

1987-09-01

The purpose of this study is twofold: (1) to present a parallel form of the Gudjonsson Suggestibility Scale (GSS, Form 1); (2) to study test-retest reliabilities of interrogative suggestibility. Three groups of subjects were administered the two suggestibility scales in a counterbalanced order. Group 1 (28 normal subjects) and Group 2 (32 'forensic' patients) completed both scales within the same testing session, whereas Group 3 (30 'forensic' patients) completed the two scales between one week and eight months apart. All the correlations were highly significant, giving support for high 'temporal consistency' of interrogative suggestibility.

Cognitive changes following breast cancer treatment are likely multifactorial and have been linked to emotional factors, biophysiological factors, and fatigue, among others. Little is known about the contributions of modifiable factors such as stress, loneliness, and sleep quality. The purpose of this study was to explore the direct and indirect effects of perceived stress, loneliness, and sleep quality on perceived cognitive function (PCF) in breast cancer survivors (BCS) after chemotherapy completion. In this observational study, BCS 6 months to 10 years post chemotherapy were recruited from the community. We measured perceived stress, loneliness, sleep quality, anxiety, depression, fatigue, and PCF. Data analyses included descriptive statistics, correlations, and mediation analyses utilizing ordinary least square regression. Ninety women who were on average 3 years post chemotherapy completion participated in the study. Moderate to largely negative correlations were found between PCF and the psychosocial and sleep variables (r values ranged from - 0.31 to - 0.70, p values < .0009). Mediation analyses revealed that stress and daytime sleepiness both directly and indirectly impact PCF and that loneliness and sleep quality only have indirect effects (through anxiety and fatigue). Our findings suggest that perceived cognitive changes following breast cancer treatment are multifactorial and that higher stress levels, loneliness, daytime sleepiness, and poorer sleep quality are linked to worse perceived cognitive functioning. Also, stress, loneliness, and sleep quality may affect cognitive functioning through a shared psychobiological pathway. Interventions targeting stress, loneliness, and sleep quality may improve perceived cognitive functioning in breast cancer survivors.

Assessing and predicting memory performance in everyday life is a common assignment for neuropsychologists. However, most traditional neuropsychological tasks are not conceived to capture everyday memory performance. The Virtual Shop is a fully immersive task developed to assess memory in a more ecological way than traditional neuropsychological assessments. Two studies were undertaken to assess the feasibility of the Virtual Shop and to appraise its ecological and construct validity. In study 1, 20 younger and 19 older adults completed the Virtual Shop task to evaluate its level of difficulty and the way the participants interacted with the VR material. The construct validity was examined with the contrasted-group method, by comparing the performance of younger and older adults. In study 2, 35 individuals with subjective cognitive decline completed the Virtual Shop task. Performance was correlated with an existing questionnaire evaluating everyday memory in order to appraise its ecological validity. To add further support to its construct validity, performance was correlated with traditional episodic memory and executive tasks. All participants successfully completed the Virtual Shop. The task had an appropriate level of difficulty that helped differentiate younger and older adults, supporting the feasibility and construct validity of the task. The performance on the Virtual Shop was significantly and moderately correlated with the performance on the questionnaire and on the traditional memory and executive tasks. Results support the feasibility and both the ecological and construct validity of the Virtual Shop. Copyright © 2018 The Authors. Published by Elsevier B.V. All rights reserved.

Correlational study: illness representations and coping styles in caregivers for individuals with schizophrenia

PubMed Central

2013-01-01

Background Caring for individuals with schizophrenia can create distress for caregivers which can, in turn, have a harmful impact on patient progress. There could be a better understanding of the connections between caregivers’ representations of schizophrenia and coping styles. This study aims at exploring those connections. Methods This correlational descriptive study was conducted with 92 caregivers of individuals suffering from schizophrenia. The participants completed three questionnaires translated and validated in French: (a) a socio-demographic questionnaire, (b) the Illness Perception Questionnaire for Schizophrenia and (c) the Family Coping Questionnaire. Results Our results show that illness representations are slightly correlated with coping styles. More specifically, emotional representations are correlated to an emotion-focused coping style centred on coercion, avoidance and resignation. Conclusion Our results are coherent with the Commonsense Model of Self-Regulation of Health and Illness and should enable to develop new interventions for caregivers. PMID:23984848

This study designed and validated a questionnaire aimed at examining parental feeding styles to encourage healthy eating habits among Costa Rican adolescents. Adolescents (n=133; mean age 15.4 years), and their parents, participated in the study. The parents completed a parental feeding style questionnaire, and the adolescents completed 3-day food records. Confirmatory factor analyses suggest four distinct parental feeding styles, (a) verbal encouragement of healthy eating behaviors; (b) use of verbal sanctions to indirectly control the intake of healthy food; (c) direct control of access to and intake of food; and (d) use of food to regulate emotions and behavior. There were no correlations between dietary intake and the verbal encouragement of healthy eating behaviors, but there were significant negative correlations between (1) "the use of verbal sanctions to indirectly control the intake of healthy food", and the consumption of fruit and vegetable, of calcium, iron, vitamin B6 and folic acid intake, and (2) between the "direct control of access to and intake of food" and fast food consumption and total carbohydrates intake. The use of food to regulate emotions and behavior was positively correlated with high energy-dense food consumption. Stratification of the data shows significant differences by gender in the correlations between parental feeding style and dietary intake. Understanding parental feeding styles in a Latin American context is a first step in helping researchers develops culturally-appropriate parenting intervention/prevention strategies to encourage healthy eating behaviors during adolescence.

Etiologies of the Relationships Among Body Mass Index and Cold-Heat Patterns: A Twin Study.

Hur, Yoon-Mi; Jin, Hee-Jeong; Lee, Siwoo

2018-06-01

The phenotypic relationships between body mass index (BMI) and cold-heat patterns have been frequently reported, but the etiology of these relationships remains unknown. We previously demonstrated that the cold pattern (CP) and the heat pattern (HP) were heritable traits. In the present study, we explored underlying genetic and environmental structures of the relationships among BMI and the CP and the HP. Twins (N = 1,752) drawn from the South Korean twin registry completed a cold-heat pattern questionnaire via a telephone interview. The phenotypic correlations among the three phenotypes were moderate but significant. Cross-twin, cross-trait correlations among BMI and the CP and the HP were consistently greater in monozygotic than in dizygotic twins, suggesting the presence of genetic effects on the relationships between BMI and the two patterns. A trivariate Cholesky model was applied to the raw data. The results indicated that the phenotypic relationship between the HP and BMI was completely determined by common genetic influences, while the relationship between the CP and BMI was explained by both common genetic and common individual-specific environmental influences. The genetic correlation between the HP and the CP was not significant, suggesting that the two patterns may be genetically independent from each other. Genetic correlations were 0.31 between the HP and BMI, and -0.22 between the CP and BMI. The individual-specific environmental correlation was -0.22 between HP and CP, and between CP and BMI.

Learner-Centered Inquiry in Undergraduate Biology: Positive Relationships with Long-Term Student Achievement

PubMed Central

Ebert-May, Diane

2010-01-01

We determined short- and long-term correlates of a revised introductory biology curriculum on understanding of biology as a process of inquiry and learning of content. In the original curriculum students completed two traditional lecture-based introductory courses. In the revised curriculum students completed two new learner-centered, inquiry-based courses. The new courses differed significantly from those of the original curriculum through emphases on critical thinking, collaborative work, and/or inquiry-based activities. Assessments were administered to compare student understanding of the process of biological science and content knowledge in the two curricula. More seniors who completed the revised curriculum had high-level profiles on the Views About Science Survey for Biology compared with seniors who completed the original curriculum. Also as seniors, students who completed the revised curriculum scored higher on the standardized Biology Field Test. Our results showed that an intense inquiry-based learner-centered learning experience early in the biology curriculum was associated with long-term improvements in learning. We propose that students learned to learn science in the new courses which, in turn, influenced their learning in subsequent courses. Studies that determine causal effects of learner-centered inquiry-based approaches, rather than correlative relationships, are needed to test our proposed explanation. PMID:21123693

Footprints of electron correlation in strong-field double ionization of Kr close to the sequential-ionization regime

By combining kinematically complete measurements and a semiclassical Monte Carlo simulation we study the correlated-electron dynamics in the strong-field double ionization of Kr. Interestingly, we find that, as we step into the sequential-ionization regime, there are still signatures of correlation in the two-electron joint momentum spectrum and, more intriguingly, the scaling law of the high-energy tail is completely different from early predictions on the low-Z atom (He). These experimental observations are well reproduced by our generalized semiclassical model adapting a Green-Sellin-Zachor potential. It is revealed that the competition between the screening effect of inner-shell electrons and the Coulomb focusing of nuclei leads to a non-inverse-square central force, which twists the returned electron trajectory at the vicinity of the parent core and thus significantly increases the probability of hard recollisions between two electrons. Our results might have promising applications ranging from accurately retrieving atomic structures to simulating celestial phenomena in the laboratory.

To assess the validity and test-retest reliability of a Thai translation of the Migraine Disability Assessment (MIDAS) Questionnaire in Thai patients with migraine. Migraineurs from the Headache Clinic in Siriraj Hospital were recruited and asked to complete a 13-weeks diary and answered the Thai-MIDAS at once. Some participants were asked to provide the 2nd Thai-MIDAS in the next 2 weeks for test-retest reliability. Ninety-three patients had completed the 13-weeks diaries. Age range was 18-58 years with mean 37.69 +/- 9.60 years. All 5 items and the total score of Thai-MIDAS were moderately correlated with data from 13-weeks diary (Spearman's correlation coefficient = 0.32-0.62). The test-retest reliability of the total score of Thai-MIDAS in 30 patients demonstrated a highly reliable degree of intraclass correlation (ICC = 0.76, 95% CI 0.49-0.88). The present study reveals that the Thai-MIDAS has satisfactory validity and reliability in comparison with the original English MIDAS version.

The Sinus and Nasal Quality of Life Survey (SN-5) is a validated quality of life (QOL) questionnaire for chronic rhinosinusitis in patients age 2-12. Its utility in the cystic fibrosis (CF) has been studied, but not yet validated. The purpose of this study is to determine the effectiveness of the SN-5 for evaluation of sinonasal symptoms in the pediatric CF population. This retrospective study analyzed SN-5 surveys completed between 2012 and 2015 by pediatric CF patients and caregivers. Baseline and follow-up overall QOL scores and specific symptom scores were obtained from surveys completed in the three-year span. Non-parametric statistics were conducted to identify differences in survey data. A total of 165 patients completed baseline and follow-up surveys. The overall QOL of the patient cohort did not change over the duration of the study (p = 0.660). Thirty-seven patients indicated higher overall QOL, with all five symptom scores showing significant improvement. Analysis by age group showed that QOL was significantly correlated with all five symptoms for children ages 0-4. In patients 5-12 years, overall QOL was only correlated with sinus infection (r = -0.3090, p = 0.01). QOL was significantly correlated with sinus infection (r = -0.2903, p = 0.04) and allergy symptoms (r = -0.5644, p < 0.01) in patients >12 years of age. There remains a need for a validated CRS QOL tool for children with CF. Though the SN-5 has previously been described as a potential instrument, our data suggest that it may be more valuable in children ages 0-4. Copyright © 2017 Elsevier B.V. All rights reserved.

Patient-reported outcome measures (PROMs) have been gaining in popularity over the last decade. The Oxford Shoulder Score (OSS) is a well-established self-administered questionnaire for shoulder evaluation adapted for the English-speaking population. The aim of the present study was to develop a translation and a transcultural adaptation of the OSS and to assess its validity in native French-speaker patients with shoulder pain. The translation process was carried out following a translation/back-translation methodology by two translators. All patients completed the French OSS, the Subjective Shoulder Value (SSV), and the Constant score. Internal consistency was tested using Cronbach's α coefficient. Validity was assessed by calculating the Pearson correlation coefficient between the OSS and the Constant score and the SSV. One hundred forty-four patients suffering from degenerative or inflammatory diseases of the shoulder were included in this study. The average time required to complete the French OSS was 2min and 45s. Seventy patients were asked to complete the questionnaire twice (test/retest reliability). Internal consistency was high with Cronbach's α coefficient=0.93. The intraclass correlation coefficient was 0.91 (95% CI: 0.88-0.94) for test/retest reliability. The French OSS score was significantly correlated with the Constant-Murley score (r=0.73 and P<0.0001) and with the SSV (r=0.68 and P<0.0001). The present study shows that the French version of the OSS is reliable, valid, and reproducible. The sensitivity to change now needs to be evaluated. This score was adapted to the French-speaking population for the self-assessment of patients with degenerative or inflammatory disorders of the shoulder.

Fatigue, depression, anxiety, and executive dysfunction are associated with multiple sclerosis (MS) in adults. Existing research suggests similar problems in pediatric MS, but relationships between these variables have not been investigated. This study investigates the associations between executive functioning and fatigue, emotional functioning, age of onset, and disease duration in pediatric MS. Twenty-six MS or Clinically Isolated Syndrome (CIS) patients, ages 7 to 18, were evaluated through a multidisciplinary demyelinating diseases clinic. Participants completed neuropsychological screening including Verbal Fluency, Digit Span, and Trail-Making Test. Parents completed rating forms of behavioral, emotional, and executive functioning. Patients and parents completed questionnaires related to the patient's quality of life and fatigue. Pearson's correlation coefficients were calculated to investigate relationships between fatigue, emotional functioning, and executive functioning, as well as to examine correlations between parent and child reports of fatigue. Rates of parent-reported anxiety, depression, fatigue, and executive dysfunction varied widely. Means were below average on the Trail-Making Test and average on Verbal Fluency and Digit Span, though scores varied widely. Various fatigue and emotional functioning indices-but not age of onset or disease duration-significantly correlated with various performance-based measures of executive functioning. Results indicate pediatric MS is associated with some degree of fatigue, emotional difficulties, and executive dysfunction, the latter of which is associated with the two former. Notably, age of onset and disease duration did not significantly correlate with executive functioning. Results advance understanding of psychological and clinical variables related to neurocognitive outcomes in pediatric MS.

Brief communication: patient satisfaction with the use of tablet computers: a pilot study in two outpatient home dialysis clinics.

Electronic capture of patients' reports of their health is significant in clinical nephrology research because health-related quality of life (HRQOL) for patients with end-stage renal disease is compromised and assessment by patients of their HRQOL in practice is relatively uncommon. The purpose of this study was to evaluate patient satisfaction with and time involved in administering HRQOL and symptom assessment measures using tablet computers in two outpatient home dialysis clinics. A cross-sectional observational study design was employed. The study was conducted in two home dialysis clinics. Fifty-six patients participated in the study; 35 males (63%) and 21 females (37%) with a mean age of 66 ± 12 (36-90 years old) were included. Forty-nine participants were on peritoneal dialysis (87%), 6 on home hemodialysis (11%), and 1 on nocturnal home hemodialysis (2%). Measures included the Kidney Disease Quality of Life-36 (KDQOL-36), the Edmonton Symptom Assessment Scale (ESAS) and Participant's Level of Satisfaction in Using a Tablet Computer. Using a tablet computer, participants completed the three measures. Descriptive statistics and bivariate correlations were calculated. Participants' satisfaction with use of the tablet computer was high; 66% were "very satisfied", 7% "satisfied", 2% "slightly satisfied", and 18% "neutral". On the 7-point Likert-type scale, the mean satisfaction score was 5.11 (SD = 1.6). Mean time to complete the measures was: Level of Satisfaction 1.15 minutes (SD = 0.41), ESAS 2.55 minutes (SD = 1.04), and KDQOL 9.56 minutes (SD = 2.03); the mean time to complete all three instruments was 13.19 minutes (SD = 2.42). There were no significant correlations between level of satisfaction and age, gender, HRQOL, time taken to complete surveys, computer experience, or comfort with technology. Comfort with technology and computer experience were highly correlated, r = .7, p (one-tailed) < 0.01. Limitations include lack of generalizability because of a small self-selected sample of relatively healthy patients and a lack of psychometric testing on the measure of satisfaction. Participants were satisfied with the platform and the time involved for completion of instruments was modest. Routine use of HRQOL measures for clinical purposes may be facilitated through use of tablet computers.

To date, there has been little research on shared decision making and decisional outcomes in pediatric surgery. The objectives of this study were to describe the level of decisional conflict and decisional regret experienced by parents considering otoplasty for their children, and to determine if they are related to perceptions of shared decision making. Prospective cohort clinical study. Sixty-five consecutive parents of children who underwent surgical consultation for otoplasty were prospectively enrolled. Participants completed the Demographic Form, the Decisional Conflict Scale, and the Shared Decision-Making Questionnaire after the consultation visit. The consulting surgeons completed the physician version of the Shared Decision-Making Questionnaire. Six months after surgery, parents completed the Decisional Regret Scale. The median decisional conflict was 15.63; 21 (32.8%) parents scored 25 or above, a previously defined cutoff indicating clinically significant decisional conflict. Parent ratings of shared decision making and decisional conflict were significantly negatively correlated (P < 0.001); however, there was no significant correlation between physician ratings of shared decision making and parental decisional conflict. Significant decisional regret was reported in two (3.2%) participants. Decisional regret and parent and physician ratings of shared decision making were both significantly negatively correlated (P = 0.044 and P = 0.001, respectively). Decisional regret and decisional conflict scores were significantly positively correlated (P = 0.001). Parent and physician ratings of shared decision making were correlated (intraclass correlation = 0.625, P < 0.001). Many parents experienced significant decisional conflict when making decisions about their child's elective surgical treatment. Fewer parents experienced significant decisional regret after the procedure. Parents who perceived themselves as being more involved in the decision making process reported less decisional conflict and decisional regret. Parents and physicians had varied perceptions of the degree of shared decision making. Future research should develop interventions to increase parents' involvement in decision making and explore the influence of significant decisional conflict and decisional regret on health outcomes. 2b.

There is a poor association between the dentist's evaluation of denture quality and patients' satisfaction with their dentures. Possible differences between dental professionals and patients' expectations might help explain differences in outcome evaluations. This study compared scores given by a dentist, a dental technician and patients for their expectations before and their final evaluation after complete dentures treatment. Twenty completely edentulous patients, a prosthodontist and a dental technician provided scores for the expected aesthetic and functional results of their dentures based on a visual analogue scale at baseline. Post-treatment completion ratings were given after adjustments, by dentist and patients. The dental technician provided post-treatment completion ratings after completing the dentures. The patients had higher expectations than the dental technician and the dentist perceived for both aesthetic and function (P < 0.001). The patients also presented higher post-treatment completion ratings than the dental professionals perceived for final aesthetics (P = 0.016, Kendall's W = 0.207) and function (P = 0.002, Kendall's W = 0.303). Only the dentist presented a statistically significant difference between expectations (lower) and final (higher) outcomes for aesthetics (P = 0.017) and function (P = 0.003). There was no correlation between expectations and post-treatment completion ratings according to the patients' age. There was also no correlation between the patients' gender and expectation scores. Patients presented higher expectations regarding their dentures than dental professionals. The dentist believed that dentures would bring fewer benefits than patients did, but his perception of denture benefits post-treatment was significantly higher than his expectations.

VINEGAR AS AN ANTIMICROBIAL AGENT FOR CONTROL OF Candida spp. IN COMPLETE DENTURE WEARERS

The use of denture is known to increase the carriage of Candida in healthy patients, and the proliferation of Candida albicans strains can be associated with denture-induced stomatitis. The aim of this study was to evaluate the use of vinegar as an antimicrobial agent for control of Candida spp. in complete upper denture wearers. Fifty-five patients were submitted to a detailed clinical interview and oral clinical examination, and were instructed to keep their dentures immersed in a 10% vinegar solution (pH less than 3) overnight for 45 days. Before and after the experimental period, saliva samples were collected for detection of Candida, counting of cfu/mL and identification of species by phenotypical tests (germ tube formation, chlamidoconidia production, and carbohydrate fermentation and assimilation). The results were analyzed using Spearman's correlation and Student's t-test (p≤0.05). Candida yeasts were present in 87.3% of saliva samples before the treatment. A significant reduction was verified in CFU/mL counts of Candida after treatment. A positive correlation between Candida and denture stomatitis was verified, since the decrease of cfu/mL counts was correlated with a reduction in cases of denture stomatitis. Although it was not able to eliminate C. albicans, the immersion of the complete denture in 10% vinegar solution, during the night, reduced the amounts (cfu/mL) of Candida spp. in the saliva and the presence of denture stomatitis in the studied patients.

A number of case reports show various outcomes of premature closure of the ductus arteriosus in utero, including persistent pulmonary hypertension of the newborn and fetal or neonatal death; however, no study clarifies the clinical observations that are related to their prognoses. We aimed to clarify the prognostic factors of intrauterine ductal closure by a systematic literature review. Data sources We searched PubMed database (1975-2014) to identify case reports and studies on intrauterine closure of the ductus arteriosus, including maternal, fetal, and neonatal clinical information and their prognoses. We analysed the data of 116 patients from 39 articles. Of these, 12 (10.3%) died after birth or in utero. Fetal or neonatal death was significantly correlated with fetal hydrops (odds ratio=39.6, 95% confidence interval=4.6-47.8) and complete closure of the ductus arteriosus (odds ratio=5.5, 95% confidence interval=1.2-15.1). Persistent pulmonary hypertension was observed in 33 cases (28.4%), and was also correlated with fetal hydrops (odds ratio=4.2, 95% confidence interval=1.3-4.6) and complete closure of the ductus arteriosus (odds ratio=5.5, 95% confidence interval=1.6-6.0). Interestingly, maternal drug administration was not correlated with the risk of death and persistent pulmonary hypertension. Fetal hydrops and complete ductal closure are significant risk factors for both death and persistent pulmonary hypertension. Cardiac or neurological prognoses could be favourable if the patients overcome right heart failure during the perinatal period.

The correlation between thought-action fusion and religiosity in a normal sample.

PubMed

Rassin, E; Koster, E

2003-03-01

Thought-action fusion (TAF) refers to a set of two cognitive biases that are thought to contribute to the inflation of feelings of responsibility for one's own thoughts, and thus to the development of obsession. Therefore, insight into the origins of TAF is a clinically relevant research topic. The present study examined the association between religiosity and TAF. Undergraduate students (N=100) completed questionnaires concerning religion, TAF and obsessive-compulsive complaints. Results indicate that religiosity is, indeed, correlated with certain aspects of TAF. Furthermore, correlational patterns differed between Catholic and Protestant subsamples.

To facilitate large-scale assessment of a variety of cognitive abilities in clinical studies, we developed a self-administered online neuropsychological test battery: the Amsterdam Cognition Scan (ACS). The current studies evaluate in a group of adult cancer patients: test-retest reliability of the ACS and the influence of test setting (home or hospital), and the relationship between our online and a traditional test battery (concurrent validity). Test-retest reliability was studied in 96 cancer patients (57 female; M age  = 51.8 years) who completed the ACS twice. Intraclass correlation coefficients (ICCs) were used to assess consistency over time. The test setting was counterbalanced between home and hospital; influence on test performance was assessed by repeated measures analyses of variance. Concurrent validity was studied in 201 cancer patients (112 female; M age  = 53.5 years) who completed both the online and an equivalent traditional neuropsychological test battery. Spearman or Pearson correlations were used to assess consistency between online and traditional tests. ICCs of the online tests ranged from .29 to .76, with an ICC of .78 for the ACS total score. These correlations are generally comparable with the test-retest correlations of the traditional tests as reported in the literature. Correlating online and traditional test scores, we observed medium to large concurrent validity (r/ρ = .42 to .70; total score r = .78), except for a visuospatial memory test (ρ = .36). Correlations were affected-as expected-by design differences between online tests and their offline counterparts. Although development and optimization of the ACS is an ongoing process, and reliability can be optimized for several tests, our results indicate that it is a highly usable tool to obtain (online) measures of various cognitive abilities. The ACS is expected to facilitate efficient gathering of data on cognitive functioning in the near future.

Cruciate ligament rupture (CR) and associated osteoarthritis (OA) is a common condition in dogs. Dogs frequently develop a second contralateral CR. This study tested the hypothesis that the degree of stifle synovitis and cranial cruciate ligament (CrCL) matrix damage in dogs with CR is correlated with non-invasive diagnostic tests, including magnetic resonance (MR) imaging. We conducted a prospective cohort study of 29 client-owned dogs with an unstable stifle due to complete CR and stable contralateral stifle with partial CR. We evaluated correlation of stifle synovitis and CrCL fiber damage with diagnostic tests including bilateral stifle radiographs, 3.0 Tesla MR imaging, and bilateral stifle arthroscopy. Histologic grading and immunohistochemical staining for CD3+ T lymphocytes, TRAP+ activated macrophages and Factor VIII+ blood vessels in bilateral stifle synovial biopsies were also performed. Serum and synovial fluid concentrations of C-reactive protein (CRP) and carboxy-terminal telopeptide of type I collagen (ICTP), and synovial total nucleated cell count were determined. Synovitis was increased in complete CR stifles relative to partial CR stifles (P<0.0001), although total nucleated cell count in synovial fluid was increased in partial CR stifles (P<0.01). In partial CR stifles, we found that 3D Fast Spin Echo Cube CrCL signal intensity was correlated with histologic synovitis (SR = 0.50, P<0.01) and that radiographic OA was correlated with CrCL fiber damage assessed arthroscopically (SR = 0.61, P<0.001). Taken together, results of this study show that clinical diagnostic tests predict severity of stifle synovitis and cruciate ligament matrix damage in stable partial CR stifles. These data support use of client-owned dogs with unilateral complete CR and contralateral partial CR as a clinical trial model for investigation of disease-modifying therapy for partial CR.

The purpose of this study was to analyze the effectiveness of an online medical laboratory technician program in the academic preparation and development of laboratory professionals. A semi-quantitative comparative research design was used. Several factors were considered in this evaluation. Academic outcomes between online and campus medical laboratory technician (MLT) students was determined by comparing overall and categorical scores on certification exams as well as first time pass rate. Certification exam scores and first time pass rates were also compared to national norms when possible to do so. Demographic data, including age and experience were compared. Additionally, learning styles were assessed to determine if there was a correlation to overall GPA and MLT GPA and if learning styles could be used to predict successful completion of an online Associates of Applied Science. The research was conducted at an academic university located in the mountain west United States. Participants consisted of online and campus students enrolled in a Medical Laboratory Technician program that graduated with their Associate of Applied Science degree between the years 2007-2009. Results of these years were also compared to graduates from 2004-2006 in the same program. Certification performance and first time pass rates were the major outcomes measured. Age and experience were correlated. Online learning styles and GPA were also compared to successful degree completion. The researcher found no significant difference in certification performance with regard to total and categorical scores, and first time pass rates between campus and online MLT students. Online students were slightly older and had more experience working in a laboratory in some capacity. Correlation studies showed significant positive correlation between learning styles, GPA, and successful completion of an Associate of Applied Science degree. When registry scores were compared to the prior cohort of online students, some subcategories scores demonstrated a significant increase using Chi-squared analysis. The research demonstrated that the online MLT students studied were as academically prepared as their campus counterparts.

The purpose of this study was to compare pulmonary function in children with developmental coordination disorder (DCD) with children who are typically developing (TD), and also analyze possible gender differences in pulmonary function between these groups. The Movement ABC test was used to identify the movement coordination ability of children. Two hundred and fifty participants (90 children with DCD and 160 TD children) aged 9-10 years old completed this study. Using the KoKo spirometry, forced vital capacity (FVC) and forced expiratory volume in 1s (FEV(1.0)) were used to measure pulmonary function. The 800-m run was also conducted to assess cardiopulmonary fitness of children in the field. There was a significant difference in pulmonary function between TD children and those with DCD. The values of FVC and FEV(1.0) in TD children were significantly higher than in children with DCD. A significant, but low correlation (r = -0.220, p < .001) was found between total score on the MABC and FVC; similarly, a positive but low correlation (r = 0.252, p < .001) was found between total score on the MABC and the completion time of 800-m run. However, no significant correlation between FVC and the time of 800-m run was found (p > .05). Significant correlations between total score on the MABC and the completion time of the 800-m run (r = 0.352, p < .05) and between FVC and the time of 800-m run (r = -0.285, p < .05) were observed in girls with DCD but not boys with this condition. Based on the results of this study, pulmonary function in children with DCD was significantly lower than that of TD children. The field test, 800-m run, may not be a good indicator to distinguish aerobic ability between children with DCD and those who are TD. It is possible that poor pulmonary function in children with DCD is due to reduced physical activity in this population. Copyright © 2010 Elsevier Ltd. All rights reserved.

Normative data on the objective age of acquisition (AoA) for 286 Russian words are presented in this article. In addition, correlations between the objective AoA and subjective ratings, name agreement, picture name agreement, imageability, familiarity, word frequency, and word length are provided, as are correlations between the objective AoA and two measures of exemplar dominance (exemplar generation frequency and the number of times an exemplar was named first). The correlations between the aforementioned variables are generally consistent with the correlations reported in other normative studies. The objective AoA data are highly correlated with the subjective AoA ratings, whereas the correlations between the objective AoA and other psycholinguistic variables are moderate. The correlations between the objective AoA of Russian words and similar data for other languages are moderately high. The complete word norms may be downloaded from supplementary material.

Background: Brain–computer interface (BCI) devices are being investigated for their application in stroke rehabilitation, but little is known about how structural changes in the motor system relate to behavioral measures with the use of these systems. Objective: This study examined relationships among diffusion tensor imaging (DTI)-derived metrics and with behavioral changes in stroke patients with and without BCI training. Methods: Stroke patients (n = 19) with upper extremity motor impairment were assessed using Stroke Impact Scale (SIS), Action Research Arm Test (ARAT), Nine-Hole Peg Test (9-HPT), and DTI scans. Ten subjects completed four assessments over a control period during which no training was administered. Seventeen subjects, including eight who completed the control period, completed four assessments over an experimental period during which subjects received interventional BCI training. Fractional anisotropy (FA) values were extracted from each corticospinal tract (CST) and transcallosal motor fibers for each scan. Results: No significant group by time interactions were identified at the group level in DTI or behavioral measures. During the control period, increases in contralesional CST FA and in asymmetric FA (aFA) correlated with poorer scores on SIS and 9-HPT. During the experimental period (with BCI training), increases in contralesional CST FA were correlated with improvements in 9-HPT while increases in aFA correlated with improvements in ARAT but with worsening 9-HPT performance; changes in transcallosal motor fibers positively correlated with those in the contralesional CST. All correlations p < 0.05 corrected. Conclusion: These findings suggest that the integrity of the contralesional CST may be used to track individual behavioral changes observed with BCI training after stroke. PMID:27695404

Neural correlates of monocular and binocular depth cues based on natural images: a LORETA analysis.

PubMed

Fischmeister, Florian Ph S; Bauer, Herbert

2006-10-01

Functional imaging studies investigating perception of depth rely solely on one type of depth cue based on non-natural stimulus material. To overcome these limitations and to provide a more realistic and complete set of depth cues natural stereoscopic images were used in this study. Using slow cortical potentials and source localization we aimed to identify the neural correlates of monocular and binocular depth cues. This study confirms and extends functional imaging studies, showing that natural images provide a good, reliable, and more realistic alternative to artificial stimuli, and demonstrates the possibility to separate the processing of different depth cues.

During the presurgical evaluation of patients with medically intractable focal epilepsy, a variety of noninvasive studies are performed to localize the hypothetical epileptogenic zone and guide the resection. Magnetoencephalography (MEG) is becoming increasingly used in the clinical realm for this purpose. No investigators have previously reported on coregisteration of MEG clusters with postoperative resection cavities to evaluate whether complete "clusterectomy" (resection of the area associated with MEG clusters) was performed or to compare these findings with postoperative seizure-free outcomes. The authors retrospectively reviewed the charts and imaging studies of 65 patients undergoing MEG followed by resective epilepsy surgery from 2009 until 2012 at the Cleveland Clinic. Preoperative MEG studies were fused with postoperative MRI studies to evaluate whether clusters were within the resected area. These data were then correlated with postoperative seizure freedom. Sixty-five patients were included in this study. The average duration of follow-up was 13.9 months, the mean age at surgery was 23.1 years, and the mean duration of epilepsy was 13.7 years. In 30 patients, the main cluster was located completely within the resection cavity, in 28 it was completely outside the resection cavity, and in 7 it was partially within the resection cavity. Seventy-four percent of patients were seizure free at 12 months after surgery, and this rate decreased to 60% at 24 months. Improved likelihood of seizure freedom was seen with complete clusterectomy in patients with localization outside the temporal lobe (extra-temporal lobe epilepsy) (p = 0.04). In patients with preoperative MEG studies that show clusters in surgically accessible areas outside the temporal lobe, we suggest aggressive resection to improve the chances for seizure freedom. When the cluster is found within the temporal lobe, further diagnostic testing may be required to better localize the epileptogenic zone.

Incompressible boundary-layer stability analysis of LFC experimental data for sub-critical Mach numbers. M.S. Thesis

Berry, S. A.

1986-01-01

An incompressible boundary-layer stability analysis of Laminar Flow Control (LFC) experimental data was completed and the results are presented. This analysis was undertaken for three reasons: to study laminar boundary-layer stability on a modern swept LFC airfoil; to calculate incompressible design limits of linear stability theory as applied to a modern airfoil at high subsonic speeds; and to verify the use of linear stability theory as a design tool. The experimental data were taken from the slotted LFC experiment recently completed in the NASA Langley 8-Foot Transonic Pressure Tunnel. Linear stability theory was applied and the results were compared with transition data to arrive at correlated n-factors. Results of the analysis showed that for the configuration and cases studied, Tollmien-Schlichting (TS) amplification was the dominating disturbance influencing transition. For these cases, incompressible linear stability theory correlated with an n-factor for TS waves of approximately 10 at transition. The n-factor method correlated rather consistently to this value despite a number of non-ideal conditions which indicates the method is useful as a design tool for advanced laminar flow airfoils.

