    Full Text Available Continual data checking is considered as one of the most common search tools for frequent itemsets which requires storage on memory. On the other hand, according to properties of data stream which are unlimited productions with a high-speed, it is not possible saving these data on memory and we need for techniques which enables online processing and finding repetitive standards. One of the most popular techniques in this case is using sliding windows. The benefits of these windows can be reducing memory usage and also search acceleration. In this article, a new vertical display and an algorithm is provided based on the pins in order to find frequent itemsets in data streams. Since this new display has a compressed format itself so, the proposed algorithm in terms of memory consumption and processing is more efficient than any other similar algorithms.

    Full Text Available Abstract Background To describe the characteristics of emergency department (ED patients defined as frequent presenters (FP presenting to an Australian emergency department network and compare these with a cohort of non-frequent presenters (NFP. Method A retrospective chart review utilising an electronic emergency medicine patient medical record database was performed on patients presenting to Southern Health EDs from March 2009 to March 2010. Non-frequent presenters were defined as patients presenting less than 5 times and frequent presenters as presenting 8 or more times in the study period. Characteristics of both groups were described and compared. Results During the 12-month study period there were 540 FP patients with 4549 admissions and 73,089 NFP patients with 100,943 admissions. FP patients were slightly older with a significant increase in frequency of patients between the ages of 70 to 79 years and they were more likely to be divorced or separated than NFP patients. Frequent presenters to the emergency department were more likely to utilise the ambulance service to arrive at the hospital, or in the custody of police than NFP patients. FPs were more likely to be admitted to hospital, more likely to have an admission to a mental health bed than NFP patients and more likely to self-discharge from the emergency department while waiting for care. Conclusions There are major implications for the utilisation of limited ED resources by frequent presenters. By further understanding the characteristics of FP we may be able to address the specific health care needs of this population in more efficient and cost effective ways. Further research analysing the effectiveness of targeted multidisciplinary interventions aiming to reduce the frequency of ED attendances may be warranted.

  3. Genitourinary tuberculosis - a rare presentation of a still frequent infection in renal transplant recipients

    Full Text Available Abstract Mycobacterium tuberculosis infection in renal transplant recipients is associated with significant morbidity and mortality. Genitourinary tuberculosis is a less frequent presentation and a high level of suspicion is needed to avoid treatment delay. Management is challenging due to the interaction of calcineurin inhibitors with antituberculous medications and the known side effects of these drugs, with higher prevalence in this population. The authors present a case of a renal transplant recipient with urinary and constitutional symptoms whom is diagnosed with tuberculosis after a prostatic biopsy in an already disseminated stage and develops hepatotoxicity to antituberculous therapy.

    In recent years we have observed with increasing frequency granulomatous papular lesions involving the knees, for which we proposed the term papular sarcoidosis of knees. To evaluate the clinicopathological features of papular sarcoidosis of the knees. Patients with papular lesions of the knees and histopathologically sarcoid granulomas were included in the study. Systemic sarcoidosis was investigated in all cases. Clinical charts were retrospectively retrieved. Biopsy specimens were evaluated under polarized light to detect foreign bodies. Fifty-three patients fulfilled inclusion criteria. In 36 cases systemic sarcoidosis was diagnosed and these cases were considered as papular sarcoidosis of the knees. Foreign particles were observed in 21 of these 36 patients. In only 9/36 patients did the activity of systemic disease persist over two years. In 17 cases sarcoidosis could not be demonstrated during follow-up. Papular sarcoidosis of the knees can be considered a relatively frequent form of cutaneous sarcoidosis usually present at the beginning of the disease that can be useful for the diagnosis of sarcoidosis. It is mainly observed in acute forms of sarcoidosis and can be considered a sign of good prognosis.

    Full Text Available Central sulcus hemorrhage is a rare imaging finding that can be related to cerebral amyloidosis in a normotensive non-traumatic elderly patient and present as an isolated finding or in association with other areas of involvement. We report a case presenting with an isolated central sulcus hemorrhage on computed tomography. Further imaging work-up excluded other potential causes of peripheral hemorrhages and established a putative diagnosis of cerebral amyloidosis.

    Nocturnal awakening is the most frequent insomnia complaint in the general population. In contrast to a growing knowledge based on adults, little is known about its prevalence, correlated factors, and associations with subjective sleep perception and daytime sleepiness in children. This study was designed to assess the prevalence and the correlate factors of frequent nocturnal awakening (FNA) among Chinese school-aged children. Furthermore, the associations of FNA with subjective sleep perception and daytime sleepiness were examined. A random sample of 20,505 children aged 5.00 to 11.92 years old (boys: 49.5% vs. girls: 50.5%) participated in a cross-sectional survey, which was conducted in eight cities of China. Parent-administered questionnaires were used to collect information on children's sleep behaviors, sleep perception, and potential influential factors of FNA from six domains. Univariate and multivariate logistic regression models were performed. The prevalence of FNA was 9.8% (10.0% for boys vs. 8.9% for girls) in our sampled children. The prominent FNA-related factors inclued biological health problems, such as overweight/obesity (OR = 1.70), chronic pain during night (OR = 2.47), and chronic respiratory condition (OR = 1.23), poor psychosocial condition, such as poor mental and emotional functioning (OR = 1.34), poor sleep hygiene, such as frequently doing exciting activities before bedtime (OR = 1.24) and bedtime resistance (OR = 1.42), and parents' history of insomnia (OR = 1.31). FNA was associated with subjective poor sleep quality (OR = 1.24), subjective insufficient sleep (OR = 1.21), and daytime sleepiness (OR = 1.35). FNA was associated with poor sleep and daytime sleepiness. Compared to sleep environment and family susceptibility, chronic health problems, poor psychosocial condition, and poor sleep hygiene had greater impact on FNA, indicating childhood FNA could be partly prevented by health promotion, by psychological intervention, and by

    Specific food-dependent exercise-induced anaphylaxis (S-FDEIAn) is a distinct form of food allergy in which symptoms are elicited by exercise performed after ingesting food to which the patient has become sensitised. Non-specific FDEIAn (NS-FDEIAn) is a syndrome provoked by exercise performed after ingesting any food. We sought to identify the culprit allergenic molecules in patients with FDEIAn, combining 'classic' allergy testing with an allergenic molecule-based microarray approach for IgE detection. All subjects were evaluated who reported at least one episode of anaphylaxis in association with physical exercise performed within 4 h after a meal. We performed skin prick tests (SPT) with commercial food extracts, prick plus prick tests (P + P) with fresh foods (P + P), and serum specific IgE assays by means of both the ImmunoCAP (CAP) and the ISAC 89 microarray system (ISAC). Among our 82 FDEIAn patients, the most frequent suspected foods were tomato, cereals, and peanut. SPT, P + P, and CAP displayed different degrees of sensitivity. Each test disclosed some positivities not discovered by others. Seventy-nine subjects were positive to at least one food (49 to more than 20), whereas three were negative. All suspected foods were positive to at least one of SPT, P + P, and CAP. When tested using the ISAC, 64 (78%) subjects were positive to Pru p 3 [peach lipid transfer protein (LTP)], 13 were positive to other food allergen molecules, and five displayed negative results to all food allergenic molecules. Overall, 79 patients probably had S-FDEIAn and the other 3 NS-FDEIAn. Multiple food hypersensitivity represents a clinical hallmark of a large percentage of FDEIAn patients. The very high prevalence of IgE to the LTP suggests a role of this allergen group in causing S-FDEIAn. © 2012 Blackwell Publishing Ltd.

    Among phenomena involving the subjective present, duration perception is especially worth discussing from the viewpoints of psychophysics, cognitive neuroscience, and computational modeling of underlying mechanisms. First, several situations in which moving visual stimuli appear to last longer are reported. Second, the phenomenon of illusory time compression, which occurs in a moving stimulus after prolonged observation of another stimulus moving at a faster speed, is described. Third, how an attended visual stimulus appears to last longer and how a stimulus appears to last for a shorter duration when attention is directed away are explained. Finally, possible underlying mechanisms in relation to the stages of hierarchical visual information processing are discussed.

    Background The chronic use of antifungal agents in the treatment of fungal infection in general and oropharyngeal candidiasis mainly in AIDS patient’s leads to the selection of strain resistant to these therapies and a shift in the spectrum of Candida species. This study determines the species diversity and in vitro susceptibility of Candida isolates from late presenting AIDS patients in northwest Ethiopia. Methods Two hundred and twenty one HIV/AIDS patients were assessed with a standardized evaluation form at enrolment. Oral rinses were cultured on CHROMagar plates at 37°C for 48 hours and Candida species identification were made following standard microbiological techniques. In vitro drug susceptibility tests were made using broth microdilution method. Results The colonization rate of Candida species was found to be 82.3% (177/215). C. albicans was the predominant species isolated from 139 (81%) patients but there was a diversity of other species. C. glabrata was the most frequent non-albicans species isolated in 22.5% (40/177) of the patients followed by C. tropicalis 14.1% (27/177), C. krusei 5.6% (10) and other unidentifiable Candida species 4% (7/177). Recurrent episodes of oropharyngeal candidiasis and previous exposure to antifungal drugs were found to be predisposing factors for colonization by non-albicans species. Irrespective of the Candida species identified 12.2% (11/90), 7.7% (7/90) and 4.7% (4) of the isolates were resistant to fluconazole, ketoconazole and itraconazole, respectively. In contrast, resistance to micafungin, amphotericin B and 5-Fluorocytosine was infrequent. Conclusion HIV/AIDS patients are orally colonized by single or multiple albicans and non- albicans Candida species that are frequently resistant to azoles and occasionally to amphotericin B, 5-Fluorocytosine and micafungin. These highlight the need for national surveillance for examining Candida epidemiology and resistance to antifungal drugs. PMID:23398783

    The aim of this study was to describe the differences in the presence of myofascial trigger points (TrPs) in the upper trapezius,sternocleidomastoid, levator scapulae and suboccipital muscles between patients presenting with mechanical neck pain and control healthy subjects. Twenty subjects with mechanical neck pain and 20 matched healthy controls participated in this study. TrPs were identified, by an assessor blinded to the subjects' condition, when there was a hypersensible tender spot in a palpable taut band, local twitch response elicited by the snapping palpation of the taut band, and reproduction of the referred pain typical of each TrP. The mean number of TrPs present on each neck pain patient was 4.3 (SD: 0.9), of which 2.5 (SD: 1.3) were latent and 1.8 (SD: 0.8) were active TrPs. Control subjects also exhibited TrPs (mean: 2; SD: 0.8). All were latent TrPs. Differences in the number of TrPs between both study groups were significant for active TrPs (P latent TrPs (P > 0.5). Moreover, differences in the distribution of TrPs within the analysed cervical muscles were also significant (P Active TrPs were more frequent in patients presenting with mechanical neck pain than in healthy subjects. ©2006 Elsevier Ltd.

    Abnormal arousal processes, sympathetic influences, as well as wake-like alpha activity during sleep were reported as pathophysiological features of Nightmare Disorder. We hypothesized that in Nightmare Disorder, wake-like cortical activity and peripheral measures linked to arousals would be triggered by physiological processes related to the initiation of REM periods. Therefore, we examined electroencephalographic (EEG), motor and autonomous (cardiac) activity in a group of nightmare (NM) and healthy control (CTL) subjects during sleep-state-transitions while controlling for the confounding effects of trait anxiety. Based on the second-nights' polysomnographic recordings of 19 Nightmare Disordered (NM) and 21 control (CTL) subjects, we examined the absolute power spectra focusing on the alpha range, measures of heart rate variability (HRV) and motor (muscle tone) activity during pre-REM and post-REM periods, separately. According to our results, the NM group exhibited increased alpha power during pre-REM, but not in post-REM, or stable, non-transitory periods. While CTL subjects showed increased HRV during pre-REM periods in contrast to post-REM ones, NM subjects did not exhibit such sleep state-specific differences in HRV, but showed more stable values across the examined sleep stages and less overall variability reflecting generally attenuated parasympathetic activity during sleep-state-transitions and during stable, non-transitory NREM states. These differences were not mediated by waking levels of trait anxiety. Moreover, in both groups, significant differences emerged regarding cortical and motor (muscle tone) activity between pre-REM and post-REM conditions, reflecting the heterogeneity of NREM sleep. Our findings indicate that NM subjects' sleep is compromised during NREM-REM transitions, but relatively stabilized after REM periods. The coexistence of sleep-like and wake-like cortical activity in NM subjects seems to be triggered by REM/WAKE promoting

    Although smoking is the most common cannabis administration route, vaporization and consumption of cannabis edibles are common. Few studies directly compare cannabis' subjective and physiological effects following multiple administration routes. Subjective and physiological effects, and expired carbon monoxide (CO) were evaluated in frequent and occasional cannabis users following placebo (0.001% Δ(9)-tetrahydrocannabinol [THC]), smoked, vaporized, and oral cannabis (6.9% THC, ∼54mg). Participants' subjective ratings were significantly elevated compared to placebo after smoking and vaporization, while only occasional smokers' ratings were significantly elevated compared to placebo after oral dosing. Frequent smokers' maximum ratings were significantly different between inhaled and oral routes, while no differences in occasional smokers' maximum ratings between active routes were observed. Additionally, heart rate increases above baseline 0.5h after smoking (mean 12.2bpm) and vaporization (10.7bpm), and at 1.5h (13.0bpm) and 3h (10.2bpm) after oral dosing were significantly greater than changes after placebo, with no differences between frequent and occasional smokers. Finally, smoking produced significantly increased expired CO concentrations 0.25-6h post-dose compared to vaporization. All participants had significant elevations in subjective effects after smoking and vaporization, but only occasional smokers after oral cannabis, indicating partial tolerance to subjective effects with frequent exposure. There were no differences in occasional smokers' maximum subjective ratings across the three active administration routes. Vaporized cannabis is an attractive alternative for medicinal administrations over smoking or oral routes; effects occur quickly and doses can be titrated with minimal CO exposure. These results have strong implications for safety and abuse liability assessments. Published by Elsevier B.V.

    Full Text Available Old growth in the frequent-fire conifer forests of the western United States, such as those containing ponderosa pine (Pinus ponderosa, Jeffrey pine (P. jeffreyi, giant sequoia (Sequioa giganteum and other species, has undergone major changes since Euro-American settlement. Understanding past changes and anticipating future changes under different potential management scenarios are fundamental to developing ecologically based fuel reduction or ecological restoration treatments. Some of the many changes that have occurred in these forests include shifts from historically frequent surface fire to no fire or to stand-replacing fire regimes, increases in tree density, increased abundance of fire-intolerant trees, decreases in understory productivity, hydrological alterations, and accelerated mortality of old trees. Although these changes are widespread, the magnitude and causes of changes may vary within and among landscapes. Agents of change, such as fire exclusion or livestock grazing, likely interacted and had multiple effects. For example, historical ranching operations may have altered both fire regimes and understory vegetation, and facilitated institutional fire exclusion through fragmentation and settlement. Evidence exists for large variation in presettlement characteristics and current condition of old growth across this broad forest region, although there are many examples of striking similarities on widely distant landscapes. Exotic species, climate change, unnatural stand-replacing wildfires, and other factors will likely continue to degrade or eradicate old growth in many areas. As a policy of fire exclusion is proving to be unsustainable, mechanical tree thinning, prescribed fire, or wildland fire use will likely be key options for forestalling continued eradication of old growth by severe crown fires. For many practical and societal reasons, the wildland-urban interface may afford some of the most immediate opportunities for re

    Numerous abstracts related to inflammatory bowel disease (IBD) are presented at national conferences in the USA. The overall rate of publication of these abstracts as complete manuscripts is unknown . Abstracts submitted to the 2010 American College of Gastroenterology (ACG), Advances in Inflammatory Bowel Diseases (AIBD), and the American Gastroenterological Association abstracts at Digestive Disease Week (DDW) were reviewed. Each abstract was reviewed manually by two authors for type of research, study design, patient population, and outcome. Both PubMed and Google were then searched to determine whether the abstract was published as a full manuscript within five years of the conference. Univariate and multivariate logistic regression analysis was carried out using Stata 14.1. In total, 872 abstracts were reviewed. 49% (426/872) were published as complete manuscripts within five years of the conference. The average length of time to publication was 1.87 years (range 0-5). 42% of abstracts from ACG, 58% from AIBD, and 23% from DDW were eventually published (p < 0.0001). However, abstracts presented at DDW had the shortest time to publication compared to the other conferences (p = 0.002). Factors predictive of eventual publication include: number of authors (mean 7.5 for published vs 6.4 for unpublished p = 0.0001), clinical research compared to basic and translational (p = 0.026), and studies assessing drug safety with no adverse effects reported (p = 0.006). Nearly 50% of the abstracts presented at major gastroenterology conferences in the USA are published as full manuscripts 5 years after the conference. Further studies are needed to assess why so many abstracts are not published.

    Because of its expression pattern restricted to cells of the melanocytic lineage and to melanoma cells, Melan-A is an important target of immunotherapeutic approaches for the treatment of melanoma. Identification of Melan-A derived sequences recognized by specific T cells is therefore of great interest for the development of these therapeutic strategies. Using circulating CD4(+) T cells from healthy donors, we identified two Melan-A-derived CD4(+) T cell epitopes mapping to the 1-20 and 91-110 regions of the protein and restricted by HLA-DR11 and HLA-DR52 molecules, respectively. CD4(+) T cells specific for the identified epitopes were able to recognize the native antigen when endogenously expressed by antigen presenting cells and tumor cells. In addition, CD4(+) T cells specific for Melan-A 91-110 recognized the epitope after exogenous processing and presentation of Melan-A recombinant protein. Identification of these epitopes will be instrumental for the evaluation of the immune response to Melan-A in cancer patients.

    Viral causes of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are well recognised but only recently have rapid tests become available. To identify respiratory viruses in the general population and those associated with hospitalisation in AECOPD using polymerase chain reaction (PCR) on nasopharyngeal aspirate (NPA), and the relationship between symptoms, viral detection and inflammatory markers. A review of viruses detected in the general population in a health district between August 2014 and July 2015, using multiplex PCR for viruses from NPA samples. In addition, a single hospital, retrospective audit of patients admitted with suspected AECOPD was conducted. Of the 8811 NPA tested, 5599 (64%) were positive for at least one virus and 2069 of these were obtained from adults. In adults, the most common viruses identified were Influenza A (31%), Rhinovirus (27%) and respiratory syncytial virus A/B (10%). Most patients with AECOPD (102 of 153) had NPA sent for viral PCR testing and 59 (58%) were positive. The most common viruses identified were Influenza A (31%), Rhinovirus (24%) and respiratory syncytial virus A/B (17%) with co-infecting bacteria cultured in 22 sputum samples. Patients with influenza-like symptoms were more likely to have a positive viral PCR than those without symptoms (P < 0.004). The median C-reactive protein on admission was lower in the virus-infected than uninfected AECOPD (28 vs 60 mg/L, P < 0.026). The spectrum of viruses detected in patients with AECOPD is similar to that of the general population. Viruses are more likely to be identified in patients with AECOPD who present with influenza-like symptoms and a low C-reactive protein. © 2016 Royal Australasian College of Physicians.

    These secondary analyses used data from 2 similarly designed studies in subjects experiencing frequent heartburn to evaluate the efficacy of esomeprazole 20 mg once daily for 2 weeks, which reflects the approved over-the-counter dosage and duration. Subjects without endoscopically identified erosive esophagitis who were experiencing heartburn for ≥6 months and ≥4 of 7 days prior to baseline (study 1, N = 368; study 2, N = 349) were randomly assigned to receive double-blind treatment with esomeprazole 40 or 20 mg (administered as esomeprazole magnesium trihydrate 44.5 and 22.3 mg, respectively) or placebo once daily for 4 weeks. Subjects recorded the severity of heartburn in a daily diary, and investigators assessed subjects at each study visit. Two-week assessments were the primary end points of interest in these analyses and included the percentage of subjects with complete heartburn resolution (no episodes during 7 consecutive days), time to sustained complete heartburn resolution (the first of 7 consecutive episode-free days), and heartburn relief (no episodes other than ≤1 mild episode during 7 consecutive days). At week 2, the percentages of subjects who experienced complete heartburn resolution were significantly greater with esomeprazole 40 mg (study 1, 26.1%; study 2, 35.3%) and 20 mg (study 1, 25.2%; study 2, 35.7%) compared with placebo (study 1, 9.0%; study 2, 3.4%) (all, P ≤ 0.001). Beginning on day 1, the percentages of subjects who experienced sustained heartburn resolution was significantly greater in the groups treated with esomeprazole 40 mg (study 1, 19%; study 2, 19%; P esomeprazole 40 mg (study 1, 35.3%; study 2, 40.5%) and 20 mg (study 1, 34.5%; study 2, 46.4%) compared with placebo (study 1, 16.5%; study 2, 8.6%) (all, P ≤ 0.001). The results of this study demonstrate that once-daily treatment with esomeprazole 20 mg for 2 weeks effectively resolved subjects׳ heartburn compared with placebo, beginning on day 1.

    The objective of this study was to describe characteristics at diagnosis and outcomes of adults with soft tissue sarcoma. The authors conducted a retrospective multicenter study of 12,262 patients who were treated between January 1980 and 31 December 2013 in French Sarcoma Group centers and enrolled in the "Conticabase." Diagnoses were systematically reviewed by expert pathologists, and entities were classified according to the 2013 World Health Organization classification. Diagnostic characteristics, treatments, and outcomes are described for the entire cohort, for the subgroup of patients with translocation-related sarcomas, and for 9 different histologic subtypes. The results stressed the magnitude of heterogeneity among adult sarcomas. For example, compared with other sarcomas, translocation-related sarcomas (2143 tumors; 20.8%) were associated with a younger age at presentation (40.6 vs 60.0 years; P < .0001), a low rate of predisposing conditions (0.01% vs 22.3%; P < .0001), a higher rate of lymph node involvement (4.7% vs 1.3%; P < .0001), and a higher rate of synchronous metastasis (11.9% vs 6.7%; P < .001); and complete (R0) resection (41.6% vs 31.9%; P < .0001), receipt of (neo)adjuvant radiation therapy (62.6% vs 42.2%; P < .0001), and receipt of (neo)adjuvant chemotherapy (36.6% vs 22.3%; P < .0001) were significantly more frequent. Overall, translocation-related sarcomas were associated with a lower rate of local relapse (18.1% vs 26.0%; P < .0001) but a higher rate of metastatic relapse (42.0% vs 30.7%; P < .0001). Collaborative efforts are urgently needed to better assess the natural history and management options for every histologic subtype of sarcoma.

    Full Text Available Abstract Background It is known that the back muscles of scoliotic subjects present abnormalities in their fiber type composition. Some researchers have hypothesized that abnormal fiber composition can lead to paraspinal muscle dysfunction such as poor neuromuscular efficiency and muscle fatigue. EMG parameters were used to evaluate these impairments. The purpose of the present study was to examine the clinical potential of different EMG parameters such as amplitude (RMS and median frequency (MF of the power spectrum in order to assess the back muscles of patients presenting idiopathic scoliosis in terms of their neuromuscular efficiency and their muscular fatigue. Methods L5/S1 moments during isometric efforts in extension were measured in six subjects with idiopathic scoliosis and ten healthy controls. The subjects performed three 7 s ramp contractions ranging from 0 to 100% maximum voluntary contraction (MVC and one 30 s sustained contraction at 75% MVC. Surface EMG activity was recorded bilaterally from the paraspinal muscles at L5, L3, L1 and T10. The slope of the EMG RMS/force (neuromuscular efficiency and MF/force (muscle composition relationships were computed during the ramp contractions while the slope of the EMG RMS/time and MF/time relationships (muscle fatigue were computed during the sustained contraction. Comparisons were performed between the two groups and between the left and right sides for the EMG parameters. Results No significant group or side differences between the slopes of the different measures used were found at the level of the apex (around T10 of the major curve of the spine. However, a significant side difference was seen at a lower level (L3, p = 0.01 for the MF/time parameter. Conclusion The EMG parameters used in this study could not discriminate between the back muscles of scoliotic subjects and those of control subject regarding fiber type composition, neuromuscular efficiency and muscle fatigue at the level

The relative distributions of arsenic species, the primary methylation index (PMI = MMAV/iAs and the secondary methylation index (SMI = DMAV/MMAV were calculated to assess the metabolism of arsenic. Subjects with skin lesions had a higher concentration of urinary arsenic and a lower arsenic methylation capability than subjects without skin lesions. Women had a significantly higher methylation capability of arsenic than men, as defined by a higher percent DMAV and SMI in urine among women, which was the one possible interpretation of women with a higher concentration of urinary arsenic but lower susceptibility to skin lesions. The findings suggested that not only the dose of arsenic exposure but also the arsenic methylation capability have an impact on the individual susceptibility to skin lesions induced by coal arsenic exposure.

    To determine whether a variant bulimic-type presentation, whereby one meets criteria for bulimia nervosa (BN) except that binge eating episodes are not objectively large (i.e., "subjective bulimia nervosa," SBN), has comparable clinical severity to established eating disorders, particularly BN. Treatment-seeking adults with BN (N = 112), SBN (N = 28), anorexia nervosa restricting type (AN-R) (N = 45), and AN-binge/purge type (AN-B/P) (N = 24) were compared. Overall, SBN could not be meaningfully distinguished from BN. SBN and BN had equivalent eating pathology, depression and anxiety symptoms, low quality of life, impulsivity, Axis I comorbidity, and lifetime psychiatric history, and comparable clinical severity to AN-R and AN-B/P. Individuals with SBN, differing from BN only by the smaller size of their binge eating episodes, had a form of eating disorder comparable in clinical severity to threshold AN and BN and warranting clinical attention. Health professionals and the community require greater awareness of this variant to optimize detection, treatment-seeking, and outcomes. Copyright © 2012 Wiley Periodicals, Inc.

    Geothermal exploration projects have a significant amount of risk associated with uncertainties encountered in the discovery of the geothermal resource. Two of the largest challenges for increased geothermal deployment are 1) understanding when and how to proceed in an exploration program, and 2) when to walk away from a site. Current methodologies for exploration decision-making are formulatedby subjective expert opinion which can be incorrectly biased by expertise (e.g. geochemistry, geophysics), geographic location of focus, and the assumed conceptual model. The aim of this project is to develop a methodology for more objective geothermal exploration decision making at a given location, including go/no-go decision points to help developers and investors decide when to give up on alocation. In this scope, two different approaches are investigated: 1) value of information analysis (VOIA) which is used for evaluating and quantifying the value of a data before they are purchased, and 2) enthalpy-based exploration targeting based on reservoir size, temperature gradient estimates, and internal rate of return (IRR). The first approach, VOIA, aims to identify the value of aparticular data when making decisions with an uncertain outcome. This approach targets the pre-drilling phase of exploration. These estimated VOIs are highly affected by the size of the project and still have a high degree of subjectivity in assignment of probabilities. The second approach, exploration targeting, is focused on decision making during the drilling phase. It starts with a basicgeothermal project definition that includes target and minimum required production capacity and initial budgeting for exploration phases. Then, it uses average temperature gradient, reservoir temperature estimates, and production capacity to define targets and go/no-go limits. The decision analysis in this approach is based on achieving a minimum IRR at each phase of the project. This secondapproach was determined

    Compare brain potentials to consonant vowels (CVs) as a function of both voice onset times (VOTs) and consonant position; initial (CV) versus second (VCV). Auditory cortical potentials (N100, P200, N200, and a late slow negativity, (SN) were recorded from scalp electrodes in twelve normal hearing subjects to consonant vowels in initial position (CVs: /du/ and /tu/), in second position (VCVs: /udu/ and /utu/), and to vowels alone (V: /u/) and paired (VVs: /uu/) separated in time to simulate consonant voice onset times (VOTs). CVs evoked "acoustic onset" N100s of similar latency but larger amplitudes to /du/ than /tu/. CVs preceded by a vowel (VCVs) evoked "acoustic change" N100s with longer latencies to /utu/ than /udu/. Their absolute latency difference was less than the corresponding VOT difference. The SN following N100 to VCVs was larger to /utu/ than /udu/. Paired vowels (/uu/) separated by intervals corresponding to consonant VOTs evoked N100s with latency differences equal to the simulated VOT differences and SNs of similar amplitudes. Noise masking resulted in VCV N100 latency differences that were now equal to consonant VOT differences. Brain activations by CVs, VCVs, and VVs were maximal in right temporal lobe. Auditory cortical activities to CVs are sensitive to: (1) position of the CV in the utterance; (2) VOTs of consonants; and (3) noise masking. VOTs of stop consonants affect auditory cortical activities differently as a function of the position of the consonant in the utterance.

    Pelizaeus-Merzbacher Disease is an X-linked hypomyelinatiing leukodystrophy. We report mutations in the thyroid hormone transporter gene MCT8 in 11% of 53 families affected by hypomyelinating leukodystrophies of unknown aetiology. The 12 MCT8 mutated patients express initially a Pelizaeus-Merzbacher-Like disease phenotype with a latter unusual improvement of magnetic resonance imaging white matter signal despite absence of clinical progression. This observation underlines the interest of determining both free T3 and free T4 serum concentrations to screen for MCT8 mutations in young patients (<3 y) with a severe Pelizaeus-Merzbacher-Like disease presentation or older severe mentally retarded male patients with "hypomyelinated" regions.

    Full Text Available Mining frequent patterns in large transactional databases is a highly researched area in the field of data mining. Existing frequent pattern discovering algorithms suffer from many problems regarding the high memory dependency when mining large amount of data, computational and I/O cost. Additionally, the recursive mining process to mine these structures is also too voracious in memory resources. In this paper, we describe a more efficient algorithm for mining complete frequent itemsets from transactional databases. The suggested algorithm is partially based on FP-tree hypothesis and extracts the frequent itemsets directly from the tree. Its memory requirement, which is independent from the number of processed transactions, is another benefit of the new method. We present performance comparisons for our algorithm against the Apriori algorithm and FP-growth.

The elements to which we have referred are found in contemporary didactic and pedagogical proposals, because it is identified that purely cognitive or even cultural rights are not sufficient to understand the phenomena that happen in the classroom, or more broadly, in education as a whole. The analysis contemplated the publications of the past 3 symposia, and the results infer a small increase of citations of these elements. However, this growth must be questioned because the quotes are made in isolation, not being taken to support the analysis of the authors. In addition, this research also shows that the presence of these elements is very small compared with the total number of papers published in the events.

  2. Scalable Frequent Subgraph Mining

    Abdelhamid, Ehab

    2017-06-19

    A graph is a data structure that contains a set of nodes and a set of edges connecting these nodes. Nodes represent objects while edges model relationships among these objects. Graphs are used in various domains due to their ability to model complex relations among several objects. Given an input graph, the Frequent Subgraph Mining (FSM) task finds all subgraphs with frequencies exceeding a given threshold. FSM is crucial for graph analysis, and it is an essential building block in a variety of applications, such as graph clustering and indexing. FSM is computationally expensive, and its existing solutions are extremely slow. Consequently, these solutions are incapable of mining modern large graphs. This slowness is caused by the underlying approaches of these solutions which require finding and storing an excessive amount of subgraph matches. This dissertation proposes a scalable solution for FSM that avoids the limitations of previous work. This solution is composed of four components. The first component is a single-threaded technique which, for each candidate subgraph, needs to find only a minimal number of matches. The second component is a scalable parallel FSM technique that utilizes a novel two-phase approach. The first phase quickly builds an approximate search space, which is then used by the second phase to optimize and balance the workload of the FSM task. The third component focuses on accelerating frequency evaluation, which is a critical step in FSM. To do so, a machine learning model is employed to predict the type of each graph node, and accordingly, an optimized method is selected to evaluate that node. The fourth component focuses on mining dynamic graphs, such as social networks. To this end, an incremental index is maintained during the dynamic updates. Only this index is processed and updated for the majority of graph updates. Consequently, search space is significantly pruned and efficiency is improved. The empirical evaluation shows that the

    Physicians make subjective visual assessments concerning the race and/or ethnicity of their patients and document these assessments in patient histories every day. Medical students learn this practice through textbooks and the example set by their educators. Although physicians may believe that they are helping their patients, the practice of using visual clues concerning race and/or ethnicity to determine whether a patient is at risk of certain diseases lacks scientific rigor and may put the patient at significant risk of receiving substandard medical care. The authors argue that if the patient's race or ethnicity is of critical importance, the data should be collected through more objective, scientifically rigorous means, such as genetic testing. In this article, the authors call for the widespread transformation of the way medical schools teach tomorrow's physicians about the role of race and ethnicity in taking medical histories, and they challenge physicians to change their current practices.

    The current study investigates whether and how Facebook increases college-age users' subjective well-being by focusing on the number of Facebook friends and self-presentation strategies (positive vs. honest). A structural equation modeling analysis of cross-sectional survey data of college student Facebook users (N=391) revealed that the number of Facebook friends had a positive association with subjective well-being, but this association was not mediated by perceived social support. Additionally, we found that there was a negative curvilinear (inverted U-shape curve) relationship between Facebook friends and perceived social support. As for self-presentation strategies, whereas positive self-presentation had a direct effect on subjective well-being, honest self-presentation had a significant indirect effect on subjective well-being through perceived social support. Our study suggests that the number of Facebook friends and positive self-presentation may enhance users' subjective well-being, but this portion of happiness may not be grounded in perceived social support. On the other hand, honest self-presentation may enhance happiness rooted in social support provided by Facebook friends. Implications of our findings are discussed in light of affirmation of self-worth, time and effort required for building and maintaining friendships, and the important role played by self-disclosure in signaling one's need for social support.

    The problem of coping with stress is an important one in the context of development and persistence of alcohol dependence. In the literature to date very little attention has been paid to coping patterns construed as a configuration of specific coping styles, particularly as regards the functioning of addicted individuals. The aim of the study was to verify whether individuals with alcohol dependence characterized by different coping patterns differ with respect to the severity of psychopathological symptoms, defense mechanisms and time perspectives. Participants were given a battery of psychological tests-Coping Inventory for Stresfull Situations (CISS), Defense Style Questionnaire (DSQ 40), Syndrom Checklist (SCL-90) and Short Zimbardo Time Perspective Inventory (SZPTI-PL). The sample comprised 112 individuals with alcohol dependence, aged 20 to 63 years old, the average age was 37.86; 78 percent were men. There were identified three sub-groups of individuals characterized by a distinctive patterns of coping with stress -"emotional-avoidant", "task oriented" and a "mixed one". Individuals with the predominant emotional-avoidant coping pattern are characterized by significantly higher severity of psychopathological symptoms, less mature defense mechanisms and past time perspectives. Subjects reliant on task-oriented coping pattern were characterized by the highest level of adaptation and the most constructive way of functioning in the face of difficulties. It is worth regarding the examination of patterns of coping as an indispensable element of collecting medical history from alcohol dependent individuals.

    The management of corporate social responsibility (CSR) has recently become a critical concern for companies in advanced countries. For universities, there is a requirement to contribute to the promotion of CSR, resulting in graduates who have sufficient cognition of and a good attitude towards CSR. In addition, universities have social responsibilities, which can be called "University Social Responsibility (USR)." On the basis of the concepts of the guidelines for CSR in the "Green Paper," which was presented by the European Committee (EC) in 2001, we provide a perspective here on what factors dictate the establishment of education programs for social responsibilities at universities. These factors include an outline of the concepts and the significance of CSR, social ethics and the morals of higher education and research, compliances, human resource management, human rights, safety and health in academic settings, and various concerns regarding environmental safety and preservation. Additionally, through the concept postulated here for social responsible education, in this paper, we introduce the present activity at the University of Tokyo (UT) in terms of the education program for CSR and USR, proposing that the future establishment of university-wide education programs based on the concept of CSR and the value of sustainability is required at UT.

