Group normalization for genomic data.
Ghandi, Mahmoud; Beer, Michael A
2012-01-01
Data normalization is a crucial preliminary step in analyzing genomic datasets. The goal of normalization is to remove global variation to make readings across different experiments comparable. In addition, most genomic loci have non-uniform sensitivity to any given assay because of variation in local sequence properties. In microarray experiments, this non-uniform sensitivity is due to different DNA hybridization and cross-hybridization efficiencies, known as the probe effect. In this paper we introduce a new scheme, called Group Normalization (GN), to remove both global and local biases in one integrated step, whereby we determine the normalized probe signal by finding a set of reference probes with similar responses. Compared to conventional normalization methods such as Quantile normalization and physically motivated probe effect models, our proposed method is general in the sense that it does not require the assumption that the underlying signal distribution be identical for the treatment and control, and is flexible enough to correct for nonlinear and higher order probe effects. The Group Normalization algorithm is computationally efficient and easy to implement. We also describe a variant of the Group Normalization algorithm, called Cross Normalization, which efficiently amplifies biologically relevant differences between any two genomic datasets.

The restricted holonomy group of a Riemannian manifold is a compact Lie group and its representation on the tangent space is a product of irreducible representations and a trivial one. Each one of the non-trivial factors is either an orthogonal representation of a connected compact Lie group which acts transitively on the unit sphere or it is the isotropy representation of a single Riemannian symmetric space of rank ≥ 2. We prove that, all these properties are also true for the representation on the normal space of the restricted normal holonomy group of any submanifold of a space of constant curvature. 4 refs

In this study, ketogenic diet-induced biochemical changes occurring in normal and epileptic hippocampal formations were compared. Four groups of rats were analyzed, namely seizure experiencing animals and normal rats previously fed with ketogenic (KSE and K groups respectively) or standard laboratory diet (NSE and N groups respectively). Synchrotron radiation based Fourier-transform infrared microspectroscopy was used for the analysis of distributions of the main organic components (proteins, lipids, compounds containing phosphate group(s)) and their structural modifications as well as anomalies in creatine accumulation with micrometer spatial resolution. Infrared spectra recorded in the molecular layers of the dentate gyrus (DG) areas of normal rats on a ketogenic diet (K) presented increased intensity of the 1740 cm(-1) absorption band. This originates from the stretching vibrations of carbonyl groups and probably reflects increased accumulation of ketone bodies occurring in animals on a high fat diet compared to those fed with a standard laboratory diet (N). The comparison of K and N groups showed, moreover, elevated ratios of absorbance at 1634 and 1658 cm(-1) for DG internal layers and increased accumulation of creatine deposits in sector 3 of the Ammon's horn (CA3) hippocampal area of ketogenic diet fed rats. In multiform and internal layers of CA3, seizure experiencing animals on ketogenic diet (KSE) presented a lower ratio of absorbance at 1634 and 1658 cm(-1) compared to rats on standard laboratory diet (NSE). Moreover, in some of the examined cellular layers, the increased intensity of the 2924 cm(-1) lipid band as well as the massifs of 2800-3000 cm(-1) and 1360-1480 cm(-1), was found in KSE compared to NSE animals. The intensity of the 1740 cm(-1) band was diminished in DG molecular layers of KSE rats. The ketogenic diet did not modify the seizure induced anomalies in the unsaturation level of lipids or the number of creatine deposits.

Who helps the leaders? Difficulties experienced by cancer support group leaders.
Kirsten, Laura; Butow, Phyllis; Price, Melanie; Hobbs, Kim; Sunquist, Kendra
2006-07-01
Cancer support groups are an important source of support for cancer patients, yet little is known about the challenges and training needs of both professionally trained and untrained leaders. The aim of this study was to discover the difficulties experienced and training desired by cancer support group leaders. Twenty-seven leaders of 34 cancer support groups participated in focus groups or individual interviews. Groups were purposively selected as representative of 173 support groups identified in New South Wales which were for adults with cancer and/or their adult carers and were not therapeutic or education-only groups. Difficulties identified included dealing with people's different communication styles and needs; dealing with recurrence, metastases and death; practical issues, including resources, setting the programme and funding security; maintaining personal balance and preventing burn out; establishing group credibility; dealing with group cycles; and leading groups in rural areas. Leaders also identified benefits and rewards from group leadership such as contributing to others' well-being, self-development and insight into others' lives. Non-professionally trained leaders experienced more difficulties, particularly in dealing with group process and practical issues. Difficulties identified were related both to working with a cancer population specifically and to working with groups in general. While some issues were common to both health professionals and non-health professionals, non-health professionals reported greater supportive needs. Clear guidelines, targeted training and development of better methods of support to reduce the stress and burn out experienced by group leaders are needed.

10 experienced Shotokan karateka were tested on performance time and distance from a marker on the five Heian kata under normal sighted and blind-folded conditions. Whilst each kata's line of movement is different, it is the intention to start and finish at the same location. Analysis showed that despite an average of 16.8 yr. of training, whilst timing was not significantly affected on four of the kata by subjects being deprived of the visual sense, the group's mean change in distance from an original marker was significant for performances on three of the kata.

The Bobath concept, usually known as neuro-developmental treatment (NDT) in America, is one of the major approaches used to rehabilitate patients following stroke; however since the last publication of Bobath (1990), the concept has been taught via an oral tradition on postgraduate courses. This study therefore aimed to explore with experienced therapists firstly how the Bobath concept had changed since 1990, and secondly what they considered its main theoretical assumptions to be using a focus group research design. Eight peer-nominated expert physiotherapists agreed to participate in two focus groups organized according to specialist interest in either neurology (group A) or elderly care (group B). Therapists were asked to discuss six topics based on a review of published literature. Data analysis involved several readings of verbatim transcriptions, from which key themes and concepts were developed. All therapists agreed on the following core themes defining Bobath: analysis of normal movement, control of tone and facilitation of movement. Neuroplasticity was described as the primary rationale for treatment with therapists using afferent information to target the damaged central nervous system. In addition group A discussed motor learning, whereas group B discussed patient focused goals and relating treatment to function. This study highlighted changes in theory, terminology, and techniques. Tone remained a major problem in the rehabilitation management of the hemiplegic patient; however much attention was also directed towards the musculoskeletal system. Both facilitation of normal movement components and task specific practice using specific manual guidance were considered critical elements of the Bobath concept. For Bobath therapists, physiotherapy has an important impact on both the performance components of movement and functional outcomes. In view of the small numbers involved in this preliminary study, further studies are now needed to determine if these

About normal distribution on SO(3) group in texture analysis
Savyolova, T. I.; Filatov, S. V.
2017-12-01
This article studies and compares different normal distributions (NDs) on SO(3) group, which are used in texture analysis. Those NDs are: Fisher normal distribution (FND), Bunge normal distribution (BND), central normal distribution (CND) and wrapped normal distribution (WND). All of the previously mentioned NDs are central functions on SO(3) group. CND is a subcase for normal CLT-motivated distributions on SO(3) (CLT here is Parthasarathy’s central limit theorem). WND is motivated by CLT in R 3 and mapped to SO(3) group. A Monte Carlo method for modeling normally distributed values was studied for both CND and WND. All of the NDs mentioned above are used for modeling different components of crystallites orientation distribution function in texture analysis.

BACKGROUND: Global mean (GM) normalization is one of the most commonly used methods of normalization in PET and SPECT group comparison studies of neurodegenerative disorders. It requires that no between-group GM difference is present, which may be strongly violated in neurodegenerative disorders....... Importantly, such GM differences often elude detection due to the large intrinsic variance in absolute values of cerebral blood flow or glucose consumption. Alternative methods of normalization are needed for this type of data. MATERIALS AND METHODS: Two types of simulation were performed using CBF images...

Human-experienced temperature changes exceed global average climate changes for all income groups
Hsiang, S. M.; Parshall, L.
2009-12-01
Global climate change alters local climates everywhere. Many climate change impacts, such as those affecting health, agriculture and labor productivity, depend on these local climatic changes, not global mean change. Traditional, spatially averaged climate change estimates are strongly influenced by the response of icecaps and oceans, providing limited information on human-experienced climatic changes. If used improperly by decision-makers, these estimates distort estimated costs of climate change. We overlay the IPCC’s 20 GCM simulations on the global population distribution to estimate local climatic changes experienced by the world population in the 21st century. The A1B scenario leads to a well-known rise in global average surface temperature of +2.0°C between the periods 2011-2030 and 2080-2099. Projected on the global population distribution in 2000, the median human will experience an annual average rise of +2.3°C (4.1°F) and the average human will experience a rise of +2.4°C (4.3°F). Less than 1% of the population will experience changes smaller than +1.0°C (1.8°F), while 25% and 10% of the population will experience changes greater than +2.9°C (5.2°F) and +3.5°C (6.2°F) respectively. 67% of the world population experiences temperature changes greater than the area-weighted average change of +2.0°C (3.6°F). Using two approaches to characterize the spatial distribution of income, we show that the wealthiest, middle and poorest thirds of the global population experience similar changes, with no group dominating the global average. Calculations for precipitation indicate that there is little change in average precipitation, but redistributions of precipitation occur in all income groups. These results suggest that economists and policy-makers using spatially averaged estimates of climate change to approximate local changes will systematically and significantly underestimate the impacts of climate change on the 21st century population.

Sadness induced by music listening has been a popular research focus in music and emotion research. Despite the wide consensus in affective sciences that emotional experiences are social processes, previous studies have only concentrated on individuals. Thus, the intersubjective dimension of musical experience – how music and music-related emotions are experienced between individuals – has not been investigated. In order to tap into shared emotional experiences, group discussions about experi...

The paper investigates the relationship between perceived social support in the workplace and both negative (post-traumatic stress disorder (PTSD) symptoms) and positive outcomes (post-traumatic growth) of experienced traumatic events in a group of male emergency service workers. Data of 116 workers representing emergency services (37.1% firefighters, 37.1%, police officers and 30% medical rescue workers) who have experienced a traumatic event in their worksite were analyzed. The range of age of the participants was 21-57 years (M=35.27; SD=8.13). Polish versions of the Impact of Event Scale--Revised and the Post-traumatic Growth Inventory were used to assess the negative and positive outcomes of the experienced event. A perceived social support scale was measured by the scale What support you can count on. The data obtained from the study revealed the negative dependence of social support from supervisors with PTSD symptoms and positive--social support from co-workers with post-traumatic growth. Moreover the results of the study indicate the positive relationship between negative and positive outcomes of experienced traumatic events in the workplace. Perceived social support plays a more important role in gaining benefits from trauma than preventing negative outcomes of the experienced traumatic event. Support from co-workers, compared to support from supervisors, has greater importance.

A group of facial normal descriptors for recognizing 3D identical twins
Li, Huibin
2012-09-01
In this paper, to characterize and distinguish identical twins, three popular texture descriptors: i.e. local binary patterns (LBPs), gabor filters (GFs) and local gabor binary patterns (LGBPs) are employed to encode the normal components (x, y and z) of the 3D facial surfaces of identical twins respectively. A group of facial normal descriptors are thus achieved, including Normal Local Binary Patterns descriptor (N-LBPs), Normal Gabor Filters descriptor (N-GFs) and Normal Local Gabor Binary Patterns descriptor (N-LGBPs). All these normal encoding based descriptors are further fed into sparse representation classifier (SRC) for identification. Experimental results on the 3D TEC database demonstrate that these proposed normal encoding based descriptors are very discriminative and efficient, achieving comparable performance to the best of state-of-the-art algorithms. © 2012 IEEE.

The purpose of this report is to determine the normal value of the ventricular size on CT, snd analyze its changes with age in normal pediatric group. Materials and Methods: We searched through our 240 normal pediatric CT film files, aged 4 months to 14 years. Scans were performed on Hitachi CT-II scanner, using 10 mm collimation. Results: 1. The width of the third ventricle showed the same value in all pediatric groups, the mean value of its being 4.8 mm (SD 1.3 mm). 2. Bicaudate cerebroventricular indexes of the anterior horns of lateral ventricles (interecarlate distance/transverse diameter of the brain x100) were 15.3 in infants under one year, 13.8 in the age of one year and 12.7 in the children over two years. The indexes were almost the same in old age group over the age of three years. 3. The upper limit of the normal inverse cella media index (minium width of cella media/transverse diameter of the brain x100) was 31. Therefore the cases with the index above this range can be diagnosed as hydrocephalic. 4. The shape of the anterior horns of lateral ventricles was Y-shaped in infants under one year. II-shaped (paralied shaped) in the age of 1 - 12 years, and again it was Y-shaped in the group over 12 years. 5. In the age group under one year, the temporal horns of the lateral ventricles were visualized in about 60% cases, while the figure decreased to 20% in the older group. (author)

A radioimmunoassay (RIA) for human group I pepsinogens (PgI) in serum was developed, using PgI purified from gastric mucosa. The sensitivity (0.7 μg/l) and reproducibility of the assay were satisfactory for clinical use. In normal controls total serum pepsinogen (T-Pg) level was 58.9 +- 31.7 μg/l (mean +- SD) (PgI, 43.6 +- 25.0 μg/l; PgII, 15.3 +- 11.1 μg/l). Peptic ulcer cases had elevated T-Pg levels (gastric ulcer, gastroduodenal ulcer and duodenal ulcer, in increasing order of magnitude). T-Pg levels were not useful for diagnosis of peptic ulcer because of a large overlap with normal controls. T-Pg levels were low in patients with gastric polyp and in aged subjects. In these groups, the decrease of PgI was more marked than that of PgII. (Auth.)

Therefore, this study aimed to compare executive function and behavioral inhibition within patients suffering from schizophrenia, bipolar type I as well as a normal group. Methods: In this descriptive-comparative study, out of all patients hospitalized in daily psychiatric clinic in Najafabad in 2014 due to these disorders, 20 schizophrenia and 20 bipolar type I as well as 20 normal individuals were selected via the convinience sampling. All the study participants completed the computerizing tests including Tower of London and Go-No Go. The study data were analyzed utilizing SPSS software (ver 22 via MANOVA. Results: The study findings revealed a significant difference between the two patient groups and the normal group in regard with executive function and behavioral inhibition (p<0.05, whereas no differences were detected between schizophrenics and bipolar patient groups. Furthermore, patients suffering from schizophrenia and bipolar I mood disorder demonstrated significantly poor performance in cognitive function and behavioral inhibition compared to the normal group. Conclusion: The present study results can be significantly applied in pathology and therapy of these disorders, so as recognizing the inability of such patients can be effective in developing cognitive rehabilitation programs in these patients.

Obese and Overweight Youth: Risk for Experiencing Bullying Victimization and Internalizing Symptoms.
Waasdorp, Tracy Evian; Mehari, Krista; Bradshaw, Catherine P
2018-01-22
Obese and overweight youth are at an increased risk for poor peer relations and psychosocial adjustment. Of particular concern is the high rate of bullying victimization experienced by obese and overweight youth. While it is known that victimized youth are at an increased risk for internalizing symptoms, few studies have examined if weight status exacerbates the association between victimization and internalizing symptoms. The current study drew upon data from over 43,000 youth attending 107 middle and high schools. Multilevel results suggested that compared with normal weight youth, both overweight and obese youth were at an increased risk for experiencing relational, verbal, and cyber victimization, with only obese youth being at an increased risk for experiencing physical victimization. Notably, the odds for experiencing cyber victimization were higher than the odds for experiencing other forms of victimization. Frequently victimized obese youth, but not frequently victimized overweight youth, had significantly higher levels of internalizing symptoms compared to their frequently victimized, normal-weight peers. Together, these findings highlight the increased risk for psychosocial adjustment problems among frequently victimized overweight and obese youth, suggesting these youth may require preventive interventions tailored to meet their unique needs.

Normalization of feature vector values is a common practice in machine learning. Generally, each feature value is standardized to the unit hypercube or by normalizing to zero mean and unit variance. Classification decisions based on support vector machines (SVMs) or by other methods are sensitive to the specific normalization used on the features. In the context of multivariate pattern analysis using neuroimaging data, standardization effectively up- and down-weights features based on their individual variability. Since the standard approach uses the entire data set to guide the normalization, it utilizes the total variability of these features. This total variation is inevitably dependent on the amount of marginal separation between groups. Thus, such a normalization may attenuate the separability of the data in high dimensional space. In this work we propose an alternate approach that uses an estimate of the control-group standard deviation to normalize features before training. We study our proposed approach in the context of group classification using structural MRI data. We show that control-based normalization leads to better reproducibility of estimated multivariate disease patterns and improves the classifier performance in many cases.

The specific position of a group in the molecule has been considered, and a group vector space method for estimating enthalpy of vaporization at the normal boiling point of organic compounds has been developed. Expression for enthalpy of vaporization Delta(vap)H(T(b)) has been established and numerical values of relative group parameters obtained. The average percent deviation of estimation of Delta(vap)H(T(b)) is 1.16, which show that the present method demonstrates significant improvement in applicability to predict the enthalpy of vaporization at the normal boiling point, compared the conventional group methods.

Purpose: To define a male and female pelvic normal tissue contouring atlas for Radiation Therapy Oncology Group (RTOG) trials. Methods and Materials: One male pelvis computed tomography (CT) data set and one female pelvis CT data set were shared via the Image-Guided Therapy QA Center. A total of 16 radiation oncologists participated. The following organs at risk were contoured in both CT sets: anus, anorectum, rectum (gastrointestinal and genitourinary definitions), bowel NOS (not otherwise specified), small bowel, large bowel, and proximal femurs. The following were contoured in the male set only: bladder, prostate, seminal vesicles, and penile bulb. The following were contoured in the female set only: uterus, cervix, and ovaries. A computer program used the binomial distribution to generate 95% group consensus contours. These contours and definitions were then reviewed by the group and modified. Results: The panel achieved consensus definitions for pelvic normal tissue contouring in RTOG trials with these standardized names: Rectum, AnoRectum, SmallBowel, Colon, BowelBag, Bladder, UteroCervix, Adnexa{sub R}, Adnexa{sub L}, Prostate, SeminalVesc, PenileBulb, Femur{sub R}, and Femur{sub L}. Two additional normal structures whose purpose is to serve as targets in anal and rectal cancer were defined: AnoRectumSig and Mesorectum. Detailed target volume contouring guidelines and images are discussed. Conclusions: Consensus guidelines for pelvic normal tissue contouring were reached and are available as a CT image atlas on the RTOG Web site. This will allow uniformity in defining normal tissues for clinical trials delivering pelvic radiation and will facilitate future normal tissue complication research.

The advance selling strategy is implemented when a firm offers consumers the opportunity to order its product in advance of the regular selling season. Advance selling reduces uncertainty for both the firm and the buyer and enables the firm to update its forecast of future demand. The distinctive feature of the present theoretical study of advance selling is that we divide consumers into two groups, experienced and inexperienced. Experienced consumers know their valuations of the product in a...

Physical characteristics of experienced and junior open-wheel car drivers.
Raschner, Christian; Platzer, Hans-Peter; Patterson, Carson
2013-01-01
Despite the popularity of open-wheel car racing, scientific literature about the physical characteristics of competitive race car drivers is scarce. The purpose of this study was to compare selected fitness parameters of experienced and junior open-wheel race car drivers. The experienced drivers consisted of five Formula One, two GP2 and two Formula 3 drivers, and the nine junior drivers drove in the Formula Master, Koenig, BMW and Renault series. The following fitness parameters were tested: multiple reactions, multiple anticipation, postural stability, isometric upper body strength, isometric leg extension strength, isometric grip strength, cyclic foot speed and jump height. The group differences were calculated using the Mann-Whitney U-test. Because of the multiple testing strategy used, the statistical significance was Bonferroni corrected and set at P < 0.004. Significant differences between the experienced and junior drivers were found only for the jump height parameter (P = 0.002). The experienced drivers tended to perform better in leg strength (P = 0.009), cyclic foot speed (P = 0.024) and grip strength (P = 0.058). None of the other variables differed between the groups. The results suggested that the experienced drivers were significantly more powerful than the junior drivers: they tended to be quicker and stronger (18% to 25%) but without statistical significance. The experienced drivers demonstrated excellent strength and power compared with other high-performance athletes.

Fifteen years after parental divorce: mental health and experienced life-events.
Angarne-Lindberg, Teresia; Wadsby, Marie
2009-01-01
The children who experienced their parents' divorce when the divorce rate in Sweden had begun to grow to higher levels than in preceding decades are today adults. The aim of this study was to investigate if adults who had experienced parental divorce 15 years before the time of our study, differed in mental health from those with continuously married parents, taking into account life events other than the divorce. Instruments used were the Symptom Checklist (SCL-90) measuring mental health and the Life Event questionnaire capturing the number and experience of occurred events. Forty-eight persons, who were 7-18 years old when their parents divorced, constituted the divorce group, and 48 persons matched on age, sex and growth environment formed the study groups. The SCL-90 showed a limited difference between the groups, but not concerning total mental health. A main finding was a difference with regard to sex and age; women aged 22-27 in the divorce group displayed poorer mental health than other participants in both groups. The results from the Life Event questionnaire showed that the divorce group had experienced a significantly larger number of events, and more life events were described as negative with difficult adjustment. A regression analysis showed a significant relation between the SCL-90, Global Severity Index and life events experienced as negative with difficult adjustment, divorce events excluded, but not with the divorce itself. It seems highly desirable to pay more attention than has thus far been paid to girls with experience of childhood divorce at age 7-12.

Stigma is a major social barrier that can restrict access to and willingness to seek psychiatric care. Psychiatric consumers may use secrecy and withdrawal in an attempt to cope with stigma. The purpose of this study was to determine the effects of music therapy on self- and experienced stigma in acute care psychiatric inpatients using a randomized design with wait-list control. Participants (N=83) were randomly assigned by cluster to one of three single-session group-based conditions: music therapy, education, or wait-list control. Participants in the music therapy and education conditions completed only posttests while participants in the wait-list control condition completed only pretests. The music therapy condition was a group songwriting intervention wherein participants composed lyrics for "the stigma blues." Results indicated significant differences in measures of discrimination (experienced stigma), disclosure (self-stigma), and total stigma between participants in the music therapy condition and participants in the wait-list control condition. From the results of this randomized controlled investigation, music therapy may be an engaging and effective psychosocial technique to treat stigma. Limitations, suggestions for future research, and implications for clinical practice and psychiatric music therapy research are provided. © 2013.

Effect of non-normality on test statistics for one-way independent groups designs.
Cribbie, Robert A; Fiksenbaum, Lisa; Keselman, H J; Wilcox, Rand R
2012-02-01
The data obtained from one-way independent groups designs is typically non-normal in form and rarely equally variable across treatment populations (i.e., population variances are heterogeneous). Consequently, the classical test statistic that is used to assess statistical significance (i.e., the analysis of variance F test) typically provides invalid results (e.g., too many Type I errors, reduced power). For this reason, there has been considerable interest in finding a test statistic that is appropriate under conditions of non-normality and variance heterogeneity. Previously recommended procedures for analysing such data include the James test, the Welch test applied either to the usual least squares estimators of central tendency and variability, or the Welch test with robust estimators (i.e., trimmed means and Winsorized variances). A new statistic proposed by Krishnamoorthy, Lu, and Mathew, intended to deal with heterogeneous variances, though not non-normality, uses a parametric bootstrap procedure. In their investigation of the parametric bootstrap test, the authors examined its operating characteristics under limited conditions and did not compare it to the Welch test based on robust estimators. Thus, we investigated how the parametric bootstrap procedure and a modified parametric bootstrap procedure based on trimmed means perform relative to previously recommended procedures when data are non-normal and heterogeneous. The results indicated that the tests based on trimmed means offer the best Type I error control and power when variances are unequal and at least some of the distribution shapes are non-normal. © 2011 The British Psychological Society.

Purpose To compare the diagnostic performance of glaucoma specialists and experienced optometrists in gonioscopy and optic disc assessment. Methods This study was done to validate the diagnostic performance of two experienced optometrists for using their skills of detecting glaucoma using gonioscopy and optic disc assessment in a major epidemiological study, the L V Prasad Eye Institute Glaucoma Epidemiology and Molecular Genetics Study (LVPEI-GLEAMS). Gonioscopic findings for 150 eyes were categorized as 0, 1 and 2 for open angle, primary angle closure suspect (PACS) and primary angle closure (PAC) respectively. Optic disc findings for 200 eyes were categorized as 0, 1 and 2 for normal, suspects and glaucomatous respectively. Weighted kappa (κ) and diagnostic accuracy parameters were calculated. Two optometrists (#1 and #2) participated in the study. Results Agreement between glaucoma specialists and optometrist for interpretation of gonioscopy to discriminate PACS and PAC from open angles and for interpretation of optic disc to discriminate glaucomatous and suspicious discs from normal, the kappa (κ) was 0.92 and 0.84 and 0.90 and 0.89 for optometrists #1 and #2 respectively. Sensitivities and specificities were above 90% for gonioscopy. Optic disc evaluation had specificities greater than 95% to discriminate normal from glaucomatous discs while the sensitivities were 83% and 93% for optometrists #1 and #2 respectively. Conclusion Agreement between optometrists and glaucoma specialists, in diagnostic performance of gonioscopy and optic assessment was excellent with high sensitivity and specificity. Hence, we conclude that the experienced optometrists can detect glaucoma accurately in the LVPEI-GLEAMS.

Full Text Available Background and Aim: While most of the people with tinnitus have some degrees of hearing impairment, a small percent of patients admitted to ear, nose and throat clinics or hearing evaluation centers are those who complain of tinnitus despite having normal hearing thresholds. This study was performed to better understanding of the reasons of probable causes of tinnitus and to investigate possible changes in the auditory brainstem function in normal-hearing patients with chronic tinnitus.Methods: In this comparative cross-sectional, descriptive and analytic study, 52 ears (26 with and 26 without tinnitus were examined. Components of the auditory brainstem response (ABR including wave latencies and wave amplitudes were determined in the two groups and analyzed using appropriate statistical methods.Results: The mean differences between the absolute latencies of waves I, III and V was less than 0.1 ms between the two groups that was not statistically significant. Also, the interpeak latency values of waves I-III, III-V and I-V in both groups had no significant difference. Only, the V/I amplitude ratio in the tinnitus group was significantly higher (p=0.04.Conclusion: The changes observed in amplitude of waves, especially in the latter ones, can be considered as an indication of plastic changes in neuronal activity and its possible role in generation of tinnitus in normal-hearing patients.

The aim of this study was to investigate the impact of caregiver knowledge and experience on muscle activity and perceived exertion while repositioning bedridden patients. Subjects were 40- to 65-year-old female caregivers divided into novice and experienced groups. Subjects from both groups performed home-care repositioning techniques on bedridden patients while muscle activity was recorded via electromyogram. Recordings were made from four muscles on the subjects' dominant side: the latissimus dorsi, the biceps brachii, the erector spinae, and the rectus femoris. The subjective burden involved in repositioning was also assessed using the rate of perceived exertion (RPE) and visual analog scales (VAS). Rectus femoris percentage of maximum voluntary contraction (%MVC) values were significantly lower than latissimus dorsi, erector spinae, and biceps brachii values in the novice group. %MVC values from the latissimus dorsi and biceps brachii were significantly higher among the novice group compared to the experienced group. RPE ratings from the novice group were significantly higher than those of the experienced group, and there was a non-significant trend for higher VAS values for the low back, arms, and legs in the novice group compared to the experienced group. Novice caregivers tended to change the patient's position by pulling with the upper limbs without using the lower limbs. In contrast, experienced caregivers exerted less energy by communicating with the patient and utilizing the patient's own movements. They used large, distributed muscle groups that effectively harnessed body mechanics and prevented excess exertion.

Communal normalization in an online self-help group for adolescents with a mentally ill parent.
Trondsen, Marianne V; Tjora, Aksel
2014-10-01
Although implications of parental mental illness are well documented, most children of mentally ill parents are left to manage their family situation with limited information and support. We explored the role of a Norwegian online self-help group for adolescents (aged 15 to 18) with a mentally ill parent. Through in-depth interviews with 13 participants, we found that the online self-help group provided "communal normalization" by which participants, through communication in the forum, made sense of everyday experiences and emotions arising from having a mentally ill parent. We identified three main aspects of this process-recognizability, openness, and agency-all of which were important for the adolescents' efforts to obtain support, to be supportive, and to handle everyday life situations better. Communal normalization might provide resources for significantly improving the participants' life situations, and could demonstrate similar potential for users in other situations characterized by stigma, loneliness, silence, and health worries. © The Author(s) 2014.

Full Text Available Burnout is a serious psychological syndrome that can affect not only an individual’s well-being, but also the functioning of whole organisations, such as schools. It is characterized by emotional exhaustion, depersonalization, and decreased personal accomplishment.The level of burnout among teachers in the field of education has a negative impact on student success. The present investigation examines the level of burn out among high and low experienced teachers. It focused on a group of English teachers from different nationalities: Iranian, and Malaysian at UPM to examine if there is any relation between burnout and experience level. The sample consisted of 30 English teachers. Two instruments namely, The Maslach Burnout Inventory and Demographic Questionnaire were used to collect data. Data analysis revealed that there is no significant difference in depersonalization and personal accomplishment scores between low and high experienced teachers. But the result of this study also revealed that there is a significant difference in Emotional Exhaustion scores between low and high experienced teachers. Further research is required to explore the roots and the causes of burnout.

Gordon, Danny; Pratama, Mario Prajna
2017-01-01
This work sought to document how Indonesian trans* FtM persons experienced discrimination across the interlinked domains of social networks, religious and educational institutions, employment and the workplace, and health care institutions. Objectives were (1) to map the discrimination experienced by trans* FtM individuals in Indonesia, and (2) to establish the specific priorities of the Indonesian trans* FtM community. In-depth interviews, focus groups, and participant observation was used involving 14 respondents. Findings revealed that respondents experienced othering through rejection, misidentification, harassment, "correction," and bureaucratic discrimination across the five preestablished domains. Health care and a lack of information emerged as areas of particular concern for respondents. This work calls for health care that is sensitive to the needs of trans* FtM people coupled with high-quality information to alleviate the cycles through which discrimination is sustained.

Quantitative thallium-201 myocardial exercise scintigraphy was tested in two patient populations representing alternative standards for cardiac normality: group I comprised 18 male uncatherized patients with a low likelihood of coronary artery disease (CAD); group II contained 41 patients with normal coronary arteriograms. Group I patients were younger, they achieved a higher rate-pressure product than group II patients; all had normal findings by phisical examination and electrocardiography at rest and exercise. Group II patients comprised 21 females, 11 patients showed abnormal electrocardiography at rest, and five patients showed ischemic ST depression during exercise. Twelve patients had sign of minimal CAD. Twelve patients revealed abnormal visual and quantitative thallium findings, three of these patients had minimal CAD. Profiles of uptake and washout of thallium-201 were derived from both patient groups, and compared with normal limits developed by Maddahi et al. Furthermore, low likelihood and angiographically normal patients may differ substantially, and both sets of normal patients should be considered when establishing criteria of abnormality in exercise thallium imaging. When commercial software containing normal limits for quantitative analysis of exercise thallium-201 imaging is used in clinical practice, it is mandatory to compare these with normal limits of uptake and washout of thallium-201, derived from the less heterogeneous group of low-likelihood subjects, which should be used in selecting a normal population to define normality.

Nystagmus responses in a group of normal humans during earth-horizontal axis rotation
Wall, Conrad, III; Furman, Joseph M. R.
1989-01-01
Horizontal eye movement responses to earth-horizontal yaw axis rotation were evaluated in 50 normal human subjects who were uniformly distributed in age (20-69 years) and each age group was then divided by gender. Subjects were rotated with eyes open in the dark, using clockwise and counter-clockwise 60 deg velocity trapezoids. The nystagmus slow component velocity is analyzed. It is shown that, despite large intersubject variability, parameters which describe earth-horizontal yaw axis responses are loosely interrelated, and some of them vary significantly with gender and age.

Intelligence quotients (IQs) were measured in 15 children hospitalized in their 1st 2 years with 3rd degree malnutrition and in their siblings of closest age who had no history of hospitalization for malnutrition. Clinical records were reviewed of 459 malnourished infants admitted to the Dr. Robert Reid Cabral Hospital in Santo Domingo between January 1976-January 1977. 230 of the children had died, and 15 of the 57 survivors who returned to the hospital for a preliminary interview were selected as subjects. Their closely aged siblings served as controls. Both groups were given Bender's visual-motor test and Weschler's intelligence scale for children. The ages of the subjects were 7-0 years and of siblings 6-13 years. Children who had spent a greater number of days in the hospital appeared to have a greater degree of mental impairment. 2 of the children with marasmus presented moderate mental retardation, 1 slight retardation, and another borderline retardation. The controls for these 5 cases included 1 moderately retarded, 2 slightly retarded, and 1 borderline case. 1 child with marasmus who was removed from his home showed a normal intelligence while his control who had remained in the home had a slight retardation. There was no consistent relationship between the cephalic perimeter and the IQ score, although 40% of the malnourished children and 30% of controls had perimeters below the normal range. 20% of cases and no controls required more than 18 months to learn to walk. Cases were also slower than controls to begin speaking and to be toilet trained. The tests showed that the control group members had somewhat higher intelligence quotients than the malnourished group. 53.2% of the malnourished children had IQs far below normal at 60-69, compared to 39.9% of controls. 93% of the study group and 87% of controls had IQs below normal values of 80-89. But there was no statistically significant difference in average IQs: 72.2 + or - 17.5 in the study group and 75

Interoceptive awareness in experienced meditators.
Khalsa, Sahib S; Rudrauf, David; Damasio, Antonio R; Davidson, Richard J; Lutz, Antoine; Tranel, Daniel
2008-07-01
Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest.

2017-12-01
Competency-based training and professional development is critical to the clinical research enterprise. Understanding research coordinators' perspectives is important for establishing a common core curriculum. The purpose of this study was to describe participants' perspectives regarding the impact of online and classroom training sessions. 27 participants among three institutions, completed a two-day classroom training session. 10 novice and seven experienced research coordinators participated in focus group interviews. Grounded theory revealed similarities in novice and experienced coordinator themes including Identifying Preferences for Instruction and Changing Self Perceptions. Differences, seen in experienced participants, focused on personal change, in the theme of Re-Assessing Skills. Infrastructure and cultural issues were evident in their theme, Promoting Leadership and Advocacy. Novice participants recommended ways to improve training via their theme of Making Programmatic Improvements. Participants reported a clear preference for classroom learning. Training played an influential role in changing participants' self-perceptions by validating their experiences. The findings provided guidance for developing a standardized curriculum. Training must be carefully tailored to the needs of participants while considering audience needs based on work experience, how technology can be used and offering content that is most urgently needed.

Bifactor model of WISC-IV: Applicability and measurement invariance in low and normal IQ groups.
Gomez, Rapson; Vance, Alasdair; Watson, Shaun
2017-07-01
This study examined the applicability and measurement invariance of the bifactor model of the 10 Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) core subtests in groups of children and adolescents (age range from 6 to 16 years) with low (IQ ≤79; N = 229; % male = 75.9) and normal (IQ ≥80; N = 816; % male = 75.0) IQ scores. Results supported this model in both groups, and there was good support for measurement invariance for this model across these groups. For all participants together, the omega hierarchical and explained common variance (ECV) values were high for the general factor and low to negligible for the specific factors. Together, the findings favor the use of the Full Scale IQ (FSIQ) scores of the WISC-IV, but not the subscale index scores. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Full Text Available Purpose: The purpose of this study was to evaluate the near point of convergence break in Turkish population with normal binocular vision and to obtain the normative data for the near point of convergence break in different age groups. Such database has not been previously reported. Material and Method: In this prospective study, 329 subjects with normal binocular vision (age range, 3-72 years were evaluated. The near point of convergence break was measured 4 times repeatedly with an accommodative target. Mean values of near point of convergence break were provided for these age groups (≤10, 11-20, 21-30, 31-40, 41-50, 51-60, and >60 years old. A statistical comparison (one-way ANOVA and post-hoc test of these values between age groups was performed. A correlation between the near point of convergence break and age was evaluated by Pearson’s correlation test. Results: The mean value for near point of convergence break was 2.46±1.88 (0.5-14 cm. Specifically, 95% of measurements in all subjects were 60 year-old age groups in the near point of convergence break values (p=0.0001, p=0.0001, p=0.006, p=0.001, p= 0.004. A mild positive correlation was observed between the increase in near point of convergence break and increase of age (r=0.355 (p<0.001. Discussion: The values derived from a relatively large study population to establish a normative database for the near point of convergence break in the Turkish population with normal binocular vision are in relevance with age. This database has not been previously reported. (Turk J Ophthalmol 2013; 43: 402-6

Smooth quantile normalization.
Hicks, Stephanie C; Okrah, Kwame; Paulson, Joseph N; Quackenbush, John; Irizarry, Rafael A; Bravo, Héctor Corrada
2018-04-01
Between-sample normalization is a critical step in genomic data analysis to remove systematic bias and unwanted technical variation in high-throughput data. Global normalization methods are based on the assumption that observed variability in global properties is due to technical reasons and are unrelated to the biology of interest. For example, some methods correct for differences in sequencing read counts by scaling features to have similar median values across samples, but these fail to reduce other forms of unwanted technical variation. Methods such as quantile normalization transform the statistical distributions across samples to be the same and assume global differences in the distribution are induced by only technical variation. However, it remains unclear how to proceed with normalization if these assumptions are violated, for example, if there are global differences in the statistical distributions between biological conditions or groups, and external information, such as negative or control features, is not available. Here, we introduce a generalization of quantile normalization, referred to as smooth quantile normalization (qsmooth), which is based on the assumption that the statistical distribution of each sample should be the same (or have the same distributional shape) within biological groups or conditions, but allowing that they may differ between groups. We illustrate the advantages of our method on several high-throughput datasets with global differences in distributions corresponding to different biological conditions. We also perform a Monte Carlo simulation study to illustrate the bias-variance tradeoff and root mean squared error of qsmooth compared to other global normalization methods. A software implementation is available from https://github.com/stephaniehicks/qsmooth.

Boiling water reactors (BWRs) have experienced stress corrosion cracking in the reactor cooling system piping resulting in adverse impacts on plant availability and personnel radiation exposure. The BWR Owners Group and EPRI have sponsored a major research and development program to provide remedies for this stress corrosion cracking problem. This work shows that the likelihood of cracking depends on the plant's water chemistry performance (environment) as well as on material condition and stress level. Plant experience and other research demonstrate that water quality also affects fuel performance and radiation field buildup in BWRs. This report,''BWR Normal Water Chemistry Guidelines: 1986 Revision,'' presents suggested generic water chemistry specifications, justifies the proposed water chemistry limits, suggests responses to out-of-specification water chemistry, discusses available chemical analysis methods as well as data management and surveillance schemes, and details the management philosophy required to successfully implement a water chemistry control program. An appendix contains recommendations for water quality of auxiliary systems. 73 refs., 20 figs., 9 tabs

Full Text Available Objective: To analyse and compare the effect of a 30-minute Heartfulness meditation session on vital parameters of experienced and new meditators. Methodology: The study conducted on a mixed group of participants include both experienced and new meditators of various age groups, Body Mass Index (BMI; patients with known illness as well as healthy volunteers. Variations in heart rate, respiratory rate and systolic blood pressure is recorded before and after a 30-minute heartfulness meditation session and analysed statistically. Results: At baseline, average heart rate (HR and systolic blood pressure (SBP is significantly lower in experienced meditators compared to new meditators. Heartfulness meditation is highly significant in moderating HR, RR and SBP. Conclusion: A 30-minute session of Heartfulness meditation produces significant relaxation of the autonomic nervous system and favourably moderates basic vital parameters across all groups. This influence is higher in New meditators particularly the younger group probably because stress is more amplified due to greater responsibilities in life and meditation is an effective tool in reducing stress. The enthusiasm and open mindedness of youth to try new things is also contributing factor for getting better benefits from the heartfulness meditation session. In the case of experienced meditators, the elderly group showed greater changes, probably because they put in the time and effort to pursue the practice of meditation seriously, and thus able to derive a greater benefit.

Full Text Available Usability is a core construct of website evaluation and inherently defined as interactive. Yet, when analysing first impressions of websites, expected usability, i.e., before use, is of interest. Here we investigate to what extend ratings of expected usability are related to (a experienced usability, i.e., ratings after use, and (b objective usability measures, i.e., task performance. Furthermore, we try to elucidate how ratings of expected usability are correlated to aesthetic judgments. In an experiment, 57 participants submitted expected usability ratings after the presentation of website screenshots in three viewing-time conditions (50, 500, and 10,000 ms and after an interactive task (experienced usability. Additionally, objective usability measures (task completion and duration and subjective aesthetics evaluations were recorded for each website. The results at both the group and individual level show that expected usability ratings are not significantly related either to experienced usability or objective usability measures. Instead, they are highly correlated with aesthetics ratings. Taken together, our results highlight the need for interaction in empirical website usability testing, even when exploring very early usability impressions. In our study, user ratings of expected usability were no valid proxy neither for objective usability nor for experienced website usability.

Full Text Available Background: The effect of correcting static vision on sports vision is still not clear. Aim: To examine whether sports vision (depth perception [DP], dynamic visual acuity [DVA], eye movement [EM], peripheral vision [PV], and momentary vision [MV], were different among soft tennis adolescent athletes with normal vision (Group A, with refractive error and corrected with (Group B and without eyeglasses (Group C. Setting and Design: A cross-section study was conducted. Soft tennis athletes aged 10–13 who played softball tennis for 2–5 years, and who were without any ocular diseases and without visual training for the past 3 months were recruited. Materials and Methods: DPs were measured in an absolute deviation (mm between a moving rod and fixing rod (approaching at 25 mm/s, receding at 25 mm/s, approaching at 50 mm/s, receding at 50 mm/s using electric DP tester. A smaller deviation represented better DP. DVA, EM, PV, and MV were measured on a scale from 1 (worse to 10 (best using ATHLEVISION software. Statistical Analysis: Chi-square test and Kruskal–Wallis test was used to compare the data among the three study groups. Results: A total of 73 athletes (37 in Group A, 8 in Group B, 28 in Group C were enrolled in this study. All four items of DP showed significant difference among the three study groups (P = 0.0051, 0.0004, 0.0095, 0.0021. PV displayed significant difference among the three study groups (P = 0.0044. There was no significant difference in DVA, EM, and MV among the three study groups. Conclusions: Significant better DP and PV were seen among soft tennis adolescent athletes with normal vision than those with refractive error regardless whether they had eyeglasses corrected. On the other hand, DVA, EM, and MV were similar among the three study groups.

To compare the effect of commercially available solution and compounded ointment formulations of dorzolamide(2%)-timolol(0.5%) on intraocular pressure (IOP) of normal horses. Eighteen clinically normal horses. A randomized, masked prospective design was used with horses divided into two equal groups. One eye of each horse was selected for topical ophthalmic treatment with either 0.2 mL of dorzolamide(2%)-timolol(0.5%) solution or 0.2 g of dorzolamide(2%)-timolol(0.5%) ointment every 12 h for 5 days. The contralateral eye of horses in both groups was untreated. Rebound tonometry was performed every 6 h starting 2 days prior to and ending 2 days after the treatment period. The mean IOP reduction in eyes treated with the solution or ointment formulations was 13%. Untreated eyes in both groups experienced a lesser but still statistically significant reduction in IOP. The IOP values did not return to baseline within 48 h of the last treatment. The commercially available solution and compounded ointment formulations of ophthalmic dorzolamide(2%)-timolol(0.5%) had similar effects on IOP in normal horses. Persistent IOP reduction following cessation of treatment may indicate prolonged drug effect or acclimation of horses to tonometry. © 2014 American College of Veterinary Ophthalmologists.

Culture and group-based emotions: could group-based emotions be dialectical?
Lu, Minjie; Hamamura, Takeshi; Doosje, Bertjan; Suzuki, Satoko; Takemura, Kosuke
2017-08-01
Group-based emotions are experienced when individuals are engaged in emotion-provoking events that implicate the in-group. This research examines the complexity of group-based emotions, specifically a concurrence of positive and negative emotions, focusing on the role of dialecticism, or a set of folk beliefs prevalent in Asian cultures that views nature and objects as constantly changing, inherently contradictory, and fundamentally interconnected. Study 1 found that dialecticism is positively associated with the complexity of Chinese participants' group-based emotions after reading a scenario depicting a positive intergroup experience. Study 2 found that Chinese participants experienced more complex group-based emotions compared with Dutch participants in an intergroup situation and that this cultural difference was mediated by dialecticism. Study 3 manipulated dialecticism and confirmed its causal effect on complex group-based emotions. These studies also suggested the role of a balanced appraisal of an intergroup situation as a mediating factor.

Full Text Available Introduction: Chronic use of opiates is associated with a wide range of neuropsychological deficits. Therefore, this study aimed to evaluate one of the neuropsychological functions, updating function of working memory, in three groups, including substance abusers (heroin and opium, those under treatment with methadone, and normal controls. Methods:The method of this study was causal-comparative. Ninty individuals in three groups, including substance abusers (n = 30, those under treatment with methadone (n = 30, and normal controls (n = 30 were selected from people referred to the addiction treatment Clinics in Shiraz (2015 with the purposeful sampling method. All subjects were evaluated regarding working memory updating and self-reported mental effort scale and the results were analyzed by Multiple Analysis of Variance (MANOVA test and Tukey post hoc test with SPSS software (version 23. Results:The results showed a significant difference between the three groups in the updating function of working memory; so that effectiveness and efficiency of processing in the normal group was better than the other two groups and the performance effectiveness and efficiency of processing in the group under methadone treatment was better than substance abusers group. conclusions:substance abuse has a negative effect on neurological function. Given that the group of methadone treatment had better performance in the updating function of working memory than the group of substance abusers, these results provide hope that the effects of examined drugs on working memory is not permanent and we can look for psychological interventions to treat these patients and prevent problems recurrence.

Bilican, F Işıl; Soygüt, Gonca
2015-01-01
This study explored professional characteristics of psychotherapists in Turkey, examined the changes in their professional developmental processes, and compared the professional characteristics of the trainees and experienced therapists. The participants were 88 psychotherapists, including trainee (N=37) and experienced (N=51) psychotherapists in Turkey. They completed the Development of Psychotherapists International Study-Common Core Questionnaire (DPCCQ), developed by the Collaborative Research Network. The participants identified with the cognitive theoretical orientation most often. 30% of the participants had more than two salient orientations. The most prevalent therapy modality was individual, followed by couples, family, and group psychotherapy. Ongoing supervision rate was 44%. Trainees scored lower on effectiveness in engaging patients in a working alliance, feeling natural while working with patients, effectiveness in communicating their understanding and concern to their patients, and feeling confident in their role as a therapist. Experienced therapists made changes in the therapeutic contract and invited collaboration from families more compared to the trainees. 63% of the variance in Healing Involvement was explained by Overall Career Development, Currently Experienced Growth, being influenced by the humanistic approach, and the impact of the main therapeutic environment; 26% of the variance in Stressful Involvement was explained by the length of official supervision received and having control over the length of therapy sessions. Therapists were more cognitively oriented, less eclectic, and had less supervision compared to their international counterparts. Experienced therapists were more flexible, natural, and confident than the trainees. Supervision, a supportive work environment, the humanistic approach, and investing in career development were essential to providing a healing experience.

Full Text Available Background Cognitive processes play a significant role in both the negative and positive consequences of traumatic experiences. The aim of this research was to investigate the role of rumination in the occurrence of positive effects, in the form of posttraumatic growth, of experienced traumatic events. Participants and procedure Data were collected from 227 subjects who had experienced traumatic events, including cancer patients (31.30%, women who had experienced domestic violence (39.20%, and medical rescue workers exposed to traumatic events at work (29.50%. The age of participants ranged from 19 to 67 years (M = 40.12, SD = 13.28. The Posttraumatic Growth Inventory was used to measure positive changes, and the Event Related Rumination Inventory was used to assess the two types of ruminations (intrusive and deliberate. Results Both types of ruminations (intrusive and deliberate were positively correlated with the level of posttraumatic growth in the group of cancer patients, and deliberate ruminations were associated with posttraumatic growth in the group of women who had experienced domestic violence and in the medical rescue workers. The results of regression analysis confirmed a significant role of deliberate rumination. Conclusions The study of ruminations allows us to better explain the mechanisms underlying the consequences of traumatic experiences.

