Relationship between sleep problems and health-related quality of life among pediatric liver transplant recipients.  

PubMed

Among adult liver transplant recipients (LTRs), sleep disturbances and fatigue are common. Sleep problems following pediatric liver transplantation may contribute to daytime fatigue and lower health-related quality of life (HRQOL). The aim of this cross-sectional study was to determine the impact of sleep problems on the HRQOL of pediatric LTRs using validated measures. Participants included 47 LTRs. Mean age of the LTRs was 10.9 ± 4.6 years, and mean time since transplantation was 6.2 ± 3.9 years. The primary indication for transplantation was biliary atresia (51%). According to parent reports, pediatric transplant recipients had symptoms of sleep-disordered breathing, excessive daytime sleepiness, daytime behavior problems, and restless legs; 40.4% of parents and 43.8% of children reported significantly lower total HRQOL for the recipients. Age, time since transplantation, and health status were not significantly related to the quality of life. Hierarchical regression analyses revealed that the sleep-disordered breathing subscale of the Pediatric Sleep Questionnaire accounted for significant variance in parent-proxy reports on the Pediatric Quality of Life (PedsQL) summary scales measuring children's psychosocial health (R(2) = 0.36, P < 0.001), physical health (R(2) = 0.19, P = 0.004), and total HRQOL (R(2) = 0.35, P < 0.001). Also, the sleep-disordered breathing subscale accounted for significant variance in the child self-reported school functioning scale (R(2) = 0.18, P = 0.03). Clinically significant sleep problems were more common among children with low total HRQOL. In conclusion, sleep problems were common in this cohort of pediatric LTRs and predicted significant variance in HRQOL. Prospective larger scale studies are needed to assess factors that contribute to sleep difficulties and low HRQOL in this population. The detection and treatment of significant sleep problems may benefit the HRQOL of pediatric LTRs. PMID:22344942

Health-related quality of life in patients with diabetic foot problems in Malaysia.  

PubMed

This study aimed to evaluate the impact of foot problems on health-related quality of life (HRQoL) in patients with diabetes in Malaysia. Short-Form 36 (SF-36) questionnaire was used to assess the HRQoL of 140 diabetic patients with foot problems attending outpatient diabetic foot clinic in a tertiary hospital, University Malaya Medical Centre. Their HRQoL were compared with 134 diabetic patients without foot problems attending the same clinic. The median score of all the eight SF-36 domains differed significantly between the two groups, where patients with foot problems having statistically significant lower scores. The two domains that were most severely compromised were components of the physical health: Physical Functioning and Role Physical domains. The SF-36 scale scores in diabetic patients with foot problems were also lower than those of the SF-36 norms for the Malaysian population. In conclusion, the results showed that diabetic foot problems negatively affect the patients' HRQoL in both physical and mental health aspects based on the SF-36. PMID:22111447

Trial of a negative ion generator device in remediating problems related to indoor air quality  

SciTech Connect

It has been suggested that supplementation of indoor air with negative ions can improve air quality. This study examined the effects of a negative ion-generator device on air contaminants and symptom reporting in two office buildings. Separate sets of functional and nonfunctional negative ion generators were monitored using a double blind, crossover design involving two 5-week exposure periods. There were no detectable direct or residual effects of negative ion generator use on air ion levels, airborn particulates, carbon dioxide levels, or symptom reporting. Symptom reporting declined at both sites initially and appeared to be consistent with placebo effect. Job dissatisfaction was an apparent contributor to symptom reporting, with a magnitude comparable to presumed effects of air quality. Further testing of such devices is needed before they should be considered for office air quality problems.

An asthma-related quality of life instrument is unable to identify asthmatic children with major psychosocial problems.  

PubMed

Evidence shows that psychosocial problems among children and adolescents with asthma interfere with adherence to treatment and therefore need attention in asthma care. It is unknown whether the already frequently implemented asthma-related quality of life (QoL) instruments reflect psychosocial problems in children with asthma. The aim of this study was to assess the relationship between asthma-related QoL and psychosocial problems and to determine whether an asthma-related QoL instrument is able to identify those children and adolescents with asthma with major psychosocial problems. In a multicenter study psychosocial problems (Strengths and Difficulties Questionnaire) and asthma-related QoL (Pediatric Asthma (Caregivers) Quality of Life Questionnaire) were obtained in children and adolescents with asthma aged 6-16 years and their caregivers. A total of 339 children and adolescents (response rate 95%) from four pediatric outpatient clinics in the Netherlands with doctor-diagnosed asthma participated. Of the caregivers, 43% reported major or minor psychosocial problems of their child or adolescent which is two times more than in the reference group, whereas the percentage of adolescents reporting psychosocial problems was comparable to a reference population. Adolescents and caregivers reported few impairments in asthma-related QoL (median score between 6.2 and 7.0). However, an optimal asthma-related QoL did not rule out major psychosocial problems: 10% of the adolescents with an optimal asthma-related QoL score reported major psychosocial problems. And in one out of seven children with an optimal caregiver's asthma-related QoL score, major psychosocial problems were reported. The prevalence of psychosocial problems in children and adolescents with asthma is considerable. Assessment of asthma-related QoL alone is insufficient to identify those children with major psychosocial problems. We recommend the implementation of psychosocial screening, besides assessment of asthma-related QoL, in routine pediatric asthma care, to improve asthma management. PMID:20640442

The proxy problem anatomized: child-parent disagreement in health related quality of life reports of chronically ill adolescents  

PubMed Central

Background Discrepancy between self-reports and parent-proxy reports of adolescent health-related quality of life (HRQoL) has been repeatedly acknowledged in the literature as the proxy problem. However, little is known about the extent and direction of this discrepancy. The purpose of this study is to explore to what extent and in what direction HRQoL self-reports of adolescents with chronic conditions and those of their parents differ. Methods A cross-sectional survey was conducted among adolescents suffering from chronic conditions and their parents. Socio-demographic and disease-related characteristics were collected and information about consequences of the chronic condition was assessed. HRQoL was measured with KIDSCREEN-10 and DISABKIDS condition generic measure (DCGM-10). Agreement was analysed through defining a threshold of agreement based on half of the standard deviation of the HRQoL score with the highest variance. Agreement occurred if the difference between adolescent and parent scores was less than or equal to half of the standard deviation. Intra-class correlation coefficients and Bland-Altman plots were also computed. The characteristics associated with direction of disagreement were statistically tested with one-way ANOVA and Chi-square tests. Results 584 paired HRQoL scores were obtained. Ratings from both adolescents and parents were high, compared to European norm data. Differences between adolescents and parents were statistically significant, yet relatively small. Disagreement existed in both directions: in 24.5% (KIDSCREEN-10) and 16.8% (DCGM-10) of the cases adolescents rated their HRQoL lower than did their parent, while in 32.2% (KIDSCREEN-10) and 31.7% (DCGM-10) of the cases the opposite was true. Adolescent's age, educational level and type of education, parent's educational level, number of hospital admissions and several other disease-related factors influenced direction of disagreement. Conclusions In a reasonable proportion of cases the adolescent and parent agreed on the adolescent's HRQoL (43-51% of the cases) and most disagreement tended to be minor. Thus, the proxy problem may be smaller than presented in the literature and its extent may differ per population. As adolescents are expected to become partners in their own health care, it is recommended to focus on adolescents' own perceptions of HRQoL.

Validation of the Korean translation of obesity-related problems scale assessing the quality of life in obese Korean  

PubMed Central

Purpose The objective of this study was to translate the obesity-related problems (OP) scale for Koreans and to validate it for use in Korean populations. Methods Translation and back-translation of the OP scale was performed and a pilot test was conducted. Following this, patients who had received treatment at the Obesity Center of Inha University Hospital were selected for participation in the field test. Cronbach's alpha (?) was used for assessment of the internal consistency of the OP scale. Spearman's correlation coefficients were used to assess the concurrent validity between the OP scale, the EuroQoL-5D (EQ-5D), and the Beck depression inventory (BDI) scale. One-way analysis of variance and t-test were used to assess the factors associated with the OP scale. Results A total of 67 individuals participated in the field study. The standardized Cronbach's ? of the OP was 0.913. A significant negative correlation was observed between the OP scale and the EQ-5D and a positive correlation was observed between the OP scale and the BDI (the correlation coefficient with EQ-5D = -0.316, and the BDI = 0.305, P < 0.05). Conclusion The results of this study prove that the Korean version of the OP has been translated and adapted correctly in order to meet the standard of its use.

Health-related quality of life in adolescent chronotypes--a model for the effects of sleep problems, sleep-related cognitions, and self-efficacy.  

PubMed

In adolescence, the circadian preference shifts toward eveningness orientation. Eveningness seems to be negatively correlated with quality of life. The present study investigates influencing factors of this association and proposes a model for the mediating effects of sleep, sleep-related cognitions, and self-efficacy according to chronotype. The sample comprised N?=?280 adolescents (172 girls) aged 14-16 yrs (mean?=?15.19, SD?=?.76). Circadian preference, health-related quality of life (HRQoL), sleep disturbances, sleep-related dysfunctional cognitions, and general perceived self-efficacy were assessed online. Morning-orientated adolescents reported significantly higher HRQoL and less insomnia symptoms compared with evening-oriented chronotypes. In the total sample, insomnia symptoms mediated the relationship of chronotype and HRQoL. The strongest predictor of HRQoL in evening types was the degree of sleep-related dysfunctional cognitions. HRQoL in morning types was most strongly predicted by general self-efficacy, i.e., the global confidence in coping abilities. The findings support a negative relationship of eveningness and HRQoL in adolescents. Insomnia symptoms were identified to be mediating factors in this relationship. The influence of the mediating factors on HRQoL differed between morning and evening types. The model provides implications of how to enhance HRQoL in adolescents according to their circadian preference. PMID:23131114

"They silently live in terror…" why sleep problems and night-time related quality-of-life are missed in children with a fetal alcohol spectrum disorder.  

PubMed

Children and adolescents with a Fetal Alcohol Spectrum Disorder (FASD) are at high-risk for developing sleep problems (SPs) triggering daytime behavioral co-morbidities such as inattention, hyperactivity, and cognitive and emotional impairments. However, symptoms of sleep deprivation are solely associated with typical daytime diagnosis, such as attention deficit hyperactivity disorder (ADHD) and treated with psychotropic medications. To understand how and why SPs are missed, we conducted qualitative interviews (QIs) with six parents and seven health care professionals (HCPs), and performed comprehensive clinical sleep assessments (CCSAs) in 27 patients together with their caregivers referred to our clinic for unresolved SPs. We used narrative schema and therapeutic emplotment in conjunction with analyzes of medical records to appropriately diagnose SPs and develop treatment strategies. The research was conducted at British Columbia Children's Hospital in Vancouver (Canada) between 2008 and 2011. In the QIs, parents and HCPs exhibited awareness of the significance of SPs and the effects of an SP on the daytime behaviors of the child and the associated burdens on the parents. HCPs' systemic inattention to the sequelae of SPs and the affected family's wellbeing appears due to an insufficient understanding of the various factors that contribute to nighttime SPs and their daytime sequelae. In the CCSAs, we found that the diagnostic recognition of chronic SPs in children and adolescents was impaired by the exclusive focus on daytime presentations. Daytime behavioral and emotional problems were targets of pharmacological treatment rather than the underlying SP. Consequently, SPs were also targeted with medications, without investigating the underlying problem. Our study highlights deficits in the diagnostic recognition of chronic SPs among children with chronic neurodevelopmental disorders/disabilities and proposes a clinical practice strategy, based on therapeutic emplotment that incorporates patients and parents' contributions in recognizing SPs and related sequelae in designing appropriate treatment and care.

The Burnside problem and related topics  

NASA Astrophysics Data System (ADS)

This paper gives a survey of results related to the famous Burnside problem on periodic groups. A negative solution of this problem was first published in joint papers of P.S. Novikov and the author in 1968. The theory of transformations of words in free periodic groups that was created in these papers and its various modifications give a very productive approach to the investigation of hard problems in group theory. In 1950 the Burnside problem gave rise to another problem on finite periodic groups, formulated by Magnus and called by him the restricted Burnside problem. Here it is called the Burnside-Magnus problem. In the Burnside problem the question of local finiteness of periodic groups of a given exponent was posed, but the Burnside-Magnus problem is the question of the existence of a maximal finite periodic group R(m,n) of a fixed period n with a given number m of generators. These problems complement each other. The publication in a joint paper by the author and Razborov in 1987 of the first effective proof of the well-known result of Kostrikin on the existence of a maximal group R(m,n) for any prime n, together with an indication of primitive recursive upper bounds for the orders of these groups, stimulated investigations of the Burnside-Magnus problem as well. Very soon other effective proofs appeared, and then Zel'manov extended Kostrikin's result to the case when n is any power of a prime number. These results are discussed in the last section of this paper. Bibliography: 105 titles.

Sleep-related problems in neurologic diseases.  

PubMed

There is a strong association between sleep-related problems and neurologic diseases. Neurologic diseases of the CNS can directly cause sleep problems when sleep-wake mechanisms associated with the ascending reticular activating system are involved. The major sleep disorders associated with neurologic problems are outlined in the International Classification of Sleep Disorders, 2nd edition, as hypersomnias of central origin, sleep-related breathing disorders, the insomnias, circadian rhythm sleep disorders, sleep-related movement disorders, parasomnias, and sleep-related epilepsy. In a patient with CNS disease and excessive sleepiness, sleep-related breathing disorders should be a first concern, given the known association between obstructive sleep apnea (OSA) and cerebrovascular disease and the potential confounding effects that OSA might have on an otherwise compromised ischemic CNS penumbra. A basic knowledge of the anatomy and physiology of the sleep-wake mechanisms provides a rationale for pharmacologic intervention. Nonpharmacologic treatments are also important, especially when sleep-related breathing disorders are a concern. In addition, as patients with neurologic diseases are often prone to the adverse effects of many medications, the specific treatment regimen for any given individual should always include good sleep hygiene practices that use cognitive behavioral therapy.

Impact of Pharmaceutical Care interventions in the identification and resolution of drug-related problems and on quality of life in a group of elderly outpatients in Ribeir?o Preto (SP), Brazil  

PubMed Central

Objective To evaluate the impact of a Pharmaceutical Care service in the identification and resolution of drug-related problems (DRPs) and in quality of life (QoL) of a group of elderly outpatients with chronic health conditions. Methods 30 outpatients (aged 60–75-years old) were followed between August 2003 and July 2004 at a primary health care unit in Ribeirão Preto (SP), Brazil. Patients were scheduled monthly to meet with the researcher, who provided Pharmaceutical Care service (the intervention). Through Pharmaceutical Care, the pharmacist worked with the patient and other care providers to improve outcomes of drug therapy through focused education, care planning, and monitoring. Intervention outcomes were the number of DRPs prevented or resolved, and the impact on QoL. The Short Form-36 health survey was used to measure changes in QoL. Results The mean age of patients was 66 ± 5 years, 21 of whom had low literacy. During the study, 92 DRP were identified, 3.0 ± 1.5 problems per patient. By the end of the study, the interventions solved 69% of actual DRP and prevented 78.5% potential DRP. In addition, QoL showed improvement in 22 patients after DRP resolution or prevention. Conclusion Despite the limitations in this study that may affect generalizability of the results, this study demonstrates that humanistic and behavioral interventions based on the Pharmaceutical Care model were capable in reducing DRPs, and improve QoL in patients.

Operational Water Quality Management: Problem Context and Evaluation of a Model for River Quality  

NASA Astrophysics Data System (ADS)

In river basins where water is used intensively and by many activities and facilities, the essential questions of water quality management are changing from being issues of planning alone to being problems of operational decision making. In the past 10 years in the United Kingdom, for example, the technology, economics, legislation, and institutional structure of management have all changed substantially. Together these changes have overturned the traditional assumptions made about the nature of managing river water quality. This paper discusses the foundations for a case study in operational water quality management. The basis of the case study is a dynamic model for stream discharge and quality covering a 54-km stretch of the Bedford Ouse River in England. The model describes interactions among biochemical oxygen demand, dissolved oxygen, ammonium N, nitrate N, and chlorophyll a concentrations at various points along the river; preliminary identification results are presented using daily time series data for the whole of 1974. The behavior of the river, which relates the effects of a major upstream discharger to a downstream abstractor, is dominated by the dynamics of algal population growth and mortality. In addition to the presentation of these results the paper sets out the technical, economic, and policy questions central to the practical feasibility and potential of operational water quality management. This includes questions in quantifying the stochastic, dynamic aspects of river basin management, the development of improved operating strategies, and the development of operational decision support systems.

Relative locality and the soccer ball problem  

SciTech Connect

We consider the behavior of macroscopic bodies within the framework of relative locality [G. Amelino-Camelia, L. Freidel, J. Kowalski-Glikman, and L. Smolin, arXiv:1101.0931]. This is a recent proposal for Planck scale modifications of the relativistic dynamics of particles which are described as arising from deformations in the geometry of momentum space. We consider and resolve a common objection against such proposals, which is that, even if the corrections are small for elementary particles in current experiments, they are huge when applied to composite systems such as soccer balls, planets, and stars, with energies E{sub macro} much larger than M{sub P}. We show that this soccer ball problem does not arise within the framework of relative locality because the nonlinear effects for the dynamics of a composite system with N elementary particles appear at most of order E{sub macro}/N{center_dot}M{sub P}.

Effects of problem difficulty and reinforcer quality on time allocated to concurrent arithmetic problems.  

PubMed Central

Students with learning difficulties participated in two studies that analyzed the effects of problem difficulty and reinforcer quality upon time allocated to two sets of arithmetic problems reinforced according to a concurrent variable-interval 30-s variable-interval 120-s schedule. In Study 1, high- and low-difficulty arithmetic problems were systematically combined with rich and lean concurrent schedules (nickels used as reinforcers) across conditions using a single-subject design. The pairing of the high-difficulty problems with the richer schedule failed to offset time allocated to that alternative. Study 2 investigated the interactive effects of problem difficulty and reinforcer quality (nickels vs. program money) upon time allocation to arithmetic problems maintained by the concurrent schedules of reinforcement. Unlike problem difficulty, the pairing of the lesser quality reinforcer (program money) with the richer schedule reduced the time allocated to that alternative. The magnitude of this effect was greatest when combined with the low-difficulty problems. These studies have important implications for a matching law analysis of asymmetrical reinforcement variables that influence time allocation.

Analysis of quality factors in the sorting problem  

SciTech Connect

The problem of defining an efficient procedure to sort the magnets in a circular accelerator is considered. Using a simplified model of the LHC, we analyze the effects of random errors on the dynamic aperture. Different quality factors are proposed to measure the performances of a given lattice. These quantities are based on the analytical tools of nonlinear maps and normal forms. The correlation between quality factors and dynamic aperture is analyzed and a sorting strategy, based on these indicators of nonlinearity, is proposed. A comparison of the results with a sorting method based on local compensation is given.

[Health-related problems in adopted children].  

