Outcome analysis of ulnar shortening osteotomy for ulnar impaction syndrome

Background Ulnar-sided wrist pain is a common problem in the upper extremity. It affects a broad patient population and can be difficult to treat. Ulnar impaction syndrome (UIS) is major cause of ulnar-sided wrist pain and a number of different operations have been used to correct it, including ulnar shortening osteotomy (USO). Objective To retrospectively review functional outcomes and complication rates of USO for UIS at the Hand and Upper Limb Centre (London, Ontario) over a two-year period. Methods Twenty-eight patients who underwent USO between 2007 and 2009 participated in the present study. Ulnar variance pre- and post-surgery was assessed using standard radiographic examination. Patient-rated outcomes were measured using a visual analogue scale (VAS) for pain and the Disabilities of the Arm, Shoulder and Hand (DASH) survey for functional outcomes. Objective grip strength and range of motion were compared with the contralateral extremity. Results On average, USO achieved a 3.11 mm reduction in ulnar variance. Nonunion occurred in five patients and required a secondary bone grafting procedure. All USO eventually healed. Overall, pain improved by 47.2% and the mean DASH score after surgery was 37.21. Flexion, extension and supination range of motion decreased by 10° compared with the unaffected side. Eleven patients (39%) elected to undergo a second surgery for hardware removal. Patients receiving compensation from the Workplace Safety and Insurance Board experienced significantly higher residual pain (VSA 5.24 versus 1.97) and disability levels (DASH 60.23 versus 25.70). Smokers also experienced worse outcomes in terms of pain (VSA 4.43 versus 2.36) and disability (DASH 51.06 versus 29.67). In this cohort, smoking was not associated with a higher rate of nonunion. Conclusion USO is effective in reducing pain in UIS and improves disability, at the price of a small decrease in range of motion. Smokers and people receiving compensation from the Workplace Safety and Insurance Board, however, have significantly worse subjective outcomes (VAS and DASH), but similar objective outcomes (range of motion).
Students' Exercise Frequency, Perceived Athletic Ability, Perceived Physical Attractiveness, Goal Orientations and Perceived Motivational Climate in Physical Education Classes

th year students (age 15 ± 0.5 years). All scales had acceptable levels of internal consistency and factor analyses supported further the psychometric properties of the questionnaires. One-way analysis of variance showed that students with an exercise frequency higher than 2 times per week scored higher in physical attractiveness and athletic ability scale while at the same time they had higher scores in task orientation and in task-involving climate. Hierarchical regression analysis revealed that task-involving climate, task orientation and self-perceptions contributed significantly to the percent of variance in exercise frequency. Ego orientation and ego- involving climate did not contribute to the model. These results suggest that the main objective of physical education teachers might be the shaping of a learning-oriented climate, where students won't worry about making mistakes, where there will be encouragement for everybody to believe that he/she can make it and everybody should be encouraged to adopt an orientation toward personal improvement.
EMOTIONAL INTELLIGENCE AND FAMILY ENVIRONMENT

The purpose of the study to examine the relationship between EQ and family environment. The sample of the study was selected as 274 parents who live in Istanbul including 152 female, 122 male. Data were collected by EQ-NED and “Family Environment Scale” to determine the EQ and family characteristics. The results of the study indicate that there was a relationship between EQ and family cooperation.
ADOLESCENTS' LIFE SATISFACTION: RISKY BEHAVIORS AND HOPELESSNESS

The aim of this study is to determine the contribution of risky behaviors and hopelessness in predicting adolescents' life satisfaction. Data of the study is obtained from a total of 290 students including 150 girls (51.7%) and 140 boys (48.3%) attending high school. In this study, Life Satisfaction Scale, Beck Hopelessness Scale and Risky behaviors Behaviour Scale are employed. As for data analysis, the Pearson Product-Moment Correlation Coefficient and the Hierarchical Regression Analysis are employed. According to analyses, it was determined that adolescents' hopelessness and risky behaviors predicted their life satisfactions positively. This result reveals that adolescent' risk behaviors and hopelessness decrease as their life satisfaction increases. In this sense, it is possible to contribute to decrease adolescents' risky behaviors and hopelessness by means of school-based prevention programs that focus on increasing adolescents' life satisfaction.
Diversity in Blue