The objective of the current study was to examine the recall order of words presented on lists and to determine if age affects recall sequence. Physically and psychologically healthy male subjects were divided into two groups according to age, i.e., 23 young subjects (20 to 30 years) and 50 elderly subjects (60 to 70 years) submitted to the Wechsler Adult Intelligence Scale-Revised and the free word recall test. The order of word presentation significantly affected the 3rd and 4th words recalled (P recalled the last words presented from each list (words 13-15) significantly more times 3rd and 4th than words presented in all remaining positions (P word presentation also significantly affected the 5th and 6th words recalled (P = 0.05; F = 7.5) and there was a significant interaction between the order of presentation and the type of list presented (P term memory (episodic declarative).

    Microbial induced corrosion (MIC) is not as rare as many materials scientist and corrosion practitioners do believe. It is not an exotic and scarce event, but can be found frequently in many fields of corrosion research, provided that it is looked for. The reason for the relatively few descriptions of MIC cases seems to be the fact, that the microbiological approach is not widely known and applied in the world of materials science. MIC is not so much a corrosion mechanism on its own, but it enhances the corrosion rates of the 'normal' mechanisms to such an extent, that in some cases 'incredible' fast corrosion progress can be observed. The reason is the microorganisms' function as bio-catalysts: Chemical reactions, which are very slow under normal chemical conditions can be highly accelerated by living organisms. Besides that, several microorganisms do produce very corrosive substances which in natural environments do not occur without the activity of microorganisms, e. g. sulfuric or nitric acid. We want to point out, that it can be very worthy to take microbial induced corrosion into account. MIC is not the general answer for all unsolved corrosion problems, but to think about it helps in many corrosion cases as the authors had to experience. The initial indication for the presence of MIC are markedly increased corrosion rates. In the following, some of our 'lessons' are presented as short case studies: Two of them deal with steel corrosion characterized by increased corrosion rates. The third example presents corrosion damage of aluminium structures, where from a technical point of view corrosion was not expected, least of all microbial induced corrosion. (authors)

    On frequent elements in coals: in the case of bioelements (H, C, N, O) even bare quantities may offer evidence of origin and transformation of coals. With those as with other frequent elements it is not so much quantity (as is still with S), as variability, and ratios of pairs of elements, which may give evidence of transformation. Enrichments in different plants and tissues - excepting H, C, N, O - are extremely different in different samples. In coalification original contents are lowered, mixed, or veiled by import. Influences of surroundings change during the stages of coalification, while the surroundings themselves are in continual transformation. Only with frequent elements one may hope to recognize traces of original conditions. More exact knowledge of seams may help in prospection and parallelization.

    Auditory training consists of the exercises taking advantage of the environmental sounds and human speech; it is designed to ensure hearing for a person suffering its impairment within the range of acoustic experiences comparable with that of the normally hearing subjects. The successful treatment of partial deafness with the use of a cochlear implant (CI) resulted in the increase of the number of patients who needed auditory training to enable them to recognize mid-and high-frequency sounds. Bearing in mind the lack of the teaching aids permitting to adequately address the specific hearing problems in such patients, the Rehabilitation Clinic of the Institute of Physiology and Pathology of Hearing undertook to develop the relevant materials to satisfy the needs of auditory training following surgical cochlear implantation. The evaluation, by the patients suffering partial deafness and speech therapists, of the usefulness and the difficulty of the proposed auditory training based on the use of environmental sounds and human speech in the mid- and high-frequency ranges. The study included 29 adult CI users presenting with partial deafness participating in the Institute's rehabilitation program. Both the patients and the speech therapists independently evaluated the usefulness of the proposed training and the difficulties encountered with its practical realization by completing the questionnaire according to the Likert 5-point scale. The patients with partial deafness and speech therapists found out that the proposed auditory training was difficult to perform; this inference was especially true as regards the exercises designed to enable the identification of the mid- and high frequency speech sounds. The women experienced significantly more difficulties than men when performing the proposed exercises. Both the patients and the speech therapists confirmed the usefulness of the recommended auditory training as a component of the rehabilitation process. The surgical

    Full Text Available Background. The NT-ProBNP/BNP test has been validated as a marker for determining the etiology of acute dyspnea. In the setting of end-stage renal disease on hemodialysis (ESRD on HD, the utility of the NT-ProBNP/BNP test has not been validated. This study examines the clinical utility of the NT-ProBNP test in the setting of ESRD on HD patients presenting with acute dyspnea. Methods. A retrospective case series of 250 subjects were admitted to Cooper University Hospital, 07/2010-03/2011, with ESRD and HD presenting with dyspnea. The incidences of echocardiography, cardiology consultation, and NT-ProBNP elevated and normal were examined. Correlation coefficients were calculated for NT-ProBNP with age (years, estimated dry weight (kg, amount of fluid removed (L, and ejection fraction (EF in % among other echocardiography parameters. Results. Of the total sample 235 patients had NT-ProBNP levels performed. Cardiology consults were placed in 68.8% and 58% who underwent echocardiography. Of those for whom an echocardiography was performed estimated mean EFs of 54.6%, 50.8%, and 61.7% were observed among the NT-ProBNP elevated group, normal group, and no NT-ProBNP group, respectively. No differences were detected in all other echocardiography measurements. No correlation was observed between NT-ProBNP and age (, baseline EDW (, amount of fluid removed (, or EF (. Conclusion. In the setting of ESRD on HD, the NT-ProBNP test has no clinical utility in determining the etiology of acute dyspnea. This can be demonstrated through echocardiographic and therapeutic parameters measured in this study.

    This material intends to present three clinical observations regarding the uveitis etiology, that is represented by the association of some etiological factors less known: Toxoplasma gondii, Listeria monocytogenes, Leptospira icterohaemorrhagiae. The uveitis described here have been severe in the fast evolution and with trends of reappearence. This work demonstrates that the strict etiological antibacteria and antiparasite therapy is not enough and only corticotherapy is able to fight against the accentuated inflammatory phenomena that go along with type of uveitis.

    The current influx of refugees and the high rate of immigration increase the rate and impact of infectious diseases in Europe. Infections can be detected at the initial examination of arriving refugees as a result of systematic screening or within the framework of general medical care. Diagnosis and treatment require special expertise and in some cases special precautions. The spectrum of infections is determined by the country of origin of migrants and the conditions experienced on fleeing to Germany. In this article the diagnostics and treatment of the most important infections are presented. As far as infections are concerned refugees and migrants do not represent a threat to the general population but instead have to be perceived as a highly vulnerable group.

    Several variables lead to changes in human and animal eating behaviour and food choices. A pivotal role is played by food palatability, represented by food, smell, taste, texture, appearance and temperature. The aim of our study is to assess the potential differences in palatability and digestibility of four different flavoured iced desserts, consumed at the end of a standardized meal, and their impact on the emotional status of 60 healthy volunteers. Sixty healthy volunteers, after ENT and psychological assessment, were asked to fill out a Psycho-Emotional Questionnaire (PEQ) to assess their basal emotional pattern before the consumption of an iced dessert at the end of a standard meal, after which they completed an Organoleptic-Sensory Questionnaire (OSQ), a Dynamic Digestibility Questionnaire (DDQ) and again the PEQ. Four different flavors (lemon, tangerine, pineapple and chocolate) were tested on 4 consecutive days on the same subjects. Most of the 60 subjects, by means of OSQ, found taste, aspect, texture and smell of the 4 flavours pleasant, lemon and tangerine were the freshest and lightest. The DDQ identified pineapple and chocolate dessert as those less digestible. By means of PEQ we recorded an improvement in joy, mood and activation, associated with good data of digestibility and palatability after the consumption of all flavors. Our data showed that all flavors improve joy, mood and activation, after their consumption, without statistically significant differences. However, among the tested flavours, lemon and tangerine appear to be the most pleasant and those which facilitate the digestive process.

Furthermore, more RPV/FTC/TDF-treated subjects with baseline HIV-1 RNA >100,000 copies/mL developed resistance compared to subjects with baseline HIV-1 RNA ≤100,000 copies/mL. Here, deep sequencing was utilized to assess the presence of pre-existing low-frequency variants in subjects with and without resistance development in the STaR study. Deep sequencing (Illumina MiSeq was performed on baseline and virologic failure samples for all subjects analyzed for resistance by population sequencing during the clinical study (n = 33, as well as baseline samples from control subjects with virologic response (n = 118. Primary NRTI or NNRTI drug resistance mutations present at low frequency (≥2% to 20% were detected in 6.6% of baseline samples by deep sequencing, all of which occurred in control subjects. Deep sequencing results were generally consistent with population sequencing but detected additional primary NNRTI and NRTI resistance mutations at virologic failure in seven samples. HIV-1 drug resistance mutations emerging while on RPV/FTC/TDF or EFV/FTC/TDF treatment were not present at low frequency at baseline in the STaR study.

Since the JAERI Takasaki was founded as the center of the research and development on radiation chemistry, a lot of outcomes have been obtained in the research and development of radiation application using large-sized {sup 60}Co gamma ray irradiation facilities and high power electron accelerators, etc. After the ion irradiation research facility (TIARA) started operation, many outstanding outcomes have been obtained in the research of up-to-date science and technologies in the fields of material science and bio-technology, etc., making use of ions in addition to gamma rays and electron beams. Although these results of the research are mainly produced experimentally, theoretical analyses also are thought to be important because these results will be applied and expanded in future. We aim to set up 'Theoretical Analysis Group for Radiation Application' in fiscal 2003, and we aim at performing theoretical and engineering analyses about phenomena and things such as radiation chemical reactions, irradiation/implantation effects to semiconductors, model for plant function, etc. The irradiation effects of charged particles to materials are divided into the primary effects like generation of radicals and lattice defects, etc., which occurs immediately after charged particles impinge on materials, and the secondary effects like chemical changes and physical changes caused in materials as a result of the primary effects. The subjects of our analytical research are the analyses of the secondary effects and the systems which utilize the chemical and the physical changes to the radiation application

    Pica, the compulsive consumption of ice or other nonnutritious substances, is associated with iron deficiency, a common negative consequence of frequent blood donation. Because of this, blood donors, such as those participating in the Strategies to Reduce Iron Deficiency (STRIDE) study, are an ideal population to explore pica and iron deficiency. STRIDE was a 2-year intervention trial to assess the effectiveness of iron supplementation for mitigating iron deficiency in frequent blood donors. Subjects completed baseline and follow-up questionnaires that included questions about pica symptoms. In-depth telephone interviews were conducted with 14 of these subjects reporting pica symptoms and eight presumed controls (casual ice chewers) to gain a deeper understanding of pica symptoms and their impact on daily life and to make a final determination on the presence of pica. Pica was confirmed in five of the 14 subjects reporting symptoms and in two of eight controls. Outcome misclassification based on the questionnaire was attributed to inadequate assessment of several pica symptoms identified during the interview. Comparison of subjects' repeated quantitative iron measurements taken throughout STRIDE with subjects' final adjudicated pica status revealed a positive relationship between development of pica and worsening iron status; the opposite was found in those whose pica symptoms resolved. Continued refinement of pica symptom questions will allow for rapid and accurate detection of pica in frequent blood donors and confirmation of successful treatment with iron supplements. © 2016 AABB.

    There is no common understanding of how needs of emergency department (ED) frequent users differ from other patients. This study sought to examine how to best serve this population. Examinations of why ED frequent users present to the ED, what barriers to care exist, and what service offerings may help these patients achieve an optimal level of health were conducted. We performed a prospective study of frequent ED users in an adult only, level 1 trauma center with approximately 90,000 visits per year. Frequent ED users were defined as those who make four or more ED visits in a 12 month period. Participants were administered a piloted structured interview by a trained researcher querying demographics, ED usage, perceived barriers to care, and potential aids to maintaining health. Of 1,523 screened patients, 297 were identified as frequent ED users. One hundred frequent ED users were enrolled. The mean age was 48 years (95% CI 45-51). The majority of subjects were female (64%, 64/100, 95% CI 55-73%), white (61%, 60/98, 95% CI 52-71%) and insured by Medicaid (55%, 47/86, 95% CI 44-65%) or Medicare (23%, 20/86, 95% CI 14-32%). Subjects had a median of 6 ED visits, and 2 inpatient admissions in the past 12 months at this hospital. Most frequent ED users (61%, 59/96, 95% CI 52-71%) stated the primary reason for their visit was that they felt that their health problem could only be treated in an ED. Transportation presented as a major barrier to few patients (7%, 7/95, 95% CI 3-14%). Subjects stated that "after-hours options, besides the ED for minor health issues" (63%, 60/95, 95% CI 53-73%) and having "a nurse to work with you one-on-one to help manage health care needs" (53%, 50/95, 95% CI 43-63%) would be most helpful in achieving optimal health. This study characterized ED frequent users and identified several opportunities to better serve this population. By understanding barriers to care from the patient perspective, health systems can potentially address unmet

  18. Performance Evaluation of Frequent Subgraph Discovery Techniques

    Directory of Open Access Journals (Sweden)

    Saif Ur Rehman

    2014-01-01

    Full Text Available Due to rapid development of the Internet technology and new scientific advances, the number of applications that model the data as graphs increases, because graphs have highly expressive power to model a complicated structure. Graph mining is a well-explored area of research which is gaining popularity in the data mining community. A graph is a general model to represent data and has been used in many domains such as cheminformatics, web information management system, computer network, and bioinformatics, to name a few. In graph mining the frequent subgraph discovery is a challenging task. Frequent subgraph mining is concerned with discovery of those subgraphs from graph dataset which have frequent or multiple instances within the given graph dataset. In the literature a large number of frequent subgraph mining algorithms have been proposed; these included FSG, AGM, gSpan, CloseGraph, SPIN, Gaston, and Mofa. The objective of this research work is to perform quantitative comparison of the above listed techniques. The performances of these techniques have been evaluated through a number of experiments based on three different state-of-the-art graph datasets. This novel work will provide base for anyone who is working to design a new frequent subgraph discovery technique.

    Full Text Available Abstract Background Asperger syndrome (AS is a neurodevelopmental disorder belonging to autism spectrum disorders with prevalence rate of 0,35% in school-age children. It has been most extensively studied in childhood while there is scarcity of reports concerning adulthood of AS subjects despite the lifelong nature of this syndrome. In children with Asperger syndrome the initiation and continuity of sleep is disturbed because of the neuropsychiatric deficits inherent of AS. It is probable that sleep difficulties are present in adulthood as well. Our hypothesis was that adults with AS suffer from difficulty in initiating and maintaining sleep and nonrestorative sleep (insomnia. Methods 20 AS without medication were compared with 10 healthy controls devoid of neuropsychiatric anamnesis. Clinical examination, blood test battery and head MRI excluded confounding somatic illnesses. Structured psychiatric interview for axis-I and axis-II disorders were given to both groups as well as Beck Depression Inventory and Wechsler adult intelligence scale, revised version.

    Background Asperger syndrome (AS) is a neurodevelopmental disorder belonging to autism spectrum disorders with prevalence rate of 0,35% in school-age children. It has been most extensively studied in childhood while there is scarcity of reports concerning adulthood of AS subjects despite the lifelong nature of this syndrome. In children with Asperger syndrome the initiation and continuity of sleep is disturbed because of the neuropsychiatric deficits inherent of AS. It is probable that sleep difficulties are present in adulthood as well. Our hypothesis was that adults with AS suffer from difficulty in initiating and maintaining sleep and nonrestorative sleep (insomnia). Methods 20 AS without medication were compared with 10 healthy controls devoid of neuropsychiatric anamnesis. Clinical examination, blood test battery and head MRI excluded confounding somatic illnesses. Structured psychiatric interview for axis-I and axis-II disorders were given to both groups as well as Beck Depression Inventory and Wechsler adult intelligence scale, revised version. Sleep quality was assessed with sleep questionnaire, sleep diary during 6 consecutive days and description of possible sleep problems by the participants own words was requested. Results compared with controls and with normative values of good sleep, AS adults had frequent insomnia. In sleep questionnaire 90% (18/20), in sleep diary 75% (15/20) and in free description 85% (17/20) displayed insomnia. There was a substantial psychiatric comorbidity with only 4 AS subject devoid of other axis-I or axis-II disorders besides AS. Also these persons displayed insomnia. It can be noted that the distribution of psychiatric diagnoses in AS subjects was virtually similar to that found among patient with chronic insomnia.

    Works cited in six forensic psychology journals published 2008-2010 were counted to identify the most frequently cited journals. The sample of works cited (N = 21,776) was not a definitive ranked list of important journals in forensic psychology, but was large enough to indicate high-impact journals. The list of frequently cited publications included more general psychiatry and psychology journals than titles specific to forensic psychology. The implications of the proportion of general versus specific titles for collections supporting research in forensic psychology were discussed.

  5. Enumerating all maximal frequent subtrees in collections of phylogenetic trees

    Science.gov (United States)

    2014-01-01

    Background A common problem in phylogenetic analysis is to identify frequent patterns in a collection of phylogenetic trees. The goal is, roughly, to find a subset of the species (taxa) on which all or some significant subset of the trees agree. One popular method to do so is through maximum agreement subtrees (MASTs). MASTs are also used, among other things, as a metric for comparing phylogenetic trees, computing congruence indices and to identify horizontal gene transfer events. Results We give algorithms and experimental results for two approaches to identify common patterns in a collection of phylogenetic trees, one based on agreement subtrees, called maximal agreement subtrees, the other on frequent subtrees, called maximal frequent subtrees. These approaches can return subtrees on larger sets of taxa than MASTs, and can reveal new common phylogenetic relationships not present in either MASTs or the majority rule tree (a popular consensus method). Our current implementation is available on the web at https://code.google.com/p/mfst-miner/. Conclusions Our computational results confirm that maximal agreement subtrees and all maximal frequent subtrees can reveal a more complete phylogenetic picture of the common patterns in collections of phylogenetic trees than maximum agreement subtrees; they are also often more resolved than the majority rule tree. Further, our experiments show that enumerating maximal frequent subtrees is considerably more practical than enumerating ordinary (not necessarily maximal) frequent subtrees. PMID:25061474

    Full Text Available Abstract Background General Practitioners spend a disproportionate amount of time on frequent attenders. So far, trials on the effect of interventions on frequent attenders have shown negative results. However, these trials were conducted in short-term frequent attenders. It would be more reasonable to target intervention at persistent frequent attenders. Typical characteristics of persistent frequent attenders, as opposed to 1-year frequent attenders and non-frequent attenders, may generate hypotheses regarding modifiable factors on which new randomized trials may be designed. Methods We used the data of all 28,860 adult patients from 5 primary healthcare centers. Frequent attenders were patients whose attendance rate ranked in the (age and sex adjusted top 10 percent during 1 year (1-year frequent attenders or 3 years (persistent frequent attenders. All other patients on the register over the 3-year period were referred to as non-frequent attenders. The lists of medical problems coded by the GP using the International Classification of Primary Care (ICPC were used to assess morbidity. First, we determined which proportion of 1-year frequent attenders was still a frequent attender during the next two consecutive years and calculated the GPs' workload for these patients. Second, we compared morbidity and number of prescriptions for non-frequent attenders, 1-year frequent attenders and persistent frequent attenders. Results Of all 1-year frequent attenders, 15.4% became a persistent frequent attender equal to 1.6% of all patients. The 1-year frequent attenders (3,045; 10.6% were responsible for 39% of the face-to-face consultations; the 470 patients who would become persistent frequent attenders (1.6% were responsible for 8% of all consultations in 2003. Persistent frequent attenders presented more social problems, more psychiatric problems and medically unexplained physical symptoms, but also more chronic somatic diseases (especially diabetes

    Disposable and frequent replacement contact lenses dominate the marketplace. They are available in a wide variety of parameters for use in refractive errors, including myopia, hyperopia, astigmatism, and presbyopia. They are convenient and affordable and lend themselves to most wearing modalities, including daily wear, flexible wear, and extended wear for up to 30 days. In addition, they have been shown to be the most trouble-free contact lens wear modality for daily wear or extended wear. They are an appropriate choice for patients who desire occasional contact lens wear and have gained wide acceptance as therapeutic bandage contact lenses. Disposable and frequent replacement lenses will remain important modalities for some time to come as the variety of contact lenses and contact lens parameters that are offered continue to expand. New contact lens varieties, such as the high-Dk silicone hydrogel lenses, will further expand the role of these contact lenses in vision correction.

    Emergency department (ED) crowding is associated with increased morbidity and mortality. Its etiology is multifactorial, and frequent ED use (defined as more or equal to five visits per year) is a major contributor to high patient volumes. Our primary objective is to characterize the frequent user population. Our secondary objective is to examine risk factors for frequent emergency use. We conducted a retrospective cohort study of pediatric emergency department (PED) visits at the Montreal Children's Hospital using the Système Informatique Urgence (SIURGE), electronic medical record database. We analysed the relation between patient's characteristics and the number of PED visits over a 1-year period following the index visit. Patients totalling 52,088 accounted for 94,155 visits. Of those, 2,474 (4.7%) patients had five and more recurrent visits and accounted for 16.6% (15,612 visits) of the total PED visits. Lower level of acuity at index visit (odds ratio [OR] 0.85) was associated with a lower number of recurrent visits. Lower socioeconomic status (social deprivation index OR 1.09, material deprivation index OR 1.08) was associated with a higher number of recurrent visits. Asthma (OR 1.57); infectious ear, nose, and sinus disorders (OR 1.33); and other respiratory disorders (OR 1.56) were independently associated with a higher incidence of a recurrent visit within the year following the first visit. Our study is the first Canadian study to assess risk factors of frequent pediatric emergency use. The identified risk factors and diagnoses highlight the need for future evidence-based, targeted innovative research evaluating strategies to minimize ED crowding, to improve health outcomes and to improve patient satisfaction.

    Information about the spatial characteristics of high and extreme streamflow is often needed for an accurate analysis of flood risk and effective co-ordination of flood related activities, such as flood defence planning. In this study we analyse the spatial dependence of frequent floods in Switzerland across different scales. Firstly, we determine the average length of high and extreme flow events for 56 runoff time series of Swiss rivers. Secondly, a dependence measure expressing the probability that streamflow peaks are as high as peaks at a conditional site is used to describe and map the spatial extend of joint occurrence of frequent floods across Switzerland. Thirdly, we apply a cluster analysis to identify groups of sites that are likely to react similarly in terms of joint occurrence of high flow events. The results indicate that a time interval with a length of 3 days seems to be most appropriate to characterise the average length of high streamflow events across spatial scales. In the main Swiss basins, high and extreme streamflows were found to be asymptotically independent. In contrast, at the meso-scale distinct flood regions, which react similarly in terms of occurrence of frequent flood, were found. The knowledge about these regions can help to optimise flood defence planning or to estimate regional flood risk properly.

  14. Frequent video game players resist perceptual interference.

    Directory of Open Access Journals (Sweden)

    Aaron V Berard

    Full Text Available Playing certain types of video games for a long time can improve a wide range of mental processes, from visual acuity to cognitive control. Frequent gamers have also displayed generalized improvements in perceptual learning. In the Texture Discrimination Task (TDT, a widely used perceptual learning paradigm, participants report the orientation of a target embedded in a field of lines and demonstrate robust over-night improvement. However, changing the orientation of the background lines midway through TDT training interferes with overnight improvements in overall performance on TDT. Interestingly, prior research has suggested that this effect will not occur if a one-hour break is allowed in between the changes. These results have suggested that after training is over, it may take some time for learning to become stabilized and resilient against interference. Here, we tested whether frequent gamers have faster stabilization of perceptual learning compared to non-gamers and examined the effect of daily video game playing on interference of training of TDT with one background orientation on perceptual learning of TDT with a different background orientation. As a result, we found that non-gamers showed overnight performance improvement only on one background orientation, replicating previous results with the interference in TDT. In contrast, frequent gamers demonstrated overnight improvements in performance with both background orientations, suggesting that they are better able to overcome interference in perceptual learning. This resistance to interference suggests that video game playing not only enhances the amplitude and speed of perceptual learning but also leads to faster and/or more robust stabilization of perceptual learning.

    Cannabinoids have been shown to alter time perception, but existing literature has several limitations. Few studies have included both time estimation and production tasks, few control for subvocal counting, most had small sample sizes, some did not record subjects' cannabis use, many tested only one dose, and used either oral or inhaled administration of Δ⁹-tetrahydrocannabinol (THC), leading to variable pharmacokinetics, and some used whole-plant cannabis containing cannabinoids other than THC. Our study attempted to address these limitations. This study aims to characterize the acute effects of THC and frequent cannabis use on seconds-range time perception. THC was hypothesized to produce transient, dose-related time overestimation and underproduction. Frequent cannabis smokers were hypothesized to show blunted responses to these alterations. IV THC was administered at doses from 0.015 to 0.05 mg/kg to 44 subjects who participated in several double-blind, randomized, counterbalanced, crossover, placebo-controlled studies. Visual time estimation and production tasks in the seconds range were presented to subjects three times on each test day. All doses induced time overestimation and underproduction. Chronic cannabis use had no effect on baseline time perception. While infrequent/nonsmokers showed temporal overestimation at medium and high doses and temporal underproduction at all doses, frequent cannabis users showed no differences. THC effects on time perception were not dose related. A psychoactive dose of THC increases internal clock speed as indicated by time overestimation and underproduction. This effect is not dose related and is blunted in chronic cannabis smokers who did not otherwise have altered baseline time perception.

    A field for cancerization, or a field defect, is formed by the accumulation of genetic and epigenetic alterations in normal-appearing tissues, and is involved in various cancers, especially multiple cancers. Epigenetic alterations are frequently present in chronic inflammation-exposed tissues, but information on individual genes involved in the formation of a field defect is still fragmental. Here, using non-cancerous gastric tissues of cancer patients, we isolated 16 aberrantly methylated genes, and identified chromatin remodelers ACTL6B and SMARCA1 as novel genes frequently methylated in non-cancerous tissues. SMARCA1 was expressed at high levels in normal gastric tissues, but was frequently silenced by aberrant methylation in gastric cancer cells. Moreover, somatic mutations of additional chromatin remodelers, such as ARID1A, SMARCA2, and SMARCA4, were found in 30% of gastric cancers. Mutant allele frequency suggested that the majority of cancer cells harbored a mutation when present. Depletion of a chromatin remodeler, SMARCA1 or SMARCA2, in cancer cell lines promoted their growth. These results showed that epigenetic and genetic alterations of chromatin remodelers are induced at an early stage of carcinogenesis and are frequently involved in the formation of a field defect.

The method of diagnosis and management of such injuries is well established and accepted. However, trauma to the bladder can be associated with other life-threatening injuries which are frequently missed, and often diagnosed during laparotomy for other reasons. The aim of this study was to diagnose bladder injury in polytrauma patients as early as possible, taking into consideration the fact that these patients are hemodynamically unstable and require rapid evaluation and management. In order to achieve our objective, we used bedside sonography with retrograde instillation of normal saline to diagnose bladder injury in addition to use of the conventional retrograde cystogram.Keywords: bladder injury, bladder rupture, retrograde cystogram

    Laparoscopic cholecystectomy reduces postoperative pain, hospital stay and recovery in comparison with the open procedure. This approach allows to treat most of vesicular pathologies, as acute cholecystitis and choledocal lithiasis, with excellent results. Biliary tract injuries represent however the most feared complication. Concerning groin hernia pathology, two different laparoscopic approaches are described, as the trans-abdominal pre-peritoneal approach (TAPP) and the total extra-peritoneal approach (TEP). The first technique is easier to perform, but associated with more frequent significant intraabdominal morbidity. Results are comparable to the classic open Lichtenstein technique in term of reccurence. Laparoscopic approach could be associated with a lower chronic pain rate, but further studies should confirm this statement.

    Full Text Available It is possible to conduct an analysis of the incidence of viral diseases in calves if these diseases are divided into two basic groups. One group comprises diseases of respiratory organs which are manifested by symptoms of a respiratory syndrome, and the second group comprises diseases of digestive tract organs in the form of a gastrointestinal syndrome. It is considered that viruses have the dominant role in the complex etiology of the respiratory syndrome, primarily the IBR virus or the Bovine Herpes Virus-1 (BHV-1, followed by the parainfluenza 3 virus (RSV, the Bovine Viral Diahrrea Virus (BVDV, the bovine Respiratory Syncytial Virus (RSV, but also other viruses, such as adenoviruses, rhinoviruses, coronaviruses, can also influence the appearance of the respiratory syndrome. The respiratory syndrome is rarely caused by a single viral agent, but most frequently by mixed viruses, but also by bacterial infections. Mixed viral infections often have a lethal outcome. Investigations of the etiology of the gastrointestinal syndrome so far indicate that, in addition to bacteria, viruses can also be a significant etiological factor. Rotaviruses, coronaviruses, adenoviruses parvoviruses, herpesviruses (the IBR virus, pestiviruses (BVDV, can be the causes of a gastrointestinal syndrome. It is believed that viruses can be the cause in about 10% cases in the ethiopathogenesis of this syndrome. The paper describes the etiopathogenesis of calf diseases of viral etiology which are most often found in the local conditions of industrial breeding of calves.

    C/EBPalpha (CCAAT/enhancer binding protein alpha) belongs to the family of leucine zipper transcription factors and is necessary for transcriptional control of granulocyte, adipocyte and hepatocyte differentiation, glucose metabolism and lung development. C/EBPalpha is encoded by an intronless gene. CEBPA mutations cause a myeloid differentiation block and were detected in acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), multiple myeloma and non-Hodgkin's lymphoma (NHL) patients. In this study we identified in 41 individuals from 824 screened individuals (290 AML patients, 382 MDS patients, 56 NHL patients and 96 healthy individuals) a single class of 23 deletions in CEBPA gene which involved a direct repeat of at least 2 bp. These mutations are characterised by the loss of one of two same repeats at the ends of deleted sequence. Three most frequent repeats included in these deletions in CEBPA gene are CGCGAG (493-498_865-870), GCCAAGCAGC (508-517_907-916) and GG (486-487_885-886), all according to GenBank accession no. NM_004364.2. A mechanism for deletion formation between two repetitive sequences can be recombination events in the repair process. Double-stranded cut in DNA can initiate these recombination events of adjacent DNA sequences.

Our intention is to give a simple introduction to the physics of gases that would be helpful for newcomers to the field of hypoxia research. We will provide background knowledge about questions often asked, but without straightforward answers. What is O2 concentration, and what is O2 partial pressure? What is normoxia, and what is hypoxia? How much O2 is experienced by a cell residing in a culture dish in vitro vs in a tissue in vivo? By the way, the O2 concentration in a normoxic incubator is 18.6%, rather than 20.9% or 20%, as commonly stated in research publications. And this is strictly only valid for incubators at sea level.

    Rother, U; Schwarz, H M

    1976-01-01

    The authors analysed 2000 intra-oral radiographs that had been taken, using the bisecting technique according to the isometry rule of Cieszynski/Dieck, at an institution being typical of the ambulatory public health service during a period of 5 months. 602 (30.1%) faulty radiographs were detected. The classification of the faulty radiographs showed that 395 (65.6%) were caused by errors in projection; 116 (19.3%), by errors in the dark-room; 59 (9.8%), by errors in exposure; and 32 (5.3%), by defective equipment. Defects in the film material used in the present study were not observed. The relatively high rate of faults calls for improvements of the programs for the education and the advanced training of stomatologists and stomatological nurses, and for improvement of the radiographic technique.

    2014-04-01

    Pycnodysostosis is a rare disease caused by a dysfunction of the osteoclasts due to a mutation in the cathepsin K gene. We present a case of a young adult patient with the above mentioned syndrome, who suffered an atypical fracture of the tibia after a low energy fall. Some bone changes that could have predisposed the fracture were observed when examined in the Emergency Department. Not long afterwards he suffered the same type of fracture in another tibia. Due to the conditions typical of the pycnodysostosis, the above mentioned fracture required an unconventional approach for this mid-shaft tibial fracture (osteosynthesis plate), combined with a longer consolidation time. The case was finally resolved satisfactorily. Copyright © 2013 Sociedad Española de Médicos de Atención Primaria (SEMERGEN). Publicado por Elsevier España. All rights reserved.

    To describe the distribution of frequent attenders (FA) through the different primary care practices in Cordoba-Guadalquivir Health District (Córdoba, Spain). An ecological study was performed, including data from 2011 to 2015. Defining FA as those subjects who made12 or more appointments per year; independently analysed for nursing, general practice and paediatrics. Prevalence of frequent attendance and FA/professional ratio were used as dependent variables. Demographic characteristics from district population, number of health professionals and use of general facilities were also examinated. Aiming to understand FA distribution, primary health settings were classified according to facility size and environmental location (urban, suburban and rural). The mean prevalence for FA was 10.86% (0.5 SE) for nursing; general practice 21.70% (0.7 SE) and for paediatrics 16.96% (0.7 SE). FA/professional ratios for the different professional categories were: 101.07 (5.0 SE) for nursing, 239.74 (9.0 SE) for general practice and 159.54 (9.8 SE) for paediatrics. A major part of primary health care users make a high number of consultations. From this group, women overuse nursing and general practitioner services more compared to men. A higher prevalence of FAs was observed in smaller settings, in rural areas. Although taking the FAs:professional ratio as the bar, medium-size practices are more highly overused.

    2008-06-01

    To describe the Norwegian system for handling suspected drugged driving cases according to an impairment-based law, with primary focus on benzodiazepines (BZDs), blood concentrations and combination with other psychoactive compounds. Routines for handling suspected driving under the influence of drugs other than alcohol are described. These include primary police investigation, blood sampling, and clinical tests of impairment performed by a police physician, a standard analytical program covering the most relevant illegal drugs and medicines relevant to traffic safety (approximately 25 compounds), and expert witness statements prepared for the court. The drug use patterns, blood drug concentrations, and frequency of multi-drug use have been recorded, with primary focus on benzodiazepines (BZDs). Use of BZDs among apprehended drivers has been compared with patient prescriptions recorded for the same BZDs. One or more drugs have been detected in approximately 80% of the cases received for analysis every year. BZDs have been the most prevalent drugs and have been detected in 38-57% of the cases, which is more frequent than other common illegal drugs; e.g., tetrahydrocannabinol (THC; 30-43%) and amphetamine (33-39%). The majority of the BZDs have been detected at supratherapeutic blood concentrations and frequently in combination with illegal drugs, other psychoactive medicines, or alcohol. Less than 5% of the BZDs (except for nitrazepam - 7.6%) have been found to be the only drug present at therapeutic blood levels. The majority of the drivers were 20-39 years old (median age 29-33), while the majority of BZDs prescribed were to users over 50 years of age. Drivers with BZD detected are probably not representative of ordinary patients with BZD prescriptions, as shown by the age disparity of drivers and patients. The frequent detection of BZDs suggests that these compounds should be included in the analytical program used for blood samples from apprehended drivers and

  2. Cannabis consumption patterns among frequent consumers in Uruguay.

    2016-08-01

    In 2013, Uruguay became the first country to fully regulate the cannabis market, which now operates under state control. Cannabis can be legally acquired in three ways: growing it for personal use (self-cultivation), cannabis club membership, and from pharmacies (not yet implemented). Users must be entered into a confidential official registry to gain access. This article presents findings of a Respondent Driven Sample survey of 294 high-frequency cannabis consumers in the Montevideo metropolitan area. Frequent consumers resort to more than one method for acquiring cannabis, with illegal means still predominating after 1 year of the new regulation law. Cannabis users overwhelmingly support the current regulation, but many of them are reluctant to register. Some of the attitudes and behaviors of the high-frequency consumers pose a challenge to the success of the cannabis law. Individuals relying on more than one method of access defy the single access clause, a prerequisite for legal use, while the maximum amount of cannabis individuals can access monthly seems too high even for most frequent consumers, which might promote the emergence of a grey market. Reluctance to register among a significant proportion of high-frequency consumers raises doubts about the law's ability to achieve its stated objectives. Copyright © 2016 Elsevier B.V.

