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

Until recently, large-scale, cost-effective net-zero energy buildings (NZEBs) were thought to lie decades in the future. However, ongoing work at the National Renewable Energy Laboratory (NREL) indicates that NZEB status is both achievable and repeatable today. This paper presents a definition framework for classifying NZEBs and a real-life example that demonstrates how a large-scale office building can cost-effectively achieve net-zero energy. The vision of NZEBs is compelling. In theory, these highly energy-efficient buildings will produce, during a typical year, enough renewable energy to offset the energy they consume from the grid. The NREL NZEB definition framework classifies NZEBs according tomore » the criteria being used to judge net-zero status and the way renewable energy is supplied to achieve that status. We use the new U.S. Department of Energy/NREL 220,000-ft{sub 2} Research Support Facilities (RSF) building to illustrate why a clear picture of NZEB definitions is important and how the framework provides a methodology for creating a cost-effective NZEB. The RSF, scheduled to open in June 2010, includes contractual commitments to deliver a Leadership in Energy Efficiency and Design (LEED) Platinum Rating, an energy use intensity of 25 kBtu/ft{sub 2} (half that of a typical LEED Platinum office building), and net-zero energy status. We will discuss the analysis method and cost tradeoffs that were performed throughout the design and build phases to meet these commitments and maintain construction costs at $259/ft{sub 2}. We will discuss ways to achieve large-scale, replicable NZEB performance. Many passive and renewable energy strategies are utilized, including full daylighting, high-performance lighting, natural ventilation through operable windows, thermal mass, transpired solar collectors, radiant heating and cooling, and workstation configurations allow for maximum daylighting.« less

Data on disease burden of multiple sclerosis from Eastern-Central Europe are very limited. Our aim was to explore the quality of life, resource utilisation and costs of ambulating patients with multiple sclerosis in Hungary. Cross-sectional questionnaire survey was performed in two outpatient neurology centres in 2009. Clinical history, health care utilisation in the past 12 months were surveyed, the Expanded Disability Status Scale and the EQ-5D questionnaires were applied. Cost calculation was conducted from the societal perspective. Sixty-eight patients (female 70.6%) aged 38.0 (SD 9.1) with disease duration of 7.8 (SD 6.7) years were involved. Fifty-five (80.9%) had relapsing-remitting form and 52 (76.5%) were taking immunomodulatory drug. The average scores were: Expanded Disability Status Scale 1.9 (SD 1.7), EQ-5D 0.67 (SD 0.28). Mean total cost amounted to 10 902 Euros/patient/year (direct medical 67%, direct nonmedical 13%, indirect costs 20%). Drugs, disability pension and informal care were the highest cost items. Costs of mild (Expanded Disability Status Scale 0-3.5) and moderate (Expanded Disability Status Scale 4.0-6.5) disease were 9 218 and 17 634 Euros/patient/year respectively (p<0.01), that is lower than results from Western European countries. Our study provides current inputs for policy making and contributes to understanding variation of cost-of-illness of multiple sclerosis in Europe.

Cancer disease is usually associated with impaired nutritional status, which is one of the factors contributing to deterioration of the results of surgery, chemotherapy or radiotherapy. The aim of the study was to determine whether nutritional support with high protein (ONS) in adult oncologic patients in the first step of cancer cachexia-asymptomatic precachexia, has an influence on the toxicity of systemic therapy. However, secondary endpoints were established: to determine whether high protein ONS influences the nutritional status, the quality of life, and the performance status. A total of 114 persons aged 40-84 years old with colorectal cancer were examined. Based on the randomization, 47 patients were qualified to the interventional group (ONS group) and 48 to Control group. To evaluate the nutritional status NRS-2002 (Nutritional Risk Screening), SGA (Subjective Global Assessment), SCRINIO (SCReenIng the Nutritional status In Oncology) Working Group classification, VAS (Visual Analog Scale) for appetite was used. FAACT (Functional Assessment of Anorexia/Cachexia Therapy) questionnaire was used for assessment of the quality of life. The health status of patients was evaluated based on the Karnofsky Performance Scale. Anthropometric measurements were done. Severe complications of chemotherapy, which caused the end of treatment, a slight complication of the gastrointestinal tract such as diarrhea grade 2 according to ECOG (Eastern Cooperative Oncology Group) score regardless of the studied group, were observed. There were no statistical differences in the number and severity of the observed complications, i.e., neutropenia, leucopenia, thrombocytopenia, anemia, abdominal pain, nausea and vomiting, and diarrhea. During the follow-up the significant changes of SGA, VAS, albumin and prealbumin were observed between groups. In the ONS group an improvement in nutritional status was noticed (increased appetite VAS, p = 0.05; increased points in SGA, p = 0.015, and increased levels of albumin and prealbumin, p = 0.05). In Control group nutritional status was stable during observation. The performance status and quality of life were stable in both groups. No statistical differences between groups (ONS vs. Control) in the numbers for disqualification, resignation, delay in treatment, or dose reduction were observed. Results of the study did not indicate that nutritional support in precachectic oncologic patients influenced the toxicity of systemic therapy. High protein nutritional support improved nutritional status assessed by SGA, VAS for appetite, albumin, and prealbumin. The performance status and quality of life were stable throughout the observation and were not changed under the supplementation.

Decision-making is reported to be impaired in anorexia nervosa (AN) and bulimia nervosa (BN), but the influence of mood status, pathophysiological eating, and weight concerns on the performance of decision-making ability between AN and BN is still unclear. The aims of this study were to investigate differential impairments in the decision-making process between AN, BN, and healthy controls (HC), and secondly, to explore the role of mood status, such as anxiety, depression, pathological eating, and weight concerns, in decision-making ability. Patients suffering from AN (n = 22), BN (n = 36) and age-matched HC (n = 51) were assessed for their decision-making abilities using the Iowa Gambling Task (IGT). Self-reported questionnaires including the Eating Disorder Examination Questionnaire (EDE-Q), the Bulimia Investigatory Test, Edinburgh (BITE), the Eating Disorders Inventory, the Maudsley Obsessive-Compulsive Inventory measuring obsessive-compulsive traits, the Hospital Anxiety and Depression Scale, and the Toronto Alexithymia Scale were used to assess pathological eating concerns and attitude to feelings. Significant differences in IGT performance were observed between BN and HC. Significant negative correlation was found between IGT performance and the BITE symptom subscale in AN. In BN, there was a negative correlation between the EDE-Q weight concerns subscale and IGT performance. It was also found that increased anxiety, depression, and eating/weight concerns predicted poorer decision-making. Different patterns of association between pathological eating concerns/behaviors and performances in decision-making ability were found between AN, BN, and HC. Anxiety, depressive mood status, and eating/weight concerns were related to decision-making ability.

A clinimetric approach to assessing quality of life in epilepsy.

PubMed

Cramer, J A

1993-01-01

Clinimetrics is a concept involving the use of rating scales for clinical phenomena ranging from physical examinations to functional performance. Clinimetric or rating scales can be used for defining patient status and changes that occur during long-term observation. The scores derived from such scales can be used as guidelines for intervention, treatment, or prediction of outcome. In epilepsy, clinimetric scales have been developed for assessing seizure frequency, seizure severity, adverse effects related to antiepileptic drugs (AEDs), and quality of life after surgery for epilepsy. The VA Epilepsy Cooperative Study seizure rating scale combines frequency and severity in a weighted scoring system for simple and complex partial and generalized tonic-clonic seizures, summing all items in a total seizure score. Similarly, the rating scales for systemic toxicity and neurotoxicity use scores weighted for severity for assessing specific adverse effects typically related to AEDs. A composite score, obtained by adding the scores for seizures, systemic toxicity, and neurotoxicity, represents the overall status of the patient at a given time. The Chalfont Seizure Severity Scale also applies scores relative to the impact of a given item on the patient, without factoring in seizure frequency. The Liverpool Seizure Severity Scale is a patient questionnaire covering perceived seizure severity and the impact of ictal and postictal events. The UCLA Epilepsy Surgery Inventory (ESI-55) assesses quality of life for patients who have undergone surgery for epilepsy using generic health status instruments with additional epilepsy-specific items.(ABSTRACT TRUNCATED AT 250 WORDS)

Biodiversity Mapping via Natura 2000 Conservation Status and Ebv Assessment Using Airborne Laser Scanning in Alkali Grasslands

Biodiversity is an ecological concept, which essentially involves a complex sum of several indicators. One widely accepted such set of indicators is prescribed for habitat conservation status assessment within Natura 2000, a continental-scale conservation programme of the European Union. Essential Biodiversity Variables are a set of indicators designed to be relevant for biodiversity and suitable for global-scale operational monitoring. Here we revisit a study of Natura 2000 conservation status mapping via airbone LIDAR that develops individual remote sensing-derived proxies for every parameter required by the Natura 2000 manual, from the perspective of developing regional-scale Essential Biodiversity Variables. Based on leaf-on and leaf-off point clouds (10 pt/m2) collected in an alkali grassland area, a set of data products were calculated at 0.5 ×0.5 m resolution. These represent various aspects of radiometric and geometric texture. A Random Forest machine learning classifier was developed to create fuzzy vegetation maps of classes of interest based on these data products. In the next step, either classification results or LIDAR data products were selected as proxies for individual Natura 2000 conservation status variables, and fine-tuned based on field references. These proxies showed adequate performance and were summarized to deliver Natura 2000 conservation status with 80% overall accuracy compared to field references. This study draws attention to the potential of LIDAR for regional-scale Essential Biodiversity variables, and also holds implications for global-scale mapping. These are (i) the use of sensor data products together with habitat-level classification, (ii) the utility of seasonal data, including for non-seasonal variables such as grassland canopy structure, and (iii) the potential of fuzzy mapping-derived class probabilities as proxies for species presence and absence.

Our research is motivated by 2 methodological problems in assessing diagnostic accuracy of traditional Chinese medicine (TCM) doctors in detecting a particular symptom whose true status has an ordinal scale and is unknown—imperfect gold standard bias and ordinal scale symptom status. In this paper, we proposed a nonparametric maximum likelihood method for estimating and comparing the accuracy of different doctors in detecting a particular symptom without a gold standard when the true symptom status had an ordered multiple class. In addition, we extended the concept of the area under the receiver operating characteristic curve to a hyper-dimensional overall accuracy for diagnostic accuracy and alternative graphs for displaying a visual result. The simulation studies showed that the proposed method had good performance in terms of bias and mean squared error. Finally, we applied our method to our motivating example on assessing the diagnostic abilities of 5 TCM doctors in detecting symptoms related to Chills disease. PMID:21209155

Recently, there are few studies reporting on depressive status and obstructive sleep apnoea (OSA) in China. A large-sample survey was to be performed to explore the prevalence of depressive status and related factors in Chinese patients with OSA. From among a randomly-selected group of OSA patients, 1,327 met inclusion criteria. After screening with the Symptom Checklist 90 (SCL-90) and Self-Rating Depression Scale (SDS), patients were assigned to OSA without depressive status (control group, n = 698) and OSA with depressive status (n = 629) groups. Using chi-squared testing, the correlation analyses between the depressive status and OSA patient demographic and clinical variables were tested. Then depression-related risk factors in OSA patients were analysed using stepwise linear regression analysis. The effects of family and social factors on depressive status in OSA patients were investigated using Mann-Whitney U (one of nonparametric test). The prevalence of depressive status was 47.4% in OSA patients. Depressive status was significantly associated with female gender, single status, Family Burden Scale of Disease (FBS), Family APGAR Index (APGAR), apnoea-hypopnea index (AHI), and Perceived Social Support Scale (PSSS). Stepwise linear regression analysis further indicated that single status, hypoxemia, APGAR, AHI, PSSS, AHI, and FBS were all risk factors for depressive status in OSA patients. The total of the FBS score and three of its sub-factors scores (family daily activities, family relationships and mental health of family members) were higher, and the total of the APGAR score and two of its sub-factors scores (adaptability and affection) were lower in OSA with depressive status compared with the control group. Besides, the total score for the PSSS and scores for its two sub-factors (family support and social support) were all lower in OSA patients with depressive status than those of the control group. Depressive status has high comorbid rate in Chinese OSA patients and is significantly associated with single status, apnoea-hypopnea index, hypoxemia, family and social supports.

2015-11-01

Dropout of infants in looking time studies sometimes occurs at high rates, raising concerns that the representativeness of the final sample might be reduced in comparison to the originally obtained sample. The current study investigated which infant characteristics play a role in dropout. Infants were presented with a preferential looking task at 6 and 9 months of age. At 9 months of age, an additional habituation task and a subsequent novelty preference task were conducted. In addition, temperament was assessed via the Infant Behavior Questionnaire - Revised (IBQ-R, Gartstein & Rothbart, 2003), and cognitive developmental status was assessed via the Cognitive Scale of the Bayley Scale of Infant and Toddler Development (BSID-III, Bayley, 2006). Dropout was positively related to the IBQ-R temperament scales Distress to Limitations and Approach, and negatively related to the scales Falling Reactivity and Cuddliness. The representativeness of the final sample regarding situation-specific temperament dimensions is affected by dropout. Dropout was not related to cognitive developmental status as measured via the BSID-III, habituation speed and novelty preference. Dropout at 6 months of age was associated with dropout at 9 months of age. We concluded that in looking time studies, the representativeness of the final sample regarding performance-relevant temperament dimensions or cognitive developmental status is not affected by dropout.

Assessing water status and optimizing irrigation is of utmost importance in most winegrowing countries, as the grapevine vegetative growth, yield, and grape quality can be impaired under certain water stress situations. Conventional plant-based methods for water status monitoring are either destructive or time and labor demanding, therefore unsuited to detect the spatial variation of moisten content within a vineyard plot. In this context, this work aims at the development and comprehensive validation of a novel, non-destructive methodology to assess the vineyard water status distribution using on-the-go, contactless, near infrared (NIR) spectroscopy. Likewise, plant water status prediction models were built and intensely validated using the stem water potential (ψs) as gold standard. Predictive models were developed making use of a vast number of measurements, acquired on 15 dates with diverse environmental conditions, at two different spatial scales, on both sides of vertical shoot positioned canopies, over two consecutive seasons. Different cross-validation strategies were also tested and compared. Predictive models built from east-acquired spectra yielded the best performance indicators in both seasons, with determination coefficient of prediction (RP2) ranging from 0.68 to 0.85, and sensitivity (expressed as prediction root mean square error) between 0.131 and 0.190 MPa, regardless the spatial scale. These predictive models were implemented to map the spatial variability of the vineyard water status at two different dates, and provided useful, practical information to help delineating specific irrigation schedules. The performance and the large amount of data that this on-the-go spectral solution provides, facilitates the exploitation of this non-destructive technology to monitor and map the vineyard water status variability with high spatial and temporal resolution, in the context of precision and sustainable viticulture.

Functional outcomes in individuals with schizophrenia suggest recovery of cognitive, everyday, and social functioning. Specifically improvement of work status is considered to be most important for their independent living and self-efficacy. The main purposes of the present study were 1) to identify which outcome factors predict occupational functioning, quantified as work hours, and 2) to provide cut-offs on the scales for those factors to attain better work status. Forty-five Japanese patients with schizophrenia and 111 healthy controls entered the study. Cognition, capacity for everyday activities, and social functioning were assessed by the Japanese versions of the MATRICS Cognitive Consensus Battery (MCCB), the UCSD Performance-based Skills Assessment-Brief (UPSA-B), and the Social Functioning Scale Individuals' version modified for the MATRICS-PASS (Modified SFS for PASS), respectively. Potential factors for work outcome were estimated by multiple linear regression analyses (predicting work hours directly) and a multiple logistic regression analyses (predicting dichotomized work status based on work hours). ROC curve analyses were performed to determine cut-off points for differentiating between the better- and poor work status. The results showed that a cognitive component, comprising visual/verbal learning and emotional management, and a social functioning component, comprising independent living and vocational functioning, were potential factors for predicting work hours/status. Cut-off points obtained in ROC analyses indicated that 60-70% achievements on the measures of those factors were expected to maintain the better work status. Our findings suggest that improvement on specific aspects of cognitive and social functioning are important for work outcome in patients with schizophrenia.

To describe the results of a multicenter study that validated two new patient-reported measures of neurologic impairment and disability for use in MS clinical research. Self-reported data can provide a cost-effective means to assess patient functioning, and can be useful for screening patients who require additional evaluation. Thirteen MS centers from the United States and Canada implemented a cross-sectional validation study of two new measures of neurologic function. The Symptom Inventory is a measure of neurologic impairment with six subscales designed to correlate with localization of brain lesion. The Performance Scales measure disability in eight domains of function: mobility, hand function, vision, fatigue, cognition, bladder/bowel, sensory, and spasticity. Measures given for comparison included a neurologic examination (Expanded Disability Status Scale, Ambulation Index, Disease Steps) as well as the patient-reported Health Status Questionnaire and the Quality of Well-being Index. Participants included 274 MS patients and 296 healthy control subjects who were matched to patients on age, gender, and education. Both the Symptom Inventory and the Performance Scales showed high test-retest and internal consistency reliability. Correlational analyses supported the construct validity of both measures. Discriminant function analysis reduced the Symptom Inventory to 29 items without sacrificing reliability and increased its discriminant validity. The Performance Scales explained more variance in clinical outcomes and global quality of life than the Symptom Inventory, and there was some evidence that the two measures complemented each other in predicting Quality of Well-being Index scores. The Symptom Inventory and the Performance Scales are reliable and valid measures.

Analyses were conducted to examine ion thruster scaling relationships in detail to determine performance limits, and lifetime expectations for thruster input power levels below 0.5 kW. This was motivated by mission analyses indicating the potential advantages of high performance, high specific impulse systems for small spacecraft. The design and development status of a 0.1-0.3 kW prototype small thruster and its components are discussed. Performance goals include thruster efficiencies on the order of 40% to 54% over a specific impulse range of 2000 to 3000 seconds, with a lifetime in excess of 8000 hours at full power. Thruster technologies required to achieve the performance and lifetime targets are identified.

There is a paucity of normative studies outside of North America and on elderly populations with very low education level. In the present study we examined the performance of poorly educated elderly on the Repeatable Battery Assessment of Neuropsychological Status (RBANS) with 352 cognitively normal elderly Chinese persons living in the community in Singapore who were enrolled in the Singapore Longitudinal Ageing Study (SLAS). Those with no formal education performed significantly less well than those with some years of formal education across four of five RBANS indices as well as the Total Scale score. Age- and education-adjusted normative data for the RBANS were established for the sample. The means and standard deviations of each of 12 subtests raw scores, five Index scores and the Total Scale score were calculated and stratified by age and education. Data from the present study should considerably advance the clinical utility of the RBANS in Chinese geriatric evaluations in Singapore, and can serve as a reference source for poorly educated elderly Chinese from around the region and beyond.

Few studies have evaluated magnetic resonance imaging (MRI) visual scales in Parkinson's disease-Mild Cognitive Impairment (PD-MCI). We selected 79 PD patients and 92 controls (CO) to perform neurologic and neuropsychological evaluation. Brain MRI was performed to evaluate the following scales: Global Cortical Atrophy (GCA), Fazekas, and medial temporal atrophy (MTA). The analysis revealed that both PD groups (amnestic and nonamnestic) showed worse performance on several tests when compared to CO. Memory, executive function, and attention impairment were more severe in amnestic PD-MCI group. Overall analysis of frequency of MRI visual scales by MCI subtype did not reveal any statistically significant result. Statistically significant inverse correlation was observed between GCA scale and Mini-Mental Status Examination (MMSE), Montreal Cognitive Assessment (MoCA), semantic verbal fluency, Stroop test, figure memory test, trail making test (TMT) B, and Rey Auditory Verbal Learning Test (RAVLT). The MTA scale correlated with Stroop test and Fazekas scale with figure memory test, digit span, and Stroop test according to the subgroup evaluated. Visual scales by MRI in MCI should be evaluated by cognitive domain and might be more useful in more severely impaired MCI or dementia patients.

To examine the relationship between the two disease-specific measures currently in use to assess swallowing outcomes following treatment in patients with head and neck cancer: the Performance Status Scale (PSS) and MD Anderson Dysphagia Inventory (MDADI). A prospective cohort study. Four head and neck cancer multidisciplinary clinics in the North of England Cancer Network. 114 patients with cancers of the upper aerodigestive tract. Measures of swallowing function administered prospectively across 4 timepoints Spearman's correlation coefficients were used to measure the relationship between the two scales. There was statistically significant correlation between the two tools at pre-treatment (rs = 0.428, P < 0.000), 3 months post-treatment (rs = 0.454, P < 0.002), 6 months post-treatment (rs = 0.551, P < 0.000) and 12 months post-treatment (rs = 0.680, P < 0.000). This is the first prospective study comparing the MDADI and PSS questionnaires at multiple time points. Our study shows that these different instruments have a good relationship in measuring swallowing function in patients with head and neck cancer in short and medium term after treatment. © 2015 John Wiley & Sons Ltd.

The impact of socioeconomic status on health has been extensively studied and studies have shown that low socio-economic status is related to lower values of various health and quality-of-health measures. The aim of this study was to assess the influence of demographic and socio-economic factors on health- related quality of life (HRQoL). A cross-sectional study was carried out in 2003 using a representative sample of a Greek general population (n = 1007, 18+ years old), living in Athens area. Multivariate stepwise linear regression analyses were performed to investigate the influence of socio-demographic and economic variables on HRQoL, measured by eight scales of the SF-36. Interaction effects between socioeconomic status (SES) and demographic variables were also performed. Females and elderly people were associated with impaired HRQoL in all SF-36 scales. Disadvantaged SES i. e. primary education and low total household income was related to important decline in HRQoL and a similar relation was identified among men and women. Only the interaction effects between age and SES was statistically significant for some SF-36 scales. Multiple regression analyses produced models explaining significant portions of the variance in SF-36 scales, especially physical functioning. The analysis presented here gives evidence of a relationship existing between SES and HRQoL similar to what has been found elsewhere. In order to protect people from the damaging effects of poverty in health it is important to formulate health promotion educational programs or to direct policies to empower the disposable income etc. Helping people in disadvantaged SES to achieve the good health that people in more advantaged SES attained would help to prevent the widening of health inequalities.

The purpose of this study was to evaluate longitudinally, using the Iowa Gambling Task (IGT), the dynamics of decision-making capacity at a two-year interval (median: 2.1 years) in a group of patients with multiple sclerosis (MS) (n = 70) and minor neurological disability [Expanded Disability Status Scale (EDSS) < or = 2.5 at baseline]. Cognition (memory, executive functions, attention), behavior, handicap, and perceived health status were also investigated. Standardized change scores [(score at retest-score at baseline)/standard deviation of baseline score] were computed. Results showed that IGT performances decreased from baseline to retest (from 0.3, SD = 0.4 to 0.1, SD = 0.3, p = .005). MS patients who worsened in the IGT were more likely to show a decreased perceived health status and emotional well-being (SEP-59; p = .05 for both). Relapsing rate, disability progression, cognitive, and behavioral changes were not associated with decreased IGT performances. In conclusion, decline in decision making can appear as an isolated deficit in MS.

The Berg Balance Scale (BBS), Balance Evaluation Systems Test (BESTest), Mini-BESTest, and Brief-BESTest are useful in the assessment of balance. Their psychometric properties, however, have not been tested in patients with chronic obstructive pulmonary disease (COPD). This study aimed to compare the validity, reliability, and ability to identify fall status of the BBS, BESTest, Mini-BESTest, and the Brief-BESTest in patients with COPD. A cross-sectional study was conducted. Forty-six patients (24 men, 22 women; mean age=75.9 years, SD=7.1) were included. Participants were asked to report their falls during the previous 12 months and to fill in the Activity-specific Balance Confidence (ABC) Scale. The BBS and the BESTest were administered. Mini-BESTest and Brief-BESTest scores were computed based on the participants' BESTest performance. Validity was assessed by correlating balance tests with each other and with the ABC Scale. Interrater reliability (2 raters), intrarater reliability (48-72 hours), and minimal detectable changes (MDCs) were established. Receiver operating characteristics assessed the ability of each balance test to differentiate between participants with and without a history of falls. Balance test scores were significantly correlated with each other (Spearman correlation rho=.73-.90) and with the ABC Scale (rho=.53-.75). Balance tests presented high interrater reliability (intraclass correlation coefficient [ICC]=.85-.97) and intrarater reliability (ICC=.52-.88) and acceptable MDCs (MDC=3.3-6.3 points). Although all balance tests were able to identify fall status (area under the curve=0.74-0.84), the BBS (sensitivity=73%, specificity=77%) and the Brief-BESTest (sensitivity=81%, specificity=73%) had the higher ability to identify fall status. Findings are generalizable mainly to older patients with moderate COPD. The 4 balance tests are valid, reliable, and valuable in identifying fall status in patients with COPD. The Brief-BESTest presented slightly higher interrater reliability and ability to differentiate participants' fall status. © 2016 American Physical Therapy Association.

Introduction: cognitive, emotional and psychopathological changes play a significant role in the clinical picture of multiple sclerosis and influence the effectiveness of drug therapy, working capacity, quality of life, and the process of rehabilitation of patients with multiple sclerosis. The aim: investigate the changes in cognitive function in patients with multiple sclerosis, such as information processing speed and working memory of patients before and after treatment with immunomodulating drug. Materials and methods:33 patients examined reliably diagnosed with multiple sclerosis who were treated with preventive examinations and treatment from 2012 to 2016. For all patients with multiple sclerosis had clinical-neurological examination (neurological status using the EDSS scale) and the cognitive status was evaluated using the PASAT auditory test. Patient screening was performed before, during and after the therapy. Statistical analysis of the results was performed in the system Statistica 8.0. We used Student's t-test (t), Mann-Whitney test (Z). Person evaluated the correlation coefficients and Spearman (r, R), Wilcoxon criterion (T), Chi-square (X²). Results: The age of patients with multiple sclerosis affects the growth and EDSS scale score decrease PASAT to treatment. Duration of illness affects the EDSS scale score and performance PASAT. Indicators PASAT not significantly decreased throughout the treatment. Conclusions: glatiramer acetate has a positive effect on cognitive function, information processing speed and working memory patients with multiple sclerosis, which is one of the important components of the therapeutic effect of this drug.

Stroke-induced focal brain lesions often exert remote effects via residual neural network activity. Electroencephalographic (EEG) techniques can assess neural network modifications after brain damage. Recently, EEG phase synchrony analyses have shown associations between the level of large-scale phase synchrony of brain activity and clinical symptoms; however, few reports have assessed such associations in stroke patients. The aim of this study was to investigate the clinical relevance of hemispheric phase synchrony in stroke patients by calculating its correlation with clinical status. This cross-sectional study included 19 patients with post-acute ischemic stroke admitted for inpatient rehabilitation. Interhemispheric phase synchrony indices (IH-PSIs) were computed in 2 frequency bands (alpha [α], and beta [β]), and associations between indices and scores of the Functional Independence Measure (FIM), the National Institutes of Health Stroke Scale (NIHSS), and the Fugl-Meyer Motor Assessment (FMA) were analyzed. For further assessments of IH-PSIs, ipsilesional intrahemispheric PSIs (IntraH-PSIs) as well as IH- and IntraH-phase lag indices (PLIs) were also evaluated. IH-PSIs correlated significantly with FIM scores and NIHSS scores. In contrast, IH-PSIs did not correlate with FMA scores. IntraH-PSIs correlate with FIM scores after removal of the outlier. The results of analysis with PLIs were consistent with IH-PSIs. The PSIs correlated with performance on the activities of daily living scale but not with scores on a pure motor impairment scale. These results suggest that large-scale phase synchrony represented by IH-PSIs provides a novel surrogate marker for clinical status after stroke.

The purpose of this study was to analyze the relationships between muscular performance consisting of a single repetition on the chair squat exercise (CSQ) and different measures of functional capacity, balance, quality of life and cognitive status in older adults. A total of 40 participants (22 women, 18 men; age = 72.2 ± 4.9 years) joined the investigation. Muscular performance was assessed by measuring movement velocity in the CSQ with no external load using a validated smartphone application ( PowerLift for iOS). Functional capacity, balance, quality of life and cognitive status were evaluated using the hand-grip strength (HGS) test, the Berg-scale, the EuroQol 5D (EQ-5D) and the Mini mental state examination questionnaire (MMSE). Finally, participants were divided into two subgroups ( N = 20) according to their velocity in the CSQ exercise. Positive correlations were obtained between movement velocity in the CSQ and HGS ( r = 0.76, p < 0.001), the Berg-scale ( r = 0.65, p < 0.001), the EQ-5D ( r = 0.34, p = 0.03) and the MMSE ( r = 0.36, p = 0.02). Participants in the fastest subgroup showed very likely higher scores in the Berg-scale (ES = 1.15) and the HGS (ES = 1.79), as well as likely higher scores in the MMSE scale (ES = 0.69). These results could have potential clinical relevance as they support the use of a time-efficient, non-fatiguing test of muscular performance (i.e., the CSQ) to evaluate functional capacity and mental cognition in older adults.

To determine the efficacy of the food supplement OPC Factor to increase energy levels in healthy adults aged 45 to 65. Randomized, placebo-controlled, triple-blind crossover study. Twenty-five (25) healthy adults recruited from the University of Pennsylvania Health System. OPC Factor,trade mark (AlivenLabs, Lebanon, TN) a food supplement that contains oligomeric proanthocyanidins from grape seeds and pine bark along with other nutrient supplements including vitamins and minerals, was in the form of an effervescent powder. The placebo was similar in appearance and taste. Five outcome measurements were performed: (1) Energy subscale scores of the Activation-Deactivation Adjective Check List (AD ACL); (2) One (1) global question of percent energy change (Global Energy Percent Change); (3) One (1) global question of energy change measured on a Likert scale (Global Energy Scale Change); 4. One (1) global question of percent overall status change (Global Overall Status Percent Change); and (5) One (1) global question of overall status change measured on a Likert scale (Global Overall Status Scale Change). There were no carryover/period effects in the groups randomized to Placebo/Active Product sequence versus Active Product/Placebo sequence. Examination of the AD ACL Energy subscale scores for the Active Product versus Placebo comparison revealed no significant difference in the intention-to-treat (IT) analysis and the treatment received (TR) analysis. However, Global Energy Percent Change (p = 0.06) and Global Energy Scale Change (p = 0.09) both closely approached conventional levels of statistical significance for the active product in the IT analysis. Global Energy Percent Change (p = 0.05) and Global Energy Scale Change (p = 0.04) reached statistical significance in the TR analysis. A cumulative percent responders analysis graph indicated greater response rates for the active product. OPC Factor may increase energy levels in healthy adults aged 45-65 years. A larger study is recommended. Clinical Trials.gov identifier: NCT03318019.

2004-01-01

Outcome assessment in patients with rheumatoid arthritis (RA) includes measurement of physical function. We derived a scale to quantify global physical function in RA, using three performance-based rheumatology function tests (RFTs). We measured grip strength, walking velocity, and shirt button speed in consecutive RA patients attending scheduled appointments at six rheumatology clinics, repeating these measurements after a median interval of 1 year. We extracted the underlying latent variable using principal component factor analysis. We used the Bayesian information criterion to assess the global physical function scale's cross-sectional fit to criterion standards. The criteria were joint tenderness, swelling, and deformity, pain, physical disability, current work status, and vital status at 6 years after study enrolment. We computed Guyatt's responsiveness statistic for improvement according to the American College of Rheumatology (ACR) definition. Baseline functional performance data were available for 777 patients, and follow-up data were available for 681. Mean ± standard deviation for each RFT at baseline were: grip strength, 14 ± 10 kg; walking velocity, 194 ± 82 ft/min; and shirt button speed, 7.1 ± 3.8 buttons/min. Grip strength and walking velocity departed significantly from normality. The three RFTs loaded strongly on a single factor that explained ≥70% of their combined variance. We rescaled the factor to vary from 0 to 100. Its mean ± standard deviation was 41 ± 20, with a normal distribution. The new global scale had a stronger fit than the primary RFT to most of the criterion standards. It correlated more strongly with physical disability at follow-up and was more responsive to improvement defined according to the ACR20 and ACR50 definitions. We conclude that a performance-based physical function scale extracted from three RFTs has acceptable distributional and measurement properties and is responsive to clinically meaningful change. It provides a parsimonious scale to measure global physical function in RA. PMID:15225367

Psychosocial correlates of fatigue in multiple sclerosis.

To explore: (1) the interrelation among the neuropsychological, psychological, and psychosocial factors and fatigue as measured by the Multidimensional Assessment of Fatigue scale, and (2) the impact of fatigue on role performance. Clinical interview with neuropsychological testing and cross-sectional study by mail. Multiple sclerosis (MS) clinic registry of a large Boston teaching hospital. 139 MS patients representing a broad range of disability. The Multidimensional Assessment of Fatigue (MAF) scale, the Extended Disability Status Scale, the Sickness Impact Profile, Rao cognitive battery, the Trailmaking Test, depression, anxiety, and social activity limitations subscales from the Arthritis Impact Measurement Scales, and the Ryff Happiness Scale. Stepwise multiple regression analyses revealed that having a low sense of environmental mastery was the best psychosocial predictor of both global fatigue and fatigue-related distress, after adjusting for sociodemographic and medical factors. Further, people who reported being more depressed tended to report more severe fatigue. Neuropsychological performance was not associated with fatigue. Fatigue was found to limit social, work, and overall role performance, but not physical role performance. People who feel that they can choose or create environments suitable to their psychic or physical conditions report less global fatigue and less fatigue-related distress, and fatigue can have an important impact on role performance. The implications of these findings for designing fatigue management interventions are discussed.

Patients with brain metastasis (BM) usually suffer from poor quality of life (QOL), anxiety, depression, and sleep disorders in their reduced lifespan. The aim of this study was to evaluate QOL, anxiety, depression, and sleep characteristics in patients with BM at the beginning and end of whole brain radiation therapy (WBRT) and three months after treatment. Thirty-three patients undergoing WBRT for BM were featured in this study. The authors used the Karnofsky Performance Status (KPS) scale to measure performance status, the Hospital Anxiety and Depression Scale (HADS) to evaluate anxiety and depression, the SF-36® to evaluate health-related QOL, and the Pittsburgh Sleep Quality Index to evaluate sleep disorders at the start of WBRT, the end of WBRT, and three months after WBRT. Statistically significant improvements were noted in KPS scores from baseline evaluation to the end of WBRT and to three months after WBRT. No significant differences were observed in SF-36 and HADS scores between the start and the end of WBRT. Anxiety scores were negatively correlated with survival at the end of WBRT. Overall survival was better in those who reported better sleep. WBRT improves KPS scores and does not worsen sleep quality or mood, even in patients with poor performance status. When changes in mood and sleep quality are observed, survival and QOL may improve in patients with BM; consequently, nurses should be responsive to these changes.

This study is a response to the need for evidence-based measures of spontaneous oral language to assess African American children under the age of 4 years. We determined if pass/fail status on a minimal competence core for morphosyntax (MCC-MS) was more highly related to scores on the Index of Productive Syntax (IPSyn)-the measure of convergent criterion validity-than to scores on 3 measures of divergent validity: number of different words (Watkins, Kelly, Harbers, & Hollis, 1995), Percentage of Consonants Correct-Revised (Shriberg, Austin, Lewis, McSweeney, & Wilson, 1997), and the Leiter International Performance Scale-Revised (Roid & Miller, 1997). Archival language samples for 68 African American 3-year-olds were analyzed to determine MCC-MS pass/fail status and the scores on measures of convergent and divergent validity. Higher IPSyn scores were observed for 60 children who passed the MCC-MS than for 8 children who did not. A significant positive correlation, rpb = .73, between MCC-MS pass/fail status and IPSyn scores was observed. This coefficient was higher than MCC-MS correlations with measures of divergent validity: rpb = .13 (Leiter International Performance Scale-Revised), rpb = .42 (number of different words in 100 utterances), and rpb = .46 (Percentage of Consonants Correct-Revised). The MCC-MS has convergent criterion validity with the IPSyn. Although more research is warranted, both measures can be potentially used in oral language assessments of African American 3-year-olds.

To establish the relationship between socioeconomic inequality and health problems amongst Mexican population reviewing studies with national or regional representation. A literature search was performed at national and international databases using the following keywords: health, disease, mental disorders, nutrition, food, social class, social status, unemployment, employment, occupation, income, wage, poverty and socioeconomic status. Reports of national or regional surveys conducted from the nineties were included. Mostly, diseases events were more common among people from low socioeconomic status: anencephaly, viral infections, anemia, transit accidents by run over, metabolic syndrome, hypertension, affective disorder, anxiety and substances abuse; some malignancies, difficulties to perform activities of daily living, and poor perceived health status. On the opposite, as it goes down in the social scale, are less frequent some protective factors (e.g. fruits or vegetables intake and physical activity) and there is less access to medical aid and preventive interventions (e.g. condom use or diagnosis and treatment for HIV infection, hypertension or obesity). Socioeconomic status affects all living conditions; therefore, its effects are not confined to certain diseases, but a general precarious state of health. The conceptual and public policy implications related with social inequalities in health are discussed.

Production technology for automotive lithium-ion battery (LIB) cells and packs has improved considerably in the past five years. However, the transfer of developments in materials, cell design and processes from lab scale to production scale remains a challenge due to the large number of consecutive process steps and the significant impact of material properties, electrode compositions and cell designs on processes. This requires an in-depth understanding of the individual production processes and their interactions, and pilot-scale investigations into process parameter selection and prototype cell production. Furthermore, emerging process concepts must be developed at lab and pilot scale that reduce production costs and improve cell performance. Here, we present an introductory summary of the state-of-the-art production technologies for automotive LIBs. We then discuss the key relationships between process, quality and performance, as well as explore the impact of materials and processes on scale and cost. Finally, future developments and innovations that aim to overcome the main challenges are presented.

Healthcare4VideoStorm: Making Smart Decisions Based on Storm Metrics.

Storm-based stream processing is widely used for real-time large-scale distributed processing. Knowing the run-time status and ensuring performance is critical to providing expected dependability for some applications, e.g., continuous video processing for security surveillance. The existing scheduling strategies' granularity is too coarse to have good performance, and mainly considers network resources without computing resources while scheduling. In this paper, we propose Healthcare4Storm, a framework that finds Storm insights based on Storm metrics to gain knowledge from the health status of an application, finally ending up with smart scheduling decisions. It takes into account both network and computing resources and conducts scheduling at a fine-grained level using tuples instead of topologies. The comprehensive evaluation shows that the proposed framework has good performance and can improve the dependability of the Storm-based applications.

2018-01-01

The scale at which analyses are performed can have an effect on model results and often one scale does not accurately describe the ecological phenomena of interest (e.g., population trends) for wide-ranging species: yet, most ecological studies are performed at a single, arbitrary scale. To best determine local and regional trends for greater sage-grouse (Centrocercus urophasianus) in Wyoming, USA, we modeled density-independent and -dependent population growth across multiple spatial scales relevant to management and conservation (Core Areas [habitat encompassing approximately 83% of the sage-grouse population on ∼24% of surface area in Wyoming], local Working Groups [7 regional areas for which groups of local experts are tasked with implementing Wyoming's statewide sage-grouse conservation plan at the local level], Core Area status (Core Area vs. Non-Core Area) by Working Groups, and Core Areas by Working Groups). Our goal was to determine the influence of fine-scale population trends (Core Areas) on larger-scale populations (Working Group Areas). We modeled the natural log of change in population size ( peak M lek counts) by time to calculate the finite rate of population growth (λ) for each population of interest from 1993 to 2015. We found that in general when Core Area status (Core Area vs. Non-Core Area) was investigated by Working Group Area, the 2 populations trended similarly and agreed with the overall trend of the Working Group Area. However, at the finer scale where Core Areas were analyzed separately, Core Areas within the same Working Group Area often trended differently and a few large Core Areas could influence the overall Working Group Area trend and mask trends occurring in smaller Core Areas. Relatively close fine-scale populations of sage-grouse can trend differently, indicating that large-scale trends may not accurately depict what is occurring across the landscape (e.g., local effects of gas and oil fields may be masked by increasing larger populations).

Shift work influences health, performance, activity, and social relationships, and it causes impairment in cognitive functions. In this study, we investigated the effects of shift work on participants' cognitive functions in terms of memory, attention, and learning, and we measured the effects on oxidative stress. Additionally, we investigated whether there were significant relationships between cognitive functions and whole blood oxidant/antioxidant status of participants. A total of 90 health care workers participated in the study, of whom 45 subjects were night-shift workers. Neuropsychological tests were administered to the participants to assess cognitive function, and blood samples were taken to detect total antioxidant capacity and total oxidant status at 08:00. Differences in anxiety, depression, and chronotype characteristics between shift work groups were not significant. Shift workers achieved significantly lower scores on verbal memory, attention-concentration, and the digit span forward sub-scales of the Wechsler Memory Scale-Revised (WMS-R), as well as on the immediate memory and total learning sub-scales of the Auditory Verbal Learning Test (AVLT). Oxidative stress parameters were significantly associated with some types of cognitive function, including attention-concentration, recognition, and long-term memory. These findings suggest that night shift work may result in significantly poorer cognitive performance, particularly working memory. © 2013 Elsevier Ireland Ltd. All rights reserved.

Quality of life and positive psychological variables has become a focus of concern in patients with renal carcinoma. However, the integrative effects of positive psychological variables on the illness have seldom been reported. The aims of this study were to evaluate the quality of life and the integrative effects of hope, resilience and optimism on the quality of life among Chinese renal carcinoma patients. A cross-sectional study was conducted at the First Hospital of China Medical University. 284 participants completed questionnaires consisting of demographic and clinical characteristics, EORTC QLQ-C30, Adult Hope Scale, Resilience Scale-14 and Life Orientation Scale-Revised from July 2013 to July 2014. Pearson's correlation and hierarchical regression analyses were performed to explore the effects of related factors. Hope, resilience and optimism were significantly associated with quality of life. Hierarchical regression analyses indicated that hope, resilience and optimism as a whole accounted for 9.8, 24.4 and 21.9% of the variance in the global health status, functioning status and symptom status, respectively. The low level of quality of life for Chinese renal carcinoma patients should receive more attention from Chinese medical institutions. Psychological interventions to increase hope, resilience and optimism may be essential to enhancing the quality of life of Chinese cancer patients.

The purpose of this prospective study was to evaluate the swallowing performance of patients with head and neck cancer treated with parotid-sparing intensity-modulated radiotherapy (IMRT). Sixty-two patients were recruited. Data were collected before and up to 12 months after treatment. Measures included the Performance Status Scale for head and neck cancer (PSS-HN Normalcy of Diet and Eating in Public subscales), tube feeding status, and 100 mL water swallow test (WST) volume and capacity scores. There was a significant reduction in PSS-HN and WST scores from baseline to 3 months (p < .001). Significant improvements were observed up to 12 months on the PSS-HN. Swallowing volume and capacity scores recovered but did not reach statistical significance. Tube feeding was not required in 47% of the patients. IMRT significantly impacts on swallowing performance, although there is a trend for improvement up to 12 months after treatment. Our data support a case-by-case approach to tube feeding. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1436-E1444, 2016. © 2015 Wiley Periodicals, Inc.

The population of preterm infants is increasing and resources available for follow-up are limited. Early markers are needed to identify children who will show major as well as more subtle neurodevelopmental impairments. Such a challenge could be achieved with the Amiel-Tison Neurological Assessment at Term (ATNAT). This study assesses the usefulness of the ATNAT in the prediction of developmental problems at two years of corrected age (CA) in infants born between 29 and 37 weeks of gestation. Inclusion criteria were: gestational age between 29(0/7) and 36(6/7) weeks inclusively, birth weight below 2500g and minimal 24-hour stay in the Neonatal Intensive Care Unit of Sainte-Justine Hospital. A sample of 147 was prospectively recruited and assessed at two ages: at term with the ATNAT and at 24months CA with Bayley Scales of Infant Development-II. No major impairment such as cerebral palsy and no neurosensory impairment were observed. Developmental delay defined by an index<70 on the mental or psychomotor scale was reported respectively in 6.2% and 5.4% of the cohort. Significant differences in mental, psychomotor and behavioral performances were found according to neurological status. Neurological status was the only variable to enter the predictive model for psychomotor and behavioral indexes. Gender and neurological status remained in the predictive model for mental performance. This study supports the inclusion of the ATNAT among the eligibility criteria for systematic neurodevelopmental surveillance as it allows early identification of infants at higher risk of low developmental performances at 24months CA.

Background Oral health and academic performance are important contributing factors for a student’s professional life. Countless factors affect both, among which sleep, vitality and fatigue are less explored areas that also have a strong impact. Objective The objective of the study was to assess the association of sleep disturbances, fatigue and vitality with self reported oral health status, oral hygiene habits and academic performance of dental students of Udaipur. Methods A descriptive cross-sectional study was conducted among undergraduate and postgraduate dental students of Udaipur. Self-administered structured questionnaire was used to assess the psychological factors, vitality, sleep quality, fatigue, self reported oral health status, habits and academic performance. Analysis of variance and stepwise multiple linear regression were utilized for statistical analysis with 95% confidence level and 5% level of significance. Results Of the 230 participants, 180 (78.3%) were undergraduates and 50 (21.7%) were postgraduates. Among them, females showed higher scores in disturbed sleep index (2.69±2.14) as compared to males (2.45±1.91). Respondents who had “Poor” dental health, scored more in disturbed sleep index (3.15±1.64) and fatigue scale (20.00±4.88). Subjects who flossed “everyday”, were found to have good sleep and more energy (p=0.01) and those who assessed themselves as excellent students scored more in the Vitality Scale (p=0.01) and less in the Sleep index (p=0.01). Conclusion The present study confirms that disturbed sleep, aliveness and fatigue, all are interlinked with each other and are imperative factors having the potential to alter the oral health status, habits and academics of dental students.

Status and Prospects for Indirect Dark Matter Searches with the Fermi Large Area Telescope

NASA Astrophysics Data System (ADS)

Charles, Eric; Fermi-LAT Collaboration

2014-01-01

During the first five years of operation of the Fermi Large Area Telescope (LAT) the LAT collaboration has performed numerous searches for signatures of Dark Matter interactions in both gamma-ray and cosmic-ray data. These searches feature many different target types, including dwarf spheroidal galaxies, galaxy clusters, the Milky Way halo and inner Galaxy and unassociated LAT sources. They make use of a variety of techniques, and have been performed in both the spatial and spectral domains, as well as via less conventional strategies such as examining the potential Dark Matter contribution to both large scale and small scale anisotropies. To date no clear gamma-ray or cosmic-ray signal from dark matter annihilation or decay has been observed, and the deepest current limits for annihilation exclude many Dark Matter particle models with the canonical thermal relic cross section and masses up to 30 GeV. In this contribution we will briefly review the status of each of the searches by the LAT collaboration. We will also discuss the limiting factors for the various search strategies and examine the prospects for the future.

The assessment of quality of life (QOL) is an important part of cachexia management for cancer patients. Functional assessment of anorexia-cachexia therapy (FAACT), a specific QOL instrument for cachexia patients, has not been validated in Chinese population. The aim of this study was to validate the FAACT scale in Chinese cancer patients for its future use. Eligible cancer patients were included in our study. Patients' demographic and clinical characteristics were collected from the electronic medical records. Patients were asked to complete the Chinese version of FAACT scale and the MD Anderson symptom inventory (MDASI), and then the reliability and validity were analyzed. A total of 285 patients were enrolled in our study, data of 241 patients were evaluated. Coefficients of Cronbach's alpha, test-retest and split-half analyses were all greater than 0.8, which indicated an excellent reliability for FAACT scale. In item-subscale correlation analysis and factor analysis, good construct validity for FAACT scale was found. The correlation between FAACT and MDASI interference subscale showed reasonable criterion-related validity, and for further clinical validation, the FAACT scale showed excellent discriminative validity for distinguishing patients in different cachexia status and in different performance status. The Chinese version of FAACT scale has good reliability and validity and is suitable for measuring QOL of cachexia patients in Chinese population.

Epilepsy is the most common non-infectious neurologic disease in developing countries such as Africa, including Nigeria. This study was designed to assess the intellectual performance of patients with epilepsy (PWE) in Nigeria hoping that the result will serve as the basis for educational, vocational, and social counseling. Forty-one PWE were studied along with 41 age-, sex- and education-matched healthy controls. A questionnaire was developed and applied to all subjects and history was taken from patients and eyewitness. The intellectual function of each subject was assessed with the aid of Wechsler Adult Intelligence Scale adapted for Nigerians. All patients subsequently had electroencephalography (EEG) performed and the EEG findings were noted. SPSS statistical package was used to analyze the data. The PWE performed poorly on the verbal IQ, performance IQ, and full scale IQ scores when compared with controls (P < 0.05) and 20% of PWE had mental retardation. Long duration of epilepsy, long duration of antiepileptic drug therapy, younger age at onset of epilepsy, increased frequency of seizures, and low educational status were found to have negative impacts on intellectual performance in PWE (P < 0.05) while seizure types and type of antiepileptic drugs (carbamazepine or phenytoin) did not influence intellectual performance. This study shows that PWE had significant intellectual impairment when compared with controls. In addition, long duration of epilepsy, long duration of AED therapy, earlier age of onset, increased seizure frequency, and low educational status had a negative impact on intellectual functioning in PWE.

An objective measure of physical function of elderly outpatients. The Physical Performance Test.

PubMed

Reuben, D B; Siu, A L

1990-10-01

Direct observation of physical function has the advantage of providing an objective, quantifiable measure of functional capabilities. We have developed the Physical Performance Test (PPT), which assesses multiple domains of physical function using observed performance of tasks that simulate activities of daily living of various degrees of difficulty. Two versions are presented: a nine-item scale that includes writing a sentence, simulated eating, turning 360 degrees, putting on and removing a jacket, lifting a book and putting it on a shelf, picking up a penny from the floor, a 50-foot walk test, and climbing stairs (scored as two items); and a seven-item scale that does not include stairs. The PPT can be completed in less than 10 minutes and requires only a few simple props. We then tested the validity of PPT using 183 subjects (mean age, 79 years) in six settings including four clinical practices (one of Parkinson's disease patients), a board-and-care home, and a senior citizens' apartment. The PPT was reliable (Cronbach's alpha = 0.87 and 0.79, interrater reliability = 0.99 and 0.93 for the nine-item and seven-item tests, respectively) and demonstrated concurrent validity with self-reported measures of physical function. Scores on the PPT for both scales were highly correlated (.50 to .80) with modified Rosow-Breslau, Instrumental and Basic Activities of Daily Living scales, and Tinetti gait score. Scores on the PPT were more moderately correlated with self-reported health status, cognitive status, and mental health (.24 to .47), and negatively with age (-.24 and -.18). Thus, the PPT also demonstrated construct validity. The PPT is a promising objective measurement of physical function, but its clinical and research value for screening, monitoring, and prediction will have to be determined.

Mental status of the elderly receiving home health services and the associated stress of home helpers.

One hundred and ninety elderly people receiving home health service were investigated. The intellectual levels, depressive state evaluated by the Cornell scale for depression in dementia (CSDD) scale, abnormal behaviors evaluated by the dementia behavior disturbance (DBD) scale, and activities of daily living (ADL) were examined. These assessments were performed by 72 skilled home helpers who also assessed the severity of their own level of stress using the Burnout scale. The intellectual level and mood-related signs, based on the CSDD scale, of the elderly living with families or with a spouse were diminished significantly as compared to the elderly living alone. The elderly living with families also performed worse on all ADL categories except for visual acuity as compared to the elderly living with a spouse or living alone. There was no significant correlation between the Burnout scale score and age or frequency of working as a home helper. These results suggest that elderly people living with families as compared to the elderly living with a spouse or living alone have greater mental health needs as well as more profound physical limitations.

1983-01-01

This study report defines a set of tests and measurements required to characterize the performance of a Large Space System (LSS), and to scale this data to other LSS satellites. Requirements from the Mobile Communication Satellite (MSAT) configurations derived in the parent study were used. MSAT utilizes a large, mesh deployable antenna, and encompasses a significant range of LSS technology issues in the areas of structural/dynamics, control, and performance predictability. In this study, performance requirements were developed for the antenna. Special emphasis was placed on antenna surface accuracy, and pointing stability. Instrumentation and measurement systems, applicable to LSS, were selected from existing or on-going technology developments. Laser ranging and angulation systems, presently in breadboard status, form the backbone of the measurements. Following this, a set of ground, STS, and GEO-operational were investigated. A third scale (15 meter) antenna system as selected for ground characterization followed by STS flight technology development. This selection ensures analytical scaling from ground-to-orbit, and size scaling. Other benefits are cost and ability to perform reasonable ground tests. Detail costing of the various tests and measurement systems were derived and are included in the report.

Oxidative stress is a pathophysiological mechanism potentially involved in psychiatric disorders. The objective of this study was to assess the relationship between total antioxidant status (TAS) and the functional status of patients with a first episode of psychosis at the onset of the disease. For this purpose, a sample of 70 patients aged between 9 and 17 years with a first episode of psychosis were followed up for a period of two years. Blood samples were drawn to measure TAS levels at three time points: at baseline, at one year, and at two years. Clinical symptoms and functioning were also assessed at the same time points using various scales. Linear regression analysis was performed to investigate the relationship between TAS and clinical status at each assessment, adjusting for potential confounding factors. The distribution of clinical variables was grouped in different percentiles to assess the dose-response in the relation between clinical variables and TAS. At baseline, patient's score on Children's Global Assessment Scale (CGAS) was directly and significantly associated with TAS with a monotonic increase in percentiles, and surprising this association was reversed after one and two years of follow-up with a monotonic decrease. In summary at the onset of the illness, TAS is positively related to clinical status, whereas as the illness progresses this correlation is reversed and becomes negative. This may be the result of an adaptive response. PMID:29698400

Dyspnoea is the most common symptom associated with poor quality of life in patients affected by Chronic Obstructive Pulmonary Disease (COPD). While COPD severity is commonly staged by lung function, the Medical Research Council (MRC) dyspnoea scale has been proposed as a more clinically meaningful method of quantifying disease severity in COPD. We wished to assess whether this scale might also be useful during telephone surveys as a simple surrogate marker of perceived health status in elderly patients with COPD. We conducted a comprehensive health status assessment by telephone survey of 200 elderly patients who had a physician diagnosis of COPD. The telephone survey contained 71 items and explored such domains as educational level, financial status, living arrangements and social contacts, co-morbid illness, and the severity and the impact of COPD on health status. Patients were categorized according to the reported MRC score: mild dyspnoea (MRC scale of 1), moderate dyspnoea (MRC scale of 2 and 3), or severe dyspnoea (MRC of 4 and 5). Deterioration in most of the recorded indicators of health status correlated with an increasingly severe MRC score. This was most evident for instrumental activities of daily living (IADL), perceived health and emotional status, pain-related limitations, limitations in social life, hospital admissions in preceding year and prevalence of most co-morbidities. The MRC dyspnoea scale is a reliable index of disease severity and health status in elderly COPD patients which should prove useful for remote monitoring of COPD and for rating health status for epidemiological purposes.

Nutrition is one of many factors affecting the cognitive development of children. In Cambodia, 55% of children <5 y were anemic and 40% stunted in 2010. Currently, no data exists on the nutritional status of Cambodian school-aged children, or on how malnutrition potentially affects their cognitive development. To assess the anthropometric and micronutrient status (iron, vitamin A, zinc, iodine) of Cambodian schoolchildren and their associations with cognitive performance. School children aged 6-16 y (n = 2443) from 20 primary schools in Cambodia were recruited. Anthropometry, hemoglobin, serum ferritin, transferrin receptors, retinol-binding protein and zinc concentrations, inflammation status, urinary iodine concentration and parasite infection were measured. Socio-economic data were collected in a sub-group of children (n = 616). Cognitive performance was assessed using Raven's Colored Progressive Matrices (RCPM) and block design and picture completion, two standardized tests from the Wechsler Intelligence Scale for Children (WISC-III). The prevalence of anemia, iron, zinc, iodine and vitamin A deficiency were 15.7%; 51.2%, 92.8%, 17.3% and 0.7% respectively. The prevalence of stunting was 40.0%, including 10.9% of severe stunting. Stunted children scored significantly lower than non-stunted children on all tests. In RCPM test, boys with iron-deficiency anemia had lower scores than boys with normal iron status (-1.46, p<0.05). In picture completion test, children with normal iron status tended to score higher than iron-deficient children with anemia (-0.81; p = 0.067) or without anemia (-0.49; p = 0.064). Parasite infection was associated with an increase in risk of scoring below the median value in block design test (OR = 1.62; p<0.05), and with lower scores in other tests, for girls only (both p<0.05). Poor cognitive performance of Cambodian school-children was multifactorial and significantly associated with long-term (stunting) and current nutritional status indicators (iron status), as well as parasite infection. A life-cycle approach with programs to improve nutrition in early life and at school-age could contribute to optimal cognitive performance.

The purpose of this study was to describe the influence of organizational variables on hospital staff nurses' job performance as reported by staff nurses in two cities in Turkey. Hospital ownership status, employment status were examined for their effect on this influence. The reported influence of organizational variables on job performance was measured by a questionnaire developed for this study. Nurses were asked to evaluate the influence of 28 organizational variables on their job performance using a five-point Likert-type scale (1- Never effective, 5- Very effective). The study used comparative and descriptive study design. The staff nurses who were included in this study were 831 hospital staff nurses. Descriptive statistics, frequencies, t-test, ANOVA and factor analysis were used for data analysis. The study showed the relative importance of the 28 organizational variables in influencing nurses' job performance. Nurses in this study reported that workload and technological support are the most influential organizational variables on their job performance. Factor analysis yielded a five-factor model that explained 53.99% of total variance. Administratively controllable influence job organizational variables influence job performance of nurses in different magnitude.

OBJECTIVES. The level of children’s motor skill proficiency may be an important determinant of their physical activity behaviors. This study assessed the efficacy of an intervention on gross motor skill performance, physical activity, and weight status of preschoolers. METHOD. The Food Friends: Get Movin’ With Mighty Moves® program was conducted in four Head Start centers. Measurements included the Peabody Developmental Motor Scales, pedometer counts, and body mass index (BMI) z scores. RESULTS. The intervention led to significant changes in gross motor skills in the treatment group (n = 98) compared with the control group (n = 103) and was a strong predictor of overall gross motor performance (gross motor quotient), locomotor, stability, and object manipulation skills. No intervention effect was found for physical activity levels or weight status. CONCLUSION. The intervention dose was adequate for enhancing gross motor skill performance but not for increasing physical activity levels or reducing BMI. PMID:23245780

Implications of the change in confinement status of a heterogeneous aquifer for scale-dependent dispersion and mass-transfer processes

A series of experimental tracer tests were performed to explore the implications of the change in the pressure status of a heterogeneous bimodal aquifer for scale-dependent dispersion and mass-transfer processes. The sandbox was filled with sands and gravel channels and patches to form an alluvial-like bimodal aquifer. We performed multiple injections of a conservative tracer from 26 different locations of the sandbox and interpreted the resulting depth-integrated breakthrough curves (BTCs) at the central pumping well to obtain a scale-dependent distribution of local and field-integrated apparent longitudinal dispersivity (respectively, αLloc and αLapp). We repeated the experiments under confined (CS) and unconfined (UNS) pressure status, keeping the same heterogeneous configuration. Results showed that αLloc(associated with transport through gravel zones) was poorly influenced by the change in aquifer pressure and the presence of channels. Instead, αLapp(i.e. macrodispersion) strongly increased when changing from CS to UNS. In specific, we found αLapp ≈ 0.03 r for the CS and αLapp ≈ 0.15 r for the UNS (being r the distance from the well). Second-to-fourth-order temporal moments showed strong spatial dependence in the UNS and no spatial dependence in the CS. These results seem consistent with a ;vadose-zone-driven; kinetic mass-transfer process occurring in the UNS but not in the CS. The vadose zone enhances vertical flow due to the presence of free surface and large contrasts in hydraulic conductivity triggered by the desaturation of gravel channels nearby the pumping well. The vadose zone enhances vertical mixing between gravel and sands and generates BTC tailing. In the CS vertical mixing is negligible and anomalous transport is not observed.

Relationship status: Scales for assessing the vitality of late adolescents' relationships with their parents.

PubMed

Klos, D S; Paddock, J R

1978-12-01

Three criteria for assessing relationship status were proposed: self-disclosure despite the risk of parental disapproval; openness to critical feedback from parents; constructive confrontation when angry with parents. These concepts were operationalized as narratives of nine interpersonal dilemmas, to which late adolescents responded by indicating "What would you do if you were in this situation?" Reliable example-anchored scales were constructed from the responses of one sample of college students and then cross-validated with two other samples. Social class had a significant but small effect on the relationship status scores; but age and sex of adolescent and sex of parent did not. The patterns of correlations of the Relationship Status Scales among themselves and with the Parent-Child Relations Questionnaire, the College Self-Expression Scale, the Fear of Negative Evaluation Scale, and Hogan's Empathy Scale were interpreted as evidence of construct validity.

Inequality within partner relationships is associated with HIV acquisition and gender violence, but little is known about more pervasive effects on women's health. We performed a cross-sectional analysis of associations between sexual relationship power and nutritional status among women in Uganda. Participants completed questionnaires and anthropometric measurements. We assessed sexual relationship power using the Sexual Relationship Power Scale (SRPS). We performed logistic regression to test for associations between sexual relationship power and poor nutritional status including body mass index, body fat percentage, and mid-upper arm circumference. Women with higher sexual relationship power scores had decreased odds of low body mass index (OR 0.29, p = 0.01), low body fat percentage (OR 0.54, p = 0.04), and low mid-upper arm circumference (OR 0.22, p = 0.01). These relationships persisted in multivariable models adjusted for potential confounders. Targeted interventions to improve intimate partner relationship equality should be explored to improve health status among women living with HIV in rural Africa.

Final Scientific Report: A Scalable Development Environment for Peta-Scale Computing

2013-02-22

This document is the final scientific report of the project DE-SC000120 (A scalable Development Environment for Peta-Scale Computing). The objective of this project is the extension of the Parallel Tools Platform (PTP) for applying it to peta-scale systems. PTP is an integrated development environment for parallel applications. It comprises code analysis, performance tuning, parallel debugging and system monitoring. The contribution of the Juelich Supercomputing Centre (JSC) aims to provide a scalable solution for system monitoring of supercomputers. This includes the development of a new communication protocol for exchanging status data between the target remote system and the client running PTP.more » The communication has to work for high latency. PTP needs to be implemented robustly and should hide the complexity of the supercomputer's architecture in order to provide a transparent access to various remote systems via a uniform user interface. This simplifies the porting of applications to different systems, because PTP functions as abstraction layer between parallel application developer and compute resources. The common requirement for all PTP components is that they have to interact with the remote supercomputer. E.g. applications are built remotely and performance tools are attached to job submissions and their output data resides on the remote system. Status data has to be collected by evaluating outputs of the remote job scheduler and the parallel debugger needs to control an application executed on the supercomputer. The challenge is to provide this functionality for peta-scale systems in real-time. The client server architecture of the established monitoring application LLview, developed by the JSC, can be applied to PTP's system monitoring. LLview provides a well-arranged overview of the supercomputer's current status. A set of statistics, a list of running and queued jobs as well as a node display mapping running jobs to their compute resources form the user display of LLview. These monitoring features have to be integrated into the development environment. Besides showing the current status PTP's monitoring also needs to allow for submitting and canceling user jobs. Monitoring peta-scale systems especially deals with presenting the large amount of status data in a useful manner. Users require to select arbitrary levels of detail. The monitoring views have to provide a quick overview of the system state, but also need to allow for zooming into specific parts of the system, into which the user is interested in. At present, the major batch systems running on supercomputers are PBS, TORQUE, ALPS and LoadLeveler, which have to be supported by both the monitoring and the job controlling component. Finally, PTP needs to be designed as generic as possible, so that it can be extended for future batch systems.« less

Patients with nonobstructive coronary artery disease (NOCAD; wall irregularities, stenosis <60%), and women with NOCAD in particular, remain underinvestigated. We examined sex and gender (S&G) differences in health status, psychological distress, and personality between patients with NOCAD and the general population, as well as S&G differences within the NOCAD population. In total, 523 patients with NOCAD (61±9 years, 52% women) were included via coronary angiography and computed tomography as part of the TWIST (Tweesteden Mild Stenosis) study. Generic health status (12-item Short Form physical and mental scales and fatigue), psychological distress (Hospital Anxiety and Depression Scale anxiety and depressive symptoms and Global Mood Scale negative and positive affect), and personality (Type D personality) were compared between patients with NOCAD and an age- and sex-matched group of 1347 people from the general population. Frequency matching was performed to obtain a similar sex distribution in each age-decile group. Both men and women with NOCAD reported impaired health status, more psychological distress, and Type D personality compared with men and women in the reference group. Women reported more psychosocial distress compared with men, but no significant sex-by-group interaction effects were observed. Women with NOCAD reported impaired health status, more anxiety, and less positive affect, but no differences in depressive symptoms, angina, or Type D personality when compared with men with NOCAD. Age, education, employment, partner, and alcohol use explained these S&G differences within the NOCAD group. In both men and women, NOCAD was associated with impaired health status, more psychological distress, and Type D personality when compared with a reference population. Factors reflecting S&G differences explained these S&G findings in patient-reported outcomes. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01788241. © 2016 The Authors.

