    Efforts to relate shallow ground-water quality to the land use near a well lead to several statistical difficulties. These include potential uncertainty in land-use categorical data due to misclassification, data closure, distributional skewing, and spatial autocorrelation. Methods of addressing these problems are, respectively, the establishment of limits on minimum buffer radius, the estimation of contrasts, rank-based tests of association, and subsampling to prevent buffer overlap. Relations between the presence of purgeable organic compounds in ground water and land use are used to illustrate these problems and methods.

    1991-06-01

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

    1975-01-01

    A study to determine the present enrichment status of Liopez Reservoir in San Luis Obispo county, California, and to evaluate copper sulfate algal treatment found that stratification in the reservoir regulates nutrient release and that algal control has been ineffective. Nuisance algal blooms, particularly from March to June, have been a problem in the warm multipurpose reservoir since it was initially filled following intense storms in 1968-69. The cyanophyte Anabaena unispora has been dominant; cospecies are the diatoms Stephanodiscus astraea and Cyclotella operculata, and the chlorophytes Pediastrum deplex and Sphaerocystis schroeteri. During an A. unispora bloom in May 1972 the total lake surface cell count was nearly 100,000 cells/ml. Thermal stratification from late spring through autumn results in oxygen deficiency in the hypolimnion and metalimnion caused by bacterial oxidation of organic detritus. The anaerobic conditions favor chemical reduction of organic matter, which constitute 10-14% of the sediment. As algae die, sink to the bottom, and decompose, nutrients are released to the hypolimnion , and with the autumn overturn are spread to the epilimnion. Algal blooms not only hamper recreation, but through depletion of dissolved oxygen in the epilimnion may have caused periodic fishkills. Copper sulfate mixed with sodium citrate and applied at 1.10-1.73 lbs/acre has not significantly reduced algal growth; a method for determining correct dosage is presented. (Lynch-Wisconsin)

    2013-01-01

    Children with sickle cell disease (SCD) are at risk for poor health-related quality of life (HRQOL). The current analysis sought to explore parent problem-solving abilities/skills as a moderator between SCD complications and HRQOL to evaluate applicability to pediatric SCD. At baseline, 83 children ages 6–12 years and their primary caregiver completed measures of the child HRQOL. Primary caregivers also completed a measure of social problem-solving. A SCD complications score was computed from medical record review. Parent problem-solving abilities significantly moderated the association of SCD complications with child self-report psychosocial HRQOL (p = .006). SCD complications had a direct effect on parent proxy physical and psychosocial child HRQOL. Enhancing parent problem-solving abilities may be one approach to improve HRQOL for children with high SCD complications; however, modification of parent perceptions of HRQOL may require direct intervention to improve knowledge and skills involved in disease management.

    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.

    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

    Reinforcement-based interventions are highly efficacious in the treatment of substance use disorders, and their benefits can extend to other areas of functioning as well. In particular, reinforcing participation in job-related activities may be useful for improving employment outcomes, which in turn may enhance quality of life and decrease substance use. These secondary analyses compared substance abusing patients randomized to reinforcement interventions (N = 185) who selected and completed two or more job-related activities during treatment versus those who did not. Patients who completed two or more job-related activities during treatment had significantly greater reductions in employment-related problems and improvements in quality of life than those who completed only one or no job-related activities, even after controlling for baseline differences that may impact employment outcomes. Further, patients who completed employment activities remained in treatment significantly longer and achieved greater durations of abstinence than those who did not. These data suggest that reinforcing job-attainment activities may have broad beneficial effects. Reinforcement interventions should be considered for enhancing employment skills training acquisition more generally. PMID:23586451

    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.

    The correlates between public and private self-consciousness and internalizing difficulties were examined during early adolescence. Friendship quality was assessed as a possible moderator of the relation between self-consciousness and maladjustment. One hundred and thirty-seven young adolescents (N = 87 girls; M age = 13.98 years) reported on their self-consciousness, internalizing problems, and the quality of their best friendship. Results indicated stronger associations between private self-consciousness and internalizing correlates than between public self-consciousness and internalizing problems, suggesting that private self-consciousness may be a stronger risk factor during adolescence. Contrary to expectations, evidence revealed that positive friendship quality may exacerbate some difficulties associated with self-consciousness. Results pertaining to friendship quality add to the growing literature on the ways in which friendships can contribute to adjustment difficulties. PMID:19998530

    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.

    Dominance relations commonly are used to prune unnecessary nodes in search graphs, but they are problem-dependent and cannot be derived by a general procedure. 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.

    2011-01-01

    This report summarizes the analyses and results produced by a five-member investigative team of Government, university, and industry experts, established by NASA HQ. The team examined data quality problems associated with high performance liquid chromatography (HPLC) analyses of pigment concentrations in seawater samples produced by the San Diego State University (SDSU) Center for Hydro-Optics and Remote Sensing (CHORS). This report shows CHORS did not validate the methods used before placing them into service to analyze field samples for NASA principal investigators (PIs), even though the HPLC literature contained easily accessible method validation procedures, and the importance of implementing them, more than a decade ago. In addition, there were so many sources of significant variance in the CHORS methodologies, that the HPLC system rarely operated within performance criteria capable of producing the requisite data quality. It is the recommendation of the investigative team to a) not correct the data, b) make all the data that was temporarily sequestered available for scientific use, and c) label the affected data with an appropriate warning, e.g., "These data are not validated and should not be used as the sole basis for a scientific result, conclusion, or hypothesis--independent corroborating evidence is required."

    1995-01-01

    This article presents the results of a transboundary water quality monitoring program at the two Nogales area in the Arizona-Sonora border region. The program was carried out jointly in 1990 by U.S. and Mexican institutions. The results show pollution problems due to deficiencies in Nogales, Sonora municipal sewerage system, causing not only sewage spills in several parts of the city but also creating occasional transboundary problems. The results also showed potential illegal dumping of industrial hazardous waste (VOCs) into Nogales' municipal sewerage system. All of the organic compounds found in the sewage samples are solvents frequently used by the border industry. Occasional brakes of pipes spill the pollutants into the Nogales Wash, a water stream that runs parallel to Nogales' main sewerage line. Samples of the municipal water system showed no traces of pollutants. However, two rounds of samples detected concentrations of VOCs in wells used to supply water by trucks to low income neighborhoods in Nogales, Sonora. Ironically, the pollution detected in these wells has a greater impact in low income groups of the city that pay three to four times more per liter of water they consume, than the rest of the inhabitants with clean water from the municipal system.

    1989-01-01

    Issues and problems related to the needs for quantity and quality in health care have been presented. The need for quantity has been quite successfully addressed in the last 20 years. Better quality of health care is very much in the minds of policy makers, providers and the informed public. Quality assessment and assurance as a programmed and on-going process in individual hospitals is systematically promoted and developed. An accreditation system for hospitals is planned for the future. This paper has not been able to contribute anything of value to the current practice of quality assurance. The industrialized world has passed the stages Indonesia is now going through. To some Australian colleagues, this presentation perhaps has revealed that one of their closest neighbours is struggling hard to improve the quality of life of its people, despite the tremendous problems and constraints with which it is confronted. Australia has always provided a helping hand in this struggle. PMID:2486044

    Although a variety of successful no-reference (blind) picture quality analyzers have been proposed, progress on the blind video quality analysis problem has been slow. We break down the problem of perceptual blind video quality assessment (VQA) into components, which we address individually, before proposing a holistic solution. The idea is to tackle the challenges that comprise the blind VQA problem individually in order to gain a better understanding of it.

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

    1985-01-01

    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 percent. Recent balloon failures, coupled with an increased ocurrence 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 passsed 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.

    2011-01-01

    Despite its relatively recent emergence over the past few decades, oral health-related quality of life (OHRQoL) has important implications for the clinical practice of dentistry and dental research. OHRQoL is a multidimensional construct that includes a subjective evaluation of the individual’s oral health, functional well-being, emotional well-being, expectations and satisfaction with care, and sense of self. It has wide-reaching applications in survey and clinical research. OHRQoL is an integral part of general health and well-being. In fact, it is recognized by the World Health Organization (WHO) as an important segment of the Global Oral Health Program (2003). This paper identifies the what, why, and how of OHRQoL and presents an oral health theoretical model. The relevance of OHRQoL for dental practitioners and patients in community-based dental practices is presented. Implications for health policy and related oral health disparities are also discussed. A supplemental Appendix contains a Medline and ProQuest literature search regarding OHRQoL research from 1990-2010 by discipline and research design (e.g., descriptive, longitudinal, clinical trial, etc.). The search identified 300 articles with a notable surge in OHRQoL research in pediatrics and orthodontics in recent years. PMID:21422477

  18. A team quality improvement sequence for complex problems

    PubMed Central

    Ovretveit, J.

    1999-01-01

    To solve complex quality problems teams need to follow a systematic sequence of inquiry and action. In this article a practical description of a team quality improvement sequence (TQIS) is given based on the experience of the more successful teams in the Norwegian total quality management experiment. There are nine phases in the sequence and teams have the flexibility to choose the best quality methods for completing each phase. The strengths of the framework are in ensuring that personnel time is used cost effectively and that changes are made which result in measurable improvement. One limitation is that the framework has not been as widely tested as FOCUS-PDCA (find, organise, clarify, understand, select - plan, do, check, act) and other frameworks to which the TQIS framework is compared. It is proposed that if team projects are to be the main vehicle for quality improvement, then their work must be made more cost effective. The article aims to stimulate research into the conditions necessary for different quality teams to be successful in health care, and draws on the research to propose a "risk of team failure index" to improve the management of such teams.

    Although sociodemographic factors are one aspect of understanding the effects of neighborhood environments on health, equating neighborhood quality with socioeconomic status ignores the important role of physical neighborhood attributes. Prior work on neighborhood environments and health has relied primarily on level of socioeconomic disadvantage as the indicator of neighborhood quality without attention to physical neighborhood quality. A small but increasing number of studies have assessed neighborhood physical characteristics. Findings generally indicate that there is an association between living in deprived neighborhoods and poor health outcomes, but rigorous evidence linking specific physical neighborhood attributes to particular health outcomes is lacking. This paper discusses the methodological challenges and limitations of measuring physical neighborhood environments relevant to health and concludes with proposed directions for future work.

  9. Infant-mother attachment classification: risk and protection in relation to changing maternal caregiving quality.

    PubMed

    2006-01-01

    The relations between early infant-mother attachment and children's social competence and behavior problems during the preschool and early school-age period were examined in more than 1,000 children under conditions of decreasing, stable, and increasing maternal parenting quality. Infants' Strange Situation attachment classifications predicted mothers' reports of children's social competence and teachers' reports of externalizing and internalizing behaviors from preschool age through 1st grade. These relations appeared to be mediated by parenting quality; main effects of attachment classification disappeared when effects of parenting quality were controlled. Interactions were also observed. For example, when parenting quality improved over time, teachers rated children with insecure infant-mother attachments lower on externalizing behaviors; when parenting quality decreased, teachers rated insecure children higher on externalizing behaviors. In contrast, children classified as securely attached in infancy did not appear to be affected by declining or improving parenting quality. PMID:16420117

    2015-04-01

    The cause of the anomalous head posture (AHP) has been mainly assigned to ocular, orthopedic, and neurologic causes. The AHP can take the form of head tilt, face turn, chin up, chin down, or combined, depending on the specific etiology. However, there are many variations, and the type of the head posture cannot reliably predict the underlying cause. Ocular AHP is usually an attempt to improve visual acuity or binocularity. Since the etiology is not always obvious, we stress that these patients must be carefully evaluated by ophthalmologists. Our effort here is to offer the neurologist a thorough insight in the specific head posture pattern primarily related to visual disorders. PMID:24719022

    The influence of early relational experience on later social understanding has evoked rich theoretical discussion but relatively little empirical inquiry. Enlisting data from the NICHD Study of Early Child Care and Youth Development, measures of the security of attachment in infancy, toddlerhood, and early childhood, together with measures of parenting quality (maternal sensitivity and depressive symptoms) gathered longitudinally throughout infancy and early childhood, were used to predict differences in children's thoughts and feelings about peers (i.e., social problem solving, negative attributional biases, aggressive solutions to ambiguous social situations, and self-reported loneliness) when children were 54 months and in first grade. Relational experiences, especially before 36 months, were significantly predictive of later peer-related representations. Attachment security at 24 and 36 months was associated with enhanced social problem-solving skills and less loneliness, but security of attachment at 15 months was nonpredictive. Early maternal sensitivity was positively associated with later social problem-solving and negatively with aggressive responses, and early maternal depressive symptoms were positively associated with children's negative attributions. Concurrent parenting quality was also associated with children's thoughts and feelings about peers, but less consistently. These findings shed new light on how early relational experiences may contribute to social information processing with peers at the end of the preschool years, and that the timing of relational influences may be crucial.

    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

    The detection and correction of dietary errors plays an important role in avian medicine. Examples of diseases caused in part by a deficiency or abundance of a nutrient include hypovitaminosis A in birds of the parrot (Psittacidae) family, hypocalcemia in the African grey parrot, goitre in budgerigars, and iron storage diseases in the minah and toucan. Hypovitaminosis A can lead to metaplasia of mucous membranes, which in turn can lead to chronic rhinitis and respiratory fungal infections. Vitamin A deficiency is caused by feeding a seed based diet. Seed mixtures are often deficient in calcium, and nutritional secondary hyperparathyroidism can develop if an additional source of calcium, in the form of ground shells, is not provided. Tetanic symptoms as a result of hypocalcemia are only seen in the African grey parrot and the timneh parrot. Over supplementation of vitamin D gives rise to poisoning with polyuria and polydipsia as common initial symptoms. The exact cause of iron storage diseases in toucans and minahs is not known. A diet low in iron and vitamin C is advised as therapy. Goitre can develop in budgerigars as a result of iodine-deficient drinking water and provision of a seed mixture based on millet. An unbalanced or multideficient diet can give rise to reproductive disorders, abnormal feathers, or infections as a result of diminished resistance. It is usually not possible to relate the cause of these diseases in a simple way to the composition of the diet. Obesity, which occurs in the galah, Amazon parrot, and budgerigars, can lead to fatty liver and lipoma. A gradual reduction in weight, by means of calorie restriction, is recommended. Commercially available nutritionally balanced bird food is often effective. PMID:9929897

    2013-10-01

    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.

    TRIZ is an initiative and SERVQUAL is a structured methodology for quality improvement. Using these tools, inventive problem solving can be applied for quality improvement, and the highest quality can be reached using creative quality improvement methodology. The present study seeks to determine the priority of quality aspects of services provided for patients in the hospital as well as how TRIZ can help in improving the quality of those services. This Study is an applied research which used a dynamic qualitative descriptive survey method during year 2011. Statistical population includes every patient who visited in one of the University Hospitals from March 2011. There existed a big gap between patients' expectations from what seemingly is seen (the design of the hospital) and timely provision of services with their perceptions. Also, quality aspects of services were prioritized as follows: keeping the appearance of hospital (the design), accountability, assurance, credibility and having empathy. Thus, the only thing which mattered most for all staff and managers of studied hospital was the appearance of hospital as well as its staff look. This can grasp a high percentage of patients' satisfaction. By referring to contradiction matrix, the most important principles of TRIZ model were related to tangible factors including principles No. 13 (discarding and recovering), 25 (self-service), 35 (parameter changes), and 2 (taking out). Furthermore, in addition to these four principles, principle No. 24 (intermediary) was repeated most among the others. By utilizing TRIZ, hospital problems can be examined with a more open view, Go beyond The conceptual framework of the organization and responded more quickly to patients ' needs. PMID:25560360

    2015-01-01

    This study examines the relationship between clinical quality of care and physician productivity in the public sector clinical setting. This longitudinal study takes place in Jefferson County, Alabama using data from six public sector clinics. Data representing 21 physicians across 13 consecutive quarters representing 44,765 person observations were analyzed. Four variables were selected to represent quality of care for this pediatric patient population; two of which pertained to antibiotic use and two pertained to asthma care. Findings from multivariate analyses examining each quality of care measure and controlling for other visit and practice characteristics indicate that three of the four quality measures were significantly related to productivity. Specifically, the percent of asthma patients with documented asthma severity classification was negatively related to physician productivity (ß = -.24, p = .04), although the magnitude of this relationship was small. The percent of asthma patients prescribed an inhaled corticosteroid who also had a severity classification was negatively related to physician productivity (ß = -.23, p = .03) and the percent of patients prescribed oral antibiotics was marginally negatively related to physician productivity (ß = -.09, p = .09). In general, findings suggest that a relationship exists between quality of healthcare and physician productivity. Future research should continue to examine this relationship across other disciplines and healthcare settings. PMID:24033482

    2009-01-01

    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

  17. Weighted least squares in calibration: the problem with using "quality coefficients" to select weighting formulas.

    PubMed

    Tellinghuisen, Joel

    2008-09-01

    The quality coefficient (Q) has frequently been used to select weighting formulae in calibration, and especially so in bioanalytical work, where there has been increasing awareness of the importance of data heteroscedasticity in recent years. However, this quantity is statistically flawed and should not be used for this purpose. The quality coefficient is computed from the differences between the apparent and true concentrations of the calibration samples as obtained from the least-squares calibration fit. Q is defined as the sum of either the squares or the absolute values of these differences, taken directly or as percentage (relative) deviations. It is calculated for several different trial weighting formulae, and the lowest Q value is then deemed to identify the best weighting choice. However, these Qs are predisposed to favor data consistent with their definitions-homoscedastic data for tests employing absolute differences, and data having proportional error (constant coefficient of variance) for tests using relative differences--because the Q in each case closely resembles the quantity actually minimized by the least-squares fit of the calibration data. The problem is examined and illustrated through Monte Carlo computations on data having either constant or proportional uncertainty and subjected to both tests. A modified Q based on the results of both the absolute and relative tests is much more reliable than either test alone but is still not recommended as a solution to the weighting problem, as other, statistically sound approaches are available and readily used.

