Duricki, Denise A; Soleman, Sara; Moon, Lawrence D F

2016-06-01

Testing of therapies for disease or injury often involves the analysis of longitudinal data from animals. Modern analytical methods have advantages over conventional methods (particularly when some data are missing), yet they are not used widely by preclinical researchers. Here we provide an easy-to-use protocol for the analysis of longitudinal data from animals, and we present a click-by-click guide for performing suitable analyses using the statistical package IBM SPSS Statistics software (SPSS). We guide readers through the analysis of a real-life data set obtained when testing a therapy for brain injury (stroke) in elderly rats. If a few data points are missing, as in this example data set (for example, because of animal dropout), repeated-measures analysis of covariance may fail to detect a treatment effect. An alternative analysis method, such as the use of linear models (with various covariance structures), and analysis using restricted maximum likelihood estimation (to include all available data) can be used to better detect treatment effects. This protocol takes 2 h to carry out.

SPSS and SAS programs for comparing Pearson correlations and OLS regression coefficients.

PubMed

Weaver, Bruce; Wuensch, Karl L

2013-09-01

Several procedures that use summary data to test hypotheses about Pearson correlations and ordinary least squares regression coefficients have been described in various books and articles. To our knowledge, however, no single resource describes all of the most common tests. Furthermore, many of these tests have not yet been implemented in popular statistical software packages such as SPSS and SAS. In this article, we describe all of the most common tests and provide SPSS and SAS programs to perform them. When they are applicable, our code also computes 100 × (1 - α)% confidence intervals corresponding to the tests. For testing hypotheses about independent regression coefficients, we demonstrate one method that uses summary data and another that uses raw data (i.e., Potthoff analysis). When the raw data are available, the latter method is preferred, because use of summary data entails some loss of precision due to rounding.

SPSS and SAS programs for generalizability theory analyses.

2006-08-01

The identification and reduction of measurement errors is a major challenge in psychological testing. Most investigators rely solely on classical test theory for assessing reliability, whereas most experts have long recommended using generalizability theory instead. One reason for the common neglect of generalizability theory is the absence of analytic facilities for this purpose in popular statistical software packages. This article provides a brief introduction to generalizability theory, describes easy to use SPSS, SAS, and MATLAB programs for conducting the recommended analyses, and provides an illustrative example, using data (N = 329) for the Rosenberg Self-Esteem Scale. Program output includes variance components, relative and absolute errors and generalizability coefficients, coefficients for D studies, and graphs of D study results.

SPSS macros to compare any two fitted values from a regression model.

PubMed

Weaver, Bruce; Dubois, Sacha

2012-12-01

In regression models with first-order terms only, the coefficient for a given variable is typically interpreted as the change in the fitted value of Y for a one-unit increase in that variable, with all other variables held constant. Therefore, each regression coefficient represents the difference between two fitted values of Y. But the coefficients represent only a fraction of the possible fitted value comparisons that might be of interest to researchers. For many fitted value comparisons that are not captured by any of the regression coefficients, common statistical software packages do not provide the standard errors needed to compute confidence intervals or carry out statistical tests-particularly in more complex models that include interactions, polynomial terms, or regression splines. We describe two SPSS macros that implement a matrix algebra method for comparing any two fitted values from a regression model. The !OLScomp and !MLEcomp macros are for use with models fitted via ordinary least squares and maximum likelihood estimation, respectively. The output from the macros includes the standard error of the difference between the two fitted values, a 95% confidence interval for the difference, and a corresponding statistical test with its p-value.

In this research, probable arsenic contamination in drinking water in the city of Ardabil was studied in 163 samples during four seasons. In each season, sampling was carried out randomly in the study area. Results were analyzed statistically applying SPSS 19 software, and the data was also modeled by Arc GIS 10.1 software. The maximum permissible arsenic concentration in drinking water defined by the World Health Organization and Iranian national standard is 10 μg/L. Statistical analysis showed 75, 88, 47, and 69% of samples in autumn, winter, spring, and summer, respectively, had concentrations higher than the national standard. The mean concentrations of arsenic in autumn, winter, spring, and summer were 19.89, 15.9, 10.87, and 14.6 μg/L, respectively, and the overall average in all samples through the year was 15.32 μg/L. Although GIS outputs indicated that the concentration distribution profiles changed in four consecutive seasons, variance analysis of the results showed that statistically there is no significant difference in arsenic levels in four seasons.

This study examined the types and extent of competitive foods available in public high schools in Pennsylvania. We developed, pilot tested, and distributed surveys to school foodservice directors in a random sample of 271 high schools in Pennsylvania. Two hundred twenty-eight surveys were returned, for a response rate of 84%. Statistical analyses were performed: Descriptive statistics were used to examine the extent of competitive food sales in Pennsylvania public high schools. The survey data were analyzed using SPSS software version 11.5.1 (2002, SPSS base 11.0 for Windows, SPSS Inc, Chicago, IL). A la carte sales provide almost dollar 700/day to school foodservice programs, almost 85% of which receive no financial support from their school districts. The top-selling a la carte items are "hamburgers, pizza, and sandwiches." Ninety-four percent of respondents indicated that vending machines are accessible to students. The item most commonly offered in vending machines is bottled water (71.5%). While food items are less often available through school stores and club fund-raisers, candy is the item most commonly offered through these sources. Competitive foods are widely available in high schools. Although many of the items available are low in nutritional value, we found several of the top-selling a la carte options to be nutritious and bottled water the item most often identified as available through vending machines.

IBM Watson Analytics: Automating Visualization, Descriptive, and Predictive Statistics

PubMed Central

2016-01-01

Background We live in an era of explosive data generation that will continue to grow and involve all industries. One of the results of this explosion is the need for newer and more efficient data analytics procedures. Traditionally, data analytics required a substantial background in statistics and computer science. In 2015, International Business Machines Corporation (IBM) released the IBM Watson Analytics (IBMWA) software that delivered advanced statistical procedures based on the Statistical Package for the Social Sciences (SPSS). The latest entry of Watson Analytics into the field of analytical software products provides users with enhanced functions that are not available in many existing programs. For example, Watson Analytics automatically analyzes datasets, examines data quality, and determines the optimal statistical approach. Users can request exploratory, predictive, and visual analytics. Using natural language processing (NLP), users are able to submit additional questions for analyses in a quick response format. This analytical package is available free to academic institutions (faculty and students) that plan to use the tools for noncommercial purposes. Objective To report the features of IBMWA and discuss how this software subjectively and objectively compares to other data mining programs. Methods The salient features of the IBMWA program were examined and compared with other common analytical platforms, using validated health datasets. Results Using a validated dataset, IBMWA delivered similar predictions compared with several commercial and open source data mining software applications. The visual analytics generated by IBMWA were similar to results from programs such as Microsoft Excel and Tableau Software. In addition, assistance with data preprocessing and data exploration was an inherent component of the IBMWA application. Sensitivity and specificity were not included in the IBMWA predictive analytics results, nor were odds ratios, confidence intervals, or a confusion matrix. Conclusions IBMWA is a new alternative for data analytics software that automates descriptive, predictive, and visual analytics. This program is very user-friendly but requires data preprocessing, statistical conceptual understanding, and domain expertise. PMID:27729304

This review article presents an assessment of trends in statistical methods and an evaluation of their appropriateness in articles published in the Archives of Plastic Surgery (APS) from 2012 to 2017. We reviewed 388 original articles published in APS between 2012 and 2017. We categorized the articles that used statistical methods according to the type of statistical method, the number of statistical methods, and the type of statistical software used. We checked whether there were errors in the description of statistical methods and results. A total of 230 articles (59.3%) published in APS between 2012 and 2017 used one or more statistical method. Within these articles, there were 261 applications of statistical methods with continuous or ordinal outcomes, and 139 applications of statistical methods with categorical outcome. The Pearson chi-square test (17.4%) and the Mann-Whitney U test (14.4%) were the most frequently used methods. Errors in describing statistical methods and results were found in 133 of the 230 articles (57.8%). Inadequate description of P-values was the most common error (39.1%). Among the 230 articles that used statistical methods, 71.7% provided details about the statistical software programs used for the analyses. SPSS was predominantly used in the articles that presented statistical analyses. We found that the use of statistical methods in APS has increased over the last 6 years. It seems that researchers have been paying more attention to the proper use of statistics in recent years. It is expected that these positive trends will continue in APS.

The need for hands-on computer laboratory experience in undergraduate and graduate statistics education has been firmly established in the past decade. As a result a number of attempts have been undertaken to develop novel approaches for problem-driven statistical thinking, data analysis and result interpretation. In this paper we describe an integrated educational web-based framework for: interactive distribution modeling, virtual online probability experimentation, statistical data analysis, visualization and integration. Following years of experience in statistical teaching at all college levels using established licensed statistical software packages, like STATA, S-PLUS, R, SPSS, SAS, Systat, etc., we have attempted to engineer a new statistics education environment, the Statistics Online Computational Resource (SOCR). This resource performs many of the standard types of statistical analysis, much like other classical tools. In addition, it is designed in a plug-in object-oriented architecture and is completely platform independent, web-based, interactive, extensible and secure. Over the past 4 years we have tested, fine-tuned and reanalyzed the SOCR framework in many of our undergraduate and graduate probability and statistics courses and have evidence that SOCR resources build student’s intuition and enhance their learning.

Background Although a substantial number of studies focus on the teaching and application of medical statistics in China, few studies comprehensively evaluate the recognition of and demand for medical statistics. In addition, the results of these various studies differ and are insufficiently comprehensive and systematic. Objectives This investigation aimed to evaluate the general cognition of and demand for medical statistics by undergraduates, graduates, and medical staff in China. Methods We performed a comprehensive database search related to the cognition of and demand for medical statistics from January 2007 to July 2014 and conducted a meta-analysis of non-controlled studies with sub-group analysis for undergraduates, graduates, and medical staff. Results There are substantial differences with respect to the cognition of theory in medical statistics among undergraduates (73.5%), graduates (60.7%), and medical staff (39.6%). The demand for theory in medical statistics is high among graduates (94.6%), undergraduates (86.1%), and medical staff (88.3%). Regarding specific statistical methods, the cognition of basic statistical methods is higher than of advanced statistical methods. The demand for certain advanced statistical methods, including (but not limited to) multiple analysis of variance (ANOVA), multiple linear regression, and logistic regression, is higher than that for basic statistical methods. The use rates of the Statistical Package for the Social Sciences (SPSS) software and statistical analysis software (SAS) are only 55% and 15%, respectively. Conclusion The overall statistical competence of undergraduates, graduates, and medical staff is insufficient, and their ability to practically apply their statistical knowledge is limited, which constitutes an unsatisfactory state of affairs for medical statistics education. Because the demand for skills in this area is increasing, the need to reform medical statistics education in China has become urgent. PMID:26053876

2015-01-01

To compare the results of Pearson residual calculations in logistic regression models using SPSS and SAS. We reviewed Pearson residual calculation methods, and used two sets of data to test logistic models constructed by SPSS and STATA. One model contained a small number of covariates compared to the number of observed. The other contained a similar number of covariates as the number of observed. The two software packages produced similar Pearson residual estimates when the models contained a similar number of covariates as the number of observed, but the results differed when the number of observed was much greater than the number of covariates. The two software packages produce different results of Pearson residuals, especially when the models contain a small number of covariates. Further studies are warranted.

It is urgently necessary to be aware of the distribution and employment status of college graduates for proper allocation of human resources and overall arrangement of strategic industry. This study provides empirical evidence regarding the use of geocoding and spatial analysis in distribution and employment status of college graduates based on the data from 2004-2008 Wuhan Municipal Human Resources and Social Security Bureau, China. Spatio-temporal distribution of employment unit were analyzed with geocoding using ArcGIS software, and the stepwise multiple linear regression method via SPSS software was used to predict the employment and to identify spatially associated enterprise and professionals demand in the future. The results show that the enterprises in Wuhan east lake high and new technology development zone increased dramatically from 2004 to 2008, and tended to distributed southeastward. Furthermore, the models built by statistical analysis suggest that the specialty of graduates major in has an important impact on the number of the employment and the number of graduates engaging in pillar industries. In conclusion, the combination of GIS and statistical analysis which helps to simulate the spatial distribution of the employment status is a potential tool for human resource development research.