Microaggressions experienced by persons with mental illnesses: An exploratory study.
Gonzales, Lauren; Davidoff, Kristin C; Nadal, Kevin L; Yanos, Philip T
2015-09-01
Microaggressions are subtle verbal or behavioral communications of disparaging messages to people based upon membership in a socially marginalized group. Their negative impact has been demonstrated for racial/ethnic groups, gender, sexual orientation, and physical disability, but currently no research exists on microaggressions as experienced by persons with mental illnesses. Qualitative data were gathered from 4 focus groups with 2 samples: adult mental health consumers in an assertive community treatment program and college students with mental illness diagnoses. Focus group transcripts were then analyzed using an open coding approach (Strauss & Corbin, 1990) to identify hierarchical themes and categories. Five major themes were identified, including invalidation, assumption of inferiority, fear of mental illness, shaming of mental illness, and second class citizen. Perpetrators of microaggressions were most commonly identified as being close friends, family members, and authority figures. Importantly, participants reported experiencing more overt discrimination experiences than subtle microaggression experiences. Reported negative outcomes related to microaggression experiences included isolation, negative emotions, and treatment nonadherence. Reported consequences of microaggressions have important implications for mental health treatment, especially as perpetrators were reported to include treatment providers and were usually unaware of such negative social exchanges. Loss of social support reported by participants and the frequent occurrence of microaggressions within close relationships implies these experiences could contribute to internalization of stigmatizing attitudes toward mental illness. Directions for future research include an investigation of motivation and reasoning behind perpetration of microaggressions against persons with mental illnesses. (c) 2015 APA, all rights reserved).

It was hypothesized that, by comparing matched subjects with major differences in these dental diseases, but yet normal saliva flow rates, it would be possible to obtain data on the effect of saliva composition on dental disease isolated from the effect of the flow rate. Thus, the aim of the study was to compare the major physicochemical characteristics of stimulated whole saliva in three groups of 85 subjects, each with normal saliva flow rates and at least 24 remaining teeth. A group with very little dental disease (healthy), a group with dental erosion (erosion) and a group with very high caries experience (caries) were chosen. Furthermore, the aim was to determine whether differences among groups could also be found on an individual level. Although it was not possible to retrieve three groups whose members were completely identical, the present study points in the direction that, on a group level, subjects with very little dental disease seemed to have a more favorable physicochemical saliva composition with respect to higher calcium, phosphate, bicarbonate, pH, degree of saturation with respect to hydroxyapatite and a lower critical pH (p dental erosion (p dental caries and erosion in single individuals.

For singular perturbation problems, the renormalization group (RG) method of Chen, Goldenfeld, and Oono [Phys. Rev. E. 49 (1994) 4502-4511] has been shown to be an effective general approach for deriving reduced or amplitude equations that govern the long time dynamics of the system. It has been applied to a variety of problems traditionally analyzed using disparate methods, including the method of multiple scales, boundary layer theory, the WKBJ method, the Poincaré-Lindstedt method, the method of averaging, and others. In this article, we show how the RG method may be used to generate normal forms for large classes of ordinary differential equations. First, we apply the RG method to systems with autonomous perturbations, and we show that the reduced or amplitude equations generated by the RG method are equivalent to the classical Poincaré-Birkhoff normal forms for these systems up to and including terms of O(ɛ2), where ɛ is the perturbation parameter. This analysis establishes our approach and generalizes to higher order. Second, we apply the RG method to systems with nonautonomous perturbations, and we show that the reduced or amplitude equations so generated constitute time-asymptotic normal forms, which are based on KBM averages. Moreover, for both classes of problems, we show that the main coordinate changes are equivalent, up to translations between the spaces in which they are defined. In this manner, our results show that the RG method offers a new approach for deriving normal forms for nonautonomous systems, and it offers advantages since one can typically more readily identify resonant terms from naive perturbation expansions than from the nonautonomous vector fields themselves. Finally, we establish how well the solution to the RG equations approximates the solution of the original equations on time scales of O(1/ɛ).

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

Youth experiencing homelessness are at a risk for a variety of adverse outcomes. Given the widespread use of the internet and social media, these new technologies may be used to address their needs and for outreach purposes. However, little is known about how this group uses these resources. This study investigated how homeless adolescents use these technologies for general and health-related purposes, whether the scope of their use changes with housing status, and their interest in a website dedicated to youth experiencing homelessness. A convenience sample of youth aged 18 to 21 years was recruited from a youth-specific homeless shelter. All participants completed a 47-item survey, with 10 individuals completing a semistructured interview. Descriptive statistics, exact testing, logistic regression, and generalized estimating equation modeling was performed for quantitative data analysis. Interviews were transcribed verbatim, and NVivo 10 (QSR International) was employed to facilitate double coding and thematic analysis. A total of 87 participants completed the survey with a mean age of 19.4 (SD 1.1) years. While experiencing homelessness, 56% (49/87) accessed the internet at least once a day, with 86% (75/87) accessing once a week. Access to a smartphone was associated with a 3.03 greater odds of accessing the internet and was the most frequently used device (66% of participants, 57/87). While experiencing homelessness, subjects reported a 68% decreased odds in internet access frequency (odds ratio [OR] 0.32, Psocial media use (OR 0.13, P=.01). Ten participants completed the semistructured interview. Several themes were identified, including (1) changes in internet behaviors while experiencing homelessness, (2) health status as a major concern and reason for Internet use, and (3) interest in a website dedicated to youth experiencing homelessness. While experiencing homelessness, participants indicated their behaviors were more goal-oriented and less focused on

In Group 1 Per/Ind was initiated in newly diagnosed patients (n = 7032; in Group 2 Per/Ind replaced previous therapy in patients already treated but having either their BP still uncontrolled or experiencing side-effects (n = 7423; in Group 3 Per/Ind was added to previous treatment in patients with persistently high BP (n = 3483. BP was considered normalized when ≤ 140/90 mm Hg. A multivariate analysis for predictors of BP normalization was performed.Results: Subjects were on average 62 years old and had a baseline BP of 162.3/93.6 mm Hg. After treatment with Per/Ind, BP normalization was reached in 69.6% of patients in the Initiation group, 67.5% in the Replacement Group, and 67.4% in the Add-on Group (where patients were more frequently at risk, diabetic, or with target organ damage. Mean decreases in systolic BP of 22.8 mm Hg and in diastolic BP of 12.4 mm Hg were recorded. Conclusions: This trial was established to reflect everyday clinical practice, and a treatment strategy based on the Per/Ind combination, administered as initial, replacement, or add-on therapy, led to normalization rates that were superior to those observed in Europe in routine practice. These results support recent hypertension guidelines which encourage the use of combination therapy in the management of arterial hypertension.Keywords: perindopril, indapamide, blood

To assess and compare the effectiveness of a simulation-based approach to change drivers' attitudes toward cellular phone use while driving for younger novice and older experienced drivers. Thirty young novice drivers were tested on a driving simulator in this study. Their performance in dealing with driving tasks was measured for a single task and dual tasks (driving while using a cellular phone) and compared to 30 older experienced drivers tested previously in another study. Half of the younger drivers received video-based feedback regarding their performance in the two conditions, with an emphasis on the contribution of dual-tasking to degraded performance. The other half did not receive any performance feedback. Drivers' perceptions and attitudes toward cellular phone use while driving were investigated by a questionnaire before, immediately after, and again one month following the simulation-based testing for both groups of drivers (feedback; no feedback). All drivers (including the novice and experienced) reported willingness to engage in driving and talking on a cellular phone in some situations. The simulated driving test showed that a secondary cellular phone task significantly degraded driving performance for both the novice and the experienced drivers. The feedback treatment group (both the novice and the experienced) showed significant attitude change toward cellular phone use while driving (toward being less favorable), whereas the control group had no attitude change. At the one-month follow-up, the benefit of feedback was sustained more so in the experienced driver group than the novice driver group, although both groups still benefited relative to the control conditions. Simulation-based feedback training is promising for short-term education in novice drivers but may be more effective in the long-term for drivers with higher levels of experience. Drivers with more experience appear to have a greater, more sustained benefit from the training than

Women face societal and cultural barriers to breastfeeding. These challenges have been investigated in international studies and U.S. public opinion polls; however, mothers' experiences with breastfeeding in public in the United States remain unexplored. Research aim: The aim of this study was to describe the experiences of obese and normal-weight women with breastfeeding in public in central New York. Pregnant women ( N = 26) in central New York who intended to breastfeed and were either normal weight or obese were enrolled during their third trimester. A longitudinal, qualitative study was conducted to obtain information about women's experiences from birth through 3 to 6 months postpartum. Interviews were audio recorded, transcribed, and verified for accuracy. Transcripts were analyzed iteratively using conventional content analysis. The concept of "public" was situational rather than a set of physical places; women experienced challenges while breastfeeding around others in private locations that were indistinguishable from those they encountered in places typically considered public. Women experienced social and physical awkwardness including perceived lack of acceptability, fear of confrontation, exposure, and positioning difficulties. They used strategies to reduce awkwardness, for example, being "discreet" and minimizing breastfeeding around other people. Obese women experienced similar challenges but to a greater degree than normal-weight women. "Breastfeeding around others" described mother's experiences more accurately than "breastfeeding in public" and was experienced as awkward both socially and physically, particularly by obese women. Strategies are needed to normalize breastfeeding in the United States and to prepare mothers for the challenges of breastfeeding around others.

The purpose of this study was to determine the effect of supramaximal sprint interval training (SIT), body weight reduction, and a combination of both treatments on peak and average anaerobic power to weight ratio (PPOan:Wt, APOan:Wt) by manipulating peak and average anaerobic power output (PPOan, APOan) and body weight (BW) in experienced cyclists. Participants (N = 34, age = 38.0 +/- 7.1 years) were assigned to 4 groups for a 10-week study. One group performed twice-weekly SIT sessions on a cycle ergometer while maintaining body weight (SIT). A second group did not perform SIT but intentionally reduced body weight (WR). A third group simultaneously performed SIT sessions and reduced body weight (SIT+WR). A control group cycled in their normal routine and maintained body weight (CON). The 30-second Wingate Test assessed pretest and posttest POan:Wt scores. There was a significant mean increase (p weight (kg) decreased significantly in WR and SIT + WR (80.3 +/- 13.7 to 75.3 +/- 11.9 and 78.9 +/- 10.8 to 73.4 +/- 10.8, respectively). The results demonstrate that cyclists can use SIT sessions and body weight reduction as singular training interventions to effect significant increases in anaerobic power to weight ratio, which has been correlated to enhanced aerobic cycling performance. However, the treatments were not effective as combined interventions, as there was no significant change in either PPOan:Wt or APOan:Wt in SIT + WR.

To examine the prevalence of dyslexia and Meares-Irlen syndrome (MIS) among female students and determine their level of visual stress in comparison with normal subjects. A random sample of 450 female medical students of King Saud University Riyadh (age range, 18-30y) responded to a wide range of questions designed to accomplish the aims of this study. The detailed questionnaire consisted of 54 questions with 12 questions enquiring on ocular history and demography of participants while 42 questions were on visual symptoms. Items were categorized into critical and non-critical questions (CQ and NCQ) and were rated on four point Likert scale. Based on the responses obtained, the subjects were grouped into normal (control), dyslexic with or without MIS (Group 1) and subjects with MIS only (Group 2). Responses were analysed as averages and mean scores were calculated and compared between groups using one way analysis of variance to evaluate total visual stress score (TVSS=NCQ+CQ), critical and non-critical visual stress scores. The relationship between categorical variables such as age, handedness and condition were assessed with Chi-square test. The completion rate was 97.6% and majority of the respondents (92%) were normal readers, 2% dyslexic and 6% had MIS. They were age-matched. More than half of the participants had visited an eye care practitioner in the last 2y. About 13% were recommended eye exercises and one participant experienced pattern glare. Hand preference was not associated with any condition but Group 1 subjects (3/9, 33%) were significantly more likely to be diagnosed of lazy eye than Group 2 (2/27, 7%) and control (27/414, 7%) subjects. The mean±SD of TVSS responses were 63±14 and it was 44±9 for CQ and 19±5 for NCQ. Responses from all three variables were normally distributed but the CQ responses were on the average more positive (82%) in Group 2 and less positive (46%) in Group 1 than control. With NCQ, the responses were equally less positive

Intrinsic rewards experienced by a group of dentists working with underserved populations.
Gardner, S P; Roberts-Thomson, K F; Winning, T A; Peterson, R
2014-09-01
The aim of this study was to explore, using qualitative methods, the intrinsic reasons why dentists work with underserved groups. Minority and marginalized groups of Australians suffer a greater burden of dental disease than the general population due to disparities in accessing care. Recruitment and retention of dentists to care for underserved groups is problematic due to personal, professional and structural reasons. What drives dentists to work with underserved groups is not widely known. Sixteen dentists were recruited using 'snowball' purposeful sampling. Semi-structured in-depth interviews were conducted. Thematic analysis was conducted on the transcriptions to identify themes. Five key themes emerged: (1) 'tapped on the shoulder', being personally approached or invited; (2) 'dental school experience', the challenges faced as a student; (3) 'empathic concern', the non-judgemental expressions of care toward others; (4) 'resilience', the ability to bounce back after setbacks; (5) 'intrinsic reward', the personal gain and satisfaction received. This study focuses on the intrinsic rewards which were found to be simple, unexpected, and associated with relieving pain, community engagement and making a difference. Emphasizing personal fulfilment and intrinsic reward could be useful when promoting dentistry as a career and when encouraging graduates to consider working with disadvantaged groups. © 2014 Australian Dental Association.

Full Text Available In this case–control study, we aimed to assess the intervention effects of four-session eye movement desensitization and reprocessing (EMDR on reducing the severity of disaster-related anxiety, general anxiety, and depressive symptoms in Taiwanese adolescents who experienced Typhoon Morakot. A total of 83 adolescents with posttraumatic stress disorder related to Typhoon Morakot, major depressive disorder, or current moderate or high suicide risk after experiencing Typhoon Morakot were allocated to a four-session course of EMDR (N = 41 or to treatment as usual (TAU; N = 42. A multivariate analysis of covariance was performed to examine the effects of EMDR in reducing the severity of disaster-related anxiety, general anxiety, and depressive symptoms in adolescents by using preintervention severity values as covariates. The multivariate analysis of covariance results indicated that the EMDR group exhibited significantly lower preintervention severity values of general anxiety and depression than did the TAU group. In addition, the preintervention severity value of disaster-related anxiety in the EMDR group was lower than that in the TAU group (p = 0.05. The results of this study support that EMDR could alleviate general anxiety and depressive symptoms and reduce disaster-related anxiety in adolescents experiencing major traumatic disasters.

Full Text Available Consensus on whether physical condition affects the risk of gravity-induced loss of consciousness (G-LOC has not been reached, and most previous studies about the issue did not include well-experienced aviators. We compared the physical conditions of well-experienced young aviators according to the occurrence of G-LOC during human centrifuge training.Among 361 young male aviators on active flight duty with experience in high performance aircrafts for at least 2 years, 350 had full data available and were reviewed in this study. We divided the aviators into the G-LOC group and the non-G-LOC group according to their human centrifuge training results. We then compared their basic characteristics, body composition, physical fitness level, and pulmonary function.Twenty nine aviators (8.3% who experienced G-LOC during human centrifuge training in their first trials were classified into the G-LOC group. There was no difference in physical condition of aviators between the two groups.Young aviators with experience in G-LOC showed no difference in physical condition such as muscle mass, strength, and general endurance from the aviators with no such experience. Although more studies are needed, physical condition does not seem to be a significant determinant of G-LOC among the experienced aviators.

Objective: No research has been conducted on facial emotional recognition on patients with borderline personality disorder (BPD) and schizotypal personality disorder (SPD). The present study aimed at comparing facial emotion recognition in these patients with the general population. The neurocognitive processing of emotions can show the pathologic style of these 2 disorders. Method: Twenty BPD patients, 16 SPD patients, and 20 healthy individuals were selected by available sampling method. Structural Clinical Interview for Axis II, Millon Personality Inventory, Beck Depression Inventory and Facial Emotional Recognition Test was were conducted for all participants. Discussion: The results of one way ANOVA and Scheffe's post hoc test analysis revealed significant differences in neuropsychology assessment of facial emotional recognition between BPD and SPD patients with normal group (p = 0/001). A significant difference was found in emotion recognition of fear between the 2 groups of BPD and normal population (p = 0/008). A significant difference was observed between SPD patients and control group in emotion recognition of wonder (p = 0/04(. The obtained results indicated a deficit in negative emotion recognition, especially disgust emotion, thus, it can be concluded that these patients have the same neurocognitive profile in the emotion domain.

The aim of this investigation was to compare perceptions of nurses exposed to short or longer term shift work and their experiences working under this type of scheduling. Shift work is a crucial component of nurses' working lives, ensuring continuous care for patients. This study fills a research gap around the personal experiences of shift working nurses and the strategies used to manage the impacts of shift work. Qualitative case study design. Constructivist methodology, including in-depth semi-structured interviews conducted in 2015, was used for the study. Iterative review and inductive analysis of transcripts from nine recently graduated nurses and twelve experienced nurses enabled identification and verification of key themes. Three main areas of difference between new and experienced nurses relating to shift work challenges in a nursing environment emerged: perceptions about the utility of working in shifts, coping strategies and social support at home and work. Most experienced nurses found shift work advantageous, especially those with dependents. Coping strategies included flexible shift arrangements in both groups. Experienced nurses detailed the importance of support from family and friends while inexperienced nurses described feeling disconnected from social supports. Experienced nurses cited a lack of support from nursing managers as problematic. Findings suggest shift selection mitigated challenges of shift work for both inexperienced and experienced nurses, indicating autonomous roster selection is critical. Similarly, social support at work from senior nurses and management and at home played an important role in nurses' coping. © 2017 John Wiley & Sons Ltd.

Full Text Available Objectives: Violence is a widespread problem that occurs all over the word among all ages, genders, races, educational level and socio- economic groups. The aim of this study was to investigate modeling of different processes that could account for the link between experiencing spouse abuse in women and psychology, psychopathology, social and demographic factors. Methods: Data were gathered through a family violence survey study. 230 married women participated in this study. Participants were selected by a multi-cluster sampling method from 4 different randomized regions of Tehran. They completed 1 Conflict Tactic Scale-2, 2 Personal and Relationship Profile, 3 Symptoms Check List Inventory, 4 Marital Attitude Survey, 5 Social and Demographic Measure. Results: Based on participants’ scores in Conflict Tactics Scale-2, women who were experiencing violence (victims were recognized and in compare to non-experiencing women (non-victims a model of family violence victimization was draw. This model showed the paths from psychology, psychopathology, Social and Demographic factors to experiencing violence. Discussion: Based on the model with a series of paths which may act as effective determinants for experiencing violence (family violence victimization in women, habilitation services must consider the influence of each factor which may change or modify by some recognized mediating interventions .So, it may be concluded that based on present study, a reduction of psychopathology would have a beneficial impact over experiencing spousal violence.

This study advances the current literature investigating the relationship between contextual out-group exposure, inter-group attitudes and the role of inter-group contact. Firstly, it introduces the concept of contact-valence into this relationship; that is, whether contact is experienced positively or negatively. Secondly, it presents a comparative analysis of how processes of out-group exposure and frequency of (valenced) contact affect prejudice across both neighbourhoods and workplaces. Applying path analysis modelling to a nationally-representative sample of white British individuals in England, we demonstrate, across both contexts, that increasing out-group exposure is associated with higher rates of both positively- and negatively-valenced contact. This results in exposure exhibiting both positive and negative indirect associations with prejudice via more frequent inter-group mixing. These countervailing contact-pathways help explain how out-group exposure is associated with inter-group attitudes. In neighbourhoods, increasing numbers of individuals experiencing positive-contact suppress an otherwise negative effect of neighbourhood diversity (driven partly by increasing numbers of individuals reporting negative contact). Across workplaces the effect differs such that increasing numbers of individuals experiencing negative-contact suppress an otherwise positive effect of workplace diversity (driven largely by increasing numbers of individuals experiencing positive contact).

This study utilized multiple data sources to examine the beliefs about learning and teaching physics and the instructional practices of five beginning teachers and seven experienced teachers from Singapore. Our study was implemented in the unique context of teachers teaching the topic of electricity to students grouped according to academic abilities. The topic of electricity is one of the most difficult physics topics for students to understand and for teachers to teach. It was found that the experienced teachers, compared to the beginning teachers, tended to have beliefs about teaching and learning physics that are closer to constructivist views. The majority of the teachers, particularly the beginning teachers, espoused beliefs about learning physics that were incongruent with their beliefs about teaching physics. Although transmission-oriented and teacher-directed practices dominated the classroom lessons of both groups of teachers, more elements of constructivist instruction were found in the classroom lessons of the experienced teachers. It was also found that the classroom practices of the teachers, especially those in their inductive years of teaching, were more aligned with their beliefs about learning physics than their beliefs about teaching physics.

A comparative study was conducted on the 20 knees of 10 females with normal knee joints (age, 22-35 years) and on 7 knees of 7 patients with subluxation syndrome (age, 15-24 years), using axial radiography and CT. In axial radiography where the angle of knee flexion was 30 deg or 60 deg, no significant difference was recognized between the two groups with respect to tilting angle, patellofemoral angle, congruence angle and lateral shift. However, a significant difference was found using CT. Thus, CT was considered useful for diagnosis. Because of these results, all 7 cases underwent surgery for detachment of the lateral side and tightening of the medial side. Three cases underwent shifting of the tibial tuberosity to the anteromedial side, resulting in a favourable outcome. Here, we report the study. (author).

2017-01-01
Objectives To explore the views and experiences of people who are homeless and those supporting them regarding conversations and approaches to palliative care Setting Data were collected between October 2015 and October 2016 in homeless hostels and day centres and with staff from primary and secondary healthcare providers and social care services from three London boroughs. Participants People experiencing homelessness (n=28), formerly homeless people (n=10), health and social care providers (n=48), hostel staff (n=30) and outreach staff (n=10). Methods In this qualitative descriptive study, participants were recruited to interviews and focus groups across three London boroughs. Views and experiences of end-of-life care were explored with people with personal experience of homelessness, health and social care professionals and hostel and outreach staff. Saturation was reached when no new themes emerged from discussions. Results 28 focus groups and 10 individual interviews were conducted. Participants highlighted that conversations exploring future care preferences and palliative care with people experiencing homelessness are rare. Themes identified as challenges to such conversations included attitudes to death; the recovery focused nature of services for people experiencing homelessness; uncertainty regarding prognosis and place of care; and fear of negative impact. Conclusions This research highlights the need for a different approach to supporting people who are homeless and are experiencing advanced ill health, one that incorporates uncertainty and promotes well-being, dignity and choice. We propose parallel planning and mapping as a way of working with uncertainty. We acknowledge that these approaches will not always be straightforward, nor will they be suitable for everyone, yet moving the focus of conversations about the future away from death and dying, towards the present and the future may facilitate conversations and enable the wishes of people who are

2013-12-01
Full Text Available The purpose is to compare similarities and divergences in how the concepts of Lean and barriers to Lean are described by key informants at a production unit in a large manufacturing company and two emergency health care units in Sweden. Data was collected via semi-structured interviews and analyzed with the constant comparative method (CCM and Porras and Robertson’s (1992 change model. : In both organizations, the view of Lean changed from a toolbox to a human behavior view. Eight barriers were experienced in both organizations. Three barriers were unique to manufacturing or to health care, respectively. Nine barriers were elements of social factors; five were elements of organizing arrangements. Only people practically involved and responsible for the implementation at the two organizations participated in the study. Persons responsible for implementing Lean should consider organizational arrangements and social factors in order to limit barriers to successful implementation. Most research on Lean has been about successful Lean implementations. This study focuses on how Lean is viewed and what barriers personnel in manufacturing and health care have experienced. In comparing the barriers to Lean experienced in the two groups, common, archetypical, and unique barriers for manufacturing and health care can be identified, thus contributing to knowledge about barriers to Lean implementation.

2014-11-01
This research established collective nostalgia as a group-level emotion and ascertained the benefits it confers on the group. In Study 1, participants who reflected on a nostalgic event they had experienced together with ingroup members (collective nostalgia) evaluated the ingroup more positively and reported stronger intentions to approach (and not avoid) ingroup members than those who recalled a nostalgic event they had experienced individually (personal nostalgia), those who reflected on a lucky event they had experienced together with ingroup members (collective positive), and those who did not recall an event (no recall). In Study 2, collective (vs. personal) nostalgia strengthened behavioral intentions to support the ingroup more so than did recalling an ordinary collective (vs. personal) event. Increased collective self-esteem mediated this effect. In Study 3, collective nostalgia (compared with recall of an ordinary collective event) led participants to sacrifice money in order to punish a transgression perpetrated against an ingroup member. This effect of collective nostalgia was more pronounced when social identification was high (compared with low). Finally, in Study 4, collective nostalgia converged toward the group average (i.e., was socially shared) when participants thought of themselves in terms of their group membership. The findings underscore the viability of studying nostalgia at multiple levels of analysis and highlight the significance of collective nostalgia for understanding group-level attitudes, global action tendencies, specific behavioral intentions, and behavior.

Performance of work is related with experiencing various emotions, from positive - indicating full satisfaction with work, to negative - describing failures, and even harm caused by work. Such emotions are also experienced by children engaged in work on family farms. The objective of the study is the determination of emotions experienced in association with performing agricultural work in childhood, and indication of the factors conditioning the occurrence of positive and negative emotions. The study was conducted by the method of a diagnostic survey using a questionnaire technique, and covered a group of 482 adults from agricultural families. In childhood, positive emotions related with the performance of work are more often experienced than negative emotions. The occurrence of positive emotions is positively related with willingness to perform work activities, working time, respondent's age, age at which a child started to perform work, and age at which a child discontinued helping on a farm. The occurrence of negative emotions is positively related with unwillingness to perform work, performing work activities beyond the physical capabilities of a child, neglecting school duties, missing classes at school due to work, and with working time. With work performed in childhood are associated positive and negative emotions experienced in childhood and adulthood. The performance of work in childhood shapes emotions experienced by an adult which may affect his/her quality of life and functioning in adulthood.

2011-01-01
Full Text Available Abstract Background Trunk asymmetry and vertebral rotation, at times observed in the normal spine, resemble the characteristics of adolescent idiopathic scoliosis (AIS. Right thoracic curvature has also been reported in the normal spine. If it is determined that the features of right thoracic side curvature in the normal spine are the same as those observed in AIS, these findings might provide a basis for elucidating the etiology of this condition. For this reason, we investigated right thoracic curvature in the normal spine. Methods For normal spinal measurements, 1,200 patients who underwent a posteroanterior chest radiographs were evaluated. These consisted of 400 children (ages 4-9, 400 adolescents (ages 10-19 and 400 adults (ages 20-29, with each group comprised of both genders. The exclusion criteria were obvious chest and spinal diseases. As side curvature is minimal in normal spines and the range at which curvature is measured is difficult to ascertain, first the typical curvature range in scoliosis patients was determined and then the Cobb angle in normal spines was measured using the same range as the scoliosis curve, from T5 to T12. Right thoracic curvature was given a positive value. The curve pattern was organized in each collective three groups: neutral (from -1 degree to 1 degree, right (> +1 degree, and left ( Results In child group, Cobb angle in left was 120, in neutral was 125 and in right was 155. In adolescent group, Cobb angle in left was 70, in neutral was 114 and in right was 216. In adult group, Cobb angle in left was 46, in neutral was 102 and in right was 252. The curvature pattern shifts to the right side in the adolescent group (p Conclusions Based on standing chest radiographic measurements, a right thoracic curvature was observed in normal spines after adolescence.

Spinal cord (SC) pathology is common in multiple sclerosis (MS), and measures of SC-atrophy are increasingly utilized. Normalization reduces biological variation of structural measurements unrelated to disease, but optimal parameters for SC volume (SCV)-normalization remain unclear. Using a variety of normalization factors and clinical measures, we assessed the effect of SCV normalization on detecting group differences and clarifying clinical-radiological correlations in MS. 3T cervical SC-MRI was performed in 133 MS cases and 11 healthy controls (HC). Clinical assessment included expanded disability status scale (EDSS), MS functional composite (MSFC), quantitative hip-flexion strength ("strength"), and vibration sensation threshold ("vibration"). SCV between C3 and C4 was measured and normalized individually by subject height, SC-length, and intracranial volume (ICV). There were group differences in raw-SCV and after normalization by height and length (MS vs. HC; progressive vs. relapsing MS-subtypes, P normalization by length (EDSS:r = -.43; MSFC:r = .33; strength:r = .38; vibration:r = -.40), and height (EDSS:r = -.26; MSFC:r = .28; strength:r = .22; vibration:r = -.29), but diminished with normalization by ICV (EDSS:r = -.23; MSFC:r = -.10; strength:r = .23; vibration:r = -.35). In relapsing MS, normalization by length allowed statistical detection of correlations that were not apparent with raw-SCV. SCV-normalization by length improves the ability to detect group differences, strengthens clinical-radiological correlations, and is particularly relevant in settings of subtle disease-related SC-atrophy in MS. SCV-normalization by length may enhance the clinical utility of measures of SC-atrophy. Copyright © 2014 by the American Society of Neuroimaging.

Background Thallium-201 myocardial perfusion image (MPI) is commonly used to detect coronary artery disease in patients with chest pain. Although a normal thallium-201 MPI result is generally considered to be a good prognosis and further coronary angiogram is not recommended, there are still a few patients who suffer from unexpected acute coronary events. The aim of this study was to investigate the clinical prognosis in patients with normal thallium-201 MPI. Methods From January 2006 to August 2012, a total 22,003 patients undergoing thallium-201 MPI in one tertiary center were screened. Of these, 8092 patients had normal results and were investigated retrospectively. During follow-up, 54 patients underwent coronary angiogram because of refractory typical angina pectoris or unexpected acute coronary events. These 54 patients were divided into 2 groups: group I consisted of 26 (48.1%) patients with angiography-proven significant coronary artery stenosis, and group II consisted of 28 (51.9%) patients without significant stenosis. Results Patients in group I had a higher prevalence of prior coronary stenting and electrocardiographic features of ST depression compared with patients in group II. The multivariate analysis demonstrated that both prior coronary stenting and ST depression were risk predictors of unexpected acute coronary events in the patients with normal thallium-201 MPI [odds ratio (OR), 5.93; 95% confidence interval (CI): 1.03-34.06, p = 0.05 and OR, 7.10; 95% CI: 1.28-39.51, p = 0.03,respectively]. Conclusions Although there is a low incidence of unexpected acute coronary events in patients with chest pain and normal thallium-201 MPI, physicians should be aware of the potentials risk in certain patients in this specific population.

Maintaining stable levels of anticoagulation using warfarin therapy is challenging. Few studies have examined the stability of the international normalized ratio (INR) in patients with nonvalvular atrial fibrillation (NVAF) who have had ≥6 months' exposure to warfarin anticoagulation for stroke prevention. Our objective was to describe INR control in NVAF patients who had been receiving warfarin for at least 6 months. Using retrospective patient data from the CoagClinic™ database, we analyzed data from NVAF patients treated with warfarin to assess the quality of INR control and possible predictors of poor INR control. Time within, above, and below the recommended INR range (2.0-3.0) was calculated for patients who had received warfarin for ≥6 months and had three or more INR values. The analysis also assessed INR patterns and resource utilization of patients with an INR >4.0. Logistic regression models were used to determine factors associated with poor INR control. Patients (n = 9433) had an average of 1.6 measurements per 30 days. Mean follow-up time was 544 days. Approximately 39% of INR values were out of range, with 23% of INR values being 3.0. Mean percent time with INR in therapeutic range was 67%; INR 3.0 was 14%. Patients with more than one reading of INR >4.0 (~39%) required an average of one more visit and took 3 weeks to return to an in-range INR. Male sex and age >75 years were predictive of better INR control, whereas a history of heart failure or diabetes were predictive of out-of-range INR values. However, patient characteristics did not predict the likelihood of INR >4.0. Out-of-range INR values remain frequent in patients with NVAF treated with warfarin. Exposure to high INR values was common, resulting in increased resource utilization.

Turns (pirouettes) are an important movement in ballet and may be affected by "lateral bias". This study investigated physiological differences exhibited by experienced and novice dancers, respectively, when performing pirouette with dominant and non-dominant leg supports, respectively. Thirteen novice and 13 experienced dancers performed turns on dominant or non-dominant legs. The maximum ankle plantarflexion, knee extension and hip extension were measured during the single-leg support phase. The inclination angle of rotation axis is the angle between instantaneous rotation axis and global vertical axis in the early single-leg support phase. Both groups exhibited a greater hip extension, knee extension, and ankle plantarflexion when performing a turn on the non-dominant leg. For experienced dancers, the inclination angle of rotation axis during the pre-swing phase was generally smaller for dominant leg support than non-dominant leg. However, no significant difference was found in inclination angle of rotation axis of novice dancers. For experienced dancers, an improved performance is obtained when using the dominant leg for support. By contrast, for novice dancers, the performance is independent of choice of support leg. The significant lateral bias in experienced dancers indicates the possible influence of training. That is, repetitive rehearsal on the preferred leg strengthens the impact of side dominance in experienced dancers.

In xeroderma pigmentosum, an inherited disorder of defective DNA repair, post-uv colony-forming ability of fibroblasts from patients in complementation groups A through F correlates with the patients' neurological status. The first xeroderma pigmentosum patient assigned to the recently discovered group G had the neurological abnormalities of XP. Researchers have determined the post-uv colony-forming ability of cultured fibroblasts from this patient and from 5 more control donors. Log-phase fibroblasts were irradiated with 254 nm uv light from a germicidal lamp, trypsinized, and replated at known densities. After 2 to 4 weeks' incubation the cells were fixed, stained and scored for colony formation. The strains' post-uv colony-forming ability curves were obtained by plotting the log of the percent remaining post-uv colony-forming ability as a function of the uv dose. The post-uv colony-forming ability of 2 of the 5 new normal strains was in the previously defined control donor zone, but that of the other 3 extended down to the level of the most resistant xeroderma pigmentosum strain. The post-uv colony-forming ability curve of the group G fibroblasts was not significantly different from the curves of the group D fibroblast strains from patients with clinical histories similar to that of the group G patient

Full Text Available Objective: No research has been conducted on facial emotional recognition on patients with borderline personality disorder (BPD and schizotypal personality disorder (SPD. The present study aimed at comparing facial emotion recognition in these patients with the general population. The neurocognitive processing of emotions can show the pathologic style of these 2 disorders. Method: Twenty BPD patients, 16 SPD patients, and 20 healthy individuals were selected by available sampling method. Structural Clinical Interview for Axis II, Millon Personality Inventory, Beck Depression Inventory and Facial Emotional Recognition Test was were conducted for all participants.Discussion: The results of one way ANOVA and Scheffe’s post hoc test analysis revealed significant differences in neuropsychology assessment of facial emotional recognition between BPD and SPD patients with normal group (p = 0/001. A significant difference was found in emotion recognition of fear between the 2 groups of BPD and normal population (p = 0/008. A significant difference was observed between SPD patients and control group in emotion recognition of wonder (p = 0/04(.The obtained results indicated a deficit in negative emotion recognition, especially disgust emotion, thus, it can be concluded that these patients have the same neurocognitive profile in the emotion domain.

The enhanced-sensitivity Trofile assay (Monogram Biosciences) was used to retest coreceptor use at both study screening and study entry for 118 treatment-experienced subjects in AIDS Clinical Trials Group A5211 who had CCR5-tropic (R5) virus detected by the original Trofile assay at study screening. Among 90 recipients of vicriviroc, a significantly (P< .001) greater mean reduction in HIV-1 RNA was observed in 72 subjects with R5 virus versus 15 subjects reclassified as having dual/mixed-tropic viruses at screening: -1.11 versus -0.09 log(10) copies/mL at day 14 and -1.91 versus -0.57 log(10) copies/mL at week 24, respectively. Results suggest that the enhanced-sensitivity assay is a better screening tool for determining patient eligibility for CCR5 antagonist therapy.

Women residing at domestic violence shelters (S group) were nearly 11 times more likely to report that their partner had hurt or killed pets than a comparison group of women who said they had not experienced intimate violence (NS group). Reports of threatened harm to pets were more than 4 times higher for the S group. Using the Conflict Tactics Scale, the authors demonstrated that severe physical violence was a significant predictor of pet abuse. The vast majority of shelter women described being emotionally close to their pets and distraught by the abuse family pets experienced. Children were often exposed to pet abuse, and most reported being distressed by these experiences. A substantial minority of S-group women reported that their concern for their pets' welfare prevented them from seeking shelter sooner. This seemed truer for women without children, who may have had stronger pet attachments. This obstacle to seeking safety should be addressed by domestic violence agencies.

Full Text Available Over past decade, the Iowa gambling task (IGT has been utilized to test various decision deficits induced by neurological damage or psychiatric disorders. The IGT has recently been standardized for identifying 13 different neuropsychological disorders. Neuropsychological patients choose bad decks frequently, and normal subjects prefer good EV decks. However, the IGT has several validity and reliability problems. Some research groups have pointed out that the validity of IGT is influenced by the personality and emotional state of subjects. Additionally, several other studies have proposed that the prominent deck B phenomenon (PDB phenomenon – that is, normal subjects preferring bad deck B – may be the most serious problem confronting IGT validity. Specifically, deck B offers a high frequency of gains but negative EV. In the standard IGT administration, choice behavior can be understood with reference to gain-loss frequency (GLF rather than inferred future consequences (EV, the basic assumption of IGT. Furthermore, using two different criteria (basic assumption vs. professional norm results in significantly different classification results. Therefore, we recruited 72 normal subjects to test the validity and reliability of IGT. Each subject performed three runs of the computer-based clinical IGT version. The PDB phenomenon has been observed to a significant degree in the first and second stages of the clinical IGT version. Obviously, validity, reliability and the practice effect were unstable between two given stages. The present form of the clinical IGT version has only one stage, so its use should be reconsidered for examining normal decision makers; results from patient groups must also be interpreted with great care. GLF could be the main factor to be considered in establishing the constructional validity and reliability of the clinical IGT version.

This study aimed to evaluate the stigma and its correlates among patients with severe mental disorders. Patients with diagnosis of schizophrenia (N = 707), bipolar disorder (N = 344) and recurrent depressive disorder (N = 352) currently in clinical remission from 14 participating centres were assessed on Internalized Stigma of Mental Illness Scale (ISMIS). Patients with diagnosis of schizophrenia experienced higher level of alienation, sterotype endorsement, discrimination experience and total stigma when compared to patients with bipolar disorder and recurrent depressive disorder. Patients with bipolar disorder experienced higher stigma than those with recurrent depressive disorder in the domain of stigma resistance only. Overall compared to affective disorder groups, higher proportion of patients with schizophrenia reported stigma in all the domains of ISMIS. In general in all the 3 diagnostic groups' stigma was associated with shorter duration of illness, shorter duration of treatment and younger age of onset. To conclude, this study suggests that compared to affective disorder, patients with schizophrenia experience higher self stigma. Higher level of stigma is experienced during the early phase of illness. Stigma intervention programs must focus on patients during the initial phase of illness in order to reduce the negative consequences of stigma. Copyright © 2017 Elsevier B.V. All rights reserved.

This article reflects on my early [student] experiences in learning to undertake radiographic reporting and uses critical incidents to highlight two areas of error during this period. These errors include perceptual (optical illusions and, in particular, the Mach band effect) and lack of subject specific knowledge (specifically anatomical knowledge--especially of normal anatomical variants). These two errors are analysed in the wider context of radiological error and the difficulty in reaching consensus even between experienced reporters.

This study was conducted to determine the effects of extracts obtained from both normal and denervated muscles on different muscle types. Wistar rats were used and were divided into a control group and four experimental groups. Each experimental group was treated intraperitoneally during 10 consecutive days with a different extract. These extracts were obtained from normal soleus muscle, denervated soleus, normal extensor digitorum longus, and denervated extensor digitorum longus. Following treatment, the soleus and extensor digitorum longus muscles were obtained for study under optic and transmission electron microscope; morphometric parameters and myogenic responses were also analyzed. The results demonstrated that the treatment with normal soleus muscle and denervated soleus muscle extracts provoked hypertrophy and increased myogenic activity. In contrast, treatment with extracts from the normal and denervated EDL had a different effect depending on the muscle analyzed. In the soleus muscle it provoked hypertrophy of type I fibers and increased myogenic activity, while in the extensor digitorum longus atrophy of the type II fibers was observed without changes in myogenic activity. This suggests that the muscular responses of atrophy and hypertrophy may depend on different factors related to the muscle type which could be related to innervation.

To explore the views and experiences of people who are homeless and those supporting them regarding conversations and approaches to palliative care SETTING: Data were collected between October 2015 and October 2016 in homeless hostels and day centres and with staff from primary and secondary healthcare providers and social care services from three London boroughs. People experiencing homelessness (n=28), formerly homeless people (n=10), health and social care providers (n=48), hostel staff (n=30) and outreach staff (n=10 ). METHODS: In this qualitative descriptive study, participants were recruited to interviews and focus groups across three London boroughs. Views and experiences of end-of-life care were explored with people with personal experience of homelessness, health and social care professionals and hostel and outreach staff. Saturation was reached when no new themes emerged from discussions. 28 focus groups and 10 individual interviews were conducted. Participants highlighted that conversations exploring future care preferences and palliative care with people experiencing homelessness are rare. Themes identified as challenges to such conversations included attitudes to death; the recovery focused nature of services for people experiencing homelessness; uncertainty regarding prognosis and place of care; and fear of negative impact. This research highlights the need for a different approach to supporting people who are homeless and are experiencing advanced ill health, one that incorporates uncertainty and promotes well-being, dignity and choice. We propose parallel planning and mapping as a way of working with uncertainty. We acknowledge that these approaches will not always be straightforward, nor will they be suitable for everyone, yet moving the focus of conversations about the future away from death and dying, towards the present and the future may facilitate conversations and enable the wishes of people who are homeless to be known and explored.

Ordered groups and infinite permutation groups
1996-01-01
The subjects of ordered groups and of infinite permutation groups have long en joyed a symbiotic relationship. Although the two subjects come from very different sources, they have in certain ways come together, and each has derived considerable benefit from the other. My own personal contact with this interaction began in 1961. I had done Ph. D. work on sequence convergence in totally ordered groups under the direction of Paul Conrad. In the process, I had encountered "pseudo-convergent" sequences in an ordered group G, which are like Cauchy sequences, except that the differences be tween terms of large index approach not 0 but a convex subgroup G of G. If G is normal, then such sequences are conveniently described as Cauchy sequences in the quotient ordered group GIG. If G is not normal, of course GIG has no group structure, though it is still a totally ordered set. The best that can be said is that the elements of G permute GIG in an order-preserving fashion. In independent investigations around that t...

Normal motor milestone development for use to promote child care
Directory of Open Access Journals (Sweden)
Mahdin A. Husaini
2016-10-01
Full Text Available Background Motor behavior is an essential aspect of child development, and usually assessed in terms of age of achievement of motor milestone. The early detection of infants experiencing subtle delays in motor maturation can allow early intervention in developmental problems. Intervention can be more effective if delays are identified early. In order to facilitate the identification of early delays, the Center of Nutrition and Foods Research and Development in Bogor has designed a simple tool to monitor the child (aged 3 to 18 months motor development. Objective To develop an observable of normal gross motor maturation for use to detect deviance or motor delay. Methods A total of 2100 healthy children, aged 3-18 months, from high socio-economic group, in urban and suburban areas, were studied. Body length, weight and motor development were measured on all children. Gross motor development was measured 17 pre selected milestones: lie, sit, crawl, creep, stand Mth assistance, walk with assistance, stand alone, walk alone, and run. Results There were no differences between males and females in the comparison of attainment motor maturation therefore a sex combined curve was developed. Conclusion The curve of normal motor milestone development can be used as a tool to evaluate motor development over time, and/or as a child development card for use in primary health care.

Online Support Groups for Depression
Directory of Open Access Journals (Sweden)
Louise Breuer
2015-04-01
Full Text Available This mixed-methods study aimed to explore the initial process of engagement with an online support group (OSG for depression. Fifteen British National Health Service patients experiencing depression who had not previously used an OSG for depression were offered facilitated access to an existing peer-to-peer OSG for 10 weeks. Pre- and post-measures of depression, social support, and self-stigma were taken in addition to a weekly measure of OSG usage. A follow-up qualitative interview was conducted with a subsample of nine participants. Depression and self-stigma reduced over the 10-week period, but perceived social support did not change. There was no evidence of adverse outcomes. Perceived benefits of OSG participation included connection to others, normalization of depression, and stigma reduction. However, engagement with the OSG was generally low. Barriers included concerns over causing harm to others or being harmed oneself, feeling different from others in the group, and fears of being judged by others. OSGs may potentially reduce depressive symptoms and perceived self-stigma. However, considerable barriers may hinder people with depression from engaging with OSGs. Further work is needed to determine who will benefit most from participating in OSGs for depression and how best to facilitate engagement.

Experienced and potential medical tourists' service quality expectations.
Guiry, Michael; Scott, Jeannie J; Vequist, David G
2013-01-01
The paper's aim is to compare experienced and potential US medical tourists' foreign health service-quality expectations. Data were collected via an online survey involving 1,588 US consumers engaging or expressing an interest in medical tourism. The sample included 219 experienced and 1,369 potential medical tourists. Respondents completed a SERVQUAL questionnaire. Mann-Whitney U-tests were used to determine significant differences between experienced and potential US medical tourists' service-quality expectations. For all five service-quality dimensions (tangibles, reliability, responsiveness, assurance and empathy) experienced medical tourists had significantly lower expectations than potential medical tourists. Experienced medical tourists also had significantly lower service-quality expectations than potential medical tourists for 11 individual SERVQUAL items. Results suggest using experience level to segment medical tourists. The study also has implications for managing medical tourist service-quality expectations at service delivery point and via external marketing communications. Managing medical tourists' service quality expectations is important since expectations can significantly influence choice processes, their experience and post-consumption behavior. This study is the first to compare experienced and potential US medical tourist service-quality expectations. The study establishes a foundation for future service-quality expectations research in the rapidly growing medical tourism industry.

Objectives To quantify the incremental benefit of computer-assisted-detection (CAD) for polyps, for inexperienced readers versus experienced readers of CT colonography. Methods 10 inexperienced and 16 experienced radiologists interpreted 102 colonography studies unassisted and with CAD utilised in a concurrent paradigm. They indicated any polyps detected on a study sheet. Readers’ interpretations were compared against a ground-truth reference standard: 46 studies were normal and 56 had at least one polyp (132 polyps in total). The primary study outcome was the difference in CAD net benefit (a combination of change in sensitivity and change in specificity with CAD, weighted towards sensitivity) for detection of patients with polyps. Results Inexperienced readers’ per-patient sensitivity rose from 39.1% to 53.2% with CAD and specificity fell from 94.1% to 88.0%, both statistically significant. Experienced readers’ sensitivity rose from 57.5% to 62.1% and specificity fell from 91.0% to 88.3%, both non-significant. Net benefit with CAD assistance was significant for inexperienced readers but not for experienced readers: 11.2% (95%CI 3.1% to 18.9%) versus 3.2% (95%CI -1.9% to 8.3%) respectively. Conclusions Concurrent CAD resulted in a significant net benefit when used by inexperienced readers to identify patients with polyps by CT colonography. The net benefit was nearly four times the magnitude of that observed for experienced readers. Experienced readers did not benefit significantly from concurrent CAD. PMID:26355745

A decrease in insulin sensitivity enhances adipose tissue lipolysis helping early lactation cows counteracting their energy deficit. However, excessive lipolysis poses serious health risks for cows, and its underlying mechanisms are not clearly understood. The present study used targeted ESI-LC-MS/MS-based metabolomics and indirect insulin sensitivity measurements to evaluate metabolic alterations in the serum of dairy cows of various parities experiencing variable lipolysis early postpartum. Thirty (12 primiparous and 18 multiparous) cows of Holstein Friesian and Simmental breeds, fed the same diet and kept under the same management conditions, were sampled at d 21 postpartum and classified as low (n = 10), medium (n = 8), and high (n = 12) lipolysis groups, based on serum concentration of nonesterified fatty acids. Overall, excessive lipolysis in the high group came along with impaired estimated insulin sensitivity and characteristic shifts in acylcarnitine, sphingomyelin, phosphatidylcholine and lysophospholipid metabolome profiles compared to the low group. From the detected phosphatidylcholines mainly those with diacyl-residues showed differences among lipolysis groups. Furthermore, more than half of the detected sphingomyelins were increased in cows experiencing high lipomobilization. Additionally, strong differences in serum acylcarnitines were noticed among lipolysis groups. The study suggests an altered serum phospholipidome in dairy cows associated with an increase in certain long-chain sphingomyelins and the progression of disturbed insulin function. In conclusion, the present study revealed 37 key metabolites as part of alterations in the synthesis or breakdown of sphingolipids and phospholipids associated with lowered estimated insulin sensitivity and excessive lipolysis in early-lactating cows.