    Although reporting vision-related quality of life (VRQoL) outcomes has become increasingly common in adult glaucoma studies, little is known about the influence of disease severity, medication burden, and surgical experience on the quality of life of children with glaucoma. We tested the feasibility of administering a self-reported VRQoL instrument and describe the VRQoL in children with glaucoma. Better VRQoL was correlated with higher visual acuity in the better-seeing eye but not the number of surgeries the child had undergone or the number of prescribed eyedrops. PMID:24568998

  12. eEurope 2002: Quality Criteria for Health related Websites

    PubMed Central

    2002-01-01

    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.

    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

  5. The quantification of fingerprint quality using a relative contrast index.

    2008-06-10

    Research into fingermark enhancement techniques has traditionally used visual comparisons and qualitative methods to assess their effectiveness based on the quality of the developed fingermark. However, with increasing research into the optimisation of these techniques the need for a quantitative evaluative method has arisen. Parameters for acceptable fingerprint quality are not well defined and generally encompass clear, sharp edges and high levels of contrast between the fingermark ridges and background material. Using these current parameters, a conclusive measurement of fingerprint quality and thus the effectiveness of development techniques cannot be achieved. This study presents a model through which an aspect of fingerprint quality can be objectively and impartially measured based on a relative contrast index, constructed through measuring the reflective intensity of the fingermark ridges against the background material. Using a fibre-optic spectrophotometer attached to a microscope with axial illumination, the intensity counts of the ridge detail and background material were measured and a logarithmic contrast index constructed. The microscope and spectrophotometer parameters were experimentally tested using a standard colour resolution chart with known reflective properties. The protocol was successfully applied to four sample groups: black inked fingerprints on white paper; latent fingermarks on white paper developed separately with ninhydrin and physical developer; and fingermarks in blood deposited on white tiles and enhanced with amido black. The contrast indices obtained quantitatively reflect the level of contrast and provide an indication of fingerprint quality through a numerical representation rather than previous qualitative methods. It has been suggested that the proposed method of fingerprint quantification may be viable for application in the forensic research arena as it allows the definitive measurement of contrast to aid the evaluation of fingermark detection and enhancement techniques.

    Chow, P.-L.

    1978-01-01

    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.

    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 which 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

    2005-03-01

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

    Although prominent models of alcohol use and abuse implicate stress as an important motivator of alcohol consumption, research has not consistently identified a relationship between stress and drinking outcomes. Presumably stress leads to heavier alcohol consumption and related problems primarily for individuals who lack other adaptive methods for coping effectively with stressful experiences. To test this hypothesis, we examined four adaptive coping approaches (active coping, planning, suppression of competing activities, and restraint), as predictors of alcohol use and related problems as well as moderators of relations between stress and drinking outcomes in an undergraduate population (N=225). Further, we examined coping motives for drinking as potential mediators of the effects of coping strategies as well as stress by coping strategy interactions. Analyses supported both restraint and suppression of competing activities as moderators of the influence of stress on alcohol use but not problems. The stress by restraint interaction was also evident in the prediction of coping motives, and coping motives were related to higher levels of both weekly drinking and alcohol-related problems. Finally, coping motives for drinking served to mediate the stress by restraint interaction on weekly drinking. Overall, these results suggest that efforts to suppress competing activities and restrain impulsive responses in the face of stress may reduce the risk for heavy drinking during the transition from high school to college.

    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

    Previous research suggests that both jealousy and relationship contingent self-esteem (RCSE) are related to alcohol use and alcohol-related problems. No work, however, has examined these two constructs together as they relate to motives for alcohol use and alcohol-related problems. The current study aims to build upon emerging literature examining different types of jealousy (i.e., emotional, cognitive, and behavioral), relationship quality (i.e., satisfaction, commitment, closeness), RCSE, and alcohol use. More specifically, the current study aimed to examine the associations between RCSE and drinking to cope and RCSE and alcohol-related problems, in the context of the different types of jealousy. Moreover, the current study aimed to assess whether the associations between RCSE, jealousy, and drinking outcomes vary as a function of relationship quality. Two hundred and seventy seven individuals (87% female) at a large southern university participated in the study. They completed measures of RCSE, relationship satisfaction, commitment, closeness, and jealousy as well as alcohol-related outcomes. Using PROCESS, moderated mediational analyses were used to evaluate different types of jealousy as mediators of the association between RCSE and drinking to cope/alcohol-related problems. Further, we aimed to examine whether relationship quality moderated the association between RCSE and jealousy in predicting alcohol-related variables. Results indicated that cognitive jealousy mediated the association between both RCSE and drinking to cope and RCSE and alcohol-related problems. Further, relationship satisfaction, commitment, and closeness were all found to moderate the association between RSCE and cognitive jealousy such that at lower, but not higher levels of satisfaction, commitment, and closeness, cognitive jealousy mediated the association between RCSE and drinking to cope and RCSE and alcohol-related problems.

    An analysis is presented of data on students' problem-solving performance on similar problems posed in diverse representations. Five years of classroom data on 400 students collected in a second-semester algebra-based general physics course are presented. Two very similar Newton's third-law questions, one posed in a verbal representation and one in a diagrammatic representation using vector diagrams, were given to students at the beginning of the course. The proportion of correct responses on the verbal question was consistently higher than on the diagrammatic question, and the pattern of incorrect responses on the two questions also differed consistently. Two additional four-question quizzes were given to students during the semester; each quiz had four very similar questions posed in the four representations: verbal, diagrammatic, mathematical/symbolic, and graphical. In general, the error rates for the four representations were very similar, but there was substantial evidence that females had a slightly higher error rate on the graphical questions relative to the other representations, whereas the evidence for male students was more ambiguous. There also was evidence that females had higher error rates on circuit-diagram problems in comparison with males, although both males and females had received identical instruction .

    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.

  3. Origins and development of the Cauchy problem in general relativity

    Ringström, Hans

    2015-06-01

    The seminal work of Yvonne Choquet-Bruhat published in 1952 demonstrates that it is possible to formulate Einstein's equations as an initial value problem. The purpose of this article is to describe the background to and impact of this achievement, as well as the result itself. In some respects, the idea of viewing the field equations of general relativity as a system of evolution equations goes back to Einstein himself; in an argument justifying that gravitational waves propagate at the speed of light, Einstein used a special choice of coordinates to derive a system of wave equations for the linear perturbations on a Minkowski background. Over the following decades, Hilbert, de Donder, Lanczos, Darmois and many others worked to put Einstein's ideas on a more solid footing. In fact, the issue of local uniqueness (giving a rigorous justification for the statement that the speed of propagation of the gravitational field is bounded by that of light) was already settled in the 1930s by the work of Stellmacher. However, the first person to demonstrate both local existence and uniqueness in a setting in which the notion of finite speed of propagation makes sense was Yvonne Choquet-Bruhat. In this sense, her work lays the foundation for the formulation of Einstein's equations as an initial value problem. Following a description of the results of Choquet-Bruhat, we discuss the development of three research topics that have their origin in her work. The first one is local existence. One reason for addressing it is that it is at the heart of the original paper. Moreover, it is still an active and important research field, connected to the problem of characterizing the asymptotic behaviour of solutions that blow up in finite time. As a second topic, we turn to the questions of global uniqueness and strong cosmic censorship. These questions are of fundamental importance to anyone interested in justifying that the Cauchy problem makes sense globally. They are also closely related to the issue of singularities in general relativity. Finally, we discuss the topic of stability of solutions to Einstein's equations. This is not only an important and active area of research, it is also one that only became meaningful thanks to the work of Yvonne Choquet-Bruhat.

    Objective To evaluate the feasibility, reliability, validity, and responsiveness of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL) in the first 2 weeks after pediatric emergency department care of minor injury. Design Prospective cohort study. Setting Pediatric hospital emergency department. Participants Children and adolescents with minor injury (n = 334). Main Outcome Measures Child- and parent-reported clinical outcomes and PedsQL scale scores. Results The PedsQL had good to excellent internal consistency reliability (? range, 0.73–0.93). For each day that the clinical symptoms persisted, there were consistent decreases in mean health-related quality of life (HRQOL) scores (validity testing). There were significantly greater negative changes in mean HRQOL scores for fractures vs soft-tissue injuries and for lower vs upper extremity injuries. Clinical outcomes categorized as poor had large negative changes in HRQOL not seen in good outcome groups. Distribution-based indicators of change supported good responsiveness (effect sizes for the physical summary score, 0.01–2.44; group differences at follow-up exceeded estimates of the minimal importance difference). Conclusions The PedsQL is feasible, reliable, and demonstrates good construct and discriminant validity and responsiveness in measuring short-term outcome after minor injury care in the pediatric emergency department. Assessing short-term outcome from the patient perspective with HRQOL measures may greatly enhance our ability to evaluate the effectiveness of emergency department care. PMID:22213754

    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.

  12. A Solution to the Cosmological Problem of Relativity Theory

    NASA Astrophysics Data System (ADS)

    Janzen, Daryl

    After nearly a century of scientific investigation, the standard cosmological theory continues to have many unexplained problems, which invariably amount to one troubling statement: we know of no good reason for the Universe to appear just as it does, which is described extremely well by the flat ?CDM cosmological model. Therefore, the problem is not that the physical model is at all incompatible with observation, but that, as our empirical results have been increasingly constrained, it has also become increasingly obvious that the Universe does not meet our prior expectations; e.g., the evidence suggests that the Universe began from a singularity of the theory that is used to describe it, and with space expanding thereafter in cosmic time, even though relativity theory is thought to imply that no such objective foliation of the spacetime continuum should reasonably exist. Furthermore, the expanding Universe is well-described as being flat, isotropic, and homogeneous, even though its shape and expansion rate are everywhere supposed to be the products of local energy-content---and the necessary prior uniform distribution, of just the right amount of matter for all three of these conditions to be met, could not have been causally determined to begin with. And finally, the empirically constrained density parameters now indicate that all of the matter that we directly observe should make up only four percent of the total, so that the dominant forms of energy in the Universe should be dark energy in the form of a cosmological constant, ?, and cold dark matter (CDM). The most common ways of attacking these problems have been: to apply modifications to the basic physical model, e.g. as in the inflation and quintessence theories which strive to resolve the horizon, flatness, and cosmological constant problems; to use particle physics techniques in order to formulate the description of dark matter candidates that might fit with observations; and, in the case of the Big Bang singularity, to appeal to the need for a quantum theory of gravity. This thesis takes a very different approach to the problem, in hypothesising that, because our physical model really does appear to do a very good job of describing the observed cosmic expansion rate, and all the data indicate that our Universe might well expand precisely according to the flat ?CDM scale-factor, it may not be the model, but our basic expectations that need to be modified in order to derive a physical theory that stands in reasonable agreement with the empirical results; i.e., that it may actually be that we need to re-examine, and rationally modify our expectations of what should theoretically be, so that we might derive a theory to explain the empirical results of cosmology, which would be based solely on reasonably acceptable first principles. Therefore, a self-consistent theory is constructed here, upon re-consideration of the cosmological foundations of relativity theory, which eventually does afford an explanation of the cosmological problem, as it provides good reason to actually expect observations in the fundamental rest-frame to be described precisely by the flat ?CDM scale-factor which has been empirically constrained.

    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.

    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

    In 2002, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) issued a report entitled A Call to Action: Changing the Culture of Drinking at U.S. Colleges. Data on the magnitude of college drinking problems in 1998 to 1999 were reported. From 1999 to 2005, the proportion of college students aged 18–24 who drank five or more drinks on a single occasion in the past month increased from 41.7 percent to 45.2 percent. The proportion who drove under the influence of alcohol increased from 26.1 percent to 29.2 percent. Higher percentages of 21- to 24-year-olds engaged in those behaviors than 18- to 20-year-olds, and between 1999 and 2005 the percentage increased among 21- to 24-year-olds but not among those aged 18–20. From 1998 to 2005, unintentional alcohol-related injury deaths increased 3 percent (from 1,442 to 1,825) per 100,000 college students aged 18–24. Alcohol misuse by college students often harms other people through traffic crashes and sexual/other assaults. Research regarding ways to reduce college drinking problems has shown that individual-oriented interventions, particularly screening and brief motivational counseling interventions, social norms interventions, environmental policy changes such as the minimum legal drinking age of 21 and drinking-and-driving laws, and comprehensive college–community programs, can reduce college drinking and related morbidity and mortality. There is a growing need for colleges and surrounding communities to implement interventions shown through research to reduce alcohol misuse among college-aged people. PMID:23579935

    The family is the key support network for children with autism spectrum disorder (ASD), in many cases into adulthood. The Family Quality of Life (FQOL) construct encompasses family satisfaction with both internal and external dynamics, as well as support availability. Therefore, although these families face considerable risk in raising a child with a disability, the FQOL outcome is conceptualized as representative of a continuum of family adaptation. This study examined the role of child characteristics, including adaptive functioning and behaviour problems, in relation to FQOL. Eighty-four caregivers of children and adolescents (range?=?6-18 years) with ASD participated, completing questionnaires online and by telephone. Adaptive functioning, and specifically daily living skills, emerged as a significant predictor of FQOL satisfaction, after accounting for behavioural and demographic characteristics, including child age, gender, perceived disability severity, and behavioural problems, as well as family income. Furthermore, there were significant differences across each domain of FQOL when groups were separated by daily living skill functioning level ('low,' 'moderately low,' and 'adequate'). The results suggest that intervention strategies targeting daily living skills will likely have beneficial effects for both individual and family well-being, and may reduce family support demands.

    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.

    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.

    2013-01-01

    Background The quality of life (QOL) of caregivers of individuals with chronic spinal cord injuries may be affected by several factors. Moreover, this issue is yet to be documented fully in the literature. The purpose of this study was to evaluate the health related quality of life of spouses who act as primary caregivers of veterans with chronic spinal cord injuries in Iran. Methods The study consisted of 72 wives of 72 veterans who were categorized as spinal cord injured patients based on the American Spinal Injury Association (ASIA) classification. Health related quality of life was assessed by the Short Form (SF-36) Health Survey. Pearson's correlation was carried out to find any correlation between demographic variables with SF-36 dimensions. To find the effect of the factors like age, employment status, duration of care giving, education, presence or absence of knee osteoarthritis, and mechanical back pain on different domains of the SF-36 health survey, Multivariate analysis of variance (MANOVA) was used. Results The mean age of the participants was 44.7 years. According to the ASIA classification 88.9% and 11.1% of the veterans were paraplegic and tetraplegic respectively. Fifty percent of them had a complete injury (ASIA A) and 85% of the spouses were exclusive care givers. All of the SF-36 scores of the spouses were significantly lower than the normal population. Pearson's correlation demonstrated a negative significant correlation between both age and duration of caring with the PF domain. The number of children had a negative correlation with RE and VT. Conclusion The burden of caregiving can impact the QOL of caregivers and cause health problems. These problems can cause limitations for caregiver spouses and it can lead to a decrease in the quality of given care. PMID:23506336

    Background Women facing social and economic disadvantage in stressed communities of developing countries are at greater risk due to health problems. This paper investigates the relationships between structural, health and psychosocial predictors among women in mining and agricultural communities. This paper is a report of a study of the predictors of the health-related quality of life among Indian women in mining and agricultural communities. Methods A descriptive cross-sectional research design was used. The instruments used are SF-36 Health Survey and Coping Strategy Checklist. ANOVA, MANOVA and GLM were used in the analysis. The study was conducted between January-September 2008 with randomly selected women in a mining (145) and an agricultural community (133) in India. Results Women in the agricultural community had significantly increased Physical Health, Mental Health and SF36 scores compared with those in the mining community. Years of stay, education and employment were significant predictors among women in the agricultural community. 39% (33%) and 40% (26%) of the variance in Physical and Mental health respectively among women in agricultural and mining communities are predicted by the structural, health and psychosocial variables. Conclusion Perceived health status should be recognised as an important assessment of Physical and Mental Health among women in rural stressed communities. Cognitive, emotional and behavioural coping strategies are significant predictors of health related quality of life. Implications. Nurses should use the SF-36 as a diagnostic tool for assessing health related quality of life among women and discuss coping strategies, so that these can target women’s adaptive behaviour. This should be an essential part of the nursing process for facilitating adaptive process for improved health related quality of life. PMID:23336256

    Objective: To provide a rigorous and critical review of studies in which formal neuropsychological (NP) testing and measurement of health-related quality of life (HRQL) were conducted pre- and post-parathyroidectomy for primary hyperparathyroidism (PHPT). These data contribute to the discussion on the utility of surgical intervention for nonclassic PHPT. Summary Background Data: PHPT is a complex endocrinopathy involving calcium metabolism and a potent hormone made by the parathyroid glands. Approximately 1.5% of Americans age 65 years and older, representing more than 3.9 million people, have PHPT, and the prevalence in postmenopausal women is estimated at 3.4%. Current National Institutes of Health guidelines for curative, surgical intervention of PHPT exclude 80% of patients with hyperparathyroid disease who have subjective neurobehavioral and physical symptoms that affect the quality of their lives. Methods: An electronic search was conducted of prospective studies in which cognitive functioning was measured with formal NP tests and HRQL was measured with valid and reliable instruments before and following parathyroidectomy for PHPT. Results: In studies conducted pre- and post-parathyroidectomy for PHPT, 6 small studies of cognitive functioning report inconsistent findings; however, 7 well-designed studies of HRQL report improvement across multiple domains following surgery. Conclusions: Surgical treatment of PHPT is a viable option for patients with laboratory diagnosed, “nonclassic” PHPT. Formal NP testing and evaluation of HRQL are useful tools that may assist physicians in choosing whom to refer for parathyroidectomy. Further longitudinal study of NP functioning and HRQL in patients with laboratory diagnosed PHPT is warranted. PMID:16244536

    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.