PubMed

International research shows that the standard of health among children adopted from abroad, especially those adopted by single parents, is not as good as that of other children. Danish studies indicate similar problems. The causes could be several, such as poor development in the embryonic and fetal stages, low birth weight, starvation, neglect, infections, and the lack of the natural bonds between mother and child. Surveys indicate that many adoptive parents, single parents in particular, receive children with health problems. There is no Danish research available, but it is important to be aware of these issues in order for both adoptees and adoptants to receive the most support. PMID:17059801

The Working Party on Culture Media (WPCM) of the International Union of Microbiological Societies (IUMS) has promoted and facilitated the development of methods for quality control of culture media used for the detection and enumeration of food-borne microorganisms since the early 1980s. While progress has been made in establishing protocols to test for productivity and selectivity of media, problems associated with the influence of food constituents and background microflora, as well as the presence of sublethally injured cells in test foods, are yet to be fully addressed before optimum methods for assessing the quality of media can be defined. However, for various reasons, the development of standardised procedures which account for the influence of food constituents or state of debilitation of target microorganisms may not be practical or even desirable.

Water and related problems in coal-mine areas of Alabama  

USGS Publications Warehouse

Water-resource problems or potential problems in Alabama resulting from surface and subsurface coal mining include erosion and sedimentation, flooding, diversion of drainage, decline in water level, land subsidence, and the degradation of water quality. The degradation of water quality is the most serious and widespread coal-mine related problem in Alabama. The chemical quality of water in numerous streams draining coal-mine areas has been altered drastically. The pH of water draining from mined areas commonly ranges from 2.1 to 5.0, generally has high sulfate and dissolved solids concentrations, is hard to very hard, and may contain objectionable amounts of iron. The detrimental quality of water in some streams may persist for decades after mining has ceased. Without proper safeguards, additional mining may cause a significant deterioration in the quality of water in major streams where the more mineralized mine waters are now diluted. (Woodard-USGS)

Controlling alcohol-related global health problems.  

PubMed

Alcohol's adverse public health impact includes disease, injury, violence, disability, social problems, psychiatric illness, drunk driving, drug use, unsafe sex, and premature death. Furthermore, alcohol is a confirmed human carcinogen. The International Agency for Research on Cancer concluded that alcohol causes cancer of the oral cavity, pharynx, larynx, esophagus, liver, colon-rectum, and breast. World Cancer Research Fund/American Institute for Cancer Research concluded that the evidence justifies recommending avoidance of consuming any alcohol, even in small quantities. Despite being responsible for 3.8% of global deaths (2,255,000 deaths) and 4.6% of global disability-adjusted life years in 2004, alcohol consumption is increasing rapidly in China and Asia. Contrary to the World Health Assembly's call for global control action, Hong Kong has reduced wine and beer taxes to zero since 2008. An International Framework Convention on Alcohol Control is urgently needed. Increasing alcohol taxation and banning alcohol advertisement and promotion are among the most effective policies.

Management of Amiodarone-Related Thyroid Problems  

PubMed Central

Amiodarone is a highly effective and well-established antiarrrhythmic drug. It can be used to treat supraventricular and ventricular tachyarrhythmias and has the added advantage of being well tolerated in patients with impaired left ventricular systolic function with a low incidence of arrhythmic events, such as torsades de pointes. However, owing to its marked lipid affinity, it is highly concentrated in tissues and is linked to a number of adverse effects, including thyroid dysfunction. Amiodarone can lead to both hypothyroidism (amiodarone-induced hypothyroidism) and less commonly hyperthyroidism (amiodarone-induced thyrotoxicosis) and relates to high iodine content within the molecule as well as to several unique intrinsic properties of amiodarone. Dronedarone is a recently approved antiarrhythmic drug. It is structurally very similar to amiodarone, however the iodine moiety, present with amiodarone has been removed and replaced with a methylsulfonamide group to reduce fat solubility and adverse effects. We present an overview of the effects of amiodarone on thyroid function and the treatment options available, as well as a brief insight into dronedarone and its potential as an alternative to amiodarone.

Oral Health-related Quality of Life  

PubMed Central

Despite its relatively recent emergence over the past few decades, oral health-related quality of life (OHRQoL) has important implications for the clinical practice of dentistry and dental research. OHRQoL is a multidimensional construct that includes a subjective evaluation of the individual’s oral health, functional well-being, emotional well-being, expectations and satisfaction with care, and sense of self. It has wide-reaching applications in survey and clinical research. OHRQoL is an integral part of general health and well-being. In fact, it is recognized by the World Health Organization (WHO) as an important segment of the Global Oral Health Program (2003). This paper identifies the what, why, and how of OHRQoL and presents an oral health theoretical model. The relevance of OHRQoL for dental practitioners and patients in community-based dental practices is presented. Implications for health policy and related oral health disparities are also discussed. A supplemental Appendix contains a Medline and ProQuest literature search regarding OHRQoL research from 1990-2010 by discipline and research design (e.g., descriptive, longitudinal, clinical trial, etc.). The search identified 300 articles with a notable surge in OHRQoL research in pediatrics and orthodontics in recent years.

Differentiation of Attention-Related Problems in Childhood Absence Epilepsy  

PubMed Central

The current study examined the specific types of attention-related problems CAE children experience and the role of disease factors on the development of attention-related problems. Thirty-eight subjects with CAE and 46 healthy controls, ages 6 to 16 participated in the study. The Behavior Assessment System for Children (BASC) was completed by parents, and the Attention Problems and Hyperactivity subscales were used to characterize CAE children’s problems. Item analysis within the subscales revealed that CAE children demonstrated higher rates of hyperactive (overactivity and fidgetiness) and inattentive (forgetfulness and distractibility) problems, and required more supervision. Within CAE analyses revealed that those who were actively having seizures were more impatient and those with a longer duration of illness were less proficient in completing homework. Children with CAE are at risk for certain inattentive and hyperactive problems, which can differ depending on duration of illness and active seizure status.

The dramatic increases in rates of pediatric obesity has created a mounting need for psychologists and other mental health care providers to play a significant role in the assessment and treatment of youth with eating- and weight-related problems. Therefore, it is imperative for providers to be aware of the causes and consequences of eating- and weight-related problems and to be familiar with evidence-based assessment and intervention approaches. Currently, the most well-established intervention approaches are family-based behavioral treatments, and weight loss maintenance treatments with a socio-ecological focus are promising. This paper provides a comprehensive review of these topics and highlights the important roles that mental health care providers can have. Medical settings are often the patient’s first point of contact within the healthcare system, making mental health care providers in such settings uniquely suited to assess for a broad range of eating- and weight-related problems and associated comorbidities, to deliver relevant evidence-based interventions, and to make appropriate referrals. Moving forward, providers and researchers must work together to address key questions related to the nature of eating- and weight-related problems in youth and to achieve breakthroughs in the prevention and treatment of such problems in this vulnerable population.

The electric utility-industrial user partnership in solving power quality problems  

SciTech Connect

This paper summarizes various views on power quality among industrial end users and utility personnel. The issues raised include: the most salient power quality problems, their causes, and designing the most effective technical and organizational responses to these problems. Recent technological advancement has helped to precipitate power quality problems through the widespread influx of sophisticated electrical equipment that is sensitive to common power quality problems; particularly momentary loss of power and inadvertent noise that infiltrates into sensitive logic circuits. These problems have been exacerbated through the growing use of power electronics equipment which, although beneficial, can generate harmonic distortion and notching of the line voltage. Although these are not the only power quality problems, identifying and technically solving these emerging problems is an engineering challenge that can be met on a case by case basis.

Spectral methods for numerical relativity: The initial data problem  

NASA Astrophysics Data System (ADS)

The partial differential equations of numerical relativity have traditionally been solved using a finite difference (FD) approximation. The accuracy of a FD solution increases as a fixed power of resolution while the computational resources required for the solution increase as the resolution raised to the (space + time) dimensionality of the problem. Modest accuracy solutions to problems involving either the initial conditions or the evolution of a dynamical black hole spacetime tax the capabilities of the computers presently available for the task, while the resources required for modest accuracy binary black hole problems are beyond what is presently available. For problems with smooth solutions alternatives to the FD approximation exist that may make more efficient use of the available computational resources. Here we investigate one of these techniques: the pseudo-spectral collocation (PSC) approximation. To determine its effectiveness relative to FD methods in solving problems in numerical relativity we use PSC to solve several two-dimensional problems that have been previously studied by other researchers using FD methods, focusing particularly on the computational resources required as a function of the desired solution accuracy. We find that PSC methods applied to these problems can achieve close to the theoretical limit of exponential convergence with problem resolution, while the computational resources required continue to scale only as the resolution raised to the problem dimensionality. Correspondingly, for solutions of even modest accuracy we find that PSC is substantially more efficient, as measured by either execution time or memory required, than FD; furthermore, these savings increase rapidly with increasing accuracy. We also discuss less quantitative but no less tangible advantages that the PSC approximation holds over the FD approximation. In particular, the solution provided by PSC is an analytic function given everywhere on the computational domain, not just at fixed grid points. Consequently, no ad hoc interpolation operators are required to determine field values at intermediate points or to evaluate the approximate solution or its derivatives on the boundaries. Since the practice of numerical relativity by finite differencing has been, and continues to be, hampered by both high computational resource demands and the difficulty of formulating acceptable finite difference alternatives to the analytic boundary conditions, we argue that PSC should be further pursued as an alternative way of formulating the computational problem of finding numerical solutions to the field equations of general relativity.

GEE-WIS Anchored Problem Solving Using Real-Time Authentic Water Quality Data  

NASA Astrophysics Data System (ADS)

GEE-WIS scientific problem solving consists of observing, hypothesizing, synthesis, argument building and reasoning, in the context of analysis, representation, modeling and sense-making of real-time authentic water quality data. Geoscience Environmental Education - Web-accessible Instrumented Systems, or GEE-WIS, an NSF Geoscience Education grant, has established a set of companion websites that stream real-time data from two campus retention ponds for research and use in secondary and undergraduate water quality lessons. We have targeted scientific problem solving skills because of the nature of the GEE-WIS environment, but further because they are central to state and federal efforts to establish science education curriculum standards and are at the core of performance-based testing. We have used a design experiment process to create and test two Anchored Instruction scenario problems. Customization such as that done through a design process, is acknowledged to be a fundamental component of educational research from an ecological psychology perspective. Our efforts have shared core design elements with other NSF water quality projects. Our method involves the analysis of student written scenario responses for level of scientific problem solving using a qualitative scoring rubric designed from participation in a related NSF project, SCALE (Synergy Communities: Aggregating Learning about Education). Student solutions of GEE-WIS anchor problems from Fall 2001 and Spring 2002 will be summarized. Implications are drawn for those interested in making secondary and high education geoscience more realistic and more motivating for students through the use of real-time authentic data via Internet.

The relation of eating problems and amenorrhea in ballet dancers.  

PubMed

Exercise-induced amenorrhea has received considerable attention in the medical literature. The combination of exercise and low body weight is thought to exert synergistic effects in the pathogenesis of amenorrhea, while the role of dieting and eating problems, another possible causative mechanism, has not been examined. A sample of 55 adult dancers in national and regional classical ballet companies was studied; their mean age was 24.7 yr. Fifty-six percent of the dancers had delayed menarche (age 14 or later) and 19% of the sample were currently amenorrheic (5 months or longer). One-third of the dancers reported having had an eating problem (self-reported anorexia nervosa or bulimia). Amenorrhea and reported eating problems were significantly related: 50% of amenorrheics reported anorexia nervosa while 13% of the normals did. In addition, prolonged amenorrhea was significantly related to dieting (as measured by EAT-26 scales, a measure of dieting behavior). As expected, leanness and absolute weight also were related to prolonged amenorrhea. Amenorrhea in this sample of adult dancers was not related to current activity level or age at which training began. Thus, eating problems may be one factor in the pathogenesis of prolonged amenorrhea in certain athletic groups. PMID:3469489

Information needs related to teaching about air quality.  

PubMed

Translating knowledge of air quality into a form that can be understood by students and the general public is a major challenge for scientists, public officials, and teachers. Social science studies have shown that both educators and the general public are relatively uninformed about recent findings in environmental research. It is especially difficult to get students of today excited about environmental issues because environmental education has become institutionalized. Students believe they know about major environmental problems even when their knowledge is rudimentary or even wrong. One problem in getting public attention is the general level of hyperbole and hysteria common in most media. Thus, do we try to be even more shrill and apocalyptic than other advocates clamoring for public notice, or should we refuse to participate in this competition for attention?A model is presented to bring K-12 teachers, scientists, and students together to develop innovative, inquiry-based, active learning materials for environmental education. Curricular materials utilizing the discovery process can be created and tested in an iterative process that incorporates the results of current science research into highly effective teaching materials for schools. Following extensive evaluative procedures and review, exemplary materials are prepared for publication. This collaborative method also gives teachers and students a more realistic understanding of how science works by giving them access to active scientists and practical scientific experience.Finally, we argue that scientists need to reveal why they care about environmental issues. It is not enough to remain aloof and objective. If we are going to motivate students and the public to make changes in their lives, we need to make a convincing case for the importance of air quality and what it means in practical terms to our common environment.

The Drinking Problems Index: a measure to assess alcohol-related problems among older adults.  

PubMed

Research on problem drinking among older adults has been hampered by the lack of specialized instruments to assess drinking problems. In this paper, we examine the psychometric properties of a 17-item measure specifically designed to assess drinking problems in this population. The Drinking Problems Index (DPI) exhibits excellent psychometric properties, with an internal consistency reliability estimate of .94, a cross-temporal correlation over a 1-year interval of .66, and cross-sectional correlations with alcohol consumption at two points a year apart of .37 and .42. In addition, the construct validity of the DPI is supported by significant concurrent correlations indicating that persons who have more drinking-related problems experience more depression, have less self-confidence, and participate in fewer social activities. Consistent with the high internal consistency reliability estimate, a factor analysis confirmed that the measure is largely unifactorial. Overall, the findings suggest that the DPI is a reliable and valid instrument for assessing problems associated with drinking in surveys of older persons. PMID:1821293

Survey of travel-related problems in dogs.  

PubMed

The aim of this study was to quantitatively assess the kind of transport dogs undergo, the behaviours displayed during transport, the prevalence of travel-related problems in dogs and owners' interventions to solve these problems. A convenience sample of 907 dog owners completed a questionnaire containing 16 multiple-choice questions. All dogs had been transported by car at least once, but 4.7 per cent were no longer transported. 76.2 per cent of animals always responded positively to car transport, the rest showing or having shown problems (6.7 per cent always reacted negatively). Dogs were found to be more excited than inhibited during car transport. The vast majority (86.0 per cent) had become used to travelling by car as puppies; this made them less likely to develop problems (6.3 per cent v 24.1 per cent; ?(2)=19.886, P=0.000). If dogs were transported only to veterinary clinics, they were more prone to respond negatively to car transport (46.4 per cent v 22.7 per cent; ?(2)=7.245, P=0.007). For dogs reported as problematic (23.8 per cent of the sample), 96.3 per cent of the owners did not administer any treatments or other substances, 48.7 per cent did not seek any advice, and 40.4 per cent of them made attempts to solve the problem by themselves.

Quantifying Clinical Data Quality Using Relative Gold Standards  

PubMed Central

As the use of detailed clinical data expands for strategic planning, clinical quality measures, and research, the quality of the data contained in source systems, such as electronic medical records, becomes more critical. Methods to quantify and monitor clinical data quality in large operational databases involve a set of predefined data quality queries that attempt to detect data anomalies such as missing or unrealistic values based on meta-knowledge about a data domain. However, descriptive data elements, such as patient race, cannot be assessed using these methods. We present a novel approach leveraging existing intra-institutional databases with differing data quality for the same data element to quantify data quality for descriptive data. Using the concept of a relative gold standard, we show how this method can be used to assess data quality in enterprise clinical databases.

Sleep Characteristics, Sleep Problems, and Associations to Quality of Life among Psychotherapists  

PubMed Central

Sleep problems, especially insomnia, are a common complaint among adults. International studies have shown prevalence rates between 4.7 and 36.2% for sleep difficulties in general, whereas 13.1–28.1% report insomnia symptoms. Sleep problems are associated with lower social and academic performance and can have a severe impact on psychological and physical health. Psychotherapists are suppliers within the public health system. The goal of this study was to outline sleep characteristics, prevalence of sleep problems, insomnia, and associations of quality of life among psychotherapists. A total of 774 psychotherapists (74.7% women; mean age 46 years) participated in the study. Sleep characteristics, sleep problems, well-being, life satisfaction and workload, as well as specific job demands, were assessed via a questionnaire. Analyses revealed that more than 4.2% of the surveyed psychotherapists have difficulties falling asleep, 12.7% often wake up in the night, and 26.6% feel tired, and 3.4% think that their interrupted sleep affects work performance. About 44.1% of them suffer from symptoms of insomnia. Path models showed that insomnia is significantly related to well-being and life satisfaction.

Quality of Life in Persons with Intellectual Disabilities and Mental Health Problems: An Explorative Study  

PubMed Central

The field of intellectual disability (ID) is strongly influenced by the Quality of Life paradigm (QOL). We aimed at investigating whether or not the QOL paradigm also applies to clients with ID and cooccurring mental health problems. This paper aims at stimulating a debate on this topic, by investigating whether or not QOL domains are universal. Focus groups with natural and professional network members were organized to gather qualitative data, in order to answer two questions: (1) Are the QOL dimensions conceptualized in the model of Schalock et al. applicable for persons with ID and mental health problems? (2) What are indicators relating to the above-mentioned dimensions in relation to persons with ID and mental health problems? The results offer some proof for the assumption that the QOL construct seems to have universal properties. With regard to the second question, the study revealed that the natural and professional network members are challenged to look for the most appropriate support strategies, taking specific indicators of QOL into account. When aspects of empowerment and regulation are used in an integrated manner, the application of the QOL paradigm could lead to positive outcomes concerning self-determination, interdependence, social inclusion, and emotional development.

[Quality problems in quantitative determination of hemoglobin in blood].  

PubMed

Sources of errors in determination of hemoglobin were found out. The results were demonstrated to have comparison hemoglobin determination by hemiglobincyanide and hemichrome methods; this or that set of agents is of no significant advantage; to properly determine hemoglobin in the blood it is important to have calibration specimens and high quality control hemoglobin solutions; the equipment in use should be checked and calibrated; calibration hemiglobincyanide specimens produced at SPA "Renam". "Bak. preparations" and hemichrome specimens produced at JSC "Vector-Best" provide high precision of hemoglobin determination; the results of hemoglobin determination in control solutions obtained in autoanalyzers and manually, are comparable.

Negative affectivity and educational attainment as predictors of newlyweds' problem solving communication and marital quality.  

PubMed

This investigation examines the role of negative affectivity and educational attainment in newlywed couples' mutual problem solving and marital quality (i.e., personal commitment and divorce proneness). The vulnerability-stress-adaptation (VSA) model of marital development was used as a framework to explain the relationships between enduring vulnerabilities, adaptive processes, and marital quality. Dyadic analyses and tests of indirect effects were performed on data from 186 couples who had been married on average for 1.5 years. Spouses' negative affectivity and educational attainment were significantly associated with their own and their partner's mutual problem solving, personal commitment, and propensity to divorce. In addition, there was evidence supporting the assumption that the relationships between enduring vulnerabilities and marital quality can be explained, in part, by mutual problem solving for husbands. This study highlights the important role that enduring vulnerabilities have on mutual problem solving communication and marital quality. PMID:23472443

Prevention of alcohol-related problems. Introduction to a symposium.  