    Gastrocnemius tendinosis (GT) is one potential cause for posterior knee pain, commonly overlooked on clinical examinations and imaging. This study assesses the frequency of GT on MR imaging in a convenience sample based on a database search and associations with other articular pathologies and clinical findings. With IRB approval, retrospective review was completed on 300 randomly selected MR knee exams performed from February 2009 to June 2010. Following de-identification, axial T2 and sagittal PD images, with or without fat suppression, were reviewed by 2 radiologists. The gastrocnemius tendon femoral attachments were graded as normal, mild (few cysts, thickening, intermediate signal) or severe GT (multiple cysts, marrow edema, tear). Select associated MR findings of internal derangement were documented. Clinical charts were reviewed for clinical presentation, physical exam findings, and select demographics. The inter-observer reliability for presence/grading of GT was very high (kappa statistic=0.97). Frequency of GT was 50.33%, most frequently involving medial head of gastrocnemius (63.6%). Grades of GT were 41.7% and 17.2% for mild and severe respectively. Univariate analysis showed statistically significant relationship between grade of GT with arthrosis (p=0.05) and clinical joint effusion (p=0.02). Multivariate analysis showed higher odds of severe GT for individuals with medial plus lateral GT. Statistical significance was noted for presence of both GT and ACL tear (13.9%; p=0.02). Significant findings of our analysis included GT presented with predominant involvement of medial head of gastrocnemius tendon, mild in severity, strong association with ACL tear, presented frequently as posterior knee pain, limited joint motion and clinical joint effusion. However, there was no statistically significant association between demographic features and medical comorbidities in the patients. Increased understanding of frequency of GT allows more accurate reporting of

    Cannabidiol (CBD) is a naturally occurring constituent of the marijuana plant. In the past few years, there has been great interest in the therapeutic effects of isolated CBD and it is currently being explored for numerous disease conditions (e.g., pain, epilepsy, cancer, various drug dependencies). However, CBD remains a Schedule I drug on the U.S. Controlled Substances Act (CSA). Despite its status, there are no well-controlled data available regarding its abuse liability. Healthy, frequent marijuana users (n=31) were enrolled in this within subject, randomized, placebo-controlled, double-blind, multisite study that administered oral cannabidiol (0, 200, 400, 800mg) alone and in combination with smoked marijuana (0.01%, 5.3-5.8% THC). Participants received one dose combination across 8 once-weekly outpatient sessions (7.5h). The primary findings on the drug interaction effects were previously reported (Haney et al., 2016). The present study is a secondary analysis of the data to examine the abuse liability profile of oral cannabidiol (200, 400, 800mg) in comparison to oral placebo and active smoked marijuana (5.3-5.8% THC). Active marijuana reliably produced abuse-related subjective effects (e.g., high) (p0.05). Overall, CBD did not display any signals of abuse liability at the doses tested and these data may help inform U.S. regulatory decisions regarding CBD schedule on the CSA.

    Posterior reversible encephalopathy syndrome (PRES) is a serious neurological condition encountered in various medical fields. Pathophysiological factor(s) common to PRES cases of apparently unrelated etiologies are yet to be found. Based on the hypothesis that hypomagnesemia might participate in the cascade leading to PRES, our study sought to verify whether hypomagnesemia is frequently associated with PRES regardless of etiology. From a retrospective study of a cohort of 57 patients presenting with PRES of different etiologies, presented here are the findings of 19 patients with available serum magnesium levels (SMLs) during PRES. In the acute phase of PRES, hypomagnesemia was present in all 19 patients in spite of differences in etiology (including immunosuppressive drugs, hypertensive encephalopathy, eclampsia, systemic lupus erythematosus, iatrogenic etiology and unknown). SMLs were within normal ranges prior to PRES and below normal ranges during the first 48h of PRES, with a significant decrease in SMLs during the acute phase. In this retrospective study, constant hypomagnesemia was observed during the acute phase of PRES regardless of its etiology. These results now require larger studies to assess the particular importance of acute hypomagnesemia in PRES and especially the possible need to treat PRES with magnesium sulfate.

A perspectiva sociohistórica de Vigotsky fundamentou teoricamente a maioria dos estudos, sobretudos aqueles dedicados à educação de surdos. A população alvo mais estudada foi a de alunos com deficiência intelectual, seguida da surdez, sobretudo no período de 1996 a 2000; estudos dedicados a outras deficiências - física, visual e múltipla - foram menos frequentes. Os estudos descritivos, privilegiando dados qualitativos, envolvendo estudos de caso e etnográficos constituíram a maioria dos trabalhos. Os trabalhos experimentais englobaram delineamentos de grupo e delineamentos intrassujeito. Os estudos foram eloquentes em mostrar a necessidade de o professor observar mais o processo de aprendizagem do que o produto da mesma e a enfatizar o papel essencial da mediação.

    We hypothesized that the insensitivity of the electrocardiogram (ECG) in identifying acute circumflex occlusion would result in differences in the distribution of the infarct related artery (IRA) between patients with non ST elevation myocardial infarction (NSTEMI) and ST elevation myocardial infarction (STEMI) enrolled in the Occluded Artery Trial. We also sought to evaluate the impact of percutaneous intervention to the IRA on clinical outcomes for patients with NSTEMI. Overall NSTEMI subjects comprised 13% (n=283) of the trial population. The circumflex IRA was overrepresented in the NSTEMI group compared to patients enrolled with STEMI (42.5 vs. 11.2%; pCHF) (22.3 vs. 20.23%, p=0.51, HR 1.20; 0.59-2.43); as well as the individual endpoints of Death (13.8 vs. 17.0%, p=0.51, HR 0.81;0.36-1.85); MI (6.1 vs. 5.1%, p=0.84, HR=1.11; 0.28-4.41); Class IV CHF (6.7 vs. 6.0%, p=0.45, HR 1.50;0.37-6.02). There was no interaction between MI type by ECG and treatment effect (p= NS). In conclusion the occluded circumflex IRA is overrepresented in the NSTEMI population. Consistent with the overall trial results, stable patients with NSTEMI and a totally occluded IRA did not benefit from randomization to PCI. PMID:23351464

    Full Text Available The urgency of the problem of frequently ill children is associated with a significant number of patients who can be assigned to this category. Objective: to present the nosological and etiological structure of diseases in frequently ill children depending on age.Subjects and methods. 243 children aged 1 to 17 years with recurrent respiratory infections were followed up. The children were examined using routine clinical, laboratory, and instrumental examinations. The etiological diagnosisincluded bacteriological examination of the upperrespiratory tract microflora; determination of IgM and IgG antibodies against Chlamydophila pneumoniae, Mycoplasma pneumoniae, Epstein–Barr virus(EBV, and cytomegalovirus(CMV in blood by enzyme immunoassay and that of Chlamydia and Mycoplasma DNA in pharyngealswabs and that of CMV, EBV and human herpesvirustype 6 DNA in blood by polymerase chain reaction.Results. Recurrentrespiratory diseases were found to be associated with herpesvirusinfection in 75% of the children aged 1 to 6 years, with Streptococcus, Mycoplasma, and Chlamydia infections in 16, 10, and 4% of those aged 3 to 6 years, respectively, and to be accompanied by abnormal lymphoid tissue proliferation in 84% of the children aged 3 to 6 years, with the abundant growth of bacterial opportunistic pathogensin one half of the patients. Despite the continuing importance of infectious agents(herpesviruses and streptococci in 29 and 20%, respectively, the chronically ill school-aged children displayed a high incidence of somatic diseases: chronic tonsillitis (43% and chronic sinusitis (14% in children aged older than 12 years and allergic rhinitis (23% in those aged 7 to 17 years. The symptoms of autonomic vascular dystonia were observed in 21% of the patients; cardiac arrhythmias were diagnosed in 14%.

    2015-05-01

    It is now widely known that children with severe intellectual disability show a 'floor effect' on the Wechsler scales. This effect emerges because the practice of transforming raw scores into scaled scores eliminates any variability present in participants with low intellectual ability and because intelligence quotient (IQ) scores are limited insofar as they do not measure scores lower than 40. Following Hessl et al.'s results, the present authors propose a method for the computation of the Wechsler Intelligence Scale for Children--4th Ed. (WISC-IV)'s IQ and Indexes in intellectually disabled participants affected by a floored pattern of results. The Italian standardization sample (n = 2200) for the WISC-IV was used. The method presented in this study highlights the limits of the 'floor effect' of the WISC-IV in children with serious intellectual disability who present a profile with weighted scores of 1 in all the subtests despite some variability in the raw scores. Such method eliminates the floor effect of the scale and therefore makes it possible to analyse the strengths and weaknesses of the WISC-IV's Indexes in these participants. The Authors reflect on clinical utility of this method and on the meaning of raw score of 0 on subtest. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Obesity development during psychotropic treatments represents a major health issue in psychiatry. Melanin-concentrating hormone receptor 2 (MCHR2) is a central receptor involved in energy homeostasis. MCHR2 shares its promoter region with MCHR2-AS1, a long antisense non-coding RNA. The aim of this study was to determine whether tagging single nucleotide polymorphisms (tSNPs) of MCHR2 and MCHR2-AS1 are associated with the body mass index (BMI) in the psychiatric and in the general population. The influence of MCHR2 and MCHR2-AS1 tSNPs on BMI was firstly investigated in a discovery psychiatric sample (n1 = 474). Positive results were tested for replication in two other psychiatric samples (n2 = 164, n3 = 178) and in two population-based samples (CoLaus, n4 = 5409; GIANT, n5 = 113809). In the discovery sample, TT carriers of rs7754794C>T had 1.08 kg/m2 (p = 0.04) lower BMI as compared to C-allele carriers. This observation was replicated in an independent psychiatric sample (-2.18 kg/m2; p = 0.009). The association of rs7754794C>T and BMI seemed stronger in subjects younger than 45 years (median of age). In the population-based sample, a moderate association was observed (-0.17 kg/m2; p = 0.02) among younger individuals (influence of MCHR2 and/or MCHR2-AS1 on obesity in psychiatric patients and on the pathophysiology of atypical depression.

    Exacerbation frequency is central in treatment strategies for chronic obstructive pulmonary disease. However, whether chronic obstructive pulmonary disease patients from the general population with frequent exacerbations continue to have frequent exacerbations over an extended period of time...... is currently unknown. In this study, we aimed to investigate the stability of the frequent exacerbator in a population-based setting. To this end, we conducted a nationwide register-based descriptive study with a 10-year follow-up period of chronic obstructive pulmonary disease patients with at least one...... medically treated exacerbation in 2003. Each subsequent year, we divided the population into frequent, infrequent and non-exacerbators and quantified the flow between categories. Further, we estimated the percentage of frequent exacerbators at baseline who stayed in this category each year during a 5-year...

    Full Text Available Homelessness, HIV, and substance use are interwoven problems. Furthermore, homeless individuals are frequent users of emergency services. The main purpose of this study was to identify risk factors for frequent emergency room (ER visits and to examine the effects of housing status and HIV serostatus on ER utilization. The second purpose was to identify risk factors for frequent ER visits in patients with a history of illicit drug use.A retrospective analysis was performed on 412 patients enrolled in a Boston-based health care for the homeless program (HCH. This study population was selected as a 2:1 HIV seronegative versus HIV seropositive match based on age, sex, and housing status. A subgroup analysis was performed on 287 patients with history of illicit drug use. Chart data were analyzed to compare demographics, health characteristics, and health service utilization. Results were stratified by housing status. Logistic models using generalized estimating equations were used to predict frequent ER visits.In homeless patients, hepatitis C was the only predictor of frequent ER visits (OR 4.49, p<0.01. HIV seropositivity was not predictive of frequent ER visits. In patients with history of illicit drug use, mental health (OR 2.53, 95% CI 1.07-5.95 and hepatitis C (OR 2.85, 95% CI 1.37-5.93 were predictors of frequent ER use. HIV seropositivity did not predict ER use (OR 0.45, 95% CI 0.21 - 0.97.In a HCH population, hepatitis C predicted frequent ER visits in homeless patients. HIV seropositivity did not predict frequent ER visits, likely because HIV seropositive HCH patients are engaged in care. In patients with history of illicit drug use, hepatitis C and mental health disorders predicted frequent ER visits. Supportive housing for patients with mental health disorders and hepatitis C may help prevent unnecessary ER visits in this population.

    Understanding feedbacks between terrestrial and atmospheric systems is vital for predicting the consequences of global change, particularly in the rapidly changing Arctic. Fire is a key process in this context, but the consequences of altered fire regimes in tundra ecosystems are rarely considered, largely because tundra fires occur infrequently on the modern landscape. We present paleoecological data that indicate frequent tundra fires in northcentral Alaska between 14,000 and 10,000 years ago. Charcoal and pollen from lake sediments reveal that ancient birchdominated shrub tundra burned as often as modern boreal forests in the region, every 144 years on average (+/- 90 s.d.; n = 44). Although paleoclimate interpretations and data from modern tundra fires suggest that increased burning was aided by low effective moisture, vegetation cover clearly played a critical role in facilitating the paleo-fires by creating an abundance of fine fuels. These records suggest that greater fire activity will likely accompany temperature-related increases in shrub-dominated tundra predicted for the 21st century and beyond. Increased tundra burning will have broad impacts on physical and biological systems as well as land-atmosphere interactions in the Arctic, including the potential to release stored organic carbon to the atmosphere.

    Enterocytozoon bieneusi (phylum Microsporidia) is a human pathogen with a broad host range. Following the sequencing of 3.8 Mb of the estimated 6-Mb E. bieneusi genome, simple sequence repeats (micro- and minisatellites) were identified. Sequencing of four such repeats from various human and animal E. bieneusi isolates identified extensive sequence polymorphism and enabled the development of a multilocus genotyping method to study the epidemiology of this pathogen. We genotyped E. bieneusi DNA extracted from 197 fecal samples originating from children with diarrhea who were residing in Kampala, Uganda. Three newly identified microsatellite markers and the internal transcribed spacer were PCR amplified, and multiple cloned amplicons for each marker were sequenced from each individual. Most microsatellite sequences were unique to the Ugandan population. Significantly, polymorphism not only was present among isolates but was also found within isolates. This observation suggests that infections with heterogeneous E. bieneusi populations are common in this region. However, the data do not exclude that some of the polymorphism originates from divergent paralogs within the genome. The frequent occurrence of multiple sequences within an isolate precluded the identification of multilocus genotypes. This observation raises the possibility that in a region in which the prevalence of E. bieneusi is high, sequencing of uncloned PCR products may not be adequate for multilocus genotyping.

    To screen patients with frequently relapsing nephrotic syndrome (FRNS) for the presence of ambulatory hypertension and left ventricular hypertrophy. Following ethical and parental approvals, consecutive patients with FRNS of ≥2 y duration were enrolled. Those with estimated glomerular filtration rate ambulatory blood pressure was recorded by Spacelab 90207; echocardiography was done for left ventricular mass. Ambulatory hypertension was defined as the presence of clinic blood pressure >95th centile for age, sex and height, and systolic blood pressure load exceeding 25 %. Of 99 patients, 73 were boys; their median (IQR) age was 120 (84-156) mo. Clinic blood pressure was >95th percentile in 63 (63.6 %) patients. Ambulatory hypertension was present in 33 (33.3 %), including 14 patients with severe hypertension; 16 (16.1 %) had masked hypertension and 30 (30.3 %) had white coat hypertension. Non-dipping was seen in 72 and 55 patients had high nocturnal systolic blood pressure load. Of 21 patients with increased left ventricular mass index, 9 (42.9 %) had ambulatory hypertension, 3 (14.3 %) had masked hypertension and 6 (28.6 %) patients had white coat hypertension. Compared to those with normal blood pressure, patients with ambulatory hypertension were younger at onset of nephrotic syndrome (odds ratio, OR 0.94; 95 % CI 0.91-0.98; P = 0.002), longer duration of frequently relapsing disease (OR 1.05; 95 % CI 1.00-1.10; P = 0.034) and higher body mass index (BMI) (OR 1.61; 95 % CI 1.07-4.40; P = 0.020). BMI was positively correlated with 24-h systolic blood pressure load (r = 0.23; P = 0.002) and with the left ventricular mass index (r = 0. 57; P = 0.001). Many patients with FRNS showed high prevalence of clinic, ambulatory and white coat hypertension, emphasizing the need to carefully screen these patients in order to ensure their appropriate management. While clinic blood pressure monitoring detects most patients with hypertension, it

    Given the extent, magnitude and functional significance of the neurocognitive deficits of schizophrenia, growing attention has been paid recently to patients' self-awareness of their own deficits. Thus far, the literature has shown either that patients fail to recognize their cognitive deficits or that the association between subjective and objective cognition is weak in schizophrenia. The reasons for this lack of consistency remain unexplained but may have to do, among others, with the influence of potential confounding clinical variables and the choice of the scale used to measure self-awareness of cognitive deficits. In the current study, we sought to examine the relationships between subjective and objective cognitive performance in schizophrenia, while controlling for the influence of sociodemographic and psychiatric variables. Eighty-two patients with a schizophrenia-spectrum disorder (DSM-IV criteria) were recruited. Patients' subjective cognitive complaints were evaluated with the Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS), the most frequently used scale to measure self-awareness of cognitive deficits in schizophrenia. Neurocognition was evaluated with working memory, planning and visual learning tasks taken from Cambridge Neuropsychological Tests Automated Battery. The Stroop Color-Word test was also administered. Psychiatric symptoms were evaluated with the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia. The relationships between subjective and objective cognition were evaluated with multivariate hierarchic linear regression analyses, taking into consideration potential confounders such as sociodemographic and psychiatric variables. Finally, a factor analysis of the SSTICS was performed. For the SSTICS total score, the regression analysis produced a model including two predictors, namely visual learning and Stoop interference performance, explaining a moderate portion of the variance

    To determine the efficacy of a 14-day regimen of esomeprazole 20 mg for the treatment of frequent heartburn in subjects who are likely to self-treat with over-the-counter medications without consulting a health care provider. Adults with frequent heartburn ≥ 2 days per week in the past 4 weeks were randomly assigned to 14-day double-blind treatment with esomeprazole 20 mg once daily or placebo in 2 identical multicenter studies (ClinicalTrials.gov identifiers: NCT01370525, NCT01370538). The primary efficacy outcome was percentage of heartburn-free 24-hour days across 14 days. Secondary efficacy outcomes included heartburn resolution, defined as heartburn ≤ 2 days over 14 days, and percentages of subjects reporting ≤ 1 day with heartburn in the first and final weeks of treatment. Subjects recorded data in daily self-assessment diaries. The percentage of heartburn-free 24-hour days over 14 days was significantly higher (P esomeprazole 20 mg compared with placebo in study 1 (N = 331; 46.13% vs. 33.07%, respectively) and study 2 (N = 320; 48.00% vs 32.75%, respectively). Significantly more subjects treated with esomeprazole 20 mg had heartburn resolution over 14 days and in the first and final weeks compared with placebo. Within the first 4 days, the proportion of subjects with heartburn-free days was significantly greater with esomeprazole 20 mg versus placebo. Treatment was generally well tolerated, with a safety pattern consistent with the known profile for esomeprazole. A 14-day regimen of esomeprazole 20 mg once daily was effective for treating frequent heartburn in subjects who are likely to self-treat with over-the-counter medications.

    Full Text Available Objective. Frequent insufficient sleep, defined as ≥14 days/past 30 days in which an adult did not get enough rest or sleep, is associated with adverse mental and physical health outcomes. Little is known about the prevalence of frequent insufficient sleep among American Indians/Alaska Natives (AI/AN. Methods. We assessed racial/ethnic differences in the prevalence of frequent insufficient sleep from the combined 2009-2010 Behavioral Risk Factor Surveillance Survey among 810,168 respondents who self-identified as non-Hispanic white (NHW, , non-Hispanic black (NHB, , Hispanic (, or AI/AN (. Results. We found significantly higher unadjusted prevalences (95% CI of frequent insufficient sleep among AI/AN (34.2% [32.1–36.4] compared to NHW (27.4% [27.1–27.6]. However, the age-adjusted excess prevalence of frequent insufficient sleep in AI/AN compared to NHW was decreased but remained significant with the addition of sex, education, and employment status; this latter relationship was further attenuated by the separate additions of obesity and lifestyle indicators, but was no longer significant with the addition of frequent mental distress to the model (PR  =  1.05; 95% CI : 0.99–1.13. This is the first report of a high prevalence of frequent insufficient sleep among AI/AN. These results further suggest that investigation of sleep health interventions addressing frequent mental distress may benefit AI/AN populations.

    Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

    The term pediatric autoimmune enteropathy was originally applied to a form of intractable diarrhea seen in children under the age of 6 months and characterized by male predominance, concurrent autoimmune-associated disorders, circulating gut autoantibodies, a lack of severe immunodeficiency and small bowel atrophy with prominent crypt apoptosis. However, recent studies have cast doubt over the specific clinicopathologic findings associated with this entity. We, therefore, collected 178 gastrointestinal biopsies from 14 patients and examined their clinical, serologic and pathologic findings. Patients at presentation ranged in age from birth to 15.9 years (median, 5.5 months; mean, 4.1 years) and included six males and eight females. All children suffered from chronic watery diarrhea and malnutrition. Concomitant-associated disorders were noted in 11 (79%) cases and included 10 (71%) with an immunodeficiency disorder and/or another autoimmune-related disease. Eleven patients (79%) were positive for anti-enterocyte antibodies. The salient findings of autoimmune enteropathy were most prominent in the small intestines and the majority (79%) of patients demonstrated villous blunting, crypt hyperplasia, mononuclear cell inflammatory expansion of the lamina propria and crypt apoptosis. The remaining (21%) patients showed marked intraepithelial lymphocytosis reminiscent of celiac disease. Further, acute cryptitis and crypt abscesses were seen in seven (50%) patients obscuring the presence of apoptosis. The absence of Paneth cells, goblet cells or both was noted in seven (50%) patients. Follow-up information was available for all patients with 13 (93%) receiving immunosuppressant therapy and demonstrating partial-to-complete response. In total, three patients died from continued diarrhea and sepsis with one decedent before treatment could be initiated. In summary, autoimmune enteropathy in children is a heterogenous disease with protean clinical and pathologic findings

    Full Text Available Abstract Background People use emergency department services for a wide variety of health complaints, many of which could be handled outside hospitals. Many frequent readmissions are due to problems with chronic disease and are preventable. We postulated that patient related factors such as the type of condition, demographic factors, access to alternative services outside hospitals and patient preference for hospital or non-hospital services would influence readmissions for chronic disease. This study aimed to explore the link between frequent readmissions in chronic disease and these patient related factors. Methods A retrospective analysis was performed on emergency department data collected from a regional hospital in NSW Australia in 2008. Frequently readmitted patients were defined as those with three or more admissions in a year. Clinical, service usage and demographic patient characteristics were examined for their influence on readmissions using multivariate analysis. Results The emergency department received about 20,000 presentations a year involving some 16,000 patients. Most patients (80% presented only once. In 2008 one hundred and forty four patients were readmitted three or more times in a year. About 20% of all presentations resulted in an admission. Frequently readmitted patients were more likely to be older, have an urgent Triage classification, present with an unplanned returned visit and have a diagnosis of neurosis, chronic obstructive pulmonary disease, dyspnoea or chronic heart failure. The chronic ambulatory care sensitive conditions were strongly associated with frequent readmissions. Frequent readmissions were unrelated to gender, time, day or season of presentation or country of birth. Conclusions Multivariate analysis of routinely collected hospital data identified that the factors associated with frequent readmission include the type of condition, urgency, unplanned return visit and age.

    2017-05-01

    Full Text Available Acute calcific tendinopathy is one of the manifestations of hydroxyapatite crystal deposition disease. While it is more frequent in the shoulder, it has been described in virtually all areas of the body, but rarely in the muscles of the hand. Its etiopathogenesis is not yet fully understood and despite being a fairly frequent condition, it is commonly misdiagnosed. The onset of the disease is usually acute and resolves spontaneously. Acute calcific tendinitis of the interosseous tendons of the hand is an uncommon site of a frequent condition. The clinical presentation is similar to other entities, thus errors in diagnosis frequently occur, resulting in over-treatment or unnecessary tests. We describe a case of acute calcific tendinitis of the interosseous muscles of the hand with a brief review of the current literature with emphasis on diagnostic imaging methods.

    The examination of operation quality for high-frequent operation requires other approaches than the typical evaluation of punctuality (trains on time) and reliability (operated trains). This is because passengers in high-frequent railway systems do not necessarily notice train delays as they just...... take the first train in their direction. The article examines four different approaches to examine operation quality for high-frequent operation that are based on the experiences of the passengers. These approaches are the service frequency of the operation, travel time extension, a combination...... operation simulation software. Combining the passenger delay model with simulation software gives the possibility to forecast future infrastructure and operation scenarios which make it possible to improve the planning....

    This study examines whether a woman's mental health is associated with use of contraception. We used national data from 2004 and 2006 to calculate the prevalence of contraceptive use among women with frequent mental distress. We examined associations among mental distress and permanent contraception and any highly or moderately effective, reversible contraceptive method. Women with (86%) and without (87%) frequent mental distress reported using contraception, but contraceptive type varied by mental distress and income. Among women who use contraception, those with frequent mental distress had 1.4 times higher odds (95% CI: 1.2-1.6) of using permanent contraception. Among lower income women who use reversible contraception, those with frequent mental distress had lower odds of using highly [adjusted odds ratio (aOR)=0.5, 95% CI: 0.4-0.8] and moderately (aOR=0.6, 95% CI: 0.4-0.9) effective methods than less effective methods. Contraceptive providers should consider mental health when providing counseling about contraception. Published by Elsevier Inc.

  4. GRAMI: Generalized Frequent Subgraph Mining in Large Graphs

    KAUST Repository

    El Saeedy, Mohammed El Sayed

    2011-07-24

    Mining frequent subgraphs is an important operation on graphs. Most existing work assumes a database of many small graphs, but modern applications, such as social networks, citation graphs or protein-protein interaction in bioinformatics, are modeled as a single large graph. Interesting interactions in such applications may be transitive (e.g., friend of a friend). Existing methods, however, search for frequent isomorphic (i.e., exact match) subgraphs and cannot discover many useful patterns. In this paper we propose GRAMI, a framework that generalizes frequent subgraph mining in a large single graph. GRAMI discovers frequent patterns. A pattern is a graph where edges are generalized to distance-constrained paths. Depending on the definition of the distance function, many instantiations of the framework are possible. Both directed and undirected graphs, as well as multiple labels per vertex, are supported. We developed an efficient implementation of the framework that models the frequency resolution phase as a constraint satisfaction problem, in order to avoid the costly enumeration of all instances of each pattern in the graph. We also implemented CGRAMI, a version that supports structural and semantic constraints; and AGRAMI, an approximate version that supports very large graphs. Our experiments on real data demonstrate that our framework is up to 3 orders of magnitude faster and discovers more interesting patterns than existing approaches.

  8. Spatiotemporal Frequent Pattern Discovery from Solar Event Metadata

    Science.gov (United States)

    Aydin, B.; Angryk, R.; Filali Boubrahimi, S.; Hamdi, S. M.

    2016-12-01

    Solar physics researchers entered the big data era with the launch of NASA's Solar Dynamics Observatory (SDO) mission, which captures approximately 60,000 high-resolution images every day and generates 0.55 petabytes of raster data each year. The big data trend in solar data is anticipated to be sustained by the ground-based DKIST telescope, which is expected to generate three to five petabytes of data each year. Many software modules continuously work on SDO's image data to detect spatial boundaries of solar events. Recently, a solar event tracking algorithm and interpolation methodologies have been proposed for creating large-scale solar event vector data sets in GSU's Data Mining Lab. The solar event tracking algorithm utilizes the spatial locations and corresponding image parameters for linking the polygon-based instances; therefore, creates spatiotemporal trajectory objects with extended geometric representations. Thus, we can access and make use of vector-based solar event metadata, which is in the form of continuously evolving region trajectories. Spatial and temporal patterns such as co-occurrences, sequences, periodicity and convergences frequently transpire among solar event instances. Here, we will concentrate on spatiotemporal co-occurrences and event sequences. Spatiotemporal co-occurrences are the spatial and temporal overlap among two or more solar event instances. On the other hand, spatiotemporal event sequences appear among the events that are temporally following each other and spatially in close-by locations. Our study includes approximately 120,000 trajectory-based instances of seven solar event types (Active Regions, Coronal Holes, Emerging Flux, Filaments, Flares, Sigmoids, and Sunspots) that occurred between January 2012 and December 2014. The tracked solar events are interpolated at each 10-minute interval. We will present the results of our spatiotemporal co-occurrence pattern mining and spatiotemporal event sequence mining algorithms

  9. Positive selection results in frequent reversible amino acid replacements in the G protein gene of human respiratory syncytial virus.

    Directory of Open Access Journals (Sweden)

    Viviane F Botosso

    2009-01-01

    Full Text Available Human respiratory syncytial virus (HRSV is the major cause of lower respiratory tract infections in children under 5 years of age and the elderly, causing annual disease outbreaks during the fall and winter. Multiple lineages of the HRSVA and HRSVB serotypes co-circulate within a single outbreak and display a strongly temporal pattern of genetic variation, with a replacement of dominant genotypes occurring during consecutive years. In the present study we utilized phylogenetic methods to detect and map sites subject to adaptive evolution in the G protein of HRSVA and HRSVB. A total of 29 and 23 amino acid sites were found to be putatively positively selected in HRSVA and HRSVB, respectively. Several of these sites defined genotypes and lineages within genotypes in both groups, and correlated well with epitopes previously described in group A. Remarkably, 18 of these positively selected tended to revert in time to a previous codon state, producing a "flip-flop" phylogenetic pattern. Such frequent evolutionary reversals in HRSV are indicative of a combination of frequent positive selection, reflecting the changing immune status of the human population, and a limited repertoire of functionally viable amino acids at specific amino acid sites.

  10. Finding frequent trajectories by clustering and sequential pattern mining

    Directory of Open Access Journals (Sweden)

    Arthur A. Shaw

    2014-12-01

    Full Text Available Data mining is a powerful emerging technology that helps to extract hidden information from a huge volume of historical data. This paper is concerned with finding the frequent trajectories of moving objects in spatio-temporal data by a novel method adopting the concepts of clustering and sequential pattern mining. The algorithms used logically split the trajectory span area into clusters and then apply the k-means algorithm over this clusters until the squared error minimizes. The new method applies the threshold to obtain active clusters and arranges them in descending order based on number of trajectories passing through. From these active clusters, inter cluster patterns are found by a sequential pattern mining technique. The process is repeated until all the active clusters are linked. The clusters thus linked in sequence are the frequent trajectories. A set of experiments conducted using real datasets shows that the proposed method is relatively five times better than the existing ones. A comparison is made with the results of other algorithms and their variation is analyzed by statistical methods. Further, tests of significance are conducted with ANOVA to find the efficient threshold value for the optimum plot of frequent trajectories. The results are analyzed and found to be superior than the existing ones. This approach may be of relevance in finding alternate paths in busy networks (congestion control, finding the frequent paths of migratory birds, or even to predict the next level of pattern characteristics in case of time series data with minor alterations and finding the frequent path of balls in certain games.

    Science.gov (United States)

    Nichols, H J; Cant, M A; Hoffman, J I; Sanderson, J L

    2014-12-01

    As breeding between relatives often results in inbreeding depression, inbreeding avoidance is widespread in the animal kingdom. However, inbreeding avoidance may entail fitness costs. For example, dispersal away from relatives may reduce survival. How these conflicting selection pressures are resolved is challenging to investigate, but theoretical models predict that inbreeding should occur frequently in some systems. Despite this, few studies have found evidence of regular incest in mammals, even in social species where relatives are spatio-temporally clustered and opportunities for inbreeding frequently arise. We used genetic parentage assignments together with relatedness data to quantify inbreeding rates in a wild population of banded mongooses, a cooperatively breeding carnivore. We show that females regularly conceive to close relatives, including fathers and brothers. We suggest that the costs of inbreeding avoidance may sometimes outweigh the benefits, even in cooperatively breeding species where strong within-group incest avoidance is considered to be the norm.

  17. Incremental Frequent Subgraph Mining on Large Evolving Graphs

    KAUST Repository

    Abdelhamid, Ehab

    2017-08-22

    Frequent subgraph mining is a core graph operation used in many domains, such as graph data management and knowledge exploration, bioinformatics and security. Most existing techniques target static graphs. However, modern applications, such as social networks, utilize large evolving graphs. Mining these graphs using existing techniques is infeasible, due to the high computational cost. In this paper, we propose IncGM+, a fast incremental approach for continuous frequent subgraph mining problem on a single large evolving graph. We adapt the notion of “fringe” to the graph context, that is the set of subgraphs on the border between frequent and infrequent subgraphs. IncGM+ maintains fringe subgraphs and exploits them to prune the search space. To boost the efficiency, we propose an efficient index structure to maintain selected embeddings with minimal memory overhead. These embeddings are utilized to avoid redundant expensive subgraph isomorphism operations. Moreover, the proposed system supports batch updates. Using large real-world graphs, we experimentally verify that IncGM+ outperforms existing methods by up to three orders of magnitude, scales to much larger graphs and consumes less memory.

    Hereditary motor and sensory neuropathy type Russe (HMSNR), also called CMT4G, is an autosomal recessive inherited peripheral neuropathy (IPN) caused by a founder mutation in the HK1 gene. HMSNR affects only patients with Roma origin, similar to the better known HMSN type Lom clarified earlier. By testing IPN patients with Roma origin, we realized that HMSNR affects surprisingly many patients in the Czech Republic. HMSNR is one of the most frequent types of IPN in this country and appears to be twice more frequent than HMSNL. Pronounced lower limb atrophies and severe deformities often lead to walking inability in even young patients, but hands are usually only mildly affected even after many years of disease duration. The group of 20 patients with HMSNR presented here is the first report about the prevalence of HMSNR from central Europe. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2014-01-01

    Mining frequent subgraphs is an important operation on graphs; it is defined as finding all subgraphs that appear frequently in a database according to a given frequency threshold. Most existing work assumes a database of many small graphs, but modern applications, such as social networks, citation graphs, or proteinprotein interactions in bioinformatics, are modeled as a single large graph. In this paper we present GRAMI, a novel framework for frequent subgraph mining in a single large graph. GRAMI undertakes a novel approach that only finds the minimal set of instances to satisfy the frequency threshold and avoids the costly enumeration of all instances required by previous approaches. We accompany our approach with a heuristic and optimizations that significantly improve performance. Additionally, we present an extension of GRAMI that mines frequent patterns. Compared to subgraphs, patterns offer a more powerful version of matching that captures transitive interactions between graph nodes (like friend of a friend) which are very common in modern applications. Finally, we present CGRAMI, a version supporting structural and semantic constraints, and AGRAMI, an approximate version producing results with no false positives. Our experiments on real data demonstrate that our framework is up to 2 orders of magnitude faster and discovers more interesting patterns than existing approaches. 2014 VLDB Endowment.

