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

Relations of parenting quality, interparental conflict, and overnights with mental health problems of children in divorcing families with high legal conflict.  

PubMed

The current study examined the associations between child mental health problems and the quality of maternal and paternal parenting, and how these associations were moderated by three contextual factors: quality of parenting by the other parent, interparental conflict, and the number of overnights parents had with the child. Data for the current study came from a sample of divorcing families who are in high legal conflict over developing or maintaining a parenting plan following divorce. Analyses revealed that the associations between child mental health problems and positive maternal and paternal parenting were moderated by the quality of parenting provided by the other parent and by the number of overnights children spent with parents, but not by the level of interparental conflict. When parenting by the other parent and number of overnights were considered together in the same model, only number of overnights moderated the relations between parenting and child-behavior problems. The results support the proposition that the well-being of children in high-conflict divorcing families is better when they spend adequate time with at least one parent who provides high-quality parenting.

Evaluating health-related quality of life and priority health problems in patients with prostate cancer: a strategy for defining the role of the advanced practice nurse.  

PubMed

A framework for the introduction and evaluation of APN roles emphasizes the importance of a systematic approach to role development based on the assessment of patient health needs. This study determined the health-related quality of life (HRQL) of patients with prostate cancer. The most frequent and severe patient health problems and their perceptions of priority health problems were identified and compared across five patient groups as a strategy to inform the supportive care role of the advanced oncology nurse for patients with advanced prostate cancer. The study found that the majority of men with early stage and advanced hormone sensitive prostate cancer can expect to enjoy good quality of life for several years following diagnosis. These two patient groups have common priority needs for improving their health related to sexual function, urinary frequency, urinary incontinence, and physical activity. Both groups may benefit from an advanced practice nursing (APN) role that can provide episodic supportive care for health problems occurring at different treatment stages. Conversely, it was found that men with advanced hormone refractory prostate cancer experience significantly poorer HRQL and have multiple severe health problems. These patients also have different priority needs including problems related to pain, fatigue, and decreased physical activity. Because of this, the focus of supportive care programs and interventions in advanced prostate cancer will differ for those with hormone refractory disease. They may benefit more from an APN role that can provide ongoing rather than episodic supportive care to assess and manage the multiple, new, and worsening health problems associated with progressive disease.

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. PMID:23486934

Air quality in Beijing and its transition from coal burning caused problems to traffic exhaust related pollution  

SciTech Connect

Air pollution in Beijing is characterized by coal smoke for a long time because of energy structure highly dependence on coal consumption. SO{sub 2}, TSP, and NO{sub x} ambient concentration are kept in high levels, which exceed the guideline of WHO and National Air Quality Standard NAQS. The trend of SO{sub 2} change is relative stable, its annual average concentration fluctuates around 100 g/m{sup 3} since 1981. TSP show a fast decrease before 1986 and keep a slow decrease afterwards approaching the level of about 300 g/m{sup 3}. NO{sub x} concentration increases continuously all the time. Since 1993, NO{sub x} concentration exceeds SO{sub 2} to be the important pollutant next to TSP in Beijing, especially in summertime and traffic busy areas. As the consequence of NO{sub x} fast increase, the ozone pollution level is elevated greatly since 1980s. Several integrated field measurements were conducted to study the characteristics of photochemical smog and its formation mechanism. Hourly averaged ozone concentration usually exceeded the NAQS (80 ppb) in April to October. The O{sub 3} formation is very sensitive to NO{sub x} concentration because of the high NMHC/NO{sub x} ratio. In recent years, high O{sub 3} concentration is observed in early Spring and photochemical smog pollution is getting more and more severe with dramatically increase of vehicles in downtown Beijing. It is predicted that O{sub 3} pollution will be expected to enhance greatly in next 20 years under the development plan of future urban transportation system and increment of vehicles, even in the case that control strategies suggested by municipal government are undertaken. So more strengthen control strategies in Beijing are needed.

Prospective observational cohort study of Health Related Quality of Life (HRQOL), chronic foot problems and their determinants in gout: a research protocol  

PubMed Central

Background Gout is the commonest inflammatory arthritis affecting around 1.4% of adults in Europe. It is predominantly managed in primary care and classically affects the joints of the foot, particularly the first metatarsophalangeal joint. Gout related factors (including disease characteristics and treatment) as well as comorbid chronic disease are associated with poor Health Related Quality of Life (HRQOL) yet to date there is limited evidence concerning gout in a community setting. Existing epidemiological studies are limited by their cross-sectional design, selection of secondary care patients with atypical disease and the use of generic tools to measure HRQOL. This 3?year primary care-based prospective observational cohort study will describe the spectrum of HRQOL in community dwelling patients with gout, associated factors, predictors of poor outcome, and prevalence and incidence of foot problems in gout patients. Methods Adults aged???18?years diagnosed with gout or prescribed colchicine or allopurinol in the preceding 2?years will be identified through Read codes and mailed a series of self-completion postal questionnaires over a 3-year period. Consenting participants will have their general practice medical records reviewed. Discussion This is the first prospective cohort study of HRQOL in patients with gout in primary care in the UK. The combination of survey data and medical record review will allow an in-depth understanding of factors that are associated with and lead to poor HRQOL and foot problems in gout. Identification of these factors will improve the management of this prevalent, yet under-treated, condition in primary care. PMID:23148573

The relative effects of maternal and child problems on the quality of attachment: a meta-analysis of attachment in clinical samples.  

PubMed

In this meta-analysis of 34 clinical studies on attachment the hypothesis is tested that maternal problems such as mental illness lead to more deviating attachment classification distributions than child problems such as deafness. A correspondence analysis on 21 North American studies with normal subjects produced a baseline against which the clinical samples could be evaluated. Separate analyses were carried out on studies containing the traditional A, B, C classifications and on studies that also included the recently discovered D or A/C category. Results show that groups with a primary identification of maternal problems show attachment classification distributions highly divergent from the normal distributions, whereas groups with a primary identification of child problems show distributions that are similar to the distributions of normal samples. The introduction of the D or A/C classifications (about 15% in normal samples) reveals an overrepresentation of D or A/C in the child problem groups, but the resulting distribution still is much closer to the normal distributions compared to the samples with maternal problems. In clinical samples, the mother appears to play a more important role than the child in shaping the quality of the infant-mother attachment relationship. PMID:1387067

Problem to Address: Local Air Quality  

NASA Technical Reports Server (NTRS)

This presentation discusses the problem of local air quality as it is affected by modern aircraft engine exhaust and the objective of this workshop. It begins with a discussion on the nature and sources of particulates and aerosols. The problems, and the technical considerations of how to regulate the aircraft emissions, are reviewed. There is no local (i.e., state or county) regulations of the aircraft operations. Amongst the conclusions are: (1) there is an inadequate database of information regarding the emittants from aircrafts. (2) That data which does exist represents older engines and aircraft, it is not representative of the advanced and future fleet.

Background A proportion of people with mental health problems require longer term care in a psychiatric or social care institution. However, there are no internationally agreed quality standards for institutional care and no method to assess common care standards across countries. We aimed to identify the key components of institutional care for people with longer term mental health problems and the effectiveness of these components. Methods We undertook a systematic review of the literature using comprehensive search terms in 11 electronic databases and identified 12,182 titles. We viewed 550 abstracts, reviewed 223 papers and included 110 of these. A "critical interpretative synthesis" of the evidence was used to identify domains of institutional care that are key to service users' recovery. Results We identified eight domains of institutional care that were key to service users' recovery: living conditions; interventions for schizophrenia; physical health; restraint and seclusion; staff training and support; therapeutic relationship; autonomy and service user involvement; and clinical governance. Evidence was strongest for specific interventions for the treatment of schizophrenia (family psychoeducation, cognitive behavioural therapy (CBT) and vocational rehabilitation). Conclusion Institutions should, ideally, be community based, operate a flexible regime, maintain a low density of residents and maximise residents' privacy. For service users with a diagnosis of schizophrenia, specific interventions (CBT, family interventions involving psychoeducation, and supported employment) should be provided through integrated programmes. Restraint and seclusion should be avoided wherever possible and staff should have adequate training in de-escalation techniques. Regular staff supervision should be provided and this should support service user involvement in decision making and positive therapeutic relationships between staff and service users. There should be clear lines of clinical governance that ensure adherence to evidence-based guidelines and attention should be paid to service users' physical health through regular screening.

Correlations among improvements in urgency urinary incontinence, health-related quality of life, and perception of bladder-related problems in incontinent subjects with overactive bladder treated with tolterodine or placebo  

PubMed Central

Background Previous studies demonstrate that tolterodine extended release (ER) significantly improves urgency urinary incontinence (UUI) episodes. Instruments that measure patient-reported outcomes (PROs) provide additional information that is valuable for assessing whether clinical improvements are meaningful to the patient. This study determined the correlation of changes in bladder diary variables and other PROs in subjects with overactive bladder (OAB). Methods Subjects with OAB, urinary frequency, and UUI were treated with 4 mg once-daily tolterodine ER or placebo for 12 weeks. Subjects completed 7-day bladder diaries, the Patient Perception of Bladder Condition (PPBC), and the King's Health Questionnaire (KHQ) at baseline and week 12. Only subjects who reported at least some minor bladder-related problems at baseline (PPBC score ? 3) were included in this analysis. Results Reductions in UUI episodes per week were significantly greater in the tolterodine ER group (n = 500) compared with the placebo group (n = 487) at week 12 (-71% vs -33%, P < 0.0001). A significantly greater percentage of subjects in the tolterodine ER group reported improvement on the PPBC versus placebo (58% vs 45%, P < 0.0001), and 7 of 10 KHQ domains were significantly improved versus placebo (all P < 0.05). Significant correlations were found for median percentage changes in UUI episodes with changes in PPBC scores (r = 0.35,P < 0.0001) and the 7 improved KHQ domains (r = 0.16–0.32, P ? 0.0011). Changes in PPBC scores and all KHQ domains were significantly correlated (r = 0.13–0.38, P ? 0.009) in the tolterodine ER group. Correlations among endpoints in the placebo group were similar to those observed in the tolterodine ER group. Conclusion Improvement in UUI episodes after 12 weeks of treatment with tolterodine ER or placebo was correlated with improvements in patients' perception of their bladder-related problems and health-related quality of life. Correlations were moderate in magnitude but statistically significant, suggesting that PROs are important and relevant measures for evaluating OAB treatment. PMID:19226471

"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 authors identify machine learning of dominance relations and the applicable learning mechanisms. A study of learning dominance relations using learning by experimentation is described. This system has been able to learn dominance relations for the 0/1-knapsack problem, an inventory problem, the reliability-by-replication problem, the two-machine flow shop problem, a number of single-machine scheduling problems, and a two-machine scheduling problem. It is considered that the same methodology can be extended to learn dominance relations in general.

Exploring the relationship between work-related rumination, sleep quality, and work-related fatigue.  

PubMed

This study examined the association among three conceptualizations of work-related rumination (affective rumination, problem-solving pondering, and detachment) with sleep quality and work-related fatigue. It was hypothesized that affective rumination and poor sleep quality would be associated with increased fatigue and that problem-solving pondering and detachment would be associated with decreased fatigue. The mediating effect of sleep quality on the relationship between work-related rumination and fatigue was also tested. An online questionnaire was completed by a heterogeneous sample of 719 adult workers in diverse occupations. The following variables were entered as predictors in a regression model: affective rumination, problem-solving pondering, detachment, and sleep quality. The dependent variables were chronic work-related fatigue (CF) and acute work-related fatigue (AF). Affective rumination was the strongest predictor of increased CF and AF. Problem-solving pondering was a significant predictor of decreased CF and AF. Poor sleep quality was predictive of increased CF and AF. Detachment was significantly negatively predictive for AF. Sleep quality partially mediated the relationship between affective rumination and fatigue and between problem-solving pondering and fatigue. Work-related affective rumination appears more detrimental to an individual's ability to recover from work than problem-solving pondering. In the context of identifying mechanisms by which demands at work are translated into ill-health, this appears to be a key finding and suggests that it is the type of work-related rumination, not rumination per se, that is important.

Relative locality and the soccer ball problem  

E-print Network

We consider the behavior of macroscopic bodies within the framework of relative locality, which 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. These lead to the addition of non-linear terms to the energy-momentum relations and conservation laws, which are suppressed by powers of ratio between the energy E of the particles involved and the Planck mass M_P. 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_{macro} much larger than M_P. We show that this "soccer-ball problem" does not arise within the framework of relative locality, because the non-linear effects for the dynamics of a composite system with N elementary particles appear at most of order E_{macro}/ N M_...

Longitudinal effects of sibling relationship quality on adolescent problem behavior: a cross-ethnic comparison.  

PubMed

The aim of the present study was to examine whether adolescents of Moroccan and Dutch origin differ concerning sibling relationship quality and to examine whether the associations between quality of the sibling relationship and level and change in externalizing and internalizing problem behavior are comparable for Moroccan and Dutch adolescents. Five annual waves of questionnaire data on sibling support and conflict as well as externalizing problems, anxiety and depression were collected from 159 ethnic Moroccan adolescents (Mage = 13.3 years) and from 159 ethnic Dutch adolescents (Mage = 13.0 years). Our findings demonstrated significant mean level differences between the Moroccan and Dutch sample in sibling relationship quality, externalizing problems, and depression, with Moroccan adolescents reporting higher sibling relationship quality and less problem behavior. However, effects of sibling relationship quality on externalizing problems, anxiety, and depression were similar for the Moroccan and Dutch samples. Sibling support was not related to level of externalizing problems, nor to changes in externalizing problems, anxiety, and depression. Additionally, more sibling conflict was related to a higher starting level of and faster decreases in problem behaviors. Our results support the ethnic equivalence model, which holds that the influence of family relationships is similar for different ethnic groups. Moreover, sibling support and conflict affect both the level and the fluctuations in problem behavior over time in specific ethnic groups similarly. Implications for future studies and interventions are subsequently discussed. PMID:23978197

Recent materials problems relating to catastrophic balloon failures  

NASA Astrophysics Data System (ADS)

Balloons fabricated of thin polyethylene materials have provided relatively inexpensive and reliable scientific research platforms for approximately three decades. Reliability of the modern day balloon, as launched by the U.S.A. National Scientific Balloon Facility (NSBF), has been approximately 85%. Recent balloon failures, coupled with an increased occurrence of catastrophic failures, created grave concern over the integrity of the present balloon inventory of the U.S.A National Aeronautics and Space Administration (NASA). An investigative team was established by NASA to review the circumstances surrounding the catastrophic balloon failures, determine the cause and to make recommendations to correct the problem and to prevent its reoccurrence. The most probable cause of failure as determined by the investigation was the polyethylene balloon film, although the film had passed the established standard quality control measures of the film manufacturer. The approach, findings, and conclusions of the investigation are presented along with planned procedures to assure future quality balloon film for NASA balloons.

Giving travel advice to travellers visiting high-altitude destinations around the globe is daily routine in travel clinics. However, with the classical focus on vaccinations, traveller's diarrhoea, mosquito protection and malaria prophylaxis, altitude-related health problems are often neglected at counselling. The importance to communicate these problems when giving travel advice is impressively reflected by the high prevalence of altitude-related health problems among tourists visiting high-lying tourist destinations. This article aims at providing an overview of core aspects of acclimatization to altitude and prevention of altitude-related health problems and to exemplarily address practice-oriented problem destinations.

Coping and social problem solving correlates of asthma control and quality of life.  

PubMed

In a sample of adults with asthma receiving care and medication in an outpatient pulmonary clinic, this study tested for statistical associations between social problem-solving styles, asthma control, and asthma-related quality of life. These variables were measured cross sectionally as a first step toward more systematic application of social problem-solving frameworks in asthma self-management training. Recruitment occurred during pulmonology clinic service hours. Forty-four adults with physician-confirmed diagnosis of asthma provided data including age, gender, height, weight, race, income, and comorbid conditions. The Asthma Control Questionnaire, the Mini Asthma Quality of Life Questionnaire (Short Form), and peak expiratory force measures offered multiple views of asthma health at the time of the study. Maladaptive coping (impulsive and careless problem-solving styles) based on transactional stress models of health were assessed with the Social Problem-Solving Inventory-Revised: Short Form. Controlling for variance associated with gender, age, and income, individuals reporting higher impulsive-careless scores exhibited significantly lower scores on asthma control (? = 0.70, p = 0.001, confidence interval (CI) [0.37-1.04]) and lower asthma-related quality of life (? = 0.79, p = 0.017, CI [0.15-1.42]). These findings suggest that specific maladaptive problem-solving styles may uniquely contribute to asthma health burdens. Because problem-solving coping strategies are both measureable and teachable, behavioral interventions aimed at facilitating adaptive coping and problem solving could positively affect patient's asthma management and quality of life.

Quality improvement projects related to pediculosis management.  

PubMed

Concern about student absenteeism related to repeated pediculosis infestations and the consequent risk for unsuccessful school achievement led to a quality improvement program comprised of 6 projects. The goal was to identify effective nursing interventions for children and families incurring repeated infestations. One project addressed the prevalence of infestation, frequency of school exclusion, and duration of consequential lost school days. Affirmed were low contagion in classrooms and multiple social and emotional challenges in students having chronic infestations. From other projects, the importance of establishing effective relationships with parents, students, and school staff to work toward effective management outcomes was apparent. Also identified was the need to better match hair texture with the selection of a lice comb for effective mechanical removal of lice and nits. There is a need to replicate these projects with larger numbers of students in different geographic locations. It is important to have evidence-based information about the communicability and management strategies for pediculosis to contribute to sound treatment and policy formation. PMID:12017250

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. PMID:20674507

Computation of Transonic Nozzle Sound Transmission and Rotor Problems by the Dispersion-Relation-Preserving Scheme  

NASA Technical Reports Server (NTRS)

The transonic nozzle transmission problem and the open rotor noise radiation problem are solved computationally. Both are multiple length scales problems. For efficient and accurate numerical simulation, the multiple-size-mesh multiple-time-step Dispersion-Relation-Preserving scheme is used to calculate the time periodic solution. To ensure an accurate solution, high quality numerical boundary conditions are also needed. For the nozzle problem, a set of nonhomogeneous, outflow boundary conditions are required. The nonhomogeneous boundary conditions not only generate the incoming sound waves but also, at the same time, allow the reflected acoustic waves and entropy waves, if present, to exit the computation domain without reflection. For the open rotor problem, there is an apparent singularity at the axis of rotation. An analytic extension approach is developed to provide a high quality axis boundary treatment.