Factors other than ischemia may alter right ventricular function both at rest and on exercise. Normal volunteers differ from cardiac patients with normal coronary arteries with regard to their left ventricular response to exercise. This study examined changes in right ventricular function on exercise in 21 normal volunteers and 13 patients with normal coronary arteries, using first-pass radionuclide angiography. There were large ranges of right ventricular ejection fraction in the two groups, both at rest and on exercise. Resting right ventricular ejection fraction was 40.2 +/- 10.6% (mean +/- SD) in the volunteers and 38.6 +/- 9.7% in the patients, p = not significant, and on exercise rose significantly in both groups to 46.1 +/- 9.9% and 45.8 +/- 9.7%, respectively. The difference between the groups was not significant. In both groups some subjects with high resting values showed large decreases in ejection fraction on exercise, and there were significant negative correlations between resting ejection fraction and the change on exercise, r = -0.59 (p less than 0.01) in volunteers, and r = -0.66 (p less than 0.05) in patients. Older volunteers tended to have lower rest and exercise ejection fractions, but there was no difference between normotensive and hypertensive patients in their rest or exercise values. In conclusion, changes in right ventricular function on exercise are similar in normal volunteers and in patients with normal coronary arteries. Some subjects show decreases in right ventricular ejection fraction on exercise which do not appear to be related to ischemia

Struggles for medical legitimacy among women experiencing sexual pain: A qualitative study.
Braksmajer, Amy
2018-04-01
Given the prominent role of medical institutions in defining what is "healthy" and "normal," many women turn to medicine when experiencing pain during intercourse (dyspareunia). The medical encounter can become a contest between patients and providers when physicians do not grant legitimacy to patients' claims of illness. Drawing on interviews conducted from 2007 to 2008 and 2011 to 2012 with 32 women experiencing dyspareunia (ages 18-60 years) and living in New York City and its surrounding areas, this study examined women's and their physicians' claims regarding bodily expertise, particularly women's perceptions of physician invalidation, their understanding of this invalidation as gendered, and the consequences for women's pursuit of medicalization. Women overwhelmingly sought a medical diagnosis for their dyspareunia, in which they believed that providers would relieve uncertainty about its origin, give treatment alternatives, and permit them to avoid sexual activity. When providers did not give diagnoses, women reported feeling that their bodily self-knowledge was dismissed and their symptoms were attributed to psychosomatic causes. Furthermore, some women linked their perceptions of invalidation to both historical and contemporary forms of gender bias. Exploration of women's struggles for medical legitimacy may lead to a better understanding of the processes by which medicalization of female sexuality takes place.

Subjective expansion of extended time-spans in experienced meditators
Directory of Open Access Journals (Sweden)
Marc eWittmann
2015-01-01
Full Text Available Experienced meditators typically report that they experience time slowing down in meditation practise as well as in everyday life. Conceptually this phenomenon may be understood through functional states of mindfulness, i.e. by attention regulation, body awareness, emotion regulation, and enhanced memory. However, hardly any systematic empirical work exists regarding the experience of time in meditators. In the current cross-sectional study, we investigated whether 42 experienced mindfulness meditation practitioners (with on average 10 years of experience showed differences in the experience of time as compared to 42 controls without any meditation experience matched for age, sex and education. The perception of time was assessed with a battery of psychophysical tasks assessing the accuracy of prospective time judgments in duration discrimination, duration reproduction and time estimation in the milliseconds to minutes range as well with several psychometric instruments related to subjective time such as the Zimbardo Time Perspective Inventory, the Barrett Impulsivity Scale and the Freiburg Mindfulness Inventory. In addition, subjective time judgments on the current passage of time and retrospective time ranges were assessed. While subjective judgements of time were found to be significantly different between the two groups on several scales, no differences in duration estimates in the psychophysical tasks were detected. Regarding subjective time, mindfulness meditators experienced less time pressure, more time dilation, and a general slower passage of time. Moreover, they felt that the last week and the last month passed more slowly. Overall, although no intergroup differences in psychophysical tasks were detected, the reported findings demonstrate a close association between mindfulness meditation and the subjective feeling of the passage of time captured by psychometric instruments.

Explaining attrition and decreased effectiveness of experienced teachers: A research synthesis.
Torenbeek, Marjolein; Peters, Velibor
2017-01-01
Teacher retention and development of the full potential of teachers is important at a national level in order to be able to belong to the top world economies. A number of studies suggests that part of the group of experienced teachers with more than 20 years of experience perform didactically at a lower level than would be expected and are at a greater risk for attrition. The aim of the present study is to find explanations for this by making use of the Job Demands Resources Model. Specific demands of the teaching profession, interpersonal demands related to the developmental stage of experienced teachers, job resources and personal resources in relation to health and motivation are explored by reviewing a vast amount of literature. The proposed conceptual model is an extension of the Job Demands Resources Model with the inclusion of personal demands related to adulthood and personal resources. The resulting model provides us with clues on how attrition and decreased performance could be counteracted.

Cystic fibrosis with normal sweat chloride concentration: case report
Directory of Open Access Journals (Sweden)
Silva Filho Luiz Vicente Ferreira da
2003-01-01
Full Text Available Cystic fibrosis is a genetic disease usually diagnosed by abnormal sweat testing. We report a case of an 18-year-old female with bronchiectasis, chronic P. aeruginosa infection, and normal sweat chloride concentrations who experienced rapid decrease of lung function and clinical deterioration despite treatment. Given the high suspicion ofcystic fibrosis, broad genotyping testing was performed, showing a compound heterozygous with deltaF508 and 3849+10kb C->T mutations, therefore confirming cystic fibrosis diagnosis. Although the sweat chloride test remains the gold standard for the diagnosis of cystic fibrosis, alternative diagnostic tests such as genotyping and electrophysiologic measurements must be performed if there is suspicion of cystic fibrosis, despite normal or borderline sweat chloride levels.

2018-03-01
The multiple challenges that ethnoracial homeless individuals experiencing mental illness face are well documented. However, little is known about how this homeless subpopulation copes with the compounding stressors of racial discrimination, homelessness and mental illness. This study is an in-depth investigation of the personal perceived strengths, attitudes and coping behaviors of homeless adults of diverse ethnoracial backgrounds experiencing homelessness and mental illness in Toronto, Canada. Using qualitative methods, 36 in-depth semi-structured interviews were conducted to capture the perspectives of ethnoracial homeless participants with mental illness on coping and resilience. Transcripts were analyzed using thematic analysis. Similar to prior findings in the general homeless population, study participants recognized personal strengths and attitudes as great sources of coping and resilience, describing hope and optimism, self-esteem and confidence, insight into their challenges and spirituality as instrumental to overcoming current challenges. In addition, participants described several coping strategies, including seeking support from family, friends and professionals; socializing with peers; engaging in meaningful activities; distancing from overwhelming challenges; and finding an anchor. Findings suggest that homeless adults with mental illness from ethnoracial groups use similar coping strategies and sources of resilience with the general homeless population and highlight the need for existing services to foster hope, recognize and support individual coping strategies and sources of resilience of homeless individuals experiencing complex challenges.

1995-10-01
To identify the frequency of psychological and emotional abuse, gender discrimination, verbal sexual harassment, physical sexual harassment, physical assault, and homophobia experienced by general internists. Cross-sectional survey. Canadian general internal medicine practices. The overall response rate was 70.6% (984/1,393); the 501 respondents who classified themselves as general internists were studied. Three-fourths of the internists experienced psychological and emotional abuse at the hands of patients, and 38% of the women and 26% of the men experienced physical assault by patients. The majority of the female internists experienced gender discrimination by patients (67%) and by physician peers (56%). Forty-five percent of the women experienced verbal sexual harassment by patients, and 22% experienced physical sexual harassment by patients. The male internists experienced verbal sexual harassment from nurses slightly more often than the female internists did (19% vs 13%, p > 0.05). Verbal sexual harassment by male colleagues was reported by 35% of the female internists, and physical sexual harassment was reported by 11%. Approximately 40% of general internists reported homophobic remarks by both health care team members and patients. Abuse, discrimination, and homophobia are prevalent in the internal medicine workplace. A direct, progressive, multidisciplinary approach is necessary to label and address these problems.

This study aimed to establish a normal range for ankle systolic blood pressure (SBP). A total of 948 subjects who had normal brachial SBP (90-139 mmHg) at investigation were enrolled. Supine BP of four limbs was simultaneously measured using four automatic BP measurement devices. The ankle-arm difference (An-a) on SBP of both sides was calculated. Two methods were used for establishing normal range of ankle SBP: the 99% method was decided on the 99% reference range of actual ankle BP, and the An-a method was the sum of An-a and the low or up limits of normal arm SBP (90-139 mmHg). Whether in the right or left side, the ankle SBP was significantly higher than the arm SBP (right: 137.1 ± 16.9 vs 119.7 ± 11.4 mmHg, P<0.05). Based on the 99% method, the normal range of ankle SBP was 94~181 mmHg for the total population, 84~166 mmHg for the young (18-44 y), 107~176 mmHg for the middle-aged(45-59 y) and 113~179 mmHg for the elderly (≥ 60 y) group. As the An-a on SBP was 13 mmHg in the young group and 20 mmHg in both middle-aged and elderly groups, the normal range of ankle SBP on the An-a method was 103-153 mmHg for young and 110-160 mmHg for middle-elderly subjects. A primary reference for normal ankle SBP was suggested as 100-165 mmHg in the young and 110-170 mmHg in the middle-elderly subjects.

Young people who have experienced homelessness, foster care, or poverty are among the most disadvantaged in society. This review examines whether young people who have these experiences differ from their non-disadvantaged peers with respect to their cognitive skills and abilities, and whether cognitive profiles differ between these three groups. Three electronic databases were systematically searched for articles published between 1 January 1995 and 1 February 2015 on cognitive functioning among young people aged 15 to 24 years who have experienced homelessness, foster care, or poverty. Articles were screened using pre-determined inclusion criteria, then the data were extracted, and its quality assessed. A total of 31 studies were included. Compared to non-disadvantaged youth or published norms, cognitive performance was generally found to be impaired in young people who had experienced homelessness, foster care, or poverty. A common area of difficulty across all groups is working memory. General cognitive functioning, attention, and executive function deficits are shared by the homeless and poverty groups. Creativity emerges as a potential strength for homeless young people. The cognitive functioning of young people with experiences of impermanent housing and poverty has been relatively neglected and more research is needed to further establish cognitive profiles and replicate the findings reviewed here. As some aspects of cognitive functioning may show improvement with training, these could represent a target for intervention.

Full Text Available Aim of this research was to describe the nature, direction and severity of anticipated and experienced discrimination reported by people with schizophrenia. We applied interview to 50 patients with diagnosis of schizophrenia in two psychiatric hospitals in Belgrade. Discrimination was measured with discrimination and stigma scale (DISC which produce 3 subscores, positive experienced discrimination, negative experienced discrimination and anticipated discrimination. The same scale was used in cross-cultural research in 27 european countries. Results have shown that participants from Serbia do not recognize discrimination in all areas of life equally. The discrimination recognized is more frequentlly negative then positive and is associated with existentially important realms of life. Due to anticipated discrimination participants in our study prevent themselves from looking for a close relationship. Anticipated discrimination could not be predicted on the grounds of experienced, positive or negative discrimination.

The article regards the predictors in selection of normative (participation in meetings, signing petitions, etc. vs. nonnormative (strike, violent actions, etc. forms of protest behavior (perception of unfairness, self-efficacy, social identity, ideas of out-group. The carried out analysis showed that high self-efficacy, idea of out-group members as equal participants of interaction and experiencing of emotion of anger lead to the choice of various normative protest behavior. Low self-efficacy, steady social identity (including politicized identity, experiencing the emotion of contempt to out-group members often lead to choice of nonnormative forms. In conclusion the article regards the link of various predictors with the choice of individual and group forms of protest and analyzes the possible directions for further empirical studies.

Full Text Available Learning burnout is a phenomenon in which students hold a negative attitude to curriculum learning, which manifests in aspects of physiology, psychology, behavior and interpersonal communication. China attaches great importance to higher education, colleges and universities shoulder the important task of training national modernization personnel. The problem of university students’ learning burnout has become a social phenomenon that cannot be ignored. Normal university students are one of the important groups of college students, and this phenomenon of learning burnout may also occur among them. English majors are the backbone of English teachers in primary and secondary schools in the future. The learning status of these groups affects the overall quality of teaching in normal colleges and universities and, more importantly, the quality of teachers in primary and secondary schools in the future. This paper first reviews the definition of learning burnout and the research methods of measurement. Subsequently, it investigates the learning burnout of English matriculation students by taking the first-year English majors of Jiangxi Normal University as an example. In this way, this research is hoped to promote the study on learning burnout not only among English normal students but also other normal students.

Experiencing maternity care: the care received and perceptions of women from different ethnic groups
2013-01-01
Background According to the Office for National Statistics, approximately a quarter of women giving birth in England and Wales are from minority ethnic groups. Previous work has indicated that these women have poorer pregnancy outcomes than White women and poorer experience of maternity care, sometimes encountering stereotyping and racism. The aims of this study were to examine service use and perceptions of care in ethnic minority women from different groups compared to White women. Methods Secondary analysis of data from a survey of women in 2010 was undertaken. The questionnaire asked about women’s experience of care during pregnancy, labour and birth, and the postnatal period, as well as demographic factors. Ethnicity was grouped into eight categories: White, Mixed, Indian, Pakistani, Bangladeshi, Black Caribbean, Black African, and Other ethnicity. Results A total of 24,319 women completed the survey. Compared to White women, women from minority ethnic groups were more likely to be younger, multiparous and without a partner. They tended to access antenatal care later in pregnancy, have fewer antenatal checks, fewer ultrasound scans and less screening. They were less likely to receive pain relief in labour and, Black African women in particular, were more likely to deliver by emergency caesarean section. Postnatally, women from minority ethnic groups had longer lengths of hospital stay and were more likely to breastfeed but they had fewer home visits from midwives. Throughout their maternity care, women from minority ethnic groups were less likely to feel spoken to so they could understand, to be treated with kindness, to be sufficiently involved in decisions and to have confidence and trust in the staff. Conclusion Women in all minority ethnic groups had a poorer experience of maternity services than White women. That this was still the case following publication of a number of national policy documents and local initiatives is a cause for concern. PMID

Elaine Scharfe
2017-10-01
Full Text Available An important cornerstone of Bowlby’s attachment theory (1969/1997 is the proposal that moving away from parents and toward peers is an indication of healthy development. In this study, we explored the benefit of the shift, not the shift itself, in a sample of emerging adults experiencing a stressful life event (i.e., the transition from university. Although the shift from parents to peers is an important cornerstone of Bowlby’s theory, this study is one of the first to test the differential effects of parent and peer networks on adjustment. In this longitudinal study, 73 participants completed surveys to assess attachment, social networks, and distress one month before completing their undergraduate degree and 6 months later. We found that participants experiencing the transition from university, who chose a peer as the first person in their network, tended to report stable scores over time whereas participants who chose a family member reported more variable scores. Interestingly, the direction of change was not different for the groups, just the magnitude of change. Furthermore, the difference in adjustment was not found when we compared the groups using the percent hierarchy method highlighting that there is a benefit of exploring primary attachment relationships when examining the influence of networks on adjustment.

Full Text Available Objective To determine the difference in blood microcirculation recovery between normal frostbite and high-altitude frostbite during the wound healing. Methods Twenty four male rats were randomly divided into control group (n=8, normal frostbite group (n=8, and high-altitude group (n=8. The normal frostbite group rats were frozen to produce mid-degree frostbite models by controlling the freezing time with liquid nitrogen penetration equipment. The high-altitude frostbite group rats were acclimated to a hypoxic and low-pressure environment for 1 week, and then the high-altitude frostbite models were constructed by the same way with liquid nitrogen penetration apparatus. On days 3, 7, 11, 15, 19, and 23 after modeling, the recovery situation of blood circulation of each group was observed with contrast ultrasonography by injecting SonoVue micro-bubble into rats' tail. Finally, the micro-bubble concentration (MC was calculated to confirm the blood circulation recovery with software Image Pro. Results At different time points, the wound area of the high-altitude frostbite group was bigger than that of the normal frostbite group, and the MC of control group was always about (27±0.2×109/ml. On day 3, 7, 11, 15, 19, and 23, the MC was significantly lower in the high-altitude frostbite group than in the control group and normal frostbite group (P<0.05. The MC of normal frostbite group was significantly lower than that of the control group on day 3, 7, 11, 15 and 19 (P<0.05.

To describe the intraoperative complications and the learning curve of microincision cataract surgery assisted by femtosecond laser (FLACS) with bimanual technique performed by an experienced surgeon. It is a prospective, observational, comparative case series. A total of 120 eyes which underwent bimanual FLACS by the same experienced surgeon during his first experience were included in the study; we considered the first 60 cases as Group A and the second 60 cases as Group B. In both groups, only nuclear sclerosis of grade 2 or 3 was included; an intraocular lens was implanted through a 1.4-mm incision. Best-corrected visual acuity (BCVA), surgically induced astigmatism (SIA), central corneal thickness and endothelial cell loss (ECL) were evaluated before and at 1 and 3 months after surgery. Intraoperative parameters, and intra- and post-operative complications were recorded. In Group A, we had femtosecond laser-related minor complications in 11 cases (18.3%) and post-operative complications in 2 cases (3.3%); in Group B, we recorded 2 cases (3.3%) of femtosecond laser-related minor complications with no post-operative complications. Mean effective phaco time (EPT) was 5.32 ± 3.68 s in Group A and 4.34 ± 2.39 s in Group B with a significant difference (p = 0.046). We recorded a significant mean BCVA improvement at 3 months in both groups (p 0.05). Finally, we found significant ECL in both groups with a significant difference between the two groups (p = 0.042). FLACS with bimanual technique and low-energy LDV Z8 is associated with a necessary initial learning curve. After the first adjustments in the surgical technique, this technology seems to be safe and effective with rapid visual recovery and it helps surgeons to standardize the crucial steps of cataract surgery.

Full Text Available Background. There are few studies devoted to assessing the impact of meditation-intensive retreats on the well-being, positive psychology and personality of experienced meditators. We aimed to assess whether a 1-month Vipassana retreat: a would increase mindfulness and well-being; b would increase prosocial personality traits; and c whether psychological changes would be mediated and/or moderated by non-attachment.Method. A controlled, non-randomized, pre-post-intervention trial was used. The intervention group was a convenience sample (n=19 of experienced meditators who participated in a 1-month Vipassana meditation retreat. The control group (n=19 comprised matched experienced meditators who did not take part in the retreat. During the retreat, the mean duration of daily practice was 8-9 hours, the diet was vegetarian and silence was compulsory. The Experiences Questionnaire (EQ, Non-Attachment Scale (NAS, Positive and Negative Affect Schedule (PANAS, Satisfaction With Life Scale (SWLS, Temperament Character Inventory Revised (TCI-R-67, Five Facets Mindfulness Questionnaire (FFMQ, Self-Other Four Immeasurables (SOFI and the MINDSENS Composite Index were administered. ANCOVAs and linear regression models were used to assess pre-post changes and mediation/moderation effects.Results. Compared to controls, retreatants showed increases in non-attachment, observing, MINDSENS, positive-affect, balance-affect and cooperativeness; and decreases in describing, negative-others, reward-dependence and self-directedness. Non-attachment had a mediating role in decentring, acting aware, non-reactivity, negative-affect, balance-affect and self-directedness; and a moderating role in describing and positive others, with both mediating and moderating effects on satisfaction with life.Conclusions. A 1-month Vipassana meditation retreat seems to yield improvements in mindfulness, well-being and personality, even in experienced meditators. Non-attachment might

Somatic experiencing treatment with social service workers following Hurricanes Katrina and Rita.
Leitch, M Laurie; Vanslyke, Jan; Allen, Marisa
2009-01-01
In a disaster, social service workers are often survivors themselves.This study examines whether somatic intervention using a brief (one to two session) stabilization model now called the Trauma Resiliency Model (TRM), which uses the skills of Somatic Experiencing (SE), can reduce the postdisaster symptoms of social service workers involved in postdisaster service delivery.The study was implemented with a nonrandom sample of 142 social service workers who were survivors of Hurricanes Katrina and Rita in New Orleans and Baton Rouge, Louisiana, two to three months after the disasters. Ninety-one participants received SE/TRM and were compared with a matched comparison group of 51 participants through the use of propensity score matching. All participants first received group psychoeducation. Results support the benefits of the brief intervention inspired by SE. The treatment group showed statistically significant gains in resiliency indicators and decreases in posttraumatic stress disorder symptoms. Although psychological symptoms increased in both groups at the three to four month follow-up, the treatment group's psychological symptoms were statistically lower than those of the comparison group.

Measurements of regional or local cerebral blood flow (CBF) by the xenon-133 inhalation method and stable xenon computerized tomography CBF (CTCBF) method were made during relaxed wakefulness and different stages of REM and non-REM sleep in normal age-matched volunteers, narcoleptics, and sleep apneics. In the awake state, CBF values were reduced in both narcoleptics and sleep apneics in the brainstem and cerebellar regions. During sleep onset, whether REM or stage I-II, CBF values were paradoxically increased in narcoleptics but decreased severely in sleep apneics, while in normal volunteers they became diffusely but more moderately decreased. In REM sleep and dreaming CBF values greatly increased, particularly in right temporo-parietal regions in subjects experiencing both visual and auditory dreaming

Bulimia nervosa in overweight and normal-weight women.
Masheb, Robin; White, Marney A
2012-02-01
The aim of the present study was to examine overweight bulimia nervosa (BN) in a community sample of women. Volunteers (n = 1964) completed self-report questionnaires of weight, binge eating, purging, and cognitive features. Participants were classified as overweight (body mass index ≥25) or normal weight (body mass index <25). Rates of BN within the overweight and normal-weight classes did not differ (6.4% vs 7.9%). Of the 131 participants identified as BN, 64% (n = 84) were classified as overweight BN and 36% (n = 47) as normal-weight BN. The overweight BN group had a greater proportion of ethnic minorities and reported significantly less restraint than the normal-weight BN group. Otherwise, the 2 groups reported similarly, even in terms of purging and depression. In summary, rates of BN did not differ between overweight and normal-weight women. Among BN participants, the majority (two thirds) were overweight. Differences in ethnicity and restraint, but little else, were found between overweight and normal-weight BN. Findings from the present study should serve to increase awareness of the weight range and ethnic diversity of BN, and highlight the need to address weight and cultural sensitivity in the identification and treatment of eating disorders.

During the last decade, more and more people have received prescriptions for ADHD drug treatment, and simultaneously the legitimacy of the ADHD diagnosis has been heavily debated among both professionals and laymen. Based on an anthropological fieldwork among adults with ADHD, I illustrate how...... the ADHD diagnosis both answers and produces existential questions on what counts as normal behaviour and emotions. The diagnosis helps the diagnosed to identify, accept and handle problems by offering concrete explanations and solutions to diffuse experienced problems. But the diagnostic process...... is not only a clarifying procedure with a straight plan for treatment and direct effects. It is also a messy affair. In a process of experimenting with drugs and attempting to determine how or whether the medication eliminates the correct symptoms the diagnosed is put in an introspective, self...

Full Text Available A pergunta título deste trabalho retoma o slogan “Ser diferente é normal”, que é parte da campanha criada para uma organização não-governamental que atende portadores de Síndrome de Down. O objetivo é a inclusão social da pessoa com deficiência e o primeiro passo foi propor a inclusão de um grupo de diferentes no grupo dito normal. No vídeo de lançamento da campanha, o diferente, identificado como normal, é mostrado por meio de exemplos – um negro com cabelo black-power, um skin-head, um corpo tatuado, um corpo feminino halterofílico, uma família hippie, uma garota com síndrome de Down. A visão da adolescente dançando reduz, de certo modo, o efeito imaginário que vai além da síndrome, uma vez que apenas o corpo com seus olhinhos puxados se destacam, e não se interrogam questões cognitivas. Minha proposta é refletir sobre o estatuto paradoxal do exemplo, tal como é trabalhado nesse vídeo: se, por definição, um exemplo mostra de fato seu pertencimento a uma classe, pode-se concluir que é exatamente por ser exemplar que ele se encontra fora dela, no exato momento em que a exibe e define. The question in the title of this paper refers to the slogan "ser diferente é normal" ("It´s normal to be different", which is part of a campaign created for a NGO that supports people with Down syndrome. The objective of the campaign is to promote the social inclusion of individuals with Down syndrome, and the first step was to propose the inclusion of a group of "differents" in the so-called normal group. The film launching the campaign shows the different identified as normal by means of examples: a black man exhibiting blackpower haircut, a skin-head, a tattooed body, an over-athletic female body, a hippie family and a girl with Down syndrome. The vision of the dancing teenager lessens the imaginary effect that surpasses the syndrome, since only her body and her little oriental eyes stand out and no cognitive issues are

This study contributes towards a better understanding of learning dynamics in doctoral supervision by analysing how learning opportunities are created in the interaction between supervisors and PhD students, using the notion of experiencing variation as a key to learning. Empirically, we have based...... the study on four video-recorded sessions, with four different PhD students and their supervisors, all from life sciences. Our analysis revealed that learning opportunities in the supervision sessions concerned either the content matter of research (for instance, understanding soil structure......), or the research methods— more specifically how to produce valid results. Our results illustrate how supervisors and PhD students create a space of learning together in their particular discipline by varying critical aspects of their research in their discussions. Situations where more openended research issues...

Full Text Available Purpose. Whistleblowing is the reporting of illegal, immoral, or illegitimate practices to persons or organizations that may affect the action. The current study compares experienced nurses to nursing students regarding their willingness to blow the whistle to protect a patient’s interests. Methods. 165 participants were divided into two groups: 82 undergraduate nursing students and 83 experienced nurses. Participants responded to two vignettes that described a colleague’s and a manager’s misconduct at work. Results. The nursing students perceived the severity of the misconduct significantly lower compared to the experienced nurses. The nursing students also ranked the internal and external whistleblowing indices higher than the nurses, but the differences did not reach statistical significance. For each of the examined internal and external indices, professional experience was found to be significant in multivariate regression analyses. Conclusions. Even though nursing students perceived the severity of the misconduct significantly lower than the experienced nurses, the students demonstrated a greater readiness to blow the whistle, both internally and externally. Recommendations for handling comparable situations are offered.

Full text: In the interpretation of cerebral perfusion scans, it is important to know the normal variation in perfusion which may occur between the cerebral hemispheres. For this reason 24 normal volunteers with no neurological or psychiatric history, and who were on no medications, had 99m Tc-HMPAO brain SPECT studies using a single headed gamma camera computer system. Oblique, coronal and sagittal images were reviewed separately by two experienced observers and any differences were resolved by consensus. Semi-quantitation was performed by summing two adjacent oblique slices and drawing right and left mirror image ROIs corresponding to the mid section level of anterior and posterior frontal lobes, anterior and posterior parietal lobes, temporal lobes and cerebellum. From the mean counts per pixel, right: left ROI ratios and ROI: cerebellar ratios were calculated. On qualitative review 6/24 subjects had mild asymmetry in tracer distribution between right and left cerebral lobes. Semi-quantitation revealed a 5-10% difference in counts between right and left ROIs in 12/24 subjects and an additional three subjects had 10-20% difference in counts between right and left temporal lobes. This study demonstrates the presence of mild asymmetry of cerebral perfusion in a significant minority of normal subjects

To explore the characteristics, motivations, ideologies, experience and perspectives of experienced medical humanitarian workers. We applied a qualitative descriptive approach and conducted in-depth semistructured interviews, containing open-ended questions with directing probes, with 44 experienced international medical aid workers from a wide range of humanitarian organisations. Interviews were coded and analysed, and themes were developed. International non-governmental organisations (INGOs) and United Nations (UN). 61% of participants were female; mean age was 41.8 years with an average of 11.8 years of humanitarian work experience with diverse major INGOs. Significant core themes included: population's rights to assistance, altruism and solidarity as motives; self-identification with the mission and directives of INGOs; shared personal and professional morals fostering collegiality; accountability towards beneficiaries in areas of programme planning and funding; burnout and emotional burdens; uncertainties in job safety and security; and uneasiness over changing humanitarian principles with increasing professionalisation of aid and shrinking humanitarian access. While dissatisfied with overall aid operations, participants were generally satisfied with their work and believed that they were well-received by, and had strong relationships with, intended beneficiaries. Despite regular use of language and ideology of rights, solidarity and concepts of accountability, tension exists between the philosophy and practical incorporation of accountability into operations. To maintain a humanitarian corps and improve aid worker retention, strategies are needed regarding management of psychosocial stresses, proactively addressing militarisation and neo-humanitarianism, and nurturing individuals' and organisations' growth with emphasis on humanitarian principles and ethical practices, and a culture of internal debate, reflection and reform.

Perineal ultrasonography is a noninvasive method that is easier than chain cystoure-thrography in the diagnosis of stress urinary incontinence(SUI). We report the findings of stress urinary incontinence at peritoneal ultrasound and its differential points form normal control. Twenty-two patients with SUI and l6 normal controls were included in our study. Aloka SSD 650 with 3.5MHz convex transducer was used, and sagittal image through the bladder, bladder base, urethrovesical junction and pubis was obtained from the vulva area, We measured thepdsterior urethrovesical angle(PUVA) at rest and stress, and calculated the difference between the two angles. We also measured the distance of bladder neck descent during stress and the diameter of proximal urethra at rest. The data were analyzed with student t-test. At rest, PUVA was 135.3 .deg. in patients with SUI group and 134.5 .deg. in normal control group(P=0.8376). During streets, PUVA was 149.5 .deg. in SUI group and 142.1 .deg. in normal group(P=0.0135). The difference PUVAs at rest and during stress was 14.2 .deg. in SUI group and 7.6 .deg. in normal group(P=0.0173). The distance of bladder neck descent during stress was 14.5mm in SUI group and 9.8mm in normal group(P=0.0029). The diameter of proxiaml urethra at rest was 4.4mm in SUI group and 3.6mm in normal group(P=0.0385). In conclusion, ultrasound parameters that include the PUVA during stress, the difference between PUVAs at rest and during stress, the distance of bladder neck descent during stress and the diameter of proximal ureyhra at rest are useful in diagnosis of the stress urinary incontinence

Deprivation as un-experienced harm?
DEFF Research Database (Denmark)
Keerus, Külli; Gjerris, Mickey; Röcklinsberg, Helena
2017-01-01
Tom Regan encapsulated his principle of harm as a prima facie direct duty not to harm experiencing subjects of a life. However, his consideration of harm as deprivation, one example of which is loss of freedom, can easily be interpreted as a harm, which may not be experienced by its subject....... This creates a gap between Regan’s criterion for moral status and his account of what our duties are. However, in comparison with three basic paradigms of welfare known in nonhuman animal welfare science, Regan’s understanding coheres with a modified version of a feelings-based paradigm: not only the immediate...... feelings of satisfaction, but also future opportunities to have such feelings, must be taken into account. Such an interpretation is compatible with Regan’s understanding of harm as deprivation. The potential source of confusion, however, lies in Regan’s own possible argumentative mistakes....

College students disproportionately experience victimization, stalking, and relationship violence when compared with other groups. Few studies explore victimization by the gender identity of college students, including those who identify as transgender. The purpose of this study is to explore the rates of violence experienced by transgender students compared with male and female college students. This study utilized the National College Health Assessment-II (NCHA-II) and included data from students ( n = 82,538) across fall 2011, 2012, and 2013. Bivariate statistics and binary logistic regression were conducted to test the relationships between gender identity and victimization. Transgender students ( n = 204) were compared with male ( n = 27,322) and female ( n = 55,012) students. After adjusting for individual factors, transgender students had higher odds of experiencing all nine types of violence when compared with males and higher odds of experiencing eight types of violence than females. Transgender students experienced the highest odds in crimes involving sexual victimization, including attempted sexual penetration (adjusted odds ratio [aOR]: 9.49, 95% confidence interval [CI] = [6.17, 14.59], d = 1.00), sexual penetration without consent (aOR: 9.06, 95% CI = [5.64, 14.53], d = 0.94), and being in a sexually abusive relationship (aOR: 6.48, 95% CI = [4.01, 10.49], d = 0.48), than did male students. Findings reveal increased odds of victimization among transgender students when compared with male and female students. Results demonstrate the need for more comprehensive violence prevention efforts in college settings.

Hemoglobin levels in normal Filipino pregnant women.
Kuizon, M D; Natera, M G; Ancheta, L P; Platon, T P; Reyes, G D; Macapinlac, M P
1981-09-01
The hemoglobin concentrations during pregnancy in Filipinos belonging to the upper income group, who were prescribed 105 mg elemental iron daily, and who had acceptable levels of transferrin saturation, were examined in an attempt to define normal levels. The hemoglobin concentrations for each trimester followed a Gaussian distribution. The hemoglobin values equal to the mean minus one standard deviation were 11.4 gm/dl for the first trimester and 10.4 gm/dl for the second and third trimesters. Using these values as the lower limits of normal, in one group of pregnant women the prevalence of anemia during the last two trimesters was found lower than that obtained when WHO levels for normal were used. Groups of women with hemoglobin of 10.4 to 10.9 gm/dl (classified anemic by WHO criteria but normal in the present study) and those with 11.0 gm/dl and above could not be distinguished on the basis of their serum ferritin levels nor on the degree of decrease in their hemoglobin concentration during pregnancy. Many subjects in both groups, however, had serum ferritin levels less than 12 ng/ml which indicate poor iron stores. It might be desirable in future studies to determine the hemoglobin cut-off point that will delineate subjects who are both non-anemic and adequate in iron stores using serum ferritin levels as criterion for the latter.

endorsement: agreeing that difficulty implies importance and disagreeing that difficulty implies impossibility improved performance. This study had a control group. Control group participants not guided to use a particular interpretation-of-experienced-difficulty mindset performed no differently than participants guided toward a difficulty-as-impossibility mindset. Results suggest that people may chronically act as if they are using a difficulty-as-impossibility mindset and may benefit from being guided to consider that experienced difficulty might imply task importance. Effect of accessible mindset on salience of academic possible selves was not stable, accessible mindset mattered in one university sample but not the other.

Full Text Available Extra-thoracic tumors send out pilot cells that attach to the pulmonary endothelium. We hypothesized that this could alter regional lung mechanics (tissue stiffening or accumulation of fluid and inflammatory cells through interactions with host cells. We explored this with serial inspiratory computed tomography (CT and image matching to assess regional changes in lung expansion.We retrospectively assessed 44 pairs of two serial CT scans on 21 sarcoma patients: 12 without lung metastases and 9 with lung metastases. For each subject, two or more serial inspiratory clinically-derived CT scans were retrospectively collected. Two research-derived control groups were included: 7 normal nonsmokers and 12 asymptomatic smokers with two inspiratory scans taken the same day or one year apart respectively. We performed image registration for local-to-local matching scans to baseline, and derived local expansion and density changes at an acinar scale. Welch two sample t test was used for comparison between groups. Statistical significance was determined with a p value < 0.05.Lung regions of metastatic sarcoma patients (but not the normal control group demonstrated an increased proportion of normalized lung expansion between the first and second CT. These hyper-expanded regions were associated with, but not limited to, visible metastatic lung lesions. Compared with the normal control group, the percent of increased normalized hyper-expanded lung in sarcoma subjects was significantly increased (p < 0.05. There was also evidence of increased lung "tissue" volume (non-air components in the hyper-expanded regions of the cancer subjects relative to non-hyper-expanded regions. "Tissue" volume increase was present in the hyper-expanded regions of metastatic and non-metastatic sarcoma subjects. This putatively could represent regional inflammation related to the presence of tumor pilot cell-host related interactions.This new quantitative CT (QCT method for linking

Cystic fibrosis transmembrane conductance regulator (CFTR) has been demonstrated to be expressed in mature spermatozoa and correlated with sperm quality. Sperm CFTR expression in fertile men is higher than that in infertile men suffering from teratospermia, asthenoteratospermia, asthenospermia and oligospermia, but it is unknown whether CFTR is correlated with sperm parameters when sperm parameters are normal. In this study, 282 healthy and fertile men with normal semen parameters were classified into three age groups, group (I): age group of 20-29 years (98 cases, 27.1 ± 6.2), group (II): age group of 30-39 years (142 cases, 33.7 ± 2.6) and group (III): age group of more than or equal to 40 years (42 cases, 44.1 ± 4.6). Sperm concentration, total count and progressive motility were analysed by computer-assisted sperm analysis. Sperm morphology was analysed by modified Papanicolaou staining. Sperm CFTR expression was conducted by indirect immunofluorescence staining. There was a significant positive correlation (P sperm progressive motility (r = 0.221) and normal morphology (r = 0.202), but there were no correlations between sperm CFTR expression and semen volume, sperm concentration, sperm total count as well as male age (P > 0.05). Our findings show that CFTR expression is associated with sperm progressive motility and normal morphology in healthy and fertile men with normal sperm parameters, but not associated with the number of spermatozoa and male age. © 2013 Blackwell Verlag GmbH.

To investigate the approaches of experienced speech-language pathologists (SLPs) to ethical reasoning and the processes they use to resolve ethical dilemmas. Ten experienced SLPs participated in in-depth interviews. A narrative approach was used to guide participants' descriptions of how they resolved ethical dilemmas. Individual narrative transcriptions were analyzed by using the participant's words to develop an ethical story that described and interpreted their responses to dilemmas. Key concepts from individual stories were then coded into group themes to reflect participants' reasoning processes. Five major themes reflected participants' approaches to ethical reasoning: (a) focusing on the well-being of the client, (b) fulfilling professional roles and responsibilities, (c) attending to professional relationships, (d) managing resources, and (e) integrating personal and professional values. SLPs demonstrated a range of ethical reasoning processes: applying bioethical principles, casuistry, and narrative reasoning when managing ethical dilemmas in the workplace. The results indicate that experienced SLPs adopted an integrated approach to ethical reasoning. They supported clients' rights to make health care choices. Bioethical principles, casuistry, and narrative reasoning provided useful frameworks for facilitating health professionals' application of codes of ethics to complex professional practice issues.

Renal length offers important information to detect or follow-up various renal diseases. The purpose of this study was to determine the kidney length of normal Korean children in relation to age, height, weight, body surface area (BSA), and body mass index (BMI). Children between 1 month and 15 years of age without urological abnormality were recruited. Children below 3rd percentile and over 97th percentile for height or weight were excluded. Both renal lengths were measured in the prone position three times and then averaged by experienced radiologists. The mean length and standard deviation for each age group was obtained, and regression equation was calculated between renal length and age, weight, height, BSA, and BMI, respectively. Renal length was measured in 550 children. Renal length grows rapidly until 24 month, while the growth rate is reduced thereafter. The regression equation for age is: renal length (mm) = 45.953 + 1.064 x age (month, ≤ 24 months) (R2 = 0.720) or 62.173 + 0.203 x age (months, > 24 months) (R2 = 0.711). The regression equation for height is: renal length (mm) = 24.494 + 0.457 x height (cm) (R2 = 0.894). The regression equation for weight is: renal length (mm) = 38.342 + 2.117 x weight (kg, ≤18 kg) (R2 = 0.852) or 64.498 + 0.646 x weight (kg, > 18 kg) (R2 = 0.651). The regression equation for BSA is: renal length (mm) = 31.622 + 61.363 x BSA (m2, ≤ 0.7) (R2 = 0.857) or 52.717 + 29.959 x BSA (m2, > 0.7) (R2 = 0.715). The regression equation for BMI is: renal length (mm) = 44.474 + 1.163 x BMI (R2 = 0.079). This study provides data on the normal renal length and its association with age, weight, height, BSA and BMI. The results of this study will guide the detection and follow-up of renal diseases in Korean children

A humanistic environment for dental schools: what are dental students experiencing?
Quick, Karin K
2014-12-01
A Commission on Dental Accreditation (CODA) standard now requires that dental schools commit to establishing a "humanistic culture and learning environment" for all members of the academic environment. The aim of this study was to identify students' perceptions of factors that affect the dental school environment and to test differences in their experiences in terms of gender and year. This picture of the existing environment was meant to serve as a first step toward creating and supporting a more humanistic academic environment. A mixed-methods approach was used for data collection during the 2009-10 and 2010-11 academic years at one U.S. dental school. Four focus groups were first conducted to explore challenges and conflicts faced by students during their dental education. A written survey informed by the focus group results was then used to obtain quantitative data. The survey response rate was 47 percent (N=188). Faculty inconsistency, cheating, and belittlement/disrespect were experienced by many of the responding dental students during their education, similar to what has been documented in medicine. These students also reported experiencing both constructive communication (90 percent) and destructive communication (up to 32 percent). The female students reported more gender discrimination and sexual harassment than their male peers, and the clinical students reported more experience with belittlement and destructive communication than the preclinical students. The results suggest that greater effort should be directed toward creating a more humanistic environment in dental schools. Based on the issues identified, steps academic institutions can take to improve these environments and student skills are outlined.

The present study was performed to assess stress-related left ventricular (LV) function variations in various patient groups and to determine if they were affected by sex or the type of stress experienced. We used thallium (Tl)-201 gated myocardial perfusion single-photon emission computed tomography (SPECT) for the analysis. A total of 270 patients were examined by electrocardiography-gated myocardial perfusion SPECT imaging to assess LV function. After injection of Tl-201 at a dose of 111 MBq at peak stress, SPECT scans were acquired at 10 min (after stress) and 3 h (rest) after injection on a three-headed camera. In the normal perfusion group, the mean LV ejection fraction (LVEF) was significantly higher, and both the end-diastolic volume index (EDVI) and end-systolic volume index (ESVI) were significantly lower in women than in men (P<0.05). Poststress stunning occurred in 29 of 98 patients (30.0%) in the ischemia group and in 42 of 90 patients (46.7%) in the fixed group. There was a significant difference in poststress stunning between bicycle ergometer stress and dipyridamole stress (P<0.05). In patients with normal perfusion, LVEF, EDVI, and ESVI determined by gated Tl-201 SPECT should be corrected for sex. In addition, the influence of the type of stress should be considered when assessing stress-related LV function variations. (author)

Background: There are few studies devoted to assessing the impact of meditation-intensive retreats on the well-being, positive psychology, and personality of experienced meditators. We aimed to assess whether a 1-month Vipassana retreat: (a) would increase mindfulness and well-being; (b) would increase prosocial personality traits; and (c) whether psychological changes would be mediated and/or moderated by non-attachment. Method: A controlled, non-randomized, pre-post-intervention trial was used. The intervention group was a convenience sample ( n = 19) of experienced meditators who participated in a 1-month Vipassana meditation retreat. The control group ( n = 19) comprised matched experienced meditators who did not take part in the retreat. During the retreat, the mean duration of daily practice was 8-9 h, the diet was vegetarian and silence was compulsory. The Experiences Questionnaire (EQ), Non-attachment Scale (NAS), Positive and Negative Affect Schedule (PANAS), Satisfaction With Life Scale (SWLS), Temperament Character Inventory Revised (TCI-R-67), Five Facets Mindfulness Questionnaire (FFMQ), Self-Other Four Immeasurables (SOFI) and the MINDSENS Composite Index were administered. ANCOVAs and linear regression models were used to assess pre-post changes and mediation/moderation effects. Results: Compared to controls, retreatants showed increases in non-attachment, observing, MINDSENS, positive-affect, balance-affect, and cooperativeness; and decreases in describing, negative-others, reward-dependence and self-directedness. Non-attachment had a mediating role in decentring, acting aware, non-reactivity, negative-affect, balance-affect and self-directedness; and a moderating role in describing and positive others, with both mediating and moderating effects on satisfaction with life. Conclusions: A 1-month Vipassana meditation retreat seems to yield improvements in mindfulness, well-being, and personality, even in experienced meditators. Non-attachment might

Somatic Experiencing ® (SE™) is a resiliency-based treatment for autonomic nervous systems dysregulation syndromes, such as posttraumatic stress disorder, anxiety, depression, and physical syndromes like chronic pain, migraines, and fibromyalgia. "Transgender/gender non-conforming/gender variant" describes people whose gender identity/expression is different, at least part of the time, from the sex assigned at birth. Research indicates transgender individuals have a higher incidence of depression, anxiety, victimization, and discrimination. SE™ tools may support transgender/gender non-conforming individuals to increase resilience in the face of discrimination and social injustice. This study is a pretest posttest within group ( N = 7) pilot study assessing the impact of a 10 session SE™ based group treatment on depression (PHQ-9), anxiety (GAD-7), somatic symptoms (PHQ-15), quality of life (QoL) (WHOQoL-BREF), and coping with discrimination (CDS) for a cohort of seven individuals identifying as transgender/gender non-conforming. Materials were created in collaboration with members of the LGBTQIA community. Care was taken to be inclusive of gender non-conforming identities and culturally responsive in design. Participants described their gender identities as: non-binary, female to male, male to female, and gender fluid. Participants had significant increase in psychological QoL (psychological well-being) (WHOQoL-BREF) p = 0.004, SD = 2.31, with a modest effect size of d = 0.71. Some likely impacts of historical effect discussed. No other clinical or QoL outcomes were statistically significant. However, one outlier was identified in the dataset. When this outlier was excluded there was a trend toward significant reduction in depression symptoms (PhQ-9) p = 0.097, SD = 3.31 and a modest effect size of d = 0.68; somatic symptoms (PhQ-15) p = 0.093, SD = 3.52 and a modest effect size of d = 0.72.

The role of empathy in experiencing vicarious anxiety.
Shu, Jocelyn; Hassell, Samuel; Weber, Jochen; Ochsner, Kevin N; Mobbs, Dean
2017-08-01
With depictions of others facing threats common in the media, the experience of vicarious anxiety may be prevalent in the general population. However, the phenomenon of vicarious anxiety-the experience of anxiety in response to observing others expressing anxiety-and the interpersonal mechanisms underlying it have not been fully investigated in prior research. In 4 studies, we investigate the role of empathy in experiencing vicarious anxiety, using film clips depicting target victims facing threats. In Studies 1 and 2, trait emotional empathy was associated with greater self-reported anxiety when observing target victims, and with perceiving greater anxiety to be experienced by the targets. Study 3 extended these findings by demonstrating that trait empathic concern-the tendency to feel concern and compassion for others-was associated with experiencing vicarious anxiety, whereas trait personal distress-the tendency to experience distress in stressful situations-was not. Study 4 manipulated state empathy to establish a causal relationship between empathy and experience of vicarious anxiety. Participants who took an empathic perspective when observing target victims, as compared to those who took an objective perspective using reappraisal-based strategies, reported experiencing greater anxiety, risk-aversion, and sleep disruption the following night. These results highlight the impact of one's social environment on experiencing anxiety, particularly for those who are highly empathic. In addition, these findings have implications for extending basic models of anxiety to incorporate interpersonal processes, understanding the role of empathy in social learning, and potential applications for therapeutic contexts.

