    The Alexander von Humboldt Conference Series of the European Geosciences Union are a series of meetings held outside of Europe, in particular in South America, Africa or Asia, on selected topics of geosciences with a socio-economic impact for regions on these continents, jointly organised with the scientists and their institutes and the institutions of these regions. Given the increasing success of the GIFT workshops held in conjunction with the General Assemblies, since 2010 EGU has also developed a series of GIFT workshops held in conjunction with AvH conferences. Associated GIFT workshops were held in Merida, Yucatan, on the theme of Climate Change, Natural Hazards and Societies (March 2010), then in Penang, Malaysia (June 2011) on the theme of Ocean Acidification, in November 2012 in Cusco (Peru) on the theme of Natural Disasters, Global Change and the Preservation of World Heritage Sites, finally in Istanbul (March 2014) on "High Impact Natural Hazards Related to the Euro-Mediterranean Region. The next GIFT workshop is already planned for October 2015 in Adis Ababa (Ethiopia) on the theme "Water". In each case, the GIFT workshop was held on the last two days of the AvH conference and reunited 40-45 teachers from the nation where the AvH was held. Keynote speakers from AvH were speakers to the GIFT workshops which also included hands-on activities animated by sciences educators. These GIFT workshops represented the first workshops specifically aimed at teachers held in the country, and therefore represents a significant Earth Sciences contribution to secondary education in non European countries.

    Auditory verbal hallucinations (AVH) are the most prevalent symptom in schizophrenia. They are associated with increased activation within the temporoparietal cortices and are refractory to pharmacological and psychological treatment in approximately 25% of patients. Low frequency repetitive transcranial magnetic stimulation (rTMS) over the temporoparietal cortex has been demonstrated to be effective in reducing AVH in some patients, although results have varied. The cortical mechanism by which rTMS exerts its effects remain unknown, although data from the motor system is suggestive of a local cortical inhibitory effect. We explored neuroimaging differences in healthy volunteers between application of a clinically utilized rTMS protocol and a sham rTMS equivalent when undertaking a prosodic auditory task.

    Aloe barbadensis Mill. (Aloe vera) is a widely used medicinal plant well reputed for its diverse therapeutic applications. It has been used for thousands of years in folk medicine to treat various conditions and the Aloe vera gel has been reported to possess anti-inflammatory as well as immunostimulatory and immunomodulatory properties. However, the mode of action is still unclear. The aim of this study was determine the effects of two well-defined A. barbadensis Mill. extracts AVH200® and AVE200 on human blood T cells in vitro. Peripheral blood mononuclear cells (PBMC) from healthy donors were stimulated polyclonally in the presence or absence of AVH200® and AVE200. The T cell phenotype was investigated by flow cytometry, cell proliferation was determined by CFSE dye and thymidine assay, respectively and cytokine secretion was determined by MSD® Multi-Spot Assay system and ELISA. The presence of AVH200® resulted in a reduced expression of CD25 among CD3(+) T cells and suppression of T cell proliferation in a dose dependent manner. Furthermore, AVH200® reduced the expression of CD28 on CD3(+) T cells. AVH200® also reduced the secretion of IL-2, IFN-γ and IL-17A in PBMC cultures. The AVH200® dose dependent reduction in T cell activation and proliferation recorded in the cell cultures was not due to apoptosis or cell death. Additionally, AVH200® was found to be more effective as compared to AVE200 in reducing T cell activation and proliferation. AVH200® has the potential to reduce the activation, proliferation and cytokine secretion of healthy human blood T cells. Our study suggests that AVH200® has a suppressive effect on human blood T cells in vitro. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    In Uzbekistan, routine serologic testing has not been available to differentiate etiologies of acute viral hepatitis (AVH). To determine the age groups most affected by hepatitis E virus (HEV) during documented AVH epidemics, trends in AVH-associated mortality rate (MR) per 100,000 over a 15-year period and reported incidence of AVH over a 35-year period were examined. Reported AVH incidence data from 1971 to 2005 and AVH-associated mortality data from 1981 to 1995 were examined. Serologic markers for infection with hepatitis viruses A, B, D, and E were determined from a sample of hospitalized patients with AVH from an epidemic period (1987) and from a sample of pregnant women with AVH from a non-epidemic period (1992). Two multi-year AVH outbreaks were identified: one during 1975-1976, and one during 1985-1987. During 1985-1987, AVH-associated MRs were 12.3-17.8 per 100,000 for the general population. Highest AVH-associated MRs occurred among children in the first 3 years of life (40-190 per 100,000) and among women aged 20-29 (15-21 per 100,000). During 1988-1995 when reported AVH morbidity was much lower in the general population, AVH-associated MRs were markedly lower among these same age groups. In 1988, AVH-associated MRs were higher in rural (21 per 100,000) than in urban (8 per 100,000) populations (RR 2.6; 95% CI 1.16-5.93; p Uzbekistan during 1985-1987. High mortality among pregnant women but not among children less than 3 years has been observed in previous descriptions of epidemic hepatitis E. The high mortality among younger children observed in an AVH outbreak associated with hepatitis E merits corroboration in future outbreaks.

    Full Text Available Research on auditory verbal hallucinations (AVHs indicates that AVH schizophrenia patients show greater abnormalities on tasks requiring recognition of affective prosody (AP than non-AVH patients. Detecting AP requires accurate perception of manipulations in pitch, amplitude and duration. Schizophrenia patients with AVHs also experience difficulty detecting these acoustic manipulations; with a number of theorists speculating that difficulties in pitch, amplitude and duration discrimination underlie AP abnormalities. This study examined whether both AP and these aspects of auditory processing are also impaired in first degree relatives of persons with AVHs. It also examined whether pitch, amplitude and duration discrimination were related to AP, and to hallucination proneness. Unaffected relatives of AVH schizophrenia patients (N=19 and matched healthy controls (N=33 were compared using tone discrimination tasks, an AP task, and clinical measures. Relatives were slower at identifying emotions on the AP task (p =.002, with secondary analysis showing this was especially so for happy (p = .014 and neutral (p =.001 sentences. There was a significant interaction effect for pitch between tone deviation level and group (p = .019, and relatives performed worse than controls on amplitude discrimination and duration discrimination. AP performance for happy and neutral sentences was significantly correlated with amplitude perception. Lastly, AVH proneness in the entire sample was significantly correlated with pitch discrimination (r = .44 and pitch perception was shown to predict AVH proneness in the sample (p = .005. These results suggest basic impairments in auditory processing are present in relatives of AVH patients; they potentially underlie processing speed in AP tasks, and predict AVH proneness. This indicates auditory processing deficits may be a core feature of AVHs in schizophrenia, and are worthy of further study as a potential endophenotype for

    Whilst evidence is mounting that childhood sexual abuse (CSA) can be a cause of auditory verbal hallucinations (AVH), it is unclear what factors mediate this relation. Recent evidence suggests that post-traumatic symptomatology may mediate the CSA-AVH relation in clinical populations, although this hypothesis has not yet been tested in the general population. There is also reason to believe that obsessive ideation could mediate the CSA-AVH relation. To test for evidence to falsify the hypotheses that post-traumatic symptomatology, obsessions, compulsions, anxiety and depression mediate the relation between CSA and AVH in a general population sample. Indirect effects of CSA on AVH via potential mediators were tested for, using a regression-based approach employing data from the 2007 Adult Psychiatric Morbidity Survey (n = 5788). After controlling for demographics, IQ and child physical abuse, it was found that CSA, IQ, post-traumatic symptomatology and compulsions predicted lifetime experience of AVH. Mediation analyses found significant indirect effects of CSA on AVH via post-traumatic symptomatology [odds ratio (OR): 1.11; 95% confidence interval (CI):1.00-1.29] and compulsions (OR: 1.10, 95% CI: 1.01-1.28). These findings offer further support for the hypothesis that post-traumatic symptomatology is a mediator of the CSA-AVH relation. Although no evidence was found for obsessional thoughts as a mediating variable, a potential mediating role for compulsions is theoretically intriguing. This study's findings reiterate the need to ask about experiences of childhood adversity and post-traumatic symptomology in people with AVH, as well as the likely therapeutic importance of trauma-informed and trauma-based interventions for this population.

    Few effective treatment options exist for patients with irritable bowel syndrome (IBS), and many patients state the use of aloe vera products reduce their symptoms. The aim of this pilot study was to investigate the effect of Aloe barbadensis Mill. Extract (AVH200®) in adult patients with IBS in a randomized, double-blind, placebo controlled study. Sixty-eight adult patients diagnosed with IBS according to the Rome III criteria were randomized to receive AVH200® or matching placebo for four weeks. Symptom questionnaires were completed on a weekly basis and the patients were asked if they had had adequate relief of their gastrointestinal symptoms. A tendency towards a higher proportion of responders in the aloe vera group (55%) vs. placebo (31%), (p=0.09) was observed, and the proportion of subjects who reported adequate relief at least 50% of the weeks during the treatment period tended to be larger in the aloe vera vs. placebo group (33% vs. 14%; p=0.12). The overall severity of the gastrointestinal symptoms was reduced in the aloe vera group (314+/-83 vs. 257+/-107; p=0.003) but not the placebo group (276+/-88 vs. 253+/-100; NS), without difference between the groups (p=0.10). AVH200® was well tolerated and no serious adverse events were observed. Even though the primary endpoint was not met, AVH200® seems to be a promising treatment option for patients with IBS owing to the positive results seen within the secondary endpoints. This study may have been underpowered to detect a clinically meaningful difference between the treatment groups, and therefore larger randomized, controlled studies are required to confirm these results and to elucidate potential mechanisms explaining its effect.

  9. Functional MRI Evaluation of Multiple Neural Networks Underlying Auditory Verbal Hallucinations in Schizophrenia Spectrum Disorders

    Full Text Available Functional MRI studies have identified a distributed set of brain activations to be associated with auditory verbal hallucinations (AVH. However, very little is known about how activated brain regions may be linked together into AVH-generating networks. Fifteen volunteers with schizophrenia or schizoaffective disorder pressed buttons to indicate on-set and off-set of AVH during fMRI scanning. When a general linear model (GLM was used to compare BOLD signals during periods in which subjects indicated that they were versus were not experiencing AVH (‘AVH-on’ versus ‘AVH-off’, it revealed AVH-related activity in bilateral inferior frontal and superior temporal regions; the right middle temporal gyrus; and the left insula, supramarginal gyrus, inferior parietal lobule and extra-nuclear white matter. In an effort to identify AVH-related networks, the raw data were also processed using independent component analyses (ICA. Four ICA components were spatially consistent with an a priori network framework based upon published meta-analyses of imaging correlates of AVH. Of these four components, only a network involving bilateral auditory cortices and posterior receptive language areas was significantly and positively correlated with the pattern of AVH-on versus AVH-off. The ICA also identified two additional networks (occipital-temporal and medial pre-frontal, not fully matching the meta-analysis framework, but nevertheless containing nodes reported as active in some studies of AVH. Both networks showed significant AVH-related profiles, but both were most active during AVH-off periods. Overall, the data suggest that AVH generation requires specific and selective activation of auditory cortical and posterior language regions, perhaps coupled to a release of indirect influence by occipital and medial frontal structures.

    Full Text Available Auditory verbal hallucinations (AVH or ‘voices’ are a characteristic symptom of schizophrenia, but can also be observed in healthy individuals in the general population. As these non-psychotic individuals experience AVH in the absence of other psychiatric symptoms and medication-use they provide an excellent model to study AVH in isolation. Indeed a number of studies used this approach and investigated brain structure and function in non-psychotic individuals with AVH.These studies showed that aberrant connectivity of language production and perception areas is particularly associated with AVH. This is in concordance with investigations that observed prominent activation of these language areas during the state of AVH. Effortful attention decreased cerebral dominance for language and dopamine dysfunction on the other hand, are presumably not specifically related to AVH.

    The host response in hepatitis E virus (HEV)-related liver disease of pregnant women is unclear. This study was carried out to evaluate the serum concentration of tumor necrosis factor (TNF)-α in HEV-related acute viral hepatitis (AVH) and fulminant hepatic failure (FHF) in pregnant women in relation to pregnancy outcome. The study included 262 pregnant and 158 non-pregnant women with jaundice. There were 160 healthy asymptomatic pregnant women and 124 healthy asymptomatic non-pregnant women as controls. The jaundiced patients were classified as AVH or FHF. Serum TNF-α level was assayed by commercially available enzyme-linked immunoassay kits. A significantly higher level of TNF-α was observed in HEV-infected pregnant women than non-HEV pregnant women (P pregnant women compared with AVH and FHF of HEV infected non-pregnant women (P = 0.036 and P = 0.010, respectively). The HEV-infected pregnant FHF expired group had significantly higher levels of TNF-α than the non-pregnant FHF expired group (P = 0.025). TNF-α levels were significantly higher in AVH of HEV-infected pregnant women than healthy pregnant controls (P women having preterm delivery and low birthweight newborns compared with non-HEV and healthy pregnant women. Higher serum concentration of TNF-α observed in HEV infected AVH and FHF pregnant cases shows that pregnancy with HEV infection increases TNF-α secretion. TNF-α may be an important factor in the outcomes of pregnancy due to HEV infection. © 2012 The Japan Society of Hepatology.

  15. Auditory verbal hallucinations in schizophrenia and post-traumatic stress disorder: common phenomenology, common cause, common interventions?

    2015-01-01

    Auditory verbal hallucinations (AVH: ‘hearing voices’) are found in both schizophrenia and post-traumatic stress disorder (PTSD). In this paper we first demonstrate that AVH in these two diagnoses share a qualitatively similar phenomenology. We then show that the presence of AVH in schizophrenia is often associated with earlier exposure to traumatic/emotionally overwhelming events, as it is by definition in PTSD. We next argue that the content of AVH relates to earlier traumatic events in a similar way in both PTSD and schizophrenia, most commonly having direct or indirect thematic links to emotionally overwhelming events, rather than being direct re-experiencing. We then propose, following cognitive models of PTSD, that the reconstructive nature of memory may be able to account for the nature of these associations between trauma and AVH content, as may threat-hypervigilance and the individual’s personal goals. We conclude that a notable subset of people diagnosed with schizophrenia with AVH are having phenomenologically and aetiologically identical experiences to PTSD patients who hear voices. As such we propose that the iron curtain between AVH in PTSD (often termed ‘dissociative AVH’) and AVH in schizophrenia (so-called ‘psychotic AVH’) needs to be torn down, as these are often the same experience. One implication of this is that these trauma-related AVH require a common trans-diagnostic treatment strategy. Whilst antipsychotics are already increasingly being used to treat AVH in PTSD, we argue for the centrality of trauma-based interventions for trauma-based AVH in both PTSD and in people diagnosed with schizophrenia.

    Threat-related automatic associations are assumed to play an important role in the development and maintenance of social anxiety. We tested whether threat-related automatic associations are already evident in high socially anxious adolescents, by comparing a group of adolescents (age 12-15) with subclinical levels of social anxiety (n=170) to a group of low socially anxious adolescents (n=193). We used a single-target implicit association test to measure threat-related automatic associations to social cues. Results showed that indeed in high socially anxious adolescents social cues automatically elicited relatively strong threat-related associations. Supporting the relevance of differentiating between automatic and more explicit measures, both automatic and explicit associations were independently associated with adolescents' level of self-reported social anxiety. The present pattern of findings is not only consistent with the view that automatic and more deliberate threat-related associations are both involved in the etiology of social-anxiety symptoms, but also suggest that both types of associations are proper targets for early intervention programs.

    Diverse pathogens secrete effector proteins into plant cells to manipulate host cellular processes. Oomycete pathogens contain large complements of predicted effector genes defined by an RXLR host cell entry motif. The genome of Hyaloperonospora arabidopsidis (Hpa, downy mildew of Arabidopsis) contains at least 134 candidate RXLR effector genes. Only a small subset of these genes is conserved in related oomycetes from the Phytophthora genus. Here, we describe a comparative functional characterization of the Hpa RXLR effector gene HaRxL96 and a homologous gene, PsAvh163, from the Glycine max (soybean) pathogen Phytophthora sojae. HaRxL96 and PsAvh163 are induced during the early stages of infection and carry a functional RXLR motif that is sufficient for protein uptake into plant cells. Both effectors can suppress immune responses in soybean. HaRxL96 suppresses immunity in Nicotiana benthamiana, whereas PsAvh163 induces an HR-like cell death response in Nicotiana that is dependent on RAR1 and Hsp90.1. Transgenic Arabidopsis plants expressing HaRxL96 or PsAvh163 exhibit elevated susceptibility to virulent and avirulent Hpa, as well as decreased callose deposition in response to non-pathogenic Pseudomonas syringae. Both effectors interfere with defense marker gene induction, but do not affect salicylic acid biosynthesis. Together, these experiments demonstrate that evolutionarily conserved effectors from different oomycete species can suppress immunity in plant species that are divergent from the source pathogen's host. © 2012 The Authors.

  1. Auditory/Verbal hallucinations, speech perception neurocircuitry, and the social deafferentation hypothesis.

    Science.gov (United States)

    Hoffman, Ralph E

    2008-04-01

    Auditory/verbal hallucinations (AVHs) are comprised of spoken conversational speech seeming to arise from specific, nonself speakers. One hertz repetitive transcranial magnetic stimulation (rTMS) reduces excitability in the brain region stimulated. Studies utilizing 1-Hz rTMS delivered to the left temporoparietal cortex, a brain area critical to speech perception, have demonstrated statistically significant improvements in AVHs relative to sham simulation. A novel mechanism of AVHs is proposed whereby dramatic pre-psychotic social withdrawal prompts neuroplastic reorganization by the "social brain" to produce spurious social meaning via hallucinations of conversational speech. Preliminary evidence supporting this hypothesis includes a very high rate of social withdrawal emerging prior to the onset of frank psychosis in patients who develop schizophrenia and AVHs. Moreover, reduced AVHs elicited by temporoparietal 1-Hz rTMS are likely to reflect enhanced long-term depression. Some evidence suggests a loss of long-term depression following experimentally-induced deafferentation. Finally, abnormal cortico-cortical coupling is associated with AVHs and also is a common outcome of deafferentation. Auditory/verbal hallucinations (AVHs) of spoken speech or "voices" are reported by 60-80% of persons with schizophrenia at various times during the course of illness. AVHs are associated with high levels of distress, functional disability, and can lead to violent acts. Among patients with AVHs, these symptoms remain poorly or incompletely responsive to currently available treatments in approximately 25% of cases. For patients with AVHs who do respond to antipsychotic drugs, there is a very high likelihood that these experiences will recur in subsequent episodes. A more precise characterization of underlying pathophysiology may lead to more efficacious treatments.

    Bullying is a public health concern for the school-aged population, however, the health outcomes associated with the subtype of relational bullying are less understood. The purpose of this study was to examine the association between relational bullying and health-related quality of life (HRQL) among young people. This study utilized data from 5335 students aged 11-15 years, collected as part of the 2014 Health Behavior in School-aged Children (HBSC) study conducted in England. Data were collected through self-completed surveys. Multilevel analysis modeled the relationship between relational bullying and HRQL. Demographic variables (sex, age, ethnicity, socioeconomic status) and other forms of bullying were controlled for. Experiencing relational bullying had a significant negative association with HRQL whilst controlling for other forms of bullying. Weekly relational bullying resulted in an estimated 5.352 (95% confidence interval (CI), -4.178, -6.526) decrease in KIDSCREEN-10 score compared with those not experiencing relational bullying. Experiencing relational bullying is associated with poorer HRQL. The findings question the perception of relational bullying as being a predominantly female problem. Girls were more likely to report experiencing relational bullying, but the negative association with HRQL was equal for boys and girls. © 2017, American School Health Association.

    2012-01-01

    In this paper we are approaching, from a computational perspective, the problem of promoter sequences prediction, an important problem within the field of bioinformatics. As the conditions for a DNA sequence to function as a promoter are not known, machine learning based classification models are still developed to approach the problem of promoter identification in the DNA. We are proposing a classification model based on relational association rules mining. Relational association rules are a particular type of association rules and describe numerical orderings between attributes that commonly occur over a data set. Our classifier is based on the discovery of relational association rules for predicting if a DNA sequence contains or not a promoter region. An experimental evaluation of the proposed model and comparison with similar existing approaches is provided. The obtained results show that our classifier overperforms the existing techniques for identifying promoter sequences, confirming the potential of our proposal. PMID:22563233

    Directory of Open Access Journals (Sweden)

    Paradowski Mariusz

    2015-09-01

    Full Text Available Over a century of research has resulted in a set of more than a hundred binary association measures. Many of them share similar properties. An overview of binary association measures is presented, focused on their order equivalences. Association measures are grouped according to their relations. Transformations between these measures are shown, both formally and visually. A generalization coefficient is proposed, based on joint probability and marginal probabilities. Combining association measures is one of recent trends in computer science. Measures are combined in linear and nonlinear discrimination models, automated feature selection or construction. Knowledge about their relations is particularly important to avoid problems of meaningless results, zeroed generalized variances, the curse of dimensionality, or simply to save time

  8. Physical Abuse is Associated with HIV-related Drug Risk

    Those who have experienced abuse may be prone to engaging in risky sexual behavior and risky drug use. The relationship between sexual abuse and risky behavior has been well established in the literature, but the association between physical abuse and risky drug use has been equivocal. We hypothesize that the experience of PTSD symptoms following physical abuse leads to risky drug use. Therefore, we examined the associations among physical abuse history, PTSD symptoms, and HIV-related drug ri...

    Sleep facilitates declarative memory processing. However, we know little about whether sleep plays a role in the processing of a fundamental feature of declarative memory, relational memory - the flexible representation of items not directly learned prior to sleep. Thirty-one healthy participants first learned at 12 pm two sets of face-object photograph pairs (direct associative memory), in which the objects in each pair were common to both lists, but paired with two different faces. Participants either were given approximately 90 min to have a NREM-only daytime nap (n=14) or an equivalent waking period (n=17). At 4:30 pm, participants who napped demonstrated significantly better retention of direct associative memory, as well as better performance on a surprise task assessing their relational memory, in which participants had to associate the two faces previously paired with the same object during learning. Particularly noteworthy, relational memory performance was correlated with the amount of NREM sleep during the nap, with only slow-wave sleep predicting relational memory performance. Sleep stage data did not correlate with direct associative memory retention. These results suggest an active role for sleep in facilitating multiple processes that are not limited to the mere strengthening of rote memories, but also the binding of items that were not directly learned together, reorganizing them for flexible use at a later time.

    In practice, family-based design has been widely used in disease-gene association analysis. The major advantage of such design is that it is not subject to spurious association due to population structure such as population stratification (PS) and admixture. A disadvantage is that parental genotypes are hard to obtain if the disease is late onset for which a discordant-relative-pair design is useful. Designs of such kind include full-sib-pair, half-sib-pair, first-cousin-pair, and so on. The closer the relatedness of the pair, the less possible that they are subject to population stratification. On the other hand, the association test using close relative-pairs may be less powerful due to over-matching. Trade-off between these two factors (population structure and over-matching) is the major concern of this study. Some tests, namely McNemar's test, matched Cochran-Armitage trend tests (CATTs), matched maximum efficient robust test (MERT), and Bhapkar's test, are used for testing disease-gene association based on relative-pair designs. These tests are shown to be valid in the presence of PS but not admixture. Numerical studies show that the McNemar's test, additive CATT, MERT, and Bhapkar's test are robust in power, but none of them is uniformly more powerful than the others. In most simulations, the power of any of the tests increases as the pair is more distant. The proposed methods are applied to two real examples.

    Building on well-established findings of age-related decline in associative memory, we examined whether the magnitude of age differences depends on the types of associations that are formed. Specifically, because of predominant age-related changes in the hippocampus, we expected to find larger age differences in recognition of between-domain than within-domain associations. Twenty younger and 20 older healthy adults were given two associative recognition tests, using face-name and word-word pairs, that were matched for difficulty level. As hypothesized, a three-way interaction indicated that, relative to item recognition, age differences in associative recognition were greater for between-domain face-name associations than for within-domain word-word associations. This dissociation is consistent with the idea that the hippocampus plays a prominent role in binding information received from distal neocortical regions. The discussion focuses on the roles of recollection and familiarity in supporting associative memory as well as implications for the remediation of age-related memory decline.

    Thermal batteries can experience thermal runaway under certain usage conditions. This can lead to safety issues for personnel and cause damage to associated test equipment if the battery thermally self destructs. This report discusses a number of thermal and design related issues that can lead to catastrophic destruction of thermal batteries under certain conditions. Contributing factors are identified and mitigating actions are presented to minimize or prevent undesirable thermal runaway.

    Park, Hyojung; Reber, Bryan H

    2010-01-01

    This study explored health organizations' public relations efforts to frame health issues through their press releases. Content analysis of 316 press releases from three health organizations-the American Heart Association, the American Cancer Society, and the American Diabetes Association-revealed that they used the medical research frame most frequently and emphasized societal responsibility for health issues. There were differences, however, among the organizations regarding the main frames and health issues: the American Diabetes Association was more likely to focus on the issues related to social support and education, while the American Heart Association and the American Cancer Society were more likely to address medical research and scientific news. To demonstrate their initiatives for public health, all the organizations employed the social support/educational frame most frequently. Researchers and medical doctors frequently were quoted as trusted sources in the releases.

  18. The relational luring effect: Retrieval of relational information during associative recognition.

    2017-05-01

    Here we argue that semantic relations (e.g., works in: nurse-hospital) have abstract independent representations in long-term memory (LTM) and that the same representation is accessed by all exemplars of a specific relation. We present evidence from 2 associative recognition experiments that uncovered a novel relational luring effect (RLE) in recognition memory. Participants studied word pairs, and then discriminated between intact (old) pairs and recombined lures. In the first experiment participants responded more slowly to lures that were relationally similar (table-cloth) to studied pairs (floor-carpet), in contrast to relationally dissimilar lures (pipe-water). Experiment 2 extended the RLE by showing a continuous effect of relational lure strength on recognition times (RTs), false alarms, and hits. It used a continuous pair recognition task, where each recombined lure or target could be preceded by 0, 1, 2, 3 or 4 different exemplars of the same relation. RTs and false alarms increased linearly with the number of different previously seen relationally similar pairs. Moreover, more typical exemplars of a given relation lead to a stronger RLE. Finally, hits for intact pairs also rose with the number of previously studied different relational instances. These results suggest that semantic relations exist as independent representations in LTM and that during associative recognition these representations can be a spurious source of familiarity. We discuss the implications of the RLE for current models of semantic and episodic memory, unitization in associative recognition, analogical reasoning and retrieval, as well as constructive memory research.

    Basketball is a popular sport involving significant body contact, which may frequently result in ocular trauma. The aim of this study was to evaluate the characteristics and visual outcomes of retinal detachment associated with basketball-related injury. Retrospective, interventional case series. We reviewed the course of patients who sustained traumatic retinal detachment from basketball-related ocular trauma between 2003 and 2015. Thirteen patients were evaluated for basketball-related traumatic retinal detachment. Twelve (92%) were male and 1 (8%) female, with an average age of 18.2 years. The majority (9 of 13, 70%) of patients had moderate-to-high myopia, and none were using protective eyewear when they sustained the eye trauma. Rhegmatogenous retinal detachment was observed in all eyes. The preoperative mean visual acuity was 20/625 (range, hand motions to 20/20). Initial surgery using scleral buckling alone was performed in most (8 of 13, 62%) of the patients. Retinal reattachment was achieved in 10 (76%) eyes after the first operation and in 12 (92%) at the end of the intervention. The mean follow-up was 3.9 years (range, 4 months to 12 years). The visual acuity during last follow-up was 20/231 (range, light perception to 20/20). In the multivariable analysis, initial visual acuity was an independent factor affecting the final visual outcome (P = .006). Retinal detachment associated with basketball-related injury may cause severe visual loss. In the current study, all retinal detachments were of rhegmatogenous type and commonly occurred in young individuals with myopia. Initial visual acuity was associated with the prognosis. Risk awareness for early detection and intervention are important in these traumas. Copyright © 2017 Elsevier Inc. All rights reserved.

    Abstract The aim of this study was to determine the association of periodontitis with lifestyle-related comorbidities (LCs) using data in the Korean National Health Insurance Cohort Database from 2002 to 2013. This was a retrospective study involving a large national cohort with patient samples (representing 2% of the total Korean population) stratified on the basis of sociodemographic information. Using this precisely extracted database, the correlations between LCs (cerebral infarction, angina pectoris, myocardial infarction, hypertension, diabetes mellitus, rheumatoid arthritis, erectile dysfunction, osteoporosis, and obesity) and periodontitis were investigated while adjusting for confounding bias. Univariate and multiple logistic regression analyses were used to evaluate differences in variable factors. Among a total of 1,025,340 samples, 321,103 (31.3%) cases were diagnosed with periodontitis. Statistically significant associations were found between all LCs except myocardial infarction and periodontitis (P Periodontitis is significantly and positively correlated with LCs (except for myocardial infarction) after adjusting for confounding bias. In particular, lifestyle-related diseases, erectile dysfunction, and osteoporosis seem to be intimately related to periodontitis. PMID:26376407

    Full Text Available Abstract Objective To assess factors associated with drug-related harms related to policing among injection drug users (IDUs in Tijuana, Mexico. Methods IDUs who were over 18 years old and had injected drugs within the last six months were recruited via respondent-driven sampling and underwent questionnaires and testing for HIV (human immunodeficiency virus, syphilis and TB (tuberculosis. Random effects logistic regression was used to simultaneously model factors associated with five drug-related harms related to policing practices in the prior six months (i.e., police led them to rush injections; affected where they bought drugs; affected locations where they used drugs; feared that police will interfere with their drug use; receptive syringe sharing. Results Of 727 IDUs, 85% were male; median age was 38 years. Within the last 6 months, 231 (32% of IDUs reported that police had led them to rush injections, affected where they bought or used drugs or were very afraid police would interfere with their drug use, or shared syringes. Factors independently associated with drug-related harms related to policing within the last six months included: recent arrest, homelessness, higher frequencies of drug injection, use of methamphetamine, using the local needle exchange program and perceiving a decrease in the purity of at least one drug. Conclusions IDUs who experienced drug-related harms related to policing were those who were most affected by other micro and macro influences in the physical risk environment. Police education programs are needed to ensure that policing practices do not exacerbate risky behaviors or discourage protective behaviors such as needle exchange program use, which undermines the right to health for people who inject drugs.

    Acute viral hepatitis resulting due to hepatitis E viral infection (AVH-E) is often serious in pregnancy and could result in acute liver failure (ALF). The role of monocytes and macrophages (mono-macs) in the pathogenesis of AVH-E and development of ALF-E in pregnancy is unclear. We investigated the functions of mono-macs in pregnant (P), AVH-E (n = 44), ALF-E (n = 12), healthy controls (HC; n = 20) and compared with nonpregnant (NP) AVH-E (n = 10), ALF-E (n = 5), and HC (n = 10). We also recruited non-hepatitis E virus-related pregnant (P), ALF-NE (n = 5) and non-pregnant (NP), ALF-NE (n = 12) patients with ALF. Mono-macs, dendritic cell (DC) phenotypes, and Toll-like receptor (TLR) expressions were studied by flow cytometry and reverse-transcriptase polymerase chain reaction. Mono-macs functionality was determined by analyzing their phagocytic activity and reactive oxygen species (ROS) generation by using flow cytometry. Frequency of mono-macs and DCs was increased during HEV infection compared to HC (P pregnant ALF-E patients compared to AVH-E(P). Reduced TLR3 and TLR7 expression and TLR downstream-signaling molecules in pregnant ALF-E patients suggests inadequate triggers for the innate immune responses contributing to development and severity of ALF-E. Studies using TLR agonists to activate mono-macs may be of use and in vitro studies should be undertaken using patient samples. © 2015 by the American Association for the Study of Liver Diseases.

  7. Denture-Related Stomatitis Is Associated with Endothelial Dysfunction

    Full Text Available Oral inflammation, such as periodontitis, can lead to endothelial dysfunction, accelerated atherosclerosis, and vascular dysfunction. The relationship between vascular dysfunction and other common forms of oral infections such as denture-related stomatitis (DRS is unknown. Similar risk factors predispose to both conditions including smoking, diabetes, age, and obesity. Accordingly, we aimed to investigate endothelial function and major vascular disease risk factors in 44 consecutive patients with dentures with clinical and microbiological features of DRS (n=20 and without DRS (n=24. While there was a tendency for higher occurrence of diabetes and smoking, groups did not differ significantly in respect to major vascular disease risk factors. Groups did not differ in main ambulatory blood pressure, total cholesterol, or even CRP. Importantly, flow mediated dilatation (FMD was significantly lower in DRS than in non-DRS subjects, while nitroglycerin induced vasorelaxation (NMD or intima-media thickness (IMT was similar. Interestingly, while triglyceride levels were normal in both groups, they were higher in DRS subjects, although they did not correlate with either FMD or NMD. Conclusions. Denture related stomatitis is associated with endothelial dysfunction in elderly patients with dentures. This is in part related to the fact that diabetes and smoking increase risk of both DRS and cardiovascular disease.

  8. Risks associated with melamine and related triazine contamination of food.

    Baynes, Re; Riviere, Je

    2010-01-01

    Recent adulteration of milk products with melamine (ME) in several countries caused adverse health effects and even deaths in infants. Earlier, in 2007, contamination of pet food with ME and its related contaminants was associated with many clinical cases of canine and feline nephrotoxicity, and in some cases mortality. ME is a triazine compound that is often detected with other triazine analogs such as cyanuric acid. As is the custom in some livestock operations, the contaminated pet food was mixed with feed intended for the swine and poultry industry. This practice has raised several questions as to whether ME and its related triazines would adversely affect the health of these food animals, and whether meat products derived from swine and poultry could contain high-enough levels of these contaminants to warrant public health concern. Data for this review article were obtained from recent research efforts in our laboratory, peer-reviewed publications cited in PubMed, and information available at USDA, US FDA, and WHO websites. The primary issues discussed are related to (1) the chemistry and interactions between ME and its triazine analogs; (2) reported animal and human exposures with possible pathways through which ME can enter the human food chain; (3) mammalian toxicology; (4) comparative pharmacokinetics (PK) and modeling strategies used to predict residue levels; and (5) emerging issues and management strategies.

    Both solar and non-solar exposures associated with occupation and work tasks have been reported as skin carcinogens. In the UK, there are well-established surveillance schemes providing relevant information, including when exposures took place, occupation, location of work and dates of symptom onset and diagnosis. To add to the evidence on work-related skin neoplasia, including causal agents, geographical exposure and time lag between exposure and diagnosis. This study investigated incident case reports of occupational skin disease originating from clinical specialists in dermatology reporting to a UK-wide surveillance scheme (EPIDERM) by analysing case reports of skin neoplasia from 1996 to 2012 in terms of diagnosis, employment, suspected causal agent and symptom onset. The suspected causal agent was 'sun/sunlight/ultraviolet light' in 99% of the reported work-related skin neoplasia cases. Most cases reported (91%) were in males, and the majority (62%) were aged over 65 at the time of reporting. More detailed information on exposure was available for 42% of the cases, with the median time from exposure to symptom onset ranging from 44 (melanoma) to 57 (squamous cell carcinoma) years. Irrespective of diagnostic category, the median duration of exposure to 'sun/sunlight/ultraviolet light' appeared longer where exposures occurred in the UK (range 39-51 years) rather than outside the UK (range 2.5-6.5 years). It is important to provide effective information about skin protection to workers exposed to solar radiation, especially to outdoor workers based outside the UK. © The Author 2014.

  10. Medical adhesive-related skin injuries associated with vascular access.

    Hitchcock, Jan; Savine, Louise

    2017-04-27

    Establishing vascular access and preventing infection, both at insertion and during ongoing care is generally the top priority; the maintenance of optimal skin integrity is often a distant secondary consideration. Skin can react to different types of dressings or adhesives, or problems can arise relating to the securement of lines or the development of sensitivities to cleaning solutions. Clearly, these scenarios are not limited to the securement of vascular access devices; however, a patient with a long-term vascular access device may not have other options for vascular access, which makes this a very important and yet largely unrecognised area. A review of the limited literature that existed up to March 2015 showed it was typically concerned with skin tears connected with dressings and removal, and contact irritant dermatitis. The tissue viability team and vascular access team reviewed the current products associated with a typical vascular access dressing to ensure it was fit for purpose and where at all possible had good scientific literature for validation. The team worked proactively to recognise those patients at risk with the early identification of potential medical adhesive-related skin injuries (MARSI). To facilitate this an algorithm was developed that offers a step-by-step approach, clearly outlining what to do to prevent MARSI and its treatment should it develop. These reactions can result from other factors than the dressing alone, and an increase in these kinds of skin reaction in patients who are on chemotherapy regimens is being explored further. Through the implementation of an algorithm, education for both staff and patients and collaborative working between vascular access and tissue viability teams, a reduction in these phenomena has been seen despite an increasing number of at-risk patients.

  11. Dissecting auditory verbal hallucinations into two components: audibility (Gedankenlautwerden) and alienation (thought insertion).

    Science.gov (United States)

    Sommer, Iris E; Selten, Jean-Paul; Diederen, Kelly M; Blom, Jan Dirk

    2010-01-01

    This study proposes a theoretical framework which dissects auditory verbal hallucinations (AVH) into 2 essential components: audibility and alienation. Audibility, the perceptual aspect of AVH, may result from a disinhibition of the auditory cortex in response to self-generated speech. In isolation, this aspect leads to audible thoughts: Gedankenlautwerden. The second component is alienation, which is the failure to recognize the content of AVH as self-generated. This failure may be related to the fact that cerebral activity associated with AVH is predominantly present in the speech production area of the right hemisphere. Since normal inner speech is derived from the left speech area, an aberrant source may lead to confusion about the origin of the language fragments. When alienation is not accompanied by audibility, it will result in the experience of thought insertion. The 2 hypothesized components are illustrated using case vignettes. Copyright 2010 S.

    IgG4-positive (+) plasma cells have been reported in both Riedel's thyroiditis (RT) and Hashimoto's thyroiditis (HT). These cells are the hallmark of IgG4-related disease (IgG4-RD). We sought to determine whether RT is part of IgG4-RD spectrum. This was a case-control study performed at a tertiary medical centre. We included RT cases from the period 1958 to 2008 that had sufficient paraffin-embedded tissue for IgG4 immunostaining. Controls were patients with HT, age and gender matched, with similar pathology criteria. The main outcome measures were the intensity of the IgG4 staining and the clinical and histological correlates with IgG4-RD. Six pairs of RT and HT were analysed. The mean age was 44·7 years. In both groups, 5/6 cases had positive IgG4 staining. The mean number of IgG4 + cells/ HPF, normalized to the degree of inflammation, was 3·2 ± 3·0 SD (RT) vs 0·9 ± 0·7 (HT), P = 0·15, for fibrotic areas and 2·1 ± 2·3 SD vs 1·0 ± 0·8 (P = 0·39) for areas with lymphoid aggregates. We found the number of IgG4 +  cells in RT to be inversely correlated with the duration of disease (P = 0·046). Three RT cases had associated comorbidities from the IgG4-RD spectrum while none of the HT cases had such conditions. Riedel's thyroiditis is a component of IgG4-RD with the density of the IgG4 +  lymphocytic infiltrate being time dependent. In this small study, we did not identify differences in IgG4 infiltration between RT and HT, minimizing the utility of this marker in RT diagnosis. © 2016 John Wiley & Sons Ltd.

    Science.gov (United States)

    Introduction: In effect estimates of city-specific PM2.5-mortality associations across United States (US), there exists a substantial amount of spatial heterogeneity. Some of this heterogeneity may be due to mass distribution of PM; areas where PM2.5 is likely to be dominated by large size fractions (above 1 micron; e.g., the contribution of windblown dust), may have a weaker association with mortality. Methods: Log rate ratios (betas) for the PM2.5-mortality association—derived from a model adjusting for time, an interaction with age-group, day of week, and natural splines of current temperature, current dew point, and unconstrained temperature at lags 1, 2, and 3, for 313 core-based statistical areas (CBSA) and their metropolitan divisions (MD) over 1999-2005—were used as the outcome. Using inverse variance weighted linear regression, we examined change in log rate ratios in association with PM10-PM2.5 correlation as a marker of windblown dust/higher PM size fraction; linearity of associations was assessed in models using splines with knots at quintile values. Results: Weighted mean PM2.5 association (0.96 percent increase in total non-accidental mortality for a 10 ug/m3 increment in PM2.5) increased by 0.34 (95% confidence interval: 0.20, 0.48) per interquartile change (0.25) in the PM10-PM2.5 correlation, and explained approximately 8% of the observed heterogeneity; the association was linear based on spline analysis. Conclusions: Preliminary results pro

    Full Text Available Type 1 diabetes (T1D increases risk of the development of microvascular complications and cardiovascular disease (CVD. Dyslipidemia is a common risk factor in the pathogenesis of both CVD and diabetic nephropathy (DN, with CVD identified as the primary cause of death in patients with DN. In light of this commonality, we assessed single nucleotide polymorphisms (SNPs in thirty-seven key genetic loci previously associated with dyslipidemia in a T1D cohort using a case-control design. SNPs (n = 53 were genotyped using Sequenom in 1467 individuals with T1D (718 cases with proteinuric nephropathy and 749 controls without nephropathy i.e. normal albumin excretion. Cases and controls were white and recruited from the UK and Ireland. Association analyses were performed using PLINK to compare allele frequencies in cases and controls. In a sensitivity analysis, samples from control individuals with reduced renal function (estimated glomerular filtration rate<60 ml/min/1.73 m(2 were excluded. Correction for multiple testing was performed by permutation testing. A total of 1394 samples passed quality control filters. Following regression analysis adjusted by collection center, gender, duration of diabetes, and average HbA1c, two SNPs were significantly associated with DN. rs4420638 in the APOC1 region (odds ratio [OR] = 1.51; confidence intervals [CI]: 1.19-1.91; P = 0.001 and rs1532624 in CETP (OR = 0.82; CI: 0.69-0.99; P = 0.034; rs4420638 was also significantly associated in a sensitivity analysis (P = 0.016 together with rs7679 (P = 0.027. However, no association was significant following correction for multiple testing. Subgroup analysis of end-stage renal disease status failed to reveal any association. Our results suggest common variants associated with dyslipidemia are not strongly associated with DN in T1D among white individuals. Our findings, cannot entirely exclude these key genes which are central to the process of dyslipidemia, from

    Given the considerable prevalence of math anxiety, it is important to identify the factors contributing to it in order to improve mathematical learning. Research on math anxiety typically focusses on the effects of more complex arithmetic skills. Recent evidence, however, suggests that deficits in basic numerical processing and spatial skills also constitute potential risk factors of math anxiety. Given these observations, we determined whether math anxiety also depends on the quality of spatial-numerical associations. Behavioral evidence for a tight link between numerical and spatial representations is given by the SNARC (spatial-numerical association of response codes) effect, characterized by faster left-/right-sided responses for small/large digits respectively in binary classification tasks. We compared the strength of the SNARC effect between high and low math anxious individuals using the classical parity judgment task in addition to evaluating their spatial skills, arithmetic performance, working memory and inhibitory control. Greater math anxiety was significantly associated with stronger spatio-numerical interactions. This finding adds to the recent evidence supporting a link between math anxiety and basic numerical abilities and strengthens the idea that certain characteristics of low-level number processing such as stronger number-space associations constitute a potential risk factor of math anxiety.

    Grey relational clustering is used to minimise wire length during field programmable gate arrays (FPGA) placement and routing. The proposed Grey Relational Clustering Apply to Placement (GRAP) algorithm combines grey relational clustering and convex assigned placement for regular ICs method to construct a placement netlist, which was successfully used to solve the problem of minimising wire length in an FPGA placement. Upon calculating the grey relational grade, GRAP can rank the sequence and analyse the minimal distance in configuration logic blocks based on the grey relational sequence and combined connection-based approaches. The experimental results demonstrate that the GRAP effectively compares the Hibert, Z and Snake with bounding box (BB) cost function in the space-filling curve. The GRAP improved BB cost by 0.753%, 0.324% and 0.096% for the Hilbert, Z and Snake, respectively. This study also compares the critical path with the space-filling curve. The GRAP approach improved the critical path for Snake by 1.3% in the space-filling curve; however, the GRAP increased critical path wire by 1.38% and 0.03% over that of the Hilbert and Z of space-filling curve, respectively.

    Humans possess a basic need to belong and will join groups even when they provide no practical benefit. Paranoid symptoms imply a disruption of the processes involved in belonging and social trust. Past research suggests that joining social groups and incorporating those groups into one's identity (social identification) promotes positive self-views and better physical and mental health. However, no research has investigated whether social identity is associated with paranoia, nor the mechanisms by which this effect may emerge. Here, we examined the relationship between social identity and mental health (paranoia, auditory verbal hallucinations [AVHs], and depression), and tested the mediating role of self-esteem. In study 1, we analyzed data collected from 4319 UK residents as part of the NIHR CLAHRC NWC Household Health Survey. Study 2 comprised data collected from 1167 students attending a large UK university. The studies provided convergent evidence that social identification reduces symptoms of paranoia and depression by furnishing people with self-esteem. There was no consistent effect of social identification on AVHs. People developing mental health assessments, treatments, and policies are encouraged to consider the notion that joining and identifying with social groups may reduce people's risk of paranoia and depression. © The Author 2017.

    Several genetic alterations characteristic of leukemia and lymphoma have been detected in the blood of individuals without apparent hematological malignancies. We analyzed blood-derived sequence data from 2,728 individuals within The Cancer Genome Atlas, and discovered 77 blood-specific mutations in cancer-associated genes, the majority being associated with advanced age. Remarkably, 83% of these mutations were from 19 leukemia/lymphoma-associated genes, and nine were recurrently mutated (DNMT3A, TET2, JAK2, ASXL1, TP53, GNAS, PPM1D, BCORL1 and SF3B1). We identified 14 additional mutations in a very small fraction of blood cells, possibly representing the earliest stages of clonal expansion in hematopoietic stem cells. Comparison of these findings to mutations in hematological malignancies identified several recurrently mutated genes that may be disease initiators. Our analyses show that the blood cells of more than 2% of individuals (5–6% of people older than 70 years) contain mutations that may represent premalignant, initiating events that cause clonal hematopoietic expansion.

    Full Text Available Healthcare-associated infections (HAI are described in diverse settings. The main etiologic agents of HAI are bacteria (85% and fungi (13%. Some factors increase the risk for HAI, particularly the use of medical devices; patients with severe cuts, wounds, and burns; stays in the intensive care unit, surgery, and hospital reconstruction works. Several fungal HAI are caused by Candida spp., usually from an endogenous source; however, cross-transmission via the hands of healthcare workers or contaminated devices can occur. Although other medically important fungi, such as Blastomyces dermatitidis, Paracoccidioides brasiliensis, and Histoplasma capsulatum, have never been considered nosocomial pathogens, there are some factors that point out the pros and cons for this possibility. Among these fungi, H. capsulatum infection has been linked to different medical devices and surgery implants. The filamentous form of H. capsulatum may be present in hospital settings, as this fungus adapts to different types of climates and has great dispersion ability. Although conventional pathogen identification techniques have never identified H. capsulatum in the hospital environment, molecular biology procedures could be useful in this setting. More research on H. capsulatum as a HAI etiologic agent is needed, since it causes a severe and often fatal disease in immunocompromised patients.

  13. The differential effects of emotional salience on direct associative and relational memory during a nap.

    2016-12-01

    Relational memories are formed from shared components between directly learned memory associations, flexibly linking learned information to better inform future judgments. Sleep has been found to facilitate both direct associative and relational memories. However, the impact of incorporating emotionally salient information into learned material and the interaction of emotional salience and sleep in facilitating both types of memory is unknown. Participants encoded two sets of picture pairs, with either emotionally negative or neutral objects paired with neutral faces. The same objects were present in both sets, paired with two different faces across the sets. Baseline memory for these directly paired associates was tested immediately after encoding, followed by either a 90-min nap opportunity or wakefulness. Five hours after learning, a surprise test assessed relational memory, the indirect association between two faces paired with the same object during encoding, followed by a retest of direct associative memory. Overall, negative information was remembered better than neutral for directly learned pairs. A nap facilitated both preservation of direct associative memories and formation of relational memories, compared to remaining awake. Interestingly, however, this sleep benefit was observed specifically for neutral directly paired associates, while both neutral and negative relational associations benefitted from a nap. Finally, REM sleep played opposing roles in neutral direct and relational associative memory formation, with more REM sleep leading to forgetting of direct associations but promoting relational associations, suggesting that, while not benefitting memory consolidation for directly learned details, REM sleep may foster the memory reorganization needed for relational memory.

    Alcohol marketers have increasingly moved their advertising efforts into digital and social media venues. As a result, the purpose of this study is to investigate associations between students' use of social media, their exposure to alcohol marketing messages through social media, and their alcohol-related beliefs and behaviors. Public and private university students (N = 637) participated November and December 2011 and April 2012. College students completed online surveys to measure their exposure to social and online media generally, as well as their alcohol-related digital media use and alcohol use. Use of social media related to alcohol marketing predicted alcohol consumption and engaging in risky behaviors, whereas the use of social media more generally did not. Students' use of alcohol-related social media-marketing content associates with their problem drinking. Results have implications for alcohol abuse reduction efforts targeted at college students and suggest the importance of considering social, cultural, and cognitive factors in campaign planning and design.

  18. Subjective loudness and reality of auditory verbal hallucinations and activation of the inner speech processing network.