Quality analysis of the solution produced by dissection algorithms applied to the traveling salesman problem  

SciTech Connect

The aim of this paper is to analyze experimentally the quality of the solution obtained with dissection algorithms applied to the geometric Traveling Salesman Problem. Starting from Karp`s results. We apply a divide and conquer strategy, first dividing the plane into subregions where we calculate optimal subtours and then merging these subtours to obtain the final tour. The analysis is restricted to problem instances where points are uniformly distributed in the unit square. For relatively small sets of cities we analyze the quality of the solution by calculating the length of the optimal tour and by comparing it with our approximate solution. When the problem instance is too large we perform an asymptotical analysis estimating the length of the optimal tour. We apply the same dissection strategy also to classical heuristics by calculating approximate subtours and by comparing the results with the average quality of the heuristic. Our main result is the estimate of the rate of convergence of the approximate solution to the optimal solution as a function of the number of dissection steps, of the criterion used for the plane division and of the quality of the subtours. We have implemented our programs on MUSIC (MUlti Signal processor system with Intelligent Communication), a Single-Program-Multiple-Data parallel computer with distributed memory developed at the ETH Zurich.

Compact Formulations of the Steiner Traveling Salesman Problem and Related Problems  

E-print Network

The Steiner Traveling Salesman Problem (STSP) is a variant of the Traveling Salesman Problem (TSP) that is particularly suitable when dealing with sparse networks, such as road networks. The standard integer programming formulation of the STSP has an exponential number of constraints, just like the standard formulation of the TSP. On the other hand, there exist several known {\\em compact} formulations of the TSP, i.e., formulations with a polynomial number of both variables and constraints. In this paper, we show that some of these compact formulations can be adapted to the STSP. We also briefly discuss the adaptation of our formulations to some closely-related problems.

Some unsolved problems relating to noise in biological systems  

NASA Astrophysics Data System (ADS)

A faithful description of many biological processes requires us to take into account noise and fluctuations. Simplified stochastic models may help to shed light on the role of fluctuations in biological systems. Two kinds of theoretical problems for such simplified models are discussed in this paper. Firstly, I review approaches for calculating analytically the statistics of stochastic non-linear models of spontaneous neural activity. In particular, I discuss (i) interspike interval correlations in non-renewal neurons and (ii) the effect of synaptic short-term plasticity on neural signal transfer. Secondly, I discuss the more conceptual problem of how more detailed models are related to simplified models. I consider, as an example of an open problem of this kind, the relation between detailed models of coupled molecular motors and models of active Brownian motion.

The Differential Association between Change Request Qualities and Resistance, Problem Resolution, and Relationship Satisfaction  

PubMed Central

Although research supports the negative sequelae of the “demand-withdrawal” pattern, research is scant on the impact of “non-demanding” change requests (e.g., specific, increasing, and “we” requests). We hypothesize that such change requests will be associated with less partner withdrawal/resistance, better problem resolution, and greater relationship satisfaction. Seventy-two conversations between couples who were recruited through random digit dialing were coded for change request qualities. Results indicate that wife specific and “we” requests led to less husband resistance, and husband increasing and “we” requests led to less wife resistance. Greater percentages of wife and husband specific and “we” requests were related to better problem resolution in the conversation, and greater percentages of wife specific and “we” requests were related to greater wife satisfaction. Research and clinical implications are detailed. PMID:19685982

a Simplified Two-Body Problem in General Relativity  

NASA Astrophysics Data System (ADS)

General relativity, Einstein's theory of gravity, predicts a universe full of black holes and gravitational waves. The prospects of detecting gravitational waves from inspirals of compact astrophysical objects into supermassive black holes have made it highly important to analyze in detail the gravitational two-body problem. While the two-body problem in Newtonian gravity (the weak-field limit) has a well-defined compact analytic solution, the corresponding problem in general relativity (the strong-field regime) is very complex and cannot be solved analytically. In this paper, we propose to model the two-body problem in general relativity using the analytically solvable model of a ring of particles in orbit around a central black hole. We use our model to calculate the innermost stable circular orbit (ISCO) frequency which characterizes the two-body dynamics. Remarkably, our expression for the characteristic ISCO frequency through linear order in the ring's mass predicts with astonishing accuracy the actual value of this fundamental parameter.

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. PMID:21347000

Health Related Quality of Life and Influencing Factors among Welders  

PubMed Central

Background Occupational exposure to welding fumes is a serious occupational health problem all over the world. Welders are exposed to many occupational hazards; these hazards might cause some occupational diseases. The aim of the study was to assess the health related quality of life (HRQL) of electric welders in Shanghai China and explore influencing factors to HRQL of welders. Methods 301 male welders (without pneumoconiosis) and 305 non-dust male workers in Shanghai were enrolled in this study. Short Form-36 (SF-36) health survey questionnaires were applied in this cross-sectional study. Socio-demographic, working and health factors were also collected. Multiple stepwise regress analysis was used to identify significant factors related to the eight dimension scores. Results Six dimensions including role-physical (RP), bodily pain (BP), general health (GH), validity (VT), social function (SF), and mental health (MH) were significantly worse in welders compared to non-dust workers. Multiple stepwise regress analysis results show that native place, monthly income, quantity of children, drinking, sleep time, welding type, use of personal protective equipment (PPE), great events in life, and some symptoms including dizziness, discomfort of cervical vertebra, low back pain, cough and insomnia may be influencing factors for HRQL of welders. Among these factors, only sleep time and the use of PPE were salutary. Conclusions Some dimensions of HRQL of these welders have been affected. Enterprises which employ welders should take measures to protect the health of these people and improve their HRQL. PMID:25048102

Cauchy problems related to integrable deformations of pseudo differential operators  

NASA Astrophysics Data System (ADS)

In this paper we discuss the solvability of two Cauchy problems in the pseudo differential operators. The first is associated with a set of pseudo differential operators of negative order, the prominent example being the set of strict integral operator parts of the different powers of a solution of the KP hierarchy. We show that it can be solved, provided the setting possesses a compatibility completeness. In such a setting all solutions of the KP hierarchy are obtained by dressing with the solution of the related Cauchy problem. The second Cauchy problem is slightly more general and links up with a set of pseudo differential operators of order zero or less. The key example here is the collection of integral operator parts of the different powers of a solution of the strict KP hierarchy. This system is solvable as soon as exponential and compatibility completeness holds. Also under these circumstances, all solutions of the strict KP hierarchy are obtained by dressing with the solution of the corresponding Cauchy problem.

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. PMID:23477449

Tethered body problems and relative motion orbit determination  

NASA Technical Reports Server (NTRS)

Selected problems dealing with orbiting tethered body systems have been studied. In addition, a relative motion orbit determination program was developed. Results from these tasks are described and discussed. The expected tethered body motions were examined, analytically, to ascertain what influence would be played by the physical parameters of the tether, the gravity gradient and orbit eccentricity. After separating the motion modes these influences were determined; and, subsequently, the effects of oscillations and/or rotations, on tether force, were described. A study was undertaken, by examining tether motions, to see what type of control actions would be needed to accurately place a mass particle at a prescribed position relative to a main vehicle. Other applications for tethers were studied. Principally these were concerned with the producing of low-level gee forces by means of stabilized tether configurations; and, the initiation of free transfer trajectories from tether supported vehicle relative positions.

Stochastic partial differential equations in turbulence related problems  

NASA Technical Reports Server (NTRS)

The theory of stochastic partial differential equations (PDEs) and problems relating to turbulence are discussed by employing the theories of Brownian motion and diffusion in infinite dimensions, functional differential equations, and functional integration. Relevant results in probablistic analysis, especially Gaussian measures in function spaces and the theory of stochastic PDEs of Ito type, are taken into account. Linear stochastic PDEs are analyzed through linearized Navier-Stokes equations with a random forcing. Stochastic equations for waves in random media as well as model equations in turbulent transport theory are considered. Markovian models in fully developed turbulence are discussed from a stochastic equation viewpoint.

Quality comparison of websites related to developmental disabilities.  

PubMed

The Internet is commonly used to seek health-related information, but little is known about the quality of websites on developmental disabilities. Therefore, we sought to evaluate the characteristics and quality of websites located by searching ten common terms related to developmental disabilities and explore relations between website characteristics and website quality in order to make recommendations on ways to ensure locating good online information. We located 208 unique websites in our November 2012 US searches of Google and Bing. Two independent coders evaluated 10 characteristics of the websites and two different coders assessed the quality of the websites. From the 208 websites, 104 (50%) provided relevant information about the disability being searched. Of these 104 websites, those found to be of highest quality were least likely to be a sponsored result, contain advertisements, be from a for-profit company, and did contain references to peer-reviewed publications or had a top-level domain of .gov or .org. Individuals with developmental disabilities and their family members who choose to obtain disability-related information online should remain vigilant to ensure that they locate high-quality and accurate information and should not replace information obtained from health-care professionals and educational specialists with information found online.

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. PMID:23471477

Association between diet, social resources and oral health related quality of life in edentulous patients.  

PubMed

To assess whether there was an association between diet, oral health related quality of life and social resources in a population of older edentulous adults, and, to assess the impact of provision of new complete replacement dentures. This study was carried out at Cork University Dental Hospital in Ireland. In this prospective clinical study, 35 edentulous adults who requested new complete dentures completed pre-treatment questionnaires which included validated oral health status, social resources and nutritional assessment questionnaires. New dentures were provided and the impact of treatment on oral health related quality of life, diet and ability to chew food was assessed. Satisfaction with dentures and oral health related quality of life improved following provision of new dentures. However, food choice remained similar to pre-treatment choice, and subjects were rated as medium risk for poor nutritional status on the Mini Nutritional Assessment (MNA) score. Oral health related quality of life and diet were not correlated. Three quarters of the sample felt they had no nutritional problems. However, approximately 70% reported that they had changed their food choices because of dental problems and that financial cost was a barrier to dental treatment. Food selection among the group studied was not ideal, and not improved by the provision of new dentures. There was no association between diet and oral health related quality of life. Further research is needed to improve our understanding of the relationship between oral health and diet. PMID:16102073

This 6-month prospective study investigated the outcomes of foot surgery performed by Fellows of the Australian College of Podiatric Surgeons. The study recruited 140 patients who were treated for orthopedic, neurological, or integumentary diseases of the foot. The majority of subjects who underwent podiatric surgery experienced significant postoperative improvements in a range of health-related quality-of-life dimensions as measured by the disease-specific Foot Health Status Questionnaire (FHSQ) and the generic Short Form 36 (SF-36) questionnaire. Subjects reported a reduction in foot pain, increased levels of physical function, improved general foot health perception, and improved footwear-related quality of life. No significant adverse outcomes or unplanned re-admissions to the hospital were reported. This study demonstrates the advantage of assessing health-related quality of life as opposed to patient satisfaction. PMID:11319246

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

Relationships between undergraduates' argumentation skills, conceptual quality of problem solutions, and problem solving strategies in introductory physics  

NASA Astrophysics Data System (ADS)

This study explored the effects of alternative forms of argumentation on undergraduates' physics solutions in introductory calculus-based physics. A two-phase concurrent mixed methods design was employed to investigate relationships between undergraduates' written argumentation abilities, conceptual quality of problem solutions, as well as approaches and strategies for solving argumentative physics problems across multiple physics topics. Participants were assigned via stratified sampling to one of three conditions (control, guided construct, or guided evaluate) based on gender and pre-test scores on a conceptual instrument. The guided construct and guided evaluate groups received tasks and prompts drawn from literature to facilitate argument construction or evaluation. Using a multiple case study design, with each condition serving as a case, interviews were conducted consisting of a think-aloud problem solving session paired with a semi-structured interview. The analysis of problem solving strategies was guided by the theoretical framework on epistemic games adapted by Tuminaro and Redish (2007). This study provides empirical evidence that integration of written argumentation into physics problems can potentially improve the conceptual quality of solutions, expand their repertoire of problem solving strategies and show promise for addressing the gender gap in physics. The study suggests further avenues for research in this area and implications for designing and implementing argumentation tasks in introductory college physics.

Although combat-related posttraumatic stress disorder (PTSD) has been documented for military combatants, little is known about PTSD in noncombatants. Active-duty U.S. Air Force noncombatants (N = 5,367) completed a Post-Deployment Health Assessment upon return from combat zones in Iraq (n = 4,408) or a noncombat zone in Qatar (n = 959). Those deployed to Iraq were significantly more likely to report exposure to someone who was wounded or killed (20.8% vs. 6.3%), feeling in great danger of being killed at some point during deployment (18.9% vs. 3.5%), symptoms of PTSD (4.1% vs. 0.7%), and symptoms of major depression (9.9% vs. 5.4%). These findings suggest that deployment to a war zone is associated with increased mental health problems, even for noncombatants. PMID:21171127

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

Asymmetry in Keratoconus and Vision-Related Quality of Life  

PubMed Central

Purpose To examine the relation of increased ocular asymmetry over time on vision-related quality of life in keratoconus. Methods Subjects were in the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study and had complete data on a least one scale of the NEI VFQ and examination data at baseline and at least one follow-up visit. Three measures of disease asymmetry (visual acuity, corneal curvature, and refractive error) and better eye status were assessed. Multilevel models were fit to the data. Results Analyses were completed using 961 subjects. Six scales on the NEI VFQ had adequate variability to model (distance activity, driving, mental health, near activity, ocular pain, and role difficulties). Refractive error changes were not associated with statistically significant quality of life differences. Except for ocular pain, statistically significant, but not clinically meaningful, differences were found for visual acuity changes and corneal curvature changes. For a 0.1-unit logMAR visual acuity change, the quality of life scales decreased between 0.20 and 0.99 units. For a 1.00-D steepening of corneal curvature these decreases were on the order of 0.20 to 0.59 units. Changes related to asymmetry were small as well: decreases on the order of 0.20 to 0.38 units. Conclusions Increasing ocular asymmetry and decreases in visual acuity and corneal steepening in the better eye were associated with decreasing vision-related quality of life, though the magnitudes of the changes were not clinically meaningful. Of these two disease status indicators, the vision in the better eye had greater effect on vision-related quality of life. PMID:22825402

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).

Quality of Life in Cancer Patients and its Related Factors  

PubMed Central

Introduction: Despite the importance of quality of life (QOL) in outcomes of cancer pa-tients, there have been a few Iranian studies investigating the Iranian patients’ quality of life. The present study aimed to assess the cancer patients’ QOL and its related factors. Methods: This cross-sectional study conducted in Shahid Ghazi Tabatabaei Hospital affiliated to Tabriz University of Medical Sciences in 2009. The samples included 150 cancer patients aged more than 18 years who were aware of their own diagnosis. They were selected through convenient sampling method and European Organization for Research and Treatment of Cancer–Quality of life questionnaire (EORTC–QOL 30) were completed. Results: Our findings showed that 44.1% of the patients had moderate QOL. QOL had a significant correlation with the level of family support (p = 0.002). Conclusion: Many of cancer patients have a moderate QOL. However, confirmation of such finding requires further investigations.

eEurope 2002: Quality Criteria for Health related Websites  

PubMed Central

Background A number of organisations have begun to provide specific tools for searching, rating, and grading this information, while others have set up codes of conduct by which site providers can attest to their high quality services. The aim of such tools is to assist individuals to sift through the mountains of information available so as to be better able to discern valid and reliable messages from those which are misleading or inaccurate. Objective Recognising that European citizens are avid consumers of health related information on the internet and recognising that they are already using the types of rating system described above, the European Council at Feira on June 19-20 2000 supported an initiative within eEurope 2002 to develop a core set of Quality Criteria for Health Related Websites. The specific aim was to draw up a commonly agreed set of simple quality criteria on which Member States, as well as public and private bodies, may draw in the development of quality initiatives for health related websites. These criteria should be applied in addition to relevant Community law. Methods A meeting was held during 2001 which drew together key players from Government departments, International Organisations, non-governmental organisations and industry, to explore current practices and experiments in this field. Some sixty invited participants from all the Member States, Norway, Switzerland, and the United States of America took part in the meeting of June 7-8, 2001: they included delegates from industrial, medical, and patient interest groups, delegates from Member States' governments, and key invited speakers from the field of health information ethics. These individuals, and many others, also took part in the web-based consultation which was open from august to November 2001. Results The broad headings for quality criteria identified include Transparency and Honesty, Authority, Privacy and data protection, Updating of information, Accountability, Responsible partnering, Editorial policy, Accessibility, the latter includes attention to guidelines on physical accessibility as well as general findability, searchability, readability, usability, etc. A metadata labelling system may be used to make health data more findable. Such a system may also be used in conjunction with quality criteria to give higher ranking by search engines to those sites or pages labelled as complying with defined quality criteria. Conclusions The set of quality criteria is based upon a broad consensus among specialists in this field, health authorities, and prospective users. It is now to be expected that national and regional health authorities, relevant professional associations, and private medical website owners will 1) implement the Quality Criteria for Health Related Websites in a manner appropriate to their website and consumers; 2) develop information campaigns to educate site developers and citizens about minimum quality standards for health related websites; 3) draw on the wide range of health information offered across the European Union and localise such information for the benefit of citizens (translation and cultural adaptation); 4) exchange information and experience at European level about how quality standards are being implemented.

Weight, inflammation, cancer-related symptoms and health related quality of life among breast cancer survivors.  

PubMed

Maintaining weight is important for better prognosis of breast cancer survivors. The associations between weight and cancer-related symptoms are not known. We examined associations among weight, weight change, inflammation, cancer-related symptoms, and health-related quality of life (HRQOL) in a cohort of stage 0-IIIA breast cancer survivors. Participants were recruited on average 6 months (2–12 months) after diagnosis. Height, weight, and C-reactive protein (CRP) were assessed at approximately 30 months post-diagnosis; cancer-related symptoms (chest wall and arm symptoms, vasomotor symptoms, urinary incontinence, vaginal symptoms, cognition/mood problems, sleep, sexual interest/function), and HRQOL (SF-36) were assessed at approximately 40 months post-diagnosis. Weight was measured at baseline in a subset. Data on 661 participants were evaluable for body mass index (BMI); 483 were evaluable for weight change. We assessed associations between BMI (<25.0, 25.0–29.9, ?30.0 kg/m2), post-diagnosis weight change (lost ?5 %, weight change <5 %, gained ?5 %), and CRP (tertile) with cancer-related symptoms and HRQOL using analysis of covariance. Higher symptoms scores indicate more frequent or severe symptoms. Higher HRQOL scores indicate better HRQOL. Compared with those with BMI <25 kg/m2, women with BMI ?30 kg/m2 had the following scores: increased for arm symptoms (+25.0 %), urinary incontinence (+40.0 %), tendency to nap (+18.9 %), and poorer physical functioning (?15.6 %, all p < 0.05). Obese women had lower scores in trouble falling asleep (?9.9 %; p < 0.05). Compared with weight change <5 %, participants with ?5 % weight gain had lower scores in physical functioning (?7.2 %), role-physical (?15.5 %) and vitality (?11.2 %), and those with weight loss ?5 % had lower chest wall (?33.0 %) and arm symptom scores (?35.5 %, all p < 0.05). Increasing CRP tertile was associated with worse scores for chest wall symptoms, urinary incontinence, physical functioning, role-physical, vitality and physical component summary scores (all P trend < 0.05). Future studies should examine whether interventions to maintain a healthy weight and reduce inflammation could alleviate cancer-related symptoms and improve HRQOL. PMID:23797178

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

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.

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.