    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

    A classical ray tracing problem, namely the celebrated Alhazen Mirror Problem, is reviewed. An alternative formulation of the law of reflection, leading, in the spherical mirror case, directly to Alhazen's equation is presented. The locus method of ray tracing is introduced and applied to Alhazen's problem. Finally, the technique is applied to some ray tracing problems, which often occur in practice, namely reflection by a circular cylinder and diffraction by a circular edge. Although these problems cannot in general be solved analytically, a technique is devised that may save considerable amounts of computer time in actual applications.

    2013-01-01

    Background Obesity impairs health related quality of life (HRQL) in adolescents, but most evidence in this area has mostly come from western societies. We wanted to test the hypothesis that obesity impairs HRQL in Kuwaiti adolescents, and to test for differences in HRQL assessed by self-report and parent-proxy report. Methods In 500 Kuwaiti 10–14 year olds HRQL was assessed using the Peds QLTM with both adolescent self-reports (n?=?500) and parent-proxy reports (n?=?374). Results Obesity was not significantly associated with HRQL in regression analysis. In a paired comparison of 98 pairs of obese adolescents vs. 98 healthy weight peers, impairment of HRQL reached significance only for physical score (95% CI?=??1.5, -9.4), not for psychosocial score or total score. In a paired comparison of parent-proxy vs. self-reports for the obese adolescents, total score (95% CI?=??4.9, -10.9), physical score (95% CI?=??3.2, -11.0), and psychosocial score (95% CI?=??4.2, -10.8) were all significantly lower in the parent reports. Conclusions Obesity is not associated with marked impairment of HRQL in adolescents in Kuwait, in contrast to studies in western societies. This may reflect cultural differences in attitudes towards obesity. PMID:23845118

    2012-01-01

    Background A systematic literature review was conducted to (a) identify the most frequently used health-related quality of life (HRQOL) models and (b) critique those models. Methods Online search engines were queried using pre-determined inclusion and exclusion criteria. We reviewed titles, abstracts, and then full-text articles for their relevance to this review. Then the most commonly used models were identified, reviewed in tables, and critiqued using published criteria. Results Of 1,602 titles identified, 100 articles from 21 countries met the inclusion criteria. The most frequently used HRQOL models were: Wilson and Cleary (16%), Ferrans and colleagues (4%), or World Health Organization (WHO) (5%). Ferrans and colleagues’ model was a revision of Wilson and Cleary’s model and appeared to have the greatest potential to guide future HRQOL research and practice. Conclusions Recommendations are for researchers to use one of the three common HRQOL models unless there are compelling and clearly delineated reasons for creating new models. Disease-specific models can be derived from one of the three commonly used HRQOL models. We recommend Ferrans and colleagues’ model because they added individual and environmental characteristics to the popular Wilson and Cleary model to better explain HRQOL. Using a common HRQOL model across studies will promote a coherent body of evidence that will more quickly advance the science in the area of HRQOL. PMID:23158687

    Purpose The purpose of this study was to investigate the effect of residential blind rehabilitation on patients’ vision targeted health-related quality of life (HRQOL) and general physical and mental function. Methods The National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ) plus appendix questions, the 12 item Short-Form Health Survey (SF-12), Hope Scale and Coopersmith self-esteem inventory were administered to 206 legally blind veterans prior to their entering a residential (in-patient) blind rehabilitation program and again to 185 and 176 of the original cohort at two and six months after completion of the rehabilitation program, respectively. Data on visual acuity, visual field extent, contrast sensitivity and scanning ability were also collected. The duration of the in-patient rehabilitation programs ranged from 11–109 days. Questionnaire scores were compared pre-rehabilitation and post-rehabilitation. Results Following rehabilitation there was a significant improvement in nine of eleven NEI VFQ subscales and in a composite score at both 2- and 6-month post-rehab intervals. Mental health (SF-12) and self esteem also improved significantly although physical health ratings declined over the course of the study (approximately 10 months). Conclusions Residential blind rehabilitation appears to improve patients’ self-reported vision-targeted HRQOL, self-esteem, and mental health aspects of generic HRQOL. PMID:18392688

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

    2011-01-01

    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.

    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.

    2014-01-01

    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

    2005-01-01

    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.

    2015-01-01

    Approximately 43% of children in the United States (32 million) are currently living with at least 1 of 20 common chronic childhood illnesses. The most common chronic childhood illnesses are asthma, cystic fibrosis, diabetes, obesity, malnutrition, developmental disabilities, cerebral palsy, consequences of low birthweight, and mental illness. For all chronically ill pediatric populations, the outcome of health-related quality of life (HRQOL) is particularly important because many of these children have not and will not be cured, and will continue to manage their chronic illness into adulthood. Advances in biomedical science and technology continue to improve efficacy of treatments and care for chronically ill children, adolescents, and their families, which highlight the importance measurement of HRQOL as a treatment and health status outcome. The construct of HRQOL is subjective, multidimensional, dynamic, and unique to each individual. It includes aspects of physical, psychological, social function, and goal attainment. Outcomes of HRQOL now include the financial implications for these children and their families, as well as financial and organizational consequences for healthcare planning and delivery of services.This article reviews the importance of HRQOL as a health outcome for chronically ill children. A historical overview and synthesis of the conceptualization and measurement of HRQOL for the chronically ill pediatric population is provided. Current research investigations that have measured health outcomes using individual scales tailored to children's specific symptoms health outcomes, such as PROMIS®-Patient Reported Outcomes Measurement Information System-are reviewed. The clinical applications of HRQOL outcomes research include facilitation of patient-healthcare provider communication, improved patient satisfaction, identification of hidden morbidities, a positive impact on clinical decision making, and improvement of patient outcomes over time.

    Shock waves are steep wave fronts that are fundamental in nature, especially in high-speed fluid flows. When a shock hits an obstacle, or a flying body meets a shock, shock reflection/diffraction phenomena occur. In this paper, we show how several longstanding shock reflection/diffraction problems can be formulated as free boundary problems, discuss some recent progress in developing mathematical ideas, approaches, and techniques for solving these problems, and present some further open problems in this direction. In particular, these shock problems include von Neumann's problem for shock reflection-diffraction by two-dimensional wedges with concave corner, Lighthill's problem for shock diffraction by two-dimensional wedges with convex corner, and Prandtl-Meyer's problem for supersonic flow impinging onto solid wedges, which are also fundamental in the mathematical theory of multidimensional conservation laws.

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

    OBJECTIVES To explore central challenges with translating self-reported measurement tools for functional status and health-related quality of life (HRQOL) into ambulatory quality indicators for older people with multiple chronic conditions (MCCs). DESIGN Review. SETTING Sources including the National Quality Measures Clearinghouse and National Quality Forum were reviewed for existing ambulatory quality indicators relevant to functional status, HRQOL, and people with MCCs. PARTICIPANTS Seven informants with expertise in indicators using functional status and HRQOL. MEASUREMENTS Informant interviews were conducted to explore knowledge about these types of indicators, particularly usability and feasibility. RESULTS Nine important existing indicators were identified in the review. For process, identified indicators addressed whether providers assessed functional status; outcome indicators addressed quality of life. In interviews, informants agreed that indicators using self-reported data were important in this population. Challenges identified included concerns about usability due to inability to discriminate quality of care adequately between organizations and feasibility concerns regarding high data collection burden, with a correspondingly low response rate. Validity was also a concern because evidence is mixed that healthcare interventions can improve HRQOL or functional status for this population. As a possible first step, a structural standard could be systematic collection of these measures in a specific setting. CONCLUSION Although functional status and HRQOL are important outcomes for older people with MCCs, few relevant ambulatory quality indicators exist, and there are concerns with usability, feasibility, and validity. Further research is needed on how best to incorporate these outcomes into quality indicators for people with MCCs. PMID:24320819

    The string editing problem for input strings x and y consists of transforming x into y by performing a series of weighted edit operations on x of overall minimum cost. An edit operation on x can be the deletion of a symbol from x, the insertion of a symbol in x or the substitution of a symbol x with another symbol. This problem has a well known O((absolute value of x)(absolute value of y)) time sequential solution (25). The efficient Program Requirements Analysis Methods (PRAM) parallel algorithms for the string editing problem are given. If m = ((absolute value of x),(absolute value of y)) and n = max((absolute value of x),(absolute value of y)), then the CREW bound is O (log m log n) time with O (mn/log m) processors. In all algorithms, space is O (mn).

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

    Perceptual quality assessment of digital images and videos are important for various image-processing applications. For assessing the image quality, researchers have often used the idea of visual masking (or distortion visibility) to design image-quality predictors specifically for the near-threshold distortions. However, it is still unknown that while assessing the quality of natural images, how the local distortion visibilities relate with the local quality scores. Furthermore, the summing mechanism of the local quality scores to predict the global quality scores is also crucial for better prediction of the perceptual image quality. In this paper, the local and global qualities of six images and six distortion levels were measured using subjective experiments. Gabor-noise target was used as distortion in the quality-assessment experiments to be consistent with our previous study [Alam, Vilankar, Field, and Chandler, Journal of Vision, 2014], in which the local root-mean-square contrast detection thresholds of detecting the Gabor-noise target were measured at each spatial location of the undistorted images. Comparison of the results of this quality-assessment experiment and the previous detection experiment shows that masking predicted the local quality scores more than 95% correctly above 15 dB threshold within 5% subject scores. Furthermore, it was found that an approximate squared summation of local-quality scores predicted the global quality scores suitably (Spearman rank-order correlation 0:97).

    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.

    2014-09-01

    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.

    Orbit correction - moving the orbit to a desired orbit, orbit stability - keeping the orbit on the desired orbit using feedback to filter out unwanted noise, and orbit analysis - to learn more about the model of the machine, are strongly interrelated. They are the three facets of the same problem. The better one knows the model of the machine, the better the predictions that can be made on the behavior of the machine (inverse modeling) and the more accurately one can control the machine. On the other hand, one of the tools to learn more about the machine (modeling) is to study and analyze the orbit response to {open_quotes}kicks.{close_quotes}

    For the last 15-20 years the study of interhemispheric relations made a big progress. This progress was facilitated by use of new methods in combination with midsagittal sections of comissural connections at different levels. An assumption is made that interhemispheric exchange of sensory information is of certain importance for the short-term memory and for compensatory mechanisms of the brain. The importance of hemispheric interaction for coordinated motor reactions and for subtle spatial orientation of animals is determined. Observation of patients with surgically dissected brain is a big contribution to further study of interhemispheric relations. PMID:366955

    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

    The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism (n = 30) and peers (n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves (p < .001) or their parents (p < .001), although disagreement (intra-class coefficient = -.075) between children and parental scores suggested variance in points of view. This study specifically investigated health-related quality of life in children with high-functioning autism as compared to a sample of peers, from the child's perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child's life that promote or hinder their sense of well-being.

    PubMed Central

    Rannala, B; Slatkin, M

    1998-01-01

    In this paper a theory is developed that provides the sampling distribution of alleles at a diallelic marker locus closely linked to a low-frequency allele that arose as a single mutant. The sampling distribution provides a basis for maximum-likelihood estimation of either the recombination rate, the mutation rate, or the age of the allele, provided that the two other parameters are known. This theory is applied to (1) the data of Hästbacka et al., to estimate the recombination rate between a locus associated with diastrophic dysplasia and a linked RFLP marker; (2) the data of Risch et al., to estimate the age of a presumptive allele causing idiopathic distortion dystonia in Ashkenazi jews; and (3) the data of Tishkoff et al., to estimate the date at which, at the CD4 locus, non-African lineages diverged from African lineages. We conclude that the extent of linkage disequilibrium can lead to relatively accurate estimates of recombination and mutation rates and that those estimates are not very sensitive to parameters, such as the population age, whose values are not known with certainty. In contrast, we also conclude that, in many cases, linkage disequilibrium may not lead to useful estimates of allele age, because of the relatively large degree of uncertainly in those estimates.

    This study examined the associations among thinking style (rational versus experiential), gambling related cognitions, and problem gambling severity. The participants were 70 female and 41 male regular gamblers who completed the Gambling Related Cognitions Scale (Raylu and Oei, Addiction 99:757-769, 2004), the Rational-Experiential Inventory (Pacini and Epstien, J Pers Soc Psychol 76(6):972-987, 1999), and the Problem Gambling Severity Index (Ferris and Wynne, The Canadian problem and gambling index: final report. Canadian Centre on Substance Abuse, Ottawa, 2001). Rational thinking was negatively related to problem gambling severity. Gambling related biases increased with problem gambling severity but the strength of those biases was dampened by rational thought. The patterns by which gambling related cognition mediated the association between thinking style and gambling severity suggest that therapeutic interventions may benefit from a consideration of a gambler's thinking style.

  12. Smoking and health-related quality of life in English general population: implications for economic evaluations

    PubMed Central

    2012-01-01

    Background Little is known as to how health-related quality of life (HRQoL) when measured by generic instruments such as EQ-5D differ across smokers, ex-smokers and never-smokers in the general population; whether the overall pattern of this difference remain consistent in each domain of HRQoL; and what implications this variation, if any, would have for economic evaluations of tobacco control interventions. Methods Using the 2006 round of Health Survey for England data (n = 13,241), this paper aims to examine the impact of smoking status on health-related quality of life in English population. Depending upon the nature of the EQ-5D data (i.e. tariff or domains), linear or logistic regression models were fitted to control for biology, clinical conditions, socio-economic background and lifestyle factors that an individual may have regardless of their smoking status. Age- and gender-specific predicted values according to smoking status are offered as the potential 'utility' values to be used in future economic evaluation models. Results The observed difference of 0.1100 in EQ-5D scores between never-smokers (0.8839) and heavy-smokers (0.7739) reduced to 0.0516 after adjusting for biological, clinical, lifestyle and socioeconomic conditions. Heavy-smokers, when compared with never-smokers, were significantly more likely to report some/severe problems in all five domains - mobility (67%), self-care (70%), usual activity (42%), pain/discomfort (46%) and anxiety/depression (86%) -. 'Utility' values by age and gender for each category of smoking are provided to be used in the future economic evaluations. Conclusion Smoking is significantly and negatively associated with health-related quality of life in English general population and the magnitude of this association is determined by the number of cigarettes smoked. The varying degree of this association, captured through instruments such as EQ-5D, may need to be fed into the design of future economic evaluations where the intervention being evaluated affects (e.g. tobacco control) or is affected (e.g. treatment for lung cancer) by individual's (or patients') smoking status.

    The Index of Nutritional Quality (INQ) is a method of quantitative and qualitative analysis of single foods, meals, and diets which has special significance in assessing clinical nutritional problems. The INQ is a ratio of the nutrient-to-calorie content of foods which may be calculated by computer and printed as bar graphs and tabular data. The number of nutrients and the nutrient standards used for analysis are flexible parameters which may be varied for each clinical situation. Illustrative examples include INQ analysis of simple foods, an institutional house diet, the diabetic Exchange list, and the diagnostic evaluation of the dietary intake of a hospitalized patient.

    Objectives?To examine disordered eating and associations with health-related quality of life (HRQOL) in rural overweight/obese (OW/OB) children.?Methods?Cross-sectional analyses were conducted with 272 rural OW/OB children aged 8–12 years (M = 10.36; SD = 1.39). Child anthropometrics, demographics, disordered eating attitudes, unhealthy weight control behaviors (UWCBs), and HRQOL were measured. Relationships between these variables were analyzed using bootstrapped multiple linear regressions.?Results?Clinically significant disordered eating attitudes were endorsed by 17% of the sample, and the majority endorsed UWCBs. Disordered eating attitudes and weight status were the most common predictors of HRQOL. Disordered eating attitudes and UWCBs were negatively related to emotional HRQOL but were unrelated to social, school, or physical HRQOL.?Conclusions?Disordered eating is a serious and relevant problem in OW/OB children living in rural areas and may be indicative of impairments in emotional functioning. Early intervention may reduce the risk for eating disorders and associated negative sequelae. PMID:24676798

    2015-01-01

    The theory of task-based assessment of image quality is reviewed in the context of imaging with ionizing radiation, and objective figures of merit (FOMs) for image quality are summarized. The variation of the FOMs with the task, the observer and especially with the mean number of photons recorded in the image is discussed. Then various standard methods for specifying radiation dose are reviewed and related to the mean number of photons in the image and hence to image quality. Current knowledge of the relation between local radiation dose and the risk of various adverse effects is summarized, and some graphical depictions of the tradeoffs between image quality and risk are introduced. Then various dose-reduction strategies are discussed in terms of their effect on task-based measures of image quality.