    Science.gov (United States)

    Vercammen, Ans; Knegtering, Henderikus; Bruggeman, Richard; Aleman, André

    2011-09-01

    One of the most influential cognitive models of auditory verbal hallucinations (AVH) suggests that a failure to adequately monitor the production of one's own inner speech leads to verbal thought being misidentified as an alien voice. However, it is unclear whether this theory can explain the phenomenological complexity of AVH. We aimed to assess whether subjective perceptual and experiential characteristics may be linked to neural activation in the inner speech processing network. Twenty-two patients with schizophrenia and AVH underwent a 3-T functional magnetic resonance imaging scan, while performing a metrical stress evaluation task, which has been shown to activate both inner speech production and perception regions. Regions of interest (ROIs) comprising the putative inner speech network were defined using the Anatomical Automatic Labeling system. Correlations were calculated between scores on the "loudness" and "reality" subscales of the Auditory Hallucination Rating Scale (AHRS) and activation in these ROIs. Second, the AHRS subscales, and general AVH severity, indexed by the Positive and Negative Syndrome Scale, were correlated with a language lateralization index. Louder AVH were associated with reduced task-related activity in bilateral angular gyrus, anterior cingulate gyrus, left inferior frontal gyrus, left insula, and left temporal cortex. This could potentially be due to a competition for shared neural resources. Reality on the other hand was found to be associated with reduced language lateralization. Strong activation of the inner speech processing network may contribute to the subjective loudness of AVH. However, a relatively increased contribution from right hemisphere language areas may be responsible for the more complex experiential characteristics, such as the nonself source or how real AVH are.

  19. Subjective relative deprivation is associated with poorer physical and mental health.

    2015-12-01

    Substantial epidemiological evidence has shown that income inequality and objective measures of relative deprivation are associated with poorer health outcomes. However, surprisingly little research has examined whether subjective feelings of relative deprivation are similarly linked with poorer health outcomes. The relative deprivation hypothesis suggests that inequality affects health at the individual level through negative consequences of social comparison. We directly examined the relationship between subjective feelings of personal relative deprivation and self-reported physical and mental health in a diverse community sample (n = 328). Results demonstrated that subjective feelings of personal relative deprivation are associated with significantly poorer physical and mental health. These relationships held even when accounting for covariates that have been previously associated with both relative deprivation and health. These results further support the link between relative deprivation and health outcomes and suggest that addressing root causes of relative deprivation may lead to greater individual health.

    Evidence is accumulating that childhood trauma might be associated with higher severity of positive symptoms in patients with psychosis and higher incidence of psychotic experiences in non-clinical populations. However, it remains unknown whether the history of childhood trauma might be associated with particular types of auditory verbal hallucinations (AVH). We assessed childhood trauma using the Early Trauma Inventory Self-Report - Short Form (ETISR-SF) in 94 first-episode schizophrenia (FES) patients. Lifetime psychopathology was evaluated using the Operational Criteria for Psychotic Illness (OPCRIT) checklist, while symptoms on the day of assessment were examined using the Positive and Negative Syndrome Scale (PANSS). Based on ETISR-SF, patients were divided into those with and without the history of childhood trauma: FES(+) and FES(-) patients. FES(+) patients had significantly higher total number of AVH types and Schneiderian first-rank AVH as well as significantly higher PANSS P3 item score (hallucinatory behavior) in comparison with FES(-) patients. They experienced significantly more frequently third person AVH and abusive/accusatory/persecutory voices. These differences remained significant after controlling for education, PANSS depression factor score and chlorpromazine equivalent. Linear regression analysis revealed that the total number of AVH types was predicted by sexual abuse score after controlling for above mentioned confounders. This effect was significant only in females. Our results indicate that the history of childhood trauma, especially sexual abuse, is associated with higher number AVH in females but not in males. Third person AVH and abusive/accusatory/persecutory voices, representing Schneiderian first-rank symptoms, might be particularly related to childhood traumatic events. Copyright © 2015 Elsevier Inc.

    This short-term longitudinal study examined the association between relational and physical victimization and subsequent depressive symptoms together with the roles of social cognitive processes (i.e., relational interdependence) and gender in this association. A total of 580 Japanese adolescents in the seventh and eighth grades (52 % girls; age range 12-14) participated in this study across an academic year. Results of structural equation modeling demonstrated that relational and physical victimization, which was assessed via self- and teacher- reports, was concurrently associated with greater depressive symptoms, regardless of the gender of the youth and the level of relational interdependence. Furthermore, after controlling for the stability and co-occurrence between each construct, relational victimization (not physical victimization) was predictive of elevated depressive symptoms only for boys who exhibited relatively higher relational interdependence. The findings are discussed from developmental, gender, and cultural perspectives.

    Several cognitive-affective constructs, including pain catastrophizing and pain-related anxiety, have been implicated in the onset and progression of chronic pain, and both constructs have been identified as key targets for multidisciplinary pain treatment. Both neuroticism and depression have been linked to these constructs (and to each other), but how each may contribute to the pain experience is unknown. This study tested associations between neuroticism, depression, and indices of catastrophizing and pain-related anxiety among persons seeking treatment for chronic non-malignant pain. We hypothesized, as a higher-order personality trait, neuroticism would remain uniquely associated with both pain catastrophizing and pain-related anxiety, even after accounting for current symptoms of depression. A retrospective study design assessed depression (as measured by the Centers for Epidemiologic Studies-Depression scale), neuroticism (measured with the Neuroticism-Extraversion-Openness Personality Inventory), the Pain Catastrophizing Scale, and the Pain Anxiety Symptom Score in a consecutive series of patients (n=595) admitted to a 3-week outpatient pain treatment program from March 2009 through January 2011. Hierarchical regression indicated that neuroticism was independently associated with greater pain catastrophizing and pain-related anxiety, above-and-beyond the contributions of sociodemographic characteristics, pain severity, and depression. A depression by neuroticism interaction was not observed, suggesting that associations between neuroticism and cognitive-affective pain constructs remained stable across varying levels of current depression. These findings represent an early but important step towards the clarification of complex associations between trait neuroticism, current depression, and tendencies toward catastrophic and anxiety-provoking appraisals of pain among persons seeking treatment for chronic pain.

    When compositional differences between age groups are controlled, the bivariate, curvilinear pattern of age differences in voluntary association memberships is replaced by one in which peak membership levels occur in late middle age and remain relatively stable thereafter. We sought to determine if this adjusted pattern persists when widespread memberships in two types of associations are removed: (1) church-related organizations, in which membership increases with age but may be confounded with church membership per se; and (2) labor unions, in which membership is also widespread but may not be "voluntary." Total memberships in 14 types of associations were examined using aggregated data from 12 national surveys conducted between 1974 and 1994. The familiar curvilinear relationship at the bivariate level appears, but in the multivariate analysis, membership levels rise from ages 18-24 through 55-59 and persist close to that level through ages 85 and older. The results reaffirm that age differences in voluntary association affiliations are due to age-based compositional differences; they also show, however, that the pattern observed with controls is neither driven by membership in church-related "associations" nor altered when membership in labor unions is excluded.

    Experimental evidence has suggested that vitamin D may be protective against tobacco-related cancers through the inhibition of the formation of tumors induced by tobacco carcinogens. To our knowledge, only one previous epidemiologic study investigated the association between vitamin D status and tobacco-related cancer risk, and no study has focused on vitamin D-related gene polymorphisms. Our objective was to prospectively study the association between plasma 25-hydroxyvitamin D [25(OH)D] concentrations, vitamin D-related gene polymorphisms, and risk of tobacco-related cancers. A total of 209 tobacco-related cancers were diagnosed within the SU.VI.MAX (Supplémentation en vitamines et minéraux antioxydants) cohort (1994-2007) and were matched with 418 controls as part of a nested case-control study. Tobacco-related cancers (i.e., cancers for which tobacco is one of the risk factors) included several sites in the respiratory, digestive, reproductive, and urinary systems. Total plasma 25(OH)D was assessed with the use of an electrochemoluminescent assay. Polymorphisms were determined with the use of a TaqMan assay. Conditional logistic regression models were computed. A 25(OH)D concentration ≥30 ng/mL was associated with reduced risk of tobacco-related cancers (OR for ≥30 compared with cancers [OR for homozygous mutant type (MT) compared with wild type (WT): 1.87; 95% CI: 1.08, 3.23; P-trend = 0.02; OR for heterozygous type (HT) plus MT compared with WT: 1.60; 95% CI: 1.07, 2.38; P = 0.02]. In this prospective study, high vitamin D status [25(OH)D concentration ≥30 ng/mL] was associated with decreased risk of tobacco-related cancers, especially in smokers. These results, which are supported by mechanistic plausibility, suggest that vitamin D may contribute to the prevention of tobacco-induced cancers in smokers and deserve additional investigation.

    Understanding factors associated with alcohol-related consequences is an important area of research. Emotional functioning has been associated with alcohol-related consequences but there is less research examining a comprehensive underlying model of emotional regulation. The Difficulties in Emotion Regulation Scale (DERS) is a recent measure developed to assess six facets of emotion regulation difficulties that contribute to overall emotional functioning. The current study examines associations between these six facets of emotion regulation difficulties and problematic alcohol use. Participants (n = 1758 college students) were recruited as part of a larger study and were asked to complete online questionnaires assessing demographics, alcohol use and problems, and emotion regulation difficulties. Negative binomial hurdle models for alcohol use and alcohol-related consequences were estimated. Impulse control difficulties were positively related to the number of drinks consumed during the week among active drinkers. Non-acceptance of emotional responses, impulse control difficulties, lack of emotional clarity, and difficulties engaging in goal-directed behavior were all positively associated with number of consequences endorsed. Difficulty engaging in goal-directed behavior was also positively associated with the likelihood of experiencing any alcohol-related consequences. The findings support previous research indicating that emotion-regulation difficulties are broadly associated with alcohol-related consequences. Results suggest exposure and/or mindfulness based prevention/interventions with emotion focused psychoeducation may offer one path to reducing alcohol-related consequences among college students.

    Full Text Available OBJECTIVE: Anxiety symptoms are common in chronic pain patients. High levels of anxiety are associated with increased pain experience and disability. Proneness to anxiety has a large interindividual variation. The aim of the study was to determine whether the anxiety-related temperament trait Harm Avoidance (HA, is associated with pain-related anxiety. METHODS: One hundred chronic pain patients in a multidisciplinary pain clinic participated in the study. The patients were assessed using the HA scale of the Temperament and Character Inventory (TCI of Cloninger and Pain Anxiety Symptoms Scale-20 (PASS-20. Both the HA total score and the four subscales of HA were analyzed. Current pain intensity was measured using the Visual Analogue Scale (VAS. The Beck Depression Inventory (BDI was used to control for the influence of depression on the personality measurement. RESULTS: The HA total score was associated with PASS-20, but the association became non-significant after controlling for depression. The HA4 Fatigability subscale was associated with the PASS scales. Depression did not influence this association. Pain intensity was not correlated with HA or the PASS scales. However, the association between HA4 Fatigability and PASS was influenced by pain intensity. Higher pain intensity was associated with stronger association between the scales. CONCLUSION: Harm Avoidance, representing temperament and trait-related anxiety, has relevance in pain-related anxiety. Assessing personality and temperament may deepen the clinician's understanding of the pain experience and behavior in chronic pain patients.

    Paired associates learning (PAL) has been widely used in aging-related research, suggesting an age-related decline in associative learning. However, there are several cognitive processes (attention, spatial and recognition memory, strategy, and associative learning) involved in PAL. It is unclear which component contributes to the decline in PAL performance associated with age effects. The present study determines whether age effects on associative learning are independent of other cognitive processes involved in PAL. Using a validated computerized cognitive program (CANTAB), we examined cognitive performance of associative learning, spatial and recognition memory, attention and strategy use in 184 Singaporean Chinese adults aged from 21 to 80 years old. Linear regression revealed significant age-related decline in associative learning, spatial and recognition memory, and the level of strategy use. This age-related decline in associative learning remains even after adjusting for attention, spatial and recognition memory, and strategy use. These results show that age effects on associative learning are independent of other cognitive processes involved in PAL.

    Heavy drinking students experience a myriad of alcohol-related negative consequences. Use of event-level data permits predictions to be made regarding (a) the likelihood of alcohol-related consequences occurring after specific drinking events, and (b) moderators of the association between intoxication and consequences. College students (N = 183, 64% female) completed four consecutive 7-day drinking diaries and turned them in weekly. The diaries yielded prospective event-level data on daily drinks, time spent drinking, and negative consequences related to each drinking event. Alcohol intoxication on a given day was significantly associated with increased levels of risk, although this association was moderated by average level of intoxication. Furthermore, self-control was associated with increased likelihood of negative consequences at all levels of intoxication, and self-regulation and impulsivity moderated the event-level association between daily intoxication and likelihood of negative consequences. Results suggest that self-regulation subsumes impulsivity and self-control. PMID:17563139

    Full Text Available Establishing associations between pieces of information is related to the medial temporal lobe (MTL. However, it remains unclear how emotions affect memory for associations and, consequently, MTL activity. Thus, this event-related fMRI study attempted to identify neural correlates of the influence of positive and negative emotions on associative memory. Twenty-five participants were instructed to memorize 90 pairs of standardized pictures during a scanned encoding phase. Each pair was composed of a scene and an unrelated object. Trials were neutral, positive, or negative as a function of the emotional valence of the scene. At the behavioral level, participants exhibited better memory retrieval for both emotional conditions relative to neutral trials. Within the right MTL, a functional dissociation was observed, with entorhinal activation elicited by emotional associations, posterior parahippocampal activation elicited by neutral associations, and hippocampal activation elicited by both emotional and neutral associations. In addition, emotional associations induced greater activation than neutral trials in the right amygdala. This fMRI study shows that emotions are associated with the performance improvement of associative memory, by enhancing activity in the right amygdala and the right entorhinal cortex. It also provides evidence for a rostrocaudal specialization within the MTL regarding the emotional valence of associations.

    The obesity epidemic is responsible for a substantial economic burden in developed countries and is a major risk factor for type 2 diabetes and cardiovascular disease. The disease is the result not only of several environmental risk factors, but also of genetic predisposition. To take advantage of recent advances in gene-mapping technology, we executed a genome-wide association scan to identify genetic variants associated with obesity-related quantitative traits in the genetically isolated population of Sardinia. Initial analysis suggested that several SNPs in the FTO and PFKP genes were associated with increased BMI, hip circumference, and weight. Within the FTO gene, rs9930506 showed the strongest association with BMI (p = 8.6 ×10− 7), hip circumference (p = 3.4 × 10− 8), and weight (p = 9.1 × 10− 7). In Sardinia, homozygotes for the rare “G” allele of this SNP (minor allele frequency = 0.46) were 1.3 BMI units heavier than homozygotes for the common “A” allele. Within the PFKP gene, rs6602024 showed very strong association with BMI (p = 4.9 × 10− 6). Homozygotes for the rare “A” allele of this SNP (minor allele frequency = 0.12) were 1.8 BMI units heavier than homozygotes for the common “G” allele. To replicate our findings, we genotyped these two SNPs in the GenNet study. In European Americans (N = 1,496) and in Hispanic Americans (N = 839), we replicated significant association between rs9930506 in the FTO gene and BMI (p-value for meta-analysis of European American and Hispanic American follow-up samples, p = 0.001), weight (p = 0.001), and hip circumference (p = 0.0005). We did not replicate association between rs6602024 and obesity-related traits in the GenNet sample, although we found that in European Americans, Hispanic Americans, and African Americans, homozygotes for the rare “A” allele were, on average, 1.0–3.0 BMI units heavier than homozygotes for the more common “G” allele. In summary, we have completed a whole

    Evaluations of "the prototypical nondrinker" and of "the prototypical regular drinker" have been demonstrated to hold associations with more harmful drinking behavior, yet the extent to which the relative evaluation of these prototypes is associated with drinking intention remains to be tested. To explore whether relatively unfavorable nondrinker prototypes are associated with increased drinking intention and whether this relationship is moderated by personality variables. Among a student sample (n = 543), alcohol-related sociability prototype measures were used to compute an index of the perceived sociability of regular drinkers relative to nondrinkers ("relative sociability prototypes"). Measures of drinking intention, conscientiousness, extraversion and sensation seeking impulsivity were also taken. Most students perceived the prototypical nondrinker unfavorably relative to the prototypical regular drinker (91%, n = 493). Simple slopes analyses indicated that extraversion moderated the strength of the relationship between relative sociability prototypes and drinking intention such that relatively negative evaluations of nondrinkers were only associated with increased intention to get drunk among more extraverted students. Prospective data and behavioral measures are needed to substantiate these findings, which suggest links between relative evaluations of nondrinkers, harmful drinking intention and personality traits. Evidence suggests that by challenging prejudicial beliefs concerning nondrinkers (as "unsociable") and by targeting more extraverted students, safer drinking plans might be encouraged.

    Parental monitoring and family relations are recognized as protective factors for youth alcohol use. The purpose of this study was to investigate perceived parental monitoring and family relations among subgroups of Mexican youths with different patterns of drinking behaviors and consequences. A latent profile analysis (LPA) identified profiles of drinking behavior in a cross-sectional survey of entering first year university students. Multinomial regression examined associations between parental monitoring, family relations and drinking profiles among 22,224 students. Both lower perceived parental monitoring and weaker perceived family relations were associated with heavier drinking profiles among males and females, but more strongly associated with female than male heavier drinking profiles. Being older, having parents with lower education, and not living with parents were also associated with lower parental monitoring and weaker family relations. There was a general trend of lower parental monitoring and weaker family relations as the profiles increased from Non/Infrequent-No Consequences to Excessive-Many Consequences Drinkers. Lower perceived parental monitoring and weaker perceived family relations were more strongly associated with drinking profiles among females than among males. Both the parental monitoring and family relations scales had similar associations with drinking profiles. Findings suggest that drinking norms and values may contribute to any protective influences of parental monitoring and family relations on Mexican youths' drinking. Research about changes in drinking norms, contextual factors, and youth-parent trust would inform the utility of parental monitoring or family relations as protective strategies against alcohol misuse among Mexican and Mexican American youths and also youths from other backgrounds.

    Two single-nucleotide polymorphisms (SNPs) on oxytocin-related genes, specifically the oxytocin receptor (OXTR) rs53576 and the CD38 rs3796863 variants, have been associated with alterations in prosocial behaviors. A cross-sectional study was conducted among undergraduate students (N = 476) to examine associations between the OXTR and CD38 polymorphisms and unsupportive social interactions and mood states. Results revealed no association between perceived levels of unsupportive social interactions and the OXTR polymorphism. However, A carriers of the CD38 polymorphism, a variant previously associated with elevated oxytocin, reported greater perceived peer unsupportive interactions compared to CC carriers. As expected, perceived unsupportive interactions from peers was associated with greater negative affect, which was moderated by the CD38 polymorphism. Specifically, this relation was stronger among CC carriers of the CD38 polymorphism (a variant thought to be linked to lower oxytocin). When examining whether the OXTR polymorphism moderated the relation between unsupportive social interactions from peers and negative affect there was a trend toward significance, however, this did not withstand multiple testing corrections. These findings are consistent with the perspective that a variant on an oxytocin polymorphism that may be tied to lower oxytocin is related to poor mood outcomes in association with negative social interactions. At the same time, having a genetic constitution presumed to be associated with higher oxytocin was related to increased perceptions of unsupportive social interactions. These seemingly paradoxical findings could be related to previous reports in which variants associated with prosocial behaviors were also tied to relatively more effective coping styles to deal with challenges.

    Young people's engagement in electronic gaming and Internet communication have caused concerns about potential harmful effects on their social relations, but the literature is inconclusive. The aim of this paper was to examine whether perceived problems with computer gaming and Internet communication are associated with young people's social relations. Cross-sectional questionnaire survey in 13 schools in the city of Aarhus, Denmark, in 2009. Response rate 89%, n = 2,100 students in grades 5, 7, and 9. Independent variables were perceived problems related to computer gaming and Internet use, respectively. Outcomes were measures of structural (number of days/week with friends, number of friends) and functional (confidence in others, being bullied, bullying others) dimensions of student's social relations. Perception of problems related to computer gaming were associated with almost all aspects of poor social relations among boys. Among girls, an association was only seen for bullying. For both boys and girls, perceived problems related to Internet use were associated with bullying only. Although the study is cross-sectional, the findings suggest that computer gaming and Internet use may be harmful to young people's social relations.

    Objectives. We examined whether workplace aggression was associated with self-rated health and work-related injury and illness among nurses in the Philippines. Methods. Our data came from a cross-sectional survey of nurses (n = 687) in the Philippines. We assessed the associations of self-reported physical assault and verbal abuse with self-rated health, work-related injury and illness, and missed workdays with Poisson regression. Control variables included demographic and work characteristics (e.g., hours worked, work setting, shift). Results. Verbal abuse was associated with poor general health (prevalence ratio [PR] = 1.94; 95% confidence interval [CI] = 1.09, 3.45). Both physical assault and verbal abuse were associated with work-related injury (PR = 1.48; 95% CI = 1.00, 2.20; PR = 1.72; 95% CI = 1.34, 2.23, respectively) and work-related illness (PR = 1.46; 95% CI = 0.99, 2.15; PR = 1.68; 95% CI = 1.32, 2.14, respectively) after demographic and work characteristics were accounted for in the model. In addition, physical assault was associated with missed workdays (PR = 1.56; 95% CI = 1.02, 2.33). Conclusions. Workplace aggression was associated with increased risks of poor general health and adverse work-related health outcomes among nurses in the Philippines. PMID:21088262

    Association rule analysis methods are important techniques applied to gene expression data for finding expression relationships between genes. However, previous methods implicitly assume that all genes have similar importance, or they ignore the individual importance of each gene. The relation intensity between any two items has never been taken into consideration. Therefore, we proposed a technique named REMMAR (RElational-based Multiple Minimum supports Association Rules) algorithm to tackle this problem. This method adjusts the minimum relation support (MRS) for each gene pair depending on the regulatory relation intensity to discover more important association rules with stronger biological meaning. In the actual case study of this research, REMMAR utilized the shortest distance between any two genes in the Saccharomyces cerevisiae gene regulatory network (GRN) as the relation intensity to discover the association rules from two S.cerevisiae gene expression datasets. Under experimental evaluation, REMMAR can generate more rules with stronger relation intensity, and filter out rules without biological meaning in the protein-protein interaction network (PPIN). Furthermore, the proposed method has a higher precision (100%) than the precision of reference Apriori method (87.5%) for the discovered rules use a literature survey. Therefore, the proposed REMMAR algorithm can discover stronger association rules in biological relationships dissimilated by traditional methods to assist biologists in complicated genetic exploration.

    Full Text Available Age-related macular degeneration (AMD is the most widely recognised cause of irreversible vision loss and previous studies have suggested that the advancement of wet AMD is influenced by both modifiable and non-modifiable elements. Single nucleotide polymorphism (SNPs and copy number of variations (CNVs have been associated with AMD in various populations, however the results are conflicting. Our aim is to determine the CNVs of Complement Factor H-Related genes among Malaysian subjects with wet AMD. 130 patients with wet AMD and 120 healthy controls were included in this research. DNA was extracted from all subjects and CNVs of CFH, CFHR1 and CFHR3 genes; determined using quantitative real-time PCR and were compared between the two groups. A consistent association was observed between CFH gene and wet AMD susceptibility (P < 0.05. The age-adjusted data suggests a possible increased risk of AMD disease (P < 0.05. No correlation was detected between CNVs and wet AMD for the remaining genes after we compared the frequencies of mean for that gene. An association was observed between CFH CNVs and wet AMD in the Malaysian population, however, strong evidence of a link with wet AMD was not found. Further investigative studies are needed using larger sample sizes to elucidate the role of CNVs in AMD pathogenesis.

    Older adults often experience associative memory impairments but can sometimes remember important information. The current experiments investigate potential age-related similarities and differences associate memory for gains and losses. Younger and older participants were presented with faces and associated dollar amounts, which indicated how much money the person "owed" the participant, and were later given a cued recall test for the dollar amount. Experiment 1 examined face-dollar amount pairs while Experiment 2 included negative dollar amounts to examine both gains and losses. While younger adults recalled more information relative to older adults, both groups were more accurate in recalling the correct value associated with high-value faces compared to lower-value faces and remembered gist-information about the values. However, negative values (losses) did not have a strong impact on recall among older adults versus younger adults, illustrating important associative memory differences between younger and older adults.

    Sleep problems among university students are common; however, the association between many sleep-related factors and sleep behaviors is still unclear. The purpose of this study is to examine different sleep behaviors and sleep-related factors influencing such behaviors in university students. A descriptive survey was conducted on 400 university students in Hong Kong. The instruments for data collection consisted of the Pittsburgh Sleep Quality Index (PSQI), a sleep hygiene practice questionnaire, demographic data, and other sleep-related factors. The results reveal that 57.5% of the 400 university students are poor sleepers. Sex, year of study, sleep hygiene practice, and perceived adequate sleep in the past month all demonstrate significant associations with poor sleepers. A high prevalence of sleep-related problems among college students is confirmed and associated factors are identified. Students should be encouraged to follow sleep hygiene practice, adequate time management for academic and social activities, and suitable stress-relieving measures.

    This study examined the relations between overt and relational aggression, social anxiety, loneliness, depressive symptoms, and alcohol and drug use in a sample of 287 undergraduate college students. Consistent with prior work, men reported engaging in more overt aggression than women. Contrary to our predictions, men also reported engaging in more relational aggression than women. Results also indicated that overt and relational aggression were positively associated with social anxiety, loneliness, depressive symptoms, alcohol use, and drug use for the overall sample. Hierarchical regression analyses showed positive relations between overt aggression and alcohol use for men and no relations between relational aggression and any psychosocial adjustment index. For women, overt aggression uniquely predicted social anxiety, loneliness, and depressive symptoms, whereas relational aggression uniquely predicted social anxiety, loneliness, depression, and alcohol and drug problems. Implications of these findings are discussed in terms of the role of peer aggression in students' psychosocial adjustment.

    All states in the U.S. prohibit alcohol-impaired driving but active law enforcement is necessary for effectively reducing this behavior. Sobriety checkpoints, saturation patrols, open container laws, and media campaigns related to enforcement efforts are all enforcement-related strategies for reducing alcohol-impaired driving. We conducted surveys of all state patrol agencies and a representative sample of local law enforcement agencies to assess their use of alcohol-impaired driving enforcement-related strategies and to determine the relationship between these enforcement-related strategies and self-reported alcohol-impaired driving behavior obtained from the Behavioral Risk Factor Surveillance System. We found that sobriety checkpoints, saturation patrols, and enforcement of open container laws were associated with a lower prevalence of alcohol-impaired driving but, more importantly, a combination of enforcement-related strategies was associated with a greater decrease in alcohol-impaired driving than any individual enforcement-related activity. In addition, alcohol-impaired driving enforcement-related strategies were associated with decreased alcohol-impaired driving above and beyond their association with decreased binge drinking. Results suggest law enforcement agencies should give greater priority to using a combination of strategies rather than relying on any one individual enforcement activity.

    Age-related macular degeneration is the leading cause of blindness in elderly individuals in developed countries. The etiology and pathophysiology of age-related macular degeneration have not been elucidated yet. Knowing that the main pathological change of age-related macular degeneration is formation of drusen containing about 40% of lipids, there have been attempts to find associations between age-related macular degeneration and genes controlling lipid metabolism. To determine the frequency of CYP2C19 (G681A) Rs4244285 and CYP1A2 (-163C>A) Rs762551 genotypes in patients with age-related macular degeneration. The study enrolled 150 patients with early age-related macular degeneration and 296 age- and gender-matched healthy controls. The genotyping of Rs4244285 and Rs762551 was carried out by using the real-time polymerase chain reaction method. The CYP1A2 (-163C>A) Rs762551 C/C genotype was more frequently detected in patients with age-related macular degeneration than in the control group (32.7% vs. 21.6%, p = 0.011) and was associated with an increased risk of developing early age-related macular degeneration (OR = 1.759, 95% CI: 1.133-2.729; p = 0.012). The CYP1A2 (-163C>A) Rs762551 C/A genotype was more frequently documented in the control group compared with patients with age-related macular degeneration (46.3% vs. 30.7%, p = 0.002) and was associated with a decreased risk of having age-related macular degeneration (OR = 0.580. 95% CI: 0.362-0.929, p = 0.023) in the co-dominant model. The study showed that the CYP1A2 (-163C>A) Rs762551 C/C genotype was associated with an increased risk of age-related macular degeneration.

    The Gene Ontology (GO) is a controlled vocabulary widely used for the annotation of gene products. GO is organized in three hierarchies for molecular functions, cellular components, and biological processes but no relations are provided among terms across hierarchies. The objective of this study is to investigate three non-lexical approaches to identifying such associative relations in GO and compare them among themselves and to lexical approaches. The three approaches are: computing similarity in a vector space model, statistical analysis of co-occurrence of GO terms in annotation databases, and association rule mining. Five annotation databases (FlyBase, the Human subset of GOA, MGI, SGD, and WormBase) are used in this study. A total of 7,665 associations were identified by at least one of the three non-lexical approaches. Of these, 12% were identified by more than one approach. While there are almost 6,000 lexical relations among GO terms, only 203 associations were identified by both non-lexical and lexical approaches. The associations identified in this study could serve as the starting point for adding associative relations across hierarchies to GO, but would require manual curation. The application to quality assurance of annotation databases is also discussed.

    The interaction between the somatosensory and motor cortices is understood; however, their functional relationship remains elusive. To elucidate the association between somatosensory and sensorimotor functions, this study investigated the correlation between somatosensory activities in response to paired-pulse stimulation and sensorimotor oscillations during self-paced finger movement in 18 healthy male subjects by using a magnetoencephalographic recording. The main finding was that stimulus-evoked somatosensory gating activities were significantly correlated with movement-related sensorimotor oscillatory responses. Specifically, the gating ratios of somatosensory N20m were related to the power changes of sensorimotor beta event-related desynchronization (ERD) (p=0.003) and event-related synchronization (ERS) (p=0.05). In conclusion, we confirmed that the inhibition of stimulus-evoked somatosensory responses is associated with the oscillatory characteristics of movement-related sensorimotor activities.

    Early life stress (ELS) is strongly associated with negative outcomes in adulthood, including reduced motivation and increased negative mood. The mechanisms mediating these relations, however, are poorly understood. We examined the relation between exposure to ELS and reward-related brain activity, which is known to predict motivation and mood, at age 26, in a sample followed since kindergarten with annual assessments. Using functional neuroimaging, we assayed individual differences in the activity of the ventral striatum (VS) during the processing of monetary rewards associated with a simple card-guessing task, in a sample of 72 male participants. We examined associations between a cumulative measure of ELS exposure and VS activity in adulthood. We found that greater levels of cumulative stress during childhood and adolescence predicted lower reward-related VS activity in adulthood. Extending this general developmental pattern, we found that exposure to stress early in development (between kindergarten and grade 3) was significantly associated with variability in adult VS activity. Our results provide an important demonstration that cumulative life stress, especially during this childhood period, is associated with blunted reward-related VS activity in adulthood. These differences suggest neurobiological pathways through which a history of ELS may contribute to reduced motivation and increased negative mood. © The Author (2015).

    Objective: To provide athletic trainers, health care professionals, and all those responsible for the care of athletes with clinical recommendations for preventing and managing sport-related dental and oral injuries. Background: Participation in competitive sports continues to grow at both the interscholastic and intercollegiate levels. Therefore, exposure to, and the incidence of athletic-related injury, including orofacial injury, will also likely increase. At the time of this writing, the leading governing agencies for interscholastic (National Federation of State High School Associations) and intercollegiate (National Collegiate Athletic Association) sports require only protective orofacial equipment (eg, mouthguards) for 5 and 4, respectively, of their sanctioned sports. Although orofacial injuries represent a small percentage of all sport-related injuries, the financial burden associated with these injuries (eg, tooth avulsion) can exceed $15 000 over an adult life. Therefore, effective management of sport-related dental injuries is critical to the long-term financial, physical, and emotional health of people who have experienced dental trauma. Recommendations: Based upon the current evidence regarding sport-related orofacial injury, we provide recommendations related to planning considerations, education, and mouthguard efficacy, material, fabrication, and care considerations. Additionally, suggested best practices for managing sport-related dental injury are also given for athletic trainers and other health care professionals. PMID:27875057

    Age-related macular degeneration is a multifactorial disease that can lead to vision impairment in older individuals. Although the etiology of age-related macular degeneration remains unknown, risk factors include age, ethnicity, smoking, hypertension, obesity, and genetic factors. Two main loci have been identified through genome-wide association studies, on chromosomes 1 and 10. Among the variants located at the 10q26 region, rs11200638, located at the HTRA1 gene promoter, has been associated with age-related macular degeneration in several populations and is considered the main polymorphism. We conducted a replication case-control study to analyze the frequency and participation of rs11200638 in the etiology of age-related macular degeneration in a sample of patients and controls from the State of São Paulo, Brazil, through polymerase chain reaction and enzymatic digestion. The frequency of the A allele was 57.60% in patients with age-related macular degeneration and 36.45% in controls (p value age-related macular degeneration group compared to the control group (p = 1.21 e-07 and 0.0357, respectively). No statistically significant results were observed after stratification in dry versus wet types or advanced versus non-advanced forms. To our knowledge, this is the first time the association between rs11200638 and overall age-related macular degeneration has been reported in South America.

    Little is known about the association between structural macular damage and self-reported visual function of people with glaucoma. To determine the association between vision-related quality of life among patients with primary open-angle glaucoma with structural macular retinal ganglion cell plus inner plexiform layer (RGC+IPL) loss identified by spectral-domain optical coherence tomography (SD-OCT) machine-generated deviation maps and thickness measurements. This cross-sectional prospective study was conducted from March 1, 2014, to March 30, 2015, at the Department of Ophthalmology at Columbia University Medical Center. The participants were 107 patients who were enrolled in the study and represented the entire range of glaucomatous damage. All 214 eyes of the 107 participants underwent 10-2 visual field tests and SD-OCT scans, and all participants completed the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25). They also received ophthalmologic examination, including medical history review, best-corrected visual acuity, slitlamp biomicroscopy, intraocular pressure measurement, gonioscopy, dilated ophthalmoscopy, and standard automated perimetry. Macular RGC+IPL loss was determined by diffuse or focal patterns on SD-OCT-generated deviation maps (probability map that compared patients with aged-matched normative database) and thickness measurements. Regression analyses to assess the association of NEI VFQ-25 scores (score range: 41.9-99.5; higher scores indicate better functioning) with patterns of RGC+IPL loss and with RGC+IPL thickness measurements. Of the 107 patients, 48 (45%) were men and the mean (SD) age was 65 (11) years. The self-reported race/ethnicity of participants consisted of 45 (46%) black, 47 (48%) white, and 6 (6%) "other" individuals. In the univariable analyses, patients with diffuse macular RGC+IPL loss had mean composite Rasch-calibrated NEI VFQ-25 scores that were 6.15 points lower than the scores of patients with

    2011-12-01

    The present study aimed to investigate associations of both parent-reported and child-perceived parenting styles and parent-reported parenting practices with child weight and weight-related behaviours. Participants were 175 children (56% female) aged between 7 and 11, and their primary caregivers (91% female), recruited through South Australian primary schools. Children completed measures of parenting style, attitude toward fruit, vegetables, and non-core food, and attraction to physical activity. Parents completed measures of parenting style and domain-specific parenting practices (feeding and activity-related practices) and reported on child dietary intake, physical activity, and sedentary behaviour. Objective height and weight measurements were taken from children, from which body mass index (BMI) was calculated. Child-reported parenting style and parent-reported parenting practices were uniquely associated with child weight-related outcomes, but styles and practices did not interact in their association with child outcomes. Child-reported parenting style was associated with child food and activity attitudes, whereas parent-reported parenting style was not associated with child outcomes. The findings of the present study generally support the recommendation of a parenting style high in demandingness and responsiveness for supporting healthy child weight-related behaviours, along with appropriate domain-specific practices. The child's perspective should be incorporated into research involving child outcomes wherever possible. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

    Eating disorders are understudied among male veterans, who may be at increased risk due to the high rates of trauma exposure and experiences of multiple traumatization in this population. This study sought to examine the associations between specific types of trauma (i.e., childhood physical abuse, adult physical assault, childhood sexual abuse, adult sexual assault, and military-related trauma) and eating disorder symptoms in a large, nationally-representative sample of trauma-exposed male veterans. Survey data were collected from N = 642 male veterans. Traumatic experiences in childhood and adulthood were assessed using the Trauma History Screen and the National Stressful Events Survey. Eating disorder symptoms were assessed with the Eating Disorder Diagnostic Scale. Analyses also controlled for age and body mass index. Multiple traumatization was associated with increased eating disorder symptoms. However, military-related trauma was the only trauma type that was uniquely associated with eating disorder symptoms when controlling for other trauma types. Examination of different types of military-related trauma indicated that this association was not driven by exposure to combat. Noncombat, military-related trauma was associated with eating disorder symptom severity in male veterans. Results highlight the need for better assessment of eating disorder symptoms in this population. © 2017 Wiley Periodicals, Inc.

    There is a paucity of knowledge on the association between different foot posture quantified by Foot Posture Index (FPI) and Quadriceps angle (Q-angle) with development of running-related injuries. Earlier studies investigating these associations did not include an objective measure of the amount...... of running performed. Therefore, the purpose of this study was to investigate if kilometers to running-related injury (RRI) differ among novice runners with different foot postures and Q-angles when running in a neutral running shoe....

    Variation in taste perception and exposure to risk factors of taste alterations have been independently linked with elevated adiposity. Using a laboratory database, taste-adiposity associations were modeled and examined for whether taste functioning mediates the association between taste-related risk factors and adiposity. Healthy women (n = 407, 35.5 ± 16.9 y) self-reported histories of risk factors of altered taste functioning (tonsillectomy, multiple ear infections, head trauma) and were assessed for taste functioning (tongue-tip and whole-mouth intensities of quinine and salt) and density of taste papillae. Twenty-four percent had elevated waist circumferences; thirty-nine percent had overweight or obesity. Using structural equation modeling, direct and indirect associations between taste-related risk factors, taste functioning, and adiposity were tested. In models with good fit, elevated central adiposity was explained directly by history of risk factors (tonsillectomy, multiple ear infections) and directly by lower taste functioning (lower tongue-tip taste function, lower papillae density). Risk factors of taste alterations were significantly associated with lower taste functioning, with taste mediating the association between head trauma and reduced adiposity. This large laboratory-based study supports associations between taste-related risk factors, taste functioning, and adiposity. These findings need to be confirmed with other population-based studies, including the National Health and Nutrition Examination Survey 2013-2014 taste data. © 2017 The Obesity Society.

    This prospective study explored the potential mediating role of health-related behavior (alcohol involvement, diet, television viewing, and physical activity) in the association between personality and change in memory performance over 2 years. A nationally representative sample of 8,376 U.K. participants aged 55 years and older (4,572 women, 3,804 men) completed self-report measures of personality and health-related behavior in 2010, and completed a memory performance task in 2010 and 2012. After removing variance associated with potential confounding variables, neuroticism and agreeableness had negative associations, and openness and conscientiousness positive associations with change in memory performance. There were no moderation effects by age, sex, education level, or ethnicity. Multiple mediator models demonstrated that physical activity, television viewing, and alcohol intake mediated associations between personality and change in memory performance. These findings provide evidence that the association between personality and memory performance in older adults can be explained, in part, through health-related behavior.

    To explore contributing factors (CF) associated to related critical patients safety incidents. SYREC study pos hoc analysis. A total of 79 Intensive Care Departments were involved. The study sample consisted of 1.017 patients; 591 were affected by one or more incidents. The CF were categorized according to a proposed model by the National Patient Safety Agency from United Kingdom that was modified. Type, class and severity of the incidents was analyzed. A total 2,965 CF were reported (1,729 were associated to near miss and 1,236 to adverse events). The CF group more frequently reported were related patients factors. Individual factors were reported more frequently in near miss and task related CF in adverse events. CF were reported in all classes of incidents. The majority of CF were reported in the incidents classified such as less serious, even thought CF patients factors were associated to serious incidents. Individual factors were considered like avoidable and patients factors as unavoidable. The CF group more frequently reported were patient factors and was associated to more severe and unavoidable incidents. By contrast, individual factors were associated to less severe and avoidable incidents. In general, CF most frequently reported were associated to near miss.

    Although traumatic events are presumed to cause sleep disturbances, particularly insomnia, sleep in populations subjected to forced displacement has received little attention. The present study examined the prevalence of insomnia and associated factors in internally displaced persons (IDPs) from Abkhazia 15 years after displacement to Tbilisi. Detailed subjective information about sleep-wake habits, sleep-related and stress-related parameters were obtained from 87 IDPs categorized into good sleepers and insomniacs. The Insomnia Severity Index, Perceived Stress Scale and Beck Depression Inventory were administered. The incidence of insomnia was 41.4%. The majority of insomniacs strongly believed that war-related stress accounted for the onset of their insomnia. Stepwise regression (95% confidence interval) revealed four variables significantly associated with insomnia status: self-estimated influence of war related stress (odds ratio (OR) = 2.51), frequency of nightmares (OR = 1.6), Perceived Stress Scale score (OR = 1.14) and Beck Depression Inventory score (OR = 1.12). Insomnia in IDPs was strongly related to war-associated remembered stress. ‛Over thinking' about major stress exposure enhanced IDPs' vulnerability to insomnia. These findings have implications for the management of insomnia and associated impairment of daytime functioning in IDPs. Copyright © 2011 John Wiley & Sons, Ltd.

    Full Text Available CONTEXT: Pubertal timing is under strong genetic control and its early onset associates with several adverse health outcomes in adulthood, including obesity, type 2 diabetes and cardiovascular disease. Recent data indicate strong association between pubertal timing and genetic variants near LIN28B, but it is currently unknown whether the gene contributes to the association between puberty and adult disease. OBJECTIVE: To elucidate the putative genetic link between early puberty and adult disease risk, we examined the association of two genetic variants near LIN28B with adult body size and metabolic profiles in randomly ascertained adult Finnish males and females. METHODS: Two single nucleotide polymorphisms (SNPs, rs7759938, the lead SNP previously associated with pubertal timing and height, and rs314279, previously also associated with menarcheal age but only partially correlated with rs7759938 (r(2 = 0.30, were genotyped in 26,636 study subjects participating in the Finnish population survey FINRISK. Marker associations with adult height, weight, body mass index (BMI, hip and waist circumference, blood glucose, serum insulin and lipid/lipoprotein levels were determined by linear regression analyses. RESULTS: Both rs7759938 and rs314279 associated with adult height in both sexes (p = 2×10(-6 and p = 0.001. Furthermore, rs314279 associated with increased weight in females (p = 0.001. Conditioned analyses including both SNPs in the regression model verified that rs314279 independently associates with adult female weight, BMI and hip circumference (p<0.005. Neither SNP associated with glucose, lipid, or lipoprotein levels. CONCLUSION: Genetic variants near the puberty-associated gene LIN28B associate with adult weight and body shape in females, suggesting that the gene may tag molecular pathways influencing adult adiposity-related traits.

    Full Text Available We investigate the association between related party transactions (RPT and real earnings management (REM. We also investigate the role of internal governance mechanism through the effectiveness of board of commissioner and audit committee in mitigating the association between RPT and REM. Our research sample consists of 386 firm-years of manufacturing firms listed in Indonesian Stock Exchange (IDX from year 2010 - 2014. Using linear regression, we find evidence that RPT has positive association with REM, only when the firm has higher RPT but not in the lower RPT. We find a contradictory result that board of commissioners strengthen the positive association between RPT and REM. Finally, we find evidence that the effectiveness of audit committees weaken the positive association between RPT and REM, both in full sample and in high RPT sample.

    Dieting and concern with weight were found to be associated with psychological and neurological symptoms observed in cases of severe semi-starvation. College students of both sexes (n 292) and high school females (n121) rated themselves on dietary restraint and psychological and physical symptoms that were prevalent in men after 24 weeks in the Minnesota semi-starvation experiment of 1944-5. Apprehension, irritability, and moodiness were associated with a high concern with restraint. Blank spells, hunger pain, concern for health, and social withdrawal were associated with a history of restraint. Depression, lower self-esteem, eating behavior patterns, apathy, and decreased motivation were associated with both restraint parameters. Our results suggest that normal dieting may be more closely related to psychological and health risks associated with chronic semi-starvation than is commonly believed.

    Family studies suggest a genetic component to the etiology of chronic kidney disease (CKD) and end stage renal disease (ESRD). Previously, we identified 16 loci for eGFR in genome-wide association studies, but the associations of these single nucleotide polymorphisms (SNPs) for incident CKD or ESRD are unknown. We thus investigated the association of these loci with incident CKD in 26,308 individuals of European ancestry free of CKD at baseline drawn from eight population-based cohorts followed for a median of 7.2 years (including 2,122 incident CKD cases defined as eGFR CKD; p-values ranged from p = 4.1e-9 in UMOD to p = 0.03 in GCKR. After adjusting for baseline eGFR, six of these loci remained significantly associated with incident CKD (UMOD, PRKAG2, ANXA9, DAB2, DACH1, and STC1). SNPs in UMOD (OR = 0.92, p = 0.04) and GCKR (OR = 0.93, p = 0.03) were nominally associated with ESRD. In summary, the majority of eGFR-related loci are either associated or show a strong trend towards association with incident CKD, but have modest associations with ESRD in individuals of European descent. Additional work is required to characterize the association of genetic determinants of CKD and ESRD at different stages of disease progression.

    Full Text Available Purpose. The purpose of this study was to investigate the expression of cancer-associated fibroblast- (CAF- related proteins and the implications in breast phyllodes tumor (PT. Methods. Tissue microarrays of 194 PT cases (151 benign PT, 27 borderline PT, and 16 malignant PT were constructed. We performed immunohistochemical staining for CAF-related proteins (podoplanin, prolyl 4-hydroxylase, FAPα, S100A4, PDGFR α/β, and NG2 and analyzed the results according to clinicopathologic parameters. Results. Expression of PDGFRα and PDGFRβ in the stromal component increased with increasing histologic grade of PT (p=0.003 and p=0.034, resp.. Among clinicopathologic parameters, only expression of FAPα in stroma was associated with distant metastasis (p=0.002. In univariate analysis, stromal expression of PDGFRα was associated with shorter overall survival (p=0.002. In Cox multivariate analysis, stromal overgrowth and PDGFRα stromal positivity were associated with shorter overall survival (p=0.006 and p=0.050, resp.. Furthermore, expression of PDGFRβ in stroma was associated with shorter overall survival in patients with malignant PT (p=0.041. Conclusion. Stromal expression of PDGFRα and PDGFRβ increased with increasing histologic grade of PT. In addition, PDGFR stromal positivity was associated with shorter overall survival. These results suggest that CAFs are associated with breast PT progression.

    Full Text Available The existence of multiple inherited disorders of iron metabolism suggests genetic contributions to iron deficiency. We previously performed a genome-wide association study of iron-related single nucleotide polymorphisms (SNPs using DNA from white men aged ≥ 25 y and women ≥ 50 y in the Hemochromatosis and Iron Overload Screening (HEIRS Study with serum ferritin (SF ≤ 12 µg/L (cases and controls (SF >100 µg/L in men, SF >50 µg/L in women. We report a follow-up study of white, African-American, Hispanic, and Asian HEIRS participants, analyzed for association between SNPs and eight iron-related outcomes. Three chromosomal regions showed association across multiple populations, including SNPs in the TF and TMPRSS6 genes, and on chromosome 18q21. A novel SNP rs1421312 in TMPRSS6 was associated with serum iron in whites (p = 3.7 × 10(-6 and replicated in African Americans (p = 0.0012.Twenty SNPs in the TF gene region were associated with total iron-binding capacity in whites (p<4.4 × 10(-5; six SNPs replicated in other ethnicities (p<0.01. SNP rs10904850 in the CUBN gene on 10p13 was associated with serum iron in African Americans (P = 1.0 × 10(-5. These results confirm known associations with iron measures and give unique evidence of their role in different ethnicities, suggesting origins in a common founder.

    Full Text Available Abstract Background Previous studies suggested that the abnormality of metabolism is a newly identified risk factor in HBV-related hepatocellular carcinoma (HCC. The association between metabolic factors and hepatocellular carcinoma (HCC has not been clarified up to now. This study was conducted to investigate the prevalence of metabolic abnormalities in HCC and to probe the association between metabolic parameters and liver function as well, so as to evaluate the interactions between metabolism and the development of HBV-related HCC. Methods Totally 179 cases of HBV-related HCC, who were surgically treated and pathologically confirmed were enrolled. HBV carriers (n = 100 and healthy controls (n = 150 were recruited from routine physical examination during the same period. Body mass index (BMI was obtained from medical documentation. All the metabolic-related parameters and liver function tests were determined with routine biochemical or immunological analytic methods. Malondialdehyde (MDA and total antioxidant capacity(TAOCwere detected by chemical analytic methods. A stratified analysis was conducted according to BMI, glycated albumin (GA, free fatty acids (FFA, and the relationships between the metabolic-related parameters and liver functions were analyzed in HCC and control subjects. Results HCC group showed significantly high levels of mean BMI, serum glucose, low serum lipids levels than controls (P Conclusions Metabolic abnormalities are closely associated with the occurrence and development of HBV-related HCC. Oxidative stress and/or lipid peroxidation might be involved in the pathogenesis and acceleration of liver function impairments in HCC.