PubMed Central

The goal of this study was to describe how activists engaged in campaigns to change alcohol policies in inner city areas framed alcohol problems, and whether or not their frameworks reflected major models used in the field, such as the alcoholism as a disease model, an alcohol problems perspective, or a public health approach to alcohol problems. The findings showed that activists’ models shared some aspects with dominant approaches which tend to focus on individuals and to a lesser extent on regulating alcohol marketing and sales. However, activists’ models differed in significant ways by focusing on community level problems with alcohol; on problems with social norms regarding alcohol use; and on the relationship of alcohol use to illicit drugs.

Severe problem behaviors such as aggression, self-injury, and property destruction can result in injury, and require specialized and expensive treatment. This article reviews outcome research published since 1995 that used behavioral techniques to decrease severe problem behaviors among children and adolescents with autism spectrum disorder and/or intellectual disability. Many relatively simple interventions were reported to significantly reduce severe problem behavior, which offers hope for practitioners. Nonetheless, these studies also reveal a risk for injury and a need for specialized assessment and placement, careful tracking, and high-quality treatment that few agencies could likely replicate without increases in training and support.

[Some problems in assessing the quality of rendering medical assistance to people with multiple sclerosis].  

PubMed

To solve the problem of medical and social assistance to people with multiple sclerosis (MS) is possible in employing a system/ comprehensive approach which involves appropriate material basis and appropriate structures, systems, sub-systems with a definite area of their activities and functional interrelations between them. The quality of medical services is a complicated category that is defined by many characteristics. One needs certain equipment to manage in order to obtain the quality while based on the system approach. Experts in the area of quality management inform that, currently, the Russian healthcare is mostly characterized by primary level of quality, which is represented by unsystematic management of the quality and unsystematic (unstable) quality. The methodology of improving the quality is a multistage one. In accordance with the management cycle of Deming-Schuchart or the cycle of PDCA ('P' is for 'plan', 'D' is for 'deed', 'C' is for 'control' and checking the conformity of the result planned to that in the end, and, 'A' is for 'adjustment' of actions depending on the results achieved), the methodology comprises certain problems, an analysis of the system, an action plan development, testing proposed changes in pilot institutions, and practical application in the healthcare system. The article attempts to analyze basic problems and difficulties in setting up medical assistance for a resource-consuming group of patients, by the example of 382 patients with MS, taking into account the experience acquired in a test of application of management systems for medical assistance quality, which is based on international standards (ISO 9000), in order to find possible ways to overcome the existing negative processes and facts.

Vision Related Quality of Life in Patients with Keratoconus  

PubMed Central

Purpose. The purpose of this study is to evaluate the vision related quality of life in patients with keratoconus by using the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25). Methods. Thirty patients presented with keratoconus (keratoconus group) and 30 healthy patients (control group) were included in this study. Twenty patients were using rigid gas permeable and 10 patients were not using contact lenses in keratoconus group. High and low contrast visual acuity and mean K values of the patients were recorded. Each subject completed the 25-item NEI-VFQ-25. Results. All subscales of NEI-VFQ-25 were lower in the keratoconus patients. The difference was more evident in the subscales of general vision, ocular pain, near vision, vision-specific mental health, vision-specific role difficulties, and peripheral vision (P < 0.05). Overall composite score was 75.2?±?17.2 in the keratoconus group and 93.2?±?5.6 in the control group (P = 0.00). Contact lens wearers had higher best corrected visual acuity in comparison with noncontact lens wearers (P = 0.028). Patients with low visual acuity (logMAR?>?0.4) in the better eye had lower distance vision, social functioning, mental health, and role difficulties. Meanwhile, patients with low visual acuity (logMAR?>?0.4) in the worse eye had lower general health scores (P < 0.05). Conclusions. Vision related quality of life was worse in keratoconus patients. Success in the contact lens usage and maintaining higher visual acuity may improve vision related quality of life. PMID:24868455

Income Inequality, Alcohol Use, and Alcohol-Related Problems  

PubMed Central

Objectives We examined the relationship between state-level income inequality and alcohol outcomes and sought to determine whether associations of inequality with alcohol consumption and problems would be more evident with between-race inequality measures than with the Gini coefficient. We also sought to determine whether inequality would be most detrimental for disadvantaged individuals. Methods Data from 2 nationally representative samples of adults (n = 13 997) from the 2000 and 2005 National Alcohol Surveys were merged with state-level inequality and neighborhood disadvantage indicators from the 2000 US Census. We measured income inequality using the Gini coefficient and between-race poverty ratios (Black–White and Hispanic–White). Multilevel models accounted for clustering of respondents within states. Results Inequality measured by poverty ratios was positively associated with light and heavy drinking. Associations between poverty ratios and alcohol problems were strongest for Blacks and Hispanics compared with Whites. Household poverty did not moderate associations with income inequality. Conclusions Poverty ratios were associated with alcohol use and problems, whereas overall income inequality was not. Higher levels of alcohol problems in high-inequality states may be partly due to social context. PMID:23237183

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

Mental Health, Sleep Quality, Drinking Motives, and Alcohol-Related Consequences: A Path-Analytic Model  

PubMed Central

Objective: Poor mental health, sleep problems, drinking motivations, and high-risk drinking are prevalent among college students. However, research designed to explicate the interrelationships among these health risk behaviors is lacking. This study was designed to assess the direct and indirect influences of poor mental health (a latent factor consisting of depression, anxiety, and stress) to alcohol use and alcohol-related consequences through the mediators of global sleep quality and drinking motives in a comprehensive model. Method: Participants were 1,044 heavy-drinking college students (66.3% female) who completed online surveys. Results: A hybrid structural equation model tested hypotheses involving relations leading from poor mental health to drinking motives and poorer global sleep quality to drinking outcomes. Results showed that poor mental health significantly predicted all four subscales of drinking motivations (social, coping, conformity, and enhancement) as well as poor sleep. Most of the drinking motives and poor sleep were found to explain alcohol use and negative alcohol consequences. Poor sleep predicted alcohol consequences, even after controlling for all other variables in the model. The hypothesized mediational pathways were examined with tests of indirect effects. Conclusions: This is the first study to assess concomitantly the relationships among three vital health-related domains (mental health, sleep behavior, and alcohol risk) in college students. Findings offer important implications for college personnel and interventionists interested in reducing alcohol risk by focusing on alleviating mental health problems and poor sleep quality.

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 Problem of Colliding Networks and its Relation to Cancer  

E-print Network

Complex systems, ranging from living cells to human societies, can be represented as attractor networks, whose basic property is to exist in one of allowed states, or attractors. We noted that merging two systems that are in distinct attractors creates uncertainty, as the hybrid system cannot assume two attractors at once. As a prototype of this problem, we explore cell fusion, whose ability to combine distinct cells into hybrids was proposed to cause cancer. By simulating cell types as attractors, we find that hybrids are prone to assume spurious attractors, which are emergent and sporadic states of networks, and propose that cell fusion can make a cell cancerous by placing it into normally inaccessible spurious states. We define basic features of hybrid networks and suggest that the problem of colliding networks has general significance in processes represented by attractor networks, including biological, social, and political phenomena.

Progress on PRONGHORN Application to NGNP Related Problems  

SciTech Connect

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.

Aims To assess the vision-related quality of life of corneal transplant recipients using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25), and to identify the socio-demographic factors that associate with patients' self-assessment of perceived visual function. Methods Thirty patients who received corneal transplants were included in this prospective observational, cross-sectional study. Socio-demographic and clinical data, including age, sex, systemic health status, employment status, visual acuity, reason of corneal transplantation, laterality of corneal graft, and follow-up period were collected. NEI VFQ-25 was scored using Rasch analysis. Subgroup analyses were also performed. Results Age, sex, visual acuity, and health status had no significant correlation or association with the Rasch-transformed score. Patients who received bilateral corneal grafts were significantly less able socioemotionally than those with unilateral graft. Patients who became unemployed or retired after transplantation were also significantly less able in both visual functioning and socioemotional status. Conclusion Corneal transplant recipients had a decreased vision-related quality of life as demonstrated by the NEI VFQ-25. Apart from anatomical success and visual acuity, ophthalmologists should also consider other aspects of visual outcome. In particular, those who received bilateral grafts require more attention. Employment programmes should be part of corneal transplantation rehabilitation planning. PMID:22744389

Health-Related Quality of Life and Quality of Sexual Life in Obese Subjects  

PubMed Central

The increased prevalence of obesity represents, currently, one of the major public health issues, due to its consequences on physical and psychological health status as well as on the psychosocial functioning. As defined by the World Health Organization, sexual health is “a state of physical, emotional, mental, and social well-being in relation to sexuality.” The aim of the present study was to explore the relationship between sexual life in obese subjects and quality of life, psychological status, and disability. Methods. 95 obese subjects were recruited from June 2012 to February 2013 and underwent physical examination and measures for the assessment of quality of life, sexual life, psychological status, and disability. Results. In obese subjects sexual life was related to gender, age, psychological status, disability, and quality of life. Conclusion. As obesity is a multifactorial disease, and is accompanied by multiple comorbidities, it is difficult to identify a single causative factor responsible for the impairment of sexual life in obese subjects; thus, a thorough, multidimensional evaluation including sexual function assessment should be performed in obese people.

Inverse Spin Glass and Related Maximum Entropy Problems  

NASA Astrophysics Data System (ADS)

If we have a system of binary variables and we measure the pairwise correlations among these variables, then the least structured or maximum entropy model for their joint distribution is an Ising model with pairwise interactions among the spins. Here we consider inhomogeneous systems in which we constrain, for example, not the full matrix of correlations, but only the distribution from which these correlations are drawn. In this sense, what we have constructed is an inverse spin glass: rather than choosing coupling constants at random from a distribution and calculating correlations, we choose the correlations from a distribution and infer the coupling constants. We argue that such models generate a block structure in the space of couplings, which provides an explicit solution of the inverse problem. This allows us to generate a phase diagram in the space of (measurable) moments of the distribution of correlations. We expect that these ideas will be most useful in building models for systems that are nonequilibrium statistical mechanics problems, such as networks of real neurons.

Learning Problems Related to the Concept of Field  

NASA Astrophysics Data System (ADS)

The concept of field has formed itself through a process of elaboration of concepts both on the historical level, and on that of mathematic formalism (integral or differential approach, Lagrangian and Hamiltonian formalism), and in the relationship between mathematics and physics. In didactic tradition it is used as an example of the formalised analogical process. Its phenomenological aspects and its characteristics of time and space are only partially described for the various types of field, mixing the descriptive and interpretative levels. In this review we select some of the main teaching-learning problems and student's diffculties with learning the concept of field, that many researches have stressed, such as: the concept of field and its representation by lines of force, the difference between field and force, the connection between field and its sources, the concept of the field's superposition and the interpretation of mathematical formulas, the application of the third principle of dynamics, the motion of the field's characteristic particles in the field itself. We consider the field in static situations, because these learning problems are fundamental and basic for when we will pass to dynamic situations (electromagnetic field).

Symplectic structures related with higher order variational problems  

E-print Network

In this paper we derive the symplectic framework for field theories defined by higher-order Lagrangians. The construction is based on the symplectic reduction of suitable spaces of iterated jets. The possibility of reducing a higher-order system of PDEs to a constrained first-order one, the symplectic structures naturally arising in the dynamics of a first-order Lagrangian theory, and the importance of the Poincar\\'e-Cartan form for variational problems, are all well-established facts. However, their adequate combination corresponding to higher-order theories is missing in the literature. Here we obtain a consistent and truly finite-dimensional canonical formalism, as well as a higher-order version of the Poincar\\'e-Cartan form. In our exposition, the rigorous global proofs of the main results are always accompanied by their local coordinate descriptions, indispensable to work out practical examples.

Health-related quality of life outcomes after kidney transplantation  

PubMed Central

With the improvements in short and long term graft and patient survival after renal transplantation over the last two decades Health-Related Quality of Life (HRQL) is becoming an important additional outcome parameter. Global and disease specific instruments are available to evaluate objective and subjective QOL. Among the most popular global tools is the SF-36, examples of disease specific instruments are the Kidney Transplant Questionnaire (KTQ), the Kidney Disease Questionnaire (KDQ) and the Kidney Disease-Quality of Life (KDQOL). It is generally accepted that HRQL improves dramatically after successful renal transplantation compared to patients maintained on dialysis treatment but listed for a transplant. It is less clear however which immunosuppressive regimen confers the best QOL. Only few studies compared the different regimens in terms of QOL outcomes. Although limited in number, these studies seem to favour non-cyclosporine based protocols. The main differences that could be observed between patients on cyclosporine versus tacrolimus or sirolimus therapy concern the domains of appearance and fatigue. This may be explained by two common adverse effects occurring under cyclosporine therapy, gingival hyperplasia and hair growth. Another more frequently occurring side effect under calcineurin inhibitor therapy is tremor, which may favour CNI free protocols. This hypothesis, however, has not been formally evaluated in a randomised trial using HRQL measurements. In summary HRQL is becoming more of an issue after renal transplantation. Whether a specific immunosuppressive protocol is superior to others in terms of HRQL remains to be determined. PMID:14713316

Relation of Biospeckle Activity with Quality Attributes of Apples  

PubMed Central

Biospeckle is nondestructive optical technique based on the analysis of variations of laser light scattered from biological samples. Biospeckle activity reflects the state of the investigated object. In this study the relation of biospeckle activity (BA) with firmness, soluble solids content (SSC), titratable acidity (TA) and starch content (SC) during the shelf life of seven apple cultivars was studied. The results showed that the quality attributes change significantly during storage. Significant and pronounced positive correlation between BA and SC was found. This result shows that degradation of starch granules, which could be stimulated to vibration by intracellular cyclosis, causes a lesser number of laser light scattering centers and results in smaller apparent biospeckle activity.

Semen quality in relation to biomarkers of pesticide exposure.  

PubMed Central

We previously reported reduced sperm concentration and motility in fertile men in a U.S. agrarian area (Columbia, MO) relative to men from U.S. urban centers (Minneapolis, MN; Los Angeles, CA; New York, NY). In the present study we address the hypothesis that pesticides currently used in agriculture in the Midwest contributed to these differences in semen quality. We selected men in whom all semen parameters (concentration, percentage sperm with normal morphology, and percentage motile sperm) were low (cases) and men in whom all semen parameters were within normal limits (controls) within Missouri and Minnesota (sample sizes of 50 and 36, respectively) and measured metabolites of eight current-use pesticides in urine samples provided at the time of semen collection. All pesticide analyses were conducted blind with respect to center and case-control status. Pesticide metabolite levels were elevated in Missouri cases, compared with controls, for the herbicides alachlor and atrazine and for the insecticide diazinon [2-isopropoxy-4-methyl-pyrimidinol (IMPY)]; for Wilcoxon rank test, p = 0.0007, 0.012, and 0.0004 for alachlor, atrazine, and IMPY, respectively. Men from Missouri with high levels of alachlor or IMPY were significantly more likely to be cases than were men with low levels [odds ratios (ORs) = 30.0 and 16.7 for alachlor and IMPY, respectively], as were men with atrazine levels higher than the limit of detection (OR = 11.3). The herbicides 2,4-D (2,4-dichlorophenoxyacetic acid) and metolachlor were also associated with poor semen quality in some analyses, whereas acetochlor levels were lower in cases than in controls (p = 0.04). No significant associations were seen for any pesticides within Minnesota, where levels of agricultural pesticides were low, or for the insect repellent DEET (N,N-diethyl-m-toluamide) or the malathion metabolite malathion dicarboxylic acid. These associations between current-use pesticides and reduced semen quality suggest that agricultural chemicals may have contributed to the reduction in semen quality in fertile men from mid-Missouri we reported previously.

[Problems related to African customs and ritual mutilations].  

PubMed

Few peoples of the world have completely avoided the practice of ritual mutilation, which at present appears particularly widespread in Africa. This article discusses several forms of mutilation practiced in Africa, most of which are currently rare and disappearing. Cranial deformation due to mechanical pressure in the early years of life was common in Africa and elsewhere, but its origins are difficult to trace. Collars were worn by females in some parts of Africa to elongate the neck, sometimes so weakening the skeletal structure that the head could not be held upright without the device. Many women subjected to their use died at young ages of cerebral vascular accidents. The shortening of the uvula is regarded as a benign mutilation, but could result in infection and death due to the unsanitary conditions in which it was practiced. Perforations of the nose, lips, or ears to permit use of personal adornments were common. Filing of teeth and scarring were other techniques of uncertain origin. Among genital mutilations, circumcision was the most widely known and commonly practiced. It was usually performed on boys of 7-12 years and was invested with ritual significance. Amputation of the gland by unskilled operators or later development of pseudoelephantiasis, nodules, penile fistulas, or stenosis were not rare complications. The custom of excising the clitoris and the labia minora was imported from the Near East and spread west and south with the penetration of Islam. It is still carried out at puberty. Although life-threatening complications are rare, local sequelae including urinary problems, vaginal obstruction, and scleroses leading to vesicovaginal fistulas during childbirth are common. The motive appears to be to prove the subordination of women and the prohibition of all sexual pleasure. Infibulation involves excision of the external genitalia and the creation of an orifice the size of a pencil to allow escape of menstrual fluid and urine. The operation is performed on little girls of 7 or 8. The husband creates a small opening at the time of marriage, and the woman is cut open and sewn up at each delivery. The complications are variable and may include local infection, hemorrhage, anemia, clitoral cysts, cystitis and acute urinary retention, vesical lithiasis, and psychic problems. Disinfibulation is complicated by sectioning of the anal sphincter, bladder damage, and uterine prolapse. The custom is only seen among Islamic peoples. PMID:12312726

Love and the commitment problem in romantic relations and friendship  

Microsoft Academic Search

On the basis of the proposition that love promotes commitment, the authors predicted that love would motivate approach, have a distinct signal, and correlate with commitment-enhancing pro- cesses when relationships are threatened. The authors studied romantic partners and adolescent opposite-sex friends during interactions that elicited love and threatened the bond. As expected, the experience of love correlated with approach-related states

Theory of Quantum Pulse Position Modulation and Related Numerical Problems  

E-print Network

The paper deals with quantum pulse position modulation (PPM), both in the absence (pure states) and in the presence (mixed states) of thermal noise, using the Glauber representation of coherent laser radiation. The objective is to find optimal (or suboptimal) measurement operators and to evaluate the corresponding error probability. For PPM, the correct formulation of quantum states is given by the tensorial product of m identical Hilbert spaces, where m is the PPM order. The presence of mixed states, due to thermal noise, generates an optimization problem involving matrices of huge dimensions, which already for 4-PPM, are of the order of ten thousand. To overcome this computational complexity, the currently available methods of quantum detection, which are based on explicit results, convex linear programming and square root measurement, are compared to find the computationally less expensive one. In this paper a fundamental role is played by the geometrically uniform symmetry of the quantum PPM format. The evaluation of error probability confirms the vast superiority of the quantum detection over its classical counterpart.

Postadmission sepsis as a screen for quality problems: a case-control study.  