Policing is an occupation that is gendered and sexualized. Ideals of heterosexual masculinity inform practices and social interactions within policing. This study explores how police officers manage a homosexual orientation within this organizational environment. Using qualitative survey responses from a sample of “out” and “closeted” gay and lesbian police officers in a Midwestern city, the authors examine (1) how heterosexual, masculine police organizations inform their experiences; (2) how officers construct multiple identities of sexual orientation, gender, and race-ethnicity; and (3) what strategies officers utilize to manage their homosexual orientation in the workplace. The authors are interested in how multiple identities involving race-ethnicity, gender, and “out” versus “closeted” status shape officers’ strategies for surviving in a potentially hostile work environment. The findings suggest that these officers support a more humane approach to policing and see themselves as particularly qualified to work within marginal communities. Despite the structural barriers of homophobia and sexism that tempered these officers’ full acceptance and access to the police subculture, lesbian and gay officers struggled to balance job demands with their sexual orientation, gender, race-ethnicity, and other dimensions of their identities.
The Effects of Teacher Social Presence on Student Satisfaction, Engagement, and Learning

This research experimentally manipulated the social presence cues in instructor's messages to students. The context was an online professional development one-credit course with one-to-one mentoring of students. Additionally, student learning intentions and levels of trust were examined as factors that may mitigate the effects of social presence. Results indicate that social presence affects the learner's interactions and perception of the instructor but has no effect on perceived learning, satisfaction, engagement, or the quality of their final course product. These findings suggest social presence is a correlational rather than a causal variable associated with student learning. Exploratory analyses suggest that trust and learning intentions are potentially important factors impacting student perceptions of the learning environment and performance in the course respectively.
Correlation between Patterns of Mdm2 SNIP 309 and Histopathological Severity of Helicobacter pylori Associated Gastritis in Thailand.

BACKGROUND The commonly held view of the tumor suppressor p53 is as a regulator of cell proliferation, apoptosis and many other biological processes as well as external and internal stress responses. Mdm2 SNIP309 is a negative regulator of p 53. Therefore, this study aimed to determine the correlation between the patterns of Mdm2 SNIP 309 and the inflammation grading of Helicobacter pylori associated gastritis in a Thai population. MATERIALS AND METHODS A cross-sectional study was carried out from November 2014 through June 2015. Biopsy specimens were obtained from infected patients and infection was proved by positive histology. The gastric mucosa specimens were sent to the Molecular Genetic Unit, Institute of Medicine, Suranaree University of Technology where they were tested by molecular methods to detect the patterns of Mdm2 SNIP 309 using the real-time PCR hybridization probe method. The results were analyzed and compared with the Updated Sydney classification. RESULTS A total of 100 infected patients were interviewed and gastric mucosa specimens were collected. In this study the percentage of Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygous was 78% and 19 % respectively whereas Mdm2 SNIP309 G/G homozygous was 3%. Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygous correlated with mild to moderate inflammation (P<0.01) whereas Mdm2 SNIP309 G/G homozygous correlated with severe inflammation (P<0.01). CONCLUSIONS Our study found the frequency of Mdm2 SNP309 G/G in our Thai population to be very low, and suggests that this can explain to some extent the low incidence of severe inflammation and gastric cancer changes in the Thai population. Mild to moderate inflammation are the most common pathologic gradings due to the unique genetic polymorphism of Mdm2 SNIP 309 in the Thai population.
A Key Role for Apoplastic H2O2 in Norway Spruce Phenolic Metabolism1[OPEN]

The redox state of the apoplast has a profound influence on cellular metabolism. Apoplastic events such as monolignol oxidation and lignin polymerization are difficult to study in intact trees. To investigate the role of apoplastic hydrogen peroxide (H2O2) in gymnosperm phenolic metabolism, an extracellular lignin-forming cell culture of Norway spruce (Picea abies) was used as a research model. Scavenging of apoplastic H2O2 by potassium iodide repressed lignin formation, in line with peroxidases activating monolignols for lignin polymerization. Time-course analyses coupled to candidate substrate-product pair network propagation revealed differential accumulation of low-molecular-weight phenolics, including (glycosylated) oligolignols, (glycosylated) flavonoids, and proanthocyanidins, in lignin-forming and H2O2-scavenging cultures and supported that monolignols are oxidatively coupled not only in the cell wall but also in the cytoplasm, where they are coupled to other monolignols and proanthocyanidins. Dilignol glycoconjugates with reduced structures were found in the culture medium, suggesting that cells are able to transport glycosylated dilignols to the apoplast. Transcriptomic analyses revealed that scavenging of apoplastic H2O2 resulted in remodulation of the transcriptome, with reduced carbon flux into the shikimate pathway propagating down to monolignol biosynthesis. Aggregated coexpression network analysis identified candidate enzymes and transcription factors for monolignol oxidation and apoplastic H2O2 production in addition to potential H2O2 receptors. The results presented indicate that the redox state of the apoplast has a profound influence on cellular metabolism.
African American Locational Attainment before the Civil Rights Era