To evaluate the necessity of ocular screening in Type 1 diabetes mellitus (DM). This study aims to investigate the diabetes-related ocular changes according to the glycosylated hemoglobin (HbA1c) level and duration of diabetes in children and compare the results with nondiabetic healthy children. Observational cross-sectional study designed by ophthalmology and pediatric endocrinology clinics. Forty-two children with Type 1 DM, 42 healthy gender- and age-matched children as controls were enrolled. All patients underwent ophthalmic and physical examination, with a review of medical history and current medication. HbA1c level, best corrected visual acuity, intraocular pressure (IOP), central corneal thickness (CCT), tear break-up time (BUT), Schirmer test, dilated fundus examination findings, central retinal thickness (CRT), and total macular volume (TMV) measurements were noted. Descriptive statistics, Student's t-test, Mann-Whitney U-test, Chi-square test for comparison of the group parameters and correlation analyses (Spearman analysis) were performed with SPSS statistical software 17.0 (SPSS Inc., Chicago, IL, USA). Type 1 DM group exhibited significantly reduced Schirmer test, increased IOP and decreased retinal thickness relative to the age-matched control group (P < 0.05) but no statistically significant difference was found for the BUT (P = 0.182) and for the CCT (P = 0.495). The correlations between the age, duration, HbA1c and IOP, BUT, Schirmer test, TMV, CRT measurements did not reach statistical significance. More frequent screening may be needed for complications, including neuropathy-related dry eye syndrome, IOP changes, and diabetic retinopathy in children with Type 1 DM.

Sustained vowel is a widely used material of acoustic analysis. However, vowel phonation does not sufficiently demonstrate sentence-based real-life phonation, and biases may occur depending on the test subjects intent during pronunciation. The purpose of this study was to investigate the differences between the results of acoustic analysis using each material. An individual prospective study. Two hundred two individuals (87 men and 115 women) with normal findings in videostroboscopy were enrolled. Acoustic analysis was done using the speech pattern element acquisition and display program. Fundamental frequency (Fx), amplitude (Ax), contact quotient (Qx), jitter, and shimmer were measured with sustained vowel-based acoustic analysis. Average fundamental frequency (FxM), average amplitude (AxM), average contact quotient (QxM), Fx perturbation (CFx), and amplitude perturbation (CAx) were measured with sentence-based acoustic analysis. Corresponding data of the two methods were compared with each other. SPSS (Statistical Package for the Social Sciences, Version 12.0; SPSS, Inc., Chicago, IL) software was used for statistical analysis. FxM was higher than Fx in men (Fx, 124.45 Hz; FxM, 133.09 Hz; P=0.000). In women, FxM seemed to be lower than Fx, but the results were not statistically significant (Fx, 210.58 Hz; FxM, 208.34 Hz; P=0.065). There was no statistical significance between Ax and AxM in both the groups. QxM was higher than Qx in men and women. Jitter was lower in men, but CFx was lower in women. Both Shimmer and CAx were higher in men. Sustained vowel phonation could not be a complete substitute for real-time phonation in acoustic analysis. Characteristics of acoustic materials should be considered when choosing the material for acoustic analysis and interpreting the results. Copyright © 2012 The Voice Foundation.

Hypertension is one of the important contributing factors linked with both causation and development of kidney disease. It is a multifactorial, polygenic, and complex disorder due to interaction of several risk genes with environmental factors. The present study was aimed to explore genetic polymorphism in ACE-1 gene as a risk factor for CKD among hypertensive patients. Three hundred patients were enrolled in the study. Ninety were hypertensive patients with CKD taken as cases, whereas 210 hypertensive patients without CKD were taken as controls. Demographic data including age, sex, Body mass index (BMI), and other risk factors were also recorded. DNA was extracted from blood by salting out method. Genotyping of ACE gene was done by PCR technique. All the statistical analysis was done by using Epi Info and SPSS version 16 software (SPSS Inc., Chicago, IL). Mean age was higher in the control group (p < 0.05). Variables among two groups were compared out of which age, BMI, hemoglobin (Hb) was found to be statistically significant whereas other variables like systolic blood pressure, triglyceride and low-density lipoprotein were not. Blood urea and serum creatinine levels were statistically significant in the two genotypes (p < 0.05). Total and HDL cholesterol were statistically significant for DD genotype of ACE gene (OR = 1.42, 95% CI = 0.72-2.81). Similarly, the risk for CKD among hypertensive patients was also associated with D allele of ACE gene (OR = 1.25, 95% CI = 0.86-1.79). It is concluded that ACE-DD genotype may be a risk factor for the causation and development of chronic kidney failure among hypertensive patients.

The development and integration of a personal digital assistant (PDA)-based point-of-care database into an intravenous resource nurse (IVRN) consultation service for the purposes of consultation management and service characterization are described. The IVRN team provides a consultation service 7 days a week in this 1000-bed tertiary adult care teaching hospital. No simple, reliable method for documenting IVRN patient care activity and facilitating IVRN-initiated patient follow-up evaluation was available. Implementation of a PDA database with exportability of data to statistical analysis software was undertaken in July 2001. A Palm IIIXE PDA was purchased and a three-table, 13-field database was developed using HanDBase software. During the 7-month period of data collection, the IVRN team recorded 4868 consultations for 40 patient care areas. Full analysis of service characteristics was conducted using SPSS 10.0 software. Team members adopted the new technology with few problems, and the authors now can efficiently track and analyze the services provided by their IVRN team.

The Statistical Package for the Social Sciences (SPSS) as an adjunct to pharmacokinetic analysis.

Computer techniques for numerical analysis are well known to pharmacokineticists. Powerful techniques for data file management have been developed by social scientists but have, in general, been ignored by pharmacokineticists because of their apparent lack of ability to interface with pharmacokinetic programs. Extensive use has been made of the Statistical Package for the Social Sciences (SPSS) for its data handling capabilities, but at the same time, techniques have been developed within SPSS to interface with pharmacokinetic programs of the users' choice and to carry out a variety of user-defined pharmacokinetic tasks within SPSS commands, apart from the expected variety of statistical tasks. Because it is based on a ubiquitous package, this methodology has all of the benefits of excellent documentation, interchangeability between different types and sizes of machines and true portability of techniques and data files. An example is given of the total management of a pharmacokinetic study previously reported in the literature by the authors.

The purpose of this study was to evaluate the relationship between sitting volleyball performance and the field fitness of sitting volleyball players. Forty-five elite sitting volleyball players participated in 10 field fitness tests. Additionally, the players’ head coach and coach assessed their volleyball performance (receive and defense, block, attack, and serve). Data were analyzed with SPSS software version 21 by using correlation and regression analyses, and the significance level was set at P< 0.05. The results showed that chest pass, overhand throw, one-hand throw, one-hand side throw, splint, speed endurance, reaction time, and graded exercise test results had a statistically significant influence on the players’ abilities to attack, serve, and block. Grip strength, t-test, speed, and agility showed a statistically significant relationship with the players’ skill at defense and receive. Our results showed that chest pass, overhand throw, one-hand throw, one-hand side throw, speed endurance, reaction time, and graded exercise test results had a statistically significant influence on volleyball performance.

Janssen, Dirk P

2012-03-01

Psychologists, psycholinguists, and other researchers using language stimuli have been struggling for more than 30 years with the problem of how to analyze experimental data that contain two crossed random effects (items and participants). The classical analysis of variance does not apply; alternatives have been proposed but have failed to catch on, and a statistically unsatisfactory procedure of using two approximations (known as F(1) and F(2)) has become the standard. A simple and elegant solution using mixed model analysis has been available for 15 years, and recent improvements in statistical software have made mixed models analysis widely available. The aim of this article is to increase the use of mixed models by giving a concise practical introduction and by giving clear directions for undertaking the analysis in the most popular statistical packages. The article also introduces the DJMIXED: add-on package for SPSS, which makes entering the models and reporting their results as straightforward as possible.

The aim of this study is filling the gap in the literature about investigating the effect of yarn and fabric structural parameters on burning behavior of polyester fabrics. According to the experimental design three different fabric types, three different weft densities and two different weave types were selected and a total of eighteen different polyester drapery fabrics were produced. All statistical procedures were conducted using the SPSS Statistical software package. The results of the Analysis of Variance (ANOVA) tests indicated that; there were statistically significant (5% significance level) differences between the mass loss ratios (%) in weft and mass loss ratios (%) in warp direction of different fabrics calculated after the flammability test. The Student-Newman-Keuls (SNK) results for mass loss ratios (%) both in weft and warp directions revealed that the mass loss ratios (%) of fabrics containing Trevira CS type polyester were lower than the mass loss ratios of polyester fabrics subjected to washing treatment and flame retardancy treatment.

Background: Age estimation of living or deceased individuals is an important aspect of forensic sciences. Conventionally, pulp-to-tooth area ratio (PTR) measured from periapical radiographs have been utilized as a nondestructive method of age estimation. Cone-beam computed tomography (CBCT) is a new method to acquire three-dimensional images of the teeth in living individuals. Aims: The present study investigated age estimation based on PTR of the maxillary canines measured in three planes obtained from CBCT image data. Settings and Design: Sixty subjects aged 20–85 years were included in the study. Materials and Methods: For each tooth, mid-sagittal, mid-coronal, and three axial sections—cementoenamel junction (CEJ), one-fourth root level from CEJ, and mid-root—were assessed. PTR was calculated using AutoCAD software after outlining the pulp and tooth. Statistical Analysis Used: All statistical analyses were performed using an SPSS 17.0 software program. Results and Conclusions: Linear regression analysis showed that only PTR in axial plane at CEJ had significant age correlation (r = 0.32; P < 0.05). This is probably because of clearer demarcation of pulp and tooth outline at this level. PMID:28123269

To determine the surgically induced astigmatism (SIA) in Straight, Frown and Inverted V shape (Chevron) incisions in manual small incision cataract surgery (SICS). A prospective cross sectional study was done on a total of 75 patients aged 40y and above with senile cataract. The patients were randomly divided into three groups (25 each). Each group received a particular type of incision (Straight, Frown or Inverted V shape incisions). Manual SICS with intraocular lens (IOL) implantation was performed. The patients were compared 4wk post operatively for uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) and SIA. All calculations were performed using the SIA calculator version 2.1, a free software program. The study was analyzed using SPSS version 15.0 statistical analysis software. The study found that 89.5% of patients in Straight incision group, 94.2% in Frown incision group and 95.7% in Inverted V group attained BCVA post-operatively in the range of 6/6 to 6/18. Mean SIA was minimum (-0.88±0.61D×90 degrees) with Inverted V incision which was statistically significant. Inverted V (Chevron) incision gives minimal SIA.

College students are one of the most at-risk population groups for food poisoning, due to risky food safety behaviors. Using the Likert Scale, undergraduate students were asked to participate in a Food Safety Survey which was completed by 499 students ages 18-25. Data was analyzed using SPSS and AMOS statistical software. Four conceptual definitions regarding food safety were defined as: general food safety, bacterial food safety, produce food safety, and politics associated with food safety. Knowledge seems to be an important factor in shaping students attitudes regarding general and bacterial safety. Ethnicity plays a role in how people view the politics of food safety, and the safety of organic foods.

Career management skills are important elements that should be present in each individual, because career selection process is crucial for school leavers. The phenomenon of students who are less knowledgeable about career at the end of school is among the main reasons they choose a career that does not fit. The situation is very worrying and poses various negative implications such as work stress and frequent swapping of jobs. In fact, research has found that most vocational students have a low level of career management. Therefore, this study is aimed to identify career management skills that students possess. The research design was a survey using a quantitative approach with a number of samples, n = 480. Data was analysed using statistical software, Statistical Package for the Social Sciences (SPSS). The results show that students’ overall career management skills are moderate. To develop human capital with the right competence, career management skills are critical requirements that can fill the gaps in industry.

Statistics is an integral part of Clinical Trials. Elements of statistics span Clinical Trial design, data monitoring, analyses and reporting. A solid understanding of statistical concepts by clinicians improves the comprehension and the resulting quality of Clinical Trials. In biomedical research it has been seen that researcher frequently use t-test and ANOVA to compare means between the groups of interest irrespective of the nature of the data. In Clinical Trials we record the data on the patients more than two times. In such a situation using the standard ANOVA procedures is not appropriate as it does not consider dependencies between observations within subjects in the analysis. To deal with such types of study data Repeated Measure ANOVA should be used. In this article the application of One-way Repeated Measure ANOVA has been demonstrated by using the software SPSS (Statistical Package for Social Sciences) Version 15.0 on the data collected at four time points 0 day, 15th day, 30th day, and 45th day of multicentre clinical trial conducted on Pandu Roga (~Iron Deficiency Anemia) with an Ayurvedic formulation Dhatrilauha.

Majority of the developmental delays in children are non-syndromic and they are believed to have an underlying DNA damage, though not well substantiated. Hence the present study was carried out to find out if there is any increased DNA damage in children with non-syndromic developmental delay by using the comet assay. The present case-control study was undertaken to assess the level of DNA damage in children with non syndromic developmental delay and compare the same with that of age and sex matched controls using submarine gel electrophoresis (Comet Assay). The blood from clinically diagnosed children with non syndromic developmental delay and controls were subjected for alkaline version of comet assay - Single cell gel electrophoresis using lymphocytes isolated from the peripheral blood. The comets were observed under a bright field microscope; photocaptured and scored using the Image J image quantification software. Comet parameters were compared between the cases and controls and statistical analysis and interpretation of results was done using the statistical software SPSS version 20. The mean comet tail length in cases and control was 20.77+7.659μm and 08.97+4.398μm respectively which was statistically significant (p<0.001). Other comet parameters like total comet length and % DNA in tail also showed a statistically significant difference (p < 0.001) between cases and controls. The current investigation unraveled increased levels of DNA damage in children with non syndromic developmental delay when compared to the controls.

