Pregaming is a high-risk drinking behavior associated with increased alcohol consumption and alcohol-related problems. Quantity of alcohol consumed does not fully explain the level of problems associated with pregaming; yet, limited research has examined factors that may interact with pregaming behavior to contribute to the experience of alcohol-related problems. The current study examined whether use of two emotion regulation strategies influence pregaming's contribution to alcohol-related problems. Undergraduates (N = 1857) aged 18-25 years attending 19 different colleges completed an online survey in 2008-2009. Linear mixed models were used to test whether emotion regulation strategies moderate the association between pregaming status (pregamers vs. non/infrequent pregamers) and alcohol-related problems, when controlling for alcohol consumption, demographic covariates, and site as a random effect. Greater use of cognitive reappraisal was associated with decreased alcohol problems. Expressive suppression interacted with pregaming status. There was no relationship between pregaming status and alcohol problems for students who rarely used expression suppression; however, the relationship between pregaming status and alcohol problems was statistically significant for students who occasionally to frequently used expression suppression. Findings suggest that the relationship between pregaming and alcohol-related problems is complex. Accordingly, future studies should utilize event-level methodology to understand how emotion regulation strategies influence alcohol-related problems. Further, clinicians should tailor alcohol treatments to help students increase their use of cognitive reappraisal and decrease their use of suppression.

Associations between owner personality and psychological status and the prevalence of canine behavior problems

Dodman, Nicholas H.; Brown, Dorothy C.

2018-01-01

Behavioral problems are a major source of poor welfare and premature mortality in companion dogs. Previous studies have demonstrated associations between owners’ personality and psychological status and the prevalence and/or severity of their dogs’ behavior problems. However, the mechanisms responsible for these associations are currently unknown. Other studies have detected links between the tendency of dogs to display behavior problems and their owners’ use of aversive or confrontational training methods. This raises the possibility that the effects of owner personality and psychological status on dog behavior are mediated via their influence on the owner’s choice of training methods. We investigated this hypothesis in a self-selected, convenience sample of 1564 current dog owners using an online battery of questionnaires designed to measure, respectively, owner personality, depression, emotion regulation, use of aversive/confrontational training methods, and owner-reported dog behavior. Multivariate linear and logistic regression analyses identified modest, positive associations between owners’ use of aversive/confrontational training methods and the prevalence/severity of the following dog behavior problems: owner-directed aggression, stranger-directed aggression, separation problems, chasing, persistent barking, and house-soiling (urination and defecation when left alone). The regression models also detected modest associations between owners’ low scores on four of the ‘Big Five’ personality dimensions (Agreeableness, Emotional Stability, Extraversion & Conscientiousness) and their dogs’ tendency to display higher rates of owner-directed aggression, stranger-directed fear, and/or urination when left alone. The study found only weak evidence to support the hypothesis that these relationships between owner personality and dog behavior were mediated via the owners’ use of punitive training methods, but it did detect a more than five-fold increase in the use of aversive/confrontational training techniques among men with moderate depression. Further research is needed to clarify the causal relationship between owner personality and psychological status and the behavioral problems of companion dogs. PMID:29444154

Will cognitive enhancement create post-persons? The use(lessness) of induction in determining the likelihood of moral status enhancement.

PubMed

Mihailov, Emilian; Dragomir, Alexandru

2018-06-01

The prospect of cognitive enhancement well beyond current human capacities raises worries that the fundamental equality in moral status of human beings could be undermined. Cognitive enhancement might create beings with moral status higher than persons. Yet, there is an expressibility problem of spelling out what the higher threshold in cognitive capacity would be like. Nicholas Agar has put forward the bold claim that we can show by means of inductive reasoning that indefinite cognitive enhancement will probably mark a difference in moral status. The hope is that induction can determine the plausibility of post-personhood existence in the absence of an account of what the higher status would be like. In this article, we argue that Agar's argument fails and, more generally, that inductive reasoning has little bearing on assessing the likelihood of post-personhood in the absence of an account of higher status. We conclude that induction cannot bypass the expressibility problem about post-persons. © 2018 John Wiley & Sons Ltd.

Socioeconomic status, parenting, and externalizing problems in African American single-mother homes: A person-oriented approach.

PubMed

Anton, Margaret T; Jones, Deborah J; Youngstrom, Eric A

2015-06-01

African American youth, particularly those from single-mother homes, are overrepresented in statistics on externalizing problems. The family is a central context in which to understand externalizing problems; however, reliance on variable-oriented approaches to the study of parenting, which originate from work with intact, middle-income, European American families, may obscure important information regarding variability in parenting styles among African American single mothers, and in turn, variability in youth outcomes as well. The current study demonstrated that within African American single-mother families: (a) a person-, rather than variable-, oriented approach to measuring parenting style may further elucidate variability; (b) socioeconomic status may provide 1 context within which to understanding variability in parenting style; and (c) 1 marker of socioeconomic status, income, and parenting style may each explain variability in youth externalizing problems; however, the interaction between income and parenting style was not significant. Findings have potential implications for better understanding the specific contexts in which externalizing problems may be most likely to occur within this at-risk and underserved group.

The interplay among socioeconomic status, household chaos, and parenting in the prediction of child conduct problems and callous-unemotional behaviors.

PubMed

Mills-Koonce, W Roger; Willoughby, Michael T; Garrett-Peters, Patricia; Wagner, Nicholas; Vernon-Feagans, Lynne

2016-08-01

Child conduct problems (CP) reflect a heterogeneous collection of oppositional, aggressive, norm-violating, and sometimes violent behaviors, whereas child callous-unemotional (CU) behaviors reflect interpersonal styles of interactions reflecting a lack of guilt and empathy as well as uncaring and shallow emotional responses to others. Taken together, high levels of child CP and CU behaviors are thought to identify a relatively homogenous group of children at elevated risk for persistent and more severe problem behaviors across childhood and into adulthood. Although a large body of research has examined the developmental etiology of CP behaviors, only recently has a developmental psychopathology approach been applied to early CU behaviors. The current study examines multiple levels of contextual influences during the first years of life, including family socioeconomic status, household chaos, and parenting behaviors, on CP and CU behaviors assessed during the first-grade year. Whereas previous studies found associations between parenting behaviors and child problem behaviors moderated by household chaos, the current study found no evidence of moderation. However, path analyses suggest that the associations between child CP and CU behaviors and the contextual variables of socioeconomic status (family income and parental education) and household chaos (disorganization and instability) were mediated by maternal sensitive and harsh-intrusive parenting behavior. Analyses are presented, interpreted, and discussed with respect to both bioecological and family stress models of development.

Late-adoptions in adolescence: Can attachment and emotion regulation influence behaviour problems? A controlled study using a moderation approach.

PubMed

Pace, Cecilia Serena; Di Folco, Simona; Guerriero, Viviana

2018-03-01

A growing body of research suggests that, compared to normative adolescence, adoptive adolescence could be considered a specific risk condition characterized by more psychiatric problems, attachment insecurity, and emotional regulation difficulties as consequences of negative experiences in preadoption relationships. The current study explores (a) a moderation model of adoption status on the association between attachment representations (secure, dismissing, preoccupied, and disorganized) and behavioural problems and (b) a moderation model of adoption status on the association between emotion regulation processes (cognitive reappraisal and expressive suppression) and behavioural problems. Both the moderation models were controlled for verbal skills. Forty-six adopted adolescents and a control group of 34 nonadopted peers (12-16 years old) living with both their biological parents were assessed using the Friends and Family Interview, the Emotion Regulation Questionnaire for Children and Adolescents, the Child Behaviour Check List 6-18, and the verbal subtests of the Wechsler Intelligence Scale for Children, the latter as control measure. Results showed that adoption status (but not attachment) positively predicted externalizing and total behaviour problems, whereas attachment disorganization (but not adoption status) positively predicted internalizing problems in both group. Moreover, low cognitive reappraisal had a negative impact on externalizing problems only for adopted adolescents, but not for nonadopted youths. The clinical implications of these findings are discussed in order to enhance effective intervention with adopted adolescents and their parents. Copyright © 2017 John Wiley & Sons, Ltd.

2011-03-01

Relatively few studies have examined gambling problems among individuals in a casino setting. The current study sought to examine the prevalence of gambling problems among a sample of casino patrons and examine alcohol and tobacco use, health status, and quality of life by gambling problem status. To these ends, 176 casino patrons were recruited by going to a Southern California casino and requesting that they complete an anonymous survey. Results indicated the following lifetime rates for at-risk, problem, and pathological gambling: 29.2, 10.7, and 29.8%. Differences were found with regards to gambling behavior, and results indicated higher rates of smoking among individuals with gambling problems, but not higher rates of alcohol use. Self-rated quality of life was lower among pathological gamblers relative to non-problem gamblers, but did not differ from at-risk or problem gamblers. Although subject to some limitations, our data support the notion of higher frequency of gambling problems among casino patrons and may suggest the need for increased interventions for gambling problems on-site at casinos.

We evaluated the association between residential exposure to outdoor alcohol advertising and current problem drinking among 139 African American women aged 21 to 49 years in Central Harlem, New York City. We found that exposure to advertisements was positively related to problem drinking (13% greater odds), even after we controlled for a family history of alcohol problems and socioeconomic status. The results suggest that the density of alcohol advertisements in predominantly African American neighborhoods may add to problem drinking behavior of their residents.

Economic hardships in adulthood and mental health in Sweden. The Swedish National Public Health Survey 2009.

Possible accumulative effects of a combined economic hardship's measure, including both income and non-income related economic hardships measures, on mental health has not been well investigated. The aim of this paper was to investigate; (i) independent associations between multiple measures of economic hardships and mental health problems, and (ii) associations between a combined economic hardships measure and mental health problems. We analysed data from the 2009 Swedish National Survey of Public Health comprising a randomly selected representative national sample combined with a randomly selected supplementary sample from four county councils and three municipalities consisting of 23,153 men and 28,261 women aged 16-84 years. Mental health problems included; psychological distress (GHQ-12), severe anxiety and use of antidepressant medication. Economic hardship was measured by a combined economic hardships measure including low household income, inability to meet expenses and lacking cash reserves. The results from multivariate adjusted (age, country of birth, educational level, occupational status, employment status, family status and long term illness) logistic regression analysis indicate that self-reported current economic difficulties (inability to pay for ordinary bills and lack of cash reserves), were significantly associated with both women's and men's mental health problems (all indicators), while low income was not. In addition, we found a statistically significant graded association between mental health problems and levels of economic hardships. The findings indicate that indicators of self-reported current economic difficulties seem to be more strongly associated with poor mental health outcomes than the more conventional measure low income. Furthermore, the likelihood of mental health problems differed significantly in a graded fashion in relation to levels of economic hardships.

Some problems in the A. roxburghii industry were revealed and a variety of sustainable development countermeasures were also proposed. The main problems of A. roxburghii industry are the lack of protection for wild resources, the lag in the speed of variety breeding, the insufficient research on the quality systems, the low level of industry and product innovation capability, as well as the relatively low market cognition and brand competence. Therefore, strengthening the protection for breeding resources, establishing a dynamic monitoring system, promoting the variety breeding, constructing a propagation system for improved varieties, enhancing the quality of medicinal herbs, accelerating the adjustment of product structure, upgrading the industry technology, strengthening brand competence and expanding the market, will be the effective methods to realize the sustainable development of A. roxburghii industry.

A growing population of youth who acquired HIV from their mothers are surviving into adulthood. This group is unique in that they experience both internalized stigma (due to their HIV status) and associative stigma (due to their mothers' HIV status). Results of a cross-sectional survey of 250 perinatally HIV-infected South African youth suggests that internalized stigma is associated with greater risk of depression, and associative stigma is associated with greater risk of depression and substance use problems. Interventions currently focus on internalized stigma; this study highlights the importance of also addressing associative stigma to improve outcomes among perinatally HIV-infected youth.

Long-term social status and intimate relationship in women with childhood sexual abuse who got outpatient psychotherapy for anxiety disorder and depression.

The aim of this paper was twofold: namely to examine current intimate relationships and social status of women with childhood sexual abuse (CSA) in the long term after outpatient psychotherapy, and to investigate the relative influence of CSA and family background risk factors (FBRF) on the indicators of this status. Fifty-six women with reported CSA and 56 without CSA, who had outpatient psychotherapy for anxiety disorders and/or depression, were personally examined 5 years after termination. Women with CSA had considerably greater sexual and mental health problems, but the same prevalence of partnerships, children and friends as the contrast. No differences were observed as to self-esteem, intimate bonds and physical quality of life. Sexual problems and low education were mainly explained by CSA, other measures by FBRF. Women treated with outpatient psychotherapy for anxiety disorders and depression had moderate problems at long-term follow-up, but more so for those women who had been exposed to CSA.

Executive functioning (EF) problems may serve as vulnerability or maintenance factors for Binge-Eating Disorder (BED). However, it is unclear if EF problems observed in BED are related to overweight status or BED status. The current study extends this literature by examining EF in overweight and normal-weight BED compared to weight-matched controls. Participants were normal-weight women with BED (n = 23), overweight BED (n = 32), overweight healthy controls (n = 48), and normal-weight healthy controls (n = 29). The EF battery utilized tests from the National Institutes of Health (NIH) Toolbox and Delis-Kaplan Executive Function System (D-KEFS). After controlling for years of education and minority status, overweight individuals performed more poorly than normal-weight individuals on a task of cognitive flexibility requiring generativity (p < .01), and speed on psychomotor performance tasks (p = .01). Normal-weight and overweight BED performed worse on working memory tasks compared to controls (p = .04). Unexpectedly, normal-weight BED individuals out-performed all other groups on an inhibitory control task (p < .01). No significant differences were found between the four groups on tasks of planning. Regardless of weight status, BED is associated with working memory problems. Replication of the finding that normal-weight BED is associated with enhanced inhibitory control is needed. © 2017 Wiley Periodicals, Inc.

Neurodegenerative diseases constitute a major problem of public health that is associated with an increased risk of mortality and poor quality of life. Malnutrition is considered as a major problem that worsens the prognosis of patients suffering from neurodegenerative diseases. In this aspect, the present review is aimed to critically collect and summarize all the available existing clinical data regarding the clinical impact of nutritional assessment in neurodegenerative diseases, highlighting on the crucial role of nutritional status in disease progression and management. According to the currently available clinical data, the nutritional status of patients seems to play a very important role in the development and progression of neurodegenerative diseases. A correct nutritional evaluation of neurodegenerative disease patients and a right nutrition intervention is essential in monitoring their disease.

To assess the prevalence and correlates of current smoking, awareness of hazards, and quitting behavior among smokers 30 years and above. Cross-sectional; Gokulpuri, a resettlement colony in East Delhi, India; 911, persons aged 30 years and above using systematic random sampling; Study tools: Semi-structured questionnaire. Prevalence of current smoking was found to be 24.6% (95% CI 21.90 - 27.49). Majority 198 (88.4%) of current smokers smoked bidi exclusively, and on an average 13.5 bidi/cigarette were smoked per day. Multivariate analysis showed the factors associated with current smoking as male sex, advancing age, illiteracy, skilled occupation, low socio-economic status, and low BMI (P < 0.001). 64.2% were aware of the hazards of smoking. 63 (21.9%) had quit smoking in the past, majority due to the health problems. Low educational status was associated with poor hazard awareness and quitting behavior. Smoking is a significant problem among poor and illiterate males, shows an increasing trend with an advancing age and is directly associated with skilled occupation and low BMI. There are significant gaps in knowledge regarding hazards of smoking.

Forcing with the population growth and consequently increasing food requirement, food security in sub-Saharan Africa is one of the most emergent and challenging issues. The purposes of this work are 1) what's the future food requirement and their food security status in each sub-Saharan African countries? What is the distance from current and future food security status, corresponding to the food requirement, to the targeted food security status? 2) To what extent Sub-Saharan countries could meet their present and future food requirement, and whether they have potential to improve their food insecurity status on currently cultivated land? 3) Whether or, if there have, how the pressures on land resources from meeting the food requirements? To figure those questions out, we firstly use socio-economic pathways datasets, and historical food diet pattern classification to forecast the 2010-2050 food commodity and feed calories demand per country. A new food security indicator, which considered the influences of both the food energy and quality intake, was used to evaluate the food insecurity status and the distances to different targeted statuses of the specific country. The latest Global Agro-Ecological Zones (GAEZ) databases were used to estimate the current and future crop yield gap and crop potential production. For current to future scenario analysis, we considered population growth, dietary change, climate change, agricultural input level, and target food security status. Then the balance of food requirement with the current and potential crop production was analyzed for different scenarios. Land requirements were calculated for meeting those food requirements, and the pressures on land resources are evaluated. Our works are hoping to provide scientific-based evidences for policy recommendations for local government to tackle food insecurity problems in Sub-Saharan Africa.

Applications of remote sensing to water resources

NASA Technical Reports Server (NTRS)

1977-01-01

Analyses were made of selected long-term (1985 and beyond) objectives, with the intent of determining if significant data-related problems would be encountered and to develop alternative solutions to any potential problems. One long-term objective selected for analysis was Water Availability Forecasting. A brief overview was scheduled in FY-77 of the objective -- primarily a fact-finding study to allow Data Management personnel to gain adequate background information to perform subsequent data system analyses. This report, includes discussions on some of the larger problems currently encountered in water measurement, the potential users of water availability forecasts, projected demands of users, current sensing accuracies, required parameter monitoring, status of forecasting modeling, and some measurement accuracies likely to be achievable by 1980 and 1990.

Computational problems and signal processing in SETI

Deans, Stanley R.; Cullers, D. K.; Stauduhar, Richard

1991-01-01

The Search for Extraterrestrial Intelligence (SETI), currently being planned at NASA, will require that an enormous amount of data (on the order of 10 exp 11 distinct signal paths for a typical observation) be analyzed in real time by special-purpose hardware. Even though the SETI system design is not based on maximum entropy and Bayesian methods (partly due to the real-time processing constraint), it is expected that enough data will be saved to be able to apply these and other methods off line where computational complexity is not an overriding issue. Interesting computational problems that relate directly to the system design for processing such an enormous amount of data have emerged. Some of these problems are discussed, along with the current status on their solution.

Single dose treatment of malaria - current status and perspectives.

PubMed

Mischlinger, Johannes; Agnandji, Selidji T; Ramharter, Michael

2016-07-01

Despite increased international efforts for control and ultimate elimination, malaria remains a major health problem. Currently, artemisinin-based combination therapies are the treatment of choice for uncomplicated malaria exhibiting high efficacy in clinical trial settings in sub-Saharan Africa. However, their administration over a three-day period is associated with important problems of treatment adherence resulting in markedly reduced effectiveness of currently recommended antimalarials under real world settings. Antimalarial drug candidates and antimalarial drug combinations currently under advanced clinical development for the indication as single dose antimalarial therapy. Expert commentary: Several new drug candidates and combinations are currently undergoing pivotal proof-of-concept studies or clinical development programmes. The development of a single dose combination therapy would constitute a breakthrough in the control of malaria. Such an innovative treatment approach would simultaneously close the effectiveness gap of current three-day therapies and revolutionize population based interventions in the context of malaria elimination campaigns.

Prevalence and factors associated with depressive symptoms in Malay women.

Din, Meriam Omar; Noor, Noraini M

2009-12-01

Due to a dearth of research on depressive symptoms in Malaysia, particularly in Malay women, a community study was conducted to examine the prevalence and factors associated with current depressive symptoms in rural and urban Malay women with low socioeconomic status. Four hundred eighty-seven women (N rural = 242, N urban = 245) were interviewed. Information on socio-demographic variables, potential risk factors (family history of mental health problems, lifetime major depressive symptoms, and current life stressors), and current depressive symptoms (measured by the Centre for Epidemiologic Studies Depression Scale, CES-D) was collected. The prevalence of current depressive symptoms (CES-D scores > or = 16) reported was 34.5%, while the prevalence of lifetime major depressive symptoms was 27.5%. A significantly higher rate of current depressive symptoms was observed in urban women compared to rural women, chi(2) (1, N = 487) = 3.99, p < .05. However, no significant difference was found in the two groups of women in the prevalence of lifetime major depressive symptoms. The results of the multiple hierarchical regression analysis indicated that three potential factors (family history of mental health problems, lifetime major depressive symptoms, and current life stressors) were positively associated with current depressive symptoms, accounting for 17.8% of the variance, over and above the socio-demographic variables. The prevalence of depressive symptoms reported in the study was comparable to past studies. Among the factors associated with current depressive symptoms, the single most important was lifetime major depressive symptoms, followed by current life stressors, and family history of mental health problems. Among the socio-demographic variables used, perceived health status was the most important. The factors associated with depressive symptoms found in this study are consistent with past findings in the West, implying the universality of the phenomenon and common factors related to depressive symptoms in women.

Glass-Cockpit Pilot Subjective Ratings of Predictive Information, Collocation, and Mission Status Graphics: An Analysis and Summary of the Future Focus of Flight Deck Research Survey

NASA Technical Reports Server (NTRS)

Bartolone, Anthony; Trujillo, Anna

2002-01-01

NASA Langley Research Center has been researching ways to improve flight crew decision aiding for systems management. Our current investigation is how to display a wide variety of aircraft parameters in ways that will improve the flight crew's situation awareness. To accomplish this, new means are being explored that will monitor the overall health of a flight and report the current status of the aircraft and forecast impending problems to the pilots. The initial step in this research was to conduct a survey addressing how current glass-cockpit commercial pilots would value a prediction of the status of critical aircraft systems. We also addressed how this new type of data ought to be conveyed and utilized. Therefore, two other items associated with predictive information were also included in the survey. The first addressed the need for system status, alerts and procedures, and system controls to be more logically grouped together, or collocated, on the flight deck. The second idea called for the survey respondents opinions on the functionality of mission status graphics; a display methodology that groups a variety of parameters onto a single display that can instantaneously convey a complete overview of both an aircraft's system and mission health.

1979-01-01

The U.S. Geological Survey is active in the development and use of models for the analysis of various types of surface-water problems. Types of problems for which models have been, or are being developed, include categories such as the following: (1)specialized hydraulics, (2)flow routing in streams, estuaries, lakes, and reservoirs, (3) sedimentation, (4) transport of physical, chemical, and biological constituents, (5) surface exchange of heat and mass, (6) coupled stream-aquifer flow systems, (7) physical hydrology for rainfall-runoff relations, stream-system simulations, channel geometry, and water quality, (8) statistical hydrology for synthetic streamflows, floods, droughts, storage, and water quality, (9) management and operation problems, and (10) miscellaneous hydrologic problems. Following a brief review of activities prior to 1970, the current status of surface-water modeling is given as being in a developmental, verification, operational, or continued improvement phase. A list of recently published selected references, provides useful details on the characteristics of models.

Eutrophication status of the North Sea, Skagerrak, Kattegat and the Baltic Sea in present and future climates: A model study

2014-04-01

A method to combine observations and an ensemble of ecological models has been used to assess eutrophication. Using downscaled forcing from two GCMs under the A1B emission scenario, an assessment of the eutrophication status was made for a control (1970-2000) and a future climate (2070-2100) period. By using validation results from a hindcast to compute individual weights between the models, an assessment of eutrophication is done using a set of threshold values. The final classification distinguishes between three categories: problem area, potential problem area, and non-problem area, in accordance with current management practice as suggested by the Oslo and Paris Commissions (OSPAR) and the Helsinki Commission (HELCOM). For the control run the assessment indicates that the Kattegat, the Danish Straits, the Gulf of Finland, the Gotland Basin as well as main parts of the Arkona Basin, the Bornholm Basin, and the Baltic proper may be classified as problem areas. The main part of the North Sea and also the Skagerrak are non-problem areas while the main parts of the Gulf of Bothnia, Gulf of Riga and the entire southeastern continental coast of the North Sea may be classified as potential problem areas. In the future climate scenarios most of the previous potential problem areas in the Baltic Sea have become problem areas, except for the Bothnian Bay where the situation remain fairly unchanged. In the North Sea there seems to be no obvious changes in eutrophication status in the projected future climate.

How to Dax? Preschool Children's Prosocial Behavior, But Not Their Social Norm Enforcement Relates to Their Peer Status.

PubMed

Paulus, Markus

2017-01-01

The current study examined correlates of preschool children's ( n = 82) peer status. In particular, we assessed children's prosocial behavior, social problem behavior, norm enforcement, language abilities, and temperament. Children's prosocial behavior, pragmatic language abilities, and gender correlated with peer status. A regression analysis revealed that prosocial behavior and gender were independent predictors. There was some evidence for a mediation effect: The link between pragmatic language and peer status was mediated by prosocial behavior. Children's norm enforcement was not related to peer status, neither was it related to any other factor such as temperament or language. Overall, the study supports approaches claiming that prosocial behavior plays a role in children's social functioning and are in line with social-interactionist accounts to social and social-cognitive development.

The area of halal industry is the fastest growing global business across the world. The halal food industry is thus crucial for Muslims all over the world as it serves to ensure them that the food items they consume daily are syariah compliant. Currently, ontology has been widely used in computer sciences area such as web on the heterogeneous information processing, semantic web, and information retrieval. However, ontology has still not been used widely in the halal industry. Today, Muslim community still have problem to verify halal status for products in the market especially foods consisting of E number. This research tried to solve problem in validating the halal status from various halal sources. There are various chemical ontology from multilple databases found to help this ontology development. The E numbers in this chemical ontology are codes for chemicals that can be used as food additives. With this E numbers ontology, Muslim community could identify and verify the halal status effectively for halal products in the market.

Little is known about pathways to homelessness among older adults. We identified life course experiences associated with earlier versus later onset of homelessness in older homeless adults and examined current health and functional status by age at first homelessness. We interviewed 350 homeless adults, aged 50 and older, recruited via population-based sampling. Participants reported age at first episode of adult homelessness and their life experiences during 3 time periods: childhood (<18 years), young adulthood (ages 18–25), and middle adulthood (ages 26–49). We used a structured modeling approach to identify experiences associated with first adult homelessness before age 50 versus at age 50 or older. Participants reported current health and functional status, including recent mental health and substance use problems. Older homeless adults who first became homeless before 50 had more adverse life experiences (i.e., mental health and substance use problems, imprisonment) and lower attainment of adult milestones (i.e., marriage, full-time employment) compared to individuals with later onset. After multivariable adjustment, adverse experiences were independently associated with experiencing a first episode of homelessness before age 50. Individuals who first became homeless before age 50 had higher prevalence of recent mental health and substance use problems and more difficulty performing instrumental activities of daily living. Life course experiences and current vulnerabilities of older homeless adults with first homelessness before age 50 differed from those with later onset of homelessness. Prevention and service interventions should be adapted to meet different needs. PMID:27163478

Background: Very little research and survey have been performed on the occupational health, hazards, and working condition of urban and rural of workers in Qatar. The aim of the current study is to identify the health status, lifestyle condition, working-related problems, and accidents experienced by Indian subcontinental migrants (ISCM) in Qatar and their access to health-care facilities. Methods: This is a cross-sectional study based on a representative sample of 1186 workers and study covering sociodemographic characteristics, medical conditions, and health-seeking behaviors and personal experience. Results: There were statistically significant differences between semi-urban and urban migrant workers in terms of educational, occupation, income, working hours, and accommodation type (P < 0.001). Furthermore, there were statistically significant differences between migrant workers in terms of body mass index, delay in receiving salary, the right to medical insurance and sick day entitlement, cigarettes and shisha smoking, amenities, having on-site safety measure, and sleeping hours (P < 0.01). Moreover, there were statistically significant differences between semi-urban and urban migrant workers in terms of pain, cardiopulmonary, gastrointestinal, and pseudoneurologic and medical symptoms (P < 0.01). Multiple logistic regression was used for predictors’ health problems in migrant workers such as the absence of drinking water, tap water availability, safety facility tools, occupational status, shisha smoking, toilet facility, working hours, and accommodation type were considered the strong predictors. Conclusions: The current study revealed that there is a lack of insufficient information for the migrants about their lifestyle, medical conditions, health risks, injury, and rights privilege in relation to legal working condition and health services.

Very little research and survey have been performed on the occupational health, hazards, and working condition of urban and rural of workers in Qatar. The aim of the current study is to identify the health status, lifestyle condition, working-related problems, and accidents experienced by Indian subcontinental migrants (ISCM) in Qatar and their access to health-care facilities. This is a cross-sectional study based on a representative sample of 1186 workers and study covering sociodemographic characteristics, medical conditions, and health-seeking behaviors and personal experience. There were statistically significant differences between semi-urban and urban migrant workers in terms of educational, occupation, income, working hours, and accommodation type ( P < 0.001). Furthermore, there were statistically significant differences between migrant workers in terms of body mass index, delay in receiving salary, the right to medical insurance and sick day entitlement, cigarettes and shisha smoking, amenities, having on-site safety measure, and sleeping hours ( P < 0.01). Moreover, there were statistically significant differences between semi-urban and urban migrant workers in terms of pain, cardiopulmonary, gastrointestinal, and pseudoneurologic and medical symptoms ( P < 0.01). Multiple logistic regression was used for predictors' health problems in migrant workers such as the absence of drinking water, tap water availability, safety facility tools, occupational status, shisha smoking, toilet facility, working hours, and accommodation type were considered the strong predictors. The current study revealed that there is a lack of insufficient information for the migrants about their lifestyle, medical conditions, health risks, injury, and rights privilege in relation to legal working condition and health services.

Retired and former asbestos workers in Hawaii

Fournier-Massey, G.; Wong, G.; Hall, T.C.

1984-01-01

In 1979, a pilot survey defined respiratory status and unmet health care needs of retired and former male asbestos workers in Hawaii. Of 1,401 identified subjects, 741 were contacted and 411 were interviewed. Forty-five subjects were between 39 and 54 years of age; 208, between 55 and 64; and 158, age 65 or more. They represented the main ethnic groups--Caucasian, Chinese, Filipino, Hawaiian and part-Hawaiian, and Japanese--on Oahu. Most subjects had had significant exposure to asbestos in a shipyard, and 83% were current nonsmokers (160 had never smoked, and 111 were ex-smokers for ten years or more). Taking age andmore » ethnicity into account, our group had more chronic respiratory and gastrointestinal problems than the comparable male population of Oahu in 1979, but fewer such problems than active shipyard workers elsewhere. These problems related primarily to current smoking status and secondarily to the length of asbestos exposure. Health care was available, but former workers used it less than retirees, despite having more symptoms. Very few abnormalities were reported by the subjects on their chest X-rays, pulmonary function tests, and sputum cytology performed elsewhere. These findings are compared to those of other shipyards, and support the hypothesis that the biological effects of asbestos exposure are generally mild in Hawaii.« less

Assessing Bisexual Stigma and Mental Health Status: A Brief Report

PubMed Central

Bostwick, Wendy

2013-01-01

Bisexual women often report higher rates of depression and mental health problems than their heterosexual and lesbian counterparts. These disparities likely occur, in part, as a result of the unique stigma that bisexual women face and experience. Such stigma can in turn operate as a stressor, thereby contributing to poor mental health status. The current pilot study tested a new measure of bisexual stigma and its association with mental health. Results suggest a moderate positive correlation between the two, and point to areas for future consideration when measuring bisexual stigma. PMID:24683314

2012-01-01

Objective To determine the relationship between functional status (independent activities of daily living) and judgment/problem solving and the extent to which select demographic characteristics such as dementia subtype and cognitive measures may moderate that relationship in older adult individuals with dementia. Methods The National Alzheimer’s Coordinating Center Universal Data Set was accessed for a study sample of 3,855 individuals diagnosed with dementia. Primary variables included functional status, judgment/problem solving, and cognition. Results Functional status was related to judgment/problem solving (r= 0.66; p< .0005). Functional status and cognition jointly predicted 56% of the variance in judgment/problem solving (R-squared = .56, p <.0005). As cognition decreases, the prediction of poorer judgment/problem solving by functional status became stronger. Conclusions Among individuals with a diagnosis of dementia, declining functional status as well as declining cognition should raise concerns about judgment/problem solving. PMID:22786576

Relationships Among Intimate Partner Violence, Work, and Health.

Wathen, C Nadine; MacGregor, Jennifer C D; MacQuarrie, Barbara J

2018-07-01

Intimate partner violence (IPV) is a major public health problem, and recent attention has focused on its impact on workers and workplaces. We provide findings from a pan-Canadian online survey on the relationships among IPV, work, and health. In total, 8,429 people completed the survey, 95.5% of them in English and 78.4% female. Reflecting the recruitment strategy, most (95.4%) were currently working, and unionized (81.4%). People with any lifetime IPV experience reported significantly poorer general health, mental health, and quality of life; those with both recent IPV and IPV experience over 12 months ago had the poorest health. Among those who had experienced IPV, about half reported that violence occurred at or near the workplace, and these people generally had poorer health outcomes. Employment status moderated the relationship between IPV exposure and health status, with those who were currently working and had experienced IPV having similar health status to those without IPV experience who were not employed. While there were gender differences in IPV experience, in the impacts of IPV at work, and in health status, gender did not moderate any associations. In this very large data set, we found robust relationships among different kinds of IPV exposure (current, recent, and lifetime), health and quality of life, and employment status, including the potentially protective effect of current employment on health for both women and men. Our findings may have implications for strategies to address IPV in workplaces, and should reinforce emerging evidence that IPV is also an occupational health issue.

The effects of maternal working conditions and mastery on child behavior problems: studying the intergenerational transmission of social control.

PubMed

Rogers, S J; Parcel, T L; Menaghan, E G

1991-06-01

We assess the impact of maternal sense of mastery and maternal working conditions on maternal perceptions of children's behavior problems as a means to study the transmission of social control across generations. We use a sample of 521 employed mothers and their four-to six-year-old children from the National Longitudinal Survey's Youth Cohort in 1986. Regarding working conditions, we consider mother's hourly wage, work hours, and job content including involvement with things (vs. people), the requisite level of physical activity, and occupational complexity. We also consider maternal and child background and current family characteristics, including marital status, family size, and home environment. Maternal mastery was related to fewer reported behavior problems among children. Lower involvement with people and higher involvement with things, as well as low physical activity, were related significantly to higher levels of perceived problems. In addition, recent changes in maternal marital status, including maternal marriage or remarriage, increased reports of problems; stronger home environments had the opposite effect. We interpret these findings as suggesting how maternal experiences of control in the workplace and personal resources of control can influence the internalization of control in children.

Mao, Y. F.; Li, J. R.; Deng, L. J.

2008-10-01

Automatically Switched Optical Network (ASON) is currently a new and hot research subject in the world. It can provide high bandwidth, high assembly flexibility, high network security and reliability, but with a low management cost. It is presented to meet the requirements for high-throughput optical access with stringent Quality of Service (QoS). But as a brand new technology, ASON can not be supported by the traditional protocol software and network equipments. And the approach to build a new ASON network on the basis of completely abandoning the traditional optical network facilities is not desirable, because it costs too much and wastes a lot of network resources can also be used. So how to apply ASON to the current networks and realize the smooth transition between the existing network and ASON has been a serious problem to many network operators. In this research, the status in quo of ASON is introduced first and then the key problems should be considered when applying ASON to current networks are discussed. Based on this, the strategies should be complied with to overcome these key problems are listed. At last, the approach to apply ASON to the current optical networks is proposed and analyzed.

Objective. Existing research shows a serious scarcity of EBPH practice in China and other developing regions; as an exploratory study, this study aimed to assess the current EBPH implementation status in Shanghai of China qualitatively. Methods. Using semistructured key informant interviews, we examined the status of and impediments to the lagging EBPH in China. Data were analyzed based on the Consolidated Framework for Implementation Research (CFIR). Results. Chinese public health practitioners knew more about evidence-based medicine but less about EBPH. The situation was worse in community healthcare centers. Participants perceived that evidence sources were limited and the quality of evidence was low. Concerning the inner setting factors, the structural characteristics, networks and communications, implementation climate, and leadership engagement were confronted with many problems. Among the outer setting factors, external government policies and incentives and low patient compliance were the key problems. Additionally, public health practitioners in Shanghai lacked sufficient awareness of EBPH. Furthermore, the current project-based EBPH lacks a systematic implementation system. Conclusions. Existing practical perspectives on EBPH indicate a lag in the advocacy of this new ideology in China. It would be advisable for healthcare institutions to take the initiative to explore feasible and multiple methods of EBPH promotion.