The conventional wisdom is that due to intense discrimination, prior to the Civil Rights era blacks of all classes lived side by side. Individual socioeconomic status did not translate into improved locational outcomes according to this view. But several historical case studies suggest that upper–stratum blacks did indeed live in neighborhoods set apart from their poorer brethren. This study uses individual–level data from the 1910–1950 Public Use Microdata Samples to investigate how individual–level socioeconomic status translated into neighborhood–level outcomes for blacks. the study finds that among blacks, individual–level socioeconomic status played no role in determining residential proximity to whites. for blacks individual socioeconomic status was, however, an important determinant of other neighborhood outcomes.
Gender‐Typed Behaviors in Friendships and Well‐Being: A Cross‐Cultural Study of Chinese and American Boys

This 3-year, longitudinal analysis examined the psychological and social correlates of adhering to gender-typed behaviors in friendships among boys during middle school in United States (N = 446, Mage = 11.37 years) and in China (N = 368, Mage = 12.20 years). Results indicated that boys did not differ by nationality in the mean levels or in the increase over time in adherence to gender-typed behaviors. Furthermore, adherence over time was associated with higher depressive symptoms, lower self-esteem, and lower friendship quality for boys in both countries. However, the associations between gender-typed behaviors and friendship quality and depressive symptoms were stronger for boys in the United States. Our study suggests that gender-typed behaviors play an important role in the well-being of youth in different parts of the world.
Modeling Network Growth under Resource Constraints

We propose a resource-constrained network growth model that explains the emergence of key structural properties of real-world directed networks: heavy-tailed indegree distribution, high local clustering and degree-clustering relationship. In real-world networks, individuals form edges under constraints of limited network access and partial information. However, well-known growth models that preserve multiple structural properties do not incorporate these resource constraints. Conversely, existing resource-constrained models do not jointly preserve multiple structural properties of real-world networks. We propose a random walk growth model that explains how real-world network properties can jointly arise from edge formation under resource constraints. In our model, each node that joins the network selects a seed node from which it initiates a random walk. At each step of the walk, the new node either jumps back to the seed node or chooses an outgoing or incoming edge to visit another node. It links to each visited node with some probability and stops after forming a few edges. Our experimental results against four well-known growth models indicate improvement in accurately preserving structural properties of five citation networks. Our model also preserves two structural properties that most growth models cannot: skewed local clustering distribution and bivariate indegree-clustering relationship.
Surface Brightness Gradients Produced by the Ring Waves of Star Formation

We compute surface brightness profiles of galactic disks for outwardly propagating waves of star formation with a view to investigating the stellar populations in ring galaxies. We consider two mechanisms that can create outwardly propagating star-forming rings in a purely gaseous disk: a self-induced wave and a density wave. We show that the surface brightness profiles produced by both scenarios of ring formation are similar and are strongly sensitive to the velocity of the wave. The results of our computations are compared with the observational quantities sensitive to the young and old stellar populations in the ring galaxies A0035-335 (the Cartwheel Galaxy) and VII Zw 466. The best fit to the observed radial Hα surface brightness distribution in the Cartwheel Galaxy is obtained for a wave velocity of about 90 km s-1. The red continuum brightness of the ring can be fully explained by the evolving stars present in the trailing part of the wave. However, the red continuum brightness in regions internal to the ring indicates that the wave of star formation propagates in a preexisting stellar disk in the Cartwheel. The Hα and K-band surface brightness profiles in VII Zw 466 match very well the values expected from stellar populations produced by a wave of star formation propagating in a purely gaseous disk. We conclude that VII Zw 466 is probably experiencing the first event of star formation in the disk.
Novice and expert haptic behaviours while using a robot controlled surgery system

STRAS (Single access Transluminal Robotic Assistant for Surgeons) is a flexible robotic system based on the Anubis® platform of Karl Storz for application to intraluminal procedures. It consists of three cable-driven systems, one endoscope serving as guide and two inserted instruments. The flexible and bendable instruments have three degrees of freedom and can be teleoperated by a single user via two specially designed master interfaces. In this research, a pair of specific sensor gloves, which ergonomically fit to the master handles of the system was designed and the forces applied by one expert and one novice user during system-specific task execution were compared. The results show that user expertise is not only reflected by shorter task execution times, but also by specific differences in handgrip forces applied during the manipulations.
Molecular characterization of immortalized normal and dysplastic oral cell lines.