We studied the transition from elementary to middle school for 74 fifth-grade students. Specifically, we examined how behavioral risk evident in the elementary years, as measured by the "Student Risk Screening Scale" (SRSS), impacts students transitioning from elementary to middle school. First, we examined how student risk status shifts…

Detecting symptom exaggeration in combat veterans using the MMPI-2 symptom validity scales: a mixed group validation.

Although validity scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) have proven useful in the detection of symptom exaggeration in criterion-group validation (CGV) studies, usually comparing instructed feigners with known patient groups, the application of these scales has been problematic when assessing combat veterans undergoing posttraumatic stress disorder (PTSD) examinations. Mixed group validation (MGV) was employed to determine the efficacy of MMPI-2 exaggeration scales in compensation-seeking (CS) and noncompensation-seeking (NCS) veterans. Unlike CGV, MGV allows for a mix of exaggerating and nonexaggerating individuals in each group, does not require that the exaggeration versus nonexaggerating status of any individual be known, and can be adjusted for different base-rate estimates. MMPI-2 responses of 377 male veterans were examined according to CS versus NCS status. MGV was calculated using 4 sets of base-rate estimates drawn from the literature. The validity scales generally performed well (adequate sensitivity, specificity, and efficiency) under most base-rate estimations, and most produced cutoff scores that showed adequate detection of symptom exaggeration, regardless of base-rate assumptions. These results support the use of MMPI-2 validity scales for PTSD evaluations in veteran populations, even under varying base rates of symptom exaggeration.

To cross-culturally adapt and validate the Spanish-language version of the SARC-F in Mexican community-dwelling older adults. Cross-sectional analysis of a prospective cohort. The FraDySMex study, a 2-round evaluation of community-dwelling adults from 2 municipalities in Mexico City. Participants were 487 men and women older than 60 years, living in the designated area in Mexico City. Information from questionnaires regarding demographic characteristics, comorbidities, mental status, nutritional status, dependence in activities of daily living, frailty, and quality of life. Objective measurements of muscle mass, strength and function were as follows: skeletal muscle mass index (SMI) was taken using dual-energy x-ray, grip strength using a hand dynamometer, 6-meter gait speed using a GAIT Rite instrumented walkway, peak torque and power for knee extension using a isokinetic dynamometer, lower extremity functioning measured by the Short Physical Performance Battery (SPPB), and balance using evaluation on a foam surface, with closed eyes, in the Modified Clinical Test of Sensory Integration. The SARC-F scale translated to Spanish and the consensus panels' criteria from European, international, and Asian sarcopenia working groups were applied to evaluate sarcopenia. The Spanish language version of the SARC-F scale showed reliability (Cronbach alfa = 0.641. All items in the scale correlated to the scale's total score, rho = 0.43 to 0.76), temporal consistency evaluated by test-retest (CCI = 0.80), criterion validity when compared to the consensus panels' criteria (high specificity and negative predictive values). The scale was also correlated to other measures related to sarcopenia (such as age, quality of life, self-rated health status, cognition, dependence in activities of daily living, nutritional status, depression, gait speed, grip strength, peak torque and power for knee extension, SPPB, balance, SMI, and frailty). The SARC-F scale was successfully adapted to Spanish language and validated in community-dwelling Mexican older adults. Copyright © 2016 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

This study assessed the general health, music performance anxiety (MPA), and coping methods of musicians working in six state orchestras in Turkey. All musicians working in the state symphony orchestras (n=384) were invited to participate in the study. In face-to-face interviews, the authors administered a questionnaire, which consisted of five sections: sociodemographic information, history of musical performance, health status, general health questionnaire-12 (GHQ-12), and MPA scale. Mann-Whitney U-test, Student's t-test, and Spearman's correlation test were used to analyze the questionnaire data. The 220 musicians who participated included 121 (55%) males and 99 (45%) females, with a mean age of 42.4±11.3 yrs. For musculoskeletal symptoms, 87.6% reported at least one symptom with the most common being pain. For general health status, the GHQ-12 showed 64% of musicians were at low risk, 18.7% at moderate risk, and 17.3% at high risk in terms of mental health. The prevalence of MPA before or during performance was 81.8%, and 60% of musicians stated that performance anxiety negatively affected their performances. Results indicate that musicians working in Turkish state symphony orchestras encounter numerous health problems (tinnitus, hearing loss, musculoskeletal symptoms, etc.) due to their profession. No specific health support is provided, especially education and health service provision.

The National Research Council issued Electricity from Renewables: Status, Prospects, and Impediments in 2009 as part of the America's Energy Future Study. The panel that authored this report, the Panel on Electricity from Renewable Sources, worked from 2007 to 2009 gathering information and analysis on the cost, performance and impacts of renewable electricity resources and technologies in the United States. The panel considered the magnitude and distribution of the resource base, the status of renewable electricity technologies, the economics of these technologies, their environmental footprint, and the issues related to scaling up renewables deployment. In its consideration of the future potential for renewable electricity, the panel emphasizes policy, technology, and capital equally because greatly scaling up renewable electricity encounters significant issues that go beyond resource availability or technical capabilities. Here we provide a summary of this report and discuss several recent trends that impact renewable electricity.

A systematic methodology, Comprehensive Assessment for Tracking Community Health (CATCH), for analyzing the health status of communities has been under development at the University of South Florida since the early 1990s. CATCH draws 226 health status indicators from multiple data sources and uses an innovative comparative framework and weighted evaluation criteria to produce a rank-ordered list of community health problems. CATCH has been applied successfully in many Florida counties; focusing attention on high priority health issues and measuring the impact of health expenditures on community health status outcomes. Previously performed manually, we are using information technology (IT) to automate the CATCH methodology with a full-scale data warehouse, user-friendly forms and reports, and extended analysis and data mining capabilities. The automated system, CATCH/IT, will reduce the time to prepare community health status reports from months to days. In this paper, we present the current status of the project, along with the principal research and development issues and future directions of the project. PMID:9929220

Objectives Malnutrition is prevalent among cancer patients, and maybe correlated with altered quality of life. The objective of this study is to determine wether quality of life among cancer patients on chemotherapy at the National Kidney and Transplant Institute- Cancer Unit differs from patients with normal nutrition based on the Subjective Global Assessment scale. Methods A cross sectional study was conducted among cancer patients admitted for chemotherapy at the National Kidney and Transplant Institute-Cancer Unit from January to May 2011. Demographic profile, performance status by Eastern Cooperative Oncology Group performance scale, nutritional status assessment by Subjective Global Assessment, and quality of life assessment by the European Organization for Research and Treatment of Cancer QoL-30 core module were obtained. Descriptive statistics and ANOVA were performed for analysis of quality of life parameters and nutritional status. Results A total of 97 subjects were included in this study, 66 subjects (68.04%) were females and 31 (31.96%) were males. Mean age was 54.55 ± 11.14 years, while mean performance status by the Eastern Cooperative Oncology Group classification was 0.88 ± 0.83 with a range of 0-3. According to the Subjective Global Assessment, there were 58 patients with SGA A, classified to have adequate nutrition, and 39 patients (40.21%) were considered malnourished. Among these 39 patients, 32 were classified SGA-B (moderately malnourished) and 7 were classified SGA C (severely malnourished) mean global quality of life was 68.73 ± 19.05. Results from ANOVA test revealed that patients were statistically different across the Subjective Global Assessment groups according to global quality of life (p<0.001), physical (p<0.001), role (p<0.001), emotional (p<0.001), and cognitive functioning (p<0.001); fatigue (p<0.001), nausea and vomiting (p<0.001), pain (p<0.001), insomnia (p<0.001), and appetite loss (p<0.001). Conclusion Global quality of life and its parameters: physical state, role, emotional state, cognitive functioning, cancer fatigue, nausea and vomiting, pain, insomnia, and loss of appetite were statistically different across all Subjective Global Assessment groups. Moreover, there was no difference between financial difficulties, social functioning, constipation and diarrhea among the Subjective Global Assessment groups. PMID:23904921

Functional health, a reliable parameter of the impact of disease, should be used systematically to assess prognosis in paediatric intensive care units (PICU). Developing scales for the assessment of functional health is therefore essential. The Paediatric Overall and Cerebral Performance Category (POPC, PCPC) scales have traditionally been used in paediatric studies. The new Functional Status Scale (FSS) was designed to provide more objective results. This study aims to confirm the validity of the FSS compared to the classic POPC and PCPC scales, and to evaluate whether it may also be superior to the latter in assessing of neurological function. We conducted a retrospective descriptive study of 266 children with neurological diseases admitted to intensive care between 2012 and 2014. Functional health at discharge and at one year after discharge was evaluated using the PCPC and POPC scales and the new FSS. Global FSS scores were found to be well correlated with all POPC scores (P<.001), except in category 5 (coma/vegetative state). Global FSS score dispersion increases with POPC category. The neurological versions of both scales show a similar correlation. Comparison with classic POPC and PCPC categories suggests that the new FSS scale is a useful method for evaluating functional health in our setting. The dispersion of FSS values underlines the poor accuracy of POPC-PCPC compared to the new FSS scale, which is more disaggregated and objective. Copyright © 2017 Sociedad Española de Neurología.

Objective To support efforts to address vaccine hesitancy, we sought to validate a brief measure of vaccination confidence using a large, nationally representative sample of parents. Methods We analyzed weighted data from 9,018 parents who completed the 2010 National Immunization Survey-Teen, an annual, population-based telephone survey. Parents reported on the immunization history of a 13- to 17-year-old child in their households for vaccines including tetanus, diphtheria, and acellular pertussis (Tdap), meningococcal, and human papillomavirus (HPV) vaccines. For each vaccine, separate logistic regression models assessed associations between parents’ mean scores on the 8-item Vaccination Confidence Scale and vaccine refusal, vaccine delay, and vaccination status. We repeated analyses for the scale’s 4-item short form. Results One quarter of parents (24%) reported refusal of any vaccine, with refusal of specific vaccines ranging from 21% for HPV to 2% for Tdap. Using the full 8-item scale, vaccination confidence was negatively associated with measures of vaccine refusal and positively associated with measures of vaccination status. For example, refusal of any vaccine was more common among parents whose scale scores were medium (odds ratio [OR] = 2.08, 95% confidence interval [CI], 1.75–2.47) or low (OR = 4.61, 95% CI, 3.51–6.05) versus high. For the 4-item short form, scores were also consistently associated with vaccine refusal and vaccination status. Vaccination confidence was inconsistently associated with vaccine delay. Conclusions The Vaccination Confidence Scale shows promise as a tool for identifying parents at risk for refusing adolescent vaccines. The scale’s short form appears to offer comparable performance.

Using a relatively new statistical paradigm, Optimal Data Analysis (ODA; Yarnold & Soltysik, 2005), this research demonstrated that newly developed scales for the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and MMPI-2 Restructured Form (MMPI-2-RF) specifically designed to assess over-reporting of cognitive and/or somatic symptoms were more effective than the MMPI-2 F-family of scales in predicting effort status on tests of cognitive functioning in a sample of 288 military members. ODA demonstrated that when all scales were performing at their theoretical maximum possible level of classification accuracy, the Henry Heilbronner Index (HHI), Response Bias Scale (RBS), Fake Bad Scale (FBS), and the Symptom Validity Scale (FBS-r) outperformed the F-family of scales on a variety of ODA indexes of classification accuracy, including an omnibus measure (effect strength total, EST) of the descriptive and prognostic utility of ODA models developed for each scale. Based on the guidelines suggested by Yarnold and Soltysik for evaluating effect strengths for ODA models, the newly developed scales had effects sizes that were moderate in size (37.66 to 45.68), whereas the F-family scales had effects strengths that ranged from weak to moderate (15.42 to 32.80). In addition, traditional analysis demonstrated that HHI, RBS, FBS, and FBS-R had large effect sizes (0.98 to 1.16) based on Cohen's (1988) suggested categorization of effect size when comparing mean scores for adequate versus inadequate effort groups, whereas F-family of scales had small to medium effect sizes (0.25 to 0.76). The MMPI-2-RF Infrequent Somatic Responses Scale (F(S)) tended to perform in a fashion similar to F, the best performing F-family scale.

The peripheral artery questionnaire: a new disease-specific health status measure for patients with peripheral arterial disease.

The most common indication for treating patients with peripheral arterial disease is to improve their health status: their symptoms, function, and quality of life. Quantifying health status requires a valid, reproducible, and sensitive disease-specific measure. The Peripheral Artery Questionnaire (PAQ) is a 20-item questionnaire developed to meet this need by quantifying patients' physical limitations, symptoms, social function, treatment satisfaction, and quality of life. Psychometric and clinical properties of the PAQ were evaluated in a prospective cohort study of 44 patients undergoing elective percutaneous peripheral revascularization. To establish reproducibility, 2 assessments were performed 2 weeks apart and before revascularization. The change in scores before and 6 weeks after revascularization were used to determine the instruments' responsiveness and were compared with the Short Form-36 and the Walking Impairment Questionnaire. A series of cross-sectional analyses were performed to establish the construct validity of the PAQ. The 7 domains of the PAQ were internally reliable, with Cronbach alpha = 0.80 to 0.94. The test-retest reliability analyses revealed insignificant mean changes of 0.6 to 2.3 points (P = not significant for all). Conversely, the change after revascularization ranged from 13.7 to 41.9 points (P < or =.001 for all), reflecting substantial sensitivity of the PAQ to clinical improvement. The PAQ Summary Scale was the most sensitive of all scales tested. Construct validity was established by demonstrating correlations with other measures of patient health status. The PAQ is a valid, reliable, and responsive disease-specific measure for patients with peripheral arterial disease. It may prove to be a useful end point in clinical trials and a potential aid in disease management.

This study aimed to estimate the prevalence of leisure-time physical activity and investigate its association with contextual characteristics of the social and physical environment in different socioeconomic statuses, using a household survey in Belo Horizonte, Minas Gerais State, Brazil (2008-2009). Leisure-time physical activity was measured by the International Physical Activity Questionnaire; and the social and physical environment by scales arising from perception of neighborhood attributes. Multilevel logistic regression analysis was performed separately for each socioeconomic status stratum. The overall prevalence of leisure-time physical activity was 30.2%, being 20.2% amongst participants of low socioeconomic status, 25.4% in the medium and 40.6% in the high socioeconomic status group. A greater perception of social cohesion was associated with increased leisure-time physical activity only amongst participants of the lowest socioeconomic status even after adjusting for individual characteristics. The results demonstrate the importance of social cohesion for the promotion of leisure-time physical activity in economically disadvantaged groups, supporting the need to stimulate interventions for enhancing social relationships in this population.

To investigate the status of subjective well-being (SWB) for medical staffs who contact with patients directly in a tertiary hospital.
 Staffs from a tertiary hospital in Hunan province were investigated the SWB Scale (SWBS-cc20) from 2012 to 2014.
 The scores of SWB for medical staffs are high (81.67±12.33). Among the 10 sub-dimensions of SWB, medical staffs performed the best in family atmosphere, personal growth, and interpersonal adaptation, while performed the worst in physical health, mental health and material contentment. Title, job nature, education and occupation significantly affected the status of SWB. Staffs who directly connected with patients have less scores of SWB than those who do not (t=-4.80, P<0.001). Moreover, they perform better in contentment (OR=0.079, 95% CI 1.278 to 2.214, P<0.001), but worse in mental health (OR=1.315, 95% CI 1.023 to 1.690, P<0.05) and physical health (OR=1.313, 95% CI 1.029 to 1.677, P<0.05).
 Medical staffs have high scores of SWB. Staffs who directly connected with patients have less scores of SWB than those who do not. Moreover, they perform better in contentment, but worse in mental health and physical health.

Screening California Current fishery management scenarios using the Atlantis end-to-end ecosystem model

End-to-end marine ecosystem models link climate and oceanography to the food web and human activities. These models can be used as forecasting tools, to strategically evaluate management options and to support ecosystem-based management. Here we report the results of such forecasts in the California Current, using an Atlantis end-to-end model. We worked collaboratively with fishery managers at NOAA’s regional offices and staff at the National Marine Sanctuaries (NMS) to explore the impact of fishery policies on management objectives at different spatial scales, from single Marine Sanctuaries to the entire Northern California Current. In addition to examining Status Quo management, we explored the consequences of several gear switching and spatial management scenarios. Of the scenarios that involved large scale management changes, no single scenario maximized all performance metrics. Any policy choice would involve trade-offs between stakeholder groups and policy goals. For example, a coast-wide 25% gear shift from trawl to pot or longline appeared to be one possible compromise between an increase in spatial management (which sacrificed revenue) and scenarios such as the one consolidating bottom impacts to deeper areas (which did not perform substantially differently from Status Quo). Judged on a coast-wide scale, most of the scenarios that involved minor or local management changes (e.g. within Monterey Bay NMS only) yielded results similar to Status Quo. When impacts did occur in these cases, they often involved local interactions that were difficult to predict a priori based solely on fishing patterns. However, judged on the local scale, deviation from Status Quo did emerge, particularly for metrics related to stationary species or variables (i.e. habitat and local metrics of landed value or bycatch). We also found that isolated management actions within Monterey Bay NMS would cause local fishers to pay a cost for conservation, in terms of reductions in landed value. However, this cost was minimal when local conservation actions were part of a concerted coast-wide plan. The simulations demonstrate the utility of using the Atlantis end-to-end ecosystem model within NOAA’s Integrated Ecosystem Assessment, by illustrating an end-to-end modeling tool that allows consideration of multiple management alternatives that are relevant to numerous state, federal and private interests.

This study was done to identify predictors of the fighting spirit or helplessness/hopelessness in the patients' mental adjustment to cancer. Cancer patients' characteristics like performance status, metastasis and duration of diagnosis with demographic factors, spiritual support and social support were used as predictors of a fighting spirit or helplessness/hopelessness. A total of 124 ambulatory cancer patients completed the Mental Adjustment to Cancer (MAC) scale and responded in a structured instrument about their characteristics, spiritual and social support. The results of multiple regression analysis revealed that confidence in the supporter (R(2)=.114, p=.000), duration of cancer diagnosis (R(2)=.041, p=.000) and faith (R(2)=.030, p=.000) were predictive of a fighting spirit (R(2)=.185, p=.000); whereas, education (R(2)=.074, p=.001), performance status (R(2)=.055, p=.000), satisfaction with social support (R(2)=.046, p=.000), and metastasis (R(2)=.037, p=.000) were predictive of helplessness/hopelessness (R(2)=.202, p=.000). Social support, spiritual support and disease related factors like metastasis, performance status, and duration of cancer diagnosis need to be considered in a psychosocial nursing intervention for a fighting spirit or helplessness/hopelessness.

The goals of the study were to determine the relationship of upper gastrointestinal symptoms with nutritional status and to assess their association with performance status in patients with advanced cancer. We studied 143 patients (50 F, 93 M, mean age 68 +/- 11 years, mean body mass index 22.39 +/- 4.3 kg/m(2)). Assessed symptoms were the following: anorexia, nausea, vomiting, dysphagia for solids, dysphagia for liquids, xerostomia, hypogeusia, dysgeusia, hiccup and chewing disturbances. We determined anthropometric parameters, daily energy intake and serum albumin, prealbumin and transferrin. The most common upper gastrointestinal symptoms were xerostomia (73%), anorexia (49%) and chewing disturbances (40%). Fifty-four percent of patients had weight loss greater than 10%. Seventy-three patients (51%) had daily energy intake lower than their resting energy expenditure. Mean serum prealbumin, albumin and transferrin were below normal range. Mean Eastern Cooperative Oncology Group performance status scale was 3.1 +/- 0.49. Symptoms were often strongly correlated, and usually, patients experienced at least three upper gastrointestinal symptoms at the same time. Anorexia, nausea and vomiting were the symptoms mostly correlated with other symptoms. A correlation was found between vomiting and hiccup. Energy intake (EI) was the nutritional parameter mostly affected by upper gastrointestinal symptoms; moreover, EI is the most predictive factor of upper gastrointestinal symptoms, particularly xerostomia, anorexia and dysphagia for solids. Upper gastrointestinal symptoms are linked to nutritional parameters: In particular, energy intake represents the most predictive variable of symptom occurrence. The performance status is not affected by upper gastrointestinal symptoms. A rigorous nutritional assessment and the managing of upper gastrointestinal symptoms are crucial in patients with advanced cancer.

In this regard, satellite-derived Ecosystem Functional Attributes (EFAs) offer a more integrative and quicker evaluation of ecosystem responses to environmental drivers and changes than climate and structural or compositional landscape attributes. Thus, EFAs may hold advantages as predictors in Species Distribution Models (SDMs) and for implementing multi-scale species monitoring programs. Here we describe a modelling framework to assess the predictive ability of EFAs as Essential Biodiversity Variables (EBVs) against traditional datasets (climate, land-cover) at several scales. We test the framework with a multi-scale assessment of habitat suitability for two plant species of conservation concern, both protected under the EU Habitats Directive, differing in terms of life history, range and distribution pattern (Iris boissieri and Taxus baccata). We fitted four sets of SDMs for the two test species, calibrated with: interpolated climate variables; landscape variables; EFAs; and a combination of climate and landscape variables. EFA-based models performed very well at the several scales (AUCmedian from 0.881±0.072 to 0.983±0.125), and similarly to traditional climate-based models, individually or in combination with land-cover predictors (AUCmedian from 0.882±0.059 to 0.995±0.083). Moreover, EFA-based models identified additional suitable areas and provided valuable information on functional features of habitat suitability for both test species (narrowly vs. widely distributed), for both coarse and fine scales. Our results suggest a relatively small scale-dependence of the predictive ability of satellite-derived EFAs, supporting their use as meaningful EBVs in SDMs from regional and broader scales to more local and finer scales. Since the evaluation of species' conservation status and habitat quality should as far as possible be performed based on scalable indicators linking to meaningful processes, our framework may guide conservation managers in decision-making related to biodiversity monitoring and reporting schemes.

To evaluate the linguistic and psychometric properties of the Functional Living Index-Cancer (FLIC) in assessing the quality of life of Chinese cancer patients. The English FLIC was translated into Traditional Chinese by the standard forward-backward procedure. After cognitive debriefing, a Traditional Chinese FLIC was administered to 500 cancer patients in a major public hospital in Hong Kong. Of which, 200 were invited to complete the questionnaire in 2 weeks. To identify a scale structure appropriate to Chinese, exploratory and confirmatory factor analyses were performed on two randomly split halves of the sample. We identified five scales of the Traditional Chinese FLIC which assess the physical, psychological, hardship, nausea and social aspects. These five scales and the overall scale demonstrated satisfactory fit and had the alpha coefficient ranged from 0.68 to 0.92. The intra-class correlation coefficient ranged from 0.67 to 0.88. In addition, all FLIC scales were negatively associated with the Eastern Cooperative Oncology Group performance status and, also except for the psychological scale, had lower scores in patients who were treated by chemotherapy. The Traditional Chinese FLIC is an appropriate health indicator for Chinese cancer patients.

We designed and validated a simple prehospital stroke scale to identify emergent large vessel occlusion (ELVO) in patients with acute ischemic stroke and compared the scale to other published scales for prediction of ELVO. A national historical test cohort of 3127 patients with information on intracranial vessel status (angiography) before reperfusion therapy was identified. National Institutes of Health Stroke Scale (NIHSS) items with the highest predictive value of occlusion of a large intracranial artery were identified, and the most optimal combination meeting predefined criteria to ensure usefulness in the prehospital phase was determined. The predictive performance of Prehospital Acute Stroke Severity (PASS) scale was compared with other published scales for ELVO. The PASS scale was composed of 3 NIHSS scores: level of consciousness (month/age), gaze palsy/deviation, and arm weakness. In derivation of PASS 2/3 of the test cohort was used and showed accuracy (area under the curve) of 0.76 for detecting large arterial occlusion. Optimal cut point ≥2 abnormal scores showed: sensitivity=0.66 (95% CI, 0.62-0.69), specificity=0.83 (0.81-0.85), and area under the curve=0.74 (0.72-0.76). Validation on 1/3 of the test cohort showed similar performance. Patients with a large artery occlusion on angiography with PASS ≥2 had a median NIHSS score of 17 (interquartile range=6) as opposed to PASS <2 with a median NIHSS score of 6 (interquartile range=5). The PASS scale showed equal performance although more simple when compared with other scales predicting ELVO. The PASS scale is simple and has promising accuracy for prediction of ELVO in the field. © 2016 American Heart Association, Inc.

Cognitive deficits are prevalent in people with schizophrenia and associated with functional impairments. In addition to antipsychotics, pharmacotherapy in schizophrenia often includes other psychotropics, and some of these agents possess anticholinergic properties, which may impair cognition. The objective of this study was to explore the association between medication anticholinergic burden and cognition in schizophrenia. Seven hundred five individuals with schizophrenia completed a neuropsychological battery comprising Judgment of Line Orientation Test, Wechsler Abbreviated Scale of Intelligence Matrix Reasoning, Continuous Performance Test-Identical Pairs Version, and the Brief Assessment of Cognition in Schizophrenia. Cognitive g and 3 cognitive factor scores that include executive function, memory/fluency, and speed of processing/vigilance, which were derived from a previously published analysis, were entered as cognitive variables. Anticholinergic burden was computed using 2 anticholinergic scales: Anticholinergic Burden Scale and Anticholinergic Drug Scale. Duration and severity of illness, antipsychotic dose, smoking status, age, and sex were included as covariates. Anticholinergic burden was associated with poorer cognitive performance in cognitive g, all 3 cognitive domains and most cognitive tasks in multivariate analyses. The associations were statistically significant, but the effect sizes were small (for Anticholinergic Burden Scale, Cohen f = 0.008; for Anticholinergic Drug Scale, Cohen f = 0.017). Although our results showed a statistically significant association between medications with anticholinergic properties and cognition in people with schizophrenia, the impact is of doubtful or minimal clinical significance.

Strong organizational support can promote a sense of well-being and positive work behaviors in nurses. However, despite the importance of organizational support in nursing, this topic remains unexplored in the Philippines. The aim of this study was to examine the impact of organizational support perceptions on nurses' work outcomes (organizational commitment, work autonomy, work performance, job satisfaction, job stress, and turnover intention). A descriptive, cross-sectional research design was adopted in this study to collect data from one hundred eighty (180) nurses in the Philippines during the months of September 2015 to December 2015. Seven standardized tools were used: the Job Satisfaction Index, the Job Stress Scale, the Burnout Measure Scale, the Work Autonomy Scale, the Six Dimension Scale of Nursing Performance, the Turnover Intention Inventory Scale, and the Perception of Organizational Support Scale. Nurses employed in government-owned hospitals perceived low levels of organizational support as compared to private hospitals. Significant correlations were identified between perceived organizational support (POS), hospital bed capacity, and nurses' work status. No significant correlations were found between perceived organizational supportand the six outcomes perceived by nurses in the Philippines (organizational commitment, work performance, job autonomy, job satisfaction, job stress, and turnover intention). Perceptions of organizational support were low in Filipino nurses compared to findings in other international studies. Perceived organizational support did not influence job outcomes in nurses. © 2018 Wiley Periodicals, Inc.

We investigated the effect of chronic renal failure on the emotional status, social and psychological adaptation and the cognitive status of patients and the effect of a programme to improve the psychosocial state of the patients; 40 renal dialysis patients and 40 healthy controls were included. We used the Emotional Status Scale, Psychosocial Adaptation Scale, the Primary Mental Abilities Test and the Memory Processes Scale for assessment of the participants. The controls had better emotional/cognitive status and psychosocial adaptation than the dialysis patients, a statistically significant difference. There were also statistically significant differences between the patients before and after the application of the programme.

to explore the relationship between socioeconomic status and subjective social status and explain how subjective social status predicts health in immigrant women. cross-sectional study based on data from 371 Latin American women (16-65 years old) from a total of 7,056 registered immigrants accessed through community partners between 2009-2010. Socioeconomic status was measured through education, income and occupation; subjective social status was measured using the MacArthur Scale, and perceived health, using a Likert scale. a weak correlation between socioeconomic and subjective social status was found. In the bivariate analysis, a significantly higher prevalence of negative perceived health in women with no education, low income, undocumented employment was observed. In the multivariate analysis, higher odds of prevalence of negative perceptions of health in the lower levels of the MacArthur scale were observed. No significant differences with the rest of the variables were found. the study suggests that subjective social status was a better predictor of health status than the socioeconomic status measurements. Therefore, the use of this measurement may be relevant to the study of health inequalities, particularly in socially disadvantaged groups such as immigrants.

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

The present study was aimed to validate two normalised short-form (SF) Mini-Nutritional Assessments (MNA) that contained either BMI (Taiwan version 1, T1) or calf circumference (CC; Taiwan version 2, T2) for rating the nutritional status of elderly Taiwanese. Both versions adopted Taiwanese anthropometric cut-offs, but T2 further had the BMI item replaced by CC. We compared the ability of the two SF in rating the nutritional status of 2674 elderly Taiwanese in the 1999 ‘Taiwan Longitudinal Survey on Aging’ with their respective full versions. We evaluated the agreement between the SF and full scales with weighted κ and performed Cox regression analysis for the follow-up 4-year mortality according to nutritional status rated at baseline. The results showed that the agreements between the respective SF and the full MNA were good (weighted κ: 0·679 for T1 and 0·667 for T2). Both SF performed well in predicting follow-up 4-year mortality relative to the full MNA. In conclusion, MNA-T1-SF and -T2-SF have good consistency with the full MNA and have quite comparable abilities in rating the nutritional status of elderly Taiwanese. Both SF versions appear appropriate for functioning as stand-alone units for rating the nutritional status of the elderly in community-living settings or the general population.

The present study validates a revised scale measuring individuals' level of the 'engagement in dietary behaviour' aspect of 'critical nutrition literacy' and describes how background factors affect this aspect of Norwegian tenth-grade students' nutrition literacy. Data were gathered electronically during a field trial of a standardised sample test in science. Test items and questionnaire constructs were distributed evenly across four electronic field-test booklets. Data management and analysis were performed using the RUMM2030 item analysis package and the IBM SPSS Statistics 20 statistical software package. Students responded on computers at school. Seven hundred and forty tenth-grade students at twenty-seven randomly sampled public schools were enrolled in the field-test study. The engagement in dietary behaviour scale and the self-efficacy in science scale were distributed to 178 of these students. The dietary behaviour scale and the self-efficacy in science scale came out as valid, reliable and well-targeted instruments usable for the construction of measurements. Girls and students with high self-efficacy reported higher engagement in dietary behaviour than other students. Socio-economic status and scientific literacy - measured as ability in science by applying an achievement test - did not correlate significantly different from zero with students' engagement in dietary behaviour.

For practical reasons all isotope measurements are performed on relative scales realized through the use of international, scale-defining primary standards. In fact these standards were materials (artefacts, similar to prototypes of meter and kg) selected based on their properties. The VPDB delta-13C scale is realised via two highest-level reference materials NBS19 and LSVEC, the first defining the scale and the second aimed to normalise lab-to-lab calibrations. These two reference materials (RMs) have been maintained and distributed by IAEA and NIST. The priority task is to maintain these primary RMs at the required uncertainty level, thus ensuring the long-term scale consistency. The second task is to introduce replacements when needed (currently for exhausted NBS19, work in progress). The next is to produce a family of lower level RMs (secondary, tertiary) addressing needs of various applications (with different delta values, in different physical-chemical forms) and their needs for the uncertainty; these RMs should be traceable to the highest level RMs. Presently three is a need for a range of RMs addressing existing and newly emerging analytical techniques (e.g. optical isotopic analysers) in form of calibrated CO2 gases with different delta-13C values. All that implies creating a family of delta-13C stable isotope reference materials. Presently IAEA works on replacement for NBS19 and planning new RMs. Besides, we found that LSVEC (introduced as second anchor for the VPDB scale in 2006) demonstrate a considerable scatter of its delta-13C value which implies a potential bias of the property value and increased value uncertainty which may conflict with uncertainty requirements for atmospheric monitoring. That is not compatible with the status of LSVEC, and therefore it should be replaced as soon as possible. The presentation will give an overview of the current status, the strategic plan of developments and the near future steps.

Recent translational research developments in Spinal Muscular Atrophy (SMA), outcome measure design and demands from regulatory authorities require that clinical outcome assessments are 'fit for purpose'. An international collaboration (SMA REACH UK, Italian SMA Network and PNCRN USA) undertook an iterative process to address discontinuity in the recorded performance of the Hammersmith Functional Motor Scale Expanded and developed a revised functional scale using Rasch analysis, traditional psychometric techniques and the application of clinical sensibility via expert panels. Specifically, we intended to develop a psychometrically and clinically robust functional clinician rated outcome measure to assess physical abilities in weak SMA type 2 through to strong ambulant SMA type 3 patients. The final scale, the Revised Hammersmith Scale (RHS) for SMA, consisting of 36 items and two timed tests, was piloted in 138 patients with type 2 and 3 SMA in an observational cross-sectional multi-centre study across the three national networks. Rasch analysis demonstrated very good fit of all 36 items to the construct of motor performance, good reliability with a high Person Separation Index PSI 0.98, logical and hierarchical scoring in 27/36 items and excellent targeting with minimal ceiling. The RHS differentiated between clinically different groups: SMA type, World Health Organisation (WHO) categories, ambulatory status, and SMA type combined with ambulatory status (all p < 0.001). Construct and concurrent validity was also confirmed with a strong significant positive correlation with the WHO motor milestones rs = 0.860, p < 0.001. We conclude that the RHS is a psychometrically sound and versatile clinical outcome assessment to test the broad range of physical abilities of patients with type 2 and 3 SMA. Further longitudinal testing of the scale with regards change in scores over 6 and 12 months are required prior to its adoption in clinical trials.

Gait and balance dysfunction frequently occurs early in the multiple sclerosis (MS) disease course. Hence, we sought to determine the longitudinal relationships among quantitative measures of gait and balance in individuals with MS. Fifty-seven ambulatory individuals with MS (28 relapsing-remitting, 29 progressive) were evaluated using posturography, quantitative sensorimotor and gait measures, and overall MS disability with the Expanded Disability Status Scale at each session. Our cohort's age was 45.8 ± 10.4 years (mean ± SD), follow-up time 32.8 ± 15.4 months, median Expanded Disability Status Scale score 3.5, and 56% were women. Poorer performance on balance measures was related to slower walking velocity. Two posturography measures, the anterior-posterior sway and sway during static eyes open, feet apart conditions, were significant contributors to walk velocity over time (approximate R(2) = 0.95), such that poorer performance on the posturography measures was related to slower walking velocity. Similarly, the anterior-posterior sway and sway during static eyes closed, feet together conditions were also significant contributors to the Timed 25-Foot Walk performance over time (approximate R(2) = 0.83). This longitudinal cohort study establishes a strong relationship between clinical gait measures and posturography. The data show that increases in static posturography and reductions in dynamic posturography are associated with a decline in walk velocity and Timed 25-Foot Walk performance over time. Furthermore, longitudinal balance measures predict future walking performance. Quantitative walking and balance measures are important additions to clinical testing to explore longitudinal change and understand fall risk in this progressive disease population. © 2015 American Academy of Neurology.

The cancer survival rate in Korea has substantially increased, necessitating the management of not only patients with cancer but also longer term survivors. Although the divorce rate has drastically increased in Korea, there is not sufficient research regarding the relationship between changes in marital status and quality of life (QOL) in cancer patients and survivors. Thus, we aimed to examine the relationship between marital status and QOL in such cases. This study was performed using the Community Health Survey of 2008 administered by the Korea Centers for Disease Control and Prevention (N=169,328). We used t-tests and Chi-square tests to compare demographic variables between men and women, and analysis of variance (ANOVA) to compare QOL scores among comparison groups. We also performed a multilevel analysis on the relationship between QOL and marital status while accounting for provincial differences. Decline of EuroQOL five dimensions (EQ-5D) in single patients with cancer was greater than in any other marital status group, but there was no statistically significant decline in survivors of cancer with regard to marital status. In the general population, the decline of EQ-5D was higher among single people than married people. Using the EuroQOL visual analog scale (EQ-VAS), single people had higher values than those of other marital status among both patients with cancer and survivors of cancer. In the general population, EQ-VAS values were higher for single people compared to married people. There may be a significant relationship between marital status and QOL in cancer patients and survivors. Policy interventions to manage patients with cancer who experience a decline in QOL as well as marital problems should be conducted.

The aims are to study personality characteristics of patients with memory complaints and to assess the presence of objective (OMI) versus subjective (SMI) memory impairment, the affective status, as well as potential gender differences. The patients were assessed by means of a neuropsychiatric examination and a neuropsychological test-battery. The Swedish version of the revised NEO Personality Inventory (NEO PI-R) and the Hospital Anxiety and Depression Scale (HADS) were used. The 57 patients (38 women, 19 men, mean age 56.9) differed from the Swedish normative group in three of the five personality factors: neuroticism, extraversion and agreeableness. This was mainly because of the scores of the female patients. Approximately half of the patients had OMI. No differences regarding personality factors or affective status were found between OMI and SMI patients. The female patients scored significantly higher than the male patients on symptoms of anxiety and depression. Neuroticism and symptoms of depression interacted with memory performance and gender. Our findings demonstrate the importance of applying an objective assessment of memory functions and a gender perspective when studying patients with memory complaints.

There is a need for more knowledge about how survivors of childhood cancer perceive their lives and what influence current health status has on their quality of life. The purpose was to describe this among a group of long-term survivors and among a comparison group. Telephone interviews were performed with a cohort of 246 long-term survivors and 296 randomly selected from the general population using the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW). The participants nominated the areas they considered to be most important in life and rated the current status of each area on a seven-point category scale. An overall individual index score was calculated as a measure of quality of life. Self-reported health status was assessed using the Short Form Health Survey (SF-36). Long-term survivors rated their overall quality of life and self-reported health status almost in parity with the comparison group. In both groups, family life, relations to other people, work and career, interests and leisure activities were the areas most frequently reported to influence quality of life. The survivors only differed from the comparison group on one of eight SF-36 scales reflecting problems with daily activities owing to physical health. Health status was not shown to have a major impact on overall quality of life, indicating that health and quality of life should be evaluated distinctively as different constructs. This should be taken in consideration in clinical care of children with childhood cancer and long-term survivors. (c) 2010 Wiley-Liss, Inc.

The consequences of combined undernourishment and decreased physical performance in older adults are debilitating and increases cost of care. To date, the information regarding the association between nutritional status and physical performance does not provide a complete picture. Most studies used limited or self-reported measures to evaluate physical performance. The objective of this study was to examine the correlation between nutritional status and comprehensive physical performance measures among undernourished older adults who reside in residential institutions. Forty-seven older adults (26 males, 21 females) aged ≥ 60 (69.23 ± 8.63) years who were identified as undernourished from two residential institutions participated in this study. A battery of physical performance tests (10 m gait speed test, dominant hand grip strength test, timed five-repetition sit-to-stand test, ten step test, arm curl test, scratch test, and respiratory muscle strength test), biochemical profiles (serum albumin, hemoglobin, serum ferritin, and prealbumin levels), and falls risk using the short-form Physiological Profile Approach were performed. The Functional Ability Questionnaire and Geriatric Depression Scale were also administered. The results demonstrated that generally older adults with undernourishment scored poorly on the physical performance tests, had depression, and a high risk of falls. Biochemical results demonstrated that 10.9% of the participants were anemic, 63% had hypoalbuminemia (<3.5 g/dL), and 21.7% were at risk of protein energy malnutrition with prealbumin level (100-170 mg/L). A significant correlation (P<0.05) was demonstrated between hand grip strength and ferritin, between self-reported mobility dependence and prealbumin levels, and between self-reported mobility tiredness and body mass index. These results confirm that older adults with undernutrition have poor physical function, higher falls risk, and depression. Clinically, overall health that includes nutritional status, physical function, and depression level should be taken into consideration in the assessment and treatment of older adults residing at residential institutions.

Balance performance is considered as an indicator of functional status in the elderly, a large scale population screening and evaluation in the community context followed by proper interventions would be of great significance at public health level. However, there has been no suitable balance testing scale available for large scale studies in the unique community context of urban China. A balance scale named X16 balance testing scale was developed, which was composed of 3 domains and 16 items. A total of 1985 functionally independent and active community-dwelling elderly adults' balance abilities were tested using the X16 scale. The internal consistency, split-half reliability, content validity, construct validity, discriminant validity of X16 balance testing scale were evaluated. Factor analysis was performed to identify alternative factor structure. The Eigenvalues of factors 1, 2, and 3 were 8.53, 1.79, and 1.21, respectively, and their cumulative contribution to the total variance reached 72.0%. These 3 factors mainly represented domains static balance, postural stability, and dynamic balance. The Cronbach alpha coefficient for the scale was 0.933. The Spearman correlation coefficients between items and its corresponding domains were ranged from 0.538 to 0.964. The correlation coefficients between each item and its corresponding domain were higher than the coefficients between this item and other domains. With the increase of age, the scores of balance performance, domains static balance, postural stability, and dynamic balance in the elderly declined gradually (P < 0.001). With the increase of age, the proportion of the elderly with intact balance performance decreased gradually (P < 0.001). The reliability and validity of the X16 balance testing scale is both adequate and acceptable. Due to its simple and quick use features, it is practical to be used repeatedly and routinely especially in community setting and on large scale screening.

OBJECTIVE We investigated the psychometric properties of the Flinn Performance Screening Tool (FPST) for people referred with symptoms of carpal tunnel syndrome (CTS). METHOD An occupational therapist collected data from 46 participants who completed the Functional Status Scale (FSS) and FPST after the participants’ nerve conduction velocity study to test convergent and contrasted-group validity. RESULTS Seventy-four percent of the participants had abnormal nerve conduction studies. Cronbach’s α coefficients for subscale and total scores of the FPST ranged from .96 to .98. Intrarater reliability for six shared items of the FSS and the FPST was supported by high agreement (71%) and a fair κ statistic (.36). Strong to moderate positive relationships were found between the FSS and FPST scores. Functional status differed significantly among severe, mild, and negative CTS severity groups. CONCLUSION The FPST shows adequate psychometric properties as a client-centered screening tool for occupational performance of people referred for symptoms of CTS. PMID:22549598

Greater female autonomy is mirrored through better performance in the major demographic and social indicators. This study attempts to capture the effect of religion on the status of women considering 'Greater Bengal'. There is much evidence suggesting that when cultural factors are constant, religion does not have a significant effect on any demographic issue. In this paper, the validity of this proposition is examined using two datasets, namely NFHS II (98-99) and BDHS 2000. It is clear from the analyses that not only region but also religion has a distinct effect on the status of women. In West Bengal, the religious gap for all the indicators considered is pretty high, whereas in Bangladesh the gap is not that wide. A state-level population policy is needed in West Bengal to act as a social leveller.

To examine the measurement properties of and comparability between the English and Chinese versions of the five-level EuroQoL Group's five-dimension questionnaire (EQ-5D) in breast cancer patients in Singapore. This is an observational study of 269 patients. Known-group validity and responsiveness of the EQ-5D utility index and visual analog scale (VAS) were assessed in relation to various clinical characteristics and longitudinal change in performance status, respectively. Convergent and divergent validity was examined by correlation coefficients between the EQ-5D and a breast cancer-specific instrument. Test-retest reliability was evaluated. The two language versions were compared by multiple regression analyses. For both English and Chinese versions, the EQ-5D utility index and VAS demonstrated known-group validity and convergent and divergent validity, and presented sufficient test-retest reliability (intraclass correlation = 0.72 to 0.83). The English version was responsive to changes in performance status. The Chinese version was responsive to decline in performance status, but there was no conclusive evidence about its responsiveness to improvement in performance status. In the comparison analyses of the utility index and VAS between the two language versions, borderline results were obtained, and equivalence cannot be definitely confirmed. The five-level EQ-5D is valid, responsive, and reliable in assessing health outcome of breast cancer patients. The English and Chinese versions provide comparable measurement results.

The purpose of our approach was to take into account the nested spatial scales driving stream functioning in the description of pressures/ecological status links by analysing the results of a hierarchical model. The development of this model has allowed us to answer the following questions: Does the consideration of the indirect links between anthropogenic pressures and stream ecological status modify the hierarchy of pressure types impacting benthic invertebrates? Do the different nested scales play different roles in the anthropogenic pressures/ecological status relationship? Does this model lead to better understanding of the specific role of hydromorphology in the evaluation of stream ecological status? To achieve that goal, we used the Partial Least Square (PLS) path modelling method to develop a structural model linking variables describing (i) land use and hydromorphological alterations at the watershed scale, (ii) hydromorphological alterations at the reach scale, (iii) nutrients-organic matter contamination levels at the site scale, and (iv) substrate characteristics at the sampling site scale, to explain variation in values of a macroinvertebrate-based multimetric index: the French I 2 M 2 . We have highlighted the importance of land use effects exerted on both hydromorphological and chemical characteristics of streams observed at finer scales and their subsequent indirect impact on stream ecological status. Hydromorphological alterations have an effect on the substrate mosaic structure and on the concentrations of nutrients and organic matter at site scale. This result implies that stream hydromorphology can have a major indirect effect on macroinvertebrate assemblages and that the hierarchy of impacts of anthropogenic pressures on stream ecological status generally described in the literature - often determining strategic restoration priorities - has to be re-examined. Finally, the effects of nutrients and organic matter on macroinvertebrate assemblages are lower than expected when all the indirect effects of land use and hydromorphological alterations are taken into account.

OBJECTIVE. The goal of this study was to develop unbiased risk-assessment models to be used for paying health plans on the basis of enrollee health status and use propensity. We explored the risk structure of adult employed HMO members using self-reported morbidities, functional status, perceived health status, and demographic characteristics. DATA SOURCES/STUDY SETTING. Data were collected on a random sample of members of a large, federally qualified, prepaid group practice, hospital-based HMO located in the Pacific Northwest. STUDY DESIGN. Multivariate linear nonparametric techniques were used to estimate risk weights on demographic, morbidity, and health status factors at the individual level. The dependent variable was annual real total health plan expense for covered services for the year following the survey. Repeated random split-sample validation techniques minimized outlier influences and avoided inappropriate distributional assumptions required by parametric techniques. DATA COLLECTION/EXTRACTION METHODS. A mail questionnaire containing an abbreviated medical history and the RAND-36 Health Survey was administered to a 5 percent sample of adult subscribers and their spouses in 1990 and 1991, with an overall 44 percent response rate. Utilization data were extracted from HMO automated information systems. Annual expenses were computed by weighting all utilization elements by standard unit costs for the HMO. PRINCIPAL FINDINGS. Prevalence of such major chronic diseases as heart disease, diabetes, depression, and asthma improve prediction of future medical expense; functional health status and morbidities are each better than simple demographic factors alone; functional and perceived health status as well as demographic characteristics and diagnoses together yield the best prediction performance and reduce opportunities for selection bias. We also found evidence of important interaction effects between functional/perceived health status scales and disease classes. CONCLUSIONS. Self-reported morbidities and functional health status are useful risk measures for adults. Risk-assessment research should focus on combining clinical information with social survey techniques to capitalize on the strengths of both approaches. Disease-specific functional health status scales should be developed and tested to capture the most information for prediction. PMID:8698586

We verified the reliability and validity of the Korean version of the Minneapolis-Manchester Quality of Life Instrument-Adolescent Form (KMMQL-AF) among Korean childhood cancer survivors. A total of 107 childhood cancer patients undergoing cancer treatment and 98 childhood cancer survivors who completed cancer treatment were recruited. To assess the internal structure of the KMMQL-AF, we performed multi-trait scaling analyses and exploratory factor analysis. Additionally, we compared each domains of the KMMQL-AF with those of the Karnofsky Performance Status Scale and the Revised Children's Manifest Anxiety Scale (RCMAS). Internal consistency of the KMMQL-AF was sufficient (Cronbach's alpha: 0.78-0.92). In multi-trait scaling analyses, the KMMQL-AF showed sufficient construct validity. The "physical functioning" domain showed moderate correlation with Karnofsky scores and the "psychological functioning" domain showed moderate-to-high correlation with the RCMAS. The KMMQL-AF discriminated between subgroups of different adolescent cancer survivors depending on treatment completion. The KMMQL-AF is a sufficiently reliable and valid instrument for measuring quality of life among Korean childhood cancer survivors.

Status epilepticus (SE) is a neurological emergency, characterized by high short-term morbidity and mortality. We evaluated and compared two scores that have been developed to evaluate status epilepticus prognosis: STESS (Status Epilepticus Severity Score) and EMSE (Epidemiology based Mortality score in Status Epilepticus). A prospective observational study was performed on consecutive patients with SE admitted between September 2013 and August 2015. Demographics, clinical variables, STESS-3 and -4, and EMSE-64 scores were calculated for each patient at baseline. SE drug response, 30-day mortality and morbidity were the outcomes measure. 162 episodes of SE were observed: 69% had a STESS ≥3; 34% had a STESS ≥4; 51% patients had an EMSE ≥64. The 30-days mortality was 31.5%: EMSE-64 showed greater negative predictive value (NPV) (97.5%), positive predictive value (PPV) (59.8%) and accuracy in the prediction of death than STESS-3 and STESS-4 (p<0.001). At 30 days, the clinical condition had deteriorated in 59% of the cases: EMSE-64 showed greater NPV (71.3%), PPV (87.8%) and accuracy than STESS-3 and STESS-4 (p<0.001) in the prediction of this outcome. In 23% of all cases, status epilepticus proved refractory to non-anaesthetic treatment. All three scales showed a high NPV (EMSE-64: 87.3%; STESS-4: 89.4%; STESS-3: 87.5%) but a low PPV (EMSE-64: 40.9%; STESS-4: 52.9%; STESS-3: 32%) for the prediction of refractoriness to first and second line drugs. This means that accuracy for the prediction of refractoriness was equally poor for all scales. EMSE-64 appears superior to STESS-3 and STESS-4 in the prediction of 30-days mortality and morbidity. All scales showed poor accuracy in the prediction of response to first and second line antiepileptic drugs. At present, there are no reliable scores capable of predicting treatment responsiveness.

Due to the rising standard of living environment and advances in public health and medical care in China, it has been a tendency in recent years that health-related quality of life (HRQoL) has been increasingly acknowledged in community health management. However, large-scale population-based study on evaluating HQRoL in northeast of China was not conducted. This article aims to investigate the HRQoL in community residents in Northeast China and explore the associated factors. Stratified multiple-stage sampling method was used in the cross-sectional survey to investigate HRQoL of community residents in northeast of China. Univariate analysis and multiple linear regressions were used to analyze the factors associated to HRQoL of the community residents. The results were confirmed that HRQoL in general population was well performed for the first time in northeast of China in a large scale population. Community residents had better mental health than physical health. The factors influencing HRQoL included gender, age, educational level, marital status, ethnic group, chronic disease status, having breakfast frequency weekly and sleep quality. However, drinking and smoking habits did not affect residents' HRQoL. In this study, the result of the large-scale survey was satisfactory in northeast of China, providing HRQoL status of community residents. Policies on specific health management in community public health would emphasize on lifestyle behaviors especially eating habits in order to improving HRQoL.

The aim of this study was to evaluate the effect of breast cancer fatalism and other factors on breast cancer awareness among Turkish women. This cross-sectional and comparative descriptive study was conducted with 894 women. Data were collected by Personal Information Form, Powe Fatalism Inventory and Champion's Health Belief Model Scale. Seriousness, health motivation, BSE benefits and BSE self-efficacy perceptions of the women were moderate, and susceptibility and BSE barriers perceptions were low. It was determined that awareness of breast cancer of the women was affected by breast cancer fatalism, age, education level, employment status, marital status, family type, economic status, social assurance, menopause status, family history of cancer, family history of breast cancer, knowledge on BSE, source of information on BSE, performing of BSE, frequency of BSE performing, having a problem with breast, having a breast examination in hospital, feeling during breast examination by healthcare professional, sex of healthcare professional for breast examination and their health beliefs (p < .05). The results suggested that awareness of breast cancer of the women was affected by breast cancer fatalism. In providing breast cancer early diagnosis behaviors, it is recommended to evaluate fatalism perceptions and health beliefs of the women and to arrange educational programs for this purpose.

Evaluation of the ecological status of river sites in Canada is supported by building models using the reference condition approach. However, geography, data scarcity and inter-operability constraints have frustrated attempts to monitor national-scale status and trends. This issue is particularly true in Atlantic Canada, where no ecological assessment system is currently available. Here, we present a reference condition model based on the River Invertebrate Prediction and Classification System approach with regional-scale applicability. To achieve this, we used biological monitoring data collected from wadeable streams across Atlantic Canada together with freely available, nationally consistent geographic information system (GIS) environmental data layers. For the first time, we demonstrated that it is possible to use data generated from different studies, even when collected using different sampling methods, to generate a robust predictive model. This model was successfully generated and tested using GIS-based rather than local habitat variables and showed improved performance when compared to a null model. In addition, ecological quality ratio data derived from the model responded to observed stressors in a test dataset. Implications for future large-scale implementation of river biomonitoring using a standardised approach with global application are presented.

The aim of this research was to explore quality of life (QOL) and acceptance of disability and social support of colostomy patients as well as the relationship between these factors. A descriptive, correlational study was conducted using four scales: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and European Organization for Research and Treatment of Cancer Colorectal Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-CR38) scales, the Acceptance of Disability Scale (ADS), and the Social Relational Quality Scale (SRQS). A convenience sample of 111 colostomy patients from four hospitals in Guangzhou who underwent colostomy operation at least one month prior to the study and who visited the stoma clinic or association from August 2011 to February 2012 was evaluated for inclusion in the study. All statistical analyses were performed using SPSS 17.0 software (SPSS Inc., Chicago, IL, USA). The patients' general health status was better than the reference level recommended by European Organization for Research and Treatment of Cancer, and the overall ADS score was average. The SRQS score was similar to that found in a Hong Kong study. The general health status and dimensions of QOL were significantly correlated with ADS and all of its dimensions (P < 0.05). The general health status and dimensions of QOL were also significantly correlated with SRQS and all of its dimensions (P < 0.05). QOL, acceptance of disability, and social relational quality of colostomy patients were closely related. Our results emphasize that patients should work to form rational values and close bonds with families and friends to achieve a better QOL.

When assessments are primarily used to measure change over time, it is important to evaluate items according to their sensitivity to change, specifically. Items that demonstrate good sensitivity to between-person differences at baseline may not show good sensitivity to change over time, and vice versa. In this study, we applied a longitudinal factor model of change to a widely used cognitive test designed to assess global cognitive status in dementia, and contrasted the relative sensitivity of items to change. Statistically nested models were estimated introducing distinct latent factors related to initial status differences between test-takers and within-person latent change across successive time points of measurement. Models were estimated using all available longitudinal item-level data from the Alzheimer's Disease Assessment Scale-Cognitive subscale, including participants representing the full-spectrum of disease status who were enrolled in the multisite Alzheimer's Disease Neuroimaging Initiative. Five of the 13 Alzheimer's Disease Assessment Scale-Cognitive items demonstrated noticeably higher loadings with respect to sensitivity to change. Attending to performance change on only these 5 items yielded a clearer picture of cognitive decline more consistent with theoretical expectations in comparison to the full 13-item scale. Items that show good psychometric properties in cross-sectional studies are not necessarily the best items at measuring change over time, such as cognitive decline. Applications of the methodological approach described and illustrated in this study can advance our understanding regarding the types of items that best detect fine-grained early pathological changes in cognition.

The MCFC technology has been identified by the DOE as a promising product for commercialization. Development of the MCFC technology supports the National Energy Strategy. Review of the status of the MCFC technology indicates that the MCFC technology developers are making rapid and significant progress. Manufacturing facility development and extensive testing is occurring. Improvements in performance (power density), lower costs, improved packaging, and scale up to full height are planned. MCFC developers need to continue to be responsive to end-users in potential markets. It will be market demands for the correct product definition which will ultimately determine the character of MCFC power plants. There is a need for continued MCFC product improvement and multiple product development tests.

The purpose of this study is to describe the functional status of survivors from extracorporeal cardiopulmonary resuscitation instituted during in-hospital cardiac arrest using the Functional Status Scale. We aimed to determine risk factors leading to the development of new morbidity and unfavorable functional outcomes. This was a single-center retrospective chart review abstracting patient characteristics/demographic data, duration of cardiopulmonary resuscitation, duration of extracorporeal membrane oxygenation support, as well as maximum lactate levels within 2 hours before and after extracorporeal cardiopulmonary resuscitation. Cardiac arrest was defined as the administration of chest compressions for a nonperfusing cardiac rhythm. Extracorporeal cardiopulmonary resuscitation was defined by instituting extracorporeal membrane oxygenation during active chest compressions. Functional Status Scale scores were calculated at admission and on hospital discharge for patients who survived. Patients admitted in the pediatric cardiac ICU at C.S. Mott Children's Hospital from January 1, 2005, to December 31, 2015. Children less than 18 years who underwent extracorporeal cardiopulmonary resuscitation. Not applicable. Of 608 extracorporeal membrane oxygenation events during the study period, 80 were extracorporeal cardiopulmonary resuscitation (14%). There were 40 female patients (50%). Median age was 40 days (interquartile range, 9-342 d). Survival to hospital discharge was 48% (38/80). Median Functional Status Scale score at admission was 6 (interquartile range, 6-6) and at hospital discharge 9 (interquartile range, 8-11). Out of 38 survivors, 19 (50%) had a change of Functional Status Scale score greater than or equal to 3, that is consistent with new morbidity, and 26 (68%) had favorable functional outcomes with a change in Functional Status Scale score of less than 5. This is the first extracorporeal cardiopulmonary resuscitation report to examine changes in Functional Status Scale from admission (baseline) to discharge as a measure of overall functional outcome. Half of surviving patients (19/38) had new morbidity, while 68% (26/38) had favorable outcomes. Lactate levels, duration of cardiopulmonary resuscitation, and duration of extracorporeal membrane oxygenation were not found to be risk factors for the development of new morbidity and poor functional outcomes. Functional Status Scale may be used as a metric to monitor improvement of extracorporeal cardiopulmonary resuscitation outcomes and help guide research initiatives to decrease morbidity in this patient population.

Multitemporal L- and C-Band Synthetic Aperture Radar To Highlight Differences in Water Status Among Boreal Forest and Wetland Systems in the Yukon Flats, Interior Alaska

Tracking landscape-scale water status in high-latitude boreal systems is indispensible to understanding the fate of stored and sequestered carbon in a climate change scenario. Spaceborne synthetic aperture radar (SAR) imagery provides critical information for water and moisture status in Alaskan boreal environments at the landscape scale. When combined with results from optical sensor analyses, a complementary picture of vegetation, biomass, and water status emerges. Whereas L-band SAR showed better inherent capacity to map water status, C-band had much more temporal coverage in this study. Analysis through the use of L- and C-band SARs combined with Landsat Enhanced Thematic Mapper Plus (ETM+) enables landscape stratification by vegetation and by seasonal and interannual hydrology. Resultant classifications are highly relevant to biogeochemistry at the landscape scale. These results enhance our understanding of ecosystem processes relevant to carbon balance and may be scaled up to inform regional carbon flux estimates and better parameterize general circulation models (GCMs).

This study examined associations between anxiety and work-related outcomes in an anxiety disorders clinic population, examining both pretreatment links and the impact of anxiety change over 12 weeks of treatment on work outcomes. Four validated instruments were used to also allow examination of their psychometric properties, with the goal of improving measurement of work-related quality of life in this population. Newly enrolled adult patients seeking treatment in a university-based anxiety clinic were administered four work performance measures: Work Limitations Questionnaire (WLQ), Work Productivity and Activity Impairment Questionnaire (WPAI), Endicott Work Productivity Scale (EWPS), and Functional Status Questionnaire Work Performance Scale (WPS). Anxiety severity was determined using the Beck Anxiety Inventory (BAI). The Clinical Global Impressions, Global Improvement Scale (CGI-I) was completed by patients to evaluate symptom change at a 12-week follow-up. Two severity groups (minimal/mild vs. moderate/severe, based on baseline BAI score) were compared to each other on work measures. Eighty-one patients provided complete baseline data. Anxiety severity groups did not differ in job type, time on job, job satisfaction, or job choice. Patients with greater anxiety generally showed lower work performance on all instruments. Job advancement was impaired for the moderate/severe group. The multi-item performance scales demonstrated better validity and internal consistency. The WLQ and the WPAI detected change with symptom improvement. Level of work performance was generally associated with severity of anxiety. Of the instruments tested, the WLQ and the WPAI questionnaire demonstrated acceptable validity and internal reliability.

Estimating the effects of land use at different scales on high ecological status in Irish rivers.

High ecological status at river sites is an indicator of minimal disturbance from anthropogenic activities and the presence of ecologically important species and communities. However, a lack of clarity on what factors cause sites to lose high ecological status is limiting the ability to maintain the quality of these sites. Examination of ecological status records at 508 high status river sites throughout the Republic of Ireland revealed that 337 had fallen below high status at some point between 2001 and 2012 due to changes in invertebrate communities. A geographical information system was used to characterise land use and environmental variables in the catchment, riparian and reach areas upstream of the sites. The relationships between these variables at the three spatial scales and whether or not river sites had maintained high ecological status were then estimated by multiple logistic regression and propensity modelling. The results indicated that grassland at either catchment or riparian scales had a greater negative impact on high ecological status than at the reach scale. This effect appeared to be strongest for upland, steeply sloping rivers that are subject to high rainfall, possibly due to the presence of sensitive biota and/or a greater potential for erosion. These results highlighted the need for better management of grassland upstream of the high status sites, with a focus on river alterations and critical source areas of nutrients, sediments and pesticides that are hydrologically connected to the river. Sustainable management practices and land use planning in those areas will need to be considered carefully if the aim of maintaining high ecological status at river sites is to be achieved.