    Objectives : To determine the impact of orofacial clefts on the oral health-related quality of life of affected children and whether the oral health-related quality of life of children with orofacial clefts differs among different age groups. To assess whether the responses of children with orofacial clefts differ from the caregivers' perceptions of their child's oral health-related quality of life and compare with data from a control group. Design : Cross-sectional study. Patients/Setting : A total of 75 subjects with cleft lip and/or cleft palate (mean age, 13.0 years) from the Nationwide Children's Hospital Craniofacial Anomalies Clinic, as well as their caregivers, and 75 control subjects (mean age, 13.9 years). Main Outcome Measure : Self-reported oral health-related quality of life measured with the Child Oral Health Impact Profile, a reliable and valid questionnaire designed for use with children and teenagers. Results : Children with orofacial clefts had statistically significant lower quality of life scores than control subjects had for overall oral health-related quality of life, Functional Well-being, and Social Emotional Well-being. There was a statistically significant difference in the interaction of age group and Social-Emotional Well-being between children with orofacial clefts and control children. No statistically significant differences were found between the responses of children with orofacial clefts and their caregivers' reports. Conclusions : Presence of an orofacial cleft significantly decreases overall oral health-related quality of life, Functional Well-being, and Social-Emotional Well-being in children and adolescents. The negative impact of orofacial clefts on Social-Emotional Well-being is greater in 15- to 18-year-olds than in younger age groups. Children with orofacial clefts and their caregivers had very similar evaluations of the child's oral health-related quality of life. PMID:22236323

    2014-01-01

    In the wild, chimpanzees (Pan troglodytes) are often faced with clumped food resources that they may know how to access but abstain from doing so due to social pressures. To better understand how social settings influence resource acquisition, we tested fifteen semi-wild chimpanzees from two social groups alone and in the presence of others. We investigated how resource acquisition was affected by relative social dominance, whether collaborative problem solving or (active or passive) sharing occurred amongst any of the dyads, and whether these outcomes were related to relationship quality as determined from six months of observational data. Results indicated that chimpanzees obtained fewer rewards when tested in the presence of others compared to when they were tested alone, and this loss tended to be greater when paired with a higher ranked individual. Individuals demonstrated behavioral inhibition; chimpanzees who showed proficient skill when alone often abstained from solving the task when in the presence of others. Finally, individuals with close social relationships spent more time together in the problem solving space, but collaboration and sharing were infrequent and sessions in which collaboration or sharing did occur contained more instances of aggression. Group living provides benefits and imposes costs, and these findings highlight that one cost of group living may be diminishing productive individual behaviors. PMID:24695486

    2015-01-01

    The concept of health-related quality of life has a long history in the field of oncology treatment and research. We present a brief history of how the concept has evolved in oncology and the sentinel events in that process. We then focus on advances in measurement science as applied to health-related quality of life measures and argue that a compelling new set of measurement tools is now available, including brief, generic measures with good psychometric qualities (exemplified by the new PROMIS measures and the possibility of a common metric spanning all diseases). The last section of the paper turns to emerging opportunities for these measures, including in clinical trials, healthcare reform, and regulatory deliberations. Our conclusion is that health-related quality of life is more important today than it has ever been, and that the time has come for an even wider adoption of the new measures. PMID:25730723

    Atrial fibrillation is the most common sustained cardiac arrhythmia affecting 1-2% of the population; the prevalence of atrial fibrillation increases with ageing. The condition is associated with high morbidity and mortality, as well as reduced health-related quality of life, particularly in older people. A PubMed, CINAHL, EMBASE and CENTRAL search (January 2003 to April 2013) was conducted using the search terms atrial fibrillation, quality of life, health-related quality of life, older, aged, and over 65 years. In total, 572 papers were identified of which 15 were eligible, including three observational studies, five descriptive comparative studies and seven randomized control trials. Older atrial fibrillation patients (?65 years) were significantly impaired in their health-related quality of life in both physical and mental domains compared to the general population or patients with sinus rhythm. Increasing age, being female or having severe symptoms resulted in poorer health-related quality of life particularly in the physical domain. The review also found that the current treatment of AF including rate and rhythm control strategies improved some aspects of health-related quality of life in atrial fibrillation patients but no specific strategy had a superior effect.

    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

    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.

    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

    Gilles de la Tourette syndrome (GTS) is a neurodevelopmental condition characterised by multiple motor and phonic tics and associated behavioural problems, carrying a significant burden on patients' lives. Although the term health related-quality of life (HR-QOL) has only been used in recent years, several studies have long addressed the impact of GTS on physical, psychological and social aspects of wellbeing of both children and adults with GTS. We set out to answer the question "Is HR-QOL affected by GTS and, if so, in what domains?" by conducting a systematic literature review of published original studies addressing HR-QOL in both children and adult patients with GTS. This review focuses on the current evidence on the impact of GTS on patients' lives, mainly informed by studies using generic functional impairment and HR-QOL measures from the last decade, and expands on the new opportunities introduced by the recently developed GTS-specific HR-QOL scales (GTS-QOL and GTS-QOL-C&A). Analysis of the first decade of studies specifically addressing HR-QOL in GTS suggests that co-morbid conditions are key factors in determining HR-QOL in young patients, whilst the picture is more complex in adults with GTS. These findings offer some general directions for both current clinical practice and future research. PMID:23187148

    In this study, we examined the role of negative emotionality as a moderator of the relations of effortful control and overcontrol (versus undercontrol) with children's externalizing problem behaviors; we also examined the longitudinal relations among these variables. Teachers' and parents' reports of children's negative emotionality, effortful control, overcontrol and externalizing problem behaviors were obtained at T1 (N=199; M age=89.51 months) and again 2 (T2) and 4 years (T3) later. In addition, children's effortful control was assessed with an observed measure of persistence. In a T3 concurrent structural equation model, effortful control, but not overcontrol, was negatively related to children's T3 externalizing problem behaviors. In regression analyses, the negative relation between T3 effortful control and externalizing problem behaviors was strongest at high levels of T3 negative emotionality. In the best-fitting longitudinal structural equation model, both T1 effortful control and T1 overcontrol negatively predicted externalizing problems at T1, whereas T3 effortful control (but not T3 overcontrol) was significantly negatively related to T3 externalizing problem behaviors when controlling for T1 externalizing problem behaviors.

    PubMed

    2004-03-01

    Substance use disorders are the nation's number one health problem, and lie at the root of many public safety and workplace issues. Improving quality of treatment is as important as improving access to treatment. Leadership for improvement must come from many sources: Congress, SAMHSA, state legislatures, state and local treatment agencies, criminal justice, welfare and other public agencies, employers and managed care organizations, providers, and community leaders. We hope that our report helps leaders see ways to improve treatment quality. Our recommendations can be summed up in a single phrase: reward results. We recognize that there are many avenues for treatment quality improvement, including training, credentialing, best practice dissemination, work force development, facility licensing standards, improvement and implementation of new models for treatment of dual diagnosis patients. We believe, however, that rewarding results is essential to motivating action for improvement. We also believe that if providers receive rewards for improved results, they will creatively open new avenues for improvement--a focus on results gives greater freedom than more detailed mandates for change. Finally, we believe that rewards for result may lead to a restructured treatment system with greater stability and correspondingly greater capacity to improve. While we have placed central emphasis on the role of institutional buyers and managers of care, we believe that the voices of patients and families must be heard. People who have progressed to the stage of recovery, and their families, often have essential insight into what did and did not work for them--their personal stories are frequently compelling and persuasive. We also believe that providers of treatment for substance use disorders are profoundly committed to serving their patients, and often have great understanding of what works. Wise managers will listen very carefully and systematically to the voices of consumers, their families, and their providers. We have advocated that buyers reward results as a central strategy for improving quality. We believe that this is the best long-term strategy, not only to effect quality improvement, but also to end stigmatization and increase resources. We wish, in closing, to reemphasize our shared beliefs that adequate resources are essential, that treating persons with substance use disorders is always emotionally challenging and often profoundly frustrating and alienating, and that those on the front line deserve our unequivocal support and our profound gratitude for their service. Legislators should adequately fund public treatment and mandate parity in insurance reimbursement for treatment of substance use disorders. PMID:15285207

    Obesity poses important burdens not only on the individuals whose quality of life is reduced but on national welfare systems that have to face growing premature mortality rates, increase healthcare expenditures to treat obesity-related diseases, and earmark vast amounts of healthcare resources for prevention. The main goal of this paper is to analyze the relationship between excess body weight and different dimensions of health-related quality of life for people 16 years and older and to identify the health dimensions most affected by excess weight. We have drawn data from the Catalonia Health Survey (2006). Our results reveal a relationship between excess weight and health-related quality of life. Even after controlling for socio-economic status and objective health variables, excess weight is shown to have a significant negative effect on health-related quality of life. Subjects responses revealed that the negative effect of excess weight was felt the strongest in the health-related quality of life dimensions of mobility and pain/discomfort. Our results indicate there are important differences among gender and age groups. Women and older people are more likely to suffer from the negative consequences of excess weight. PMID:21853339

    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.

    Objectives Tourette Syndrome (TS) is a chronic neuropsychiatric condition that frequently persists into adulthood. Existing research has identified demographic and symptom-level variables associated with psychopathology and poor quality of life in TS. However, behavior patterns associated with enhanced or adaptive psychological and global functioning among adults with TS have yet to be empirically identified. The current study examined whether tic-specific activity restriction is related to emotional functioning and quality of life in adults with TS. Methods Participants were 509 adults from the Tourette Syndrome Impact Survey who completed self-report measures of demographics, tic severity, emotional functioning, quality of life, and tic related general and social activity restriction. Results Partial correlations controlling for tic severity indicated that tic related general and social activity restriction were significantly correlated with lower quality of life and poorer emotional functioning. Hierarchical linear regression models indicated that activity restriction significantly predicted lower quality of life and poorer emotional functioning when controlling for tic severity and demographic variables. Conclusions Adults who restrict fewer activities due to tics, regardless of tic severity, experience greater quality of life and better emotional functioning. Clinically, adults with chronic tics may benefit from interventions focused on enhancing engagement in valued life activities. PMID:24156871

    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

    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

    The effect of prenatal cocaine exposure (PCE) on externalizing behavior and substance use related problems at 15 years of age was examined. Participants consisted of 358 adolescents (183 PCE, 175 non-cocaine exposed (NCE)), primarily African-American and of low socioeconomic status, prospectively enrolled in a longitudinal study from birth. Regression analyses indicated that the amount of PCE was associated with higher externalizing behavioral problems (? = .15, p = .02). Adolescents with PCE were also 2.8 times (95% CI = 1.38-5.56) more likely to have substance use related problems than their NCE counterparts. No differences between PCE adolescents in non-kinship adoptive/foster care (n = 44) and PCE adolescents in maternal/relative care (n = 139) were found in externalizing behavior or in the likelihood of substance use related problems. Findings demonstrate teratologic effects of PCE persisting into adolescence. PCE is a reliable marker for the potential development of problem behaviors in adolescence, including substance use related problems. PMID:24636687

  11. Relational-database model for improving quality assurance and process control in a composite manufacturing environment

    Gentry, Jeffery D.

    2000-05-01

    A relational database is a powerful tool for collecting and analyzing the vast amounts of inner-related data associated with the manufacture of composite materials. A relational database contains many individual database tables that store data that are related in some fashion. Manufacturing process variables as well as quality assurance measurements can be collected and stored in database tables indexed according to lot numbers, part type or individual serial numbers. Relationships between manufacturing process and product quality can then be correlated over a wide range of product types and process variations. This paper presents details on how relational databases are used to collect, store, and analyze process variables and quality assurance data associated with the manufacture of advanced composite materials. Important considerations are covered including how the various types of data are organized and how relationships between the data are defined. Employing relational database techniques to establish correlative relationships between process variables and quality assurance measurements is then explored. Finally, the benefits of database techniques such as data warehousing, data mining and web based client/server architectures are discussed in the context of composite material manufacturing.

    This study assessed differences between men and women in the association of perceptions of service quality with customer evaluations. Functional (efficiency with which the service is delivered) and relational (customers' emotional benefits, beyond the core performance, related to the social interaction of customers with employees) dimensions of service quality were measured as well as customer satisfaction and loyalty. The sample of 277 customers (191 men, 86 women), surveyed in 29 Mexican hotels, had a mean age of 38.1 yr. (SD=9.7) for men and 34.5 yr. (SD=11.0) for women. To be eligible for survey, customers had to have spent at least one night in the hotel in question. Analysis indicated that the women and men differed in the association of functional and relational dimensions of service quality with their satisfaction and loyalty. Functional service quality was higher for the men than the women, while relational service quality showed greater predictive power for women than for men, although these accounted for only 4% of the customers' satisfaction variance and 6% of the loyalty variance.

    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

    2013-01-01

    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.

Having covered that in detail for 2) to 6) elsewhere, the rest of the current Article is dedicated to the detailed form that 7) and its TR compatible modification takes. I.e. I consider TR implementing foliations, the TR versions of Refoliation Invariance and the associated TR version of hypersurface kinematics and hypersurface deformations. These require a TR counterpart of the Arnowitt--Deser--Misner split.

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

    2013-04-01

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

  5. A test of vegetation-related indicators of wetland quality in the prairie pothole region

    1996-01-01

    This study was part of an effort by the U.S. Environmental Protection Agency to quantitatively assess the environmental quality or 'health' of wetland resources on regional and national scales. During a two-year pilot study, we tested selected indicators of wetland quality in the U.S. portion of the prairie pothole region (PPR). We assumed that the amount of cropland versus non-cropland (mostly grassland) in the plots containing these basins was a proxy for their quality. We then tested indicators by their ability to discriminate between wetlands at the extremes of that proxy. Amounts of standing dead vegetation were greater in zones of greater water permanence. Depth of litter was greater in zones of greater water permanence and in zones of basins in poor-quality watersheds. Amounts of unvegetated bottom were greater in basins in poor-quality watersheds; lesser amounts occurred in all wetlands during a wetter year. Greater amounts of open water occurred during a wetter year and in zones of greater water permanence. When unadjusted for areas (ha) of communities, plant taxon richness was higher in wet-meadow and shallow-marsh zones in good-quality watersheds than in similar zones in poor-quality watersheds. Wet-meadow zones in good-quality watersheds had greater numbers of native perennials than those in poor-quality watersheds. This relation held when we eliminated all communities in good-quality watersheds larger than the largest communities in poor-quality watersheds from the data set. We conclude that although amounts of unvegetated bottom and plant taxon richness in wet-meadow zones were useful indicators of wetland quality during our study, the search for additional such indicators should continue. The value of these indicators may change with the notoriously unstable hydrological conditions in the PPR. Most valuable would be indicators that could be photographed or otherwise remotely sensed and would remain relatively stable under various hydrological conditions. An ideal set of indicators could detect the absence of stressors, as well as the presence of structures or functions, of known value to major groups of organisms.

    Objective: The objective of this study is to describe the oral health status and the factors associated with oral health-related quality of life (OHRQoL) in people aged 65 and older institutionalized in Barcelona in 2009. Study Design: Cross sectional study in 194 elderly. The dependent variable was poor OHRQoL, according to the Geriatric Oral Health Assessment Index (GOHAI). The independent variables were socio-demographic data, last dental visit, subjective and objective oral health status. Robust Poisson regression analysis was used to determine the factors associated with OHRQoL as well as the strengths of association (Prevalence Ratios with respective confidence intervals at 95%). Results: According to GOHAI, 94 women (68.1%) and 36 men (64.3%) had poor OHRQoL. The average DMFT index (number of decayed, missing and filled teeth) was 22.8, with mean 10.2 remaining teeth. According to the Community Periodontal Index only 1.9% were healthy. 33.8% of the sample (35.5% of women and 30.4% of men) presented edentulism, 54.2% needed upper dental prostheses (51.1% of women and 60.7% of men) and 64.7% needed lower ones (61.6% of women and 71.4% of men). Only 7.2% had visited a dentist in the past year (8.8% of women and 3.6% of men). After fitting several multivariate adjusted robust Poisson regression models, poor OHRQoL was found to be associated to self-reporting problems with teeth or gums, self-reporting poor opinion about teeth/gums/denture and also associated to functional edentulism, needing upper denture, but not to socio-demographic factors or time since last dental visit. Conclusions: The study population has poor objective oral health. A high percentage has poor OHRQoL associated to subjective and objective oral health conditions. Dental care is required and these services should be included in the Spanish National Health System. Key words:Oral health, homes for the aged, elderly, self-assessment, quality of life, geriatric oral health assessment index (GOHAI). PMID:23385501

    2010-01-01

    Background It is important to obtain greater insight into health-related quality of life (HRQL) of injury patients in order to document people's pathways to recovery and to quantify the impact of injury on population health over time. We performed a systematic review of studies measuring HRQL in general injury populations with a generic health state measure to summarize existing knowledge. Methods Injury studies (1995-2009) were identified with main inclusion criteria being the use of a generic health status measure and not being restricted to one specific type of injury. Articles were collated by study design, HRQL instrument used, timing of assessment(s), predictive variables and ability to detect change over time. Results Forty one studies met inclusion criteria, using 24 different generic HRQL and functional status measures (most used were SF-36, FIM, GOS, EQ-5D). The majority of the studies used a longitudinal design, but with different lengths and timings of follow-up (mostly 6, 12, and 24 months). Different generic health measures were able to discriminate between the health status of subgroups and picked up changes in health status between discharge and 12 month follow-up. Most studies reported high prevalences of health problems within the first year after injury. The twelve studies that reported HRQL utility scores showed considerable but incomplete recovery in the first year after discharge. Conclusion This systematic review demonstrates large variation in use of HRQL instruments, study populations, and assessment time points used in studies measuring HRQL of general injury populations. This variability impedes comparison of HRQL summary scores between studies and prevented formal meta-analyses aiming to quantify and improve precision of the impact of injury on population health over time.

