Mining and analysis of audiology data to find significant factors associated with tinnitus masker

Objectives: The objective of this research is to find the factors associated with tinnitus masker from the literature, and by using the large amount of audiology data available from a large NHS (National Health Services, UK) hearing aid clinic. The factors evaluated were hearing impairment, age, gender, hearing aid type, mould and clinical comments. Design: The research includes literature survey for factors associated with tinnitus masker, and performs the analysis of audiology data using statistical and data mining techniques. Setting: This research uses a large audiology data but it also faced the problem of limited data for tinnitus. Participants: It uses 1,316 records for tinnitus and other diagnoses, and 10,437 records of clinical comments from a hearing aid clinic. Primary and secondary outcome measures: The research is looking for variables associated with tinnitus masker, and in future, these variables can be combined into a single model to develop a decision support system to predict about tinnitus masker for a patient. Results: The results demonstrated that tinnitus maskers are more likely to be fit to individuals with milder forms of hearing loss, and the factors age, gender, type of hearing aid and mould were all found significantly associated with tinnitus masker. In particular, those patients having Age<=55 years were more likely to wear a tinnitus masker, as well as those with milder forms of hearing loss. ITE (in the ear) hearing aids were also found associated with tinnitus masker. A feedback on the results of association of mould with tinnitus masker from a professional audiologist of a large NHS (National Health Services, UK) was also taken to better understand them. The results were obtained with different accuracy for different techniques. For example, the chi-squared test results were obtained with 95% accuracy, for Support and Confidence only those results were retained which had more than 1% Support and 80% Confidence. Conclusions: The variables audiograms, age, gender, hearing aid type and mould were found associated with the choice of tinnitus masker in the literature and by using statistical and data mining techniques. The further work in this research would lead to the development of a decision support system for tinnitus masker with an explanation that how that decision was obtained

New film-coated tablet formulation of deferasirox is well tolerated in patients with thalassemia or lower-risk MDS: Results of the randomized, phase II ECLIPSE study

Once-daily deferasirox dispersible tablets (DT) have a well-defined safety and efficacy profile and, compared with parenteral deferoxamine, provide greater patient adherence, satisfaction, and quality of life. However, barriers still exist to optimal adherence, including gastrointestinal tolerability and palatability, leading to development of a new film-coated tablet (FCT) formulation that can be swallowed with a light meal, without the need to disperse into a suspension prior to consumption. The randomized, open-label, phase II ECLIPSE study evaluated the safety of deferasirox DT and FCT formulations over 24 weeks in chelation-naïve or pre-treated patients aged ≥10 years, with transfusion-dependent thalassemia or IPSS-R very-low-, low-, or intermediate-risk myelodysplastic syndromes. One hundred seventy-three patients were randomized 1:1 to DT (n = 86) or FCT (n = 87). Adverse events (overall), consistent with the known deferasirox safety profile, were reported in similar proportions of patients for each formulation (DT 89.5%; FCT 89.7%), with a lower frequency of severe events observed in patients receiving FCT (19.5% vs. 25.6% DT). Laboratory parameters (serum creatinine, creatinine clearance, alanine aminotransferase, aspartate aminotransferase and urine protein/creatinine ratio) generally remained stable throughout the study. Patient-reported outcomes showed greater adherence and satisfaction, better palatability and fewer concerns with FCT than DT. Treatment compliance by pill count was higher with FCT (92.9%) than with DT (85.3%). This analysis suggests deferasirox FCT offers an improved formulation with enhanced patient satisfaction, which may improve adherence, thereby reducing frequency and severity of iron overload-related complications

Perceptions and concerns of healthy eating in low-income African American mothers of preschoolers