The objective of this research is to analyze the nutritional status and household food security of a sample of healthy pregnant women who attend to external medicine service at Concepcion Palacios Maternity located in Caracas, Venezuela, and identify variables, which could predict the nutritional status of the evaluated group. This cross sectional, descriptive, comparative study evaluates a sample of 89 pregnant women, between 14 and 44 years of age. Economical, social, demographic and alimentary consumption variables and nutritional conditions were studied. On the way, anthropometrics like weight, height, and middle-arm circumference and Household food security scale were obtained. In order to perform the descriptive statistic, bivariate, and multiple linear regression analysis required during the investigation, the software SPSS, version 12, was used. The predictive variables considered for the evaluation of the actual nutritional status in pregnant women were: right middle-arm circumference, household food security level and the supplementation with vitamins and/or minerals. These variables explain 78.2% of the actual nutritional status variation in this sample. Therefore, this investigation highlights the importance of the research on simple variables, as a good prediction of the actual nutritional status in pregnant women, with acceptable precision values and without requiring high-trained personnel to perform it. Under these findings, is very important the study of more predictive variables to evaluate the nutritional and alimentary conditions, with practical and easy mechanisms that can be applied by non-technical personnel. It is recommended to go deep into the study of methods, which evaluate the nutrition in an easy and practical way, applied by non-technical personnel, besides continuing the validation process of the variable combinations determined as predictive of the nutritional status.

The SCORE scale predicts the 10-year risk of fatal atherosclerotic cardiovascular disease (CVD), based on conventional risk factors. The high-risk version of SCORE is recommended for Central and Eastern Europe and former Soviet Union (CEE/FSU), due to high CVD mortality rates in these countries. Given the pronounced social gradient in cardiovascular mortality in the region, it is important to consider social factors in the CVD risk prediction. We investigated whether adding education and marital status to SCORE benefits its prognostic performance in two sets of population-based CEE/FSU cohorts. The WHO MONICA (MONItoring of trends and determinants in CArdiovascular disease) cohorts from the Czech Republic, Poland (Warsaw and Tarnobrzeg), Lithuania (Kaunas), and Russia (Novosibirsk) were followed from the mid-1980s (577 atherosclerotic CVD deaths among 14,969 participants with non-missing data). The HAPIEE (Health, Alcohol, and Psychosocial factors In Eastern Europe) study follows Czech, Polish (Krakow), and Russian (Novosibirsk) cohorts from 2002-05 (395 atherosclerotic CVD deaths in 19,900 individuals with non-missing data). In MONICA and HAPIEE, the high-risk SCORE ≥5% at baseline strongly and significantly predicted fatal CVD both before and after adjustment for education and marital status. After controlling for SCORE, lower education and non-married status were significantly associated with CVD mortality in some samples. SCORE extension by these additional risk factors only slightly improved indices of calibration and discrimination (integrated discrimination improvement <5% in men and ≤1% in women). Extending SCORE by education and marital status failed to substantially improve its prognostic performance in population-based CEE/FSU cohorts.

To determine the effects of a short-duration, combined (inspiratory and expiratory), progressive resistance respiratory muscle training (RMT) protocol on respiratory muscle strength, fatigue, health-related quality of life, and functional performance in individuals with mild-to-moderate multiple sclerosis (MS). Quasi-experimental before-after trial. University rehabilitation research laboratory. Volunteers with MS (N=21) were divided into 2 groups: RMT (n=11; 9 women, 2 men; mean age ± SD, 50.9 ± 5.7y, mean Expanded Disability Status Scale score ± SD, 3.2 ± 1.9) and a control group that did not train (n=10; 7 women, 3 men; mean age ± SD, 56.2 ± 8.8y, mean Expanded Disability Status Scale score ± SD, 4.4 ± 2.1). Expanded Disability Status Scale scores ranged from 1 to ≤6.5. No patients withdrew from the study. Training was a 5-week combined progressive resistance RMT program, 3d/wk, 30 minutes per session. The primary outcome measures were maximal inspiratory pressure and expiratory pressure and the Modified Fatigue Impact Scale. All subjects completed secondary measures of pulmonary function, the six-minute walk test, the timed stair climb, the Multiple Sclerosis Self-Efficacy Scale, the Medical Outcomes Study 36-Item Short-Form Health Survey, and the Physical Activity Disability Scale. Maximal inspiratory pressure and expiratory pressure (mean ± SD) increased 35% ± 22% (P<.001) and 26% ± 17% (P<.001), respectively, whereas no changes were noted in the control group (12% ± 23% and -4% ± 17%, respectively). RMT improved fatigue (Modified Fatigue Impact Scale, P<.029), with no change or worsening in the control group. No changes were noted in the six-minute walk test, stair climb, Multiple Sclerosis Self-Efficacy Scale, or Physical Activity Disability Scale in the RMT group. The control group had decreases in emotional well-being and general health (Medical Outcomes Study 36-Item Short-Form Health Survey). A short-duration, combined RMT program improved inspiratory and expiratory muscle strength and reduced fatigue in patients with mild to moderate MS.

To make longitudinal comparisons of intelligence quotient (IQ) in children with cochlear implants (CIs) and typical hearing peers from early in development to the school-age period. Children with additional comorbidities and CIs were also evaluated. To estimate the impact of socioeconomic status and oral language on school-age cognitive performance. This longitudinal study evaluated nonverbal IQ in a multicenter, national sample of 147 children with CIs and 75 typically hearing peers. IQ was evaluated at baseline, prior to cochlear implantation, using the Bayley Scales of Infant and Toddler Development and the Leiter International Performance Scale. School-age IQ was assessed using the Wechsler Intelligence Scales for Children. For the current study, only the Perceptual Reasoning and Processing Speed indices were administered. Oral language was evaluated using the Comprehensive Assessment of Spoken Language. Children in the CI group scored within the normal range of intelligence at both time points. However, children with additional comorbidities scored significantly worse on the Processing Speed, but not the Perceptual Reasoning Index. Maternal education and language were significantly related to school-age IQ in both groups. Importantly, language was the strongest predictor of intellectual functioning in both children with CIs and normal hearing. These results suggest that children using cochlear implants perform similarly to hearing peers on measures of intelligence, but those with severe comorbidities are at-risk for cognitive deficits. Despite the strong link between socioeconomic status and intelligence, this association was no longer significant once spoken language performance was accounted for. These results reveal the important contributions that early intervention programs, which emphasize language and parent training, contribute to cognitive functioning in school-age children with CIs. For families from economically disadvantaged backgrounds, who are at-risk for suboptimal outcomes, these early intervention programs are critical to improve overall functioning.

Although corticosteroids are widely used to relieve cancer-related fatigue (CRF), information regarding the factors predicting responses to corticosteroids remains limited. The aim of this study was to identify potential factors predicting responses to corticosteroids for CRF in advanced cancer patients. Inclusion criteria for this multicenter, prospective, observational study were patients who had metastatic or locally advanced cancer and had a fatigue intensity score of 4 or more on a 0-10 Numerical Rating Scale (NRS). Univariate and multivariate analyses were conducted to identify the factors predicting two-point reduction or more in NRS on day 3. Among 179 patients who received corticosteroids, 86 (48%; 95% CI 41%-56%) had a response with two-point reduction or more. Factors that significantly predicted responses were performance status score of 3 or more, Palliative Performance Scale score more than 40, absence of ascites, absence of drowsiness, absence of depression, serum albumin level greater than 3 mg/dL, serum sodium level greater than 135 mEq/L, and baseline NRS score greater than 5. A multivariate analysis showed that the independent factors predicting responses were baseline NRS score greater than 5 (odds ratio [OR] 6.6, 95% CI 2.8-15.4), Palliative Performance Scale score more than 40 (OR 4.4, 95% CI 2.1-9.3), absence of drowsiness (OR 3.4, 95% CI 1.7-6.9), absence of ascites (OR 2.3, 95% CI 1.1-4.7), and absence of pleural effusion (OR 2.2, 95% CI 1.0-5.0). Treatment responses to corticosteroids for CRF may be predicted by baseline symptom intensity, performance status, drowsiness, and severity of fluid retention symptoms. Larger prospective studies are needed to confirm these results. Copyright © 2016 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc. All rights reserved.

Status on an effort to develop Turbine Based Combined Cycle (TBCC) propulsion is described. This propulsion technology can enable reliable and reusable space launch systems. TBCC propulsion offers improved performance and safety over rocket propulsion. The potential to realize aircraft-like operations and reduced maintenance are additional benefits. Among most the critical TBCC enabling technologies are: 1) mode transition from turbine to scramjet propulsion, 2) high Mach turbine engines and 3) TBCC integration. To address these TBCC challenges, the effort is centered on a propulsion mode transition experiment and includes analytical research. The test program, the Combined-Cycle Engine Large Scale Inlet Mode Transition Experiment (CCE LIMX), was conceived to integrate TBCC propulsion with proposed hypersonic vehicles. The goals address: (1) dual inlet operability and performance, (2) mode-transition sequences enabling a switch between turbine and scramjet flow paths, and (3) turbine engine transients during transition. Four test phases are planned from which a database can be used to both validate design and analysis codes and characterize operability and integration issues for TBCC propulsion. In this paper we discuss the research objectives, features of the CCE hardware and test plans, and status of the parametric inlet characterization testing which began in 2011.

Mental health inequalities are an increasingly important global problem. This study examined the association between mental health status and certain socioeconomic indicators (personal social position and the socioeconomic status of the family) in Slovenian 15-year-old adolescents. Data originate from the WHO-Collaborative cross-national 'Health Behavior in School-aged Children' study conducted in Slovenia in 2010 (1,815 secondary school pupils, aged 15). Mental health status was measured by: KIDSCREEN-10, the Strength and Difficulties questionnaire (SDQ), a life satisfaction scale, and one question about feelings of depression. Socioeconomic position was measured by the socioeconomic status of the family (Family Affluence Scale, perceived material welfare, family type, occupational status of parents) and personal social position (number of friends and the type of school). Logistic regression and a multivariate analysis of variance (MANOVA) were performed. Girls had 2.5-times higher odds of suffering feelings of depression (p < 0.001), 1.5-times higher odds of low life satisfaction (p = 0.008), and a greater chance of a lower quality of life and a higher SDQ score than boys (p = 0.001). The adolescents who perceived their family's material welfare as worse had 4-times higher odds (p < 0.001) of a low life satisfaction, a greater chance of a low quality of life, and a higher SDQ score than those who perceived it as better (p < 0.001). Adolescents with no friends had lower KIDSCREEN-10 and higher SDQ scores than those who had more than three friends. Despite the fact that Slovenia is among the EU members with the lowest rates of social inequalities, it was found that adolescents with a lower socioeconomic position have poorer mental health than those with a higher socioeconomic position. Because of the financial crisis, we can expect an increase in social inequalities and a greater impact on adolescents' mental health status in Slovenia in the future.

Although diarrhea is a preventable disease, it remains the second leading cause of death (after pneumonia) among children aged under five years worldwide. The World Health Organization (WHO) scale, the Gorelick scale, and the Clinical Dehydration Scale (CDS) were created to estimate dehydration status using clinical signs. The purpose of this study is to determine whether these clinical scales can accurately assess dehydration status of children in a developing country of Kosovo. Children aged 1 month to 5 years with a history of acute diarrhea were enrolled in the study. After recording the data about the patients historical features the treating physician recorded the physical examination findings consistent with each clinical score. Receiver operating characteristic (ROC) curves were constructed to evaluate the performance of the three scales, compared to the gold standard, percent weight change with rehydration. Sensitivity, specificity and likelihood ratios were calculated using the best cut-off points of the ROC curves. We enrolled 230 children, and 200 children met eligibility criteria. The WHO scale for predicting significant dehydration (≥5 percent weight change) had an area under the curve (AUC) of 0.71 (95% : CI= 0.65-0.77). The Gorelick scales 4- and 10-point for predicting significant dehydration, had an area under the curve of 0.71 (95% : CI=0.63- 0.78) and 0.74 (95% : CI= 0.68-0.81) respectively. Only the CDS for predicting the significant dehydration above ≥6% percent weight change, did not have an area under the curve statistically different from the reference line with an AUC of 0.54 (95% CI = 0.45- 0.63). The WHO dehydration scale and Gorelick scales were fair predictors of dehydration in children with diarrhea. Only the Clinical Dehydration Scale was found not to be a helpful predictor of dehydration in our study cohort.

Background. This report describes the levels of physical function in U.S. Chinese older adults utilizing self-reported and performance-based measures, and examines the association between sociodemographic characteristics and physical function. Methods. The Population Study of Chinese Elderly in Chicago enrolled an epidemiological cohort of 3,159 community-dwelling Chinese older adults aged 60 and older. We collected self-reported physical function using Katz activities of daily living and Lawton instrumental activities of daily living items, the Index of Mobility scale, and the Index of Basic Physical Activities scale. Participants were also asked to perform tasks in chair stand, tandem stand, and timed walk. We computed Pearson and Spearman correlation coefficients to examine the correlation between sociodemographic and physical function variables. Results. A total of 7.8% of study participants experienced activities of daily living impairment, and 50.2% experienced instrumental activities of daily living impairment. With respect to physical performance testing, 11.4% of the participants were not able to complete chair stand for five times, 8.5% of the participants were unable to do chair stands at all. Older age, female gender, lower education level, being unmarried, living with fewer people in the same household, having fewer children, living fewer years in the United States, living fewer years in the community, and worsening health status were significantly correlated with lower levels of physical function. Conclusions. Utilizing self-reported and performance-based measures of physical function in a large population-based study of U.S. Chinese older adults, our findings expand current understanding of minority older adults’ functional status.

Biomechanical characterization of human performance with respect to fatigue and fitness is relevant in many settings, however is usually limited to either fully qualitative assessments or invasive methods which require a significant experimental setup consisting of numerous sensors, force plates, and motion detectors. Qualitative assessments are difficult to standardize due to their intrinsic subjective nature, on the other hand, invasive methods provide reliable metrics but are not feasible for large scale applications. Presented here is a dynamical toolset for detecting performance groups using a non-invasive system based on the Microsoft Kinect motion capture sensor, and a case study of 37 cancer patients performing two clinically monitored tasks before and after therapy regimens. Dynamical features are extracted from the motion time series data and evaluated based on their ability to i) cluster patients into coherent fitness groups using unsupervised learning algorithms and to ii) predict Eastern Cooperative Oncology Group performance status via supervised learning. The unsupervised patient clustering is comparable to clustering based on physician assigned Eastern Cooperative Oncology Group status in that they both have similar concordance with change in weight before and after therapy as well as unexpected hospitalizations throughout the study. The extracted dynamical features can predict physician, coordinator, and patient Eastern Cooperative Oncology Group status with an accuracy of approximately 80%. The non-invasive Microsoft Kinect sensor and the proposed dynamical toolset comprised of data preprocessing, feature extraction, dimensionality reduction, and machine learning offers a low-cost and general method for performance segregation and can complement existing qualitative clinical assessments.

What evolutionary function does self-regard serve? Hierometer theory, introduced here, provides one answer: it helps individuals navigate status hierarchies, which feature zero-sum contests that can be lost as well as won. In particular, self-regard tracks social status to regulate behavioral assertiveness, augmenting or diminishing it to optimize performance in such contests. Hierometer theory also offers a conceptual counterpoint that helps resolve ambiguities in sociometer theory, which offers a complementary account of self-regard’s evolutionary function. In two large-scale cross-sectional studies, we operationalized theoretically relevant variables at three distinct levels of analysis, namely, social (relations: status, inclusion), psychological (self-regard: self-esteem, narcissism), and behavioral (strategy: assertiveness, affiliativeness). Correlational and mediational analyses consistently supported hierometer theory, but offered only mixed support for sociometer theory, including when controlling for confounding constructs (anxiety, depression). We interpret our results in terms of a broader agency-communion framework. PMID:27065896

Neurological and cognitive aspects of adolescent psychotic disorders are understudied. The authors assessed 19 adolescents with psychosis and 16 healthy comparison subjects using the Neurological Evaluation Scale (NES) and age-appropriate Wechsler intelligence quotient (IQ) scales. NES scores were highest and IQ scores were lowest among subjects with psychosis. Subjects with psychosis did not demonstrate age-related decreases in NES score. The combination of NES and IQ scores predicted both the presence of psychosis and psychiatric diagnosis. There were no relationships between medication status and either NES or IQ scores. These results support a broadly conceived neurodevelopmental formulation of adolescent psychotic disorders.

To conduct a systematic review of the literature on prospective cohort studies examining mortality risk according to frailty defined by FRAIL scale, and to perform a meta-analysis to synthesize the pooled risk estimates. Systematic review and meta-analysis. Embase, Scopus, MEDLINE, CINAHL, and PsycINFO were systematically searched in March 2018. References of included studies were reviewed and a forward citation tracking was performed on relevant review papers for additional studies. Additional data necessary for a meta-analysis were requested from corresponding authors. Community-dwelling middle-aged and older adults. Mortality risk due to frailty as defined by the FRAIL scale. After removing duplicates, there are 81 citations for title, abstract, and full-text screening. Eight studies were included in this review. Four studies calculated the area under the receiver operating characteristic curve, which ranged from 0.54 to 0.70. A random-effects meta-analysis was conducted on 3 studies that provided adjusted hazard ratios (HRs) of mortality risk according to 3 frailty groups (robust, prefrail, and frail) defined by FRAIL scale. Both frailty and prefrailty were significantly associated with higher mortality risk than robustness [pooled HR = 3.53, 95% confidence interval (CI) = 1.66-7.49, P = .001; pooled HR = 1.75, 95% CI = 1.14-2.70, P = .01, respectively]. No evidence of publication bias was observed. This study demonstrated that FRAIL scale is a tool that can effectively identify frailty/prefrailty status, as well as quantify frailty status in a graded manner in relation to mortality risk. Although its feasibility is of note, not many studies are yet using this relatively new tool. More studies are warranted regarding mortality and other health outcomes.

Objective To characterize the relationship between dispersion-based intra-individual variability (IIVd) in neuropsychological test performance and brain volume among HIV seropositive and seronegative men and to determine the effects of cardiovascular risk and HIV infection on this relationship. Methods Magnetic Resonance Imaging (MRI) was used to acquire high-resolution neuroanatomic data from 147 men age 50 and over, including 80 HIV seropositive (HIV+) and 67 seronegative controls (HIV−) in this cross-sectional cohort study. Voxel Based Morphometry was used to derive volumetric measurements at the level of the individual voxel. These brain structure maps were analyzed using Statistical Parametric Mapping (SPM2). IIVd was measured by computing intra-individual standard deviations (ISD’s) from the standardized performance scores of five neuropsychological tests: Wechsler Memory Scale-III Visual Reproduction I and II, Logical Memory I and II, Wechsler Adult Intelligence Scale-III Letter Number Sequencing. Results Total gray matter (GM) volume was inversely associated with IIVd. Among all subjects, IIVd -related GM atrophy was observed primarily in: 1) the inferior frontal gyrus bilaterally, the left inferior temporal gyrus extending to the supramarginal gyrus, spanning the lateral sulcus; 2) the right superior parietal lobule and intraparietal sulcus; and, 3) dorsal/ventral regions of the posterior section of the transverse temporal gyrus. HIV status, biological, and cardiovascular disease (CVD) variables were not linked to IIVd -related GM atrophy. Conclusions IIVd in neuropsychological test performance may be a sensitive marker of cortical integrity in older adults, regardless of HIV infection status or CVD risk factors, and degree of intra-individual variability links with volume loss in specific cortical regions; independent of mean-level performance on neuropsychological tests.

Deficiencies of vitamin A, iron, and iodine are major public health concerns in many low- and middle-income countries, but information on their status in populations is often lacking due to high costs and logistical challenges associated with assessing micronutrient status. Accurate, user-friendly, and low-cost analytical tools are needed to allow large-scale population surveys on micronutrient status. We present the expansion of a 7-plex protein microarray tool for the simultaneous measurement of up to seven biomarkers with relevance to the assessment of the key micronutrients iron, iodine, and vitamin A, and inflammation and malaria biomarkers: α-1-acid glycoprotein, C-reactive protein, ferritin, retinol binding protein 4, soluble transferrin receptor, thyroglobulin, and histidine-rich protein II. Assay performance was assessed using international reference standards and then verified by comparing the multiplexed and conventional immunoassay results on a training panel of plasma samples collected from US adults. These data were used to assign nominal concentrations to the calibrators of the assay to further improve performance which was then assessed by interrogating plasma samples from a cohort of pregnant women from Niger. The correlation between assays for each biomarker measured from this cohort was typically good, with the exception of thyroglobulin, and the sensitivity ranged from 74% to 93%, and specificity from 81% to 98%. The 7-Plex micronutrient assay has the potential for use as an affordable tool for population surveillance of vitamin A, iron, and iodine deficiencies as well as falciparum malarial parasitemia infectivity and inflammation. The assay is easy-to-use, requires minimal sample volume, and is scalable, rapid, and accurate-needing only a low-cost reader and basic equipment present in most reference laboratory settings and so may be employed by low and middle income countries for micronutrient surveillance to inform on status in key populations. Micronutrient deficiencies including iron, iodine, and vitamin A affect a significant portion of the world's population. Efforts to assess the prevalence of these deficiencies in vulnerable populations are challenging, partly due to measurement tools that are inadequate for assessing multiple micronutrients in large-scale population surveys. We have developed a 7-plex immunoassay for the simultaneous measurement of seven biomarkers relevant to assessing iodine, iron, and vitamin A status, inflammation and Plasmodium falciparum parasitemia by measuring levels of thyroglobulin, ferritin, soluble transferrin receptor, retinol binding protein 4, α-1-acid glycoprotein, C-reactive protein, and histidine-rich protein II. This 7-plex immunoassay technique has potential as a rapid and effective tool for use in large-scale surveys and assessments of nutrition intervention programs in low- and middle-income countries.

Depression is a frequent symptom in multiple sclerosis (MS) which has a negative impact on quality of life and cognitive status. The purpose of this study was to determine the prevalence and associated factors of depression, and status of antidepressant use in Iranian MS patients. One-hundred and sixty patients with definite MS were included. Demographic and clinical characteristics were recorded. Fatigue and depression were evaluated using the fatigue severity scale and Beck depression inventory-II. Cognitive performance and disability were examined by mini-mental status examination and expanded disability status scale. Multiple logistic regressions were used to determine the associated factors of depression and antidepressant use. The prevalence of depression and severe depression was 59.4 and 18.1 %, respectively. However, only 21.1 % of patients were on antidepressant treatment, while the prevalence of unrecognized/untreated depression was found to be as high as 44.1 %. Multivariable analysis showed that fatigue (P < 0.0001, OR = 5.98, 95 % CI = 2.9-12.3) and older age (P = 0.027, OR = 2.24, 95 % CI = 1.09-4.6) were associated with depression in MS patient. A significant association was found between fatigue and antidepressant use (P = 0.001, OR = 6.81, 95 % CI = 2.26-20.48). Our findings demonstrate that depression is significantly associated with fatigue and older age, regardless of other factors. Moreover, despite the high prevalence of depression in MS, most patients do not receive adequate treatment.

This research was planned to identify the attitudes of emergency department nurses towards patient safety. The study was performed as descriptive. The universe of the research the universe comprised hospitals defined as 3rd level according to Turkish health care classification, which provides service to all health disciplines in Istanbul. The sample consisted of emergency department (ED) nurses who work in those hospitals. The data was collected by using tools such as the "Information Questionnaire" and the "Patient Safety Attitudes Scale". In this study, the attitudes of ED nurses towards patient safety were found to be average and was not related to age, gender, education level, nursing experience, ED experience, ED certification, patient safety training, nurse's self sufficiency perception of patient safety, hospital's quality certification or ED quality certification. The attitudes of nurses towards patient safety were compared by age, gender, marital status, education level, ED experience and there was no meaningful difference. However, a meaningful difference was found between the age groups and the "defining stress" sub-dimension of the Patient Safety Attitudes Scale. ED nurses' status of certification for emergency care, patient safety training, training of quality, hospitals' or ED's quality certification status had no significant statistical difference.

Peripheral arterial disease (PAD) is associated with adverse cardiovascular events and can significantly impair patients' health status. Recently, marked methodological improvements in the measurement of PAD patients' health status have been made. The Peripheral Artery Questionnaire (PAQ) was specifically developed for this purpose. We validated a Dutch version of the PAQ in a large sample of PAD patients. Cross-sectional study. The Dutch PAQ was completed by 465 PAD patients (70% men, mean age 65+/-10 years) participating in the Euro Heart Survey Programme. Principal components analysis and reliability analyses were performed. Convergent validity was documented by comparing the PAQ with EQ-5D scales. Three factors were discerned; Physical Function, Perceived Disability, and Treatment Satisfaction (factor loadings between 0.50 and 0.90). Cronbach's alpha values were excellent (mean alpha=0.94). Shared variance of the PAQ domains with EQ-5D scales ranged from 3 to 50%. The Dutch PAQ proved to have good measurement qualities; assessment of Physical Function, Perceived Disability, and Treatment Satisfaction facilitates the monitoring of patients' perceived health in clinical research and practice. Measuring disease-specific health status in a reliable way becomes essential in times were a wide array of treatment options are available for PAD patients.

To explore intelligence quotient in boys with primary nocturnal enuresis compared with normal boys considering their socioeconomic status. A total of 152 school-aged boys (including 55 boys with primary nocturnal enuresis and 97 matched normal controls) were assessed. Boys with a history of any neurological or urological disease were excluded. Two different districts of Tehran: Khani-Abad (a poor district) and Pirouzi (a middle class district) districts were enrolled according to socioeconomic status data reported by the World Health Organization. Intelligence tests were carried out using a validated Iranian translation of the Wechsler Intelligence Scale for Children Revised. Total, as well as performance intelligence quotient and verbal intelligence quotient scores and verbal-performance discrepancy (the difference between verbal and performance intelligence quotient scores for each individual) were compared using a t-test between boys with primary nocturnal enuresis in each district and their matched controls. Considering each district separately, the total intelligence quotient score was lower in primary nocturnal enuresis cases than controls only in the lower income district (90.7 ± 23.3 vs 104.8 ± 14.7, P = 0.002). Similarly, boys with primary nocturnal enuresis ranked lower in verbal intelligence quotient (P = 0.002) and performance intelligence quotient (P = 0.004) compared with their matched normal controls only in lower income district, whereas in the higher income district, boys with primary nocturnal enuresis ranked similar in total intelligence quotient to their matched controls. Boys with primary nocturnal enuresis had a lower intelligence quotient compared with the control participants only in low-income district. It seems important to adjust the results of the intelligence quotient assessment in these children according to their socioeconomic status. © 2017 The Japanese Urological Association.

The Karnofsky Performance Status (KPS) has been used for almost 70 years for clinical assessment of patients. Our objective was to determine whether KPS is an independent predictor of post-liver transplant (LT) survival after adjusting for known confounders. Adult patients listed with UNOS from 2006 to 2016 were grouped patients into low (10-40%, n=15,103), intermediate (50-70%, n=22,183) and high (80-100%, n=13,131) KPS based on KPS scores at the time of LT after excluding those on ventilators or life support. We determined the trends in KPS before and after LT, and survival probabilities based on KPS. There was a decline in KPS scores between listing and LT and there was significant improvement after LT. The graft and patient survival differences were significantly lower (p<0.0001) in those with low KPS. After adjusting for other confounders, the hazard ratios (HR) for graft failure were 1.17 (1.12-1.22, p <0.01) for the intermediate and 1.38 (1.31-1.46, p <0.01) for the low group. Similarly, HR for patient failure were 1.18 (1.13-1.24, p <0.01) for the intermediate and 1.43 (1.35-1.52, p <0.01) for the low group. Other independent negative predictors for graft and patient survival were older age, Black ethnicity, presence of hepatic encephalopathy and donor risk index. Those who did not show significant improvements in post-LT KPS scores had poorer outcomes in all three KPS groups, but it was most obvious in the low KPS group with 1-year patient survival of 33%. The KPS, before and after LT, is an independent predictor of graft and patient survival after adjusting for other important predictors of survival. The overall health of liver transplant recipients could be assessed by a simple clinical assessment tool called Karnofsky Performance Status which assess an individual's overall functional status on 11-point scale, in increments of 10, where a score of 0 is considered dead and 100 is considered perfect health. In this study, using a large dataset, we show that the performance status before and after liver transplant could have an effect on survival. More importantly, those who have low performance status before transplant and do not show an improvement in performance status between 3-12 months after liver transplant have very poor survival.

Assessments of care including quality assessments adjusted for physiological status should include the development of new morbidities as well as mortalities. We hypothesized that morbidity, like mortality, is associated with physiological dysfunction and could be predicted simultaneously with mortality. Prospective cohort study from December 4, 2011, to April 7, 2013. General and cardiac/cardiovascular PICUs at seven sites. Randomly selected PICU patients from their first PICU admission. None. Among 10,078 admissions, the unadjusted morbidity rates (measured with the Functional Status Scale and defined as an increase of ≥ 3 from preillness to hospital discharge) were 4.6% (site range, 2.6-7.7%) and unadjusted mortality rates were 2.7% (site range, 1.3-5.0%). Morbidity and mortality were significantly (p < 0.001) associated with physiological instability (measured with the Pediatric Risk of Mortality III score) in dichotomous (survival and death) and trichotomous (survival without new morbidity, survival with new morbidity, and death) models without covariate adjustments. Morbidity risk increased with increasing Pediatric Risk of Mortality III scores and then decreased at the highest Pediatric Risk of Mortality III values as potential morbidities became mortalities. The trichotomous model with covariate adjustments included age, admission source, diagnostic factors, baseline Functional Status Scale, and the Pediatric Risk of Mortality III score. The three-level goodness-of-fit test indicated satisfactory performance for the derivation and validation sets (p > 0.20). Predictive ability assessed with the volume under the surface was 0.50 ± 0.019 (derivation) and 0.50 ± 0.034 (validation) (vs chance performance = 0.17). Site-level standardized morbidity ratios were more variable than standardized mortality ratios. New morbidities were associated with physiological status and can be modeled simultaneously with mortality. Trichotomous outcome models including both morbidity and mortality based on physiological status are suitable for research studies and quality and other outcome assessments. This approach may be applicable to other assessments presently based only on mortality.

Rheumatoid arthritis (RA) often results in impairments in upper extremities, especially in the small joints of hand. Involvement of hand brings limitations in activities of daily living. However, it is commonly observed that patient-reported functional status of hand does not always corresponds to their actual physical performance in the clinical setting. The aim of this pilot study is to investigate the relationship between patient self-reported and objectively measured hand functions in patients with RA. Twenty-six patients (51±13 years) with RA diagnosis participated in the study. Hand grip and pinch (lateral, bipod, tripod) strengths were measured and Jebsen Hand Function Test (JHFT) was performed for objective functional performance. Duruöz Hand Index and Beck Depression Inventory - Turkish version were completed by patients. Grip and all three-pinch strength results significantly correlated with Duruöz Hand Index scores (p<0.05). JHFT results except the sentence writing also correlated with the Duruöz scores (p<0.05). Our results showed that self-reported outcome scales might be used for determining functional level of hand in patients with RA in rheumatology practice. Objective quantitative functional tests are the best methods in evaluating functional level of hand, but require valid and reliable equipment with accurate calibration. Therefore, in case of unavailability of objective assessment tools, patient-reported scales may also reflect the real status of hand functions.

The Evryscope is a 24-camera robotic telescope that continuously images 8,000 square degrees in 2-minute exposures, that has been collecting data continuously since deployment to CTIO in mid-2015. The telescope provides the fast cadence observations necessary for detecting minute to tens-of-minute time-scale exoplanet transits, which would occur around small, compact host stars including White Dwarfs and Hot Subdwarfs. We are conducting target surveys for each of these types of stars searching for potential planet transit signals. Our surveys will be the largest performed to date with several thousand targets in each group and years of observations, and the only surveys with minute-scale cadence. We present the status of the surveys, our estimated detection ability, interesting candidates, and preliminary results.

In situ rainwater harvesting using dead level contours in semi-arid southern Zimbabwe: Insights on the role of socio-economic factors on performance and effectiveness in Gwanda District

NASA Astrophysics Data System (ADS)

Munamati, Muchaneta; Nyagumbo, Isaiah

Droughts and dry spells which have characterised the past decade in Zimbabwe have seen a marked increase in the promotion and use of in situ rainwater harvesting technologies (RWHTs) as a drought mitigating strategy. A number of these technologies have been tried in recent years which include dead level contours with infiltration pits and deepened contours. Although in situ RWHTs are known to increase food security in drought prone areas, the role of socio-economic factors on their performance in terms of crop yield and scaling out is still not well understood. This study sought to investigate the socio-economic factors which influence the effectiveness of dead level contours for in situ rainwater harvesting and consequently on crop yield. The study involved 14 key informants interviews and questionnaire administration to a total of 55 respondent farmers practising in situ rainwater harvesting with dead level contours. A statistical package (Statistical Package for Social Scientists, SPSS) was used to analyse relationships between performance of RWHTs and attributes such as labour, resources, gender, experience and education. The results show a strong correlation between performance and resource status ( p = 0.004). For example, within the wealthy category, 42.1% were successful, while 14.3% and 13.8% were average and poor performers respectively. Thus within the successful category, 42.1% were wealthy, while 42.1% and 15.8% were medium-rich and resource-constrained respectively. Performance rating was also significantly correlated ( p = 0.007) to gender of household head e.g., within the most successful group 94.7% were men compared to 5.3% women. There was also a significant correlation between resource status and gender ( p = 0.039) such that within the wealthy category, 69.2% of the respondents were men compared to 30.8% women. Labour was found to have no significance on performance ( p > 0.05) even though the majority of key informants (93%) alluded that the more labour resources at one’s disposal, the higher their chances of success. This is so because RWHTs are time-consuming and labour intensive. Education level and number of years using water harvesting technologies did not have a significant bearing on performance ( p > 0.05). The paper concludes that resource ownership could be a key factor in farmers’ ability to scale out RWHTs since performance was significantly linked to resource status. Women headed households were performing rather poorly in RWHTs suggesting the need for special attention to gender in the promotion of RWHTs.

The Minimum Data Set (MDS) 3.0 introduced the Brief Interview for Mental Status (BIMS), a short performance-based cognitive screener for nursing home (NH) residents. Not all residents are able to complete the BIMS and are consequently assessed by staff. We designed a Cognitive Function Scale (CFS) integrating self-report and staff-report data and present evidence of the scale's construct validity. A retrospective cohort study. The subjects consisted of 3 cohorts: (1) long-stay NH residents (N=941,077) and (2) new admissions (N=2,066,580) during 2011-2012, and (3) residents with the older MDS 2.0 assessment in 2010 and the newer MDS 3.0 assessment (n=688,511). MDS 3.0 items were used to create a single, integrated 4-category hierarchical CFS that was compared with residents' prior MDS 2.0 Cognitive Performance Scale scores and other concurrent MDS 3.0 measures of construct validity. The new CFS suggests that 28% of the long-stay cohort in 2011-2012 were cognitively intact, 22% were mildly impaired, 33% were moderately impaired, and 17% were severely impaired. For the admission cohort, the CFS noted 56% as cognitively intact, 23% as mildly impaired, 17% as moderately impaired, and 4% as severely impaired. The CFS corresponded closely with residents' prior MDS 2.0 Cognitive Performance Scale scores and with performance of Activities of Daily Living, and nurses' judgments of function and behavior in both the admission and long-stay cohorts. The new CFS is valuable to researchers as it provides a single, integrated measure of NH residents' cognitive function, regardless of the mode of assessment.

In countries where smoking is associated with lower socioeconomic status, smokers tend to perform worse on cognitive tasks than non-smokers. China is now undergoing a similar process with a recent study showing that there is a reduced cognitive performance in middle aged but not in elderly smokers. We examined the links between smoking status and cognitive functioning among vocational school students in Beijing, China. A total of 213 students aged 16-20 (98 smokers and 115 non-smokers) were recruited from three vocational schools in Beijing. Participants completed three subtests of Wechsler Adult Intelligence Scale (WAIS) (information, arithmetic, digit span) and Dysexecutive Questionnaire (DEX). Smokers also completed a cigarette smoking questionnaire and Fagerstrom Test of Nicotine Dependence (FTND). Smokers performed worse than non-smokers in tests of arithmetic and digit span forward (t = 4.25, 2.05, both P < .05). Scores on digit span backward did not differentiate smokers and non-smokers, but among smokers, the performance on this subtest was related to the age of starting smoking (r = 0.26, p < .001). Cognitive performance in smokers was not related to tobacco dependence or intensity of smoking. Compared to non-smokers, smokers had a higher total DEX score and higher scores on three of its five subscales (Inhibition, Knowing-doing dissociation and Social regulation, all p < .05). Another subscale, In-resistance, did not differentiate smokers and non-smokers, but differentiated smokers with lower and higher levels of nicotine dependence (t = -2.12, p < .05). Smokers performed worse on some cognitive tasks than non-smokers and scored higher on a questionnaire assessing executive dysfunction. Copyright © 2017. Published by Elsevier Ltd.

While gastrointestinal function is known to be closely related to psychological status, the influence of Helicobacter pylori-associated atrophic gastritis is currently unknown. We aimed to determine whether atrophic gastritis status or H. pylori infection is associated with psychological distress or depressed mood. We performed a cross-sectional, observational study involving 975 Japanese individuals (503 females; mean age, 44 ± 8 years) who underwent a health checkup. Psychological distress was defined as a Kessler-6 Scale score ≥13 and depressive mood as a Center for Epidemiological Studies Depression Scale score ≥ 16. The odds ratios with 95% confidence intervals assessing the risk of psychological distress or depressive mood associated with H. pylori infection (H. pylori-specific immunoglobulin G levels >10 U/mL) and atrophic gastritis status (pepsinogen I levels < 70 μg/L and pepsinogen I/II ratio < 3) were calculated using multiple logistic analysis adjusting for several covariates. Individuals with atrophic gastritis had a significantly higher risk of experiencing psychological distress, with younger females (<50 years) displaying the highest risk for psychological distress and depressive mood regardless of H. pylori infection status. Among females aged <50 years, H. pylori-seropositive participants with atrophic gastritis (HP+AG+) showed the highest risk of psychological distress (OR, 16.4; 95% CI, 3.45-94.9) and depression (OR, 2.86; 95% CI, 1.31-6.05), using HP-AG- status as the reference. Our findings support the results of previous animal studies regarding the psychological response to gastritis in humans. Further studies are needed to elucidate whether H. pylori eradication provides psychological benefits. © 2017 John Wiley & Sons Ltd.

Introduction: Worldwide breast cancer is the common invasive cancer among the females. The quality of life of women after treatment, which is often a mastectomy, is frequently decreased. Objective: To determine the life quality of Nepalese women post mastectomy. Materials and Methods: One hundred seven women after a mastectomy were selected and interviewed by using the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire and its Breast Specific Module to assess women’s quality of life. Result: The study findings revealed a good score on global health status/quality of life. The respondents performed well on functional and symptom scales. In the Breast Specific Module, all respondents performed poor regarding sexual function and sexual enjoyment. Global Health Status was found useful among the women involved in service/business/agriculture and the survivors using breast prosthesis. In Breast Specific Module, systemic therapy side effects showed strong statistical associations with age, marital status, occupation, education, use of breast prosthesis and co-morbidity. Body image was highly significant with age, occupation, education, use of breast prosthesis and co-morbidity. Conclusion: Based on the study findings, counseling, and a structured educational programme is recommended to improve the QOL of women after a mastectomy. Creative Commons Attribution License

BACKGROUND The purpose of this study was to investigate the potential association between socioeconomic status and ovarian reserve, anti-Mullerian hormone level, antral follicle count, and follicle stimulating hormone level in women of reproductive age. MATERIAL AND METHODS A total of 101 married women between 20-35 years of age who presented to the Department of Obstetrics and Gynecology, Health Research System In Vitro Fertilization (HRS IVF) Center between October 2014 and November 2015 and met the inclusion criteria were included in this study. The participants were divided into three socioeconomic groups using Kuppuswamy's socioeconomic status scale. Thirty-one participants were assigned to the low socioeconomic status group, 37 to the middle socioeconomic status group, and 33 to the high socioeconomic status group. On days 3-6 of the menstrual cycle, 10 mL of blood was collected from the participants for follicle stimulating hormone and anti-Mullerian hormone measurements. Transvaginal ultrasonography was performed for both ovaries for the purpose of counting antral follicles measuring 2-10 mm in diameter. RESULTS Both ovarian reserve parameters, namely anti-Mullerian hormone level and antral follicle count, exhibited a significant association with socioeconomic status (p=0.000 and p=0.000, respectively). The association between follicle stimulating hormone level and socioeconomic status was also significant (p=0.000). CONCLUSIONS A low socioeconomic status aggravated by sources of stress such as undernutrition and financial hardships affects ovarian reserve, which should be remembered in approaching infertile patients.

To analyze whether quality of life in active, healthy elderly individuals is influenced by functional status and sociodemographic characteristics, as well as psychological parameters. Study conducted in a sample of 120 active elderly subjects recruited from two open universities of the third age in the cities of São Paulo and São José dos Campos (Southeastern Brazil) between May 2005 and April 2006. Quality of life was measured using the abbreviated Brazilian version of the World Health Organization Quality of Live (WHOQOL-bref) questionnaire. Sociodemographic, clinical and functional variables were measured through crossculturally validated assessments by the Mini Mental State Examination, Geriatric Depression Scale, Functional Reach, One-Leg Balance Test, Timed Up and Go Test, Six-Minute Walk Test, Human Activity Profile and a complementary questionnaire. Simple descriptive analyses, Pearson's correlation coefficient, Student's t-test for non-related samples, analyses of variance, linear regression analyses and variance inflation factor were performed. The significance level for all statistical tests was set at 0.05. Linear regression analysis showed an independent correlation without colinearity between depressive symptoms measured by the Geriatric Depression Scale and four domains of the WHOQOL-bref. Not having a conjugal life implied greater perception in the social domain; developing leisure activities and having an income over five minimum wages implied greater perception in the environment domain. Functional status had no influence on the Quality of Life variable in the analysis models in active elderly. In contrast, psychological factors, as assessed by the Geriatric Depression Scale, and sociodemographic characteristics, such as marital status, income and leisure activities, had an impact on quality of life.

The aim of the present study was to describe the characteristics of dental fear of Chinese adult patients with periodontal disease and provide information for clinical assessment. A total of 1203 dental patients completed questionnaires that included Corach's Dental Anxiety Scales (DAS), Dental Fear Survey (DFS) and the short-form Dental Anxiety Inventory (S-DAI). Among all the patients, 366 cases were self-reported periodontal disease. The general characteristics were described, such as socio-demographics, dental attendances and oral health behaviors. The statistical analysis was performed by t-test, Mann-Whitney U test and linear regression respectively to evaluate correlations between dental fear and general characteristics according to the three scales. The prevalence of dental fear was 74% among 1203 patients, 23.4% of total with high dental fear, while 27.3% in the patients with periodontal disease. The average score of DAS and DFS for patients with periodontal disease was significantly higher than those without periodontal disease. The regression analysis indicated that gender, age, periodontal status, dental attendances and oral health behaviors were correlated with dental fear. Among 366 patients with periodontal disease, gender, dental attendances and oral health behaviors had correlation with dental fear. The analysis of DFS scale exhibited that 'drilling with handpiece' and 'injecting the anesthetic' were the most important factors to contribute to dental fear. There was high prevalence of dental fear in Chinese adult patients, particularly in patients with periodontal disease, and high level of dental fear may lead to poor periodontal status.

Background The phase III RAINBOW trial demonstrated that the addition of ramucirumab to paclitaxel improved overall survival, progression-free survival, and tumor response rate in fluoropyrimidine–platinum previously treated patients with advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma. Here, we present results from quality-of-life (QoL) and performance status (PS) analyses. Patients and methods Patients with Eastern Cooperative Oncology Group PS of 0/1 were randomized to receive ramucirumab (8 mg/kg i.v.) or placebo on days 1 and 15 of a 4-week cycle, with both arms receiving paclitaxel (80 mg/m2) on days 1, 8, and 15. Patient-reported outcomes were assessed with the QoL/health status questionnaires EORTC QLQ-C30 and EQ-5D at baseline and 6-week intervals. PS was assessed at baseline and day 1 of every cycle. Time to deterioration (TtD) in each QLQ-C30 scale was defined as randomization to first worsening of ≥10 points (on 100-point scale) and TtD in PS was defined as first worsening to ≥2. Hazard ratios (HRs) for treatment effect were estimated using stratified Cox proportional hazards models. Results Of the 665 patients randomized, 650 (98%) provided baseline QLQ-C30 and EQ-5D data, and 560 (84%) also provided data from ≥1 postbaseline time point. Baseline scores for both instruments were similar between arms. Of the 15 QLQ-C30 scales, 14 had HR < 1, indicating similar or longer TtD in QoL for ramucirumab + paclitaxel. Treatment with ramucirumab + paclitaxel was also associated with a delay in TtD in PS to ≥2 (HR = 0.798, P = 0.0941). Alternate definitions of PS deterioration yielded similar results: PS ≥ 3 (HR = 0.656, P = 0.0508), deterioration by ≥1 PS level (HR = 0.802, P = 0.0444), and deterioration by ≥2 PS levels (HR = 0.608, P = 0.0063). EQ-5D scores were comparable between treatment arms, stable during treatment, and worsened at discontinuation. Conclusion In patients with previously treated advanced gastric/GEJ adenocarcinoma, addition of ramucirumab to paclitaxel prolonged overall survival while maintaining patient QoL with delayed symptom worsening and functional status deterioration.

The aim of our study was to investigate the relationship between nutritional status (body mass index and phase angle) and psychological symptoms at admission and discharge in a residential population of anorexic patients. We also aimed to determine the evolution of the above psychological symptoms and nutrition rehabilitation from admission to discharge. Thirty-six consecutive patients were included. The evaluation was performed using the following measures at admission and discharge: body mass index, phase angle, Eating Disorders Inventory-3, Multiphasic Personality Inventory-2 and Body Uneasiness. Admission and discharge nutritional status were not correlated with psychometric scores respectively at admission and at discharge. In addition, neither the improvement in the scores on the psychometric scales between admission and discharge was correlated to body mass index, phase angle improvement. For the group as a whole there were significant improvements from admission to discharge in nutritional status, Multiphasic Personality Inventory-2-Depression, Body Uneasiness-Global Score Index and in all the composites of Eating Disorders Inventory-3. Our data showed a disconnection between nutritional status and eating disorders psychopathology and/or psychiatric comorbidities. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

To assess intelligence and its relationship with blood phenylalanine concentrations and socioeconomic status in patients with phenylketonuria after 6 to 12 years of treatment. Sixty-three children were classified according to phenylalanine levels and socioeconomic status and assessed using the Wechsler Intelligence Scale for Children. The Statistical Package for the Social Sciences (SPSS) was used to analyze phenylalanine; ANOVA was used to analyze intelligence quotients (IQ) and phenylalanine levels; and ordinal logistic regression was used to analyze the likelihood of higher IQ. The overall IQ scores of 90.5% of the children were within a range from borderline intellectual deficiency to very high intelligence; for verbal IQ this proportion was 96.8% and 92.1% had performance IQ scores within this band. The categories from low to upper-medium socioeconomic status contained 98.4% of patients' families. The likelihood of having medium to high IQ was 4.29 times greater for children with good phenylalanine control and 4.03 greater for those from higher socioeconomic strata. Treatment prevented mental retardation in 90.5% of the patients. Control of phenylalanine levels and higher socioeconomic status were associated with higher IQ scores.

Hall, Jeffery L.

2011-01-01

This paper surveys the options for, and technology status of, balloon vehicles to explore Saturn's moon Titan. A significant amount of Titan balloon concept thinking and technology development has been performed in recent years, particularly following the spectacular results from the descent and landing of the Huygens probe and remote sensing observations by the Cassini spacecraft. There is widespread recognition that a balloon vehicle on the next Titan mission could provide an outstanding and unmatched capability for in situ exploration on a global scale. The rich variety of revealed science targets has combined with a highly favorable Titan flight environment to yield a wide diversity of proposed balloon concepts. The paper presents a conceptual framework for thinking about balloon vehicle design choices and uses it to analyze various Titan options. The result is a list of recommended Titan balloon vehicle concepts that could perform a variety of science missions, along with their projected performance metrics. Recent technology developments for these balloon concepts are discussed to provide context for an assessment of outstanding risk areas and technological maturity. The paper concludes with suggestions for technology investments needed to achieve flight readiness.

To test a hypothetical model of depression in Korean women with breast cancer and to test the mediating effects of self-esteem and hope. Cross-sectional design. Participants were recruited from three general hospitals and one cancer hospital in Busan, South Korea. 214 Korean women diagnosed with breast cancer (stages I-III). All participants completed questionnaires (e.g., Zung Self-Rating Depression scale, Herth Hope Scale, Rosenberg Self-Esteem Scale, Health Self-Rating Scale in Health and Activity survey, Kang's Family Support Scale). Based on the literature, Mplus, version 3.0, was used to determine the best depression model with path analysis. Depression, self-esteem, hope, perceived health status, religious beliefs, family support, economic status, and fatigue. Self-esteem was directly affected by perceived health status, religious beliefs, family support, economic status, and fatigue. Hope was directly affected by family support, self-esteem, and how patients perceived their health status. Depression was directly affected by self-esteem and hope. The path analysis model explained 31% of the variance in depression in Korean women with breast cancer. A model of depression in Korean women with breast cancer was developed, and self-esteem and hope were mediating factors of depression. Self-esteem and hope must be considered when developing services to reduce depression in Korean women with breast cancer.

Advancing the performance of Light Water Reactors, Advanced Nuclear Fuel Cycles, and Advanced Reactors, such as the Next Generation Nuclear Power Plants, requires enhancing our fundamental understanding of fuel and materials behavior under irradiation. The capability to accurately model the nuclear fuel systems to develop predictive tools is critical. Not only are fabrication and performance models needed to understand specific aspects of the nuclear fuel, fully coupled fuel simulation codes are required to achieve licensing of specific nuclear fuel designs for operation. The backbone of these codes, models, and simulations is a fundamental understanding and predictive capability for simulating themore » phase and microstructural behavior of the nuclear fuel system materials and matrices. In this paper we review the current status of the advanced modeling and simulation of nuclear reactor cladding, with emphasis on what is available and what is to be developed in each scale of the project, how we propose to pass information from one scale to the next, and what experimental information is required for benchmarking and advancing the modeling at each scale level.« less

Forty patients with relapsing-remitting multiple sclerosis (MS) completed the 10 core Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) subtests. Means for age and education were 42.05 years (SD = 9.94) and 14.33 years (SD = 2.40). For all participants, the native language was English. The mean duration of MS diagnosis was 8.17 years (SD = 7.75), and the mean Expanded Disability Status Scale (EDSS; Kurtzke, 1983 ) score was 3.73 (SD = 1.41) with a range from 2.0 to 6.5. A control group of healthy individuals with similar demographic characteristics also completed the WAIS-IV and were provided by the test publisher. Compared to controls, patients with MS earned significantly lower subtest and composite scores. The patients' mean scores were consistently in the low-average to average range, and the patterns of performance across groups did not differ significantly, although there was a trend towards higher scores on the Verbal Comprehension Index (VCI) and lower scores on the Processing Speed Index (PSI). Approximately 78% of patients had actual Full Scale IQs that were significantly lower than preillness, demographically based IQ estimates.

Fortification of staple foods with vitamins and minerals is an effective approach to increase micronutrient intake and improve nutritional status. The specific use of condiments and seasonings as vehicles in large-scale fortification programs is a relatively new public health strategy. This paper underscores equity considerations for the implementation of large-scale fortification of condiments and seasonings as a public health strategy by examining nonexhaustive examples of programmatic experiences and pilot projects in various settings. An overview of conceptual elements in implementation research and equity is presented, followed by an examination of equity considerations for five implementation strategies: (1) enhancing the capabilities of the public sector, (2) improving the performance of implementing agencies, (3) strengthening the capabilities and performance of frontline workers, (3) empowering communities and individuals, and (4) supporting multiple stakeholders engaged in improving health. Finally, specific considerations related to intersectoral action are considered. Large-scale fortification of condiments and seasonings cannot be a standalone strategy and needs to be implemented with concurrent and coordinated public health strategies, which should be informed by a health equity lens. © 2016 New York Academy of Sciences.

The LOPES experiment at the Karlsruhe Institute of Technology has been taking radio data in the frequency range from 40 to 80 MHz in coincidence with the KASCADE-Grande air shower detector since 2003. Various experimental configurations have been employed to study aspects such as the energy scaling, geomagnetic dependence, lateral distribution, and polarization of the radio emission from cosmic rays. The high quality per-event air shower information provided by KASCADE-Grande has been the key to many of these studies and has even allowed us to perform detailed per-event comparisons with simulations of the radio emission. In this article, we give an overview of results obtained by LOPES, and present the status and perspectives of the ever-evolving experiment.

The Idaho National Laboratory, in collaboration with Idaho State University's Idaho Accelerator Center and the Los Alamos National Laboratory, continues to develop the Pulsed Photonuclear Assessment (PPA) technique for shielded nuclear material detection in large volume configurations, such as cargo containers. In recent years, the Department of Homeland Security has supported the development of a prototype PPA cargo inspection system. This PPA system integrates novel neutron and gamma-ray detectors for nuclear material detection along with a complementary and unique gray scale, density mapping component for significant shield material detection. This paper will present the developmental status of the prototype system, its detection performance using several INL Calibration Pallets, and planned enhancements to further increase its nuclear material detection capability.

Overall, a variety of indices used to measure population status throughout the sea otter’s range have provided insights for understanding the mechanisms driving the trajectory of various sea otter populations, which a single index could not, and we suggest using multiple methods to measure a population’s status at multiple spatial and temporal scales. The work described here also illustrates the usefulness of long-term data sets and/or approaches that can be used to assess population status retrospectively, providing information otherwise not available. While not all systems will be as amenable to using all the approaches presented here, we expect innovative researchers could adapt analogous multi-scale methods to a broad range of habitats and species including apex predators occupying the top trophic levels, which are often of conservation concern.

One of the key components of the Advanced Launch System (ALS) is a large liquid rocket, booster engine. To keep the overall vehicle size and cost down, this engine will probably use liquid oxygen (LOX) and a heavy hydrocarbon, such as RP-1, as propellants and operate at relatively high chamber pressures to increase overall performance. A technology program (Heavy Hydrocarbon Main Injector Technology) is being studied. The main objective of this effort is to develop a logic plan and supporting experimental data base to reduce the risk of developing a large scale (approximately 750,000 lb thrust), high performance main injector system. The overall approach and program plan, from initial analyses to large scale, two dimensional combustor design and test, and the current status of the program are discussed. Progress includes performance and stability analyses, cold flow tests of injector model, design and fabrication of subscale injectors and calorimeter combustors for performance, heat transfer, and dynamic stability tests, and preparation of hot fire test plans. Related, current, high pressure, LOX/RP-1 injector technology efforts are also briefly discussed.

To determine the experience, prevalence and severity of dental caries and its relationship with nutritional status in nursery infants 17 to 47 months of age. A cross-sectional study in 152 infants 17 to 47 months of age attending one of five day care centers of the city of Pachuca, Hidalgo was performed. Clinical examinations were performed using the methods recommended by the World Health Organization for epidemiologic studies on dental caries. We calculated the caries index (dmft), the significant caries index (SiC) as well as the treatment needs index (TNI) and the care index (CI). Nutritional status was determined using the weight and height for age, in Federico Gomez's scale. In the statistical analysis nonparametric tests were used. Mean age was 2.52 ± 0.76 years; 51.3% were boys. With regard to nutritional status, 19.1% were classified as malnourished and 19.1% were overweight/obese. The dmft index was 1.53 ± 2.52. The SiC index was 4.14, the TNI 86.3% and the CI 13.7%. Caries prevalence was 48.0%. It was observed that 33.5% of children had 1 to 3 teeth with caries experience and 14.5% had 4 or more teeth affected. Statistically significant differences for tooth decay were identified (p < 0.05) by age, height and weight but not (p> 0.05) by sex and nutritional status. This study shows that nearly half of children examined had caries experience. High treatment needs for dental caries were observed. A correlation was found between dmft index and age, weight and height. No association was identified between experience, prevalence and severity of dental caries and nutritional status of infants. It appears necessary to improve oral health preventive measures in these infants.

Returning to work is a desirable outcome of lung transplantation that is selective on attained functional status. Survival implications of post-transplant employment are unclear. The United Network for Organ Sharing registry was queried for first-time lung transplants performed from May 2005 to March 2015 in patients ages 18-64. Attainment of normal functional status post-transplant, defined as a 100 % score on the Karnofsky Performance Scale (KPS), was examined as moderating 5-year survival outcomes of work resumption, using Cox proportional hazards models. Supplemental analysis examined attainment of forced expiratory volume in 1 s (FEV1) ≥80 % predicted as moderating survival implications of post-transplant employment. Of 10,066 patients, 1824 (18 %) returned to work, while 9078 contributed follow-up data on functional status. Multivariable analysis demonstrated a protective effect of work resumption among patients who did not attain normal functional status before returning to work (HR = 0.62; 95 % CI = 0.51, 0.76; p < 0.001). This association was attenuated among transplant recipients who reached 100 % KPS while still unemployed (p < 0.001). Similarly, post-transplant survival was favorably associated with 5-year survival among patients who did not attain at least 80 % predicted FEV1 before returning to work (HR = 0.71; 95 % CI = 0.59, 0.86; p < 0.001). Early return to work after lung transplantation may benefit patients experiencing mild functional limitations. Timing the resumption of employment to coincide with attainment of maximal functional status around 1 year post transplant should be considered.

Within the context of the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study, we examined the longitudinal association of baseline depressive symptoms on inductive reasoning performance over a ten-year period between the reasoning training and control conditions (N = 1,375). At baseline, 322 participants (23%) reported elevated depressive symptoms, defined by a score ≥ 9 on the Center for Epidemiological Studies Depression scale (12-item). Differences in baseline depressive status were not associated with immediate post-training gains or with subsequent annual change in reasoning performance, suggesting that the presence of elevated baseline depressive symptoms does not impact the ability to benefit from reasoning training.

The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) is considered a valid instrument for use in Brazil. However, the previous Brazilian validation study included only 30 lung cancer patients and only measured test-retest reliability. The aim of this study was to evaluate the psychometric properties of the EORTC QLQ-C30 in a sample of cancer patients at different educational levels who completed the instrument administered by an interviewer. Data from six prospective studies conducted by the same group of researchers were combined in this study (N = 986). Reliability was assessed using Cronbach's alpha coefficient, all values of which were >0.7, with the exception of cognitive functioning, social functioning, and nausea and vomiting (α = 0.57, α = 0.69, and α = 0.68, respectively). In multi-trait scaling analysis, convergent and divergent validity were considered adequate (validity indices were 91.6 and 97.4%). In general, moderate to strong correlations were found between the subscales of the EORTC QLQ-C30 and its respective dimensions from the WHOQOL-bref, the hospital anxiety and depression scale, and the Edmonton Symptom Assessment System (ESAS) instruments. In addition, the EORTC QLQ-C30 was able to differentiate groups of patients with distinct performance statuses and types of treatment (known-group validation). Statistical analyses were also performed on educational status, yielding similar results. Detailed psychometric property data using the EORTC QLQ-C30 in Brazil are added by this study. In addition, we demonstrated that this instrument is in general reliable and valid regardless of the patient educational level.

To describe the prevalence of pressure ulcers among middle- and older-aged patients in a general medical hospital in Norway and to describe the associations between pressure ulcers and potential risk factors additional to the Braden risk score. Degrees of mobility, activity, perfusion and skin status are risk factors for development of pressure ulcer. Nurses' clinical judgements combined with risk assessment tools are effective to detect pressure ulcer risk. Cross-sectional study. The study was performed as part of a research project conducted between September 2012-May 2014 in a general hospital in the capital of Norway. Registered nurses and nursing students collected data from all eligible patients on 10 days during the students' clinical practice studies. The Braden scale was used to measure pressure ulcer risk, and skin examinations were performed to classify the skin area as normal or as indicative of pressure ulcer according to the definitions by the National Pressure Ulcer Advisory Panel. Comorbidities were collected by patient's self-report. This analysis focused on the 255 inpatients at the medical wards ≥52 years of age, most of whom had more than one comorbidity. The prevalence of pressure ulcers was 14.9% in this sample. Higher age, underweight, diabetes and worse Braden scores were factors associated with pressure ulcer, and pressure ulcer was most frequently sited at the sacrum or heel. Adding age, weight and diabetes status to pressure ulcer risk assessment scales may improve identification of patients at risk for pressure ulcers. Knowledge about strengths and limitations of risk assessment tools is important for clinical practice. Age, weight and diabetes status should be considered for inclusion in risk assessment tools for pressure ulcers in medical wards. © 2017 John Wiley & Sons Ltd.

Fatigue is a common symptom that lowers the quality of life of patients with cancer, affecting between 60% and 90% of patients. Relatively few options are available for the treatment of this debilitating condition. Modafinal, a psychostimulant developed for the treatment of narcolepsy, has been used to treat fatigue in other diseases such as multiple sclerosis, but little data support its use in cancer patients. The primary objective of this open-label pilot study was to evaluate the safety, and efficacy of modafinil in improving cancer-related fatigue (CRF) as measured by the Brief Fatigue Inventory (BFI). The effect of this agent on depression, quality of life, functional status, and cognitive function was also assessed. Modafinal was self-administered at a dose of 100 mg/d during weeks 1-2, and 200 mg during weeks 3-4. Assessments were performed at baseline, 2, and 4 weeks. BFI score was improved in 46% of patients at 2 weeks and 75% at 4 weeks (p = 0.025). Hospital Anxiety and Depression Scale scores declined at 2 and 4 weeks (p < 0.001). Most scales for neurocognitive function were unchanged. Score for all Functional Assessment of Cancer Therapy-Brain (FACT-BR) subscales (measuring quality of life), except social/family well-being, were improved (p < 0.05) at 2 and 4 weeks. Significant changes in Eastern Cooperative Oncology Group (ECOG) performance status were noted, with 40% of patients improving at least one level. Modafinil was well-tolerated with only one patient discontinuing treatment due to drug-related toxicity. In this pilot study modafinil was well-tolerated and effective for fatigue in patients with cancer. Improvements were also seen in mood, quality of life, and functional status.

 In surgery for gliomas and brain metastases, preservation of neurologic functions is essential to ensure a good quality of life and the eligibility for adjuvant therapies. This article assesses which factors could influence the functional outcome in patients with lesions located in the motor pathways.  A total of 92 patients with gliomas and metastases involving the motor pathways were studied for concerns regarding quality of life (Karnofsky performance status [KPS] and modified Rankin scale [mRS]) before and after surgical treatment supported by intraoperative neuromonitoring. Patient-related, surgery-related, and lesion-related data were recorded to identify the relationships with postoperative performance status. The relationship between lesions and the corticospinal tract were investigated with preoperative magnetic resonance imaging sequences and tractographic reconstructions.  Means of preoperative mRS and KPS were 1.91 ± 1.34 and 80.8 ± 20, and at 30 days postoperatively they were 1.93 ± 1.63 and 79.8 ± 24.4, respectively. The better preoperative performance status was a predictor of better outcome in terms of quality of life. Gender showed a statistical association with ∆KPS ( p  = 0.033) and ∆mRS ( p  = 0.031). A recurrent lesion was a predictor of poor functional outcome ( p = 0.045 for KPS at 30 days).A left-sided lesion showed a statistical association with a lesser improvement with respect to right sided. Complications were associated with a lesser functional improvement (∆mRS, ∆KPS, and clinical improvement: p  = 0.001, p  = 0.006, and p  = 0.003, respectively). Hemorrhagic complications were associated with the worst functional prognosis.  In our experience, factors associated with worse functional prognosis and quality of life were a poor preoperative performance status, female gender, operating on a recurrent lesion, involvement of the left corticospinal tract, and surgical or medical postoperative complications.