The aim of this study is to assess the caries risk assessment of 12-13-year-old government and private school going children of Mysore city using Cariogram. A cross-sectional examination was carried out on a total of 104 government and private schoolchildren aged 12-13 years. Ten factors from the Cariogram software(D Bratthall, Computer software, Malmo, Sweden) were included from study participant's records to complete the Cariogram. The percentage of "chances of avoiding new lesions" (caries risk) among government and private school study participants were obtained from Cariogram, and the participants were classified into five risk groups. Statistical analysis was performed using the software program Statistical Package of Social Science (version 17.0, SPSS Inc., Chicago IL, USA). Findings revealed that there is slight difference in caries risk among government and private schoolchildren, where 48% caries risk development and 52% chance to avoid dental caries were showed in government schoolchildren, and 51% caries risk development and 49% chance to avoid dental caries were showed in private schoolchildren, according to Cariogram. Decayed, missing, and filled teeth component, mutans streptococci, and Lactobacillus counts were slightly higher in private schoolchildren compared with government schoolchildren. The private schoolchildren had less favorable values than government schoolchildren for most of the caries-related factors. Cariogram can be the most modest and reliable tool for caries prediction, thus aiding in identifying different risk groups in a community so that appropriate preventive strategies can be provided to overcome new carious lesion formation.

To develop an in-house software program that is able to calculate and generate the biological dose distribution and biological dose volume histogram by physical dose conversion using the linear-quadratic-linear (LQL) model. The Isobio software was developed using MATLAB version 2014b to calculate and generate the biological dose distribution and biological dose volume histograms. The physical dose from each voxel in treatment planning was extracted through Computational Environment for Radiotherapy Research (CERR), and the accuracy was verified by the differentiation between the dose volume histogram from CERR and the treatment planning system. An equivalent dose in 2 Gy fraction (EQD 2 ) was calculated using biological effective dose (BED) based on the LQL model. The software calculation and the manual calculation were compared for EQD 2 verification with pair t -test statistical analysis using IBM SPSS Statistics version 22 (64-bit). Two and three-dimensional biological dose distribution and biological dose volume histogram were displayed correctly by the Isobio software. Different physical doses were found between CERR and treatment planning system (TPS) in Oncentra, with 3.33% in high-risk clinical target volume (HR-CTV) determined by D 90% , 0.56% in the bladder, 1.74% in the rectum when determined by D 2cc , and less than 1% in Pinnacle. The difference in the EQD 2 between the software calculation and the manual calculation was not significantly different with 0.00% at p -values 0.820, 0.095, and 0.593 for external beam radiation therapy (EBRT) and 0.240, 0.320, and 0.849 for brachytherapy (BT) in HR-CTV, bladder, and rectum, respectively. The Isobio software is a feasible tool to generate the biological dose distribution and biological dose volume histogram for treatment plan evaluation in both EBRT and BT.

To evaluate physicians' current practice, attitudes toward, and knowledge of cancer pain management in China. We conducted a face-to-face survey of physicians (oncologists, internists, hematologists) who are responsible for the care of cancer patient of 11 general hospitals in Sichuan, China between December 2011 and December 2013. Statistical analyses were performed using SPSS (SPSS, Chicago, IL) software. A 23-item questionnaire was designed and distributed to 550 physicians in 11 medical facilities in China. Five hundred (90.90%) physicians responded. About one-third (32.6%) of physicians assessed patients' pain rarely, and 85.5% never or occasionally treated patients' cancer pain together with psychologists. More than half of physicians indicated that opioid dose titration in patients with poor pain control and assessment of the cause and severity of pain were urgently needed knowledge for cancer pain management. Inadequate assessment of pain and pain management (63.0%), patients' reluctance to take opioids (62.2%), and inadequate staff knowledge of pain management (61.4%) were the three most frequently cited barriers to physicians' pain management. Physicians' positive attitudes toward cancer pain management need to be encouraged, and active professional analgesic education programs are needed to improve pain management in China.

There is a gap in the literature about the influence of customer-oriented perception on nursing personnel's organizational citizenship behaviors. Organizational citizenship behaviors are the type of contextual behaviors that are difficult to observe and measure as such behaviors are usually generated in quite subtle and unpredictable ways. This study tested the hypothesis: Customer-oriented perception is associated with increased organizational citizenship behaviors for nurses. If nursing personnel's customer-oriented perception can increase their willingness to display organizational citizenship behaviors, it may facilitate hospital operation and enhance organizational effectiveness. A cross-sectional design using a questionnaire survey of nurses in 10 medical centers was used. Five hundred copies of the questionnaire were distributed, and 232 effective copies were retrieved, with a valid response rate of 46.4%. Structural equation modeling was performed in SPSS 11.0 and Amos 7.0 (SPSS Inc., Chicago, IL, USA) statistical software packages. The main finding was that favorable customer-oriented perception is associated with increased organizational citizenship behaviors for nurses. Extensive training and customer-oriented performance evaluation are proposed in the hope of creating customer-oriented perception among nursing personnel and subsequently inspiring the display of organizational citizenship behaviors. ©2010 Sigma Theta Tau International.

Meta-analyses of broad scope and complexity require investigators to organize many study documents and manage communication among several research staff. Commercially available electronic tools, e.g., EndNote, Adobe Acrobat Pro, Blackboard, Excel, and IBM SPSS Statistics (SPSS), are useful for organizing and tracking the meta-analytic process, as well as enhancing communication among research team members. The purpose of this paper is to describe the electronic processes we designed, using commercially available software, for an extensive quantitative model-testing meta-analysis we are conducting. Specific electronic tools improved the efficiency of (a) locating and screening studies, (b) screening and organizing studies and other project documents, (c) extracting data from primary studies, (d) checking data accuracy and analyses, and (e) communication among team members. The major limitation in designing and implementing a fully electronic system for meta-analysis was the requisite upfront time to: decide on which electronic tools to use, determine how these tools would be employed, develop clear guidelines for their use, and train members of the research team. The electronic process described here has been useful in streamlining the process of conducting this complex meta-analysis and enhancing communication and sharing documents among research team members.

To determine and compare the potential difference of nickel release from three different orthodontic brackets, in different artificial pH, in different time intervals. Twenty-seven samples of three different orthodontic brackets were selected and grouped as 1, 2, and 3. Each group was divided into three subgroups depending on the type of orthodontic brackets, salivary pH and the time interval. The Nickel release from each subgroup were analyzed by using inductively coupled plasma-Atomic Emission Spectrophotometer (Perkin Elmer, Optima 2100 DV, USA) model. Quantitative analysis of nickel was performed three times, and the mean value was used as result. ANOVA (F-test) was used to test the significant difference among the groups at 0.05 level of significance (P < 0.05). The descriptive method of statistics was used to calculate the mean, standard deviation, minimum and maximum. SPSS 18 software ((SPSS.Ltd, Quarry bay, Hong Kong, PASW-statistics 18) was used to analyze the study. The analysis shows a significant difference between three groups. The study shows that the nickel releases from the recycled stainless steel brackets have the highest at all 4.2 pH except in 120 h. The study result shows that the nickel release from the recycled stainless steel brackets is highest. Metal slot ceramic bracket release significantly less nickel. So, recycled stainless steel brackets should not be used for nickel allergic patients. Metal slot ceramic brackets are advisable.

Diabetes Mellitus is a metabolic disorder characterized by abnormal lipid and glucose metabolism. Various modes of adjuvant therapy have been advocated to ameliorate insulin resistance. This study was intended to assess the effects of antioxidants; alpha lipoic acid (ALA), omega 3 fatty acid and vitamin E on parameters of insulin sensitivity (blood glucose and HbA1c) in patients of type 2 diabetes mellitus with documented insulin resistance. It was a prospective, randomized, double blind, placebo controlled, single centered study. 104 patients with type 2 diabetes mellitus with insulin resistance were recruited. They were given ALA, omega 3 fatty acid, vitamin E or placebo. Fasting blood glucose and HbA1c were measured at first visit (V1) and after 90 days (V2). Statistical analysis was carried out by paired t-test by using SPSS software version 11 (SPSS, Chicago, USA). Analysis of baseline (V1) vs. end of treatment period (V2) parameters, showed significant decrease in HbA1c in the three treatment group. We also observed decrease in fasting blood glucose in the three treatment group but it was not statistically significant (Gr. I = 0.51, Gr. II = 0.05, Gr. III = 0.22, Gr. IV = 0.88). ALA, Omega 3 fatty acid and vitamin E can be used as add on therapy in patients with type 2 diabetes mellitus to improve insulin sensitivity and lipid metabolism.

The optimal approach is controversial in asymptomatic patients who are coincidentally found to have evidence of an accessory pathway (AP) on an ECG. The risk of sudden cardiac death (SCD) is low, and the risk of developing symptoms also appears to be low, although a wide range of incidences have been reported. In our trial, we tested the hypothesis that if prophylactic accessory-pathway ablation performed at the time of the initial electrophysiological testing would improve the long-term outcome in asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern. Recruitment of patients began on February 1, 2004, and ended on February 5, 2009. All 110 asymptomatic patients were hospitalized and underwent electrophysiological testing the same day to assess the inducibility of atrioventricular reciprocating tachycardia. The anterograde effective refractory period of the accessory pathway was defined as the longest coupling interval at which anterograde block in the bypass tract was observed. For the statistical analysis, the statistical software SPSS version 15.0 for Windows (SPSS Inc., Chicago, IL, USA). Of 110 asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern, 80 patients were ablated. Ablation group consisted of these patients. Control group consisted of remaining 30 and were divided into two groups according to the anterograde effective refractory period of the accessory pathway. There was no significant difference between three groups in terms of arrhythmic events (p: 0.58). Asymptomatic patients with the Wolff-Parkinson-White syndrome do not require prophylactic ablation, since they remain asymptomatic for many years.

College students are one of the most at-risk population groups for food poisoning, due to risky food safety behaviors. Using the Likert Scale, undergraduate students were asked to participate in a Food Safety Survey which was completed by 499 students ages 18–25. Data was analyzed using SPSS and AMOS statistical software. Four conceptual definitions regarding food safety were defined as: general food safety, bacterial food safety, produce food safety, and politics associated with food safety. Knowledge seems to be an important factor in shaping students attitudes regarding general and bacterial safety. Ethnicity plays a role in how people view the politics of food safety, and the safety of organic foods. PMID:23364131

In studying the urban complex issues, simulation and modelling of public space use considerably helps in determining and measuring factors such as urban safety. Depth map software for determining parameters of the spatial layout techniques; and Statistical Package for Social Sciences (SPSS) software for analysing and evaluating the views of the pedestrians on public safety were used in this study. Connectivity, integration, and depth of the area in the Tarbiat city blocks were measured using the Space Syntax Method, and these parameters are presented as graphical and mathematical data. The combination of the results obtained from the questionnaire and statistical analysis with the results of spatial arrangement technique represents the appropriate and inappropriate spaces for pedestrians. This method provides a useful and effective instrument for decision makers, planners, urban designers and programmers in order to evaluate public spaces in the city. Prior to physical modification of urban public spaces, space syntax simulates the pedestrian safety to be used as an analytical tool by the city management. Finally, regarding the modelled parameters and identification of different characteristics of the case, this study represents the strategies and policies in order to increase the safety of the pedestrians of Tarbiat in Tabriz.

Fixed orthodontic treatment is frequently associated with increased plaque accumulation leading to gingivitis and white spot lesions (WSLs). This study evaluated the role of text message reminder on oral hygiene of orthodontic patients. A total of 60 patients under fixed orthodontic treatment were randomly divided into two equal groups as control group and study (text message) group. Text message group received reminders about oral hygiene, while the control group did not receive any messages. Oral hygiene of both the groups was evaluated at baseline, 2, and 3 months using plaque indices (PIs) along with WSL status. Data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) statistical software, version 19, with chi-square test and t-test. At the baseline, plaque score was higher in the study group over control group (p > 0.038), whereas it was decreased after 3 months in the test group (p > 0.001). For WSL, there was no significant difference at baseline, but it was significantly lower in study group (p > 0.003). Oral hygiene status improved with text message reminder.