Approaches of researches in medical geography in Poland and Ukraine

Pantylej, Wiktoria

2008-01-01

This paper deals with the historical review of medical geography in the world, in Poland and in Ukraine. There are different approaches in medical geography: according to the research subject (ecological and economic approaches) and according to the current affairs of research (approach concerns sexuality, the age of the population and accordingly, accessibility of health care services to the population). To the author's mind, the most perspective approaches in medical geography in Poland and Ukraine are as follows: - integrative - dedicated to the health status of the population in connection with the quality and life level; - mathematical-statistical - connected with the problem of synthetic indexes of health status of the populations and factors influencing it, and with the problem of economic value of health and life of the population; - social-economic - the analysis of the influence of socioeconomic factors (such as wealth measure, rate of unemployment, work conditions and others) on public health; - ecological - connected with the researches dedicated to the analysis of environmental impact on public health status of the population; - demographical - the analysis of demographical factors of forming public health status; - social-psychological - health culture of the population, perception of the own health/morbidity and health care systems existing in different countries.

What Happens After Treatment? Long-Term Effects of Continued Substance Use, Psychiatric Problems and Help-Seeking on Social Status of Alcohol-Dependent Individuals.

2018-03-30

We examined whether alcohol-dependent individuals with sustained substance use or psychiatric problems after completing treatment were more likely to experience low social status and whether continued help-seeking would improve outcomes. Ongoing alcohol, drug and psychiatric problems after completing treatment were associated with increased odds of low social status (unemployment, unstable housing and/or living in high-poverty neighborhood) over 7 years. The impact of drug problems declined over time, and there were small, delayed benefits of AA attendance on social status. Alcohol-dependent individuals sampled from public and private treatment programs (N = 491; 62% male) in Northern California were interviewed at treatment entry and 1, 3, 5 and 7 years later. Random effects models tested relationships between problem severity (alcohol, drug and psychiatric problems) and help-seeking (attending specialty alcohol/drug treatment and Alcoholics Anonymous, AA) with low social status (unemployment, unstable housing and/or living in a high-poverty neighborhood) over time. The proportion of participants experiencing none of the indicators of low social status increased between baseline and the 1-year follow-up and remained stable thereafter. Higher alcohol problem scores and having any drug and/or psychiatric problems in the years after treatment were associated with increased odds of low social status over time. An interaction of drug problems with time indicated the impact of drug problems on social status declined over the 7-year period. Both treatment-seeking and AA attendance were associated with increased odds of low social status, although lagged models suggested there were small, delayed benefits of AA attendance on improved social status over time. Specialty addiction treatment alone was not sufficient to have positive long-term impacts on social status and social integration of most alcohol-dependent people.

Evaluation of the Interactionist Model of Socioeconomic Status and Problem Behavior: A Developmental Cascade across Generations

2010-01-01

The current multigenerational study evaluates the utility of the Interactionist Model of Socioeconomic Influence on human development (IMSI) in explaining problem behaviors across generations. The IMSI proposes that the association between socioeconomic status (SES) and human development involves a dynamic interplay that includes both social causation (SES influences human development) and social selection (individual characteristics affect SES). As part of the developmental cascade proposed by the IMSI, the findings from this investigation showed that G1 adolescent problem behavior predicted later G1 SES, family stress, and parental emotional investments, as well as the next generation of children's problem behavior. These results are consistent with a social selection view. Consistent with the social causation perspective, we found a significant relation between G1 SES and family stress, and in turn, family stress predicted G2 problem behavior. Finally, G1 adult SES predicted both material and emotional investments in the G2 child. In turn, emotional investments predicted G2 problem behavior, as did material investments. Some of the predicted pathways varied by G1 parent gender. The results are consistent with the view that processes of both social selection and social causation account for the association between SES and human development. PMID:20576188

Status of the Magma Energy Project

Dunn, J. C.

The current magma energy project is assessing the engineering feasibility of extracting thermal energy directly from crustal magma bodies. The estimated size of the U.S. resource (50,000 to 500,000 quads) suggests a considerable potential impact on future power generation. In a previous seven-year study, we concluded that there are no insurmountable barriers that would invalidate the magma energy concept. Several concepts for drilling, energy extraction, and materials survivability were successfully demonstrated in Kilauea Iki lava lake, Hawaii. The present program is addressing the engineering design problems associated with accessing magma bodies and extracting thermal energy for power generation. The normal stages for development of a geothermal resource are being investigated: exploration, drilling and completions, production, and surface power plant design. Current status of the engineering program and future plans are described.

Psychological problems and psychosocial predictors of cigarette smoking behavior among undergraduate students in Malaysia.

PubMed

Saravanan, Coumaravelou; Heidhy, Imran

Cigarette smokers have their own motivation and justification to smoke. For example, smoking reduces their stress or enhances their pleasure. This study aimed to identify the (a) prevalence of cigarette smokers among undergraduates in Malaysia, (b) gender differences in nicotine dependence among current smokers, (c) differences in psychological problems (depression, anxiety and stress) based on the status of smoking cigarettes (current, former and non-smokers) and (d) extent to which precipitating factors (tension reduction, addiction, automatism, handling, social interaction, pleasure, and stimulation) predict the smoking behavior among current smokers. In this study 780 undergraduate students participated from a private university in Kuala Lumpur and Selangor state in Malaysia. The Depression, Stress and Anxiety Scale, Modified Reason for Smoking Scale and Fagerstrom Nicotine Dependence Test were used to measure psychological problems, predictors of smoking behavior and nicotine dependency among current smokers. The results showed that 14.7%(n=106) of the students were smokers. Current smokers exhibited more psychological problems (depression, anxiety and stress) compared to former and non-smokers. Addiction, tension reduction, pleasure and automatism were predictors of smoking behavior among the current smoking students. Step wise regression analysis showed that smoking behavior was highly predicted by nicotine dependency or addiction. Smoking students were motivated to smoke cigarettes as they believed that it reduced their tension and enhance pleasure. Hence, there is a need for health promotion and anti-tobacco prevention as cigarette smokers experience more psychological problems. Nicotine dependency or addition was one of the major causes for smoking behavior among the student population in Malaysia.

An international seminar on the treatment and laboratory diagnosis of yellow fever, sponsored by the Pan American Health Organization (PAHO) and held in 1984, differed from previous meetings on yellow fever because of its emphasis on the care and management of patients and because the participants included specialists from several branches of medicine, such as hepatology, haematology, cardiology, infectious diseases, pathology and nephrology. The meeting reviewed the current status of yellow fever and problems associated with case-finding and notification; features of yellow fever in individual countries of Latin America; health services and facilities for medical care as they relate to diagnosis and management of cases; prevention strategies for and current status of immunization programmes; clinical and pathological aspects of yellow fever in humans; pathogenesis and pathophysiology of yellow fever in experimental animal models; clinical and specific laboratory diagnosis; treatment of the disease and of complications in the functioning of individual organ systems; prognosis and prognostic indicators; and directions for future clinical and experimental research on pathophysiology and treatment.

Shao, N

1981-01-01

The author first provides some basic demographic data for India and points out that the current annual rate of population growth of 2.45 percent is slightly higher than the annual increase in food production. Problems in the areas of employment, education, housing, and transportation, as well as the general problem of poverty, are seen as a consequence of this imbalance. The lack of success of the national family planning program is attributed primarily to the failure to achieve a satisfactory rate of economic growth. Contributory factors include early marriage, the low status of women, the desire for large families, and administrative problems associated with the family planning program.

Recent developments with boron as a platform for novel drug design.

Leśnikowski, Zbigniew J

2016-06-01

After decades of development, the medicinal chemistry of compounds that contain a single boron atom has matured to the present status of having equal rights with other branches of drug discovery, although it remains a relative newcomer. In contrast, the medicinal chemistry of boron clusters is less advanced, but it is expanding and may soon become a productive area of drug discovery. The author reviews the current developments of medicinal chemistry of boron and its applications in drug design. First generation boron drugs that bear a single boron atom and second generation boron drugs that utilize boron clusters as pharmacophores or modulators of bioactive molecules are discussed. The advantages and gaps in our current understanding of boron medicinal chemistry, with a special focus on boron clusters, are highlighted. Boron is not a panacea for every drug discovery problem, but there is a good chance that it will become a useful addition to the medicinal chemistry tool box. The present status of boron resembles the medicinal chemistry status of fluorine three decades ago; indeed, currently, approximately 20% of pharmaceuticals on the market contain fluorine. The fact that novel boron compounds, especially those based on abiotic polyhedral boron hydrides, are currently unfamiliar could be advantageous because organisms may be less prone to developing resistance against boron cluster-based drugs.

Health and nutritional status of children in Ethiopia: do maternal characteristics matter?

PubMed

Seid, Abdu Kedir

2013-03-01

In Ethiopia, despite some recent improvements, the health and nutritional status of children is very poor. A better understanding of the main socioeconomic determinants of child health and nutrition is essential to address the problem and make appropriate interventions. In the present study, an attempt is made to explore the effect of maternal characteristics on the health and nutritional status of under-five children using the 2005 Ethiopian Demographic and Health Survey. The health and nutritional status of children are measured using the two widely used anthropometric indicators height-for-age (HAZ) and weight-for-height (WHZ). In the ordinary least squares (OLS) estimation, it is observed that maternal characteristics have a significant impact on child health and nutritional status. The magnitudes of the coefficients, however, are found to slightly increase when maternal education is instrumented in the 2SLS estimation. Moreover, in the quantile regression (QR) estimation, the impacts of maternal characteristics are observed to vary between long-term and current child health and nutritional status.

Perceived Race-Based Discrimination, Employment Status, and Job Stress in a National Sample of Black Women: Implications for Health Outcomes

Mays, Vickie M.; Coleman, Lerita M.; Jackson, James S.

2013-01-01

Previous research has not systematically examined the relationship of perceived race-based discriminations to labor force participation or job related stresses–problems experienced by Black women. The present study investigated the relative contributions of perceived race-based discriminations and sociodemographic characteristics to employment status and job stress in a national probability sample (the National Survey of Black Americans; J. S. Jackson, 1991) of Black women in the United States. Logit and polychotomous logistic regression analyses revealed that Black women’s current employment status was best explained by sociodemographic measures. In contrast, the combination of perceived discrimination and sociodemographics differentially affects patterns of employment status and perceived job stress in the work environment of Black women. Implications of these findings for the health of African American women are discussed. PMID:9547054

A reconceptualization of age stratification in China.

PubMed

Yin, P; Lai, K H

1983-09-01

Using the concepts of age stratification theory--age effect, cohort effect, and subcohort differences--this paper provides a new perspective on age stratification in China. Currently, the literature suggests that the status of elderly people declined after the Communist Revolution and will further decline with modernization. We discuss the problems with this perspective and argue, instead, that the status of elderly adults did not decline for the majority of the aged during the Maoist years. Rather, the most important change in the age stratification system during the Maoist years was the change in the criterion of age stratification--from age differences to cohort and subcohort differences. Furthermore, the subcohort of elderly adults who suffered the most status decline during the Maoist years--the bourgeoisie--may actually enjoy an increase in status with the recent modernization impetus. Research suggestions from this new perspective are discussed.

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

Currently, the problem at hand is in distributing identical copies of OEP and filter software to a large number of farm nodes. One of the common methods used to transfer these softwares is through unicast. Unicast protocol faces the problem of repetitiously sending the same data over the network. Since the sending rate is limited, this process poses to be a bottleneck. Therefore, one possible solution to this problem lies in creating a reliable multicast protocol. A specific type of multicast protocol is the Bulk Multicast Protocol [4]. This system consists of one sender distributing data to many receivers. Themore » sender delivers data at a given rate of data packets. In response to that, the receiver replies to the sender with a status packet which contains information about the packet loss in terms of Negative Acknowledgment. The probability of the status packet sent back to the sender is+, where N is the number of receivers. The protocol is designed to have approximately 1 status packet for each data packet sent. In this project, we were able to show that the time taken for the complete transfer of a file to multiple receivers was about 12 times faster with multicast than by the use of unicast. The implementation of this experimental protocol shows remarkable improvement in mass data transfer to a large number of farm machines.« less

Objective Self‐perceived health status may be helpful in identifying patients at high risk for adverse outcomes. The Euro Heart Survey on Coronary Revascularization (EHS‐CR) provided an opportunity to explore whether impaired health status was a predictor of 1‐year mortality in patients with coronary artery disease (CAD) undergoing angiographic procedures. Methods Data from the EHS‐CR that included 5619 patients from 31 member countries of the European Society of Cardiology were used. Inclusion criteria for the current study were completion of a self‐report measure of health status, the EuroQol Questionnaire (EQ‐5D) at discharge and information on 1‐year follow‐up, resulting in a study population of 3786 patients. Results The 1‐year mortality was 3.2% (n = 120). Survivors reported fewer problems on the five dimensions of the EQ‐5D as compared with non‐survivors. A broad range of potential confounders were adjusted for, which reached a p<0.10 in the unadjusted analyses. In the adjusted analyses, problems with self‐care (OR 3.45; 95% CI 2.14 to 5.59) and a low rating (⩽60) on health status (OR 2.41; 95% CI 1.47 to 3.94) were the most powerful independent predictors of mortality, among the 22 clinical variables included in the analysis. Furthermore, patients who reported no problems on all five dimensions had significantly lower 1‐year mortality rates (OR 0.47; 95% CI 0.28 to 0.81). Conclusions This analysis shows that impaired health status is associated with a 2–3‐fold increased risk of all‐cause mortality in patients with CAD, independent of other conventional risk factors. These results highlight the importance of including patients' subjective experience of their own health status in the evaluation strategy to optimise risk stratification and management in clinical practice.

Hierarchical social status greatly influences behavior and health. Human and animal studies have begun to identify the brain regions that are activated during the formation of social hierarchies. They point towards the prefrontal cortex (PFC) as a central regulator, with brain areas upstream of the PFC conveying information about social status, and downstream brain regions executing dominance behavior. This review summarizes our current knowledge on the neural circuits that control social status. We discuss how the neural mechanisms for various types of dominance behavior can be studied in laboratory rodents by selective manipulation of neuronal activity or synaptic plasticity. These studies may help in finding the cause of social stress-related mental and physical health problems. Copyright © 2014 Elsevier Ltd. All rights reserved.

2012-04-01

Chinese dental technicians play a significant role in the globalised market of dental prosthesis fabrication, but this subject has not been investigated in detail. The demand for dental prostheses increases as individuals pay increasing attention to their oral health. Therefore, it is important to investigate the status of Chinese dental technicians. To evaluate the current status of Chinese dental technicians. Dental technicians' resumés, which reveal information regarding dental technician manpower, degrees, working age and salary, etc., were analysed and compared with those abroad. We also estimated the future demands of dental technician manpower, and discussed some potential solutions. There are fewer dental technicians in China than in other developed countries; they are also of a lower standard. Male technicians outnumber females. The education level of technicians is insufficient, and the education programme is still in its exploratory stage. The development of dental technician teams in China represents both an opportunity and a challenge. It is important to move forward from the current situation to yield long-term development. This article provides information on the Chinese dental technology industry, identifies the problems and offers solutions for its development. © 2012 FDI World Dental Federation.

Honing the Priorities and Making the Investment Case for Global Health.

Mundel, Trevor

2016-03-01

In the aftermath of the Ebola crisis, the global health community has a unique opportunity to reflect on the lessons learned and apply them to prepare the world for the next crisis. Part of that preparation will entail knowing, with greater precision, what the scale and scope of our specific global health challenges are and what resources are needed to address them. However, how can we know the magnitude of the challenge, and what resources are needed without knowing the current status of the world through accurate primary data? Once we know the current status, how can we decide on an intervention today with a predicted impact decades out if we cannot project into that future? Making a case for more investments will require not just better data generation and sharing but a whole new level of sophistication in our analytical capability--a fundamental shift in our thinking to set expectations to match the reality. In this current status of a distributed world, being transparent with our assumptions and specific with the case for investing in global health is a powerful approach to finding solutions to the problems that have plagued us for centuries.

Abstract Dengue is a significant global health problem. Even though a vaccine against dengue is now available, which is a notable achievement, its long-term protective efficacy against each of the 4 dengue virus serotypes remains to be definitively determined. Consequently, drugs directed at the viral targets or critical host mechanisms that can be used safely as prophylaxis or treatment to effectively ameliorate disease or reduce disease severity and fatalities are still needed to reduce the burden of dengue. This review will provide a brief account of the status of therapeutics research and development for dengue. PMID:28403438

Emotional and behavioral problems in migrant children and adolescents in Europe: a systematic review.

2014-06-01

Based on findings of Stevens and Vollebergh [69], who analyzed cross-cultural topics, this review considers the current prevalence of emotional and behavioral problems of native children and adolescents in comparison with children with a migration background in European countries. 36 studies published from 2007 up to 2013 chosen from a systematic literature research were included and analyzed in their perspective design in detail. Previous studies showed great differences in their results: Especially in Germany, many studies compare the heterogeneous group of immigrant children with native children to analyze an ethnic minority or migration process effect. Only a British and Turkish study demonstrates the selection effect in migration. Most Dutch or British studies examined different ethnic groups, e.g. Turkish, Moroccan, Surinamese, Pakistani, Indian or Black migrant children and adolescents. Migrant childhood in Europe could be declared a risk in increasing internalizing problem behavior while the prevalent rate in externalizing problem behavior was comparable between native and migrant children. A migration status itself can often be postulated as a risk factor for children's mental condition, in particular migration in first generation. Furthermore, several major influence factors in migrant children's mental health could be pointed out, such as a low socio-economic status, a Non-European origin, an uncertain cultural identity of the parents, maternal harsh parenting or inadequate parental occupation, a minority status, the younger age, gender effects or a specific culture declaration in diseases.

Sport-related achievement motivation and alcohol outcomes: an athlete-specific risk factor among intercollegiate athletes.

2013-12-01

Intercollegiate athletes report greater alcohol consumption and more alcohol-related problems than their non-athlete peers. Although college athletes share many of the same problems faced by non-athletes, there are some consequences that are unique to athletes. Studies have demonstrated that alcohol negatively affects athletic performance including increased dehydration, impeded muscle recovery, and increased risk for injury. Beyond risk factors for alcohol misuse that may affect college students in general, research has begun to examine risk factors that are unique to collegiate athletes. For example, research has found that off-season status, the leadership role, and athlete-specific drinking motives are associated with increased alcohol use. Given these findings, it is possible that other athlete-specific variables influence alcohol misuse. One such variable may be sport achievement orientation. The purpose of the current study was to examine the relationship between sport achievement orientation and alcohol outcomes. Given previous research regarding seasonal status and gender, these variables were examined as moderators. Varsity athletes (n=263) completed the Sport Orientation Questionnaire, which assesses sport-related achievement orientation on three scales (Competitiveness, Win Orientation, and Goal Orientation). In addition, participants completed measures of alcohol use and alcohol-related problems. Results indicated that Competitiveness, Win Orientation, and Goal Orientation were all significantly associated with alcohol use, but not alcohol-related problems. Moreover, these relationships were moderated by seasonal status and gender. These interactions, clinical implications, and limitations are discussed. © 2013.

Burnout is a special type of prolonged occupational stress that is linked with numerous psychosomatic and psychological sequelae and negative job consequences. The purpose of this study is to estimate the contribution of occupational and substance use factors to burnout among a multiethnic sample of urban transit operators (n = 1231). Survey and medical exam data were obtained from participants in the 1993-1995 San Francisco MUNI Health & Safety Study. Burnout was measured with the Maslach Burnout Inventory emotional exhaustion subscale. Occupational factors included frequency of job problems (e.g., equipment, passengers, and traffic), years driving, full or part-time work status, and ergonomic problems (e.g., adjusting the seat, back support, vibration, and rocking or bouncing of seat). Substance use measures were alcohol consumption and smoking status (i.e., current, former, and never smokers). The results of multivariable linear regression analysis showed that job problems (beta = 0.426, p < 0.001), ergonomic problems (beta = 0.138, p < 0.001), and full-time work status (beta = 0.070, p < 0.01) were associated with burnout. Smoking was not significant, but alcohol consumption was positively associated with burnout (beta = 0.067, p < 0.01). Age was negatively correlated with burnout (beta = -0.106, p < 0.001), which may reflect a healthy worker effect. Because aspects of the psychosocial and physical work environments can be modified, the findings have important implications for the prevention of burnout among municipal transit operators.

Smoking and body weight as markers of fitness for duty among U.S. military personnel.

Both tobacco and overweight present serious threats to public health. Although the military has targeted both health issues, only weight status is included in tests of fitness. This study contrasted the relative utility of body weight and smoking as markers for fitness for duty. Using data from the 2002 Department of Defense Survey of Health-Related Behaviors among Military Personnel (N = 12,149; 24.7% female), troops were categorized according to weight (underweight, healthy weight, overweight, or obese) and smoking status (never smoker, former smoker, or current smoker). Logistic models were developed to examine the usefulness of smoking status and weight status as predictors of items assessing four domains of military fitness for duty, namely, physical health, mental health, substance abuse, and legal problems. Smoking status was a consistent and strong predictor of items within all four fitness domains. In contrast, weight status was not a consistent predictor of fitness. The military should consider adding smoking status to assessments of military fitness. Also, given that underweight and not overweight status predicted negative outcomes among military members, the services should consider revising their weight status fitness standards.

As the restaurant delivery robot is often in a dynamic and complex environment, including the chairs inadvertently moved to the channel and customers coming and going. The traditional Markov decision process path planning algorithm is not save, the robot is very close to the table and chairs. To solve this problem, this paper proposes the Markov Decision Process with a penalty term called MDPPT path planning algorithm according to the traditional Markov decision process (MDP). For MDP, if the restaurant delivery robot bumps into an obstacle, the reward it receives is part of the current status reward. For the MDPPT, the reward it receives not only the part of the current status but also a negative constant term. Simulation results show that the MDPPT algorithm can plan a more secure path.

Motherhood is respected in the workplace in Japan, and in order to provide an environment in which women can work and still bear and rear children with a sense of security, laws concerning maternal protection of female workers, and revisions in terms of the system have been made, and a new system has been in effect since the fiscal year of 1998. Nevertheless, gender discrimination against women and the disparagement of women, rooted in gender role stereotypes concerning the division of labor, remain firmly planted in the social environment and in long-established custom.

Pangolins are unique placental mammals with eight species existing in the world, which have adapted to a highly specialized diet of ants and termites, and are of significance in the control of forest termite disaster. Besides their ecological value, pangolins are extremely important economic animals with the value as medicine and food. At present, illegal hunting and habitat destruction have drastically decreased the wild population of pangolins, pushing them to the edge of extinction. Captive breeding is an important way to protect these species, but because of pangolin's specialized behaviors and high dependence on natural ecosystem, there still exist many technical barriers to successful captive breeding programs. In this paper, based on the literatures and our practical experience, we reviewed the status and existing problems in captive breeding of pangolins, including four aspects, the naturalistic habitat, dietary husbandry, reproduction and disease control. Some recommendations are presented for effective captive breeding and protection of pangolins.

The critical system analysis of the current status of all areas of human activity on the planet Earth (in Europe and the Slovak Republic) convinces us, that this development is unsustainable. Many prominent personalities of scientific, cultural, social and political life stated that our planet Earth and mankind with it, and all that man has created during its existence is only one step finds itself on the brink of disaster and it will turn against man. Many theoretical concepts, based on the historical development and experience notes that this status is natural and inevitable. However, we hold a different opinion. If the man is team, that is declared, it must show (now at the turning point) themselves and future generations, that it thinks with its existence on planet Earth seriously and responsibly. Given by the current global crisis and also our belief that the fundamental problem of humanity is unfair creation and distribution of wealth on planet Earth, we maintain opinion for changing the paradigm of thinking in this area. As the only alternative for solving this problem we see in the application of the concept of sustainable corporate social responsibility. The article presents our idea.

Mycobacterium avium subspecies paratuberculosis (MAP) has emerged as a major health problem for domestic livestock and human beings. Reduced per animal productivity of domestic livestock seriously impacts the economics of dairy farming globally. High to very high bioload of MAP in domestic livestock and also in the human population has been reported from north India. Presence of live MAP bacilli in commercial supplies of raw and pasteurized milk and milk products indicates its public health significance. MAP is not inactivated during pasteurization, therefore, entering into human food chain daily. Recovery of MAP from patients with inflammatory bowel disease or Crohn's disease and animal healthcare workers suffering with chronic gastrointestinal problems indicate a close association of MAP with a number of chronic and other diseases affecting human health. Higher bioload of MAP in the animals increases the risk of exposure to the human population with MAP. This review summarizes the current status of MAP infection in animals as well as in human beings and also highlights the prospects of effective management and control of disease in animals to reduce the risk of exposure to human population.

The purpose of this study was to ascertain the current statuses and problems of dental home care patients by surveying the oral care status and needs of patients in the home medical care support ward at the National Center for Geriatrics and Gerontology. Patients that required continuous oral management even after discharge from the hospital were referred to local dental clinics to receive home dental care. We investigated the suitability and problems associated with such care, and identified the dental care needs of home patients and the status of local care coordination, including those in hospitals. The subjects were 82 patients. We ascertained their general condition and oral status, and also investigated the problems associated with patients judged to need specialized oral care by a dentist during oral treatment. Patients who required continuous specialized oral care after discharge from hospital were referred to dental clinics that could provide regular care, and the problems at the time of referral were identified. Dry mouth was reported by many patients. A large number of patients also needed specialized dental treatment such as the removal of dental calculus or tooth extraction. Problems were seen in oral function, with 38 of the patients (46%) unable to gargle and 23 (28%) unable to hold their mouths open. About half of the patients also had dementia, and communication with these patients was difficult. Of the 43 patients who were judged to need continuing oral care after discharge from hospital, their referral to a dental clinic for regular care was successful for 22 (51%) patients and unsuccessful for 21 (49%) patients. The reasons for unsuccessful referrals included the fact that the family, patient, nurse, or caregiver did not understand the need for specialized oral care. The present results suggest the need for specialized oral treatment in home medical care. These findings also suggest that coordinating seamless dental care among primary physicians, intermediates, and transferring care after hospital discharge to regular dentists is difficult.

Undernutrition among older people is a continuing source of concern, particularly among acutely hospitalized patients. The purpose of the current study is to compare malnourished elderly patients with those at nutritional risk and identify factors contributing to the variability between the groups. The study was carried out at the Soroka University Medical Center in the south of Israel. From September 2003 through December 2004, all patients 65 years-of-age or older admitted to any of the internal medicine departments, were screened within 72 hours of admission to determine nutritional status using the short version of the Mini Nutritional Assessment (MNA-SF). Patients at nutritional risk were entered the study and were divided into malnourished or 'at risk' based on the full version of the MNA. Data regarding medical, nutritional, functional, and emotional status were obtained by trained interviewers. Two hundred fifty-nine elderly patients, 43.6% men, participated in the study; 18.5% were identified as malnourished and 81.5% were at risk for malnutrition according to the MNA. The malnourished group was less educated, had a higher depression score and lower cognitive and physical functioning. Higher prevalence of chewing problems, nausea, and vomiting was detected among malnourished patients. There was no difference between the groups in health status indicators except for subjective health evaluation which was poorer among the malnourished group. Lower dietary score indicating lower intake of vegetables fruits and fluid, poor appetite and difficulties in eating distinguished between malnourished and at-risk populations with the highest sensitivity and specificity as compare with the anthropometric, global, and self-assessment of nutritional status parts of the MNA. In a multivariate analysis, lower cognitive function, education <12 years and chewing problems were all risk factors for malnutrition. Our study indicates that low food consumption as well as poor appetite and chewing problems are associated with the development of malnutrition. Given the critical importance of nutritional status in the hospitalized elderly, further intervention trials are required to determine the best intervention strategies to overcome these problems.

Recent advances in assisted reproductive technology (ART) have made it possible to circumvent many causes of male and female infertility. The right to have a child by ART has been respected for infertile couples. However, there are currently no legal regulations concerning ART in Japan, and this has resulted in social and ethical problems. Surrogacy involves particularly complex medical, ethical, social, and legal issues, and is frequently focused on as a major social concern. Uterine transplantation (UTx) is a potential alternative for young women with uterine factor infertility due to hysterectomy for treatment of a malignant uterine tumor or massive blood loss after delivery, or because of a congenital disease such as Mayer-Rokitansky-Küster syndrome. UTx has been examined in experimental animals as a basis for establishment of fecundity for young women with uterine factor infertility. In this review, we focus on surrogacy in Japan and UTx research, and discuss the current status and concerns in this field. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

This paper is the primary deliverable of the very first NASA Living With a Star Institute Working Group, Geomagnetically Induced Currents (GIC) Working Group. The paper provides a broad overview of the current status and future challenges pertaining to the science, engineering, and applications of the GIC problem. Science is understood here as the basic space and Earth sciences research that allows improved understanding and physics-based modeling of the physical processes behind GIC. Engineering, in turn, is understood here as the "impact" aspect of GIC. Applications are understood as the models, tools, and activities that can provide actionable information to entities such as power systems operators for mitigating the effects of GIC and government agencies for managing any potential consequences from GIC impact to critical infrastructure. Applications can be considered the ultimate goal of our GIC work. In assessing the status of the field, we quantify the readiness of various applications in the mitigation context. We use the Applications Readiness Level (ARL) concept to carry out the quantification.

There is strong economic evidence to invest in improving the economic status of young children, yet programs remain underresourced. Returns on investment in child nutrition in terms of improved health, better education outcomes and increased productivity are substantial, and cost estimates for effective programs are in the range of $2.8 to $5.3 billion. These amounts are modest when compared with total international development assistance or current spending on luxury goods in wealthy nations. New initiatives to redefine nutrition science and to apply innovative problem-solving technologies to the global nutrition problem suggest that steps are being taken to accelerate progress toward a malnutrition-free world.

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

United States progress in equatorial oceanography is reviewed, focusing on the low frequency response of upper equatorial oceans to forcing by the wind. Variations of thermocline depth, midocean currents, and boundary currents are discussed. The factors which determine sea surface temperature (SST) variability in equatorial oceans are reviewed, and the status of understanding of the most spectacular manifestation of SST variability, the El Nino-Southern Oscillation phenomenon, is discussed. The problem of observing surface winds, regarded as a fundamental factor limiting understanding of the equatorial oceans, is addressed. Finally, an attempt is made to identify those current trends which are expected to bear fruit in the near and distant future.

PREFACE: Inverse Problems in Applied Sciences—towards breakthrough

These are the proceedings of the international conference `Inverse Problems in Applied Sciences—towards breakthrough' which was held at Hokkaido University, Sapporo, Japan on 3-7 July 2006 (http://coe.math.sci.hokudai.ac.jp/sympo/inverse/). There were 88 presentations and more than 100 participants, and we are proud to say that the conference was very successful. Nowadays, many new activities on inverse problems are flourishing at many centers of research around the world, and the conference has successfully gathered a world-wide variety of researchers. We believe that this volume contains not only main papers, but also conveys the general status of current research into inverse problems. This conference was the third biennial international conference on inverse problems, the core of which is the Pan-Pacific Asian area. The purpose of this series of conferences is to establish and develop constant international collaboration, especially among the Pan-Pacific Asian countries, and to lead the organization of activities concerning inverse problems centered in East Asia. The first conference was held at City University of Hong Kong in January 2002 and the second was held at Fudan University in June 2004. Following the preceding two successes, the third conference was organized in order to extend the scope of activities and build useful bridges to the next conference in Seoul in 2008. Therefore this third biennial conference was intended not only to establish collaboration and links between researchers in Asia and leading researchers worldwide in inverse problems but also to nurture interdisciplinary collaboration in theoretical fields such as mathematics, applied fields and evolving aspects of inverse problems. For these purposes, we organized tutorial lectures, serial lectures and a panel discussion as well as conference research presentations. This volume contains three lecture notes from the tutorial and serial lectures, and 22 papers. Especially at this flourishing time, it is necessary to carefully analyse the current status of inverse problems for further development. Thus we have opened with the panel discussion entitled `Future of Inverse Problems' with panelists: Professors J Cheng, H W Engl, V Isakov, R Kress, J-K Seo, G Uhlmann and the commentator: Elaine Longden-Chapman from IOP Publishing. The aims of the panel discussion were to examine the current research status from various viewpoints, to discuss how we can overcome any difficulties and how we can promote young researchers and open new possibilities for inverse problems such as industrial linkages. As one output, the panel discussion has triggered the organization of the Inverse Problems International Association (IPIA) which has led to its first international congress in the summer of 2007. Another remarkable outcome of the conference is, of course, the present volume: this is the very high quality online proceedings volume of Journal of Physics: Conference Series. Readers can see in these proceedings very well written tutorial lecture notes, and very high quality original research and review papers all of which show what was achieved by the time the conference was held. The electronic publication of the proceedings is a new way of publicizing the achievement of the conference. It has the advantage of wide circulation and cost reduction. We believe this is a most efficient method for our needs and purposes. We would like to take this opportunity to acknowledge all the people who helped to organize the conference.

The need for mental health care among children and adolescents in Iran, as in other low and middle income countries (LAMIC) remains mostly unmet. In this paper, we sought to provide an overview of the extent of unmet need and mental health services in Iran. We also aimed to propose approaches to address this gap. We reviewed the published epidemiologic studies of child and adolescent mental and behavioral health problems in Iran. We also examined the current status of child mental health services and the gaps between current needs and available services based on published literature that included papers published in scientific journals, as well as governmental and other administrative reports. The contextual issues relevant to child mental health care were also explored, as well as the possibilities to introduce new or scale up promising services. Child and adolescent mental and behavioral health problems are highly prevalent in Iran. Different studies have estimated that 16.7% to 36.4% of children and adolescents suffer from one or more mental health problems. However, there is a serious scarcity of resources to meet this need. Available services are delivered by independent public organizations (e.g., Ministry of Health, Welfare Organization, and Ministry of Education) or private sector with inefficient communication and collaboration among them and no mandatory national mental health policy. Available specialized child and adolescent services are mostly confined to small inpatient units and university outpatient facilities in larger cities, and there is a scarce evidence for  the effectiveness of the available services. Expansion of primary care's role in timely detection and management of child and adolescent mental health problems, implementation of task-shifting and -sharing initiatives, as well as improved collaboration among responsible governmental and non-governmental sectors are some of the most promising future venues to improve mental health care for the Iranian youth.

Objective We examined the association between methamphetamine (meth) use and dental problems in a large sample of HIV-positive adults. Methods We gathered data from 2,178 interviews across 14 sites of the U.S. Health Resources and Services Administration HIV/AIDS Bureau's Special Projects of National Significance Innovations in Oral Health Care Initiative from May 2007 to August 2010. We used multivariate generalized estimating equations to test the association between meth use and dental problems, adjusting for potential confounders. Results Past and current meth use was significantly associated with more dental problems. The study also found that poor self-reported mental health status, fewer years since testing positive for HIV, a history of forgoing dental care, less frequent teeth brushing, poor self-reported oral health status, oral pain, grinding or clenching teeth, some alcohol use, more years of education, and self-reported men-who-have-sex-with-men HIV risk exposure (compared with other exposure routes) were significantly associated with dental problems. Conclusion Individuals who are HIV-positive with a history of meth use experience access barriers to oral health care and more dental problems. Our study demonstrated that it is possible to recruit this population into dental care. Findings suggest that predisposing, enabling, and need factors can serve as demographic, clinical, and behavioral markers for recruiting people living with HIV/AIDS into oral health programs that can mitigate dental problems.

Opioid dependent patients have legal problems, driving violations and accidents more frequently than the general population. We have hypothesized that those patients currently driving may have better legal outcomes than those who do not possess a valid driving license. With this aim we have analyzed the information gathered in the PROTEUS study regarding the legal and driving statuses and assessed the possible association between them. The PROTEUS study was an observational, cross-sectional, descriptive, multicenter nationwide representative study, conducted in Spanish healthcare centers for opioid dependent patients. The driving and legal statuses of a population of opioid dependent patients ≥ 18 years and enrolled in Opioid Agonist Therapy treatment centers in Spain, were assessed using a short specific questionnaire and the EuropASI questionnaire to highlight distinct individual clinical needs. 621 patients were evaluable (84% men, 24.5% active workers). 321 patients (52%) drove on a regular basis. Nineteen percent of patients had some problem with the criminal justice system. There was a significant difference (p = 0.0433) in status, according to the criminal justice system, between patients who drove on a regular basis and those who did not, with a higher percentage of patients with non-pending charges among usual drivers. Regular drivers showed fewer legal problems than non-regular drivers, with the exception of those related to driving (driving violations and drunk driving). Driving is a good prognostic factor for the social integration of the patients and policies should be implemented to enable these patients to drive safely under medical authorization. The legal description will be useful to assess treatment efficacy.