To understand the consequences of driving cessation in older adults, the authors evaluated depression in former drivers compared with active drivers. Depression (as assessed using the Center for Epidemiological Studies Depression Scale), driving status, sociodemographic factors, health status, and cognitive function were evaluated for a cohort of 1953 residents of Sonoma County, California, aged 55 years and older, as part of a community-based study of aging and physical performance. The authors re-interviewed 1772 participants who were active drivers at baseline 3 years later. At baseline, former drivers reported higher levels of depression than did active drivers even after the authors controlled for age, sex, education, health, and marital status. In a longitudinal analysis, drivers who stopped driving during the 3-year interval (i.e., former drivers) reported higher levels of depressive symptoms than did those who remained active drivers, after the authors controlled for changes in health status and cognitive function. Increased depression for former drivers was substantially higher in men than in women. With increasing age, many older adults reduce and then stop driving. Increased depression may be among the consequences associated with driving reduction or cessation.

Do repeated assessments of performance status improve predictions for risk of death among patients with cancer? A population-based cohort study.

Prior work has utilized longitudinal information on performance status to demonstrate its association with risk of death among cancer patients; however, no study has assessed whether such longitudinal information improves the predictions for risk of death. To examine whether the use of repeated performance status assessments improve predictions for risk of death compared to using only performance status assessment at the time of cancer diagnosis. This was a population-based longitudinal study of adult outpatients who had a cancer diagnosis and had at least one assessment of performance status. To account for each patient's changing performance status over time, we implemented a Cox model with a time-varying covariate for performance status. This model was compared to a Cox model using only a time-fixed (baseline) covariate for performance status. The regression coefficients of each model were derived based on a randomly selected 60% of patients, and then, the predictive ability of each model was assessed via concordance probabilities when applied to the remaining 40% of patients. Our study consisted of 15,487 cancer patients with over 53,000 performance status assessments. The utilization of repeated performance status assessments improved predictions for risk of death compared to using only the performance status assessment taken at diagnosis. When studying the hazard of death among patients with cancer, if available, researchers should incorporate changing information on performance status scores, instead of simply baseline information on performance status. © The Author(s) 2015.

The personality traits Openness to experience and Neuroticism of the five-factor model have previously been associated with memory performance in nondemented older adults, but this relationship has not been investigated in samples with memory impairment. Our examination of 50 community-dwelling older adults (29 cognitively intact; 21 with questionable dementia as determined by the Clinical Dementia Rating Scale) showed that demographic variables (age, years of education, gender, and estimated premorbid IQ) and current depressive symptoms explained a significant amount of variance of Repeatable Battery of Neuropsychological Status Delayed Memory (adjusted R (2) = 0.23). After controlling for these variables, a measure of global cognitive status further explained a significant portion of variance in memory performance (ΔR(2) = 0.13; adjusted R(2) = 0.36; p < .01). Finally, adding Openness to this hierarchical linear regression model explained a significant additional portion of variance (ΔR(2) = 0.08; adjusted R(2) = 0.44; p < .01) but adding Neuroticism did not explain any additional variance. This significant relationship between Openness and better memory performance above and beyond one's cognitive status and demographic variables may suggest that a lifelong pattern of involvement in new cognitive activities could be preserved in old age or protect from memory decline. This study suggests that personality may be a powerful predictor of memory ability and clinically useful in this heterogeneous population.

Objective: To estimate the extent to which psychophysical quantitative sensory test (QST) and patient factors (gender, age and comorbidity) predict pain, function and health status in people with shoulder disorders. To determine if there are gender differences for QST measures in current perception threshold (CPT), vibration threshold (VT) and pressure pain (PP) threshold and tolerance. Design: A cross-sectional study design. Setting: MacHAND Clinical Research Lab at McMaster University. Subjects: 34 surgical and 10 nonsurgical participants with shoulder pain were recruited. Method: Participants completed the following patient reported outcomes: pain (Numeric Pain Rating, Pain Catastrophizing Scale, Shoulder Pain and Disability Index) and health status (Short Form-12). Participants completed QST at 4 standardized locations and then an upper extremity performance-based endurance test (FIT-HaNSA). Pearson r’s were computed to determine the relationships between QST variables and patient factors with either pain, function or health status. Eight regression models were built to analysis QST’s and patient factors separately as predictors of either pain, function or health status. An independent sample t-test was done to evaluate the gender effect on QST. Results: Greater PP threshold and PP tolerance was significantly correlated with higher shoulder functional performance on the FIT-HANSA (r =0.31-0.44) and lower self-reported shoulder disability (r = -0.32 to -0.36). Higher comorbidity was consistently correlated (r =0.31-0.46) with more pain, and less function and health status. Older age was correlated to more pain intensity and less function (r =0.31-0.57). In multivariate models, patient factors contributed significantly to pain, function or health status models (r2 =0.19-0.36); whereas QST did not. QST was significantly different between males and females [in PP threshold (3.9 vs. 6.2, p < .001) and PP tolerance (7.6 vs. 2.6, p < .001) and CPT (1.6 vs. 2.3, p =.02)]. Conclusion: Psychophysical dimensions and patient factors (gender, age and comorbidity) affect self-reported and performance-based outcome measures in people with shoulder disorders. PMID:29399220

This cross-sectional study was conducted at Bahria University, Karachi, from January 2012 to December 2013, and comprised university students of different disciplines. An anonymous, self-reported questionnaire was distributed among the subjects. Convenient sampling technique was used. Demographic information, including age, gender and field of study, were obtained. Depresion was evaluated via Centre for Epidemiological Studies Depression Scale. SPSS 22 was used to analyse data. Of the 813 respondents, 334(41.1%) were males and 479(58.9%) females. The mean age was 19.9±1.8 years. Overall, 126(15.5%) subjects reported excellent, 242(29.8%) very good, 310(38.1%) good, 100(12.3%) satisfactory and 35(4.3%) not satisfactory academic performance. Residential status of students played a significant role on their academic performance (p=0.011). Breakfast eating behaviour depicted a significant association with the academic performance (p=0.04).The proportion of unsatisfactory academic performances among students having severe sleep disorder was the highest, followed by mild/moderate (p=0.01). The depression scale's item 'troubling in mind' was highly associated with academic performance (p<0.05). A constructive association existed among healthy behaviours and academic performance. .

To compare sociodemographic and clinical characteristics in patients with burning mouth syndrome (BMS) and their relationship with pain. Cross-sectional clinical study. University-Hospital. 75 BMS patients were enrolled. The study was conducted between September 2011 and March 2012 at the "Federico II" University of Naples. Demographic characteristics and clinical information including age, sex, educational level, marital status, job status, age at disease onset, oral symptoms, and triggers were collected via questionnaire interviews. To assess pain intensity the visual analogue scale (VAS) was administered. Descriptive statistics were collected, and Pearson Chi-square tests, Kruskal-Wallis nonparametric tests and the Spearman bivariate correlation were performed. The mean age was 61.17 (±11.75, female/male ratio = 3:1). The mean age at disease onset was 56.75 (±12.01). A low educational level (8.57 ± 4.95) and 80% of unemployment were found. Job status and age at disease onset correlated with the VAS scale (P = 0.019 and P = 0.015, respectively). Tongue morphology changes, taste disturbances, and intraoral foreign body sensation have a significant dependence on gender (P = 0.049, 0.001, and 0.045, respectively); intraoral foreign body sensation has a significant dependence on marital status (P = 0.033); taste disturbances have a significant dependence on job status. (P = 0.049); xerostomia has a significant dependence on age (P = 0.039); and tongue color changes and a bitter taste have a significant dependence on educational level (P = 0.040 and 0.022, respectively). Marital status and educational level have a significant dependence on the triggers (P = 0.036 and 0.049, respectively). The prevalence of BMS is higher in women, and in married, unemployed, and less highly educated patients. Burning is the most frequent symptom while stressful life events are the most frequent trigger reported. Wiley Periodicals, Inc.

To test which rehabilitative impairments are associated with higher mobility performance among community-dwelling, mobility-limited older adults. Cross-sectional analysis of baseline data from participants within a randomized controlled trial. Outpatient rehabilitation research center. Community-dwelling older adults (N=138; mean age, 75.4 y) with mobility limitations as defined by the Short Physical Performance Battery (SPPB). Not applicable. Balance measured via the Berg Balance Scale, leg strength, leg velocity, submaximal aerobic capacity, body mass index (BMI), and mobility performance as measured by the SPPB. Each of the 5 physiologic attributes (unipedal balance, leg strength, leg velocity, submaximal aerobic capacity, BMI) was categorized into tertiles by using lower values as reference for impairment status. Within an adjusted model, measures associated with higher SPPB performance (>9) included a BBS score greater than or equal to 54 (odds ratio [OR]=4.54; 95% confidence interval [CI], 1.11-18.60), leg strength greater than or equal to 21.5 N/kg (OR=30.35; 95% CI, 5.48-168.09), leg velocity .0101 to .0129 m.s(-1).kg(-1) (OR=5.31; 95% CI, 1.25-22.57), and leg velocity greater than or equal to .0130 m.s(-1).kg(-1) (OR=22.86; 95% CI, 3.88-134.75). Our investigation highlights the importance of rehabilitative impairments in leg strength, leg velocity, and balance as being associated with mobility status as measured by the SPPB. In our sample of participants within an exercise trial, submaximal aerobic capacity and BMI status were not associated with mobility performance. These findings suggest that the augmentation of not only leg strength and balance but also leg velocity may be important in the rehabilitative care of mobility-limited older adults.

To determine medical, ophthalmologic, and demographic predictors of cognitive function scores as measured by the Telephone Interview for Cognitive Status (TICS), an adaptation of the Folstein Mini-Mental Status Exam. A secondary objective was to perform an item-by-item analysis of the TICS scores to determine which items correlated most highly with the overall scores. Cross-sectional cohort study. The Glaucoma Consultation Service of the Massachusetts Eye and Ear Infirmary. 472 of 565 consecutive patients age 65 and older who were seen at the Glaucoma Consultation Service between November 1, 1987 and October 31, 1988. Each subject had a standard visual examination and review of medical history at entry, followed by a telephone interview that collected information on demographic characteristics, cognitive status, health status, accidents, falls, symptoms of depression, and alcohol intake. A multivariate linear regression model of correlates of TICS score found the strongest correlates to be education, age, occupation, and the presence of depressive symptoms. The only significant ocular condition that correlated with lower TICS score was the presence of surgical aphakia (model R2 = .46). Forty-six percent (216/472) of patients fell below the established definition of normal on the mental status scale. In a logistic regression analysis, the strongest correlates of an abnormal cognitive function score were age, diabetes, educational status, and occupational status. An item analysis using step-wise linear regression showed that 85 percent of the variance in the TICS score was explained by the ability to perform serial sevens and to repeat 10 items immediately after hearing them. Educational status correlated most highly with both of these items (Kendall Tau R = .43 and Kendall Tau R = .30, respectively). Education, occupation, depression, and age were the strongest correlates of the score on this new screening test for assessing cognitive status. These factors were stronger correlates of the TICS score than chronic medical conditions, visual loss, or medications. The Telephone Interview for Cognitive Status is a useful instrument, but it may overestimate the prevalence of dementia in studies with a high prevalence of persons with less than a high school education.

Preference-based Health status in a German outpatient cohort with multiple sclerosis

2013-01-01

Background To prospectively determine health status and health utility and its predictors in patients with multiple sclerosis (MS). Methods A total of 144 MS patients (mean age: 41.0 ±11.3y) with different subtypes (patterns of progression) and severities of MS were recruited in an outpatient university clinic in Germany. Patients completed a questionnaire at baseline (n = 144), 6 months (n = 65) and 12 months (n = 55). Health utilities were assessed using the EuroQol instrument (EQ-5D, EQ VAS). Health status was assessed by several scales (Expanded Disability Severity Scale (EDSS), Modified Fatigue Impact Scale (M-FIS), Functional Assessment of MS (FAMS), Beck Depression Inventory (BDI-II) and Multiple Sclerosis Functional Composite (MSFC)). Additionally, demographic and socioeconomic parameters were assessed. Multivariate linear and logistic regressions were applied to reveal independent predictors of health status. Results Health status is substantially diminished in MS patients and the EQ VAS was considerably lower than that of the general German population. No significant change in health-status parameters was observed over a 12-months period. Multivariate analyses revealed M-FIS, BDI-II, MSFC, and EDSS to be significant predictors of reduced health status. Socioeconomic and socio-demographic parameters such as working status, family status, number of household inhabitants, age, and gender did not prove significant in multivariate analyses. Conclusion MS considerably impairs patients’ health status. Guidelines aiming to improve self-reported health status should include treatment options for depression and fatigue. Physicians should be aware of depression and fatigue as co-morbidities. Future studies should consider the minimal clinical difference when health status is a primary outcome. PMID:24089999

Participation in the community socially by stroke victims is an optimal outcome post-stroke. We carried out a cohort study to evaluate a model for community participation by Thai stroke victims 6 months post-stroke. Six standardized instruments were used to assess the patient's status 1, 3 and 6 months after stroke. These were the modified Rankin Scale, the National Institute of Health Stroke Scale, the Fugl-Meyer Assessment and the Berg Balance Scale. The performance of activities of daily living and community ambulation were measured using the Barthel Index and walking velocity. Participation in the community was measured by the Stroke Impact Scale. The outcomes demographics and stroke related variables were analyzed using the Generalized Estimating Equations. Of the 98 subjects who completed the follow-up assessment, 72 (86.5%) felt they had more participation in the community 6 months post-stroke. The level of disability, performance of independent activities and length of time receiving physical therapy were associated with the perceived level of participation in the community among stroke victims 6 months post-stroke. To achieve a goal of good participation in the community among stroke victims, health care planning should focus on improving the stroke victim's ability to independently perform daily activities. The average length of physical therapy ranged from 1 to 6 months, at 3 to 8 hours/month. Clinical practice guidelines should be explored to optimize participation in the community.

To assess the performance of the German version of the Anorectic Behavior Observation Scale (ABOS) as a parent-report screening instrument for eating disorders (ED) in their children. Parents of 101 ED female patients (80 with Anorexia Nervosa; 21 with Bulimia Nervosa) and of 121 age- and socioeconomic status (SES)-matched female controls completed the ABOS. Confirmatory factor analysis supported the original three-factor structure model of the ABOS. Cronbach's alpha coefficients indicated good internal consistency for the three factors and the total score in the total sample. The best cut-off point (100% sensitivity and specificity) in the German version was >or=23. The ABOS may be a useful additional instrument for assessing ED.

[Reform of occupational insurance medical treatment from the perspective of an accident insurance consultant].

Kalbe, P

2016-11-01

The reform of occupational insurance medical treatment in 2011 also resulted in many changes for occupational insurance consultants in private practice. The transformation of the physicians participating in treatment status (H-Arzt) to accident insurance consultant status (D-Arzt) has resulted in a significant increase in numbers in outpatient fields, which in some cases leads to increased competition. The tentative flexibilization of the conditions for participation of a D‑Arzt is welcomed but must be broadened to safeguard the future. The relaxation of obligatory attendance of a D‑Arzt is contemporary and is welcomed. The regularly checked obligation for further education initially led to irritation but has now been extensively coordinated with the mandatory further education for contract physicians. As from 1 January 2016 many smaller alterations and specifications in the implementation regulations have been undertaken. The scale of charges for physicians in invoicing with accident insurance companies as with other scales of charges is urgently in need of reform with respect to the performance rating and in particular to the classification.

The aim of the study is to determine whether certain demographic, clinical, and psychosocial traits are associated with higher levels of felt stigma among persons with epilepsy (PWE) patients followed at a level 4 epilepsy center. We performed a direct survey of 182 consenting patients that included the Epilepsy Stigma Scale. On univariate analysis, higher levels of perceived stigma were associated with age, marital status, race, driving, work status, seizure etiology, Quality of Life in Epilepsy-10 (QOLIE-10) scores, and health literacy. Among coping reactions, the use of denial, behavioral disengagement and venting were also associated with higher degrees of felt stigma. Using multiple linear regression, being single, poorer QOLIE-10 scores, difficulties understanding written information, and the use of behavioral disengagement were independently associated with poorer scores on the Epilepsy Stigma Scale. Our study paints a compelling profile of a PWE who has greater perceived stigma. Programs that increase the level of social support, improve health literacy, and enhance quality of life may also help decrease the amount of felt stigma among PWE.

The adequacy of body fluids is important for athletes in supporting performance. The purpose of this research was to determine the hydration status of athletes before and after training. The study was a qualitative descriptive by using random sampling. All athletes were trained for approximately 60 minutes. And they were asked to analyze their body fluid pattern routinely. Data were obtained through urine color measurement. The urinary was taken at pre and post training and was immediately assessed in the afternoon. Based on pre-training urine samples, a mean of urine color scale was 3.1 point. It meant that only 31.2% of the athletes were in dehydrated condition. However, after exercising, urine color index showed scale 4.1. And 62.5% of the athletes experienced dehydration. The results showed that there was a significant change in hydration level before and after training. It can be concluded that training for a long time increases the risk of dehydration. It is important for athletes to meet the needs of body fluids in order to avoid functional impairment in the body during sports activities.

This report describes the levels of physical function in U.S. Chinese older adults utilizing self-reported and performance-based measures, and examines the association between sociodemographic characteristics and physical function. The Population Study of Chinese Elderly in Chicago enrolled an epidemiological cohort of 3,159 community-dwelling Chinese older adults aged 60 and older. We collected self-reported physical function using Katz activities of daily living and Lawton instrumental activities of daily living items, the Index of Mobility scale, and the Index of Basic Physical Activities scale. Participants were also asked to perform tasks in chair stand, tandem stand, and timed walk. We computed Pearson and Spearman correlation coefficients to examine the correlation between sociodemographic and physical function variables. A total of 7.8% of study participants experienced activities of daily living impairment, and 50.2% experienced instrumental activities of daily living impairment. With respect to physical performance testing, 11.4% of the participants were not able to complete chair stand for five times, 8.5% of the participants were unable to do chair stands at all. Older age, female gender, lower education level, being unmarried, living with fewer people in the same household, having fewer children, living fewer years in the United States, living fewer years in the community, and worsening health status were significantly correlated with lower levels of physical function. Utilizing self-reported and performance-based measures of physical function in a large population-based study of U.S. Chinese older adults, our findings expand current understanding of minority older adults' functional status. © The Author 2014.

Background The past decades have seen phenomenal growth in the availability of inexpensive and powerful personal computing devices. Efforts to leverage these devices to improve health care outcomes promise to remake many aspects of healthcare delivery, but remain in their infancy. New method We describe the development of a mobile health platform designed for daily measures of functional status in ambulatory, community dwelling subjects, including those who have Alzheimer’s disease or related neurodegenerative disorders. Using Smartwatches and Smartphones we measure subject overall activity and outdoor location (to derive their lifespace). These clinically-relevant measures allow us to track a subject’s functional status in their natural environment over prolonged periods of time without repeated visits to healthcare providers. Functional status metrics are integrated with medical information and caregiver reports, which are used by a caregiving team to guide referrals for physician/APRN/NP care. Comparison with Existing Methods We describe the design tradeoffs involved in all aspects of our current system architecture, focusing on decisions with significant impact on system cost, performance, scalability, and user-adherence. Results We provide real-world data from current subject enrollees demonstrating system accuracy and reliability. Conclusions We document real-world feasibility in a group of men and women with dementia that Smartwatches/Smartphones can provide long-term, relevant clinical data regarding individual functional status. We describe the underlying considerations of this system so that interested organizations can adapt and scale our approach to their needs.

Robust control of combustion instabilities

NASA Astrophysics Data System (ADS)

Hong, Boe-Shong

Several interactive dynamical subsystems, each of which has its own time-scale and physical significance, are decomposed to build a feedback-controlled combustion- fluid robust dynamics. On the fast-time scale, the phenomenon of combustion instability is corresponding to the internal feedback of two subsystems: acoustic dynamics and flame dynamics, which are parametrically dependent on the slow-time-scale mean-flow dynamics controlled for global performance by a mean-flow controller. This dissertation constructs such a control system, through modeling, analysis and synthesis, to deal with model uncertainties, environmental noises and time- varying mean-flow operation. Conservation law is decomposed as fast-time acoustic dynamics and slow-time mean-flow dynamics, served for synthesizing LPV (linear parameter varying)- L2-gain robust control law, in which a robust observer is embedded for estimating and controlling the internal status, while achieving trade- offs among robustness, performances and operation. The robust controller is formulated as two LPV-type Linear Matrix Inequalities (LMIs), whose numerical solver is developed by finite-element method. Some important issues related to physical understanding and engineering application are discussed in simulated results of the control system.

Status competition, inequality, and fertility: implications for the demographic transition

PubMed Central

Kaplan, Hillard S.; Hooper, Paul L.

2016-01-01

The role that social status plays in small-scale societies suggests that status may be important for understanding the evolution of human fertility decisions, and for understanding how such decisions play out in modern contexts. This paper explores whether modelling competition for status—in the sense of relative rank within a society—can help shed light on fertility decline and the demographic transition. We develop a model of how levels of inequality and status competition affect optimal investment by parents in the embodied capital (health, strength, and skills) and social status of offspring, focusing on feedbacks between individual decisions and socio-ecological conditions. We find that conditions similar to those in demographic transition societies yield increased investment in both embodied capital and social status, generating substantial decreases in fertility, particularly under conditions of high inequality and intense status competition. We suggest that a complete explanation for both fertility variation in small-scale societies and modern fertility decline will take into account the effects of status competition and inequality.

To examine associations between multitasking ability defined by performance on a complex task integrating multiple cognitive domains and vocational functioning in multiple sclerosis (MS). Survey data collection. Laboratory with referrals from an outpatient clinic. Community-dwelling individuals with MS (N=30) referred between October 2011 and June 2012. Not applicable. The modified Six Elements Test (SET) to measure multitasking ability, Fatigue Severity Scale to measure fatigue, several neuropsychological measures of executive functioning, and vocational status. Among the sample, 60% of individuals have reduced their work hours because of MS symptoms (cutback employment group) and 40% had maintained their work hours. Among both groups, SET performance was significantly associated with performance on several measures of neuropsychological functioning. Individuals in the cutback employment group demonstrated significantly worse overall performance on the SET (P=.041). Logistic regression was used to evaluate associations between SET performance and vocational status, while accounting for neuropsychological performance and fatigue. The overall model was significant (χ(2)3=8.65, P=.032), with fatigue [Exp(B)=.83, P=.01] and multitasking ability [Exp(B)=.60, P=.043] retained as significant predictors. Multitasking ability may play an important role in performance at work for individuals with MS. Given that multitasking was associated with vocational functioning, future efforts should assess the usefulness of incorporating multitasking ability into rehabilitation planning.

To our present best knowledge, microwave SQUID multiplexing (μ MUXing) is the most suitable technique for reading out large-scale low-temperature microcalorimeter arrays that consist of hundreds or thousands of individual pixels which require a large readout bandwidth per pixel. For this reason, the present readout strategy for metallic magnetic calorimeter (MMC) arrays combining an intrinsic fast signal rise time, an excellent energy resolution, a large energy dynamic range, a quantum efficiency close to 100% as well as a highly linear detector response is based on μ MUXing. Within this paper, we summarize the state of the art in MMC μ MUXing and discuss the most recent results. This particularly includes the discussion of the performance of a 64-pixel detector array with integrated, on-chip microwave SQUID multiplexer, the progress in flux ramp modulation of MMCs as well as the status of the development of a software-defined radio-based room-temperature electronics which is specifically optimized for MMC readout.

Family-based intervention is essential for adolescents with behavioral problems. However, limited data are available on the relationship between family-based factors and adolescent internet addiction (AIA). We aimed to examine this relationship using a representative sample of Shanghai adolescents. In October 2007, a total of 5122 adolescents were investigated from 16 high schools via stratified-random sampling in Shanghai. Self-reported and anonymous questionnaires were used to assess parent-adolescent interaction and family environments. AIA was assessed by DRM-52 Scale, developed from Young's Internet-addiction Scale, using seven subscales to evaluate psychological symptoms of AIA. Adjusting for adolescents' ages, genders, socio-economic status, school performances and levels of the consumption expenditure, strong parental disapproval of internet-use was associated with AIA (vs. parental approval, OR = 2.20, 95% CI: 1.24-3.91). Worse mother-adolescent relationships were more significantly associated with AIA (OR = 3.79, 95% CI: 2.22-6.48) than worse father-adolescent relationships (OR = 1.76, 95% CI: 1.10-2.80). Marital status of "married-but-separated" and family structure of "left-behind adolescents" were associated with symptoms of some subscales. When having high monthly allowance, resident students tended to develop AIA but commuter students did not. Family social-economic status was not associated with the development of AIA. The quality of parent-adolescent relationship/communication was closely associated with the development of AIA, and maternal factors were more significantly associated with development of AIA than paternal factors. Family social-economic status moderated adolescent internet-use levels but not the development of AIA.

To determine whether anxiety or depression is associated with takotsubo stress cardiomyopathy (TSCM). A retrospective case-control study was conducted among 73 TSCM cases and 111 acute coronary syndrome (ACS) controls matched for age, sex, and cardiac catheterization date. The study was conducted between May 1, 2009, and February 28, 2010. The Hospital Anxiety and Depression Scale was completed by all participants after hospital discharge. The Hospital Anxiety and Depression Scale was used to assess psychological distress with measurement of anxiety and depression scores. The presence of a stressful emotional or physical trigger before the TSCM presentation was determined. Univariate testing was performed to quantify the associations between anxiety and depression and TSCM trigger status. Multivariable logistic regression was used to quantify the independent associations between anxiety and depression and TSCM status after controlling for relevant covariates. The mean anxiety score was 6.7 ± 4.7 for TSCM cases versus 5.4 ± 3.4 for ACS controls (P = .06). The mean depression score was 4.3 ± 3.7 for TSCM cases versus 4.0 ± 3.1 for controls (P = .61). Anxiety was particularly associated with TSCM status with an emotional trigger (P = .05). After multivariable adjustment, anxiety (OR = 1.13; 95% CI, 1.01-1.26; P = .03) was associated with TSCM status but depression was not (OR = 0.94; 95% CI, 0.83-1.05; P = .29). In comparison with a control group with ACS, patients who presented with TSCM have higher levels of anxiety but not depression.

Arachidonic acid (ARA) and DHA, supplied primarily from the mother, are required for early development of the central nervous system. Thus, variations in maternal ARA or DHA status may modify neurocognitive development. We investigated the relationship between maternal ARA and DHA status in early (11·7 weeks) or late (34·5 weeks) pregnancy on neurocognitive function at the age of 4 years or 6-7 years in 724 mother-child pairs from the Southampton Women's Survey cohort. Plasma phosphatidylcholine fatty acid composition was measured in early and late pregnancy. ARA concentration in early pregnancy predicted 13 % of the variation in ARA concentration in late pregnancy (β=0·36, P<0·001). DHA concentration in early pregnancy predicted 21 % of the variation in DHA concentration in late pregnancy (β=0·46, P<0·001). Children's cognitive function at the age of 4 years was assessed by the Wechsler Preschool and Primary Scale of Intelligence and at the age of 6-7 years by the Wechsler Abbreviated Scale of Intelligence. Executive function at the age of 6-7 years was assessed using elements of the Cambridge Neuropsychological Test Automated Battery. Neither DHA nor ARA concentrations in early or late pregnancy were associated significantly with neurocognitive function in children at the age of 4 years or the age of 6-7 years. These findings suggest that ARA and DHA status during pregnancy in the range found in this cohort are unlikely to have major influences on neurocognitive function in healthy children.

The aim of this study is to compare the Wechsler Intelligence Scale for Children ® - fourth edition IV (WISC IV) intellectual profile of two groups of children with specific learning disorder, a group of bilingual children and a group of monolingual Italian children, in order to identify possible significant differences between them. A group of 48 bilingual children and a group of 48 Italian monolingual children were included in this study. A preliminary comparison showed the homogeneity of the two groups regarding learning disorder typology and sociodemographic characteristics (age at WISC IV assessment, sex and years of education in Italy) with the exception of socioeconomic status. Socioeconomic status was then used as a covariate in the analysis. Even if the two groups were comparable in specific learning disorder severity and, in particular, in the text comprehension performance, our findings showed that the WISC IV performances of the bilingual group were significantly worse than the Italian group in Full Scale Intelligence Quotient ( P =0.03), in General Ability Index ( P =0.03), in Working Memory Index ( P =0.009) and in some subtests and clusters requiring advanced linguistic abilities. These results support the hypothesis of a weakness in metalinguistic abilities in bilingual children with specific learning disorders than monolinguals. If confirmed, this result must be considered in the rehabilitation treatment.

The purpose of this study was twofold: (a) to evaluate the scaling assumptions and component structure of and present normative data for the Rosenberg Self-Esteem Scale (RSES) using a sample of US adults (N = 503), both overall and across demographic subgroups and (b) to provide new data regarding the relationship between the two RSES subcomponents of self-competence (SC) and self-liking (SL), and other demographic and clinical variables. As hypothesized, all psychometric tests supported the underlying structure of the RSES. Overall RSES scores varied significantly across age, racial and ethnic, education, employment status, income, and marital status groups. Furthermore, differences between SC and SL were also found across groups differing in gender, age, employment status, and marital status groups. The implications and limitations of this study are discussed, with an emphasis on clinical relevance.

Parkinson's disease (PD) patients are at a higher risk of malnutrition. The prevalence has been estimated to 0-24%, while 3%-60% of PD patients are reported to be at risk of malnutrition. To date, there is no clear explanation for malnutrition in these patients. The aim of this study was to determine the prevalence of malnutrition and to analyze factors that influence its appearance. The Mini Nutritional Assessment (MNA) was used to determine normal nutritional status; at risk of malnutrition; and already malnourished status. The Unified Parkinson's Disease Rating Scale (UPDRS) parts III and IV, Hoehn and Yahr scale (H&Y scale), Beck Depression Inventory (BDI), Mini Mental State Examination (MMSE), Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale - eating part (QUIP-RS) and Mini Nutritional Assessment (MNA) were used to evaluate the factors affecting patient nutritional status. Out of 96 patients, 55,2% were at risk of malnutrition, while 8,3% had already been malnourished. Age, H&Y scale, UPDRS part III, 'off' periods and depression influence negatively on MNA. More patients with 'off' periods were rigor dominant. Thyroid gland hormone therapy was related to malnutrition, while patients with normal nutritional status used ropinirole more often than pramipexole. Factors affecting nutritional status are age, motor symptoms and stage severity, 'off' states, rigidity dominant type with 'off' states, and thyroid hormone replacement therapy. Ropinirole exhibited the possible 'protective' effect against malnutrition. Copyright © 2017 Elsevier B.V. All rights reserved.

The commonly used available scales for measurement of socio-economic status (SES) with some cross regional applicability are old and have lost their relevance. There is a need for the development of a valid and reliable instrument for measurement of SES in rural and urban communities in India. The present study was undertaken to develop a cross regionally applicable scale for the purpose of enlisting true measures of socio-economic items applicable in multilingual, multicultural, multireligious, setting of the country. For developing the scale, seven indicators (house, materials possession, education, occupation, monthly income, land, social participation and understanding), presumably determining the socioeconomic status were selected. These indicators were named as profiles. Thus, initially the scale had seven profiles and every profile contained five alternatives. This instrument was prepared on a 10-point scale. Weightage system of scoring (varying from 2 to 10) was followed from first to sixth profile while the additive pattern of scoring was followed in seventh profile. The final version of the scale was arrived at through three trial administrations on rural and urban families. The basis of selection of the families for the first two trials was stratified random. The validity and reliability of the scale was established through a defined visual analogue scale (VAS) and test-retest methods. Both the initial version as well as the final version of the scale for the measurement of SES of incumbents had seven profiles. The difference between the two versions was in terms of contents and range of items in different categories of SES. The final version was arrived at through field trials and suggestions of the experts. The reliability of the scale was high with a correlation coefficient of 0.998. The new scale appears to be a valid and reliable instrument for the assessment of socio-economic status of the families/individuals from urban as well as rural areas in India.

Treatment Techniques and Site Considerations Regarding Dysphagia-Related Quality of Life in Cancer of the Oropharynx and Nasopharynx

Purpose: To assess the relationship for oropharyngeal (OP) cancer and nasopharyngeal (NP) cancer between the dose received by the swallowing structures and the dysphagia related quality of life (QoL). Methods and Materials: Between 2000 and 2005, 85 OP and 47 NP cancer patients were treated by radiation therapy. After 46 Gy, OP cancer is boosted by intensity-modulated radiation therapy (IMRT), brachytherapy (BT), or frameless stereotactic radiation/cyberknife (CBK). After 46 Gy, the NP cancer was boosted with parallel-opposed fields or IMRT to a total dose of 70 Gy; subsequently, a second boost was given by either BT (11 Gy) or stereotacticmore » radiation (SRT)/CBK (11.2 Gy). Sixty OP and 21 NP cancer patients responded to functional and QoL questionnaires (i.e., the Performance Status Scales, European Organization for Research and Treatment of Cancer H and N35, and M.D. Anderson Dysphagia Inventory). The swallowing muscles were delineated and the mean dose calculated using the original three-dimensional computed tomography-based treatment plans. Univariate analyses were performed using logistic regression analysis. Results: Most dysphagia problems were observed in the base of tongue tumors. For OP cancer, boosting with IMRT resulted in more dysphagia as opposed to BT or SRT/CBK. For NPC patients, in contrast to the first booster dose (46-70 Gy), no additional increase of dysphagia by the second boost was observed. Conclusions: The lowest mean doses of radiation to the swallowing muscles were achieved when using BT as opposed to SRT/CBK or IMRT. For the 81 patients alive with no evidence of disease for at least 1 year, a dose-effect relationship was observed between the dose in the superior constrictor muscle and the 'normalcy of diet' (Performance Status Scales) or 'swallowing scale' (H and N35) scores (p < 0.01)« less

To identify the direct and indirect effects of nutritional status, physical function, and cognitive function on activities of daily living in Japanese older adults requiring long-term care. In total, 179 participants aged ≥ 65 years who were eligible for long-term care insurance (mean age 85.5 ± 7.8 years) were recruited for this study. Nutritional status (Mini Nutritional Assessment, Short Form) and physical function (Short Physical Performance Battery) were examined. Activities of daily living, cognitive function and frailty were assessed using the Barthel Index, Mini-Mental State Examination and Clinical Frailty Scale, respectively. Path analysis was used to determine relationships between these factors and the activities of daily living. For Japanese older adults requiring long-term care, pathways were modeled for nutritional status, physical function and the activities of daily living. The total effect of nutritional status was 0.516 (P<0.001). The indirect effect of nutritional status through physical function on the activities of daily living was 0.458 (P<0.001). Finally, no significant direct effect of nutritional status on activities of daily living was observed (b=0.058, P=0.258). The present study identified the complex pathway from nutritional status to the activities of daily living through physical function in aged Japanese people requiring long-term care. These findings suggest that maintaining good nutritional status and nutritional support might delay physical function decline, and prolong the activities of daily living. © 2013 Japan Geriatrics Society.

To examine the relationship between child self-report and parent proxy report of health-related quality of life (HRQL) and how parents' mental health status relates to the HRQL ratings 6 years after minor to severe injury of the child. This cross-sectional cohort study was performed at a regional pediatric trauma center in Stockholm, Sweden. The PedsQL 4.0 versions for ages 5-7, 8-12, and 13-18 years were completed by 177 child-parent dyads 6 years after injury to the child. The parents also rated their own mental health through the mental health domain (MH) in the SF-36 Health Survey. The children's median age was 13 years (IQR 10-16 years), 54 % were males, and the median ISS was 5 (IQR 2-9). Most of the parents were female (77 %), born in Sweden (79 %), and half had university degrees. There was no statistically significant difference between child self-report and parent proxy report in any of the PedsQL 4.0 scales or summary scales. The levels of agreement between child self-report and parent proxy reports were excellent (ICC ≥ 0.80) for all scales with the exception of emotional functioning (ICC 0.53) which also was the scale with the lowest internal consistency in child self-report (α 0.60). Multiple regression analyses showed that worse parental mental health status correlated with worse child self-report and parent proxy report of children's HRQL. Children and their parents' reports on child's HRQL were in agreement. Decreased mental health in parents was associated with lower scores on parent proxy reports and child self-reports of HRQL after injury. The current investigation highlights the possible relationship between parent's mental health status and children's HRQL long after an injury, which should be considered in future investigations and in clinical care.

The authors prospectively explored the consequences of hip fracture with regard to discharge placement, functional status, and mortality using the Survey on Assets and Health Dynamics Among the Oldest Old (AHEAD). Data from baseline (1993) AHEAD interviews and biennial follow-up interviews were linked to Medicare claims data from 1993–2005. There were 495 postbaseline hip fractures among 5,511 respondents aged ≥69 years. Mean age at hip fracture was 85 years; 73% of fracture patients were white women, 45% had pertrochanteric fractures, and 55% underwent surgical pinning. Most patients (58%) were discharged to a nursing facility, with 14% being discharged to their homes. In-hospital, 6-month, and 1-year mortality were 2.7%, 19%, and 26%, respectively. Declines in functional-status-scale scores ranged from 29% on the fine motor skills scale to 56% on the mobility index. Mean scale score declines were 1.9 for activities of daily living, 1.7 for instrumental activities of daily living, and 2.2 for depressive symptoms; scores on mobility, large muscle, gross motor, and cognitive status scales worsened by 2.3, 1.6, 2.2, and 2.5 points, respectively. Hip fracture characteristics, socioeconomic status, and year of fracture were significantly associated with discharge placement. Sex, age, dementia, and frailty were significantly associated with mortality. This is one of the few studies to prospectively capture these declines in functional status after hip fracture.

Abstract Numerous previous studies have investigated the mental health status of medical staff in China and explored its associated determinate factors; however, scope and methods associated with these have introduced uncertainty regarding the results. The aim of this study was to perform a comprehensive examination of the mental health status of Chinese medical staff and its relative risk factors based on a cross-sectional survey. We conducted a broad area, cross-sectional, questionnaire-based survey of Chinese medical workers. Participants were randomly selected from 27 hospitals in the Heilongjiang province. The questionnaire that was distributed consisted of 5 parts: the demographic characteristics of the participant; questions related to the relative risk factors of psychological health; the posttraumatic stress disorder (PTSD) Checklist-Civilian Version (PCL-C); the Self-rating Depression Scale (SDS); and the Self-rating Anxiety Scale (SAS). The last 3 components were used to evaluate the mental health status of the target population. Logistic and linear regression were used to analyze the determinate factors of the mental health status of Chinese medical staff. Of the 1679 questionnaires distributed, 1557 medical workers responded (response rate: 92.73%; male: 24.1%; female 75.9%). The results of mental health status self-assessments indicated that 32.3% of participants were considered to have some degree of PTSD (based on the PCL-C). The SDS index was 0.67 and the mean score from SAS was 55.26; a result higher than found in the general population. Multivariate logistic regression analysis revealed that being female, dissatisfaction or average satisfaction with income, and good or very good self-perceived psychological endurance when faced with an emergency were associated with a reduction of PTSD symptoms. A frequency of verbal abuse incidents greater than 4 was associated with an increase in PTSD symptoms. The mental health status of Chinese medical staff is poor. While the determinate factors based on different measurement standards were not completely consistent, the overlapping major risk factors identified that influenced psychological health were the amount of education, the perceived level of respect, and psychological endurance.

Adverse effects of severe maternal iodine deficiency in pregnancy on fetal brain development are well-established, but the effects of milder deficiency are uncertain. Most studies examine iodine status in pregnancy; less is known about iodine nutrition before conception. We examined relations between maternal preconception iodine status and offspring cognitive function, within a prospective mother-offspring cohort. Maternal iodine status was assessed through the use of the ratio of iodine:creatinine concentrations (I/Cr) in spot urine samples [median (IQR) period before conception 3.3 y (2.2-4.7 y)]. Childhood cognitive function was assessed at age 6-7 y. Full-scale IQ was assessed via the Wechsler Abbreviated Scale of Intelligence, and executive function through the use of tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB). Analyses (n = 654 mother-child dyads) were adjusted for potential confounders including maternal intelligence, education, and breastfeeding duration. The median (IQR) urinary iodine concentration was 108.4 µg/L (62.2-167.8 µg/L) and the I/Cr ratio 114 µg/g (76-164 µg/g). The preconception I/Cr ratio was positively associated with child IQ, before and after adjustment for potential confounding influences [β = 0.13 (95% CI: 0.04, 0.21)/SD, P = 0.003]. 8.9% of women had a preconception urinary I/Cr ratio <50 µg/g; compared with those with an I/Cr ratio ≥150 µg/g, the IQ of their offspring was 0.49 (95% CI: 0.79, 0.18) SD lower. There were no associations with the executive function outcomes assessed via CANTAB, before or after adjustment for confounders. The positive association between iodine status before conception and child IQ provides some support for demonstrated links between low maternal iodine status in pregnancy and poorer cognitive function reported in other studies. However, given the negative effects on school performance previously observed in children born to iodine-deficient mothers, the lack of associations with measures of executive function in the present study was unexpected. Further data are needed to establish the public health importance of low preconception iodine status.

There have been few large-scale, real world studies in Spain to assess change in pain and quality of life (QOL) outcomes in cancer patients with moderate to severe pain. This study aimed to assess changes on both outcomes after 3 months of usual care and to investigate factors associated with change in QoL. Large, multi-centre, observational study in patients with lung, head and neck, colorectal or breast cancer experiencing a first episode of moderate to severe pain while attending one of the participating centres. QoL was assessed using the EuroQol-5D questionnaire and pain using the Brief Pain Inventory (BPI). Instruments were administered at baseline and after 3 months of follow up. Multivariate analyses were used to assess the impact of treatment factors, demographic and clinical variables, pain and other symptoms on QoL scores. 1711 patients were included for analysis. After 3 months of usual care, a significant improvement was observed in pain and QoL in all four cancer groups (p<0.001). Effect sizes were medium to large on the BPI and EQ-5D Index and Visual Analogue Scale (VAS). Improvements were seen on the majority of EQ-5D dimensions in all patient groups, though breast cancer patients showed the largest gains. Poorer baseline performance status (ECOG) and the presence of anxiety/depression were associated with significantly poorer QOL outcomes. Improvements in BPI pain scores were associated with improved QoL. In the four cancer types studied, pain and QoL outcomes improved considerably after 3 months of usual care. Improvements in pain made a substantial contribution to QoL gains whilst the presence of anxiety and depression and poor baseline performance status significantly constrained improvement.

The purpose of this study was to determine if schizoaffective disorder in older adults is differentiated from schizophrenia and bipolar disorder with respect to community functioning, cognitive functioning, psychiatric symptoms, and service use. Secondary analysis of baseline data collected from the Helping Older People Experience Success psychosocial skills training and health management study. Three community mental health centers in New Hampshire and Massachusetts. Adults over the age of 50 (N = 139, mean age: 59.7 years, SD: 7.4 years) with persistent functional impairment and a diagnosis of schizoaffective disorder (N = 52), schizophrenia (N = 51), or bipolar disorder (N = 36). Health status (36-Item Short Form Health Survey [SF-36]), performance-based community living skills (UCSD Performance-Based Skills Assessment), neuropsychological functioning (Delis-Kaplan Executive Functioning subtests), psychiatric symptoms (Brief Psychiatric Rating Scale, Center for Epidemiologic Studies Depression Scale, Scale for the Assessment of Negative Symptoms), medical severity (Charlson comorbidity index), and acute service use. Older adults with schizoaffective disorder had depressive symptoms of similar severity to bipolar disorder, and thought disorder symptoms of similar severity to schizophrenia. Schizoaffective disorder compared with schizophrenia was associated with better community functioning, but poorer subjective physical and mental health functioning as measured by the SF-36. Older adults with schizoaffective disorder had greater acute hospitalization compared with adults with schizophrenia, though their use of acute care services was comparable to individuals with bipolar disorder. Findings from this study suggest that schizoaffective disorder in older adults occupies a distinct profile from either schizophrenia or bipolar disorder with respect to community functional status, symptom profile, and acute services utilization.

Quantile Regression Models for Current Status Data

Ou, Fang-Shu; Zeng, Donglin; Cai, Jianwen

2016-01-01

Current status data arise frequently in demography, epidemiology, and econometrics where the exact failure time cannot be determined but is only known to have occurred before or after a known observation time. We propose a quantile regression model to analyze current status data, because it does not require distributional assumptions and the coefficients can be interpreted as direct regression effects on the distribution of failure time in the original time scale. Our model assumes that the conditional quantile of failure time is a linear function of covariates. We assume conditional independence between the failure time and observation time. An M-estimator is developed for parameter estimation which is computed using the concave-convex procedure and its confidence intervals are constructed using a subsampling method. Asymptotic properties for the estimator are derived and proven using modern empirical process theory. The small sample performance of the proposed method is demonstrated via simulation studies. Finally, we apply the proposed method to analyze data from the Mayo Clinic Study of Aging. PMID:27994307

This study was conducted to evaluate the effect of aromatherapy massage on knee pain and functional status in subjects with osteoarthritis. The study was designed as a non-randomized interventional study. The study was carried out on patients who referred to the outpatient clinics of the Department of Orthopedics, Physiotherapy and Rehabilitation at Bozok University Research and Application Hospital, and were diagnosed with osteoarthritis. A total number of 95 patients were included in the study, and of those, 33 were allocated to aromatherapy massage group, 30 were allocated to conventional massage group, and 32 were allocated to the control group. The study data were collected using the Patient Identification Form, visual analogue scale, the Western Ontario and McMaster University Osteoarthritis Index. Repeated measures analysis of variance test was used to analyze the outcomes in the aromatherapy, conventional massage and control groups, according to the weeks of follow-up. Bonferroni test was used for further analysis. Baseline mean visual analogue scale score and the Western Ontario and McMaster University Osteoarthritis Index were not significantly different between the groups (p > .05). Visual analogue scale (rest-activity) scores and the scores in the Western Ontario and McMaster University Osteoarthritis Index in the aromatherapy massage group were lower, and the difference compared to the control group was statistically significant (p < .001). Aromatherapy massage performed in patients with osteoarthritis reduced knee pain scores, decreased morning stiffness, and improved physical functioning status. Thus, as long as specific training is provided for aromatherapy massage, aromatherapy can be recommended for routine use in physical therapy units, hospitals and homes.

Where conservation resources are limited and conservation targets are diverse, robust yet flexible priority-setting frameworks are vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial and temporal scales. Marine turtles are widely distributed and exhibit intra-specific variations in population sizes and trends, as well as reproduction and morphology. However, current global extinction risk assessment frameworks do not assess conservation status of spatially and biologically distinct marine turtle Regional Management Units (RMUs), and thus do not capture variations in population trends, impacts of threats, or necessary conservation actions across individual populations. To address this issue, we developed a new assessment framework that allowed us to evaluate, compare and organize marine turtle RMUs according to status and threats criteria. Because conservation priorities can vary widely (i.e. from avoiding imminent extinction to maintaining long-term monitoring efforts) we developed a “conservation priorities portfolio” system using categories of paired risk and threats scores for all RMUs (n = 58). We performed these assessments and rankings globally, by species, by ocean basin, and by recognized geopolitical bodies to identify patterns in risk, threats, and data gaps at different scales. This process resulted in characterization of risk and threats to all marine turtle RMUs, including identification of the world's 11 most endangered marine turtle RMUs based on highest risk and threats scores. This system also highlighted important gaps in available information that is crucial for accurate conservation assessments. Overall, this priority-setting framework can provide guidance for research and conservation priorities at multiple relevant scales, and should serve as a model for conservation status assessments and priority-setting for widespread, long-lived taxa.

To evaluate the short- and long-term orthodontic treatment (OT) expectations, malocclusion severity, and oral health-related quality of life (OHRQoL) status of adolescent patients using qualitative and quantitative methodology. Adolescents (n = 105; 42 males and 63 females) aged between 12 and 17 years participated in this interview and questionnaire-based study. The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and the Oral Impacts on Daily Performances (OIDP) scale evaluated OHRQoL status. Study casts were analysed using the Dental Aesthetics Index (DAI) and the Index of Complexity, Outcome and Need (ICON). Mann-Whitney test and Spearman's correlations tested various univariate variables. With similar index-determined OT need (DAI, P = 0.371 and ICON, P = 0.932) females tended to have worse OHRQoL status (PIDAQ scores, P-values ranged from 0.006 to 0.0001 and scores for the OIDP question related to smiling, laughing, and showing teeth without embarrassment, P-value = 0.015). Occlusal index scores did not have statistically significant associations with the OHRQoL scales. Better dental appearance was expected by 85 per cent of the adolescents in the short-term and by 51 per cent in the long-term after OT. The associated psycho-social expectations were: 1. improved dental self-confidence, 2. positive psychological impact/improved self-worth, and 3. positive social impact. Female adolescent patients tended to experience worse psycho-social impacts related to their malocclusions compared with males with similar index-determined OT need. Index-determined OT need scores did not correlate with the OHRQoL scales. Adolescent patients expected OT to improve their dental appearance and QoL aspects. © The Author 2015.

To compare the psychometric properties of three cigarette withdrawal scales. An internet cohort study. Each of 4,644 current (44%), former (49%) and never smokers (7%) completed the three scales via the internet. A subsample completed the scales again after 14 days (n=1309), and indicated their smoking status after 42 days (n=1431). The Cigarette Withdrawal Scale (CWS), the Wisconsin Withdrawal Scale (WWS) and the Minnesota Withdrawal Form (MWF). All three scales covered the main elements in the Diagnostic and Statistical Manual version IV (DSM-IV) and the International Classification of Diseases version 10 (ICD-10) definitions of tobacco withdrawal, but WWS did not cover weight gain. Factor analyses indicated that only six factors were present in WWS, instead of the expected seven factors. Cronbach's alpha coefficients (0.76-0.93) were high for all scales. Test-retest coefficients were in the range of 0.66-0.86 for CWS and WWS, but were somewhat lower for some MWF items (range 0.52-0.80). In 324 ex-smokers who had quit smoking 31 days or less before baseline, craving predicted relapse at 14-day follow-up (CWS: odds ratio=1.53 per point, P=0.003; WWS: odds ratio=1.40, P=0.04; MWF: odds ratio=1.49, P=0.002). In 34 baseline smokers who had quit smoking by 14-day retest, an increase in craving (WWS and MWF), depressed mood (MWF) and difficulty concentrating (WWS) between baseline and retest predicted relapse at 42-day follow-up. In terms of construct validity, scales performed similarly, but performance on some key tests (e.g. withdrawal will increase post-cessation) were inadequate, due perhaps to methodological limitations. No scale showed a decisive advantage over the others. MWF has the advantage of brevity.

Convulsive status epilepticus is a common neurologic emergency in pediatrics. We aimed to study the etiology, clinical features, and prognostic factors among pediatric patients with convulsive status epilepticus. Seventy patients were included in this cohort study from pediatric emergency department of the specialized Children Hospital of Cairo University. The outcome was evaluated using the Glasgow Outcome Score. Acute symptomatic etiology was the most common cause of convulsive status epilepticus. Refractory convulsive status epilepticus was observed more significantly in cases caused by acute symptomatic etiologies. The outcome was mortality in 26 (37.1%) patients, severe disability in 15 (21.4%), moderate disability in 17 (24.3%), and good recovery in 12 (17.1%) patients. The significant predictor of mortality was lower modified Glasgow Coma Scale score on admission, whereas lower modified Glasgow Coma Scale score on admission and refractory convulsive status epilepticus were the significant predictors for disability and mortality. © The Author(s) 2015.

The purpose of this exploratory study was to examine four manifestations of human-environmental field patterning--human field motion, human field rhythms, creativity, and sentience--in relation to perceived health status in 106 early, 111 middle, and 113 late adolescents. Participants responded to the Perceived Field Motion Instrument (a measure of human field motion), the Human Field Rhythms Scale, the Sentience Scale, the General Health Rating Index (a measure of perceived health status), and a brief demographic data sheet in classroom settings. Data were analyzed using Pearson correlations. Statistically significant positive correlations were found between perceived field motion and perceived health status in early, middle, and late adolescents, between human field rhythms and perceived health status in late adolescents only, and between creativity and perceived health status in late adolescents only. The inverse relationship found between sentience and perceived health status in early, middle, and late adolescents was not statistically significant. The findings are interpreted within a Rogerian framework.

We conducted a cross-sectional study on 193 mothers of children 6 to 18 months of age in an African-Colombian community, with the objectives: (1) to adapt and validate the Community Childhood Hunger Identification Project scale, the DUKE-UNC-11 social support scale, and the Quebec Longitudinal Study of Child Development (QLSCD) partner support scale, and (2) to identify any existent relationship between nutritional status in infancy and both food insecurity and social support. We determined construct validity using factor analysis and theoretical models-based non-parametric correlations. Length-for-age and weight-for-length Z-results were calculated. Factor analyses reduced the hunger scale to one factor, the DUKE-UNC-11 scale to two factors, and the QLSCD scale to one factor. The Cronbach's alpha test ranged between 0.70 and 0.90. Both food insecurity and social support scales were correlated with mother's social conditions, and social support was positively associated with social networks and mother's self-perceived health status. Food insecurity, emotional-social support, and partner's negative support were associated with lower height-to-age and therefore a higher ratio of chronic malnutrition. The study supports the appropriateness of the instruments to measure the expressed concepts.

Our objectives were: (a) to identify predictors of change in health-related quality of life (HRQOL) in patients with advanced non-small cell lung cancer (NSCLC) undergoing chemotherapy; and (b) to characterize symptom status, nutritional status, physical performance and HRQOL in this population and to estimate the extent to which these variables change following two cycles of chemotherapy. A secondary analysis of a longitudinal observational study of 47 patients (24 men and 23 women) with newly diagnosed advanced NSCLC receiving two cycles of first-line chemotherapy was performed. Primary outcomes were changes in HRQOL (physical and mental component summaries (PCS and MCS) of the 36-item Short-Form Health Survey (SF-36)). Predictors in the models included pre-chemotherapy patient-reported symptoms (Schwartz Cancer Fatigue Scale (SCFS) and Lung Cancer Subscale), nutritional screening (Patient-Generated Subjective Global Assessment) and physical performance measures (6-min Walk Test (6MWT), one-minute chair rise test and grip strength). Mean SF-36 PCS score, 6MWT distance and grip strength declined following two cycles of chemotherapy (p<0.05). Multiple linear regression modelling revealed pre-chemotherapy SCFS score and 6MWT distance as the strongest predictors of change in the mental component of HRQOL accounting for 13% and 9% of the variance, respectively. No significant predictors were found for change in the physical component of HRQOL. Pre-chemotherapy 6MWT distance and fatigue severity predicted change in the mental component of HRQOL in patients with advanced NSCLC undergoing chemotherapy, while physical performance declined during treatment. Clinical management of these factors may be useful for HRQOL optimization in this population. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To examine in a sample of hematopoietic stem cell transplant patients assessed throughout protective isolation (i) levels of anxiety and depression and (ii) pre-isolation factors (socio-demographics, biomedical variables and personality traits), which might predict higher levels of anxiety and depression during isolation. The study used a longitudinal prospective design. Anxiety and depression were assessed in 107 participants by the State-Trait Anxiety Inventory and Self-rating Depression Scale at admission and weekly at fixed time points throughout isolation. Among pre-isolation factors, patients' psychological status was evaluated by the Cognitive Behavioral Assessment (2.0). Predictors were explored by random-effects models. One-tenth of the patients suffered from clinically significant anxiety and depressive symptoms at admission. Although the percentage of depressed patients increased more than twofold after 2 weeks of isolation, that of anxious patients did not significantly change over time. Female gender, higher anxiety and obsessive-compulsive symptoms, intratensive personality traits and lower performance status predicted higher depression during isolation. Anxiety and depression represent a relevant problem for hematopoietic stem cell transplant patients during isolation. Early detection of predictors, such as anxiety levels, obsessive-compulsive symptoms and performance status, could help prevent depression via targeted psychological intervention.

Centenarians represent a rare but rapidly growing segment of the oldest-old. This study presents item-level data from the Mini-Mental State Examination (MMSE, M=16.2, SD=8.8, Range 0–30) in a cross-sectional, population-based sample of 244 centenarians and near-centenarians (aged 98–108, 16% men, 21% African-American, 38% community-dwelling) from the Georgia Centenarian Study (2001–2008) by age, education, sex, race, and residential status. Multiple-Indicator Multiple-Causes (MIMIC) models were used to identify systematic domain-level differences on MMSE scores by key demographic characteristics in this age group. Indirect effects of age, educational attainment, race, and residential status were found on MMSE scores. Direct effects were limited to concentration for education and race, and orientation for residential status. Mean levels of cognitive functioning in centenarians were low, with mean values below most commonly-used cut-offs. Overall scores on the MMSE differed as a function of age, education, race, and residential status, with differences in scale performance limited primarily to concentration and orientation, with no evidence for interactions among centenarian characteristics. Adjusting for education was not sufficient to account for differences by race; adjusting for residential status was not sufficient to account for differences by age. PMID:23889552

To investigate 6-year-old to 8-year-old children's health, nutritional status and cognitive development in a predominantly rural area of KwaZulu-Natal, South Africa. Cohort study of 1383 children investigating the association of demographic variables (area of residence, sex, pre-school education, HIV status, height for age and haemoglobin level) and family variables (socioeconomic status, maternal and paternal level of education), with children's cognitive performance. The latter was measured using the Grover-Counter Scale of Cognitive Development and subtests of the Kaufman Assessment Battery for Children, second edition (KABC-II). General linear models were used to determine the effect of these predictors. Area of residence and height-for-age were the statistically significant factors affecting cognitive test scores, regardless of attending pre-school. Paternal level of education was also significantly associated with the cognitive test scores of the children for all three cognitive test results, whereas HIV status, sex and their socioeconomic status were not. Children with low cognitive scores tended to be stunted (low height-for-age scores), lacked pre-school education and were younger. Area of residence and their parents' educational level also influenced their cognition. © 2017 John Wiley & Sons Ltd.

Strong scientific evidence supports voluntary medical male circumcision as part of an overall HIV prevention strategy, but self-report information on circumcision status may be inaccurate. The study objectives were to obtain estimates of male circumcision within the Rwanda Defense Force (RDF), to assess the ability of soldiers to correctly report their own circumcision status, and to document the uptake of voluntary medical male circumcision (VMMC) in the RDF. Data were collected from members of the Rwandan military during their annual physical examination. A self-administered questionnaire collected demographic and circumcision characteristics. Self-reported circumcision status was compared with the medical exam evaluation. Using questionnaires with complete data (n = 579), 69% of the study participants were circumcised by physical examination and there was a strong agreement with self-reported circumcision status (κ = 0.97). Almost half (44%) of all circumcisions had been performed within the past 2 years. These results suggest that self-report is an appropriate method to collect information on circumcision status in the Rwandan military. Many of the circumcisions occurred within the last 2 years, possibly as an effect of the successful scale-up of voluntary medical male circumcision in the Rwandan military utilizing effective messaging, demand creation, and positive news reported by the media.

We examined the relationship between return to work (RTW) from sick leave (SL) and personality traits in workers with major depressive disorder (MDD). Eighty-eight Japanese individuals with ≥2 weeks of SL episode and with ≥2 months of pharmacotherapy history were assessed. Measurements included Mini-International Neuropsychiatric Interview (MINI), Hamilton Rating Scale for Depression (HAM-D), Neuroticism, and Interpersonal Sensitivity Measure (IPSM). Multivariate analyses were conducted to clarify the association between personality traits and RTW status. In order to minimize the state effect of depressive symptoms to personality traits, we performed an additional analysis among a subgroup of subjects in remission (HAM-D ≤7). Thirty-seven subjects (42.0%) had returned to work. Among whole subjects, factors associated with RTW status were: shorter SL duration in the past 5 years, longer treatment duration of the recent major depressive episode, HAM-D ≤7, and IPSM ≤94. In the subgroup of remission subjects (n=53), factors associated with RTW status were: IPSM ≤94, no comorbid current anxiety disorder, and shorter SL duration in the past 5 years. Low interpersonal sensitivity, along with depression remission, was associated with post-SL RTW status among workers with MDD. Copyright © 2012 Elsevier B.V. All rights reserved.

Background This study examined the association between immigrant status and current health in a representative sample of 1,189 homeless people in Toronto, Canada. Methods Multivariate regression analyses were performed to examine the relationship between immigrant status and current health status (assessed using the SF-12) among homeless recent immigrants (≤10 years since immigration), non-recent immigrants (>10 years since immigration), and Canadian-born individuals recruited at shelters and meal programs (response rate 73%). Results After adjusting for demographic characteristics and lifetime duration of homelessness, recent immigrants were significantly less likely to have chronic conditions (RR 0.7, 95% CI 0.5 to 0.9), mental health problems (OR 0.4, 95% CI 0.2 to 0.7), alcohol problems (OR 0.2, 95% CI 0.1 to 0.5), and drug problems (OR 0.2, 95% CI 0.1 to 0.4) compared to non-recent immigrants and Canadian-born individuals. Recent immigrants were also more likely to have better mental health status (+3.4 points, SE ±1.6) and physical health status (+2.2 points, SE ±1.3) on scales with a mean of 50 and a standard deviation of 10 in the general population. Conclusion Homeless recent immigrants are a distinct group who are generally healthier and may have very different service needs compared to other homeless people. PMID:19654122

Obstructive sleep apnea (OSA) is a common sleep disorder in stroke patients and is associated with prolonged hospitalization, decreased functional outcome, and recurrent stroke. Research on the effect of OSA on cognitive functioning following stroke is scarce. The primary objective of this study was to compare stroke patients with and without OSA on cognitive and functional status upon admission to inpatient rehabilitation. Case-control study. 147 stroke patients admitted to a neurorehabilitation unit. N/A. All patients underwent sleep examination for diagnosis of OSA. We assessed cognitive status by neuropsychological examination and functional status by two neurological scales and a measure of functional independence. We included 80 stroke patients with OSA and 67 stroke patients without OSA. OSA patients were older and had a higher body mass index than patients without OSA. OSA patients performed worse on tests of attention, executive functioning, visuoperception, psychomotor ability, and intelligence than those without OSA. No differences were found for vigilance, memory, and language. OSA patients had a worse neurological status, lower functional independence scores, and a longer period of hospitalization in the neurorehabilitation unit than the patients without OSA. OSA status was not associated with stroke type or classification. Obstructive sleep apnea (OSA) is associated with a lower cognitive and functional status in patients admitted for stroke rehabilitation. This underlines the importance of OSA as a probable prognostic factor, and calls for well-designed randomized controlled trials to study its treatability. © 2015 Associated Professional Sleep Societies, LLC.

Comparison among various methods of assessment of impulsiveness.

The current confused status of the research on impulsivity may be attributed to the lack of precise definitions, the reliance of most operationalizations on a single index, and inconsistency among different measures of the construct. Empirical measurements of impulsivity by self-reports, rating scales, or performance tasks suggest that the instruments employed measure aspects that have very little in common, a finding that throws serious doubts on the validity of the construct and implies a need for further research. To clarify this topic, we applied four different measures of impulsivity to 46 7th-grade (12 to 13 years old) schoolchildren. The children were rated by their teachers on an impulsivity behavior scale and were administered Kagan's Matching Familiar Figures Test, Version MFF-20, and two self-report forms, the Eysenck Impulsiveness Questionnaire, and the Barratt Impulsiveness Scale. Although the results confirmed the lack of convergence among these measures, high latencies on matching were associated with the cognitive aspect of the self-report scales. Treating impulsivity as a multidimensional construct is discussed.

