    Latent toxoplasmosis, the life-long presence of dormant stages of Toxoplasma in immunoprivileged organs and of anamnestic IgG antibodies in blood, affects about 30% of humans. Infected subjects have an increased incidence of various disorders, including schizophrenia. Several studies, as well as the character of toxoplasmosis-associated disturbance of neurotransmitters, suggest that toxoplasmosis could also play an etiological role in Obsessive-Compulsive Disorder (OCD). The aim of the present cross-sectional study performed on a population of 7471 volunteers was to confirm the association between toxoplasmosis and OCD, and toxoplasmosis and psychological symptoms of OCD estimated by the standard Obsessive-Compulsive Inventory-Revised (OCI-R). Incidence of OCD was 2.18% (n=39) in men and 2.28% (n=83) in women. Subjects with toxoplasmosis had about a 2.5 times higher odds of OCD and about a 2.7 times higher odds of learning disabilities. The incidence of 18 other neuropsychiatric disorders did not differ between Toxoplasma-infected and Toxoplasma-free subjects. The infected subjects, even the OCD-free subjects, scored higher on the OCI-R. Examined subjects provided the information about their toxoplasmosis and OCD statuses themselves, which could result in underrating the strength of observed associations. The results confirmed earlier reports of the association between toxoplasmosis and OCD. They also support recent claims that latent toxoplasmosis is in fact a serious disease with many impacts on quality of life of patients. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    To compare the ceiling effect of the Lysholm and IKDC subjective scores for assessing functional outcome after ACL reconstruction and evaluated the correlation with the one-leg hop test. A total of 134 patients who underwent ACL reconstruction between 2007 and 2011 were enrolled in this study. All patients fulfilled the postoperative 6- and 12-month evaluations. The ceiling effect of the Lysholm and IKDC subjective scores was assessed, and the correlations between two scales and one-leg hop test were analysed. For the entire sample, the ceiling effect for the Lysholm score was 14.9% and 30.6% at 6 and 12 months postoperatively. The values for the IKDC subjective score were 5.2% and 17.2%, respectively. In all subjects, the correlation coefficients [95% confidence intervals] between the IKDC subjective score and one-leg hop test at 6 and 12months (r=0.492, [0.34 to 0.62]; r=0.296, [0.12 to 0.46]) were higher than those for the Lysholm score (r=0.355, [0.18 to 0.51]; r=0.241, [0.06 to 0.41]), respectively.(pceiling effect and the correlation with the LSI. However, the concern that the ceiling effect of the Lysholm score was greater than the IKDC subjective score, should be addressed in assessing the patient's functional status postoperatively.

    Full Text Available Aim: To study the Framingham cardiovascular risk assessment scores in subjects with diabetes and their association with diabetic retinopathy in subjects with diabetes. Materials and Methods: In this population-based prospective study, subjects with diabetes were recruited (n=1248; age ≥40 years. The Framingham cardiovascular risk scores were calculated for 1248 subjects with type 2 diabetes. The scores were classified as high risk (>10%, and low risk (<10%. Results: Out of the 1248 subjects, 830 (66.5% patients had a low risk of developing cardiovascular disease (CVD in 10 years and 418 (33.5% had a high risk of developing CVD in 10 years. The risk of developing CVD was more in males than females (56.8% vs. 7% The prevalence of both diabetic retinopathy and sight-threatening retinopathy was more in the high-risk group (21% and 4.5%, respectively. The risk factors for developing diabetic retinopathy were similar in both the groups (low vs. high - duration of diabetes (OR 1.14 vs. 1.08, higher HbA1c (OR 1.24 vs. 1.22, presence of macro- and microalbuminuria (OR 10.17 vs. 6.12 for macro-albuminuria and use of insulin (OR 2.06 vs. 4.38. The additional risk factors in the high-risk group were presence of anemia (OR 2.65 and higher serum high density lipoprotein (HDL cholesterol (OR 1.05. Conclusion: Framingham risk scoring, a global risk assessment tool to predict the 10-year risk of developing CVD, can also predict the occurrence and type of diabetic retinopathy. Those patients with high CVD scores should be followed up more frequently and treated adequately. This also warrants good interaction between the treating physician/cardiologist and the ophthalmologist.

    The current study aimed to identify the predictive values of psychological factors that are evaluated by the Symptoms Checklist-90 (SCL-90) for acute mountain sickness (AMS). The subjects (n=285, non-acclimatized young Chinese men), who were recruited in July 2013, completed a case report questionnaire. In addition, their vital signs (heart rate [HR], blood pressure and pulse oxygen saturation) were measured, and their psychological factors were examined using the SCL-90 at sea level. AMS was diagnosed using the Lake Louise self-assessment scoring system in the morning of the second day after their arrival at 3450m. Of the nine factors of the SCL-90, the AMS patients (AMS score≥3) were characterized by significantly higher scores for baseline somatization [14.0 (5.0) vs. 13.0 (3.0), psomatization (r=0.316, psomatization score (odds ratio=1.129, p=0.001) was an independent predictor of AMS. Furthermore, some non-AMS often-occurred symptoms (paresthesia, shortness of breath, reduced activity and tinnitus) were also found to be associated with the baseline SCL-90 scores. AMS is correlated with the baseline somatization score at sea level, which was measured using the SCL-90. A higher baseline somatization score is also an independent predictor of AMS.

    Full Text Available Purpose: At our institution, speculation amongst medical students and faculty exists as to whether team-based learning (TBL can improve scores on high-stakes examinations over traditional didactic lectures. Faculty with experience using TBL developed and piloted a required TBL blood disorders (BD module for third-year medical students on their pediatric clerkship. The purpose of this study is to analyze the BD scores from the NBME subject exams before and after the introduction of the module. Methods: We analyzed institutional and national item difficulties for BD items from the NBME pediatrics content area item analysis reports from 2011 to 2014 before (pre and after (post the pilot (October 2012. Total scores of 590 NBME subject examination students from examinee performance profiles were analyzed pre/post. t-Tests and Cohen's d effect sizes were used to analyze item difficulties for institutional versus national scores and pre/post comparisons of item difficulties and total scores. Results: BD scores for our institution were 0.65 (±0.19 compared to 0.62 (±0.15 nationally (P=0.346; Cohen's d=0.15. The average of post-consecutive BD scores for our students was 0.70(±0.21 compared to examinees nationally [0.64 (±0.15] with a significant mean difference (P=0.031; Cohen's d=0.43. The difference in our institutions pre [0.65 (±0.19] and post [0.70 (±0.21] BD scores trended higher (P=0.391; Cohen's d=0.27. Institutional BD scores were higher than national BD scores for both pre and post, with an effect size that tripled from pre to post scores. Institutional BD scores increased after the use of the TBL module, while overall exam scores remained steadily above national norms. Conclusions: Institutional BD scores were higher than national BD scores for both pre and post, with an effect size that tripled from pre to post scores. Institutional BD scores increased after the use of the TBL module, while overall exam scores remained steadily above

    The objective of the study was to identify associations between a history of obstetrical complications (OCs) and the future development of symptoms indicating risk of psychosis (At Risk Mental State - ARMS). The frequency of OCs was assessed in 66 ARMS subjects, 50 subjects with the first episode of schizophrenia (FES) and 50 healthy controls. Obstetrical data was obtained from medical documentation and evaluated with the Lewis and Murray Scale. Definite OCs, according to the Lewis and Murray Scale, occurred significantly more frequently in the ARMS group compared to the controls (χ(2) = 7.79, p = 0.005; OR = 4.20, 95% CI = 1.46-12.11), as well as in the FES subjects compared to the controls (χ(2) = 8.39, p = 0.004; OR = 4.64, 95% CI = 1.56-13.20). Apgar scores in the first (Apgar 1) and the fifth minute after birth (Apgar 5) were significantly lower in the FES subjects compared to the controls (for Apgar 1 score Z = 4.439, p Apgar 5 score Z = 5.250, p Apgar 5 scores compared to the healthy controls (Z = 3.458, p = 0.0016). The results indicate that OCs and low Apgar 5 score should be considered important factors in identifying subjects at risk of developing psychosis. Copyright © 2013 Elsevier Ltd.

    Full Text Available Background. Morbidly obese patients demonstrate altered olfactory acuity. There has been no study directly assessing Body Mass Index (BMI in patients with olfactory dysfunction. Our purpose was to compare BMI in a group of patients with subjective olfactory dysfunction to those without subjective olfactory complaints. Methods. Retrospective matched case-control study. Sixty patients who presented to a tertiary care otolaryngology center with subjective smell dysfunction over one year were identified. Neoplastic and obstructive etiologies were excluded. Demographics, BMI, and smoking status were reviewed. Sixty age, gender, and race matched control patients were selected for comparison. Chi-square testing was used. Results. 48 out of 60 patients (80% in the olfactory dysfunction group fell into the overweight or obese categories, compared to 36 out of 60 patients (60% in the control group. There was a statistically significant difference between the olfactory dysfunction and control groups for this stratified BMI (p= 0.0168.  Conclusion. This study suggests high BMI is associated with olfactory dysfunction. Prospective clinical research should examine this further to determine if increasing BMI may be a risk factor in olfactory loss and to elucidate what role olfactory loss may play in diet and feeding habits of obese patients.

    Pneumonia is most frequently produced by the microaspiration of flora that colonizes the oropharynx. Etiological diagnosis of pneumonia is infrequent in clinical practise and empirical treatment should be prescribed. The aims of the present study were to determine the factors associated with oropharynx colonization by uncommon microorganisms (UM) and to develop a predictive model. A cross-sectional study that included all pa-tients living in one long-term care facilities was developed. Demographic, comorbidities, basal functional status and clinical data were collected. To determinate the oropharyngeal colonization, a single sample of pharynx was obtained for each subject using a cotton swab. A total of 221 subjects were included, mean age 86.27 (SD 8.05) years and 157 (71%) were female. In 32 (14.5%) subjects UM flora was isolated, Gram-negative bacilli in 16 (7.2%) residents, and Staphylococcus aureus in 16 (7.2%). The predictive model included the presence of hypertension, neuromuscular disease, Barthel <90 and use of PEG. The BAHNG score (BArthel, Hypertension, Neuromuscular, Gastrostomy), showed an area under the curve of 0.731 (CI 95% 0.643-0.820; p<0.001). We have classified patients according to this score in low (0-2 points), intermediate (3-5 points) and high risk (≥ 6). The probability of UM colonization in the oropharyngeal based on this classification is 4.1%, 15.8% and 57.1% for low, intermediate and high risk, respectively. The BAHNG score could help in the identifications of elderly patients with high risk of colonization by UM. In case of pneumonia the evaluation of the subject through this score could help in the initial decisions concerning antibiotic treatment.

  19. Predictive Power of Primary and Secondary School Success Criterion on Transition to Higher Education Examination Scores

    Full Text Available It is seen that education has a significant effect that changes an individual’s life in our country in which education is a way of moving up the social ladder. In order to continue to a higher education program after graduating from high school, students have to succeed in transition to higher education examination. Thus, the entrance exam is an important factor to determine the future of the students. In our country, middle school grades and high school grade point average that is added to university placement score are also determinants. When spiral structure of our curriculum is considered, it is expected that related courses’ grades at middle school will predict the scores obtained from the first stage of transition to higher education exam (YGS. Since high school grade point average forms university placement score, being aware of how related courses’ achievement scores at secondary school predict raw scores of YGS subtests is significant in terms of our education system’s feedback and integrity. As a result, observing students’ achievement scores in related courses during their middle and high school education longitudinally and predicting raw scores on the subtests of the first stage of university entrance exam, YGS, from middle school and high scool achievement scores are substantial with regards to provide feedback to our education system. Because of those reasons, the predictive power of 7th - 12th grade year-end grade point averages ofstudents who took YGS in 2013 on their 2013 YGS subtests’ raw scvores is examined. Students who took YGS exam in Ankara province at 2012-2013 school year formed the aimed population of this study and 533 students who took YGS exam in 2013 in Altındağ district of Ankara formed target population of the study. Data was obtained from 533 students at three different schools in Altındağ district of Ankara province. Stepwise multiple regression analysis was used to answer research questions

    Two versions of the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation form currently exist: the original version (1999) and a recently modified pediatric-specific version (2011). Comparison of the pediatric IKDC with the adult version in the adult population may reveal that either version could be used longitudinally. We hypothesize that the scores for the adult IKDC and pediatric IKDC will not be clinically different among adult patients aged 18 to 50 years. Randomized crossover study design. Level 2. The study consisted of 100 participants, aged 18 to 50 years, who presented to orthopaedic outpatient clinics with knee problems. All participants completed both adult and pediatric versions of the IKDC in random order with a 10-minute break in between. We used a paired t test to test for a difference between the scores and a Welch's 2-sample t test to test for equivalence. A least-squares regression model was used to model adult scores as a function of pediatric scores, and vice versa. A paired t test revealed a statistically significant 1.6-point difference between the mean adult and pediatric scores. However, the 95% confidence interval (0.54-2.66) for this difference did not exceed our a priori threshold of 5 points, indicating that this difference was not clinically important. Equivalence testing with an equivalence region of 5 points further supported this finding. The adult and pediatric scores had a linear relationship and were highly correlated with an R2 of 92.6%. There is no clinically relevant difference between the scores of the adult and pediatric IKDC forms in adults, aged 18 to 50 years, with knee conditions. Either form, adult or pediatric, of the IKDC can be used in this population for longitudinal studies. If the pediatric version is administered in adolescence, it can be used for follow-up into adulthood.

This was a prospective cohort observational study in an urban, academic, specialized care center. Participants were ambulatory, nonhospitalized adults with CF. Main Outcome Measures. Mobility was assessed monthly by the Life-Space Assessment (LSA questionnaire and quarterly by pedometer. Lung function was assessed by spirometry. Results. Twenty-seven subjects participated. Subjects recorded mean pedometer steps of 20,213 ± 11,331 over three days and FEV1% predicted of 77.48% ± 22.60% over one year. The LSA score at enrollment was correlated with initial pedometer steps (r=0.42 and P=0.03, and mean LSA score over one year was correlated with mean number of steps (r=0.51 and P=0.007. LSA mobility and pedometer scores were correlated with FEV1% predicted at enrollment and throughout the study. Conclusions. Mobility and physical activity measured by LSA questionnaire and pedometer are positively associated with lung function in adults with CF. This study confirms the importance of mobility and physical activity and supports the utility of a simple office-based questionnaire as a measure of mobility in adults with CF.

    Freezing of gait (FoG) is common in Parkinsonian gait and strongly relates to falls. Current clinical FoG assessments are patients' self-report diaries and experts' manual video analysis. Both are subjective and yield moderate reliability. Existing detection algorithms have been predominantly designed in subject-dependent settings. In this paper, we aim to develop an automated FoG detector for subject independent. After extracting highly relevant features, we apply anomaly detection techniques to detect FoG events. Specifically, feature selection is performed using correlation and clusterability metrics. From a list of 244 feature candidates, 36 candidates were selected using saliency and robustness criteria. We develop an anomaly score detector with adaptive thresholding to identify FoG events. Then, using accuracy metrics, we reduce the feature list to seven candidates. Our novel multichannel freezing index was the most selective across all window sizes, achieving sensitivity (specificity) of (). On the other hand, freezing index from the vertical axis was the best choice for a single input, achieving sensitivity (specificity) of () for ankle and () for back sensors. Our subject-independent method is not only significantly more accurate than those previously reported, but also uses a much smaller window (e.g., versus ) and/or lower tolerance (e.g., versus ).Freezing of gait (FoG) is common in Parkinsonian gait and strongly relates to falls.

    There is some evidence that functional performance and validated outcome scores differ according to the gender, age, and sport participation status of a patient after anterior cruciate ligament (ACL) reconstruction. However, the impact of these three factors, and interaction among them, has not been studied across a large relatively homogeneous group of patients to better elucidate their impact. We reviewed a large cohort of patients who had undergone ACL reconstruction to determine if ROM, knee laxity, objective performance measures, and validated outcome scores differed according to (1) gender; (2) age; and (3) sport participation status. This was a retrospective analysis of prospectively collected data. Between 2007 and 2016, we performed 3452 single-bundle ACL reconstructions in patients who participated in sport before ACL injury. Of those, complete followup (including preoperative scores and scores at 1 year after surgery; mean, 14 months; range, 12-20 months) was available on 2672 (77%) of patients. Those lost to followup and those accounted for were not different in terms of age, gender, and sports participation at baseline. The study group consisted of 1726 (65%) men and 946 (35%) women with a mean ± SD age of 28 ± 10 years. For these patients, the following measures were obtained: knee ROM (flexion and extension deficit), instrumented knee laxity, single and triple hop for distance limb symmetry index (LSI), International Knee Documentation Committee (IKDC) subjective evaluation, and Single Assessment Numeric Evaluation score. Mean scores and measures of variability were calculated for each outcome measure. Comparisons were made among gender, age, and sport status. Men had less knee laxity after reconstruction (men 1.1 ± 2.2 mm, women 1.3 ± 2.4 mm; mean difference 0.2 mm [0.1-0.4], p 45 years 90% ± 16%, mean difference: 9 [5-11], p < 0.001). Patients who had returned to their preinjury sport also scored higher and had smaller deficits for all

    2003-03-01

    To evaluate the relationship between drinking pattern and alcohol dependence severity, 209 individuals voluntarily seeking treatment for alcohol problems were administered the Alcohol Dependence Scale (ADS), the Short Alcohol Dependence Data (SADD) questionnaire, and a 12-month Timeline Follow-Back (TLFB) drinking assessment as part of their pretreatment assessment. Based on their TLFB data, participants were divided into two groups: daily (DD, n=84) and nondaily (NDD, n=125) drinkers. The two groups were compared on several demographic and drinking variables. It was hypothesized that DD would have higher scores on measures of alcohol dependence than NDD. However, the reverse pattern was found. The NDD had significantly higher ADS scores than the DD. An analysis of ADS subscale scores indicated that the primary difference between the two groups was in the domain of loss of behavior control. It is suggested that NDD may perceive intoxication as more impairing, perhaps because they have acquired less tolerance than DD. These results suggest that treatment focused on restoring a sense of behavior control would be beneficial for NDD.

    Limited data are available for advanced colorectal neoplasm in asymptomatic individuals aged 40-49 years. We aimed to identify risk factors and develop a simple prediction model for advanced colorectal neoplasm in these persons. Clinical data were collected on 2781 asymptomatic subjects aged 40-49 years who underwent colonoscopy for routine health examination. Subjects were randomly allocated to a development or validation set. Logistic regression analysis was used to determine predictors of advanced colorectal neoplasm. The prevalence of overall and advanced colorectal neoplasm was 20.2 and 2.5% respectively. Older age (45-49 years), male sex, positive serology of Helicobacter pylori, and high triglyceride and low high-density lipoprotein (HDL) levels were independently associated with an increased risk of advanced colorectal neoplasm. BMI (body mass index) was not significant in multivariable analysis. We developed a simple scoring model for advanced colorectal neoplasm (range 0-9). A cutoff of ≥4 defined 43% of subjects as high risk for advanced colorectal neoplasm (sensitivity, 79%; specificity, 58%; area under the receiver operating curve = 0.72) in the validation datasets. Older age (45-49 years), male sex, positive serology of H. pylori, high triglyceride level, and low HDL level were identified as independent risk factors for advanced colorectal neoplasm.

    Pure tone and speech audiometry are essential methods for examining the indication for hearing aids, as well as for hearing aid evaluation. Additionally, the subjective benefit of hearing aids has to be evaluated with appropriate questionnaires. The aim of the present study was to investigate the correlation between speech audiometry data and the results of a simple and user-friendly questionnaire, as well as to provide normative data for subjective benefit. Data from 136 hearing aid users with bilateral sensorineural hearing loss were analyzed retrospectively. Pure tone thresholds and Freiburg monosyllabic speech perception in the binaural situation were measured at 65 dB in quiet and in noise (signal-to-noise ratio, SNR = +5 dB), with and without hearing aids. Additionally, subjective hearing in everyday life was recorded using the 12-item Oldenburg Inventory. Improvement of speech perception with hearing aids for the Freiburg monosyllabic test in quiet was 32.0 percentage points on average; in noise, there was an average improvement of 16.4 percentage points. There was a strong correlation between the results of pure tone and speech audiometry. With hearing aids, patients scored their everyday hearing using the Oldenburg Inventory on average 1.4 scale points better than without hearing aids. Results of the Oldenburg Inventory correlate with both pure tone and speech audiometry. Hearing aid evaluation should include both speech audiometry and systematic measurement of the subjective benefit using a suitable questionnaire. In combination, the Freiburg monosyllabic test and the Oldenburg Inventory allow for quick and comprehensive evaluation.

    This study evaluated the effects of cytochrome P450 (CYP) 2D6 polymorphisms on the pharmacokinetics of controlled-release paroxetine in healthy Chinese subjects and used paroxetine as a tool drug to compare the performance of traditional phenotype and activity score systems. Pharmacokinetic data were evaluated in 24 subjects who received a single oral dose of 25 mg controlled-release paroxetine. Plasma paroxetine concentrations were measured by LC-MS/MS. CYP2D6 genotypes were tested by PCR and direct DNA sequencing. Subjects were classified by two systems of phenotype prediction. In the traditional phenotype system, subjects were classified as extensive metabolizers or intermediate metabolizers; in the activity score system, subjects were divided into four activity groups. Analysis of variance testing was applied to estimate the effects of CYP2D6 polymorphisms on the pharmacokinetics of paroxetine. With the traditional phenotype system, significant differences were observed in the following pharmacokinetic parameters of paroxetine: t 1/2, C max, AUC0-t, AUC0-inf, Vz/F, and CL/F (all P paroxetine was about 3.5-fold higher in the intermediate metabolizer group than in the extensive metabolizer group. With the activity score system, significant differences were observed in the t 1/2, C max, AUC0-t, AUC0-inf, Vz/F, and CL/F among the four different activity score groups (all P paroxetine decreased by around one half as the activity score increased by 0.5. The pharmacokinetics of controlled-release paroxetine after a single administration was affected by CYP2D6 polymorphisms. Both the traditional phenotype and the activity score systems performed well and distinguished subjects with different drug exposures. The activity score system provided a more detailed classification for the subjects.

    Shoulder arthroplasty (SA) has been performed by many years for the treatment of several conditions, including osteoarthritis and proximal humeral fractures following trauma. Surgical site infection (SSI) following Shoulder arthroplasty remains a challenge, contributing to increased morbidity and costs. Identification of risk factors may help implementing adequate strategies to prevent infection. We aimed to identify pre- and intra-operative risk factors associated with deep infections after Shoulder arthroplasty. An unmatched case-control study was conducted to describe the prevalence, clinical and microbiological findings, and to evaluate patient and surgical risk factors for prosthetic shoulder infection (PSI), among 158 patients who underwent SA due to any reason, at a tertiary public university institution. Risk factors for PSI was assessed by uni- and multivariate analyses using multiple logistic regression. 168 SA from 158 patients were analyzed, with an overall infection rate of 9.5% (16/168 cases). Subjects undergoing SA with American Society of Anesthesiologists (ASA) grade III or higher (odds ratio [OR]=5.30, 95% confidence interval [CI]=1.58-17.79, p<0.013) and presenting local hematoma after surgery (odds ratio [OR]=7.10, 95% confidence interval [CI]=1.09-46.09, p=0.04) had higher risk for PSI on univariate analysis. However, only ASA score grade III or higher remained significant on multivariate analysis (OR=4.74, 95% CI=1.33-16.92, p=0.016). Gram-positive cocci and Gram-negative bacilli were equally isolated in 50% of cases; however, the most commonly detected bacterium was Pseudomonas aeruginosa (18.7%). This study provides evidence suggesting that patient-related known factors such as higher ASA score predisposes to shoulder arthroplasty-associated infection. Furthermore, unusual pathogens associated with PSI were identified. Copyright © 2017 Sociedade Brasileira de Infectologia. Published by Elsevier Editora Ltda. All rights reserved.

    Framingham risk score (FRS) is a widely used tool to identify asymptomatic individuals who are at risk to cardiovascular disease. We aimed to investigate the association between subclinical atherosclerosis and FRS among elderly with both type 2 diabetes mellitus and healthy participants. Methods: As case-control study was done on 58 men and women, who had type 2 diabetes mellitus, and in 59 age and gender matched control participants. They were selected from a geriatric outpatient clinic at Ain Shams University Hospital, Cairo, Egypt. The carotid intima-media thickness (cIMT), clinical variables, plasma lipid profile, high-sensitivity C-reactive protein (hs-CRP) were measured for each participants. Results: Diabetic patients had higher FRS, body mass index (BMI), fasting glucose, total cholesterol level, and LDL levels than control subjects. Mean cIMT values were higher in diabetic than healthy subjects. After multivariate regression analysis, FRS was independently associated with carotid IMT in type 2 diabetes patients after adjustment for other risk factors. However triglycerides and BMI were independently associated with cIMT among the control group. Conclusion: FRS is likely to be more informative about the atherosclerotic state in diabetics but not in the healthy elderly. PMID:24551481

    There is no method to be used as a reference standard for nutritional assessment. This study aims to develop and verify the performance of a new tool, based on the Item Response Theory (IRT), from the Subjective Global Assessment (SGA) questionnaire, in hospitalized adult patients. Retrospective cohort study, composed by secondary database, formed by patients included from October 2005 to June 2006. The new tool presented was developed through the usage of cumulative models from the IRT. Out of 1503 evaluated patients, 2/3 were randomly selected to the development sample of the new tool and 1/3 to the performance verification sample. After item adjustments, the "Nutritional Assessment Score" (NAS) was proposed, with reduced number of questions, and, in comparison to SGA, less polytomic items. NAS demonstrates association to variables that are clinically relevant (hospital mortality, long hospital stay, serum albumin and body mass index) and has shown itself to be more precise to patients with the worst degrees of nutritional status. Results point to the validation of the NAS in detecting, accurately, the nutritional status of hospitalized patients.

    Introduction The aim of this study was to investigate the magnetic resonance imaging (MRI) features of bone disease in the arthritis mutilans (AM) form of psoriatic arthritis (PsA). Methods Twenty-eight patients with erosive PsA were enrolled (median disease duration of 14 years). Using x-rays of both hands and feet, 11 patients were classified as AM and 17 as non-AM (erosive psoriatic arthritis without bone lysis)by two observers. MRI scans (1.5T) of the dominant hand (wrist and fingers scanned separately) were obtained using standard contrast-enhanced T1-weighted and fat-saturated T2-weighted sequences. Scans were scored separately by two readers for bone erosion, oedema and proliferation using a PsA MRI scoring system. X-rays were scored for erosions and joint space narrowing. Results On MRI, 1013 bones were scored by both readers. Reliability for scoring erosions and bone oedema was high (intraclass correlation coefficients = 0.80 and 0.77 respectively) but only fair for bone proliferation (intraclass correlation coefficient = 0.42). MRI erosion scores were higher in AM patients (53.0 versus 15.0, p = 0.004) as were bone oedema and proliferation scores (14.7 versus 10.0, p = 0.056 and 3.6 versus 0.7, p = 0.003 respectively). MRI bone oedema scores correlated with MRI erosion scores and X-ray erosion and joint space narrowing scores (r = 0.65, p = 0.0002 for all) but not the disease activity score 28-C reactive protein (DAS28CRP) or pain scores. Conclusions In this patient group with PsA, MRI bone oedema, erosion and proliferation were all more severe in the AM-form. Bone oedema scores did not correlate with disease activity measures but were closely associated with X-ray joint damage scores. These results suggest that MRI bone oedema may be a pre-erosive feature and that bone damage may not be coupled with joint inflammation in PsA. PMID:19126234

    To examine levels of fluorosis among children in two Canadian communities exposed to fluoride. One community had discontinued fluoride, the other had maintained it. Water supplies, however, were fluoridated for all the children when their esthetically important teeth were mineralized. We examined 8,277 children to assess Thystrup-Fejerskov Index (TFI) scores. Multivariate Poisson regression models were used to identify the relationship between TFI and water fluoride status, age, gender, SES, and dietary and fluoride exposure histories (supplements, rinses, toothpaste amount, tooth brushing frequency, and tooth brushing starting age). Parent(s) completed questionnaires. Overall, levels of fluorosis were low to mild, with residents of the fluoridation-ended communities having marginally higher TFI scores than those of the still-fluoridated community. Females had higher TFI scores than males. Children aged 10 years or more had higher TFI scores than younger children. Consuming bottled water between birth and 6 months of age was protective. Exposure to fluoridation technologies was consistently associated with fluorosis experience. Children who began brushing with fluoride toothpaste between their first and second birthdays had higher TFI scores than those who began between their second and third birthdays, regardless of daily brushing frequency. Children who regularly used supplements had higher TFI scores than those who did not. Children with a college-educated father had higher TFI scores than those whose fathers had less education. Higher fluoride exposure slightly increased the likelihood that a child had a higher TFI score, especially when more fluoridation technologies were used at home. Copyright 2003 S. Karger AG, Basel

    Full Text Available Background: In the present study, we explored the associations between hypomania, symptoms of depression, sleep complaints, physical activity and mental toughness. The latter construct has gained interest for its association with a broad variety of favorable behavior in both clinical and non-clinical samples.Subjects and Methods: The non-clinical sample consisted of 206 young adults (M = 21.3 years; age range: 18–24 years; 57.3% males. They completed questionnaires covering hypomania, mental toughness, symptoms of depression, physical activity, and sleep quality.Results: Higher hypomania scores were associated with higher mental toughness, increased physical activity, lower symptoms of depression and lower sleep complaints. No gender differences were observed. Higher hypomania scores were predicted by higher scores of mental toughness subscales of control and challenge, and physical activity.Conclusion: The pattern of results suggests that among a non-clinical sample of young adults, self-rated hypomania scores were associated with higher scores on mental toughness and physical activity, along with lower depression and sleep complaints. The pattern of results further suggests that hypomania traits are associated with a broad range of favorable psychological, behavioral and sleep-related traits, at least among a non-clinical sample of young adults.

    Nowadays, measuring score in the form of subjective questionnaires is the important tool for clinical evaluation of the foot and ankle-related problems. VisualAnalogue Scale-Foot and Ankle (VAS-FA) is the newly developed subjective questionnaire, which has sufficiency of validity and reliability from a previous study Translate the original English version of VAS-FA into the Thai version and evaluate the validity and reliability of Thai VAS-FA in patients with foot and ankle-related problems. According to the forward-backward translation protocol, original VAS-FA was translated into the Thai version. Thai VAS-FA and validated Thai Short Form-36 (SF-36) questionnaires were distributed to 42 Thai patients to complete. For validation, Thai VAS-FA scores were correlated with SF-36 scores. For reliability, the test-retest reliability and internal consistency were analyzed. Thai VAS-FA score demonstrated the sufficient correlations with physical functioning (PF), role physical (RP), bodily pain (BP) domains, and total score of SF-36 (statistically significant with p 0.5 values). The result of reliability revealed highly intra-class correlation coefficient as 0.995 from test-retest study. The internal consistency was excellent with Cronbach alpha: 0.995. The original VAS-FA score is a well-validated, subjective, visual-analogue-scale based outcome score. The Thai version of VAS-FA form maintained the validity and reliability of the original version. This newly translated-validated score can be distributed for the evaluation of the functions, symptoms, and limitation of activities in Thai patients with foot and ankle problems.

    Humor research has focused on relationships between humor and various personality traits. As personality and morningness-eveningness, as well as personality and humor, are related based on genetics and neurobehavioral function, one might also expect a relationship between humor and chronotype. 197 students responded to the Composite Scale of Morningness as a measure of chronotype, the Sense of Humor Questionnaire and a 10-item version of the Big Five Inventory. Individuals scoring as evening types reported a greater sense of humor than morning individuals, with higher morningness scores. In a stepwise linear regression, Extraversion, Agreeableness, Openness, and Chronotype each accounted for a significant amount of variance in sense of Humor scores. That is, the relationship between scores on Sense of Humor and evening orientation was significant after controlling for personality dimensions. Eveningness was related to sense of Humor scores in women but not in men. Social but not cognitive humor was predicted by eveningness.

    To assess the relationship between 25-hydroxyvitamin D [25(OH)D] blood concentrations in subjects with obesity and type 2 diabetes mellitus (T2D) risk according to the Finnish Diabetes Risk Score (FINDRISC) modified for Latin America (LA-FINDRISC). This study was conducted in Ciudad Bolívar, Venezuela. Eighty two women and 20 men (53 obese and 49 nonobese), with an average age of 42.6±12.30 years were enrolled. Weight, height, body mass index (BMI), waist circumference (WC), fasting glucose, basal insulin, plasma lipids, Homeostasis Model Assessment-Insulin Resistance (HOMA-IR), and 25(OH)D levels were measured. FINDRISC with WC cutoff points modified for Latin America was applied. No difference in 25(OH)D levels between obese and nonobese subjects was found. When anthropometric, clinical, and biochemical variables according to the 25(OH)D status were compared, the only difference detected was higher LA-FINDRISC in the insufficient/low 25(OH)D group compared to normal 25(OH)D levels group (12.75±6.62; vs 10.15±5.21; p=0.031). LA-FINDRISC was negatively correlated with plasma 25(OH)D levels (r=-0.302; p=0.002) and positively correlated with the HOMA-IR index (r=0.637; p=0.0001). The LA-FINDRISC significantly correlated with both 25(OH)D levels and insulin resistance markers in this group of patients. Copyright © 2016 Primary Care Diabetes Europe. Published by Elsevier Ltd.

    Full Text Available Background: Malnutrition has been associated with poor health outcomes in hospitalized patients. This study assessed the validity of the scored patient-generated subjective global assessment (PG-SGA in adult patients who had undergone an open appendectomy, and examined the association of this assessment tool with length of hospital stay. Methods: Nutritional status was determined by using the scored PG-SGA in adult patients (n = 86 who had undergone an open appendectomy within 24 hours of admission. Variables were compared between well-nourished and malnourished participants. Regression analysis was used to identify potential predictors for length of hospital stay. Receiver operator characteristic (ROC analysis was used to examine the validity of the PG-SGA score to predict the nutritional status. Results: On admission, 17% of the study subjects were malnourished and associated with a significantly older age (53.0 vs. 39.5, greater PG-SGA score (8 vs. 2, higher comorbidity (67% vs. 27%, and longer length of hospital stay (6.9 d vs. 4.1 d. The PG-SGA score and comorbidity were the determined risk factors for length of hospital stay after performing multiple regression analysis. Furthermore, the PG-SGA score had a significantly positive correlation with length of hospital stay (Spearman's rho = 0.378, p < 0.001. The area under the ROC curve indicating the PG-SGA score, compared with nutritional status, is 0.9751. Conclusions: The scored PG-SGA in adults receiving an appendectomy is significantly associated with length of hospital stay, and is an effective tool for assessing the nutritional status of patients with cancer and chronic illness, as well as of patients with acute surgical abdomen.

    As proteins evolve, amino acid positions key to protein structure or function are subject to mutational constraints. These positions can be detected by analyzing sequence families for amino acid conservation or for coevolution between pairs of positions. Coevolutionary scores are usually rank-ordered and thresholded to reveal the top pairwise scores, but they also can be treated as weighted networks. Here, we used network analyses to bypass a major complication of coevolution studies: For a given sequence alignment, alternative algorithms usually identify different, top pairwise scores. We reconciled results from five commonly-used, mathematically divergent algorithms (ELSC, McBASC, OMES, SCA, and ZNMI), using the LacI/GalR and 1,6-bisphosphate aldolase protein families as models. Calculations used unthresholded coevolution scores from which column-specific properties such as sequence entropy and random noise were subtracted; "central" positions were identified by calculating various network centrality scores. When compared among algorithms, network centrality methods, particularly eigenvector centrality, showed markedly better agreement than comparisons of the top pairwise scores. Positions with large centrality scores occurred at key structural locations and/or were functionally sensitive to mutations. Further, the top central positions often differed from those with top pairwise coevolution scores: instead of a few strong scores, central positions often had multiple, moderate scores. We conclude that eigenvector centrality calculations reveal a robust evolutionary pattern of constraints-detectable by divergent algorithms--that occur at key protein locations. Finally, we discuss the fact that multiple patterns coexist in evolutionary data that, together, give rise to emergent protein functions. © 2015 Wiley Periodicals, Inc.

    Full Text Available Recent literature has presented evidence that cardiovascular risk factors (CVRF play an important role on cognitive performance in elderly individuals, both those who are asymptomatic and those who suffer from symptoms of neurodegenerative disorders. Findings from studies applying neuroimaging methods have increasingly reinforced such notion. Studies addressing the impact of CVRF on brain anatomy changes have gained increasing importance, as recent papers have reported gray matter loss predominantly in regions traditionally affected in Alzheimer’s disease (AD and vascular dementia in the presence of a high degree of cardiovascular risk. In the present paper, we explore the association between CVRF and brain changes using pattern recognition techniques applied to structural MRI and the Framingham score (a composite measure of cardiovascular risk largely used in epidemiological studies in a sample of healthy elderly individuals. We aim to answer the following questions: Is it possible to decode (i.e., to learn information regarding cardiovascular risk from structural brain images enabling individual predictions? Among clinical measures comprising the Framingham score, are there particular risk factors that stand as more predictable from patterns of brain changes? Our main findings are threefold: i we verified that structural changes in spatially distributed patterns in the brain enable statistically significant prediction of Framingham scores. This result is still significant when controlling for the presence of the APOE 4 allele (an important genetic risk factor for both AD and cardiovascular disease. ii When considering each risk factor singly, we found different levels of correlation between real and predicted factors; however, single factors were not significantly predictable from brain images when considering APOE4 allele presence as covariate. iii We found important gender differences, and the possible causes of that finding are discussed.

    Atherosclerosis disease is a leading cause for mortality and morbidity. The narrowing/rupture of a vulnerable atherosclerotic plaque is accountable for acute cardiovascular events. However, despite of an intensive research, a reliable clinical method which may disclose a vulnerable patient is still unavailable. We tested the association of ADAM17 (A Disintegrin and Metallo Protease Domain 17) circulating substrates (sICAM-1, sVCAM-1, sIL6R and sTNFR1) with a second major cardiovascular events [MACEs] (cardiovascular death, peripheral artery surgeries, non-fatal myocardial infarction and non-fatal stroke) in 298 patients belonging to the Vascular Diabetes (AVD) study. To evaluate ADAM17 activity we create ADAM17 score through a RECPAM model. Finally we tested the discrimination ability and the reclassification of clinical models. At follow-up (mean 47 months, range 1-118 months), 55 MACEs occurred (14 nonfatal MI, 14 nonfatal strokes, 17 peripheral artery procedures and 10 cardiovascular deaths) (incidence = 7.8% person-years). An increased risk for incident events was observed among the high ADAM17 score individuals both in univariable (HR 19.20, 95% CI 15.82-63.36, p atherosclerosis. Copyright © 2015 Elsevier Ireland Ltd.

    This study was undertaken to assess stroke awareness of the Estonian population. Investigators were asked to fill in an original, closed-ended multiple-choice questionnaire about the definition, risk factors, symptoms and behavior at the onset of stroke by randomly selected subjects in public places of the two biggest cities in Estonia (Tallinn and Tartu). The study included 355 persons. Most of the respondents knew that stroke is an acute disease and that one should call the ambulance at the onset of a stroke. Speech disorder and paresis were the best known symptoms, while hypertension was the best known risk factor. There were no differences between the sexes, but advanced age and higher level of education were related to higher awareness. The overall knowledge was better compared to many other studies. Future awareness campaigns should be addressed to younger subjects with lower education. Copyright © 2012 S. Karger AG, Basel.

    The American Board of Surgery In-Training Exam (ABSITE) is administered to all general surgery residents annually. Given the recent changes in the format of the examination and in the material being tested, it has become increasingly difficult for residents to prepare for the ABSITE. This is especially true for incoming postgraduate year (PGY) 1 residents because of the respective variability of the surgical clerkship experience. There have been many studies in the past that support the use of weekly assigned readings and examinations to improve ABSITE scores. Other studies have investigated the study habits of residents to determine those that would correlate with higher ABSITE scores. However, there is a lack of information on whether completing review questions plays an integral role in preparing for the ABSITE. We hypothesize that those residents who completed more review questions performed better on the ABSITE. ABSITE scores of current and past general surgery residents at SUNY Downstate Medical Center, a university hospital, were reviewed (2009-2013). These residents were then polled to determine how they prepared for their first in-training examination. Average ABSITE percentile was 46.4. Mean number of review questions completed by residents was 516.7. Regression analysis showed that completion of more review questions was associated with a significantly higher percentile score on the ABSITE (p < 0.0027). Further analysis showed that for every 100 review questions completed by a PGY 1 resident taking the ABSITE for the first time, the ABSITE percentile score should improve by 3.117 ± 0.969. Average reported study time in hours/week was 9.26. Increased study time was also significantly correlated with higher ABSITE percentile scores (p < 0.007). Again, further analysis showed that for every 1h/wk spent studying, ABSITE percentile score should increase by 1.76 ± 0.62. The Kruskal-Wallis H test showed that studying in group vs individual settings had no

    Bilingualism may protect against cognitive aging and delay the onset of dementia. However, studies comparing monolinguals and bilinguals on such metrics have produced inconsistent results complicated by confounding variables and methodological concerns. We addressed this issue by comparing cognitive performance in a more culturally homogeneous cohort of older Spanish-speaking monolingual (n = 289) and Spanish-English bilingual (n = 339) Mexican-American immigrants from the Sacramento Longitudinal Study on Aging. After adjusting for demographic differences and depressive symptoms, both groups performed similarly at baseline on verbal memory but the bilingual group performed significantly better than the monolingual group on a cognitive screening test, the Modified Mini-Mental State Examination (3MS; p bilingual group, neither language of testing nor degree of bilingualism was significantly associated with 3MS or verbal memory scores. Amongst individuals who performed in the normal or better range on both tests at baseline and were followed for an average of 6 years, both monolinguals and bilinguals exhibited similar rates of cognitive decline on both measures. These findings suggest that bilingualism is associated with modest benefits in cognitive screening performance in older individuals in cross-sectional analyses that persist across longitudinal analyses. The effects of bilingualism should be considered when cognitively screening is performed in aging immigrant populations.

    Subjects with lower limb amputation develop new motor control strategies to preserve balance when they experience unexpected perturbations. Most studies performed thus far have not aimed to discuss the possible differences in postural control between subjects with vascular unilateral transtibial amputation (UTA) and subjects with traumatic UTA. To analyze the automatic postural reaction in response to unexpected surface perturbations in a sample of subjects with traumatic and vascular UTA and to compare these observations with those for a group of healthy subjects. University department. Observational study. A total of 9 men with traumatic UTA, 7 men with vascular UTA, and 10 control subjects without amputation. Computerized dynamic posturography Smart EquiTest System version 8.0 was used to measure automatic postural responses in both groups. The motor control test was used to assess the participants' automatic postural responses to unexpected surface perturbations. Latency scores showed that subjects with traumatic UTA coped with faster latencies under their sound limb than did the subjects with vascular UTA in medium backward and forward perturbations (medium-backward: P = .004; medium-forward: P = .037). In addition, the subjects with traumatic UTA also managed faster responses to medium-backward (P = .017 versus right control limb; P = .046 versus left control limb) and large-backward (P = .021 versus right control limb) and medium-forward (P = .012 versus right control limb; P = .043 versus left control limb) perturbations in their sound limb in contrast to control subjects. Weight symmetry showed that the subjects with traumatic UTA bore significantly more weight through their sound limb compared with the control subjects during medium and large backward translations (P = .028 and P = .045, respectively). The subjects with traumatic UTA had a greater reliance on their sound limb, and they had faster latencies and more weight in the sound limb upon

Methods: This paper assessed a part of Basic Health Research (Riskesdas 2007 data. For this assessment, subjects 15 years old or more had their visual acuity measured using the Snellen chart and their mental health status determined using the Self Reporting Questionnaire (SRQ 20. A subject was considered to have probable MED if the subject had a total score of 6 or more on the SRQ. Based on the measure of visual acuity, visual acuity was divided into 3 categories: normal/mild (20/20 to 20/60; low vision (less than 20/60 to 3/60; and blind (less than 3/60 to 0/0. Results: Among 972,989 subjects, 554,886 were aged 15 years or older. 11.4% of the subjects had probable MED. The prevalence of low vision and blindness was 5.1% and 0.9%, respectively. Compared to subjects with normal or mild visual impairments, subjects with low vision had a 74% increased risk for probable MED [adjusted relative risk (RRa=1,75; 95% confidence interval (CI=1,71-1,79].  Blind subjects had a 2.7-fold risk to be probable MED (RRa=2.69; 95% CI=2.60-2.78] compared to subjects with normal or mild visual impairments. Conclusion: Visual impairment severity increased probable MED risk. Therefore, visual impairment subjects need more attention on probable MED. (Health Science Indones 2011;2:9-13

    The heritability of chronic obstructive pulmonary disease (COPD) cannot be fully explained by recognized genetic risk factors identified as achieving genome-wide significance. In addition, the combined contribution of genetic variation to COPD risk has not been fully explored. We sought to determine: (1) whether studies of variants from previous studies of COPD or lung function in a larger sample could identify additional associated variants, particularly for severe COPD; and (2) the impact of genetic risk scores on COPD. We genotyped 3,346 single-nucleotide polymorphisms (SNPs) in 2,588 cases (1,803 severe COPD) and 1,782 control subjects from four cohorts, and performed association testing with COPD, combining these results with existing genotyping data from 6,633 cases (3,497 severe COPD) and 5,704 control subjects. In addition, we developed genetic risk scores from SNPs associated with lung function and COPD and tested their discriminatory power for COPD-related measures. We identified significant associations between SNPs near PPIC (P = 1.28 × 10-8) and PPP4R4/SERPINA1 (P = 1.01 × 10-8) and severe COPD; the latter association may be driven by recognized variants in SERPINA1. Genetic risk scores based on SNPs previously associated with COPD and lung function had a modest ability to discriminate COPD (area under the curve, ∼0.6), and accounted for a mean 0.9-1.9% lower forced expiratory volume in 1 second percent predicted for each additional risk allele. In a large genetic association analysis, we identified associations with severe COPD near PPIC and SERPINA1. A risk score based on combining genetic variants had modest, but significant, effects on risk of COPD and lung function.