The purpose of this study was to explore configurations of positive versus negative interactions between work and home (WHI) and their relation to burnout and demographic characteristics. Sample of 533 Polish workers were interviewed by means of self-administered questionnaires (SWING and MBI-GS). Demographic and work characteristics were also controlled. Cluster analysis distinguished 5 types of WHIs: positive WHI (18%), negative WHI (15.9%), no interaction (29.3%), mutual positive interactions (15.4%) and positive HWI (21.4%). The quality of WHI was associated with number of work hours and tenure at main place of employment. The effect of gender on the quality of work-home interaction was not significant. Configuration of WHIs affected the level of burnout. Again, there was no significant difference between men and women in terms of burnout and its sub-dimensions. The least burned-out were people from positive WHI, positive HWI and mutual positive interaction groups. The most burned-out were people who experienced negative WHI the most often. In this group, predominance of men working more than 10 h per day was observed. The majority of study group (71%) experienced rather integration than segmentation of both spheres. Our results suggest that segmentation is not an universal and effective strategy of coping with work and home demands - it may prevent the positive home-work spillover, which can be buffer or remedy against stress or burnout. We consider cluster analysis the appropriate method in research on relation to work-family balance issue, which may be useful in unraveling relationships between this phenomenon and attitudes and behaviors.

Meaning making in cancer survivors: a focus group study.
Directory of Open Access Journals (Sweden)
Nadia van der Spek
Full Text Available BACKGROUND: Confrontation with a life-threatening disease like cancer can evoke existential distress, which can trigger a search for meaning in people after having survived this disease. METHODS: In an effort to gain more insight in the meaning making process, we conducted four focus groups with 23 cancer survivors on this topic. Participants responded to questions about experienced meaning making, perceived changes in meaning making after cancer and the perceived need for help in this area. RESULTS: Most frequently mentioned meaning making themes were relationships and experiences. We found that, in general, cancer survivors experienced enhanced meaning after cancer through relationships, experiences, resilience, goal-orientation and leaving a legacy. Some participants, however, also said to have (also experienced a loss of meaning in their lives through experiences, social roles, relationships and uncertainties about the future. CONCLUSIONS: The results indicated that there is a group of cancer survivors that has succeeded in meaning making efforts, and experienced sometimes even more meaning in life than before diagnosis, while there is also a considerable group of survivors that struggled with meaning making and has an unmet need for help with that. The results of this study contribute to develop a meaning centered intervention for cancer survivors.

The goal of the present study was to explore how anger reduction via a single session of meditation might be measured using psychophysiological methodologies. To achieve this, 15 novice meditators (Experiment 1) and 12 practiced meditators (Experiment 2) completed autobiographical anger inductions prior to, and following, meditation training while respiration rate, heart rate, and blood pressure were measured. Participants also reported subjective anger via a visual analog scale. At both stages, the experienced meditators' physiological reaction to the anger induction reflected that of relaxation: slowed breathing and heart rate and decreased blood pressure. Naïve meditators exhibited physiological reactions that were consistent with anger during the pre-meditation stage, while after meditation training and a second anger induction they elicited physiological evidence of relaxation. The current results examining meditation training show that the naïve group's physiological measures mimicked those of the experienced group following a single session of meditation training.

High levels of experienced job autonomy are found to be beneficial for healthcare professionals and for the relationship with their patients. The aim of this study was to assess how maternity care professionals in the Netherlands perceive their job autonomy in the Dutch maternity care system and whether they expect a new system of integrated maternity care to affect their experienced job autonomy. A cross-sectional survey. The Leiden Quality of Work Life Questionnaire was used to assess experienced job autonomy among maternity care professionals. Data were collected in the Netherlands in 2015. 799 professionals participated of whom 362 were primary care midwives, 240 obstetricians, 93 clinical midwives and 104 obstetric nurses. The mean score for experienced job autonomy was highest for primary care midwives, followed by obstetricians, clinical midwives and obstetric nurses. Primary care midwives scored highest in expecting to lose their job autonomy in an integrated care system. There are significant differences in experienced job autonomy between maternity care professionals. When changing the maternity care system it will be a challenge to maintain a high level of experienced job autonomy for professionals. A decrease in job autonomy could lead to a reduction in job related wellbeing and in satisfaction with care among pregnant women. Copyright © 2017. Published by Elsevier Ltd.

Emotion experienced during encoding enhances odor retrieval cue effectiveness.
Herz, R S
1997-01-01
Emotional potentiation may be a key variable in the formation of odor-associated memory. Two experiments were conducted in which a distinctive ambient odor was present or absent during encoding and retrieval sessions and subjects were in an anxious or neutral mood during encoding. Subjects' mood at retrieval was not manipulated. The laboratory mood induction used in Experiment 1 suggested that anxiety might increase the effectiveness of an odor retrieval cue. This trend was confirmed in Experiment 2 by capturing a naturally stressful situation. Subjects who had an ambient odor cue available and were in a preexam state during encoding recalled more words than subjects in any other group. These data are evidence that heightened emotion experienced during encoding with an ambient odor can enhance the effectiveness of an odor as a cue to memory.

Groups, matrices, and vector spaces a group theoretic approach to linear algebra
Carrell, James B
2017-01-01
This unique text provides a geometric approach to group theory and linear algebra, bringing to light the interesting ways in which these subjects interact. Requiring few prerequisites beyond understanding the notion of a proof, the text aims to give students a strong foundation in both geometry and algebra. Starting with preliminaries (relations, elementary combinatorics, and induction), the book then proceeds to the core topics: the elements of the theory of groups and fields (Lagrange's Theorem, cosets, the complex numbers and the prime fields), matrix theory and matrix groups, determinants, vector spaces, linear mappings, eigentheory and diagonalization, Jordan decomposition and normal form, normal matrices, and quadratic forms. The final two chapters consist of a more intensive look at group theory, emphasizing orbit stabilizer methods, and an introduction to linear algebraic groups, which enriches the notion of a matrix group. Applications involving symm etry groups, determinants, linear coding theory ...

Normal-dispersion microresonator Kerr frequency combs
Directory of Open Access Journals (Sweden)
Xue Xiaoxiao
2016-06-01
Full Text Available Optical microresonator-based Kerr frequency comb generation has developed into a hot research area in the past decade. Microresonator combs are promising for portable applications due to their potential for chip-level integration and low power consumption. According to the group velocity dispersion of the microresonator employed, research in this field may be classified into two categories: the anomalous dispersion regime and the normal dispersion regime. In this paper, we discuss the physics of Kerr comb generation in the normal dispersion regime and review recent experimental advances. The potential advantages and future directions of normal dispersion combs are also discussed.

A cochlear implant is a device that helps hearing-impaired children by transmitting sound signals to the brain and helping them improve their speech, language, and social interaction. Although various studies have investigated the different aspects of speech perception and language acquisition in cochlear-implanted children, little is known about their social skills, particularly Persian-speaking cochlear-implanted children. Considering the growing number of cochlear implants being performed in Iran and the increasing importance of developing near-normal social skills as one of the ultimate goals of cochlear implantation, this study was performed to compare the social interaction between Iranian cochlear-implanted children who have undergone rehabilitation (auditory verbal therapy) after surgery and normal-hearing children. This descriptive-analytical study compared the social interaction level of 30 children with normal hearing and 30 with cochlear implants who were conveniently selected. The Raven test was administered to the both groups to ensure normal intelligence quotient. The social interaction status of both groups was evaluated using the Vineland Adaptive Behavior Scale, and statistical analysis was performed using Statistical Package for Social Sciences (SPSS) version 21. After controlling age as a covariate variable, no significant difference was observed between the social interaction scores of both the groups (p > 0.05). In addition, social interaction had no correlation with sex in either group. Cochlear implantation followed by auditory verbal rehabilitation helps children with sensorineural hearing loss to have normal social interactions, regardless of their sex.

The Asian population in Britain has grown, representing the second largest ethnic group; Bangladeshi, Pakistani, and Indian nationalities are prevalent (Jivraj, 2012 ; Office for National Statistics, 2013 ). Yet, we know relatively little about the nature and extent of their substance use. Jayakody et al. ( 2006 ) argue ethnic minority groups may be influenced by the norms and values of the dominant culture. Given recreational drug use has undergone a process of normalization in Britain (Aldridge et al., 2011 ; Parker et al., 1998 , 2002 ), we explore the degree to which this is occurring in a Bangladeshi and Pakistani community of Muslim faith in Northern England; a group typically assumed to reject substance use because of robust religious and cultural values. To examine the extent, frequency, and nature of substance use, and associated attitudes. A cross-sectional study collecting qualitative data from a sample (N = 43) of adolescents accessing a drug service and a range of professionals working with them during 2014. We also present analyses of routinely collected quantitative client data. Adolescent interviewees reported extensive personal experience smoking skunk cannabis, and professionals working in the community confirmed many young Asians smoked it. Its consumption appeared to be accommodated into the daily lives of young people and the supply of it also showed signs of acceptance. Skunk cannabis may be undergoing a process of normalization within some Asian communities in Britain. Our study has significant implications for the normalization thesis, finding evidence for normalization within a subpopulation that is typically perceived to resist this trend.

Patient affect experiencing following therapist interventions in short-term dynamic psychotherapy.
Town, Joel M; Hardy, Gillian E; McCullough, Leigh; Stride, Chris
2012-01-01
The aim of this research was to examine the relationship between therapist interventions and patient affect responses in Short-Term Dynamic Psychotherapy (STDP). The Affect Experiencing subscale from the Achievement of Therapeutic Objectives Scale (ATOS) was adapted to measure individual immediate affect experiencing (I-AES) responses in relation to therapist interventions coded within the preceding speaking turn, using the Psychotherapy Interaction Coding (PIC) system. A hierarchical linear modelling procedure was used to assess the change in affect experiencing and the relationship between affect experiencing and therapist interventions within and across segments of therapy. Process data was taken from six STDP cases; in total 24 hours of video-taped sessions were examined. Therapist interventions were found to account for a statistically significant amount of variance in immediate affect experiencing. Higher levels of immediate affect experiencing followed the therapist's use of Confrontation, Clarification and Support compared to Questions, Self-disclosure and Information interventions. Therapist Confrontation interventions that attempted to direct pressure towards either the visceral experience of affect or a patient's defences against feelings led to the highest levels of immediate affect experiencing. The type of therapist intervention accounts for a small but significant amount of the variation observed in a patient's immediate emotional arousal. Empirical findings support clinical theory in STDP that suggests strategic verbal responses promote the achievement of this specific therapeutic objective.

The significance of early post-exercise ST segment normalization.
Chow, Rudy; Fordyce, Christopher B; Gao, Min; Chan, Sammy; Gin, Kenneth; Bennett, Matthew
2015-01-01
The persistence of ST segment depression in recovery signifies a strongly positive exercise treadmill test (ETT). However, it is unclear if early recovery of ST segments portends a similar prognosis. We sought to determine if persistence of ST depression into recovery correlates with ischemic burden based on myocardial perfusion imaging (MPI). This was a retrospective analysis of 853 consecutive patients referred for exercise MPI at a tertiary academic center over a 24-month period. Patients were stratified into three groups based on the results of the ETT: normal (negative ETT), persistence (positive ETT with >1mm ST segment depression at 1minute in recovery) and early normalization (positive ETT with normalization, while 105 patients met criteria for persistence. The persistence group had a significantly greater SSS (8.48±7.77) than both the early normalization (4.34±4.98, pnormal (4.47±5.31, pnormalization and normal groups were not statistically different and met the prespecified non-inferiority margin (mean difference 0.12, -0.66=lower 95% CI, pnormal and 7.4% of early normalization groups. Among patients with an electrically positive ETT, recovery of ST segment depression within 1minute was associated with a lower SSS than patients with persistence of ST depression beyond 1minute. Furthermore, early ST segment recovery conferred a similar SSS to patients with a negative ETT. These results suggest that among patients evaluated for chest pain with a positive ETT, early recovery of the ST segment during recovery is associated with a significantly less ischemic burden on subsequent MPI and thus may represent a false positive finding in exercise treadmill testing.

Especial Skills in Experienced Archers.
Nabavinik, Mahdi; Abaszadeh, Ali; Mehranmanesh, Mehrab; Rosenbaum, David A
2017-09-05
Especial skills are skills that are distinctive by virtue of massive practice within the narrow contexts in which they are expressed. In the first demonstration of especial skills, Keetch, Schmidt, Lee, and Young (2005) showed that experienced basketball players are better at shooting baskets from the foul line, where they had massive amounts of practice, than would expected from their success at other locations closer to or farther from the basket. Similar results were obtained for baseball throwing. The authors asked whether especial skills hold in archery, a sport requiring less movement. If the emergence of especial skills depends on large-scale movement, one would expect archery to escape so-called especialism. But if the emergence of especial skills reflects a more general tendency for highly specific learning, experienced archers should show especial skills. The authors obtained evidence consistent with the latter prediction. The expert archers did much better at their most highly practiced distance than would be expected by looking at the overall function relating shooting score to distance. We offer a mathematical model to account for this result. The findings attest to the generality of the especial skills phenomenon.

A study of disability among the indigenous Sami people in Norway presented a number of ethical and methodological challenges rarely addressed in the literature. The main study was designed to examine and understand the everyday life, transitions between life stages and democratic participation of Norwegian Sami people experiencing disability. Hence, the purpose of this article is to increase the understanding of possible ethical and methodological issues in research within this field. The article describes and discusses ethical and methodological issues that arose when conducting our study and identifies some strategies for addressing issues like these. The ethical and methodological issues addressed in the article are based on a qualitative study among indigenous Norwegian Sami people experiencing disability. The data in this study were collected through 31 semi-structured in-depth interviews with altogether 24 Sami people experiencing disability and 13 next of kin of Sami people experiencing disability (8 mothers, 2 fathers, 2 sister and 1 guardian). The researchers identified 4 main areas of ethical and methodological issues. We present these issues chronologically as they emerged in the research process: 1) concept of knowledge when designing the study, 2) gaining access, 3) data collection and 4) analysis and accountability. The knowledge generated from this study has the potential to benefit future health research, specifically of Norwegian Sami people experiencing disability, as well as health research concerning indigenous people in general, providing scientific-based insight into important ethical and methodological issues in research with indigenous people experiencing disability.

Transition from normal to ballistic diffusion in a one-dimensional impact system
Livorati, André L. P.; Kroetz, Tiago; Dettmann, Carl P.; Caldas, Iberê L.; Leonel, Edson D.
2018-03-01
We characterize a transition from normal to ballistic diffusion in a bouncing ball dynamics. The system is composed of a particle, or an ensemble of noninteracting particles, experiencing elastic collisions with a heavy and periodically moving wall under the influence of a constant gravitational field. The dynamics lead to a mixed phase space where chaotic orbits have a free path to move along the velocity axis, presenting a normal diffusion behavior. Depending on the control parameter, one can observe the presence of featured resonances, known as accelerator modes, that lead to a ballistic growth of velocity. Through statistical and numerical analysis of the velocity of the particle, we are able to characterize a transition between the two regimes, where transport properties were used to characterize the scenario of the ballistic regime. Also, in an analysis of the probability of an orbit to reach an accelerator mode as a function of the velocity, we observe a competition between the normal and ballistic transport in the midrange velocity.

The serum concentration of carcinoembryonic antigen (CEA) was determined by radioimmunoassay in 95 normal individuals (41 women and 54 men), 20 to 65 years of age. Depending on sex and age, the tested individuals were divided in four groups: gr. I - 27 women, 20 to 40 years of age; gr. II - 14 women, 4O to 65 years of age; gr. III -35 men, 20 to 40 years of age, and group IV - 19 men, 40 to 65 years of age. The following mean serum CEA levels were obtained in normal individuals: Group I -6.8 +- 1.07 ng/ml; group II - 9.71 +- 1.46 ng/ml; group III - 4.9 +- 0.73 ng/ml; group IV - 7.5 +- 1.5 ng/ml. The CEA levels in the serum of normal individuals varied with age and sex, but the differences were statistically insignificant (p> 0.10). Normal values fo serum CEA concentrations in normal individuals were determined. These values are meant to be used for comparison with serum CEA values in patients with malignant diseases. (author)

To test the hypothesis that recreational tennis players transmit more shock impact from the racket to the elbow joint than experienced tennis players during the backhand stroke. Also, to test whether recreational tennis players used higher electromyographic (EMG) activities in common wrist extensor and flexor around epicondylar region at follow-through phase. A repeated-measure, cross-sectional study. National College of Physical Education and Sports at Taipei, Taiwan. Twenty-four male tennis players with no abnormal forearm musculoskeletal injury participated in the study. According to performance level, subjects were categorized into 2 groups: experienced and recreational. Impact transmission and wrist extensor-flexor EMG for backhand acceleration, impact, and follow-through phases were recorded for each player. An independent t test with a significance level of 0.05 was used to examine mean differences of shock impact and EMG between the 2 test groups. One-way ANOVA associated with Tukey multiple comparisons was used to identify differences among different impact locations and EMG phases. Experienced athletes reduced the racket impact to the elbow joint by 89.2%, but recreational players reduced it by only 61.8%. The largest EMG differences were found in the follow-through phase (Pelbow joint and use larger wrist flexor and extensor EMG activities at follow-through phase of the backhand stroke. Follow-through control is proposed as a critical factor for reduction of shock transmission. Clinicians or trainers should instruct beginners to quickly release their grip tightness after ball-to-racket impact to reduce shock impact transmission to the wrist and elbow.

Cochlear malformations may be be subtle on imaging studies. The purpose of this study was to evaluate the angle and depth of the lateral second interscalar ridge or notch in ears without sensorineural hearing loss (normal ears) and compare them with ears that have a documented incomplete type II partition malformation. The second interscalar ridge notch angle and depth were measured on MR imaging in normal ears by a single experienced neuroradiologist. The images of normal and incomplete partition II malformation ears were then randomly mixed for 2 novice evaluators to measure both the second interscalar ridge notch angle and depth in a blinded manner. For the mixed group, interobserver agreement was calculated, normal and abnormal ear measurements were compared, and receiver operating characteristic curves were generated. The 94 normal ears had a mean second interscalar ridge angle of 80.86° ± 11.4° and depth of 0.54 ± 0.14 mm with the 98th percentile for an angle of 101° and a depth of 0.3 mm. In the mixed group, agreement between the 2 readers was excellent, with significant differences for angle and depth found between normal and incomplete partition type II ears for angle and depth on average ( P 114° and a depth of the second interscalar ridge notch of ≤0.31 mm suggest the diagnosis of incomplete partition type II malformation and scala communis. These measurements can be accurately made by novice readers. © 2018 by American Journal of Neuroradiology.

CSF volumes in the basal cistern and Sylvian fissure are increased in both idiopathic normal pressure hydrocephalus and Alzheimer disease, though the differences in these volumes in idiopathic normal pressure hydrocephalus and Alzheimer disease have not been well-described. Using CSF segmentation and volume quantification, we compared the distribution of CSF in idiopathic normal pressure hydrocephalus and Alzheimer disease. CSF volumes were extracted from T2-weighted 3D spin-echo sequences on 3T MR imaging and quantified semi-automatically. We compared the volumes and ratios of the ventricles and subarachnoid spaces after classification in 30 patients diagnosed with idiopathic normal pressure hydrocephalus, 10 with concurrent idiopathic normal pressure hydrocephalus and Alzheimer disease, 18 with Alzheimer disease, and 26 control subjects 60 years of age or older. Brain to ventricle ratios at the anterior and posterior commissure levels and 3D volumetric convexity cistern to ventricle ratios were useful indices for the differential diagnosis of idiopathic normal pressure hydrocephalus or idiopathic normal pressure hydrocephalus with Alzheimer disease from Alzheimer disease, similar to the z-Evans index and callosal angle. The most distinctive characteristics of the CSF distribution in idiopathic normal pressure hydrocephalus were small convexity subarachnoid spaces and the large volume of the basal cistern and Sylvian fissure. The distribution of the subarachnoid spaces in the idiopathic normal pressure hydrocephalus with Alzheimer disease group was the most deformed among these 3 groups, though the mean ventricular volume of the idiopathic normal pressure hydrocephalus with Alzheimer disease group was intermediate between that of the idiopathic normal pressure hydrocephalus and Alzheimer disease groups. The z-axial expansion of the lateral ventricle and compression of the brain just above the ventricle were the common findings in the parameters for differentiating

Full Text Available The purpose of this study is to establish a protocol of retention-enema experiments and evaluate the antihypertensive effect and the safety of Gwakhyangjeonggi-san retention enema. Normal and spontaneously hypertensive rats (SHRs were divided into treatment and control groups, respectively. We applied the Gwakhyangjeonggi-san extract by decoction and 0.9% NaCl in each group, estimated the blood pressure and body weight, and performed HPLC analysis. ALT, AST, BUN, and creatinine were examined. The systolic blood pressure within each group in normal rats differed significantly in time effect, and so did the diastolic blood pressure in the treatment group of normal rats. The systolic, diastolic, and mean blood pressure showed significant differences in group effect in the treatment group of the SHRs. The time effect of the body weight in both groups of normal rats differed significantly, so did group × time and time effects in both groups of SHRs. AST, ALT, BUN, and creatinine showed no significant difference between groups. We concluded that the Gwakhyangjeonggi-san retention enema has a hypotensive effect in normal rats within the regular range of blood pressure, but an antihypertensive effect in SHRs. Also, the intervention is safe and does not affect the liver and kidney functions in normal rats.

Given the significant health effects of domestic violence against women, the present study was conducted in 2016, in Tehran, Iran in order to compare the socioeconomic status, perceived social support and mental status in women of reproductive age experiencing and not experiencing domestic violence. This descriptive-analytical cross-sectional study was conducted on 500 women. The data collection tools used included questionnaires: demographic information, Socioeconomic, Beck's Depression, Spielberger's Anxiety, Cohen's Perceived Stress, Sarason's Perceived Social Support and WHO's Domestic Violence Inventory. The results showed that 43.2% of women said they had experienced at least one case of domestic violence, among which 16.4%, 15% and 36.6% of women had experienced physical, sexual and emotional-verbal types of violence, respectively. The mean age (p less than 0.001) and educational level (p=0/018) of violated women and their spouses (p less than 0.001) were lower than those of non-violated women. Furthermore, violated women experienced lower socioeconomic status (p less than 0.05), higher perceived stress (p less than 0.008), higher depression (p less than 0.001), and higher overt anxiety (0.002. They also perceived lower levels of social support (p less than 0.001). The issue of domestic violence was rather prevalent in the participants of the present study, particularly the younger, less educated and more socioeconomically deprived communities and families.

This study compared rCBF pattern in normal adult and normal children using statistical parametric mapping (SPM). The purpose of this study was to determine distribution pattern not seen visual analysis in both groups. Tc-99m ECD brain SPECT was performed in 12 normal adults (M:F=11:1, average age 35 year old) and 6 normal control children (M:F=4:2, 10.5{+-}3.1y) who visited psychiatry clinic to evaluate ADHD. Their brain SPECT revealed normal rCBF pattern in visual analysis and they were diagnosed clinically normal. Using SPM method, we compared normal adult group's SPECT images with those of 6 normal children subjects and measured the extent of the area with significant hypoperfusion and hyperperfusion (p<0.001, extent threshold=16). The areas of both angnlar gyrus, both postcentral gyrus, both superior frontal gyrus, and both superior parietal lobe showed significant hyperperfusion in normal adult group compared with normal children group. The areas of left amygdala gyrus, brain stem, both cerebellum, left globus pallidus, both hippocampal formations, both parahippocampal gyrus, both thalamus, both uncus, both lateral and medial occipitotemporal gyrus revealed significantly hyperperfusion in the children. These results demonstrated that SPM can say more precise anatomical area difference not seen visual analysis.

Ayahuasca, a South American psychotropic plant tea containing the psychedelic 5-HT2A receptor agonist N,N-dimethyltryptamine, has been shown to increase regional cerebral blood flow in prefrontal brain regions after acute administration to humans. Despite interactions at this level, neuropsychological studies have not found cognitive deficits in abstinent long-term users. Here, we wished to investigate the effects of acute ayahuasca intake on neuropsychological performance, specifically on working memory and executive function. Twenty-four ayahuasca users (11 long-term experienced users and 13 occasional users) were assessed in their habitual setting using the Stroop, Sternberg, and Tower of London tasks prior to and following ayahuasca intake. Errors in the Sternberg task increased, whereas reaction times in the Stroop task decreased and accuracy was maintained for the whole sample following ayahuasca intake. Interestingly, results in the Tower of London showed significantly increased execution and resolution times and number of movements for the occasional but not the experienced users. Additionally, a correlation analysis including all subjects showed that impaired performance in the Tower of London was inversely correlated with lifetime ayahuasca use. Acute ayahuasca administration impaired working memory but decreased stimulus-response interference. Interestingly, detrimental effects on higher cognition were only observed in the less experienced group. Rather than leading to increased impairment, greater prior exposure to ayahuasca was associated with reduced incapacitation. Compensatory or neuromodulatory effects associated with long-term ayahuasca intake could underlie preserved executive function in experienced users.

Full Text Available Role players within the context of managed healthcare in Gauteng experience problems in the delivery of healthcare, which negatively affect their working relationships. This in turn, affects the quality of care provided to patients. The purpose of this study is to explore and describe the problem experienced by different role players within the context of managed healthcare in Gauteng, as well as the suggested solutions to counteract these problems. These results will be utilised as the basis of a conceptual framework to formulate a strategy to enhance the working relationships amongst these role players. The strategy will not be discussed in this article as the focus is on the problems experienced by the role players in the delivery of healthcare, as well as suggested solutions in the counteraction thereof. A qualitative, exploratory, descriptive and contextual study was followed to explore and describe the problems, as well as the suggested solutions to counteract these problems. Focus group interviews were conducted to collect data from three private hospitals, three managed care organisations and four general medical practitioners in Gauteng. The participants were purposively and conveniently selected. Content analysis as described by Tesch (1990 was followed to analyse the data. The main problems experienced were related to inadequate communication, inadequate staff competence, cost saving versus quality care, procedural complexity, perceived loss of power by doctors and patients and the system of accounts payment. The suggested solutions focused mainly on empowerment and standardisation of procedures. It is recommended that replication studies of this nature be conducted in other provinces and that ethical standards are formulated within the managed healthcare context.

Normal {sup 51}Cr-ethylenediaminetetraacetic acid (EDTA) clearance values as a function of age were published a number of years ago. These values were based on data from children with a normal left to right ratio and a normal appearance on DMSA scintigraphy, despite the presence of an acute renal infection. At that time, the authors were unaware that hyperfiltration is a common phenomenon in patients with acute renal infection and that their normal values could have been significantly overestimated. The present work therefore aimed to re-appraise these normal values. In a first step, in order to verify the previous results, the same type of population was selected, namely patients with present or past urinary tract infection but normal images and a normal left to right ratio on DMSA scintigraphy. In a second step, the selection was based on patients who had had no recent urinary tract infection. In both series, a single blood sample method was used for the evaluation of {sup 51}Cr-EDTA clearance. In the first group of patients, the results obtained were almost identical to those previously published. In the second group of patients, the results were significantly lower: after 2 years of age, the mean GFR value was 104 ml/min/1.73 m{sup 2} (10th and 90th percentiles 81 and 135 ml/min/1.73 m{sup 2}, respectively), compared with 117 ml/min/1.73 m{sup 2} in the first group. The data of the second group are probably more representative of the true normal GFR values and can be applied to the entire paediatric population. (orig.)

A summary of results obtained with the Einstein Observatory is presented. There are two general categories of normal galaxy investigation being pursued - detailed studies of nearby galaxies where individual sources can be detected and possibly correlated with galactic morphology, and shorter observations of many more distant objects to determine the total luminosity distribution of normal galaxies. The principal examples of the first type are the CFA study of M31 and the Columbia study of the Large Magellanic Cloud. The Columbia normal galaxy survey is the principal example of the second type, although there also are smaller CFA programs concentrating on early galaxies and peculiar galaxies, and MIT has observed some members of the local group.

Kwon, Soyang; Mohammad, Jamal; Samuel, Isaac
2011-01-01
To compare physical activity patterns between morbidly obese and normal-weight women. Daily physical activity of 18 morbidly obese and 7 normal-weight women aged 30-58 years was measured for 2 days using the Intelligent Device for Energy Expenditure and Activity (IDEEA) device. The obese group spent about 2 hr/day less standing and 30 min/day less walking than did the normal-weight group. Time spent standing (standing time) was positively associated with time spent walking (walking time). Age- and walking time-adjusted standing time did not differ according to weight status. Promoting standing may be a strategy to increase walking.

Márcia Mendes Menezes
Full Text Available ABSTRACT The current study aimed to identify and analyze the prevalence of ethical conflicts experienced by medical students. This study is a cross-sectional and analytical research that was conducted in a public school in the state of Minas Gerais, Brazil. The instrument used for the data collection was a self-administered questionnaire. The data collected were presented in absolute and percentage values. For the analytical statistical treatment of the data, the level of significance was considered p <0.05. The outcome variables were: Experiences of ethical conflicts in interpersonal relations within the medical course and Ethical conduct in health care. The identification of the prevalence of ethical conflicts in the undergraduate program adopted the perspective of different interpersonal relations (academic-teaching, academic-academic, academic-employee, academic-patient, teacher-teacher, teacher-patient, teacher-employee and employee-patient. (Importance of identifying themselves to the health services user and requesting consent to perform the physical examination, assistance without the supervision of the teacher, issuance of health documents without the signature of the professional responsible and use of social networks to share data Of patient. It was verified the association of the outcome variables with sex, year of graduation and course evaluation. A total of 281 undergraduate students enrolled in all undergraduate courses in Medicine of both sexes, with a predominance of female (52.7%. The students reported having experienced conflicting situations in interpersonal relations with teachers (59.6%, provided assistance without proper supervision of a teacher (62.6%, reported having issued health documents without the accompaniment of teachers (18, 5%. The highest frequency was observed among those enrolled in the most advanced years of the undergraduate program (p <0.05. The use of social networks for the purpose of sharing patient

Hypoxia training: symptom replication in experienced military aircrew.
Johnston, Ben J; Iremonger, Gareth S; Hunt, Sheena; Beattie, Elizabeth
2012-10-01
Military aircrew are trained to recognize the signs and symptoms of hypoxia in a safe environment using a variety of methods to simulate altitude. In order to investigate the effectiveness of hypoxia training, this study compared the recall of hypoxia symptoms in military aircrew between two consecutive hypobaric chamber hypoxia training sessions conducted, on average, 4.5 yr apart. Previously trained subjects completed a questionnaire immediately before and after they underwent refresher hypoxia training and recorded the occurrence, order, and severity of symptoms experienced. Responses from refresher training were compared with their recall of symptoms experienced during previous training. There was no difference in the recall of most hypoxia symptoms between training sessions. Slurred speech was recalled more frequently from previous training compared to refresher training (14 vs. 4 subjects), whereas hot/cold flushes were recalled less frequently from previous training compared to refresher training (5 vs. 17 subjects). There was a statistically significant difference in overall hypoxia score (10.3 vs. 8.3), suggesting that from memory subjects may underestimate the level of hypoxia experienced in previous training. A high level of similarity between the recall of previously experienced hypoxia symptoms and recent experience supports the effectiveness of hypoxia training. These results replicate the finding of a 'hypoxia signature' reported by a previous study. Small differences in the recall of some symptoms and in overall hypoxia score highlight the importance of drawing attention to the more subtle symptoms of early hypoxia, and of using training techniques which optimize aircrew recall.

Since the mid-1970s, cross-species translational studies of prepulse inhibition (PPI) have increased at an astounding pace as the value of this neurobiologically informative measure has been optimized. PPI occurs when a relatively weak sensory event (the prepulse) is presented 30-500 ms before a strong startle-inducing stimulus, and reduces the magnitude of the startle response. In humans, PPI occurs in a robust, predictable manner when the prepulse and startling stimuli occur in either the same or different modalities (acoustic, visual, or cutaneous). This review covers three areas of interest in human PPI studies. First, we review the normal influences on PPI related to the underlying construct of sensori- (prepulse) motor (startle reflex) gating. Second, we review PPI studies in psychopathological disorders that form a family of gating disorders. Third, we review the relatively limited but interesting and rapidly expanding literature on pharmacological influences on PPI in humans. All studies identified by a computerized literature search that addressed the three topics of this review were compiled and evaluated. The principal studies were summarized in appropriate tables. The major influences on PPI as a measure of sensorimotor gating can be grouped into 11 domains. Most of these domains are similar across species, supporting the value of PPI studies in translational comparisons across species. The most prominent literature describing deficits in PPI in psychiatrically defined groups features schizophrenia-spectrum patients and their clinically unaffected relatives. These findings support the use of PPI as an endophenotype in genetic studies. Additional groups of psychopathologically disordered patients with neuropathology involving cortico-striato-pallido-pontine circuits exhibit poor gating of motor, sensory, or cognitive information and corresponding PPI deficits. These groups include patients with obsessive compulsive disorder, Tourette's syndrome

Potentially, radiation detectors at ports of entry could be mounted on container gantry crane spreaders to monitor cargo containers entering and leaving the country. These detectors would have to withstand the extreme physical environment experienced by these spreaders during normal operations. Physical shock data from the gable ends of a spreader were recorded during the loading and unloading of a cargo ship with two Lansmont SAVER 9X30 units (with padding) and two PCB Piezotronics model 340A50 accelerometers (hard mounted). Physical shocks in the form of rapid acceleration were observed in all accelerometer units with values ranging from 0.20 g’s to 199.99 g’s. The majority of the shocks for all the Lansmont and PCB accelerometers were below 50 g’s. The Lansmont recorded mean shocks of 21.83 ± 13.62 g’s and 24.78 ± 11.49 g’s while the PCB accelerometers experienced mean shocks of 34.39 ± 25.51 g’s and 41.77 ± 22.68 g’s for the landside and waterside units, respectively. Encased detector units with external padding should be designed to withstand at least 200 g’s of acceleration without padding and typical shocks of 30 g’s with padding for mounting on a spreader.

Full Text Available We analyze the normalization factors (k′-factors used to scale secondary observers to the Royal Greenwich Observatory (RGO reference series of the Hoyt & Schatten (1998a, 1998b group sunspot number (GSN. A time series of these k′-factors exhibits an anomaly from 1841 to 1920, viz., the average k′-factor for all observers who began reporting groups from 1841 to 1883 is 1.075 vs. 1.431 for those who began from 1884 to 1920, with a progressive rise, on average, during the latter period. The 1883–1884 break between the two subintervals occurs precisely at the point where Hoyt and Schatten began to use a complex daisy-chaining method to scale observers to RGO. The 1841–1920 anomaly implies, implausibly, that the average sunspot observer who began from 1841 to 1883 was nearly as proficient at counting groups as mid-20th century RGO (for which k′ = 1.0 by definition while observers beginning during the 1884–1920 period regressed in group counting capability relative to those from the earlier interval. Instead, as shown elsewhere and substantiated here, RGO group counts increased relative to those of other long-term observers from 1874 to ~1915. This apparent inhomogeneity in the RGO group count series is primarily responsible for the increase in k′-factors from 1884 to 1920 and the suppression, by 44% on average, of the Hoyt and Schatten GSN relative to the original Wolf sunspot number (WSN before ~1885. Correcting for the early “learning curve” in the RGO reference series and minimizing the use of daisy-chaining rectifies the anomalous behavior of the k′-factor series. The resultant GSN time series (designated GSN* is in reasonable agreement with the revised WSN (SN*; Clette & Lefèvre 2016 and the backbone-based group sunspot number (RGS; Svalgaard & Schatten 2016 but significantly higher than other recent reconstructions (Friedli, personal communication, 2016; Lockwood et al. 2014a, 2014b; Usoskin et al. 2016a.

Full Text Available Abstract Background It has been demonstrated that endothelins (ET have significant roles in bone remodeling, metabolism and physiopathology of several bone diseases. We aimed to investigate if there was any difference between the plasma ET levels of osteoporotic patients and normals. Methods 86 patients (70 women and 16 men with a mean age of 62.6 (ranges: 51–90 years were included in this study. Patients were divided into groups of osteoporosis, osteopenia and normal regarding reported T scores of DEXA evaluation according to the suggestions of World Health Organization. According to these criteria 19, 43 and 24 were normal, osteopenic and osteoporotic respectively. Then total plasma level of ET was measured in all patients with monoclonal antibody based sandwich immunoassay (EIA method. One-way analysis of variance test was used to compare endothelin values between normals, osteopenics and osteoporotics. Results Endothelin total plasma level in patients was a mean of 98.36 ± 63.96, 100.92 ± 47.2 and 99.56 ± 56.6 pg/ml in osteoporotic, osteopenic and normal groups respectively. The difference between groups was not significant (p > 0.05. Conclusion No significant differences in plasma ET levels among three groups of study participants could be detected in this study.

Full Text Available Aim: Postprandial changes acutely alter some mechanisms in body. There are many studies showing blood oxidative status changes after food intake, and supplementation. The aim of the present study was to evaluate the effects of a standardized meal on serum total antioxidant activity (TAA in normal weight and overweight individuals. Material and Method: Fourteen normal weight and twelve overweight individuals were given a standardized meal in the morning after an overnight fast. Serum TAA, glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and triglyceride concentrations were measured at baseline, 3rd hour, and 6th hour after the meal in both groups.Results: In both normal and overweight groups, the difference between baseline and 3rd hour was significant for TAA. The TAA of the overweight group was also significantly lower than the TAA of the normal weight group at 3rd hour. However, there was no significant correlation between lipid parameters and TAA levels. Discussion: The present study shows that postprandial oxidative damage occurs more prominently in overweight individuals than in normal weight individuals. Postprandial changes acutely induce oxidative stress and impair the natural antioxidant defense mechanism. It should be noted that consuming foods with antioxidants in order to avoid various diseases and complications is useful, particularly in obese subjects.

Our engagement with time is a ubiquitous feature of our lives. We are aware of time on many scales, from the briefest flicker of change to the way our lives unfold over many years. But to what extent does this encounter reveal the true nature of temporal reality? To the extent that temporal reality is as it seems, how do we come to be aware of it? And to the extent that temporal reality is not as it seems, why does it seem that way? These are the central questions addressed by Simon Prosser in Experiencing Time. These questions take on a particular importance in philosophy for two reasons. Firstly, there is a view concerning the metaphysics of time, known as the B-theory of time, according to which the apparently dynamic quality of change, the special status of the present, and even the passage of time are all illusions. Instead, the world is a four-dimensional space-time block, lacking any of the apparent dynamic features of time. If the B-theory is correct, as the book argues, then it must be explained why ...

2008-01-01
Full Text Available This study examined differences between men and women, and between individuals experiencing rejection (Rejectees and individuals doing the rejecting (Rejectors in romantic relationship break-ups. We tested fourteen evolution-based predictions about romantic breakups using data from 193 participants; ten received support. Women more than men, for example, experienced costly sequelae such as the loss of a mate's physical protection and harmful post-breakup stalking by the ex-partner. Both men and women who were rejected, compared with those who did the rejecting, experienced more depression, loss of self-esteem, and rumination. Rejectors, on the other hand, experienced the reputational cost of being perceived by others as cruel. Exploratory data analyses revealed that women more than men reported experiencing negative emotions after a breakup, particularly feeling sad, confused, and scared. Both sexes used an array of strategies to cope with the breakup, ranging from high base-rate strategies such as discussing the breakup with friends to low base-rate strategies such as threatening suicide. The largest sex difference in coping strategies centered on the act of shopping, used by women Rejectors as well as women Rejectees, likely a strategy of appearance enhancement prior to reentering the mating market. Discussion focuses on the adaptive significance of sex differences and individual differences based on rejection status.

Adults with cerebral palsy (CP) experience multiple, functional changes as they age, including changes to communication modes and methods that enable development and maintenance of relationships, communicative participation and quality-of-life. Little is known about the nature of communication changes experienced by this group. The aim of this study was to better understand how adults with CP experience changes in their communication abilities as they age and the subsequent psychosocial impact. Twenty adults with cerebral palsy aged 40-72 years with complex communication needs (CCN) participated in a series of in-depth interviews, framing their experiences of loss and grief throughout their lives. The impact of changing communication abilities emerged as an important area of focus. Data were analysed using constructivist grounded theory methodology. Themes arising from the participants' perceptions of their communication included experiencing communication change as a loss with subsequent impact on self-concept; and how communication is integral to the process of managing losses associated with older age. Implications for speech-language pathologists working with older people with cerebral palsy and CCN include the need to understand the psychosocial impact of communication changes on social interaction, relationships and communicative participation. It is important to promote positive and meaningful communication options that maintain a coherent sense of self in addition to promoting functional communication skills and communicative participation.

This article reports on cultural influences on symptoms experienced during menopausal transition of Korean women in South Korea and Korean immigrant women in the United States. Data from independent studies of two groups of Korean women were triangulated and analyzed using descriptive and inferential statistics. The analysis indicated that Korean women in South Korea tended to report more symptoms than Korean immigrant women in the United States. Types and severity of prevalent symptoms were also found to be different between the two groups. The findings suggest that recent introduction of menopausal industries in South Korea and contextual influences on Korean women's work and immigration in the United States would be the reason for differences. Based on the findings, implications for future research are proposed.

Full Text Available Background: Lactation onset is a term of multiplying breast milk until the release of breast milk for the first time. It is also perceived by mothers as a bit hard breast, inflammed, and full of breast milk or the release of colostrum. Colostrum is the first liquid secreted by breast milk gland since the first day until the fourth day of labour. One of the factors that influences lactation onset is labour methods. Mothers who undergo sectio caesaria surgery will experience pain and prolonged effects of anesthesia compared to mothers with normal labors. Objective: To investigate the difference of colostrum releasing onset in post partum mothers with normal labors and sectio caesaria in Panembahan Senopati General Hospital, Bantul. Method: This study was quantitative with cross sectional design. The number of samples were 80 respondents selected with purposive sampling technique. Study instrument was observational sheets. Data analysis applied Mann-Whitney test. Result: The majority of respondents who had normal labors and sectio caesaria experienced different colostrum onset. In normal labors, the time of colostrum release was 1 day. In sectio caesaria labors, the time of colostrum release was 2 days. The average duration of post partum mothers with normal labors was 13,6 hours and post partum mothers with sectio caesaria was 22,6 hours. The result of Mann-Whitney test was that there was a difference between colostrum release onset of post partum mothers with normal labors and sectio caesaria with p-value of 0,001 (p<0,05. Conclusion: Colostrum onsets were different in normal labors and sectio caesaria labors.

Normal-range verbal-declarative memory in schizophrenia.
Heinrichs, R Walter; Parlar, Melissa; Pinnock, Farena
2017-10-01
Cognitive impairment is prevalent and related to functional outcome in schizophrenia, but a significant minority of the patient population overlaps with healthy controls on many performance measures, including declarative-verbal-memory tasks. In this study, we assessed the validity, clinical, and functional implications of normal-range (NR), verbal-declarative memory in schizophrenia. Performance normality was defined using normative data for 8 basic California Verbal Learning Test (CVLT-II; Delis, Kramer, Kaplan, & Ober, 2000) recall and recognition trials. Schizophrenia patients (n = 155) and healthy control participants (n = 74) were assessed for performance normality, defined as scores within 1 SD of the normative mean on all 8 trials, and assigned to normal- and below-NR memory groups. NR schizophrenia patients (n = 26) and control participants (n = 51) did not differ in general verbal ability, on a reading-based estimate of premorbid ability, across all 8 CVLT-II-score comparisons or in terms of intrusion and false-positive errors and auditory working memory. NR memory patients did not differ from memory-impaired patients (n = 129) in symptom severity, and both patient groups were significantly and similarly disabled in terms of functional status in the community. These results confirm a subpopulation of schizophrenia patients with normal, verbal-declarative-memory performance and no evidence of decline from higher premorbid ability levels. However, NR patients did not experience less severe psychopathology, nor did they show advantage in community adjustment relative to impaired patients.

To know the ethical problems experienced by oncology nurses. Descriptive and exploratory study with a qualitative approach, performed in inpatient units and in chemotherapy out-patients units that provide assistance to oncological patients in two capitals in the South region of Brazil. Eighteen nurses participated in this study, selected by snowball sampling type. For data collection, semi-structured interviews were carried out, which were recorded and transcribed, and then analyzed by thematic analysis. Two categories were established: when informing or not becomes a dilemma - showing the main difficulties related to oncological treatment information regarding health staff, health system, and infrastructure; to invest or not - dilemmas related to finitude - showing situations of dilemmas related to pain and confrontation with finitude. For the effective confrontation of the ethical problems experienced by oncology nurses to occur, it is important to invest in the training of these professionals, preparing them in an ethical and human way to act as lawyers of the patient with cancer, in a context of dilemmas related mainly to the possibility of finitude.

Life Course Typology of Adults Who Experienced Sexual Violence
Draucker, Claire Burke; Martsolf, Donna S.
2011-01-01
Two qualitative methodologies were used to develop a life course typology of individuals who had been exposed to sexual violence. Interview narratives of 121 adult women and men who participated in qualitative study of women’s and men’s responses to sexual violence provided the data. The authors combined a narrative approach (holistic-content and holistic-form analysis) to describe the life courses of the participants and a qualitative person-oriented approach (cross-case analysis) to identify meaningful sub-groups within the total sample. The six groups are: (a) life of turmoil, (b) life of struggles, (c) diminished life, (d) taking control of life, (e), finding peace in life, and (f) getting life back to normal. This work exemplifies a promising strategy for identifying sub-groups of violence-exposed individuals within a heterogeneous sample. Such a typology could aid the development of treatment approaches that consider both the substance and the structure of an individual’s life course, rather than target one specific type of violence.

We examined the influence of instructions on decision-making accuracy using video simulations of game-specific scenarios in Australian football. Skilled performers (average age of 23.4 ± 4.2 years) differing in experience (range 0 to 339 Australian Football League (AFL) matches) assumed the role of the key attacker and verbally indicated their kicking decision. Participants were randomly stratified into three groups: (1) LOOSE (n = 15)--instructed to "keep the ball away from the loose defender"; (2) TTF (n = 15) - instructed to "take the first option"; and (3) NI (control) (n = 16)--given no instructions. Gaze behaviour for a subset of participants (n = 20) was recorded. In the scenarios with an even number of attacking and defensive players, the decision-making accuracy of LOOSE was greater than TTF. This difference was most evident for lesser experienced performers, highlighting that lesser experienced performers are more affected by instructional foci than experienced performers. Gaze behaviour was not affected by instructional foci, but visual search rate was greater in scenarios of greater player number and complexity.

This paper investigates the relationship between the level of experience of managers and founders, and the likelihood of survival of their new firms. We take advantage of a comprehensive dataset covering the entire Danish labor market from 1980-2000. This is used to trace the activities of top...... ranked members of start-ups prior to their founding, and follow the fate of these firms. More specifically, we compare the survival of spin-offs from surviving parents, spin-offs from exiting parents, and other start-ups. Moreover, we investigate whether firms managed and founded by more experienced....... We also find that spin-offs from parent companies that exit are less likely to survive than either spin-offs from surviving parents or other start-ups. These findings support the theoretical arguments that organizational heritage is important for the survival of new organizations. We found no similar...

Full Text Available Background: The study was done to investigate the role of perceived heart risk factors (PHRFs in the prediction of psychological symptoms of cardiac rehabilitation (CR patients. Methods: In this cross-sectional study, 124 CR patients referred to Kermanshah Hospital of Imam Ali were assessed during April–July 2015. PHRFs scale and Depression, Anxiety, and Stress scale-21 used for data collection. The data were analyzed using linear multiple regression analysis. Results: The mean age of samples (69.4% male was 58.9 ± 9.7 years. The results of regression analysis evidenced that there is no significant relationship between any of the PHRFs with depression and anxiety (P > 0.05; however, biological (P = 0.018 and psychological (P = 0.019 risk factors significantly can predict stress. The model generally can explain 6.4% of the stress variance. Conclusion: PHRFs are included some significant predictors for experienced stress among the CR patients. Given that the biological and psychological risk factors are more effective in experienced stress by the patients, it is recommended that specialists pay more attention to the potential psychological outcomes of this group of patients.

Full Text Available Disability is understood by the World Health Organization (WHO as the outcome of the interaction between a health condition and personal and environmental factors. Comprehensive data about environmental factors is therefore essential to understand and influence disability. We aimed to identify which environmental factors have the highest impact on the performance of people with mild, moderate and severe difficulties in capacity, who are at risk of experiencing disability to different extents, using data from a pilot study of the WHO Model Disability Survey in Cambodia and random forest regression. Hindering or facilitating aspects of places to socialize in community activities, transportation and natural environment as well as use and need of personal assistance and use of medication on a regular basis were the most important environmental factors across groups. Hindering or facilitating aspects of the general environment were the most relevant in persons experiencing mild levels of difficulties in capacity, while social support, attitudes of others and use of medication on a regular basis were highly relevant for the performance of persons experiencing moderate to higher levels of difficulties in capacity. Additionally, we corroborate the high importance of the use and need of assistive devices for people with severe difficulties in capacity.