Tibiotalocalcaneal (TTC) fusion using a retrograde intramedullary (IM) nail is an effective salvage option for terminal-stage hindfoot problems. However, as many patients who receive TTC fusion bear unfavorable medical comorbidities, the risk of nonunion, infection and other complications increases. This study was performed to identify the factors influencing outcomes after TTC fusion using a retrograde IM nail. Between September 2008 and February 2012, 34 consecutive patients received TTC fusion using a retrograde IM nail for limb salvage. All patients had a minimum follow-up of two years. Throughout follow-up, standard ankle radiography was performed along with clinical outcome assessment using a visual analog scale (VAS) for pain, the American Orthopaedic Foot and Ankle Society Ankle-Hind Foot Scale (AOFAS A/H scale) and the Foot and Ankle Outcome Score (FAOS). For the retrospective analysis, demographic factors, preoperative medical status, laboratory markers, and etiology were comprehensively reviewed using medical records. The success of the index operation was determined using clinical and radiological outcomes. Finally, the effect of each factor on failure after the operation was analyzed using univariate logistic regression. In a mean of seven months, 82% (28/34) achieved union, as evaluated by standard radiography. All clinical outcome parameters improved significantly after the operation, including VAS, AOFAS A/H scale, and FAOS (P<0.001). At the last follow-up, five cases of nonunion with less than AOFAS A/H scale of 80 and two cases of below knee amputation due to uncontrolled infection were determined to be failures. None of the factors (etiology, demographics, laboratory markers and medical status) significantly influenced failures. However, uncontrolled DM significantly increased the failure rate with an odds ratio of 10 (P=0.029). TTC fusion with a retrograde intramedullary nail is a successful treatment for complicated hindfoot problems such as traumatic osteoarthritis, Charcot arthropathy and failed TAA. However, it should be used judiciously in patients with uncontrolled DM, as the risk of failure increases. Retrospective cohort study. Copyright © 2017 European Foot and Ankle Society.

Social status determines how we monitor and evaluate our performance

Since people with low status are more likely to experience social evaluative threat and are therefore more inclined to monitor for these threats and inhibit approach behaviour, we expected that low-status subjects would be more engaged in evaluating their own performance, compared with high-status subjects. We created a highly salient social hierarchy based on the performance of a simple time estimation task. Subjects could achieve high, middle or low status while performing this task simultaneously with other two players who were either higher or lower in status. Subjects received feedback on their own performance, as well as on the performance of the other two players simultaneously. Electroencephalography (EEG) was recorded from all three participants. The results showed that medial frontal negativity (an event-related potential reflecting performance evaluation) was significantly enhanced for low-status subjects. Implications for status-related differences in goal-directed behaviour are discussed. PMID:21421733

To explore the association between MMORPG addiction and mental health status, and between self-control ability and mental health status among young male MMORPG players in Hanoi, Vietnam. In this cross-sectional study, 10 computer game rooms were randomly selected out of 77 in five communes in Hanoi. From these game rooms, 350 MMORPG players were purposively recruited as a study group, of whom 344 completed the questionnaire. In the same five communes, 344 non-players were selected as a control group. An online game addiction scale, a self-control scale and the Vietnamese SRQ-20 were used to measure the degree of MMORPG addiction, self-control ability and level of mental disorders. MMORPG players had significantly higher mental disorders scale scores than non-players (p < .001). The strongest positive correlation was detected between MMORPG addiction scale scores and mental disorders scale scores (r = 0.730, p < .001). Self-control scale scores were negatively associated with mental disorders scale scores (r = -0.345, p < .001). The average amount of money spent on games per month, MMORPG addiction scale score and self-control scale score were considered the best predictors of a higher mental disorders scale score. Young, male MMORPG players with higher addiction scores were more likely to have higher mental disorders scale scores, and such mental status was negatively associated with the level of self-control in Hanoi, Vietnam. Closer attention should be paid to prevent mental disorders among MMORPG players.

There are limited data on illness understanding and perception of cure among advanced cancer patients around the world. The aim of the study was to determine the frequency and factors associated with inaccurate perception of curability among advanced cancer patients receiving palliative care across the globe. Secondary analysis of a study to understand the core concepts in end-of-life care among advanced cancer patients receiving palliative care from 11 countries across the world. Advanced cancer patients were surveyed using a Patient Illness Understanding survey and Control Preference Scale. Descriptive statistics and multicovariate logistic regression analysis were performed. Fifty-five percent (763/1,390) of patients receiving palliative care inaccurately reported that their cancer is curable. The median age was 58, 55% were female, 59% were married or had a partner, 48% were Catholic, and 35% were college educated. Sixty-eight percent perceived that the goal of therapy was "to get rid of their cancer," and 47% perceived themselves as "seriously ill." Multicovariate logistic regression analysis shows that accurate perception of curability was associated with female gender (odds ratio [OR] 0.73, p  = .027), higher education (OR 0.37, p  < .0001), unemployment status (OR 0.69, p  = .02), and being from France (OR 0.26, p  < .0001) and South Africa (OR 0.52, p  = .034); inaccurate perception of curability was associated with better Karnofsky performance status (OR 1.02 per point, p  = .0005), and being from Philippines (OR 15.49, p  < .0001), Jordan (OR 8.43, p  < .0001), Brazil (OR 2.17, p  = .0037), and India (OR 2.47, p  = .039). Inaccurate perception of curability in advanced cancer patients is 55% and significantly differs by gender, education, performance status, employment status, and country of origin. Further studies are needed to develop strategies to reduce this misperception of curability in advanced cancer patients. The findings of this study indicate that inaccurate perception of curability among advanced cancer patients is 55%. Inaccurate perception of curability significantly differs by gender, education, performance status, employment status, and country of origin. There is great need to facilitate improved patient-physician communication so as to improve health care outcomes and patient satisfaction. © AlphaMed Press 2017.

Effects of demographic and health variables on Rasch scaled cognitive scores.

To determine whether demographic and health variables interact to predict cognitive scores in Asset and Health Dynamics of the Oldest-Old (AHEAD), a representative survey of older Americans, as a test of the developmental discontinuity hypothesis. Rasch modeling procedures were used to rescale cognitive measures into interval scores, equating scales across measures, making it possible to compare predictor effects directly. Rasch scaling also reduces the likelihood of obtaining spurious interactions. Tasks included combined immediate and delayed recall, the Telephone Interview for Cognitive Status (TICS), Series 7, and an overall cognitive score. Demographic variables most strongly predicted performance on all scores, with health variables having smaller effects. Age interacted with both demographic and health variables, but patterns of effects varied. Demographic variables have strong effects on cognition. The developmental discontinuity hypothesis that health variables have stronger effects than demographic ones on cognition in older adults was not supported.

The aims of this study were to determine the prevalence of osteosarcopenic obesity (OSO) and to investigate its association with frailty and physical performance in Mexican community-dwelling middle-aged and older women. Cross-sectional analysis of a prospective cohort. The FraDySMex study, a 2-round evaluation of community-dwelling adults from 2 municipalities in Mexico City. Participants were 434 women aged 50 years or older, living in the designated area in Mexico City. Body composition was measured with dual-energy X-ray absorptiometry and OSO was defined by the coexistence of sarcopenia, osteopenia, or osteoporosis and obesity. Information regarding demographic characteristics; comorbidities; mental status; nutritional status; and history of falls, fractures, and hospitalization was obtained from questionnaires. Objective measurements of muscle strength and function were grip strength using a hand dynamometer, 6-meter gait speed using a GAIT Rite instrumented walkway, and lower extremity functioning measured by the Short Physical Performance Battery (SPPB). Frailty was assessed using the Frailty Phenotype (Fried criteria), the Gerontopole Frailty Screening Tool (GFST), and the FRAIL scale, to build 3 logistic regression models. The prevalence of OSO was 19% (n = 81). Frailty (according to the Frailty Phenotype and the GFST) and poor physical performance measured by the SPPB were independently associated with OSO, controlled by age. In the logistic regression model assessing frailty with the Frailty Phenotype, the odds ratio (95% confidence interval) for frailty was 4.86 (2.47-9.55), and for poor physical performance it was 2.11 (1.15-3.89). In the model assessing frailty with the GFST, it was 2.12 (1.10-4.11), and for poor physical performance it was 2.15 (1.18-3.92). Finally, in the model with the FRAIL scale, it was 1.69 (0.85-3.36) for frailty and 2.29 (1.27-4.15) for poor physical performance. OSO is a frequent condition in middle-aged and older women, and it is independently associated with frailty and poor physical performance.

Land Management, River Restoration and the Water Framework Directive

Smith, Ben; Clifford, Nicholas

2014-05-01

The influence of catchment land-use on river ecosystems is well established, with negative changes in hydrology, sediment supply and pollutants causing widespread degradation in modified catchments across Europe. The strength of relationship found between different land-use types and impacts on river systems varies from study to study as a result of issues around data quality, scale, study design and the interaction of stressors at multiple scales. Analysis of large-scale datasets can provide important information about the way that catchments pressures affect WFD objectives at a national scale. Comparisons of relationships between land-use and WFD status in different types of catchment within the UK allow an assessment of catchment sensitivity and analysis of the catchment characteristics which influence these relationships. The results suggest prioritising catchments at or near land-use thresholds, or targeting waterbodies with limited land-use pressures but which are failing to achieve GES or GEP. This paper uses UK datasets on land cover and WFD waterbody status to examine how catchment land-use impacts on WFD status and to evaluate opportunities to achieve Good Ecological Status or Good Ecological Potential. Agricultural and urban land-use are shown to have different types of relationship with respect to the likelihood of achieving Good Ecological Status, and with clear threshold effects apparent for urban land-use in the catchment. Broad-scale analysis shows the influence of different sized buffer strips in mitigating the negative effects of different types of land-cover, and reinforces the positive effects of riparian woodland on river ecosystems and their potential under the WFD.

This study investigated the effect of Ethnoscience instruction and moderating effects of school location and parental educational status on students' attitude to science. It employed pretest-posttest, non-equivalent control group quasiexperimental design. Participants were 352 Junior Secondary School 1 (aged 9-12 years) students from two schools, each in urban and rural areas of Ìbàdàn, southwestern Nigeria. Instruments used are: Teachers Instructional Guide on Ethnoscience instruction, Teachers Instructional Guide on Modified Lecture Method and Attitude Toward Science Scale (r = 0.86). Three null hypotheses were tested at 0.05 level of significance. Data were analyzed using Analysis of Covariance. Significant main effect of treatment on attitude to science (F(1, 347) = 296, p < 0.05) was recorded, with Ethnoscience instruction group performing better than the Modified Lecture Method group. Effect size of treatment was strong (η2 p = 0.46). Also recorded were significant main effects of school location (F(1, 347) = 10.2, p < .05) and parental educational status (F(1, 347 = 3.37), p < 0.05) on students' attitude to science with weak effect sizes (η2 p = 0.029 and η2 p = 0.019 respectively). Learners in rural schools performed better than those in urban schools and those from lowly educated parents had better performance than highly educated parents. Ethnoscience instruction promoted learners' attitude to science. Therefore, its use in educational instruction, especially among traditional science learners, should be explored.

2016-03-01

Background: Lung-RADS is the new oncology classification guideline proposed by American College of Radiology (ACR), which provides recommendation for further follow up in lung cancer screening. However, only two features (solidity and size) are included in this system. We hypothesize that additional sematic features can be used to better characterize lung nodules and diagnose cancer. Objective: We propose to develop and characterize a systematic methodology based on semantic image traits to more accurately predict occurrence of cancerous nodules. Methods: 24 radiological image traits were systematically scored on a point scale (up to 5) by a trained radiologist, and lung-RADS was independently scored. A linear discriminant model was used on the semantic features to access their performance in predicting cancer status. The semantic predictors were then compared to lung-RADS classification in 199 patients (60 cancers, 139 normal controls) obtained from the National Lung Screening Trial. Result: There were different combinations of semantic features that were strong predictors of cancer status. Of these, contour, border definition, size, solidity, focal emphysema, focal fibrosis and location emerged as top candidates. The performance of two semantic features (short axial diameter and contour) had an AUC of 0.945, and was comparable to that of lung-RADS (AUC: 0.871). Conclusion: We propose that a semantics-based discrimination approach may act as a complement to the lung-RADS to predict cancer status.

This study aimed to examine whether Sjögren syndrome (SS) is related to periodontal status. A systematic review was performed on the basis of PRISMA (PROSPERO: CRD42017055202). A search was performed in the PubMed/MEDLINE, LILACS, Web of Science, and Science Direct databases. Hand searches and review of the gray literature were also performed. Three researchers independently selected studies, extracted data, and assessed methodologic quality. Studies that correlated primary and/or secondary SS with plaque index, gingival index, probing depth, and bleeding on probing were included. The risk of bias was estimated on the basis of the Newcastle-Ottawa scale. Seventeen studies were included in the review and 9 included in the meta-analysis, with a total of 518 and 544 patients, with or without SS, respectively. The mean difference of plaque index (0.29; 95% confidence interval [CI] 0.17-0.41), gingival index (0.52; 95% CI 0.14-0.89), and bleeding on probing (9.92; 95% CI 4.37-15.47) were larger in patients with SS than in controls. In primary SS (0.47; 95% CI 0.10-0.83) and secondary SS (0.74; 95% CI 0.10-1.38), only the mean gingival index was larger compared with that in control group. The majority of the included studies were judged as having a high risk of bias. The present review did not provide strong evidence that periodontal status is affected by SS.

The objective of this study was to examine the sensitivity and specificity of a performance-based measure of functional capacity, the UCSD Performance-Based Skills Assessment (UPSA) for the prediction of independent living status in patients with chronic schizophrenia-related conditions. A sample of 434 adults with schizophrenia or schizoaffective disorder was administered the UPSA and assessed for independent living status. Participants were classified as “independent” if they were living alone in an apartment, house, or single-resident occupancy (e.g., hotel room) and non-independent if they resided in a care facility (e.g., Board-and-Care home, Skilled Nursing Facility). Receiver Operator Characteristic (ROC) curves were calculated with the UPSA and Mattis’ Dementia Rating Scale (DRS) scores as predictor variables and residential independence as the state variable. Of the 434 participants, 99 (23%) were living independently at the time of assessment. The discriminant validity of the UPSA was adequate (ROC area under the curve = 0.74; 95% CI: 0.68–0.79), with greatest dichotomization for the UPSA at a cutoff score of 75 (68% accuracy, 69% sensitivity, 66% specificity), or 80 (68% accuracy, 59% sensitivity, 76% specificity). The UPSA was also a significantly better predictor of living status than was the DRS, based on ROC (z = 2.43, p = .015). The UPSA is a brief measure of functional capacity that predicts the ability of patients with schizophrenia to reside independently in the community. PMID:17303168

Cognitive complaints occur frequently in elderly people and may be a risk factor for dementia and cognitive decline. Results from studies on subjective cognitive decline are difficult to compare due to variability in assessment methods, and little is known about how different methods influence reports of cognitive decline. The Subjective Memory Complaints Scale (SMC) and The Memory Complaint Questionnaire (MAC-Q) were applied in 121 mixed memory clinic patients with mild cognitive symptoms (mean MMSE = 26.8, SD 2.7). The scales were applied independently and raters were blinded to results from the other scale. Scales were not used for diagnostic classification. Cognitive performances and depressive symptoms were also rated. We studied the association between the two measures and investigated the scales' relation to depressive symptoms, age, and cognitive status. SMC and MAC-Q were significantly associated (r = 0.44, N = 121, p = 0.015) and both scales had a wide range of scores. In this mixed cohort of patients, younger age was associated with higher SMC scores. There were no significant correlations between cognitive test performances and scales measuring subjective decline. Depression scores were significantly correlated to both scales measuring subjective decline. Linear regression models showed that age did not have a significant contribution to the variance in subjective memory beyond that of depressive symptoms. Measures for subjective cognitive decline are not interchangeable when used in memory clinics and the application of different scales in previous studies is an important factor as to why studies show variability in the association between subjective cognitive decline and background data and/or clinical results. Careful consideration should be taken as to which questions are relevant and have validity when operationalizing subjective cognitive decline.

Pre-pregnancy maladaptive eating behaviors have predicted inadequate or excess gestational weight gain and poor dietary intake during pregnancy, but little is known about effects of pre-pregnancy adaptive eating behaviors on pregnancy outcomes. The purpose of this study was to produce a valid and reliable measure of adaptive pre-pregnancy eating behaviors for pregnant women using the Intuitive Eating Scale. Data were collected from 266 pregnant women, aged 18 and older who were attending a private prenatal clinic at Texas Children's Hospital Pavilion for Women in Houston, TX using self-administered questionnaires. Confirmatory factor analysis was performed to validate the factor structure of the Intuitive Easting Scale (IES). Concurrent validity was determined using correlations between the three subscale scores [unconditional permission to eat (UPE), eating for physical not emotional reasons (EPR), and relying on hunger/satiety cues (RIH)], perinatal depression status (Edinburgh Postnatal Depression Scale), and pre-pregnancy body mass index (BMI) calculated from self-reported height and weight. After discarding 6 items, the second order model did not fit the data, however, the first order model with three latent factors had reasonable fit (RMSEA = 0.097, CFI = 0.961, TLI = 0.951 and WRMR = 1.21). The internal consistency of the scale was confirmed by Cronbach's alphas (UPE = 0.781, EPR = 0.878 and RIH = 0.786). All subscale scores were inversely related to perinatal depression status. EPR and RIH subscale scores were inversely related to pre-pregnancy BMI, supporting the measure's validity. Among pregnant women, the revised 15 item pre-pregnancy IES (IES-PreP) should be used to evaluate pre-pregnancy adaptive eating behaviors. Copyright © 2017 Elsevier Ltd. All rights reserved.

Research suggests that employee status, and various status proxies, relate to a number of meaningful outcomes in the workplace. The advancement of the study of status in organizational settings has, however, been stymied by the lack of a validated workplace status measure. The purpose of this manuscript, therefore, is to develop and validate a measure of workplace status based on a theoretically grounded definition of status in organizations. Subject-matter experts were used to examine the content validity of the measure. Then, 2 separate samples were employed to assess the psychometric properties (i.e., factor structure, reliability, convergent and discriminant validity) and nomological network of a 5-item, self-report Workplace Status Scale (WSS). To allow for methodological flexibility, an additional 3 samples were used to extend the WSS to coworker reports of a focal employee's status, provide additional evidence for the validity and reliability of the WSS, and to demonstrate consensus among coworker ratings. Together, these studies provide evidence of the psychometric soundness of the WSS for assessing employee status using either self-reports or other-source reports. The implications of the development of the WSS for the study of status in organizations are discussed, and suggestions for future research using the new measure are offered.

Self-management of complex medication regimens for chronic illness is challenging for many older adults. The purpose of this study was to evaluate health status outcomes of frail older adults receiving a home-based support program that emphasized self-management of medications using both care coordination and technology. This study used a randomized controlled trial with three arms and longitudinal outcome measurement. Older adults having difficulty in self-managing medications (n = 414) were recruited at discharge from three Medicare-certified home healthcare agencies in a Midwestern urban area. All participants received baseline pharmacy screens. The control group received no further intervention. A team of advanced practice nurses and registered nurses coordinated care for 12 months to two intervention groups who also received either an MD.2 medication-dispensing machine or a medplanner. Health status outcomes (the Geriatric Depression Scale, Mini Mental Status Examination, Physical Performance Test, and SF-36 Physical Component Summary and Mental Component Summary) were measured at baseline and at 3, 6, 9, and 12 months. After covariate and baseline health status adjustment, time × group interactions for the MD.2 and medplanner groups on health status outcomes were not significant. Time × group interactions were significant for the medplanner and control group comparisons. Participants with care coordination had significantly better health status outcomes over time than those in the control group, but addition of the MD.2 machine to nurse care coordination did not result in better health status outcomes.

The early cognitive continuum has been emphasized recently. We sought to characterize the functional and physical aspects of the cognitive continuum in subjects with no cognitive impairment (NCI), subjective cognitive impairment (SCI), nonamnestic (NA-MCI), and amnestic mild cognitive impairment (A-MCI). Furthermore, we identified the potential diagnostic utility of specific functional tasks. A total of 702 participants, aged ≥65 years and defined as NCI, SCI, NA-MCI, and A-MCI according to the original Petersen criteria, were included. They completed the Korean basic (K-ADL) and Instrumental Activities of Daily Living Scales (K-IADL) and the Performance-Oriented Mobility Assessment (POMA). Significant differences were observed between the different cognitive status groups in three items and total scores on the K-ADL, six items and total scores on the K-IADL and POMA. Controlling for confounding factors revealed that subjects from the A-MCI group performed poorly at bathing, shopping, handling money, and the sum of assorted functional items. These findings demonstrated the declining feature of functional and physical performance according to the cognitive continuum, with A-MCI being discriminative with respect to specific functional tasks as compared to milder cognitive statuses. © 2014 S.

To determine the effects of spinal stabilization exercises (SSE) and manual therapy methods on pain, function and quality of life (QoL) levels in individuals with chronic low back pain (CLBP). A total of one-hundred thirteen patients diagnosed as CLBP were enrolled to the study. The patients allocated into Spinal Stabilization group (SG) and manual therapy group (MG), randomly. While SSE performed in SG, soft tissue mobilizations, muscle-energy techniques, joint mobilizations and manipulations were performed in MG. While the severity of pain was assessed with Visual Analog Scale (VAS), Oswestry Disability Index (ODI) and Short Form 36 (SF-36) assessments were performed to evaluate the functional status and QoL, respectively. All assessments were repeated before and after the treatment. Intragroup analyses both treatments were effective in terms of sub parameters of pain, function and life quality (p< 0.05). Inter group analyses, there was more reduction in pain and improvement in functional status in favor of MG (p< 0.05). This study showed that SSE and manual therapy methods have the same effects on QoL, while the manual treatment is more effective on the pain and functional parameters in particular.

The present study investigated the relationship between psychological symptoms and psychosocial function and the role of relevant sociodemographic data and antipsychotic use in the prediction of psychosocial function among multiracial schizophrenia outpatients in Malaysia. A total of 223 participants were recruited in this cross-sectional study conducted from December 2010 to April 2011. Psychological symptoms were assessed using the Positive and Negative Syndrome Scale whilst the psychosocial function was assessed using the Personal and Social Performance scale. Sociodemographic and treatment variables were gathered through interview or review of the medical records. All dimensions of psychosocial functions were inversely correlated with Positive and Negative Syndrome Scale sub-domains. Only the disorganization sub-domain significantly predicts all dimensions of psychosocial function. For social data, body mass index and employment status were significant predictors of all dimensions of psychosocial functions. Typical antipsychotics significantly predict social function negatively as compared to sulpiride (β = -0.152, P = 0.028). We found that the relationship between psychological symptoms and psychosocial functions were relatively consistent with the findings from the Caucasian population. Additionally, disorganization was the only significant predictor of all dimensions of psychosocial functions. This further emphasized the importance of cognition in psychosocial function. The roles of sulpiride, body mass index and employment status as predictors of psychosocial function were also discussed. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

An increasing number of patients are suffering from stress-related symptoms and diagnoses. The purpose of this study was to evaluate the medical yoga treatment in patients with stress-related symptoms and diagnoses in primary health care. A randomized controlled study was performed at a primary health care centre in Sweden from March to June, 2011. Patients were randomly allocated to a control group receiving standard care or a yoga group treated with medical yoga for 1 hour, once a week, over a 12-week period in addition to the standard care. A total of 37 men and women, mean age of 53 ± 12 years were included. General stress level (measured using Perceived Stress Scale (PSS)), burnout (Shirom-Melamed Burnout Questionnaire (SMBQ)), anxiety and depression (Hospital Anxiety and Depression Scale (HADS)), insomnia severity (Insomnia Severity Index (ISI)), pain (visual analogue scale (VAS)), and overall health status (Euro Quality of Life VAS (EQ-VAS)) were measured before and after 12 weeks. Patients assigned to the Yoga group showed significantly greater improvements on measures of general stress level (P < 0.000), anxiety (P < 0.019), and overall health status (P < 0.018) compared to controls. Treatment with medical yoga is effective in reducing levels of stress and anxiety in patients with stress-related symptoms in primary health care.

Micronutrient deficiencies can affect cognitive function. Many young children in low- and middle-income countries have inadequate cobalamin (vitamin B-12) status. The objective was to measure the association of plasma concentrations of folate, cobalamin, total homocysteine, and methylmalonic acid with cognitive performance at 2 occasions, 4 mo apart, in North Indian children aged 12-18 mo. Bayley Scales of Infant Development II were used to assess cognition. In multiple regression models adjusted for several potential confounders, we measured the association between biomarkers for folate and cobalamin status and psychomotor or mental development scores on the day of blood sampling and 4 mo thereafter. Each 2-fold increment in plasma cobalamin concentration was associated with a significant increment in the mental development index score of 1.3 (95% CI: 0.2, 2.4; P = 0.021). Furthermore, each 2-fold increment in homocysteine or methylmalonic acid concentration was associated with a decrement in mental development index score of 2.0 (95% CI: 0.5, 3.4; P = 0.007) or 1.1 (95% CI: 0.3, 1.8; P = 0.004) points, respectively. Plasma folate concentration was significantly and independently associated with mental development index scores only when children with poor cobalamin status were excluded, ie, in those who had cobalamin concentrations below the 25th percentile. None of these markers was associated with psychomotor scores in the multiple regression models. Cobalamin and folate status showed a statistically significant association with cognitive performance. Given the high prevalence of deficiencies in these nutrients, folate and cobalamin supplementation trials are required to measure any beneficial effect on cognition.

Previous studies suggest that welders frequently display parkinsonian signs, such as bradykinesia and tremor. Demonstrating that these parkinsonian findings are associated with reductions in quality of life (QoL) or health status could have important repercussions for worker safety and performance. Subjects included 394 active workers exposed to welding fumes and evaluated for parkinsonism by movement disorders experts in a worksite-based epidemiology study. Subjects were diagnosed with parkinsonism if the Unified Parkinson Disease Rating Scale motor subsection part 3 (UPDRS3) score was ≥15. All subjects completed a Parkinson's disease (PD) symptom questionnaire and the PDQ39, a widely used QoL and health status measure for PD. Total PDQ39 score and all subscores were greater in welders with parkinsonism than welders without parkinsonism, with the most significant differences observed for mobility, emotional well-being, and activities of daily living (ADL's). The PDQ39 scores for welding exposed workers with parkinsonism were similar to scores seen in a group of early PD patients. Parkinsonism in active, welding exposed workers is associated with reductions in health status and QoL affecting a broad range of categories and within the range seen in early PD.

The phase III RAINBOW trial demonstrated that the addition of ramucirumab to paclitaxel improved overall survival, progression-free survival, and tumor response rate in fluoropyrimidine-platinum previously treated patients with advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma. Here, we present results from quality-of-life (QoL) and performance status (PS) analyses. Patients with Eastern Cooperative Oncology Group PS of 0/1 were randomized to receive ramucirumab (8 mg/kg i.v.) or placebo on days 1 and 15 of a 4-week cycle, with both arms receiving paclitaxel (80 mg/m(2)) on days 1, 8, and 15. Patient-reported outcomes were assessed with the QoL/health status questionnaires EORTC QLQ-C30 and EQ-5D at baseline and 6-week intervals. PS was assessed at baseline and day 1 of every cycle. Time to deterioration (TtD) in each QLQ-C30 scale was defined as randomization to first worsening of ≥10 points (on 100-point scale) and TtD in PS was defined as first worsening to ≥2. Hazard ratios (HRs) for treatment effect were estimated using stratified Cox proportional hazards models. Of the 665 patients randomized, 650 (98%) provided baseline QLQ-C30 and EQ-5D data, and 560 (84%) also provided data from ≥1 postbaseline time point. Baseline scores for both instruments were similar between arms. Of the 15 QLQ-C30 scales, 14 had HR < 1, indicating similar or longer TtD in QoL for ramucirumab + paclitaxel. Treatment with ramucirumab + paclitaxel was also associated with a delay in TtD in PS to ≥2 (HR = 0.798, P = 0.0941). Alternate definitions of PS deterioration yielded similar results: PS ≥ 3 (HR = 0.656, P = 0.0508), deterioration by ≥1 PS level (HR = 0.802, P = 0.0444), and deterioration by ≥2 PS levels (HR = 0.608, P = 0.0063). EQ-5D scores were comparable between treatment arms, stable during treatment, and worsened at discontinuation. In patients with previously treated advanced gastric/GEJ adenocarcinoma, addition of ramucirumab to paclitaxel prolonged overall survival while maintaining patient QoL with delayed symptom worsening and functional status deterioration.

The main objective of this study was to investigate the use and user experience of an Information Communication Technology-supported home exercise program when offered for independent use to pre-frail older adults. Our secondary aim was to explore whether the program improved quality of life and health status compared to a control group. A cohort multiple randomized controlled trail is being performed. Physically pre-frail older adults (65-75 years) living independently at home were included and randomly assigned to a control group or an intervention group. The intervention group received a home exercise program (strength, balance, and flexibility exercises) for a minimal duration of 12 weeks. The control group received usual care. Primary outcomes were: use of the intervention (frequency and duration), adherence to a 3-day exercise protocol and user experience [System Usability Scale (SUS); rating 1-10]. Secondary outcomes were quality of life measured with the SF12 (Physical Component Scale and Mental Component Scale) and health status (EQ-5D), assessed before the study starts and after 12 weeks of exercising. Thirty-seven independently living older adults participated in the study. Sixteen participants were allocated to the intervention group and 21 to the control group. The average score on the SUS was 84.2 (±13.3), almost reaching an excellent score. Participants rated the intervention with an 8.5. Eighty percent of the participants finished the 12 week exercise protocol. The adherence to the 3-day exercise protocol was 68%. Participants in the intervention group trained on average 2.2 times (±1.3) each week. The mean duration of login for each exercise session was 24 min. The Mental Component Scale of the SF12 was significantly higher in the intervention group compared to the control group. A trend was seen in the change over time in the health status between groups. This study provides evidence that a home-based exercise program is easy to use and has potential in improving quality of life and health status of pre-frail older adults who live at home. However, further refinement of the program is required to improve adherence and maximize the benefits and potential of exercising in the home environment. Unique Identifier: NTR5304.

The study examined the contribution of parents' occupational status and expectations regarding persons with hearing loss to career-related support they provide their deaf and hard of hearing (dhh) adolescent children. Thirty-eight parents completed the Evaluation of Occupational Competence Scale (Weisel & Cinamon, 2005), the Evaluation of Family Competence Scale (Caprara, Regalia, Scabini, Barbaranelli, & Bandura, 2004), the Career-Related Parent Support Scale (Turner, Alliman-Brissett, Lapan, Udipi, & Ergun, 2003), and a background questionnaire. Parents' occupational expectations were positively correlated with their family expectations regarding deaf persons. Parents' occupational status contributed to expectations of success for deaf persons in prestigious occupations with high communication demands. Different types of expectations contributed to career-related parental support. Implications for theory and practice are discussed.

The Bipolar Depression Rating Scale (BDRS) arguably better captures symptoms in bipolar depression especially depressive mixed states than traditional unipolar depression rating scales. The psychometric properties of the Spanish adapted version, BDRS-S, are reported. The BDRS was translated into Spanish by two independent psychiatrists fluent in English and Spanish. After its back-translation into English, the BDRS-S was administered to 69 DSMI-IV bipolar I and II patients who were recruited from two Spanish psychiatric hospitals. The Hamilton Depression Rating Scale (HDRS), the Montgomery-Asberg Depression Rating Scale (MADRS) and the Young Mania Rating Scale (YMRS) were concurrently administered. 42 patients were reviewed via video by four psychiatrists blind to the psychopathological status of those patients. In order to assess the BDRS-S intra-rater or test-retest validity, 22 subjects were assessed by the same investigator performing two evaluations within five days. The BDRS-S had a good internal consistency (Cronbach׳s α=0.870). We observed strong correlations between the BDRS-S and the HDRS (r=0.874) and MADRS (r=0.854) and also between the mixed symptom cluster score of the BDRS-S and the YMRS (r=0.803). Exploratory factor analysis revealed a three factor solution: psychological depressive symptoms cluster, somatic depressive symptoms cluster and mixed symptoms cluster. A relatively small sample size for a 20-item scale. The BDRS-S provides solid psychometric performance and in particular captures depressive or mixed symptoms in Spanish bipolar patients.

The purpose of this study was to present a new periapical and endodontic status scale (PESS) that is based on the complex periapical index (COPI), which was designed for the identification and classification of periapical bone lesions in cases of apical periodontitis, and the endodontically treated tooth index, which was designed for endodontic treatment quality evaluation by means of cone-beam computed tomographic (CBCT) analysis. Periapical and endodontic status parameters were selected from the already known indexes and scientific literature for radiologic evaluation. Radiographic images (CBCT imaging, digital orthopantomography [DOR], and digital periapical radiography) from 55 patients were analyzed. All parameters were evaluated on CBCT, DOR, and digital periapical radiographic images by 2 external observers. The statistical analysis was performed with software SPSS version 19.0 (SPSS Inc, Chicago, IL). Chi-square tests were used to compare frequencies of qualitative variables. The level of significance was set at P ≤ .05. Overall intraobserver and interobserver agreements were very good and good, respectively. CBCT analysis found more lesions and lesions of bigger dimension (P < .001). CBCT imaging was also superior in locating lesions in the apical part on the side compared with DOR and in the diagnosis of cortical bone destruction compared with both methods (P < .001). Through CBCT analysis, more root canals and more canals associated with lesions were found. The most informative and reproducible periapical and endodontic status parameters were selected, and a new PESS was proposed. The classification proposed in the present study seems to be reproducible and objective and adds helpful information with respect to the existing indexes. Future studies need to be conducted to validate PESS. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

Parent-adolescent interaction and risk of adolescent internet addiction: a population-based study in Shanghai

PubMed Central

2014-01-01

Background Family-based intervention is essential for adolescents with behavioral problems. However, limited data are available on the relationship between family-based factors and adolescent internet addiction (AIA). We aimed to examine this relationship using a representative sample of Shanghai adolescents. Methods In October 2007, a total of 5122 adolescents were investigated from 16 high schools via stratified-random sampling in Shanghai. Self-reported and anonymous questionnaires were used to assess parent-adolescent interaction and family environments. AIA was assessed by DRM-52 Scale, developed from Young’s Internet-addiction Scale, using seven subscales to evaluate psychological symptoms of AIA. Results Adjusting for adolescents’ ages, genders, socio-economic status, school performances and levels of the consumption expenditure, strong parental disapproval of internet-use was associated with AIA (vs. parental approval, OR = 2.20, 95% CI: 1.24-3.91). Worse mother-adolescent relationships were more significantly associated with AIA (OR = 3.79, 95% CI: 2.22-6.48) than worse father-adolescent relationships (OR = 1.76, 95% CI: 1.10-2.80). Marital status of “married-but-separated” and family structure of “left-behind adolescents” were associated with symptoms of some subscales. When having high monthly allowance, resident students tended to develop AIA but commuter students did not. Family social-economic status was not associated with the development of AIA. Conclusions The quality of parent-adolescent relationship/communication was closely associated with the development of AIA, and maternal factors were more significantly associated with development of AIA than paternal factors. Family social-economic status moderated adolescent internet-use levels but not the development of AIA. PMID:24731648

Background and aims To determine the relationship between the risk of exercise addiction (REA) and health status in amateur endurance cyclists. Methods In 859 (751 men and 108 women) cyclists and 718 inactive subjects (307 men and 411 women), we examined the REA (Exercise Addiction Inventory), training status (volume, frequency, experience, and performance), socioeconomic status, quality of life (QoL) (SF-12), quality of sleep (Pittsburgh Sleep Quality Index), anxiety and depression (Hospital Anxiety and Depression Scale), and cardiometabolic risk: body mass index, physical activity (International Physical Activity Questionnaire), physical condition (International Fitness Scale), adherence to the Mediterranean diet (Mediterranean Diet Adherence Screener), alcohol and tobacco consumption. Results In total, 17% of the cyclists showed evidence of REA and 83% showed low REA. REA occurred independent of age, sex, training, and socioeconomic status (all ps > .05). Regardless of REA, the cyclists displayed a better physical QoL and a lower cardiometabolic risk than the inactive subjects (all ps < .05). The cyclists with REA displayed worse values of mental QoL, quality of sleep, and anxiety than cyclists with low REA (all ps < .05). The REA group had better values of mental QoL and anxiety and similar values of quality of sleep than the inactive subjects. The differences in mental QoL between the REA and low REA groups were significantly greater in women (p = .013). There was no Addiction × Sex interaction in the other analyzed variables. Conclusion Our results suggest that an increased prevalence of REA limits the benefits that amateur endurance cycling has on mental health and quality of sleep. PMID:28358644

Background and aims To determine the relationship between the risk of exercise addiction (REA) and health status in amateur endurance cyclists. Methods In 859 (751 men and 108 women) cyclists and 718 inactive subjects (307 men and 411 women), we examined the REA (Exercise Addiction Inventory), training status (volume, frequency, experience, and performance), socioeconomic status, quality of life (QoL) (SF-12), quality of sleep (Pittsburgh Sleep Quality Index), anxiety and depression (Hospital Anxiety and Depression Scale), and cardiometabolic risk: body mass index, physical activity (International Physical Activity Questionnaire), physical condition (International Fitness Scale), adherence to the Mediterranean diet (Mediterranean Diet Adherence Screener), alcohol and tobacco consumption. Results In total, 17% of the cyclists showed evidence of REA and 83% showed low REA. REA occurred independent of age, sex, training, and socioeconomic status (all ps > .05). Regardless of REA, the cyclists displayed a better physical QoL and a lower cardiometabolic risk than the inactive subjects (all ps < .05). The cyclists with REA displayed worse values of mental QoL, quality of sleep, and anxiety than cyclists with low REA (all ps < .05). The REA group had better values of mental QoL and anxiety and similar values of quality of sleep than the inactive subjects. The differences in mental QoL between the REA and low REA groups were significantly greater in women (p = .013). There was no Addiction × Sex interaction in the other analyzed variables.

The aim of this study was to examine the influence of hormonal status, anthropometric profile, sexual maturity level, and physical performance on the technical abilities of 40 young male soccer players during small-sided games (SSGs). Anthropometric profiling, saliva sampling, sexual maturity assessment (Tanner scale), and physical performance tests (Yo-Yo and vertical jumps) were conducted two weeks prior to the SSGs. Salivary testosterone was determined by the enzyme-linked immunosorbent assay method. Technical performance was determined by the frequency of actions during SSGs. Principal component analyses identified four technical actions of importance: total number of passes, effectiveness, goal attempts, and total tackles. A multivariate canonical correlation analysis was then employed to verify the prediction of a multiple dependent variables set (composed of four technical actions) from an independent set of variables, composed of testosterone concentration, stage of pubic hair and genitalia development, vertical jumps and Yo-Yo performance. A moderate-to-large relationship between the technical performance set and the independent set was observed. The canonical correlation was 0.75 with a canonical R 2 of 0.45. The highest structure coefficient in the technical performance set was observed for tackles (0.77), while testosterone presented the highest structure coefficient (0.75) for the variables of the independent set. The current data suggest that the selected independent set of variables might be useful in predicting SSG performance in young soccer players. Coaches should be aware that physical development plays a key role in technical performance to avoid decision-making mistakes during the selection of young players.

Scaling functional status within the interRAI suite of assessment instruments

PubMed Central

2013-01-01

Background As one ages, physical, cognitive, and clinical problems accumulate and the pattern of loss follows a distinct progression. The first areas requiring outside support are the Instrumental Activities of Daily Living and over time there is a need for support in performing the Activities of Daily Living. Two new functional hierarchies are presented, an IADL hierarchical capacity scale and a combination scale integrating both IADL and ADL hierarchies. Methods A secondary analyses of data from a cross-national sample of community residing persons was conducted using 762,023 interRAI assessments. The development of the new IADL Hierarchy and a new IADL-ADL combined scale proceeded through a series of interrelated steps first examining individual IADL and ADL item scores among persons receiving home care and those living independently without services. A factor analysis demonstrated the overall continuity across the IADL-ADL continuum. Evidence of the validity of the scales was explored with associative analyses of factors such as a cross-country distributional analysis for persons in home care programs, a count of functional problems across the categories of the hierarchy, an assessment of the hours of informal and formal care received each week by persons in the different categories of the hierarchy, and finally, evaluation of the relationship between cognitive status and the hierarchical IADL-ADL assignments. Results Using items from interRAI’s suite of assessment instruments, two new functional scales were developed, the interRAI IADL Hierarchy Scale and the interRAI IADL-ADL Functional Hierarchy Scale. The IADL Hierarchy Scale consisted of 5 items, meal preparation, housework, shopping, finances and medications. The interRAI IADL-ADL Functional Hierarchy Scale was created through an amalgamation of the ADL Hierarchy (developed previously) and IADL Hierarchy Scales. These scales cover the spectrum of IADL and ADL challenges faced by persons in the community. Conclusions An integrated IADL and ADL functional assessment tool is valuable. The loss in these areas follows a general hierarchical pattern and with the interRAI IADL-ADL Functional Hierarchy Scale, this progression can be reliably and validly assessed. Used across settings within the health continuum, it allows for monitoring of individuals from relative independence through episodes of care. PMID:24261417

Day-to-Day Variability of Postural Sway and Its Association With Cognitive Function in Older Adults: A Pilot Study

2018-01-01

Introduction: Increased variability in motor function has been observed during the initial stages of cognitive decline. However, the natural variability of postural control, as well as its association with cognitive status and decline, remains unknown. The objective of this pilot study was to characterize the day-to-day variability in postural sway in non-demented older adults. We hypothesized that older adults with a lower cognitive status would have higher day-to-day variability in postural sway. Materials and Methods: A Nintendo Wii balance board (WBB) was used to quantify postural sway in the home twice daily for 30 days in 20 non-demented, community-dwelling older adults: once under a single-task condition and once under a dual-task condition (using a daily word search task administered via a Nook tablet). Mean sway distance, velocity, area, centroidal frequency and frequency dispersion were derived from the center of pressure data acquired from the WBB. Results: Linear relationships were observed between the day-to-day variability in postural sway and cognitive status (indexed by cognitive global z-scores). More variability in time-domain postural sway (sway distance and area) and less variability in frequency-domain postural sway (centroidal sway frequency) were associated with a lower cognitive status under both the single- and dual-task conditions. Additionally, lower cognitive performance rates on the daily word search task were related to a lower cognitive status. Discussion: This small pilot study conducted on a short time scale motivates large-scale implementations over more extended time periods. Tracking longitudinal changes in postural sway may further our understanding of early-stage postural decline and its association with cognitive decline and, in turn, may aid in the early detection of dementia during preclinical stages when the utility of disease-modifying therapies would be greatest.

The purpose of this study was to determine quality of life, leisure time satisfaction, activity performance, and community participation and analyze the relationship between these determinants and community participation in both physically disabled individuals working in industrial environments and nonworking individuals who are physically disabled. Sociodemographic data was registered into a sociodemographic form. World Health Organization Disability Assessment Schedule 2.0 was used to assess community participation. Activity performance was evaluated with Canadian Occupational Performance Measure. Leisure Satisfaction Scale was used to determine leisure time satisfaction. Short Form-36 was used for evaluating quality of life. When the participants were compared in terms of working status, a significant difference according to their WHO-DAS-II total scores were found (p < 0.05). When all participants were compared in terms of activity performance, lesisure time satisfaction, quality of life a significant differences according to their WHO-DAS-II total scores were found (p>0.05). This study shows that community participation was affected by working status, disability level, activity performance, leisure time satisfaction and quality of life. In this regard, occupational therapy and physiotherapy approaches were found necessary for developing community participation. We conclude that this study's results can be used as a guide for community participation in disabled people in community based rehabilitation politics.

To test psychometrics of the Short Form 36 Health Survey version 2 (SF-36v2) and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0) in Chinese mainland patients with methadone maintenance treatment (MMT). A total of 1,212 patients were recruited from two MMT clinics in Xi'an, China. Reliability was estimated with Cronbach's α and intra-class correlation (ICC). Convergent and discriminant validity was assessed using multitrait-multimethod correlation matrix. Sensitivity was measured with ANOVA and relative efficiency. Responsiveness was evaluated by pre-post paired-samples t-test and standardized response mean based on the patients' health status changes following 6-month period. Cronbach's α of the SF-36v2 physical and mental summary components were 0.80 and 0.86 (eight scales range 0.73-0.92) and the QOL-DAv2.0 was 0.96 (four scales range: 0.80-0.93). ICC of the SF-36v2 two components were 0.86 and 0.85 (eight scales range: 0.72-0.87) and the QOL-DAv2.0 was 0.94 (four scales range: 0.88-0.92). Convergent validity was lower between the two instruments (γ <0.70) while discriminant validity was acceptable within each instrument. Sensitivity was satisfied in self-evaluated health status (both instruments) and average daily methadone dose (SF-36v2 physical functioning and vitality scales; QOL-DAv2.0 except psychology scale). Responsiveness was acceptable in the improved health status change (SF-36v2 except vitality scale; QOL-DAv2.0 except psychology and symptoms scales) and deteriorated health status change (SF-36v2 except vitality, social functioning and mental health scales; QOL-DAv2.0 except society scale). The SF-36v2 and the QOL-DAv2.0 are valid tools and can be used independently or complementary according to different emphases of health-related quality of life evaluation in patients with MMT.

Continuously monitoring the operation of each individual fan can significantly improve the measurement quality of aerial pollutant emissions from animal buildings that have a large number of fans. To monitor the fan operation by detecting the fan vibration is a relatively new technique. A low-cost electronic vibration sensor was developed and commercialized. However, its large scale application has not yet been evaluated. This paper presents long-term performance results of this vibration sensor at two large commercial layer houses. Vibration sensors were installed on 164 fans of 130 cm diameter to continuously monitor the fan on/off status for two years. The performance of the vibration sensors was compared with fan rotational speed (FRS) sensors. The vibration sensors exhibited quick response and high sensitivity to fan operations and therefore satisfied the general requirements of air quality research. The study proved that detecting fan vibration was an effective method to monitor the on/off status of a large number of single-speed fans. The vibration sensor itself was $2 more expensive than a magnetic proximity FRS sensor but the overall cost including installation and data acquisition hardware was $77 less expensive than the FRS sensor. A total of nine vibration sensors failed during the study and the failure rate was related to the batches of product. A few sensors also exhibited unsteady sensitivity. As a new product, the quality of the sensor should be improved to make it more reliable and acceptable. PMID:22163544

After preliminary studies aimed at measuring pertinent biochemical parameters, potentially modified in subjects exposed to bad environmental conditions, a dedicated study was performed in Shanghai city to evaluate the effect of Urban pollution upon human skin and to collect feedback from the volunteers under study. This study was performed during summer 2008 in two different districts of Shanghai, on 159 local residents: 79 subjects from Xu Jia Hui (a centre Shanghainese area), more exposed to pollution, and 80 subjects from Chong Ming, an agricultural region closely located north of Shanghai (<100 kms) and less exposed to pollution, according to official data. Biochemical parameters were measured on skin, and feedback from volunteers was collected through a graduated 'Likert scale' questionnaire under a point scale (strongly agree, agree, disagree, strongly disagree and none). The study demonstrated significant differences in several biochemical parameters measured in Chong Ming area, as compared to Urban area, with an increased ratio of squalene/lipids, a lower level of lactic acid and a better cohesion of stratum corneum. Both sebum excretion rate and sebum casual levels did not differ between the two districts. The volunteer's feedback evidenced a perceived link between pollution and their skin problems. This study demonstrated a significant impact of the pollution upon the skin status, as illustrated by changes in superficial biochemical parameters and volunteers' perception. © 2015 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Multiple risk factors contribute to cognitive impairment in children with β-thalassemia major. For a more refined understanding of this issue, we attempted to evaluate cognitive function in β-thalassemia major patients and identify the relationship between possible cognitive dysfunction and the following: demography, transfusion and chelation characteristics, iron overload, and disease complications. We studied 100 β-thalassemia major children and 100 healthy controls who matched well in terms of age, sex, and socioeconomic status. All participants underwent psychometric assessment using Wechsler Intelligence Scale for Children-Third Edition, Arabic version. The mean Full-Scale IQ and Performance IQ of patients were significantly lower than those of controls, whereas no significant difference was found for Verbal IQ. No significant relationship existed between IQ and any of the assessed parameters. We concluded that Performance IQ, not Verbal IQ, was significantly affected in β-thalassemia major patients, but there was no clear association between IQ and any of the parameters. © The Author(s) 2014.

The present study aimed to determine the predictors of quality of life (QOL) of patients with advanced cancer. A cross-sectional study involving 494 patients with advanced cancer was conducted using the Memorial Symptom Assessment Scale-Short Form, the Karnofsky Performance Status Scale, the World Health Organization Disability Assessment Schedule (Korean version), and the European Organization for Research and Treatment of Cancer Quality of Life Core 30. Regression analyses showed that physical and psychological symptoms significantly predicted the patients' QOL and explained 28.8% of the variance in QOL. Moreover, lack of energy was the patients' most prevalent symptom. The results of the present study will serve as fundamental data upon which the development of an intervention will be based so as to enhance the patients' QOL. Accordingly, an effective management of symptoms and performance maintenance should be considered in the future as key factors in providing support and establishing palliative care systems for patients with advanced cancer.

For half a century aqueous two-phase systems (ATPSs) have been applied for the extraction and purification of biomolecules. In spite of their simplicity, selectivity, and relatively low cost they have not been significantly employed for industrial scale bioprocessing. Recently their ability to be readily scaled and interface easily in single-use, flexible biomanufacturing has led to industrial re-evaluation of ATPSs. The purpose of this review is to perform a SWOT analysis that includes a discussion of: (i) strengths of ATPS partitioning as an effective and simple platform for biomolecule purification; (ii) weaknesses of ATPS partitioning in regard to intrinsic problems and possible solutions; (iii) opportunities related to biotechnological challenges that ATPS partitioning may solve; and (iv) threats related to alternative techniques that may compete with ATPS in performance, economic benefits, scale up and reliability. This approach provides insight into the current status of ATPS as a bioprocessing technique and it can be concluded that most of the perceived weakness towards industrial implementation have now been largely overcome, thus paving the way for opportunities in fermentation feed clarification, integration in multi-stage operations and in single-step purification processes.

The Berg Balance Scale (BBS), the Balance Evaluation Systems Test (BESTest), the Mini-BESTest, and the Brief-BESTest are useful tests to assess balance; however, their clinimetric properties have not been studied well in older adults with type 2 diabetes (T2D). This study compared the validity and relative ability of the BBS, BESTest, Mini-BESTest, and Brief-BESTest to identify fall status in older adults with T2D. This study involved a cross-sectional design. Sixty-six older adults with T2D (75 ± 7.6 years) were included and asked to report the number of falls during the previous 12 months and to complete the Activities-specific Balance Confidence scale. The BBS and the BESTest were administered, and the Mini-BESTest and Brief-BESTest scores were computed based on the BESTest performance. Receiver operating characteristics were used to assess the ability of each balance test to differentiate between participants with and without a history of falls. The 4 balance tests were able to identify fall status (areas under the curve = 0.74-0.76), with similar sensitivity (60%-67%) and specificity (71%-76%). The 4 balance tests were able to differentiate between older adults with T2D with and without a history of falls. As the BBS and the BESTest require longer application time, the Brief-BESTest may be an appropriate choice to use in clinical practice to detect fall risk.

This study examined the mediating role of coparenting in the association between differences/similarities in paternal and maternal socioeconomic status (SES) and paternal involvement in Chinese families. The sample included 244 couples with children aged 3-7 years. Fathers and mothers reported their individual incomes, educational levels, occupations, and coparenting behavior (measured using the Coparenting Scale), and fathers completed the Father Involvement Questionnaire. Structural equation modeling was performed to examine the associations between SES and paternal involvement. Results suggested that SES indicator measures were outcome specific. Occupational differences/similarities were associated with paternal involvement indirectly, via fathers' family integrity practices. Income and educational differences/similarities did not affect paternal involvement. The results suggested that the traditional Chinese view that "men are chiefly responsible for activity in society, while women are responsible for the home" has faded.

We examined whether extending the administration time of letter fluency from one minute per letter trial (standard administration) to two minutes increased the sensitivity of this test to cognitive status in aging. Participants (mean age = 84.6) were assigned to cognitive impairment (n=20) and control (n=40) groups. Pearson correlations and scatter plot analyses showed that associations between the Dementia Rating Scale scores and letter fluency were higher and less variable when performance on the latter was extended to two minutes. ANOVA showed that the cognitive impairment group generated fewer words in the second minute of the letter fluency task compared to the control group. Finally, discriminant function analyses revealed that extending the letter fluency trials to two minutes increased discrimination between the control and cognitive impairment groups. PMID:19449244

Temporal orientation is often disrupted in the context of psychiatric or neurological disease; tests assessing this function are included in most mental status examinations. The present study examined the relationship between scores on the Temporal Orientation Scale (TOS) and performance on a battery of tests that assess memory, language, and cognitive functioning in a sample of patients with Alzheimer's disease (N = 55). Pearson-product moment correlations showed that, in all but two instances, the TOS was significantly correlated with each neuropsychological measure, p values < or = .05. Also, severely disoriented (i.e., TOS score < or = -8) patients were consistently 'impaired' on memory tests but not on tests of language and general cognitive functioning.

Multiple sclerosis is one of the most common neurological disorders. It is a chronic inflammatory demyelinating disease of the CNS, whose etiology is not fully understood. Application of new rehabilitation methods are essential to improve functional status. The material studied consisted of 120 patients of both sexes (82 women and 38 men) aged 21-81 years. The study involved patients with a diagnosis of multiple sclerosis. The aim of the study was to evaluate the effect of laser radiation and other therapies on the functional status of patients with multiple sclerosis. Patients were randomly divided into four treatment groups. The evaluation was performed three times - before the start of rehabilitation, immediately after rehabilitation (21 days of treatment) and subsequent control - 30 days after the patients leave the clinic. The following tests were performed for all patients to assess functional status: Expanded Disability Status Scale (EDSS) of Kurtzke and Barthel Index. Results of all testing procedures show that the treatment methods are improving the functional status of patients with multiple sclerosis, with the significant advantage of the synergistic action of laser and magneto stimulation. The combination of laser and magneto stimulation significantly confirmed beneficial effect on quality of life. The results of these studies present new scientific value and are improved compared to program of rehabilitation of patients with multiple sclerosis by laser radiation which was previously used. This study showed that synergic action of laser radiation and magneto stimulation has a beneficial effect on improving functional status, and thus improves the quality of life of patients with multiple sclerosis. The effects of all methods of rehabilitation are persisted after cessation of treatment applications, with a particular advantage of the synergistic action of laser radiation and magneto stimulation, which indicates the possibility to elicitation in these methods the phenomenon of the biological hysteresis.

Oral health has strong biological, psychological, and social projections, which influence the quality of life. Thus, developing a common vision and a comprehensive approach to address children's social, emotional, and behavioral health needs is an integral part of the child and adolescent's overall health. To assess and compare the behavior and emotional difficulties among 15-year-olds and to correlate it with their dentition status based on gender. Study Settings and Design: A cross-sectional questionnaire study among 15-year-old schoolgoing children in six private schools in Dilsukhnagar, Hyderabad, India. The behavior and emotional difficulties were assessed using self-reported Strengths and Difficulties Questionnaire (SDQ). The dentition status was recorded by the criteria given by the World Health Organization (WHO) in the Basic Oral Health Survey Assessment Form (1997). Independent Student's t-test was used for comparison among the variables. Correlation between scales of SDQ and dentition status was done using Karl Pearson's correlation coefficient method. Girls reported more emotional problems and good prosocial behavior and males had more conduct problems, hyperactivity, peer problems, and total difficulty problems. Total decayed-missing-filled teeth (DMFT) and decayed component were significantly and positively correlated with total difficulty, emotional symptom, and conduct problems scale while missing component was correlated with the hyperactivity scale and filled component with prosocial behavior. DMFT and its components showed an association with all scales of SDQ except for peer problem scale. Thus, the oral health of children was significantly influenced by behavioral and emotional difficulties; so, changes in the mental health status will affect the oral health of children.

One of the most widely disseminated methods of assessing psychological stress is the Perceived Stress Scale (PSS-4). Therefore, in order to identify these factors and their impact on mental health, the present study compares the PSS-4 results among three European countries (Great Britain, France and Spain). This study focuses on PSS-4 results within a Spanish sample to determine: (1) normative data, reliability and validity of PSS-4 in a Spanish sample and (2) how stress perception changes depending on cultural and social factors. Methods: The data were obtained from a website representing a service of a smoking cessation program, the study represented a service that was open to all individuals. The number of participants were 37,451. They reported their age, gender, nationality, marital status, education and employment status, and completed two psychological questionnaires (PPS-4 and the anxiety and depression scales of the Symptom Checklist-90-Revised, SCL 90-R). Results: The PSS-4 scores could differentiate between relevant sociodemographic variables (such as sex, age, nationality, marital status, education, parental status, employment status, and income class). The PSS-4 scores showed a positive correlation with the SCL 90-R anxiety and depression scales. The normed values for interpreting the PSS-4 scores are presented. The PSS-4 showed adequate internal consistency and reliability. Conclusions: The PSS-4 is a useful instrument for assessing stress perception levels in the general population in different countries. Its internal consistency is sufficient for a 4-item scale.

There are limited number of studies investigating extrapulmonary manifestations of bronchiectasis. The purpose of this study was to compare peripheral muscle function, exercise capacity, fatigue, and health status between patients with bronchiectasis and healthy subjects in order to provide documented differences in these characteristics for individuals with and without bronchiectasis. Twenty patients with bronchiectasis (43.5 ± 14.1 years) and 20 healthy subjects (43.0 ± 10.9 years) participated in the study. Pulmonary function, respiratory muscle strength (maximal expiratory pressure - MIP - and maximal expiratory pressure - MEP), and dyspnea perception using the Modified Medical Research Council Dyspnea Scale (MMRC) were determined. A six-minute walk test (6MWT) was performed. Quadriceps muscle, shoulder abductor, and hand grip strength (QMS, SAS, and HGS, respectively) using a hand held dynamometer and peripheral muscle endurance by a squat test were measured. Fatigue perception and health status were determined using the Fatigue Severity Scale (FSS) and the Leicester Cough Questionnaire (LCQ), respectively. Number of squats, 6MWT distance, and LCQ scores as well as lung function testing values and respiratory muscle strength were significantly lower and MMRC and FSS scores were significantly higher in patients with bronchiectasis than those of healthy subjects (p < 0.05). In bronchiectasis patients, QMS was significantly associated with HGS, MIP and MEP (p < 0.05). The 6MWT distance was significantly correlated to LCQ psychological score (p < 0.05). The FSS score was significantly associated with LCQ physical and total and MMRC scores (p < 0.05). The LCQ psychological score was significantly associated with MEP and 6MWT distance (p < 0.05). Peripheral muscle endurance, exercise capacity, fatigue and health status were adversely affected by the presence of bronchiectasis. Fatigue was associated with dyspnea and health status. Respiratory muscle strength was related to peripheral muscle strength and health status, but not to fatigue, peripheral muscle endurance or exercise capacity. These findings may provide insight for outcome measures for pulmonary rehabilitation programs for patients with bronchiectasis.

Recent studies demonstrate the potential of Mobile Health (mHealth) to improve quality of care and efficiency in low- and middle- income countries (LMIC). However, strong evidence of their impact, especially in large scale projects is still missing. The objective of this paper is to provide an overview about the current status of mHealth in LMIC, and to identify Requirements and possible Strategies to strength their health systems. A search in Pubmed was performed, which resulted in 427 articles. Restricting the search to review papers published during the last 5 years, 72 publications were identified and characterized, and the more relevant articles analyzing mHealth use, impact and/or adoption in LMIC from a more generic perspective were analyzed in detail. Finally, based on the literature, and complemented with the authors own reflections and experience, mHealth challenges and strategies were identified and presented according to the WHO Health Systems Framework which identifies six main lines of action to improve the performance of health systems: service delivery, health workforce, health information systems, essential medical products and technologies, health financing and governance.

There is little information regarding motor development of children born at term with low birth weight (LBW), a group that constitutes a large proportion of children in South Asia. We used data from infancy and at school age from a LBW cohort to investigate children's motor performance using causal inference. Cross-sectional follow-up study. Delhi, India. We recruited 912 children aged 5 years who had participated in a trial of vitamin D for term LBW infants in the first 6 months of life. We focused on gross motor development, using the Ages and Stages Questionnaire (ASQ) gross motor scale and several measures of motor performance. We examined the effects on these of current anthropometry, vitamin D status and bone health, controlling for age, sex, season of interview, socioeconomic variables, early growth, recent morbidity, sun exposure and animal food intake. In adjusted analyses, stunted children (height-for-age Z (HAZ) <-2) took longer to run 20 m (0.52 s, 95% CI 0.35 to 0.70; p<0.001) and had greater odds of a failing score on the ASQ (OR 3.00, 95% CI 1.41 to 6.38, p=0.004). Greater arm muscle area was associated with faster run time, and the ability to perform more stands and squats in 15 s. Poorer vitamin D status was associated with the ability to perform more stands and squats. Lower tibia ultrasound Z score was associated with greater hand grip strength. Early growth and current body mass index had no associations with motor outcomes. Current HAZ and arm muscle area showed the strongest associations with gross motor outcomes, likely due to a combination of simple physics and factors associated with stunting. The counterintuitive inverse associations of tibia health and vitamin D status with outcomes may require further research. Published by the BMJ Publishing Group Limited.

The behaviors and beliefs of recreational runners with regard to hydration maintenance are not well elucidated. To examine which beverages runners choose to drink and why, negative performance and health experiences related to dehydration, and methods used to assess hydration status. Cross-sectional study. Marathon registration site. Men (n = 146) and women (n = 130) (age = 38.3 ± 11.3 years) registered for the 2010 Little Rock Half-Marathon or Full Marathon. A 23-item questionnaire was administered to runners when they picked up their race timing chips. Runners were separated into tertiles (Low, Mod, High) based on z scores derived from training volume, expected performance, and running experience. We used a 100-mm visual analog scale with anchors of 0 (never) and 100 (always). Total sample responses and comparisons between tertile groups for questionnaire items are presented. The High group (58±31) reported greater consumption of sport beverages in exercise environments than the Low (42 ± 35 mm) and Mod (39 ± 32 mm) groups (P < .05) and perceived sport beverages to be superior to water in meeting hydration needs (P < .05) and improving performance during runs greater than 1 hour (P < .05). Seventy percent of runners experienced 1 or more incidents in which they believed dehydration resulted in a major performance decrement, and 45% perceived dehydration to have resulted in adverse health effects. Twenty percent of runners reported monitoring their hydration status. Urine color was the method most often reported (7%), whereas only 2% reported measuring changes in body weight. Greater attention should be paid to informing runners of valid techniques to monitor hydration status and developing an appropriate individualized hydration strategy.