PubMed

Despite major biomedical advances, the most important health gains of this century have been due to preventive measures. Primary prevention includes: (a) health protection--the use of public direct regulatory activities (e.g. regulations regarding the sale and availability of alcohol, requirements for warning labels); (b) disease prevention--services directed to reducing the occurrence of specific identifiable disorders (e.g. Fetal Alcohol Syndrome) using strategies derived from risk factor research; and (c) health promotion--activities which foster positive behaviors and general good health practices. Although there is a measure of agreement that 'something must be done' to prevent alcohol problems, it is not quite so easy to find agreement on what is the best preventive approach, or even what the focus of prevention should be--problem drinkers, drinking habits or alcohol itself. To change attitudes and practices requires more than token nods towards alcohol education. More attention is now being given to psychologically and socially based prevention programs. The next three papers discuss behavioural approaches to prevention of alcohol-related problems. PMID:3678047

Less Drinking, Yet More Problems: Understanding African American Drinking and Related Problems.  

PubMed

Researchers have found that, compared to European Americans, African Americans report later initiation of drinking, lower rates of use, and lower levels of use across almost all age groups. Nevertheless, African Americans also have higher levels of alcohol problems than European Americans. After reviewing current data regarding these trends, we provide a theory to understand this apparent paradox as well as to understand variability in risk among African Americans. Certain factors appear to operate as both protective factors against heavy use and risk factors for negative consequences from use. For example, African American culture is characterized by norms against heavy alcohol use or intoxication, which protects against heavy use but also provides within-group social disapproval when use does occur. African Americans are more likely to encounter legal problems from drinking than European Americans, even at the same levels of consumption, perhaps thus resulting in reduced consumption but more problems from consumption. There appears to be one particular group of African Americans, low-income African American men, who are at the highest risk for alcoholism and related problems. We theorize that this effect is due to the complex interaction of residential discrimination, racism, age of drinking, and lack of available standard life reinforcers (e.g., stable employment and financial stability). Further empirical research will be needed to test our theories and otherwise move this important field forward. A focus on within-group variation in drinking patterns and problems is necessary. We suggest several new avenues of inquiry. (PsycINFO Database Record (c) 2013 APA, all rights reserved). PMID:23477449

Differential Susceptibility Effects: The Interaction of Negative Emotionality and Sibling Relationship Quality on Childhood Internalizing Problems and Social Skills  

PubMed Central

Whereas socialization influences in early childhood have been linked to children’s emerging internalizing problems and prosocial behavior, relatively few studies have examined how NE might moderate such associations in both advantageous and maladaptive ways. Furthermore, more research is needed to evaluate the impact of sibling relationships as an influential socialization influence on these child outcomes. In the current study we examined how NE might differentially moderate the associations between quality of relationships with siblings and both internalizing problems and social skills at school entry. NE moderated the effects of positive and destructive sibling relationship quality on child internalizing problems. Specifically, for boys high on NE, more positive sibling relationship quality predicted fewer internalizing problems, but more destructive sibling conflict predicted more internalizing problems. NE also moderated the effects of destructive sibling conflict on child social skills. For boys high on NE, destructive sibling conflict predicted fewer social skills. Boys high on NE appear to show greater susceptibility to the effects of sibling socialization on child outcomes, relative to boys low on NE. The implications of these interactions are discussed with respect to differential susceptibility theory.

The relative degree enhancement problem for MIMO nonlinear systems  

SciTech Connect

The authors present a result for linearizing a nonlinear MIMO system by employing partial feedback - feedback at all but one input-output channel such that the SISO feedback linearization problem is solvable at the remaining input-output channel. The partial feedback effectively enhances the relative degree at the open input-output channel provided the feedback functions are chosen to satisfy relative degree requirements. The method is useful for nonlinear systems that are not feedback linearizable in a MIMO sense. Several examples are presented to show how these feedback functions can be computed. This strategy can be combined with decentralized observers for a completely decentralized feedback linearization result for at least one input-output channel.

Resolving the Southern African Large Telescope's image quality problems  

NASA Astrophysics Data System (ADS)

Images obtained with the Southern African Large Telescope (SALT) during its commissioning phase in 2006 showed degradation due to a large focus gradient, astigmatism, and higher order optical aberrations. An extensive forensic investigation exonerated the primary mirror and the science instruments before pointing to the mechanical interface between the telescope and the spherical aberration corrector, the complex optical subassembly which corrects the spherical aberration introduced by the 11-m primary mirror. Having diagnosed the problem, a detailed repair plan was formulated and implemented when the corrector was removed from the telescope in April 2009. The problematic interface was replaced, and the four aspheric mirrors were optically tested and re-aligned. Individual mirror surface figures were confirmed to meet specification, and a full system test after the re-alignment yielded a root mean square wavefront error of 0.15 waves. The corrector was reinstalled in August 2010 and aligned with respect to the payload and primary mirror. Subsequent on-sky tests revealed spurious signals being sent to the tracker by the auto-collimator, the instrument that maintains the alignment of the corrector with respect to the primary mirror. After rectifying this minor issue, the telescope yielded uniform 1.1 arcsec star images over the full 10-arcmin field of view.

Assessing the quality of care of multiple conditions in general practice: practical and methodological problems  

PubMed Central

Objective: To investigate practical and methodological problems in assessing the quality of care of multiple conditions in general practice. Setting: Sixteen general practices from two socioeconomically diverse regions in the UK. Method: Quality of care was assessed in 100 randomly selected patient records in each practice using an established set of quality indicators covering 23 conditions commonly seen in primary care. Inter-rater reliability assessment was carried out for five of the conditions. Results: Conducting simultaneous quality assessment across multiple conditions is highly resource intensive. Poor data quality and the low prevalence of some items of care defined by the indicators are significant problems. Scores for individual indicators require very large samples for reliable assessment. Quality scores are more reliable when reported at a higher unit of analysis. This is particularly true for indicators and conditions with low prevalence where data may need to be aggregated to the level of groups of conditions or organisational providers. There is no single ideal way of aggregating quality scores. Conclusion: The study identified some of the practical and methodological difficulties in assessing quality of care across multiple conditions. For improved quality assessment, advances in information technology and improvements in data quality are required for more efficient and reliable data extraction from medical records, together with the development of methods for combining scores across indicators, conditions, and practices. However, electronic data extraction methods will still be based on the assumption that the care recorded reflects the care provided.

Causes of Indoor Air Quality Problems in Schools: Summary of Scientific Research  

SciTech Connect

In the modern urban setting, most individuals spend about 80% of their time indoors and are therefore exposed to the indoor environment to a much greater extent than to the outdoors (Lebowitz 1992). Concomitant with this increased habitation in urban buildings, there have been numerous reports of adverse health effects related to indoor air quality (IAQ) (sick buildings). Most of these buildings were built in the last two decades and were constructed to be energy-efficient. The quality of air in the indoor environment can be altered by a number of factors: release of volatile compounds from furnishings, floor and wall coverings, and other finishing materials or machinery; inadequate ventilation; poor temperature and humidity control; re-entrainment of outdoor volatile organic compounds (VOCs); and the contamination of the indoor environment by microbes (particularly fungi). Armstrong Laboratory (1992) found that the three most frequent causes of IAQ are (1) inadequate design and/or maintenance of the heating, ventilation, and air-conditioning (HVAC) system, (2) a shortage of fresh air, and (3) lack of humidity control. A similar study by the National Institute for Occupational Safety and Health (NIOSH 1989) recognized inadequate ventilation as the most frequent source of IAQ problems in the work environment (52% of the time). Poor IAQ due to microbial contamination can be the result of the complex interactions of physical, chemical, and biological factors. Harmful fungal populations, once established in the HVAC system or occupied space of a modern building, may episodically produce or intensify what is known as sick building syndrome (SBS) (Cummings and Withers 1998). Indeed, SBS caused by fungi may be more enduring and recalcitrant to treatment than SBS from multiple chemical exposures (Andrae 1988). An understanding of the microbial ecology of the indoor environment is crucial to ultimately resolving many IAQ problems. The incidence of SBS related to multiple chemical sensitivity versus bioaerosols (aerosolized microbes), or the contribution of the microorganisms to the chemical sensitivities, is not yet understood. If the inhabitants of a building exhibit similar symptoms of a clearly defined disease with a nature and time of onset that can be related to building occupancy, the disease is generally referred to as ''building-related illness.'' Once the SBS has been allowed to elevate to this level, buildings are typically evacuated and the costs associated with disruption of the building occupants, identification of the source of the problem, and eventual remediation can be significant. Understanding the primary causes of IAQ problems and how controllable factors--proper HVAC system design, allocation of adequate outdoor air, proper filtration, effective humidity control, and routine maintenance--can avert the problems may help all building owners, operators, and occupants to be more productive (Arens and Baughman 1996). This paper provides a comprehensive summary of IAQ research that has been conducted in various types of facilities. However, it focuses primarily on school facilities because, for numerous reasons that will become evident, they are far more susceptible to developing IAQ problems than most other types of facilities; and the occupants, children, are more significantly affected than adults (EPA 1998).

Benchmarking Strategies for Measuring the Quality of Healthcare: Problems and Prospects  

PubMed Central

Over the last few years, increasing attention has been directed toward the problems inherent to measuring the quality of healthcare and implementing benchmarking strategies. Besides offering accreditation and certification processes, recent approaches measure the performance of healthcare institutions in order to evaluate their effectiveness, defined as the capacity to provide treatment that modifies and improves the patient's state of health. This paper, dealing with hospital effectiveness, focuses on research methods for effectiveness analyses within a strategy comparing different healthcare institutions. The paper, after having introduced readers to the principle debates on benchmarking strategies, which depend on the perspective and type of indicators used, focuses on the methodological problems related to performing consistent benchmarking analyses. Particularly, statistical methods suitable for controlling case-mix, analyzing aggregate data, rare events, and continuous outcomes measured with error are examined. Specific challenges of benchmarking strategies, such as the risk of risk adjustment (case-mix fallacy, underreporting, risk of comparing noncomparable hospitals), selection bias, and possible strategies for the development of consistent benchmarking analyses, are discussed. Finally, to demonstrate the feasibility of the illustrated benchmarking strategies, an application focused on determining regional benchmarks for patient satisfaction (using 2009 Lombardy Region Patient Satisfaction Questionnaire) is proposed.

HACCP-based quality risk management approach to udder health problems on dairy farms  

PubMed Central

Against the background of prevailing udder health problems on dairy farms, this paper discusses a new approach to mastitis control. Current udder health control programmes, such as the 'five-point plan', are highlighted and their drawbacks indicated. The concept and principles of hazard analysis critical control points (HACCP) are introduced. The eight core elements of this concept are dealt with by using the example of a dairy herd with a mastitis problem due to Staphylococcus aureus. The various steps to be taken in the development of a HACCP-based quality risk management programme are illustrated through the application of core elements. Finally, it is shown that the HACCP key words, structure, organisation, planning, communication and formalisation; which do not frequently appear in conventional herd health and production management programmes can contribute to better udder health. The role of the veterinarian can be paramount and of added value, if he/she is willing to invest in new knowledge and skills, such as the HACCP concept, farm economics, animal nutrition, and particularly the role of coach to the dairy farmer in the implementation of preventative measures in relation to udder health.

Health-related quality of life and cancer clinical trials  

PubMed Central

The measurement of patient-reported outcomes, including health-related quality of life, is a new initiative which has emerged and grown over the past four decades. Following the development of reliable and valid self-report questionnaires, health-related quality of life has been assessed in tens of thousands of patients and a wide variety of cancers. This review is based on a selection of data published in the last decade and is intended primarily for healthcare professionals. The assessments in clinical trials have been particularly useful for elucidating the effects of various cancers and their treatments on patients’ lives and have provided additional information that enhances the usual clinical endpoints used for determining the benefits and toxicity of treatment. With growing experience the quality of the health-related quality of studies has improved and, in general, recent studies are more likely to be methodologically robust than those that were performed in earlier decades. Health-related quality of life has become a more accurate predictor of survival than some other clinical parameters, such as performance status. The overall outlook for the routine assessment of patient-reported outcomes in clinical trials is assured and, eventually, it is likely to become a standard part of clinical practice. However, there is still a need for a clear method for determining the clinical meaningfulness of changes in scores. The answer will probably come from the greater use of patient-reported outcomes and the consequent growth of experience that is necessary to make such judgements.

Sleep quality as a mediator between technology-related sleep quality, depression, and anxiety.  

PubMed

This study examines (a) relations among technology use during sleep time, sleep quality, and depression/anxiety and (b) time awake due to technology use. Two hundred thirty-six college students completed self-report questionnaires and week-long sleep diaries. Results revealed that 47 percent of students reported night-time waking to answer text messages and 40 percent to answer phone calls. Regression analyses indicated that higher levels of technology use after the onset of sleep predicted poorer sleep quality, and poorer sleep quality predicted symptoms of depression/anxiety. Finally, sleep quality is a mediator between technology use after the onset of sleep and depression/anxiety. College students who have difficulty setting boundaries around technology use may be at increased risk for psychological health concerns. PMID:23320870

Relations between sleep, fatigue and health-related quality of life in individuals with insomnia  

PubMed Central

Objective This study explored the relations between sleep, fatigue and health-related quality of life in a sample of individuals with chronic insomnia. Methods A total of 160 adults meeting diagnostic criteria for chronic insomnia underwent three nights of polysomnography (PSG) and completed sleep diaries and questionnaires assessing daytime functioning including fatigue and health-related quality of life. Results A cluster analysis was conducted based on PSG-defined sleep disturbances and fatigue severity. A four-cluster solution (R2 = 0.68) was found, classifying individuals as having either (a) both severe sleep disturbance and severe fatigue (n = 15); (b) severe sleep disturbance but milder fatigue (n = 15); (c) milder sleep disturbance but severe fatigue (n = 68) or (d) both milder sleep disturbance and milder fatigue (n = 61). Health-related quality of life was lower in both clusters with severe fatigue compared to those with milder fatigue, and was further decreased when severe sleep disturbances were present. Relations between several indicators of fatigue and health-related quality of life were then examined using factor analysis in order to identify different domains of impairment. A three-factor structure was selected, suggesting that daytime symptoms can be classified as relating to fatigue, physical health, or mental health. These different subtypes of daytime impairment were predicted by distinct sets of variables. Conclusion More severe fatigue is not necessarily related to poorer PSG-defined sleep but appears associated with greater impairment in health-related quality of life. Fatigue and health-related quality of life appear to be distinct but interrelated constructs.

The Shapes of Galaxy Clusters and Related Problems  

NASA Astrophysics Data System (ADS)

The cosmological many body problem describes the gravitational clustering of galaxies in the universe. These galaxies cluster about each other to produce some of the largest structures in the universe. These structures are modeled by the gravitational quasi-equilibrium distribution (GQED). The GQED is a fairly robust and simple theory based on thermodynamics and statistical mechanics that, in its simplest form, describes galaxies as point masses of equal mass. We show that more realistic descriptions of the universe only introduce higher order corrections to the theory, and the simple description is sufficient to model most cases of galaxy clustering. To demonstrate this, we use data from the Sloan Digital Sky Survey (SDSS) to show that the observed counts-in-cells distribution of galaxies in the universe follows the GQED. Using the GQED, we develop a theory to study the structure of clusters and groups of galaxies, relating the internal structure of a cluster to the large scale structure of the universe. This theory describes the probability that the galaxies in a region of space have a given kinetic and correlation potential energy. These energies are closely related to the 6-dimensional phase space configuration and thus the shape and structure of a cluster of galaxies. This theory suggests that clusters of galaxies with more than 10 members are very likely to be bound and virialized on average, but may also contain substructure in the form of smaller subclusters that cluster about each other. These subclusters may be the cores of smaller clusters that have merged, which means that the merger history of a cluster may be an important factor that determines its internal structure. Because the full 6-dimensional phase space configuration of a cluster of galaxies cannot be observed, direct comparisons with observations are not possible. Instead, we attempt to model the unobservable dimensions and show that on a statistical basis, the kinetic energies of clusters in the SDSS agrees with theory. However, we also find that the correlation potential energies of cells have additional uncertainties caused by merging galaxies that require more detailed models to resolve.

Alcohol misuse is common in the elderly, and the problem may be compounded by the body's reduced ability to metabolise ethanol and interactions with over-the-counter and prescription drugs. Older heavy drinkers are likely to present with mental health problems--anxiety, depression, dementia, confusion and sleep disturbance--or physical problems--gait disturbance, falls and liver disease. Alcohol use must be accurately assessed, and physical, neurological and mental state examinations performed.

Problems faced by relatives caring for cancer patients at home.  

PubMed

The care of patients suffering from advanced cancer is not limited in the hospital setting. It continues at home where the burden of care is borne by specific individuals. The aim of the present study was to survey and record the various problems faced by those who care for cancer patients at home. The study was conducted in our hospital during the summer of 2007. All participants completed, during a personal interview, a questionnaire which covered pathologic, social, psychological, spiritual/religious and financial problems. Seventy-six carers returned fully completed questionnaires. The most frequent problems reported were: anxiety regarding the patient's future (61.8%), troublesome symptoms such as pain (54%), increased economic burden-financial difficulty (51.3%), problems with patient's feeding (50%), unhappiness or depression (48,7%), emotional upset (47.4%), worsening of the patient's behaviour and personality (38.2%), difficulty of establishing a positive attitude regarding their current status (34.2%), transport to hospital (32.9%), assistance from the wider family circle (25%). Taking care of cancer patients at home creates several problems among carers. Many of them remain undetected. The acknowledgement and recognition of these problems by health-care professionals might contribute to finding solutions in order to assist the difficult task of these individuals. PMID:19187163

Bacteriological monitoring and sustainable management of beach water quality in Malaysia: problems and prospects.  

PubMed

Despite the growing demand of tourism in Malaysia, there are no resolute efforts to develop beaches as tourist destinations. With no incentives to monitor public beaches or to use them in a sustainable manner, they might eventually degenerate in quality as a result of influx of pollutants. This calls for concerted action plans with a view to promoting their sustainable use. The success of such plans is inevitably anchored on the availability of robust quality monitoring schemes. Although significant efforts have been channelled to collation and public disclosure of bacteriological quality data of rivers, beach water monitoring appears left out. This partly explains the dearth of published information related to beach water quality data. As part of an on-going nation-wide surveillance study on the bacteriological quality of recreational beaches, this paper draws on a situation analysis with a view to proffering recommendations that could be adapted for ensuring better beach water quality in Malaysia.

The relation between problem categorization and problem solving among experts and novices  

NSDL National Science Digital Library

These investigations were conducted to examine the relationship between problem-solving ability and the criteria used to decide that two classical mechanics problems would be solved similarly. We began by comparing experts and novices on a similarity judgment task and found that the experts predominantly relied on the problems' deep structures in deciding on similarity of solution, although the presence of surface-feature similarity had a clear adverse effect on performance. The novices relied predominantly on surface features, but were capable of using the problems' deep structures under certain conditions. In a second experiment, we compared groups of novices, at the same level of experience, who tended to employ different types of reasoning in making similarity judgments. Compared to novices who relied predominantly on surface features, novices who made greater use of principles tended to categorize problems similarly to how experts categorized them, as well as score higher in problem solving. These results suggest that principles play a fundamental role in the organization of conceptual and procedural knowledge for good problem solvers at all levels.

Dutch policy on the management of drug-related problems.  