2018-01-01
We compared survival outcomes of advanced serous type epithelial ovarian cancer (EOC) patients with normal-sized ovaries and enlarged-ovarian tumors by propensity score matching analysis. The medical records of EOC patients treated at Samsung Medical Center between 2002 and 2015 were reviewed retrospectively. We investigated EOC patients with high grade serous type histology and International Federation of Gynecology and Obstetrics (FIGO) stage IIIB, IIIC, or IV who underwent primary debulking surgery (PDS) and adjuvant chemotherapy to identify patients with normal-sized ovaries. Propensity score matching was performed to compare patients with normal-sized ovaries to patients with enlarged-ovarian tumors (ratio, 1:3) according to age, FIGO stage, initial cancer antigen (CA)-125 level, and residual disease status after PDS. Of the 419 EOC patients, 48 patients had normal-sized ovary. Patients with enlarged-ovarian tumor were younger (54.0±10.3 vs. 58.4±9.2 years, p=0.005) than those with normal-sized ovary, and there was a statistically significant difference in residual disease status between the 2 groups. In total cohort with a median follow-up period of 43 months (range, 3-164 months), inferior overall survival (OS) was shown in the normal-sized ovary group (median OS, 71.2 vs. 41.4 months; p=0.003). After propensity score matching, the group with normal-sized ovary showed inferior OS compared to the group with enlarged-ovarian tumor (median OS, 72.1 vs. 41.4 months; p=0.031). In multivariate analysis for OS, normal-sized ovary remained a significant factor. Normal-sized ovary was associated with poor OS compared with the common presentation of enlarged ovaries in EOC, independent of CA-125 level or residual disease. Copyright © 2018.

The aim was to determine the magnetization transfer ratio (MTR) of normal testes, possible variations with age and to assess the feasibility of MTR in characterizing various testicular lesions. Eighty-six men were included. A three-dimensional gradient-echo MT sequence was performed, with/without an on-resonance binomial prepulse. MTR was calculated as: (SIo-SIm)/(SIo) x 100 %, where SIm and SIo refers to signal intensities with and without the saturation pulse, respectively. Subjects were classified as: group 1, 20-39 years; group 2, 40-65 years; and group 3, older than 65 years of age. Analysis of variance (ANOVA) followed by the least significant difference test was used to assess variations of MTR with age. Comparison between the MTR of normal testis, malignant and benign testicular lesions was performed using independent-samples t testing. ANOVA revealed differences of MTR between age groups (F = 7.51, P = 0.001). Significant differences between groups 1, 2 (P = 0.011) and 1, 3 (P < 0.001) were found, but not between 2, 3 (P = 0.082). The MTR (in percent) of testicular carcinomas was 55.0 ± 3.2, significantly higher than that of benign lesions (50.3 ± 4.0, P = 0.02) and of normal testes (47.4 ± 2.2, P < 0.001). MTR of normal testes decreases with age. MTR might be helpful in the diagnostic work-up of testicular lesions. (orig.)

Probiotics prophylaxis in pyelonephritis infants with normal urinary tracts.
Lee, Seung Joo; Cha, Jihae; Lee, Jung Won
2016-11-01
Pyelonephritis in infants is considered as a major factor for the formation of renal scar. To prevent recurrent pyelonephritis and renal damage, prophylaxis is extremely important. The aim of this study was to compare the effectiveness of probiotic and antibiotic prophylaxis or no-prophylaxis in infants with pyelonephritis and normal urinary tract. Altogether 191 infants, who were diagnosed with acute pyelonephritis, proven to have normal urinary tracts and followed up for 6 months on prophylaxis, were retrospectively evaluated. According to the types of prophylaxis, the infants were divided into three groups [probiotics (Lactobacillus species), antibiotics (trimethoprim/sulfamethoxazole, TMP/SMX), and noprophylaxis]. The incidence of recurrent urinary tract infection (UTI) during 6 months after the development of pyelonephritis, main causative uropathogens, and its antimicrobial sensitivities were compared. The incidence of recurrent UTI in the probiotic group was 8.2%, which was significantly lower than 20.6% in the no-prophylaxis group (P=0.035) and was not significantly different from 10.0% of the antibiotic group (P=0.532). The significant difference between the probiotic and no-prophylaxis groups was seen only in male infants (P=0.032). The main causative organism of recurrent UTI was Escherichia coli (E.coli), which was not different among the three groups (P=0.305). The resistance rate of E. coli to TMP/SMX was 100% in the antibiotic group, which was significantly higher than 25.0% in the probiotic group and 41.7% in the no-prophylaxis group (P=0.008). Probiotic prophylaxis was more effective in infants with pyelonephritis and normal urinary tract than in those with no-prophylaxis. It could be used as a natural alternative to antibiotic prophylaxis.

Half of MS pups received free access to chocolate cookies in addition to ad libitum chow from postnatal day 28 (MS+HPF. Pups were subjected to behavioral tests during young adulthood. The plasma corticosterone response to stress challenge was analyzed by radioimmunoassay.ResultsDaily caloric intake and body weight gain did not differ among the experimental groups. Ambulatory activities were decreased defecation activity and rostral grooming were increased in MS controls (fed with chow only compared with NH rats. MS controls spent less time in open arms, and more time in closed arms during the elevated plus maze test, than NH rats. Immobility duration during the forced swim test was increased in MS controls compared with NH rats. Cookie access normalized the behavioral scores of ambulatory and defecation activities and grooming, but not the scores during the elevated plus maze and swim tests in MS rats. Stress-induced corticosterone increase was blunted in MS rats fed with chow only, and cookie access normalized it.ConclusionProlonged access to HPF during adolescence and youth partly improves anxiety-related, but not depressive, symptoms in rats that experienced neonatal maternal separation, possibly in relation with improved function of the hypothalamic-pituitary-adrenal (HPA axis.

Background PubMed is the largest biomedical bibliographic information source on the Internet. PubMed has been considered one of the most important and reliable sources of up-to-date health care evidence. Previous studies examined the effects of domain expertise/knowledge on search performance using PubMed. However, very little is known about PubMed users’ knowledge of information retrieval (IR) functions and their usage in query formulation. Objective The purpose of this study was to shed light on how experienced/nonexperienced PubMed users perform their search queries by analyzing a full-day query log. Our hypotheses were that (1) experienced PubMed users who use system functions quickly retrieve relevant documents and (2) nonexperienced PubMed users who do not use them have longer search sessions than experienced users. Methods To test these hypotheses, we analyzed PubMed query log data containing nearly 3 million queries. User sessions were divided into two categories: experienced and nonexperienced. We compared experienced and nonexperienced users per number of sessions, and experienced and nonexperienced user sessions per session length, with a focus on how fast they completed their sessions. Results To test our hypotheses, we measured how successful information retrieval was (at retrieving relevant documents), represented as the decrease rates of experienced and nonexperienced users from a session length of 1 to 2, 3, 4, and 5. The decrease rate (from a session length of 1 to 2) of the experienced users was significantly larger than that of the nonexperienced groups. Conclusions Experienced PubMed users retrieve relevant documents more quickly than nonexperienced PubMed users in terms of session length. PMID:26139516

A premature birth can cause parental stress, anxiety and uncertainty. This study illustrates the long-term consequences of a preterm birth for family life. Retrospective study by questionnaire. Parents of 959 children, who were born in 1983 with a gestational age of less than 32 weeks or a birth weight of less than 1500 grams, were approached when their children turned 19 years old. We investigated various aspects of their family lives by means of a written questionnaire. We received completed questionnaires back from 595 parents (62%). The divorce rate was higher in families with a disabled child (26 vs. 14%). Working mothers (n = 257) and fathers (n = 506) experienced negative consequences in their workplace (36% and 2%, respectively). The risk factor was having a handicapped child. Financial problems were present in 11% of the families during the first year and 4% still experienced financial problems after 19 years; risk factors were a handicap, male gender and a low social-economic status (SES) of the parents. Of the respondents, 26% had observed a decrease in social activities and friends during the first year and 15% felt that family and friends provided insufficient support during this year. After 19 years, 4% of the respondents still experienced a negative influence on their social lives. Risk factors were a handicap, normal birth weight (no dysmaturity), male gender and low SES. 28% of parents expressed that during the first year having a preterm child was emotional challenging or difficult to accept. After 19 years, 3% still expressed an unfavourable effect of the preterm birth. Risk factors were handicap, dysmaturity and male gender. A premature birth has a great impact on the family, especially when the child has a handicap.

Safety of disclosing amyloid status in cognitively normal older adults.
Burns, Jeffrey M; Johnson, David K; Liebmann, Edward P; Bothwell, Rebecca J; Morris, Jill K; Vidoni, Eric D
2017-09-01
Disclosing amyloid status to cognitively normal individuals remains controversial given our lack of understanding the test's clinical significance and unknown psychological risk. We assessed the effect of amyloid status disclosure on anxiety and depression before disclosure, at disclosure, and 6 weeks and 6 months postdisclosure and test-related distress after disclosure. Clinicians disclosed amyloid status to 97 cognitively normal older adults (27 had elevated cerebral amyloid). There was no difference in depressive symptoms across groups over time. There was a significant group by time interaction in anxiety, although post hoc analyses revealed no group differences at any time point, suggesting a minimal nonsustained increase in anxiety symptoms immediately postdisclosure in the elevated group. Slight but measureable increases in test-related distress were present after disclosure and were related to greater baseline levels of anxiety and depression. Disclosing amyloid imaging results to cognitively normal adults in the clinical research setting with pre- and postdisclosure counseling has a low risk of psychological harm.

Sex differences in depressive effects of experiencing spousal bereavement.
Lee, Hyo Jung; Lee, Sang Gyu; Chun, Sung-Youn; Park, Eun-Cheol
2017-02-01
Spousal death is a significant event that becomes a turning point in an individual's life. Widowed persons experience new circumstances, which might induce depression. However, the effects of spousal death on depression can differ by sex and culture. Thus, the present study examined the association between depressive levels and experience of spousal death in Korean adults aged older than 45 years. The data were from the Korean Longitudinal Study of Aging from 2010 to 2012. The analysis used frequency analysis to compare the distribution of demographic variables between men and women, and anova to compare 10-item short-form Center for Epidemiological Studies Depression Scale scores as the dependent variable among comparison groups. We also carried out linear mixed model analysis on the association between the 10-item short-form Center for Epidemiological Studies Depression Scale and experience of spousal death. Among 5481 respondents, 2735 were men and 2741 were women. The number of men and women who experienced spousal death were 43 (1.6%) and 181 (6.6%), respectively. Men had lower depressive levels than women when they had been married (men 2.99, women 3.64). Both men and women experiencing spousal death had significantly higher 10-item short-form Center for Epidemiological Studies Depression Scale scores than married men and women (men β = 0.911, P = 0.003; women β = 0.512, P = 0.001; ref: no experience of spousal death). There was a significant association between experience of spousal death and depressive level for both men and women. We suggest that policy practitioners promote community programs that provide bereaved adults with easy access to meaningful social participation and support the minimum cost of living of the widowed.

Full Text Available Background Early motherhood constitutes a difficult challenge for girls, and the level of their performance in that role is varied. In this article, teenage motherhood as a process is considered. The objective of the research was to determine the paths by which teenage girls enter the mother role. Particular attention was paid to the nature of individual differences in the ways of experiencing and the realization of the successive steps of teenage motherhood: how the girls reacted to the fact of being a mother, what they experienced and how they behaved during pregnancy and performed child care. Participants and procedure In the research, 166 mothers who had given birth to their children between the 15th and 19th year of life were included (at the moment of giving birth to the child, the age of the mother was M = 17.22. A follower interview was used. It was directed towards recreating the course of their lives from the period preceding becoming pregnant to the period of pregnancy and looking after the child, taking into consideration the complex situations connected with life and development of the female teenagers. Results In the research, we applied the Reconstruction Strategy of the Process Transformation, setting the direction of qualitative analyses: (1 the level of single cases (case study, and (2 the level of the collection of cases (extracting groups of girls with common characteristics using the artificial intelligence algorithm C4.5. The analysis revealed the diversity and the internal structure of paths of the experience and realization of early motherhood: from negating oneself as a responsible mother to accepting the role of mother. Conclusions The final result is constituted by the model revealing the transformation of teenage motherhood and mechanisms underlying it.

Chaloupka, P; Korečko, V; Turek, J; Merglová, V
2014-01-01
The aim of this study was to compare the oral health status of women with normal pregnancies and those with high-risk pregnancies. A total of 142 women in the third trimester of pregnancy were randomly selected for this study. The pregnant women were divided into two groups: a normal pregnancy group (group F, n = 61) and a high-risk pregnancy group (group R, n = 81). The following variables were recorded for each woman: age, general health status, DMF index, CPITN index, PBI index, amounts of Streptococcus mutans in the saliva and dental treatment needs. The data obtained were analysed statistically. The Mann-Whitney test, Kruskal-Wallis test and chi square test were used, and p-values less than 0.05 were considered statistically significant. The two-sided t-test was used to compare the two cohorts. Women with high-risk pregnancies showed increased values in all measured indices and tests, but there were no statistically significant differences between the two groups in the DMF index, CPITN index and amounts of Streptococcus mutans present in the saliva. Statistically significant differences were detected between the two groups for the PBI index and dental treatment needs. In group F, the maximum PBI index value was 2.9 in group F and 3.8 in group R. Significant differences were found also in mean PBI values. Out of the entire study cohort, 94 women (66.2%) required dental treatment, including 52% (n = 32) of the women with normal pregnancies and 77% (n = 62) of the women with high-risk pregnancies. This study found that women with complications during pregnancy had severe gingivitis and needed more frequent dental treatment than women with normal pregnancies.

To quantify the osseous anatomy of the dysmorphic third sacral segment and assess its ability to accommodate internal fixation. Retrospective chart review of a trauma database. University Level 1 Trauma Center. Fifty-nine patients over the age of 18 with computed tomography scans of the pelvis separated into 2 groups: a group with normal pelvic anatomy and a group with sacral dysmorphism. The sacral osseous area was measured on computed tomography scans in the axial, coronal, and sagittal planes in normal and dysmorphic pelves. These measurements were used to determine the possibility of accommodating a transiliac transsacral screw in the third sacral segment. In the normal group, the S3 coronal transverse width averaged 7.71 mm and the S3 axial transverse width averaged 7.12 mm. The mean S3 cross-sectional area of the normal group was 55.8 mm. The dysmorphic group was found to have a mean S3 coronal transverse width of 9.49 mm, an average S3 axial transverse width of 9.14 mm, and an S3 cross-sectional area of 77.9 mm. The third sacral segment of dysmorphic sacra has a larger osseous pathway available to safely accommodate a transiliac transsacral screw when compared with normal sacra. The S3 segment of dysmorphic sacra can serve as an additional site for screw placement when treating unstable posterior pelvic ring fractures.

Game-based cognitive-behavioral therapy group model for nonoffending caregivers utilizes structured therapeutic games to assist parents following child sexual abuse. Game-based cognitive-behavioral therapy group model is a manualized group treatment approach that integrates evidence-based cognitive-behavioral therapy components with structured play therapy to teach parenting and coping skills, provide psychoeducation, and process trauma. Structured therapeutic games were designed to allow nonoffending caregivers to process their children's abuse experiences and learn skills necessary to overcome trauma in a nonthreatening, fun, and engaging manner. The implementation of these techniques allow clinicians to address a variety of psychosocial difficulties that are commonly found among nonoffending caregivers of children who have experienced sexual abuse. In addition, structured therapeutic games help caregivers develop strengths and abilities that they can use to help their children cope with abuse and trauma and facilitates the development of positive posttraumatic growth. Techniques and procedures for treatment delivery along with a description of core components and therapeutic modules are discussed. An illustrative case study is provided.

Diffusely increased skull uptake (a hot skull) is often seen in patients with bone metastases and metabolic disease. This finding is also, however, noticed in normal bone scans of aged women. To determine whether the hot skull could be considered a normal variant in elderly women and is associated to menopause, we studied 282 normal bone scans (166 women and 116 men without metabolic and hormonal disease; age range 11 to 84 yr). We divided the patients into eight age groups--ages 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-89 yrs. Measurements of skull uptake were obtained from anterior total body views using contrast-to-noise ratio (CNR). CNR for the skull was calculated using an equation. The sex dependent difference in skull uptake began to develop in the age group 30-39 yrs (p<0.05). The skull showed greater activity in women than in men for age groups from 30-39 to 80-89 yrs. In the age groups 50-59 and 60-69, the difference was particularly large (p<0.001). For women, the 50-59 yr age group had a significantly higher CNR than the 40-49 yr (p<0.01), 30-39 yr (p<0.05), and 20-29 yr age group (p<0.05). On the other hand, there was no significant difference between the 20-29 yr, 30-39 yr and 40-49 yr age groups. For men, the skull uptake was virtually unchanged with age. Our data strongly suggested that the hot skull in normal bone scan is related to menopausal estrogen deficiency. One should not necessarily regard it abnormal that elderly women suffer hot skull.

Psychophysiology of duration estimation in experienced mindfulness meditators and matched controls
Directory of Open Access Journals (Sweden)
Simone eOtten
2015-08-01
Full Text Available Recent research suggests that bodily signals and interoception are strongly related to our sense of time. Mindfulness meditators train to be aware of their body states and therefore could be more accurate at interval timing. In this study, n = 22 experienced mindfulness meditators and n = 22 matched controls performed both, an acoustic and a visual duration reproduction task of 8 s, 14s and 20s intervals, while heart rate and skin conductance were continuously assessed. In addition, participants accomplished a heart-beat perception task and two selective attention tasks. Results revealed no differences between meditators and controls with respect to performance in duration reproduction or attentional capacities. Additionally no group difference in heart beat perception scores was found. Across all subjects, correlational analyses revealed several associations between performance in the duration reproduction tasks and psychophysiological changes, the latter being also related to heart beat perception scores. Furthermore, former findings of linearly increasing cardiac periods and decreasing skin conductance levels during the auditory duration estimation task (Meissner and Wittmann, 2011 could be replicated, and these changes could also be observed during a visual duration reproduction task. In contrast to our earlier findings, the heart-beat perception test was not related with timing performance. Overall, although experienced meditators did not differ from matched controls with respect to duration reproduction and interoceptive awareness, this study adds significantly to the emerging view that time perception is related to autonomic regulation and awareness of body states.

Problems experienced by older people when opening medicine packaging.
Philbert, Daphne; Notenboom, Kim; Bouvy, Marcel L; van Geffen, Erica C G
2014-06-01
Medicine packages can cause problems in daily practice, especially among older people. This study aimed to investigate the prevalence of problems experienced by older people when opening medicine packaging and to investigate how patients manage these problems. A convenience sample of 30 community pharmacies participated in this study. They selected a systematic sample of 30 patients over 65 years old with a recent omeprazole prescription, and a questionnaire was administered by telephone for at least 10 patients per pharmacy. A total of 317 patients completed the questionnaire. They received their omeprazole in a bottle (n = 179, 56.5%), push-through blister pack (n = 102, 32.2%) or peel-off blister pack (n = 36, 11.4%). Some 28.4% of all patients experienced one or more problems with opening their omeprazole packaging; most problems occurred with peel-off blisters (n = 24, 66.7% of all respondents using peel-off blisters), followed by push-through blisters (n = 34, 33.3%) and finally bottles (n = 32, 17.9%). The risk of experiencing problems with peel-off blisters and push-through blisters was higher [relative risk 3.7 (95% confidence interval 2.5-5.5) and 1.9 (1.2-2.8), respectively] than the risk of experiencing problems with opening bottles. Two-thirds of respondents reported management strategies for their problems. Most were found for problems opening bottles (n = 24, 75%), followed by push-through blisters (n = 24, 70.6%) and peel-off blisters (n = 14, 58.3%). One in four patients over 65 experienced difficulties opening their omeprazole packaging and not all of them reported a management strategy for their problems. Manufacturers are advised to pay more attention to the user-friendliness of product packaging. In addition, it is important that pharmacy staff clearly instruct patients on how to open their medicine packaging, or assist them in choosing the most appropriate packaging. © 2013 Royal Pharmaceutical Society.

Circulating Levels of Irisin in Hypopituitary and Normal Subjects.
Directory of Open Access Journals (Sweden)
Lara Pena-Bello
Full Text Available The recently identified myokine irisin conveys some of the benefits of exercise. Hypopituitarism with adult growth hormone deficiency (HP is a situation characterized by decreased GH secretion and an altered body composition.Our aim was to study the skeletal muscle hormone irisin in HP, and compare the results with a similar group of normal subjects.Seventeen HP patients and fifty-one normal subjects of similar age and sex were studied. The diagnosis of GH deficiency was confirmed by the presence of pituitary disease and a peak GH secretion below 3 μg/L after an insulin tolerance test. The patients were adequately treated for all pituitary hormone deficits, except for GH. Fasting serum irisin was measured with an enzyme immunoassay, and HOMA-IR, QUICKI and HOMA-β were calculated.Fasting irisin levels (ng/ml were similar in normal [208.42 (168.44-249.23] and HP patients [195.13 (178.44-241.44]. In the control group there were moderate significant positive correlations between irisin and BMI, waist circumference, leptin, fasting insulin, HOMA-IR, HOMA-β, triglycerides, and cholesterol. In the control group there were moderate significant negative correlations between irisin and IGF-I and QUICKI. In the hypopituitary group there were moderate significant positive correlations between irisin and body fat and HOMA-β.We found similar irisin levels in GH deficiency hypopituitary patients when compared with normal subjects. The correlation between irisin and adiposity related factors suggests that that in the case of this clinical model, irisin is regulated by adiposity and not by GH.

Inappropriate shocks (IASs) from implantable cardioverter defibrillators (ICDs) are associated with decreased quality of life, but whether they increase healthcare utilization and treatment costs is unknown. We sought to determine the impact of IASs on subsequent healthcare utilization and treatment costs. We conducted a case-control analysis of ICD patients at a single institution from 1997 to 2010 and who had ≥12 months of post-ICD implant follow-up. Cases included all patients experiencing an IAS during the first 12 months after implantation. Eligible control patients did not receive a shock of any kind during the 12 months after implantation. Propensity scores based on 36 covariates (area under curve = 0.78) were used to match cases to controls. We compared the rate (occurrences/person year [PY]) of healthcare utilization immediately following IAS to the end of the 12-month follow-up period to the rate in the no-shock group over 12 months of follow-up. We also compared 12-month postimplant treatment (outpatient clinic, emergency room, and hospitalization) costs in both groups. A total of 76 patients experiencing ≥1 IAS during the first 12 months after implant (contributing 48 PYs) were matched to 76 no-shock patients (contributing 76 PYs). Cardiovascular (CV)-related clinic visit and hospitalization rates were increased following an IAS compared to those not receiving a shock (4.0 vs 3.3 and 0.7 vs 0.5, respectively, P = 0.02 for both). CV-related emergency room visitation (0.15 vs 0.08) rates were also numerically higher following an IAS, but did not reach statistical significance (P = 0.26). Patients experiencing an IAS accrued greater treatment costs during the 12 months postimplant compared to no-shock patients ($13,973 ± $46,345 vs $6,790 ± $19,091, P = 0.001). Recipients of IAS utilize the healthcare system more frequently following an IAS than patients not experiencing a shock. This increased utilization results in higher costs of treating IAS

Log-normality of indoor radon data in the Walloon region of Belgium
International Nuclear Information System (INIS)
Cinelli, Giorgia; Tondeur, François
2015-01-01
The deviations of the distribution of Belgian indoor radon data from the log-normal trend are examined. Simulated data are generated to provide a theoretical frame for understanding these deviations. It is shown that the 3-component structure of indoor radon (radon from subsoil, outdoor air and building materials) generates deviations in the low- and high-concentration tails, but this low-C trend can be almost completely compensated by the effect of measurement uncertainties and by possible small errors in background subtraction. The predicted low-C and high-C deviations are well observed in the Belgian data, when considering the global distribution of all data. The agreement with the log-normal model is improved when considering data organised in homogeneous geological groups. As the deviation from log-normality is often due to the low-C tail for which there is no interest, it is proposed to use the log-normal fit limited to the high-C half of the distribution. With this prescription, the vast majority of the geological groups of data are compatible with the log-normal model, the remaining deviations being mostly due to a few outliers, and rarely to a “fat tail”. With very few exceptions, the log-normal modelling of the high-concentration part of indoor radon data is expected to give reasonable results, provided that the data are organised in homogeneous geological groups. - Highlights: • Deviations of the distribution of Belgian indoor Rn data from the log-normal trend. • 3-component structure of indoor Rn: subsoil, outdoor air and building materials. • Simulated data generated to provide a theoretical frame for understanding deviations. • Data organised in homogeneous geological groups; better agreement with the log-normal

2017-10-01
The organic matrix from normal and pimpled calcified chicken eggshells were dissociated into acid-insoluble, water-insoluble, and facultative-soluble (both acid- and water-soluble) components, to understand the influence of shell matrix on eggshell qualities. A linear correlation was shown among these 3 matrix components in normal eggshells but was not observed in pimpled eggshells. In pimpled eggshells, the percentage contents of all 4 groups of matrix (the total matrix, acid-insoluble matrix, water-insoluble matrix, and facultative-soluble matrix) were significantly higher than that in normal eggshells. The amounts of both total matrix and acid-insoluble matrix in individual pimpled calcified shells were high, even though their weight was much lower than a normal eggshell. In both normal and pimpled eggshells, the calcified eggshell weight and shell thickness significantly and positively correlated with the amounts of all 4 groups of matrix in an individual calcified shell. In normal eggshells, the calcified shell thickness and shell breaking strength showed no significant correlations with the percentage contents of all 4 groups of matrix. In normal eggshells, only the shell membrane weight significantly correlated with the constituent ratios of both acid-insoluble matrix and facultative-soluble matrix in the whole matrix. In pimpled eggshells, 3 variables (calcified shell weight, shell thickness, and breaking strength) were significantly correlated with the constituent proportions of both acid-insoluble matrix and facultative-matrix. This study suggests that mechanical properties of normal eggshells may not linearly depend on the organic matrix content in the calcified eggshells and that pimpled eggshells might result by the disequilibrium enrichment of some proteins with negative effects. © 2017 Poultry Science Association Inc.

Aim: To determine whether the use of normal saline for sealing the needle track can reduce the incidence of pneumothorax and chest tube placement after computed tomography (CT)-guided lung biopsy. Materials and methods: A prospective, randomised, controlled trial enrolling 322 patients was conducted. All patients were randomly assigned to one of two groups: those in whom the needle track was not sealed with normal saline (n=161, Group A) and those who did receive normal saline (n=161, Group B). CT-guided biopsy was performed with coaxial technique. Normal saline, which ranged from 1–3 ml, was injected while the trocar needle was being withdrawn. Patient characteristics, lesion, and procedure variables were analysed as potential risk variables for occurrence of pneumothorax and chest tube placement. Results: The incidence of pneumothorax was 26.1% in Group A and 6.2% in Group B (p<0.001). Nine patients in Group A and one patient in Group B required chest tube placement (p=0.010). Using multiple logistic regression analysis, smaller lesion size, greater needle–pleural angle, longer lesion–pleural distance, presence of emphysema, and no sealing the needle track with normal saline were significantly associated with an increased risk of pneumothorax, and that the latter three factors were also associated with an increased risk of pneumothorax requiring chest tube placement. Conlusion: Normal saline for sealing the needle track significantly reduces the incidence of pneumothorax and prevents subsequent chest tube placement after CT-guided lung biopsy. - Highlights: • Normal saline is an effective sealant for use in lung biopsy. • This technique reduced the incidence of pneumothorax and chest tube placement. • This technique should be recommended for CT-guided lung biopsy.

Interactive performance and focus groups with adolescents: the power of play.
Norris, Anne E; Aroian, Karen J; Warren, Stefanie; Wirth, Jeff
2012-12-01
Conducting focus groups with adolescents can be challenging given their developmental needs, particularly with sensitive topics. These challenges include intense need for peer approval, declining social trust, short attention span, and reliance on concrete operations thinking. In this article, we describe an adaptation of interactive performance as an alternative to traditional focus group method. We used this method in a study of discrimination experienced by Muslims (ages 13-17) and of peer pressure to engage in sexual behavior experienced by Hispanic girls (ages 10-14). Recommendations for use of this method include using an interdisciplinary team, planning for large amounts of disclosure towards the end of the focus group, and considering the fit of this method to the study topic.

Clinical decision making of experienced and novice nurses.
Tabak, N; Bar-Tal, Y; Cohen-Mansfield, J
1996-10-01
Decision making is an important daily nursing activity. Given contradictory past findings concerning the ease of use cognitive schema for reaching decisions among experts and novices, we chose to examine consistency of information as a parameter that may clarify the process of decision making. Ninety-two experienced nurses and 65 nursing students rated their decisional difficulty and levels of certainty in reaching a diagnosis for two scenarios: one including consistent information and one providing information that was partly inconsistent with the given diagnosis. For the consistent information, students showed more difficulty and less certainty in the given diagnosis than the experienced nurses. The inconsistent scenario was perceived as more difficult by nurses in comparison to students. The cognitive processes responsible for these results are discussed.

2015-01-01
Full Text Available Our results showed that, at the same BMI level, Uygurs have greater WHR values, abdominal visceral fat content, and diabetes risks than Kazaks. In addition, values of HDL-C in Uygur subjects were lower than those in Kazak subjects, and values of creatinine, uric acid, diastolic blood pressure, blood glucose, and fructosamine in Uygur male subjects were lower than those in Kazak male subjects. In contrast, systolic blood pressure values in Uygur subjects were greater than those in Kazak subjects, and blood glucose values were greater in Uygur female subjects than in Kazak female subjects. Additionally, in Uygurs, visceral adipose tissue expression levels of TBX1 and TCF21 were greater in obesity group than in normal and T2DM groups and lower in T2DM group than in normal group (P<0.01. The visceral adipose tissue expression levels of APN in normal group was greater than those in obesity and T2DM groups, and visceral adipose tissue expression levels of TNF-α and MCP-1 in normal group were lower than those in obesity and T2DM groups (P<0.01. In conclusion, T2DM in Uygurs was mainly associated with not only distribution of adipose tissue in body, but also change in metabolic activity and adipocytokines secretion of adipose tissue.

Let G be a nonabelian group of order p{sup 3}, where p is a prime number. Then G is a two generated group that its commutator, centre and Frattini subgroup coincide and are of order p. Hence, the quotient group of G over its centre and also Frattini quotient group of G, both are of order p{sup 2}. However, the first mentioned quotient is isomorphic to the inner group of G, which is a normal subgroup of automorphism group of G. Whereas, Frattini quotient group of G is an abelian elementary group that can be considered as a vector space of dimension two over Z{sub p}, the field of integers modulo p. In this paper, we consider to apply these properties of G to characterize the automorphism group of G.

Full Text Available Patellar instability is a multifactorial common knee pathology that has a high recurrence rate, and the symptoms continue and ultimately predispose the patient to chondromalacia and osteoarthritis. Tibial tuberosity-trochlear groove distance (TTTG is very important in the assessment of patellofemoral joint instability. The purpose of this study was to report the normal value of TTTG in males and females in different age groups and to assess the reliability of MRI in measuring TTTG. All patients presenting with knee pain and normal examinations of the knee joint, with a normal MRI report, referring to Shahid Sadoughi hospital of Yazd, Iran, from April 2014 to September 2014, were included in the study. MR images were studied once by two radiologists and for the second time by one radiologist. Mean value of TTTG was reported for males and females and in three age groups. Intra- and inter-observer reliability was calculated. A total of 98 patients were eligible to evaluate during 6 months (68 male and 30 female. Mean TTTG was 10.9±2.5 mm in total, which was 10.8±2.8 mm and 11.3±2.3 mm in males and females, respectively (P>0.05. Mean TTTG in males ≤30 years, 30-50 years and, ≥51-year-old were 10.8±2.6 mm, 10.8±2.7 mm, and 10.8±2.6 mm, respectively; that was 12.1±3.4 mm, 11.4±1.9 mm, and 10.5±1.7 mm in females ≤30 years, 31-50 years and, ≥51-year-old, respectively (95% CI. The coefficient of variation was <10% for both intra- and interobserver analysis. The results of the present study showed no significant difference in TTTG value between males and females in different age groups. In addition, it demonstrated that MRI is a reliable method in assessment of TTTG and identified normal value for TTTG at 10.9±2.5 mm.

Thermal loads on tokamak plasma-facing components during normal operation and disruptions
International Nuclear Information System (INIS)
McGrath, R.T.
1990-01-01
Power loadings experienced by tokamak plasma-facing components during normal operation and during off-normal events are discussed. A model for power and particle flow in the tokamak boundary layer is presented and model predictions are compared to infrared measurements of component heating. The inclusion of the full three-dimensional geometry of the components and of the magnetic flux surface is very important in the modeling. Experimental measurements show that misalignment of component armour tile surfaces by only a millimeter can lead to significant localized heating. An application to the design of plasma-facing components for future machines is presented. Finally, thermal loads expected during tokamak disruptions are discussed. The primary problems are surface melting and vaporization due to localized intense heating during the disruption thermal quench and volumetric heating of the component armour and structure due to localised impact of runaway electrons.

Full Text Available Active experiencing (AE is an intervention aimed at attenuating cognitive declines with mindfulness training via an immersive acting program, and has produced promising results in older adults with limited formal education. Yet, the cognitive mechanism(s of intervention benefits and generalizability of gains across cognitive domains in the course of healthy aging is unclear. We addressed these issues in an intervention trial of older adults (N = 179; mean age = 69.46 years at enrollment; mean education = 16.80 years assigned to an AE condition (n = 86 or an active control group (i.e., theatre history; n = 93 for 4 weeks. A cognitive battery was administered before and after intervention, and again at a 4-month follow-up. Group differences in change in cognition were tested in latent change score models (LCSM. In the total sample, several cognitive abilities demonstrated significant repeated-testing gains. AE produced greater gains relative to the active control only in episodic recall, with gains still evident up to 4 months after intervention. Intervention conditions were similar in the magnitude of gains in working memory, executive function and processing speed. Episodic memory is vulnerable to declines in aging and related neurodegenerative disease, and AE may be an alternative or supplement to traditional cognitive interventions with older adults.

Full Text Available Following proper activation, naïve “CD4lo” T cells differentiate into effector T cells with enhanced expression of CD4 -“CD4hi” effectors. Autoimmune diabetes-prone NOD mice display a unique set of antigen-experienced “CD4lo” T cells that persist after primary stimulation. Here, we report that a population of such cells remained after secondary and tertiary TCR stimulation and produced cytokines upon antigenic challenge. However, when NOD blasts were induced in the presence of rIL-15, the number of antigen-experienced “CD4lo” T cells was significantly reduced. Clonal contraction, mediated in part by CD95-dependent activation-induced cell death (AICD, normally regulates the accumulation of “CD4hi” effectors. Interestingly, CD95 expression was dramatically reduced on the AICD-resistant NOD “CD4lo” T cells. Thus, while autoimmune disease has often been attributed to the engagement of robust autoimmunity, we suggest that the inability to effectively contract the immune response distinguishes benign autoimmunity from progressive autoimmune diseases that are characterized by chronic T cell-mediated inflammation.

2010-06-01
Full Text Available Knowledge of the entire protein content, the proteome, of normal human cerebrospinal fluid (CSF would enable insights into neurologic and psychiatric disorders. Until now technologic hurdles and access to true normal samples hindered attaining this goal.We applied immunoaffinity separation and high sensitivity and resolution liquid chromatography-mass spectrometry to examine CSF from healthy normal individuals. 2630 proteins in CSF from normal subjects were identified, of which 56% were CSF-specific, not found in the much larger set of 3654 proteins we have identified in plasma. We also examined CSF from groups of subjects previously examined by others as surrogates for normals where neurologic symptoms warranted a lumbar puncture but where clinical laboratory were reported as normal. We found statistically significant differences between their CSF proteins and our non-neurological normals. We also examined CSF from 10 volunteer subjects who had lumbar punctures at least 4 weeks apart and found that there was little variability in CSF proteins in an individual as compared to subject to subject.Our results represent the most comprehensive characterization of true normal CSF to date. This normal CSF proteome establishes a comparative standard and basis for investigations into a variety of diseases with neurological and psychiatric features.

Full Text Available Abstract Background The urinary proteome has been widely used for biomarker discovery. A urinary proteome database from normal humans can provide a background for discovery proteomics and candidate proteins/peptides for targeted proteomics. Therefore, it is necessary to define the minimum number of individuals required for sampling to represent the normal urinary proteome. Methods In this study, inter-individual and inter-gender variations of urinary proteome were taken into consideration to achieve a representative database. An individual analysis was performed on overnight urine samples from 20 normal volunteers (10 males and 10 females by 1DLC/MS/MS. To obtain a representative result of each sample, a replicate 1DLCMS/MS analysis was performed. The minimal sample number was estimated by statistical analysis. Results For qualitative analysis, less than 5% of new proteins/peptides were identified in a male/female normal group by adding a new sample when the sample number exceeded nine. In addition, in a normal group, the percentage of newly identified proteins/peptides was less than 5% upon adding a new sample when the sample number reached 10. Furthermore, a statistical analysis indicated that urinary proteomes from normal males and females showed different patterns. For quantitative analysis, the variation of protein abundance was defined by spectrum count and western blotting methods. And then the minimal sample number for quantitative proteomic analysis was identified. Conclusions For qualitative analysis, when considering the inter-individual and inter-gender variations, the minimum sample number is 10 and requires a balanced number of males and females in order to obtain a representative normal human urinary proteome. For quantitative analysis, the minimal sample number is much greater than that for qualitative analysis and depends on the experimental methods used for quantification.

Experienced physicians benefit from analyzing initial diagnostic hypotheses
Bass, Adam; Geddes, Colin; Wright, Bruce; Coderre, Sylvain; Rikers, Remy; McLaughlin, Kevin
2013-01-01
Background Most incorrect diagnoses involve at least one cognitive error, of which premature closure is the most prevalent. While metacognitive strategies can mitigate premature closure in inexperienced learners, these are rarely studied in experienced physicians. Our objective here was to evaluate the effect of analytic information processing on diagnostic performance of nephrologists and nephrology residents. Methods We asked nine nephrologists and six nephrology residents at the University of Calgary and Glasgow University to diagnose ten nephrology cases. We provided presenting features along with contextual information, after which we asked for an initial diagnosis. We then primed participants to use either hypothetico-deductive reasoning or scheme-inductive reasoning to analyze the remaining case data and generate a final diagnosis. Results After analyzing initial hypotheses, both nephrologists and residents improved the accuracy of final diagnoses (31.1% vs. 65.6%, p inductive reasoning (odds ratio [95% confidence interval] 5.69 [1.59, 20.33], p = 0.07), whereas the performance of experienced nephrologists did not differ between strategies (odds ratio 0.57 [0.23, 1.39], p = 0.20). Discussion Experienced nephrologists and nephrology residents can improve their performance by analyzing initial diagnostic hypotheses. The explanation of the interaction between experience and the effect of different reasoning strategies is unclear, but may relate to preferences in reasoning strategy, or the changes in knowledge structure with experience.

Although both tipranavir (TPV) and darunavir (DRV) represent important options for the management of patients with multi-protease inhibitor (PI)-resistant human immunodeficiency virus (HIV), currently there are no studies comparing the effectiveness and safety of these two drugs in the Mexican population. The aim of this study was to compare the effectiveness of TPV versus DRV as a salvage therapy in HIV-1 treatment-experienced patients. This was a comparative, prospective, cohort study. Patients with HIV and triple-class drug resistance evaluated at the Hospital de Infectología "La Raza", National Medical Center, were included. All patients had the protease and retrotranscriptase genotype; resistance mutation interpretation was done using the Stanford database. A total of 35 HIV-1 triple-class drug-resistant patients were analyzed. All of them received tenofovir and raltegravir, 22 received darunavir/ritonavir (DRV/r), and 13 received tipranavir/ritonavir (TPV/r) therapies. The median baseline RNA HIV-1 viral load and CD4+ cell count were 4.34 log (interquartile range [IQR], 4.15-4.72) and 267 cells/mm3 (IQR, 177-320) for the DRV/r group, and 4.14 log (IQR, 3.51-4.85) and 445 cells/mm3 (IQR, 252-558) for the TPV/r group. At week 24 of treatment, 91% of patients receiving DRV/r and 100% of patients receiving TPV/r had an RNA HIV-1 viral load HIV-1 patients who were highly experienced in antiretroviral therapy.

2013-03-01
Full Text Available We analyzed the levels of selected micro-RNAs in normal prostate tissue to assess their potential to indicate tumor foci elsewhere in the prostate. Histologically normal prostate tissue samples from 31 prostate cancer patients and two cancer negative control groups with either unsuspicious or elevated prostate specific antigen (PSA levels (14 and 17 individuals, respectively were analyzed. Based on the expression analysis of 157 microRNAs in a pool of prostate tissue samples and information from data bases/literature, we selected eight microRNAs for quantification by real-time polymerase chain reactions (RT-PCRs. Selected miRNAs were analyzed in histologically tumor-free biopsy samples from patients and healthy controls. We identified seven microRNAs (miR-124a, miR-146a & b, miR-185, miR-16 and let-7a & b, which displayed significant differential expression in normal prostate tissue from men with prostate cancer compared to both cancer negative control groups. Four microRNAs (miR-185, miR-16 and let-7a and let-7b remained to significantly discriminate normal tissues from prostate cancer patients from those of the cancer negative control group with elevated PSA levels. The transcript levels of these microRNAs were highly indicative for the presence of cancer in the prostates, independently of the PSA level. Our results suggest a microRNA-pattern in histologically normal prostate tissue, indicating prostate cancer elsewhere in the organ.

Help for breastfeeding mothers. Support groups.
1991-09-01
Many people including some health workers and physicians believe bottle feeding is just as good as breast feeding, even though bottle feeding poses some dangers to infants. Further, health workers in hospital often are too busy to counsel new mothers in breast feeding or are simply not trained to do so. Moreover, young women often live in areas away from their family and friends thus not living close to women with whom they are familiar and who could guide them in mastering breast feeding skills. So new mothers who want to breast feed have no support, lack confidence, and/or feel they cannot do so because they work or have other responsibilities. Support groups for new breast feeding mothers can provide them with the needed confidence to breast feed by allowing them to discuss concerns with other new mothers and an experienced leader and to learn the advantages of breast feeding, e.g., a breast fed infant is never constipated. A confident experienced woman in breast feeding is best suited to start a support group in a community. She needs to promote the group by talking to health workers and physicians and advertising at maternity hospitals, women's organizations, and health centers. Once the support group has become successful, several mothers can undergo training to start and lead new support groups. If no national breast feeding promotion organization exists to offer advice on starting a support group, the article provides addresses of international organizations. At support group meetings, mothers learn how to breast feed, how to express and store breast milk, breast feed inconspicuously in public, how their bodies work, and about child growth and development. Support group members from the Philippines, Belize, Trinidad and Tobago, Australia, and singapore share their experiences.

The variability problem of normal human walking
DEFF Research Database (Denmark)
Simonsen, Erik B; Alkjær, Tine
2012-01-01
Previous investigations have suggested considerable inter-individual variability in the time course pattern of net joint moments during normal human walking, although the limited sample sizes precluded statistical analyses. The purpose of the present study was to obtain joint moment patterns from...... a group of normal subjects and to test whether or not the expected differences would prove to be statistically significant. Fifteen healthy male subjects were recorded on video while they walked across two force platforms. Ten kinematic and kinetic parameters were selected and input to a statistical...... cluster analysis to determine whether or not the 15 subjects could be divided into different 'families' (clusters) of walking strategy. The net joint moments showed a variability corroborating earlier reports. The cluster analysis showed that the 15 subjects could be grouped into two clusters of 5 and 10...

Facilitating Group Decision-Making: Facilitator's Subjective Theories on Group Coordination
Directory of Open Access Journals (Sweden)
Michaela Kolbe
2008-10-01
Full Text Available A key feature of group facilitation is motivating and coordinating people to perform their joint work. This paper focuses on group coordination which is a prerequisite to group effectiveness, especially in complex tasks. Decision-making in groups is a complex task that consequently needs to be coordinated by explicit rather than implicit coordination mechanisms. Based on the embedded definition that explicit coordination does not just happen but is purposely executed by individuals, we argue that individual coordination intentions and mechanisms should be taken into account. Thus far, the subjective perspective of coordination has been neglected in coordination theory, which is understandable given the difficulties in defining and measuring subjective aspects of group facilitation. We therefore conducted focused interviews with eight experts who either worked as senior managers or as experienced group facilitators and analysed their approaches to group coordination using methods of content analysis. Results show that these experts possess sophisticated mental representations of their coordination behaviour. These subjective coordination theories can be organised in terms of coordination schemes in which coordination-releasing situations are facilitated by special coordination mechanisms that, in turn, lead to the perception of specific consequences. We discuss the importance of these subjective coordination theories for effectively facilitating group decision-making and minimising process losses. URN: urn:nbn:de:0114-fqs0901287

The purpose of this study was to prospectively evaluate the effect of benzyl alcohol, a common preservative in normal saline, on postprocedural pain after intraarticular injection for direct shoulder MR arthrography. From April 2011 through January 2013, 138 patients underwent direct shoulder MR arthrography. Using the Wong-Baker Faces Pain Scale, patients were asked to report their shoulder pain level immediately before and immediately after the procedure and then were contacted by telephone 6, 24, and 48 hours after the procedure. Fourteen patients did not receive the prescribed amount of contrast agent for diagnostic reasons or did not complete follow-up. Sixty-two patients received an intraarticular solution including preservative-free normal saline (control group) and 62 patients received an intraarticular solution including normal saline with 0.9% benzyl alcohol as a contrast diluent (test group). Patients were randomized as to which intraarticular diluent they received. Fluoroscopic and MR images were reviewed for extracapsular contrast agent administration or extravasation, full-thickness rotator cuff tears, and adhesive capsulitis. The effect of preservative versus control on pain level was estimated with multiple regression, which included time after procedure as the covariate and accounted for repeated measures over patients. Pain scale scores were significantly (p = 0.0382) higher (0.79 units; 95% CI, 0.034-1.154) with benzyl alcohol preservative compared with control (saline). In both study arms, the pain scale scores decreased slightly after the procedure, increased by roughly 1 unit over baseline for the test group and 0.3 unit over baseline for the control group by 6 hours after the procedure, were 0.50 unit over baseline for the test group and 0.12 unit over baseline for the control group at 24 hours, then fell to be slightly greater than baseline at 48 hours with benzyl alcohol and slightly less than baseline without benzyl alcohol.

The neural mechanisms of re-experiencing mental fatigue sensation: a magnetoencephalography study.
Directory of Open Access Journals (Sweden)
Akira Ishii
Full Text Available There have been several studies which have tried to clarify the neural mechanisms of fatigue sensation; however fatigue sensation has multiple aspects. We hypothesized that past experience related to fatigue sensation is an important factor which contributes to future formation of fatigue sensation through the transfer to memories that are located within specific brain structures. Therefore, we aimed to investigate the neural mechanisms of fatigue sensation related to memory. In the present study, we investigated the neural activity caused by re-experiencing the fatigue sensation that had been experienced during a fatigue-inducing session. Thirteen healthy volunteers participated in fatigue and non-fatigue experiments in a crossover fashion. In the fatigue experiment, they performed a 2-back test session for 40 min to induce fatigue sensation, a rest session for 15 min to recover from fatigue, and a magnetoencephalography (MEG session in which they were asked to re-experience the state of their body with fatigue that they had experienced in the 2-back test session. In the non-fatigue experiment, the participants performed a free session for 15 min, a rest session for 15 min, and an MEG session in which they were asked to re-experience the state of their body without fatigue that they had experienced in the free session. Spatial filtering analyses of oscillatory brain activity showed that the delta band power in the left Brodmann's area (BA 39, alpha band power in the right pulvinar nucleus and the left BA 40, and beta band power in the left BA 40 were lower when they re-experienced the fatigue sensation than when they re-experienced the fatigue-free sensation, indicating that these brain regions are related to re-experiencing the fatigue sensation. Our findings may help clarify the neural mechanisms underlying fatigue sensation.