Health disparities are prevalent in the U.S, with low-income African American children suffering from higher rates of obesity and chronic diseases compared to White children. Currently, little is known about parental perceptions of healthy eating, and concerns related to child health and weight in this at-risk population. The main purpose of this study was to examine perceptions, motivating factors and barriers to healthier eating in a sample of low-income African American parents of 3-5 year old children. The second purpose was to assess parental concerns about health and/or weight and to examine the accuracy of parental perceptions of child weight status. Participants were recruited from Head Start Programs in North Carolina. The Social Cognitive Theory constructs guided focus groups and a survey administered to the participants. Content analysis of 8 focus groups generated the following themes: 1) lack of nutrition knowledge and misconceptions; 2) healthy meals are home-cooked, include meat and starch; 3) family members, lack of maternal modeling, and child pickiness are main barriers to healthier eating; 4) strong awareness of family history of chronic disease, including obesity; 5) lack of concern about child's current weight. Over 25% of mothers underestimated their child's weight status. Our findings highlight important maternal perspectives influencing children's diet quality and long-term health outcomes among low-income at-risk preschoolers. Nutrition educators should be aware that low-income African American mothers may be aware of chronic disease risks, but do not perceive food choices in early childhood as having strong impact on the child's future health

An interpretative essay concerning twelve paintings

The purpose of this essay is to interpret the author's thesis paintings which, exist as a manifestation of his reality from reality. The objective has been to carry each observer into his own soul in order to conjure a realm of existence in which one may stretch each sense to its point of transcendence. Here, where the absence of reason is the fuel for flight, the only means of mental conveyance to the sublime, human knowledge and experience cease; and one is able to realize his God-reflected self and grasp a bit of the infinite. There is a mood which captivates and frees the human mind from the directness of reality—and seems as important. Given complete freedom, it is capable of becoming reality; controlled, it refreshes and relaxes. This mood is fantasy—the fantasy found in a Perrault fairy tale, where no moral is sought or lesson prescribed. It is the recognition of a naive freshness embodied in the imagination of a child, apparently free from the sophisticated conflicts within adults

Development of a self-instructional program on the sewing machine

Modern science and technology have resulted in a tremendous increase in knowledge which has made it difficult for students and teachers to keep up with changes. These changes make education more essential to our progress. Students find themselves in overcrowded classrooms and teachers find themselves trying to meet the needs of each individual student. Such dilemma results in frustration for both. Steps have been taken to improve these conditions. Psychologists have advanced during the last decade a revolutionary new method of teaching and learning which may help to solve the problems of the increase in knowledge and overcrowding in the classroom. This method is popularly called automated or programed instruction. Briefly programed instruction takes the place of a tutor as it leads the student through a set of materials designed and sequenced to teach him to behave in a certain way

Impaired decisional impulsivity in pathological videogamers

Abstract Background Pathological gaming is an emerging and poorly understood problem. Impulsivity is commonly impaired in disorders of behavioural and substance addiction, hence we sought to systematically investigate the different subtypes of decisional and motor impulsivity in a well-defined pathological gaming cohort. Methods Fifty-two pathological gaming subjects and age-, gender- and IQ-matched healthy volunteers were tested on decisional impulsivity (Information Sampling Task testing reflection impulsivity and delay discounting questionnaire testing impulsive choice), and motor impulsivity (Stop Signal Task testing motor response inhibition, and the premature responding task). We used stringent diagnostic criteria highlighting functional impairment. Results In the Information Sampling Task, pathological gaming participants sampled less evidence prior to making a decision and scored fewer points compared with healthy volunteers. Gaming severity was also negatively correlated with evidence gathered and positively correlated with sampling error and points acquired. In the delay discounting task, pathological gamers made more impulsive choices, preferring smaller immediate over larger delayed rewards. Pathological gamers made more premature responses related to comorbid nicotine use. Greater number of hours played also correlated with a Motivational Index. Greater frequency of role playing games was associated with impaired motor response inhibition and strategy games with faster Go reaction time. Conclusions We show that pathological gaming is associated with impaired decisional impulsivity with negative consequences in task performance. Decisional impulsivity may be a potential target in therapeutic management

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final version published in European Physical Journal