  3. Extremely frequent behavior in consumer research: theory and empirical evidence for chronic casino gambling.

    2009-09-01

    The present study informs understanding of customer segmentation strategies by extending Twedt's heavy-half propositions to include a segment of users that represent less than 2% of all households-consumers demonstrating extremely frequent behavior (EFB). Extremely frequent behavior (EFB) theory provides testable propositions relating to the observation that few (2%) consumers in many product and service categories constitute more than 25% of the frequency of product or service use. Using casino gambling as an example for testing EFB theory, an analysis of national survey data shows that extremely frequent casino gamblers do exist and that less than 2% of all casino gamblers are responsible for nearly 25% of all casino gambling usage. Approximately 14% of extremely frequent casino users have very low-household income, suggesting somewhat paradoxical consumption patterns (where do very low-income users find the money to gamble so frequently?). Understanding the differences light, heavy, and extreme users and non-users can help marketers and policymakers identify and exploit "blue ocean" opportunities (Kim and Mauborgne, Blue ocean strategy, Harvard Business School Press, Boston, 2005), for example, creating effective strategies to convert extreme users into non-users or non-users into new users.

  6. The Moderating Effect of Frequent Singing on Voice Aging.

    2017-01-01

    The effects of aging on voice production are well documented, including changes in loudness, pitch, and voice quality. However, one important and clinically relevant question that remains concerns the possibility that the aging of voice can be prevented or at least delayed through noninvasive methods. Indeed, discovering natural means to preserve the integrity of the human voice throughout aging could have a major impact on the quality of life of elderly adults. The objective of this study was therefore to examine the potentially positive effect of singing on voice production. To this aim, a group of 72 healthy nonsmoking adults (20-93 years old) was recruited and separated into three groups based on their singing habits. Several voice parameters were assessed (fundamental frequency [f0] mean, f0 standard deviation [SD], f0 minimum and f0 maximum, mean amplitude and amplitude SD, jitter, shimmer, and harmonic-to-noise ratio) during the sustained production of vowel /a/. Other parameters were assessed during standardized reading passage (speaking f0, speaking f0 SD). As was expected, age effects were found on most acoustic parameters with significant sex differences. Importantly, moderation analyses revealed that frequent singing moderates the effect of aging on most acoustic parameters. Specifically, in frequent singers, there was no decrease in the stability of pitch and amplitude with age, suggesting that the voice of frequent singers remains more stable in aging than the voice of non-singers, and more generally, providing empirical evidence for a positive effect of singing on voice in aging.

    Full Text Available The effect of frequent examinations on the students' learning has had inconsistent results. This study aimed to assess the effectiveness of frequent announced quizzes on the learning of a representative sample of Iranian medical students.This experimental study was conducted among 37 fifth semester medical students who had taken the course in Protozoology and Helminthology, in which the same basic information were provided about different types of protozoa and worms. Initially, in the teaching of helminthology, ten routine sessions were handled with lectures and interactive questions and answers. Then at the beginning of the protozoology topic in the beginning of all of the next 9 sessions, the students were informed that they will have a quiz at the end of each session. At the end of the semester, the total scores of quizzes were compared with the mean final scores of protozoology and helminthology using paired t and repeated measure tests.The mean final scores of the protozoology lesson were not significantly different from that of the helminthology (10.45 ± 2.75 vs.11.25 ± 2.56 on the scale of 20, respectively, P=0.13. There was no significant difference in the mean score of the five quizzes compared with the mean final term score of protozoology. The overall mean scores in the helminthology lesson (11.25±2.56, protozoology lesson (10.45±2.75, and the quizzes (9.16 ± 3.55 were significantly different (P <0.0001.Frequent announced quizzes were not effective on increasing the medical students' motivation and learning.

  10. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Directory of Open Access Journals (Sweden)

    Rashmika Pandya

    2011-02-01

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other. 

  11. Analyzing the Number of Varieties in Frequently Found Flows

    Abnormal traffic that causes various problems on the Internet, such as P2P flows, DDoS attacks, and Internet worms, is increasing; therefore, the importance of methods that identify and control abnormal traffic is also increasing. Though the application of frequent-itemset-mining techniques is a promising way to analyze Internet traffic, the huge amount of data on the Internet prevents such techniques from being effective. To overcome this problem, we have developed a simple frequent-itemset-mining method that uses only a small amount of memory but is effective even with the large volumes of data associated with broadband Internet traffic. Using our method also involves analyzing the number of distinct elements in the itemsets found, which helps identify abnormal traffic. We used a cache-based implementation of our method to analyze actual data on the Internet and demonstrated that such an implementation can be used to provide on-line analysis of data while using only a small amount of memory.

  12. New techniques for mining frequent patterns in unordered trees.

    Zhang, Sen; Du, Zhihui; Wang, Jason T L

    2015-06-01

    We consider a new tree mining problem that aims to discover restrictedly embedded subtree patterns from a set of rooted labeled unordered trees. We study the properties of a canonical form of unordered trees, and develop new Apriori-based techniques to generate all candidate subtrees level by level through two efficient rightmost expansion operations: 1) pairwise joining and 2) leg attachment. Next, we show that restrictedly embedded subtree detection can be achieved by calculating the restricted edit distance between a candidate subtree and a data tree. These techniques are then integrated into an efficient algorithm, named frequent restrictedly embedded subtree miner (FRESTM), to solve the tree mining problem at hand. The correctness of the FRESTM algorithm is proved and the time and space complexities of the algorithm are discussed. Experimental results on synthetic and real-world data demonstrate the effectiveness of the proposed approach.

    2015-06-01

    Full Text Available Nasopharyngeal carcinoma is a rare malignancy of childhood having different epidemiological, histopathological and clinical characteristics. The most frequent histopathological type is undifferentiated nasopharyngeal carcinoma and is associated with advanced locoregional disease and distant metastasis in childhood. Because of high incidence of systemic disease in childhood, chemotherapy is the first choice in treatment of advanced disease. Although 5 year's survival rates have reached 70% with combined therapy modalities, late complications continue to be major problem. Parallel to improvement in the diagnostic skills and therapy, there is an increase in survivors of childhood cancer. Since late effects of cancer therapy can be encountered more often, closer follow-up of nasopharyngeal carcinoma patients who are under serious treatment schemes is an obligation.

    Baker's asthma and rhinitis are among the most frequent occupational respiratory disorders. The aim of the study was to evaluate the frequency of work-related symptoms and the clinical relevance of sensitization to allergens in screened and symptomatic bakers. Eighty-nine bakers participating in a screening study and 104 bakers filing a claim for compensation were examined with regard to occupational and clinical case history, lung function parameters, and sensitization to bakery allergens by skin prick tests, specific IgE analyses, and inhalative challenge tests. A high prevalence of respiratory disorders, abnormal lung function parameters, and sensitization to bakery allergens exists. Most frequently, bakers with workplace-related respiratory symptoms showed sensitization to wheat flour (64%), rye flour (52%), soy bean flour (25%), and alpha-amylase (21%). The correlation between these sensitizations and asthma case history and inhalative challenge test responses was significant. However, approximately 29% of the bakers with respiratory symptoms showed no sensitization to these bakery allergens, whereas 32% of the sensitized bakers in the screening group had no workplace-related symptoms. Atopic status defined by skin prick test sensitization to common allergens or elevated total IgE levels was found to be a risk factor for the development of sensitization to bakery allergens and respiratory symptoms. On the other hand, there is evidence for an increased frequency of elevated total IgE as the result of occupational allergen exposure because respective findings were observed in bakers without symptoms. Sensitization to bakery allergens seems to be the main cause of baker's asthma and rhinitis but cannot explain the asthma case history in each case. Further methods are required to objectively assume irritative pathomechanisms. Our findings indicate the necessity for an improved primary prevention of exposure to inhalative noxae in bakeries.

  19. Finding Neural Assemblies with Frequent Item Set Mining

    Directory of Open Access Journals (Sweden)

    David ePicado-Muiño

    2013-05-01

    Full Text Available Cell assemblies, defined as groups of neurons exhibiting precise spike coordination, were proposed as a model of network processing in the cortex. Considerable progress made in recent years in multi-electrode technology enables to record massively parallel spike trains of hundred(s of neurons. Nevertheless, due to the challenges inherent in multivariate approaches, most studies favoring cortical cell assemblies still resorted to analyzing pairwise interactions. However, to recoverthe underlying correlation structures, higher-order correlations need to be identified directly. Inspired by the Accretion method (Gerstein et al. 1978 we propose a new assembly detection method based on frequent item set mining (FIM, which searches effectively and without redundancy for individual spike patterns that exceed a given support threshold. We study search methods, with which the space of potential cell assemblies may be explored, as well as test statistics and subsetconditions with which candidate assemblies may be assessed and filtered. It turns out that a core challenge of assembly detection is multiple testing, which causes a large number of false discoveries. Unfortunately, criteria that address individual candidate assemblies and try to assess them with statistical tests and/or subset conditions do not help much to tackle this problem. The core idea of our method is to shift the focus of statistical testing from specific assemblies (consisting of a specific set of neurons to spike patterns of a certain size (i.e. with a certain number of neurons. This significantly reduces the number of necessary tests, thus alleviating the multiple testing problem. We demonstrate that our method is able to reliably suppress false discoveries, while it is still very sensitive in discovering synchronous activity. Since we exploit high-speed computational techniques from frequent item set mining (FIM for the tests, our method is also computationally efficient.

    To describe the characteristics of frequent users of hospital emergency departments and analyze whether characteristics varied in relation to how revisits were distributed over the course of the year studied. Retrospective study of patients over the age of 14 years who were treated in a hospital emergency department at least 10 times in 2013. Patients were identified in 17 public hospitals in the Spanish autonomous community of Madrid. Data related to the first and successive visits were gathered and analyzed by quarter year. We included 2340 patients with a mean (SD) age of 54 (21) years. A total of 1361 (58.%) were women, 1160 (50%) had no concomitant diseases, 1366 (58.2%) were substance abusers, and 25 (1.1%) were homeless. During the first visit, 2038 (87.1%) complained of a recent health problem, and 289 (12.4%) were admitted. Sixty (2.6%) patients concentrated their revisits in a single quarters 335 (14.3%) in 2 quarters, 914 (39.1%) in 3, and 1005 (42.9%) in 4. Patients whose revisits were distributed over more quarters were older (> 65 years), had more concomitant conditions, were on more medications (P < .001), showed cognitive impairment (P = .039), and were more functionally dependent (P = .007). They were also more likely to have been hospitalized on the first visit (P < .001). Patients whose revisits were concentrated in fewer quarters were more often women (P = .012) and more likely to have a specific diagnosis (P < .001) and revisit for a reason related to the initial visit (P = .012). Our study shows that the frequent user has specific characteristics and loyally comes to the same emergency department over the course of a year. Patients whose revisits are dispersed over a longer period have more complex problems and use more resources during their initial visit.

    Δ9-Tetrahydrocannabinol (THC), the primary psychoactive constituent in cannabis, impairs psychomotor performance, cognition and driving ability; thus, driving under the influence of cannabis is a public safety concern. We documented cannabis' psychomotor, neurocognitive, subjective and physiological effects in occasional and frequent smokers to investigate potential differences between these smokers. Fourteen frequent (≥4x/week) and 11 occasional (cannabis smokers entered a secure research unit ∼19 h prior to smoking one 6.8% THC cigarette. Cognitive and psychomotor performance was evaluated with the critical tracking (CTT), divided attention (DAT), n-back (working memory) and Balloon Analog Risk (BART) (risk-taking) tasks at -1.75, 1.5, 3.5, 5.5 and 22.5 h after starting smoking. GLM (General Linear Model) repeated measures ANOVA was utilized to compare scores. Occasional smokers had significantly more difficulty compensating for CTT tracking error compared with frequent smokers 1.5 h after smoking. Divided attention performance declined significantly especially in occasional smokers, with session × group effects for tracking error, hits, false alarms and reaction time. Cannabis smoking did not elicit session × group effects on the n-back or BART. Controlled cannabis smoking impaired psychomotor function, more so in occasional smokers, suggesting some tolerance to psychomotor impairment in frequent users. These data have implications for cannabis-associated impairment in driving under the influence of cannabis cases. Published by Oxford University Press 2015.

    2017-01-01

    Full Text Available Data mining techniques are applied to identify hidden patterns in large amounts of patient data. These patterns can assist physicians in making more accurate diagnosis. For different physical conditions of patients, the same physiological index corresponds to a different symptom association probability for each patient. Data mining technologies based on certain data cannot be directly applied to these patients’ data. Patient data are sensitive data. An adversary with sufficient background information can make use of the patterns mined from uncertain medical data to obtain the sensitive information of patients. In this paper, a new algorithm is presented to determine the top K most frequent itemsets from uncertain medical data and to protect data privacy. Based on traditional algorithms for mining frequent itemsets from uncertain data, our algorithm applies sparse vector algorithm and the Laplace mechanism to ensure differential privacy for the top K most frequent itemsets for uncertain medical data and the expected supports of these frequent itemsets. We prove that our algorithm can guarantee differential privacy in theory. Moreover, we carry out experiments with four real-world scenario datasets and two synthetic datasets. The experimental results demonstrate the performance of our algorithm.

    Full Text Available There are numerous neuropsychological tests for assessing executive functions in aging, which vary according to the different domains assessed. OBJECTIVE: To present a systematic review of the most frequently used instruments for assessing executive functions in older adults with different educational levels in clinical and experimental research. METHODS: We searched for articles published in the last five years, using the PubMed database with the following terms: "neuropsychological tests", "executive functions", and "mild cognitive impairment". There was no language restriction. RESULTS: 25 articles fulfilled all the inclusion criteria. The seven neuropsychological tests most frequently used to evaluate executive functions in aging were: [1] Trail Making Test (TMT Form B; [2] Verbal Fluency Test (VFT - F, A and S; [3] VFT Animals category; [4] Clock Drawing Test (CDT; [5] Digits Forward and Backward subtests (WAIS-R or WAIS-III; [6] Stroop Test; and [7] Wisconsin Card Sorting Test (WCST and its variants. The domains of executive functions most frequently assessed were: mental flexibility, verbal fluency, planning, working memory, and inhibitory control. CONCLUSION: The study identified the tests and domains of executive functions most frequently used in the last five years by research groups worldwide to evaluate older adults. These results can direct future research and help build evaluation protocols for assessing executive functions, taking into account the different educational levels and socio-demographic profiles of older adults in Brazil.

    The understanding of various health-oriented vital sign data generated from body sensor networks (BSNs) and discovery of the associations between the generated parameters is an important task that may assist and promote important decision making in healthcare. For example, in a smart home scenario where occupants' health status is continuously monitored remotely, it is essential to provide the required assistance when an unusual or critical situation is detected in their vital sign data. In this paper, we present an efficient approach for mining the periodic patterns obtained from BSN data. In addition, we employ a correlation test on the generated patterns and introduce productive-associated periodic-frequent patterns as the set of correlated periodic-frequent items. The combination of these measures has the advantage of empowering healthcare providers and patients to raise the quality of diagnosis as well as improve treatment and smart care, especially for elderly people in smart homes. We develop an efficient algorithm named PPFP-growth (Productive Periodic-Frequent Pattern-growth) to discover all productive-associated periodic frequent patterns using these measures. PPFP-growth is efficient and the productiveness measure removes uncorrelated periodic items. An experimental evaluation on synthetic and real datasets shows the efficiency of the proposed PPFP-growth algorithm, which can filter a huge number of periodic patterns to reveal only the correlated ones.

    Lawson, Anton E.

    Niaz (1990) presents arguments in favor of the retention of Piaget's epistemic subject as a theoretical construct to guide research and practice in science education and psychology. The intent of this article is to point out the weaknesses of those arguments and to suggest that the weight of evidence argues against the existence of the logical thinker postulated by Piaget. Therefore, contrary to Niaz's conclusion that the acceptance of Piaget's epistemic subject will facilitate the development of cognitive theories with greater explanatory power, the conclusion is reached that Piaget's epistemic subject is dead and that continued acceptance of this aspect of Piagetian theory would be counterproductive.

    2014-01-01

    Full Text Available Objectives: To compare the level of conjunctival changes using conjunctival impression cytology in wearers of frequent replacement hydrogel (FRHL and frequent replacement silicone hydrogel contact lens FRSHL. Materials and Methods: Forty-two contact lens users who were seen at the Cornea and Contact Lens Unit, Department of Ophthalmology, Dokuz Eylül University were evaluated in this study. The first group consisted of wearers of FRHL used for minimum one year and maximum five years. The second group consisted of wearers who used FRSHL for minimum one year and maximum 5 years. Twenty healthy individuals with no contact lens history were included in the control group. Conjunctival impression cytology was applied to all contact lens users and the control group in order to evaluate the conjunctival changes, and the results of impression cytology were graded by the Nelson’s method. Results: In the comparison of the groups according to impression cytology scoring, there was no difference between the users of FRHL and FRSHL. Similar amounts of squamous metaplasia and goblet cell loss were encountered in both groups. Nonetheless, impression cytology grading was significantly lower in the control group than in the other two groups. Conclusion: In conclusion, the use of FRHL and FRSHL for over a year causes some histological changes in the conjunctiva such as squamous metaplasia and goblet cell loss eventually leading to dry eye symptoms. However, no differences were determined between FRHL and FRSHL users with regard to severity of conjunctival changes. (Turk J Ophthalmol 2014; 44: 47-52

    Full Text Available Polypoid melanoma represents a distinct variant of melanoma characterized by an ulcerated exophytic nodule. Although this melanocytic tumor is usually restricted to the papillary dermis, it presents with a thick Breslow level and aggressive course. Its rapidly growing vertical phase and its amelanotic nature frequently simulate benign or non-aggressive entities; leading to a delay in biopsy and resulting in an increased risk of metastasis at the time of the diagnosis.

    2015-01-01

    Full Text Available Introduction: Psychogenic non-epileptic seizures represent a paroxysmal event followed by a sudden change of behavior, cognition or consciousness, mostly of short duration, which resemble or can be understood as epileptic seizures. They occur in persons without epilepsy and in patients with epilepsy. They are not associated with abnormal EEG discharges because their cause is a psychic disorder. Case report: A 20-year-old patient has been suffering of occasional 'morning short-lasting jerking hand movements, staring and fainting' since the age of 14 years. Beside a symptomatic anamnesis for epilepsy and non-specifically changed standard EEG, antiepileptic therapy (valproate and lamotrigine was introduced. Because of non-response to antiepileptic therapy, the patient was forwarded for further clinical examination involving video EEG telemetry, which indicated that this was a case of psychogenic non-epileptic seizures. A successive withdrawal of antiepileptic drugs was initiated, and also, a psychologist and psychiatrist were included into treatment, which resulted in the reduction of seizures and improvement of the patient's general condition. Conclusion: Psychogenic non-epileptic seizures represent a frequent diagnostic problem requiring team's work, while the video EEG telemetry is the method of choice for diagnosis.

    Full Text Available Causal illusions occur when people perceive a causal relation between two events that are actually unrelated. One factor that has been shown to promote these mistaken beliefs is the outcome probability. Thus, people tend to overestimate the strength of a causal relation when the potential consequence (i.e. the outcome occurs with a high probability (outcome-density bias. Given that children and adults differ in several important features involved in causal judgment, including prior knowledge and basic cognitive skills, developmental studies can be considered an outstanding approach to detect and further explore the psychological processes and mechanisms underlying this bias. However, the outcome density bias has been mainly explored in adulthood, and no previous evidence for this bias has been reported in children. Thus, the purpose of this study was to extend outcome-density bias research to childhood. In two experiments, children between 6 and 8 years old were exposed to two similar setups, both showing a non-contingent relation between the potential cause and the outcome. These two scenarios differed only in the probability of the outcome, which could either be high or low. Children judged the relation between the two events to be stronger in the high probability of the outcome setting, revealing that, like adults, they develop causal illusions when the outcome is frequent.

    To clarify the semiology of febrile seizures (FS) and to determine the frequency of FS with symptoms suggestive of focal onset. FS symptoms in children were reported within 24h of seizure onset by the parents using a structured questionnaire consisting principally of closed-ended questions. We focused on events at seizure commencement, including changes in behavior and facial expression, and ocular and oral symptoms. We also investigated the autonomic and motor symptoms developing during seizures. The presence or absence of focal and limbic features was determined for each patient. The associations of certain focal and limbic features with patient characteristics were assessed. Information was obtained on FS in 106 children. Various events were recorded at seizure commencement. Behavioral changes were observed in 35 children, changes in facial expression in 53, ocular symptoms in 78, and oral symptoms in 90. In terms of events during seizures, autonomic symptoms were recognized in 78, and convulsive motor symptoms were recognized in 68 children. Focal features were evident in 81 children; 38 children had two or more such features. Limbic features were observed in 44 children, 9 of whom had two or more such features. There was no significant relationship between any patient characteristic and the numbers of focal or limbic features. The semiology of FS varied widely among children, and symptoms suggestive of focal onset were frequent. FS of focal onset may be more common than is generally thought. Copyright © 2017 Elsevier Inc.

    2017-09-01

    The aim of this review is to describe predictors and therapeutic principles for PVC-induced cardiomyopathy. PVC-induced cardiomyopathy is a treatable condition resulting in a reversible form of cardiomyopathy. PVC-induced cardiomyopathy has only recently been recognized as an entity that causes a reversible form of cardiomyopathy. The mechanism of development of PVC-induced cardiomyopathy has not yet been elucidated, although dyssynchrony appears to play a major role. Multiple factors have been described that are independently associated with PVC-induced cardiomyopathy. Predictors of PVC-induced cardiomyopathy include PVC prevalence, epicardial origin, male gender, longer symptom duration and asymptomatic status, presence of interpolated PVCs, lack of circadian variability, and a broader PVC-QRS width. In the presence of cardiomyopathy, work-up for structural heart disease and its etiology should be performed, followed by aggressive attempts at PVC reduction. There is evidence that ablation therapy is superior to medical therapy for frequent PVCs, but treatment decisions need to be individualized depending on the patients symptoms, PVC prevalence, PVC origin, patients comorbidities, and patient preference. The potential of sudden cardiac death associated with the presence of structural heart disease needs to be recognized, and appropriate risk stratification is mandatory.

    Full Text Available Chest pain is one of the most frequent patient’s complaints. The commonest underlying causes are well known, but, sometimes, in some clinical scenarios, it is necessary to consider other diagnoses. We report a case of a 68-year-old Caucasian male, chronically hypertensive, who complained of recurrent episodes of chest pain and fever with elevated acute phase reactants. The first investigation was negative for some of the most likely diagnosis and he quickly improved with anti-inflammatory drugs. Over a few months, his symptoms continued to recur periodically, his hypertension was aggravated, and he developed headaches and lower limbs claudication. After a temporal artery biopsy that was negative for vasculitis, he underwent a positron emission tomography suggestive of Takayasu Arteritis. Takayasu Arteritis is a rare chronic granulomatous vasculitis of the aorta and its first-order branches affecting mostly females up to 50 years old. Chest pain is experienced by >40% of the patients and results from the inflammation of the aorta, pulmonary artery, or coronaries.

    Full Text Available Reports of HIV-1 superinfection (re-infection have demonstrated that the immune response generated against one strain of HIV-1 does not always protect against other strains. However, studies to determine the incidence of HIV-1 superinfection have yielded conflicting results. Furthermore, few studies have attempted to identify superinfection cases occurring more than a year after initial infection, a time when HIV-1-specific immune responses would be most likely to have developed. We screened a cohort of high-risk Kenyan women for HIV-1 superinfection by comparing partial gag and envelope sequences over a 5-y period beginning at primary infection. Among 36 individuals, we detected seven cases of superinfection, including cases in which both viruses belonged to the same HIV-1 subtype, subtype A. In five of these cases, the superinfecting strain was detected in only one of the two genome regions examined, suggesting that recombination frequently occurs following HIV-1 superinfection. In addition, we found that superinfection occurred throughout the course of the first infection: during acute infection in two cases, between 1-2 y after infection in three cases, and as late as 5 y after infection in two cases. Our results indicate that superinfection commonly occurs after the immune response against the initial infection has had time to develop and mature. Implications from HIV-1 superinfection cases, in which natural re-exposure leads to re-infection, will need to be considered in developing strategies for eliciting protective immunity to HIV-1.

    Wrestling normally places extreme demands on the body and thus may cause various kinds of injuries. An in-depth understanding of the episodes of injured sites, types, timings, and treatment modalities would help participants be aware of wrestling-related injury occurrences so as to develop effective preventive measures. Therefore, this study aims to investigate the gender-specific injuries among elite wrestling athletes. Subjects were selected from the 2009 Taiwanese National Wrestling Sport Championship. Participants were adolescent wrestling athletes, ages 16-18, who must have received at least one bronze medal at national level tournaments in 2008. A total of 118 respondents, 96 males and 22 females, completed and returned the questionnaire in which demographic data and information about the types, sites, and timings of injuries suffered and treatment modalities adopted were elicited. The data were analyzed with independent t-tests. The questionnaire results revealed a significantly higher injury rate for males than for females. The top three injured sites for males were waist (11.1%), ankle joint (10.1%) and finger (9.6%); while for females were ankle joint (13.6%), knee (12.5%) and waist (11.3%). Contusions were the most frequent type of injury: for males (73.5%) and for females (70.6%); followed by tendon inflammation for males (10.7%) and accumulated injuries for females (15.2%). During training and matching periods, the frequency of injuries for males (69.0%) is lower than that for females (81.8%). Traditional Chinese medicine (TCM) with acupuncture and moxibustion was the most common treatment modalities used for males (51.8%) and for females (68.0%); followed by orthopedics: for males (29.5%) and for females (18.0%). The present study contributed as the first effort to reveal the potency of using TCM with acupuncture and moxibustion in wrestling competitions. To prevent possible brain and body injuries in wrestling, safety education, skills and rules, and

    Attributions regarding alcohol treatment research protocols influencing clinical outcomes have persisted for more than 25 years. Although well-designed alcohol treatment outcome studies typically involve frequent, and often comprehensive, research assessment protocols, procedures are seldom in place to control or account for possible subject reactivity to the research protocol. This article presents a theoretical basis for a relationship between research protocols and treatment outcomes. The article reviews the relevant alcohol treatment outcome literature and presents a "weight of evidence" regarding subject reactivity effects and alcohol treatment outcome research assessment protocols. Also, the FRAMES (feedback, responsibility, advice, menu, empathy and self-efficacy) model was coupled with self-regulation theory to provide a theoretical explanation of how research assessment protocols might contribute to clinically relevant behavioral change. Researcher attributions, empirical investigations and theoretical considerations all provide evidence that is consistent with the existence of subject reactivity to research assessment protocols. Recommendations are made regarding interpretation of data collected as part of an alcohol treatment outcome study, control of potential subject reactivity confounding variables and directions for future research.

    Oral fluid (OF) is an alternative biological matrix for monitoring cannabis intake in drug testing, and drugged driving (DUID) programs, but OF cannabinoid test interpretation is challenging. Controlled cannabinoid administration studies provide a scientific database for interpreting cannabinoid OF tests. We compared differences in OF cannabinoid concentrations from 19 h before to 30 h after smoking a 6.8% THC cigarette in chronic frequent and occasional cannabis smokers. OF was collected with the Statsure Saliva Sampler™ OF device. 2D-GC-MS was used to quantify cannabinoids in 357 OF specimens; 65 had inadequate OF volume within 3 h after smoking. All OF specimens were THC-positive for up to 13.5 h after smoking, without significant differences between frequent and occasional smokers over 30 h. Cannabidiol (CBD) and cannabinol (CBN) had short median last detection times (2.5-4 h for CBD and 6-8 h for CBN) in both groups. THCCOOH was detected in 25 and 212 occasional and frequent smokers' OF samples, respectively. THCCOOH provided longer detection windows than THC in all frequent smokers. As THCCOOH is not present in cannabis smoke, its presence in OF minimizes the potential for false positive results from passive environmental smoke exposure, and can identify oral THC ingestion, while OF THC cannot. THC ≥ 1 μg/L, in addition to CBD ≥ 1 μg/L or CBN ≥ 1 μg/L suggested recent cannabis intake (≤13.5 h), important for DUID cases, whereas THC ≥ 1 μg/L or THC ≥ 2 μg/L cutoffs had longer detection windows (≥30 h), important for workplace testing. THCCOOH windows of detection for chronic, frequent cannabis smokers extended beyond 30 h, while they were shorter (0-24 h) for occasional cannabis smokers.

  5. Knowing and not knowing: A frequent human arrangement.

    The paradigmatic system of societal abuse occurs in totalitarian state systems. The relational systems of subjugation that maintain such states of terror must, of necessity, destroy any authentic civic space in which individuals can flourish. Similar dynamics characterize child abuse within families. Survival requires the use of varied strategies, the most extreme of which are dissociative in nature, and that result in marked distortions of developmental trajectories across all psychological domains. Such dynamics are mirrored in dissociative systems that, in the absence of intervention, perpetuate the trauma of non-recognition by subjugation and self-objectification, or by omnipotent denial of others' subjectivity. All abusive systems are facilitated by bystanders, whose awareness of what is disavowed is always partial, resulting in a state of knowing and not-knowing. As dynamics shift, bystanders may behave like victims-passive, helpless, frightened and frozen, or like perpetrators-taking vicarious and voyeuristic pleasure in abuse or actively aiding and abetting the abusers.

  6. Finding neural assemblies with frequent item set mining

    Cell assemblies, defined as groups of neurons exhibiting precise spike coordination, were proposed as a model of network processing in the cortex. Fortunately, in recent years considerable progress has been made in multi-electrode recordings, which enable recording massively parallel spike trains of hundred(s) of neurons simultaneously. However, due to the challenges inherent in multivariate approaches, most studies in favor of cortical cell assemblies still resorted to analyzing pairwise interactions. However, to recover the underlying correlation structures, higher-order correlations need to be identified directly. Inspired by the Accretion method proposed by Gerstein et al. (1978) we propose a new assembly detection method based on frequent item set mining (FIM). In contrast to Accretion, FIM searches effectively and without redundancy for individual spike patterns that exceed a given support threshold. We study different search methods, with which the space of potential cell assemblies may be explored, as well as different test statistics and subset conditions with which candidate assemblies may be assessed and filtered. It turns out that a core challenge of cell assembly detection is the problem of multiple testing, which causes a large number of false discoveries. Unfortunately, criteria that address individual candidate assemblies and try to assess them with statistical tests and/or subset conditions do not help much to tackle this problem. The core idea of our new method is that in order to cope with the multiple testing problem one has to shift the focus of statistical testing from specific assemblies (consisting of a specific set of neurons) to spike patterns of a certain size (i.e., with a certain number of neurons). This significantly reduces the number of necessary tests, thus alleviating the multiple testing problem. We demonstrate that our method is able to reliably suppress false discoveries, while it is still very sensitive in discovering

  7. A population model of chaparral vegetation response to frequent wildfires.

    The recent increase in wildfire frequency in the Santa Monica Mountains (SMM) may substantially impact plant community structure. Species of Chaparral shrubs represent the dominant vegetation type in the SMM. These species can be divided into three life history types according to their response to wildfires. Nonsprouting species are completely killed by fire and reproduce by seeds that germinate in response to a fire cue, obligate sprouting species survive by resprouting from dormant buds in a root crown because their seeds are destroyed by fire, and facultative sprouting species recover after fire both by seeds and resprouts. Based on these assumptions, we developed a set of nonlinear difference equations to model each life history type. These models can be used to predict species survivorship under varying fire return intervals. For example, frequent fires can lead to localized extinction of nonsprouting species such as Ceanothus megacarpus while several facultative sprouting species such as Ceanothus spinosus and Malosma (Rhus) laurina will persist as documented by a longitudinal study in a biological preserve in the SMM. We estimated appropriate parameter values for several chaparral species using 25 years of data and explored parameter relationships that lead to equilibrium populations. We conclude by looking at the survival strategies of these three species of chaparral shrubs under varying fire return intervals and predict changes in plant community structure under fire intervals of short return. In particular, our model predicts that an average fire return interval of greater than 12 years is required for 50 % of the initial Ceanothus megacarpus population and 25 % of the initial Ceanothus spinosus population to survive. In contrast, we predict that the Malosma laurina population will have 90 % survivorship for an average fire return interval of at least 6 years.

    We investigated the liver transplantation literature since 1975 and found the most frequently cited 100 articles and assessed the distribution of authors and journals of these articles. Using the advanced mode of the Institute for Scientific Information (ISI) Web of Science (WOS) search engine, the words "SU = transplantation AND TI = liver OR SU = transplantation AND TS = liver" were used to scan articles and determine the most-cited 100 articles on July 18, 2016. From 1975 to date, it appears a total of 43,369 articles were published in the field of liver transplantation in the WOS. Although the most cited article had 677 citations, the least cited article had 180 citations. The mean citation number for the 100 articles was 252.31 ± 96.75. The mean annual citation number for the articles varied from 61.55 to 5 and the mean was 15.31 ± 8.63. The most cited article was by Feng et al "Characteristics Associated With Liver Graft Failure: The Concept of a Donor Risk Index" published in the American Journal of Transplantation (677 citations). Bibliometric analysis highlights the key topics and publications that have shaped the understanding and management of liver transplantation. According to our research, this is the first study to investigate articles with most citations in the field of liver transplantation. In our study the article with the most citations was cited 677 times, whereas the 100th article was cited 180 times with a mean citation number for the 100 articles of 252.31 ± 96.75.

    Following up on two earlier publications showing increased psychological stress and psychosocial effects of travel on the business travellers this study investigated the health of spouses of business travellers. Medical claims of spouses of Washington DC World Bank staff participating in the medical insurance programme in 1997-8 were reviewed. Only the first of each diagnosis with the ninth revision of the international classification of diseases (ICD-9) recorded for each person was included in this analysis. The claims were grouped into 28 diagnostic categories and subcategories. There were almost twice as many women as men among the 4630 identified spouses. Overall, male and female spouses of travellers filed claims for medical treatment at about a 16% higher rate than spouses of non-travellers. As hypothesised, a higher rate for psychological treatment was found in the spouses of international business travellers compared with non-travellers (men standardised rate ratios (RR)=1.55; women RR=1.37). For stress related psychological disorders the rates tripled for both female and male spouses of frequent travellers (>or= four missions/year) compared with those of non-travelling employees. An increased rate of claims among spouses of travellers versus non-travellers was also found for treatment for certain other diagnostic groups. Of these, diseases of the skin (men RR=2.93; women RR=1.41) and intestinal diseases (men RR=1.31; women RR=1.47) may have some association with the spouses' travel, whereas others, such as malignant neoplasms (men RR=1.97; women RR=0.79) are less likely to have such a relation. The previously identified pattern of increased psychological disorders among business travellers is mirrored among their spouses. This finding underscores the permeable boundary between family relations and working life which earlier studies suggested, and it emphasises the need for concern within institutions and strategies for prevention.

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

However, there are no epidemiological data concerning this postural disorder. Defined by a posterior position of the centre of mass with respect to the base of support, backward disequilibrium is abnormal postural behavior, usually characterized by a posterior trunk tilt in standing and sitting positions, which predisposes subjects to backward falls. Many afflictions whether they are somatic (degenerative, ischemic and traumatic brain lesions, psychosomatic (psychomotor disadaptation syndrome, confinement to bed, nonuse situations or psychological (depression can cause backward disequilibrium. A vicious circle of falls, and loss of autonomy can arise and this is the main consequence of backward disequilibrium. Thus, in this paper, we review backward disequilibrium in elderly subjects with regard to the causes, consequences, assessment, and management.Keywords: backward disequilibrium, balance, elderly subject, falls, posture

    Graves' disease is the most common cause of hyperthyroidism in iodine-replete areas. Although progress has been made in our understanding of the pathogenesis of the disease, no treatment targeting pathogenic mechanisms of the disease is presently available. Therapies for Graves' hyperthyroidism are largely imperfect because they are bound to either a high rate of relapsing hyperthyroidism (antithyroid drugs) or lifelong hypothyroidism (radioiodine treatment or thyroidectomy). Aim of the present article is to offer a practical guidance to the reader by providing evidence-based answers to frequently asked questions in clinical practice.