    This study aimed to examine whether educational stressors and relational stressors are associated with burnout in medical students and to test social support as a moderator between stressors and burnout. A total of 263 medical students attending Gyeongsang National University composed the study sample. A standardized questionnaire was used to investigate educational and relational stressors, three dimensions of burnout, and social support of medical students. The findings showed that overall burnout is very high among Korean medical students, with 9.9% totally burned out. Educational and relational stressors were significantly associated with the risk of burnout in medical students after controlling for socio-demographics and health behaviors. Social support moderated educational and relational stressors on personal accomplishment, but did not moderate stressors on emotional exhaustion and depersonalization. Burnout level is substantially high among Korean medical students. Educational and relational stressors are significantly associated with burnout risk in Korean medical students. Social support had moderated educational and relational stressors on personal accomplishment. The results suggest that more social support for medical students is needed to buffer stressors on and burnout.

    Clinical evidence reveals the importance of mother-newborn bonding experience for health promoting and maintenance of human life. If the newborn lacks care and affection, she/he may develop an attachment disorder. A predictive scale regarding the risk of mothernewborn relationships is available, which makes possible an early intervention to prevent the development of relational disorders. The aim of this study is to apply the Kimelman measurement scale to determine the relational risk in mother-newborn pairs, as well as the prevalence and the associated biopsychosocial variables. A cross-sectional study with a probabilistic sample of 333 mother-infant pairs in postpartum maternity at Temuco hospital. The Kimelman mother-newborn attachment assessment guide was used. Biopsychosocial variables were obtained from the mothers studied. The association of biopsychosocial variables with relational risk was analyzed using OR and confidence intervals of 95%. The prevalence of high relational risk was 43.8%. The associated biopsychosocial variables included, women with no steady partner, single parent, teenage mothers, unwanted and unplanned pregnancy. Almost half of the mothers were in the high risk group. Early identification of relational risk and its related variables could help in the intervention in this vulnerable group. Copyright © 2015.

    Full Text Available Goal-directed behavior relies on the integration of anticipated outcomes into action planning based on acquired knowledge about the current contingencies between behavioral responses (R and desired outcomes (O under specific stimulus conditions (S. According to ideomotor theory, bidirectional R-O associations are an integral part of this knowledge structure. Previous EEG studies have identified neural activity markers linked to the involvement of such associations, but the initial acquisition process has not yet been characterized. The present study thus examined brain-electrical activity dynamics during the rapid acquisition of novel bidirectional R-O associations during instructed S-R learning. Within a trial, we inspected response-locked and stimulus-locked activity dynamics in order to identify markers linked to the forward and backward activation of bidirectional R-O associations as they were being increasingly strengthened under forced choice conditions. We found that a post-response anterior negativity following auditory outcomes was increasingly attenuated as a function of the acquired association strength. This suggests that previously reported action-induced sensory attenuation effects under extensively trained free choice conditions can be established within few repetitions of specific R-O pairings under forced choice conditions. Furthermore, we observed the even more rapid development of a post-response but pre-outcome fronto-central positivity which was reduced for high R-O learners which might indicate the rapid deployment of preparatory attention towards predictable outcomes. Finally, we identified a learning-related stimulus-locked activity modulation within the visual P1-N1 latency range which might reflect the multi-sensory integration of the perceived antecedent visual stimulus the anticipated auditory outcome.

    The impact of specific allergic rhinitis symptoms on patient quality of life (QOL) is currently unknown. In this study, we sought to determine the association between nasal and extranasal symptoms of allergic rhinitis with general health-related QOL. A total of 150 participants with ages > 18 years and persistent allergic rhinitis were prospectively recruited for this cross-sectional study. General health-related QOL was measured by using the visual analog scale (VAS) from the five-dimension EuroQol QOL survey (EQ-5D). The severity of nasal and extranasal symptoms was measured by using the 22-item Sino-Nasal Outcome Test (SNOT-22). The severity of nasal obstruction was measured by using the Nasal Obstruction Severity Evaluation (NOSE) scale. Each participant also completed a Rhinitis Control Assessment Test (RCAT). The total SNOT-22 score was significantly correlated with RCAT (r = -0.68 [95% confidence interval {CI}, -0.75 to -0.58]; p < 0.001) and EQ-5D VAS (r = -0.44 [95% CI, -0.56 to -0.30]; p < 0.001). Of the 22 symptoms assessed on the SNOT-22, sleep-related symptoms, and otologic symptoms were associated with the greatest decrease in general health-related QOL. Nasal symptoms were least associated with general health-related QOL. The symptom of nasal obstruction was not at all associated with general health-related QOL (p = 0.267). We confirmed this finding by showing no significant correlation between the NOSE score and EQ-5D VAS (r = -0.05 [95% CI, -0.21 to 0.12]; p = 0.582). Sleep and otologic symptoms were associated with the greatest negative impact on QOL in adults with persistent allergic rhinitis and should be routinely assessed in their clinical evaluation.

    Objective To test the hypothesis that late-life depression is associated with dementia related pathology. Method Older participants (n=1,965) in 3 longitudinal clinical-pathologic cohort studies who had no cognitive impairment at baseline underwent annual clinical evaluations for a mean of 8.0 years (SD = 5.0). We defined depression diagnostically, as major depression during the study period, and psychometrically, as elevated depressive symptoms during the study period, and established their relation to cognitive outcomes (incident dementia, rate of cognitive decline). A total of 657 participants died and underwent a uniform neuropathologic examination. We estimated the association of depression with 6 dementia related markers (tau tangles, beta-amyloid plaques, Lewy bodies, hippocampal sclerosis, gross and microscopic infarcts) in logistic regression models. Results In the full cohort, 9.4% were diagnosed with major depression and 8.6% had chronically elevated depressive symptoms, both of which were related to adverse cognitive outcomes. In the 657 persons who died and had a neuropathologic examination, higher beta-amyloid plaque burden was associated with higher likelihood of major depression (present in 11.0%; odds ratio = 1.392, 95% confidence interval = 1.088, 1.780) but not with elevated depressive symptoms (present in 11.3%; odds ratio = 0.919, 95% confidence interval = 0.726, 1.165). None of the other pathologic markers was related to either of the depression measures. Neither dementia nor antidepressant medication modified the relation of pathology to depression. Conclusion The results do not support the hypothesis that major depression is associated with dementia related pathology. PMID:26237627

    Cigarette smoking is an environmental risk factor for many chronic diseases, and disease risk can often be managed by smoking control. Smoking can induce cellular and molecular changes, including epigenetic modification, but the short- and long-term epigenetic modifications caused by cigarette smoking at the gene level have not been well understood. Recent studies have identified smoking-related DNA methylation (DNAm) sites in Caucasians. To determine whether the same DNAm sites associate with smoking in African Americans, and to identify novel smoking-related DNAm sites, we conducted a methylome-wide association study of cigarette smoking using a discovery sample of 972 African Americans, and a replication sample of 239 African Americans with two array-based methods. Among 15 DNAm sites significantly associated with smoking after correction for multiple testing in our discovery sample, 5 DNAm sites are replicated in an independent cohort, and 14 sites in the replication sample have effects in the same direction as in the discovery sample. The top two smoking-related DNAm sites in F2RL3 (factor II receptor-like 3) and GPR15 (G-protein-coupled receptor 15) observed in African Americans are consistent with previous findings in Caucasians. The associations between the replicated DNAm sites and smoking remain significant after adjusting for genetic background. Despite the distinct genetic background between African Americans and Caucasians, the DNAm from the two ethnic groups shares common associations with cigarette smoking, which suggests a common molecular mechanism of epigenetic modification influenced by environmental exposure.

    Low adherence to guidelines for weight-related behaviours (e.g. dietary intake and physical activity) among US children underscores the need to better understand how parental factors may influence children's obesity risk. In addition to most often acting as primary caregiver to their children, women are also known to experience greater levels of stress than men. This study systematically reviewed associations between maternal stress and children's weight-related behaviours. Our search returned 14 eligible articles, representing 25 unique associations of maternal stress with a distinct child weight-related behaviour (i.e. healthy diet [n = 3], unhealthy diet [n = 6], physical activity [n = 7] and sedentary behaviour [n = 9]). Overall, findings for the relationship between maternal stress and children's weight-related behaviours were mixed, with no evidence for an association with children's healthy or unhealthy dietary intake, but fairly consistent evidence for the association of maternal stress with children's lower physical activity and higher sedentary behaviour. Recommendations for future research include prioritizing prospective designs, identifying moderators, and use of high-resolution, real-time data collection techniques to elucidate potential mechanisms. © 2017 World Obesity Federation.

    Most genome-wide association studies are confined to middle-aged populations. It is unclear whether associations between single nucleotide polymorphisms (SNPs) and obesity persist in old age. We aimed to relate 10 body mass index (BMI)-associated SNPs to weight, BMI, % fat, visceral and subcutaneous adipose tissue in Health ABC and AGES-Reykjavik comprising 4,846 individuals of European Ancestry, and 1,139 African Americans over age 65. SNPs were scaled using effect estimates from candidate SNPs. In Health ABC, a SNP near GNPDA2 was modestly associated with weight and SAT area (p = .008, p = .001). Risk score (sum of scaled SNPs) was associated with weight, BMI, and SAT area (p BMI, visceral adippose tissue, subcutaneous adipose tissue, or % fat in AGES-Reykjavik. In African Americans, a SNP near SEC16B was weakly associated with weight (p = .04). In this sample of older adults, no BMI-associated SNPs were associated with weight or adiposity.

    Risk perceptions are important in HIV research and interventions; mixed results were found between HIV-related perceptions and behaviors. We interviewed 377 sexually active injecting drug users in China, finding mixed associations between HIV-related risk perception assessed by two general measures and two previous risk behaviors (syringe sharing: p.05) – partially supporting the ‘reflective hypothesis’ that reflection on previous behaviors increases risk perceptions. When we use specific measures for risk perceptions (HIV transmission via unprotected sex with specific types of sex partner and via syringe sharing) and use behavioral intention to adopt protective risk behaviors (condom use and avoid syringe sharing totally) as dependent variables, positive significant associations were observed – supporting the motivational hypothesis that risk perceptions motivate one to adopt protective behaviors. The direction and significance of the associations of concern depends on types of measures used. It has important implications on research design, data interpretation and services. PMID:23284896

    This study aimed to summarise the function-related goals set by older people and to explore gender differences in goal selection, and associations between balance-related goals and fall history, self-rated balance and fear of falling. We included community-dwelling people aged 60+ participating in two randomised controlled trials. Participants nominated two function-related goals, which were summarised into components of the International Classification of Functioning, Disability and Health (ICF). Chi-square analyses were used to explore associations between goal types and participant characteristics. Goals related to recreation and leisure, and walking were the most common function-related goals selected. Men and women set similar goals. Participants who had poor/fair self-reported balance were more likely to set a balance-related goal than people with good self-rated balance. In contrast, fallers and participants who had fear of falling were not more likely to select a balance-related goal than non-fallers and participants who had no fear of falling, respectively.

    2016-01-01

    Age-related macular degeneration is the leading cause of adult blindness in the developed world. Thus, major endeavors to understand the risk factors and pathogenesis of this disease have been undertaken. Reticular macular disease is a proposed subtype of age-related macular degeneration correlating histologically with subretinal drusenoid deposits located between the retinal pigment epithelium and the inner segment ellipsoid zone. Reticular lesions are more prevalent in females and in older age groups and are associated with a higher mortality rate. Risk factors for developing age-related macular degeneration include hypertension, smoking, and angina. Several genes related to increased risk for age-related macular degeneration and reticular macular disease are also associated with cardiovascular disease. Better understanding of the clinical and genetic risk factors for age-related macular degeneration and reticular macular disease has led to the hypothesis that these eye diseases are systemic. A systemic origin may help to explain why reticular disease is diagnosed more frequently in females as males suffer cardiovascular mortality at an earlier age, before the age of diagnosis of reticular macular disease and age-related macular degeneration.

    Full Text Available Lipid metabolism may be involved in the pathogenic mechanism of age-related macular degeneration (AMD. However, conflicting results have been reported in the associations of AMD with blood lipids. We performed a meta-analysis including a total of 19 studies to evaluate associations between blood lipids and this disease. The result reported that the high level of high-density lipoprotein cholesterol (HDL-C obtained with an increment of 1 mmol/L could result in a significantly increase in the AMD risk of approximately 18% (relative risk (RR, 1.18; 95% confidence interval (CI, 1.01 to 1.35; I2 = 53.8%; p = 0.007. High levels of total cholesterol (TC, low-density lipoprotein cholesterol (LDL-C, and triglycerides (TG were significantly associated with a decreased risk of AMD (RRs ranging from 0.92 to 0.95; all p < 0.05. The stratified analysis based on AMD subtypes showed that these blood lipids were only significantly associated with the risk of early AMD (all p < 0.05. The association between the blood lipids and AMD risk did not differ substantially based on the other characteristics of the participants. A high HDL-C level was associated with an increased AMD risk, whereas participants with high TC, LDL-C, and TG concentrations may show a decreased risk for this disease. Further well-designed large studies are warranted to confirm the conclusions.

    Humans display structural and functional asymmetries in brain organization, strikingly with respect to language and handedness. The molecular basis of these asymmetries is unknown. We report a genome-wide association study meta-analysis for a quantitative measure of relative hand skill in individuals with dyslexia [reading disability (RD)] (n = 728). The most strongly associated variant, rs7182874 (P = 8.68 × 10(-9)), is located in PCSK6, further supporting an association we previously reported. We also confirmed the specificity of this association in individuals with RD; the same locus was not associated with relative hand skill in a general population cohort (n = 2,666). As PCSK6 is known to regulate NODAL in the development of left/right (LR) asymmetry in mice, we developed a novel approach to GWAS pathway analysis, using gene-set enrichment to test for an over-representation of highly associated variants within the orthologs of genes whose disruption in mice yields LR asymmetry phenotypes. Four out of 15 LR asymmetry phenotypes showed an over-representation (FDR ≤ 5%). We replicated three of these phenotypes; situs inversus, heterotaxia, and double outlet right ventricle, in the general population cohort (FDR ≤ 5%). Our findings lead us to propose that handedness is a polygenic trait controlled in part by the molecular mechanisms that establish LR body asymmetry early in development.

    To investigate the associations between midlife work-related stress and late-life cognition in individuals without dementia from the general population. The Cardiovascular Risk Factors, Aging and Dementia (CAIDE) study population (n = 2000) was randomly selected from independent Finnish population-based surveys (baseline mean age 50 years). Participants underwent two re-examinations in late life (mean age 71 and 78 years, respectively). 1511 subjects participated in at least one re-examination (mean total follow-up 25 years). Work-related stress was measured using two questions on work demands administered in midlife. Multiple cognitive domains were assessed. Analyses were adjusted for several potential confounders. Higher levels of midlife work-related stress were associated with poorer performance on global cognition [β-coefficient, -0.02; 95% confidence interval (CI), -0.05 to -0.00], and processing speed [β -0.03, CI -0.05 to -0.01]. Results remained significant after adjusting for potential confounders. Work-related stress was not significantly associated with episodic memory, executive functioning, verbal fluency or manual dexterity. This study shows that global cognition and processing speed may be particularly susceptible to the effects of midlife work-related stress.

    Poor social relations are supposed to contribute to adverse health behaviour. We examined this association and the role of low socio-economic position. We regressed health behaviour on composite variables of the two exposures of social relations and socio-economic position (SEP). Social relations included networks and support; health behaviour was analysed in terms of smoking, poor nutrition and physical inactivity; socio-economic position comprised of income and education. Cross sectional data from a population based epidemiological study in German (4,814 men and women aged 45-75) was analysed. Among the indicators for social relations, social isolation was consistently associated with adverse health behaviour; social support showed modest effect. A combination of poor social relations and low SEP displayed stronger (additive) associations with adverse health behaviour than each factor alone. However, superadditivity was excluded. Given the important role of health adverse behaviour in chronic disease development, results underline the relevance of social environment and socio-economic structure in Public Health interventions.

As a factor affecting nurse turnover, newly graduated nurses' occupational commitment and its associations with work-related factors needs exploring to retain adequate workforce. Nurses' commitment has mainly been studied as organisational commitment, but newly graduated nurses' occupational commitment and its association with work-related factors needs further studying. This study used descriptive, cross-sectional, correlation design. A convenience sample of 318 newly graduated nurses in Finland participated responding to an electronic questionnaire. Statistical software, NCSS version 9, was used in data analysis. Frequencies, percentages, ranges, means and standard deviations summarised the data. Multivariate Analyses of Variance estimated associations between occupational commitment and work-related variables. IBM SPSS Amos version 22 estimated the model fit of Occupational Commitment Scale and Nurse Competence Scale. Newly graduated nurses' occupational commitment was good, affective commitment reaching the highest mean score. There was a significant difference between the nurse groups in favour of nurses at higher competence levels in all subscales except in limited alternatives occupational commitment. Multivariate analyses revealed significant associations between subscales of commitment and competence, turnover intentions, job satisfaction, earlier professional education and work sector, competence counting only through affective dimension. The association between occupational commitment and low turnover intentions and satisfaction with nursing occupation was strong. Higher general competence indicated higher overall occupational commitment. Managers' recognition of the influence of all dimensions of occupational commitment in newly graduated nurses' professional development is important. Follow

    To examine the associations between demographic characteristics, health behaviors, workplace health culture, and health-related outcomes in Chinese workplaces. A total of 1508 employees from 10 administrative offices and 6 enterprises were recruited for a cross-sectional survey. Self-administered questionnaires mainly addressed demographic characteristics, health behaviors, workplace health culture, and health-related outcomes including self-rated health, mental health, and happiness. The proportion of participants who reported good health-related outcomes was significantly higher in those working in administrative offices than those working in enterprises. The result of the potential factors related to self-rated health (SRH), mental health, and happiness by logistic regression analyses showed that age and income were associated with SRH; type of workplace, age, smoking, and health culture at the workplace level were associated with mental health; and beneficial health effects of direct leadership was positively associated with happiness. Moreover, there were some similar results among 3 multivariate regression models. Firstly, good SRH (Odds Ratio (OR) = 1.744), mental health (OR = 1.891), and happiness (OR = 1.736) were more common among highly physically active participants compared with those physical inactive. Furthermore, passive smoking was negatively correlated with SRH (OR = 0.686), mental health (OR = 0.678), and happiness (OR = 0.616), while health culture at the individual level was positively correlated with SRH (OR = 1.478), mental health (OR = 1.654), and happiness (OR = 2.916). The present study indicated that workplace health culture, health behaviors, and demographic characteristics were associated with health-related outcomes. Furthermore, individual health culture, physical activity, and passive smoking might play a critical role in workplace health promotion.

    Background The phantom auditory perception of subjective tinnitus is associated with aberrant brain activity as evidenced by magneto- and electroencephalographic studies. We tested the hypotheses (1) that psychoacoustically measured tinnitus loudness is related to gamma oscillatory band power, and (2) that tinnitus loudness and tinnitus-related distress are related to distinct brain activity patterns as suggested by the distinction between loudness and distress experienced by tinnitus patients. Furthermore, we explored (3) how hearing impairment, minimum masking level, and (4) psychological comorbidities are related to spontaneous oscillatory brain activity in tinnitus patients. Methods and Findings Resting state oscillatory brain activity recorded electroencephalographically from 46 male tinnitus patients showed a positive correlation between gamma band oscillations and psychoacoustic tinnitus loudness determined with the reconstructed tinnitus sound, but not with the other psychoacoustic loudness measures that were used. Tinnitus-related distress did also correlate with delta band activity, but at electrode positions different from those associated with tinnitus loudness. Furthermore, highly distressed tinnitus patients exhibited a higher level of theta band activity. Moreover, mean hearing loss between 0.125 kHz and 16 kHz was associated with a decrease in gamma activity, whereas minimum masking levels correlated positively with delta band power. In contrast, psychological comorbidities did not express significant correlations with oscillatory brain activity. Conclusion Different clinically relevant tinnitus characteristics show distinctive associations with spontaneous brain oscillatory power. Results support hypothesis (1), but exclusively for the tinnitus loudness derived from matching to the reconstructed tinnitus sound. This suggests to preferably use the reconstructed tinnitus spectrum to determine psychoacoustic tinnitus loudness. Results also support

    The aim of the current study was to examine the mediating role of alcohol-related memory associations in the relation between perceived parental drinking and the onset of adolescents' alcohol use. Gender and grade were also included in the analyses. We tested a mediation model within a structural path modelling framework using longitudinal data (two waves). The sample consisted of 608 Canadian adolescents (42.9% boys), who did not have any alcohol experiences at the first measurement. The adolescents were recruited from all grades 7-9 classes in a large school district in western Canada. Alcohol-related memory associations were tested with the Word Association Test. We used adolescent self-reports of alcohol use and parental drinking. Results clearly showed a mediation effect of alcohol-related memory associations [estimate = 0.023, 95% confidence interval (CI): 0.002-0.044). That is, parental drinking as perceived by the adolescent was related positively to alcohol-related memory associations, which in turn predicted adolescents' alcohol use a year later. Gender and grade were related to alcohol-related memory associations. That is, boys and adolescents of higher grades had more memory associations. Children appear to form memory associations related to alcohol before they ever drink alcohol themselves, and these associations appear to mediate the link between their perceptions of their parents' drinking and their own initial alcohol use. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    Work-related asthma is common and yet remains a challenge to diagnose. Access to a listing of agents associated with work-related asthma has been suggested as useful in assisting in the diagnosis. The Association of Occupational and Environmental Clinics (AOEC) developed criteria that were used to review the peer-reviewed medical literature published in English. Based on this review, substances were designated either as a sensitizing agent or an irritant. The reviews were conducted by a board certified internist/pulmonologist/occupational medicine specialist from 2002 to 2007 and a board certified internist/occupational medicine physician from 2008- date. All reviews were then reviewed by the nine member AOEC board of directors. The original list of agents associated with new onset work-related asthma was derived from the tables of a text book on work-related asthma. After 13 years of review, there are 327 substances designated as asthma agents on the AOEC list; 173 (52.9%) coded as sensitizers, 35 (10.7%) as generally recognized as an asthma causing agent, four (1.2%) as irritants, two (0.6%) as both a sensitizer and an irritant and 113(34.6%) agents that still need to be reviewed. The AOEC has developed a readily available web based listing of agents associated with new onset work-related asthma in adults. The listing is based on peer-reviewed criteria. The listing is updated twice a year. Regular review of the peer-reviewed medical literature is conducted to determine whether new substances should be added to the list. Clinicians should find the list useful when considering the diagnosis of work-related asthma. Copyright © 2015 Elsevier Ltd. All rights reserved.

    It is noted that large quantities of atmospheric aerosols with composition SO4(-2), NO3(-1), and NH4(+1) have been detected in highly industrialized areas. Most aerosol products come from energy-related fuel combustion. Fluid mechanics simulation of both microphysical and macrophysical processes is considered in studying the time dependent evolution of the saturation spectra of condensation nuclei associated with polluted and clean atmospheres during the time periods of advection fog formation. The results demonstrate that the condensation nuclei associated with a polluted atmosphere provide more favorable conditions than condensation nuclei associated with a clean atmosphere to produce dense advection fog, and that attaining a certain degree of supersaturation is not necessarily required for the formation of advection fog having condensation nuclei associated with a polluted atmosphere.

    Audiometric evaluations and mini-mental state exams were obtained in 34 subjects over the age of 80 who have had brain MRIs in the past 6 years. CSF and parenchymal brain volumes (whole brain and by lobe were obtained through a novel, fully automated algorithm. Atrophy was calculated by taking the ratio of CSF to parenchyma. High frequency hearing loss was associated with disproportional temporal lobe atrophy relative to whole brain atrophy independent of age (r = 0.471, p = 0.005. Mental state was associated with frontoparietal atrophy but not to temporal lobe atrophy, which is consistent with known results. Our method demonstrates that hearing loss is associated with temporal lobe atrophy and generalized whole brain atrophy. Our algorithm is efficient, fully automated, and able to detect significant associations in a small cohort.

    Full Text Available Observational studies suggest that obese men have a lower risk of incident prostate cancer, but an increased risk of advanced and fatal cancers. These observations could be due to confounding, detection bias, or a biological effect of obesity. Genetic studies are less susceptible to confounding than observational epidemiology and can suggest how associations between phenotypes (such as obesity and diseases arise. To determine whether the associations between obesity and prostate cancer are causal, we conducted a genetic association study of the relationship between a single nucleotide polymorphism known to be associated with obesity (FTO rs9939609 and prostate cancer. Data are from a population-based sample of 1550 screen-detected prostate cancers, 1815 age- and general practice matched controls with unrestricted prostate specific antigen (PSA values and 1175 low-PSA controls (PSA <0.5 ng/ml. The rs9939609 A allele, which was associated with higher BMI in the sample, was inversely associated with overall (odds ratio (OR versus all controls  = 0.93; 95% confidence interval (CI: 0.85-1.02 p = 0.12 per allele and low-grade (OR = 0.90; 0.81-0.99 p = 0.03 per allele prostate cancer risk, but positively associated with high-grade cancer among cases (OR high- versus low-grade cancer  = 1.16; 0.99-1.37 p = 0.07 per allele. Although evidence for these effects was weak, they are consistent with observational data based on BMI phenotypes and suggest that the observed association between obesity and prostate cancer is not due to confounding. Further research should confirm these findings, extend them to other BMI-related genetic variants and determine whether they are due to detection bias or obesity-related hormonal changes.Controlled-Trials.com ISRCTN20141297.

    Full Text Available Family studies suggest a genetic component to the etiology of chronic kidney disease (CKD and end stage renal disease (ESRD. Previously, we identified 16 loci for eGFR in genome-wide association studies, but the associations of these single nucleotide polymorphisms (SNPs for incident CKD or ESRD are unknown. We thus investigated the association of these loci with incident CKD in 26,308 individuals of European ancestry free of CKD at baseline drawn from eight population-based cohorts followed for a median of 7.2 years (including 2,122 incident CKD cases defined as eGFR <60ml/min/1.73m(2 at follow-up and with ESRD in four case-control studies in subjects of European ancestry (3,775 cases, 4,577 controls. SNPs at 11 of the 16 loci (UMOD, PRKAG2, ANXA9, DAB2, SHROOM3, DACH1, STC1, SLC34A1, ALMS1/NAT8, UBE2Q2, and GCKR were associated with incident CKD; p-values ranged from p = 4.1e-9 in UMOD to p = 0.03 in GCKR. After adjusting for baseline eGFR, six of these loci remained significantly associated with incident CKD (UMOD, PRKAG2, ANXA9, DAB2, DACH1, and STC1. SNPs in UMOD (OR = 0.92, p = 0.04 and GCKR (OR = 0.93, p = 0.03 were nominally associated with ESRD. In summary, the majority of eGFR-related loci are either associated or show a strong trend towards association with incident CKD, but have modest associations with ESRD in individuals of European descent. Additional work is required to characterize the association of genetic determinants of CKD and ESRD at different stages of disease progression.

    Does a change in the nature of surrounding social context affect the strength of association between self-esteem and happiness? This paper aims to answer this question from a socio-ecological perspective, focusing on the role of relational mobility. Recent research has shown that this association is stronger in societies that are higher in relational mobility, where there is a greater freedom of choice in interpersonal relationships and group memberships. In this study, we tested if this hypothesis could be applied to situational differences within the same physical setting. Using a quasi-experimental design, we tested if the association between self-esteem and happiness was stronger for first-year students at a Japanese university who had just entered the college and thus were in a relatively higher mobility context, than the second-year students at the same university whose relationships tended to be more stable and long-standing. The results showed, as predicted, that the association between self-esteem and happiness was stronger for the first-year students than for the second-year students. Implications for the theory and research on social change are discussed.

    Food-related parenting behaviors have the potential to impact youth eating behaviors and nutrition knowledge. The present study examined associations between parental behaviors specific to eating (i.e., rules, solicitation, and the creation of a health-focused home environment) and specific unhealthy eating behaviors prevalent during adolescence. Additional analyses examined whether such associations were explained by adolescent nutrition knowledge. A total of 145 adolescents ( M = 14.48, SD = 1.75 years) and their mothers ( M = 43.52, SD = 6.76 years) completed questionnaires as part of a larger study investigating parent-adolescent communication. Mothers' food-related parenting behaviors were not directly associated with adolescents' engagement in unhealthy eating behaviors. However, more parental rules were associated with greater adolescent nutrition knowledge. In addition, mothers' creation of a health-focused home environment was indirectly associated with less fast food consumption through greater adolescent nutrition knowledge. Implications and future directions are discussed.

    The introduction of diagnostic criteria for vascular dementia has helped to re-define the impact of various subcortical neuropathologies on aging; however, state-of-the-art neuroimaging techniques and autopsy studies suggest that not all structural brain alterations associated with vascular dementia are exclusive to this neurodegenerative process alone. Thus, a detailed analysis of the cognitive phenotype associated with ischaemic vascular disease is key to our understanding of subcortical neuropathology and its associated behaviors. Over the past twenty years, we have operationally defined this cognitive phenotype using the Boston Process Approach to neuropsychological assessment. This has led to both an empirical, as well as a theoretical understanding of three core constructs related to the dysexecutive syndrome associated with ischaemic vascular disease affecting periventricular and deep white matter as well as subcortical structures connecting these regions with the prefrontal cortex. Thus, difficulties with mental set, cognitive control and mental manipulation negatively impact executive functioning. This review will outline the subtle markers underlying this prefrontal dysfunction, i.e., the dysexecutive phenotype, associated with ischaemic vascular disease and relate it to fundamental impairments of gating subserved by basal ganglia-thalamic pathways within and across various dementia syndromes.

    2016-01-01

    The relative age effect (RAE) is a well-established phenomenon in education and sports. Coaches have been assumed to be important social agents of RAE via biased selection decisions in favour of children with maturation advantages. In the present research, we used the Implicit Association Test to investigate automatic associations between body size and a player's domain-specific giftedness amongst youth baseball (N = 18) and youth soccer coaches (N = 34). We found medium to strong automatic associations between body size and player giftedness (baseball: MD = 0.62; soccer: MD = 0.51). Specifically, taller players were associated with positive performance-related attributes, whereas smaller players were associated with negative attributes. The results are in line with theories of grounded cognition by showing that the abstract concept of "sport giftedness" is partly grounded in the perception of physical height amongst youth sports coaches. We argue that this grounded cognition has the potential to influence coaches' selection decisions and in turn account for RAE as coaches are biased towards physically more matured players, even when no apparent performance advantage is evident.

    This study described herein explored the association of stressful life events with the utilization of substance use treatment-related services among substance users living in Puerto Rico. A secondary data analysis was conducted using data collected by a research project entitled Puerto Rico Drug Abuse Research Development Program II (PRDARDP II). The study population consisted of 378 individuals from 18 to 35 years of age who were residents of the San Juan metropolitan area and who presented evidence of substance use in the 30 days prior to the interview. The analysis considered demographic data, information on patterns of substance use, substance use treatment history, stressful events, and depression and anxiety symptomatology. As the number of stressful life events increased, substance users were more likely to report having utilized substance use treatment-related services (OR = 1.11, 95% CI [1.06, 1.17], p events associated with the utilization of substance use treatment-related services. Despite the structural limitations associated with access to and with the quality of the services in the substance use treatment-related system of Puerto Rico, findings suggest that stressful life events play a significant role in the utilization of those services. Researchers and clinicians should consider screening for stressful life events in outreach and engagement strategies. At the same time, the assessment of stressful life events should be integrated into the treatment planning stage to support the recovery process of people with substance use disorders.

    The importance of anger with regard to violence among veterans with combat-related PTSD has received little attention. We previously proposed that in PTSD the activation of threat-related cognitive networks strongly potentiates anger in a positive feedback loop and that inhibitory controls on aggression can be overridden when PTSD and anger activation are conjoined. We predicted that violence would be intensified when combat-related PTSD was conjoined with anger. We used the National Vietnam Veterans Readjustment Study (NVVRS) public use data set, selecting the male combat theater veterans, which entailed 1,200 from the main survey (Study 1) and 259 from the clinical interview component (Study 2). Anger indices were constructed from NVVRS variables. PTSD was assessed by continuous symptom scores and by clinical diagnostic measures. Conjoined anger and PTSD was associated with greatly increased violence. PTSD was not associated with violence in the absence of anger. This result was obtained using alternative measures of PTSD and of anger in both the main survey and the clinical interview component. These findings call for reconceptualizing the association of PTSD and violence. Concerted attention should be given to anger as a risk factor for violence in the assessment and treatment of combat-related PTSD, and as an important portal of entry for treatment.

    Research on factors associated with poor adherence to self-care focuses primarily on psychiatric emotional disorders such as depression and anxiety, whereas non-psychiatric chronic-disease-related emotional distress has received little attention in hypertensive patients. The objective of this study was to evaluate the association of hypertension-related distress with the lack of self-care including low adherence to pharmacological treatment, lack of regular physical activity, low intake of fruits and vegetables and frequent intake of high-salt foods. A cross-sectional survey was conducted in 2014 in two family medical units affiliated with the Mexican Institute of Social Security. The study included 487 hypertensive patients >19 years of age. The conceptual framework for the study was based on the Health Promotion Model. The analysis included multiple Poisson regression models. We found that 21.1% of participants had hypertension-related distress. Low adherence to pharmacological treatment was identified in 45.8% of patients, whereas 46.8% lacked regular physical activity, 30.8% reported a low consumption of fruits and vegetables, and 54.6% frequently consumed foods high in salt content. Hypertension-related distress was associated with lack of regular physical activity and low intake of fruits and vegetables. These findings highlight the importance of addressing distress in order to improve self-care of hypertensive patients.

    Theory suggests that aversive social experiences generate emotional maladjustment because they prompt the development of a hypersensitivity to perceiving and overreacting to rejection. The primary aim of this study was to test hypothesized direct and indirect (via rejection sensitivity) links of overt/relational victimization and friendship conflict with early adolescents' loneliness and depressive symptoms. Participants were 366 Australian early adolescents age 10-14 years (50.5 % girls). Using both a self-report and peer-report measure of rejection sensitivity, no difference was found when comparing the significant correlations of each measure with loneliness and depressive symptoms. Tests of direct and indirect associations with structural equation modeling showed that adolescents higher in relational victimization reported more loneliness and depressive symptoms and part of this association was by way of their greater self-reports of rejection sensitivity and their peers' identification that they were higher in rejection sensitivity. Additionally, relational victimization was the only unique correlate of emotional maladjustment, and adolescents who reported more overt victimization were identified by their peers as higher in rejection sensitivity. Finally, gender and rejection sensitivity were tested as moderators. No gender moderation was found, but friendship conflict was associated more strongly with emotional maladjustment for adolescents low, rather than high, in rejection sensitivity. These findings identify relational victimization as particularly salient for emotional maladjustment both directly and indirectly via links with elevated rejection sensitivity. They show how rejection sensitivity and aversive experiences may contribute independently and jointly to emotional maladjustment for both boys and girls.

  11. Is Work-Related Rumination Associated with Deficits in Executive Functioning?

    Work-related rumination, that is, perseverative thinking about work during leisure time, has been associated with a range of negative health and wellbeing issues. The present paper examined the association between work-related rumination and cognitive processes centerd around the theoretical construct of executive functioning. Executive functioning is an umbrella term for high level cognitive processes such as planning, working memory, inhibition, mental flexibility; and it underlies how people manage and regulate their goal directed behavior. Three studies are reported. Study I, reports the results of a cross-sectional study of 240 employees, and demonstrates significant correlations between work-related rumination and three proxy measures of executive functioning: cognitive failures (0.33), cognitive flexibility (-0.24), and situational awareness at work (-0.28). Study II (n = 939), expands on the findings from study 1 and demonstrates that workers reporting medium and high work-related rumination were 2.8 and 5 times, respectively, more likely to report cognitive failures relative to low ruminators. High ruminators also demonstrated greater difficulties with 'lapses of attention' (OR = 4.8), 'lack of focus of attention' (OR = 3.4), and 'absent mindedness' (OR = 4.3). The final study, examined the association between work-related rumination and executive functioning using interview data from 2460 full time workers. Workers were divided into tertiles low, medium, and high. The findings showed that high work-related rumination was associated with deficits in starting (OR = 2.3) and finishing projects (OR = 2.4), fidgeting (OR = 1.9), memory (OR = 2.2), pursuing tasks in order (OR = 1.8), and feeling compelled to do things (OR = 2.0). It was argued that work-related rumination may not be related to work demands per se, but appears to be an executive functioning/control issue. Such findings are important for the design and delivery of intervention programes aimed at

    Neighborhood safety is important for older adults' health and wellbeing, but there has not been a synthesis in the literature of what is currently known about this construct. This systematic literature review, following the PRISMA guidelines, focuses on identifying neighborhood safety factors associated with health-related outcomes and behaviors of older adults in the U.S. A search was conducted in 2014 via Academic Search Complete, CINAHL, Embase, MEDLINE, SportDis, and Transportation Databases. Based on our inclusion and exclusion criteria, we identified thirty-two articles for review. Sixteen studies examined health outcomes such as health status, mental health, physical function, morbidity/mortality, and obesity; the other sixteen studies focused on health behaviors, such as physical activity and walking. Four domains of neighborhood safety were identified: overall/general neighborhood safety; crime-related safety; traffic-related safety; and proxies for safety (e.g., vandalism, graffiti). Overall/general neighborhood safety appeared most relevant to mental health and physical function. Traffic-related safety was most pertinent to physical activity, while crime-related safety was more consistently associated with mental health and walking. While all safety variables were significantly associated with mental health, no significant associations were found for obesity. We also found that specific measures or constructs of safety were not applied consistently across the examined studies, making it difficult to compare the results. This review identified several important gaps in the existing studies dealing with neighborhood safety-health relationships among older adults. Further studies are needed that examine the different roles of multidimensional neighborhood safety in promoting the community health, not only in the U.S., but globally.

    To examine the associations between weight status and structural and functional dimensions of social relations among 11- to 15-year-old girls and boys. Analyses were based on cross-sectional data from the Danish contribution to the international Health Behavior in School-aged Children study 2010. The study population (n = 4,922) included students in the fifth, seventh, and ninth grade from a representative sample of Danish schools. Multinomial logistic regression analyses were used to study the associations between weight status and social relations, supported by a conceptual framework for the study of social relations. Among girls, overweight/obese weight status was associated with spending less time with friends after school compared to normal-weight status (0 days/week: odds ratio: 6.25, 95% confidence interval: 2.18-17.95, 1 day/week: 2.81, 1.02-7.77, 2 days/week: 3.27, 1.25-8.56, 3 days/week: 3.32, 1.28-8.61, and 4 days/week: 3.23, 1.17-8.92, respectively vs. 5 days/week). Among girls, overweight/obese weight status was associated with being bullied (2.62, 1.55-4.43). Among boys, overweight/obese weight status was associated with infrequent (1 to 2 days vs. every day) communication with friends through cellphones, SMS messages, or Internet (1.66, 1.03-2.67). In the full population, overweight/obese weight status was associated with not perceiving best friend as a confidant (1.59, 1.11-2.28). No associations were found between weight status and number of close same-sex and opposite-sex friends, mother/father as confidant, and perceived classmate acceptance. This study shows that overweight/obese adolescents have higher odds of numerous poor social relations than their normal-weight peers both in terms of structural and functional dimensions of social relations.

    Sleep duration is known to be associated with depression and attention deficits in children, though the majority of studies have focused on adolescents. Attention problems and depressive symptoms related to sleep factors have not been studied simultaneously in the non-clinical child population before. Sleep quantity, adverse bedtime behaviour, daytime sleepiness, poor attention and symptoms of depression were assessed using self-report measures. The participants were 11 years old (n = 439). Short sleep duration during the school week is related to poor attention and high depression. It is not a significant predictor of low attention and high depression symptoms in logistic regression analyses. Instead, adverse bedtime behaviour and daytime sleepiness predict them highly significantly. Short sleep duration is related to poor attention and depressive symptoms as suggested by previous work. However, the significant role of other sleep-related factors calls for further research. © 2013 John Wiley & Sons Ltd.

    BACKGROUND: Approximately 30-40% of heart patients develop anxiety and/or depression, which might influence recovery and long-term survival. Research has suggested that support from relatives may decrease anxiety and depression among heart patients; however, the results are inconsistent and often...... based on small study populations. AIM: The paper aimed to investigate the association between having supportive relatives and the occurrence of anxiety and depression in heart patients. METHODS: A population-based cross-sectional study among Danish patients diagnosed with ischemic heart disease, atrial...... fibrillation, heart failure, or heart valve disease. Presence of supportive relatives was measured as the degree to which the patients felt that they had relatives they could count on, while symptoms of anxiety and depression were measured by the Hospital Anxiety and Depression Scale (HADS).

    Although cannabis abuse (CA) is known to be associated with schizophrenia, the causal nature of this association is unclear, with prodromal effects complicating its interpretation. From Swedish national registry databases, we used a co-relative case-control design with full-sibling, half-sibling and first-cousin comparisons, alongside a general Swedish population sample. Using ICD codes, 5456 individuals with an initial diagnosis of schizophrenia (2000-2010) were matched with five schizophrenia-free controls. We further identified first-cousin, half-sibling and full-sibling pairs discordant for CA and statistically extrapolated results for discordant monozygotic (MZ) twins. Within the general Swedish population, CA was strongly associated with later schizophrenia [odds ratio (OR) 10.44, 95% confidence interval (CI) 8.99-12.11]. This association was substantially attenuated both by increasing temporal delays between CA exposure and schizophrenia diagnosis and by controlling for increasing degrees of familial confounding. Extrapolated discordant MZ pairs suggested that fully controlling for confounding familial factors reduced the association between CA and later schizophrenia to more modest levels (ORs of approximately 3.3 and 1.6 with 3- and 7-year temporal delays respectively). Opiate, sedative, cocaine/stimulant and hallucinogen abuse were also strongly associated with subsequent schizophrenia in the general population. After controlling for familial confounding, only cocaine/stimulant exposure remained associated. CA has an appreciable causal impact on future risk for schizophrenia. However, population-based estimates of cannabis-schizophrenia co-morbidity substantially overestimate their causal association. Predictions of the cases of schizophrenia that might be prevented by reduced cannabis consumption based on population associations are therefore likely to be considerably overestimated.

    To identify genetic loci associated with features of histologic severity of nonalcoholic fatty liver disease in a cohort of Hispanic boys. There were 234 eligible Hispanic boys age 2-17 years with clinical, laboratory, and histologic data enrolled in the Nonalcoholic Steatohepatitis Clinical Research Network included in the analysis of 624 297 single nucleotide polymorphisms (SNPs). After the elimination of 4 outliers and 22 boys with cryptic relatedness, association analyses were performed on 208 DNA samples with corresponding liver histology. Logistic regression analyses were carried out for qualitative traits and linear regression analyses were applied for quantitative traits. The median age and body mass index z-score were 12.0 years (IQR, 11.0-14.0) and 2.4 (IQR, 2.1-2.6), respectively. The nonalcoholic fatty liver disease activity score (scores 1-4 vs 5-8) was associated with SNP rs11166927 on chromosome 8 in the TRAPPC9 region (P = 8.7 -07 ). Fibrosis stage was associated with SNP rs6128907 on chromosome 20, near actin related protein 5 homolog (p = 9.9 -07 ). In comparing our results in Hispanic boys with those of previously reported SNPs in adult nonalcoholic steatohepatitis, 2 of 26 susceptibility loci were associated with nonalcoholic fatty liver disease activity score and 2 were associated with fibrosis stage. In this discovery genome-wide association study, we found significant novel gene effects on histologic traits associated with nonalcoholic fatty liver disease activity score and fibrosis that are distinct from those previously recognized by adult nonalcoholic fatty liver disease genome-wide association studies.

    Residual feed intake (RFI), a measure of feed efficiency, is the difference between observed feed intake and the expected feed requirement predicted from growth and maintenance. Pigs with low RFI have reduced feed costs without compromising their growth. Identification of genes or genetic markers associated with RFI will be useful for marker-assisted selection at an early age of animals with improved feed efficiency. Whole genome association studies (WGAS) for RFI, average daily feed intake (ADFI), average daily gain (ADG), back fat (BF) and loin muscle area (LMA) were performed on 1,400 pigs from the divergently selected ISU-RFI lines, using the Illumina PorcineSNP60 BeadChip. Various statistical methods were applied to find SNPs and genomic regions associated with the traits, including a Bayesian approach using GenSel software, and frequentist approaches such as allele frequency differences between lines, single SNP and haplotype analyses using PLINK software. Single SNP and haplotype analyses showed no significant associations (except for LMA) after genomic control and FDR. Bayesian analyses found at least 2 associations for each trait at a false positive probability of 0.5. At generation 8, the RFI selection lines mainly differed in allele frequencies for SNPs near (energy homeostasis (e.g., MC4R, PGM1, GPR81) and muscle growth related genes (e.g., TGFB1) with ADG, and of fat metabolism genes (e.g., ACOXL, AEBP1) with BF. Specifically, a very highly significantly associated QTL for LMA on SSC7 with skeletal myogenesis genes (e.g., KLHL31) was identified for subsequent fine mapping. Important genomic regions associated with RFI related traits were identified for future validation studies prior to their incorporation in marker-assisted selection programs.

    The need for studies from more countries on the relationship between urban green space and health has been emphasized. The aim of this study was to investigate the association between two types of measurement of urban green space and self-reported lifestyle-related disorders in Oslo, Norway. Self-reported measures on mental disorders, asthma, type 2 diabetes and musculoskeletal pain of 8638 participants in the Oslo Health Study (HUBRO) were linked to two types of green space variables: the vegetation cover greenness derived from satellite data, which shows the city's vegetation cover regardless of property boundaries, and the land use greenness derived from municipal plans showing information about publicly accessible vegetation-covered areas. Associations between greenness and health measures were analysed by logistic regression models controlling for possible individual and contextual confounders. Increasing vegetation cover greenness was associated with fewer self-reported mental disorders for both men and women after controlling for possible confounders. The proportion of women who reported high levels of musculoskeletal pain increased with increasing degrees of both of the greenness measurements, but no significant association was observed for men. No association was found for asthma and diabetes type 2 for either men or women. Although there was a positive association between vegetation cover greenness and self-reported mental disorders, the main findings showed mixed results. The lack of clear associations between urban green space and lifestyle-related health disorders in Oslo might have been influenced by a large proportion of the inhabitants having easy access to green areas.

    (6)/l, P less than 0.05), and more often a history of previous AIDS-defining illnesses (50% vs. 0%, P less than 0.005), compared with patients with Burkitt-type lymphomas. Epstein-Barr virus (EBV) DNA was demonstrated in 14 of 19 immunoblast-rich tumours, and in 2 of 7 Burkitt-type lymphomas (P = 0.......10). Compared with EBV DNA-negative tumours EBV DNA-positive tumours were associated with lower CD4 cell counts (median 39 vs. 188 x 10(6)/l, P = 0.01). It is concluded that two main types of HIV-related malignant lymphoma exist. One is associated with severe immunosuppression, is often of immunoblast......-rich morphology, and may be linked to EBV, whereas the other may occur in the absence of immunosuppression, is often of Burkitt-type morphology, and is probably not linked to EBV. In addition to these two main types, other non-Hodgkin lymphomas and Hodgkin's disease do occur....

    The aim of this research was to examine the association between body mass index, physical activity, adherence to the Mediterranean diet, and health-related quality of life in a sample of Spanish adolescents. The study involved 456 adolescents aged between 11 and 14 years. They completed questionnaires on the Mediterranean diet (KIDMED), physical activity (Physical Activity Questionnaire for Older Children [PAQ-C]), and quality of life (KIDSCREEN-27). Body mass index was calculated. Hierarchical linear regression analyses were used to determine whether health-related quality of life could be predicted by the measured variables. The variables were analyzed in a stepwise manner, with Mediterranean diet entered in the first step, body mass index in the second, and physical activity in the third. Mediterranean diet accounted for 4.6% of the variance in adolescent's health-related quality of life, with higher adherence to the Mediterranean diet predicting higher health-related quality of life-scores. Body mass index accounted for a further 4.1% of the variance, with a higher body mass index predicting lower health-related quality of life scores. Finally, physical activity explained an additional 11.3% of the variance, with a higher level of physical activity being associated with higher health-related quality of life scores. Together, these variables explained 20% of the variance in the adolescents' health-related quality of life. Physical activity, body mass index, and adherence to the Mediterranean diet are important components to consider when targeting improvements in the health-related quality of life of adolescents, with physical activity representing the component with the greatest influence.

    OBJECTIVE To identify risk factors for anesthetic-related death in pet dogs and cats. DESIGN Matched case-control study. ANIMALS 237 dogs and 181 cats. PROCEDURES Electronic medical records from 822 hospitals were examined to identify dogs and cats that underwent general anesthesia (including sedation) or sedation alone and had death attributable to the anesthetic episode ≤ 7 days later (case animals; 115 dogs and 89 cats) or survived > 7 days afterward (control animals [matched by species and hospital]; 122 dogs and 92 cats). Information on patient characteristics and data related to the anesthesia session were extracted. Conditional multivariable logistic regression was performed to identify factors associated with anesthetic-related death for each species. RESULTS The anesthetic-related death rate was higher for cats (11/10,000 anesthetic episodes [0.11%]) than for dogs (5/10,000 anesthetic episodes [0.05%]). Increasing age was associated with increased odds of death for both species, as was undergoing nonelective (vs elective) procedures. Odds of death for dogs were significantly greater when preanesthetic physical examination results were not recorded (vs recorded) or when preanesthetic Hct was outside (vs within) the reference range. Odds of death for cats were greater when intra-anesthesia records for oxygen saturation as measured by pulse oximetry were absent. Underweight dogs had almost 15 times the odds of death as nonunderweight dogs; for cats, odds of death increased with increasing body weight (but not with overweight body condition). CONCLUSIONS AND CLINICAL RELEVANCE Several factors were associated with anesthetic-related death in cats and dogs. This information may be useful for development of strategies to reduce anesthetic-related risks when possible and for education of pet owners about anesthetic risks.