Authentic leadership, empowerment and burnout: a comparison in new graduates and experienced nurses.
Laschinger, Heather K Spence; Wong, Carol A; Grau, Ashley L
2013-04-01
To examine the effect of authentic leadership and structural empowerment on the emotional exhaustion and cynicism of new graduates and experienced acute-care nurses. Employee empowerment is a fundamental component of healthy work environments that promote nurse health and retention, and nursing leadership is key to creating these environments. In a secondary analysis of data from two studies we compared the pattern of relationships among study variables in two Ontario groups: 342 new graduates with Authentic leadership significantly and negatively influenced emotional exhaustion and cynicism through workplace empowerment in both groups. The authentic behaviour of nursing leaders was important to nurses' perceptions of structurally empowering conditions in their work environments, regardless of experience level, and ultimately contributed to lower levels of emotional exhaustion and cynicism. Leadership training for nurse managers may help develop the empowering work environments required in today's health-care organizations in order to attract and retain nurses. © 2012 Blackwell Publishing Ltd.

Full Text Available Background: In chronic kidney disease (CKD intact parathyroid hormone (iPTH level is often increased before clinical hyperphosphatemia occurs. Despite its importance very few studies evaluated parathyroid status in CKD. Objective: The study was undertaken to estimate level of parathormone in diabetic CKD patients at a tertiary level hospital and assessing its relationship with different parameters like hemoglobin, calcium etc. and comparing biochemical and clinical variables between normal parathyroid and hyperparathyroid groups. Materials and Methods: It was a hospital based cross-sectional study involving purposively selected chronic kidney disease patients attending nephrology and endocrinology outdoor and indoor services of BIRDEM hospital, Dhaka, Bangladesh. Study was conducted during the period of April to October 2010. All the subjects were divided into two groups based on serum parathormone level and different parameters were compared between groups. Results: The mean duration of chronic kidney disease was significantly higher in hyperparathyroid group than that in the normal group (<0.001. Retinopathy and hypertension were more common in hyperparathyroid group than that in patients with normal serum parathormone (p<0.001 and p=0.012. Neuropathy was solely present in hyperparathyroid group (p<0.001. Mean fasting blood glucose, serum creatinine and serum phosphate were significantly higher in the hyperparathyroid group compared to normal group (p<0.001 in all cases while the mean serum calcium and haemoglobin were lower in hyperparathyroid group than those in the normal group (p<0.001 in both cases. Serum creatinine and serum parathormone bears a significantly linear relationship (r=0.986, p<0.001, while serum parathormone and serum calcium bears a significantly negative relationship (r=−0.892 and p<0.001. Conclusion: Earlier intervention on the basis of iPTH in addition to other biochemical parameters of chronic kidney disease is

Enhanced disease characterization through multi network functional normalization in fMRI.
Çetin, Mustafa S; Khullar, Siddharth; Damaraju, Eswar; Michael, Andrew M; Baum, Stefi A; Calhoun, Vince D
2015-01-01
Conventionally, structural topology is used for spatial normalization during the pre-processing of fMRI. The co-existence of multiple intrinsic networks which can be detected in the resting brain are well-studied. Also, these networks exhibit temporal and spatial modulation during cognitive task vs. rest which shows the existence of common spatial excitation patterns between these identified networks. Previous work (Khullar et al., 2011) has shown that structural and functional data may not have direct one-to-one correspondence and functional activation patterns in a well-defined structural region can vary across subjects even for a well-defined functional task. The results of this study and the existence of the neural activity patterns in multiple networks motivates us to investigate multiple resting-state networks as a single fusion template for functional normalization for multi groups of subjects. We extend the previous approach (Khullar et al., 2011) by co-registering multi group of subjects (healthy control and schizophrenia patients) and by utilizing multiple resting-state networks (instead of just one) as a single fusion template for functional normalization. In this paper we describe the initial steps toward using multiple resting-state networks as a single fusion template for functional normalization. A simple wavelet-based image fusion approach is presented in order to evaluate the feasibility of combining multiple functional networks. Our results showed improvements in both the significance of group statistics (healthy control and schizophrenia patients) and the spatial extent of activation when a multiple resting-state network applied as a single fusion template for functional normalization after the conventional structural normalization. Also, our results provided evidence that the improvement in significance of group statistics lead to better accuracy results for classification of healthy controls and schizophrenia patients.

Introduction. Recent studies suggest that serum alkaline phosphatase may represent a prognostic biomarker in patients with primary sclerosing cholangitis. However, this association remains poorly understood. Therefore, the aim of this study was to investigate the prognostic significance and clinical correlates of alkaline phosphatase normalization in primary sclerosing cholangitis. This was a retrospective cohort study of patients with a new diagnosis of primary sclerosing cholangitis made at an academic medical center. The primary endpoint was time to hepatobiliaryneoplasia, liver transplantation, or liver-related death. Secondary endpoints included occurrence of and time to alkaline phosphatase normalization. Patients who did and did not achieve normalization were compared with respect to clinical characteristics and endpoint-free survival, and the association between normalization and the primary endpoint was assessed with univariate and multivariate Cox proportional-hazards analyses. Eighty six patients were included in the study, with a total of 755 patient-years of follow-up. Thirty-eight patients (44%) experienced alkaline phosphatase normalization within 12 months of diagnosis. Alkaline phosphatase normalization was associated with longer primary endpoint-free survival (p = 0.0032) and decreased risk of requiring liver transplantation (p = 0.033). Persistent normalization was associated with even fewer adverse endpoints as well as longer survival. In multivariate analyses, alkaline phosphatase normalization (adjusted hazard ratio 0.21, p = 0.012) and baseline bilirubin (adjusted hazard ratio 4.87, p = 0.029) were the only significant predictors of primary endpoint-free survival. Alkaline phosphatase normalization, particularly if persistent, represents a robust biomarker of improved long-term survival and decreased risk of requiring liver transplantation in patients with primary sclerosing cholangitis.

Options and pitfalls of normal tissues complication probability models

Dorr, Wolfgang
2011-01-01
Full text: Technological improvements in the physical administration of radiotherapy have led to increasing conformation of the treatment volume (TV) with the planning target volume (PTV) and of the irradiated volume (IV) with the TV. In this process of improvement of the physical quality of radiotherapy, the total volumes of organs at risk exposed to significant doses have significantly decreased, resulting in increased inhomogeneities in the dose distributions within these organs. This has resulted in a need to identify and quantify volume effects in different normal tissues. Today, irradiated volume today must be considered a 6t h 'R' of radiotherapy, in addition to the 5 'Rs' defined by Withers and Steel in the mid/end 1980 s. The current status of knowledge of these volume effects has recently been summarized for many organs and tissues by the QUANTEC (Quantitative Analysis of Normal Tissue Effects in the Clinic) initiative [Int. J. Radiat. Oncol. BioI. Phys. 76 (3) Suppl., 2010]. However, the concept of using dose-volume histogram parameters as a basis for dose constraints, even without applying any models for normal tissue complication probabilities (NTCP), is based on (some) assumptions that are not met in clinical routine treatment planning. First, and most important, dose-volume histogram (DVH) parameters are usually derived from a single, 'snap-shot' CT-scan, without considering physiological (urinary bladder, intestine) or radiation induced (edema, patient weight loss) changes during radiotherapy. Also, individual variations, or different institutional strategies of delineating organs at risk are rarely considered. Moreover, the reduction of the 3-dimentional dose distribution into a '2dimensl' DVH parameter implies that the localization of the dose within an organ is irrelevant-there are ample examples that this assumption is not justified. Routinely used dose constraints also do not take into account that the residual function of an organ may be

The present study aimed at investigating and comparing patients suffering from β-thalassemia (β-thal) minor with normal individuals in regard to their performances in the short version of the Wechsler Adult Intelligence Scale (WAIS) test. Patients with β-thal minor are carriers of β-thal genes. They have mild microcytic and hypochromic anemia and are usually asymptomatic. In this cross-sectional study, a total of 60 individuals were divided into two equal groups of β-thal minor and normal subjects; they were then studied by the WAIS subscales. The mean performance scores of the normal group in the subtests of arithmetic and vocabulary (p <0.01) and picture completion (p <0.05) were higher than those of the thalassemia group. The mean performance score and ability of the normal group on the verbal scale was higher in comparison to the thalassemia group (p <0.05), while on the non verbal scale, there was no significant difference between the two groups. It can be concluded that β-thal minor negatively influences verbal fluency, reasoning and conceptualization, and sequencing tasks, perceptual skill, prediction of social situations and abstract thinking.

Can human oocyte calcium analysis predict fertilization success after assisted oocyte activation (AOA) in patients experiencing fertilization failure after ICSI? ICSI-AOA restores the fertilization rate only in patients displaying abnormal Ca2+ oscillations during human oocyte activation. Patients capable of activating mouse oocytes and who showed abnormal Ca2+ profiles after mouse oocyte Ca2+ analysis (M-OCA), have variable responses to ICSI-AOA. It remains unsettled whether human oocyte Ca2+ analysis (H-OCA) would yield an improved accuracy to predict fertilization success after ICSI-AOA. Sperm activation potential was first evaluated by MOAT. Subsequently, Ca2+ oscillatory patterns were determined with sperm from patients showing moderate to normal activation potential based on the capacity of human sperm to generate Ca2+ responses upon microinjection in mouse and human oocytes. Altogether, this study includes a total of 255 mouse and 122 human oocytes. M-OCA was performed with 16 different sperm samples before undergoing ICSI-AOA treatment. H-OCA was performed for 11 patients who finally underwent ICSI-AOA treatment. The diagnostic accuracy to predict fertilization success was calculated based on the response to ICSI-AOA. Patients experiencing low or total failed fertilization after conventional ICSI were included in the study. All participants showed moderate to high rates of activation after MOAT. Metaphase II (MII) oocytes from B6D2F1 mice were used for M-OCA. Control fertile sperm samples were used to obtain a reference Ca2+ oscillation profile elicited in human oocytes. Donated human oocytes, non-suitable for IVF treatments, were collected and vitrified at MII stage for further analysis by H-OCA. M-OCA and H-OCA predicted the response to ICSI-AOA in 8 out of 11 (73%) patients. Compared to M-OCA, H-OCA detected the presence of sperm activation deficiencies with greater sensitivity (75 vs 100%, respectively). ICSI-AOA never showed benefit to overcome

Background Smokers are assessed for COPD using spirometry, with COPD defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) as airflow limitation not fully reversible with bronchodilators. There is a subset of smokers with normal spirometry (by GOLD criteria), who have a low diffusion capacity (DLCO), a parameter linked to emphysema and small airway disease. The natural history of these “normal spirometry/low DLCO” smokers is unknown. Methods From a cohort of 1570 smokers in the New York City metropolitian area, all of whom had normal spirometry, two groups were randomly selected for lung function follow-up: smokers with normal spirometry/normal DLCO (n=59) and smokers with normal spirometry/low DLCO (n=46). All had normal history, physical examination, CBC, urinalysis, HIV status, α1-antitrypsin level, chest X-ray, FEV1, FVC, FEV1/FVC ratio and total lung capacity (TLC). Throughout the study, all continued to be active smokers. Findings In the normal spirometry/normal DLCO group assessed over 45 ± 20 months, 3% developed GOLD-defined COPD. In contrast, in the normal spirometry/low DLCO group, followed over 41 ± 31 months, 22% developed GOLD-defined COPD. Interpretation Despite appearing “normal” by GOLD, smokers with normal spirometry but low DLCO are at significant risk for developing COPD with obstruction to airflow. PMID:26541521

This critical review evaluates the existing primary research literature to identify experienced registered nurses' attitudes, views and expectations of graduate nurses which may create a barrier for optimal graduate nurse performance. Relevant primary studies were identified by searching online databases using a wide variety of appropriate keyword combinations. Online databases including Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, PsycINFO and Google Scholar were comprehensively searched for relevant research. The selected studies were subjected to a rigorous critical appraisal to evaluate the studies and to determine if the findings were applicable to practice. A manual method of thematic analysis was conducted to highlight explicit and implicit themes from the reviewed studies. Themes were grouped and continually reduced until only essential themes remain. Themes and subthemes emerged which were then compared and contrasted to analyse results. The four major themes identified include nursing skills, inadequate preparation during academic program, attitudes and ward culture and concerns with confidence. Subthemes were identified within these categories. Findings indicate experienced registered nurses discussed themes including 'nursing skills', 'inadequate preparation during academic program', 'attitudes and ward culture' and 'concerns with confidence'. Concerns were raised including the value of traditional training versus tertiary education programs, coping with unprofessional behaviour and inadequate preparation for practice. Further research is required to fully address management of the theory-practice gap, as well as the attitudes of experienced registered nurses educated in traditional programs versus those in tertiary education programs. Nurse managers should be aware of the possible occurrence of unprofessional behaviour, and increased workplace training regarding lateral violence would assist in raising awareness regarding

Full Text Available The article described the study of the relevance of the role and place of religious contents among young people in the postconflict areas of the South of Russia, the rate of experiences of mythological fear had been explored with the help of the survey, as well as individual psychological characteristics of subjects had been studied by methods of Eysenck, Schmieschek, J. Rotter and Taylor. Those representatives of the surveyed youth sample experiencing a high level of mythological fear could fall into the danger zone of initiation in the group of non-traditional religious sects, as well as come under extremists’ influence, since manip-ulation of consciousness and human behavior, depending on individual psychological characteristics and by using of mythological content, such as fear of possession by jinni, is most effective. The study was attended by representatives of Islam at the age of 19-21, divided by gender: 100 young men and 100 girls. The study was aimed at identifying indi-vidual personality characteristics of temperament, character accentuations, locus of control, the level of personal anxiety and the results of a content analysis of the survey done by the author of the article were identified in accordance with five scales. Results of the study revealed that about 80% of subjects experiencing a high level of mythological fears had the same peculiar correlation indices. In connection with the results of research, we had worked out and suggested a complex of psycho-pedagogical support consisting of four modules for the purpose of education, preventive and corrective activities with young people experiencing a high level of mythological fear (fear of possession by jinni.

There has been limited investigation of parturition in the bitch and there is little information published on clinical and obstetrical examination other than opinion and anecdote. While there are substantial data on haemodynamic and vascular changes during normal parturition in humans, little is known about the physiological events in the dog. This study was aimed at maternal haemodynamic changes occurring during normal parturition and to investigate how these were modified in bitches with dystocia (DYST) treated either medically or via assisted delivery and caesarean operation. Three groups of 10 bitches were investigated; those with normal parturition, those with DYST corrected by manipulative assistance or caesarean operation and those with uterine inertia treated by oxytocin administration. Heart rate, systolic and diastolic blood pressure, electrocardiogram and blood glucose concentration were measured pre-partum, intra-partum, immediately after parturition and 1 h later. Heart rate was high at all times throughout the study and the majority of bitches had normal sinus rhythm. Blood pressure was generally within the normal range, and although systolic and diastolic blood pressure was highest during the intra-partum period and sometimes during the immediate post-partum period, there were no significant differences between groups. All bitches had blood glucose concentrations within the normal range throughout the study although pre-partum concentrations were statistically lower than many of the other time periods. The study provides useful physiological data that will facilitate monitoring and clinical management of bitches throughout normal parturition and DYST.

In this study, we evaluated a large number of subjects using BOLD MRI to provide more information about oxygen metabolism in the normal function of transplanted kidneys and to distinguish acute graft rejection from normal function kidneys. This study included 122 subjects (20 volunteers, 72 patients with normal functioning transplants, and 21 patients with acute rejection), and 9 patients had normal function grafts received examination while grafts dysfunction occurred within 6 months during the follow-up. The R2* (1/s) values in the cortex and medulla as well as the R2* ratio of the medulla to cortex (R2* ratio of M/C) were recorded. The R2* values of the medulla were higher than those of the cortex in the normal function group and the volunteers which have a steep R2* ratio of M/C. All the R2* values in the acute rejection group were lower than those in the normal function grafts group (P 1.1) is an important reason for keeping clinical normal function.

Thyroid storm is a rare disorder with a sudden onset, rapid progression and high mortality. We experienced a case of thyroid storm which had a devastating course, including multiple organ failure (MOF), severe hypoglycemia, disseminated intravascular coagulation (DIC), and stroke. It was difficult to make a diagnosis of thyroid storm in the present patient, because she did not have a history of thyroid disease and her serum FT3 level was normal. Clinicians should be aware that thyroid storm can occur even when there is an almost normal level of thyroid hormones, and that intensive anticoagulation is required for patients with atrial fibrillation to prevent stroke after thyroid storm.

Full Text Available The aim of this study was to determine the effect of caffeine intake on overall basketball performance in experienced players. A double-blind, placebo-controlled, randomized experimental design was used for this investigation. In two different sessions separated by one week, 20 experienced basketball players ingested 3 mg of caffeine/kg of body mass or a placebo. After 60 min, participants performed 10 repetitions of the following sequence: Abalakov jump, Change-of-Direction and Acceleration Test (CODAT and two free throws. Later, heart rate, body impacts and game statistics were recorded during a 20-min simulated basketball game. In comparison to the placebo, the ingestion of caffeine increased mean jump height (37.3 ± 6.8 vs. 38.2 ± 7.4 cm; p = 0.012, but did not change mean time in the CODAT test or accuracy in free throws. During the simulated game, caffeine increased the number of body impacts (396 ± 43 vs. 410 ± 41 impacts/min; p < 0.001 without modifying mean or peak heart rate. Caffeine also increased the performance index rating (7.2 ± 8.6 vs. 10.6 ± 7.1; p = 0.037 during the game. Nevertheless, players showed a higher prevalence of insomnia (19.0 vs. 54.4%; p = 0.041 after the game. Three mg of caffeine per kg of body mass could be an effective ergogenic substance to increase physical performance and overall success in experienced basketball players.

The purpose of this study was to investigate the effects of eyeball exercise on balance and fall efficacy of the elderly who have experienced a fall. Subjects were randomly assigned to the eyeball exercise group (n=30) or functional exercise group (n=31). All subjects received 30 sessions for 10 weeks. To identify the effects on balance, static and dynamic balance were measured using the center of pressure (CoP) measurement equipment and Timed Up and Go Test (TUGT) respectively. Fall efficacy was evaluated using the modified efficacy scale (MFES). The outcome measurements were performed before and after the 10 weeks training period. After 10 weeks, static balance, dynamic balance, and fall efficacy were significantly improved in both groups. Also, there were significant differences in the outcome measures between both groups (peyeball exercise is beneficial to improve the fall efficacy as well as the balance of the elderly compared with functional exercise. Eyeball exercise would be useful to improve balance and fall efficacy of the elderly who have experienced a fall. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Background: Childhood obesity has become a major concern in recent years. The increasing childhood obesity prevalence may occur as the result of food consumption with high content of calories, fat, cholesterol and the lack of physical activity. Obesity in children will also affect their pubertal development. Puberty is a period in which maturation of the reproductive function is achieved.In girls, the initial sign of puberty is thelarche, defined as the appearance of breast bud underneath the areola.The onset of puberty depends on many factors, one of them is nutritional status especially obesity. This study was conducted to compare the age of thelarche between obese and normal girls. Methods: An analytical study using cross sectional method was conducted. This study was held in Bandung, West Java, Indonesia, during the period of SeptemberOctober 2013. Data were obtained from 3 elementary schools, selected by multistage random sampling.The total subject was 46. Data were analyzed using the Mann-Whitney and chi-square test. Results: Thelarche occurred at age 9 years 4 months in the obese group compared to 11 years 2 months in the normal group. The analysis using Mann-Whitney test showed the difference was statistically significant (p<0.001. Based on age group, 42% obese girls attained thelarche between ages 89 years, while 63% girls in the normal group attained thelarche between ages 1112 years. The analysis using chi- square test showed that the difference was statistically significant (p<0.001. Conclusions: Thelarche occurs earlier in obese girls compared to normal girls.

Experienced stigma and its impacts in psychosis: The role of social rank and external shame.
Wood, Lisa; Irons, Chris
2017-09-01
Experienced stigma is detrimental to those who experience psychosis and can cause emotional distress and hinder recovery. This study aimed to explore the relationship between experienced stigma with emotional distress and recovery in people with psychosis. It explored the role of external shame and social rank as mediators in these relationships. A cross-sectional design was implemented. Fifty-two service users were administered a battery of questionnaires examining experienced stigma, external shame, social rank, personal recovery, positive symptoms, depression, and anxiety. Correlation and multiple regression analysis were conducted on the data. Where appropriate, mediation analysis was employed to explore social rank and external shame as mediatory variables. Experienced stigma was significantly related to shame (social rank and external shame), positive symptoms, emotional distress (depression and anxiety), and personal recovery. The impact of experienced stigma on depression was mediated by external shame. Social rank was a mediator between experienced stigma and personal recovery only. People with psychosis who have experienced stigma are likely to experience emotional distress and be inhibited in their recovery. This was found to be partly mediated by external shame and low social rank. Clinical approaches to stigma need to target these as potential maintenance factors. Experienced stigma is significantly related to shame (social rank and external shame) emotional distress, and reduced personal recovery. External shame mediated the relationship between experienced stigma and depression in psychosis. Social rank mediated the relationship between experienced stigma and personal recovery. Clinical approaches to stigma should include the assessment of external shame and low social rank. © 2017 The British Psychological Society.

The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1) and those diagnosed without acute coronary syndrome (Group 2). Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

Two studies demonstrated that different negatively stereotyped groups are at risk for distinct forms of stereotype threats. The Multi-Threat Framework articulates six distinct stereotype threats and the unique constellations of variables (e.g., group identification, stereotype endorsement) that elicit each stereotype threat. Previous research suggests that different negatively stereotyped groups systematically vary across these stereotype threat elicitors; a pilot study confirms these differences. Across two studies, groups that tend to elicit low stereotype endorsement (religion, race/ethnicity, congenital blindness) were less likely to report experiencing self-as-source stereotype threats (stereotype threats requiring stereotype endorsement) and groups that tend to elicit low group identification (mental illness, obesity, blindness later in life) were less likely to report experiencing group-as-target stereotype threats (stereotype threats requiring group identification). This research suggests that traditional models may overlook the experiences of stereotype threats within some groups and that interventions tailored to address differences between stereotype threats will be most effective.

Virtual reality has demonstrated promising results in the treatment of eating disorders (ED); however, few studies have examined its usefulness in treating obesity. The aim of this study was to compare ED and obese patients on their reality judgment of a virtual environment (VE) designed to normalize their eating pattern. A second objective was to study which variables predicted the reality of the experience of eating a virtual forbidden-fattening food. ED patients, obese patients, and a non-clinical group (N=62) experienced a non-immersive VE, and then completed reality judgment and presence measures. All participants rated the VE with similar scores for quality, interaction, engagement, and ecological validity; however, ED patients obtained the highest scores on emotional involvement, attention, reality judgment/presence, and negative effects. The obese group gave the lowest scores to reality judgment/presence, satisfaction and sense of physical space, and they held an intermediate position in the attribution of reality to virtually eating a "fattening" food. The palatability of a virtual food was predicted by attention capturing and belonging to the obese group, while the attribution of reality to the virtual eating was predicted by engagement and belonging to the ED group. This study offers preliminary results about the differential impact on ED and obese patients of the exposure to virtual food, and about the need to implement a VE that can be useful as a virtual lab for studying eating behavior and treating obesity.

Immunoconglutinin levels in normal and diseased population groups in Southern Africa
Watson, K. C.
1971-01-01
Immunoconglutinin (I-K) levels were measured in adult blood donors of European and African origin and in patients with the following diseases: acute typhoid fever, amoebic liver abscess, chronic liver disease and primary hepatoma. The lowest levels were found in the white donor group and the highest in those with chronic liver disease and those with primary hepatoma. African donors had levels higher than white donors which may relate to chronic infection and particularly chronic parasitic infestation. There was poor correlation between `O' and `H' antibodies and I-K levels in the typhoid group. In those with chronic liver disease there was some correlation between I-K levels and total γ-globulin and also with raised IgM and IgA levels but not with raised IgG. PMID:4103887

For nurses, shift work is a necessity, required to provide 24-h continuous care for patients. Research posits that fatigue amongst shift-working nurses is associated with inadequate and poorly timed sleep and also strongly influenced by the timing, quality and quantity of food consumed. The aim of this investigation was to examine differences and similarities in the food choices and eating patterns of nurses exposed to different lengths of time in shift work, as a means of understanding how nurses can adapt their eating patterns to better manage fatigue and sleep loss. Qualitative methodology was utilised to study and capture in-depth information about nurses' daily working lives. A case study approach allowed for the investigation of nurses with limited and extensive experience of shift work. Increased food craving, caffeine consumption and snacking behaviours during night shifts were described by both groups of nurses, as was the inability to drink enough fluids at work. Meal skipping at work, associated with high workload, was detailed more by experienced nurses. Experienced nurses described shopping and preparing home cooked meals in advance to manage food intake and associated fatigue, contrasting with patterns from inexperienced nurses. Experienced nurses recounted drinking alcohol as a way to rest and recover from shift work, unlike their less inexperienced colleagues. These findings indicate organisational and work place issues such as shift work and rostering influence the food choices and eating patterns of shift-working nurses. Experienced nurses, however, draw on a greater range of strategies around diet and eating patterns to minimise these impacts.

Virtual Distance and Soundstage, and their Impacts on Experienced Emotional Valence
DEFF Research Database (Denmark)
Christensen, Justin
2015-01-01
stimuli should cause stronger valenced responses in the nearfield than at a distance. Thus, music experienced as being negatively valenced at a distance should be more negatively valenced in nearfield, and music that is experienced as having a positive valence at a distance should be more positively......Research from animal ethology and affective neuroscience suggest that a listener’s perceived distance from a signal source can alter their experienced emotional valence of the music. Furthermore, appraisal theories of emotion suggest that emotionally valenced responses will diverge according...... to the type of emotion presented. For these exploratory investigations, subjects listen to selected musical excerpts on speakers in combination with a tactile transducer attached to their chair. The listening sessions are recorded on EEG supported by subject feedback responses. My hypothesis is that musical...

Immunophenotype of primary cutaneous diffuse large B-cell lymphoma, leg-type (PCLBCL-LT) suggests a germinal center-experienced B lymphocyte (BCL2+ MUM1+ BCL6+/-). As maturation history of B-cell is "imprinted" during B-cell development on the immunoglobulin gene sequence, we studied the structure and sequence of the variable part of the genes (IGHV, IGLV, IGKV), immunoglobulin surface expression and features of class switching in order to determine the PCLBCL-LT cell of origin. Clonality analysis with BIOMED2 protocol and VH leader primers was done on DNA extracted from frozen skin biopsies on retrospective samples from 14 patients. The clonal DNA IGHV sequence of the tumor was aligned and compared with the closest germline sequence and homology percentage was calculated. Superantigen binding sites were studied. Features of selection pressure were evaluated with the multinomial Lossos model. A functional monoclonal sequence was observed in 14 cases as determined for IGHV (10), IGLV (2) or IGKV (3). IGV mutation rates were high (>5%) in all cases but one (median:15.5%), with superantigen binding sites conservation. Features of selection pressure were identified in 11/12 interpretable cases, more frequently negative (75%) than positive (25%). Intraclonal variation was detected in 3 of 8 tumor specimens with a low rate of mutations. Surface immunoglobulin was an IgM in 12/12 cases. FISH analysis of IGHM locus, deleted during class switching, showed heterozygous IGHM gene deletion in half of cases. The genomic PCR analysis confirmed the deletions within the switch μ region. IGV sequences were highly mutated but functional, with negative features of selection pressure suggesting one or more germinal center passage(s) with somatic hypermutation, but superantigen (SpA) binding sites conservation. Genetic features of class switch were observed, but on the non functional allele and co-existing with primary isotype IgM expression. These data suggest that cell-of origin is

The purpose of this study is to evaluate the freeze-all strategy in subgroups of normal responders, to assess whether this strategy is beneficial regardless of ovarian response, and to evaluate the possibility of implementing an individualized embryo transfer (iET) based on ovarian response. This was an observational, cohort study performed in a private IVF center. A total of 938 IVF cycles were included in this study. The patients were submitted to controlled ovarian stimulation (COS) with a gonadotropin-releasing hormone (GnRH) antagonist protocol and a cleavage-stage day 3 embryo transfer. We performed a comparison of outcomes between the fresh embryo transfer (n = 523) and the freeze-all cycles (n = 415). The analysis was performed in two subgroups of patients based on the number of retrieved oocytes: Group 1 (4-9 oocytes) and Group 2 (10-15 oocytes). In Group 1 (4-9 retrieved oocytes), the implantation rates (IR) were 17.9 and 20.5% (P = 0.259) in the fresh and freeze-all group, respectively; the ongoing pregnancy rates (OPR) were 31 and 33% (P = 0.577) in the fresh and freeze-all group, respectively. In Group 2 (10-15 oocytes), the IR were 22.1 and 30.1% (P = 0.028) and the OPR were 34 and 47% (P = 0.021) in the fresh and freeze-all groups, respectively. Although the freeze-all policy may be related to better in vitro fertilization (IVF) outcomes in normal responders, these potential advantages decrease with worsening ovarian response. Patients with poorer ovarian response do not benefit from the freeze-all strategy.

Workplace violence experienced by registered nurses: a concept analysis.
Ventura-Madangeng, Judee; Wilson, Denise
2009-11-01
Workplace violence toward nurses has increased during the last decade with serious consequences that may extend beyond individual nurses to an entire health care organisation. The variety of definitions of workplace violence experienced by registered nurses contribute to a lack of clarity about what it constitutes, which in turn jeopardizes the reporting of incidences by nurses. Drawing on the relevant literature from 1990 to 2005, a concept analysis using Walker and Avant's framework was undertaken to develop an operational definition of this phenomenon as experienced by registered nurses (excluding mental health nurses). Having a clear understanding of workplace violence assists with the creation of strategies aimed at preventing and/or resolving this problem.

Healthcare personnel in the municipal healthcare systems experience many ethical challenges in their everyday work. In Norway, 243 municipalities participated in a national ethics project, aimed to increase ethical competence in municipal healthcare services. In this study, we wanted to map out what participants in ethics reflection groups experienced as promoters or as barriers to successful reflection. To examine what the staff experience as promoters or as barriers to successful ethics reflection. The study has a qualitative design, where 56 participants in municipal healthcare participated in 10 different focus-group interviews. Ethical considerations: The data collection was based on the participants' informed consent and approved by the Data Protection Official of the Norwegian Centre for Research Data. The informants had different experiences from ethics reflection group. Nevertheless, we found that there were several factors that were consistently mentioned: competence, facilitator's role, ethics reflection groups organizing, and organizational support were all experienced as promoters and as a significant effect on ethics reflection groups. The absence of such factors would constitute important barriers to successful ethics reflection. The results are coincident with other studies, and indicate some conditions that may increase the possibility to succeed with ethics reflection groups. A systematic approach seems to be important, the systematics of the actual reflections, but also in the organization of ethics reflection group at the workplace. Community healthcare is characterized by organizational instabilities as many vacancies, high workloads, and lack of predictability. This can be a hinder for ethics reflection group. Both internal and external factors seem to influence the organization of ethics reflection group. The municipalities' instabilities challenging this work, and perceived as a clear inhibitor for the development. The participants

Normal vibrations in gallium arsenide
International Nuclear Information System (INIS)
Dolling, G.; Waugh, J.L.T.
1964-01-01
The triple axis crystal spectrometer at Chalk River has been used to observe coherent slow neutron scattering from a single crystal of pure gallium arsenide at 296 o K. The frequencies of normal modes of vibration propagating in the [ζ00], (ζζζ], and (0ζζ] crystal directions have been determined with a precision of between 1 and 2·5 per cent. A limited number of normal modes have also been studied at 95 and 184 o K. Considerable difficulty was experienced in obtaining welt resolved neutron peaks corresponding to the two non-degenerate optic modes for very small wave-vector, particularly at 296 o K. However, from a comparison of results obtained under various experimental conditions at several different points in reciprocal space, frequencies (units 10 12 c/s) for these modes (at 296 o K) have been assigned: T 8·02±0·08 and L 8·55±02. Other specific normal modes, with their measured frequencies are (a) (1,0,0): TO 7·56 ± 008, TA 2·36 ± 0·015, LO 7·22 ± 0·15, LA 6·80 ± 0·06; (b) (0·5, 0·5, 0·5): TO 7·84 ± 0·12, TA 1·86 ± 0·02, LO 7·15 ± 0·07, LA 6·26 ± 0·10; (c) (0, 0·65, 0·65): optic 8·08 ±0·13, 7·54 ± 0·12 and 6·57 ± 0·11, acoustic 5·58 ± 0·08, 3·42 · 0·06 and 2·36 ± 004. These results are generally slightly lower than the corresponding frequencies for germanium. An analysis in terms of various modifications of the dipole approximation model has been carried out. A feature of this analysis is that the charge on the gallium atom appears to be very small, about +0·04 e. The frequency distribution function has been derived from one of the force models. (author)

Paraspinal muscle fatigue mechanisms were compared in 14 primary fibromyalgia patients and 14 age and sex matched normal subjects using a standardized 60-s isometric endurance test of the paraspinal muscles, during which surface integrated electromyographic (IEMG) activity was recorded. Fatigue-induced IEMG increases were similar for both groups during the initial 40 s (up to 112 +/- 20% and 111 +/- 6% of initial values in patients and normal subjects respectively). Thereafter, IEMG fell significantly in patients (P BMI, range 19-25 in controls) those with a BMI BMI > 26 (n = 9) showed greater IEMG declines after 40 s than either normal subjects or in the fibromyalgia group as a whole. Paraspinal muscle fatigue mechanisms appear normal in primary fibromyalgia patients. Isometric force maintenance in overweight patients, despite IEMG declines, illustrates the action of intrinsic fatigue resistance mechanisms which were presumably utilized to a greater extent in these patients to cope with the extra load.

Full Text Available In order to elucidate meanings of being received and met by others as experienced by women with multiple sclerosis (MS we conducted a qualitative inquiry. We interviewed 15 women with MS and analysed the interviews with a phenomenological hermeneutic interpretation. The findings were presented in two themes: experiencing oneself as a valuable person and experiencing oneself as diminished. Meanings of being received and met by others, as experienced by women with MS, can be understood as containing two dimensions where treatment from others can mean recognising oneself through confirmation, as well as being ignored due to missing togetherness with others.

Experiencing the changing climate on the shores of Lake Superior
Akerlof, K.; Maibach, E.
2011-12-01
The Great Lakes of the United States - the largest freshwater system in the world - have been termed "the canary in the coal mine" of environmental change. To assess if and how residents of Alger County, Michigan are experiencing changes in climate on the shores of Lake Superior, during the summer of 2010 we conducted a representative household mail survey in collaboration with a national lakeshore and watershed partnership. A total of 765 adult residents (18 years or older) responded to the survey; a 57% survey completion rate. We content analyzed respondents' open-ended characterizations of how they have personally experienced global warming, and compared the results with land surface and storm data for the same geographic region to see whether public perceptions of local changes match trends in National Climatic Data Center data. Just over a quarter of residents (27%) indicated that they had personally experienced global warming. Those who had were most likely to say that they had experienced global warming locally (as opposed to in other locations of the country or globally), and most frequently cited changes in seasons, weather, lake levels, and animals or plant species. However, some local public perceptions appeared to conflict with weather records. For example, residents were more likely to say that they had been experiencing less snow in the winters, while NCDC data suggests the reverse is true. As climate changes differentially in regions across the United States, the public will in turn experience its physical impacts in distinct ways that are unique to each landscape. This may be counter-intuitive to a public that increasingly experiences the world, and issues such as climate change, through sources of information such as national news media that operate at much larger geographic scales. Understanding where these forms of cognitive dissonance may arise may assist researchers, educators, and communicators in furthering discourses with the public about

2008-01-01
Full Text Available Affective forecasting with respect to two environmental risks (ozone depletion, air pollution was investigated by studying tourists who travelled to either Australia or Bangkok and were thus confronted with one of these risks. We measured anticipated outcome and anticipated emotions before the journey, actually experienced outcome and actually experienced emotions during the journey, and anticipated outcome and emotions concerning a future encounter with the same risk after the journey. Results indicate that tourists underestimate (air pollution or correctly predict (ozone depletion both the seriousness of the outcome and their emotional reactions. The relationship between actual outcome and actual emotions is stronger than that between anticipated outcome and anticipated emotions. Furthermore, tourists learn from their travel experience and adjust their anticipations concerning future encounters with the environmental risk. Findings suggest that the domain of environmental risks differs from personal outcomes with respect to the process of affective forecasting.

Inter-subject networks are used to model correlations between brain regions and are particularly useful for metabolic imaging techniques, like 18F-2-deoxy-2-(18F)fluoro-D-glucose (FDG) positron emission tomography (PET). Since FDG PET typically produces a single image, correlations cannot be calculated over time. Little focus has been placed on the basic properties of inter-subject networks and if they are affected by group size and image normalization. FDG PET images were acquired from rats (n = 18), normalized by whole brain, visual cortex, or cerebellar FDG uptake, and used to construct correlation matrices. Group size effects on network stability were investigated by systematically adding rats and evaluating local network connectivity (node strength and clustering coefficient). Modularity and community structure were also evaluated in the differently normalized networks to assess meso-scale network relationships. Local network properties are stable regardless of normalization region for groups of at least 10. Whole brain-normalized networks are more modular than visual cortex- or cerebellum-normalized network (p network resolutions where modularity differs most between brain and randomized networks. Hierarchical analysis reveals consistent modules at different scales and clustering of spatially-proximate brain regions. Findings suggest inter-subject FDG PET networks are stable for reasonable group sizes and exhibit multi-scale modularity.

The aim of the study was to evaluate the results of nailfold videocapillaroscopic examination in patients with normal-tension glaucoma (NTG) in comparison to age-matched individuals without glaucoma and young healthy volunteers and to assess the relation between the results of this examination with clinical status in NTG group. The studied group consisted of 188 patients: 80 patients with NTG and 2 control groups (58 young healthy and 50 age-matched volunteers). The nailfold videocapillaroscopy (NVC) was performed in all participants. The results of every NVC were qualified as a normal or abnormal pattern. In the NTG group, ophthalmic examination was performed and medical history regarding glaucoma, chronic general disorders, and vascular risk factors was recorded. In the NTG group, an abnormal NVC pattern was more common than in young controls (p = 0.0008). Microbleedings were present more frequently in NTG patients (p = 0.0365). Enlargement of capillaries (p = 0.0006) and branching capillaries (p = 0.0221) were more frequent in the NTG group compared to age-matched controls. Maximal intraocular pressure was higher in NTG patients with abnormal NVC pattern than with normal NVC (p = 0.0000). Disc hemorrhages were more frequently observed in patients with abnormal NVC pattern (p = 0.0313). Presence of paracentral scotoma was associated with abnormal NVC pattern (p = 0.0054). Abnormalities in nailfold capillaroscopy are more frequent in NTG patients. The results of capillaroscopic examination differ in NTG patients according to the profile of ocular and general risk factor.

Training in medicine must move to an outcome-based approach. A proficiency-based progression outcome approach to training relies on a quantitative estimation of experienced operator performance. We aimed to develop a method for dealing with atypical expert performances in the quantitative definition of surgical proficiency. In study one, 100 experienced laparoscopic surgeons' performances on virtual reality and box-trainer simulators were assessed for two similar laparoscopic tasks. In study two, 15 experienced surgeons and 16 trainee colorectal surgeons performed one simulated hand-assisted laparoscopic colorectal procedure. Performance scores of experienced surgeons in both studies were standardized (i.e. Z-scores) using the mean and standard deviations (SDs). Performances >1.96 SDs from the mean were excluded in proficiency definitions. In study one, 1-5% of surgeons' performances were excluded having performed significantly below their colleagues. Excluded surgeons made significantly fewer correct incisions (mean = 7 (SD = 2) versus 19.42 (SD = 4.6), P 4 SDs for time to complete the procedure and >6 SDs for path length. After their exclusions, experienced surgeons' performances were significantly better than trainees for path length: P = 0.031 and for time: P = 0.002. Objectively assessed atypical expert performances were few. Z-score standardization identified them and produced a more robust quantitative definition of proficiency. © 2018 Royal Australasian College of Surgeons.

Peer Victimization Experienced by Children and Adolescents Who Are Deaf or Hard of Hearing
Kouwenberg, Maartje; Rieffe, Carolien; Theunissen, Stephanie C. P. M.; de Rooij, Mark
2012-01-01
Victimization is a relatively common, yet serious problem, with potentially severe consequences for children's psychosocial and academic functioning. Children who are Deaf or Hard of Hearing (DHH) may be at a higher risk for victimization than hearing children. The aims of the present study were to compare DHH and hearing children on i) self-reported experiences of victimization and ii) associations between victimization, parental- and child variables. In total 188 children (mean age 11;11 years) from the Netherlands and Dutch-speaking part of Belgium participated in the study. No difference between DHH and hearing children were found on general experiences of victimization. However, differences between the groups were found on specific forms of experienced victimization and on the associations between victimization and parental variables. For DHH children, parental sensitivity and parents who challenge their DHH children to become competent in the practical, emotional, cognitive and social domain is associated with them being less victimized. For hearing children at this age these relations were reversed, absent or more complex. Finally, DHH children in special schools were more victimized than DHH children in regular schools. It can be concluded that parents can play an important role in reducing social problems experienced by DHH children and young adolescents. PMID:23284923

Full Text Available Background: Abnormal uterine bleeding (AUB is one of the most common clinical problemsin gynecology. Transvaginal sonography (TVS and hysteroscopy are two diagnostic methods forpatients with AUB. For most of the patients with AUB, diagnostic hysteroscopy can be done inclinic with minimal discomfort and much lower expense than operative room.Materials and Methods: In our clinical trial study, from March 21, 2005 to March 20, 2007,patients with AUB in Ahwaz Imam Khomayni hospital, after history and physical examinationsunderwent TVS. Of those, 147 patients with normal TVS entered the study and were considered foroutpatient hysteroscopy. Patients with endometrial cavity lesion were scheduled for operation room,and those with empty endometrial cavity aspiration biopsy were done outpatiently. Specimens weresent to pathologist for examination.Results: All the patients were divided into three groups: group 1 or minority was under 30 yearsold (7 women, group 2 was 30-40 years, and group 3 or majority was over 40 years old (96women. 115 patients (78.2% had normal and 32 patients (21.8% had abnormal hysteroscopicresults. 116 patients (78.8% had normal and 31 patients (21.2% had abnormal pathologic results;moreover, cervical canal polyp was the most common lesion hysteroscopically and pathologicallyin all groups.Conclusion: Of 147 patients (100% with AUB and normal TVS, 32 patients (21.8% wereabnormal hysteroscopically. Cervical canal polyps may be missed by transvaginal sonography, butcan be diagnosed by hysteroscopy. In patients with AUB and normal TVS, hysteroscopy can beused as the second step.

Data from 16S ribosomal RNA (rRNA) amplicon sequencing present challenges to ecological and statistical interpretation. In particular, library sizes often vary over several ranges of magnitude, and the data contains many zeros. Although we are typically interested in comparing relative abundance of taxa in the ecosystem of two or more groups, we can only measure the taxon relative abundance in specimens obtained from the ecosystems. Because the comparison of taxon relative abundance in the specimen is not equivalent to the comparison of taxon relative abundance in the ecosystems, this presents a special challenge. Second, because the relative abundance of taxa in the specimen (as well as in the ecosystem) sum to 1, these are compositional data. Because the compositional data are constrained by the simplex (sum to 1) and are not unconstrained in the Euclidean space, many standard methods of analysis are not applicable. Here, we evaluate how these challenges impact the performance of existing normalization methods and differential abundance analyses. Effects on normalization: Most normalization methods enable successful clustering of samples according to biological origin when the groups differ substantially in their overall microbial composition. Rarefying more clearly clusters samples according to biological origin than other normalization techniques do for ordination metrics based on presence or absence. Alternate normalization measures are potentially vulnerable to artifacts due to library size. Effects on differential abundance testing: We build on a previous work to evaluate seven proposed statistical methods using rarefied as well as raw data. Our simulation studies suggest that the false discovery rates of many differential abundance-testing methods are not increased by rarefying itself, although of course rarefying results in a loss of sensitivity due to elimination of a portion of available data. For groups with large (~10×) differences in the average

The experience of weight management in normal weight adults.
Hernandez, Cheri Ann; Hernandez, David A; Wellington, Christine M; Kidd, Art
2016-11-01
No prior research has been done with normal weight persons specific to their experience of weight management. The purpose of this research was to discover the experience of weight management in normal weight individuals. Glaserian grounded theory was used. Qualitative data (focus group) and quantitative data (food diary, study questionnaire, and anthropometric measures) were collected. Weight management was an ongoing process of trying to focus on living (family, work, and social), while maintaining their normal weight targets through five consciously and unconsciously used strategies. Despite maintaining normal weights, the nutritional composition of foods eaten was grossly inadequate. These five strategies can be used to develop new weight management strategies that could be integrated into existing weight management programs, or could be developed into novel weight management interventions. Surprisingly, normal weight individuals require dietary assessment and nutrition education to prevent future negative health consequences. Copyright © 2016 Elsevier Inc. All rights reserved.

The objective of this study was to determine whether the GI Mentor II virtual reality simulator can distinguish the psychomotor skills of intermediately experienced endoscopists from those of novices, and do so with a high level of consistency and reliability. A total of five intermediate and nine novice endoscopists were evaluated using the EndoBubble abstract psychomotor task. Each subject performed three repetitions of the task. Performance and error data were recorded for each trial. The intermediate group performed better than the novice group in each trial. The differences were significant in trial 1 for balloons popped (P=.001), completion time (P=.04), and errors (P=.03). Trial 2 showed significance only for balloons popped (P=.002). Trial 3 showed significance for balloons popped (P=.004) and errors (P=.008). The novice group showed significant improvement between trials 1 and 3 (P<0.05). No improvement was noted in the intermediate group. Measures of consistency and reliability were greater than 0.8 in both groups with the exception of novice completion time where test-retest reliability was 0.74. The GI Mentor II simulator can distinguish between novice and intermediate endoscopists. The simulator assesses skills with levels of consistency and reliability required for high-stakes assessment.

Comparing lecture and e-learning as pedagogies for new and experienced professionals in dentistry.
Browne, L; Mehra, S; Rattan, R; Thomas, G
2004-07-24
To evaluate the relative effectiveness of e-learning versus lecture learning in VDPs and trainers. Experimental comparison of two groups' learning retention. VDPs and trainers from two regions were assessed by independent researchers. One region's VDPs and trainers received e-learning; another's received a traditional one hour lecture. Retention and understanding were tested and compared. Personal preference was assessed in group interviews. Significantly greater retention for the trainees occurred from lecturing rather than e-learning, and for the trainers e-learning was significantly more successful than lecturing. Small numbers in this study preclude wide generalisation. However, the results point to the benefits of face-to-face interaction for inexperienced staff, and the benefits of the speed and manageability of e-learning for busy, more experienced staff. The need for a discussion facility to be incorporated into ICT innovations to CPD (via, for example, online 'chatrooms') is also highlighted, with the potential of greatly enhancing e-learning efficacy.