BACKGROUND Cell lines have been developed for modeling cancer and cancer progression. The molecular background of these cell lines is often unknown to those using them to model disease behaviors. As molecular alterations are the ultimate drivers of cell phenotypes, having an understanding of the molecular make-up of these systems is critical for understanding the disease biology modeled. METHODS Six immortalized normal, one immortalized dysplasia, one self-immortalized dysplasia, and two primary normal cell lines derived from oral tissues were analyzed for DNA copy number changes and changes in both mRNA and miRNA expression using SMRT-v.2 genome-wide tiling comparative genomic hybridization arrays, Agilent Whole Genome 4x44k expression arrays, and Exiqon V2.M-RT-PCR microRNA Human panels. RESULTS DNA copy number alterations were detected in both normal and dysplastic immortalized cell lines-as well as in the single non-immortalized dysplastic cell line. These lines were found to have changes in expression of genes related to cell cycle control as well as alterations in miRNAs that are deregulated in clinical oral squamous cell carcinoma tissues. Immortal lines-whether normal or dysplastic-had increased disruption in expression relative to primary lines. All data are available as a public resource. CONCLUSIONS Molecular profiling experiments have identified DNA, mRNA, and miRNA alterations for a panel of normal and dysplastic oral tissue cell lines. These data are a valuable resource to those modeling diseases of the oral mucosa, and give insight into the selection of model cell lines and the interpretation of data from those lines.
Reach and Visibility: Perception and Social Marketing of AIDS Patients in Malaysian Media

Media has the potential in shaping and reshaping people’s opinion, behaviour, and notion on an issue or event. In addition to reach the public cohesive, the media representation on HIV/AIDS-related issues are essential inevitability. Coverage-related HIV issues can be potent means of perceiving people behaviour. However, even though the news on AIDS and HIV epidemic has attracted public attention, gain followers, taken as a vital social health problem, and gaining prominence in the national agenda, the social marketing programmes on AIDS patients in Malaysia is still lacking momentum. Thus, this paper examined the perception, visibility and reach of the social marketing programmes of AIDS patients in the Malaysian media. The methodology chosen allows examination of media attitude, coverage and exposure of correct information on HIV and AIDS and audience or community reaction towards People Living with HIV (PLHIV) by analyzing social marketing programmes in Malaysia media. Agenda setting theory is used as theoretical framework to examine the news coverage on issue of AIDS and public opinion built through the Malaysian social marketing programmes. Three selected Malaysian Newspapers (Utusan Malaysia, The Star, and Sin Chew Jit Po) were content analysed. A less favourable in the social agenda setting by the media were portrayed when it comes to HIV-related and social marketing issues. The portrayal of HIV-related issues hardly secured the national pages even for the month that carries the highest amount on HIV-related issues news. Most of the social marketing programmes were awareness messages to the public about HIV-related issues in order to achieve behaviour changes against HIV/AIDS-related negative perceptions. Social marketing program received little attention in the local media, hence implicating of a lesser media agenda towards promoting an idea or a program to gain behaviour change among the public about HIV-related problems.
Self-contained indoor positioning on off-the-shelf mobile devices

We introduce a novel self-contained seamless positioning solution for indoor and outdoor environments, well suited for and designed to be operated on off-the-shelf mobile phones. Position information is deduced from a combination of GNSS where available, combined with Pedestrian Dead Reckoning (PDR) utilizing inertial measurements and context-aware activity based map matching. The proposed system heavily exploits different types of human movement, such as walking, running, ascending or descending stairs, to improve the employed positioning model. In remaining independent from any external infrastructure, accurate localization is also possible in environments, where the installation and maintenance of such infrastructure does not make sense or is simply not affordable - as for example in a parking garage to guide a user to the next exit or back to his car. Concerning this particular use case we have also implemented an interface for the synchronization of location information between the mobile positioning solution and the car.
The Impact of Contemporary Contact Lenses on Contact Lens Discontinuation

Objectives: Discontinuation or “dropout” from contact lens (CL) wear continues to afflict the CL industry. This study was conducted to determine whether the advent of new CL materials and designs has impacted the dropout rate and the reasons for discontinuation. Methods: Current and lapsed CL wearers residing in Canada were recruited using Facebook to take part in an on line survey investigating CL wearing experiences during 2008 to 2010 and to establish the percentage of participants who temporarily and permanently discontinued CL wear during the period surveyed. Results: Four thousand two hundred seven eligible surveys were received (64% female; median age 27 years). Forty percent had lapsed from lens wear for at least 4 months; however, 62% of the lapsed wearers (LWs) resumed wear. There were no differences between LWs and nonlapsed wearers (NLWs) with respect to gender; however, LWs were older, started lens wear when older, and had not worn lenses for as long as NLWs (all P<0.001). More NLWs than LWs wore silicone hydrogel CLs (49% vs. 38%, P<0.001) and more LWs than NLWs wore daily disposable lenses and hydrogel CLs (24% vs. 19% and 22% vs. 18%, respectively, P⩽0.001). Primary reasons for discontinuation were discomfort (24%), dryness (20%), red eyes (7%), and expense (7%). Compliance with lens replacement was no different between LWs and NLWs (48% vs. 45%). Conclusions: About 23% of those surveyed had discontinued CL wear permanently. The primary reasons for dropping out continue to be discomfort and dryness. Dropout rates were lower in silicone hydrogel wearers.