Anxiety symptoms are common in youth with autism spectrum disorders (ASD) and directly associated with symptom severity and functional impairment. Family accommodation occurs frequently among individuals with obsessive-compulsive and anxiety disorders; to date, no data exist on the nature and correlates of family accommodation in youth with ASD and anxiety, as well as its relationship to cognitive-behavioral therapy outcome. Forty children with ASD and a comorbid anxiety disorder participated. Clinicians administered measures of ASD and anxiety disorder caseness, anxiety symptom severity, and family accommodation; parents completed questionnaires assessing social responsiveness, internalizing and externalizing behaviors, and functional impairment. A subsample of youth (n = 24) completed a course of cognitive-behavioral therapy. Family accommodation was common and positively correlated with anxiety symptom severity, but not functional impairment, general internalizing symptoms, externalizing behavior, or social responsiveness. Family accommodation decreased following cognitive-behavioral therapy with decreases in family accommodation being associated with decreases in anxiety levels. Treatment responders reported lower family accommodation frequency and lower parent impact relative to non-responders. Clinical implications of this study in assessing and psychotherapeutically treating youth with ASD and comorbid anxiety are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

The purpose of this study was to examine the feasibility and validity of an Athletic Skills Track (AST) to assess fundamental movement skills among 6- to 12-year-old children in a physical education setting. Four hundred sixty-three Dutch children (211 girls, 252 boys) completed three tests: the Körperkoordinationstest für Kinder (KTK) and two Athletic Skills Tracks (AST-1, AST-2). The validity of AST-1 and AST-2 was examined by correlating the time (s) needed to complete the tracks and the KTK Motor Quotient (MQ). Overall, there was a low correlation between AST-1 and the KTK MQ (r = -0.474 (P < 0.01)) and a moderate correlation between AST-2 and the KTK MQ (r = -0.502 (P < 0.01)). When split up by age group the associations were much higher and ranged between r = -0.469 and r = -0.767), with the exception of the low correlation coefficient of the AST-2 in 7-year-olds. The results indicate that fundamental movement skills of 6- to 12-year-old children can be assessed with a quick, convenient and low-cost motor competence test in a physical education setting, i.e., an Athletic Skills Track. Future studies should further assess the reliability, discriminative ability and validity of age-specific versions of the AST.

Most theoretical formulations acknowledge that knowledge and awareness of cancer screening and prevention recommendations significantly influence health behaviors. This study compares perceived knowledge of cancer prevention and screening with test-based knowledge in a community sample. We also examine demographic variables and self-reported cancer screening and prevention behaviors as correlates of both knowledge scores, and consider whether cancer related knowledge can be accurately assessed using just a few, simple questions in a short and easy-to-complete survey. We used a community-partnered participatory research approach to develop our study aims and a survey. The study sample was composed of 180 predominantly African American and Hispanic community individuals who participated in a full-day cancer prevention and screening promotion conference in South Los Angeles, California, on July 2011. Participants completed a self-administered survey in English or Spanish at the beginning of the conference. Our data indicate that perceived and test-based knowledge scores are only moderately correlated. Perceived knowledge score shows a stronger association with demographic characteristics and other cancer related variables than the test-based score. Thirteen out of twenty variables that are examined in our study showed a statistically significant correlation with the perceived knowledge score, however, only four variables demonstrated a statistically significant correlation with the test-based knowledge score. Perceived knowledge of cancer prevention and screening was assessed with fewer items than test-based knowledge. Thus, using this assessment could potentially reduce respondent burden. However, our data demonstrate that perceived and test-based knowledge are separate constructs.

The purpose of the present study was to evaluate the validity of the EQ-5D in patients with Parkinson's disease (PD) in Singapore. In a cross-sectional survey, patients with PD completed English or Chinese version of the EQ-5D, the 8-item Parkinson's disease questionnaire (PDQ-8), and questions assessing socio-demographic and health characteristics. Clinical data were retrieved from patients' medical records. The validity of the EQ-5D was assessed by testing a-priori hypotheses relating the EQ-5D to the PDQ-8 and clinical data. Two hundred and eight PD patients (English speaking: 135) participated in the study. Spearman correlation coefficients between the EQ-5D and PDQ-8 ranged from 0.25 to 0.75 for English-speaking patients and from 0.16 to 0.67 for Chinese-speaking patients. By and large, the EQ-5D scores were weakly or moderately correlated with Hoehn and Yahr stage (correlation coefficients: 0.05 to 0.43), Schwab and England Activities of Daily Living score (correlation coefficients: 0.10 to 0.60), and duration of PD (correlation coefficients: 0.16 to 0.43). The EQ-5D index scores for patients with dyskinesia or "wearing off" periods were significantly lower than those without these problems. The EQ-5D Visual Analog Scale (EQ-VAS) scores also differed for English-speaking patients with deferring dyskinesia, "wearing off" periods, or health transition status; however, such differences were not observed in patients who completed the survey in Chinese. The EQ-5D questionnaire appears valid for measuring quality of life in patients with PD in Singapore. However, the validity of EQ-VAS in Chinese-speaking patients with PD should be further assessed.

Complete denture therapy is one such modality where science and art goes hand in hand. Selection of artificial teeth for completely edentulous patients is not easy in the absence of pre extraction records, because till date concrete guidelines do not exist. The purpose of this study was to determine if a correlation existed between the visible length of the iris and the length of the maxillary central incisor to potentially provide a guide for teeth selection. A total of 20 Indian dental students consented to participate in the pilot study. Standardized digital images of the face revealing the eyes and component of teeth on smiling was captured using a digital camera. The digital measurements of the visible iris length (medial aperture height, tangential to iris) and the length of the maxillary central incisor from the zenith to the incisal edge were analysed using Adobe Photoshop creative cloud software. The data was statistically evaluated and results were tabulated. Karl Pearson's Coefficient of Correlation was utilized to detect if any association existed between the two variables. The mean value of length of central incisor was 10.39 mm and the mean value of the visible length of iris was found to be 12.9 mm. A Pearson correlation analysis revealed an r-value <0.3 indicating minimal association between the two variables with a p-value >0.01 (.322). On inference, the correlation between the visible iris length and that of maxillary central incisor were unable to produce a strong positive statistical association. However, an association factor between the two has been obtained. Deduction of 2.5 mm from the dimension of visible iris length will help in attaining the length of artificial maxillary central incisor tooth.

Functional brain imaging studies have improved our knowledge of the neural localization of language functions and the functional reorganization after a lesion. However, the neural correlates of agrammatic symptoms in aphasia remain largely unknown. The present fMRI study examined the neural correlates of morpho-syntactic encoding and agrammatic errors in continuous language production by combining three approaches. First, the neural mechanisms underlying natural morpho-syntactic processing in a picture description task were analyzed in 15 healthy speakers. Second, agrammatic-like speech behavior was induced in the same group of healthy speakers to study the underlying functional processes by limiting the utterance length. In a third approach, five agrammatic participants performed the picture description task to gain insights in the neural correlates of agrammatism and the functional reorganization of language processing after stroke. In all approaches, utterances were analyzed for syntactic completeness, complexity, and morphology. Event-related data analysis was conducted by defining every clause-like unit (CLU) as an event with its onset-time and duration. Agrammatic and correct CLUs were contrasted. Due to the small sample size as well as heterogeneous lesion sizes and sites with lesion foci in the insula lobe, inferior frontal, superior temporal and inferior parietal areas the activation patterns in the agrammatic speakers were analyzed on a single subject level. In the group of healthy speakers, posterior temporal and inferior parietal areas were associated with greater morpho-syntactic demands in complete and complex CLUs. The intentional manipulation of morpho-syntactic structures and the omission of function words were associated with additional inferior frontal activation. Overall, the results revealed that the investigation of the neural correlates of agrammatic language production can be reasonably conducted with an overt language production paradigm. PMID:24711802

This study evaluated the construct of childhood traumatic grief (CTG) and its correlates through a multi-site assessment of 132 bereaved children and adolescents. Youth completed a new measure of the characteristics, attributions, and reactions to exposure to death (CARED), as well as measures of CTG, posttraumatic stress disorder (PTSD), depression, and anger. CTG was distinct from but highly correlated with PTSD, depression, and, to a lesser degree, anger. In contrast to a recent study of complicated grief, CTG severity was significantly associated with the degree to which the death was viewed as traumatic. CTG was also associated with caregivers' emotional reaction at the time of the death and caregivers' current sadness. Clinical implications and recommendations for future research are discussed.

A Correlated Ab Initio Study of Linear Carbon-Chain Radicals C(sub n)H (n=2-7)

Woon, David E.

1995-01-01

Linear carbon-chain radicals C(sub n) H for n = 2-7 have been studied with correlation consistent valence and core-valence basis sets and the coupled cluster method RCCSD(T). Equilibrium structures, rotational constants, and dipole moments are reported and compared with available experimental data. The ground state of the even-n series changes from 2Sigma(+) to 2Pi as the chain is extended. For C4H, the 2Sigma(+) state was found to lie only 72 cm(exp -1) below the 2Pi state in the estimated complete basis set limit for valence correlation. The C2H(-) and C3H(-) anions have also been characterized.

Cocaine treatment trials suffer from a high rate of attrition. We examined pretreatment neurophysiological factors to identify participants at greatest risk. Twenty-five participants were divided into concordant and discordant groups following electroencephalogram (EEG) measures recorded prior to a double-blind, placebo-controlled treatment trial. Three possible outcomes were examined: successful completion, dropout, and removal. Concordant (high perfusion correlate) participants had an 85% rate of successful completion, while discordant participants had a 15% rate of successful completion. Twenty-five percent of dropouts and 50% of participants removed were discordant (low perfusion correlate), while only 25% of those who completed were discordant. Failure to complete the trial was not explained by depression, craving, benzoylecgonine levels or quantitative electroencephalogram (QEEG) power; thus cordance may help identify attrition risk.

[Purpose] The purpose of this study was to examine the correlation of age, work experience, cognition, and work ability in older employees working in heavy industry. [Subjects and Methods] The study was conducted using 100 subjects who were over 55 years old and worked in heavy industry. To obtain data, we first had the subjects complete the MoCA-K test and Work Ability Index (WAI). The data were then analyzed by frequency and correlation using statistical software (SPSS 21.0). [Results] Through this study, we discovered a significant positive correlation between WAI and MoCA-K, age, and work experience. [Conclusion] This study revealed that work ability in older employees increases not with the number of years worked but with the enhancement of cognitive ability. Special management that focuses on cognition is therefore required for senior employees working in the field of heavy industry.

Objectives To reevaluate and validate the use of a formula for calculating the amount of continuing education credit to be awarded for printed home study courses. Methods Ten home study courses were selected for inclusion in a study to validate the formula, which is based on the number of words, number of final examination questions, and estimated difficulty level of the course. The amount of estimated credit calculated using the a priori formula was compared to the average amount of time required to complete each article based on pharmacists' self-reporting. Results A strong positive relationship between the amount of time required to complete the home study courses based on the a priori calculation and the times reported by pharmacists completing the 10 courses was found (p < 0.001). The correlation accounted for 86.2% of the total variability in the average pharmacist reported completion times (p < 0.001). Conclusions The formula offers an efficient and accurate means of determining the amount of continuing education credit that should be assigned to printed home study courses. PMID:19503705

A previously derived condition for the complete destructive interference of partially coherent light emerging from a trio of pinholes in an opaque screen is generalized to the case when the coherence properties of the field are asymmetric. It is shown by example that the interference condition is necessary, but not sufficient, and that the existence of complete destructive interference also depends on the intensity of light emerging from the pinholes and the system geometry; more general conditions for such interference are derived. The phase of the wave field exhibits both phase singularities and correlation singularities, and a number of nonintuitive situations in which complete destructive interference occurs are described and explained.

Patients with bidirectional cavopulmonary anastomosis have unphysiologically high superior caval vein pressure as it equals pulmonary artery pressure. Elevated superior caval vein pressure may cause communicating hydrocephalus and macrocephaly. This study analysed whether there exists an association between head circumference and superior caval vein pressure in patients with single ventricle physiology. We carried out a retrospective analysis of infants undergoing Fontan completion at our institution from 2007 to 2013. Superior caval vein pressures were measured during routine catheterisation before bidirectional cavopulmonary anastomosis and Fontan completion as well as head circumference, adjusted to longitudinal age-dependent percentiles. We included 74 infants in our study. Median ages at bidirectional cavopulmonary anastomosis and Fontan were 4.8 (1.6-12) and 27.9 (7-40.6) months, respectively. Head circumference showed significant growth from bidirectional cavopulmonary anastomosis until Fontan completion (7th (0-100th) versus 20th (0-100th) percentile). There was no correlation between superior caval vein pressure and head circumference before Fontan (R2=0.001). Children with lower differences in superior caval vein pressures between pre-bidirectional cavopulmonary anastomosis and pre-Fontan catheterisations showed increased growth of head circumference (R2=0.19). Patients with moderately elevated superior caval vein pressure associated with single ventricle physiology did not have a tendency to develop macrocephaly. There is no correlation between superior caval vein pressure before Fontan and head circumference, but between bidirectional cavopulmonary anastomosis and Fontan head circumference increases significantly. This may be explained by catch-up growth of head circumference in patients with more favourable haemodynamics and concomitant venous pressures in the lower range. Further studies with focus on high superior caval vein pressures are needed to exclude or prove a correlation.

Optimizing the mobility of residents with dementia: a pilot study promoting healthcare aide uptake of a simple mobility innovation in diverse nursing home settings.

Slaughter, Susan E; Estabrooks, Carole A

2013-10-18

Almost 90 percent of nursing home residents have some type of mobility limitation. Many spend most of their waking hours lying in bed or sitting. Such inactivity can negatively affect residents' health and general well-being. This pilot study aimed to assess (1) the effect of the sit-to-stand activity on mobility outcomes of nursing home residents, (2) the effect of an audit-and-feedback intervention on uptake of the sit-to-stand activity by healthcare aides, and (3) the contextual factors influencing uptake of the sit-to-stand activity by healthcare aides. This quasi-experimental pilot study was conducted in two nursing homes in western Canada. Twenty-six residents with dementia completed the sit-to-stand activity with 56 healthcare aides during daily care; separately, 71 healthcare aides completed a research use and context survey. Preliminary mobility feedback was presented to healthcare aides in one site. Resident mobility was measured using the 30-second sit-to-stand test. Healthcare aide uptake of the activity was measured using documentation flowsheets and a survey-based measure. Context was measured using the Alberta Context Tool. Mobility and uptake outcomes were analyzed over time and by site with analysis of covariance. Spearman and Pearson correlations were used to correlate context data with research use. Residents who more frequently completed the sit-to-stand activity were more likely to maintain or improve mobility compared with those who completed it less frequently (F=4.46; p=0.046, after adjustment for age). Uptake for one site was significantly different from the other (t-score=2.67; p=0.01, after adjustment for resident covariates). The audit-and-feedback intervention was associated with increased uptake of the activity from pre-intervention to post-intervention (t-score=-2.48; p=0.02). More context domains correlated significantly with aides' use of conceptual research and information sources in one site than the other. The sit-to-stand activity is a promising means to maintain or improve transfer ability of nursing home residents with dementia. In the nursing home with initially weak uptake, strengthened uptake followed an audit-and-feedback intervention. Activity participation was higher in the site with stronger correlations between context and measured research use. Results are sufficiently promising to warrant proceeding with a full clinical trial.

Changes in reward-related behavior are an important component of normal adolescent affective development. Understanding the neural underpinnings of these normative changes creates a foundation for investigating adolescence as a period of vulnerability to affective disorders, substance use disorders, and health problems. Studies of reward-related brain function have revealed conflicting findings regarding developmental change in the reactivity of the striatum and medial prefrontal cortex (mPFC) and have not considered puberty. The current study focused on puberty-specific changes in brain function and their association with mood. A sample of 77 healthy adolescents (26 pre-/early pubertal, 51 mid-/late pubertal) recruited in a narrow age range (mean = 11.94 years, SD = 0.75) were assessed for sexual maturation and circulating testosterone, completed a functional magnetic resonance imaging (fMRI) guessing task with monetary reward, and underwent experience sampling of mood in natural environments. For comparison, 19 healthy adults completed the fMRI assessment. Adolescents with more advanced pubertal maturation exhibited less striatal and more mPFC reactivity during reward outcome than similarly aged adolescents with less advanced maturation. Testosterone was positively correlated with striatal reactivity in boys during reward anticipation and negatively correlated with striatal reactivity in girls and boys during reward outcome. Striatal reactivity was positively correlated with real-world subjective positive affect and negatively correlated with depressive symptoms. mPFC reactivity was positively correlated with depressive symptoms. Reward-related brain function changes with puberty and is associated with adolescents' positive affect and depressive symptoms. Increased reward-seeking behavior at this developmental point could serve to compensate for these changes.

Assessment of impairment and disability measures on dynamic balance status of elderly patients is well documented in the rehabilitation of neuromuscular disorders. Few studies however considered similar evaluation in musculoskeletal disorders. To determine the influence of pain, hip range of motion and level of activity on dynamic balance among elderly people with hip osteoarthritis (OA). Elderly patients with hip OA participated in the cross-sectional survey. The impairment measures were assessed using the visual analogue scale and double-arm universal goniometer whilst their levels of activity were assessed with the Barthel Index. Participants performed Turn-180 on two trials by taking steps clockwise and anti-clockwise round a sturdy arm chair. The total number of steps taken to complete each Turn- 180 was determined. Descriptive statistics were used to summarize data whilst Pearson moment correlation coefficient determined the correlations of the variables at 95% confidence interval. The study involved 87 participants comprising 40(46%) males and 47(54%) females. The age of the participants ranged from 60 to 74 years with a mean of 65.8±4.5 years. There was a positive and significant correlation (r=0.596; p<0.001) between the participants' pain and steps taken to complete Turn-180. The participants' hip flexibility and the level of activity were also significantly and inversely correlated with the performance of Turn-180. The dynamic balance of the sampled elderly patients was considerably influenced by pain, hip flexibility and level of activity, thereby putting premium on the assessment of the variables during musculoskeletal rehabilitation of elderly patients.

The Oxford Knee Score (OKS) is a valid, short, self-administered, and site- specific outcome measure specifically developed for patients with knee arthroplasty. This study aimed to cross-culturally adapt and validate the OKS to be used in Turkish-speaking patients with osteoarthritis of the knee. The OKS was translated and culturally adapted according to the guidelines in the literature. Ninety-one patients (mean age: 55.89±7.85 years) with knee osteoarthritis participated in the study. Patients completed the Turkish version of the Oxford Knee Score (OKS-TR), Short-Form 36 Health Survey (SF-36), and Western Ontario and McMaster Universities Index (WOMAC) questionnaires. Internal consistency was tested using Cronbach's α coefficient. Patients completed the OKS-TR questionnaire twice in 7 days to determine the reproducibility. Correlation between the total results of both tests was determined by Spearman's correlation coefficient and intraclass correlation coefficients (ICC). Validity was assessed by calculating Spearman's correlation coefficient between the OKS, WOMAC, and SF-36 scores. Floor and ceiling effects were analyzed. Internal consistency was high (Cronbach's α: 0.90). The reproducibility tested by 2 different methods showed no significant difference (p>0.05). The construct validity analyses showed a significant correlation between the OKS and the other scores (p<0.05). There was no floor or ceiling effect in total OKS score. The OKS-TR is a reliable and valid measure for the self-assessment of pain and function in Turkish-speaking patients with osteoarthritis of the knee.

Empathy involves feeling compassion for others and imagining how they feel. In this article, we develop and validate the Single Item Trait Empathy Scale (SITES), which contains only one item that takes seconds to complete. In seven studies (N=5,724), the SITES was found to be both reliable and valid. It correlated in expected ways with a wide variety of intrapersonal outcomes. For example, it is negatively correlated with narcissism, depression, anxiety, and alexithymia. In contrast, it is positively correlated with other measures of empathy, self-esteem, subjective well-being, and agreeableness. The SITES also correlates with a wide variety of interpersonal outcomes, especially compassion for others and helping others. The SITES is recommended in situations when time or question quantity is constrained.

The article proposes a method of preliminary correlation processing of a complete set of antenna array signals used in the image reconstruction algorithm. The results of experimental studies of 3D reconstruction of various reflectors using and without correlation processing are presented in the article. Software ‘IDealSystem3D’ by IDeal-Technologies was used for experiments. Copper wires of different diameters located in a water bath were used as a reflector. The use of correlation processing makes it possible to obtain more accurate reconstruction of the image of the reflectors and to increase the signal-to-noise ratio. The experimental results were processed using an original program. This program allows varying the parameters of the antenna array and sampling frequency.

Predicting Alcohol, Cigarette, and Marijuana Use From Preferential Music Consumption.

This study investigated whether use of alcohol, cigarettes, and marijuana may be predicted from preferential consumption of particular music genres. Undergraduates (257 women and 78 men) completed a questionnaire assessing these variables. Partial correlation analyses, controlling for sensation-seeking tendencies and behaviors, revealed that listening to conventional music (pop, country, and religious genres) was negatively correlated with cigarette smoking (p=.001) and marijuana use (p<.001). Additionally, listening to energetic music (rap or hip-hop and soul or funk genres) was positively correlated with marijuana use (p=.004). The only significant predictor of alcohol use was country music, with which it was positively correlated (p=.04). This research suggests an especially harmful influence of energetic music on marijuana use. © The Author(s) 2015.

The objective of the present study was to examine the moderating role of interpersonal harmony in the relation of proactive personality with organizational citizenship behavior. 158 employees in Chinese state-owned companies completed the Proactive Personality Scale (Bateman & Crant, 1993), Harmony scale, and Organizational Citizenship Behavior Questionnaire. Proactive personality had insignificant correlation with job dedication. The correlation between interpersonal facilitation and proactive personality was significant but quite low. Results of the hierarchical regression analyses indicated that when demographic variables were controlled, Harmony had significant moderating effects on the relations of proactive behavior and job dedication/interpersonal facilitation. In the high Harmony group, the correlation between proactive personality and organizational citizenship behavior was significant; whereas in the low Harmony group, this correlation was not significant.

The literature on posttraumatic growth (PTG) is burgeoning, with the inconsistencies in the literature of the relationship between PTG and posttraumatic stress disorder (PTSD) symptoms becoming a focal point of attention. Thus, this meta-analysis aims to explore the relationship between PTG and PTSD symptoms through the Pearson correlation coefficient. A systematic search of the literature from January 1996 to November 2015 was completed. We retrieved reports on 63 studies that involved 26,951 patients. The weighted correlation coefficient revealed an effect size of 0.22 with a 95% confidence interval of 0.18 to 0.25. Meta-analysis provides evidence that PTG may be positively correlated with PTSD symptoms and that this correlation may be modified by age, trauma type, and time since trauma. Accordingly, people with high levels of PTG should not be ignored, but rather, they should continue to receive help to alleviate their PTSD symptoms.

To determine the correlation between rhinosinusitis symptoms as assessed by the Sino-Nasal Outcomes Test-20 (SNOT-20) and mucociliary clearance as assessed by the saccharin method. This was a cross-sectional study of 50 adult volunteers. Subjects completed the SNOT-20, and mucociliary clearance was determined with the saccharine method. Correlation coefficients (Spearman's Rho) were calculated for the global SNOT-20 score. The SNOT-20 scores varied from 20 to 54 (mean 30.28) with a possible range of 20 to 100. Clearance times varied from 418 to 2865 seconds (mean 999). There was no significant correlation between global SNOT-20 score and clearance time (r = 0.196). There is no significant correlation between rhinosinusitis symptoms as assessed by SNOT-20 scores and mucociliary clearance. Mucociliary clearance is important for the health of the sinonasal cavities, but clearance time does not appear to be associated with symptom severity in the population studied. A-1b.

The present study explored whether there were relationships among gender nonconformity, intelligence, and sexual orientation. A total of 106 heterosexual men, 115 heterosexual women, and 103 gay men completed measures of demographic variables, recalled childhood gender nonconformity (CGN), and the National Adult Reading Test (NART). NART error scores were used to estimate Wechsler Adult Intelligence Scale (WAIS) Full-Scale IQ (FSIQ) and Verbal IQ (VIQ) scores. Gay men had significantly fewer NART errors than heterosexual men and women (controlling for years of education). In heterosexual men, correlational analysis revealed significant associations between CGN, NART, and FSIQ scores (elevated boyhood femininity correlated with higher IQ scores). In heterosexual women, the direction of the correlations between CGN and all IQ scores was reversed (elevated girlhood femininity correlating with lower IQ scores). There were no significant correlations among these variables in gay men. These data may indicate a "sexuality-specific" effect on general cognitive ability but with limitations. They also support growing evidence that quantitative measures of sex-atypicality are useful in the study of trait sexual orientation.

Although pelvic floor muscle training (PFMT) is effective for stress urinary incontinence (SUI), patients need to be motivated to obtain cure. An instrument to assess motivation in such patients was published in 2009: the Incontinence Treatment Motivation Questionnaire (ITMQ). The ITMQ consists of five domains: (i) positive attitudes toward PFMT; (ii) reasons for not doing PFMT; (iii) difficulties living with incontinence; (iv) desire for treatment; and (v) incontinence severity influencing motivation. The aim of the present study was to examine the relationship between ITMQ scores and treatment success. After referral for PFMT, women with SUI completed the ITMQ. Pre- and post-treatment outcomes were the International Consultation on Incontinence Questionnaire (ICIQ) score and a 24-hr pad test. Correlations between ITMQ scores and baseline, as well as post-treatment change in ICIQ scores and pad test results were examined. Additionally, the demographics of non-participants, participants, and patients lost to follow-up were compared. Of 85 recruits, 18 did not complete the ITMQ, 14 were lost to follow-up, thus 53 completed the PFMT programme and undertook either one or both outcomes. Pre-treatment, severity on ICIQ correlated with total ITMQ (ρ = 0.33, P = 0.01). Post-treatment change in pad test was inversely correlated with Domain 2 (ρ = -0.33, P = 0.03). The pre-treatment severity of incontinence was significantly associated with motivation for treatment. Unfortunately, post-treatment change correlated with only one domain of the questionnaire. Further modification of the ITMQ is envisaged. Neurourol. Urodynam. 36:316-321, 2017. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

This correlational study explored the Resilience Scale for Adolescents (READ) as a predictor for developing depressive symptoms controlling for known risk factors. A young adolescent sample (N = 387) completed the READ, the Short Mood and Feeling Questionnaire (SMFQ), Social Phobia Anxiety Index for Children (SPAI-C), and the occurrence of Stressful Life Events (SLE). In addition, a subsample of their parents (N = 240) completed a parental version of READ (READ-P). The results indicated that the READ assesses important protective factors that are associated with fewer depressive symptoms among young adolescents even when controlling for known risk factors. All five READ-factors were predictors of depressive symptoms, while the READ-P showed no predictive value. There were no significant interaction effects between READ and SLE. There were, however, significant main-effects supporting a compensatory model of protective factors. The findings suggest that the READ is a significant predictor of mental health and a useful tool for further research examining differences in stress tolerance among young adolescents.

Background Efficient, accurate instruments for measuring depression are increasingly important in clinical practice. We developed a computerized adaptive version of the Beck Depression Inventory (BDI). We examined its efficiency and its usefulness in identifying Major Depressive Episodes (MDE) and in measuring depression severity. Methods Subjects were 744 participants in research studies in which each subject completed both the BDI and the SCID. In addition, 285 patients completed the Hamilton Depression Rating Scale. Results The adaptive BDI had an AUC as an indicator of a SCID diagnosis of MDE of 88%, equivalent to the full BDI. The adaptive BDI asked fewer questions than the full BDI (5.6 versus 21 items). The adaptive latent depression score correlated r = .92 with the BDI total score and the latent depression score correlated more highly with the Hamilton (r = .74) than the BDI total score did (r = .70). Conclusions Adaptive testing for depression may provide greatly increased efficiency without loss of accuracy in identifying MDE or in measuring depression severity. PMID:15132755

Objective Although extant studies indicate that there is a strong association between Attention Deficit/Hyperactivity Disorder (ADHD) and reading ability in elementary school children, knowledge regarding the relation between inattentive and hyperactive/impulsive behaviors and emergent literacy in preschool children is less established. This study examined the unique and overlapping relations between measures that assess inattention and hyperactivity/impulsivity and emergent literacy skills in preschool children. Method Participants included 204 preschool children (Mean age = 56 months; 50.9% female; 79.8% European American). Behavioral rating scales were completed by teachers and the Continuous Performance Test (CPT) and the Test of Preschool Early Literacy were completed by the preschoolers. Results Across measures, inattention was a unique correlate of emergent literacy skills whereas hyperactivity/impulsivity was not. Both rating scales and the CPT indices of inattention were uniquely associated with emergent literacy skills. Conclusions These results suggest that these measures are assessing different manifestations of inattention that are both unique correlates of early reading skills. PMID:23186142

Spatiotemporal image correlation spectroscopy (STICS) theory, verification, and application to protein velocity mapping in living CHO cells.

We introduce a new extension of image correlation spectroscopy (ICS) and image cross-correlation spectroscopy (ICCS) that relies on complete analysis of both the temporal and spatial correlation lags for intensity fluctuations from a laser-scanning microscopy image series. This new approach allows measurement of both diffusion coefficients and velocity vectors (magnitude and direction) for fluorescently labeled membrane proteins in living cells through monitoring of the time evolution of the full space-time correlation function. By using filtering in Fourier space to remove frequencies associated with immobile components, we are able to measure the protein transport even in the presence of a large fraction (>90%) of immobile species. We present the background theory, computer simulations, and analysis of measurements on fluorescent microspheres to demonstrate proof of principle, capabilities, and limitations of the method. We demonstrate mapping of flow vectors for mixed samples containing fluorescent microspheres with different emission wavelengths using space time image cross-correlation. We also present results from two-photon laser-scanning microscopy studies of alpha-actinin/enhanced green fluorescent protein fusion constructs at the basal membrane of living CHO cells. Using space-time image correlation spectroscopy (STICS), we are able to measure protein fluxes with magnitudes of mum/min from retracting lamellar regions and protrusions for adherent cells. We also demonstrate the measurement of correlated directed flows (magnitudes of mum/min) and diffusion of interacting alpha5 integrin/enhanced cyan fluorescent protein and alpha-actinin/enhanced yellow fluorescent protein within living CHO cells. The STICS method permits us to generate complete transport maps of proteins within subregions of the basal membrane even if the protein concentration is too high to perform single particle tracking measurements.

School non-completion and early work disability is a great public health challenge in Norway, as in most western countries. This study aims to investigate how medically based disability pension (DP) among young adults varies geographically and how municipal socioeconomic conditions interact with non-completion of secondary education in determining DP risk. The study includes a nationally representative sample of 30% of all Norwegians (N = 350,699) aged 21-40 in 2010 from Statistic Norway's population registries. Multilevel models incorporating factors at the individual, neighbourhood and municipal levels were applied to estimate the neighbourhood and municipality general contextual effects in DP receipt, and detect possible differences in the impact of municipal socioeconomic conditions on DP risk between completers and non-completers of secondary education. A pattern of spatial clustering at the neighbourhood (ICC = 0.124) and municipality (ICC = 0.021) levels are clearly evident, indicating that the underlying causes of DP receipt have a systematic neighbourhood and municipality variation in Norway. Non-completion of secondary education is strongly correlated with DP receipt among those younger than 40. Socioeconomic characteristics of the municipality are also significantly correlated with DP risk, but these associations are conditioned by the completion of secondary education. Living in a socioeconomically advantageous municipality (i.e. high income, high education levels and low unemployment and social security payment rates) is associated with a higher risk of DP, but only among those who do not complete their secondary education. Although the proportion of DPs was equal in rural and urban areas, it is evident that young people living in urban settings are more at risk of early DP than their counterparts living in rural parts of the country when controlling for other risk factors. The association between school non-completion and DP risk varies between municipalities and local socioeconomic environments. The interplay between personal characteristics and the local community is important in DP risk among young adults, implying that preventive measures should be directed not only at the individual level, but also include the educational system and the local community.

The Active Australia Survey (AAS) is used for physical activity (PA) surveillance in the general Australian adult population, but its validity in older adults has not been evaluated. Our aim was to examine the convergent validity of the AAS questions in older adults. The AAS was validated against pedometer step counts as an objective measure of PA, self-reported physical function, and a step-test to assess cardiorespiratory fitness. Participants were community-dwelling adults, aged 65-89 y, with the ability to walk 100 m. They completed a self-administered AAS and the step-test in one interview. One week earlier, they completed the Short Form-36 physical function subscale. Between these two interviews, they each wore a YAMAX Digiwalker SW200 pedometer and recorded daily steps. Using the AAS data, daily walking minutes and total PA minutes (walking, moderate-intensity PA and vigorous-intensity PA) were compared with the validity measures using Spearman rank-order correlations. Fifty-three adults completed the study. Median daily walking minutes were 34.2 (interquartile range [IQR] 17.1, 60.0), and median daily total PA minutes were 68.6 (IQR 31.4, 113.6). Walking and total PA minutes were both moderately correlated with pedometer steps (Spearman correlation r=0.42, p=0.003, for each) but not with step-test seconds to completion (r=-0.11, p=0.44; r=-0.25, p=0.08, respectively). Total PA minutes were significantly correlated with physical function scores (r=0.39, p=0.004), but walking minutes were not (r=0.15, p=0.29). This initial examination of the psychometric properties of the AAS for older adults suggests that this surveillance tool has acceptable convergent validity for ambulatory, community-dwelling older adults.

To provide information on the Five-Times-Sit-to-Stand (FTSTS) and Timed-Up-and-Go (TUG) tests in persons with injection-related venous ulcers (VU+) and persons without venous ulcers (VU-). This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to: To examine functional mobility using Five-Times-Sit-to-Stand (FTSTS) and Timed-Up-and-Go (TUG) tests in persons with injection-related venous ulcers (VU+) and compare these findings to persons without venous ulcers (VU-). Cross-sectional, comparative design. Outpatient clinic.PARTICPANTS: Participants (n = 61) were 31 persons VU+ and 30 persons VU-; 57.4% men; mean age, 54 years; 93% African American. Five-Times-Sit-to-Stand, TUG, physical activity, quality of life, comorbidities, falls, and body mass index. Participants VU+ were 36.8% slower on completion of the TUG test (P = .012) and 26.5% slower on completion of the FTSTS test (P = .081). Five-Times-Sit-to-Stand and TUG were strongly correlated with each other, r = 0.93, 0.87, P < .001 for VU- and VU+, respectively. Test-retest reliabilities for the FTSTS and TUG tests were high (intraclass correlation coefficient = 0.89-0.94) for the VU+ and VU-. Within each group, correlations of FTSTS and TUG were similar for each of the variables examined. Across groups, correlations showed that the time to complete FTSTS and TUG increased as a function of comorbidities in the VU+ group; the correlations in the VU- group were not significantly different from zero. The VU+ group exhibited poorer physical performance than the VU- group. The high correlation between FTSTS and TUG and the similarity of correlations with other variables suggest that these physical performance measures may be interchangeable in their ability to predict physical functioning in these clinical groups despite differences in test demands. Clinicians need easy-to-perform reliable clinical tests such as FTSTS and TUG to assess mobility of aging injection users with venous ulcers.