    Obesity and its relation to quality of life are multifaceted. The purpose of this paper was to contribute evidence to support a framework for understanding the impact of obesity on quality of life in 42 morbidly obese subjects considering a wide number of potential determinants. A model of weight-related quality of life (WRQL) was developed based on the Wilson-Cleary model, considering subjects' weight characteristics, arterial oxygen pressure (PaO(2)), walking capacity (6-minute walk test, 6MWT), health-related quality of life (HRQL; Physical and Mental Component Summaries of the SF-36 PCS/MCS), and WRQL. The model of WRQL was tested with linear regressions and a path analysis, which showed that as PaO(2) at rest increased 6MWT increased. 6MWT was positively associated with the PCS, which in turn was positively related to WRQL along with the MCS. The model showed good fit and explained 38% of the variance in WRQL. PMID:22292114

    Prosser, Lisa A; Corso, Phaedra S

    2007-01-01

    Background Child maltreatment causes substantial morbidity and mortality in the U.S. Morbidity associated with child maltreatment can reduce health-related quality of life. Accurately measuring the reduction in quality of life associated with child maltreatment is essential to the economic evaluation of educational programs and interventions to reduce the incidence of child maltreatment. The objective of this study was to review the literature for existing approaches and instruments for measuring quality-of-life for child maltreatment outcomes. Methods We reviewed the current literature to identify current approaches to valuing child maltreatment outcomes for economic evaluations. We also reviewed available preference-based generic QOL instruments (EQ-5D, HUI, QWB, SF-6D) for appropriateness in measuring change in quality of life due to child maltreatment. Results We did not identify any studies that directly evaluated quality-of-life in maltreated children. We identified 4 studies that evaluated quality of life for adult survivors of child maltreatment and 8 studies that measured quality-of-life for pediatric injury not related to child maltreatment. No study reported quality-of-life values for children younger than age 3. Currently available preference-based QOL instruments (EQ-5D, HUI, QWB, SF-6D) have been developed primarily for adults with the exception of the Health Utilities Index. These instruments do not include many of the domains identified as being important in capturing changes in quality of life for child maltreatment, such as potential for growth and development or psychological sequelae specific to maltreatment. Conclusion Recommendations for valuing preference-based quality-of-life for child maltreatment will vary by developmental level and type of maltreatment. In the short-term, available multi-attribute utility instruments should be considered in the context of the type of child maltreatment being measured. However, if relevant domains are not included in existing instruments or if valuing health for children less than 6 years of age, direct valuation with a proxy respondent is recommended. The choice of a proxy respondent is not clear in the case of child maltreatment since the parent may not be a suitable proxy. Adult survivors should be considered as appropriate proxies. Longer-term research should focus on identifying the key domains for measuring child health and the development of preference-based quality-of-life instruments that are appropriate for valuing child maltreatment outcomes.

    Objective: Racial discrimination has been identified as an important predictor of alcohol-related outcomes for African Americans. The goal of the current study was to extend previously found links between lifetime discrimination, alcohol use, and alcohol problems as well as to elucidate the affective mechanisms underlying these associations, as moderated by gender. Method: A multiple-groups structural equation model was computed using survey data collected from 619 students from a historically Black college/university. Results: The final model provided excellent fit to the data, explaining 6% of the variance in alcohol consumption and 37% of the variance in alcohol problems. Discrimination was a significant predictor of alcohol-related problems but not, by and large, level of use. For men, anger—but not discrimination-specific anger—was a significant partial mediator of the link between discrimination and both alcohol use and alcohol problems. Depression partially mediated the link between discrimination and alcohol problems for both men and women. Conclusions: The results suggest that, for African Americans whose drinking leads to drinking-related problems, discrimination and poor affective self-regulation are highly relevant and predictive factors, especially for men.

    Catheter-related sepsis (CRS) is a clinical problem gaining increasing attention in the literature. Before strategies for reducing the incidence of CRS can be identified, a consistent definition of the problem must be developed. Critical thinking is an intellectual process used to reflect upon a topic of interest. The critical thinking process provides a framework for comprehensive analysis of patient care problems. The article describes the critical thinking process and proposes a model of critical thinking for practicing nurses. This model is applied to the development of comprehensive definitions for CRS that may be used by neonatal nurses for clinical and research purposes. PMID:9214951

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

    Background As Iran started to experience population ageing, it is important to consider and address the elderly people's needs and concerns, which might have direct impacts on their well-being and quality of life. There have been only a few researches into different aspects of life of the elderly population in Iran including their health-related quality of life. The purpose of this study was to measure health-related quality of life (HRQoL) of elderly Iranians and to identify its some determinant factors. Methods This was a cross-sectional survey of a random sample of community residents of Tehran aged 65 years old and over. HRQoL was measured using the Short From Health Survey (SF-36). The study participants were interviewed at their homes. Uni-variate analysis was performed for group comparison and logistic regression analysis conducted to predict quality of life determinants. Results In all, 400 elderly Iranian were interviewed. The majority of the participants were men (56.5%) and almost half of the participants were illiterate (n = 199, 49.8%). Eighty-five percent of the elderly were living with their family or relatives and about 70% were married. Only 12% of participants evaluated their economic status as being good and most of people had moderate or poor economic status. The mean scores for the SF-36 subscales ranged from 70.0 (SD = 25.9) for physical functioning to 53.5 (SD = 29.1) for bodily pain and in general, the respondents significantly showed better condition on mental component of the SF-36 than its physical component (mean scores 63.8 versus 55.0). Performing uni-variate analysis we found that women reported significantly poorer HRQoL. Multiple logistic regression analysis showed that for the physical component summary score of the SF-36, age, gender, education and economic status were significant determinants of poorer physical health-related quality of life; while for the mental component summary score only gender and economic status were significant determinants of poorer mental health-related quality of life. The analysis suggested that the elderly people's economic status was the most significant predictor of their HRQoL. Conclusion The study findings, although with a small number of participants, indicate that elderly people living in Tehran, Iran suffer from relatively poor HRQoL; particularly elderly women and those with lower education. Indeed to improve quality of life among elderly Iranians much more attention should be paid to all aspects of their life including their health, and economic status. PMID:18808675

    ABSTRACT: Background Acne impairs quality of life, but its effect on different races/ethnicities is unclear. This study evaluated racial/ethnic differences in acne-related quality of life and psychological symptoms among female adults. Methods A Web-based survey was conducted with U.S. female adults (25–45 years old) with facial acne (?25 visible lesions). Outcomes included sociodemographics, clinical characteristics, acne-related quality of life (Acne-Specific Quality of Life Questionnaire), psychological symptoms (Patient Health Questionnaire), and work/school productivity. Racial/ethnic differences were evaluated using descriptive statistics and analysis of variance/chi-square analyses. Results Three-hundred twelve subjects (Black = 30.8%, Hispanic = 17.6%, Asian/other = 17.3%, White = 34.3%) completed the survey (mean age = 35.3 ± 5.9 years). Acne negatively impacted quality of life for all subjects. Black subjects reported significantly less negative impact on self-perception versus Asian/other (Black = 12.6 ± 9.9, Asian/other = 8.4 ± 8.6; p = .05). Social functioning was less negatively impacted in White and Black subjects versus Asian/other (White = 12.7 ± 7.5, Asian/other = 8.4 ± 7.8, p < .05; Black = 12.1 ± 9.2, Asian/other = 8.4 ± 7.8, p = .06). Over one third (total sample = 40.7%, Black = 31.3%, Hispanic = 36.4%, Asian/other = 50.0%, White = 46.7%) reported moderate/severe anxiety/depression symptoms. Acne also impacted ability to concentrate on work/school. Conclusion Racial/ethnic differences were observed in acne-related quality of life and psychological symptoms in female adults; acne negatively impacted self-perceptions and social/emotional functioning.

    STUDY QUESTION Is consumption of sugar-sweetened beverages (SSB) associated with semen quality? SUMMARY ANSWER Higher consumption of SSB was associated with lower sperm motility among healthy, young men. WHAT IS KNOWN ALREADY The existing literature on the potential role of SSBs on male reproductive function is scarce and primarily focused on the relation between caffeinated beverages and semen quality. However, a rodent model suggests that SSBs may hamper male fertility. STUDY DESIGN, SIZE, DURATION The Rochester Young Men's Study; a cross-sectional study of 189 healthy young men carried out at the University of Rochester during 2009–2010. PARTICIPANTS/MATERIALS, SETTING, METHODS Men aged 18–22 years provided semen and blood samples, underwent a physical examination and completed a previously validated food frequency questionnaire (FFQ). Linear regression was used to analyze the association of SSBs with sperm parameters and reproductive hormone levels while adjusting for potential confounders. MAIN RESULTS AND THE ROLE OF CHANCE SSB intake was inversely related to progressive sperm motility. Men in the highest quartile of SSB intake (?1.3 serving/day) had 9.8 (95% CI: 1.9,17.8) percentage units lower progressive sperm motility than men in the lowest quartile of intake (<0.2 serving/day) (P, trend = 0.03). This association was stronger among lean men (P, trend = 0.005) but absent among overweight or obese men (P, trend = 0.98). SSB intake was unrelated to other semen quality parameters or reproductive hormones levels. LIMITATIONS, REASONS FOR CAUTION As in all cross-sectional studies, causal inference is limited. An additional problem is that only single semen sample was obtained from each subject. WIDER IMPLICATIONS OF THE FINDINGS To our knowledge, this is the first report on the relation between SSB intake and low semen quality beyond the contribution of caffeinated beverages. While our findings are in agreement with recent experimental data in rodents, more studies are required to draw conclusions on the relation of SSB with semen quality or male infertility.

    Using the abbreviated World Health Organization Quality of Life (WHOQOL-Bref) questionnaire, we evaluated the effect of exposure to smoke from wood combustion while cooking on health-related quality of life (HRQL) in 85 women using wood and 85 women using liquefied petroleum gas (LPG) as cooking fuel in India. Age, years of cooking and hours spent daily in the kitchen were similar between women in the two groups. WHOQOL-Bref transformed scores in psychological, social relationships and environment domains were significantly lower in women in using wood than in those using LPG, suggesting that HRQL was impaired across domains among these women.

    The present article focuses on couple types based on 2 personality traits, attachment security and neuroticism, as they relate to 2 facets of the marital relationship--a global evaluation of relationship quality and dyadic closeness-distance. The sample consisted of 248 married couples who completed measures of attachment anxiety and avoidance, neuroticism, and marital quality, as well as levels of closeness reported over 7 consecutive days. Cluster analyses yielded 3 types of dyadic attachment configurations (secure, fearful avoidant, and insecure-mixed) and 4 types of dyadic neuroticism (low couple neuroticism, high couple neuroticism, wife neuroticism, and husband neuroticism). Significant differences were found among attachment and neuroticism dyadic types in marital quality. The findings are discussed in terms of the viability of dyadic types based on individual traits, implying that attachment security yields itself to dyadic conceptualization more than neuroticism.

    Overall, the findings show that exhaust fans basically provide small amounts of ventilation compensation. By monitoring the common indoor air pollutants (radon, formaldehyde, carbon monoxide, nitrogen dioxide, and water vapor), it was found that the quality of the indoor air was not adversely affected by the use of exhaust fans. Nor did their use provide any measurable or significant benefits since no improvement in air quality was ascertained. While exhaust fans of this small size did not increase radon, which is the contaminant of most concern, the researchers caution that operation of a larger fan or installation in a very tight home could result in higher levels because depressurization is greater. The daily energy consumption for use of these appliances during the heating season was calculated to be 1.5 kilowatt hours or approximately 3% of the energy consumption in the study homes. The information collected in this collaborative field study indicates that the use of these particular ventilation systems has no significant effect on indoor air quality.

    The transfer matrix method is usually employed to study problems described by $N$ equations of matrix Sturm-Liouville (MSL) kind. In some cases a numerical degradation (the so called $\\Omega d$ problem) appears thus impairing the performance of the method. We present here a procedure that can overcome this problem in the case of multilayer systems having piecewise constant coefficients. This is performed by studying the relations between the associated transfer matrix and other transfer matrix variants. In this way it was possible to obtain the matrices which can overcome the $\\Omega d$ problem in the general case and then in problems which are particular cases of the general one. In this framework different strategies are put forward to solve different boundary condition problems by means of these numerically stable matrices. Numerical and analytic examples are presented to show that these stable variants are more adequate than other matrix methods to overcome the $\\Omega d$ problem. Due to the ubiquity of the MSL system, these results can be applied to the study of many elementary excitations in multilayer structures.

  8. Handling qualities related to stall/spin accidents of supersonic fighter aircraft

    1984-01-01

    This paper reviews the handling qualities which influence the high angle of attack (AOA) behavior of supersonic fighter aircraft in order to obtain a clearer understanding of the causes of stall/spin accidents. The results show that, because modern fighters suffer more serious consequences when control is lost, good handling qualities are essential for safe operation at high AOA. Relaxed static stability used on some fighter aircraft can result in control problems at high AOA owing to inertia coupling and the difficulty of a recovery from a deep stall. Indications are that the use of departure/spin resistance and an automatic spin prevention system will greatly improve the safety record for modern supersonic fighters.

    Absract Objectives Tuberculosis is one of the oldest infections known to affect humans. The aim of the study was to assess the quality of life including physiological, general health perception and social role functioning among patients with tuberculosis in Hamadan, Western Iran. Methods A cross sectional analytical study was conducted between December 2009 and March 2011, the quality of life scores of 64 tuberculosis cases were measured by SF-36 questionnaire before treatment, after the initial phase and at the end of treatment and were compared with those of 120 controls. The association of the quality of life with age, type of tuberculosis, sputum smear, duration of disease, and the stage of treatment were assessed among the patients. Results Before treatment, all scores of tuberculosis patients were lower than those of the controls (p<0.05). The patients’ score increased significantly after two months of treatment (p=0.01), but the difference was not significant between two and six months after treatment (p=0.07). The lowest score in tuberculosis patients was related to physical functioning and energy (45 ± 42, 44 ± 24, respectively). Conclusion According to the results, tuberculosis patients still have a low quality of life in spite of receiving new care strategies. Therefore, enhancement in quality of life may improve adherence to anti-tuberculosis treatment, functioning and well-being of patients with tuberculosis. PMID:24715935

    Objective. To prospectively evaluate the impact of parathyroidectomy on swallowing-related quality of life using the Swallowing Quality Of Life (SWAL-QOL) validated outcomes assessment tool. Background. Many patients with primary hyperparathyroidism report nonspecific symptoms, such as fatigue, irritability, cognitive impairment, sleep disturbances, and dysphagia. To date, there have been no prospective studies evaluating swallowing function before and after parathyroid surgery. Methods. Patients undergoing parathyroidectomy from September 2007 to January 2009 completed the SWAL-QOL questionnaire before and one year after surgery. Data were collected on demographic and clinicopathologic variables. Comparisons were made to determine the effect of surgery on patients' perceptions of swallowing function. Results. Of 151 eligible patients, 102 (68%) completed the study. The mean patient age was 60 years, and 79% were female. A total of 73 patients (67%) had minimally invasive parathyroidectomies, whereas the remainder had bilateral explorations. In all, 83 patients (81%) had a parathyroid adenoma, 16 patients (16%) had hyperplasia, and 3 patients (3%) had a double adenoma on final pathologic interpretation. Mean preoperative SWAL-QOL scores were <90 for 4 of the 11 domains, indicating the perception of oropharyngeal dysphagia and diminished quality of life. Following parathyroidectomy, significant improvements were demonstrated in eight SWAL-QOL domains. Conclusions. Many patients with parathyroid disease have the perception of abnormal swallowing function. In these patients with symptoms of dysphagia, parathyroid surgery leads to significant improvements in many aspects of swallowing-related quality of life measured by the SWAL-QOL instrument. This study represents the first use of a condition-specific instrument to assess swallowing-related quality of life for patients with parathyroid disease before and after parathyroid surgery.

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

    Phytoplankton community structure in coastal areas is a result of various environmental factors such as nutrients, light, grazing, temperature, and salinity. The Yucatan Peninsula is a karstic tropical region that is strongly influenced by submerged groundwater discharge (SGD) into the coastal zone. Phytoplankton community structure and its relationship with regional and local water quality variables were studied in four ports of the northwestern Yucatan Peninsula. Water quality was strongly related to SGD, and variations in phytoplankton community structure were related to local nutrient loading and hydrographic conditions, turbulence, and human impacts. Our study provides an ecological baseline for the Yucatan Peninsula and serves as a basis for establishing monitoring programs to predict changes at sites with high hydrological variation and in developing an early alert system for harmful toxic algal blooms.

    2013-01-01

    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

    Background Obsessive-compulsive disorder (OCD) affects young adults and has great impact on the social, emotional and work spheres. Methods We measured perceived quality of life (QOL) in OCD patients, in order to analyse socio-demographic and clinical factors that may be associated with QOL perception. 64 OCD outpatients were assessed with the Mini International Neuropsychiatric Interview for DSM-IV, the Yale-Brown Obsessions and Compulsions scale (Y-BOCS), Hamilton's depression scale and the SF-36 self-administered global QOL perception scale. Results We found a correlation among Hamilton's scale scores and all SF-36 subscales. The severity of the obsessive-compulsive disorder was correlated with all SF-36 subscales and with the highest scores in Hamilton's scale. The obsessions subscale was correlated to all SF-36 subscales, while the compulsions subscale was correlated only to social functioning, emotional role, mental health and vitality. Compulsions were not related to general health perception. There were significant differences between OCD patients and the Spanish general population in all SF-36 subscales except those related to physical health and pain. Gender, age, age of onset of the disorder, years of evolution and marital status of the patients did not significantly affect quality of life perception. Being employed was related to better scores in the subscale of physical role. Patients with medical comorbidity scored lower in the subscales of general health, social functioning and mental health. Patients with comorbid psychiatric disorders had worse scores in the subscales of pain, general health, social functioning and mental health. Conclusion Quality of life perception was different in OCD patients and the general population. Quality of life perception was related to severity of the disorder, physical and psychiatric comorbidity and employment status. PMID:16684346

    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.