    This pilot study was designed to investigate the relationship between chiropractic students' learning and study strategies and academic performance. Differences in strategic learning between chiropractic students with higher grade points averages (GPAs) and those with lower GPAs have not been previously reported. Fifty-seven consenting first-trimester chiropractic students self-administered the Learning and Study Strategies Inventory (LASSI). Differences between high and low GPA groups were evaluated for 10 subtests and three factors using independent samples t-tests. The high GPA group scored significantly higher (p Attitude, Concentration, Motivation, Test Strategies, and Selecting Main Ideas, and on factors Effort-Related Activities and Goal Orientation. No differences between groups were found for subtests Information Processing, Self-Testing, Study Aids, and Time Management or for the Cognitive Activities factor. The results of this study show that differences in LASSI subtest and factor scores are associated with academic performance. For the participants studied, motivational and affective aspects of strategic learning contributed to higher academic performance, whereas cognitive strategies did not. Higher performing students utilized Effort-Related and Goal Orientation learning strategies at significantly higher levels than lower performing students. The LASSI may be useful in identifying students who could benefit from learning and study skills development. Longitudinal study is recommended to investigate the effects of students' learning and study strategies on different academic content domains as well as the effects of strategic study and learning skills training on academic performance.

    Full Text Available This article considers higher education in the context of global knowledge economy policies as a site for the production of economic subjectivities. Drawing insights from poststructuralist theory and feminist economics, it explores how the incorporation of economic discourse and market metaphors into education policy and practice functions as a disciplinary technique of governmentality. The article argues that while economic discourse displaces, disciplines and disrupts educational discourse, there is a need for greater acknowledgement of the productive potential of the intersection of education and economy as a means through which agency is in part accomplished. Implications for university learning and labour are considered, with a view to contributing to dialogues about new ways of undisciplining economic subjectivities, through which new ways of doing and being might enact alternative educational economies.

A descriptive, cross sectional study among outpatient medical clinics, in The AIDS Support Organization (TASO), Mulago Centre, Kampala, Uganda. The study group (n=217) consisted of male (n=60) and female (n=157) HIV patients (18-67 years). Purposive sampling was used. Anthropometry (weight, height, BMI), nutritional history (body weight, dietary intake, gastrointestinal symptoms, functional capacity and infections), and clinical status were assessed. Sensitivity and specificity of PG-SGA were determined using Receiver Operating Characteristic (ROC) curve. Data collection was done from April-May 2008. Only 12% of the subjects were underweight and over half (58.2%) had normal weight. The PG-SGA had low sensitivity (69.2%) and specificity (57.1%) at categorizing the risk for malnutrition indicated by BMInutritional status in this population.

  7. The Impact of Relative Poverty on Norwegian Adolescents’ Subjective Health: A Causal Analysis with Propensity Score Matching

    Jon Ivar Elstad

    2012-12-01

    Full Text Available Studies have revealed that relative poverty is associated with ill health, but the interpretations of this correlation vary. This article asks whether relative poverty among Norwegian adolescents is causally related to poor subjective health, i.e., self-reported somatic and mental symptoms. Data consist of interview responses from a sample of adolescents (N = 510 and their parents, combined with register data on the family’s economic situation. Relatively poor adolescents had significantly worse subjective health than non-poor adolescents. Relatively poor adolescents also experienced many other social disadvantages, such as parental unemployment and parental ill health. Comparisons between the relatively poor and the non-poor adolescents, using propensity score matching, indicated a negative impact of relative poverty on the subjective health among those adolescents who lived in families with relatively few economic resources. The results suggest that there is a causal component in the association between relative poverty and the symptom burden of disadvantaged adolescents. Relative poverty is only one of many determinants of adolescents’ subjective health, but its role should be acknowledged when policies for promoting adolescent health are designed.

    This study was undertaken to assess any impact on National Board of Medical Examiners (NBME) neurology and psychiatry subject examination scores of changing from an integrated neuropsychiatry clerkship to independent neurology and psychiatry clerkships. NBME psychiatry and neurology subject examinations scores were compared for all 625 students completing the required neuropsychiatry clerkship in academic years 2005-2006 through 2008-2009 with all 650 students completing the independent neurology and psychiatry clerkships in academic years 2009-2010 through 2012-2013. Statistical adjustments were made to ensure comparability across groups and over time. A significant improvement in subject examination scores was associated with the independent clerkships. The independent clerkship model was associated with a modest improvement in NBME subject examination scores. This finding may be attributable to many causes or combination of causes other than curricular design. Curricular planners need to pay attention to the potential impact of course integration on specialty-specific NBME subject examination performance.

Students' overall explanations suggest that discussing with peers and applying knowledge in pathophysiology cases underlies this association. Discussion with well-prepared peers during seminars improves student perceptions of deeper learning and peer-instructed seminar attendance was associated with higher exam scores.

    Previous studies on semantic priming have suggested that schizophrenic patients with language disturbances demonstrate enhanced semantic and indirect semantic priming effects relative to controls. However, the interpretation of semantic priming studies in schizophrenic patients is obscured by methological problems and several artefacts (such as length of illness). We, therefore, used a psychometric high-risk approach to test whether healthy subjects reporting language disturbances resembling those of schizophrenics (as measured by the Frankfurt Complaint Questionnaire subscale 'language') display increased priming effects. In addition, the Schizotypal Personality Questionnaire was used to cover symptoms of schizotypal personality. Enhanced priming was expected to occur under conditions favouring automatic processes. One hundred and sixty healthy subjects performed a lexical decision semantic priming task containing two different stimulus onset asynchronicities (200 ms and 700 ms) with two experimental conditions (semantic priming and indirect semantic priming) each. Analyses of variance revealed that the Frankfurt Complaint Questionnaire-' language' high scorers significantly differed from low scorers in three of the four priming conditions indicating increased automatic spreading activation. No significant results were obtained for the Schizotypal Personality Questionnaire total and subscales scores. In line with Maher and Spitzer it is suggested that increased automatic spreading activation underlies schizophrenia-typical language disturbances which in our study cannot be attributed to confounding variables such as different reaction time baselines, medication or length of illness. Finally, results confirm that the psychometric high-risk approach is an important tool for investigating issues relevant to schizophrenia.

    Full Text Available In this paper, I claim that subjectivity is a way of being that is constituted through a set of practices in which the self is subject to the dangers of fictionalizing and plotting her life and self-image. I examine some ways of becoming subject through narratives and through theatrical performance before others. Through these practices, a real and active subjectivity is revealed, capable of self-knowledge and self-transformation.

    To assess the effect of postprandial lipemia on endothelial function, insulin resistance, and lipid profile in healthy subjects. A prospective', interventional study in 14 healthy young men aged 18-25 years who were given a high-fat meal. Endothelial function was measured using flow-mediated dilation (FMD) in the brachial artery, flow velocity, mean arterial pressure and serum nitrite/nitrate levels (NO(2)/NO(3)). Glucose, insulin, total cholesterol, and triglyceride levels were also tested. Insulin resistance was determined by calculating the HOMA-IR index (Homeostatic Model Assessment-Insulin Resistance). Baseline FMD was 5.9 ± 1.1%. Postprandial lipemia reduced endothelial function by approximately 50% in the first (3.3 ± 0.5%, p=0.03) and second (3.3 ± 0.4%, p=0.04) moment respectively. This finding was associated to an increased flow rate in the brachial artery and lower NO(2)/NO(3) levels (plipemia causes changes in circulating lipid profile and induces endothelial dysfunction and higher insulin resistance.

    To develop diabetes risk score (RS) based on the current definition of diabetes, we retrospectively analyzed consecutive 4,159 health examinees who were non-diabetic at baseline. Diabetes, diagnosed by fasting plasma glucose (FPG) ≥7.0 mmol/L, 2hPG ≥11.1 mmol/L and/or HbA1c ≥6.5% (48 mmol/mol), developed in 279 of them during the mean period of 4.9 years. A full RS (RS Full ), a RS without 2hPG (RS -2hPG ) and a non-invasive RS (RS NI ) were created on the basis of multivariate Cox proportional model by weighted grading based on hazard ratio in half the persons assigned. The RSs were verified in the remaining half of the participants. Positive family history (FH), male sex, smoking and higher age, systolic blood pressure (SBP), FPG, 2hPG and HbA1c were independent predictors for RS Full . For RS -2hPG , 7 independent predictors, exclusive of 2hPG and smoking but inclusive of elevated triglycerides (TG) comparing to RS Full , were selected. FH, male sex, and higher age, SBP and HbA1c were independent predictors in RS NI . In the validation cohort, C-statistic (95%CI) of RS Full , RS -2hPG and RS NI were 0.80 (0.76-0.84), 0.75 (0.70-0.78) and 0.68 (0.63-0.72), respectively, which were significantly different from each other (P <0.01). Absolute percentage difference between predicted probability and observed diabetes were 1.9%, 0.7% and 0.9%, by the three scores, respectively, and not significantly different from each other. In conclusion, diabetes defined by the current criteria was predicted by the new diabetes risk scores with reasonable accuracy. Nonetheless, RS Full with a postchallenge glucose value performed superior to RS -2hPG and RS NI .

    To evaluate the inter-examiner reproducibility of Ocular Response Analyzer (ORA) parameters in healthy subjects using the waveform score (WS) for quality control of acquisition. Fifteen healthy subjects had their intraocular pressure (IOP) measured with ORA by 2 masked examiners. An acquisition protocol that aimed at obtaining 4 reliable measurements in each eye with WS≥6 and with as few repeated measurements as possible was employed, whereas a maximum of 8 measurements per eye was allowed. Additional good quality criteria included symmetrical force-in and force-out applanation signal peaks on the ORA waveform and few or no distortions of the applanation signal curve. Only the right eyes were included in the analysis. Examiners were trained but not experienced. The inter-examiner reproducibility of ORA parameters was assessed using the intraclass correlation coefficient (ICC). Mean values of the best 4 measurements were considered in analysis. ICC including the best 4 measurements per eye was high for all ORA parameters. Specifically, ICC for Goldmann-correlated IOP was 0.961, for corneal-compensated IOP was 0.962, for corneal resistance factor was 0.987, and for corneal hysteresis was 0.988. Similar reproducibility was found when only the 3 best measurements per eye were included in the analysis. The protocol for IOP measurement with ORA using the WS ≥6 as quality index achieved high inter-examiner reproducibility for all ORA parameters. High reproducibility was obtained even by inexperienced examiners when considering the mean of the best 3 measurements per eye.

    The aim of the present study was to assess the cross-cultural adaptation and reliability and validity of the Oral Aesthetic Subjective Impact Score (OASIS) for the perception of oral aesthetics in Brazilian adolescents. The cross-cultural adaptation was developed in agreement with internationally recommended methodology. The psychometric properties were assessed by application of the Brazilian version of the OASIS in 304 adolescents aged 13 to 19 years who were enrolled at two public schools and one private school in Tubarão, Brazil. The internal consistency of the instrument was measured using Cronbach's alpha. The reliability was estimated through stability and homogeneity, using the Intraclass Correlation Coefficient and the Bland-Altman agreement. Validity was determined by comparing the OASIS-Brazil with the aesthetic component of the instrument Oral Impact on Daily Performance (OIDP) using the Spearman Rank Correlation Coefficient. The internal consistency obtained was 0.52. Inter-observer and intra-observer correlations were strong, 0.87 and 0.83, respectively. The correlation with the aesthetic part of OIDP was 0.44. The results showed that the process of cross-cultural adaptation was successful and the adapted instrument showed good psychometric properties.

    The scored Patient-Generated Subjective Global Assessment tool (PG-SGA), regarded as the most appropriate means of identifying malnutrition in cancer patients, is often challenging to implement in a busy outpatient setting. We assessed the validity of an abridged version of the PG-SGA (abPG-SGA), which forgoes the physical examination, and compared its usefulness in discerning malnutrition to the full PG-SGA and Malnutrition Screening Tool (MST). The nutritional status of 90 oncology outpatients receiving chemotherapy was assessed according to SGA global rating, PG-SGA, and MST. Receiver operating characteristic (ROC) curves were generated to estimate the sensitivity and specificity of various cut-off scores for malnutrition. Thirty-six percent of patients were malnourished (SGA). The abPG-SGA yielded 94% sensitivity and 78% specificity and area under the curve (AUC) = 0.956, which was slightly lower than PG-SGA (97% sensitivity, 86% specificity, AUC = 0.967) and higher than MST (81% sensitivity, 72% specificity, AUC = 0.823). Patient reported symptoms included loss of appetite (30%), altered taste (31%), fatigue (30%), and decreased ability to perform activities of daily living (53%). In conclusion, the abPG-SGA is a practical, informative and valid tool for detecting malnutrition in the outpatient oncology setting.

    Burnout syndrome is common in healthcare workers. We evaluated its prevalence in paediatric residents and investigated its influence on cerebral function correlations, using functional magnetic resonance imaging (MRI), when they carried out an attentional paradigm. This cross-sectional descriptive study involved 28 residents from the Department of Paediatrics at the University of São Paulo. The functional MRI was carried out while the residents completed the Stroop colour word task paradigm to investigate their attentional task performance. The Maslach Burnout Inventory (MBI) was applied, and stress was assessed using the Lipp Inventory of Stress Symptoms for Adults and by a visual analogue mood scale. The MBI subscales of depersonalisation and emotional exhaustion indicated that 53.1% of the residents had moderate or high burnout syndrome. The whole-brain multivariate analysis showed positive correlations between the blood oxygenation level dependent effect and the MBI depersonalisation and emotional exhaustion indices in the dorsolateral prefrontal cortex, which controls for anxiety. Increased brain activation during an attention task, measured using functional MRI, was associated with higher burnout scores in paediatric residents. This study provides a biological basis for the implementation of measures to reduce burnout syndrome at the start of residency training programmes. ©2016 Foundation Acta Paediatrica.

  1. Myotubes from severely obese type 2 diabetic subjects accumulate less lipids and show higher lipolytic rate than myotubes from severely obese non-diabetic subjects.

    Siril S Bakke

    Full Text Available About 80% of patients with type 2 diabetes are classified as overweight. However, only about 1/3 of severely obese subjects have type 2 diabetes. This indicates that several severely obese individuals may possess certain characteristics that protect them against type 2 diabetes. We therefore hypothesized that this apparent paradox could be related to fundamental differences in skeletal muscle lipid handling. Energy metabolism and metabolic flexibility were examined in human myotubes derived from severely obese subjects without (BMI 44±7 kg/m2 and with type 2 diabetes (BMI 43±6 kg/m2. Lower insulin sensitivity was observed in myotubes from severely obese subjects with type 2 diabetes. Lipolysis rate was higher, and oleic acid accumulation, triacylglycerol content, and fatty acid adaptability were lower in myotubes from severely obese subjects with type 2 diabetes compared to severely obese non-diabetic subjects. There were no differences in lipid distribution and mRNA and protein expression of the lipases HSL and ATGL, the lipase cofactor CGI-58, or the lipid droplet proteins PLIN2 and PLIN3. Glucose and oleic acid oxidation were also similar in cells from the two groups. In conclusion, myotubes established from severely obese donors with established type 2 diabetes had lower ability for lipid accumulation and higher lipolysis rate than myotubes from severely obese donors without diabetes. This indicates that a difference in intramyocellular lipid turnover might be fundamental in evolving type 2 diabetes.

    Full Text Available BACKGROUND: The aim of this study was to develop and validate a reliable clinical prediction rule that could be employed to identify patients at higher likelihood of mortality among those with hematological malignancies (HMs and bacterial bloodstream infections (BBSIs. METHODS AND FINDINGS: We conducted a retrospective cohort study in nine Italian hematological units. The derivation cohort consisted of adult patients with BBSI and HMs admitted to the Catholic University Hospital (Rome between January 2002 and December 2008. Survivors and nonsurvivors were compared to identify predictors of 30-day mortality. The validation cohort consisted of patients hospitalized with BBSI and HMs who were admitted in 8 other Italian hematological units between January 2009 and December 2010. The inclusion and exclusion criteria were identical for both cohorts, with type and stage of HMs used as matching criteria. In the derivation set (247 episodes, the multivariate analysis yielded the following significant mortality-related risk factors acute renal failure (Odds Ratio [OR] 6.44, Confidential Interval [CI], 2.36-17.57, P<0.001; severe neutropenia (absolute neutrophil count <100/mm(3 (OR 4.38, CI, 2.04-9.43, P<0.001; nosocomial infection (OR, 3.73, CI, 1.36-10.22, P = 0.01; age ≥65 years (OR, 3.42, CI, 1.49-7.80, P = 0.003; and Charlson Comorbidity Index ≥4 (OR, 3.01, CI 1.36-6.65, P = 0.006. The variables unable to be evaluated at that time (for example, prolonged neutropenia were not included in the final logistic model. The equal-weight risk score model, which assigned 1 point to each risk factor, yielded good-excellent discrimination in both cohorts, with areas under the receiver operating curve of 0.83 versus 0.93 (derivation versus validation and good calibration (Hosmer-Lemshow P = 0.16 versus 0.75.

    2011-04-01

    Full Text Available Within many British Universities and, indeed, across higher education internationally, how best to provide education for sustainable development (ESD has become an increasingly important issue. There is now a widespread view that higher education sectors have a key part to play in preparing societies for the transition to a low carbon economy and the shift towards more sustainable ways of living and working. In the UK, a leading role in this field has been played by the Higher Education Academy and especially its network of 24 Subject Centres, each of which promotes curriculum enhancement in a particular discipline area. The mission of the Higher Education Academy has been to help raise the overall quality of the student learning experience across all disciplines and all Higher Education institutions (HEIs. As part of promoting and supporting many kinds of curriculum innovation and staff development, the HE Academy has championed the cause of ESD. Now, however, as a result of government spending cuts, the Academy is facing severe budget reductions and all its Subject Centres are soon to close. At this pivotal moment, the purpose of this paper is, therefore, to review the HE Academy’s past contribution to ESD and to explore the likely future implications of the demise of its Subject Centres. The paper ends by outlining some ideas as to how the ESD agenda might be advanced in the post-Subject Centre era, in the light of the Academy’s intention to support subject communities under its new structure. The paper has been developed through participation in key committees, engagement with Academy and Subject Centre staff, as well as through a literature review.

    Introduction Members of the human intestinal microbiota are key players in maintaining human health. Alterations in the composition of gut microbial community (dysbiosis) have been linked with important human diseases. Understanding the underlying processes that control community structure, including the bacterial interactions within the microbiota itself, is essential. Bdellovibrio bacteriovorus is a gram-negative bacterium that preys other gram-negative species for survival, acting as a population-balancer. It was found in terrestrial/aquatic ecosystems, and in animal intestines, postulating its presence also in the human gut. Methods The present study was aimed to evaluate, by end-point PCR and qPCR, the presence of B. bacteriovorus in intestinal and faecal biopsy specimens from 92 paediatric healthy subjects and patients, suffering from Inflammatory Bowel Diseases (IBD), Celiac disease and Cystic fibrosis (CF). Results i) B. bacteriovorus was present and abundant only in healthy individuals, while it was heavily reduced in patients, as in the case of IBD and Celiac, while in CF patients and relative controls we observed comparable results; ii) B. bacteriovorus seemed to be mucosa-associated, because all IBD and Celiac biopsies (and related controls) were treated with mucus-removing agents, leaving only the mucosa-attached microflora; iii) B. bacteriovorus abundance was district-dependent, with a major preponderance in duodenum, and gradually decreasing up to rectum; iv) B. bacteriovorus levels significantly dropped in disease status, in duodenum and ileum. Conclusions Results obtained in this study could represent the first step for new therapeutic strategies aimed to restore a balance in the intestinal ecosystem, utilizing Bdellovibrio as a probiotic.

    Gastrostomy fed head or neck cancer patients frequently have impaired speech capacities. Enteral feeding teams frequently depend on laboratorial or anthropometrical parameters for nutritional assessment. In these patients, this study aimed to evaluate: (1) the practicability of Scored - Patient-Generated Subjective Global Assessment (PG-SGA); (2) their nutritional status using the Scored-PG-SGA; (3) association of serum albumin and transferrin values to the nutritional status rating using PG-SGA. On adult outpatients with head or neck cancer under prolonged (> 1 month) gastrostomy feeding, Scored-PGSGA, albumin and transferrin were evaluated during the same appointment. Scored-PG-SGA was easily feasible in 42 patients, even in patients with speech difficulties. Twenty-five patients were moderately/severely undernourished (PG-SGA/B+C). Scored-PG-SGA rated 41 patients as ≥ 2, thus needing nutritional/ pharmacologic intervention. Albumin was low in 13 patients. Transferrin was low in 19 patients. Average albumin and transferrin in moderately/severely undernourished patients (PG-SGA/B+C) was significantly lower than in well-nourished (PG-SGA/A). There was association between Scored- PG-SGA rating, albumin and transferrin. In PEG fed head or neck cancer patients, PGSGA was practicable and useful, even in patients with impaired speaking skills. Most patients displayed moderate/severe malnutrition (PG-SGA/B+C). Scored-PG-SGA rated 41 patients as needing for nutritional/pharmacological intervention. Scored-PG-SGA should be systematically included in the evaluation of these patients. In these patients, albumin and transferrin levels showed relation with Scored-PG-SGA and should be considered as nutritional biomarkers. Copyright AULA MEDICA EDICIONES 2014.

    Accurate identification and management of malnutrition is essential so that patient outcomes can be improved and resources used efficaciously. In malnourished older adults admitted to rehabilitation: 1) report the prevalence, health and aged care use, and mortality of malnourished older adults; 2) determine and compare the criterion (concurrent and predictive) validity of the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and the Mini Nutritional Assessment (MNA) in diagnosing malnutrition; and 3) identify the Scored PG-SGA score cut-off value associated with malnutrition. Observational, prospective cohort. Participants were 57 older adults (65 years and older; mean±standard deviation age=79.1±7.3 years) from two rural rehabilitation units in New South Wales, Australia. Scored PG-SGA; MNA; and the International Statistical Classification of Diseases and Health Related Problems, 10th revision, Australian Modification (ICD-10-AM) classification of malnutrition were compared to establish concurrent validity and report malnutrition prevalence. Length of stay, discharge location, rehospitalization, admission to a residential aged care facility, and mortality were measured to report health-related outcomes and to establish predictive validity. Malnutrition prevalence varied according to assessment tool (ICD-10-AM: 46%; Scored PG-SGA: 53%; MNA: 28%). Using the ICD-10-AM as the reference standard, the Scored PG-SGA ratings (sensitivity 100%, specificity 87%) and score (sensitivity 92%, specificity 84%, ROC AUC [receiver operating characteristics area under the curve]=0.910±0.038) showed strong concurrent validity, and the MNA had moderate concurrent validity (sensitivity 58%, specificity 97%, receiver operating characteristics area under the curve=0.854±0.052). The Scored PG-SGA rating, Scored PG-SGA score, and MNA showed good predictive validity. Malnutrition can increase the risk of longer rehospitalization length of stay, admission to a residential

    A better knowledge of long-term trajectories of cognitive decline is a central feature of the study of the process leading to Alzheimer's dementia. Several factors may mitigate such decline, among which is education, a major risk factor for Alzheimer's disease. The aim of our work was to compare the pattern and duration of clinical trajectories before Alzheimer's dementia in individuals with low and high education within the PAQUID cohort involving 20 years of follow-up. The sample comprises 442 participants with incident Alzheimer's disease (27.2% were male)--171 with low education (mean age=86.2 years; standard deviation=5.3 years) and 271 with higher education (mean age=86.5; standard deviation=5.4)--and 442 control subjects matched according to age, sex and education. At each visit and up to the 20-year follow-up visit, several cognitive and clinical measures were collected and incident cases of Alzheimer's disease clinically diagnosed. The evolution of clinical measures in pre-demented subjects and matched controls was analysed with a semi-parametric extension of the mixed effects linear model. The results show that the first signs of cognitive decline occurred 15 to 16 years before achieving dementia threshold in higher-educated subjects whereas signs occurred at 7 years before dementia in low-educated subjects. There seemed to be two successive periods of decline in higher-educated subjects. Decline started ∼15 to 16 years before dementia with subtle impairment restricted to some cognitive tests and with no impact during the first 7 to 8 years on global cognition, cognitive complaints, or activities of daily living scales. Then, ∼7 years before dementia, global cognitive abilities begin to deteriorate, along with difficulties dealing with complex activities of daily living, the increase in self-perceived difficulties and depressive symptoms. By contrast, lower-educated subjects presented a single period of decline lasting ∼7 years, characterized by

    Full Text Available The relevance of the research is due to the necessity of integration of persons with health limitations and disabilities into the educational space of higher education institutions. With regard to this, the paper is aimed at finding out the extent of readiness of the educational activity subjects for results-oriented cooperation in inclusive educational practice of the higher school. The leading approach to studying this problem is the retrospective interdisciplinary analysis that allows an integrated consideration of the universities' readiness for full-fledged integration of people with health limitations and disabilities into the educational process. In the paper, the results of research into students' attitude toward the disabled and HL people and their readiness for results-oriented cooperation are presented, and the specific problems of psychological and social support rendering are described. The value references system of students with health limitations and disabilities has been found out, and grounds have been provided for having to include the subjects that form a tolerant attitude to special needs people into the student-training content. It has also been proven that qualified professional training has to be ensured for the academic teaching staff, infrastructure has to be provided, and an integrated program has to be developed that would allow personifying the academic process adjusted for the development particularities of students with health limitations. The materials of the paper are of practical importance for educational activity subjects involved into the higher-school inclusive educational practice.

    Based on successive samples totaling more than 5000 higher education students, we scrutinized the reliability, structure, initial validity and normative scores of a brief self-report seven-item scale to screen for the continuum of nighttime insomnia complaints/perceived sleep quality, used by our team for more than a decade, henceforth labeled the Basic Scale on Insomnia complaints and Quality of Sleep (BaSIQS). In study/sample 1 (n = 1654), the items were developed based on part of a larger survey on higher education sleep-wake patterns. The test-retest study was conducted in an independent small group (n = 33) with a 2-8 week gap. In study/sample 2 (n = 360), focused mainly on validity, the BaSIQS was completed together with the Pittsburgh Sleep Quality Index (PSQI). In study 3, a large recent sample of students from universities all over the country (n = 2995) answered the BaSIQS items, based on which normative scores were determined, and an additional question on perceived sleep problems in order to further analyze the scale's validity. Regarding reliability, Cronbach alpha coefficients were systematically higher than 0.7, and the test-retest correlation coefficient was greater than 0.8. Structure analyses revealed consistently satisfactory two-factor and single-factor solutions. Concerning validity analyses, BaSIQS scores were significantly correlated with PSQI component scores and overall score (r = 0.652 corresponding to a large association); mean scores were significantly higher in those students classifying themselves as having sleep problems (p education students. It might be a convenient short tool in research and applied settings to rapidly assess sleep quality or screen for insomnia complaints, and it may be easily used in other populations with minor adaptations.

    This study investigates workers' favoured rotation types by their age and compares means between subjective and actual scores on productivity, quality and musculoskeletal disorders (MSDs). The subjects of research were 422 assembly line units in Hyundai Motor Company. The survey of 422 units focused on the workers' preference for 11 different rotation types and subjective scores for each type's perceived benefits, both by the workers' age. Then, actual scores on production-related indices were traced over a five-year period. The results suggest that different rotation types lead to different results in productivity, product quality and MSDs. Workers tend to perceive job rotation as a helpful method to enhance satisfaction, productivity and product quality more so than the actual production data suggests. Job rotation was especially effective in preventing MSDs for workers aged under 45, while its effects were not clear for the workers aged 45 years or older. Practitioner's Summary: This research presents appropriate rotation type for different age groups. Taking workers' age into account, administrators can use the paper's outcomes to select and implement the suitable rotation type to attain specific goals such as enhancing productivity, improving product quality or reducing MSDs.

  20. Subject-specific tendon-aponeurosis definition in Hill-type model predicts higher muscle forces in dynamic tasks.

    Directory of Open Access Journals (Sweden)

    Pauline Gerus

    Full Text Available Neuromusculoskeletal models are a common method to estimate muscle forces. Developing accurate neuromusculoskeletal models is a challenging task due to the complexity of the system and large inter-subject variability. The estimation of muscles force is based on the mechanical properties of tendon-aponeurosis complex. Most neuromusculoskeletal models use a generic definition of the tendon-aponeurosis complex based on in vitro test, perhaps limiting their validity. Ultrasonography allows subject-specific estimates of the tendon-aponeurosis complex's mechanical properties. The aim of this study was to investigate the influence of subject-specific mechanical properties of the tendon-aponeurosis complex on a neuromusculoskeletal model of the ankle joint. Seven subjects performed isometric contractions from which the tendon-aponeurosis force-strain relationship was estimated. Hopping and running tasks were performed and muscle forces were estimated using subject-specific tendon-aponeurosis and generic tendon properties. Two ultrasound probes positioned over the muscle-tendon junction and the mid-belly were combined with motion capture to estimate the in vivo tendon and aponeurosis strain of the medial head of gastrocnemius muscle. The tendon-aponeurosis force-strain relationship was scaled for the other ankle muscles based on tendon and aponeurosis length of each muscle measured by ultrasonography. The EMG-driven model was calibrated twice - using the generic tendon definition and a subject-specific tendon-aponeurosis force-strain definition. The use of subject-specific tendon-aponeurosis definition leads to a higher muscle force estimate for the soleus muscle and the plantar-flexor group, and to a better model prediction of the ankle joint moment compared to the model estimate which used a generic definition. Furthermore, the subject-specific tendon-aponeurosis definition leads to a decoupling behaviour between the muscle fibre and muscle-tendon unit

    To develop a CT-based prediction score for anastomotic leakage after esophagectomy and compare it to subjective CT interpretation. Consecutive patients who underwent a CT scan for a clinical suspicion of anastomotic leakage after esophagectomy with cervical anastomosis between 2003 and 2014 were analyzed. The CT scans were systematically re-evaluated by two radiologists for the presence of specific CT findings and presence of an anastomotic leak. Also, the original CT interpretations were acquired. These results were compared to patients with and without a clinical confirmed leak. Out of 122 patients that underwent CT for a clinical suspicion of anastomotic leakage; 54 had a confirmed leak. In multivariable analysis, anastomotic leakage was associated with mediastinal fluid (OR = 3.4), esophagogastric wall discontinuity (OR = 4.9), mediastinal air (OR = 6.6), and a fistula (OR = 7.2). Based on these criteria, a prediction score was developed resulting in an area-under-the-curve (AUC) of 0.86, sensitivity of 80%, and specificity of 84%. The original interpretation and the systematic subjective CT assessment by two radiologists resulted in AUCs of 0.68 and 0.75 with sensitivities of 52% and 69%, and specificities of 84% and 82%, respectively. This CT-based score may provide improved diagnostic performance for diagnosis of anastomotic leakage after esophagectomy. (orig.)

    Carbonic anhydrase IX is a member of α-carbonic anhydrases that is preferentially expressed in solid tumors. It enables bicarbonate transport across the plasma membrane, neutralizing intracellular pH and conferring to cancer cells a survival advantage in hypoxic/acidic microenvironments. Overexpression of carbonic anhydrase IX in cancer tissues is regulated by hypoxia inducible factor 1α - mediated transcription and the enzyme is considered a marker of tumor hypoxia and poor outcome. The role of carbonic anhydrase IX in prostate cancer has not been fully clarified and controversy has arisen on whether this enzyme is overexpressed in hypoxic prostate cancer tissues. We analyzed the expression of carbonic anhydrase IX and hypoxia inducible factor 1α in two prostate cancer cell lines, LNCaP and PC-3, and in 110 cancer biopsies, by western blotting and immunocyto/histochemistry. In LNCaP and PC-3 cells, carbonic anhydrase IX was mostly cytoplasmic/nuclear, with very limited membrane localization. Nuclear staining became stronger under hypoxia. When we analyzed carbonic anhydrase IX expression in human prostate cancer biopsies, we found that protein staining positively correlated with hypoxia inducible factor 1α and with Gleason pattern and score, as well as with the novel grading system proposed by the International Society of Urological Pathology for prostate cancer. Once more, carbonic anhydrase IX was mainly cytoplasmic in low grade carcinomas, whereas in high grade tumors was strongly expressed in the nucleus of the neoplastic cell. An association between carbonic anhydrase IX expression level and the main clinic-pathological features involved in prostate cancer aggressiveness was identified. There was a statistically significant association between carbonic anhydrase IX and hypoxia inducible factor 1α in prostate cancer tissues, that identifies the enzyme as a reliable marker of tumor hypoxia. In addition, carbonic anhydrase IX expression positively

    Full Text Available The article is devoted to the difficulties of adaptation of rural students to the various spheres of life of the modern city. These difficulties are considered as a field of activity of higher educational institution, acting as the subject of adaptation of students coming to study from rural areas to the terms of the city. The authors ' point of view on this issue is substantiated by the analysis of data of several sociological surveys conducted in various regions of theRussian Federation. Also the experience of assistance in adaptation of the Mordovia state University named after N. P. Ogarev of the city ofSaransk, which is the largest in the Republic of Mordovia University and which accommodates a large number of rural youth. The relevance and scientific novelty of research consists in allocation of areas of adaptation support of students from rural areas by the higher educational institution.

    Coronary heart disease (CHD) mortality is 70% higher among Indian Asians (IA) than European whites (EW), the reasons for this excess remain unexplained. Coronary artery calcification (CAC) is highly correlated with coronary plaque burden and silent myocardial ischaemia in EW; but fails to identify excess risk in IA. We hypothesised that IA have a higher prevalence of silent myocardial ischaemia compared to EW, despite similar CAC, and this may explain their excess CHD mortality. CAC was measured for 2,369 asymptomatic men and women, aged 35 to 75 years, as part of the London Life Sciences Population (LOLIPOP) study. 518 subjects had CAC scores >100 Agatston units and of these 256 (49%) patients underwent myocardial perfusion scintigraphy (MPS). CAC scores were similar among IA and EW, after adjustment for conventional risk factors. MPS abnormalities were seen in 56 (22%) subjects. Presence of diabetes (P = .03) and increasing CAC (P < .001) were independent predictors for severity of silent myocardial ischaemia. Ethnicity did not influence the prevalence or the extent of silent myocardial ischaemia. MPS did not identify greater ischaemia among IA compared with EW. This appears incongruent with almost 2-fold higher risk of CHD mortality observed in IA.

Psychophysiological factors may trigger or maintain CSCR, though, surprisingly, the association between CSCR and anxiety has yet to be studied. The aims of the present study were threefold: to determine whether 1 Iranian patients with CSCR have higher scores for anxiety, 2 anxiety is lower, if CSCR has been experienced twice, and whether 3 anxiety scores differ between sexes.Methods: A total of 30 patients with CSCR and 30 healthy age- and sex-matched controls took part in the study. A brief face-to-face interview was conducted covering demographic variables and history and occurrence of CSCR and assessing anxiety.Results: Compared to healthy controls, anxiety was significantly higher in both first-time and second-time CSCR patients. In CSCR patients, anxiety scores did not differ between sexes.Conclusion: Higher anxiety scores were observed in Iranian patients with CSCR, irrespective of whether this was the first or second occurrence of CSCR. This suggests there is no psychological adaptation in terms of reduced anxiety among patients with repeated CSCR. Keywords: idiopathic central

    The aim of this study was to investigate the relationship between sleep duration, wake time, and hours studying on high school grades and performance on the Scholastic Aptitude Test (SAT)/ American College Testing (ACT) college entrance exams. Data were collected from 13,071 recently graduated high school seniors who were entering college in the fall of 2014. A column proportions z test with a Bonferroni adjustment was used to analyze proportional differences. Analysis of covariance (ANCOVA) was used to examine mean group differences. Students who woke up prior to 6 a.m. and got less than 8 h of sleep (27 %) were significantly more likely to report studying 11 or more hours per week (30 %), almost double the rate compared to students who got more than 8 h of sleep and woke up the latest (16 %). Post hoc results revealed students who woke up at 7 a.m. or later reported significantly higher high school grades than all other groups (p SAT/ACT scores were from the group that woke up after 7 a.m. but got less than 8 h sleep (M = 1099.5). Their scores were significantly higher than all other groups. This study provides additional evidence that increased sleep and later wake time are associated with increased high school grades. However, this study also found that students who sleep the longest also reported less studying and lower SAT/ACT scores.

    Full Text Available Background: The concept of mental toughness has gained increasing importance among groups other than elite athletes by virtue of its psychological importance and explanatory power for a broad range of health-related behaviors. However, no study has focused so far on the psychological origins of mental toughness. Therefore, the aims of the present study were: to explore, to what extent the psychological profiles of preschoolers aged five were associated with both 1 mental toughness scores and 2 sleep disturbances at age 14, and 3 to explore possible gender differences.Method: Nine years after their first assessment at age five (preschoolers, a total of 77 adolescents (mean age: 14.35 years; SD = 1.22; 42% females took part in this follow-up study. At baseline, both parents and teachers completed the Strengths and Difficulties Questionnaire (SDQ, covering internalizing and externalizing problems, hyperactivity, negative peer relationships, and prosocial behavior. At follow-up, participants completed a booklet of questionnaires covering socio-demographic data, mental toughness, and sleep disturbances.Results: Higher prosocial behavior, lower negative peer relationships, and lower internalizing and externalizing problems at age five, as rated by parents and teachers, were associated with self-reported higher mental toughness and lower sleep disturbances at age 14. At age 14, and relative to males, females had lower MT scores and reported more sleep disturbances.Results: Higher prosocial behavior, lower negative peer relationships, and lower internalizing and externalizing problems at age five, as rated by parents and teachers, predicted self-reported higher mental toughness and lower sleep disturbances at age 14. At age 14, and relative to males, females had lower MT scores and reported more sleep disturbance.Conclusions: The pattern of results suggests that mental toughness traits during adolescence may have their origins in the pre-school years.

    19-Channel Z-Score Neurofeedback (19ZNF) is a modality using 19-electrodes with real-time normative database z-scores, suggesting effective clinical outcomes in fewer sessions than traditional neurofeedback. Thus, monitoring treatment progression and clinical outcome is necessary. The area of focus in this study was a methodology of quantitative analysis for monitoring treatment progression and clinical outcome with 19ZNF. This methodology is noted as the Sites-of-Interest, which included repeated measures analyses of variance (rANOVA) and t-tests for z-scores; it was conducted on 10 cases in a single subject design. To avoid selection bias, the 10 sample cases were randomly selected from a pool of 17 cases that met the inclusion criteria. Available client outcome measures (including self-report) are briefly discussed. The results showed 90% of the pre-post comparisons moved in the targeted direction (z = 0) and of those, 96% (80% Bonferroni corrected) of the t-tests and 96% (91% Bonferroni corrected) of the rANOVAs were statistically significant; thus indicating a progression towards the mean in 15 or fewer 19ZNF sessions. All cases showed and reported improvement in all outcome measures (including quantitative electroencephalography assessment) at case termination.

    Cerebral white matter lesions (WMLs) are radiologic markers of small vessel disease in brain, and inflammatory processes were related to WMLs. We propose to determine if elevated leukocyte count was associated with a higher risk of WMLs. 1586 asymptomatic subjects who visited our hospital for a routine health check-up were enrolled. Leukocyte counts were measured and the presence of moderate to severe WMLs was determined by brain MRI. Thirty (1.9%) had moderate to severe WMLs, and a significant greater proportion (4.1%) of subjects in the highest leukocyte count quartile had moderate to severe WMLs. After adjusting by C-reactive protein, aspirin use and cardiovascular risk factors, the highest quartile of leukocyte count (≥6.7×10⁹/L) was significantly associated with moderate to severe WMLs compared with the lowest quartile [adjusted odds ratio, 4.03; 95% confidence interval, 1.05-15.5]. The authors report for the first time that an elevated leukocyte count is independently associated with moderate to severe WMLs. Copyright © 2010. Published by Elsevier B.V.

    While the detection of subclinical atherosclerosis may provide an opportunity for the prevention of cardiovascular disease (CVD), which currently is a leading cause of death in HIV-infected subjects, its diagnosis is a clinical challenge. We aimed to compare the agreement and diagnostic performance of Framingham, SCORE and D:A:D equations for the recognition of subclinical atherosclerosis in HIV patients and to adjust the D:A:D equation using HIV and CVD variables. Atherosclerosis was evaluated in 203 HIV-infected individuals by measuring the carotid intima-media thickness (IMT). The CVD risk was calculated using the Framingham, SCORE and D:A:D risk equations. Framingham, SCORE and D:A:D equations showed a low agreement with the IMT (Kappa: 0.219, 0.298, 0.244, respectively; p = 0.743) and a moderate predictive performance, (area under the curve [AUC] = 0.686, 0.665 and 0.716, respectively; p = 0.048), with the D:A:D equation being the most accurate. Atherosclerosis was demonstrated in a significant proportion of subjects with low predicted CVD risk by all three algorithms (16.3%, 17.2%, 17.2%, respectively; p = 0.743). In patients with an estimated low CVD risk atherosclerosis was associated with older age (p = 0.012) and low CD4 counts (p = 0.021). A model was developed to adjust the D:A:D equation; a significant increase in accuracy was obtained when CD4 counts and low-grade albuminuria were included (AUC = 0.772; p subclinical atherosclerosis in this population. The accuracy of the D:A:D equation improves when CD4 counts and low-grade albuminuria are incorporated into the equation. © The European Society of Cardiology 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Previous studies revealed a correlation between local brain volume and cognitive function. The aim of the present study was to investigate the correlation between local gray matter volume and the Wechsler Memory Scale-Revised (WMS-R) logical/verbal memory (WMS-R-verbal) score in healthy adults using a 3 Tesla magnetic resonance scanner and voxel-based morphometry (VBM). T1-weighted magnetic resonance images were obtained in 1,169 healthy adults. The T1-weighted images in native space were bias-corrected, spatially normalized, and segmented into gray matter, white matter, and cerebrospinal fluid images with Statistical Parametric Mapping 5. To investigate regionally the specific effects of the WMS-R-verbal score on the gray matter images, simple regression analysis was performed by VBM treating age, total intracranial volume, and gender as confounding covariates. A P value of less than 0.05 corrected with false discovery rate in voxel difference was considered to be statistically significant. Our study showed a significant positive correlation between the WMS-R-verbal score and the bilateral entorhinal cortex volume. In the right entorhinal, T value is 4.75, and the size of the clusters is 155 voxels. In the left entorhinal, T value is 4.08, and the size of the clusters is 23 voxels. A significant negative correlation was not found. To our knowledge, this is the first VBM study showing that entorhinal cortex volume is positively correlated with the WMS-R-verbal score for healthy subjects. Therefore, in our structural neuroimaging study, we add evidence to the hypothesis that the entorhinal cortex is involved in verbal memory processing.

    There is now a substantial body of evidence which indicates that the TaqI A D{sub 2} dopamine receptor (DRD2) minor (Al) allele is associated with alcoholism. In the present study, TaqI A DRD2 alleles and haplotypes of the DRD2 gene were determined in 307 Caucasian (non-Hispanic) subjects. These haplotypes are a combination of closely linked alleles in intron 6 and exon 7 and yield three haplotypes (1, 2, and 4) and six genotypes in Caucasians. The sample under study consisted of 54 individuals who consumed 200 or more alcoholic drinks per month (Group A) and 248 persons who drank less than 200 drinks per month (Group B). The results showed that the DRD2 A1 allele was significantly higher (P < 0.05) in Group A (48.2%) compared to group B (32.7%). Haplotype analysis in the same sample showed Group A having a significantly higher (P < 0.007) prevalence (28.4%) of the 1 haplotype than those in group B (14.0%). The results indicate both these genetic markers in the DRD2 gene are associated with higher alcohol consumption; however, the 1 haplotype appears to be a better marker for this behavior. In conclusion, haplotypes within the DRD2 gene and TaqI A DRD2 alleles (located 20-Kb from the 3{prime} coding region of this gene) are both associated with heavier alcohol consumption. These findings add further evidence to the importance of the gene in alcohol-related behaviors.

    By whole-body MRI (WBMRI), we aimed to examine the frequency and distribution of inflammatory and structural lesions in PsA patients, SpA patients and healthy subjects (HSs), to introduce global WBMRI inflammation/damage scores, and to assess WBMRI's reproducibility and correlation with conventional MRI (convMRI). WBMRI (3.0-T) of patients with peripheral PsA (n = 18) or axial SpA (n = 18) and of HS (n = 12) was examined for proportion of evaluable features (readability) and the presence and pattern of lesions in axial and peripheral joints. Furthermore, global WBMRI scores of inflammation and structural damage were constructed, and WBMRI findings were compared with clinical measures and convMRI (SpA/HS: spine and SI joints; PsA/HS: hand). The readability (92-100%) and reproducibility (intrareader intraclass correlation coefficient: 0.62-1.0) were high in spine/SI joint, but lower in the distal peripheral joints. Wrists, shoulders, knees, ankles and MTP joints were most commonly involved, with frequency of synovitis > bone marrow oedema (BMO) > erosion. WBMRI global BMO scores of peripheral and axial joints were higher in PsA {median 7 [interquartile range (IQR) 3-15]} and SpA [8 (IQR 2-14)] than in HSs [2.5 (IQR 1-4.5)], both P joint scores were ρ = 0.20-0.78. WBMRI allows simultaneous assessment of peripheral and axial joints in PsA and SpA, and the distribution of inflammatory and structural lesions and global scores can be determined. The study strongly encourages further development and longitudinal testing of WBMRI techniques and assessment methods in PsA and SpA. © The Author 2014.

    Full Text Available Health-related quality of life (HRQL for nursing home residents is important, however, the concept of quality of life is broad, encompasses many domains and is difficult to assess in people with dementia. Basic activities of daily living (ADL are measured routinely in nursing homes using the Resident Assessment Instrument-Minimum Data Set Version 2.0 (RAI-MDS and Functional Independence Measure (FIM instrument. We examined the relationship between HRQL and ADL to assess the future possibility of ADL dependency level serving as a surrogate measure of HRQL in residents with dementia. To assess ADL, measures derived from the RAI-MDS and FIM data were gathered for 111 residents at the beginning of our study and at 6-month follow-up. Higher scores for independence in ADL were correlated with higher scores for a disease-specific HRQL measure, the Quality of Life—Alzheimer’s Disease Scale. Preliminary evidence suggests that FIM-assessed ADL is associated with HRQL for these residents. The associations of the dressing and toileting items with HRQL were particularly strong. This finding suggests the importance of ADL function in HRQL. The RAI-MDS ADL scales should be used with caution to evaluate HRQL.