    This study aims to investigate the prevalence of obesity and overweight and their association with lipid parameters in bipolar patients. Our study included 130 patients with bipolar disorder and 130 control subjects aged respectively 37.9 +/- 12.1 and 37.2 +/- 13.1 years. Obesity was evaluated by body mass index (BMI). Concentrations of total cholesterol, triglycerides, cLDL and cHDL were determined by enzymatic methods and ApoA1, ApoB and Lp(a) by techniques immunoturbidimetric. The prevalence of obesity in patients is 30.1% vs 12.3% in controls. A significant increase in BMI was noted in patients compared with controls regardless of sex and tobacco status and in patients aged less than 35 years and those consumers of alcohol. The majority of obese and overweight patients are treated with valproic acid. We found increase in cholesterol (4.41 +/- 1.02 vs 3.90 +/- 0.98 mmol/L), in cLDL (2.13 +/- 1.09 vs 1.29 +/- 0.56 mmol/L) and in Lp(a) (236 +/- 207 vs 163 +/- 150 mg/L) and decrease in HDLc (0.98 +/- 0.28 vs 1.09 +/- 0.36 mmol/L), more frequent at the obese patients and those presenting an overweight. In conclusion, in bipolar patients, obesity and overweight are frequent and associated with perturbations in lipid profile particularly an increase in total cholesterol, cLDL and Lp(a) and decrease in cHDL that increase the risk of cardiovascular disease.

    Worldwide, acute leukemia is the most common type of childhood cancer. It is particularly common in the Hispanic populations residing in the United States, Costa Rica, and Mexico City. The objective of this study was to determine the incidence of acute leukemia in children who were diagnosed and treated in public hospitals in Mexico City. Included in this study were those children, under 15 years of age and residents of Mexico City, who were diagnosed in 2006 and 2007 with leukemia, as determined by using the International Classification of Childhood Cancer. The average annual incidence rates (AAIR), and the standardized average annual incidence rates (SAAIR) per million children were calculated. We calculated crude, age- and sex-specific incidence rates and adjusted for age by the direct method with the world population as standard. We determined if there were a correlation between the incidence of acute leukemias in the various boroughs of Mexico City and either the number of agricultural hectares, the average number of persons per household, or the municipal human development index for Mexico (used as a reference of socio-economic level). Although a total of 610 new cases of leukemia were registered during 2006-2007, only 228 fit the criteria for inclusion in this study. The overall SAAIR was 57.6 per million children (95% CI, 46.9-68.3); acute lymphoblastic leukemia (ALL) was the most frequent type of leukemia, constituting 85.1% of the cases (SAAIR: 49.5 per million), followed by acute myeloblastic leukemia at 12.3% (SAAIR: 6.9 per million), and chronic myeloid leukemia at 1.7% (SAAIR: 0.9 per million). The 1-4 years age group had the highest SAAIR for ALL (77.7 per million). For cases of ALL, 73.2% had precursor B-cell immunophenotype (SAAIR: 35.8 per million) and 12.4% had T-cell immunophenotype (SAAIR 6.3 per million). The peak ages for ALL were 2-6 years and 8-10 years. More than half the children (58.8%) were classified as high risk. There was a positive

    Excessive exposure to high-salt foods may change the taste perception, which results in the overconsumption of sodium. The present study aimed to investigate the effects of liking or frequent eating of high-salt food on salt taste perception among schoolchildren. The detection threshold of sodium chloride (NaCl) and the preferred salinity of beansprout soup were determined and were used to represent the salt taste acuity and preference, respectively, of 70 Koreans aged 12-13 years. A self-administered questionnaire was used to obtain information regarding food preferences or frequency of eating certain high-salt Korean dishes, Westernised fast foods and commercially-prepared foods, as well as various food groups. The significance of differences in taste perceptions was assessed in relation to the reported liking, and frequency of eating, high-salt foods. In addition, the correlation between taste perception and the liking or frequency of eating fast foods was also assessed. The participants who reported a liking for soup/stew had significantly higher thresholds for NaCl (P = 0.029), and frequent users of fast-food restaurants showed a preference for significantly saltier soup (P = 0.010). The preferred salinity was associated significantly with a high preference for pizza (r = 0.282, P = 0.018) or hamburgers (r = 0.305, P = 0.010) and the frequent consumption of pork cutlets (r = 0.239, P = 0.046) or hamburgers (r = 0.461, P = 0.010). The results obtained in the present study suggest that the frequent consumption of certain fast foods by young teenagers may be associated with an increased preference for salt taste. This study provides basic information for use in devising education programmes in evidence-based nutrition to reduce salt intake.

    Transitional cell carcinoma (TCC) is the most common type of bladder cancer. Here we sequenced the exomes of nine individuals with TCC and screened all the somatically mutated genes in a prevalence set of 88 additional individuals with TCC with different tumor stages and grades. In our study, we...... discovered a variety of genes previously unknown to be mutated in TCC. Notably, we identified genetic aberrations of the chromatin remodeling genes (UTX, MLL-MLL3, CREBBP-EP300, NCOR1, ARID1A and CHD6) in 59% of our 97 subjects with TCC. Of these genes, we showed UTX to be altered substantially more...... frequently in tumors of low stages and grades, highlighting its potential role in the classification and diagnosis of bladder cancer. Our results provide an overview of the genetic basis of TCC and suggest that aberration of chromatin regulation might be a hallmark of bladder cancer....

    The objective of the current experiment was to study the responses of ruminal and blood metabolites of Holstein dairy cows to propylene glycol (PG) under different methods of delivery during frequent feeding. By providing the same amount (200 mL or 200 g) of PG, delivery methods for PG were assessed: 1) control treatment: no PG; 2) dietary treatment: 200 g of PG as a dry product (65% purity; corresponded to 308 g of the dry product) mixed into the TMR; 3) oral-drench treatment: 200 mL of liquid PG (100% purity) orally drenched; and 4) rumen-drench treatment: 200 g of PG as a dry product drenched via the rumen cannula to mimic top dressing. Eight multiparous (lactation = 3 +/- 1.1 SD) ruminally cannulated Holstein dairy cows (DIM = 204 +/- 104.5 SD) were fed PG for 4 d (d 11 to 14) in a replicated 4 x 4 Latin square design with an experimental length of 14 d for each period. On the last day of each period, serial blood samples were removed from an indwelling catheter placed in the right jugular vein immediately before and for 4 h after PG administration. Cows were fed at 12x feeding/d for 2 d before entering the serial sampling period to minimize postprandial influences on blood metabolites. Ruminal content was also sampled hourly for 4 h on d 14. Milk was sampled from 2 consecutive milkings on d 13 during each period. Dry matter intake and milk yield were not affected by PG. Percentages of milk lactose were increased by PG delivered by all methods tested in the current experiment. Ruminal concentrations (as percentages of total volatile fatty acids) of acetate were decreased and concentrations of propionate and isovalerate were increased by PG, regardless of the delivery method; however, total volatile fatty acid concentration was not affected by PG. Ruminal concentrations of butyrate were decreased and concentrations of valerate were increased by PG drench, via either an oral or ruminal drench. The degree of reduction in butyrate concentration or increase in

    The syndrome of intra-vitreous bleeding in association with subarachnoid hemorrhage (SAH) was first described by the French ophthalmologist Albert Terson. In the last 10 years, 31 articles describing 202 cases of Terson's syndrome (TS) were published. Only 3 out of the 31 were printed in non-ophthalmological journals. The findings of our prospective study underline the fact that too little attention is paid to TS in the early treatment of patients with SAH. Between 1/95 and 8/97, 89 patients with spontaneous SAH (7% of all admissions) were transferred to our hospital for post acute phase rehabilitation. Out of these, 13 patients (19 eyes) could be diagnosed with TS. This corresponds to an incidence of 14.6% of all patients with SAH (previous studies: 2-27%). However, only one patient had been correctly diagnosed with TS in the referring clinic. Early recognition of TS is of high importance since diminuation of visual acuity even to functional blindness, complicated in the bilateral case, can hamper the rehabilitative process considerably. Moreover, complications can lead to significant and irreversible damage, i.e. proliferative vitreo-retinopathy (PVR), retinal breaks, traction amotio, and cataract. Suspicion of TS is raised in either cooperative patients complaining of compromised visual acuity or in patients where funduscopy shows vitreous opacity. According to our results, visual evoked potentials (VEP) have only a limited role in diagnosis because of their low sensitivity. Not infrequently, however, VEP may point to accompanying optic nerve atrophy, thereby suggesting conservative treatment. Absolute indications for surgical interventions are PVR and its sequelae; relative indications are subjective visual impairment, impediment of rehabilitation, or lack of spontaneous resorption of the hemorrhage. The surgical procedure of choice is the pars plana vitrectomy (PPV). Rare complications of this operation are retinal damage, endophthalmitis, and reoccurrence of

    This retrospective cohort study provides a descriptive analysis of a population that frequently uses an urban emergency medical service (EMS) and identifies factors that contribute to use among all frequent users. For purposes of this study we divided frequent users into the following groups: low- frequent users (4 EMS transports in 2012), medium-frequent users (5 to 6 EMS transports in 2012), high-frequent users (7 to 10 EMS transports in 2012) and super-frequent users (11 or more EMS transports in 2012). Overall, we identified 539 individuals as frequent users. For all groups of EMS frequent users (i.e. low, medium, high and super) one or more hospital admissions, receiving a referral for follow-up care upon discharge, and having no insurance were found to be statistically significant with frequent EMS use (Pstatistically significant with frequent EMS use.

    The purpose of this study was to examine the responses of normal living subjects to the application of anteroposterior forces to the ribcage. Seventeen subjects aged between 25 and 37 years were tested during slow oscillatory loading while breath-holding at the end of a normal expiration. The mean stiffness coefficient was found to be 9.4 N mm(-1) (SD 2.9) and the mean gradient of the force-strain relation was 1888 N (SD 646). Comparison with previously published cadaver data indicates that the embalmed cadaver ribcage stiffness is in the order of three times stiffer than living subjects, while fresh cadavers showed comparable stiffness to living subjects. A number of studies have used models to predict and understand the behaviour of the thoracic spine. Validation of the behaviour of models which include the thoracic spine and ribcage depends on comparison of model response predictions with observed responses of human subjects. The present study provides data on the anteroposterior compressibility of the ribcage of living subjects which may be suitable for use in model validation studies. Copyright © 1994.

Fear of falling and quality of life scores were assessed at baseline and 12-month periods.Results: 146 subjects were recruited, 116 female (79.5% with a mean age of 67.1 years. At the end of the study, 49% of participants had not fallen. All of the balancing abilities were compared between frequent and infrequent fallers and were significantly improved (P < 0.001 except for functional reach in the frequent fall group. Most subjects (72%–79% complied well with the exercise program. However, compliance had no effect on balancing abilities. About 36.4% of participants had adverse events from exercise, of which knee pain was the top ranked. The quality of life and the fall efficacy scores increased significantly at the end of the study. Factors affecting falling were compliance with exercise (adjusted odds ratio [OR]: 2.55, 95% confidence intervals [CI]: 1.04, 6.30 and a history of falling ≥3 times in the previous year (adjusted OR: 3.76, 95% CI: 1.18, 11.98.Conclusion: Performing simply-designed balancing exercises, at least 3 days per week, can increase

    A growing number of studies have identified cleaners as a group at risk for adverse health effects of the skin and the respiratory tract. Chemical substances present in cleaning products could be responsible for these effects. Currently, only limited information is available about irritant and health hazardous chemical substances found in cleaning products. We hypothesized that chemical substances present in cleaning products are known health hazardous substances that might be involved in adverse health effects of the skin and the respiratory tract. We performed a systematic review of cleaning products used in the Swiss cleaning sector. We surveyed Swiss professional cleaning companies (n = 1476) to identify the most used products (n = 105) for inclusion. Safety data sheets (SDSs) were reviewed and hazardous substances present in cleaning products were tabulated with current European and global harmonized system hazard labels. Professional cleaning products are mixtures of substances (arithmetic mean 3.5 +/- 2.8), and more than 132 different chemical substances were identified in 105 products. The main groups of chemicals were fragrances, glycol ethers, surfactants, solvents; and to a lesser extent, phosphates, salts, detergents, pH-stabilizers, acids, and bases. Up to 75% of products contained irritant (Xi), 64% harmful (Xn) and 28% corrosive (C) labeled substances. Hazards for eyes (59%) and skin (50%), and hazards by ingestion (60%) were the most reported. Cleaning products potentially give rise to simultaneous exposures to different chemical substances. As professional cleaners represent a large workforce, and cleaning products are widely used, it is a major public health issue to better understand these exposures. The list of substances provided in this study contains important information for future occupational exposure assessment studies.

    Reproducibility of subjective refraction measurement is limited by various factors. The main factors affecting reproducibility include the characteristics of the measurement method and of the subject and the examiner. This article presents the results of a study on this topic, focusing on the reproducibility of subjective refraction measurement in healthy eyes. The results of previous studies are not all presented in the same way by the respective authors and cannot be fully standardized without consulting the original scientific data. To the extent that they are comparable, the results of our study largely correspond largely with those of previous investigations: During repeated subjective refraction measurement, 95% of the deviation from the mean value was approximately ±0.2 D to ±0.65 D for the spherical equivalent and cylindrical power. The reproducibility of subjective refraction measurement in healthy eyes is limited, even under ideal conditions. Correct assessment of refraction results is only feasible after identifying individual variability. Several measurements are required. Refraction cannot be measured without a tolerance range.

    To determine the coital frequency among infertile couples and which factors are associated with less frequent coitus. Cross-sectional study. Tertiary-level male infertility clinic. A total of 1,298 infertile men. Administration of computer-based survey, semen analysis, and serum hormone evaluation. Monthly coital frequency. A total of 1,298 patients presented to clinic for infertility consultation and completed the computer-based survey. The median male age was 35 years (interquartile range [IQR] 32-39 years) and the median duration of infertility was 2 years (IQR 1-4 years) before consultation. Median monthly coital frequency was seven (IQR 5-10; range 0-40); 24% of couples were having intercourse ≤ 4 times per month. Overall, 0.6%, 2.7%, 4.8%, 5.8%, and 10.8% of the men reported having intercourse 0, 1, 2, 3, and 4 times per month, respectively. When simultaneously taking into account the influence of age, libido, erectile function, and semen volume on coital frequency, older patients had 1.05 times higher odds (per year of age) of less frequent coitus (odds ratio 1.05, 95% confidence interval 1.03-1.08). In addition, patients with better erectile function had 1.12 times higher odds (per point on Sexual Health Inventory for Men scale) of more frequent coitus (odds ratio 1.12, 95% confidence interval 1.09-1.18). Similar to the general population, most infertile couples report having coitus more than four times per month. Older male age and erectile dysfunction are independent risk factors for less frequent coitus among infertile men, which could have an impact on fertility. Coital frequency should be considered in infertility assessments. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

    In clinical practice, ultrasonography (US) often reveals, in the dorsal scan, a small anechoic area distally in both inflamed and clinically non-inflamed metacarpophalangeal joints. This "distal anechogenicity in the metacarpophalangeal joint" (DAEM) might thus be scored false positively as arthritis. We aimed to investigate whether the DAEM is a sign of arthritis. We evaluated the prevalence of DAEMs in 24 non-arthritic subjects. We then compared the dimensions of the DAEM in 10 non-arthritic subjects with a DAEM and 7 consecutive rheumatoid arthritis (RA) outpatients, using 2-D and 3-D ultrasound. Furthermore, we dissected two fresh-frozen postmortem hand specimens after US. A DAEM was observed in the metacarpophalangeal 2 (MCP2) joints of 54% of the 24 non-selected non-arthritic individuals; in none of those did the joint exhibit a power Doppler signal. A DAEM was observed in 86% of the 7 RA patients. Dimensions of DAEMs did not statistically significantly differ between these groups. At 3-D imaging and dissection, the DAEM was found to be an extension of the metacarpophalangeal joint capsule. In conclusion, DAEMs occur frequently and are not a sign of arthritis, but are distal joint recesses. This should be taken into account when using current sensitive ultrasonographic scoring systems grading arthritis. Copyright © 2014 World Federation for Ultrasound in Medicine & Biology.

    To compare patterns of healthcare service user preference between urban slums in Dhaka and adjacent rural areas and to identify key determinants of those preferences. The data were collected through baseline surveys conducted in 2008 and 2009. A total of 3207 subjects aged 10-90 years were systematically selected from 12 big slums in Dhaka and 3 rural villages outside Dhaka. Two frequently used healthcare sources utilized in 1 month preceding the baseline survey were pharmacies (slum, 42.6%; rural, 30.1%) and government hospitals/clinics (GVHC; slum, 13.5%; rural, 8.9%). According to the multilevel logistic regression analysis adjusted for age, sex and marital status, the likelihood of using pharmacies and GVHC were higher for those subjects who used non-hygienic toilets, who reported food deficiency at a family level, who expressed dissatisfaction about family income and who stated poor health status. Some more factors namely overweight, living in permanently structured house, smoking bidis and less frequency of watching TV were associated with higher likelihood of using GVHC. Pharmacy was the most dominant healthcare service in both areas. As persons running pharmacies often provide poor quality of healthcare services, they need continuous training and back-up supports to improve their quality of services and to strengthen the overall healthcare system in Bangladesh.

    A 52 year old gentleman presented with chest pain, after a long distance flight from India; he had made long haul flights every 2 weeks over the last 5 years as part of his job. His ECG revealed T wave inversion in leads V1-3. Cardiac biomarkers including troponin were negative; we proceeded to exercise stress testing (EST). This revealed 2 mm ST depression at 2 min of the standard Bruce protocol, associated with chest pain. He was taken immediately to the coronary catheterization laboratory; engagement of the left main caused pressure damping with 6 French, then 5 French diagnostic Judkins left 4 catheters. An ostial left main stenosis was seen; the right and left coronary trees otherwise had no significant stenoses. He had normal LV function. He underwent inpatient CABG 7 days later.

    In studies of operant choice, when one schedule of a concurrent pair is varied while the other is held constant, the constancy of the constant schedule may exert discriminative control over performance. In our earlier experiments, schedules varied reciprocally across components within sessions, so that while food ratio varied food rate remained constant. In the present experiment, we held one variable-interval (VI) schedule constant while varying the concurrent VI schedule within sessions. We studied five conditions, each with a different constant left VI schedule. On the right key, seven different VI schedules were presented in seven different unsignaled components. We analyzed performances at several different time scales. At the longest time scale, across conditions, behavior ratios varied with food ratios as would be expected from the generalized matching law. At shorter time scales, effects due to holding the left VI constant became more and more apparent, the shorter the time scale. In choice relations across components, preference for the left key leveled off as the right key became leaner. Interfood choice approximated strict matching for the varied right key, whereas interfood choice hardly varied at all for the constant left key. At the shortest time scale, visit patterns differed for the left and right keys. Much evidence indicated the development of a fix-and-sample pattern. In sum, the procedural difference made a large difference to performance, except for choice at the longest time scale and the fix-and-sample pattern at the shortest time scale. © Society for the Experimental Analysis of Behavior.

    Mitochondrial disorders (MIDs) frequently manifest phenotypically as epilepsy (mitochondrial epilepsy). Mitochondrial epilepsy occurs in early-onset as well as late-onset syndromic and non-syndromic MIDs. We were interested in the types of epilepsy, the prevalence of mitochondrial epilepsy, the type and effectiveness of treatment, and in the outcome of adult MID patients with epilepsy. We retrospectively evaluated adult patients with syndromic or non-syndromic MIDs and epilepsy. MIDs were classified according to the modified Walker criteria as definite, probable, and possible. Epilepsy in adult patients with a MID was classified as "structural/metabolic" in two-thirds of the cases and as "genetic" in one-third of the cases. Although all types of seizures may occur in mitochondrial epilepsy, adult patients most frequently presented with generalised tonic-clonic seizures, partial seizures, convulsive status epilepticus, or non-convulsive status epilepticus. Cerebral imaging was normal in one-third of the patients. Two-thirds of the adult patients with mitochondrial epilepsy who took antiepileptic drugs received monotherapy, one-third combination treatment. The antiepileptic drugs most frequently administered included levetiracetam, lamotrigine, valproic acid, and gabapentin. Antiepileptic drugs were usually well tolerated and the outcome favourable. Adult mitochondrial epilepsy appears to be less frequent than previously believed but the prevalence strongly depends on patient selection. Mitochondrial epilepsy is most frequently "structural/metabolic". AEDs recommended for mitochondrial epilepsy include levetiracetam, lamotrigine, gabapentin and lacosamide. The outcome of mitochondrial epilepsy may be more favourable if mitochondrion-toxic AEDs are avoided. Only if non-mitochondrion-toxic AEDs are ineffective, mitochondrion-toxic AEDs may be used.

    The male to female ratio in autism is 4:1 in the global autistic population, but increases to 23:1 in autistic subjects without physical or brain abnormalities. 1 Despite this well-recognised gender difference, male predisposition to autistic disorder remains unexplained and the role of sex chromosomes is still debated. Numerical and structural abnormalities of the sex chromosomes are among the most frequently reported chromosomal disorders associated with autism. However, genome scans have f...

    Cancer is one of the leading causes of death characterized by uncontrolled growth and spread of cancer cells. There are several hundred thousands of new cases of cancer worldwide. Clinical oncology is still challenged by toxicity and side effects of multimodal therapy strategies in which it is associated with poor prognosis for patients. There is an urgent necessity to develop novel therapy strategies and to utilize preventive potential of natural compounds. As the majority of anticancer drugs are of natural origin, natural products represent a valuable source for the identification and development of novel treatment options and chemopreventive mechanisms for cancer. This review is focused on the summary of published knowledges on the antioxidant and potential chemopreventive effects of biologically active substances present in the extracts of four plants of the family Lamiaceae (sage, thyme, rosemary and lavander) in different animal and in vitro systems. It is assumed that the chemopreventive and chemotherapeutic potential of natural compounds is the result of a combined action of several mechanisms.

    Full Text Available The contribution of modern science to the progress of civilization is immeasurable. Even its tendency toward exclusive concentration on the objective world has had salutary effects of great value. Modern science has wiped away much that was merely superstitious or speculative. Its rejection of unfounded opinions and prejudices has helped the thinking mind question conventional beliefs, shed preferences and prejudices, and challenge established authority. But modern systems thinking inherited from natural science is the suppression of the subjective dimension of reality. Many complex systems are an attempt to define and represent all subjective experience in physical terms. The modern man has a bias towards objectivity. The powerful influence of sense impressions on his mind and thinking makes him ignore the subjective experience and consider only objective facts as a valid, legitimate and representation of reality. Observing objective factors that are physical is easier than observing subjective factors that are subtle. The mechanistic view of reality has led to the rejection of the role of the individual in social development as insignificant. The individuals determine the development of society. Their social power has its roots both in subjective factors and objective factors. Economy, politics, society, and culture are inseparable dimensions of a single integrated reality. Subject and object constitute an integrated whole. The mind sees them as separate and independent. Or it views one as completely subordinate to the other. Unbiased approach to the study of all human experiences may prove that subject and object are interdependent dimensions or elements of reality.

    Granuloma faciale is a rare skin disorder, characterized by asymptomatic cutaneous nodules on the face without any systemic manifestations. The disorder mainly affects middle-aged Caucasian males. One such case occurring in a young unmarried lady of "Pathan" descent is presented here. The presentation was unusual due to the history of frequent swelling, redness and heat in her nodules without any known stimuli and spontaneous regression of the nodules to the original size in a few hours. The patient was treated with a combination of cryotherapy and intralesional corticosteroids with excellent results.

    Background Motif mining has always been a hot research topic in bioinformatics. Most of current research on biological networks focuses on exact motif mining. However, due to the inevitable experimental error and noisy data, biological network data represented as the probability model could better reflect the authenticity and biological significance, therefore, it is more biological meaningful to discover probability motif in uncertain biological networks. One of the key steps in probability motif mining is frequent pattern discovery which is usually based on the possible world model having a relatively high computational complexity. Methods In this paper, we present a novel method for detecting frequent probability patterns based on circuit simulation in the uncertain biological networks. First, the partition based efficient search is applied to the non-tree like subgraph mining where the probability of occurrence in random networks is small. Then, an algorithm of probability isomorphic based on circuit simulation is proposed. The probability isomorphic combines the analysis of circuit topology structure with related physical properties of voltage in order to evaluate the probability isomorphism between probability subgraphs. The circuit simulation based probability isomorphic can avoid using traditional possible world model. Finally, based on the algorithm of probability subgraph isomorphism, two-step hierarchical clustering method is used to cluster subgraphs, and discover frequent probability patterns from the clusters. Results The experiment results on data sets of the Protein-Protein Interaction (PPI) networks and the transcriptional regulatory networks of E. coli and S. cerevisiae show that the proposed method can efficiently discover the frequent probability subgraphs. The discovered subgraphs in our study contain all probability motifs reported in the experiments published in other related papers. Conclusions The algorithm of probability graph isomorphism

    Recent advances in genomics, recombinant expression technologies and peptide synthesis have led to an increased development of protein and peptide therapeutics. Unfortunately this goes hand in hand with a growing market of counterfeit and illegal biopharmaceuticals, including substances that are still under pre-clinical and clinical development. These counterfeit and illegal protein and peptide substances could imply severe health threats as has been demonstrated by numerous case reports. The Belgian Federal Agency for Medicines and Health Products (FAMHP) and customs are striving, together with their global counterparts, to curtail the trafficking and distributions of these substances. At their request, suspected protein and peptide preparations are analysed in our Official Medicines Control Laboratory (OMCL). It stands to reason that a general screening method would be beneficiary in the battle against counterfeit and illegal peptide drugs. In this paper we present such general screening method employing liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the identification of counterfeit and illegal injectable peptide preparations, extended with a subsequent quantification method using ultra-high performance liquid chromatography with diode array detection (UHPLC-DAD). The screening method, taking only 30 min, is able to selectively detect 25 different peptides and incorporates the proposed minimum of five identification points (IP) as has been recommended for sports drug testing applications. The group of peptides represent substances which have already been detected in illegal and counterfeit products seized by different European countries as well as some biopharmaceutical peptides which have not been confiscated yet by the controlling agencies, but are already being used according to the many internet users forums. Additionally, we also show that when applying the same LC gradient, it is also possible to quantify these peptides without the need for

  13. Visual perception of spatial subjects

    Principally, any imaging technology consists of two consecutive, though strictly separated processes: data acquisition and subsequent processing to generate an image that can be looked at, either on a monitor screen or printed on paper. Likewise, the physiological process of viewing can be separated into vision and perception, though these processes are much more overlapping. Understanding the appearance of a subject requires the entire sequence from receiving the information carried e.g. by photons up to an appropriate processing leading to the perception of the subject shown. As a consequence, the imagination of a subject is a result of both, technological and physiological processes. Whenever an evaluation of an image is critical, also the physiological part of the processing should be considered. However, an image has two dimensions in the first place and reality is spatial, it has three dimensions. This problem has been tackled on a philosophical level at least since Platon's famous discussion on the shadow image in a dark cave. The mere practical point is which structural details can be perceived and what may remain undetected depending on the mode of presentation. This problem cannot be resolved without considering each single step of visual perception. Physiologically, there are three 'tools' available to understanding the spatial structure of a subject: binocular viewing, following the course of perspective projection and motion to collect multiple aspects. Artificially, an object may be cut in various ways to display the interior or covering parts could be made transparent within a model. Samples will be shown how certain details of a subject can be emphasised or hidden depending on the way of presentation. It needs to be discussed what might help to perceive the true spatial structure of a subject with all relevant details and what could be misleading. (authors)

  15. Frequent gain and loss of introns in fungal cytochrome b genes.

    Directory of Open Access Journals (Sweden)

    Liang-Fen Yin

    Full Text Available In this study, all available cytochrome b (Cyt b genes from the GOBASE database were compiled and the evolutionary dynamics of the Cyt b gene introns was assessed. Cyt b gene introns were frequently present in the fungal kingdom and some lower plants, but generally absent or rare in Chromista, Protozoa, and Animalia. Fungal Cyt b introns were found at 35 positions in Cyt b genes and the number of introns varied at individual positions from a single representative to 32 different introns at position 131, showing a wide and patchy distribution. Many homologous introns were present at the same position in distantly related species but absent in closely related species, suggesting that introns of the Cyt b genes were frequently lost. On the other hand, highly similar intron sequences were observed in some distantly related species rather than in closely related species, suggesting that these introns were gained independently, likely through lateral transfers. The intron loss-and-gain events could be mediated by transpositions that might have occurred between nuclear and mitochondria. Southern hybridization analysis confirmed that some introns contained repetitive sequences and might be transposable elements. An intron gain in Botryotinia fuckeliana prevented the development of QoI fungicide resistance, suggesting that intron loss-and-gain events were not necessarily beneficial to their host organisms.

    Whereas several studies have examined the association between frequent attendance in primary care and illness-specific psychological factors, little is known about the relation between frequent attendance and general psychological factors. Thus, the aim of this study was to investigate the association between being a frequent attender in primary care and general psychological factors. Data were used from a large, population-based sample of community-dwelling individuals aged 40 and above in Germany in 2014 (n = 7,446). Positive and negative affect, life satisfaction, optimism, self-esteem, self-efficacy, and self-regulation were included as general psychological factors. The number of self-reported GP visits in the past twelve months was used to quantify frequency of attendance; individuals with more than 9 visits (highest decile) were defined as frequent attenders. Multiple logistic regressions showed that being a frequent attender was positively associated with less life satisfaction [OR: 0.79 (0.70-0.89)], higher negative affect [OR: 1.38 (1.17-1.62)], less self-efficacy [OR: 0.74 (0.63-0.86)], less self-esteem [OR: 0.65 (0.54-0.79)], less self-regulation [OR: 0.74 (0.60-0.91)], and higher perceived stress [OR: 1.46 (1.28-1.66)], after adjusting for sociodemographic factors, morbidity and lifestyle factors. However, frequent attendance was not significantly associated with positive affect and self-regulation. The present study highlights the association between general psychological factors and frequent attendance. As frequent GP visits produce high health care costs and are potentially associated with increased referrals and use of secondary health care services, this knowledge might help to address these individuals with high needs.

    Magnetoencephalography (MEG) was used to determine the neuroanatomical location of working memory (WM) processes. Differences between subjects with dyslexia (SD; n=5) and normal readers (NR; n=5) were studied during two WM tasks. A spatial WM task (SMW) consisted of blocks visually presented in one of 12 positions for 2 s each. Subjects were to determine if the current position matched the position presented 2 slides earlier (N-Back Test). The verbal task (VMW) consisted of presentation of a single letter. The location of cortical activity during SWM in NR (determined with MR-FOCUSS analysis) was in the right superior temporal gyrus (STG) and right angular gyrus (AG). Similar activation was seen in SD with a slight delay of approximately 20 ms. During VWM activity was seen in LEFT STG and LEFT AG in NR. In contrast for SD, activation was in the RIGHT STG and RIGHT AG. This study demonstrates the possibility to differentiate WM processing in subjects with and without learning disorders.

    Despite extensive efforts, half of patients with rare movement disorders such as hereditary spastic paraplegias and cerebellar ataxias remain genetically unexplained, implicating novel genes and unrecognized mutations in known genes. Non-coding DNA variants are suspected to account for a substantial part of undiscovered causes of rare diseases. Here we identified mutations located deep in introns of POLR3A to be a frequent cause of hereditary spastic paraplegia and cerebellar ataxia. First, whole-exome sequencing findings in a recessive spastic ataxia family turned our attention to intronic variants in POLR3A, a gene previously associated with hypomyelinating leukodystrophy type 7. Next, we screened a cohort of hereditary spastic paraplegia and cerebellar ataxia cases (n = 618) for mutations in POLR3A and identified compound heterozygous POLR3A mutations in ∼3.1% of index cases. Interestingly, >80% of POLR3A mutation carriers presented the same deep-intronic mutation (c.1909+22G>A), which activates a cryptic splice site in a tissue and stage of development-specific manner and leads to a novel distinct and uniform phenotype. The phenotype is characterized by adolescent-onset progressive spastic ataxia with frequent occurrence of tremor, involvement of the central sensory tracts and dental problems (hypodontia, early onset of severe and aggressive periodontal disease). Instead of the typical hypomyelination magnetic resonance imaging pattern associated with classical POLR3A mutations, cases carrying c.1909+22G>A demonstrated hyperintensities along the superior cerebellar peduncles. These hyperintensities may represent the structural correlate to the cerebellar symptoms observed in these patients. The associated c.1909+22G>A variant was significantly enriched in 1139 cases with spastic ataxia-related phenotypes as compared to unrelated neurological and non-neurological phenotypes and healthy controls (P = 1.3 × 10-4). In this study we demonstrate that (i) autosomal

    Full Text Available Introduction. Morphine addiction and morphine withdrawal syndrome are the two main problems of today’s human society. The present study has investigated the effects of nicotine on the strength of physical and psychological dependency in single and repeated doses morphine administrated rats. Materials and methods. Male Wistar rats were subjected to morphine consumption with single or frequent dose protocols. In the single dose protocol, rats received only one dose of morphine and 24hrs later they also received one dose of nicotine 30 min prior to injection of naloxone. In the repeated dose protocol, rats received incremental doses of morphine for 7 days and 24hr after the last dose (the 8th day were given naloxone. However, the nicotine regimen of this group was injected 15 min before the morphine injection, for 4 days, from the 4th to the 7th day. Five minutes after naloxone injection, each rat′s behavior was captured for 30 min, and then physical and psychological signs of withdrawal syndrome were recorded. Data were analyzed by ANOVA followed by Tukey tests and p<0.05 was considered as significant difference. Findings. Results showed that the injection of frequent and single doses of morphine lead to morphine dependency. In single dose protocol, nicotine consumption attenuated the signs of withdrawal syndrome, especially weight of excrement and total withdrawal score. In frequent dose protocol, in addition to these effects, nicotine induced weight loss and place aversion. Conclusion. The inhibitory effects of nicotine on signs of withdrawal syndrome may involve a dopaminergic portion of the central nervous system and is mediated by central nicotinic receptors. There is also a cross-dependence between nicotine and morphine.

    Corticosteroid (budesonide) nebulizer therapy is commonly performed. Its side effects have been considered as being safe or ignorable. The authors present a case of esophageal candidiasis in a healthy female adolescent who was treated with budesonide nebulizer therapy a few times for a cough during the previous winter season. This child presented with dysphagia and epigastric pain for 1 month. Esophageal endoscopy showed a whitish creamy pseudomembrane and erosions on the esophageal mucosa. Pathologic findings showed numerous candidal hyphae. She did not show any evidence of immunodeficiency, clinically and historically. The esophageal lesion did not resolve naturally. The esophageal lesion completely improved with the antifungal therapy for 2 weeks; the symptoms disappeared, and the patient returned to normal health. It is important that frequent esophageal exposure to topical corticosteroids application can cause unexpected side effects.