    The purpose of the study was to assess the quality of life, physical function, self-motivation, and self-perception of skeletally mature patients with spina bifida and scoliosis. This is a prospective study on 19 skeletally mature patients with a mean age of 21.4 years. Several questionnaires were used for the study: Activities Scale for Kids, Quality of Life in Spina Bifida Questionnaire, The Health Self-Determinism Index for Children, Harter's Self-Perception Profile for Adolescents, and the Spina Bifida Spine Questionnaire. This study found no association between spinal deformity or other features related to spina bifida and self-perception, motivation, and overall physical function. More severe scoliosis affects quality of life and is related to the degree of pelvic obliquity and the age of the patients. Individuals with motor-level dysfunction below L3 had significantly better overall physical function compared with those with a higher level of lesions. This was the only factor found to affect physical function. Our findings suggest that most limitations in patients with spina bifida are not related to the degree of scoliosis but to other associated disabilities. PMID:23197183

    Objective The purpose of the present study was to examine the relationship between the use of senior center and health-related quality of life in Korean older adults. Methods A questionnaire survey was conducted to two types of older adults who lived in Busan, Korea: 154 older adults who used a senior center and 137 older adults who did not use a senior center. The Korean version of short-form 36-item health survey was administered to assess the health-related quality of life. Demographic variables were obtained from a questionnaire. These were gender, age, family status, marital status, education, monthly income, present illness, body mass index and physical activity. Results The 8-domain scales of physical function and role-physical were significantly higher in the users of the senior center compared with the non-users (F=4.87, p=0.027 and F=7.02, p=0.009, respectively). The 8-domain scales of vitality was also significantly higher in the users of the senior center compared with the non-users (F=7.48, p=0.007). Conclusions The present study showed that the users of the senior center have higher physical function, role-physical and vitality compared with the non-users. These findings suggest that although the results are unable to specify causal relationships using the senior center may lead to some improvement in health-related quality of life. PMID:21894063

    Background This article reports on the relationship between cultural influences on life style, coping style, and sleep in a sample of female Portuguese immigrants living in Germany. Sleep quality is known to be poorer in women than in men, yet little is known about mediating psychological and sociological variables such as stress and coping with stressful life circumstances. Migration constitutes a particularly difficult life circumstance for women if it involves differing role conceptions in the country of origin and the emigrant country. Methods The study investigated sleep quality, coping styles and level of integration in a sample of Portuguese (N = 48) and Moroccan (N = 64) immigrant women who took part in a structured personal interview. Results Sleep quality was poor in 54% of Portuguese and 39% of Moroccan women, which strongly exceeds reports of sleep complaints in epidemiologic studies of sleep quality in German women. Reports of poor sleep were associated with the degree of adoption of a German life style. Women who had integrated more into German society slept worse than less integrated women in both samples, suggesting that non-integration serves a protective function. An unusually large proportion of women preferred an information-seeking (monitoring) coping style and adaptive coping. Poor sleep was related to high monitoring in the Portuguese but not the Moroccan sample. Conclusion Sleep quality appears to be severely affected in women with a migration background. Our data suggest that non-integration may be less stressful than integration. This result points to possible benefits of non-integration. The high preference for an information-seeking coping style may be related to the process of migration, representing the attempt at regaining control over an uncontrollable and stressful life situation.

    Background: American Optometric Association defines Computer Vision Syndrome (CVS) as “complex of eye and vision problems related to near work which are experienced during or related to computer use.” This happens when visual demand of the tasks exceeds the visual ability of the users. Even though problems were initially attributed to computer-related activities subsequently similar problems are also reported while carrying any near point task. Jewellery manufacturing activities involves precision designs, setting the tiny metals and stones which requires high visual attention and mental concentration and are often near point task. It is therefore expected that the workers engaged in jewellery manufacturing may also experience symptoms like CVS. Aim: Keeping the above in mind, this study was taken up (1) To identify the prevalence of symptoms like CVS among the workers of the jewellery manufacturing and compare the same with the workers working at computer workstation and (2) To ascertain whether such symptoms have any permanent vision-related problems. Setting and Design: Case control study. Materials and Methods: The study was carried out in Zaveri Bazaar region and at an IT-enabled organization in Mumbai. The study involved the identification of symptoms of CVS using a questionnaire of Eye Strain Journal, opthalmological check-ups and measurement of Spontaneous Eye Blink rate. The data obtained from the jewellery manufacturing was compared with the data of the subjects engaged in computer work and with the data available in the literature. Statistical Analysis: A comparative inferential statistics was used. Results and Conclusion: Results showed that visual demands of the task carried out in jewellery manufacturing were much higher than that of carried out in computer-related work. PMID:26023269

    Moisture problems in buildings have in a number of studies been shown to increase the risk for respiratory symptoms. The study Dampness in Buildings and Health (DBH) was initiated with the aim to identify health relevant exposures related to dampness in buildings. A questionnaire study about home environment with a focus on dampness problems and health was conducted in one county of Sweden (8,918 homes, response rate 79%). Building characteristics that were associated with one or more of the dampness indicators were for single-family houses, older houses, flat-roofed houses built in the 1960s and 1970s, houses with a concrete slab on the ground that were built before 1983. Moreover, tenancy and earlier renovation due to mould or moisture problems was strongly associated with dampness. A perception of dry air was associated with window-pane condensation, e.g. humid indoor air. PMID:19557598

    Identifying children at risk for reading problems or dyslexia at kindergarten age could improve support for beginning readers. Brain event-related potentials (ERPs) were measured for temporally complex pseudowords and corresponding non-speech stimuli from 6.5-year-old children who participated in behavioral literacy tests again at 9 years in the second grade. Children who had reading problems at school age had larger N250 responses to speech and non-speech stimuli particularly at the left hemisphere. The brain responses also correlated with reading skills. The results suggest that atypical auditory and speech processing are a neural-level risk factor for future reading problems.

  4. A continuum of relative equilibria in the five-body problem

    1999-03-01

    It is generally believed that the set of relative equilibria equivalence classes in the Newtonian n-body problem, for a given set of positive masses, is finite. However, the result has only been proven for n=3 and remains a difficult, open question for n?4 [A. Wintner, Princeton Math. Ser. 5, 215, Princeton University Press, Princeton, NJ, 1941; S. Smale, Mathematical Intelligencer 20 (1998) 7-15]. We demonstrate that the condition for the masses being positive is a necessary one by finding a continuum of relative equilibria in the five-body problem which (unfortunately) includes one negative mass. This family persists in similar potential functions, including the logarithmic potential used to describe the motion of point vortices in a plane of fluid.

    Problems related to the design of the hardware for an integrated aircraft electronic system are considered. Taxonomies of concurrent systems are reviewed and a new taxonomy is proposed. An informal methodology intended to identify feasible regions of the taxonomic design space is described. Specific tools are recommended for use in the methodology. Based on the methodology, a preliminary strawman integrated fault tolerant aircraft electronic system is proposed. Next, problems related to the programming and control of inegrated aircraft electronic systems are discussed. Issues of system resource management, including the scheduling and allocation of real time periodic tasks in a multiprocessor environment, are treated in detail. The role of software design in integrated fault tolerant aircraft electronic systems is discussed. Conclusions and recommendations for further work are included.

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

    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

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

    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.

    Direct and indirect relations among maternal depression, maternal Expressed Emotion (EE: Self- and Child-Criticism), child internalizing and externalizing symptoms, and child attachment were examined. Participants were mothers with depression (n = 130) and comparison mothers (n = 68) and their toddlers (M age = 20 mo.; 53% male). Assessments included the Diagnostic Interview Schedule (maternal depression); the Five Minute Speech Sample (EE); the Child Behavior Checklist (toddler behavior problems); the Strange Situation (child attachment). Direct relations were significant linking: 1) maternal depression with both EE and child functioning; 2) Child-Criticism with child internalizing and externalizing symptoms; 3) Self-Criticism with child attachment. Significant indirect relations were found linking maternal depression with: 1) child externalizing behaviors via Child-Criticism; 2) child internalizing behaviors via Self- and Child-Criticism; and 3) child attachment via Self-Criticism. Findings are consistent with a conceptual model in which maternal EE mediates relations between maternal depression and toddler socio-emotional functioning. PMID:22146899

    Summary The QOLIBRI (Quality of Life after Brain Injury) is a new international health-related quality of life (HRQoL) instrument developed for assessing the consequences of traumatic brain injury (TBI). We report the results of the Italian validation of the QOLIBRI. A total of 147 participants with TBI who had previously been discharged from the Santa Lucia Foundation rehabilitation hospital were recruited to investigate the concurrent validity of the Italian version of the QOLIBRI and to compare this instrument with several functional and cognitive-behavioral scales, taking into account various clinical parameters. The QOLIBRI met the standard criteria for internal consistency, homogeneity and test-retest reliability. The results suggest that it is very sensitive in relation to outcome as measured by the Extended Glasgow Outcome Scale (GOS-E) and other instruments for functional assessment of disability, emotions and subjective health status, including the Hospital Anxiety and Depression Scale and the Short-Form 36. The QOLIBRI avoids some of the limitations of traditional scales for quantifying residual functional capacity, such as the Glasgow Outcome Scale and the GOS-E, and may contribute to the achievement of better quality-controlled care, medical decision-making, rehabilitation planning, and measurement of well-being and HRQoL from the patient’s perspective. However, a longitudinal study is needed to assess the responsiveness of the QOLIBRI to changes over time. PMID:25473736

    Antiretroviral (ARV) treatment for HIV infection has resulted in significant improvement in immunologic and virologic parameters, as well as a reduction in AIDS-defining illnesses and death. Over 25 medications are approved for use, usually in combination regimens of three or four ARVs. Several ARVs are now available as combinatorial products, which have been associated with better adherence. However, while ARV therapy has prolonged life, ARVs also pose a challenge for quality of life as they can cause significant side effects in addition to the potential for drug toxicity and interaction. Given the many complications, side effects and symptoms of HIV/AIDS in addition to associated medical and psychiatric co-morbidities, the need to understand and assess how these interactions may affect health-related quality of life (HRQOL) has grown. Numerous instruments (some validated, others not) are available and have been applied to understanding how ARV treatment affects HRQOL in those with HIV infection, both in clinical trials and clinical practice. In general, ARV treatment improves HRQOL, but this is dependent on the population being studied, the HRQOL instrument being used and the timeframe during which HRQOL has been studied. This article provides a review of the literature on quality of-life assessment as it relates to ARV treatment in developed countries and briefly reviews the HRQOL instruments used, how they have been applied to ARV utilization, and where future research should be applied in HRQOL assessment and HIV infection.

  13. End-State Relative Equilibria in the Sphere-Restricted Full Three-Body Problem

    The Sphere-Restricted Full Three-Body Problem studies the motion of three finite density spheres as they interact under surface and gravitational forces. When accounting for the dissipation of energy, full-body systems may achieve minimum energy states that are unatainable in the classic treatment of the N-Body Problem. This serves as a simple model for the mechanics of rubble pile asteroids, interacting grains in a protoplanetary disk, and potentially the interactions of planetary ring particles. Previous studies of this problem have been performed in the case where the three spheres are of equal size and mass, with all possible relative equilibria and their stability having been identified as a function of the total angular momentum of the system. These studies uncovered that at certain levels of angular momentum there exists more than one stable relative equilibrium state. Thus a question of interest is which of these states a dissipative system would preferentially settle in provided some domain of initial conditions, and whether this would be a function of the dissipation parameters. Using perfectly-rigid dynamics, three-equal-sphere systems are simulated in a purpose-written C-based code to uncover these details. Results from this study are relevant to the mechanics and dynamics in small solar system bodies where relative forces are not great enough to compromise the rigidity of the constituents.

    Purpose: While undergoing a hospital residency training program, residents often suffer anxiety and stress. This study aims to evaluate the change in health-related quality of life and happiness among internal medicine residents, and identify prognostic factors. Methods: Thirty-eight residents in the Ramathibodi Hospital internal medicine training program completed the World Health Organization Quality of Life-BREF and happiness Measures questionnaires at three time points: commencement, day 100, and the end of the second year of training. Confidence, expectations, anxiety, and general health were rated. Analyses were performed with mixed linear regression. Results: Financial problems were reported for 16 residents (42.1%). At baseline, most residents had moderate-to-very high confidence, expectations, and general health but also moderate-to-very high anxiety. The health-related quality of life score was highest in the social domain followed by the environmental, psychological, and physical domains. Their psychological, physical, social, and environmental scores significantly decreased after enrollment. Their happiness and general health scores were significantly reduced after enrollment. The training program duration was negatively associated with all domains. Residents with greater confidence had higher health-related quality of life scores in the physical, psychological, and environmental domains. Moreover, their general health was positively associated with the social and environmental domains. Conclusion: A reduction in health-related quality of life and happiness under the internal medicine residency program is reported. High confidence and good physical health may counterbalance the decline in health-related quality of life and happiness. PMID:25748482

    The quality of streams and relations to environmental variables in Johnson County, northeastern Kansas, were evaluated using water, streambed sediment, land use, streamflow, habitat, algal periphyton (benthic algae), and benthic macroinvertebrate data. Water, streambed sediment, and macroinvertebrate samples were collected in March 2007 during base flow at 20 stream sites that represent 11 different watersheds in the county. In addition, algal periphyton samples were collected twice (spring and summer 2007) at one-half of the sites. Environmental data including water and streambed-sediment chemistry data (primarily nutrients, fecal-indicator bacteria, and organic wastewater compounds), land use, streamflow, and habitat data were used in statistical analyses to evaluate relations between biological conditions and variables that may affect them. This report includes an evaluation of water and streambed-sediment chemistry, assessment of habitat conditions, comparison of biological community attributes (such as composition, diversity, and abundance) among sampling sites, placement of sampling sites into impairment categories, evaluation of biological data relative to environmental variables, and evaluation of changes in biological communities and effects of urbanization. This evaluation is useful for understanding factors that affect stream quality, for improving water-quality management programs, and for documenting changing conditions over time. The information will become increasingly important for protecting streams in the future as urbanization continues. Results of this study indicate that the biological quality at nearly all biological sampling sites in Johnson County has some level of impairment. Periphyton taxa generally were indicative of somewhat degraded conditions with small to moderate amounts of organic enrichment. Camp Branch in the Blue River watershed was the only site that met State criteria for full support of aquatic life in 2007. Since 2003, biological quality improved at one rural sampling site, possibly because of changes in wastewater affecting the site, and declined at three urban sites possibly because of the combined effects of ongoing development. Rural streams in the western and southern parts of the county, with land-use conditions similar to those found at the State reference site (Captain Creek), continue to support some organisms normally associated with healthy streams. Several environmental factors contribute to biological indicators of stream quality. The primary factor explaining biological quality at sites in Johnson County was the amount of urbanization upstream in the watershed. Specific conductance of stream water, which is a measure of dissolved solids in water and is determined primarily by the amount of groundwater contributing to streamflow, the amount of urbanization, and discharges from wastewater and industrial sites, was strongly negatively correlated with biological stream quality as indicated by macroinvertebrate metrics. Concentration of polycyclic aromatic hydrocarbons (PAHs) in streambed sediment also was negatively correlated with biological stream quality. Individual habitat variables that most commonly were positively correlated with biological indicators included stream sinuosity, buffer length, and substrate cover diversity. Riffle substrate embeddedness and sediment deposition commonly were negatively correlated with favorable metric scores. Statistical analysis indicated that specific conductance, impervious surface area (a measure of urbanization), and stream sinuosity explained 85 percent of the variance in macroinvertebrate communities. Management practices affecting environmental variables that appear to be most important for Johnson County streams include protection of stream corridors, measures that reduce the effects of impervious surfaces associated with urbanization, reduction of dissolved solids in stream water, reduction of PAHs entering streams and

    Food availability comprises a complex interaction of factors that integrates abundance, taxonomic composition, accessibility, and quality of the prey base. The relationship between food availability and reproductive performance can be assessed via the nutritional stress (NSH) and junkfood (JFH) hypotheses. With respect to reproductive success, NSH posits that a deficiency in any of the aforementioned metrics can have a deleterious effect on a population via poor reproductive success. JFH, a component of NSH, posits specifically that it is a decline in the quality of food (i.e. energy density and lipid content) that leads to poor reproductive success. We assessed each in relation to reproductive success in a piscivorous seabird, the black-legged kittiwake Rissa tridactyla. We measured productivity, taxonomic composition, frequency, size, and quality of meals delivered to nestlings from 1996 to 1999 at 6 colonies in Alaska, USA, 3 each in Prince William Sound and Lower Cook Inlet. Productivity varied widely among colony-years. Pacific herring Clupea pallasi, sand lance Ammodytes hexapterus, and capelin Mallotus villosus comprised ca. 80% of the diet among colony-years, and each was characterized by relatively high energy density. Diet quality for kittiwakes in this region therefore remained uniformly high during this study. Meal delivery rate and meal size were quite variable among colony-years, however, and best explained the variability in productivity. Parent kittiwakes appeared to select prey that were energy dense and that maximized the biomass provisioned to broods. While these results fail to support JFH, they do provide substantial support for NSH. ?? Inter-Research 2006.

  19. Exploring quality of life as an intervention outcome among women with stress-related disorders participating in work rehabilitation

    2015-01-01

    Background Findings from quality of life studies are often inconclusive for reasons such as: i) estimates may address different aspects of quality of life and thus produce different outcomes; ii) quality of life is largely determined by self-factors; and iii) people with a long-term condition rate their quality of life better than those who have had their condition for a short duration. This makes quality of life a complex phenomenon to measure. Aims The above explanations served as hypotheses for this methodologically oriented paper, based on a longitudinal study on women with stress-related disorders receiving work rehabilitation. Methods Eighty-four women participating in a lifestyle intervention or care as usual were compared. Self-ratings of “general quality of life” and a summarized “satisfaction with different life domains” index (according to Manchester Short Assessment of Quality of Life) and two self-factors (self-esteem and self-mastery) were administered at admission and a 6-month follow-up. Participant age and amount of months on sick leave prior to rehabilitation were used as two proxies of duration of the condition. Results General quality of life distinguished between the groups, whereas satisfaction with life domains did not. Self-esteem and self-mastery were related to both quality of life aspects. Age was related to both estimates of quality of life, whereas duration of sick leave was unrelated to both. Conclusion General quality of life and satisfaction with life domains produced different results. Outcome studies should apply more than one operationalization of quality of life and self-factors should be considered as important determinants of quality of life. Duration of the condition needs to be acknowledged as well when interpreting levels of quality of life, although the current study could not present any clear-cut findings in this respect.