Background: Current research in type 2 diabetes mellitus focuses on the role of Peroxisome-Proliferator Activated Receptors (PPARs) in the pathogenesis of the Insulin Resistance Syndrome (IRS), which are pre-diabetic lesion and the hallmark of fully developed type 2 diabetes mellitus. This study aims at identifying the abnormal status of the PPAR-g in adipose tissues of type 2 diabetes mellitus patients, when compared with matched normal controls. Methods: This cross-sectional study was conducted in Ayub Medical College, Abbottabad, from 2012 to 2014. Sample included three equal groups of patients. Group-1 with diagnosed type 2 diabetes mellitus, aged 40-65 years, acting as the test group, Group-2 included non-diabetic obese, and Group-3 with normal subjects. Transcription Factor Assay for Peroxisome Proliferator Activated Receptor Gamma (gamma PPAR) was done on ELISA Technique from Nuclear Extract procured from Adipose Tissue of the subjects. Results: Mean age of enrolled participants was 48.93 SD±6.52.years. Patients ranged between ages of 40 years to 67 years. The mean values of PPAR in normal, obese and diabetic group were 1.72 SD±0.28, 1.282 SE±0.18 and 1.283 SE±0.18 respectively. The difference in mean values of PPAR was significant ρ<0.05. Conclusion: The levels of PPAR-g in patients with type 2 Diabetes Mellitus and Obese cases are significantly lower than normal controls. (author)

Full Text Available Background: Severe metabolic acidosis occurs during orthotopic liver transplantation (OLT particularly during the anhepatic phase. Although NaHCO3 is considered as the current standard therapy, there are numerous adverse effects. The aim of this study was to determine whether the restricted use of normal saline during anesthesia could reduce the need for NaHCO3. Methods: In this study we enrolled 75 patients with end-stage liver disease who underwent OLT from February 2010 until September 2010 at the Shiraz Organ Transplantation Center. Fluid management of two different transplant anesthetics were compared. The effect of restricted normal saline fluid was compared with non-restricted normal saline fluid on hemodynamic and acid-base parameters at three times during OLT: after the skin incision (T1, 15 min before reperfusion (T2, and 5 min after reperfusion (T3. Results: There were no significant differences in demographic characteristics of the donors and recipients (P>0.05. In the restricted normal saline group there was significantly lower central venous pressure (CVP than in the non-restricted normal saline group (P=0.002. No significant differences were noted in the other hemodynamic parameters between the two groups (P>0.05. In the non-restricted normal saline group arterial blood pH (P=0.01 and HCO3 (P=0.0001 were significantly less than the restricted normal saline group. The NaHCO3 requirement before reperfusion was significantly more than with the restricted normal saline group (P=0.001. Conclusion: Restricted normal saline administration during OLT reduced the severity of metabolic acidosis and the need for NaHCO3 during the anhepatic phase.

Caffeine Improves Basketball Performance in Experienced Basketball Players
Puente, Carlos; Areces, Francisco
2017-01-01
The aim of this study was to determine the effect of caffeine intake on overall basketball performance in experienced players. A double-blind, placebo-controlled, randomized experimental design was used for this investigation. In two different sessions separated by one week, 20 experienced basketball players ingested 3 mg of caffeine/kg of body mass or a placebo. After 60 min, participants performed 10 repetitions of the following sequence: Abalakov jump, Change-of-Direction and Acceleration Test (CODAT) and two free throws. Later, heart rate, body impacts and game statistics were recorded during a 20-min simulated basketball game. In comparison to the placebo, the ingestion of caffeine increased mean jump height (37.3 ± 6.8 vs. 38.2 ± 7.4 cm; p = 0.012), but did not change mean time in the CODAT test or accuracy in free throws. During the simulated game, caffeine increased the number of body impacts (396 ± 43 vs. 410 ± 41 impacts/min; p basketball players. PMID:28925969

Normalized modes at selected points without normalization
Kausel, Eduardo
2018-04-01
As every textbook on linear algebra demonstrates, the eigenvectors for the general eigenvalue problem | K - λM | = 0 involving two real, symmetric, positive definite matrices K , M satisfy some well-defined orthogonality conditions. Equally well-known is the fact that those eigenvectors can be normalized so that their modal mass μ =ϕT Mϕ is unity: it suffices to divide each unscaled mode by the square root of the modal mass. Thus, the normalization is the result of an explicit calculation applied to the modes after they were obtained by some means. However, we show herein that the normalized modes are not merely convenient forms of scaling, but that they are actually intrinsic properties of the pair of matrices K , M, that is, the matrices already "know" about normalization even before the modes have been obtained. This means that we can obtain individual components of the normalized modes directly from the eigenvalue problem, and without needing to obtain either all of the modes or for that matter, any one complete mode. These results are achieved by means of the residue theorem of operational calculus, a finding that is rather remarkable inasmuch as the residues themselves do not make use of any orthogonality conditions or normalization in the first place. It appears that this obscure property connecting the general eigenvalue problem of modal analysis with the residue theorem of operational calculus may have been overlooked up until now, but which has in turn interesting theoretical implications.Á

expressive vocabulary of children with normal and deviant phonological development. to determine whether alterations presented by children with phonological disorders occur only at the phonological level or if there are any impacts on lexical acquisition; to compare the vocabulary performance of children with phonological disorders to reference values presented by the used test. participants of the study were 36 children of both genders, 14 with phonological disorders (Study group) and 22 with typical language development (Control Group). The ABFW - Vocabulary Test (Befi-Lopes, 2000) was used for assessing the expressive vocabulary of children and later to compare the performance of both groups. the performance of children with phonological disorder in the expressive vocabulary test is similar to that of children with normal phonological development. Most of the children of both groups reached the benchmarks proposed by the test for the different semantic fields. The semantic field Places demonstrated to be the most complex for both groups. the alterations presented by children with phonological disorder area limited to the phonological level, having no impact on the lexical aspect of language.

Introduction Not only do transgender female sex workers have some of the highest rates of sexually transmitted infections (STI), human immunodeficiency virus (HIV), and experienced stigma, they also have higher likelihood of early sexual debut and some of the lowest levels of educational attainment compared to other stigmatized populations. Some of the most common interventions designed to reduce transmission of HIV and STIs seek to educate high-risk groups on sexual health and encourage condom use across all partner types; however, reaching stigmatized populations, particularly those in resource-limited settings, is particularly challenging. Considering the importance of condom use in stopping the spread of HIV, the aim of this study was two-fold; first to characterize this hard-to-reach population of transgender female sex workers in the Dominican Republic, and second, to assess associations between their HIV knowledge, experienced stigma, and condom use across three partner types. Methods We analyzed self-reported data from the Questionnaire for Transgender Sex Workers (N = 78). Respondents were interviewed at their workplaces. Univariate and bivariate analyses were employed. Fisher Chi-square tests assessed differences in HIV knowledge and experienced stigma by condom use across partner types. Results HIV knowledge was alarmingly low, condom use varied across partner type, and the respondents in our sample had high levels of experienced stigma. Average age of first sexual experience was 13.12 years with a youngest age reported of 7. Dominican Republic statutory rape laws indicate 18 years is the age of consent; thus, many of these transgender women’s first sexual encounters would be considered forcible (rape) and constitute a prosecutable crime. On average, respondents reported 8.45 sexual partners in the prior month, with a maximum of 49 partners. Approximately two thirds of respondents used a condom the last time they had sex with a regular partner. This

Group Empowerment in Nursing Education.
Friend, Mary Louanne
2015-12-01
Nursing education is experiencing rapid changes, as nurses are expected to transform and lead health care delivery within the United States. The ability to produce exceptional graduates requires faculty who are empowered to achieve goals. The Sieloff-King Assessment of Group Empowerment Within Organizations (SKAGEO) was adapted and administered online to a stratified sample of administrators and faculty in American Association of Colleges of Nursing-member schools. Participants' scores were within high ranges in both empowerment capacity and capability; however, administrator group scores were higher. Data analyses indicated that administrator leadership competencies were associated with group empowerment. This study suggests that empowered faculty and administrator groups anticipate changing health care trends and effect student outcomes and competencies by their interventions. Also, it can be inferred that as a result of administrators' competencies, participants teach in empowered work environments where they can model ideal behaviors. Copyright 2015, SLACK Incorporated.

Full Text Available Purpose: To compare electroretinogram (ERG characteristics in patients with retinitis pigmentosa (RP and normal subjects using frequency domain analysis. Methods: Five basic ERG recordings were performed in normal subjects and patients with a clinical diagnosis of RP according to the ISCEV (International Society of Clinical Electrophysiology of Vision protocol. Frequency domain analysis was performed by MATLAB software. Different frequency domain parameters were compared between the study groups. Results: Peak frequency (Fmod of flicker and oscillatory responses in RP patients showed significant (P<0.0001 high pass response as compared to normal controls. Peak frequency (Fmod of the other responses was not significantly different between the two groups. Conclusion: In addition to conventional ERG using time domain methods, frequency domain analysis may be useful for diagnosis of RP. Oscillatory and flicker responses may be analyzed in frequency domain. Fast Fourier transform may reveal two distinct high pass responses (shift to higher frequencies in Fmod. Time and frequency domain analyses may be performed simultaneously with many modern ERG machines and may therefore be recommended in RP patients.

Objective: To study the relationships between plasma adrenomedullin (ADM) and normal pregnancy and pathogenesis of pregnancy-induced hypertension (PIH). Methods: ADM concentrations in the plasma from 10 normal non-pregnant women, 36 normal pregnant women (12 first, 12 second, 12 third trimester, respectively) and 30 cases of PIH (10 mild, 10 moderate, 10 severe, respectively) were determined by radioimmunoassay, and data were analyzed statistically. Results: ADM concentrations in the first, second and third trimester of normal pregnancy increased significantly than that of normal non-pregnant women (P<0.05). ADM concentration in the plasma of patients with PIH was higher than that of third trimester pregnancy (P<0.01). There were significant differences between mild, moderate, and severe PIH groups (P<0.05). In the PIH groups, significant positive correlation was found between plasma ADM concentration and mean arterial pressure (r=0.822, P<0.05). Incidence of low birth weight infants was related to serious degree of PIH. Conclusion: ADM may involve in maintaining normal human pregnancy. ADM may increase compensatorily in the pathogenesis of PIH

To investigate differences in physical activity and attitude toward physical activity in adolescents with different degrees of overweight and explore whether the prediction of physical activity by attitude is moderated by level of overweight. Subjects were divided into a normal-weight group (n = 37, 18.8 +/- 1.2 kg/m2), an overweight group (n = 28, 25.9 +/- 1.3 kg/m2), and an obese group (n = 24, 33.7 +/- 4.1 kg/m2). Mean age was 14.6 +/- 1.2 years, with 72% girls. Physical activity was estimated using the Baecke Questionnaire. Attitude was measured by assessing perceived benefits and barriers. Participation in sports was higher in normal-weight compared with overweight (p attitude compared with their normal-weight (p attitude was not moderated by level of overweight. This study demonstrates that overweight and obese adolescents show lower sport participation and have a less positive attitude toward physical activity. Interventions in youngsters with weight problems should try to increase participation in sports by making activities more fun and attractive for these youngsters.

Full Text Available Introduction & Objective: High levels of homocystein are a risk factor for insulin resistance, diabetes mellitus and cardio-vascular complications. This study was done to assess serum homocystein and folic acid levels and their relationship in women with gestational diabetes and compare them with normal pregnant women. Materials & Methods: This analytic epidemiologic case-control study was performed in Qazvin Kosar hospital in 2013-2015. 120 singleton pregnant women with 24-28 weeks of gestation according to 2-hour 75g oral glucose tolerance test were assigned to two groups; gestational diabetes (n=60, and normal pregnancy (n=60. Serum homocystein and folic acid levels were measured in two groups. Data were analyzed with statistical t-test and correlation method. Results: In gestational diabetes serum homocystein level was significantly higher (P<0.001 and folic acid was significantly lower (P<0.001 than normal pregnancy group .No relation-ship was observed between serum homocystein and serum folate. In both groups, serum folic acid was significantly related to fasting blood sugar. This relationship was inverse in gesta-tional diabetes group (P<0.001, r = - 0.512 and direct in normal pregnancy group (P=0.001 r =0.417. Conclusion: It seems folic acid has a role in regulation of serum homocystein level and blood sugar.(Sci J Hamadan Univ Med Sci 2015; 22 (2: 93-98

Experienced physicians benefit from analyzing initial diagnostic hypotheses
Directory of Open Access Journals (Sweden)
Adam Bass
2013-03-01
Full Text Available Background: Most incorrect diagnoses involve at least one cognitive error, of which premature closure is the most prevalent. While metacognitive strategies can mitigate premature closure in inexperienced learners, these are rarely studied in experienced physicians. Our objective here was to evaluate the effect of analytic information processing on diagnostic performance of nephrologists and nephrology residents. Methods: We asked nine nephrologists and six nephrology residents at the University of Calgary and Glasgow University to diagnose ten nephrology cases. We provided presenting features along with contextual information, after which we asked for an initial diagnosis. We then primed participants to use either hypothetico-deductive reasoning or scheme-inductive reasoning to analyze the remaining case data and generate a final diagnosis. Results: After analyzing initial hypotheses, both nephrologists and residents improved the accuracy of final diagnoses (31.1% vs. 65.6%, p < 0.001, and 40.0% vs. 70.0%, p < 0.001, respectively. We found a significant interaction between experience and analytic processing strategy (p = 0.002: nephrology residents had significantly increased odds of diagnostic success when using scheme-inductive reasoning (odds ratio [95% confidence interval] 5.69 [1.59, 20.33], p = 0.007, whereas the performance of experienced nephrologists did not differ between strategies (odds ratio 0.57 [0.23, 1.39], p = 0.2. Discussion: Experienced nephrologists and nephrology residents can improve their performance by analyzing initial diagnostic hypotheses. The explanation of the interaction between experience and the effect of different reasoning strategies is unclear, but may relate to preferences in reasoning strategy, or the changes in knowledge structure with experience.

Coronary blood flow and diastolic function are well known to interfere with each other through mechanical and metabolic mechanisms. We aimed to assess the relationship between coronary flow reserve (CFR) and diastolic dysfunction in patients suffering from angina but with normal coronary angiography. In 16 patients with chest pain and angiographically normal coronary arteries, CFR was measured using transthoracic echo-Doppler by inducing hyperemia through dipyridamole infusion. Diastolic function (E/A, deceleration time, isovolumetric relaxation time [IVRT], propagation velocity [Vp]) and left ventricular mass were evaluated by means of two-dimensional transthoracic echocardiography. The patients were initially divided into two groups on the grounds of CFR only (ACFR: altered CFR, n = 9; NACFR: unaltered CFR, n = 7). Thereafter they were divided into four groups on the grounds of CFR and diastolic function (NN: normal; AA: altered CFR/diastole; AN: altered CFR/normal diastole; NA: normal CFR/altered diastole). Most of the subjects were scheduled in AA (n = 8) or NA (n = 5) groups, which were taken into consideration for further analysis. Patients were not different regarding various risk factors. ACFR and AA patients were older with normal body weight in comparison with NACFR and NA patients (P relationship between altered CFR and diastole.

In order to prevent the over-representation of young drivers in car crashes, France instated an early driver training from the age of 16, but the positive effects of this opportunity have not yet been proven. Three groups of male drivers (12 subjects each) were confronted with some prototypical accident scenarios introduced in a simulated urban circuit. The first and second groups were composed of young drivers having less than one month of driving licence; twelve have had a traditional learning course, and twelve had followed, in addition to the initial course, an early driver training under the supervision of an adult. The third group was composed of experienced drivers. Strategies of the three groups were analyzed through their response time, speed and maneuvers. No difference appeared across groups regarding obstacle detection. But traditionally-trained drivers' position control was more conservative than the two others groups, which were more likely to involve efficient evasive action. The exposure gained during early training could thus increase the development of visuo-motor coordination and involve better skills in case of difficult situations. Others accidents' scenarios could be used to confront young drivers with difficult situations not commonly encountered in natural driving.

Earing, Christopher Matthew Norton; McKeon, Damian John; Kubis, Hans-Peter
2014-05-01
To investigate the ventilatory response to CO2 in hyperoxia, hypoxia, and during exercise amongst experienced scuba divers and matched controls. Two studies were performed. The first investigated the CO2 sensitivity in rest and exercise using CO2 rebreathing in hyperoxia at a workload typical for diving with divers (n = 11) and controls (n = 11). The second study examined the respiratory drive of divers (n = 10) and controls (n = 10) whilst breathing four different gas mixtures balanced with N2 (ambient air; 25% O2/6% CO2; 13% O2; 13% O2/6% CO2) to assess the combined response to hypercapnia and moderate hypoxia. Exercise at a load typical for diving was found to have no effect on the ventilatory sensitivity to CO2 in divers (rest: 1.49 ± 0.33; exercise: 1.22 ± 0.55 [l/min × mmHg(-1)]) and controls (rest: 2.08 ± 0.71; exercise: 2.05 ± 0.98 [l/min × mmHg(-1)]) while differences in sensitivity remained between the groups. Inhalation of the four gas mixtures revealed the tested oxygen pressures caused no significant alteration in the ventilatory sensitivity to CO2 in divers and controls. Experienced divers possess a lower ventilatory response to CO2 which was not affected by exercise or the tested oxygen pressures suggesting a dominant adaptation of central CO2 sensitivity.

To show the causal relationship between normal walking after various lateral ankle ligament (LAL) injuries caused by acute inversion ankle sprains and alterations in ankle joint contact characteristics, finite element simulations of normal walking were carried out using an intact ankle joint model and LAL injury models. A walking experiment using a volunteer with a normal ankle joint was performed to obtain the boundary conditions for the simulations and to support the appropriateness of the simulation results. Contact pressure and strain on the talus articular cartilage and anteroposterior and mediolateral translations of the talus were calculated. Ankles with ruptured anterior talofibular ligaments (ATFLs) had a higher likelihood of experiencing increased ankle joint contact pressures, strains and translations than ATFL-deficient ankles. In particular, ankles with ruptured ATFL + calcaneofibular ligaments and all ruptured ankles had a similar likelihood as the ATFL-ruptured ankles. The push off stance phase was the most likely situation for increased ankle joint contact pressures, strains and translations in LAL-injured ankles.

Transgenerational soil-mediated differences between plants experienced or naïve to a grass invasion.
Deck, Anna; Muir, Adrianna; Strauss, Sharon
2013-10-01
Invasive species may undergo rapid change as they invade. Native species persisting in invaded areas may also experience rapid change over this short timescale relative to native populations in uninvaded areas. We investigated the response of the native Achillea millefolium to soil from Holcus lanatus-invaded and uninvaded areas, and we sought to determine whether differential responses between A. millefolium from invaded (invader experienced) and uninvaded (invader naïve) areas were mediated by soil community changes. Plants grown from seed from experienced and naïve areas responded differently to invaded and uninvaded soil with respect to germination time, biomass, and height. Overall, experienced plants grew faster and taller than their naïve counterparts. Naïve native plants showed negative feedbacks with their home soil and positive feedbacks with invaded soil; experienced plants were less responsive to soil differences. Our results suggest that native plants naïve to invasion may be more sensitive to soil communities than experienced plants, consistent with recent studies. While differences between naïve and experienced plants are transgenerational, our design cannot differentiate between differences that are genetically based, plastic, or both. Regardless, our results highlight the importance of seed source and population history in restoration, emphasizing the restoration potential of experienced seed sources.

Highlights: ► Spermatogenesis is closely associated with the balance between germ cells proliferation and apoptosis. ► Numerous studies have documented the direct action of ghrelin in the modulation of apoptosis in different cell types. ► Ghrelin may be considered as a modulator of spermatogenesis in normal adult rats. ► Ghrelin may be potentially implicated for abnormal spermatogenesis in some testicular germ cell tumors. -- Abstract: Under normal condition in the most mammals, spermatogenesis is closely associated with the balance between germ cells proliferation and apoptosis. The present study was designed to determine the effects of ghrelin treatment on in vivo quality and quantity expression of apoptosis and proliferation specific indices in rat testicular germ cells. Twenty eight adult normal rats were subdivided into equal control and treatment groups. Treatment group received 3 nmol of ghrelin as subcutaneous injection for 30 consecutive days or vehicle to the control animals. The rats from each group (n = 7) were killed on days 10 and 30 and their testes were taken for immunocytochemical evaluation and caspase-3 assay. Immunohistochemical analysis indicated that the accumulations of Bax and PCNA peptides are generally more prominent in spermatocytes and spermatogonia of both groups. Likewise, the mean percentage of immunoreactive spermatocytes against Bax increased (P 0.05). Upstream of Bax substance parallel to down-regulation of PCNA demonstrate that ghrelin may prevent massive accumulation of germ cells during normal spermatogenesis. These observations also indicate that ghrelin may be considered as a modulator of spermatogenesis in normal adult rats and could be potentially implicated for abnormal spermatogenesis in some testicular germ cell tumors.

Aim: To assess reproducibility of estimating gestational age (GA) of foetus using femur length (FL), biparietal diameter (BPD) and abdominal circumference (AC) within experienced and inexperienced sonographers and between the two. Patients and methods: Two sets of GA estimates each were obtained for FL, BPD and AC by the two observers in 20 normal singleton foetuses. The first estimates for the three biometric parameters were made by the experienced sonographer. Subsequently, the inexperienced sonographer, blind to the estimates of the first observer obtained his own estimates for the same biometric parameters. After a time interval of ten minutes the process was repeated for the second set of GA estimates. All the gestational age estimates were made following standard protocol. Statistical analysis was performed by Pearson's and intraclass correlations, coefficient of variation and Bland–Altman plots. Statistical inferences were drawn at p < 0.05. Results: The Pearson's and intraclass correlations of between GA estimates within and between both observers from measurement of FL, BPD and AC were very high and statistically significant (p < 0.05). Coefficient of variation for duplicate measurements for GA estimates within observers and between observers were quite negligible. Between observers, the first and second GA estimates from FL measurements showed the least variation. Estimates from BPD and AC measurements showed greater degree of variation between the observers. Conclusion: Reproducibility of GA estimation using FL, BPD and AC within experienced and inexperienced sonographers and between the two was excellent. Therefore, a fresh Nigerian radiography graduate with adequate exposure in obstetric ultrasound can correctly determine the gestational age of foetus in routine obstetric ultrasound without supervision

Hyperreactio luteinalis is an unusual condition in which, during pregnancy, both ovaries are enlarged by multiple theca lutein cysts that produce a high level of testosterone. Several weeks postpartum, the cysts resolve and testosterone level returns to normal. Two case studies are presented in which mothers with gestational ovarian theca lutein cysts experienced delayed lactogenesis II. The elevated testosterone at the time of birth suppressed milk production. Once the testosterone level dropped to approximately 300 ng/dL, milk production began. After the initial delay, both mothers breastfed their infants without supplementation.

Physics Climate as Experienced by LGBT+ Physicists
Long, Elena
2012-02-01
In 2009, Elena Long created the LGBT+ Physicists website (http://lgbtphysicists.x10hosting.com) as a warehouse for resources useful for sexual and gender minorities working in physics. This resource has grown to include networking resources, lists of LGBT-friendly universities and localities, recommendations for enacting positive change in physics communities, and out-reach to other STEM-oriented LGBT organizations. This has been possible in large part by the dynamic community of LGBT+ physicists and allies looking to make physics more welcoming towards our community. In 2011, Elena used hir position as Member at Large on the executive committee of the Forum of Graduate Student Affairs (FGSA) to conduct a climate survey that included, among other things, the first serious look at LGBT+ demographics in physics. The survey focused particularly on issues of language heard and harassment experienced by physicists and was broken down into categories based on race, physical and mental ability, gender, and sexuality. Furthermore, it examined the outcomes of experienced harassment and the reasons for when harassment was not reported. Due to the nature of the study, overlapping demographics, especially ``multiple minorities,'' were also explored. This talk will give a brief history of the LGBT+ Physicists resource as well as an overview of the FGSA study.

Purpose: To determine how chemotherapy agents affect radiation dose parameters that correlate with acute hematologic toxicity (HT) in patients treated with pelvic intensity modulated radiation therapy (P-IMRT) and concurrent chemotherapy. Methods and Materials: We assessed HT in 141 patients who received P-IMRT for anal, gynecologic, rectal, or prostate cancers, 95 of whom received concurrent chemotherapy. Patients were separated into 4 groups: mitomycin (MMC) + 5-fluorouracil (5FU, 37 of 141), platinum ± 5FU (Cis, 32 of 141), 5FU (26 of 141), and P-IMRT alone (46 of 141). The pelvic bone was contoured as a surrogate for pelvic bone marrow (PBM) and divided into subsites: ilium, lower pelvis, and lumbosacral spine (LSS). The volumes of each region receiving 5-40 Gy were calculated. The endpoint for HT was grade ≥3 (HT3+) leukopenia, neutropenia or thrombocytopenia. Normal tissue complication probability was calculated using the Lyman-Kutcher-Burman model. Logistic regression was used to analyze association between HT3+ and dosimetric parameters. Results: Twenty-six patients experienced HT3+: 10 of 37 (27%) MMC, 14 of 32 (44%) Cis, 2 of 26 (8%) 5FU, and 0 of 46 P-IMRT. PBM dosimetric parameters were correlated with HT3+ in the MMC group but not in the Cis group. LSS dosimetric parameters were well correlated with HT3+ in both the MMC and Cis groups.

The size of the normal spleen was estimated by CT in 153 children, examined with indication unrelated to splenic disease. In each patient the width, thickness, length and volume of the spleen were calculated. Measurements were also normalized to the transverse diameter of the body of the first lumbar vertebra. The spleen underwent significant growth during the first 4 years of life and reached maximum size at the age of 13. There were no differences in splenic volume between boys and girls. Splenic thickness correlated best with normal splenic volume. The strongest correlation was also found between splenic thickness and volume in a group of 45 children with clinically evident splenomegaly. Splenic thickness, an easy-to-use measurement, may be employed in everyday practice to represent splenic volume on CT. (orig.)

Full Text Available Abstract Pacific people in New Zealand are a minority ethnic population identified in national prevalence studies as having the highest risk of developing gambling problems. As earlier studies identified some links between culture and gambling for this population, our study aimed to deepen understanding of these links and their role in explaining the disproportionate gambling harms experienced by Pacific people. To achieve this aim we employed intersectionality as a theoretical framework to explore the culture-gambling intersection for this population group. We analysed data from a subset of focus groups conducted for a broad study of gambling harms in New Zealand. The subset was selected based on the presence of individuals knowledgeable about Pacific people’s gambling behaviours, including staff from Pacific problem gambling treatment services who provided examples from a cultural perspective. We identified themes at a latent level via an interpretive process to identify underlying cultural contexts of gambling harms. Findings indicated that whilst harms experienced by Pacific people were similar to those identified amongst the general population, the cultural contexts in which some harms manifested were complex. This paper contributes to the existing knowledge base about gambling harms for Pacific people in relation to six culture-gambling intersecting themes that emerged from the data: collectivism, gift-giving, gambling-based fundraising, patriarchy, beliefs about blessings, and sports celebrities. Findings are discussed in relation to the current knowledge of gambling and conceptualisations of gambling harm within Pacific communities. Implications for culturally appropriate harm minimisation strategies and prevention interventions for this population are suggested.

To evaluate the ability of participants of a falls prevention programme to set and achieve goals. The study used a prospective longitudinal design and a mixed-methods approach to data collection. Study participants were (1) 220 older adults participating in a 15-week combined exercise and education falls prevention programme and (2) 9 practitioners (3 home-care nurses, 5 community workers, and an exercise physiologist) involved in delivering the programme. Data from goal-setting forms were analyzed, and descriptive statistics were used to determine the number of appropriate goals set and achieved. Data were analyzed according to programme setting (home- or group-based) and whether or not participants were classified as being from a Culturally and Linguistically Diverse (CALD) background in the Australian context. Semi-structured interviews with programme practitioners were thematically analyzed. A total of 144 respondents (n=75 CALD group, n=41 non-CALD group, n=6 CALD home, n=22 non-CALD home) set 178 goals. Only 101 (57%) goals could be evaluated according to achievement, because participants set goals that focused on health state instead of behaviour, set goals not relevant to falls prevention, used inappropriate constructs to measure goal achievement, and either did not review their goals or dropped out of the programme before goal review. Of these 101 goals, 64 were achieved. Practitioners described their own difficulties in understanding the process of setting health behaviour goals along with communication, cultural, and logistic difficulties. Both CALD and non-CALD participants and those participating in both group- and home-based programmes experienced difficulty in setting and achieving goals to facilitate behaviour change for falls prevention. Data suggest that home-based participants had more difficulty in setting goals than their group-based counterparts and, to a lesser extent, that CALD participants experienced more difficulty in setting goals than

The radiological measurement of the interpedicular disease using a routine antero-posterior view of the spine gives important clinical criteria in evaluation of the intraspinal tumor and stenosis of the spinal canal, and aids for diagnosis of the lesions. In 1934 Elsberg and Dyke reported values of interpedicular distance as determined on roentgenograms for spine of white adult, and in 1968 Song prepared normal values of interpedicular distance for Korean adult. The present investigation was undertaken to provide normal interpedicular distance of Korean teenagers. The author observed the antero-posterior films of the spine of 200 normal teenagers which were composed of 100 male and 100 female. The normal values of the interpedicular distance of Korean teenagers were obtained, as well as 90% tolerance range for clinical use. In this statistical analysis, there were noted significant differences between male and female, and each age groups. It was observed that average male measurement were consistently larger than female by about 1 mm and the growth of the spinal canal appeared to be continued.

Microscopic hyperspectral imaging studies of normal and diabetic retina of rats
Institute of Scientific and Technical Information of China (English)
2008-01-01
A microscopic hyperspectral imager was developed based on the microscopic technology and the spectral imaging technology. Some microscopic hyperspectral images of retina sections of the normal, the diabetic, and the treated rats were collected by the new imager. Single-band images and pseudo-color images of each group were obtained and the typical transmittance spectrums were ex-tracted. The results showed that the transmittance of outer nuclear layer cells of the diabetic group was generally higher than that of the normal. A small absorption peak appeared near the 180th band in the spectrum of the diabetic group and this peak weakened or disappeared in the spectrum of the treated group. Our findings indicate that the microscopic hyperspectral images include wealthy information of retina sections which is helpful for the ophthalmologist to reveal the pathogenesis of diabetic reti-nopathy and explore the therapeutic effect of drugs.

Cognitive dissonance in groups: the consequences of disagreement.
Matz, David C; Wood, Wendy
2005-01-01
As L. Festinger (1957) argued, the social group is a source of cognitive dissonance as well as a vehicle for reducing it. That is, disagreement from others in a group generates dissonance, and subsequent movement toward group consensus reduces this negative tension. The authors conducted 3 studies to demonstrate group-induced dissonance. In the first, students in a group with others who ostensibly disagreed with them experienced greater dissonance discomfort than those in a group with others who agreed. Study 2 demonstrated that standard moderators of dissonance in past research--lack of choice and opportunity to self-affirm, similarly reduced dissonance discomfort generated by group disagreement. In Study 3, the dissonance induced by group disagreement was reduced through a variety of interpersonal strategies to achieve consensus, including persuading others, changing one's own position, and joining an attitudinally congenial group.

Full Text Available Introduction: Tinnitus, the perception of the sound in the absence of an external acoustic source, disrupts the daily life 1 out of every 200 adults, yet its physiological basis remains largely a mystery. The generation of tinnitus is commonly linked with the impaired functioning of the outer hair cells (OHC inside the cochlea. Otoacoustic emissions are the objective test used to assess their activity. Objective: The objective of the investigation was to study the features of Distortion product OtoAcoustic emissions (DPOAE in a group of tinnitus patients with normal hearing and to find out whether there is any difference in DPOAE findings in the tinnitus patients with normal hearing and in persons with normal hearing with no complaint of tinnitus. Materials and Methods: The participants consisted of two groups. The subject group consisted of 16 ears of patients, in which 6 subjects were having tinnitus in both ears while 4 subjects were having tinnitus only in one ear. All subjects were aged between 20 to 60 years with complaint of tinnitus with audiometrically normal hearing. Control group was comprised of 16 audiometrically normal hearing ears of persons who were age and gender matched with the subject groups and had no complaint of tinnitus. Both the subject group as well as control group was subjected for DPOAE test. Findings of both the groups were compared using the unpaired t test. Result and conclusion: It was observed that the amplitudes of DPOAE were significantly lower in tinnitus patients than that of persons without complaint of tinnitus, at a frequency of 1281-1560, 5120-6250, 7243-8837 Hz, which imply that decrease of DPOAEs amplitudes may be related to the presence of tinnitus. It can be concluded that there is association between tinnitus and reduced OHC activity which indicate the OHC of cochlea are involved in the generation of tinnitus.

Making Sense of Experienced Teachers’ Interactive Decisions: Implications for Expertise in Teaching
Directory of Open Access Journals (Sweden)
Bahar Gün
2014-01-01
Full Text Available Teachers’ decision making has always been an area of curiosity in many studies related to teachers and teaching. One approach to understanding teachers’ decisions is through the analysis of their reflection-in-action behaviours. This study, based on the premise that one can gain understanding from examining experienced teachers’ classroom performances, focuses on the interactive decisions made by ten experienced language teachers. The study presents the findings of an analysis of similarities in the motivations behind teachers’ interactive decisions, as demonstrated in their verbal reports following the video recorded lesson observations. These findings show that there are both shared pedagogical and affective attributes among participant teachers. These results, and the insight they give into experienced teachers’ decision making are potentially beneficial for all pre-service and practising teachers.

Full Text Available Abstract Background Diagnosing childhood asthma is dependent upon parental symptom reporting but there are problems in the use of words and terms. The purpose of this study was to describe and compare understandings of childhood 'asthma' by mothers from three different ethnic backgrounds who have no personal experience of diagnosing asthma. A better understanding of parents' perceptions of an illness by clinicians should improve communication and management of the illness. Method Sixty-six mothers living in east London describing their ethnic backgrounds as Bangladeshi, white English and black Caribbean were recruited to 9 focus groups. Discussion was semi-structured. Three sessions were conducted with each ethnic group. Mothers were shown a video clip of a boy with audible wheeze and cough and then addressed 6 questions. Sessions were recorded and transcribed verbatim. Responses were compared within and between ethnic groups. Results Each session, and ethnic group overall, developed a particular orientation to the discussion. Some mothers described the problem using single signs, while others imitated the sound or made comparisons to other illnesses. Hereditary factors were recognised by some, although all groups were concerned with environmental triggers. Responses about what to do included 'normal illness' strategies, use of health services and calls for complementary treatment. All groups were concerned about using medication every day. Expectations about the quality of life were varied, with recognition that restrictions may be based on parental beliefs about asthma, rather than asthma itself. Conclusion Information from these focus groups suggests mothers know a great deal about childhood asthma even though they have no personal experience of it. Knowledge of how mothers from these ethnic backgrounds perceive asthma may facilitate doctor – patient communication with parents of children experiencing breathing difficulties.

Metabolomics data normalization with EigenMS.
Directory of Open Access Journals (Sweden)
Yuliya V Karpievitch
Full Text Available Liquid chromatography mass spectrometry has become one of the analytical platforms of choice for metabolomics studies. However, LC-MS metabolomics data can suffer from the effects of various systematic biases. These include batch effects, day-to-day variations in instrument performance, signal intensity loss due to time-dependent effects of the LC column performance, accumulation of contaminants in the MS ion source and MS sensitivity among others. In this study we aimed to test a singular value decomposition-based method, called EigenMS, for normalization of metabolomics data. We analyzed a clinical human dataset where LC-MS serum metabolomics data and physiological measurements were collected from thirty nine healthy subjects and forty with type 2 diabetes and applied EigenMS to detect and correct for any systematic bias. EigenMS works in several stages. First, EigenMS preserves the treatment group differences in the metabolomics data by estimating treatment effects with an ANOVA model (multiple fixed effects can be estimated. Singular value decomposition of the residuals matrix is then used to determine bias trends in the data. The number of bias trends is then estimated via a permutation test and the effects of the bias trends are eliminated. EigenMS removed bias of unknown complexity from the LC-MS metabolomics data, allowing for increased sensitivity in differential analysis. Moreover, normalized samples better correlated with both other normalized samples and corresponding physiological data, such as blood glucose level, glycated haemoglobin, exercise central augmentation pressure normalized to heart rate of 75, and total cholesterol. We were able to report 2578 discriminatory metabolite peaks in the normalized data (p<0.05 as compared to only 1840 metabolite signals in the raw data. Our results support the use of singular value decomposition-based normalization for metabolomics data.

Categorization of common sounds by cochlear implanted and normal hearing adults.
Collett, E; Marx, M; Gaillard, P; Roby, B; Fraysse, B; Deguine, O; Barone, P
2016-05-01
Auditory categorization involves grouping of acoustic events along one or more shared perceptual dimensions which can relate to both semantic and physical attributes. This process involves both high level cognitive processes (categorization) and low-level perceptual encoding of the acoustic signal, both of which are affected by the use of a cochlear implant (CI) device. The goal of this study was twofold: I) compare the categorization strategies of CI users and normal hearing listeners (NHL) II) investigate if any characteristics of the raw acoustic signal could explain the results. 16 experienced CI users and 20 NHL were tested using a Free-Sorting Task of 16 common sounds divided into 3 predefined categories of environmental, musical and vocal sounds. Multiple Correspondence Analysis (MCA) and Hierarchical Clustering based on Principal Components (HCPC) show that CI users followed a similar categorization strategy to that of NHL and were able to discriminate between the three different types of sounds. However results for CI users were more varied and showed less inter-participant agreement. Acoustic analysis also highlighted the average pitch salience and average autocorrelation peak as being important for the perception and categorization of the sounds. The results therefore show that on a broad level of categorization CI users may not have as many difficulties as previously thought in discriminating certain kinds of sound; however the perception of individual sounds remains challenging.

Physical activity may have several benefits for elderly people. However, the risk of falling might prevent this population from showing interest in physical activity. This research was aimed to explore facilitators and barriers to physical activity in older persons who have experienced at least one fall in the past 12 months. This cross sectional study was conducted in 2010-2011, in Tehran, Iran. Using a multistage sampling method a group of elderly people entered into the study. A multi-section questionnaire was used to collect data on demographic information, physical activity level, and different determinants that might influence physical activity. Several statistical tests including linear regression were used to analyze the data. In all, 180 old people from 40 elderly centers (49 men and 131 women) took part in the study. The mean age of participants was 65.9 ± 6.1 years. The result indicated that most participants experienced two or more falls during the last year (54.5%). Those who had more falls significantly scored lower on the Physical Activity Scale for Elderly (p falls, self-reported health and daily living activities. However, we observed inverse association between number of falls and physical activity. Indeed the findings suggest that we should reinforce benefits exist when designing programs to increase physical activity among elderly population.

Currently, 47 million people have dementia, worldwide, often requiring paid care by formal caregivers. Research regarding family caregivers suggests normalization as a model for coping with negative emotional outcomes in caring for a person with dementia (PWD). The study aims to explore whether normalization coping mechanism exists among formal caregivers, reveal differences in its application among cross-cultural caregivers, and examine how this coping mechanism may be related to implementing person-centered care for PWDs. Content analysis of interviews with 20 formal caregivers from three cultural groups (Jews born in Israel [JI], Arabs born in Israel [AI], Russian immigrants [RI]), attending to PWDs. We extracted five normalization modes, revealing AI caregivers had substantially more utterances of normalization expressions than their colleagues. The normalization modes most commonly expressed by AI caregivers relate to the personhood of PWDs. These normalization modes may enhance formal caregivers' ability to employ person-centered care.

A total of 750 teachers from 16 government and non-government schools from areas of contrasted socio-economic status (SES) responded to a questionnaire designed to investigate associations between selected aspects of burnout among teachers working in secondary schools in Victoria, Australia. By comparing high and low burnout groups on biographic, psychological and work pattern variables, differences between teachers experiencing high and low levels of burnout were identified. Multiple regression analyses assessed the relative importance of these variables in accounting for the variance in each of the three burnout subscales. School type was related to perceptions of stress and burnout. Higher levels of burnout were associated with poorer physical health, higher rates of absenteeism, lower self-confidence and more frequent use of regressive coping strategies. Teachers classified as experiencing high levels of burnout attributed most of the stress in their lives to teaching and reported low levels of career commitment and satisfaction. Further, teachers who recorded high levels of burnout were characterised by lower levels of the personality disposition of hardiness, lower levels of social support, higher levels of role stress and more custodial pupil control ideologies than their low-burnout counterparts. Psychological variables were found to be more significant predictors of burnout than biographical variables.

Asylum seekers, refugees and persons without legal status have been reported to experience a range of difficulties when accessing public services and supports in the UK. While research has identified health care barriers to equitable access such as language difficulties, it has not considered the broader social contexts of marginalization experienced through the dynamics of 'othering'. The current study explores health and health care experiences of Somali and Iraqi asylum seekers, refugees and persons without legal status, highlighting 'minoritization' processes and the 'pathologization' of difference as analytical lenses to understand the multiple layers of oppression that contribute to health inequities. For the study, qualitative methods were used to document the lived experiences of asylum seekers, refugees and persons without legal status. Thirty-five in-depth interviews and five focus groups were used to explore personal accounts, reveal shared understandings and enable social, cognitive and emotional understandings of on-going health problems and challenges when seeking treatment and care. A participatory framework was undertaken which inspired collaborative workings with local organizations that worked directly with asylum seekers, refugees and persons without legal status. The analysis revealed four key themes: 1) pre-departure histories and post-arrival challenges; 2) legal status; 3) health knowledges and procedural barriers as well as 4) language and cultural competence. Confidentiality, trust, wait times and short doctor-patient consultations were emphasized as being insufficient for culturally specific communications and often translating into inadequate treatment and care. Barriers to accessing health care was associated with social disadvantage and restrictions of the broader welfare system suggesting that a re-evaluation of the asylum seeking process is required to improve the situation.

Full Text Available During the development of neuroimaging, numerous analyses were performed to identify population differences, such as studies on age, gender, and diseases. Researchers first normalized the brain image and then identified features that represent key differences between groups. In these studies, the question of whether normalization (a pre-processing step widely used in neuroimaging studies reduces the diversity of brains was largely ignored. There are a few studies that identify the differences between individuals after normalization. In the current study, we analyzed brain diversity on an individual level, both qualitatively and quantitatively. The main idea was to utilize brain images for identity authentication. First, the brain images were normalized and registered. Then, a pixel-level matching method was developed to compute the identity difference between different images for matching. Finally, by analyzing the performance of the proposed brain recognition strategy, the individual differences in brain images were evaluated. Experimental results on a 150-subject database showed that the proposed approach could achieve a 100% identification ratio, which indicated distinct differences between individuals after normalization. Thus, the results proved that after the normalization stage, brain images retain their main distinguishing information and features. Based on this result, we suggest that diversity (individual differences should be considered when conducting group analysis, and that this approach may facilitate group pattern classification.

When anthropometric methods were introduced into clinical practice to quantify changes in the craniofacial framework, features distinguishing various races/ethnic groups were discovered. To treat congenital or post-traumatic facial disfigurements in members of these groups successfully, surgeons require access to craniofacial databases based on accurate anthropometric measurements. Normative data of facial measurements are indispensable to precise determination of the degree of deviations from the normal. The set of anthropometric measurements of the face in the population studied was gathered by an international team of scientists. Investigators in the country of the given ethnic group, experienced and/or specially trained in anthropometric methods, carried out the measurements. The normal range in each resultant database was then established, providing valuable information about major facial characteristics. Comparison of the ethnic groups' databases with the established norms of the North America whites (NAW) offered the most suitable way to select a method for successful treatment. The study group consisted of 1470 healthy subjects (18 to 30 years), 750 males and 720 females. The largest group (780 subjects, 53.1%) came from Europe, all of them Caucasians. Three were drawn from the Middle-East (180 subjects, 12.2%), five from Asia (300 subjects, 20.4%) and four from peoples of African origin (210 subjects, 14.3%). Their morphological characteristics were determined by 14 anthropometric measurements, 10 of them used already by classic facial artists, Leonardo da Vinci and Albrecht Dürer, complemented by four measurements from the nasal, labio-oral and ear regions. In the regions with single measurements, identical values to NAW in forehead height, mouth width, and ear height were found in 99.7% in both sexes, while in those with multiple measurements, vertical measurements revealed a higher frequency of identical values than horizontal ones. The orbital regions

Reminiscence therapy has the potential to improve quality of life for people with dementia. In recent years reminiscence groups have extended to include family members, but carers' experience of attending joint sessions is undocumented. This qualitative study explored the experience of 18 family carers attending 'Remembering Yesterday Caring Today' groups. Semi-structured interviews were transcribed and subjected to thematic analysis. Five themes were identified: experiencing carer support; shared experience; expectations (met and unmet), carer perspectives of the person with dementia's experience; and learning and comparing. Family carers' experiences varied, with some experiencing the intervention as entirely positive whereas others had more mixed feelings. Negative aspects included the lack of respite from their relative, the lack of emphasis on their own needs, and experiencing additional stress and guilt through not being able to implement newly acquired skills. These findings may explain the failure of a recent trial of joint reminiscence groups to replicate previous findings of positive benefit. More targeted research within subgroups of carers is required to justify the continued use of joint reminiscence groups in dementia care. © The Author(s) 2013.

To determine what information, support, and follow-up were offered to women who had experienced severe maternal morbidity (SMM). The present retrospective case review included patients who experienced SMM (admission to intensive care during pregnancy or up to 42 days postpartum) who had previously been reviewed for potential preventability as part of a nationwide New Zealand study performed between January 1 and December 31, 2014. Data were audited to ascertain documented evidence of an event debrief or explanation; referral to social support and/or mental health services; a detailed discharge letter; and a follow-up appointment with a specialist. Of 257 patients who experienced SMM, 23 (8.9%) were offered all four components of care, 99 (38.5%) an event debrief, 102 (39.7%) a referral to social support and/or mental health services, 148 (57.6%) a detailed discharge letter, and 131 (51.0%) a follow-up appointment. Many women who had experienced SMM did not receive explanatory information about their illness, an offer of psychosocial support, or a follow-up appointment prior to discharge from hospital. It is incumbent on clinicians and the maternity care system to improve these aspects of care for all women experiencing a potentially life-changing SMM event to minimize the risk and burden of long-term mental illness. © 2018 International Federation of Gynecology and Obstetrics.

Objective was to the effects of 0.5% silver nitrate, 20% chloroformic garlic extract and 0.9% normal saline in induction of sclerosing cholangitis in the bile ducts of rabbits. During a 6-months period from April to September 2006 in Shiraz University Laboratory Animal Research Center, we selected 3 equal groups of rabbits. We injected 0.5% silver nitrate, 20% chloroformic garlic extract and 0.9% normal saline into the bile ducts of each group. The animals were euthanized and autopsied after 4 months and the liver and bile ducts were removed and studied histopathologically. Cholangiography was undertaken to evaluate the presence and extent of any sclerosing cholangitis. Animals showed sclerosing cholangitis in silver nitrate group (7 [58%]), one (8%) in chloroformic garlic extract group and one (7%) in normal saline group. The difference between silver nitrate and chloroformic garlic extract groups were statistically significant and similar results were noticed between chloroformic garlic extract and normal saline groups. Twenty percent of chloroformic garlic extract had fewer complications such as sclerosing cholangitis, compared to other materials. (author)

Experiencing Security in Interaction Design
DEFF Research Database (Denmark)
Mathiasen, Niels Raabjerg; Bødker, Susanne
2011-01-01
Security is experienced differently in different contexts. This paper argues that in everyday situations, users base their security decisions on a mix of prior experiences. When approaching security and interaction design from an experience approach, tools that help bring out such relevant...... experiences for design are needed. This paper reports on how Prompted exploration workshops and Acting out security were developed to target such experiences when iteratively designing a mobile digital signature solution in a participatory design process. We discuss how these tools helped the design process...... and illustrate how the tangibility of such tools matters. We further demonstrate how the approach grants access to non-trivial insights into people's security experience. We point out how the specific context is essential for exploring the space between experience and expectations, and we illustrate how people...