Several researches have been done on the measurement of angles of humeral torsion in different parts of the world. Previously described methods were more complicated, not much accurate, cumbersome or required sophisticated instruments. The present study was conducted with the aim to determine the angles of humeral torsion with a newer simple technique using digital images and image tool software. A total of 250 dry normal adult human humeri were obtained from the bone bank of Department of Anatomy. The length and mid-shaft circumference of each bone was measured with the help of measuring tape. The angle of humeral torsion was measured directly from the digital images by the image analysis using Image Tool 3.0 software program. The data was analysed statistically with SPSS version 17 using unpaired t-test and Spearman's rank order correlation coefficient. The mean angle of torsion was 64.57°±7.56°. On the right side it was 66.84°±9.69°, whereas, on the left side it was found to be 63.31±9.50°. The mean humeral length was 31.6 cm on right side and 30.33 cm on left side. Mid shaft circumference was 5.79 on right side and 5.63 cm on left side. No statistical differences were seen in angles between right and left humeri (p>0.001). From our study, it was concluded that circumference of shaft is inversely proportional to angle of humeral torsion. The length and side of humerus has no relation with the humeral torsion. With advancement of digital technology, it is better to use new image softwares for anatomical studies.

Aim: The aim of this study is to assess the caries risk assessment of 12–13-year-old government and private school going children of Mysore city using Cariogram. Materials and Methods: A cross-sectional examination was carried out on a total of 104 government and private schoolchildren aged 12–13 years. Ten factors from the Cariogram software(D Bratthall, Computer software, Malmo, Sweden) were included from study participant's records to complete the Cariogram. The percentage of “chances of avoiding new lesions” (caries risk) among government and private school study participants were obtained from Cariogram, and the participants were classified into five risk groups. Statistical analysis was performed using the software program Statistical Package of Social Science (version 17.0, SPSS Inc., Chicago IL, USA). Results: Findings revealed that there is slight difference in caries risk among government and private schoolchildren, where 48% caries risk development and 52% chance to avoid dental caries were showed in government schoolchildren, and 51% caries risk development and 49% chance to avoid dental caries were showed in private schoolchildren, according to Cariogram. Decayed, missing, and filled teeth component, mutans streptococci, and Lactobacillus counts were slightly higher in private schoolchildren compared with government schoolchildren. Conclusion: The private schoolchildren had less favorable values than government schoolchildren for most of the caries-related factors. Cariogram can be the most modest and reliable tool for caries prediction, thus aiding in identifying different risk groups in a community so that appropriate preventive strategies can be provided to overcome new carious lesion formation.

To assess the trend of changes in the evaluation scores of faculty members and discrepancy between administrators' and students' perspectives in a medical school from 2006 to 2015. This repeated cross-sectional study was conducted on the 10-year evaluation scores of all faculty members of a medical school (n=579) in an urban area of Iran. Data on evaluation scores given by students and administrators and the total of these scores were evaluated. Data were analyzed using descriptive and inferential statistics including linear mixed effect models for repeated measures via the SPSS software. There were statistically significant differences between the students' and administrators' perspectives over time ( p <0.001). The mean of the total evaluation scores also showed a statistically significant change over time ( p <0.001). Furthermore, the mean of changes over time in the total evaluation score between different departments was statistically significant ( p <0.001). The trend of changes in the student's evaluations was clear and positive, but the trend of administrators' evaluation was unclear. Since the evaluation of faculty members is affected by many other factors, there is a need for more future studies.

Postural instability is one of the most incapacitating symptoms of Parkinson's disease (PD) and appears to be related to cognitive deficits. This study aims to determine the cognitive factors that can predict deficits in static and dynamic balance in individuals with PD. A sociodemographic questionnaire characterized 52 individuals with PD for this work. The Trail Making Test, Rule Shift Cards Test, and Digit Span Test assessed the executive functions. The static balance was assessed using a plantar pressure platform, and dynamic balance was based on the Timed Up and Go Test. The results were statistically analysed using SPSS Statistics software through linear regression analysis. The results show that a statistically significant model based on cognitive outcomes was able to explain the variance of motor variables. Also, the explanatory value of the model tended to increase with the addition of individual and clinical variables, although the resulting model was not statistically significant The model explained 25-29% of the variability of the Timed Up and Go Test, while for the anteroposterior displacement it was 23-34%, and for the mediolateral displacement it was 24-39%. From the findings, we conclude that the cognitive performance, especially the executive functions, is a predictor of balance deficit in individuals with PD.

A required step for presenting results of clinical studies is the declaration of participants demographic and baseline characteristics as claimed by the FDAAA 801. The common workflow to accomplish this task is to export the clinical data from the used electronic data capture system and import it into statistical software like SAS software or IBM SPSS. This software requires trained users, who have to implement the analysis individually for each item. These expenditures may become an obstacle for small studies. Objective of this work is to design, implement and evaluate an open source application, called ODM Data Analysis, for the semi-automatic analysis of clinical study data. The system requires clinical data in the CDISC Operational Data Model format. After uploading the file, its syntax and data type conformity of the collected data is validated. The completeness of the study data is determined and basic statistics, including illustrative charts for each item, are generated. Datasets from four clinical studies have been used to evaluate the application's performance and functionality. The system is implemented as an open source web application (available at https://odmanalysis.uni-muenster.de) and also provided as Docker image which enables an easy distribution and installation on local systems. Study data is only stored in the application as long as the calculations are performed which is compliant with data protection endeavors. Analysis times are below half an hour, even for larger studies with over 6000 subjects. Medical experts have ensured the usefulness of this application to grant an overview of their collected study data for monitoring purposes and to generate descriptive statistics without further user interaction. The semi-automatic analysis has its limitations and cannot replace the complex analysis of statisticians, but it can be used as a starting point for their examination and reporting.

To evaluate the sedative effects, intra-operation, of music therapy in orthopedic surgery patients with locoregional anesthesia in the Hospital Clínic i Provincial of Barcelona. Prospective comparative study on a random sample of 110 patients undergoing or not music therapy. The degree of anxiety was assessed with the Questionnaire STAIC. The application of the music was done with a MP3 player and headphones. The collected data were analyzed with Excel. For the statistical analysis we used the SPSS-18 software and Chi-square test to test the hypothesis of whether there was relationship between the level of peace and music therapy. After the analysis, the results of Chi-square were in the group of no sedation with/without music Chi2 = 2.01, P = 0.35. The statistical significance level was p < 0.05. No relationship was found between hearing music or not and the patient's comfort level. Most patients recommend listening to music in the operating room despite the sounds around do not bother them.

Physicians have long recognized the association between diabetes mellitus and several pathologic conditions of the hand. The most commonly recognized maladies are limited joint mobility (LJM), Dupuytren's disease (DD), trigger finger (TF), and carpal tunnel syndrome (CTS). Incidence of these hand disorders has increased in the setting of diabetes. Collectively, these are described as diabetic hand syndrome. The aims were to find out the prevalence of hand disorders in diabetic patients, and to study the relation of these hand disorders with microvascular complications. This is an observational cross-sectional case-control study done over a period of 1 year Patients of type 2 DM, of age < 65 years, who visited Gandhi Memorial Hospital, Lucknow were enrolled and were described as cases. Age- and sex-matched nondiabetic individuals were taken in the control group. The data were analyzed using software SPSS. SPSS Inc. Released 2008. SPSS Statistics for Windows, Version 17.0. Chicago: SPSS Inc. Means and standard deviations were computed; the Student t-test and Chi-square (χ(2)) test were used as appropriate. A total of 400 subjects were studied, 200 each in the case and control groups. Of total 200 diabetic patients, 30% (60/200) patients had neuropathy, 37.5% (75/200) had nephropathy, and 44.5% (89/200) patients had retinopathy. In the study population, 67% patients were having one or more hand disorders, in which LJM was found in 40.5% (81/200) patients, DD was found in 19% (38/200) patients, TF in 16.5% (33/200), and CTS in 14% (28/200) patients. This study shows a high prevalence of hand disorders in diabetic patients and also correlates with the duration of type 2 DM, LJM being the most common hand disorder and more common in patients who have microvascular complications.

To investigate the effects of tissue engineered bone scaffold material in the restoration of alveolar socket after extraction of lower impacted third molar. Thirteen patients were immediately implanted with Bio-oss or PerioGlas® in the alveolar cavity after impacted mandibular third molar extraction. Clinical observation and X-ray were taken 1 to 12 weeks after operation. Paired t test was used for statistical analysis by SPSS10.0 software package. Thirteen patients did not experience postoperative complications. The distal alveolar height of the second molar and the gingival attachment did decrease significantly 1 to 12 weeks after operation(P < 0.05). Tissue engineered bone scaffold material is helpful in the restoration of alveolar socket after impacted third molar extraction.

Xpert MTB/RIF assay has revolutionized the diagnosis of tuberculosis (TB) by simultaneously detecting the bacteria and resistance to rifampicin (RIF), a surrogate marker for multidrug-resistant TB (MDR-TB) in <2 h. The RIF resistance pattern in Malwa region of Punjab, India, is not documented. Here, we report the epidemiology of RIF-resistant TB and mutations in rpoB gene of Mycobacterium tuberculosis (MTB). A total of 1612 specimens received between October 2013 and February 2015 were tested by Xpert MTB/RIF assay following manufacturer's instructions. The results thus obtained were analyzed using SPSS version 20.0.0 (SPSS Inc., Chicago, IL, USA) statistical software. RIF resistance was statistically higher in previously treated patients in comparison to the new patients (P = 0.006) and in patients with acid fast-Bacilli (AFB) positive smears to AFB-negative smears (P = 0.048). RIF resistance mutations in 130 specimens revealed frequency of E 73/130 (56%), B 28/130 (21.5%), D 18/130 (13.8%), A 11/130 (8.4%), and C 1/130 (0.7%) while in one specimen, mutation combination, i.e., mutations associated with more than one probe (A and B both) was present. Xpert MTB/RIF assay is a user-friendly screening tool for detection of MTB and RIF resistance from suspected TB/MDR cases in a shorter period of time. It could also serve as a useful technique to have simultaneous preliminary information regarding the mutation pattern of RIF resistance in MTB isolates.

To determine the occurrence of smile line and maxillary tooth shape in the Saudi Arabian subpopulation, and to estimate the association between these parameters with gingival biotype. On the fulfillment of selection criteria, total 315 patients belong to Saudi Arabian ethnic group were randomly selected. Two frontal photographs of the patients were acquired. The tooth morphology, gingival angle, and smile line classification were determined with ImageJ image analyzing software. The gingival biotype was assessed by probe transparency method. The obtained data were analyzed with SPSS 19 (IBM Corporation, New York, USA) software to determine the frequency and association between other parameters and gingival biotype. Among the clinical parameters evaluated, the tapering tooth morphology (56.8%), thick gingival biotype (53%), and average smile line (57.5%) was more prevalent. The statistically significant association was found between thick gingival biotype and the square tooth, high smile line. The high gingival angle was associated with thin gingival biotype. The study results indicate the existence of an association between tooth shape, smile line, and gingival angle with gingival biotype.

Age estimation of living or deceased individuals is an important aspect of forensic sciences. Conventionally, pulp-to-tooth area ratio (PTR) measured from periapical radiographs have been utilized as a nondestructive method of age estimation. Cone-beam computed tomography (CBCT) is a new method to acquire three-dimensional images of the teeth in living individuals. The present study investigated age estimation based on PTR of the maxillary canines measured in three planes obtained from CBCT image data. Sixty subjects aged 20-85 years were included in the study. For each tooth, mid-sagittal, mid-coronal, and three axial sections-cementoenamel junction (CEJ), one-fourth root level from CEJ, and mid-root-were assessed. PTR was calculated using AutoCAD software after outlining the pulp and tooth. All statistical analyses were performed using an SPSS 17.0 software program. Linear regression analysis showed that only PTR in axial plane at CEJ had significant age correlation ( r = 0.32; P < 0.05). This is probably because of clearer demarcation of pulp and tooth outline at this level.

Although psychological factors are now recognized as playing a significant and independent role in the development of coronary heart disease (CHD) and its complications, many of these factors are correlated with each other. The present study is aimed at examining the association between alexithymia and anxiety depression, stress, quality of life, and social support in CHD patients. In this research 398 patients with coronary heart disease (166 females and 232 males) from the city of Isfahan were selected using random sampling. The tools used included depression, anxiety, and stress scale (DASS-21), Health-related to Quality Of Life (HRQOL-26), Multiple Scale Perceived Social Support (MSPSS-12), and the Toronto Alexithymia Scale (TAS-20). The data were analyzed using structural equation modeling by using the Statistical Package for Social Science (SPSS21) (IBM Corp: Armonk, New York.U.S.) and Asset Management Operating System (AMOS21) SPSS, an IBM Company: Chicago, U.S. Software. Results of the structural equation model showed an acceptable goodness of fit, for the explanation alexithymia that was significantly associated with lower HRQOL and social support and increasing anxiety, depression, and stress. Alexithymia may increase anxiety, depression, and stress and can be a predisposing factor to poorer HRQOL and social support.