    Europe is the largest producer of wheat, the second most widely grown cereal crop after rice. The increased occurrence and magnitude of adverse and extreme agroclimatic events are considered a major threat for wheat production. We present an analysis that accounts for a range of adverse weather...... events that might significantly affect wheat yield in Europe. For this purpose we analysed changes in the frequency of the occurrence of 11 adverse weather events. Using climate scenarios based on the most recent ensemble of climate models and greenhouse gases emission estimates, we assessed...... the probability of single and multiple adverse events occurring within one season. We showed that the occurrence of adverse conditions for 14 sites representing the main European wheat-growing areas might substantially increase by 2060 compared to the present (1981–2010). This is likely to result in more frequent...

    Context: Congenital glaucoma is a potentially blinding ocular disease of the childhood. Identification of the possible associated risk factors and may be helpful for prevention or early detection of this public health problem. Aims: To demonstrate the demographic features of congenital glaucoma subjects. Setting and Design: The charts of congenital glaucoma patients referred to Tamcelik Glaucoma Center were retrospectively reviewed through the dates of 2000 and 2013. Materials and Methods: Analyzed data included diagnosis, age at first presentation, symptoms at first presentation, laterality of the disease, sex, presence of consanguinity, family history of congenital glaucoma, maturity of the fetus at delivery, and maternal age at conception. Statistical Analysis Used: Statistical Package for Social Sciences (SPSS) version 19.0 by IBM (SPSS Inc, Chicago, Illinois, USA) was used to compare the mean of continuous variables with Student's t-test and analysis of variance (ANOVA) and χ2 test was used to test differences in proportions of categorical variables. Results: The data of 600 eyes of 311 patients were analyzed. The distribution of primary and secondary congenital glaucoma among the patients were 63.3% (n = 197) and 36.7% (n = 114), respectively. Of the 311 patients, 57.2% (n = 178) were male and 42.8% (n = 133) were female. The overall frequency of bilateral disease was 92.3% (n = 287). Overall rate of consanguinity and positive family history was 45.3% (n = 141) and 21.2% (n = 66), respectively. Conclusions: Bilateral disease in this study was more common than previously reported studies. Positive family history was more frequent in primary congenital glaucoma although not statistically significant. PMID:24881602

  4. Turtle: identifying frequent k-mers with cache-efficient algorithms.

    2014-07-15

    Counting the frequencies of k-mers in read libraries is often a first step in the analysis of high-throughput sequencing data. Infrequent k-mers are assumed to be a result of sequencing errors. The frequent k-mers constitute a reduced but error-free representation of the experiment, which can inform read error correction or serve as the input to de novo assembly methods. Ideally, the memory requirement for counting should be linear in the number of frequent k-mers and not in the, typically much larger, total number of k-mers in the read library. We present a novel method that balances time, space and accuracy requirements to efficiently extract frequent k-mers even for high-coverage libraries and large genomes such as human. Our method is designed to minimize cache misses in a cache-efficient manner by using a pattern-blocked Bloom filter to remove infrequent k-mers from consideration in combination with a novel sort-and-compact scheme, instead of a hash, for the actual counting. Although this increases theoretical complexity, the savings in cache misses reduce the empirical running times. A variant of method can resort to a counting Bloom filter for even larger savings in memory at the expense of false-negative rates in addition to the false-positive rates common to all Bloom filter-based approaches. A comparison with the state-of-the-art shows reduced memory requirements and running times.

  5. Science of the subjective.

    Jahn, R G; Dunne, B J

    2007-01-01

    Over the greater portion of its long scholarly history, the particular form of human observation, reasoning, and technical deployment we properly term "science" has relied at least as much on subjective experience and inspiration as it has on objective experiments and theories. Only over the past few centuries has subjectivity been progressively excluded from the practice of science, leaving an essentially secular analytical paradigm. Quite recently, however, a compounding constellation of newly inexplicable physical evidence, coupled with a growing scholarly interest in the nature and capability of human consciousness, are beginning to suggest that this sterilization of science may have been excessive and could ultimately limit its epistemological reach and cultural relevance. In particular, an array of demonstrable consciousness-related anomalous physical phenomena, a persistent pattern of biological and medical anomalies, systematic studies of mind/brain relationships and the mechanics of human creativity, and a burgeoning catalogue of human factors effects within contemporary information processing technologies, all display empirical correlations with subjective aspects that greatly complicate, and in many cases preclude, their comprehension on strictly objective grounds. However, any disciplined re-admission of subjective elements into rigorous scientific methodology will hinge on the precision with which they can be defined, measured, and represented, and on the resilience of established scientific techniques to their inclusion. For example, any neo-subjective science, while retaining the logical rigor, empirical/theoretical dialogue, and cultural purpose of its rigidly objective predecessor, would have the following requirements: acknowledgment of a proactive role for human consciousness; more explicit and profound use of interdisciplinary metaphors; more generous interpretations of measurability, replicability, and resonance; a reduction of ontological

    Medically unexplained somatic symptoms present a real challenge to modem medicine. They occur frequently and are often chronic. To discuss the physician's approach to these symptoms. We focus on the views of the human body put forward by the French philosopher Merleau-Ponty. His view is illustrated with the help of a case study concerning a patient suffering from borderline personality disorder and complex regional pain syndrome. Merleau-Ponty draws a distinction between body-subject and body-object. By body-object he means the body as determined and predicted by medical science. By body-subject he means the body as we experience it, even before we are aware of it. It is our pre-reflexive body that gives meaning to the world around us. We argue that the physician should regard the body not only as an object, but also as a subject, thereby giving renewed attention to the significance of symptoms as an expression of inner experience. In this way symptoms that cannot be explained on a purely physico-chemical level will become more meaningful.

  7. The Subjectivity of Participation

    Nissen, Morten

    What is a 'we' – a collective – and how can we use such communal self-knowledge to help people? This book is about collectivity, participation, and subjectivity – and about the social theories that may help us understand these matters. It also seeks to learn from the innovative practices and ideas...... practices. Through this dialogue, it develops an original trans-disciplinary critical theory and practice of collective subjectivity for which the ongoing construction and overcoming of common sense, or ideology, is central. It also points to ways of relating discourse with agency, and fertilizing insights...... from interactionism and ideology theories in a cultural-historical framework....

  9. Detecting individual sites subject to episodic diversifying selection.

    Directory of Open Access Journals (Sweden)

    Ben Murrell

    Full Text Available The imprint of natural selection on protein coding genes is often difficult to identify because selection is frequently transient or episodic, i.e. it affects only a subset of lineages. Existing computational techniques, which are designed to identify sites subject to pervasive selection, may fail to recognize sites where selection is episodic: a large proportion of positively selected sites. We present a mixed effects model of evolution (MEME that is capable of identifying instances of both episodic and pervasive positive selection at the level of an individual site. Using empirical and simulated data, we demonstrate the superior performance of MEME over older models under a broad range of scenarios. We find that episodic selection is widespread and conclude that the number of sites experiencing positive selection may have been vastly underestimated.

    This paper introduces new approaches for the analysis of frequent statement and dereference elimination for imperative and object-oriented distributed programs running on parallel machines equipped with hierarchical memories. The paper uses languages whose address spaces are globally partitioned. Distributed programs allow defining data layout and threads writing to and reading from other thread memories. Three type systems (for imperative distributed programs) are the tools of the proposed techniques. The first type system defines for every program point a set of calculated (ready) statements and memory accesses. The second type system uses an enriched version of types of the first type system and determines which of the ready statements and memory accesses are used later in the program. The third type system uses the information gather so far to eliminate unnecessary statement computations and memory accesses (the analysis of frequent statement and dereference elimination). Extensions to these type systems are also presented to cover object-oriented distributed programs. Two advantages of our work over related work are the following. The hierarchical style of concurrent parallel computers is similar to the memory model used in this paper. In our approach, each analysis result is assigned a type derivation (serves as a correctness proof).

    1989-04-01

    A family is reported in which three generations were affected with eye-winking tics and/or blepharospasm. The proband developed eye-winking tics in childhood and then developed excessive blinking progressing to blepharospasm by the age of 21 years. His mother presented with Meige's syndrome and spasmodic torticollis at the age of 59 years; his uncle had blinked excessively from his early forties. His eldest son developed an eye-winking tic with facial grimacing at the age of 8 years, and in another son, a self-limiting period of eye-blinking occurred at the age of 4 years. The recovery cycle of the blink reflex was abnormal in all three generations. Three other children with eye-winking tics have a parent or close relative with frequent eye-blinking or blepharospasm. Five patients with adult-onset blepharospasm or Meige's syndrome are also described who had excessive eye-blinking dating back to childhood. It is suggested that eye-winking tics, frequent blinking and blepharospasm may share common pathophysiological mechanisms; the clinical expression may be age-related.

  14. Frequent beneficial mutations during single-colony serial transfer of Streptococcus pneumoniae.

    2011-08-01

    Full Text Available The appearance of new mutations within a population provides the raw material for evolution. The consistent decline in fitness observed in classical mutation accumulation studies has provided support for the long-held view that deleterious mutations are more common than beneficial mutations. Here we present results of a study using a mutation accumulation design with the bacterium Streptococcus pneumoniae in which the fitness of the derived populations increased. This rise in fitness was associated specifically with adaptation to survival during brief stationary phase periods between single-colony population bottlenecks. To understand better the population dynamics behind this unanticipated adaptation, we developed a maximum likelihood model describing the processes of mutation and stationary-phase selection in the context of frequent population bottlenecks. Using this model, we estimate that the rate of beneficial mutations may be as high as 4.8×10(-4 events per genome for each time interval corresponding to the pneumococcal generation time. This rate is several orders of magnitude higher than earlier estimates of beneficial mutation rates in bacteria but supports recent results obtained through the propagation of small populations of Escherichia coli. Our findings indicate that beneficial mutations may be relatively frequent in bacteria and suggest that in S. pneumoniae, which develops natural competence for transformation, a steady supply of such mutations may be available for sampling by recombination.

  15. Unique program aims to connect frequent ED utilizers with medical homes, resources to meet complex needs.

    2014-10-01

    Sinai Hospital of Baltimore in Baltimore, MD, is partnering with HealthCare Access Maryland, a non-profit organization in the state, to link patients who frequent the ED for care with medical homes and other resources that can better meet their medical and social needs. Under the Access Health Program, ED-based care coordinators intervene with patients who meet program criteria, linking them with medical homes and other resources that address their complex needs. The hospital has devised a flag to notify the ED when a frequent-utilizing patient presents in the department for care. Care coordinators then meet with these patients and get their consent to participate in the program. Within a week of the ED visit, care coordinators schedule a home visit with the patient to establish a care plan containing specific goals and a time frame to carry out these goals. Patients remain in the program for 90 days as care coordinators work to hand them off to longer-term resources. Many of the patients enrolled in the program have substance abuse and mental health problems. Patients are also often uninsured and/or homeless. Within two months of launching the program, care coordinators enrolled 74 patients, with the goal of eventually bringing that number to 200.

    2013-01-01

    Full Text Available Diabetic myonecrosis is a frequently unrecognized complication of longstanding and poorly controlled diabetes mellitus. The clinical presentation is swelling, pain, and tenderness of the involved muscle, most commonly the thigh muscles. Management consists of conservative measures including analgesia and rest. Short-term prognosis is good, but long-term prognosis is poor with most patients dying within 5 years. Failure to properly identify this condition will expose the patient to aggressive measures that could result in increased morbidity. To our knowledge this is the first case reported in which there was involvement of multiple muscle groups including upper and lower limbs.

    CONTEXT Cash payments are often used to compensate subjects who participate in research. However, ethicists have argued that these payments might constitute an undue inducement. OBJECTIVES To determine whether potential subjects agree with theoretical arguments that a payment could be an undue inducement. DESIGN/SETTING/PARTICIPANTS Survey of 350 prospective jurors. MAIN OUTCOME MEASURES Belief that a $500 payment for research participation would impair their own, and others' ability to think carefully about the risks and benefits of a clinical trial. RESULTS Two hundred sixty-one jurors (74.6%) believed that a $500 payment would impair subjects' ability to think carefully about the risks and benefits of research. Ninety-six of 120 (80%) expressed this concern about subjects with a low income ($50,000). In contrast, only 69 (19.7%) of jurors believed that a $500 payment would influence them. Jurors who believed that this payment would influence them reported lower incomes and less education. CONCLUSION Members of the general public share ethical concerns about the influence of payments for research, although they believe that these concerns are more applicable to others than to themselves.

    Accurately predicting future frequent emergency department (ED) utilization can support a case management approach and ultimately reduce health care costs. This study assesses the feasibility of using routinely collected registration data to predict future frequent ED visits. Using routinely collected registration data in the state of Indiana, U.S.A., from 2008, we developed multivariable logistic regression models to predict frequent ED visits in the subsequent two years. We assessed the model's accuracy using Receiver Operating Characteristic (ROC) curves, sensitivity, and positive predictive value (PPV). Strong predictors of frequent ED visits included age between 25 and 44 years, female gender, close proximity to the ED (less than 5 miles traveling distance), total visits in the baseline year, and respiratory and dental chief complaint syndromes. The area under ROC curve (AUC) ranged from 0.83 to 0.92 for models predicting patients with 8 or more visits to 16 or more visits in the subsequent two years, suggesting acceptable discrimination. With 25 % sensitivity, the model predicting frequent ED use as defined as 16 or more visits in 2009 and 2010 had a PPV of 59.5 % and specificity of 99.9 %. The "adjusted" PPV of this model, which includes patients having 8 or more visits, is 81.9 %. We demonstrate a strong association between predictor variables present in registration data and frequent ED use. The algorithm's performance characteristics suggest that it is technically feasible to use routinely collected registration data to predict future frequent ED use.

    Full Text Available Discute-se largamente, na literatura psicanalítica e no meio acadêmico, de modo geral, sobre o declínio das tradições, do respeito às e respaldo social das instituições, e sobre a desqualificação da autoridade paterna na contemporaneidade. Tributário do romantismo e do individualismo forjados na modernidade, o amor romântico enquanto valor cultural e último refúgio subjetivo também se encontra em ruínas. A sexualidade enquanto absoluto prazer, multiplicidade e busca de sensações, é projetada cada vez mais como condição para as relações ditas amorosas. Diante desse cenário, partimos de uma discussão teórica e de vinhetas clínicas, a fim de argumentar que o ciúme é um afeto "fora de moda", cujas manifestações sintomáticas podem ser associadas ao modo como o erotismo é regido na atualidade. A ausência de ciúme desponta como um novo ideal para o amor, não mais apenas romântico, porém, antes de mais nada, narcísico, erótico, múltiplo e excessivo. A partir de estudos psicanalíticos sobre o amor e o ciúme, pretendemos então refletir como o modelo cultural narcísico atual permeado pelos restos de um romantismo recrudescente afeta a subjetividade. De modo ambíguo, a "ausência de ciúme" e seu oposto correlato "ciúme primitivo" oscilam entre si como expressões marcantes da fragilidade nas relações amorosas atuais.The decline of traditions, institutions and paternal authority in present times has been largely discussed in psychoanalytical literature.

    Full Text Available Abstract Background Quality of life may be affected by daily injections of supportive hematopoietic growth factor medication, which is frequently required by patients with cancer undergoing chemotherapy. The objective of the study was to identify areas where long-acting derivatives of current proteins, which require less frequent administration, may provide advantages over existing therapies that require more frequent administration. Methods An observational study was conducted to assess the impact of daily injections of Filgrastim (Neupogen®; Amgen Inc. on patients' quality of life. A Subject Outcome Questionnaire was administered to patients after chemotherapy on 2 consecutive cycles. Time spent for treatment and patient attitude towards injection frequency were measured. The effect on patients' daily activities, including their ability to work, was analyzed. Results Thirty patients completed the first, and 24 the second, administration of the Questionnaire across 3 participating sites in the United States. The average patient time commitment for each daily injection was 78 minutes. Forty-five percent of patients were moderately to extremely bothered by travel during the first chemotherapy cycle, which increased to 59% during the second cycle. Forty-four percent and 18% of patients reported having to rearrange their daily schedules and take time off from work to accommodate each injection at least some of the time, respectively. Eighty-nine percent of the patients reported a preference for a longer-acting drug that required fewer injections. Conclusion Results indicate that frequent injections represent a significant burden on patients' lives and that the majority would prefer longer-acting medications that require less frequent administration and potentially fewer clinic visits.

    Artificial insemination (AI) can help to avoid inbreeding and genetic degeneration for sustaining genetically healthy populations of endangered species in captivity. Collection of a sufficient quantity of viable sperm is an essential first step in the AI process. In the present study, we examined the effects of frequent electroejaculation on semen characteristics in a Siberian tiger. We collected semen in all 17 trials during 6 breeding seasons (6 years). The mean number of sperm and the percentage of motile sperm were 294.3 ± 250.2 × 10⁶/ejaculate and 82.4 ± 11.4%, respectively. The number of motile sperm tended to increase during frequent electroejaculation in the same breeding season. Semen collection by electroejaculation can be performed effectively up to the fourth sequential ejaculate, which contained the most sperm in the study. In conclusion, frequent collection of sperm by electroejaculation from tigers may be effective for collection of a large number of motile sperm.

    Full Text Available The study estimated the prevalence of HIV-1 intra-subtype recombinant variants among female bar and hotel workers in Tanzania. While intra-subtype recombination occurs in HIV-1, it is generally underestimated. HIV-1 env gp120 V1-C5 quasispecies from 45 subjects were generated by single-genome amplification and sequencing (median (IQR of 38 (28-50 sequences per subject. Recombination analysis was performed using seven methods implemented within the recombination detection program version 3, RDP3. HIV-1 sequences were considered recombinant if recombination signals were detected by at least three methods with p-values of ≤0.05 after Bonferroni correction for multiple comparisons. HIV-1 in 38 (84% subjects showed evidence for intra-subtype recombination including 22 with HIV-1 subtype A1, 13 with HIV-1 subtype C, and 3 with HIV-1 subtype D. The distribution of intra-patient recombination breakpoints suggested ongoing recombination and showed selective enrichment of recombinant variants in 23 (60% subjects. The number of subjects with evidence of intra-subtype recombination increased from 29 (69% to 36 (82% over one year of follow-up, although the increase did not reach statistical significance. Adjustment for intra-subtype recombination is important for the analysis of multiplicity of HIV infection. This is the first report of high prevalence of intra-subtype recombination in the HIV/AIDS epidemic in Tanzania, a region where multiple HIV-1 subtypes co-circulate. HIV-1 intra-subtype recombination increases viral diversity and presents additional challenges for HIV-1 vaccine design.

    It is still debated whether the deterioration of the sleep pattern, frequently reported by elderly subjects, is due only to aging per se. Other factors associated with aging or modifications of biological rhythms could also be involved. Elderly subjects frequently complain of daytime sleepiness, but it is not clear whether this actually represents a return to a polyphasic structure of sleep, or only a consequence of a disturbed night sleep. Ten healthy, independent and active elderly subjects (age > 72 years) were elevated by means of 24-hour ambulatory polysomnography. Findings of nocturnal sleep were compared with sleep of the same group in the 24-hour period and with sleep of young healthy controls. We observed a fragmentation of nocturnal sleep, but a fairly good representation of stages and a preservation of cyclicity. Except for three cases, with early or late times of sleep onset and wake-up, sleep disruption did not seem to be related to modification of circadian rhythms. Only three subjects presented undesired daytime naps, whereas the others either did not show daytime sleep at all, or were used to having their siesta after lunch since their young adulthood. In normal aging, daytime sleep does not constitute a social problem. Ambulatory polysomnography is a valid alternative to laboratory recordings in the identification of daytime sleep.

    Severe floods triggered by intense precipitation are among the most destructive natural hazards in Alpine environments, frequently causing large financial and societal damage. Potential enhanced flood occurrence due to global climate change would thus increase threat to settlements, infrastructure, and human lives in the affected regions. Yet, projections of intense precipitation exhibit major uncertainties and robust reconstructions of Alpine floods are limited to the instrumental and historical period. Here we present a 2500-year long flood reconstruction for the European Alps, based on dated sedimentary flood deposits from ten lakes in Switzerland. We show that periods with high flood frequency coincide with cool summer temperatures. This wet-cold synchronism suggests enhanced flood occurrence to be triggered by latitudinal shifts of Atlantic and Mediterranean storm tracks. This paleoclimatic perspective reveals natural analogues for varying climate conditions, and thus can contribute to a better understanding and improved projections of weather extremes under climate change.

    Full Text Available Putrescine, spermidine and spermine are the most abundant polycationic natural amines found in nearly all organisms. They are involved in regulation of gene expression, translation, cell proliferation and differentiation. They can be supplied by the endogenous synthesis inside the cell or by the intake from exogenous sources. There is a growing body of literature associated with the effects of bioactive amines on health and diseases, but limited information about polyamine content in foods is available. In the present study, the polyamine content of frequently consumed foods in a typical Turkish diet was estimated for adults, including tea, bread and yoghurt. The estimation of daily intake was defined as 93,057 nmol/day putrescine, 33,122 nmol/day spermidine, 13,685 nmol/day spermine. The contribution of foods to daily intake was: dairy products (47.32%, vegetables and grains (21.09% and wheat products (12.75%.

    Sickle cell disease (HbS) is a haemolytic anaemia characterized by the formation of abnormal haemoglobin. In patients with sickle cell disease, high rates of erythrocyte generation, degradation, and hyperbilirubinemia increase the risk for cholelithiasis. Previous studies have found that the incidence of cholelithiasis is 70% in adult patients. In sickle cell disease, decreased oxygen concentration leads to the sickling of erythrocytes by causing aggregation and polymerization. Sickle erythrocytes can have devastating effects on many vital organs by causing microvascular occlusion. In patients with sickle cell anaemia, anaesthetic technique, anaesthetic agents, and surgical trauma may cause additional risk. In this case report, we present a perioperative anaesthetic approach in the laparoscopic cholecystectomy of a patient with HbS, elevated liver function tests, and frequent pain crises.

  19. Making your presentation fun: creative presentation techniques

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

  20. Frequently updated noise threat maps created with use of supercomputing grid

    Full Text Available An innovative supercomputing grid services devoted to noise threat evaluation were presented. The services described in this paper concern two issues, first is related to the noise mapping, while the second one focuses on assessment of the noise dose and its influence on the human hearing system. The discussed serviceswere developed within the PL-Grid Plus Infrastructure which accumulates Polish academic supercomputer centers. Selected experimental results achieved by the usage of the services proposed were presented. The assessment of the environmental noise threats includes creation of the noise maps using either ofline or online data, acquired through a grid of the monitoring stations. A concept of estimation of the source model parameters based on the measured sound level for the purpose of creating frequently updated noise maps was presented. Connecting the noise mapping grid service with a distributed sensor network enables to automatically update noise maps for a specified time period. Moreover, a unique attribute of the developed software is the estimation of the auditory effects evoked by the exposure to noise. The estimation method uses a modified psychoacoustic model of hearing and is based on the calculated noise level values and on the given exposure period. Potential use scenarios of the grid services for research or educational purpose were introduced. Presentation of the results of predicted hearing threshold shift caused by exposure to excessive noise can raise the public awareness of the noise threats.

    Research on the effects of media violence exposure has shown robust associations among violent media exposure, increased aggressive behavior, and decreased empathy. Preliminary research indicates that frequent players of violent video games may have differences in emotional and cognitive processes compared to infrequent or nonplayers, yet research examining the amount and content of game play and the relation of these factors with affective and cognitive outcomes is limited. The present study measured neural correlates of response inhibition in the context of implicit attention to emotion, and how these factors are related to empathic responding in frequent and infrequent players of video games with graphically violent content. Participants completed a self-report measure of empathy as well as an affective stop-signal task that measured implicit attention to emotion and response inhibition during electroencephalography. Frequent players had lower levels of empathy as well as a reduction in brain activity as indicated by P100 and N200/P300 event related potentials. Reduced P100 amplitude evoked by happy facial expressions was observed in frequent players compared to infrequent players, and this effect was moderated by empathy, such that low levels of empathy further reduced P100 amplitudes for happy facial expressions for frequent players compared to infrequent players. Compared to infrequent players, frequent players had reduced N200/P300 amplitude during response inhibition, indicating less neural resources were recruited to inhibit behavior. Results from the present study illustrate that chronic exposure to violent video games modulates empathy and related neural correlates associated with affect and cognition. © The Author (2017).

    Fieldwork is one of the important methods in educational, social, and organisational research. In fieldwork, the researcher takes residence for a shorter or longer period amongst the subjects and settings to be studied. The aim of this is to study the culture of people: how people seem to make...... sense of their lives and which moral, professional, and ethical values seem to guide their behaviour and attitudes. In fieldwork, the researcher has to balance participation and observation in her attempts at representation. Consequently, the researcher’s academic and life-historical subjectivity...... are important filters for fieldwork. In general, fieldwork can be understood as processes where field reports and field analysis are determined by how the researcher interacts with and experiences the field, the events and informants in it, and how she subsequently develops an ethnography.

    Full Text Available Abstract Background There is a need for assistance from primary care mental health workers in general practice in the Netherlands. General practitioners (GPs experience an overload of frequent attenders suffering from psychological problems. Problem Solving Treatment (PST is a brief psychological treatment tailored for use in a primary care setting. PST is provided by nurses, and earlier research has shown that it is a treatment at least as effective as usual care. However, research outcomes are not totally satisfying. This protocol describes a randomized clinical trial on the effectiveness of PST provided by nurses for patients in general practice. The results of this study, which currently being carried out, will be presented as soon as they are available. Methods/design This study protocol describes the design of a randomized controlled trial to investigate the effectiveness and cost-effectiveness of PST and usual care compared to usual care only. Patients, 18 years and older, who present psychological problems and are frequent attenders in general practice are recruited by the research assistant. The participants receive questionnaires at baseline, after the intervention, and again after 3 months and 9 months. Primary outcome is the reduction of symptoms, and other outcomes measured are improvement in problem solving skills, psychological and physical well being, daily functioning, social support, coping styles, problem evaluation and health care utilization. Discussion Our results may either confirm that PST in primary care is an effective way of dealing with emotional disorders and a promising addition to the primary care in the UK and USA, or may question this assumption. This trial will allow an evaluation of the effects of PST in practical circumstances and in a rather heterogeneous group of primary care patients. This study delivers scientific support for this use and therefore indications for optimal treatment and referral.

    Maarten J Vosselman

    Full Text Available INTRODUCTION: Mild cold acclimation is known to increase brown adipose tissue (BAT activity and cold-induced thermogenesis (CIT in humans. We here tested the effect of a lifestyle with frequent exposure to extreme cold on BAT and CIT in a Dutch man known as 'the Iceman', who has multiple world records in withstanding extreme cold challenges. Furthermore, his monozygotic twin brother who has a 'normal' sedentary lifestyle without extreme cold exposures was measured. METHODS: The Iceman (subject A and his brother (subject B were studied during mild cold (13°C and thermoneutral conditions (31°C. Measurements included BAT activity and respiratory muscle activity by [18F]FDG-PET/CT imaging and energy expenditure through indirect calorimetry. In addition, body temperatures, cardiovascular parameters, skin perfusion, and thermal sensation and comfort were measured. Finally, we determined polymorphisms for uncoupling protein-1 and β3-adrenergic receptor. RESULTS: Subjects had comparable BAT activity (A: 1144 SUVtotal and B: 1325 SUVtotal, within the range previously observed in young adult men. They were genotyped with the polymorphism for uncoupling protein-1 (G/G. CIT was relatively high (A: 40.1% and B: 41.9%, but unlike during our previous cold exposure tests in young adult men, here both subjects practiced a g-Tummo like breathing technique, which involves vigorous respiratory muscle activity. This was confirmed by high [18F]FDG-uptake in respiratory muscle. CONCLUSION: No significant differences were found between the two subjects, indicating that a lifestyle with frequent exposures to extreme cold does not seem to affect BAT activity and CIT. In both subjects, BAT was not higher compared to earlier observations, whereas CIT was very high, suggesting that g-Tummo like breathing during cold exposure may cause additional heat production by vigorous isometric respiratory muscle contraction. The results must be interpreted with caution given the

    Full Text Available Mining association rules in large database is one of most popular data mining techniques for business decision makers. Discovering frequent item set is the core process in association rule mining. Numerous algorithms are available in the literature to find frequent patterns. Apriori and FP-tree are the most common methods for finding frequent items. Apriori finds significant frequent items using candidate generation with more number of data base scans. FP-tree uses two database scans to find significant frequent items without using candidate generation. This proposed TR-FCTM (Transaction Reduction- Frequency Count Table Method discovers significant frequent items by generating full candidates once to form frequency count table with one database scan. Experimental results of TR-FCTM shows that this algorithm outperforms than Apriori and FP-tree.

  15. High quality maize centromere 10 sequence reveals evidence of frequent recombination events

    Directory of Open Access Journals (Sweden)

    Thomas Kai Wolfgruber

    2016-03-01

    Full Text Available The ancestral centromeres of maize contain long stretches of the tandemly arranged CentC repeat. The abundance of tandem DNA repeats and centromeric retrotransposons (CR have presented a significant challenge to completely assembling centromeres using traditional sequencing methods. Here we report a nearly complete assembly of the 1.85 Mb maize centromere 10 from inbred B73 using PacBio technology and BACs from the reference genome project. The error rates estimated from overlapping BAC sequences are 7 x 10-6 and 5 x 10-5 for mismatches and indels, respectively. The number of gaps in the region covered by the reassembly was reduced from 140 in the reference genome to three. Three expressed genes are located between 92 and 477 kb of the inferred ancestral CentC cluster, which lies within the region of highest centromeric repeat density. The improved assembly increased the count of full-length centromeric retrotransposons from 5 to 55 and revealed a 22.7 kb segmental duplication that occurred approximately 121,000 years ago. Our analysis provides evidence of frequent recombination events in the form of partial retrotransposons, deletions within retrotransposons, chimeric retrotransposons, segmental duplications including higher order CentC repeats, a deleted CentC monomer, centromere-proximal inversions, and insertion of mitochondrial sequences. Double-strand DNA break (DSB repair is the most plausible mechanism for these events and may be the major driver of centromere repeat evolution and diversity. This repair appears to be mediated by microhomology, suggesting that tandem repeats may have evolved to facilitate the repair of frequent DSBs in centromeres.

    In the present study, the effect of frequent, immediate, augmented feedback on the increase of throwing velocity was investigated. An increase of throwing velocity of a handball set shot when knowledge of results was provided or not provided during training was compared. Fifty female and seventy-three male physical education students were assigned randomly to the experimental or control group. All participants performed two series of ten set shots with maximal effort twice a week for six weeks. The experimental group received information regarding throwing velocity measured by a radar gun immediately after every shot, whereas the control group did not receive any feedback. Measurements of maximal throwing velocity of an ordinary handball and a heavy ball were performed, before and after the training period and compared. Participants who received feedback on results attained almost a four times greater relative increase of the velocity of the normal ball (size 2) as compared to the same intervention when feedback was not provided (8.1 ± 3.6 vs. 2.7 ± 2.9%). The velocity increases were smaller, but still significant between the groups for throws using the heavy ball (5.1 ± 4.2 and 2.5 ± 5.8 for the experimental and control group, respectively). Apart from the experimental group throwing the normal ball, no differences in velocity change for gender were obtained. The results confirmed that training oriented towards an increase in throwing velocity became significantly more effective when frequent knowledge of results was provided.

    Anglophone psychology shares its vocabulary with several other subjects. Some of the more obvious subjects that have parts of their vocabulary in common with Anglophone psychology include biology (e.g., dominance), chemistry (e.g., isomorphism), philosophy (e.g., phenomenology), and theology (e.g., mediator). Using data from the Oxford English Dictionary as well as other sources, the present study explored the history of these common vocabularies, with a view to broadening our understanding of the relation between the history of psychology and the histories of other subjects. It turns out that there are at least 156 different subjects that share words with psychology. Those that have the most words in common with psychology are mathematics, biology, physics, medicine, chemistry, philosophy, law, music, linguistics, electricity, pathology, and computing. Words that have senses in other subjects and have their origins in ordinary language are used more frequently as PsycINFO keywords than words that were invented specifically for use in psychology. These and other results are interpreted in terms of the ordinary language roots of the vocabulary of Anglophone psychology and other subjects, the degree to which operational definitions have determined the meaning of the psychological senses of words, the role of the psychologist in interdisciplinary research, and the validity of psychological essentialism.

An academic outpatient clinical nutrition service in Italy. A total of 207 subjects (thirty-nine men and 168 women; mean age: 38·7 (sd 14·1) years) consecutively attending the study centre for the first time between January 2003 and December 2006. In the entire study group, eighty-three (40 %) subjects had a psychiatric disorder according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision. Eating disorders were the most prevalent psychiatric condition (thirty-six subjects, 17·4 %), followed by mood and anxiety disorders (9·7 % and 8·7 %, respectively). The frequency of psychiatric disorders among different BMI categories was as follows: 75·0 % in underweight, 50·0 % in normal weight, 33·3 % in overweight and 33·3 % in obese subjects. Psychiatric disorders may be frequently found in subjects wishing to lose weight. Our results highlight the importance of psychiatric assessment especially in underweight and normal-weight subjects.

    Full Text Available A primordial aspect of the Sartrian critique of alienation concerns understanding the analytic ideology as the domination of materiality over the symbolic, in other words as the reification of the human, and therefore as anticulture. In the context of contemporary nihilism, the decoding of the mechanisms which consign praxis to the practico-inert requires a critique of the relations between the social sciences and philosophy, which in its turn implies a new theory of the relation between what Sartre calls the "notion" (the area of subjectivity and the "concept" (objectivity, From this perspective, the deconstruction of the established frontiers between the social sciences and philosophy, and between the conceptual and the narrative, is corelative to a redefinition of the relation between theory and practice.

    A retrospective review of the demographics, co-morbidities and substance misuse of the 20 most frequent presenters to the Mater Misericordiae University Hospital emergency department during 2014 was carried out in an attempt to better understand the epidemiology of their presentations. Eighty-five percent were male and 15% female (p<0.001). The average age was 40.6 years with a median 38.5 years. All were unemployed and 7 (35%) had no fixed abode. Thirteen patients (65%) lived an average of 4.5 kilometres from the ED. In this study the presence of a mental illness, homelessness, alcohol or drug misuse were associated with significantly higher attendance rates (p=0.001, p<0.001, p<0.05, p<0.001 respectively). Early identification of these patients and targeting them for effective case-based community-led treatment strategies could improve their quality of life, decrease their cost of care and ultimately lead to more effective utilisation of our already overburdened emergency departments.