PubMed

It is argued that the drug abuse problem should not be primarily seen as a problem of police and justice. It is essentially a manner of health. The Dutch acknowledge that the international repressive, prohibitive approach leads to unintentional negative side-effects, both for the individual and for society. They try to avoid a situation in which consumers of cannabis suffer more damage from the criminal proceedings than from the use of the drug itself. They opt rather for a realistic and practical approach to the drug problem than for a moralistic and over-dramatized one. The Dutch alternative is the normalization of the drug problem, as a pragmatic compromise between two extreme options: an intensified war on drugs and legalization. The implications of the normalization approach for the prevention and treatment policies are discussed: AIDS-prevention, harm reduction instead of detoxification and de-mystification. It is suggested that the policy of normalization is rather successful and does not produce an increase of drug use. PMID:2785828

We are developing a multiphysics simulation tool for Very High-Temperature gascooled Reactors (VHTR). The simulation tool, PRONGHORN, takes advantages of the Multiphysics Object-Oriented Simulation library, and is capable of solving multidimensional thermal-fluid and neutronics problems implicitly in parallel. Expensive Jacobian matrix formation is alleviated by the Jacobian-free Newton-Krylov method, and physics-based preconditioning is applied to improve the convergence. The initial development of PRONGHORN has been focused on the pebble bed corec concept. However, extensions required to simulate prismatic cores are underway. In this progress report we highlight progress on application of PRONGHORN to PBMR400 benchmark problems, extension and application of PRONGHORN to prismatic core reactors, and progress on simulations of 3-D transients.

Problem solving skills predict quality of life and psychological morbidity in ALS caregivers.  

PubMed

Amyotrophic lateral sclerosis (ALS) often is associated with a particularly intensive caregiving experience, and the well-being of caregivers impacts that of patients. Thus, identification of factors leading to distress in caregivers may provide avenues for intervention that will help both the caregiver and the patient. We prospectively examined caregivers' social problem solving skills, the quality of the patient-caregiver relationship, caregivers' spirituality and religiousness, and the ways in which these impact caregivers' quality of life (QoL) and psychological morbidity in 75 caregivers of ALS patients. Data were analyzed through correlational and hierarchical multiple regression analyses. Social problem solving and spirituality were the best predictors of caregivers' QoL, accounting for 15.6% and 7.8% of the variance in QoL, respectively (F (2, 69) = 11.83, p<.001). Social problem solving also predicted and accounted for 25.4% of the variance in psychological morbidity (F (1, 71) = 25.571, p<.001). Level of care provided did not predict either QoL or psychological morbidity in caregivers. In conclusion, the problem-solving skills of ALS caregivers are an important determinant of caregiver well-being. Developing interventions to teach ALS caregivers effective methods of problem solving would probably be beneficial to this population. PMID:18618351

Autism severity and qualities of parent-child relations.  

PubMed

The aim of this study was to examine how severity of autism affects children's interactions (relatedness) and relationships with their parents. Participants were 25 parent-child dyads that included offspring who were children with autism aged from 4 to 14 years. The severity of the children's autism was assessed using the calibrated severity metric of the Autism Diagnostic Observation Schedule (Gotham et al. in J Autism Dev Disord 39:693-705, 2009). Parent-child dyads were videotaped in 10-min semi-structured play interactions, and qualities of interpersonal relatedness were rated with the Dyadic Coding Scales (Humber and Moss in Am J Orthopsychiatr 75(1):128-141, 2005). Quality of relationships between parents and children were evaluated with a parent self-report measure, the Parent Child Relationship Inventory (Gerard in Parent-Child Relationship Inventory (PCRI) manual. WPS, Los Angeles, 1994). Multivariate regression analysis revealed that severity of autism was inversely related to patterns of parent-child interaction but not to reported quality of parent-child relationship. We consider the implications for thinking about relatedness and relationships among children with autism, and opportunities for intervention. PMID:22673860

Health-related quality of life in women after cancer treatment.  

PubMed

Cancer survivorship is the term used to represent the state or process of living with cancer or living after diagnosis of cancer. Living with cancer or living after cancer--are conditions characteristic to an increasing number of long-term survivors ("society of remission"); health-related quality of life in these individuals is an important indicator of successful treatment and patient's satisfaction. Health-related quality of life in oncological patients has remained one of the main topic of research. The present paper reviews psychosocial outcomes in breast cancer (female disease) and gender-related differences in health-related quality of life in colon cancer survivors. Breast cancer diagnosis is usually associated with several expected psychosocial consequences like psychosocial distress. Specific psychological variables like body image, fear, satisfaction with treatment and cosmetic evaluation may improve general will to live. Women who perceive support from family and friends have better coping and psychological adjustment, while lack of social support is a risk factor for anxiety and depression. Colon cancer remains an important medical and social problem in Poland; polish data showed the following gender-related differences: in patients with stoma, women reported lower level of psychological well-being than men, reported increasing level of stress and loss of control over emotions and behaviours.

How to evaluate the quality of health related websites.  

PubMed

To establish reliable quality criteria for medical websites is of foremost importance in relation to the increasing number of Internet users, both health professionals and lay people, searching for medical information in the mass of these sites. Quality in general refers to a set of features that distinguish one person or thing from others of the same type. The quality of a website is usually related to its content and usability. The first criteria we considered are contents and readability, which must be targeted to the intended type of user. Other important criteria include: transparency, consistency, honesty, references to sources, accountability, respect of privacy, currency of content material, responsibility, and accessibility. Technical criteria are the use of consolidated and standard technologies, soft colours, short page download time. Good medical websites should also follow the suggestions of organizations such as the World Health Organization, the Food and Drug Administration, the European Communities. Another organization, Health On Net Foundation, has issued some guidelines for medical websites, summarized in eight points, fundamental to assign real scientific value to a site. We believe, in agreement with the literature, that it is unnecessary to apply strict rules to medical website developers. We want to stress the importance of guidelines and recommendations to be modified with the development of web technology and the cultural evolution of patient and physicians. In the near future the presence on the Internet of websites certified by national or international medical web authorities will lead users to trust and give their preference to such sites, leading to the self-regulation of website developers and users.

The dichotomy of relative humidity on indoor air quality.  

PubMed

Dry and irritated mucous membranes of the eyes and airways are common symptoms reported in office-like environments. Earlier studies suggested that indoor pollutants were responsible. We have re-evaluated, by review of the literature, how low relative humidity (RH) may influence the immediately perceived indoor air quality (IAQ), including odour, and cause irritation symptoms (i.e. longer-term perceived IAQ). "Relative humidity" were searched in major databases, and combined with: air quality, cabin air, dry eyes, formaldehyde, inflammation, mucous membranes, offices, ozone, pungency, sensory irritation, particles, precorneal tear film, sick building syndrome, stuffy air, and VOCs. The impact of RH on the immediately and longer-term perceived IAQ by VOCs, ozone, and particles is complex, because both the thermodynamic condition and the emission characteristics of building materials are influenced. Epidemiological, clinical, and human exposure studies indicate that low RH plays a role in the increase of reporting eye irritation symptoms and alteration of the precorneal tear film. These effects may be exacerbated during visual display unit work. The recommendation that IAQ should be "dry and cool" may be useful for evaluation of the immediately perceived IAQ in material emission testing, but should be considered cautiously about the development of irritation symptoms in eyes and upper airways during a workday. Studies indicate that RH about 40% is better for the eyes and upper airways than levels below 30%. The optimal RH may differ for the eyes and the airways regarding desiccation of the mucous membranes. PMID:17499853

Work-related respiratory problems in industrial arts teachers.  

PubMed

Because of reports of respiratory complaints in Swedish industrial arts (IA) teachers, a cross-sectional study was performed on 130 IA teachers in Stockholm to study the relationship between the work environment and health, and especially the aforementioned complaints. One hundred and twelve other school employees served as control subjects. Sex, age, and smoking habit distribution were similar in the two groups. All subjects answered a questionnaire about their health problems, and the IA teachers answered questions about their work environment. The work environment consisted of many old and neglected workshops (hereafter called shops). Compared to the control subjects, the IA teachers had more complaints in respect of the skin, eyes, nose, throat, and lower airways--including chronic bronchitis (OR 12.4, 95% confidence interval 2.95-110.5). A higher occurrence of symptoms existed in shops with bad ventilation and dust-spreading machines and in shops where dust-spreading cleanup methods were used. A suspected interaction between smoking and work environment was noted for some symptoms, especially impaired smell and chronic bronchitis. In conclusion, several factors in the work environment were identified as risk factors for health. Identification of these risk factors should result in a program to reduce the health problems in the work environment. PMID:7672854

Consequences of non-vascular trans-femoral amputation: a survey of quality of life, prosthetic use and problems.  

PubMed

Individuals with unilateral trans-femoral amputations due to non-vascular causes were studied in a mailed survey designed to investigate health-related quality of life (HRQL), prosthetic use and problems. The Swedish SF-36 Health Survey and a structured questionnaire designed for trans-femoral amputees were used. The series consisted of 97 subjects (60 men, 37 women), aged 20 to 69 years with a mean of 22 years since the amputation. Trauma was the cause of amputation in 55%, tumour in 35% and other causes in 10%. Ninety-two (92) subjects (95%) had a prosthesis and 80 (82%) used it daily. General HRQL was significantly lower than Swedish age- and gender-matched norms in all dimensions as measured by SF-36. Most frequently reported problems that had led to reduction in quality of life were heat/sweating in the prosthetic socket (72%), sores/skin irritation from the socket (62%), inability to walk in woods and fields (61%) and inability to walk quickly (59%). Close to half were troubled by stump pain (51%), phantom limb pain (48%), back pain (47%) and pain in the other leg (46%). One fourth considered themselves to have a poor or extremely poor overall situation. Transfemoral amputation, due to non-vascular causes, has an evident impact on quality of life and there are considerable problems related to the amputation and the prosthesis. Efforts to improve the physical and the psychological well-being for this group, with a long life expectancy, are needed. PMID:11860092

China's tax system relatively benign, but problems remain  

SciTech Connect

Recent developments in China's oil market have reignited the interest of multinational oil and gas companies in China. New onshore and offshore blocks are being granted, and the Tarim basin has been opened to foreign participation for the first time. Foreign participation is also being sought in refining and other downstream areas. Though Chinese officials have long been viewed as difficult negotiators, the tax provisions applicable to oil and gas exploration and production in China are some of the more generous in the area. This article describes some of the relevant features of the system and some of the problem areas. The paper describes production sharing contracts, applicable taxes, gross income determination, taxable income, tax consolidation, overseas charges, and withholding taxes on payments to subcontractors and employees.

Smoking habit profile and health-related quality of life.  

PubMed

Background: Few studies have investigated the relationship between smoking and health-related quality of life (HRQOL), and the results are not consistent. The aim of this study is to explore the association between smoking and HRQOL. Method: Cross-sectional study of 714 Spanish adults (44.7% never smokers and 55.3% smokers) without diagnosis of physical or mental disorder. Each participant provided information about different sociodemographic variables and data on HRQOL. Smokers also reported smoking-related information about smoking-related variables. Results: Nicotine dependence was not associated with the physical dimension of HRQOL, but in the mental component, nicotine dependent smokers showed worse HRQOL than never smokers (p = 0.004) and than non-nicotine dependent smokers (p = 0.014). There were no differences between no-nicotine dependent smokers and never smokers. Smoking status (non smokers vs. smokers), number of cigarettes smoked per day, stage of change, quit attempts in the past year or age of smoking onset were not related to HRQOL. Conclusions: In subjects without physical or mental diseases, only nicotine dependent smokers showed a significant impairment in the mental component of HRQOL. Therefore, it is important to consider nicotine dependence in the relationship between smoking and HRQOL. PMID:24124772

Effect of disease burden on health-related quality of life in patients with malignant gliomas.  

PubMed Central

The burden imposed by disease recurrence in patients with high-grade gliomas is not well documented. We studied the frequency of self-report symptoms and the effects on health-related quality of life in patients who had recurrent glioblastoma multiforme or anaplastic astrocytoma and who had a Karnofsky performance score > or = 70. Patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Items (QLQ-C30) and the Brain Cancer Module (BCM20) before initiation of treatment for first recurrence of disease. Six symptoms (fatigue, uncertainty about the future, motor difficulties, drowsiness, communication difficulties, and headache) were reported with a frequency > 50% by both groups of patients. An additional two symptoms (visual problems and pain) were also reported with frequencies of > 50% by patients with recurrent glioblastoma multiforme. Most of the symptoms were likely due to recurrence, but previous radiation therapy and on-going corticosteroid treatment may have also been casual factors for fatigue, whereas uncertainty about the future and pain were probably nonspecific for brain cancer. Problems with motor functioning, vision, leg strength, and pain were reported more frequently by patients with recurrent glioblastoma multiforme than by those with recurrent anaplastic astrocytoma. Scores on health-related quality-of-life functioning scales were similar in the two groups. Finally, the scores for patients who had recurrent high-grade gliomas and a Karnofsky performance score > or = 70 were compared with the reported health-related quality of life scores of patients with other cancers. Their scores were similar to those of patients with metastatic cancers and worse than those of patients with localized cancers.

Relationship Between Sleep Problems and Quality of Life in Children With ADHD.  

PubMed

Objective: The purpose of this study is to assess the sleep behaviors, sleep problems and frequency, and relationship with psychiatric comorbidities in ADHD Combined type and to evaluate the effect of sleep problems on quality of life. Method: Forty-six boys, aged 7 to 13 years, with ADHD-combined type and 31 healthy boys were included. ADHD children were never treated for sleep or psychiatric disorders. Intelligence quotient (IQ) test scores were minimum 80, body mass index were normal and did not have medical disorders. Parents completed Children's Sleep Habits Questionnaire, Conners' Parent Rating Scale and The Pediatric Quality of Life Inventory (PedsQL) and participants were asked about sleep behaviors and were administered PedsQL and Schedule for Affective Disorders and Schizophrenia. Results: The frequency of sleep problems in ADHD is 84.8%, higher than the control group (p = .002). Evaluating PedsQL scores, the quality of life is worse in physical, psychosocial health, and total life quality (p < .05). ADHD group with sleep problems have more night wakings than control group with sleep problems (p = .02). The comorbidity do not increase sleep problems. The frequency of parasomnias is increased in group with learning disorders (p = .05). Conclusion: The results of this study, which controls for a number of possible confounders found in previous examinations of ADHD and sleep, support the results of a number of other studies that have found an increased overall prevalence of parent-reported sleep disturbances in children with ADHD compared with healthy control participants. As the ADHD group have more night wakings than the control group through the night, it is thought that night wakings that cause a partitioned sleep may be important signs seen in ADHD. That could be suggested by two hypotheses. First one is that, daytime sleepiness is more common in ADHD and those children present excessive hyperactivity during the day to stay awake and the second one is the improvement of ADHD signs when the drugs for sleepiness are used. Usage of standardized and valid diagnostic criteria, exclusion of adolescence, gender, socioeconomic level, primary sleep problems, medical disorders and low IQ level, making allowances for effect of comorbidities and having compared with the control group are the important methodological features of this study. The most important limitation of this study is small sample size that makes the findings less generalizable to other groups of children with ADHD, and another one is not having used objective measurements together with subjective measurements. In conclusion, these results underscore the importance of screening all children who have a symptom constellation suggestive of ADHD for sleep problems that may either play a causative role or exacerbate the clinical appearance of ADHD in a given child. Correct evaluation and treatment of sleep problems increase the life quality of family and child and also decrease the severity of ADHD symptoms. (J. of Att. Dis. 2013; XX(X) 1-XX). PMID:23511553

Health-related quality of life between naturalism and hermeneutics.  

PubMed

Interest in measuring Quality of life (QOL) in modern medicine has increased considerably in recent years. However, there is no generally agreed definition of QOL, but the term encompasses several constructs, including physical, functional, emotional, social and cognitive domains. A psychometric approach is typically applied, but major problems conceptual confront this tradition. It is argued that QOL research follows a naturalistic tradition in medicine, and that the theoretical status of the QOL concept remains ambiguous. Hence, the more neutral term multidimensional evaluation is suggested as more appropriate than QOL. Hermeneutic thinking with its focus on meaning, understanding and interpretation of the individual placed in a historical and social context is briefly introduced and its role for QOL discussed. A radical hermeneutic position focusing solely on the subjectivity of the individual is rejected, and a balanced view is suggested. Such a view should not ignore that man is a biological organism which can be subjected to naturalistic studies, but it should also take into account those features which constitutes man as a person, e.g. understanding and interpretation. Future QOL research may benefit from an integration of philosophical reflection on health and disease issues and a psychometric tradition. PMID:8560309

A conceptual model of health-related quality of life in sarcoidosis.  

PubMed

PURPOSE: Sarcoidosis is a multisystem disease that commonly affects the lung, eye, skin, and lymphatic systems. Organ function has been a major focus of treatment outcome with less attention given to more subjective impacts, such as health-related quality of life (HRQL). The purpose of this paper is to present a conceptual model of HRQL in sarcoidosis, which was developed through patient and clinician input. METHODS: We surveyed sarcoidosis clinical experts (n = 5) regarding disease-specific symptoms and their impact on their patient's lives. We also conducted three sarcoidosis patient focus groups (n = 22) that reflected major sarcoidosis typologies (lung, skin, and eye). Data were coded and summarized using qualitative methodologies. RESULTS: Clinicians highlighted the following domains as being important (relative frequencies for comments are in parentheses): emotional distress (17 %), lung problems (14 %), pain (14 %), physical limitations (14 %), fatigue (10 %), social limitations (10 %), eye problems (7 %), skin problems (7 %), sleep disturbance (3 %), and constitutional symptoms (3 %). Similarly, patients highlighted the following domains: social limitations (14 %), skin problems (12 %), pain (10 %), coping (10 %), emotional distress (9 %), lung problems (8 %), eye problems (7 %), negative impact of corticosteroids (7 %), physical limitations(6 %), fatigue (6 %), sleep disturbance (3 %), constitutional symptoms (2 %), comorbidities (2 %), other systems affected (2 %), environmental factors (1 %), and positive impact of corticosteroids (1 %). CONCLUSIONS: Clinician and patient responses overlapped in several domains, including emotional distress, physical and social limitations, and sarcoidosis-specific impacts, such as eye, skin, and lung problems. These findings support the HRQL impact of sarcoidosis and provide the basis for a conceptual model which has the potential to inform new patient-reported outcomes measures for this population.

Differences in sleep quality and health-related quality of life in young adults with allergies and asthma and their healthy peers.  

PubMed

Abstract Objective: The current study examined the relationship between sleep quality and health-related quality of life (HRQOL). Participants: Participants were 501 undergraduate students with allergies (167), asthma + allergies (167), or with no history of a chronic illness (167) completed study measures from August 2011 to April 2012. Methods: The undergraduate students completed questionnaires online as part of a larger study of psychosocial adjustment of young adults. Results: Young adults with allergies and asthma + allergies reported significantly worse sleep quality and HRQOL than healthy peers. Additionally, those with allergies and asthma + allergies had significantly more sleep disturbances and used sleeping medication significantly more often in the previous month than healthy peers. Conclusions: These results highlight concerns regarding quality of life and sleep problems in an often-overlooked population. Importantly, sleep difficulties can result in difficulties in daily living and impairment in academic functioning. PMID:24152026

[Work-related diseases--a medical problem or a social problem?].  

PubMed

The author presents, on the basis of the available literature, an issue of work-related diseases which are identified as diseases of multi-factor etiology. This group of diseases can be induced or progressed by unfavourable working conditions. Among them, the effect of certain chemicals, dust pollution, unphysiological job performance and psycho-social factors plays an essential role. Because of multi-factor etiology of some work-related diseases such as back pains, arterial hypertension, ischaemic heart disease, chronic bronchitis and psycho-somatic illnesses, the diagnosis, collection of information on the incidence and undertaking of preventive measures involve a muldisciplinary system of health care, mainly based on occupational health services.