    Balance and gait are essential to maintain physical autonomy, particularly in elderly people. Thus the detection of risk factors of balance and gait impairment appears necessary in order to prevent falls and dependency. The objective of this study was to analyze the impact of demographic, social, clinical, psychological, and biological parameters on the decline in balance and gait assessed by the Tinetti test (TT) after a two-year follow-up. This prospective study was conducted among community-living, young elderly volunteers in the centre "Investigations Preventives et Cliniques" and "Observatoire De l'Age" (Paris, France). Three hundred and forty-four participants aged 63.5 on average were enrolled and performed the TT twice, once at inclusion and again two years later. After the two-year follow-up, two groups were constituted according to whether or not there was a decrease in the TT score: the "TT no-deterioration" group comprised subjects with a decrease of less than two points and the "TT deterioration" group comprised those with a decrease of two points or more. Selected demographic, social, clinical, psychological, and biological parameters for the two groups were then compared. Statistical analysis showed that female sex, advanced age, high body mass index, osteoarticular pain, and a high level of anxiety all have a negative impact on TT score. Knowledge of predictive factors of the onset or worsening of balance and gait disorders could allow clinicians to detect young elderly people who should benefit from a specific prevention program.

    Successful linguistic processing requires efficient encoding of successively-occurring auditory input in a time-constrained manner, especially under noisy conditions. In this study we examined the early neural response dynamics to rapidly-presented successive syllables in schizophrenia participants and healthy comparison subjects, and investigated the effects of noise on these responses. We used magnetoencephalography (MEG) to reveal the time-course of stimulus-locked activity over bilateral auditory cortices during discrimination of syllable pairs that differed either in voice onset time (VOT) or place of articulation (POA), in the presence or absence of noise. We also examined the association of these early neural response patterns to higher-order cognitive functions. The M100 response, arising from auditory cortex and its immediate environs, showed less attenuation to the second syllable in patients with schizophrenia than healthy comparison subjects during VOT-based discrimination in noise. M100 response amplitudes were similar between groups for the first syllable during all three discrimination conditions, and for the second syllable during VOT-based discrimination in quiet and POA-based discrimination in noise. Across subjects, the lack of M100 attenuation to the second syllable during VOT-based discrimination in noise was associated with poorer task accuracy, lower education and IQ, and lower scores on measures of Verbal Learning and Memory and Global Cognition. Because the neural response to the first syllable was not significantly different between groups, nor was a schizophrenia-related difference obtained in all discrimination tasks, early linguistic processing dysfunction in schizophrenia does not appear to be due to general sensory input problems. Rather, data suggest that faulty temporal integration occurs during successive syllable processing when the signal-to-noise ratio is low. Further, the neural mechanism by which the second syllable is

    Subjective pain assessment scales have been widely used for assessing lameness in response to pain, but the accuracy of these scales has been questioned. To assess scale accuracy, 10 lame, presa Canario dogs with osteoarthritis (OA) associated with bilateral hip dysplasia were first treated with mesenchymal stem cells. Then, potential lameness improvement was analyzed using two pain scales (Bioarth and visual analog scale). These data were compared with similar data collected using a force platform with the same animals during a period of 6 months after treatment. The F test for intraclass correlation showed that concordance in pain/lameness scores between the 2 measuring methodologies was not significant (P value ≥ 0.9213; 95 % confidence interval, -0.56, 0.11). Although subjective pain assessment showed improvement after 6 months, force platform data demonstrated those same animals had returned to the initial lameness state. Use of pain assessment scales to measure lameness associated with OA did not have great accuracy and concordance when compared with quantitative force platform gait analysis.

  1. The Role of Family Orientations in Shaping the Effect of Fertility on Subjective Well-being: A Propensity Score Matching Approach.

    This article investigates whether and how having a child impacts an individual's subjective well-being, while taking into account heterogeneity in family attitudes. People with different family orientations have different values, gender attitudes, preferences toward career and family, and expectations about how childbearing can affect their subjective well-being. These differences impact fertility decisions and the effect of parenthood on an individual's life satisfaction. We define three groups of people based on their family orientations: Traditional, Mixed, and Modern. Applying propensity score matching on longitudinal data (British Household Panel Survey), we create groups of individuals with very similar socioeconomic characteristics and family orientations before childbearing. We then compare those who have one child with those who are childless, and those who have two children with those who have only one child. We show that parents are significantly more satisfied than nonparents, and this effect is stronger among men than among women. For men, we do not find significant differences across family orientations groups in the effect of the birth of the first child on life satisfaction. Among women, only Traditional mothers seem to be more satisfied than their childless counterparts. Women who have a second child are never more satisfied than those who have only one child, regardless of their family orientations. Traditional and Mixed men experience a gain in life satisfaction when they have a second child, but this effect is not found for Modern men.

    The correlation between podoplanin expression and extracapsular spread in head and neck squamous cell carcinoma (HNSCC) has never been reported. The purpose of this study was to assess the predictive value of podoplanin expression for this parameter. Subjective immunoreactivity scores and semiquantitative image analysis of podoplanin expression were performed in 67 patients with primary oral squamous cell carcinoma and in their corresponding lymph nodes. Neck classification showed 34 cases (51%) of pN0 and 33 cases (49%) of pN+. Correlation between the levels of podoplanin expression and the histopathological data was established. In lymph nodes, a high level of podoplanin expression correlated with the presence of extracapsular spread by multivariate analysis (p = .03). A strong correlation between subjective and semiquantitative image analysis was observed (r = 0.77; p < .001). A high level of podoplanin expression in lymph node metastases of oral squamous cell carcinoma is independently associated with extracapsular spread. © 2016 Wiley Periodicals, Head Neck 39: 98-108, 2017. © 2016 Wiley Periodicals, Inc.

    Inadequate sleep has been shown to be a contributor to obesity in both children and adults. Less evidence is available for toddlers and among those with higher obesity risk. The objective of this study was to examine the relationship between sleep patterns and body weight development in a group of young obesity-predisposed children, and to assess whether intakes of energy or macronutrients mediate this relationship. Participants included 368 Danish children aged 2-6 years from the Healthy Start Study, a 1.3 year randomised controlled intervention trial. Sleep habits were measured using a 7-day sleep diary. Multivariate linear regression with adjustment for confounders was used to assess the association of sleep duration and sleep variability with 1.3 year changes (Δ) in body mass index (BMI) z-score from baseline to follow-up. The average nighttime sleep duration was 10.7 h (range 8.8-12.5 h). After controlling for potential confounders, a significant inverse association between nighttime sleep duration and ΔBMI z-score (β=-0.090, P=0.046) was observed. This relationship was mediated by energy intake, with all macronutrients contributing to this mediation effect. No associations were found for sleep variability and ΔBMI z-score but baseline intake of added sugars and sugary beverages were positively associated with sleep variability. Shorter sleep duration, mediated by energy intake in early in life, seems a risk factor for weight gain among young obesity-predisposed children.International Journal of Obesity advance online publication, 10 October 2017; doi:10.1038/ijo.2017.216.

    Diffuse large B-cell lymphoma (DLBCL) can be separated into 2 groups: nodal and extranodal disease. The aim of this study was to analyse the clinical features of skin lesions and survival outcomes of cutaneous DLBCL according to the primary tumour site. A total of 44 patients with cutaneous DLBCL were classified as primary cutaneous DLBCL, leg type or cutaneous DLBCL secondary to primary disease. Although skin lesion characteristics did not differ significantly between groups, extensive cutaneous lesions were more often observed in secondary cutaneous DLBCL compared with DLBCL, leg type. Secondary cutaneous DLBCL was more commonly associated with an advanced stage and higher International Prognostic Index score than DLBCL, leg type. DLBCL, leg type demonstrated a better survival outcome than secondary cutaneous DLBCL. The multiplicity of skin lesions and time-point of cutaneous involvement were associated with prognosis in secondary cutaneous DLBCL. Survival outcomes and prognostic factors differ depending on the primary tumour site of cutaneous DLBCL.

    Divergent thinking tasks are commonly used as indicators of creative potential, but traditional scoring methods of ideational originality face persistent problems such as low reliability and lack of convergent and discriminant validity. Silvia et al. (2008) have proposed a subjective top-2 scoring method, where participants are asked to select their two most creative ideas, which then are evaluated for creativity. This method was found to avoid problems with discriminant validity, and to outperform other scoring methods in terms of convergent validity. These findings motivate a more general, systematic analysis of the subjective top-scoring method. Therefore, this study examined how reliability and validity of the originality and fluency scores depend on the number of top-ideas and on time-on-task. The findings confirm that subjective top-scoring avoids the confounding of originality with fluency. The originality score showed good internal consistency, and evidence of reliability was found to increase as a function of the number of top-ideas and of time-on-task. Convergent validity evidence, however, was highest for a time-on-task of about 2 to 3 minutes and when using a medium number of about three top-ideas. Reasons for these findings are discussed together possible limitations of this study and future directions. The article also presents some general recommendations for the assessment of divergent thinking with the subjective top-scoring method. PMID:24790683

    Relative risk reduction with statin therapy has been consistent across nearly all subgroups studied to date. However, in analyses of 2 randomized controlled primary prevention trials (ASCOT [Anglo-Scandinavian Cardiac Outcomes Trial-Lipid-Lowering Arm] and JUPITER [Justification for the Use of Statins in Prevention: An Intervention Trial Evaluating Rosuvastatin]), statin therapy led to a greater relative risk reduction among a subgroup at high genetic risk. Here, we aimed to confirm this observation in a third primary prevention randomized controlled trial. In addition, we assessed whether those at high genetic risk had a greater burden of subclinical coronary atherosclerosis. We studied participants from a randomized controlled trial of primary prevention with statin therapy (WOSCOPS [West of Scotland Coronary Prevention Study]; n=4910) and 2 observational cohort studies (CARDIA [Coronary Artery Risk Development in Young Adults] and BioImage; n=1154 and 4392, respectively). For each participant, we calculated a polygenic risk score derived from up to 57 common DNA sequence variants previously associated with coronary heart disease. We compared the relative efficacy of statin therapy in those at high genetic risk (top quintile of polygenic risk score) versus all others (WOSCOPS), as well as the association between the polygenic risk score and coronary artery calcification (CARDIA) and carotid artery plaque burden (BioImage). Among WOSCOPS trial participants at high genetic risk, statin therapy was associated with a relative risk reduction of 44% (95% confidence interval [CI], 22-60; Pstatin therapy was 3.6% (95% CI, 2.0-5.1) among those in the high genetic risk group and 1.3% (95% CI, 0.6-1.9) in all others. Each 1-SD increase in the polygenic risk score was associated with 1.32-fold (95% CI, 1.04-1.68) greater likelihood of having coronary artery calcification and 9.7% higher (95% CI, 2.2-17.8) burden of carotid plaque. Those at high genetic risk have a greater

    Full Text Available Background: Dissociative states exist on a continuum from nonpathological forms, such as highway hypnosis and day-dreaming, to pathological states of derealization and depersonalization. Claims of communication with deceased individuals, known as mediumship, were once regarded as a pathological form of dissociation, but current definitions recognize the continuum and include distress and functional disability as symptoms of pathology. This study examined the relationship between dissociative symptoms and mediumship in a large convenience sample. Methods: Secondary analyses of cross-sectional survey data were conducted. The survey included demographics, the Dissociation Experience Scale Taxon (DES-T, score range 0-100, as well as questions about instances of mediumship experiences. Summary statistics and linear and logistic regressions explored the relationship between dissociative symptoms and mediumship endorsement. Results: 3,023 participants were included and were mostly middle-aged (51 years ± 16; range 17-96, female (70%, Caucasian (85%, college educated (88%, had an annual income over $50,000 (55%, and were raised Christian (71% but were presently described as Spiritual but not Religious (60%. Mediumship experiences were endorsed by 42% of participants, the experiences usually began in childhood (81%, and 53% had family members who reported similar experiences. The mean DES-T score across all participants was 14.4 ± 17.3, with a mean of 18.2 ± 19.3 for those claiming mediumship experiences and 11.8 ± 15.2 for those who did not (t = -10.3, p < 0.0005. The DES-T threshold score for pathological dissociation is 30. Conclusions: On average, individuals claiming mediumship experiences had higher dissociation scores than non-claimants, but neither group exceeded the DES-T threshold for pathology. Future studies exploring dissociative differences between these groups may benefit from using more comprehensive measures of dissociative symptoms

    Full Text Available Verbal fluency tests are used as a measure of executive functions and language, and can also be used to evaluate semantic memory. We analyzed the influence of education, gender and age on scores in a verbal fluency test using the animal category, and on number of categories, clustering and switching. We examined 257 healthy participants (152 females and 105 males with a mean age of 49.42 years (SD = 15.75 and having a mean educational level of 5.58 (SD = 4.25 years. We asked them to name as many animals as they could. Analysis of variance was performed to determine the effect of demographic variables. No significant effect of gender was observed for any of the measures. However, age seemed to influence the number of category changes, as expected for a sensitive frontal measure, after being controlled for the effect of education. Educational level had a statistically significant effect on all measures, except for clustering. Subject performance (mean number of animals named according to schooling was: illiterates, 12.1; 1 to 4 years, 12.3; 5 to 8 years, 14.0; 9 to 11 years, 16.7, and more than 11 years, 17.8. We observed a decrease in performance in these five educational groups over time (more items recalled during the first 15 s, followed by a progressive reduction until the fourth interval. We conclude that education had the greatest effect on the category fluency test in this Brazilian sample. Therefore, we must take care in evaluating performance in lower educational subjects.

    In recent years, the use of learning management system by universities has been increasingly growing. However, the results of several studies have revealed that students do not fully use the information systems. The present study proposes a model which investigates the influence of three constructs of perceived ease of use, perceived usefulness, and subjective norm on behavior intention to use of learning management system. The sample size was 216 Malaysian undergraduate students. The results of the study revealed that the proposed model accounts for 31.1 % variance of behavior intention to use.

Data from over 1,800 students in sections with access to the online study questions show that those students scored a statistically significant average of 6.6% points higher on the exam questions analyzed than students in sections without access to the study questions. This difference was greater than the average amount necessary to raise students’ exam grades by one grade (e.g., from a “B-” to a “B”. In addition, there was a higher correlation between number of questions answered and success on exam questions on material related to the study questions than between number of questions answered and success on exam questions on material unrelated to the study questions. The online study question system required substantial effort to set up, but required minimal effort to maintain and was effective in significantly raising average exam scores for even very large course sections.

    Patients with rheumatoid arthritis (RA) exhibit an increased risk of dementia. Disease-modifying antirheumatic drugs (DMARDs) are commonly used to slow RA progression, but studies investigating the relationship between DMARDs and dementia in patients with RA are lacking. We investigated the relationship between DMARDs and dementia in patients with RA. Using the National Health Insurance Research Database, patients aged ≥20years, who were newly diagnosed with RA between 2000 and 2011 were identified. Patients with RA who had dementia comprised the dementia group, and patients with RA who did not have dementia comprised the control group. The groups were matched at a 1:1 ratio by the propensity score. DMARDs were categorized into conventional synthetic DMARDs (csDMARDs) and biological DMARDs (bDMARDs). Logistic regression models were used to calculate the odds ratio and 95% confidence interval (CI) to evaluate the association between DMARD use and the risk of dementia in patients with RA. A total of 957 patients with RA and dementia, and 957 patients with RA but not dementia, were enrolled. The risk of dementia was determined to be 1.63-fold higher in patients with RA with csDMARD use than in those without csDMARD use (95% CI=1.33-2.00). No significant risk of dementia was observed in patients with RA who used bDMARDs compared with their counterparts. However, patients with RA who used hydroxychloroquine, methotrexate, and sulfasalazine exhibited significant risks of dementia, irrespective of cumulative exposure days. Patients with RA who used csDMARDs exhibit significant association with dementia. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

  18. Heavy social drinkers score higher on implicit wanting and liking for alcohol than alcohol-dependent patients and light social drinkers.

    Automatic hedonic ("liking") and incentive ("wanting") processes are assumed to play an important role in addiction. Whereas some neurobiological theories suggest that these processes become dissociated when drug use develops into an addiction (i.e., "liking" becomes weaker, whereas "wanting" becomes exaggerated; e.g., Robinson & Berridge, 1993), other theories suggest that there is a linear relationship between these two processes (i.e., both "liking" and "wanting" increase equally; e.g., Koob & Le Moal, 1997). Our aim was to examine "wanting" and "liking" in three groups of participants: alcohol-dependent patients, heavy social drinkers, and light social drinkers. Participants performed two different single target implicit association tests (ST-IATs; e.g., Bluemke & Friese, 2007) and explicit ratings that were designed to measure "liking" and "wanting" for alcohol. Our results are in sharp contrast with the theories of both Robinson and Berridge and Koob and Le Moal: heavy drinkers had higher scores than light drinkers and alcohol-dependent patients on both the wanting ST-IAT and the liking ST-IAT. There were no differences between alcohol-dependent patients and light drinkers. Explicit ratings mirrored these results. These findings suggest that our ST-IATs are not valid measures of "wanting" and "liking". Instead, they might assess more complex knowledge regarding participants' experiences and goals. These findings suggest that the relationship between drug consumption and appetitive drug associations is not linear, highlighting the importance of testing both sub-clinical and clinical samples in future research.

    Autism is a disorder of neural development characterized by impairments in communication, social interaction, restricted interests and repetitive behavior. The etiology of autism is poorly understood, the evidence indicates that inflammation may play a key role. In autism a high prevalence of gastrointestinal disturbances is reported, that are linked to a low-grade chronic inflammation of the intestinal mucosa. High mobility group box 1 protein (HMGB1) is an intranuclear protein that can be passively released from necrotic cells or actively secreted under inflammatory conditions as alarmin or late proinflammatory cytokine. The objective of this study was to measure plasma levels of HMGB1 in individuals with autism and to analyze their association with gastrointestinal symptoms. The study involved 31 subjects with low-functioning autistic disorder aged 2-22 years and 16 healthy controls. Plasma HMGB1 levels were significantly higher in individuals with autism than in controls (13.8+/-11.7 ng/ml vs. 7.90+/-4.0 ng/ml, pautism and its possible association with GI symptoms.

    Full Text Available We analyzed multiple measures of the autonomic nervous system (ANS based on electrodermal activity (EDA and heart rate variability (HRV for young healthy subjects undergoing 24-h sleep deprivation. In this study, we have utilized the error awareness test (EAT every 2 h (13 runs total, to evaluate the deterioration of performance. EAT consists of trials where the subject is presented words representing colors. Subjects are instructed to press a button (“Go” trials or withhold the response if the word presented and the color of the word mismatch (“Stroop No-Go” trial, or the screen is repeated (“Repeat No-Go” trials. We measured subjects' (N = 10 reaction time to the “Go” trials, and accuracy to the “Stroop No-Go” and “Repeat No-Go” trials. Simultaneously, changes in EDA and HRV indices were evaluated. Furthermore, the relationship between reactiveness and vigilance measures and indices of sympathetic control based on HRV were analyzed. We found the performance improved to a stable level from 6 through 16 h of deprivation, with a subsequently sustained impairment after 18 h. Indices of higher frequencies of EDA related more to vigilance measures, whereas lower frequencies index (skin conductance leve, SCL measured the reactiveness of the subject. We conclude that indices of EDA, including those of the higher frequencies, termed TVSymp, EDASymp, and NSSCRs, provide information to better understand the effect of sleep deprivation on subjects' autonomic response and performance.

    Appropriate home management can alleviate many of the consequences of diarrhea including malnutrition, impaired development, growth faltering, and mortality. Maternal cognitive ability, years of schooling, and acquired academic skills are hypothesized to improve child health by improving maternal child care practices, such as illness management. Using information collected longitudinally in 1996-1999 from 466 rural Guatemalan women with children schooling, academic skills, and scores on the Raven's Progressive Matrices and an illness management index (IMI). Women scoring in the lowest and middle tertiles of academic skills scored lower on the IMI compared to women in the highest tertile (-0.24 [95% CI: -0.54, 0.07]; -0.30 [95% CI: -0.54, -0.06], respectively) independent of sociodemographic factors, schooling, and Raven's scores. Among mothers with less than 1 year of schooling, scoring in the lowest tertile on the Raven's Progressive Matrices compared to the highest was significantly associated with scoring one point lower on the IMI (-1.18 [95% CI: -2.20, -0.17]). Greater academic skills were independently associated with maternal care during episodes of infant diarrhea. Schooling of young girls and/or community based programs that provide women with academic skills such as literacy, numeracy and knowledge could potentially improve mothers' care giving practices.

    Although exercise increases HDL-cholesterol, exercise-induced changes in HDL metabolism have been little explored. Lipid transfer to HDL is essential for HDL's role in reverse cholesterol transport. We investigated the effects of acute exhaustive exercise on lipid transfer to HDL. We compared plasma lipid, apolipoprotein and cytokine levels and in vitro transfer of four lipids from a radioactively labeled lipid donor nanoemulsion to HDL in sedentary individuals (n = 28) and in marathon runners (n = 14) at baseline, immediately after and 72 h after a marathon. While HDL-cholesterol concentrations and apo A1 levels were higher in marathon runners, LDL-cholesterol, apo B and triacylglycerol levels were similar in both groups. Transfers of non-esterified cholesterol [6.8 (5.7-7.2) vs. 5.2 (4.5-6), p = 0.001], phospholipids [21.7 (20.4-22.2) vs. 8.2 (7.7-8.9), p = 0.0001] and triacylglycerol [3.7 (3.1-4) vs. 1.3 (0.8-1.7), p = 0.0001] were higher in marathon runners, but esterified-cholesterol transfer was similar. Immediately after the marathon, LDL- and HDL-cholesterol concentrations and apo A1 levels were unchanged, but apo B and triacylglycerol levels increased. Lipid transfer of non-esterified cholesterol [6.8 (5.7-7.2) vs. 5.8 (4.9-6.6), p = 0.0001], phospholipids [21.7 (20.4-22.2) vs. 19.1 (18.6-19.3), p = 0.0001], esterified-cholesterol [3.2 (2.2-3.8) vs. 2.3 (2-2.9), p = 0.02] and triacylglycerol [3.7 (3.1-4) vs. 2.6 (2.1-2.8), p = 0.0001] to HDL were all reduced immediately after the marathon but returned to baseline 72 h later. Running a marathon increased IL-6 and TNF-α levels, but after 72 h these values returned to baseline. Lipid transfer, except esterified-cholesterol transfer, was higher in marathon runners than in sedentary individuals, but the marathon itself acutely inhibited lipid transfer. In light of these novel observations, further study is required to clarify how these metabolic changes can influence HDL composition and

    The risks during early growth on becoming overweight in adulthood are widely studied in humans. However, early-life predictive factors for canine adult overweight and obesity have not yet been studied. To identify factors that may help explain the development of overweight and obesity at adulthood in dogs, a longitudinal study of 2 years was conducted in 24 female Beagle dogs of the same age, sexual status, and raised under identical environmental conditions. By means of a hierarchical classification on principal components with the following quantitative values: fat-free mass (FFM), percentage fat mass and pelvic circumference at 2 years of age, three groups of dogs were established and were nominally named: ideal weight (IW, n = 9), slightly overweight (OW1, n = 6) and overweight (OW2, n = 9). With the aim of identifying predictive factors of development of obesity at adulthood parental characteristics, growth pattern, energy balance and plasma factors were analysed by logistic regression analysis. At 24 months, the group compositions were in line with the body condition scores (BCS 1-9) values of the IW (5 or 6/9), the OW1 (6/9) and the OW2 (7 or 8/9) groups. Logistic regression analysis permitted the identification of neonatal growth rate during the first 2 weeks of life (GR2W) and BCS at 7 months as predictors for the development of obesity at adulthood. Seventy percent of dogs with either GR2W >125% or with BCS > 6/9 at 7 months belonged to the OW2 group. Results from energy intake and expenditure, corrected for FFM, showed that there was a greater positive energy imbalance between 7 and 10 months for the OW2, compared to the IW group. This study expands the understanding of previously reported risk factors for being overweight or obese in dogs, establishing that (i) 15 out of 24 of the studied dogs became overweight and (ii) GR2W and BCS at 7 months of age could be used as predictive factors as overweight adult dogs in the OW2 group

    A score based on diet and lifestyle recommendations from the AHA has been associated with cardiovascular risk factors. We aimed to assess whether the diet components alone were associated with metabolic syndrome (MetS) and allostatic load (AL; a composite measure of 10 physiologically dysregulated variables). The diet score ranged from 0 to 90 and included intake components for dietary fats, fruits and vegetables, whole grains, salt, added sugars, and alcohol and was tested in a cross-sectional analysis of 1318 Puerto Rican adults (aged 45-75 y; 72% women) living in Boston, MA. The mean ± SD diet score was 28.0 ± 9.9 for men and 30.0 ± 10.1 for women. Replicating findings from a previous study in this cohort that used both the diet and lifestyle components, we observed associations between the diet-only score and insulin, waist circumference, and HDL cholesterol. We found novel significant associations between the continuous diet score and AL components, namely an inverse association with urinary cortisol and a positive association with serum dehydroepiandrosterone sulfate in women as well as an inverse association with urinary norepinephrine in men (all P diet score units were associated with 22% (95% CI: 1, 38; P = 0.043) lower odds of having ≥6 (vs. ≤2) dysregulated AL components in women. In men, every 10 diet score units were associated with lower odds of MetS (OR: 0.69; 95% CI: 0.52, 0.93; P = 0.016). Following AHA recommendations for a healthy diet may protect against the development of components of MetS and AL in Puerto Rican adults.

    Full Text Available In all psychological tests, scoring should be of concern for examiners because the accuracy of results depends, at some extent, on the quality of the correction. This work aims to examine the correction, by different psychologists, of the scores for the Wechsler Intelligence Scale for Children (WISC-III subtests of Similarities, Vocabulary and Comprehension since these are the subtests where examiner's subjectivity seemingly most influences scoring. Forty two psychologists from different states in Brazil participated in this study. They corrected the answers of six test protocols randomly selected from a standardization sample for the Brazilian context. Taking as reference the total scores, the Vocabulary subtest showed greater variability in score, followed by the Comprehension one. Considering the total number of items tested in each subtest, Similarities had the highest agreement among raters. The results showed that all the three subtests involve subjectivity on behalf of the examiner to score the answers. Continuing in this study, we also aim to determine test reliability based on interrater agreement.

  6. An objective fluctuation score for Parkinson's disease.

    Full Text Available Establishing the presence and severity of fluctuations is important in managing Parkinson's Disease yet there is no reliable, objective means of doing this. In this study we have evaluated a Fluctuation Score derived from variations in dyskinesia and bradykinesia scores produced by an accelerometry based system.The Fluctuation Score was produced by summing the interquartile range of bradykinesia scores and dyskinesia scores produced every 2 minutes between 0900-1800 for at least 6 days by the accelerometry based system and expressing it as an algorithm.This Score could distinguish between fluctuating and non-fluctuating patients with high sensitivity and selectivity and was significant lower following activation of deep brain stimulators. The scores following deep brain stimulation lay in a band just above the score separating fluctuators from non-fluctuators, suggesting a range representing adequate motor control. When compared with control subjects the score of newly diagnosed patients show a loss of fluctuation with onset of PD. The score was calculated in subjects whose duration of disease was known and this showed that newly diagnosed patients soon develop higher scores which either fall under or within the range representing adequate motor control or instead go on to develop more severe fluctuations.The Fluctuation Score described here promises to be a useful tool for identifying patients whose fluctuations are progressing and may require therapeutic changes. It also shows promise as a useful research tool. Further studies are required to more accurately identify therapeutic targets and ranges.

  9. Syncopation and the score.

    Full Text Available The score is a symbolic encoding that describes a piece of music, written according to the conventions of music theory, which must be rendered as sound (e.g., by a performer before it may be perceived as music by the listener. In this paper we provide a step towards unifying music theory with music perception in terms of the relationship between notated rhythm (i.e., the score and perceived syncopation. In our experiments we evaluated this relationship by manipulating the score, rendering it as sound and eliciting subjective judgments of syncopation. We used a metronome to provide explicit cues to the prevailing rhythmic structure (as defined in the time signature. Three-bar scores with time signatures of 4/4 and 6/8 were constructed using repeated one-bar rhythm-patterns, with each pattern built from basic half-bar rhythm-components. Our manipulations gave rise to various rhythmic structures, including polyrhythms and rhythms with missing strong- and/or down-beats. Listeners (N = 10 were asked to rate the degree of syncopation they perceived in response to a rendering of each score. We observed higher degrees of syncopation in time signatures of 6/8, for polyrhythms, and for rhythms featuring a missing down-beat. We also found that the location of a rhythm-component within the bar has a significant effect on perceived syncopation. Our findings provide new insight into models of syncopation and point the way towards areas in which the models may be improved.

    It has been reported that various types of mammalian muscle fibers differ regarding the content of several metabolites at rest. However, to our knowledge no data have been reported in the literature, concerning the muscle energetic status at rest in high class athletes when considering the dominant and non-dominant leg separately. We have hypothesised that due to higher mechanical loads on the dominant leg in athletes, the metabolic profile in the dominant leg at rest in the calf muscles, characterized by [PCr], [ADP(free)], [AMP(free)] and DeltaG(ATP), will significantly differ among endurance athletes, sprinters and untrained individuals. In this study we determined the DeltaG(ATP) and adenine phosphates concentrations in the dominant and non-dominant legs in untrained subjects (n = 6), sprinters (n = 10) and endurance athletes (n = 7) at rest. The (mean +/- SD) age of the subjects was 23.4 +/- 4.3 years. Muscle metabolites were measured in the calf muscles at rest, by means of (31)P-MRS, using a 4.7 T superconducting magnet (Bruker). When taking into account mean values in the left and right leg, phosphocreatine concentration ([PCr]) and DeltaG(ATP) were significantly lower (psprinters (p = 0.01) and untrained subjects (p = 0.02) (25.91 +/- 2.87 mM; 30.02 +/- 3.12 mM and 30.71 +/- 2.88 mM, respectively). The [ADP(free)] was significantly higher (p = 0.02) in endurance athletes than in sprinters and untrained subjects (p = 0.02) (42.19 +/- 13.44 microM; 27.86 +/- 10.19 microM; 25.35 +/- 10.97 microM, respectively). The DeltaG(ATP) in the dominant leg was significantly lower (p = 0.02) in endurance athletes than in sprinters and untrained subjects (p = 0.01) (-60.53 +/- 2.03 kJ.M(-1); -61.82 +/- 1.05 kJ.M(-1), -62.29 +/- 0.73 kJ.M(-1), respectively). No significant differences were found when comparing [PCr], [ADP(free)], [AMP(free)], [Mg(2+)(free)], DeltaG(ATP) in the dominant leg and the mean values for both legs in sprinters and untrained subjects.

    Full Text Available Abstract Background The oncofetal protein insulin-like growth factor II mRNA binding protein 3 (IMP3 is an important factor for cell-migration and adhesion in malignancies. Recent studies have shown a remarkable overexpression of IMP3 in different human malignant neoplasms and also revealed it as an important prognostic marker in some tumor entities. To our knowledge, IMP3 expression has not been investigated in prostate carcinomas so far. Methods Immunohistochemical stainings for IMP3 were performed on tissue microarray (TMA organized samples from 507 patients: 31 normal prostate tissues, 425 primary carcinomas and 51 prostate cancer metastases or castration-resistant prostate cancers (CRPC. IMP3 immunoreactivity was semiquantitatively scored and correlated with clinical-pathologic parameters including survival. Results IMP3 is significantly stronger expressed in prostate carcinomas compared to normal prostate tissues (p Conclusions Although IMP3 is overexpressed in a significant proportion of prostate cancer cases, which might be of importance for novel therapeutic approaches, it does not appear to possess any immediate diagnostic or prognostic value, limiting its potential as a tissue biomarker for prostate cancer. These results might be corroborated by the fact, that two independent tumor cohorts were separately reviewed.

    What is the impact of smoking behaviour on seminal, hormonal and male genital tract ultrasound parameters in subjects seeking medical care for couple infertility? In males of infertile couples, current smokers (CS), when compared with non-smokers, show lower ejaculate and ultrasound-derived seminal vesicles (SV) volume, despite higher testosterone levels. Data on the effects of smoking on male fertility are conflicting. A correlation between smoking and reduced semen parameters has been reported, however, with a high heterogeneity among studies. An association between smoking behaviour and higher testosterone levels in men has been described in several, but not all, the previous studies. No study has systematically evaluated the impact of smoking on the male genital tract ultrasound characteristics. Retrospective cross-sectional analysis of a consecutive series of 426 subjects seeking medical care for couple infertility from January 2010 to July 2013. From the entire cohort, 394 men (age 36.0 ± 8.0 years) free of genetic abnormalities were selected. All subjects underwent a complete andrological and physical examination, biochemical and hormonal assessment, scrotal and transrectal colour-Doppler ultrasound and semen analysis (including seminal interleukin-8 levels, sIL-8) within the same day. Among the patients evaluated, 229 were never smokers (NS), 56 past smokers (PS) and 109 CS. When CS were compared with the rest of the sample (non-smokers, NS + PS), in a multivariate model (analysis of covariance, ANCOVA) adjusted for age, lifestyle (including alcohol, cannabis and physical activity), BMI and sex hormone-binding globulin, significantly higher androgen (total testosterone, P = 0.001; calculated free testosterone, P fertile men, and therefore true normative data of sonographic parameters cannot be inferred. Due to the cross-sectional nature of our study, neither a causality hypothesis nor mechanistic models can be drawn. Finally, this is a retrospective study

    Full Text Available This paper is devoted to one of the key moments in liturgical studies in Russian higher church education. This moment was outwardly marked by the introduction of the new term “liturgics” instead of the old term “church antiquities” in the 1840s. The article shows the role of Professor Dolotsky in the development of liturgics as a science and an academic subject. Based on the analysis of survived manuscript documents, lithoprinted lecture notes and papers, we demonstrate that the introduction of the term “liturgics” at Saint-Petersburg Theological Academy in 1849–1853 and its following adoption in higher church education took place with a direct involvement of V. I. Dolotsky. Employing historical approach, Dolotsky signifi cantly broadened the content of his course of lectures, supplementing it with historical data. Dolotsky’s scholarly interests can be identifi ed on the basis of his articles, academic course programmes and lithoprinted lecture notes. They were related, above all, to text analysis of variable parts of church service, particularly holiday service. Besides, Dolotsky expressed interest in the origin of Holy days and their orders in antiquity. Here, by means of the historical approach, Dolotsky made use of the evidence of ancient Holy Fathers and emphasised the importance of employing liturgical sources of heterodox confessions that had common origins with the Orthodox Church. Thus, Dolotsky came to be the first Russian scholar of liturgics and provided a foundation for the further development of historical liturgics in Russian theological science.

    Coreceptor switching from CCR5 to CXCR4 is common during chronic HIV-1 infection, but is even more common in individuals who have failed antiretroviral therapy (ART). Prior studies have suggested rapid mutation and/or recombination of HIV-1 envelope (env) genes during coreceptor switching. We compared the functional and genotypic changes in env of viruses from viremic subjects who had failed ART just before and after coreceptor switching and compared those to viruses from matched subjects without coreceptor switching. Analysis of multiple unique functional env clones from each subject revealed extensive diversity at both sample time points and rapid diversification of sequences during the 4-month interval in viruses from both 9 subjects with coreceptor switching and 15 control subjects. Only two subjects had envs with evidence of recombination. Three findings distinguished env clones from subjects with coreceptor switching from controls: (1) lower entry efficiency via CCR5; (2) longer V1/V2 regions; and (3), lower nadir CD4 T cell counts during prior years of infection. Most of these subjects harbored virus with lower replicative capacity associated with protease (PR) and/or reverse transcriptase inhibitor resistance mutations, and the extensive diversification tended to lead either to improved entry efficiency via CCR5 or the gain of entry function via CXCR4. These results suggest that R5X4 or X4 variants emerge from a diverse, low-fitness landscape shaped by chronic infection, multiple ART resistance mutations, the availability of target cells, and reduced entry efficiency via CCR5.

    The coronary risk in diabetes (CoRDia) trial (n = 211) compares the effectiveness of usual diabetes care with a self-management intervention (SMI), with and without personalised risk information (including genetics), on clinical and behavioural outcomes. Here we present an assessment of randomisation, the cardiac risk genotyping assay, and the genetic characteristics of the recruits. Ten-year coronary heart disease (CHD) risk was calculated using the UKPDS score. Genetic CHD risk was determined by genotyping 19 single nucleotide polymorphisms (SNPs) using Randox's Cardiac Risk Prediction Array and calculating a gene score (GS). Accuracy of the array was assessed by genotyping a subset of pre-genotyped samples (n = 185). Overall, 10-year CHD risk ranged from 2-72 % but did not differ between the randomisation groups (p = 0.13). The array results were 99.8 % concordant with the pre-determined genotypes. The GS did not differ between the Caucasian participants in the CoRDia SMI plus risk group (n = 66) (p = 0.80) and a sample of UK healthy men (n = 1360). The GS was also associated with LDL-cholesterol (p = 0.05) and family history (p = 0.03) in a sample of UK healthy men (n = 1360). CHD risk is high in this group of T2D subjects. The risk array is an accurate genotyping assay, and is suitable for estimating an individual's genetic CHD risk.

    Background: Recent studies suggest that meat intake is associated with diabetes-related phenotypes. However, whether the associations of meat intake and glucose and insulin homeostasis are modified by genes related to glucose and insulin is unknown. Objective: We investigated the associations of meat intake and the interaction of meat with genotype on fasting glucose and insulin concentrations in Caucasians free of diabetes mellitus. Design: Fourteen studies that are part of the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium participated in the analysis. Data were provided for up to 50,345 participants. Using linear regression within studies and a fixed-effects meta-analysis across studies, we examined 1) the associations of processed meat and unprocessed red meat intake with fasting glucose and insulin concentrations; and 2) the interactions of processed meat and unprocessed red meat with genetic risk score related to fasting glucose or insulin resistance on fasting glucose and insulin concentrations. Results: Processed meat was associated with higher fasting glucose, and unprocessed red meat was associated with both higher fasting glucose and fasting insulin concentrations after adjustment for potential confounders [not including body mass index (BMI)]. For every additional 50-g serving of processed meat per day, fasting glucose was 0.021 mmol/L (95% CI: 0.011, 0.030 mmol/L) higher. Every additional 100-g serving of unprocessed red meat per day was associated with a 0.037-mmol/L (95% CI: 0.023, 0.051-mmol/L) higher fasting glucose concentration and a 0.049–ln-pmol/L (95% CI: 0.035, 0.063–ln-pmol/L) higher fasting insulin concentration. After additional adjustment for BMI, observed associations were attenuated and no longer statistically significant. The association of processed meat and fasting insulin did not reach statistical significance after correction for multiple comparisons. Observed associations were not modified by genetic

    Several biomarkers have been proposed for detecting Alzheimer's disease (AD) in its earliest stages, that is, in the predementia stage. In an attempt to find noninvasive biomarkers, researchers have investigated the feasibility of neuroimaging tools, such as MRI, SPECT as well as neurophysiological measurements using EEG. Moreover, the increase of EEG alpha3/alpha2 frequency power ratio has been associated with AD-converters subjects with mild cognitive impairment (MCI). To study the association of alpha3/alpha2 frequency power ratio with regional cerebral blood flow (rCBF) changes in subjects with MCI. Twenty-seven adult subjects with MCI underwent EEG recording and perfusion single-photon emission computed tomography (SPECT) evaluation. The alpha3/alpha2 frequency power ratio was computed for each subject. Two groups were obtained according to the median values of alpha3/alpha2, at a cut-off of 1.17. Correlation between brain perfusion and EEG markers were detected. Subjects with higher alpha3/alpha2 frequency power ratio showed a constant trend to a lower perfusion than low alpha3/alpha2 group. The two groups were significantly different as about the hippocampal volume and correlation with the theta frequency activity. There is a complex interplay between cerebral blood flow, theta frequency activity, and hippocampal volume in MCI patients with prodromal Alzheimer's disease, characterized by higher EEG alpha3/alpha2 frequency power ratio.

    Ginsburg, Rogers, and Maslow, humanistic theorists, have maintained that the self is an emergent characteristic of one's biological makeup. The relationship between physical self-efficacy as an appraisal of subjective biology and self-actualization was examined in a sample of 160 black and white participants. An r of .46 supports the association of subjective biology and self-actualization. Whereas there were no gender or racial differences in scores on self-actualization, men scored higher on physical self-efficacy and subscales of perceived physical ability and perceived self-presentation confidence.

    OBJECTIVE To evaluate agreement among diplomates of the American College of Veterinary Anesthesia and Analgesia for scores determined by use of a simple descriptive scale (SDS) or a composite grading scale (CGS) for quality of recovery of horses from anesthesia and to investigate use of 3-axis accelerometry (3AA) for objective evaluation of recovery. ANIMALS 12 healthy adult horses. PROCEDURES Horses were fitted with a 3AA device and then were anesthetized. Eight diplomates evaluated recovery by use of an SDS, and 7 other diplomates evaluated recovery by use of a CGS. Agreement was tested with κ and AC1 statistics for the SDS and an ANOVA for the CGS. A library of mathematical models was used to map 3AA data against CGS scores. RESULTS Agreement among diplomates using the SDS was slight (κ = 0.19; AC1 = 0.22). The CGS scores differed significantly among diplomates. Best fit of 3AA data against CGS scores yielded the following equation: RS = 9.998 × SG0.633 × ∑UG0.174, where RS is a horse's recovery score determined with 3AA, SG is acceleration of the successful attempt to stand, and ∑UG is the sum of accelerations of unsuccessful attempts to stand. CONCLUSIONS AND CLINICAL RELEVANCE Subjective scoring of recovery of horses from anesthesia resulted in poor agreement among diplomates. Subjective scoring may lead to differences in conclusions about recovery quality; thus, there is a need for an objective scoring method. The 3AA system removed subjective bias in evaluations of recovery of horses and warrants further study.

    Full Text Available Aim: The study aimed at assessing the quality of sleep in seniors. Another objective was to determine the impact of gender, age, type of residence and taking sleeping medication on the quality of sleep. Design: A cross-sectional study. Methods: Data were collected using the standardized Pittsburgh Sleep Quality Index (PSQI questionnaire. The sample comprised 146 seniors living in the Moravian-Silesian Region, Czech Republic. The survey was conducted from January 2014 to the end of October 2014 in a long-term chronic care department of a selected hospital, two retirement homes and among seniors living in their own homes. Results: Thirty-five (24% seniors had their global PSQI scores of 5 (i.e. the highest score indication good sleep quality or less. The remaining 111 (76% participants were shown to suffer from impaired sleep quality as their global PSQI scores were 6 or higher. There were statistically significant differences in component scores between seniors with the global PSQI scores of 5 or less and those with higher scores. The best quality of sleep was observed in females, seniors in the 65–74 age category and those sharing their own homes with their spouses or partners. Conclusion: Subjective sleep quality assessment varies significantly with respect to gender, age, type of residence and use of sleeping medication. Keywords: sleep quality, PSQI, subjective assessment, senior.

    Providing well-being and maintaining good health are main objectives subjects seek from diet. This manuscript describes the development and preliminary validation of an instrument assessing well-being associated with food and eating habits in a general healthy population. Qualitative data from 12 groups of discussion (102 subjects) conducted with healthy subjects were used to develop the core of the Well-being related to Food Questionnaire (Well-BFQ). Twelve other groups of discussion with subjects with joint (n = 34), digestive (n = 32) or repetitive infection complaints (n = 30) were performed to develop items specific to these complaints. Five main themes emerged from the discussions and formed the modular backbone of the questionnaire: "Grocery shopping", "Cooking", "Dining places", "Commensality", "Eating and drinking". Each module has a common structure: items about subject's food behavior and items about immediate and short-term benefits. An additional theme - "Eating habits and health" - assesses subjects' beliefs about expected benefits of food and eating habits on health, disease prevention and protection, and quality of ageing. A preliminary validation was conducted with 444 subjects with balanced diet; non-balanced diet; and standard diet. The structure of the questionnaire was further determined using principal component analyses exploratory factor analyses, with confirmation of the sub-sections food behaviors, immediate benefits (pleasure, security, relaxation), direct short-term benefits (digestion and satiety, energy and psychology), and deferred long-term benefits (eating habits and health). Thirty-three subscales and 14 single items were further defined. Confirmatory analyses confirmed the structure, with overall moderate to excellent convergent and divergent validity and internal consistency reliability. The Well-BFQ is a unique, modular tool that comprehensively assesses the full picture of well-being related to food and eating habits in

  12. Increased Number of Circulating CD8/CD26 T Cells in the Blood of Duchenne Muscular Dystrophy Patients Is Associated with Augmented Binding of Adenosine Deaminase and Higher Muscular Strength Scores

    Full Text Available Duchenne muscular dystrophy (DMD is an X-linked disorder that leads to cardiac and skeletal myopathy. The complex immune activation in boys with DMD is incompletely understood. To better understand the contribution of the immune system into the progression of DMD, we performed a systematic characterization of immune cell subpopulations obtained from peripheral blood of DMD subjects and control donors. We found that the number of CD8 cells expressing CD26 (also known as adenosine deaminase complexing protein 2 was increased in DMD subjects compared to control. No differences, however, were found in the levels of circulating factors associated with pro-inflammatory activation of CD8/CD26 cells, such as tumor necrosis factor-α (TNFα, granzyme B, and interferon-γ (IFNγ. The number of CD8/CD26 cells correlated directly with quantitative muscle testing (QMT in DMD subjects. Since CD26 mediates binding of adenosine deaminase (ADA to the T cell surface, we tested ADA-binding capacity of CD8/CD26 cells and the activity of bound ADA. We found that mononuclear cells (MNC obtained from DMD subjects with an increased number of CD8/CD26 T cells had a greater capacity to bind ADA. In addition, these MNC demonstrated increased hydrolytic deamination of adenosine to inosine. Altogether, our data demonstrated that (1 an increased number of circulating CD8/CD26 T cells is associated with preservation of muscle strength in DMD subjects, and (2 CD8/CD26 T cells from DMD subjects mediated degradation of adenosine by adenosine deaminase. These results support a role for T cells in slowing the decline in skeletal muscle function, and a need for further investigation into contribution of CD8/CD26 T cells in the regulation of chronic inflammation associated with DMD.

    The purpose of the present study was to compare anomalous subjective experiences in patients with schizophrenia, bipolar disorder, and unipolar depression, in order to elucidate differences in subjective experiences and examine their potential clinical correlates in schizophrenia and mood disorders. The subjective experiences of 78 outpatients with schizophrenia (n=32), bipolar disorder (n=24) and unipolar depression (n=22), and 32 healthy controls were comprehensively assessed using the Frankfurt Complaint Questionnaire (FCQ). The FCQ total score was significantly higher in the schizophrenia and depression groups than in the healthy control group. There were no significant differences in the FCQ total or subscale scores among the schizophrenia, unipolar depression, and bipolar disorder groups. In the schizophrenia group, the Positive and Negative Syndrome Scale negative factor score was a significant negative predictor of the severity of subjective experiences assessed by the FCQ total score. Disruption of subjective experiences in patients with unipolar depression was associated with greater severity of depressive symptoms and younger age. In the bipolar disorder group, women reported more disruptions in subjective experience. Anomalous subjective experiences measured by the FCQ are not specific to schizophrenia, and the severity of these experiences in unipolar depression is substantially high. The finding of a dissimilar pattern of predictors of subjective experiences across different diagnostic groups suggests the complexity and variety of factors contributing to anomalous subjective experiences in schizophrenia and mood disorders.