To describe the derivation of recent status scores (RSSs) for version 6 of the Addiction Severity Index (ASI-6). 118 ASI-6 recent status items were subjected to nonparametric item response theory (NIRT) analyses followed by confirmatory factor analysis (CFA). Generalizability and concurrent validity of the derived scores were determined. A total of 607 recent admissions to variety of substance abuse treatment programs constituted the derivation sample; a subset (n = 252) comprised the validity sample. The ASI-6 interview and a validity battery of primarily self-report questionnaires that included at least one measure corresponding to each of the seven ASI domains were administered. Nine summary scales describing recent status that achieved or approached both high scalability and reliability were derived; one scale for each of six areas (medical, employment/finances, alcohol, drug, legal, psychiatric) and three scales for the family/social area. Intercorrelations among the RSSs also supported the multi-dimensionality of the ASI-6. Concurrent validity analyses yielded strong evidence supporting the validity of six of the RSSs (medical, alcohol, drug, employment, family/social problems, psychiatric). Evidence was weaker for the legal, family/social support and child problems RSSs. Generalizability analyses of the scales to males versus females and whites versus blacks supported the comparability of the findings, with slight exceptions. The psychometric analyses to derive Addiction Severity Index version 6 recent status scores support the multi-dimensionality of the Addiction Severity Index version 6 (i.e. the relative independence of different life functioning areas), consistent with research on earlier editions of the instrument. In general, the Addiction Severity Index version 6 scales demonstrate acceptable scalability, reliability and concurrent validity. While questions remain about the generalizability of some scales to population subgroups, the overall findings coupled with updated and more extensive content in the Addiction Severity Index version 6 support its use in clinical practice and research. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

Hierarchy stability moderates the effect of status on stress and performance in humans

High social status reduces stress responses in numerous species, but the stress-buffering effect of status may dissipate or even reverse during times of hierarchical instability. In an experimental test of this hypothesis, 118 participants (57.3% female) were randomly assigned to a high- or low-status position in a stable or unstable hierarchy and were then exposed to a social-evaluative stressor (a mock job interview). High status in a stable hierarchy buffered stress responses and improved interview performance, but high status in an unstable hierarchy boosted stress responses and did not lead to better performance. This general pattern of effects was observed across endocrine (cortisol and testosterone), psychological (feeling in control), and behavioral (competence, dominance, and warmth) responses to the stressor. The joint influence of status and hierarchy stability on interview performance was explained by feelings of control and testosterone reactivity. Greater feelings of control predicted enhanced interview performance, whereas increased testosterone reactivity predicted worse performance. These results provide direct causal evidence that high status confers adaptive benefits for stress reduction and performance only when the social hierarchy is stable. When the hierarchy is unstable, high status actually exacerbates stress responses. PMID:27994160

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

Cross-cultural Study of Understanding of Scale and Measurement: Does the everyday use of US customary units disadvantage US students?

2013-06-01

Following a sociocultural perspective, this study investigates how students who have grown up using the SI (Système International d'Unités) (metric) or US customary (USC) systems of units for everyday use differ in their knowledge of scale and measurement. Student groups were similar in terms of socioeconomic status, curriculum, native language transparency of number word structure, type of school, and makeup by gender and grade level, while varying by native system of measurement. Their performance on several tasks was compared using binary logistic regression, ordinal logistic regression, and analysis of variance, with gender and grade level as covariates. Participants included 17 USC-native and 89 SI-native students in a school in Mexico, and 31 USC-native students in a school in the Midwestern USA. SI-native students performed at a significantly higher level estimating the length of a metre and a conceptual task (coordinating relative size and absolute size). No statistically significant differences were found on tasks involving factual knowledge about objects or units, scale construction, or estimation of other units. USC-native students in the US school performed at a higher level on smallest known object. These findings suggest that the more transparent SI system better supports conceptual thinking about scale and measurement than the idiosyncratic USC system. Greater emphasis on the SI system and more complete adoption of the SI system for everyday life may improve understanding among US students. Advancing sociocultural theory, systems of units were found to mediate learner's understanding of scale and measurement, much as number words mediate counting and problem solving.

Homework can have beneficial effects for students; however, it presents challenges, particularly for students with attention problems. Although effective homework interventions exist, intervention development and evaluation has been hampered by the lack of psychometrically sound measures. The primary purpose of this study was to evaluate the construct validity of the Homework Performance Questionnaire (HPQ), Parent and Teacher Versions, in a sample of children with ADHD. A secondary purpose was to examine variations in homework performance as a function of individual characteristics, such as academic achievement, quality of the family-school relationship, and child's diagnostic status. The sample included 91 children (34% female) with ADHD in Grades 2 to 6. Measures included parent and teacher ratings of homework performance and the quality of the parent-teacher relationship as well as direct assessment of child academic achievement and homework performance (i.e., samples of completed assignments). Correlational analyses were used to examine construct validity, and ANOVAs were used to evaluate group differences. Each factor of the HPQ had a significant relationship with other measures of relevant constructs. There were no significant differences in homework performance between groups for ADHD subtype, medication status, or comorbidity, with the exception of learning disability. Children with ADHD and learning disabilities had significantly lower teacher ratings of academic competence. Results of the present study suggest that HPQ scores may be used to make valid inferences about the homework performance of children with attention problems. These rating scales may be helpful in progress monitoring and evaluating intervention effectiveness.

The users' satisfaction is a method for evaluating the efficacy of healthcare system. We aimed to evaluate the association between the users' socioeconomic status (SES) and satisfaction with the healthcare system in Shiraz, Iran. This cross-sectional study was conducted from December, 2013 to March, 2014, in Shiraz, Iran. 3400 households were recruited by multi-stage cluster random sampling. Information about demographic, insurance status, and users' satisfaction was derived from face-to-face interviews. Satisfaction with healthcare system was assessed by using 5-point Likert scale statements, which ranged from "very dissatisfied" to "very satisfied". All statistical analyses were performed using SPSS-21. Overall, 1.6% (55) of the respondents were very satisfied, while 6% (203) were very dissatisfied with healthcare system. Participants were classified into high SES (26.3%), middle SES (47.9%) and low SES (25.8%). It was discovered that the better the SES, the more frequent were the respondents dissatisfied with healthcare system (P<0.001). Also, dissatisfied respondents were significantly older (P=0.036). Moreover, women were more dissatisfied with healthcare system (P=0.005). Also, dissatisfied respondents had significantly a higher level of education than satisfied ones (P<0.001). Furthermore, logistic regression revealed that age (P=0.04), marital status (P=0.01), insurance status (P<0.001), SES (P<0.001), and having supplemental insurance (P=0.02) were determinant factors of satisfaction with healthcare system. This study demonstrated that users' sex, age, educational level, and SES were related to dissatisfaction with healthcare system. Meanwhile, clients' age, SES, insurance status and marital status were recognized as determinant factors.

fall is common in old people and has multiple consequences, physical but also psychological, with a fear of falling which results in reduction in the activities of everyday life, loss of autonomy and entry in dependence. The aim of the study was to evluate the benefit of taking into account the fear of falling in the care of old people who had experienced falls. old people who experienced falls and with a good cognitive status were followed in a day hospital during one year. Evaluation including a specific assessment of the responsibility of the psychological factor, the photolangage, was performed before and after multi-field rehabilitation. We used the rating scales ADL, IADL, SF-36, SAFE, and verbal and analogical scales of the fear of falling. fifteen patients were included (mean age 85 years +/- 5,7). The majority were women living alone, with a good nutritional status, a moderated renal insufficiency, and a comorbidity involving polymedication. Scores on the ADL and IADL scales showed a consolidation of the patients' autonomy, with a slight but significant improvement of the IADL scores (p < 0,05). All scales assessing the fear of falling (visual analogical, verbal scales, SAFE) showed a statistically significant improvement (p<0,001). SF-36 scale, exploring the quality of life perceived by the patients, showed a great deterioration immediately after falling, and a statistically significant improvement on seven of the eight subscales after rehabilitation. The global physical score (GCV) was improved in a nonsignificant way, whereas the global psychic score (MCS) progressed in a statistically significant way (p < 0,001). this pilot study shows that multi-field rehabilitation and adapted assumption of responsibility of fear of falling brings a benefit in term of quality of life and preservation of autonomy in old people living in the community who had experienced falls.

Maternal iodine nutrition and thyroid status may influence neurocognitive development in offspring. This study investigated the effects on the intelligence quotient (IQ) of children born to mothers with different levels of iodine supplementation, with or without the administration of levothyroxine (LT4), prior to and during pregnancy. This pilot, prospective, observational study included four study groups, each comprising 15 mother-child pairs, identified on the basis of maternal histories of iodized salt consumption and LT4 treatment prior to and during pregnancy. The groups were labeled as follows: iodine (I), no iodine (no-I), iodine + LT4 (I + T4), and no iodine + LT4 (no-I + T4). IQ tests were administered to children at 6-12 years of age with the Wechsler Intelligence Scale for Children-3rd Edition (WISC-III), with full-scale IQ (FSIQ), verbal IQ (VIQ), and performance IQ (PIQ) being evaluated. Children of I and I + T4 mothers had similar verbal, performance, and FSIQs, which were 14, 10, and 13 points higher, respectively, than children born to no-I and no-I + T4 mothers. A positive association was found between VIQ and maternal urinary iodine (β = 1.023 [confidence interval (CI) 1.003-1.043]; p = 0.028), but not with maternal free thyroxine concentrations at any stage of pregnancy. Overall, the prevalence of borderline or defective cognitive function was more than threefold higher in the children of mothers not using iodized salt than of those mothers using it (76.9% vs. 23.1%, odds ratio 7.667 [CI 2.365-24.856], χ2 = 12.65; p = 0.0001). Neuro-intellectual outcomes in children appear to be more dependent on their mothers' nutritional iodine status than on maternal thyroid function. These results support the growing body of evidence that prenatal, mild-to-moderate iodine deficiency adversely affects cognitive development later in life, with a seemingly greater impact on verbal abilities.

Effective conservation of fish species of greatest conservation need (SGCN) requires an understanding of species–habitat relationships and distributional trends. Thus, modeling the distribution of fish species across large spatial scales may be a valuable tool for conservation planning. Our goals were to evaluate the status of 10 fish SGCN in wadeable Iowa streams and to test the effectiveness of Iowa Aquatic Gap Analysis Project (IAGAP) species distribution models. We sampled fish assemblages from 86 wadeable stream segments in the Mississippi River drainage of Iowa during 2009 and 2010 to provide contemporary, independent fish species presence–absence data. The frequencies of occurrence in stream segments where species were historically documented varied from 0.0% for redfin shiner Lythrurus umbratilis to 100.0% for American brook lampreyLampetra appendix, with a mean of 53.0%, suggesting that the status of Iowa fish SGCN is highly variable. Cohen's kappa values and other model performance measures were calculated by comparing field-collected presence–absence data with IAGAP model–predicted presences and absences for 12 fish SGCN. Kappa values varied from 0.00 to 0.50, with a mean of 0.15. The models only predicted the occurrences of banded darterEtheostoma zonale, southern redbelly dace Phoxinus erythrogaster, and longnose daceRhinichthys cataractae more accurately than would be expected by chance. Overall, the accuracy of the twelve models was low, with a mean correct classification rate of 58.3%. Poor model performance probably reflects the difficulties associated with modeling the distribution of rare species and the inability of the large-scale habitat variables used in IAGAP models to explain the variation in fish species occurrences. Our results highlight the importance of quantifying the confidence in species distribution model predictions with an independent data set and the need for long-term monitoring to better understand the distributional trends and habitat associations of fish SGCN.

Quantitative MR imaging parameters help to evaluate disease progression in multiple sclerosis and increase correlation with clinical disability. We therefore hypothesized that T1 values might be a marker for ongoing tissue damage or even remyelination and may help increase clinical correlation. MR imaging was performed in 17 patients with relapsing-remitting MS at baseline and after 12 months of starting immunotherapy with dimethyl fumarate. On baseline images, lesion segmentation was performed for normal-appearing white matter, T2 hyperintense (FLAIR lesions), T1 hypointense (black holes), and contrast-enhancing lesions, and T1 relaxation times were obtained at baseline and after 12 months. Changes in clinical status were assessed by using the Expanded Disability Status Scale and Symbol Digit Modalities Test at both dates (Expanded Disability Status Scale-difference/Symbol Digit Modalities Test-diff). The highest T1 relaxation time at baseline was measured in black holes (1460.2 ± 209.46 ms) followed by FLAIR lesions (1400.38 ± 189.1 ms), pure FLAIR lesions (1327.5 ± 210.04 ms), contrast-enhancing lesions (1205.59 ± 199.95 ms), and normal-appearing white matter (851.34 ± 30.61 ms). After 12 months, T1 values had decreased significantly in black holes (1369.4 ± 267.81 ms), contrast-enhancing lesions (1079.57 ± 183.36 ms) (both P < .001), and normal-appearing white matter (841.98 ± 36.1 ms, P = .006). With the Jonckheere-Terpstra Test, better clinical scores were associated with decreasing T1 relaxation times in black holes ( P < .05). T1 relaxation time is a useful quantitative MR imaging technique, which helps detect changes in MS lesions with time. We assume that these changes are associated with the degree of myelination within the lesions themselves and are pronounced in black holes. Additionally, decreasing T1 values in black holes were associated with clinical improvement. © 2017 by American Journal of Neuroradiology.

Fail or flourish? Cognitive appraisal moderates the effect of solo status on performance.

PubMed

White, Judith B

2008-09-01

When everyone in a group shares a common social identity except one individual, the one who is different from the majority has solo status. Solo status increases one's visibility and performance pressure, which may result in stress. Stress has divergent effects on performance, and individuals' response to stressful situations is predicted by their cognitive appraisal (challenge or threat) of the situation. Two experiments test the hypothesis that cognitive appraisal moderates the effect of solo status on performance. Experiment 1 finds that at relatively high appraisal levels (resources exceed demands), solo status improves men's and women's performance; at relatively low appraisal levels, solo status hurts performance. Experiment 2 replicates this effect for solo status based on minimal group assignment. Results suggest that for individuals who feel challenged and not threatened by their work, it may help to be a solo.

Boys' and girls' weight status and math performance from kindergarten entry through fifth grade: a mediated analysis.

This study tests a mediated model of boys' and girls' weight status and math performance with 6,250 children from the Early Childhood Longitudinal Study. Five data points spanning kindergarten entry (mean age=68.46 months) through fifth grade (mean age=134.60 months) were analyzed. Three weight status groups were identified: persistent obesity, later onset obesity, and never obese. Multilevel models tested relations between weight status and math performance, weight status and interpersonal skills and internalizing behaviors, and interpersonal skills and internalizing behaviors and math performance. Interpersonal skills mediated the association between weight status and math performance for girls, and internalizing behaviors mediated the association between weight status and math performance for both sexes, with effects varying by group and time. © 2012 The Authors.

Immune response in a wild bird is predicted by oxidative status, but does not cause oxidative stress.

PubMed

Cram, Dominic L; Blount, Jonathan D; York, Jennifer E; Young, Andrew J

2015-01-01

The immune system provides vital protection against pathogens, but extensive evidence suggests that mounting immune responses can entail survival and fecundity costs. The physiological mechanisms that underpin these costs remain poorly understood, despite their potentially important role in shaping life-histories. Recent studies involving laboratory models highlight the possibility that oxidative stress could mediate these costs, as immune-activation can increase the production of reactive oxygen species leading to oxidative stress. However, this hypothesis has rarely been tested in free-ranging wild populations, where natural oxidative statuses and compensatory strategies may moderate immune responses and their impacts on oxidative status. Furthermore, the possibility that individuals scale their immune responses according to their oxidative status, conceivably to mitigate such costs, remains virtually unexplored. Here, we experimentally investigate the effects of a phytohaemagglutinin (PHA) immune-challenge on oxidative status in wild male and female white-browed sparrow weavers, Plocepasser mahali. We also establish whether baseline oxidative status prior to challenge predicts the scale of the immune responses. Contrary to previous work on captive animals, our findings suggest that PHA-induced immune-activation does not elicit oxidative stress. Compared with controls (n = 25 birds), PHA-injected birds (n = 27 birds) showed no evidence of a differential change in markers of oxidative damage or enzymatic and non-enzymatic antioxidant protection 24 hours after challenge. We did, however, find that the activity of a key antioxidant enzyme (superoxide dismutase, SOD) prior to immune-activation predicted the scale of the resulting swelling: birds with stronger initial SOD activity subsequently produced smaller swellings. Our findings (i) suggest that wild birds can mount immune responses without suffering from systemic oxidative stress, and (ii) lend support to biomedical evidence that baseline oxidative status can impact the scale of immune responses; a possibility not yet recognised in ecological studies of immunity.

Health-related quality of life (HRQOL) is an important outcome in dialysis care. Previous research has related protein-energy nutritional status to generic HRQOL domains, but it is still not clear as to how it relates to HRQOL domains that are unique to hemodialysis patients. Therefore, our aim was to study the relation between protein-energy nutritional status and kidney disease-specific HRQOL domains in hemodialysis patients. This was a cross-sectional study. This study was performed at multiple centers. We evaluated the first 590 hemodialysis patients who had enrolled in the Convective Transport Study. We measured protein-energy nutritional status by using the Subjective Global Assessment, albumin, normalized nitrogen appearance, creatinine, body mass index, and cholesterol. HRQOL was assessed by using the Kidney Disease Quality Of Life-Short Form. In all, 83% of the cohort was found to be well-nourished on the basis of the Subjective Global Assessment. Multiple nutritional parameters were positively related to the physical summary of generic HRQOL and to the following kidney disease-specific HRQOL scales: the effects of the kidney disease on daily life, the burden of the kidney disease, and overall health. This study showed that, even in predominantly well-nourished hemodialysis patients, protein-energy nutritional status was significantly related to kidney disease-specific HRQOL.

Body weight status and telomere length in U.S. middle-aged and older adults.

PubMed

An, Ruopeng; Yan, Hai

Telomere length has been proposed as a biomarker of biological aging. This study examined the relationship between body weight status and telomere length in U.S. middle-aged and older adults. Nationally representative data (N=2749) came from the Health and Retirement Study. Linear regressions were performed to examine the relationship between baseline body weight status reported in 1992 and telomere length measured in 2008 in the overall sample and by sex and racial/ethnic groups, adjusted for individual characteristics. Baseline overweight (25kg/m 2 ≤body mass index [BMI]<30kg/m 2 ) and obesity (BMI≥30kg/m 2 ) status positively predicted telomere length 17 years later. Compared with their normal weight counterparts, telomere length ratio was on average 0.062 (95% confidence interval=0.016, 0.109) and 0.125 (0.048, 0.202) larger among overweight and obese adults, respectively. In comparison to women and racial/ethnic minorities, the estimated positive associations between overweight and obesity status and telomere length were more salient among men and non-Hispanic whites, respectively. The positive association between body weight status and telomere length found in this study was opposite to what existing biological model predicts, and could partially relate to the nonlinear relationship between body weight status and telomere length across age cohorts, and/or the lack of reliability of BMI as an indicator for adiposity in the older population. Large-scale longitudinal studies with baseline telomere length measures are warranted to replicate this study finding and explore the potential heterogeneous relationship between body weight status and telomere length.

A primary brain tumor (PBT) is often a fatal disease of the nervous system and has a serious impact on health-related quality of life (HRQOL). Presence of epilepsy and adverse reactions from tumor and epilepsy treatments may cause additional decline in HRQOL. We aimed to study the impact of epileptic seizures on cognition, mood, and HRQOL in patients with brain tumor-related epilepsy. Patients were grouped on an ordinal scale according to epilepsy burden from none to severe based on the presence of epileptic seizures and seizure frequency: L1, no epilepsy; L2, with epilepsy, seizure-free in the last 6 months with antiepileptic drugs; and L3, with epilepsy, at least one seizure in the last 6 months with AEDs. Health-related quality of life was measured by Functional Assessment of Cancer Therapy-Brain (FACT-Br) and Quality of Life in Epilepsy-31 (QOLIE-31) tools, cognition by the Montreal Cognitive Assessment (MoCA) tool and Frontal Assessment Battery (FAB), mood by the Hospital Anxiety and Depression Scale (HADS), activities of daily living (ADLs) by the Barthel Index (BI), and performance status by the Karnofsky Performance Status (KPS) scale in patients with primary brain tumors at least one month following neurosurgery with or without radiotherapy and chemotherapy. Eighty-one patients with a diagnosis of primary brain tumors were recruited. Sixty-eight percent of patients were diagnosed with primary brain tumor-related epilepsy, 50.61% patients had cognitive impairment, 33% had abnormal scores in the anxiety scale, and 34% had abnormal scores in the depression scale. There were no statistically significant differences in these scores among L1, L2, and L3 groups. There were statistically significant differences in duration of disease and KPS and BI scores between L1 and L3 groups. The L3 group has significantly longer duration of disease and scored low in both the BI and KPS scale when compared to the L1 group. All patients with primary brain tumors scored significantly low in FACT-Br 'physical well-being' (PWB) and 'emotional well-being' (EWB) and high in 'social well-being' (SWB) when compared to healthy controls. When scores of each group were individually compared to healthy controls, the L3 group showed the lowest scores in PWB, EWB, and 'functional well-being'. In SWB, L1 and L2 groups showed statistically significantly high scores when compared to normative data. The QOLIE-31 applied to groups with epilepsy showed statistically significantly lower scores in the L3 group when compared to the L2 group in 'cognitive' and 'social functioning' domains. On multivariate analysis, both poor performance status and frequency of seizures were found to be independent risk factors for poor HRQOL when FACT-Br mean scores were compared. Level of seizures was found to be an independent risk factor for poor HRQOL when QOLIE-31 scores were compared between L2 and L3 groups. Presence of brain tumors could be attributed to cognitive impairment irrespective of the presence of epilepsy in our cohort. High seizure burden is an independent risk factor for poor HRQOL in patients with primary brain tumors. The QOLIE-31 is a more sensitive tool than the FACT-Br because of the presence of a seizure-related questionnaire. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

The Transonic Dynamics Tunnel (TDT) became in operational in 1960, and since that time has achieved the status of the world's premier wind tunnel for testing large in aeroelastically scaled models at transonic speeds. The facility has many features that contribute to its uniqueness for aeroelastic testing. This paper will briefly describe these capabilities and features, and their relevance to aeroelastic testing. Contributions to specific airplane configurations and highlights from the flutter tests performed in the TDT aimed at investigating the aeroelastic characteristics of these configurations are presented.

Methadone maintenance treatment (MMT) patients may achieve up to a 2-week privilege of methadone take-home doses (THD), which is associated with considerable responsibility. MMT patients are characterized as having poor sleep quality and low cognitive states. We studied sleep indices and cognitive status with respect to THD privileges. A sample of 123 MMT patients stratified by THD groups was studied. Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and the cognitive Clock Drawing Test (CDT) were performed. Thirty-one of 123 patients never had any THD and 92 did (25 had the maximum of 2 weeks). The never THD had history of longer duration of opiate usage and a shorter period in MMT. They had the highest rates of poor sleep (80.6%, PSQI > 5), daily sleepiness ("fall asleep while talking") (41.9%), and impaired cognitive status (58.1%, CDT < 3), while those who had 2-week privileges had the lowest (56, 8, and 28%, respectively). Logistic regression characterized THD patients as no-benzodiazepine and no-cocaine, short opiate usage duration, low ADHD scores, and no cognitive impairment (CDT = 3) and its interaction with treatment duration. Privileges that reflect patients' abstinence and rehabilitation were also expanded to be associated with better cognitive states. These finding confirm the THD dispensing performance. Including CDT as part of the decision for dispensing THD may be considered.

Multi-group measurement invariance of the multiple sclerosis walking scale-12?

PubMed

Motl, Robert W; Mullen, Sean; McAuley, Edward

2012-03-01

One primary assumption underlying the interpretation of composite multiple sclerosis walking scale-12 (MSWS-12) scores across levels of disability status is multi-group measurement invariance. This assumption was tested in the present study between samples that differed in self-reported disability status. Participants (n = 867) completed a battery of questionnaires that included the MSWS-12 and patient-determined disease step (PDDS) scale. The multi-group invariance was tested between samples that had PDDS scores of ≤2 (i.e. no mobility limitation; n = 470) and PDDS scores ≥3 (onset of mobility limitation; n = 397) using Mplus 6·0. The omnibus test of equal covariance matrices indicated that the MSWS-12 was not invariant between the two samples that differed in disability status. The source of non-invariance occurred with the initial equivalence test of the factor structure itself. We provide evidence that questions the unambiguous interpretation of scores from the MSWS-12 as a measure of walking impairment between samples of persons with multiple sclerosis who differ in disability status.

To investigate the self-rated health status of the floating population in a district of Guangzhou. Cluster stratified random sampling was applied to survey 219 floating people from a community in Guangzhou, who were assessed with self-rated health status was assessed with Self-Rated Health Measurement Scale. The scores of the floating population were significantly higher than the normal individuals in physical health sub-scales (P<0.01), while the scores of the floating population were significantly lower in psychological and social health sub-scales (P<0.05). The low score items in the subscale of physical health mainly consisted of fatigue and gastrointestinal symptoms, those in the subscale of psychological health mainly in anxiety, depression and obsession, and those in the subscale of social health mainly in participation in social activities and seeking help from others. To improve the health status of the floating population, campaigns of health education need to be launched periodically and psychological counseling should be provided for these individuals. Additionally, interactive activities should be increased in their daily social life.

Influence of family environment on language outcomes in children with myelomeningocele.

Vachha, B; Adams, R

2005-09-01

Previously, our studies demonstrated language differences impacting academic performance among children with myelomeningocele and shunted hydrocephalus (MMSH). This follow-up study considers the environmental facilitators within families (achievement orientation, intellectual-cultural orientation, active recreational orientation, independence) among a cohort of children with MMSH and their relationship to language performance. Fifty-eight monolingual, English-speaking children (36 females; mean age: 10.1 years; age range: 7-16 years) with MMSH were evaluated. Exclusionary criteria were prior shunt infection; seizure or shunt malfunction within the previous 3 months; uncorrected visual or auditory impairments; prior diagnoses of mental retardation or attention deficit disorder. The Comprehensive Assessment of Spoken Language (CASL) and the Wechsler Abbreviated Scale of Intelligence (WASI) were administered individually to all participants. The CASL Measures four subsystems: lexical, syntactic, supralinguistic and pragmatic. Parents completed the Family Environment Scale (FES) questionnaire and provided background demographic information. Spearman correlation analyses and partial correlation analyses were performed. Mean intelligence scores for the MMSH group: full scale IQ 92.2 (SD = 11.9). The CASL revealed statistically significant difficulty for supralinguistic and pragmatic (or social) language tasks. FES scores fell within the average range for the group. Spearman correlation and partial correlation analyses revealed statistically significant positive relationships for the FES 'intellectual-cultural orientation' variable and performance within the four language subsystems. Socio-economic status (SES) characteristics were analyzed and did not discriminate language performance when the intellectual-cultural orientation factor was taken into account. The role of family facilitators on language skills in children with MMSH has not previously been described. The relationship between language performance and the families' value on intellectual/cultural activities seems both statistically and intuitively sound. Focused interest in the integration of family values and practices should assist developmental specialists in supporting families and children within their most natural environment.

Abstract Background Adverse effects of severe maternal iodine deficiency in pregnancy on fetal brain development are well-established, but the effects of milder deficiency are uncertain. Most studies examine iodine status in pregnancy; less is known about iodine nutrition before conception. Objective We examined relations between maternal preconception iodine status and offspring cognitive function, within a prospective mother-offspring cohort. Methods Maternal iodine status was assessed through the use of the ratio of iodine:creatinine concentrations (I/Cr) in spot urine samples [median (IQR) period before conception 3.3 y (2.2–4.7 y)]. Childhood cognitive function was assessed at age 6–7 y. Full-scale IQ was assessed via the Wechsler Abbreviated Scale of Intelligence, and executive function through the use of tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB). Analyses (n = 654 mother-child dyads) were adjusted for potential confounders including maternal intelligence, education, and breastfeeding duration. Results The median (IQR) urinary iodine concentration was 108.4 µg/L (62.2–167.8 µg/L) and the I/Cr ratio 114 µg/g (76–164 µg/g). The preconception I/Cr ratio was positively associated with child IQ, before and after adjustment for potential confounding influences [β = 0.13 (95% CI: 0.04, 0.21)/SD, P = 0.003]. 8.9% of women had a preconception urinary I/Cr ratio <50 µg/g; compared with those with an I/Cr ratio ≥150 µg/g, the IQ of their offspring was 0.49 (95% CI: 0.79, 0.18) SD lower. There were no associations with the executive function outcomes assessed via CANTAB, before or after adjustment for confounders. Conclusion The positive association between iodine status before conception and child IQ provides some support for demonstrated links between low maternal iodine status in pregnancy and poorer cognitive function reported in other studies. However, given the negative effects on school performance previously observed in children born to iodine-deficient mothers, the lack of associations with measures of executive function in the present study was unexpected. Further data are needed to establish the public health importance of low preconception iodine status. PMID:29767745

The increase in the older adult and oldest old population in Brazil is growing. This phenomenon may be accompanied by an increase in musculoskeletal symptoms such as low back pain. This condition is usually associated with disability. To verify the association between pain intensity and disability in older adults with acute low back pain and assess whether these variables differ depending on the age group and marital status. This is a cross-sectional study conducted with 532 older adults with acute low back pain episodes. Pain intensity was assessed through the Numeric Pain Scale and disability through the Late Life Function and Disability Instrument, which shows two dimensions: "frequency" and "limitation" in performing activities. The association between pain and disability was analyzed. For the interaction effect between age groups and marital status, we found that the oldest old living with a partner performed activities of the personal domain less often compared to the oldest old living alone. The oldest old group living with a partner had a lower frequency of performing activities, but did not report feeling limited. The association of pain with disability was minimal (rho<0.20) and thus considered irrelevant. Disability in older adults with acute low back pain was influenced by the interaction between age groups and marital status and is not associated with pain intensity.

Rhodiola Rosea, is an adaptogen plant which has been reported to promote fatty acids utilisation, to ameliorate antioxidant function, and to improve body resistance to physical strenuous efforts. The purpose of the present study was to investigate the effects on physical performance as well as on the redox status of a chronic Rhodiola Rosea supplementation in a group of competitive athletes during endurance exercise. Following a chronic supplementation with Rhodiola Rosea for 4 weeks, 14 trained male athletes underwent a cardio-pulmonary exhaustion test and blood samples to evaluate their antioxidant status and other biochemical parameters. These data were compared with those coming from the same athletes after an intake of placebo. The evaluation of physical performance parameters showed that HR Max, Borg Scale level, VO(2) max and duration of the test were essentially unaffected by Rhodiola Rosea assumption. On the contrary, Rhodiola Rosea intake reduced, in a statistically significative manner, plasma free fatty acids levels. No effect on blood glucose was found. Blood antioxidant status and inflammatory parameters resulted unaffected by Rhodiola Rosea supplementation. Blood lactate and plasma creatine kinase levels were found significantly lower (P<0.05) in Rhodiola Rosea treated subjects when compared to the placebo treated group. Chronic Rhodiola Rosea supplementation is able to reduce both lactate levels and parameters of skeletal muscle damage after an exhaustive exercise session. Moreover this supplementation seems to ameliorate fatty acid consumption. Taken together those observation confirm that Rhodiola Rosea may increase the adaptogen ability to physical exercise.

Background: Despite documented age-related declines in self-reported functional status and measured physical capacity, it is unclear whether these functional indicators follow similar trajectories over time or whether the patterns of change differ by sex. Methods: We used longitudinal data from 687 initially nondisabled adults, aged 70 or older, from the Precipitating Events Project, who were evaluated every 18 months for nearly 14 years. Self-reported disability was assessed with a 12-item disability scale. Physical capacity was measured using grip strength and a modified version of Short Physical Performance Battery. Hierarchical linear models estimated the intra-individual trajectory of each functional indicator and differences in trajectories’ intercept and slope by sex. Results: Self-reported disability, grip strength, and Short Physical Performance Battery score declined over 13.5 years following nonlinear trajectories. Women experienced faster accumulation of self-reported disability, but slower declines in measured physical capacity, compared with men. Trajectory intercepts revealed that women had significantly weaker grip strength and reported higher levels of disability compared with men, with no differences in starting Short Physical Performance Battery scores. These findings were robust to adjustments for differences in sociodemographic characteristics, length-of-survival, health risk factors, and chronic-disease status. Conclusions: Despite the female disadvantage in self-reported disability, older women preserve measured physical capacity better than men over time. Self-reported and measured indicators should be viewed as complementary rather than interchangeable assessments of functional status for both clinical and research purposes, especially for sex-specific comparisons.

Our clinical experience with high - frequency SCS for FBSS in patients with predominant low back pain is presented. After a trial period, 100 % (21 out of 21) of patients with FBSS with predominant low back pain reported a significant improvement in visual analog scale (VAS) pain score and underwent permanent implantation of the high - frequency SCS system. SCS trials lasted 7-14 days (median 9 days). SCS leads were mostly positioned at the T8-10 or T8-12 vertebral levels . We used both single and dual lead placement. VAS, patient satisfaction, patient performance status, opioid consumption and complication rate were assessed for the period of 12 months. The mean VAS score before implantation (8.7) compared to VAS 12 months after implantation (4.0) was significantly lower (CI95[3.9-5.4], p < 0.001). There was a significant improvement in performance status when comparing PS before implantation (3.0) and 12 months after implantation (1.8) (CI95[0.9-1.6], p < 0.001). The mean patient satisfaction scores (PSS) did not differ throughout the whole one year follow-up period. Our group of 21 patients with implanted high - frequency SCS systems reported significant low back pain and leg pain relief within the period of 12 months as well as significant improvement in their performance status. We had a special subgroup of 5 patients with regular change of frequencies between high frequency and conventional frequency (with paresthesia) also with significant leg and low back pain relief (Tab. 2, Fig. 1, Ref. 8).

To describe the prevalence rate of ideational apraxia (IA) affecting self-feeding in people with dementia, confirm the stage of dementia at which IA most commonly occurs, and compare mealtime performance and nutritional status between people with dementia (PWD) with and without IA. A cross-sectional design with between-subject comparison was used. Among the 395 potential participants recruited from dementia special care units at nine long-term care facilities in central and northern Taiwan, 98 met the operational definition of IA and were included in the PWD with IA group. From the remaining pool, 98 participants, matched for age and sex with the PWD with IA group, were randomly allocated to the PWD without IA group. Eating Behavior Scale (EBS) scores, food intake, total eating time, meal assistance, body mass index, Mini-Nutritional Assessment (MNA), and Mini-Mental State Examination scores were collected. The prevalence rate of IA affecting self-feeding in our study population of PWD was 24.8%. PWD with IA had significantly lower EBS scores, had more food intake (p < .001), spent more time being fed by caregivers, needed more verbal and feeding assistance, and had lower MNA scores than PWD without IA. Decline in the self-feeding ability of PWD affected by IA most commonly occurred in the severe stage of dementia. When dementia progresses to the late stage, staff should pay special attention to residents' mealtime performance and nutritional status. For PWD with IA, reassigning staff at mealtimes based on eating ability and providing memory training are recommended. © The Author(s) 2014.

Comprehensive geriatric assessment (CGA) is a complex and interdisciplinary approach to evaluate the health status of elderly patients. The Karnofsky Performance Scale (KPS) and Physical Performance Test (PPT) are less time-consuming tools that measure functional status. This study was designed to assess and compare abridged geriatric assessment (GA), KPS and PPT as predictive tools of mortality in elderly patients with cancer. This prospective interventional study included all individuals aged >70years who were diagnosed with cancer during the study period. Subjects were interviewed directly using a procedure that included a clinical test and a questionnaire composed of the KPS, PPT and abridged GCA. Overall survival (OS) was the primary endpoint. The log rank test was used to compare survival curves, and Cox's regression model (forward procedure) was used for multivariate survival analysis. One hundred patients were included in this study. Abridged GA was the only tool found to predict mortality [median OS for unfit patients (at least two impairments) 467days vs 1030days for fit patients; p=0.04]. Patients defined as fit by mean PPT score (>20) had worse median OS (560 vs 721days); however, this difference was not significant (p=0.488 on log rank). Although median OS did not differ significantly between patients with low (≤80) and high (>80) KPS scores (467 and 795days, respectively; p=0.09), survival curves diverged after nearly 120days of follow-up. Visual and hearing impairments were the only components of abridged GA of prognostic value. Neither KPS nor PPT were shown to predict mortality in elderly patients with cancer whereas abridged GA was predictive. This study suggests a possible role for visual and hearing assessment as screening for patients requiring CGA. Copyright © 2016 Elsevier Ltd. All rights reserved.

Ho, Francis; Lau, Francis; Downing, Michael G; Lesperance, Mary

2008-01-01

Background The Palliative Performance Scale (PPS) was first introduced in1996 as a new tool for measurement of performance status in palliative care. PPS has been used in many countries and has been translated into other languages. Methods This study evaluated the reliability and validity of PPS. A web-based, case scenarios study with a test-retest format was used to determine reliability. Fifty-three participants were recruited and randomly divided into two groups, each evaluating 11 cases at two time points. The validity study was based on the content validation of 15 palliative care experts conducted over telephone interviews, with discussion on five themes: PPS as clinical assessment tool, the usefulness of PPS, PPS scores affecting decision making, the problems in using PPS, and the adequacy of PPS instruction. Results The intraclass correlation coefficients for absolute agreement were 0.959 and 0.964 for Group 1, at Time-1 and Time-2; 0.951 and 0.931 for Group 2, at Time-1 and Time-2 respectively. Results showed that the participants were consistent in their scoring over the two times, with a mean Cohen's kappa of 0.67 for Group 1 and 0.71 for Group 2. In the validity study, all experts agreed that PPS is a valuable clinical assessment tool in palliative care. Many of them have already incorporated PPS as part of their practice standard. Conclusion The results of the reliability study demonstrated that PPS is a reliable tool. The validity study found that most experts did not feel a need to further modify PPS and, only two experts requested that some performance status measures be defined more clearly. Areas of PPS use include prognostication, disease monitoring, care planning, hospital resource allocation, clinical teaching and research. PPS is also a good communication tool between palliative care workers. PMID:18680590

To describe health and wellness characteristics of persons with TBI living in the community, compare to other disability populations and evaluate the associations between health-related constructs. Observational. Outpatient rehabilitation hospital and a Veterans Affairs Medical Centre. Seventy-four community-dwelling adults with moderate-to-severe TBI. None. Health Promoting Lifestyle Profile II (HPLP-II), Self Rated Abilities Health Practices Scale (SRAHP), Barriers to Health Promoting Activities for Disabled Scale (BHPAD), Medical Outcomes Study 12-Item Health Status Survey Short Form (SF-12), Personal Resource Questionnaire-adapted (PRQ-a), Perceived Wellness Survey (PWS), Diener Satisfaction with Life Scale (SWLS) and Participation Assessment with Recombined Tools-Objective (PART-O). Health-promoting behaviours, self-efficacy and barriers to health were comparable to other disability populations. Perceived health status, participation and life satisfaction were decreased. Measures of health promotion and self-efficacy were positively associated with perceived mental health status, life satisfaction and participation. Barriers to healthy activities were negatively associated with health promotion, self-efficacy and perceived mental health status. Health and wellness status was below desired levels for the study cohort, and comparable to other disability populations. Better understanding of associations among health-related constructs is needed. Continued research on conceptually-based health and wellness interventions for persons with TBI is recommended.

Malnutrition is a common phenomenon among the elderly and quite often related to psychosocial problems. The objective of this study was to determine malnutrition risk and its association with appetite, functional and psychosocial status among elderly Malays in an agricultural settlement, i.e. FELDA Sungai Tengi, Selangor. A cross-sectional study was conducted among 160 subjects (men = 36.2%), with a mean age of 65.0 +/- 3.9 years, who were interviewed to obtain information on malnutrition risk and appetite using Mini Nutritional Assessment Short Form and Simplified Nutritional Appetite Questionnaire, respectively. Functional status was determined using Instrumental Activities of Daily Living (IADL), Elderly Mobility Scale (EMS) and handgrip strength. Mini Mental Status Examination (MMSE), Geriatric Depression Scale and De Jong Gierveld Loneliness Scale were used to identify cognitive impairment, depressive symptoms and loneliness status of subjects respectively. A total of 42.5% of subjects were at risk of malnutrition and 61.2% had poor appetite. The mean scores of IADL and EMS were lower in subjects at risk of malnutrition, compared to those who were not at high risk (p < 0.05 for both parameters). Multiple linear regression showed that 19.8% of malnutrition risk was predicted by poor appetite, decreased functional status (IADL) and depression. Malnutrition risk was prevalent and associated with poor appetite, functional status and psychosocial problems among the elderly subjects. The psychosocial aspect should also be incorporated in nutrition intervention programmes in order to improve mental well-being and functional independancy.

Tissue-specific variation in (CGG){sub n} repeat size and methylation status of the FMR1 gene was investigated in 17 female premutation carriers. Minor variation in premutation repeat size among leukocyte, lymphoblast, and fibroblast tissues was noted in some subjects. One subject exhibited a premutation size allele of (CGG){sub 64} in leukocyte and fibroblast tissues by polymerase chain reaction analysis but a normal-size allele of (CGG){sub 46} in lymphoblast cells, suggesting low-level mosaicism in blood and clonality of the lymphoblast cell line. Six subjects exhibited differences in methylation pattern between leukocytes and lymphoblasts but not between leukocytes and fibroblasts, whereas 2 subjectsmore » showed large differences in methylation pattern between leukocytes and fibroblasts. Cognitive function was studied in 14 subjects using the Wechsler Adult Intelligence Scale-Revised. Mean Verbal and Performance IQs were well within the average range as was the mean Full Scale IQ; nevertheless, a trend toward lower Performance IQ compared with Verbal IQ was observed. No significant correlation was apparent between Full Scale IQ and (CGG){sub n} repeat size; however, a significant positive correlation was observed between Full Scale IQ and the proportion of the active X carrying the normal FMR1 allele in fibroblasts but not in leukocytes or lymphoblasts. 24 refs., 1 fig., 2 tabs.« less

Parkinson's disease (PD) patients are more likely to develop impaired nutritional status because of the symptoms, medications and complications of the disease. However, little is known about the determinants and consequences of malnutrition in PD. This study aimed to investigate the association of motor, psychiatric and fatigue features with nutritional status as well as the effects of malnutrition on different aspects of quality of life (QoL) in PD patients. One hundred and fifty patients with idiopathic PD (IPD) were recruited in this study. A demographic checklist, the Unified Parkinson's Disease Rating Scale (UPDRS), the Hospital Anxiety and Depression Scale (HADS) and the Fatigue Severity Scale (FSS) were completed through face-to-face interviews and clinical examinations. The health-related QoL (HRQoL) was also evaluated by means of the Parkinson's Disease Questionnaire (PDQ-39). For evaluation of nutritional status, the Mini Nutritional Assessment (MNA) questionnaire was applied together with anthropometric measurements. Thirty seven (25.3%) patients were at risk of malnutrition and another 3 (2.1%) were malnourished. The total score of the UPDRS scale (r =  -0.613, P<0.001) and PD duration (r =  -0.284, P = 0.002) had a significant inverse correlation with the total MNA score. The median score of the Hoehn and Yahr stage was significantly higher in PD patients with abnormal nutritional status [2.5 vs. 2.0; P<0.001]. More severe anxiety [8.8 vs. 5.9; P = 0.002], depression [9.0 vs. 3.6; P<0.001] and fatigue [5.4 vs. 4.2; P<0.001] were observed in PD patients with abnormal nutritional status. Except for stigma, all other domains of the PDQ-39 were significantly correlated with the total score of the MNA. Our study demonstrates that disease duration, severity of motor and psychiatric symptoms (depression, anxiety) and fatigue are associated with nutritional status in PD. Different aspects of the HRQoL were affected by patients' nutritional status especially the emotional well-being and mobility domains.

The impact of parent education programs on early intervention programs is not thought to be uniform among children from majority and minority populations. This study examined the relationship between maternal childrearing practices and behaviors and the developmental status of Mexican-American infants. Participants were 62 Mexican-American mother-infant pairs. The infants' mean adjusted age was 12 months (SD=1.7, range=9-14). A third of the children were diagnosed with developmental delays and referred for early intervention by physicians or therapists when the children received their medical follow-up. The group was stratified according to socioeconomic status and acculturation using the Bidimensional Acculturation Scale for Hispanics. This scale uses cutoff points to classify individuals into 3 levels of acculturation. Information on childrearing practices and behaviors was gathered using the Parent Behavior Checklist (PBC), the Home Observation for Measurement of the Environment (HOME) Inventory, and the Nursing Child Assessment Teaching Scale (NCATS). Infants' developmental status was assessed by use of the Bayley Scales of Infant Development II (BSID II). The Pearson product moment correlation, partial correlations, Fisher z transformation, and multiple regression analyses were used to examine the relationship between childrearing practices and parenting behaviors, demographic factors, and infants' developmental status. Maternal nurturing behaviors, parent-child interaction, and quality of the home environment were positively correlated with the infants' cognitive development. Maternal years of education modified the observed relationship between PBC and BSID II scores but not the observed relationship between HOME Inventory and NCATS scores. The childrearing practices, maternal socioeconomic status (SES) and age, and infants' gestational age at birth (GA) explained 45% of the variance in infants' cognitive scores. The infants' GA, maternal SES and age, and NCATS scores accounted for 32% of the motor scores on the BSID II. The findings partially support a link between aspects of the mothers' childrearing behaviors and their infants' cognitive developmental status. For motor developmental status, the association appeared stronger with the infants' characteristics than with maternal childrearing practices and behaviors tested in this study.

The purposes of this study were to explore the effects of family cohesion and subjective happiness on death anxiety of Korean elders and to identify other factors contributing to death anxiety. The participants were 280 elders who lived in P metropolitan city. Data were collected between November 5, 2011 and January 12, 2012 using the Short Portable Mental Status Questionnaire (SPMSQ), Family Cohesion Evaluation Scale, Subjective Happiness Scale, and Fear of Death Scale (FODS). Data were analyzed using the SPSS/WIN 19.0 program. Family cohesion, marital status, religious activity, perceived health status, and subjective happiness were included in the factors affecting death anxiety of Korean elders. These variables explained 50.1% of death anxiety. The results of the study indicate that these variables should be considered in developing nursing intervention programs to decrease death anxiety and increase family cohesion and subjective happiness for life integration in Korean elders.

The purpose of the current study was to (a) examine the measurement invariance of the Constraint Scale of Sport Participation across sex and physical activity status among the undergraduate students (N = 630) in Hong Kong and (b) compare the latent mean differences across groups. Measurement invariance of the Constraint Scale of Sport Participation across sex of and physical activity status of the participants was examined first. With receiving support on the measurement invariance across groups, latent mean differences of the scores across groups were examined. Multi-group confirmatory factor analysis revealed that the configural, metric, scalar, and structural invariance of the scale was supported across groups. The results of latent mean differences suggested that the women reported significantly higher constraints on time, partner, psychology, knowledge, and interest than the men. The physically inactive participants reported significantly higher scores on all constraints except for accessibility than the physically active participants.

This work assessed the concurrent and face validity of the MacArthur scale, which attempts to capture subjective social status in society, neighborhood and work contexts. The study population comprised a convenience sample made up of 159 adult participants of the ELSA-Brasil cohort study conducted in Minas Gerais between 2012 and 2014. The analysis was conducted drawing on Conceptual Metaphor Theory and using corpus linguistic methods. Concurrent validity was shown to be moderate for the society ladder (Kappaw = 0.55) and good for the neighborhood (Kappaw = 0.60) and work (Kappaw = 0,67) ladders. Face validity indicated that the MacArthur scale really captures subjective social status across indicators of socioeconomic position, thus confirming that it is a valuable tool for the study of social inequalities in health Brazil.

Chemotherapy prolongs survival in patients with advanced non-small-cell lung cancer. However, few studies have included patients with poor performance status. This study examined rates of oncologists' recommendations for chemotherapy by patient performance status and symptoms and how physician characteristics influence chemotherapy recommendations. We surveyed medical oncologists involved in the care of a population-based cohort of patients with lung cancer from the CanCORS (Cancer Care Outcomes Research and Surveillance) study. Physicians were queried about their likelihood to recommend chemotherapy to patients with stage IV lung cancer with varying performance status (Eastern Cooperative Oncology Group performance status 0 [good] v 3 [poor]) and presence or absence of tumor-related pain. Repeated measures logistic regression was used to estimate the independent associations of patients' performance status and symptoms and physicians' demographic and practice characteristics with chemotherapy recommendations. Nearly all physicians (adjusted rate, 97% to 99%) recommended chemotherapy for patients with good performance status, and approximately half (adjusted rate, 38% to 53%) recommended chemotherapy for patients with poor performance status (P < .001). Compared with patient factors, physician and practice characteristics were less strongly associated with chemotherapy recommendations in adjusted analyses. Strong consensus among oncologists exists for chemotherapy in patients with advanced non-small-cell lung cancer and good performance status. However, the relatively high rate of chemotherapy recommendations for patients with poor performance status despite the unfavorable risk-benefit profile highlights the need for ongoing work to define high-value care in oncology and to implement and evaluate strategies to align incentives for such care.

The aim of this study was to assess the associations between coping mode, nutritional status, and psychological status and performance status of the patients with advanced stomach cancer. An epidemiological survey was conducted among 233 patients with advanced stomach cancer in Fujian, China. In-person interviews were performed for the participants with respect to information of psychological status prior to chemotherapy, nutritional status during chemotherapy, and physical performance status after chemotherapy. Multivariate logistic regression analyses showed that the level of hemoglobin (HB), level of daily calorie intake, score of Depression Status Inventory (DSI), and score of confrontation subscale of Medical Coping Modes Questionnaire had a significant influence on performance status (P < 0.05). The relative risks (95% confidence interval) were 2.06 (1.12-3.79) for low level of hemoglobin versus normal level of hemoglobin, 1.16 (1.02-1.32) for low level of daily calorie intake versus normal level of daily calorie intake, 5.89 (2.00-17.31) for DSI score > or =40 versus DSI score <40, and 3.17 (1.73-5.78) for low score of confrontation versus high score of confrontation, respectively. Depression, low score of "Confrontation", low levels of HB, and low level of daily calorie intake may be the risk factors of poor performance status of the patients with advanced stomach cancer.

Maternal perception of children's nutritional status in the Federal District, Brazil

Maternal perception of child's nutritional status has a potential impact on the identification, prevention, and treatment of childhood overweight. Thus, the aim of this study was to evaluate the prevalence of misperception and factors associated with maternal perception of the nutritional status of first- to third-grade elementary school students from private schools in the Federal District, Brazil. This cross-sectional study was conducted with 554 mother-child pairs. Children's nutritional status was assessed by measuring their weight and height. The mothers completed an online questionnaire about sociodemographic data, maternal nutritional status, maternal perception of her own nutritional status (silhouette scale for female adults), and maternal perception of child's nutritional status (silhouette scale for children). Only 30.0% of the mothers were successful in choosing the most appropriate silhouette to represent child's nutritional status. Highly educated mothers (Adjusted OR = 1.51) and mothers of male children (Adjusted OR = 2.53) or of non-overweight children (Adjusted OR = 1.65) were more likely to underestimate child's nutritional status. Conversely, mothers below 35 years of age (Adjusted OR = 1.85) and mothers of female children (Adjusted OR = 2.24) or of overweight children (Adjusted OR = 1.94) were more likely to overestimate child's nutritional status. There was a high prevalence of misperception, which shows the need for interventions for children that take into account the relevance of mother's role and the adequate recognition of child's nutritional status.

A cross-sectional survey was carried out in Ghinchi farming community, central Ethiopia during October and November 2001 to assess the level of association between children's nutritional status, families' socio-economic gradient, and degree of maternal attention and cognitive development. Ninety children were enrolled in the study, and assessment for cognitive performance was carried out using Bailey Infant Development Scale II. A pilot tested questionnaire was used to collect data on socio-economic status, mothers' care behavior, sanitary conditions of households and feeding pattern, and anthropometry of children. Chronic malnutrition expressed as height for age < -2Z-score of standard was prevalent beginning from the second birthday. Poor cognitive performance was comparatively common in the age group where chronic malnutrition is proportionately prevalent. Logistic regression analysis for variables that demonstrated significant association in correlation study revealed height for age, household possession of consumable durables, maternal care time, type and frequency of feeding and birth order of the child to be significant determinants for cognitive performance of children. Findings implicate a need for comprehensive approach, which incorporates, programs in nutrition, environmental sanitation, family planning, and strategies to reduce maternal workload, to ensure adequate physical and mental development of children.

While the personality dimensions of novelty seeking and sensation seeking are associated with drug abuse vulnerability, the mechanisms associated with this vulnerability remain obscure. This study examined the behavioral effects of d-amphetamine in healthy volunteers scoring in the upper and lower quartiles based on age- and gender-adjusted population norms on the impulsive Sensation-Seeking Scale (SSS) of the Zuckerman-Kuhlman personality questionnaire (ZKPQ). Participants completed 7-day outpatient studies examining the subjective, performance, and cardiovascular effects of d-amphetamine (0, 7.5, and 15 mg/70 kg, p.o.) under double-blind conditions according to a randomized block design. Performance tasks included behavioral measures of impulsivity, including attention, inhibition, and risk-taking behavior. No differences in baseline performance or d-amphetamine effects on measures of attention, inhibition, and risk-taking behavior were observed. High impulsive sensation seekers reported greater increases on several subjective report measures associated with drug abuse potential, including visual analog scales feel drug, like drug, and high. Healthy adults scoring in the top quartile on the population of the impulsive SSS of the ZKPQ may be vulnerable to the abuse potential of d-amphetamine.

To examine the relationship between health literacy (HL), health information access, health behavior, and health status in Japanese people. A questionnaire survey was conducted at six healthcare facilities in Japan. Eligible respondents aged 20-64 years (n=1218) were included. Path analysis with structural equation modeling was performed to test the hypothesis model linking HL to health information access, health behavior, and health status. The acceptable fitting model indicated that the pathways linking HL to health status consisted of two indirect paths; one intermediated by health information access and another intermediated by health behavior. Those with higher HL as measured by the 14-item Health Literacy Scale (HLS-14) were significantly more likely to get sufficient health information from multiple sources, less likely to have risky habits of smoking, regular drinking, and lack of exercise, and in turn, more likely to report good self-rated health. HL was significantly associated with health information access and health behavior in Japanese people. HL may play a key role in health promotion, even in highly educated countries like Japan. In order to enhance the effects of health promotion interventions, health professionals should aim at raising HL levels of their target population groups. Copyright © 2015 Elsevier Ireland Ltd.

The prevalence, characteristics, and impact of pain and other symptoms have not been studied systematically in women with ovarian cancer. Anecdotally, pain has been associated with the onset of the disease and is a common problem among those with advanced cancer; symptoms other than pain appear to be highly prevalent. Given the profound influence of pain and other symptoms on quality of life, the evaluation of these phenomena could provide data relevant to the clinical management of these patients and advance quality of life research in the area of symptom assessment. Questionnaires were completed by 111 inpatients and 40 outpatients with ovarian cancer who were undergoing treatment at a cancer center. Measures included a comprehensive pain questionnaire; the Rand Mental Health Inventory, Functional Living Index--Cancer; and the Memorial Symptom Assessment Scale. The sample (N = 151) represented 74% of the eligible patients. The median age was 55 years (range, 23-86), 82% had Stage III or IV disease at presentation, and 69% had active disease at the time of the survey. Pain, fatigue, and psychologic distress were the most prevalent symptoms. Sixty-two percent (N = 94) described a pain syndrome that preceded the onset or recurrence of the disease, and 42% (N = 63) reported "persistent or frequent pain" during the preceding 2 weeks. The latter pain had a median duration of 2 weeks (range, less than 1 to 756 weeks) and usually was in the abdominopelvic region (80%), frequent or almost constant (66%), and moderate to severe. Most patients reported moderate or greater pain-related interference with various aspects of function, particularly activity (68%), mood (62%), work (62%), and overall enjoyment of life (61%). Performance status, inpatient status, and unmarried status were significant predictors of pain presence or intensity, and both performance status and extent of tumor were significant predictors of pain interference with function. Among those with ovarian cancer, greater than 40% experienced pain that substantially undetermined function in one half to two thirds of these patients. Impaired performance status is associated most strongly with pain. The onset or recurrence of disease often is heralded by a stereotypic pain syndrome.

The MAJORANA DEMONSTRATOR will search for neutrinoless-double-beta decay (0νββ) in 76Ge, while establishing the feasibility of a future tonne-scale germanium-based 0νββ experiment, and performing searches for new physics beyond the Standard Model. The experiment, currently under construction at the Sanford Underground Research Facility in Lead, SD, will consist of a pair of modular high-purity germanium detector arrays housed inside of a compact copper, lead, and polyethylene shield. Through a combination of strict materials qualifications and assay, low-background design, and powerful background rejection techniques, the Demonstrator aims to achieve a background rate in the 0νββ region of interest (ROI) of no more than 3 counts in the 0νββ-decay ROI per tonne of target isotope per year (cnts/(ROI-t-y)). The current status of the Demonstrator is discussed, as are plans for its completion.

The present study is an open-label extension (OLE) aimed at evaluating the effect of 100 mg/day of phosphatidylserine enriched with docosahexaenoic acid (PS-DHA) on cognitive performance in nondemented elderly individuals with memory complaints. From the participants who completed the core study, 122 continued with a 15-week OLE. Efficacy was assessed using a computerized tool and the Clinical Global Impression of Change (CGI-C) rating scale. A significant improvement in sustained attention and memory recognition was observed in the PS-DHA naïve group, while the PS-DHA continuers maintained their cognitive status. Additionally, a significant improvement in CGI-C was observed in the naïve group. The results demonstrate that consumption of 100 mg/day of PS-DHA might be associated with improving or maintaining cognitive status in elderly subjects with memory complaints.

To examine the relationship between employment status (no employment, part-time employment, and full-time employment) and functional disability, health-related quality of life, and life satisfaction of people with MS. 157 individuals with MS completed a survey packet, including employment status, self-report disability severity, and health-related scales. A series of multivariate analysis of variance was performed to determine the differences between employment groups in health-related outcomes. The unemployed group had the highest levels of incapacity and social impairments among the three groups. They also had the lowest physical health-related quality of life and life satisfaction. The part-time employed group had the lowest levels of depression and higher levels of physical activity participation among the three groups of individuals with MS. Employment is significantly related to health-related quality of life, and as a result, it should be considered an important public health intervention for people with MS.

How much do our choices represent stable inner preferences versus social conformity? We examine conformity and consistency in sartorial choices surrounding a common life event of new norm exposure: relocation. A large-scale dataset of individual purchases of women's shoes (16,236 transactions) across five years and 2,007 women reveals a balance of conformity and consistency, moderated by changes in location socioeconomic status. Women conform to new local norms (i.e., average heel size) when moving to relatively higher status locations, but mostly ignore new local norms when moving to relatively lower status locations. In short, at periods of transition, it is the fashion norms of the rich that trickle down to consumers. These analyses provide the first naturalistic large-scale demonstration of the tension between psychological conformity and consistency, with real decisions in a highly visible context.

Carpal tunnel syndrome (CTS) is recognized as the most common type of neuropathies. Questionnaires are the method of choice for evaluating patients with CTS. Boston Carpal Tunnel Syndrome (BCTS) is one of the most famous questionnaires that evaluate the functional and symptomatic aspects of CTS. This study was performed to evaluate the validity and reliability of the Persian version of BCTS questionnaire. First, both parts of the original questionnaire (Symptom Severity Scale and Functional Status Scale) were translated into Persian by two expert translators. The translated questionnaire was revised after merging and confirmed by an orthopedic hand surgeon. The confirmed questionnaire was interpreted back into the original language (English) to check for any possible content inequality between the original questionnaire and its final translated version. The final Persian questionnaire was answered by 10 patients suffering from CTS to elucidate its comprehensibility; afterwards, it was filled by 142 participants along with the Persian version of the Quick-DASH questionnaire. After 2 to 6 days, the translated questionnaire was refilled by some of the previous patients who had not received any substantial medical treatment during that period. Among all 142 patients, 13.4 % were male and 86.6 % were female. The reliability of the questionnaire was tested using Cronbach's alpha and Intraclass correlation coefficient (ICC). Cronbach's alpha was 0.859 for symptom severity scale (SSS) and 0.878 for functional status scale (FSS). Also, ICCs were calculated as 0.538 for SSS and 0.773 for FSS. In addition, construct validity of SSS and FSS against QuickDASH were 0.641 and 0.701, respectively. Based on our results, the Persian version of the BCTQ is valid and reliable. Level of evidence: II.

To obtain reliability and applicability of the Korean version Bayley Scale of Infant Development-II (BSID-II) in evaluating the developmental status of children with cerebral palsy (CP). The inter-rater reliability of BSID-II scores from 68 children with CP (46 boys and 22 girls; mean age, 32.54±16.76 months; age range, 4 to 78 months) was evaluated by 10 pediatric occupational therapists. Patients were classified in several ways according to age group, typology, and the severity of motor impairment by the level of the Gross Motor Function Classification System (GMFCS). The measures were performed by video analysis, and the results of intraclass correlation (ICC) were obtained for each of the above classifications. To evaluate the clinical applicability of BSID-II for CP, its correlation with the Gross Motor Function Measure (GMFM), which has been known as the standard motor assessment for CP, was investigated. ICC was 0.99 for the Mental scale and 0.98 for the Motor scale in all subjects. The values of ICC ranged from 0.92 to 0.99 for each age group, 0.93 to 0.99 for each typology, and 0.99 to 1.00 for each GMFCS level. A strong positive correlation was found between the BSID-II Motor raw score and the GMFM total score (r=0.84, p<0.001), and a moderate correlation was observed between the BSID-II Mental raw score and the GMFM total score (r=0.65, p<0.001). The Korean version of BSID-II is a reliable tool to measure the functional status of children with CP. The raw scores of BSID-II showed a great correlation with GMFM, indicating validity of this measure for children with CP on clinical basis.

Use of the Progressive Aphasia Severity Scale (PASS) in monitoring speech and language status in PPA

2014-01-01

Background Primary progressive aphasia (PPA) is a devastating neurodegenerative syndrome involving the gradual development of aphasia, slowly impairing the patient’s ability to communicate. Pharmaceutical treatments do not currently exist and intervention often focuses on speech-language behavioral therapies, although further investigation is warranted to determine how best to harness functional benefits. Efforts to develop pharmaceutical and behavioral treatments have been hindered by a lack of standardized methods to monitor disease progression and treatment efficacy. Aims Here we describe our current approach to monitoring progression of PPA, including the development and applications of a novel clinical instrument for this purpose, the Progressive Aphasia Severity Scale (PASS). We also outline some of the issues related to initial evaluation and longitudinal monitoring of PPA. Methods & Procedures In our clinical and research practice we perform initial and follow-up assessments of PPA patients using a multi-faceted approach. In addition to standardized assessment measures, we use the PASS to rate presence and severity of symptoms across distinct domains of speech, language, and functional and pragmatic aspects of communication. Ratings are made using the clinician’s best judgment, integrating information from patient test performance in the office as well as a companion’s description of routine daily functioning. Outcomes & Results Monitoring symptom characteristics and severity with the PASS can assist in developing behavioral therapies, planning treatment goals, and counseling patients and families on clinical status and prognosis. The PASS also has potential to advance the implementation of PPA clinical trials. Conclusions PPA patients display heterogeneous language profiles that change over time given the progressive nature of the disease. The monitoring of symptom progression is therefore crucial to ensure that proposed treatments are appropriate at any given stage, including speech-language therapy and potentially pharmaceutical treatments once these become available. Because of the discrepancy that can exist between a patient’s daily functioning and standardized test performance, we believe a comprehensive assessment and monitoring battery must include performance-based instruments, interviews with the patient and partner, questionnaires about functioning in daily life, and measures of clinician judgment. We hope that our clinician judgment-based rating scale described here will be a valuable addition to the PPA assessment and monitoring battery. PMID:25419031

Small-scale urban dairy farms (n = 16) in and around Jimma, Ethiopia with cross-bred (Bos indicus × Bos taurus) cows were enrolled in a double-blinded intervention study to investigate the effect of a trace element supplementation programme on trace element status and milk concentrations as well as performance [body condition score (BCS), milk yield, leptin], milk composition, antioxidant status (ferric-reducing ability of plasma (FRAP), thiobarbituric acid-reactive substances (TBARS)], blood biochemistry, serum proteins and immune response (antibody titre upon rabies vaccination). The farms were allocated to a (1) placebo or (2) Cu, Zn, Se, Co and I supplementation treatment for 150 d. On days 0 and 120, four lactating cows per farm were sampled for milk and plasma, and on day 150 for serum, following primo-vaccination. Cu deficiency was present in 17% and marginal Se deficiency in 30% of initially sampled cows, while no Zn shortage was detected. Over 120 days, trace element supplementation caused a bigger increase in plasma Se and Cu concentrations, but also a larger decrease of plasma Fe concentrations. A larger increase in milk Se concentrations was observed in the supplemented group, whereas none of the other elements were affected. BCS decreased more over time in the supplemented group. None of the other parameters of performance and antioxidant status nor milk composition or blood biochemistry was affected by treatment. Antibody response to rabies vaccination did not differ between groups, whereas α1-globulins tended to be lower and β-globulins tended to be higher in the supplemented group. In conclusion, despite improved Cu and Se status and Se concentrations in milk, cows on tropical urban dairy farms did not seem to benefit from trace element supplementation, with respect to the parameters investigated.