    Design and analysis methods are presented for studying the association of a candidate gene with a disease by using parental data in place of nonrelated controls. This alternating design eliminates spurious differences in allele frequencies between cases and nonrelated controls resulting from different ethnic origins and population stratification for these two groups. The authors present analysis methods which are based on two genetic relative risks: (1) the relative risk of disease for homozygotes with two copies of the candidate gene versus homozygotes without the candidate gene and (2) the relative risk for heterozygotes with one copy of the candidate gene versus homozygotes without the candidate gene. In addition to estimating the magnitude of these relative risks, likelihood methods allow specific hypotheses to be tested, namely, a test for overall association of the candidate gene with disease, as well as specific genetic hypotheses, such as dominant or recessive inheritance. Two likelihood methods are presented: (1) a likelihood method appropriate when Hardy-Weinberg equilibrium holds and (2) a likelihood method in which the authors condition on parental genotype data when Hardy-Weinberg equilibrium does not hold. The results for the relative efficiency of these two methods suggest that the conditional approach may at times be preferable, even when equilibrium holds. Sample-size and power calculations are presented for a multitiered design. Tier 1 detects the presence of an abnormal sequence for a postulated candidate gene among a small group of cases. Tier 2 tests for association of the abnormal variant with disease, such as by the likelihood methods presented. Tier 3 confirms positive results from tier 2. Results indicate that required sample sizes are smaller when expression of disease is recessive, rather than dominant, and that, for recessive disease and large relative risks, necessary sample sizes may be feasible. 19 refs., 2 figs., 2 tabs.

    Full Text Available In this study, data from the World Mental Health Survey's Northern Ireland (NI Study of Health and Stress (NISHS was used to assess the associations between conflict- and non-conflict-related traumatic events and suicidal behaviour, controlling for age and gender and the effects of mental disorders in NI. DSM mental disorders and suicidal ideation, plans and attempts were assessed using the Composite International Diagnostic Interview (CIDI in a multi-stage, clustered area probability household sample (N = 4,340, response rate 68.4%. The traumatic event categories were based on event types listed in the PTSD section of the CIDI. Suicidal ideation and attempts were more common in women than men, however, rates of suicide plans were similar for both genders. People with mood, anxiety and substance disorders were significantly more likely than those without to endorse suicidal ideation, plan or attempt. The highest odds ratios for all suicidal behaviors were for people with any mental disorder. However, the odds of seriously considering suicide were significantly higher for people with conflict and non-conflict-related traumatic events compared with people who had not experienced a traumatic event. The odds of having a suicide plan remain significantly higher for people with conflict-related traumatic events compared to those with only non-conflict-related events and no traumatic events. Finally, the odds of suicide attempt were significantly higher for people who have only non-conflict-related traumatic events compared with the other two categories. The results suggest that traumatic events associated with the NI conflict may be associated with suicidal ideation and plans, and this effect appears to be in addition to that explained by the presence of mental disorders. The reduced rates of suicide attempts among people who have had a conflict-related traumatic event may reflect a higher rate of single, fatal suicide attempts in this population.

    Cognitive deficits, especially in memory and concentration, are often reported during pregnancy. Similar cognitive dysfunctions can also occur in depression and anxiety. To date, few studies have investigated the associations between cognitive deficits and psychiatric symptoms during pregnancy. This field is of interest because maternal cognitive functioning, and particularly its higher-order aspects are related to maternal well-being and caregiving behavior, as well as later child development. Pregnant women (N =230), reporting low (n =87), moderate (n =97), or high (n =46) levels of depressive, general anxiety and/or pregnancy-related anxiety symptoms (assessed repeatedly with EPDS, SCL-90/anxiety subscale, PRAQ-R2, respectively) were tested in mid-pregnancy for their cognitive functions. A computerized neuropsychological test battery was used. Pregnant women with high or moderate level of psychiatric symptoms had significantly more errors in visuospatial working memory/executive functioning task than mothers with low symptom level. Depressive symptoms throughout pregnancy and concurrent pregnancy-related anxiety symptoms were significant predictors of the performance in the task. General anxiety symptoms were not related to visuospatial working memory. Cognitive functions were evaluated only at one time-point during pregnancy precluding causal conclusions. Maternal depressive symptoms and pregnancy-related anxiety symptoms were both associated with decrements in visuospatial working memory/executive functioning. Depressive symptoms seem to present more stable relationship with cognitive deficits, while pregnancy-related anxiety was associated only concurrently. Future studies could investigate, how stable these cognitive differences are, and whether they affect maternal ability to deal with demands of pregnancy and later parenting.

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

    Crick, Murray-Close, and Woods (2005) encouraged the study of relational aggression as a developmental precursor to borderline personality features in children and adolescents. A longitudinal study is needed to more fully explore this association, to contrast potential associations with physical aggression, and to assess generalizability across various cultural contexts. In addition, parenting is of particular interest in the prediction of aggression or borderline personality disorder. Early aggression and parenting experiences may differ in their long-term prediction of aggression or borderline features, which may have important implications for early intervention. The currrent study incorporated a longitudinal sample of preschool children (84 boys, 84 girls) living in intact, two-parent biological households in Voronezh, Russia. Teachers provided ratings of children's relational and physical aggression in preschool. Mothers and fathers also self-reported their engagement in authoritative, authoritarian, permissive, and psychological controlling forms of parenting with their preschooler. A decade later, 70.8% of the original child participants consented to a follow-up study in which they completed self-reports of relational and physical aggression and borderline personality features. The multivariate results of this study showed that preschool relational aggression in girls predicted adolescent relational aggression. Preschool aversive parenting (i.e., authoritarian, permissive, and psychologically controlling forms) significantly predicted aggression and borderline features in adolescent females. For adolescent males, preschool authoritative parenting served as a protective factor against aggression and borderline features, whereas authoritarian parenting was a risk factor for later aggression.

    Climatic models and predictions indicate increase in aridity world over due to global warming. Arid environments occupy about one third land area of the world. A. senegal is the most important dryland resource of western Rajasthan desert ecosystem. The seeds of 13 low and high seed yielding exotic and indigenous provenances were evaluated for diversity and interrelationship among growth related seedling traits targeting establishment and end use of this species. Under the present study most of the growth related seedling traits varied within and amongst provenances. Highly significant correlation of dry biomass per plant of more than 72% with root length (73.3%), collar diameter (72.2%), shoot dryweight (99.7%), root dry weight (95.7%) and seedling length (79.9%) under the present study may be used for early selection. Similarly, highly significant positive correlation of seedling length with seven out of 12 growth related seedling traits validate strong inherent association of these traits under strong genetic control and are amenable for selection. Significant negative correlation in number of nodules per plant with root/shoot length ratio (-57.6%) and no correlation with 10 out of 12 growth related seedling traits tested advocate emphasis on other growth related seedling traits in selection of elite A. senegal genotypes for afforestation. The non significant associations suggest that per cent germination was independent of other characters and could be selected separately.

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

    Full Text Available Abstract Background Amount of sleep is an important indicator of health and well-being in children and adolescents. Adequate sleep (AS: adequate sleep is defined as 6–8 hours per night regularly is a critical factor in adolescent health and health-related behaviors. The present study was based on a health promotion project previously conducted on adolescents in Tao-Yuan County, Taiwan. The aim was to examine the relationship between AS during schooldays and excessive body weight, frequency of visiting doctors and health-related behaviors among Taiwanese adolescents. Methods A cross-sectional study design, categorical and multivariate data analyses were used. The hypotheses investigated were: high frequency of AS is positively associated with lack of obesity and less frequent visits to doctors; and high frequency AS is positively associated with health-related behavior. Results A total of 656 boys (53.2% and girls (46.8%, ranging in age from 13–18 years were studied between January and June 2004. Three hundred and fifty seven subjects (54% reported that they slept less than the suggested 6–8 hours on schooldays. A significant negative association was found between low sleep and of the following health-related behaviors: (1 life appreciation; (2 taking responsibility for health; (3 adopting healthy diet; (4 effective stress management; (5 regular exercise; and (6 total AHP score. High frequency AS was associated with low frequencies of obesity after potential confounding factors were controlled. Junior high school adolescents reported significantly higher frequencies of AS than high school participants. Gender, family structure, home location and frequency of television watching or computer use were not significantly associated with AS. Conclusion These findings support the proposition that AS is associated with good health status and high-frequency adoption of health-related behavior. Furthermore, these findings suggest that inadequate

    An association between coronary heart disease (CHD) and age-related macular degeneration (AMD) has long been postulated but results from epidemiological case-control studies, and genetic analyses have been ambiguous. In this study we illuminate the association between AMD and CHD with respect to genetic and environmental risk factors, age of disease onset and AMD subgroups. AMD patients (n = 1036) and age-matched control subjects (n = 412) between 68 and 95 years of age were included in the case-control study. A medical history of CHD, cerebral stroke and arterial hypertension was determined for each individual. The assessment of interacting factors included the current use of systemic medications and smoking habits. Analysis of AMD associated genetic variants included frequent polymorphisms at the complement factor H (CFH, MIM 134370) gene (rs1061170 [p.Y402H], rs800292 [p.I62V]), the complement factor H-related 3 (CFHR3, MIM 605336)/complement factor H-related 1 (CFHR1, MIM 134371) locus (rs6677604; proxy for ΔCFHR3/CFHR1; r(2) = 0.97) as well as the age-related maculopathy susceptibility 2 (ARMS2, MIM 611313) gene (rs10490924 [p.A69S]). Logistic regression identified a significant positive association of AMD with AMD-risk variants in CFH, ARMS2, and smoking ≥ 20 packs/year. A history of CHD and the current use of antihyperuricemic agents were inversely associated with the disease. Significantly fewer patients with rs6677604 nonrisk genotype A/A regularly used statins. ARMS2:p.A69S risk variant was significantly associated with exsudative AMD. AMD patients with risk variants at rs1061170 (CFH:p.Y402H) and ARMS2 and smokers (≥20 packs/year) were significantly earlier affected by AMD than those carrying the non-risk variants at each locus. Our data support three major conclusions. First, the age of AMD onset is significantly influenced by genetic and environmental risk factors. Second, in support of previous reports we also show that the ARMS2 rs10490924:T

    Emerging literature suggests that lifestyle factors may play an important role in reducing age-related cognitive decline. There have, however, been few studies investigating the role of cognitively stimulating leisure activities in maintaining cognitive health. This study sought to identify changes in cognitive performance with age and to investigate associations of cognitive performance with several key cognitively stimulating leisure activities. Over 65,000 participants provided demographic and lifestyle information and completed tests of grammatical reasoning, spatial working memory, verbal working memory and episodic memory. Regression analyses suggested that frequency of engaging in Sudoku or similar puzzles was significantly positively associated with grammatical reasoning, spatial working memory and episodic memory scores. Furthermore, for participants aged under 65 years, frequency of playing non-cognitive training computer games was also positively associated with performance in the same cognitive domains. The results also suggest that grammatical reasoning and episodic memory are particularly vulnerable to age-related decline. Further investigation to determine the potential benefits of participating in Sudoku puzzles and non-cognitive computer games is indicated, particularly as they are associated with grammatical reasoning and episodic memory, cognitive domains found to be strongly associated with age-related cognitive decline. Results of this study have implications for developing improved guidance for the public regarding the potential value of cognitively stimulating leisure activities. The results also suggest that grammatical reasoning and episodic memory should be targeted in developing appropriate outcome measures to assess efficacy of future interventions, and in developing cognitive training programmes to prevent or delay cognitive decline.

    2012-07-01

    Many genes have been implicated in the pathogenesis of common respiratory and related diseases (RRDs), yet the underlying mechanisms are largely unknown. Differential gene expression patterns in diseased and healthy individuals suggest that RRDs affect or are affected by modified transcription regulation programs. It is thus crucial to characterize implicated genes in terms of transcriptional regulation. For this purpose, we conducted a promoter analysis of genes associated with 11 common RRDs including allergic rhinitis, asthma, bronchiectasis, bronchiolitis, bronchitis, chronic obstructive pulmonary disease, cystic fibrosis, emphysema, eczema, psoriasis, and urticaria, many of which are thought to be genetically related. The objective of the present study was to obtain deeper insight into the transcriptional regulation of these disease-associated genes by annotating their promoter regions with transcription factors (TFs) and TF binding sites (TFBSs). We discovered many TFs that are significantly enriched in the target disease groups including associations that have been documented in the literature. We also identified a number of putative TFs/TFBSs that appear to be novel. The results of our analysis are provided in an online database that is freely accessible to researchers at http://www.respiratorygenomics.com. Promoter-associated TFBS information and related genomic features, such as histone modification sites, microsatellites, CpG islands, and SNPs, are graphically summarized in the database. Users can compare and contrast underlying mechanisms of specific RRDs relative to candidate genes, TFs, gene ontology terms, micro-RNAs, and biological pathways for the conduct of metaanalyses. This database represents a novel, useful resource for RRD researchers. Copyright © 2012 by the American Thoracic Society.

    High-potency cannabis concentrates are increasingly popular in the United States, and there is concern that use of high-potency cannabis might increase risk for cannabis-related problems. However, little is known about the potential negative consequences of concentrate use. This study reports on associations between past-year use of a high-potency cannabis concentrate, known as butane hash oil (BHO), and cannabis-related problems. A sample of 821 college students were recruited to complete a survey about their health and behavior. Participants who had used cannabis in the past year (33%, n=273) completed questions about their cannabis use, including their use of BHO and cannabis-related problems in eight domains: physical dependence, impaired control, academic-occupational problems, social-interpersonal problems, self-care problems, self-perception, risk behavior, and blackouts. Approximately 44% (n=121) of past-year cannabis users had used BHO in the past year. More frequent BHO use was associated with higher levels of physical dependence (RR=1.8, pacademic/occupational problems (RR=1.5, p=0.004), poor self-care (RR=1.3, p=0.002), and cannabis-related risk behavior (RR=1.2, p=0.001). After accounting for sociodemographic factors, age of onset of cannabis use, sensation seeking, overall frequency of cannabis use, and frequency of other substance use, BHO use was still associated with higher levels of physical dependence (RR=1.2, p=0.014). BHO use is associated with greater physiological dependence on cannabis, even after accounting for potential confounders. Longitudinal research is needed to determine if cannabis users with higher levels of physiological dependence seek out BHO and/or if BHO use increases risk for physiological dependence.

    Research suggests that a cancer diagnosis predicts marital dissolution more strongly for women survivors than men, but there is a paucity of research on potential processes underlying this vulnerability. The present cross-sectional study examined whether specific cancer-related problems were associated with the odds of relationship breakup following diagnosis and whether these relationships differed between male and female cancer survivors. A national cross-sectional quality of life study assessed self-reported cancer-related problems and relationship change among survivors who were either 2, 6, or 10 years post-diagnosis (n = 6099). Bivariate analyses indicated that cancer-related problems (e.g., emotional distress) were greater for divorced/separated survivors compared to those with intact relationships and were greater for women versus men. Logistic regressions indicated that for both male and female survivors, lower income, younger age, and longer time since diagnosis were associated with greater odds of divorce or separation after diagnosis (ORs > 2.14, p emotional distress (OR = 1.14, p separation. For men only, fear of cancer recurrence was associated with greater odds of divorce or separation (OR = 1.32, p emotional or financial/employment problems attributed to the cancer diagnosis were associated with the likelihood of reporting relationship dissolution. Although directions of causality could not be ascertained, results suggest the possibility that helping male and female cancer survivors cope with specific cancer-related problems may benefit the quality and stability of their relationships with significant others following diagnosis.

    To compare baseline kinesiophobia levels and their association with health-related quality of life across injury locations. Retrospective cross-sectional study. Single, large outpatient physical therapy clinic within an academic medical center. Patients (N=1233) who underwent an initial evaluation for a diagnosis related to musculoskeletal pain and completed the 11-item version of the Tampa Scale for Kinesiophobia (TSK-11) and the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8) questionnaires within 7 days of their first visit were eligible for inclusion. Three hundred eighty patients were excluded because of missing data or because they were younger than 18 years. A total of 853 patients (mean age, 43.55y; range, 18-94y) were included. Not applicable. Comparison of baseline kinesiophobia levels and their association with health-related quality of life across injury locations in an outpatient physical therapy setting. Separate analysis of variance models compared TSK-11 scores based on involved body region, and Pearson correlation coefficients were used to examine the association between TSK-11 scores and the SF-8 subscales at each body region. TSK-11 scores did not differ by body region (range, 23.9-26.1). Weak to moderate negative correlations existed between kinesiophobia and the SF-8 subscales. Kinesiophobia levels appear elevated and negatively associated with health-related quality of life at initial physical therapy evaluation regardless of injury location. These findings suggest that physical therapists in outpatient orthopedic settings should implement routine kinesiophobia assessment and provide stratified care based on kinesiophobia levels across musculoskeletal conditions.

    Childhood abuse is associated with increased risks of adult psychiatric disorders and physical health conditions. Mounting evidence documents associations of childhood abuse with sleep disturbances in adulthood. However, to date, no study has evaluated associations of childhood abuse and sleep disturbances among pregnant women. This cross-sectional study included 634 pregnant Peruvian women. To collect information regarding socio-demographic characteristics, history of childhood abuse, and complaints of sleep disturbances, face-to-face interviews were conducted with women in early pregnancy. Ford Insomnia Response to Stress Test (FIRST-S) and the Pittsburgh Sleep Quality Index (PSQI-S), translated from English to Spanish, were used to assess stress-related sleep disturbance and sleep quality, respectively. Logistic regression was used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95% CIs). Women who experienced any childhood abuse had a 1.65-fold increased odds of stress-related sleep disturbance (aOR = 1.65; 95% CI: 1.15-2.38) and 2.11-fold increased odds of poor sleep quality during early pregnancy (aOR = 2.11; 95% CI: 1.35-3.30) as compared with women who reported no abuse. Women who reported both physical and sexual abuse during childhood were more than twice as likely to suffer from stress-related sleep disturbance (aOR = 2.26; 95% CI: 1.44-3.53) and poor sleep quality (aOR = 2.43; 95% CI: 1.45-4.09) in comparison to women who reported no childhood abuse. A history of childhood abuse is associated with increased odds of stress-related sleep disturbance and poor sleep quality during pregnancy. These findings, if replicated, should be used to inform the development of trauma-informed care for such sleep disturbances induced by childhood trauma. Copyright © 2015 Elsevier B.V.

    The aim of this study is to assess the quality of life (QoL), family burden and psychiatric disorders in first-degree relatives of patients with obsessive-compulsive disorder (OCD) and to compare them with healthy controls and their relatives. Forty patients with OCD and 47 of their first-degree relatives as well as 40 healthy subjects and 45 of their first-degree relatives were recruited in this study. OCD and comorbid anxiety or mood disorders were determined by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders. Comorbid Axis II disorders were diagnosed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition Personality Disorders. Type and severity of obsessive-compulsive symptoms were assessed with the Yale-Brown Obsessive-Compulsive Scale, and the disability of patients with OCD was evaluated with the WHO DAS II. Family burden and QoL in the relatives were evaluated with the Zarit Burden Interview (ZBI) protocol and the World Health Organization Quality of Life Assessment-Brief, respectively. The mean ZBI score of family members of OCD patients was higher than the control relatives. Linear regression analysis indicated that the independent factors associated with ZBI were duration of OCD, comorbid major depressive disorder and poorer insight. Compared with those of control relatives, the QoL of relatives of patients with OCD was significantly lower in all domains. While the diagnosis of major depressive disorder in relatives of OCD patients was significantly higher than the control relatives, the diagnosis of any anxiety disorder did not differ. Our study provides evidence that OCD not only affects the lives of patients but also their family members. Copyright © 2013 Elsevier Inc. All rights reserved.

    Trauma-associated injuries of the thorax and abdomen account for the majority of combat trauma-associated deaths, and infectious complications are common in those who survive the initial injury. This review focuses on the initial surgical and medical management of torso injuries intended to diminish the occurrence of infection. The evidence for recommendations is drawn from published military and civilian data in case reports, clinical trials, meta-analyses, and previously published guidelines, in the interval since publication of the 2008 guidelines. The emphasis of these recommendations is on actions that can be taken in the forward-deployed setting within hours to days of injury. This evidence-based medicine review was produced to support the Guidelines for the Prevention of Infections Associated With Combat-Related Injuries: 2011 Update contained in this supplement of Journal of Trauma.

    Full Text Available Objective: To describe associations between health care utilization measures and patient-reported outcomes (PROs. Method: Primary data were collected from patients ≥65 years with low back pain visits from 2011 to 2013. Six PROs of pain and functionality were collected 12 and 24 months after the index visits and total and spine-specific relative value units (RVUs from electronic health records were tabulated over 1 year. We calculated correlation coefficients between RVUs and 12- and 24-month PROs and conducted linear regressions with each 12- and 24-month PRO as the outcome variables and RVUs as predictors of interest. Results: We observed very weak correlations between worse PROs at 12 and 24 months and greater 12-month utilization. In regression analyses, we observed slight associations between greater utilization and worse 12- and 24-month PROs. Discussion: We found that 12-month health care utilization is not strongly associated with PROs at 12 or 24 months.

    2017-01-01

    This study evaluated the associations between job strain and arginase I in 378 healthy Japanese factory workers by a cross-sectional study measuring nitric oxide (NO)-related parameters (arginase I, L-arginine, exhaled nitric oxide (FeNO), and NOx), clinical parameters, and job strain using a Japanese version of the Job Content Questionnaire by Karasek. Arginase I and FEV1% were negatively correlated with job strain and positively correlated with job control and social support. FeNO and hs-CRP were negatively correlated with job strain. Multiple regression analysis showed negative association of arginase I with job strain and positive association with job control and social support in females. It is concluded that serum levels of arginase I may be useful biomarkers for the diagnosis of job stress in healthy female workers, although many factors can be influencing the data. PMID:28403218

    To investigate the association between lifestyle-related health behaviors including sleep and the cluster of physical activity, no tobacco use, fruits and vegetables intake, and alcohol consumption termed the "Optimal Lifestyle Metric" (OLM), and employee productivity. Data were obtained from employee health assessments (N = 18,079). Regression techniques were used to study the association between OLM and employee productivity, sleep and employee productivity, and the interaction of both OLM and sleep on employee productivity. Employees who slept less or more than 7 or 8 hours per night experienced significantly more productivity loss. Employees who adhered to all four OLM behaviors simultaneously experienced less productivity loss compared with those who did not. Adequate sleep and adherence to the OLM cluster of behaviors are associated with significantly less productivity loss.

    This study aimed to determine the characteristics of tinnitus and tinnitus-related variables and explore their possible relationship with tinnitus-related handicap. Eighty-one patients with chronic tinnitus were included. The study protocol measured hearing status, tinnitus pitch, loudness, maskability and loudness discomfort levels. All patients filled in the Tinnitus Sample Case History Questionnaire, the Hyperacusis Questionnaire and the Tinnitus Handicap Inventory. The relationship of each variable with the Tinnitus Handicap Inventory score was evaluated by univariate and multivariate analyses. Five univariables were associated with the Tinnitus Handicap Inventory score: loudness discomfort level, subjective tinnitus loudness, tinnitus awareness, noise intolerance and Hyperacusis Questionnaire score. Multiple regression analysis showed that the Hyperacusis Questionnaire score and tinnitus awareness were independently associated with the Tinnitus Handicap Inventory score. Hyperacusis and tinnitus awareness were independently associated with the Tinnitus Handicap Inventory score. Questionnaires on tinnitus and hyperacusis are especially suited to providing additional insight into tinnitus-related handicap and are therefore useful for evaluating tinnitus patients.

    To investigate the association between traumatic brain injury (TBI)-related brain lesions and long-term caregiver burden in relation to dysexecutive syndrome. National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Maryland. A total of 256 participants: 105 combat veterans with TBI, 23 healthy control combat veterans (HCv), and 128 caregivers. Caregiver burden assessed by the Zarit Burden Interview at 40 years postinjury. Participants with penetrating TBI were compared with HCv on perceived caregiver burden and neuropsychological assessment measures. Data of computed tomographic scans (overlay lesion maps of participants with a penetrating TBI whose caregivers have a significantly high burden) and behavioral statistical analyses were combined to identify brain lesions associated with caregiver burden. Burden was greater in caregivers of veterans with TBI than in caregivers of HCv. Caregivers of participants with lesions affecting cognitive and behavioral indicators of dysexecutive syndrome (ie, left dorsolateral prefrontal cortex and dorsal anterior cingulate cortex) showed greater long-term burden than caregivers of participants with lesions elsewhere in the brain. The TBI-related brain lesions have a lasting effect on long-term caregiver burden due to cognitive and behavioral factors associated with dysexecutive syndrome.

    A cross-sectional study was conducted to explore what work-related factors were associated with job stress among pediatricians in Japan, as determined by the demand-control-support model and psychosomatic symptoms. We sent an anonymous questionnaire to a random sample of 3,000 members selected from the nationwide register of the Japan Pediatric Society and received 850 responses (response rate, 28%). Data from the 590 respondents who worked more than 35 h per week as a pediatrician and had no missing responses in the questionnaire were analyzed. We measured workload-related variables (e.g. working hours, work schedule) and recovery-related variables (e.g. workdays with no overtime, days off with no work in the past month) as exposure variables, and psychosocial job stressors (the Brief Job Stress Questionnaire) and psychosomatic symptoms as outcome variables. Longer working hours per week was significantly associated with greater job demand, lower job control and more psychosomatic symptoms (pworking hours, more workdays with no overtime was significantly associated with lower job demand, greater job control and fewer psychosomatic symptoms (pworking hours is a risk factor for job stressors and psychosomatic symptoms, and that workdays with no overtime is a protective factor which may facilitate recovery. Controlling working hours and encouraging non-overtime workdays may be important for reducing job stressors and psychosomatic symptoms among pediatricians in Japan.

    Creativity generally involves the conception of original and valuable ideas. Previous studies have suggested an association between creativity and the dopaminergic system, and that physical activity facilitates creativity. Iron plays a key role in the dopaminergic system and physical activity. Here, we newly investigated the associations between hair iron levels and creativity, dopamine-related traits and states [novelty seeking, extraversion, and vigor (motivational state)], as well as the physical activity level. In the present study, we addressed this issue by performing a hair mineral analysis to determine iron levels and a behavioral creativity test of divergent thinking and related psychological measures among young adults (254 men, 88 women; mean age 20.79 ± 2.03 years). Iron levels did not show any significant association with creativity but displayed significant positive associations with novelty seeking, extraversion, and physical activity level. These results may be partly congruent with the notion that iron plays a key role in the dopaminergic system and imply that iron is important for traits and physical activity, which facilitate creativity. Future interventional or longitudinal studies are warranted to identify any causal effects. PMID:24385960

    To investigate the association between work-related psychosocial factors and the prevalence of mental disorders among pre-school and elementary school teachers. This cross-sectional study was undertaken with 1,024 teachers from municipal public schools and from the ten largest private schools in Vitória da Conquista, Bahia State (Northeastern Brazil) in 2001. The main independent variable was based on the demand-control model, which classifies individuals according to their job pressures. The dependent variable was the incidence of mental disorders as evaluated by a self-reporting questionnaire. The measure of frequency was prevalence, and the measure of association was the prevalence ratio. A logistic regression model was used as the main statistical technique. There was a 44% prevalence of mental disorders among teachers. Evidence suggests that these were associated with work-related demands and control issues, after controlling for confounding variables such as sex, geographic region and social support. The prevalence of mental disorders among high-strain teachers was 1.5 times greater than that among low-strain teachers. The prevalence of mental disorders was high among teachers of the municipality. There was evidence that this was associated with job demands.

    Verify the prevalence and sociodemographic and economic factors associated with behavior change stages for habitual physical activity practice in adolescents from Santa Catarina. Secondary analysis of a study on the Behavior of Adolescents from Santa Catarina (CompAC 2). Cross-sectional school-based study of 6,529 high-school students (males, n=2,903) from the state of Santa Catarina public education system in 2011, aged 15 to 19 years. Multinomial logistic regression (crude and adjusted) was used to measure the association. The highest and lowest prevalence rates were found in the maintenance (43.9%) and precontemplation stages (7.0%), respectively. The stages of action, preparation and contemplation showed similar results: 16.2%; 17.0% and 15.6%; respectively. Male adolescents show higher prevalence in the maintenance stage in relation to females and these show a higher prevalence in preparation, contemplation and precontemplation. All the assessed variables (gender, age, area of residence, employment status, family income, maternal education and school grade), with the exception of school shift, were associated with at least one of the stages. A large proportion of adolescents are in the pre-adoption stages and most of these have the intention to start regular physical activity. With the exception of school shift, the assessed variables were associated with stages in different ways, showing different profiles in relation to sociodemographic and economic characteristics in each subgroup.

    The aim of the present study was to evaluate the association between statin use and the risk of age-related macular degeneration (AMD). A systematic search of the PubMed, EMBASE and ISI web of science databases was used to identify eligible published literatures without language restrictions up to April 2015. Summary relative ratios (RRs) and 95% CIs were estimated using a fixed-effect or random-effects model. A total of 14 studies met the inclusion criteria and were included in this meta-analysis. No significant association was observed between statin use and the risk of any AMD (RR, 0.95; 95% CI, 0.74–1.15); and stratified analysis showed that statins had a significantly different effects on early and late stages of AMD. For early AMD, statin use significantly reduced the risk approximately 17% (RR, 0.83; 95% CI, 0.66–0.99). At the late stage, we observed a significant protective association of statin use with exudative AMD (RR, 0.90; 95% CI, 0.80–0.99), in contrast with the absent association between statins and geographic atrophy (RR, 1.16; 95% CI, 0.77–1.56). These results demonstrated that statin use was protective for early and exudative AMD. Additional large prospective cohort studies and RCTs are required to determine the potential effect of statins on AMD prevention. PMID:26658620

    It has been suggested that polymorphisms in the monoamine oxidase A (MAO-A) gene are associated with aggressive and impulsive behaviors. In the present study, we investigated the association of the MAO-A variable number of tandem repeat polymorphism in the promoter region (MAO-A uVNTR) with anger-related personality traits. Specifically, MAO-A uVNTR polymorphisms were examined for associations with the State-Trait Anger Expression Inventory (STAXI) scores in 211 normal Korean women. All subjects were assessed using the STAXI and genotyped for MAO-A uVNTR status. The scores on the STAXI subscales differed significantly among the MAO-A uVNTR polymorphism genotypes in terms of anger expression-out (AX-Out) scores. Post hoc comparisons revealed significant differences between the 3/3 and 4/4, and between 3/4 and 4/4 polymorphisms. However, no significant difference was observed in other STAXI subscale scores among these genotypes. Subjects with the high-activity MAO-A uVNTR had significantly higher AX-Out scores than subjects with other genotypes. MAO-A uVNTR polymorphisms may contribute in part to the expression of anger. These findings support the hypothesis that this polymorphism in the MAO-A gene may be associated with anger-related personality traits in Korean women. (c) 2007 S. Karger AG, Basel.

    Full Text Available Creativity generally involves the conception of original and valuable ideas. Previous studies have suggested an association between creativity and the dopaminergic system, and that physical activity facilitates creativity. Iron plays a key role in the dopaminergic system and physical activity. Here, we newly investigated the associations between hair iron levels and creativity, dopamine-related traits and states [novelty seeking, extraversion, and vigor (motivational state], as well as the physical activity level. In the present study, we addressed this issue by performing a hair mineral analysis to determine iron levels and a behavioral creativity test of divergent thinking and related psychological measures among young adults (254 men, 88 women; mean age 20.79 ± 2.03 years. Iron levels did not show any significant association with creativity but displayed significant positive associations with novelty seeking, extraversion, and physical activity level. These results may be partly congruent with the notion that iron plays a key role in the dopaminergic system and imply that iron is important for traits and physical activity, which facilitate creativity. Future interventional or longitudinal studies are warranted to identify any causal effects.

    2017-03-01

    Neurofibromatosis type I (NF1) is a relatively common disorder associated with a range of neurologic sequelae. Refractory epilepsy occurs in 4-13% of NF1 patients. Hippocampal sclerosis and focal cortical dysplasia, both well-defined epilepsy-related entities, have been described in a subset of cases. To our knowledge, there has been only one other series describing coexistent focal cortical dysplasia and hippocampal sclerosis in the setting of NF1. We report two such patients who presented with intractable seizures requiring epilepsy surgery. Histologically, the hippocampal sclerosis specimen met criteria for the International League Against Epilepsy (ILAE) hippocampal sclerosis subtypes Ia and II respectively. The associated focal cortical dysplasia observed within the resected temporal lobe were both consistent with ILAE focal cortical dysplasia type IIIa (e.g. associated with a secondary lesion). Post-operatively, both patients had recurrence of habitual seizures, with one case continuing to have intractable seizures following two subsequent temporal lobectomies. Although hippocampal sclerosis association with focal cortical dysplasia is well document in epilepsy, it has been rarely described in the setting of neurofibromatosis type I. Although prior surgical series have shown good epilepsy surgery outcomes within neurofibromatosis type I, these two cases did not. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Rationale: Statins, or HMG-CoA reductase inhibitors, may aid in the treatment of asthma through their pleiotropic antiinflammatory effects. Objectives: To examine the effect of statin therapy on asthma-related exacerbations using a large population-based cohort. Methods: Statin users aged 31 years or greater with asthma were identified from the Population-Based Effectiveness in Asthma and Lung population, which includes data from five health plans. Statin exposure and asthma exacerbations were assessed over a 24-month observation period. Statin users with a statin medication possession ratio greater than or equal to 80% were matched to non–statin users by age, baseline asthma therapy, site of enrollment, season at baseline, and propensity score, which was calculated based on patient demographics and Deyo-Charlson conditions. Asthma exacerbations were defined as two or more oral corticosteroid dispensings, asthma-related emergency department visits, or asthma-related hospitalizations. The association between statin exposure and each of the three outcome measures was assessed using conditional logistic regression. Measurements and Main Results: Of the 14,566 statin users, 8,349 statin users were matched to a nonuser. After adjusting for Deyo-Charlson conditions that remained unbalanced after matching, among statin users, statin exposure was associated with decreased odds of having asthma-related emergency department visits (odds ratio [OR], 0.64; 95% confidence interval [CI], 0.53–0.77; P statin users with asthma, statin exposure was associated with decreased odds of asthma-related emergency department visits and oral corticosteroid dispensings.

    To assess associations between adiposity and hippocampal-dependent and hippocampal-independent memory forms among prepubertal children. Prepubertal children (age 7-9 years; n = 126), classified as non-overweight (memory tasks. Performance was assessed with both direct (behavioral accuracy) and indirect (preferential disproportionate viewing [PDV]) measures. Adiposity (ie, percent whole-body fat mass, subcutaneous abdominal adipose tissue, visceral adipose tissue, and total abdominal adipose tissue) was assessed by dual-energy X-ray absorptiometry. Backward regression identified significant (P memory performance. Covariates included age, sex, pubertal timing, socioeconomic status (SES), IQ, oxygen consumption, and BMI z-score. Among overweight/obese children, total abdominal adipose tissue was a significant negative predictor of relational memory behavioral accuracy, and pubertal timing together with SES jointly predicted the PDV measure of relational memory. In contrast, among non-overweight children, male sex predicted item memory behavioral accuracy, and a model consisting of SES and BMI z-score jointly predicted the PDV measure of relational memory. Regional, but not whole-body, fat deposition was selectively and negatively associated with hippocampal-dependent relational memory among overweight/obese prepubertal children.

    The development of representations for taxonomic categories is influenced by many factors, such as age, life experiences, and education. It was hypothesized that Mosuos might be aware of taxonomic relations differently than Hans, as indicated by Sha (1996). Three experiments--word associations, lexicon decisions, and semantic categorizations--were conducted on young adults of Mosuos and Hans and consistent results were obtained: the Mosuos were found both similar to and different from the Hans in their experimental performance. They were apparently aware of taxonomic relations less than the Hans among categories of different levels and among categories of basic level, consistent with the conclusion that the uniqueness of a specific culture influences the people's representations for the hierarchically structured taxonomic categories (López, Atran, Coley, Medin & Smith, 1997). The present forms of education did not seem to be as effective as educators expected to help promote Mosuo children's development of knowledge of taxonomic categories. If school education would be available that is compatible with the cultural value of a relatively isolated, small population, such as Mosuos, and is of practical value for the young children to develop a better knowledge of the world, then a study would be of critical value into how educated individuals would be different from uneducated ones in their awareness of taxonomic relations. © 2012 The Authors.

    Relative terms often appear together in the literature. Methods have been presented for weighting relativity of pairwise terms by their co-occurring literature and inferring new relationship. Terms in the literature are also in the directed acyclic graph of ontologies, such as Gene Ontology and Disease Ontology. Therefore, semantic association between terms may help for establishing relativities between terms in literature. However, current methods do not use these associations. In this paper, an adjusted R-scaled score (ARSS) based on information content (ARSSIC) method is introduced to infer new relationship between terms. First, set inclusion relationship between terms of ontology was exploited to extend relationships between these terms and literature. Next, the ARSS method was presented to measure relativity between terms across ontologies according to these extensional relationships. Then, the ARSSIC method using ratios of information shared of term's ancestors was designed to infer new relationship between terms across ontologies. The result of the experiment shows that ARSS identified more pairs of statistically significant terms based on corresponding gene sets than other methods. And the high average area under the receiver operating characteristic curve (0.9293) shows that ARSSIC achieved a high true positive rate and a low false positive rate.

    To examine the relations between traditionally assessed early maladaptive schemas and the attachment-specific secure base script (a script-like representation of what individuals expect to happen when they face distress), to inform our understanding of beliefs about the self in relation to others. The present study took an ecologically driven approach, assessing knowledge of the secure base script from descriptions of current relationships. A cross-sectional design was used. One hundred forty-six undergraduate students, recruited as part of a larger study on adversity and self-concept, provided narrative descriptions of their current relationships. Narratives were coded for attachment-related 'secure base' content using a secure base script scale for relationship narratives. Early maladaptive schemas were assessed with the Young Schema Questionnaire, and attachment was additionally evaluated using the Experiences in Close Relationships questionnaire. Self-reported attachment avoidance and anxiety were related to secure base script content in theory-consistent ways. The extent to which participants described secure base script content was inversely associated with four out of five maladaptive schemas characterized most centrally by disconnection from others. Furthermore, these associations remained significant when controlling for self-reported attachment style. Self-reported attachment avoidance and anxiety also were related to maladaptive schemas in a predictable pattern. Results bridge cognitive and attachment theories, supporting the interrelatedness of secure base script knowledge assessed in current relationships, and schema-related content regarding connectedness with others. Better integration of theories regarding internal representations may serve to enrich psychotherapeutic formulation from a variety of clinical perspectives.

    Approximately 3.2 million people die of non-communicable diseases (NCD) each year due to insufficient physical activity. Physical activity guidelines are possibly perceived as too demanding and might thus pose a barrier. We addressed the question if a more stable physical activity pattern is associated with higher levels of health-related fitness than one with high and low intensities, regardless of the physical activity level (PAL). Physical activity was objectively measured in 296 men and women (53.7 ± 8.94 years) with the SenseWear Pro Armband(®). Using this data, the PAL and a Gini index were calculated to report the physical activity pattern. Health-related fitness was expressed as a fitness index. PAL was weakly correlated to health-related fitness (r = 0.38, P physical activity pattern or variability in intensities throughout the day.

    Full Text Available Background: Phthalate exposure may increase the risk of asthma. Little is known about whether oxidative-stress related genes may alter this association. First, this motivated us to investigate whether genetic polymorphisms of the oxidative-stress related genes glutathione S-transferase Mu 1 (GSTM1, glutathione S-transferase pi 1 (GSTP1, superoxide dismutase 2 (SOD2, catalase (CAT, myeloperoxidase (MPO, and EPHX1 in children are associated with phthalate urine concentrations. Second, we addressed the question whether these genes may affect the influence of phthalates on asthma. Methods: In a case-control study composed of 126 asthmatic children and 327 controls, urine phthalate metabolites (monoethyl phthalate (MEP, monobutyl phthalate (MBP, monobenzyl phthalate (MBzP, and mono(2-ethyl-5-hydroxyhexylphthalate (MEHHP were measured by UPLC-MS/MS at age 3. Genetic variants were analyzed by TaqMan assay. Information on asthma and environmental exposures was also collected. Analyses of variance and logistic regressions were performed. Results: Urine MEHHP levels were associated with asthma (adjusted OR 1.33, 95% CI (1.11–1.60. Children with the GSTP1 (rs1695 AA and SOD2 (rs5746136 TT genotypes had higher MEHHP levels as compared to GG and CC types, respectively. Since only SOD2 TT genotype was significantly associated with asthma (adjusted OR (95% CI: 2.78 (1.54–5.02, we estimated whether SOD2 variants modify the association of MEHHP levels and asthma. As MEHHP concentrations were dependent on GSTP1 and SOD2, but the assessment of interaction requires independent variables, we estimated MEHHP residuals and assessed their interaction, showing that the OR for SOD2 TT was further elevated to 3.32 (1.75–6.32 when the residuals of MEHHP were high. Conclusions: Urine phthalate metabolite concentrations are associated with oxidative-stress related genetic variants. Genetic variants of SOD2, considered to be reflect oxidative stress metabolisms, might

    Full Text Available Obesity is a well-known risk factor for type 2 diabetes. Genome-wide association studies have identified a number of genetic loci associated with obesity. The aim of this study is to examine the contribution of obesity-related genomic loci to type 2 diabetes in a Chinese population.We successfully genotyped 18 obesity-related single nucleotide polymorphisms among 5338 type 2 diabetic patients and 4663 controls. Both individual and joint effects of these single nucleotide polymorphisms on type 2 diabetes and quantitative glycemic traits (assessing β-cell function and insulin resistance were analyzed using logistic and linear regression models, respectively.Two single nucleotide polymorphisms near MC4R and GNPDA2 genes were significantly associated with type 2 diabetes before adjusting for body mass index and waist circumference (OR (95% CI = 1.14 (1.06, 1.22 for the A allele of rs12970134, P = 4.75×10(-4; OR (95% CI = 1.10 (1.03, 1.17 for the G allele of rs10938397, P = 4.54×10(-3. When body mass index and waist circumference were further adjusted, the association of MC4R with type 2 diabetes remained significant (P = 1.81×10(-2 and that of GNPDA2 was attenuated (P = 1.26×10(-1, suggesting the effect of the locus including GNPDA2 on type 2 diabetes may be mediated through obesity. Single nucleotide polymorphism rs2260000 within BAT2 was significantly associated with type 2 diabetes after adjusting for body mass index and waist circumference (P = 1.04×10(-2. In addition, four single nucleotide polymorphisms (near or within SEC16B, BDNF, MAF and PRL genes showed significant associations with quantitative glycemic traits in controls even after adjusting for body mass index and waist circumference (all P values<0.05.This study indicates that obesity-related genomic loci were associated with type 2 diabetes and glycemic traits in the Han Chinese population.

    Middle childhood is an important period for individual trait shaping, during which children are likely to generate and own their distinct neuromechanism of creative-related traits. This study used voxel-based morphometry (VBM) to identify the brain structures that underlie trait creativity (as measured by the Williams Creativity Aptitude Test) in a sample of typical developing children (aged 9-12, n=64). The results indicated that several emotion-related regions may relate to trait creativity in middle children. Specifically, the regional gray matter volume (rGMV) in the amygdala and hippocampus was negatively related to creative traits of challenge and risk-taking, which indicates that children with increased trait creativity may be more impulsive when they engage in creative activities. An increased rGMV in the orbitofrontal cortex (OFC) was related to an increased trait of imagination, which may be associated with stronger sensation-seeking in children. These findings are the first to demonstrate the brain structures that underlie trait creativity in middle children, and indicated that, driven by a relatively stronger effect of sensation-seeking (via recruitment of the OFC), children with increased trait creativity may exhibit more risk-taking and challenging behaviors (via recruitment of the amygdala and hippocampus) when they practice their creativity.

    The effect of handedness on cognitive functioning has been the subject of much controversy. The influential "pathological left-handedness theory" posited by Coren and Halpern (1991) claims that left-handedness is probabilistically related to deviations from the neurological and cognitive norm. Many studies have failed to find negative effects of left-handedness on cognitive functioning, but most of these studies related handedness to cognition at one moment in time. Such studies do not exclude the possibility that sinistrality may be related to a more pronounced age-related longitudinal decline in cognitive functions. This hypothesis was tested in the present study. In a longitudinal study involving a large population sample of cognitively intact people aged at least 50 years at baseline, we evaluated the effect of handedness on age-related decline in four major cognitive domains: speed of information processing, verbal learning, long-term verbal memory, and executive functioning. The results failed to provide support for the hypothesis that sinistrality is associated with a more pronounced age-related cognitive decline. Recommendations for future studies are provided.

    Background Eye injuries are a prevalent workplace injury and cause substantial disability when vision is impaired. Objective To examine work-relatedness of demographic, injury, and clinical characteristics of eye injuries in a large clinic in Bosnia and Herzegovina. Methods We performed a nine-year retrospective study of patients admitted with an eye injury to the Canton Hospital in Zenica, Bosnia and Herzeogvina. Controlling for age and sex, we used logistic regression to examine the influence of work-relatedness on patient and injury characteristics and clinical outcomes. Results Of 258 patients, 71 (27.5%) had work-related and 180 (69.8%) had non-work-related eye injuries. Work-related eye injury was associated with age, education, occupation, and injury type. Agricultural workers were eight times more likely to experience work-related eye injury (95%CI = 1.21–152.0) compared to manual workers. Work-relatedness of injury did not predict final visual acuity or length of hospital stay. Conclusion Promotion of eye safety is needed countrywide. Occupational eye protection is a priority due to the relatively proportion of eye injuries and the workplace being a relatively controlled environment. PMID:27813453

    Epilepsy is the third-leading cause of psychiatry disability in China, and intellectual disability (ID) is also 1 major type of disabilities in China. This study estimates the prevalence of comorbidities with ID and epilepsy-related psychiatry disability (EPD) and examines mutual associations within ID and EPD.Data were taken from the Second China National Sample Survey on Disability, which was a nationally representative, population-based survey. To derive a nationally representative sample, the survey used multistage, stratified, cluster random sampling with probability proportional to size. The disabled people who had ID and EPD based on the World Health Organization International Classification of Functioning, Disability, and Health and the International Statistical Classification of Diseases. The cox-proportional hazards model was used to examine the associations between ID and EPD considering the happened sequence of ID and EPD.The prevalence of ID with EPD was 0.14 (95% confidence interval: 0.09-0.19) per 1000 people. Age was strongly associated with the risk of EPD, which was diagnosed after ID, especially among young ID population. Except for age, other variables were also associated between ID and EPD considering sequence of ID and EPD.This study is the first national study to explore mutual associations with ID and EPD and highlights the young ID children with high risk of development of epilepsy. To address the challenge of ID with EPD disability in China, the government should adjust its strategies for healthcare systems to prevent disability.

    Age-related macular degeneration (AMD), a multifactorial, neurodegenerative disease, is a leading cause of vision loss. With the rapid advancement of DNA sequencing technologies, many AMD-associated genetic polymorphisms have been identified. Currently, the most time consuming steps of these studies are patient recruitment and phenotyping. In this study, we describe the development of an automated algorithm to identify neovascular (wet) AMD, non-neovascular (dry) AMD and control subjects using electronic medical record (EMR)-based criteria. Positive predictive value (91.7%) and negative predictive value (97.5%) were calculated using expert chart review as the gold standard to assess algorithm performance. We applied the algorithm to an EMR-linked DNA bio-repository to study previously identified AMD-associated single nucleotide polymorphisms (SNPs), using case/control status determined by the algorithm. Risk alleles of three SNPs, rs1061170 (CFH), rs1410996 (CFH), and rs10490924 (ARMS2) were found to be significantly associated with the AMD case/control status as defined by the algorithm. With the rapid growth of EMR-linked DNA biorepositories, patient selection algorithms can greatly increase the efficiency of genetic association study. We have found that stepwise validation of such an algorithm can result in reliable cohort selection and, when coupled within an EMR-linked DNA biorepository, replicates previously published AMD-associated SNPs.

    To investigate the association between hormone receptors and HER-2/neu in different age groups of women with breast cancers. A total of 1036 women with breast cancers were recruited. All the patients were divided into nine groups. The expression of hormone receptors and HER-2/neu was studied by IHC, while FISH test was used to determine HER-2/neu status in cases scored IHC 2+. The association between hormone receptors and HER-2/neu in different age groups was evaluated using the χ(2) test. Multivariate analysis was used to find out the independent factors predicting HER-2/neu amplification. Significant findings: The expression of ER and PR was inversely correlated with HER-2/neu status in women aged >40 years. By multivariate analysis, as far as the overall groups were concerned, PR, lymph node status and tumor grade were independently associated with HER-2/neu; Considering the younger age group (≤ 40), the only predictor for HER-2/neu was the tumor grade; Considering the older age group (>40), tumor grade, PR status, tumor size and lymph node status were associated with HER-2/neu overexpression. Our data suggest that the association between ER, PR and HER-2/neu is age-related. The negative relationship is only applied for women aged >40 years.