    Full Text Available Brazil is today the world's largest broiler meat exporter; however, in order to keep this position, it must comply with welfare regulations while maintaining low production costs. Locomotion problems restrain bird movements, limiting their access to drinking and feeding equipment, and therefore their survival and productivity. The objective of this study was to evaluate locomotion deficiency in broiler chickens reared under stressful temperature conditions using three different sampling methods of birds from three different ages. The experiment consisted in determining the gait score of 28, 35, 42 and 49-day-old broilers using three different known gait scoring methods: M1, birds were randomly selected, enclosed in a circle, and then stimulated to walk out of the circle; M2, ten birds were randomly selected and gait scored; and M3, birds were randomly selected, enclosed in a circle, and then observed while walking away from the circle without stimulus to walking. Environmental temperature, relative humidity, and light intensity inside the poultry houses were recorded. No evidence of interaction between scoring method and age was found however, both method and age influenced gait score. Gait score was found to be lower at 28 days of age. The evaluation using the ten randomly selected birds within the house was the method that presented the less reliable results. Gait score results when birds were stimulated to walk were lower than when they were not simulated, independently of age. The gait scores obtained with the three tested methods and ages were higher than those considered acceptable. The highest frequency of normal gait score (0 represented 50% of the flock. These results may be related to heat stress during rearing. Average gait score incresead with average ambient temperature, relative humidity, and light intensity. The evaluation of gait score to detect locomotion problems of broilers under rearing conditions seems subjective and

    O.V. Lysenok

    2017-03-01

    Full Text Available The article proposes the borrower’s bank credit scoring model that is of particular relevance in an unstable world and Ukrainian financial markets. The essence of this integrated model is the consistent definition of indicators, which analyze the financial and economic situation and development of scoring that allows to calculate overall index, that is, the integral factor of credit scoring level of the bank to calculate which one uses the formed set of factors characterizing riskiness, profitability and liquidity of the banking institution. The author determines the factors according to their functional purpose; the former ones are divided into four groups: capital adequacy, loan portfolio quality, profitability and liquidity. Each group consists of four indicators; each indicator is assigned thresholds to determine the appropriate credit scoring level of the bank for one or another direction. The higher is the value of the integral factor, the more efficient and less risky is the financial and economic activity of banks and the higher is their credit scoring level. The study concludes that the proposed model for bank credit scoring differs with its transparency and clarity due to use in its implementation only public information. The disadvantages include the presence of the subjective factor in assigning a certain number of points based on expert and normative methods.

    There are numerous nasometric studies to date, including normative nasalance scores for various languages as well as nasometric differences in age, gender, race and region except the Korean language. In this regard, we sought to establish normative nasalance scores for Koreans. We created speech samples based on the everyday use of phonemes in the Korean language which were syntactically simple for children. In addition, we analysed nasometric features based on age and gender and confirmed test-retest reliability. The study included 108 children (54 girls and 54 boys, aged 7-11 years) and 108 adults (54 women and 54 men, aged 18-29 years) with normal articulation, resonance, voice and hearing. Nasometer II 6400 was used to measure the nasalance scores. The subjects read or repeated three speech stimuli, each consisting of 33, 36 and 24 syllables: (1) an oral passage devoid of nasal consonants, (2) an oro-nasal passage and (3) nasal sentences. For each stimulus, mean nasalance scores were obtained and gender or age dependence was analysed, using two-way analyses of variance. The mean nasalance scores for the oral passage, oro-nasal passage and nasal sentences were 11.69% (standard deviation (SD) 3.68), 34.04% (SD 4.88) and 63.72% (SD 6.07), respectively. Female speakers exhibited significantly higher nasalance scores than male speakers on the oro-nasal passage (p = 0.000) and nasal sentences (p = 0.004). Children exhibited significantly higher nasalance scores than adults on nasal sentences (p = 0.000). The nasalance scores in children and females were a little higher. Korean normative data will provide reference information in the evaluation and treatment of resonance problems. Copyright © 2013 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

    Subjective tinnitus is frequently seen in the general population. We investigated the personality traits in tinnitus and nontinnitus groups, both of which were nonpsychiatric. In this study, we evaluated 28 patients with subjective tinnitus and 28 subjects for a control group. In the analysis of psychiatric status, Minnesota Multiphasic Personality Inventory (MMPI) profiles were used. Psychasthenia was found to be higher in tinnitus patients of both sexes, whereas Hypochondriasis, Hysteria, Masculinity/Feminity, Psychasthenia, Schizophrenia, and Social Introversion scores were higher in females with tinnitus. In our research, it is thought that the experience of tinnitus may cause the psychological disturbance.

    The objectives of this study are threefold: 1) to examine the effect of frequency of head motion on the clinical dynamic visual acuity (DVA) score in subjects with unilateral vestibular hypofunction (UVH); 2) to compare DVA scores between subjects with UVH and subjects with a complete unilateral vestibular deficit; and 3) to establish whether a relationship exists between the extent of the vestibular deficit and the DVA score. Experimental study. Vestibular outpatient rehabilitation program. A convenience sample of 10 subjects with UVH. Dynamic visual acuity scores were recorded using 2 standard acuity charts: Snellen and E-chart. The DVA scores were obtained at slow (0.5 Hz), moderate (1 and 1.5 Hz), and fast (2.0 Hz) frequencies of head motion in the horizontal and the vertical planes. Percentage of caloric weakness was compared with DVA scores in each subject to test whether a relationship exists between the two. As the frequency of head motion increased, the number of UVH subjects with an abnormal DVA score increased. Subjects with an abnormal DVA score at 1 Hz had the same or higher score as the frequency of the head motion was increased. Spearman correlation analyses revealed low-correlation coefficients between percentage of vestibular paresis at the caloric test and DVA scores (horizontal direction: r = 0.31, p = 0.38 for Snellen chart and r = -0.33, p = 0.35 for the E-chart; vertical: r = 0.05, p = 0.91 for the Snellen chart and r = -0.28, p = 0.50 for the E-chart). Subjects with UVH manifest impaired DVA. The frequency of head motion has an impact on clinical DVA scores in UVH subjects.

    Cancer patients may require intensive care support for postoperative care, complications associated with underlying malignancy, or toxicities related to cancer therapy. The higher mortality rates found in this population than in the population of ICU patients without cancer may be attributable to confounding due to a higher prevalence of multiple organic dysfunctions at ICU admission in patients with malignancy; however, data regarding this hypothesis are scarce. Accordingly, we performed the present study to compare the crude and propensity score-matched mortality rates between adult subjects with and without cancer admitted to a mixed medical-surgical ICU. We conducted a retrospective analysis of a comprehensive longitudinal ICU database in a tertiary referral hospital in Southern Brazil. All adult subjects who were admitted to the ICU from January 2008 to December 2014 were evaluated. Crude and propensity score-matched all-cause 30-d mortality rates of critically ill subjects with cancer were compared with those of critically ill subjects without cancer. A total of 4,221 subjects were evaluated. The survival analysis revealed that the crude mortality rate was higher among subjects with cancer than among subjects without cancer (18.7% vs 10.2%, P < .001). However, after matching by propensity score, the 30-d mortality rates of subjects with and without cancer were similar (18.5% vs 15.2%, P = .17). The present study failed to show an association between malignancy and all-cause 30-d mortality rate in adult subjects admitted to a mixed medical-surgical ICU. The propensity score-matched analysis showed no evidence of excessive mortality due to cancer diagnosis. Copyright © 2017 by Daedalus Enterprises.

    The aim of this postmortem study was to compare, in Parkinson's disease subjects with and without bilateral subthalamic nucleus deep brain stimulation (STN-DBS), the loss of pigmented neurons within the substantia nigra and pathological alpha-synuclein density within the SN and other brain regions. PD subjects were identified from the Arizona Study of Aging and Neurodegenerative Disorders database (STN-DBS = 11, non-DBS = 156). Pigmented neuron loss scores within the substantia nigra as well as alpha-synuclein density scores within the substantia nigra and 9 other brain regions were compared, the latter individually and in summary as the Lewy body brain load score. DBS subjects had higher alpha-synuclein density scores within the substantia nigra, olfactory bulb, and locus ceruleus, as well as higher total Lewy body brain load scores when compared with non-DBS subjects. No differences in substantia nigra pigmented neuron loss scores were found. STN-DBS subjects tend to have higher alpha-synuclein density scores, but do not have a differential loss of substantia nigra pigmented neurons. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

    The aim was to establish normative nasalance values for Irish English-speaking adults. Thirty men and 30 women with normal resonance read aloud 16 sentences from the Irish nasality assessment protocol, the Zoo passage, and the Rainbow passage. The speech samples were recorded using the Nasometer II 6400. Results of a mixed between-within subjects ANOVA indicated no significant gender effect on nasalance scores. The speakers showed significantly higher nasalance scores for high-pressure consonant sentences than low-pressure consonant sentences, and for the Rainbow passage than total test sentences. There was no significant difference between high-pressure consonant sentences and the Zoo passage. Compared to previous studies, the Irish young adults had lower nasalance scores than Irish children and than young adults with North American dialects.

    Nasalance scores obtained from the Nasometer and the NasalView were compared for five different sentences. Vowel content was controlled in the design of the five stimulus sentences. One sentence was loaded with high-front vowels, one with high-back vowels, one with low-front vowels, one with low-back vowels, and one contained a mixture of vowel types. The subjects were 50 elementary school children ranging from kindergarten to sixth grade. Each subject was a native speaker of English, had no history of adenoidectomy, and was not currently enrolled in speech therapy services. The main outcome measures were the nasalance scores obtained from the Nasometer and the NasalView for each of the five sentences. There was a significant difference in the nasalance scores between the Nasometer and the NasalView for four of the five stimuli, but not all differences were in the same direction. For two stimuli, the Nasometer scores were significantly higher, and for two stimuli the NasalView scores were higher. Bivariate correlations between nasalance scores for individual stimuli were in the good range for the Nasometer but poor for the NasalView. Speech stimuli weighted with different vowel types are differentially affected by the different acoustical filtering used in the Nasometer versus the NasalView. Nasalance scores obtained with the NasalView were qualitatively and quantitatively different from those obtained with the Nasometer. This suggests that the two machines provide different information, and the scores are not interchangeable.

    The study aimed to examine the clinical correlates of polysubstance dependence. Seven hundred and fifty two substance-dependent subjects were interviewed with the Mini-International Neuropsychiatric Interview, the Brown-Goodwin Assessment for Lifetime History of Aggression (BGLHA), and the Hamilton Depression Rating Scale (HDRS). Subjects completed the Childhood Trauma Questionnaire (CTQ), Eysenck Personality Questionnaire (EPQ), and Barratt Impulsivity Scale (BIS). Subjects found to have polysubstance dependence were compared with subjects with monosubstance dependence. Polysubstance dependence was found in 48.3% of the subjects. Subjects with polysubstance dependence were significantly younger, more were separated/divorced and unemployed, and they had significantly higher CTQ scores for childhood emotional and physical neglect, higher EPQ psychoticism scores, higher BGLHA aggression scores, and higher BIS impulsivity scores. Significantly more of the polysubstance dependent subjects had attempted suicide, self-mutilated, and exhibited aggressive behavior. Significantly more monosubstance dependent subjects had an Axis I psychiatric disorder and they had higher HDRS depression scores. Polysubstance dependence is common among the groups studied and may be associated with certain socio-demographic, developmental, and personality factors.

    -contrast Cardiac-CT scan was performed to detect coronary artery calcification (CAC). RESULTS: Agreement of HeartScore risk groups with CAC groups was poor, but higher when applying the algorithm for the low-risk compared to the high-risk country model (agreement rate: 77% versus 63%, and weighted Kappa: 0.......22 versus 0.15). However, the number of subjects with severe coronary calcification (CAC score ≥400) increased in the low and intermediate HeartScore risk group from 78 to 147 participants (from 2.7 % to 4.2 %, p = 0.001), when estimating the risk based on the algorithm for low-risk countries.

    Hypnotizability is related to the Val158Met polymorphism of the COMT gene. The authors' aim was to find associations between candidate genes and subjective dimensions of hypnosis; 136 subjects participated in hypnosis and noninvasive DNA sampling. The phenomenological dimensions were tapped by the Archaic Involvement Measure (AIM), the Phenomenology of Consciousness Inventory (PCI), and the Dyadic Interactional Harmony Questionnaire (DIH). The main results were that the "Need of dependence" subscale of AIM was associated with the COMT genotypes. The GG subgroup showed higher scores, whereas AA had below average scores on the majority of the subjective measures. An association between the 5-HTTLPR polymorphism and the intimacy scores on the DIH was also evident. The effects are discussed in the social-psychobiological model of hypnosis.

  11. Greater robustness of second order statistics than higher order statistics algorithms to distortions of the mixing matrix in blind source separation of human EEG: implications for single-subject and group analyses.

    Science.gov (United States)

    Lio, Guillaume; Boulinguez, Philippe

    2013-02-15

    A mandatory assumption in blind source separation (BSS) of the human electroencephalogram (EEG) is that the mixing matrix remains invariant, i.e., that the sources, electrodes and geometry of the head do not change during the experiment. Actually, this is not often the case. For instance, it is common that some electrodes slightly move during EEG recording. This issue is even more critical for group independent component analysis (gICA), a method of growing interest, in which only one mixing matrix is estimated for several subjects. Indeed, because of interindividual anatomo-functional variability, this method violates the mandatory principle of invariance. Here, using simulated (experiments 1 and 2) and real (experiment 3) EEG data, we test how eleven current BSS algorithms undergo distortions of the mixing matrix. We show that this usual kind of perturbation creates non-Gaussian features that are virtually added to all sources, impairing the estimation of real higher order statistics (HOS) features of the actual sources by HOS algorithms (e.g., Ext-INFOMAX, FASTICA). HOS-based methods are likely to identify more components (with similar properties) than actual neurological sources, a problem frequently encountered by BSS users. In practice, the quality of the recovered signal and the efficiency of subsequent source localization are substantially impaired. Performing dimensionality reduction before applying HOS-based BSS does not seem to be a safe strategy to circumvent the problem. Second order statistics (SOS)-based BSS methods belonging to the less popular SOBI family class are much less sensitive to this bias. Copyright © 2012 Elsevier Inc. All rights reserved.

    To evaluate a comprehensive scoring system which combines clinical manifestations of Pierre Robin Sequence (PRS) including severity of breathing difficulties, body weight and preoperative Cormack-Lehane grade, for its correlation with perioperative PRS airway management decision. Forty PRS children were retrospectively recruited after surgery. Specialists examined all subjects and scored for clinical manifestations (1´ - 4´), weight gain (1´- 4´), dyspnea scores (1´- 4´), and Cormack-Lehane grade (1´- 4´). The correlation of the integrated scores and the necessity of endotracheal intubation or laryngeal mask application were analyzed. In addition, the score correlation with postoperative dyspnea and/or low pulse oxygen saturation (SPO2) levels after extubation was determined. In our study every individual patient had a score from 0´ to 16´, while the higher in the numbers represented higher risk of breathing difficulty. All patients with comprehensive scores 13 points required a laryngeal mask assisted airway management and were considered to have difficult airways. Dyspnea after extubation and postoperative low SPO2 occurred among patients who scored over 10 points. In PRS patients, preoperative weight gaining status and severity of dyspnea in combination with Cormack-Lehane classification provide a scoring system that could help to optimize airway management decisions such as endotracheal intubation or laryngeal mask airway placement and has the potential to predict postoperative dyspnea or low SPO2 levels.

    The aims of this study were to obtain normative nasalance scores for a normal Saudi population with different ages and genders, to develop nasometric Arabic speech materials, and to make cross-linguistic comparison. Participants included 219 normal Saudi native monolingual Arabic speakers of different ages. Subjects were classified into four groups according to age and gender. Subjects did not have any history of oral, nasal, or velopharyngeal abnormality. Arabic speech samples were developed to evaluate nasalance scores, which included syllables repetition, three oral sentences, three oro-nasal sentences, and three nasal sentences. Nasalance data were obtained using Nasometer II-6400. Normative nasalance values were determined. Significant differences between the male and female children groups were noticed in many parameters. Nasalance scores were higher in adults, with significant differences between all groups. Normative nasalance scores for Saudi Arabic speakers have been developed for both adults and children. The Arabic speech materials developed in this study appear to be easy to use and applicable for different age groups.

    The Apgar score provides an accepted and convenient method for reporting the status of the newborn infant immediately after birth and the response to resuscitation if needed. The Apgar score alone cannot be considered as evidence of, or a consequence of, asphyxia; does not predict individual neonatal mortality or neurologic outcome; and should not be used for that purpose. An Apgar score assigned during resuscitation is not equivalent to a score assigned to a spontaneously breathing infant. The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists encourage use of an expanded Apgar score reporting form that accounts for concurrent resuscitative interventions.

  1. INTEGRATIVE CLINICAL NUTRITION DIALYSIS SCORE (ICNDS FOR PREDICTION OF NUTRITIONAL RISK IN HEMODIALYSIS PATIENTS

    Directory of Open Access Journals (Sweden)

    Sara Blumberg

    2012-06-01

    Full Text Available The Integrative Clinical Nutrition Dialysis Score is a new quantitative method for identifying nutritional risk in hemodialysis patients. It is based on biochemical measures and weight change taken as a part of the patient’s monthly routine care and can be accomplished within a short time following completion of laboratory results. The Scoring result is a number between 0-100 given for each patient. A higher Score indicates a good nutritional status, a lower Score represents malnutrition. The Score identifies also a monthly change in nutritional status, and patients who should receive nutritional intervention. In 59 patients, Score results were found to be significantly correlated with nutrition evaluation by the Subjective Global Assessment taken within the same month. In 165 patients, baseline score emerged as a significant inverse predictor of mortality and hospitalization: each 1-unit increase in score reduced mortality risk by 7.1%, and reduced hospitalization risk by 6.5%. A 1- unit increase of slope of monthly scores reduced mortality risk by 23.6% and reduced hospitalization risk by 20.1%. A threshold of Score greater or equal to 75 reduced mortality by 64.2%. Patients were divided into four categories based on baseline score (above/equal or below a threshold of 75 and slope of monthly scores (smaller or larger/equal to 0. Worsening nutrition status over time as indicated by both score and slope, significantly increased death hazard. Results confirm that Integrative Clinical Nutrition Dialysis Score (ICNDS is a simple, useful prognostic tool to reflect hemodialysis patients nutrition status, and nutrition deterioration at its very commencement.

Twenty-eight subjects who had experienced maxillofacial trauma constituted the study cohort. Four commonly used systems were selected: New Injury Severity Score (NISS), Facial Injury Severity Scale (FISS), Maxillofacial Injury Severity Score (MFISS), and Maxillofacial Injury Severity Score (MISS). Each patient was graded using these 4 systems. From the experience of our trauma center, an expert scoring table was created. After the purpose and scheme of the study had been explained, 35 experts in maxillofacial surgery were invited to grade the injury of the 28 patients using the expert scoring table according to their clinical experience. The results of the 4 scoring systems and expert score were compared. The results of the 4 scoring systems and expert score demonstrated a normal distribution.

    Aims of this study were: a) to identify anthropometric variables correlated with gymnastic performance, and b) to predict performance scores from a combination of anthropometric dimensions. correlational analysis and a stepwise multiple regression were used. Subjects were participants at the 24th World Championships Artistic Gymnastics, Rotterdam, The Netherlands, in 1987. A total of 168 female gymnasts (mean age: 16.5 +/- 1.8 years) were investigated. Each gymnast participated in all events. An extensive battery of anthropometric dimensions was taken on each athlete. The somatotype was estimated. Skeletal maturation of the hand-wrist was assessed. Competition scores for the four individual gymnastic events (balance beam, floor exercise, vault, uneven bars) and a composite score for each gymnast were the dependent variables. Moderately high, significant correlations (p gymnastics performance scores, r varying from -0.38 to -0.60, for biceps skinfold and the score on balance beam, and for endomorphy and the total score, respectively. The correlations suggest that gymnasts with more subcutaneous fat and higher endomorphy have lower performance scores. About 32% to 45% of the variance in gymnastic performance scores could be explained by anthropometric dimensions and/or derived variables, but endomorphy and chronological age are the most important predictors. There is a relatively strong relationship between several anthropometric variables and gymnastic performance in a sample of elite female gymnasts, but the associations are not sufficiently high to predict performance scores on an individual basis.

    Background and Aims Numerous studies have demonstrated a relationship between Mediterranean Diet (MD) adherence and the prevention of cardiovascular diseases, cancer, and diabetes, etc. The study aim was to validate a novel instrument to measure MD adherence based on the consumption of food servings and food groups, and apply it in a female population from southern Spain and determining influential factors. Methods and Results The study included 1,155 women aged 12-83 yrs, classified as adolescents, adults, and over-60-yr-olds. All completed a validated semi-quantitative food frequency questionnaire (FFQ). The Mediterranean Dietary Serving Score (MDSS) is based on the latest update of the Mediterranean Diet Pyramid, using the recommended consumption frequency of foods and food groups; the MDSS ranges from 0 to 24. The discriminative power or correct subject classification capacity of the MDSS was analyzed with the Receiver Operating Characteristic (ROC) curve, using the MDS as reference method. Predictive factors for higher MDSS adherence were determined with a logistic regression model, adjusting for age. According to ROC curve analysis, MDSS evidenced a significant discriminative capacity between adherents and non-adherents to the MD pattern (optimal cutoff point=13.50; sensitivity=74%; specificity=48%). The mean MDSS was 12.45 (2.69) and was significantly higher with older age (pfoods and food groups per meal, day, and week. It may be useful in future nutritional education programs to prevent the early onset of chronic non-transmittable diseases in younger populations. PMID:26035442

    Adherence to a Mediterranean Diet appears to reduce the risk of cardiovascular disease, cancer, Alzheimer's disease, and Parkinson's disease, as well as the risk of death due to cardiovascular disease. No study has addressed the association between diagnostic subtype of stroke and its severity and adherence to a Mediterranean Diet in subjects with acute ischemic stroke. To evaluate the association between Mediterranean Diet adherence, TOAST subtype, and stroke severity by means of a retrospective study. The type of acute ischemic stroke was classified according to the TOAST criteria. All patients admitted to our ward with acute ischemic stroke completed a 137-item validated food-frequency questionnaire adapted to the Sicilian population. A scale indicating the degree of adherence to the traditional Mediterranean Diet was used (Me-Di score: range 0-9). 198 subjects with acute ischemic stroke and 100 control subjects without stroke. Stroke subjects had a lower mean Mediterranean Diet score compared to 100 controls without stroke. We observed a significant positive correlation between Me-Di score and SSS score, whereas we observed a negative relationship between Me-Di score and NIHSS and Rankin scores. Subjects with atherosclerotic (LAAS) stroke subtype had a lower mean Me-Di score compared to subjects with other subtypes. Multinomial logistic regression analysis in a simple model showed a negative relationship between MeDi score and LAAS subtype vs. lacunar subtype (and LAAS vs. cardio-embolic subtype). Patients with lower adherence to a Mediterranean Diet are more likely to have an atherosclerotic (LAAS) stroke, a worse clinical presentation of ischemic stroke at admission and a higher Rankin score at discharge.

    In environmental surveys, risk perception may be a source of bias when information on health outcomes is reported using questionnaires. Using the data from a survey carried out in the largest chipboard industrial district in Italy (Viadana, Mantova), we devised a score of health risk perception and described its determinants in an adult population. In 2006, 3697 parents of children were administered a questionnaire that included ratings on 7 environmental issues. Items dimensionality was studied by factor analysis. After testing equidistance across response options by homogeneity analysis, a risk perception score was devised by summing up item ratings. Factor analysis identified one latent factor, which we interpreted as health risk perception, that explained 65.4% of the variance of five items retained after scaling. The scale (range 0-10, mean ± SD 9.3 ± 1.9) had a good internal consistency (Cronbach's alpha 0.87). Most subjects (80.6%) expressed maximum risk perception (score = 10). Italian mothers showed significantly higher risk perception than foreign fathers. Risk perception was higher for parents of young children, and for older parents with a higher education, than for their counterparts. Actual distance to major roads was not associated with the score, while self-reported intense traffic and frequent air refreshing at home predicted higher risk perception. When investigating health effects of environmental hazards using questionnaires, care should be taken to reduce the possibility of awareness bias at the stage of study planning and data analysis. Including appropriate items in study questionnaires can be useful to derive a measure of health risk perception, which can help to identify confounding of association estimates by risk perception.

    The use of polygenic risk scores has become a practical translational approach to investigating the complex genetic architecture of schizophrenia, but the link between polygenic risk scores and pathophysiological components of this disorder has been the subject of limited research. We investigated in healthy volunteers whether schizophrenia polygenic risk score predicts hippocampal activity during simple memory encoding, which has been proposed as a risk-associated intermediate phenotype of schizophrenia. We analysed the relationship between polygenic risk scores and hippocampal activity in a discovery sample of 191 unrelated healthy volunteers from the USA and in two independent replication samples of 76 and 137 healthy unrelated participants from Europe and the USA, respectively. Polygenic risk scores for each individual were calculated as the sum of the imputation probability of reference alleles weighted by the natural log of odds ratio from the recent schizophrenia genome-wide association study. We examined hippocampal activity during simple memory encoding of novel visual stimuli assessed using blood oxygen level-dependent functional MRI. Polygenic risk scores were significantly associated with hippocampal activity in the discovery sample [P = 0.016, family-wise error (FWE) corrected within Anatomical Automatic Labeling (AAL) bilateral hippocampal-parahippocampal mask] and in both replication samples (P = 0.033, FWE corrected within AAL right posterior hippocampal-parahippocampal mask in Bari sample, and P = 0.002 uncorrected in the Duke Neurogenetics Study sample). The relationship between polygenic risk scores and hippocampal activity was consistently negative, i.e. lower hippocampal activity in individuals with higher polygenic risk scores, consistent with previous studies reporting decreased hippocampal-parahippocampal activity during declarative memory tasks in patients with schizophrenia and in their healthy siblings. Polygenic risk scores accounted for

    This study was designed for evaluating coagulation parameters and low APGAR scores in pregnancies with intrahepatic cholestasis of pregnancy (ICP) vs. normal control pregnancies. We carried out a prospective case-control study by enrolling 40 women with ICP at the third trimester of pregnancy and 40 pregnant women without ICP. Total bile acid levels (TBA), MPV, D-dimer, and umbilical artery systolic/diastolic ratio (UASDR) values were higher in women with ICP. Pregnancies complicated by low APGAR score exhibited significantly higher D-dimer levels than those of unimpaired fetal outcome in patients with ICP and control subjects. Levels of D-dimer were inversely correlated with 5'-Apgar score and positively associated with UASDR values in patients with ICP. Pregnancies that exhibited abnormal UASDR had higher total bile acid (TBA), D-dimer, MPV values and lesser 5'-Apgar score. In linear stepwise regression analyses, D-dimer independently and positively associated with UASDR, inversely associated with 5'-Apgar score in subjects with ICP; positively associated with mean platelet volume (MPV) values and inversely associated with 5'-Apgar score in all subjects. Patients with ICP had low-grade systemic coagulation and fibrinolytic activation as evidenced by elevated D-dimer, and also D-dimer is associated with lower APGAR scores in both ICP and all pregnancies. Increased D-dimer levels suggest that hematological parameters could be potentially used as indicators of risk factor for assessing low APGAR score in ICP.

    Full Text Available Background: The current article is aimed at evaluating speech recognition scores in hearing aid wearers to determine whether nonsense syllables are suitable speech materials to evaluate the effectiveness of their hearing aids. Method: Subjects were 60 children (15 males and 15 females with bilateral moderate and moderately severe sensorineural hearing impairment who were aged between 7.7-14 years old. Gain prescription was fitted by NAL method. Then speech evaluation was performed in a quiet place with and without hearing aid by using a list of 25 monosyllable words recorded on a tape. A list was prepared for the subjects to check in the correct response. The same method was used to obtain results for normal subjects. Results: The results revealed that the subjects using hearing aids achieved significantly higher SRS in comparison of not wearing it. Although the speech recognition ability was not compensated completely (the maximum score obtained was 60% it was also revealed that the syllable recognition ability in the less amplified frequencies were decreased. the SRS was very higher in normal subjects (with an average of 88%. Conclusion: It seems that Speech recognition score can prepare Audiologist with a more comprehensive method to evaluate the hearing aid benefits.

    The lod score method originated in a seminal article by Newton Morton in 1955. The method is broadly concerned with issues of power and the posterior probability of linkage, ensuring that a reported linkage has a high probability of being a true linkage. In addition, the method is sequential, so that pedigrees or lod curves may be combined from published reports to pool data for analysis. This approach has been remarkably successful for 50 years in identifying disease genes for Mendelian disorders. After discussing these issues, we consider the situation for complex disorders, where the maximum lod score (MLS) statistic shares some of the advantages of the traditional lod score approach but is limited by unknown power and the lack of sharing of the primary data needed to optimally combine analytic results. We may still learn from the lod score method as we explore new methods in molecular biology and genetic analysis to utilize the complete human DNA sequence and the cataloging of all human genes.

    With increasing use of immediate breast reconstruction (IBR), mastectomy skin flap necrosis (MSFN) is a clinical problem that deserves further study. We propose a validated scoring system to discriminate MSFN severity and standardize its assessment. Women who underwent skin-sparing (SSM) or nipple-sparing mastectomy (NSM) and IBR from November 2009 to October 2010 were studied retrospectively. A workgroup of breast and plastic surgeons scored postoperative photographs using the skin ischemia necrosis (SKIN) score to assess depth and surface area of MSFN. We evaluated correlation of the SKIN score with reoperation for MSFN and its reproducibility in an external sample of surgeons. We identified 106 subjects (175 operated breasts: 103 SSM, 72 NSM) who had ≥1 postoperative photograph within 60 days. SKIN scores correlated strongly with need for reoperation for MSFN, with an AUC of 0.96 for SSM and 0.89 for NSM. External scores agreed well with the gold standard scores for the breast mound photographs with weighted kappa values of 0.82 (depth), 0.56 (surface area), and 0.79 (composite score). The agreement was similar for the nipple-areolar complex photographs: 0.75 (depth), 0.63 (surface area), and 0.79 (composite score). A simple scoring system to assess the severity of MSFN is proposed, incorporating both depth and surface area of MSFN. The SKIN score correlates strongly with the need for reoperation to manage MSFN and is reproducible among breast and plastic surgeons.

    The purpose of this study was to collect nasalance scores for normal Korean-speaking children and adults and to determine whether age, vowel contexts, and stimulus length influence nasalance scores. Fifty-seven children aged 4-6 years and 17 adults participated in the study. Mean nasalance scores were obtained for eight sentences devoid of nasal consonants divided into the vowel/a/and/i/contexts; the sentences consisted of 4, 8, 16, and 31 syllables. All subjects were asked to repeat the speech stimuli twice after the examiner. The headset of the nasometer was replaced between the first and second recordings. An average value of the nasalance scores from the two recordings for each stimulus was calculated and used in the statistical analysis as a representative measure for each subject. Mean and standard deviations of nasalance scores were obtained for each speech stimulus and each age group. The statistical analysis indicated significant effects of age and vowel context and a significant interaction between age and the vowel context on nasalance scores. However, the effect of stimulus length on nasalance scores was not significant. All speakers had higher nasalance scores for the vowel/i/contexts than for the vowel/a/contexts. Adults had higher nasalance scores compared to children in both vowel contexts. These normal nasalance values from Korean-speaking children aged 4-6 years will provide important reference information for resonance assessment of children with cleft palate who have been considered for secondary palatal surgery. The results of the study suggest that subjects' age and the vowel content of speech stimuli should be carefully considered when interpreting the nasalance scores.

    Diagnostic criteria for postmenopausal osteoporosis using central dual-energy X-ray absorptiometry (DXA) T-scores have been widely accepted. The validity of these criteria for other populations, including premenopausal women and young men, has not been established. The International Society for Clinical Densitometry (ISCD) recommends using DXA Z-scores, not T-scores, for diagnosis in premenopausal women and men aged 20-49 yr, though studies supporting this position have not been published. We examined diagnostic agreement between DXA-generated T-scores and Z-scores in a cohort of men and women aged 20-49 yr, using 1994 World Health Organization and 2005 ISCD DXA criteria. Four thousand two hundred and seventy-five unique subjects were available for analysis. The agreement between DXA T-scores and Z-scores was moderate (Cohen\\'s kappa: 0.53-0.75). The use of Z-scores resulted in significantly fewer (McNemar\\'s p<0.001) subjects diagnosed with "osteopenia," "low bone mass for age," or "osteoporosis." Thirty-nine percent of Hologic (Hologic, Inc., Bedford, MA) subjects and 30% of Lunar (GE Lunar, GE Madison, WI) subjects diagnosed with "osteoporosis" by T-score were reclassified as either "normal" or "osteopenia" when their Z-score was used. Substitution of DXA Z-scores for T-scores results in significant diagnostic disagreement and significantly fewer persons being diagnosed with low bone mineral density.

    Many patients with rosacea do not seek medical care. The aim of this study was to find predictors for healthcare-seeking behaviour among patients with rosacea. The study subjects were 70 consecutive patients attending a dermatologist (seekers) and 56 subjects with rosacea symptoms selected randomly from among the working population (non-seekers). All subjects completed an Estonian Mood Scale questionnaire, a screening instrument for depressive symptoms, and evaluated their subjective disease perception on a visual analogue scale (VAS). Multivariate analysis showed that the independent predictors for healthcare-seeking behaviour were VAS scores >5 and the presence of advanced forms of rosacea. Higher mean VAS scores were not related to severity of rosacea, but were associated with the presence of depressive symptoms among seekers. In conclusion, healthcare-seeking behaviour is associated with higher subjective disease perception. The presence of depressive symptoms is not related to severity of the disease, but to the subjective disease perception of rosacea patients.

    Variable screening has emerged as a crucial first step in the analysis of high-throughput data, but existing procedures can be computationally cumbersome, difficult to justify theoretically, or inapplicable to certain types of analyses. Motivated by a high-dimensional censored quantile regression problem in multiple myeloma genomics, this article makes three contributions. First, we establish a score test-based screening framework, which is widely applicable, extremely computationally efficient, and relatively simple to justify. Secondly, we propose a resampling-based procedure for selecting the number of variables to retain after screening according to the principle of reproducibility. Finally, we propose a new iterative score test screening method which is closely related to sparse regression. In simulations we apply our methods to four different regression models and show that they can outperform existing procedures. We also apply score test screening to an analysis of gene expression data from multiple myeloma patients using a censored quantile regression model to identify high-risk genes. © 2014, The International Biometric Society.

    Existing patient self-reported shoulder scoring systems fail to express physicians' points of view, and understanding the wording can sometimes lead to confusion in Easterners. We sought to develop a valid, reliable, and responsive shoulder scoring system that combines the points of view of physicians and patients and is easily understood for worldwide applicability. Six steps were followed to develop the scale: (1) investigation, identification of a specific population, and patient and physician interviews; (2) item generation, according to existing shoulder scales, a literature review, and patient and physician interviews; (3) item reduction, by combining and adjusting items; (4) formatting of the questionnaire, designed using both subjective and objective scales, with a 100-point score range; (5) pretesting, to eliminate confusion and misunderstanding of items, and (6) preliminary evaluation. Pearson correlation coefficients were calculated to assess validity (compared with American Shoulder and Elbow Surgeons, Constant-Murley, and University of California, Los Angeles scores), intraclass correlation coefficients were calculated to assess reliability (with a 2-week test-retest interval), and the standardized response mean was calculated to assess responsiveness (comparing preoperative and postoperative scores in patients). The final scoring system was designed to have a 100-point score range, with higher scores indicating better function. It consisted of self-report assessment by patients (61 points in total) and objective assessment by physicians (39 points in total). Updated scales, including a night pain subscale, patient-physician satisfaction, and 2-dimensional visual analog scale tool, were incorporated in our system. Compared with the other 3 scoring systems (American Shoulder and Elbow Surgeons, Constant-Murley, and University of California, Los Angeles scores), the new scoring system has shown favorable validity, with a Pearson correlation coefficient

    Full Text Available Childhood trauma can lead to various psychological and cognitive symptoms. It has been demonstrated that high frequency electroencephalogram (EEG powers could be closely correlated with inattention. In this study, we explored the relationship between high frequency EEG powers, inattention, symptoms of adult attention deficit hyperactivity disorder (ADHD, and childhood traumatic experiences. A total of 157 healthy Korean adult volunteers were included and divided into two groups using the Childhood Trauma Questionnaire (CTQ score. The subjective inattention scores, ADHD scale, and anxiety and depression symptom were evaluated. EEG was recorded and quantitative band powers were analyzed. The results were as follows: (1 the high CTQ group showed significantly increased delta, beta1, beta2, beta3 and gamma, and significantly decreased low alpha power compared to the low CTQ group; (2 the high CTQ group had higher inattention score compared to the low CTQ group; (3 the high CTQ group had higher adult ADHD scores; (4 CTQ scores showed significant positive correlations with inattention scores, and adult ADHD scores; (5 unexpectedly, the inattention scores showed significant positive correlations with beta powers and a negative correlation with low alpha power; and (6 the moderated mediation model was confirmed: the depression fully mediated the path from state anxiety to inattention, and the CTQ significantly moderated the pathway between anxiety and depression. Our results show the possibility that childhood adversity may cause subjective inattention and adult ADHD symptoms. Depressive symptoms fully mediated the path from anxiety to inattention, especially in those who report severe childhood traumatic experiences.

    This study described the association of subjective well-being with combat exposure and social relationships among middle-aged and older Veteran men in the USA. The stress-buffering hypothesis, which predicts social relationships may moderate the association between combat exposure and subjective well-being, was also examined. Data from the 2008 Health and Retirement Study (N = 2961) were used to estimate logistic regression models, focusing on three measures of subjective well-being: depression, life satisfaction, and self-reported health. In the fully adjusted models, there were no statistically significant relationships between combat exposure and the three indicators of subjective well-being. However, compared to Veterans who had lower scores on the social relationship index, Veterans who had higher scores were less likely to be depressed and less likely to report poor or fair health. Veterans who had higher scores on the social relationships index reported higher levels of life satisfaction than those Veterans who had lower scores. There was no evidence for a social relationships buffering effect. The results of this study demonstrated that combat exposure did not have a long-term relationship with subjective well-being. Longitudinal research designs with more comprehensive indicators of combat exposure may help researchers better understand some of the underlying complexity of this relationship. Complementary research with samples of women Veterans, as well as samples of Hispanic, and non-Black, non-White Veterans, is also needed.

    To evaluate if the Apgar score remains pertinent in contemporary practice after more than 50 years of wide use, and to assess the value of the Apgar score in predicting infant survival, expanding from the neonatal to the post-neonatal period. The U.S. linked live birth and infant death dataset was used, which included 25,168,052 singleton births and 768,305 twin births. The outcome of interest was infant death within 1 year after birth. Cox proportional hazard-model was used to estimate risk ratio of infant mortality with different Apgar scores. Among births with a very low Apgar score at five minutes (1-3), the neonatal and post-neonatal mortality rates remained high until term (≥ 37 weeks). On the other hand, among births with a high Apgar score (≥7), neonatal and post-neonatal mortality rate decreased progressively with gestational age. Non-Hispanic White had a consistently higher neonatal mortality than non-Hispanic Black in both preterm and term births. However, for post-neonatal mortality, Black had significantly higher rate than White. The pattern of changes in neonatal and post-neonatal mortality by Apgar score in twin births is essentially the same as that in singleton births. The Apgar score system has continuing value for predicting neonatal and post-neonatal adverse outcomes in term as well as preterm infants, and is applicable to twins and in various race/ethnic groups.

    Universities in Thailand are preparing for Thailand's integration into the ASEAN Economic Community (AEC) by increasing the number of tests in English language. English language is not the native language of Thailand Differences in English language proficiency may affect scores among test-takers, even when subject knowledge among test-takers is comparable and may falsely represent the knowledge level of the test-taker. To study the impact of English language multiple choice test questions on test scores of medical students. The final examination of fourth-year medical students completing internal medicine rotation contains 120 multiple choice questions (MCQ). The languages used on the test are Thai and English at a ratio of 3:1. Individual scores of tests taken in both languages were collected and the effect of English language on MCQ was analyzed Individual MCQ scores were then compared with individual student English language proficiency and student grade point average (GPA). Two hundred ninety five fourth-year medical students were enrolled. The mean percentage of MCQ scores in Thai and English were significantly different (65.0 ± 8.4 and 56.5 ± 12.4, respectively, p language. Students were classified into six grade categories (A, B+, B, C+, C, and D+), which cumulatively measured total internal medicine rotation performance score plus final examination score. MCQ scores from Thai language examination were more closely correlated with total course grades than were the scores from English language examination (Spearman's correlation coefficient = 0.73 (p languages was higher in borderline students than in the excellent student group (11.2 ± 11.2 and 7.1 ± 8.2, respectively, p language MCQ examination scores were more highly associated with GPA than with English language proficiency. The use of English language multiple choice question test may decrease scores of the fourth-year internal medicine post-rotation final examination, especially those of borderline

    Full Text Available Numerous studies have demonstrated a relationship between Mediterranean Diet (MD adherence and the prevention of cardiovascular diseases, cancer, and diabetes, etc. The study aim was to validate a novel instrument to measure MD adherence based on the consumption of food servings and food groups, and apply it in a female population from southern Spain and determining influential factors.The study included 1,155 women aged 12-83 yrs, classified as adolescents, adults, and over-60-yr-olds. All completed a validated semi-quantitative food frequency questionnaire (FFQ. The Mediterranean Dietary Serving Score (MDSS is based on the latest update of the Mediterranean Diet Pyramid, using the recommended consumption frequency of foods and food groups; the MDSS ranges from 0 to 24. The discriminative power or correct subject classification capacity of the MDSS was analyzed with the Receiver Operating Characteristic (ROC curve, using the MDS as reference method. Predictive factors for higher MDSS adherence were determined with a logistic regression model, adjusting for age. According to ROC curve analysis, MDSS evidenced a significant discriminative capacity between adherents and non-adherents to the MD pattern (optimal cutoff point=13.50; sensitivity=74%; specificity=48%. The mean MDSS was 12.45 (2.69 and was significantly higher with older age (p<0.001. Logistic regression analysis showed highest MD adherence by over 60-year-olds with low BMI and no habit of eating between meals.The MDSS is an updated, easy, valid, and accurate instrument to assess MD adherence based on the consumption of foods and food groups per meal, day, and week. It may be useful in future nutritional education programs to prevent the early onset of chronic non-transmittable diseases in younger populations.

    To obtain normative data for nasalance scores in Middle Eastern English-speaking adult population. Cross-sectional study. A total of 102 subjects were recruited in the study, 26 were excluded, thus, 77 Middle Eastern English-speaking adults (mean age = 23.77 ± 4.295; 39 males, 38 females) with normal speech and no hearing problems participated in the study. Using Nasometer II 6450, nasalance scores were obtained for each participant's readings of 3 passages: Zoo and Rainbow passages and nasal sentences. Mean nasalance score, standard deviation and range. Mean nasalance scores for Zoo passage, Rainbow passage and nasal sentences were 25.21 ± 11.07, 34.04 ± 9.30 and 41.29 ± 9.87 respectively. Mean scores didn't differ significantly between males and females, though scores for the Zoo passage were slightly higher among males (26.51 ± 11.66) than females (23.87 ± 10.42). In within-session reliability testing, 86% of retests for all three passages fell within 5 nasalance points of the previous test. In across-session reliability testing, 93% of retests for all 3 passages were within 5 points of initial test. This study provides normative data for nasalance scores among Middle-Eastern adults, which can help make nasometer and determination of nasalance more clinically useful in this population.

    A pilot study designed as future randomised controlled trial was carried out to determine the effects of music on physiological responses and sedation scores in sedated, mechanically ventilated patients. Mechanically ventilated ICU patients, even when receiving intravenous sedatives, may experience stress and anxiety. One possible intervention to reduce stress and anxiety is listening to music. A randomised controlled trial design with repeated measures was used. Data were collected over a six-month period in 2006. Twenty subjects were randomly assigned to either the experimental or control group. Subjects in the experimental group listened to music three times for 30 minutes over two days; subjects in the control group undertook three 30 minute rest periods. Physiological effects of music on systolic, diastolic and mean arterial blood pressure and heart and respiratory rate were assessed. Sedation scores were also measured. Physiological parameters did not show a significant difference between the groups. Patients in the experimental group showed significantly higher Ramsay (sedation) scores than patients in the control group after the first session. The higher scores indicate that patients were less responsive to external stimuli. Our results suggest that listening to music leads to higher sedation scores in sedated, mechanically ventilated ICU patients. No significant decreases in physiological parameters were observed. Listening to music showed no negative changes in the condition of these patients. Future research should focus on the use of other measures, such as stress hormones, to assess stress in sedated, mechanically ventilated ICU patients. For the sedated, mechanically ventilated ICU patient, the benefit of music may lie in the associated (deeper) level of sedation that is achieved, which in turn may make the patient less susceptible to stress and anxiety.

    2016-07-01

    The changing complexity of maxillofacial fractures in recent years has created a situation where classical systems of classification of maxillofacial injuries fall short of defining trauma particularly that observed with high-velocity collisions where more than one region of the maxillofacial skeleton is affected. Trauma scoring systems designed specifically for the maxillofacial region are aimed to provide a more accurate assessment of the injury, its prognosis, the possible treatment outcomes, economics, length of hospital stay, and triage. The evolution and logic of such systems along with their merits and demerits are discussed. The author also proposes a new system to aid users in quickly and methodically choosing the system best suited to their needs without having to study a plethora of literature available in order to isolate their choice.

    Publishers of sheet music are generally reluctant in distributing their content via the Internet. Although online sheet music distribution's advantages are numerous the potential risk of Intellectual Property Rights (IPR) infringement, e.g. illegal online distributions, disables any innovation propensity. While active protection techniques only deter external risk factors, additional technology is necessary to adequately treat further risk factors. For several media types including music scores watermarking technology has been developed, which ebeds information in data by suitable data modifications. Furthermore, fingerprinting or perceptual hasing methods have been developed and are being applied especially for audio. These methods allow the identification of content without prior modifications. In this article we motivate the development of watermarking and fingerprinting technologies for sheet music. Outgoing from potential limitations of watermarking methods we explain why fingerprinting methods are important for sheet music and address potential applications. Finally we introduce a condept for fingerprinting of sheet music.