Objectives Child abuse has negative consequences on health functioning and the self-concept. Prior studies have garnered support for these relationships in younger adults; yet few studies have looked at the effects of abuse on health in older adults and the psychosocial variables, specifically self-efficacy, that may influence the abuse-health relationship. Methods Data obtained from the Physical Health and Disability Study were used to explore the impact of child abuse on current medical problems among older adults who were screened on physical disability status (N=1396, Mean age = 67, SD = 10.2). The study was conducted in South Florida and employed a multiethnic sample that is representative of the general population in this area. Results Child abuse was associated with the number of current medical problems and disability. Child abuse was also related to lower self-efficacy, and self-efficacy explained the relationship between abuse and the number of health problems. Conclusions There are far reaching effects of child abuse on older adults' health and self-concept. Health care providers and gerontologists need to be aware that child abuse is a life-long risk factor for increased disability and specific health problems, especially among the elderly. Future research should examine treatments designed to increase self-efficacy, especially among those who experienced child abuse, and observe any positive effects on health functioning.

Little is known about alcohol misuse and depression among Latino day laborers despite the fact that they encounter multiple stressors (e.g. job instability, unsafe work environments). A structural equation model tested the relationships among laborer stress, social support, health status, current alcohol misuse, and depression. A sample of 89 male, urban Latino day laborers completed measures assessing these constructs in 2011. Stress was negatively related to physical health status, which was associated with depression. Findings suggest that stressors specific to being a day laborer resulting from their work and living conditions generate and maintain health disparities in this vulnerable population. PMID:24779503

Dengue is a significant global health problem. Even though a vaccine against dengue is now available, which is a notable achievement, its long-term protective efficacy against each of the 4 dengue virus serotypes remains to be definitively determined. Consequently, drugs directed at the viral targets or critical host mechanisms that can be used safely as prophylaxis or treatment to effectively ameliorate disease or reduce disease severity and fatalities are still needed to reduce the burden of dengue. This review will provide a brief account of the status of therapeutics research and development for dengue. © The Author 2016.

The impact of prenatal nutritional status, assessed through birth weight (BW) and their effects in the short, medium and long-term on nutritional status, cognitive development and job status in the adult life, has been a problem of interest for several researchers; as regards, some of these report a positive and significant association between these variables and others do not find any relation. Children with insufficient, low or very low BW despite the early more deteriorate nutritional status should present higher risk for brain maturation, failure cognitive development and lowered head circumference which implies both lowered brain volume and intellectual development. In the short and medium-term, this situation damages the learning process at school-age, while in the long-term this might condition the quality of jobs. At present, the body of knowledge pinpoints that findings related to these associations is not conclusive verifying a great controversy in these matters. This review article has the purpose of analyzing the current evidence, in order to stimulate research about to these aspects which are relevant for child development and their future life.

Objective To examine the relationship between menopausal transition status and self-reported sleep difficulty. Methods Using data on women participating in the Medical Research Council National Survey of Health and Development who have been followed up from birth in March 1946 (n = 962), relationships between menopausal transition status and self-reported sleep difficulty were assessed annually between ages 48 – 54. Results Menopausal transition status was related to severe self-reported sleep difficulty. Odds of reporting severe self-reported sleep difficulty were increased approximately 2 to 3.5 fold (95% CI ranges from (1.08, 3.27) – (1.99, 6.04)) for most menopausal transition statuses, compared to women who remained premenopausal. After adjustment for current psychological, vasomotor, and somatic symptoms and waking frequently at night to use the toilet, only women with hysterectomy remained at an increased risk for moderate sleep difficulty. Conclusions The modest relationship between menopausal transition status and moderate sleep difficulty may be related to greater variation in individual definitions of moderate difficulty. Attention to the level of sleep difficulty in this group of women will assist in the decision to address current health symptoms versus sleep itself. Women without prior health problems may experience severe self-reported sleeping difficulty during the menopausal transition and require tailored care from health professionals. PMID:20551846

As a relatively new field of medical science research that has attracted the attention from worldwide researchers, study of digitized virtual human still awaits long-term dedicated effort for its full development. In the full array of research projects of the integrated Virtual Chinese Human project, virtual visible human, virtual physical human, virtual physiome, and intellectualized virtual human must be included as the four essential constitutional opponents. The primary importance should be given to solving the problems concerning the data acquisition for the dataset of this immense project. Currently 9 virtual human datasets have been established worldwide, which are subjected to critical analyses in the paper with special attention given to the problems in the data storage and the techniques employed, for instance, in these datasets. On the basis of current research status of Virtual Chinese Human project, the authors propose some countermeasures for solving the problems in the data acquisition for the dataset, which include (1) giving the priority to the quality control instead of merely racing for quantity and speed, and (2) improving the setting up of the markers specific for the tissues and organs to meet the requirement from information technology, (3) with also attention to the development potential of the dataset which should have explicit pertinence to specific actual applications.

Bipolar disorder-methodological problems and future perspectives

PubMed Central

Angst, Jules

2008-01-01

Since its “rebirth” in 1966, bipolar disorder (BPD) has rapidly come to occupy a central position in the research and treatment of mood disorders. Compared with major depressive disorder (MDD), BPD is a more serious condition, characterized by much more frequent recurrence, more complex comorbidity, and higher mortality. One major problem is the lack of valid definitions in adult and in child psychiatry; the current definitions are unsatisfactory, and heavily favor an overdiagnosis of MDD. Biological research is partially based on those definitions, which have a short half-life. An additional, dimensional, approach, quantifying hypomania, depression, and anxiety by self-assessment and symptom checklists is recommended, A further, related problem is the early recognition of the onset of BPD, especially in adolescence, and the identification of correlates in childhood. Early and timely diagnosis of BPD is necessary to enable prompt intervention and secondary prevention of the disorder. The paper describes the current status and future directions of developing clinical concepts of bipolarity PMID:18689284

Objective This study aimed to summarize the major health problems among Chinese workers, the strategies and measures for occupational hazards control, the network and organizations of occupational health administration, and the achievements and current challenges of occupational health in China. Results The situation of occupational health was found to be still serious in China. Enterprises with occupational hazards were widely distributed, the exposed population and cases of occupational diseases were numerous, and occupational risks were being transferred from the city to the countryside and from developed areas to developing ones. New emerging problems coexisted with traditional occupational hazards. Besides, a lack of occupational health services for migrant workers could be a major problem for a long time. Conclusions It is necessary to improve the fields related to occupational health, such as the supervision and administration of small- and medium-scale enterprises, research into key techniques for the prevention and control of occupational hazards, systems for the diagnosis and reporting of occupational diseases, and the training of health professionals.

On the six Apollo lunar landed missions, the Astronauts deployed the Apollo Lunar Surface Experiments Package (ALSEP) science stations which measured active and passive seismic events, magnetic fields, charged particles, solar wind, heat flow, the diffuse atmosphere, meteorites and their ejecta, lunar dust, etc. Today s investigators are able to extract new information and make new discoveries from the old ALSEP data utilizing recent advances in computer capabilities and new analysis techniques. However, current-day investigators are encountering problems in trying to use the ALSEP data. The data were in formats often not well described in the published reports and contained rerecording anomalies which required tape experts to resolve. To solve these problems the DPS Lunar Data Node was established at NASA Goddard Space Flight Center (GSFC) NASA Space Science Data Center (NSSDC) in 2008 and is currently in the process of making the existing archived ALSEP data available to current-day investigators in easily useable forms. However, current estimates by NSSDC archivists are that only about 60 percent of the PI processed ALSEP data and less than 30 percent of the raw experiment ALSEP data-of-interest to current lunar science investigators are currently in the NSSDC archives.

A systematic review of the interrelation between diet- and surgery-induced weight loss and vitamin D status.

Himbert, Caroline; Ose, Jennifer; Delphan, Mahmoud; Ulrich, Cornelia M

2017-02-01

Obesity is a major global health problem and has been associated with vitamin D deficiency. Intentional weight loss may alter vitamin D status and, conversely, vitamin D supplementation has been hypothesized to aid in weight loss. A systematic literature search in PubMed/Medline identified 3173 articles of which 37 studies (randomized controlled trials (RCT) [n=17], non-RCTs [n=20]) are summarized as effect of: (I) diet-induced weight loss on vitamin D status (n=7), (II) vitamin D supplementation on diet-induced weight loss (n=11), (III) surgery-induced weight loss on vitamin D status (n=15), and (IV) vitamin D supplementation after surgery-induced weight loss on vitamin D status (n=5). While all studies on the effect of diet-induced weight loss on vitamin D status have consistently reported increased vitamin D levels, the targeted percentage of weight loss that is necessary for an increase has varied between 5% and >10%. N=11 RCTs testing the effect of vitamin D supplementation observe that vitamin D supplementation does not result in increased weight loss, but may affect body fat loss. Vitamin D deficiency and subsequent hyperparathyroidism have been detected in post-surgery patients, and there is evidence that vitamin D supplementation improves these post-surgery complications. We review the current evidence addressing the role of vitamin D status and supplementation in diet- and surgery-induced weight loss. Subsequently, we highlight gaps in current research and suggest directions for future research including differences in vitamin D supplementation dosages, indoor vs. outdoor exercise, and the assessment of vitamin D status in different body pools.

Employed women with alcohol problems who seek help from employee assistance programs. Description and comparisons.

1995-01-01

After a brief description of employee assistance programs (EAP), we present data collected from 6,400 employees from 84 worksites who used the services of EAPs, a portion of whom were assessed by the EAP as having alcohol-related problems and/or received scores on the Alcohol Dependence Scale (ADS) indicative of a potential alcohol-related problem. In addition, data were collected at intake from the EAP administrators, and employment status of the employee clients was assessed 18 to 24 months later. These data indicate that EAPs are effective in sustaining the employment of most women with alcohol-related problems who seek services from EAPs and that EAPs' goal of early intervention is especially realized among women with alcohol problems. Other conclusions include: women with alcohol problems do not enter EAPs through routes that are strikingly different from those of men; many of the gender differences that are revealed are associated with job status differences; employed women with alcohol problems are detached from nuclear families, with markedly low rates of current marriage; even when married, spouses are less likely to play a role in the referral of women with alcohol problems than the spouses of the men; and, there is no clear indication that women are the target of any form of discrimination in the process of EAP utilization. However, women are considerably more likely to have less adequate insurance coverage, according to the EAP administrators' assessment reported at client intake, than their male counterparts, leading to treatment choices that may be less than appropriate.

Effect of socioeconomic status on behavioral problems from preschool to early elementary school - A Japanese longitudinal study.

Social inequalities are widely accepted to have a deleterious effect on children's mental health, and those with lower socioeconomic status generally experience more mental health issues. In this study, we examine the impact of socioeconomic situations of children's families during their early childhood on the children's social adaptation in Japanese elementary school. The current investigation consisted of two sets of data relating to two separate years (with a one-year interval). The participants included preschoolers aged five years at Time 1 (the first year) and first graders aged six years at Time 2 (the second year); 1,712 met the inclusion criteria for both years. Parents of the participants completed a self-reported questionnaire regarding their SES (i.e., family economy and mother's education) and their children's mental health. Mental health was assessed using the Child Behavior Checklist/4-18, Parent Report. For each SES indicator, we found an inverse relationship across all the symptom dimensions. Specifically, bivariate analyses revealed that lower family income, maternal education level, and paternal education level predict all three domains of behavioral problems (i.e., internalized problems, externalized problems, and total behavioral problems). Further, multivariate analyses revealed that lower family income consistently predicts all domains of behavioral problems, lower maternal education level predicted externalized problems and total behavioral problems, and paternal education level did not predict any clinically significant behavioral problems. In this sample, we found that, for children, family income and parental education when entering preschool were significant predictors of mental health problems after elementary school enrollment; in particular, low income and low maternal educational achievement predicted a high probability of the development of a psychiatric disorder. A greater understanding of the mechanisms of these associations could contribute to improvements in interventions aimed at preventing child maladjustment.

A typology of childhood problems among chronically homeless adults and its association with housing and clinical outcomes.

2011-08-01

Studies of chronically homeless adults have not adequately investigated the impact of adverse childhood experiences. The current retrospective, longitudinal study profiles the childhood experiences reported by 738 participants in an 11-site supported housing initiative and examines how their childhood profile is related to their homeless history, their psychosocial status before entry into supported housing, and their outcomes once enrolled in supported housing. A two-step cluster analysis revealed three childhood profiles: Relatively Numerous Childhood Problems, Disrupted Family, and Relatively Few Childhood Problems. Results found that participants with Relatively Numerous Childhood Problems were significantly younger when they were first homeless and had worse drug use before entry into supported housing than other participants. There were no differences in housing, substance use, or mental and physical health outcomes once participants were enrolled in supported housing. Prevention of homelessness should focus, to the extent possible, on individuals with extensive childhood problems.

Theoretical models of Kapton heating in solar array geometries

Morton, Thomas L.

1992-01-01

In an effort to understand pyrolysis of Kapton in solar arrays, a computational heat transfer program was developed. This model allows for the different materials and widely divergent length scales of the problem. The present status of the calculation indicates that thin copper traces surrounded by Kapton and carrying large currents can show large temperature increases, but the other configurations seen on solar arrays have adequate heat sinks to prevent substantial heating of the Kapton. Electron currents from the ambient plasma can also contribute to heating of thin traces. Since Kapton is stable at temperatures as high as 600 C, this indicates that it should be suitable for solar array applications. There are indications that the adhesive sued in solar arrays may be a strong contributor to the pyrolysis problem seen in solar array vacuum chamber tests.

2017-11-01

Dehydration in older adults is an important clinical problem associated with more comorbidities, longer hospital stays, and higher mortality rates. However, in daily clinical practice, no single gold standard marker of hydration status in older adults is available. The aim of the current study was to define the fluid balance status in older adults residing in institutional care or the home. Four hundred ten patients (192 from institutional care and 218 from home care) 65 and older from the region of lower Styria (Slovenia) were included in the study. Serum osmolality, electrolytes, and blood urea nitrogen to creatinine (BUN:Cr) ratio were used to identify dehydration. Statistically significant differences were found between groups in serum osmolality and BUN:Cr ratio. Moreover, dehydration (defined as increased serum osmolality) was significantly more common in patients in institutional care than home care (51% versus 41.3%, respectively). The results confirm that dehydration is a common clinical problem in older adults, especially in those from institutional care. Although many methods of determining hydration status in older adults have been proposed, no gold standard exists, making hydration evaluation difficult in this population.

2002-09-01

The aims of this study were to evaluate the oral health status and nutritional status in a group of geriatric rehabilitation patients, and to analyse the relationship between these two parameters. Nurses at the ward performed structured assessments of oral and nutritional status using the Revised Oral Assessment Guide and the Subjective Global Assessment form in 223 newly admitted patients. Most oral health problems were found among patients who stayed longer at the hospital and were more dependent on help as compared with the healthier patients. Thirty-four per cent of the patients were either severely undernourished, at risk or suspected to be undernourished (UN). Oral health problems were more common among UN patients (p < 0.0005) compared with well-nourished patients. The most frequent oral health problem was found on teeth or dentures (48%). Problems related to the tongue and lips were also common among UN patients (56 and 44%, respectively). Oral health status was correlated (r = 0.32) to nutritional status. Problems with swallowing had the strongest association to the nutritional status (OR 6.05; 95% CI 2.41-15.18). This study demonstrated that poor oral health status was related to undernourishment.

Docosahexaenoic acid (DHA, 22:6, n-3) is a long-chain polyunsaturated fatty acid necessary for normal brain growth and cognitive development. Seafood and dietary supplements are the primary dietary sources of DHA. This study addresses the associations between DHA status in pregnant women and healthy, term-born infant problem-solving skills assessed using the Ages and Stages Questionnaire. The fatty acid status of maternal red blood cells (RBCs) was assessed in the 28th week of gestation and at three months postpartum. The infants’ fatty acid status (RBC) was assessed at three, six, and twelve months, and problem-solving skills were assessed at six and twelve months. Maternal DHA status in pregnancy was found to be positively associated with infants’ problem-solving skills at 12 months. This association remained significant even after controlling for the level of maternal education, a surrogate for socio-economic status. The infants’ DHA status at three months was associated with the infants’ problem solving at 12 months. The results accentuate the importance for pregnant and lactating women to have a satisfactory DHA status from dietary intake of seafood or other sources rich in DHA. PMID:29695097

Regression Analysis of a Disease Onset Distribution Using Diagnosis Data

Young, Jessica G.; Jewell, Nicholas P.; Samuels, Steven J.

2008-01-01

Summary We consider methods for estimating the effect of a covariate on a disease onset distribution when the observed data structure consists of right-censored data on diagnosis times and current status data on onset times amongst individuals who have not yet been diagnosed. Dunson and Baird (2001, Biometrics 57, 306–403) approached this problem using maximum likelihood, under the assumption that the ratio of the diagnosis and onset distributions is monotonic nondecreasing. As an alternative, we propose a two-step estimator, an extension of the approach of van der Laan, Jewell, and Petersen (1997, Biometrika 84, 539–554) in the single sample setting, which is computationally much simpler and requires no assumptions on this ratio. A simulation study is performed comparing estimates obtained from these two approaches, as well as that from a standard current status analysis that ignores diagnosis data. Results indicate that the Dunson and Baird estimator outperforms the two-step estimator when the monotonicity assumption holds, but the reverse is true when the assumption fails. The simple current status estimator loses only a small amount of precision in comparison to the two-step procedure but requires monitoring time information for all individuals. In the data that motivated this work, a study of uterine fibroids and chemical exposure to dioxin, the monotonicity assumption is seen to fail. Here, the two-step and current status estimators both show no significant association between the level of dioxin exposure and the hazard for onset of uterine fibroids; the two-step estimator of the relative hazard associated with increasing levels of exposure has the least estimated variance amongst the three estimators considered.

The microbial degradation of nitrogen compounds from fossil fuels is important because of the contribution these contaminants make to the formation of nitrogen oxides (NOx) and hence to air pollution and acid rain. They also contribute to catalyst poisoning during the refining of crude oil, thus reducing process yields. We review the current status of microbial degradation of aromatic nitrogen compounds and discuss the potential of microbial processes to alleviate these problems.

Intellectual disability and homelessness.

Mercier, C; Picard, S

2011-04-01

The association between poverty and intellectual disability (ID) has been well documented. However, little is known about persons with ID who face circumstances of extreme poverty, such as homelessness. This paper describes the situation of persons with ID who were or are homeless in Montreal and are currently receiving services from a team dedicated to homeless persons. (1) To describe the characteristics, history and current situation of these persons; and (2) to report within-group differences as a function of gender and current residential status. The data were collected from files using an anonymous chart summary. Descriptive statistics on the whole sample (n = 68) and inferential statistics on cross-tabulations by gender and residential status were performed. Persons with ID exhibited several related problems. Some of these persons, primarily women, experienced relatively short periods of homelessness and their situations stabilised once they were identified and followed up. Other persons with ID experienced chronic homelessness that appeared to parallel the number and severity of their other problems. When compared with a previous epidemiological study of the homeless in Montreal, the population of homeless persons with ID differed from the overall homeless population in a number of respects. The results suggest prevention and intervention targets. The need for epidemiological research appears particularly clear in light of the fact that below-average intellectual functioning has been identified as a risk factor for homelessness and a predisposing factor for vulnerability among street people. © 2011 The Authors.

The developmental adaptation model (Martin & Martin, 2002) provides insights into how current experiences and resources (proximal variables) and past experiences (distal variables) are correlated with outcomes (e.g., well-being) in later life. Applying this model, the current study examined proximal and distal variables associated with positive and negative affect in oldest-old adults, investigating age differences. Data from 306 octogenarians and centenarians who participated in Phase III of the Georgia Centenarian Study were used. Proximal variables included physical functioning, cognitive functioning, self-rated health, number of chronic conditions, social resources, and perceived economic status; distal variables included education, social productive activities, management of personal assets, and other learning experiences. Analysis of variance and block-wise regression analyses were conducted. Octogenarians showed significantly higher levels of positive emotion than centenarians. Cognitive functioning was significantly associated with positive affect, and number of health problems was significantly associated with negative affect after controlling for gender, ethnicity, residence, and marital status. Furthermore, four significant interaction effects suggested that positive affect significantly depended on the levels of cognitive and physical functioning among centenarians, whereas positive affect was dependent on the levels of physical health problems and learning experiences among octogenarians. Findings of this study addressed the importance of current and past experiences and resources in subjective well-being among oldest-old adults as a life-long process. Mechanisms connecting aging processes at the end of a long life to subjective well-being should be explored in future studies.

Energy demand in Malaysia is increasing over seven per cent a year, while forty per cent of the energy is supplied from conventional fossil fuel. However, a number of social barriers have mired the social acceptance of renewable energy among the users. This study investigates the current status of renewable energy, problems and future outlook of renewable energy in Malaysia. A total of 200 respondents were surveyed from Klang Valley in Malaysia. Majority of the respondents use energy to generate electricity. Although some respondents reported using solar energy, there is lack of retail availability for solar energy. The findings show that limited information on renewable energy technologies, lack of awareness, and limited private sector engagement emerged as major barriers to sustainable renewable energy development. In addition, the respondents suggest for increasing policy support from the government to make information more accessible to mass users, provide economic incentives to investors and users, and promote small-community based renewable energy projects. The study suggests that the government begin small scale projects to build awareness on renewable energy, while academically, higher learning institutions include renewable energy syllabus in their academic curriculum. The study concluded that to have sustainable renewable energy development, government's initiative, private sector engagement and users awareness must be given priority.

There is a dearth of research examining the health correlates of tobacco use within the homeless population, particularly with respect to homeless Veterans. An aim of the present study was to compare homeless Veteran and homeless non-Veteran smokers across a series of socio-demographic and health variables, and to determine whether any of these variables were independently associated with Veteran status. A subsequent aim was to compare the socio-demographic and health profiles of Veteran smokers and Veteran nonsmokers, and to determine whether any of these variables were independently associated with current smoking. Data were obtained from the 2009 Homelessness in Minnesota survey conducted by the Wilder Research Foundation. The final sample included 4750 homeless individuals living throughout Minnesota. The prevalence of smoking was greater among homeless Veterans (74%) than homeless non-Veterans (70%). The prevalence of physical and mental health problems was higher among homeless Veteran smokers than homeless non-Veteran smokers, although these variables were not independently associated with Veteran status after controlling for socio-demographics. Analyses of the homeless Veteran sample indicated that receipt of Veterans' benefits, type of discharge, and alcohol and/or chemical dependence were independently associated with current smoking. Homeless Veteran smokers exhibit heightened rates of physical and mental health problems compared to homeless non-Veteran smokers. Military service and discharge characteristics may contribute to this high smoking prevalence. Future efforts should focus on increasing Veterans' access to and knowledge of Veterans' health resources, and on developing innovative strategies to boost cessation in this population.

Hernia is a common problem of the modern world with its incidence more in developing countries. Inguinal hernia is the most common groin hernia repaired worldwide. With advancement in technology operative techniques of repair have also evolved. A PubMed and COCHRANE database search was accomplished in this regard to establish the current status of laparoscopic inguinal hernia repair in view of recent published literature. Published literature support that laparoscopic hernia repair is best suited for recurrent and bilateral inguinal hernia although it may be offered for primary inguinal hernia if expertise is available.

Reese, Jennifer Barsky; Haythornthwaite, Jennifer A

The primary objectives were (1) to examine the importance of sexuality within the self-view and cross-sectional correlates for 120 colorectal cancer patients and (2) to determine whether the importance of sexuality changed for 46 colorectal cancer patients and partners participating in an intimacy enhancement intervention. Two newly developed items assessed importance of sexuality within the self-view (1) currently and (2) before cancer; a calculated change score assessed perceived change. In the cross-sectional sample, associations between importance of sexuality and demographic and medical factors and sexual function status were examined. Intervention participants' importance ratings before and after participation were used to calculate effect sizes. For patients, importance of sexuality before cancer was greater (M = 65.7) than current importance (M = 56.8, p = .001). Greater current importance of sexuality was associated with partnered status, non-metastatic disease, and not being in treatment. Scoring in the sexually functional range was associated with greater current importance of sexuality for men and a smaller perceived change in importance for both men and women (p values <.05). Sexual function status also significantly predicted current importance independent of covariates. Small to medium effect sizes for intervention patients (.37) and partners (.60) were found for increases in importance of sexuality. Items showed evidence of test-retest reliability and construct validity. Coping with sexual concerns is important to those affected by colorectal cancer. Findings suggest that the importance of sexuality can decrease through colorectal cancer and associated sexual problems and can increase through participating in an intimacy-focused intervention.

1. Medical undergraduate education is currently undergoing major changes in the UK in response to calls for the development of a core curriculum. Teaching in clinical pharmacology and therapeutics will also change to meet these demands. A postal survey was conducted to assess the current status of teaching in these subjects. 2. A questionnaire based on previous similar surveys conducted elsewhere was sent to departments or individuals in 27 medical schools in the UK; 22 (81%) replied. 3. Departmental priorities were defined as (in order): clinical research, undergraduate teaching, basic scientific research and clinical service provision. No change in these priorities in the future was foreseen by respondents. 4. Teaching methods were for the most part traditional, with the lecture as the most widely used and important technique. Specific clinical teaching was conducted by some and was considered very important by them. Teaching by problem solving was much less common. 5. Respondents were asked for free text comments; many of the remarks suggested dissatisfaction with the resources and time currently available for teaching in clinical pharmacology and therapeutics. Some expressed significant concerns that their teaching commitment would be reduced further by the development of the core curriculum. PMID:8186059

Background and aims Familial influences are known to affect the likelihood of an adolescent becoming a problem gamer. This systematic review examined some of the key findings in empirical research on family factors related to adolescent problem gaming. Methods A total of 14 studies in the past decade were evaluated. Family-related variables included: (a) parent status (e.g., socioeconomic status and mental health), (b) parent-child relationship (e.g., warmth, conflict, and abuse), (c) parental influence on gaming (e.g., supervision of gaming, modeling, and attitudes toward gaming), and (d) family environment (e.g., household composition). Results The majority of studies have focused on parent-child relationships, reporting that poorer quality relationships are associated with increased severity of problem gaming. The paternal relationship may be protective against problem gaming; therefore, prevention programs should leverage the support of cooperative fathers. Discussion The intergenerational effects of problem gaming require further attention, in light of adult gamers raising their children in a gaming-centric environment. Research has been limited by a reliance on adolescent self-report to understand family dynamics, without gathering corroborating information from parents and other family members. The very high rates of problem gaming (>10%) reported in general population samples raise concerns about the validity of current screening tools. Conclusions Interventions for adolescents may be more effective in some cases if they can address familial influences on problem gaming with the active co-participation of parents, rather than enrolling vulnerable adolescents in individual-based training or temporarily isolating adolescents from the family system.

Bioinorganic modeling chemistry of carbon monoxide dehydrogenases: description of model complexes, current status and possible future scopes.

PubMed

Majumdar, Amit

2014-08-28

Carbon monoxide dehydrogenases (CODHs) use CO as their sole source of carbon and energy and are found in both aerobic and anaerobic carboxidotrophic bacteria. Reversible transformation of CO to CO2 is catalyzed by a bimetallic [Mo-(μ2-S)-Cu] system in aerobic and by a highly asymmetric [Ni-Fe-S] cluster in anaerobic CODH active sites. The CODH activity in the microorganisms effects the removal of almost 10(8) tons of CO annually from the lower atmosphere and earth and thus help to maintain a sub-toxic concentration of CO. Despite an appreciable amount of work, the mechanism of CODH activity is not clearly understood yet. Moreover, biomimetic chemistry directed towards the active sites of CODHs faces several synthetic challenges. The synthetic problems associated with the modeling chemistry and strategies adopted to overcome those problems are discussed along with their limitations. A critical analysis of the exciting results delineating the present status of CODH modeling chemistry and its future prospects are presented.

Child soldiers often experience complex trauma as victims and perpetrators, and feelings of guilt may affect their psychological health. The relationship between the children's traumatic experiences as victims or perpetrators, their perception of themselves as victim or perpetrator, guilt and psychopathology were investigated: of the 330 former child soldiers interviewed, 50.8 % perceived themselves as victims and 19.1 % as perpetrators. On psychopathology measures, scores within the clinical range were 33 % for posttraumatic stress disorder (PTSD), 36.4 % for major depressive disorder (MDD), and 26.1 % for externalizing problems. Low socio-economic status, traumatic experience as perpetrator, and guilt were significant predictors of PTSD. Significant predictors of MDD were low socio-economic status, traumatic experiences as victim, and guilt. A greater number of traumatic experiences as perpetrator and guilt were associated with externalizing problems. The current paper underscores the significance of guilt following traumatic experiences and has implications for the development of clinical interventions for war-affected children.

Abstract Pangolins are unique placental mammals with eight species existing in the world, which have adapted to a highly specialized diet of ants and termites, and are of significance in the control of forest termite disaster. Besides their ecological value, pangolins are extremely important economic animals with the value as medicine and food. At present, illegal hunting and habitat destruction have drastically decreased the wild population of pangolins, pushing them to the edge of extinction. Captive breeding is an important way to protect these species, but because of pangolin’s specialized behaviors and high dependence on natural ecosystem, there still exist many technical barriers to successful captive breeding programs. In this paper, based on the literatures and our practical experience, we reviewed the status and existing problems in captive breeding of pangolins, including four aspects, the naturalistic habitat, dietary husbandry, reproduction and disease control. Some recommendations are presented for effective captive breeding and protection of pangolins. PMID:26155072

Recent guidelines have encouraged gastroenterology and surgical training programs to integrate simulation into their core endoscopic curricula. However, the role that simulation currently has within training programs is unknown. This study aims to assess the current status of simulation among gastroenterology fellowship programs. This questionnaire study consisted of 38 fields divided into two sections. The first section queried program directors' experience on simulation and assessed the current status of simulation at their institution. The second portion surveyed their opinion on the potential role of simulation on the training curriculum. The study was conducted at the 2013 American Gastroenterological Association Training Directors' Workshop in Phoenix, Arizona. The participants were program directors from Accreditation Council for Graduate Medical Education accredited gastroenterology training programs, who attended the workshop. The questionnaire was returned by 69 of 97 program directors (response rate of 71%). 42% of programs had an endoscopic simulator. Computerized simulators (61.5%) were the most common, followed by mechanical (30.8%) and animal tissue (7.7%) simulators, respectively. Eleven programs (15%) required fellows to use simulation prior to clinical cases. Only one program has a minimum number of hours fellows have to participate in simulation training. Current simulators are deemed as easy to use (76%) and good educational tools (65%). Problems are cost (72%) and accessibility (69%). The majority of program directors believe that there is a need for endoscopic simulator training, with only 8% disagreeing. Additionally, a majority believe there is a role for simulation prior to initiation of clinical cases with 15% disagreeing. Gastroenterology fellowship program directors widely recognize the importance of simulation. Nevertheless, simulation is used by only 42% of programs and only 15% of programs require that trainees use simulation prior to clinical cases. No programs currently use simulation as part of the evaluation process.

This study investigates the impact of HIV diagnosis on subjective social status and if changes are linked to health outcomes. Two measures of subjective social status, socio-economic and standing in the community were examined in 342 Australian HIV-positive gay men in 2014. Participants recalled ratings at diagnosis were compared with current ratings. Self-reported mental (psychological distress, self-esteem, positive mental health and satisfaction with life) and physical health (self-rated health, CD4 count, viral load). Half of the participants reported improvements in subjective socio-economic status (59%) or standing in the community (52%) since diagnosis, yet one quarter reported socio-economic status (25%) or standing in the community had decreased (23%). Increases in either measure of subjective social status were linked to higher self-esteem, positive mental health, satisfaction with life and better self-rated health. Decreases in subjective social status, however, were strongly linked to poorer outcomes on all mental health measures. Decreases in standing in the community were also associated with poorer physical self-rated health. Most participants reported their subjective social status were the same or better since diagnosis. Changes in subjective social status following diagnosis were strongly linked to mental health outcomes. Those who reported a decrease in subjective social status were particularly vulnerable to mental health problems.

All helping professionals risk participation in "dual relationships." But in the case of former substance users working as counselors, specific dilemmas and problems are accentuated. A qualitative analysis highlights some of the ethical and personal dilemmas faced by these counselors. The data are derived from an interview study initiated in 2000 in Denmark on former substance users with 4-8 years of abstinence. Through an analysis of interview data from a larger group of former substance users, it became evident that those working as counselors experienced specific dilemmas and problems. The current article is based on individual reports of five counselors with recovery status.

Smoking has always been a huge problem in Malaysia and its surrounding nations. The purpose of this study was to determine the prevalence of cigarette smoking and to identify the influencing factors associated with smoking habits among adolescents. This cross-sectional study was carried out on 226 respondents, using a questionnaire which had 4 sections: socio-demographic data, personal information, family information and social information. Data was analyzed using SPSS® version 16. For categorical variables, comparisons were made using Chi-square and for numerical variables a t-test was performed. The current smoker prevalence rate was 20.8% which showed a significant association between smoking and individual factors: level of knowledge on the effects of smoking (p < 0.05), significant association was seen between smoking and marital status of parents, smoking status of male siblings and various other aspects of the individuals themselves. Concerted efforts involving various parties should be taken to curb or prevent this problem or the number of teenage smokers in the country will increase. This in the long run will invite problems to the well being of the adolescents themselves, their families, community and the nation as a whole.

The purpose of this research was to expand knowledge in the current literature regarding treatment retention in intensive outpatient substance abuse treatment programs. The sample in this study participated in a hospital-based program accredited by the Joint Commission on Accreditation for Health Organizations (JCAHO) that utilized the Minnesota model. Specifically, this inquiry investigated whether treatment retention would be predicted by gender, age, employment status, number of problems on the treatment plan, whether the referral was related to driving while intoxicated (DWI), marital status, race, and whether each of the following substance problems was listed as the client's primary DSM-IV diagnosis: alcohol dependence, cocaine dependence, polysubstance dependence, opioid dependence, sedative/hypnotic dependence, cannabis dependence, other (or unknown) dependence, alcohol abuse, cannabis abuse, amphetamine abuse, and caffeine intoxication. Findings indicated that those retained in treatment, when compared to those who dropped out, had significantly more problems on their treatment plans, were more likely to be alcoholics, were less often cocaine addicts, and were more likely to be employed. The results of this study suggest that clients with this profile have increased likelihood of being retained in intensive outpatient substance abuse treatment programs.

In Crohn disease, bowel-preserving surgery is necessary to prevent short bowel syndrome due to repeated operations. This study aimed to determine the remnant small bowel length cut-off and to evaluate the clinical factors related to nutritional status after small bowel resection in Crohn disease.We included 394 patients (69.3% male) who underwent small bowel resection for Crohn disease between 1991 and 2012. Patients who were classified as underweight (body mass index < 17.5) or at high risk of nutrition-related problems (modified nutritional risk index < 83.5) were regarded as having a poor nutritional status. Preliminary remnant small bowel length cut-offs were determined using receiver operating characteristic curves. Variables associated with poor nutritional status were assessed retrospectively using Student t tests, chi-squared tests, Fisher exact tests, and logistic regression analyses.The mean follow-up period was 52.9 months and the mean patient ages at the time of the last bowel surgery and last follow-up were 31.2 and 35.7 years, respectively. The mean remnant small bowel length was 331.8 cm. Forty-three patients (10.9%) underwent ileostomy, 309 (78.4%) underwent combined small bowel and colon resection, 111 (28.2%) had currently active disease, and 105 (26.6%) underwent at least 2 operations for recurrent disease. The mean body mass index and modified nutritional risk index were 20.6 and 100.8, respectively. The independent factors affecting underweight status were remnant small bowel length ≤240 cm (odds ratio: 4.84, P < 0.001), ileostomy (odds ratio: 4.70, P < 0.001), and currently active disease (odds ratio: 4.16, P < 0.001). The independent factors affecting high nutritional risk were remnant small bowel length ≤230 cm (odds ratio: 2.84, P = 0.012), presence of ileostomy (odds ratio: 3.36, P = 0.025), and currently active disease (odds ratio: 4.90, P < 0.001).Currently active disease, ileostomy, and remnant small bowel length ≤230 cm are risk factors affecting the poor nutritional status of patients with Crohn disease after small bowel resection.