The aim of this study was to assess the correlation between the remaining dentin thickness (RDT) in deep decayed primary molars and the inflammatory status and bacterial composition of the corresponding coronal pulp. We hypothesized that RDT could be used as a reference for clinicians in assigning the indication for pulpotomy. Pulpotomies were conducted on the cameral pulp of 48 primary molars. Microorganisms, such as Lactobacillus sp., Streptococcus sp., and Prevotella sp., were identified and quantified and levels of tumor necrosis factor-alpha (TNF-α) and interlukin-6 (IL-6) were assessed. The correlation between the pre-operative RDT based on radiographic images and inflammatory-microbial profiles in vitro was evaluated using Spearman's rho correlation coefficient. All data analysis was performed using a statistical software program (SPSS 20.0, SPSS Inc., Chicago, IL, USA). Immunological and microbiological studies revealed elevated levels of TNF-α and IL-6 cytokines, and Lactobacillus sp., Streptococcus sp. and Prevotella sp. in the cameral pulp with an RDT measuring up to 1.1 mm. No significant relationship could be established between RDT, inflammatory status and microbial content of the pulps. The RDT remains a key clinical factor that needs to be assessed when establishing the indication for pulpotomy. Additional parameters that can improve this therapy should be investigated in the future.

Elderly cancer patients undergoing initial chemotherapy often suffer discomfort from medication-related symptom distress. This discomfort may affect treatment responses and outcomes negatively. This correlational, cross-sectional design study used a purposive sample of 100 patients who were both over 60 years of age and currently undergoing initial chemotherapy. The participants completed a structured questionnaire that was administered at a medical center in southern Taiwan. The questionnaire included a demographics datasheet, Coping Behavior Scale, and Symptom Distress Scale. Data was analyzed using descriptive statistics, Pearson's correlations, Mann-Whitney U, and Kruskal Wallis tests, which were run on SPSS 19.0 software. This correlational, cross-sectional design study used a purposive sample of 100 patients who were both over 60 years of age and currently undergoing initial chemotherapy. The participants completed a structured questionnaire that was administered at a medical center in southern Taiwan. The questionnaire included a demographics datasheet, Coping Behavior Scale, and Symptom Distress Scale. Data was analyzed using descriptive statistics, Pearson's correlations, Mann-Whitney U, and Kruskal Wallis tests, which were run on SPSS 19.0 software. Three-quarters (78%) of participants reported that they suffered from more than four distress symptoms. The top distress symptoms in terms of severity included: fatigue, poor appetite, insomnia, dry mouth, and altered bowel habits. The top distress symptoms in terms of frequency included: fatigue, dry mouth, poor appetite, insomnia, and altered bowel habits. "Problem-focused" coping was the most frequent type of coping behavior (mean = 3.19, SD = 0.24) that was used by participants. Furthermore, more frequent use of "emotions-focused" coping behaviors was associated with a greater risk of experiencing serious distress symptoms (r =.44, p < .001). Number of chronic diseases, cancer stage, and type of cancer treatment had no significant influence of symptom distress. Findings confirmed the relationship between coping behavior and symptom distress in elderly Taiwanese cancer patients undergoing initial chemotherapy. The results suggest that healthcare providers may use interventions that target patient coping behavior in order to alleviate the chemotherapy-induced symptoms of distress in elderly cancer patients.

Motivation is probably the most important factor that educators can target in order to improve learning. Numerous cross-disciplinary theories have been postulated to explain motivation. While each of these theories has some truth, no single theory seems to adequately explain all human motivation. The fact is that human beings in general and pupils in particular are complex creatures with complex needs and desires. In this paper, Analytic Hierarchy Process (AHP) has been proposed as an emerging solution to move towards too large, dynamic and complex real world multi-criteria decision making problems in selecting the most suitable motivator when choosing school for their children. Data were analyzed using SPSS 17.0 ("Statistical Package for Social Science") software. Statistic testing used are descriptive and inferential statistic. Descriptive statistic used to identify respondent pupils and parents demographic factors. The statistical testing used to determine the pupils and parents highest motivator priorities and parents' best priorities using AHP to determine the criteria chosen by parents such as school principals, teachers, pupils and parents. The moderating factors are selected schools based on "Standard Kualiti Pendidikan Malaysia" (SKPM) in Ampang. Inferential statistics such as One-way ANOVA used to get the significant and data used to calculate the weightage of AHP. School principals is found to be the best motivator for parents in choosing school for their pupils followed by teachers, parents and pupils.

AIM To evaluate the clinical and X-ray results of acetabular components and tantalum augments in prosthetic hip revisions. METHODS Fifty-eight hip prostheses with primary failure of the acetabular component were reviewed with tantalum implants. The clinical records and X-rays of these cases were retrospectively reviewed. Bone defect evaluations were based on preoperative CT scans and classified according to Paprosky criteria of Radiolucent lines and periprosthetic gaps; implant mobilization and osteolysis were evaluated by X-ray. An ad hoc database was created and statistical analyses were performed with SPSS software (IBM SPSS Statistics for Windows, version 23.0). Statistical analyses were carried out using the Student’s t test for independent and paired samples. A P value of < 0.05 was considered statistically significant and cumulative survival was calculated by the Kaplan-Meier method. RESULTS The mean follow-up was 87.6 ± 25.6 mo (range 3-120 mo). 25 cases (43.1%) were classified as minor defects, and 33 cases (56.9%) as major defects. The preoperative HHS rating improved significantly from a mean of 40.7 ± 6.1 (range: 29-53) before revision, to a mean of 85.8 ± 6.1 (range: 70-94) at the end of the follow-up (Student’s t test for paired samples: P < 0.001). Considering HHS only at the end of follow-up, no statistically significant difference was observed between patients with a major or minor defect (Student’s t test for independent samples: P > 0.05). Radiolucent lines were found in 4 implants (6.9%). Postoperative acetabular gaps were observed in 5 hips (8.6%). No signs of implant mobilization or areas of periprosthetic osteolysis were found in the x-rays at the final follow-up. Only 3 implants failed: 1 case of infection and 2 cases of instability. Defined as the end-point, cumulative survival at 10 years was 95% (for all reasons) and 100% for aseptic loosening of the acetabular component. CONCLUSION The medium-term use of prosthetic tantalum components in prosthetic hip revisions is safe and effective in a wide variety of acetabular bone defects. PMID:28808626

Although different methods are available for the analyses of longitudinal data, analyses based on generalized linear models (GLM) are criticized as violating the assumption of independence of observations. Alternatively, linear mixed models (LMM) are commonly used to understand changes in human behavior over time. In this paper, the basic concepts surrounding LMM (or hierarchical linear models) are outlined. Although SPSS is a statistical analyses package commonly used by researchers, documentation on LMM procedures in SPSS is not thorough or user friendly. With reference to this limitation, the related procedures for performing analyses based on LMM in SPSS are described. To demonstrate the application of LMM analyses in SPSS, findings based on six waves of data collected in the Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social Programmes) in Hong Kong are presented.

Aims: The aim of this study was to quantify the debris extruded apically from teeth using rotary and reciprocation instrumentation systems. Subjects and Methods: Eighty extracted human mandibular premolars with single canals and similar lengths were instrumented using ProTaper Universal (40, 06; Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Next (40, 06; Dentsply Maillefer, Ballaigues, Switzerland), WaveOne (40, 06; Dentsply Maillefer, Ballaigues, Switzerland), and Reciproc (R40; VDW GmbH, Munich, Germany). Debris extruded during instrumentation was collected into preweighed Eppendorf tubes, which were then stored in an incubator at 70°C for 5 days. The final weight of the Eppendorf tubes with the extruded debris was calculated after obtaining the mean of three consecutive weights obtained for each tube. Statistical Analysis Used: Statistical analysis was performed using SPSS version 16.0 software. The groups were compared using the Kruskal–Wallis test for all variables. Results: There was no statistically significant difference between the groups (P = 0.1114). However, the ProTaper Universal group produced more extrusion and ProTaper Next produced least debris extrusion among the instrument groups (P > 0.05). Conclusions: All instrumentation techniques were associated with extruded debris. PMID:28855755

To study the views of medical specialists on their attitude to and the resources for health research in Nigeria and draw appropriate policy implications. Structured questionnaires were distributed to consenting 90 randomly selected medical specialists practising in six Nigerian tertiary health institutions. Participants' background information, importance attached to research, motivations for conducting research, funding, ethical oversight, literature search, and statistical support were probed. The coded responses were stored and analyzed using the statistical SPSS software. Fifty-one out of the 90 questionnaires distributed were returned, giving a response rate of 63.3%. Research function was rated third by 64.7% of the respondents after hospital service (72.5%) and teaching (66.0%). Advancement of knowledge was the strongest motivating factor for conducting research (78.4%). Securing funding (94%) and finding time (80%) were their major constraints. Only a minority of the respondents, 20% and 14%, respectfully, positively rated the quality and promptness of the decisions of their institutions' ethical organs in the highest category. Most of their literature search was conducted on the internet (96.1%) and they stored and analyzed their research data with commonly available statistical software. Our study respondents regarded research highly but were severely constrained in conducting research by lack of access to sources of funding from within and outside Nigeria and finding time from core hospital functions. We recommend periodic (re)training in research particularly on how to apply for research grants and giving some protected research time for Nigerian medical specialists in order to boost their research function.

Objectives: The aim of this study was to analyze the histopathologically diagnosed cases of oral lichen planus (OLP) in terms of age, gender, clinical variant, site, hyperpigmentation, systemic illness, grade of dysplasia, and associated malignant transformation. This study also intended to do a review of reported cases of OLP with malignant transformation. Materials and Methods: One hundred and forty-three cases of histopathologically diagnosed OLP between 2010 and 2016 were retrospectively reviewed. Demographic and clinicopathological data including malignant transformation were obtained. The data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS) software for Windows version 20.0 (IBM SPSS, SPSS Inc., Chicago, IL, USA). A review of published literature on OLP with malignant transformation was also done from 1988 to 2017 and tabulated. Results: OLP in this study showed a male predilection with most of the patients in the third decade. The buccal mucosa (bilateral presentation) was the most common site (79.72%), and reticular type was the most common clinical type (79.02%) followed by erosive type (20.98%). The majority (92.31%) of cases were diagnosed with OLP without dysplasia. The rest (7.69%) of dysplastic cases were predominantly seen in the buccal mucosa of 58 years and above, female patients manifesting mainly as erosive type. Two patients (1.4%) previously diagnosed clinically and histopathologically as OLP developed oral squamous cell carcinoma. Conclusion: The present investigation revealed the predominance of OLP among middle-aged male population and the prevalence of bilateral involvement of buccal mucosa. Two of our cases showed malignant transformation over an average period of 3.5 years. The outcome of this study emphasizes the role of clinical follow-up of patients with OLP. PMID:28584781

The aim of this study was to analyze the histopathologically diagnosed cases of oral lichen planus (OLP) in terms of age, gender, clinical variant, site, hyperpigmentation, systemic illness, grade of dysplasia, and associated malignant transformation. This study also intended to do a review of reported cases of OLP with malignant transformation. One hundred and forty-three cases of histopathologically diagnosed OLP between 2010 and 2016 were retrospectively reviewed. Demographic and clinicopathological data including malignant transformation were obtained. The data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS) software for Windows version 20.0 (IBM SPSS, SPSS Inc., Chicago, IL, USA). A review of published literature on OLP with malignant transformation was also done from 1988 to 2017 and tabulated. OLP in this study showed a male predilection with most of the patients in the third decade. The buccal mucosa (bilateral presentation) was the most common site (79.72%), and reticular type was the most common clinical type (79.02%) followed by erosive type (20.98%). The majority (92.31%) of cases were diagnosed with OLP without dysplasia. The rest (7.69%) of dysplastic cases were predominantly seen in the buccal mucosa of 58 years and above, female patients manifesting mainly as erosive type. Two patients (1.4%) previously diagnosed clinically and histopathologically as OLP developed oral squamous cell carcinoma. The present investigation revealed the predominance of OLP among middle-aged male population and the prevalence of bilateral involvement of buccal mucosa. Two of our cases showed malignant transformation over an average period of 3.5 years. The outcome of this study emphasizes the role of clinical follow-up of patients with OLP.

To evaluate the esthetic outcomes of immediate single-tooth implant restoration in anterior maxilla with the pink esthetic score (PES). Nine patients were treated with 9 Straumann implants by immediate single-tooth implant restoration in anterior maxilla. Assessment of PES after crown placement at 1 week (baseline) and 6 months after implantation was conducted. Statistical analysis was performed using SPSS 16.0 software package. Nine implants achieved a retention rate of 100%. PES for single-tooth implant was 10.33 ± 1.50 at 1 week and 11.44 ± 0.88 at 6 months after crown placement. The difference was significant(P=0.021). This study indicates that immediate single-tooth implant restoration in anterior maxilla is predictable. Immediate single-tooth implantation can result in good clinical esthetic results in most patients with single-tooth missing in anterior maxilla.