    The purpose of this project was to quantitatively test differences in subjective social status scores between non-pregnant and pregnant women to determine the role of subjective social status in birth weight variation between Mexico-born and US-born Mexican-American women. Six hundred low-income pregnant and non-pregnant Mexican immigrant and Mexican-American women in south Texas were surveyed for subjective social status, depression, perceived social stress, parity, and pregnancy intendedness. Psychosocial health variables, parity, and pregnancy intendedness were included due to their significant associations with low birth weight. Pregnant women had higher subjective social status scores than non-pregnant women. The difference in scores between non-pregnant and pregnant women was smaller in Mexican immigrant women than Mexican-American women. Pregnancy intendedness did not influence subjective social status in pregnant women of either sample, but having children (parity) in both samples was associated with higher subjective social status scores. Among Mexican-American women, community subjective social status was correlated with levels of depressive symptoms and perceived social stress. Subjective social status, depression, and perceived social stress were not correlated among Mexican immigrant women. Our results suggest that incorporation into the USA influences maternal mental health vis-à-vis changes in how women of reproductive age think about themselves and their gender roles in relation to others. Theoretically, our work supports mixed-method approaches to document how culture change as a result of immigration may impact maternal and infant health. Future research should test whether the effect of subjective social status on birth weight occurs when subjective social status does not correlate with depression or stress.

    To study the association of subjective memory complaints (SMC) with affective state and cognitive performance in elders. We studied community dwelling elderly persons with normal physical examination. Participants completed questionnaires regarding memory difficulties and lifestyle habits, the Geriatric Depression Scale (GDS) and the Spielberger State-Trait Anxiety Inventory (STAI). Depending on their answers to the question about their memory condition, participants were divided into complainers and non-complainers and to five groups according to their MMSE scores. These data have been compared to objective cognitive performance according to Mindstreams - a computerized neuropsychological battery. A logistic regression was performed to evaluate odds ratios (OR) and 95% confidence intervals (CI) for those factors, which were associated with SMС (dependent variable). Of 636 consecutive subjects (61% females), 507 participants (79.7%) had SMС. Presence of SMC was inversely correlated with MMSE scores, (r = -0.108; P for trend = 0.007). GDS and STAI scores were higher among subjects with SMC (OR = 1.23: CI 95%: 1.1-1.36 and OR = 1.03: CI 95%: 1.01-1.07, respectively). SMC did not correlate with objective cognitive performance measured by Mindstreams. Subjective memory complaints are associated with sub-syndromal depression and anxiety in healthy cognitively normal elders. © 2012 John Wiley & Sons A/S.

    The aims of this paper are to study the associations between objective and subjective sleep in pregnant women, to examine which specific aspects of women's sleep are associated with depressive and anxiety symptoms and to test the moderating role of depressive and anxiety symptoms in the relations between objective and subjective sleep. The sample included 148 pregnant women. Objective sleep was measured by actigraphy for five nights at the participants' home, and subjective sleep was measured with the Pittsburgh sleep quality index. Depressive symptoms were assessed with the Edinburgh postnatal depression scale and anxiety symptoms with the Beck anxiety inventory. Significant associations were found between the subjective sleep measures and the depressive and anxiety scores, but there were no significant associations between actigraphic sleep measures and the depressive and anxiety scores. Depressive and anxiety scores emerged as significant moderators of the links between objective and subjective sleep. The findings suggest that emotional distress (i.e., depressive and anxiety symptoms severity) during pregnancy is associated with subjective sleep disturbances but not with objective sleep disturbances. Importantly, only among women with higher levels of emotional distress was subjective sleep quality associated with objective sleep quality. These findings may suggest that women with higher levels of emotional distress are not necessarily biased in their perception of sleep quality. However, they may perceive fragmented sleep as more detrimental to their wellbeing.

    Introduction Many risk factors can affect depression and coronary disease, these including physiological and psychological risk factors (such as personality traits) Objectives Our objectives were to examine whether personality factors (The Five-Factor Model) can predict depression score in the depressed and coronary heart disease (CHD) individuals compared to that of healthy subjects. Materials and Methods To achieve the above objectives, 100 depressed (Mean=35.90 years, SD=10.59 years), and 100 CHD (Mean=46.42 years, SD=12.52 years), patients and 100 healthy subjects (Mean = 37.97 years, SD =12.49 years) were selected by convenience sampling method. To compare the three groups of participants, ANOVA test was used. Stepwise Multiple Regression Analysis was used to identify the variables that most closely predict the perceived stress and depression scores. Pearson’s Correlation Co-efficient was used to examine the correlation between variables. Results In Neuroticism, the CHD patients had significant highest scores, followed by depressed patients. The healthy group had the least scores. In case of Extraversion, Openness and Agreeableness, healthy participants had significant higher scores followed by the depressed and CHD patients. Only in conscientiousness factor, Depressive and CHD groups had statistically less scores compared to the healthy group. Also, high Neuroticism and Age, and low Extraversion were significant protective factors for depression Scores of CHD patients, while high Neuroticism and low Extraversion function as predictors in the depressed and healthy groups. Conclusion The effects of Neuroticism and Extraversion on depression have been reported as inconsistent across previous studies. This study indicates that, older CHD individuals with high Neuroticism and low Extraversion scores are more vulnerable for depression. PMID:26557596

    This study examined whether an online course would lead to increased knowledge about the medical issues volunteers encounter during a marathon. Health care professionals who volunteered to provide medical coverage for an annual marathon were eligible for the study. Demographic information about medical volunteers including profession, specialty, education level and number of marathons they had volunteered for was collected. A 15-question test about the most commonly encountered medical issues was created by the authors and administered before and after the volunteers took the online educational course and compared to a pilot study the previous year. Seventy-four subjects completed the pre-test. Those who participated in the pilot study last year (N = 15) had pre-test scores that were an average of 2.4 points higher than those who did not (mean ranks: pilot study = 51.6 vs. non-pilot = 33.9, p = 0.004). Of the 74 subjects who completed the pre-test, 54 also completed the post-test. The overall post-pre mean score difference was 3.8 ± 2.7 (t = 10.5 df = 53 p test scores. Testing also continued to show short-term improvement in post-course test scores, compared to pre-course test scores. In general, marathon medical volunteers who had no volunteer experience demonstrated greater improvement than those who had prior volunteer experience.

    Full Text Available It is generally easier to predict defaults accurately if a large data set (including defaults is available for estimating the prediction model. This puts not only small banks, which tend to have smaller data sets, at disadvantage. It can also pose a problem for large banks that began to collect their own historical data only recently, or banks that recently introduced a new rating system. We used a Bayesian methodology that enables banks with small data sets to improve their default probability. Another advantage of the Bayesian method is that it provides a natural way for dealing with structural differences between a bank’s internal data and additional, external data. In practice, the true scoring function may differ across the data sets, the small internal data set may contain information that is missing in the larger external data set, or the variables in the two data sets are not exactly the same but related. Bayesian method can handle such kind of problem.

    Score-based approaches for computing forensic likelihood ratios are becoming more prevalent in the forensic literature. When two items of evidential value are entangled via a scorefunction, several nuances arise when attempting to model the score behavior under the competing source-level propositions. Specific assumptions must be made in order to appropriately model the numerator and denominator probability distributions. This process is fairly straightforward for the numerator of the score-based likelihood ratio, entailing the generation of a database of scores obtained by pairing items of evidence from the same source. However, this process presents ambiguities for the denominator database generation - in particular, how best to generate a database of scores between two items of different sources. Many alternatives have appeared in the literature, three of which we will consider in detail. They differ in their approach to generating denominator databases, by pairing (1) the item of known source with randomly selected items from a relevant database; (2) the item of unknown source with randomly generated items from a relevant database; or (3) two randomly generated items. When the two items differ in type, perhaps one having higher information content, these three alternatives can produce very different denominator databases. While each of these alternatives has appeared in the literature, the decision of how to generate the denominator database is often made without calling attention to the subjective nature of this process. In this paper, we compare each of the three methods (and the resulting score-based likelihood ratios), which can be thought of as three distinct interpretations of the denominator proposition. Our goal in performing these comparisons is to illustrate the effect that subtle modifications of these propositions can have on inferences drawn from the evidence evaluation procedure. The study was performed using a data set composed of cursive writing

    Thrombolysis in myocardial infarction (TIMI) is a prognostic score developed for managing the high risk of cardiac events immediately after unstable angina and non-ST elevation myocardial infarction (UA/NSTEMI). In Asian populations that have a higher rate of bleeding complications, data about TIMI score are lacking. Using a Japanese multicenter registry, we investigated the impact of utilizing TIMI score in UA/NSTEMI patients, focusing on bleeding complications. The TIMI score was calculated for 587 patients who underwent percutaneous coronary intervention (PCI) for UA/NSTEMI (2008-2010). They were classified into low-risk (TIMI score 0-2, N = 268, 45.6 %), intermediate-risk (TIMI score 3-4, N = 264, 45.0 %) and high-risk (TIMI score 5-7, N = 55, 9.4 %) groups; patient characteristics for each group were statistically analyzed. The patients in the higher TIMI score group were older (p TIMI score was significantly associated with requirement of blood transfusion (low-risk, moderate-risk, and high-risk groups: 1.1, 4.2, and 7.3 %, respectively; p = 0.021), and the incidence of access site bleeding (1.1, 2.7, and 5.5 %, p = 0.112). The TIMI score might aid in subjectively quantifying the risk of in-hospital complication rates such as access site bleeding.

    This study was designed to evaluate neopterin levels and low Apgar scores in pregnancies with gestational diabetes mellitus (GDM) vs. normal control pregnancies. We carried out a cross-sectional study by enrolling 81 pregnant women with GDM and 38 pregnant women without GDM. Maternal and cord blood neopterin levels were higher in women with GDM. There was a significant positive association between fasting blood glucose levels and maternal serum neopterin levels. The results of 50-g oral glucose challenge tests revealed a correlation between maternal and cord neopterin levels. Pregnancies complicated by GDM exhibited lower fetal Apgar scores than those of control subjects. The levels of cord blood neopterin were inversely correlated with an fetal Apgar score of 1 min in patients with GDM. Patients with GDM had higher maternal and cord blood neopterin levels, and the cord blood neopterin levels are inversely associated with lower Apgar scores in women with GDM. The neopterin levels might be potential predictors of low fetal Apgar scores in women with GDM.

    The relationship between students' actual test scores and their self-estimated scores on the Hogan Personality Inventory (HPI; R. Hogan & J. Hogan, 1992), an omnibus personality questionnaire, was examined. Despite being given descriptive statistics and explanations of each of the dimensions measured, the students tended to overestimate their scores; yet all correlations between actual and estimated scores were positive and significant. Correlations between self-estimates and actual test scores were highest for sociability, ambition, and adjustment (r = .62 to r = .67). The results are discussed in terms of employers' use and abuse of personality assessment for job recruitment.

    Background The propensity score method has been underused in research concerning asthma epidemiology, which is useful for addressing covariate imbalance in observational studies. Objective: To examine the impact of neighborhood environment on asthma incidence by applying the propensity score method. Methods The study was designed as a retrospective cohort study. Study subjects were all children born in Rochester, Minn, between 1976 and 1979. Asthma status was previously determined by applying predetermined criteria. We applied the propensity score method to match children who lived in census tracts facing or not facing intersections with major highways or railroads. The propensity score of children living in a census tract facing intersections was formulated from a logistic regression model with 16 variables that may not be balanced between comparison groups. The Cox proportional hazard models were used in the matched samples to estimate hazard ratios of neighborhood environment and some other variables of interest and their corresponding 95% CIs. Results After matching with propensity scores, we found that children who lived in census tracts facing intersections with major highways or railroads had a higher risk of asthma (hazard ratios, 1.385–1.669 depending on the matching methods) compared with the matched counterparts who lived in census tracts not facing intersections with major highways or railroads. Conclusion Neighborhood environment may be an important risk factor in understanding the development of pediatric asthma. The propensity score method is a useful tool in addressing covariate imbalance and exploring for causal effect in studying asthma epidemiology. PMID:20236695

Aims: This study was aimed at assessing cardiac risk stratification by Framingham risk scoring (FRS and coronary coronary artery calcium score (CACS by noncontrast cardiac computed tomography in SCH. Study Design: Observational study. Subjects and Methods: We enrolled thirty treatment-naive SCH patients (aged 30–60 years with no serious concurrent medical conditions, thirty euthyroid (age, sex, and body mass index-matched controls, and ten healthy controls. All cases were evaluated for coronary artery calcium scoring and Framingham risk score. Statistical Analysis: Qualitative data were analyzed using the Chi-square test. In addition, demographics and CACS are summarized graphically or in a table. Results: SCH cases had higher thyroglobulin, while there was a trend toward an increase in total cholesterol, low-density lipoprotein (LDL, very LDL, and decrease in HDL levels. All participants had low-risk FRS (10-year FRS < 10%. The mean CACS in SCH was significantly higher than simple obese and healthy controls (47.17 vs. 2.67 vs. 0.00. Conclusion: This study suggests that SCH is an independent risk factor for coronary artery disease in apparently healthy controls. The risk of occult coronary artery disease is increased in SCH cases.

    Tablet scoring is a controversial but common practice used to adjust doses, facilitate drug intake, or lower the cost of drug treatment, especially in children and the elderly. The risks of tablet scoring are mainly related to inaccuracies in the resulting dose and stability problems. The aim of this article is to provide an overview of worldwide guidelines regarding tablet scoring. We found that regulatory health agencies in Mercosur countries as well as other South American countries do not have published standards addressing tablet splitting. Among the surveyed health agencies, the Food and Drug Administration (FDA) in the United States is the only one to present standards, ranging from splitting instructions to regulation of the manufacturing process. The concept of functional scoring implemented by the FDA has introduced some level of guarantee as to the ability of tablets to be split. In conclusion, technical and scientific bases are still insufficient to guide health rules on this subject, making the decision on scoring, in certain situations, random and highly risky to public health. The need for more detailed regulation is vital to ensure the safety of tablet medications.

    Given the extent, magnitude and functional significance of the neurocognitive deficits of schizophrenia, growing attention has been paid recently to patients' self-awareness of their own deficits. Thus far, the literature has shown either that patients fail to recognize their cognitive deficits or that the association between subjective and objective cognition is weak in schizophrenia. The reasons for this lack of consistency remain unexplained but may have to do, among others, with the influence of potential confounding clinical variables and the choice of the scale used to measure self-awareness of cognitive deficits. In the current study, we sought to examine the relationships between subjective and objective cognitive performance in schizophrenia, while controlling for the influence of sociodemographic and psychiatric variables. Eighty-two patients with a schizophrenia-spectrum disorder (DSM-IV criteria) were recruited. Patients' subjective cognitive complaints were evaluated with the Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS), the most frequently used scale to measure self-awareness of cognitive deficits in schizophrenia. Neurocognition was evaluated with working memory, planning and visual learning tasks taken from Cambridge Neuropsychological Tests Automated Battery. The Stroop Color-Word test was also administered. Psychiatric symptoms were evaluated with the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia. The relationships between subjective and objective cognition were evaluated with multivariate hierarchic linear regression analyses, taking into consideration potential confounders such as sociodemographic and psychiatric variables. Finally, a factor analysis of the SSTICS was performed. For the SSTICS total score, the regression analysis produced a model including two predictors, namely visual learning and Stoop interference performance, explaining a moderate portion of the variance

    Manifestations of mold allergy are classically associated with inhalation of mold spores leading to symptoms of asthma and other respiratory illnesses. It is largely unknown, however, whether ingestion of aeroallergenic molds, mold spores, or other fungi found in food can also elicit hypersensitivity reactions in mold-sensitive individuals. The aim of this study was to evaluate the association between exposure to molds by oral challenge and elicitation of symptoms in mold- versus nonmold-sensitive individuals. Thirty-four adult atopic subjects were randomized into mold-sensitive groups based on skin test reactivity by skin percutaneous testing (SPT) and/or intradermal (ID) testing to a mixed mold (MM) extract preparation. All subjects underwent a single-blinded, placebo-controlled food challenge to the MM preparation. A modified scoring system was used to grade the clinical severity of symptoms elicited by challenge. All subjects tolerated challenges to the maximal oral mold dose concentration. However, higher symptom scores after challenge were found in mold-sensitive subjects compared with nonmold-sensitive subjects (p = 0.01). When mold-sensitive subjects were compared based on SPT and/or ID reactivity, higher symptom scores and lower symptom-eliciting concentrations of mold were associated with the SPT reactive subgroup compared with the subgroup with ID reactivity alone. In summary, based on our challenge results and scoring model, mold-sensitive subjects compared with nonmold-sensitive subjects experienced cumulatively higher symptom scores after oral challenge to an MM extract preparation. Future studies are warranted to confirm whether ingestion of aeroallergenic molds in food may be another contributor to symptoms in mold-sensitive individuals.

    The effects of the affectionless control (AC) parenting style on personality traits were studied in 414 Japanese healthy subjects. Perceived parental rearing was assessed by the Parental Bonding Instrument, which comprises care and protection factors, and personality traits were assessed by the Temperament and Character Inventory, which has seven dimensions. Parental rearing was classified into four types, i.e., optimal parenting (high care/low protection), affectionate constraint (high care/high protection), neglectful parenting (low care/low protection), and AC (low care/high protection). Males with maternal AC showed significantly higher harm avoidance (HA) scores and lower scores of persistence and cooperativeness than those with maternal optimal parenting. Females with maternal AC showed significantly higher HA scores and lower self-directedness scores than those with maternal optimal parenting. Paternal AC was not significantly related to any personality score. In females, the interaction between paternal rearing and maternal rearing was significant; the effect of maternal AC on HA scores was strongest when combined with paternal neglectful parenting. The present study suggests that the AC type parenting by mothers is associated with specific personality traits, especially high HA, in healthy subjects.

    Full Text Available Purpose Although there have been studies emphasizing the re-education of North Korean (NK doctors for post-unification of the Korean Peninsula, study on the content and scope of such re-education has yet to be conducted. Researchers intended to set the content and scope of re-education by a comparative analysis for the scores of the preliminary examination, which is comparable to the Korean Medical Licensing Examination (KMLE. Methods The scores of the first and second preliminary exams were analyzed by subject using the Wilcoxon signed rank test. The passing status of the group of NK doctors for KMLE in recent 3 years were investigated. The multiple-choice-question (MCQ items of which difficulty indexes of NK doctors were lower than those of South Korean (SK medical students by two times of the standard deviation of the scores of SK medical students were selected to investigate the relevant reasons. Results The average scores of nearly all subjects were improved in the second exam compared with the first exam. The passing rate of the group of NK doctors was 75%. The number of MCQ items of which difficulty indexes of NK doctors were lower than those of SK medical students was 51 (6.38%. NK doctors’ lack of understandings for Diagnostic Techniques and Procedures, Therapeutics, Prenatal Care, and Managed Care Programs was suggested as the possible reason. Conclusion The education of integrated courses focusing on Diagnostic Techniques and Procedures and Therapeutics, and apprenticeship-style training for clinical practice of core subjects are needed. Special lectures on the Preventive Medicine are likely to be required also.

    In the United Kingdom medical students are selected predominantly on their academic merit. Their academic achievement marks are equated via the tariff point score structure administered by the Universities and Colleges Admissions Service (UCAS). We studied the applicant databases for 1998-2003 for one English medical school to determine the factors that predict high tariff point scores. Complete demographic data and relative socio-economic status, educational institution attended and tariff point score was available for 8997 UK applicants aged 21 years or younger to the 5-year Bachelor of Medicine/Bachelor of Surgery (BM BS) course at Nottingham University medical school (and partially complete data for a further 1891 applicants). The data were subjected to standard univariate and multivariate analyses and to path analysis. In these samples, the independent predictors of a high tariff point score were being younger and male. The effect sizes were small, although significant. Higher tariff point scores were achieved by those from households less materially disadvantaged. Ethnicity was also a predictor with white, Chinese and those of mixed ethnic origin achieving higher tariff point scores than those from other groups. Finally, the type of school attended predicted academic achievement with applicants from further education colleges, independent schools and grant-maintained schools achieving higher tariff point scores. Notwithstanding the relatively homogeneous (predominantly young, white, high academic achievers) applicant pool to a single UK medical school we identified consistent significant predictors of high tariff point scores. As high tariff point scores are still the major entry criterion to UK medical schools, our findings will be of value in informing policy decisions concerning 'widening access' schemes being established at government request.

    Animal research has outlined a vulnerability trait to drug dependence like behavior. The behavioral characteristic of this vulnerability is hyperactivity in response to a novel environment of which sensation seeking (SS) has been suggested as a possible equivalent in humans. If this is the case, SS should be more frequent in drug dependent and risky sports practicing subjects then controls. The objective of this study was to determine if opioid dependent subjects (ODS) and regular paragliders (RP) would be more SS then normal controls. Cross sectional study. Three groups of 34 individuals (total 102) matched for age and sex were selected from ODS seeking treatment, a paragliding club, and a college staff. Global and sub-scores of the Zuckerman sensation seeking scale (SSS). Non parametric statistics (Kruskal Wallis and Wilcoxon 2-Sample Tests) were used given the non-normal distribution of SSS scores in the ODS and RP groups. Significant differences were found across the three groups for the Thrill and Adventure Seeking (TAS) (P = 0.001), dishinibition (Dis) (P = 0.0003) and total score (P = 0.001). ODS and RP scored significantly higher than controls on two (Dis and the TAS scales). RP also scored significantly higher on the Boredom Susceptibility (BS) scale (P = 0.04). Our results show that RP and ODS differ from controls and have some similarities based on the SSS. In this study, the ODS and the RP could express different forms of a general tendency to seek intense and abrupt sensations through various behaviors. Our results in humans are in favor of the hypothesis that the behavioral trait of vulnerability to drug dependence behavior is expressed through SS. Copyright 2002 Elsevier Science Ireland Ltd.

    Prediabetes is associated with an increased risk of cardiovascular disease (CVD). While the association of impaired glucose tolerance with CVD has been shown in many studies, the relationship between impaired fasting glucose (IFG) and CVD remains unclear. The purpose of this study was to compare the coronary artery calcium (CAC) scores of participants with normal fasting glucose versus those with IFG, according to fasting plasma glucose (FPG) levels, and to assess whether differences in CAC scores were independent of important confounders. Retrospective study. Health Promotion Center of the University Hospital (Gyeonggi-do, South Korea), during the period 2010-2014. Participants were enrolled from the general population who visited for a medical check-up. CAC was assessed in asymptomatic individuals by multidetector computed tomography. Anthropometric parameters and metabolic profiles were also recorded. Subjects were divided into four fasting glucose groups. Participants with a history of CVD or diabetes mellitus were excluded. Correlation between FPG and CAC scores, CAC score categories, and association between CAC score and FPG categories. Of 1112 participants, 346 (34.2%) had a CAC score > 0. FPG values in the IFG patients were positively but weakly correlated with CAC scores (r=0.099, P=.001). The incidence of CAC differed according to FPG level (P =110 mg/dL had a significantly higher risk of CAC than did subjects with normal fasting glucose (110.

    To compare the incidence of polycythemia in newborns of women with hypertensive disorders in pregnancy (HDP) with those of normotensive mothers, to determine the incidence of perinatal stress using Apgar scores and to correlate hematocrit with Apgar scores in these newborn. This was a hospital-based comparative study conducted in the University of Port Harcourt Teaching Hospital, Nigeria. Apgar scores of 200 newborns- 100 from mothers with HDP (case group) and 100 from normotensive mothers (control group)- were taken at 1st and 5th minute of birth and cord blood samples collected to determine hematocrit. The subjects were categorized into polycythemic and non polycythemic using a hematocrit ≥65%. Eight percent of newborns of women with HDP had polycythemia while none of the controls did. Apgar scores in the case group with and without polycythemia at one-minute were 4.1±1.8 and 6.6±2.1, respectively and at 5 minutes were 6.9±1.7 and 8.5±1.4 respectively. Hematocrit correlated positively with Apgar scores (both at one and five minutes) in cases without polycythemia (r = 0.221, p = 0.034 and r = 0.255, p = 0.014). Hematocrit of polycythemic newborns did not correlate with Apgar scores (r = -0.287, p = 0.491 and r = -0.436, p = 0.281). The incidence of polycythemia is significantly higher in newborns of women with HDP and these polycythemic neonates had a significantly higher incidence of birth asphyxia. Therefore, birth outcome as determined by Apgar score is influenced by hematocrit.

    The objective of this study was to evaluate test-retest nasalance score variability in subjects with hypernasal resonance. Two groups of subjects with hypernasal speech recited both the Turtle Passage and the Mouse Passage two times each. For one group, the Nasometer headgear was not changed between repetitions of each stimulus (NCHG; n = 17); and for the other group, the headgear was changed between repetitions (CHG; n = 18). Three subjects in the CHG group would not recite the Mouse Passage two times. The subjects were 35 patients with hypernasal speech followed by a cleft palate team. The outcome measures were the four nasalance scores obtained for each subject. There was no significant difference between first and second repetitions for either stimulus in either the NCHG group or in the CHG group. Cumulative frequency tables showed that for the Turtle Passage-NCHG condition, 15 of the 17 (88%) repeated nasalance scores were within 5 nasalance points of each other. For the CHG condition, however, only 9 of 18 (50%) repeated nasalance scores were within 5 points. For the Mouse Passage-NCHG condition, 15 of the 17 (88%) repeated nasalance scores were within 5 points. For the CHG condition, however, only 11 of 15 (73%) repeated scores were within 5 points. Test-retest variability was greater in a population of hypernasal patients than that reported in other studies for normal speakers, and headgear change increased test-retest variability.

    This retrospective study compared the influence of perceived sports involvement on lower extremity neuromuscular adaptations during single-leg countermovement jumping (CMJ), perceived knee function and internal health locus of control (HLOC) scores at a minimum 2-year post-anterior cruciate ligament reconstruction. The hypothesis was that subjects with higher-level sports involvement would display significant differences compared to subjects with lower-level sports involvement. Uninvolved and involved lower extremity EMG amplitude (1,000 Hz), vertical ground reaction force (VGRF) (500 Hz) and kinematic (60 Hz) displacement differences were determined during single-leg CMJ. These data and International Knee Documentation Committee subjective knee survey scores, Multidimensional Health Locus of Control Survey internal HLOC subscale scores and sports activity characteristics were compared by sports involvement level. Subjects that regarded themselves as only sporting sometimes (Group 3, n = 26) had lower IKDC survey and internal HLOC scores, were more likely to decrease sports activities by two intensity levels than highly competitive (Group 1, n = 20) and well-trained/frequently sporting (Group 2, n = 24) subjects, and had greater peak landing VGRF differences suggesting decreased involved lower extremity loading compared to Group 2. During propulsion, Group 1 had greater gluteus maximus (GM) and gastrocnemius (G) EMG differences than Groups 2 and 3. Groups 1 and 2 had decreased vastus medialis (VM) EMG differences during propulsion than Group 3. During landing, Group 1 had greater GM and G EMG differences than Group 3. Subjects with higher-level sports involvement up-regulated involved lower extremity GM and G activation and down-regulated VM activation. This adaptation may enable continued higher-level sports participation while minimizing knee joint forces. Perceived higher-level sports involvement was related to neuromuscular adaptations, better subjective knee

    To evaluate the association between Dizziness Handicap Inventory-Screening version (DHI-S) score and spatiotemporal gait parameters using SoleSound, a newly developed, inexpensive, portable footwear-based gait analysis system. Cross-sectional. One hundred eighteen patients recruited from otology clinic. Subjects completed the DHI-S survey and four uninterrupted walking laps wearing SoleSound instrumented footwear on a hard, flat surface for 100 m. For each subject, mean and coefficient of variation (CV) of stride length, cadence, walking speed, foot-ground clearance, double-support time, swing period, and stance-to-swing were computed by considering 40 strides of steady-state walking within each lap. Linear regression models were employed to study correlations between these variables and DHI-S scores after adjusting for age, sex, and race/ethnicity. Patients with higher DHI-S score took shorter steps and less steps per minute (-0.017 m and -1.1 steps/min per every four-point increase in DHI-S score, p handicap, as assessed with DHI-S, is associated with deterioration in measurable gait parameters independent of age.

    The association between myopia and cognitive dysfunction among elderly adults was assessed by applying a Propensity Score Matching (PSM) approach. This is a statistical method which allows investigators to estimate causal treatment effects using observational or nonrandomised data. The study was designed as a community-based cross-sectional study based on a Chinese cohort aged 60 years or older in China. Objective refraction was measured using an autorefractor and subjective refraction was used to refine vision, using the results of the objective refraction as the starting point. Myopia was defined as a spherical equivalent value of less than -0.50 dioptre (D) in the right eye. The Abbreviated Mental Test (AMT) was used for cognitive assessment. The propensity scores for myopia were formulated using 13 potential confounders. We matched the propensity scores for subjects with and without myopia within a caliper of 0.01 of logit function of propensity scores. About 4123 elderly adults who successfully completed the AMT were included in this analysis. The odds ratio (OR) of cognitive dysfunction for myopia before matching was 1.98 (95% confidence interval [CI] 1.61, 2.44; p Myopia was associated with a higher prevalence of cognitive dysfunction among elderly Chinese aged 60 years or older in China. The PSM approach may be a useful method to address selection bias in observational studies when randomised trials cannot ethically be conducted. © 2015 The Authors Ophthalmic & Physiological Optics © 2015 The College of Optometrists.

    The American Academy of Pediatrics recommends that test scores should be corrected for prematurity up to 3 years of age, but this practice varies greatly in both clinical and research settings. The aim of this study was to contrast the effects of using chronological age and those of using corrected age on measures of cognitive outcome across childhood. A theoretical model was constructed using norms from the Bayley Scales of Infant and Toddler Development, Third Edition; the Wechsler Preschool and Primary Scale of Intelligence, Third Edition Australian; and the Wechsler Intelligence Scales for Children, Fourth Edition Australian. Baseline scores representing different levels of functioning (70, below average; 85, borderline; and 100, average) were recalculated using the normative data for ages 6 months to 16 years to account for 1, 2, 3 and 4 months of prematurity. The model created depicted the difference in standardised scores between chronological and corrected age. Compared with scores corrected for prematurity, the absolute reduction in scores using chronological age was greater for increasing degree of prematurity, younger ages at assessment and higher baseline scores and was substantial even beyond 3 years of age. However, the pattern was erratic, with considerable fluctuation evident across different ages and baseline scores. Chronological age results in a lowering of scores at all ages for preterm-born subjects that is greater in the first few years and in those born at earlier gestational ages. Whether or not to correct for prematurity depends upon the context of the assessment. © 2014 The Authors.

    Males and females have different temperaments. In individuals with gender dysphoria (GD) there is marked incongruence between a person׳s expressed/experienced gender and their biological sex. The present study aimed to investigate the most common affective temperaments in individuals with female-to-male (FtM) GD. We performed a prospective and comparative study investigating affective temperaments in subjects with FtM GD. Eighty subjects with FtM GD and 68 female controls were enrolled. The Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) was completed by all participants. TEMPS-A scores were significantly higher in subjects with FtM GD for hyperthymic temperament (p≤0.001), whereas depressive (p≤0.001), anxious (p≤0.001), and cyclothymic (p=0.028) temperament scores were significantly higher in female controls. The study was limited by the lack of male-to-female subjects and male controls. The results of our study indicate that individuals with FtM GD have significantly higher scores of hyperthymic temperament, measured by TEMPS-A. Biological basis underlying the development of gender identity independent from the biological sex might be related with affective temperaments. Copyright © 2015 Elsevier B.V. All rights reserved.

    The systematic implementation of evidence-based practice through the use of guidelines, checklists, and protocols mitigates the risks associated with mechanical ventilation, yet variation in practice remains prevalent. Recent advances in software and hardware have allowed for the development and deployment of an enhanced visualization tool that identifies mechanical ventilation goal variance. Our aim was to assess the utility of daily goal establishment and a computer-aided visualization of variance. This study was composed of 3 phases: a retrospective observational phase (baseline) followed by 2 prospective sequential interventions. Phase I intervention comprised daily goal establishment of mechanical ventilation. Phase II intervention was the setting and monitoring of daily goals of mechanical ventilation with a web-based data visualization system (T3). A single score of mechanical ventilation was developed to evaluate the outcome. The baseline phase evaluated 130 subjects, phase I enrolled 31 subjects, and phase II enrolled 36 subjects. There were no differences in demographic characteristics between cohorts. A total of 171 verbalizations of goals of mechanical ventilation were completed in phase I. The use of T3 increased by 87% from phase I. Mechanical ventilation score improved by 8.4% in phase I and 11.3% in phase II from baseline ( P = .032). The largest effect was in the low risk V T category, with a 40.3% improvement from baseline in phase I, which was maintained at 39% improvement from baseline in phase II ( P = .01). mechanical ventilation score was 9% higher on average in those who survived. Daily goal formation and computer-enhanced visualization of mechanical ventilation variance were associated with an improvement in goal attainment by evidence of an improved mechanical ventilation score. Further research is needed to determine whether improvements in mechanical ventilation score through a targeted, process-oriented intervention will lead to

    Happiness is a subjective experience that is an ultimate goal for humans. Psychological studies have shown that subjective happiness can be measured reliably and consists of emotional and cognitive components. However, the neural substrates of subjective happiness remain unclear. To investigate this issue, we used structural magnetic resonance imaging and questionnaires that assessed subjective happiness, the intensity of positive and negative emotional experiences, and purpose in life. We found a positive relationship between the subjective happiness score and gray matter volume in the right precuneus. Moreover, the same region showed an association with the combined positive and negative emotional intensity and purpose in life scores. Our findings suggest that the precuneus mediates subjective happiness by integrating the emotional and cognitive components of happiness.

    While peptides carrying PTMs are routinely identified in gel-free MS, the localization of the PTMs onto the peptide sequences remains challenging. Search engine scores of secondary peptide matches have been used in different approaches in order to infer the quality of site inference, by penalizing the localization whenever the search engine similarly scored two candidate peptides with different site assignments. In the present work, we show how the estimation of posterior error probabilities for peptide candidates allows the estimation of a PTM score called the D-score, for multiple search engine studies. We demonstrate the applicability of this score to three popular search engines: Mascot, OMSSA, and X!Tandem, and evaluate its performance using an already published high resolution data set of synthetic phosphopeptides. For those peptides with phosphorylation site inference uncertainty, the number of spectrum matches with correctly localized phosphorylation increased by up to 25.7% when compared to using Mascot alone, although the actual increase depended on the fragmentation method used. Since this method relies only on search engine scores, it can be readily applied to the scoring of the localization of virtually any modification at no additional experimental or in silico cost. © 2013 WILEY-VCH Verlag GmbH & Co.

    In this paper we investigate the behavior of the conditional probability Prob(U > u|V > v) of two records coming from students of an undergraduate course, where U is the score of calculus I, scaled in [0, 1] and V is the score of physics scaled in [0, 1], the physics subject is part of the admission test of the university. For purposes of comparison, we consider two different undergraduate courses, electrical engineering and mechanical engineering, during nine years, from 2003 to 2011. Through a Bayesian perspective we estimate Prob(U > u|V > v) year by year and course by course. We conclude that U is right tail increasing in V, in both courses and for all the years. Moreover, over these nine years, we observe different ranges of variability for the estimated probabilities of electrical engineering when compared to the estimated probabilities of mechanical engineering.

    To determine the prevalence and degree of CAC (coronary artery calcification) in appearently healthy middle-aged Koreans, and the relation of CAC to risk factors for atherosclerosis. A total of 289 apparently healthy personnel at Yonsei University (male: 170, female:119, age: mean(SD=54.9{+-}7.1 years)) underwent EBT (electron bean tomography). The risk factors for athero-sclerosis, which included diabetes mellitus, hypertension, smoking, a family history of precocious onset, obesity, hyperlipidemia, and high intraperitoneal fat, were scrutinized. One hundred and sixty-eight subjects (58%) had at least one risk factor. The CAC score was calculated for all subjects and for each coronary artery separately and was then analyzed by age and sex and in relation to the risk factors. The prevalence of CAC was 40% in men and 18.5% in women (mean score:29.7 vs. 9.9). The number of individuals who had one, two, or more than two risk factors was 141,41, and 19, respectively. The number of risk factors and the prevalence and score of CAC were significantly correlated (p=0.01, 0.02 respectively). The number of individuals with no risk factor, with without CAC, was 58(20.1%) and 103(35.6%), respectively, while the number with some risk factor, with or without CAC, was 38(13.1%) and 90(31.1%), respectively. The CAC score was significantly higher in the presence of hypertension, low HDL, or obesity(p=0.001, 0.049, and 0.068, respectively). Smoking appeared to have a borderline effect on the calcium score(p=0.118). This study should provide useful information for interpreting CAC scores and establishing a treatment strategy for Koreans. The comparison of our results with other studies will enable a better understanding of the process and risk factors of atherosclerosis in Koreans.

  7. Extension of the lod score: the mod score.

    In 1955 Morton proposed the lod score method both for testing linkage between loci and for estimating the recombination fraction between them. If a disease is controlled by a gene at one of these loci, the lod score computation requires the prior specification of an underlying model that assigns the probabilities of genotypes from the observed phenotypes. To address the case of linkage studies for diseases with unknown mode of inheritance, we suggested (Clerget-Darpoux et al., 1986) extending the lod score function to a so-called mod score function. In this function, the variables are both the recombination fraction and the disease model parameters. Maximizing the mod score function over all these parameters amounts to maximizing the probability of marker data conditional on the disease status. Under the absence of linkage, the mod score conforms to a chi-square distribution, with extra degrees of freedom in comparison to the lod score function (MacLean et al., 1993). The mod score is asymptotically maximum for the true disease model (Clerget-Darpoux and Bonaïti-Pellié, 1992; Hodge and Elston, 1994). Consequently, the power to detect linkage through mod score will be highest when the space of models where the maximization is performed includes the true model. On the other hand, one must avoid overparametrization of the model space. For example, when the approach is applied to affected sibpairs, only two constrained disease model parameters should be used (Knapp et al., 1994) for the mod score maximization. It is also important to emphasize the existence of a strong correlation between the disease gene location and the disease model. Consequently, there is poor resolution of the location of the susceptibility locus when the disease model at this locus is unknown. Of course, this is true regardless of the statistics used. The mod score may also be applied in a candidate gene strategy to model the potential effect of this gene in the disease. Since, however, it

    The occurrence of Asian dust events is a frequent problem, with associated health issues throughout Northeast Asia. However, the effects of Asian dust on human health are not well known in Japan. The authors evaluated the association between daily symptoms and dust events in Yonago, Japan. The subjects were 54 healthy individuals who were distributed survey sheets on nasopharyngeal, ocular, respiratory, and skin symptoms, which were quantified in February 2009. The authors investigated the symptoms of the subjects on Asian dust days and control days, and compared the symptom scores with measures of suspended particulate matter (SPM), which is the indicator of Asian dust. The scores for symptoms were significantly higher on Asian dust days than on control days (p=.020). The skin symptom scores were positively correlated with the SPM level (pAsian dust influence the symptoms of healthy subjects, although the symptoms are not severe.

    1995-12-01

    This study assesses subjective effects of traffic noise and the mediator role that negative statements about the noise and about oneself play. Eighty-four students underwent two 15-minute presentations of high intensity traffic noise, with and without negative statements. The potential effect of the negative statements was enhanced by the use of instructions concerning the expectation of negative noise effects and the credibility of the statements in half the subjects. Level of anxiety, subjective noise aversion and time estimation of the noise were taken. The State Anxiety Inventory and the Profile of Mood States Questionnaire were used as pre- and post-tests. Noise increased anxiety levels, these levels being higher during the Statements condition than during the Noise alone condition. Instructions further increased the effects of these negative statements. Subjects did not adapt to noise. Scores in the questionnaires were significantly higher in the post-test than in the pre-test. Implications of these results are discussed.

    Respiratory insufficiency in COPD may present as hypoxic and/or hypercapnic respiratory failure treated with long-term oxygen therapy (LTOT) and/or noninvasive ventilation (NIV) with LTOT. The Severe Respiratory Insufficiency Questionnaire (SRI) is a tool for the assessment of health-related quality of life (HRQOL) in subjects receiving NIV. However, it remains unclear whether the SRI is also capable of assessing and discriminating HRQOL in subjects receiving LTOT. Stable subjects with COPD receiving LTOT or NIV + LTOT (NIV) were prospectively recruited and completed the SRI, lung function tests, and blood gases. Confirmatory factor analysis for construct validity and internal consistency reliability were calculated. One hundred fifty-five subjects were included (113 LTOT, 42 NIV). The Cronbach α coefficient of the 7 subscales ranged between 0.69 and 0.89 (LTOT) and between 0.79 and 0.93 (NIV), respectively. In both groups, confirmatory factor analysis revealed a one-factor model for the SRI summary scale; in 5 subscales, one- or 2-factor models could be established. Group differences in the SRI subsets were all P <.05 (except for physical functioning) with higher scores in subjects receiving NIV. The SRI showed high reliability and validity in subjects with COPD receiving LTOT. Subjects receiving LTOT had lower SRI scores, indicating a poorer HRQOL compared with subjects with established NIV and LTOT. Copyright © 2016 by Daedalus Enterprises.

    2011-04-01

    This research examined the predictive validity of the SAT (formerly, the Scholastic Aptitude Test) for high and low ability groups. SAT scores and college GPAs were obtained from the 1997 National Longitudinal Survey of Youth. Subjects were classified as high or low ability by g factor scores from the Armed Services Vocational Aptitude Battery. SAT correlations with GPA were higher for high than low ability subjects. SAT g loadings (i.e., SAT correlations with g) were equivalent for both groups. This is the first study to show that the predictive validity of the SAT varies for ability groups that differ in g. The results contradict a presumption, based on Spearman's Law of Diminishing Returns, that a test's predictive validity should be lower for high ability subjects. Further research is needed to identify factors that contribute to the predictive validity of the SAT for groups that differ in g.

  14. Higher spins and holography

    2013-05-01

    The principles of quantum mechanics and relativity impose rigid constraints on theories of massless particles with nonzero spin. Indeed, Yang-Mills theory and General Relativity are the unique solution in the case of spin-1 and spin-2. In asymptotically flat spacetime, there are fundamental obstacles to formulating fully consistent interacting theories of particles of spin greater than 2. However, indications are that such theories are just barely possible in asymptotically anti-de Sitter or de Sitter spacetimes, where the non-existence of an S-matrix provides an escape from the theorems restricting theories in Minkowski spacetime. These higher spin gravity theories are therefore of great intrinsic interest, since they, along with supergravity, provide the only known field theories generalizing the local invariance principles of Yang-Mills theory and General Relativity. While work on higher spin gravity goes back several decades, the subject has gained broader appeal in recent years due to its appearance in the AdS/CFT correspondence. In three and four spacetime dimensions, there exist duality proposals linking higher spin gravity theories to specific conformal field theories living in two and three dimensions respectively. The enlarged symmetry algebra of the conformal field theories renders them exactly soluble, which makes them excellent laboratories for understanding in detail the holographic mechanism behind AdS/CFT duality. Steady progress is also being made on better understanding the space of possible higher spin gravity theories and their physical content. This work includes classifying the possible field multiplets and their interactions, constructing exact solutions of the nonlinear field equations, and relating higher spin theories to string theory. A full understanding of these theories will involve coming to grips with the novel symmetry principles that enlarge those of General Relativity and Yang-Mills theory, and one can hope that this will provide

    Full Text Available Background: Dyspepsia is a constellation of symptoms referable to the gastroduodenal region of the upper gastrointestinal tract. Emotional disturbances are often associated with dyspepsia and have been proposed as one of the possible causes of dyspepsia. This study was aimed to evaluate the difference between the severity of dyspepsia using porto alegre dyspeptic symptoms questionnaire (PADYQ and emotional disturbances using depression, anxiety, stress scales (DASS. Method: This study was a cross-sectional analytical study. All the subjects were evaluated using PADYQ and DASS. PADYQ is classified into four categories (no, mild, moderate and severe dyspepsia symptoms. Data was analyzed using Independent t-test and Mann-Whitney test. A p < 0.05 was considered as statistically significant. Results: There were 90 subjects that enrolled in this study, consisted of 47 (52.2% males and 43 (47.8% females. Thirty three (36.7% subjects had PADYQ score was < 6, while it was ≥ 6 in the other 57 (63.3% subjects. DASS scores were significantly different in subjects without dyspepsia symptoms compared to subjects with dyspepsia symptoms. There is a difference in DASS scores between subjects with different categories of dyspepsia symptoms (p < 0.05. Conclusion: There was a difference in the severity of emotional disturbances among subjects with dyspepsia symptoms and without dyspepsia symptoms. The severity of emotional disturbances parallel with the severity of dyspepsia. Evaluation of emotional disturbances in case of dyspepsia will be helpful in the management of dyspepsia.

    Intraoperative crisis is an inevitable event to anesthesiologists. The crisis requires effective and coordinated management once it happened but it is difficult to manage the crises properly under extreme stressful situation. Recently, it is reported that the use of surgical crisis checklists is associated with significant improvement in the management of operating-room crises in a high-fidelity simulation study. Careful preoperative evaluation, proper intraoperative management and using intraoperative crisis checklists will be needed for safer perioperative care in the future. Postoperative complication is a serious public health problem. It reduces the quality of life of patients and raises medical cost. Careful management of surgical patients is required according to their postoperative condition for preventing postoperative complications. A 10-point surgical Apgar score, calculated from intraoperative estimated blood loss, lowest mean arterial pressure, and lowest heart rate, is a simple and available scoring system for predicting postoperative complications. It undoubtedly predicts higher than average risk of postoperative complications and death within 30 days of surgery. Surgical Apgar score is a bridge between proper intraoperative and postoperative care. Anesthesiologists should make effort to reduce the postoperative complication and this score is a tool for it.

    The Oswestry Disability Index (ODI) is one of the most common scoring systems used for patients with low back pain (LBP). Although the normative score of the ODI was reported to be 10.19 in a review article, no study has calculated the normative score after adjusting the value based on the age distribution. In addition, none of the previous studies has estimated the cut-off value which separates LBP with disability from LBP without disability. The purpose of this study was to estimate the normative score by adjusting the data for age distribution in Japan, and to determine the cut-off value which separates LBP with disability from LBP without disability. We conducted an internet survey on LBP using the Japanese version of the ODQ. A total of 1,200 respondents, composed of 100 males and 100 females in each age group (from the 20s to 70s), participated in this study. We also asked them to provide information about their backgrounds. We estimated the normative score after correcting for the age distribution of Japan. We also estimated the ODI of those with or without disability, the factors associated with the ODI, and the cut-off value which separates LBP with disability from LBP without disability. The participants' backgrounds were similar to the national survey. The normative score of the ODI was estimated at 8.73. The ODI of the LBP with disability group was 22.07. Those with sciatica and obese subjects showed higher ODI than those without. The optimal cut-off value was estimated to be 12. We defined the normative score and the cut-off value of the ODI.