There has been a great deal of research on the comorbidity of insomnia and psychiatric disorders, but much of the existing data is based on small samples and does not assess the full diagnostic criteria for each disorder. Further, the exact nature of the relationship between these conditions and their impact on cognitive problems are under-researched in military samples. Data were collected from the All Army Study of the Army Study to Assess Risk and Resilience in Service members (unweighted N = 21, 449; weighted N = 674,335; 18-61 years; 13.5% female). Participants completed the Brief Insomnia Questionnaire to assess for insomnia disorder and a self-administered version of the Composite International Diagnostic Interview Screening Scales to assess for psychiatric disorders and cognitive problems. Military soldiers with current major depressive episode (MDE) had the highest prevalence of insomnia disorder (INS; 85.0%), followed by current generalized anxiety disorder (GAD; 82.6%) and current posttraumatic stress disorder (PTSD; 69.7%), respectively. Significant interactions were found between insomnia and psychiatric disorders; specifically, MDE, PTSD, and GAD status influenced the relationship between insomnia and memory/concentration problems. Cross-sectional nature of the assessment and the absence of a comprehensive neurocognitive battery. Psychiatric disorders moderated the relationship between insomnia and memory/concentration problems, suggesting that psychiatric disorders contribute unique variance to cognitive problems even though they are associated with insomnia disorder. Results highlight the importance of considering both insomnia and psychiatric disorders in the diagnosis and treatment of cognitive deficits in military soldiers. Copyright © 2017 Elsevier B.V.

2008-12-01

Reasons for quitting smoking and triggers that finally precipitate a quit attempt are not necessarily the same thing. We sought to assess variation in reported triggers of attempts to stop smoking as a function of age, gender and socioeconomic status. Cross-sectional household survey in England. A total of 2441 smokers and ex-smokers aged 16 and over, who reported making at least one serious quit attempt in the last 12 months, were recruited. The main outcome measure was participants' responses to the question "What finally triggered your most recent quit attempt?". Respondents selected from a list of options or specified a trigger not on the list. In the event, smokers typically reported as triggers similar factors as have previously been reported as "reasons". "A concern about future health problems" (28.5%) was the most commonly cited trigger followed by "health problems I had at the time" (18%) and then "a decision that smoking was too expensive" (12.2%). The most common external trigger was advice from a health professional (5.6%). Future health concern was more common in smokers with higher socioeconomic status (SES), whereas cost and current health problems were more often cited by lower SES smokers. Younger smokers were more likely to report their quit attempt being triggered by a TV advertisement while older smokers were more likely to cite advice from a health professional. Concern about future health problems was cited less often by 16 to 24 year olds and those aged 65+ than those aged 25 to 64 years. There are significant differences in reported triggers for quit attempts as a function of sociodemographic factors. Most notably, smokers with higher SES are more likely to report concern about future health whereas those from lower SES are more likely to cite cost and current health problems.

In Europe, the prevalence of gambling disorders in the general population ranges from 0.15 to 6.6%. Professional athletes are known for having risk factors for addictive behaviors, such as young age or sensation seeking, though no study has yet tried to evaluate the prevalence of gambling and gambling disorders among this specific population. The goals of this study were to estimate the prevalence of gambling, problematic or not, among European professional athletes and to explore the factors that are associated with gambling practice and gambling problems in professional athletes. A self-completion questionnaire was specifically designed for this study. The questionnaires were distributed by European Union athletes to professional ice hockey, rugby, handball, basketball, football, indoor football, volleyball, and cricket teams in Spain, France, Greece, Ireland, Italy, Sweden, and the United Kingdom. Socio-demographic variables (age, sex, education, marital and parental status, sport, country of birth, and country of practice), variables linked to gambling (gambling habits, screening of gambling problems with the Lie/Bet questionnaire, and gambling related cognitions), and impulsive behavior data (urgency, premeditation, perseverance, and sensation seeking [UPPS]-Short Form questionnaire) were gathered. There were 1,236 questionnaires filled out. The percentage of professional athletes that had gambled at least once during the previous year was 56.6%. The prevalence of problem gambling, current or past, was 8.2%. A certain number of variables were associated with the gambling status.

This paper focused on a system for tracking the status of the paperwork using the Near Field Communication (NFC) technology and mobile apps. Student paperwork tracking system or known as SPATRASE was developed to ease the user to track the location status of the paperwork. The current problem faced by the user is the process of approval paperwork takes around a month or more. The process took around a month to get full approval from the department because of many procedures that need to be done. Nevertheless, the user cannot know the location status of the paperwork immediately because of the inefficient manual system. The submitter needs to call the student affairs department to get the information about the location status of the paperwork. Thus, this project was purposed as an alternative to solve the waiting time of the paperwork location status. The prototype of this system involved the hardware and software. The project consists of NFC tags, RFID Reader, and mobile apps. At each checkpoint, the RFID Reader was placed on the secretary desk. While the system involved the development of database using Google Docs that linked to the web server. After that, the submitter received the URL link and be directed to the web server and mobile apps. This system is capable of checking their location status tracking using mobile apps and Google Docs. With this system, it makes the tracking process become efficient and reliable to know the paperwork at the exact location. Thus, it is preventing the submitter to call the department all the time. Generally, this project is fully functional and we hope it can help Universiti Tun Hussein Onn Malaysia (UTHM) to overcome the problem of paperwork missing and location of the paperwork.

To evaluate caregiver burden and factors that influence this burden among caregivers and patients with Alzheimer's disease in China. Long-term care can reduce the quality of life for caregivers and result in both mental and physical exhaustion. However, little is known about caregiver burden and associated factors in China. The study had a quantitative cross-sectional design. A total of 309 caregivers and their patients were included in the study. The patients' cognitive, psychological and functional status and their caregivers' burden, sleep quality and mental state were evaluated. Descriptive analyses, single-factor regression and stepwise factor regression were used to determine the effects of various factors on caregiver burden. Older females and spouses still play an important role in providing family care for those with dementia. Most of the caregivers were the sole full-time caregiver and had little time for themselves. Sleepiness was a common physical problem for caregivers, and some of them had moderate to severe depression and anxiety. A lower functional status of the patient was associated with higher caregiver burden. Poorer physical status compared with before caregiving began, lower life satisfaction, and higher degrees of depression and anxiety were associated with higher caregiver burden. Depression, anxiety and sleep problems are the main challenges that are faced by family caregivers of patients with Alzheimer's disease. Caregivers' functional status, lower life satisfaction, depression and anxiety influenced caregiver burden. Caregiver burden was related to the severity of the patient's dementia and the personal factors of the caregivers. To provide information about caregivers' current status while caring for patients with Alzheimer's disease and to understand caregiver burden and its related factors. Professionals who work with Alzheimer's disease should pay more attention to caregiver burden, especially those with mental and physical problems. © 2016 John Wiley & Sons Ltd.

A meeting on Marine Biomedical Research, sponsored by the National Institute of Environmental Health Sciences (NIEHS), National Institutes of Health and the Smithsonian Institution Museum of Natural History, was attended by approximately 125 scientists, directors and representatives from many of the country's marine biological laboratories, and government agencies whose interests and responsibilites are in the marine biology and health areas. The purpose of the meeting was to explore the undeveloped research opportunities in the area of marine biology for the advancement of our understanding of human health problems and to provide information on the current status of marine biology laboratories. The meeting was devoted to presentations and discussions in four general areas: (1)Marine Species as Models for Human Disease; (2)Environmental Carcinogenesis and Mutagenesis; (3)Human Health and the Marine Environment--infectious agents and naturally occurring and foreign toxins; and (4)Drugs from the seas. Representatives from twelve of the country's approximatley 40 marine laboratories discussed their organization, developmental history, scientific programs, facilities, and present status of their support. The presentations served as a background and stimulated very lively analytical and constructive discussions of the undeveloped research and education potential residing in the marine environment and biological laboratories for a better understanding of many human health problems; some scientific areas that should be developed to realize this potential; and the needs and problems of marine laboratories that require attention and support if they are to survive and realize their possibilities.

Current Status of Mycotoxin Analysis: A Critical Review.

PubMed

Shephard, Gordon S

2016-07-01

It is over 50 years since the discovery of aflatoxins focused the attention of food safety specialists on fungal toxins in the feed and food supply. Since then, analysis of this important group of natural contaminants has advanced in parallel with general developments in analytical science, and current MS methods are capable of simultaneously analyzing hundreds of compounds, including mycotoxins, pesticides, and drugs. This profusion of data may advance our understanding of human exposure, yet constitutes an interpretive challenge to toxicologists and food safety regulators. Despite these advances in analytical science, the basic problem of the extreme heterogeneity of mycotoxin contamination, although now well understood, cannot be circumvented. The real health challenges posed by mycotoxin exposure occur in the developing world, especially among small-scale and subsistence farmers. Addressing these problems requires innovative approaches in which analytical science must also play a role in providing suitable out-of-laboratory analytical techniques.

Introduction: Suicide is one of the most prominent problems in health care system in current Iran. It could be impacted by various factors such as social, economic, individual and so on. Researchers show that socio-economic factors and suicide has significantly related. The people in low social class may more engage with social problems than higher social class. They may confront to problems such as crime, violence, unemployment, financial hardship, population density, disorder personality, etc. However, these difficulties could be resulted from relationship of inequality socio-economic and mental or physical health. This research attempted to examine social class status and its relationship with parts of suicide characteristics. Methods: This study applied a descriptive approach. In the cross-sectional research 179 patients who attempted suicide and admitted to the toxicology ward of Nour hospital and to the burning ward of Imam Mousa Kazem hospital, in Isfahan, during a period of 6 months in 2010 were recruited. The randomize sampling for patients admitted to toxicology ward and census for burning ward are applied. Data collected through a questionnaire which Chronbagh coefficient’s alpha was calculated (r= 0/72). Data was analyzed in SPSS software. Findings: The data showed that the majority of patients who attempted suicide were young married women who had diploma and under diploma of level education. They were housewife, engaged in education and unemployment. Finding showed that there are no significant relationships between sex, age, marital status, frequency of attempted suicide and their social class. But there is significant relationship between methods of suicide and social class. Similarly, there are significant relationship between social factors (i.e. family friction, betrothal, unemployment, financial problems and so on) effected on suicide and their social classes. Parts of findings were supported by previous studies. PMID:23687462

Feeding difficulties are frequent in children with neurological impairments and can be associated with undernutrition, growth failure, micronutrients deficiencies, osteopenia, and nutritional comorbidities. Gastrointestinal problems including gastroesophageal reflux disease, constipation, and dysphagia are also frequent in this population and affect quality of life and nutritional status. There is currently a lack of a systematic approach to the care of these patients. With this report, European Society of Gastroenterology, Hepatology and Nutrition aims to develop uniform guidelines for the management of the gastroenterological and nutritional problems in children with neurological impairment. Thirty-one clinical questions addressing the diagnosis, treatment, and prognosis of common gastrointestinal and nutritional problems in neurological impaired children were formulated. Questions aimed to assess the nutritional management including nutritional status, identifying undernutrition, monitoring nutritional status, and defining nutritional requirements; to classify gastrointestinal issues including oropharyngeal dysfunctions, motor and sensory function, gastroesophageal reflux disease, and constipation; to evaluate the indications for nutritional rehabilitation including enteral feeding and percutaneous gastrostomy/jejunostomy; to define indications for surgical interventions (eg, Nissen Fundoplication, esophagogastric disconnection); and finally to consider ethical issues related to digestive and nutritional problems in the severely neurologically impaired children. A systematic literature search was performed from 1980 to October 2015 using MEDLINE. The approach of the Grading of Recommendations Assessment, Development, and Evaluation was applied to evaluate the outcomes. During 2 consensus meetings, all recommendations were discussed and finalized. The group members voted on each recommendation using the nominal voting technique. Expert opinion was applied to support the recommendations where no randomized controlled trials were available.

　While the community-based integrated care systems are in the process of being structured currently, more and more community pharmacists want to learn physical assessment skills. However, no large-scale survey focusing on present implementation status and problems of physical assessment by community pharmacists has been conducted yet. Osaka has the 2nd highest number of community pharmacies in Japan now, and the population aged ≥65 years will be expected to become the 3rd highest in 2025. Thus, Osaka can become a national leading model case for community pharmacists' activity in future home medical care. Therefore, this study aimed to reveal the present implementation status and problems of physical assessment by community pharmacists in Osaka, especially focusing on vital-signs. The questionnaires were sent to all the 3571 insurance pharmacies belonging to the Osaka Pharmaceutical Association and 871 pharmacies responded. Many pharmacists recognized the necessity for vital-signs measurement by pharmacists in home medical care (81.5% of pharmacies that offered home medical care and 75.4% of pharmacies that did not offer one). However, the proportion of pharmacies that conduct vital-signs measurement in home medical care was 18.7%, therefore, it was suggested that the present problem is "many pharmacists cannot conduct vital-signs measurement, although they think it should be conducted". Moreover, the most common reason for not measuring vital-signs was the lack of instruments, such as stethoscopes and sphygmomanometer (43.2%). This is the latest report with a large-scale sample, thus, it can serve as valuable knowledge in considering what pharmacists do for the future.

As one kind of most crucial and emerging lead-free piezoelectric systems, Ba(Ti0.8Zr0.2)O3-(Ba0.7Ca0.3)TiO3 (BCZT) based lead-free piezoceramics have attracted worldwide attention in recent years. Much progress has been made, however, a summary which covers both the recent progress and the remained problems is urgently needed to further push this field forward. In this review, a brief background of the development of BCZT based lead-free piezoceramics was illustrated firstly. Then, the internal mechanism for the high piezoelectric response would be elaborated. Current research status was discussed in detail in the third section. Various strategies including: (1) Using distinct synthesis routes, (2) adopting different sintering techniques, (3) doping with foreign ions and/or second components, (4) grain size control, were exploited to improve the comprehensive performance and in turn broaden their application areas. In this part, some recently representative works were touched in detail and several existing problems were pointed out. Last, some critical comments (some thoughts related to the potential and future development of BCZT system) were given based on the current research status and existing problems. All in all, this review is devoted to summarizing the milestones in the past, classifying selected recent works and analyzing the prospects of BCZT based ceramics. It can be expected that, this first review that concentrates on BCZT based ceramics obviously would provide useful guidance for the research community.

Mayas, having experienced genocide, exile, and severe poverty, are at high risk for the consequences of cumulative trauma that continually resurfaces through current fear of an uncertain future. Little is known about the mental health and alcohol use status of this population. This correlational study explored t/he relationship of cumulative trauma as it relates to social determinants of health (years in the United States, education, health insurance status, marital status, and employment), psychological health (depression symptoms), and health behaviors (alcohol use) of 102 Guatemalan Mayas living in Southeast Florida. The results of this study indicated that, as specific social determinants of health and cumulative trauma increased, depression symptoms (particularly among women) and the risk for harmful alcohol use (particularly among men) increased. Identifying risk factors at an early stage before serious disease or problems are manifest provides room for early screening leading to early identification, early treatment, and better outcomes.

1999-04-01

Interviews were conducted with 294 black residents (155 females and 138 males) of a peri-urban informal settlement in Gauteng to ascertain utilisation of oral health services, oral health needs and oral health status. Only 37 per cent of the sample had consulted a dentist or medical practitioner, usually for extractions. Teenagers and employed persons were significantly less likely to utilise dentists than the older age groups and unemployed persons. Forty per cent were currently experiencing oral health problems such as a sore mouth, tooth decay and bleeding/painful gums. Two hundred and twelve (73 per cent) interviewees wanted dental treatment or advice. Residents who rated their oral health status as fair or poor appeared to have the greatest need for oral health services. The use of interviews appears to be a cost-effective method of determining oral morbidity.

Objectives To investigate the relations among hot flashes, other menopausal symptoms, sleep quality and depressive symptoms in midlife women Methods A large population-based cross-sectional study of 639 women (ages 45 to 54 years) consisting of a questionnaire including the Center for Epidemiologic Studies-Depression Scale (CES-D), demographics, health behaviors, menstrual history, and menopausal symptoms Results After controlling for menopausal status, physical activity level, smoking status and current self-reported health status elevated CES-D score is associated with frequent nocturnal hot flashes, frequent trouble sleeping, experiencing hot flashes, nausea, headaches, weakness, visual problems, vaginal discharge, irritability, muscle stiffness, and incontinence. Conclusions The present study found significant links between depressive symptoms and several menopausal symptoms including hot flashes, sleep disturbance, irritability, muscle stiffness, and incontinence after controlling for covariates. These findings suggest that a potential mechanism in which bothersome menopausal symptoms may influence depressed mood during the midlife is through sleep disturbance. PMID:19128903

An examination of Anglo and Latino parenting practices: relation to behavior problems in children with or without developmental delay.

The transactional model of development has received empirical support in research on at-risk children. However, little is known about the role of ethnicity or child delay status (i.e., developmental delay [DD] or typical cognitive development [TD]) in the process of parents adapting to their child's behavior problems and special needs. We examined whether Latina (N=44) and Anglo (N=147) mothers of 3-year-old children with or without DD differed in their use of two parenting practices, maternal scaffolding and sensitivity. We also examined how the status and ethnic groups differed in child behavior problems at ages 3 and 5 and whether parenting predicted change in behavior problems over time in the ethnic and status groups. Analyses generally supported previous research on status group differences in behavior problems (DD higher) and parenting practices (TD higher). Parenting practices predicted a decrease in externalizing problems from child age 3 to 5 years among Latino families only. Child developmental status was not associated with change in behavior problems. Cultural perspectives on the transactional model of development and implications for intervention are discussed.

2011-03-01

With the current trend of globalization, unprecedented opportunities and enormous changes have emerged for the global development of traditional Chinese medicine (TCM). However, many old and new challenges and problems still remain, including partial or limited comprehension of acupuncture, oriental medicine and TCM, the existence of non-standardized institutes of TCM and acupuncture training schools, unqualified TCM practitioners, and problems concerning Chinese herbal medicine and inexperience in conducting TCM business. These problems will doubtlessly impede the further development of TCM worldwide in the foreseeable future. It is also clear that the globalization of TCM will require a large scale systematic project and constitute an arduous historical task. This paper aims to consolidate 6 strategic development modes to reinforce and facilitate the process of TCM globalization through a detailed analysis of both the present status and existing problems concerning the development of TCM in the United States.

To determine the oral status of elderly residents in nursing homes (NH) and long term care wards (LT) and to describe associations between oral status and nutritional status among institutionalized elderly residents. Descriptive, cross-sectional study. All elderly residents in all NH and LT in Helsinki, the capital of Finland. The study included 2036 out of 2424 (84 %) eligible subjects in NH, 1052 out of 1444 (73%) eligible subjects in LT, and all wards in NH (N = 92) and LT (N = 53). A structured questionnaire, oral examination, and Mini Nutritional Assessment (MNA) were completed by ward nurses for all participating residents. The structured questionnaire included information on oral status and oral health problems, demographic characteristics, functional status, diseases and medication. One questionnaire for each ward was used to evaluate the daily ward routines related to nutritional care and meal management. 11 % of the NH residents and 3 % of LH patients were well nourished. Of NH residents 60 % were at risk of malnutrition and 29 % were malnourished. The respective figures for LT patients were 40 % and 57 %. Nutritional status was significantly associated with oral status and with the number of oral health problems. Those with mixed dentition or complete dentures tended to have better nutritional status than those totally edentulous without prosthesis. Malnutrition increased consistently with the increasing number of oral health problems (including chewing problems, swallowing difficulties, pain in mouth and xerostomia). In the population of institutionalized frail elderly, malnutrition was related to both poor oral status and oral health problems.

Our objective was to explore the association between weight status and behavioral problems in children before school age. We examined whether the association between weight status and behavioral problems varied by age and sex. This study used cross-sectional data from a nationally-representative sample of children and their families in Chile (N = 11,207). These children were selected using a cluster-stratified random sampling strategy. Data collection for this study took place in 2012 when the children were 1.5-6 years of age. We used multivariable analyses to examine the association between weight status and behavioral problems (assessed using the Child Behavior Checklist), while controlling for child's sex, indigenous status, birth weight, and months breastfed; primary caregiver's BMI and education level; and household wealth. Approximately 24% of our sample was overweight or obese. Overweight or obese girls showed more behavioral problems than normal weight girls at age 6 (β = 0.270 SD, 95% CI = 0.047, 0.493, P = 0.018). Among boys age 1 to 5 years, overweight/obesity was associated with a small reduction in internalizing behaviors (β = -0.09 SD, 95% CI = -0.163, -0.006, P = 0.034). Our data suggest that the associations between weight status and behavioral problems vary across age and sex.

Background: High incidences of drug consumption and mental health problems are found among the Roma population in Spain, a reality that remains understudied. Past studies have indicated the positive role played by the Iglesia Evangélica Filadelfia (IEF) in promoting rehabilitation and prevention of these practices. Objective: In this article, authors analyze in which ways the IEF favors processes of drug rehabilitation and mental health recovery as well as the prevention of these problems among its Roma members. Methods: A communicative qualitative approach was developed. It was communicative because new knowledge was created by dialogically contrasting the existing state of the art with study participants. It was qualitative because everyday life stories were collected, gathering the experiences, perceptions and interpretations of Roma people who are actively involved in three different IEF churches based in Barcelona. Results: This article identifies these protective factors: anti-drug discourse, a supportive environment, new social relations, role model status, the promotion of interactions, the revaluation of oneself, spiritual activities and the improvement of the feeling of belonging and the creation of meaning. Conclusion: The present research contributes new evidence to the current understanding of the role played by the IEF in improving Roma health status and how the identified protective factors can contribute to rehabilitation and recovery from such problems in other contexts.

Artificial organs and regenerative medicine are the subjects of very active research and development (R&D) in Japan and various artificial organs are widely used in patients. Results of the R&D are presented at the annual conference of the Japanese Society for Artificial Organs (JSAO). Progress in the fields of artificial organs and regenerative medicine are reviewed annually in the Japanese Journal of Artificial Organs. The official English-language journal of JSAO, Journal of Artificial Organs, also publishes many original articles by Japanese researchers. Although the annual conference and the publications of JSAO provide the world with update information on artificial organs and regenerative medicine in Japan, the information is not always understood appropriately in the rest of the world, mainly due to language problems. This article therefore introduces the current status of artificial organs and regenerative medicine in Japan. Artificial hearts and metabolic support systems are reviewed here and other interesting areas such as regenerative medicine can be found elsewhere.

The authors’ expert assessment of the current state of the energy management system in the company is proposed in the article. The experts are invited to assess the status of the energy management system in the following categories: energy policy, organizational structure, training, motivation, control, communication, investment, and energy consumption culture. For the purposes of interpretation of the results of the expert evaluation obtained, a gradation based on a possible range of values is proposed. The expert evaluation allows representing the status of the energy management system in general and at each of its individual levels, which makes it possible to identify the problem areas more accurately. To confirm the applied nature of the proposed methodology, the authors assessed the opinions of 8 experts, employed by the road construction company of the Tyumen Region and related in one way or another to the process of energy consumption in the company due to the nature of their activities.

2018-03-15

Currently, two food sufficiency questions are utilised as a proxy measure of national food security status in Australia. These questions do not capture all dimensions of food security and have been attributed to underreporting of the problem. The purpose of this study was to investigate food security using the short form of the US Household Food Security Survey Module (HFSSM) within an Australian context; and explore the relationship between food security status and multiple socio-demographic variables. Two online surveys were completed by 2334 Australian participants from November 2014 to February 2015. Surveys contained the short form of the HFSSM and twelve socio-demographic questions. Cross-tabulations chi-square tests and a multinomial logistic regression model were employed to analyse the survey data. Food security status of the respondents was classified accordingly: High or Marginal (64%, n = 1495), Low (20%, n = 460) or Very Low (16%, n = 379). Significant independent predictors of food security were age (P < .001), marital status (P = .005), household income (P < .001) and education (P < .001). Findings suggest food insecurity is an important issue across Australia and that certain groups, regardless of income, are particularly vulnerable. Government policy and health promotion interventions that specifically target "at risk" groups may assist to more effectively address the problem. Additionally, the use of a multi-item measure is worth considering as a national indicator of food security in Australia. © 2018 Australian Health Promotion Association.

Participants were grouped based on drinking status: (1) current drinkers (CDs; n=132) or (2) nondrinkers (NDs; n=60). Questionnaires assessed frequency of alcohol use, motives for drinking, problem identification, as well as anxiety and depression (i.e., Hamilton scales). Bivariate analyses showed that CDs were more likely than NDs to be single, have a HRO, and have greater anxiety and depression; for example, 91.7% of CDs had a HRO as compared to 56.7 % of NDs. Drinking status was not significantly related to age or gender. Among CDs, common motives for use included: to reduce anxiety and fears (60.6%), because my friends use alcohol (75.0%), to fight stress (78.8%), and to increase self-esteem (64.4%). Among CDs, past month drinking days were: 25% 1–2 days, 37.9% 3–7 days, 25% 8–21 days, and 12.1% 22–30 days. Regarding problem identification, 29.5% reported not having a problem, 34.8% reported possibly having a problem, 21.9% reported having a problem but not needing help, and 13.6% reported having a problem/needing help. Young adults involved in HRO may be a particularly high risk population given increased likelihood of alcohol use, anxiety, and depression. Early intervention strategies that incorporate motivational interviewing approaches to address coping and social motives for use may be beneficial to address substance use and mental health problems.

This study examined alcohol consumption in relation to anxiety, depression, and involvement with high risk occupations (HRO; e.g., coal miners), among young adults in the Ukraine (aged 18-25) (N = 192; 60.9% male; 100% Caucasian). Participants were grouped on the basis of drinking status: (1) current drinkers (CDs; n = 132) or (2) nondrinkers (NDs; n = 60). Questionnaires assessed frequency of alcohol use, motives for drinking, problem identification, as well as anxiety and depression (i.e., Hamilton scales).

Gloss, Blair B.

1992-01-01

The construction of the National Transonic Facility was completed in September 1982 and the start-up and checkout of the tunnel systems were performed over the following two years. In August 1984, the facility was declared operational for final checkout of cryogenic instrumentation and control systems, and for the aerodynamics calibration and testing to commence. Since 1984 several operational problems have been identified and successfully solved which is demonstrated by the fact that the facility has operated the last year with no significant facility down times. Also during this time period, development of test techniques and instrumentation has continued. This paper will review some of the recent test techniques and instrumentation developments, and will briefly review the status of the facility.

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

Recruitment problems in surgical disciplines have become an increasingly debated topic. On the one hand current career prospects appear to be less attractive than those were seen for the previous generation. On the other hand the demands for a so-called "work-life balance" have changed and the proportion of female students and colleagues in medicine has risen and will continue to increase. Although Plastic Surgery currently seems to be less affected by these problems than other surgical disciplines, securing a qualified supply of young academics in Plastic Surgery is a prerequisite for the further development of this discipline. The traditional model of mentoring is discussed and the role of coaching in a sense of helping the mentorees examine what they are doing in the light of their intentions and goals is reflected. The present article tries to analyze the current status of academic Plastic Surgery from the viewpoint of German university senior surgeons in academic plastic surgery, and aims to highlight the specific prospects for young academics against the backdrop of an often one-sided and superficial perception of this profession. © Georg Thieme Verlag KG Stuttgart · New York.

Small satellites need launching services using small launchers capable of injecting 100 to 1000 kg into a polar orbit at an altitude of 1000 km. Operational small launchers are reviewed as well as developing and planned ones. Launcher characteristics, constraints, performance, and status are detailed. Few technical problems are encountered, as most launcher projects call for existing components and well known technologies. Most of the difficulties have come from launch site availability and from financial considerations.

Youth with chronic physical health problems often experience social and emotional problems. We investigate the relationship between participation in the Big Brothers Big Sisters of Canada community-based mentoring programs (BBBS) and youth social and mood outcomes by youth health status. Youth newly enrolled in BBBS were classified by health status (one or more chronic physical health problems without activity limitation, n = 191; one or more chronic physical health problems with activity limitation, n = 94; no chronic health problem or activity limitation, n = 536) and mentoring status (yes/no) at 18 month follow-up. Youth outcomes measured at follow-up were social anxiety, depressed mood, and peer self-esteem. Youth with chronic health problems and activity limitation were more likely to live with two biological parents, use mental health or social services, and have parents who reported difficulties with depressed mood, social anxiety, family functioning and neighbourhood problems. At 18 month follow-up, mentored youth in this health status group experienced fewer symptoms of social anxiety and higher peer self-esteem compared to non-mentored youth. Mentored youth with chronic health problems without activity limitation and mentored youth with no health problems or limitations did not show significant improvements in social anxiety and peer self-esteem. Regardless of their health status, mentored youth reported fewer symptoms of depressed mood than non-mentored youth. Youth with chronic health problems, particularly those with activity limitation as well, demonstrate a capacity to experience social and mood benefits associated with mentoring.

2008-01-01

In the last two decades, the curriculum in medical education has changed so as to maintain its efficiency and effectiveness. Considerable changes are underway in many medical colleges worldwide. This study assessed the current status of the undergraduate curricula in the medical colleges of the Gulf Cooperative Council (GCC) countries, in relation to the SPICES (student-centered, problem-based, integrated, community-based, elective and systematic) model. A structured open-ended data form was used in the collection of information from the appropriate authorities in 30 medical colleges of the GCC countries (Saudi Arabia, Oman, Kuwait, Qatar, Bahrain, United Arab Emirates and Yemen) in the year 2005. Of 30 medical colleges, 13 (43.3%) were located in Saudi Arabia. The annual intake of students in the year 2005 in these 30 colleges was 3225, of which 64.15% were males. Twelve colleges (40%) followed the traditional curriculum, while the remaining (60%) followed a hybrid problem-based learning (PBL) curricula. Most of the colleges were moving towards the more desirable aspects of the SPICES model. The majority of the traditional colleges were planning to change their curricula to hybrid PBL curricula. Almost all new medical colleges were adopting the hybrid PBL curricula. Despite the diversity in the curricula followed in medical colleges in GCC countries, most of these colleges either are following or are moving towards the new trends in medical education curricula.

Life-Time Risk for Substance Use Among Offspring of Abusive Family Environment From the Community

2018-01-01

The current study examined the cumulative risk, age of initiation, and functional impairments among adults with substance use problems (N = 1748) by child abuse status. Child abuse was associated with earlier initiation of marijuana, cocaine, and heroin use, and had greater risks for all the drugs studied (hazard ratios, 1.7–3.2). Furthermore, child abuse was associated with increased medical and functional impairments, including ER visits, health problems, drug dealing, drug dependence, and drug cravings. Provision of social services and parenting education during the perinatal period may prevent the long-term impact of child abuse on substance use and related impairments. The study’s limitations are noted. PMID:22780838

Beyond singular values and loop shapes

NASA Technical Reports Server (NTRS)

Stein, G.

1985-01-01

The status of singular value loop-shaping as a design paradigm for multivariable feedback systems is reviewed. It shows that this paradigm is an effective design tool whenever the problem specifications are spacially round. The tool can be arbitrarily conservative, however, when they are not. This happens because singular value conditions for robust performance are not tight (necessary and sufficient) and can severely overstate actual requirements. An alternate paradign is discussed which overcomes these limitations. The alternative includes a more general problem formulation, a new matrix function mu, and tight conditions for both robust stability and robust performance. The state of the art currently permits analysis of feedback systems within this new paradigm. Synthesis remains a subject of research.

Software risk management through independent verification and validation

Software project managers need tools to estimate and track project goals in a continuous fashion before, during, and after development of a system. In addition, they need an ability to compare the current project status with past project profiles to validate management intuition, identify problems, and then direct appropriate resources to the sources of problems. This paper describes a measurement-based approach to calculating the risk inherent in meeting project goals that leverages past project metrics and existing estimation and tracking models. We introduce the IV&V Goal/Questions/Metrics model, explain its use in the software development life cycle, and describe our attempts to validate the model through the reverse engineering of existing projects.

Current Status of Regulatory Science Education in Faculties of Pharmaceutical Science in Japan.

PubMed

Tohkin, Masahiro

2017-01-01

I introduce the current pharmaceutical education system in Japan, focusing on regulatory science. University schools or faculties of pharmaceutical science in Japan offer two courses: a six-year course for pharmacists and a four-year course for scientists and technicians. Students in the six-year pharmaceutical course receive training in hospitals and pharmacies during their fifth year, and those in the four-year life science course start research activities during their third year. The current model core curriculum for pharmaceutical education requires them to "explain the necessity and significance of regulatory science" as a specific behavior object. This means that pharmacists should understand the significance of "regulatory science", which will lead to the proper use of pharmaceuticals in clinical practice. Most regulatory science laboratories are in the university schools or faculties of pharmaceutical sciences; however, there are too few to conduct regulatory science education. There are many problems in regulatory science education, and I hope that those problems will be resolved not only by university-based regulatory science researchers but also by those from the pharmaceutical industry and regulatory authorities.

Stress and type 2 diabetes: a review of how stress contributes to the development of type 2 diabetes.

PubMed

Kelly, Shona J; Ismail, Mubarak

2015-03-18

Current policy and research around type 2 diabetes (T2D) interventions largely invoke a behavioral model. We suggest that activation of the physiologic stress response (PSR) from chronic exposure to stressors, low socioeconomic status (SES), severe mental health problems, or aggressive behavior increases the risk of T2D. This article is a comprehensive review of the literature on the link between T2D and psychosocial factors focusing on prospective studies of the risk for developing diabetes. The review found an increased risk for T2D in people: exposed to stressful working conditions or traumatic events; with depression; with personality traits or mental health problems that put them in conflict with others; of low SES, either currently or in childhood; and in racial/ethnic minority populations, independent of current SES. This review suggests that T2D prevention research would be more effective if (a) the PSR to psychosocial factors (especially social disparities) was recognized and (b) intervention programs evaluated reduction in social disparities as part of a comprehensive approach.

Oral health matters for the nutritional status of older persons-A population-based study.

To explore the association between oral health and nutritional status in the context of daily care for older people. Oral problems often increase with age and affect a person's ability to chew and swallow. They might also influence the ability to maintain a satisfactory nutritional status. Oral health awareness is therefore of great importance in nursing care for older people. A retrospective cross-sectional study. Data from the Swedish quality register, Senior Alert, were used, including structured assessments of both oral and nutritional status using the Revised Oral Assessment Guide-Jönköping and the Mini Nutritional Assessment. In total, 1,156 persons (mean age: 82.8 ± 7.9) had both oral and nutritional assessments registered by the nursing staff in daily care. Approximately 29% of participants had moderate oral health problems. Another 12% had severe problems. Over 60% of the persons were considered at risk of malnutrition or were malnourished. There was a weak correlation between poor nutritional status and poor oral health, and approximately one-third of the persons who were at risk or malnourished had simultaneous oral problems. A multivariate logistic regression revealed that when problems involving voice and swallowing were present, there was also a greater possibility of being assessed as at risk of malnourishment or being malnourished. There is a relationship between oral health problems and nutritional status, indicating the importance of evaluating oral health status in older persons with nutritional problems. Nursing staff involved in care for older people should be aware of the importance of including regular oral health check-ups in their work. There is also a need for nursing staff members and oral health professionals to exchange knowledge. © 2017 John Wiley & Sons Ltd.

[Integral obstetrics impeded by history? Midwives and gynaecologists through the ages].

2016-01-01

There is a long and complicated history concerning the interprofessional collaboration between midwives and gynaecologists, which is still evident in current practice. Yet, in the analysis of collaborative problems, history and its lessons are often overlooked. Consequently, less effective solutions to problems may be found, because the root cause of a problem is not addressed. In this historical perspective we show how policies of the respective professions have often focused on self-preservation and competition, rather than on effective collaboration. We also highlight how the independent midwives lost and regained authorisation, status and income. Finally, using a theoretical model for interprofessional collaboration, we reflect on where history impedes the development of integral obstetrics. The focus must be averted away from professional self-interest and power struggles, but this proves to be a complex exercise.

Interparental aggression, attention skills, and early childhood behavior problems

2014-01-01

The current study explored longitudinal associations between interparental aggression, the development of child attention skills, and early childhood behavior problems in a diverse sample of 636 families living in predominately low-income, nonmetropolitan communities. The results of latent-variable, cross-lagged longitudinal models revealed that maternal-reported interparental aggression in infancy predicted reduced observed attention skills in toddlerhood; no association was observed, however, between attention in infancy and interparental aggression during the toddler years. Further, reduced toddler attention and high interparental aggression were both associated with increased risk for attention-deficit/hyperactivity disorder symptoms and conduct problems at 3 years of age. Processes largely operated in similar ways regardless of child gender or low-income status, although a few differences were observed. Overall, the results suggest that interparental aggression undermines attention development, putting children’s early behavioral adjustment at risk. PMID:23786696

Rethinking the relationship between socioeconomic status and health: Challenging how socioeconomic status is currently used in health inequality research.