To investigate the views and assess motivation, attitudes of pharmacists in Lebanon towards mandatory continuous education (CE), its transition to Continuous Professional Development (CPD), and identify barriers to participation in CPD. A cross-sectional observational study, conducted between February and May 2017, enrolled 591 pharmacists. The questionnaire used in this study was developed after an extensive literature review and based on previous similar studies in different countries. Half of the pharmacists who completed the questionnaire agreed that all the factors that were mentioned in the questionnaire motivated completing CPD, whereas 55.4% felt confident that CPD meets their needs. 78.4% felt confident in their abilities to assess what they have learned. 71.6% felt confident in their abilities to assess what additional CPD activity may be necessary. The majority of the pharmacists agreed that accessibility of group learning activities (location/distance) (69.6%), job restrictions (76.3%) and lack of time (80.6%) were the most essential barriers against participation in CPD. Motivation was significantly and positively correlated with attitude (r= 0.718), but negatively correlated with barriers (r= -0.243). Attitude was significantly and negatively correlated with barriers (r= -0.120). Our findings contribute to informing the forward pathway for the profession. Attitude and motivation to CPD were positive in this study. Accessibility of group learning activities due to distance and location, job restrictions and lack of time were the major barriers to participation in CPD. Potential solutions can be sought to address these issues.

Behavioral science priorities in residency education: The perspective of practicing family physicians.

Brandt-Kreutz, Richard L; Ferguson, Kyle E; Sawyer, Devin

2015-12-01

The family medicine residency behavioral science curriculum is more effective if prioritized to match what is needed in practice after graduation. Two prior studies (Kendall, Marvel, & Cruickshank, 2003; Marvel & Major, 1999) identified physician priorities for behavioral science education. The present study extends this research to include topics from more recent curriculum guidelines and examines the extent to which size of community and perceived competence correlate with prioritization of Washington state family physicians. Practicing family physicians in Washington state (N = 2,270) were invited to complete the survey. Respondents provided demographic and practice information. Respondents then rated, on a scale from 1 to 4, 35 behavioral science topics on 2 different scales including (a) priority to be given in residency education and (b) perceived level of competence. A total of 486 responded and 430 completed both priority and competence scales for a response rate of 19%. The top half of 35 topics of the present study included the top 13 topics found in the 2 prior studies. Priority and competence scales were moderately correlated (r = .48, n = 430, p = .001). There was a small significant correlation with size of community and priority ratings (r = .13, n = 435, p = .006). Family physicians in Washington state prioritize behavioral science topics in residency education similar to Colorado and Mississippi. The results of this study support recent ACGME guidelines, in that training should focus on common psychiatric illnesses, including depression and anxiety, and interpersonal processes.

2007-01-01

Participants of stuttering treatment programs provide an opportunity to evaluate persons who stutter as they demonstrate varying levels of fluency. Identifying physiologic correlates of altered fluency levels may lead to insights about mechanisms of speech disfluency. This study examined respiratory, orofacial kinematic and acoustic measures in 35 persons who stutter prior to and as they were completing a 1-month intensive stuttering treatment program. Participants showed a marked reduction in stuttering severity as they completed the treatment program. Coincident with reduced stuttering severity, participants increased the amplitude and duration of speech breaths, reduced the rate of lung volume change during inspiration, reduced the amplitude and speed of lip movements early in the test utterance, increased lip and jaw movement durations, and reduced syllable rate. A multiple regression model that included two respiratory measures and one orofacial kinematic measure accounted for 62% of the variance in changes in stuttering severity. Finally, there was a weak but significant tendency for speech of participants with the largest reductions in stuttering severity to be rated as more unnatural as they completed the treatment program.

The aim of this study was to investigate whether the final displacement of conservatively treated distal radius fractures can be predicted after primary reduction. We analysed the radiographic documents of 311 patients with a conservatively treated distal radius fracture at the time of injury, after reduction and after bony consolidation. We measured the dorsal angulation (DA), the radial angle (RA) and the radial shortening (RS) at each time point. The parameters were analysed separately for metaphyseally “stable” (A2, C1) and “unstable” (A3, C2, C3) fractures, according to the AO classification system. Spearman’s rank correlations and regression functions were determined for the analysis. The highest correlations were found for the DA between the time points ‘reduction’ and ‘complete healing’ (r = 0.75) and for the RA between the time points ‘reduction’ and ‘complete healing’ (r = 0.80). The DA and the RA after complete healing can be predicted from the regression functions. PMID:18504577

2004-01-01

The purpose of this study was to examine postprogram exercise motivation and adherence in cancer survivors who participated in the Group Psychotherapy and Home-Based Physical Exercise (GROUP-HOPE; Courneya, Friedenreich, Sela, Quinney, & Rhodes, 2002) trial. At the completion of the GROUP-HOPE trial, 46 of 51 (90%) participants in the exercise group completed measures of attribution theory constructs. A 5-week follow-up self-report of exercise was then completed by 30 (65%) participants. Correlational analyses indicated that program exercise, perceived success, expected success, and affective reactions were strong predictors of postprogram exercise. In multivariate stepwise regression analyses, program exercise and perceived success were the strongest predictors of postprogram exercise. Additionally, perceived success was more important than objective success in understanding the attribution process, and it interacted with personal control to influence expected success and negative affect. Finally, postprogram quality of life and changes in physical fitness were correlates of perceived success. We concluded that attribution theory may have utility for understanding postprogram exercise motivation and adherence in cancer survivors.

This study examined factors associated with teens' adherence to a multiple health behavior cancer preventive intervention. Analyses identified predictors of trial enrollment, run-in completion, and adherence (intervention initiation, number of sessions completed). Of 104 teens screened, 73% (n = 76) were trial eligible. White teens were more likely to enroll than non-Whites (χ(2)[1] df = 4.49, p = .04). Among enrolled teens, 76% (n = 50) completed the run-in; there were no differences between run-in completers and noncompleters. A majority of run-in completers (70%, n = 35) initiated the intervention, though teens who initiated the intervention were significantly younger than those who did not (p < .05). The mean number of sessions completed was 5.7 (SD = 2.6; maximum = 8). After adjusting for age, teens with poorer session engagement (e.g., less cooperative) completed fewer sessions (B = -1.97, p = .003, R (2) = .24). Implications for adolescent cancer prevention research are discussed.

To emphasize the importance of regular exercising in dry lab in initial phase of learning of laparoscopic surgery by a practicing urologist. The study was performed at Dry Lab -Jayaramdas Patel Academic Centre (JPAC) attached to Muljibhai Patel Urological Hospital, Nadiad, India. The study is based on 30 sets of exercises of four standard tasks utilized to learn Hand-Eye coordination for Laparoscopic Surgery. All sets were performed by a single participant over a period of 19 days and the exercise record was retrospectively analyzed. The participant had limited exposure of one year in a low volume laparoscopy center. Correlation between Exercise number and Task Completion Time (TCT) was calculated by Pearson's Correlation Coefficient and its significance is assessed by Student paired t test. The current study describes 30 exercises of 4 standard tasks for hand-eye-coordination. Although the study was completed in 19 days but there were two intervals which point to the objective of this study. First interval was of 3 days and it occurred after 4th exercise. At 5th exercise the Task Completion Time started rising more than the 2nd exercise. This regression further worsened on 6th exercise which had an interval of 2 days. Here the (TCT) went up almost equal to 1st exercise (1050 vs 1054 seconds). Mean time for IT1, IT2, IT3, IT4 and TCT of over all exercises were calculated as 24.2 +/- 3.7, 121.9 +/- 54.9, 233 +/- 73.5, 199 +/- 55.1 and 582.5 +/- 174.8 seconds respectively. Significant correlation was noticed between number of exercises performed and improvement in time taken for individual tasks (IT 2 to IT4) and TCT. However there was no significant impact on Task 1. Regular Dry Lab exercises improves hand eye coordination and psychomotor skill dedicated continuous exercising has significant impact in reducing TCT.

Association of study quality with completeness of reporting: have completeness of reporting and quality of systematic reviews and meta-analyses in major radiology journals changed since publication of the PRISMA statement?

To evaluate whether completeness of reporting of systematic reviews and meta-analyses in major radiology journals has changed since publication of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement; a secondary objective is to evaluate whether completeness of reporting (ie, PRISMA) is associated with study quality (ie, Assessing the Methodological Quality of Systematic Reviews [AMSTAR]). Systematic reviews and meta-analyses published in major radiology journals between January 2007 and December 2011 were identified by searching MEDLINE with the modified Montori method. Studies were reviewed independently by two investigators and assessed for adherence to the AMSTAR and PRISMA checklists. The average results were analyzed to assess for change in mean score before and after PRISMA publication and to assess results over time; a Pearson correlation coefficient was calculated to assess for any association between PRISMA and AMSTAR results. Included were 130 studies from 11 journals. Average PRISMA and AMSTAR results were 21.8 of 27 and 7.2 of 11, respectively. The average result was higher after publication of PRISMA, and PRISMA-reported items were 22.6 of 27 after publication of PRISMA versus 20.9 of 27 before publication of PRISMA; AMSTAR results were 7.7 of 11 after publication of PRISMA versus 6.7 of 11 before publication of PRISMA. There was a strong positive correlation (r = 0.86) between the PRISMA and AMSTAR results. There was high variability between journals. Radiology had the highest PRISMA reported items (24.7 of 27), and American Journal of Neuroradiology had the lowest (19.6 of 27). Two major areas for improvement include study protocol registration and assessment of risk of bias across studies (ie, publication bias). In major radiology journal studies, there was modest improvement in completeness of reporting of systematic reviews and meta-analyses, assessed by PRISMA, which was strongly associated with higher study quality, assessed by AMSTAR. http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.13130273/-/DC1.

A Mixed-Method Study on Correlates of HIV-Related Stigma Among Gay and Bisexual Men in the Southern United States.

PubMed

Berg, Rigmor C; Carter, Dakota; Ross, Michael W

Societal prejudice against people living with HIV infection is a formidable public health challenge that can negatively impact health and well-being. We recruited a multiethnic sample of 129 gay and bisexual men living with HIV who completed a brief survey; a subset of participants completed semi-structured qualitative interviews to contextualize the data. In bivariate analyses, stigma was positively and significantly correlated with depression (r = .402, p < .001) and negatively correlated with social support (r = -.482, p < .001). Qualitative interview results captured the mental suffering caused by stigma and coping strategies the men had developed. Although some of the coping strategies reduced the likelihood of experiencing acts of stigmatization, they also exacerbated the psychological stress of living with a stigmatized disease and limited the potential for social support. Our results highlight the need to scale up stigma-reduction programs, particularly those that can bolster social support networks. Copyright © 2017 Association of Nurses in AIDS Care.

2016-09-01

Falls in older adults with cancer are more common than in noncancer controls, yet no fall-risk screening tool has been validated in this population. We undertook a cross-sectional pilot study of the Falls Risk Questionnaire (FRQ) in 21 adults aged ≥65 receiving systemic cancer therapy. Participants completed the FRQ, geriatric assessment measures, and a measure of fear-of-falling. The recruitment rate was 87.5 %, with 95.2 % completion of the FRQ and additional geriatric assessment and quality of life measures. The FRQ correlated significantly with the Timed Up and Go test (Pearson r 0.479, p = 0.028). In addition, the FRQ score correlated directly with fear-of-falling and inversely with QOL, particularly physical health and neurotoxicity subscales. In conclusion, the FRQ was feasible in older adults receiving cancer therapy and correlates with measures of physical performance, functional status, and fear-of-falling. The FRQ may prove to be a valuable fall-risk screening tool to implement fall-prevention interventions in this vulnerable population of older adults with cancer.

[Purpose] The purpose of this study was to investigate the use of smartphones by university students in selected areas, their musculoskeletal symptoms, and the associated hazard ratio. [Subjects and Methods] This involved the completion of a self-administered questionnaire by dental hygiene students in Seoul, Gyeonggido, and Gyeongsangbukdo. The 292 completed copies of the questionnaire were then analyzed. [Results] The most painful body regions after the use of smartphones were found to be the shoulders and neck. In the musculoskeletal system, back pain was found to have a positive correlation with the size of the smartphone’s liquid crystal display (LCD) screen, and pain in legs and feet were found to have a negative correlation with the length of time that the smartphone was used. As a result, it was revealed that the use of a smartphone was correlated with musculoskeletal symptoms. [Conclusion] Therefore, in today’s environment, where the use of smartphones is on the rise, it is necessary to improve the ways that they are used and to develop a preventive program to alleviate the symptoms of musculoskeletal damage.

Lam, Jacob; Wilkinson, James; Brassett, Cecilia; Brown, Jonathan

2018-05-01

Background and study aim  Magnetic imaging technology is of proven benefit to trainees in colonoscopy, but few studies have examined its benefits in experienced hands. There is evidence that colonoscopy is more difficult in women. We set out to investigate (i) associations between the looping configurations in the proximal and distal colon and (ii) differences in the looping prevalence between the sexes. We have examined their significance in terms of segmental intubation times and position changes required for the completion of colonoscopy. Patients and methods  We analyzed 103 consecutive synchronized luminal and magnetic image videos of diagnostic colonoscopies with normal anatomy undertaken by a single experienced operator. Results  Deep transverse loops and sigmoid N-loops were more common in females. A deep transverse loop was more likely to be present if a sigmoid alpha-loop or N-loop had formed previously. Patients with sigmoid N-loops were turned more frequently from left lateral to supine before the sigmoid-descending junction was reached, but there was no statistical correlation between completion time and looping pattern. Conclusions  This study has reexamined the prevalence of the common looping patterns encountered during colonoscopy and has identified differences between the sexes. This finding may offer an explanation as to why colonoscopy has been shown to be more difficult in females. Although a deep transverse loop following a resolved sigmoid alpha-loop was the most commonly encountered pattern, no statistical correlation between completion time and looping pattern could be shown. It is the first study to examine segmental completion times using a magnetic imager in expert hands.

We present a phase 2, single-arm study evaluating 800 mg daily venetoclax, a highly selective, oral small-molecule B-cell leukemia/lymphoma-2 (BCL-2) inhibitor in patients with high-risk relapsed/refractory acute myelogenous leukemia (AML) or unfit for intensive chemotherapy. Responses were evaluated following revised International Working Group (IWG) criteria. The overall response rate was 19%; an additional 19% of patients demonstrated anti-leukemic activity not meeting IWG criteria (partial bone marrow response and incomplete hematologic recovery). Twelve (38%) patients had isocitrate dehydrogenase 1/2 mutations, of whom 4 (33%) achieved complete response/complete response with incomplete blood count recovery. Six (19%) patients had BCL-2–sensitive protein index at screening, which correlated with time on study. BH3 profiling was consistent with on-target BCL-2 inhibition and identified potential resistance mechanisms. Common adverse events included nausea, diarrhea and vomiting (all grades), and febrile neutropenia and hypokalemia (grade 3/4). Venetoclax demonstrated activity and acceptable tolerability in patients with AML and adverse features. PMID:27520294

This research project examined the individual and combined effectiveness of an HIV prevention workshop and a free condom distribution program in four high schools in Tijuana, Mexico. Adolescents (N = 320) completed baseline measures on sexual practices and theoretical correlates and participated in a two-part study. In Study 1, students were randomly assigned to an HIV prevention workshop or a control condition, with a 3-month follow-up assessment. Results indicate three significant workshop benefits regarding HIV transmission by altering sexual initiation, access to condoms, and traditional beliefs regarding condoms. In Study 2, we set up a condom distribution program at two of the participating schools, and students completed a 6-month follow-up assessment. Results indicate that exposure to the workshop followed by access to the condom distribution program yielded two beneficial results for reducing HIV transmission: moderating sexual initiation and increasing condom acquisition. Access to the condom distribution program alone had no effects on behavioral and psychosocial correlates of HIV transmission. We discuss implications of these results.

Triceps tendon injuries are reported to be very rare. To our knowledge, there have been no studies describing its prevalence or injury patterns on MR imaging. The purpose of this retrospective study was to determine the prevalence and patterns of triceps injuries based on a large series of consecutive MR examinations. Clinical correlation was obtained. From 801 consecutive elbow MR examinations over a 15-year period, 28 patients with 30 triceps tendon injuries were identified and graded as partial tendon tear and complete tendon tear. The patients' medical records were reviewed to determine age, gender, cause of tears, and management. The prevalence of triceps tendon injuries was 3.8%. There were 5 women and 23 men with partial or complete tears (mean age: 46.6 years; range: 2.7 to 75.1 years). The most common injury was partial tear, found in 18 patients. There were 10 patients with 12 complete tears (2 had re-torn following surgical repair). A tear was suspected in 12 out 28 (43%) patients prior to the MRI. The most common presenting symptom was pain. The most common cause was athletic injury (8 patients [29%], including weightlifting [2 patients]). Tendon tear was found to be a complication of infection in 6 patients, and in 3 patients the tears were a complication of steroid use. Thirteen tendon tears were surgically repaired (8 of these were complete tears). Triceps tendon injury is not as rare as commonly reported and may often be clinically underdiagnosed.

To assess sexually related personal distress among premenopausal women with female sexual dysfunction (FSD) via a validated Arabic version of the Female Sexual Distress Scale (FSDS). A cross-sectional study was conducted among women attending Suez Canal University Hospital, Egypt, between May 2015 and July 2016. In a pilot study to evaluate test-retest reliability and internal consistency, 42 sexually active premenopausal women (aged ≥20 years) completed the Arabic FSDS at recruitment and 2 weeks later. Subsequently, premenopausal sexually active women (aged 20-45 years) were asked to complete the female sexual function index (FSFI) questionnaire; those with FSD (FSFI score ≤26.55) were invited to return to complete the validated version of the Arabic FSDS. The Arabic FSDS showed good test-retest reliability (Pearson correlation coefficient 0.93-0.98) and internal consistency (Cronbach α 0.83-0.92). Overall, 140 (58.1%) of 241 women who completed the FSFI had sexual dysfunction, of whom 51 (36.4%) had sexually related personal distress. Marriage duration was significantly increased among women with FSD (P<0.001). All FSFI sexual domains except lubrication were negatively correlated with FSDS. FSD and sexually related personal distress were highly interrelated and prevalent. An Arabic version of the FSDS was found to be valid and reliable for evaluation of sexually related personal distress. © 2017 International Federation of Gynecology and Obstetrics.

The purpose of this study was to investigate and assess the effects of musical therapy, painting inanimate-animate object pictures, and orientation to time-place-person interventions on the cognitive state, depression, and anxiety levels of mildly-affected Alzheimer's patients. The study using a quasi-experimental design was conducted with 27 mildly-affected Alzheimer's patients. The effects of the multisensory stimulation were evaluated with the "Mini Mental State Examination," the "Geriatric Depression Scale," and the "Beck Anxiety Scale." All of these were administered one day prior to beginning the study, immediately after its completion, and three weeks thereafter. A significant negative correlation was determined to exist between the MMSE-depression scores and MMSE-anxiety scores; the correlation between the depression-anxiety scores, on the other hand, had a positive significance. The shifts over time in the MMSE, depression and anxiety scores were significant. The primary conclusion of the study is that the multisensory stimulation method applied to mildly-affected Alzheimer's patients had a positive effect on their cognitive state, depression, and anxiety, and that this effect continued for three weeks following completion of the study intervention, with a tendency to decline progressively.

This study used mixed methods to examine the experiences and health of rural, young adult women (N = 100) who self-reported past experience of physical, emotional and verbal, sexual, and relational abuse in adolescent dating relationships. Few studies have examined the lasting health ramifications of adolescent dating abuse adolescent dating abuse in rural populations, and almost no mixed methods studies have explored adolescent dating abuse. Participants completed questionnaires on demographics, relationship behaviors, and mental health symptoms. A subsample (n = 10) of participants also completed semi-structured, in-depth interviews with the primary investigator. Results suggest that depressive symptoms and self-rating of health in these women are associated with particular kinds and severity of abusive experiences, and that adolescent dating abuse has ramifications for health and development beyond the duration of the original relationship. Self-rated health (SRH) was inversely associated with abusive behaviors in the relationship, whereas depressive symptoms were positively correlated with such behaviors. Self-rated health was also negatively correlated with depressive symptoms. The results of this study represent an important step toward establishing lifetime health risks posed by adolescent dating abuse. © The Author(s) 2014.

The relationships among perceived peer acceptance of sexual aggression, punishment certainty, and sexually aggressive behavior.

Researching the correlates of men's sexually aggressive behavior (i.e., verbal coercion and rape) is critical to both understanding and preventing sexual aggression. This study examined 120 men who completed an anonymous online questionnaire. The study aimed to determine the relative importance of two potential correlates of men's self-reported use of sexual aggression: (a) perceptions that male peers use and support sexual aggression and (b) perceptions of punishment likelihood associated with sexual aggression. Results revealed that perceptions of male friends' acceptance of sexual aggression were strongly associated with individual men's reports of using verbal coercion and rape. Perceptions of punishment likelihood were negatively correlated with verbal coercion but not with rape through intoxication and force. Implications for sexual aggression prevention are discussed.

Limited information exists regarding the association between flexibility and running economy in female athletes. This study examined relationships between lower limb and trunk flexibility and running economy in 17 female collegiate track athletes (20.12+/-1.80 y). Correlational design, subjects completed 4 testing sessions over a 2-week period. The 1st session assessed maximal oxygen uptake (VO2max=55.39+/-6.96 ml.kg-1.min-1). The 2nd session assessed trunk and lower limb flexibility. Two sets of 6 trunk and lower limb flexibility measures were performed after a 10-min treadmill warm-up at 2.68 m.s-1. The 3rd session consisted of 3 10-min accommodation runs at a speed of 2.68 m.s-1 which was approximately 60% VO2max. Each accommodation bout was separated by a 10-min rest. The 4th session assessed running economy. Subjects completed a 5-min warm-up at 2.68 m.s-1 followed by 10-min economy run at 2.68 m.s-1. Pearson product moment correlations revealed no significant correlations between running economy and flexibility measures. Results are in contrast to studies demonstrating an inverse relationship between trunk and/or lower limb flexibility and running economy in males. Furthermore, results are in contrast to studies reporting positive relationships between flexibility and running economy.

To develop and validate a sports activity scale for patients with a diagnosis of femoroacetabular impingement (FAI).
 A nine level Hip Sports Activity Scale (HSAS) was constructed both in German and English languages. Fifty-nine consecutive patients undergoing surgical treatment for FAI at two centers in Switzerland and in the US completed a questionnaire set consisting of the HSAS, the University of California at Los Angeles (UCLA) activity scale and different hip joint-specific and generic outcome tools. For reliability assessment, the HSAS was completed twice about nine days apart. Evidence of reliability, validity and responsiveness was investigated by classical psychometric analyses.
 Reliability was excellent for both the German and the English versions with intraclass correlation coefficients of 0.94 and 0.96, respectively. Evidence of convergent validity was supported by moderate to high correlations with the UCLA activity scale and with the joint-specific measures used. Evidence of divergent validity was supported by low correlations with the SF-12 Mental Component Scale and the WOMAC stiffness subscale. The standardised response mean was 0.69.
 The HSAS is a reliable and valid tool to determine sports levels in patients suffering from FAI. Its use in future studies investigating outcomes in young patients with hip disease can be recommended.

Web-based questionnaires are becoming increasingly valuable for clinical research. The Female Sexual Function Index (FSFI) is the gold standard for evaluating female sexual function; yet, it has not been validated in this format. We sought to validate the Female Sexual Function Index (FSFI) for web-based administration. Subjects enrolled in a web-based research survey of sexual function from the general population were invited to participate in this validation study. The first 151 respondents were included. Validation participants completed the web-based version of the FSFI followed by a mailed paper-based version. Demographic data were collected for all subjects. Scores were compared using the paired t test and the intraclass correlation coefficient. One hundred fifty-one subjects completed both web- and paper-based versions of the FSFI. Those subjects participating in the validation study did not differ in demographics or FSFI scores from the remaining subjects in the general population study. Total web-based and paper-based FSFI scores were not significantly different (mean 20.31 and 20.29 respectively, p = 0.931). The six domains or subscales of the FSFI were similar when comparing web and paper scores. Finally, intraclass correlation analysis revealed a high degree of correlation between total and subscale scores, r = 0.848-0.943, p < 0.001. Web-based administration of the FSFI is a valid alternative to the paper-based version.

Despite widespread efforts to promote advance directives (ADs), completion rates remain low. Making Your Wishes Known: Planning Your Medical Future (MYWK) is an interactive computer program that guides individuals through the process of advance care planning, explaining health conditions and interventions that commonly involve life or death decisions, helps them articulate their values/goals, and translates users' preferences into a detailed AD document. The purpose of this study was to demonstrate that (in the absence of major life changes) the AD generated by MYWK reliably reflects an individual's values/preferences. English speakers ≥30 years old completed MYWK twice, 4 to 6 weeks apart. Reliability indices were assessed for three AD components: General Wishes; Specific Wishes for treatment; and Quality-of-Life values (QoL). Twenty-four participants completed the study. Both the Specific Wishes and QoL scales had high internal consistency in both time periods (Knuder Richardson formula 20 [KR-20]=0.83-0.95, and 0.86-0.89). Test-retest reliability was perfect for General Wishes (κ=1), high for QoL (Pearson's correlation coefficient=0.83), but lower for Specific Wishes (Pearson's correlation coefficient=0.57). MYWK generates an AD where General Wishes and QoL (but not Specific Wishes) statements remain consistent over time.

The purpose of this study was to examine the validity of a computerized 24-hour physical activity recall instrument (24PAR). Participants (n=20) wore 2 pattern-recognition activity monitors (an IDEEA and a SenseWear Pro Armband) for a 24-hour period and then completed the 24PAR the following morning. Participants completed 2 trials, 1 while maintaining a prospective diary of their activities and 1 without a diary. The trials were counterbalanced and completed within a week from each other. Estimates of energy expenditure (EE) and minutes of moderate-to-vigorous physical activity (MVPA) were compared with the criterion measures using 3-way (method by gender by trial) mixed-model ANOVA analyses. For EE, pairwise correlations were high (r>.88), and there were no differences in estimates across methods. Estimates of MVPA were more variable, but correlations were still in the moderate to high range (r>.57). Average activity levels were significantly higher on the logging trial, but there was no significant difference in the accuracy of self-report on days with and without logging. The results of this study support the overall utility of the 24PAR for group-level estimates of daily EE and MVPA.

Audience response systems (ARS) are increasingly popular; however, their contribution to education is not completely clear. Our study found that scores from review quizzes delivered by an ARS correlate with in-training exam (ITE) scores and are viewed positively by residents. This information may be useful in identifying poor performers early so that targeted educational interventions can be made. The objective was to determine if scores on review quizzes delivered by an ARS correlate with ITE scores and to obtain participant feedback on use of the ARS for ITE preparation. This was a prospective observational study of emergency medicine (EM) residents at six accredited EM residency programs. Subjects included residents who had taken previous ITEs. Subjects participated in bimonthly review sessions using an ARS. Twelve review quizzes were administered, each consisting of 10 multiple-choice questions. After the ITE, subjects completed an attitudinal survey consisting of six Likert-scale items and one "yes/no" item. We used a mixed linear model to analyze the data, accounting for prior 2012 ITE scores and nesting due to institution. Among 192 participants, 135 (70.3%) completed the ITE in both 2012 and 2013; we analyzed their data for the first objective. Results from the mixed linear model indicate that the total mean score on the review quizzes was a significant [t(127) = 6.68; p < 0.001] predictor of the 2013 ITE after controlling for the 2012 ITE score. One hundred forty-six (76.0%) participants completed the attitudinal survey; 96% of respondents stated that they would like ARS to be used more often in resident education. Respondents felt the sessions aided in learning (mean 7.7/10), assisted in preparation for the ITE (mean 6.7/10), and helped identify content areas of weakness (mean 7.6/10). Our results suggest that scores from review quizzes delivered by an audience response system correlate with in-training exam scores and is viewed positively by residents.

Correlation and agreement: overview and clarification of competing concepts and measures.

Agreement and correlation are widely-used concepts that assess the association between variables. Although similar and related, they represent completely different notions of association. Assessing agreement between variables assumes that the variables measure the same construct, while correlation of variables can be assessed for variables that measure completely different constructs. This conceptual difference requires the use of different statistical methods, and when assessing agreement or correlation, the statistical method may vary depending on the distribution of the data and the interest of the investigator. For example, the Pearson correlation, a popular measure of correlation between continuous variables, is only informative when applied to variables that have linear relationships; it may be non-informative or even misleading when applied to variables that are not linearly related. Likewise, the intraclass correlation, a popular measure of agreement between continuous variables, may not provide sufficient information for investigators if the nature of poor agreement is of interest. This report reviews the concepts of agreement and correlation and discusses differences in the application of several commonly used measures.

Gender-dependent differences in sensation seeking and social interaction are correlated with saliva testosterone titre in adolescents.

2006-06-01

In the present study, we tested the hypothesis that gender - dependent differences in novelty seeking, leadership, and sympathy might correlate with testosterone titre. Since several studies report that the impact of testosterone on personality traits is more visible under emotional challenging situations, we harvested saliva testosterone upon an anticipated stressor (academic examination) and under basal conditions. 19 female and 23 male adolescents (17 to 19 years of age) completed standardized questionnaires on sensation seeking, anxiety, and social interaction. Two weeks later, they had to write an anticipated, rigorous examination in mathematics in their school. Before and after the examination, saliva had been harvested from each subject and testosterone titre has been estimated. Saliva testosterone was quantified using a luminescence immunoassay (LIA). Each subject completed questionnaires on sensations seeking according to Zuckerman (SSS - V), anxiety (STAI), and social interactions. Both genders showed an increase in their testosterone titre shortly after examination or announcement of test scores. A Spearman correlation coefficient indicated a significant correlation between testosterone titre and sensation seeking subscales in female but not in male subjects. Analysis of social interactions revealed that peers regarded male subjects, who had high testosterone titres, as leaders but not as likeable individuals, whereas they regarded female subjects, who had high testosterone titres, not as leaders but as highly likeable individuals. Theses findings strongly suggest that testosterone has gender specific effects on novelty seeking, dominance, and sympathy.

This study evaluated the correlations between spiritual beliefs and health-related quality of life (HRQOL) of hemodialysis (HD) patients in Taiwan. Participants had to complete two questionnaires: the 36-item Short Form Health Survey Questionnaire and the Royal Free Interview for Spiritual and Religious Beliefs. They were then divided into three groups according to their strength of spiritual beliefs-having no, weak, or strong beliefs. Demographic, clinical, and laboratory data among groups were compared. Correlations between spiritual beliefs and HRQOL were then determined by the analysis of covariance and the post hoc Scheffe tests. Six hundred thirty-three patients completed the study. There were more women in the group of patients with strong beliefs (P = 0.005) and more less-educated patients in the group of patients with weak beliefs (P = 0.005). Patients with no or with strong spiritual beliefs had higher role physical (P = 0.01) and social functioning (SF) (P = 0.001) scores than patients with weak beliefs. After adjustment for gender, age, marital status, education, comorbidities, and time on dialysis, patients with no or with strong spiritual beliefs were found to have higher SF scores (P = 0.02) than patients with weak beliefs. HD patients with no or strong spiritual beliefs had higher SF HRQOL than those with weak spiritual beliefs.

Imiquimod is an excellent option for patients with actinic keratosis, although its use may be limited by the long course of treatment required (4 weeks) and the likelihood of local skin reactions. The objectives of the present study were to demonstrate the effectiveness of a 12-day course of imiquimod 5% for the treatment of actinic keratosis and to examine the association between treatment effectiveness and severity of local reactions. We included patients with at least 8 actinic keratoses treated with imiquimod 5% cream for 12 consecutive days. Local reactions were classified as mild, moderate, or severe. The statistical analysis of the association between local reactions and clinical response was based on the Pearson χ 2 test and the Spearman rank correlation test. Sixty-five patients completed the study. Complete response was recorded in 52.3% and partial response in 75.4%. We found a statistically significant association between severity of the local reaction and response to treatment in both the Pearson χ 2 test and the Spearman rank correlation test. A 12-day course of imiquimod 5% proved effective for the treatment of actinic keratosis. Severity of local reactions during treatment was correlated with clinical response. Copyright © 2017 AEDV.

Little research has examined the usefulness of positive well-being factors during pregnancy. Recent mindfulness research demonstrates that inconsistencies and the suitability of extant measures have yet to be examined in pregnancy. Effects of gratitude during pregnancy have yet to be examined despite consistently reported benefits in non-pregnant groups. The aims of this paper were to develop the Gratitude during Pregnancy (GDP) scale, validate the Mindfulness Awareness Attention Scale (MAAS) and examine the importance of gratitude and mindfulness during pregnancy. In study 1, 375 pregnant women completed gratitude and mindfulness measures. The one-factor structure of the MAAS was retained and demonstrated good reliability α = 0.88. Using exploratory factor analysis, an 18-item GDP scale was developed, demonstrating good reliability α = 0.89. The four GDP factors are as follows: general gratitude, physical changes, antenatal care and social support. In study 2, 87 pregnant women completed well-being questionnaires, including the GDP and MAAS. Gratitude correlated with positive affect, life satisfaction and pregnancy uplifts (p < .001); mindfulness correlated negatively with negative affect and pregnancy hassles (p < .001) and positively correlated with positive affect and pregnancy uplifts (p < .05). These findings highlight the importance of mindfulness and gratitude and provide a reliable means to measure both constructs during pregnancy.

Dynamics of correlations in long-range quantum systems follwing a quantum quench

NASA Astrophysics Data System (ADS)

Cevolani, Lorenzo; Carleo, Giuseppe; Sanchez-Palencia, Laurent

We study how and how fast correlations can spread in a quantum system abruptly driven out of equilibrium by a quantum quench. This protocol can be experimentally realized and it allow to address fundamental questions concerning the quasi-locality principle in isolated quantum systems with both short- and long-range interactions. We focus on two different models describing, respectively, lattice bosons, and spins. Our study is based on a combined approach, based on one hand on accurate many-body numerical calculations and on the other hand on a quasi-particle microscopic theory. We find that, for sufficiently fast decaying interaction potential the propagation is ballistic and the Lieb-Robinson bounds for long-range interactions are never attained. When the interactions are really long-range, the scenario is completely different in the two cases. In the bosonic system the locality is preserved and a ballistic propagation is still present while in the spin system an instantaneous propagation of correlations completely destroys locality. Using the microscopic point of view we can quantitatively describe all the different regimes, from instantaneous to ballistic, found in the spin model and we explain how locality is protected in the bosonic model leading to a ballistic propagation.

Oxford Elbow Score (OES) is a patient-reported questionnaire used to assess outcomes after elbow surgery. The aim of this study was to validate and adapt the OES into Persian language. After forward-backward translation of the OES into Persian, a total number of 92 patients after elbow surgeries completed the Persian OES along with the Persian DASH and SF-36. To assess test-retest reliability, 31 randomly selected patients (34%) completed the Persian OES again after three days while abstaining from all forms of therapeutic regimens. Reliability of the Persian OES was assessed by measuring intraclass correlation coefficient (ICC) for test-retest reliability and Cronbach's alpha for internal consistency. Spearman's correlation coefficient was used to test the construct validity. Cronbach's alpha coefficient was 0.92 showing excellent reliability. Cronbach's alpha for function, pain, and social-psychological subscales was 0.95, 0.86, and 0.85, respectively. Intraclass correlation coefficient (ICC) was 0.85 for the overall questionnaire and 0.90, 0.76, and 0.75 for function, pain, and social-psychological subscales, respectively. Construct validity was confirmed as the Spearman correlation between OES and DASH was 0.80. Persian OES is a valid and reliable patient-reported outcome measure to assess postsurgical elbow status in Persian speaking population.