    This software (Asset Scoring Tool) is designed to help building owners and managers to gain insight into the as-built efficiency of their buildings. It is a web tool where users can enter their building information and obtain an asset score report. The asset score report consists of modeled building energy use (by end use and by fuel type), building systems (envelope, lighting, heating, cooling, service hot water) evaluations, and recommended energy efficiency measures. The intended users are building owners and operators who have limited knowledge of building energy efficiency. The scoring tool collects minimum building data (~20 data entries) from users and build a full-scale energy model using the inference functionalities from Facility Energy Decision System (FEDS). The scoring tool runs real-time building energy simulation using EnergyPlus and performs life-cycle cost analysis using FEDS. An API is also under development to allow the third-party applications to exchange data with the web service of the scoring tool.

    Chronic subjective dizziness (CSD) is a neurotologic disorder of persistent non-vertiginous dizziness, unsteadiness, and hypersensitivity to one's own motion or exposure to complex visual stimuli. CSD usually follows acute attacks of vertigo or dizziness and is thought to arise from patients' failure to re-establish normal locomotor control strategies after resolution of acute vestibular symptoms. Pre-existing anxiety or anxiety diathesis may be risk factors for CSD. This study tested the hypothesis that patients with CSD are more likely than individuals with other chronic neurotologic illnesses to possess anxious, introverted personality traits. Data were abstracted retrospectively from medical records of 40 patients who underwent multidisciplinary neurotology evaluations for chronic dizziness. Twenty-four subjects had CSD. Sixteen had chronic medical conditions other than CSD plus co-existing anxiety disorders. Group differences in demographics, Dizziness Handicap Inventory (DHI) scores, Hospital Anxiety and Depression Scale (HADS) scores, DSM-IV diagnoses, personality traits measured with the NEO Personality Inventory - Revised (NEO-PI-R), and temperaments composed of NEO-PI-R facets were examined. There were no differences between groups in demographics, mean DHI or HADS-anxiety scores, or DSM-IV diagnoses. The CSD group had higher mean HADS-depression and NEO-PI-R trait anxiety, but lower NEO-PI-R extraversion, warmth, positive emotions, openness to feelings, and trust (all p<0.05). CSD subjects were significantly more likely than comparison subjects to have a composite temperament of high trait anxiety plus low warmth or excitement seeking. An anxious, introverted temperament is strongly associated with CSD and may be a risk factor for developing this syndrome. Copyright © 2013 Elsevier Inc. All rights reserved.

    To evaluate the relationship between objectively measured memory functions and subjective complaints of memory disturbance and whether subjective complaints are affected by some personality traits or affective states. Cross-sectional two-group comparison. The city of Kuopio in Eastern Finland, considered representative of the urban elderly population of Finland. Originally 403 subjects aged 67-78 years from the random sample and then two matched study groups initially including eighteen subjects but only ten in the final analysis. Screening and follow-up examinations of subjects with and without subjective memory complaints: (1) Memory functions: Benton's visual retention test and the paired-associated learning subtest of Wechsler Memory Scale. (2) Memory complaints: Memory Complaint Questionnaire. (3) Personality traits and affective state: Two subscales from Minnesota Multiphasic Personality Inventory and Geriatric Depression Scale. Complaints of memory loss did not correlate with the actual memory performance in the tests. However, those subjects who most emphatically complained of memory disturbance had greater tendencies toward somatic complaining, higher feelings of anxiety about their physical health, and more negative feelings of their own competence and capabilities than those who did not complain of memory deterioration associated with aging. The study suggests that subjective feelings of memory impairment are more closely associated with personality traits than with actual memory performance in normal elderly people.

    We investigated temperamental dimensions of the Temperament Evaluation of Memphis, Pisa and San Diego Autoquestionnaire (TEMPS-A) as well as bipolarity features in male and female subjects engaging in extreme or/and high risk sports. The web-based case-control study was performed in 480 subjects engaging in extreme or/and high risk sports (255 male, 225 female) aged 26 ± 6 years and in 235 age- and sex-matched healthy controls subjects (107 male, 128 female), aged 28 + 9 years. The TEMPS-A questionnaire, 110 questions version, has been used, evaluating five temperament domains: depressive, cyclothymic, hyperthymic, irritable and anxious. The Mood Disorder Questionnaire (MDQ) was employed for the assessment of bipolarity. Both male and female athletes had significantly higher scores of hyperthymic temperaments compared with control male and female subjects who had declared themselves as not involved into the activities of extreme or/and high risk sports. In addition, compared with controls, male sportsmen had lower scores of depressive and anxious temperaments, and female athletes had higher scores of cyclothymic and irritable temperaments. Both male and female athletes obtained significantly higher scores of bipolarity as measured by the MDQ, than control men and women. Web-based study involving a risk of selection and recall bias, problematic homogeneity of the experimental group. Subjects engaged into extreme or/and high risk sports have significantly higher scores of hyperthymic temperament, measured by the TEMPS-A and present sex-specific features of other temperaments. Such subjects obtain also greater bipolarity scores as measured by the MDQ. Copyright © 2014 Elsevier B.V. All rights reserved.

  4. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Directory of Open Access Journals (Sweden)

    2011-02-01

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other.

    The aim of this study was to investigate the association between subjective memory complaints (SMC) and sex. We researched the prevalence of SMC in a sample of 394 participants who were at least 60 years of age (138 male and 256 female). We also administered the Mini-Mental State Examination (MMSE) and the Center for Epidemiologic Studies for Depression (CES-D) scale. A multiple logistic regression analysis, which included SMC in association with the MMSE or CES-D scores and other confounding factors, was performed to determine the influence of sex on SMC. A P-value < 0.05 was considered statistically significant. The durations of education of male participants were significantly higher than those of female participants. MMSE scores for female participants were significantly higher than those for male participants. There was no significant difference in CES-D scores between male and female participants. Twenty-four male participants and 72 female participants showed evidence of SMC. The incidence of SMC was more frequent in female participants than in male participants. In all participants, sex difference and CES-D score were significantly associated with SMC. In male participants, MMSE score was independently and significantly associated with SMC. Both in female participants and all participants, CES-D score was independently and significantly associated with SMC. SMC varied by sex and were associated with the degree of cognitive impairment in male participants, while they were associated with depressive symptoms in female participants.

  6. Stability of cooperation under image scoring in group interactions

    Image scoring sustains cooperation in the repeated two-player prisoner’s dilemma through indirect reciprocity, even though defection is the uniquely dominant selfish behaviour in the one-shot game. Many real-world dilemma situations, however, firstly, take place in groups and, secondly, lack the necessary transparency to inform subjects reliably of others’ individual past actions. Instead, there is revelation of information regarding groups, which allows for ‘group scoring’ but not for image scoring. Here, we study how sensitive the positive results related to image scoring are to information based on group scoring. We combine analytic results and computer simulations to specify the conditions for the emergence of cooperation. We show that under pure group scoring, that is, under the complete absence of image-scoring information, cooperation is unsustainable. Away from this extreme case, however, the necessary degree of image scoring relative to group scoring depends on the population size and is generally very small. We thus conclude that the positive results based on image scoring apply to a much broader range of informational settings that are relevant in the real world than previously assumed.

Methods: This prospective observational cohort study included 88 patients who have had acute ischemic stroke and a control group of 40 patients who were evaluated in the Emergency Department for disorders other than acute ischemic stroke. All subjects had RDW determined, and stroke patients had scoring with the GCS, CNS, and NIHSS scores. The GCS, CNS, and NIHSS scores of the patients were rated as mild, moderate, or severe and compared with RDW. Results: Stroke patients had significantly higher median RDW than control subjects. The median RDW values were significantly elevated in patients who had more severe rather than milder strokes rated with all three scoring systems (GCS, CNS, and NIHSS. The median RDW values were significantly elevated for patients who had moderate rather than mild strokes rated by GCS and CNS and for patients who had severe rather than mild strokes rated by NIHSS. The area under the receiver operating characteristic curve was 0.760 (95% confidence interval, 0.676–0.844. Separation of stroke patients and control groups was optimal with RDW 14% (sensitivity, 71.6%; specificity, 67.5%; accuracy, 70.3%. Conclusion: In stroke patients who have symptoms <24 hours, the RDW may be useful in predicting the severity and functional outcomes of the stroke

    To evaluate the effect of early-warning scoring system design on the speed and accuracy of scoring. Despite the widespread implementation of early-warning scoring systems in hospitals, the speed and accuracy with which chart-users determine patients' early-warning scores has received minimal research attention. Within-subjects, with scoring-system design as the independent variable. Forty-seven novice chart-users were presented with realistic vital sign observations recorded on charts with three different scoring-system designs. The rows for recording individual vital sign scores were either: (1) grouped together beneath all of the vital sign rows; (2) separated, with each row presented immediately below the corresponding vital sign row; or (3) excluded altogether. Participants' response times and error rates for determining the overall scores were measured for 54 time-points per design. Data were collected in December 2012-January 2013. Contrary to predictions, participants responded fastest and made the fewest errors when using the chart design without individual vital sign scoring-rows. For the other two designs, participants were faster when the rows for scoring individual vital signs were separated (vs. grouped), but accuracy did not differ. For both of these designs, significantly more time-points were affected by scoring errors compared with adding errors. Finally, data for patients with more serious derangements yielded greater response times and error rates on all three charts. Early-warning scoring systems may be more effective without individual vital sign scoring-rows. Even when charts are designed by multi-disciplinary teams of human factors specialists and clinicians, empirical evaluations are essential. © 2015 John Wiley & Sons Ltd.

    modelling strategy is applied to different training sets. For each modelling strategy we estimate a confidence score based on the same repeated bootstraps. A new decomposition of the expected Brier score is obtained, as well as the estimates of population average confidence scores. The latter can be used......In medical statistics, many alternative strategies are available for building a prediction model based on training data. Prediction models are routinely compared by means of their prediction performance in independent validation data. If only one data set is available for training and validation......, then rival strategies can still be compared based on repeated bootstraps of the same data. Often, however, the overall performance of rival strategies is similar and it is thus difficult to decide for one model. Here, we investigate the variability of the prediction models that results when the same...

    2008-07-01

    The maximum LOD score statistic is extremely powerful for gene mapping when calculated using the correct genetic parameter value. When the mode of genetic transmission is unknown, the maximum of the LOD scores obtained using several genetic parameter values is reported. This latter statistic requires higher critical value than the maximum LOD score statistic calculated from a single genetic parameter value. In this paper, we compare the power of maximum LOD scores based on three fixed sets of genetic parameter values with the power of the LOD score obtained after maximizing over the entire range of genetic parameter values. We simulate family data under nine generating models. For generating models with non-zero phenocopy rates, LOD scores maximized over the entire range of genetic parameters yielded greater power than maximum LOD scores for fixed sets of parameter values with zero phenocopy rates. No maximum LOD score was consistently more powerful than the others for generating models with a zero phenocopy rate. The power loss of the LOD score maximized over the entire range of genetic parameters, relative to the maximum LOD score calculated using the correct genetic parameter value, appeared to be robust to the generating models.

    2016-07-01

    Meditation Breath Attention Scores (MBAS) represent a self-report, state measure of focused attention (FA) during the practice of meditation. The MBAS assessment procedure involves sounding a bell at periodic intervals during meditation practice, at which times participants indicate if they were attending toward breathing (scored 1) or if instead they had become distracted (e.g., by mind wandering; scored 0); scores are then tallied to yield participants' MBAS for that meditation. The current study developed and evaluated a fully automated and Internet-based version of MBAS in 1,101 volunteers. Results suggested that: (a) MBAS are internally consistent across bell rings; (b) MBAS total scores exhibit a non-normal distribution identifying subgroups of participants with particularly poor or robust FA during meditation; (c) MBAS decrease linearly with the duration of meditation practices, indicating that participants tend to experience less FA later as opposed to earlier in the meditation; (d) in the case of eyes-open meditation, MBAS are higher when the amount of time between bells is shorter; (e) MBAS correlate with various self-reported subjective experiences occurring during meditation; and (f) MBAS are weakly associated with higher trait mindful "acting with awareness," lesser ADHD-related symptoms of inattentiveness, and estimated minutes of meditation practiced in the past month. In sum, results provide further support for the construct validity of MBAS and serve to further characterize the dynamics of individual differences in FA during meditation.

    This study aimed to examine the usefulness of each subscale score of the Clinical Dementia Rating (CDR) for predicting Alzheimer's disease (AD) dementia progression in amnestic mild cognitive impairment (MCI) elderly subjects. Fifty-nine elderly MCI individuals were recruited from a university dementia and memory disorder clinic. Standardized clinical and neuropsychological tests were performed both at baseline and at the time of 2 years follow-up. Logistic regression analyses were conducted to examine the ability of various clinical measures or their combinations to predict progression to AD dementia in MCI individuals. MCIp individuals showed significantly higher CDR Orientation subscale and CDR sum-of-boxes (SOB) score than MCInp ones, while there were no significant differences in other CDR subscale scores between the two. MCIp individuals also showed marginally higher MMSE scores than MCInp ones. A series of logistic regression analyses demonstrated that the model including CDR Orientation subscale had better AD dementia prediction accuracy than either the model with either MMSE or CDR-SOB. Our findings suggest that CDR Orientation subscale score, a simple and easily available clinical measure, could provide very useful information to predict AD dementia progression in amnestic MCI individuals in real clinical settings.

    Malnutrition is closely related to inflammation and atherosclerosis in uraemic patients. There is still debate on how to quantify nutritional status in order to achieve the best prediction of mortality and hospitalization. Different methods to detect malnutrition were prospectively investigated for their prognostic impact on mortality and hospitalization of haemodialysis (HD) patients. We compared clinical nutrition scores (body mass index, BMI; subjective global assessment, SGA; malnutrition inflammation score, MIS; and nutritional risk screening, NRS) to lab parameters of protein and lipid metabolism, or bioelectrical impedance analysis (BIA) in 90 HD patients. Over a 3-year follow-up, all-cause mortality and hospitalization were evaluated using a Cox regression model. The scores SGA, NRS, MIS, serum albumin, prealbumin, transferrin and BIA were predictive of both mortality and hospitalization. Elevated CRP predicted only a significantly higher mortality. After adjustment for age, gender, dialysis vintage and diabetes status, the best prognostic parameters for mortality were the clinical nutrition scores, MIS-Index > or = 10 [HR 6.25 (2.82-13.87), P clinical nutrition scores are superior compared to lab markers and BIA. To confirm malnutrition, we propose using clinical nutrition score generally or at least in the case of two malnutrition-positive parameters (lab, BIA, BMI).

    No scoring system for assessing acute heart failure (AHF) has been reported. Data for 824 AHF patients were analyzed. The subjects were divided into an alive (n=750) and a dead group (n=74). We constructed a predictive scoring system based on eight significant APACHE II factors in the alive group [mean arterial pressure (MAP), pulse, sodium, potassium, hematocrit, creatinine, age, and Glasgow Coma Scale (GCS); giving each one point], defined as the APACHE-HF score. The patients were assigned to five groups by the APACHE-HF score [Group 1: point 0 (n=70), Group 2: points 1 and 2 (n=343), Group 3: points 3 and 4 (n=294), Group 4: points 5 and 6 (n=106), and Group 5: points 7 and 8 (n=11)]. A higher optimal balance was observed in the APACHE-HF between sensitivity and specificity [87.8%, 63.9%; area under the curve (AUC)=0.779] at 2.5 points than in the APACHE II (47.3%, 67.3%; AUC=0.558) at 17.5 points. The multivariate Cox regression model identified belonging to Group 5 [hazard ratio (HR): 7.764, 95% confidence interval (CI) 1.586-38.009], Group 4 (HR: 6.903, 95%CI 1.940-24.568) or Group 3 (HR: 5.335, 95%CI 1.582-17.994) to be an independent predictor of 3-year mortality. The Kaplan-Meier curves revealed a poorer prognosis, including all-cause death and HF events (death, readmission-HF), in Group 5 and Group 4 than in the other groups, in Group 3 than in Group 2 or Group 1, and in Group 2 than in Group 1. The new scoring system including MAP, pulse, sodium, potassium, hematocrit, creatinine, age, and GCS (APACHE-HF) can be used to predict adverse outcomes of AHF.

    Full Text Available A central question of Astroparticle Physics, the origin of cosmic rays, still remains unsolved. HiSCORE (Hundred*i Square-km Cosmic ORigin Explorer is a concept for a large-area wide-angle non-imaging air shower detector, addressing this question by searching for cosmic ray pevatrons in the energy range from 10TeV to few PeV and cosmic rays in the energy range above 100TeV. In the framework of the Tunka-HiSCORE project, first prototypes have been deployed on the site of the Tunka-133 experiment, where we plan to install an engineering array covering an area of the order of 1km2. On the same site, also imaging and particle detectors are planned, potentially allowing a future hybrid detector system. Here we present the HiSCORE detector principle, its potential for cosmic ray origin search and the status of ongoing activities in the framework of the Tunka-HiSCORE experiment.

    Full Text Available Background Bipolar disorder (BD patients have been reported to be associated higher creativity abilities, and recent data tend to support the hypothesis that dopaminergic system that could be associated with creativity. Catechol-O-methyltransferase (COMT is one of the major enzymes involved in the metabolic degradation of dopamine. The COMT gene polymorphism (rs4680 or Val158Met Met allele is reported to cause decreased activity of this enzyme in prefrontal cortex and improve performance in several cognitive domains. Objective The objective of this study was to evaluate the influence of Val158Met on creativity in BD type I and healthy controls. Methods Ninety-seven healthy volunteers and 120 BD type I were genotyped for COMT rs4680 and tested for creativity (Barrow Welsh Art Scale – BWAS and intelligence Wechsler Abbreviated Scale of Intelligence (WASI. Results COMT Met allele positively influenced creativity scores in healthy controls but not in BD subjects during mood episodes and euthymia. The presence of allele Met did not influence IQ scores. No influence of IQ total score on creativity was observed. Limitations control group presented higher IQ scores and euthymic group was under medication use. Discussion Our research suggests positive effect of COMT rs4680 (allele Met on creativity scores in healthy controls. One possible interpretation is that creativity is more likely to be associated with lesser degrees of bipolarity. The fact that the same results were not observed in BD may be associated to dysfunctions in the dopaminergic system that characterizes this disorder. Further studies with larger samples and other types of BD should explore the role of the dopaminergic system in creativity.

    The aims of this study were to examine nasalance score variation for normal adult Japanese speakers of Mid-West dialect and the gender difference in average mean nasalance score. Nasalance scores were obtained using a nasometer model 6200. The sample stimulus "Kitsutsuki passage," constructed of four sentences containing no Japanese nasal sounds, was used three times by each subject. One hundred normal adult speakers (50 women and 50 men) of Japanese served as subjects. The subjects ranged in age from 19 to 35 years of age (24.0 +/- 3.2). A mean nasalance score as well as an overall average nasalance value across speakers was calculated for each subject. The average mean nasalance scores between men and women were compared. The average mean nasalance score for the normal Japanese speakers was 9.1% (+/- 3.9). There was no statistically significant sex difference (p nasometer.

    Full Text Available Objectives: This study investigated the relationship between urease and arginine deiminase system (ADS activities and dental caries through a cross-sectional study. Material and Methods: Urease and ADS activities were measured in saliva and plaque samples from 10 caries-free subjects and 13 caries-active. Urease activity was obtained from the ammonia produced by incubation of plaque and saliva samples in urea. ADS activity was obtained from the ammonia generated by the arginine-HCl and Tris-maleate buffer. Specific activity was defined as micromoles of ammonia per minute per milligram of protein. Shapiro-Wilk statistical test was used to analyze the distribution of the data, and Mann-Whitney test was used to determine the significance of the data. Results: The specific urease activity in saliva and plaque was significantly higher in individuals with low DMFT scores. ADS activity in saliva (6.050 vs 1.350, p=0.0154 and plaque (8.830 vs 1.210, p=0.025 was also higher in individuals with low DMFT scores. Conclusions: Caries-free subjects had a higher ammonia generation activity by urease and arginine deiminase system for both saliva and plaque samples than low caries-active subjects. High levels of alkali production in oral environment were related to caries-free subjects.

  6. Boundary curves of individual items in the distribution of total depressive symptom scores approximate an exponential pattern in a general population

    Full Text Available Background Previously, we proposed a model for ordinal scale scoring in which individual thresholds for each item constitute a distribution by each item. This lead us to hypothesize that the boundary curves of each depressive symptom score in the distribution of total depressive symptom scores follow a common mathematical model, which is expressed as the product of the frequency of the total depressive symptom scores and the probability of the cumulative distribution function of each item threshold. To verify this hypothesis, we investigated the boundary curves of the distribution of total depressive symptom scores in a general population. Methods Data collected from 21,040 subjects who had completed the Center for Epidemiologic Studies Depression Scale (CES-D questionnaire as part of a national Japanese survey were analyzed. The CES-D consists of 20 items (16 negative items and four positive items. The boundary curves of adjacent item scores in the distribution of total depressive symptom scores for the 16 negative items were analyzed using log-normal scales and curve fitting. Results The boundary curves of adjacent item scores for a given symptom approximated a common linear pattern on a log normal scale. Curve fitting showed that an exponential fit had a markedly higher coefficient of determination than either linear or quadratic fits. With negative affect items, the gap between the total score curve and boundary curve continuously increased with increasing total depressive symptom scores on a log-normal scale, whereas the boundary curves of positive affect items, which are not considered manifest variables of the latent trait, did not exhibit such increases in this gap. Discussion The results of the present study support the hypothesis that the boundary curves of each depressive symptom score in the distribution of total depressive symptom scores commonly follow the predicted mathematical model, which was verified to approximate an

    Full Text Available Context: There is paucity of data on the comparison of psychological distress among chronic noncommunicable disease (NCD and healthy subjects in developing countries such as India. Objective: To assess and compare psychological distress and its associated factors among chronic disease and healthy subjects. Materials and Methods: A cross-sectional study was conducted in a rural field practice area attached to a tertiary care medical institution in Puducherry, India. Data were collected from the chronic disease subjects which included those with diabetes and or hypertension registered in the rural health center. Healthy subjects residing nearest to the corresponding case from the respective village were taken as controls. Psychological distress was assessed by General Health Questionnaire 12 (GHQ 12. Results: There were 260 subjects with 130 in each group. Subjects with chronic disease had significantly higher proportion of psychological distress (50.8% compared to healthy subjects (35.4%. The mean ± standard deviation GHQ 12 score of those with chronic disease is also significantly higher than that of healthy subjects (13.35 ± 4.89 vs. 11.15 ± 4.43, P< 0.001. Binary logistic regression analysis showed that subjects with diabetes and/or hypertension had higher psychological distress (adjusted odds ratio = 1.9, 95% confidence interval: 1.1–3.5 compared to healthy subjects. Conclusion: Subjects with diabetes and/or hypertension have higher proportion of psychological distress compared to healthy subjects. Screening subjects with chronic NCD for psychological distress may help to take appropriate measures.

    The endocannabinoid (eCB) system can promote food intake by increasing odor detection in mice. The eCB system is over-active in human obesity. Our aim is to measure circulating eCB concentrations and olfactory capacity in a human sample that includes people with obesity and explore the possible interaction between olfaction, obesity and the eCB system. The study sample was made up of 161 females with five groups of body mass index sub-categories ranging from under-weight to morbidly obese. We assessed olfactory capacity with the "Sniffin´Sticks" test, which measures olfactory threshold-discrimination-identification (TDI) capacity. We measured plasma concentrations of the eCBs 2-arachidonoylglycerol (2-AG) and N-arachidonoylethanolamine or anandamide (AEA), and several eCB-related compounds, 2-acylglycerols and N-acylethanolamines. 2-AG and other 2-acylglycerols fasting plasma circulating plasma concentrations were higher in obese and morbidly obese subjects. AEA and other N-acylethanolamine circulating concentrations were lower in under-weight subjects. Olfactory TDI scores were lower in obese and morbidly obese subjects. Lower TDI scores were independently associated with higher 2-AG fasting plasma circulating concentrations, higher %body fat, and higher body mass index, after controlling for age, smoking, menstruation, and use of contraceptives. Our results show that obese subjects have a lower olfactory capacity than non-obese ones and that elevated fasting plasma circulating 2-AG concentrations in obesity are linked to a lower olfactory capacity. In agreement with previous studies we show that eCBs AEA and 2-AG, and their respective congeners have a distinct profile in relation to body mass index. The present report is the first study in humans in which olfactory capacity and circulating eCB concentrations have been measured in the same subjects.

    2012-12-15

    To design and validate a scoring system for tomosynthesis (digital tomography) in pulmonary cystic fibrosis. A scoring system dedicated to tomosynthesis in pulmonary cystic fibrosis was designed. Three radiologists independently scored 88 pairs of radiographs and tomosynthesis examinations of the chest in 60 patients with cystic fibrosis and 7 oncology patients. Radiographs were scored according to the Brasfield scoring system and tomosynthesis examinations were scored using the new scoring system. Observer agreements for the tomosynthesis score were almost perfect for the total score with square-weighted kappa >0.90, and generally substantial to almost perfect for subscores. Correlation between the tomosynthesis score and the Brasfield score was good for the three observers (Kendall's rank correlation tau 0.68, 0.77 and 0.78). Tomosynthesis was generally scored higher as a percentage of the maximum score. Observer agreements for the total score for Brasfield score were almost perfect (square-weighted kappa 0.80, 0.81 and 0.85). The tomosynthesis scoring system seems robust and correlates well with the Brasfield score. Compared with radiography, tomosynthesis is more sensitive to cystic fibrosis changes, especially bronchiectasis and mucus plugging, and the new tomosynthesis scoring system offers the possibility of more detailed and accurate scoring of disease severity.

    Walk Score® and Transit Score® are open-source measures of the neighborhood built environment to support walking ("walkability") and access to transportation. To investigate associations of Street Smart Walk Score and Transit Score with self-reported transport and leisure walking using data from a large multicity and diverse population-based sample of adults. Data from a sample of 4552 residents of Baltimore MD, Chicago IL, Forsyth County NC, Los Angeles CA, New York NY, and St. Paul MN from the Multi-Ethnic Study of Atherosclerosis (2010-2012) were linked to Walk Score and Transit Score (collected in 2012). Logistic and linear regression models estimated ORs of not walking and mean differences in minutes walked, respectively, associated with continuous and categoric Walk Score and Transit Score. All analyses were conducted in 2012. After adjustment for site, key sociodemographic, and health variables, a higher Walk Score was associated with lower odds of not walking for transport and more minutes/week of transport walking. Compared to those in a "walker's paradise," lower categories of Walk Score were associated with a linear increase in odds of not transport walking and a decline in minutes of leisure walking. An increase in Transit Score was associated with lower odds of not transport walking or leisure walking, and additional minutes/week of leisure walking. Walk Score and Transit Score appear to be useful as measures of walkability in analyses of neighborhood effects. Copyright © 2013 American Journal of Preventive Medicine. Published by Elsevier Inc.

    It has been reported that periodontitis is associated with Alzheimer's disease. However, the association between paranasal sinusitis and Alzheimer's disease has not been studied, although olfactory dysfunction frequently precedes the progress of dementia or Alzheimer's disease. We studied 783 patients (283 men, 500 women; mean age 77.0 ± 7.9 years) who visited the Center for Comprehensive Care and Research on Memory Disorders, National Center for Geriatrics and Gerontology, and 2139 control subjects who participated in a population-based study conducted by the National Institute for Longevity Sciences - Longitudinal Study of Aging (NILS-LSA) in Japan. Sinusitis was evaluated using magnetic resonance imaging (MRI) according to the Lund-Mackay scoring system. A sinusitis score of ≥ 4 was classified as positive and a score of ≤ 3 was classified as negative. The prevalence of positive sinusitis was 6.3% in patients with a mini-mental state examination (MMSE) score of sinusitis was7.2% in the control group. The prevalence of sinusitis was not significantly different between normal controls and patients with dementia or Alzheimer's disease after adjustments for age and sex. The rate of positive sinusitis was higher in male than in female subjects in both groups. The prevalence of sinusitis in patients with Alzheimer's disease or dementia was not higher than in the general population.

    Cerebral arteriovenous malformations (CAVMs) may be treated with microsurgery, radiosurgery, endovascular surgery, or a combination of these modalities. Grading scales are available to aid the assessment of curative risk for microsurgery and radiosurgery. No grading system has been developed to assess the curative risk of endovascular surgery. To report our retrospective application of the AVM embocure score to patients treated at our institution between 2005 and 2011 METHODS: We performed a retrospective review of 39 patients with CAVM treated at our institution between 2005 and 2011 with the primary aim of achieving a curative embolization. After reviewing all the different variables associated with the conventional Onyx embolization technique for CAVMs, we identified the following as the most relevant characteristics influencing the chances for complete angiographic embolization and complication risk: the number of arterial pedicles and draining veins, size of AVM nidus, and vascular eloquence. We sought to develop a scoring system to assess the complication risk for a curative embolization of CAVM with liquid embolic Onyx (Covidien, Irvine, California, USA). We developed the AVM embocure score (AVMES). This scoring system ranges from 3 to 10 and is the arithmetic sum of the number of arterial pedicles feeding the AVM (≤3, 4-6, >6), the number of draining veins (≤3, 4-6, >6), the size of the AVM nidus in centimeters (≤3, 4-6, >6), and the vascular eloquence (0-1). We applied AVMES to the same cohort of patients and validated the predictability of complete angiographic embolization and expected clinical risk of complication. In lesions with an AVMES of 3 (n=8), there was a 100% rate of complete AVM obliteration and 0% rate of major complications. In AVMES 4 (n=12) lesions, there was 75% complete obliteration rate, with 8% major morbidity. In AVMES 5 (n=9) lesions, there was 78% complete obliteration and 11% major morbidity. In AVMES >5 (n=10) there was 20

    Illicit drug use/dependence has been recognized as a major problem. Clinical studies demonstrate that poor sleep quality is associated with increased frequency of drug use and relapse. However, few studies have addressed the issue of sleep quality among illicit drug dependent subjects. This cross-sectional study explored sleep quality in drug dependent subjects in China. We studied 2178 illicit drug dependent subjects from drug rehabilitation centres in Changsha and 2236 non-drug-using subjects, all of whom completed the self-report Pittsburgh Sleep Quality Index (PSQI). We found that the prevalence of sleep disturbance was much higher in drug users (68.5%, PSQI >5; specifically, 80.24% in heroin users, 54.16% in methamphetamine users and 81.98% in ketamine users with PSQI >5) than non-users (26.4%, PSQI >5). Drug users had approximately twice the sleep latency than nondrug users (37.7 minutes V.S 18.4 minutes). Although drug users and non-users reported similar sleep duration (about 7.4 hours), drug users showed poorer subjective sleep quality and habitual sleep efficiency. They reported more sleep disturbance and need for sleep medications, more daytime dysfunction and poorer subjective sleep quality compared with nondrug users. The total PSQI score positively correlated with the duration of drug use (rp = 0.164, p sleep problems and cigarette smoking, alcohol drinking, and duration of drug use. Poor sleep quality is common among illicit drug dependent subjects. Long-term substance users had more sleep problems. Future research aiming at quantifying the benefits of treatment interventions should not neglect the influence of sleep problems. Gaining more insight into the impact of sleep quality on the addiction treatment could also help to target future intervention measures more effectively.

    Prostate cancer Gleason score 6 is the most common score detected on prostatic biopsy. We analyzed the clinical parameters that predict the likelihood of Gleason score upgrading after radical prostatectomy. The study population consisted of 241 patients who underwent radical retropubic prostatectomy between Feb 2002 and Dec 2007 for Gleason score 6 adenocarcinoma. The influence of preoperative parameters on the probability of a Gleason score upgrading after surgery was evaluated using multivariate logistic regression and ROC curves. Gleason score upgrade was found in 92 of 241 patients (38.2%). Multivariate logistic regression analysis showed that only percentage of cancer in dominant lobe and prostate weight were significant predictors for Gleason score upgrading (p = 0.043 and p = 0.006, respectively). ROC curves showed that prostate weight and PSA density were only two independent significant parameters for prediction of upgrade (AUC - 0.634, p Gleason score upgrading was observed to be accompanied by significantly higher rates of extra prostatic extension (p Gleason 6 at biopsy are Gleason 7 at surgery. Upgraded tumors significantly associated with adverse pathological features. The probability of Gleason score upgrade can be predicted using prostate weight and PSA density as independent parameters.

    Full Text Available ABSTRACT Background - Several scoring was developed for evaluation of children with fecal retention using plain radiograph. There are controversies about specificity and sensitivity of these scoring system. Objectives - The aim of this study was to evaluate Barr, Blethyn, and Leech score in evaluation of fecal load in plain radiograph. Methods - This case control study was conducted on children aged 2-14 years old with abdominal pain who visited Abuzar children's Hospital of Ahvaz University of Medical Sciences. This study was conducted in fall season. Children with history of previous abdominal surgery, any systemic illness including sickle cell anemia were excluded. Children with constipation were placed in case group. Subjects without constipation were placed in control group. Subjects without exclusion criteria were examined by physician who is blind to aim of the study. Careful history and physical examination was done. Demographic features, history of gastrointestinal problem, duration of abdominal pain, defecation habit, stool consistency (loose, hard, and results of physical examination were recorded. Rome III criteria was used for definition of constipation. Abdominal x-ray was ordered for each patients. Abdominal radiography was reviewed by radiologist. Barr, Leach, and Blethyn scores were calculated for each case. Results - In this study 102 children with functional constipation and 102 children without constipation as a control were included. Mean ±SD for case and control group was 68.39±34.88 and 69.46±32.60 (P=0.82.Leech score (mean ±SD was 11.05±2.177 and 5.67±3.228 for case and control group respectively (P<0.0001.

    Dietary pattern analysis, based on the concept that foods eaten together are as important as a reductive methodology characterized by a single food or nutrient analysis, has emerged as an alternative approach to study the relation between nutrition and disease. The aim of the present study was to compare nutritional intake and the results of dietary pattern analysis in properly matched vegetarian and omnivorous subjects. Vegetarians (n = 69) were recruited via purposeful sampling and matched non-vegetarians (n = 69) with same age, gender, health and lifestyle characteristics were searched for via convenience sampling. Two dietary pattern analysis methods, the Healthy Eating Index-2010 (HEI-2010) and the Mediterranean Diet Score (MDS) were calculated and analysed in function of the nutrient intake. Mean total energy intake was comparable between vegetarians and omnivorous subjects (p > 0.05). Macronutrient analysis revealed significant differences between the mean values for vegetarians and omnivorous subjects (absolute and relative protein and total fat intake were significantly lower in vegetarians, while carbohydrate and fibre intakes were significantly higher in vegetarians than in omnivorous subjects). The HEI and MDS were significantly higher for the vegetarians (HEI = 53.8.1 ± 11.2; MDS = 4.3 ± 1.3) compared to the omnivorous subjects (HEI = 46.4 ± 15.3; MDS = 3.8 ± 1.4). Our results indicate a more nutrient dense pattern, closer to the current dietary recommendations for the vegetarians compared to the omnivorous subjects. Both indexing systems were able to discriminate between the vegetarians and the non-vegetarians with higher scores for the vegetarian subjects.

    This study is intended to clarify the relationships between hearing loss caused both by noise exposure and aging and self-rated scores of hearing disabilities and to elucidate the structure of the quality of life (QOL) determinants and their moderating conditions among retired workers with noise-related hearing loss. The questionnaire consisted of three parts: background questions, the hearing disabilities and handicap scale (HDHS), and questions regarding QOL covering five areas, self-rated health, personal health practice, social support network, life satisfaction, and life events. Two hundred ten retired workers aged 56-65 years old (60·6±1·6) with noise-related hearing loss responded to our questionnaire. All were previously engaged in noise exposed work such as shipbuilding, steel and woodwork. According to the hearing disability score (DIS score), subjects were divided into three groups and comparisons were made of the hearing handicap score (HD score) among those groups. Although groups with a higher DIS score showed a higher HD score, a large individual difference in HD score was observed in each of the three groups with the same DIS score level. The results of multiple regression analysis including two variables (life satisfaction and HD score) as the dependent variables and seven variables as the independent variables showed that the strongest explanatory variable for life satisfaction was social support network, followed by handicaps caused by hearing disabilities, self-rated health and personal health practice. It was demonstrated that hearing disabilities and handicap measured by the Japanese version of the HDHS were directly associated with the deterioration in QOL. Measures of the social support network, life satisfaction, and hearing disabilities and handicaps may assist in the detection of workers who can be targeted for a variety of interventions, such as audiological rehabilitation or the creation of a barrier-free community that is supportive

    The clinical diagnosis of Complex Regional Pain Syndrome (CRPS) is a dichotomous (yes/no) categorization necessary for clinical decision-making. However, such dichotomous diagnostic categories do not convey an individual's subtle and temporal gradations in severity of the condition, and have poor statistical power when used as an outcome measure in research. This study evaluated the validity and potential utility of a continuous type score to index severity of CRPS. Psychometric and medical evaluations were conducted in 114 CRPS patients and 41 non-CRPS neuropathic pain patients. Based on the presence/absence of 17 clinically-assessed signs and symptoms of CRPS, an overall CRPS Severity Score (CSS) was derived. The CSS discriminated well between CRPS and non-CRPS patients (pCRPS diagnoses using both IASP diagnostic criteria (Eta=0.69) and proposed revised criteria (Eta=0.77-0.88). Higher CSS was associated with significantly higher clinical pain intensity, distress, and functional impairments, as well as greater bilateral temperature asymmetry and thermal perception abnormalities (p'sCRPS, and support its validity as an index of CRPS severity. Its utility as an outcome measure in research studies is also suggested, with potential statistical advantages over dichotomous diagnostic criteria. Copyright © 2010. Published by Elsevier B.V.

    An original symptom score sheet named "Anaphylaxis Scoring Aichi (ASCA)" was created to quantitatively determine the severity of allergic symptoms provoked in an oral food challenge. ASCA lists and sorts subjective and objective symptoms into five organs (respiratory, skin-mucosal, gastrointestinal, psycho-neurological and cardiovascular). The organ scores were given (0 to 60 points) in accordance with the severity of each symptom. The total score was defined as the sum of the highest 5 organ scores (maximum 240 points) observed throughout the course of an OFC. This study evaluated the ASCA score in 253 cases of a positive food challenge (age 1-16 years, mean 5.3±3.2 years) conducted from April to August 2011 in our institute. The results were compared to the modified anaphylaxis grading presented in the Japanese Pediatric Guideline for Oral Food Challenge Test in Food Allergy 2009. At the same time, we evaluated the indications of symptomatic treatment using ASCA score. The total score closely correlated with the anaphylaxis grading, but there was a wide range of overlap between grade 2 and grade 3. All cases with a total score≥60 points were equivalent to grade 4 or 5, and that were consisted of three or more organ symptoms. These severe cases contained respiratory or skin/mucosal symptoms, and despite the early induction of initial therapy, the symptoms became worse. ASCA is therefore considered to be a useful tool for use in an oral food challenge test.

    Full Text Available ABSTRACT OBJECTIVE: Translation, cultural adaptation, and validation of the new version of the Knee Society Score - The 2011 KS Score - into Brazilian Portuguese and verification of its measurement properties, reproducibility, and validity. In 2012, the new version of the Knee Society Score was developed and validated. This scale comprises four separate subscales: (a objective knee score (seven items: 100 points; (b patient satisfaction score (five items: 40 points; (c patient expectations score (three items: 15 points; and (d functional activity score (19 items: 100 points. METHOD: A total of 90 patients aged 55-85 years were evaluated in a clinical cross-sectional study. The pre-operative translated version was applied to patients with TKA referral, and the post-operative translated version was applied to patients who underwent TKA. Each patient answered the same questionnaire twice and was evaluated by two experts in orthopedic knee surgery. Evaluations were performed pre-operatively and three, six, or 12 months post-operatively. The reliability of the questionnaire was evaluated using the intraclass correlation coefficient (ICC between the two applications. Internal consistency was evaluated using Cronbach's alpha. RESULTS: The ICC found no difference between the means of the pre-operative, three-month, and six-month post-operative evaluations between sub-scale items. CONCLUSION: The Brazilian Portuguese version of The 2011 KS Score is a valid and reliable instrument for objective and subjective evaluation of the functionality of Brazilian patients who undergo TKA and revision TKA.

    2015-01-01

    The aim of the present study has been to critically review 22 disease scoring systems (DSSs) on oral lichen planus (OLP) that have been reported in the literature during the past decades. Although the presently available DSSs may all have some merit, particularly for research purposes, the diversity of both the objective and subjective parameters used in these systems and the lack of acceptance of one of these systems for uniform use, there is a need for an international, authorized consensus meeting on this subject. Because of the natural course of OLP characterized by remissions and exacerbations and also due to the varying distribution pattern and the varying clinical types, e.g. reticular and erosive, the relevance of a DSS based on morphologic parameters is somewhat questionable. Instead, one may consider to only look for a quality of life scoring system adapted for use in OLP patients. Key words:Oral lichen planus, disease scoring system, classification. PMID:25681372

  8. Interpreting force concept inventory scores: Normalized gain and SAT scores

    Full Text Available Preinstruction SAT scores and normalized gains (G on the force concept inventory (FCI were examined for individual students in interactive engagement (IE courses in introductory mechanics at one high school (N=335 and one university (N=292, and strong, positive correlations were found for both populations (r=0.57 and r=0.46, respectively. These correlations are likely due to the importance of cognitive skills and abstract reasoning in learning physics. The larger correlation coefficient for the high school population may be a result of the much shorter time interval between taking the SAT and studying mechanics, because the SAT may provide a more current measure of abilities when high school students begin the study of mechanics than it does for college students, who begin mechanics years after the test is taken. In prior research a strong correlation between FCI G and scores on Lawson’s Classroom Test of Scientific Reasoning for students from the same two schools was observed. Our results suggest that, when interpreting class average normalized FCI gains and comparing different classes, it is important to take into account the variation of students’ cognitive skills, as measured either by the SAT or by Lawson’s test. While Lawson’s test is not commonly given to students in most introductory mechanics courses, SAT scores provide a readily available alternative means of taking account of students’ reasoning abilities. Knowing the students’ cognitive level before instruction also allows one to alter instruction or to use an intervention designed to improve students’ cognitive level.

    To study patients' expectations of subthalamic deep brain stimulation (STN-DBS) and their subjective perceived outcome, by using qualitative and quantitative methods in Parkinson's disease (PD). PD patients were prospectively examined before and 3 months after surgery. Semistructured interviews regarding preoperative expectations and postsurgical subjective perceived outcome were conducted. These were analysed using content analysis. For statistical analyses, patients were classified according to their subjective perceived outcome, resulting in three different subjective outcome groups (negative, mixed, positive outcome). The groups were used for multiple comparisons between and within each group regarding motor impairment, quality of life (QoL), neuropsychiatric status and cognitive functioning, using standard instruments. A logistic regression analysis was conducted to find predictors of subjective negative outcome. Receiver operating characteristic curves were used to analyse cut-off scores for predictive tests. Of the 30 PD patients participating, 8 had a subjective negative outcome, 8 a mixed and 14 a positive outcome. All groups significantly improved in motor functioning. Patients with subjective negative outcome were characterised by preoperative unrealistic expectations, no postsurgical improvement in QoL, and significantly higher presurgical and postsurgical apathy and depression scores. Higher preoperative apathy and depression scores were significant predictors of negative subjective outcome. Cut-off scores for apathy and depression were identified. The mixed-method approach proved useful in examining a patient's subjective perception of STN-DBS outcome. Our results show that significant motor improvement does not necessarily lead to a positive subjective outcome. Moreover, PD patients should be screened carefully before surgery regarding apathy and depression. (DRKS-ID: DRKS00003221).

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

  16. Scoring of nonmetric cranial traits: a methodological approach

    1999-01-01

    The purpose of the present study was to analyse the replicability of the scoring of discontinuous traits. This was assessed on a sample of 100 skulls from the Frassetto collection (Dipartimento di Biologia Evoluzionistica Sperimentale of Bologna University) analysed through intraobserver comparisons: the discontinuous traits were determined on the same skulls and by the same observer on 3 separate occasions. The scoring was also assessed through interobserver comparisons: 3 different observers performed an independent survey on the same skulls. The results show that there were no significant differences in the discontinuous trait frequencies between the 3 different scorings by the same observer, but there were sometimes significant differences between different observers. Caution should thus be taken in applying the frequencies of these traits to population research. After an indispensable control of material conditions (subject age included), consideration must be given to standardisation procedures between observers, otherwise this may be an additional source of variability in cranial discontinuous trait scoring.

This was assessed on a sample of 100 skulls from the Frassetto collection (Dipartimento di Biologia Evoluzionistica Sperimentale of Bologna University) analysed through intraobserver comparisons: the discontinuous traits were determined on the same skulls and by the same observer on 3 separate occasions. The scoring was also assessed through interobserver comparisons: 3 different observers performed an independent survey on the same skulls. The results show that there were no significant differences in the discontinuous trait frequencies between the 3 different scorings by the same observer, but there were sometimes significant differences between different observers. Caution should thus be taken in applying the frequencies of these traits to population research. After an indispensable control of material conditions (subject age included), consideration must be given to standardisation procedures between observers, otherwise this may be an additional source of variability in cranial discontinuous trait scoring.