    Most previous research on indoor environments and health has studied school children or occupants in non-school settings. This investigation assessed building-related health symptoms and classroom characteristics via telephone survey of New York State school teachers. Participants were asked about 14 building-related symptoms and 23 classroom characteristics potentially related to poor indoor air quality (IAQ). Poisson regression analysis was used to assess the relationship between these symptoms and each classroom characteristic, controlling for potential confounders. About 500 teachers completed the survey. The most frequently reported classroom characteristics included open shelving (70.7%), food eaten in class (65.5%), dust (59.1%), and carpeting (46.9%). The most commonly reported symptoms included sinus problems (16.8%), headache (15.0%), allergies/congestion (14.8%), and throat irritation (14.6%). Experiencing one or more symptoms was associated most strongly with reported dust (relative risk (RR) = 3.67; 95% confidence interval (CI): 2.62-5.13), dust reservoirs (RR = 2.13; 95% CI: 1.72-2.65), paint odors (RR = 1.73; 95% CI: 1.40-2.13), mold (RR = 1.71; 95% CI: 1.39-2.11), and moldy odors (RR = 1.65 95% CI: 1.30-2.10). Stronger associations were found with increasing numbers of reported IAQ-related classroom characteristics. Similar results were found with having any building-related allergic/respiratory symptom.

    The problem of computing spanning trees along with specific con- straints is mostly NP-hard. Many approximation and stochastic algorithms which yield a single solution, have been proposed. In this paper, we formulate the generic multi-objective spanning tree (MOST) problem and consider edge-cost and di- ameter as the two objectives. Since the problem is hard, and the Pareto-front is unknown, the

    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%.

    The U.S. Geological Survey well profiler was used to describe arsenic-related water quality with well depth and identify zones yielding water with high arsenic concentrations in two production wells in central and western Oklahoma that yield water from the Permian-aged Garber-Wellington and Rush Springs aquifers, respectively. In addition, well-head samples were collected from 12 production wells yielding water with historically large concentrations of arsenic (greater than 10 micrograms per liter) from the Garber-Wellington aquifer, Rush Springs aquifer, and two minor aquifers: the Arbuckle-Timbered Hills aquifer in southern Oklahoma and a Permian-aged undefined aquifer in north-central Oklahoma. Three depth-dependent samples from a production well in the Rush Springs aquifer had similar water-quality characteristics to the well-head sample and did not show any substantial changes with depth. However, slightly larger arsenic concentrations in the two deepest depth-dependent samples indicate the zones yielding noncompliant arsenic concentrations are below the shallowest sampled depth. Five depth-dependent samples from a production well in the Garber-Wellington aquifer showed increases in arsenic concentrations with depth. Well-bore travel-time information and water-quality data from depth-dependent and well-head samples showed that most arsenic contaminated water (about 63 percent) was entering the borehole from perforations adjacent to or below the shroud that overlaid the pump. Arsenic concentrations ranged from 10.4 to 124 micrograms per liter in 11 of the 12 production wells sampled at the well head, exceeding the maximum contaminant level of 10 micrograms per liter for drinking water. pH values of the 12 well-head samples ranged from 6.9 to 9. Seven production wells in the Garber-Wellington aquifer had the largest arsenic concentrations ranging from 18.5 to 124 micrograms per liter. Large arsenic concentrations (10.4-18.5) and near neutral to slightly alkaline pH values (6.9-7.4) were detected in samples from one well in the Garber-Wellington aquifer, three production wells in the Rush Springs aquifer, and one well in an undefined Permian-aged aquifer. All well-head samples were oxic and arsenate was the only species of arsenic in water from 10 of the 12 production wells sampled. Arsenite was measured above the laboratory reporting level in water from a production well in the Garber-Wellington aquifer and was the only arsenic species measured in water from the Arbuckle-Timbered Hills aquifer. Fluoride and uranium were the only trace elements, other than arsenic, that exceeded the maximum contaminant level for drinking water in well-head samples collected for the study. Uranium concentrations in four production wells in the Garber-Wellington aquifer ranged from 30.2 to 99 micrograms per liter exceeding the maximum contaminant level of 30 micrograms per liter for drinking water. Water from these four wells also had the largest arsenic concentrations measured in the study ranging from 30 to 124 micrograms

    Background. Despite, increasing number of percutaneous transluminal coronary angioplasty (PTCA) being performed, there is a paucity of Indian studies on the psychological effects of PTCA. Aim. To study the relation of anxiety, depression, and health related quality of life with outcome after PTCA. Methods. A total of 35 patients undergoing PTCA were included in the present project with their informed consent. All patients filled a specially designed proforma, the Hospital Anxiety and Depression Scale, Coronary Scale, Seattle Angina Questionnaire, and a health related quality of life measure (EQ 5D) one day before undergoing PTCA. Three days after PTCA patients were reassessed with the Hospital anxiety & depression scale, Seattle angina questionnaire and the EQ 5D. Results. Analysis showed that 46% had significant anxiety and 32.1% had significant depression before PTCA. Following successful PTCA, none of the patients had significant anxiety, and only 2 (3.6%) had significant depression. On the Seattle Angina Questionnaire, physical limitation reduced from 67.9 to 48. Disease perception improved from 21.2 to 37.1. On the EQ5D, the health status improved from 42.7 before PTCA to 78.7 after PTCA. Conclusion. Successful PTCA resulted in significant reduction in anxiety, depression, and physical limitation and improvement in disease perception and health status. PMID:24319368

    Disability-adjusted life expectancy is focused on more than just extending life span; thus, health-related quality of life (HRQOL) has emerged as an important issue for elderly patients with chronic disease. The number of patients with Parkinson's disease (PD) is predicted to grow along with the aging population, so it is essential to identify the predictors of HRQOL. This study utilized structural equation modeling (SEM) to predict the HRQOL of patients with PD. Participants (N = 217) were patients diagnosed with PD (M age = 66.01). Demographic and disease-related characteristics, sleep quality, pain, depression, and HRQOL were investigated via a structured questionnaire. Participants' functional factors were measured using physical function evaluations. The hypothetical model verified disease-related factors, depression, and pain as direct factors that significantly predicted HRQOL of patients with PD (Goodness of Fit Index = 0.93 and Comparative Fit Index = 0.96). These findings are useful for developing comprehensive interventions to improve the HRQOL of patients with PD. PMID:24718037

    We illustrate the way formal model identification criteria can be employed to provide analyses of laboratory-scale experiments of two-phase relative permeability curves by taking into account the uncertainty associated with mathematical formulation of the interpretive model. We do so by grounding our analysis on a set of empirical two-phase relative permeability models (i.e., Corey, Chierici and LET) which are typically employed in industrial applications requiring water/oil relative permeability quantifications. Our analysis is grounded on a dataset acquired through extensive experimental campaigns as well as published relative permeability curves. Bayesian and information theoretic criteria are applied to rank the alternative models selected and to assign a posterior probability weight to each of them. Our work shows that, in the most cases the complexity of the problem justifies favoring a model with a high number of uncertain parameters over a simpler model structure

    We consider the unrestricted problem of two mutually attracting rigid bodies, a uniform sphere (or a point mass) and an axially symmetric body. We present a global, geometric approach for finding all relative equilibria (stationary solutions) in this model, which was already studied by Kinoshita. We extend and generalize his results, showing that the equilibria solutions may be found by solving at most two non-linear, algebraic equations, assuming that the potential function of the symmetric rigid body is known explicitly. We demonstrate that there are three classes of the relative equilibria, which we call cylindrical, inclined coplanar and conic precessions, respectively. Moreover, we also show that in the case of conic precession, although the relative orbit is circular, the point mass and the mass centre of the body move in different parallel planes. This solution has not been known yet in the literature.

    The goal was to examine processes in socialization that might account for an observed relation between early socioeconomic status and later child behavior problems. A representative sample of 585 children (n = 51 from the lowest socioeconomic class) was followed from preschool to grade 3. Socioeconomic status assessed in preschool significantly predicted teacher-rated externalizing problems and peer-rated aggressive behavior in kindergarten and grades 1, 2, and 3. Socioeconomic status was significantly negatively correlated with 8 factors in the child's socialization and social context, including harsh discipline, lack of maternal warmth, exposure to aggressive adult models, maternal aggressive values, family life stressors, mother's lack of social support, peer group instability, and lack of cognitive stimulation. These factors, in turn, significantly predicted teacher-rated externalizing problems and peer-nominated aggression and accounted for over half of the total effect of socioeconomic status on these outcomes. These findings suggest that part of the effect of socioeconomic status on children's aggressive development may be mediated by status-related socializing experiences. PMID:8013245

    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

    2013-01-01

    Background Functional exercise capacity in people with asbestos related pleural disease (ARPD) is unknown and there are no data on health-related quality of life (HRQoL). The primary aims were to determine whether functional exercise capacity and HRQoL were reduced in people with ARPD. The secondary aim was to determine whether functional exercise capacity was related to peak exercise capacity, HRQoL, physical activity or respiratory function. Methods In participants with ARPD, exercise capacity was measured by the six-minute walk test (6MWT) and incremental cycle test (ICT); HRQoL by the St George’s Respiratory Questionnaire and physical activity by an activity monitor worn for one week. Participants also underwent lung function testing. Results 25 males completed the study with a mean (SD) age of 71 (6) years, FVC 82 (19)% predicted, FEV1/FVC 66 (11)%, TLC 80 (19)% predicted and DLCO 59 (13)% predicted. Participants had reduced exercise capacity demonstrated by six-minute walk distance (6MWD) of 76 (11)% predicted and peak work rate of 71 (21)% predicted. HRQoL was also reduced. The 6MWD correlated with peak work rate (r=0.58, p=0.002), St George’s Respiratory Questionnaire Total score (r=-0.57, p=0.003), metabolic equivalents from the activity monitor (r=0.45, p<0.05), and FVC % predicted (r=0.52, p<0.01). Conclusions People with ARPD have reduced exercise capacity and HRQoL. The 6MWT may be a useful surrogate measure of peak exercise capacity and physical activity levels in the absence of cardiopulmonary exercise testing and activity monitors.

    We obtained new periodic solutions in the problems of three and four point vortices moving on a plane. In the case of three vortices, the system is reduced to a Hamiltonian system with one degree of freedom, and it is integrable. In the case of four vortices, the order is reduced to two degrees of freedom, and the system is not integrable. We present relative and absolute choreographies of three and four vortices of the same intensity which are periodic motions of vortices in some rotating and fixed frame of reference, where all the vortices move along the same closed curve. Similar choreographies have been recently obtained by C. Moore, A. Chenciner, and C. Simo for the n-body problem in celestial mechanics [6, 7, 17]. Nevertheless, the choreographies that appear in vortex dynamics have a number of distinct features.

    Runaway youths represent a neglected clinical group, and few studies have examined ethnicity differences within this population. Substance use, family functioning and related problem behaviors were examined in a sample of Hispanic and Anglo runaway youths with substance abuse diagnoses (N = 145). Youths, aged 12–17, were recruited from two urban, southwestern runaway shelters. Within single-parent families, Anglo youths reported more marijuana use, and, regardless of family constitution, reported more tobacco use than did Hispanic youths. Overall, Anglo youths reported more externalizing problems and more conflict tactics used in resolving disagreements with their primary caretaker while Hispanic youths reported higher depression and familism scores. Given the differences found between Hispanic and Anglo youths, the findings argue that culturally sensitive interventions for runaway youths and families are warranted. PMID:18795144

    Background There is a higher prevalence of intellectual disability (ID) among homeless people than in the general population. However, little is known about the additional psychosocial problems faced by homeless people with ID. We describe the prevalence of ID in a cohort of homeless people in the Netherlands, and report relationships between ID and psychosocial problems in terms of psychological distress, substance (mis)use and dependence, as well as demographic characteristics in this cohort. Methods This cross-sectional study is part of a cohort study among homeless people in the four major cities of the Netherlands. Data were derived from 387 homeless people who were interviewed and screened for ID six months after the baseline measurement. Multivariate logistic regression analyses and ?2 tests were performed to analyze relationships between ID, psychosocial problems and demographic characteristics. Findings Of all cohort members, 29.5% had a suspected ID. Participants with a suspected ID had a higher mean age, were more likely to be male and to fall in the lowest category of education than participants without a suspected ID. Having a suspected ID was related to general psychological distress (OR ?=?1.56, p<0.05), somatization (OR ?=?1.84, p<0.01), depression (OR ?=?1.58, p<0.05) and substance dependence (OR ?=?1.88, p<0.05). No relationships were found between a suspected ID and anxiety, regular substance use, substance misuse and primary substance of use. Conclusion The prevalence of ID among Dutch homeless people is higher than in the general population, and is related to more psychosocial problems than among homeless people without ID. Homeless people with a suspected ID appear to be a vulnerable subgroup within the homeless population. This endorses the importance of the extra attention required for this subgroup. PMID:24465905

    Background Few studies have investigated the association between objectively measured traffic noise and health-related quality of life. However, as traffic noise has been associated with both cardiovascular disease and diabetes, and health-issues including sleeping problems, annoyance, and stress, it seems plausible that traffic noise is associated with health-related quality of life. Methods Between 1999 and 2002, a cohort of 38,964 Danes filled in the short form-36 (SF-36) questionnaire. Residential exposure to road traffic and railway noise was calculated for all historical addresses for 10 years preceding the SF-36, using the Nordic prediction method. Associations between noise exposure and SF-36 summary scales and the eight sub-scales were calculated using general linear models, adjusted for age, sex, socioeconomic status, and lifestyle. Results Models adjusted for age, sex and socioeconomic factors showed that a 10 dB higher road traffic noise 1 year preceding SF-36 assessment was associated with a 0.14 lower mental component summary (MCS) score (95% confidence interval (CI) -0.26, -0.01). However, further adjustment for lifestyle factors (smoking, alcohol, and waist circumference) attenuated the association: (-0.08 (95% CI: -0.20, 0.04)). Exposure to more than 55 dB of railway noise in the same time period was borderline significantly associated with lower MCS. The physical component summary was not associated with traffic noise. Conclusion The present study suggests a weak association between traffic noise exposure and the mental health component score of SF-36, which may operate through lifestyle. The magnitude of effect was, however, not clinically relevant. PMID:25768919

    Background: In recent decades, the incidence of spinal cord injuries has increased. In a systemic review on epidemiology of traumatic spinal cord injury in developing countries reported 25.5/million cases per year. Objectives: To assess the quality of life (QOL) of the veterans among Iran-Iraq war with chronic spinal cord injuries (SCI) and to evaluate long-term impressions of SCI on their quality of life. Patients and Methods: Fifty-two veterans, all male, with chronic spinal cord injury from Iran-Iraq war (1980-1988) were interviewed and examined. The mean age of veterans at the time of interview was 49.3 years (38 to 80 years). Veterans were assessed by using a 36-item short-form (SF-36), hospital anxiety and depression scale (HADS) and the Barthel index. The presence or absence of pressure sores and spasticity were documented as well. Results: The mean age of veterans at the time of study was 49.3 years. Pearson's correlation test showed that depression and anxiety have a reverse association with mental component summary (MCS) scale and physical component summary (PCS) scale scores, respectively. Regression analysis showed a negative effect of depression and pressure sore on PCS. Moreover, no association was found between the duration of injury and age with quality of life. Conclusions: Lower QOL was found among veterans with chronic SCI. More researches on health-related quality of life (HRQOL) are needed to give us a better understanding of changes in life of patients with SCI and the ways to improve them. PMID:25147777

    The importance of health-related quality of life (HRQOL) continues to grow, as clinicians and clinical researchers have recognized the impact of the functional gastrointestinal disorders. Limited information is available on the performance of HRQOL questionnaires in Asia. Furthermore, the effect across different cultural settings of functional gastrointestinal disorders on HRQOL has been little studied in Eastern countries. We summarized recent studies on HRQOL in Korean patients with functional gastrointestinal disorders as well as other Asian literatures. Functional gastrointestinal disorders-related symptoms had a great effect on the HRQOL of Korean patients. These results and their considerable prevalence in Korea indicate that functional gastrointestinal disorders have a substantial social impact in this country. PMID:21860816

    Economic crises are complex events that affect behavioral patterns (including alcohol consumption) via opposing mechanisms. With this realist systematic review, we aimed to investigate evidence from studies of previous or ongoing crises on which mechanisms (How?) play a role among which individuals (Whom?). Such evidence would help understand and predict the potential impact of economic crises on alcohol consumption. Medical, psychological, social, and economic databases were used to search for peer-reviewed qualitative or quantitative empirical evidence (published January 1, 1990-May 1, 2014) linking economic crises or stressors with alcohol consumption and alcohol-related health problems. We included 35 papers, based on defined selection criteria. From these papers, we extracted evidence on mechanism(s), determinant, outcome, country-level context, and individual context. We found 16 studies that reported evidence completely covering two behavioral mechanisms by which economic crises can influence alcohol consumption and alcohol-related health problems. The first mechanism suggests that psychological distress triggered by unemployment and income reductions can increase drinking problems. The second mechanism suggests that due to tighter budget constraints, less money is spent on alcoholic beverages. Across many countries, the psychological distress mechanism was observed mainly in men. The tighter budget constraints mechanism seems to play a role in all population subgroups across all countries. For the other three mechanisms (i.e., deterioration in the social situation, fear of losing one's job, and increased non-working time), empirical evidence was scarce or absent, or had small to moderate coverage. This was also the case for important influential contextual factors described in our initial theoretical framework. This realist systematic review suggests that among men (but not among women), the net impact of economic crises will be an increase in harmful drinking. Such a different net impact between men and women could potentially contribute to growing gender-related health inequalities during a crisis. PMID:25771482

    Variability within the literature investigating typically-developing siblings of children with an autism spectrum disorder suggests that the quality of sibling outcomes may depend on specific factors. For this study, 42 parents of a child with an autism spectrum disorder and a typically- developing sibling provided data via online questionnaires. Birth order rank of the child with an autism spectrum disorder significantly moderated the relation between externalizing behaviors in children with an autism spectrum disorder and externalizing behaviors in their typically-developing siblings. Children with an autism spectrum disorder and higher levels of behavior problems had typically-developing siblings with higher levels of behavior problems only when the child with an autism spectrum disorder was older. These results provide a hint of clarification about the complex nature of sibling relations, but a great deal more research is needed to further examine outcomes of typically-developing siblings of children with an autism spectrum disorder.