    2016-12-01

    Objectives-This report identifies the specific drugs most frequently involved in drug overdose deaths in the United States from 2010 through 2014. Methods-The 2010-2014 National Vital Statistics System mortality files were linked to electronic files containing literal text information from death certificates. Drug overdose was defined using the International Classification of Diseases, Tenth Revision underlying cause-of-death codes X40-X44 (unintentional), X60-X64 (suicide), X85 (homicide), and Y10-Y14 (undetermined intent). Among deaths with an underlying cause of death of drug overdose, the literal text in three fields of the death certificate (i.e., the cause of death from Part I, significant conditions contributing to death from Part II, and a description of how the injury occurred from Box 43) were searched to identify drug mentions. Search term lists were developed using existing drug classification systems as well as from manual review of the literal text. The search term list was then used to identify the specific drugs involved in overdose deaths. Descriptive statistics were reported for drug overdose deaths involving the 10 most frequently mentioned drugs on death certificates. Tables and figures presenting information on the specific drugs involved in deaths are based on deaths with mention of at least one specific drug on the death certificate. Results-From 2010 through 2014, the number of drug overdose deaths per year increased 23%, from 38,329 in 2010 to 47,055 in 2014. During this time period, the percentage of drug overdose deaths involving at least one specific drug increased, from 67% in 2010 to 78% in 2014. Among drug overdose deaths with at least one drug specified on the death certificate, the 10 drugs most frequently involved in overdose deaths included the following opioids: heroin, oxycodone, methadone, morphine, hydrocodone, and fentanyl; the following benzodiazepines: alprazolam and diazepam; and the following stimulants: cocaine and

    It is not well known whether systemic iron overload per se in hereditary hemochromatosis (HH) is associated with cardiac arrhythmias before other signs and symptoms of cardiovascular disease occur. In the present study, we examined the incidence of cardiac arrhythmia in cardiac asymptomatic subjects with HH (New York Heart Association functional class I) and compared it to that in age- and gender-matched normal volunteers. The 42 subjects with HH and the 19 normal control subjects were recruited through the National Heart, Lung, and Blood Institute-sponsored "Heart Study of Hemochromatosis." They completed 48-hour Holter electrocardiography ambulatory monitoring at the baseline evaluation. The subjects with HH were classified as newly diagnosed (group A) and chronically treated (group B) subjects. All subjects with HH had C282Y homozygosity, and the normal volunteers lacked any HFE gene mutations known to cause HH. Although statistically insignificant, the incidence of ventricular and supraventricular ectopy tended to be greater in the combined HH groups than in the controls. Supraventricular ectopy was more frequently noted in group B compared to in the controls (ectopy rate per hour 11.1 ± 29.9 vs 1.5 ± 3.5, p cardiac arrhythmias was not significantly reduced after 6 months of intensive iron removal therapy in the group A subjects. No life-threatening arrhythmias were observed in our subjects with HH. In conclusion, our data suggest that the incidence of cardiac arrhythmias is, at most, marginally increased in asymptomatic subjects with HH. A larger clinical study is warranted to further clarify our observation. Published by Elsevier Inc.

    Full Text Available INTRODUCTION: Brushing teeth is probably the practice of oral hygiene most common in the world; however, inadequate use can become a risk to the population health, once they may be contaminated with various microorganisms. OBJECTIVE: The aim of this study was to evaluate the bacterial contamination on toothbrush bristles using different methodologies. METHOD: We used 40 toothbrushes from healthy individuals aged 3 to 58 years. The samples were grown in test tubes containing trypticase soy broth sterile, and with the help of a tracking 0.1 μl samples were placed on plates containing sheep blood agar 5% and MacConkey agar then the samples were stored in a bacteriological incubator at 37°C for 24 hours for later analysis. It was counted the colony forming units and bacteria identification present in the brush. RESULTS: On the microbiological analysis, there was a growth of Escherichia coli, Klebsiella pneumoniae, Streptococcus pyogenes and Staphylococcus coagulase negative. CONCLUSION: According to the results presented in this study, we observed a high incidence of bacterial contamination in the brushes analyzed. The most frequent microorganisms were members of the Enterobacteriaceae. The usage time of toothbrushes may be related to contamination found and, therefore, not only good hygiene ensures the reduction of microbial load, but replacing the toothbrush can also ensure individuals better oral health.INTRODUÇÃO: a escovação de dentes é, provavelmente, a prática de higiene bucal mais comumente realizada no mundo; entretanto, o acondicionamento inadequado pode se transformar em um risco para a saúde da população, uma vez que podem estar contaminadas com vários tipos de microrganismos.

    of two or more ICDs. Patients from the nicotine-positive group drunk higher quantities of alcohol each day, consumed alcohol more frequently each week and were more often intoxicated each week with alcohol. Their mean MAST scores of alcohol abuse disorders were higher. Conclusion. A total of 45.6% of the nicotine-dependent women presented compulsive buying and 23.6% bulimia. Compulsive buying was significantly more frequent among nicotine-dependent subjects than controls. Other impulse control disorders were as frequent among nicotine-dependent women as in controls. A total of 8.6% presented explosive intermittent disorder, 4.7% pathological gambling and 5% trichotillomania. Nicotine dependence in women was also associated with a higher level of alcohol consumption. These results indicate the possible need to systematically screen nicotine-dependent women, regardless of their motivation for consultation, for alcohol dependence, bulimia and compulsive buying.

    At present, there is little information available on how practicing dentists manage bruxism patients with respect to conservative, reversible techniques as compared to irreversible techniques. The purpose of this study was to determine the most commonly applied therapies used for the management of bruxism by German general dentists (GDs) and dental specialists. In addition, efforts were made to gather information on the knowledge and opinion of GDs and specialists regarding the role of occlusal interferences, in particular, on the development of sleep bruxism. A 13-item questionnaire was developed and mailed to all active members of the statutory dental insurance providers of the German North Rhine (n=5500; 2006 roster) and the German Westphalia-Lippe area (n=4984; 2006 roster). Group differences were statistically analyzed using chi-square tests for the qualitative variables and Mann-Whitney U tests for the quantitative variables (α=.05). Occlusal splints were by far the most frequently prescribed therapy for the management of bruxism, followed by relaxation techniques, occlusal equilibration, physiotherapy, and prosthodontic reconstruction. The occlusal stabilization splint with canine protected articulation was the splint type most often prescribed, whereas respondents used unadjusted soft splints for approximately 8% of their bruxism patients. Comparison of the opinions of all responding practicing dentists with that of experts in regard to the statement that "sleep bruxism is caused by occlusal interferences" showed a significant difference between the 2 groups (P=.021). Eighty-five percent of the experts disagreed with this statement, and only 47.7% of the practicing dentists had the same opinion as the experts. Most practicing dentists seem to concur with current scientific recommendations, and express the opinion that the management of bruxism should predominantly be conservative and reversible; however, the findings of the present survey reveal diverse

    Full Text Available BACKGROUND: The association between baseline seropositivity to human adenovirus (HAdV type 5 and increased HIV acquisition in the Step HIV Vaccine Study has raised questions concerning frequency of acquired and/or persistent Adenovirus infections among adults at high risk of HIV-1 infection. METHODOLOGY: To evaluate the frequency and pattern of HAdV shedding from the lower GI tract, we retrospectively tested rectal swabs for HAdVs in a cohort of 20 HSV-2 positive HIV-positive Peruvian men who have sex with men (MSM undergoing rectal swabbing three times/week for 18 consecutive weeks, in a prospective study of HSV-2 suppression in HIV infection. Viral DNA was extracted and amplified using a sensitive multiplex PCR assay that detects all currently recognized HAdV types. Molecular typing of viruses was performed on selected samples by hexon gene sequencing. Baseline neutralizing antibody titers to HAdVs -5, -26, -35 and -48 were also assessed. PRINCIPAL FINDINGS: 15/20 individuals had HAdV detected during follow up. The median frequency of HAdV detection was 30% of samples (range 2.0% to 64.7%. HAdV shedding typically occurred on consecutive days in clustered episodes lasting a median of 4 days (range 1 to 9 days separated by periods without shedding, suggesting frequent new infections or reactivation of latent infections over time. 8 of the 15 shedders had more than one type detected in follow-up. 20 HAdV types from species B, C, and D were identified, including HAdV-5, -26 and -48, HAdV types under development as potential vaccine candidates. 14/20 subjects were seropositive for HAdV-5; 15/20 for HAdV-26; 3/20 for HAdV-35; and 2/20 for HAdV-48. HAdV shedding did not correlate with CD4 count, plasma HIV-1 viral load, or titers to HAdV-5 or HAdV-35. The sole individual with HAdV-5 shedding was HAdV-5 seropositive. CONCLUSIONS: HAdV shedding was highly prevalent and diverse, including types presently under consideration as HIV vaccine vectors

    To conduct a systematic investigation on the prevalence, correlates, and familial aggregation of frequent nightmares in children, and to scrutinize the associations between frequent nightmares and parent-reported behavioral and mood problems in children. A cross-sectional study was conducted by collecting the data on sociodemographic, sleep, behavioral, and family-related information from a total of 6359 children (age: mean [SD]=9.2 [1.8] years; girls: 49.9%) and their reported biological parents. Community. N/A. Prevalence of frequent nightmares with a criterion of at least once per week was 5.2%. Multinomial regression analysis indicated that monthly family income, paternal and maternal nightmares, insomnia symptoms, parasomniac symptoms, and daytime consequences were significantly associated with nightmares in children. Frequent nightmares in children were significantly associated with hyper-activity (odds ratio [OR]=1.68, 95% CI 1.16-2.44), frequent temper outbursts/mood disturbance (OR=1.76, 95%CI 1.27-2.44), and poor academic performance (OR=1.62, 95% CI 1.11-2.36), after controlling for potential confounding factors. Approximately 20% of children with frequent nightmares experienced comorbid frequent insomnia. Comorbid nightmares and insomnia were associated with increased odds of hyperactivity (OR=4.13, 95% CI 2.13-8.00) and frequent temper outbursts/mood disturbance (OR=2.41, 95%CI 1.27-4.60). Frequent nightmares in children are associated with a constellation of child-, sleep-, and family-related factors, including comorbid sleep problems, such as insomnia and parasomnia, family economic status, and parental predisposition. Frequent nightmares are independently associated with emotional and behavioral problems in children.

    Membrane technology is introduced, involving the recovery of metal from wastewater after plating and of paint from wastewater after electrodeposition painting, and reuse of wastewater from buildings as water for miscellaneous use and of treated sewage for improving recreational water environments. For wastewater from planting, a recovery tank is provided right after the metal plating bath. The content of the tank is removed of organic matters by active carbon and then subjected to electrodialysis, and becomes roughly equal in concentration to what is in the plating bath. In the process of electrodeposition painting, the object to be plated is immersed in a tank and then taken out for washing in water. Paint is recovered at a rate of 98% or higher from the wastewater by a combination of ultrafiltration and reverse osmosis membranes. Wastewater from buildings after activated sludge treatment is subjected to microfiltration or ultrafiltration using membranes, to be reused for miscellaneous purposes for the building. As for treated sewage, it is further treated using a combination of microfiltration membranes, or ultrafiltration membranes, and reverse osmosis membranes for use in facilities such as artificial fountains and ponds. A recently developed bipolar membrane decomposes salts in wastewater into acids and alkalis and recover them separately, thereby enlarging the scope of wastewater from which valuables may be recovered. 11 refs., 4 figs., 4 tabs.

    1990-01-01

    The International Energy Subject Thesaurus contains the standard vocabulary to indexing terms (descriptors) developed and structured to build and maintain energy information databases. Involved in this cooperative task are (1) the technical staff of the USDOE Office of Scientific and Technical Information (OSTI) in cooperation with the member countries of the Energy Technology Data Exchange (ETDE) and (2) the International Nuclear Information System (INIS) staff representing the more than ninety countries and organizations recording and indexing information for the international nuclear information community. ETDE member countries are also members of the International Nuclear Information System (INIS). Nuclear information indexed and recorded for INIS by these ETDE member countries is also included in the ETDE Energy Data Base, and indexing terminology is therefore cooperatively standardized for use in both information systems. This structured vocabulary reflects the scope of international energy research, development, and technological programs and encompasses terminology derived not only from the basic sciences but also from the areas of energy resources, conservation, safety, environmental impact, and regulation.

  5. Naming the Ethological Subject.

    Benson, Etienne S

    2016-03-01

    Argument In recent decades, through the work of Jane Goodall and other ethologists, the practice of giving personal names to nonhuman animals who are the subjects of scientific research has become associated with claims about animal personhood and scientific objectivity. While critics argue that such naming practices predispose the researcher toward anthropomorphism, supporters suggest that it sensitizes the researcher to individual differences and social relations. Both critics and supporters agree that naming tends to be associated with the recognition of individual animal rights. The history of the naming of research animals since the late nineteenth century shows, however, that the practice has served a variety of purposes, most of which have raised few ethical or epistemological concerns. Names have been used to identify research animals who play dual roles as pets, workers, or patients, to enhance their market value, and to facilitate their identification in the field. The multifaceted history of naming suggests both that the use of personal names by Goodall and others is less of a radical break with previous practices than it might first appear to be and that the use of personal names to recognize the individuality, sentience, or rights of nonhuman animals faces inherent limits and contradictions.

  6. A Subjective Rational Choice

    Vinogradov, G. P.

    2017-01-01

    The problem of constructing a choice model of an agent with endogenous purposes of evolution is under debate. It is demonstrated that its solution requires the development of well-known methods of decision-making while taking into account the relation of action mode motivation to an agent’s ambition to implement subjectively understood interests and the environment state. The latter is submitted for consideration as a purposeful state situation model that exists only in the mind of an agent. It is the situation that is a basis for getting an insight into the agent’s ideas on the possible selected action mode results. The agent’s ambition to build his confidence in the feasibility of the action mode and the possibility of achieving the desired state requires him to use the procedures of forming an idea model based on the measured values of environment state. This leads to the gaming approach for the choice problem and its solution can be obtained on a set of trade-off alternatives.

    Full Text Available The specific aspects which determined the way some groups of students conducted their work in a university laboratory, made us understand the articulation of these groups´s dynamics, from elements that were beyond the reach of cognition. In more specific terms the conduction and the maintenance of the groups student´s dynamics were explicited based on a intergame between the non conscious strategies, shared anonymously, and the efforts of the individuals in working based on their most objective task. The results and issues we have reached so far, using a reference the work developed by W.R.Bion, with therapeutical groups, gave us the possibility for understanding the dynamics of the student´s experimental work through a new approach that approximates the fields of cognition and subjectivity. This approximation led us to a deeper reflection about the issues which may be involved in the teaching process, particularly in situations which the teacher deals with the class, organised in groups.

  8. Oncogene mutations, copy number gains and mutant allele specific imbalance (MASI frequently occur together in tumor cells.

    Junichi Soh

    Full Text Available BACKGROUND: Activating mutations in one allele of an oncogene (heterozygous mutations are widely believed to be sufficient for tumorigenesis. However, mutant allele specific imbalance (MASI has been observed in tumors and cell lines harboring mutations of oncogenes. METHODOLOGY/PRINCIPAL FINDINGS: We determined 1 mutational status, 2 copy number gains (CNGs and 3 relative ratio between mutant and wild type alleles of KRAS, BRAF, PIK3CA and EGFR genes by direct sequencing and quantitative PCR assay in over 400 human tumors, cell lines, and xenografts of lung, colorectal, and pancreatic cancers. Examination of a public database indicated that homozygous mutations of five oncogenes were frequent (20% in 833 cell lines of 12 tumor types. Our data indicated two major forms of MASI: 1 MASI with CNG, either complete or partial; and 2 MASI without CNG (uniparental disomy; UPD, due to complete loss of wild type allele. MASI was a frequent event in mutant EGFR (75% and was due mainly to CNGs, while MASI, also frequent in mutant KRAS (58%, was mainly due to UPD. Mutant: wild type allelic ratios at the genomic level were precisely maintained after transcription. KRAS mutations or CNGs were significantly associated with increased ras GTPase activity, as measured by ELISA, and the two molecular changes were synergistic. Of 237 lung adenocarcinoma tumors, the small number with both KRAS mutation and CNG were associated with shortened survival. CONCLUSIONS: MASI is frequently present in mutant EGFR and KRAS tumor cells, and is associated with increased mutant allele transcription and gene activity. The frequent finding of mutations, CNGs and MASI occurring together in tumor cells indicates that these three genetic alterations, acting together, may have a greater role in the development or maintenance of the malignant phenotype than any individual alteration.

    Park, Mi Kyong; Satoh, Noriaki; Kumashiro, Masaharu

    2008-07-01

    The aim of this study is to examine the relationship between mental workload and occurrence of hot flashes. Twelve women with moderate to severe menopausal hot flashes participated in the study. Subjects participated in both a mental arithmetic task (Task) and control (Non-task) experiments. We measured heart rate, heart rate variability, blood pressure, near infrared spectroscopy, skin temperature, and skin potential level. The incidence of hot flashes was greater in Task than in Non-task. No significant differences between before, during and after hot flashes emerged for the percentage of correct responses and reaction time. However, the percentage of correct responses for two subjects among the ten who experienced hot flashes in Task substantially declined during hot flashes. Chest skin temperatures increased in both Task and Non-task during hot flashes, and regional oxygen saturation was significantly higher in Non-task than in Task. The present study suggested that mental workload under time pressure might be a risk factor for menopausal hot flashes, and the performance of most people who experienced hot flashes was not affected by hot flashes, however, work-related difficulties due to cognitive disturbance during hot flashes might arise in some people.

  12. High frequent total station measurements for the monitoring of bridge vibrations

    Lienhart, Werner; Ehrhart, Matthias; Grick, Magdalena

    2017-03-01

    Robotic total stations (RTS) are frequently used for the measurement of temperature induced bridge deformations or during load testing of bridges. In experimental setups, total stations have also been used for the measurement of dynamic bridge deformations. However, with standard configurations the measurement rate is not constant and on average an update rate of 7-10Hz can be achieved. This is not sufficient for the vibration monitoring of bridges considering their natural frequencies which are also in the same range. In this paper, we present different approaches to overcome these problems. In the first two approaches we demonstrate how the measurement rate to prisms can be increased to 20Hz to determine vertical deformations of bridges. Critical aspects like the measurement resolution of the automated target tracking and the correct sequence of steering commands are discussed. In another approach we demonstrate how vertical bridge vibrations can be measured using an image assisted total station (IATS) and corresponding processing techniques. The advantage of image-based methods is that structural features of a bridge like bolts can be used as targets. Therefore, no expensive prisms have to be mounted and access to the bridge is not required. All approaches are verified by laboratory investigations and their suitability is proven in a field experiment on a 74m long footbridge. In this field experiment the natural frequencies derived from the total station measurements are compared to the results of accelerometer measurements.

  13. ACME: A scalable parallel system for extracting frequent patterns from a very long sequence

    KAUST Repository

    Sahli, Majed

    2014-10-02

    Modern applications, including bioinformatics, time series, and web log analysis, require the extraction of frequent patterns, called motifs, from one very long (i.e., several gigabytes) sequence. Existing approaches are either heuristics that are error-prone, or exact (also called combinatorial) methods that are extremely slow, therefore, applicable only to very small sequences (i.e., in the order of megabytes). This paper presents ACME, a combinatorial approach that scales to gigabyte-long sequences and is the first to support supermaximal motifs. ACME is a versatile parallel system that can be deployed on desktop multi-core systems, or on thousands of CPUs in the cloud. However, merely using more compute nodes does not guarantee efficiency, because of the related overheads. To this end, ACME introduces an automatic tuning mechanism that suggests the appropriate number of CPUs to utilize, in order to meet the user constraints in terms of run time, while minimizing the financial cost of cloud resources. Our experiments show that, compared to the state of the art, ACME supports three orders of magnitude longer sequences (e.g., DNA for the entire human genome); handles large alphabets (e.g., English alphabet for Wikipedia); scales out to 16,384 CPUs on a supercomputer; and supports elastic deployment in the cloud.

    Full Text Available Abstract Much literature on electronic government services research could be found on adoptability issues from government and service providers point of view. Many studies have looked into adoptability factors from user perspectives and majority captured adoptability perspectives of frequent Internet users the ones who use Internet applications for more than 10 hours a week. On the contrary the perspectives of majority of Pakistani users which use Internet applications for less than 10 hours per week are never inquired. This paper tries to fill this gap by looking into electronic government adoptability perspectives and expectations of such Internet users of Pakistan which are much greater in numbers than others. An amended UTAUT model with all its moderators is used in this study and the results demonstrate that performance level ease of effort and social influence strongly effect behavioral intention of users in using electronic government services in Pakistan. The individuals behavioral intention along with presence of appropriate facilitating conditions triggers use behavior of users. The results show that only gender moderates majority of UTAUT relationships and accordingly a modified UTAUT model is presented. The paper provides certain insights for people making policies and academicians for performing further research while it stresses for service proliferation with special attention towards female population.

  15. Sialorrhoea: How to Manage a Frequent Complication of Motor Neuron Disease

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Sialorrhoea, the unintentional loss of saliva through the mouth, is the frequent complication of neurological disorders affecting strength or coordination of oropharyngeal muscles, such as motor neuron disease/amyotrophic lateral sclerosis (MND/ALS or Parkinson’s disease. Sialorrhoea might affect up to 42% of ALS patients, with almost half of them having poorly managed symptoms. Sialorrhoea can impair patients’ social life, while dermatological complications, such as skin rashes, may arise due to constant exposure to moisture. Moreover, the excess mouth-retained saliva in ALS patients may lead to serious complications, such as choking, which causes anxiety, and aspiration with the consequent pneumonia. The inclusion of a sialorrhoea-related item in the ALS functional rating scale testifies both the incidence and importance of sialorrhoea during the ALS clinical course. Because of the progressive nature of ALS, presence and severity of sialorrhoea should be assessed at every visit and, when present, active treatment pursued. Available treatments include behavioural therapy, i.e. techniques to enhance periodic swallowing of saliva, systemic or local anticholinergic medications, botulinum toxin injection, electron beam irradiation, and surgical techniques. This review paper briefly describes the available options with related side-effects and current guideline recommendations for managing sialorrhoea in ALS patients.

    This study aims to investigate pollen, mite and mold sensitivities among children with frequent respiratory tract infection living in damp apartments and to evaluate the effects of separated parents, education status, ethnicity, the presence of siblings, and their atopy status on the development of atopy. Between June 2012 and September 2013, 63 children (28 girls, 35 boys; mean age 80.2 years; range 24 to 97 years) who were admitted to Acıbadem Bodrum Hospital with at least six respiratory tract infection per year with mold exposure and prolonged cough attacks and underwent skin prick test (SPT) were included. Skin prick test-positive patients were further divided into groups according to the upper respiratory tract (URT) or lower respiratory tract (LRT) involvement and were assessed for mold, mite and pollen sensitivities. One-third of the patients were SPT positive. The parents of these patients had physician-diagnosed allergy (pmold sensitivity presented with LRT findings (pmolds than non-atopic children. Mold exposure may also cause inflammation at LRT without causing immunoglobulin E-dependent sensitization.

    The use of health services has seen a steep rise. The frequent users are responsible for significant economic, human and social impact. The objective is to analyze the characteristics of frequent attenders in our Health Center, in order to evaluate the possibility of taking corrective measures to improve the quality of care and efficiency in the use of resources. Descriptive observational study of a sample of 379 patients over 18 years old. The dependent variables were attendance (number of visits to their family doctor during the previous year), frequent attendance (10 or more visits to the family doctor in the last year), and persistent frequent attenders (10 or more visits to the family doctor in each of the last two years). Data were collected from medical records and by telephone interview. The mean attendance was 6.83 (95%CI: 6.13-7.53), frequent attendance reached 25.4% (95%CI: 21.4-29.6), and persistent frequent attenders, 1.6% (95%CI: 0.5-2.9). Frequent attendance was associated with sex, age, marital status, educational level, family structure, existence of chronic disease, use of anxiolytic and antidepressants, request for additional tests, and referrals to other specialists, proximity to the health center, and level of satisfaction with their family doctor. The low persistent frequent attenders found suggests that frequent attendance could be largely due to factors related to professional and organization. Studies are required to address the high level of consumption of psychotropic drugs, and improving professional skills in dealing with mental problems.

    Nurses can become demoralized and hostile toward frequent visitors in psychiatric emergency rooms because of the number of visits. The aim of this study was to develop more knowledge about the ways in which nurses categorize frequent visitors. Eleven nurses were interviewed, and their categorizing...... through the emergency room and/or there was poor rapport with the nurses....... practices were examined from a social constructionist perspective. The results showed that the nurses did not categorize frequent visitors as particularly unlikeable or difficult to treat. Like other visitors, they could be categorized as difficult if they obstructed a smooth flow of successful referrals...

    Subjective tinnitus is frequently seen in the general population. We investigated the personality traits in tinnitus and nontinnitus groups, both of which were nonpsychiatric. In this study, we evaluated 28 patients with subjective tinnitus and 28 subjects for a control group. In the analysis of psychiatric status, Minnesota Multiphasic Personality Inventory (MMPI) profiles were used. Psychasthenia was found to be higher in tinnitus patients of both sexes, whereas Hypochondriasis, Hysteria, Masculinity/Feminity, Psychasthenia, Schizophrenia, and Social Introversion scores were higher in females with tinnitus. In our research, it is thought that the experience of tinnitus may cause the psychological disturbance.

    To estimate the frequency of painful physical symptoms (PPS) in elderly subjects (≥ 65 years) with major depressive disorder (MDD) in real-world clinical conditions and to establish whether PPS are associated with poor depression outcomes, including more severe depression and worse health-related quality of life (HRQoL). Observational studies of MDD that included assessment of PPS and elderly subjects were screened. Measures of PPS were based on the Somatic Symptom Inventory (SSI) or Visual Analogue Scale (VAS). Data from a variety of depressive symptom severity and HRQoL scales were used. Analysis cohorts were based on age [aged ≥ 65 years (elderly) or elderly subjects. Data from seven studies (representing 26 countries) were collated. Of the 11,477 subjects, 14% were aged ≥ 65 years and 71% were classified as having PPS (PPS+). PPS were more frequent in elderly subjects (74% vs. 70% of younger subjects) and were positively associated with being female and Hispanic, and negatively associated with being East Asian in the elderly. The presence of PPS was associated with more severe clinical symptomatology and comparatively poorer HRQoL in elderly subjects. PPS, although frequent in younger MDD patients, were slightly more frequent in elderly MDD patients and associated with comparatively poorer clinical and functional outcomes. As elderly patients report somatic symptoms more readily than emotional symptoms, physicians should consider depression in addition to physical causes when PPS are present. © 2012 Blackwell Publishing Ltd.

    Full Text Available BACKGROUNDS: With 10% of the general population aged 15-59 years chronically infected with hepatitis C virus (HCV, Egypt is the country with the highest HCV prevalence worldwide. Healthcare workers (HCWs are therefore at particularly high risk of HCV infection. Our aim was to study HCV infection risk after occupational blood exposure among HCWs in Cairo. METHODOLOGY/PRINCIPAL FINDINGS: The study was conducted in 2008-2010 at Ain Shams University Hospital, Cairo. HCWs reporting an occupational blood exposure at screening, having neither anti-HCV antibodies (anti-HCV nor HCV RNA, and exposed to a HCV RNA positive patient, were enrolled in a 6-month prospective cohort with follow-up visits at weeks 2, 4, 8, 12 and 24. During follow-up, anti-HCV, HCV RNA and ALT were tested. Among 597 HCWs who reported a blood exposure, anti-HCV prevalence at screening was 7.2%, not different from that of the general population of Cairo after age-standardization (11.6% and 10.4% respectively, p = 0.62. The proportion of HCV viremia among index patients was 37%. Of 73 HCWs exposed to HCV RNA from index patients, nine (12.3%; 95%CI, 5.8-22.1% presented transient viremia, the majority of which occurred within the first two weeks after exposure. None of the workers presented seroconversion or elevation of ALT. CONCLUSIONS/SIGNIFICANCE: HCWs of a general University hospital in Cairo were exposed to a highly viremic patient population. They experienced frequent occupational blood exposures, particularly in early stages of training. These exposures resulted in transient viremic episodes without established infection. These findings call for further investigation of potential immune protection against HCV persistence in this high risk group.

    The clinical features and management of severe hypertension (HT) (blood pressure > 99th percentile + 5 mm Hg) have been rarely described in pediatric oncology. Retrospective descriptive study of the case files of 31 patients followed in the Institut Curie Department of Pediatric Oncology between 1999 and 2004 and presenting severe HT at the time of diagnosis of their tumor. The median age was 2 years 1 month (range: 3 mo to 6 y 8 mo). Median blood pressure was 99th percentile + 30 mm Hg (range: 99th percentile + 7 mm Hg to 99th percentile + 62 mm Hg). The tumors presented by these children were: Wilms tumor (n=17, ie, 20% of all Wilms tumors treated during this period), neuroblastoma (n=12, ie, 10% of all neuroblastomas treated during this period) or other tumors (n=2). HT was asymptomatic in all children. Initial management consisted of etiologic treatment by primary chemotherapy and/or surgical resection of the tumor, associated with antihypertensive therapy, initially administered by intravenous injection for 12 children (nicardipine, labetalol) and then orally in all children (calcium channel blockers, n=23; angiotensin-converting enzyme inhibitor, n=16; beta-blockers, n=4; alpha/beta-blockers, n=2; diuretics, n=1). Dual therapy was necessary in 7 cases and triple therapy was necessary in 1 case. The median duration of antihypertensive therapy was 40 days (range: 9 to 195). No child developed a serious complication of HT. Initial HT is a frequent complication of Wilms tumor and neuroblastoma and affects young children (< 2.5 y). It is often severe, asymptomatic, but needs specific treatment and resolves after treatment of the tumor.

  14. Subjective wellbeing, health, and ageing.

    Steptoe, Andrew; Deaton, Angus; Stone, Arthur A

    2015-02-14

    Subjective wellbeing and health are closely linked to age. Three aspects of subjective wellbeing can be distinguished-evaluative wellbeing (or life satisfaction), hedonic wellbeing (feelings of happiness, sadness, anger, stress, and pain), and eudemonic wellbeing (sense of purpose and meaning in life). We review recent advances in the specialty of psychological wellbeing, and present new analyses about the pattern of wellbeing across ages and the association between wellbeing and survival at older ages. The Gallup World Poll, a continuing survey in more than 160 countries, shows a U-shaped relation between evaluative wellbeing and age in high-income, English speaking countries, with the lowest levels of wellbeing in ages 45-54 years. But this pattern is not universal. For example, respondents from the former Soviet Union and eastern Europe show a large progressive reduction in wellbeing with age, respondents from Latin America also shows decreased wellbeing with age, whereas wellbeing in sub-Saharan Africa shows little change with age. The relation between physical health and subjective wellbeing is bidirectional. Older people with illnesses such as coronary heart disease, arthritis, and chronic lung disease show both increased levels of depressed mood and impaired hedonic and eudemonic wellbeing. Wellbeing might also have a protective role in health maintenance. In an analysis of the English Longitudinal Study of Ageing, we identify that eudemonic wellbeing is associated with increased survival; 29·3% of people in the lowest wellbeing quartile died during the average follow-up period of 8·5 years compared with 9·3% of those in the highest quartile. Associations were independent of age, sex, demographic factors, and baseline mental and physical health. We conclude that the wellbeing of elderly people is an important objective for both economic and health policy. Present psychological and economic theories do not adequately account for the variations in patterns

  18. An Efficient Approach to Mining Maximal Contiguous Frequent Patterns from Large DNA Sequence Databases

    Directory of Open Access Journals (Sweden)

    Md. Rezaul Karim

    2012-03-01

    Full Text Available Mining interesting patterns from DNA sequences is one of the most challenging tasks in bioinformatics and computational biology. Maximal contiguous frequent patterns are preferable for expressing the function and structure of DNA sequences and hence can capture the common data characteristics among related sequences. Biologists are interested in finding frequent orderly arrangements of motifs that are responsible for similar expression of a group of genes. In order to reduce mining time and complexity, however, most existing sequence mining algorithms either focus on finding short DNA sequences or require explicit specification of sequence lengths in advance. The challenge is to find longer sequences without specifying sequence lengths in advance. In this paper, we propose an efficient approach to mining maximal contiguous frequent patterns from large DNA sequence datasets. The experimental results show that our proposed approach is memory-efficient and mines maximal contiguous frequent patterns within a reasonable time.

    In cross-sectional studies, psychological distress has been associated with frequent health care utilization. However, there is a need for prospective studies to confirm these findings. This cohort study evaluated whether psychological distress predicted frequent attendance in family practice....... In 1990, 185 consecutive adults who consulted their primary care physician (PCP) about an illness were rated on two psychometric scales (Hopkins Symptom Check List [SCL-8] and Whiteley-7), and their annual number of face-to-face contacts with a family practice was followed until 1996. Frequent attenders.......16 [0.99-1.36] for SCL and OR 1.31 [1.05-1.65] for Whiteley). Psychological distress involved an increased risk of future frequent attendance among adult patients consulting family practice in the daytime about an illness....

  3. Mirrored prominent deck B phenomenon: frequent small losses override infrequent large gains in the inverted Iowa Gambling Task.

    Directory of Open Access Journals (Sweden)

    Ching-Hung Lin

    Full Text Available Since Bechara et al. pioneered its development, the Iowa Gambling Task (IGT has been widely applied to elucidate decision behavior and medial prefrontal function. Although most decision makers can hunch the final benefits of IGT, ventromedial prefrontal lesions generate a myopic choice pattern. Additionally, the Iowa group developed a revised IGT (inverted IGT, iIGT to confirm the IGT validity. Each iIGT trial was generated from the trial of IGT by multiplying by a "-" to create an inverted monetary value. Thus, bad decks A and B in the IGT become good decks iA and iB in the iIGT; additionally, good decks C and D in the IGT become bad decks iC and iD in the iIGT. Furthermore, IGT possessed mostly the gain trials, and iIGT possessed mainly the loss trials. Therefore, IGT is a frequent-gain-based task, and iIGT is a frequent-loss-based task. However, a growing number of IGT-related studies have identified confounding factors in IGT (i.e., gain-loss frequency, which are demonstrated by the prominent deck B phenomenon (PDB phenomenon. Nevertheless, the mirrored PDB phenomenon and guiding power of gain-loss frequency in iIGT have seldom been reexamined. This experimental finding supports the prediction based on gain-loss frequency. This study identifies the mirrored PDB phenomenon. Frequent small losses override occasional large gains in deck iB of the iIGT. Learning curve analysis generally supports the phenomenon based on gain-loss frequency rather than final outcome. In terms of iIGT and simple versions of iIGT, results of this study demonstrate that high-frequency loss, rather than a satisfactory final outcome, dominates the preference of normal decision makers under uncertainty. Furthermore, normal subjects prefer "no immediate punishment" rather than "final reward" under uncertainty.

    2016-10-01

    The presence of coronary artery ectasia (CAE) is influenced by genetic factors and related to the presence of aneurysms in other vascular beds. Bicuspid aortic valve (BAV) disease is frequently accompanied by ascending aortic aneurysm. Because the aortic valve and the proximal parts of the coronary arteries share a common embryonic origin, we hypothesized that CAE is associated with BAV disease. One hundred seventy-seven patients with suspected aortic valve disease (n=94 BAV, n=83 tricuspid aortic valve) underwent both cardiac magnetic resonance imaging and coronary angiography. To confirm the association of CAE with BAV, the frequency of CAE was evaluated in an in-house BAV registry (n=600, n=231 with available coronary angiogram) and compared with the frequency of CAE in the German Myocardial Infarction (MI) Family Study, in which the heritability of CAE was formerly established (n=899). Furthermore, the frequency of CAE was investigated in an observational registry of real-life patients undergoing coronary angiography for clinically indicated reasons (n=3.097) and in a subgroup of the KORA MI study (Cooperative Health Research in the Region of Augsburg), which is a population-based MI registry (n=403).Compared with tricuspid aortic valve disease, CAE occurred more than twice as frequently in cardiac magnetic resonance-confirmed BAV disease (17% versus 44%; P<0.0001) and CAE was observed similarly often in subjects with BAV with (37%) and without (54%, P=0.11) ascending aortic pathology. The common appearance of CAE in patients with BAV could be independently confirmed in the BAV registry (frequency 37%), whereas CAE was found less frequently in family history of positive MI patients (21%), sporadic MI without familial disposition (10%), and rarely in unrelated real-life catheterization patients (6%). To our knowledge, our data show for the first time that ectatic coronary artery disease is a common appearance of BAV disease with and without ascending aortic

  5. Population structure of Pseudomonas aeruginosa from five Mediterranean countries: evidence for frequent recombination and epidemic occurrence of CC235.