    Multidimensional computer adaptive testing (MCAT) can provide higher precision and reliability or reduce test length when compared with unidimensional CAT or with the paper-and-pencil test. This study compared five item selection procedures in the MCAT framework for both domain scores and overall scores through simulation by varying the structure of item pools, the population distribution of the simulees, the number of items selected, and the content area. The existing procedures such as Volume (Segall in Psychometrika, 61:331-354, 1996), Kullback-Leibler information (Veldkamp & van der Linden in Psychometrika 67:575-588, 2002), Minimize the error variance of the linear combination (van der Linden in J. Educ. Behav. Stat. 24:398-412, 1999), and Minimum Angle (Reckase in Multidimensional item response theory, Springer, New York, 2009) are compared to a new procedure, Minimize the error variance of the composite score with the optimized weight, proposed for the first time in this study. The intent is to find an item selection procedure that yields higher precisions for both the domain and composite abilities and a higher percentage of selected items from the item pool. The comparison is performed by examining the absolute bias, correlation, test reliability, time used, and item usage. Three sets of item pools are used with the item parameters estimated from real live CAT data. Results show that Volume and Minimum Angle performed similarly, balancing information for all content areas, while the other three procedures performed similarly, with a high precision for both domain and overall scores when selecting items with the required number of items for each domain. The new item selection procedure has the highest percentage of item usage. Moreover, for the overall score, it produces similar or even better results compared to those from the method that selects items favoring the general dimension using the general model (Segall in Psychometrika 66:79-97, 2001); the

    Full Text Available Abstract Background Over-diagnosis and treatment of prostate cancer has been a major problem in prostate cancer care and management. Currently the most relevant prognostic factor to predict a patient's risk of death due to prostate cancer is the Gleason score of the biopsied tissue samples. However, pathological analysis is subjective, and the Gleason score is only a qualitative estimate of the cancer malignancy. Molecular biomarkers and diagnostic tests that can accurately predict prostate tumor aggressiveness are rather limited. Method We report here for the first time the development of a nanoparticle test that not only can distinguish prostate cancer from normal and benign conditions, but also has the potential to predict the aggressiveness of prostate cancer quantitatively. To conduct the test, a prostate tissue lysate sample is spiked into a blood serum or human IgG solution and the spiked sample is incubated with a citrate-protected gold nanoparticle solution. IgG is known to adsorb to citrate-protected gold nanoparticles to form a "protein corona" on the nanoparticle surface. From this study, we discovered that certain tumor-specific molecules can interact with IgG and change the adsorption behavior of IgG to the gold nanoparticles. This change is reflected in the nanoparticle size of the assay solution and detected by a dynamic light scattering technique. Assay data were analyzed by one-way ANOVA for multiple variant analysis, and using the Student t-test or nonparametric Mann-Whitney U-tests for pairwise analyses. Results An inverse, quantitative correlation of the average nanoparticle size of the assay solution with tumor status and histological diagnostic grading was observed from the nanoparticle test. IgG solutions spiked with prostate tumor tissue exhibit significantly smaller nanoparticle size than the solutions spiked with normal and benign tissues. The higher grade the tumor is, the smaller the nanoparticle size is. The test

    To evaluate outcome of prophylactic clotting factor replacement in children with haemophilia, the Haemophilia Joint Health Score (HJHS) was developed aiming at scoring early joint changes in children aged 4-18. The HJHS has been used for adults on long-term prophylaxis but interpretation of small changes remains difficult. Some changes in these patients may be due to sports-related injuries. Evaluation of HJHS score in healthy adults playing sports could improve the interpretation of this score in haemophilic patients. The aim of this study was to evaluate the HJHS scores in a cohort of young, healthy men participating in sports. Concomitant with a project collecting MRI images of ankles and knees in normal young adults, HJHS scores were assessed in 30 healthy men aged 18-26, participating in sports one to three times per week. One physiotherapist assessed their clinical function using the HJHS 2.1. History of joint injuries was documented. MRI images were scored by a single radiologist, using the International Prophylaxis Study Group additive MRI score. Median age of the study group was 24.3 years (range 19.0-26.4) and median frequency of sports activities was three times per week (range 1-4). Six joints (five knees, one ankle) had a history of sports-related injury. The median overall HJHS score was 0 out of 124 (range 0-3), with 60% of subjects showing no abnormalities on HJHS. All joints were normal on MRI. These results suggest that frequent sports participation and related injuries are not related with abnormalities in HJHS scores. © 2013 John Wiley & Sons Ltd.

    Objectives: To intraindividually evaluate the potential of 4th generation iterative reconstruction (IR) on brain CT with regard to subjective and objective image quality. Methods: 31 consecutive raw data sets of clinical routine native sequential brain CT scans were reconstructed with IR level 0 (= filtered back projection), 1, 3 and 4; 3 different brain filter kernels (smooth/standard/sharp) were applied respectively. Five independent radiologists with different levels of experience performed subjective image rating. Detailed ROI analysis of image contrast and noise was performed. Statistical analysis was carried out by applying a random intercept model. Results: Subjective scores for the smooth and the standard kernels were best at low IR levels, but both, in particular the smooth kernel, scored inferior with an increasing IR level. The sharp kernel scored lowest at IR 0, while the scores substantially increased at high IR levels, reaching significantly best scores at IR 4. Objective measurements revealed an overall increase in contrast-to-noise ratio at higher IR levels, which was highest when applying the soft filter kernel. The absolute grey-white contrast decreased with an increasing IR level and was highest when applying the sharp filter kernel. All subjective effects were independent of the raters' experience and the patients' age and sex. Conclusion: Different combinations of IR level and filter kernel substantially influence subjective and objective image quality of brain CT. (orig.)

    Study Design Survey of 100 worldwide spine surgeons. Objective To develop a spine injury score for the AOSpine Thoracolumbar Spine Injury Classification System. Methods Each respondent was asked to numerically grade the severity of each variable of the AOSpine Thoracolumbar Spine Injury Classification System. Using the results, as well as limited input from the AOSpine Trauma Knowledge Forum, the Thoracolumbar AOSpine Injury Score was developed. Results Beginning with 1 point for A1, groups A, B, and C were consecutively awarded an additional point (A1, 1 point; A2, 2 points; A3, 3 points); however, because of a significant increase in the severity between A3 and A4 and because the severity of A4 and B1 was similar, both A4 and B1 were awarded 5 points. An uneven stepwise increase in severity moving from N0 to N4, with a substantial increase in severity between N2 (nerve root injury with radicular symptoms) and N3 (incomplete spinal cord injury) injuries, was identified. Hence, each grade of neurologic injury was progressively given an additional point starting with 0 points for N0, and the substantial difference in severity between N2 and N3 injuries was recognized by elevating N3 to 4 points. Finally, 1 point was awarded to the M1 modifier (indeterminate posterolateral ligamentous complex injury). Conclusion The Thoracolumbar AOSpine Injury Score is an easy-to-use, data-driven metric that will allow for the development of a surgical algorithm to accompany the AOSpine Thoracolumbar Spine Injury Classification System.

    The aim of this study was to obtain normative nasalance scores for adult and children subjects speaking Turkish language and obtain a reference for normality when nasality is evaluated. Mean nasalance scores were obtained from 35 normal-speaking children aged 7 to 13 years, and 125 adults aged 18 to 69 years during the repetition of 3 nasalance passages that were categorized according to the amount of nasal consonants (oral, oronasal, and nasal passages). The Nasometer (model 6400) was used to obtain nasalance scores for the 3 reading passages. Group mean ± SD nasalance scores of children for oral passage, oronasal passage, and nasal passage were 15.14 ± 4.81, 37.76 ± 4.42, and 49.23 ± 6.95, respectively. Nasalance scores for the adult group were 13.46 ± 6.26, 37.84 ± 6.13, and 50.28 ± 7.77, respectively. There were significant differences in mean nasalance scores for oral versus nasal materials both for children and adult groups. The present study provides normative nasalance scores for Turkish-speaking children and adults. The results indicated acceptable differentiation between oral and nasal materials.

    This research examined the predictive validity of the SAT (formerly, the Scholastic Aptitude Test) for high and low ability groups. SAT scores and college GPAs were obtained from the 1997 National Longitudinal Survey of Youth. Subjects were classified as high or low ability by g factor scores from the Armed Services Vocational Aptitude Battery. SAT correlations with GPA were higher for high than low ability subjects. SAT g loadings (i.e., SAT correlations with g) were equivalent for both groups. This is the first study to show that the predictive validity of the SAT varies for ability groups that differ in g. The results contradict a presumption, based on Spearman’s Law of Diminishing Returns, that a test’s predictive validity should be lower for high ability subjects. Further research is needed to identify factors that contribute to the predictive validity of the SAT for groups that differ in g. PMID:21562615

    Full Text Available Objective. To compare Visual Analogue Scale (VAS scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization. Methods. VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved pain control following gynecologic surgery. Results. The mean age of the 219 participants was 54 (range19 to 94. We did not detect any association between VAS and pain medication utilization for patient-controlled anesthesia (PCA or RN administered (intravenous or oral medications. We also did not detect any association between the number of VAS scores recorded and mean pain scores. Conclusion. Postoperative VAS scores do not predict pain medication use in catheterized women inpatients following gynecologic surgery. Increased pain severity, as reflected by higher VAS scores, is not associated with an increase in pain assessment. Our findings suggest that VAS scores are of limited utility for optimal pain control. Alternative or complimentary methods may improve pain management.

    This study was designed to compare nasalance scores obtained with the old Nasometer 6200 and the new Nasometer II 6400, and to evaluate test-retest reliability of nasalance scores on each machine. Nasalance scores were obtained for 60 subjects reading each of two stimuli. Each subject read each stimulus two times on one machine; the headgear was removed and replaced and each stimulus was read a third time. The same procedure was then repeated with the second machine. Within machines, nasalance scores were compared for repeated stimuli with and without headgear change. The first reading of each stimulus with each machine was used to compare nasalance scores across machines. The subjects were 60 adults with normal speech ranging in age from 19 to 59 years. The main outcome measures were the 12 nasalance scores obtained for each of 60 subjects. For both passages, there was a significant difference in nasalance scores between the old Nasometer and the Nasometer II; however, the actual variability that could be attributed to a difference between machines was small. Most of the variability between machines could be explained as within-subject performance variability and variability associated with headgear change. There was no significant difference in repeated scores within machines with or without headgear change. For clinical purposes, care should be exercised when comparing nasalance scores between the old Nasometer and the Nasometer II.

    In dermatology, it is known that there is a significant co-morbidity between dermatological disorders and psychological complications, and it has been estimated that in at least one-third of patients with skin diseases, their effective management involves consideration of associated emotional factors. In Africa, particularly Nigeria, despite the prevalent dermatological disorders with their possible attendant mental health complications, little or no work has been done in the field of psycho-dermatology, hence the rationale for this study. A prospective study was carried out in the dermatology/venerology clinic of Lagos University Teaching Hospital (LUTH). Ethical clearance and consent were obtained to conduct the study. The subjects were selected by simple random sampling from adult patients that have had their dermatological disorders for at least six months before presentation in the clinic. Those with other co-existing chronic medical illness such as hypertension, diabetes, or haemoglobinopathy were excluded from the study. Controls were obtained to match for age and sex from apparently healthy workers in a nearby general hospital. Each subject was evaluated with a questionnaire to obtain necessary socio-demographic data: Psychache scale (PAS), and subscales C, D, and J of Symptom Check List (SCL-90). The data generated was analyzed to obtain means, and t-test was used to compare the means; p = 0.05 was taken as being significant. The analyses were done using SPSS version 10. Eighty subjects with dermatological disorders, and of equal sex distribution, were evaluated, with mean age of 33 +/- 12.1 years. Equal number of controls matched for sex and mean age of 34.6 +/- 7.3 years were also evaluated. Among the subjects, 16.3% had Acne, followed by Urticaria (13.8%), Vitiligo (12.5%), Tinea (11.3%), Hansen's disease (5%), and others (41.1%). From assessment with PAS and SCL subscales, the mean scores by the subjects were much higher than those of the controls and

    The American Orthopaedic Foot & Ankle Society (AOFAS) score is one of the most common and adapted outcome scales in hallux valgus surgery. However, AOFAS is predominantly physician based and not patient based. Although it may be straightforward to derive statistical significance, it may not equate to the true subjective benefit of the patient's experience. There is a paucity of literature defining MCID for AOFAS in hallux valgus surgery although it could have a great impact on the accuracy of analyzing surgical outcomes. Hence, the primary aim of this study was to define the Minimal Clinically Important Difference (MCID) for the AOFAS score in these patients, and the secondary aim was to correlate patients' demographics to the MCID. We conducted a retrospective cross-sectional study. A total of 446 patients were reviewed preoperatively and followed up for 2 years. An anchor question was asked 2 years postoperation: "How would you rate the overall results of your treatment for your foot and ankle condition?" (excellent, very good, good, fair, poor, terrible). The MCID was derived using 4 methods, 3 from an anchor-based approach and 1 from a distribution-based approach. Anchor-based approaches were (1) mean difference in 2-year AOFAS scores of patients who answered "good" versus "fair" based on the anchor question; (2) mean change of AOFAS score preoperatively and at 2-year follow-up in patients who answered good; (3) receiver operating characteristic (ROC) curves method, where the area under the curve (AUC) represented the likelihood that the scoring system would accurately discriminate these 2 groups of patients. The distribution-based approach used to calculate MCID was the effect size method. There were 405 (90.8%) females and 41 (9.2%) males. Mean age was 51.2 (standard deviation [SD] = 13) years, mean preoperative BMI was 24.2 (SD = 4.1). Mean preoperative AOFAS score was 55.6 (SD = 16.8), with significant improvement to 85.7 (SD = 14.4) in 2 years ( P value

    Assessment of adolescents' dietary habits is challenging. Reliable instruments to monitor dietary trends are required to promote healthier behaviours in this group. The purpose of this cross-sectional study was to assess adolescents' adherence to Norwegian dietary recommendations with a diet score and to report results from, and test-retest reliability of, the score. The diet score involved seven food groups and one physical activity indicator, and was applied to answers from a semi-quantitative food frequency questionnaire (FFQ) administered twice. Reproducibility of the score was assessed with Cohen's Kappa (κ statistics) at an interval of three months. The setting was eight lower-secondary schools in Hordaland County, Norway, and subjects were adolescents (n = 472) aged 14-15 years and their caregivers. Results showed that the proportion of adolescents consistently classified by the diet score was 87.6% (κ = 0.465). For food groups, proportions ranged from 74.0% to 91.6% (κ = 0.249 to κ = 0.573). Less than 40% of the participants were found to adhere to recommendations for frequencies of eating fruits, vegetables, added sugar, and fish. Highest compliance to recommendations was seen for choosing water as beverage and limit the intake of red meat. The score was associated with parental socioeconomic status. The diet score was found to be reproducible at an acceptable level. Health promoting work targeting adolescents should emphasize to increase the intake of recommended foods to approach nutritional guidelines.

    The association between sleep disturbances and cognitive decline in the elderly has been putative and controversial. We evaluated the relation between subjective sleep quality and cognitive function in the Korean elderly. Among 459 community-dwelling subjects, 352 subjects without depression or neurologic disorders (mean age 68.2 ± 6.1) were analyzed in this study. All the participants completed the Korean version of the consortium to establish a registry for Alzheimer's disease neuropsychological battery (CERAD-KN) as an objective cognitive measure and subjective memory complaints questionnaire (SMCQ). Based on the Pittsburgh sleep quality index, two types of sleepers were defined: 'good sleepers' and 'poor sleepers'. There were 192 good sleepers (92 men) and 160 poor sleepers (51 men). Poor sleepers reported more depressive symptoms and more use of sleep medication, and showed higher SMCQ scores than good sleepers, but there was no difference in any assessments of CERAD-KN. In the regression analysis, depressive symptoms and subjective sleep quality were associated with subjective memory complaints (β = 0.312, p poor sleep quality was associated with subjective memory complaints, but not with objective cognitive measures. As subjective memory complaints might develop into cognitive disorders, poor sleep quality in the elderly needs to be adequately controlled.

    Standardized patients (SPs) tend to rate medical students' communication skills subjectively and comprehensively, in contrast to such objective skill set defined in the clinical performance examination (CPX). Meanwhile, medical school instructors have a different approach in their evaluation of students' communication skills. We aim to analyze medical students' verbal communication skills using objective methods, and to determine the contributing factors of a patient-physician interaction (PPI) score. Students with high- and low-ranking scores for PPI in CPX were selected. The Roter interaction analysis system was used to compare verbal communication behaviors of the students and SPs. Patient-centeredness scores (PCSs), physician's verbal dominance, and number of utterances were compared between the two groups. PCSs and physician's verbal dominance had no difference between the groups. The number of utterances during the limited time of 5 minutes of CPX was higher for the high-ranking students. They tended to employ more paraphrase/check for understanding, and closed questions for psychosocial state and open questions for medical condition. The SPs interviewed by high-ranking students gave more medical information and requested for more services. In the case of the routine checkup, smooth conversations with more frequent utterances were detected in the high-ranking students. More medical information exchange and requests for services by SPs were higher for the high-ranking students. Medical communication instructors should keep in mind that our results could be indicators of a high PPI score.

    Children with sickle cell anemia (SCA) are faced with complications which may interfere with their educational activities including academic performance. Reports on their academic performance are mainly from developed countries and the results have been inconsistent. This study aimed to determine the academic performance of primary school-aged children with SCA in Nigeria and compare findings with a group of controls. Ninety children with SCA aged 5-11 years were consecutively recruited at the SCA clinic of UNTH Enugu and their age- and sex-matched normal classmates were enrolled as controls. Academic performance of the children with SCA was studied using the overall scores achieved in the three term examinations in the preceding academic year (2009/2010), while their intelligence quotient (IQ) was determined using the Draw-A-Person Test. The findings were compared with that of 90 controls. The mean overall academic score of the children with SCA of 62.71 ± 19.43% was similar to 67.47 ± 16.42% in the controls (P = .077). However, a significantly higher number of children with SCA (32.2% vs. 16.7% of the controls; P = .015) scored below 50%, thus, had poor performance. The mean IQ of the subjects (91.41 ±16.61%) was similar to that of the controls (95.56 ±17.31%, P = .103). However, more SCA patients had lower IQ scores than controls though not statistically significant (P = 0.083). The overall academic performance of children with SCA, therefore, compares favorably with that of controls although there is a higher prevalence of poor performance among them.

    The finding of secretions and bolus pooling is of great diagnostic interest in the evaluation of subjects with swallowing disorders. Bedside evaluation alone, in subjects at risk for aspiration, can underestimate this parameter. The usefulness of endoscopic investigation for the evaluation of subjects with swallowing disorders is stressed, in order to plan treatment and follow-up. Based on endoscopic evaluation of material pooling we devised a score expressing the severity of dysphagia. This value takes into account endoscopic landmarks and other parameters of bedside evaluation. Endoscopic and bedside data were collected from a heterogeneous population of 520 consecutive patients seen in our Service over a 6-year period. By means of the test of equality of group means and logistic regression, parameters able to significantly predict aspiration in the series were identified. An ordinal number was attributed to each parameter in order to obtain scores expressing three degrees of severity of dysphagia: mild, moderate, severe. The scores can be used to guide the management of patients in a simple way, providing indications for targeted referral to the speech pathologist and for tracking the disorder over time. This investigation represents the basis for future research aimed at validating the scores in a larger case series.

    To validate the reliability of the visual coronary artery calcification score (VCACS) on low-dose CT (LDCT) for concurrent screening of CAC and lung cancer. We enrolled 401 subjects receiving LDCT for lung cancer screening and ECG-gated CT for the Agatston score (AS). LDCT was reconstructed with 3- and 5-mm slice thickness (LDCT-3mm and LDCT-5mm respectively) for VCACS to obtain VCACS-3mm and VCACS-5mm respectively. After a training session comprising 32 cases, two observers performed four-scale VCACS (absent, mild, moderate, severe) of 369 data sets independently, the results were compared with four-scale AS (0, 1-100, 101-400, >400). CACs were present in 39.6 % (146/369) of subjects. The sensitivity of VCACS-3mm was higher than for VCACS-5mm (83.6 % versus 74.0 %). The median of AS of the 24 false-negative cases in VCACS-3mm was 2.3 (range 1.1-21.1). The false-negative rate for detecting AS {>=} 10 on LDCT-3mm was 1.9 %. VCACS-3mm had higher concordance with AS than VCACS-5mm (k = 0.813 versus k = 0.685). An extended test of VCACS-3mm for four junior observers showed high inter-observer reliability (intra-class correlation = 0.90) and good concordance with AS (k = 0.662-0.747). This study validated the reliability of VCACS on LDCT for lung cancer screening and showed that LDCT-3mm was more feasible than LDCT-5mm for CAD risk stratification. (orig.)

    The effect of visual arts interventions on development of empathy has not been quantitatively investigated. A study was conducted on the effect of a visual arts-based program on the scores of the Jefferson Scale for Physician Empathy (JSPE). A total of 110 clerks (n = 92) and first-year postgraduate residents (PGY1s) (n = 18) participating in the program were recruited into this study. The 4-hr program covered the subjects of learning to interpret paintings, interpreting paintings relating to medicine, illness and human suffering, the related-topics of humanitarianism and the other humanities fields and values and meaning. The JSPE was completed at the beginning (pretest) and the end (posttest) of the program. There was no significant difference between the pretest and posttest JSPE scores. The average of the scores for the pretest was lower in the subgroup of PGY1s than the subgroup of clerks (p = 0.0358). An increased but not significantly mean posttest JESPE score was noted for the subgroup of PGY1s. Neither the females nor the males had higher posttest JSPE scores than the pretest scores. Although using a structured visual arts-based program as an intervention may be useful to enhance medical students' empathy, our results failed to show a positive effect on the JSPE Scores for a group of clerks and PGY1s. This suggests that further experimental studies are needed if quantitative evaluation of the effectiveness of visual-arts based programs on empathy is to be investigated.

    In previous studies event-related potentials and oscillations in response to subject's own name have been analyzed extensively on group-level in healthy subjects and in patients with a disorder of consciousness. Subject's own name as a deviant produces a P3. With equiprobable stimuli, non-phase-locked alpha oscillations are smaller in response to subject's own name compared to other names or subject's own name backwards. However, little is known about replicability on a single-subject level. Seventeen healthy subjects were assessed in an own-name paradigm with equiprobable stimuli of subject's own name, another name, and subject's own name backwards. Event-related potentials and non-phase locked oscillations were analyzed with single-subject, non-parametric statistics. No consistent results were found either for ERPs or for the non-phase locked changes of oscillatory activities. Only 4 subjects showed a robust effect as expected, that is, a lower activity in the alpha-beta range to subject's own name compared to other conditions. Four subjects elicited a higher activity for subject's own name. Thus, analyzing the EEG reactivity in the own-name paradigm with equiprobable stimuli on a single-subject level yields a high variance between subjects. In future research, single-subject statistics should be applied for examining the validity of physiologic measurements in other paradigms and for examining the pattern of reactivity in patients.

    Cognitive evaluation of young subjects is now widely carried out for non-traumatic diseases such as multiple sclerosis, HIV, or sleep disorders. This evaluation requires normative data based on healthy adult samples. However, most clinicians use a set of tests that were normed in an isolated manner from different samples using different cutoff criteria. Thus, the score of an individual may be considered either normal or impaired according to the norms used. It is well established that healthy adults obtained low-test scores when a battery of tests is administered. Thus, the knowledge of low base rates is required so as to minimize false diagnosis of cognitive impairment. The aim of this study was twofold (1) to provide normative data for RAPID-II battery in healthy adults, and (2) estimate the proportion of healthy adults having low scores across this battery. Norms for the 44 test scores of the RAPID-II test battery were developed using the overall sample of 335 individuals based on three categories of age (20 to 29, 30 to 39, and 40 to 49 years) and two educational levels: Baccalaureate or higher educational degree (high educational level), lower than baccalaureate (low educational level). The 5th, 25th, 50th, and 75th percentiles were calculated from the six age and education subsamples and used to define norms. The frequency of low scores on the RAPID-II battery was calculated by simultaneously examining the performance of 33 primary scores. A low score was defined as less than or equal to the 5th percentile drawn from the six age and education normative subsamples. In addition, the percentages of low scores were also determined when all possible combinations of two-test scores across the RAPID-II were considered in the overall normative sample. Our data showed that 59.4% subjects of the normative sample obtained at least one or more low score. With more than 9 test scores, this percentage was equal to 0% in the normative sample.

    There are conflicting data as to whether general or abdominal obesity is a better predictor of cardiovascular risk. This cross-sectional study involved 4,573 subjects aged 30 to 74 yr who participated in the Fourth Korea National Health and Nutrition Examination Survey conducted in 2008. Obesity phenotype was classified by means of body mass index (BMI) and waist circumference (WC), and participants were categorized into 4 groups. Individuals' 10-yr risk of coronary heart diseases (CHD) was determined from the Framingham risk score. Subjects with obese WC had a higher proportion of high risk for CHD compared to the normal WC group, irrespective of BMI level. Relative to subjects with normal BMI/normal WC, the adjusted odds ratios (ORs) of normal BMI/obese WC group (OR 2.93 [1.70, 5.04] and OR 3.10 [1.49, 6.46]) for CHD risk in male were higher than obese BMI/obese WC group (OR 1.91 [1.40, 2.61] and OR 1.70 [1.16, 2.47]), whereas the adjusted ORs of obese BMI/obese WC group (OR 1.94 [1.24, 3.04] and OR 3.92 [1.75, 8.78]) were higher than the others in female. Subjects with obese BMI/normal WC were not significantly associated with 10-yr CHD risk in men (P = 0.449 and P = 0.067) and women (P = 0.702 and P = 0.658). WC is associated with increased CHD risk regardless of the level of BMI. Men with normal BMI and obese WC tend to be associated with CHD risk than those with obese BMI and obese WC.

  4. Polygenic risk score predicts prevalence of cardiovascular disease in patients with familial hypercholesterolemia.

    Although familial hypercholesterolemia (FH) is a severe monogenic disease, it has been shown that clinical risk factors and common genetic variants can modify cardiovascular disease (CVD) risk. The aim of the study was to evaluate the polygenic contribution to lipid traits and CVD in FH using genetic risk scores (GRSs). Among the 20,434 subjects attending the lipid clinic, we identified and included 725 individuals who carried an FH causing mutation in this retrospective cohort study. We evaluated the association of GRSs for several traits including coronary artery disease (CAD; GRSCAD) as well as plasma concentrations of low-density lipoprotein cholesterol (LDL-C; GRSLDL-C), high-density lipoprotein cholesterol (GRSHDL-C) and triglycerides (GRSTG). A total of 32% (n = 231) of FH subjects presented a CVD event before their first visit. Patients in the highest GRSLDL-C tertile presented an LDL-C 0.4 mmol/L (15.5 mg/dL) higher than the subjects in the lowest tertile (P = .01). The GRSCAD was strongly associated with CVD events (odds ratio 1.80; 95% confidence interval 1.14-2.85; P = .01) even after adjustment for cardiovascular risk factors. Compared with subjects in the first tertile, those in the third GRSCAD tertile had a significantly higher prevalence of events (40.9% vs 24.7%, P < .0001) and a significantly higher number of events (average 0.97 vs 0.57 [P = .0001] events per individual). These results indicate that even in the context of a severe monogenic disease such as FH, common genetic variants can significantly modify the disease phenotype. The use of the 192-SNPs GRSCAD may refine CVD risk prediction in FH patients and this could lead to a more personalized approach to therapy. Copyright © 2017 National Lipid Association.

    Stimulants are the most effective drugs for attention-deficit/hyperactivity disorder (ADHD) symptoms. The purpose of this study was to explore the intervention effect of methylphenidate, a commonly used stimulant, on cognitive performance in ADHD children and whether the effect is associated with age, sex, different subtypes of ADHD, and drug dosage. Children with ADHD were divided into the following subtypes: combined type, predominantly inattentive type, and hyperactive/impulsive type. The intervention group consisted of 159 children treated with methylphenidate, and the control group consisted of 78 untreated patients. All 237 subjects were given a Wechsler Intelligence Scale for Children--Revised test at baseline, and 6 months later, they were retested. The scores of Verbal Intelligence Quotient (IQ) test, Performance IQ (PIQ) test, Full Scale IQ (FSIQ) test, and subtests were compared before and after the intervention. At baseline, scores were not statistically different between the 2 groups. After 6 months, PIQ and FSIQ scores of intervention group were higher than those of the control group (P intelligence.

    Schizophrenia is associated with brain structural abnormalities including gray and white matter volume reductions. Whether these alterations are caused by genetic risk variants for schizophrenia is unclear. Previous attempts to detect associations between polygenic factors for schizophrenia and structural brain phenotypes in healthy subjects have been negative or remain non-replicated. In this study, we used genetic risk scores that were based on the accumulated effect of selected risk variants for schizophrenia belonging to specific biological systems like synaptic function, neurodevelopment, calcium signaling, and glutamatergic neurotransmission. We hypothesized that this "biologically informed" approach would provide the missing link between genetic risk for schizophrenia and brain structural phenotypes. We applied whole-brain voxel-based morphometry (VBM) analyses in two population-based target samples and subsequent regions of interest (ROIs) analyses in an independent replication sample (total N = 2725). No consistent association between the genetic scores and brain volumes were observed in the investigated samples. These results suggest that in healthy subjects with a higher genetic risk for schizophrenia additional factors apart from common genetic variants (e.g., infection, trauma, rare genetic variants, or gene-gene interactions) are required to induce structural abnormalities of the brain. Further studies are recommended to test for possible gene-gene or gene-environment effects. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Purpose. The aim of this study was to assess whether the home care score (HCS), which was developed by the Ministry of Health and Welfare in Japan in 1992, is useful for the prediction of advisability of home care. Methods. Subjects living at home and in assisted-living facilities were analyzed. Binominal logistic regression analyses, using age, sex, the functional independence measure score, and the HCS, along with receiver operating characteristic curve analyses, were conducted. Findings/Conclusions. Only HCS was selected for the regression equation. Receiver operating characteristic curve analysis revealed that the area under the curve (0.9), sensitivity (0.82), specificity (0.83), and positive predictive value (0.84) for HCS were higher than those for the functional independence measure, indicating that the HCS is a powerful predictor for advisability of home care. Clinical Relevance. Comprehensive measurements of the condition of provided care and the activities of daily living of the subjects, which are included in the HCS, are required for the prediction of advisability of home care.

    Childhood obesity is a growing health challenge. Recent studies show that children with late bedtime and late awakening are more obese independent of total sleep time. In adolescents and adults, a delayed sleep phase has been associated with higher caloric intake. Furthermore, an adult study showed a positive correlation between REM sleep and energy balance. This relationship has not been demonstrated in children. However, it may be important as a delayed sleep phase would increase the proportion of REM sleep. This study investigated the relationship between hunger score and sleep physiology in a paediatric population. Thirty-six patients referred for a polysomnogram for suspected obstructive sleep apnoea were enrolled in the study. Sleep stages were recorded as part of the polysomnogram. Hunger scores were obtained using a visual analogue scale. Mean age was 9.6 ± 3.5 years. Mean hunger scores were 2.07 ± 2.78. Hunger scores were positively correlated with percentage of total rapid eye movement (REM) sleep (r = 0.438, P hunger score (r = -0.360, P hunger scores. These findings suggest that delayed bedtime, which increases the proportion of REM sleep and decreases the proportion of SWS, results in higher hunger levels in children. © 2015 World Obesity.

    Multiple scoring systems have been developed for both the intensive care unit (ICU) and the emergency department (ED) to risk stratify patients and predict mortality. However, it remains unclear whether the additional data needed to compute ICU scores improves mortality prediction for critically ill patients compared to the simpler ED scores. We studied a prospective observational cohort of 227 critically ill patients admitted to the ICU directly from the ED at an academic, tertiary care medical center. We compared Acute Physiology and Chronic Health Evaluation (APACHE) II, APACHE III, Simplified Acute Physiology Score (SAPS) II, Modified Early Warning Score (MEWS), Rapid Emergency Medicine Score (REMS), Prince of Wales Emergency Department Score (PEDS), and a pre-hospital critical illness prediction score developed by Seymour et al. (JAMA 2010, 304(7):747-754). The primary endpoint was 60-day mortality. We compared the receiver operating characteristic (ROC) curves of the different scores and their calibration using the Hosmer-Lemeshow goodness-of-fit test and visual assessment. The ICU scores outperformed the ED scores with higher area under the curve (AUC) values (p = 0.01). There were no differences in discrimination among the ED-based scoring systems (AUC 0.698 to 0.742; p = 0.45) or among the ICU-based scoring systems (AUC 0.779 to 0.799; p = 0.60). With the exception of the Seymour score, the ED-based scoring systems did not discriminate as well as the best-performing ICU-based scoring system, APACHE III (p = 0.005 to 0.01 for comparison of ED scores to APACHE III). The Seymour score had a superior AUC to other ED scores and, despite a lower AUC than all the ICU scores, was not significantly different than APACHE III (p = 0.09). When data from the first 24 h in the ICU was used to calculate the ED scores, the AUC for the ED scores improved numerically, but this improvement was not statistically significant. All scores had acceptable

    The purpose was to compare glucose variability (GV) obtained via continuous glucose monitoring between nondiabetic sepsis patients and healthy subjects and to seek associations between GV and sepsis severity in nondiabetic sepsis patients. Nondiabetic sepsis inpatients and healthy controls received a 72-hour continuous glucose monitoring (iPro2, Medtronic) postadmission and post-oral glucose tolerance test, respectively. The mean glucose level (MGL) along with GV represented by standard deviation (SD) and the mean amplitude of glycemic excursion (MAGE) were calculated at 24 and 72 hours. Sepsis severity was evaluated with the Sepsis-related Organ Failure Assessment Score (SOFA). MGL and GV in patients with SOFA ≥9 and sepsis and 10 healthy subjects were recruited. No differences were found between groups except for higher patient age in sepsis patients. The MGL and MAGE 72h of sepsis patients were significantly higher than those of healthy subjects. MGL and GV 24h were higher in patients with SOFA ≥9 than in patients with SOFA sepsis patients had higher MGL and GV values than healthy subjects. MGL and GV 24h were associated with sepsis severity.

    Study Type - Prognosis (case series) Level of Evidence 4. What's known on the subject? and What does the study add? There is limited data that suggests that men aged >70 years have a higher proportion of Gleason 8-10 prostate cancer than men aged Gleason score 6 and 7 prostate cancer have an increased risk of prostate cancer-specific mortality. This may be due to the presence of occult high-grade disease and suggests further diagnostic studies, e.g. multiparametric MRI, may be indicated in these men to reduce biopsy sampling error. To determine if advancing age is a risk factor for high-grade prostate cancer due to occult high-grade disease in elderly men with Gleason score 6 or 7 prostate cancer. We investigated whether advancing age is associated with the risk of prostate cancer-specific mortality (PCSM) within established Gleason score categories adjusting for known predictors of PCSM. Using data from the Surveillance, Epidemiology and End Results database between 1 January 2004 to 31 December 2007, 166 104 men with non-metastatic prostate cancer were identified and formed the study cohort. • Within established Gleason score categories, Fine and Gray's multivariable competing risk regressions were used to evaluate whether increasing age at diagnosis was significantly associated with an increased risk of PCSM, adjusting for prostate-specific antigen level and T-category at diagnosis and whether treatment was curative or non-curative. After adjusting for treatment and prognostic factors, Gleason score 8-10 and 7 as compared with ≤6 was associated with an increased risk of PCSM (P Gleason score 6 (adjusted hazard ratio [AHR] 1.06, 95% confidence interval [CI] 1.04-1.08, P Gleason score 8-10 (AHR 0.999, 95% CI 0.995-1.003, P= 0.61). • These risks were highest in men aged >70 years having Gleason score 6 (AHR 1.10, 95% CI 1.07-1.13, P Gleason score 7 prostate cancer (AHR 1.04, 95% CI 1.02-1.06, P Gleason score 6 and 7 but not 8-10 prostate cancer.

    Full Text Available BackgroundDiabetes mellitus is a chronic disease and one of the main causes of mortality in developing countries. The main objective of treating all chronic diseases, of course, is to improve well-being and attain a satisfactory quality of life (QOL. The major goal of this study is comparison of attitude toward QOL in insulin-dependent subjects with diabetes mellitus and healthy subjects.MethodsIn this study, insulin-dependent subjects with diabetes mellitus and healthy subjects were gathered via convenience sampling. The subjects were asked to complete the Hanestad & Albrektsen Attitude to Quality of Life Questionnaire. The questionnaire evaluates five quality of life dimensions-physical, social, mental-emotional, behavioral-activity, and economic-using a scoring system similar to the Likert scale. The Wilcoxon test was used to compare scores between the two groups.ResultsThe mean total score on attitude toward QOL in the healthy control group was 53.8, and it in the insulin-dependent subjects with diabetes mellitus group was 35.9. The mean total score of attitude toward QOL in the physical dimension, mental-emotional and feelings of well-being dimension, and behavioral-activity dimension were significantly higher in the healthy population than they were in diabetes mellitus groups. Such a difference was not seen in the social and economic dimensions.ConclusionSince the attitudes of insulin-dependent subjects with diabetes mellitus toward QOL are used as an index of individual and societal health levels, it appears that this group may benefit from education and professional counseling to improve their QOLs.

    Clinical prediction rules form an integral component of guidelines on the diagnostic approach to pulmonary embolism (PE). The Wells Score is commonly used but is subjective, while the newer Revised Geneva Score is based entirely on objective variables. The aim of this study was to compare the diagnostic accuracy of the Wells and Revised Geneva Scores for the diagnosis of PE. Patients presenting to the emergency department with clinically suspected PE and referred for CT pulmonary angiogram or ventilation/perfusion scintigraphy were evaluated. The Wells and Revised Geneva Scores were calculated on the same cohort of patients and dichotomized into low and intermediate/high probability groups. The sensitivities and specificities were compared using McNemar's test. Overall accuracy was determined using receiver operator characteristic curve analysis. A total of 98 consecutive patients was included. The overall prevalence of PE was 15.3%. The frequency of PE in the low, intermediate and high probability groups was similar for both clinical prediction rules. Compared with the Revised Geneva Score, the Wells Score showed a lower sensitivity with borderline significance (46.7% vs 80.0%, P= 0.06) and a significantly higher specificity (67.5% vs 47.0%, P= 0.002). The overall accuracy of both rules was similar (P= 0.617). Using the accepted guidelines in which a high pretest probability leads to further imaging and a low probability leads to a D-dimer blood test, use of the more specific Wells Score could safely reduce the number of unnecessary scans. This would need to be confirmed with larger, prospective trials. © 2011 The Authors. Internal Medicine Journal © 2011 Royal Australasian College of Physicians.

    Full Text Available Abstract Translational medicine describes the transfer of basic in vitro and in vivo data into human applications. In the light of low rates of market approvals for new medical entities, better strategies to predict the risk of drug development should be used to increase output and reduce costs. Recently, a scoring system to assess the translatability of early drug projects has been proposed. Here eight drugs from different therapeutic areas have been subjected to a retrospective test-run in this system fictively located at the phase II-III transition. The scores gained here underline the importance of biomarker quality which is pivotal to decrease the risk of the project in all cases. This is particularly evident for gefitinib. The EGFR mutation status is a breakthrough biomarker to predict therapeutic success which made this compound clinically acceptable, and this is plausibly reflected by a considerable increase of the translatability score. For psychiatric and Alzheimer's drugs, and for a CETP-inhibitor, the lack of suitable biomarkers and animal models is reflected by a low translatability score, well correlating with the excessive translational risk in these areas. These case studies document the apparent utility of the scoring system, at least under retrospective conditions, as the scores correlate with the outcomes at the level of market approval. Prospective validation is still missing, but these case studies are encouraging.

    Full Text Available Abstract Background Prediction of antigenic epitopes on protein surfaces is important for vaccine design. Most existing epitope prediction methods focus on protein sequences to predict continuous epitopes linear in sequence. Only a few structure-based epitope prediction algorithms are available and they have not yet shown satisfying performance. Results We present a new antigen Epitope Prediction method, which uses ConsEnsus Scoring (EPCES from six different scoring functions - residue epitope propensity, conservation score, side-chain energy score, contact number, surface planarity score, and secondary structure composition. Applied to unbounded antigen structures from an independent test set, EPCES was able to predict antigenic eptitopes with 47.8% sensitivity, 69.5% specificity and an AUC value of 0.632. The performance of the method is statistically similar to other published methods. The AUC value of EPCES is slightly higher compared to the best results of existing algorithms by about 0.034. Conclusion Our work shows consensus scoring of multiple features has a better performance than any single term. The successful prediction is also due to the new score of residue epitope propensity based on atomic solvent accessibility.

    No prior studies have evaluated whether residents who pursue fellowship training achieve higher performance on the Otolaryngology Training Examination (OTE) and whether a specific fellowship will demonstrate a correlation with the corresponding specialty-specific OTE score. To determine whether residents pursuing fellowship training achieve higher performance on the OTE and whether fellowship choice is correlated with higher scores on the related subspecialty section of the OTE. This retrospective analysis included 35 residents training in an academic otolaryngology residency program from July 1, 2003, to June 30, 2014. The OTE scores for postgraduate years 2 through 5 and the type of fellowship were collected for all residents meeting inclusion criteria. Data were collected from September 1 to October 15, 2014, and analyzed from October 16 to December 1, 2014. Residents were divided by whether they pursued fellowship training and by the type of fellowship chosen. Outcome measures included comparison of scores between residents who pursued vs those who did not pursue fellowship training and comparison of subspecialty OTE scores between residents who pursued the corresponding fellowship and those who did not. Of the 35 residents who met the inclusion criteria (24 men and 11 women), 17 (49%) pursued fellowship training. The 3 most common fellowship choices were facial plastic and reconstructive surgery, pediatric otolaryngology, and rhinology (4 residents each [24%]). For all residents, mean scores on the OTE improved each subsequent training year, but this difference was only significant between postgraduate years 2 and 3 (from 60.9% to 68.6% correct; P otolaryngology, 72.9% vs 71.3% [P = .79]; and for rhinology, 72.2% vs 71.2% [P = .91]). Residents who pursued fellowship training did not achieve higher scores on the OTE in any examination year compared with residents who did not pursue fellowship training and did not achieve higher scores within the OTE

    Subjective experiences are subtle, self-experienced disturbances, a thorough description of which is provided within the framework of the concept of basic symptoms. Recent studies have shown that subjective experiences have important diagnostic implications for schizophrenia and related disorders. The purpose of the present study was to examine the relationship between subjective experiences and psychopathological dimensions in schizophrenia. Sixty-seven outpatients with schizophrenia were evaluated. Subjective experiences were comprehensively assessed using the Frankfurt Complaint Questionnaire (FCQ). Symptoms of schizophrenia were evaluated using the Manchester Scale (MS). Pearson's partial correlation analysis was performed between the FCQ and the MS scores, controlling for the influence of extrapyramidal adverse effects. The analysis revealed that the MS positive symptom score had significant positive correlations with the FCQ total score and subscales scores. The MS negative symptom score did not have significant correlations with the FCQ scores. The results of our study suggest that subjective experiences are significantly associated with positive symptomatology in schizophrenia, suggesting that they may share a common underlying neural basis. Future prospective studies are necessary to confirm the stability of these relationships and to explore the diagnostic and therapeutic implications of subjective experiences in a diverse group of patients at different stages of illness.

Usually teaching grammar was boring and has the same way to learn like change the pattern of sentence into positive, negative and introgative while the students’ need more various way to develop their thinking. The outcome of students’ competence in grammar sometimes not sufficient enough when the students’ occured some test international standart like Test of English Foreign Language, International English Language Testing. Whereas in TOEFL test it needed higher order thinking answer, so teacher should develop students’ higher order thingking in daily teaching grammar in order to make the students’ enhance their thinking are higher. The method was used in this paper by using field study based on the experience of teaching grammar. It can be shown by students’ toefl score was less in stucture and written expression. The result of this paper was after teacher gave some treatments to enhance students’ higher order thinking in teaching grammar, the students’ toefl scores are sufficient enough as a part of stucture and written expression. It can concluded that it needed some strategies to enhancce students higher order thinking by teaching grammar it can make students’ higher toefl score. Teachers should be creative and inovative to teach the students’ started from giving the students’ question or test in teaching grammar.

    Full Text Available The contribution of modern science to the progress of civilization is immeasurable. Even its tendency toward exclusive concentration on the objective world has had salutary effects of great value. Modern science has wiped away much that was merely superstitious or speculative. Its rejection of unfounded opinions and prejudices has helped the thinking mind question conventional beliefs, shed preferences and prejudices, and challenge established authority. But modern systems thinking inherited from natural science is the suppression of the subjective dimension of reality. Many complex systems are an attempt to define and represent all subjective experience in physical terms. The modern man has a bias towards objectivity. The powerful influence of sense impressions on his mind and thinking makes him ignore the subjective experience and consider only objective facts as a valid, legitimate and representation of reality. Observing objective factors that are physical is easier than observing subjective factors that are subtle. The mechanistic view of reality has led to the rejection of the role of the individual in social development as insignificant. The individuals determine the development of society. Their social power has its roots both in subjective factors and objective factors. Economy, politics, society, and culture are inseparable dimensions of a single integrated reality. Subject and object constitute an integrated whole. The mind sees them as separate and independent. Or it views one as completely subordinate to the other. Unbiased approach to the study of all human experiences may prove that subject and object are interdependent dimensions or elements of reality.