    Newspapers are an important source of information. The discourses within the media can influence public attitudes and support or discourage stereotypical portrayals of older individuals. This study critically examined discourses within a Canadian newspaper in terms of stereotypical depictions of age-related health conditions and assistive technology devices (ATDs). Four years (2009-2013) of Globe and Mail articles were searched for terms relevant to the research question. A total of 65 articles were retained, and a critical discourse analysis (CDA) of the texts was conducted. The articles were coded for stereotypes associated with age-related health conditions and ATDs, consequences of the stereotyping, and context (overall setting or background) of the discourse. The primary code list included 4 contexts, 13 stereotypes, and 9 consequences of stereotyping. CDA revealed discourses relating to (a) maintaining autonomy in a stereotypical world, (b) ATDs as obstacles in employment, (c) barriers to help seeking for age-related conditions, and (d) people in power setting the stage for discrimination. Our findings indicate that discourses in the Canadian media include stereotypes associated with age-related health conditions. Further, depictions of health conditions and ATDs may exacerbate existing stereotypes about older individuals, limit the options available to them, lead to a reduction in help seeking, and lower ATD use. Education about the realities of age-related health changes and ATDs is needed in order to diminish stereotypes and encourage ATD uptake and use. © The Author 2015.

    Obesity has been characterized by alterations in brain structure and function associated with emotion processing and regulation. Particularly, aberrations in food-related reward processing have been frequently demonstrated in obese subjects. However, it remains unclear whether reward-associated functional aberrations in obesity are specific for food-related stimuli or represent a general deficit in reward processing, extending to other stimulus domains. Given the crucial role of rewarding effects in the development of obesity and the ongoing discussion on overlapping neurobiological traits of obesity and psychiatric disorders such as depression and substance-related disorders, this study aimed to investigate the possibility of altered reward processing in obese subjects to occur in the absence of food-related stimuli during a monetary reward condition. Twenty-nine healthy obese subjects (body mass index >30) and 29 healthy, age-, and sex-matched control subjects of normal weight underwent functional MRI during a frequently used card guessing paradigm. A Group × Condition (win vs. loss) ANOVA was conducted to investigate differences between obese and normal-weight subjects. We found significant Group × Condition interaction effects in brain areas involved in emotion regulation and reward processing including the insula, the striatum, and the orbitofrontal cortex (OFC). This interaction was predominantly driven by a significant increase in blood oxygenation level dependent (BOLD) response in obese individuals while experiencing reward. Enhanced neural activation in obesity during reward processing seems to be apparent even in the absence of food-related stimuli and, thus, might point to generalized dysfunctions in reward-related brain circuits in obese individuals. © 2015 Wiley Periodicals, Inc.

    Late-life depression encompasses both patients with late-life onset of depression (>60 years) and older adults with a prior and current history of depression. The aim of the study was to analyze the impact of the economic condition and family relations in childhood as risk factors for late-life depression. This was an analytical cross-sectional study comprising 120 subjects, 60 patients with unipolar depression and 60 subjects without depressive disorders, diagnosed in accordance with the 10-th International Classification of Mental and Behavioural Disorders. All participants in the study were above the age of 60 and there was no significant statistical difference in the sex proportion in both groups (p>0.05). Data for the examination were taken from a self-reported questionnaire designed for our aim. The Geriatric Depression Scale was used to measure depressive symptoms. Our results have shown that severe financial difficulties are important events in childhood and are risk factors for depression in the elderly (Chi-square=12.68, df=2, p=0.0018). Our investigation has found the association of family relations with late-life depression. In fact, conflictual relations in the family were more common in the experimental group than in the control group (Chi-square=14.32, df=3, p=0.0025). Furthermore, father's addiction to alcohol in childhood was associated with depression in later life (p=0.013). The difference in childhood emotional neglect and unequal treatment between siblings in both groups was insufficient to be confirmed statistically, but the examinees with this trauma had a threefold higher chance of having depression later in life (Odds ratio=3.04, 95% CL0.92 family conflicts during childhood are associated with late-life depression. Father's addiction to alcohol and parents' negative personal character traits are associated with depression in the elderly.

    Full Text Available BACKGROUND: Feasibility of genotyping of hundreds and thousands of single nucleotide polymorphisms (SNPs in thousands of study subjects have triggered the need for fast, powerful, and reliable methods for genome-wide association analysis.

We also show that the power of our proposed GRAMMAR-GC approaches to that of the 'gold standard' MG for all models and pedigrees studied. We show that this method is both feasible and powerful and has correct type 1 error in the context of genome-wide association analysis

    OBJECTIVE In the general, nondiabetic population, fasting glucose increases only slightly over time, whereas 2-h postload glucose shows a much steeper age-related rise. The reasons underlying these different age trajectories are unknown. We investigated whether common genetic variants associated with fasting and 2-h glucose contribute to age-related changes of these traits. RESEARCH DESIGN AND METHODS We studied 5,196 nondiabetic participants of the Whitehall II cohort (aged 40–78 years) attending up to four 5-yearly oral glucose tolerance tests. A genetic score was calculated separately for fasting and 2-h glucose, including 16 and 5 single nucleotide polymorphisms, respectively. Longitudinal modeling with age centered at 55 years was used to study the effects of each genotype and genetic score on fasting and 2-h glucose and their interactions with age, adjusting for sex and time-varying BMI. RESULTS The fasting glucose genetic score was significantly associated with fasting glucose with a 0.029 mmol/L (95% CI 0.023–0.034) difference (P = 2.76 × 10−21) per genetic score point, an association that remained constant over time (age interaction P = 0.17). Two-hour glucose levels differed by 0.076 mmol/L (0.047–0.105) per genetic score point (P = 3.1 × 10−7); notably, this effect became stronger with increasing age by 0.006 mmol/L (0.003–0.009) per genetic score point per year (age interaction P = 3.0 × 10−5), resulting in diverging age trajectories by genetic score. CONCLUSIONS Common genetic variants contribute to the age-related rise of 2-h glucose levels, whereas associations of variants for fasting glucose are constant over time, in line with stable age trajectories of fasting glucose.

    Full Text Available Residual feed intake (RFI, a measure of feed efficiency, is the difference between observed feed intake and the expected feed requirement predicted from growth and maintenance. Pigs with low RFI have reduced feed costs without compromising their growth. Identification of genes or genetic markers associated with RFI will be useful for marker-assisted selection at an early age of animals with improved feed efficiency.Whole genome association studies (WGAS for RFI, average daily feed intake (ADFI, average daily gain (ADG, back fat (BF and loin muscle area (LMA were performed on 1,400 pigs from the divergently selected ISU-RFI lines, using the Illumina PorcineSNP60 BeadChip. Various statistical methods were applied to find SNPs and genomic regions associated with the traits, including a Bayesian approach using GenSel software, and frequentist approaches such as allele frequency differences between lines, single SNP and haplotype analyses using PLINK software. Single SNP and haplotype analyses showed no significant associations (except for LMA after genomic control and FDR. Bayesian analyses found at least 2 associations for each trait at a false positive probability of 0.5. At generation 8, the RFI selection lines mainly differed in allele frequencies for SNPs near (<0.05 Mb genes that regulate insulin release and leptin functions. The Bayesian approach identified associations of genomic regions containing insulin release genes (e.g., GLP1R, CDKAL, SGMS1 with RFI and ADFI, of regions with energy homeostasis (e.g., MC4R, PGM1, GPR81 and muscle growth related genes (e.g., TGFB1 with ADG, and of fat metabolism genes (e.g., ACOXL, AEBP1 with BF. Specifically, a very highly significantly associated QTL for LMA on SSC7 with skeletal myogenesis genes (e.g., KLHL31 was identified for subsequent fine mapping.Important genomic regions associated with RFI related traits were identified for future validation studies prior to their incorporation in marker

    Full Text Available The emerging field of sociogenomics explores the relations between social behavior and genome structure and function. An important question is the extent to which associations between social behavior and gene expression are conserved among the Metazoa. Prior experimental work in an invertebrate model of social behavior, the honey bee, revealed distinct brain gene expression patterns in African and European honey bees, and within European honey bees with different behavioral phenotypes. The present work is a computational study of these previous findings in which we analyze, by orthology determination, the extent to which genes that are socially regulated in honey bees are conserved across the Metazoa. We found that the differentially expressed gene sets associated with alarm pheromone response, the difference between old and young bees, and the colony influence on soldier bees, are enriched in widely conserved genes, indicating that these differences have genomic bases shared with many other metazoans. By contrast, the sets of differentially expressed genes associated with the differences between African and European forager and guard bees are depleted in widely conserved genes, indicating that the genomic basis for this social behavior is relatively specific to honey bees. For the alarm pheromone response gene set, we found a particularly high degree of conservation with mammals, even though the alarm pheromone itself is bee-specific. Gene Ontology identification of human orthologs to the strongly conserved honey bee genes associated with the alarm pheromone response shows overrepresentation of protein metabolism, regulation of protein complex formation, and protein folding, perhaps associated with remodeling of critical neural circuits in response to alarm pheromone. We hypothesize that such remodeling may be an adaptation of social animals to process and respond appropriately to the complex patterns of conspecific communication essential for

    Management of patients with glioblastoma (GBM) often includes radiation (RT) and temozolomide (TMZ). The association between severe treatment-related lymphopenia (TRL) after the standard chemoradiation and reduced survival has been reported in GBM patients with the median age of 57. Similar findings were described in patients with head and neck, non-small cell lung, and pancreatic cancers. This retrospective study is designed to evaluate whether elderly GBM patients (age ≥65) develop similar TRL after RT/TMZ and whether such TRL is associated with decreased survival. Serial total lymphocyte counts (TLC) were retrospectively reviewed in patients (age ≥65) with newly diagnosed GBM undergoing RT/TMZ and associated with treatment outcomes. Seventy-two patients were eligible: median KPS 70, median age 71 years (range 65-86) with 56 % of patients >70 years, 53% female, 31% received RT ≤45 Gy. Baseline median TLC was 1100 cells/mm(3) which fell by 41% to 650 cells/mm(3) 2 months after initiating RT/TMZ (p < 0.0001). Patients with TLC <500 cells/mm(3) at 2 months had a shorter survival than those with higher TLCs with a median overall survival of 4.6 versus 11.6 months, respectively. Multivariate analysis revealed a significant association between TRL and survival (HR 2.76, 95% CI 1.30-5.86, p = 0.008). Treatment-related lymphopenia is frequent, severe, and an independent predictor for survival in elderly patients with GBM. These findings add to the body of evidence that immunosuppression induced by chemoradiation is associated with inferior clinical outcomes. Prospective studies are needed to confirm these findings suggesting that immune preservation is important in this cancer.

    Full Text Available BackgroundVisceral adiposity is related to insulin resistance. Skeletal muscle plays a central role in insulin-mediated glucose disposal; however, little is known about the association between muscle mass and metabolic syndrome (MS. This study is to clarify the clinical role of skeletal muscle mass in development of MS.MethodsA total of 1,042 subjects were enrolled. Subjects with prior MS and chronic diseases were excluded. After 24 months, development of MS was assessed using NCEP-ATP III criteria. Skeletal muscle mass (SMM; kg, body fat mass (BFM; kg, and visceral fat area (VFA; cm2 were obtained from bioelectrical analysis. Then, the following values were calculated as follows: percent of SMM (SMM%; %: SMM (kg/weight (kg, skeletal muscle index (SMI; kg/m2: SMM (kg/height (m2, skeletal muscle to body fat ratio (MFR: SMM (kg/BFM (kg, and skeletal muscle to visceral fat ratio (SVR; kg/cm2: SMM (kg/VFA (cm2.ResultsAmong 838 subjects, 88 (10.5% were newly diagnosed with MS. Development of MS increased according to increasing quintiles of BMI, SMM, VFA, and SMI, but was negatively associated with SMM%, MFR, and SVR. VFA was positively associated with high waist circumference (WC, high blood pressure (BP, dysglycemia, and high triglyceride (TG. In contrast, MFR was negatively associated with high WC, high BP, dysglycemia, and high TG. SVR was negatively associated with all components of MS.ConclusionRelative SMM ratio to body composition, rather than absolute mass, may play a critical role in development of MS and could be used as a strong predictor.

    Studies indicate that those participating in sports are a high-risk population for hazardous alcohol use. Previous research identifies psychosocial drivers underpinning this link between sports participation and risky drinking behavior; however, the evidence is restricted to cross-sectional prevalence studies. Theoretical evaluations suggest that psychologically constructed identities are a defining factor for behaviors in this context. Therefore, the present study sought to examine longitudinally the relationships among sports-related identities, well-being, and alcohol behaviors in those participating in sports. Respondents completed self-report questionnaires on their alcohol consumption, drinking motives, athlete identity (personal identity), sports group identification (social identity), and general well-being. A sample of 475 participants (male = 55.6%; mean age = 20.2 years) provided data at Time 1 for cross-sectional analysis. Longitudinal associations were conducted with 92 participants (male = 42.4%; mean age = 20.8 years) who provided follow-up data (Time 1 and 6 months later). Cross-sectional results revealed an association between social identity and alcohol consumption, which was fully mediated by positive reinforcement drinking motives. Correlation analysis found a significant positive relationship between Time 1 alcohol consumption and social identity 6 months later. Furthermore, social identity was positively associated with consumption, whereas athlete identity was negatively associated therewith. Finally, well-being was positively associated only with sports group identification over time. Our findings suggest that sport-related drinking may be an avenue for building group identification, and this identification is linked to well-being.

    To identify the source (press releases or news) of distortions, exaggerations, or changes to the main conclusions drawn from research that could potentially influence a reader's health related behaviour. Retrospective quantitative content analysis. Journal articles, press releases, and related news, with accompanying simulations. Press releases (n = 462) on biomedical and health related science issued by 20 leading UK universities in 2011, alongside their associated peer reviewed research papers and news stories (n = 668). Advice to readers to change behaviour, causal statements drawn from correlational research, and inference to humans from animal research that went beyond those in the associated peer reviewed papers. 40% (95% confidence interval 33% to 46%) of the press releases contained exaggerated advice, 33% (26% to 40%) contained exaggerated causal claims, and 36% (28% to 46%) contained exaggerated inference to humans from animal research. When press releases contained such exaggeration, 58% (95% confidence interval 48% to 68%), 81% (70% to 93%), and 86% (77% to 95%) of news stories, respectively, contained similar exaggeration, compared with exaggeration rates of 17% (10% to 24%), 18% (9% to 27%), and 10% (0% to 19%) in news when the press releases were not exaggerated. Odds ratios for each category of analysis were 6.5 (95% confidence interval 3.5 to 12), 20 (7.6 to 51), and 56 (15 to 211). At the same time, there was little evidence that exaggeration in press releases increased the uptake of news. Exaggeration in news is strongly associated with exaggeration in press releases. Improving the accuracy of academic press releases could represent a key opportunity for reducing misleading health related news. © Sumner et al 2014.

    Previous research has shown that lymphoedema impacts negatively on an individual, including psychological distress and body image disturbance, particularly for younger women. This study identified psychological factors associated with distress in women with breast cancer-related lymphoedema and determined whether age moderated the specific relationship between body image disturbance and distress. Australian women (n = 166) diagnosed with breast cancer-related lymphoedema were recruited through a community-based breast cancer organisation and lymphoedema treatment clinics. Participants completed an online survey assessing lymphoedema-related cognitions (personal control, perceived treatment effectiveness, and consequences of lymphoedema), perceived ability to self-regulate lymphoedema-related negative affect, body image disturbance, psychological distress (depression, anxiety and stress), and demographic/medical information. Beliefs about the consequences, perceived effectiveness of treatment and controllability of lymphoedema, perceived ability to self-regulate negative affect, body image disturbance, and number of lymphoedema symptoms were correlated with depression, anxiety, and stress scores. Multivariate regression analyses indicated that body image disturbance was significantly associated with depression, anxiety, and stress, and perceived treatment effectiveness was associated with stress. Age was a significant moderator of the relationship between body image disturbance and depression and anxiety, with older women with greater body image disturbance more distressed. Health professionals need to be aware that women diagnosed with lymphoedema are at risk of experiencing psychological distress, particularly arising from body image disturbance and beliefs that treatment cannot control lymphoedema. Furthermore, older women may be at an increased risk of anxiety and depression arising from body image disturbance. Copyright © 2015 John Wiley & Sons, Ltd

    The purpose of this study was to describe the workplace environments of young adults and examine associations with diet, physical activity (PA) and body mass index (BMI). Cross-sectional data were collected (2008-2009) from 1538 employed young adult participants in Project EAT (Eating and Activity among Teens and Young Adults), a diverse population-based sample. Survey measures assessed height, weight, diet, moderate-to-vigorous PA, transportation-related PA and perceptions of the workplace food and PA environments (eg, soda availability, coworker support). Healthful characteristics were summed to reflect overall workplace healthfulness. Modified Poisson regression analyses conducted in 2015 identified associations between workplace food and PA environments and diet, PA and BMI. The healthfulness of workplace environments was suboptimal. Greater exposure to healthful workplace characteristics was related to more young adults engaged in favourable diet and PA behaviours and a lower prevalence obesity. For example, adjusted rates of obesity were 24% and 17% among those reporting low (≤1 characteristic) versus high (≥3 characteristics) exposure to healthful food environments, respectively (p<0.05). Workplace characteristics independently associated with weight-related outcomes included soda availability, proximity to a fast food outlet, living close to work and perceived ease of eating a healthy diet or being active at work. A more healthful workplace environment overall, including physical attributes and perceived social norms, may contribute to more favourable weight-related behaviours and lower prevalence of obesity among young adults. Employer-initiated and community-initiated policies may represent one way to create healthier workplace environments for young adults. Published by the BMJ Publishing Group Limited.

    This study aimed to (1) describe the Quality of Working Life (QWL) of cancer survivors and (2) explore associations between the QWL of cancer survivors and health- and work-related variables. Employed and self-employed cancer survivors were recruited through hospitals and patient organizations. They completed the Quality of Working Life Questionnaire for Cancer Survivors (QWLQ-CS) and health- and work-related variables in this cross-sectional study. The QWL scores of cancer survivors were described, and associations between QWL and health- and work-related variables were assessed. The QWLQ-CS was completed by 302 cancer survivors (28% male) with a mean age of 52 ± 8 years. They were diagnosed between 0 and 10 years ago with various types of cancer, such as breast cancers, gastrointestinal cancers, urological cancers, and haematological cancers. The QWL mean score of cancer survivors was 75 ± 12 (0-100). Cancer survivors had statistically significant lower QWL scores when they had been treated with chemotherapy or when they reported co-morbidity (p ≤ 0.05). Cancer survivors without managerial positions, with low incomes or physically demanding work, and who worked a proportion of their contract hours had statistically significantly lower QWL scores (p ≤ 0.05). This study described the QWL of cancer survivors and associations between QWL and health- and work-related variables. Based on these variables, it is possible to indicate groups of cancer survivors who need more attention and support regarding QWL and work continuation.

    Full Text Available Antiretroviral therapy has led to a decrease in HIV-related mortality and to the emergence of non-AIDS defining diseases as competing causes of death. This study estimates the HIV mortality rate and their risk factors with regard to different causes in a large city from January 2001 to June 2013.We followed-up 3137 newly diagnosed HIV non-AIDS cases. Causes of death were classified as HIV-related, non-HIV-related and external. We examined the effect of risk factors on survival using mortality rates, Kaplan-Meier plots and Cox models. Finally, we estimated survival for each main cause of death groups through Fine and Gray models.182 deaths were found [14.0/1000 person-years of follow-up (py; 95% confidence interval (CI:12.0-16.1/1000 py], 81.3% of them had a known cause of death. Mortality rate by HIV-related causes and non-HIV-related causes was the same (4.9/1000 py; CI:3.7-6.1/1000 py, external was lower [1.7/1000 py; (1.0-2.4/1000 py].Kaplan-Meier estimate showed worse survival in intravenous drug user (IDU and heterosexuals than in men having sex with men (MSM. Factors associated with HIV-related causes of death include: IDU male (subHazard Ratio (sHR:3.2; CI:1.5-7.0 and <200 CD4 at diagnosis (sHR:2.7; CI:1.3-5.7 versus ≥500 CD4. Factors associated with non-HIV-related causes of death include: ageing (sHR:1.5; CI:1.4-1.7 and heterosexual female (sHR:2.8; CI:1.1-7.3 versus MSM. Factors associated with external causes of death were IDU male (sHR:28.7; CI:6.7-123.2 and heterosexual male (sHR:11.8; CI:2.5-56.4 versus MSM.There are important differences in survival among transmission groups. Improved treatment is especially necessary in IDUs and heterosexual males.

    Are severe depressive symptoms in women and men associated with individual and dyadic infertility-related stress in couples undergoing infertility treatment? Severe depressive symptoms were significantly associated with increased infertility-related distress at both the individual and partner level. WHAT IS KNOWN ALREADY?: An infertility diagnosis, the stress of medical treatments and a prior history of depression are risk factors for future depression in those undergoing fertility treatments. Studies examining the impact of severe depressive symptoms on infertility-related distress in couples are lacking. This cross-sectional study included 1406 couples who were consecutively referred patients undergoing fertility treatments in Denmark in the year 2000. A total of 1049 men and 1131 women were included in the study. Participants were consecutively referred patients undergoing a cycle of medically assisted reproduction treatment at five Danish public and private clinics specializing in treating fertility patients. Severe depressive symptoms were measured by the Mental Health Inventory 5 from the Short Form Health Survey 36. Infertility distress was measured by the COMPI Fertility Problem Stress Scales. Multilevel modelling using the actor-partner interdependence model was used to study the couple as the unit of analysis. Severe depressive symptoms were reported in 11.6% of women and 4.3% of men, and were significantly associated with increased infertility-related distress at the individual and partner level. There was no significant interaction for gender indicating that men and women did not differ in how severe depressive symptoms were associated with infertility distress. Because of the cross-sectional study design, the study findings only show an association between severe depressive symptoms to individual and partner distress at a single point in time; however, nothing is known about causality. This study adds to the growing body of literature using the couple

    The 5-year survival rate for breast cancer among Korean women has increased steadily; however, breast cancer remains the leading cause of cancer mortality among women. One-carbon metabolism, which requires an adequate supply of methyl group donors and B vitamins, may affect the prognosis of breast cancer. This aim of this study was to investigate the associations of dietary intake of vitamin B2, vitamin B6 and folate before diagnosis on the prognosis of breast cancer. We assessed the dietary intake using a food frequency questionnaire with 980 women who were newly diagnosed and histopathologically confirmed to have primary breast cancer from hospitals in Korea, and 141 disease progression events occurred. Cox's proportional hazard regression models were used to estimate the hazard ratio (HR) and 95% confidence interval (95% CI) adjusting for age, education, recruitment sites, TNM stage, hormone status, nuclear grade and total calorie. There was no significant association between any one-carbon metabolism related nutrients (vitamin B2, B6 and folate) and the progression of breast cancer overall. However, one-carbon metabolism related nutrients were associated with disease progression in breast cancer patients stratified by subtypes. In ER + and/or PR + breast cancers, no association was observed; however, in ER-/PR- breast cancers, a high intake of vitamin B2 and folate statistically elevated the HR of breast cancer progression (HR = 2.28; 95% CI, 1.20-4.35, HR = 1.84; 95% CI, 1.02-3.32, respectively) compared to a low intake. This positive association between the ER/PR status and progression of the disease was profound when the nutrient intakes were categorized in a combined score (Pinteraction = 0.018). In ER-/PR- breast cancers, high combined scores were associated with a significantly poor DFS compared to those belonging to the low score group (HR = 3.84; 95% CI, 1.70-8.71). In conclusion, our results suggest that one-carbon related nutrients have a role in the

    Truancy is a serious concern in the United States. Its negative effects are so pervasive that in 2003 the Office of Juvenile Justice and Delinquency Prevention named truancy prevention a national priority. Effective prevention of truancy requires a thorough understanding of the characteristics that describe truant youth as well as factors that may put them at risk for truancy. Unfortunately, surprisingly little is known about the correlates and/or causes of truancy. In this paper we explore associations between truancy and several salient school-related risk and protective factors among a sample of youth who grew up in socially disorganized neighborhoods of Denver, CO. We demonstrate that several school-related risk and protective factors are associated with truancy. Perhaps most importantly, we identify that the two most robust predictors are school performance and involvement with delinquent peers, and that these two variables form a synergistic relationship in which the relationship between delinquent peer association and truancy is mitigated among students who perform well in school. EDITORS' STRATEGIC IMPLICATIONS: The authors use data from a large probability sample drawn from neighborhoods with high crime rates to identify key correlates of truancy. They also draw attention to the dearth of efficacious truancy prevention efforts in spite of the magnitude of the problem.

    Adolescents are at heightened risk for the development of both depressive and substance-related disorders. These two disorders frequently co-occur in adolescents and are associated with significant morbidity and mortality. Given the substantial economic and psychosocial burden associated with the comorbid condition, the identification of causal mechanisms associated with their co-occurrence is of great public health importance. Although there is significant understanding of the environmental and neurobiological factors involved in depression and addictive disorders considered separately, the mechanisms underlying the comorbid illness have not been investigated carefully. The purpose of this review is to summarize the extant literature on genetic, environmental and neurobiological processes involved in the etiology of depressive and substance-related disorders in adolescents and adults. It is important to note that the data on common neurobiological systems that link addictive and depressive disorders are primarily from research with adult animals and humans. Given the ongoing maturation of these systems throughout adolescence and early adult life, it is not clear how these neurobiological processes influence the development and progression of both disorders. A better understanding of the pathophysiological mechanisms leading to the onset and course of these disorders during adolescence will be helpful in developing more effective preventive and treatment strategies not only for this population but also for adult patients with early-onset illness.

    Agents that modulate immune checkpoint proteins, such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death receptor-1 (PD-1), have become a mainstay in cancer treatment. The clinical benefit afforded by immune checkpoint inhibitors can be accompanied by immune-related adverse events (irAE) that affect the skin, gastrointestinal tract, liver, and endocrine system. The types of irAEs associated with immune checkpoint inhibitors are generally consistent across tumor types. Immune-related endocrine events can affect the pituitary, thyroid, and adrenal glands, as well as other downstream target organs. These events are unique when compared with other irAEs because the manifestations are often irreversible. Immune-related endocrine events are typically grade 1/2 in severity and often present with non-specific symptoms, making them difficult to diagnose. The mechanisms underlying immune-related target organ damage in select individuals remain mostly undefined. Management includes close patient monitoring, appropriate laboratory testing for endocrine function, replacement of hormones, and consultation with an endocrinologist when appropriate. An awareness of the symptoms and management of immune-related endocrine events may aid in the safe and appropriate use of immune checkpoint inhibitors in clinical practice.

    Sleep-related experiences [Watson, D. (2001). Dissociations of the night: Individual differences in sleep-related experiences and their relation to dissociation and schizotypy. Journal of Abnormal Psychology, 110, 526-535] refer to a host of nocturnal altered-consciousness phenomena, including narcoleptic tendencies, nightmares, problem-solving dreams, waking dreams, and lucid dreams. In an attempt to clarify the meaning of this construct, we examined cross-sectional and longitudinal associations of sleep-related experiences (SREs), altered-consciousness tendencies (i.e., dissociation and transliminality), psychological distress, childhood maltreatment (i.e., abuse and neglect), and life stress in young adults. Both types of SREs (general SREs and lucid dreaming) were found to be distinguishable from altered-consciousness tendencies. Transliminality emerged as a longitudinal predictor of both general SREs and lucid dreams. Psychological distress and an increase in life stress predicted an increase in general SREs over a 3-month interval. We conclude that transliminality is a general altered-consciousness trait that accounts for some of the individual differences in sleep-related experiences, and that general sleep experiences are an outcome of psychological distress and life stress.

    Full Text Available The aim of the present study was to identify the game-related statistics that allow discriminating between starters and nonstarter players in women's basketball when related to winning or losing games and best or worst teams. The sample comprised all 216 regular season games from the 2005 Women's National Basketball Association League (WNBA. The game-related statistics included were 2- and 3- point field-goals (both successful and unsuccessful, free-throws (both successful and unsuccessful, defensive and offensive rebounds, assists, blocks, fouls, steals, turnovers and minutes played. Results from multivariate analysis showed that when best teams won, the discriminant game-related statistics were successful 2-point field-goals (SC = 0.47, successful free-throws (SC = 0.44, fouls (SC = -0.41, assists (SC = 0.37, and defensive rebounds (SC = 0.37. When the worst teams won, the discriminant game-related statistics were successful 2-point field- goals (SC = 0.37, successful free-throws (SC = 0.45, assists (SC = 0.58, and steals (SC = 0.35. The results showed that the successful 2-point field-goals, successful free-throws and the assists were the most powerful variables discriminating between starters and nonstarters. These specific characteristics helped to point out the importance of starters' players shooting and passing ability during competitions

    Because loneliness is a subjective experience, it is often examined using self-reports. Yet, researchers have started to use other-reports to examine loneliness. As previous research suggests that discrepancies between self- and other views might have important implications for adolescents' mental health, the current study examines discrepancies in multi-informant reports on adolescents' loneliness in relation with prosocial behavior, aggression, and adolescents' parent-related loneliness. The sample consisted of 374 mother-adolescent dyads and 318 father-adolescent dyads (41.80% male, M age  = 15.67 years, SD = 1.25). Results indicated that informants used different reference points to assess adolescents' peer-related loneliness, but were otherwise comparable. Moreover, informant discrepancies were associated with greater adolescents' reported parent-related loneliness. The current study did not provide evidence that discrepancies were related to prosocial or aggressive behavior. The current study adds to the notion that other-reports on loneliness show substantial convergence with self-reports. In addition, this study indicates that the discrepancy between other- and self-reports on loneliness holds valuable information for adolescent socio-emotional adjustment.

    Periodontal disease is a chronic disease caused by bacterial infection, and frequently develops in adulthood. As the disease is closely related to lifestyle, it is important to clarify its relationship with health-related behaviors to provide effective health instructions targeting its prevention. In this study, we focused on periodontal pockets with advanced periodontal disease to clarify the health-related behaviors associated with the presence or absence of periodontal pockets. The subjects were 3,142 employees (male: N=2,429, female: N=713; 42.4 ± 10.5 years, Range 20-59 years) of one company, which had provided all employees with an oral health program in 2002. Participants with a Community Periodontal Index code of ≤2 and ≥3 were classified as those without and with periodontal pockets, respectively. To clarify the health-related behaviors associated with the presence or absence of periodontal pockets, we conducted multivariate logistic regression analysis, with presence/absence of periodontal pockets as the dependent variable, and items of health-related behavior investigated in 2002 as independent variables, and calculated the odds ratios (OR) and 95% confidence intervals (95%CI) adjusted for sex, age group and occupation. The factor most strongly correlated with the presence of periodontal pockets was non-use of dental floss (OR=1.95 (95%CI: 1.57-2.41)), followed by smoking (OR=1.71 (95%CI: 1.44-2.03)), and tooth-brushing habits (≤once a day: OR=1.33 (95%CI: 1.10-1.61)). Our results suggest that, to promote oral health program at the worksite, it is important to provide health education and instructions to encourage the use of dental floss, a daily tooth-brushing habit, and smoking cessation.

    Inflammatory bowel disease (IBD) usually develops at a young age, and many women experience marriage, pregnancy, and delivery during the disease course. We aimed to evaluate the pregnancy-related knowledge of women with IBD in Korea and investigate the associated factors. A total of 270 women with IBD, aged 19-45 years, from four tertiary hospitals in Korea were administered a questionnaire comprising 17 questions from the validated Crohn's and Colitis Pregnancy Knowledge Score (CCPKnow) that were translated into Korean. The average CCPKnow score of the 270 patients was 7.47 ± 3.07; and most of the patients (51.5%) exhibited a poor knowledge level. Younger age at diagnosis, Crohn's disease rather than ulcerative colitis, longer disease duration, anti-TNF-α medication history, higher household income, and delivery after diagnosis were associated with an appropriate level of pregnancy-related knowledge. Younger age at diagnosis (odds ratio [OR], 1.87; p = .036), anti-TNF-α therapy (OR, 1.87; p = .047), and delivery while suffering from IBD (OR, 3.07; p = .002) were independent factors affecting the pregnancy-related knowledge level. Approximately 69.6% of patients acquired related knowledge from their gastroenterology doctor, whereas 19.4% of patients intended to remain childless. To our knowledge, this is the first study to assess the pregnancy-related knowledge of women of reproductive-age with IBD and their perceptions by using a questionnaire in Asia. As more than half of the patients showed a poor knowledge level of IBD, a general education program should be conducted by gastroenterology doctors.

    Full Text Available Background: White matter changes (WMC are a common finding among older adults and patients with Parkinson's disease (PD, and have been associated with, e.g., gait deficits and executive dysfunction. How the factors age and PD influence WMC-related deficits is, to our best knowledge, not investigated to date. We hypothesized that advanced age and presence of PD leads to WMC-related symptoms while practicing tasks with a low complexity level, and low age and absence of PD leads to WMC-related symptoms while practicing tasks with a high complexity level.Methods: Hundred and thirty-eight participants [65 young persons without PD (50–69 years, yPn, 22 young PD patients (50–69 years, yPD, 36 old persons without PD (70–89 years, oPn and 15 old PD patients (70–89 years, oPD] were included. Presence and severity of WMC were determined with the modified Fazekas score. Velocity of walking under single and dual tasking conditions and the Trail Making Test (TMT were used as gait and executive function parameters. Correlations between presence and severity of WMC, and gait and executive function parameters were tested in yPn, yPD, oPn, and oPD using Spearman's rank correlation, and significance between groups was evaluated with Fisher's z-transformed correlation coefficient.Results: yPn and yPD, as well as oPn and oPD did not differ regarding demographic and clinical parameters. Severity of WMC was not significantly different between groups. yPn and yPD displayed significant correlations of WMC with executive function parameters at low levels of task complexity, oPn at intermediate, and oPD at high complexity levels.Conclusion: This study argues for a relevant association of age and PD-related brain pathology with WMC-related gait and executive function deficits.

    Full Text Available Introduction. University students are subjected to different kinds of stressors, i.e. academic pressures, social issues and financial problems. This can affect their academic achievements and quality of life. Objective. The aim of this study was to determine the health-related quality of life of university students, and how it is affected by the presence of chronic diseases, mental disorders comorbidity, and patterns of medical services’ use. Methods. This web-based study included a sample of 1,410 Slovenian university students. We used a self-administered questionnaire, containing a sheet with demographic data, Zung’s self-assessment inventories about anxiety and depression, and EQ-5D questionnaire. The main outcome measures were scores on EQ-5D part and VAS part of the EQ-5D questionnaire. Results. Independent factors associated with the health-related quality of life of university students, were the presence of chronic pain, the presence of depression and anxiety, need for urgent medical help and at least one visit to a clinical specialist in the past year. The independent factors associated with the health status of university students were the presence of chronic diseases, chronic pain, depression and anxiety, a visit to a clinical specialist, a need for urgent medical help and a visit to an emergency unit in the past year. Conclusion. Health-related quality of life of university students can be seriously affected by the presence of mental disorders and chronic pain. Appropriate health-related measures should be adopted to achieve early recognition of worse health-related quality of life, the presence of mental disorders and other chronic conditions, and to enable their effective treatment.

    This paper reviews the data of Frank et al. in the light of increasing concern over the safety of contact lenses used for extended wear. Relative risks were calculated for four types of contact lenses (CLs): extended wear soft, daily wear soft, rigid gas-permeable (RGP), and polymethylmethacrylate (PMMA) lenses--worn by a group of patients who presented themselves for emergency ocular treatment. The cases comprised 329 CL wearers who were found to have lens related metabolic disorders, toxic or hypersensitivity reactions, cornea abrasions, microbial keratitis, or some other lens-induced problem. Controls comprised 64 CL wearers whose ocular problems were unrelated to lens use. It was found that extended wear soft lenses were nearly 7 times more likely to be associated with an ocular disorder than PMMA hard lenses, and approximately 3.4 times more likely than daily wear soft lenses. Furthermore, extended wear soft lenses were nearly 5 times more likely to be linked with microbial keratitis than daily wear soft lenses, and approximately 7.5 times more likely than RGP lenses. Metabolic disorders were also more common with extended wear lenses (relatively risk: 3.3) than with either RGP (1.8) or daily wear soft lenses (2.0) or PMMA lenses (1.0). If the association between extended wear soft lenses and ocular complications is borne out in large population studies, eye-care professionals may need to reconsider the wisdom of prescribing these lenses for the cosmetic correction of vision.

    Internet addiction (including online gaming) has been associated with depression. However, most prior research relating internet addiction symptomatology to depressive symptoms has been cross-sectional, conducted with children and adolescents, and only examined depressive symptoms as a broad construct. The purpose of the current study was to examine potential longitudinal associations between anhedonia (i.e., difficulty experiencing pleasure, a key facet of depression) and internet-related addictive behaviors in 503 at-risk emerging adults (former attendees of alternative high schools). Participants completed surveys at baseline and approximately one year later (9-18 months later). Results indicated that trait anhedonia prospectively predicted greater levels of compulsive internet use and addiction to online activities as well as a greater likelihood of addiction to online/offline video games. These findings suggest that anhedonia may contribute to the development of internet-related addictive behaviors in the emerging adult population. Thus, interventions that target anhedonia in emerging adulthood (e.g., bupropion treatment or behavioral activation therapy) may help prevent or treat internet addiction.

Individuals with BMI Older adults with higher, more favourable DST scores were significantly more likely to be food sufficient, report eating breakfast, have no chewing difficulties and report no decline in intake in the previous 6 months. The DST may identify potential targets for improving diet quality in older adults including promotion of healthy BMI, breakfast consumption, improving dentition and identifying strategies to decrease concern about food sufficiency.

  8. Fibrinogen and clot-related phenotypes determined by fibrinogen polymorphisms: Independent and IL-6-interactive associations.

    Directory of Open Access Journals (Sweden)

    H Toinét Cronjé

    Full Text Available Interleukin-6 (IL-6 induces the expression of fibrinogen, and polymorphic variation within the fibrinogen genes is believed to alter the magnitude of this expression. The identification of the functional relevance of individual fibrinogen single nucleotide polymorphisms (SNPs has been hindered by the high linkage disequilibrium (LD reported in the European fibrinogen gene locus. This study investigated two novel and 12 known fibrinogen SNPs of potential functional relevance, in 2010 Tswana individuals known to have low LD. We aimed to identify functional polymorphisms that contribute to clot-related phenotypes and total and γ' fibrinogen concentrations independently and through their interaction with IL-6, by taking advantage of the high fibrinogen and IL-6 concentrations and the low LD reported in black South Africans. Fibrinogen was significantly associated with IL-6, thereby mediating associations of IL-6 with clot formation and structure, although attenuating the association of IL-6 with clot lysis time. None of the common European fibrinogen haplotypes was present in this study population. Putative functional fibrinogen SNPs FGB-rs7439150, rs1800789 (-1420G/A and rs1800787 (-148C/T were significantly associated with fibrinogen concentration and altered clot properties, with several associations significantly influenced by IL-6 concentrations. The impact of harbouring several minor fibrinogen SNP alleles on the association of IL-6 and fibrinogen concentration was cumulative, with possession of each additional minor allele showing a stronger relationship of IL-6 with fibrinogen. This was also reflected in differences in clot properties, suggesting potential clinical relevance. Therefore, when investigating the effect of fibrinogen genetics on fibrinogen concentrations and CVD outcome, the possible interactions with modulating factors and the fact that SNP effects seem to be additive should be taken into account.

    The objective of the study is to investigate the prevalence of electrolyte imbalance (EI) in the emergency department (ED) with systemic diseases in different decades of life. We enrolled patients admitted to the ED. The population study included 7941 patients, subdivided in 3 groups: young group (Y), middle-aged group (MA), and elderly group (E). We observed EI in 13.7% of the whole population. Hyponatremia (hNa(+)) is the most frequent EI (44%) followed by hypokalemia (hK(+)) (39%), hyperkalemia (HK(+)) (13%), and hypernatremia (HNa(+)) (4.4%). In the Y group, the EI occurred in 7.1% of all patients (P< .05 vs MA and E), whereas in the MA group, they were shown in 11.5% of patients and in the E group in 22% of all patients group (P< .05 vs MA and Y). In the Y group, gastrointestinal diseases are the most frequently associated disease (24.6%; P< .05 vs MA and E). In the MA group, the most frequently associated disease was a current cardiovascular disease (29.7%; P< .05 vs Y and E). In the E group, the frequently associated diseases are cardiovascular (22.8%; P< .05 vs Y) and lung diseases (16.7%; P< .05 vs MA and Y). In our study, 13.7% of all patients showed an EI, and only 2% of cases were alone without any associated systemic disease. Most EIs are associated to other systemic diseases. The present data also depict different age-related and disease-associated prevalence patterns of EI, thus highlighting a complex clinical scenario. Copyright © 2016. Published by Elsevier Inc.

    Several susceptibility genes have been proposed for dyslexia (reading disability; RD) and specific language impairment (SLI). RD and SLI show comorbidity, but it is unclear whether a common genetic component is shared. We have investigated whether candidate genes for RD and SLI affect specific cognitive traits or have broad effect on cognition. We have analyzed common risk variants within RD (MRPL19/C2ORF3, KIAA0319, and DCDC2) and language impairment (CMIP and ATP2C2) candidate loci in the Avon Longitudinal Study of Parents and Children cohort (n = 3725), representing children born in southwest England in the early 1990s. We detected associations between reading skills and KIAA0319, DCDC2, and CMIP. We show that DCDC2 is specifically associated with RD, whereas variants in CMIP and KIAA0319 are associated with reading skills across the ability range. The strongest associations were restricted to single-word reading and spelling measures, suggesting that these genes do not extend their effect to other reading and language-related skills. Inclusion of individuals with comorbidity tends to strengthen these associations. Our data do not support MRPL19/C2ORF3 as a locus involved in reading abilities nor CMIP/ATP2C2 as genes regulating language skills. We provide further support for the role of KIAA0319 and DCDC2 in contributing to reading abilities and novel evidence that the language-disorder candidate gene CMIP is also implicated in reading processes. Additionally, we present novel data to evaluate the prevalence and comorbidity of RD and SLI, and we recommend not excluding individuals with comorbid RD and SLI when designing genetic association studies for RD.

    Full Text Available Kawasaki disease (KD is a pediatric vasculitis that damages the coronary arteries in 25% of untreated and approximately 5% of treated children. Epidemiologic data suggest that KD is triggered by unidentified infection(s in genetically susceptible children. To investigate genetic determinants of KD susceptibility, we performed a genome-wide association study (GWAS in 119 Caucasian KD cases and 135 matched controls with stringent correction for possible admixture, followed by replication in an independent cohort and subsequent fine-mapping, for a total of 893 KD cases plus population and family controls. Significant associations of 40 SNPs and six haplotypes, identifying 31 genes, were replicated in an independent cohort of 583 predominantly Caucasian KD families, with NAALADL2 (rs17531088, p(combined = 1.13 x 10(-6 and ZFHX3 (rs7199343, p(combined = 2.37 x 10(-6 most significantly associated. Sixteen associated variants with a minor allele frequency of >0.05 that lay within or close to known genes were fine-mapped with HapMap tagging SNPs in 781 KD cases, including 590 from the discovery and replication stages. Original or tagging SNPs in eight of these genes replicated the original findings, with seven genes having further significant markers in adjacent regions. In four genes (ZFHX3, NAALADL2, PPP1R14C, and TCP1, the neighboring markers were more significantly associated than the originally associated variants. Investigation of functional relationships between the eight fine-mapped genes using Ingenuity Pathway Analysis identified a single functional network (p = 10(-13 containing five fine-mapped genes-LNX1, CAMK2D, ZFHX3, CSMD1, and TCP1-with functional relationships potentially related to inflammation, apoptosis, and cardiovascular pathology. Pair-wise blood transcript levels were measured during acute and convalescent KD for all fine-mapped genes, revealing a consistent trend of significantly reduced transcript levels prior to treatment

To investigate genetic determinants of KD susceptibility, we performed a genome-wide association study (GWAS) in 119 Caucasian KD cases and 135 matched controls with stringent correction for possible admixture, followed by replication in an independent cohort and subsequent fine-mapping, for a total of 893 KD cases plus population and family controls. Significant associations of 40 SNPs and six haplotypes, identifying 31 genes, were replicated in an independent cohort of 583 predominantly Caucasian KD families, with NAALADL2 (rs17531088, p combined = 1.13×10−6) and ZFHX3 (rs7199343, p combined = 2.37×10−6) most significantly associated. Sixteen associated variants with a minor allele frequency of >0.05 that lay within or close to known genes were fine-mapped with HapMap tagging SNPs in 781 KD cases, including 590 from the discovery and replication stages. Original or tagging SNPs in eight of these genes replicated the original findings, with seven genes having further significant markers in adjacent regions. In four genes (ZFHX3, NAALADL2, PPP1R14C, and TCP1), the neighboring markers were more significantly associated than the originally associated variants. Investigation of functional relationships between the eight fine-mapped genes using Ingenuity Pathway Analysis identified a single functional network (p = 10−13) containing five fine-mapped genes—LNX1, CAMK2D, ZFHX3, CSMD1, and TCP1—with functional relationships potentially related to inflammation, apoptosis, and cardiovascular pathology. Pair-wise blood transcript levels were measured during acute and convalescent KD for all fine-mapped genes, revealing a consistent trend of significantly reduced transcript levels prior to treatment

    BACKGROUND: Obesity is the cause of other chronic diseases, psychological problems, obesity shortens the lifespan and puts strain on health systems. The risk associated with childhood obesity in particular, which will accelerate the development of adult morbidity and mortality, has been identified as an emerging public health problem. METHODS: To estimate the length of stay and associated hospital costs for obesity related illnesses a cost of illness study was set up. All discharges from all acute hospitals in the Republic of Ireland from 1997 to 2004 with a principal or secondary diagnostic code for obesity for all children from 6 to 18 years of age and for adults were collected.A discharge frequency was calculated by dividing obesity related discharges by the total number of diagnoses (principal and secondary) for each year. The hospital costs related to obesity was calculated based on the total number of days care. RESULTS: The discharge frequency of obesity related conditions increased from 1.14 in 1997 to 1.49 in 2004 for adults and from 0.81 to 1.37 for children. The relative length of stay (number of days in care for obesity related conditions per 1000 days of hospital care given) increased from 1.47 in 1997 to 4.16 in 2004 for children and from 3.68 in 1997 to 6.74 in 2004 for adults.Based on the 2001 figures for cost per inpatient bed day, the annual hospital cost was calculated to be 4.4 Euromillion in 1997, increasing to 13.3 Euromillion in 2004. At a 20% variable hospital cost the cost ranges from 0.9 Euromillion in 1997 to 2.7 Euromillion in 2004; a 200% increase. CONCLUSION: The annual increase in the proportion of hospital discharges related to obesity is alarming. This increase is related to a significant increase in economic costs. This paper emphasises the need for action at an early stage of life. Health promotion and primary prevention of obesity should be high on the political agenda.

    To determine the associations between endodontic factors and oral health-related quality of life (OHQoL), controlling for socio-demographics, pain and other oral health clinical factors. OHQoL assessments were conducted amongst a consecutive sample of 412 Chinese patients requiring endodontic treatment employing the short-form Oral Heath Impact Profile (OHIP-14). Information on (i) number of teeth requiring endodontic treatment, (ii) tooth type, (iii) retreatment requirements, (iv) periapical radiolucency assessment and (v) diagnostic classification was obtained. In addition, socio-demographic information (age, gender, educational attainment and family income), pain ratings on a visual analogue scale (VAS) and other clinical oral health status information were collected. Bivariate analyses identified association between number of teeth requiring endodontic treatment and summary OHIP-14 score (P endodontic retreatment was associated with summary OHIP-14 score (P endodontic treatment for multiple teeth were more than twice as likely to have poor OHQoL (upper quintile OHIP-14 scores) compared with those requiring endodontic treatment for a single tooth (OR = 2.16, 95% CI 1.17, 3.98, P endodontic treatment.

    Full Text Available Our study examined the relationships of relational pronouns used in parental conversation to the quality of early family interactions, as indexed by Family Alliance (FA. We hypothesized that more positive family interactions were associated with the use of more we-pronouns (e.g., we, us, our; we-ness and fewer I- and you-pronouns (e.g., I, me, you, your; separateness by both mothers and fathers. Our statistical model using a multilevel modelling framework and two levels of analysis (i.e., a couple level and an individual level was tested on 47 non-referred families (n = 31 primiparous families; child’s age, M = 15.75 months, SD = 2.73 with we-ness and separateness as outcomes and FA functions as between-dyads variables. Analyses revealed that we-ness within the parental couple was only positively associated with family affect sharing while separateness was negatively associated with different FA functions (e.g., communication mistakes. Our main finding suggested that the kinds of personal pronouns used by parental couples when discussing children’s education would be associated to the emotional quality of the family interactions.

    Drawing on 5 waves of multiple-informant data gathered from focal participants and their parents and intimate partners (n = 360 families) who completed annual surveys in the German Family Panel (pairfam) study, the present investigation examined bidirectional associations between the development of adults' conflictual and intimate interactions with their parents and intimate partners. Autoregressive cross-lagged latent change score modeling results revealed a robust pattern of coordinated development between parent-adult child and couple conflictual and intimate interactions: increases in conflict and intimacy in one relationship were contemporaneously intertwined with changes in the other relationship. Additionally, prior couple intimacy and conflict predicted future parent-adult child relations in 7 out of 14 cross-lagged pathways examined, but parent-adult child conflict and intimacy was only associated with future couple interactions in 1 pathway. These associations were not moderated by the gender of parents or the adult child or whether the adult child was a young adult or nearing midlife. Frequency of contact between parents and the adult child moderated some associations. Adults simultaneously juggle ties with parents and intimate partners, and this study provides strong evidence supporting the coordinated development of conflictual and intimate patterns of interaction in each relationship.