PubMed

Gagné, Thierry; Ghenadenik, Adrian E

2018-02-01

The Scandinavian Journal of Public Health recently reiterated the importance of addressing social justice and health inequalities in its new editorial policy announcement. One of the related challenges highlighted in that issue was the limited use of sociological theories able to inform the complexity linking the resources and mechanisms captured by the concept of socioeconomic status. This debate article argues that part of the problem lies in the often unchallenged reliance on a generic conceptualization and operationalization of socioeconomic status. These practices hinder researchers' capacity to examine in finer detail how resources and circumstances promote the unequal distribution of health through distinct yet intertwined pathways. As a potential way forward, this commentary explores how research practices can be challenged through concrete publication policies and guidelines. To this end, we propose a set of recommendations as a tool to strengthen the study of socioeconomic status and, ultimately, the quality of health inequality research. Authors, reviewers, and editors can become champions of change toward the implementation of sociological theory by holding higher standards regarding the conceptualization, operationalization, analysis, and interpretation of results in health inequality research.

The present study examined predictors of emotional problems amongst a nationally representative cohort of recent immigrants in Canada. Specifically, the effects of parenting status were examined given the association between parenting stress and mental health. Data came from the Longitudinal Survey of Immigrants to Canada (N = 7055). Participants were recruited 6-months post landing (2001–2002) and followed up at 2 and 4 years. Self-reported emotional problems over time were considered as a function of parenting status (Two Parent, Lone Parent, Divorced Non-Parent, Non-Divorced Non-Parent) and sociodemographic characteristics. Odds of emotional problems were higher among Two Parent, OR = 1.12 (1.01, 1.24), Lone Parent, OR = 2.24 (1.75, 2.88), and Divorced Non-Parent, OR = 1.30 (1.01, 1.66) immigrants compared to Non-Divorced Non-Parents. Visible minority status, female gender, low income, and refugee status were associated with elevated risk. Findings reveal that immigrant parents are at risk for emotional health problems during the post-migration period. Such challenges may be compounded by other sociodemographic risk. PMID:28376118

Non-human primates (NHPs) are phylogenetically close to humans, with many similarities in terms of physiology, anatomy, immunology, as well as neurology, all of which make them excellent experimental models for biomedical research. Compared with developed countries in America and Europe, China has relatively rich primate resources and has continually aimed to develop NHPs resources. Currently, China is a leading producer and a major supplier of NHPs on the international market. However, there are some deficiencies in feeding and management that have hampered China's growth in NHP research and materials. Nonetheless, China has recently established a number of primate animal models for human diseases and achieved marked scientific progress on infectious diseases, cardiovascular diseases, endocrine diseases, reproductive diseases, neurological diseases, and ophthalmic diseases, etc. Advances in these fields via NHP models will undoubtedly further promote the development of China's life sciences and pharmaceutical industry, and enhance China's position as a leader in NHP research. This review covers the current status of NHPs in China and other areas, highlighting the latest developments in disease models using NHPs, as well as outlining basic problems and proposing effective countermeasures to better utilize NHP resources and further foster NHP research in China.

Current Status and Research into Overcoming Limitations of Capsule Endoscopy

Kwack, Won Gun; Lim, Yun Jeong

2016-01-01

Endoscopic investigation has a critical role in the diagnosis and treatment of gastrointestinal (GI) diseases. Since 2001, capsule endoscopy (CE) has been available for small-bowel exploration and is under continuous development. During the past decade, CE has achieved impressive improvements in areas such as miniaturization, resolution, and battery life. As a result, CE is currently a first-line tool for the investigation of the small bowel in obscure gastrointestinal bleeding and is a useful alternative to wired enteroscopy. Nevertheless, CE still has several limitations, such as incomplete examination and limited diagnostic and therapeutic capabilities. To resolve these problems, many groups have suggested several models (e.g., controlled CO2 insufflation system, magnetic navigation system, mobile robotic platform, tagging and biopsy equipment, and targeted drug-delivery system), which are in development. In the near future, new technological advances will improve the capabilities of CE and broaden its spectrum of applications not only for the small bowel but also for the colon, stomach, and esophagus. The purpose of this review is to introduce the current status of CE and to review the ongoing development of solutions to address its limitations. PMID:26855917

“Man-ing” up and Getting Drunk: The Role of Masculine Norms, Alcohol Intoxication and Alcohol-Related Problems among College Men

2011-01-01

Compared to college women, college men face elevated risks for problematic drinking and negative alcohol-related consequences. These risks highlight the critical need to investigate gender issues and risk factors contributing to intoxication and related problems among men. Theoretical models suggest that conforming to masculine norms or the beliefs and expectations of what it means to be a man, may help explain patterns of problematic drinking among men. The current study advances the literature by investigating the association between masculine norms, drinking to intoxication, and alcohol-related consequences among 776 undergraduate males after taking into account the importance of fraternity status and perceived peer norms. Results indicate that fraternity status and higher perceived peer norms regarding drinking increased the risks of getting drunk and experiencing alcohol-related consequences. Specifically, the masculine norms of being a “playboy”, risk-taking, and winning were risk factors of drinking to intoxication; while, being a “playboy”, risk-taking, and self-reliance increased the risks of alcohol-related problems. Primacy of work and heterosexual presentation were two masculine norms that were protective of drinking to intoxication. Our findings contribute to important future considerations for prevention, clinical interventions, and public-health implications in college settings. PMID:21620570

Many stroke patients may have oral problems and systemic diseases, but clinical information on treatment provided to stroke patients for dental problems during inpatient rehabilitation is rare. The objective of this study was to research stroke inpatients' requirements for dental treatment and the accompanying risks. We included 165 stroke patients undergoing inpatient rehabilitation at Morinomiya Hospital during the year 2010 and researched the causes of stroke and the patients' orodental status, underlying diseases, antithrombotic drugs prescribed and special considerations or difficulties in the treatment. Cerebral infarction was the most common causes of stroke. Many patients had hypertension, heart disease or diabetes mellitus, and 54.5% had been prescribed antithrombotic drugs. Dentists diagnosed 57.0% patients with untreated dental cavities. Approximately 30% did not use dentures despite having a requirement. In total, 142 patients underwent dental treatment including periodontal treatment, prosthetic treatment and tooth extraction under management of circulation and haemostasis such as monitoring vital signs and surgical splints in cases of the difficult extraction. The current study revealed a high requirement for dental treatment among stroke patients and demonstrated the effectiveness of performing dental treatment during inpatient rehabilitation of these patients. © 2014 John Wiley & Sons A/S and The Gerodontology Society.

2013-08-01

The linkage between sleep quality and weight status among teenagers has gained more attention in the recent literature and health policy but no consensus has been reached. Using both a propensity score method and multivariate linear regression for a cross-sectional sample of 2,113 teenagers, we analyzed their body mass index (BMI) in relation to sleep quality while controlling for family characteristics (household income, parent/guardian level of education, disability status, work night shift, and smoking) and individual factors (age, sex, regular exercise, smoking, employment, and feeling secure in the neighborhood). Sleep quality was assessed using 3 scales: difficulty in initiating sleep, difficulty in maintaining sleep, and non-restorative sleep, based on Diagnostic and Statistical Manual of Mental Disorders-IV-defined insomnia. Considering all 3 types of poor sleep quality, 20.9% of teenagers in Taiwan experienced some form of sleep problems. After adjusting for the other variables, 2 factors independently and statistically predicted sleep problems: current smoking and working night shifts by the head of the household. Teens experiencing difficulty in initiating sleep had higher BMIs ranging from 0.86 to 1.41 units. Efforts to address childhood obesity need to take into consideration sleep problems that are highly prevalent among teenagers. © 2013, American School Health Association.

Purpose To examine separate mediational models linking a) menarcheal status or b) pubertal timing to internalizing and externalizing problems through competence. Method Cross-sectional analyses of 262 adolescent girls (11–17 years; M=14.93, SD=2.17) enrolled in a longitudinal study examining the association of psychological functioning and smoking with reproductive and bone health. Measures of menarcheal status (pre/post), pubertal timing (early, on-time, or late), internalizing and externalizing behavior, and perceived competence (parent and adolescent report) were obtained. Structural Equation Modeling was used for analyses. Results Perceived competence was found to fully mediate the association between menarcheal status and parent report of internalizing and externalizing problems. For adolescent report, there was a full mediation effect for internalizing problems but a partial mediation effect for externalizing problems. Being menarcheal was related to lower competence which was related to higher internalizing and externalizing problems. Models including pubertal timing were not significant. Conclusions Perceived competence is important in understanding the associations between menarcheal status and internalizing and externalizing problems. Interventions targeting competence, particularly in post-menarcheal girls, may reduce or prevent problem behaviors. PMID:21939864

2015-07-01

The objective of this study was to identify the current status of stream water-quality assessment and reporting methods for four states in the Ohio River basin (Indiana, Ohio, Tennessee, and Virginia), as required by the 305(b) section of the United States (US) Clean Water Act. Specifically, we clarified the discrepancies that exist among stream-impairment status classified by benthic macroinvertebrate multimetric indices (MMIs) and depicted using Geographic Information Systems shapefiles. In addition, we provided guidance in solving some of the comparability problems that arise when developing state-specific MMIs and depicting stream-impairment status using Geographic Information Systems technology. The MMI variation among states and differences in shapefile formats resulted in a nationwide dataset, which cannot be directly compared. Incorporating the changes suggested in this study allow for a uniform assessment and reporting method nationwide. Successful implementation of these changes would strengthen the US Environmental Protection Agency efforts to identify impaired streams and sources of those impairments without the limitations of state-by-state .developed assessment methods.

The current study examines the prevalence and correlates of homebound status aiming to elucidate the predictors and implications of being homebound. Analyzed sample was drawn from two representative cohorts of older persons in Israel, including 1191 participants (mean age = 83.10 ± 5.3 years) of the first wave of the Cross-Sectional and Longitudinal Aging Study (CALAS) and 418 participants (mean age = 83.13 ± 5.2) of the Israeli Multidisciplinary Aging Study (IMAS). Cross-sectional and longitudinal analyses were conducted. Homebound prevalence rates of 17.7% -19.5% were found. Homebound participants tended to be older, female, have obese or underweight body mass index (BMI), poorer health, lower functional status, less income, higher depressed affect, were significantly lonelier (in CALAS), and more likely to have stairs and no elevators, than their counterparts. Predictors of becoming homebound include low functional IADL status, having stairs and no elevator (in both cohorts), old age, female gender, and being obese or underweight (in CALAS). The study shows homebound status is a prevalent problem in old-old Israelis. Economic and socio-demographic resources, environment, and function play a role in determining the older person's homebound status. Implications for preventing homebound status and mitigating its impact with regards to the Israeli context are discussed. PMID:21420181

To explore factors associated with long-term outcomes of work and marital status in individuals who had experienced a mild head injury (MHI), as well as those who had not. Population-based study using logistical regression analyses to investigate the impact of preinjury characteristics on work and marital status. Two groups of Vietnam-era Army veterans: 626 who had experienced a MHI an average of 8 years before examination, and 3,896 who had not. Demographic characteristics, concurrent medical conditions, early life psychiatric problems, loss of consciousness (LOC), and interactions among these variables were used to predict current work and marital status. Multiple variables were associated with work and marital status in the sample with MHI, accounting for approximately 23% and 17% of the variance in these two outcome variables, respectively. In contrast, the same factors accounted for significantly less variance in outcome in the sample without a head injury-13.3% and 9.4% for work and marital status, respectively. These findings suggest a more potent role for and increased vulnerability to the influence of demographic, medical, and psychiatric factors on outcomes after a MHI. That is, MHI itself moderates the influence of preinjury characteristics on work and marital status. In addition, in those who had a MHI, moderator relationships were found between education and LOC for both work and marital status. Similarly, complex moderator relationships among race, region of residence, and LOC were found for both work and marital status outcomes.

This study was undertaken to investigate the clinical features of oral motor dysfunction and feeding problems as well as the nutritional status of children with cerebral palsy (CP). Fifty-nine CP children, 39 boys and 20 girls, mean age 31 months (20 to 72 months), were recruited. Their parents were interviewed for high risk factors and feeding history. Each case was assessed for oral motor and feeding problems based on oral motor and feeding skill score; for nutritional status by measurement of weight, height; neurologically for type of cerebral palsy and for developmental age by Gesell's developmental scale. Equal number of age and sex matched controls were included for comparison of nutritional status, oral motor and feeding skill score. Among 59 patients, 51 cases had oral motor dysfunction and 55 cases had feeding problems including all athtosis, spastic tetraplegia, and 16 had spastic diplegia. The scores of both the mean oral motor function and feeding skill of CP children were significantly lower than those of the controls (P < 0.001). Main food of children with cerebral palsy consisted of liquid and semisolid diet. Body weight and height below the 25th percentile were found in 13 cases and 19 cases, respectively. The majority of the children with cerebral palsy had oral motor dysfunction and feeding problems which appeared in early age and disturbed the growth and nutritional status. Thorough assessment for oral motor function, feeding problems and nutritional status of CP children is indicated in order to start timely rehabilitation and nutritional interventions which can significantly improve their nutritional status and quality of life.

The void in using urine concentration to assess population fluid intake adequacy or hydration status.

2016-09-01

Urine concentration can be used to assess fluid intake adequacy or to diagnose dehydration. However, too often urine concentration is used inappropriately to draw dubious conclusions that could have harmful health and economic consequences. Inappropriate uses of urine concentration relate primarily to convenience sampling (timing) and problems related to convenience sampling (misapplication of thresholds), but a conceptual problem also exists with using urine concentration in isolation. The purpose of this Perspective article is to briefly explain the problematic nature of current practices and to offer a possible solution to improve practice with minimal added complication. When urine is used exclusively to assess fluid intake adequacy and hydration status in adults, we propose that only when urine concentration is high (>850 mmol/kg) and urine excretion rate is low (<850 mL/24 h) should suspicion of inadequate drinking or impending dehydration be considered. Prospective tests of the 850 × 850 thresholds will provide supporting evidence and/or help refine the best thresholds for men and women, young and old. © 2016 American Society for Nutrition.

A cross sectional study was carried out among medical students in the University of Ibadan to identify their socio economic and psychological problems. Three hundred and sixteen students, 159 males and 157 females participated in the study. The questionnaire, which was self-administered, sought information about sources of financial support, type of accommodation, use of recreational facilities, smoking and drinking habits and sources of stress and insecurity on the campus. The GHQ-12 was used to assess their mental status. Ninety-four percent of students were sponsored by their parents. Average monthly income as pocket money ranged from N800-N15,000. Sixty-three (20%) reported that their pocket money was inadequate and 11 (3.5%) engage in business ventures to supplement their income. Two hundred and fifty-seven (81%) live on the campus, 11 (3.5%) were current smokers and 54 (18%) were current drinkers. Stealing and lack of money were the commonest causes of insecurity on the campus. Lack of money, fear of failure of examinations, family problems and broken relationships were reported as causes of depression among this study population. GHQ scores ranged from 1 to 9 using a cut-off point of 3 scores, 38 students (12.0%) were categorised as having traits of poor mental health. GHQ scores were not associated with age, sex, smoking or drinking status or students' assessment of the adequacy of their pocket money. However, living off campus and poor self-perception were associated with poor mental health (p < 0.01). Counseling services should be provided in the medical school to assist students to handle issues that constitute a source of stress in their psychosocial environment.

2016-09-25

The prevalence of gastroesophageal reflux disease (GERD) and the incidence of some of its complications have risen strikingly over the last few decades. With the increase in our understanding of the pathophysiology of GERD along with the development of proton pump inhibitors, the diagnostic and therapeutic approaches to GERD have changed dramatically over the past decade. However, GERD still poses a problem to many clinicians since the spectrum of the disease has evolved to encompass more challenging presentations such as refractory GERD and extra-esophageal manifestations. The aim of this article is to provide a review of available current translational research on GERD. This review includes acid pocket, ambulatory pH monitoring, impedance pH monitoring, mucosa impedance, and high resolution manometry. This article discusses current translational research on GERD.

Oscillation studies play a central role in elucidating at least some aspects of the flavor problem. Here we examine the status of the predictions of a lepton quarticity flavor theory of neutrino oscillations against the existing global sample of oscillation data. By performing quantitative simulations we also determine the potential of the upcoming DUNE experiment in narrowing down the currently ill-measured oscillation parameters θ23 and δCP. We present the expected improved sensitivity on these parameters for different assumptions.

Gauge theories with compact symmetry groups possess topologically nontrivial configurations of gauge field. This characteristic has dramatic implications for the vacuum structure of quantum chromodynamics (QCD) and for the behavior of QCD plasma, as well as for condensed matter systems with chiral quasi-particles. Here, I review the current status of this problem with an emphasis both on the interplay between chirality and a background magnetic field and on the observable manifestations of topology in heavy-ion collisions, Dirac semimetals, neutron stars, and the early Universe.

Adolescent tobacco use is a major public health problem. However, there is little information about the impact of tobacco advertising and availability near schools on adolescent tobacco use in India. The various tobacco products and brands available in outlets within 100 meters of two high schools in an Indian town were identified. A stratified random sample of 172 participants from these two schools completed a questionnaire on tobacco use and socioeconomic status. Eighteen outlets selling tobacco products were identified. In the two schools the current use of smoked and smokeless tobacco was 9.1% and 17.4% respectively. School location and low socio-economic status of adolescents were associated with tobacco awareness of advertisements (p=0.001) and the receipt of a free sample (p= 0.032). Advertisements on billboards, posters and the receipt of a free tobacco sample were significant factors (p=0.031, p=0.016, p=0.017 respectively) in current tobacco use. In this study a significant proportion of adolescents used tobacco. Tobacco- promotion activities (advertising, the receipt of a free sample), school location and economic status were found to be associated with adolescent tobacco initiation. The local environment should be included in the prevention of adolescent tobacco initiation.

A disputed social status among peers puts children and adolescents at risk for developing a wide range of problems, such as being bullied. However, there is a lack of knowledge about which early predictors could be used to identify (young) adolescents at risk for a disputed social status. The aim of this study was to assess whether preventive child health care (PCH) findings on early childhood predict neglected and rejected status in early adolescence in a large longitudinal community-based sample. Data came from 898 participants who participated in TRAILS, a longitudinal study. Information on early childhood factors was extracted from the charts of routine PCH visits registered between infancy and age of 4 years. To assess social status, peer nominations were used at age of 10-12 years. Multinomial logistic regression showed that children who had a low birth weight, motor problems, and sleep problems; children of parents with a low educational level (odds ratios [ORs] between 1.71 and 2.90); and those with fewer attention hyperactivity problems (ORs = .43) were more likely to have a neglected status in early adolescence. Boys, children of parents with a low educational level, and children with early externalizing problems were more likely to have a rejected status in early adolescence (ORs between 1.69 and 2.56). PCH findings on early childhood-on motor and social development-are predictive of a neglected and a rejected status in early adolescence. PCH is a good setting to monitor risk factors that predict the social status of young adolescents. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

The aim of this study was to examine the relationship between family environment (cohesion and parental bonding), high-risk status, and psychopathology (internalizing and externalizing problems) among offspring of parents with bipolar disorder (BD), from the perspective of both offspring and their parents. We further tested if family environment mediated the relationship between bipolar risk status and internalizing and externalizing problems. High-risk (n = 90) BD offspring and control (n = 56) offspring aged 12-21 years old, and their parents, completed questionnaires on family cohesion and offspring internalizing and externalizing problems. Offspring also completed a parental bonding questionnaire. Group differences were examined, followed by multi-level mediation analysis with maximum likelihood and robust standard errors. Both offspring and parents in the high-risk group reported higher levels of internalizing and externalizing problems than controls. According to offspring reports, high-risk status, lower maternal and paternal care in parental bonding, was independently associated with internalizing problems. Lower maternal care alone predicted externalizing problems. Family environment did not mediate the relationship between bipolar risk status, and offspring problems. Due to rates of missing data from parent reports of offspring psychopathology, mediation analysis was completed using offspring reports. The offspring-report data presented indicate that low parental warmth and connection were associated with internalizing and externalizing problems as an independent risk factor, in addition to bipolar risk status. The parent-child relationship therefore warrants attention as a potential target for prevention strategies with such families. Copyright © 2017 Elsevier B.V. All rights reserved.

Finnmark Heart Study: employment status and parenthood as predictors of psychological health in women, 20-49 years.

1994-02-01

This study examined the influence of employment status and presence of young children in the household on psychological health in a population-based sample of 3103 women aged 20-49 years. Women were classified by employment status and parental status, thus creating four groups for comparison. After excluding women reporting chronic diseases and women receiving sickness, rehabilitation, unemployment or disability benefits, analyses indicated that problems of coping, dissatisfaction with life, depression and loneliness were greatest among homemakers, particularly among those with young children. Analyses adjusted for age, education, marital status and place of residence yielded similar results. Stratification by marital status and place of residence revealed two exceptions to this general pattern: unmarried employed women with young children had the highest rate of coping problems--and parenthood, not employment status, was the most important factor for psychological health problems in rural areas. Discrepancies between an individual's behaviour and the norm in society regarding women's employment, may partly explain the findings.

Management of community-acquired pneumonia in older adults

2014-01-01

Community-acquired pneumonia (CAP) is an increasing problem among the elderly. Multiple factors related to ageing, such as comorbidities, nutritional status and swallowing dysfunction have been implicated in the increased incidence of CAP in the older population. Moreover, mortality in patients with CAP rises dramatically with increasing age. Streptococcus pneumoniae is still the most common pathogen among the elderly, although CAP may also be caused by drug-resistant microorganisms and aspiration pneumonia. Furthermore, in the elderly CAP has a different clinical presentation, often lacking the typical acute symptoms observed in younger adults, due to the lower local and systemic inflammatory response. Several independent prognostic factors for mortality in the elderly have been identified, including factors related to pneumonia severity, inadequate response to infection, and low functional status. CAP scores and biomarkers have lower prognostic value in the elderly, and so there is a need to find new scales or to set new cut-off points for current scores in this population. Adherence to the current guidelines for CAP has a significant beneficial impact on clinical outcomes in elderly patients. Particular attention should also be paid to nutritional status, fluid administration, functional status, and comorbidity stabilizing therapy in this group of frail patients. This article presents an up-to-date review of the main aspects of CAP in elderly patients, including epidemiology, causative organisms, clinical features, and prognosis, and assesses key points for best practices for the management of the disease.

Threshold values and management options for nutrients in a catchment of a temperate estuary with poor ecological status

Intensive farming has severe impacts on the chemical status of groundwater and streams and consequently on the ecological status of dependent ecosystems. Eutrophication is a widespread problem in lakes and marine waters. Common problems are hypoxia, algal blooms, fish kills, and loss of water clarity, underwater vegetation, biodiversity and recreational value. In this paper we evaluate the nitrogen (N) and phosphorus (P) concentrations of groundwater and surface water in a coastal catchment, the loadings and sources of N and P, and their effect on the ecological status of an estuary. We calculate the necessary reductions in N and P loadings to the estuary for obtaining a good ecological status, which we define based on the number of days with N and P limitation, and the corresponding stream and groundwater threshold values assuming two different management options. The calculations are performed by the combined use of empirical models and a physically based 3-D integrated hydrological model of the whole catchment. The assessment of the ecological status indicates that the N and P loads to the investigated estuary should be reduced to levels corresponding to 52 and 56% of the current loads, respectively, to restore good ecological status. Model estimates show that threshold total N (TN) concentrations should be in the range of 2.9 to 3.1 mg l-1 in inlet freshwater (streams) to Horsens estuary and 6.0 to 9.3 mg l-1 in shallow aerobic groundwater (∼ 27-41 mg l-1 of nitrate), depending on the management measures implemented in the catchment. The situation for total P (TP) is more complex, but data indicate that groundwater threshold values are not needed. The stream threshold value for TP to Horsens estuary for the selected management options is 0.084 mg l-1. Regional climate models project increasing winter precipitation and runoff in the investigated region resulting in increasing runoff and nutrient loads to the Horsens estuary and many other coastal waters if present land use and farming practices continue. Hence, lower threshold values are required in many coastal catchments in the future to ensure good status of water bodies and ecosystems.

Animal models for dengue vaccine development and testing

Dengue fever is a tropical endemic disease; however, because of climate change, it may become a problem in South Korea in the near future. Research on vaccines for dengue fever and outbreak preparedness are currently insufficient. In addition, because there are no appropriate animal models, controversial results from vaccine efficacy assessments and clinical trials have been reported. Therefore, to study the mechanism of dengue fever and test the immunogenicity of vaccines, an appropriate animal model is urgently needed. In addition to mouse models, more suitable models using animals that can be humanized will need to be constructed. In this report, we look at the current status of model animal construction and discuss which models require further development. PMID:28775974

The collective mobility of active matter (self-propelled objects that transduce energy into mechanical work to drive their motion, most commonly through fluids) constitutes a new frontier in science and achievable technology. This review surveys the current status of the research field, what kinds of new scientific problems can be tackled in the short term, and what long-term directions are envisioned. We focus on: (1) attempts to formulate design principles to tailor active particles; (2) attempts to design principles according to which active particles interact under circumstances where particle-particle interactions of traditional colloid science are augmented by a family of nonequilibrium effects discussed here; (3) attempts to design intended patterns of collective behavior and dynamic assembly; (4) speculative links to equilibrium thermodynamics. In each aspect, we assess achievements, limitations, and research opportunities.

Information about water quality is vital to ensure long-term availability and sustainability of water that is safe for drinking and recreation and suitable for industry, irrigation, fish, and wildlife. Protecting and enhancing water quality is a national priority, requiring information on water-quality status and trends, progress toward clean water standards, continuing problems, and emerging challenges. In this brief review, we discuss U.S. Geological Survey assessments of nutrient pollution, pesticides, mixtures of organic wastewater compounds (known as emerging contaminants), sediment-bound contaminants (like lead and DDT), and mercury, among other contaminants. Additionally, aspects of land use and current and emerging challenges associated with climate change are presented. Climate change must be considered, as water managers continue their efforts to maintain sufficient water of good quality for humans and for the ecosystem.

Toward Clarity in Clinical Vitamin D Status Assessment: 25(OH)D Assay Standardization.

PubMed

Binkley, Neil; Carter, Graham D

2017-12-01

Widespread variation in 25-hydroxyvitamin D (25(OH)D) assays continues to compromise efforts to develop clinical and public health guidelines regarding vitamin D status. The Vitamin D Standardization Program helps alleviate this problem. Reference measurement procedures and standard reference materials have been developed to allow current, prospective, and retrospective standardization of 25(OH)D results. Despite advances in 25(OH)D measurement, substantial variability in clinical laboratory 25(OH)D measurement persists. Existing guidelines have not used standardized data and, as a result, it seems unlikely that consensus regarding definitions of vitamin D deficiency, inadequacy, sufficiency, and excess will soon be reached. Until evidence-based consensus is reached, a reasonable clinical approach is advocated. Copyright © 2017 Elsevier Inc. All rights reserved.

Developing Discontinuous Galerkin Methods for Solving Multiphysics Problems in General Relativity

Multi-messenger observations of the merger of black hole-neutron star and neutron star-neutron star binaries, and of supernova explosions will probe fundamental physics inaccessible to terrestrial experiments. Modeling these systems requires a relativistic treatment of hydrodynamics, including magnetic fields, as well as neutrino transport and nuclear reactions. The accuracy, efficiency, and robustness of current codes that treat all of these problems is not sufficient to keep up with the observational needs. We are building a new numerical code that uses the Discontinuous Galerkin method with a task-based parallelization strategy, a promising combination that will allow multiphysics applications to be treated both accurately and efficiently on petascale and exascale machines. The code will scale to more than 100,000 cores for efficient exploration of the parameter space of potential sources and allowed physics, and the high-fidelity predictions needed to realize the promise of multi-messenger astronomy. I will discuss the current status of the development of this new code.

At Intermountain Healthcare (Intermountain), executive clinical content experts are responsible for disseminating consistent evidence-based clinical content throughout the enterprise at the point-of-care. With a paper-based system it was difficult to ensure that current information was received and was being used in practice. With electronic information systems multiple applications were supplying similar, but different, vendor-licensed and locally-developed content. These issues influenced the consistency of clinical practice within the enterprise, jeopardized patient and clinician safety, and exposed the enterprise and its employees to potential financial penalties. In response to these issues Intermountain is developing a knowledge management infrastructure providing tools and services to support clinical content development, deployment, maintenance, and communication. The Intermountain knowledge management philosophy includes strategies guiding clinicians and consumers of health information to relevant best practice information with the intention of changing behaviors. This paper presents three case studies describing different information management problems identified within Intermountain, methods used to solve the problems, implementation challenges, and the current status of each project.

There is an increasing pressure on the construction industry to reduce costs and improve the quality of our environment. The fact is that both of these goals can be achieved at the same time. Although construction and demolition (C&D) constitutes a major source of waste in terms of volume and weight, its management and recycling efforts have not yet seen the light in Kuwait. This study focuses on recycling efforts leading to the minimization of the total C&D waste that is currently landfilled in Kuwait. This paper presents the current status of C&D waste disposal system in Kuwait and identifies the potential problems to the environment, people and economy. Then, it investigates alternative solutions to manage and control this major type of waste in an economically efficient and environmentally safe manner. Next, the paper describes the feasibility of establishing a C&D waste recycling facility in Kuwait. It concludes by highlighting the major benefits and bottleneck problems with such a recycling facility.

Suicide during pregnancy and postpartum is a tragic event for the victim and profoundly impacts the baby, the family and the community. Prior efforts to study risks for pregnancy-associated suicide have been hampered by the lack of data sources which capture pregnancy and delivery status of victims. Introduction of the United States National Violent Death Reporting System (NVDRS) offers new insights into violent deaths by linking multiple data sources and allowing better examination of psychosocial risk factors. The analysis used data from 17 states reporting to the NVDRS from 2003 to 2007 to evaluate suicide patterns among pregnant, postpartum, and nonpregnant or postpartum women. Demographic factors, mental health status, substance use, precipitating circumstances, intimate partner problems and suicide methods were compared among groups. The 2083 female suicide victims of reproductive age demonstrated high prevalence of existing mental health diagnosis and current depressed mood, with depressed mood significantly higher among postpartum women. Substance use and presence of other precipitating factors were high and similar among groups. Intimate partner problems were higher among pregnant and postpartum victims. Postpartum women were more likely to die via asphyxia as cause of death compared to poisoning or firearms. These findings describe important mental health, substance use and intimate partner problems seen with pregnancy-associated suicide. The study highlights mental health risk factors which could potentially be targeted for intervention in this vulnerable population. Copyright © 2012 Elsevier Inc. All rights reserved.

Background Addiction is one of the complicated problems in Iranian young population. The social and cultural dimensions of this social disease are less considered. So considering socio-cultural and environmental resources, this study investigated the substructures of addiction according to the viewpoints of high-school students of Kerman, Iran in 2007-2008. Methods This qualitative study accomplished in ten high schools through a one-day problem finding workshop and continued until data saturation. The resulted terms and phrases were analyzed by content analysis. To assure about the validity and reliability, the outputs reviewed by workshops participants, and classification and codification of the data were executed separately by two experts. Findings A total of 212 students, 45.3% girls and 54.7% boys, participated in the study. The students introduced the followings as the addiction substantial fundaments: lack of knowledge, positive attitude and interpretation of addiction as a value, family or friends' habit, economy status, psycho-personality problems and availability. Rules infirmity or non-implementation of the current rules enforcement, geographical status and addiction as a conspiracy were also observed in students’ statements. Conclusion The positive attitudes and historical roots of addiction along with the process of changing the values caused the growth of drug addiction in young population which could neutralize the security measures, legislations policy and even the knowledge. Therefore, intensification of personal protective factors and culturalization addressed for improving inner layers of values are recommended. PMID:24494110

To test the hypothesis that the association previously reported between moderate alcohol use and better cognition is an artefact of confounding by (a) higher premorbid education and socioeconomic status; (b) a lifestyle of moderation (using smoking as a risk marker); and (c) decreased alcohol consumption in people with physical illnesses. Data were analysed from people aged 60-74 years interviewed for the 2000 British National Psychiatric Morbidity Survey, representative of people living in private homes. Alcohol use information was available for 1985 (98.9%) of the eligible participants, of whom 1735 (87.4%) who drank moderately or abstained were included in the analyses. Our main outcome measures were the Alcohol Use Disorders Identification Test (AUDIT), the Telephone Interview for Cognitive Status Screen for Cognitive Impairment and the National Adult Reading Test to measure crystallised (premorbid) intelligence. Our physical health measures were the number of prescribed medications and physical illness reported, and the 12 item Short Form Health Survey's Physical Component Score. The relationship between current cognition and alcohol use was reduced and no longer significant after considering premorbid intelligence or physical health. In our final model, the significant predictors of current cognition among non-problem drinkers were: age (B = -0.13, -0.18 to -0.08; p<0.001) and crystallised intelligence (B = 0.14, 0.12 to 0.17; p<0.001). Smoking was not associated with cognition. In people who were not problem drinkers, higher alcohol intake was not associated with improved current cognition after controlling for premorbid intelligence and physical health. Our findings suggest that, despite previous suggestions, moderate alcohol consumption does not protect older people from cognitive decline.

This study compared and contrasted personal characteristics, tobacco use (cigarette and water pipe smoking), and health states in Chaldean, Arab American and non-Middle Eastern White adults attending an urban community service center. The average age was 39.4 (SD = 14.2). The three groups differed significantly (P < .006) on ethnicity, age, gender distribution, marital status, language spoken, education, employment, and annual income. Current cigarette smoking was highest for non-Middle Eastern White adults (35.4%) and current water pipe smoking was highest for Arab Americans (3.6%). Arab Americans were more likely to smoke both cigarettes and the narghile (4.3%). Health problems were highest among former smokers in all three ethnic groups. Being male, older, unmarried, and non-Middle Eastern White predicted current cigarette smoking; being Arab or Chaldean and having less formal education predicted current water pipe use.

Those who are socioeconomically disadvantaged and people with emotional problems have a poorer prognosis for cardiovascular disease. The authors wanted to examine: (1) what effect household income, emotional status, high-risk smoking status, and severity of heart disease had on the ability of individuals to make dietary and exercise improvements after heart disease and (2) to what extent unfavourable lifestyle outcomes among disadvantaged people were mediated by motivational problems. A two-year follow-up study of the combined cohorts of a randomized controlled trial. Level of exercise and present dietary habits were measured at inclusion and after 6 and 24 months. Different motivational factors and emotional distress were measured during rehabilitation. Autonomous self-regulation was lowest among smokers (b = -0.31, p = 0.02) and female participants (b = 0.39, p = 0.004). Participants with high scores of emotional distress predicted lower motivation for all the measures. We found no association between socioeconomic status (household income) and the ability to perform lifestyle changes. Current smoking status predicted lower ability to obtain lifestyle changes on all measures. Emotional distress was related to lower ability to increase physical activity at 6 months' but not at 24 months' follow-up. The mediating effects of motivational factors were insignificant. The results of this study do not support the suspicion that preventive efforts accentuate the socioeconomic differences in cardiovascular health. Health-promotive efforts after heart disease should safeguard that high-risk groups such as smokers are not discouraged from improving their lifestyle in other areas.