A Cube Dismantling Problem Related to Bootstrap Percolation  

NASA Astrophysics Data System (ADS)

An n× n×⋯× n hypercube is made from n d unit hypercubes. Two unit hypercubes are neighbours if they share a ( d-1)-dimensional face. In each step of a dismantling process, we remove a unit hypercube that has precisely d neighbours. A move is balanced if the neighbours are in d orthogonal directions. In the extremal case, there are n d-1 independent unit hypercubes left at the end of the dismantling. We call this set of hypercubes a solution. If a solution is projected in d orthogonal directions and we get the entire [ n] d-1 hypercube in each direction, then the solution is perfect. We show that it is possible to use a greedy algorithm to test whether a set of hypercubes forms a solution. Perfect solutions turn out to be precisely those which can be reached using only balanced moves. Every perfect solution corresponds naturally to a Latin hypercube. However, we show that almost all Latin hypercubes do not correspond to solutions. In three dimensions, we find at least n perfect solutions for every n, and we use our greedy algorithm to count the perfect solutions for n?6. We also construct an infinite family of imperfect solutions and show that the total size of its three orthogonal projections is asymptotic to the minimum possible value. Our results solve several conjectures posed in a proceedings paper by Barát, Korondi and Varga. If our dismantling process is reversed we get a build-up process very closely related to well-studied models of bootstrap percolation. We show that in an important special case our build-up reaches the same maximal position as bootstrap percolation.

Health-related quality of life in migrant preschool children  

PubMed Central

Background Minority groups have a lower health-related quality of life (HRQOL), but there is little information if this finding also applies to children. In this study, we compared HRQOL between young children with and without migrant parents. Methods Two cross-sectional studies of culturally diverse preschool populations in Switzerland: Ballabeina (40 preschools, 258 girls and 232 boys aged 4 to 6 years) and Youp’là Bouge (58 child care centers, 453 girls and 522 boys aged 2 to 4 years). Most children were born in Switzerland (Ballabeina: 92.3%; Youp’là Bouge: 93.7%). Number of migrant parents was considered as the main exposure. HRQOL was measured using the 23-item Pediatric Quality of Life Inventory.

Breast Cancer Survivors' Health-related Quality of Life  

PubMed Central

Background Small samples with few minority women and/or the absence of comparisons to peers without cancer histories have limited previous research suggesting racial differences in breast cancer survivors’ health-related quality of life (HRQoL). The present study not only compares HRQoL of African American and white breast cancer survivors, but also compares the HRQoL of these women to that of same race women with no cancer history. Methods Data from the Women’s Health Initiative-Observational Study were used including 5,021 cancer survivors and 88,532 women without a history of cancer. Multivariable regression analyses estimated differences in breast cancer survivors’ baseline HRQoL (RAND36), depressive symptoms (CES-D short-form), and sleep quality (WHIIRS). Results African American breast cancer survivors reported worse physical functioning and general health compared to white survivors. Among African Americans, survivors reported worse role limitations due to physical health, pain, general health, and vitality than women without a history of cancer. This was most evident in those with more recent diagnoses. Most significant differences between groups were small in magnitude (Cohen’s d=.21-.36). Conclusions These results add to the increasing knowledge of cancer disparities by showing that African American women have small but clinically meaningful decrements in physical HRQoL compared to white survivors and to African American women without cancer. Since African American women also face diagnosis with higher grade tumors and higher breast cancer mortality, more research is needed to examine the physical and psychosocial experiences of African American breast cancer survivors to elucidate the mechanisms leading to poorer outcomes.

Prejudices and elderly patients' personality - the problem of quality of care and quality of life in geriatric medicine  

PubMed Central

Background The article discusses the position of elderly patients in the context of medical intervention. The phenomenon of a “greying” population has changed the attitude towards the elderly but common observations prove that the quality of geriatric care is still unsatisfactory. This is a comparative study of personality among people at different ages, designed to improve specialists’ understanding of ageing. The results are discussed in relation to the elderly patient-centered paradigm to counterbalance ageist practices. Material/Methods This study involved 164 persons in early and late adulthood. Among the old, there were the young old (ages 65–74) and the older old (ages 75+). All participants were asked to fill-out the NEO-FFI [11]. Results The results demonstrate age-related differences in personality. In late adulthood, in comparison to early adulthood, there is decreased openness to new experiences. Two traits – agreeableness and conscientiousness – increase significantly. Age did not differentiate significantly the level of neuroticism or extraversion. The results of cluster analyses show differences in taxonomies of personality traits at different periods of life. Conclusions The results challenge the stereotypes that present older people as neurotic and aggressive. Age did not significantly influence the level of neuroticism or extraversion. In general, the obtained results prove that the ageist assumption that geriatric patients are troublesome is false. This article builds support for effective change in geriatric professional practices and improvement in elderly patients’ quality of life.

Health-related Quality of Life in Emphysema  

PubMed Central

Patients with emphysema may experience reduced health-related quality of life (HRQOL). HRQOL measures have evolved from two different measurement traditions: psychometric theory and decision theory. Psychometric methods typically create a profile of outcomes, whereas decision theory methods offer a summary score on a continuum ranging from 0.0 (for death or worst possible health) to 1.0 (for best possible health). Decision theory methods are better suited for cost-effectiveness studies. Generic HRQOL measures can be applied to any disease population, whereas disease-targeted measures are tailored to a specific clinical condition. Disease-targeted measures are typically more sensitive to clinical change, but cannot offer a comparison basis for different clinical conditions. This article reviews the measurement of HRQOL in patients with emphysema. The National Emphysema Treatment Trial (NETT) offers an example of the application of both generic and disease-targeted, as well as profile and decision theory, methods. The NETT illustrates how HRQOL measures can be used to assess outcomes and estimate cost-effectiveness in a major clinical trial.

Health-related quality of life in Icelandic school children.  

PubMed

This study evaluated generic health-related quality of life (HRQOL) among 10 to 12-year-old Icelandic school age children who were either with or without chronic health condition. The children and their parents answered self-report questionnaires. For the 480 children who participated, girls were found to perceive their HRQOL significantly higher than the boys, children who visited the school nurse over a one-week period and children who indicated they were bullied by other children, perceived their HRQOL to be significantly lower than children who did not visit the school nurse over this time period or children who did not indicate they were bullied by other children in school. From the stepwise regression analysis, perception of health, school connectedness, health promotion, bullying victimization, visits to the school nurse and age, significantly predicted 43.8% of the variance of the girls' perception of their HRQOL. However, perception of health, school connectedness, and chronic health condition/illnesses, bullying victimization and after school activities predicted 48.1% of the boys' perception of their HRQOL. Children with chronic health condition or illnesses, reported their HRQOL to be significantly lower than children without chronic health condition. Assessing HRQOL among 10 to 12-year-old children might be helpful to take preventive action early on in children's life and development. PMID:16756527

[Quality of life related to public health and the health system reflections].  

PubMed

Quality of life (QL) is used to measure the well-being of the individual, the population and the quality of the health system. The QL related to the health has three approaches: To identify the perception of the individual on the way the disease affects the QL; to evaluate the effect of a treatment on the physical, emotional and well-being of the individual and to identify the necessities for health of the population. The aim is to evaluate publications on QL, and its use for evaluation of the health. Forty two studies were evaluated (2002-2008) on QL, 21 (50 %) were related to methodological and conceptual aspects or to describe instruments for evaluation; 13(31 %) were related to research work using questionnaires and 8(19 %) to projects that used specific forms. The integration of research groups must be encouraged related to QL in healthy groups, as well as in groups carrying problems of health; to evaluate the damage and the impact of the health intervention through controlled clinical trials. Because the affection of the population with a disease has effect on the psychological and social domains, the need for a multidisciplinary equipment to attend health, where the educative aspect acquires a preponderant role is suggested.

Relation between microbiological quality, metabolite production and sensory quality of equilibrium modified atmosphere packaged fresh-cut produce.  

PubMed

The quality of four types of fresh-cut produce, packaged in consumer-sized packages under an equilibrium modified atmosphere and stored at 7 degrees C, was assessed by establishing the relation between the microbial outgrowth and the corresponding production of nonvolatile compounds and related sensory disorders. In vitro experiments, performed on a lettuce-juice-agar, demonstrated the production of nonvolatile compounds by spoilage causing lactic acid bacteria and Enterobacteriaceae. Pseudomonas fluorescens and yeasts, however, were not able to produce detectable amounts of nonvolatile metabolites. The type of spoilage and quality deterioration in vivo depended on the type of vegetable. Mixed lettuce and chicory endives, leafy tissues, containing naturally low concentrations of sugars, showed a spoilage dominated by Gram-negative microorganisms, which are not producing nonvolatile compounds. Sensory problems were associated with visual properties and the metabolic activity of the plant tissue. Mixed bell peppers and grated celeriac, on the other hand, demonstrated a fast and intense growth of spoilage microorganisms, dominated by lactic acid bacteria and yeasts. This proliferation resulted in detectable levels of organic acids and the rejection by the trained sensory panel was based on the negative perception of the organoleptical properties (off-flavour, odour and taste). The applied microbiological criteria corresponded well with detectable changes in sensory properties and measurable concentrations of nonvolatile compounds, surely in the cases where lactic acid bacteria and yeasts were provoking spoilage. Consequently, the freshness of minimally processed vegetables, sensitive for outgrowth of lactic acid bacteria and yeasts (e.g., carrots, celeriac, bell peppers, mixtures with non-leafy vegetables) can be evaluated via analysis of the produced nonvolatile compounds.

The US Environmental Protection Agency on March 22 released its annual air quality trends report showing continued long-term progress for all pollutants. But the report also shows that ozone and carbon monoxide problems continue to plague many major metropolitan areas. The study, National Air Quality and Emissions Trends Report, 1987, shows that during the 10-year period 1978-1987: Lead levels in the air decreased 88 percent and dropped 19 over last year. Ambient carbon monoxide levels decreased 32 percent over long term and six percent over the last year. Sulfur dioxide air quality levels dropped 35 percent over the 10 years and decreased three percent over the last year. Ambient ozone levels dropped 16 percent over the long term, but increased five percent from 1986 to 1987. Nitrogen dioxide levels decreased 12 percent over the 10 years and showed no change in the last year. Annual average particulate (dirt, dust, soot) levels dropped 21 percent over the long term, but showed a two-percent increase between 1986 and 1987.

Psychosocial problems of donor heart recipients adversely affecting quality of life.  

PubMed

Heart transplantation has become an accepted therapy for patients suffering from terminal heart disease for whom neither standard forms of medication nor the usual surgery are of any benefit. Although results regarding postoperative quantity and quality of life are encouraging, it must not be overlooked that the patient and his family face, and have to overcome, profound psychosocial problems. The main stressors were identified in interviews with 47 heart transplant patients. The main preoperative problems were: the way of being informed about the diagnosis, the waiting period for transplantation, anguishing doubts about the decision to have a transplant, being a body without heart ('zombie'), guilt and shame regarding the donor, the reactions of others. Postoperatively the patients have to cope with: re-entering social systems, reactions of friends, neighbours and colleagues, rejection episodes, death of a fellow patient, the need to redesign family life. All the problems reported by the patients interviewed are discussed regarding their psychosocial implications, and hints are given on how to minimize them. PMID:1299462

Family Caregiver Social Problem-Solving Abilities and Adjustment to Caring for a Relative with Vision Loss  

PubMed Central

Purpose To examine the prevalence of persons at risk for depression among family caregivers of visually impaired persons and the extent to which social problem-solving abilities are associated with caregiver depressive symptomatology and life satisfaction. Methods Family caregivers were defined as adults who accompanied their adult relative to an appointment at a low-vision rehabilitation clinic and self-identified themselves as the primary family caregiver responsible for providing some form of assistance for their relative due to vision impairment. Demographic variables, depressive symptoms, life satisfaction, caregiver burden, and social problem-solving abilities were assessed in caregivers. The patient’s visual acuity and depressive symptoms and their relationship to the caregiver’s depressive symptoms and life satisfaction were also examined. Results Ninety-six family caregivers were enrolled. Of those, 35.4% were identified as at risk for depression. Among caregivers, dysfunctional or ineffective social problem-solving abilities were significantly associated with greater depressive symptomatology and decreased life satisfaction after adjustment for caregiver burden and demographic and medical variables for both the caregiver and the visually impaired patient. Problem orientation or motivation to solving problems was also significantly associated with caregiver depression and satisfaction with life. Conclusions A substantial number of caregivers of visually impaired adults experience psychosocial distress, particularly among those who possess poor social problem-solving abilities. These results underscore the need for routine screening and treatment of emotional distress among individuals caring for relatives with vision impairments. Future research should examine the extent to which psychosocial interventions targeting caregiver social problem-solving skills may be useful not only in improving caregiver quality of life but also in subsequently enhancing rehabilitation outcomes for the visually impaired care recipient.

Mood and health-related quality of life among pediatric patients with heart failure.  

PubMed

Adult patients with heart failure (HF) commonly experience depression, with morbid and mortal consequences. However, mood disorders in pediatric patients with HF are poorly understood. This study examined mood and health-related quality of life (HRQOL) in children with HF and compared them cross-sectionally with those of healthy control subjects and heart transplant (Htx) recipients with good heart function. The 62 participants in this study were divided into three groups: HF subjects (n = 15), Htx subjects (n = 23), and healthy control subjects (n = 24). The HF subjects all had chronic HF with a left ventricular ejection fraction lower than 35 %. All the participants completed the Mini-Mental State Examination (MMSE), the Childhood Depression Inventory (CDI), and the Pediatric Quality-of-Life Inventory Cardiac Module (PedsQL CM). Overall, the MMSE scores and CDI subscale scores were similar for all the groups. The HF and Htx participants scored similarly on the PedsQL CM subscales for HRQOL, treatment anxiety, perceived physical appearance, cognitive function, and communication. However, the HF group had a significantly lower HRQOL related to heart problems and treatment than the Htx group. The prevalence of depression among children with HF is not as high as reported in the adult HF literature. However, certain aspects of HRQOL experienced by pediatric HF patients still suffer, especially those related to heart problems and treatment. Health-related QOL tended to be better for the Htx participants than for the HF participants. Exploring developmental and psychosocial outcomes is critical for patients with HF, especially because it has an impact on vital developmental, academic, and social outcomes. PMID:22956059

Proxy Evaluation of Health-Related Quality of Life  

PubMed Central

Proxy assessment of health-related quality of life (HRQL) may be sought to substitute for, or to complement, patient self-assessment. The viewpoint from which the proxy is asked to assess the patient is a subtle yet important aspect of proxy assessment. Proxy assessments can be elicited by asking a proxy to assess the patient as they think the patient would respond (ie, proxy-patient perspective) or for the proxy to provide their own perspective on the patient’s HRQL (ie, proxy-proxy perspective). In this article, we introduce a framework for differentiating between and understanding HRQL assessments according to rater viewpoint. The difference between patient self-assessment and the proxy-patient perspective is defined as the inter-rater gap, whereas the difference between the proxy-patient and proxy-proxy perspective is described as the intra-proxy gap. The inter-rater gap represents the difference between patient self-assessed HRQL and the proxy ability to comprehend the patient view. The extent to which the proxy-proxy perspective is informative will depend upon the proxy’s ability to provide reinforcing or complementary information, ie, represented by the intra-proxy gap, on the HRQL of the patient. We refer to the framework to emphasize the importance of delineating between proxy perspectives in study design and HRQL measurement and to guide inquiries into the validity and interpretation of the meaningfulness of the proxy HRQL assessments from each viewpoint. Future research and use of proxy raters of HRQL in clinical trials, population health monitoring, resource allocation, and clinical management can be informed by explicit consideration of the suggested framework.

Coffee consumption and health-related quality of life.  

PubMed

BACKGROUND AND AIMS: Understanding the effect of coffee on health-related quality of life (HRQL) would contribute to explain the mechanisms of the long-term effect of coffee on health. The aim of this study was to examine the association between coffee consumption and HRQL. METHODS: Cross-sectional study conducted in 2008-2010 among 11,423 individuals representative of the Spanish population aged ?18 years. Habitual coffee and food consumption was assessed with a validated diet history. HRQL was measured using the Spanish version of the SF-12 questionnaire. The analyses were performed using linear regression and adjusted for the main confounders. RESULTS: Among men, no association was found between coffee consumption and the physical and mental composite summaries (PCS and MCS) of the SF-12. Among women, compared to those who did not consume coffee, habitual coffee drinkers showed similar scores on the PCS [beta coefficients (p value) for 1, 2, 3, and ?4 cups/day: 0.49 (0.20), 0.62 (0.21), 0.50 (0.45), and 0.36 (0.59)]; but slightly better scores on the MCS [beta (p value): 1.58 (<0.001), 1.58 (0.004), 0.80 (0.31), and 1.22 (0.10)]. These results reflect mostly the consumption of non-filtered caffeinated coffee. Tea consumption and total caffeine intake did not show an association with HRQL. CONCLUSION: We found no evidence of an adverse effect of coffee on HRQL.

The weak positive association of coffee with the MCS found among women needs further confirmation. PMID:23622779

Some problems related to the forming of blade blanks by high-speed ram extrusion  

NASA Astrophysics Data System (ADS)

A high-speed ram extrusion process for the production of turbine blades is described, and some problems associated with the process are examined. The problems discussed relate to the rebound and the repeat impact of the tooling, the hydraulic hammer effect in oil lines, and insufficient durability of the dies. Methods of overcoming these problems are discussed with particular reference to the extrusion of 120-220-mm long blades of EI961ISh steel.

Child-related disagreements, verbal aggression, and children's internalizing and externalizing behavior problems.  

PubMed

Dual-income parents (N = 122 couples) with an oldest child 18-60 months of age completed the Child-Rearing Disagreements Scale (E. N. Jouriles et al., 1991), the Child Behavior Checklist (T. M. Achenbach & L. A. Rescorla, 2000), and the Verbal Aggression subscale of the Conflicts and Problem-Solving Scale (P. K. Kerig, 1996). Replicating the results of E. N. Jouriles et al. (1991) and extending these findings to daughters and fathers, the authors found links between child-related disagreements and parental ratings of child behavior problems in this low-risk sample. There were no links between fathers' reports of verbal aggression and child behavior problems. Among mothers, however, use of verbal aggression mediated the link between child-related disagreements and ratings of sons' internalizing problems. Verbal aggression did not moderate the link between child-related disagreements and child behavior problems for either mothers or for fathers. PMID:15982101

Comparison of perceptions of oral health-related quality of life in adolescents affected with ectodermal dysplasias relative to caregivers  

PubMed Central

The objective of this study was to assess the perceived oral health-related quality of life (OHQoL) of adolescents affected with one of the ectodermal dysplasias (EDs). Data were collected from 2003 to 2007 in a cross-sectional study of a convenience sample of individuals affected by ED (n=35) using the Child Perceptions Questionnaire(CPQ11–14)for children and the Parent-Caregiver Perceptions Questionnaire (P-CPQ) for their caregivers. The main findings of this study were that individuals who were affected with ED in the older age group (15–19 years old) perceived more functional problems than younger individuals (11–14 years old) (p=0.04). Females with ED (n= 13) perceived more emotional problems than males (n=22; p=0.01). Although caregivers tended to report slightly higher OHQoL scores (indicating worse OHQoL), no significant differences were observed between children’s and parents’ total OHQoL and individual domains’ median scores (p>0.05). Thus, the perceptions of oral health and well-being may vary by age and gender for children who have ED. Caution is warranted concerning using parents as proxies for their children when assessing the child’s OHQoL.