    Full Text Available Systemic lupus erythematosus (SLE is an autoimmune inflammatory disease, and environmental factors are proposed to exacerbate existing symptoms. One such environmental factor is mercury. The aim of this study was to investigate the relationship between exposure to mercury (Hg and disease activity and disease associated damage in Total Hg concentrations in hair and urine were measured in 52 SLE patients. Dental amalgams were quantified. Disease activity was assessed using three indexes including the British Isles Lupus Assessment Group Index (BILAG. Disease associated damage was measured using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology SLICC/ACR Damage Index. Pearson’s correlation identified a significant negative correlation between hair Hg and BILAG (r = −0.323, p = 0.029 and SLICC/ACR (r = −0.377, p = 0.038. Multiple regression analysis identified hair Hg as a significant predictor of disease associated damage as determined by SLICC/ACR (β = −0.366, 95% confidence interval (CI: −1.769, −0.155 p = 0.019. Urinary Hg was not related to disease activity or damage. Fish consumption is the primary route of MeHg exposure in humans and the inverse association of hair Hg with disease activity observed here might be explained by the anti-inflammatory effects of n-3 long chain polyunsaturated fatty acids also found in fish.

    American Muslims have low rates of mammography utilization, and research suggests that religious values influence their health-seeking behaviors. We assessed associations between religion-related factors and breast cancer screening in this population. A diverse group of Muslim women were recruited from mosques and Muslim organization sites in Greater Chicago to self-administer a survey incorporating measures of fatalism, religiosity, discrimination, and Islamic modesty. 254 surveys were collected of which 240 met age inclusion criteria (40 years of age or older). Of the 240, 72 respondents were Arab, 71 South Asian, 59 African American, and 38 identified with another ethnicity. 77 % of respondents had at least one mammogram in their lifetime, yet 37 % had not obtained mammography within the past 2 years. In multivariate models, positive religious coping, and perceived religious discrimination in healthcare were negatively associated with having a mammogram in the past 2 years, while having a PCP was positively associated. Ever having a mammogram was positively associated with increasing age and years of US residency, and knowing someone with breast cancer. Promoting biennial mammography among American Muslims may require addressing ideas about religious coping and combating perceived religious discrimination through tailored interventions.

    Full Text Available We introduced a hypometabolic convergence index (HCI to characterize in a single measurement the extent to which a person's fluorodeoxyglucose positron emission tomogram (FDG PET corresponds to that in Alzheimer's disease (AD. Apolipoprotein E ε4 (APOE ε4 gene dose is associated with three levels of risk for late-onset AD. We explored the association between gene dose and HCI in cognitively normal ε4 homozygotes, heterozygotes, and non-carriers.An algorithm was used to characterize and compare AD-related HCIs in cognitively normal individuals, including 36 ε4 homozygotes, 46 heterozygotes, and 78 non-carriers.These three groups differed significantly in their HCIs (ANOVA, p = 0.004, and there was a significant association between HCIs and gene dose (linear trend, p = 0.001.The HCI is associated with three levels of genetic risk for late-onset AD. This supports the possibility of using a single FDG PET measurement to help in the preclinical detection and tracking of AD.

    Comorbidities are common in multiple sclerosis (MS). The high prevalence of pain in MS is well-established but the influence of comorbidities on pain, specifically, pain-related interference in activity is not. To examine the relationship between comorbidity and pain in MS. We recruited 949 consecutive patients with definite MS from four Canadian centres. Participants completed the Health Utilities Index (HUI-Mark III) and a validated comorbidity questionnaire at 3 visits over 2 years. The HUI's pain scale was dichotomized into two groups: those with/without pain that disrupts normal activities. We used logistic regression to assess the association of pain with each comorbidity individually at baseline and over time. The incidence of disruptive pain over two years was 31.1 per 100 persons. Fibromyalgia, rheumatoid arthritis, irritable bowel syndrome, migraine, chronic lung disease, depression, anxiety, hypertension, and hypercholesterolemia were associated with disruptive pain (ppain were seen for chronic obstructive pulmonary disease (odds ratio [OR]: 1.50 95% CI: 1.08-2.09), anxiety (OR: 1.49 95% CI: 1.07-2.08), and autoimmune thyroid disease (OR: 1.40 95% CI: 1.00-1.97). Comorbidity is associated with pain in persons with MS. Closer examination of these associations may provide guidance for better management of this disabling symptom in MS.

    This study aimed to identify variables associated with quality of life (QoL) and mediating variables among 338 service users with mental disorders in Quebec (Canada). Data were collected using nine standardized questionnaires and participant medical records. Quality of life was assessed with the Satisfaction with Life Domains Scale. Independent variables were organized into a six-block conceptual framework. Using structural equation modeling, associated and mediating variables related to QoL were identified. Lower seriousness of needs was the strongest variable associated with QoL, followed by recovery, greater service continuity, gender (male), adequacy of help received, not living alone, absence of substance use or mood disorders, and higher functional status, in that order. Recovery was the single mediating variable linking lower seriousness of needs, higher service continuity, and reduced alcohol use with QoL. Findings suggest that greater service continuity creates favorable conditions for recovery, reducing seriousness of needs and increasing QoL among service users. Lack of recovery-oriented services may affect QoL among alcohol users, as substance use disorders were associated directly and negatively with QoL. Decision makers and mental health professionals should promote service continuity, and closer collaboration between primary care and specialized services, while supporting recovery-oriented services that encourage service user involvement in their treatment and follow-up. Community-based organizations should aim to reduce the seriousness of needs particularly for female service users and those living alone.

    Differences in DNA methylation have been associated with early life adversity, suggesting that alterations in methylation function as one pathway through which adverse early environments are biologically embedded. This study examined associations between exposure to institutional care, quantified as the proportion of time in institutional care at specified follow-up assessment ages, and DNA methylation status in two stress-related genes: FKBP5 and SLC6A4. We analyzed data from the Bucharest Early Intervention Project, which is a prospective study in which children reared in institutional settings were randomly assigned (mean age 22 months) to either newly created foster care or care as usual (to remain in their current placement) and prospectively followed. A group of children from the same geographic area, with no history of institutionalized caregiving, were also recruited. DNA methylation status was determined in DNA extracted from buccal epithelial cells of children at age 12. An inverse association was identified such that more time spent in institutional care was associated with lower DNA methylation at specific CpG sites within both genes. These results suggest a lasting impact of early severe social deprivation on methylation patterns in these genes, and contribute to a growing literature linking early adversity and epigenetic variation in children.

    Information technologies have been developing very rapidly, also in the case of occupational activities. Epidemiological studies have shown that employees, who work with computers, are more likely to complain of musculoskeletal disorders (MSD). The aim of this study was to evaluate associations between neck MSD and individual and work related factors. The investigation which consisted of two parts - a questionnaire study (using Nordic Musculoskeletal questionnaire and Copenhagen Psychosocial Questionnaire) and a direct observation (to evaluate ergonomic work environment using RULA method) was carried out in three randomly selected public sector companies of Kaunas. The study population consisted of 513 public service office workers. The survey showed that neck MSDs were very common in the investigated population. The prevalence rate amounted to 65.7%. According to our survey neck MSDs were significantly associated with older age, bigger work experience, high quantitative and cognitive job demands, working for longer than 2 h without taking a break as well as with higher ergonomic risk score. The fully adjusted model working for longer than 2 h without taking a break had the strongest associations with neck complaints. It was confirmed, that neck MSDs were significantly associated with individual factors as well as conditions of work, therefore, preventive actions against neck complaints should be oriented at psychosocial and ergonomic work environment as well as at individual factors.

    Over the past 40 years, the prevalence of obesity has increased epidemically worldwide, which raises significant concerns regarding public health and the associated economic burden. Obesity is a major risk factor for several conditions including cardiovascular disease and type 2 diabetes, and recent evidence suggests that obesity negatively affects cancer risk and outcome. The relationship between obesity and cancer is complex and involves multiple factors both at the systemic and cellular level. Indeed, disruptions in insulin metabolism, adipokines, inflammation, and sex hormones all contribute to the adverse effects of obesity in cancer development and progression. The focus of this review will be the impact of these systemic obesity-related factors on cancer biology, incidence, and outcome. Potential therapeutic interventions and current clinical trials targeting obesity and its associated factors will also be discussed.

    This study aimed to estimate the incidence of non-fatal work-related accidents in the informal commercial sector and analyze associated socio-demographic, occupational, workplace, and health factors, in a cross-sectional survey of 434 workers in the business district of Jequié, Bahia State, Brazil, in 2013. Logistic regression was used to assess factors associated with accidents. Incidence of accidents in the previous 12 months was estimated at 32.3%, and multivariate analysis showed higher odds of accidents in male sex workers (OR = 1.61), young individuals (OR = 4.62), meat or poultry workers (OR = 9.55), and workers performing heavy physical work (OR = 1.71). The results show the need for public policies to prevent accidents in the informal commercial sector.

    Full Text Available The quaternion Wigner-Ville distribution associated with linear canonical transform (QWVD-LCT is a nontrivial generalization of the quaternion Wigner-Ville distribution to the linear canonical transform (LCT domain. In the present paper, we establish a fundamental relationship between the QWVD-LCT and the quaternion Fourier transform (QFT. Based on this fact, we provide alternative proof of the well-known properties of the QWVD-LCT such as inversion formula and Moyal formula. We also discuss in detail the relationship among the QWVD-LCT and other generalized transforms. Finally, based on the basic relation between the quaternion ambiguity function associated with the linear canonical transform (QAF-LCT and the QFT, we present some important properties of the QAF-LCT.

    Is a genetic risk score (GRS) associated with polycystic ovary syndrome (PCOS) and its related clinical features? The GRS calculated by genome-wide association studies (GWASs) was significantly associated with PCOS status and its related clinical features. PCOS is a heterogeneous disorder and is characterized by oligomenorrhea, hyperandrogenism and polycystic ovary morphology. Although recent GWASs have identified multiple genes associated with PCOS, a comprehensive genetic risk study of these loci with PCOS and related traits (e.g. free testosterone, menstruation number/year and ovarian morphology) has not been performed. This study was designed as a cross-sectional case-control study. We recruited 862 women with PCOS and 860 controls. Women with PCOS were divided into four subgroups: (1) oligomenorrhea + hyperandrogenism + polycystic ovary, (2) oligomenorrhea + hyperandrogenism, (3) oligomenorrhea + polycystic ovary and (4) hyperandrogenism + polycystic ovary. Genomic DNA was genotyped for the PCOS susceptibility loci using the HumanOmni1-Quad v1 array. Venous blood was drawn in the early follicular phase to measure baseline metabolic and hormonal parameters. A GRS was calculated by summing the number of risk alleles from 11 single-nucleotide polymorphisms (SNPs) that were identified in previous GWASs on PCOS. A weighted GRS (wGRS) was calculated by multiplying the number of risk alleles for each SNP by its estimated effect (beta) obtained from the association analysis. The GRS was higher in women with PCOS than in controls (8.8 versus 8.2, P < 0.01) and was significantly associated with PCOS after adjusting for age and BMI. An analysis of GRS quartiles (Q1 = 3-5, Q2 = 6-8, Q3 = 9-11, Q4 = 12-15) revealed that the subjects in the highest quartile showed a remarkable increased risk of PCOS compared with those in the lowest quartile (odds ratio = 6.28, P < 0.001).

    This study examined the associations between indicators of health-related physical fitness (cardiovascular fitness and body mass index) and academic performance (Texas Assessment of Knowledge and Skills). Partial correlations were generally stronger for cardiovascular fitness than body mass index and consistently stronger in the middle school grades. Mixed-model regression analyses revealed modest associations between fitness and academic achievement after controlling for potentially confounding variables. The effects of fitness on academic achievement were positive but small. A separate logistic regression analysis indicated that higher fitness rates increased the odds of schools achieving exemplary/recognized school status within the state. School fitness attainment is an indicator of higher performing schools. Direction of causality cannot be inferred due to the cross-sectional nature of the data.

    This study was conducted to investigate the associations among work-related musculoskeletal disorders (WMSDs), job stress, and job attitude of occupational therapists in South Korea. Self-reporting questionnaires were distributed to 150 occupational therapists. Of the 128 occupational therapists who responded, 110 (85.9%) reported WMSDs affecting at least one body site. The most affected WMSDs site was the low back (26.8%), and the most reported number of body site affected by WMSDs was one (53.9%). As a result, there were significant differences in job stress and job attitude depending on the age, work experience, working hour, presence or absence of WMSDs, and number of site of pain. Factors influencing job attitude included job stress, the presence or absence of WMSDs and duration of pain. The results showed that the occurrence of WMSDs in occupational therapists was associated with increased job stress and negative job attitude.

    Despite growing trends in adolescent female aggression, much adolescent aggression research has focused on males to the exclusion of their female counterparts. Using relational-cultural and social role theories, the current study identifies the risk and promotive factors associated with adolescent female aggression. Using data from the Rural Adaptation Project (a 5 year longitudinal panel study of youth from two rural, ethnically diverse, low income counties in North Carolina), a 2-level hierarchical linear model was estimated (N = 3580). Internalizing symptoms, association with delinquent friends, peer pressure, and parent-child conflict emerged as risk factors whereas teacher support was a significant promotive factor. Results suggest that interventions should focus on negative relationships in both the parent and peer domains and underscore the need for mental health services for aggressive girls.

    Age-related changes of the dopamine nerve fibres of bronchus associated lymphoid tissue (BALT) were investigated in male Wistar rats of 3 months (young), and 24 months (old/aged). Dopamine histofluorescence techniques have been used, associated with image analysis for the detection of dopamine nerve fibres. In young rats, white, fluorescent nerve fibres supply BALT. This tissue is innervated by a delicate network of nerve fibres rich in varicosities. In old rats these fluorescent nerve fibres are strongly reduced. Moreover, dopamine D1a and D1b receptors were stained using fluorescent monoclonal antibodies. The BALT of young rats possesses a higher number of D1a and D1b receptors, while, in the old rats, these receptors are strongly reduced. The possible significance of reduced dopamine neurotransmission in BALT of aged rats is discussed.

    Circadian disruptions can contribute to accelerated aging, and the circadian system regulates cognitive and physical functions; therefore, circadian markers (eg, melatonin) may be associated with key aspects of healthy aging and longevity. To evaluate urinary melatonin levels in relation to cognitive function, physical function, and mortality among 2,821 older men in the Osteoporotic Fractures in Men Study DESIGN: Cohort study. In 2003-2005, participants provided first-morning spot urine samples, which were assayed for 6-sulfatoxymelatonin (the primary melatonin metabolite in urine); cognitive and physical function assessments were completed twice, at baseline and an average of 6.5 years later. Participant deaths were confirmed by central review of death certificates over a mean of 9.2 years of follow up. In multivariable-adjusted regression models, we observed a significant trend of better Digit Vigilance Test scores (ie, decreased time to completion) at baseline across increasing melatonin quartiles (p-trend = 0.01); however, mean time-to-completion scores did not significantly differ comparing extreme quartiles (group means: 547.1 seconds (95% CI: 533.6, 560.6) versus 561.3 seconds (95% CI: 547.8, 574.9)), and there were no associations of urinary melatonin levels with other cognitive test scores, or any cognitive change scores over time. Furthermore, melatonin levels were not related to physical function scores (p-trends = 0.4 for walking speed, 0.7 for chair stands, and 0.6 for grip strength in fully-adjusted models) or mortality risk (p-trend = 0.3 in the fully-adjusted model). We found little evidence of associations between urinary melatonin levels and key measures of healthy aging and mortality in this cohort of older men. Further research should explore the relation of melatonin, particularly if assessed earlier in life, and other circadian markers with healthy aging outcomes. Copyright © 2016 Elsevier B.V.

    The existing body of evidence reports an inconsistent association between subjective and objective orthodontic treatment need. The concept of oral health-related quality of life (OHRQoL) might help to explain the differences in subjective and objective orthodontic treatment need. Our aim was to investigate the association of subjective orthodontic treatment with OHRQoL in children. This cross-sectional study was embedded in the Generation R Study, a population-based prospective cohort study. OHRQoL and subjective orthodontic treatment need were assessed by parental questionnaires. Questionnaire items were individually compared among children with no, borderline and definite subjective orthodontic need. The association between subjective orthodontic treatment need and OHRQoL was investigated in multivariate regression analysis with weighted least squares. Differences by sex and levels of objective orthodontic treatment need were evaluated. In total, 3774 children were included in the analysis. Children with borderline subjective orthodontic treatment need and those with definite subjective orthodontic treatment need had significantly poorer OHRQoL based on the fully adjusted model (adjusted regression coefficient (aβ)=-0.49, 95% CI: -0.75, -0.30; (aβ)=-1.58, 95% CI: -1.81, -1.58, respectively). The association between subjective orthodontic treatment need and OHRQoL was stronger in girls than in boys and stronger in children with objective orthodontic treatment need than in those with none. Oral health-related quality of life is poorer in children with subjective orthodontic treatment need. This has not been investigated before in such a large-population-based study and clearly offers an explanation for the lack of concurrence between objective and subjective orthodontic treatment need. © 2017 John Wiley & Sons A/S.

    Firearms account for a substantial proportion of external causes of death, injury, and disability across the world. Legislation to regulate firearms has often been passed with the intent of reducing problems related to their use. However, lack of clarity around which interventions are effective remains a major challenge for policy development. Aiming to meet this challenge, we systematically reviewed studies exploring the associations between firearm-related laws and firearm homicides, suicides, and unintentional injuries/deaths. We restricted our search to studies published from 1950 to 2014. Evidence from 130 studies in 10 countries suggests that in certain nations the simultaneous implementation of laws targeting multiple firearms restrictions is associated with reductions in firearm deaths. Laws restricting the purchase of (e.g., background checks) and access to (e.g., safer storage) firearms are also associated with lower rates of intimate partner homicides and firearm unintentional deaths in children, respectively. Limitations of studies include challenges inherent to their ecological design, their execution, and the lack of robustness of findings to model specifications. High quality research on the association between the implementation or repeal of firearm legislation (rather than the evaluation of existing laws) and firearm injuries would lead to a better understanding of what interventions are likely to work given local contexts. This information is key to move this field forward and for the development of effective policies that may counteract the burden that firearm injuries pose on populations. © The Author 2016.

    To examine burnout prevalence among California neonatal intensive care units (NICUs) and to test the relation between burnout and healthcare-associated infection (HAI) rates in very low birth weight (VLBW) neonates. Retrospective observational study of provider perceptions of burnout from 2073 nurse practitioners, physicians, registered nurses and respiratory therapists, using a validated four-item questionnaire based on the Maslach Burnout Inventory. The relation between burnout and HAI rates among VLBW (burnout across the NICUs surveyed (mean 25.2±10.1%). Healthcare-associated infection rates were 8.3±5.1% during the study period. Highest burnout prevalence was found among nurses, nurse practitioners and respiratory therapists (non-physicians, 28±11% vs 17±19% physicians), day shift workers (30±3% vs 25±4% night shift) and workers with 5 or more years of service (29±2% vs 16±6% in fewer than 3 years group). Overall burnout rates showed no correlation with risk-adjusted rates of HAIs (r=-0.133). Item-level analysis showed positive association between HAIs and perceptions of working too hard (odds ratio 1.15, 95% confidence interval 1.04-1.28). Sensitivity analysis of high-volume NICUs suggested a moderate correlation between burnout prevalence and HAIs (r=0.34). Burnout is most prevalent among non-physicians, daytime workers and experienced workers. Perceptions of working too hard associate with increased HAIs in this cohort of VLBW infants, but overall burnout prevalence is not predictive.

    Abstract Background: Recently, several studies showed that the polymorphisms in the coagulation-related genes might be associated with venous thromboembolism (VTE); however, the results were still controversial. We performed a meta-analysis with trial sequential analysis to investigate the associations between the endothelial cell-activated protein C receptor (EPCR) rs9574, F11 rs2289252, F11 rs2036914, FGG rs2066865, FGG rs1049636, CYP4V2 rs13146272, SERPINC1 rs2227589, and GP6 rs1613662 polymorphisms with the risk of VTE. Methods: We searched both the common English-language databases and the Chinese literature databases. Two authors selected studies according to inclusion and exclusion criteria. Crude odds ratios with 95% confidence intervals (CI) were calculated to estimate the strength of this association. Between-study heterogeneity was assessed with the chi-square-based Q test and the I2 statistic. Results: Overall, a total of 20 studies were included. The meta-analysis revealed that the F11 rs2289252, F11 rs2036914, FGG rs2066865, and CYP4V2 rs13146272 polymorphisms were closely related to the development of VTE in the white race under the best genetic models after multiple testing adjustments. The EPCR rs9574, FGG rs1049636, SERPINC1 rs2227589, and GP6 rs1613662 polymorphisms might be potential candidates in the pathogenesis of VTE, but trial sequential analyses and sensitivity analyses indicated that the evidences were limited. Larger scale studies were demanded to avoid false-positive outcomes. Conclusions: Finally, our study demonstrated the important role of rs2289252, rs2036914, rs2066865, and rs13146272 polymorphisms in the development of VTE in the white race. Rs9574, rs1049636, rs2227589 and rs1613662 polymorphisms might be risk factors of VTE. However, more studies involving diverse races are needed to probe the ethnic difference and the underlying mechanisms of significant associations. PMID:28353616

    Our study examined the relationships of relational pronouns used in parental conversation to the quality of early family interactions, as indexed by Family Alliance (FA). We hypothesized that more positive family interactions were associated with the use of more we-pronouns (e.g., we, us, our; we-ness) and fewer I- and you-pronouns (e.g., I, me, you, your; separateness) by both mothers and fathers. Our statistical model using a multilevel modeling framework and two levels of analysis (i.e., a...

    Some markers of chronic inflammation have been recognized as predictors of cardiovascular risk in apparently healthy subjects and in patients with coronary heart disease (CHD). High sensitivity C-reactive protein (CRP) appears to be the most useful marker in clinical settings. Several studies reported associations between inflammatory markers and other cardiovascular risk factors, such as age, obesity, cholesterol levels, the presence of diabetes mellitus, physical activity, social level and smoking habits. We focussed on the association between C-reactive protein, serum amyloid A (SAA), fibrinogen and leisure time physical activity (LTPA). This report deals with the results observed in a sub-sample of the BELSTRESS study. 892 male subjects, free from clinical CHD and major ECG abnormalities, working in the same environment, aged 35-59 years, were selected. A questionnaire was used to estimate the level of leisure time physical activity. Associations between CRP, SAA, fibrinogen and leisure time physical activity were evaluated through univariate and multivariate methods. Subjects taking statins or other lipid lowering medication were excluded from the study. Regular leisure time physical activity is associated with reductions of several cardiovascular risk factors, such as body mass index (BMI), waist hip ratio and the lipid profile. Smokers and low educated subjects had a lower physical activity status. Age adjustment did not alter the means of inflammatory parameters according to the levels of leisure time physical activity. After correction for personal characteristics (BMI, current smoking status, educational level, presence of diabetes and alcohol consumption) no significant relation was found between leisure time physical activity and levels of inflammatory markers. The differences of CRP and fibrinogen according to the level of physical activity, found in bivariate analysis, seem to be explained by linked differences in BMI, or related to current smoking

    Previous findings on the relationship between suicide ideation (SI) and alcohol misuse among college students are inconsistent, leading to conflicting clinical implications. We aimed to clarify this relationship in order to determine the utility of regarding alcohol misuse as a risk factor for SI in this population. Unselected college students (N = 545) completed an online survey including measures of alcohol consumption, problems, drinking motives, SI, and related variables. Our results suggest alcohol misuse is not a correlate of SI among college students; therefore, one should not assume that students who misuse alcohol are necessarily at increased risk for SI. © 2016 The American Association of Suicidology.

    We report on the potential application of Raman spectroscopy for the fast typing of Staphylococcus epidermidis (S. epidermidis) strains related to medical device-associated infections. In this study bacterial colonies were directly probed on culture plates and Raman spectra were recorded from volumes containing approximately 10 bacteria. The spectra contain information on the molecular composition of the whole bacteria, such as fatty acids, carbohydrates, proteins and nucleic acids, DNA as well as RNA. We demonstrate the potential to discriminate different S. epidermidis clones, even after only short Raman exposure/collection times.

    2017-02-01

    High attrition in associate degree nursing (ADN) programs contributes to the nursing shortage and causes hardship for students, families, faculty, colleges, and taxpayers. The purpose of this integrative literature review is to identify admission criteria related to ADN program success to inform evidence-based admission policies and reduce attrition. Integrative review methodology, suggested by Whittemore and Knafl, was used. A systematic search of existing professional literature was conducted using five databases and key word searches. The final sample included 26 documents that were analyzed and synthesized with the matrix method. Five categories of admission criteria and factors related to success in ADN programs were revealed from the analysis of findings: academic aptitude, demographic factors, psychological hardiness, specialty skills and experience, and socioeconomic support. ADN programs with a goal of decreasing attrition may want to implement admission selection guidelines that consider applicant criteria and attributes across all five dimensions.

    Full Text Available Osteonecrosis of the jaw (ONJ is a serious complication associated with oral and intravenous bisphosphonate therapy. Its pathogenesis is not well understood and its management is difficult. Microbiological investigations have detected a variety of oral pathogens such as Actinomyces, Enterococcus, Candida albicans, Aspergillus, Haemophilus influenzae, alpha-hemolytic streptococci, Lactobacillus, Enterobacter, and Klebsiella pneumoniae. To better treat it, it is important to understand its causes and complications. Materials and Methods. Our present study addresses a microscopic observation of curetted jaw necrotic lesions related to bisphosphonates. Results. A mycotic infestation has been found in all of the 18 cases studied. Discussion. An identification of the fungal agent and its incrimination in the pathogenesis of bisphosphonates related osteonecrosis of the jaw could change radically the management of this condition.

    Antiretroviral therapy has led to a decrease in HIV-related mortality and to the emergence of non-AIDS defining diseases as competing causes of death. This study estimates the HIV mortality rate and their risk factors with regard to different causes in a large city from January 2001 to June 2013. We followed-up 3137 newly diagnosed HIV non-AIDS cases. Causes of death were classified as HIV-related, non-HIV-related and external. We examined the effect of risk factors on survival using mortality rates, Kaplan-Meier plots and Cox models. Finally, we estimated survival for each main cause of death groups through Fine and Gray models. 182 deaths were found [14.0/1000 person-years of follow-up (py); 95% confidence interval (CI):12.0-16.1/1000 py], 81.3% of them had a known cause of death. Mortality rate by HIV-related causes and non-HIV-related causes was the same (4.9/1000 py; CI:3.7-6.1/1000 py), external was lower [1.7/1000 py; (1.0-2.4/1000 py)]. Kaplan-Meier estimate showed worse survival in intravenous drug user (IDU) and heterosexuals than in men having sex with men (MSM). Factors associated with HIV-related causes of death include: IDU male (subHazard Ratio (sHR):3.2; CI:1.5-7.0) and HIV-related causes of death include: ageing (sHR:1.5; CI:1.4-1.7) and heterosexual female (sHR:2.8; CI:1.1-7.3) versus MSM. Factors associated with external causes of death were IDU male (sHR:28.7; CI:6.7-123.2) and heterosexual male (sHR:11.8; CI:2.5-56.4) versus MSM. There are important differences in survival among transmission groups. Improved treatment is especially necessary in IDUs and heterosexual males.

  13. Wnt16 Is Associated with Age-Related Bone Loss and Estrogen Withdrawal in Murine Bone.

    Directory of Open Access Journals (Sweden)

    Henry Todd

    Full Text Available Genome Wide Association Studies suggest that Wnt16 is an important contributor to the mechanisms controlling bone mineral density, cortical thickness, bone strength and ultimately fracture risk. Wnt16 acts on osteoblasts and osteoclasts and, in cortical bone, is predominantly derived from osteoblasts. This led us to hypothesize that low bone mass would be associated with low levels of Wnt16 expression and that Wnt16 expression would be increased by anabolic factors, including mechanical loading. We therefore investigated Wnt16 expression in the context of ageing, mechanical loading and unloading, estrogen deficiency and replacement, and estrogen receptor α (ERα depletion. Quantitative real time PCR showed that Wnt16 mRNA expression was lower in cortical bone and marrow of aged compared to young female mice. Neither increased nor decreased (by disuse mechanical loading altered Wnt16 expression in young female mice, although Wnt16 expression was decreased following ovariectomy. Both 17β-estradiol and the Selective Estrogen Receptor Modulator Tamoxifen increased Wnt16 expression relative to ovariectomy. Wnt16 and ERβ expression were increased in female ERα-/- mice when compared to Wild Type. We also addressed potential effects of gender on Wnt16 expression and while the expression was lower in the cortical bone of aged males as in females, it was higher in male bone marrow of aged mice compared to young. In the kidney, which we used as a non-bone reference tissue, Wnt16 expression was unaffected by age in either males or females. In summary, age, and its associated bone loss, is associated with low levels of Wnt16 expression whereas bone loss associated with disuse has no effect on Wnt16 expression. In the artificially loaded mouse tibia we observed no loading-related up-regulation of Wnt16 expression but provide evidence that its expression is influenced by estrogen receptor signaling. These findings suggest that while Wnt16 is not an

    Full Text Available Abstract Background Stress, elicited for example by aggressive interactions, has negative effects on various biological functions including immune defence, reproduction, growth, and, in livestock, on product quality. Stress response and aggressiveness are mutually interrelated and show large interindividual variation, partly attributable to genetic factors. In the pig little is known about the molecular-genetic background of the variation in stress responsiveness and aggressiveness. To identify candidate genes we analyzed association of DNA markers in each of ten genes (CRH g.233C>T, CRHR1 c.*866_867insA, CRHBP c.51G>A, POMC c.293_298del, MC2R c.306T>G, NR3C1 c.*2122A>G, AVP c.207A>G, AVPR1B c.1084A>G, UCN g.1329T>C, CRHR2 c.*13T>C related to the hypothalamic-pituitary-adrenocortical (HPA axis, one of the main stress-response systems, with various stress- and aggression-related parameters at slaughter. These parameters were: physiological measures of the stress response (plasma concentrations of cortisol, creatine kinase, glucose, and lactate, adrenal weight (which is a parameter reflecting activity of the central branch of the HPA axis over time and aggressive behaviour (measured by means of lesion scoring in the context of psychosocial stress of mixing individuals with different aggressive temperament. Results The SNP NR3C1 c.*2122A>G showed association with cortisol concentration (p = 0.024, adrenal weight (p = 0.003 and aggressive behaviour (front lesion score, p = 0.012; total lesion score p = 0.045. The SNP AVPR1B c.1084A>G showed a highly significant association with aggressive behaviour (middle lesion score, p = 0.007; total lesion score p = 0.003. The SNP UCN g.1329T>C showed association with adrenal weight (p = 0.019 and aggressive behaviour (front lesion score, p = 0.029.

    2013-01-01

    TP53’s role as guardian of the genome diminishes with age, as the probability of mutation increases. Previous studies have shown an association between p53 gene mutations and cancer. However, the role of somatic TP53 mutations in the steep rise in cancer rates with aging has not been investigated at a population level. This relationship was quantified using the International Agency for Research on Cancer (IARC) TP53 and GLOBOCAN cancer databases. The power function exponent of the cancer rate was calculated for 5-y age-standardized incidence or mortality rates for up to 25 cancer sites occurring in adults of median age 42 to 72 y. Linear regression analysis of the mean percentage of a cancer’s TP53 mutations and the corresponding cancer exponent was conducted for four populations: worldwide, Japan, Western Europe, and the United States. Significant associations (P ≤ 0.05) were found for incidence rates but not mortality rates. Regardless of the population studied, positive associations were found for all cancer sites, with more significant associations for solid tumors, excluding the outlier prostate cancer or sex-related tumors. Worldwide and Japanese populations yielded P values as low as 0.002 and 0.005, respectively. For the United States, a significant association was apparent only when analysis utilized the Surveillance, Epidemiology, and End Results (SEER) database. This study found that TP53 mutations accounts for approximately one-quarter and one-third of the aging-related rise in the worldwide and Japanese incidence of all cancers, respectively. These significant associations between TP53 mutations and the rapid rise in cancer incidence with aging, considered with previously published literature, support a causal role for TP53 according to the Bradford-Hill criteria. However, questions remain concerning the contribution of TP53 mutations to neoplastic development and the role of factors such as genetic instability, obesity, and gene deficiencies

    Evidence is accumulating supporting gender-related differences in the development of colonic carcinomas. Sex steroid hormone receptors are expressed in the colon and interact with epidermal growth factor receptor (EGFR), a gene widely expressed in colonic tissue. Increased EGFR expression is linked with poor prognosis in colon cancer. Within the EGFR gene there are two functional polymorphisms of interest: a polymorphism located at codon 497 (HER-1 R497K) and a dinucleotide (CA)(n) repeat polymorphism located within intron 1. These germ-line polymorphisms of EGFR were analyzed in genomic DNA from 318 metastatic colon cancer patients, 177 males and 141 females, collected from 1992 to 2003. Gender-related survival differences were associated with the HER-1 R497K polymorphism (P(interaction) = 0.003). Females with the HER-1 497 Arg/Arg variant had better overall survival (OS) when compared with the Lys/Lys and/or Lys/Arg variants. In males the opposite was true. The EGFR dinucleotide (CA)(n) repeat also trended with a gender-related OS difference (P(interaction) = 0.11). Females with both short or=20 (CA)(n) repeats. In males the opposite was true. Combination analysis of the two polymorphisms taken together also revealed the same gender-related survival difference (P(interaction) = 0.002). These associations were observed using multivariable analysis. The two polymorphisms were not in linkage disequilibrium and are independent of one another. This study supports the role of functional EGFR polymorphisms as independent prognostic markers in metastatic colon cancer. As a prognostic factor, these variants had opposite prognostic implications based on gender.

    Adipose tissue autophagy (AT) is associated with human obesity and increased metabolic risk. Recent findings establish a role for autophagy in lipid metabolism. Here, we compared the expression of autophagy-related and lipolysis genes in human abdominal subcutaneous AT (SCAT) in overweight/obese subjects (n = 17) with or without impaired glucose tolerance in comparison with lean normal glucose tolerant individuals (n = 9), and investigated the association between AT autophagy and lipolysis. Human multipotent adipose-derived stem cells (hMADS) were used to investigate the effect of pharmacological HSL inhibition on changes in the autophagic flux. The expression of autophagy-related genes (ATG) 5, 7 and 12 in SCAT was significantly higher (p = 0.043, p = 0.015, p = 0.004, respectively) in overweight/obese compared to lean men, while expression of the classical lipases HSL (p = 0.092) and ATGL (p = 0.084) tended to be lower. ATG12 mRNA was positively correlated with BMI (r = 0.407, p = 0.039). ATG7 mRNA correlated positively with waist/hip ratio (WHR) (r = 0.420, p = 0.041), 2 h glucose concentration (r = 0.488, p = 0.011) and insulin (r = 0.419, p = 0.033). Multiple linear regressions revealed that ATG7 gene expression was positively related to 2 h glucose, independent of BMI, WHR and insulin. Gene expression interaction analysis showed that ATG7 mRNA negatively correlated with HSL (p<0.01) and ATGL mRNA expression (p<0.01). In line, treatment of differentiated hMADS with an HSL inhibitor increased LC3 accumulation, a marker of increased autophagic flux. Collectively, the present study demonstrated that a low expression of classical lipases in abdominal SCAT is accompanied by an increased expression of ATGs in overweight/obese subjects, which seems to be mainly related to glucose tolerance.

    Background Stress-related eating is associated with unhealthy eating and drinking habits and an increased risk of obesity among adults, but less is known about factors related to stress-driven eating behaviour among children and adolescents. We studied the prevalence of stress-related eating and its association with overweight, obesity, abdominal obesity, dietary and other health behaviours at the age of 16. Furthermore, we examined whether stress-related eating is predicted by early-life fac...

    The purpose of this study is to investigate how family-related opinions and stressful situations are related to psychological distress in women undergoing infertility treatment. The subjects in this cross-sectional study were recruited from female patients undergoing infertility treatment (n = 2540) at 70 infertility treatment institutions in Japan. Because of non-participation or missing data, the number of subjects included in the analysis was 635 (response rate, 25.0%). The family-related opinions and stressful situations were evaluated using the original questions. Psychological distress was assessed using a self-report measure, the Kessler Six-question Psychological Distress Scale (K6). The K6 scores of the following participants were significantly (p infertility, those with infertility of unknown causes, those living with no child, those having a low joint income with their partner, those with the opinion that "women should devote themselves to their household duties" those who had considered stopping treatment, those without the opinion that "married life without children is favorable" and those who had experienced stressful situations such as inadequate explanation by doctors, frustration of multiple failed attempts, differences of opinion with the partner, and lack of knowledge regarding when to stop treatment. Family-related opinions and stressful situations associated with psychological distress in women undergoing infertility treatment are outlined. The results of this study may contribute to the prevention of and care for psychological distress in female patients undergoing infertility treatment.

    Full Text Available The aim of this paper is to contribute to the debate on population aging and growth in health expenditures, by providing precise estimates on how mortality related expenditures are influenced by age. Using a complete register of inpatient hospital admissions to create gender-cohort specific panels for each of the 430 Norwegian municipalities, we are able to identify mortality related hospital expenditures by separating the impact of mortality on current hospital expenditures from the impact of patients’ age and gender. We apply model estimates to quantify the mortality-related hospital expenditures for twenty age groups. The results suggest that mortality-related hospital expenditures are a decreasing function of age. Furthermore, the results clearly suggest that, both age and mortalities should be included when predicting future health care expenditures. The estimation results suggest that 9.2 % of all hospital expenditures is associated with treating individuals in their last year of life. Our results also suggest that the reduction in mortality rates in the period from 1998 to 2009 have, cet. par. contributed to an estimated reduction in total hospital expenditures of 0.6 billion NOK, a difference corresponding to 2 % of the expenditures in 2009. (The appendix can be found under "Supplementary Files" in the menu to the right

    The current study sought to investigate the association between HIV-related stigma, self-esteem, social support, and depression of people living with HIV and AIDS (PLWHA) in Namibia. Purposive sampling was used to recruit a total of 124 men and women living with HIV/AIDS in the Katima Mulilo region of northern Namibia. A cross-sectional survey was used to collect information on demographics, self-esteem, social support, HIV-related stigma, and depression. Correlation analysis revealed that HIV-related stigma, self-esteem, and social support were all significantly correlated with depression. Further, Ordinary Least Squares (OLS) regression analysis indicated that HIV-related stigma was the largest risk factor and self-esteem was the largest protective factor with respect to depressive symptoms. Findings indicated the necessity of appropriate assessment and intervention for psychosocial distress among PLWHA. Helping professionals should design evidence-based interventions that address individual and societal challenges that impact people living with HIV and AIDS.

    The purpose of this study was to use a cross-sectional prevalence-based health care economic survey to ascertain the annual, incremental, societal ophthalmic costs associated with neovascular age-related macular degeneration. Consecutive patients (n = 200) with neovascular age-related macular degeneration were studied. A Control Cohort included patients with good (20/20-20/25) vision, while Study Cohort vision levels included Subcohort 1: 20/30 to 20/50, Subcohort 2: 20/60 to 20/100, Subcohort 3: 20/200 to 20/400, and Subcohort 4: 20/800 to no light perception. An interviewer-administered, standardized, written survey assessed 1) direct ophthalmic medical, 2) direct nonophthalmic medical, 3) direct nonmedical, and 4) indirect medical costs accrued due solely to neovascular age-related macular degeneration. The mean annual societal cost for the Control Cohort was $6,116 and for the Study Cohort averaged $39,910 (P age-related macular degeneration dramatically increase as vision in the better-seeing eye decreases.

    To report the association of pure type 2 neovascularization (NV) in age-related macular degeneration occurring almost exclusively in patients with reticular pseudodrusen. An observational retrospective cohort study of all eyes receiving antivascular endothelial growth factor therapy for newly diagnosed neovascular age-related macular degeneration by a single practitioner over a 6-year period. Only patients with treatment-naive, pure type 2 NV who also had either pre-neovascular imaging of the study eye or imaging of a nonneovascular fellow eye available to determine baseline characteristics including drusen type and choroidal thickness were incuded. Of 694 patients treated for neovascular age-related macular degeneration, only 8 met the inclusion criteria with pure type 2 NV. Of these, 7 (88%) had exclusively reticular pseudodrusen (5 in the nonneovascular fellow eye, 2 in the study eye before developing NV). Six (75%) patients in the affected neovascular eye and 6 (75%) in the fellow nonneovascular eye had choroidal thickness age-related macular degeneration, occurring almost exclusively in patients with reticular pseudodrusen and thin choroids.

    Attention-directing cues presented at fixation evoke several lateralized event-related potential (ERP) components prior to the onset of visual targets. These components have been associated with the control of visuo-spatial attention, but the neuro-cognitive operations and neural generators of the components are still largely unknown. Here, we isolated cue-elicited ERP activity in different ways to home in on different neuro-cognitive operations and to gain a better understanding about the possible neuroanatomical sources of the cue-elicited ERP activities. To isolate lateralized cue-ERP activity, we compared shift-left and shift-right cue ERPs to shift-up cue ERPs. To measure all of the ERP activity related to attentional control, including spatially nonspecific activity that is removed in the process of isolating lateralized cue-ERP components, we compared shift-cue ERPs to neutral-cue (i.e., no-shift) ERPs. Isolated lateralized-ERP activity was seen in the contralateral-occipital lobe in the early phase of the cue-target interval and in the ipsilateral-occipital lobe in the late phase. The later, ipsilateral activity indicates that the late directing attention positivity (LDAP) reflected processing of the to-be-ignored location. The neutral-cue isolation revealed a shift-related positivity over posterior scalp regions and a shift-related negativity over more anterior scalp regions. The spatio-temporal sequence of shift-related activity observed on the scalp, together with estimates of distributed source activity underlying the shift-related ERP components, indicated that frontal and parietal regions of cortex participated in the control of attention and led to pre-target biasing in visual cortical areas.

    An increasing percentage of college students report being affected by ADHD behaviors, and this population is at increased risk of experiencing negative consequences associated with alcohol consumption. However, specific factors motivating alcohol consumption and contributing to negative outcomes among these individuals are not well understood. Recent work suggests alcohol expectancies may interact with ADHD behaviors to influence negative drinking-related outcomes among those with elevated inattention and/or hyperactivity-impulsivity. Seven-hundred-forty emerging adults (M age = 19.13 [SD = 2.25] years; 72.1% female; 85.8% Caucasian) enrolled in two public universities in the Southeast and Midwest USA completed the Brief Comprehensive Effects of Alcohol Survey (B-CEOA) and provided self-reports of ADHD symptoms and drinking-related outcomes. Multiple mediation analyses were conducted to evaluate effects of ADHD behaviors (i.e., hyperactivity-impulsivity, and inattention) and related impairment in major life domains (e.g., social interactions, occupational and educational activities, fulfillment of daily responsibilities) on drinking-related outcomes via positive and negative alcohol expectancies, controlling for sex, age, co-occurring oppositional behaviors, and data collection site. Inattention, hyperactivity-impulsivity, and impairment directly predicted both personal and social problems consequent to alcohol use. Effects of ADHD behaviors and impairment on drinking-related personal and social problems were partially mediated by positive expectancies. Findings are consistent with and extend prior work supporting a role of positive alcohol expectancies in alcohol-related negative outcomes among college students experiencing mild to moderate symptoms of ADHD.

    Child oral health-related quality of life (COHRQoL) has been increasingly assessed. However, the full relationship between gingivitis and COHRQoL has been assessed by only a small number of studies. This study aims to assess the association between gingival bleeding and how a child perceives its OHRQoL. This cross-sectional study used multistage random sampling to enroll 1,134 12-year-old schoolchildren from Santa Maria, a southern city in Brazil. Participants were examined for gingival bleeding according to the community periodontal index criteria, a full-mouth clinical examination of six sites per tooth. COHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11- to 14-Year-Old Children (CPQ11-14), and data on socioeconomic status were collected. Multilevel Poisson regression models fitted the association of gingivitis with overall and domain-specific CPQ11-14 scores. In general, children with bleeding in ≥15% of sites had higher total CPQ11-14 scores and domain-specific scores than their counterparts. This association persisted after adjustment for other potential confounders. The presence and extent of gingival bleeding was associated mainly with emotional limitation domains of the CPQ11-14; those with extended levels of gingivitis had a 1.20 times higher mean score than those with low-level/no gingival bleeding (rate ratio = 1.20; 95% confidence interval = 1.10 to 1.31). The present results indicate that the presence of extensive levels of gingivitis might be negatively associated with how children perceive their oral health and their daily life.

    Narcolepsy is a disabling disease with a delayed diagnosis. At least 3 years before the disorder identification, several comorbidities can be observed in patients with narcolepsy. The early recognition of narcolepsy symptoms may improve long-term prognosis of the patients. Thus, we aimed to investigate the prevalence of the symptoms associated with narcolepsy and its social and psychological association in a sample of Sao Paulo city inhabitants. We performed a cross-sectional evaluation with 1,008 individuals from the Sao Paulo Epidemiologic Sleep Study (EPISONO). Excessive daytime sleepiness (EDS) was assessed by the Epworth Sleepiness Scale. Volunteers were also asked about the occurrence of cataplectic-like, hypnagogic or hypnopompic hallucinations, and sleep paralysis symptoms. The participants underwent a full-night polysomnography and completed questionnaires about psychological, demographic, and quality of life parameters. We observed a prevalence of 39.2% of EDS, 15.0% of cataplectic-like symptom, 9.2% of hypnagogic or hypnopompic hallucinations, and 14.9% of sleep paralysis in Sao Paulo city inhabitants. A frequency of 6.9% was observed when EDS and cataplectic-like symptoms were grouped. The other associations were EDS + hallucinations (4.7%) and EDS + sleep paralysis (7.5%). Symptomatic participants were predominantly women and younger compared with patients without any narcolepsy symptom (n = 451). Narcolepsy symptomatology was also associated with a poor quality of life and symptoms of depression, anxiety, and fatigue. Narcolepsy-related symptoms are associated with poor quality of life and worse psychological parameters. © 2015 American Academy of Sleep Medicine.

    Malnutrition in childhood cancer patients has been associated with lower health-related quality of life (HRQOL). However, this association has never actually been tested. Therefore, we aimed to determine the association between nutritional status and HRQOL in children with cancer. In 104 children, aged 2-18 years and diagnosed with hematological, solid, or brain malignancies, nutritional status and HRQOL were assessed at diagnosis and at 3, 6, and 12 months using the child- and parent-report versions of the PedsQL 4.0 Generic scale and the PedsQL 3.0 Cancer Module. Scores on both scales range from 0 to 100. Undernourished children (body mass index (BMI) or fat-free mass children on the domains physical functioning (-13.3), social functioning (-7.0), cancer summary scale (-5.9), and nausea (-14.7). Overnourished children (BMI or fat mass >2 SDS) reported lower scores on emotional (-8.0) and cognitive functioning (-9.2) and on the cancer summary scale (-6.6), whereas parent-report scores were lower on social functioning (-7.5). Weight loss (>0.5 SDS) was associated with lower scores on physical functioning (-13.9 child-report and -10.7 parent-report), emotional (-7.4) and social functioning (-6.0) (child-report), pain (-11.6), and nausea (-7.8) (parent-report). Parents reported worse social functioning and more pain in children with weight gain (>0.5 SDS) compared with children with stable weight status. Undernutrition and weight loss were associated with worse physical and social functioning, whereas overnutrition and weight gain affected the emotional and social domains of HRQL. Interventions that improve nutritional status may contribute to enhanced health outcomes in children with cancer.