Malware was designed to gain access or damage a computer system without user notice. Besides, attacker exploits malware to commit crime or fraud. This paper proposed Android malware classification approach based on K-Means clustering algorithm. We evaluate the proposed model in terms of accuracy using machine learning algorithms. Two datasets were selected to demonstrate the practicing of K-Means clustering algorithms that are Virus Total and Malgenome dataset. We classify the Android malware into three clusters which are ransomware, scareware and goodware. Nine features were considered for each types of dataset such as Lock Detected, Text Detected, Text Score, Encryption Detected, Threat, Porn, Law, Copyright and Moneypak. We used IBM SPSS Statistic software for data classification and WEKA tools to evaluate the built cluster. The proposed K-Means clustering algorithm shows promising result with high accuracy when tested using Random Forest algorithm.

In this study, the effects of Mannich bases containing bis-1,2,4-triazole on the levels of in vivo malondialdehyde (MDA) and antioxidant vitamins (A, E, C) were examined in serum, livers and kidneys of rats. DA and vitamin (A, E, C) levels were determined by high performance liquid chromatography (HPLC). Antioxidant effect was investigated by determining the MDA levels in Saccharomyces cerevisiae cells as in vitro. Furthermore, the antitumor effects of compounds were investigated against MCF-7 human breast cancer cells. Interrelations of results among control and compound groups were evaluated using SPSS statistical software package. As a result, some of the compounds showed effective biological activity when compared to control conditions. The test compounds used in this study may be effective for utilization in the selection and design of model compounds for further studies.

A rapid and cost-effective colorimetric sensor has been developed for the detection of bacteria (Bacillus subtilis was selected as an example). The sensor was designed to rely on lysozyme-capped AuNPs with the advantages of effective amplification and high specificity. In the sensing system, lysozyme was able to bind strongly to Bacillus subtilis, which effectively induced a color change of the solution from light purple to purplish red. The lowest concentration of Bacillus subtilis detectable by the naked eye was 4.5 × 10(3) colony-forming units (CFU) mL(-1). Similar results were discernable from UV-Vis absorption measurements. A good specificity was observed through a statistical analysis method using the SPSS software (version 17.0). This simple colorimetric sensor may therefore be a rapid and specific method for a bacterial detection assay in complex samples.

The Purdue Pharmacist Directive Guidance (PPDG) Scale was developed to assess patients' perceptions of the level of pharmacist-provided (1) instruction and (2) feedback and goal-setting-2 aspects of pharmaceutical care. Calculations of its psychometric properties stemming from SPSS and R were similar, but distinct differences were apparent. Using SPSS and R software packages, researchers aimed to examine the construct validity of the PPDG using a higher order factoring procedure; in tandem, McDonald's omega and Cronbach's alpha were calculated as means of reliability analyses. Ninety-nine patients with either type I or type II diabetes, aged 18 years or older, able to read and write English, and who could provide written-informed consent participated in the study. Data were collected in 8 community pharmacies in New Mexico. Using R, (1) a principal axis factor analysis with promax (oblique) rotation was conducted, (2) a Schmid-Leiman transformation was attained, and (3) McDonald's omega and Cronbach's alpha were computed. Using SPSS, subscale findings were validated by conducting a principal axis factor analysis with promax rotation; strict parallels and Cronbach's alpha reliabilities were calculated. McDonald's omega and Cronbach's alpha were robust, with coefficients greater than 0.90; principal axis factor analysis with promax rotation revealed construct similarities with an overall general factor emerging from R. Further subjecting the PPDG to rigorous psychometric testing revealed stronger quantitative support of the overall general factor of directive guidance and subscales of instruction and feedback and goal-setting.

Context: Junior doctors are reported to make most of the prescribing errors in the hospital setting. Aims: The aim of the following study is to determine the knowledge intern doctors have about prescribing errors and circumstances contributing to making them. Settings and Design: A structured questionnaire was distributed to intern doctors in National Hospital Abuja Nigeria. Subjects and Methods: Respondents gave information about their experience with prescribing medicines, the extent to which they agreed with the definition of a clinically meaningful prescribing error and events that constituted such. Their experience with prescribing certain categories of medicines was also sought. Statistical Analysis Used: Data was analyzed with Statistical Package for the Social Sciences (SPSS) software version 17 (SPSS Inc Chicago, Ill, USA). Chi-squared analysis contrasted differences in proportions; P < 0.05 was considered to be statistically significant. Results: The response rate was 90.9% and 27 (90%) had <1 year of prescribing experience. 17 (56.7%) respondents totally agreed with the definition of a clinically meaningful prescribing error. Most common reasons for prescribing mistakes were a failure to check prescriptions with a reference source (14, 25.5%) and failure to check for adverse drug interactions (14, 25.5%). Omitting some essential information such as duration of therapy (13, 20%), patient age (14, 21.5%) and dosage errors (14, 21.5%) were the most common types of prescribing errors made. Respondents considered workload (23, 76.7%), multitasking (19, 63.3%), rushing (18, 60.0%) and tiredness/stress (16, 53.3%) as important factors contributing to prescribing errors. Interns were least confident prescribing antibiotics (12, 25.5%), opioid analgesics (12, 25.5%) cytotoxics (10, 21.3%) and antipsychotics (9, 19.1%) unsupervised. Conclusions: Respondents seemed to have a low awareness of making prescribing errors. Principles of rational prescribing and events that constitute prescribing errors should be taught in the practice setting. PMID:24808682

To evaluate the frequent use of ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland) systems on shaping ability of root canal utilizing Solidworks (2014, Dassault Systemes) software. Thirty-six root canals in clear resin blocks (Dentsply-Maillefer) were allocated into six experimental groups (n = 36). Six new sets of PTN instruments (Dentsply Maillefer, Ballaigues, Switzerland) were used six times to shape the resin blocks. A #15 K-file was inserted to the working length (WL), followed by ProGlider (PG) to create a glide path. Sequential use of PTN instrumentation in a crown-down technique was used to reach size (30/07) apically. Macroscopic photos of the blocks were taken before and after instrumentation, layered by Paint Shop Pro 9 from JascSoftware, and then canal transportation was measured using Solidwork 2014. The data were analyzed by SPSS software version 22. Multivariate statistical analysis general linear model (GLM) was also applied. Bonferroni correction test was used in multiple comparisons and the statistical significance was set to 0.05. There was no difference in canal transportation resulted from utilizing PTN files after six multiple uses; in addition, the PTN files showed ability to maintain the original canal anatomy, especially in the apical level, where lowest total mean value of canal center displacement was seen (3 mm level) (0.019 ± 0.017). ProTaper Next files can be used to prepare single and multiple canals in a single furcated tooth. ProTaper Next nickel-titanium (NiTi) file system is a safe instrument that respects the canal shape, allows practitioners to treat difficult cases with good results, and low risk of separation.

Introduction: Acanthosis nigricans (AN) is a frequently encountered entity. Facial AN (FAN) is a subset of AN which is being increasingly recognized. Recently, reports hypothesizing the association of FAN with features of metabolic syndrome have been published. Aims and Objectives: The aim of this study was to study the clinicodemographic profile of patients with FAN, and to assess the correlation of hypertension, increased waist–hip ratio (WHR), increased body mass index (BMI), type 2 diabetes mellitus, deranged lipid profile, serum insulin, and impaired oral glucose tolerance test (OGTT) (parameters of metabolic syndrome) in these patients, as well as to determine the most significant predictor (highest relative risk) of development of FAN. Methods: A multicentric case–control study was conducted (123 cases in each group) over a period of 2 years. Data were obtained on the basis of history, examination, and relevant laboratory investigations. Statistical analysis was done using Statistica version 6 (StatSoft Inc., 2001, Tulsa, Oklahoma, USA), SPSS statistics version 17 (SPSS Inc., 2008, Illinois, Chicago, USA), and GraphPad Prism version 5 (GraphPad Software Inc., 2007, San Diego, California, USA). Results: Mean age of the patients with FAN was 38.83 ± 8.62 years. Mean age of onset of the disease was 30.93 ± 8.18 years. The most common site of face involved was the forehead and temporal region. The most common pigmentation was brown-black. Male sex, positive OGTT, increased WHR, and increased BMI were most significantly related to FAN. Smoking was found to have a protective effect against the development of FAN. Conclusion: Here, we document a significant association between male patients with positive OGTT, increased WHR, and BMI and FAN. Thus, we propose that FAN could be considered a morphological marker of metabolic syndrome. PMID:29263532

The change in neurosensory lesions that develop after bilateral sagittal split osteotomy (BSSO) was explored, and the influence of the application of combination uridine triphosphate (UTP), cytidine monophosphate (CMP), and hydroxycobalamin (vitamin B12) on patient outcomes was assessed. This was a randomized, controlled, double-blind trial. The study sample comprised 12 patients, each evaluated on both sides (thus 24 sides). All patients fulfilled defined selection criteria. Changes in the lesions were measured both subjectively and objectively. The sample was divided into two patient groups: an experimental group receiving medication and a control group receiving placebo. The statistical analysis was performed using SPSS software. Lesions in both groups improved and no statistically significant difference between the groups was observed at any time. 'Severe' injuries in the experimental group were more likely to exhibit a significant improvement after 6 months. Based on the results of the present study, it is concluded that the combination UTP, CMP, and hydroxycobalamin did not influence recovery from neurosensory disorders. Copyright © 2015.

OBJECTIVE To analyze the relationship between gender violence and suicidal ideation in women with HIV. METHODS A cross-sectional study with 161 users of specialized HIV/AIDS care services. The study investigated the presence of gender violence through the Brazilian version of the World Health Organization Violence against Women instrument, and suicidal ideation through the Suicidal Ideation Questionnaire. Statistical analyses were performed with the SPSS software, using the Chi-square test and Poisson multiple regression model. RESULTS Eighty-two women with HIV reported suicidal ideation (50.0%), 78 (95.0%) of who had suffered gender violence. Age at first sexual intercourse < 15 years old, high number of children, poverty, living with HIV for long, and presence of violence were statistically associated with suicidal ideation. Women who suffered gender violence showed 5.7 times more risk of manifesting suicidal ideation. CONCLUSIONS Women with HIV showed a high prevalence to gender violence and suicidal ideation. Understanding the relationship between these two grievances may contribute to the comprehensive care of these women and implementation of actions to prevent violence and suicide. PMID:25372166

Organizational learning is defined as creating, absorbing, retaining, transferring, and application of knowledge within an organization. This article aims to examine the mediating role of organizational learning in the relationship of organizational intelligence and organizational agility. This analytical and cross-sectional study was conducted in 2015 at four teaching hospitals of Yazd city, Iran. A total of 370 administrative and medical staff contributed to the study. We used stratified-random method for sampling. Required data were gathered using three valid questionnaires including Alberkht (2003) organizational intelligence, Neefe (2001) organizational learning, and Sharifi and Zhang (1999) organizational agility questionnaires. Data analysis was done through R and SPSS 18 statistical software. The results showed that organizational learning acts as a mediator in the relationship of organizational intelligence and organizational agility (path coefficient = 0.943). Also, organizational learning has a statistical relationship with organizational agility (path coefficient = 0.382). Our findings suggest that the improvement of organizational learning abilities can affect an organization's agility which is crucial for its survival.

Sophisticated univariate outlier screening procedures are not yet available in widely used statistical packages such as SPSS. However, SPSS can accept user-supplied programs for executing these procedures. Failing this, researchers tend to rely on simplistic alternatives that can distort data because they do not adjust to cell-specific characteristics. Despite their popularity, these simple procedures may be especially ill suited for some applications (e.g., data from reaction time experiments). A user friendly SPSS Production Facility implementation of the shifting z score criterion procedure (Van Selst & Jolicoeur, 1994) is presented in an attempt to make it easier to use. In addition to outlier screening, optional syntax modules can be added that will perform tedious database management tasks (e.g., restructuring or computing means).

Overweight and obesity are a public health problem in India not only in adults but also in children. The authors sought to estimate the prevalence of overweight and obesity in school-going children of 6-17 years of age and examine its demographic and dietary correlates in context of their urban-rural status and socio-economic status. In this cross-sectional survey height and weight were measured in 1266 school children in government and private schools of urban and rural areas. Dietary assessment was done using single day 24-hour dietary recall method. The data were analyzed using SPSS (IBM SPSS Statistics Version 19) and WHO AnthroPlus Software. Factorial ANOVA was used for testing interaction within and between subgroups for continuous variables and Chi-square test was used for categorical variables. It was found that the overall prevalence of overweight was 15.6% of which 5.4% were obese, with maximum prevalence in boys attending urban private schools. The mean caloric intake in the study population with 24-hour dietary recall method was 1558.2 kilocalories (SD: 428 kilocalories). Overweight and obesity is a significant problem in school-going children. Higher socio-economic status continues to remain an important driver of this epidemic in the younger generation and affects demographic and dietary determinants of this problem.