The purpose of this descriptive correlational study was to identify knowledge levels and performance frequency of breast self-examination (BSE) and to examine variables related to breast cancer screening behaviors in a sample of Turkish women. Data were collected from a convenience sample of 103 Muslim female workers at a hazelnut factory in Ordu city, Turkey, using an adapted version of Champion's revised Health Belief Model Scale. Results showed that 26.2% of the women reported knowledge of BSE and 4.3% reported that they perform BSE. Higher health motivation, higher perceived self-efficacy of BSE, marital status, and familial breast cancer history were significantly associated with BSE performance. Higher levels of health motivation and higher perceived self-efficacy of BSE were also significantly associated with knowledge of BSE.

Purpose Prophylactic cranial irradiation (PCI) in patients with extensive-disease small-cell lung cancer (ED-SCLC) leads to significantly fewer symptomatic brain metastases and improved survival. Detailed effects of PCI on health-related quality of life (HRQOL) are reported here. Patients and Methods Patients (age, 18 to 75 years; WHO ≤ 2) with ED-SCLC, and any response to chemotherapy, were randomly assigned to either observation or PCI. Health-related quality of life (HRQOL) and patient-reported symptoms were secondary end points. The European Organisation for the Research and Treatment of Cancer core HRQOL tool (Quality of Life Questionnaire C30) and brain module (Quality of Life Questionnaire Brain Cancer Module) were used to collect self-reported patient data. Six HRQOL scales were selected as primary HRQOL end points: global health status; hair loss; fatigue; and role, cognitive and emotional functioning. Assessments were performed at random assignment, 6 weeks, 3 months, and then 3-monthly up to 1 year and 6-monthly thereafter. Results Compliance with the HRQOL assessment was 93.7% at baseline and dropped to 60% at 6 weeks. Short-term results up to 3 months showed that there was a negative impact of PCI on selected HRQOL scales. The largest mean difference between the two arms was observed for fatigue and hair loss. The impact of PCI on global health status as well as on functioning scores was more limited. For global health status, the observed mean difference was eight points on a scale 0 to 100 at 6 weeks (P = .018) and 3 months (P = .055). Conclusion PCI should be offered to all responding ED SCLC patients. Patients should be informed of the potential adverse effects from PCI. Clinicians should be alert to these; monitor their patients; and offer appropriate support, clinical, and psychosocial care. PMID:19047288

The relations of Gf (Standard Progressive Matrices Raven), Gc (verbal scale of Wechsler Intelligence Scale for Children-Third Version), personality dimensions (Eysenck Personality Questionnaire-Junior Version), and disruptive behavior (TDAH scale) with school achievement (measured by TDE test and PISA test) were investigated. Two samples of students (total N = 534) representing a broad range of socioeconomic status (SES) participated in this study. Path models were conducted. The results demonstrated that (1) in both samples no sex differences related to school achievement were found; (2) in the first sample, after controlling for age and SES differences, Gf and psychoticism predicted (.38 and -.13, respectively) school achievement (measured by TDE test); (3) in the second sample, after controlling for SES differences to which additional measures were administered, Gf and Gc positively predicted (.22 and .40, respectively) school achievement (measured by PISA test). In addition, psychoticism and disruptive behavior also predicted school performance (-.14 and -.28, respectively). Some theoretical and practical implications are discussed.

The Botswana water and surface energy balance research program was developed to study and evaluate the integrated use of multispectral satellite remote sensing for monitoring the hydrological status of the Earth's surface. The research program consisted of two major, mutually related components: a surface energy balance modeling component, built around an extensive field campaign; and a passive microwave research component which consisted of a retrospective study of large scale moisture conditions and Nimbus scanning multichannel microwave radiometer microwave signatures. The integrated approach of both components are explained in general and activities performed within the passive microwave research component are summarized. The microwave theory is discussed taking into account: soil dielectric constant, emissivity, soil roughness effects, vegetation effects, optical depth, single scattering albedo, and wavelength effects. The study site is described. The soil moisture data and its processing are considered. The relation between observed large scale soil moisture and normalized brightness temperatures is discussed. Vegetation characteristics and inverse modeling of soil emissivity is considered.

The sense of coherence (SOC) has been suggested to be highly applicable concept in the public health area because a strong SOC is stated to decrease the likelihood of perceiving the social environment as stressful. This reduces the susceptibility to the health-damaging effect of chronic stress by lowering the likelihood of repeated negative emotions to stress perception. The demographic data and general information of subjects' oral health behaviors such as frequency of cleaning teeth, aids used to clean teeth, and dental attendance were recorded in the self-administered questionnaire. The SOC-related data were obtained using the short version of Antonovsky's SOC scale. The periodontal status was recorded based on the modified World Health Organization 1997 pro forma. The total of 780 respondents comprising 269 (34.5%) males and 511 (65.5%) females participated in the study. A significant difference was noted among the subjects for socioeconomic status based on gender ( P = 0.000). The healthy periodontal status (community periodontal index [CPI] code 0) was observed for 67 (24.9%) males and 118 (23.1%) females. The overall SOC showed statistically negative correlation with socioeconomic status scale ( r = -0.287). The CPI and loss of attachment (periodontal status) were significantly and negatively correlated with SOC. The present study concluded that a high level of SOC was associated with good oral health behaviors, periodontal status, and socioeconomic status.

MPD (MagnetoPlasmaDynamic) thrusters demonstrated between 2000 and 7000 seconds specific impulse at efficiencies approaching 40 percent, and were operated continuously at power levels over 500 kW. These demonstrated capabilities, combined with the simplicity and robustness of the thruster, make them attractive candidates for application to both unmanned and manned orbit raising, lunar, and planetary missions. To date, however, only a limited number of thruster configurations, propellants, and operating conditions were studied. The present status of MPD research is reviewed, including developments in the measured performance levels and electrode erosion rates. Theoretical studies of the thruster dynamics are also described. Significant progress was made in establishing empirical scaling laws, performance and lifetime limitations and in the development of numerical codes to simulate the flow field and electrode processes.

Adaptive behavior can be impaired in different neurodevelopmental disorders and may be influenced by confounding factors, such as intelligence quotient (IQ) and socioeconomic classification. Our main objective was to verify whether adaptive behavior profiles differ in three conditions-Williams Beuren syndrome (WBS), Down syndrome (DS), and autism spectrum disorder (ASD), as compared with healthy controls (HC) and with each other. Although the literature points towards each disorder having a characteristic profile, no study has compared profiles to establish the specificity of each one. A secondary objective was to explore potential interactions between the conditions and socioeconomic status, and whether this had any effect on adaptive behavior profiles. One hundred and five adolescents were included in the study. All adolescents underwent the following evaluations: the Vineland Adaptive Behavior Scale (VABS), the Wechsler Intelligence Scale for Children (WISC), and the Brazilian Economic Classification Criteria. Our results demonstrated that the WBS group performed better than the DS group in the communication domain, β = -15.08, t(3.45), p = .005, and better than the ASD group in the socialization domain, β = 8.92, t(-2.08), p = .013. The DS group also performed better than the ASD group in socialization, β = 16.98, t(-2.32), p = .024. IQ was an important confounding factor, and socioeconomic status had an important effect on the adaptive behavior of all groups. There is a heterogeneity regarding adaptive behavior profiles in WBS, DS, and ASD. These data are important to better design specific strategies related to the health and social care of each particular group.

In general population samples, better childhood cognitive functioning is associated with decreased risk of depression in adulthood. However, this link has not been examined in extremely low birth weight survivors (ELBW, <1000 g), a group known to have poorer cognition and greater depression risk. This study assessed associations between cognition at age 8 and lifetime risk of major depressive disorder in 84 ELBW survivors and 90 normal birth weight (NBW, ⩾2500 g) individuals up to 29-36 years of age. The Wechsler Intelligence Scale for Children, Revised (WISC-R), Raven's Coloured Progressive Matrices and the Token Test assessed general, fluid, and verbal intelligence, respectively, at 8 years of age. Lifetime major depressive disorder was assessed using the Mini International Neuropsychiatric Interview at age 29-36 years. Associations were examined using logistic regression adjusted for childhood socioeconomic status, educational attainment, age, sex, and marital status. Neither overall intelligence quotient (IQ) [WISC-R Full-Scale IQ, odds ratios (OR)=0.87, 95% confidence interval (CI)=0.43-1.77], fluid intelligence (WISC-R Performance IQ, OR=0.98, 95% CI=0.48-2.00), nor verbal intelligence (WISC-R Verbal IQ, OR=0.81, 95% CI=0.40-1.63) predicted lifetime major depression in ELBW survivors. However, every standard deviation increase in WISC-R Full-Scale IQ (OR=0.43, 95% CI=0.20-0.92) and Performance IQ (OR=0.46, 95% CI=0.21-0.97), and each one point increase on the Token Test (OR=0.80, 95% CI=0.67-0.94) at age 8 was associated with a reduced risk of lifetime depression in NBW participants. Higher childhood IQ, better fluid intelligence, and greater verbal comprehension in childhood predicted reduced depression risk in NBW adults. Our findings suggest that ELBW survivors may be less protected by superior cognition than NBW individuals.

MOF-derived nanohybrids for electrocatalysis and energy storage: current status and perspectives.

More than 20 000 MOFs have been reported to date, with different combinations of metal ions/centers and organic linkers, and they can be grown into various 3D, 2D, 1D and 0D morphologies. The flexibility in control over varying length scales from atomic scale up to bulk structure allows access to an almost endless variety of MOF-based and MOF-derived materials. Indeed, MOFs themselves have been studied as a class of useful functional materials. More remarkably, extensive research conducted in recent years has shown that MOFs are exceptionally good precursors for a large variety of nanohybrids as active materials in both electrocatalysis and energy storage. As they already contain both carbon and well-dispersed metal atoms, MOFs can be converted to conductive carbons decorated with active metal species and doping elements through appropriate pyrolysis. Due to the great diversity accessible in the composition, structure, and morphology of MOFs, several types of MOF-derived nanohybrids are now among the best performing materials both for electrocatalysts and electrodes in various energy conversion and storage devices. In addition to mesoporous nano-carbons, both doped and undoped, carbon-metal nanohybrids, and carbon-compound nanohybrids, there are several types of core@shell, encapsulated nanostructures, embedded nanosystems and heterostructures that have been developed from MOFs recently. They can be made in either free-standing forms, nano- or micro-powders, grown on appropriate conducting substrates, or assembled together with other active materials. During the MOF to active material conversion, other active species or precursors can be inserted into the MOF-derived nanostructures or assembled on surfaces, leading to uniquely new porous nanostructures. These MOF-derived active materials for electrocatalysis and energy storage are nanohybrids consisting of more than functional components that are purposely integrated together at desired length scales for much-improved performance. This article reviews the current status of these nanohybrids and concludes with a brief perspective on the future of MOF-derived functional materials.

Method: Clinical assessment of dysphagia partially using the Protocol of Risk Assessment for Dysphagia (PARD), applying the scale Functional Oral Intake Scale for Dysphagia in Stroke Patients (FOIS), Beck Anxiety Inventory (BAI) and the Mini Nutritional Assessment MNA®. The sample consisted of 12 patients, mean age of 64.6 years, with a medical diagnosis of hemorrhagic and ischemic stroke and without cognitive disorders. All tests were applied before and after speech therapy (15 sessions). Statistical analysis was performed using the chi-square test or Fisher's exact test, McNemar's test, Bowker's symmetry test and Wilcoxon's test. Results: During the pre-speech therapy assessments, 33.3% of patients had mild to moderate dysphagia, 88.2% did not receive food orally, 47.1% of the patients showed malnutrition and 35.3% of patients had mild anxiety level. After the therapy sessions, it was found that 33.3% of patients had mild dysphagia, 16.7% were malnourished and 50% of patients had minimal level of anxiety. Conclusion:  There were statistically significant evolution of the level of dysphagia (p = 0.017) and oral intake (p = 0.003) post-speech therapy. Although not statistically significant, there was considerable progress in relation to the level of anxiety and nutritional status. PMID:25992086

Hypertension and cervical spondylosis are diseases of the adult population that are approaching near pandemic proportions. However, the interactions between these two disease processes are poorly understood. We set out to determine the associations among systemic hypertension, clinical status, and imaging findings of spinal cord damage for patients with cervical stenosis. A retrospective chart review was performed on patients with symptomatic cervical stenosis related to degenerative disease and divided on the basis of outpatient blood pressure control (normal <140/<90 mm Hg). Sagittal T2-weighted magnetic resonance imaging (MRI) of the cervical spine was analyzed to determine the degree of maximal canal stenosis (MCS; %), surface area of increased signal intensity (ISI; cm(2)), and signal intensity ratio (SIR). Functional status was evaluated using the modified Japanese Orthopaedic Association (mJOA) scale and the Nurick scale. One hundred twenty-two patients were identified (64 hypertensive, 58 nonhypertensive). Likelihood of ISI was higher in hypertensive patients (P < 0.05). Average ISI was significantly higher in patients with uncontrolled blood pressure (P = 0.02) despite MCS being identical between the two groups. The mJOA and Nurick scores were worse for patients with systemic hypertension (P < 0.02). Diabetes mellitus and smoking history did not affect these findings. Persistent hypertension in outpatients is associated with worsened clinical status and increased markers of spinal cord damage on MRI. Perioperative management of blood pressure may serve to improve clinical outcomes. Larger prospective trials are necessary to further validate these findings. Copyright © 2015 Elsevier Inc.

Background Polygonum minus (PM) or locally known in Malaysia, as “kesum” is rich in micronutrients and natural antioxidants. However, its beneficial effect on outcome associates with oxidative stress including cognitive function is yet to be discovered. We assessed the efficacy of PM extract (LineMinus™) on cognitive function and psychosocial status among middle-aged women in Klang Valley of Malaysia. Methods A randomized, double-blind, placebo-controlled trial among 35 healthy middle-aged women was performed, and subjects were randomized to receive either 250 mg PM or placebo of 100 mg maltodextrin each were taken twice daily for 6 weeks. Subjects were assessed for neuropsychological test, psychosocial status, and anthropometric at baseline, week 3, and week 6. Biomarkers were also determined at baseline and week 6. Results The supplementation of PM showed significant intervention effect on Digit Span test (P<0.05) social functioning domain of 36-Item Short Form Health Survey (P<0.05) among subjects with mood disturbance. While, among subjects with good mood, PM supplementation improved Wechsler Abbreviated Scale of Intelligence (WASI) for IQ verbal (P=0.016) and Full Scale IQ of WASI (P=0.004). There were no adverse effects reported for the supplementation as indicated using biomarkers, including liver function and clinical symptoms. Conclusion Supplementation of PM is safe to be consumed for 6 weeks, with potential benefits to attention, short-term memory, improved quality of life, and mood, as well as IQ. PMID:26445532

This study published in two companion papers assesses properties of the Mini-Mental State Examination (MMSE) with the purpose of improving the efficiencies of the methods of screening for cognitive impairment and dementia. An item analysis by conventional and mixed Rasch models was used to explore empirically derived cognitive dimensions of the MMSE, to assess item bias, and to construct diagnostic cut-points. The scores of 1,189 elderly residents were analyzed. Two dimensions of cognitive function, which are statistically and conceptually different from those obtained in previous studies, were derived. The corresponding sum scales were (1) age-correlated MMSE scale (A-MMSE scale: orientation to time, attention/calculation, naming, repetition, and three-stage command) and (2) non-age-correlated MMSE scale (B-MMSE scale: orientation to place, registration, recall, reading, and copying). The "writing" item was not included due to differential effects of age and sex. The analysis also showed that the study sample consisted of two cognitively different groups of elderly. The findings indicate that a two-scale solution is a stable and statistically supported framework for interpreting data obtained by means of the MMSE. Supplementary analyses are presented in the companion paper to explore the performance of this item response theory calibration as a screening test for dementia.

Will COBE challenge the inflationary paradigm - Cosmic microwave background anisotropies versus large-scale streaming motions revisited

Gorski, K.M.

1991-03-01

The relation between cosmic microwave background (CMB) anisotropies and large-scale galaxy streaming motions is examined within the framework of inflationary cosmology. The minimal Sachs and Wolfe (1967) CMB anisotropies at large angular scales in the models with initial Harrison-Zel'dovich spectrum of inhomogeneity normalized to the local large-scale bulk flow, which are independent of the Hubble constant and specific nature of dark matter, are found to be within the anticipated ultimate sensitivity limits of COBE's Differential Microwave Radiometer experiment. For example, the most likely value of the quadrupole coefficient is predicted to be a2 not less than 7 x 10 tomore » the -6th, where equality applies to the limiting minimal model. If (1) COBE's DMR instruments perform well throughout the two-year period; (2) the anisotropy data are not marred by the systematic errors; (3) the large-scale motions retain their present observational status; (4) there is no statistical conspiracy in a sense of the measured bulk flow being of untypically high and the large-scale anisotropy of untypically low amplitudes; and (5) the low-order multipoles in the all-sky primordial fireball temperature map are not detected, the inflationary paradigm will have to be questioned. 19 refs.« less

In this article, the authors present a microeconomic analysis of the effects of the administrative status on plastic surgery units within academic medical centers, comparing the departmental versus subdepartmental status. The objectives are to introduce decision-making tools of microeconomics and use them to explore the potential effects of administrative status on academic plastic surgery services. Real financial data over a decade were used to construct total cost (TC), average total cost (ATC), and total revenue (TR) curves. From these, the authors derive the efficiency scale and express the fiscal performance by examining profitability, and the commonly used ATC curve. Mathematical modeling is then used to examine the effects of departmental versus subdepartmental status, assuming that (1) a plastic surgery unit exists in a competitive market; and (2) TR > TC for the plastic surgery unit to self-sustain in the long term. The variables considered are total clinical production (Q), gross collection rates (GCR), personnel cost, and departmental tax. The sustainability (Q against GCR) is a hyperbolic curve with Q × GCR = TC at break-even. The TC/TR = f(TR) curve resembles the ATC curve. Sectional versus departmental status for a plastic surgery service in an academic medical center depends greatly on the shape of their TC/TR = f(TR) curve. With most competing clinical units within the same academic medical center having departmental status, and most competing private surgeons having no institutional "taxes," the essential requirement for academic medical center plastic surgery services is to ensure that their TC/TR = f(TR) curve is comparable to that of their competitors.

Whole-body cryostimulation (cryotherapy) provides benefits for fatigue and functional status in multiple sclerosis patients. A case-control study.

To study the effects of whole-body cryostimulation (WBC) on fatigue and functional status in multiple sclerosis (MS) patients with different levels of fatigue. Two groups of 24 MS patients with fatigue were studied. At the beginning of the study, the first group presented a Fatigue Severity Scale (FSS) score between 38 and 42 (low-fatigue (LF) group), and the second group had an FSS score between 48 and 52 (high-fatigue (HF) group). Both groups were matched for age and sex. All patients were exposed to 10.3-min session of WBC (one exposure per day at -110°C or lower). Functional status was assessed before and after the series of WBC exposures using the Rivermead Motor Assessment (RMA), the Multiple Sclerosis Impact Scale (MSIS-29), and the Expanded Disability Status Scale (EDSS). The RMA was estimated in three sections: gross function (RMA1), leg and trunk (RMA2), and arm (RMA3). MSIS-29 consists of two subscales assessing the physical (MSIS-29-PHYS) and psychological (MSIS-29-PSYCH) status. In both groups, the WBC sessions induced a significant improvement in the functional status and in the feeling of fatigue. However, the changes observed in HF patients were significantly greater than those observed in LF patients, especially in the MSIS-29-PHYS, MSIS-29-PSYCH, RMA1, and RMA3. The changes observed in the EDSS, RMA2, and FSS were similar in both groups. WBC appears to be effective in improving functional status and the feeling of fatigue in patients with MS and especially in those who are the most fatigued. © 2016 John Wiley & Sons A/S.

The Effects of Specialization and Sex on Anterior Y-Balance Performance in High School Athletes.

PubMed

Miller, Madeline M; Trapp, Jessica L; Post, Eric G; Trigsted, Stephanie M; McGuine, Timothy A; Brooks, M Alison; Bell, David R

Sport specialization and movement asymmetry have been separately discussed as potential risk factors for lower extremity injury. Early specialization may lead to the development of movement asymmetries that can predispose an athlete to injury, but this has not been thoroughly examined. Athletes rated as specialized would exhibit greater between-limb anterior reach asymmetry and decreased anterior reach distance on the Y-balance test (YBT) as compared with nonspecialized high school athletes, and these differences would not be dependent on sex. Cross-sectional study. Level 3. Two hundred ninety-five athletes (117 male, 178 female; mean age, 15.6 ± 1.2 years) from 2 local high schools participating in basketball, soccer, volleyball, and tennis responded to a questionnaire regarding sport specialization status and performed trials of the YBT during preseason testing. Specialization was categorized according to 3 previously utilized specialization classification methods (single/multisport, 3-point scale, and 6-point scale), and interactions between specialization and sex with Y-balance performance were calculated using 2-way analyses of variance. Single-sport male athletes displayed greater anterior reach asymmetry than other interaction groups. A consistent main effect was observed for sex, with men displaying greater anterior asymmetry and decreased anterior reach distance than women. However, the interaction effects of specialization and sex on anterior Y-balance performance varied based on the classification method used. Single-sport male athletes displayed greater anterior reach asymmetry on the YBT than multisport and female athletes. Specialization classification method is important because the 6- and 3-point scales may not accurately identify balance abnormalities. Male athletes performed worse than female athletes on both of the Y-balance tasks. Clinicians should be aware that single-sport male athletes may display deficits in dynamic balance, potentially increasing their risk of injury.

The status of the Dynamic Scale Model Technology (DSMT) research program is presented. DSMT is developing scale model technology for large space structures as part of the Control Structure Interaction (CSI) program at NASA Langley Research Center (LaRC). Under DSMT a hybrid-scale structural dynamics model of Space Station Freedom was developed. Space Station Freedom was selected as the focus structure for DSMT since the station represents the first opportunity to obtain flight data on a complex, three-dimensional space structure. Included is an overview of DSMT including the development of the space station scale model and the resulting hardware. Scaling technology was developed for this model to achieve a ground test article which existing test facilities can accommodate while employing realistically scaled hardware. The model was designed and fabricated by the Lockheed Missile and Space Co., and is assembled at LaRc for dynamic testing. Also, results from ground tests and analyses of the various model components are presented along with plans for future subassembly and matted model tests. Finally, utilization of the scale model for enhancing analysis verification of the full-scale space station is also considered.

The Empathy (E) scale has been proposed as a theoretically and psychometrically more satisfying alternative to existing self-report measures of empathy. Its four scales (facets) cover both components (cognitive vs. emotional) and both reality statuses (fictitious vs. real-life) of empathy in pairwise combinations. Confirmatory factor analyses of the E-scale in an Austrian community sample (N = 794) suggested that one prior assumption, namely the mutual orthogonality of these facets, may partly need revision; particularly, the E-scale facets seemed to reflect more strongly differences in the reality statuses than in the components of empathy. Utilizing numerous informative psychological traits, the scale's convergent and discriminant validity were examined. E-scale scores were consistently predicted by sex-related and relationship-related constructs and measures of antisocial attitudes and behavior. Among the Big Five personality dimensions, openness emerged as a major positive correlate of empathy. Sex and age were demographic correlates of E-scale scores (higher in women and the younger). Findings were discussed with regards to the definition and measurement of empathy.

This study analyzes the relationship between gender and self-perceived health status in Spanish retirees and housewives from a sample of 1,106 community-dwelling older adults. A multivariate linear regression model was used in which self-perceived health status was measured by the EQ-5D visual analogue scale and gender according to work status (retired men and women and housewives). Retired males reported a significantly better health status than housewives. Self-perceived health status was closely associated with physical, mental, and functional health and leisure activities. Finally, being a woman with complete dedication to domestic work is associated with a worse state of self-perceived health.

To evaluate early auditory performance, speech perception and language skills in Mandarin-speaking prelingual deaf children in the first two years after they received a cochlear implant (CI) and analyse the effects of possible associated factors. The Infant-Toddler Meaningful Auditory Integration Scale (ITMAIS)/Meaningful Auditory Integration Scale (MAIS), Mandarin Early Speech Perception (MESP) test and Putonghua Communicative Development Inventory (PCDI) were used to assess auditory and language outcomes in 132 Mandarin-speaking children pre- and post-implantation. Children with CIs exhibited an ITMAIS/MAIS and PCDI developmental trajectory similar to that of children with normal hearing. The increased number of participants who achieved MESP categories 1-6 at each test interval showed a significant improvement in speech perception by paediatric CI recipients. Age at implantation and socioeconomic status were consistently associated with both auditory and language outcomes in the first two years post-implantation. Mandarin-speaking children with CIs exhibit significant improvements in early auditory and language development. Though these improvements followed the normative developmental trajectories, they still exhibited a gap compared with normative values. Earlier implantation and higher socioeconomic status are consistent predictors of greater auditory and language skills in the early stage. Copyright © 2018 Elsevier B.V. All rights reserved.

IMPORTANCE Although many patients with end-stage cancer are offered chemotherapy to improve quality of life (QOL), the association between chemotherapy and QOL amid progressive metastatic disease has not been well-studied. American Society for Clinical Oncology guidelines recommend palliative chemotherapy only for solid tumor patients with good performance status. OBJECTIVE To evaluate the association between chemotherapy use and QOL near death (QOD) as a function of patients’ performance status. DESIGN, SETTING, AND PARTICIPANTS A multi-institutional, longitudinal cohort study of patients with end-stage cancer recruited between September 2002 and February 2008. Chemotherapy use (n = 158 [50.6%]) and Eastern Cooperative Oncology Group (ECOG) performance status were assessed at baseline (median = 3.8 months before death) and patients with progressive metastatic cancer (N = 312) following at least 1 chemotherapy regimen were followed prospectively until death at 6 outpatient oncology clinics in the United States. MAIN OUTCOMES AND MEASURES Patient QOD was determined using validated caregiver ratings of patients’ physical and mental distress in their final week. RESULTS Chemotherapy use was not associated with patient survival controlling for clinical setting and patients’ performance status. Among patients with good (ECOG score = 1) baseline performance status, chemotherapy use compared with nonuse was associated with worse QOD (odds ratio [OR], 0.35; 95% CI, 0.17-0.75; P = .01). Baseline chemotherapy use was not associated with QOD among patients with moderate (ECOG score = 2) baseline performance status (OR, 1.06; 95% CI, 0.51-2.21; P = .87) or poor (ECOG score = 3) baseline performance status (OR, 1.34; 95% CI, 0.46-3.89; P = .59). CONCLUSIONS AND RELEVANCE Although palliative chemotherapy is used to improve QOL for patients with end-stage cancer, its use did not improve QOD for patients with moderate or poor performance status and worsened QOD for patients with good performance status. The QOD in patients with end-stage cancer is not improved, and can be harmed, by chemotherapy use near death, even in patients with good performance status. PMID:26203912

It has been recognized that patients with non-small cell lung cancer who are lifelong never-smokers constitute a distinct clinical entity. The aim of this study was to assess clinical risk factors for survival among never-smokers with non-small cell lung cancer. All consecutive non-small cell lung cancer patients diagnosed (n = 285) between May 2005 and May 2009 were included. The clinical characteristics of never-smokers and ever-smokers (former and current) were compared using chi-squared or Student's t tests. Survival curves were calculated using the Kaplan-Meier method, and log-rank tests were used for survival comparisons. A Cox proportional hazards regression analysis was evaluated by adjusting for age (continuous variable), gender (female vs. male), smoking status (never- vs. ever-smoker), the Karnofsky Performance Status Scale (continuous variable), histological type (adenocarcinoma vs. non-adenocarcinoma), AJCC staging (early vs. advanced staging), and treatment (chemotherapy and/or radiotherapy vs. the best treatment support). Of the 285 non-small cell lung cancer patients, 56 patients were never-smokers. Univariate analyses indicated that the never-smoker patients were more likely to be female (68% vs. 32%) and have adenocarcinoma (70% vs. 51%). Overall median survival was 15.7 months (95% CI: 13.2 to 18.2). The never-smoker patients had a better survival rate than their counterpart, the ever-smokers. Never-smoker status, higher Karnofsky Performance Status, early staging, and treatment were independent and favorable prognostic factors for survival after adjusting for age, gender, and adenocarcinoma in multivariate analysis. Epidemiological differences exist between never- and ever-smokers with lung cancer. Overall survival among never-smokers was found to be higher and independent of gender and histological type.

We characterized health-related quality of life (HRQoL), cognitive, and functional status in newly diagnosed glioblastoma (GBM) patients receiving Tumor treating fields (TTFields) with temozolomide (TMZ) versus TMZ alone in a planned interim analysis of a randomized phase III trial [NCT00916409], which showed significant improvement in progression-free and overall survival with TTFields/TMZ. After radiotherapy with concomitant TMZ, newly diagnosed GBM patients were randomized (2:1) to TTFields/TMZ (n = 210) or TMZ (n = 105). Interim analysis was performed in 315 patients with ≥18 months of follow-up. HRQoL, a secondary endpoint, was evaluated in per-protocol patient population and expressed as change from baseline (CFB) at 3, 6, and 9 months for each subscale in the EORTC QLQ-C30/BN20. Karnofsky performance scores (KPS) and Mini-Mental State Examination scores (MMSE) were assessed. CFB in HRQoL was balanced in treatment groups at the 12-month time point. Initially, HRQoL improved in patients treated with TTFields/TMZ (CFB3: 24% and CFB6: 13%) versus TMZ (CFB3: -7% and CFB6: -17%), though this difference was no longer evident at the 9-month point. General scales, including physical and social functioning, showed no difference at 9 and 12 months. TTFields/TMZ group reported higher concerns of "itchy skin". KPS over 12 months was just below 90 in both groups. Cognitive status (MMSE) was stable over time. HRQoL, KPS, and MMSE were balanced in both groups over time. There was no preliminary evidence that HRQoL, cognitive, and functional status is adversely affected by the continuous use of TTFields.

Chemoradiotherapy for treatment of advanced head and neck cancer (HNC) is used to achieve organ preservation without compromising survival. Because chemoradiotherapy usually impacts adversely on nutritional and functional status, feeding by percutaneous endoscopic gastrostomy (PEG) is often part of the management regimen for these patients, but the presence of a PEG tube can also be associated with reduced quality of life (QOL). This study aimed to examine the factors associated with PEG insertion and the effects of PEG use on QOL and functional outcomes in HNC patients receiving chemoradiotherapy. Survey of 36 consecutive patients treated by primary chemoradiotherapy for HNC. Patient weight, age, tumour type, details of PEG insertion, feeding regimens and treatment were noted. The survey comprised the Performance Status Scale, the Functional Measure for Swallowing, Nutritional Mode and a self-assessment of QOL. PEG insertion within 1 month of treatment was associated with smaller fall in body mass index at 12 months than PEG insertion 1 month or more after the start of the treatment (P < 0.05). Body mass index change was inversely correlated with health-related quality of life and significantly related to lower speech and swallowing function scores. Longer PEG duration correlated with poorer performance status and swallowing function (P < 0.01). Longer PEG duration also predicted poorer overall QOL (P < 0.01) and poorer swallowing (P < 0.01) and speech (P < 0.05). Nutritional mode was related to overall QOL (P < 0.01). Nutritional support for HNC patients undergoing chemoradiotherapy is an essential component of patient care. Early PEG insertion and shorter PEG duration are associated with more favourable QOL-related outcomes.

Optimizing agent-based transmission models for infectious diseases.

Infectious disease modeling and computational power have evolved such that large-scale agent-based models (ABMs) have become feasible. However, the increasing hardware complexity requires adapted software designs to achieve the full potential of current high-performance workstations. We have found large performance differences with a discrete-time ABM for close-contact disease transmission due to data locality. Sorting the population according to the social contact clusters reduced simulation time by a factor of two. Data locality and model performance can also be improved by storing person attributes separately instead of using person objects. Next, decreasing the number of operations by sorting people by health status before processing disease transmission has also a large impact on model performance. Depending of the clinical attack rate, target population and computer hardware, the introduction of the sort phase decreased the run time from 26% up to more than 70%. We have investigated the application of parallel programming techniques and found that the speedup is significant but it drops quickly with the number of cores. We observed that the effect of scheduling and workload chunk size is model specific and can make a large difference. Investment in performance optimization of ABM simulator code can lead to significant run time reductions. The key steps are straightforward: the data structure for the population and sorting people on health status before effecting disease propagation. We believe these conclusions to be valid for a wide range of infectious disease ABMs. We recommend that future studies evaluate the impact of data management, algorithmic procedures and parallelization on model performance.

The Therapeutic Hypothermia After Pediatric Cardiac Arrest trials will determine whether therapeutic hypothermia improves survival with good neurobehavioral outcome, as assessed by the Vineland Adaptive Behavior Scales Second Edition, in children resuscitated after cardiac arrest in the in-hospital and out-of-hospital settings. We describe the innovative efficacy outcome selection process during Therapeutic Hypothermia After Pediatric Cardiac Arrest protocol development. Consensus assessment of potential outcomes and evaluation timepoints. None. We evaluated practical and technical advantages of several follow-up timepoints and continuous/categorical outcome variants. Simulations estimated power assuming varying hypothermia benefit on mortality and on neurobehavioral function among survivors. Twelve months after arrest was selected as the optimal assessment timepoint for pragmatic and clinical reasons. Change in Vineland Adaptive Behavior Scales Second Edition from prearrest level, measured as quasicontinuous with death and vegetative status being worst-possible levels, yielded optimal statistical power. However, clinicians preferred simpler multicategorical or binary outcomes because of easier interpretability and favored outcomes based solely on postarrest status because of concerns about accurate parental assessment of prearrest status and differing clinical impact of a given Vineland Adaptive Behavior Scales Second Edition change depending on prearrest status. Simulations found only modest power loss from categorizing or dichotomizing quasicontinuous outcomes because of high expected mortality. The primary outcome selected was survival with 12-month Vineland Adaptive Behavior Scales Second Edition no less than two SD below a reference population mean (70 points), necessarily evaluated only among children with prearrest Vineland Adaptive Behavior Scales Second Edition greater than or equal to 70. Two secondary efficacy outcomes, 12-month survival and quasicontinuous Vineland Adaptive Behavior Scales Second Edition change from prearrest level, will be evaluated among all randomized children, including those with compromised function prearrest. Extensive discussion of optimal efficacy assessment timing, and of the advantages versus drawbacks of incorporating prearrest status and using quasicontinuous versus simpler outcomes, was highly beneficial to the final Therapeutic Hypothermia After Pediatric Cardiac Arrest design. A relatively simple, binary primary outcome evaluated at 12 months was selected, with two secondary outcomes that address the potential disadvantages of primary outcome.

Chronic subdural hematoma (CSDH) can have a negative impact on autonomy of the elderly. Ambulatory and functional status may remain limited despite successful surgical evacuation. To evaluate the outcome of a postoperative assisted rehabilitation program. Single-institution short-term observational study. Inpatient (Neurosurgery Unit of a University Hospital). Thirty-five patients, aged 65 or older, who underwent burr-hole drainage for chronic subdural hematoma. Postoperatively all participants underwent a rehabilitation program, described in details, aimed at recovering standing position and gait as soon as possible. The program involved daily 30-minute individual sessions assisted by a physiotherapist, until discharge from hospital. The Markwalder's Grading Scale was used to assess the neurological status preoperatively and at discharge. The Trunk Control Test, the Standing Balance by Bohannon Scale and the Modified Rankin Scale were used to evaluate balance and general function (primary outcome) in the immediate postoperative and at discharge. We also recorded the rate of pre-CSDH walking patients who maintained ambulation at discharge and the discharge destination (secondary outcome). Total scores of Markwalder's Grading Scale, Trunk Control Test, Standing Balance by Bohannon Scale and Modified Rankin Scale improved (P<0.05), indicating a global favorable outcome, especially for balance. Excluding the patients who were dependent pre-CSDH, the others maintained gait function in 74.2% of cases. Only 45.7% of the patients were discharged home, the others being divided between inpatient medical settings and rehabilitation. The rehabilitation program was well tolerated by the patients. Our study showed a clear improvement in trunk control and standing balance and an overall favorable outcome for neurological and ambulatory status at discharge. Despite an assisted postoperative rehabilitation program, the residual impairment in general function was the main factor that prevents us to discharge more elderly patients home rather than to assisted settings. The results of this descriptive study suggest that an assisted rehabilitation program may be helpful in improving short-term postoperative balance and ambulatory status (more than functional status), but further studies, with a randomized controlled design, are certainly justified to understand the efficacy of rehabilitation in this context.

This study aimed to explore the levels of John Henryism (JH) active coping and its association with acculturation status and psychological health (specifically perceived stress, acculturative stress, anxiety, and depression) in Korean immigrants to the United States. In 102 Korean immigrants, JH active coping was measured by the JH Scale; acculturation by the Bidimensional Acculturation Scale; perceived stress by the Perceived Stress Scale; acculturative stress by the Social, Attitudinal, Familial, and Environmental Scale; anxiety by the State Anxiety Subscale of the Spielberger State-Trait Anxiety Inventory; and depression by the Center for Epidemiological Studies Depression Scale. The levels of JH active coping in this sample of Korean immigrants appear to be lower than the levels reported in other racial groups. Independent of demographic factors, JH active coping was a significant predictor of higher acculturation status and better psychological health as indicated by lower levels of perceived stress, acculturative stress, anxiety, and depressive symptoms.

Objective To develop a reliable rating scale to assess functional capacity in children with familial dysautonomia, evaluate changes over time and determine whether severity within a particular functional category at a young age affected survival. Study design Ten functional categories were retrospectively assessed in 123 patients with familial dysautonomia at age 7 years ± 6 months. Each of the ten Functional Severity Scale (FuSS) categories (motor development, cognitive ability, psychological status, expressive speech, balance, oral coordination, frequency of dysautonomic crisis, respiratory, cardiovascular and nutritional status) was scored from 1 (worst or severely affected) to 5 (best or no impairment). Changes over time were analyzed further in 22 of the 123 patients who were also available at ages 17 and 27 years. Results Severely impaired cardiovascular function and high frequency of dysautonomic crisis negatively affected survival (p<0.005 and p<0.001, respectively). In the 22 individuals followed up to age 27 years, psychological status significantly worsened (p=0.01), and expressive speech improved (p=0.045). From age 17 to 27 years, balance worsened markedly (p =0.048). Conclusion The FuSS scale is a reliable tool to measure functional capacity in patients with familial dysautonomia. The scale may prove useful in providing prognosis and as a complementary endpoint in clinical trials. PMID:22727867

Discrepancies between physicians' assessment and patients' subjective representations of the disease severity may influence physician-patient communication and management of a chronic illness, such as multiple sclerosis (MS). For these reasons, it is important to recognize factors that distinguish patients who differently estimate the impact of MS. The purpose of this study was to verify if the patients who overestimate or underestimate the impact of MS differ in their perception of personal resources from individuals presenting with a realistic appraisal of their physical condition. A total of 172 women and 92 men diagnosed with MS completed Multiple Sclerosis Impact Scale, University of Washington Self Efficacy Scale, Rosenberg Self-Esteem Scale, Body Esteem Scale, Brief Illness Perception Questionnaire, Treatment Beliefs Scale, Actually Received Support Scale, and Socioeconomic resources scale. Physician's assessment of health status was determined with Expanded Disability Status Scale. Linear regression analysis was conducted to identify the subsets of patients with various patterns of subjective health and Expanded Disability Status Scale (EDSS) scores. Patients overestimating the impact of their disease presented with significantly lower levels of self-esteem, self-efficacy in MS, and body esteem; furthermore, they perceived their condition more threatening than did realists and underestimators. They also assessed anti-MS treatment worse, had less socioeconomic resources, and received less support than underestimators. Additionally, underestimators presented with significantly better perception of their disease, self, and body than did realists. Self-assessment of MS-related symptoms is associated with specific perception of personal resources in coping with the disease. These findings may facilitate communication with patients and point to new directions for future research on adaptation to MS.

Self-transcendence and well-being in homeless adults.

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

Trickle-Down Preferences: Preferential Conformity to High Status Peers in Fashion Choices

How much do our choices represent stable inner preferences versus social conformity? We examine conformity and consistency in sartorial choices surrounding a common life event of new norm exposure: relocation. A large-scale dataset of individual purchases of women’s shoes (16,236 transactions) across five years and 2,007 women reveals a balance of conformity and consistency, moderated by changes in location socioeconomic status. Women conform to new local norms (i.e., average heel size) when moving to relatively higher status locations, but mostly ignore new local norms when moving to relatively lower status locations. In short, at periods of transition, it is the fashion norms of the rich that trickle down to consumers. These analyses provide the first naturalistic large-scale demonstration of the tension between psychological conformity and consistency, with real decisions in a highly visible context.

Increasing evidence underscores the health benefits of Tai Chi (TC), although there is limited evidence of benefits among racial and ethnic minorities. This study investigated the impact of psychosocial status on balance among 23 Latino seniors after a twice-a-week, 12-week TC exercise program. Functional status was measured at baseline, immediately after, and three months following the TC exercise program, using the Timed Up and Go Test and Tinetti Falls Efficacy Scale. Psychosocial status was measured at baseline by the Center for Epidemiologic Studies Depression Scale and Norbeck Social Support Questionnaire. Both measures of functional status improved and were sustained after three months of TC. Greater improvement was significantly related to a higher level of baseline social support. More depressed seniors reported less fear of falling after TC. Depression and social support are important moderators of functional improvement after TC among Latino seniors.

Objective To identify which physician and patient characteristics are associated with physicians' estimation of their patient social status. Design Cross-sectional multicentric survey. Setting Fourty-seven primary care private offices in Western Switzerland. Participants Random sample of 2030 patients ≥16, who encountered a general practitioner (GP) between September 2010 and February 2011. Main measures Primary outcome: patient social status perceived by GPs, using the MacArthur Scale of Subjective Social Status, ranging from the bottom (0) to the top (10) of the social scale.Secondary outcome: Difference between GP's evaluation and patient's own evaluation of their social status. Potential patient correlates: material and social deprivation using the DiPCare-Q, health status using the EQ-5D, sources of income, and level of education. GP characteristics: opinion regarding patients' deprivation and its influence on health and care. Results To evaluate patient social status, GPs considered the material, social, and health aspects of deprivation, along with education level, and amount and type of income. GPs declaring a frequent reflexive consideration of their own prejudice towards deprived patients, gave a higher estimation of patients' social status (+1.0, p = 0.002). Choosing a less costly treatment for deprived patients was associated with a lower estimation (−0.7, p = 0.002). GP's evaluation of patient social status was 0.5 point higher than the patient's own estimate (p<0.0001). Conclusions GPs can perceive the various dimensions of patient social status, although heterogeneously, according partly to their own characteristics. Compared to patients' own evaluation, GPs overestimate patient social status. PMID:24454752

Objectives Feline osteoarthritis causes pain and disability. Detection and measurement is challenging, relying heavily on owner report. This study describes refinement of the Montreal Instrument for Cat Arthritis Testing, for Use by Veterinarians. Methods A video analysis of osteoarthritic (n = 6) and non-osteoarthritic (n = 4) cats facilitated expansion of scale items. Three successive therapeutic trials (using gabapentin, tramadol and oral transmucosal meloxicam spray) in laboratory cats with and without natural osteoarthritis (n = 12-20), permitted construct validation (assessments of disease status sensitivity and therapeutic responsiveness) and further scale refinements based on performance. Results Scale osteoarthritic sensitivity improved from phase I to phase III; phase III scale total score ( P = 0.0001) and 4/5 subcategories - body posture ( P = 0.0006), gait ( P = 0.0031), jumping (0.0824) and global distance examination ( P = 0.0001) - detected osteoarthritic cats. Total score inter-rater (intra-class correlation coefficients [ICC] = 0.64-0.75), intra-rater (ICC = 0.90-0.91) and overall internal consistency (Cronbach's alpha = 0.85) reliability were good to excellent. von Frey anesthesiometer-induced paw withdrawal threshold increased with gabapentin in phase I, in osteoarthritic cats ( P <0.001) but not in non-osteoarthritic cats ( P = 0.075). Night-time activity increased during gabapentin treatment. Objective measures also detected tramadol and/or meloxicam treatment effects in osteoarthritic cats in phases II and III. There was some treatment responsiveness: in phase I, 3/10 subcategory scores improved ( P <0.09) in treated osteoarthritic cats; in phase II, 3/8 subcategories; and in phase III, 1/5 subcategories improved ( P <0.096). Conclusions and relevance The revised scale detected naturally occurring osteoarthritis, but not treatment effects, in laboratory cats, suggesting future potential for screening of at-risk cats. Further study is needed to confirm reliability, validity (disease sensitivity and treatment responsiveness) and clinical feasibility, as well as cut-off scores for osteoarthritic vs non-osteoarthritic status, in client-owned cats.

Although aging is one of the most important risk factors for cancer, elderly patients tend to be excluded from cancer clinical trials, only on the basis of chronologic age. Performance Status (PS) has been used widely to select adult patients for entry into clinical trials, but it does not include a comprehensive evaluation of various age-related factors in the elderly. This study was designed to assess the reliability and validity of a multidimensional geriatric assessment protocol for elderly patients with cancer. Thirty consecutive elderly patients (> or = 65 years), diagnosed with hematologic neoplasia or solid tumors and undergoing chemotherapy or radiotherapy, were given a specifically structured multidimensional questionnaire (MACE) three times during one week by two different physicians. MACE was intended to collect information on demographics, socioeconomic status, cognitive status, depression, physical performance, disability, and tumor characteristics. In parallel with MACE, information was collected by means of the Sickness Impact Profile (SIP). Both for inter-rater and test-retest reliability, the values of the intraclass correlation coefficient (ICC) were generally higher than 0.7. Disability, cognitive status, depressive symptoms, and the number of days spent in bed sick in the last two weeks were markedly correlated with the global, physical, and social SIP score. Disability alone explained 70% of the variance in the SIP global score, 83% of the variance in the SIP physical score, and 45% of the variance in the SIP psychosocial score. MACE proved to be applicable in a reasonable amount of time (around 30 minutes) for a medical oncology ward. These data indicate that this structured evaluation of functional status is feasible and reliable. MACE is therefore proposed as a clinical research tool to avoid arbitrary decisions on patient selection for enrollment in clinical trials, to favor uniform monitoring of treatment, and to allow a better comparison of results.

The Behavioral Pain Scale (BPS) is a tool of pain assessment that often gives contradictory results when used by different raters. To assess internal consistency and interrater reliability of BPS scale in the pain assessment performed by intensives care nurses. A prospective observational study in 34 mechanically-ventilated patients, carried out in an Intensive Care Unit from April to June 2012. Variables analyzed included demographic characteristics, diagnosis of referral, clinical status, pain and sedation level. Pain was assessed by two nurses independently at rest (T1) and during a mobilization procedure (T2) using the BPS scale. Internal consistency was calculated by Cronbach's alpha, and intraobserver reliability was determined with the intraclass correlation coefficient (ICC), with a confidence interval (CI) of 95%. This study was approved by the Ethical Committee for Clinical Research. One-hundred and twenty-eight pain assessments were performed. The Cronbach's alpha of total BPS score at rest was 0.66 (95%CI: 0.33 to 0.83) and during mobilization of 0.73 (95%CI: 0.47 to 0.87). The CCI of total BPS score was 0.50 (95%CI: 0.19 to 0.71) at rest and 0.58 (95%CI: 0.31 to 0.77) during mobilization. The level of internal consistency of the scale is appropriate and moderate interrater agreement. For the BPS useful in clinical practice, it is imperative that nurses have prior experience with a regulated use of this tool. Copyright © 2014 Elsevier España, S.L.U. y SEEIUC. All rights reserved.

The effects of individual status and group performance on network ties among teammates in the National Basketball Association

Aven, Brandy

2018-01-01

For individuals, status is derived both from their personal attributes and the groups with whom they are affiliated. Depending on the performance of their groups, the status of individuals may benefit or suffer from identifying closely with the group. When the group excels, high-status members potentially receive much of the credit and increased status. Conversely, high-status members of underperforming groups potentially suffer disproportionate declines in their status relative to the low-status group members. We therefore predict an interaction between group performance and individual status on the willingness to associate with the group and its members. We test our prediction by examining social media ties among teammates in the National Basketball Association. Specifically, we investigate the “following” ties of teammates on Twitter at the end of the 2014–2015 season. Elections to All-Star games are used to measure the status of players, and team performance is measured by recent success in the postseason playoffs. The results show that compared to high-status players on successful teams, high-status players on underperforming teams are less likely to follow their teammates. This result aligns with research on status inconsistency, suggesting that individuals deemphasize their group affiliation when it jeopardizes their individual status. An additional contribution is the advancement of the probit Social Relations Model for the analysis of binary ties in social networks. PMID:29708984

Fibromyalgia (FM) is a form of non-articular rheumatism characterised by chronic widespread musculoskeletal aching. Although some works have investigated the possible role of oxidative stress in the pathophysiology of FM, none has analysed a significant number of oxidative markers in the same patients. Consequently, we have performed an exhaustive study of the oxidative/antioxidative status in FM patients and healthy controls, as well as the relationship with FM clinical parameters. In 45 female patients and 25 age-matched controls, we investigated the oxidative (lipid and protein peroxidation, and oxidative DNA damage) and antioxidative status (total antioxidant capacity (TAC), and antioxidant enzyme activities and compounds). Functional capacity and musculoskeletal pain were assessed by Fibromyalgia Impact Questionnaire (FIQ) and Visual Analogue Scale (VAS), respectively. The physical (PCS-12) and mental (MCS-12) health status was evaluated by SF-12. A significant increase in oxidative DNA damage and protein carbonyl content was found in FM patients vs. controls, as well as in antioxidant compounds such as copper and ceruloplasmin. Patients had diminished levels of TAC and zinc. Enzyme activities of superoxide dismutase, glutathione peroxidase, and catalase were lower in FM patients. Significant correlations were observed in patients between oxidative DNA damage and MCS-12, and zinc and PCS-12. These findings reveal an imbalance between oxidants and antioxidants in FM patients. The lower antioxidant enzyme activities may lead to oxidative stress through the oxidation of DNA and proteins, which may affect the health status of FM patients.

To examine symptoms, physical function, and nutritional status in patients with fibromyalgia (FM) after 6 to 8 years. Of 51 women with FM initially included in exercise and patient education programs 6 and 8 years ago, 33 agreed to participate. Median (range) age was 45.5 years (33-64) and symptom duration 18 years (8-46). Symptoms (visual analog scales), cardiovascular capacity (Aastrand's test), and restriction on daily activities (Fibromyalgia Impact Questionnaire) were measured. Employment status and experience of coping with everyday life were addressed in an interview. Nutritional status was evaluated by anthropometric measurements and dietary intake. All the 33 participants had widespread chronic pain, and 79% had enough tender points to satisfy the FM classification criteria. Compared with initital data there were significant reductions in the number of tender points (p = 0.004) in the exercise group, and in fatigue (p = 0.008) and pain (p = 0.5) in the patient education group. Cardiovascular capacity was within normal limits in 33% of the participants. Currently, 26 performed regular physical activity and of these, 10 were engaged in organized exercise. Seventy-two percent reported regular use of dietary supplements and attached importance to a healthy diet. Still, there was a significant increase in weight and body fat, and 24% were obese (BMI > 30). The coping strategies adopted were adjustments to the new situation and distraction from symptoms. No worsening of symptoms and no change in employment status, as well as frequent participation in physical activities, suggests a benign longterm outcome in these patients with FM.

This study reports on a large cross-sectional study of violence against women in Turkey, and outlines the risk factors associated with intimate partner violence. The purpose of this study was to identify in order to evaluate the domestic violence against women living in Manisa and to determine the risk factors affecting this situation. We implemented a cross-sectional descriptive study in the Manisa province of Turkey. The research data were collected by using a "Women's Information Form" consisting of 32 items, and "Scale of Domestic Violence Against Women". The study was conducted with 1760 women who complied with the inclusion criteria. It was determined that score averages of 30.0% of women from the scale of domestic violence against women were above the score average of the scale (71.38 ± 10.71) and they were exposed to violence more than the others. A statistically significant difference was obtained in the statistical analysis made between score averages from the scale of domestic violence against women and such variables as age, education, employment status, social insurance, immigration status, place of residence, marital age, year of marriage of women; age, education status, employment status of husband; and whether the husband has another wife (p < 0.05). It was also found out that the rate of domestic violence against women is high, women does not perceive many behaviors of their husbands as violence, and the most important factor leading to this situation is social status. It is believed that the results of the study will be a guidance to local authorities, formal and voluntary organizations, educational institutions, and relevant researchers in the prevention of violence against women.

This paper reports a study to examine change in psychosocial status following a 12-week Tai Chi exercise intervention among ethnic Chinese people with cardiovascular disease risk factors living in the United States of America. Regular participation in physical activity is associated with protection against cardioavascular disease, and improvements in physical and psychological health. Increasing amounts of scientific evidence suggests that mind-body exercise, such as Tai Chi, are related to improvements in mental health, emotional well-being, and stress reduction. No prior study has examined the effect of a Tai Chi exercise intervention on psychosocial status among people with cardiovascular disease risk factors. This was a quasi-experimental study. Participants attended a 60-minute Tai Chi exercise class three times per week for 12 weeks. Data were collected at baseline, 6 and 12 weeks following the intervention. Psychosocial status was assessed using Chinese versions of Cohen's Perceived Stress Scale, Profile of Mood States, Multidimensional Scale of Perceived Social Support, and Tai Chi exercise self-efficacy. A total of 39 participants, on average 66-year-old (+/-8.3), married (85%), Cantonese-speaking (97%), immigrants participated. The majority were women (69%), with < or =12 years education (87%). Statistically significant improvements in all measures of psychosocial status were found (P < or = 0.05) following the intervention. Improvement in mood state (eta2 = 0.12), and reduction in perceived stress (eta2 = 0.13) were found. In addition, Tai Chi exercise statistically significantly increased self-efficacy to overcome barriers to Tai Chi (eta2 = 0.19), confidence to perform Tai Chi (eta2 = 0.27), and perceived social support (eta2 = 0.12). Tai Chi was a culturally appropriate mind-body exercise for these older adults, with statistically significant psychosocial benefits observed over 12-weeks. Further research examining Tai Chi exercise using a randomized clinical trial design with an attention-control group may reduce potential confounding effects, while exploring potential mechanisms underlying the relaxation response associated with mind-body exercise. In addition, future studies with people with other chronic illnesses in all ethnic groups are recommended to determine if similar benefits can be achieved.

Chronic graft-versus-host disease occurs in 20-50% of allogeneic hematopoietic cell transplantation survivors. We surveyed patients about their quality of life, symptoms, health status, comorbid conditions and medication. Instruments included the Short-Form-36 (SF-36), the Patient-Reported Outcomes Measurement Information System (PROMIS) Global and PROMIS-29 scales and the Lee Chronic Graft-versus-Host Disease Symptom Scale. Functional status was measured by self-reported Karnofsky and work status. Of 3027 surveys sent to recipients surviving one or more years after transplantation, 1377 (45%) were returned. Among these, patients reported their chronic graft-versus-host disease was mild (n=257, 18.7%), moderate (n=110, 8.0%) or severe (n=25, 1.8%). Another 377 (27.4%) never had chronic graft-versus-host disease and 280 (20.3%) had chronic graft-versus-host disease but it resolved. We excluded 328 (23.8%) who did not answer the questions about chronic graft-versus-host disease. Patients who reported moderate or severe chronic graft-versus-host disease reported worse quality of life, lower performance status, a higher symptom burden and were more likely to be taking prescription medications for pain, anxiety and depression compared to those with resolved chronic graft-versus-host disease. Self-reported measures were similar between patients with resolved chronic graft-versus-host disease and those who never had it. Our data suggest that the PROMIS measures may be able to replace the SF-36 in chronic graft-versus-host disease assessment. Between 26.7-39.4% of people with active chronic graft-versus-host disease were unable to work due to health reasons, compared with 12.1% whose chronic graft-versus-host disease had resolved and 15.4% who never had chronic graft-versus-host disease. Mouth, eye and nutrition symptoms persisted after resolution of chronic graft-versus-host disease. These results show that better prevention of and treatment for chronic graft-versus-host disease is needed to improve survivorship after allogeneic transplantation.

The aim of this study was to examine the relationship of psychosocial factors, namely, pain catastrophizing, kinesiophobia, and maladaptive coping strategies, with muscle strength, pain, and physical performance in patients with knee osteoarthritis (OA)-related symptoms. A total of 109 women (64 with knee OA-related symptoms) with a mean age of 65.4 years (49-81 years) were recruited for this study. Psychosocial factors were quantified by the Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, and Pain Coping Inventory. Clinical features were assessed using isometric and isokinetic knee muscle strength measurements, visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index, and functional tests. Associations were examined using correlation and regression analysis. In knee OA patients, pain catastrophizing, kinesiophobia, and coping strategy explained a significant proportion of the variability in isometric knee extension and flexion strength (6.3%-9.2%), accounting for more overall variability than some demographic and medical status variables combined. Psychosocial factors were not significant independent predictors of isokinetic strength, knee pain, or physical performance. In understanding clinical features related to knee OA, such as muscle weakness, pain catastrophizing, kinesiophobia, and coping strategy might offer something additional beyond what might be explained by traditional factors, underscoring the importance of a biopsychosocial approach in knee OA management. Further research on individual patient characteristics that mediate the effects of psychosocial factors is, however, required in order to create opportunities for more targeted, personalized treatment for knee OA.

This study aimed to examine the association between the length of use of feeding bottles or pacifiers during childhood and the prevalence of respiratory and allergic morbidities. A large-scale questionnaire survey was performed in day care centers and kindergartens (with children's ages ranging from 2 to 7 years) in southern Taiwan, and a total of 14,862 questionnaires completed by parents were finally recruited for data analysis. Effects of using feeding bottles on children's wheezing/asthma (adjusted OR: 1.05, 95% CI 1.00-1.09), allergic rhinitis (adjusted OR: 1.04, 95% CI 1.00-1.08), and eczema (adjusted OR: 1.07, 95% CI 1.01-1.2) were found. Moreover, significant dose-dependent relationships were further established after an adjustment for confounders was performed that included children's ages, gender, gestational age, birth weight, length of breastfeeding, the age when first given infant formula or complementary foods, family history, parental educational levels, and smoking status, as well as the problem of indoor water damage. This study was the first to reveal the potential risk of using plastic consumer products such as feeding bottles on the reported health status of preschool children in Asian countries.

The prevalence of social anxiety disorder (SAD) is frequently higher in younger age groups and people with other anxiety or mood disorders; however, it is unclear whether these groups have a higher risk for developing SAD or are simply more likely to endorse diagnostic criteria than other people with similar levels of social anxiety. Explicitly testing the assumption all people respond to structured diagnostic interviews in comparable ways (measurement invariance) is essential in ensuring systematic response biases do not create spurious group differences. This research aims to systematically test whether age, comorbidity status, or types of social fears affect responses to a structured diagnostic interview. Responses from 1755 participants in a large-scale survey of mental health in Australia screening into the social phobia/SAD section of the Composite International Diagnostic Interview were used. Three series of multigroup confirmatory factor analyses for categorical data systematically tested for increasingly strict levels of measurement invariance. Overall, patterns of responding to diagnostic criteria were comparable across the groups, supporting assumptions of measurement invariance. Establishment of invariance supports the interpretation of differences between age, comorbidity status, and types of social situations feared as genuine differences in experience as opposed to measurement biases.

Terrestrial photovoltaic modules must undergo substantial reductions in cost in order to become economically attractive as practical devices for large scale production of electricity. Part of the cost reductions must be realized by the encapsulation materials that are used to package, protect, and support the solar cells, electrical interconnects, and other ancillary components. As many of the encapsulation materials are polymeric, cost reductions necessitate the use of low cost polymers. The performance and status of ethylene vinyl acetate, a low cost polymer that is being investigated as an encapsulation material for terrestrial photovoltaic modules, are described.

This study compared the accuracy of intraoral film and a charge-coupled device (CCD) receptor for proximal caries detection. Four observers evaluated images of the proximal surfaces of 40 extracted posterior teeth. The presence or absence of caries was scored using a five-point confidence scale. The actual status of each surface was determined from ground section histology. Responses were evaluated by means of receiver operating characteristic (ROC) analysis. Areas under ROC curves (Az) were assessed through a paired t-test. The performance of the CCD-based intraoral sensor was not different statistically from Ektaspeed Plus film in detecting proximal caries.

The problems of relative deprivation: why some societies do better than others.

PubMed

Wilkinson, Richard G; Pickett, Kate E

2007-11-01

In this paper, we present evidence which suggests that key processes of social status differentiation, affecting health and numerous other social outcomes, take place at the societal level. Understanding them seems likely to involve analyses and comparisons of whole societies. Using income inequality as an indicator and determinant of the scale of socioeconomic stratification in a society, we show that many problems associated with relative deprivation are more prevalent in more unequal societies. We summarise previously published evidence suggesting that this may be true of morbidity and mortality, obesity, teenage birth rates, mental illness, homicide, low trust, low social capital, hostility, and racism. To these we add new analyses which suggest that this is also true of poor educational performance among school children, the proportion of the population imprisoned, drug overdose mortality and low social mobility. That ill health and a wide range of other social problems associated with social status within societies are also more common in more unequal societies, may imply that income inequality is central to the creation of the apparently deep-seated social problems associated with poverty, relative deprivation or low social status. We suggest that the degree of material inequality in a society may not only be central to the social forces involved in national patterns of social stratification, but also that many of the problems related to low social status may be amenable to changes in income distribution. If the prevalence of these problems varies so much from society to society according to differences in income distribution, it suggests that the familiar social gradients in health and other outcomes are unlikely to result from social mobility sorting people merely by prior characteristics. Instead, the picture suggests that their frequency in a population is affected by the scale of social stratification that differs substantially from one society to another.

Most elderly persons live in developing countries where current geriatric epidemiological data are scarce. We aimed to study major comorbidities, polypharmacy, functional and nutritional status in a Turkish community-dwelling female elderly clinic population. Female geriatrics outpatient clinic patients were assessed cross-sectionally. Patients underwent comprehensive geriatric cassessment, including identification of chronic diseases, drugs, functionality, and nutrition. Comorbidities and drugs were defined by the review of patients' self-reports and current medications. Geriatric depression and cognition were assessed by 30-item geriatric depression scale and Folstein mini-mental-state-examination. Functional status was assessed by the evaluation of activities of daily living (ADL) and instrumental activities of daily living (IADL) scales. Nutritional assessment was performed by mini-nutritional-assessment-short form. Five-hundred and fifteen patients were included in this study over an 8-year period. Mean age was 73.4 ± 6.9 years. Mean number of chronic diseases was 2.8. 61.1 % had >3 chronic diseases. Most common 3 diagnoses were hypertension (75.3 %), depression (45.5 %) and dementia (39.4 %). Mean number of drugs was 4.8. Polypharmacy was noted as 63.2 and 47.6 % by definitions as >4 or >5 chronic drug use, respectively. Subjects with at least one dependency of ADL and IADL were 23.4 and 64.0 %. Prevalence of poor nutrition was 39.1 %. In patients with at least one ADL or IADL dependency, undernutrition (p < 0.001), dementia (p < 0.001), cerebrovascular accident, Parkinson's disease, diabetes were more prevalent (p < 0.05) and were taking higher number of drugs (p < 0.01). Polypharmacy and functional dependency seem to be prevalent among female elders in our country. Nutritional status was worse than the other reported urban area of Turkey and also than among males of same region but better than among Iranian counterparts. This study illustrates geographical differences in and between the individual countries and supports the continued need for comprehensive geriatric assessment worldwide.