PubMed

The present on admission (POA) indicator used with diagnosis codes listed in hospital discharge abstracts makes it possible to screen for possible in-hospital complications, which may in turn point to quality of care problems. A case-control study was performed among 382 patients from 30 New York State hospitals to see if lapses in quality were associated with the development of postadmission sepsis. Cases with hospital-acquired sepsis (labeled not POA) were compared with matched controls without sepsis. The authors found that central venous catheters and emergently inserted peripheral intravenous catheters were associated with subsequent development of sepsis. Urethral catheters were associated with sepsis for medical patients but not for surgical patients. Adherence to several process of care guidelines was incomplete but none occurred statistically significantly more frequently among sepsis cases than controls. Using discharge abstract diagnosis codes to determine the presence of postadmission complications shows promise for identifying areas for quality improvement. PMID:24226649

Longitudinal relations between parental drinking problems, family functioning, and child adjustment.  

PubMed

Relations between maternal and paternal problem drinking symptoms and destructive marital conflict, parenting problems, and children's internalizing and externalizing problems were investigated. Participants were community families with a child in kindergarten who completed questionnaire measures at baseline (N=235), 1 year later (N=227), and 2 years later (N=215). Structural equation modeling revealed that paternal problem drinking at Time 1 was associated with greater destructive marital conflict 1 year later. In turn, destructive marital conflict was related to decreased parental warmth and increased parental psychological control; these parenting problems were associated with greater child internalizing and externalizing problems at the third time point. Further analyses revealed that the indirect effects of paternal drinking on children's adjustment were significant, and that relations remained even after including autoregressive effects. Findings are discussed in terms of family process models for relations between parental drinking and child adjustment problems. PMID:18211734

Testicular cancer: the psychosocial problems of patients and their relatives.  

PubMed

The idea that cancer may be associated with emotional states or personality structure is not a new one. However, psychosocial research has fallen in and out of favour with the medical profession, but is currently experiencing a massive upsurge of popularity as a focus for investigation. In this paper I examine longstanding individualistic assumptions and the contradictory and sometimes similar findings of research in this field despite the differing and ever increasing sophistication of measurement techniques and study design. I have also attempted to formulate a theory that may explain why individualistic traits continue to take precedence over social factors and why psychosocial research has been elevated into a position of medical importance in recent years. At the Royal Marsden Hospital, Sutton, we studied 102 men with testicular cancer and 77 of their relatives in an attempt to establish the extent of psychosocial morbidity in these two groups. Despite an excellent prognosis we found high levels of psychological morbidity in both the patients and their relatives, even five years after their diagnosis. 'Extrinsic' social variables such as unemployment experience of patients and childlessness among partners may explain psychiatric symptoms. 'Extrinsic' social variables, however, should be examined in conjunction with individualistic 'intrinsic' factors emotional states may be but symptoms of the social context of the subject.

Oral health, nutrition, and oral health-related quality of life among Korean older adults.  

PubMed

Oral health affects older adults and their quality of life. Oral care is reported to have a low priority in nursing care of older adults, and repeated assessments to detect oral health problems are seldom performed. The purpose of this study was to investigate the relationships among level of oral health, nutrition, and oral health-related quality of life (OHRQL) and to identify predictors of OHRQL in Korean older adults. The design was a descriptive, correlational study. The level of oral pain contributed most significantly to OHRQL, followed by nutrition and number of teeth. These three predictor variables explained 46.4% of the variance in OHRQL. Older adults could benefit from oral health care, such as routine screening for oral health and nutritional status. Nurses are at the forefront in providing such services, and it is recommended they integrate oral health care into their routine nursing care plans. PMID:18942537

Eco-innovative design approach: Integrating quality and environmental aspects in prioritizing and solving engineering problems  

NASA Astrophysics Data System (ADS)

This study proposes an eco-innovative design process taking into consideration quality and environmental aspects in prioritizing and solving technical engineering problems. This approach provides a synergy between the Life Cycle Assessment (LCA), the nonquality matrix, the Theory of Inventive Problem Solving (TRIZ), morphological analysis and the Analytical Hierarchy Process (AHP). In the sequence of these tools, LCA assesses the environmental impacts generated by the system. Then, for a better consideration of environmental aspects, a new tool is developed, the non-quality matrix, which defines the problem to be solved first from an environmental point of view. The TRIZ method allows the generation of new concepts and contradiction resolution. Then, the morphological analysis offers the possibility of extending the search space of solutions in a design problem in a systematic way. Finally, the AHP identifies the promising solution(s) by providing a clear logic for the choice made. Their usefulness has been demonstrated through their application to a case study involving a centrifugal spreader with spinning discs.

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.

Health-related quality of life and related factors of military police officers  

PubMed Central

Purpose The present study aimed to determine the effect of demographic characteristics, occupation, anthropometric indices, and leisure-time physical activity levels on coronary risk and health-related quality of life among military police officers from the State of Santa Catarina, Brazil. Methods The sample included 165 military police officers who fulfilled the study’s inclusion criteria. The International Physical Activity Questionnaire and the Short Form Health Survey were used, in addition to a spreadsheet of socio-demographic, occupational and anthropometric data. Statistical analyses were performed using descriptive analysis followed by Spearman Correlation and multiple linear regression analysis using the backward method. Results The waist-to-height ratio was identified as a risk factor low health-related quality of life. In addition, the conicity index, fat percentage, years of service in the military police, minutes of work per day and leisure-time physical activity levels were identified as risk factors for coronary disease among police officers. Conclusions These findings suggest that the Military Police Department should adopt an institutional policy that allows police officers to practice regular physical activity in order to maintain and improve their physical fitness, health, job performance, and quality of life.

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.

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

CORRELATES OF HEALTH-RELATED QUALITY OF LIFE IN AFRICAN AMERICAN AND CAUCASIAN STROKE CAREGIVERS  

PubMed Central

Objective Stroke is a leading cause of long-term disability in the United States. Family caregivers are susceptible to negative outcomes as a result of their caregiving role. A stress process model was utilized to identify characteristics of stroke caregivers who are at risk for poor physical and mental health-related quality of life (QOL). Research Method Individuals who experienced an incident stroke event within the previous year were identified from a larger epidemiologic study of stroke incidence. These stroke survivors were enrolled in the Caring for Adults Recovering from the Effects of Stroke (CARES) study along with their primary family caregivers (N=146 dyads). Caregivers completed a baseline telephone interview that assessed physical and mental health-related QOL, problems their family members were experiencing, appraisals of those problems, and caregiver resources. Results Objective stressors, appraisals, and caregiver resources were related to caregiver physical and mental health-related QOL, p’s <.05. Objective stressors were found to have a stronger association with caregiver mental health than physical health. Hierarchical regression models showed the relative importance of each category of predictors. In the final models, older age and receiving more support were associated with worse physical health-related QOL while African American race and fewer stroke survivor problems were associated with better mental health. Implications The correlates of health-related QOL identified in this national sample of caregivers can help identify stroke caregivers who are at-risk for poor adjustment to the caregiving role and aid in identifying areas that can potentially be intervened upon for these caregivers.

Lifestyle and health-related quality of life in Asian patients with total hip arthroplasties.  

PubMed

Total hip arthroplasty reduces pain and restores physical function in patients with hip joint problems. This study examined lifestyle and health-related quality of life before and after total hip arthroplasty in Japanese and Chinese patients. Two hospitals in China recruited 120 patients and 120 Japanese patients matched by age and operative status were drawn from a prospective cohort database. Oxford Hip Score, EuroQol, and characteristics of Asian lifestyle and attitudes toward the operation were assessed. There were no differences between patients from the two countries in quality-of-life-scale scores: postoperative patients had significantly better quality-of-life scores than preoperative patients in both countries. In China, patients who reported that living at home was inconvenient had significantly worse Oxford Hip Scores than those who did not. Mean scores for anxiety items concerning possible dislocation and durability of the implant were significantly higher in Japanese than in Chinese subjects. Our findings suggest that providing information about housing conditions and lifestyles would result in improved quality of life and reduced anxiety in patients with implanted joints. PMID:24845456

Mental Health Problems among Adolescents with Early-Onset and Long-Duration Type 1 Diabetes and Their Association with Quality of Life: A Population-Based Survey  

PubMed Central

Objective To evaluate mental health problems and associations between mental health problems and health-related quality of life in adolescents with type 1 diabetes in comparison with the general population. Method A total of 629 11- to 17-year-olds with early-onset and long-lasting type 1 diabetes and their parents completed comprehensive questionnaires. Mental health was assessed using the parent- and self-report versions of the Strengths and Difficulties Questionnaire (SDQ). The Revised Children's Quality of Life Questionnaire (KINDL-R) was used to measure quality of life. The comparison group (n?=?6,813) was a representative sample from the German KiGGS study. Results The proportion of youths with mental health problems (defined as abnormal SDQ total difficulties score) was, based on self-reports, 4.4% in the patient group and 2.9% in the general population (adjusted OR?=?1.61, p?=?0.044); and based on proxy reports, 7.9% in the patient group and 7.2% in the general population (OR?=?1.05, p?=?0.788). Youths with type 1 diabetes and self-reported mental health problems scored worse in the KINDL-R subscales of physical well-being (adjusted average difference ??=??16.74, p<0.001) and family (??=??11.09, p?=?0.017), and in the KINDL-R total score (??=??8.09, p<0.001), than peers with self-reported mental health problems. The quality of life of diabetic adolescents and proxy-reported mental health problems did not differ from peers with proxy-reported mental health problems adjusted for confounders. Conclusions Compared with the general population with mental health problems, the quality of life of adolescents with type 1 diabetes who report mental health problems is more severely impaired. This observation calls for early prevention and intervention as part of pediatric diabetes long-term care. PMID:24637957

Quality of Working Life of Nurses and its Related Factors  

PubMed Central

Background: Nurses as the largest group of health care providers should enjoy a satisfactory quality of working life to be able to provide quality care to their patients. Therefore, attention should be paid to the nurses’ working life. Objectives: This study aimed to investigate the quality of nurses' working life in Kashans' hospitals during 2012. Materials and Methods: This cross-sectional study was conducted on 200 nurses during 2012. The data-gathering instrument consisted of two parts. The first part consisted of questions on demographic information and the second part was the Walton’s quality of work life questionnaire. Data were analyzed using the SPSS software. For statistical analysis T test and one way ANOVA were used. Results: The results of the study showed that 60% of nurses reported that they had moderate level of quality of working life while 37.1% and 2% had undesirable and good quality of working life, respectively. Nurses with associate degrees reported a better quality of working life than others. A significant relationship was found between variables such as education level, work experience, and type of hospital with quality of working life score (P < 0.05). No significant differences were observed between quality of working life score of nurses with employment status (P = 0.061), salary (P = 0.052), age, gender and marital status (P > 0.05). Conclusions: Nurses' quality of work life was at the moderate level. As quality of work life has an important impact on attracting and retaining employees, it is necessary to pay more attention to the nurses’ quality of work life and its affecting factors.

University and Industry Collaboration to Solve Welding Quality Problem Using Design of Experiments (DOE)  

NSDL National Science Digital Library

A local automotive seat supplier experienced a major quality problem in the fabrication of the metal seat frame used in the manufacture of the front bucket seats of automobiles. This quality concern was failure of the seat cushion weld nuts to adhere to the metal seat frame during random quality torque testing at the lower specification limit. A company executive contacted Middle Tennessee State University (MTSU) and requested a six-sigma study to determine the root causes of the problem and to work with his engineering and operations personnel to implement countermeasures. The six-sigma project team was setup by the company Project Champion and was led by the university Project Leader. The team consisted of the company welding engineer, three operations personnel, the MTSU professor, a graduate student, and three undergraduates. This paper focuses on the Design-of-Experiments portion of this project that required close collaboration between the industry and the university personnel.

Adjustment problems and maladaptive relational style: a mediational model of sexual coercion in intimate relationships.  

PubMed

Four hundred and fifty-three married or cohabitating couples participated in the current study. A meditational model of men's perpetration of sexual coercion within an intimate relationship was examined based on past theories and known correlates of rape and sexual coercion. The latent constructs of adjustment problems and maladaptive relational style were examined. Adjustment problem variables included perceived stress, perceived low social support, and marital discord. Maladaptive relational style variables included psychological aggression, dominance, and jealousy. Sexual coercion was a combined measure of men's reported perpetration and women's reported victimization. As hypothesized, adjustment problems significantly predicted sexual coercion. Within the meditational model, adjustment problems were significantly correlated with maladaptive relational style, and maladaptive relational style significantly predicted sexual coercion. Once maladaptive relational style was introduced as a mediator, adjustment problems no longer significantly predicted sexual coercion. Implications for treatment, limitations, and future research are discussed. PMID:23329647

Learning to relate qualitative and quantitative problem representations in a model-based setting for collaborative problem solving  

NSDL National Science Digital Library

In an experimental study, we investigated how 10th graders acquire, extend, and successively relate knowledge about qualitative and quantitative aspects of classical mechanics. The study was made up of 2 main phases. In the 1st phase, students were taught either qualitative or quantitative aspects of classical mechanics by means of 2 different instructional units. In both units, concept maps were used for the presentation of information. In the 2nd phase, dyads were formed with students who worked on different instructional units and thus possessed systematically different knowledge. The 2 students collaboratively worked on problems that were beyond the competence of each of them and demanded the coordinated useof knowledge about qualitative and quantitative aspects. Before and after the instruction as well as after the collaborative problem solving, students had to work on multicomponent tests. In addition, during the collaborative problem solving, protocols were taken of the students' mutual exchange of information An analysis of the multicomponent tests revealed that qualitative as well as quantitative knowledge can successfully be taught by means of concept maps. Students who initially were taught qualitative aspects of physics gained significantly more from the information provided by their quantitatively instructed partners during the collaborative problem solving than the other way around. An analysis of individual problem-solving attempts uncovered that students learned to construct increasingly more complete qualitative and quantitative problem representations. An explorative protocol analysis of the students' dialogues further indicated that the students gradually shifted their focus from quantitative to qualitative problem representations during collaborative problem solving.

Geriatric oncology: comparing health related quality of life in head and neck cancer patients  

PubMed Central

Background Population ageing is increasing the number of people annually diagnosed with cancer worldwide, once most types of tumours are age-dependent. High-quality healthcare in geriatric oncology requires a multimodal approach and should take into account stratified patient outcomes based on factors other than chronological age in order to develop interventions able to optimize oncology care. This study aims to evaluate the Health Related Quality of Life in head and neck cancer patients and compare the scores in geriatric and younger patients. Methods Two hundred and eighty nine head and neck cancer patients from the Oncology Portuguese Institute participated in the Health Related Quality of Life assessment. Two patient groups were considered: the geriatric (? 65 years old, n = 115) and the younger (45-60 years old, n= 174). The EORTC QLQ-C30 and EORTC QLQ-H&N35 questionnaires were used. Results Head and neck cancer patients were mostly males, 77.4% within geriatric group and 91.4% among younger patients group. The most frequent tumour locations were similar in both groups: larynx, oral cavity and oropharynx - base of the tongue. At the time of diagnosis, most of younger male patients were at disease stage III/IV (55.9%) whereas the majority of younger female patients were at disease stage I/II (83.4%). The geriatric patient distribution was found to be similar in any of the four disease stages and no gender differences were observed. We found that age (geriatrics scored generally worse), gender (females scored generally worse), and tumour site (larynx tumours denounce more significant problems between age groups) clearly influences Health Related Quality of Life perceptions. Conclusions Geriatric oncology assessments signalize age-independent indicators that might guide oncologic geriatric care optimization. Decision-making in geriatric oncology must be based on tumour characteristics and chronological age but also on performance status evaluation, co-morbidity, and patient reported outcomes assessment.

Problem of data quality and the limitations of the infrastructure approach  

NASA Astrophysics Data System (ADS)

The 'Infrastructure Approach' is a PACS implementation methodology wherein the archive, network and information systems interfaces are acquired first, and workstations are installed later. The approach allows building a history of archived image data, so that most prior examinations are available in digital form when workstations are deployed. A limitation of the Infrastructure Approach is that the deferred use of digital image data defeats many data quality management functions that are provided automatically by human mechanisms when data is immediately used for the completion of clinical tasks. If the digital data is used solely for archiving while reports are interpreted from film, the radiologist serves only as a check against lost films, and another person must be designated as responsible for the quality of the digital data. Data from the Radiology Information System and the PACS were analyzed to assess the nature and frequency of system and data quality errors. The error level was found to be acceptable if supported by auditing and error resolution procedures requiring additional staff time, and in any case was better than the loss rate of a hardcopy film archive. It is concluded that the problem of data quality compromises but does not negate the value of the Infrastructure Approach. The Infrastructure Approach should best be employed only to a limited extent, and that any phased PACS implementation should have a substantial complement of workstations dedicated to softcopy interpretation for at least some applications, and with full deployment following not long thereafter.

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. PMID:23949099

Measuring health-related quality of life in men with osteoporosis or osteoporotic fracture  

PubMed Central

Background Osteoporosis is a serious health problem that worsens the quality of life and the survival rate of individuals with this disease on account the osteoporotic fractures. Studies have long focused on women, and its presence in men has been underestimated. While many studies conducted in different countries mainly assess health-related quality of life and identify fracture risks factors in women, few data are available on a Spanish male population. Methods/Design Observational study. Study population Men ? 40 years of age with/without diagnosed osteoporosis and with/without osteoporotic fracture included by their family doctor. Measurements The relationship between customary clinical risk factors for osteoporotic fracture and health-related quality of life in a Spanish male population. A telephone questionnaire on health-related quality of life is made. Statistical analysis The association between qualitative variables will be assessed by the Chi-square test. The distribution of quantitative variables by Student's t-test. If the conditions for using this test are not met, the non-parametric Mann-Whitney's U test will be used. The validation of the results obtained by the FRAX™ tool will be performed by way of the Hosmer-Lemeshow test and by calculating the area under the Receiver Operating Characteristic (ROC) curve (AUC). All tests will be performed with a confidence intervals set at 95%. Discussion The applicability and usefulness of Health-related quality of life (HRQOL) studies are well documented in many countries. These studies allow implementing cost-effective measures in cases of a given disease and reducing the costly consequences derived therefrom. This study attempts to provide objective data on how quality of life is affected by the clinical aspects involved in osteoporosis in a Spanish male population and can be useful as well in cost utility analyses conducted by health authorities. The sample selected is not based on a high fracture risk group. Rather, it is composed of men in the general population, and accordingly comparisons should not lead to erroneous interpretations. A possible bias correction will be ensured by checking reported fractures against healthcare reports and X-rays, or by consulting health care centers as applicable. PMID:21981790

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.

The relations among cumulative risk, parenting, and behavior problems during early childhood  

PubMed Central

Background This study examined relations among cumulative risk, nurturant and involved parenting, and behavior problems across early childhood. Methods Cumulative risk, parenting, and behavior problems were measured in a sample of low-income toddlers participating in a family-centered program to prevent conduct problems. Results Path analysis was utilized to examine longitudinal relations among these constructs, with results supporting an indirect effect of cumulative risk on externalizing and internalizing problems through nurturant and involved parenting. Conclusion Results highlight the importance of cumulative risk during early childhood, and particularly the effect that the level of contextual risk can have on the parenting context during this developmental period.