Aims and Objectives: The aim of this study was to assess the correlation between the remaining dentin thickness (RDT) in deep decayed primary molars and the inflammatory status and bacterial composition of the corresponding coronal pulp. We hypothesized that RDT could be used as a reference for clinicians in assigning the indication for pulpotomy. Materials and Methods: Pulpotomies were conducted on the cameral pulp of 48 primary molars. Microorganisms, such as Lactobacillus sp., Streptococcus sp., and Prevotella sp., were identified and quantified and levels of tumor necrosis factor-alpha (TNF-α) and interlukin-6 (IL-6) were assessed. The correlation between the pre-operative RDT based on radiographic images and inflammatory-microbial profiles in vitro was evaluated using Spearman's rho correlation coefficient. All data analysis was performed using a statistical software program (SPSS 20.0, SPSS Inc., Chicago, IL, USA). Results: Immunological and microbiological studies revealed elevated levels of TNF-α and IL-6 cytokines, and Lactobacillus sp., Streptococcus sp. and Prevotella sp. in the cameral pulp with an RDT measuring up to 1.1 mm. No significant relationship could be established between RDT, inflammatory status and microbial content of the pulps. Conclusion: The RDT remains a key clinical factor that needs to be assessed when establishing the indication for pulpotomy. Additional parameters that can improve this therapy should be investigated in the future. PMID:29026700

This article contains data collected from self-report surveys of respondents to measure 1) social media usage, 2) age, 3) gender and 4) trust, measured within five major trust constructs of a) Integrity, b) Competence, c) Concern, d) Benevolence and e) Identification. The data includes all instruments used, SPSS syntax, the raw survey data and descriptive statistics from the analyses. Raw data was entered into SPSS software and scrubbed using appropriate techniques in order to prepare the data for analysis. We believe that our dataset and instrument may give important insights related to computers in human behavior, and predicting trust antecedents in social media use such as age, gender, number of hour online and choice of content provider. We have also created a parsimonious five factor trust instrument developed from the extant literature for future research. Hence, this newly developed trust instrument can be used to measure trust not only in social media, but also in other areas such as healthcare, economics and investor relations, CSR, management and education. Moreover, the survey items developed to measure social media use are concise and may be applied to measure social media use in other contexts such as national cultural differences, marketing and tourism. For interpretation and discussion of the data and constructs, please see original article entitled "Who trusts social media" (Warner-Søderholm et al., 2018) [1].

2016-04-01

Hand-assisted laparoscopic nephrectomy is a relatively new procedure in our country. This article reports on one of the largest number of this procedure in kidneys with multiple vessels. We reviewed all cases of hand-assisted laparoscopic nephrectomy from July 2002 to February 2009. Results were then descriptive, with statistical analyses performed with SPSS software (SPSS: An IBM Company, version 10.0, IBM Corporation, Armonk, NY, USA). From July 2002 to February 2009, 165 patients had hand-assisted laparoscopic nephrectomy, with 96.9% being the left kidney. We found a prevalence of 18.7% (n = 31) of kidneys with multiple arteries, with 8 of these having multiple principal arteries, 9 with superior polar artery, and 14 with inferior polar artery. Twenty-nine donors (17.57%) presented with more than 1 principal vein. Warm ischemia was longer in kidneys with multiple arteries (4.16 vs 3.96 min); recipient renal function (evaluated by creatinine levels at day 5 after transplant) was 1.63 mg/dL in kidneys with single artery versus 1.27 mg/dL in kidneys with multiple arteries. There were no significant differences for time of surgery, bleeding, and discharge of the donor. We found no differences in kidney function between single and multiple artery kidneys, resulting in the conclusion that hand-assisted laparoscopic nephrectomy offers an effective option for kidney donors, including those with multiple arteries.

It is associated with considerable morbidity and mortality due to widespread use of antibiotics. The study was done to determine the prevalence of C. difficile infection (CDI) among the patients attending a tertiary care teaching hospital in Puducherry. We performed a prospective cohort study in Mahatma Gandhi Medical College and Research Institute. Around 150 patients were evaluated along with the patient details. C. difficile toxin detection was done as per the standard algorithm using the C. Diff Quik Chek Complete® assay (TECHLAB, Blacksburg, VA, USA). Analysis was done using statistics software (SPSS 16.0, SPSS Inc., Chicago, IL, USA). The prevalence of CDI was found to be 4%. More toxin-positive cases were between 50 and 60 years of age, and there was no difference in gender. Intensive Care Unit showed more toxin-positive cases; however, there was no significant association between the occurrence of CDI and the primary diagnosis of the patients. The prevalence of CDI in our hospital was found to be 4%, which was relatively lower compared to other Indian studies. However, awareness of the risk factors may assist in identifying patients at higher risk for CDI, guide implementation of appropriate preventive measures, and modulate potential intervention measure during management.

Background: Vulvovaginal candidiasis (VVC) remains a common problem worldwide and the role of douching as a predisposing factor is unclear. Aim: This study was undertaken to highlight the prevalence and predisposing factors of VVC in North-west Nigeria. Subjects and Methods: This was a prospective study done at Aminu Kano Teaching Hospital (AKTH), North-west. AKTH is a 500-bed tertiary hospital located in Kano, the most populous state in Nigeria. Ethical clearance was obtained. Three hundred patients with VVC were recruited from the gynecologic and general outpatients’ clinics of AKTH. Research structured questionnaires were used to obtain sociodemographic and clinical information. The data obtained were analyzed using SPSS version 16.0 statistical software (SPSS Inc., Chicago IL, USA). Frequency, mean and simple percentages were used to analyze data. Result: Candida albicans was the most frequent cause of the positive high vaginal swabs constituting 84.5% (316/374) while Proteus vulgaris was the least frequent cause constituting 0.53% (2/374). Fifty-three percent (143/270) of those with VVC were aged 26–35 years; the married were 80% (216/270) and those who were unmarried were 20% (54/270). Douching was the commonest predisposing factor occurring in 42.5% (115/270) of cases. Conclusion: VVC was the most prevalent cause of vaginosis in North-west Nigeria, and douching was the commonest predisposing factor. PMID:26229716

The efficiency of civil engineering structure require comprehensive geotechnical data obtained from site investigation. In the past, conventional site investigation was heavily related to drilling techniques thus suffer from several limitations such as time consuming, expensive and limited data collection. Consequently, this study presents determination of soil moisture content using laboratory experimental and field electrical resistivity values (ERV). Field and laboratory electrical resistivity (ER) test were performed using ABEM SAS4000 and Nilsson400 soil resistance meter. Soil sample used for resistivity test was tested for characterization test specifically on particle size distribution and moisture content test according to BS1377 (1990). Field ER data was processed using RES2DINV software while laboratory ER data was analyzed using SPSS and Excel software. Correlation of ERV and moisture content shows some medium relationship due to its r = 0.506. Moreover, coefficient of determination, R2 analyzed has demonstrate that the statistical correlation obtain was very good due to its R2 value of 0.9382. In order to determine soil moisture content based on statistical correlation (w = 110.68ρ-0.347), correction factor, C was established through laboratory and field ERV given as 19.27. Finally, this study has shown that soil basic geotechnical properties with particular reference to water content was applicably determined using integration of laboratory and field ERV data analysis thus able to compliment conventional approach due to its economic, fast and wider data coverage.

Productivity has often been cited as a key factor in a flexible manufacturing system (FMS) performance, and actions to increase it are said to improve profitability and the wage earning capacity of employees. Improving productivity is seen as a key issue for survival and success in the long term of a manufacturing system. The purpose of this paper is to make a model and analysis of the productivity variables of FMS. This study was performed by different approaches viz. interpretive structural modelling (ISM), structural equation modelling (SEM), graph theory and matrix approach (GTMA) and a cross-sectional survey within manufacturing firms in India. ISM has been used to develop a model of productivity variables, and then it has been analyzed. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are powerful statistical techniques. CFA is carried by SEM. EFA is applied to extract the factors in FMS by the statistical package for social sciences (SPSS 20) software and confirming these factors by CFA through analysis of moment structures (AMOS 20) software. The twenty productivity variables are identified through literature and four factors extracted, which involves the productivity of FMS. The four factors are people, quality, machine and flexibility. SEM using AMOS 20 was used to perform the first order four-factor structures. GTMA is a multiple attribute decision making (MADM) methodology used to find intensity/quantification of productivity variables in an organization. The FMS productivity index has purposed to intensify the factors which affect FMS.

The aim of this study was to investigate the expression of CD44 and its clinical significance in children suffering from hepatoblastoma (HB). CD44 expression was detected with immunohistochemistry staining in 30 samples from hepatoblastoma children and 10 normal liver tissue samples from normal children. The data obtained was statistically analyzed using the chi-square test, using the SPSS (v.11.0) software. The rate of CD44 expression was significantly higher (66.7%) in hepatoblastoma tissues than in normal liver tissues (χ(2) = 4.848, P < 0.05). The rate of CD44 expression was significantly higher in children with stage III or IV hepatoblastoma (83.3%) than that in children with stage I and II hepatoblastoma (χ(2) ＝ 5.625, P < 0.05) (41.7%). Therefore, CD44 expression might play an important role in the pathogenesis, progression, and prognosis of HB in children.

Single-case experimental designs are useful methods in clinical research practice to investigate individual client progress. Their proliferation might have been hampered by methodological challenges such as the difficulty applying existing statistical procedures. In this article, we describe a data-analytic method to analyze univariate (i.e., one symptom) single-case data using the common package SPSS. This method can help the clinical researcher to investigate whether an intervention works as compared with a baseline period or another intervention type, and to determine whether symptom improvement is clinically significant. First, we describe the statistical method in a conceptual way and show how it can be implemented in SPSS. Simulation studies were performed to determine the number of observation points required per intervention phase. Second, to illustrate this method and its implications, we present a case study of an adolescent with anxiety disorders treated with cognitive-behavioral therapy techniques in an outpatient psychotherapy clinic, whose symptoms were regularly assessed before each session. We provide a description of the data analyses and results of this case study. Finally, we discuss the advantages and shortcomings of the proposed method. Copyright © 2014. Published by Elsevier Ltd.

2010-09-01

This study focuses on landslide susceptibility mapping in the Daunia area (Apulian Apennines, Italy) and achieves this by using a multivariate statistical method and data processing in a Geographical Information System (GIS). The Logistic Regression (hereafter LR) method was chosen to produce a susceptibility map over an area of 130 000 ha where small settlements are historically threatened by landslide phenomena. By means of LR analysis, the tendency to landslide occurrences was, therefore, assessed by relating a landslide inventory (dependent variable) to a series of causal factors (independent variables) which were managed in the GIS, while the statistical analyses were performed by means of the SPSS (Statistical Package for the Social Sciences) software. The LR analysis produced a reliable susceptibility map of the investigated area and the probability level of landslide occurrence was ranked in four classes. The overall performance achieved by the LR analysis was assessed by local comparison between the expected susceptibility and an independent dataset extrapolated from the landslide inventory. Of the samples classified as susceptible to landslide occurrences, 85% correspond to areas where landslide phenomena have actually occurred. In addition, the consideration of the regression coefficients provided by the analysis demonstrated that a major role is played by the "land cover" and "lithology" causal factors in determining the occurrence and distribution of landslide phenomena in the Apulian Apennines.

BACKGROUND: Surrogacy is a popular form of assisted reproductive technology of which only gestational form is approved by most of the religious scholars in Iran. Little evidence exists about the Iranian infertile women's viewpoint regarding gestational surrogacy. AIM: To assess the viewpoint of Iranian infertile women toward gestational surrogacy. SETTING AND DESIGN: This descriptive study was conducted at the infertility clinic of Tabriz University of Medical Sciences, Iran. MATERIALS AND METHODS: The study sample consisted of 238 infertile women who were selected using the eligible sampling method. Data were collected by using a researcher developed questionnaire that included 25 items based on a five-point Likert scale. STATISTICAL ANALYSIS: Data analysis was conducted by SPSS statistical software using descriptive statistics. RESULTS: Viewpoint of 214 women (89.9%) was positive. 36 (15.1%) women considered gestational surrogacy against their religious beliefs; 170 women (71.4%) did not assume the commissioning couple as owners of the baby; 160 women (67.2%) said that children who were born through surrogacy would better not know about it; and 174 women (73.1%) believed that children born through surrogacy will face mental problems. CONCLUSION: Iranian infertile women have positive viewpoint regarding the surrogacy. However, to increase the acceptability of surrogacy among infertile women, further efforts are needed.