2008-01-01

Objective The current review describes how the health status profile of people with fibromyalgia (FM) compares to that of people in the general population and patients with other health conditions. Methods A review of 37 studies of FM that measured health status with the 36-item Medical Outcomes Study Short-Form Health Survey (SF-36) or the 12-item Short-Form Health Survey (SF-12). Results Studies performed worldwide showed that FM groups were significantly more impaired than people in the general population on all eight health status domains assessed. These domains include physical functioning, role functioning difficulties caused by physical problems, bodily pain, general health, vitality (energy vs. fatigue), social functioning, role functioning difficulties caused by emotional problems and mental health. FM groups had mental health summary scores that fell 1 standard deviation (SD) below the general population mean, and physical health summary scores that fell 2 SD below the general population mean. FM groups also had a poorer overall health status compared to those with other specific pain conditions. FM groups had similar or significantly lower (poorer) physical and mental health status scores compared to those with rheumatoid arthritis, osteoarthritis, osteoporosis, systemic lupus erythematosus, myofacial pain syndrome, primary Sjögren's syndrome and others. FM groups scored significantly lower than the pain condition groups mentioned above on domains of bodily pain and vitality. Health status impairments in pain and vitality are consistent with core features of FM. Conclusions People with FM had an overall health status burden that was greater in magnitude compared to people with other specific pain conditions that are widely accepted as impairing. Review Criteria Studies in this review were identified through a search of electronic databases (MEDLINE: 1990–2006; EMBASE: 1990–2006). Search terms included: ‘fibromyalgia’, ‘health status’, ‘quality of life’, ‘SF-36’ and ‘SF-12’. Reference lists from published articles were also searched. Studies were selected if they were published in the English language between 1990 and (March) 2006 and assessed health status with a validated version of the SF-36 or the SF-12. Message for the Clinic Although FM is a controversial construct, studies performed worldwide showed that the health status profile of people with FM was remarkably consistent. People with FM had significant impairments in both mental and physical health status domains. People with FM had a poorer overall health status than people with specific pain conditions that are widely accepted as impairing. PMID:18039330

Depressive disorders in adolescents and young adults may have serious developmental and functional consequences, such as academic failure or persistent psychosocial problems. University students are affected by specific agents which may play a role in the onset of depression. The problem of student depression is particularly important in Poland because of a recent increase in student numbers, therefore, the aim of the presented study was to evaluate the prevalence of the risk of depression and suicidal thoughts among university students in Poznan, Poland, and to analyze the role of gender, current living arrangements, background (rural/small town or urban permanent place of residence), and reported financial status. 1,065 respondent students, mean age 21.1 years, 72% of whom were females, anonymously answered a questionnaire on the risk of depression (Kutcher's KADS) and a demographics survey. The obtained data were then analyzed statistically with the SPSS programme. 6.1 subjects were at risk of depression while 1.6 % of them had suicidal thoughts. Among analyzed determinants, perceived financial status and student's background (permanent place of residence) were found to have a statistically significant influence on the risk of depression. Students with rural/small town background and/or lower rather than good reported financial status are more likely to become depressed.

Open problems in mathematical physics

2017-09-01

We present a list of open questions in mathematical physics. After a historical introduction, a number of problems in a variety of different fields are discussed, with the intention of giving an overall impression of the current status of mathematical physics, particularly in the topical fields of classical general relativity, cosmology and the quantum realm. This list is motivated by the recent article proposing 42 fundamental questions (in physics) which must be answered on the road to full enlightenment (Allen and Lidstrom 2017 Phys. Scr. 92 012501). But paraphrasing a famous quote by the British football manager Bill Shankly, in response to the question of whether mathematics can answer the Ultimate Question of Life, the Universe, and Everything, mathematics is, of course, much more important than that.

Rijsdijk, Case L.

A brief review of the issues affecting the current status of science education in general, and astronomy education in particular, is given. The paper looks at the present situation at primary, secondary and tertiary levels. South Africa has unique educational problems and the initiatives by local observatories and universities at school level are described. The problems encountered by the South African Astronomical Observatory (SAAO) Science Education Initiative (SEI) are typical, as is the SEI approach to addressing some of these. The experience of the SEI is described, as are some of the resources developed by them for primary and secondary schools. Finally a brief look is taken at future developments, in particular, ways in which the Southern African Large Telescope (SALT) can contribute to astronomy and science education.

To examine separate mediational models linking (a) menarcheal status or (b) pubertal timing to internalizing and externalizing problems through competence. This study involved cross-sectional analyses of 262 adolescent girls (age: 11-17 years; mean = 14.93, standard deviation = 2.17) enrolled in a longitudinal study examining the association of psychological functioning and smoking with reproductive and bone health. Measures of menarcheal status (pre/post), pubertal timing (early, on-time, or late), internalizing and externalizing behavior, and perceived competence (parent and adolescent report) were obtained. Structural equation modeling was used for analyses. Perceived competence was found to fully mediate the association between menarcheal status and parent report of internalizing and externalizing problems. For adolescent report, there was a full mediation effect for internalizing problems but a partial mediation effect for externalizing problems. Being menarcheal was related to lower competence, which was in turn related to higher internalizing and externalizing problems. Models including pubertal timing were not significant. Perceived competence is important in understanding the associations between menarcheal status and internalizing and externalizing problems. Interventions targeting competence, particularly in postmenarcheal girls, may reduce or prevent problem behaviors. Copyright © 2011 Society for Adolescent Health and Medicine.

2013-01-01

Despite the latest technological advances in radiotherapy, cancer control is still challenging for several tumour sites. The survival rates for the most deadly cancers, such as ovarian and pancreatic, have not changed over the last decades. The solution to the problem lies in the change of focus: from local treatment to systemic therapy. The aim of this paper is to present the current status as well as the gaps in radiotherapy and, at the same time, to look into potential solutions to improve cancer control and survival. The currently available advanced radiotherapy treatment techniques have been analysed and their cost-effectiveness discussed. The problem of systemic disease management was specifically targeted. Clinical studies show limited benefit in cancer control from hadron therapy. However, targeted therapies together with molecular imaging could improve treatment outcome for several tumour sites while controlling the systemic disease. The advances in photon therapy continue to be competitive with the much more expensive hadron therapy. To justify the cost effectiveness of proton/heavy ion therapy, there is a need for phase III randomised clinical trials. Furthermore, the success of systemic disease management lies in the fusion between radiation oncology technology and microbiology.

Emotional and Behavioral Problems in Migrant Children and Adolescents in American Countries: A Systematic Review.

2015-08-01

The present review postulates the current mental health status in migrant children and adolescents in the North American continent. 35 studies published from 2009 to 2013 chosen from a systematic literature research were included. Almost all studies were conducted in the United States and Canada. From the perspective of selection effect, migration as a risk factor was not proven. The migration process perspective could have underestimated a higher danger of problem behavior in second-generation migrant children. Comparing native and migrant children, balanced results in problem behavior were reported, but the Asian migrant group was at higher risk of developing mental disorders. Family-based risk factors were offered: high acculturation stress, low English language competence, language brokering, discrepancies in children's and parent's cultural orientation, the non-Western cultural orientation, e.g., collectivistic, acceptance feelings of parents, or harsh parenting. However, the importance to support migrant families in the acculturation process becomes apparent.

Team play with a powerful and independent agent: a full-mission simulation study.

PubMed

Sarter, N B; Woods, D D

One major problem with pilot-automation interaction on modern flight decks is a lack of mode awareness; that is, a lack of knowledge and understanding of the current and future status and behavior of the automation. A lack of mode awareness is not simply a pilot problem; rather, it is a symptom of a coordination breakdown between humans and machines. Recent changes in automation design can therefore be expected to have an impact on the nature of problems related to mode awareness. To examine how new automation properties might affect pilot-automation coordination, we performed a full-mission simulation study on one of the most advanced automated aircraft, the Airbus A-320. The results of this work indicate that mode errors and "automation surprises" still occur on these advanced aircraft. However, there appear to be more opportunities for delayed or missing interventions with undesirable system activities, possibly because of higher system autonomy and coupling.

Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, Λ CDM. This is motivated by a range of apparently serious theoretical issues, involving such questions as the cosmological constant problem, the particle nature of dark matter, the validity of general relativity on large scales, the existence of anomalies in the CMB and on small scales, and the predictivity and testability of the inflationary paradigm. In this paper, we summarize the current status of Λ CDM as a physical theory, and review investigations into possible alternatives along a number of different lines, with a particular focus on highlighting the most promising directions. While the fundamental problems are proving reluctant to yield, the study of alternative cosmologies has led to considerable progress, with much more to come if hopes about forthcoming high-precision observations and new theoretical ideas are fulfilled.

Educational outcomes associated with childhood obesity in the United States: cross-sectional results from the 2011–2012 National Survey of Children’s Health

PubMed Central

2015-01-01

Background Past research examining the effects of childhood obesity has largely focused on its projected effects into adulthood. However, there is emerging evidence that childhood obesity may have more immediate effects on school-related outcomes. We examine a range of educational attainment indicators to examine the possible pathway between obesity status and academic performance, while investigating the proximal effects of childhood obesity on health and utilization of health services, and whether these variables attenuate the relationship between obesity status and educational outcomes. Methods Data for the current study come from the 2011-2012 National Survey of Children’s Health, which details the impacts of childhood obesity on a range of outcomes among a nationally representative sample of children and adolescents aged 10-17 years (N=45,255). Educational outcomes (school absences, school problems, repeating a grade and school engagement) were modeled by logistic regression as a function of BMI, overall health status, health care utilization, and a range of sociodemographic variables. Results BMI status was significantly associated with all educational outcomes (p<0.001 for all), overall health status (p<0.001), and health care utilization (p=0.016). Prior to adjustment for covariates, obese children were significantly more likely to have school absences and school problems, to repeat a grade, and to have lower school engagement than non-overweight children. After adjustment for sociodemographic and health/healthcare variables, these outcomes remained significant for all but repeating a grade. The odds of having school problems, repeating a grade, and low school engagement that were associated with obesity were attenuated by the addition of sociodemographic variables into the model, while the addition of health and health care variables in the model decreased the odds of school absences. Conclusions This study provides evidence that increased weight status in children is associated with poorer educational outcomes. While recognizing that these are cross-sectional data, we suggest that 1) health-related and sociodemographic factors should be a focus point of intervention, and 2) a socio-structural approach including Coordinated School Health intervention is crucial to reducing childhood obesity and improving educational outcomes in this population.

Anxiety and depression frequently co-occur with borderline personality disorder. Relatively little research examined the presence of borderline personality features and its main domains (affective instability, identity problems, negative relationships and self-harm) in individuals with remitted and current anxiety and depression. Participants with current (n=597) or remitted (n=1115) anxiety and/or depression and healthy controls (n=431) were selected from the Netherlands Study of Depression and Anxiety. Assessments included the Personality Assessment Inventory - Borderline Features Scale and several clinical characteristics of anxiety and depression. Borderline personality features were more common in depression than in anxiety. Current comorbid anxiety and depression was associated with most borderline personality features. Anxiety and depression status explained 29.7% of the variance in borderline personality features and 3.8% (self-harm) to 31% (identity problems) of the variance in the four domains. A large part of the variance was shared between anxiety and depression but both disorders also explained a significant amount of unique variance. The severity of anxiety and depression and the level of daily dysfunctioning was positively associated with borderline personality features. Individuals with a longer duration of anxiety and depression showed more affective instability and identity problems. These findings suggest that patients with anxiety and depression may benefit from an assessment of personality pathology as it may have implications for psychological and pharmacological treatment.

Self-reported health status and access to health services in a sample of prisoners in Italy

PubMed Central

2011-01-01

Background Self-reported health status in underserved population of prisoners has not been extensively explored. The purposes of this cross-sectional study were to assess self-reported health, quality of life, and access to health services in a sample of male prisoners of Italy. Methods A total of 908 prisoners received a self-administered anonymous questionnaire pertaining on demographic and detention characteristics, self-reported health status and quality of life, access to health services, lifestyles, and participation to preventive, social, and rehabilitation programs. A total of 650 prisoners agreed to participate in the study and returned the questionnaire. Results Respectively, 31.6% and 43.5% of prisoners reported a poor perceived health status and a poor quality of life, and 60% admitted that their health was worsened or greatly worsened during the prison stay. Older age, lower education, psychiatric disorders, self-reported health problems on prison entry, and suicide attempts within prison were significantly associated with a perceived worse health status. At the time of the questionnaire delivery, 30% of the prisoners self-reported a health problem present on prison entry and 82% present at the time of the survey. Most frequently reported health problems included dental health problems, arthritis or joint pain, eye problems, gastrointestinal diseases, emotional problems, and high blood pressure. On average, prisoners encountered general practitioners six times during the previous year, and the frequency of medical encounters was significantly associated with older age, sentenced prisoners, psychiatric disorders, and self-reported health problems on prison entry. Conclusions The findings suggest that prisoners have a perceived poor health status, specific care needs and health promotion programs are seldom offered. Programs for correction of risk behaviour and prevention of long-term effects of incarceration on prisoners' health are strongly needed. PMID:21726446

Brief report: Affluence and college alcohol problems: the relevance of parent- and child-reported indicators of socioeconomic status.

PubMed

Harrell, Zaje A T; Huang, Jason L; Kepler, Dawn M

2013-10-01

A mediational model predicting alcohol problems was tested in a sample of college students (n = 130) and their parents (n = 115). The indirect effect of substance-use coping and the age of onset of alcohol use were examined in the relationship between socioeconomic status (SES) and alcohol problems. Findings indicated that parent-reported SES was associated with increased alcohol problems; the age of onset of alcohol use partially mediated this relationship. Substance-use coping was not a significant mediator in the model. Student-reported SES was not associated with alcohol problems. Implications for examining social status in relation to college drinking behaviors are discussed. Copyright © 2013 The Foundation for Professionals in Services for Adolescents.

In this paper, we review the status of social policy for the elderly in Ukraine since the fall of Communism and the breakup of the Soviet Union. We specifically address the problem of "rebuilding" an income and services policy for the at-risk elderly after the unraveling of the system that existed prior to the fall of Communism. Also, we address some existing problems faced by the elderly in the health care system. Within this context, we present a case study of the current status of long-term care policy for the elderly in one province of Ukraine, the eastern province of Zaporozhye, encompassing the industrial city of Zaporozhye on the Dnieper River. This case study particularly pays attention to current attempts to promote a social development process of long-term care services for the elderly. It examines recent developments with respect to public sector organizations and voluntary sector organizations that are trying to provide necessary services to the needy elderly. With respect to the voluntary sector, the paper pays particular attention to the American Jewish Joint Distribution Committee (JDC) model of a largely externally funded NGO that provides comprehensive and integrated social supports, while emphasizing local empowerment and the use of volunteers, for the needy Jewish population in the province of Zaporozhye. Based on our findings, we make some proposals regarding the improvement of income and services policy with respect to the elderly in Zaporozhye and Ukraine.

The aim of the study was to determine the prevalence of shisha smoking and associated factors among medical students in Malaysia. A cross-sectional study was conducted at the Management and Science University from December 2011 until March 2012. The questionnaire consisted of five sections including socio-demographic, social environment, knowledge about shisha, psychosocial factors, and personal shisha smoking behavior. Obtained data were analyzed using Statistical Package for the Social Sciences (SPSS 13). T-test was used to determine the relationships between shisha smoking and socio-demographic characteristic. A total number of 300 medical students participated in this study. Mean age was 22.5±2.5 years. The majority were female, Malay, single, from urban areas (67%, 54%, 97%, 73%; respectively). The prevalence of shisha smoking among medical students was found to be 20%. The study revealed that many students believed that shisha does not contains nicotine, carbon monoxide, does not lead to lung cancer, dental problems and does not lead to cardiovascular diseases (25%, 20.7%, 22.3%, 29%, 26.7%; respectively). Age and sex were found to be significantly associated with smoking shisha status among medical students (p=0.029, p<0.001; respectively). Furthermore, having parents, siblings and friends smokers of shisha were found to be significantly associated with shisha smoking status (p<0.001, p<0.001, p<0.001; respectively). Furthermore, family problems, problems with friends, financial problems and university life were found to significantly associated with shisha smoking status among medical students (p<0.001, p=0.002, p<0.001, p=0.002; respectively). There is a high prevalence of shisha smoking and a poor knowledge about its impact on health among medical students. More attention is needed to focus on medical education in this regard. The policies that are currently employed in order to reduce the cigarettes smoking should be applied to shisha smoking and shisha products.

Estimating Tissue Iron Burden: Current Status and Future Prospects

PubMed Central

Wood, John C.

2015-01-01

SUMMARY Iron overload is becoming an increasing problem as haemoglobinopathy patients gain greater access to good medical care and as therapies for myelodysplastic syndromes improve. Therapeutic options for iron chelation therapy have increased and many patients now receive combination therapies. However, optimal utilization of iron chelation therapy requires knowledge not only of the total body iron burden but the relative iron distribution among the different organs. The physiological basis for extrahepatic iron deposition is presented in order to help identify patients at highest risk for cardiac and endocrine complications. This manuscript reviews the current state of the art for monitoring global iron overload status as well as its compartmentalization. Plasma markers, computerized tomography, liver biopsy, magnetic susceptibility devices and magnetic resonance imaging (MRI) techniques are all discussed but MRI has come to dominate clinical practice. The potential impact of recent pancreatic and pituitary MRI studies on clinical practice are discussed as well as other works-in-progress. Clinical protocols are derived from experience in haemoglobinopathies but may provide useful guiding principles for other iron overload disorders, such as myelodysplastic syndromes. PMID:25765344

Kim, Dong-Sik; Kim, Hyun-Sun

2010-01-01

This study examined the association between early initiation of problem behaviors (alcohol drinking, cigarette smoking, and sexual intercourse) and suicidal behaviors (suicidal ideation and suicide attempts), and explored the effect of concurrent participation in these problem behaviors on suicidal behaviors among Korean adolescent males and females. Data were obtained from the 2006 Korean Youth Risk Behavior Survey, a nationally representative sample of middle and high school students (32,417 males and 31,467 females) in grades seven through twelve. Bivariate and multivariate logistic analyses were conducted. Several important covariates, such as age, family living structure, household economic status, academic performance, current alcohol drinking, current cigarette smoking, current butane gas or glue sniffing, perceived body weight, unhealthy weight control behaviors, subjective sleep evaluation, and depressed mood were included in the analyses. Both male and female preteen initiators of each problem behavior were at greater risk for suicidal behaviors than non-initiators, even after controlling for covariates. More numerous concurrent problematic behaviors were correlated with greater likelihood of seriously considering or attempting suicide among both males and females. This pattern was more clearly observed in preteen than in teen initiators although the former and latter were engaged in the same frequency of problem behavior. Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors.

The present study investigates physical health problems among patients with alcohol use disorders at alcohol treatment agencies in six European cities. The sample comprised 315 patients with a primary alcohol use disorder. Data were collected at admission to treatment using a structured research protocol, and ratings were made by a medically qualified physician subsequent to a physical examination of the patient. Physical health problems were extremely common: 79% of the sample had at least one problem, and 59% had two or more problems. Health problems were often serious, and 60% had at least one health problem that required treatment. The most common problems were gastrointestinal and liver disorders, but about a quarter of the sample had cardiovascular or neurological problems. Frequency of drinking, duration of alcohol use disorder, and severity of alcohol dependence were associated with increased physical morbidity. Current smoking status and age were also associated with poorer physical health. Older drinkers had more physical health problems although they were less severely alcohol dependent than their younger counterparts. The high prevalence of physical health problems among problem drinkers provides opportunities of screening for alcohol use disorders not only in specialist alcohol treatment services but also in other health-care settings. It is recommended that alcohol treatment agencies should provide a full routine health screen of patients at admission to treatment with provision or referral to appropriate treatment.

An active lifestyle and a good weight status are two major health determinants from a public health perspective. To evaluate the degree of association between physical activity, weight status and the emotional and mental health of Spanish schoolchildren. Mental health status was assessed through the Strengths and Difficulties Questionnaire (SDQ), also leisure time physical activity and body mass index (BMI) in a total of 6 803 children from 4 to 15 years participating in the Spanish National Health Survey 2006. The degree of association between. these variables was estimated by a multinomial logistic regression analysis. Among sedentary schoolchildren are more common mental health problems (OR 2.10), emotional problems (OR 1.84), conduct problems (OR 1.53), problems with peers (OR 2.35) and social relationship difficulties (OR 1.36). Obesity is associated with poor general mental health (OR 1.58), and obese schoolchildren show more often emotional problems (OR 1.52) and problems with peers (OR 2.43). In the Spanish schoolchildren, a healthy BMI is associated with increased mental well-being, although an active lifestyle is the best indicator of a good mental health status.

Antimicrobial resistance among Enterobacteriaceae in South America: history, current dissemination status and associated socioeconomic factors.

2014-04-01

South America exhibits some of the higher rates of antimicrobial resistance in Enterobactericeae worldwide. This continent includes 12 independent countries with huge socioeconomic differences, where the ample access to antimicrobials, including counterfeit ones, coexists with ineffective health systems and sanitation problems, favoring the emergence and dissemination of resistant strains. This work presents a literature review concerning the evolution and current status of antimicrobial resistance threats found among Enterobacteriaceae in South America. Resistance to β-lactams, fluoroquinolones and aminoglycosides was emphasized along with description of key epidemiological studies that highlight the success of specific resistance determinants in different parts of the continent. In addition, a discussion regarding political and socioeconomic factors possibly related to the dissemination of antimicrobial resistant strains in clinical settings and at the community is presented. Finally, in order to assess the possible sources of resistant bacteria, we compile the current knowledge about the occurrence of antimicrobial resistance in isolates in South American' food, food-producing animals and off-hospitals environments. By addressing that intensive intercontinental commerce and tourism neutralizes the protective effect of geographic barriers, we provide arguments reinforcing that globally integrated efforts are needed to decelerate the emergence and dissemination of antimicrobial resistant strains.

2014-01-01

Non-human primates (NHPs) are phylogenetically close to humans, with many similarities in terms of physiology, anatomy, immunology, as well as neurology, all of which make them excellent experimental models for biomedical research. Compared with developed countries in America and Europe, China has relatively rich primate resources and has continually aimed to develop NHPs resources. Currently, China is a leading producer and a major supplier of NHPs on the international market. However, there are some deficiencies in feeding and management that have hampered China’s growth in NHP research and materials. Nonetheless, China has recently established a number of primate animal models for human diseases and achieved marked scientific progress on infectious diseases, cardiovascular diseases, endocrine diseases, reproductive diseases, neurological diseases, and ophthalmic diseases, etc. Advances in these fields via NHP models will undoubtedly further promote the development of China’s life sciences and pharmaceutical industry, and enhance China’s position as a leader in NHP research. This review covers the current status of NHPs in China and other areas, highlighting the latest developments in disease models using NHPs, as well as outlining basic problems and proposing effective countermeasures to better utilize NHP resources and further foster NHP research in China.

The association between eczema and mental health problems in schoolchildren has been underexplored. We aimed to investigate this association with the validated questionnaires. Of 46,648 invited children, we analyzed 9954 (21.3%) in the 2nd to the 8th grades from the ToMMo Child Health Study conducted in 2014 and 2015, a cross-sectional survey in Miyagi Prefecture, Japan. We defined eczema status as "normal," "mild/moderate," or "severe," based on the presence of persistent flexural eczema and sleep disturbance, according to the International Study of Asthma and Allergies in Childhood (ISAAC) Eczema Symptom Questionnaire. Clinical ranges of Strengths and Difficulties Questionnaire (SDQ) total difficulties scores and four SDQ subcategories of emotional symptoms, conduct problems, hyperactivity/inattention, and peer problems were defined as scores ≥16, ≥5, ≥5, ≥7, and ≥5, respectively. The mean SDQ total difficulties score significantly increased as eczema status worsened (all P ≤ 0.004 for trend). The OR of scores in the clinical range for SDQ total difficulties were 1.51 (95% CI, 1.31-1.74) for mild/moderate eczema and 2.63 (95% CI, 1.91-3.63) for severe eczema (P < 0.001 for trend), adjusted for sex, school grade, current wheeze, and disaster-related factors, using normal eczema as a reference. The association between severity of eczema and four SDQ subcategories showed a similar trend (all P ≤ 0.017 for trend). We found a significant association between severity of eczema and mental health problems. The presence of eczema was associated with four SDQ subcategories.

Metabolomics for Assessment of Nutritional Status

PubMed Central

Zivkovic, Angela M.; German, J. Bruce

2010-01-01

Purpose of review The current rise in diet-related diseases continues to be one of the most significant health problems facing both the developed and the developing world. The use of metabolomics – the accurate and comprehensive measurement of a significant fraction of important metabolites in accessible biological fluids – for the assessment of nutritional status, is a promising way forward. The basic toolset, targets, and knowledge are all being developed in the emerging field of metabolomics, yet important knowledge and technology gaps will need to be addressed in order to bring such assessment to practice. Recent findings Dysregulation within the principal metabolic organs (e.g. intestine, adipose, skeletal muscle, liver) are at the center of a diet-disease paradigm that includes metabolic syndrome, type 2 diabetes, and obesity. The assessment of both essential nutrient status, and the more comprehensive systemic metabolic response to dietary, lifestyle, and environmental influences (e.g. metabolic phenotype) are necessary for the evaluation of status in individuals that can identify the multiple targets of intervention needed to address metabolic disease. Summary The first proofs of principle building the knowledge to bring actionable metabolic diagnostics to practice through metabolomics are now appearing. PMID:19584717

Self-perception of disability and prospects for employment among U.S. veterans.

PubMed

Griffin, Christopher L; Stein, Michael Ashley

2015-01-01

Barriers to employment in the civilian labor force are increasingly difficult problems for returning veterans with disabilities. Reduced self-perception of disability status because of predominant military norms can be particularly harmful to reintegration efforts. We analyze rates of self-identified and externally determined disability status among U.S. veterans. Evidence of a lower self-report rate would confirm the hypothesis that armed forces culture might hold back truly deserving veterans from seeking the benefits owed, including specialized employment training programs. We use data from the Current Population Survey Veterans Supplement over the sample period 1995-2010 on disability status and associated demographic characteristics to present descriptive measures and limited statistical inference. Over the entire sample period, federal agencies considered 29% of the survey respondents to have a service-connected disability versus a 9% self-identification rate. The rate of more severe service-connected disabilities has risen steadily, while less drastic disability rates have fallen. Non-white respondents and those with lower education levels were less likely to self-identify. Large disparities in internal and external disability status identification raise questions about targeting soldiers re-entering the labor force. Employment policy should focus on overcoming negative cultural stereotypes and encouraging self-identification.

Nutrition situation in Latin America and the Caribbean: current scenario, past trends, and data gaps.

2016-08-01

To determine the current nutritional status in Latin America and the Caribbean (LAC) and identify data gaps and trends in nutrition surveillance. A systematic Internet search was conducted to identify official sources that allowed for monitoring of LAC countries' nutritional status, including progress toward World Health Organization Global Nutrition Targets 2025. Reports from national nutrition surveillance systems and reports on nationally representative surveys were collected and collated to 1) analyze nutritional status, based on life-course anthropometric indicators and biomarkers, and 2) identify gaps in data availability and trends in nutritional deficiencies. Information on iron, vitamin A, iodine, folate, and vitamin B12 deficiency was also collected and collated. Twenty-two of the 46 LAC countries/territories (48%) had information on undernutrition (stunting, underweight, and wasting) in children under 5 years old and women of reproductive age (WRA). Seventeen countries (38%) had information on anemia in children under 5 years old and WRA, and 12 (27%) had information on anemia in pregnant women. Although overall nutritional status has improved in the past few decades in all countries in the region, some LAC countries still had a high prevalence of stunting and anemia in children and WRA. Overweight affected at least 50% of WRA in nine countries with available data, and was increasing in children. Data for school-age children, adolescents, adult males, and older adults were scarce in the region. Overall nutritional status has improved in the LAC countries with available information, but more efforts are needed to scale up nutrition-sensitive and nutrition-specific interventions to tackle malnutrition in all its forms, as stunting, anemia, and vitamin A deficiency are still a public health problem in many countries, and overweight is an epidemic. Nutrition information systems are weak in the region, and countries need to strengthen their capacity to monitor nutritional status indicators.

Marginal regression approach for additive hazards models with clustered current status data.

PubMed

Su, Pei-Fang; Chi, Yunchan

2014-01-15

Current status data arise naturally from tumorigenicity experiments, epidemiology studies, biomedicine, econometrics and demographic and sociology studies. Moreover, clustered current status data may occur with animals from the same litter in tumorigenicity experiments or with subjects from the same family in epidemiology studies. Because the only information extracted from current status data is whether the survival times are before or after the monitoring or censoring times, the nonparametric maximum likelihood estimator of survival function converges at a rate of n(1/3) to a complicated limiting distribution. Hence, semiparametric regression models such as the additive hazards model have been extended for independent current status data to derive the test statistics, whose distributions converge at a rate of n(1/2) , for testing the regression parameters. However, a straightforward application of these statistical methods to clustered current status data is not appropriate because intracluster correlation needs to be taken into account. Therefore, this paper proposes two estimating functions for estimating the parameters in the additive hazards model for clustered current status data. The comparative results from simulation studies are presented, and the application of the proposed estimating functions to one real data set is illustrated. Copyright © 2013 John Wiley & Sons, Ltd.

Current Mysteries of AGB Stars

NASA Astrophysics Data System (ADS)

Tout, Christopher A.

We pay tribute to the memory of Manuel Forestini by recalling his contributions to astronomy and in particular to our understanding of AGB stars. We critically examine the current status of this understanding amongst the community and deduce that major uncertainties arise in the physics of convection, any form of extra mixing beyond convection and the mass loss from the stellar surface. Coupled with these are numerical difficulties associated with the short and similar timescales for structural changes, nuclear burning and convective mixing. We hope that workshops such as this will promote familiarity amongst our diverse international community young and old and so promote effective dialogue that will ultimately lead to solutions to our problems along with the creation of new ones for the future!

The effects of adolescent intimate partner violence on women's educational attainment and earnings.

2013-11-01

Intimate partner violence (IPV) is a serious, widespread problem that negatively affects women's lives, including their economic status. The current study explored whether the financial harm associated with IPV begins as early as adolescence. With longitudinal data from a sample of 498 women currently or formerly receiving welfare, we used latent growth curve modeling to examine the relationships between adolescent IPV, educational attainment, and women's earnings. We found that women who had been victimized by a partner during adolescence obtained less education compared with nonvictimized women, with victimization indirectly influencing women's earnings via educational attainment. The findings support the need for intervention strategies aimed at preventing IPV and promoting women's educational and career development over the life course.

Opisthorchiasis caused by Opisthorchis viverrini (O. viverrini) remains a major public health problem in many parts of Southeast Asia including Thailand, Lao PDR, Vietnam and Cambodia. The infection is associated with a number of hepatobiliary diseases, including cholangitis, obstructive jaundice, hepatomegaly, cholecystitis, chole-lithiasis and cholangiocarcinoma. The liver fluke infection was induced by eating raw or uncooked fish products that is the tradition and popular in the northeastern and northern region, particularly in rural areas of Thailand. Health education programs to prevent and control opisthorchiasis are still required in high-risk areas.

1987-01-01

In cooperation with the International Landsat community, and through the Landsat Technical Working Group (LTWG), NOAA is assembling information about the status of the Worldwide Landsat Archive. During LTWG 9, member nations agreed to participate in a survey of International Landsat data holding and of their archive experiences with Landsat data. The goal of the effort was two-fold; one, to document the Landsat archive to date, and, two, to ensure that specific nations' experience with long-term Landsat archival problems were available to others. The survey requested details such as amount of data held, the format of the archive holdings by Spacecraft/Sensor, and acquisition years; the estimated costs to accumulated process, and replace the data (if necessary); the storage space required, and any member nation's plans that would establish the insurance of continuing quality. As a group, the LTWG nations are concerned about the characteristics and reliability of long-term magnetic media storage. Each nation's experience with older data retrieval is solicited in the survey. This information will allow nations to anticipate and plan for required changes to their archival holdings. Also solicited were reports of any upgrades to a nation's archival system that are currently planned and all results of attempts to reduce archive holdings including methodology, current status, and the planned access rates and product support that are anticipated for responding to future archival usage.

TIIMS is used during the inspection phases of every mission to provide quick visual feedback, detailed inspection data, and determination to the mission management team. This system consists of a visual Web page interface, an SQL database, and a graphical image generator. These combine to allow a user to ascertain quickly the status of the inspection process, and current determination of any problem zones. The TIIMS system allows inspection engineers to enter their determinations into a database and to link pertinent images and video to those database entries. The database then assigns criteria to each zone and tile, and via query, sends the information to a graphical image generation program. Using the official TIPS database tile positions and sizes, the graphical image generation program creates images of the current status of the orbiter, coloring zones, and tiles based on a predefined key code. These images are then displayed on a Web page using customized JAVA scripts to display the appropriate zone of the orbiter based on the location of the user's cursor. The close-up graphic and database entry for that particular zone can then be seen by selecting the zone. This page contains links into the database to access the images used by the inspection engineer when they make the determination entered into the database. Status for the inspection zones changes as determinations are refined and shown by the appropriate color code.

Alzheimer's disease (AD) shows a marked presence of physiologic changes and the start or aggravation of underlying diseases such as physical frailty in diverse anatomical regions. It is believed to have a particularly harmful effect on the health of the foot. We examined the foot health status in older persons with AD, with a specific focus on the extent to which people with AD may be using inadequate footwear in old age. Seventy-three community-dwelling people with probable, mild to moderate AD aged 65-95 years were recruited from a center of excellence for AD. A single trained physician evaluated health status and foot conditions. Current shoe and foot length and width measurements were taken using a calibrated Brannock device. The results indicate that sixty-five participants (89.04%) suffered from feet problems. Also, only twenty-two subjects (30.14%) used the correct shoes in width and size related with the morphology of their feet. Fifty-one participants (69.86%) were using incorrect shoes in length or width. The present study revealed that peoples with AD had a high presence of foot health problems. Also, the use of inappropriate shoes revealed measurable differences of association between shoe size and the morphology of the foot.

As HIV is currently a chronic and manageable disease, an increasing amount of people living with HIV (PLHIV) are (again) active on the labour market. Since research on this topic is scarce, this study aimed to explore experiences of PLHIV in the workplace, especially concerning disclosure and adherence to antiretroviral therapy. A questionnaire was developed and validated in collaboration with Sensoa (Flemish expertise centre for sexual health) and participants were recruited using flyers and announcements on websites. A total of 54 PLHIV completed the questionnaire, among whom 50 (92·6%) males. Half of the participants did not disclose their HIV status in the workplace, mostly due to being afraid of social or professional consequences. Those who disclosed, reported no changes in the workplace or even reported receiving more empathy. A minority of participants have to take antiretroviral medication at work and they reported no particular problems related to medication intake. Despite improved solidarity and information campaigns, many PLHIV still do not disclose their HIV status in the workplace, most frequently due to fear for discrimination. More actions are warranted, as well as addressing possible self-stigma. Adherence to antiretroviral therapy in the workplace posed little or no problems.

In three provinces of the Philippines (Quezon, Northern Samar and Zamboanga del Sur), 11,378 children between 6 and 83 months of age were examined for signs of xerophthalmia and weighed to determine weight-for-age status. Xerophthalmia prevalence ranged from 1.6% to 4.4% for nightblindness and 0.6% to 2.7% for Bilot's spots in the three provinces indicating a serious vitamin A deficiency problem. These levels contrast sharply with the recent national xerophthalmia prevalence (0.7% for night blindness and 0.2% for Bitot's spots). There was a preponderance of mild xerophthalmia among males, and among children 4-6 years of age. No consistent association between weight-for-age status and xerophthalmia was found. The study recommends the universal distribution of vitamin A to children in high-prevalence regions, rather than the current practice of providing vitamin A supplements to moderately and severely underweight children identified through the annual village-based child weighing sessions, to ensure reaching children most at risk for xerophthalmia. The study also suggests the need for regional vitamin A assessments to identify areas endemic for vitamin A deficiency because the aggregate national prevalence may mask a more serious localized problem.

Global iodine nutrition: Where do we stand in 2013?

Dietary iodine intake is required for the production of thyroid hormone. Consequences of iodine deficiency include goiter, intellectual impairments, growth retardation, neonatal hypothyroidism, and increased pregnancy loss and infant mortality. In 1990, the United Nations World Summit for Children established the goal of eliminating iodine deficiency worldwide. Considerable progress has since been achieved, largely through programs of universal salt iodization. Approximately 70% of all households worldwide currently have access to adequately iodized salt. In 2013, as defined by a national or subnational median urinary iodine concentration of 100-299 μg/L in school-aged children, 111 countries have sufficient iodine intake. Thirty countries remain iodine-deficient; 9 are moderately deficient, 21 are mildly deficient, and none are currently considered severely iodine-deficient. Ten countries have excessive iodine intake. In North America, both the United States and Canada are generally iodine-sufficient, although recent data suggest pregnant U.S. women are mildly iodine-deficient. Emerging issues include discrepancies between urinary iodine status in pregnant women compared to school-aged children in some populations, the problem of re-emerging iodine deficiency in parts of the developed world, the importance of food industry use of iodized salt, regions of iodine excess, and the potential effects of initiatives to lower population sodium consumption on iodine intake. Although substantial progress has been made over the last several decades, iodine deficiency remains a significant health problem worldwide and affects both industrialized and developing nations. The ongoing monitoring of population iodine status remains crucially important, and particular attention may need to be paid to monitoring the status of vulnerable populations, such as pregnant women and infants. There is also need for ongoing monitoring of iodized salt and other dietary iodine sources in order to prevent excess as well as insufficient iodine nutrition. Finally, it will be essential to coordinate interventions designed to reduce population sodium intake with salt iodization programs in order to maintain adequate levels of iodine nutrition as salt intake declines.