Cognitive Correlates of Functional Abilities in Individuals with Mild Cognitive Impairment: Comparison of Questionnaire, Direct Observation and Performance-based Measures

2014-01-01

The relationship between and the cognitive correlates of several proxy measures of functional status were studied in a population with mild cognitive impairment (MCI). Participants were 51 individuals diagnosed with MCI and 51 cognitively healthy older adults (OA). Participants completed performance-based functional status tests, standardized neuropsychological tests, and performed eight activities of daily living (e.g., watered plants, filled medication dispenser) while under direct observation in a campus apartment. An informant interview about everyday functioning was also conducted. Compared to the OA control group, the MCI group performed more poorly on all proxy measures of everyday functioning. The informant-report of instrumental activities of daily living (IADL) did not correlate with the two performance-based measures; however, both the informant-report IADL and the performance-based everyday problem-solving test correlated with the direct observation measure. After controlling for age and education, cognitive predictors did not explain a significant amount of variance in the performance-based measures; however, performance on a delayed memory task was a unique predictor for the informant-report IADL, and processing speed predicted unique variance for the direct observation score. These findings indicate that differing methods for evaluating functional status are not assessing completely overlapping aspects of everyday functioning in the MCI population. PMID:24766574

Multireference second order perturbation theory with a simplified treatment of dynamical correlation.

PubMed

Xu, Enhua; Zhao, Dongbo; Li, Shuhua

2015-10-13

A multireference second order perturbation theory based on a complete active space configuration interaction (CASCI) function or density matrix renormalized group (DMRG) function has been proposed. This method may be considered as an approximation to the CAS/A approach with the same reference, in which the dynamical correlation is simplified with blocked correlated second order perturbation theory based on the generalized valence bond (GVB) reference (GVB-BCPT2). This method, denoted as CASCI-BCPT2/GVB or DMRG-BCPT2/GVB, is size consistent and has a similar computational cost as the conventional second order perturbation theory (MP2). We have applied it to investigate a number of problems of chemical interest. These problems include bond-breaking potential energy surfaces in four molecules, the spectroscopic constants of six diatomic molecules, the reaction barrier for the automerization of cyclobutadiene, and the energy difference between the monocyclic and bicyclic forms of 2,6-pyridyne. Our test applications demonstrate that CASCI-BCPT2/GVB can provide comparable results with CASPT2 (second order perturbation theory based on the complete active space self-consistent-field wave function) for systems under study. Furthermore, the DMRG-BCPT2/GVB method is applicable to treat strongly correlated systems with large active spaces, which are beyond the capability of CASPT2.

In this study, we first build two empirical cross-correlation matrices in the US stock market by two different methods, namely the Pearson’s correlation coefficient and the detrended cross-correlation coefficient (DCCA coefficient). Then, combining the two matrices with the method of random matrix theory (RMT), we mainly investigate the statistical properties of cross-correlations in the US stock market. We choose the daily closing prices of 462 constituent stocks of S&P 500 index as the research objects and select the sample data from January 3, 2005 to August 31, 2012. In the empirical analysis, we examine the statistical properties of cross-correlation coefficients, the distribution of eigenvalues, the distribution of eigenvector components, and the inverse participation ratio. From the two methods, we find some new results of the cross-correlations in the US stock market in our study, which are different from the conclusions reached by previous studies. The empirical cross-correlation matrices constructed by the DCCA coefficient show several interesting properties at different time scales in the US stock market, which are useful to the risk management and optimal portfolio selection, especially to the diversity of the asset portfolio. It will be an interesting and meaningful work to find the theoretical eigenvalue distribution of a completely random matrix R for the DCCA coefficient because it does not obey the Marčenko-Pastur distribution.

The aim of the current study was to investigate in-hospital falls among children with neurological or neurodevelopmental conditions and investigated associated child characteristics. A cross-sectional, correlational study design was used in this study. A total of 446 patients were enrolled in the study, of which 298 were admitted with neurological conditions and 148 with neurodevelopmental conditions. Intelligent quotient (IQ) was assessed according to age, and the Humpty Dumpty Falls Scale (HDFS) was completed and scored for each participant. The neurodevelopmental group showed higher HDFS total mean score (p = .001) compared to the neurological group. We found that fall rates are more frequent (p = .003) in the neurodevelopmental group (12.9%) compared with the neurological group (5.1%). In addition, we found that, in both groups, HDFS total mean score correlates negatively with children's age, gender and IQ. The results of this study suggest that the fall prevention programs must be implemented in children with neurodevelopmental conditions, not only in children with neurological conditions.

2014-01-01

Cervical cancer is a serious public health problem in South Africa. Even though the screening is free in health facilities in South Africa, the Pap smear uptake is very low. The objective of the study is to investigate the knowledge and beliefs of female university students in South Africa. A cross sectional study was conducted among university women in South Africa to elicit information about knowledge and beliefs, and screening history. A total of 440 students completed the questionnaire. The average age of the participants was 20.39 years (SD  = 1.71 years). Regarding cervical cancer, 55.2% (n = 243) had ever heard about it. Results indicated that only 15% (22/147) of the students who had ever had sex and had heard about cervical cancer had taken a Pap test. Pearson correlation analysis showed that cervical cancer knowledge had a significantly negative relationship with barriers to cervical cancer screening. Susceptibility and seriousness score were significantly moderately correlated with benefit and motivation score as well as barrier score. Self-efficacy score also had a moderate correlation with benefit and motivation score. Students who had had a Pap test showed a significantly lower score in barriers to being screened compared to students who had not had a Pap test. This study showed that educated women in South Africa lack complete information on cervical cancer. Students who had had a Pap test had significantly lower barriers to cervical cancer screening than those students who had not had a Pap test.

Psychometric properties of the Hebrew version of the Dutch Work Addiction Scale (DUWAS-10).

Littman-Ovadia, Hadassah; Balducci, Cristian; Ben-Moshe, Tali

2014-01-01

The present study examined the psychometric properties of the Hebrew version of the Dutch Work Addiction Scale (DUWAS-10), developed by Schaufeli, Shimazu, and Taris (2009). Three hundred fifty-one employees completed a questionnaire measuring workaholism; of these, 251 employees completed questionnaires measuring work engagement, job satisfaction, overcommitment, and burnout. The results confirmed the expected two-factor structure of workaholism: working excessively and working compulsively. Strong correlations were obtained between self-reports and peer-reports, and satisfactory correlations were obtained between the first and second administrations of the DUWAS-10. Furthermore, DUWAS-10 scores showed predictable relations with actual number of hours worked per week, work engagement, job satisfaction, overcommitment, and burnout. Interestingly, despite working fewer hours per week, women reported higher levels of workaholism in comparison to men, and managers reported higher levels of workaholism in comparison to nonmanagerial employees.

The effect of priming a thin ideal on the subsequent perception of conceptually related body image words.

PubMed

Markis, Teresa A; McLennan, Conor T

2011-09-01

Our research examined the effects of thin ideal priming on the perception of body image words in participants without an eating disorder. Half of the participants were primed by viewing thin models, and half were primed with gender-neutral shoes. Subsequently, all participants (N=56) completed a Stroop task for three categories of words: neutral (BOOKS), shoe (CLOGS), and body (THIGHS). Lastly, all participants completed a body dissatisfaction questionnaire. We predicted that body dissatisfaction scores would be correlated with the Stroop effect. We found a significant correlation between body dissatisfaction and the body effect of slower color naming times for the body related words compared to the neutral words. Our study demonstrates that body dissatisfaction and a brief priming with thin models results in subsequent differences in performing a Stroop task in a non clinical population of female participants.

Disruptive behaviors in the classroom: initial standardization data on a new teacher rating scale.

PubMed

Burns, G L; Owen, S M

1990-10-01

This study presents initial standardization data on the Sutter-Eyberg Student Behavior Inventory (SESBI), a teacher-completed measure of disruptive classroom behaviors. SESBIs were completed on 1116 children in kingergarten through fifth grade in a rural eastern Washington school district. Various analyses (Cronbach's alpha, corrected item-total correlations, average interitem correlations, principal components analyses) indicated that the SESBI provides a homogeneous measure of disruptive behaviors. Support was also found for three factors within the scale (e.g., overt aggression, oppositional behavior, and attentional difficulties). While the child's age did not have a significant effect on the SESBI, the child's gender did have a significant effect on scale scores as well as on most of the items, with males being rated more problematic than females. The SESBI was also able to discriminate between children in treatment for behavioral problems or learning disabilities and children not in treatment.

Poor sleep quality is a common health problem for coronary artery bypass graft patients, however few studies have evaluated sleep quality during the period immediately following hospital discharge. The aim of this study was to investigate changes in sleep quality and emotional correlates in coronary artery bypass graft patients in Taiwan at 1 week and 1 month after hospital discharge. We used a descriptive correlational design for this study. One week after discharge, 87 patients who had undergone coronary artery bypass surgery completed two structured questionnaires: the Pittsburgh Sleep Quality Index and the Hospital Anxiety and Depression Scale. Three weeks later (1 month after discharge) the patients completed the surveys again. Pearson correlations, t-tests, ANOVA and linear multiple regression analysis were used to analyze the data. A majority of the participants had poor sleep quality at 1 week (82.8%) and 1 month (66.7%) post-hospitalization, based on the global score of the Pittsburgh Sleep Quality Index. Despite poor sleep quality at both time-points the sleep quality at 1 month was significantly better than at 1-week post hospitalization. Poorer sleep quality correlated with older age, poorer heart function, anxiety and depression. The majority of participants had normal levels of anxiety at 1 week (69.0%) and 1 month (88.5%) as measured by the Hospital Anxiety and Depression Scale. However, some level of depression was seen at 1 week (78.1%) and 1 month (59.7%). Depression was a significant predictor of sleep quality at 1 week; at 1 month after hospital discharge both anxiety and depression were significant predictors of sleep quality. Sleep quality, anxiety and depression all significantly improved 1 month after hospital discharge. However, more than half of the participants continued to have poor sleep quality and some level of depression. Health care personnel should be encouraged to assess sleep and emotional status in patients after coronary artery bypass surgery and offer them appropriate management strategies to improve sleep and reduce anxiety and depression.

Purpose: To determine clinical factors for predicting the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer. Methods and Materials: The study group consisted of 109 patients with esophageal cancer of T1-4 and Stage I-III who were treated with definitive radiotherapy and achieved a complete response of their primary lesion at Kyushu University Hospital between January 1998 and December 2007. Esophageal stenosis was evaluated using esophagographic images within 3 months after completion of radiotherapy. We investigated the correlation between esophageal stenosis after radiotherapy and each of the clinical factors with regard to tumors andmore » therapy. For validation of the correlative factors for esophageal stenosis, an artificial neural network was used to predict the esophageal stenotic ratio. Results: Esophageal stenosis tended to be more severe and more frequent in T3-4 cases than in T1-2 cases. Esophageal stenosis in cases with full circumference involvement tended to be more severe and more frequent than that in cases without full circumference involvement. Increases in wall thickness tended to be associated with increases in esophageal stenosis severity and frequency. In the multivariate analysis, T stage, extent of involved circumference, and wall thickness of the tumor region were significantly correlated to esophageal stenosis (p = 0.031, p < 0.0001, and p = 0.0011, respectively). The esophageal stenotic ratio predicted by the artificial neural network, which learned these three factors, was significantly correlated to the actual observed stenotic ratio, with a correlation coefficient of 0.864 (p < 0.001). Conclusion: Our study suggested that T stage, extent of involved circumference, and esophageal wall thickness of the tumor region were useful to predict the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer.« less

Drug-Eluting Beads Loaded With Doxorubicin (DEBDOX) Chemoembolisation Before Liver Transplantation for Hepatocellular Carcinoma: An Imaging/Histologic Correlation Study

Purpose Most transplant centers use chemoembolisation as locoregional bridge therapy for hepatocellular carcinoma (HCC) before liver transplantation (LT). Chemoembolisation using beads loaded with doxorubicin (DEBDOX) is a promising technique that enables delivery of a large quantity of drugs against HCC. We sought to assess the imaging–histologic correlation after DEBDOX chemoembolisation.Materials and Methods All consecutive patients who had undergone DEBDOX chemoembolisation before receiving liver graft for HCC were included. Tumour response was evaluated according to Response Evaluation Criteria in Solid Tumours (RECIST) and modified RECIST (mRECIST) criteria. The result of final imaging made before LT was correlated with histological data to predict tumourmore » necrosis.ResultsTwenty-eight patients underwent 43 DEBDOX procedures for 45 HCC. Therapy had a significant effect as shown by a decrease in the mean size of the largest nodule (p = 0.02) and the sum of viable part of tumour sizes according to mRECIST criteria (p < 0.001). An objective response using mRECIST criteria was significantly correlated with mean tumour necrosis ≥90 % (p = 0.03). A complete response using mRECIST criteria enabled accurate prediction of complete tumour necrosis (p = 0.01). Correlations using RECIST criteria were not significant.ConclusionOur data confirm the potential benefit of DEBDOX chemoembolisation as bridge therapy before LT, and they provide a rational basis for new studies focusing on recurrence-free survival after LT. Radiologic evaluation according to mRECIST criteria enables accurate prediction of tumour necrosis, whereas RECIST criteria do not.« less

Examination of the relationship between performance testing and psychological measures before and after a 12-week strength and conditioning program was the study's purpose. Female NCAA Division-III soccer (n = 28), field hockey (n = 28), and softball (n = 19) athletes completed pre- and post-testing held 12 weeks apart. On day 1, athletes completed informed consent, 3 psychological measures (Profile of Mood States [POMS], Physical Self Perception Profile [PSPP], and Athlete's Self Perception of Physical Abilities [ASPPA]), and 2 strength tests (1 repetition maximum [1RM] bench, 1RM back squat). Day 2 consisted of the 30-yd sprint, pro agility run (PRO), vertical jump (VJ), and standing long jump (SLJ). All sports improved (p < 0.01) in 1RM bench and squat and reported increases in perceived Physical Strength on the PSPP (p < 0.01). Soccer athletes improved (p < 0.01) in VJ, SLJ, and PRO (p < 0.05). No differences were found in POMS scores. The POMS scores indicated that the athletes were not overtrained or experiencing staleness. A series of correlations showed relationships between physical and psychological measures. Specifically, Physical Strength was correlated with 1RM upper-body (r = 0.49, p < 0.01) and lower-body (r = 0.42, p < 0.01) strength. The PSPP Physical Strength was correlated with ASPPA ratings of upper-body (r = 0.68, p < 0.01) and lower-body (r = 0.57, p < 0.01) strength. The PSPP Sport Competence correlated with ASPPA ratings of power (r = 0.45, p < 0.01) and PRO (r = 0.38, p < 0.05). The study's results highlight the benefits of strength and conditioning. Furthermore, these results demonstrate how physical changes are related to athletes' physical self-perceptions and self-assessment of ability within their teams.

Physical activity (PA) diaries reduce the recall error inherent in self-reported PA but are burdensome. The purpose of this study was to compare a cell phone-based diary with a paper diary and examine the reliability and validity of the cell phone diary. In a pilot study, 25 women and 23 men, age 45-65 yr, completed cell phone and paper PA diaries 4 d·wk(-1) for three consecutive weeks and a user satisfaction survey. In the subsequent validation study, 623 middle-age participants (52.5% women) were asked to complete the cell phone diary and wear an accelerometer for two 7-d periods, approximately 6 months apart. They also completed two PA questionnaires. Fitness, body mass index, and percent body fat were obtained as indirect validation criteria. Estimates of PA from the cell phone and paper diaries were similar (mean within person difference = -43.8 MET·min·d(-1) of total PA, SD = 360, P = 0.49, 7.4 min·d(-1) of moderate-vigorous PA, SD = 66, P = 0.53). Users preferred the cell phone diary over the paper diary (59.6% vs 35.4%). In the subsequent study, intraclass correlations for the cell phone diary ranged from 0.55 for light PA to 0.63 for vigorous PA. Although PA estimates from the cell phone diary were generally significantly higher than those from the accelerometer and the questionnaires, correlations for moderate and vigorous PA were moderate (ρ = 0.25-0.59 with the questionnaires and 0.27-0.35 with the accelerometer). The correlations between the cell phone diary and the indirect validation criteria were generally in the expected direction and of moderate magnitude. A cell phone-based PA diary is equivalent to a paper diary, acceptable to users, and a relatively reliable and valid approach to self-reported PA.

The aim of the present study was to investigate whether trainees' performance on a virtual reality angled laparoscope navigation task correlates with scores obtained on a validated conventional test of spatial ability. 56 participants of a surgery workshop performed an angled laparoscope navigation task on the Xitact LS 500 virtual reality Simulator. Performance parameters were correlated with the score of a validated paper-and-pencil test of spatial ability. Performance at the conventional spatial ability test significantly correlated with performance at the virtual reality task for overall task score (p < 0.001), task completion time (p < 0.001) and economy of movement (p = 0.035), not for endoscope travel speed (p = 0.947). In conclusion, trainees' performance in a standardized virtual reality camera navigation task correlates with their innate spatial ability. This VR session holds potential to serve as an assessment tool for trainees.

The study's purpose was to determine if parental dental functional health literacy related to child oral health. A secondary aim was to assess if errors in completing the questionnaire related to FHL and child oral health. Parents of pediatric clinic children (N = 101) completed questionnaires and dental caries indices were recorded. Higher FHL was negatively correlated with worse child caries (r = -0.23), but not subjective oral health. Mean FHL seemed to differ by skip pattern (p = 0.087), indicating it may be a potential FHL proxy.

Clerkship directors routinely evaluate medical students using multiple modalities, including faculty assessment of clinical performance and written examinations. Both forms of evaluation often play a prominent role in final clerkship grade. The degree to which these modalities correlate in an emergency medicine (EM) clerkship is unclear. We sought to correlate faculty clinical evaluations with medical student performance on a written, standardized EM examination of medical knowledge. This is a retrospective study of fourth-year medical students in a 4-week EM elective at one academic medical center. EM faculty performed end of shift evaluations of students via a blinded online system using a 5-point Likert scale for 8 domains: data acquisition, data interpretation, medical knowledge base, professionalism, patient care and communication, initiative/reliability/dependability, procedural skills, and overall evaluation. All students completed the National EM M4 Examination in EM. Means, medians, and standard deviations for end of shift evaluation scores were calculated, and correlations with examination scores were assessed using a Spearman's rank correlation coefficient. Thirty-nine medical students with 224 discrete faculty evaluations were included. The median number of evaluations completed per student was 6. The mean score (±SD) on the examination was 78.6% ± 6.1%. The examination score correlated poorly with faculty evaluations across all 8 domains (ρ 0.074-0.316). Faculty evaluations of medical students across multiple domains of competency correlate poorly with written examination performance during an EM clerkship. Educators need to consider the limitations of examination score in assessing students' ability to provide quality patient clinical care. Copyright © 2016 Elsevier Inc. All rights reserved.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is a treatment option in patients with carcinomatosis from high-grade appendiceal (HGA) primaries. It is unknown if there is a Peritoneal Carcinomatosis Index (PCI) upper limit above which a complete CRS/HIPEC does not assure long-term survival. Retrospective analysis from three centers was performed. The PCI was used to grade volume of of disease. Survival in relation to PCI was studied on patients with complete cytoreduction. Overall, 521 HGA patients underwent CRS/HIPEC from 1993 to 2015, with complete CRS being achieved in 50% (260/622). Mean PCI was 14.8 (standard deviation 8.7, range 0-36). Median survival for the complete CRS cohort was 6.1 years, while 5- and 10-year survival was 51.7% (standard error [SE] 4.6) and 36.1% (SE 6.3), respectively. Arbitrary cut-off PCI limits with 5-point splits (p = 0.63) were not predictive of a detrimental effect on survival as long as a complete CRS was achieved. A linear effect of the PCI on survival (p = 0.62) was not observed, and single-point PCI cohort splits within a PCI range of < 5 to > 10 were not predictive of survival for complete CRS patients. The PCI correlated with the ability to achieve a complete CRS, with a mean PCI of 14.7 (8.7) for completeness of cytoreduction (CC)0, 22.3 (7.8) for CC1 and 26.1 (9.5) for CC2/3 resections (p = 0.0001, hazard ratio 1.12, 95% confidence interval 1.09), with an HR of 1.15 for each 1-unit increase in the PCI score. Only 21% of the cohort achieved a complete CRS with a PCI ≥ 21. The PCI correlates with the ability to achieve a complete CRS in carcinomatosis from HGA. PCI is not associated with survival as long as a complete CRS can be achieved.

Database quality measurement should be considered a mandatory step to ensure an adequate level of confidence in data used for research and quality improvement. Several metrics have been described in the literature, but no standardized approach has been established. We aimed to describe a methodological approach applied to measure the quality and inter-rater reliability of a regional multicentric thoracic surgical database (Paulista Lung Cancer Registry). Data from the first 3 years of the Paulista Lung Cancer Registry underwent an audit process with 3 metrics: completeness, consistency, and inter-rater reliability. The first 2 methods were applied to the whole data set, and the last method was calculated using 100 cases randomized for direct auditing. Inter-rater reliability was evaluated using percentage of agreement between the data collector and auditor and through calculation of Cohen's κ and intraclass correlation. The overall completeness per section ranged from 0.88 to 1.00, and the overall consistency was 0.96. Inter-rater reliability showed many variables with high disagreement (>10%). For numerical variables, intraclass correlation was a better metric than inter-rater reliability. Cohen's κ showed that most variables had moderate to substantial agreement. The methodological approach applied to the Paulista Lung Cancer Registry showed that completeness and consistency metrics did not sufficiently reflect the real quality status of a database. The inter-rater reliability associated with κ and intraclass correlation was a better quality metric than completeness and consistency metrics because it could determine the reliability of specific variables used in research or benchmark reports. This report can be a paradigm for future studies of data quality measurement. Copyright © 2018 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Correlates of the multidimensional construct of hypnotizability: paranormal belief, fantasy proneness, magical ideation, and dissociation.

Hypnotizability is a multifaceted construct that may relate to multiple aspects of personality and beliefs. This study sought to address 4 known correlates of hypnotizability to aid in its understanding. Eighty undergraduates completed the Magical Ideation Scale (MIS), the Creative Experiences Questionnaire (CEQ), the Australian Sheep-Goat Scale (ASGS), and the Dissociative Experiences Scale (DES) and then were administered the Creative Imagination Scale (CIS). All 5 scales were significantly correlated. Participants higher in hypnotizability scored higher on the CEQ and the MIS. The findings demonstrate the influence of fantasy proneness and magical thinking on hypnotizability and support the theory that hypnotizability is a complex interaction of multiple traits.

We investigated the extent of cortical thinning in U.S. Veterans exposed to combat who varied in the severity of their posttraumatic stress disorder (PTSD) symptoms. In addition, we explored the neural correlates of PTSD symptom dimensions and the interactive effects of combat exposure and PTSD upon cortical thickness. Sixty-nine combat exposed Veterans completed high-resolution magnetic resonance imaging (MRI) scans to estimate cortical thickness. The Clinician Administered PTSD Scale (CAPS) and Combat Exposure Scale (CES) assessments were completed to measure current PTSD and historical combat severity, respectively. PTSD symptom dimensions (numbing, avoidance, reexperiencing, anxious arousal, and dysphoric arousal) were studied. Vertex-wise whole cerebrum analyses were conducted. We found widespread negative correlations between CAPS severity and cortical thickness, particularly within the prefrontal cortex. This prefrontal correlation remained significant after controlling for depression severity, medication status, and other potential confounds. PTSD dimensions, except anxious arousal, negatively correlated with cortical thickness in various unique brain regions. CES negatively correlated with cortical thickness in the left lateral prefrontal, regardless of PTSD diagnosis. A significant interaction between CES and PTSD diagnosis was found, such that CES negatively correlated with cortical thickness in the non-PTSD, but not in the PTSD, participants. The results underscore the severity of cortical thinning in U.S. Veterans suffering from high level of PTSD symptoms, as well as in Veterans with no PTSD diagnosis but severe combat exposure. The latter finding raises considerable concerns about a concealed injury potentially related to combat exposure in the post-9/11 era. PMID:28279623

To analyze the construct validity of three methods to assess the clinical performances of internal medicine clerks. A multitrait-multimethod (MTMM) study was conducted at the Case Western Reserve University School of Medicine to determine the convergent and divergent validity of a clinical evaluation form (CEF) completed by faculty and residents, an objective structured clinical examination (OSCE), and the medicine subject test of the National Board of Medical Examiners. Three traits were involved in the analysis: clinical skills, knowledge, and personal characteristics. A correlation matrix was computed for 410 third-year students who completed the clerkship between August 1988 and July 1991. There was a significant (p < .01) convergence of the four correlations that assessed the same traits by using different methods. However, the four convergent correlations were of moderate magnitude (ranging from .29 to .47). Divergent validity was assessed by comparing the magnitudes of the convergence correlations with the magnitudes of correlations among unrelated assessments (i.e., different traits by different methods). Seven of nine possible coefficients were smaller than the convergent coefficients, suggesting evidence of divergent validity. A significant CEF method effect was identified. There was convergent validity and some evidence of divergent validity with a significant method effect. The findings were similar for correlations corrected for attenuation. Four conclusions were reached: (1) the reliability of the OSCE must be improved, (2) the CEF ratings must be redesigned to further discriminate among the specific traits assessed, (3) additional methods to assess personal characteristics must be instituted, and (4) several assessment methods should be used to evaluate individual student performances.

The Application of a Technique for Vector Correlation to Problems in Meteorology and Oceanography.

In a recent study, Crosby et al. proposed a definition for vector correlation that has not been commonly used in meteorology or oceanography. This definition has both a firm theoretical basis and a rather complete set of desirable statistical properties. In this study, the authors apply the definition to practical problems arising in meteorology and oceanography. In the first of two case studies, vector correlations were calculated between subsurface currents for five locations along the southeastern shore of Lake Erie. Vector correlations for one sample size were calculated for all current meter combinations, first including the seiche frequency and then with the seiche frequency removed. Removal of the seiche frequency, which was easily detected in the current spectra, had only a small effect on the vector correlations. Under reasonable assumptions, the vector correlations were in most cases statistically significant and revealed considerable fine structure in the vector correlation sequences. In some cases, major variations in vector correlation coincided with changes in surface wind. The vector correlations for the various current meter combinations decreased rapidly with increasing spatial separation. For one current meter combination, canonical correlations were also calculated; the first canonical correlation tended to retain the underlying trend, whereas the second canonical correlation retained the peaks in the vector correlations.In the second case study, vector correlations were calculated between marine surface winds derived from the National Meteorological Center's Global Data Assimilation System and observed winds acquired from the network of National Data Buoy Center buoys that are located off the continental United States and in the Gulf of Alaska. Results of this comparison indicated that 1) there was a significant decrease in correlation between the predicted and observed winds with increasing forecast interval out to 72 h, 2) the technique provides a sensitive indicator for detecting bad buoy reports, and 3) there was no obvious seasonal cycle in the monthly vector correlations for the period of observation.

Esophageal emptying assessed at the 'timed barium' esophagogram correlates well with symptomatic outcomes after pneumatic dilation for esophageal achalasia, although 30% of patients with satisfactory outcome exhibit partial improvement in emptying. The aim of the study was to investigate any correlation of esophageal emptying to symptomatic response after laparoscopic Heller's myotomy and Dor's fundoplication. 'Bread and barium' (transit time of a barium opaque bread bolus) and 'timed barium' (height of esophageal barium column 5 minutes after ingestion of 200-250 mL of barium suspension) esophagogram was used to assess esophageal emptying in 73 patients with esophageal achalasia before 1 and 5 years (31 cases) after laparoscopic myotomy and anterior fundoplication. Symptoms assessment was based to a specific score. At 1-year follow-up, excellent and good symptomatic results were obtained in 95% of the cases. Esophageal maximum diameter, esophageal transit time, and esophageal barium column were significantly correlated to each other and to symptom score postoperatively (P < 0.001). Complete and partial (<90% and 50-90% postoperative reduction in barium column, respectively) emptying was seen in 55% and 31% of patients with excellent result. Patients with a pseudodiverticulum postoperatively had a more delayed esophageal emptying than those without. Symptomatic outcome and esophageal emptying did not deteriorate at 5-year follow-up. Esophageal emptying assessed by 'barium and bread' and 'timed barium' esophagogram correlated well with symptomatic outcome after laparoscopic myotomy for esophageal achalasia. Complete symptomatic relief does not necessarily reflect complete esophageal emptying. Outcomes do not deteriorate by time. Because of wide availability, esophagogram can be applied in follow-up of postmyotomy patients in conjunction with symptomatic evaluation. © 2011 Copyright the Authors.

Neural correlate of human inductive reasoning process is still unclear. Number series and letter series completion are two typical inductive reasoning tasks, and with a common core component of rule induction. Previous studies have demonstrated that different strategies are adopted in number series and letter series completion tasks; even the underlying rules are identical. In the present study, we examined cortical activation as a function of two different reasoning strategies for solving series completion tasks. The retrieval strategy, used in number series completion tasks, involves direct retrieving of arithmetic knowledge to get the relations between items. The procedural strategy, used in letter series completion tasks, requires counting a certain number of times to detect the relations linking two items. The two strategies require essentially the equivalent cognitive processes, but have different working memory demands (the procedural strategy incurs greater demands). The procedural strategy produced significant greater activity in areas involved in memory retrieval (dorsolateral prefrontal cortex, DLPFC) and mental representation/maintenance (posterior parietal cortex, PPC). An ACT-R model of the tasks successfully predicted behavioral performance and BOLD responses. The present findings support a general-purpose dual-process theory of inductive reasoning regarding the cognitive architecture. Copyright © 2014 Elsevier B.V. All rights reserved.

Investigate factors associated with employee participation rates in health risk assessments. This cross-sectional study using multiple regression analyzed data from 124 employers with 882,275 eligible employees who completed 344,825 health and productivity assessments (HPAs). Incentive value and Communications and Organizational Commitment Level (Com/Org Level) were the strongest predictors of HPA completion rates. Employer size and a Gateway Model were also significant predictors. In addition, a correlation of variables showed other important relationships. To achieve a 50% HPA completion rate, employers with a low Com/Org Level will need an incentive value of approximately $120 whereas employers with a high Com/Org Level only need approximately $40--a difference of $80 dollars. This applied study offers empirical evidence to help employers increase their employees' participation in health risk assessments.

Excitonic instability in a strongly correlated system: A slave rotor approach

NASA Astrophysics Data System (ADS)

Pradhan, Subhasree; Taraphder, A.

2018-05-01

Exciton formation and condensation in a two band correlated model is studied using slave rotor mean field (SRMF) theory. In the SRMF theory, charge and spin degrees are treated as independent degrees of freedom. Using this, we capture the effective many body scales beyond conventional mean-field theory. While the formation of exciton is favoured by the hybridization, it is strongy influenced by the Coulomb repulsion between electrons in the two bands. Beyond a critical value of hybridization, there is complete coheherence among the electrons and holes signalling a condensation of excitons.

Another nail in the coffin for learning styles? Disparities among undergraduate anatomy students' study strategies, class performance, and reported VARK learning styles.

The concept and existence of learning styles has been fraught with controversy, and recent studies have thrown their existence into doubt. Yet, many students still hold to the conventional wisdom that learning styles are legitimate, and may adapt their outside of class study strategies to match these learning styles. Thus, this study aims to assess if undergraduate anatomy students are more likely to utilize study strategies that align with their hypothetical learning styles (using the VARK analysis from Fleming and Mills, , Improve Acad. 11:137-155) and, if so, does this alignment correlate with their outcome in an anatomy course. Relatedly, this study examines whether students' VARK learning styles are correlated with course outcomes regardless of the students' study strategies, and whether any study strategies are correlated with course outcomes, regardless of student-specific VARK results. A total of 426 anatomy students from the 2015 and 2016 Fall semesters completed a study strategies survey and an online VARK questionnaire. Results demonstrated that most students did not report study strategies that correlated with their VARK assessment, and that student performance in anatomy was not correlated with their score in any VARK categories. Rather, some specific study strategies (irrespective of VARK results), such as use of the virtual microscope, were found to be positively correlated with final class grade. However, the alignment of these study strategies with VARK results had no correlation with anatomy course outcomes. Thus, this research provides further evidence that the conventional wisdom about learning styles should be rejected by educators and students alike.

To better understand the relationship between mindfulness and depression, we studied normal young adults (n=27) who completed measures of dispositional mindfulness and depressive symptomatology, which were then correlated with: a) Rest: resting neural activity during passive viewing of a fixation cross, relative to a simple goal-directed task (shape-matching); and b) Reactivity: neural reactivity during viewing of negative emotional faces, relative to the same shape-matching task. Dispositional mindfulness was negatively correlated with resting activity in self-referential processing areas, while depressive symptomatology was positively correlated with resting activity in similar areas. In addition, dispositional mindfulness was negatively correlated with resting activity in the amygdala, bilaterally, while depressive symptomatology was positively correlated with activity in the right amygdala. Similarly, when viewing emotional faces, amygdala reactivity was positively correlated with depressive symptomatology and negatively correlated with dispositional mindfulness, an effect that was largely attributable to differences in resting activity. These findings indicate that mindfulness is associated with intrinsic neural activity and that changes in resting amygdala activity could be a potential mechanism by which mindfulness-based depression treatments elicit therapeutic improvement.

2018-05-01

The objective of the present work is to study the two-phase pressure drop in helical coils. Literature on the two-phase pressure drop in a helical coil suggests the complexity in flow boiling inside a helical coil due to secondary flow. Most of correlations reported in the literature on the two-phase pressure drop in a helical coil are limited to a specific operating range. No general correlation is available for a helical coil which is applicable for all fluids. In the present study, an experimental databank collected containing a total of 832 data points includes the data from the present study and from the literature. The data includes diabatic pressure drop of two fluids namely water and R123. Data covers a range of parameters namely a mass flux of 120-2058 kg/m2 s, a heat flux of 18-2831 kW/m2, an exit quality of 0.03-1, a density ratio of 32-1404 and a coil to tube diameter ratio of 14-58. The databank is compared with eighteen empirical correlations which include well referred correlations of straight tubes and the available correlations of helical coils. The straight tube correlations are not working well for the present data set. The helical coil correlations work reasonably well for the present databank. A correlation is suggested to predict the two-phase pressure drop in helical coils. The present study suggests that the influence of a helical coil is completely included in the single phase pressure drop correlation for helical coils.