Assessment of the quality of measures of child oral health-related quality of life  

PubMed Central

Background Several measures of oral health-related quality of life have been developed for children. The most frequently used are the Child Perceptions Questionnaire (CPQ), the Child Oral Impacts on Daily Performances (C-OIDP) and the Child Oral Health Impact Profile (COHIP). The aim of this study was to assess the methodological quality of the development and testing of these three measures. Methods A systematic search strategy was used to identify eligible studies published up to December 2012, using both MEDLINE and Web of Science. Titles and abstracts were read independently by two investigators and full papers retrieved where the inclusion criteria were met. Data were extracted by two teams of two investigators using a piloted protocol. The data were used to describe the development of the measures and their use against existing criteria. The methodological quality and measurement properties of the measures were assessed using standards proposed by the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) group. Results The search strategy yielded 653 papers, of which 417 were duplicates. Following analysis of the abstracts, 119 papers met the inclusion criteria. The majority of papers reported cross-sectional studies (n?=?117) with three of longitudinal design. Fifteen studies which had used the original version of the measures in their original language were included in the COSMIN analysis. The most frequently used measure was the CPQ. Reliability and construct validity appear to be adequate for all three measures. Children were not fully involved in item generation which may compromise their content validity. Internal consistency was measured using classic test theory with no evidence of modern psychometric techniques being used to test unidimensionality of the measures included in the COSMIN analysis. Conclusion The three measures evaluated appear to be able to discriminate between groups. CPQ has been most widely tested and several versions are available. COHIP employed a rigorous development strategy but has been tested in fewer populations. C-OIDP is shorter and has been used successfully in epidemiological studies. Further testing using modern psychometric techniques such as item response theory is recommended. Future developments should also focus on the development of measures which can evaluate longitudinal change. PMID:24758535

Health- related quality of life in diabetic people with different vascular risk  

PubMed Central

Background The number of papers on the health related quality of life of patients with DM has grown in recent years but fewer studies have drawn comparisons between diabetic persons and the general population considering different risk groups. The aim of this study is to examine health related quality of life (HRQOL) in people with diabetes mellitus (DM) and to analyze the differences in HRQOL adjusting by vascular risk. Methods The data used in this analysis was obtained from the responses of 15,926 individuals who participated in the 2006 Catalonia Health Survey. Our analysis provides a number of multivariate statistical models designed for studying HRQOL, based on the EQ-5D questionnaire, controlling for demographic factors of survey participants and variables that identify diagnosed illnesses and health problems. Results Our findings suggest there is a significant, moderate negative relationship between DM and HRQOL in comparison with non diabetic people (absolute value of the coefficient ranges between ?0.04 and ?0.054 points on a scale of 1). A further analysis of subgroups reveals that diabetics who have not had vascular risk factors neither vascular diseases do not have a diminished HRQOL when compared to the non-diabetic population in general, when other factors are controlled for. In contrast, a comparison of diabetics and non-diabetics who exhibit vascular disease or risk factors for vascular disease reveals HRQOL is significantly diminished to a greater extent for those with diabetes (between 0.152 and 0.175 points loss when comparing a non-diabetic person with a diabetic with vascular disease). Also, HRQOL in diabetic patients who have additional risk factors or a vascular disease are lower than people non-diabetic who have additional risk factors or a vascular disease. When we focus our analysis to the EQ-5D dimensions, we observe that diabetic persons who are neither at risk for nor have a diagnosed vascular disease are no more likely than non-diabetics to report problems. However, diabetic patients who have additional risk factors for vascular disease or a diagnosed vascular disease are significantly more likely to report moderated or severe problems in 4 of the 5 dimensions of EQ-5D. Conclusions The HRQOL of a person who has diabetes is not necessarily lower than for a non-diabetic. Control of risk factors associated to vascular diseases is a key factor for an enhanced quality of life. Vascular disease or risk factors for vascular disease, on the other hand, are associated with a significantly diminished quality of life for diabetic persons. PMID:22994940

Health-related quality of life in infertile couples receiving IVF or ICSI treatment  

PubMed Central

Background Infertile couples might experience psychological distress and suffer from impaired health-related quality of life. This study aimed to examine health-related quality of life in infertile couples receiving either in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment. Methods This was a cross-sectional study of quality of life in infertile couples attending to Vali-e-Asr Reproductive Health Research Center or Royan Institute for either IVF or ICSI treatment in Tehran, Iran. Health-related quality of life was assessed using the Short Form Health Survey (SF-36). Patients' demographic and clinical characteristics were also recorded. Data were analyzed to compare quality of life in infertile women and men and to indicate what variables predict quality of life in infertile couples. Results In all 514 women and 514 men (n = 1028) were studied. There were significant differences between women and men indicating that male patients had a better health-related quality of life. Also health-related quality of life was found to be better in infertility due to male factor. Performing logistic regression analysis it was found that female gender, and lower educational level were significant predictors of poorer physical health-related quality of life. For mental health-related quality of life in addition to female gender and lower educational level, younger age also was found to be a significant predictor of poorer condition. No significant results were observed for infertility duration or causes of infertility either for physical or mental health-related quality of life. Conclusion The findings suggest that infertility duration or causes of infertility do not have significant effects on health-related quality of life in infertile couples. However, infertile couples, especially less educated younger women, are at risk of a sub-optimal health-related quality of life and they should be provided help and support in order to improve their health-related quality of life.

Sleep-related and non-sleep-related migraine: interictal sleep quality, arousals and pain thresholds  

PubMed Central

Background The mechanisms associating sleep and migraine are unknown. No previous polysomnographic (PSG) or pain-threshold (PT) study has compared patients with sleep-related migraine attacks (SM), non-sleep related migraine attacks (NSM) and healthy controls. Methods We have performed a blinded, prospective exploratory study with case–control design. Thirty-four healthy controls, 15 patients with SM and 18 patients with NSM had interictal PSG heat-, cold- and pressure PT (HPT, CPT, PPT) recordings and completed diary- and questionnaire on sleep and headache related aspects. Results NSM patients had more slow-wave sleep (SWS) and more K-bursts than SM patients (K-bursts: p?=?0.023 and SWS: p?=?0.030) and controls (K-bursts: p?=?0.009 and SWS: 0.041). NSM patients also had lower HPT and CPT than controls (p?=?0.026 and p?=?0.021). In addition, SM patients had more awakenings and less D-bursts than controls (p?=?0.025 and p?=?0.041). Conclusion SM- and NSM patients differed in objective-, but not subjective sleep quality. NSM patients had PSG findings indicating foregoing sleep deprivation. As foregoing sleep times were normal, a relative sleep deficit might explain reduced PT among NSM patients. The SM patients had signs of slightly disturbed sleep. PMID:23919583

Does Understanding Relational Terminology Mediate Effects of Intervention on Compare Word Problems?  

PubMed Central

The purpose of this study was to assess whether understanding relational terminology (i.e., more, less, and fewer) mediates the effects of intervention on compare word problems. Second-grade classrooms (n = 31) were randomly assigned to 3 conditions: researcher-designed word-problem intervention, researcher-designed calculation intervention, or business-as-usual (teacher-designed) control. Students in word-problem intervention classrooms received instruction on the compare problem type, which included a focus on understanding relational terminology within compare word problems. Analyses, which accounted for variance associated with classroom clustering, indicated that (a) compared to the calculation intervention and business-as-usual conditions, word-problem intervention significantly increased performance on all three subtypes of compare problems and on understanding relational terminology; and (b) the intervention effect was fully mediated by students’ understanding of relational terminology for 1 subtype of compare problems and partially mediated by students’ understanding of relational terminology for the other 2 subtypes.

Depression and Health Related Quality of Life in Adolescent Survivors of a Traumatic Brain Injury: A Pilot Study  

PubMed Central

Traumatic brain injury is (TBI) a leading cause of morbidity and mortality in youth. Adult survivors of a severe pediatric TBI are vulnerable to global impairments, including greater employment difficulties, poor quality of life (HRQoL) and increased risk of mental health problems. When estimating the health related quality of life in adolescents, the presence of anxiety and depression and the quality of social relationships are important considerations, because adolescents are entrenched in social development during this phase of maturation. The influence of anxiety, depression and loneliness on health related quality of life in adolescent survivors of TBI has not been documented. This pilot study aimed to identify and measure the relationship between anxiety, depression and loneliness and perceived health related quality of life in adolescent survivors of a TBI. Method: mixed method/cohort pilot study (11 adolescents, mild to severe TBI; 9 parents), using self-report and proxy-report measures of anxiety, depression, health related quality of life, loneliness and clinical psychiatric interviews (adolescent only). Results: Self-reported depression was significantly correlated with self-reported HRQoL (rs [11]?=??0.88, p<0.001). Age at injury was significantly correlated with self-reported HRQoL (rs [11]?=??0.68, p?=?0.02). Self-reported depression predicted self-reported HRQoL (R2?=?0.79, F [1, 10]?=?33.48, p<0.001), but age at injury did not (R2?=?0.19, F [1, 10]?=?2.09, p?=?0.18). Conclusions: Our results suggest that depression is a predictor of health related quality of life in youth post-TBI. The possibility of using targeted assessment and therapy for depression post-TBI to improve health related quality of life should be explored. PMID:25010719

Hispanic Americans Baseline Alcohol Survey (HABLAS): Alcohol-Related Problems Across Hispanic National Groups*  

PubMed Central

Objective: The purpose of this study was to examine the prevalence and correlates of alcohol-related problems across four Hispanic national groups: Mexican Americans, Puerto Ricans, Cuban Americans, and South/Central Americans. Method: Using a multistage cluster sample design, 5,224 individuals ages 18 years and older were selected from the household population of five U.S. metropolitan areas: Miami, New York, Philadelphia, Houston, and Los Angeles. Results: Cuban Americans had the lowest prevalence of alcohol-related problems. Significant differences across national group for zero versus two or more problems and for one versus two or more problems existed among men. Puerto Rican women were most likely to report two or more problems. The presence of zero versus two or more problems varied significantly across groups. There was variation in problem type across national groups among both men and women. Regression analyses showed that all groups were more likely than Cuban Americans to report two or more problems (vs zero) (Puerto Ricans: odds ratio [OR] = 2.02, p < .05; Mexican Americans: OR = 2.92, p ? .01; South/Central Americans: OR = 2.12, p ? .01). Being U.S. born (vs foreign born) increased the likelihood of experiencing one (OR = 1.57, p < .05) and two or more problems (OR = 1.95, p ? .01). The volume of consumption was associated with problems (one problem: OR = 1.16, p ? .01; two or more problems: OR = 1.31, p ? .01). Heavy episodic drinking less than once a month was associated with two or more problems (OR= 6.15, p ? .01). Heavy episodic drinking one or more times a month was associated with one problem (OR = 1.74, p ? .01) and two or more problems (OR = 3.18, p ? .01). Conclusions: It is important to recognize that Hispanics are not a homogenous group. PMID:19895778

[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

Quality of life related to swallowing in Parkinson's disease.  

PubMed

Swallowing difficulties in Parkinson's disease can result in decreased quality of life. The swallowing quality of life questionnaire (SWAL-QOL) is an instrument for specifically assessing quality of life with respect to swallowing, which has been little explored in patients with Parkinson's disease (PD). The goal of this study was to evaluate the quality of life with respect to swallowing in persons with PD compared to controls and at several stages of the disease using the SWAL-QOL. The experimental group was composed of 62 persons with PD at stages 1-4. Forty-one age-matched healthy subjects constituted the control group. The SWAL-QOL scores were significantly lower for the patients with PD than for the controls in all SWAL-QOL domains. Eating duration had the largest difference in score between persons with PD and the controls and the lowest mean score, followed by communication, fatigue, fear, sleep, and food selection. The scores of most domains were lower at later stages of the disease. The scores for eating duration, symptom frequency, and sleep were significantly lower at stage 4 than stages 1 and 2. In conclusion, patients with PD have significantly lower scores in all domains of the SWAL-QOL than normal controls. This means swallowing difficulties occurring in patients with PD negatively affect their QOL. Progression of the disease worsens swallowing QOL, more specifically in the domains of eating duration, symptom frequency, and sleep. This occurs mostly at later stages of the disease. PMID:24952632

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

Health-related quality of life and symptom research in glioblastoma multiforme patients.  

PubMed

Health-related quality of life is increasingly becoming an important end point in cancer research. Until recently, relatively little was known about the health-related quality of life of glioblastoma multiforme patients. This is due to the relative scarcity of this disease compared with other cancers and its dismal prognosis. Now, there is progress in the treatment of this tumor: new (combination) treatments will be studied in randomized trials and health-related quality will be incorporated as a (secondary) end point next to progression-free survival. Glioblastoma multiforme patient health-related quality of life may also have prognostic significance and may, therefore, be used with the individual patient to tailor treatment. This review aims to chart the history of glioblastoma multiforme and treatment, reporting on the latest health-related quality of life tools and research findings. PMID:19807618

Drinking motives as moderators of the effect of ambivalence on drinking and alcohol-related problems.  

PubMed

The current study seeks to evaluate relationships between drinking motives and alcohol-related ambivalence in the prediction of problem drinking. We expected that: 1) main effects would emerge such that alcohol-related ambivalence would be positively associated with peak drinking and problems; drinking motives would be positively associated with drinking and problems, and 2) interactions would emerge between motives and ambivalence in predicting problematic drinking such that drinking motives would be positively associated with peak drinking and problems, especially among those high in ambivalence over drinking. Six hundred sixty-nine undergraduate students (mean age=22.95, SD=5.47, 82.22% female) completed study materials. Results showed that consistent with expectations, ambivalence was positively associated with peak drinking and problems. Further, consistent with expectations, drinking motives were positively associated with peak drinking and problems. Additionally, ambivalence was positively associated with drinking motives. Significant interactions emerged between drinking motives (social and coping) and ambivalence when predicting peak drinking and alcohol-related problems. These findings highlight the importance of considering motives in the relationship between ambivalence and drinking. Clinical implications include the need for tailoring interventions to target individual difference factors that increase risk for heavy drinking and associated problems. This is especially important among college students who may be at risk for problematic behavior. PMID:24094922

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.

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. PMID:21984861

Comparing Cognitive, Relational and Stress Mechanisms Underlying Gender Differences in Recovery from Bereavement-related Internalizing Problems

Four putative mediators underlying gender differences in youths’ recovery from bereavement-related internalizing problems were examined in a sample (N = 109; age range of 8 to 16 years at the initial assessment) of parentally-bereaved youth: intrusive thoughts about grief, post-death stressors, negative appraisals of post-death stressors and fear of abandonment. A three-wave parallel process longitudinal growth model design was employed. Changes in internalizing problems and mediators were measured as a function of months since the death. Girls showed stability in depression symptoms and a slight rise in anxiety symptoms; boys’ trajectories of symptoms of anxiety and depression declined. Girls’ higher initial levels of post-death stressors, threat appraisals and fear of abandonment mediated their higher level of internalizing problems 14 months later. Girls’ higher initial fear of abandonment also mediated additional growth in anxiety relative to boys. PMID:20183636

Provider workload and quality of care in primary care settings: moderating role of relational climate.  

PubMed

Primary care providers are increasingly under pressure to do more with fewer resources. We examined the effect of workload on patients' experiences of quality of care, measured through approximately 44,000 patient experience surveys in a sample of 222 primary care clinics in the Veterans Health Administration. We tested the extent to which relational climate, a measure of teamwork, moderated the relationship between workload and patient ratings of quality of care. Our outcome measures included patient complaints, time spent with provider, and overall visit quality. Workload was negatively associated with patients' quality of care ratings and relational climate moderated the relation between workload and quality of care ratings. Patients seen in clinics with higher workload and greater relational climate reported better care compared with patients in clinics with higher workload but lower relational climate. Findings highlight the importance of relational climate as an important teamwork factor when managing and developing clinic policies, practices, and procedures in resource-constrained settings.

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.

Predictors of Alcohol-Related Problems Among Depressed and Non-Depressed Women  

PubMed Central

Background Depression and alcohol-related problems are often comorbid in women, but not all depressed women have comorbid alcohol-related problems. The current study investigated intrapersonal (drinking expectancies), interpersonal (interpersonal pressure to drink), and familial (mother’s and father’s drinking history) predictors of alcohol-related problems among women with and without a major depressive episode in the past year. Method Participants were 853 women ages 21–90 from a U.S. national probability sample. Depression diagnosis was determined via interviewer administration of the Diagnostic Interview Schedule (DIS) depression module. Participants completed self-report measures of alcohol-related problems and intrapersonal, interpersonal, and familial predictors of drinking. Results Regression analyses indicated that an episode of depression in the past year, more positive drinking expectancies, greater interpersonal pressure to drink, and higher levels of maternal (but not paternal) drinking predicted alcohol-related problems; moreover, the relationships between alcohol-related problems and maternal drinking, paternal drinking, and interpersonal pressure to drink were significantly stronger among women with an episode of major depression in the past year than among women without an episode. Limitations Study data was cross-sectional and obtained through self-report, thus limiting causal explanations of results. Conclusions Findings suggest that depression may enhance the impact of interpersonal and familial risk factors on women’s alcohol misuse. Implications of findings for transdiagnostic models of psychopathology and for prevention and treatment of alcohol-related problems in women presenting with depressive symptoms are discussed.

Siblings exposed to intimate partner violence: linking sibling relationship quality & child adjustment problems.  

PubMed

Although the majority of families that experience intimate partner violence (IPV) have more than one child, most research to date has focused upon a single child within these families. A significant body of research has indicated siblings play an important role in children's adjustment and well-being. To address this gap, the three main goals of the present study were to compare the adjustment of older and younger siblings exposed to IPV, to describe and compare the quality of these sibling relationships from multiple perspectives, and to investigate how sibling adjustment and relationship quality influence children's adjustment. Forty-seven sibling pairs and their mothers were recruited from the community. Mothers self-reported on their violent experiences using the Conflict Tactics Scale, and also estimated the length of time their children were exposed to IPV. Mothers and children completed assessments of child adjustment and the quality of sibling relationships. Observers also assessed the quality of sibling interaction. Results indicated that adjustment between siblings was highly inter-related. On average, mothers reported sibling relationships as less positive but also as less hostile than did siblings themselves. Higher levels of sibling hostility, lower levels of sibling warmth and higher levels of disengagement each significantly predicted child adjustment; however, these effects were predicated upon the adjustment of the other sibling. The sibling relationships of children exposed to IPV made a difference in their individual adjustment, and their adjustment issues influenced how they feel about and interacted with their sibling. Sibling hostility played a stronger role in adjustment issues than sibling warmth. The nature of sibling influences and the direction of future research were discussed. PMID:24021818

Ecosystem attributes related to tidal wetland effects on water quality.  