    Climate forecasts predict an increase in frequency and intensity of wildfires. Associations between health outcomes and population exposure to smoke from Washington 2012 wildfires were compared using surface monitors, chemical-weather models, and a novel method blending three exposure information sources. The association between smoke particulate matter ≤2.5 μm in diameter (PM2.5) and cardiopulmonary hospital admissions occurring in Washington from 1 July to 31 October 2012 was evaluated using a time-stratified case-crossover design. Hospital admissions aggregated by ZIP code were linked with population-weighted daily average concentrations of smoke PM2.5 estimated using three distinct methods: a simulation with the Weather Research and Forecasting with Chemistry (WRF-Chem) model, a kriged interpolation of PM2.5 measurements from surface monitors, and a geographically weighted ridge regression (GWR) that blended inputs from WRF-Chem, satellite observations of aerosol optical depth, and kriged PM2.5. A 10 μg/m3 increase in GWR smoke PM2.5 was associated with an 8% increased risk in asthma-related hospital admissions (odds ratio (OR): 1.076, 95% confidence interval (CI): 1.019–1.136); other smoke estimation methods yielded similar results. However, point estimates for chronic obstructive pulmonary disease (COPD) differed by smoke PM2.5 exposure method: a 10 μg/m3 increase using GWR was significantly associated with increased risk of COPD (OR: 1.084, 95%CI: 1.026–1.145) and not significant using WRF-Chem (OR: 0.986, 95%CI: 0.931–1.045). The magnitude (OR) and uncertainty (95%CI) of associations between smoke PM2.5 and hospital admissions were dependent on estimation method used and outcome evaluated. Choice of smoke exposure estimation method used can impact the overall conclusion of the study. PMID:28868515

    Obesity is a major concern in public health. The fact that most teenagers stop contacting the health system during this period of life prevents detection of this problem and its associated morbidity. The aim of this study is to measure the prevalence of obesity at 18. We also aimed to detect overweight, cardiovascular risk factors (CVRF) and association with CVRF in parents and siblings. The research includes 153 children followed up to 18 years old in a community health center. Measures of body mass index (BMI), waist perimeter, CVRF, and familiar history were taken. The prevalence of obesity in our study group was 7.18%, (IC: 3.0-11.0), (6.25% male and 7.86% female). The prevalence of overweight was 18.3% (IC: 11.9-24.0), (26.56% male and 12.35% female). A familiy history of CVRF was found in 53.9% (IC: 46.1-61.9) of cases, including high blood pressure (25%), obesity (23.6%), dyslipemia (21.7%), and diabetes (7.2%). This finding was more prevalent in the obesity group (72.72%) than in those with overweight only (64.2%), or with normal weight (49.59%). A family history of obesity and diabetes in first-degree relatives was associated to obesity in the study group. Also, a family history of high blood pressure was associated to the presence of high blood pressure in this group. In order to detect obesity, overweight, and associated complications in young adults, specific attention to children and siblings of persons who present risk factors is recommended. Those with high blood pressure, diabetes or obesity have the higher risk. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    Age-related macular degeneration is the leading cause of blindness among the adult population in the developed world. To further the understanding of this disease, we have studied the genetically isolated Amish population of Ohio and Indiana. Cumulative genetic risk scores were calculated using the 19 known allelic associations. Exome sequencing was performed in three members of a small Amish family with AMD who lacked the common risk alleles in complement factor H (CFH) and ARMS2/HTRA1. Follow-up genotyping and association analysis was performed in a cohort of 973 Amish individuals, including 95 with self-reported AMD. The cumulative genetic risk score analysis generated a mean genetic risk score of 1.12 (95% confidence interval [CI]: 1.10, 1.13) in the Amish controls and 1.18 (95% CI: 1.13, 1.22) in the Amish cases. This mean difference in genetic risk scores is statistically significant (P = 0.0042). Exome sequencing identified a rare variant (P503A) in CFH. Association analysis in the remainder of the Amish sample revealed that the P503A variant is significantly associated with AMD (P = 9.27 × 10(-13)). Variant P503A was absent when evaluated in a cohort of 791 elderly non-Amish controls, and 1456 non-Amish cases. Data from the cumulative genetic risk score analysis suggests that the variants reported by the AMDGene consortium account for a smaller genetic burden of disease in the Amish compared with the non-Amish Caucasian population. Using exome sequencing data, we identified a novel missense mutation that is shared among a densely affected nuclear Amish family and located in a gene that has been previously implicated in AMD risk.

    Full Text Available BACKGROUND AND AIM: Metabolic syndrome (MetS, albuminuria, and the Framingham Risk Score (FRS are significant predictors for cardiovascular disease (CVD. However, the relationship and clinical significance of these CVD predictors in individuals with a family history of end-stage renal disease (ESRD are unclear. We investigated the association of relatives of hemodialysis (HD patients with MetS, albuminuria, and the FRS. METHODS: One hundred and sixty-six relatives of HD patients and 374 age- and sex- matched community controls were enrolled. MetS was defined using the Adult Treatment Panel III for Asians. Albuminuria was defined as urine albumin-to-creatinine ratio ≥ 30 mg/g. CVD risk was evaluated by the FRS. RESULTS: A significantly higher prevalence of MetS (19.9% vs. 12.5%, P = 0.026, albuminuria (12.7% vs. 5.1%, P = 0.002 and high FRS risk ≥ 10% of 10-year risk (15.7% vs. 8.5%, P = 0.013 was found in relatives of HD patients compared to their counterpart controls. In multivariate analysis, being relatives of HD patients (vs. controls was an independent determinant for MetS (odds ratio [OR], 1.785; 95% confidence interval [CI], 1.045 to 3.050, albuminuria (OR, 2.891; 95% CI, 1.431 to 5.841, and high FRS risk (OR, 1.863; 95% CI, 1.015 to 3.418. Higher low-density lipoprotein cholesterol (OR, 1.034; 95% CI, 1.017 to 1.052 and betel nut chewing (OR, 13.994; 95% CI, 3.384 to 57.871 were independent determinants for having a high FRS risk in relatives of HD patients. CONCLUSIONS: Being relatives of HD patients was independently associated with MetS, albuminuria and high FRS risk, suggesting family members of ESRD patients may have higher CVD risks through the interactions of renal risk factors. Proactive surveillance of these CVD predictors and preventive strategies should be targeted to this high-risk population.

    Objective A current neuroanatomical model of anxiety posits that greater structural connectivity between the amygdala and ventral prefrontal cortex (vPFC) facilitates regulatory control over the amygdala and helps reduce anxiety. However, some neuroimaging studies have reported contradictory findings, demonstrating a positive rather than negative association between trait anxiety and amygdala-vPFC white matter integrity. To help reconcile these findings, we tested the regulatory hypothesis of anxiety circuitry using aging as a model of white matter decline in the amygdala-vPFC pathway. Methods We used probabilistic tractography to trace connections between the amygdala and vPFC in 21 younger, 18 middle-aged, and 15 healthy older adults. The resulting tract estimates were used to extract three indices of white-matter integrity: fractional anisotropy (FA), radial diffusivity (RD) and axial diffusivity (AD). The relationship between these amygdala-vPFC structural connectivity measures and age and State-Trait Anxiety Inventory (STAI) scores were assessed. Results The tractography results revealed age-related decline in the FA (p = .005) and radial diffusivity (p = .002) of the amygdala-vPFC pathway. Contrary to the regulatory hypothesis, we found a positive rather than negative association between trait anxiety and right amygdala-vPFC FA (p = .01). Conclusion These findings argue against the notion that greater amygdala-vPFC structural integrity facilitates better anxiety outcomes in healthy adults. Instead, our results suggest that white matter degeneration in this network relates to lower anxiety in older adults. PMID:24635708

    It has been suggested that the serotonergic systems are associated with anger and aggressive behaviors. We investigated the association between several single nucleotide polymorphisms in the serotonergic genes and anger-related personality traits. A total of 228 healthy female Korean women participated in this study. All subjects were assessed with the State-Trait Anger Expression Inventory (STAXI) and were genotyped for 3 polymorphisms: serotonin transporter (5-HTT) gene-linked polymorphic region (5-HTTLPR), tryptophan hydroxylase 1 (TPH1) A218C, and TPH2 G-703T. The Anger Expression-Out (AX-Out) subscale scores of the STAXI differed significantly between the genotypes for the TPH2 G-703T polymorphism (F = 4.825, p = 0.009). G/G homozygous subjects scored significantly higher on the AX-Out subscale than those with the G/T genotype. However, no significant differences were observed in the relationships between the STAXI subscale scores of subjects with other polymorphisms. This study suggests that the TPH2 G-703T polymorphism might contribute to anger-related traits, especially to the expression of anger. (c) 2010 S. Karger AG, Basel.

    Staphylococcus epidermidis biofilm causes device-related meningitis in neurosurgical patients. This study assessed the contribution of polysaccharide and protein to the development of a strong biofilm-positive phenotype in four S. epidermidis isolates associated with probable device-related meningitis, under varying environmental conditions. RT-PCR analysis of the intercellular adhesion operon (icaADBC) and assessment of polysaccharide intercellular adhesin (PIA) production indicated a correlation between increased icaA transcription and PIA production in ica(+) isolates grown in medium with 4 % ethanol and 4 % NaCl. Treatment of biofilm with sodium metaperiodate caused dispersion of adhered cells (P <0.0001), indicating involvement of PIA. Transcriptional levels of protein factors revealed that atlE transcription levels were similar in all isolates, whilst aap levels were variable, with induction being seen in two isolates following growth in the presence of alcohol or salt. Transcription of agr did not influence protein expression and RNAIII transcription varied among the strains. Although aap transcription was induced, the treatment of biofilm with proteinase K did not always disperse the biofilm. Our data suggest that, among the three ica(+) S. epidermidis isolates clinically associated with meningitis that were studied, PIA contributed to the strong biofilm-positive phenotype, whereas protein factors appeared to have a secondary role.

    To examine the associations between objective health indicators and high need for recovery (NFR) after work, one of the subjective presentations of work related-fatigue, among apparently healthy workers in modern workplaces. From October to December, 2007, an annual health examination was performed for the workers from an electronics manufacturing factory in Taiwan. Health records of 1216 workers with a relatively homogeneous socioeconomic status were used for analysis. The health checkups included personal and NFR scale questionnaires, physical examinations, blood tests for biochemistry and hematology. The workers within the top tertile NFR score were defined as high-NFR workers. After adjusted for potential confounders, the workers with elevated alanine aminotransferase (ALT) and central obesity had a significantly higher NFR after work, with increased risks of 1.4-fold [95% confidence interval (CI) = 1.01-2.0] and 1.8-fold (95% CI = 1.2-2.7), respectively. Shiftworkers had a 2.0-fold (95% CI = 1.5-2.6) increased risk for high-NFR. The associations between high-NFR and lipid profiles, blood sugar, hematology indexes or blood pressure were insignificant after controlling for confounders. For apparently healthy workers, high NFR after work is not simply a subjective experience. Objective health measures, such as elevated ALT and increased waist circumference, should be carefully evaluated for the apparently healthy workers having a higher NFR after work.

    The cardio-ankle vascular index is a measure of arterial stiffness, whereas oxidative stress underlies arterial pathology. This study aimed to investigate the association between the cardio-ankle vascular index and antioxidant-related gene polymorphisms in young Russians. A total of 89 patients (mean age, 21.6 years) were examined by the cardio-ankle vascular index and for 15 gene polymorphisms related to antioxidant enzymes including FMO3 (flavin-containing monooxygenase 3), GPX1 (glutathione peroxidase 1), and GPX4 (glutathione peroxidase 4). A higher cardio-ankle vascular index level was detected in carriers with the KK-genotype of FMO3 polymorphism rs2266782 than in those without (mean levels: 6.2 versus 5.6, respectively, pcardio-ankle vascular index level was seen in carriers with the CC-genotype of GPX4 polymorphism rs713041 than in those without (6.0 versus 5.5, respectively, pcardio-ankle vascular index levels and the other gene polymorphisms. Although carriers with the LL-genotype of GPX1 polymorphism rs1050450 showed a higher diastolic blood pressure level than those without, the polymorphism did not affect the cardio-ankle vascular index level. This study showed a significant association between rs2266782 and rs713041 polymorphisms and arterial stiffness, as measured by the cardio-ankle vascular index, in young Russians. The pathways utilised by antioxidant enzymes may be responsible for early arterial stiffening in the Russian population.

    Leptospirosis is a cosmopolitan infectious disease that causes severe reproductive disorders in cattle, especially those related to abortion. This disease has rodents as main reservoirs; however, cattle are responsible for maintenance of the disease. Thus, the aim of this study was to identify the factors associated with infection and cause-effect relation of leptospirosis in dairy herds from Southern of Brazil. Serum samples of 1242 cows were collected from herds classified as of medium and high density, and tested by microscopic agglutination test (MAT). These farms were located in the West part of Santa Catarina State (Brazil). A total of 80 cows (6.44%) were considered positives for the infection with titration of 1:100. Using a multivariate analysis, we identified two factors associated to bovine leptospirosis: dog access to pastures (p leptospirosis. Thus, we conclude that leptospirosis is prevalent in dairy cattle in the west part of Santa Catarina state, as well as the access of dogs to pastures and contact of rodents with feed increase the chance of cattle infection by Leptospira spp. Copyright © 2017 Elsevier Ltd.

    Students mandated for intervention following an alcohol-related sanction event often reduce their drinking prior to intervention. Knowing the determinants of self-initiated change may help identify intervention targets for individuals who do not reduce their drinking. Guided by self-regulation theory, we tested whether fewer past alcohol consequences and higher descriptive and injunctive norms would be associated with higher levels of postsanction drinking. College students referred for a campus alcohol violation (N = 658, 64% male) reported on their drinking during the month before and after their sanction event. Results show that postsanction drinking was significantly lower than presanction drinking across 4 outcomes: (a) drinks per drinking day, (b) drinks per week, (c) peak drinks, and (d) peak blood alcohol concentration. Hypothesized social influence variables (i.e., descriptive and injunctive norms) were consistently associated with all 4 drinking outcomes; that is, students who perceived that their friends drank more and held more accepting views of drinking were less reactive to alcohol-related sanctions. Past consequences of drinking did not consistently predict subsequent drinking. Therefore, we conclude that alcohol interventions for mandated students should target both descriptive and injunctive norms to optimize their efficacy.

    Full Text Available Severe myelosuppression is a serious concern in the management of rheumatic disease patients receiving methotrexate (MTX therapy. This study was intended to explore factors associated with the development of MTX-related myelosuppression and its disease severity.We retrospectively examined a total of 40 cases of MTX-related myelosuppression that had been filed in the registries of participating rheumatology and hematology divisions. Data before onset were compared with those of 120 controls matched for age and sex. Cytopenia was graded according to the National Cancer Institute criteria for adverse events. Data before and at onset were compared between the severe and non-severe groups.Non-use of folic acid supplements, concurrent medications, and low renal function were significantly associated with the development of myelosuppression (p < 0.001, p < 0.001, and p = 0.002, respectively. In addition, significantly lower MTX dosages, higher blood cell counts, and lower hemoglobin levels were seen in the myelosuppression group (p < 0.001. No patients exhibited leukocytopenia, neutropenia, or thrombocytopenia in routine blood monitoring taken within the past month. One-fourth developed myelosuppression within the first two months (an early-onset period. Myelosuppression was severe in approximately 40% of patients. Hypoalbuminemia and non-use of folic acid supplements were significantly associated with the severity of pancytopenia (p = 0.001 and 0.008, respectively. Besides these two factors, early onset and the use of lower doses of MTX were significantly associated with the severity of neutropenia (p = 0.003, 0.007, 0.003, and 0.002, respectively.Myelosuppression can occur abruptly at any time during low-dose MTX therapy, but severe neutropenia is more likely to occur in the early-onset period of this therapy. Contrary to our expectations, disease severity was not dependent on MTX doses. Serum albumin levels and folic acid supplementation are the

    To investigate the prevalence of playing-related musculoskeletal disorders (PRMD) and associated factors among violinists from the state of Rio de Janeiro, Brazil. This cross-sectional study included 106 violinists from eight cities in the state of Rio de Janeiro. Sociodemographic and musical characteristic data, pain symptoms, and upper-limb functionality were collected using the DASH and the Standardized Nordic Questionnaires. The associations between musculoskeletal complaints and possible predictors were analyzed by binary logistic regression. Of the 106 surveyed violin players, 86.8% reported at least one painful area in the last 12 months and 77.4% in the last week. These symptoms were responsible for the temporary interruption of musical activity in 8.1% of musicians. More than 50% of violinists showed dysfunctional upper limbs according to the DASH optional module. Women were more likely to develop musculoskeletal disorders (OR 4.4, CI 1.9-10.0, p<0.001). In addition, older musicians were more likely to report pain in the last 7 days (OR 3.3, CI 5.1-10.97; p=0.04) and also had higher scores on the DASH (OR 1.8, CI 1.1-3.1; p=0.01). Other factors associated with the development of PRMD were body mass index, practice hours per week, and final DASH score. Violinists living and working in the state of Rio de Janeiro have a high prevalence of PRMD, especially women and older musicians.

All participants underwent a standardized interview, evaluation of blood lead concentration, and a comprehensive ophthalmic examination. Digital fundus photographs (45° were taken of both eyes under physiological mydriasis. All fundus photographs were graded using an international classification and grading system.Mean blood lead levels were 3.15 μg/dL in men and 2.27 μg/dL in women (P < 0.001. After adjusting for potential confounders including age, gender, smoking status, total cholesterol levels, triglyceride levels, heart problems and strokes, the adjusted odds ratio (OR in women for any AMD was 1.86 (95% Confidence Interval [CI], 1.03-3.36 and for early AMD was 1.92 (95% CI, 1.06-3.48, for those in the highest quintile of lead level compared with the lowest quintile. In men, however, blood lead level was not significantly associated with AMD.Blood lead levels were higher in men, but were only associated with AMD in women. Increased levels of blood lead may be involved in the pathogenesis of AMD development in women.

    A chronically elevated white blood cell (WBC) count is a risk factor for morbidity and mortality. The present research tests whether facets of impulsivity – impulsiveness, excitement-seeking, self-discipline, and deliberation – are associated with chronically elevated WBC counts. Community-dwelling participants (N=5,652) from Sardinia, Italy, completed a standard personality questionnaire and provided blood samples concurrently and again three years later. Higher scores on impulsivity, in particular impulsiveness and excitement-seeking, were related to higher total WBC counts and higher lymphocyte counts at both time points. Impulsiveness was a predictor of chronic inflammation: For every standard deviation difference in this trait, there was an almost 25% higher risk of elevated WBC counts at both time points (OR=1.23, 95% CI=1.10–1.38). These associations were mediated, in part, by smoking and body mass index. The findings demonstrate that links between psychological processes and immunity are not limited to acute stressors; stable personality dispositions are associated with a chronic inflammatory state.

    Alpha-1 antitrypsin (AAT) encoded by SERPINA1 is an acute-phase inflammation marker, and AAT deficiency (AATD) is known as one of the common genetic disorders in European populations. However, no genetic determinants to AAT levels apart from the SERPINA gene clusters have been identified to date. Here we perform a genome-wide association study of serum AAT levels followed by a two-staged replication study recruiting a total of 9,359 Japanese community-dwelling population. Three missense variants of metabolic syndrome-related genes, namely, rs671 in ALDH2, rs1169288 in HNF1A and rs1260326 in GCKR, significantly associate with AAT levels (P≤1.5 × 10(-12)). Previous reports have shown the functional relevance of ALDH2 and HNF1A to AAT. We observe a significant interaction of rs671 and alcohol consumption on AAT levels. We confirm the association between AAT and rs2896268 in SERPINA1, which is independent of known causative variants of AATD. These findings would support various AAT functions including metabolic processes.

    Full Text Available The aim of this study is to investigate the relationships between road traffic noise exposure, annoyance caused by different noise sources and validated health indicators in a cohort of 1375 adults from the region of Basel, Switzerland. Road traffic noise exposure for each study participant was determined using modelling, and annoyance from various noise sources was inquired by means of a four-point Likert scale. Regression parameters from multivariable regression models for the von Zerssen score of somatic symptoms (point symptom score increase per annoyance category showed strongest associations with annoyance from industry noise (2.36, 95% CI: 1.54, 3.17, neighbour noise (1.62, 95% CI: 1.17, 2.06 and road traffic noise (1.53, 95% CI: 1.09, 1.96. Increase in modelled noise exposure by 10 dB(A resulted in a von Zerssen symptom score increase of 0.47 (95% CI: −0.01, 0.95 units. Subsequent structural equation modelling revealed that the association between physical noise exposure and health-related quality of life (HRQOL is strongly mediated by annoyance and sleep disturbance. This study elucidates the complex interplay of different factors for the association between physical noise exposure and HRQOL.

    The prevalence of obesity in Mexican children has increased during the last decade, as has the risk of early onset metabolic disorders and cardiovascular disease. To determine the association ofAcantosis nigricans (AN)with dyslipidemia, high blood pressure, body mass index (BMI), and risk factors related to eating behavior in overweight and obese children. This transverse analytical study, conducted in two Mexico City primary schools, included 300 boys and girls. Information was gathered on hereditary and perinatal background. A physical examination provided data on the presence/absence of AN, blood pressure, weight and height. The BMI and Z-score were calculated. The serum concentration of glucose, cholesterol and triglycerides was quantified and the lipoprotein profile determined. The prevalence of AN was 41.7%. An association was found between ANand risk factors for cardiovascular disease, including BMI (rS 0.432; p 48%) (RM: 3.591; p = 0.001). A high prevalence of ANwas found in overweight and obese children. There was an association between ANand risk factors of cardiovascular disease, including Z-score, BMI, dyslipidemia, and high blood pressure.

    Association-based linkage disequilibrium (LD) mapping is an increasingly important tool for localizing genes that show potential influence on human aging and longevity. As haplotypes contain more LD information than single markers, a haplotype-based LD approach can have increased power in detecting associations as well as increased robustness in statistical testing. In this paper, we develop a new statistical model to estimate haplotype relative risks (HRRs) on human survival using unphased multilocus genotype data from unrelated individuals in cross-sectional studies. Based on the proportional hazard assumption, the model can estimate haplotype risk and frequency parameters, incorporate observed covariates, assess interactions between haplotypes and the covariates, and investigate the modes of gene function. By introducing population survival information available from population statistics, we are able to develop a procedure that carries out the parameter estimation using a nonparametric baseline hazard function and estimates sex-specific HRRs to infer gene-sex interaction. We also evaluate the haplotype effects on human survival while taking into account individual heterogeneity in the unobserved genetic and nongenetic factors or frailty by introducing the gamma-distributed frailty into the survival function. After model validation by computer simulation, we apply our method to an empirical data set to measure haplotype effects on human survival and to estimate haplotype frequencies at birth and over the observed ages. Results from both simulation and model application indicate that our survival analysis model is an efficient method for inferring haplotype effects on human survival in population-based association studies.

    Full Text Available Multiple Sclerosis associated neuropsychiatric disorders include major depression (MD, obsessive-compulsive disorder (OCD, bipolar affective disorder, euphoria, pseudobulbar affect, psychosis, and personality change. Magnetic Resonance Imaging (MRI studies focused mainly on identifying morphostructural correlates of MD; only a few anecdotal cases on OCD associated to MS (OCD-MS, euphoria, pseudobulbar affect, psychosis, personality change, and one research article on MRI abnormalities in OCD-MS have been published. Therefore, in the present review we will report mainly on neuroimaging abnormalities found in MS patients with MD and OCD. All together, the studies on MD associated to MS suggest that, in this disease, depression is linked to a damage involving mainly frontotemporal regions either with discrete lesions (with those visible in T1 weighted images playing a more significant role or subtle normal appearing white matter abnormalities. Hippocampal atrophy, as well, seems to be involved in MS related depression. It is conceivable that grey matter pathology (i.e., global and regional atrophy, cortical lesions, which occurs early in the course of disease, may involve several areas including the dorsolateral prefrontal cortex, the orbitofrontal cortex, and the anterior cingulate cortex whose disruption is currently thought to explain late-life depression. Further MRI studies are necessary to better elucidate OCD pathogenesis in MS.

    Maciej Trzaskowski

    Full Text Available BACKGROUND: Twin studies have shown that anxiety in a general population sample of children involves both domain-general and trait-specific genetic effects. For this reason, in an attempt to identify genes responsible for these effects, we investigated domain-general and trait-specific genetic associations in the first genome-wide association (GWA study on anxiety-related behaviours (ARBs in childhood. METHODS: The sample included 2810 7-year-olds drawn from the Twins Early Development Study (TEDS with data available for parent-rated anxiety and genome-wide DNA markers. The measure was the Anxiety-Related Behaviours Questionnaire (ARBQ, which assesses four anxiety traits and also yields a general anxiety composite. Affymetrix GeneChip 6.0 DNA arrays were used to genotype nearly 700,000 single-nucleotide polymorphisms (SNPs, and IMPUTE v2 was used to impute more than 1 million SNPs. Several GWA associations from this discovery sample were followed up in another TEDS sample of 4804 children. In addition, Genome-wide Complex Trait Analysis (GCTA was used on the discovery sample, to estimate the total amount of variance in ARBs that can be accounted for by SNPs on the array. RESULTS: No SNP associations met the demanding criterion of genome-wide significance that corrects for multiple testing across the genome (p<5×10(-8. Attempts to replicate the top associations did not yield significant results. In contrast to the substantial twin study estimates of heritability which ranged from 0.50 (0.03 to 0.61 (0.01, the GCTA estimates of phenotypic variance accounted for by the SNPs were much lower 0.01 (0.11 to 0.19 (0.12. CONCLUSIONS: Taken together, these GWAS and GCTA results suggest that anxiety--similar to height, weight and intelligence--is affected by many genetic variants of small effect, but unlike these other prototypical polygenic traits, genetic influence on anxiety is not well tagged by common SNPs.

    The aim of the study was to investigate the associations between physical activity (PA)-related miRNAs and metabolic syndrome (MetS). A case-control study was conducted in 209 subjects with MetS and 234 controls. The MetS was defined by the International Diabetes Foundation (IDF) criteria of 2005. Serum PA-related miRNAs were detected by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) assays. Association analysis was performed by logistic regression models. The expression levels of miR-126 and miR-130a were lower in the highest metabolic equivalent hours per week (MET-h/week) quartile than in the lowest quartile [miR-126: Q5 vs. Q1, median (5-95%), 1.67 (0.54, 2.45) vs. 1.35 (0.45, 2.45), p=0.012; miR-130a: Q5 vs. Q1, median (5-95%), 0.90 (0.44, 1.35) vs. 0.53 (0.26, 1.01), p<0.001]. However, miR-197 exhibited a trend with increased MET-h/week [Q5 vs. Q1, median (5-95%), 1.35 (0.45, 2.63) vs. 2.18 (0.87, 4.77), p=0.009]. MiR-126 increased MetS risk significantly while the effect of miR-197 was opposite (miR-126: OR=1.37, 95% CI 1.07-1.75; p=0.012; miR-197: OR=0.68, 95% CI 0.51-0.92; p=0.010). Individuals in the highest MET-h/week quartile had lower prevalence and odds rate of MetS compared with those in the lowest quartile (Q4 vs. Q1: OR=0.58, 95% CI 0.33-1.05; p for trend=0.026). However, further adjustment of both PA associated miRNAs abolished that association. All these results suggested that the association between PA and MetS risk might partly depend on miR-126 and miR-197. © Georg Thieme Verlag KG Stuttgart · New York.

We performed a genome-wide association study and analysis of known genetic risk loci for AD dementia using neuropathologic data from 4,914 brain autopsies. Neuropathologic data were used to define clinico-pathologic AD dementia or controls, assess core neuropathologic features of AD (neuritic plaques, NPs; neurofibrillary tangles, NFTs, and evaluate commonly co-morbid neuropathologic changes: cerebral amyloid angiopathy (CAA, Lewy body disease (LBD, hippocampal sclerosis of the elderly (HS, and vascular brain injury (VBI. Genome-wide significance was observed for clinico-pathologic AD dementia, NPs, NFTs, CAA, and LBD with a number of variants in and around the apolipoprotein E gene (APOE. GalNAc transferase 7 (GALNT7, ATP-Binding Cassette, Sub-Family G (WHITE, Member 1 (ABCG1, and an intergenic region on chromosome 9 were associated with NP score; and Potassium Large Conductance Calcium-Activated Channel, Subfamily M, Beta Member 2 (KCNMB2 was strongly associated with HS. Twelve of the 21 non-APOE genetic risk loci for clinically-defined AD dementia were confirmed in our clinico-pathologic sample: CR1, BIN1, CLU, MS4A6A, PICALM, ABCA7, CD33, PTK2B, SORL1, MEF2C, ZCWPW1, and CASS4 with 9 of these 12 loci showing larger odds ratio in the clinico-pathologic sample. Correlation of effect sizes for risk of AD dementia with effect size for NFTs or NPs showed positive correlation, while those for risk of VBI showed a moderate negative correlation. The other co-morbid neuropathologic features showed only nominal association with the known AD loci. Our results discovered new genetic associations with specific neuropathologic features and aligned known genetic risk for AD dementia with specific neuropathologic changes in the largest brain autopsy study of AD and related

    Full Text Available Abstract Background Mitochondrial dysfunction (MtD has been observed in approximately five percent of children with autism spectrum disorders (ASD. MtD could impair highly energy-dependent processes such as neurodevelopment, thereby contributing to autism. Most of the previous studies of MtD in autism have been restricted to the biomarkers of energy metabolism, while most of the genetic studies have been based on mutations in the mitochondrial DNA (mtDNA. Despite the mtDNA, most of the proteins essential for mitochondrial replication and function are encoded by the genomic DNA; so far, there have been very few studies of those genes. Therefore, we carried out a detailed study involving gene expression and genetic association studies of genes related to diverse mitochondrial functions. Methods For gene expression analysis, postmortem brain tissues (anterior cingulate gyrus (ACG, motor cortex (MC and thalamus (THL from autism patients (n=8 and controls (n=10 were obtained from the Autism Tissue Program (Princeton, NJ, USA. Quantitative real-time PCR arrays were used to quantify the expression of 84 genes related to diverse functions of mitochondria, including biogenesis, transport, translocation and apoptosis. We used the delta delta Ct (∆∆Ct method for quantification of gene expression. DNA samples from 841 Caucasian and 188 Japanese families were used in the association study of genes selected from the gene expression analysis. FBAT was used to examine genetic association with autism. Results Several genes showed brain region-specific expression alterations in autism patients compared to controls. Metaxin 2 (MTX2, neurofilament, light polypeptide (NEFL and solute carrier family 25, member 27 (SLC25A27 showed consistently reduced expression in the ACG, MC and THL of autism patients. NEFL (P = 0.038; Z-score 2.066 and SLC25A27 (P = 0.046; Z-score 1.990 showed genetic association with autism in Caucasian and Japanese samples, respectively. The

    Full Text Available Abstract Background Boar taint is an unpleasant odour and flavour of the meat from some uncastrated male pigs primarily caused by elevated levels of androstenone and skatole in adipose tissue. Androstenone is produced in the same biochemical pathway as testosterone and estrogens, which represents a particular challenge when selecting against high levels of androstenone in the breeding programme, without simultaneously decreasing levels of other steroids. Detection of single nucleotide polymorphisms (SNPs associated with compounds affecting boar taint is important both for gaining a better understanding of the complex regulation of the trait and for the purpose of identifying markers that can be used to improve the gain of breeding. The beneficial SNPs to be used in breeding would have the combinational effects of reducing levels of boar taint without affecting fertility of the animals. The aim of this study was to detect SNPs in boar taint candidate genes and to perform association studies for both single SNPs and haplotypes with levels of boar taint compounds and phenotypes related to reproduction. Results An association study involving 275 SNPs in 121 genes and compounds related to boar taint and reproduction were carried out in Duroc and Norwegian Landrace boars. Phenotypes investigated were levels of androstenone, skatole and indole in adipose tissue, levels of androstenone, testosterone, estrone sulphate and 17β-estradiol in plasma, and length of bulbo urethralis gland. The SNPs were genotyped in more than 2800 individuals and several SNPs were found to be significantly (LRT > 5.4 associated with the different phenotypes. Genes with significant SNPs in either of the traits investigated include cytochrome P450 members CYP2E1, CYP21, CYP2D6 and CYP2C49, steroid 5α-reductase SRD5A2, nuclear receptor NGFIB, catenin CTNND1, BRCA1 associated protein BAP1 and hyaluronoglucosaminidase HYAL2. Haplotype analysis provided additional evidence for an

    , except for few specific cases, the shapes of the binding pockets have relatively low weights in the determination of the affinity profiles of proteins. Since the MAF profile is closely related to the target specificity of ligand binding sites we can conclude that the shape of the binding site is not a pivotal factor in selecting drug targets. Nonetheless, based on strong specific associations between certain MAF profiles and specific geometric descriptors we identified, the shapes of the binding sites do have a crucial role in virtual drug design for certain drug categories, including morphine derivatives, benzodiazepines, barbiturates and antihistamines.

    Both female reproductive hormones and childhood sexual abuse (CSA) are implicated in migraine and in menstrually related mood disorders (MRMD). We examined the association of migraine, including migraine with aura (MA), and history of MRMD or CSA. A total of 174 women (mean age 33.9 ± 7.6 years) in this cross-sectional study were evaluated for (1) current MRMD using prospective daily ratings; (2) history of CSA using structured interview; and (3) MA and migraine without aura using the International Classification of Headaches Disorders II criteria. Ninety-six women met MRMD criteria (21 of whom had history of CSA) and 78 women were non-MRMD controls (16 with CSA histories). Migraine with aura was more prevalent in women with MRMD when compared to non-MRMD controls (11/88 and 0/86, respectively, p=0.001). In MRMD women only, a CSA history was associated with higher MA rates (6/21 and 5/67, respectively, p=0.019). A combination of current MRMD diagnosis and a history CSA was associated with increased risk for MA, even after adjusting for potential confounders (odds ratio=12.08, 95% confidence interval 2.98-48.90, p<0.001). Women with MRMD may be vulnerable to the development of MA, and a history of CSA in women with a MRMD appears to increase that vulnerability. MRMDs and MA should be included among other poor mental and physical health outcomes of an abuse history. Routine screening for abuse histories would potentially improve identification of women with increased risk of experiencing abuse-related disorders.

    To study the prevalence, tomographic features, and clinical characteristics of focal choroidal excavation (FCE) in eyes with exudative age-related macular degeneration (AMD). We examined 243 consecutive eyes with exudative AMD with a prototype swept-source optical coherence tomography (OCT) system. Three-dimensional images of the macular area, covering 6 × 6 mm(2), were reconstructed by segmentation of the outer surface of the retinal pigment epithelium. Three-dimensional swept-source OCT revealed 15 excavations in 12 eyes (4.9%); 10 had a single excavation and 2 had multiple excavations (2 and 3 excavations, respectively). In multiaveraged scans, unusual choroidal tissue was found beneath 5 excavations, bridging the excavation with the outer choroidal boundary. Additionally, the suprachoroidal space was observed beneath 7 excavations-the outer choroidal boundary appeared to be pulled inward by this bridging tissue. In 9 excavations, color fundus photographs showed pigmentary disturbance. Fourteen excavations (93.3%) were located within or adjacent to the choroidal neovascularization area. Compared with eyes without FCE, in eyes with FCE, the mean age was significantly higher (P = 0.040) and mean visual acuity was significantly better (P = 0.014). In addition, polypoidal lesions were observed in 8 of 12 eyes with FCE, but they appeared to have a limited effect on either the rate of FCE (P = 0.44) or the clinical characteristics of the eyes. While FCE may be partially related to the choroidal neovascularization associated with exudative AMD, other factors may also influence this association.

    Dehydroepiandrosterone sulfate (DHEAS) declines with age and low endogenous DHEAS concentrations have been associated with obesity. In addition, DHEAS has been studied for its role in mood and wellbeing. However, limited data are available on salivary DHEAS concentrations in African Americans. Thus, we examined age-related changes in morning salivary DHEAS and the association between DHEAS and obesity risk factors among African Americans. Salivary DHEAS samples (n=170) were obtained from men and women divided into three age groups: 18 to 30 (young), 31 to 45 (middle) and 46 to 60 (older) years. Anthropometric, blood glucose, high sensitivity c-reactive protein (hsCRP), and blood pressure measures were obtained. Participants completed the Center for Epidemiologic Studies Depression (CESD), Beck Depression Inventory (BDI), Daily Hassles Scale (DHS), Perceived Stress Scale (PSS) and Pittsburgh Sleep Quality Index (PSQI) scales to assess depression, daily hassles, stress and quality of sleep, respectively. Mean salivary DHEAS concentrations decreased significantly with increasing age: mean values were 25.8 +/- 2.4, 21.9 +/- 1.9, and 14.4 +/- .9 nmol/L for young, middle, and older groups, respectively. Like DHEAS, PSQI, DHS, CESD, MAP, WC, BMI, systolic and diastolic BP and fasting blood glucose values differed significantly in the older compared to the young and middle groups. Women had significantly lower salivary DHEAS than men (P< or =.05). The age-related decline in salivary DHEAS in African Americans is associated with cardiovascular risk factors, sleep quality, hassles and mood. Whether supplementing DHEAS levels in aging African Americans will improve health remains to be determined.

    Full Text Available Introduction Coffee is among the most widely consumed beverages in the world. Several epidemiological studies have evaluated the association between coffee consumption and risk of systemic diseases; however, there is paucity of data in relation to coffee consumption and risk of eye diseases. This study aims to examine the relationship between coffee consumption and risk of age-related macular degeneration (AMD and diabetic retinopathy (DR in multiethnic population of Singapore. Materials and MethodsWe analyzed the data from 4121 study participants from the Singapore Prospective Study Program to examine the relationship of coffee to prevalence of AMD and DR. A standardized questionnaire that included information about the habitual amount of coffee consumed was completed by all study participants. Presence and severity of AMD and DR was assessed on fundus photographs using the Mutiethnic Study of Atherosclerosis Grading Protocol. ResultsThe prevalence of AMD and DR in our population was 5.4% and 32.0%, respectively. A positive history of coffee consumption was present in 77.5% of AMD population and 76.1% of DR population with majority of participants consuming 1-2 cups of coffee daily. No statistically significant association was observed between coffee consumption and odds of AMD or DR after adjusting for confounding factors [AMD: Odds Ratio (OR = 1.27, Confidence Interval (CI = 0.88-1.83, p = 0.20; DR: OR = 1.36, CI = 0.69-2.69, p = 0.37. ConclusionThis epidemiological study of a large multiethnic population data set do not support the hypothesis that habitual intake of coffee and caffeine is associated with an altered risk of AMD and DR among Asians.

    Beverage intake can influence child diet quality in a positive or negative manner depending on the beverage type and amounts consumed. Parenting practices such as role modeling and control of home beverage availability have been associated with child beverage intake, whereas examination of the influence of parental beverage nutrition knowledge has been more limited. The purpose of this study was to examine the relationships between sugar-sweetened and dairy beverage intake among children (9–12 years) and home and parental factors. A questionnaire was administered among a convenience sample of parents (n = 194) to assess beverage nutrition knowledge, beverage intake and home availability of beverages. Children completed a questionnaire to estimate usual beverage intake. Daily sugar-sweetened beverage intake by children ranged from 0.4 to 48 oz. Logistic regression analysis was used to examine relationships. Parents were mostly female, white, well educated, and employed. Home availability of sugar-sweetened and dairy beverages was positively associated with child sugar-sweetened (OR = 1.48, p = 0.03) and dairy beverage intake (OR = 1.34, p = 0.03), respectively. Parent dairy beverage intake was associated with child dairy beverage intake (OR = 1.06, p = 0.01). Parent knowledge about sugar in beverages was related to child dairy beverage intake (OR = 1.46, p = 0.02), whereas calcium/dairy knowledge and general beverage nutrition knowledge were not related to child beverage intake. Parenting practices and knowledge may play a role in determining child beverage intake. PMID:28820455

    A high falls-related mortality rate in the elderly is not exclusively related to injuries. Moreover, the risk of falls increases with urinary disorders such as nocturia. The aim of this study was to investigate the role of nocturia in falls-related long-term mortality in elderly subjects. Longitudinal study. The "Osservatorio Geriatrico Regione Campania" was a cross-sectional study performed in 1992 in Campania, a region of Southern Italy. Long-term mortality (12 years' follow-up) in 178 elderly subjects (mean age 74.0 ± 6.3 years) with falls and 1110 elderly subjects (mean age 75.2 ± 6.4 years) without falls at baseline was measured. Subjects were then stratified for the presence/absence of nocturia. In our sample, the prevalence of falls was 13.8% and the prevalence of nocturia was 45.7%. Long-term mortality was 51.3% in nonfallers and 62.9% in fallers (P < .05). In the absence of nocturia, long-term mortality was similar in nonfallers and fallers (49.0% vs 46.7%; P = .514, NS). In contrast, in the presence of nocturia, long-term mortality was higher in fallers than in nonfallers (74.5% vs 53.6%; P < .05). Cox regression analysis confirmed the predictive role of falls on long-term mortality in the presence of nocturia (hazard ratio 60; 95% confidence interval 1.01-2.57; P < .05) but not in the absence of nocturia (hazard ratio = 1.27; 95% confidence interval 0.81-1.99; P = .28). Our data suggest that falls are related to an increased risk of long-term mortality in the elderly much more in the presence of nocturia. This phenomenon is probably related to the high comorbidity that usually affects elderly subjects with nocturia. Copyright © 2012 American Medical Directors Association. Published by Elsevier Inc.

    Full Text Available Recently, ETS-related gene (ERG gene rearrangements, phosphatase tensin homologue (PTEN deletions and EGFR family aberrations were characterized as potential biomarkers for prostate cancer (PCa patient management. Although ERG gene rearrangement has been identified in approximately 50% of localized prostate cancers in western countries, the prognostic significance of this critical molecular event remains unknown in Chinese patients. Using fluorescence in situ hybridization (FISH and immunohistochemistry, we evaluated ERG, PTEN and EGFR family aberrations in a cohort of 224 Chinese prostate cancer patients diagnosed in transurethral resection of the prostate (TUR-P. Overall, ERG rearrangement was detected in 23.2% (44/190 cases, of which 54.5% (24/44 showed deletion of the 5'end of ERG. PTEN deletion was identified in 10.8% (19/176 cases. Amplification of EGFR and HER2 genes was present in 1.1% (2/178 and 5.8% (10/173 of cases, respectively. Significant correlation between ERG rearrangement and PTEN deletion was identified in this cohort. EGFR and HER2 aberrations occurred more frequently in PCas without ERG rearrangement than in those with ERG rearrangement, although this did not reach statistical significance. Overall, ERG rearrangement was associated with pre-operative PSA values (P = 0.038 and cancer-related death (P = 0.02, but not with the age, clinical T stage, Gleason score, or Ki-67 labeling index (LI. Notably, multivariate analysis including known prognostic markers revealed ERG rearrangement was an independent prognostic factor (P = 0.022. Additionally, ERG rearrangement status was helpful to identify patients with poor prognosis from PCa group with low Ki-67 LI. In summary, we reported that ERG rearrangement was associated with cancer-related death in Chinese PCa patients. Determination of ERG rearrangement status allows stratification of PCa patients into different survival categories.

    Full Text Available To determine if plasma metabolic profiles can detect differences between patients with neovascular age-related macular degeneration (NVAMD and similarly-aged controls.Metabolomic analysis using liquid chromatography with Fourier-transform mass spectrometry (LC-FTMS was performed on plasma samples from 26 NVAMD patients and 19 controls. Data were collected from mass/charge ratio (m/z 85 to 850 on a Thermo LTQ-FT mass spectrometer, and metabolic features were extracted using an adaptive processing software package. Both non-transformed and log2 transformed data were corrected using Benjamini and Hochberg False Discovery Rate (FDR to account for multiple testing. Orthogonal Partial Least Squares-Discriminant Analysis was performed to determine metabolic features that distinguished NVAMD patients from controls. Individual m/z features were matched to the Kyoto Encyclopedia of Genes and Genomes database and the Metlin metabolomics database, and metabolic pathways associated with NVAMD were identified using MetScape.Of the 1680 total m/z features detected by LC-FTMS, 94 unique m/z features were significantly different between NVAMD patients and controls using FDR (q = 0.05. A comparison of these features to those found with log2 transformed data (n = 132, q = 0.2 revealed 40 features in common, reaffirming the involvement of certain metabolites. Such metabolites included di- and tripeptides, covalently modified amino acids, bile acids, and vitamin D-related metabolites. Correlation analysis revealed associations among certain significant features, and pathway analysis demonstrated broader changes in tyrosine metabolism, sulfur amino acid metabolism, and amino acids related to urea metabolism.These data suggest that metabolomic analysis can identify a panel of individual metabolites that differ between NVAMD cases and controls. Pathway analysis can assess the involvement of certain metabolic pathways, such as tyrosine and urea metabolism, and can

    Metatarsalgia is frequently associated with hallux valgus. The aim of this study was to evaluate how the relative length and position of the first metatarsal head influenced metatarsalgia and plantar callosities beneath the lesser metatarsal heads. A retrospective analysis of the clinical data and radiographs of 102 cases was performed at a mean follow-up of 16 months after biplane interlocking osteotomies. Clinical evaluation was made using the Japanese Society for Surgery of the Foot (JSSF) hallux scale. Radiologic evaluation was made with standard weight-bearing anteroposterior radiographs, and the hallux valgus angle (HVA), intermetatarsal 1-2 angle (IMA), distal metatarsal articular angulation (DMAA), and the sesamoid position were evaluated. Relative first metatarsal length (RML) was determined according to Nilsonne/Morton's technique. The mean preoperative HVA decreased from 37 to 3 degrees, and the mean IMA from 17 to 4 degrees. The mean JSSF-hallux score improved from 56 to 96 points. The mean preoperative area of plantar callosities decreased from 3.1 to 1.5 mm(2). Sixty percent of metatarsalgia cases improved, and 85% of painless callosities disappeared postoperatively. Among radiologic parameters, postoperative RML was most significantly associated with JSSF score (P < .0001) and the presence of postoperative metatarsalgia (P < .0001). Receiver operating characteristic analysis revealed that the RML cut-off point was -3 mm for avoiding metatarsalgia, with an area under the curve of 0.88, a specificity of 88%, and a sensitivity of 85%. Preservation of relative first metatarsal length during first metatarsal osteotomy was important to prevent postoperative metatarsalgia. Level IV, retrospective case series. © The Author(s) 2016.

    Purpose This study examined the lifestyle and clinical risk factors for lymphedema in a cohort of patients who underwent bilateral breast cancer surgery. Patients and Methods Between 2013 and 2016, 327 patients who underwent bilateral breast cancer surgery were prospectively screened for arm lymphedema as quantified by the weight-adjusted volume change (WAC) formula. Arm perometry and subjective data were collected preoperatively and at regular intervals postoperatively. At the time of each measurement, patients completed a risk assessment survey that reported the number of blood draws, injections, blood pressure readings, trauma to the at-risk arm, and number of flights since the previous measurement. Generalized estimating equations were applied to ascertain the association among arm volume changes, clinical factors, and risk exposures. Results The cohort comprised 327 patients and 654 at-risk arms, with a median postoperative follow-up that ranged from 6.1 to 68.2 months. Of the 654 arms, 83 developed lymphedema, defined as a WAC ≥ 10% relative to baseline. On multivariable analysis, none of the lifestyle risk factors examined through the risk assessment survey were significantly associated with increased WAC. Multivariable analysis demonstrated that having a body mass index ≥ 25 kg/m(2) at the time of breast cancer diagnosis ( P = .0404), having undergone axillary lymph node dissection ( P = .0464), and receipt of adjuvant chemotherapy ( P = .0161) were significantly associated with increased arm volume. Conclusion Blood pressure readings, blood draws, injections, and number or duration of flights were not significantly associated with increases in arm volume in this cohort. These findings may help to guide patient education about lymphedema risk reduction strategies for those who undergo bilateral breast cancer surgery.

    Purpose. Age-related macular degeneration is the leading cause of blindness among the adult population in the developed world. To further the understanding of this disease, we have studied the genetically isolated Amish population of Ohio and Indiana. Methods. Cumulative genetic risk scores were calculated using the 19 known allelic associations. Exome sequencing was performed in three members of a small Amish family with AMD who lacked the common risk alleles in complement factor H (CFH) and ARMS2/HTRA1. Follow-up genotyping and association analysis was performed in a cohort of 973 Amish individuals, including 95 with self-reported AMD. Results. The cumulative genetic risk score analysis generated a mean genetic risk score of 1.12 (95% confidence interval [CI]: 1.10, 1.13) in the Amish controls and 1.18 (95% CI: 1.13, 1.22) in the Amish cases. This mean difference in genetic risk scores is statistically significant (P = 0.0042). Exome sequencing identified a rare variant (P503A) in CFH. Association analysis in the remainder of the Amish sample revealed that the P503A variant is significantly associated with AMD (P = 9.27 × 10−13). Variant P503A was absent when evaluated in a cohort of 791 elderly non-Amish controls, and 1456 non-Amish cases. Conclusions. Data from the cumulative genetic risk score analysis suggests that the variants reported by the AMDGene consortium account for a smaller genetic burden of disease in the Amish compared with the non-Amish Caucasian population. Using exome sequencing data, we identified a novel missense mutation that is shared among a densely affected nuclear Amish family and located in a gene that has been previously implicated in AMD risk.

    Quantifying associations in neuroscience (and many other scientific disciplines) is often challenged by high-dimensionality, nonlinearity and noisy observations. Many classic methods have either poor power or poor scalability on data sets of the same or different scales such as genetical, physiological and image data. Based on the framework of reproducing kernel Hilbert spaces we proposed a new nonlinear association criteria (NAC) with an efficient numerical algorithm and p-value approximation scheme. We also presented mathematical justification that links the proposed method to related methods such as kernel generalized variance, kernel canonical correlation analysis and Hilbert-Schmidt independence criteria. NAC allows the detection of association between arbitrary input domain as long as a characteristic kernel is defined. A MATLAB package was provided to facilitate applications. Extensive simulation examples and four real world neuroscience examples including functional MRI causality, Calcium imaging and imaging genetic studies on autism [Brain, 138(5):13821393 (2015)] and alcohol addiction [PNAS, 112(30):E4085-E4093 (2015)] are used to benchmark NAC. It demonstrates the superior performance over the existing procedures we tested and also yields biologically significant results for the real world examples. NAC beats its linear counterparts when nonlinearity is presented in the data. It also shows more robustness against different experimental setups compared with its nonlinear counterparts. In this work we presented a new and robust statistical approach NAC for measuring associations. It could serve as an interesting alternative to the existing methods for datasets where nonlinearity and other confounding factors are present. Copyright © 2016 Elsevier B.V. All rights reserved.

    Aromatase inhibitors (AIs) used as adjuvant therapy in postmenopausal women with hormone receptor-positive breast cancer cause diverse musculoskeletal side effects that include bone loss and its associated fracture. About half of the 391 patients treated with AIs in the Barcelona-Aromatase induced bone loss in early breast cancer cohort suffered a significant bone loss at lumbar spine (LS) and/or femoral neck (FN) after 2 years on AI-treatment. In contrast, up to one-third (19.6% LS, 38.6% FN) showed no decline or even increased bone density. The present study aimed to determine the genetic basis for this variability. SNPs in candidate genes involved in vitamin D and estrogen hormone-response pathways (CYP11A1, CYP17A1, HSD3B2, HSD17B3, CYP19A1, CYP2C19, CYP2C9, ESR1, DHCR7, GC, CYP2R1, CYP27B1, VDR and CYP24A1) were genotyped for association analysis with AI-related bone loss (AIBL). After multiple testing correction, 3 tag-SNPs (rs4077581, s11632698 and rs900798) located in the CYP11A1 gene were significantly associated (Pbone tissue and primary osteoblasts was demonstrated by RT-PCR. Both common isoforms of human cholesterol side-chain cleavage enzyme (encoded by CYP11A1 gene) were detected in osteoblasts by western blot. In conclusion, the genetic association of CYP11A1 gene with AIBL and its expression in bone tissue reveals a potential local function of this enzyme in bone metabolism regulation, offering a new vision of the steroidogenic ability of this tissue and new understanding of AI-induced bone loss. © 2015 Society for Endocrinology.