Fuel cells provide a revenue-generating solution to power quality problems  

SciTech Connect

Electric power quality and reliability are becoming increasingly important as computers and microprocessors assume a larger role in commercial, health care and industrial buildings and processes. At the same time, constraints on transmission and distribution of power from central stations are making local areas vulnerable to low voltage, load addition limitations, power quality and power reliability problems. Many customers currently utilize some form of premium power in the form of standby generators and/or UPS systems. These include customers where continuous power is required because of health and safety or security reasons (hospitals, nursing homes, places of public assembly, air traffic control, military installations, telecommunications, etc.) These also include customers with industrial or commercial processes which can`t tolerance an interruption of power because of product loss or equipment damage. The paper discusses the use of the PC25 fuel cell power plant for backup and parallel power supplies for critical industrial applications. Several PC25 installations are described: the use of propane in a PC25; the use by rural cooperatives; and a demonstration of PC25 technology using landfill gas.

[Quality improvement in primary care. Financial incentives related to quality indicators in Europe].  

PubMed

Quality improvement in primary care has been an important issue worldwide for decades. Quality indicators are increasingly used quantitative tools for quality measurement. One of the possible motivational methods for doctors to provide better medical care is the implementation of financial incentives, however, there is no sufficient evidence to support or contradict their effect in quality improvement. Quality indicators and financial incentives are used in the primary care in more and more European countries. The authors provide a brief update on the primary care quality indicator systems of the United Kingdom, Hungary and other European countries, where financial incentives and quality indicators were introduced. There are eight countries where quality indicators linked to financial incentives are used which can influence the finances/salary of family physicians with a bonus of 1-25%. Reliable data are essential for quality indicators, although such data are lacking in primary care of most countries. Further, improvement of indicator systems should be based on broad professional consensus. PMID:23835354

Binge Drinking and Alcohol-Related Problems among U.S-Born Asian Americans  

PubMed Central

Binge drinking (five drinks or more in a 2-hour sitting for men, or four or more drinks in a 2-hour sitting for women) and alcohol-related problems are a growing problem among Asian American young adults. The current study examines the socio-cultural (i.e., generational status and ethnic identity) determinants of binge drinking and alcohol-related problems across U.S.-born, young adult, Asian American ethnic groups. Data were collected from 1,575 Asian American undergraduates from a public university in Southern California. Chinese Americans consisted of the largest Asian ethnicity in the study followed by Vietnamese, Filipino, Korean, South Asian, Japanese, Multi-Asian, and “other Asian American”. Participants completed a web-based assessment of binge drinking, alcohol-related problems, ethnic identity, descriptive norms (i.e., perceived peer drinking norms) and demographic information. An analysis of variance was used to determine potential gender and ethnic differences in binge drinking and alcohol-related problems. Negative binomial regression was selected to examine the relationship between the predictors and outcomes in our model. There were no gender differences between Asian American men and women in regards to binge drinking, however men reported more alcohol-related problems. Japanese Americans reported the highest number of binge drinking episodes and alcohol-related problems, followed by Filipino, and Multi-Asian Americans (e.g., Chinese and Korean). Living off-campus, higher scores in descriptive norms, Greek status, and belonging to the ethnic groups Japanese, Filipino, Multi-Asian, Korean, and South Asian increased the risk of engaging in binge drinking. Quantity of alcohol consumed, Greek status, gender, Filipino, South Asian “Other” Asian, and lower ethnic identity scores were related to alcohol-related problems. Using one of the largest samples collected to date on socio-cultural determinants and drinking among U.S.-born Asian American young adults, the findings highlight the significant variability in drinking patterns between Asian American ethnic groups.

High social anxiety is related to marijuana problems, yet the nature of this relation remains unclear. We examined relations between marijuana effect expectancies, social anxiety, and marijuana among undergraduates (N=337). Social anxiety was related positively to Negative Expectancies and negatively to Tension Reduction Expectancies. Among socially anxious individuals, greater belief that marijuana produces Cognitive and Behavioral Impairment was associated with greater marijuana use rates. Negative Expectancies mediated the social anxiety-marijuana problems link. These data provide new insight into problematic marijuana use among this high-risk group. PMID:18694625

Functional Ankle Instability and Health-Related Quality of Life  

PubMed Central

Context: To our knowledge, no authors have assessed health-related quality of life (HR-QOL) in participants with functional ankle instability (FAI). Furthermore, the relationships between measures of ankle functional limitation and HR-QOL are unknown. Objective: To use the Short Form–36v2 Health Survey (SF-36) to compare HR-QOL in participants with or without FAI and to determine whether HR-QOL was related to functional limitation. Design: Cross-sectional study. Setting: Sports medicine research laboratory. Patients or Other Participants: Sixty-eight participants with FAI (defined as at least 1 lateral ankle sprain and 1 episode of giveway per month) or without FAI were recruited (FAI group: n = 34, age = 25 ± 5 years, height = 1.71 ± 0.08 m, mass = 74.39 ± 12.78 kg, Cumberland Ankle Instability Tool score = 19.3 ± 4; uninjured [UI] group: n = 34, age = 23 ± 4 years, height = 1.69 ± 0.08 m, mass = 67.94 ± 11.27 kg, Cumberland Ankle Instability Tool score = 29.4 ± 1). Main Outcome Measure(s): All participants completed the SF-36 as a measure of HR-QOL and the Foot and Ankle Ability Measure (FAAM) and the FAAM Sport version (FAAMS) as assessments of functional limitation. To compare the FAI and UI groups, we calculated multiple analyses of variance followed by univariate tests. Additionally, we correlated the SF-36 summary component scale and domain scales with the FAAM and FAAMS scores. Results: Participants with FAI had lower scores on the SF-36 physical component summary (FAI = 54.4 ± 5.1, UI = 57.8 ± 3.7, P = .005), physical function domain scale (FAI = 54.5 ± 3.8, UI = 56.6 ± 1.2, P = .004), and bodily pain domain scale (FAI = 52.0 ± 6.7, UI = 58.5 ± 5.3, P < .005). Similarly, participants with FAI had lower scores on the FAAM (FAI = 93.7 ± 8.4, UI = 99.5 ± 1.4, P < .005) and FAAMS (FAI = 84.5 ± 8.4, UI = 99.8 ± 0.72, P < .005) than did the UI group. The FAAM score was correlated with the physical component summary scale (r = 0.42, P = .001) and the physical function domain scale (r = 0.61, P < .005). The FAAMS score was correlated with the physical function domain scale (r = 0.47, P < .005) and the vitality domain scale (r = 0.36, P = .002). Conclusions: Compared with UI participants, those with FAI had less HR-QOL and more functional limitations. Furthermore, positive correlations were found between HR-QOL and functional limitation measures. This suggests that ankle impairment may reduce overall HR-QOL.

Peer Victimization as a Mediator of the Relation between Facial Attractiveness and Internalizing Problems  

PubMed Central

This study examined the relations between facial attractiveness, peer victimization, and internalizing problems in early adolescence. We hypothesized that experiences of peer victimization would partially mediate the relationship between attractiveness and internalizing problems. Ratings of attractiveness were obtained from standardized photographs of participants (93 girls, 82 boys). Teachers provided information regarding peer victimization experiences in sixth grade, and seventh grade teachers assessed internalizing problems. Attractiveness was negatively correlated with victimization and internalizing problems. Experiences of peer victimization were positively correlated with internalizing problems. Structural equation modeling provided support for the hypothesized model of peer victimization partially mediating the relationship between attractiveness and internalizing problems. Implications for intervention programs and future research directions are discussed.

[The quality of information systems on violence-related deaths in Argentina and Brazil between 1990 and 2010].  

PubMed

Violence-related deaths are a public health issue by virtue of the magnitude of their impact on society and on the health services. A study of the descriptive temporal trend was conducted using the official national information systems of violence-related mortality in Argentina and Brazil for the period from 1990 to 2010. Indicators were created to evaluate information quality by sex, age, and cause of death. The results demonstrate a temporal trend of improvement in the quality of the information systems. This trend is repeated especially when violence-related deaths are analyzed, with a decrease in the number of records for violence-related death of undetermined intent; as well as a high percentage of firearm-related deaths of undetermined intent in Argentina. The analysis of the quality of information systems regarding violence-related deaths makes it possible to detect problems and orient actions in order to obtain better quality information and therefore permit improvement in the creation of preventive public policies.

Evaluating the satisfaction of immigrant women from a rural community regarding family functioning and health-related quality of life.  

PubMed

Transnational marriages in Taiwan are largely mediated by marriage brokers. The present study was conducted to evaluate the satisfaction of immigrant women with their family function and health-related quality of life in a rural township in southern Taiwan. Data were collected from January 1, 2006 to November 31, 2006, and 157 immigrants agreed to participate in the study, with a 79.3% response rate. A structured questionnaire was used for data collection. The interviewers also collected information on the immigrants' and husbands' demographics, self-reported mental conditions, family function using a Family APGAR questionnaire (Adaptability, Partnership, Growth, Affection, and Resolve), and health-related quality of life. Marriage arranged through a marriage broker and having emotional distress were factors that were strongly associated with lower Family APGAR scores. Based on multiple regression models, higher Family APGAR scores were more positively related to vitality and mental health scales. Self-reported mental conditions, including feeling economic distress, emotional distress, loneliness, and having sleep problems, were negatively associated with most scales of the health-related quality of life. Female migrants' mental health was significantly related to their health-related quality of life. These findings suggest that migrant women must be educated regarding the importance of mental health by physicians and hygiene authorities in Taiwan. PMID:23517512

Health-related quality of life in adult survivors after paediatric allo-SCT.  

PubMed

Fifty-three adults who had received SCT as children responded to questionnaires on health-related quality of life (HRQoL) (Swedish HRQoL survey (SWED-QUAL)), sense of coherence (SOC), anxiety and depression (HAD) and a health and symptom inventory. Late effects were classified following the Common Terminology Criteria for Adverse Events (CTCAE) v. 3.0. HRQoL was below norm in 9 of 13 SWED-QUAL domains. Poorest domains (P<0.001) were satisfaction with physical health, general health, partner relations and sexual function, whereas emotional wellbeing and satisfaction with family life were on par with the norm. Older age, time elapsed post-SCT and fewer self-reported symptoms correlated with better HRQoL. Unfavourable late effect scores had no or limited impact, whereas age at SCT or TBI did not adversely affect HRQoL. Most subjects were well subjectively and objectively, whereas 24% had more complicated late effects. The median Karnofsky score was 90, 13% of subjects having scores below 80. In total, 53% reported pain, whereas 42.5% had memory and concentration problems. Anxiety and/or depression, reported by 35%, were associated with lower HRQoL and SOC ratings. Overall, 55% reported infertility and expressed difficulty with this. To conclude, childhood SCT did not negatively affect overall health for most of these adult long-term survivors, although poorer HRQoL with psychological and cognitive problems are common.

[Differences in seed kernel quality and related enzyme activities of different quality type peanut cultivars].  

PubMed

Abstract: Taking high-protein peanut cultivar KB008, high-fat peanut cultivar Hual7 (H17), and high-oleic acid/linoleic acid (O/L) peanut cultivar Nongda818 as test materials, a field experiment was conducted in 2010 and 2011 to study the differences in the contents of protein, fat, and their components of the seed kernels, and the differences in the activities of the carbon and nitrogen metabolism enzymes related to the quality synthesis in the blades. As compared with that of H17 and Nongda818, the seed kernel of KB008 had significantly higher protein content but significantly lower soluble sugar content and O/L ratio, and the contents of the amino acid components, especially glutamic acid and lysine, in the seed kernel of KB008 were significantly higher. During the whole growth period, the activities of nitrate reductase (NR) , glutamine. synthetase (GS), glutamate dehydrogenase (GDH), glutamate synthase (GOGAT), and glutamate pyruvate transaminase (GPT) in the blades of the three cultivars were in the order of KB008>H17> Nongda818. At pod setting stage, the activities of PEPCase and RuBPCase in the blades of the three cultivars were ranked as KB008>H17> Nongda818. The higher PEPCase and RuBPCase activities of KB008 facilitated the protein synthesis and accumulation. The sucrose synthase (SS) activity in the blades was in the order of H17 > Nongda818 >KB008. The sucrose phosphate synthase (SPS) activity of KB008' s blades was significantly lower than that of the other two cultivars, while the SPS activity of H17' s blades was still higher even in the 60 days after anthesis, suggesting that the higher activities of SS and SPS in the blades were in favor of the fat formation in peanut seed kernel.

Quality related minimization of acrylamide formation--an integrated approach.  

PubMed

An integrated approach is described with respect to acrylamide minimization in heated foodstuffs. All relevant variables have to be considered and the main focus is on maintaining the expected product quality. The role of the processes at the interface between product and heating medium during processing is characterized for the case of frying operations. Examples of parameters influencing these processes with respect to minimizing acrylamide and maintaining product quality (e.g. brown color) are described. First, the local distribution of acrylamide in a French fries type model food was investigated. Lowering water activity at the surface of French fries before frying contributes to a reduction of acrylamide without lowering product quality. Both pre-drying of the potato sticks before frying and an increasing of salt concentration at the product surface by coating with a salt solution showed positive effects. Additionally, it was demonstrated by simulation that combined effects of these measurements may enable a reduction of up to 80% in the acrylamide content. PMID:16438311

Health-related quality of life outcomes after cholecystectomy  

PubMed Central

Gallbladder diseases are very common in developed countries. Complicated gallstone disease represents the most frequent of biliary disorders for which surgery is regularly advocated. As regards, cholecystectomy represents a common abdominal surgical intervention; it can be performed as either an elective intervention or emergency surgery, in the case of gangrene, perforation, peritonitis or sepsis. Nowadays, the laparoscopic approach is preferred over open laparotomy. Globally, numerous cholecystectomies are performed daily; however, little evidence exists regarding assessment of post-surgical quality of life (QOL) following these interventions. To assess post-cholecystectomy QOL, in fact, documentation of high quality care has been subject to extended discussions, and the use of patient-reported outcome satisfaction for quality improvement has been advocated for several years. However, there has been little research published regarding QOL outcomes following cholecystectomy; in addition, much of the current literature lacks systematic data on patient-centered outcomes. Then, although several tools have been used to measure QOL after cholecystectomy, difficulty remains in selecting meaningful parameters in order to obtain reproducible data to reflect postoperative QOL. The aim of this study was to review the impact of surgery for gallbladder diseases on QOL. This review includes Medline searches of current literature on QOL following cholecystectomy. Most studies demonstrated that symptomatic patients profited more from surgery than patients receiving an elective intervention. Thus, the gain in QOL depends on the general conditions before surgery, and patients without symptoms profit less or may even have a reduction in QOL.

Symmetry, reduction and relative equilibria of a rigid body in the J2 problem  

NASA Astrophysics Data System (ADS)

The J2 problem is an important problem in celestial mechanics, orbital dynamics and orbital design of spacecraft, as non-spherical mass distribution of the celestial body is taken into account. In this paper, the J2 problem is generalized to the motion of a rigid body in a J2 gravitational field. The relative equilibria are studied by using geometric mechanics. A Poisson reduction process is carried out by means of the symmetry. Non-canonical Hamiltonian structure and equations of motion of the reduced system are obtained. The basic geometrical properties of the relative equilibria are given through some analyses on the equilibrium conditions. Then we restrict to the zeroth and second-order approximations of the gravitational potential. Under these approximations, the existence and detailed properties of the relative equilibria are investigated. The orbit-rotation coupling of the rigid body is discussed. It is found that under the second-order approximation, there exists a classical type of relative equilibria except when the rigid body is near the surface of the central body and the central body is very elongated. Another non-classical type of relative equilibria can exist when the central body is elongated enough and has a low average density. The non-classical type of relative equilibria in our paper is distinct from the non-Lagrangian relative equilibria in the spherically-simplified Full Two Body Problem, which cannot exist under the second-order approximation. Our results also extend the previous results on the classical type of relative equilibria in the spherically-simplified Full Two Body Problem by taking into account the oblateness of the primary body. The results on relative equilibria are useful for studies on the motion of many natural satellites, whose motion are close to the relative equilibria.

Substance-related Problems and Treatment among MSM and Other Men in Chicago  

PubMed Central

This study compares a sample of urban MSM with a general population sample of men in the same city on self-reported problems with substance use indicative of dependence, and history of substance use treatment. Both samples were randomly selected using multistage probability methods. All participants completed Audio Computer-Assisted Self-Interviews (ACASI), including questions on substance use, problems related to substance use experienced in the past 12 months, and substance treatment. Problem use of alcohol, marijuana, and cocaine did not differ between samples. Compared to men in the general population sample, MSM were significantly more likely to experience problems related to the use of sedatives, tranquilizers, or prescription pain relievers. Among MSM, history of substance treatment was associated with a positive HIV test, and treatment usually preceded HIV diagnosis. Research is needed on effective methods for integrating HIV prevention for MSM into substance treatment settings, including physician-administered buprenorphine treatment for opiate addiction.

The effect of diagnosis with HIV infection on health-related quality of Life.  

PubMed

We sought to understand how diagnosis with HIV affects health-related quality of life. We assessed health-related quality of life using utility-based measures in a Department of Veterans Affairs (VA) clinic and a University-based clinic. Respondents assessed health-related quality of life regarding their current health, and retrospectively assessed their health 1 month prior to and 2 months after diagnosis with HIV infection. Sixty-six patients completed the study. The overall mean utilities for health 1 month before and 2 months after diagnosis were 0.87 (standard error 0.037), and 0.80 (0.043) (p<0.005 by rank sign test), but the effect of diagnosis differed between the two clinics, with a substantial decrease in the university clinic and a small non-significant decrease in the VA clinic. The overall mean utility for current health was 0.85 (0.034), assessed on average 7.5 years after diagnosis. When asked directly whether diagnosis of HIV decreased health-related quality of life, 47% agreed, but 35% stated that HIV diagnosis positively affected health-related quality of life. Diagnosis with HIV decreased health-related quality of life at 2 months on average, but this effect diminished over time, and differed among patient populations. Years after diagnosis, although half of the patients believed that diagnosis reduced health-related quality of life, one-third reported improved health-related quality of life. PMID:16411032

Substance-related health problems during rave parties in The Netherlands (1997-2008).  