PubMed

Biogeochemical functioning of ecosystems is central to nutrient cycling, carbon balance, and several ecosystem services, yet it is not always clear why levels of function might vary among systems. Wetlands are widely recognized for their ability to alter concentrations of solutes and particles as water moves through them, but we have only general expectations for what attributes of wetlands are linked to variability in these processes. We examined changes in several water quality variables (dissolved oxygen, dissolved organic carbon, nutrients, and suspended particles) to ascertain which constituents are influenced during tidal exchange with a range of 17 tidal freshwater wetlands along the Hudson River, New York, USA. Many of the constituents showed significant differences among wetlands or between flooding and ebbing tidal concentrations, indicating wetland-mediated effects. For dissolved oxygen, the presence of even small proportional cover by submerged aquatic vegetation increased the concentration of dissolved oxygen in water returned to the main channel following a daytime tidal exchange. Nitrate concentrations showed consistent declines during ebbing tides, but the magnitude of decline varied greatly among sites. The proportional cover by graminoid-dominated high intertidal vegetation accounted for over 40% of the variation in nitrate decline.

[Epidemiology of problems related to drugs and devices in nursing homes in various regions of Italy].  

PubMed

The premises, questions and methodological problems of a multicentre study aimed at describing the epidemiology of patients' problems that require a nursing intervention are described. The main points and methodological challenges are presented and discussed: (a.) the choice of focusing on patients cared for in Nursing homes and districts because a. they are complex, originate very high nursing workload, b. few studies and data from the nursing point of view are produced; c. information on everyday care and problems are lacking, d. they are marginal populations both in research and organization of care; (b.) the need of involving nurses in a surveillance exercise, to increase the attention on problems, their causes and potential avoidability, focusing the attention on problems related to drugs and devices; (c.) the importance-and challenge- of describing what happens in everyday' care, taking in account the variability related to contexts and people. The recognition of a problem is, in fact, related to factors such as the knowledge of the patient and his/her story, the level of knowledge and expertise of the nurse, the attention paid, the context and the organization. The main lessons learned are summarised. PMID:18051620

The Problem of Time and Quantum Cosmology in the Relational Particle Mechanics Arena  

E-print Network

This article contains a local solution to the notorious Problem of Time in Quantum Gravity at the conceptual level and which is actually realizable for the relational triangle. The Problem of Time is that `time' in GR and `time' in ordinary quantum theory are mutually incompatible notions, which is problematic in trying to put these two theories together to form a theory of Quantum Gravity. Four frontiers to this resolution in full GR are identified, alongside three further directions not yet conquered even for the relational triangle. This article is also the definitive review on relational particle models originally due to Barbour (2003: dynamics of pure shape) and Barbour and Bertotti (1982: dynamics of shape and scale). These are exhibited as useful toy models of background independence, which I argue to be the `other half' of GR to relativistic gravitation, as well as the originator of the Problem of Time itself. Barbour's work and my localized extension of it are shown to be the classical precursor of the background independence that then manifests itself at the quantum level as the full-blown Problem of Time. In fact 7/8ths of the Isham--Kuchar Problem of Time facets are already present in classical GR; even classical mechanics in relational particle mechanics formulation exhibits 5/8ths of these! In addition to Isham, Kuchar and Barbour, the other principal authors whose works are drawn upon in building this Problem of Time approach are Kendall (relational models only: pure-shape configuration spaces), Dirac, Teitelboim and Halliwell (Problem of Time resolving components). The recommended scheme is a combination of the Machian semiclassical approach, histories theory and records theory.

Weight, inflammation, cancer-related symptoms and health-related quality of life among breast cancer survivors  

PubMed Central

Maintaining weight is important for better prognosis of breast cancer survivors. The associations between weight and cancer-related symptoms are not known. We examined associations among weight, weight change, inflammation, cancer-related symptoms, and health-related quality of life (HRQOL) in a cohort of stage 0-IIIA breast cancer survivors. Participants were recruited on average 6 months (2–12 months) after diagnosis. Height, weight, and c-reactive protein (CRP) were assessed at approximately 30 months post-diagnosis; cancer-related symptoms (chest wall and arm symptoms, vasomotor symptoms, urinary incontinence, vaginal symptoms, cognition/mood problems, sleep, sexual interest/function), and HRQOL (SF-36) were assessed at approximately 40 months post-diagnosis. Weight was measured at baseline in a subset. Data on 661 participants were evaluable for body mass index (BMI); 483 were evaluable for weight change. We assessed associations between BMI (<25.0, 25.0–29.9, ?30.0 kg/m2), post-diagnosis weight change (lost ?5%, weight change <5%, gained ?5%), and CRP (tertile) with cancer-related symptoms and HRQOL using analysis of covariance (ANCOVA). Higher symptoms scores indicate more frequent or severe symptoms. Higher HRQOL scores indicate better HRQOL. Compared with those with BMI<25kg/m2, women with BMI ?30 kg/m2 had scores that were: increased for arm symptoms (+25.0%), urinary incontinence (+40.0%), tendency to nap (+18.9%) and poorer physical functioning (?15.6%, all p<0.05). Obese women had lower scores in trouble falling asleep (?9.9%; p<0.05). Compared with weight change <5%, participants with ?5% weight gain had lower scores in physical functioning (?7.2%), role-physical (?15.5%) and vitality (?11.2%), and those with weight loss ?5% had lower chest wall (?33.0%) and arm symptom scores (?35.5%, all p<0.05). Increasing CRP tertile was associated with worse scores for chest wall symptoms, urinary incontinence, physical functioning, role-physical, vitality and physical component summary scores (all Ptrend<0.05). Future studies should examine whether interventions to maintain a healthy weight and reduce inflammation could alleviate cancer-related symptoms and improve HRQOL. PMID:23797178

The arithmetic problem size effect in children: an event-related potential study  

PubMed Central

This study used for the first time event-related potentials (ERPs) to examine the well-known arithmetic problem size effect in children. The electrophysiological correlates of this problem size effect have been well documented in adults, but such information in children is lacking. In the present study, 22 typically developing 12-year-olds were asked to solve single-digit addition problems of small (sum ? 10) and large problem size (sum > 10) and to speak the solution into a voice key while ERPs were recorded. Children displayed similar early and late components compared to previous adult studies on the problem size effect. There was no effect of problem size on the early components P1, N1, and P2. The peak amplitude of the N2 component showed more negative potentials on left and right anterior electrodes for large additions compared to small additions, which might reflect differences in attentional and working memory resources between large and small problems. The mean amplitude of the late positivity component which follows the N2, was significantly larger for large than for small additions at right parieto-occipital electrodes, in line with previous adult data. The ERPs of the problem size effect during arithmetic might be a useful neural marker for future studies on fact retrieval impairments in children with mathematical difficulties. PMID:25309405

Oral health-related quality of life among Brazilian dental students.  

PubMed

This study was conducted to assess oral health-related quality of life (OHRQoL) among Brazilian dental students. A cross-sectional study was carried out involving 300 dental students at the Federal University of Parana, Brazil. To measure OHRQoL, the Oral Health Impact Profile (OHIP-14) was self-administered and a questionnaire was filled out addressing socio-demographic characteristics, health-related aspects and dental experience. Descriptive analysis was performed and both univariate and multivariate Poisson regression with robust variance were used to determine associations between OHRQoL and the covariables. The prevalence of reported impact on OHRQoL was 45 percent. The mean OHIP-14 score was 4.5. In the univariate analysis, the reason for the last visit to the dentist (p = 0.004), reported discomfort in teeth/mouth (p < 0.001) and both self-rated general (p = 0.011) and oral (p < 0.001) health were significantly associated with OHRQoL. The year of academic education was not associated with OHRQoL (p = 0.712). In the multivariate model, students who reported dissatisfaction with their teeth (PR = 1.32; IC 95%: 1.01-1.73), dental pain/sensitivity (PR = 2.36; IC 95%: 1.63-3.40), esthetic dental problems (PR = 1.45; IC 95%: 1.10-1.89), restorative needs (PR = 1.60; IC 95%: 1.01-2.55) and whose last visit to the dentist was for curative treatment (PR = 1.36; IC 95%: 1.05-1.76) had greater impact on OHRQoL. Aspects related to previous dental experience and self-reported oral health problems were associated with OHRQoL. PMID:24303730

The development of personality extremity from childhood to adolescence: relations to internalizing and externalizing problems.  

PubMed

This study investigated the development of personality extremity (deviation of an average midpoint of all 5 personality dimensions together) across childhood and adolescence, as well as relations between personality extremity and adjustment problems. For 598 children (mean age at Time 1 = 7.5 years), mothers and fathers reported the Big Five personality dimensions 4 times across 8 years. Children's vector length in a 5-dimensional configuration of the Big Five dimensions represented personality extremity. Mothers, fathers, and teachers reported children's internalizing and externalizing problems at the 1st and final measurement. In a cohort-sequential design, we modeled personality extremity in children and adolescents from ages 6 to 17 years. Growth mixture modeling revealed a similar solution for both mother and father reports: a large group with relatively short vectors that were stable over time (mother reports: 80.3%; father reports: 84.7%) and 2 smaller groups with relatively long vectors (i.e., extreme personality configuration). One group started out relatively extreme and decreased over time (mother reports: 13.2%; father reports: 10.4%), whereas the other group started out only slightly higher than the short vector group but increased across time (mother reports: 6.5%; father reports: 4.9%). Children who belonged to the increasingly extreme class experienced more internalizing and externalizing problems in late adolescence, controlling for previous levels of adjustment problems and the Big Five personality dimensions. Personality extremity may be important to consider when identifying children at risk for adjustment problems. PMID:24295382

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.

Correlates of health-related quality of life in upper aerodigestive tract cancer patients.  

PubMed

Reflecting a limited understanding of the definition and determinants of health-related quality of life (HRQoL), the majority of research in this field has concentrated upon the effect of disease- and treatment-related variables. That work specifically investigating HRQoL among upper aerodigestive tract (UADT) cancer patients is no exception to this observation. Treating subject-related and non-subject-related variables separately, the aim of this study was to investigate predictors of global HRQoL rating in a sample of UADT cancer patients, concentrating upon the relative importance of sociodemographic and clinical variables. A cross-sectional study design was used with a sample of 188 UADT cancer patients. Global HRQoL was assessed using the EORTC QLQ-C30 instrument, global domain (global QoL). Other study variables were collected by subject interview and chart review. Two multivariate regression models were independently developed, containing, respectively, subject-rated and non-subject rated variables. In the model containing subject-rated predictors of global QoL, emotional, breathing, physical, financial, pain and appetite problems were significant predictors (F = 14.6, p < 0.0001 and r2 = 0.54). Among non-subject-rated sociodemographic and clinical variables tested, unemployment, older age, female gender, being dentate and a more advanced disease stage predicted worse global QoL rating, while oral as opposed to pharyngeal or laryngeal cancer predicted a better global QoL rating (F = 5.1, p < 0.0001 and r2 = 0.21). In the latter model, a greater proportion of the variance was explained by sociodemographic variables than by clinical variables. PMID:10097620

Detection of medication-related problems in hospital practice: a review  

PubMed Central

This review examines the effectiveness of detection methods in terms of their ability to identify and accurately determine medication-related problems in hospitals. A search was conducted of databases from inception to June 2012. The following keywords were used in combination: medication error or adverse drug event or adverse drug reaction, comparison, detection, hospital and method. Seven detection methods were considered: chart review, claims data review, computer monitoring, direct care observation, interviews, prospective data collection and incident reporting. Forty relevant studies were located. Detection methods that were better able to identify medication-related problems compared with other methods tested in the same study included chart review, computer monitoring, direct care observation and prospective data collection. However, only small numbers of studies were involved in comparisons with direct care observation (n = 5) and prospective data collection (n = 6). There was little focus on detecting medication-related problems during various stages of the medication process, and comparisons associated with the seriousness of medication-related problems were examined in 19 studies. Only 17 studies involved appropriate comparisons with a gold standard, which provided details about sensitivities and specificities. In view of the relatively low identification of medication-related problems with incident reporting, use of this method in tracking trends over time should be met with some scepticism. Greater attention should be placed on combining methods, such as chart review and computer monitoring in examining trends. More research is needed on the use of claims data, direct care observation, interviews and prospective data collection as detection methods. PMID:23194349

Dimensions of disinhibited personality and their relation with alcohol use and problems  

PubMed Central

Although alcohol use disorders (AUDs) have been associated with different aspects of disinhibited personality and antisociality, less is known about the specific relationships among different domains of disinhibited personality, antisociality, alcohol use, and alcohol problems. The current study was designed to address three goals, (i) to provide evidence of a three-factor model of disinhibited personality (comprised of impulsivity [IMP], risk taking/ low harm avoidance [RTHA], excitement seeking [ES]), (ii) to test hypotheses regarding the association between each dimension and alcohol use and problems, and (iii) to test the hypothesis that antisociality (social deviance proneness [SDP]) accounts for the direct association between IMP and alcohol problems, while ES is directly related to alcohol use. Measures of disinhibited personality IMP, RTHA, ES and SDP and alcohol use and problems were assessed in a sample of young adults (N=474), which included a high proportion of individuals with AUDs. Confirmatory factor analyses supported a three-factor model of disinhibited personality reflecting IMP, RTHA, and ES. A structural equation model (SEM) showed that IMP was specifically associated with alcohol problems, while ES was specifically associated with alcohol use. In a second SEM, SDP accounted for the majority of the variance in alcohol problems associated with IMP. The results suggest aspects of IMP associated with SDP represent a direct vulnerability to alcohol problems. In addition, the results suggest that ES reflects a specific vulnerability to excessive alcohol use, which is then associated with alcohol problems, while RTHA is not specifically associated with alcohol use or problems when controlling for IMP and ES.

Health related quality of life in parents of six to eight year old children with Down syndrome.  

PubMed

Raising a child with Down syndrome (DS) has been found to be associated with lowered health related quality of life (HRQoL) in the domains cognitive functioning, social functioning, daily activities and vitality. We aimed to explore which socio-demographics, child functioning and psychosocial variables were related to these HRQoL domains in parents of children with DS. Parents of 98 children with DS completed the TNO-AZL adult quality of life questionnaire (TAAQOL) and a questionnaire assessing socio-demographic, child functioning and psychosocial predictors. Using multiple linear regression analyses for each category of predictors, we selected relevant predictors for the final models. The final multiple linear regression models revealed that cognitive functioning was best predicted by the sleep of the child (?=.29, p<.01) and by the parent having given up a hobby (?=-.29, p<.01), social functioning by the quality of the partner relation (?=.34, p<.001), daily activities by the parent having to care for an ill friend or family member (?=-.31, p<.01), and vitality by the parent having enough personal time (?=.32, p<.01). Overall, psychosocial variables rather than socio-demographics or child functioning showed most consistent and powerful relations to the HRQoL domains of cognitive functioning, social functioning, daily activities and vitality. These psychosocial variables mainly related to social support and time pressure. Systematic screening of parents to detect problems timely, and interventions targeting the supportive network and the demands in time are recommended. PMID:24083990

[Intercultural nursing: analysis of changes in the perception of relational problems with foreign patients].  

PubMed

Today's society is highly impacted by immigration, as well as healthcare system. It is becoming increasingly common and frequent to establish relationships with patients with different cultural backgrounds. The aim of this study is analyzing Italian nurses' perception of the relational dynamics with foreign patients, to determine its evolution, and to identify the variables which can affect the quality of care. The study is both qualitative and quantitative with descriptive aim, using a questionnaire that assesses the theoretical-practical level of preparation, both perceptive and effective, of nurses when assisting foreign patients. To evaluate the emotional and experiential impact of the relationship with foreign patients, the difficulties encountered while establishing such relationship, and the resolution strategies - both effective and potential. The sample, composed of 101 Italian nurses employed at SanRaffaele Hospital in 6 specific Operational Units, resulted in a total of 91 returned questionnaires during the period May-June 2011. The data was analyzed through statistical instruments and compared to the results of a similar study done in 2004. The experience of intercultural nursing is seen by the sample as interesting and rewarding. The vast majority of nurses have positive responses. The more frequent issues are those connected with communication with foreign patients, and those connected with the increase workload due the presence of foreign patients. Nurses responded to difficulties more with human skills than with specific abilities, and tend to delegate the problem to the Cultural Mediation service. This new issue has a very high impact on nurses. The emerged difficulties have not decreased over time, this due to the lack of a proper policy within health care facilities in recent years, with the exception of a little improvement on the academic education. However the current academic education does not provide solutions useful in the everyday routing. This study, despite the small sample and a rather narrow degree of analysis, likes to draw attention on the topic both of nurses and on health care facilities managerial team in order to develop a effective startegie to deal with the emerged issues.

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.

Solutions of the benchmark problems by the dispersion-relation-preserving scheme  

NASA Technical Reports Server (NTRS)

The 7-point stencil Dispersion-Relation-Preserving scheme of Tam and Webb is used to solve all the six categories of the CAA benchmark problems. The purpose is to show that the scheme is capable of solving linear, as well as nonlinear aeroacoustics problems accurately. Nonlinearities, inevitably, lead to the generation of spurious short wave length numerical waves. Often, these spurious waves would overwhelm the entire numerical solution. In this work, the spurious waves are removed by the addition of artificial selective damping terms to the discretized equations. Category 3 problems are for testing radiation and outflow boundary conditions. In solving these problems, the radiation and outflow boundary conditions of Tam and Webb are used. These conditions are derived from the asymptotic solutions of the linearized Euler equations. Category 4 problems involved solid walls. Here, the wall boundary conditions for high-order schemes of Tam and Dong are employed. These conditions require the use of one ghost value per boundary point per physical boundary condition. In the second problem of this category, the governing equations, when written in cylindrical coordinates, are singular along the axis of the radial coordinate. The proper boundary conditions at the axis are derived by applying the limiting process of r approaches 0 to the governing equations. The Category 5 problem deals with the numerical noise issue. In the present approach, the time-independent mean flow solution is computed first. Once the residual drops to the machine noise level, the incident sound wave is turned on gradually. The solution is marched in time until a time-periodic state is reached. No exact solution is known for the Category 6 problem. Because of this, the problem is formulated in two totally different ways, first as a scattering problem then as a direct simulation problem. There is good agreement between the two numerical solutions. This offers confidence in the computed results. Both formulations are solved as initial value problems. As such, no Kutta condition is required at the trailing edge of the airfoil.

Sy05-2alcohol-related problems after hanshin awaji earthquake.  