Both diabetes and hemodialysis can seriously impair patients' health related quality of life (HRQOL). This study seeks to obtain data which will help to address the factors associated with impaired HRQOL in hemodialysis patients with diabetes in Palestine. A cross-sectional study was performed in multiple centers in the period from November 2016 to June 2017. We utilized the Arabic version of EuroQoL 5 Dimensions 5 Levels (EQ-5D-5L) scale and EuroQol-visual analogue scale (EQ-VAS) to measure patients' HRQOL. The study was conducted in six dialysis centers in the North of West Bank, Palestine. Descriptive and comparative statistics were used to describe clinical and socio-demographic features of patients. Multiple linear regression analysis was used to determine the association between clinical and socio-demographic factors and HRQOL score. One hundred and forty one diabetic patients undergoing hemodialysis were enrolled in our study. Overall, 52.5% of them (74 patients) were males; the patients had a mean age of 60.32 with 52.5% of them aged below 60. The mean ± standard deviation of EQ-5D-5L index and EQ-VAS score was 0.314 ± 0.4 and 50.85±22.43, respectively. The findings of this study suggest that female patients, uneducated patients, unemployed patients, unmarried patients, and patients with more chronic diseases and comorbidities had a significant poor HRQOL scores (p values <0.05). Variables such as marital status and occupational status were significantly (p < 0.05) associated with the QOL score. More specifically, married status and employed patients positively associated with QOL score (β = 0.22; p = 0.016 and β = 0.27; p = 0.013, respectively). Among diabetic patients undergoing hemodialysis, married status and being employed were associated with modestly higher scores of QOL. We recommend that healthcare providers give more attention to diabetic dialysis patients who are unemployed and unmarried, as they are at a higher risk of having impaired HRQOL.

The accumulation of excess body weight may have important health and disease consequences for persons with multiple sclerosis (MS). This study examined the effect of weight status on mobility using a comprehensive set of mobility outcomes including ambulatory performance (timed 25-foot walk, T25FW; 6-minute walk, 6MW; oxygen cost of walking, Cw; spatiotemporal parameters of gait; self-reported walking impairment, Multiple Sclerosis Walking Scale-12 (MSWS-12); and free-living activity, accelerometry) in 168 ambulatory persons with MS. Mean (SD) BMI was 27.7 (5.1) kg/m2. Of the 168 participants, 31.0% were classified as normal weight (BMI = 18.5–24.9 kg/m2), 36.3% were classified as overweight (BMI = 25.0–29.9 kg/m2), and 32.7% were classified as obese, classes I and II (BMI = 30–39.9 kg/m2). There were no significant differences among BMI groups on T25FW and 6MW, Cw, spatiotemporal gait parameters, MSWS-12, or daily step and movement counts. The prevalence of overweight and obesity in this sample was almost 70%, but there was not a consistent nor significant impact of BMI on outcomes of mobility. The lack of an effect of weight status on mobility emphasizes the need to focus on and identify other factors which may be important targets of ambulatory performance in persons with MS.

This study was to identify the relationships of trait anger, mode of anger expression, and perceived stress to mental health status in middle aged women. The subjects were 157 middle aged women from 40s to 60s who lived in Seoul. Data was collected by questionnaire surveys using the convenience sampling. The instruments used for this study were Spielberger's trait anger scale and anger expression scale, Cohen, Kamarck, and Mermelstein's perceived stress and Derogatis's SCL-90-R. The collected data was analyzed using descriptive statistics, Pearson correlation coefficient, and Stepwise multiple regression with SAS/PC. The trait anger of middle aged women indicated a significantly positive correlation to perceived stress(r=.180, p=.023) and mental health status(r.=021, p=.014). Anger-in(r=.237, p<.05), and perceived stress(p=.461, p<.01) showed significantly positive correlation to mental health status. The most significant predictor influencing health status of middle aged women was perceived stress, and anger-in and the variance explained was 27%. These results suggested that middle aged women with high degree of trait anger is likely to be high in stress perception. Perceived stress and anger-in are major factors influencing mental health status.

In the United States, adults with Autism Spectrum Disorder (ASD) experience high rates of unemployment and underemployment in relation to adults with other disabilities and the general population. Yet there is little research examining their employment experiences and the predictors of employment status. The purpose of this study was to examine the employment characteristics and histories of both employed and unemployed adults with ASD, and the factors that contributed to their employment status. This cross-sectional study used an online survey and the Short Effort Reward Imbalance (ERI) Scale to gather data. Multivariate logistic regression analyses were used to examine predictors of employment status and self-reported health. Of the 254 adults with ASD who participated in this study, 61.42% were employed and 38.58% were unemployed. Over half of the participants reported job imbalance on the Short ERI Scale and the vast majority did not receive any job assistance. Participants who disclosed their ASD diagnosis to their employer were more than three times as likely to be employed than those who did not disclose. Education level was also a significant predictor of employment status. This study suggests disability disclosure and education level are factors that contribute to employment status.

This study investigated the sensitivity and specificity of a computer-automated telephone system to evaluate cognitive impairment in elderly callers to identify signs of early dementia. The Clinical Dementia Rating Scale was used to assess 155 subjects aged 56 to 93 years (n = 74, 27, 42, and 12, with a Clinical Dementia Rating Scale score of 0, 0.5, 1, and 2, respectively). These subjects performed a battery of tests administered by an interactive voice response system using standard Touch-Tone telephones. Seventy-four collateral informants also completed an interactive voice response version of the Symptoms of Dementia Screener. Sixteen cognitively impaired subjects were unable to complete the telephone call. Performances on 6 of 8 tasks were significantly influenced by Clinical Dementia Rating Scale status. The mean (SD) call length was 12 minutes 27 seconds (2 minutes 32 seconds). A subsample (n = 116) was analyzed using machine-learning methods, producing a scoring algorithm that combined performances across 4 tasks. Results indicated a potential sensitivity of 82.0% and specificity of 85.5%. The scoring model generalized to a validation subsample (n = 39), producing 85.0% sensitivity and 78.9% specificity. The kappa agreement between predicted and actual group membership was 0.64 (P<.001). Of the 16 subjects unable to complete the call, 11 provided sufficient information to permit us to classify them as impaired. Standard scoring of the interactive voice response-administered Symptoms of Dementia Screener (completed by informants) produced a screening sensitivity of 63.5% and 100% specificity. A lower criterion found a 90.4% sensitivity, without lowering specificity. Computer-automated telephone screening for early dementia using either informant or direct assessment is feasible. Such systems could provide wide-scale, cost-effective screening, education, and referral services to patients and caregivers.

Patients with cancer anorexia-cachexia syndrome (CACS) suffer a significant symptom burden, impaired quality of life (QoL), and shorter survival. Measurement of QoL impairments related to CACS is thereby important both in clinical practice and in research. We aimed to further validate the Functional Assessment of Anorexia-Cachexia Therapy (FAACT) scale in an advanced lung cancer population. We tested the performance of the FAACT and its anorexia-cachexia subscale (ACS) within a dataset of patients with advanced non-small cell lung cancer (aNSCLC), using standard statistical methods. We then compared the performance of commonly used QoL measures stratified by CACS status and by patient self-report of appetite and weight loss. The FAACT and its ACS demonstrate internal validity consistent with acceptable published ranges for other QoL scales (Cronbach alpha = 0.9 and 0.79, respectively). Correlation coefficients demonstrate moderate correlations in the expected directions between FAACT and ACS and scales that measure related constructs. Comparing patients with and without CACS, the ACS is more sensitive to change than other QoL instruments (mean score 33.1 vs. 37.2, p = 0.011, ES = 0.58). In patients with aNSCLC, the FAACT and its ACS performed well compared with other instruments, further supporting their validity and value in clinical research. FAACT and ACS scores covaried with symptoms and other QoL changes that are typical hallmarks of CACS, lending further support to their use as QoL endpoints in clinical trials among patients with CACS.

Mediterranean shrubs are an important component of both Mediterranean vegetation communities and understorey vegetation. They also constitute the surface fuels primarily responsible for the ignition and the spread of wildland fires in Mediterranean forests. Although fire spread and behaviour are dependent on several factors, the water content of live fuel plays an important role in determining fire occurrence and spread, especially in the Mediterranean shrubland, where live fuel is often the main component of the available fuel which catches fire. According to projections on future climate, an increase in risk of summer droughts is likely to take place in Southern Europe. More prolonged drought seasons induced by climatic changes are likely to influence general flammability characteristics of fuel, affecting load distribution in vegetation strata, floristic composition, and live and dead fuel ratio. In addition, variations in precipitation and mean temperature could directly affect fuel water status, and consequently flammability, and length of critical periods of high ignition danger for Mediterranean ecosystems. The main aim of this work was to propose a methodology for evaluating possible impacts of future climate change on moisture dynamic and length of fire danger period at local scale. Specific objectives were: i) evaluating performances of meteorological drought indices in describing seasonal pattern of live fuel moisture content (LFMC), and ii) simulating the potential impacts of future climate changes on the duration of fire danger period. Measurements of LFMC seasonal pattern of three Mediterranean shrub species were performed in North Western Sardinia (Italy) for 8 years. Seasonal patterns of LFMC were compared with the Drought Code of the Canadian Forest Fire Weather Index and the Keetch-Byram Drought Index. Analysis of frequency distribution and cumulative distribution curves were carried out in order to evaluate performance of codes and to identify threshold values of indices useful to determine the end of the potential fire season due to fuel status. A weather generator linked to climate change scenarios derived from 17 available General Circulation Models (GCMs) was used to produce synthetic weather series, representing present and future climates, for four selected sites located in North Sardinia, Italy. Finally, impacts of future climate change on fire season length at local scale were simulated. Results confirmed that the projected climate scenarios over the Mediterranean area will determine an overall increase of the fire season length.

This study (a) examined the relationships between "top performing" US hospitals and the health status of counties they serve and (b) compared the health status of "top performing" US hospital counties versus that of remaining US counties. Statistical analyses considered US News and World Report Honor Roll ranking data, as a measure of hospital performance, and County Health Rankings (CHR) data, as a measure of county health status. "Top performing" hospital Honor Roll scores were correlated with measures of Clinical Care (p < 0.001). Counties with "top performing" US hospitals presented greater health status with regard to All Health Outcomes (p < 0.001), Length of Life (p < 0.001), Quality of Life (p < 0.001), All Health Factors (p < 0.001), Health Behaviors (p < 0.001), and Clinical Care (p < 0.001), than compared to remaining US counties. Hospital impact on county health status remains primarily recognized in clinical care and not in overall health. Also, counties that contain a "top performing" US hospital tend to present lower health risks to their citizens than compared to other US counties.

The paradigm shift in recent years towards sustainable and coherent water resources management on a river basin scale has changed the subject of investigations to a multi-scale problem representing a great challenge for all actors participating in the management process. In this regard, planning engineers often face an inherent conflict to provide reliable decision support for complex questions with a minimum of effort. This trend inevitably increases the risk to base decisions upon uncertain and unverified conclusions. This paper proposes an adaptive framework for integral planning that combines several concepts (flow balancing, water quality monitoring, process modelling, multi-objective assessment) to systematically evaluate management strategies for water quality improvement. As key element, an S/P matrix is introduced to structure the differentiation of relevant 'pressures' in affected regions, i.e. 'spatial units', which helps in handling complexity. The framework is applied to a small, but typical, catchment in Flanders, Belgium. The application to the real-life case shows: (1) the proposed approach is adaptive, covers problems of different spatial and temporal scale, efficiently reduces complexity and finally leads to a transparent solution; and (2) water quality and emission-based performance evaluation must be done jointly as an emission-based performance improvement does not necessarily lead to an improved water quality status, and an assessment solely focusing on water quality criteria may mask non-compliance with emission-based standards. Recommendations derived from the theoretical analysis have been put into practice.

Background: There are many different scales to measure socioeconomic status (SES). The present study was conducted with the objective to compare the most commonly used SES in rural and urban setting. Materials and Methods: This exploratory study was conducted in the rural and urban field practice area of a medical college situated in Bangalore for a period of 3 months between January and April 2010. Statistical Analysis Used: To measure the agreement between the scales spearman's rank correlations was applied. Results: A total of 120 families were included in the study. Among the 60 families surveyed at rural setting, it was observed that, majority 40 (67%) belonged to high class when the Standard of Living Index (SLI) scale was applied. Among the 60 families surveyed at urban setting, majority 30 (50%) belonged to high class when the SLI scale was applied. Conclusions: The SLI scale gives a more accurate and realistic picture of the SES of the family and hence should be the scale recommended for classification of SES in urban and rural setting.

Performing a cognitive task while walking results in a reduction of walking performance among persons with MS. To date, very little is known about correlates of this dual task cost (DTC) of walking in MS. We examined walking performance, cognitive processing speed, and symptoms of fatigue, depression, anxiety, and pain as correlates of DTC of walking in MS. 82 persons with MS undertook a 6-min walk test (6MWT) and completed the Symbol Digit Modalities Test (SDMT), Fatigue Severity Scale (FSS), Short-form of the McGill Pain Questionnaire (SF-MPQ), Hospital Anxiety and Depression Scale (HADS), and self-reported Expanded Disability Status Scale (SR-EDSS). The participants completed 4 trials of walking at a self-selected pace on an electronic walkway that recorded spatiotemporal parameters of gait. The first 2 trials were performed without a cognitive task, whereas the second 2 trials were completed while performing a modified Word List Generation task. There were significant and large declines in gait performance with the addition of a cognitive task for velocity (p<.001, η2=.52), cadence (p<.001, η2=.49), and step length (p<.001, η2=.23). 6MWT and SDMT scores correlated with DTC for velocity (r=-.41, p<.001 and r=-.32, p<.001, respectively) and step length (r=-.45, p<.001 and r=-.37, p<.001, respectively); there were no significant associations between FSS, SF-MPQ, and HADS scores with the DTC of walking. Regression analyses indicated that 6MW, but not SDMT, explained variance in DTC for velocity (ΔR2=.11, p<.001) and step length (ΔR2=.13, p<.001), after controlling for SR-EDSS scores. Walking performance might be a target of interventions for reducing the DTC of walking in MS. Copyright © 2013 Elsevier B.V. All rights reserved.

Endovascular therapy is increasingly used in acute ischemic stroke treatment and is now considered the gold standard approach for selected patient populations. Prior studies have demonstrated that eventual patient outcomes depend on both patient-specific factors and procedural considerations. However, these factors remain unclear for acute basilar artery occlusion stroke. We sought to determine prognostic factors of good outcome in acute posterior circulation large vessel occlusion strokes treated with endovascular therapy. We reviewed our prospectively collected endovascular databases at 2 US tertiary care academic institutions for patients with acute posterior circulation strokes from September 2005 to September 2015 who had 3-month modified Rankin Scale documented. Baseline characteristics, procedural data, and outcomes were evaluated. A good outcome was defined as a 90-day modified Rankin Scale score of 0 to 2. The association between clinical and procedural parameters and functional outcome was assessed. A total of 214 patients qualified for the study. Smoking status, creatinine levels, baseline National Institutes of Health Stroke Scale score, anesthesia modality (conscious sedation versus general anesthesia), procedural length, and reperfusion status were significantly associated with good outcomes in the univariate analysis. Multivariate logistic regression indicated that only smoking (odds ratio=2.61; 95% confidence interval, 1.23-5.56; P =0.013), low baseline National Institutes of Health Stroke Scale score (odds ratio=1.09; 95% confidence interval, 1.04-1.13; P <0.0001), and successful reperfusion status (odds ratio=10.80; 95% confidence interval, 1.36-85.96; P =0.025) were associated with good outcome. In our retrospective case series, only smoking, low baseline National Institutes of Health Stroke Scale score, and successful reperfusion status were associated with good outcome in patients with posterior circulation stroke treated with endovascular therapy. © 2017 American Heart Association, Inc.

Within the context of the Advanced Cognitive Training for Independent and Vital Elderly study (ACTIVE; Ball et al., 2002; Jobe et al., 2001; Willis et al., 2006), we examined the longitudinal association of baseline depressive symptoms on inductive reasoning performance over a 10-year period between the reasoning training and control conditions (N = 1,375). At baseline, 322 participants (23%) reported elevated depressive symptoms, defined by a score ≥9 on the 12-item version of the Center for Epidemiological Studies Depression Scale (CES-D; Mirowsky & Ross, 2003; Radloff, 1977). Differences in baseline depressive status were not associated with immediate posttraining gains or with subsequent annual change in reasoning performance, suggesting that the presence of elevated baseline depressive symptoms does not impact the ability to benefit from reasoning training.

Depression, chronic pain and sleep disturbances frequently co-exist in FM and have shown to be independently related with suicidal behaviours. The present survey was performed to evaluate the prevalence of previous suicide attempts in patients with FM and its potential relationship with sociodemographic and clinical characteristics of the disease. A concise survey was sent to patients of seven associations of patients with FM. In addition to the inquiry concerning the number, if any, and characteristics of suicide attempts, the survey included questions about sociodemographic and clinical data of patients as well as the revised FM impact questionnaire (FIQR) and the Plutchik suicide risk scale. One hundred and eighty patients answered the survey. Thirty (16.7%) of them reported one to three previous suicide attempts. Drug poisoning was the most frequently employed method for suicide attempt (70%). No relevant differences were found between suicide attempters and non-attempters in relation to age, education and marital status, but a significant difference was found in relation to employment status. Plutchik's scale scores, both in suicide attempters and non-attempters, were higher than those found in the literature. FIQR scores were significantly higher in suicide attempters than in non-attempters. A high-positive correlation was found between FIQR and Plutchik suicide risk scale scores. Pain, poor sleep quality, anxiety and depression were positively correlated with suicide risk. FM is associated with an increased risk of suicide and suicide attempts. Suicidal behaviour seems to be related with the global severity of the disease.

Xeroderma pigmentosum (XP) is a rare autosomal recessive hereditary disease. Patients with XP have severe hypersensitivity to sunlight, resulting in skin cancers, and some patients have neurological symptoms. In Japan, XP complementation group A (XP-A) is the most common form, and it is associated with severe neurological symptoms. We performed a nationwide survey on XP to determine the present status of XP in Japan. The distribution of complementation groups in Japan was considerably different from that in other countries, but there was a higher frequency in group A and the variant type, which is similar to previous reports in Japan. Basal cell carcinoma was the most frequent skin cancer that patients with XP developed, followed by squamous cell carcinoma and malignant melanoma. The frequency of these skin cancers in patients with XP-A has decreased, and these skin cancers have been occurring in much older people than those previously observed. Diagnosing XP in patients at younger ages seems to encourage patients and their parents to use sun protection, which helps prevent skin cancer. We also created a tentative scale for classifying the severity of XP, and we evaluated the neurological symptoms of XP-A using this severity scale. Our classification correlated well with patients' age, suggesting that it may be useful and feasible in clinical practice to assess the progression of symptoms of each patient with XP and evaluate the effects of treatment in the future. © 2016 John Wiley & Sons A/S.

Objectives To elucidate the association between antiplatelet use in patients with non-haemorrhagic moyamoya disease before hospital admission and good functional status on admission in Japan. Design Retrospective, multicentre, non-randomised, observational study. Setting Nationwide registry data in Japan. Participants A total of 1925 patients with non-haemorrhagic moyamoya disease admitted between 1 April 2012 and 31 March 2014 in Japan. Main outcome measure We performed propensity score-matched analysis to examine the association between prehospital antiplatelet use and no significant disability on hospital admission, as defined by a modified Rankin Scale score of 0 or 1. Results Propensity-matched patients who received prehospital antiplatelet drugs were associated with a good outcome on hospital admission (OR adjusted for all covariates, 3.82; 95% CI 1.22 to 11.99) compared with those who did not receive antiplatelet drugs prior to hospital admission. Conclusions Prehospital antiplatelet use was significantly associated with good functional status on hospital admission among patients with non-haemorrhagic moyamoya disease in Japan. Our results suggest that prehospital antiplatelet use should be considered when evaluating outcomes of patients with non-haemorrhagic moyamoya disease. PMID:27008684

Background There is evidence that poverty, health and nutrition affect children's cognitive development. This study aimed to examine the relative contributions of both proximal and distal risk factors on child cognitive development, by breaking down the possible causal pathways through which poverty affects cognition. Methods This cohort study collected data on family socioeconomic status, household and neighbourhood environmental conditions, child health and nutritional status, psychosocial stimulation and nursery school attendance. The effect of these on Wechsler Pre-School and Primary Scale of Intelligence scores at five years of age was investigated using a multivariable hierarchical analysis, guided by the proposed conceptual framework. Results Unfavourable socioeconomic conditions, poorly educated mother, absent father, poor sanitary conditions at home and in the neighbourhood and low birth weight were negatively associated with cognitive performance at five years of age, while strong positive associations were found with high levels of domestic stimulation and nursery school attendance. Conclusion Children's cognitive development in urban contexts in developing countries could be substantially increased by interventions promoting early psychosocial stimulation and preschool experience, together with efforts to prevent low birth weight and promote adequate nutritional status.

Introduction: Rheumatoid Arthritis (RA) is a systemic, autoimmune and inflammatory disease with an unknown etiology that is associated with progressive joint degeneration, limitation of physical activity and disability. The aim of the study was to evaluate self-management behaviors and their associated factors in RA patients. Material and Method: This cross-sectional study was performed in 2013 on 185 patients in Iran. Data were selected through convenient sampling. The collected data included demographic variables, disease related variables, Arthritis Impact Measurement Scale 2 (AIMS-2SF), and Self-Management Behaviors (SMB). Data were analyzed by SPSS17 using Spearman correlation and logistic regression test. Result: In this study drug management, regular follow-up, and food supplement were used as the most frequently applied SMB and aquatic exercise, diet, massage therapy, and relaxation were the least common SMBs. Age, education, health status, occupation, marital status, sex, DAS28 (Disease Activity Score 28 joints), and PGA (Physician Global Assessment) were significantly related with SMB. Conclusion: The result of the study highlight the influence of demographic variables, health status, and disease related data on SMB. Thus, more studies are required to find factors influencing SMB in order to improve SMB. PMID:26493424

Mental disorders have been found to be the main cause of maladjustment and early discharge of the personnel in the Hellenic Navy and the armed forces in general. This study investigates the mental health status of a warship's military personnel by use of a widely used self-administered scale. The 28-item Greek version of the General Health Questionnaire was administered to 281 men aboard a Greek warship to determine their mental health status and to examine possible associations with sociodemographic variables (rank, educational level, marital status). A high prevalence of General Health questionnaire cases (48.8%) was found which indicated conscripts as the group with the greater tendency for problems of adjustment and performance among the personnel of the warship. A negative association was found between educational level and psychological distress, whereas married subjects were found to have better levels of psychological well-being as defined by lower General Health questionnaire scores, compared with unmarried subjects. Although a further methodological and more sophisticated inquiry is necessary, the findings of the present study could be useful for the design of mental health interventions in the naval and the military setting.

The quantification of uncertainties in design and safety analysis of reactors is today not only broadly accepted, but in many cases became the preferred way to replace traditional conservative analysis for safety and licensing analysis. The use of a more fundamental methodology is also consistent with the reliable high fidelity physics models and robust, efficient, and accurate codes available today. To facilitate uncertainty analysis applications a comprehensive approach and methodology must be developed and applied, in contrast to the historical approach where sensitivity analysis were performed and uncertainties then determined by a simplified statistical combination of a few important inputmore » parameters. New methodologies are currently under development in the OECD/NEA Light Water Reactor (LWR) Uncertainty Analysis in Best-Estimate Modelling (UAM) benchmark activity. High Temperature Gas-cooled Reactor (HTGR) designs require specific treatment of the double heterogeneous fuel design and large graphite quantities at high temperatures. The IAEA has therefore launched a Coordinated Research Project (CRP) on HTGR Uncertainty Analysis in Modelling (UAM) in 2013 to study uncertainty propagation specifically in the HTGR analysis chain. Two benchmark problems are defined, with the prismatic design represented by the General Atomics (GA) MHTGR-350 and a 250 MW modular pebble bed design similar to the Chinese HTR-PM. Work has started on the first phase and the current CRP status is reported in the paper. A comparison of the Serpent and SCALE/KENO-VI reference Monte Carlo results for Ex. I-1 of the MHTGR-350 design is also included. It was observed that the SCALE/KENO-VI Continuous Energy (CE) k ∞ values were 395 pcm (Ex. I-1a) to 803 pcm (Ex.

The use of the latest ENDF-B-VII.1 cross section library in Serpent lead to ~180 pcm lower k ∞ values compared to the older ENDF-B-VII.0 dataset, caused by the modified graphite neutron capture cross section.

The Atmospheric Infrared Sounder (AIRS) is a hyperspectral infrared instrument on the EOS Aqua Spacecraft, launched on May 4, 2002. AIRS has 2378 infrared channels ranging from 3.7 μm to 15.4 μm and a 13.5 km footprint at nadir. AIRS is a "facility" instrument developed by NASA as an experimental demonstration of advanced technology for remote sensing and the benefits of high resolution infrared spectra to science investigations. AIRS, in conjunction with the Advanced Microwave Sounding Unit (AMSU), produces temperature profiles with 1K/km accuracy on a global scale, as well as water vapor profiles and trace gas amounts for CO2 , CO, SO2 , O3 and CH4. AIRS data are used for weather forecasting, climate process studies and validating climate models. The AIRS instrument has far exceeded its required design life of 5 years, with nearly 13 years of routine science operations that began on August 31, 2002. While the instrument has performed exceptionally well, with little sign of wear, the AIRS Project continues to monitor and maintain the health of AIRS, characterize its behavior and improve performance where possible. Radiometric stability has been monitored and trending shows better than 16 mK/year stability. Spectral calibration stability is better than 1 ppm/year. At this time we expect the AIRS to continue to perform well into the next decade. This paper contains updates to previous instrument status reports, with emphasis on the last three years.

Eye-closure-triggered paroxysmal activity and cognitive impairment: a case report.

To study the neuropsychological status of an epileptic patient presenting with epileptic activity triggered by eye closure in a 14-year follow-up period. The patient was studied at 12 and 26 years of age; during this period he underwent periodical clinical evaluations and EEG investigations; brain magnetic resonance imaging (MRI) was performed at 12 years of age. A neuropsychological assessment was carried out both at 12 years of age (T0) and at 26 years of age. At T0 and T1, neuropsychological tests (digits and words span, graphoestesia, reactions time to auditory stimuli, sentences repetition, words repetition, digital gnosis, backward counting [i.e.,100-0]) were performed during video-EEG monitoring either with eyes closed or with eyes open, to evaluate possible transitory effects related to ongoing epileptic activity. Moreover, at T0 the patient underwent Wechsler Intelligence Scale for Children-Revised, and at T1 to Wechsler Adult Intelligence Scale-Revised. EEG recordings showed continuous epileptic activity triggered by eye closure, disappearing only with eyes opening, both at T0 and T1 (in this latter case, anteriorly predominant). The results of neuropsychological assessment during eyes closed as compared to performances with eyes open did not show significant differences, at T0 as well as at T1. Wechsler Intelligence scales showed a deterioration of performances at T1 with respect to T0; in addition, at T1, attention and short-term memory abnormalities, impairment in facial recognition and block design, and defective results in Continuous Performance Test and Wisconsin Card Sorting Test were observed. Lack of differences between the results of neuropsychological tests performed with eyes closed as compared to the eyes open condition suggests that in our patient epileptic activity did not cause transitory cognitive abnormalities. Deterioration of Wechsler Intelligence Scales in the follow-up period might be interpreted as the result of a disruption of cognitive processes possibly related to the persistence of a continuous epileptic activity during eye closure over the years. We speculate whether a dysfunction in posterior cortical areas involved in visual processing might be related to the impairment in face recognition and block design tests as well to eye closure sensitivity.

While most recent breakthroughs in scientific research rely on complex simulations carried out in large-scale supercomputers, the power draft and energy spent for this purpose is increasingly becoming a limiting factor to this trend. In this paper, we provide an overview of the current status in energy-efficient scientific computing by reviewing different technologies used to monitor power draft as well as power- and energy-saving mechanisms available in commodity hardware. For the particular domain of sparse linear algebra, we analyse the energy efficiency of a broad collection of hardware architectures and investigate how algorithmic and implementation modifications can improve the energy performance of sparse linear system solvers, without negatively impacting their performance. © 2014 The Author(s) Published by the Royal Society.

The present status and flight-test results are presented for the ATLIT airplane. The ATLIT is a Piper PA-34 Seneca I modified by the installation of new wings incorporating the GA(W)-1 (Whitcomb) airfoil, reduced wing area, roll-control spoilers, and full-span Fowler flaps. Flight-test results on stall and spoiler roll characteristics show good agreement with wind-tunnel data. Maximum power-off lift coefficients are greater than 3.0 with flaps deflected 37 deg. With flaps down, spoiler deflections can produce roll helix angles in excess of 0.11 rad. Flight testing is planned to document climb and cruise performance, and supercritical propeller performance and noise characteristics. The airplane is scheduled for testing in the NASA-Langley Research Center Full-Scale Tunnel.

Iron nutrition and premenopausal women: effects of poor iron status on physical and neuropsychological performance.

PubMed

McClung, James P; Murray-Kolb, Laura E

2013-01-01

Iron is a nutritionally essential trace element that functions through incorporation into proteins and enzymes, many of which contribute to physical and neuropsychological performance. Poor iron status, including iron deficiency (ID; diminished iron stores) and iron deficiency anemia (IDA; poor iron stores and diminished hemoglobin), affects billions of people worldwide. This review focuses on physical and neuropsychological outcomes associated with ID and IDA in premenopausal women, as the prevalence of ID and IDA is often greater in premenopausal women than other population demographics. Recent studies addressing the physiological effects of poor iron status on physical performance, including work productivity, voluntary activity, and athletic performance, are addressed. Similarly, the effects of iron status on neurological performance, including cognition, affect, and behavior, are summarized. Nutritional countermeasures for the prevention of poor iron status and the restoration of decrements in performance outcomes are described.

The present study attempted to assess factors associated with positive anti-HCV among patients with skin diseases. A retrospective analysis of 3,496 subjects' history profiles from the HCV antibody surveillance projects performed from 2000 to 2007. Only 150 subject profiles with skin diseases were included in the analysis of factors associated with positive anti-HCV Patient profiles including socio-demographic parameters, the main risk behavior or risk exposure, types of skin diseases, anti-HIV status, and results of anti-HCV were analyzed using Chi-square test or Fisher's exact test. Results revealed that only 10 from 150 studied patients (6.7%) were positive for anti-HCV antibody. Patient profiles including socio-demographic parameters, the main risk behavior or risk exposure, types of skin diseases, and anti-HIV status among patients with or without anti-HCV were compared and analyzed to assess factors associated with positive anti-HCV. It was found that patient's income, types of skin disease, and anti-HIV status were significantly associated with positive anti-HCV among this group, p = 0.0240, p = 0.0053 and p = 0.0462, respectively. This analysis found three studied factors including patient's income, types of skin disease, and anti-HIV status to be significantly associated with HCV infection in patients with skin diseases. However, a large-scale work should be done to confirm the present study.

Because of heavy dependence on fish, Amazonian riparian communities are chronically exposed to high levels of methylmercury (MeHg). We studied fish-MeHg exposure (total hair-Hg, HHg) as a determinant of neurocognitive scores of children living in two geographically distant, culturally distinct and isolated poor communities of non-urban environments: Amazonian riverines (Riparians, n=38) of the Puruzinho Lake community in the Rio Madeira Basin and rural agrarians from Iúna, Espírito Santo (Agrarians, n=32). Nutritional status was estimated by anthropometry (Z-scores) and individual cognitive abilities were assessed by the Wechsler Intelligence Scale for Children-III (WISC-III) and the Human Figure Drawings (HFD), both validated versions for Brazilian children. Anthropometric assessment showed slightly elevated Z-scores for the Agrarian children (not statistically significant) but median HHg concentrations were 14.4 and 0.25microgg(-1) respectively for Riparian and Agrarian children (p=0.000). Despite paradoxical MeHg exposures, both groups showed comparable HFD scores but very poor performance in WISC-III test battery; median of sum of WISC-III subtests scores (SigmaTOT) were 17.9 and 28.6 (p<0.000) for Riparian and Agrarian children, respectively (percentage scale). Spearman correlation between nutritional status (attained growth) and psychometric scores were statistically significant between height-for-age Z-score and Object Assembly subtest (r=0.269; p=0.043), SigmaTOT (r=0.319; p=0.016), Performance-IQ (r=0.311; p=0.019) and Perceptual Organization Index scores (r=0.302; p=0.023). In these isolated communities there are stronger determinants of neurocognitive poor performance than MeHg exposure. Global strategies for reducing human exposure to MeHg by curtailing fish consumption are unrealistic options for riverine subsistence populations and are not justifiable to prevent low cognitive scores.

Overwhelming evidence, including three clinical trials, shows that male circumcision (MC) reduces the risk of HIV infection among men. However, data from recent Lesotho Demographic and Health Surveys do not demonstrate MC to be protective against HIV. These contradictory findings could partially be due to inaccurate self-reported MC status used to estimate MC prevalence. This study describes MC characteristics among men applying for Lesotho Defence Force recruitment and seeks to assess MC self-reported accuracy through comparison with physical-examination-based data. During Lesotho Defence Force applicant screening in 2009, 241 (77%) of 312 men, aged 18-25 y, consented to a self-administered demographic and MC characteristic survey and physician-performed genital examination. The extent of foreskin removal was graded on a scale of 1 (no evidence of MC) to 4 (complete MC). MC was self-reported by 27% (n = 64/239) of participants. Of the 64 men self-reporting being circumcised, physical exam showed that 23% had no evidence of circumcision, 27% had partial circumcision, and 50% had complete circumcision. Of the MCs reportedly performed by a medical provider, 3% were Grade 1 and 73% were Grade 4. Of the MCs reportedly performed by traditional circumcisers, 41% were Grade 1, while 28% were Grade 4. Among participants self-reporting being circumcised, the odds of MC status misclassification were seven times higher among those reportedly circumcised by initiation school personnel (odds ratio = 7.22; 95% CI = 2.29-22.75). Approximately 27% of participants self-reported being circumcised. However, only 50% of these men had complete MC as determined by a physical exam. Given this low MC self-report accuracy, countries scaling up voluntary medical MC (VMMC) should obtain physical-exam-based MC data to guide service delivery and cost estimates. HIV prevention messages promoting VMMC should provide comprehensive education regarding the definition of VMMC.

Participants Convenience and snowball sampling methods were used to survey caregivers of 395 children (93 children with developmental disabilities and delays, 302 without developmental disabilities and delays) between 0–5 years (mean = 35.33 months, SD = 20.29) and residing in North America. Interventions Not applicable. Main Outcome Measure(s) The YC-PEM includes three participation scales and one environment scale. Each scale is assessed across three settings: home, daycare/preschool, and community. Data were analyzed to derive estimates of internal consistency, test-retest reliability, and construct validity. Results Internal consistency ranged from .68 to .96 and .92 to .96 for the participation and environment scales, respectively. Test-retest reliability (2–4 weeks) ranged from .31 to .93 for participation scales and from .91 to .94 for the environment scale. One of three participation scales and the environment scale demonstrated significant group differences by disability status across all three settings, and all four scales discriminated between disability groups for the daycare/preschool setting. The participation scales exhibited small to moderate positive associations with functional performance scores. Conclusion(s) Results lend initial support for the use of the YC-PEM in research to assess the participation of young children with disabilities and delays in terms of 1) home, daycare/preschool, and community participation patterns, 2) perceived environmental supports and barriers to participation, and 3) activity-specific parent strategies to promote participation.

The main aims of this study were to (i) investigate the emotional disorder status of patients with burning mouth syndrome (BMS) and (ii) detect regional cerebral blood flow in BMS patients with the application of combined single-photon emission computed tomography and computed tomography (SPECT/CT). The degree of pain was measured using the visual analysis scale, and emotional disorder with the self-rating anxiety scale, self-rating depression scale, and Hamilton depression rating scale in 29 patients with BMS and 10 healthy controls. SPECT/CT was performed in 29 patients with BMS and 10 healthy controls, and statistical parametric mapping method was used for between-group analyses. The incidence rate of depression in patients with BMS was 31.0%. Compared to the control group, patients with BMS displayed significantly different depression and anxiety scales (P < 0.05). Significantly lower regional cerebral blood flow in the left parietal and left temporal lobes was recorded for BMS patients with depression (P < 0.05). Patients with BMS experience more depression and anxious emotion. Moreover, depression in patients with BMS may be associated with lower regional cerebral blood flow in the left temporal and left parietal lobes. © 2015 John Wiley & Sons A/S.

The purpose of this study was to examine the current status of home care nursing services provided by community health nurses and to identify barriers to the services. A cross-sectional survey was conducted with three types of community health care nurses. Participants were 257 nurses, 46 of whom were hospital based home care nurses, 176 were community based visiting nurses, and 35 were long term care insurance based visiting nurses. A structured questionnaire on 7 domains of home care nursing services with a 4-point Likert scale was used to measure activities and barriers to care. Data were analyzed using SPSS WIN 21.0 program. Hospital based home care nurses showed a high level of service performance activity in the domain of clinical laboratory tests, medications and injections, therapeutic nursing, and education. Community based visiting nurses had a high level of service performance in the reference domain. Long term care insurance based visiting nurses showed a high level of performance in the service domains of fundamental nursing and counseling. The results show that although health care service provided by the three types of community health nurse overlapped, the focus of the service is differentiated. Therefore, these results suggest that existing home care services will need to be utilized efficiently in the development of a new nursing care service for patients living in the community after hospital discharge.

We performed a comparative study of a health education programme that was delivered either through one-way communication with printed media, or through interactive videophone interviews. We aimed to ascertain which mode of counselling, when used in combination with telemonitoring, is more effective at lifestyle modification intended to improve health status. Participants, who were residents of Kurihara city in Miyagi prefecture, Japan, were randomized into two groups: one group received individualized monthly documented reports (n = 33; 22 females; average age: 67.2 years), and the other received interactive videophone communication (n = 35; 22 females; average age: 65.1 years) for three months. Telemonitoring was conducted on both groups, using a pedometer, weighing scale and a sphygmomanometer. Pre- and post-intervention, anthropometric measurements and blood tests were performed; the participants also completed self-administered questionnaires. The two groups showed similar degrees of health status improvement and satisfaction levels. However, the participants in the videophone group were more aware of improvements in their lifestyles than were the participants in the document group. The individualized printed communication programme was less time-consuming compared to videophone communication. Further studies are needed to formulate a balanced protocol for a counselling-cum-telemonitoring programme that provides optimal health improvement and cost performance with the available human resources. © The Author(s) 2015.

The purpose of this cross sectional study was to estimate the contributions of potentially modifiable physical factors to variations in perceived health status in knee osteoarthritis (OA) patients referred for physical therapy. Health status was measured by three questionnaires: Knee injury and Osteoarthritis Outcome Score (KOOS); Knee Outcome Survey - Activities of Daily Living Scale (KOS-ADLS); and Medical Outcomes Study - 36 item Short Form (SF-36). Physical factors were measured by a battery of tests: body mass index (BMI); visual analog scale (VAS) of pain intensity; isometric dynamometry; universal goniometry; step test (ST); timed "up and go" test (TUGT); 20-meter walk test (20MWT); and 6-minute walk test (6MWT). All tests were administered to 136 subjects with symptomatic knee OA (94 females, 42 males; age: 67.2 ± 7.1 years). Multiple stepwise regression analyses revealed that knee muscle strength, VAS of pain intensity, 6MWT, degree of knee flexion and BMI were moderate predictors of health status. In the final models, selected combinations of these potentially modifiable physical factors explained 22% to 37% of the variance in KOOS subscale scores, 40% of the variance in the KOS-ADLS scale score, and 21% to 34% of the variance in physical health SF-36 subscale scores. More research is required in order to evaluate whether therapeutic interventions targeting these potentially modifiable physical factors would improve health status in knee OA patients.

60 male Nigerian prison inmates (30 with convicted status and 30 awaiting trial) and 210 male noninmates were administered the Tennessee Self-concept Scale to test the hypotheses that (1) inmates with convicted status would obtain higher self-concept scores than those with ¿awaiting trial¿ status, and (2) the self-concept scores of prison inmates generally would be lower than those of noninmates. The two hypotheses were strongly supported for this sample. It was concluded that self-concept scores were not only related to delinquency by also to custodial status.

Multiple sclerosis is a chronic, inflammatory, demyelinating disease of the central nervous system, which is characterized by diverse symptomatology. Most often affects people at a young age gradually leading to their disability. Looking for new therapies to alleviate neurological deficits caused by the disease. One of the alternative methods of therapy is high - tone power therapy. The article is a comparison of high-tone power therapy and kinesis in improving patients with multiple sclerosis. The aim of this study was to evaluate the effectiveness of high-tone power therapy and exercises in kinesis on the functional status of patients with multiple sclerosis. The study involved 20 patients with multiple sclerosis, both sexes, treated at the Department of Rehabilitation and Physical Medicine in Lodz. Patients were randomly divided into two groups studied. In group high-tone power therapy applied for 60 minutes, while in group II were used exercises for kinesis. Treatment time for both groups of patients was 15 days. To assess the functional status scale was used: Expanded Disability Status Scale of Kurtzke (EDSS), as well as by Barthel ADL Index. Assessment of quality of life were made using MSQOL Questionnaire-54. For the evaluation of gait and balance using Tinetti scale, and pain VAS rated, and Laitinen. Changes in muscle tone was assessed on the basis of the Ashworth scale. Both group I and II improved on scales conducted before and after therapy. In group I, in which the applied high-tone power therapy, reported statistically significant results in 9 out of 10 tested parameters, while in group II, which was used in the exercises in kinesis an improvement in 6 out of 10 tested parameters. Correlating the results of both the test groups in relation to each other did not show statistically significant differences. High-Tone Power Therapy beneficial effect on the functional status of patients with multiple sclerosis. Obtaining results in terms of number of tested parameters allows for the use of this therapy in the comprehensive improvement of patients with multiple sclerosis. Exercises from the scheme kinesis favorable impact on the functional status of patients with MS and are essential in the rehabilitation of these patients. In any group, no adverse effects were observed.

The objective of this descriptive study is to explore the relationships between pain, sleep disturbance, and quality of life among Palestinian patients diagnosed with cancer in the West Bank. A cross-sectional, descriptive-correlational design was used to collect data from 184 patients with cancer. The quality of life questionnaire, visual analogue pain scale, and physical health status were used in data collection. The results showed that the mean score for pain was 5, the best functioning was for cognitive scale (M = 75, SD = 29), the worst symptoms experienced by patients was appetite loss (M = 47, SD = 35), a moderate global health status (M = 53, SD = 27), and the mean for sleep disturbance was 43 (SD = 35). Pain and sleep disturbance showed high negative correlations with functional scales of quality of life and positive with symptom scales. The findings showed that the co-occurrence of pain and sleep disturbance was negatively correlated with quality of life (QoL) and positively with symptom scales. The regression analysis revealed that pain and sleep disturbance accounted for a significant proportion of variance in the QoL (p < 0.001), and the highest proportion was in predicting global health status (41.9 %). The findings of this study give evidence about the importance of assessing pain and sleep quality among Palestinian patients with cancer.

2009-04-01

The relationship between cognitive and functional abilities was examined in a sample of community-dwelling older adults. Self and informant (e.g., spouse) reports of participants' functional status were obtained on the modified Scales of Independent Behavior-Revised (mSIB-R). Participants also completed measures of processing speed, episodic memory, executive functioning, and verbal ability. Results showed that the mSIB-R correlated positively with cognitive variables. Hierarchical regression analyses suggested that each mSIB-R factor is predicted by somewhat different cognitive variables, after adjusting for demographic, health, and motor variables. This report-based measure was as accurate as a performance-based measure in classifying cognitive groups. Informant social/cognitive engagement and self physical/environment engagement factors showed the most promise in this regard. The findings reveal links between cognitive and functional abilities in a sample with varying degrees of cognitive impairment.

Despite decades of development of unstructured mesh methods, high-fidelity time-accurate simulations are still predominantly carried out on structured, or unstructured hexahedral meshes by using high-order finite-difference, weighted essentially non-oscillatory (WENO), or hybrid schemes formed by their combinations. In this work, the space-time conservation element solution element (CESE) method is used to simulate several flow problems including supersonic jet/shock interaction and its impact on launch vehicle acoustics, and direct numerical simulations of turbulent flows using tetrahedral meshes. This paper provides a status report for the continuing development of the space-time conservation element solution element (CESE) numerical and software framework under the Revolutionary Computational Aerosciences (RCA) project. Solution accuracy and large-scale parallel performance of the numerical framework is assessed with the goal of providing a viable paradigm for future high-fidelity flow physics simulations.

Assessing social competence is important for clinical and preventive interventions of depression. The aim of the present paper was to examine the factor structure of the Japanese Interpersonal Competence Scale (JICS). Exploratory and confirmatory factor analysis was performed on the survey responses of 730 participants. Simultaneous multigroup analyses were conducted to confirm factor stability across psychological health status and sex differences. Two factors, which represent Perceptive Ability and Self-Restraint, were confirmed to show a moderate correlation. Perceptive Ability involves a more cognitive aspect of social competence, while Self-Restraint involves a more behavioral aspect, both of which are considered to reflect the emotion-based relating style specific to the Japanese people: indulgent dependence (amae) and harmony (wa). In addition, Self-Restraint may be linked to social functioning. Both constructs may confound a respondent's perceived confidence. Despite its shortcomings, the JICS is a unique measure of social competence in the Japanese cultural context.

This paper reports development of the Family Management Measure (FaMM) of parental perceptions of family management of chronic conditions. By telephone interview, 579 parents of children age 3 to 19 with a chronic condition (349 partnered mothers, 165 partners, 65 single mothers) completed the FaMM and measures of child functional status and behavioral problems and family functioning. Analyses addressed reliability, factor structure, and construct validity. Exploratory factor analysis yielded six scales: Child's Daily Life, Condition Management Ability, Condition Management Effort, Family Life Difficulty, Parental Mutuality, and View of Condition Impact. Internal consistency reliability ranged from .72 to .91, and test-retest reliability from .71 to .94. Construct validity was supported by significant correlations in hypothesized directions between FaMM scales and established measures. Results support FaMM's; reliability and validity, indicating it performs in a theoretically meaningful way and taps distinct aspects of family response to childhood chronic conditions.

In the last decade, some attention has been given to spirituality and faith and their role in cancer patients' coping. Few data are available about spirituality among cancer patients in Southern European countries, which have a big tradition of spirituality, namely, the Catholic religion. As part of a more general investigation (Southern European Psycho-Oncology Study--SEPOS), the aim of this study was to examine the effect of spirituality in molding psychosocial implications in Southern European cancer patients. A convenience sample of 323 outpatients with a diagnosis of cancer between 6 to 18 months, a good performance status (Karnofsky Performance Status > 80), and no cognitive deficits or central nervous system (CNS) involvement by disease were approached in university and affiliated cancer centers in Italy, Spain, Portugal, and Switzerland (Italian speaking area). Each patient was evaluated for spirituality (Visual Analog Scale 0-10), psychological morbidity (Hospital Anxiety and Depression Scale--HADS), coping strategies (Mini-Mental Adjustment to Cancer--Mini-MAC) and concerns about illness (Cancer Worries Inventory--CWI). RESULTS. The majority of patients (79.3%) referred to being supported by their spirituality/faith throughout their illness. Significant differences were found between the spirituality and non-spirituality groups (p ≤ 0.01) in terms of education, coping styles, and psychological morbidity. Spirituality was significantly correlated with fighting spirit (r = -0.27), fatalism (r = 0.50), and avoidance (r = 0.23) coping styles and negatively correlated with education (r = -0.25), depression (r = -0.22) and HAD total (r = -0.17). Spirituality is frequent among Southern European cancer patients with lower education and seems to play some protective role towards psychological morbidity, specifically depression. Further studies should examine this trend in Southern European cancer patients.

Limited information was focused on perimenopausal syndrome and mood disorders (depression and anxiety) in a specific population: perimenopausal women. We aimed to investigate the prevalence and severity of perimenopausal syndrome and mood disorders, and to analyze their relationships and risk factors in perimenopausal women in Shanghai, China.A cross-sectional study was performed on 1062 women aged 40 to 60 years from 3 communities. The general conditions questionnaire, Kupperman index, self-rating depression scale, and self-rating anxiety scale were used. A multivariable logistic regression analysis was performed to identify risk factors for perimenopausal syndrome and mood disorders.The prevalence of perimenopausal syndrome, depression and anxiety, which were primarily associated with mild symptoms, was 10.92%, 25.99%, and 12.62%, respectively. The differences in the prevalence and severity of perimenopausal syndrome, in the prevalence of depression, and in the severity of anxiety in different age groups were statistically significant (P < 0.001, P = 0.028, P = 0.003, P = 0.002, respectively). The relationships between perimenopausal syndrome and mood disorders were strong and positive (P < 0.001). It was found that age, employment status, personality characteristics, menstruation, and constipation were risk factors for perimenopausal syndrome, but monthly household income was a protective factor. Also, higher income and better medical insurance were beneficial to depression. However, disharmonious family relationships, irregular menstruation, constipation, and severity of perimenopausal syndrome were harmful to depression. For anxiety, attitudes to children status, cesarean section times, and constipation were risk factors.We concluded that perimenopausal syndrome and mood disorders are common in perimenopausal women in Shanghai, whose associations are strong and positive. Many risk factors are associated with and shared between perimenopausal syndrome and mood disorders. Therefore, appropriate management of perimenopause is needed to alleviate the conditions.

Neurodevelopmental dysfunction is increasingly recognized as a common outcome of congenital heart defects and their treatment in infancy. The effects of the intensive care unit (ICU) experience and environment on these infants are unknown and potentially modifiable, but no validated metric is available for objective evaluation of early motor impairments in the ICU/hospital setting. The purpose of this study was to characterize the motor status of hospitalized infants after cardiac operations, including the development and field-testing of the Congenital Heart Assessment of Sensory and Motor Status (CHASMS) metric. CHASMS item generation was based on review of the literature, focused interviews with parents, and expert consensus. A nurse administered CHASMS to 100 infants aged younger than 10 months old undergoing cardiac operations. Preoperative and postoperative CHASMS scores were compared, and associations between CHASMS scores and patient characteristics were examined. Physical therapists assessed neuromotor skills by using the Test of Infant Motor Performance or the Alberta Infant Motor Scales for correlation with CHASMS scores. CHASMS gross motor scores declined postoperatively in 64% (25 of 39). Lower CHASMS scores, after adjusting for age, were associated with longer duration of mechanical ventilation (p < 0.001) and ICU length of stay (p = 0.001). Gross motor CHASMS scores were significantly correlated with Test of Infant Motor Performance (r = 0.70, p < 0.001) and Alberta Infant Motor Scales scores (r = 0.88, p < 0.001). Motor impairments in infants after cardiac operations are common and may be exacerbated by longer intubation and prolonged exposure to the ICU environment. The feasibility, reliability, and validity of CHASMS were supported for the evaluation of motor skills in this at-risk population. Copyright © 2017 The Society of Thoracic Surgeons.

Sleep disturbance is a problem for oncology patients. To evaluate how sleep disturbance and daytime sleepiness (DS) changed from before to six months following surgery and whether certain characteristics predicted initial levels and/or the trajectories of these parameters. Patients (n=396) were enrolled prior to surgery and completed monthly assessments for six months following surgery. The General Sleep Disturbance Scale was used to assess sleep disturbance and DS. Using hierarchical linear modeling, demographic, clinical, symptom, and psychosocial adjustment characteristics were evaluated as predictors of initial levels and trajectories of sleep disturbance and DS. All seven General Sleep Disturbance Scale scores were above the cutoff for clinically meaningful levels of sleep disturbance. Lower performance status; higher comorbidity, attentional fatigue, and physical fatigue; and more severe hot flashes predicted higher preoperative levels of sleep disturbance. Higher levels of education predicted higher sleep disturbance scores over time. Higher levels of depressive symptoms predicted higher preoperative levels of sleep disturbance, which declined over time. Lower performance status; higher body mass index; higher fear of future diagnostic tests; not having had sentinel lymph node biopsy; having had an axillary lymph node dissection; and higher depression, physical fatigue, and attentional fatigue predicted higher DS prior to surgery. Higher levels of education, not working for pay, and not having undergone neo-adjuvant chemotherapy predicted higher DS scores over time. Sleep disturbance is a persistent problem for patients with breast cancer. The effects of interventions that can address modifiable risk factors need to be evaluated.

In patients with severe aortic stenosis (AS) at intermediate surgical risk, treatment with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) results in similar 2-year survival. The effect of TAVR vs SAVR on health status in patients at intermediate surgical risk is unknown. To compare health-related quality of life among intermediate-risk patients with severe AS treated with either TAVR or SAVR. Between December 2011 and November 2013, 2032 intermediate-risk patients with severe AS were randomized to TAVR with the Sapien XT valve or SAVR in the Placement of Aortic Transcatheter Valve 2 Trial and were followed up for 2 years. Data analysis was conducted between March 1, 2016, to April 30, 2017. Health status was assessed at baseline, 1 month, 1 year, and 2 years using the Kansas City Cardiomyopathy Questionnaire (KCCQ) (23 items covering physical function, social function, symptoms, self-efficacy and knowledge, and quality of life on a 0- to 100-point scale; higher scores indicate better quality of life), Medical Outcomes Study Short Form-36 (36 items covering 8 dimensions of health status as well as physical and mental summary scores; higher scores represent better health status), and EuroQOL-5D (assesses 5 dimensions of general health on a 3-level scale, with utility scores ranging from 0 [death] to 1 [ideal health]). Analysis of covariance was used to examine changes in health status over time, adjusting for baseline status. Of the 2032 randomized patients, baseline health status was available for 1833 individuals (950 TAVR, 883 SAVR) who formed the primary analytic cohort. A total of 1006 (54.9%) of the population were men; mean (SD) age was 81.4 (6.8) years. Over 2 years, both TAVR and SAVR were associated with significant improvements in both disease specific (16-22 points on the KCCQ-OS scale) and generic health status (3.9-5.1 points on the SF-36 physical summary scale). At 1 month, TAVR was associated with better health status than SAVR, but this difference was restricted to patients treated via transfemoral access (mean difference in the KCCQ overall summary [KCCQ-OS] score, 14.1 points; 95% CI, 11.7 to 16.4; P < .01) and was not seen in patients treated via transthoracic access (mean difference in KCCQ-OS, 3.5 points; 95% CI, -1.4 to 8.4; P < .01 for interaction). There were no significant differences between TAVR and SAVR in any health status measures at 1 or 2 years. Among intermediate-risk patients with severe AS, health status improved significantly with both TAVR and SAVR through 2 years of follow up. Early health status improvement was greater with TAVR, but only among patients treated via transfemoral access. Longer term follow-up is needed to assess the durability of quality-of-life improvement with TAVR vs SAVR in this population. clinicaltrials.gov Identifier: NCT01314313.

Self-esteem is implied as a factor in the development of eating disorders. In adolescence peers have an increasing influence. Support for the role of self-esteem in eating disorders is ambiguous and little is known about the influence of social status as judged by others. The present study investigates whether self-esteem and peer status in early adolescence are associated with eating pathology in young adulthood. This study is part of TRAILS, a longitudinal cohort study on mental health and social development from preadolescence into adulthood. At age 11, participants completed the Self-Perception Profile for Children, assessing global self-esteem and self-perceptions regarding social acceptance, physical appearance, and academic competence. At age 13, peer status among classmates was assessed regarding likeability, physical attractiveness, academic performance, and popularity in a subsample of 1,007 participants. The Eating Disorder Diagnostic Scale was administered at age 22. The present study included peer-nominated participants with completed measures of self-perception at age 11 and eating pathology at age 22 (N = 732; 57.8% female). In a combined model, self-perceived physical attractiveness at age 11 and peer popularity at age 13 were inversely correlated with eating pathology at 22 years, while likeability by peers at age 13 was positively related to eating pathology. Both self-perceptions and peer status in early adolescence are significant predictors of eating pathology in young adults. Specific measures of self-esteem and peer-perceived status may be more relevant to the prediction of eating pathology than a global measure of self-esteem. © 2018 The Authors International Journal of Eating Disorders Published by Wiley Periodicals, Inc.

To evaluate the impacts of education level and employment status on health-related quality of life (HRQoL) in multiple sclerosis patients. This study included 100 multiple sclerosis patients treated at the Department of Neurology, Clinical Center of the University of Sarajevo. Inclusion criteria were the Expanded Disability Status Scale (EDSS) score between 1.0 and 6.5, age between 18 and 65 years, stable disease on enrollment. Quality of life (QoL) was evaluated by the Multiple Sclerosis Quality of Life-54 questionnaire (MSQoL-54). Mann-Whitney and Kruskal-Wallis test were used for comparisons. Linear regression analyses were performed to evaluate prediction value of educational level and employment status in predicting MSQOL-54 physical and mental composite scores. Full employment status had positive impact on physical health (54.85 vs. 37.90; p les than 0.001) and mental health (59.55 vs. 45.90; p les than 0.001) composite scores. Employment status retained its independent predictability for both physical (r(2)=0.105) and mental (r(2)=0.076) composite scores in linear regression analysis. Patients with college degree had slightly higher median value of physical (49.36 vs. 45.30) and mental health composite score (66.74 vs. 55.62) comparing to others, without statistically significant difference. Employment proved to be an important factor in predicting quality of life in multiple sclerosis patients. Higher education level may determine better QOL but without significant predictive value. Sustained employment and development of vocational rehabilitation programs for MS patients living in the country with high unemployment level is an important factor in improving both physical and mental health outcomes in MS patients.

Biological, psychological and social factors may interact with the mental health status of Graves' disease (GD) patients before and after antithyroid drug (ATD) treatment. Our aim was to quantify the impact of supportive and risk factors after recovery from GD which may enhance cure rates. 300 patients were recruited for a 6-year prospective cohort study. Before and after treatment, we assessed the impact of biopsychosocial factors on the success of ATD treatment and mental health using the Symptom Checklist 90, the Eysenck Personality Questionnaire, the Life Event Scale, Simplified Coping Styles and the Perceived Social Support Scale. The patients routinely received ATD at least over 18 months. End-point was defined as cured (at least 2 years without a relapse after the withdrawal of ATD), otherwise as not cured. Regression analysis explained 80.5% of the influences affecting mental health. The odds ratios (OR) revealed positive coping styles (OR: 2.90, 95% CI, 1.09-7.68), negative events (OR: 1.04, 95% CI, 1.01-1.07) and social support (OR: 5.10, 95% CI, 2.77-9.40) as protective factors, predicting a cure for GD patients. These variables explained 61.7% of the influences leading to a cure or no cure. Large thyroid volume was a risk factor, predicting failure (OR: 0.865, 95% CI, 0.83-0.90, P<0.000). Enhancing positive coping strategies and social support is important to improve mental health in GD patients, to avoid compromising work-related performance and endangering a patient's social status. © J.

AIMS (i) To describe the progression of the cardinal features of Parkinson's disease (PD); (ii) to investigate whether baseline PD subtypes explain disease progression; and (iii) to quantify the symptomatic and disease-modifying effects of anti-parkinsonian treatments. METHODS Data were available for 795 PD subjects, initially untreated, followed for up to 8 years. Cardinal features [tremor, rigidity, bradykinesia, and postural instability and gait disorder (PIGD)] were derived from the total unified Parkinson's disease rating scale (total UPDRS), cognitive status from the mini-mental status exam score (MMSE) and depression status from the Hamilton depression scale (HAM-D). Analysis was performed using a nonlinear mixed effects approach with an asymptotic model for natural disease progression. Treatment effects (i.e. symptomatic and disease modifying) were evaluated by describing changes in the natural history model parameters. RESULTS Tremor progressed more slowly (half-time of 3.9 years) than all other motor features (half-time 2–3 years). The MMSE progression was negligible, while HAM-D progressed with a half-time of 5 years. Levodopa had marked symptomatic effects on all features, but low potency for effect on PIGD (ED50 of 1237 mg day−1 compared with 7–24 mg day−1 for other motor and nonmotor features). Other anti-parkinsonian treatments had much smaller symptomatic effects. All treatments had disease-modifying effects on the cardinal features of PD. Baseline PD subtypes only explained small differences in disease progression. CONCLUSIONS This analysis indicates that tremor progresses more slowly than other cardinal features and that PIGD is less treatment responsive in early PD patients. There was no evidence of baseline PD subtypes as a clinically useful predictor of disease progression rate. Anti-parkinsonian treatments have symptomatic and disease-modifying effects on all major features of PD. PMID:22283961

Most voice self-rating tools are disease-specific measures and are not suitable for use with healthy voice users. There is a need for a tool that is sensitive to the subtleties of a singer's voice and to perceived physical changes in the singing voice mechanism as a function of load. The aim of this study was to devise and validate a scale to assess singer's perceptions of the current status of their singing voice. Ninety-five vocal health descriptors were collected from focus group interviews of singers. These were reviewed by 25 currently performing music theater (MT) singers. Based on a consensus technique, the number of descriptors was decreased to 42 items. These were administered to a sample of 284 professional MT singers using an online survey to evaluate their perception of current singing voice status. Principal component analysis identified two subsets of items. Rasch analysis was used to evaluate and refine these sets of items to form two 10-item subscales. Both subscales demonstrated good overall fit to the Rasch model, no differential item functioning by sex or age, and good internal consistency reliability. The two subscales were strongly correlated and subsequent Rasch analysis supported their combination to form a single 20-item scale with good psychometric properties. The Evaluation of the Ability to Sing Easily (EASE) is a concise clinical tool to assess singer's perceptions of the current status of their singing voice with good measurement properties. EASE may prove a useful tool to measure changes in the singing voice as indicators of the effect of vocal load. Furthermore, it may offer a valuable means for the prediction or screening of singers "at risk" of developing voice disorders. Copyright © 2013 The Voice Foundation. All rights reserved.

Previous studies indicate that self-esteem is lower among adolescents of low socio-economic status and is associated with a number of intrapersonal, interpersonal and socio-cultural factors. Evidence on the mechanisms by which these factors contribute to the connection between socio-economic status and developing self-esteem is incomplete, however. The purpose of this cross-sectional study is to assess whether personality, mental health and social support contribute to the relationship between socio-economic status and self-esteem. A sample of 3694 elementary-school students from Slovakia (mean age = 14.3 years, 49% boys) filled out the Rosenberg Self-esteem Scale, the Family Affluence Scale, the Ten-Item Personality Inventory, the 12-item General Health Questionnaire and the Perceived Social Support Scale. Hierarchical linear regression showed family affluence, personality dimensions of extroversion, emotional stability and openness to experience, as well as mental health subscales and social support from family and significant others to be associated with self-esteem. Results indicate that personality dimensions and mental health subscales contribute to the association between family affluence and self-esteem. The contribution of personality and mental problems in the relation between socio-economic status and self-esteem may have important implications for the design of promotional programs aimed at enhancing self-esteem.