    Full Text Available Several studies in recent years have provided evidence that Pseudomonas aeruginosa has a non-clonal population structure punctuated by highly successful epidemic clones or clonal complexes. The role of recombination in the diversification of P. aeruginosa clones has been suggested, but not yet demonstrated using multi-locus sequence typing (MLST. Isolates of P. aeruginosa from five Mediterranean countries (n = 141 were subjected to pulsed-field gel electrophoresis (PFGE, serotyping and PCR targeting the virulence genes exoS and exoU. The occurrence of multi-resistance (≥ 3 antipseudomonal drugs was analyzed with disk diffusion according to EUCAST. MLST was performed on a subset of strains (n = 110 most of them had a distinct PFGE variant. MLST data were analyzed with Bionumerics 6.0, using minimal spanning tree (MST as well as eBURST. Measurement of clonality was assessed by the standardized index of association (I(A (S. Evidence of recombination was estimated by ClonalFrame as well as SplitsTree4.0. The MST analysis connected 70 sequence types, among which ST235 was by far the most common. ST235 was very frequently associated with the O11 serotype, and frequently displayed multi-resistance and the virulence genotype exoS⁻/exoU⁺. ClonalFrame linked several groups previously identified by eBURST and MST, and provided insight to the evolutionary events occurring in the population; the recombination/mutation ratio was found to be 8.4. A Neighbor-Net analysis based on the concatenated sequences revealed a complex network, providing evidence of frequent recombination. The index of association when all the strains were considered indicated a freely recombining population. P. aeruginosa isolates from the Mediterranean countries display an epidemic population structure, particularly dominated by ST235-O11, which has earlier also been coupled to the spread of ß-lactamases in many countries.

    Frequent admitters to hospitals are high-cost patients who strain finite healthcare resources. However, the exact risk factors for frequent admissions, which can be used to guide risk stratification and design effective interventions locally, remain unknown. Our study aimed to identify the clinical and sociodemographic risk factors associated with frequent hospital admissions in Singapore. An observational study was conducted using retrospective 2014 data from the administrative database at Singapore General Hospital, Singapore. Variables were identified a priori and included patient demographics, comorbidities, prior healthcare utilisation, and clinical and laboratory variables during the index admission. Multivariate logistic regression analysis was used to identify independent risk factors for frequent admissions. A total of 16,306 unique patients were analysed and 1,640 (10.1%) patients were classified as frequent admitters. On multivariate logistic regression, 16 variables were independently associated with frequent hospital admissions, including age, cerebrovascular disease, history of malignancy, haemoglobin, serum creatinine, serum albumin, and number of specialist outpatient clinic visits, emergency department visits, admissions preceding index admission and medications dispensed at discharge. Patients staying in public rental housing had a 30% higher risk of being a frequent admitter after adjusting for demographics and clinical conditions. Our study, the first in our knowledge to examine the clinical risk factors for frequent admissions in Singapore, validated the use of public rental housing as a sensitive indicator of area-level socioeconomic status in Singapore. These risk factors can be used to identify high-risk patients in the hospital so that they can receive interventions that reduce readmission risk.

    Sjögren's Syndrome (SS) is an autoimmune pathology of varying prevalence. Its involvement in exocrine glands requires that greater attention be paid to patients' oral health. A cross-sectional study was designed to assess the oral health of subjects with SS in constant medical follow-ups. Variables such as the presence of periodontal infections, decay and alterations in the oral mucosa were analyzed, and the individual's salivary flow was measured. The data were analyzed descriptively and with the chi-squared test, considering pdental check-up every 6 months in only 9% of cases, whereas the rest had one every 1 or 2 years. All the subjects recounted presenting with dry mouth and associated significantly the ingestion of fluids and teeth brushing to improve the sensation of dryness. The salivary flow was objectively seen to be compromised, showing a significant reduction in those with more time since diagnosis of the disease; more than 90% of subjects exhibited periodontal inflammation and a high level of caries. The mucosa presented a low level of pathology. In conclusion, education in oral health is imperative for subjects with this pathology and more frequent check-ups may be useful in decreasing the levels of oral pathology.

    The long-term outcome of athletes with frequent ventricular premature complexes (VPCs) and apparently normal heart has not been fully clarified. To evaluate the clinical and prognostic significance of VPCs and the influence of continuing sports activity during follow-up, we studied 120 healthy athletes (96 men; median age 16 years) in whom frequent VPCs (>100 VPCs/24 hours) were discovered by chance during preparticipation screening. All athletes were followed up for a median of 84 months. During follow-up, 96 underwent serial 24-hour Holter recording and 62 underwent serial echocardiography. The median number of VPCs/24 hours on basal Holter was 3,760. During follow-up, 81 athletes continued sports activity, whereas 39 did not. No athlete died or developed overt heart disease. The median number of VPCs/24 hours decreased in both athletes who continued sports activity and those who did not (from 3,805 to 1,124, p sporting activity does not modify this benign outcome, (3) during follow-up, the burden of VPCs decreases whether or not subjects continue sports activity, and (4) in 14.5% of athletes, ejection fraction slightly decreases over time.

    Full Text Available It is perceived that patients with a history of frequent alcohol consumption require more opioids for postoperative pain control and experience less postoperative nausea and vomiting than patients without such a history. However, there is scarce evidence supporting this notion. The aim of this study was to assess association between frequent alcohol consumption and opioid requirement for postoperative pain control and occurrence of postoperative nausea and vomiting.The medical records for 4143 patients using intravenous patient-control analgesia with opioids after abdominal surgery between January 2010 and September 2013 were obtained, and associations were sought between the cumulative opioid consumption (in intravenous morphine equivalence per body weight (mg/kg in the first 2 days after abdominal operation and several demographic and clinical variables by multiple regression analysis. The association between the occurrence of postoperative nausea and vomiting and several demographic and clinical variables was also sought by multiple logistic regression analysis.Frequent alcohol drinking, among other previously reported factors, was associated with increased opioid consumption for postoperative pain control (p < 0.001. The estimate effect of frequent alcohol drinking was 0.117 mg/kg. Frequent alcohol drinking was also associated with decreased risks of postoperative nausea (odds ratio = 0.59, p = 0.003 and vomiting (odds ratio = 0.49, p = 0.026.Frequent alcohol drinking was associated with increased opioid consumption for postoperative pain control and decreased risks of postoperative nausea and vomiting after abdominal surgery.

    Hyponatraemia is the most common electrolyte disturbance encountered in clinical practice. It is associated with -significant morbidity and mortality, thus appropriate investigation and treatment is essential. Hyponatraemia presents with a spectrum of clinical presentations ranging from no symptoms to life-threatening neurological sequelae. Hyponatraemia has multiple aetiologies and distinguishing the underlying aetiology facilitates appropriate treatment. This review provides an overview of the presentations and approaches to management of this common clinical condition. © Royal College of Physicians 2017. All rights reserved.

    2013-01-01

    Objective: The goal of this study was to examine the clinical presentation of chronic traumatic encephalopathy (CTE) in neuropathologically confirmed cases. Methods: Thirty-six adult male subjects were selected from all cases of neuropathologically confirmed CTE at the Boston University Center for the Study of Traumatic Encephalopathy brain bank. Subjects were all athletes, had no comorbid neurodegenerative or motor neuron disease, and had next-of-kin informants to provide retrospective reports of the subjects' histories and clinical presentations. These interviews were conducted blind to the subjects' neuropathologic findings. Results: A triad of cognitive, behavioral, and mood impairments was common overall, with cognitive deficits reported for almost all subjects. Three subjects were asymptomatic at the time of death. Consistent with earlier case reports of boxers, 2 relatively distinct clinical presentations emerged, with one group whose initial features developed at a younger age and involved behavioral and/or mood disturbance (n = 22), and another group whose initial presentation developed at an older age and involved cognitive impairment (n = 11). Conclusions: This suggests there are 2 major clinical presentations of CTE, one a behavior/mood variant and the other a cognitive variant. PMID:23966253

    The mode of presentation of patients with celiac disease has changed dramatically over the recent decades, with diarrheal or classic presentations becoming less common. This trend is most markedly seen in children, whose main presentations include recurrent abdominal pain, growth issues, and screening groups at risk. Among adults, presentations include diarrhea, anemia, osteoporosis, and recognition at endoscopy performed for gastroesophageal reflux disease, as well as screening. The groups most commonly screened include family members of patients with celiac disease, Down syndrome, and autoimmune diseases. Copyright © 2012. Published by Elsevier Inc.

    Polydipsia and water intoxication (PWI) are relatively frequent among schizophrenic subjects, particularly in institutional settings and may lead to severe complications. However, little is known on their association with other characteristics of psychosis. Hence, we took advantage of a cohort of 114 subjects extensively assessed on natural history and clinical variables to examine the correlates of PWI in chronic schizophrenia. We randomly sampled DSM-IV schizophrenic subjects from: i) a lower functioning subgroup, i.e., long-term psychiatric wards or highly structured group housing facilities; and ii) a higher functioning subgroup, i.e., patients living in the community without supervision. Subjects were assessed from multiple sources for lifetime severity of positive, disorganisation, negative and depressive symptoms, premorbid adjustment, age of onset, level of functioning, comorbid diagnoses of substance abuse and lifetime history of PWI. Twelve subjects (10.5%) met our PWI criteria. We observed more severe psychotic symptoms, earlier onset, poorer current adjustment and more frequent prior alcohol use disorder in PWI subjects. When restricting comparisons to patients living in institutional setting, differences on clinical and natural history variables vanished but the association between PWI and prior alcohol abuse persisted (72.7% in PWI vs. 21.4% in non-PWI subjects, pPWI by a mean of 12.8 years. PWI schizophrenic subjects are characterized by a non-specific greater severity on a broad array of clinical and natural history variables and by a specific association with prior alcohol abuse. Thus, our data suggest that a greater severity of illness and a prior history of alcohol use disorders interact in increasing the risk of developing PWI in chronic schizophrenic patients.

    The male to female ratio in autism is 4:1 in the global autistic population, but increases to 23:1 in autistic subjects without physical or brain abnormalities.(1) Despite this well-recognised gender difference, male predisposition to autistic disorder remains unexplained and the role of sex chromosomes is still debated. Numerical and structural abnormalities of the sex chromosomes are among the most frequently reported chromosomal disorders associated with autism. However, genome scans have failed to detect linkage on the X chromosome(2,3,4) and this approach cannot study the non-recombining region of the Y chromosome. In this study, we searched for a specific Y chromosome effect in autistic subjects. Using informative Y-polymorphic markers, the Y chromosome haplotypes of 111 autistic subjects from France, Sweden and Norway were defined and compared with relevant control populations. No significant difference in Y-haplotype distribution between the affected and control groups was observed. Although this study cannot exclude the presence of a Y susceptibility gene, our results are not suggestive of a Y chromosome effect in autism.

    Full Text Available The rapid development of information technology has enabled the creation of entirely new presentation frameworks and this article will attempt to explore the subject of on-site presentation of archaeological sites. The most frequently used environment currently has been in the form of a variety of virtual museums that are accessible on the Internet; in essence these keep their visitors stuck in front of a PC monitor. One option that allows leaving the monitor and stepping directly out-of-doors into a virtual open-air museum is by means of applications for mobile phones. Terms such as 'virtual' or 'augmented reality' no longer represent a million light-years away science-fiction concepts, but rather a new tool for public archaeology and for the preservation of the archaeological heritage. This article presents several projects that have been implemented by the Archaeological Institute in Prague, who, by using mobile applications, built virtual open-air museums directly in the locations of archaeological excavations.

    This viewgraph document describes the data mining system developed at NASA Ames. Many NASA programs have large numbers (and types) of problem reports.These free text reports are written by a number of different people, thus the emphasis and wording vary considerably With so much data to sift through, analysts (subject experts) need help identifying any possible safety issues or concerns and help them confirm that they haven't missed important problems. Unsupervised clustering is the initial step to accomplish this; We think we can go much farther, specifically, identify possible recurring anomalies. Recurring anomalies may be indicators of larger systemic problems. The requirement to identify these anomalies has led to the development of Recurring Anomaly Discovery System (ReADS).

    Absorption of irrigation fluid was not detected during GreenLight™ laser vaporization of the prostate using the first generation 80 W laser. However, data are lacking on intraoperative irrigation fluid absorption using the second generation 120 W high power laser. We assessed whether fluid absorption occurs during high power laser vaporization of the prostate. We performed this prospective investigation at a tertiary referral center in patients undergoing 120 W laser vaporization for prostatic bladder outlet obstruction. Normal saline containing 1% ethanol was used for intraoperative irrigation. The expired breath ethanol concentration was measured periodically during the operation using an alcometer. The volume of saline absorption was calculated from these concentrations. Intraoperative changes in hematological and biochemical blood parameters were also recorded. Of 50 investigated patients 22 (44%) had a positive breath ethanol test. Median absorption volume in the absorber group was 725 ml (range 138 to 3,452). Ten patients absorbed more than 1,000 ml. Absorbers had a smaller prostate, more capsular perforation, higher bleeding intensity and more laser energy applied during the operation. Three patients (13%) had symptoms potentially related to fluid absorption. Hemoglobin, hematocrit and serum chloride were the only blood parameters that changed significantly in the absorber group. The changes were significantly different than those in nonabsorbers. Fluid absorption occurs frequently during high power laser vaporization of the prostate. This should be considered in patients who present with cardiopulmonary or neurological symptoms during or after the procedure.

    Full Text Available "nBackground: MSCs have been isolated from a variety of mammals by the plastic adherence method. However, this method can be problematic due to the unwanted growth of hematopoietic cells and non-MSCs. The potential of MSCs to differentiate along multiple lineages is the key to the identification of stem cell populations in the absence of molecular markers. In the present study, we describe a homogeneous population of MSCs from mouse bone marrow isolated using an improved plastic adherence method that employs frequent medium change (FMC at the initial hours of harvested bone marrow cell culture."n"nMethods: Balb/c mice were sacrificed and whole bone marrow cells were aspirated from the femur and tibia and then cultivated in six-well plates. After 3-4 hours of culture, old medium was removed and fresh medium was added. FMC was performed every eight hours over a 72 hour period. When primary cultures became nearly confluent, the first passage was performed. These cells were then used for further examination. To investigate their mesenchymal nature, the cells were allowed to differentiate into mesenchymal lineages and examined at each passage up to the tenth passage for surface antigens by flow cytometry."n"nResults: We achieved purified populations of fibroblast-like cells in the two weeks after culture initiation. The cells were capable of differentiating into osteocytes and adipocytes. Isolated MSCs were reactive to the CD44, Sca-1, and CD90 cell surface markers. MSCs were negative for hematopoietic surface markers such as CD34, CD11b, CD45, CD31, CD106, CD117 and CD135."n"nConclusions: This protocol provides an efficient isolation of homogeneous populations of MSCs from mouse bone marrow.

    Full Text Available Purpose: The present study aimed at clinical and pulmonary functions profiling of patients with chronic obstructive pulmonary disease (COPD to anticipate future exacerbations. Methods: The study included 80 COPD patients; 40 patients had ≥2 acute exacerbations during preceding 1 year (frequent exacerbation [FECOPD] group and 40 patients had <2 acute exacerbations during preceding 1 year (infrequent exacerbation [I-FECOPD] group. Clinical profile, sputum microbiology, blood gas analysis, spirometric indices, and diffusion capacity (transfer test variables were assessed. Groups' comparison was performed using an independent t-test for numeric scale parameters and Chi-square test for nominal parameters. Pearson's and Spearman's correlation coefficients were derived for numeric scale parameters and numeric nominal parameters, respectively. Multinomial logistic regression analysis was done using SPSS software. Results: FECOPD group contained younger patients than in I-FECOPD group although the difference was not statistically significant. There was no significant difference between two groups regarding smoking pack-years and duration of illness. FECOPD group had significantly more expectoration score and Modified Medical Research Council dyspnea scores. Cough score and wheeze score did not differ significantly between two groups. More patients in FECOPD group (12/40 vs. 4/40 had lower airway bacterial colonization. Arterial blood gas parameters were more deranged in FECOPD group. Spirometric indices (forced expiratory volume during 1st s as well as transfer test (both diffusing capacity for carbon monoxide and transfer coefficient of the lung values were significantly reduced in FECOPD group. Conclusions: The patients in FECOPD group had clinical, spirometric, and transfer test profiling suggestive of a severe COPD phenotype, the recognition will help in predicting future exacerbations and a better management.

    The use of computer vision technology in collecting and analyzing statistics during sports matches or training sessions is expected to provide valuable information for tactics improvement. However, the measurements published in the literature so far are either unreliably documented to be used in training planning due to their limitations or unsuitable for studying high-speed motion in large area with frequent occlusions. A sports annotation system is introduced in this paper for tracking high-speed non-rigid human motion over a large playing area with the aid of motion camera, taking short track speed skating competitions as an example. The proposed system is composed of two sub-systems: precise camera motion compensation and accurate motion acquisition. In the video registration step, a distinctive invariant point feature detector (probability density grads detector) and a global parallax based matching points filter are used, to provide reliable and robust matching across a large range of affine distortion and illumination change. In the motion acquisition step, a two regions' relationship constrained joint color model and Markov chain Monte Carlo based joint particle filter are emphasized, by dividing the human body into two relative key regions. Several field tests are performed to assess measurement errors, including comparison to popular algorithms. With the help of the system presented, the system obtains position data on a 30 m × 60 m large rink with root-mean-square error better than 0.3975 m, velocity and acceleration data with absolute error better than 1.2579 m s-1 and 0.1494 m s-2, respectively.

    Intraoperative monitoring (IOM) is an essential method for preventing postoperative spinal deficits during posterior vertebral column resection (VCR) surgery for treatment of severe spine deformities, but the IOM features directing at VCR procedures are rarely reported and need to be further clarified. To evaluate an important surgical point that will lead to the IOM loss frequently, and then remind the surgeons to pay close attention to impending monitoring changes during posterior VCR surgery. Retrospective study. A total of 77 patients with severe spine deformities who underwent posterior VCR and deformity correction surgeries from January 2012 to May 2015 are retrospectively analyzed in our spine center. IOM (motor-evoked potentials [MEP] and somatosensory-evoked potentials) was used for intraoperative spinal function assessment. Patients were divided into 2 groups according to their preoperative spinal function, including 27 patients with preoperative spinal deficits and 50 patients with spinal normal. And the IOM data during surgery, especially among VCR procedures, were mainly analyzed in the present study. With the VCR procedure almost complete, most patients showed varying degrees of IOM loss that included 37 cases showing obvious IOM degenerations and 21 cases showing significant IOM loss with alerts immediately. Moreover, the patients with preoperative spinal deficits have more significant decreasing percentage in MEP amplitude (81% vs. 68%, p<.05) than those patients without. With the VCR procedure almost complete, surgeons must pay closely attention to the IOM signals and should be ready to take corresponding surgical measures to deal with the impeding monitoring loss.

    Type 2 diabetes mellitus (DM2) is a chronic disease caused by the underproduction of insulin in the organism and it is considered a risk factor to periodontal disease. This study performed a cross-sectional research on the main oral changes in patients with DM2 and nondiabetics, in Passo Fundo, Rio Grande do Sul, Brazil. The sample included 116 patients examined at the Diabetes Outpatient Clinic of the School of Medicine of the University of Passo Fundo (UPF) and 134 nondiabetic patients examined at the Examinations, Triage, and Emergency Sector of the School of Dentistry of UPF. Inclusion criteria for the study were patients over 35-years old, diagnosed with DM2 for more than 2 years. The same criteria were used for the control group, except for the presence of diabetes. Data collected were analyzed by Statistical Package for the Social Sciences 18.0 for Windows™ software and the Chi-square test at 5% significance. This study showed that, overall, oral lesions were more prevalent in diabetic patients. The stomatological manifestations observed more frequently in such patients were pseudomembranous candidia-sis, lichen planus, lingual varices, xerostomia, and prosthetic stomatitis (p > 0.001). Therefore, based on the sample investigated, it is concluded that patients with DM2 present higher prevalence of oral lesions when compared with nondiabetics. It is important for the dentist to know about oral lesions because they may allow either early diagnosis in patients unaware of this condition or help diagnosing a potential decompensation. Moreover, oral lesions may represent a potential gateway for infectious agents, and the dentist may restrain this condition by performing treatment as early as possible.

    Video-game playing is associated with an increased obesity risk. The association of video-game playing with body composition, physical activity and eating behaviour was investigated. A total of 45 young males (age range 18-27 years, BMI range 18.5-35.1 kg/m(2)) were recruited. Measurements of body composition and blood pressure were performed. The EPIC-FFQ questionnaire was used to assess dietary intake. A questionnaire battery was administered to assess physical activity, eating behaviour, sleep quality and frequency of video-game playing (hours/week). Subjects were categorised into frequent (>7 h/week) and non-frequent (≤7 h/week) players. Frequent video-game players had greater waist circumference and fat mass. Video-game playing was significantly associated with high added sugar and low fibre consumption. A higher level of dietary restraint was observed in non-frequent video-game users. These preliminary results identify frequent video-game playing as an important lifestyle behaviour which may have important implications for understanding obesity risk in young male adults.

    Full Text Available Five cases of neurospyhilis with atypical manifestation have been reported. Of these four cases presented as acute neurological illness and showed variable recovery after antisyp′iiilitic therapy. One of these cases had parinaud sip which was unaffected by treatment One case presented as dementia and gave poor response to therapy. In only one of these five cases was reagin in CSF demonstrated. Lange′s colloidal gold test was negative in all. As such failure to demonstrate reagin in CSF does not rule out the diagnosis of neurosyphilis. In an antibiotic era patients may inadvertently receive some antibiotics prior to presentation to a clinician and therefore are unlikely to present with typical neurological and laboratory findings.

The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

    In this study a multiple regression equation for prediction of ventilatory pulmonary function tests (FVC, FEV1%, FEF25-75% and PEFR) is developed in average healthy non-smoker male and female Gujarati subjects. The average adult female values showed a reduction varying from 21.0 to 29.0% compared to adult male subjects. There is a deviation of the present study values from other studies in Indian subjects and values from European studies are higher than the present values. This study demonstrated that the present regression equation is the most ideal and appropriate for prediction of pulmonary function values in Gujarati subjects either for assessing physical fitness in normal subjects or for determining the pattern of ventilatory impairment in respiratory disease patients. The pulmonary function values assessed by substituting the average age, height and weight of females in male regression equation revealed lower values in females ranging from 14.0 to 19.0% attributable only due to difference in sex.

    Esomeprazole 20 mg once daily has been shown to be effective for treating frequent heartburn over 14 days in subjects who are likely to self-treat with over-the-counter medications. These analyses were conducted to assess durability of effects and symptomatic rebound after cessation of treatment, treatment satisfaction, and rescue antacid use with esomeprazole 20 mg once daily for 14 days. Adults with frequent heartburn (≥ two days/week in the past four weeks) were randomly assigned to 14 days of double-blind treatment with esomeprazole 20 mg or placebo in two identical multicenter studies. All subjects entered a 1-week single-blind placebo follow-up period after treatment. The results of the primary efficacy endpoints were reported previously. The percentage of heartburn-free days during the 1-week follow-up, use of rescue antacids, and treatment satisfaction, measured with the Global Assessment Questions instrument, are described. The percentage of heartburn-free days was maintained during the 1-week follow-up period; the proportion was 43% among esomeprazole subjects in these studies, suggesting no evidence of symptomatic rebound. Rescue antacid use generally decreased compared with the run-in period in the 14-day treatment and 1-week follow-up periods. Significantly more subjects taking esomeprazole were "very satisfied" or "satisfied" with treatment versus placebo (Study 1: 78% vs. 63%, respectively, P = 0.0038; Study 2: 81% vs. 60%, respectively, P = 0.0002). Subjects who are likely to self-treat their frequent heartburn with over-the-counter medications reported satisfaction with esomeprazole 20 mg. Esomeprazole's treatment effect was maintained for ≥ one week after treatment ended, with no sign of symptomatic rebound. These trials were registered at ClinicalTrials.gov: NCT01370525; NCT01370538.

    BACKGROUND: Vitreous opacities and posterior vitreous detachment (PVD) disturb vision by degrading contrast sensitivity (AJO 172:7-12, 2016). Increased light scattering is the presumed mechanism. To test this hypothesis, dynamic light scattering (DLS) was performed on excised vitreous of patients with clinically significant floaters, and compared to macular pucker controls. METHODS: Undiluted, unfixed vitreous was procured during 25-gauge vitrectomy in 14 subjects (age = 59 +/- 6.6 years) with clinically significant vitreous floaters, and 6 controls (age = 66.5 +/- 8.7 years; P = 0.10) with macular pucker. Total protein concentration was determined by fluorescent Quant-iTTM protein assay kit (Invitrogen/Molecular Probes, Eugene, OR) with bovine serum albumin (0500 ng/ml) as a standard. Fluorescence (excitation at 470 nm and emission at 570 nm) was measured using a Gemini XPS Dual-Scanning Microplate Spectrofluorometer and data analyzed using SoftMax Pro software (Molecular Devices, Sunnyvale, CA). DLS (NS300, Malvern Instruments, Westborough, MA) measurements were performed in each specimen after 10-fold dilution in phosphate buffered saline to optimize concentration in each specimen and determine the mean number of particles, the particle size distributions, and the average particle sizes. RESULTS: Total protein concentration in vitreous specimens trended higher in macular pucker controls (1037 +/- 1038 μg/mL) than eyes with vitreous floaters (353.7 +/- 141.1 μg/mL P = 0.08). When normalized to total protein concentration, the number of particles in vitreous from floater eyes was more than 2-fold greater than controls (P vitreous from floater subjects as compared to controls (P vitreous from floater eyes was 315.8 +/- 194.6 nm, compared to 147.7 +/- 129.3 nm in macular pucker controls (P = 0.039). CONCLUSIONS: Vitreous from eyes with clinically significant floaters contains more particles of larger sizes as compared to controls, likely accounting for the

  2. The psychological present.

    Science.gov (United States)

    Hayes, L J

    1992-01-01

    The present paper compares behavior-analytic and cognitive treatments of the concept of psychological history with regard to its role in current action. Both treatments take the position that the past bears some responsibility for the present, and are thereby obligated to find a means of actualizing the past in the present. Both do so by arguing that the past is brought to bear in the present via the organism. Although the arguments of the two positions differ on this issue, neither provides a complete account. An unconventional treatment of psychological history is proposed, the logic of which is exemplified in anthropological, biological, and psychological perspectives. The unconventional treatment in psychological perspective holds that (a) the organism's interaction with its environment, not the organism itself, changes with experience; and (b) the past interactions of an organism exist as, and only as, the present interactions of that organism. This solution to the problem of psychological history provides obligations and opportunities for analysis that are not available when the more conventional positions of cognitivism and behavior analysis are adopted.

    Association rule mining research typically focuses on positive association rules (PARs), generated from frequently occurring itemsets. However, in recent years, there has been a significant research focused on finding interesting infrequent itemsets leading to the discovery of negative association rules (NARs). The discovery of infrequent itemsets is far more difficult than their counterparts, that is, frequent itemsets. These problems include infrequent itemsets discovery and generation of accurate NARs, and their huge number as compared with positive association rules. In medical science, for example, one is interested in factors which can either adjudicate the presence of a disease or write-off of its possibility. The vivid positive symptoms are often obvious; however, negative symptoms are subtler and more difficult to recognize and diagnose. In this paper, we propose an algorithm for discovering positive and negative association rules among frequent and infrequent itemsets. We identify associations among medications, symptoms, and laboratory results using state-of-the-art data mining technology.

Data originate from the national survey carried out in 2001 on health behavior of 15,379 adults aged 25-64. The overall response rate of the mailed questionnaire was 64%, with 9,043 questionnaires eligible for analysis. Binary multiple logistic regression was used to determine the impact of gender, age, education, employment, self-assessed social class, type of residence community, and geographical region on the prevalence of frequent stress perception. The highest odds for stress were registered in women (OR(women vs men)=1.39, Pgroup at very high risk for frequent stress perception with at least minor difficulties in coping with these feelings, requiring specific public health measures to be introduced in this group.

    Full Text Available Rhinoentomophthoromycosis caused by Conidiobolus sp commonly presents as a chronic granulomatous lesion that affects the rhinofacial subcutaneous tissue. We present an 18-year-old girl who presented with progressive bilateral proptosis and loss of vision since 2 weeks. Biopsy and fungal cultures confirmed diagnosis of Conidiobolus sp infection of the paranasal sinuses bilaterally with orbital extension and blindness. The clinical picture was complicated by the presence of sputum-positive cavitatory pulmonary tuberculosis, which was diagnosed at the same time. To our knowledge, this is the first such case to be reported from India. We also discuss the management of entomophthoromycosis. Despite many reports of success, there remains no consensus on the treatment of Conidiobolus infections of the nose and the paranasal sinuses with antifungal agents.

    The malignant cell in melanoma is the melanocyte. Because melanocytes are located in the basal layer of the epidermis, melanoma is most commonly seen on the skin. However, melanoma can also arise on mucosal surfaces such as the oral cavity, the upper gastrointestinal mucosa, the genital mucosa, as well as the uveal tract of the eye and leptomeninges. Melanomas tend to be pigmented but can also present as pink or red lesions. They can mimic benign or other malignant skin lesions. This chapter presents the spectrum of typical and less typical presentations of melanoma, as well as patterns of spread. It is divided into (1) cutaneous lesions; (2) patterns of regional spread, (3) non-cutaneous lesions; and (4) distant metastases.

    To establish the skeletal pattern in subjects with malocclusions and temporomandibular disorders (TMD); to assess the relationship between craniofacial skeletal structures and TMD in subjects with malocclusions. Sixty-four subjects with malocclusions, over 18 years of age, were included in the study. Temporomandibular disorders were clinically assessed according to the Helkimo Anamnestic Index. Subjects underwent a lateral cephalogram. Subjects were grouped according to the sagittal skeletal pattern (ANB angle) into class I, II and III. Parametric Student tests with equal or unequal variations were used (variations were previously tested with Levene test). Twenty-four patients with TMD (experimental sample); 40 patients without TMD (control group); interincisal angle was higher in class I and II (p < 0.05) experimental subjects; overjet was larger in experimental subjects; midline shift and Wits appraisal were broader in the experimental group in all three classes. In class III subjects, the SNB angle was higher in the experimental group (p = 0.01). Joint noises followed by reduced mandible mobility, muscular pain and temporomandibular joint (TMJ) pain were the most frequent symptoms in subjects with TMD and malocclusions. Temporomandibular joint status is an important factor to consider when planning orthodontic treatment in patients with severe malocclusions; midline shift, large overjet and deep overbite have been associated with signs and symptoms of TMD.

    Although milk/dairy consumption is part of many cultures and is recommended in most dietary guidelines around the world, its contribution to overall diet quality remains a matter of controversy, leading to a highly polarized debate within the scientific community, media and public sector. The present article, at first, describes the evolutionary roots of milk consumption, then reviews the milk-derived bioactive peptides as health-promoting components. The third part of the article, in general, presents the associations between milk nutrients, disease prevention, and health promotion.

    Hand dermatitis is a common diagnosis seen in dermatologic and general practice. It can present with typical morphology, but uncommon manifestations are possible. This review reports on common and uncommon presentations of irritant and allergic hand dermatitis focusing on uncommon localizations, time course, and morphology such as follicular, pustular, bullous, ulcerous, exudative erythema multiforme-like, purpuric, lichenoid, pigmented, and depigmented skin lesions. Clinical diagnosis can be challenging. Even histopathology is not always very helpful. Thorough evaluation of the patient's history and investigation of clinical morphology are the cornerstones of diagnosis.

    The article presents a notion of “analyzing in the present” as a source of inspiration in analyzing qualitative research materials. The term emerged from extensive listening to interview recordings during everyday commuting to university campus. Paying attention to the way different parts...... of various interviews conveyed diverse significance to the listening researcher at different times became a method of continuously opening up the empirical material in a reflexive, breakdown-oriented process of analysis. We argue that situating analysis in the present of analyzing emphasizes and acknowledges...

    Halitosis is a common condition, whose main etiology does not respond to diseases of the gastrointestinal system. Epiphrenic diverticula are a rare cause of this manifestation, thus they are not frequent and they are usually asymptomatic. However, they may produce symptoms with inability for patient. A patient with severe halitosis is presented. In his study, an epiphrenic diverticulum is diagnosed and the laparoscopic abdominal diverticulectomy is performed with a complete resolution of symptomatology.

    To evaluate the relationship between objectively measured memory functions and subjective complaints of memory disturbance and whether subjective complaints are affected by some personality traits or affective states. Cross-sectional two-group comparison. The city of Kuopio in Eastern Finland, considered representative of the urban elderly population of Finland. Originally 403 subjects aged 67-78 years from the random sample and then two matched study groups initially including eighteen subjects but only ten in the final analysis. Screening and follow-up examinations of subjects with and without subjective memory complaints: (1) Memory functions: Benton's visual retention test and the paired-associated learning subtest of Wechsler Memory Scale. (2) Memory complaints: Memory Complaint Questionnaire. (3) Personality traits and affective state: Two subscales from Minnesota Multiphasic Personality Inventory and Geriatric Depression Scale. Complaints of memory loss did not correlate with the actual memory performance in the tests. However, those subjects who most emphatically complained of memory disturbance had greater tendencies toward somatic complaining, higher feelings of anxiety about their physical health, and more negative feelings of their own competence and capabilities than those who did not complain of memory deterioration associated with aging. The study suggests that subjective feelings of memory impairment are more closely associated with personality traits than with actual memory performance in normal elderly people.

    In this work, I shall deal with the psychodynamic approach to subjectivity in P.V.C. To this effect, I want to develop the concept of subject and subjectivity, its variation and historical-social construction and its approach in counselling, from a psychodynamic conceptual framework in P.V.C. with a short reference to the theoretical sources on which this approach is founded.

  20. Gestalt perception and the decline of global precedence in older subjects.

    Our visual world is hierarchically organized. Hierarchical processing is frequently investigated using Navon figures (large letters made up of smaller ones). In young adults, many studies reported faster reaction times (RT) to target letters presented at the global level [i.e., global precedence (GP)]. Furthermore, an age-related decline of this GP has been reported. We tested whether deficits in perceptual grouping via Gestalt laws (Gestalt principles of Proximity and Continuity) might contribute to this decline. In a directed attention task with valid and invalid cues, 20 young (mean age 22) and 20 older (mean age 57) male subjects had to indicate whether a target letter appeared at the global or local level of a Navon figure. The number of local letters forming the global figure was modulated in 5 steps. As expected, during valid trials, young adults showed a GP that linearly increased with increasing numbers of local letters (i.e., GP enhancement). This suggests that GP is related to perceptual grouping via Gestalt laws. By contrast, the group of older subjects demonstrated no precedence effect in RT and a non-significant trend toward GP in error rates (ER). No GP enhancement with an increasing number of local elements was observed. Exploratory analysis revealed that individual insensitivity to the modulation of matrix density, as revealed by a lack of global RT acceleration, was restricted to subjects that showed an overall local precedence (LP). Because older subjects tended to more frequently display an insensitivity to matrix modulation and an LP, we conclude that deficient Gestalt detection as indicated by non-enhanced global RT might contribute to the RT-related decline of GP with age.