Introduction: Tinnitus can have a significant effect on an individual’s quality of life, and is very difficult quantify. One of the most popular questionnaires used in this area is the Tinnitus Handicap Inventory (THI). The aim of this study was to determine the reliability and validity of a Persian translation of the Tinnitus Handicap Inventory (THI-P). Materials and Methods: This prospective clinical study was performed in the Otolaryngology Department of Guilan University of Medical Sciences, Iran. A total of 102 patients aged 23–80 years with tinnitus completed the (THI-P). The patients were instructed to complete the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). Audiometry was performed. Eight-five patients were asked to complete the THI-P for a second time 7–10 days after the initial interview. We assessed test–retest reliability and internal reliability of the THI-P. Validity was assessed by analyzing the THI-P of patients according to their age, tinnitus duration and psychological distress (BDI and STAI). A factor analysis was computed to verify if three subscales (functional, emotional, and catastrophic) represented three distinct variables. Results: Test–retest correlation coefficient scores were highly significant. The THI-P and its subscales showed good internal consistency reliability (α = 0.80 to 0.96). High-to-moderate correlations were observed between THI-P and psychological distress and tinnitus symptom ratings. A confirmatory factor analysis failed to validate the three subscales of THI, and high inter-correlations found between the subscales question whether they represent three distinct factors. Conclusion: The results suggest that the THI-P is a reliable and valid tool which can be used in a clinical setting to quantify the impact of tinnitus on the quality of life of Iranian patients.

To validate the pediatric Patient-Reported Outcomes Measurement Information System short forms (PROMIS-SFs) in childhood-onset systemic lupus erythematosus (SLE) in a clinical setting. At 3 study visits, childhood-onset SLE patients completed the PROMIS-SFs (anger, anxiety, depressive symptoms, fatigue, physical function-mobility, physical function-upper extremity, pain interference, and peer relationships) using the PROMIS assessment center, and health-related quality of life (HRQoL) legacy measures (Pediatric Quality of Life Inventory, Childhood Health Assessment Questionnaire, Simple Measure of Impact of Lupus Erythematosus in Youngsters [SMILEY], and visual analog scales [VAS] of pain and well-being). Physicians rated childhood-onset SLE activity on a VAS and completed the Systemic Lupus Erythematosus Disease Activity Index 2000. Using a global rating scale of change (GRC) between study visits, physicians rated change of childhood-onset SLE activity (GRC-MD1: better/same/worse) and change of patient overall health (GRC-MD2: better/same/worse). Questionnaire scores were compared in support of validity and responsiveness to change (external standards: GRC-MD1, GRC-MD2). In this population-based cohort (n = 100) with a mean age of 15.8 years (range 10-20 years), the PROMIS-SFs were completed in less than 5 minutes in a clinical setting. The PROMIS-SF scores correlated at least moderately (Pearson's r ≥ 0.5) with those of legacy HRQoL measures, except for the SMILEY. Measures of childhood-onset SLE activity did not correlate with the PROMIS-SFs. Responsiveness to change of the PROMIS-SFs was supported by path, mixed-model, and correlation analyses. To assess HRQoL in childhood-onset SLE, the PROMIS-SFs demonstrated feasibility, internal consistency, construct validity, and responsiveness to change in a clinical setting. © 2016, American College of Rheumatology.

Inter-Clade Protection Offered by Mw-Adjuvanted Recombinant HA, NP Proteins, and M2e Peptide Combination Vaccine in Mice Correlates with Cellular Immune Response.

We documented earlier that Mw (heat-killed suspension of Mycobacterium indicus pranii ) adjuvant when used with conserved antigens, nucleoprotein (NP), and ectodomain of matrix (M2) protein (M2e) provided complete protection against homologous (clade 2.2) virus challenge in mice. The present study extends these observations to inter-clade challenge (clade 2.3.2.1) H5N1 virus and attempts to understand preliminary immunologic basis for the observed protection. Female BALB/c mice immunized with a single or two doses of vaccine formulations (clade 2.2 antigens) were challenged with 100LD50 homologous or heterologous (clade 2.3.2.1) virus. To understand the preliminary immunologic mechanism, we studied proportions of selected immune cell types, immune response gene expression, and Th1/Th2 cytokines induced by antigen-stimulated splenocytes from immunized mice, at different time points. Complete protection was conferred by Mw-HA, Mw-HA + NP, and Mw-HA + NP + M2e against homologous challenge. The protection correlated with IgG2a antibody titers indicating important role of Th1 response. Despite high inter-cladal antigenic differences, complete protection against the heterologous strain was achieved with Mw-HA + NP + M2e. Of note, a single dose with higher antigen concentrations (50 µg HA + 50 μg NP + 50 μg M2e) led to 80% protection against clade 2.3.2.1 strain. The protection conferred by Mw-HNM correlated with induction of IFN-γ, CD8 + T cytotoxic cells, and CD4 + T helper cells. Mw-adjuvanted HA + NP + M2e combination represents a promising vaccine candidate deserving further evaluation.

Cross-sectional validation study. To examine the construct and concurrent validity of the International Spinal Cord Injury (SCI) Quality of Life (QoL) Basic Data Set. Dutch community. People 28-65 years of age, who obtained their SCI between 18 and 35 years of age, were at least 10 years post SCI and were wheelchair users in daily life. MEASURE(S): The International SCI QoL Basic Data Set consists of three single items on satisfaction with life as a whole, physical health and psychological health (0=complete dissatisfaction; 10=complete satisfaction). Reference measures were the Mental Health Inventory-5 and three items of the World Health Organization Quality of Life measure. Data of 261 participants were available. Mean time after SCI was 24.1 years (s.d. 9.1); 90.4% had a traumatic SCI, 81.5% a motor complete SCI and 40% had tetraplegia. Mean age was 47.9 years (s.d. 8.8) and 73.2% were male. Mean scores were 6.9 (s.d. 1.9) for general QoL, 5.8 (s.d. 2.2) for physical health and 7.1 (s.d. 1.9) for psychological health. No floor or ceiling effects were found. Strong inter-correlations (0.48-0.71) were found between the items, and Cronbach's alpha of the scale was good (0.81). Correlations with the reference measures showed the strongest correlations between the WHOQOL general satisfaction item and general QoL (0.64), the WHOQOL health and daily activities items and physical health (0.69 and 0.60) and the Mental Health Inventory-5 and psychological health (0.70). This first validity study of the International SCI QoL Basic Data Set shows that it appears valid for persons with SCI.

Occupational therapists often assess the motor skill performance of children referred to them as part of the assessment process. This study investigated whether children's, parents' and teachers' perceptions of children's motor skills using valid and reliable self/informant-report questionnaires were associated with and predictive of children's actual motor performance, as measured by a standardised performance-based motor skill assessment. Fifty-five typically developing children (8-12 years of age), their parents and classroom teachers were recruited to participate in the study. The children completed the Physical Self-Description Questionnaire (PSDQ) and the Self-Perception Profile for Children. The parents completed the Developmental Profile III (DP-III) and the Developmental Coordination Disorder Questionnaire, whereas the teachers completed the Developmental Coordination Disorder Questionnaire and the Teacher's Rating Scale of Child's Actual Behavior. Children's motor performance composite scores were determined using the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2). Spearman's rho correlation coefficients were calculated to identify if significant correlations existed and multiple linear regression was used to identify whether self/informant report data were significant predictors of children's motor skill performance. The child self-report scores had the largest number of significant correlations with the BOT-2 composites. Regression analysis found that the parent report DP-III Physical subscale was a significant predictor of the BOT-2 Manual Coordination composite and the child-report questionnaire PSDQ. Endurance subscale was a significant predictor of the BOT-2 Strength and Agility composite. The findings support the use of top-down assessment methods from a variety of sources when evaluating children's motor abilities. © 2016 Occupational Therapy Australia.

The commonly used time scales in entrainment-mixing studies are examined in this paper to seek the most appropriate one, based on aircraft observations of cumulus clouds from the RACORO campaign and numerical simulations with the Explicit Mixing Parcel Model. The time scales include: τ evap, the time for droplet complete evaporation; τ phase, the time for saturation ratio deficit (S) to reach 1/e of its initial value; τ satu, the time for S to reach -0.5%; τ react, the time for complete droplet evaporation or S to reach -0.5%. It is found that the proper time scale to use dependsmore » on the specific objectives of entrainment-mixing studies. First, if the focus is on the variations of liquid water content (LWC) and S, then τ react for saturation, τ satu and τ phase are almost equivalently appropriate, because they all represent the rate of dry air reaching saturation or of LWC decrease. Second, if one focuses on the variations of droplet size and number concentration, τ react for complete evaporation and τ evap are proper because they characterize how fast droplets evaporate and whether number concentration decreases. Moreover, τ react for complete evaporation and τ evap are always positively correlated with homogeneous mixing degree (ψ), thus the two time scales, especially τ evap, are recommended for developing parameterizations. However, ψ and the other time scales can be negatively, positively, or not correlated, depending on the dominant factors of the entrained air (i.e., relative humidity or aerosols). Third and finally, all time scales are proportional to each other under certain microphysical and thermodynamic conditions.« less

2011-12-01

To develop and test a user-friendly questionnaire for rapidly assessing quality of life (QOL) in thyroid eye disease (TED). A three-item questionnaire, the TED-QOL, was designed and compared to the 16-item Graves Ophthalmopathy (GO)-QOL and the nine-item GO-Quality of Life Scale (QLS). 100 patients with TED were administered all three questionnaires on two occasions. Results were compared to clinical severity scores (Vision, Inflammation, Strabismus, Appearance (VISA) classification). Main outcomes were construct and criterion validity, test-retest reliability, duration, comprehension and completion rates. TED-QOL correlated strongly with the other questionnaires for corresponding items (Pearson correlation: appearance 0.71, 0.62; functioning 0.69, 0.66; overall QOL 0.53). Test-retest analysis demonstrated good reliability for all three questionnaires (intraclass correlations: TED-QOL 0.81, 0.74, 0.87; GO-QOL 0.81, 0.82; GO-QLS 0.74, 0.86, 0.67). TED-QOL was significantly faster to complete (1.6 min vs GO-QOL 3.1 min, GO-QLS 2.7 min, p<0.0001) and had a higher completion rate (100% vs GO-QOL 78%, GO-QLS 94%). There was only moderate correlation between items on all three questionnaires and VISA scores. The TED-QOL is rapid and easy to complete and analyse and has similar validity and reliability to longer questionnaires. All questionnaires showed only moderate correlation with disease severity, emphasising the discrepancy between objective and subjective assessments and the importance of measuring both.

The objectives of this correlational study were to explore whether the oral health-related quality of life (ohrqol) of adolescents/young adults with cleft lip/palate (CL/P) relates to their own and their parents' satisfaction with treatment and treatment outcomes. Data were collected using mailed surveys from 30 parents and 27 patients who completed CL/P treatment. Patients' ohrqol was assessed with the Michigan Oral Health-Related Quality of Life (MOHRQoL) Scale, treatment satisfaction with Kiyak's Post-Surgical Patient Satisfaction Questionnaire, and satisfaction with treatment outcomes with Noor and Musa's Cleft Evaluation Profile. Overall, patients reported a positive ohrqol. Their satisfaction scores ranged from low to high. Patient and parent treatment satisfaction was related, while their outcome satisfaction did not correlate. Patients' MOHRQoL scores correlated with parent and patient treatment satisfaction and parents' outcome satisfaction. Patients' MOHRQoL scores did not correlate with patients' outcome satisfaction. The patients' level of discomfort was strongly correlated with patients' and parents' treatment satisfaction and parents' outcome satisfaction. In conclusion, regardless of outcome satisfaction, young patients with CL/P report a quite positive ohrqol after treatment completion. There is a clear relationship between the ohrqol of these patients with CL/P and their own as well as their parents' treatment satisfaction assessments.

Trabecular plates and rods are important microarchitectural features in determining mechanical properties of trabecular bone. A complete volumetric decomposition of individual trabecular plates and rods was used to assess the orientation and morphology of 71 human trabecular bone samples. The ITS-based morphological analyses better characterize microarchitecture and help predict anisotropic mechanical properties of trabecular bone. Standard morphological analyses of trabecular architecture lack explicit segmentations of individual trabecular plates and rods. In this study, a complete volumetric decomposition technique was developed to segment trabecular bone microstructure into individual plates and rods. Contributions of trabecular type-associated morphological parameters to the anisotropic elastic moduli of trabecular bone were studied. Seventy-one human trabecular bone samples from the femoral neck (FN), tibia, and vertebral body (VB) were imaged using muCT or serial milling. Complete volumetric decomposition was applied to segment trabecular bone microstructure into individual plates and rods. The orientation of each individual trabecula was determined, and the axial bone volume fractions (aBV/TV), axially aligned bone volume fraction along each orthotropic axis, were correlated with the elastic moduli. The microstructural type-associated morphological parameters were derived and compared with standard morphological parameters. Their contributions to the anisotropic elastic moduli, calculated by finite element analysis (FEA), were evaluated and compared. The distribution of trabecular orientation suggested that longitudinal plates and transverse rods dominate at all three anatomic sites. aBV/TV along each axis, in general, showed a better correlation with the axial elastic modulus (r(2) = 0.95 approximately 0.99) compared with BV/TV (r(2) = 0.93 approximately 0.94). The plate-associated morphological parameters generally showed higher correlations with the corresponding standard morphological parameters than the rod-associated parameters. Multiple linear regression models of six elastic moduli with individual trabeculae segmentation (ITS)-based morphological parameters (adjusted r(2) = 0.95 approximately 0.98) performed equally well as those with standard morphological parameters (adjusted r(2) = 0.94 approximately 0.97) but revealed specific contributions from individual trabecular plates or rods. The ITS-based morphological analyses provide a better characterization of the morphology and trabecular orientation of trabecular bone. The axial loading of trabecular bone is mainly sustained by the axially aligned trabecular bone volume. Results suggest that trabecular plates dominate the overall elastic properties of trabecular bone.

Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response, it is unsuitable for surveillance of patients treated via a nonoperative approach. Incorporation of a "watchful waiting" strategy without establishing proper surveillance protocols and salvage strategies might result in poor local control.

Beyond evidence for an association, little is known about the mechanism linking creativity bipolar spectrum conditions. Theory suggests that ambition, which is heightened in bipolar disorder (BD) and associated with creativity in the general population, might be an important variable. The overarching aim of this project was to evaluate whether ambition is related to creativity among those with bipolar spectrum conditions. Across two studies, we examined correlations between a validated self-report measure of ambition, the WASSUP, and creativity. In Study One, 22 individuals diagnosed with BD who self-identified as highly creative completed the WASSUP and a measure of lifetime creative accomplishment. In Study Two, 221 undergraduates completed the WASSUP, a measure of mania risk (the Hypomanic Personality Scale, HPS) and a measure designed to assess creativity in business projects and tasks. In Study One, WASSUP scores were significantly elevated compared to normative levels in BD, and WASSUP scores were correlated with lifetime creative accomplishment within the artistic sample. In Study Two, mania risk was related to greater ambition and creativity, and ambition was also directly related to greater creativity. Both studies were limited by the reliance on self-reported ambition. Ambition could be one important component of creative success across the bipolar spectrum. Copyright © 2015 Elsevier B.V.

The aim of this study was to evaluate the proportion of completed treatments and to study the factors affecting the full mouth dental rehabilitation in pediatric patients treated by undergraduate students at the College of Dental Medicine Teaching Clinics, University of Sharjah. A retrospective study was conducted on 270 children aged less than 12 years (mean age 7.6, SD 2.04). Comprehensive dental rehabilitation reports of child patients that were completed by final year dental undergraduate students from the year 2009 to 2011 were reviewed. Data on complete history, oral examination, dental charting, and treatment plan were collected from pediatric dentistry case sheet. Dental caries was charted using WHO 1997 criteria. Dental treatment needs and completion of dental care delivered to children involved in this study were assessed using DMFT/deft scores. Percentages of treatment provided included completed restorations (94%) and space management (84%) in primary dentition, whereas 98% of restoration and 94% of required sealants were completed in permanent dentition. The percentage of completed dental treatment including sealant placement was 61%. Age of the child and the number of decayed teeth present before the start of the treatment significantly correlated with the children in the incomplete treatment category (P < 0.05). Therefore, a worthy dental care was provided in a holistic approach to the children attending College of Dental Medicine training clinics. Age of the child and the number of decayed teeth were the factors affecting dental rehabilitation in children aged 3-12 years.

The objectives of this study were to (1) examine the relationships between Emotional Thinking Scale (ETS) scores and demographic variables such as income, years worked as a pharmacist, and hours worked per week and (2) determine the distribution of ETS scores among this sample of pharmacists. These objectives are significant to explore because they may provide important data regarding effective and ineffective pharmacist work-related behaviors that affect career and life success. A convenience sample of practicing pharmacists was selected. Participants completed the 8-item ETS and a demographic survey. The ETS predicts how an individual's thoughts might influence his or her emotions and behaviors. Researchers analyzed participant's ETS scores with his or her demographic responses. Data were analyzed using SPSS statistical software. One hundred twenty-five pharmacists completed the survey. Twenty-one percent of the sample scored between slightly high and very extremely high on the ETS. "often being incapacitated by strong feelings" correlated negatively with annual income r = -.309 (P = .008); "relying on feelings to deal with complex situations" correlated negatively with annual income r = -.253 (P = .026), with the "number of years practicing pharmacy" r = -.317 (P = .007), and "number of hours worked each week" r = -.317 (P = .007); and "focusing on details thus losing the big picture" was correlated negatively with annual income r = .215 (P = .05). These findings are consistent with the previous ETS research. The variables of interest in this study were negatively but significantly related. Emotional thinking scores decreased with pharmacy practice experience and may be counterproductive for career goals. Entry-level pharmacy education and continuing education programs may help develop self-awareness to this issue. © The Author(s) 2014.

Acne vulgaris is known to impair many aspects of quality of life. However, the correlation of this impairment with clinical severity remains equivocal despite various school, community and hospital-based studies. A hospital-based study was undertaken to measure the impairment of quality of life of patients of acne vulgaris and correlate it with the severity of lesions. This was a cross-sectional, questionnaire-based study in a cohort of 100 patients of acne vulgaris attending the outpatient department of our referral hospital. A physician measured the severity of lesions using the global acne grading system, and patients assessed quality of life by completing a questionnaire (Cardiff acne disability index). A correlation of these two was done; some additional correlations were brought out through demographic data collected from the patients. There was no correlation between the severity of acne vulgaris and an impaired quality of life. Patients who consumed alcohol and/or smoked cigarettes were found to have an impaired quality of life. While the severity of acne progressively lessened in older patients, the impact on quality of life increased. The sample size was small and there was a lack of guaranteed reliability on the self-reported quality of life. The severity of acne vulgaris does not correlate with impairment in quality of life.

The objective of this study is to evaluate the strength of content validity within the facial dysfunction domain of the Penn Acoustic Neuroma Quality-of-Life (PANQOL) Scale and to compare how it correlates with a facial dysfunction-specific QOL instrument (Facial Clinimetric Evaluation, FaCE). The study design is online questionnaire survey. Members of the British Acoustic Neuroma Association received both PANQOL questionnaires and the FaCE scale. 158 respondents with self-identified facial paralysis or dysfunction had completed PANQOL and FaCE data sets for analysis. The mean composite PANQOL score was 53.5 (range 19.2-93.5), whilst the mean total FaCE score was 50.9 (range 10-95). The total scores of the PANQOL and FaCE correlated moderate (r = 0.48). Strong correlation (r = 0.63) was observed between the PANQOL's facial dysfunction domain and the FaCE total score. Of all the FaCE domains, social function was strongly correlated with the PANQOL facial dysfunction domain (r = 0.66), whilst there was very weak-to-moderate correlation (range 0.01-0.43) to the other FaCE domains. The current study has demonstrated a strong correlation between the facial dysfunction domains of PANQOL with a facial paralysis-specific QOL instrument.

Of the five personality dimensions described by the Big Five Personality Model (Costa and McCrae 1992), Extraversion and Agreeableness are the traits most commonly associated with a pro-social orientation. In this study we tested whether a pro-social orientation, as expressed in terms of Extraversion and Agreeableness, is associated with a specific grey matter phenotype. Fifty-two healthy participants underwent magnetic resonance imaging (MRI) and completed the NEO-Five Factor Inventory (NEO-FFI), a self-report measure of the Big Five personality traits. Voxel-based morphometry (VBM) was used to investigate the correlation between brain structure and the personality traits of Agreeableness and Extraversion. We found that Extraversion was negatively correlated with grey matter density in the middle frontal and orbitofrontal gyri while Agreeableness was negatively correlated with grey matter density in the inferior parietal, middle occipital and posterior cingulate gyri. No positive correlations were found. These results suggest that pro-social personality traits seem to be associated with decreases in grey matter density in more frontal regions for Extraversion, and more posterior regions for Agreeableness.

We addressed the hypothesis that perceptual priming and explicit memory have distinct neural correlates at encoding. Event-related potentials (ERPs) were recorded while participants studied visually presented words at deep versus shallow levels of processing (LOPs). The ERPs were sorted by whether or not participants later used studied words as completions to three-letter word stems in an intentional memory test, and by whether or not they indicated that these completions were remembered from the study list. Study trials from which words were later used and not remembered (primed trials) and study trials from which words were later used and remembered (remembered trials) were compared to study trials from which words were later not used (forgotten trials), in order to measure the ERP difference associated with later memory (DM effect). Primed trials involved an early (200-450 msec) centroparietal negative-going DM effect. Remembered trials involved a late (900-1200 msec) right frontal, positive-going DM effect regardless of LOP, as well as an earlier (600-800 msec) central, positive-going DM effect during shallow study processing only. All three DM effects differed topographically, and, in terms of their onset or duration, from the extended (600-1200 msec) fronto-central, positive-going shift for deep compared with shallow study processing. The results provide the first clear evidence that perceptual priming and explicit memory have distinct neural correlates at encoding, consistent with Tulving and Schacter's (1990) distinction between brain systems concerned with perceptual representation versus semantic and episodic memory. They also shed additional light on encoding processes associated with later explicit memory, by suggesting that brain processes influenced by LOP set the stage for other, at least partially separable, brain processes that are more directly related to encoding success.

Objective: To investigate the views and assess motivation, attitudes of pharmacists in Lebanon towards mandatory continuous education (CE), its transition to Continuous Professional Development (CPD), and identify barriers to participation in CPD. Methods: A cross-sectional observational study, conducted between February and May 2017, enrolled 591 pharmacists. The questionnaire used in this study was developed after an extensive literature review and based on previous similar studies in different countries. Results: Half of the pharmacists who completed the questionnaire agreed that all the factors that were mentioned in the questionnaire motivated completing CPD, whereas 55.4% felt confident that CPD meets their needs. 78.4% felt confident in their abilities to assess what they have learned. 71.6% felt confident in their abilities to assess what additional CPD activity may be necessary. The majority of the pharmacists agreed that accessibility of group learning activities (location/distance) (69.6%), job restrictions (76.3%) and lack of time (80.6%) were the most essential barriers against participation in CPD. Motivation was significantly and positively correlated with attitude (r= 0.718), but negatively correlated with barriers (r= -0.243). Attitude was significantly and negatively correlated with barriers (r= -0.120). Conclusion: Our findings contribute to informing the forward pathway for the profession. Attitude and motivation to CPD were positive in this study. Accessibility of group learning activities due to distance and location, job restrictions and lack of time were the major barriers to participation in CPD. Potential solutions can be sought to address these issues. PMID:29619137

Most of the research into suicide and self-harm has been conducted in the United States and Europe, yet the volume of research does not reflect the distribution of suicide globally, with Asia accounting for up to 60% of all suicides. The present study systematically reviews the literature to assess the prevalence and correlates of suicidal acts in Malaysia in Southeast Asia. Five relevant databases were searched from inception up to February 2014, and a narrative synthesis of the results from the included studies was performed. Studies were eligible for inclusion if they were correlational survey research and archival/observational research describing self-harm and suicide. Outcomes included completed suicides and self-harm including suicide attempts and self-poisoning, suicide plans and suicidal ideation. In total, 39 studies met the inclusion criteria. The principal findings were that the prevalence of suicide in Malaysia is approximately 6-8 per 100,000 population per year and that there is an excess of suicide among men, people younger than 40 years and the Indian minority group. The past-month prevalence rates of suicidal ideation, plans and attempts are 1.7, 0.9% and 0.5%, respectively, whereas the past-year prevalence rates of suicidal ideation range between 6% and 8%. The present research marks a first step towards understanding the prevalence and correlates of suicide and self-harm in Malaysia. However, the heterogeneity of the included studies was high. Further research into the antecedents, consequences and interventions for suicide and self-harm in the Malaysian context is required. Copyright © 2015 Elsevier Inc. All rights reserved.

A protected block curriculum (PBC) with postcurriculum examinations for all surgical residents has been provided to assure coverage of core curricular topics. Biannual assessment of resident competency will soon be required by the Next Accreditation System. To identify opportunities for early medical knowledge assessment and interventions, we examined whether performance in postcurriculum multiple-choice examinations (PCEs) is predictive of performance in the American Board of Surgery In-Training Examination (ABSITE) and clinical service competency assessments. Retrospective single-institutional education research study. Academic general surgery residency program. A total of 49 surgical residents. Data for PGY1 and PGY2 residents participating in the 2008 to 2012 PBC are included. Each resident completed 6 PCEs during each year. The results of 6 examinations were correlated to percentage-correct ABSITE scores and clinical assessments based on the 6 Accreditation Council for Graduate Medical Education core competencies. Individual ABSITE performance was compared between PGY1 and PGY2. Statistical analysis included multivariate linear regression and bivariate Pearson correlations. A total of 49 residents completed the PGY1 PBC and 36 completed the PGY2 curriculum. Linear regression analysis of percentage-correct ABSITE and PCE scores demonstrated a statistically significant correlation between the PGY1 PCE 1 score and the subsequent PGY1 ABSITE score (p = 0.037, β = 0.299). Similarly, the PGY2 PCE 1 score predicted performance in the PGY2 ABSITE (p = 0.015, β = 0.383). The ABSITE scores correlated between PGY1 and PGY2 with statistical significance, r = 0.675, p = 0.001. Performance on the 6 Accreditation Council for Graduate Medical Education core competencies correlated between PGY1 and PGY2, r = 0.729, p = 0.001, but did not correlate with PCE scores during either years. Within a mature PBC, early performance in a PGY1 and PGY2 PCE is predictive of performance in the respective ABSITE. This information can be used for formative assessment and early remediation of residents who are predicted to be at risk for poor performance in the ABSITE.

Employee psychological capital (PsyCap), perceptions of organizational virtue (OV), and work happiness have been shown to be associated within and over time. This study examines selective exposure and confirmation bias as potential processes underlying PsyCap, OV, and work happiness associations. As part of a quasi-experimental study design, school staff (N = 69) completed surveys at three time points. After the first assessment, some staff (n = 51) completed a positive psychology training intervention. Results of descriptive statistics, correlation, and regression analyses on the intervention group provide some support for selective exposure and confirmation bias as explanatory mechanisms. In focusing on the processes through which employee attitudes may influence work happiness this study advances theoretical understanding, specifically of selective exposure and confirmation bias in a field study context.

To evaluate the correlation of the flow patterns of the four pulmonary veins as assessed by transesophageal echocardiography and the influence of significant mitral regurgitation on this correlation. Eighty-eight patients with normal sinus rhythm and variable underlying cardiovascular diseases underwent transthoracic and transesophageal echocardiographic studies. Doppler flow of the four pulmonary veins could not be adequately interpreted in 19 patients (22%). The left atrial dimension of these patients was significantly larger than that of the patients with complete study of the flow in the four pulmonary veins (49 +/- 6 vs. 43 +/- 7 mm; p < 0.05). Of the 69 patients with complete evaluation of the four pulmonary veins, 48 patients without significant mitral regurgitation were analyzed as group A, and the remaining 21 patients as group B. The peak systolic and diastolic forward flow velocities of the four pulmonary veins were measured and the ratio of peak systolic (S) to diastolic (D) flow velocity was calculated. Group A had a significantly larger S/D ratio in all four pulmonary veins than group B (p < 0.05 in each pulmonary vein measurement). There was good correlation of the flow pattern represented as S/D ratio between left upper and lower pulmonary veins (r = 0.90) and between right upper and lower pulmonary veins (r = 0.89) in group A. The correlation of the flow pattern among the four pulmonary veins deteriorated in group B. Pulmonary veins on the same side share rather similar flow patterns in comparison with pulmonary veins on the opposite sides. The correlation of flow patterns among the four pulmonary veins is good in subjects without significant mitral regurgitation, but it worsens in patients with significant mitral regurgitation. Therefore, cautious interpretation of flow patterns of the four pulmonary veins in patients with significant regurgitation is indicated for grading the severity of mitral regurgitation.

Criminal thinking styles and emotional intelligence in Egyptian offenders.

Megreya, Ahmed M

2013-02-01

The Psychological Inventory of Criminal Thinking Styles (PICTS) has been applied extensively to the study of criminal behaviour and cognition. Increasingly growing evidence indicates that criminal thinking styles vary considerably among individuals, and these individual variations appear to be crucial for a full understanding of criminal behaviour. This study aimed to examine individual differences in criminal thinking as a function of emotional intelligence. A group of 56 Egyptian male prisoners completed the PICTS and Bar-On Emotional Quotient Inventory (EQ-i). The correlations between these assessments were examined using a series of Pearson correlations coefficients, with Bonferroni correction. General criminal thinking, reactive criminal thinking and five criminal thinking styles (mollification, cutoff, power orientation, cognitive indolence and discontinuity) negatively correlated with emotional intelligence. On the other hand, proactive criminal thinking and three criminal thinking styles (entitlement, superoptimism and sentimentality) did not associate with emotional intelligence.

Adolescent Defense Style as Correlate of Problem Behavior.

PubMed

Huemer, Julia; Shaw, Richard J; Prunas, Antonio; Hall, Rebecca; Gross, James; Steiner, Hans

2015-09-01

Adolescent problem behaviors are often the visible results of intrapsychic distress. Defensive reactions are the unconscious means of managing intrapsychic distress. This cross-sectional study examines the strength of defensive style as measured by self-report on the Response Evaluation Measure (REM-71) relative to age, sex, and SES, as a correlate of internalizing and externalizing problem behaviors, as assessed by the Youth Self Report (YSR). A sample of 1,487 students from two suburban high schools completed self-report measures of defense style, self-esteem, and internalizing and externalizing problem behaviors. Demographic variables (age, sex, and SES) were included as covariates. Mature and immature defense style correlated as expected with problem behaviors. Demographic variables contributed minimally to the variance in the outcome variable. Defense style, as assessed by the REM-71, is a significant correlate of clinically elevated internalizing and externalizing problem behaviors in youth as in adults. This study adds to the convergent validity of the REM-71.

Measures of health sciences journal use: a comparison of vendor, link-resolver, and local citation statistics.

Libraries require efficient and reliable methods to assess journal use. Vendors provide complete counts of articles retrieved from their platforms. However, if a journal is available on multiple platforms, several sets of statistics must be merged. Link-resolver reports merge data from all platforms into one report but only record partial use because users can access library subscriptions from other paths. Citation data are limited to publication use. Vendor, link-resolver, and local citation data were examined to determine correlation. Because link-resolver statistics are easy to obtain, the study library especially wanted to know if they correlate highly with the other measures. Vendor, link-resolver, and local citation statistics for the study institution were gathered for health sciences journals. Spearman rank-order correlation coefficients were calculated. There was a high positive correlation between all three data sets, with vendor data commonly showing the highest use. However, a small percentage of titles showed anomalous results. Link-resolver data correlate well with vendor and citation data, but due to anomalies, low link-resolver data would best be used to suggest titles for further evaluation using vendor data. Citation data may not be needed as it correlates highly with other measures.

Combining individual participant and aggregated data in a meta-analysis with correlational studies.

This paper presents methods for combining individual participant data (IPD) with aggregated study level data (AD) in a meta-analysis of correlational studies. Although medical researchers have employed IPD in a wide range of studies, only a single example exists in the social sciences. New policies at the National Science Foundation requiring grantees to submit data archiving plans may increase social scientists' access to individual level data that could be combined with traditional meta-analysis. The methods presented here extend prior work on IPD to meta-analyses using correlational studies. The examples presented illustrate the synthesis of publicly available national datasets in education with aggregated study data from a meta-analysis examining the correlation of socioeconomic status measures and academic achievement. The major benefit of the inclusion of the individual level is that both within-study and between-study interactions among moderators of effect size can be estimated. Given the potential growth in data archives in the social sciences, we should see a corresponding increase in the ability to synthesize IPD and AD in a single meta-analysis, leading to a more complete understanding of how within-study and between-study moderators relate to effect size.

Research has shown inconsistencies in results and difficulties in conceptualization of assessment of socioeconomic status (SES) among adolescents. The aim of this study was thus to test the validity of self-reported information on SES in two age-groups (11-13 and 14-16 years old) in an adolescent population and to evaluate its relationship to self-reported health related quality of life (HRQOL). Different measures of SES commonly used in research in relation to HRQOL were tested in this study; parent's occupations status, family material affluence status (FAS) and perceived SES. A cross-sectional study, with a sample of 948 respondents (n = 467, 11-13 years old and n = 481, 14-16 years old) completed questionnaires about SES and HRQOL. The adolescents' completion rates were used, with chi2-test, to investigate differences between gender and age-group. Correlation was used for convergent validity and ANOVA for concurrent validity. We found a low completion rate for both fathers' (41.7 %) and mothers' (37.5 %) occupation status, and a difference in completion rate between gender and age-groups. FAS had the highest completion rate (100 %) compared to parent's occupations status and perceived SES. The convergent validity between the SES-indicators was weak (Spearman correlation coefficient below 0.3), suggesting that the indicators measured different dimensions of SES. Both FAS and perceived SES showed a gradient in mean HRQOL between low and high SES in relation to HRQOL, this was significant only for perceived SES (p < 0.01, both age-groups). This study indicates the need for considering different approaches to measures of SES among adolescences and when evaluating SES in relation to HRQOL. Further research is needed to investigate sustainable ways to measure SES, delineating the relevance of tangible measures of education, occupation and income in relation to the perceived socioeconomic status in comparison with others in immediate social networks and in society at large.

Some life events appear heritable due to the genetic influence on related behaviours. Shared genetic influence between negative behaviours and negative life events has previously been established. This study investigated whether subjective wellbeing and positive life events were genetically associated. Participants in the Twins Early Development Study (aged 16.32 ± .68 years) completed subjective wellbeing and life events assessments via two separate studies (overlapping N for wellbeing and life events measures ranged from 3527 to 9350). We conducted bivariate twin models between both positive and negative life events with subjective wellbeing and related positive psychological traits including subjective happiness, life satisfaction, optimism, hopefulness and gratitude measured at 16 years. Results suggested that the heritability of life events can partially be explained by shared genetic influences with the wellbeing indicators. Wellbeing traits were positively genetically correlated with positive life events and negatively correlated with negative life events (except curiosity where there was no correlation). Those positive traits that drive behaviour (grit and ambition) showed the highest genetic correlation with life events, whereas the reflective trait gratitude was less correlated. This suggests that gene-environment correlations might explain the observed genetic association between life events and wellbeing. Inheriting propensity for positive traits might cause you to seek environments that lead to positive life events and avoid environments which make negative life events more likely.