    As well as being a very common neurological disease worldwide, epilepsy significantly impairs patients' emotional, behavioral, and cognitive functioning. Sleep disturbances are the most frequent complaint in patients with epilepsy. The present study assesses the impact of a range of affective symptoms on subjective sleep quality and sleep disturbances in Chinese adults with epilepsy. Adults with epilepsy who visited our epilepsy clinic from July 2015 to March 2016 were enrolled in our study. Both patients and healthy controls completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and Mini-mental State Examination (MMSE). Subjective sleep quality and sleep disturbances were examined with regard to self-reported symptoms of depression and anxiety, seizure-related factors, and demographic factors. The PSQI scores and ISI scores of patients were significantly higher (indicating lower quality sleep and more serious insomnia) than those of the control group. Symptoms associated with depression and anxiety were independently related to impaired subjective sleep quality and insomnia. Affective symptoms explained more of the variance in PSQI scores and ISI scores than did seizure-related or demographic variables. In addition, these variables also seemed to be less powerful contributing factors to subjective sleep quality and insomnia than affective symptoms, several seizure-related factors, such as seizure control, partial seizures and duration of epilepsy, which are also significantly associated with subjective sleep quality and insomnia. In addition, use of lamotrigine (LTG) was also associated with insomnia and use of clonazepam (CZP) and phenobarbital (PB) with daytime sleepiness in patients with epilepsy. Chinese adults with epilepsy have poorer self-reported subjective sleep quality and a higher prevalence of insomnia than the control group

    The Glans-Urethral Meatus-Shaft (GMS) score is a concise and reproducible way to describe hypospadias severity. We classified boys undergoing primary hypospadias repair to determine the correlation between GMS score and postoperative complications. Between February 2011 and August 2013, patients undergoing primary hypospadias repair were prospectively scored using the GMS classification. GMS scoring included a 1-4 scale for each component: G - glans size/urethral plate quality, M - meatal location, and S - degree of shaft curvature, with more unfavorable characteristics assigned higher scores [Figure]. Demographics, repair type, and complications (urethrocutaneous fistula, meatal stenosis, glans dehiscence, phimosis, recurrent chordee and stricture) were assessed. Total and individual component scores were tested in uni- and multivariate analysis. Two-hundred and sixty-two boys (mean age 12.3 ± 13.7 months) undergoing primary hypospadias repair had a GMS score assigned. Mean GMS score was 7 ± 2.5 (G 2.1 ± 0.9, M 2.4 ± 1, S 2.4 ± 1). Mean clinical follow-up was 17.7 ± 9.3 months. Thirty-seven children (14.1%) had 45 complications. A significant relationship between the total GMS score and presence of any complication (p hypospadias (GMS 3-6) had a 2.4% fistula rate vs. 11.1% for moderate (GMS 7-9) and 22.6% for severe (GMS 10-12) hypospadias (p 60° ventral curvature) patients were 27 times more likely to develop a fistula than S1 (no curvature) boys (95% CI, 3.2-229). The GMS score is based on anatomic features (i.e. glans size/urethral plate quality, location of meatus, and degree of chordee) felt to most likely impact functional and cosmetic outcomes following hypospadias repair. We demonstrated a statistically significant increase in the likelihood of any postoperative complication with every unit increase in total GMS score. The concept that factors aside from meatal location affect hypospadias repair and outcomes is not novel, and degree of ventral

    There is a deficit of reliable epidemiologic studies exploring the prevalence of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). Recent data suggests that occupational dust exposure may be involved in its physiopathology. To compare the prevalence of nasal polyposis (NP) in a group of workers with occupational dust exposure (textile workers) and in a control group (retail store workers). Cross-sectional study with a random sample of textile and retail store employees. Clinical data was gathered through a systematic interview, which included RhinoQOL and CAT questionnaires. A systematic endoscopic nasal examination was performed using a 0 degree rigid endoscope. Lund-Kennedy endoscopic score was determined for each participant. Statistical analysis was performed with SPSS. 316 participants were included in the study, i.e. 215 textile workers and 101 retail store workers. NP was found in 19 subjects among textile workers and none in the control group. The prevalence of NP increased by age strata and by years of dust exposition. Polypoid degeneration of the middle turbinate was more prevalent in the exposed group with Lund-Kennedy scoring also higher. RhinoQOL and CAT questionnaires had both significantly higher scores among textile employees. Previous medical diagnosis of atopic diseases or chronic lower airway diseases did not differ between exposed and control groups or even between subjects with and without NP. These results point to an important correlation between occupational dust exposure and NP occurrence.

    The relationship between mean control scores and mean experimental scores in 23 experiments on alignment illusions has been examined. Evidence is presented to show that, through the operation of the range effect, control scores are biased to a significant degree in the direction of experimental scores. The implications of this are considered, not only as regards the value of control scores in psychophysical studies, but also as further evidence of the dangers of within-subjects experimental designs when issues depend upon the values of extreme points in a range of values.

    Many elderly complain about their memory and undergo dementia screening by the Mini-Mental State Examination (MMSE). While objective memory impairment always precedes Alzheimer dementia (AD) it is unclear whether subjective memory complaints are predicting AD. We tried to answer this question in a prospective cohort study. The 75-years old non-demented inhabitants of Vienna-Transdanube were investigated for conversion to AD after 30 months. The predictive value of subjective memory complaints was analysed in two groups: subjects with high MMSE-score (28-30) and subjects with low MMSE-score (23-27). Only in subjects with high MMSE univariate analyses showed an association between subjective memory complaints and incident AD. In both groups the verbal memory test was the main predictor of AD in multivariate analyses. We suggest to perform memory testing in subjects complaining about memory irrespective of their performance in a screening procedure like the MMSE.

    To test the psychometric properties of the International Prostate Symptom Score (Hong Kong Chinese version 2) (IPSS) in Chinese male patients with benign prostatic hyperplasia (BPH) under secondary care. A prospective longitudinal study was done by interviewing subjects at baseline, at 2 week after baseline for assessing test-retest reliability and at 26 week after baseline for assessing responsiveness. All subjects were interviewed to complete a structured questionnaire including IPSS, Short Form-12 Health Survey version 2 (SF-12v2) and Depression Anxiety Stress Scale (DASS). The IPSS HRQOL score had weak correlations with SF-12v2 summary and DASS domain scores. For reliability analysis, Cronbach's alpha coefficient was 0.90 for the seven symptom-related items. The intraclass correlation coefficients of the IPSS total symptom score and HRQOL score were 0.90 and 0.86, respectively. For sensitivity, statistically significant differences were detected between the subjects with BPH and those without for IPSS total symptom score (effect size = 0.68) but not the IPSS HRQOL score. The areas under ROC curves for the IPSS total symptom and HRQOL scores were 0.67 and 0.60, respectively. The IPSS was valid, reliable instrument in Chinese patients with BPH. The IPSS total symptom score, but not the HRQOL score, is sensitive in differentiating subgroups.

    The present aim was to estimate the internal reliability and convergent validity of the Depression-Happiness Scale. Internal reliability was .90, and higher scores on the Depression-Happiness Scale were associated with more internal control (.28), higher self-esteem (.36), and lower trait anxiety (-.69) among 45 undergraduates at the University of Ulster. The results provide some evidence for the validation of the Depression-Happiness Scale as well as confirming previous research on the correlates of happiness.

    This U.S. Food and Drug Administration (FDA) laboratory study examines the impact of tablet splitting, the effect of tablet splitters, and the presence of a tablet score on the dose uniformity of two model drugs. Whole tablets were purchased from five manufacturers for amlodipine and six for gabapentin. Two splitters were used for each drug product, and the gabapentin tablets were also split by hand. Whole and split amlodipine tablets were tested for content uniformity following the general chapter of the United States Pharmacopeia (USP) Uniformity of Dosage Units , which is a requirement of the new FDA Guidance for Industry on tablet scoring. The USP weight variation method was used for gabapentin split tablets based on the recommendation of the guidance. All whole tablets met the USP acceptance criteria for the Uniformity of Dosage Units. Variation in whole tablet content ranged from 0.5 to 2.1 standard deviation (SD) of the percent label claim. Splitting the unscored amlodipine tablets resulted in a significant increase in dose variability of 6.5-25.4 SD when compared to whole tablets. Split tablets from all amlodipine drug products did not meet the USP acceptance criteria for content uniformity. Variation in the weight for gabapentin split tablets was greater than the whole tablets, ranging from 1.3 to 9.3 SD. All fully scored gabapentin products met the USP acceptance criteria for weight variation. Size, shape, and the presence or absence of a tablet score can affect the content uniformity and weight variation of amlodipine and gabapentin tablets. Tablet splitting produced higher variability. Differences in dose variability and fragmentation were observed between tablet splitters and hand splitting. These results are consistent with the FDA's concerns that tablet splitting can have an effect on the amount of drug present in a split tablet and available for absorption. Tablet splitting has become a very common practice in the United States and throughout the

    The present study was designed to explore psychopathological correlates of self-deception in clinical and nonclinical individuals to ascertain whether self-deception was associated with higher hopelessness, a proxy of suicide risk. The patients were 58 consecutive psychiatric patients (30 men, 28 women) admitted to the Sant'Andrea Hospital's psychiatric ward in Rome.

    Several scar-scoring scales exist to clinically monitor burn scar development and maturation. Although scoring scars through direct clinical examination is ideal, scars must sometimes be scored from photographs. No scar scale currently exists for the latter purpose. We modified a previously described scar scale (Yeong et al., J Burn Care Rehabil 1997) and tested the reliability of this new scale in assessing burn scars from photographs. The new scale consisted of three parameters as follows: scar height, surface appearance, and color mismatch. Each parameter was assigned a score of 1 (best) to 4 (worst), generating a total score of 3-12. Five physicians with burns training scored 120 representative photographs using the original and modified scales. Reliability was analyzed using coefficient of agreement, Cronbach alpha, intraclass correlation coefficient, variance, and coefficient of variance. Analysis of variance was performed using the Kruskal-Wallis test. Color mismatch and scar height scores were validated by analyzing actual height and color differences. The intraclass correlation coefficient, the coefficient of agreement, and Cronbach alpha were higher for the modified scale than those of the original scale. The original scale produced more variance than that in the modified scale. Subanalysis demonstrated that, for all categories, the modified scale had greater correlation and reliability than the original scale. The correlation between color mismatch scores and actual color differences was 0.84 and between scar height scores and actual height was 0.81. The modified scar scale is a simple, reliable, and useful scale for evaluating photographs of burn patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    2015-01-01

    The technical term "higher brain dysfunction" is used widely in Japan. However, it is not always clear what "higher" means. The author thinks that the term "higher" is understood as being associated with a meaning. In this article, the differences between higher brain dysfunctions and elementary brain dysfunctions are discussed from the point of view of lesion localization and the consistency of symptoms. The psychiatric approach is indispensable for the assessment of higher brain dysfunction. A simple test for mild Alzheimer-type dementia is also introduced.

  11. Direct power comparisons between simple LOD scores and NPL scores for linkage analysis in complex diseases.

    Abreu, P C; Greenberg, D A; Hodge, S E

    1999-09-01

    Several methods have been proposed for linkage analysis of complex traits with unknown mode of inheritance. These methods include the LOD score maximized over disease models (MMLS) and the "nonparametric" linkage (NPL) statistic. In previous work, we evaluated the increase of type I error when maximizing over two or more genetic models, and we compared the power of MMLS to detect linkage, in a number of complex modes of inheritance, with analysis assuming the true model. In the present study, we compare MMLS and NPL directly. We simulated 100 data sets with 20 families each, using 26 generating models: (1) 4 intermediate models (penetrance of heterozygote between that of the two homozygotes); (2) 6 two-locus additive models; and (3) 16 two-locus heterogeneity models (admixture alpha = 1.0,.7,.5, and.3; alpha = 1.0 replicates simple Mendelian models). For LOD scores, we assumed dominant and recessive inheritance with 50% penetrance. We took the higher of the two maximum LOD scores and subtracted 0.3 to correct for multiple tests (MMLS-C). We compared expected maximum LOD scores and power, using MMLS-C and NPL as well as the true model. Since NPL uses only the affected family members, we also performed an affecteds-only analysis using MMLS-C. The MMLS-C was both uniformly more powerful than NPL for most cases we examined, except when linkage information was low, and close to the results for the true model under locus heterogeneity. We still found better power for the MMLS-C compared with NPL in affecteds-only analysis. The results show that use of two simple modes of inheritance at a fixed penetrance can have more power than NPL when the trait mode of inheritance is complex and when there is heterogeneity in the data set.

    Clinical risk scores, CHADS2 and CHA2 DS2 -VASc scores, are the established tools for assessing stroke risk in patients with atrial fibrillation (AF). The aim of this study is to assess concordance between manual and computer-based calculation of CHADS2 and CHA2 DS2 -VASc scores, as well as to analyse the patient categories using CHADS2 and the potential improvement on stroke risk stratification with CHA2 DS2 -VASc score. We linked data from Atrial Fibrillation Spanish registry FANTASIIA. Between June 2013 and March 2014, 1318 consecutive outpatients were recruited. We explore the concordance between manual scoring and computer-based calculation. We compare the distribution of embolic risk of patients using both CHADS2 and CHA2 DS2 -VASc scores The mean age was 73.8 ± 9.4 years, and 758 (57.5%) were male. For CHADS2 score, concordance between manual scoring and computer-based calculation was 92.5%, whereas for CHA2 DS2 -VASc score was 96.4%. In CHADS2 score, 6.37% of patients with AF changed indication on antithrombotic therapy (3.49% of patients with no treatment changed to need antithrombotic treatment and 2.88% of patients otherwise). Using CHA2 DS2 -VASc score, only 0.45% of patients with AF needed to change in the recommendation of antithrombotic therapy. We have found a strong concordance between manual and computer-based score calculation of both CHADS2 and CHA2 DS2 -VASc risk scores with minimal changes in anticoagulation recommendations. The use of CHA2 DS2 -VASc score significantly improves classification of AF patients at low and intermediate risk of stroke into higher grade of thromboembolic score. Moreover, CHA2 DS2 -VASc score could identify 'truly low risk' patients compared with CHADS2 score. © 2016 Royal Australasian College of Physicians.

    Full Text Available INTRODUCTION: Greater adherence to a Mediterranean diet is linked to lower risk for cardiovascular morbidity/mortality in studies of Mediterranean cohorts, older subjects, and/or those with existing health conditions. No studies have examined the effects of this dietary pattern in younger working populations in the United States. We investigated the effects of Mediterranean diet adherence on cardiovascular disease (CVD biomarkers, metabolic syndrome and body composition in an occupationally active, non-Mediterranean cohort. METHODS: A cross-sectional study in a cohort of 780 career male firefighters, ages 18 years or older, from the United States Midwest. No dietary intervention was performed. A modified Mediterranean diet score (mMDS was developed for assessment of adherence to a Mediterranean dietary pattern from a previously administered life-style questionnaire that examined pre-existing dietary habits. Clinical data from fire department medical examinations were extracted and analyzed. RESULTS: Obese subjects had significantly lower mMDS, and they reported greater fast/take-out food consumption (p<0.001 and intake of sweetened drinks during meals (p = 0.002. After multivariate adjustment, higher mMDS was inversely related to risk of weight gain over the past 5 years (odds ratio [OR]: 0.57, 95% confidence interval [CI]: 0.39-0.84, p for trend across score quartiles: 0.01; as well as the presence of metabolic syndrome components (OR: 0.65, 95% CI: 0.44-0.94, p for trend across score quartiles: 0.04. Higher HDL-cholesterol (p = 0.008 and lower LDL-cholesterol (p = 0.04 were observed in those with higher mMDS in linear regression after multivariate adjustment for age, BMI and physical activity. CONCLUSIONS: In a cohort of young and active US adults, greater adherence to a Mediterranean-style dietary pattern had significant inverse associations with metabolic syndrome, LDL-cholesterol and reported weight gain, and was significantly and

  15. PRSice: Polygenic Risk Score software.

    Science.gov (United States)

    Euesden, Jack; Lewis, Cathryn M; O'Reilly, Paul F

    2015-05-01

    A polygenic risk score (PRS) is a sum of trait-associated alleles across many genetic loci, typically weighted by effect sizes estimated from a genome-wide association study. The application of PRS has grown in recent years as their utility for detecting shared genetic aetiology among traits has become appreciated; PRS can also be used to establish the presence of a genetic signal in underpowered studies, to infer the genetic architecture of a trait, for screening in clinical trials, and can act as a biomarker for a phenotype. Here we present the first dedicated PRS software, PRSice ('precise'), for calculating, applying, evaluating and plotting the results of PRS. PRSice can calculate PRS at a large number of thresholds ("high resolution") to provide the best-fit PRS, as well as provide results calculated at broad P-value thresholds, can thin Single Nucleotide Polymorphisms (SNPs) according to linkage disequilibrium and P-value or use all SNPs, handles genotyped and imputed data, can calculate and incorporate ancestry-informative variables, and can apply PRS across multiple traits in a single run. We exemplify the use of PRSice via application to data on schizophrenia, major depressive disorder and smoking, illustrate the importance of identifying the best-fit PRS and estimate a P-value significance threshold for high-resolution PRS studies. PRSice is written in R, including wrappers for bash data management scripts and PLINK-1.9 to minimize computational time. PRSice runs as a command-line program with a variety of user-options, and is freely available for download from http://PRSice.info jack.euesden@kcl.ac.uk or paul.oreilly@kcl.ac.uk Supplementary data are available at Bioinformatics online. © The Author 2014.

    Low-grade inflammation is associated with an increased risk of chronic degenerative disease, but its relationship with mortality is less well explored. We aimed at evaluating, at a large epidemiological level, the possible association of low-grade inflammation, as measured by a composite score, with overall mortality risk. We conducted a population-based prospective investigation on 20,337 adult subjects free from major hematological disease and acute inflammatory status, randomly recruited from the general population of the Moli-sani study. A low-grade inflammation score was obtained from the sum of 10-tiles of plasmatic (C-reactive protein) and cellular (leukocyte and platelet counts, granulocyte/lymphocyte ratio) biomarkers of low-grade inflammation; higher levels indicated increased low-grade inflammation. Hazard ratios were calculated using multivariable Cox proportional hazard models with 95% confidence intervals. At the end of follow-up (median 7.6 years), 837 all-cause deaths were recorded. As compared to subjects in the lowest quartile of the low-grade inflammation score, those in the highest category had a significantly increased risk in overall mortality (HR=1.44; 1.17-1.77), independently of possible confounders, including the presence of chronic diseases and a number of health-related behaviors. The magnitude of the association of low-grade inflammation with mortality was relatively higher in type 2 diabetic patients (HR=2.90; 1.74-4.84) and in individuals with a history of cardiovascular disease (HR=2.48; 1.50-4.11) as compared to their counterparts who were free from the disease. In conclusion, an elevated degree of low-grade inflammation, as measured by a composite score of inflammatory biomarkers, is an independent risk factor for total mortality in an apparently healthy adult general population.

    Conclusion: Syntax score has the ability to predict the occurrence of PMI with accepted sensitivity. It can assess the patient risk for development of PMI which could help to rationalize the use of adjunctive therapies as distal embolic protection devices in high risk patients. Also, diabetic patients have higher incidence of complicated coronary lesions, higher syntax score and they are more labile for PMI.

    The Wilkins score and commissural calcification scores predict outcomes after percutaneous balloon mitral valvuloplasty. However, many cardiologists are inadequately trained in their application-both in the United States where the incidence of rheumatic heart disease has fallen and in rheumatic heart disease endemic countries where training infrastructure is weak. This study sought to develop a computer-based educational module teaching 2 scoring systems for rheumatic mitral stenosis and to validate the module among cardiology fellows in the United States and Uganda. We developed a module organized into 3 sets of 10 echocardiograms each. The module was completed by 13 cardiology fellows from 2 academic centers in the United States and 1 in Uganda. Subject answers were compared with a score assigned by 2 experts in echocardiography. The primary outcome was change in subjects' accuracy from set 1 to set 3, measured by mean absolute deviation from expert scores. Secondary outcomes included change in interoperator variability and individual subject bias from set 1 to set 3. The mean absolute deviations from expert scores in sets 1 and 3 were 2.09 and 1.82 for the Wilkins score (possible score range 0 to 16) and 1.13 and 0.94 for the commissural calcification score (possible score range 0 to 4). The change from set 1 to set 3 was statistically significant only for 1 of the Wilkins component scores (leaflet calcification, p < 0.001.) No change was seen in the interoperator variability. Individual subject bias in assigning the total Wilkins score was reduced from set 1 to set 3. Use of this module has the potential to enhance the training of cardiologists in the echocardiographic assessment of mitral stenosis. Modified versions of this module or similar ones should be tested in targeted populations of cardiology trainees with the most exposure to mitral stenosis interventions.

    2012-05-01

    Full Text Available Objectives. To examine the relationship between “traditional Sami” dietary pattern and mortality in a general northern Swedish population. Study design . Population-based cohort study. Methods. We examined 77,319 subjects from the Västerbotten Intervention Program (VIP cohort. A traditional Sami diet score was constructed by adding 1 point for intake above the median level of red meat, fatty fish, total fat, berries and boiled coffee, and 1 point for intake below the median of vegetables, bread and fibre. Hazard ratios (HR for mortality were calculated by Cox regression. Results. Increasing traditional Sami diet scores were associated with slightly elevated all-cause mortality in men [Multivariate HR per 1-point increase in score 1.04 (95% CI 1.01–1.07, p=0.018], but not for women [Multivariate HR 1.03 (95% CI 0.99–1.07, p=0.130]. This increased risk was approximately equally attributable to cardiovascular disease and cancer, though somewhat more apparent for cardiovascular disease mortality in men free from diabetes, hypertension and obesity at baseline [Multivariate HR 1.10 (95% CI 1.01–1.20, p=0.023]. Conclusions. A weak increased all-cause mortality was observed in men with higher traditional Sami diet scores. However, due to the complexity in defining a “traditional Sami” diet, and the limitations of our questionnaire for this purpose, the study should be considered exploratory, a first attempt to relate a “traditional Sami” dietary pattern to health endpoints. Further investigation of cohorts with more detailed information on dietary and lifestyle items relevant for traditional Sami culture is warranted.

    Gorji, Mohammad Ali; Mansoori, Seyed Ali Hosseini; Firouzjahi, Hassan

    2018-01-01

    We study cosmological perturbations in mimetic gravity in the presence of classified higher derivative terms which can make the mimetic perturbations stable. We show that the quadratic higher derivative terms which are independent of curvature and the cubic higher derivative terms which come from curvature corrections are sufficient to remove instabilities in mimetic perturbations. The classified higher derivative terms have the same dimensions but they contribute differently in the background and perturbed equations. Therefore, we can control both the background and the perturbation equations allowing us to construct the higher derivative extension of mimetic dark matter and the mimetic nonsingular bouncing scenarios. The latter can be thought as a new higher derivative effective action for the loop quantum cosmology scenario in which the equations of motion coincide with those suggested by loop quantum cosmology. We investigate a possible connection between the mimetic cosmology and the Randall-Sundrum cosmology.

    Full Text Available We propose a hybrid class of theories for higher spin gravity and matrix models, i.e., which handle simultaneously higher spin gravity fields and matrix models. The construction is similar to Vasiliev’s higher spin gravity, but part of the equations of motion are provided by the action principle of a matrix model. In particular, we construct a higher spin (gravity matrix model related to type IIB matrix models/string theory that have a well defined classical limit, and which is compatible with higher spin gravity in A d S space. As it has been suggested that higher spin gravity should be related to string theory in a high energy (tensionless regime, and, therefore to M-Theory, we expect that our construction will be useful to explore concrete connections.

    1993-01-01

    The main topic of the book is higher analytic microlocalization and its application to problems of propagation of singularities. The part on higher microlocalization could serve as an introduction to the subject. The results on propagation refer to solutions of linear partial differentialoperators with characteristics of variable multiplicity and are of conical refraction type. The relation and interplay between these results and results or constructions from geometrical optics in crystal theory is discussed with many details. The notes are written foremost for researchers working in microlocal analysis, but it is hoped that they can also be of interest for mathematicians and physicists who work in propagation phenomena from a more classical point of view.

    To evaluate the performance of a silicone hydrogel daily disposable lens in neophyte subjects over 12 months. Seventy four subjects with no previous contact lens experience were randomised to wear narafilcon A (1 DAY ACUVUE(®) TruEye™) lenses (LW group) or to wear no contact lenses (NLW group) for 12 months. Biomicroscopy (performed by a masked investigator), visual acuity and subjective response scores were recorded at an initial visit and six follow-up visits, in addition to lens fit and surface evaluation for the LW group. Comfort was recorded with SMS messaging. Fifteen of the LW group discontinued before the end of the study, compared with six of the NLW group. Measured visual acuity was about half a line better for the NLW group as these subjects were provided with their full sphero-cylindrical over-refraction, compared to the LW group in their best spherical corrected contact lenses; subjective scores for vision were similar for the two groups. Bulbar conjunctival hyperaemia, limbal hyperaemia, corneal staining, conjunctival staining and papillary conjunctivitis were clinically equivalent for the two groups whereas conjunctival staining was higher in the LW group. Comfort scores assessed by SMS were equivalent for the LW and NLW groups; there was a measurable improvement in comfort during the first month of wear for the LW group. This work has demonstrated that modern soft lenses (narafilcon A daily disposable silicone hydrogel lenses) offer an excellent, comfortable form of vision correction, and are able to exhibit minimal alterations to ocular physiology.

The patients were divided in 4 groups by the delivery pattern: vaginal delivery with head presentation (2497 infants), vaginal delivery with instrumental assist (45 infants), per vias naturales in breech presentation (44 infants), delivery via Caesarean section (1038 infants). According to our results the Apgar score differs itself from the pathology of a given newborn. Neonatal deaths are significantly higher in the newborns with low Apgar score than deaths in the general population. From all cases of low Apgar score without other clinical problems the highest is the percentage in the infants delivered via Caesarean section. The goal of the Apgar score is to focus attention on the infant's condition in the first few minutes of its life and the need of resuscitation. Low Apgar score is an important predictor of the newborn morbidity and death rate. The Apgar score alone is not a proof for intrapartal asphyxia and is not associated with long-term neurological damage.

    The Apgar score provides an accepted and convenient method for reporting the status of the newborn infant immediately after birth and the response to resuscitation if needed. The Apgar score alone cannot be considered to be evidence of or a consequence of asphyxia, does not predict individual neonatal mortality or neurologic outcome, and should not be used for that purpose. An Apgar score assigned during a resuscitation is not equivalent to a score assigned to a spontaneously breathing infant. The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists encourage use of an expanded Apgar score reporting form that accounts for concurrent resuscitative interventions.

    Objective This study was designed to provide typical descriptive statistics, score distributions and percentile ranks of the Jefferson Scale of Empathy-Medical Student version (JSE-S) of male and female medical school matriculants to serve as proxy norm data and tentative cutoff scores. Subjects and Methods The participants were 2,637 students (1,336 women and 1,301 men) who matriculated at Sidney Kimmel (formerly Jefferson) Medical College between 2002 and 2012, and completed the JSE at the beginning of medical school. Information extracted from descriptive statistics, score distributions and percentile ranks for male and female matriculants were used to develop proxy norm data and tentative cutoff scores. Results The score distributions of the JSE tended to be moderately skewed and platykurtic. Women obtained a significantly higher mean score (116.2 ± 9.7) than men (112.3 ± 10.8) on the JSE-S (t2,635 = 9.9, p empathy. PMID:25924560

    The Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system, which quantifies a patient's reserve and surgical stress, is used to predict morbidity and mortality in patients before elective gastrointestinal surgery. We conducted this study to clarify whether the E-PASS scoring system is useful for assessing the risks of emergency abdominal surgery. The subjects of this retrospective study were 51 patients who underwent emergency gastrointestinal surgery at a public general hospital. The main outcomes were the E-PASS scores and the postoperative course, defined by mortality and morbidity. Postoperative complications developed in 15 of the 51 patients (29.4%). The E-PASS score was significantly higher in the patients with postoperative complications than in those without (0.61 ± 0.31 vs 0.20 ± 0.35, respectively; n = 36). The morbidity rates were significantly lower in the patients with a value less than 0.5 than in those with a value more than 0.5 (17.1% and 56.3%, respectively; P high score, versus none among the 9 patients with a low score (P surgery. Minimally invasive therapy would assist in lowering the risk of complications.

    The European Society of Cardiology guidelines for pulmonary embolism (PE) published in 2008 and updated in 2014 recommend a risk stratification including risk scores like Wells and the Geneva score. The utility and practicability of these scores are controversially discussed. Recently, in a trauma cohort and in spinal surgery patients, no correlation between Wells Score and PE diagnosis was found. The aim of the study was the evaluation of Wells and Geneva scores in patients presenting with chest pain, dyspnoea or syncope in an emergency department. We retrospectively examined 326 patients suspected of PE, including assessment, according to Wells and Geneva scores. PE was detected in 13.5 %. The average Wells score was 1.0, the average Geneva score 3.9. The receiver operating characteristic (ROC) curve analyses showed for both scores a high significant area under the curve (Wells score 0.68; Geneva score 0.64). The association between the scores and the diagnosis of PE was calculated with logistic regression analysis and showed high significant odds ratios (OR) for both scores (Wells score 1.38; Geneva score 1.24). There was no significant difference between the area under the curve (AUC) of Wells score and Geneva score.

    Full Text Available Aims. To develop a noninvasive score model to predict NASH in patients with combined CHB and NAFLD. Objective and Methods. 65 CHB patients with NAFLD were divided into NASH group (34 patients and non-NASH group (31 patients according to the NAS score. Biochemical indexes, liver stiffness, and Controlled Attenuation Parameter (CAP were determined. Data in the two groups were compared and subjected to multivariate analysis, to establish a score model for the prediction of NASH. Results. In the NASH group, ALT, TG, fasting blood glucose (FBG, M30 CK-18, CAP, and HBeAg positive ratio were significantly higher than in the non-NASH group (P<0.05. Multivariate analysis showed that CK-18 M30, CAP, FBG, and HBVDNA level were independent predictors of NASH. Therefore, a new model combining CK18 M30, CAP, FBG, and HBVDNA level was established using logistic regression. The AUROC curve predicting NASH was 0.961 (95% CI: 0.920–1.00, cutoff value is 0.218, with a sensitivity of 100% and specificity of 80.6%. Conclusion. A noninvasive score model might be considered for the prediction of NASH in patients with CHB combined with NAFLD.

  5. Higher dimensional higher derivative ϕ4 theory

    We construct several towers of scalar quantum field theories with an O (N ) symmetry which have higher derivative kinetic terms. The Lagrangians in each tower are connected by lying in the same universality class at the d -dimensional Wilson-Fisher fixed point. Moreover the universal theory is studied using the large N expansion and we determine d -dimensional critical exponents to O (1 /N2). We show that these new universality classes emerge naturally as solutions to the linear relation of the dimensions of the fields deduced from the underlying force-matter interaction of the universal critical theory. To substantiate the equivalence of the Lagrangians in each tower we renormalize each to several loop orders and show that the renormalization group functions are consistent with the large N critical exponents. While we focus on the first two new towers of theories and renormalize the respective Lagrangians to 16 and 18 dimensions there are an infinite number of such towers. We also briefly discuss the conformal windows and the extension of the ideas to theories with spin-1/2 and spin-1 fields as well as the idea of lower dimension completeness.

  6. Science of the subjective.

    Jahn, R G; Dunne, B J

    2007-01-01

    Over the greater portion of its long scholarly history, the particular form of human observation, reasoning, and technical deployment we properly term "science" has relied at least as much on subjective experience and inspiration as it has on objective experiments and theories. Only over the past few centuries has subjectivity been progressively excluded from the practice of science, leaving an essentially secular analytical paradigm. Quite recently, however, a compounding constellation of newly inexplicable physical evidence, coupled with a growing scholarly interest in the nature and capability of human consciousness, are beginning to suggest that this sterilization of science may have been excessive and could ultimately limit its epistemological reach and cultural relevance. In particular, an array of demonstrable consciousness-related anomalous physical phenomena, a persistent pattern of biological and medical anomalies, systematic studies of mind/brain relationships and the mechanics of human creativity, and a burgeoning catalogue of human factors effects within contemporary information processing technologies, all display empirical correlations with subjective aspects that greatly complicate, and in many cases preclude, their comprehension on strictly objective grounds. However, any disciplined re-admission of subjective elements into rigorous scientific methodology will hinge on the precision with which they can be defined, measured, and represented, and on the resilience of established scientific techniques to their inclusion. For example, any neo-subjective science, while retaining the logical rigor, empirical/theoretical dialogue, and cultural purpose of its rigidly objective predecessor, would have the following requirements: acknowledgment of a proactive role for human consciousness; more explicit and profound use of interdisciplinary metaphors; more generous interpretations of measurability, replicability, and resonance; a reduction of ontological

  7. Examining alternative scoring rubrics on a statewide test: The impact of different scoring methods on science and social studies performance assessments

    Creighton, Susan Dabney

    There is no consensus regarding the most reliable and valid scoring methods for the assessment of higher order thinking skills. Most of the research on alternative formats has focused on the scoring of writing ability. This study examined the value of different types of performance assessment scoring guides on state mandated science and social studies tests. A proportional stratified sample of raters were randomly assigned to one of four scoring groups: checklist, analytic rubric, holistic rubric, and generic rubrics. A fifth method, the weighted analytic rubric, was included by applying an algorithmic formula to the scores assigned by raters using the analytic rubric. A comparison of the mean scores for the five scoring groups suggests that there may be a difference in the way raters applied the rubric for each group. Although the literature suggests that it is possible to achieve high levels of inter-rater reliability, across forms of scoring, phi coefficients of moderate strength were obtained for three of the four constructed-response items. Results for each scoring group were compared indicating that item complexity may impact the level of inter-rate, reliability and the selection of the most reliable rubric for each discipline. Analytic rubrics appear to achieve more reliable results with less complex items. A multitrait-multimethod approach was utilized to investigate the external validity of the social studies and science tasks. As expected, there tended to be a stronger association between the PACT science constructed-response scores with scores based on science multiple-choice scores than between the science constructed-response scores and the writing ability subtest scores. A similar pattern was seen with social studies items. These results provide some evidence for the validity of the performance assessments. A post study survey completed by raters provided qualitative information regarding their thought processes and their primary focus during the

    2016-11-03

    This article describes a 3-year retrospective analysis of student clinical rotation evaluations using the Reporter-Interpreter-Manager-Educator (RIME) scoring format. The intent of the analysis was to assess scoring trends to determine whether students with high scores on the Physician Assistant National Certifying Exam (PANCE) also achieved high RIME scores on clinical rotations. The top and bottom quartiles of PANCE scores were identified for the University of Texas (UT) Southwestern Medical Center's physician assistant (PA) classes of 2010-2012 (n = 106). RIME scores for the top and bottom quartiles of students (n = 54) also were identified. RIME scores for the same cohort of students were analyzed using the top and bottom quartiles of students' PANCE scores. The Wilcoxon matched-pairs signed rank test revealed that students with top quartile PANCE scores received a higher aggregate RIME score of 557 compared with the lower quartile of PANCE performers' score of 520 (P < .03). Results for RIME scoring trends, PANCE scores, and end-of-rotation examination scores are presented. Students from the UT Southwestern Medical Center's PA classes of 2010-2012 obtained a Manager classification most often (52%), and students with higher PANCE scores also received higher RIME scores on clinical rotations.

    Drugs with anticholinergic properties may be associated with various adverse clinical effects. The relationship between the anticholinergic (AC) burden and functional, global cognitive performance and behavior disturbances was assessed among elderly patients. A cross-sectional study was conducted between January 2012 and June 2014 in a memory clinic among outpatients living at home and with subjective cognitive decline (SCD) or neurocognitive disorders (NCD). The AC burden was measured using the Anticholinergic Drug Scale (ADS), the Anticholinergic Risk Scale (ARS), the Anticholinergic Cognitive Burden (ACB), Chew's score, Han's score, and the number of drugs with AC activity. Functional, cognitive performance and behavior disturbances were assessed using the Instrumental Activities of Daily Living (IADL) scale (IADL), the Mini Mental State Examination (MMSE), and the Neuropsychiatric Inventory (NPI). Among 473 included patients, 46.3% were at major NCD. Patients took on average 5.3 ± 2.6 drugs. MMSE was lower when Han's score (p = 0.04) and number of AC drugs were higher (p drugs were higher. After adjustment, all AC scores remained associated with IADL, while Han's score and number of drugs with AC remained associated with the MMSE. In patients with SCD or NCD, AC burden is associated with lower functional score, whereas the cross-sectional association between AC burden and cognitive performance or behavioral disturbance varies according to AC scores. Particular attention should be paid when prescribing drugs with AC properties, especially among patients with memory complaints.

    The best system for organ allocation is still a controversial issue. The aim of this study was to study the accuracy of four different scores to predict mortality on the waiting list and, thus, their usefulness to determine organ allocation. We retrospectively compared two groups of patients, those who died on waiting list (group D) and those who successfully underwent transplantation (group T) during the same time period. Four scores, at the time of entering the waiting list and just before liver transplantation or death, were evaluated. The evaluated scores were as follows: (1) the Child-Pugh classification; (2) the Model for End-Stage Liver Disease (MELD) score; (3) the Freeman scale; and (4) the Guardiola et al index. The mortality rate on waiting list was 15.9%. All studied scores, except Freeman scale, were higher in group D at the time of entrance on waiting list (MELD, 17.4 +/- 8 v 12.3 +/- 6, P = .02; Child, 9.9 +/- 2 v 7.7 +/- 2, P = .002; Freeman, 9.7 +/- 4 v 7.3 +/- 3.9, P = .09; Guardiola, 2.6 +/- 0.9 v 1.7 +/- 0.7, P = .001). C-statistics of all scores were similar and in all cases lower than 0.8 (MELD, 0.75; Child, 0.78; Freeman, 0.65; Guardiola, 0.79). None of the studied scores have an excellent accuracy to predict prognosis of patients on waiting list, mainly in case of populations with high proportion of hepatocellular carcinoma. Although the MELD score is rapidly available, standardized, and objective, it does not reflect the severity of patients with cancer or metabolic disorders.

  18. The Association between Intelligence Scores and Family History of Psychiatric Disorder in Schizophrenia Patients, Their Siblings and Healthy Controls

    2013-01-01

    Background The degree of intellectual impairment in schizophrenia patients and their relatives has been suggested to be associated with the degree of familial loading for schizophrenia. Since other psychiatric disorders are also more present in relatives of schizophrenia patients, the definition of family history should be broadened. The association between family history for psychiatric disorder and intelligence scores was investigated in patients with non-affective psychosis, their unaffected siblings and controls. Methods A sample of 712 schizophrenia proband families (696 patients and 766 siblings) and 427 healthy control families (517 subjects) participated in this study. Family history of psychiatric disorder was determined while excluding the data of the participating schizophrenia patient. A dichotomous division was made between families with no first- or second degree relative with psychiatric disorder and families with one or more affected relatives. Total intelligence scores were estimated by admission of the short form of the Wechsler Adult Intelligence Scale III. Results A significant interaction was found between family history of psychiatric disorder and clinical status (F(2,1086.87)= 4.17; p=.016). Patients with a positive family history of psychiatric disorder obtained higher intelligence scores compared to patients with no family history (mean IQ scores are 95.52 and 92.72) with an opposite effect in controls (mean IQ scores are 108.71 and 111.19). No significant difference was found between siblings of schizophrenia patients with or without a positive family history (mean IQ scores are 102.98 and 103.24). Conclusion In patients with schizophrenia, a negative family history of psychiatric disorder was associated with relatively low IQ suggesting that the etiology in these patients may involve environmental or genetic factors which are unique to the patient and are not observed in other relatives. Possible factors include severe environmental

    To compare nasalance scores obtained with the Nasometer, the NasalView, and the OroNasal System; evaluate test-retest reliability of the three systems; and explore whether three common text passages used for nasalance analysis could be shortened to a sentence each. Seventy-six adults with normal speech and hearing (mean age 26.5 years). Subjects read the complete Zoo Passage, Rainbow Passage, and Nasal Sentences. Mean nasalance magnitudes and mean nasalance distances were obtained with the three devices. The Nasometer had the lowest nasalance scores for the nonnasal Zoo Passage. The NasalView had the highest nasalance scores for the phonetically balanced Rainbow Passage. The OroNasal System had the lowest nasalance scores for the Nasal Sentences. The nasalance distance was largest for the Nasometer and smallest for the OroNasal System. Over 90% of the recordings were within 4% to 6% nasalance for most materials recorded with the Nasometer and the NasalView and within 7% to 9% for materials recorded with the OroNasal System. There were significant differences between the complete Zoo Passage and the Nasal Sentences and the individual sentences from these passages for the Nasometer and the OroNasal System. The three systems measure nasalance in different ways and provide nasalance scores that are not interchangeable. Test-retest variability for the Nasometer and the NasalView may be higher than previously reported. Individual sentences from the Zoo Passage and the Nasal Sentences do not provide nasalance scores that are equivalent to the complete passages.

    The Korean translated Appraisal of Guidelines for Research and Evaluation II (Korean AGREE II) instrument was distributed into Korean medical societies in 2011. However, inter-rater disagreement issues still exist. The Korean AGREE II scoring guide was therefore developed to reduce inter-rater differences. This study examines the effects of the Korean AGREE II scoring guide to reduce inter-rater differences. Appraisers were randomly assigned to two groups (Scoring Guide group and Non-Scoring Guide group). The Korean AGREE II instrument was provided to both groups. However, the scoring guide was offered to Scoring Guide group only. Total 14 appraisers were participated and each guideline was assessed by 8 appraisers. To evaluate the reliability of the Korean AGREE II scoring guide, correlation of scores among appraisers and domain-specific intra-class correlation (ICC) were compared. Most scores of two groups were comparable. Scoring Guide group showed higher reliability at all guidelines. They showed higher correlation among appraisers and higher ICC values at almost all domains. The scoring guide reduces the inter-rater disagreement and improves the overall reliability of the Korean-AGREE II instrument.

    Neurodegeneration in Alzheimer disease (AD) begins decades before dementia and patients with mild cognitive impairment (MCI) already demonstrate significant lesion loads. Lack of information about the early pathophysiology in AD complicates the search for therapeutic strategies.Subjective cognitive impairment is the description given to subjects who have memory-related complaints without pathological results on neuropsychological tests. There is no consensus regarding this heterogeneous syndrome, but at least some of these patients may represent the earliest stage in AD. We reviewed available literature in order to summarise current knowledge on subjective cognitive impairment. Although they may not present detectable signs of disease, SCI patients as a group score lower on neuropsychological tests than the general population does, and they also have a higher incidence of future cognitive decline. Depression and psychiatric co-morbidity play a role but cannot account for all cognitive complaints. Magnetic resonance imaging studies in these patients reveal a pattern of hippocampal atrophy similar to that of amnestic mild cognitive impairment and functional MRI shows increased activation during cognitive tasks which might indicate compensation for loss of function. Prevalence of an AD-like pattern of beta-amyloid (Aβ42) and tau proteins in cerebrospinal fluid is higher in SCI patients than in the general population. Memory complaints are relevant symptoms and may predict AD. Interpatient variability and methodological differences between clinical studies make it difficult to assign a definition to this syndrome. In the future, having a standard definition and longitudinal studies with sufficient follow-up times and an emphasis on quantifiable variables may clarify aspects of early AD.

    High levels of anhedonia have been found in patients with schizophrenia; specifically they report higher levels of social anhedonia rather than physical anhedonia, and further, in the anticipatory rather than consummatory facets of pleasure. Nonetheless, contrasting results emerged regarding the underlying mechanisms of this deficit. Basic Symptoms (BS) disturb subjective experiences present for most of the illness' course; this impacts patients' daily lives leading to a loss of the ability to organize the experience of the self and the world in a fluid and automatic way. Considering the role played by negative emotions in the subjective evaluation of anhedonia, the aim of the study is to clarify the role of BS in the assessment of anhedonia in a sample of patients with schizophrenia (n=53) compared with healthy controls (n=46). Participants completed a self-administered trait questionnaire evaluating social anhedonia (Revised-Social Anhedonia Scale), physical anhedonia (Physical Anhedonia Scale), and the consummatory and anticipatory pleasure experiences (Temporal Experience of Pleasure Scale). BS were evaluated with the Frankfurter Beschwerde-Frageboden (FBF) whereas psychopathology was assessed with the Positive and Negative Syndromes Scale. Patients scored higher than healthy controls in social, physical and anticipatory anhedonia, but not in consummatory anhedonia and these relationships were mediated by the FBF. Basic Symptoms of Memory, Overstimulation and Lack of Automatism were related to some facets of anhedonia, independently from depressive symptoms. We hypothesize that a subjective cognitive deficit and a reduced ability in information processing, could prevent patients from retaining a positive experience from past pleasant activities. Therefore the lack of pleasure would be, at least in part, related to an avoidance of potentially stressful new scenarios. Copyright © 2015 Elsevier Inc. All rights reserved.

    Honorary Editor The standard of educational achievement in England and Wales is frequently criticized, and it seems to be an axiom of government that schools and teachers need to be shaken up, kept on a tight rein, copiously inspected, shamed and blamed as required: in general, subjected to the good old approach of: ' Find out what Johnny is doing and tell him to stop.' About the only exception to this somewhat severe attitude is at A-level, where the standard is simply golden. Often, comparisons are made between the performance of, say, English children and that of their coevals in other countries, with different customs, systems, aims and languages. But there has been a recent comparison of standards at A-level with a non-A-level system of pre-university education, in an English-speaking country that both sends students to English universities and accepts theirs into its own, and is, indeed, represented in the UK government at well above the level expected from its ethnical weighting in the population. This semi-foreign country is Scotland. The conclusions of the study are interesting. Scotland has had its own educational system, with `traditional breadth', and managed to escape much of the centralized authoritarianism that we have been through south of the border. It is interesting to note that, while for the past dozen years or so the trend in A-level Physics entries has been downwards, there has been an increase in the take-up of Scottish `Highers'. Highers is a one-year course. Is its popularity due to its being easier than A-level? Scottish students keen enough to do more can move on to the Certificate of Sixth Year Studies, and will shortly be able to upgrade a Higher Level into an Advanced Higher Level. A comparability study [ Comparability Study of Scottish Qualifications and GCE Advanced Levels: Report on Physics January 1998 (free from SQA)] was carried out by the Scottish Qualifications Authority (SQA) with the aim (amongst others) of helping

    The tested hypothesis was following: the High Activity Arthroplasty Score has a significant lower ceiling effect than American Knee Society Score and Oxford Knee Score after total knee arthroplasty. One hundred patients operated on for total knee arthroplasty with more than one-year follow-up have been included. The ceiling effect was 53% for the American Knee Society Score, 33% for the Oxford Knee Score, and 0% for the High Activity Arthroplasty Score. High Activity Arthroplasty Score had a significantly lower ceiling effect than American Knee Society Score and Oxford Knee Score. High Activity Arthroplasty Score has the potential to detect more subtle differences in level of function than standard scoring systems among a non-selected total knee arthroplasty population. © 2014.

    One important aspect of subjective judgments about one's well-being (i.e., subjective well-being: life satisfaction, positive affect, and negative affect) is that cultural features, such as, nationality seem to shape cognitive judgments about the "the ideal life." In this comparative study we examined differences in subjective well-being and psychological well-being between Italian and Swedish adolescents and tested if the relationship between the three constructs of subjective well-being (i.e., satisfaction with life, positive affect, and negative affect) and psychological well-being was moderated by the adolescents' nationality. Italian (n = 255) and Swedish (n = 277) adolescents answered to the Satisfaction with Life Scale, the Positive Affect Negative Affect Schedule, and Ryff's Scales of Psychological Well-Being. Differences between samples were tested using a Multiple Analysis of Variance. We also conducted a multiple group analysis (Italy and Sweden) using Structural Equation Modelling to investigate the relationship between all three subjective well-being constructs and psychological well-being. Italian adolescents scored significantly higher in satisfaction with life than Swedish adolescents. Additionally, across countries, girls scored significantly higher in negative affect than boys. In both countries, all three constructs of subjective well-being were significantly associated to adolescents' psychological well-being. Nevertheless, while the effect of the relationship between affect and psychological well-being was almost the same across countries, life satisfaction was more strongly related to psychological well-being among Swedish adolescents. The present study shows that there are larger variations between these two cultures in the cognitive construct of subjective well-being than in the affective construct. Accordingly, associations between the cognitive component, not the affective component, of subjective well-being and psychological well