PubMed

The objective of this study was to describe a 12-year (1997-2008) observation of substance-related incidents occurring at rave parties in the Netherlands, including length of visits to first-aid stations, substances used, and severity of the incidents. During rave parties, specifically trained medical and paramedical personnel staffed first aid stations. Visitors were diagnosed and treated, and their data were recorded using standardized methods. During the 12-year period with 249 rave parties involving about 3,800,000 visitors, 27,897 people visited a first aid station, of whom 10,100 reported having a substance-related problem. The mean age of these people was 22.3+/-5.4 years; 52.4% of them were male. Most (66.7%) substance-related problems were associated with ecstasy or alcohol use or both. Among 10,100 substance-related cases, 515 required professional medical care, and 16 of these cases were life threatening. People with a substance-related problem stayed 20 min at the first aid station, which was significantly longer than the 5 min that those without a substance-related health problem stayed. These unique data from the Netherlands identify a variety of acute health problems related to the use of alcohol, amphetamines, cannabis, cocaine, ecstasy, and GHB. Although most problems were minor, people using GHB more often required professional medical care those using the other substances. We recommended adherence to harm and risk reduction policy, and the use of first aid stations with specially trained staff for both minor and serious incidents. PMID:22216332

Comparing Health-Related Quality of Life of Cancer Patients under Chemotherapy and of Their Caregivers  

PubMed Central

Introduction. Cancer is a major disorder physically and psychologically affecting both patients and their caregivers. In this study, health-related quality of life (HRQoL) of patient-caregiver dyads during the period of chemotherapy was assessed. Material and Methods. Two hundred twenty-two cancer patient-caregiver dyads were enrolled in the study, which was conducted from October 2008 to March 2009. HRQoL was evaluated with EQ-5D. Results. The mean age of the sample was 57.4 and 48.9 for patients and caregivers, respectively. The EQ-5D descriptive system indicates that female patients more frequently experience anxiety and depression than male patients. Male and higher-education caregivers had higher VAS scores, while demographic factors did not seem to influence patients' HRQoL. Anxiety and depression of caregivers were correlated with patients' problems in self-care and usual activities. Conclusions. Quality of life is highly influenced during the period of chemotherapy for both patients and caregivers and is often under reported. Interventions that can improve HRQoL, especially in the domain of mental health for both cancer patients and their caregivers, need to be implemented.

Mexico City air quality research initiative. Volume 2, Problem definition, background, and summary of prior research  

SciTech Connect

Air pollution in Mexico City has increased along with the growth of the city, the movement of its population, and the growth of employment created by industry. The main cause of pollution in the city is energy consumption. Therefore, it is necessary to take into account the city`s economic development and its prospects when considering the technological relationships between well-being and energy consumption. Air pollution in the city from dust and other particles suspended in the air is an old problem. However, pollution as we know it today began about 50 years ago with the growth of industry, transportation, and population. The level of well-being attained in Mexico City implies a high energy use that necessarily affects the valley`s natural air quality. However, the pollution has grown so fast that the City must act urgently on three fronts: first, following a comprehensive strategy, transform the economic foundation of the city with nonpolluting activities to replace the old industries, second, halt pollution growth through the development of better technologies; and third, use better fuels, emission controls, and protection of wooded areas.

Inferring the Relative Quality of Reanalysis Data from a Historical Reforecast Using a Vorticity Equation Model  

NASA Astrophysics Data System (ADS)

The improvement of numerical weather prediction models in recent decades has led to a measurable decrease in forecast error, for instance as quantified by the 500-hPa geopotential height anomaly correlation. This improvement can be attributed in part to the refinements in the numerical architecture and the representation of physical processes in the model. It is more difficult to attribute the reduction in forecast error to improvements in the accuracy of the models' initial conditions, not least because of the complexity of the data assimilation process. As a contribution to this problem that will also be pedagogically useful, a reforecast experiment was conducted using a simple regional vorticity equation model for the 500-hPa flow over North America. This model is comparable in complexity to the Charney-Fjörtoft-von Neumann model used for the first numerical weather prediction experiment in 1949. Six-hourly predictions are made out to 36 hours for the period from 1948-2010, using the NCEP Reanalysis dataset for the initial conditions. Because initialization is trivial for this "filtered" model, one can clearly attribute the change in forecast skill to the changing quality of the initial state. The choice of the 500 hPa level is relevant since it will reflect the effect of the significant change in the density of upper-air observations from the mid- to late 20th Century. As an important byproduct of this exercise, a trend of improved forecast over time will imply an improved relative quality of the reanalysis data for the mid-troposphere. Therefore, the experiment serves two purposes of studying the forecast error and checking the quality of the reanalysis. An analysis of selected cases indicates that the predictions made for the 21st century have smaller errors compared to those made for the 1950s. A comprehensive analysis for the whole set of forecast is underway and the outcome will be discussed.

The Solution of Groundwater Quality Management Problems with a Nonconvex Feasible Region Using a Cutting Plane Optimization Technique  

NASA Astrophysics Data System (ADS)

In groundwater quality management problems the concentration constraints have a nonlinear behavior which may be described either as a convex or a nonconvex function. Therefore the feasible region, which is defined as the intersection of all of these constraints, can be either a convex or a nonconvex set. A review of existing optimization algorithms for the solution of the groundwater quality management problem indicates that the majority of them have an inability to determine a global optimum when nonconvexity occurs. In an earlier paper that appeared in this journal [Karatzas and Finder, 1993], the outer approximation method, a global optimization technique, was presented for the solution of groundwater management problems with convex constraints. The problem was formulated to minimize a concave objective function over a compact convex set of constraints. In the present study the same concept is applied to problems with nonconvex constraints. While the main concept of the current approach remains the same as that in our earlier study, there is a significant difference in the determination of the cutting hyperplane. The nonconvexity of the domain requires a special approach to insure that the introduction of the cutting hyperplane does not eliminate any part of the nonconvex feasible region. In this work the theory of the developed algorithm is presented and subsequently applied to two groundwater quality problems. In the first example a hypothetical aquifer is considered to illustrate the performance of the methodology. In the second example a groundwater quality management problem in Woburn, Massachusetts, is solved. Results obtained are compared with those generated by MINOS 5.1.

The philosophy of health-related quality of life translation.  

PubMed

Conventional translation strategies are limited because they enshrine deficiencies of the original questionnaire and do not permit modifications that reflect differences in culture and values. An alternative philosophy would require a conceptual definition of what one wanted to measure and would allow flexibility in the methods to achieve this goal. If an investigator had considerable time and resources, he or she could replicate the process used to construct the original English language questionnaire. With very limited resources, he or she could still omit irrelevant items, include new items, and modify the wording of questions and response options. This new philosophy allows improvement in content and presentation, and moves away from the hegemony of the American middle-class outlook in quality of life questionnaires. PMID:8161980

Marijuana-related problems and social anxiety: the role of marijuana behaviors in social situations.  

PubMed

Individuals with elevated social anxiety appear particularly vulnerable to marijuana-related problems. In fact, individuals with social anxiety may be more likely to experience marijuana-related impairment than individuals with other types of anxiety. It is therefore important to determine whether constructs particularly relevant to socially anxious individuals play a role in the expression of marijuana-related problems in this vulnerable population. Given that both social avoidance and using marijuana to cope with negative affect broadly have been found to play a role in marijuana-related problems, the current study utilized a new measure designed to simultaneously assess social avoidance and using marijuana to cope in situations previously identified as anxiety-provoking among those with elevated social anxiety. The Marijuana Use to Cope with Social Anxiety Scale (MCSAS) assessed behaviors regarding 24 social situations: marijuana use to cope in social situations (MCSAS-Cope) and avoidance of social situations if marijuana was unavailable. In Study 1, we found preliminary support for the convergent and discriminant validity and internal consistency of the MCSAS scales. In Study 2, we examined if MCSAS scores were related to marijuana problems among those with (n = 44) and without (n = 44) clinically elevated social anxiety. Individuals with clinically meaningful social anxiety were more likely to use marijuana to cope in social situations and to avoid social situations if marijuana was unavailable. Of importance, MCSAS-Cope uniquely mediated the relationship between social anxiety group status and marijuana-related problems. Results highlight the importance of contextual factors in assessing marijuana-related behaviors among high-risk populations. PMID:22004129

Curiosity killed the cocktail? Curiosity, sensation seeking, and alcohol-related problems in college women.  

PubMed

Curiosity, composed of two factors: exploration and absorption, has been previously associated with life satisfaction, life meaningfulness, and enhanced positive affect. It also shares some overlap with sensation seeking, which has been linked to alcohol use and other addictive behaviors. The present research explored the association between curiosity and college women's problematic drinking in the context of sensation seeking. Participants (79 women) completed questionnaires measuring curiosity, sensation seeking, alcohol consumption, and consequences related to alcohol consumption. A zero-inflated negative binomial model indicated that curiosity and sensation seeking accounted for unique variance in alcohol-related problems after controlling for drinking. The curiosity factors had opposing relationships to alcohol-related problems: higher scores on absorption were associated with more alcohol-related problems whereas higher scores on exploration were associated with fewer alcohol-related problems. Should findings be replicated, the curiosity factors may represent additional prevention and intervention targets. Future directions for research about curiosity and drinking and for the inclusion of positive psychology constructs in addictive behaviors research are discussed. PMID:20080358

Patient-reported outcome measures for sleep disorders and related problems: clinical and research applications.  

PubMed

Patients with sleep disorders are most concerned with the impact of these diseases on their quality of life. Patient-reported outcome (PRO) measurement tools, which assess aspects of a patient's health status that come directly from the patient, are well suited to evaluate quality of life related to sleep disorders. Although PRO data are subjective, they can be quantified, evaluated for reliability and reproducibility, and used to answer questions of clinical and research importance. This article reviews various PRO measure tools used for sleep disorders in clinical and research settings. These instruments may play a role in screening, diagnosis, and monitoring of various sleep disorders. PMID:23732593

Injury-related medical care utilization in a problem drinking population.  

PubMed Central

BACKGROUND. Population-based data on the overall risk of injury among problem drinkers are extremely limited. METHODS. We conducted an eight-year study of injury-related medical care utilization for a group of problem drinkers (n = 3 729) enrolled in the health insurance plan of a large manufacturing firm with plants in a number of midwestern states. A comparison non-problem drinking cohort matched on age, gender, and number of years of enrollment with the same company plan was also utilized. RESULTS. Problem drinkers utilized injury-related medical care at a rate 1.6 times that of the comparison group and experienced injury-related medical care costs which were three times as high. Increased risks were found for both men and women and for all ages studied. CONCLUSIONS. This study is one of the few to examine the overall incidence of fatal and non-fatal injuries among a large population of problem drinkers and provides evidence that higher medical care costs are associated with chronic alcohol use.

Some applications of the moving finite element method to fluid flow and related problems. [PWR; BWR  

SciTech Connect

The Moving Finite Element (MFE) method is applied to one-dimensional, nonlinear wave type partial differential equations which are characteristics of fluid dynamic and related flow phenomena problems. These equation systems tend to be difficult to solve because their transient solutions exhibit a spacial stiffness property, i.e., they represent physical phenomena of widely disparate length scales which must be resolved simultaneously. With the MFE method the node points automatically move (in theory) to optimal locations giving a much better approximation than can be obtained with fixed mesh methods (with a reasonable number of nodes) and with significantly reduced artificial viscosity or diffusion content. Three applications are considered. In order of increasing complexity they are: (1) a thermal quench problem, (2) an underwater explosion problem, and (3) a gas dynamics shock tube problem. The results are briefly shown.

Disparities in Alcohol-related Problems among White, Black and Hispanic Americans  

PubMed Central

Background This study assesses racial/ethnic disparities in negative social consequences of drinking and alcohol dependence symptoms among white, black and Hispanic Americans. We examine whether and how disparities relate to heavy alcohol consumption and pattern, and the extent to which social disadvantage (poverty, unfair treatment, and racial/ethnic stigma) accounts for observed disparities. Methods We analyzed data from the 2005 U.S. National Alcohol Survey, an RDD telephone survey conducted with adults ages 18 and older in the 50 states and the District of Columbia (N=6,919). Given large racial/ethnic differences in abstinence rates, core analyses were restricted to current drinkers (N=4,080). Logistic regression was used to assess disparities in alcohol-related problems at three levels of heavy drinking, measured using a composite variable incorporating frequency of heavy episodic drinking, frequency of drunkenness, and maximum amount consumed in a single day. A mediational approach was used to assess the role of social disadvantage. Results African American and Hispanic drinkers were significantly more likely than white drinkers to report social consequences of drinking and alcohol dependence symptoms. Even after adjusting for differences in heavy drinking and demographic characteristics, disparities in problems remained. The racial/ethnic gap in alcohol problems was greatest among those reporting little or no heavy drinking, and gradually diminished to nonsignificance at the highest level of heavy drinking. Social disadvantage, particularly in the form of racial/ethnic stigma, appeared to contribute to racial/ethnic differences in problems. Conclusions These findings suggest that to eliminate racial/ethnic disparities in alcohol-related problems, public health efforts must do more than reduce heavy drinking. Future research should address the possibility of drink size underestimation, identify the particular types of problems that disproportionately affect racial/ethnic minorities, and investigate social and cultural determinants of such problems.

Problems with Using the Normal Distribution - and Ways to Improve Quality and Efficiency of Data Analysis  

PubMed Central

Background The Gaussian or normal distribution is the most established model to characterize quantitative variation of original data. Accordingly, data are summarized using the arithmetic mean and the standard deviation, by ± SD, or with the standard error of the mean, ± SEM. This, together with corresponding bars in graphical displays has become the standard to characterize variation. Methodology/Principal Findings Here we question the adequacy of this characterization, and of the model. The published literature provides numerous examples for which such descriptions appear inappropriate because, based on the “95% range check”, their distributions are obviously skewed. In these cases, the symmetric characterization is a poor description and may trigger wrong conclusions. To solve the problem, it is enlightening to regard causes of variation. Multiplicative causes are by far more important than additive ones, in general, and benefit from a multiplicative (or log-) normal approach. Fortunately, quite similar to the normal, the log-normal distribution can now be handled easily and characterized at the level of the original data with the help of both, a new sign, x/, times-divide, and notation. Analogous to ± SD, it connects the multiplicative (or geometric) mean * and the multiplicative standard deviation s* in the form * x/s*, that is advantageous and recommended. Conclusions/Significance The corresponding shift from the symmetric to the asymmetric view will substantially increase both, recognition of data distributions, and interpretation quality. It will allow for savings in sample size that can be considerable. Moreover, this is in line with ethical responsibility. Adequate models will improve concepts and theories, and provide deeper insight into science and life.

Social Inequalities and Gender Differences in the Experience of Alcohol-Related Problems  

PubMed Central

Aims: To examine the influence of country-level characteristics and individual socio-economic status (SES) on individual alcohol-related consequences. Methods: Data from 42,655 men and women collected by cross-sectional surveys in 25 countries of the Gender, Alcohol and Culture: An International Study study were used. The individual SES was measured by the highest attained educational level. Alcohol-related consequences were defined as the self-report of at least one internal or one external consequence in the last year. The relationship between individuals’ education and alcohol-related consequences was examined by meta-analysis. In a second step, the individual level data and country data were combined in multilevel models. As country-level indicators, we used the purchasing power parity of the gross national income (GNI), the Gini coefficient and the Gender Gap Index. Results: Lower educated men and women were more likely to report consequences than higher educated men and women even after controlling for drinking patterns. For men, this relation was significant for both internal and external problems. For women, it was only significant for external problems. The GNI was significantly associated with reporting external consequences for men such that in lower income countries men were more likely to report social problems. Conclusion: The fact that problems accrue more quickly for lower educated persons even if they drink in the same manner can be linked to the social or environmental dimension surrounding problems. That is, those of fewer resources are less protected from the experience of a problem or the impact of a stressful life event.

Cognitive biases in individuals with mild to borderline intellectual disability and alcohol use-related problems.  

PubMed

The primary aim of the present pilot study was to examine cognitive biases in individuals with mild to borderline ID and alcohol use-related problems. Participants (N=57) performed the approach avoidance task, picture rating task and visual dot probe task, which was combined with eye-tracking methodology. They were admitted to a forensic setting and were all abstinent and undergoing treatment at the time of testing. Three groups were formed based on the severity of alcohol use-related problems as measured by the AUDIT. In line with the expectations, no differences were found between participants based on the severity of their alcohol use-related problems. In addition, three groups were formed based on IQ to assess the relationship between IQ and the strength of the cognitive biases. There were also no differences between individuals with mild or borderline ID and individuals with (below) average IQ on any of the variables. It is concluded that computer tasks such as these can be used in individuals with mild to borderline ID. As the results suggest no influence of IQ on the strength of cognitive biases, this study opens up new opportunities for future research on the application of measuring cognitive biases in screening, diagnosing and treating individuals with mild to borderline ID and alcohol use-related problems.

Comparison of patient evaluations of health care quality in relation to WHO measures of achievement in 12 European countries.  

PubMed Central

OBJECTIVES: To gain insight into similarities and differences in patient evaluations of quality of primary care across 12 European countries and to correlate patient evaluations with WHO health system performance measures (for example, responsiveness) of these countries. METHODS: Patient evaluations were derived from a series of Quote (QUality of care Through patients' Eyes) instruments designed to measure the quality of primary care. Various research groups provided a total sample of 5133 patients from 12 countries: Belarus, Denmark, Finland, Greece, Ireland, Israel, Italy, the Netherlands, Norway, Portugal, United Kingdom, and Ukraine. Intraclass correlations of 10 Quote items were calculated to measure differences between countries. The world health report 2000 - Health systems: improving performance performance measures in the same countries were correlated with mean Quote scores. FINDINGS: Intra-class correlation coefficients ranged from low to very high, which indicated little variation between countries in some respects (for example, primary care providers have a good understanding of patients' problems in all countries) and large variation in other respects (for example, with respect to prescription of medication and communication between primary care providers). Most correlations between mean Quote scores per country and WHO performance measures were positive. The highest correlation (0.86) was between the primary care provider's understanding of patients' problems and responsiveness according to WHO. CONCLUSIONS: Patient evaluations of the quality of primary care showed large differences across countries and related positively to WHO's performance measures of health care systems.

Job Dissatisfaction as a Contributor to Stress-related Mental Health Problems among Japanese Civil Servants.  

PubMed

Although studies on the association of job dissatisfaction with mental health have been conducted in the past, few studies have dealt with the complicated links connecting job stress, job dissatisfaction, and stress-related illness. This study seeks to determine how job dissatisfaction is linked to common mental health issues. This study surveyed 3,172 civil servants (2,233 men and 939 women) in 1998, taking poor mental functioning, fatigue, and sleep disturbance as stress-related mental health problems. We examine how psychosocial risk factors at work and job dissatisfaction are associated independently with poor mental functioning, fatigue, and sleep disturbance after adjustment for other known risk factors, and how job dissatisfaction contributes to change in the degree of association between psychosocial risk factors at work and mental health problems. In general, psychosocial risk factors were independently associated with mental health problems. When adjusted for job dissatisfaction, not only was job satisfaction independently associated with mental health problems but it was also found that the association of psychosocial risk factors with mental health problems declined. Our results suggest that, although longitudinal research is necessary, attitudes toward satisfaction at work can potentially decrease the negative effects of psychosocial risk factors at work on mental health.

A new combined stable and dispersion relation preserving compact scheme for non-periodic problems  

NASA Astrophysics Data System (ADS)

A new compact scheme is presented for computing wave propagation problems and Navier-Stokes equation. A combined compact difference scheme is developed for non-periodic problems (called NCCD henceforth) that simultaneously evaluates first and second derivatives, improving an existing combined compact difference (CCD) scheme. Following the methodologies in Sengupta et al. [T.K. Sengupta, S.K. Sircar, A. Dipankar, High accuracy schemes for DNS and acoustics, J. Sci. Comput. 26 (2) (2006) 151-193], stability and dispersion relation preservation (DRP) property analysis is performed here for general CCD schemes for the first time, emphasizing their utility in uni- and bi-directional wave propagation problems - that is relevant to acoustic wave propagation problems. We highlight: (a) specific points in parameter space those give rise to least phase and dispersion errors for non-periodic wave problems; (b) the solution error of CCD/NCCD schemes in solving Stommel Ocean model (an elliptic p.d.e.) and (c) the effectiveness of the NCCD scheme in solving Navier-Stokes equation for the benchmark lid-driven cavity problem at high Reynolds numbers, showing that the present method is capable of providing very accurate solution using far fewer points as compared to existing solutions in the literature.