A second-order closure analysis of turbulent diffusion flames. [combustion physics

A complete second-order closure computer program for the investigation of compressible, turbulent, reacting shear layers was developed. The equations for the means and the second order correlations were derived from the time-averaged Navier-Stokes equations and contain third order and higher order correlations, which have to be modeled in terms of the lower-order correlations to close the system of equations. In addition to fluid mechanical turbulence models and parameters used in previous studies of a variety of incompressible and compressible shear flows, a number of additional scalar correlations were modeled for chemically reacting flows, and a typical eddy model developed for the joint probability density function for all the scalars. The program which is capable of handling multi-species, multistep chemical reactions, was used to calculate nonreacting and reacting flows in a hydrogen-air diffusion flame.

This study examined the correlation of physical activity with neurological impairment and disability in persons with multiple sclerosis (MS). Eighty individuals with MS wore an accelerometer for 7 days and completed the Symptom Inventory (SI), Performance Scales (PS), and Expanded Disability Status Scale. There were large negative correlations between the accelerometer and SI (r = -0.56; rho = -0.58) and Expanded Disability Status Scale (r = -0.60; rho = -0.69) and a moderate negative correlation between the accelerometer and PS (r = -0.39; rho = -0.48) indicating that physical activity was associated with reduced neurological impairment and disability. Such findings provide a preliminary basis for using an accelerometer and the SI and PS as outcome measures in large-scale prospective and experimental examinations of the effect of physical activity behavior on disability and dependence in MS.

Knowledge, Attitude and Advice-Giving Behaviour of Community Pharmacists Regarding Topical Corticosteroids

PubMed Central

Lau, Wing Man

2017-01-01

This study examines the relationship between community pharmacists’ knowledge, attitudes to information provision and self-reported counselling behaviours in relation to topical corticosteroids and adjunct therapy in atopic eczema. A mixed-methods approach was used whereby data from interviews with community pharmacists were used to design a structured questionnaire that a larger sample of community pharmacists completed anonymously. The questionnaire was completed and returned by 105 pharmacists (36% response rate). Pharmacists showed gaps in their knowledge on the use of topical corticosteroids in atopic eczema but had good understanding on the use of emollients. There was a significant correlation between pharmacists’ attitudes to information provision and their self-reported counselling behaviour for most themes except in relation to corticosteroid safety where less advice was given. Improving attitudes to information provision should correlate with increased counselling behaviour. However, for the theme of corticosteroid safety, further studies are needed to examine why in practice pharmacists are not providing patient counselling on this topic even though most agreed this is a topic patients should know about.

This study examined the nature and correlates of hoarding among youth with autism spectrum disorders (ASD). Forty children with ASD and a comorbid anxiety disorder were administered a battery of clinician-administered measures assessing presence of psychiatric disorders and anxiety severity. Parents completed questionnaires related to child hoarding behaviors, social responsiveness, internalizing and externalizing behaviors, and functional impairment. We examined the impact of hoarding behaviors on treatment response in a subsample of twenty-six youth who completed a course of personalized cognitive-behavioral therapy targeting anxiety symptoms. Hoarding symptoms were common and occurred in a clinically significant manner in approximately 25 % of cases. Overall hoarding severity was associated with increased internalizing and anxiety/depressive symptoms, externalizing behavior, and attention problems. Discarding items was associated with internalizing and anxious/depressive symptoms, but acquisition was not. Hoarding decreased following cognitive-behavioral therapy but did not differ between treatment responders and non-responders. These data are among the first to examine hoarding among youth with ASD; implications of study findings and future directions are highlighted.

Relationships between magical thinking, obsessive-compulsiveness and other forms of anxiety in a sample of non-clinical children.

Simonds, Laura M; Demetre, James D; Read, Cristina

2009-06-01

Despite the obvious phenomenological similarities between magical thinking and obsessive-compulsiveness, the relationship between them has been the subject of few empirical investigations in samples of children. The present study aimed to examine the relationship between a general epistemic stance towards magical causation and tendencies towards obsessive-compulsiveness in a non-clinical sample of schoolchildren. One-hundred and two children, aged between 5 and 10 years (48 boys and 54 girls), completed questionnaire measures designed to assess magical thinking, obsessive-compulsiveness, and other forms of anxiety. School teachers completed a measure of strengths and difficulties for each child. General belief in magical causation was correlated with all types of anxiety, not just obsessive-compulsiveness, with significant correlations shown for boys in the sample, but not girls. General belief in magical causation contributed little to the prediction of obsessive-compulsiveness beyond general anxiety. In this study, a general epistemic stance towards magical causation did not differentiate obsessive-compulsiveness from other anxiety dimensions. The findings are considered in the context of developmental theories of magical and scientific causal reasoning.

This study aims to assess the level of self-esteem of newly delivered mothers who had caesarean section (CS) and evaluate the sociodemographic and obstetrics correlates of low self-esteem in them. Newly delivered mothers who had CS (n = 109) and who had spontaneous vaginal delivery (SVD) (n = 97) completed questionnaires on sociodemographic and obstetrics variables within 1 week of delivery. They also completed the Rosenberg self-esteem scale. RESULTS. Women with CS had statistically significant lower scores on the self-esteem scale than women with SVD (p = 0.006). Thirty (27.5%) of the CS group were classified as having low self-esteem compared with 11 (11.3%) of the SVD group (p = 004). The correlates of low self-esteem in the CS group included polygamy (odd ratio (OR) 4.99, 95% confidence interval (95% CI) 1.62-15.33) and emergency CS (OR 4.66, 95% CI 1.55-16.75). CS in South-Western Nigerian women is associated with lowered self-esteem in the mothers.

An age-associated decline in testosterone (T) levels and an increase in proinflammatory cytokines contribute to chronic diseases in older men. Whether and how these changes are related is unclear. We hypothesized that T and inflammatory markers are negatively correlated in older men. This was a cross-sectional study. A population-based sample of older men was studied. After excluding participants taking glucocorticoids or antibiotics or those with recent hospitalization, 467 men, aged 65 yr or older, had complete determinations of total T, bioavailable T, SHBG, albumin, IL-6, soluble IL-6 receptor (sIL-6r), TNF-alpha, IL-1beta, and C-reactive protein. After adjusting for potential confounders, sIL-6r was significantly and inversely correlated with total T (r = -0.20; P < 0.001) and bioavailable T (r = -0.12; P < 0.05). T was not correlated with any other inflammatory marker. These preliminary findings suggest an inverse relationship between T and sIL-6r. Longitudinal studies are needed to establish the causality of this association.

2015-05-15

Quality of life in Friedreich ataxia (FRDA) has been explored using various generic health status measurement tools, most commonly the Short Form Health Survey Version 2 (SF-36v2). The tool did not address many specific issues related to disease impact in people with FRDA. The Friedreich Ataxia Impact Scale (FAIS) was developed to examine clinically relevant areas in FRDA. The aims of the current study were to assess the relationship between the FAIS and clinical characteristics of FRDA, as well as to determine the responsiveness of the FAIS to change over one and two years. One hundred and four individuals with FRDA, homozygous for the GAA expansion in intron 1 of FXN, completed the FAIS at baseline. Seventy individuals completed the FAIS again 12 months later and 49 completed the FAIS at 24 months. Clinical parameters and neurologic scales (Friedreich Ataxia Rating Scale (FARS)) were also recorded. The total FARS score, onset age and disease duration correlated significantly with FAIS subscales measuring symptoms and physical functioning. The physical and mental summary measures of the SF-36 V2 also correlated well with the FAIS subscales. Speech was the only subscale that demonstrated significant change over one and two years. The FAIS provides valuable insight into the perspective of individuals with FRDA on their health status, and is an important measure of morbidity. It has, however, limited responsiveness to change and its use in intervention studies is questionable. Copyright © 2015 Elsevier B.V. All rights reserved.

Oral malodor and removable complete dentures in the elderly.

2008-06-01

The objectives of this study were to assess oral malodor in patients with removable complete dentures and analyze its association with age, sex, subjective oral dryness, burning mouth, tongue coating, and overnight denture wear in elderly subjects. The study comprised 105 complete denture wearers (56 male, 49 female) between the ages of 50 and 78 from the province of Kirikkale in the Central Anatolia Region of Turkey. Oral malodor was assessed using a portable sulfide monitor. Participants were given a self-administered, structured questionnaire. Baseline and final volatile sulfur compound (VSC) levels and tongue-coating scores (TCS) were measured. Analysis included frequency, cross-tabulations, ANOVA, and independent sample and paired t tests. Odds ratios of VSC-related factors were also calculated. A P value less than .05 was considered statistically significant. There was no significant correlation found between age, gender, smoking, existence of a medical condition, or regular use of medication and VSC levels in mouth air (P > .05). However, educational level (P < .05), oral dryness (P < .05), burning mouth (P < .05), overnight denture wear (P < .01), and TCS (P < .001) were found to be significantly correlated with VSC levels. Significant differences were also found between baseline and final measurements of both VSC levels and TCS (P < .01). This study found the accumulation of bacterial plaque on the tongue, oral dryness, burning mouth, overnight denture wear, and lower educational levels to be significantly related to oral malodor. Following tongue care maintenance and overnight removal of dentures, patients' oral malodor levels decreased significantly.

2018-01-01

Many US medical schools have added a scholarly or research requirement as a potential intervention to increase the number of medical students choosing to become academic physicians and physician scientists. We designed a retrospective qualitative survey study to evaluate the impact of medical school research at the University of Alabama at Birmingham (UAB) on career choices. A survey tool was developed consisting of 74 possible questions with built-in skip patterns to customize the survey to each participant. The survey was administered using the web-based program Qualtrics to UAB School of Medicine alumni graduating between 2000 and 2014. Alumni were contacted 3 times at 2-week intervals during the year 2015, resulting in 168 completed surveys (11.5% response rate). MD/PhD graduates were excluded from the study. Most respondents completed elective research, typically for reasons relating to career advancement. 24 per cent said medical school research increased their desire for research involvement in the future, a response that positively correlated with mentorship level and publication success. Although completion of medical school research was positively correlated with current research involvement, the strongest predictor for a physician scientist career was pre-existing passion for research (p=0.008). In contrast, students motivated primarily by curricular requirement were less likely to pursue additional research opportunities. Positive medical school research experiences were associated with increased postgraduate research in our study. However, we also identified a strong relationship between current research activity and passion for research, which may predate medical school. PMID:28270407

Method Event-related potentials were recorded in 16 comparison subjects and 17 schizotypal individuals (who met full DSM-III-R criteria) to sentences presented both visually and aurally; half of the sentences ended with an expected word completion (congruent condition), and the other half ended with an unexpected word completion (incongruent condition). Results In the congruent condition, the N400 amplitude was more negative in individuals with schizotypal personality disorder than in comparison subjects in both the visual and auditory modalities. In addition, in the visual modality, the N400 latency was prolonged in the individuals with schizotypal personality disorder. Conclusions The N400 was found to be abnormal in the individuals with schizotypal personality disorder relative to comparison subjects. The abnormality was similar to the abnormality the authors’ laboratory reported earlier in schizophrenic subjects, in which the N400 amplitude was found to be more negative in both congruent and incongruent sentence completions. The N400 abnormality is consistent with the inefficient use of context. PMID:10401451

We investigate the performance of multiconfiguration pair-density functional theory (MC-PDFT) and complete active space second-order perturbation theory for computing the bond dissociation energies of the diatomic molecules FeC, NiC, FeS, NiS, FeSe, and NiSe, for which accurate experimental data have become recently available [Matthew, D. J.; Tieu, E.; Morse, M. D. J. Chem. Phys. 2017, 146, 144310-144320]. We use three correlated participating orbital (CPO) schemes (nominal, moderate, and extended) to define the active spaces, and we consider both the complete active space (CAS) and the separated-pair (SP) schemes to specify the configurations included for a given active space. We found that the moderate SP-PDFT scheme with the tPBE on-top density functional has the smallest mean unsigned error (MUE) of the methods considered. This level of theory provides a balanced treatment of the static and dynamic correlation energies for the studied systems. This is encouraging because the method is low in cost even for much more complicated systems.

High-structure courses or flipped courses require students to obtain course content before class so that class time can be used for active-learning exercises. While textbooks are used ubiquitously in college biology courses for content dissemination, studies have shown that students frequently do not read their textbooks. To address this issue, we created preclass reading guides that provided students with a way to actively engage with the required reading for each day of class. To determine whether reading guide completion before class is associated with increased performance, we surveyed students about their use of reading guides in two sections of a large-enrollment (400+ students) introductory biology course and used multiple linear regression models to identify significant correlations. The results indicated that greater than 80% of students completed the reading guides before class and that full completion of the reading guides before class was significantly positively correlated with exam performance. Reading guides in most cases were used similarly between different student groups (based on gender, ethnicity, and aptitude). These results suggest that optional preclass reading guides may help students stay on track to acquire course content in introductory biology and thus result in improved exam performance.

Background: There are significant post-surgical reductions in health-related quality of life (HRQOL) in prostate cancer (PCa) patients undergoing radical prostatectomy (RP). Physical activity (PA) interventions have improved treatment outcomes for PCa patients undergoing radiation and hormone therapy, but PA effects have not previously been examined in the RP setting. This study examined the relationship between preoperative PA levels and postoperative HRQOL outcomes in PCa patients treated with RP. Methods: Sixty patients were interviewed regarding lifetime PA and completed preoperative (2 weeks prior to surgery) and postoperative (4 weeks after surgery) HRQOL questionnaires. Aerobic fitness testing was conducted on a subsample of 22 patients. Results: Higher levels of total past-year PA and occupational PA significantly correlated with lesser HRQOL declines from presurgery to 4 weeks post-surgery (Beta = −0.364, p = 0.037 and Beta = −0.243, p = 0.089, respectively) in models adjusted for age, postoperative questionnaire completion date, Gleason score and education. Past-year occupational PA was highly positively correlated with past-year total PA (r = 0.785, p < 0.001). Lifetime total PA was correlated with estimated VO2 max (r = 0.486, p = 0.026) in the 22 patients who were aerobically tested. Lifetime and past-year PA volumes were not correlated with waist circumference or body mass index. Interpretation: Declines in HRQOL after RP may be reduced in patients with higher preoperative levels of self-reported PA. These findings require further study with larger samples to confirm results. If confirmed, findings suggest exercise preoperatively may improve HRQOL outcomes after RP. PMID:20514281

Cognitive assessments are valuable tools in assessing neurological conditions. They are critical in measuring deficits in cognitive function in an array of neurological disorders and during the ageing process. Automation of cognitive assessments is one way to address the increasing burden on medical resources for an ever increasing ageing population. This study investigated the suitability of using automated Interactive Voice Response (IVR) technology to deliver a suite of cognitive assessments to older adults using speech as the input modality. Several clinically valid and gold-standard cognitive assessments were selected for implementation in the IVR application. The IVR application was designed using human centred design principles to ensure the experience was as user friendly as possible. Sixty one participants completed two IVR assessments and one face to face (FF) assessment with a neuropsychologist. Completion rates for individual tests were inspected to identify those tests that are most suitable for administration via IVR technology. Interclass correlations were calculated to assess the reliability of the automated administration of the cognitive assessments across delivery modes. While all participants successfully completed all automated assessments, variability in the completion rates for different cognitive tests was observed. Statistical analysis found significant interclass correlations for certain cognitive tests between the different modes of administration. Analysis also suggests that an initial FF assessment reduces the variability in cognitive test scores when introducing automation into such an assessment. [corrected] This study has demonstrated the functional and cognitive reliability of administering specific cognitive tests using an automated, speech driven application. This study has defined the characteristics of existing cognitive tests that are suitable for such an automated delivery system and also informs on the limitations of other cognitive tests for this modality. This study presents recommendations for developing future large scale cognitive assessments.

This study is aimed at identifying the relationships between medical school students' academic burnout, empathy, and calling, and determining whether their calling has a mediating effect on the relationship between academic burnout and empathy. A mixed method study was conducted. One hundred twenty-seven medical students completed a survey. Scales measuring academic burnout, medical students' empathy, and calling were utilized. For statistical analysis, correlation analysis, descriptive statistics analysis, and hierarchical multiple regression analyses were conducted. For qualitative approach, eight medical students participated in a focus group interview. The study found that empathy has a statistically significant, negative correlation with academic burnout, while having a significant, positive correlation with calling. Sense of calling proved to be an effective mediator of the relationship between academic burnout and empathy. This result demonstrates that calling is a key variable that mediates the relationship between medical students' academic burnout and empathy. As such, this study provides baseline data for an education that could improve medical students' empathy skills.

Our research goal was to complete a retrospective chart review to determine if there is a correlation between the level of diabetic retinopathy and diabetic neurosensory hearing loss. A retrospective analysis of 175 Department of Veterans Affairs Computerized Patient Record System charts was completed at the VA Portland Health Care System. Subjects were classified by degree of diabetic retinopathy as follows: no diabetic retinopathy (n = 80), mild nonproliferative diabetic retinopathy (n = 51), moderate nonproliferative diabetic retinopathy (n = 25), and combined severe nonproliferative diabetic retinopathy and proliferative diabetic retinopathy (PDR) (n = 17). Degree of sensorineural hearing was collected for each ear. Additionally, measures of diabetic control, including hemoglobin A1C, and creatinine, were recorded. After controlling for diabetic control, as measured by HbA1C and creatinine, level of diabetic retinopathy was significantly associated with hearing loss severity in both ears (right ear, P = .018 and left ear, P = .007). When adjusted to include diabetes control, the severity of diabetic retinopathy showed a correlation with degree of hearing loss at most levels. Because of this association, recommendation for hearing evaluations may be considered for those with mild, moderate, or severe nonproliferative or proliferative diabetic retinopathy.

This study examined the frequency and sociodemographic and clinical correlates of suicidal ideation in a sample of children and adolescents with obsessive-compulsive disorder (OCD). Fifty-four youth with OCD and their parent(s) were administered the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime, Children's Yale-Brown Obsessive Compulsive Scale, and Children's Depression Rating Scale-Revised. Children completed the Suicidal Ideation Questionnaire-Junior (SIQ-JR), Child Obsessive Compulsive Impact Scale-Child, and Multidimensional Anxiety Scale for Children; parents completed the Child Obsessive Compulsive Impact Scale-Parent, Swanson, Nolan, and Pelham-IV Parent Scale, and Young Mania Rating Scale-Parent Version. Seven youth endorsed clinically significant levels of suicidal ideation on the SIQ-JR. Suicidal ideation was significantly related to clinician-rated depressive symptoms, age, child-rated impairment and anxiety symptoms, and symmetry, sexuality/religiosity and miscellaneous symptom dimensions. There was no significant association between suicidal ideation and obsessive-compulsive symptom severity, comorbidity patterns, or several parent-rated indices (e.g., impairment, impulsivity). These results provide initial information regarding the frequency and correlates of suicidal ideation in treatment-seeking youth with OCD. Clinical implications are discussed, as well as directions for future research.

This cross-sectional study presents an initial psychometric evaluation of a two-dimensional (perceptual and evaluative) conceptualization and measure of disrupted body integrity (DBI)-illness-related disruption of the sense of the body as an integrated, smoothly functioning whole. Male and female head and neck cancer (HNC) outpatients (N = 98) completed a questionnaire package prior to outpatient visits. The Disrupted Body Integrity Scale (DBIS) was developed to measure the perceptual and evaluative facets of DBI. Self-report measures of disfigurement, stigma, depressive symptoms, and negative affect were also completed. Almost all DBIS subscales demonstrated good internal consistency. Results largely supported the DBIS's construct validity. The majority of subscales correlated within the predicted range of r's = .40-.70. Almost all DBIS constructs were positively linked with either depressive symptoms or disfigurement. None correlated with positive affect, and only two subscales, abnormal sensations (perceptual) and physical vulnerability (evaluative), correlated with negative affect. DBIS constructs showed little relation with stigma, once disfigurement effects were controlled for. Findings offer preliminary evidence for the DBIS and the relevance of DBI in HNC. Further evaluation of DBI in disease adaptation and the DBIS's factor structure is warranted.

During a cognitive stimulation session where elders with cognitive decline perform stimulation activities, such as solving puzzles, we observed that they require constant supervision and support from their caregivers, and caregivers must be able to monitor the stimulation activity of more than one patient at a time. In this paper, aiming at providing support for the caregiver, we developed a vision-based system using an Phase-SDF filter that generates a composite reference image which is correlated to a captured wooden-puzzle image. The output correlation value allows to automatically verify the progress on the puzzle solving task, and to assess its completeness and correctness.

Purpose To verify the correlation between the voice handicap and swallowing quality of life in individuals submitted to chemoradiotherapy for laryngeal cancer treatment. Methods Cross-sectional, observational and quantitative study. Fourteen male individuals diagnosed with laryngeal cancer were submitted to exclusive chemoradiotherapy treatment. The individuals completed the Voice Handicap Index (VHI) and the Swallowing Quality of Life (SWAL-QOL) questionnaires. Data were submitted to descriptive and inferential analysis using Spearman's Correlation Test to verify possible correlations among the scores of these instruments. Values of p ≤ 0.05 were considered statistically significant. Results No significant correlation was found between the total VHI and overall SWAL-QOL scores. However, there was significant correlation between the domain Functional of the VHI and the domains Fatigue and Social of the SWAL-QOL, between the domain Organic in the VHI and the SWAL-QOL domain Social, and total VHI score and SWAL-QOL domain Swallowing as a burden. Furthermore, chemoradiotherapy treatment had a greater impact on the voice than on the swallowing for the studied individuals. Conclusion The data showed a significant correlation between voice handicap and the impact of quality of life involving swallowing in individuals with laryngeal cancer submitted to chemoradiotherapy. This may affect individuals' emotional and social aspects, impacting their overall quality of life.

Purpose. Tender points in the neck are common in patients with temporomandibular disorders (TMD). However, the correlation among neck disability, jaw dysfunction, and muscle tenderness in subjects with TMD still needs further investigation. This study investigated the correlation among neck disability, jaw dysfunction, and muscle tenderness in subjects with and without chronic TMD. Participants. Forty females between 19 and 49 years old were included in this study. There were 20 healthy controls and 20 subjects who had chronic TMD and neck disability. Methods. Subjects completed the neck disability index and the limitations of daily functions in TMD questionnaires. Tenderness of the masticatory and cervical muscles was measured using an algometer. Results. The correlation between jaw disability and neck disability was significantly high (r = 0.915, P < 0.05). The correlation between level of muscle tenderness in the masticatory and cervical muscles with jaw dysfunction and neck disability showed fair to moderate correlations (r = 0.32–0.65). Conclusion. High levels of muscle tenderness in upper trapezius and temporalis muscles correlated with high levels of jaw and neck dysfunction. Moreover, high levels of neck disability correlated with high levels of jaw disability. These findings emphasize the importance of considering the neck and its structures when evaluating and treating patients with TMD. PMID:25883963

The aim of the current study was to investigate the psychosocial impact of dental aesthetics among patients who received anterior implant-supported prostheses. The current study is a cross-sectional evaluation involving 115 individuals who had gone through treatment at the dental clinics of general hospitals. Participants completed the Chinese version of the psychosocial impact of dental aesthetics questionnaire (PIDAQ) before implantation and six months after crown restoration. Basic demographic information was recorded. Six months after implant crown restoration, participants were asked to self-assess their own oral aesthetics compared to before implantation. A total of 106 patients completed the study. PIDAQ scores correlated significantly with the self-assessment of the degree of oral aesthetics. Six months after crown restoration, the two factors (social impact and aesthetic attitude) decreased and the dental self-confidence score increased significantly compared to pre-implantation scores. Gender and education level significantly affected PIDAQ. Anterior implant-supported prostheses significantly affected the patients' psychosocial perception. Implantation of missing anterior teeth can significantly improve patients' negative psychosocial impact of dental aesthetics. Gender and education level are correlated with the degree of improvement. The PIDAQ can be used in assessing the psychosocial effects of implantation in missing anterior teeth.

The purpose of this study was to assess the levels of dental fear, state anxiety, and physiological distress in children and their mothers during pediatric dental procedures and to investigate the associations between these variables. Forty children and their mothers who visited six pediatric dental clinics in Tokyo, Japan, participated in this study. Dental fear was assessed using the dental subscale of the Children's Fear Survey Schedule (CFSS-DS) and the Dental Fear Survey. Children completed the pre- and post-treatment State-Trait Anxiety Inventory for Children-State (STAIC-S), and mothers completed the State-Trait Anxiety Inventory-State (STAI-S). Pre- and post-treatment salivary alpha amylase (sAA) levels were measured to assess physiological distress. Paired t tests and Pearson's correlation coefficients were used for statistical analyses. State anxiety scores and sAA levels significantly differed between pre- and post-treatment in mothers (P=.007 and P<.02, respectively) but not in children. Pretreatment STAI-S scores in mothers were correlated with CFSS-DS scores in children (r=.348, P<.03), but pretreatment STAI-S and STAIC-S scores were not. Maternal anxiety before children's dental treatment was significantly associated with children's dental fear.

A common symptom for people with vestibulopathy is dizziness induced by dynamic visual input, known as visual vertigo (VV). The goal of this study is to present a novel method to assess VV, using a nine-item analog scale. The subjects rated the intensity of their dizziness on each item of the Visual Vertigo Analogue Scale (VVAS), which represented a daily situation typically inducing VV. The questionnaire was completed by participants with vestibulopathy (n=102) and by subjects receiving out-patient orthopaedic physiotherapy (n=102). The dizziness handicap inventory (DHI) was also completed by the vestibulopathic group. The Cronbach's Alpha index indicated the VVAS is internally consistent and reliable (Cronbach's Alpha=0.94). The study also found that the VVAS severity scores from vestibular and a non-vestibular population were significantly different (Wilcoxon-Mann Whitney test p < 0.0001). Spearman correlation analysis conducted between DHI and VVAS scores for the clients with vestibulopathy showed positive moderate correlations between the VVAS score and the total DHI score (r=0.67, p< 0.0001). This study showed that the VVAS scale may be useful in providing a quantitative evaluation scale of visual vertigo.

This article reviews published 16PF research on drug users. It also compares the 16PF scores of a new sample of nonusers with scores of matched groups of heavy, chronic users of cocaine, amphetamine, opiates, and barbiturates/sedative hypnotics, as well as combined groups of stimulant users, depressant users, and a combined group of users of all substances. No significant differences were found among drug user groups, but the profile of the nonuser group was distinctive. K-Means Cluster Analyses, as well as Cattell's Similarity and Pearson Product Moment Correlation Coefficients, were used to compare profiles of these new samples with the 19 groups described in an earlier meta-analysis of published 16PF studies. Data from the new samples did not cluster with data from other published research, although certain specific similarities appeared in more detailed correlational analyses. Methodological problems are discussed, and it is recommended that in future studies drug user groups be more carefully selected and defined, sample descriptions be more thorough and complete, complete profile information be routinely provided, and efforts be made to explore the utility of the Cattell CAQ in studies of drug users/misusers.

Our pilot study was conducted to test the reliability of the Caregiver's Feeding Styles Questionnaire (CFSQ) and the Family Nutrition and Physical Activity Assessment (FNPA) in a sample of Arab mothers. Twenty-five Arab mothers completed the CFSQ, FNPA, and the Participant Background Survey for the first administration. After 1-2 weeks, participants completed the CFSQ and the FNPA for the second administration. The two administrations of the surveys allowed for test/retest reliability of the CFSQ and the FNPA and to measure the internal consistency of the two surveys. Pearson's correlation between the first and second administrations or the 19-item scale (demandingness) and the 7-item scale (responsiveness) of the CFSQ were .95 and .86, respectively. As for the FNPA, Pearson's correlation was .80. The estimated reliabilities (Cronbach's alpha) of the CFSQ increased from .86 for the first administration to .93 for the second administration. However, the estimated reliabilities of the FNPA slightly increased from .58 for first administration to .59 for the second administration. In our pilot study of Arab mothers, the CFSQ and FNPA were shown to be promising in terms of reliability and content validity.

Regression analysis of longitudinal data with correlated censoring and observation times.

Longitudinal data occur in many fields such as the medical follow-up studies that involve repeated measurements. For their analysis, most existing approaches assume that the observation or follow-up times are independent of the response process either completely or given some covariates. In practice, it is apparent that this may not be true. In this paper, we present a joint analysis approach that allows the possible mutual correlations that can be characterized by time-dependent random effects. Estimating equations are developed for the parameter estimation and the resulted estimators are shown to be consistent and asymptotically normal. The finite sample performance of the proposed estimators is assessed through a simulation study and an illustrative example from a skin cancer study is provided.

The use of self-Reiki for stress reduction and relaxation.

Bukowski, Elaine L

2015-09-01

More than one-third of college students reported the desire for stress reduction techniques and education. The purpose of this study was to determine the effects of a 20-week structured self-Reiki program on stress reduction and relaxation in college students. Students were recruited from Stockton University and sessions were conducted in the privacy of their residence. Twenty students completed the entire study consisting of 20 weeks of self-Reiki done twice weekly. Each participant completed a Reiki Baseline Credibility Scale, a Reiki Expectancy Scale, and a Perceived Stress Scale (PSS) after acceptance into the study. The PSS was completed every four weeks once the interventions were initiated. A global assessment questionnaire was completed at the end of the study. Logs summarizing the outcome of each session were submitted at the end of the study. With the exception of three participants, participants believed that Reiki is a credible technique for reducing stress levels. Except for two participants, participants agreed that Reiki would be effective in reducing stress levels. All participants experienced stress within the month prior to completing the initial PSS. There was a significant reduction in stress levels from pre-study to post-study. There was a correlation between self-rating of improvement and final PSS scores. With one exception, stress levels at 20 weeks did not return to pre-study stress levels. This study supports the hypothesis that the calming effect of Reiki may be achieved through the use of self-Reiki.

Low rates of human papillomavirus (HPV) vaccination in low-income, minority adolescents may exacerbate racial disparities in cervical cancer incidence. Using electronic medical record data and chart abstraction, we examined correlates of HPV vaccine series initiation and completion among 7702 low-income and minority adolescents aged 11-21 receiving primary care at one of seven medical centers between May 1, 2007, and June 30, 2009. Our population included 61% African Americans, 13% Caucasians, 15% Latinas, and 11% other races; 90% receive public insurance (e.g., Medicaid). We used logistic regression to estimate the associations between vaccine initiation and completion and age, race/ethnicity, number of contacts with the healthcare system, provider documentation, and clinical site of care. Of the 41% of adolescent girls who initiated HPV vaccination, 20% completed the series. A higher proportion of girls aged 11-<13 (46%) and 13-<18 (47%) initiated vaccination than those aged 18-21 (28%). In adjusted analyses, receipt of other recommended adolescent vaccines was associated with vaccine initiation, and increased contact with the medical system was associated with both initiation and completion of the series. Conversely, provider failure to document risky health behaviors predicted nonvaccination. Manual review of a subset of unvaccinated patients' charts revealed no documentation of vaccine discussions in 67% of cases. Fewer than half of low-income and minority adolescents receiving health maintenance services initiated HPV vaccination, and only 20% completed the series. Provider failure to discuss vaccination with their patients appears to be an important contributor to nonvaccination. Future research should focus on improving both initiation and completion of HPV vaccination in high-risk adolescents.

The Pediatric Surgery fellow selection is a multi-layered process which has not included assessment of surgical dexterity. Data was collected prospectively as part of the 2016 Pediatric Surgery Match interview process. Applicants completed a questionnaire to document laparoscopic experience and fine motor skills activities. Actual laparoscopic skills were assessed using a simulator. Time to complete an intracorporeal knot was tabulated. An initial rank list was formulated based only on the ERAS application and interview scores. The rank list was re-formulated following the laparoscopic assessment. Un-paired T-test and regression were utilized to analyze the data. Forty applicants were interviewed with 18 matched (45%). The mean knot tying time was 201.31s for matched and 202.35s for unmatched applicants. Playing a musical instrument correlated with faster knot tying (p=0.03). No correlation was identified between knot tying time and either video game experience (p=0.4) or passing the FLS exam (p=0.78). Laparoscopic skills assessment lead to significant reordering of rank list (p=0.01). Laparoscopic skills performance significantly impacted ranking. Playing a musical instrument correlated with faster knot tying. No correlation was identified between laparoscopic performance and passing the FLS exam or other activities traditionally believed to improve technical ability. Prospective study. Level II.

We examined the agreement between a videoconference-based evaluation and a bedside evaluation in the management of acute traumatic wounds in an emergency department. Adult and paediatric patients with acute wounds of various severities to the face, trunk and/or extremities presenting to the emergency department within 24 hours of injury were enrolled. Research assistants transmitted video images of the wound to an emergency physician using a laptop computer. The physician completed a standard wound assessment form before conducting a bedside evaluation and then completing a second assessment form. The primary outcome measure was wound length and depth. We also assessed management decision-making. A total of 173 wounds were evaluated. The correlation coefficient between video and bedside assessments was 0.96 for wound length. The mean difference between the lengths was 0.02 cm (SD 0.91). Management of the wound would have been the same in 94% of cases. The agreement on wound characteristics and wound management ranged from 84-100%. The highest correlation was 0.92 in suture material used and the lowest correlation was 0.64 in wound type. The ability of video images to distinguish between a minor and non-minor wound, and predicting the need for hospital management, had high degrees of sensitivity and specificity. The study showed that wound characteristics and management decisions appear to correlate well between video and bedside evaluations.

Background. Physical activity (PA) is associated with health benefits and disease prevention and is often prescribed in managing many health conditions. Understanding the cultural influences is relevant in order to effectively promote PA. The objective of this study was to assess the level of PA among Saudi women, measured by daily step count, and the association between PA and health beliefs. Methods. A total of 161 eligible participants were asked to complete two questionnaires to assess health beliefs: Health Locus of Control (HLC) and Self-Efficacy Assessment Scale. Each participant was given a pedometer and a diary to record their daily PA for two weeks. Results. One hundred and five participants completed the two weeks pedometer data (mean age 26.3 ± 7.1 years, BMI 25 ± 4.2 kg/m2). The average pedometer score over two weeks was 5114 ± 2213 steps. Step count had strong correlation with self-efficacy (r s = 0.75), mild correlation with internal HLC (r s = 0.42), and mild negative correlation with external HLC (r s = −0.35). Conclusion. The study demonstrates high level of inactivity among Saudi females in reference to the international recommendation for minimum activity. The data also reveal an association between PA and health beliefs. Ultimately, such information can be used to design gender- and culture-sensitive interventions that could enhance adherence to PA.