Role of Various Entropies in the Black Hole Information Loss Problem

We discuss the current status of the black hole information loss paradox and propose a plan for its solution based on analogies with solid state physics and the irreversibility problem. In a recent paper Hawking has argued that there is no information loss in black holes in asymptotically AdS spacetimes. We remind that there are several types of information (entropy) in statistical physics - fine grained (microscopic) and coarse grained (macroscopic) ones which behave differently under unitary evolution. We suggest that the coarse grained information of the rest of the Universe is lost while fine grained information is preserved. A possibility to develop in quantum gravity an analogue of the Bogoliubov derivation of the irreversible Boltzmann and Navier - Stokes equations from the reversible mechanical equations is discussed.

Objectives. This study investigated whether health problems among poor mothers of chronically ill children affect their ability to obtain and maintain employment. Methods. Mothers of children with chronic illnesses were surveyed at clinical and welfare agency sites in San Antonio, Tex. Results. There were distinct health differences according to mothers’ TANF and employment status. Mothers without TANF experience reported better physical and mental health and less domestic violence and substance use than did those who had TANF experience. Those not currently working had higher rates of physical and mental health problems. Conclusions. Poor maternal health is associated with need for cash assistance and health insurance. Policymakers must recognize that social policies promoting employment will fail if they do not address the health needs of poor women and children. PMID:12197974

Major technical issues involving the integration of distributed photovoltaics (PV) into electric utility systems are defined and their impacts are described quantitatively. An extensive literature search, interviews, and analysis yielded information about the work in progress and highlighted problem areas in which additional work and research are needed. The findings from the literature search were used to determine whether satisfactory solutions to the problems exist or whether satisfactory approaches to a solution are underway. It was discovered that very few standards, specifications, or guidelines currently exist that will aid industry in integrating PV into the utility system. Specific areas of concern identified are: (1) protection, (2) stability, (3) system unbalance, (4) voltage regulation and reactive power requirements, (5) harmonics, (6) utility operations, (7) safety, (8) metering, and (9) distribution system planning and design.

No studies to date have assessed whether recent young adult (aged 18-34) Latino immigrants' biological parents' histories of substance use problems (BPHSUP) in their country of origin predict their alcohol use problems at pre- and post-immigration to the United States (US). BPHSUP in their country of origin were assessed via interviews conducted by bilingual Latino researchers with recent Latino immigrants primarily from Cuba and Central and South America recruited through respondent-driven sampling at the time of their immigration to southeastern US. Three waves of data were collected to document Latino immigrants' severity of alcohol use problems at pre-immigration and 2 annual post-immigration follow-up assessments. BPHSUP+/- status was used as a predictor of Latinos' (N = 452; 45.8% female, 54.2% male) Alcohol Use Disorders Identification Test (AUDIT) scores at pre- and post-immigration with age, education, and income as covariates as wells as odds ratios for AUDIT classifications of hazardous use, harmful use, and dependence. BPHSUP+ status predicted Latino immigrants' higher AUDIT scores pre- and post-immigration by gender (P < .01) compared with Latino immigrants of BPHSUP- status, controlling for age, education, and income. BPHSUP+ status predicted odds ratios of 3.45 and 2.91 for AUDIT alcohol dependence classification for men and women, respectively. This study documents that BPHSUP+/- status in their country of origin predict their young adult Latino offspring's severity of alcohol use problems pre- and post-immigration. These results may inform (1) community-based health care providers to screen recent young adult Latino immigrants for their BPHSUP+/- status and severity of alcohol use problems to redirect trajectories away from alcohol use disorders toward more normative post-immigration outcomes through culturally relevant prevention services and (2) future research advantages of differential susceptibility theory. Implications for future research and the need for replication studies in other geographic regions of the US are discussed.

A small number of patients frequently using the emergency department (ED) account for a disproportionate amount of the total ED workload and are considered using this service inappropriately. The aim of this study was to identify prospectively personal characteristics and experience of organizational and relational dimensions of primary care that predict frequent use of ED. This study was conducted among parallel cohorts of the general population and primary care patients (N = 1,769). The measures were at baseline (T1), 12 (T2) and 24 months (T3): self-administered questionnaire on current health, health behaviours and primary care experience in the previous year. Use of medical services was confirmed using administrative databases. Mixed effect logistic regression modeling identified characteristics predicting frequent ED utilization. A higher likelihood of frequent ED utilization was predicted by lower socioeconomic status, higher disease burden, lower perceived organizational accessibility, higher number of reported healthcare coordination problems and not having a complete annual check-up, above and beyond adjustment for all independent variables. Personal characteristics such as low socioeconomic status and high disease burden as well as experience of organizational dimensions of primary care such as low accessibility, high healthcare coordination problems and low comprehensiveness of care are prospectively associated with frequent ED utilization. Interventions developed to prevent inappropriate ED visits, such as case management for example, should tailor low socioeconomic status and patients with high disease burden and should aim to improve experience of primary care regarding accessibility, coordination and comprehensiveness.

Growing numbers of reproductive-age US women with chronic physical disabilities (CPD) raise questions about their pregnancy experiences. Little is known about the health risks of women with versus without CPD by current pregnancy status. We analyzed cross-sectional, nationally-representative National Health Interview Survey data from 2006 to 2011, which includes 47,629 civilian, noninstitutionalized women ages 18-49. NHIS asks about specified movement difficulties, current pregnancy, and various health and health risk indicators, including tobacco use and body mass index (BMI). We used responses from eight movement difficulty and other questions to identify women with mobility difficulties caused by chronic physical health conditions. Across all women regardless of CPD, women reporting current pregnancy are significantly less likely to currently smoke tobacco and report certain mental health problems. Among currently pregnant women only, women with CPD are more likely to smoke cigarettes every day (12.2 %) versus 6.3 % for pregnant women without CPD (p ≤ 0.001). Among currently pregnant women, 17.7 % of women with CPD have BMIs in the non-overweight range, compared with 40.1 % of women without CPD (p ≤ 0.0001). Currently pregnant women with CPD are significantly more likely to report having any mental health problems, 66.6 % compared with 29.7 % among women without CPD (p ≤ 0.0001). For all women, currently pregnant women appear to have fewer health risks and mental health concerns than nonpregnant women. Among pregnant women, women with CPD have higher rates than other women of health risk factors that could affect maternal and infant outcomes.

The fingerprint is a commonly used biometric modality that is widely employed for authentication by law enforcement agencies and commercial applications. The designs of existing fingerprint matching methods are based on the hypothesis that the same sensor is used to capture fingerprints during enrollment and verification. Advances in fingerprint sensor technology have raised the question about the usability of current methods when different sensors are employed for enrollment and verification; this is a fingerprint sensor interoperability problem. To provide insight into this problem and assess the status of state-of-the-art matching methods to tackle this problem, we first analyze the characteristics of fingerprints captured with different sensors, which makes cross-sensor matching a challenging problem. We demonstrate the importance of fingerprint enhancement methods for cross-sensor matching. Finally, we conduct a comparative study of state-of-the-art fingerprint recognition methods and provide insight into their abilities to address this problem. We performed experiments using a public database (FingerPass) that contains nine datasets captured with different sensors. We analyzed the effects of different sensors and found that cross-sensor matching performance deteriorates when different sensors are used for enrollment and verification. In view of our analysis, we propose future research directions for this problem. PMID:29597286

Despite the existence of the universal right to a healthy environment, the right is being violated in some populations. The objective of the current study is to verify environmental discrimination associated with socioeconomic status in Korea, using synthetic air quality index and multiple indicators of socioeconomic status. The concentrations of NO₂(nitrogen dioxide), CO (carbon monoxide), SO₂(sulfur dioxide), PM10 (particulate matter with an aerodynamic diameter <10 μm), and O₃(ozone) in ambient air were integrated into a synthetic air quality index. Socioeconomic status was measured at individual level (income, education, number of household members, occupation, and National Basic Livelihood status) and area level (neighborhood index). The neighborhood index was calculated in the finest administrative unit (municipality) by performing standardization and integration of municipality-level data of the following: number of families receiving National Basic Livelihood, proportion of people engaged in an elementary occupation, population density, and number of service industries. Each study participant was assigned a neighborhood index value of the municipality in which they reside. Six regression models were generated to analyze the relationship between socioeconomic status and overall air pollution. All models were adjusted with sex, age, and smoking status. Stratification was conducted by residency (urban/rural). Moran's I was calculated to identify spatial clusters, and adjusted regression analysis was conducted to account for spatial autocorrelation. Results showed that people with higher neighborhood index, people living with smaller number of family members, and people with no education lived in municipalities with better overall air quality. The association differed by residency in some cases, and consideration of spatial autocorrelation altered the association. This study gives strength to the idea that environmental discrimination exists in some socioeconomic groups in Korea, and that residency and spatial autocorrelation must be considered in order to fully understand environmental disparities. This is the first study that provides the possible evidence of the environmental injustice in Korea using air quality index. The findings suggested that air quality index was negatively correlated with several important socioeconomic status measured at either individual or area level. The main implication of this paper, therefore, is to provide another insight to environmental policy makers to consider environmental injustice problem into community intervention for resolving the public health problems by air pollution.

Current status and perspectives of Clonorchis sinensis and clonorchiasis: epidemiology, pathogenesis, omics, prevention and control.

2016-07-06

Clonorchiasis, caused by Clonorchis sinensis (C. sinensis), is an important food-borne parasitic disease and one of the most common zoonoses. Currently, it is estimated that more than 200 million people are at risk of C. sinensis infection, and over 15 million are infected worldwide. C. sinensis infection is closely related to cholangiocarcinoma (CCA), fibrosis and other human hepatobiliary diseases; thus, clonorchiasis is a serious public health problem in endemic areas. This article reviews the current knowledge regarding the epidemiology, disease burden and treatment of clonorchiasis as well as summarizes the techniques for detecting C. sinensis infection in humans and intermediate hosts and vaccine development against clonorchiasis. Newer data regarding the pathogenesis of clonorchiasis and the genome, transcriptome and secretome of C. sinensis are collected, thus providing perspectives for future studies. These advances in research will aid the development of innovative strategies for the prevention and control of clonorchiasis.

Current Status of New Anticoagulants in the Management of Venous Thromboembolism

Venous Thromboembolism, manifested as deep venous thrombosis and pulmonary embolism, is a common problem associated with significant morbidity, mortality, and resource expenditure. Unfractionated heparin, low-molecular-weight heparin, and vitamin K antagonists are the most common treatment and prophylaxis, and have demonstrated their efficacy in a vast number of previous studies. Despite their broad use, these agents have important limitations that have led to the development of new drugs in a bid to overcome the disadvantages of the old ones without decreasing their therapeutic effect. These novel medications, some approved and others in different stages of development, include direct thrombin inhibitors like dabigatran etexilate, and direct activated factor X inhibitors like rivaroxaban. The current paper will review the characteristics, clinical trial results, and current and potential therapeutic uses of these new agents with a focus on the categories of direct thrombin inhibitors and activated factor X inhibitors.

Knowledge about alcohol consumption patterns and alcohol problems among the Belgian elderly population is scarce. The aims of this study were to explore alcohol consumption patterns and alcohol problems among the Belgian elderly population aged ≥ 65 years living at home, and to determine their association with socio-demographic characteristics, health status and socio-economic status. In this cross-sectional study based on a representative sample of 4825 non-institutionalized Belgian elderly people (≥ 65 years) in the Belgian Health Interview Surveys 2001 and 2004, alcohol consumption patterns and alcohol problems were estimated according to age, gender, survey year, living situation, frequency of social contacts, smoking status, and socio-economic status. In all, 50.4% of the sample were non- or occasional drinkers, 29.1% were moderate drinkers, 10.4% at-risk drinkers, 4.6% heavy drinkers and 5.5% problematic drinkers. In total, 20.5% of the Belgian elderly population drank in excess of the National Institute on Alcohol Abuse and Alcoholism guidelines, and 4.7% had an alcohol problem according to the CAGE. In addition, 81.3% of the elderly people who consume alcohol used prescribed medications in the past 2 weeks. After adjustment for risk factors we found that, compared with moderate drinking, unhealthy drinking was significantly associated with age, gender, frequency of social contacts, health status and socio-economic status. Belgian health policy should be aware of the high level of at-risk drinkers in the elderly population and the underdetection and misdiagnosis of alcohol problems in this age group. An increased attention in public health initiatives among the Belgian elderly population is needed.

This study aimed to compare the effectiveness of a 6-week combined exercise program with and without connective tissue massage (CTM) on pain, fatigue, sleep problem, health status, and quality of life in patients with fibromyalgia syndrome (FMS). Patients were randomly allocated into Exercise (n = 20) and Exercise + CTM (n = 20) groups. The exercise program with and without CTM was carried out 2 days a week for 6 weeks. Pain, fatigue, sleep problem with Visual Analog Scales, health status with Fibromyalgia Impact Questionnaire (FIQ), and quality of life with Short Form-36 were evaluated. After the program, pain, fatigue and sleep problem reduced, health status (except of the scores of FIQ-1 and FIQ-10), physical functioning, role limitations due to physical health, bodily pain, role limitations due to emotional health, vitality, and general health perceptions parameters related to quality of life improved in the Exercise group, (P < 0.05). In the Exercise + CTM group, pain, fatigue and sleep problem decreased, health status and quality of life improved (P < 0.05). Pain, fatigue, sleep problem, and role limitations due to physical health improved in the Exercise + CTM group in comparison to the Exercise group (P < 0.05). The study suggested that exercises with and without CTM might be effective for decreasing pain, fatigue and sleep problem whereas increasing health status and quality of life in patients with FMS. However, exercises with CTM might be superior in improving pain, fatigue, sleep problem, and role limitations due to physical health compared to exercise alone.

This study attempted to give a medical and social prognosis for patients with perceived "electrical sensitivity". In 1980-1998, 350 patients with electrical sensitivity were registered at the University Hospital of Northern Sweden in Umeå, Sweden. Those with hypersensitivity to electricity had multiple symptoms evoked by exposure to different electric environments. Those with skin symptoms related to the use of visual display terminals (VDT) predominantly had facial skin symptoms evoked by a VDT, television screens, or fluorescent light tubes. A questionnaire on civil status, current health status, care, treatment and other measures taken, consequences of the problem, eliciting factors, and current employment was sent to all the patients. The response rate was 73%. Of the 50 respondents with hypersensitivity to electricity, 38% were men and 62% were women. Of the 200 patients with skin symptoms related to VDT use, 21.5% were men and 78.5% women. More women than men had turned to caregivers, including complementary therapies. A larger proportion of patients with hypersensitivity to electricity (38%) than those with skin symptoms related to VDT use (17%) was no longer gainfully employed. Both groups reported a higher symptom frequency than that reported by the the general population. Over time, the medical prognosis improved in the latter group but not in the former. Patients with hypersensitivity to electricity, particularly women, have extensive medical problems and a considerable number of them stop working. Many patients with skin symptoms related to VDT use have a favorable prognosis. Both groups need early and consistent management.

Current status of Kampo medicine curricula in all Japanese medical schools

2012-01-01

Background There have been a few but not precise surveys of the current status of traditional Japanese Kampo education at medical schools in Japan. Our aim was to identify problems and suggest solutions for a standardized Kampo educational model for all medical schools throughout Japan. Methods We surveyed all 80 medical schools in Japan regarding eight items related to teaching or studying Kampo medicine: (1) the number of class meetings, target school year(s), and type of classes; (2) presence or absence of full-time instructors; (3) curricula contents; (4) textbooks in use; (5) desire for standardized textbooks; (6) faculty development programmes; (7) course contents; and (8) problems to be solved to promote Kampo education. We conducted descriptive analyses without statistics. Results Eighty questionnaires were collected (100%). (1) There were 0 to 25 Kampo class meetings during the 6 years of medical school. At least one Kampo class was conducted at 98% of the schools, ≥4 at 84%, ≥8 at 44%, and ≥16 at 5%. Distribution of classes was 19% and 57% for third- and fourth-year students, respectively. (2) Only 29% of schools employed full-time Kampo medicine instructors. (3) Medicine was taught on the basis of traditional Japanese Kampo medicine by 81% of the schools, Chinese medicine by 19%, and Western medicine by 20%. (4) Textbooks were used by 24%. (5) Seventy-four percent considered using standardized textbooks. (6) Thirty-three percent provided faculty development programmes. (7) Regarding course contents, “characteristics” was selected by 94%, “basic concepts” by 84%, and evidence-based medicine by 64%. (8) Among the problems to be solved promptly, curriculum standardization was selected by 63%, preparation of simple textbooks by 51%, and fostering instructors responsible for Kampo education by 65%. Conclusions Japanese medical schools only offer students a short time to study Kampo medicine, and the impetus to include Kampo medicine in their curricula varies among schools. Future Kampo education at medical schools requires solving several problems, including curriculum standardization. PMID:23122050

We investigated whether abused and neglected children are at risk for negative physical health outcomes in adulthood. Using a prospective cohort design, we matched children (aged 0-11 years) with documented cases of physical and sexual abuse and neglect from a US Midwestern county during 1967 through 1971 with nonmaltreated children. Both groups completed a medical status examination (measured health outcomes and blood tests) and interview during 2003 through 2005 (mean age=41.2 years). After adjusting for age, gender, and race, child maltreatment predicted above normal hemoglobin, lower albumin levels, poor peak airflow, and vision problems in adulthood. Physical abuse predicted malnutrition, albumin, blood urea nitrogen, and hemoglobin A1C. Neglect predicted hemoglobin A1C, albumin, poor peak airflow, and oral health and vision problems, Sexual abuse predicted hepatitis C and oral health problems. Additional controls for childhood socioeconomic status, adult socioeconomic status, unhealthy behaviors, smoking, and mental health problems play varying roles in attenuating or intensifying these relationships. Child abuse and neglect affect long-term health status-increasing risk for diabetes, lung disease, malnutrition, and vision problems-and support the need for early health care prevention.

Intestinal helminth infections of livestock and humans are predominantly controlled by treatment with three classes of synthetic drugs, but some livestock nematodes have now developed resistance to all three classes and there are signs that human hookworms are becoming less responsive to the two classes (benzimidazoles and the nicotinic acetylcholine agonists) that are licensed for treatment of humans. New anthelmintics are urgently needed, and whilst development of new synthetic drugs is ongoing, it is slow and there are no signs yet that novel compounds operating through different modes of action, will be available on the market in the current decade. The development of naturally-occurring compounds as medicines for human use and for treatment of animals is fraught with problems. In this paper we review the current status of cysteine proteinases from fruits and protective plant latices as novel anthelmintics, we consider some of the problems inherent in taking laboratory findings and those derived from folk-medicine to the market and we suggest that there is a wealth of new compounds still to be discovered that could be harvested to benefit humans and livestock.

A workshop on atmospheric processes over complex terrain, sponsored by the American Meteorological Society, was convened in Park City, Utah from 24 vto 28 October 1988. The overall objective of the workshop was one of interaction and synthesis--interaction among atmospheric scientists carrying out research on a variety of orographic flow problems, and a synthesis of their results and points of view into an assessment of the current status of topical research problems. The final day of the workshop was devoted to an open discussion on the research directions that could be anticipated in the next decade because of new and planned instrumentation and observational networks, the recent emphasis on development of mesoscale numerical models, and continual theoretical investigations of thermally forced flows, orographic waves, and stratified turbulence. This monograph represents an outgrowth of the Park City Workshop. The authors have contributed chapters based on their lecture material. Workshop discussions indicated interest in both the remote sensing and predictability of orographic flows. These chapters were solicited following the workshop in order to provide a more balanced view of current progress and future directions in research on atmospheric processes over complex terrain.

Research indicates that the relationship between socioeconomic status (SES) and delinquency is not as strong as suggested by the leading crime theories. This article argues that such theories do not predict that SES in and of itself causes delinquency but rather that the economic problems associated with SES cause delinquency. Such problems…

Purpose This study examined the association between early initiation of problem behaviors (alcohol drinking, cigarette smoking, and sexual intercourse) and suicidal behaviors (suicidal ideation and suicide attempts), and explored the effect of concurrent participation in these problem behaviors on suicidal behaviors among Korean adolescent males and females. Materials and Methods Data were obtained from the 2006 Korean Youth Risk Behavior Survey, a nationally representative sample of middle and high school students (32,417 males and 31,467 females) in grades seven through twelve. Bivariate and multivariate logistic analyses were conducted. Several important covariates, such as age, family living structure, household economic status, academic performance, current alcohol drinking, current cigarette smoking, current butane gas or glue sniffing, perceived body weight, unhealthy weight control behaviors, subjective sleep evaluation, and depressed mood were included in the analyses. Results Both male and female preteen initiators of each problem behavior were at greater risk for suicidal behaviors than non-initiators, even after controlling for covariates. More numerous concurrent problematic behaviors were correlated with greater likelihood of seriously considering or attempting suicide among both males and females. This pattern was more clearly observed in preteen than in teen initiators although the former and latter were engaged in the same frequency of problem behavior. Conclusion Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors. PMID:20046509

While the current knowledge base on the mental health effects of displacement is mainly limited to refugees residing in industrialised countries, this paper examines the impact of war-induced displacement and related risk factors on the mental health of Eastern Congolese adolescents, and compares currently internally displaced adolescents to returnees and non-displaced peers. Data were collected from a community sample of 819 adolescents aged 13 to 21 years, attending one of 10 selected schools across the Ituri district in the Democratic Republic of Congo. Respondents completed culturally adapted self-report measures of posttraumatic stress symptoms (using the Impact of Event Scale - Revised) and internalising and externalising behaviour problems (by means of the Hopkins Symptoms Checklist - 37 for Adolescents). Associated factors studied were age, sex, parental death, exposure to war-related violence and daily stressors. Internally displaced persons (IDPs) reported highest mean scores for the IES-R and the HSCL-37A internalising scale, followed by returnees, while non-displaced adolescents scored significantly lower. However, ANCOVA tests showed that posttraumatic stress and internalising symptoms were mainly associated with traumatic exposure and daily stressors and not with displacement status. Externalising problem scores were associated with traumatic exposure, daily stressors and displacement. Remarkably, death of father was associated with fewer externalising problems. Sex was differently associated with internalising and externalising problems through traumatic and daily stressors. As IDPs are highly exposed to violence and daily stressors, they report most psychological distress, when compared to returnees and non-displaced peers. The distinct mental health outcomes for returned youngsters illustrate how enhancing current socio-economic living conditions of war-affected adolescents could stimulate resilient outcomes, despite former trauma or displacement.

Research on families of individuals with autism has tended to focus on child-driven effects utilizing models of stress and coping. The current study used a family-systems perspective to examine whether family-level adaptability promoted beneficial outcomes for mothers and their adolescents with autism over time. Participants were 149 families of children diagnosed with autism who were between the ages of 10 and 22 years during the three-year period examined. Mothers reported on family adaptability, the mother-child relationship, their own depressive symptoms, and the behavior problems of their children at Wave 1, and these factors were used to predict maternal depression and child behavior problems three years later. Family-level adaptability predicted change in both maternal depression and child behavior problems over the study period, above and beyond the contribution of the dyadic mother-child relationship. These associations did not appear to depend upon the intellectual disability status of the individual with autism. Implications for autism, parent mental health, family systems theory, and for intervention with this population are discussed. PMID:21668120

Background : Despite the well-established link between exposure to violence and mental health problems, less is known about this association among college students. The current study aimed to investigate the association between history of exposure to violence and mental health of American college students. Methods : Healthy Mind Study (HMS, 2016⁻2017) is a national online survey of 41,898 adult college students. The independent variable was lifetime history of exposure to violence (psychological, physical, and sexual). The dependent variables were anxiety, depression, and suicidality. Race, age, gender, sexual orientation, parental education, financial stress, transfer status, enrollment status, and graduate status were covariates. Linear and logistic regression models were used for data analysis. Results : History of exposure to violence was associated with all three aspects of poor mental health, namely general anxiety, depression, and suicidality. These associations were independent of covariates and type of abuse. Conclusions : There is a need to address various mental health needs of college students who have experienced various forms of violence. College students who screen positive for history of violence exposure should be evaluated for anxiety, depression, and suicidal behaviors.

Objective Examine health of preschoolers by BMI status. Methods A cross-sectional analysis of children 3 to 5 years old in the 1999–2008 National Health and Nutrition Examination Survey was carried out. The measured age- and sex-specific BMI percentiles were used to categorize children as very obese, obese, overweight, or healthy weight. The authors used logistic regression to examine the effect of weight status on 17 available measures of current child health potentially related to obesity. Results Except for very obese children, weight status had minimal effect on most measures of health for preschool-aged children (n = 2792). Parents of very obese children reported poorer general health and more activity limitations for their children. Additionally, very obese girls had more frequent/severe headaches, and overweight/obese boys had more asthma diagnoses. Conclusions Only severe obesity appears consistently related to immediate health problems in preschool-aged children. Parental perception that very obese children have worse health and more activity limitations may lead to decreases in physical activity, which would perpetuate obesity. PMID:20308197

Falls and fall related injuries become an emerging health problem among older adults. As a result a review of the recent evidences is needed to design a prevention strategy. The aim of this review was to determine the effect of square stepping exercise (SSE) for fall down injury among older adults compared with walking training or other exercises. An electronic database search for relevant randomized control trials published in English from 2005 to 2016 was conducted. Articles with outcome measures of functional reach, perceived health status, fear of fall were included. Quality of the included articles was rated using Physiotherapy Evidence Database (PEDro) scale and the pooled effect of SSE was obtained by Review Manager (RevMan5) software. Significant effect of SSE was detected over walking or no treatment to improve balance as well to prevent fear of fall and improve perceived health status. The results of this systematic review proposed that SSE significantly better than walking or no treatment to prevent fall, prevent fear of fall and improve perceived health status.

The common-sense construction of Buddhism is that of a general power for good; the less positive aspects of Buddhism's power, especially when reinforced by folklore and ancient superstition, is infrequently recognised. In this article we make explicit Buddhism's less positive power, particularly as it relates to the status of women and, by implication, its role in the human immunodeficiency (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in Thailand. The Buddhist, folklore, and superstitious bases of Thai misogyny are explored, together with its expression in the differential gender roles of women and men. In addition, the attitudes of both women and men to commercial sex workers (CSWs) and condom use is discussed. The implications of these attitudinal analyses to the epidemiology of HIV/AIDS in Thailand is outlined. We argue that the current spread of HIV/AIDS in Thailand is primarily a function of the inferior status of women, which, in turn, is a function of Buddhism and Thai cultural beliefs. In light of this, some realistic strategies to address the problem also are discussed.

The effectiveness of learning with concept mapping on the science problem-solving of sixth-grade children

NASA Astrophysics Data System (ADS)

Jolly, Anju B.

The purpose of this study was to analyze the relationship of concept mapping to science problem solving in sixth grade elementary school children. The study proposes to determine whether the students' ability to perform higher cognitive processes was a predictor of students' performance in solving problems in science and whether gender and socioeconomic status are related to performance in solving problems. Two groups participated in the study. Both groups were given a pre-test of higher cognitive ability--the Ross Test of Higher Cognitive Ability. One group received instruction on a science unit of study in concept mapping format and the other group received instruction in traditional format. The instruction lasted approximately 4 weeks. Both groups were given a problem-solving post-test. A comparison of post-test means was done using Analysis of Covariance (ANCOVA) as the statistical procedure with scores on the test of higher cognitive ability as the covariate. Also, Multiple Regression was performed to analyze the influence of participants' gender and socioeconomic status on their performance in solving problems. Results from the analysis of covariance showed that the group receiving instruction in the concept mapping format performed significantly better than the group receiving instruction in traditional format. Also the Ross Test of Higher Cognitive Processes emerged to be a predictor of performance on problem solving. There was no significant difference in the analysis of the performance of males and females. No pattern emerged regarding the influence of socioeconomic status on problem solving performance. In conclusion, the study showed that concept mapping improved problem solving in the classroom, and that gender and socioeconomic status are not predictors of student success in problem solving.

Chalcopyrite is the primary copper mineral used for production of copper metal. Today, as a result of rapid industrialization, there has been enormous demand to profitably process the low grade chalcopyrite and "dirty" concentrates through bioleaching. In the current scenario, heap bioleaching is the most advanced and preferred eco-friendly technology for processing of low grade, uneconomic/difficult-to-enrich ores for copper extraction. This paper reviews the current status of chalcopyrite bioleaching. Advanced information with the attempts made for understanding the diversity of bioleaching microorganisms; role of OMICs based research for future applications to industrial sectors and chemical/microbial aspects of chalcopyrite bioleaching is discussed. Additionally, the current progress made to overcome the problems of passivation as seen in chalcopyrite bioleaching systems have been conversed. Furthermore, advances in the designing of heap bioleaching plant along with microbial and environmental factors of importance have been reviewed with conclusions into the future prospects of chalcopyrite bioleaching.

Rethinking status dystonicus.

PubMed

Ruiz-Lopez, Marta; Fasano, Alfonso

2017-12-01

Status dystonicus is a movement disorder emergency that has been a source of controversy in terms of terminology, phenomenology, and management since it was first described in 1982. Here we argue that the current use of the term status dystonicus falls well short of the precision needed for either clinical or academic use. We performed a critical review on this topic, describing possible pathophysiological mechanisms and areas of uncertainties. This review also addresses the problems derived by the extreme clinical heterogeneity of this condition, as the lack of an objective criterion useful for the definition, or the fact that status dystonicus may present not only in the context of a known dystonic syndrome. We propose a new possible definition that includes not only dystonia but also other hyperkinetic movements in the wide range of movement disorders that can be seen during an episode. The new definition keeps the term status dystonicus and highlights the fact that this is a medical emergency based on the impairment of bulbar and/or respiratory function requiring hospital admission as the principal feature. Furthermore, the new definition should not consider as necessary unspecific features as patient's condition at baseline, the distribution of dystonia, occurrence of systemic symptoms such as fever or laboratory findings. We hope that this proposal will stimulate the debate on this subject among our peers, further developing a clinical and pathophysiological understanding of status dystonicus. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

A Description of Suicides in the Army National Guard During 2007-2014 and Associated Risk Factors.

Suicide, due to its increased occurrence in recent years, has been a chief concern of the U.S. military. While there have been many published studies on the topic, conspicuously absent are studies that have included reserve military personnel. To fill this gap, this study reports descriptive statistics of personnel information and events surrounding 706 Army National Guard suicides that had occurred from 2007 through 2014. Comparative personnel information for random samples of nonsuicides for similar years (8 years, 1,000 cases per year) allowed examining factors associated most with suicide. Findings were very similar to those observed in the active duty Army and civilian populations. Primary risk factors for suicide were as follows: age (young), gender (male), and race/ethnicity (White). Most suicides occurred in nonmilitary status (86%) involving personal firearms (72%). Most frequent events surrounding the suicide were as follows: poor military performance (36% of all suicides), parent-family relationship problems (28%), substance abuse (27%), past behavioral health problem (20%), current behavioral health problems (10%), income problems (22%), and full-time employment problems (18%). Implications of findings for suicide prevention are discussed. © 2016 The American Association of Suicidology.

Korea has the fastest aging population and least fertile population of all Organization Economic Cooperation and Development countries, and it is undertaking significant preparations for an aging society. So, we want to review the present status of Elderly workers' occupational disorders and preparations, which is performed by governmental, social parties. We examine the current status of Korea's aging work force, focusing on occupational disorders (injuries and diseases), and retirements, and the associated health effects. Despite the efforts and concern about Korea's aging society since the issue was first identified, Korea's limited experience in operating a national public pension system, and a mature social security system shows that the needs of Korea's aging society cannot be fully satisfied. This problem has already resulted in increasing labor employment rates and delays in retirement from the labor market. We suggest a policy for elderly workers considering various determinants that can lead to successful employment, retirement, and health promotion for the aging work force.

The Emerging Infections Program (EIP), a collaboration between (currently) 10 state health departments, their academic center partners, and the Centers for Disease Control and Prevention, was established in 1995. The EIP performs active, population-based surveillance for important infectious diseases, addresses new problems as they arise, emphasizes projects that lead to prevention, and develops and evaluates public health practices. The EIP has increasingly addressed the health equity challenges posed by Healthy People 2020. These challenges include objectives to increase the proportion of Healthy People–specified conditions for which national data are available by race/ethnicity and socioeconomic status as a step toward first recognizing and subsequently eliminating health inequities. EIP has made substantial progress in moving from an initial focus on monitoring social determinants exclusively through collecting and analyzing data by race/ethnicity to identifying and piloting ways to conduct population-based surveillance by using area-based socioeconomic status measures.

Objective To examine demographic differences in parenting behaviors and adjustment in youth with type 1 diabetes. Methods Adolescents’ psychosocial adjustment was assessed via self-reports and parent reports, and clinical data were obtained from adolescents’ medical records. Mother–adolescent dyads (N = 93) engaged in a videotaped discussion task, which was coded for observed parenting behaviors. Results Single and non-White mothers exhibited significantly more overinvolved and less collaborative parenting behaviors. Higher levels of overinvolved parenting and lower levels of collaborative parenting were associated with poorer adolescent adjustment (i.e., higher levels of externalizing problems). Observed parenting was not significantly associated with glycemic control. There was an indirect effect of marital status and race/ethnicity on externalizing behaviors through parenting. Conclusions The current study highlights parenting as a potential target for interventions, especially in single and minority mothers, to improve adjustment in this population.

Numerous studies have documented that lower socioeconomic status (SES) is associated with increased mental health problems in children. One proposed pathway for this association has been differential exposure to accumulated risk factors in children of lower SES. The aim of the current study was to investigate the socioeconomic distribution of exposure to negative life events and family stress and to examine the direct and interactive association between lower SES and exposure to life events and family stress in relation with mental health problems. Using cross-sectional data from the second wave of the Bergen Child Study (conducted in 2006), the current study investigated the association between lower SES and exposure to negative life events, family life stressors, and mental health problems in a sample of 2043 Norwegian 11-13 years and their parents. Information about mental health was self-reported by the children using the Strengths and Difficulties Questionnaire, whereas information about SES and exposure to negative life events and family stressors were provided by their parents. The findings showed that lower SES was associated with more symptoms of emotional-, conduct-, hyperactivity/inattention-, and peer problems and that exposure to life events and family stress explained some of this association (10-29% of the total effects). Low SES and higher prevalence of negative life events and family stressors were associated with more symptoms of mental health problems. Overall, the effect sizes were smaller than previous investigations (f 2 s = 0.015-0.031), perhaps suggesting a buffering effect of the social safety net in place in Norway.

We sought to identify possible subgroups of elders that varied in depressive symptomatology and to examine symptom patterns and health status differences between subgroups. The Cache County memory study is a population-based epidemiological study of dementia with 5092 participants. Depressive symptoms were measured with a modified version of the diagnostic interview schedule-depression. There were 400 nondemented participants who endorsed currently (i.e., in the past 2 weeks) experiencing at least one of the three "gateway" depressive symptoms and then completed a full depression interview. Responses to all nine current depressive symptoms were modeled using the latent class analysis. Three depression subgroups were identified: a significantly depressed subgroup (62%), with the remainder split evenly between a subgroup with low probability of all symptoms (21%), and a subgroup with primarily psychomotor changes, sleep symptoms, and fatigue (17%). Latent class analysis derived subgroups of depressive symptoms and Diagnostic and statistical manual of mental disorders, fourth edition depression diagnostic group were nonredundant. Age, gender, education, marital status, early or late onset, number of episodes, current episode duration, and functional status were not significant predictors of depression subgroup. The first subgroup was more likely to be recently bereaved and had less physical health problems, whereas the third subgroup were less likely to be using antidepressants compared with the second subgroup. There are distinct subgroups of depressed elders, which are not redundant with the Diagnostic and statistical manual of mental disorders, fourth edition classification scheme, offering an alternative diagnostic approach to clinicians and researchers. Future work will examine whether these depressive symptom profiles are predictive of incident dementia and earlier mortality. Copyright © 2011 John Wiley & Sons, Ltd.