Normal vibrations in gallium arsenide
Energy Technology Data Exchange (ETDEWEB)
Dolling, G; Waugh, J L T
1964-07-01
The triple axis crystal spectrometer at Chalk River has been used to observe coherent slow neutron scattering from a single crystal of pure gallium arsenide at 296{sup o}K. The frequencies of normal modes of vibration propagating in the [{zeta}00], ({zeta}{zeta}{zeta}], and (0{zeta}{zeta}] crystal directions have been determined with a precision of between 1 and 2{center_dot}5 per cent. A limited number of normal modes have also been studied at 95 and 184{sup o}K. Considerable difficulty was experienced in obtaining welt resolved neutron peaks corresponding to the two non-degenerate optic modes for very small wave-vector, particularly at 296{sup o}K. However, from a comparison of results obtained under various experimental conditions at several different points in reciprocal space, frequencies (units 10{sup 12} c/s) for these modes (at 296{sup o}K) have been assigned: T 8{center_dot}02{+-}0{center_dot}08 and L 8{center_dot}55{+-}02. Other specific normal modes, with their measured frequencies are (a) (1,0,0): TO 7{center_dot}56 {+-} 008, TA 2{center_dot}36 {+-} 0{center_dot}015, LO 7{center_dot}22 {+-} 0{center_dot}15, LA 6{center_dot}80 {+-} 0{center_dot}06; (b) (0{center_dot}5, 0{center_dot}5, 0{center_dot}5): TO 7{center_dot}84 {+-} 0{center_dot}12, TA 1{center_dot}86 {+-} 0{center_dot}02, LO 7{center_dot}15 {+-} 0{center_dot}07, LA 6{center_dot}26 {+-} 0{center_dot}10; (c) (0, 0{center_dot}65, 0{center_dot}65): optic 8{center_dot}08 {+-}0{center_dot}13, 7{center_dot}54 {+-} 0{center_dot}12 and 6{center_dot}57 {+-} 0{center_dot}11, acoustic 5{center_dot}58 {+-} 0{center_dot}08, 3{center_dot}42 {center_dot} 0{center_dot}06 and 2{center_dot}36 {+-} 004. These results are generally slightly lower than the corresponding frequencies for germanium. An analysis in terms of various modifications of the dipole approximation model has been carried out.

The need for effective training methods for enhancing cognitive-behavioural therapist competency is not only relevant to new therapists but also to experienced therapists looking to retain and further enhance their skills. Self-practice/self-reflection (SP/SR) is a self-experiential cognitive-behavioural therapy (CBT) training programme, which combines the experience of practicing CBT methods on oneself with structured reflection on the implications of the experience for clinical practice. In order to build on previous qualitative studies of SP/SR, which have mainly focused on trainee CBT therapists, the aim of the current study was to quantify the impact of SP/SR on the therapeutic skills of an experienced cohort of CBT therapists. Fourteen CBT therapists were recruited to participate in an SP/SR programme specifically adapted for experienced therapists. In the context of a quasi-experimental design including multiple baselines within a single-case methodology, therapists provided self-ratings of technical cognitive therapy skill and interpersonal empathic skill at four critical time points: baseline, pre-SP/SR and post-SP/SR and follow-up. Analysis of programme completers (n = 7) indicated that SP/SR enhances both technical skill and interpersonal therapeutic skill. Further intention-to-treat group (n = 14) analyses including both those who left the programme early (n = 3) and those who partially completed the programme (n = 4) added to the robustness of findings with respect to technical cognitive therapy skills but not interpersonal empathic skills. It was concluded that SP/SR, as a training and development programme, could offer an avenue to further therapeutic skill enhancement in already experienced CBT therapists.

Competition in human groups-Impact on group cohesion, perceived stress and outcome satisfaction.
Boos, Margarete; Franiel, Xaver; Belz, Michael
2015-11-01
This study on competition in human groups was performed within the context of the competitive outcome interdependence concept: the degree to which personal outcomes among group members are affected by the consequences of task performance of others, e.g. when one group member gains a high reward for a task, this lowers the available reward for other group members. Our computer-based multi-participant game empirically assessed how competitive versus neutral conditions influenced the reward-maximising behaviour of 200 undergraduate students functioning in ten-person groups - each playing two games (1 neutral and 1 competitive), their perceived pay satisfaction as well as perceived stress levels and sense of calmness within the games' task to search for coins. Participants were represented by black dots moving on a virtual playground. Results showed that competition led to reward-maximising but fellow group member disadvantaging behaviour, and all participants experienced lower pay satisfaction, higher stress levels and less calmness. We conclude that short-term behavioural consequences of positive individual competitive behaviour were gained at the above-mentioned potential long-term negative costs for all group members. This implies group paradigms aimed at sustainability should avoid introducing competitive factors that at best result in short-lived gains and at worst cause widespread dissatisfaction, stress and a pervasive lack of calmness.

Proportional and functional analogical reasoning in normal and language-impaired children.
Nippold, M A; Erskine, B J; Freed, D B
1988-11-01
Teachers often use analogies in classroom settings to clarify new concepts for their students. However, analogies may inadvertently confuse the youngster who has difficulty identifying the one-to-one comparisons underlying them. Although analogical reasoning has been studied extensively in normal children, no information was available concerning this construct in children having a specific language impairment. Thus, it was unknown to what extent they might be deficient in analogical reasoning. Therefore, in the present study, 20 children ages 6-8 years (mean age = 7:6) having normal nonverbal intelligence but deficits in language comprehension were administered tasks of verbal and perceptual proportional analogical reasoning and a problem-solving task of functional analogical reasoning. Compared to a normal-language control group matched on the basis of chronological age and sex, the language-impaired group was deficient in all three tasks of analogical reasoning. However, when the factor of nonverbal intelligence was controlled statistically, the differences between the groups on each of the tasks were removed. Additional findings were that verbal proportional analogical reasoning was significantly correlated to perceptual proportional analogical reasoning and to functional analogical reasoning. Implications for assessment and intervention with young school-age language-impaired children are discussed.

Persistent Drug-Induced Parkinsonism in Patients with Normal Dopamine Transporter Imaging.
Directory of Open Access Journals (Sweden)
Jin Yong Hong
Full Text Available Functional neuroimaging for the dopamine transporter (DAT is used to distinguish drug-induced parkinsonism (DIP from subclinical Parkinson's disease (PD. Although DIP patients who show a normal DAT image are expected to recover completely, some do not. We investigated whether these patients showed changes in striatal DAT activity using semi-quantitative analysis of 18F-FP-CIT PET data. DIP patients with visually normal DAT images were selected from medical records. The subjects were classified as patients who recovered partially (PR or completely within 12 months (CR. The 18F-FP-CIT uptake in each striatal subregion was compared between the CR and the PR groups. In total, 41 and 9 patients of the CR and PR groups were assessed, respectively. The two patient groups were comparable in terms of clinical characteristics including age, sex, and severity of parkinsonism. From semi-quantitative analysis of the PET image, the PR patients showed a relatively lower ligand uptake in the ventral striatum, the anterior putamen and the posterior putamen compared with the CR patients. This result suggests that persistent DIP in patients with visually normal DAT imaging may be associated with subtle decrement of DAT activity.

Normal pressure hydrocephalus (NPH) remains most often a clinical diagnosis and has been widely considered responsive to the placement of a cerebrospinal fluid (CSF) shunt. The high incidence of patients with Alzheimer's disease (AD) with NPH symptoms leads to poorer outcomes than would be expected in patients with NPH alone. This article reviews a series of patients operated on for presumed NPH in whom preoperative high-volume lumbar puncture (HVLP) and intraoperative cortical brain biopsies were performed. The data derived from these procedures were then used to understand the incidence of AD in patients presenting with NPH symptoms and to analyze the efficacy of HVLP in patients with NPH and patients with concurrent AD (NPH+AD). A review of the outcomes of shunt surgery is provided. The cases of all patients who underwent placement of a CSF shunt for NPH from 1998 to 2013 at the University of Virginia by the senior author were retrospectively reviewed. Patients who underwent HVLP and patients who underwent cortical brain biopsies were stratified based on the biopsy results into an NPH-only group and an NPH+AD group. The HVLP results and outcomes were then compared in these 2 groups. From 1998 to 2013, 142 patients underwent shunt operations because of a preoperative clinical diagnosis of NPH. Of the patients with a shunt who had a diagnosis of NPH, 105 (74%) received HVLPs. Of 142 shunt-treated patients with NPH, 27 (19%) were determined to have concomitant Alzheimer's pathology based on histopathological findings at the time of shunting. Patients who underwent repeat biopsies had an initial positive outcome. After they clinically deteriorated, they underwent repeat biopsies during shunt interrogation, and 13% of the repeat biopsies demonstrated Alzheimer's pathology. Improvements in gait and cognition did not reach significance between the NPH and NPH+AD groups. In total, 105 patients underwent HVLP before shunt placement. In the NPH cohort, 44.6% of patients

Purpose: Vestibular schwannomas (VS) are increasingly diagnosed in patients with normal hearing because of advances in magnetic resonance imaging. We sought to evaluate whether stereotactic radiosurgery (SRS) performed earlier after diagnosis improved long-term hearing preservation in this population. Methods and Materials: We queried our quality assessment registry and found the records of 1134 acoustic neuroma patients who underwent SRS during a 15-year period (1997-2011). We identified 88 patients who had VS but normal hearing with no subjective hearing loss at the time of diagnosis. All patients were Gardner-Robertson (GR) class I at the time of SRS. Fifty-seven patients underwent early (≤2 years from diagnosis) SRS and 31 patients underwent late (>2 years after diagnosis) SRS. At a median follow-up time of 75 months, we evaluated patient outcomes. Results: Tumor control rates (decreased or stable in size) were similar in the early (95%) and late (90%) treatment groups (P=.73). Patients in the early treatment group retained serviceable (GR class I/II) hearing and normal (GR class I) hearing longer than did patients in the late treatment group (serviceable hearing, P=.006; normal hearing, P<.0001, respectively). At 5 years after SRS, an estimated 88% of the early treatment group retained serviceable hearing and 77% retained normal hearing, compared with 55% with serviceable hearing and 33% with normal hearing in the late treatment group. Conclusions: SRS within 2 years after diagnosis of VS in normal hearing patients resulted in improved retention of all hearing measures compared with later SRS.

Differences in dietary patterns between overweight and normal-weight adolescents.
Jodkowska, Maria; Oblacińska, Anna; Tabak, Izabela; Radiukiewicz, Katarzyna
2011-01-01
To investigate the differences in the dietary patterns of Polish overweight and normal weight adolescents. The study was carried out on a group of 1906 pupils from gymnasium (lower secondary school) aged 13-15 years, of whom 953 were overweight and 953 had normal body mass. The sample was taken from a representative group of 8386 pupils. Their height and body weight were measured, and their BMI was calculated. Overweight was defined as BMI ł85 percentile for gender and age. Using the method of "selection in pairs", each overweight pupil was paired with a pupil with normal body weight. The research tool was a self-reported questionnaire, containing questions regarding how often selected food products were usually consumed during the week, how regularly basic meals (breakfast, lunch, supper) were eaten, and data on snacking. Overweight adolescents consumed unhealthy products such as sweets and crisps significantly less often than their peers with appropriate body mass. Overweight girls ate dark bread significantly more often, and consumed soft drinks less often than their peers with normal weight. Overweight adolescents had more irregular meals than those with normal weight: only 44% overweight adolescents had breakfast every day, significantly less than adolescents with normal weight. Nevertheless, overweight teenagers snacked significantly less often than young people with normal body mass. The overweight teenagers also less often chose snacks with high fat content, sugar and salt, and more often vegetables, fruits, as well as yoghurt and kefir. 1. Our study shows that compliance of low energy diet alone does not ensure the maintenance of normal body weight. Irregularity of meals and breakfast skipping play an important role in developing overweight and obesity in adolescents. 2. In future studies on dietary patterns in a larger sample of adolescents, emphasis should be placed on adding questions about portion size, food preparation and meal time. Eating

Full Text Available In this communication, we report the results of a preliminary neutron diffraction investigation of iron meteorites. These planetary materials are mainly constituted by metallic iron with variable nickel contents, and, owing to their peculiar genesis, are considered to offer the best constrains on the early stages of planetary accretion. Nine different iron meteorites, representative of different chemical and structural groups, thought to have been formed in very different pressure and temperature conditions, were investigated, evidencing variances in crystallites size, texturing, and residual strain. The variability of these parameters and their relationship, were discussed in respect to possible diverse range of petrological conditions, mainly pressure and cooling rate, experienced by these materials during the crystallization stage and/or as consequence of post accretion events.

The workshop of 26-27 june 2000, on nuclear power Plant LIfe Management (PLIM), also included working groups in which major issues facing PLIM activities for nuclear power plants were identified and discussed. The third group was on Business. The discussion concerned the following points: There are concerns about retaining experienced/trained personnel, and maintaining a good working relationship among them, as well as about the closure of research facilities, the reduction in staff numbers under increasing economic pressure and the lack of new nuclear power plant constructions. The marginal cost of producing electricity is lower for most existing nuclear power plants than for almost all other energy sources. Refurbishment costs are usually relatively small compared with new investments. The ongoing regulatory reform of the electricity market will bring increasing competition. Although PLIM has been carried out in many countries with favourable results, there are still uncertainties which affect business decisions regarding financial and market risks in PLIM activities. Recommendations were made. (author)

2017-05-01
This study explored the perceptions of fatherhood held by 11 men living in a homeless shelter. Using consensual qualitative research methodology (CQR; Hill, 2012), we investigated perceptions of masculinity and fatherhood among fathers experiencing homelessness. Participants described (a) their perceptions of masculinity and fatherhood and changes resulting from homelessness, (b) physical and psychological challenges of being a father experiencing homelessness, and (c) expectations of homeless fathers. The fathers generally expressed feelings of low self-esteem related to their perceived difficulty fulfilling the role of providers for their family; however, they also adapted their view of fatherhood to include roles suited to their situation, such as that of guide, teacher, and role model. Suggestions are made for clinicians in helping fathers navigate and develop these roles, and limitations and directions for future research are discussed.

Experiencing Physical Pain Leads to More Sympathetic Moral Judgments
Xiao, Qianguo; Zhu, Yi; Luo, Wen-bo
2015-01-01
Previous studies have shown that observing another’s pain can evoke other-oriented emotions, which instigate empathic concern for another’s needs. It is not clear whether experiencing first-hand physical pain may also evoke other-oriented emotion and thus influence people’s moral judgment. Based on the embodied simulation literature and neuroimaging evidence, the present research tested the idea that participants who experienced physical pain would be more sympathetic in their moral judgments. Study 1 showed that ice-induced physical pain facilitated higher self-assessments of empathy, which motivated participants to be more sympathetic in their moral judgments. Study 2 confirmed findings in study 1 and also showed that State Perspective Taking subscale of the State Empathy Scale mediated the effects of physical pain on moral judgment. These results provide support for embodied view of morality and for the view that pain can serve a positive psychosocial function. PMID:26465603

Do in-car devices affect experienced users' driving performance?
Directory of Open Access Journals (Sweden)
Allert S. Knapper
2015-07-01
Full Text Available Distracted driving is considered to be an important factor in road safety. To investigate how experienced user's driving behaviour is affected by in-vehicle technology, a fixed-base driving simulator was used. 20 participants drove twice in a rich simulated traffic environment while performing secondary, i.e. mobile phone and navigation system tasks. The results show that mean speed was lower in all experimental conditions, compared to baseline driving, while subjective effort increased. Lateral performance deteriorated only during visual–manual tasks, i.e. texting and destination entry, in which the participants glanced off the forward road for a substantial amount of time. Being experienced in manipulating in-car devices does not solve the problem of dual tasking when the primary task is a complex task like driving a moving vehicle. The results and discussion may shed some light on the current debate regarding phone use hazards.

Social Role Valorization: A Proposed New Term for the Principle of Normalization
Wolfensberger, Wolf
2011-01-01
The highest goal of the principle of normalization has recently been clarified to be the establishment, enhancement, or defense of the social role(s) of a person or group, via the enhancement of people's social images and personal competencies. In consequence, it is proposed that normalization be henceforth called "social role valorization."

To compare the ability of an experimental antibacterial self-etching primer adhesive system to seal exposure sites in normal, caries-affected and caries-infected human dentin. 30 extracted human third molars were used within 1 month of extraction. 10 intact normal teeth comprised the normal group. 20 teeth with occlusal caries that radiographically extended halfway to the pulp were excavated using caries-detector solution (CDS) and a #4 round carbide bur in a slowspeed handpiece. Half of those teeth were fully excavated free of CDS-stained material without exposing the pulp, and were designated as the caries-affected dentin group. The remaining 10 teeth were excavated as close to the pulp as possible without obtaining an exposure, but whose dentin continued to stain red with CDS; this group was designated as the caries-infected dentin group. The remaining dentin thickness in all of the specimens in the other two groups was then reduced to the same extent as the caries-infected group. Direct exposures of the pulp chamber were made with a 1/4 round bur in the normal dentin or a 25 gauge needle in the other two groups. After measuring the fluid flow through the exposure, the sites were then sealed with an experimental antibacterial fluoride-containing self-etching primer adhesive systems (ABF). Fluid conductance was remeasured every week for 16 weeks. The fluid conductance through the exposure fell 99% in all groups following resin sealing. The seals of normal and caries-affected dentin remained relatively stable over the 16 weeks, while the seals of caries-infected dentin gradually deteriorated, reaching significance at 8 weeks. TEM examination revealed very thin (ca. 0.5 mm) hybrid layers in normal dentin, 3-4 microm thick hybrid layers in caries-affected dentin and 40 microm thick hybrid layers in caries-infected dentin. The tubules of caries-infected dentin were enlarged and filled with bacteria. Resin tags passed around these bacteria in the top 20-40 microm

Children with sensorineural hearing loss can present with instabilities in postural control, possibly as a consequence of hypoactivity of their vestibular system due to internal ear injury. To assess postural control stability in students with normal hearing (i.e., listeners) and with sensorineural hearing loss, and to compare data between groups, considering gender and age. This cross-sectional study evaluated the postural control of 96 students, 48 listeners and 48 with sensorineural hearing loss, aged between 7 and 18 years, of both genders, through the Balance Error Scoring Systems scale. This tool assesses postural control in two sensory conditions: stable surface and unstable surface. For statistical data analysis between groups, the Wilcoxon test for paired samples was used. Students with hearing loss showed more instability in postural control than those with normal hearing, with significant differences between groups (stable surface, unstable surface) (ppostural control compared to normal hearing students of the same gender and age.

, recent studies suggested that conventional data normalization procedures may not always be valid, and demonstrated that alternative normalization strategies better allow detection of low magnitude changes. We hypothesized that these alternative normalization procedures would disclose more widespread...... metabolic alterations in de novo PD. METHODS: [18F]FDG PET scans of 26 untreated de novo PD patients (Hoehn & Yahr stage I-II) and 21 age-matched controls were compared using voxel-based analysis. Normalization was performed using gray matter (GM), white matter (WM) reference regions and Yakushev...... normalization. RESULTS: Compared to GM normalization, WM and Yakushev normalization procedures disclosed much larger cortical regions of relative hypometabolism in the PD group with extensive involvement of frontal and parieto-temporal-occipital cortices, and several subcortical structures.

Hilar displacement is one of the significant sign of pulmonary volume change. The hilar height ratio (HHR) is a value that express the normal position of hilum in its hemithorax, and it is calculated by dividing the distance from the hilum to the lung apex by the distance from the hilum to the diaphragm. Displacement of one hilum is usually easy to detect but both are displaced in the same direction especially, recognition is more difficult. Knowledge of normal HHR allows evaluation of hilar positional change even when the relative hilar position are not altered. Normal chest PA views of 275 cases taken at Korea University Hospital during the period of April 1978 to Jun 1979 were analyzed. The right hilum is positioned in lower half of the right hemithorax, while the left hilum is situated in the upper half of left hemithorax. The difference of hilar ratio according to age group is slight, but there is significant difference between right-HHR and left-HHR. The value of right-HHR is 1.28 ± 0.14, the value of left-HHR is 0.88 ± 0.09.

Building on the respective strengths of parent-led and professional-led groups, a parent-professional team leadership model for group interventions was developed and evaluated for families of youths with emotional and behavioral problems. The model was developed based on feedback from 26 parents in focus group sessions and recommendations from mental health professionals in staff meetings. Evaluations of an implementation of the model in a support, empowerment, and education group intervention (S.E.E. group) have demonstrated the usefulness of this approach in work with families of children with behavioral and emotional problems. This article discusses the challenges of instituting the model in an S.E.E. group. It explores how parents and professionals build the team leadership model and the strengths of this approach in working with parents of youths with serious emotional disturbances.

The clinical significance of imitation behaviour (IB) is unclear. The aim of this study was to investigate the prevalence of subtle naïve and obstinate IB in convenience samples of normal elderly, demented, and depressed subjects. Subtle IB was assessed using a protocol constructed ad hoc in 146 patients, consecutively referred to a memory clinic having received an ICD-10 diagnosis of either dementia or depression, and in 241 healthy subjects. The prevalence of IB in the three groups was determined and the association with possible demographic, cognitive, and non-cognitive variables analysed. Subtle naïve IB was frequent in the elderly with dementia, intermediate in the depressed, and rare in the normal elderly except that the latter frequently stretched out their arms. Obstinate IB never occurred in the normal elderly. IB was predicted by none of the variables used. The groups included were convenience samples with the depressed being a small group precluding further distinction of depressive subtypes. Although naïve IB is a frequent clinical feature in the demented, it also accompanies depressive disorders in the elderly. It can be observed as context-specific IB in the normal elderly. Obstinate IB does not occur in the normal elderly. Copyright 2006 John Wiley & Sons, Ltd.

Full Text Available Pythagorean fuzzy sets are highly appealing in dealing with uncertainty as they allow for greater flexibility in regards to the membership and non-membership degrees by extending the set of possible values. In this paper, we propose a multi-criteria group decision-making approach based on the Pythagorean normal cloud. Some cloud aggregation operators are presented in this paper to facilitate the appraisal of the underlying utilities of the alternatives under consideration. The concept and properties of the Pythagorean normal cloud and its backward generation algorithm, aggregation operators and distance measurement are outlined. The proposed approach resembles the TOPSIS technique, which, indeed, considers the symmetry of the distances to the positive and negative ideal solutions. Furthermore, an example from e-commerce is presented to demonstrate and validate the proposed decision-making approach. Finally, the comparative analysis is implemented to check the robustness of the results when the aggregation rules are changed.

Few studies have examined the neuropsychiatric status of patients with dementia and cognitive impairment in the developing world despite the fact that current demographic trends suggest an urgent need for such studies. To assess the level of neuropsychiatric symptoms in community-dwelling individuals with dementia, cognitive impairment no dementia and normal cognition. Subjects were from the Ibadan site of Indianapolis-Ibadan Dementia Project with stable diagnoses of normal cognition, cognitive impairment, no dementia/mild cognitive impairment (CIND/MCI), and dementia. Informants of subjects made ratings on the neuropsychiatric inventory and blessed dementia scale; subjects were tested with the mini mental state examination. One hundred and eight subjects were included in the analytic sample, 21 were cognitively normal, 34 were demented, and 53 were CIND/MCI. The diagnostic groups did not differ in age, per cent female, or per cent with any formal education. The most frequent symptoms among subjects with CIND/MCI were depression (45.3%), apathy (37.7%), night time behavior (28.3%), appetite change (24.5%), irritability (22.6%), delusions (22.6%), anxiety (18.9%), and agitation (17.0%). Depression was significantly more frequent among the CIND/MCI and dementia (44.1%) groups compared with the normal cognition group (9.5%). Distress scores were highest for the dementia group, lowest for the normal cognition group, and intermediate for the CIND/MCI group. Significant neuropsychiatric symptomatology and distress are present among cognitively impaired persons in this community-based study of older adults in this sub-Saharan African country. Programs to assist family members of cognitively impaired and demented persons should be created or adapted for use in developing countries. Copyright © 2012 John Wiley & Sons, Ltd.

Treatment options are limited for HIV-1-infected individuals who have received extensive previous antiretroviral therapy. ETV has shown significant clinical benefits in treatment-experienced HIV-1+ patients with antiretroviral resistance. The aim of this study was to evaluate the effectiveness of ETV plus optimized background regimen in real-life conditions in a cohort of highly HIV-1 antiretroviral-experienced patients. Retrospective cohort of treatment-experienced HIV-1-infected adults with virological failure who started therapy with an ETV-containing regimen. The effectiveness was evaluated using HIV-1 RNA viral load and changes in CD4+ cell count after 48 weeks of treatment. Forty-two patients ≥ 16 years of age were included; 74% were men, and the median age was 45 years (IQR 41-53). All participants had prior non-nucleoside reverse transcriptase inhibitor use (55% nevirapine, 83%, efavirenz, and 28% both). Baseline median HIV-1 RNA viral load was 15,598 copies/mL (IQR 2651-84,175) and CD4+ cell count was 276 cells/mL (IQR 155-436). After 48 weeks of treatment, 90.5% (95% CI 78-96) of patients had HIV-1 RNA viral load treatment to a median of 407 cells/mL (IQR 242-579); p HIV-1 RNA viral load ≥ 100,000 copies/mL (OR 7.6; 95% CI 1.2-44.80; p = 0.025). Our study provides clinically important evidence of the effectiveness and safety of ETV in highly antiretroviral-experienced HIV-1-infected patients.

Imipramine binding (IB) was studied in the blood platelets from normal controls and depressed patients over a 4-year period (1981-1984) to determine if seasonal variation was present in Bmax or KD. Bimonthly variation in the Bmax of IB was found in normal controls studied longitudinally. No such variation was found when individual values from normal controls were examined on a monthly or seasonal basis. Bmax in depressed patients showed a significant seasonal, but not monthly, variation. KD of IB varied in normal controls using monthly or seasonal data, but not in the probably more reliable bimonthly data. These results suggest that IB studies comparing groups of subjects should match groups for season of the year or, for greater accuracy, month of the year

AIM: To study the blood-brain barrier integrity in prehepatic portal hypertensive rats induced by partial portal vein ligation, at 14 and 40 d after ligation when portal pressure is spontaneously normalized. METHODS: Adult male Wistar rats were divided into four groups: Group I: Sham14d , sham operated; Group II: PH14d , portal vein stenosis; (both groups were used 14 days after surgery); Group III: Sham40d, Sham operated and Group IV: PH40d Portal vein stenosis (Groups II and IV used 40 d after surgery). Plasma ammonia, plasma and cerebrospinal fluid protein and liver enzymes concentrations were determined. Trypan and Evans blue dyes, systemically injected, were investigated in hippocampus to study blood-brain barrier integrity. Portal pressure was periodically recorded. RESULTS: Forty days after stricture, portal pressure was normalized, plasma ammonia was moderately high, and both dyes were absent in central nervous system parenchyma. All other parameters were reestablished. When portal pressure was normalized and ammonia level was lowered, but not normal, the altered integrity of blood-brain barrier becomes reestablished. CONCLUSION: The impairment of blood-brain barrier and subsequent normalization could be a mechanism involved in hepatic encephalopathy reversibility. Hemodynamic changes and ammonia could trigger blood-brain barrier alterations and its reestablishment. PMID:16552803

Purpose: Recent research has enhanced our understanding of radiation injury at the molecular-cellular and tissue levels; significant strides have occurred in standardization of adverse event reporting in clinical trials. In response, the International Atomic Energy Agency, through its Division of Human Health and its section for Applied Radiation Biology and Radiotherapy, organized a consultation meeting in Atlanta (October 2, 2004) to discuss developments in radiobiology, normal tissue reactions, and adverse event reporting. Methods and Materials: Representatives from cooperative groups of African Radiation Oncology Group, Curriculo Radioterapeutica Ibero Latino Americana, European Organization for Research and Treatment of Cancer, National Cancer Institute of Canada Clinical Trials Group, Radiation Therapy Oncology Group, and Trans-Tasman Radiation Oncology Group held the meeting discussion. Results: Representatives of major radiotherapy groups/organizations and prominent leaders in radiotherapy discussed current understanding of normal tissue radiobiologic effects, the design and implementation of future clinical and translational projects for normal tissue injury, and the standardization of adverse-event reporting worldwide. Conclusions: The consensus was to adopt NCI comprehensive adverse event reporting terminology and grading system (CTCAE v3.0) as the new standard for all cooperative group trials. Future plans included the implementation of coordinated research projects focusing on normal tissue biomarkers and data collection methods

Normalization in Lie algebras via mould calculus and applications
Paul, Thierry; Sauzin, David
2017-11-01
We establish Écalle's mould calculus in an abstract Lie-theoretic setting and use it to solve a normalization problem, which covers several formal normal form problems in the theory of dynamical systems. The mould formalism allows us to reduce the Lie-theoretic problem to a mould equation, the solutions of which are remarkably explicit and can be fully described by means of a gauge transformation group. The dynamical applications include the construction of Poincaré-Dulac formal normal forms for a vector field around an equilibrium point, a formal infinite-order multiphase averaging procedure for vector fields with fast angular variables (Hamiltonian or not), or the construction of Birkhoff normal forms both in classical and quantum situations. As a by-product we obtain, in the case of harmonic oscillators, the convergence of the quantum Birkhoff form to the classical one, without any Diophantine hypothesis on the frequencies of the unperturbed Hamiltonians.

On the Margins: Noncitizens Caught in Countries Experiencing Violence, Conflict and Disaster

Full Text Available Today, perhaps more than ever, humanitarian crises permeate the lives of millions, triggering increased human movement and repeatedly testing the international community’s capacity to respond. Stakeholders within the international community have recognized that existing legal and institutional frameworks for protecting forced migrants are inadequate to address the diversity of movements and needs. This article examines the situation of noncitizens who are caught in violence, conflict, and disaster, and asserts that they are an at-risk population requiring tailored responses.Recent history has witnessed numerous humanitarian crises in which noncitizens have been among those most seriously affected. With more people than at any other point in history residing outside of their country of origin, the presence of new and sustained eruptions of violence and conflict, and the frequency and intensity of disasters predicted to increase, noncitizens will continue to be caught in countries experiencing crises. Destination countries, as well as origin countries whose citizens are caught in crisis situations abroad, must understand the challenges that noncitizens may encounter in accessing assistance and protection, and must formulate responses to ensure that their needs are adequately accommodated.While both citizens and noncitizens may encounter difficulties in any given humanitarian crisis, research on five recent crises—the Libyan uprising, the Tohoku earthquake, the tsunami and Fukushima nuclear accident in Japan, flooding in Thailand, Hurricane Sandy in the United States, and the on-going conflict in Syria—demonstrates that a range of factors create particular challenges for noncitizens. Factors related to the underlying environment in the country undergoing a crisis and the responses of different actors may exacerbate the vulnerability of noncitizens. Moreover, different groups of noncitizens manifest distinct protection needs due to specific

Full Text Available The purpose of this study was to examine the level of empathy in deaf and hard of hearing (preadolescents compared to normal hearing controls and to define the influence of language and various hearing loss characteristics on the development of empathy.The study group (mean age 11.9 years consisted of 122 deaf and hard of hearing children (52 children with cochlear implants and 70 children with conventional hearing aids and 162 normal hearing children. The two groups were compared using self-reports, a parent-report and observation tasks to rate the children's level of empathy, their attendance to others' emotions, emotion recognition, and supportive behavior.Deaf and hard of hearing children reported lower levels of cognitive empathy and prosocial motivation than normal hearing children, regardless of their type of hearing device. The level of emotion recognition was equal in both groups. During observations, deaf and hard of hearing children showed more attention to the emotion evoking events but less supportive behavior compared to their normal hearing peers. Deaf and hard of hearing children attending mainstream education or using oral language show higher levels of cognitive empathy and prosocial motivation than deaf and hard of hearing children who use sign (supported language or attend special education. However, they are still outperformed by normal hearing children.Deaf and hard of hearing children, especially those in special education, show lower levels of empathy than normal hearing children, which can have consequences for initiating and maintaining relationships.

Puente, C, Abián-Vicén, J, Areces, F, López, R, and Del Coso, J. Physical and physiological demands of experienced male basketball players during a competitive game. J Strength Cond Res 31(4): 956-962, 2017-The aim of this investigation was to analyze the physical and physiological demands of experienced basketball players during a real and competitive game. Twenty-five well-trained basketball players (8 guards, 8 forwards, and 9 centers) played a competitive game on an outdoor court. Instantaneous running speeds, the number of body impacts above 5 g, and the number of accelerations and decelerations were assessed by means of a 15-Hz global Positioning System accelerometer unit. Individual heart rate was also recorded using heart rate monitors. As a group mean, the basketball players covered 82.6 ± 7.8 m·min during the game with a mean heart rate of 89.8 ± 4.4% of maximal heart rate. Players covered 3 ± 3% of the total distance running at above 18 km·h and performed 0.17 ± 0.13 sprints per minute. The number of body impacts was 8.2 ± 1.8 per minute of play. The running pace of forwards was higher than that of centers (86.8 ± 6.2 vs. 76.6 ± 6.0 m·min; p ≤ 0.05). The maximal speed obtained during the game was significantly higher for guards than that for centers (24.0 ± 1.6 km·h vs. 21.3 ± 1.6 km·h; p ≤ 0.05). Centers performed a lower number of accelerations/decelerations than guards and forwards (p ≤ 0.05). In conclusion, the extraordinary rates of specific movements performed by these experienced basketball players indicate the high physiological demands necessary to be able to compete in this sport. The centers were the basketball players who showed lower physiological demands during a game, whereas there were no differences between guards and forwards. These results can be used by coaches to adapt basketball training programs to the specific demands of each playing position.

Little is known about self-stigma experienced by young people with mental health problems, despite the fact that research has demonstrated its existence. In the present study, we sought to investigate the experiences of self-stigma in childhood and adolescence, and particularly the nature of change in self-stigma across this developmental period. Young adults diagnosed with attention-deficit/hyperactivity disorder (ADHD) or depression before their 18th birthdays were interviewed about their experiences within their peer groups during childhood and adolescence. This qualitative study involved open-ended interviews with 16 young adults aged 18-30 years. Interviews focused on the experience of stigmatization, responses to stigma, and how these changed over time. Three main themes pertaining to self-stigma emerged: (a) being different, (b) peer stigmatization and associated experiences of self-stigma, and (c) selective disclosure and a move toward greater openness. The findings also suggested that the passing of time and changes in young people's social networks and/or degrees of recovery were associated with changes in their experiences of self-stigma. During childhood and adolescence, self-stigma is characterized by a sense of being different from peers and negative self-evaluation as a consequence of that difference. However, our findings also demonstrated that some young people were prepared to challenge the stigma they experienced. Further research is needed to understand the factors that contribute to these differing responses and to develop antistigma interventions that facilitate the inclusion of young people with mental health problems in their peer groups.

On avoiding framing effects in experienced decision makers.
Garcia-Retamero, Rocio; Dhami, Mandeep K
2013-01-01
The present study aimed to (a) demonstrate the effect of positive-negative framing on experienced criminal justice decision makers, (b) examine the debiasing effect of visually structured risk messages, and (c) investigate whether risk perceptions mediate the debiasing effect of visual aids on decision making. In two phases, 60 senior police officers estimated the accuracy of a counterterrorism technique in identifying whether a known terror suspect poses an imminent danger and decided whether they would recommend the technique to policy makers. Officers also rated their confidence in this recommendation. When information about the effectiveness of the counterterrorism technique was presented in a numerical format, officers' perceptions of accuracy and recommendation decisions were susceptible to the framing effect: The technique was perceived to be more accurate and was more likely to be recommended when its effectiveness was presented in a positive than in a negative frame. However, when the information was represented visually using icon arrays, there were no such framing effects. Finally, perceptions of accuracy mediated the debiasing effect of visual aids on recommendation decisions. We offer potential explanations for the debiasing effect of visual aids and implications for communicating risk to experienced, professional decision makers.

The Hybrid cochlear implant (CI), also known as Electro-Acoustic Stimulation (EAS), is a new type of CI that preserves residual acoustic hearing and enables combined cochlear implant and hearing aid use in the same ear. However, 30-55% of patients experience acoustic hearing loss within days to months after activation, suggesting that both surgical trauma and electrical stimulation may cause hearing loss. The goals of this study were to: 1) determine the contributions of both implantation surgery and EAS to hearing loss in a normal-hearing guinea pig model; 2) determine which cochlear structural changes are associated with hearing loss after surgery and EAS. Two groups of animals were implanted (n = 6 per group), with one group receiving chronic acoustic and electric stimulation for 10 weeks, and the other group receiving no direct acoustic or electric stimulation during this time frame. A third group (n = 6) was not implanted, but received chronic acoustic stimulation. Auditory brainstem response thresholds were followed over time at 1, 2, 6, and 16 kHz. At the end of the study, the following cochlear measures were quantified: hair cells, spiral ganglion neuron density, fibrous tissue density, and stria vascularis blood vessel density; the presence or absence of ossification around the electrode entry was also noted. After surgery, implanted animals experienced a range of 0-55 dB of threshold shifts in the vicinity of the electrode at 6 and 16 kHz. The degree of hearing loss was significantly correlated with reduced stria vascularis vessel density and with the presence of ossification, but not with hair cell counts, spiral ganglion neuron density, or fibrosis area. After 10 weeks of stimulation, 67% of implanted, stimulated animals had more than 10 dB of additional threshold shift at 1 kHz, compared to 17% of implanted, non-stimulated animals and 0% of non-implanted animals. This 1-kHz hearing loss was not associated with changes in any of the cochlear measures

Normalization and gene p-value estimation: issues in microarray data processing.

Numerous methods exist for basic processing, e.g. normalization, of microarray gene expression data. These methods have an important effect on the final analysis outcome. Therefore, it is crucial to select methods appropriate for a given dataset in order to assure the validity and reliability of expression data analysis. Furthermore, biological interpretation requires expression values for genes, which are often represented by several spots or probe sets on a microarray. How to best integrate spot/probe set values into gene values has so far been a somewhat neglected problem. We present a case study comparing different between-array normalization methods with respect to the identification of differentially expressed genes. Our results show that it is feasible and necessary to use prior knowledge on gene expression measurements to select an adequate normalization method for the given data. Furthermore, we provide evidence that combining spot/probe set p-values into gene p-values for detecting differentially expressed genes has advantages compared to combining expression values for spots/probe sets into gene expression values. The comparison of different methods suggests to use Stouffer's method for this purpose. The study has been conducted on gene expression experiments investigating human joint cartilage samples of osteoarthritis related groups: a cDNA microarray (83 samples, four groups) and an Affymetrix (26 samples, two groups) data set. The apparently straight forward steps of gene expression data analysis, e.g. between-array normalization and detection of differentially regulated genes, can be accomplished by numerous different methods. We analyzed multiple methods and the possible effects and thereby demonstrate the importance of the single decisions taken during data processing. We give guidelines for evaluating normalization outcomes. An overview of these effects via appropriate measures and plots compared to prior knowledge is essential for the biological

Live theatre as exception and test case for experiencing negative emotions in art.
Goldstein, Thalia R
2017-01-01
Distancing and then embracing constitutes a useful way of thinking about the paradox of aesthetic pleasure. However, the model does not account for live theatre. When live actors perform behaviors perceptually close to real life and possibly really experienced by the actors, audiences may experience autonomic reactions, with less distance, or may have to distance post-experiencing/embracing their emotions.

Unger, S.A.; Hughes, T.

Full text: Myocardial perfusion imaging (MPI) is widely used for risk stratification of patients with known or suspected coronary artery disease. A normal MPI study predicts an annual cardiac event rate of 99 Tc m -Sestamibi (MIBI), omitting the rest study when the post-stress study is interpreted as normal. The safety of this approach has not been validated, all published reports utilising both rest and stress images to interpret a study as 'normal'. Between 1/1/98 and 30/8/98, 489 patients (patients) were referred to our department for stress MPI. Of these, 237 were interpreted as normal on the basis of their post-stress study, and did not undergo a rest study. 12 month clinical follow-up was available in 184 (78%) of these patients, representing the study group (82 males, 102 females; mean age 61±12 years). 156 of these patients were referred for assessment of chest pain, three for dyspnoea, six for abnormal ECGs, and 19 for pre-operative evaluation. At one year of follow-up, there were no myocardial infarcts or admissions for unstable angina, and no cardiac deaths. Three patients died of non-cardiac causes. Seven patients underwent coronary angiography: five were normal, one had a single 50% stenosis, and one had an 80% vein graft stenosis which was subsequently angioplastied. In conclusion, a normal stress MIBI image predicts an excellent prognosis and negates the need for a rest reinjection study, thus reducing patient camera time and radiation exposure, improving departmental throughput, and minimising public health expenditure.

Sensitivity of Raman spectroscopy to normal patient variability
Vargis, Elizabeth; Byrd, Teresa; Logan, Quinisha; Khabele, Dineo; Mahadevan-Jansen, Anita
2011-11-01
Many groups have used Raman spectroscopy for diagnosing cervical dysplasia; however, there have been few studies looking at the effect of normal physiological variations on Raman spectra. We assess four patient variables that may affect normal Raman spectra: Race/ethnicity, body mass index (BMI), parity, and socioeconomic status. Raman spectra were acquired from a diverse population of 75 patients undergoing routine screening for cervical dysplasia. Classification of Raman spectra from patients with a normal cervix is performed using sparse multinomial logistic regression (SMLR) to determine if any of these variables has a significant effect. Results suggest that BMI and parity have the greatest impact, whereas race/ethnicity and socioeconomic status have a limited effect. Incorporating BMI and obstetric history into classification algorithms may increase sensitivity and specificity rates of disease classification using Raman spectroscopy. Studies are underway to assess the effect of these variables on disease.

Sensory information processing and alexithymia are two important factors in determining behavioral reactions. Some studies explain the effect of the sensitivity of sensory processing and alexithymia in the tendency to substance abuse. Giving that, the aim of the current study was to compare the styles of sensory information processing and alexithymia between substance-dependent people and normal ones. The research method was cross-sectional and the statistical population of the current study comprised of all substance-dependent men who are present in substance quitting camps of Masal, Iran, in October 2013 (n = 78). 36 persons were selected randomly by simple randomly sampling method from this population as the study group, and 36 persons were also selected among the normal population in the same way as the comparison group. Both groups was evaluated by using Toronto alexithymia scale (TAS) and adult sensory profile, and the multivariate analysis of variance (MANOVA) test was applied to analyze data. The results showed that there are significance differences between two groups in low registration (P processing and difficulty in describing emotions (P process sensory information in a different way than normal people and show more alexithymia features than them.

To investigate mast cell distribution in normal adult skin to provide a reference range for comparison with mastocytosis. Mast cells (MCs) were counted in uninvolved skin adjacent to basal cell carcinomas and other dermatological disorders in adults. There was an uneven distribution of MCs in different body sites using the anti-tryptase monoclonal antibody technique. Numbers of MCs on the trunk, upper arm, and upper leg were similar, but were significantly different from those found on the lower leg and forearm. Two distinct groups were formed--proximal and distal. There were 77.0 MCs/mm2 at proximal body sites and 108.2 MCs/mm2 at distal sites. Adjusted for the adjacent diagnosis and age, this difference was consistent. The numbers of MCs in uninvolved skin adjacent to basal cell carcinomas and other dermatological disorders were not different from those in the control group. Differences in the numbers of MCs between the distal and the proximal body sites must be considered when MCs are counted for a reliable diagnosis of mastocytosis. A pilot study in patients with mastocytosis underlined the variation in the numbers of MCs in mastocytosis and normal skin, but showed a considerable overlap. The observed numbers of MCs in adults cannot be extrapolated to children. MC numbers varied significantly between proximal and distal body sites and these differences must be considered when MCs are counted for a reliable diagnosis of mastocytosis. There was a considerable overlap between the numbers of MCs in mastocytosis and normal skin.

The aim of this study was to determine whether infiltration of local anesthetics with adrenaline improved septoplasty procedure when compared to normal saline. Eight-two patients undergoing septoplasty were randomized into two groups. In group 1, septal mucoperichondrium was infiltrated with lidocaine with adrenaline, and normal saline was used in group 2. Presence of intra-operative septal mucosal injuries, the amount of bleeding, arterial blood pressure, operation time as well as the quality of the surgical field and the convenience of finding the correct surgical plane as determined by the surgeon using a 5-point scale were compared between two groups. There were no significant differences for the amount of blood loss, mean arterial pressure, operation time, or scores for convenience of finding the correct surgical plane between the two groups. There was no significant difference for intra-operative simple (P = 0.631) and total (simple+severe) (P = 0.649) septal mucoperichondrial injuries between groups 1 and 2, either. However, severe mucoperichondrial injury rate was higher in the patients infiltrated with lidocaine and adrenaline (P = 0.026), and the quality of the surgical field was worse in the patients injected with normal saline (P = 0.0179). Infiltration of septal mucoperichondrium with lidocaine and adrenaline instead of normal saline was not advantageous in terms of objective parameters tested, including bleeding amount and duration of surgery as well as the of the total mucosal injury rate in septoplasty procedure.

Full text: Objective: To determine whether the cerebral metabolism in various regions of the normal human brain differs from those of cancer patients in aging by using 18F-FDG PET instrument and SPM software. Materials and Methods We reviewed clinical information of 295 healthy normal samples so called 'normal group' (ranging 21 to 88; mean age+/-SD: 50+/-14) and 290 cancer patients called 'cancer group' (ranging 21 to 85; mean age+/-SD: 54+/-14) who were examined by a whole body GE Discovery LS PET-CT instrument in our center from Aug. 2004 to Dec. 2005.They were selected with: (i) absence of clear focal brain lesions (epilepsy, cerebrovascular diseases etc.); (ii) absence of metabolic diseases, such as hyperthyroidism, hypothyroidism and diabetes; (iii) absence of psychiatric disorders and abuse of drugs and alcohol;( iiii) cancer patients were diagnosed definitely of variable cancers except brain cancer or brain metastasis. Both groups were sub grouped into six with the interval of 10 years old starting from 21, and the gender, educational background and serum glucose are matched. All 12 subgroups were compared to the subgroup of normal 31-40 years old called 'control subgroup' (84 samples; mean age+/-SD: 37.15+/- 2.63). All samples were injected with 18F-FDG (5.55MBq/kg), 45-60 minutes later; their brains were scanned for 10 minutes. Pixel-by-pixel t-statistic analysis was applied to all brain images using the Statistical parametric mapping (SPM2). The hypometabolic areas (p < 0. 01 or p<0.001, uncorrected) were identified in the Stereotaxic coordinate human brain atlas and three dimensional localized by MNI Space utility (MSU) software. Results:1.With increasing of age interval, similar hypometabolic brain areas are detected in both 'normal group' and 'cancer group', they are mainly in the cortical structures such as bilateral prefrontal cortex (BA9), superior temporal gyrus (BA22), parietal cortex (inferior parietal lobule and precuneus(BA40), insula (BA13

Review of papers for methods of measuring sizes of ventricles and CSF space on CT revealed many different ways including subjective, linear, planimetric and volumetric methods. Results of these measurements were also reviewed and discussed together with our own study about normally acting elderly volunteers and patients with dimentia. The left lateral ventricle was significantly larger than the right. Sizes of ventricles and CSF spaces increased with aging. These differences were significant among five different age groups in female (younger than 60, sixties, seventies, eighties and older than 90). In male these differences were not significant among several age groups mainly because of a small number in an age group. There was no significant difference of sizes of ventricles and CSF space between male and female. The two variates analysis between sizes of ventricles and CSF space showed rightward shift of two main components in dementia compared with normal group. (author)

Intimate partner violence (IPV) during pregnancy may be common in settings where HIV is prevalent but there are few data on IPV in populations of HIV-infected pregnant women in Southern Africa. We examined the prevalence and correlates of IPV among HIV-infected pregnant women. A primary care antenatal clinic in Cape Town, South Africa. 623 consecutive HIV-infected pregnant women initiating lifelong antiretroviral therapy. IPV, depression, substance use and psychological distress were assessed using the 13-item WHO Violence Against Women questionnaire, the Edinburgh Postnatal Depression Scale (EPDS), Alcohol and Drug Use Disorders Identification Tests (AUDIT/DUDIT) and the Kessler 10 (K-10) scale, respectively. The median age in the sample was 28 years, 97% of women reported being in a relationship, and 70% of women reported not discussing and/or agreeing on pregnancy intentions before conception. 21% of women (n=132) reported experiencing ≥1 act of IPV in the past 12 months, including emotional (15%), physical (15%) and sexual violence (2%). Of those reporting any IPV (n=132), 48% reported experiencing 2 or more types. Emotional and physical violence was most prevalent among women aged 18-24 years, while sexual violence was most commonly reported among women aged 25-29 years. Reported IPV was less likely among married women, and women who experienced IPV were more likely to score above threshold for substance use, depression and psychological distress. In addition, women who reported not discussing and/or not agreeing on pregnancy intentions with their partner prior to conception were significantly more likely to experience violence. HIV-infected pregnant women in the study reported experiencing multiple forms of IPV. While the impact of IPV on maternal and child health outcomes in the context of HIV infection requires further research attention, IPV screening and support services should be considered within the package of routine care for HIV