    Abstract Background and Objectives: Identify the factors affecting quality of life (QOL) is one of the major goals for improving the Health Related Quality Of Life (HR-QOL) in patients suffering from Congestive Heart Failure (CHF). Considering the fact that there are few published studies in this regard in Iran, as a developing country, this research was designed to determine the HR-QOL in Iranian CHF patients and its related factors. Methods and Materials: In this cross-sectional study, random sampling was used to select 1840 female CHF patients. After obtaining informed consent, patients' demographic and disease-related data (using a researcher-made questionnaire which assessed eight dimensions including role-physical, physical functioning, bodily pain, general health, vitality, role-emotional, social functioning and mental health), and the HR-QOL data (using the SF-36 questionnaire) were assessed and analyzed with SPSS version 15. Results: A high proportion of the participants had an unfavorable HR-QOL in physical functioning (44.56%), role-physical (49.55%), role-emotional (59.83%), mental health (54.50%), and general health (53.36%) dimensions and a relatively favorable HR-QOL in social functioning (50.57%), vitality (49.26%), and body pain dimensions (52.55%). A significant relationship was found between the HR-QOL and the employment status, level of education, being cared for at home, functional capacity, disease duration, frequency of medical encounter and hospitalization, duration of hypertension and concurrent CHF, presence of edema, presence of disease symptoms and morbidities, intensity of fatigue at the study time and previous months, and the type of medications. Conclusion: According to the results, QOL in CHF patients was unfavorable in the scales of general health, role-emotional, and mental health. PMID:24708307

    In this study, similarities and differences in sibling relationships between children who have experienced family transitions and those who have not are examined. Comparisons are made between children who live in intact families, those whose parents have separated, and those who live in substitute care regarding the quality of their relationships with one of their siblings. More specifically, 4 dimensions describing the quality of sibling relationships are compared: Warmth/Closeness, Conflict, Relative Status/Power, and Rivalry (Furman & Buhrmester, 1985). The sample is made up of 3 groups of children (N = 158) aged between 8 and 12 years old: children living in intact families (n = 101), children who have experienced parental separation (n = 35), and children living in substitute care (n = 22). Results indicate differences on dimensions of Warmth/Closeness, Conflict, and Relative Status/Power. Different patterns of responses between the children who have experienced family transitions and those who have not are observed for the dimensions of Conflict and Power. The significant difference observed between the groups for the dimension of Warmth appears difficult to explain. Discussion of these results emphasizes the importance of the relationship between brothers and sisters experiencing family transition. PMID:14664110

    Objective. To investigate the voice-related quality of life in a group of patients with multiple sclerosis. Participants. A total of 87 subjects (59 MS subjects and 28 controls) participated in this study. Main Outcome Measures. Variables included presence or absence of phonatory symptoms, duration of the disease, the expanded disability status scale (EDSS), the severity of fatigue, and depression. All patients were asked to fill the Voice Handicap Index. Results. The average age was 35.47 years + 10.92 with 39% being males. The average duration of the disease was 77.93 months. The EDSS score was 1.94 + 1.84, the FSS score was 4.07 + 2.09, and the HRSD was 7.28 + 7.70. Only 7 subjects out of the 59 had vocal symptoms compared to 3 in the control group. There was no significant difference in the VHI total score between cases (5.9 + 15.5) and controls (5.4 + 8.2). There was a positive correlation between VHI total score, FSS score, and HRSD (P values of 0.011 and <0.01. Conclusion. The voice-related quality of life in MS is within normal with no disability.

    The aim of this study was to explore the health-related quality of life (HRQOL) of preschool caregivers in Hong Kong with a view to informing policy-makers about health promotion within this population. The following research questions were addressed: (i) What was the HRQOL of young children's caregivers in Hong Kong? (ii) Were there differences between these caregivers' health and the general Hong Kong population's health? (iii) What demographic factors were related to these caregivers' quality of life? Mixed methods research, including quantitative and qualitative tools, was utilized. Data from a study consisted of a survey of 834 preschool caregivers along with 3 in-depth interviews with employees of kindergarten-cum-childcare centres from different socio-economic groups within the city of Hong Kong. An HRQOL questionnaire (the SF-36 v. 1), together with demographic characteristics and illness/disease incidence data, were collected. The results suggested that the Hong Kong preschool caregivers had a substantially poorer HRQOL than Hong Kong's general population. The analysis found that young caregivers and caregivers with young families had a significantly lower HRQOL than more senior caregivers. They tended to feel tired, lacked energy and failed to perform vigorous activities. Significant differences were also found according to the caregivers' socio-economic status. Health and education policy-makers should note that young children's caregivers are in a serious state of ill health. Further health education and promotion efforts should target this population.

    Background: The Iran-Iraq war during the 1980-1988 has left many consequences on veterans and their families that persist long after the war ended. Objectives: The aim of this study was to evaluate the impact of psychological problems and marital adjustment of Iranian veterans on their children's quality of life and happiness 24 years after the war ended. Patients and Methods: The sample was all children of veterans in Isfahan city that registered by Veterans and Martyrs Affair Foundation (VMAF). One hundred sixty-three veterans were selected by systematic randomized sampling and the symptom checklist-90-revised (SCL-90-R) and dyadic adjustment scale (DAS) were administered for them. Their wives filled out the DAS and their children answered to World Health Organization Quality of Life-Brief version (WHOQOL-BREF) and Oxford Happiness Inventory (OHI). The data from questionnaires completed by 149 families were analyzed using the multiple regressions analysis. Results: Global Severity Index (GSI) scores of veterans and veteran's age were inversely correlated with the scores of children's quality of life, while marital adjustment of parents and number of rooms in house were positively correlated. Mother's age was inversely correlated with the scores of children's happiness, while marital adjustment of the parents, the number of rooms in their house and the number of children were positively correlated. Conclusions: In veterans' family, psychological health of the veterans and marital adjustment of the parents have a significant relationship with their children's quality of life and happiness.

    Background: Breast cancer is the most common cancer among women and 81% of therapeutic surgery performed for breast cancer in Iran is mastectomy. Following mastectomy, the patients suffer from many problems which lead to several disorders and decrease in their quality of life (QOL). Materials and Methods: This cross-sectional descriptive study was conducted on 105 breast cancer patients who underwent mastectomy, selected with a convenient sampling method. A questionnaire containing three parts was used to collect data. The data were analyzed by SPSS version 14 using descriptive and analytical statistical methods. Results: Spearman test showed that there was a statistically significant relationship between QOL and education level and also fatigue. Moreover, Spearman test indicated a statistically significant correlation between age and the mental dimension of QOL. There was no significant relationship between QOL with marital and employment status. Conclusions: Based on the findings, we can suggest that nurses should be educated about the factors affecting QOL. They can receive the necessary knowledge in various areas such as meeting the patients, optimum management of patients’ problems, improvement of their health, and finally help to increase the cancer patients’ QOL.

    Background This study aimed to determine the prevalence of anxiety among prostate cancer patients, and to ascertain the association between stress status, socio-demographic, medical and surgical illness, current urinary problem and cancer status with general health-related quality of life (HRQOL) among these patients. Methods: A hospital based, cross sectional study was conducted at Surgical Clinic, University Malaya Medical Centre (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) using universal sampling. Result: A total of 193 patients were recruited. The prevalence of anxiety was 25.4% (95%CI: 19.2 – 31.6). The anxiety ratings were mild anxiety (10.4%), moderate anxiety (13.6%) and severe anxiety (1.6%). The total quality of life among stress group was 59.2 ± 14.7 and among non-stress group was 73.9 ± 12.7. There was a significant negative weak correlation between anxiety score and total quality of life (rs=?0.534, P<0.001). In multivariable analysis, there was a significant difference in the total quality of life (QOL) among anxiety status [adj. mean diff. = ?9.1 (95%CI: ?15.2, ?4.7)]. The adjusted mean difference was associated by age category of the patients (P<0.001); living partner (P<0.001); intermittency (P=0.035) and problem of hematuria during micturition (P=0.005). Conclusion: The prevalence of anxiety among prostate cancer was moderately high. Treating the urination problem as well as encouraging living with spouse/family may improve the quality of life among anxiety condition of these patients. PMID:23641401

    This article reports an investigation of some of the skills needed for the critical reading of physics texts. To assess these skills a reading comprehension test was developed that combines features of errordetection and true-false-unreported tests. This test was administered to college students of physics, and the results were analyzed statistically to determine the separability of the skills and their hierarchical ranking. It was found that the skill required to comprehend texts in continuous format is of a higher level than and separable from the skill required to comprehend texts in the form of a separated list of statements. The skill required to discriminate unreported statements from the others (true and false) was found to be of a higher level than and separable from the skills required to make the other discriminations. The relation between the students' reading comprehension skills and their problem-solving ability was also investigated. Students' scores on reading comprehension of texts that require a very low problem-solving ability were found to be uncorrelated to their grades on solving problems that require a very low decoding ability. This implies that the two abilities are independent.Received: 31 August 1993; Revised: 27 July 1994;

    Viewing the role of technology as either the cause of or solution to environmental problems may be unrealistic, and such extreme attitudes may inhibit the resolution of environmental problems. Courses that present a particular orientation toward the role of technology may encourage these extreme attitudes. Identifying attitudes of students enrolled in such courses and designing instruction to foster specific attitudes can lead to a more rational and objective attitude toward technology as related to environmental problems. The Scientific-Environmental-Technological (SET) literacy model was suggested as an appropriate framework for presenting the role of technology to students. A 34 item Likert scale was developed to measure attitudes as defined by two constructs: PRO-technology and ANTI-technology. Students enrolled in three courses (E200, Environment and People, K201, The Computer in Business, E100, Freshman Engineering Lectures), were asked to respond to the survey at the beginning and end of the fall, 1980 semester. The findings indicate that the survey was useful in identifying and characterizing attitudes of certain populations. The differences between the E200 and E100 students indicate that instruction that recognizes and examines the full range of perspectives on the impact of technology should be provided for these students.

    The NATO Advanced Research Workshop on Nuclear Submarine Decommissioning and Related Problems was held in Moscow June 19--22, 1995. It was preceded by a visit to the Zvezdotchka Shipyard at Severodvinsk, a repair and maintenance yard for Russian nuclear submarines, for a subgroup of the workshop attendees. Most of the material in this paper is drawn directly form the workshop proceedings. Slightly less than 500 nuclear ships and submarines (the vast majority are submarines) have been constructed by the countries with nuclear navies. This includes approximately 250 by Russia, 195 by the United States, 23 by the United Kingdom, 11 by France and 6 by China. By the year 2000 it is expected that approximately one-half of these nuclear vessels will be removed from service and in various states of decommissioning. A newspaper account in June 1997 indicated that 156 Russian nuclear submarines had been removed from service. In August 1996 it was reported that 55 reactor compartment sections from US nuclear submarines were already in long-term storage at Hanford. Overall the dismantlement of nuclear submarines and the processing, storage and disposal of nuclear fuel, activated components and section of the hulls, and the liquid and solid radioactive and hazardous wastes is an enormous problem. This problem has been exacerbated by the accelerated decommissioning schedule associated with treaty obligations.

    In Finland, a dental subsidization reform, implemented in 2001-2002, abolished age restrictions on subsidized dental care. We investigated income-related inequality in oral health-related quality of life (OHRQoL) and its determinants among adult Finns before and after the reform. Three cross-sectional postal surveys, focusing on perceived oral health and the use of dental services among people born before 1971, were conducted in 2001 (n = 2,046), 2004 (n = 1,728), and 2007 (n = 1,560). Five measures, based on the Oral Health Impact Profile-14, were used as indicators of OHRQoL. Income-related inequality and associated factors were analysed using the concentration index and its decomposition. Prevalence, extent, and severity of oral health impacts were slightly lower in 2007 than in 2001. The oral health impacts were concentrated, at all study time points, among individuals with lower income. Most of the inequality was related to self-perceived general health, tooth loss, and income. Contributions of time since the last dental visit and satisfaction with the last treatment period to the inequality decreased from 2001 to 2007. However, the contributions of these factors were already small (10-20%) in 2001. In general, OHRQoL improved slightly; however, no clear or dramatic change in inequality in OHRQoL was seen after the reform. PMID:26015152

They are involved in many aspects of the host life, physiology and evolution, including nutrition, reproduction, immune homeostasis, defence and speciation. Thus, the manipulation and the exploitation the microbiota could result in important practical applications for the development of strategies for the management of insect-related problems. This approach, defined as 'Microbial Resource Management' (MRM), has been applied successfully in various environments and ecosystems, as wastewater treatments, prebiotics in humans, anaerobic digestion and so on. MRM foresees the proper management of the microbial resource present in a given ecosystem in order to solve practical problems through the use of microorganisms. In this review we present an interesting field for application for MRM concept, i.e. the microbial communities associated with arthropods and nematodes. Several examples related to this field of applications are presented. Insect microbiota can be manipulated: (i) to control insect pests for agriculture; (ii) to control pathogens transmitted by insects to humans, animals and plants; (iii) to protect beneficial insects from diseases and stresses. Besides, we prospect further studies aimed to verify, improve and apply MRM by using the insect-symbiont ecosystem as a model. PMID:22103294

    Purpose:A genetic diagnosis is an extremely useful tool in the management and care of families with inherited heart diseases, particularly in allowing clarification of risk status of asymptomatic family members. The psychosocial consequences of genetic testing in this group are poorly understood. This longitudinal pilot study sought to determine changes in health-related quality of life in patients and asymptomatic family members undergoing genetic testing for inherited heart diseases.Methods:Individuals attending two specialized multidisciplinary cardiac genetic clinics in Australia were invited to participate. Patients undergoing proband or predictive genetic testing for an inherited cardiomyopathy or primary arrhythmogenic disorder were eligible. The Medical Outcomes Short Form-36 (version 2) was administered before the genetic result was given, and follow-up surveys were completed 1-3, 6, and 12 months after the result was given.Results:A total of 54 individuals with hypertrophic cardiomyopathy, familial dilated cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, and long QT syndrome completed baseline and at least one follow-up survey, including 33 probands and 21 asymptomatic relatives. Physical and mental component scores analyzed at baseline and 1-3 months were found to be unchanged in all groups. Furthermore, no significant differences were observed up to 12 months after result.Conclusion:In this longitudinal pilot study, no change in health-related quality of life was observed up to 12 months after the result was given in patients and their asymptomatic family members undergoing genetic testing for an inherited heart disease.Genet Med 2012 advance online publication 3 May 2012.

    Rhegmatenous retinal detachment (RRD) is one of the most serious complications after phacoemulsification combined with intraocular lens implantation surgery. It has been reported that vision-related quality of life (VRQoL), as well as visual acuity rapidly decreased when RRD developed. However, little is known of the VRQoL in those RRD patients after anatomical retinal re-attachment, especially whether or not the VRQoL is higher than that before cataract surgery. In this prospective case series study, we use the Chinese-version low vision quality of life questionnaire (CLVQOL) to assess the changes of VRQoL in age-related cataract patients who suffered from RRD after phacoemulsification with intraocular lens (phaco-IOL) implantation. All participants were asked to complete questionnaires in face- to-face interviews one day before and two weeks after cataract surgery, as well as one day before and three months after RRD surgery. A total of 10,127 consecutive age-related cataract patients were followed up to one year after phaco-IOL implantation; among these patients, 17 were diagnosed as RRD. The total CLVQOL scores and subscale scores except “Mobility” decreased significantly when RRD developed. After retinal surgery, only the score of “General vision and lighting” in the CLVQOL questionnaires improved when compared to the scores two weeks after cataract surgery, although the best corrected visual acuity of all patients significantly raised up. However, the mean CLVQOL scores and subscale scores were still considerably higher than the level prior to cataract surgery. Our study suggests that cataract patients at high risk of postoperative RRD should not deny the opportunity to undergo phaco-IOL implantation, even though potential VRQoL impairment induced by RRD exists.

    Objective: Impulsivity is associated with increased marijuana use and subsequent marijuana-related problems among marijuana users. In addition, single nucleotide polymorphisms (SNPs) in the cannabinoid receptor 1 (CNR1) and fatty acid amide hydrolase (FAAH) genes have been associated with cannabis-related phenotypes. This exploratory study tested whether the association between different aspects of impulsivity and the number of marijuana-related problems among users is explicated by variation in these putative cannabinoid-related genes. Method: A total of 151 young adult regular marijuana users (used on M = 41.4% of the prior 60 days, SD = 24.3%) provided DNA and completed measures of trait (Barratt Impulsiveness Scale) and behavioral impulsivity (Stop Signal Task and Delay Discounting Questionnaire), as well as a self-report of marijuana-related problems. Three CNR1 and five FAAH SNPs were genotyped, tested for haplotype blocks, and subsequently examined for association with phenotypes described above. Results: CNR1 variation significantly moderated the association between trait-level, but not behavioral, impulsivity and marijuana-related problems, such that the combination of higher trait impulsivity and CNR1 variation was associated with a greater number of marijuana-related problems. In contrast, there were no significant FAAH by impulsivity interactions; however, there was a main effect of FAAH on marijuana-related problems. Conclusions: These findings support an association with CNR1 and FAAH genes and marijuana-related problems among regular marijuana users. CNR1 variation emerged as a moderator of the relationship between trait impulsivity and marijuana problems, thus suggesting that marijuana users with CNR1 risk variants and a higher trait impulsivity are at greater risk for developing marijuana-related problems and supporting a role for CNR1 in a broader impulsivity phenotype.