"Complete Vocal Technique," or CVT, is an internationally widespread method for teaching voice. It classifies voicing into four types, referred to as "vocal modes," one of which is called "Overdrive." The physiological correlates of these types are unclear. This study presents an attempt to analyze its voice source and formant frequency characteristics. A male and a female expert of CVT sang a set of "Overdrive" and falsetto tones on the syllable /pᴂ/. The voice source could be analyzed by inverse filtering in the case of the male subject. Results showed that subglottal pressure, measured as the oral pressure during /p/ occlusion, was low in falsetto and high in "Overdrive", and it was strongly correlated with each of the voice source parameters. These correlations could be described in terms of equations. The deviations from these equations of the different voice source parameters for the various voice samples suggested that "Overdrive" phonation was produced with stronger vocal fold adduction than the falsetto tones. Further, the subject was also found to tune the first formant to the second partial in "Overdrive" tones. The results support the conclusion that the method used, to compensate for the influence of subglottal pressure on the voice source, seems promising to use for analyses of other CVT vocal modes and also for other types of phonation.

Binge eating (BE) has long been identified as a correlate of overweight and obesity. However, less empirical attention has been given to overeating with and without loss of control (LOC) in nonclinical samples. The goal of the present study was to examine the association of (1) established correlates of BE, namely, weight and shape concerns, dietary restraint, and negative affect, and (2) three additional correlates, disinhibition, hunger, and interoceptive awareness (IA), to overeating in a nonclinical sample of college women. Female students (n = 1,447) aged 18 to 21 years recruited from colleges in three Canadian metropolitan areas completed self-report questionnaires in class to assess sociodemographic and anthropomorphic characteristics, overeating, LOC, dietary restraint, negative affect, weight and shape concerns, IA, disinhibition, and hunger. The established correlates of BE were significant correlates of all types of overeating and explained 33 % of the variance. Disinhibition was the most strongly associated correlate of overeating. Findings suggest that established correlates of BE are associated with other types of overeating such as objective overeating (OOE), as are disinhibition and hunger.

[Purpose] The purpose of this study was to assess the correlation of gait parameters with fear of falling in stroke survivors. [Subjects] In total, 12 patients with stroke participated. [Methods] The subjects performed on a Biodex Gait Trainer 2 for 5 min to evaluate characteristic gait parameters. The kinematic gait parameters measured were gait speed, step cycle, step length, and time on each foot (step symmetry). All the subjects also completed a fall anxiety survey. [Results] Correlations between gait parameters and fear of falling scores were calculated. There was a moderate degree of correlation between fear of falling scores and the step cycle item of gait parameters. [Conclusions] According to our results, the step cycle gait parameter may be related to increased fall anxiety.

A 200-item, self-report personality disorder inventory (Coolidge Axis II Inventory; CATI) was administered to 52 married target subjects. Their spouses and a close friend completed a significant-other form about the targets. The mean correlation across all personality disorder scales was .51 for the targets-spouses, .36 for the targets-friends, and .41 for the spouses-friends. Twenty-eight target-spouse correlations were significant and ranged from .99 to -.40. The mean correlation for the individual 13 personality disorder scales was .46 for target-spouses and ranged from .63 for the histrionic scale to .27 for the paranoid scale. The results were interpreted as establishing a basis for significant other assessment of personality disorders.

Objective. To assess the impact of an advanced cardiac life support (ACLS) simulation on pharmacy student confidence and knowledge. Design. Third-year pharmacy students participated in a simulation experience that consisted of team roles training, high-fidelity ACLS simulations, and debriefing. Students completed a pre/postsimulation confidence and knowledge assessment. Assessment. Overall, student knowledge assessment scores and student confidence scores improved significantly. Student confidence and knowledge changes from baseline were not significantly correlated. Conversely, a significant, weak positive correlation between presimulation studying and both presimulation confidence and presimulation knowledge was discovered. Conclusions. Overall, student confidence and knowledge assessment scores in ACLS significantly improved from baseline; however, student confidence and knowledge were not significantly correlated.

The intergenerational correlation in weight: How genetic resemblance reveals the social role of families*

PubMed Central

Martin, Molly A.

2009-01-01

According to behavioral genetics research, the intergenerational correlation in weight derives solely from shared genetic predispositions, but complete genetic determinism contradicts the scientific consensus that social and behavioral change underlies the modern obesity epidemic. To address this conundrum, this article utilizes sibling data from the National Longitudinal Study of Adolescent Health and extends structural equation sibling models to incorporate siblings’ genetic relationships to explore the role of families’ social characteristics for adolescent weight. The article is the first to demonstrate that the association between parents’ obesity and adolescent weight is both social and genetic. Furthermore, by incorporating genetic information, the shared and social origins of the correlation between inactivity and weight are better revealed. PMID:19569401

Correlations after quantum quenches in the XXZ spin chain: failure of the generalized Gibbs ensemble.

We study the nonequilibrium time evolution of the spin-1/2 anisotropic Heisenberg (XXZ) spin chain, with a choice of dimer product and Néel states as initial states. We investigate numerically various short-ranged spin correlators in the long-time limit and find that they deviate significantly from predictions based on the generalized Gibbs ensemble (GGE) hypotheses. By computing the asymptotic spin correlators within the recently proposed quench-action formalism [Phys. Rev. Lett. 110, 257203 (2013)], however, we find excellent agreement with the numerical data. We, therefore, conclude that the GGE cannot give a complete description even of local observables, while the quench-action formalism correctly captures the steady state in this case.

Although identified as a significant public health concern, few studies have examined correlates of suicide risk in school-aged children. Recent studies show a relation between sluggish cognitive tempo (SCT) symptoms and a range of adverse outcomes linked to suicidal ideation, including depression, emotion dysregulation, lowered self-esteem, and peer problems/social withdrawal, yet no study to date has examined SCT in relation to suicide risk. We tested the hypothesis that SCT would be associated with suicide risk in a sample of 95 psychiatrically hospitalized children (74% male; 62% black) between the ages of 8 and 12 (M = 10.01, SD = 1.50). Parents completed measures of their child's psychiatric symptoms, including SCT and depression, as well as a measure of their own psychopathology. Children completed measures assessing loneliness and depression. Both parents and children completed measures of suicide risk. White children reported greater suicide risk than nonwhite children. After controlling for demographic characteristics, loneliness, parental psychopathology, and correlated psychiatric symptoms, including both parent- and child self-reported depressive symptoms, SCT remained uniquely associated with children's suicide risk. Results were consistent across both parent and child measures of suicide risk. This multi-informant study provides strong preliminary support for an association between SCT symptoms and suicide risk in psychiatrically hospitalized children, above and beyond loneliness, depression, and demographic characteristics. Findings are discussed in the context of the interpersonal theory of suicide. Additional studies are needed to replicate and extend these findings, with a particular need for studies that examine the cognitive processes and daydreaming content of individuals displaying elevated SCT symptomatology. © 2016 Association for Child and Adolescent Mental Health.

Pion correlations in relativistic heavy ion collisions at Heavy Ion Spectrometer Systems (HISS)

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

Christie, W.B. Jr.

This thesis contains the setup, analysis and results of experiment E684H Multi-Pion Correlations in Relativistic Heavy Ion Collisions''. The goals of the original proposal were: (1) To initiate the use of the HISS facility in the study of central Relativistic Heavy Ion Collisions (RHIC). (2) To perform a second generation experiment for the detailed study of the pion source in RHIC. The first generation experiments, implied by the second goal above, refer to pion correlation studies which the Riverside group had performed at the LBL streamer chamber. The major advantage offered by moving the pion correlation studies to HISS ismore » that, being an electronic detector system, as opposed to the Streamer Chamber which is a visual detector, one can greatly increase the statistics for a study of this sort. An additional advantage is that once one has written the necessary detector and physics analysis code to do a particular type of study, the study may be extended to investigate the systematics, with much less effort and in a relatively short time. This paper discusses the Physics motivation for this experiment, the experimental setup and detectors used, the pion correlation analysis, the results, and the conclusions possible future directions for pion studies at HISS. If one is not interested in all the details of the experiment, I believe that by reading the sections on intensity interferometry, the section the fitting of the correlation function and the systematic corrections applied, and the results section, one will get a fairly complete synopsis of the experiment.« less

2015-11-01

Psychological assessment has been used successfully to predict patient outcomes after cardiothoracic and bariatric surgery. The purpose of this study was to determine whether preoperative psychological assessment could be used to predict patient outcomes after temporomandibular joint arthroscopy. Consecutive patients with temporomandibular dysfunction (TMD) who could benefit from arthroscopy were enrolled in a prospective cohort study. All patients completed the Millon Behavior Medicine Diagnostic survey before surgery. The primary predictor variable was the preoperative psychological scores. The primary outcome variable was the difference in pain between the pre- and postoperative periods. The Spearman rank correlation coefficient and the Pearson product-moment correlation were used to determine the association between psychological factors and change in pain. Univariable and multivariable analyses were performed using a mixed-effects linear model and multiple linear regression. A P value of .05 was considered significant. Eighty-six patients were enrolled in the study. Seventy-five patients completed the study and were included in the final analyses. The mean change in visual analog scale (VAS) pain score 1 month after arthroscopy was -15.4 points (95% confidence interval, -6.0 to -24.7; P < .001). Jaw function also improved after surgery (P < .001). No association between change in VAS pain score and each of the 5 preoperative psychological factors was identified with univariable correlation analyses. Multivariable analyses identified that a greater pain decrease was associated with a longer duration of preoperative symptoms (P = .054) and lower chronic anxiety (P = .064). This study has identified a weak association between chronic anxiety and the magnitude of pain decrease after arthroscopy for TMD. Further studies are needed to clarify the role of chronic anxiety in the outcome after surgical procedures for the treatment of TMD. Copyright © 2015. Published by Elsevier Inc.

Schizophrenic patients demonstrate impairments in several key dimensions of cognition. These impairments are correlated with important aspects of functional outcome. While assessment of these cognition disorders is increasingly becoming a part of clinical and research practice in schizophrenia, there is no standard and easily administered test battery. The BACS (Brief Assessment of Cognition in Schizophrenia) has been validated in English language [Keefe RSE, Golberg TE, Harvey PD, Gold JM, Poe MP, Coughenour L. The Brief Assessment of Cognition in Schizophrenia: reliability, sensibility, and comparison with a standard neurocognitive battery. Schizophr. Res 2004;68:283-97], and was found to be as sensitive to cognitive dysfunction as a standard battery of tests, with the advantage of requiring less than 35 min to complete. We developed a French adaptation of the BACS and this study tested its ease of administration and concurrent validity. Correlation analyses between the BACS (version A) and a standard battery were performed. A sample of 50 stable schizophrenic patients received the French Version A of the BACS in a first session, and in a second session a standard battery. All the patients completed each of the subtests of the French BACS . The mean duration of completion for the BACS French version was 36 min (S.D.=5.56). A correlation analysis between the BACS (version A) global score and the standard battery global score showed a significant result (r=0.81, p<0.0001). The correlation analysis between the BACS (version A) sub-scores and the standard battery sub-scores showed significant results for verbal memory, working memory, verbal fluency, attention and speed of information processing and executive functions (p<0.001) and for motor speed (p<0.05). The French Version of the BACS is easier to use in French schizophrenic patients compared to a standard battery (administration shorter and completion rate better) and its good psychometric properties suggest that the French Version of the BACS may be a useful tool for assessing cognition in schizophrenic patients with French as their primary language.

FFQ are commonly used to rank individuals by their food and nutrient intakes in large epidemiological studies. The purpose of the present study was to develop and validate an FFQ to rank individuals participating in an ongoing Prospective Urban and Rural Epidemiological (PURE) study in Chile. An FFQ and four 24 h dietary recalls were completed over 1 year. Pearson correlation coefficients, energy-adjusted and de-attenuated correlations and weighted kappa were computed between the dietary recalls and the FFQ. The level of agreement between the two dietary assessment methods was evaluated by Bland-Altman analysis. Temuco, Chile. Overall, 166 women and men enrolled in the present study. One hundred men and women participated in FFQ development and sixty-six individuals participated in FFQ validation. The FFQ consisted of 109 food items. For nutrients, the crude correlation coefficients between the dietary recalls and FFQ varied from 0.14 (protein) to 0.44 (fat). Energy adjustment and de-attenuation improved correlation coefficients and almost all correlation coefficients exceeded 0.40. Similar correlation coefficients were observed for food groups; the highest de-attenuated energy adjusted correlation coefficient was found for margarine and butter (0.75) and the lowest for potatoes (0.12). The FFQ showed moderate to high agreement for most nutrients and food groups, and can be used to rank individuals based on energy, nutrient and food intakes. The validation study was conducted in a unique setting and indicated that the tool is valid for use by adults in Chile.

Meal skipping rates may be highest during young adulthood, a period of transition and development. Although these dietary behaviours may increase future risk of chronic disease, limited research has investigated correlates of meal skipping in young adults. A systematic literature search was conducted to identify studies that investigated correlates of meal skipping behaviours in young adults (aged 18-30 years). EBSCO host, MEDLINE Complete, Global Health, Scopus, EMBASE, Web of Science and Informit platforms were searched for eligible articles. Correlates were defined as any factor that was either associated with meal skipping or was self-reported by the participant to have an influence on meal skipping. Randomised controlled trials, prospective cohort studies, case-control studies, nested case-control studies, cross-sectional studies, and longitudinal studies were eligible for inclusion. Three-hundred and thirty-one articles were identified, 141 full-text articles assessed for eligibility, resulting in 35 included studies. Multiple methodological and reporting weaknesses were apparent in the reviewed studies with 28 of the 35 studies scoring a negative rating in the risk of bias assessment. Meal skipping (any meal), defined as the skipping of any meal throughout the day, was reported in 12 studies with prevalence ranging between 5 and 83%. The remaining 25 studies identified specific meals and their skipping rates, with breakfast the most frequently skipped meal 14-88% compared to lunch 8-57% and dinner 4-57%. Lack of time was consistently reported as an important correlate of meal skipping, compared with correlates such as cost and weight control, while sex was the most commonly reported associated correlate. Breakfast skipping was more common among men while lunch or dinner skipping being more common among women. This review is the first to examine potential correlates of meal skipping in young adults. Future research would benefit from stronger design and reporting strategies, using a standardised approach for measuring and defining meal skipping.

Complete event simulations of nuclear fission

NASA Astrophysics Data System (ADS)

Vogt, Ramona

2015-10-01

For many years, the state of the art for treating fission in radiation transport codes has involved sampling from average distributions. In these average fission models energy is not explicitly conserved and everything is uncorrelated because all particles are emitted independently. However, in a true fission event, the energies, momenta and multiplicities of the emitted particles are correlated. Such correlations are interesting for many modern applications. Event-by-event generation of complete fission events makes it possible to retain the kinematic information for all particles emitted: the fission products as well as prompt neutrons and photons. It is therefore possible to extract any desired correlation observables. Complete event simulations can be included in general Monte Carlo transport codes. We describe the general functionality of currently available fission event generators and compare results for several important observables. This work was performed under the auspices of the US DOE by LLNL, Contract DE-AC52-07NA27344.

The study's purpose was to determine if parental dental functional-health-literacy (FHL) related to child oral health; a secondary aim was to assess if errors in completing the questionnaire related to FHL and child oral health. Parents of pediatric clinic children (N=101) completed questionnaires; dental caries indices were recorded. Higher FHL was negatively correlated with worse child caries (r=-0.23), but not subjective oral health. Mean FHL seemed to differ by skip pattern (p=0.087), indicating it may be a potential FHL proxy. PMID:22685950

For the first time, the complete neutron multiplicity distribution has been measured in this study from the photofission of 235U induced by high-energy spallation γ rays arriving ahead of the neutron beam at the Los Alamos Neutron Science Center. The resulting average neutron multiplicity 3.80 ± 0.08 (stat.) neutrons per photofission is in general agreement with previous measurements. In addition, unique measurements of the prompt fission energy spectrum of the neutrons from photofission and the angular correlation of two-neutron energies emitted in photofission also were made. Finally, the results are compared to calculations with the complete event fission model FREYA.

There are limited validated food frequency questionnaires (FFQs) for infants and toddlers, most of which were evaluated in Europe or Oceania, and the ones available for use in the United States have important limitations. Our aim was to assess the validity of an FFQ developed for infants and toddlers. A semi-quantitative FFQ was developed that included 52 food items, their sources, and portion sizes. The FFQ inquired about diets over the previous 7 days. Its validity was assessed in a cross-sectional study. Participants completed the FFQ, followed by a 24-hour recall on two occasions with 1 week between data collection. A total of 296 caregivers of infants and toddlers aged 0 to 24 months enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children, Puerto Rico. Intake of nutrients and food groups were averaged for the two FFQs and the two 24-hour food recalls, and adjusted for energy intake. Spearman correlations were performed for intakes of energy, nutrients, and foods between administrations and between instruments. Correlation coefficients were de-attenuated to account for variation in the 24-hour recalls. A total of 241 participants completed the study. Intake of all nutrients and foods were significantly correlated between FFQs and 24-hour recalls and between the means of FFQs and 24-hour food recalls. The de-attenuated correlation for nutrients between the FFQs and 24-hour recalls ranged from 0.26 (folate) to 0.77 (energy), with a mean correlation of 0.53. The de-attenuated correlation for food groups between the FFQs and 24-hour recalls ranged from 0.28 (sweets) to 0.80 (breast milk), with a mean correlation of 0.55. When analyses were restricted to those consuming foods other than breast milk or formula (n=186), results were similar. This semi-quantitative FFQ is a tool that offers reasonably valid rankings for intake of energy, nutrients, foods, and food groups in this sample of infants and toddlers.

Runquist, Jennifer J; Reed, Pamela G

2007-03-01

This study examines the relationships of spiritually and physically related variables to well-being among homeless adults. A convenience sample of 61 sheltered homeless persons completed the Spiritual Perspective Scale, the Self-Transcendence Scale, the Index of Well-Being, and items measuring fatigue and health status. The data were subjected to correlational and multiple regression analysis. Positive, significant correlations were found among spiritual perspective, self-transcendence, health status, and well-being. Fatigue was inversely correlated with health status and well-being. Self-transcendence and health status together explained 59% of the variance in well-being. The findings support Reed's theory of self-transcendence, in which there is the basic assumption that human beings have the potential to integrate difficult life situations. This study contributes to the growing body of evidence that conceptualizes homeless persons as having spiritual, emotional, and physical capacities that can be used by health care professionals to promote well-being in this vulnerable population.

Life satisfaction and its correlates in older women with osteoarthritis.

Tak, Sunghee H; Laffrey, Shirley C

2003-01-01

To identify the relationships among functional disability, chronic daily stress, coping strategies, beliefs about personal control, social support, and life satisfaction in older women with osteoarthritis. A descriptive, correlational design was used. The study participants were 107 women aged 60 years or older. Study participants completed six survey questionnaires and a demographic form. Bivariate correlational analyses showed that older women with poorer functional ability experienced greater chronic daily stress, reported more frequent use of emotion-focused coping strategies, and had a higher chance health locus of control. A hierarchic regression analysis revealed that the perceived social support and internal health locus of control significantly contributed to the prediction of life satisfaction after demographic, illness-related, and stress-related variables were controlled. Stress management strategies matched to the participants' style of coping process can increase their sense of control over their health and enhance their social networks and activities.

OBJECTIVE. Reduced physical fitness secondary to heart failure (HF) may contribute to poor driving; reduced physical fitness is a known correlate of cognitive impairment and has been associated with decreased independence in driving. No study has examined the associations among physical fitness, cognition, and driving performance in people with HF. METHOD. Eighteen people with HF completed a physical fitness assessment, a cognitive test battery, and a validated driving simulator scenario. RESULTS. Partial correlations showed that poorer physical fitness was correlated with more collisions and stop signs missed and lower scores on a composite score of attention, executive function, and psychomotor speed. Cognitive dysfunction predicted reduced driving simulation performance. CONCLUSION. Reduced physical fitness in participants with HF was associated with worse simulated driving, possibly because of cognitive dysfunction. Larger studies using on-road testing are needed to confirm our findings and identify clinical interventions to maximize safe driving. PMID:26122681

[Purpose] This study assessed the relationships between peak toe flexor muscle strength, ankle dorsiflexion range of motion, and countermovement jump height. [Subjects and Methods] Eighteen healthy volunteers participated in the study. Each participant completed tests for peak toe flexor muscle strength, ankle dorsiflexion range of motion, and countermovement jump height. [Results] The results showed (1) a moderate correlation between ankle dorsiflexion range of motion and countermovement jump height and (2) a high correlation between peak first toe flexor muscle strength and countermovement jump height. Peak first toe flexor muscle strength and ankle dorsiflexion range of motion are the main contributors to countermovement jump performance. [Conclusion] These findings indicate that the measurement of peak first toe flexor muscle strength and ankle dorsiflexion range of motion may be useful in clinical practice for improving jump performance in athletes training for sports such as volleyball and basketball.

Emotional abuse is the most hidden and underestimated form of child maltreatment. We report an exploratory study in Saudi Arabia of the rate and types of emotional abuse among children and its association with selected variables. A convenience sample of 60 children aged 12-18 years was recruited from 3 malls in Jeddah. A specially designed, self-administered questionnaire was completed in confidence by the children with the consent of parents. Overall 90% of participants reported at least 1 form of rejecting emotional abuse and 61.7% at least 1 form of ignoring or terrorizing types of abuse. Chronic illness among parents was significantly positively correlated with terrorizing emotional abuse. There was a statistically significant negative correlation between mothers' relationship with the child and ignoring and terrorizing types of emotional abuse. Further research is needed about the community prevalence, correlates and consequences of child emotional abuse in Saudi Arabia.

The purpose of the current study was to investigate potential genetic and environmental correlations between working memory and three behavioral aspects of the attention network (i.e., executive, alerting, and orienting) using a twin design. Data were from 90 monozygotic (39% male) and 112 same-sex dizygotic (41% male) twins. Individual differences in working memory performance (digit span) and parent-rated measures of executive, alerting, and orienting attention included modest to moderate genetic variance, modest shared environmental variance, and modest to moderate nonshared environmental variance. As hypothesized, working memory performance was correlated with executive and alerting attention, but not orienting attention. The correlation between working memory, executive attention, and alerting attention was completely accounted for by overlapping genetic covariance, suggesting a common genetic mechanism or mechanisms underlying the links between working memory and certain parent-rated indicators of attentive behavior.

DNA index (DI) is considered an important prognostic factor in acute lymphoblastic leukaemia (ALL). We undertook this study to correlate DI with other presenting features and response to therapy. Of the 30 patients of ALL treated at our hospital and entered in this study, 15 were put on the aggressive MCP (multi center protocol) 841 protocol and equal number on the Alternate protocol. Eighteen achieved complete remission (13/15 on the former protocol and 5/15 on the later). DI was less than 0.8 in 8 (27%) patients, between 0.8 and 1.2 in 18 (60%) and more than 1.2 in 4 patients (13%). These figures are different from those reported in Caucasians. On multivariate regression analysis, the DI significantly correlated with percentage of blasts in peripheral blood (P = 0.0035). There was no correlation with outcome or response to treatment.

Aquatic plants are phylogenetically well dispersed across the angiosperms. Reproductive and other life-history traits of aquatic angiosperms are closely associated with specific growth forms. Hydrophilous pollination exhibits notable examples of convergent evolution in angiosperm reproductive structures, and hydrophiles exhibit great diversity in sexual system. In this study, we reconstructed ancestral characters of aquatic lineages based on the phylogeny of aquatic angiosperms. Our aim is to find the correlations of life form, pollination mode and sexual system in aquatic angiosperms. Hydrophily is the adaptive evolution of completely submersed angiosperms to aquatic habitats. Hydroautogamy and maleflower-ephydrophily are the transitional stages from anemophily and entomophily to hydrophily. True hydrophily occurs in 18 submersed angiosperm genera, which is associated with an unusually high incidence of unisexual flowers. All marine angiosperms are submersed, hydrophilous species. This study would help us understand the evolution of hydrophilous pollination and its correlations with life form and sexual system. PMID:25525810

Effects of geomagnetic activity and atmospheric power variations on quantitative measures of brain activity: Replication of the Azerbaijani studies

2010-04-01

This study replicates and extends the observations by Babayev and Allahveriyeva that changes in right hemispheric electroencephalographic activity are correlated with increases in geomagnetic activity. During the geomagnetically quiet interface between solar cycle 23 and 24 quantitative electroencephalographic (QEEG) measurements were completed for normal young adults in three separate experiments involving about 120 samples over 1.5 years. The most consistent, moderate strength correlations occurred for the changes in power within the gamma and theta ranges over the right frontal lobe. Real-time measures of atmospheric power obtained from polar orbiting satellites showed similar effects. The preferential involvement of the right frontal lobe and the regions subject to its inhibition with environmental energetic changes are consistent with the behavioural correlations historically associated with these conditions. They include increased incidence of emotional lability, erroneous reconstruction of experiences, social confrontations, and unusual perceptions.

Children's physical activity: an exploratory study of psychological correlates.

PubMed

Biddle, S; Armstrong, N

1992-02-01

Data are now accumulating that show that some children have apparently low levels of habitual physical activity, as measured by heart rate telemetry. However, relatively little is known about the likely correlates or determinants of such activity patterns. The purpose of this study, therefore, was to explore the extent to which activity levels were related to selected psychological factors. The heart rates of 11/12-year old boys and girls (N = 72) were monitored continuously for 12 hr on each of three school days. The same subjects completed psychological inventories assessing physical self-perceptions and motivation. Intrinsic motivation towards physical education and sport was significantly correlated with activity levels for boys. Motivational orientations also predicted activity, but differently for boys and girls. Evidence was found for a discrimination between 'active' and 'less active' girls on the basis of their physical self-perception and motivation scores.

Instantaneous phase estimation to measure weak velocity variations: application to noise correlation on seismic data at the exploration scale

Passive imaging from noise cross-correlation is a consolidated analysis applied at continental and regional scale whereas its use at local scale for seismic exploration purposes is still uncertain. The development of passive imaging by cross-correlation analysis is based on the extraction of the Green’s function from seismic noise data. In a completely random field in time and space, the cross-correlation permits to retrieve the complete Green’s function whatever the complexity of the medium. At the exploration scale and at frequency above 2 Hz, the noise sources are not ideally distributed around the stations which strongly affect the extraction of the direct arrivals from the noise cross-correlation process. In order to overcome this problem, the coda waves extracted from noise correlation could be useful. Coda waves describe long and scattered paths sampling the medium in different ways such that they become sensitive to weak velocity variations without being dependent on the noise source distribution. Indeed, scatters in the medium behave as a set of secondary noise sources which randomize the spatial distribution of noise sources contributing to the coda waves in the correlation process. We developed a new technique to measure weak velocity changes based on the computation of the local phase variations (instantaneous phase variation or IPV) of the cross-correlated signals. This newly-developed technique takes advantage from the doublet and stretching techniques classically used to monitor weak velocity variation from coda waves. We apply IPV to data acquired in Northern America (Canada) on a 1-km side square seismic network laid out by 397 stations. Data used to study temporal variations are cross-correlated signals computed on 10-minutes ambient noise in the frequency band 2-5 Hz. As the data set was acquired over five days, about 660 files are processed to perform a complete temporal analysis for each stations pair. The IPV permits to estimate the phase shift all over the signal length without any assumption on the medium velocity. The instantaneous phase is computed using the Hilbert transform of the signal. For each stations pair, we measure the phase difference between successive correlation functions calculated for 10 minutes of ambient noise. We then fit the instantaneous phase shift using a first-order polynomial function. The measure of the velocity variation corresponds to the slope of this fit. Compared to other techniques, the advantage of IPV is a very fast procedure which efficiently provides the measure of velocity variation on large data sets. Both experimental results and numerical tests on synthetic signals will be presented to assess the reliability of the IPV technique, with comparison to the doublet and stretching methods.

Vectorized data acquisition and fast triple-correlation integrals for Fluorescence Triple Correlation Spectroscopy

Ridgeway, William K; Millar, David P; Williamson, James R

2013-01-01

Fluorescence Correlation Spectroscopy (FCS) is widely used to quantitate reaction rates and concentrations of molecules in vitro and in vivo. We recently reported Fluorescence Triple Correlation Spectroscopy (F3CS), which correlates three signals together instead of two. F3CS can analyze the stoichiometries of complex mixtures and detect irreversible processes by identifying time-reversal asymmetries. Here we report the computational developments that were required for the realization of F3CS and present the results as the Triple Correlation Toolbox suite of programs. Triple Correlation Toolbox is a complete data analysis pipeline capable of acquiring, correlating and fitting large data sets. Each segment of the pipeline handles error estimates for accurate error-weighted global fitting. Data acquisition was accelerated with a combination of off-the-shelf counter-timer chips and vectorized operations on 128-bit registers. This allows desktop computers with inexpensive data acquisition cards to acquire hours of multiple-channel data with sub-microsecond time resolution. Off-line correlation integrals were implemented as a two delay time multiple-tau scheme that scales efficiently with multiple processors and provides an unprecedented view of linked dynamics. Global fitting routines are provided to fit FCS and F3CS data to models containing up to ten species. Triple Correlation Toolbox is a complete package that enables F3CS to be performed on existing microscopes. PMID:23525193

The aim of this study was to investigate the correlation between dental anxiety, salivary cortisol, and salivary alpha amylase (sAA) levels. Furthermore, the aim was to look into individual differences such as age, race, gender, any existing pain, or traumatic dental experience and their effect on dental anxiety. This study followed a cross-sectional design and included a convenience sample of 46. Every patient was asked to complete the Dental Anxiety Scale (DAS) and a basic demographic/dental history questionnaire. A saliva sample, utilizing the method of passive drooling, was then collected in 2-mL cryovials. Samples were analyzed for salivary cortisol and sAA levels by Salimetrics. Significant associations were observed between DAS scores and presence of pain and history of traumatic dental experience. However, no significant correlations were observed between DAS, cortisol, and sAA levels. Our study reconfirms that dental anxiety is associated with presence of pain and a history of traumatic dental experience. On the other hand, our study was the first to our knowledge to test the correlation between the DAS and sAA; nevertheless, our results failed to show any significant correlation between dental anxiety, cortisol, and sAA levels.

A description of the reservoir, production history, and fracturing techniques used leading up to this study is presented. Fracturing treatment analysis and production history matching were used to evaluate the reservoir and fracturing parameters for both completion types. The work showed that single fractures were created with the point-source (PS) completions, and multiple fractures resulted from many of the select-fire (SF) completions. A good correlation was developed between productivitymore » and the product of formation permeability, net fracture height, bottomhole pressure, and propped fracture length. Results supported the continued development of 10 wells using the PS concept with a more efficient treatment design, resulting in substantial cost savings.« less

To correlate emotional reactions to tooth loss with denture satisfaction attributes in elderly complete denture wearers. Total tooth loss is a serious life event, and poor oral health has an impact on daily life. Edentulism treated by rehabilitation with dentures can have a positive effect on patients' self-image and social behaviour. A group of 80 edentulous subjects undergoing routine prosthetic care in a Greek Department of Prosthetic Dentistry were interviewed using two structured questionnaires. The first questionnaire explored reactions to tooth loss, whereas the second measured their subjective experience of complete dentures. The responses to both questionnaires were compared using the statistical package SPSS v.17. The results showed significant correlation between aspects of tooth loss experience and complete denture satisfaction. Despite the fact that a substantial proportion of patients were satisfied with their complete dentures, some patients experienced increased social and psychological problems related to their edentulousness and the wearing of complete dentures. The aesthetic and functional aspects of complete dentures affected both patients' social behaviour and self-confidence. Total tooth loss was not only reflected in patient's social behaviour and self-image, but it had a complex and multifaceted impact on satisfaction from complete dentures. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

A Correlation of Community College Math Readiness and Student Success

NASA Astrophysics Data System (ADS)

Brown, Jayna Nicole

Although traditional college students are more prepared for college-level math based on college admissions tests, little data have been collected on nontraditional adult learners. The purpose of this study was to investigate relationships between math placement tests and community college students' success in math courses and persistence to degree or certificate completion. Guided by Tinto's theory of departure and student retention, the research questions addressed relationships and predictability of math Computer-adaptive Placement Assessment and Support System (COMPASS) test scores and students' performance in math courses, persistence in college, and degree completion. After conducting correlation and regression analyses, no significant relationships were identified between COMPASS Math test scores and students' performance (n = 234) in math courses, persistence in college, or degree completion. However, independent t test and chi-squared analyses of the achievements of college students who tested into Basic Math (n = 138) vs. Introduction to Algebra (n = 96) yielded statistically significant differences in persistence (p = .039), degree completion (p < .001), performance (p = .008), and progress ( p = .001), indicating students who tested into Introduction to Algebra were more successful and persisted more often to degree completion. In order to improve instructional methods for Basic Math courses, a 3-day professional development workshop was developed for math faculty focusing on current, best practices in remedial math instruction. Implications for social change include providing math faculty with the knowledge and skills to develop new instructional methods for remedial math courses. A change in instructional methods may improve community college students' math competencies and degree achievement.

Two samples of women aborting in New York and Connecticut during 1972 and 1973 were studied. In all, six hundred and fifty eight women about to undergo first and second trimester procedures completed a self-administered questionnaire. Items include: demographic, psychosocial and personality parameters, and a detailed review of the decision process leading to abortion. Analyses of the correlates of delay are organized around four components: acknowledgment of pregnancy; seeing a physician ; deciding to abort; and locating a clinic. Other analyses focus on the role of decisional conflict in delay. Methodological issues, implications for educational practice and for theory of decision-making are discussed.

The relationships among attachment style, self-concealment, and interpersonal distance were studied with 71 Japanese undergraduates (33 men and 38 women, ages 18 to 20 years, M = 18.7, SD= .6). Participants completed a questionnaire about Self-concealment and Attachment Styles (Secure, Anxious, and Avoidant). One week later, Interpersonal Distance, which individuals maintain between themselves and others, was measured by the stop-distance paradigm. Analysis showed that scores for more Anxious and Avoidant Attachment Styles were positively correlated with those for greater Self-concealment. Scores for greater Self-concealment and more Anxious Attachment Style were also correlated with longer Interpersonal Distance.

A comparison of correlation-length estimation methods for the objective analysis of surface pollutants at Environment and Climate Change Canada.