2018-01-01

Statement of the Problem: Dental caries, the most common infectious disease, can lead to several consequences, including inflammation and bleeding of the gum, abscess formation, tooth loss, and subsequently loss of available space in the arch. Purpose: This study was designed to determine dental caries status of Shiraz preschool children and its related factors. Materials and Method: This cross-sectional study was conducted on the children registered in Shiraz kindergartens in 2014. The study recruited 453 children by randomized cluster sampling. We evaluated the children’s demographic and oral hygiene factors, and their dental caries status using decayed, missed, and filled tooth (dmft) index and prevalence of the children with untreated dental caries. Relationship between the children’s characteristics and their dental caries status was evaluated. Results: Only 119 children (30.1%) were caries-free. The children’s mean dmft index was 3.88(±3.9). After controlling the effect of confounding factors, the children’s dental caries status was significantly associated with variables indicating their socioeconomic status such as fathers’ job, mothers’ education, and number of children in the family. Furthermore, there was a significant association between the children’s dental caries status and their oral hygiene habits such as frequency of tooth brushing. Conclusion: The dental caries status of the studied preschool children was not desirable which could be indicative of the inadequacy of the current preventive programs. To improve this issue, interventional preventive programs such as tooth brushing are recommended. The programs are more necessary for the children of low socioeconomic families and those with poor oral hygiene habits. PMID:29854883

Over the past few decades, the field of food security has witnessed numerous problems and incidents that have garnered public attention. Given this serious situation, the food traceability system (FTS) has become part of the expanding food safety continuum to reduce the risk of food safety problems. This article reviews a great deal of the related literature and results from previous studies of FTS to corroborate this contention. This article describes the development and benefits of FTS in developed countries like the United States of America (USA), Japan, and some European countries. Problems with existing FTS in China are noted, including a lack of a complete database, inadequate laws and regulations, and lagging technological research into FTS. This article puts forward several suggestions for the future, including improvement of information websites, clarification of regulatory responsibilities, and promotion of technological research.

2017-11-01

In recent years, pollution accidents caused by gas station leakage has occurred worldwide which can be persistent in groundwater. Numerous studies have demonstrated that the contaminated groundwater is threatening the ecological environment and human health. In this article, current status and sources of groundwater pollution by gas station are analyzed, and experience of how to prevent groundwater pollution from gas stations are summarized. It is demonstrated that installation of secondary containment measures for the oil storage of the oil tank system, such as installation of double-layer oil tanks or construction of impermeable ponds, is a preferable method to prevent gas stations from groundwater pollution. Regarding to the problems of groundwater pollution caused by gas station, it is proposed that it is urgent to investigate the leakage status of gas station. Relevant precise implementation regulations shall be issued and carried out, and supervision management of gas stations would need to be strengthened. Then single-layer steel oil tanks shall be replaced by double-layer tanks, and the impermeable ponds should be constructed according to the risk ranking. From the control methodology, the groundwater environment monitoring systems, supervision level, laws and regulations as well as pollution remediation should also be carried out and strengthened.

The purpose of this study was to consider appropriate application of liquid and re-biopsy through analysis of current status in practice. We performed a retrospective analysis of 22 patients with epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer who exhibited 1st/2nd generation EGFR-tyrosine kinase inhibitors resistance. The cobas® method was used to detect T790M with re-biopsy and the mutation-biased PCR and quenched probe method was used with liquid biopsy. T790M detection rate was 52% with re-biopsy and 58% with liquid biopsy. The concordance between tissue and plasma was 58%. One patient who was T790M-positive with liquid biopsy showed heterogeneity among metastatic lesions in terms of osimertinib efficacy, as revealed by T790M detection with re-biopsy. Liquid biopsy reflects the whole body, whereas re-biopsy is useful for spatial diagnosis. Considering these characteristics, a combination of liquid and re-biopsy contribute to enhanced treatment.

VehiHealth: An Emergency Routing Protocol for Vehicular Ad Hoc Network to Support Healthcare System.

PubMed

Bhoi, S K; Khilar, P M

2016-03-01

Survival of a patient depends on effective data communication in healthcare system. In this paper, an emergency routing protocol for Vehicular Ad hoc Network (VANET) is proposed to quickly forward the current patient status information from the ambulance to the hospital to provide pre-medical treatment. As the ambulance takes time to reach the hospital, ambulance doctor can provide sudden treatment to the patient in emergency by sending patient status information to the hospital through the vehicles using vehicular communication. Secondly, the experienced doctors respond to the information by quickly sending a treatment information to the ambulance. In this protocol, data is forwarded through that path which has less link breakage problem between the vehicles. This is done by calculating an intersection value I v a l u e for the neighboring intersections by using the current traffic information. Then the data is forwarded through that intersection which has minimum I v a l u e . Simulation results show VehiHealth performs better than P-GEDIR, GyTAR, A-STAR and GSR routing protocols in terms of average end-to-end delay, number of link breakage, path length, and average response time.

2016-03-01

Thanks to the progress of surgical theory and skills, as well as the application of modern medical devices in general surgery, both the occurrence of perioperative complications and mortality of gastrointestinal surgery have significantly reduced recently. However, it is still far from optimal in terms of the perioperative venous thromboembolism (VTE) management in gastrointestinal cancer, and what is responsible for that? This paper aims at finding out the reasons contributing to the current status, giving suggestions for how to make improvement at both disease level and hospital management level. At the same time, while paying attention for the prophylaxis of VTE, there have been more and more patients receiving antithrombotic treatment require elective or emergent surgery in clinical practice, due to aging and increased incidence of cardiovascular disease year by year. How to balance the bleeding and thrombosis risk for these patients during perioperative periods is also a question we are going to discuss. In conclusion, as to the issue of the management of perioperative thrombosis, there will be a long way for Chinese doctors to go. Our peers should pay more attention to this problem and take more efforts, so that the thrombotic complications in surgical patients can be reduced.

Hydrofluoric acid (HF), a dangerous inorganic acid, can cause severe corrosive effects and systemic toxicity. HF enters the human body via where it contacts, such as skin and mucosa, alimentary and respiratory tracts, and ocular surfaces. In the recent years, the incidence of HF burn has tended to increase over time. The injury mechanism of HF is associated primarily with the massive absorption of HF and the release of hydrogen ions. Correct diagnosis and timely treatment are especially important for HF burns. The critical procedure to treat HF burn is to prevent on-going HF absorption, and block the progressive destruction caused by fluoride ions. Due to the distinct characteristics of HF burns, the topical treatment, as well as systemic support, has been emphasised. Whereas, management of patients with HF burns remains a great challenge in some situations. To date, there has been no widely accepted protocol for the rescue of HF burns, partly due to the diversity of HF burns. This paper overviews the current status and problems of treatment strategies for HF burns, for the purpose of promoting the future researches and improvement. Copyright © 2014 Elsevier Ltd and ISBI.

1983-01-01

The history, current status, and future plans of the Spacelab program are reviewed, with a focus on the cooperative relationship between ESA and NASA. The initial decision to undertake the program and the three agreements signed to begin its implementation are examined, and the division of responsibilities and financial contributions is discussed insofar as it affected the management structure. Consideration is given to the major facilities, the 50-mission operational cycle, communications, the currently scheduled activities (through 1985), the prospective later uses, and the ten dedicated discipline laboratories. The importance of continuous mutual support during the planning and development phases is stressed. The program so far is considered a success, in terms of the goals set by the participants and in terms of the resolution of the problems inherent in international technological endeavors.

1991-01-01

The preparation of high-temperature superconducting ceramics in bulk form is a major challenge in materials science. The current status of both partial melting and melt quenching techniques, with or without an intermediate powder processing stage, is described in detail, and the problems associated with each of the methods are discussed. Results of studies performed on melt-processed materials are reported and discussed. The discussion places emphasis on magnetization and on other physical properties associated with it, such as critical current density, levitation force, and flux creep. The nature of structural features which give rise to flux pinning, including both small and large defects, is discussed with reference to theoretical considerations. The rates of flux creep and the factors involved in attempting to retard the decay of the magnetization are surveyed.

Many forms of technology, both "high" and "low," can help individuals with learning disabilities capitalize on their strengths and bypass, or compensate for, their disabilities. This article surveys the current status of assistive technology for this population and reflects on future promises and potential problems. In addition, a model is presented for conceptualizing assistive technology in terms of the types of barriers it helps persons with disabilities to surmount. Several current technologies are described and the research supporting their effectiveness reviewed: word processing, computer-based instruction in reading and other academic areas, interactive videodisc interventions for math, and technologies for daily life. In conclusion, three themes related to the future success of assistive technology applications are discussed: equity of access to technology; ease of technology, use; and emergent technologies, such as virtual reality.

2012-01-01

The purpose of this study was to identify how remitters and relapsers view their everyday problem solving strategies. A total of 128 male alcohol dependent male inpatients who were hospitalized at the Ankara University Psychiatry Clinic, Alcohol and Substance Abuse Treatment Unit were recruited for the study. Subjects demographic status and alcohol use histories were assessed by a self-report questionnaire. Also, patients were evaluated with The Coopersmith Self-esteem Inventory (CSI), The Spielberger State-Trait Anxiety Scale (STAI-I-II), and The Problem Solving Inventory (PSI). Patients were followed for six months with monthly intervals after hospital discharge. Drinking status was assessed in terms of abstinence and relapse. Data were assessed with Student t-test, and univariate and multivariate analyses. In the logistic regression analysis, age, marital status, employment status and PSI subscores were taken as the independent variables and drinking state at the end of six months as the dependent variable. There were significant differences in reflective and avoidant styles, and monitoring style of problem solving between abstainers and relapses. It was found that subjects who perceived their problem solving style as less avoidant and less reflective were at greater risk to relapse. The findings demonstrated that active engagement in problem solving like utilizing avoidant and reflective styles of problem solving enhances abstinence. In treatment, expanding the behavior repertoire and increasing the variety of ways of problem solving ways that can be utilized in daily life should be one of the major goals of the treatment program.

Although renal transplantation has proved a successful treatment for the patients with end-stage renal failure, the therapy is hampered by the problem of serious shortage of donor organs. Regenerative medicine using stem cells, including cell transplantation therapy, needs to be developed to solve the problem. We previously identified the multipotent progenitor cells in the embryonic mouse kidney that can give rise to several kinds of epithelial cells found in adult kidney, such as glomerular podocytes and renal tubular epithelia. Establishing the method to generate the progenitors from human pluripotent stem cells that have the capacity to indefinitely proliferate in vitromore » is required for the development of kidney regeneration strategy. We review the current status of the research on the differentiation of pluripotent stem cells into renal lineages and describe cues to promote this research field.« less

Health inputs and cumulative health deficits among the older Chinese.

Gu, Danan; Sautter, Jessica; Huang, Cheng; Zeng, Yi

2011-03-01

Using a health economics framework, we examined how both individual level investments at different life stages and current community-level environmental factors affect individual health stock and flows at old ages. We used a nationwide dataset from the 2002 and 2005 waves of the Chinese Longitudinal Healthy Longevity Survey, which included more than 15,000 adults aged 65 and older from 22 provinces in mainland China. We measured health stock with a cumulative health deficit index, a measure developed in geriatrics and gerontology that reflects deficits, illnesses, and functional impairment in numerous domains of health. The cumulative health deficit index has not been used in health economics before, but is a significant contribution because it captures the health stock concept very well and overcomes the problems of inconsistency resulting from the use of different measures of health stock in research. Our results show that several proxy measures for individual health investments in both childhood (nutritional status and parental survival status) and adulthood (family financial condition and access to healthcare) yielded positive returns to health stock measured by the cumulative health deficit index. Investments in social connections and healthy behaviors (religious involvement, alcohol use, and exercise) also produced positive returns in health stock. Current community-level factors such as air quality and labor force participation rate were significantly associated with levels of health deficits in old age as well. Yet, most of these individual investment and community environment variables did not significantly affect short-term health flows (improvement or deterioration in health status over three years). Our findings have important implications for developing preventive health programs in the context of population aging by focusing on policy-relevant predictors and a comprehensive indicator of health status in later life.

Modern cities have been trying to meet their needs for space by using not only surface structures but also by considering subsurface space use. It is also anticipated that without planning of underground spaces for supporting surface city life in the years and generations to come, there will be serious and unavoidable problems with growing populations. The current Turkish cadastral system, including land right registrations, has been trying to meet users' needs in all aspects since 1924. Today Turkey's national cadastre services are carried out by the General Directorate of Land Titles and Cadastre (TKGM). The Cadastre Law, Number 3402, was approved in 1985 to eliminate problems by gathering all existing cadastral regulations under one law and also to produce 3D cadastral bases to include underground spaces and determine their legal status in Turkey. Although the mandate for 3D cadastre works is described and explained by the laws, until now the bases have been created in 2D and the reality is that legal gaps and deficiencies presently exist in them. In this study, the usage of underground spaces for the current cadastral system in Turkey was briefly evaluated, the concept of 3D cadastral data is examined and the need for using subsurface and 3D cadastre in addition to the traditional 2D register system, related problems and registration are mentioned with specific examples, but without focusing on a specific model.

2014-01-01

This study explored the role of spiritual factors and social support on the health status of 246 older Korean adult immigrants age 65 years or older. Ordinary least squares regression results revealed that private religious practice, spiritual coping, and social support were significantly associated with improved health status. However, stressors such as the lack of English proficiency and transportation, longer residency in the United States, and financial problems were significantly associated with lower health status. Social workers need to consider providing appropriate spiritual interventions and social support programs for older Korean adult immigrants so that they may better handle their stressors and health problems.

Implications of life-history strategies for obesity

PubMed Central

Maner, Jon K.; Dittmann, Andrea; Meltzer, Andrea L.; McNulty, James K.

2017-01-01

The association between low socioeconomic status (SES) and obesity is well documented. In the current research, a life history theory (LHT) framework provided an explanation for this association. Derived from evolutionary behavioral science, LHT emphasizes how variability in exposure to unpredictability during childhood gives rise to individual differences in a range of social psychological processes across the life course. Consistent with previous LHT research, the current findings suggest that exposure to unpredictability during childhood (a characteristic common to low SES environments) is associated with the adoption of a fast life-history strategy, one marked by impulsivity and a focus on short-term goals. We demonstrate that a fast life-history strategy, in turn, was associated with dysregulated weight-management behaviors (i.e., eating even in the absence of hunger), which were predictive of having a high body mass index (BMI) and being obese. In both studies, findings held while controlling for participants’ current socioeconomic status, suggesting that obesity is rooted in childhood experiences. A serial mediation model in study 2 confirmed that effects of childhood SES on adult BMI and obesity can be explained in part by exposure to unpredictability, the adoption of a fast life-history strategy, and dysregulated-eating behaviors. These findings suggest that weight problems in adulthood may be rooted partially in early childhood exposure to unpredictable events and environments. LHT provides a valuable explanatory framework for understanding the root causes of obesity. PMID:28739939

2016-01-01

Objective Poor physical health in childhood is associated with a variety of negative health-related outcomes in adulthood. Psychosocial pathways contributing to the maintenance of physical health problems from childhood to young adulthood remain largely unexamined, despite evidence that factors such as negative mood and stress impact physical health. Design The current study tested the direct and indirect effects of ongoing health, chronic stress, health-related chronic stress, and depressive symptoms at age 20 on the link between health problems in childhood and young adulthood (age 21) in a longitudinal sample (n = 384). Main Outcome Measures The hypotheses were tested using a multiple mediation path analysis framework; the primary outcome measure was a composite index of health status markers in young adulthood. Results The proposed model provided an adequate fit for the data, with significant total indirect effects of the four mediators and significant specific indirect effects of health-related chronic stress and depressive symptoms in maintaining health problems from childhood into young adulthood. Conclusions Health problems are maintained from early childhood into young adulthood in part through psychosocial mechanisms. Depressive symptoms and health-related chronic stress have significant, unique effects on the relationship between health problems in early childhood and young adulthood. PMID:27329508

Although employee assistance programs are rapidly becoming the predominant vehicle for the delivery of mental health services in occupational settings, few programs employ a psychiatrist on either a part-time or a full-time basis. After providing an overview of the need for, cost-effectiveness of, and current status of employee assistance programs, the authors draw on their own experiences with employee assistance programs to present four broad categories of roles the psychiatrist can assume in such programs: clinician, supervisor and educator, administrator, and organizational consultant. Problems encountered in these roles are also discussed.

The number of immunocompromised patients and subsequent invasive fungal infections continues to rise. However, the education of future medical mycologists to engage this growing problem is diminishing. While there are an increasing number of publications and grants awarded in mycology, the time and detail devoted to teaching medical mycology in United States medical schools are inadequate. Here we review the history in medical mycology education and the current educational opportunities. To accurately gauge contemporary teaching we also conducted a prospective survey of microbiology and immunology departmental chairpersons in United States medical schools to determine the amount and content of contemporary education in medical mycology.

Asian regions have been suffering from growing double burden of nutritional health problems, such as undernutrition and chronic diseases. National nutrition survey plays an essential role in helping to improve both national and global health and reduce health disparities. The aim of this review was to compile and present the information on current national nutrition surveys conducted in Asian countries and suggest relevant issues in implementation of national nutrition surveys. Fifteen countries in Asia have conducted national nutrition surveys to collect data on nutrition and health status of the population. The information on national nutrition survey of each country was obtained from government documents, international organizations, survey website of governmental agencies, and publications, including journal articles, books, reports, and brochures. The national nutrition survey of each country has different variables and procedures. Variables of the surveys include sociodemographic and lifestyle variables; foods and beverages intake, dietary habits, and food security of individual or household; and health indicators, such as anthropometric and biochemical variables. The surveys have focused on collecting data about nutritional health status in children aged under five years and women of reproductive ages, nutrition intake adequacy and prevalence of obesity and chronic diseases for all individuals. To measure nutrition and health status of Asian populations accurately, improvement of current dietary assessment methods with various diet evaluation tools is necessary. The information organized in this review is important for researchers, policy makers, public health program developers, educators, and consumers in improving national and global health.

To compare anamnestic antibody responses of dogs and cats with current versus out-of-date vaccination status. Cross-sectional study. 74 dogs and 33 cats. Serum samples were obtained from dogs and cats that had been exposed to rabies and brought to a veterinarian for proactive serologic monitoring or that had been brought to a veterinarian for booster rabies vaccination. Blood samples were collected on the day of initial evaluation (day 0) and then again 5 to 15 days later. On day 0, a rabies vaccine was administered according to label recommendations. Paired serum samples were analyzed for antirabies antibodies by means of a rapid fluorescent focus inhibition test. All animals had an antirabies antibody titer ≥ 0.5 IU/mL 5 to 15 days after booster vaccination. Dogs with an out-of-date vaccination status had a higher median increase in titer, higher median fold increase in titer, and higher median titer following booster vaccination, compared with dogs with current vaccination status. Most (26/33) cats, regardless of rabies vaccination status, had a titer ≥ 12 IU/mL 5 to 15 days after booster vaccination. Results indicated that dogs with out-of-date vaccination status were not inferior in their antibody response following booster rabies vaccination, compared with dogs with current vaccination status. Findings supported immediate booster vaccination followed by observation for 45 days of dogs and cats with an out-of-date vaccination status that are exposed to rabies, as is the current practice for dogs and cats with current vaccination status.

Mental problems and their potential socio-demographic determinants were investigated in young schoolchildren in Sweden, a high-income country in the top of income- and gender-equality rankings. Cross-sectional study of 1465 schoolchildren in grades 3 and 6. Mental health was measured by the Child Behavior Checklist and the Youth Self Report (Total problems and 14 specific problem areas). Potential socio-demographic determinants were sex, parental education and occupation, family structure, and immigrant status. Mental problems were present in 14% of the sixth graders and in 7% of the third graders. In grade 3, the mean total problem score was lower in girls than in boys, but the prevalence of problems at a subclinical/clinical level did not differ by sex. Furthermore, in nine to 13 of the 14 specific problem areas, problems were equally distributed by sex, parental education, parental occupation, immigrant status, and family structure. In grade 6, both the total mean score and the overall odds of subclinical/clinical problems were similar in girls and boys. Likewise, in all the specific problem areas, problems were evenly distributed by parental education and occupation, and only independently associated with immigrant status and family structure in one problem area. In five specific problem areas, boys had higher odds of problems than girls. This study shows that also in a relatively wealthy and equal country such as Sweden, mental problems are a significant child public health issue. The association between socio-demographic background and mental problems seems to be rather weak, but differ dependent on the type of mental problem in focus. © 2015 the Nordic Societies of Public Health.

Effects of management tactics on meeting conservation objectives for Western North American groundfish fisheries.

Melnychuk, Michael C; Banobi, Jeannette A; Hilborn, Ray

2013-01-01

There is considerable variability in the status of fish populations around the world and a poor understanding of how specific management characteristics affect populations. Overfishing is a major problem in many fisheries, but in some regions the recent tendency has been to exploit stocks at levels below their maximum sustainable yield. In Western North American groundfish fisheries, the status of individual stocks and management systems among regions are highly variable. In this paper, we show the current status of groundfish stocks from Alaska, British Columbia, and the U.S. West Coast, and quantify the influence on stock status of six management tactics often hypothesized to affect groundfish. These tactics are: the use of harvest control rules with estimated biological reference points; seasonal closures; marine reserves; bycatch constraints; individual quotas (i.e., 'catch shares'); and gear type. Despite the high commercial value of many groundfish and consequent incentives for maintaining stocks at their most productive levels, most stocks were managed extremely conservatively, with current exploitation rates at only 40% of management targets and biomass 33% above target biomass on average. Catches rarely exceeded TACs but on occasion were far below TACs (mean catch:TAC ratio of 57%); approximately $150 million of potential landed value was foregone annually by underutilizing TACs. The use of individual quotas, marine reserves, and harvest control rules with estimated limit reference points had little overall effect on stock status. More valuable fisheries were maintained closer to management targets and were less variable over time than stocks with lower catches or ex-vessel prices. Together these results suggest there is no single effective management measure for meeting conservation objectives; if scientifically established quotas are set and enforced, a variety of means can be used to ensure that exploitation rates and biomass levels are near to or more conservative than management targets.

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

Latino Immigrants’ Biological Parents’ Histories Of Substance Use Problems In Their Country Of Origin Predict Their Pre- And Post-Immigration Alcohol Use Problems

Blackson, Timothy C.; De La Rosa, Mario; Sanchez, Mariana; Li, Tan

2014-01-01

Background No studies to date have assessed whether recent young adult (ages 18–34) Latino immigrants’ biological parents’ histories of substance use problems (BPHSUP) in their country of origin predict their alcohol use problems at pre- and post-immigration to the United States (U.S.). Methods BPHSUP in their country of origin was assessed via interviews conducted by bilingual Latino researchers with recent Latino immigrants primarily from Cuba, Central and South America recruited through respondent driven sampling at the time of their immigration to southeastern U.S. Three-waves of data were collected to document Latino immigrants’ severity of alcohol use problems at pre-immigration and two annual post-immigration follow-up assessments. BPHSUP +/− status was used as a predictor of Latinos’ (N=452; 45.8% female, 54.2% male) Alcohol Use Disorders Identification Test (AUDIT) scores at pre- and post-immigration with age, education and income as covariates as wells as odds ratios for AUDIT classifications of hazardous use, harmful use and dependence. Results BPHSUP+ status predicted Latino immigrants’ higher AUDIT scores pre- and post-immigration by gender (p<.01) compared to Latino immigrants of BPHSUP− status controlling for age, education and income. BPHSUP+ status predicted odds ratios of 3.45 and 2.91 for alcohol dependence AUDIT classification for men and women respectively (T3). Conclusions This study documents that BPHSUP +/− status in their country of origin predict their young adult Latino offspring’s severity of alcohol use problems pre-and post-immigration. These results may inform (1) community-based health care providers to screen recent young adult Latino immigrants for their BPHSUP+/− status and severity of alcohol use problems to redirect trajectories away from alcohol use disorders toward more normative post-immigration outcomes through culturally relevant prevention services and (2) future research advantages of differential susceptibility theory. Implications for future research and the need for replication studies in other geographic regions of the U.S. are discussed. PMID:24960302

SPECIAL SECTION: Perspectives of the Scientific Community on the Status of Ecological Risk Assessment

PubMed

Power; Adams

1997-11-01

/ Views from a wide variety of practicing environmental professionals on the current status of ecological risk assessment (ERA) indicate consensus and divergence of opinion on the utility and practice of risk assessment. Central to the debate were the issues of whether ERA appropriately incorporates ecological and scientific principle into its conceptual paradigm. Advocates argue that ERA effectively does both, noting that much of the fault detractors find with the process has more to do with its practice than its purpose. Critics argue that failure to validate ERA predictions and the tendency to over-simplify ecological principles compromise the integrity of ERA and may lead to misleading advice on the appropriate responses to environmental problems. All authors felt that many improvements could be made, including validation, better definition of the ecological questions and boundaries of ERA, improved harmonization of selected methods, and improvements in the knowledge base. Despite identified deficiencies, most authors felt that ERA was a useful process undergoing evolutionary changes that will inevitably determine the range of environmental problems to which it can be appropriately applied. The views expressed give ERA a cautious vote of approval and highlight many of the critical strengths and weaknesses in one of our most important environmental assessment tools.KEY WORDS: Ecological risk assessment; Ecology; Probability

Alzheimer’s disease (AD) shows a marked presence of physiologic changes and the start or aggravation of underlying diseases such as physical frailty in diverse anatomical regions. It is believed to have a particularly harmful effect on the health of the foot. We examined the foot health status in older persons with AD, with a specific focus on the extent to which people with AD may be using inadequate footwear in old age. Seventy-three community-dwelling people with probable, mild to moderate AD aged 65–95 years were recruited from a center of excellence for AD. A single trained physician evaluated health status and foot conditions. Current shoe and foot length and width measurements were taken using a calibrated Brannock device. The results indicate that sixty-five participants (89.04%) suffered from feet problems. Also, only twenty-two subjects (30.14%) used the correct shoes in width and size related with the morphology of their feet. Fifty-one participants (69.86%) were using incorrect shoes in length or width. The present study revealed that peoples with AD had a high presence of foot health problems. Also, the use of inappropriate shoes revealed measurable differences of association between shoe size and the morphology of the foot. PMID:29414905

Automobiles have become essential parts of our everyday lives. It can correlate many factors that may affect a vehicle primarily those which may inconvenient or in some cases harm lives or properties. Thus, focusing on detecting an automatic transmission vehicle engine, body and other parts that cause vibration and sound may help prevent car problems using MATLAB. By using sound, vibration, and temperature sensors to detect the defects of the car and with the help of the transmitter and receiver to gather data wirelessly, it is easy to install on to the vehicle. A technique utilized from Toyota Balintawak Philippines that every car is treated as panels(a, b, c, d, and e) 'a' being from the hood until the front wheel of the car and 'e' the rear shield to the back of the car, this was applied on how to properly place the sensors so that precise data could be gathered. Data gathered would be compared to the normal graph taken from the normal status or performance of a vehicle, data that would surpass 50% of the normal graph would be considered that a problem has occurred. The system is designed to prevent car accidents by determining the current status or performance of the vehicle, also keeping people away from harm.

In recent years, a number of studies focusing on the evaluation of neuropsychological deficits in individuals with schizophrenia have shown deficits that include several cognitive functions. Attention deficits as well as memory or executive function deficits are common in this kind of disorder together with sustained attention problems, working memory deficiencies, and problem-solving difficulties, among many others. Currently, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is gaining special importance in the evaluation of the cognitive deficits associated with schizophrenia. In this article, we describe an RBANS screening in a sample of 88 Spanish patients diagnosed with schizophrenia. We also aimed to check the battery's reliability, sensitivity, and specificity in the studied sample. We performed a comparative study with 88 healthy participants. The results showed a reliability index value of α = .795 and an item value of α = .762. For total test reliability, we obtained an index value of α = .761 and an item value of α = .762. Sensitivity score was 87.5% and specificity 86.4%. RBANS obtained good reliability, sensitivity, and specificity scores and represents a good screening tool in detecting cognitive deficits associated with schizophrenia. © The Author(s) 2015.

2016-01-01

This review the status of genetic laboratory testing in Prader-Willi syndrome (PWS) due to different genetic subtypes, most often a paternally derived 15q11-q13 deletion, with benefits and limitations related to prenatal screening. Medical literature was searched for prenatal screening and genetic laboratory testing methods in use or under development and discussed in relationship to PWS. Genetic testing includes six established laboratory diagnostic approaches for PWS with direct application to prenatal screening. Ultrasonographic, obstetric and cytogenetic reports were summarized in relationship to the cause of Prader-Willi syndrome and identification of specific genetic subtypes including maternal disomy 15. Advances in genetic technology were described for diagnosing PWS specifically DNA methylation and high-resolution chromosomal SNP microarrays as current tools for genetic screening and incorporating next generation DNA sequencing for noninvasive prenatal testing (NIPT) using cell-free fetal DNA. Positive experiences are reported with NIPT for detection of numerical chromosomal problems (aneuploidies) but not for structural problems (microdeletions). These reports will be discussed along with future directions for genetic screening of PWS. In summary, this review describes and discusses the status of established and ongoing genetic testing options for PWS applicable in prenatal screening including NIPT and future directions for early diagnosis in Prader-Willi syndrome.

To examine the strength of associations between child oral health and aspects of the home environment (child behaviour, parental psychological distress and family functioning) in a large sample of 1- to 12-year-old Australian children. The current study used data from the 2006 Victorian Child Health and Wellbeing Study. Data were obtained on 4590 primary carers. Measures of the family environment included the level of family functioning, parental psychological distress, child's emotion and behavioural problems and the family structure. The odds of children having good oral health status were lower with increasing parental psychological distress and poor family functioning across all age groups, and lower with increasing child mental health or conduct problems among children aged 4 years or older. Socioeconomic factors were also related to child oral health status, but this was significant only among children aged 4-7 years, with the odds of children having good oral health status 68% higher in households with a yearly income ≥AUD$ 60 000 compared with households with income <$20 000 (P < 0.05). In order to address inequities in the experience of poor oral health, solutions that encompass social, economic and psychosocial dimensions will be required. Integrating intervention strategies that promote oral, healthy family functioning and the mental health of parents and children into existing systems reaching vulnerable community members may improve child oral health outcomes and reduce the unequal distribution of oral disease across the social gradient. © 2013 John Wiley & Sons Ltd.

Depression is currently underdiagnosed among older adults. As part of the Novel Assessment of Nutrition and Aging (NANA) validation study, 40 older adults self-reported their mood using a touchscreen computer over three, one-week periods. Here, we demonstrate the potential of these data to predict future depression status. We analysed data from the NANA validation study using a machine learning approach. We applied the least absolute shrinkage and selection operator with a logistic model to averages of six measures of mood, with depression status according to the Geriatric Depression Scale 10 weeks later as the outcome variable. We tested multiple values of the selection parameter in order to produce a model with low deviance. We used a cross-validation framework to avoid overspecialisation, and receiver operating characteristic (ROC) curve analysis to determine the quality of the fitted model. The model we report contained coefficients for two variables: sadness and tiredness, as well as a constant. The cross-validated area under the ROC curve for this model was 0.88 (CI: 0.69-0.97). While results are based on a small sample, the methodology for the selection of variables appears suitable for the problem at hand, suggesting promise for a wider study and ultimate deployment with older adults at increased risk of depression. We have identified self-reported scales of sadness and tiredness as sensitive measures which have the potential to predict future depression status in older adults, partially addressing the problem of underdiagnosis.

To evaluate the application status of China Disease Prevention and Control Information System of Hydatid Disease, in which questions existed are summarized in order to promote the system update. A questionnaire was designed and distributed to Inner Mongolia, Sichuan, Tibet, Gansu, Qinghai, Ningxia, Xinjiang and Xinjiang Production and Construction Corps to evaluate the application status of China Disease Prevention and Control Information System of Hydatid Disease assistant with telephone. The recovery rate of questionnaires was 87.5%. The statistics of closed questions showed that national application rate of the China Disease Prevention and Control Information System of Hydatid Disease was 100%, of which 15.3% were low frequency users, 57.1% believed the system was necessary, 28.6% considered it was dispensable, and 14.3% believed that it was totally unnecessary. The statistics of open-ended questions indicated that 6 endemic regions suggested to increase the guidance and training, while 4 endemic regions had opinions on sharing the information of the national infectious disease reporting systems and hydatid disease prevention and control information system, and the opinions on turning monthly report to quarterly report, and increasing statistics and analysis module, and 3 endemic regions deemed that the system had logic errors and defects. The problems of the system are mainly focused on the existence of systemic deficiencies and logic errors, lacking of statistical parameters and corresponding analysis function module, and lacking of the guidance and training, which limits the use of the system. Therefore, these problems should be resolved.

Background Social determinants of sleep may prove to be as important as health status. In this study we examined the extent to which persistent and changing economic difficulties are associated with sleep problems in two prospective occupational cohorts. Methods We used data from Finnish (baseline 2000–2002; follow-up 2007; n = 6328) and British (baseline 1997–1999; follow-up 2003–2004; n = 5002) public sector employees. Economic difficulties, sleep problems, and a variety of covariates were assessed at baseline and follow-up. Results Prevalence of frequent sleep problems at follow-up was 27% and 20% among women and men in the Finnish cohort, and 34% and 27% in the British cohort, respectively. Odds for sleep problems were higher among those with persistent economic difficulties (frequent economic difficulties at baseline and follow-up) compared to those with no difficulties. This association remained after multiple adjustments, including parental and current socioeconomic position, in the Finnish (OR 1.72, 95% CI 1.35–2.18) cohort. Increases in economic difficulties were similarly associated with sleep problems in the Finnish and the British cohort. Conclusion Evidence from two occupational cohorts suggests strong associations between economic difficulty and poor sleep. Awareness of this association will help health care professionals identify and prevent sleep problems. PMID:22445231

Problem and pathological gambling refers to subclinical and clinical levels of maladaptive gambling, respectively, and is associated with specific sociodemographic characteristics as well as a number of poor health outcomes. We examined such demographic, physical health, mental health, and health-related behaviors in a sample of 7045 low-risk gamblers and 244 problem/pathological gamblers. Participants completed the 2014 North Carolina Behavioral Risk Factor Surveillance System telephone survey. Using the National Opinion Research Center's Diagnostic Screen for Gambling Disorders-CLiP, participants were categorized as either "problem/pathological gamblers" or "low-risk gamblers." Problem/pathological gamblers were younger, more likely to be male, of ethnic minority status, unmarried, and of lower education than low-risk gamblers. No physical health variables differentiated the groups but problem/pathological gamblers reported experiencing significantly more adverse childhood experiences and engaging in significantly more tobacco and alcohol use compared to low-risk gamblers. Moreover, gender moderated relationships between gambling group and several of the alcohol use variables such that male problem/pathological gamblers exhibited greater alcohol use behavior than male low-risk gamblers but no such relationship was present in females. Overall, this study expands the current knowledgebase on disordered gambling and highlights the need to assess disordered gambling in public health samples. Clinical implications are discussed.

Pro-community altruism and social status in a Shuar village.

PubMed

Price, Michael E

2003-06-01

Reciprocity theory (RT) and costly signaling theory (CST) provide different explanations for the high status of pro-community altruists: RT proposes that altruists are positively and negatively sanctioned by others, whereas CST proposes that altruists are attractive to others. Only RT, however, is beset by first- and higher-order free rider problems, which must be solved in order for RT to explain status allocations. In this paper, several solutions to RT's free rider problems are proposed, and data about status allocations to Ecuadorian Shuar pro-community altruists are analyzed in light of RT and CST. These data confirm that perceived pro-community altruists are indeed high status and suggest that (1) community residents skillfully monitor the altruism of coresidents, (2) residents who engage in opportunities to broadcast desirable qualities are high status only to the extent that they are considered altruistic, and (3) individuals who sanction coresidents based on coresidents' contributions to the community are themselves relatively high status. To a greater extent than CST, RT straightforwardly predicts all of these results.

About seven million people in Germany are affected by overindebtedness and insolvency. Being severely in debt is a very stressful situation that can result in social marginalisation, reducted overall activity, and physical and mental illness. The present study investigated the frequency of financial problems and their effects on physical and mental disorders at a university psychosomatic clinic. The study included a total of 659 patients. Their mental status was assessed with the Symptom Checklist (SCL-90-R), their physical status with the Gießener Beschwerdebogen (GBB). 37 percent of the subjects reported experiencing financial problems. We found that subjects with financial problems reported more physical and mental disorders than those without financial problems. Furthermore, therapists more often recommended that patients with financial problems receive inpatient therapy than patients without financial problems. The study suggests that financial problems should be included in any anamnesis, therapeutic recommendation, and actual therapy of patients in psychosomatic treatment.