    In family psychology, the term flooding refers to the feeling of being overwhelmed by a family member's behavior in a manner that undermines an organized response. In the present investigation we first aimed to clarify the role of flooding in overreactive and lax discipline. The second study aim was to more fully establish the position of parental flooding in its nomological network given the relative paucity of research on parental flooding. Maternal discipline and physiological responses, as well as child behavior, were observed in laboratory discipline encounters with 97 mother-toddler dyads. Mothers then rated the extent to which they experienced flooding in response to their children's behavior and emotion displays during the immediately preceding discipline encounters. Mothers' experience of negative emotion was assessed via video-mediated recall. Flooding was positively associated with both overreactive and lax discipline; this association did not reflect confounding by mothers' experience of negative emotion. Flooding was further associated with mothers' experienced negative emotion and heart rate reactivity, as well as child misbehavior and negative emotion displays. The flooding-overreactive discipline association was concentrated in those mothers who exhibited greater increases in heart rate and greater vagal withdrawal, and whose children misbehaved more during the discipline encounter. The present results suggest the incremental validity of flooding in predicting discipline practices, as well as the strong fit of flooding in its nomological network. Parents' self-recognition of flooding may ultimately prove useful in parenting interventions as a signal to trigger compensatory techniques.

    Background & Aims Porphyria cutanea tarda (PCT) is the most common of the human porphyrias and results from an acquired deficiency of hepatic uroporphyrinogen decarboxylase (UROD). Some susceptibility factors have been identified; we examined associations among multiple factors in a large cohort of patients. Methods Multiple known or suspected susceptibility factors and demographic and clinical features of 143 patients (mean age 52 years, 66% male, 88% Caucasian) with documented PCT (mean onset at 41±8.8 yrs) were tabulated; associations were examined by contingency tables, classification and regression tree (CART) analysis and logistic regression. Results The most common susceptibility factors for PCT were ethanol use (87%), smoking (81%), chronic hepatitis C virus (HCV) infection (69%), and HFE mutations (53%; 6% C282Y/C282Y and 8% C282Y/H63D). Of those who underwent hepatic biopsy or ultrasound, 56% had evidence of hepatic steatosis. Of those with PCT, 66% of females took estrogen, 8% were diabetic, 13% had human immunodeficiency virus (HIV) infection, and 17% had inherited uroporphyrinogen decarboxylase (UROD) deficiency (determined by low erythrocyte UROD activity). HCV infection in patients with PCT was significantly associated with other behavior-related factors such as ethanol use (odds ratio [OR] 6.3) and smoking (OR 11.9). Conclusions Susceptibility factors for PCT were similar to previous studies; most patients had 3 or more. Associations between PCT and HCV, ethanol or smoking could be accounted for by a history of multiple substance abuse; other factors are distributed more randomly amongpatients. PMID:19948245

    Depressive disorders have been linked to health risk-related behaviours (HRBs) considered separately. Our objective was to study whether depression is associated with the co-occurrence of HRBs in adults. A sample of 17 355 subjects aged > or =18 years, derived from the 2002-03 cross-sectional Decennial Health Survey; probable depression was assessed with the CES-D scale. A cluster analysis of various HRBs (tobacco use, alcohol use, binge drinking, physical inactivity, certain eating habits) was used to study their co-occurrence. Multiple regressions adjusted on demographic and socio-economic characteristics, Body Mass Index and chronic illnesses were performed to study associations between probable depression and the HRBs clusters obtained. Five clusters were observed evidencing a gradient of cumulative exposure to HRBs: 'healthy lifestyles (Cluster 1), 'non-daily-consumers-fruit-and-green-vegetables' (Cluster 2), 'regular alcohol users' (Cluster 3), 'daily smokers' (Cluster 4) and 'cumulate risk takers' (Cluster 5). Compared with Cluster 1, positive associations were found between probable depression and Clusters 2, 4 and 5: OR 1.49 (95% CI 1.26-1.76) for Cluster 2; OR 1.81 (95% CI 1.54-2.12) for Cluster 4; OR 2.05 (95% CI 1.68-2.51) for Cluster 5. For Cluster 3, no association was found: OR 1.01 (95% CI 0.84-1.21). HRBs tend to co-occur in the general population, more frequently in case of probable depression. Further research is necessary to disentangle the direction of the links between depression and HRB clusters. Nonetheless, these results question the classic design of education campaigns considering HRBs separately. Moreover, screening for depression should be systematic during prevention consultations and various HRBs should be monitored when treating depressive patients.

    Office workers have a high prevalence of musculoskeletal conditions. This can be a significant economic burden due to health-related productivity loss. Individual and work-related factors related to office worker health-related productivity were investigated. A survey including the Health and Work Performance Questionnaire, which estimated productivity loss, also recorded individual and work-related factors with potential associations with health-related productivity. Muscle function and workstation ergonomics were examined through physical assessments. Linear models investigated the relationships between these factors and health-related productivity. Significant factors identified were occupational category (0.001 working as managers, with lower job satisfaction and psychological wellbeing, and those with musculoskeletal pain. Office worker health-related productivity loss is represented by a combination of both individual and work-related factors.

    Full Text Available Peanut (Arachis hypogaea consists of two subspecies, hypogaea and fastigiata, and has been cultivated worldwide for hundreds of years. Here, 158 peanut accessions were selected to dissect the molecular footprint of agronomic traits related to domestication using specific-locus amplified fragment sequencing (SLAF-seq method. Then, a total of 17,338 high-quality single nucleotide polymorphisms (SNPs in the whole peanut genome were revealed. Eleven agronomic traits in 158 peanut accessions were subsequently analyzed using genome-wide association studies (GWAS. Candidate genes responsible for corresponding traits were then analyzed in genomic regions surrounding the peak SNPs, and 1,429 genes were found within 200 kb windows centerd on GWAS-identified peak SNPs related to domestication. Highly differentiated genomic regions were observed between hypogaea and fastigiata accessions using FST values and sequence diversity (π ratios. Among the 1,429 genes, 662 were located on chromosome A3, suggesting the presence of major selective sweeps caused by artificial selection during long domestication. These findings provide a promising insight into the complicated genetic architecture of domestication-related traits in peanut, and reveal whole-genome SNP markers of beneficial candidate genes for marker-assisted selection (MAS in future breeding programs.

    This study aims to evaluate the influences of sleep duration and sleep variability (SleepV), upon adolescents' school-related situations. The Health Behaviour in School-Aged Children (HBSC) survey is based on a self-completed questionnaire. The participants were 3164 pupils (53.7% girls), attending the 8th and 10th grades, 14.9 years old, and were inquired about subjective sleep duration during the week and weekends, SleepV, fatigue, difficulties in sleep initiation, school achievement, feelings towards schools, pressure with school work and skipping classes. Multiple regression models used, as dependent variables: (a) school achievement, (b) disliking school, (c) pressure with school work and (d) skipping classes, using as independent variables, each of the remaining school-related variables, fatigue, total sleep duration and difficulties in sleep initiation. The average sleep duration in the week and during weekdays was lower than recommended for these age groups, and almost half of students had high SleepV between weekdays and weekends. A logistic model revealed that the absence of SleepV was associated with lower perception of school work pressure, less frequent skipping classes, more infrequent fatigue and more infrequent difficulties in sleep initiation. Poor sleep quality, SleepV and insufficient sleep duration affected negatively school-related variables. © 2015 International Union of Psychological Science.

    2015-01-01

    Cell phone use while driving (CPWD) has been shown to significantly reduce driver safety. This is a particular concern among young drivers who possess less driving experience and tend to engage in high rates of cell phone use. The present study identified psychological predictors of near accidents related to CPWD among a sample of 385 college student drivers. Participants answered a series of questions regarding their use of a cell phone while driving and completed measures of mindfulness, polychronicity, and intrusive thinking. Students who reported talking on their phone or texting more frequently while driving reported a higher incidence of near accidents related to each behavior. However, after controlling for CPWD, multiple regression analysis indicated that those who reported experiencing more cell phone-related intrusive thoughts also experienced more near accidents. Furthermore, two facets of mindfulness--acting with awareness and nonjudging of inner experience--were negatively associated with near accidents. These findings suggest that individuals who are more aware of the present moment and accepting of their affective responses may better regulate their attention while using a cell phone behind the wheel.

    2014-01-01

    Grounded in self-determination theory, obsessive passion for an activity has been associated with increased risky behaviour and rigid persistence, both symptomatic of dependence. However, it is unknown whether obsessive passion may predict the development of dependence, and furthermore, theoretically important relationships between basic need satisfaction, passion, exercise dependence and subsequent risky behaviour have not been fully explored. A sample of 100 professional dancers (50(fs); 50(ms); Mage = 20.88; SD = 2.69) completed self-ratings of risk-related behaviours (doctor visits; following treatment, and warming up), passion for dance and dance dependence. Findings supported the maladaptive nature of obsessive passion in relation to risky behaviour and as predicted dance dependence mediated this relationship. Interestingly, need satisfaction was positively related to both obsessive passion and harmonious passion. Results are discussed in the light of self-determination theory and dysfunctions of obsessive passion, suggesting that professional dancers are at risk of employing maladaptive behaviours if high in obsessive passion, which may be detectable via symptoms of dance dependence.

    Pregnant women who fear or experience HIV-related stigma may not get care for their own health or medications to reduce perinatal transmission of HIV. This study examined factors associated with anticipating and experiencing HIV-related stigma among 1777 pregnant women attending antenatal care clinics in rural Kenya. Women were interviewed at baseline, offered HIV testing and care, and a sub-set was re-interviewed at 4-8 weeks postpartum. Women who were older, had less education, whose husbands had other wives, and who perceived community discrimination against people with HIV had significantly greater adjusted odds of anticipating HIV stigma. Over half of the HIV-positive women interviewed postpartum reported having experienced stigma, much of which was self-stigma. Women experiencing minor depression, and those whose family knew of their HIV status had significantly greater adjusted odds of experiencing stigma. Lack of women's empowerment, as well as depression, may be important risk factors for HIV-related stigma and discrimination.

    Full Text Available Exposure to environmental chemicals, such as dioxin, is known to have adverse effects on the homeostasis of gonadal steroids, thereby potentially altering the sexual differentiation of the brain to express autistic traits. Dioxin-like chemicals act on the aryl hydrocarbon receptor (AhR, polymorphisms and mutations of AhR-related gene may exert pathological influences on sexual differentiation of the brain, causing autistic traits. To ascertain the relationship between AhR-related gene polymorphisms and autism susceptibility, we identified genotypes of them in patients and controls and determined whether there are different gene and genotype distributions between both groups. In addition, to clarify the relationships between the polymorphisms and the severity of autism, we compared the two genotypes of AhR-related genes (rs2066853, rs2228099 with the severity of autistic symptoms. Although no statistically significant difference was found between autism spectrum disorder (ASD patients and control individuals for the genotypic distribution of any of the polymorphisms studied herein, a significant difference in the total score of severity was observed in rs2228099 polymorphism, suggesting that the polymorphism modifies the severity of ASD symptoms but not ASD susceptibility. Moreover, we found that a significant difference in the social communication score of severity was observed. These results suggest that the rs2228099 polymorphism is possibly associated with the severity of social communication impairment among the diverse ASD symptoms.

    Background and aims Gambling disorder-related illegal acts (GDRIA) are often crucial events for gamblers and/or their entourage. This study was designed to determine the predictive factors of GDRIA. Methods Participants were 372 gamblers reporting at least three DSM-IV-TR (American Psychiatric Association, 2000) criteria. They were assessed on the basis of sociodemographic characteristics, gambling-related characteristics, their personality profile, and psychiatric comorbidities. A multiple logistic regression was performed to identify the relevant predictors of GDRIA and their relative contribution to the prediction of the presence of GDRIA. Results Multivariate analysis revealed a higher South Oaks Gambling Scale score, comorbid addictive disorders, and a lower level of income as GDRIA predictors. Discussion and conclusion An original finding of this study was that the comorbid addictive disorder effect might be mediated by a disinhibiting effect of stimulant substances on GDRIA. Further studies are necessary to replicate these results, especially in a longitudinal design, and to explore specific therapeutic interventions.

    The functions of the bronchus-associated lymphoid tissue (BALT) are under the control of the autonomic nervous system (sympathetic and parasympathetic nerve fibers). The relationships between the adrenergic nerve fibers and beta-adrenergic receptors were studied in the human BALT with the aim to demonstrate a probable neuromodulation. Morphological observations (staining with hematoxylin-eosin and scanning electron microscopy images) were carried out on samples of human BALT harvested during autopsies. Moreover, histochemical staining for norepinephrine (adrenaline = adrenergic nerve fibers) as well as for other catecholamines was performed. Finally, beta-adrenergic receptors were stained by means of a beta-blocking, radiolabeled drug (pindolol 125I). All our data were submitted to morphometric analysis (quantitative analysis of images and statistical analysis of data). Our results provide direct evidence of the presence and distribution of catecholaminergic nerve fibers and related beta-adrenergic receptors in BALT. beta-Adrenergic receptors are present above all in the most richly innervated part of the BALT, and are, therefore, in close relationship with their related adrenergic nerve fibers. Studies on the distribution of adrenergic neurotransmitters and related beta-adrenergic receptors in the human BALT are the first step for the demonstration of a probable neuromodulation of BALT.

    OBJECTIVE Arachnoid cysts (ACs) are congenital lesions bordered by an arachnoid membrane. Researchers have postulated that individuals with an AC demonstrate a higher rate of structural brain injury after trauma. Given the potential neurological consequences of a structural brain injury requiring neurosurgical intervention, the authors sought to perform a systematic review of sport-related structural-brain injury associated with ACs with a corresponding quantitative analysis. METHODS Titles and abstracts were searched systematically across the following databases: PubMed, Embase, CINAHL, and PsycINFO. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed case reports, case series, or observational studies that reported a structural brain injury due to a sport or recreational activity (hereafter referred to as sport-related) with an associated AC were included. Patients were excluded if they did not have an AC, suffered a concussion without structural brain injury, or sustained the injury during a non-sport-related activity (e.g., fall, motor vehicle collision). Descriptive statistical analysis and time to presentation data were summarized. Univariate logistic regression models to assess predictors of neurological deficit, open craniotomy, and cystoperitoneal shunt were completed. RESULTS After an initial search of 994 original articles, 52 studies were found that reported 65 cases of sport-related structural brain injury associated with an AC. The median age at presentation was 16 years (range 4-75 years). Headache was the most common presenting symptom (98%), followed by nausea and vomiting in 49%. Thirteen patients (21%) presented with a neurological deficit, most commonly hemiparesis. Open craniotomy was the most common form of treatment (49%). Bur holes and cyst fenestration were performed in 29 (45%) and 31 (48%) patients, respectively. Seven patients (11%) received

    The quality of life for breast cancer survivors has become increasingly important because of their high survival rate and prolonged life expectancy. The purpose of this study was to examine the association of physical activity following diagnosis and health-related quality of life (HRQOL) in breast cancer survivors. We conducted a cross-sectional study of breast cancer survivors. A total of 231 women aged 21-78 years who had been diagnosed with stages I to III breast cancer and had breast cancer surgery at least 6 months prior were recruited from three hospitals between September 2012 and April 2015 and were included in this study. We asked participants about their HRQOL and engagement in physical activity using structured questionnaires. We examined the association between HRQOL levels and physical activity using a generalized linear model. Breast cancer survivors in the high physical activity group (3rd tertile) were more likely to have lower scores for fatigue (p for trend = 0.001) and pain (p for trend = 0.02) and higher scores for sexual function (p for trend = 0.007) than those in the low physical activity group (1st tertile). When we stratified participants by stage, we found increasing scores for physical functioning (p for trend =0.01) and decreasing scores for fatigue (p for trend = 0.02) with increasing levels of physical activity in breast cancer survivors with stage I breast cancer. In survivors with stages II and III, we found statistically significant associations with fatigue (p for trend = 0.02) and sexual functioning (p for trend = 0.001). In conclusion, engagement in physical activity was related to better health-related quality of life among breast cancer survivors. Our findings may warrant further prospective and intervention studies to support the benefit of physical activity in improving the quality of life and survival of Korean breast cancer survivors.

    Obesity and osteoporosis share common physiological factors, including the presence of atherosclerosis, a risk factor for cardiometabolic disease, as well as a common progenitor that differentiates into both adipocytes and osteoblasts. Among the 23 polymorphisms associated with bone mineral density (BMD) in recent genome-wide association studies (GWASs), an Osterix polymorphism has been identified and associated with childhood obesity in girls. Therefore, we focused on elucidating polymorphisms associated with adulthood obesity in a sex-dependent manner among the previously published BMD-associated polymorphisms from GWASs. We performed 2 screenings of 18 BMD-associated polymorphisms for obesity-related traits in 2,362 adults aged >20 years. We excluded 13 polymorphisms showing deviations from Hardy-Weinberg equilibrium or no association with obesity-related traits (body mass index, waist circumference (WC), and waist-to-hip ratio). Among 5 selected polymorphisms (rs9594738 of RANKL, rs17066364 of NUFIP1, rs7227401 of OSBPL1A, and rs1856057 and rs2982573 of ESR1) analyzed, 2 polymorphisms (rs9594738 and rs17066364) were associated with obesity-related traits. We found sex-dependent associations such that the 4 polymorphisms (excluding rs9594738 of RANKL) were associated with abdominal traits such as WC and waist-to-hip ratio only in men. In addition, when the combined genetic risk score (GRS) for WC increase was calculated with 4 SNPs (rs9594738, rs17066364, rs7227401, and rs1856057) exhibiting similar trends for both sexes, the magnitude of the GRS effect for the WC increase was larger in men than in women (effect size = 0.856 cm, P = 0.0000452 for men; effect size = 0.598 cm, P = 0.00228 for women). In summary, we found 4 polymorphisms, previously related to osteoporosis, to be associated to obesity-related traits in a sex-dependent manner in Korean adults, particularly in men.

Among 5 selected polymorphisms (rs9594738 of RANKL, rs17066364 of NUFIP1, rs7227401 of OSBPL1A, and rs1856057 and rs2982573 of ESR1 analyzed, 2 polymorphisms (rs9594738 and rs17066364 were associated with obesity-related traits. We found sex-dependent associations such that the 4 polymorphisms (excluding rs9594738 of RANKL were associated with abdominal traits such as WC and waist-to-hip ratio only in men. In addition, when the combined genetic risk score (GRS for WC increase was calculated with 4 SNPs (rs9594738, rs17066364, rs7227401, and rs1856057 exhibiting similar trends for both sexes, the magnitude of the GRS effect for the WC increase was larger in men than in women (effect size = 0.856 cm, P = 0.0000452 for men; effect size = 0.598 cm, P = 0.00228 for women. In summary, we found 4 polymorphisms, previously related to osteoporosis, to be associated to obesity-related traits in a sex-dependent manner in Korean adults, particularly in men.

    Full Text Available The purpose of this study is to investigate how family-related opinions and stressful situations are related to psychological distress in women undergoing infertility treatment. The subjects in this cross-sectional study were recruited from female patients undergoing infertility treatment (n = 2540 at 70 infertility treatment institutions in Japan. Because of non-participation or missing data, the number of subjects included in the analysis was 635 (response rate, 25.0%. The family-related opinions and stressful situations were evaluated using the original questions. Psychological distress was assessed using a self-report measure, the Kessler Six-question Psychological Distress Scale (K6. The K6 scores of the following participants were significantly (p < 0.05 and independently high: those with more frequent miscarriage/stillbirth/abortions, those with repeated miscarriages as the cause of infertility, those with infertility of unknown causes, those living with no child, those having a low joint income with their partner, those with the opinion that “women should devote themselves to their household duties” those who had considered stopping treatment, those without the opinion that “married life without children is favorable” and those who had experienced stressful situations such as inadequate explanation by doctors, frustration of multiple failed attempts, differences of opinion with the partner, and lack of knowledge regarding when to stop treatment. Family-related opinions and stressful situations associated with psychological distress in women undergoing infertility treatment are outlined. The results of this study may contribute to the prevention of and care for psychological distress in female patients undergoing infertility treatment.

    Evidence consistently shows that diabetes is a risk factor for increased prevalence of gingivitis and periodontitis. But there is a controversy about the relationship between diabetes related factors and periodontal health. The aim of the present study is to explore the relationship between diabetes related factors such as glycosylated hemoglobin, fasting blood glucose, duration of diabetes and compliance to diabetes self management and periodontal health status. Periodontal health of 125 participants with type-2 diabetes mellitus was measured by the number of missing teeth, community periodontal index (CPI), Russell's periodontal index and papillary bleeding index. Information on sociodemographic factors, oral hygiene behavior, duration and compliance to self management of diabetes, levels of glycosylated hemoglobin(HbA1c) and fasting blood glucose(FBG) were collected by interview and hospital medical records. Statistically, independent t-test, an analysis of variance (ANOVA), chi-squared test and multiple regression analyses were used to assess the association between diabetes-related factors and periodontal health. Periodontal parameters including the number of missing teeth and papillary bleeding index were significantly influenced by duration of diabetes, FBG and compliance to self management of diabetes. CPI was significantly influenced by duration of diabetes, FBG and HbA1C. And Russell's periodontal index was significantly influenced by duration of diabetes, FBG, HbA1C and compliance to self management of diabetes. Results of multiple linear regression analysis showed that the duration of diabetes showed significant positive correlation with all of the periodontal health parameters, except for missing teeth. HbA1c was correlated with Russell's periodontal and papillary bleeding index. FBG and compliance to self management of diabetes were correlated with missing teeth and papillary bleeding index respectively. Diabetes-related factors such as duration of

    Insufficient data exist regarding the longitudinal influence of involuntary smoking on periodontitis progression. This study examined the relationship between involuntary smoking and periodontitis progression and the effects of involuntary smoking on salivary inflammatory and microbiologic markers related to periodontitis. Participants were recruited during annual health checkups in 2003 and 2005. In 2005, 200 of 273 (73%) Japanese employees examined at baseline underwent periodontal measurements, including clinical attachment level (CAL) and probing depth (PD). Periodontitis progression was identified when a subject displayed one or more teeth with an increase > or = 2.0 mm in CAL and PD during the 2 years. Salivary marker levels, including cotinine, were determined by enzyme assay, including enzyme-linked immunosorbent assay. The proportions of six periodontal pathogens in saliva were assessed using real-time polymerase chain reaction methodology. Based on receiver-operating characteristic analysis, non-, involuntary, and active smokers were defined as subjects exhibiting salivary cotinine levels of 0, 1 to 7, and > or = 8 ng/ml, respectively. By simple logistic regression analysis, age, alcohol consumption, smoking, breakfast habits, and working hours were related to the risk for significant periodontitis progression. Multiple logistic regression analysis revealed significantly higher periodontitis odds ratios (OR) in involuntary (OR = 2.23; 95% confidence interval [CI]: 1.03 to 4.83) and active (OR = 2.27; 95% CI: 1.02 to 5.04) smokers relative to non-smokers following adjustment for covariates. Levels of salivary markers, including albumin, aspartate aminotransferase, and lactoferrin, were significantly elevated in involuntary smokers relative to non-smokers. In contrast, the percentages of periodontal pathogens did not differ between the smoking groups, with the exception of Prevotella nigrescens, which displayed significantly lower levels in involuntary

    Clinical and experiments evidence indicate that protease inhibitors (PI) can cause bone mineral density (BMD) loss. However, the mechanism of such loss remains obscure. This single-center, cross-sectional study included 184 HIV-infected patients treated with PI who underwent dual-energy X-ray absorptiometry scan. Serum phosphorus, percentage of tubular reabsorption of phosphate (%TRP), thyroid and parathyroid function (iPTH), vitamin D, osteocalcin (OC), urinary deoxypyridinoline (DPD), and urinary cross-linked N-telopeptide of type I collagen (u-NTx) were measured. The rate of hypothyroidism in PI-users [32/117 (27%)] was double that in non-PI users [8/67 (12%), p = 0.016] and was significantly associated with PI use in multivariate analysis [odds ratio (OR) 11.37, 95% confidence interval (CI) 1.358-95.17, p = 0.025]. Spine BMD was significantly lower in hypothyroid patients than euthyroid, for both total population (-1.37 vs. -1.00, p = 0.041) and PI users (-1.56 vs. -1.13, p = 0.029). Multivariate regression analysis identified inverse correlation between hypothyroidism and spine BMD [estimate -0.437, 95% CI -0.858 to -0.024, p = 0.042]. OC, DPD and u-NTx were significantly higher in PI users than in non-PI users (p = 0.01, 0.05, and 0.01, respectively). PI use is associated with hypothyroidism as well as bone turnover acceleration, which worsens PI-associated BMD loss. In PI-treated patients, thyroid function tests are warranted to prevent further progression of PI-associated BMD loss.

    Sunbed use is associated with an increased risk for skin cancer and is particularly dangerous for younger persons. The objective of this study was to assess how demographic factors, health-related behaviours and appearance-related factors are associated with sunbed use. Cross-sectional data from the Danish National Youth Study collected by the National Institute of Public Health during 2014 was used. A total of 64,382 students aged 15-25years were included in the present study. Multilevel logistic regression analyses were used to determine associations. Sunbed use during the past 12months was reported by 22% of students, with a higher proportion among females (29%) than males (12%). Factors associated with sunbed use were older age, studying at a vocational college or a higher preparatory examination school compared to upper secondary school, and lower parental education. Furthermore, being a smoker, been binge-drinking, longer duration of exercise and been dieting were also associated with sunbed use. For females, poor dietary habits were also associated with sunbed use. Feeling overweight was associated with lower odds for sunbed use for males, but with higher odds for females. Lower body satisfaction was associated with higher odds of sunbed use, except for overweight males. Students who were underweight had lower odds for sunbed use, than normal weight students. Conclusively, we found evidence of associations between demographic factors, health-related behaviours and appearance-related factors and sunbed use. Understanding these relations could help to identify high-risk groups and guide preventive strategies for sunbed use and skin cancer prevention. Copyright © 2017 The Authors.

    Understanding the link between ethnicity and health is critical to making appropriate public policy decisions. Few population-level data are available about this connection, however, including the influence of ethnicity on the association between age-related macular degeneration (AMD) and vision-specific functioning (VSF). To identify the influence of ethnicity on VSF among Chinese, Malay, and Indian patients with AMD. This cross-sectional, population-based study relied on patients and their data from 3 population-based studies in 3 ethnic groups: Chinese, Malay and Indian. Of 10 033 Chinese, Malay, and Indian adults who participated in the study, 9962 (99.3%) who had gradable fundus images and Visual Function Index (VF-11) data available were included in the analyses for the present study. Uniocular presenting distance visual acuity was measured using the logMAR chart. Separate multiple linear regression models examined the association between AMD and VSF in the 3 ethnic groups, adjusting for age, sex, presenting visual acuity in the better-seeing eye, educational level, income, smoking status, hypertension, diabetes, cardiovascular disease, total cholesterol level, and other eye conditions. Data were collected between January 20, 2004, and December 19, 2011; data analysis was conducted between November 12, 2015, and December 28, 2016. Age-related macular degeneration according to fundus photographs graded using a modified Wisconsin Age-Related Maculopathy Grading System. Rasch analysis was used to convert VF-11 questionnaire scores to estimated interval measures of VSF. Of the 9962 participants, the mean (SD) age was 58.8 (10.4) years; 4909 (49.3%) were male; 590 (5.9%) had early AMD (241 Chinese, 161 Malays, and 188 Indians) and 60 (0.6%) had late AMD (25 Chinese, 21 Malays, and 14 Indians). In the adjusted models, compared with no AMD, early AMD was associated with a small reduction in VSF (2.9%; β = -0.12; 95% CI, -0.23 to -0.00; P = .046) in the

  1. Alcohol and Relatively Pure Cannabis Use, but Not Schizotypy, are Associated with Cognitive Attenuations

    Elevated schizotypy relates to similar cognitive attenuations as seen in psychosis and cannabis/polydrug use. Also, in schizotypal populations cannabis and polydrug (including licit drug) use are enhanced. These cognitive attenuations may therefore either be a behavioral marker of psychotic (-like) symptoms or the consequence of enhanced drug use in schizotypal populations. To elucidate this, we investigated the link between cognitive attenuation and cannabis use in largely pure cannabis users (35) and non-using controls (48), accounting for the potential additional influence of both schizotypy and licit drug use (alcohol, nicotine). Cognitive attenuations commonly seen in psychosis were associated with cannabis and alcohol use, but not schizotypy. Future studies should therefore consider (i) non-excessive licit substance use (e.g., alcohol) in studies investigating the effect of cannabis use on cognition and (ii) both enhanced illicit and licit substance use in studies investigating cognition in schizotypal populations.

    SUMMARY Age related macular degeneration (AMD) is the leading cause of irreversible blindness in the elderly population worldwide. While recent studies have demonstrated strong genetic associations of single nucleotide polymorphisms within a number of genes and AMD, other modes of regulation are also likely to play a role in its etiology. We identified a significantly decreased level of methylation on the IL17RC promoter in AMD patients. Further, we showed that hypomethylation of the IL17RC promoter in AMD patients led to an elevated expression of its protein and mRNA in peripheral blood as well as in the affected retina and choroid, suggesting that the DNA methylation pattern and expression of IL17RC may potentially serve as a biomarker for the diagnosis of AMD and likely plays a role in disease pathogenesis.

    Twenty-three patients admitted with acute psychosis who were cannabis positive on urinary screening were each matched, with respect to sex, with two psychotic controls who screened negatively for all substances. The lifetime morbid risk of psychiatric disorder was estimated among the first degree relatives of cases and controls, using RDC-FH criteria to define diagnoses, and Weinberg's shorter method of age correction. The cases had a significantly greater familial morbid risk of schizophrenia (7.1%) than the controls (0.7%), while the risks of other psychoses, and of non-psychotic conditions were similar. The same pattern of familial risk was evident when the analysis was restricted to patients with DSM-III schizophrenia. The data suggest that the development or recurrence of acute psychosis in the context of cannabis use may be associated with a genetic predisposition to schizophrenia.

    Full Text Available AIM: To investigate the association between SERPING1 rs2511989 (G>A polymorphism and age-related macular degeneration (AMD. METHODS: A number of electronic databases (up to July 15, 2014 were searched independently by two investigators. A Meta-analysis was performed on the association between SERPING1 rs2511989 polymorphism and AMD. Pooled odds ratios (ORs with 95% confidence intervals (CIs were estimated. RESULTS: Eight studies with 16 cohorts consisting of 9163 cases and 6813 controls were included in this Meta-analysis. There was no significant association between rs2511989 polymorphism and AMD under all genetic models in overall estimates (A vs G: OR= 0.938, 95%CI =0.858-1.025; AA vs GG:OR =0.871, 95%CI =0.719-1.056; AG vs GG: OR =0.944, 95%CI =0.845-1.054; AA+AG vs GG: OR =0.927, 95% CI =0.823-1.044; AA vs AG+GG: OR =0.890, 95%CI =0.780-1.034. Cumulative Meta-analyses also showed a trend of no association between rs2511989 polymorphism and AMD as information accumulated by year. Subgroup analysis and Meta-regression analysis indicated that age-matching status was the main source of heterogeneity. Sensitivity analysis found the results in overall comparisons and subgroup comparisons of white subjects under the allele model were found to have significantly statistical differences after studies deviating from Hardy-Weinberg equilibrium (HWE were excluded (overall: OR=0.918, 95%CI = 0.844-0.999, P =0.049; whites: OR =0.901, 95%CI = 0.817-0.994, P =0.038. However, the results were not sufficiently robust for further sensitivity analysis and statistical differences disappeared on applying Bonferroni correction (with a significance level set at 0.05/25. CONCLUSION: This Meta-analysis indicates that SERPING1 rs2511989 polymorphism and AMD tend to have no association with each other. Age matching status is a big confounding factor, and more studies with subtle designs are warranted in future.

    Full Text Available OBJECTIVE: To investigate possible correlations between apelin-12 levels and obesity in children in China and associations between apelin-12 and obesity-related markers, including lipids, insulin sensitivity and insulin resistance index (HOMA-IR. METHODS: Forty-eight obese and forty non-obese age- and gender-matched Chinese children were enrolled between June 2008 and June 2009. Mean age was 10.42 ± 2.03 and 10.86±2.23 years in obesity and control groups, respectively. Main outcome measures were apelin-12, BMI, lipids, glucose and insulin. HOMA-IR was calculated for all subjects. RESULTS: All obesity group subjects had significantly higher total cholesterol (TC, triglycerides (TG, low-density lipoprotein cholesterol (LDL-C, insulin levels and HOMA-IR (all P<0.05. In separate analyses, obese girls had significantly higher LDL-C, insulin and HOMA-IR than controls, and obese boys had significantly higher TC, TG, insulin and HOMA-IR than controls (all P<0.05. Apelin-12 levels were significantly higher in obese girls compared to controls (P = 0.024, and correlated positively with TG in all obese subjects. Among obese girls, apelin-12 levels correlated positively with TG, insulin and HOMA-IR after adjusting for age and BMI. In all boys (obese and controls apelin-12 was positively associated with fasting plasma glucose (FPG. No significant correlations were found in either group between apelin-12 levels and other characteristics after adjusting for age, sex, and BMI. CONCLUSIONS: Apelin-12 levels are significantly higher in obese vs. non-obese girls in China and correlate significantly with obesity-related markers insulin, HOMA-IR, and TG. Increased apelin-12 levels may be involved in the pathological mechanism of childhood obesity.

    Impulse control disorders (ICDs) in Parkinson's disease (PD) are related to treatment with dopamine agonists, which is thought to deregulate the dopaminergic mesolimbic pathway and impair reward evaluation. EEG studies in healthy controls (HCs) have suggested that the increase in theta power observed after negative outcome is a marker of reward processing. To compare outcome-locked, event-related spectral perturbation in a gambling task in PD patients with and without ICDs and in HCs. Twelve PD patients with ICDs, 12 PD patients without ICDs and 14 HCs underwent EEG while performing a gambling task. The groups were compared in terms of (i) the peak EEG power in the theta (4-7 Hz), alpha (8-14 Hz) and beta (15-30 Hz) frequency bands between 200 and 500 ms after the outcome, and (ii) time-frequency plots at Fz, FCz and Cz. Positive outcomes were associated with greater theta power than negative outcomes in patients without ICDs and in HCs, but not in patients with ICDs. Patients with ICDs and HCs displayed greater theta power following unexpectedly high outcomes. HCs displayed greater beta power following high amplitude than low amplitude outcomes, whereas patients with ICD showed the opposite pattern. In PD, ICDs are associated with (i) weaker modulation of frontocentral theta power by reward valence, (ii) greater frontocentral theta power following unexpected, high outcomes, and (iii) a reversal of the effect of risk on beta oscillations. These observations are consistent with an impairment in prediction error computation in the medial prefrontal cortex.

    Coexistent primary biliary cirrhosis (PBC) and coeliac disease has been recorded but the association has not been systematically studied. To determine relative prevalences of PBC and coeliac disease in a defined population over a 12 year period. All patients with PBC or coeliac disease in a stable population of 250,000 in South Wales were identified from a clinical register and laboratory records. Sixty seven patients with PBC and 143 patients with coeliac disease have been diagnosed and followed over a median of 86 (4-135) months; point prevalences in 1996 were 20 per 100,000 for PBC and 54 per 100,000 for coeliac disease. PBC in patients with coeliac disease was sought by investigating abnormal liver function tests. Ten (7%) had persistent abnormalities and three had PBC. Coeliac disease in patients with PBC was sought by investigating malabsorption, haematinic deficiency, positive antigliadin antibody, or coeliac disease family history. Eleven patients underwent duodenal biopsy revealing one further coeliac disease case. Four patients (three women have both conditions giving a point prevalence for patients with both conditions of 1.6 per 100,000 (95% confidence limits 0.44 to 4.1 per 100,000). Prevalence of PBC in patients with coeliac disease was 3% and of coeliac disease in patients with PBC was 6%. A 12 year study of a stable 250,000 population revealed a relative prevalence of PBC in 3% of 143 patients with coeliac disease and of coeliac disease in 6% of 67 patients with PBC. PBC and coeliac disease are therefore associated. Screening for PBC in patients with coeliac disease using antimitochondrial antibody testing and screening for coeliac disease in patients with PBC with antigliadin antibody testing or duodenal biopsy are recommended.

    Licensed premises are associated with a considerable level of alcohol-related harm. This study examined the effectiveness of an educational policing strategy, implemented as routine policing practice, to reduce the number of patrons of licensed premises involved in police-recorded incidents of violence, disorder and motor vehicle crashes. The educational policing strategy targeted on-licensed premises registered as operating in 2003. The strategy was delivered by police and was overseen by the research team. The intervention was conducted in 21 non-metropolitan New South Wales Police Force commands. On the basis of routinely collected and recorded police data, premises received one of three levels of police response on three separate occasions from December 2002 to July 2003. The police responses were letters, incident reports, covert audits and feedback meetings. The rate of patrons who had last consumed alcohol on licensed premises before being involved in police-recorded incidents decreased from 1.24 per premises in the 4-month baseline period to 1.11 in the 4-month follow-up period (p=0.08). There was a significant reduction, from 7.08 to 5.65 patrons (p=0.03), in such a rate for high-risk premises that received the most intensive police response. High-risk premises also recorded a significant reduction in the rate of intoxicated patrons involved in such incidents, from 5.50 to 4.40 (p=0.05). The findings suggest a potential benefit of an educational policing strategy in reducing alcohol-related harm associated with licensed premises. Further implementation of this strategy concurrent with rigorous evaluation is warranted.

    Full Text Available We investigated the association between pulse wave velocity (PWV and HIV infection, antiretroviral treatment-related characteristics, viral load, immune status, and metabolic changes in a cross-sectional study nested in a cohort of HIV/AIDS patients who have been followed for metabolic and cardiovascular changes since 2007. The study included patients recruited from the cohort (N = 261 and a comparison group (N = 82 of uninfected individuals, all enrolled from April to November 2009. Aortic stiffness was estimated using the carotid-femoral PWV (Complior-Artech, Paris, France. The groups were similar with respect to age, metabolic syndrome, diabetes mellitus, Framingham score, and use of antihypertensive and hypolipidemic medications. Hypertension was more frequent among the controls. Individuals with HIV had higher triglyceride, glucose and HDL cholesterol levels. Among individuals with HIV/AIDS, those with a nadir CD4+ T-cell count <200 cells/mm³ had a higher PWV (P = 0.01. There was no statistically significant difference when subjects were stratified by gender. Heart rate, age, male gender, and blood pressure were independently correlated with PWV. Nadir CD4+ T-cell count did not remain in the final model. There was no significance difference in PWV between HIV-infected individuals and uninfected controls. PWV was correlated with age, gender, and blood pressure across the entire population and among those infected with HIV. We recommend cohort studies to further explore the association between inflammation related to HIV infection and/or immune reconstitution and antiretroviral use and PWV.

    The association of the xenotropic murine leukemia virus-related virus (XMRV) with prostate cancer continues to receive heightened attention as studies report discrepant XMRV prevalences ranging from zero up to 23%. It is unclear if differences in the diagnostic testing, disease severity, geography, or other factors account for the discordant results. We report here the prevalence of XMRV in a population with well-defined prostate cancers and RNase L polymorphism. We used broadly reactive PCR and Western blot (WB) assays to detect infection with XMRV and related murine leukemia viruses (MLV). We studied specimens from 162 US patients diagnosed with prostate cancer with a intermediate to advanced stage (Gleason Scores of 5-10; moderate (46%) poorly differentiated tumors (54%)). Prostate tissue DNA was tested by PCR assays that detect XMRV and MLV variants. To exclude contamination with mouse DNA, we also designed and used a mouse-specific DNA PCR test. Detailed phylogenetic analysis was used to infer evolutionary relationships. RNase L typing showed that 9.3% were homozygous (QQ) for the R462Q RNase L mutation, while 45.6% and 45.1% were homozygous or heterozygous, respectively. Serologic testing was performed by a WB test. Three of 162 (1.9%) prostate tissue DNA were PCR-positive for XMRV and had undetectable mouse DNA. None was homozygous for the QQ mutation. Plasma from all three persons was negative for viral RNA by RT-PCR. All 162 patients were WB negative. Phylogenetic analysis inferred a distinct XMRV. We found a very low prevalence of XMRV in prostate cancer patients. Infection was confirmed by phylogenetic analysis and absence of contaminating mouse DNA. The finding of undetectable antibodies and viremia in all three patients may reflect latent infection. Our results do not support an association of XMRV or MLV variants with prostate cancer.

    Full Text Available Abstract Background MicroRNAs are important regulators of transcription in hematopoiesis. Their expression deregulations were described in association with pathogenesis of some hematological malignancies. This study provides integrated microRNA expression profiling at different phases of chronic myeloid leukemia (CML with the aim to identify microRNAs associated with CML pathogenesis. The functions of in silico filtered targets are in this report annotated and discussed in relation to CML pathogenesis. Results Using microarrays we identified differential expression profiles of 49 miRNAs in CML patients at diagnosis, in hematological relapse, therapy failure, blast crisis and major molecular response. The expression deregulation of miR-150, miR-20a, miR-17, miR-19a, miR-103, miR-144, miR-155, miR-181a, miR-221 and miR-222 in CML was confirmed by real-time quantitative PCR. In silico analyses identified targeted genes of these miRNAs encoding proteins that are involved in cell cycle and growth regulation as well as several key signaling pathways such as of mitogen activated kinase-like protein (MAPK, epidermal growth factor receptor (EGFR, ERBB, transforming growth factor beta (TGFB1 and tumor protein p53 that are all related to CML. Decreased levels of miR-150 were detected in patients at diagnosis, in blast crisis and 67% of hematological relapses and showed significant negative correlation with miR-150 proved target MYB and with BCR-ABL transcript level. Conclusions This study uncovers microRNAs that are potentially involved in CML and the annotated functions of in silico filtered targets of selected miRNAs outline mechanisms whereby microRNAs may be involved in CML pathogenesis.

    Full Text Available The aim of this study was to detect positional candidate genes located within the support interval (SI regions based on the results of red blood cell, mean corpuscular volume (MCV, and mean corpuscular hemoglobin quantitative trait locus (QTL in Sus scrofa chromosome 13, and to verify the correlation between specific single-nucleotide polymorphisms (SNPs located in the exonic region of the positional candidate gene and the three genetic traits. The flanking markers of the three QTL SI regions are SW38 and S0215. Within the QTL SI regions, 44 genes were located, and runt-related transcription factor 1, dual-specificity tyrosine-(Y-phosphorylation regulated kinase 1A (DYRK1A, and potassium inwardly-rectifying channel, subfamily J, member 15 KCNJ15–which are reported to be related to the hematological traits and clinical features of Down syndrome–were selected as positional candidate genes. The ten SNPs located in the exonic region of the three genes were detected by next generation sequencing. A total of 1,232 pigs of an F2 resource population between Landrace and Korean native pigs were genotyped. To investigate the effects of the three genes on each genotype, a mixed-effect model which is the considering family structure model was used to evaluate the associations between the SNPs and three genetic traits in the F2 intercross population. Among them, the MCV level was highly significant (nominal p = 9.8×10−9 in association with the DYRK1A-SNP1 (c.2989 G

    To examine the relationship between dark adaptation (DA) and optical coherence tomography (OCT)-based macular morphology in age-related macular degeneration (AMD). Prospective, cross-sectional study. Patients with AMD and a comparison group (>50 years) without any vitreoretinal disease. All participants were imaged with spectral-domain OCT and color fundus photographs, and then staged for AMD (Age-related Eye Disease Study system). Both eyes were tested with the AdaptDx (MacuLogix, Middletown, PA) DA extended protocol (20 minutes). A software program was developed to map the DA testing spot (2° circle, 5° superior to the fovea) to the OCT B-scans. Two independent graders evaluated the B-scans within this testing spot, as well as the entire macula, recording the presence of several AMD-associated abnormalities. Multilevel mixed-effects models (accounting for correlated outcomes between 2 eyes) were used for analyses. The primary outcome was rod-intercept time (RIT), defined in minutes, as a continuous variable. For subjects unable to reach RIT within the 20 minutes of testing, the value of 20 was assigned. We included 137 eyes (n = 77 subjects), 72.3% (n = 99 eyes) with AMD and the remainder belonging to the comparison group. Multivariable analysis revealed that even after adjusting for age and AMD stage, the presence of any abnormalities within the DA testing spot (ß = 4.8, P dark-adapt. Subretinal drusenoid deposits and ellipsoid zone changes seem to be strongly associated with impaired dark adaptation. Copyright © 2017 American Academy of Ophthalmology. Published by Elsevier Inc.

    Full Text Available Genetic and environmental factors affect the pathogenesis of Parkinson's disease (PD. Genetic variants of the enzyme glutathione S-transferases (GST may be related to the disease. This study aimed to evaluate the influence of genetic variants of GST (GSTT1/GSTM1 and their association with the exposure to environmental toxins in PD patients. We studied 254 patients with PD and 169 controls. The GSTM1/GSTT1 variants were analyzed by polymerase chain reaction. We applied the Fisher's exact test and the χ2 test for statistical analysis (p<0.05. The present and absence for GSTT1 and GSTM1 were similar in patients and controls. The null for GSTT1 and GSTM1 (0/0 and exposure to pesticides prevailed in patients (18% compared to controls (13%, p=0.014. This study suggests the association between PD and previous exposure to pesticides, whose effect may be enhanced in combination with null for GSTT1/GSTM1.

    Full Text Available Objective: To analyze variables associated with recurrence of blood alcohol content (BAC-related traffic violations among drivers in southern Brazil. Method: This cross-sectional study included 12,204 driving-under-the-influence (DUI offenders according to data provided by the Rio Grande do Sul state Transportation Department. Sociodemographic characteristics, license duration, license category, and psychological assessment results were analyzed. Drivers convicted of DUI more than once in 2009/2010 were considered recidivists. Variables were evaluated using descriptive statistical analysis and Poisson regression, adjusted by sex, age, and education level. Results: A total of 538 (4.41% drivers were considered recidivists. The following variables showed the strongest associations with recidivism: being aged 41-50 years (prevalence ratio [PR] = 3.41, being licensed for ≥ 12 years (PR = 1.86, being licensed for motorcycles, cars and trucks (PR = 1.36, having a license with psychological restrictions (PR = 1.33, and driving a truck or a similar vehicle at the moment of notification (PR = 1.08. Conclusions: In the age group with the highest risk for recurrence, drivers showed a higher probability of having a diagnosis of alcohol dependence and other psychiatric comorbidities that hinder the control of alcohol use. Psychological assessments seem to be important in predicting repeat offenses, especially when limited aptitudes are suspected, and should therefore be better investigated.

    Age-related hearing impairment (ARHI), or presbycusis, is a common condition of the elderly that results in significant communication difficulties in daily life. Clinically, it has been defined as a progressive loss of sensitivity to sound, starting at the high frequencies, inability to understand speech, lengthening of the minimum discernable temporal gap in sounds, and a decrease in the ability to filter out background noise. The causes of presbycusis are likely a combination of environmental and genetic factors. Previous research into the genetics of presbycusis has focused solely on hearing as measured by pure-tone thresholds. A few loci have been identified, based on a best ear pure-tone average phenotype, as having a likely role in susceptibility to this type of hearing loss; and GRM7 is the only gene that has achieved genome-wide significance. We examined the association of GRM7 variants identified from the previous study, which used an European cohort with Z-scores based on pure-tone thresholds, in a European–American population from Rochester, NY (N = 687), and used novel phenotypes of presbycusis. In the present study mixed modeling analyses were used to explore the relationship of GRM7 haplotype and SNP genotypes with various measures of auditory perception. Here we show that GRM7 alleles are associated primarily with peripheral measures of hearing loss, and particularly with speech detection in older adults. PMID:23102807

    Lung function is an important indicator of cystic fibrosis disease status and those with better forced expiratory volume in 1 s (FEV(1))% predicted have tended to report a better health-related quality of life (HRQoL) in cross-sectional studies. The relationship between lung function and HRQoL over time is unknown. This work assesses the natural progression of HRQoL reporting over many years and compares assessments across a whole decade and evaluates the relationship between lung function and HRQoL longitudinally. Demographic (age, gender), clinical (FEV(1)% predicted, body mass index, diabetes, Burkholderia cepacia complex, intravenous access device and nutritional status) and HRQoL (Cystic Fibrosis Quality of Life Questionnaire) variables were obtained every 2 years over a 12-year period (seven time points from 1998 to 2010). HRQoL and lung function declined slowly over time and significant decade changes were observed for FEV(1)% predicted and the nine domains of the Cystic Fibrosis Quality of Life Questionnaire. The results of random coefficient modelling indicated that, at the population level, decreasing FEV(1)% predicted was associated with decreasing HRQoL after adjusting for confounding variables. However, the percentage of patients for whom a decrease in lung function was associated with a decrease in HRQoL differed according to the quality of life domain. HRQoL and FEV(1)% predicted decline slowly; nevertheless, a decrease in lung function predicted a decrease in HRQoL over time.