PubMed

In the early morning on Jan. 17, 1995, a mega earthquake attacked Kobe city, Hanshin area and Awaji Island. Over 6,400 people died, 40,000 people were injured, 249,000 buildings were destroyed and the estimated economic impact was 100 billion dollars. Many people with drinking problem in the stricken area were affected by the disaster. Over 300,000 people lost their home and lived in shelters immediately after the earthquake. By the Emergency Psychiatric Clinic report (from Jan. 1995 to Mar. 1995), 7.3 percent of patient of clinics were substance use disorder. In Suma-ward, 10 percent of all cases and 23 percent of hospitalized cases are alcohol use disorder. From Apr. 1995, 48,000 temporary housing were built, where high prevalence of alcohol related problem was reported. From 1995 to 1998, 204 "kodokushi" (dying without a witness) cases were reported in the temporary housing and a half or one third of these cases were estimated to be related to heavy use of alcohol. Disaster Victim Assistance Program reported that 17 percent of services about male victims were alcohol problem. Although alcohol consumption in the stricken area after the earthquake did not increase, the need of the variety of services for alcohol-related problems increased. PMID:25221321

Association between work-related health problems and job insecurity in permanent and temporary employees  

PubMed Central

Objectives This research was conducted with an aim of determining the correlation between job insecurity and an employee’s work-related health problems among permanent and temporary workers. Methods Using the data from the First Korean Working Conditions Survey conducted in 2006, a total of 7,071 workers, excluding employers and the self-employed, were analyzed. Work-related health problems were categorized as backache, headache, abdominal pain, muscular pain, stress, fatigue, insomnia, anxiety or depression. Each problem was then analyzed for its relationship to job insecurity through logistic regression analysis. Results Among the 7,071 workers, 5,294 (74.9%) were permanent workers and 1,777 (25.1%) were temporary workers. For the permanent workers, presence of high or moderate job insecurity appeared more closely linked to backache, headache, abdominal pain, muscular pain, stress, fatigue, insomnia, anxiety, and depression compared to absence of job insecurity. However, for the temporary workers, only depression appeared to be associated with the presence of high job insecurity. Conclusion The study showed that the presence of job insecurity is correlated with work-related health problems. The deleterious effects of job insecurity appeared to be stronger in permanent than temporary workers. Additional research should investigate ways to effectively reduce job insecurity. PMID:24472497

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. PMID:19297882

Effects of qigong training on health-related quality of life, functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer: a pilot study.  

PubMed

This study aimed to investigate the effects of Qigong intervention on quality of life (QOL), health-related functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer (NPC). Twenty-five survivors of NPC were included in the experimental group (mean age ± SD: 55.4 ± 7.5 years) and 27 in the control group (mean age ± SD: 58.7 ± 9.5 years). The experimental group underwent a weekly 1.5-hour Qigong training program and an identical home program (three times/week) for six months. The control group received no training. Global health status/QOL, functioning, and cancer-related symptoms were assessed by the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-H&N35 questionnaires before training began, after three months of Qigong training, at the end of the six-month Qigong intervention (i.e., posttest), and six months posttest. Intention-to-treat analysis revealed no statistically (P > 0.05) or clinically significant improvement in global health status/QOL, functioning, or symptoms in either group. The experimental group had 45.8% fewer sense-related (smell and taste) problems (P < 0.05) but 98.6% more speech-related problems (P < 0.05) than the control group after the Qigong intervention. Qigong training resulted in no apparent improvement in health-related QOL, functionality, or cancer-related symptoms in cancer-free survivors of NPC, except for a possible reduction in smell- and taste-related 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. PMID:21779325

Relations Among Positive Parenting, Children's Effortful Control, and Externalizing Problems: A Three-Wave Longitudinal Study  

PubMed Central

In a 3-wave longitudinal study (with assessments 2 years apart) involving 186 early adolescents (M ages of approximately 9.3, 11.4, and 13.4), the hypothesis that parental warmth/positive expressivity predicts children’s effortful control (EC) (a temperamental characteristic contributing to emotion regulation) 2 years later, which in turn predicts low levels of externalizing problems another 2 years later, was examined. The hypothesis that children’s EC predicts parenting over time was also examined. Parents were observed interacting with their children; parents and teachers reported children’s EC and externalizing problems; and children’s persistence was assessed behaviorally. Children’s EC mediated the relation between positive parenting and low levels of externalizing problems (whereas there was no evidence that children’s EC predicted parenting). PMID:16150002

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. PMID:23786966

Parental knowledge and adolescent adjustment: substance use and health-related quality of life.  

PubMed

This study analyses two models (maternal and paternal) in which parental care and sources of parental knowledge moderated the relationship between parents' knowledge about their adolescents' lives and adolescents' substance use and health-related quality of life. The sample was made up of 15942 Spanish adolescents who participated in the 2006 edition of Health Behavior in School-aged Children Study. Results showed that increased parents' knowledge about their adolescents' lives reduced adolescents' substance use and increased their quality of life. With respect to the moderation relationship, a limited effect was found. However, parental care and sources of parental knowledge used by both parents generally had main effects on adolescents' substance use and health-related quality of life, with care being the most relevant variable in the health-related quality of life, while knowledge was the most relevant one for substance use.

Funding Source and Research Report Quality in Nutrition Practice-Related Research  

PubMed Central

Background The source of funding is one of many possible causes of bias in scientific research. One method of detecting potential for bias is to evaluate the quality of research reports. Research exploring the relationship between funding source and nutrition-related research report quality is limited and in other disciplines the findings are mixed. Objective The purpose of this study is to determine whether types of funding sources of nutrition research are associated with differences in research report quality. Design A retrospective study of research reporting quality, research design and funding source was conducted on 2539 peer reviewed research articles from the American Dietetic Association's Evidence Analysis Library® database. Results Quality rating frequency distributions indicate 43.3% of research reports were rated as positive, 50.1% neutral, and 6.6% as negative. Multinomial logistic regression results showed that while both funding source and type of research design are significant predictors of quality ratings (?2?=?118.99, p<0.001), the model's usefulness in predicting overall research report quality is little better than chance. Compared to research reports with government funding, those not acknowledging any funding sources, followed by studies with University/hospital funding were more likely to receive neutral vs positive quality ratings, OR?=?1.85, P <0.001 and OR?=?1.54, P<0.001, respectively and those that did not report funding were more likely to receive negative quality ratings (OR?=?4.97, P<0.001). After controlling for research design, industry funded research reports were no more likely to receive a neutral or negative quality rating than those funded by government sources. Conclusion Research report quality cannot be accurately predicted from the funding source after controlling for research design. Continued vigilance to evaluate the quality of all research regardless of the funding source and to further understand other factors that affect quality ratings are warranted. PMID:22163017

Investigating grade nine textbook problems for characteristics related to mathematical literacy  

NASA Astrophysics Data System (ADS)

This study presents a content analysis of the new Iranian Grade 9 mathematics textbook and two Australian Year 9 mathematics textbooks, examining the extent to which the problems show characteristics associated in the literature with promoting mathematical literacy. The new Iranian book was produced to meet a range of needs including several well aligned with mathematical literacy for all students. Australia was selected as the comparison country because of its relatively high international achievement in mathematical literacy. Three comparable chapters in each book were analysed for these characteristics. When considering the percentages of problems showing each characteristic, there was considerable similarity between the textbooks. However, the Australian mathematics textbooks contain many more problems than the Iranian textbook and each chapter includes problems in a diverse range of contexts and the mathematical tasks range from simple applications of formulas to real world modelling although of a constrained nature. With many fewer problems, the Iranian textbook has considerably less diversity of context and very little opportunity for students to engage in mathematical modelling, the key process of mathematical literacy.

Pain in the obese: impact on health-related quality-of-life.  

PubMed

Obesity is a major public health problem associated with increased health risks, chronic pain, and decrements in functional health status and subjective well-being. To examine the impact of pain on Health-Related Quality-of-Life (HRQL). 312 consecutive persons seeking medically-supervised weight loss treatment completed a sociodemographic questionnaire, the Medical Outcomes Study Short-Form Health Survey (SF-36), and underwent a series of clinical evaluations. Forty-eight percent of the patients when asked to rate "How much pain have you had in the last four weeks?" reported at least moderate pain in the four weeks prior to treatment. In analyses adjusted for sociodemographic factors, body-mass index (BMI) (kg/m2), and depression, obese patients reporting pain scored significantly lower on all SF-36 domains than those not reporting pain. Findings indicate that the pain itself is independently associated with impaired HRQL in nearly half of obese persons seeking treatment. These data demonstrate that pain is a strong covariate of obesity and, therefore, may need to be considered in the design and development of obesity treatments. PMID:9706368

Health-Related Quality of Life in Cervical Cancer Survivors: A Population-Based Survey  

SciTech Connect

Purpose: In a population-based sample of cervical cancer survivors, health-related quality of life (HRQoL) was assessed 2-10 years postdiagnosis. Methods and Materials: All patients given a diagnosis of cervical cancer in 1995-2003 in the Eindhoven region, The Netherlands, and alive after Jan 2006 were identified through the cancer registry. Generic HRQoL (36-Item Short-Form Health Survey, EQ-5D), cervical cancer-specific HRQoL (European Organization for Research and Treatment of Cancer Quality-of-Life questionnaire cervical cancer module), and anxiety (6-item State Trait Anxiety Inventory) were assessed and compared with a reference population (n = 349). Data for tumor characteristics at diagnosis and disease progression were available. Results: A total of 291 women responded (69%), with a mean age of 53 {+-} 13 (SD) years (range, 31-88 years). Treatment had consisted of surgery (n = 195) or a combination of therapies (n = 75); one woman had not been treated. Of all women, 85% were clinically disease free, 2% had a recurrence/metastasis, and in 13%, this was unknown. After controlling for background characteristics (age, education, job and marital status, having children, and country of birth), generic HRQoL scale scores were similar to the reference population, except for worse mental health in survivors. The most frequent symptoms were crampy pain in the abdomen or belly (17%), urinary leakage (15%), menopausal symptoms (18%), and problems with sexual activity. Compared with the 6-10-year survivors, more sexual worry and worse body image were reported by the 2-5-year survivors. Compared with surgery only, especially primary radiotherapy was associated with an increased frequency of treatment-related side effects, also after controlling for age and disease stage at diagnosis and follow-up. Conclusions: Most cervical cancer survivors were coping well, although their mental health was worse than in the reference population. Even after 2-10 years, radiotherapy was associated with an increased frequency of treatment-related side effects.

Referential integrity is used in relational data-bases for expressing existence dependencies between tuples. Relational database management systems (RDBMS) provide diverse referential integrity capabilities. Thus, is some RDBMSs referential integrity constraints can be specified non-procedurally (declaratively), while in other RDBMSs they must be specified procedurally. Moreover, some RDBMSs restrict the class of allowed referential integrity constraints. We examine in this paper the main problems underlying the use of referential integrity mechanisms in three representative RDBMSs, DB2, SYBASE, and INGRES. 11 refs.

Quality of life in relation to social and disease factors in patients with type 2 diabetes in Lithuania  

PubMed Central

Background Diabetic patients are more than twice as costly to manage as non-diabetic patients, due mainly to the high costs associated with management of diabetic complications. As in most nations of the world, the number of patients with DM is increasing every year in Lithuania. The aim of this study was to determine relation between quality of the life and disease and social factors of patients with type 2 diabetes in Lithuania. Material/Methods Independently prepared questions about the subjects of the survey were: gender; age; weight; education; social and marital status; duration of the disease (in years); treatment method; complications; morbidity with arterial hypertension; change in dietary habits after diagnosis of diabetes (started to eat accordingly to recommendations of the therapist); how often nourishment is taken accordingly to recommendations of the therapist; if beginning to exercise after diagnosis of the diabetes; and if exercising, exercises at least 2–3 times per week. Body mass index was calculated as the relation between body mass in kg and height m square (BMI=kg/m2). The hospital anxiety and depression (HAD) scale was used for the evaluation of depression and anxiety. Quality of life of patients was evaluated with the SF-36 questionnaire. We surveyed 1022 patients with type 2 diabetes (372 men and 650 women). Association between quality of the life and explanatory parameters (disease and social factors) were analyzed using the logistic regression analysis model. Results We found that women had lower scores than men in all fields of quality of life (p<0.001). Peroral treatment had a positive impact on the quality of life (QL) fields of the role limitations due to emotional problems (ORa 0.16. 95% CI 0.07–0.34; p<0.001). Treatment with insulin had a positive effect on restriction of activity because of emotional problems (ORa ? 0.23. 95% CI 0.11–0.49; p<0.001) and mental health (ORa ? 0.38. 95% CI 0.19–0.78; p=0.008), but had a negative impact on bodily pain (ORa ? 3.95. 95% CI 1.41–11.09; p=0.009) and physical health (ORa ? 4.14. 95% CI 2.03–8.47; p<0.001). Conclusions Age and BMI are less important factors that can influence quality of life. Peroral treatment positively acted on the role limitations due to emotional problems, bodily pain, and mental health, but had a strong negative effect on emotional state. PMID:23462804

Objectives One of the most referenced theoretical frameworks to measure Health Related Quality of Life (HRQoL) is the Wilson and Cleary framework. With some adaptions this framework has been validated in the adult population, but has not been tested in pediatric populations. Our goal was to empirically investigate it in children. Methods The contributory factors to Health Related Quality of Life that we included were symptom status (presence of chronic disease or hospitalizations), functional status (developmental status), developmental aspects of the individual (social-emotional) behavior, and characteristics of the social environment (socioeconomic status and area of education). Structural equation modeling was used to assess the measurement structure of the model in 214 German children (3–5 years old) participating in a follow-up study that investigates pediatric health outcomes. Results Model fit was ?2?=?5.5; df?=?6; p?=?0.48; SRMR ?=?0.01. The variance explained of Health Related Quality of Life was 15%. Health Related Quality of Life was affected by the area education (i.e. where kindergartens were located) and development status. Developmental status was affected by the area of education, socioeconomic status and individual behavior. Symptoms did not affect the model. Conclusions The goodness of fit and the overall variance explained were good. However, the results between children' and adults' tests differed and denote a conceptual gap between adult and children measures. Indeed, there is a lot of variety in pediatric Health Related Quality of Life measures, which represents a lack of a common definition of pediatric Health Related Quality of Life. We recommend that researchers invest time in the development of pediatric Health Related Quality of Life theory and theory based evaluations. PMID:25415751

A Genetic Algorithm for Job-Shop Problems with Various Schedule Quality Criteria  

Microsoft Academic Search

Much recent research has investigated the use of genetic algorithms (GAs) in job-shop scheduling. Mostly, this has involved comparison or construction of ingenious reprsentations and operators in the context of finding a schedule which minimises makespan. Many more criteria exist with which to judge schedule quality, however. Often, makespan may be a low priority aspect of schedule quality, We describe

Transport and its energy-related air pollution problems in Bangkok  

SciTech Connect

Suspended Particulate Matter (SPM) is a major pollutant, followed by carbon monoxide and lead, as the ambient levels of these pollutants all exceed international standards such as those laid down by the World Health Organization (WHO). In order to meet these standards, it is necessary to reduce the emissions of these pollutants by 84.9%, 47.3%, and 13.0% respectively. Ambient air quality in Bangkok will continue to deteriorate to an unacceptable level by the year 2000, if no action is taken over and above implementation of already approved projects (including mass transit projects). Carbon monoxide and hydrocarbon emissions could be reduced by 28 and 22% respectively, with the implementation of Reasonable Technology Measures used to control vehicle emissions alone. These measures include inspection and maintenance programs. Their success is dependent on effective quality control and on the application of stringent standards. However, these measures would have little impact in reducing the emissions of SPM. It can therefore be concluded that Reasonable Technology Measures will be insufficient to address Bangkok`s air pollution problems, without complementary measures to reduce traffic congestion. Implementation of the traffic measures outlined under the Demand-Management Policy Scenario alone will reduce CO and HC emissions by up to 45%. These measures serve to reduce traffic congestion and increase the average travel speed. However, in order to improve air quality to internationally acceptable levels, traffic measures must be implemented in conjunction with the Reasonable Technology Scenario. This will provide an additional reduction of CO and HC emissions by 45%.

Quantity and quality of obesity-related research in Arab countries: assessment and comparative analysis  

PubMed Central

Background Obesity is a serious worldwide medical condition, considered by some researchers as one of the most serious public health problems of the 21st century. The main objective of this study was to assess the quantity and quality of obesity-related research from Arab countries and compare it with that from non-Arab Middle Eastern countries. Methods Original scientific articles or reviews published by Arab countries about obesity up until 2011 were screened using the ISI Web of Science database. Research activity was assessed by analyzing the annual research productivity, journals names, citations, top 10 active institutions, and the contribution of each Arab country to obesity research. Results The total number of original and review research articles published globally about obesity was 110,167. The leading country in obesity research was United States of America (42.47%). Turkey, Israel, and Iran were in the top 30 countries while Kingdom of Saudi Arabia (KSA), Egypt, and Kuwait ranked 39th, 43rd, and 47th, respectively. A total of 1,121 documents about “obesity” were published by Arab countries, representing 1.0% of the global research output, with 13,343 citations (average citation of 11.9 per document) and an h-index of 44. The Arab countries’ research output was very low until the mid-1990s and then increased steadily. Of the 1,121 documents, 107 (9.55%) were published in the Saudi Medical Journal. KSA, with a total of 318 publications ranked first among Arab countries in research quantity while Kuwait ranked first after adjustment based on population size. King Saud University in KSA was the most productive institution with a total of 140 documents. Compared with other non-Arab Middle Eastern countries, the research productivity from Arab countries was lower than that from Turkey, higher than that from Iran, and close to that from Israel. However, the h-index of documents about obesity published from Arab countries was lower than that of Turkey and Israel, but slightly higher than that from Iran. Conclusions The present data reveals a good contribution by some Arab countries, particularly Arab gulf countries, to obesity research. More efforts are needed by other Arab countries to bridge the gap in this topic and to improve the quality of obesity-related research originating from Arab countries. PMID:25005130

Memphis: Finding and Fixing NUMA-related Performance Problems on Multi-core Platforms  

SciTech Connect

Until recently, most high-end scientific applications have been immune to performance problems caused by Non-Uniform Memory Access (NUMA). However, current trends in micro-processor design are pushing NUMA to smaller and smaller scales. This paper examines the current state of NUMA and makes several contributions. First, we summarize the performance problems that NUMA can present for multithreaded applications and describe methods of addressing them. Second, we demonstrate that NUMA can indeed be a significant problem for scientific applications, showing that it can mean the difference between an application scaling perfectly and failing to scale at all. Third, we describe, in increasing order of usefulness, three methods of using hardware performance counters to aid in finding NUMA-related problems. Finally, we introduce Memphis, a data-centric toolset that uses Instruction Based Sampling to help pinpoint problematic memory accesses, and demonstrate how we used it to improve the performance of several production-level codes - HYCOM, XGC1 and CAM - by 13%, 23% and 24% respectively.

Drug-related problems in patients with benign prostatic hyperplasia: a cross sectional retrospective study.  

PubMed

Benign Prostatic Hyperplasia (BPH) patients are at risk of acquiring drug-related problems (DRPs), as it is present in the majority of aging men. To date, DRPs among BPH patients have not been well studied. We conducted this retrospective study in a tertiary hospital in Malaysia from January 2009 to June 2012 with the aim of identifying the factors associated with DRPs among BPH patients. The Pharmaceutical Care Network Europe Classification Version (PCNE) 5.01 was used as a tool to classify DRPs. We enrolled 203 patients from 259 hospital admissions. A total of 390 DRPs were found and there was an average of 1.5±1.3 problems per hospitalization. 76.1% of hospital admissions included at least one DRP. The most common DRP categories encountered were drug choice problems (45.9%), drug interactions (24.9%), and dosing problems (13.3%). Factors such as advanced age (p?=?0.005), a hospital stay of more than 6 days (p?=?0.001), polydrug treatments (p<0.001), multiple comorbidities (p<0.001), and comorbid cardiovascular disease (p?=?0.011), diabetes mellitus(p?=?0.001), hypertension (p<0.001) and renal impairment (p?=?0.011) were significantly associated with the occurrence of DRPs. These data indicated that the prevalence of DRPs is high among BPH patients. The identification of different subtypes of DRPs and the factors associated with DRPs may facilitate risk reduction for BPH patients. PMID:24475089

Allostasis and the development of internalizing and externalizing problems: changing relations with physiological systems across adolescence.  