On the existence of the relative equilibria of a rigid body in the J 2 problem  

NASA Astrophysics Data System (ADS)

The motion of a point mass in the J 2 problem has been generalized to that of a rigid body in a J 2 gravity field for new high-precision applications in the celestial mechanics and astrodynamics. Unlike the original J 2 problem, the gravitational orbit-rotation coupling of the rigid body is considered in the generalized problem. The existence and properties of both the classical and non-classical relative equilibria of the rigid body are investigated in more details in the present paper based on our previous results. We nondimensionalize the system by the characteristic time and length to make the study more general. Through the study, it is found that the classical relative equilibria can always exist in the real physical situation. Numerical results suggest that the non-classical relative equilibria only can exist in the case of a negative J 2, i.e., the central body is elongated; they cannot exist in the case of a positive J 2 when the central body is oblate. In the case of a negative J 2, the effect of the orbit-rotation coupling of the rigid body on the existence of the non-classical relative equilibria can be positive or negative, which depends on the values of J 2 and the angular velocity ? e . The bifurcation from the classical relative equilibria, at which the non-classical relative equilibria appear, has been shown with different parameters of the system. Our results here have given more details of the relative equilibria than our previous paper, in which the existence conditions of the relative equilibria are derived and primarily studied. Our results have also extended the previous results on the relative equilibria of a rigid body in a central gravity field by taking into account the oblateness of the central body.

Assessing the status of research on violence-related problems among youth.  

PubMed

Presents results of a systematic review of abstracts on studies related to violence and youth in an effort to identify areas that have received little attention in the psychological literature and to present recommendations for future research. A total of 1,168 empirical articles on violence-related problems in youth were identified by a PsycINFO (American Psychological Association, 1980-1999) search. These articles were then classified in a multidimensional grid, allowing for comparisons among different types of articles. A review of abstracts from these articles indicated that most of the research activity has been descriptive (e.g., reviewing correlates or predictors of violence involvement) or assessment related (e.g., evaluating specific measures). Fewer articles examined the treatment or prevention of violence-related problems among youth. Further, the majority of studies pertained to direct exposure to violence (as a victim or perpetrator), with very few studies looking at the effects of witnessing violence, knowing individuals exposed to violence, or being exposed to violence through the media. Comparing treatment and prevention articles, we found that the least empirical attention was paid to the prevention of violence-related problems in youth, and not a single study was identified through this search that sought to examine the prevention of youth witnessing violence. Implications for future research agendas are discussed. PMID:11393916

Longitudinal Examination of Physical and Relational Aggression as Precursors to Later Problem Behaviors in Adolescents  

PubMed Central

Research has addressed the consequences of being a victim of physical and relational aggression, but less so the consequences of being an aggressor during adolescence. Consequently, relatively little is known about the extent to which aggression in early adolescence increases the risk of later aggression and other psychosocial problems. This study involves a representative sample of 7th- and 9th-grade students from Washington State (N = 1,942). Students were surveyed upon recruitment, and then again 1 and 2 years later, to learn about ongoing behavior problems, substance use, depression, and self-harm behaviors. Surveys also included measures of several hypothesized promotive factors: attachment to family, school commitment, and academic achievement. Findings suggest that being physically and/or relationally aggressive in Grades 7–9 increases the risk of aggression and possibly other problem behaviors after accounting for age, gender, race, and a prior measures of each outcome. Independent promotive effects were observed in most analyses, although family attachment appeared a less robust predictor overall. Implications for prevention include reducing aggression and enhancing promotive influences to lessen the risk of ongoing problems.

Solving China's environmental problems: policy options from the Working Group on Environment in U.S.-China Relations.  

PubMed

This article describes the main themes, funding needs, and policy options of the Working Group on the Environment in US-China Relations that was created in November 1996. Meetings are chaired by members of the Council of Foreign Relations and the Carnegie Endowment for International Peace. The 40+ member Working Group is coordinated by the Environmental Change and Security Project and the Woodrow Wilson Center's Asia Program. It offers a forum for discussion of environmental and foreign policy concerns. The aims are to identify important environmental and sustainable development issues related to US and Chinese interests; to develop creative strategies for government and nongovernment projects between the US and China; and to discuss strategies for using environmental issues for building improved relations between countries. Monthly meetings focus on energy issues, water quantity and quality, funds for environmental protection, and biodiversity issues. The group meetings emphasize the themes of multilateral cooperation, local Chinese environmental issues of significance to the US, and obstacles to cooperation on US-led projects within China. Improved relations may be achieved by articulation of a coherent China policy with explicit goals and guidelines, provision of funding, and linking local environmental problems with global ones. The US should support private business in marketing environmental technology and assist in the development of policy changes in the energy and water sectors in China. China needs improved irrigation techniques and comprehensive watershed management plans. PMID:12321722

Health related quality of life across the perinatal period among Australian women.  

PubMed

AIMS AND OBJECTIVES: To investigate the significant features in health-related quality of life and to examine the changes over time during the perinatal period. BACKGROUND: Health-related quality of life during the perinatal period is significant for women. Screening or surveillance during the perinatal period is inconsistent and often not part of continued assessment. DESIGN: Prospective. METHODS: Setting involved antenatal clinics at three public hospitals in metropolitan Brisbane, Australia. A total of 363 participants out of a cohort of 605 women completed all items of the Short Form-12 Health Survey in late pregnancy and again at 6 and 12 weeks postpartum. RESULTS: There was a significant difference across the three perinatal time periods in all the health-related quality-of-life subscales. Significant improvements were noted from late pregnancy to 6 weeks following childbirth and again at 12 weeks particularly in physical health, role physical, bodily pain, vitality, role emotional and mental health. Even when confounding variables such as maternal ages, partner status, parity, delivery type and ethnicity were introduced, significant improvements were noted. Maternal distress significantly related to almost all quality-of-life factors over time even when all possible confounding factors were controlled. CONCLUSION: Significant changes occur in health-related quality of life across the perinatal period. All dimensions of health-related quality of life except for social functioning and maternal distress showed marked improvement following childbirth. During this period, maternal distress was negatively related to health-related quality of life. RELEVANCE TO CLINICAL PRACTICE: Nurses need to be mindful of the broader view of health as encompassed in health-related quality-of-life measures and the potential these have for alerting health professionals when providing care. More rigorous health assessment for mothers at risk is useful so that appropriate support and follow-up can be given. PMID:23750859

Vision-specific health-related quality of life: content areas for nursing home residents.  

PubMed

Nursing home residents have a high prevalence of remediable visual impairment and blindness. Future research on the effectiveness of providing eye care to nursing home residents will need to include a vision-targeted health-related quality of life (HRQOL) instrument appropriate for this population. The purpose of this study was to identify the core content areas for such an instrument. In-depth interviews on vision-related issues were conducted with 40 residents. Interviews were audio-taped, transcribed, and coded using a standardized protocol. Binocular distance and near visual acuity were assessed using the resident's 'walking around' correction to examine whether one vision-specific HRQOL measure could address the needs of residents with 'good' and 'poor' vision. Overall 1070 vision-related comments were identified. Residents mentioned 315 problem comments that were grouped into 13 categories, including ocular symptoms (18% of comments), reading (15%), general vision (13%), psychological distress (12%), and activities of daily living (ADLs) (7%). Compared to published data on vision-specific content areas most relevant to community based persons, nursing home residents focused more on ocular symptoms and basic ADLs, with no mention of issues related to driving, home care, and finances. The majority of categories mentioned did not differ on the proportion of comments made- by those with 'good' and 'poor' visual acuity, suggesting that one vision-specific HRQOL instrument would be appropriate for residents with varying levels of visual acuity. Future work will focus on developing a vision-specific HRQOL instrument for nursing home residents. PMID:12113392

Internalized heterosexism, alcohol use, and alcohol-related problems among lesbians and gay men.  

PubMed

Research regarding internalized heterosexism in relation to alcohol use and alcohol-related problems has suffered from methodological problems. Moreover, the results of the research have been mixed. The purpose of the current study was to examine internalized heterosexism in relation to alcohol use and alcohol-related problems among a sample of 335 lesbians and gay men recruited through lesbian and gay events, listserves, and friendship networks. Females completed the Lesbian Internalized Homophobia Scale [Szymanski, D. M., & Chung, Y. B. (2001). The internalized homophobia scale for lesbians: A rational/theoretical approach. Journal of Homosexuality, 41(2), 37-52.]; males completed the Internalized Homonegativity Inventory [Mayfield, W. (2001). The development of an internalized homonegativity inventory for gay men.

Parotid gland sparing IMRT for head and neck cancer improves xerostomia related quality of life  

PubMed Central

Background and purpose To assess the impact of intensity modulated radiotherapy (IMRT) versus conventional radiation on late xerostomia and Quality of Life aspects in head and neck cancer patients. Patients and nethods Questionnaires on xerostomia in rest and during meals were sent to all patients treated between January 1999 and December 2003 with a T1-4, N0-2 M0 head and neck cancer, with parotid gland sparing IMRT or conventional bilateral neck irradiation to a dose of at least 60 Gy, who were progression free and had no disseminated disease (n = 192). Overall response was 85% (n = 163); 97% in the IMRT group (n = 75) and 77% in the control group (n = 88) the median follow-up was 2.6 years. The prevalence of complaints was compared between the two groups, correcting for all relevant factors at multivariate ordinal regression analysis. Results Patients treated with IMRT reported significantly less difficulty transporting and swallowing their food and needed less water for a dry mouth during day, night and meals. They also experienced fewer problems with speech and eating in public. Laryngeal cancer patients in general had fewer complaints than oropharynx cancer patients but both groups benefited from IMRT. Within the IMRT group the xerostomia scores were better for those patients with a mean parotid dose to the "spared" parotid below 26 Gy. Conclusion Parotid gland sparing IMRT for head and neck cancer patients improves xerostomia related quality of life compared to conventional radiation both in rest and during meals. Laryngeal cancer patients had fewer complaints but benefited equally compared to oropharyngeal cancer patients from IMRT.

Assessment of groundwater quality of the Tatlicay aquifer and relation to the adjacent evaporitic formations (Cankiri, Turkey).  

PubMed

One of the most important hydrogeologic problems in and adjacent areas of evaporitic formations is severe quality degradation of groundwaters. These kinds of groundwaters contain high content of dissolved solids and generally have some limitations for use. Tatlicay basin (north-central Turkey) is an example to effects of the evaporites on groundwater quality in the adjacent alluvium aquifer. Gypsum and anhydrites in the two evaporite formations (Bayindir and Bozkir) effect of the groundwater quality in the alluvium adversely, by dissolution of the evaporites by surface drainage and infiltration into the alluvium aquifer (widespread effect) and by infiltration of low quality gypsum springs (local effect) into the aquifer. Evaporitic formations significantly increased EC, TDS, Ca and SO(4) parameters in the alluvium aquifer in the central and downstream regions. EC has increased roughly from 500-800 to 1,700-2,000 ?S/cm, Ca has roughly increased from 3-4 to 10 meq/l, SO(4) has increased 0.5-1 to 11-12 meq/l. Consequently, three clusters were distinguished in the basin; (1) nonevaporitic waters in low TDS, Na, Ca, Mg, Cl and SO(4), (2) diluted waters in high TDS and relatively high Cl, moderate-relatively high Na, Ca, Mg, SO(4), (3) gypsum springs in highest TDS, Ca, SO(4), but moderate Mg and low Na, Cl.

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

PubMed

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. PMID:17618718

Health-related quality of life instruments and individual diagnosis - a new area of application  

PubMed Central

Objectives: Various health-related quality of life (HRQoL) instruments for children and adolescents have been developed and are applied in clinical and health economic studies with the research focus on the HRQoL of specific groups of responders, comparing these groups respectively. However, if HRQoL assessment aims to contribute on deciding upon a suitable individual treatment and the evaluation thereof, as well as to identify hidden morbidities, an individual diagnostic perspective is required. To date, the majority of HRQoL questionnaires for children and adolescents are not designed for individual diagnostic assessment and comparison. This paper aims to demonstrate that should a particular measurement tool meet specific psychometric requirements – an individual diagnostic assessment on mental health related problems is possible. We investigated whether or not the KIDSCREEN-27 HRQoL instrument for children and adolescents is able to detect mental health problems in general, provided we apply a principal component analysis (PCA) for summative scaling. Methods: The cross-sectional survey of the KIDSCREEN project was carried out in 13 European countries (AT, CH, CZ, DE, EL, ES, FR, HU, IE, NL, PL, SE, UK). The Rasch-scaled KIDSCREEN-27 test-data of 22,830 children and adolescents were analysed. To achieve a summative scaling PCA was performed on the correlation between the KIDSCREEN-27 scores. The principal component (PC) values were estimated and used to score the respondents. The reliability and diagnostic quality of this scoring was examined. Results: The first PC accounted for 58.28% of the entire variance within the KIDSCREEN-27 scores. All KIDSCREEN scales loaded high on the first PC. The reliability of the linear combination of KIDSCREEN-27 scores with the PC-values was rr=.94 and thus above the threshold for individual comparison. This value was higher than the values for the original single KIDSCREEN-27 scores (rr=.78-.84). The receiver operating characteristic curve (ROC) was calculated whilst screening for respondents with a mental health problem in general (Strengths and Difficulties Questionnaire). The area under the ROC (AuC) was .80 and statistically significant lower than the AuC issued after a logistic regression analysis employing the 5 original KIDSCREEN-27 scores (AuC=.83). However, according to international conventions, both AuCs denote a ”good” discrimination. Conclusion: Specifically for the KIDSCREEN-27 the results show that the application of a specific scoring algorithm leads to fulfil pre-specified demands of high reliability. The applied scoring approach leads to a good discrimination of the measurement, thus enabling to detect a mental health problem in general using the HRQoL test-data. The presented approach can enhance the usability and range of application of HRQoL measurement.

Relations between shyness-sensitivity and internalizing problems in Chinese children: moderating effects of academic achievement.  

PubMed

Shy-sensitive children are likely to develop adjustment problems in today's urban China as the country has evolved into an increasingly competitive, market-oriented society. The main purpose of this one-year longitudinal study was to examine the moderating effects of academic achievement on relations between shyness-sensitivity and later internalizing problems in Chinese children. A sample of 1171 school-age children (591 boys, 580 girls) in China, initially at the age of 9 years, participated in the study. Data on shyness, academic achievement, and internalizing problems were collected from multiple sources including peer evaluations, teacher ratings, self-reports, and school records. It was found that shyness positively and uniquely predicted later loneliness, depression, and teacher-rated internalizing problems, with the stability effect controlled, for low-achieving children, but not for high-achieving children. The results indicate that, consistent with the stress buffering model, academic achievement may be a buffering factor that serves to protect shy-sensitive children from developing psychological problems.

Gender Differences in 16-Year Trends in Assault- and Police-Related Problems Due to Drinking  

PubMed Central

This study examined the frequency and predictors of physical assault and having trouble with the police due to drinking over 16 years among women and men who, at baseline, were untreated for their alcohol use disorder. Predictors examined were the personal characteristics of impulsivity, self-efficacy, and problem-solving and emotional-discharge coping, as well as outpatient treatment and Alcoholics Anonymous (AA) participation. Women and men were similar on rates of perpetrating assault due to drinking, but men were more likely to have had trouble with the police due to drinking. Respondents who, at baseline, were more impulsive and relied more on emotional discharge coping, and less on problem-solving coping, assaulted others more frequently during the first year of follow-up. Similarly, less problem-solving coping at baseline was related to having had trouble with the police more often at one and 16 years due to drinking. The association between impulsivity and more frequent assault was stronger for women, whereas associations of self-efficacy and problem-solving coping with less frequent assault and police trouble were stronger for men. Participation in AA was also associated with a lower likelihood of having trouble with the police at one year, especially for men. Interventions aimed at decreasing impulsivity and emotional discharge coping, and bolstering self-efficacy and problem-solving coping, during substance abuse treatment, and encouragement to become involved in AA, may be helpful in reducing assaultive and other illegal behaviors.

Postoperative recovery and its association with health-related quality of life among day surgery patients  

PubMed Central

Background Day surgery holds advantages for both the patient and the health care organization. However, recovery beyond the first postoperative week and following different types of surgery has not been explored to any greater degree. The current aims were to prospectively describe postoperative recovery and health-related quality of life among different groups of day surgery patients and to explore the association between postoperative recovery and health-related quality of life 30 days after discharge. Methods A consecutive sample of 607 adult day surgery patients undergoing orthopaedic, gynaecological or general surgery was included. Postoperative recovery was assessed on days 1, 7 and 14 using the Swedish Post-discharge Surgery Recovery scale and the Quality of Recovery-23 scale. The EQ-5D was used to assess health-related quality of life preoperatively and 30 days following discharge. A repeated measure ANOVA was conducted to evaluate postoperative recovery from day 1 to day 14 and between different surgical groups. Hierarchical multiple linear regression models were used to explore the association between postoperative recovery and health-related quality of life. Results Postoperative recovery improved from day 1 to 14 in all surgical groups (p<0.001). The orthopaedic patients had lower postoperative recovery on day 14 compared to the general and the gynaecological patients (p<0.001). Health-related quality of life was lower among orthopaedic patients (p<0.001), even if significant improvements over time were seen in all groups. Recovery on day 7 was associated with health-related quality of life 30 days after the day surgery (p<0.05). Conclusion Particularly orthopaedic day surgical patients seem to favour a closer follow-up in order to support recovery and thereby also positively influence health-related quality of life.

Health-related quality of life and its determinants in children with a congenital diaphragmatic hernia  

PubMed Central

Background The development of new therapeutics has led to progress in the early management of congenital diaphragmatic hernia (CDH) in pediatric intensive care units (PICU). Little is known about the impact on the quality of life (QoL) of children and their family. The aim of this study was to assess the impact of CDH treated according to the most recent concepts and methods outlined above on child survivors’ QoL and their parents’ QoL. Patients and methods This study incorporated a cross-sectional design performed in two PICU (Marseille, France). Families of CDH survivors born between 1999 and 2008 were eligible. The following data were recorded: socio-demographics, antenatal history and delivery, initial hospitalization history. Self-reported data were collected by mail, including current clinical problems of the children (13-symptom list), children’s QoL (Kidscreen-27 questionnaire), and parents’ QoL (Short-Form 36 questionnaire). Children’s QoL score was compared with controls and QoL of survivors of childhood leukemia. Parent’s QoL was compared with controls. Non-parametric statistics were employed. Results Forty-two families agreed to participate and questionnaires were completed by 32 of them. Twenty-one children had a current clinical problems related to CDH. All the QoL scores of CHD survivors were significantly lower compared with controls. The physical well-being dimension was significantly higher for CHD survivors compared with survivors of childhood leukemia. Gastro-esophageal reflux at discharge, antenatal diagnosis, length of stay in the PICU, and neuropsychological and respiratory issues significantly impacted QoL scores of children. The parents of CHD survivors had significantly poorer score in emotional role dimension compared with controls. Conclusion The impact of CDH on QoL seems to be important and must be understood by clinicians who treat these children and their parents.