An objective analysis is one of the main components of data assimilation. By combining observations with the output of a predictive model we combine the best features of each source of information: the complete spatial and temporal coverage provided by models, with a close representation of the truth provided by observations. The process of combining observations with a model output is called an analysis. To produce an analysis requires the knowledge of observation and model errors, as well as its spatial correlation. This paper is devoted to the development of methods of estimation of these error variances and the characteristic length-scale of the model error correlation for its operational use in the Canadian objective analysis system. We first argue in favor of using compact support correlation functions, and then introduce three estimation methods: the Hollingsworth-Lönnberg (HL) method in local and global form, the maximum likelihood method (ML), and the [Formula: see text] diagnostic method. We perform one-dimensional (1D) simulation studies where the error variance and true correlation length are known, and perform an estimation of both error variances and correlation length where both are non-uniform. We show that a local version of the HL method can capture accurately the error variances and correlation length at each observation site, provided that spatial variability is not too strong. However, the operational objective analysis requires only a single and globally valid correlation length. We examine whether any statistics of the local HL correlation lengths could be a useful estimate, or whether other global estimation methods such as by the global HL, ML, or [Formula: see text] should be used. We found in both 1D simulation and using real data that the ML method is able to capture physically significant aspects of the correlation length, while most other estimates give unphysical and larger length-scale values. This paper describes a proposed improvement of the objective analysis of surface pollutants at Environment and Climate Change Canada (formerly known as Environment Canada). Objective analyses are essentially surface maps of air pollutants that are obtained by combining observations with an air quality model output, and are thought to provide a complete and more accurate representation of the air quality. The highlight of this study is an analysis of methods to estimate the model (or background) error correlation length-scale. The error statistics are an important and critical component to the analysis scheme.

Exploring Selective Exposure and Confirmation Bias as Processes Underlying Employee Work Happiness: An Intervention Study

Employee psychological capital (PsyCap), perceptions of organizational virtue (OV), and work happiness have been shown to be associated within and over time. This study examines selective exposure and confirmation bias as potential processes underlying PsyCap, OV, and work happiness associations. As part of a quasi-experimental study design, school staff (N = 69) completed surveys at three time points. After the first assessment, some staff (n = 51) completed a positive psychology training intervention. Results of descriptive statistics, correlation, and regression analyses on the intervention group provide some support for selective exposure and confirmation bias as explanatory mechanisms. In focusing on the processes through which employee attitudes may influence work happiness this study advances theoretical understanding, specifically of selective exposure and confirmation bias in a field study context.

To develop a visual analogue measure of self-esteem and test its psychometric properties. Two correlational studies involving samples of university students and aphasic speakers. Two hundred and forty-three university students completed multiple measures of self-esteem, depression and anxiety as well as measures of transitory mood and social desirability (Study 1). Two samples of aphasic speakers (N = 14 and N = 20) completed the Visual Analogue Self-Esteem Scale (VASES), the Rosenberg (1965) self-esteem scale and measures of depression and anxiety. (Study 2). Study 1 found evidence of good internal and test-retest reliability, construct validity and convergent and discriminant validity for a 10-item VASES. Study 2 demonstrated good internal reliability among aphasic speakers. The VASES is a short and easy to administer measure of self-esteem that possesses good psychometric properties.

Few epidemiologic studies have assessed health-related quality of life (HRQL) of asthma patients from a general population and it is unclear which instrument is best suitable for this purpose. We investigated the validity of the Asthma Quality of Life Questionnaire (AQLQ) and the SF-36 completed by individuals with asthma from the population-based SAPALDIA (Swiss study on air pollution and lung diseases in adults) cohort. The study included 258 participants with a physician-diagnosed asthma who had completed the AQLQ and SF-36. We assessed floor and ceiling effects, internal consistency reliability and cross-sectional validity with a priori hypotheses that correlations between the specific HRQL domains (e.g. "symptoms" or "physical functioning") and the corresponding external validation measures (respiratory symptoms, need for doctor visits, limitation in activities due to asthma and lung function) would capture similar aspects and be correlated moderately (> or = 0.3) to strongly (> or = 0.5), whereas non-corresponding domains be correlated weakly with each other (<0.3). The AQLQ showed pronounced ceiling effects with all median domain scores above 6 (scores varied from 1-7). For the SF-36, ceiling effects were present in 5 out of 8 domains. Cronbach's alpha was >0.7 for all AQLQ and SF-36 domains. Correlations between the AQLQ domains "respiratory symptoms", "activity limitation" and "environmental exposure", and the validation measures ranged from 0.29-0.57. Correlations between the "emotional function" domain and the validation measures were also in this range (0.31-0.55) and not as low as we hypothesized. For the SF-36, correlations between "physical functioning" and "role physical", and the validation measures ranged from 0.25-0.56, whereas "role emotional" and "mental health" correlated with these measures from 0.01-0.23. The AQLQ and the SF-36 showed fairly good internal consistency. Both instruments are limited by ceiling effects, but they appear less pronounced in the SF-36, which also shows a better discrimination between different aspects of HRQL. The SF-36 may therefore be a more valid measure of HRQL than the AQLQ when applied to individuals with asthma from the general population.

Objectives: The aim of this study was to evaluate the proportion of completed treatments and to study the factors affecting the full mouth dental rehabilitation in pediatric patients treated by undergraduate students at the College of Dental Medicine Teaching Clinics, University of Sharjah. Materials and Methods: A retrospective study was conducted on 270 children aged less than 12 years (mean age 7.6, SD 2.04). Comprehensive dental rehabilitation reports of child patients that were completed by final year dental undergraduate students from the year 2009 to 2011 were reviewed. Data on complete history, oral examination, dental charting, and treatment plan were collected from pediatric dentistry case sheet. Dental caries was charted using WHO 1997 criteria. Dental treatment needs and completion of dental care delivered to children involved in this study were assessed using DMFT/deft scores. Results: Percentages of treatment provided included completed restorations (94%) and space management (84%) in primary dentition, whereas 98% of restoration and 94% of required sealants were completed in permanent dentition. The percentage of completed dental treatment including sealant placement was 61%. Age of the child and the number of decayed teeth present before the start of the treatment significantly correlated with the children in the incomplete treatment category (P < 0.05). Conclusions: Therefore, a worthy dental care was provided in a holistic approach to the children attending College of Dental Medicine training clinics. Age of the child and the number of decayed teeth were the factors affecting dental rehabilitation in children aged 3–12 years. PMID:26236683

Data on long-term consequences of preterm birth on pain coping later in life are limited. To assess whether gestational age, birth weight and neonatal disease severity have effect on pain coping style in adolescents born preterm or with low birth weight. Observational, longitudinal study (Project On Preterm and SGA-infants, POPS-19). We analyzed data of 537 adolescents at the age of 19 years, who were born at a gestational age <32 weeks or with a birth weight <1500g. Participants completed the pain coping questionnaire (PCQ) that assesses pain coping strategies in three higher-order factors: approach ("to deal with pain"), problem-focused avoidance ("to disengage from pain") and emotion-focused avoidance ("expression of pain"). Furthermore, their pain coping effectiveness, pain controllability and emotional reactions to pain were assessed. All participants completed an IQ test. Univariate analysis showed no significant correlation between length of stay, sepsis and necrotizing enterocolitis and any of the higher-order factors. Approach was only correlated with IQ. Problem-focused avoidance was, in the multiple regression analysis (including gestational age, IVH and IQ), only correlated with IQ. For emotion-focused avoidance (including birth weight, SGA, IVH, respiratory support and IQ) three independent predictors remained: IVH was positively correlated, while respiratory support and IQ were negatively correlated with emotion-focused avoidance. Early neonatal characteristics and neonatal disease severity have limited effect on pain coping style in adolescence. Higher IQ was associated with the use of adaptive coping strategies, while maladaptive strategies were used less. Copyright © 2016. Published by Elsevier Ireland Ltd.

2011-01-01

To determine the relationship between napping and cognitive function in preschool-aged children. Daytime napping, nighttime sleep, and cognitive function were assessed in 59 typically developing children aged 3 to 5 years, who were enrolled in full-time childcare. Participants wore an actigraphy watch for 7 days to measure sleep and napping patterns and completed neuropsychological testing emphasizing attention, response control, and vocabulary. Parents of participants completed behavior ratings and sleep logs during the study. Sleep/wake cycles were scored with the Sadeh algorithm. Children who napped more on weekdays were also more likely to nap during weekends. Weekday napping and nighttime sleep were inversely correlated, such that those who napped more slept less at night, although total weekday sleep remained relatively constant. Weekday napping was significantly (negatively) correlated with vocabulary and auditory attention span, and weekday nighttime sleep was positively correlated with vocabulary. Nighttime sleep was also significantly negatively correlated with performance, such that those who slept less at night made more impulsive errors on a computerized go/no-go test. Daytime napping is actually negatively correlated with neurocognitive function in preschoolers. Nighttime sleep seems to be more critical for development of cognitive performance. Cessation of napping may serve as a developmental milestone of brain maturation. Children who nap less do not appear to be sleep deprived, especially if they compensate with increased nighttime sleep. An alternative explanation is that children who sleep less at night are sleep deprived and require a nap. A randomized trial of nap restriction would be the next step in understanding the relationship between napping and neurocognitive performance.

Pelvic floor muscle training (PFMT) is the recommended first-line treatment for women with urinary incontinence (UI). Success rates are variable and dependent on a number of factors. The development of an incontinence treatment motivation questionnaire (ITMQ) provides us with a tool to assess patient self-motivation with respect to PFMT and UI. The aim of this study was to determine the effect of women's self-motivation to perform PFMT on outcome. Women with stress predominant UI completed an ITMQ and a 24-h pad test and then underwent a 12-week course of supervised PFMT. At the end of their treatment they completed a patient global impression of improvement questionnaire (PGI-I) and a second 24-h pad test. The PGI-I scores and the difference in pad test weight correlated with the ITMQ according to Spearman's correlation coefficient. Sixty-five women were recruited. Thirty-two (49%) patients perceived themselves as having improved, 28 women (43%) did not experience any change in symptoms and 5 women (8%) felt that their symptoms deteriorated following treatment. When correlating the PGI-I with the ITMQ, 3 of the 5 domains: MQS1 (positive attitude for treatment; p = 0.003), MQS3 (frustration of living with incontinence; p = 0.002) and MQS4 (desire for treatment; p = 0.002) correlated significantly with outcome. Desire for treatment was the only domain to correlate with change in pad weight (p = 0.001). Self-motivation is essential in order to determine improved success rates with PFMT.

Measuring symptoms of post-traumatic stress disorder in people with intellectual disabilities: the development and psychometric properties of the Impact of Event Scale-Intellectual Disabilities (IES-IDs).

PubMed

Hall, James C; Jobson, Laura; Langdon, Peter E

2014-09-01

The aims of the study were to (1) revise the Impact of Event Scale-Revised for use with people with intellectual disabilities (IDs), creating the Impact of Event Scale-Intellectual Disabilities (IES-IDs), (2) assess the reliability of the IES-IDs, and (3) compare the IES-IDs to an existing measure trauma-related symptomatology, namely the Lancaster and Northgate Trauma Scale (LANTS), along with measures of anxiety and depression. Forty adults with IDs who had experienced at least one traumatic event were recruited and completed the IES-IDs and the LANTS on two occasions, separated by 2 weeks. Participants also completed the Glasgow Depression Scale and the Glasgow Anxiety Scale, along with the Trauma Information Form which was used to collect information about trauma history. Fifteen per cent of the sample had encountered five or more traumatic events. The IES-IDs and the LANTS had good to excellent internal consistency and test-retest reliability. Both measures correlated with self-report measures of depression and anxiety, although the strength of this correlation was greater with the LANTS. There was a significant positive correlation between trauma frequency and the IES-IDs, while trauma frequency did not correlate with the LANTS. Both the IES-IDs and the LANTS appear to have good reliability. There is a lack of well-developed questionnaires that can be used to assess symptoms of post-traumatic stress disorder (PTSD) in people with intellectual disabilities. The Impact of Event Scale-Revised was augmented creating the Impact of Event Scale-Intellectual Disabilities (IES-IDs). The IES-IDs was shown to have good psychometric properties. The IES-IDs was compared to the Lancaster and Northgate Trauma Scale (LANTS), but the LANTS did not correlate with trauma frequency. However, this study had a small sample size, and a much larger study is needed to examine the factor structure of both the IES-IDs and the LANTS. Future studies should attempt to recruit people with IDs who have a diagnosis of PTSD. © 2014 The British Psychological Society.

Dual-aspect monism à la Pauli and Jung perforates the completeness of physics

NASA Astrophysics Data System (ADS)

Atmanspacher, Harald

2012-12-01

In the mid 19th century, the physicist Wolfgang Pauli and the psychologist Carl Gustav Jung developed a philosophical position for the mind-matter problem that is today called dual-aspect monism. They conjectured a picture in which the mental and the material arise as two complementary aspects of one underlying psychophysically neutral reality to which they cannot be reduced and to which direct empirical access is impossible. This picture suggests structural, persistent,re-producible mind-matter correlations by splitting the underlying reality into aspects. In addition, it suggests induced, occasional, evasive mind-matter correlations above and below, respectively, those stable baseline correlations. These correlations, and the way they arise, suggest that the domain of the physical is not completely independent of the domain of the mental, and both are not independent from the assumed reality underlying them. Some ideas are presented of how these relationships might be conceived.

Wilson, Rozanne; Rochon, Elizabeth; Mihailidis, Alex; Leonard, Carol

2012-04-01

To examine how formal (i.e., employed) caregivers' use verbal and nonverbal communication strategies while assisting individuals with moderate to severe Alzheimer's disease (AD) during the successful completion of an activity of daily living (ADL). Based on the literature, the authors hypothesized that caregivers' use of 1 proposition, closed-ended questions, and repetition would be of most benefit. Twelve caregiver-AD dyads participated in this observational study. Each dyad was videorecorded on 6 separate occasions while completing handwashing. Handwashing sessions were transcribed and systematically coded for the use of communication strategies during completion of the ADL. Caregiver-AD dyads successfully completed 90% of all handwashing sessions, and caregivers employed a variety of communication strategies. Consistent with our hypotheses, during successful task completion, caregivers most frequently provided individuals with AD with 1 direction or idea (i.e., proposition) at a time, closed-ended questions, and paraphrased repetition. Caregivers also frequently used encouraging comments and the resident's name during the task; however, use of these strategies was not correlated to task success rate. This study adds to the limited body of evidence supporting the use of specific communication strategies by caregivers assisting individuals with moderate to severe AD during successful completion of ADLs.

MIDAS and HIT-6 French translation: reliability and correlation between tests.

PubMed

Magnoux, E; Freeman, M A; Zlotnik, G

2008-01-01

The aim was to evaluate the test-retest reliability of the French translation of the Migraine Disability Assessment (MIDAS) and Headache Impact Test (HIT)-6 questionnaires as applied to episodic and chronic headaches and to assess the correlation between these two questionnaires. The MIDAS and HIT-6 questionnaires, which assess the degree of migraine-related functional disability, are widely used in headache treatment clinics. The French translation has not been checked for test-retest reliability. MIDAS involves recall, over the previous 3 months, of the number of days with functional disability with regard to work and to home and social life. HIT-6 involves a more subjective and general assessment of headache-related disability over the previous 4 weeks. We expect that there may be greater impact recall bias for chronic headaches than for episodic headaches and considered it important to be able to determine if the reliability of these questionnaires is equally good for these two patient populations. Given that both questionnaires have the same objective, that of assessing headache impact, it was thought useful to determine if their results might show a correlation and if they could thus be used interchangeably. The study was approved by an external ethics committee. The subjects were patients who regularly visit the Clinique de la Migraine de Montréal, which specializes in the treatment of headaches. The MIDAS and HIT-6 questionnaires were completed by the patients during their regular visit. Twelve days later, the same questionnaires were mailed with a prepaid return envelope. Sixty-five patients were required in both the episodic and chronic headache groups, assuming an 80% questionnaire return rate. One hundred and eighty-five patients were enrolled, and 143 completed the study, 75 with episodic headaches and 68 with chronic headaches. The questionnaire return rate was 78.9%. On average, questionnaires were completed a second time 21 days after the first, with a median of 19 days. The Shrout-Fleiss intraclass correlation coefficients for MIDAS and HIT-6 were, respectively, 0.76 and 0.77 for episodic headaches and 0.83 and 0.80 for chronic headaches. The Pearson correlation coefficient between the MIDAS and HIT-6 questionnaires was 0.48 for episodic headaches and 0.58 for chronic headaches at the first compilation and 0.42 and 0.59 at the second compilation. The test-retest intraclass correlation of the French versions for both MIDAS and HIT-6 questionnaires indicates moderate reliability for episodic headache and substantial reliability for chronic headache. The correlation between the MIDAS and HIT-6 questionnaires is weak for episodic headaches, but approaches a level of 'good' for chronic headaches.

Revised multicultural perspective index and measures of depression, life satisfaction, shyness, and self-esteem.

Mowrer, Robert R; Parker, Keesha N

2004-12-01

In a 2002 publication, Mowrer and McCarver reported weak but significant correlations (r =.24) between scores on the Multicultural Perspective Index and scores on Neugarten, Havighurst, and Tobin's 1961 Life Satisfaction Index-A and the Life Satisfaction Scale developed in 1985 by Diener, Emmons, Larsen, and Griffin. Using 382 undergraduate students the present study reduced the Index from 42 to 29 items based on each item's correlation with total items. An additional 104 undergraduate students then completed the modified 29-item version, Rosenberg's Self-esteem Scale, Cheek and Buss's Shyness Scale, the Self-rating Depression Scale by Zung, and the Neugarten, et al. Life Satisfaction Index-A. Scores on the modified Index were negatively correlated with those on the Depression and Shyness scales and positively correlated with scores on the Self-esteem and Life Satisfaction scales (p< .05).

Testing the Zimbardo Time Perspective Inventory in the Chinese context.

Wang, Ya; Chen, Xing-Jie; Cui, Ji-Fang; Liu, Lu-Lu

2015-09-01

In this study, the authors evaluated the Chinese version of the Zimbardo Time Perspective Inventory (ZTPI). The ZTPI was tested among a sample of 303 university students. A subsample of 51 participants was then asked to complete the ZTPI again along with another set of questionnaires. The five-factor model of a 20-item short version of the ZTPI showed good model fit, internal consistency, and test-retest reliability. The 20-item Chinese version of the ZTPI also provided good validity, showing correlations with other variables in expected directions. Past-Positive was positively correlated with reappraisal and negatively correlated with suppression emotion regulation strategies, and Present-Hedonistic was positively correlated with reappraisal emotion regulation strategies. These findings indicate that the ZTPI is a reliable and valid instrument for measuring time perspective in the Chinese setting. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

Family-centred practices emphasize professional supports for forming partnerships with families in early intervention. The Measure of Processes of Care for Service Providers (MPOC-SP) measures the perceptions of paediatric service providers in supporting children and families. This study aimed to establish reliability of the Chinese version of the MPOC-SP (C-MPOC-SP) and to examine professional perceptions of family-centred practices in relation to professional discipline and years of experience. A convenience sample of 94 physical therapists, occupational therapists, speech-language pathologists, social workers and early childhood educators completed the C-MPOC-SP. Thirty-seven professionals completed the measure a second time within 2-4 weeks for test-retest reliability. Internal consistency and test-retest reliability were examined by Cronbach's α and intra-class correlation coefficient. Comparisons were made across professional disciplines by multivariate analyses of variance followed by analyses of variance. Relationships between years of experience and ratings of family-centred practices were examined by Pearson's correlation coefficients (r). Cronbach's α for items on each of the four scales of the C-MPOC-SP ranged from 0.80 to 0.92, indicating adequate internal consistency. Intra-class correlation coefficient between the initial and repeat completion of the C-MPOC-SP for each scale ranged from 0.56 to 0.77, indicating adequate to excellent test-retest reliability. Mean ratings for the Communicating Specific Information were significantly higher for physical therapists, occupational therapists and speech-language pathologists than for social workers (P = 0.001). The C-MPOC-SP scores were positively correlated with years of experience for all four scales (r = 0.23-0.38; P < 0.05). This study established adequate internal consistency and adequate to excellent test-retest reliability of the C-MPOC-SP in measuring perceptions of family centeredness of early intervention service providers. Cross-discipline differences were found in communicating specific information about the child. Higher perceptions of family centeredness were associated with more years of experience. The results support the utility of the C-MPOC-SP in professional education and programme evaluation of early intervention services in Taiwan. © 2017 John Wiley & Sons Ltd.

2018-05-25

Purpose Performance-based and disease indicators have been widely studied in firefighters; self-reported work role limitations have not. The aim of this study was to describe the distributions and correlations of a generic self-reported Work Limitations Questionnaire (WLQ-26) and firefighting-specific task performance-based tests. Methods Active firefighters from the City of Hamilton Fire Services (n = 293) were recruited. Participants completed the WLQ-26 to quantify on-the-job difficulties over five work domains: work scheduling (4 items), output demands (7 items), physical demands (8 items), mental demands (4 items), and social demands (3 items). A subset of participants (n = 149) were also assessed on hose drag and stair climb with a high-rise pack performance-based tests. Descriptive statistics and correlations were used to compare item/subscale performance; and to describe the inter-relationships between tests. Results The mean WLQ-26 item scores (/5) ranged from 4.1 to 4.4 (median = 5 for all items); most firefighters (54.5-80.5%) selected "difficult none of the time" response option on all items. A substantial ceiling effect was observed across all five WLQ-26 subscales as 44.0-55.6% were in the highest category. Subscale means ranged from 61.8 (social demands) to 78.7 (output demands and physical demands). Internal consistency exceeded 0.90 on all subscales. For the hose drag task, the mean time-to-completion was 48.0 s (SD = 14.5; range 20.4-95.0). For the stair climb task, the mean time-to-completion was 76.7 s (SD = 37.2; range 21.0-218.0). There were no significant correlations between self-report work limitations and performance of firefighting tasks. Conclusions The WLQ-26 measured five domains, but had ceiling effects in firefighters. Performance-based testing showed wider score range, lacked ceiling effects and did not correlate to the WLQ-26. A firefighter-specific, self-report role functioning scale may be needed to identify compromised work role capabilities in firefighters.

To test the hypothesis that emotional intelligence, as measured by the Bar-On Emotional Quotient Inventory (EQ-I) 125 (Multi Health Systems, Toronto, Ontario, Canada) personal inventory, would correlate with resident performance. Prospective survey. University-affiliated, multiinstitutional anesthesiology residency program. Current clinical anesthesiology years one to three (PGY 2-4) anesthesiology residents enrolled in the University of Pittsburgh Anesthesiology Residency Program. Participants confidentially completed the Bar-On EQ-I 125 survey. Results of the individual EQ-I 125 and daily evaluations by the faculty of the residency program were compiled and analyzed. There was no positive correlation between any facet of emotional intelligence and resident performance. There was statistically significant negative correlation (-0.40; P < 0.05) between assertiveness and the "American Board of Anesthesiology essential attributes" component of the resident evaluation. Emotional intelligence, as measured by the Bar-On EQ-I personal inventory, does not strongly correlate to resident performance as defined at the University of Pittsburgh.

2017-09-01

Numerous studies have demonstrated a relationship between adherence to Mediterranean diet and prevention of chronic degenerative diseases. The aim of this study was to validate a novel instrument to measure adherence to Mediterranean diet based on the literature (the MEDI-LITE score). Two-hundred-and-four clinically healthy subjects completed both the MEDI-LITE score and the validated MedDietScore (MDS). Significant positive correlation between the MEDI-LITE and the MDS scores was found in the study population (R = .70; p < .0001). Furthermore, statistically significant positive correlations were found for all the nine different food groups. According to the receiver operating characteristic (ROC) curve analysis, MEDI-LITE evidenced a significant discriminative capacity between adherents and non-adherents to the Mediterranean diet pattern (optimal cut-off point = 8.50; sensitivity = 96%; specificity = 38%). In conclusion, our findings show that the MEDI-LITE score well correlate with MDS in both global score and in most of the items related to the specific food categories.

Objectives Patient satisfaction impacts healthcare quality and outcomes. Residents play an important role in patient satisfaction at academic institutions. This study aims to assess residents’ patient satisfaction knowledge and determine which learning experiences contributed to their knowledge acquisition. Settings This study was conducted at a health science university in a large, urban, tertiary-care academic medical centre in the USA. Participants All residents from internal medicine (n=185) and paediatrics (n=156) were asked to participate. Design Residents completed a survey from April 2013 to December 2013 that assessed (1) knowledge of factors that impact patient satisfaction and (2) learning experiences that may have contributed to their understanding of the drivers of patient satisfaction (eg, experiential (personal or clinical) or didactics). Trainees identified the importance of factors in determining patient satisfaction on a five-point Likert scale; answers were compiled into a knowledge score. The score was correlated with prior personal/clinical experience and didactics. Results Of the 341 residents, 247 (72%) completed the survey. No difference was found in knowledge among training levels or residency programme. More than 50% incorrectly thought physician board certification, patient’s education, patient’s income and physician’s age impacted satisfaction. Personal experience, through hospitalisation of a relative or friend, was correlated with higher knowledge (67% vs 71%, p=0.03). Ninety-nine per cent (n=238) stated peer observation, and all stated faculty feedback impacted their patient satisfaction knowledge. Seventy-seven per cent (n=185) had attended didactics on satisfaction, but attendance did not correlate with higher scores. Conclusions Our study showed trainees have a few gaps in their patient satisfaction knowledge, and attending past educational sessions on patient satisfaction did not correlate with higher knowledge scores. Our data suggest that academic centres should leverage residents’ personal experiences, their observations of peers and faculty feedback to enhance patient satisfaction knowledge. PMID:28827266

Involvement in the criminal justice system is common among opioid-dependent people. This study aimed to determine prevalence and adolescent-onset correlates of adult imprisonment among opioid-dependent men and women in New South Wales, Australia. Participants were recruited from opioid substitution therapy clinics and completed a face-to-face, structured interview. Data were collected on demographic characteristics, family history, substance dependence and psychiatric disorders. Adolescent-onset correlates of adult incarceration (including interactions with gender) were examined using logistic regression. Opioid-dependent men were significantly more likely than opioid-dependent women to report adult imprisonment (66% vs 40%; P < 0.001). In a multivariable logistic regression model, older age, male gender, having completed high school education only, having dependent children or living independently prior to age 18 years, a history of juvenile detention and adolescent-onset opioid dependence were all significantly associated with increased odds of adult imprisonment. Adolescent-onset depression was associated with a halving of odds of adult imprisonment. The only variable for which we observed an interaction with gender was juvenile detention, which had a significantly greater impact on the odds of imprisonment for men than women. More than half of this sample of opioid dependent adults had a history of imprisonment. Variables that are associated with imprisonment in the general population, such as childhood maltreatment, were not important in predicting imprisonment in this sample. Further study is required to understand the interaction between sex and juvenile detention in predicting adult imprisonment. [Larney S, Cama E, Nelson E, Larance B, Degenhardt L.

Muscle dysmorphia (MD) is characterized by the pathological pursuit of muscularity and leanness, which includes eating- and exercise-related practices. The aim of this cross-sectional study was to identify correlations of MD symptomatology in natural bodybuilders. An online survey assessing diet, supplementation and training practices, and MD and eating disorder symptoms was completed by male bodybuilders with recent experience competing in a drug-tested competition. Sixty participants (age 29.6±7.1 years) completed the survey. Eating disorder scores (β=.298), rate of pre-competition weight loss (β=.307) and number of competitions (β=-.257) were significant predictors of MD. The association between the EAT-26 and MDDI underscores the salience of disordered eating pathology in presentations of MD. Supporting this, greater rate of pre-competition weight loss, which may reflect disordered eating practices, is also associated with MD symptomatology. The inverse association of competition experience suggests novice bodybuilders may display increased MD symptomatology. Copyright © 2017 Elsevier Ltd. All rights reserved.

Internet sexuality research with rural men who have sex with men: can we recruit and retain them?

PubMed

Bowen, Anne

2005-11-01

This study examines the utility of internet banner ads for recruiting rural MSM and identifies correlates of internet HIV risk survey initiation and completion. Banner ads were shown on a popular internet dating site for one month and resulted in 1,045 rural MSM, from 49 States, Canada, Australia/New Zealand, and 5 from other countries initiating the questionnaire. Logistic regression indicated that progression beyond screening questions was negatively related to "expecting pay, but not being paid" and positively related to "using chat rooms to find friends" and identifying as gay. Linear regression indicated that the absolute number of responses by consenting participants was positively correlated with reimbursement, number of sexual partners, motivated by money, and having been HIV tested. Overall, this sample represents one of the largest rural MSM samples; survey completion was high and strengthened by reimbursement and possibly by awareness of HIV risk. Generalizability was limited by low participation of minority and non-gay identified MSM.

Western acculturation has been implicated in the development of eating disorders among populations living outside Europe and North America. This study explored the relationship between Western acculturation, in-group/out-group evaluations and eating disorders symptoms among female citizens of the United Arab Emirates (UAE). Emirati college women (N = 209) completed an affective priming task, designed to implicitly assess in-group (Emirati) and out-group (American) evaluations. Participants also completed the Westernization Survey, a widely used self-report measure of acculturation, and the Eating Attitudes Test (EAT-26). Across the whole sample, out-group positivity was correlated with higher levels of eating disorder symptoms. Participants classified as at risk for eating disorders showed a clear out-group preference (out-group positivity greater than in-group positivity). Western acculturation was also positively correlated with eating disorder symptoms. Overall, these findings lend further support to the acculturation hypothesis of eating disorders in the context of Emirati college women.

The present study explored the role of parents' in-session and out-session involvement in CBT for anxious children. Fifty 8- to 12-year-old children with a principal DSM-IV anxiety disorder participated in a group CBT program. Parental involvement in the therapy was assessed by the clinician and the children and parents completed a standardized anxiety scale as the main therapy outcome measure, at pre- and post-intervention. In addition, the parents completed questionnaires to evaluate a number of possible correlates of parental involvement, namely, child's anxiety symptoms intensity and interference, parental beliefs about anxiety, expectancies regarding the efficacy of the intervention, and parental anxiety. The results indicated that the parents were moderately involved in the therapy and that socio-economic status and parental beliefs about anxiety were significant correlates of parental involvement. Finally, partial support was found for the idea that parents' involvement in the therapy might have a positive impact on therapy outcome.

Background: Effective leadership is essential to passing through obstacles facing the health field.The current health care system in Iran has major problems and gaps in the field of effective leadership. The aim of this study was to evaluate hospital managers’ leadership style through selfassessment and to determine the correlation between leadership styles with healthcare executives’ leadership readiness and leadership effectiveness. Methods: In this cross-sectional study a self-administered questionnaire completed by all internal healthcare executives of all teaching and non-teaching hospitals affiliated to Iran University of Medical Sciences. Questionnaire was composed to determine demographic information, leadership style questions, leadership effectiveness and leadership readiness. Descriptive statistics and Pearson correlation coefficient were used for data analysis. Results: According to the findings, the dominant style of healthcare executives was transformational leadership style (with a score of 4.34). The leadership effectiveness was estimated at about 4.36 that shows the appropriate level of leadership effectiveness. There was a significant correlation (correlation coefficient of 0.244) between leadership readiness and transformational leadership style (p<0.05). Also, there was a significant correlation between leadership effectiveness with transformational (0.051) and transactional (0.216) styles. Conclusion: There was a correlation between leadership readiness and leadership effectiveness with leadership styles. Application of this research will be crucial to universities and healthcare executives. This study suggests that strengthening the scientific basis is essential for leadership readiness and leadership effectiveness in healthcare system. PMID:26000260

To investigate whether fruit and vegetable (F&V) intake in 11-year-olds, and social-environmental correlates of F&V intake such as parental modelling and encouragement, family food rules and home availability, differ according to general parenting styles in Belgium, The Netherlands, Portugal and Spain. Cross-sectional study. Primary schools in four countries. Pupils and one of their parents completed questionnaires to measure F&V intake, related social-environmental correlates and general parenting styles. The sample size was 4555 (49.3 % boys); 1180 for Belgium, 883 for The Netherlands, 1515 for Portugal and 977 for Spain. Parenting styles were divided into authoritative, authoritarian, indulgent and neglectful. No differences were found in F&V intake across parenting styles and only very few significant differences in social-environmental correlates. The authoritarian (more parental encouragement and more demands to eat fruit) and the authoritative (more availability of fruit and vegetables) parenting styles resulted in more favourable correlates. Despite earlier studies suggesting that general parenting styles are associated with health behaviours in children, the present study suggests that this association is weak to non-existent for F&V intakes in four different European countries.

The purpose of this research was to provide further evidence for the construct validity (i.e., convergent, concurrent, and discriminant validity) of the Prosocial and Antisocial Behaviour in Sport Scale (PABSS), an instrument that has four subscales measuring prosocial and antisocial behaviour toward teammates and opponents. We also investigated test-retest reliability and stability of the PABSS. We conducted three studies using athletes from a variety of team sports. In Study 1, participants (N = 129) completed the PABSS and measures of physical and verbal aggression, hostility, anger, moral identity, and empathy; a sub-sample (n = 111) also completed the PABSS one week later. In Study 2, in addition to the PABSS, participants (N = 89) completed measures of competitive aggressiveness and anger, moral attitudes, moral disengagement, goal orientation, and anxiety. In Study 3, participants (N = 307) completed the PABSS and a measure of social goals. Across the three studies, the four subscales evidenced the hypothesised relationships with a number of variables. Correlations were large between the two antisocial behaviours and small between the two prosocial behaviours. Overall, the findings supported the convergent, concurrent, and discriminant validity of the scale, provided evidence for its test-retest reliability and stability, and suggest that the instrument is a valid and reliable measure of prosocial and antisocial behaviour in sport.

Job strain (i.e., high job demands combined with low job control) is a frequently used indicator of harmful work stress, but studies have often used partial versions of the complete multi-item job demands and control scales. Understanding whether the different instruments assess the same underlying concepts has crucial implications for the interpretation of findings across studies, harmonisation of multi-cohort data for pooled analyses, and design of future studies. As part of the 'IPD-Work' (Individual-participant-data meta-analysis in working populations) consortium, we compared different versions of the demands and control scales available in 17 European cohort studies. Six of the 17 studies had information on the complete scales and 11 on partial scales. Here, we analyse individual level data from 70 751 participants of the studies which had complete scales (5 demand items, 6 job control items). We found high Pearson correlation coefficients between complete scales of job demands and control relative to scales with at least three items (r > 0.90) and for partial scales with two items only (r = 0.76-0.88). In comparison with scores from the complete scales, the agreement between job strain definitions was very good when only one item was missing in either the demands or the control scale (kappa > 0.80); good for job strain assessed with three demand items and all six control items (kappa > 0.68) and moderate to good when items were missing from both scales (kappa = 0.54-0.76). The sensitivity was > 0.80 when only one item was missing from either scale, decreasing when several items were missing in one or both job strain subscales. Partial job demand and job control scales with at least half of the items of the complete scales, and job strain indices based on one complete and one partial scale, seemed to assess the same underlying concepts as the complete survey instruments.