PubMed

Allostasis, or the maintenance of stability through physiological change, refers to the process by which individuals adjust to the continually changing demands that are put upon somatic activity by salient events. Bauer and colleagues proposed that allostasis could be detected through patterns of the joint reactivity of the autonomic nervous system (ANS) and hypothalamic-pituitary-adrenal (HPA) axis system under stressful conditions. We examined the associations between ANS and HPA reactivity and the development of externalizing and internalizing problems over 2 years in a sample of 215 adolescents. The interactions of ANS and HPA reactivity were contemporaneously associated with, and longitudinally predictive of, adolescents' emotional and behavioral problems. Adolescents with symmetrical high reactivity across systems had more internalizing and fewer externalizing problems initially. Over time, both symmetrical and asymmetrical reactivity predicted increasing internalizing problems in girls, depending on the measure of ANS activity that was examined, heart rate, or blood pressure reactivity. Implications for the understanding of allostasis and the dynamic nature of the relations between multiple physiological regulatory systems and adolescents' developing psychopathology are discussed.

Epidemiology of drinking, alcohol use disorders, and related problems in US ethnic minority groups.  

PubMed

This chapter reviews selected epidemiologic studies on drinking and associated problems among US ethnic minorities. Ethnic minorities and the White majority group exhibit important differences in alcohol use and related problems, including alcohol use disorders. Studies show a higher rate of binge drinking, drinking above guidelines, alcohol abuse, and dependence for major ethnic and racial groups, notably, Blacks, Hispanics, and American Indians/Alaskan Natives. Other problems with a higher prevalence in certain minority groups are, for example, cancer (Blacks), cirrhosis (Hispanics), fetal alcohol syndrome (Blacks and American Indians/Alaskan Natives), drinking and driving (Hispanics, American Indians/Alaskan Natives). There are also considerable differences in rates of drinking and problems within certain ethnic groups such as Hispanics, Asian Americans, and American Indians/Alaskan Natives. For instance, among Hispanics, Puerto Ricans and Mexican Americans drink more and have higher rates of disorders such as alcohol abuse and dependence than Cuban Americans. Disparities also affect the trajectory of heavy drinking and the course of alcohol dependence among minorities. Theoretic accounts of these disparities generally attribute them to the historic experience of discrimination and to minority socioeconomic disadvantages at individual and environmental levels.

Drug related problems in type 2 diabetes patients with hypertension: a cross-sectional retrospective study  

PubMed Central

Background Type 2 diabetes (T2DM) patients with hypertension are at increased risk for experiencing drug-related problems (DRPs) since they often receive multiple medications and have multiple comorbidities. To date, there is a lack of studies conducted in T2DM patients with hypertension. This study aims to analyze the DRPs and identify factors affecting the DRPs in this patient population. Method This retrospective study involved T2DM patients with hypertension and was conducted at a tertiary hospital in Malaysia from January 2009 to December 2011. The assessment of DRPs was based on the Pharmaceutical Network Care Europe (PCNE) tool version 5.01. Results Two hundred patients with a total of 387 DRPs were identified. Among these patients, 90.5% had at least one DRP, averaging 1.9?±?1.2 problems per patient. The most common DRPs encountered were insufficient awareness of health and diseases (26%), drug choice problems (23%), dosing problems (16%) and drug interactions (16%). The most implicated drugs were aspirin, clopidogrel, simvastatin, amlodipine and metformin. The six domains of DRPs found to have statistically significant associations were renal impairment, polypharmacy, cardiovascular disease, elderly status, and duration of hospital stay. Conclusions Early identification of the types and patterns of DRPs and the factors associated to them may enhance the prevention and management of DRPs in T2DM patients with hypertension.

The Two Extended Bodies Problem in General Relativity within the post-Newtonian Approximation  

E-print Network

The dynamics of extended bodies is a fundamental problem in any gravitational theory. In the case of General Relativity, this problem is under study since the theory was published. Several methods have been developed and different approaches are avalaible in the literature to interpret the relativistic contributions in the motion under gravity influence. The main goal in this thesis is to study a general method to face the equation of motion for extended bodies in General Relativity. We started with a proposal in the Newtonian theory, which consists in a multipolar expansion for the gravitational potentials as a function of the mass density moments and other physical variables as the stress tensor. The methodology give us the equation of motion for an isolated and self-gravitating system of extended bodies in Newtonian mechanics. A geometrical approach to get the equation of motion is also used for the Newtonian problems, it allows us to extend the methodology to General Relativity. In General Relativity, some new concepts are necessary: world tube, world line, generalized ideas of momentum, angular momentum, torque and center of mass are introduced in a general context. General expressions for the equation of motion in the case of extended bodies are written without any restriction. In order to gain some physical understanding, we compute the Papapetrous's equation of motion for a test extended body in a static and isotropic metric. Finally, we study a system of two extended bodies in the post-Newtonian approximation. We define the mass multipole moments and momentum from the gravitational potentials (metric functions) to the first post-Newtonian order. We follow the Landau-Liftshitz formalism to find out the equation of motion for the moments and applying the standard coordinate transformation for this theory, we write the traslational equation of motion.

Developmental trajectories of chinese children's relational and physical aggression: associations with social-psychological adjustment problems.  

PubMed

The purpose of this short-term longitudinal study was to examine Chinese children's trajectories of physical and relational aggression and their association with social-psychological adjustment problems (i.e., depressive symptoms and delinquency) and gender. Fourth and fifth grade children in Taiwan (n?=?739, age 9-11) were followed across 1 year. Results of Linear Mixed Models demonstrated that, on average, relational aggression increased in a linear fashion for fifth grade children and girls and physical aggression remained stable for boys and increased linearly for fifth grade girls. Further, increases in relational aggression were associated with time-dependent increases in depressive symptoms, and the effect size of this association seemed to be stronger than that of physical aggression. Findings are discussed in the context of Chinese culture. PMID:22477278

Parent and Self-Report Health-Related Quality of Life Measures in Young Patients With Tourette Syndrome  

PubMed Central

Tourette syndrome is a neurodevelopmental disorder characterized by tics and comorbid behavioral problems. This study compared child- and parent-reported quality of life and everyday functioning. We assessed 75 children with Tourette syndrome, of which 42 (56%) had comorbid conditions (obsessive-compulsive disorder = 25; attention-deficit hyperactivity disorder = 6; both comorbidities = 4). All patients completed psychometric instruments, including the Gilles de la Tourette Syndrome–Quality of Life Scale for Children and Adolescents (child report) and the Child Tourette’s Syndrome Impairment Scale (parent report). Data were compared for patients with pure Tourette syndrome, Tourette syndrome + obsessive-compulsive disorder, Tourette syndrome + attention-deficit hyperactivity disorder, and Tourette syndrome + both comorbidities. There were no group differences in quality of life. However, there were differences for total, school, and home activities impairment scores. Children and parents may not share similar views about the impact of Tourette syndrome on functioning. The measurement of health-related quality of life in Tourette syndrome is more complex in children than adults. PMID:22952315

Home hemodialysis and conventional in-center hemodialysis in Japan: A comparison of health-related quality of life.  

PubMed

Health-related quality of life (HRQOL) is an important measure of how disease affects patients' daily life. Conventional in-center hemodialysis (CHD) patients have been found to have decreased HRQOL. Recent study reported that at-home hemodialysis (HHD) improved the long-term HRQOL compared with CHD; however, there have been no data from Japanese HHD patients. A sample of 80 Japanese hemodialysis patients (46 HHD and 34 CHD) was matched for age, sex, and cause of end-stage renal disease. Patient HRQOL was measured using two health surveys: Medical Outcomes Study 36 Item Short Form Health Survey-Version 2 and Kidney Disease Quality of Life-Short Form. HHD patients reported better scores on seven out of eight domains (all domains except general heath) of the Medical Outcomes Study 36 Item Short Form Health Survey-Version 2, as well as better Kidney Disease Quality of Life-Short Form scores with respect to symptoms and problems, effect of kidney disease, and work status. No significant differences were observed for burden of kidney disease, cognitive function, quality of social interaction, sexual function, or sleep. More than 65% of HHD patients stated that they were not bothered at all by limitations on food and water intake. Japanese HHD patients demonstrate significantly higher HRQOL scores. However, while their HRQOL and employment rate were high and they were able to enjoy fewer dietary restrictions, kidney disease remained a great burden. PMID:25330829

Using ecotechnology to address water quality and wetland habitat loss problems in the Mississippi basin: a hierarchical approach.  

PubMed

Human activities are affecting the environment at continental and global scales. An example of this is the Mississippi basin where there has been a large scale loss of wetlands and water quality deterioration over the past century. Wetland and riparian ecosystems have been isolated from rivers and streams. Wetland loss is due both to drainage and reclamation, mainly for agriculture, and to isolation from the river by levees, as in the Mississippi delta. There has been a decline in water quality due to increasing use of fertilizers, enhanced drainage and the loss of wetlands for cleaning water. Water quality has deteriorated throughout the basin and high nitrogen in the Mississippi river is causing a large area of hypoxia in the Gulf of Mexico adjacent to the Mississippi delta. Since the causes of these problems are distributed over the basin, the solution also needs to be distributed over the basin. Ecotechnology and ecological engineering offer the only ecologically sound and cost-effective method of solving these problems. Wetlands to promote nitrogen removal, mainly through denitrification but also through burial and plant uptake, offer a sound ecotechnological solution. At the level of the Mississippi basin, changes in farming practices and use of wetlands for nitrogen assimilation can reduce nitrogen levels in the River. There are additional benefits of restoration of wetland and riverine ecosystems, flood control, reduction in public health threats, and enhanced wildlife and fisheries. At the local drainage basin level, the use of river diversions in the Mississippi delta can address both problems of coastal land loss and water quality deterioration. Nitrate levels in diverted river water are rapidly reduced as water flows through coastal watersheds. At the local level, wetlands are being used to treat municipal wastewater. This is a cost-effective method, which results in improved water quality, enhanced wetland productivity and increased accretion. The problems in the Mississippi basin serves as an example for other watersheds in the Gulf of Mexico. This is especially important in Mexico, where there is a strong need for economical solutions to ecological problems. The Usumacinta delta-Laguna de Terminos regional ecosystem is an example where ecotechnological approaches offer realistic solutions to environmental problems. PMID:14623048

Hierarchical Dobinski-type relations via substitution and the moment problem  

E-print Network

We consider the transformation properties of integer sequences arising from the normal ordering of exponentiated boson ([a,a*]=1) monomials of the form exp(x (a*)^r a), r=1,2,..., under the composition of their exponential generating functions (egf). They turn out to be of Sheffer-type. We demonstrate that two key properties of these sequences remain preserved under substitutional composition: (a)the property of being the solution of the Stieltjes moment problem; and (b) the representation of these sequences through infinite series (Dobinski-type relations). We present a number of examples of such composition satisfying properties (a) and (b). We obtain new Dobinski-type formulas and solve the associated moment problem for several hierarchically defined combinatorial families of sequences.

Averaging Problem in General Relativity, Macroscopic Gravity and Using Einstein's Equations in Cosmology  

E-print Network

The averaging problem in general relativity is briefly discussed. A new setting of the problem as that of macroscopic description of gravitation is proposed. A covariant space-time averaging procedure is described. The structure of the geometry of macroscopic space-time, which follows from averaging Cartan's structure equations, is described and the correlation tensors present in the theory are discussed. The macroscopic field equations (averaged Einstein's equations) derived in the framework of the approach are presented and their structure is analysed. The correspondence principle for macroscopic gravity is formulated and a definition of the stress-energy tensor for the macroscopic gravitational field is proposed. It is shown that the physical meaning of using Einstein's equations with a hydrodynamic stress-energy tensor in looking for cosmological models means neglecting all gravitational field correlations. The system of macroscopic gravity equations to be solved when the correlations are taken into consideration is given and described.

Design School-based group-randomized controlled design. Setting/participants 356 girls (mean age=15.8± 1.2 years) from six intervention and six control high schools. Over 75% of the girls were racial/ethnic minorities and 46% were overweight or obese. Data were collected in 2007–2009 and analyzed in 2009–2010. Intervention An all-girls physical education class, supplemented with nutrition and self-empowerment components, individual sessions using motivational interviewing, lunch meetings, and parent outreach. Main outcome measures Percent body fat, BMI, physical activity, sedentary activity, dietary intake, eating patterns, unhealthy weight control behaviors, and body/self-image. Results New Moves did not lead to significant changes in the girls’ percent body fat or BMI but improvements were seen for sedentary activity, eating patterns, unhealthy weight control behaviors, and body/self-image. For example, in comparison to control girls, at 9-month follow-up, intervention girls decreased their sedentary behaviors by approximately one 30-minute block a day (p=.050); girls increased their portion control behaviors (p=.014); the percentage of girls using unhealthy weight control behaviors decreased by 13.7% (p=.021), and improvements were seen in body image (p=.045) and self-worth (p=.031). Additionally, intervention girls reported more support by friends, teachers, and families for healthy eating and physical activity. Conclusions New Moves provides a model for addressing the broad spectrum of weight-related problems among adolescent girls. Further work is needed to enhance the effectiveness of interventions to improve weight status of youth. PMID:20965379

Associations between demographic, disease related, and treatment pathway related variables and health related quality of life in primary care patients with coronary heart disease  

PubMed Central

Background Coronory heart disease (CHD) is a common medical problem worldwide that demands shared care of general practitioners and cardiologists for concerned patients. In order to improve the cooperation between both medical specialists and to optimize evidence-based care, a treatment pathway for patients with CHD was developed and evaluated in a feasibility study according to the recommendation for the development and evaluation of complex interventions of the British Medical Research Council (MRC). In the context of this feasibility study the objective of the present research was to investigate the contributions of different disease related (e.g. prior myocardial infarction), pathway related (e.g. basic medication) and demographic variables on patients` perceived health related quality of life (HRQoL) as a relevant and widely used outcome measure in cardiac populations. Methods Data assessing demographic, disease and pathway related variables of CHD patients included in the study were collected in a quasi-experimental design with three study arms (pathway developers, users, control group) via case record forms and questionnaires at baseline and after 6 and 12 (intervention groups), and 9?months (control group), respectively after the initial implementation on GP level. Additionally, at the same measuring points the CHD patients participating in the study were interviewed by phone regarding their perceived HRQoL, measured with the EuroQol EQ-5D as an index-based health questionnaire. Due to the hierarchical structure of the data, we performed cross-sectional and longitudinal linear mixed models to investigate the impact of disease related, pathway related and demographic variables on patients` perceived HRQoL. Results Of 334 initially recruited patients with CHD, a total of 290 were included in our analysis. This was an average 13.2% dropout rate from baseline assessment to the 12-month follow-up. At all assessment points, patients` HRQoL was associated with a variety of sociodemographic variables (e.g. gender, employment, education) in each study group, but there was no association with pathway related variables. In both cross-sectional and longitudinal analyses highest HRQoL values in patients were reported in the physician group that had developed the pathway. In the longitudinal analyses there were no significant changes in the reported HRQoL values of the three groups over time. Conclusions The found associations between sociodemographic variables and the perceived HRQoL of patients with CHD are in line with other research. As there are no associations of HRQoL with pathway related variables like the basic medication, possible weaknesses in the study design or the choice of outcome have to be considered before planning and conducting an evaluation study according to the MRC recommendations. Additionally, as patients in the developer group reported the highest HRQoL values over time, a higher commitment of the GPs in the developer group can be assumed and should be considered in further research.

Computer Use and Vision-Related Problems Among University Students In Ajman, United Arab Emirate  

PubMed Central

Background: The extensive use of computers as medium of teaching and learning in universities necessitates introspection into the extent of computer related health disorders among student population. Aim: This study was undertaken to assess the pattern of computer usage and related visual problems, among University students in Ajman, United Arab Emirates. Materials and Methods: A total of 500 Students studying in Gulf Medical University, Ajman and Ajman University of Science and Technology were recruited into this study. Demographic characteristics, pattern of usage of computers and associated visual symptoms were recorded in a validated self-administered questionnaire. Chi-square test was used to determine the significance of the observed differences between the variables. The level of statistical significance was at P < 0.05. The crude odds ratio (OR) was determined using simple binary logistic regression and adjusted OR was calculated using the multiple logistic regression. Results: The mean age of participants was 20.4 (3.2) years. The analysis of racial data reveals that 50% (236/471) students were from Middle East, 32% (151/471) from other parts of Asia, 11% (52/471) from Africa, 4% (19/471) from America and 3% (14/471) from Europe. The most common visual problems reported among computer users were headache - 53.3% (251/471), burning sensation in the eyes - 54.8% (258/471) and tired eyes - 48% (226/471). Female students were found to be at a higher risk. Nearly 72% of students reported frequent interruption of computer work. Headache caused interruption of work in 43.85% (110/168) of the students while tired eyes caused interruption of work in 43.5% (98/168) of the students. When the screen was viewed at distance more than 50 cm, the prevalence of headaches decreased by 38% (50-100 cm – OR: 0.62, 95% of the confidence interval [CI]: 0.42-0.92). Prevalence of tired eyes increased by 89% when screen filters were not used (OR: 1.894, 95% CI: 1.065-3.368). Conclusion: High prevalence of vision related problems was noted among university students. Sustained periods of close screen work without screen filters were found to be associated with occurrence of the symptoms and increased interruptions of work of the students. There is a need to increase the ergonomic awareness among students and corrective measures need to be implemented to reduce the impact of computer related vision problems. PMID:24761249

The n-Body Problem in Spaces of Constant Curvature. Part I: Relative Equilibria  

NASA Astrophysics Data System (ADS)

We extend the Newtonian n-body problem of celestial mechanics to spaces of curvature ?=constant and provide a unified framework for studying the motion. In the 2-dimensional case, we prove the existence of several classes of relative equilibria, including the Lagrangian and Eulerian solutions for any ??0 and the hyperbolic rotations for ?<0. These results lead to a new way of understanding the geometry of the physical space. In the end we prove Saari's conjecture when the bodies are on a geodesic that rotates elliptically or hyperbolically.

[Preventing work-related health problems: the work of the ergonomist].  

PubMed

Preventing work-related health problems is an important aspect when considering clinical symptoms. Analysing a person's professional activity is a complex task. The ergonomist intervenes to understand the details of the organisational, environmental and cognitive structures that influence health. The case of a pre-school educator with back pain is presented here as an example of how such a situation is studied and concrete solutions instated. Health preservation strategies, facilitating factors and barriers were identified, which led to a reduction in straining, improved organisation of tasks and achievement of educational goals.