The aim of the study was to evaluate the cervical vertebral maturation and dental age, in group of patients with coelic disease (CD), in comparison with a control group of healthy subjects. At the Paediatric Dentistry Unit of PTV Hospital, "Tor Vergata" University of Rome, 120 female patients, age range 12.0-12.9 years were recruited. Among them, 60 subjects (Group 1) were affected by CD, while the control group (Group 2) consisted of 60 healthy subjects, sex and age-matched. The Group 1 was subdivided, according to the period of CD diagnosis, in Group A (early diagnosis) and Group B (late diagnosis). The skeletal age was determined by assessing the cervical vertebral maturation, while the dental age has been determined using the method codified by Demirjiyan. STATISTICS.: The analyses were performed using the SPSS software (version 16; SPSS Inc., Chicago IL, USA). In all the assessments a significant level of alpha = 0.05 was considered. There are no statistically significant differences between Group 1 and Group 2 as for chronological age (p=0.122). Instead, from the assessment of skeletal-dental age, there are statistically significant differences between Group 1 - Group 2 (p<0.001) and Group A - Group B (p<0.001). The statistical analysis carried out to assess the differences between chronological and skeletal-dental age within the single groups, show a statistically significant difference in Group 1 (p<0.001) and in Group B (p<0.001), while there are no statistically significant differences in Group 2 (p=0.538) and in Group A (p=0.475). A correlation between skeletal and dental age was registered; for Groups 1-2 and for Groups A-B the Pearson coefficient was respectively equal to 0.967 and 0.969, with p<0.001. Through the analysis of data it is possible to assess that the percentage of subjects with skeletal and dental age delay corresponds to 20% in healthy subjects, 56.7% in coeliac subjects, 23% in coeliac subjects with early diagnosis and 90% in coeliac subjects with late diagnosis. From the comparison between Group 2 and Group A there are no statistically significant differences (p=0.951). Conclusions. The skeletal age and dental age delay may be two predictive indexes for a CD diagnosis. The dental age and cervical vertebral maturity can be assessed with a low cost, non invasive, easy to perform exam carried out through the routine radiographic examinations such as orthopanoramic and lateral teleradiography.

To assess the awareness, attitude, and knowledge about basic life support (BLS) among medical, dental, and nursing students and faculties and the proposal of BLS skills in the academic curriculum of undergraduate (UG) course. Recognition, prevention, and effective management of life-threatening emergencies are the responsibility of health-care professionals. These situations can be successfully managed by proper knowledge and training of the BLS skills. These life-saving maneuvers can be given through the structured resuscitation programs, which are lacking in the academic curriculum. A questionnaire study consisting of 20 questions was conducted among 659 participants in the Kalinga Institute of Dental Sciences, Kalinga Institute of Medical Sciences, KIIT University. Medical junior residents, BDS faculties, interns, nursing faculties, and 3 rd -year and final-year UG students from both medical and dental colleges were chosen. The statistical analysis was carried out using SPSS software version 20.0 (Armonk, NY:IBM Corp). After collecting the data, the values were statistically analyzed and tabulated. Statistical analysis was performed using Mann-Whitney U-test. The results with P < 0.05 were considered statistically significant. Our participants were aware of BLS, showed positive attitude toward it, whereas the knowledge about BLS was lacking, with the statistically significant P value. By introducing BLS regularly in the academic curriculum and by routine hands on workshops, all the health-care providers should be well versed with the BLS skills for effectively managing the life-threatening emergencies.

Recent research describes the use of a nerve root sedimentation sign to diagnose lumbar spinal stenosis (LSS). The lack of sedimentation of the nerve roots (positive sedimentation sign) to the dorsal part of the dural sac is the characteristic feature of this new radiological parameter. To demonstrate how the nerve root sedimentation sign compares with other more traditional radiological parameters in patients who have been operated for LSS. A retrospective chart and image review. Preoperative magnetic resonance images (MRIs) were reviewed from 71 consecutive operative patients who presented with LSS and received spinal decompression surgery from 2006 to 2010. Preoperative T2-weighted MRIs were reviewed for each patient. One hundred thirty-four vertebral levels from L1 to L5 were measured for: sedimentation sign, cross-sectional area (CSA) and anterior/posterior (A/P) diameter of the dural sac, thickness of the ligamentum flavum, and Fujiwara grade of facet hypertrophy. Radiological measurements were made using Surgimap 1.1.2.169 software (Nemaris, Inc., New York, NY, USA). Statistical analyses were performed using the SPSS 17.0 statistical software (SPSS Inc., Chicago, IL, USA). Significance was demonstrated using unpaired t tests and chi-squared tests. Study funding was departmental. There were no study-specific conflicts of interest-associated biases. A positive sedimentation sign was determined in 120 operated levels (89.5%), whereas 14 levels (10.5%) had no sign (negative sedimentation sign). The mean CSA and A/P diameter were 140.62 mm(2) (standard deviation [SD]=53) and 11.76 mm (SD=3), respectively, for the no-sign group; the mean CSA and A/P diameter were 81.87 mm(2) (SD=35) and 8.76 mm (SD=2.2), respectively, for the sedimentation sign group (p<.001). We found that 60% of levels with Fujiwara Grade A facet hypertrophy did not have a sedimentation sign, whereas 86.3% of levels with Grade B, 93.2% of levels with Grade C, and 100.0% of levels with Grade D did have a sedimentation sign (p<.001). The sedimentation sign is a new measurement tool that can enable physicians to objectively assess and quantify spinal stenosis. The sign is most often present in patients who have clinically significant lumbar stenosis and require surgery. Copyright © 2013 Elsevier Inc. All rights reserved.

The mainstay of diagnosis of osteoporosis is dual-energy X-ray absorptiometry (DXA) scan measuring areal bone mineral density (BMD) (g/cm 2 ). The aim of the present study was to compare the Indian Council of Medical Research database (ICMRD) and the Lunar ethnic reference database of DXA scans in the diagnosis of osteoporosis in male patients. In this retrospective study, all male patients who underwent a DXA scan were included. The areal BMD (g/cm 2 ) was measured at either the lumbar spine (L1-L4) or the total hip using the Lunar DXA machine (software version 8.50) manufactured by GE Medical Systems (Shanghai, China). The Indian Council of Medical Research published a reference data for BMD in the Indian population derived from the population-based study conducted in healthy Indian individuals, which was used to analyze the BMD result by Lunar DXA scan. The 2 results were compared for various values using statistical software SPSS for Windows (version 16; SPSS Inc., Chicago, IL). A total 238 male patients with a mean age of 57.2 yr (standard deviation ±15.9) were included. Overall, 26.4% (66/250) and 2.8% (7/250) of the subjects were classified in the osteoporosis group according to the Lunar database and the ICMRD, respectively. Out of the 250 sites of the DXA scan, 28.8% (19/66) and 60.0% (40/66) of the cases classified as osteoporosis by the Lunar database were reclassified as normal and osteopenia by ICMRD, respectively. In conclusion, the Indian Council of Medical Research data underestimated the degree of osteoporosis in male subjects that might result in deferring of treatment. In view of the discrepancy, the decision on the treatment of osteoporosis should be based on the multiple fracture risk factors and less reliably on the BMD T-score.

Increasing incidence of adenocarcinoma lung in India: Following the global trend?

PubMed

Mohan, A; Latifi, A N; Guleria, R

2016-01-01

Lung cancer is one of the most common malignant neoplasms worldwide and accounts for more deaths than any other cancer. The clinicopathological profile of lung cancer has shown marked regional and geographical variation. We aimed to compare the demographic and pathological profile of lung cancer patients from North India with other Indian and International series. A retrospective study over a period of 5 years from January 2008 to May 2013 was conducted in the Department of Pulmonary Medicine and Sleep Disorders, All India Institute of Medical Sciences, New Delhi. A total of 397 newly diagnosed patients with lung cancer from January 2008 to May 2013 were included in the study. The clinical, demographic, and pathological features were reviewed and compared with other major National and International reports. Data were entered and analyzed using SPSS software (SPSS Inc. Released 2009. PASW Statistics for Windows, Version 18.0. Chicago: SPSS Inc. A total of 397 patients (86% men, mean age 57.8 years) were studied. The ratio of men to women was 7.4. Majority of patients (78.3%) were current/previous smokers. Small cell carcinoma was diagnosed in 14.6% (58) of patients while 85.4% (339) had nonsmall cell lung carcinoma (NSCLC). Within NSCLC, the most common histology types were squamous cell carcinoma (30%), followed closely by adenocarcinoma (ADC) (28.3%) and large cell carcinoma (1.7%). Majority (87%) of the patient were staged III and IV. About 30.1% patients received anti-tubercular treatment during the current episode before a diagnosis of lung cancer was made. The clinicopathological profile of lung cancer has undergone noticeable changes over the last four decades, especially in the increase in ADC incidence and their frequent presence in smokers. Lung cancer is often mistreated as tuberculosis in the Indian subcontinent and hence continues to be diagnosed late.

The objective of this study was to determine the prevalence of road traffic crashes (RTC)-related maxillofacial injuries, the concomitant injuries occurring with them, and to assess the relationship between the severity of maxillofacial and concomitant injuries. This was a prospective study involving 201 victims of RTC seen at the Accident and Emergency Department of the University College Hospital, Ibadan with maxillofacial injuries during the study period. Demographic data of the patients, the types of maxillofacial injuries, and concomitant injuries sustained were recorded. Severity of maxillofacial injury was determined using the maxillofacial injury severity scale (MFISS), while the severity of concomitant injuries was based on the ISS. Correlations between types and severity of maxillofacial injury and types and severity of concomitant injury were conducted to determine the predictability of concomitant injuries based on maxillofacial injury severity. Data were processed using SPSS Statistical software (SPSS, version 20.0 for windows, IBM SPSS Inc, Chicago, IL). Maxillofacial injuries constituted 25.4% of RTC-related admission by the Accident and Emergency Department. A total of 151 (75.1%) patients who presented with concomitant injuries participated in the study. Eighty-one (53.6%) sustained injuries to more than one body region. Head injury was the commonest (99, 65.6%) concomitant injury, followed by orthopedic injury (69, 45.7%). Increasing severity of maxillofacial injury showed a positive correlation with increasing ISS. Also, positive correlation was noted with increasing severity of maxillofacial injury and presence of polytrauma (p = 0.01), traumatic brain injury (p = 0.034), and eye injuries (p = 0.034). There was a high prevalence of maxillofacial injuries in victims of RTC. There was a high incidence of concomitant injuries noted with these maxillofacial injuries. Significantly, this study showed a direct relationship between the severity of maxillofacial injury and head, ocular and polytrauma. This study further emphasizes the need for thorough examination of patients presenting with RTC-related maxillofacial injuries.

To identify the prevalence of depression in Mexican pediatric patients with systemic lupus erythematosus. Analytical transversal study including patients aged 7-16 years with a diagnosis of systemic lupus erythematosus seen at the Pediatric Rheumatology Consultation Service. The disease was classified by means of the MEX-SLEDAI questionnaire. Descriptive statistics with central tendency and dispersion and comparative measurements with chi-squared and Mann-Whitney U tests. Logistic regression and association with odds ratios. SPSS v.21.0 statistical software package. We evaluated 45 patients who presented depression, n=9 (20%), including eight females (89%) and one male (11%), median age 13 years (range, 7-16) in children with depression vs. 13 years (range, 9-14) p=0.941, depression more frequent in schoolchildren. Habitual residence, disease evolution time, and duration of the immunosuppressor did not show a significant difference between both groups. Divorced parents p=0.037. Neuropsychiatric manifestations of lupus presented in 2.2% of all patients and in 100% of patients with depression. Disease activity index (MEX-SLEDAI) did not demonstrate a relationship with the presence of depression. Prevalences in pediatric populations are less that that reported in adults, association with disease activity, evolution time, and immunosuppressor use and duration not found.

The commitment of employees is affected by several factors, including factors related to the organizational climate. The aim of this study was to investigate the relationship between organizational commitment of nurses and the organizational climate in hospital settings. A cross-sectional study was conducted in 2014 at two teaching hospitals in Yazd, Iran. A total of 90 nurses in these hospitals participated. We used stratified random sampling of the nursing population. The required data were gathered using two valid questionnaires: Allen and Meyer's organizational commitment standard questionnaire and Halpin and Croft's Organizational Climate Description Questionnaire. Data analysis was done through SPSS 20 statistical software (IBM Corp., Armonk, NY, USA). We used descriptive statistics and Pearson's correlation coefficient for the data analysis. The findings indicated a positive and significant correlation between organizational commitment and organizational climate (r = 0.269, p = 0.01). There is also a significant positive relationship between avoidance of organizational climate and affective commitment (r = 0.208, p = 0.049) and between focus on production and normative and continuance commitment (r = 0.308, p = 0.003). Improving the organizational climate could be a valuable strategy for improving organizational commitment.

Surrogacy is a popular form of assisted reproductive technology of which only gestational form is approved by most of the religious scholars in Iran. Little evidence exists about the Iranian infertile women's viewpoint regarding gestational surrogacy. To assess the viewpoint of Iranian infertile women toward gestational surrogacy. This descriptive study was conducted at the infertility clinic of Tabriz University of Medical Sciences, Iran. The study sample consisted of 238 infertile women who were selected using the eligible sampling method. Data were collected by using a researcher developed questionnaire that included 25 items based on a five-point Likert scale. Data analysis was conducted by SPSS statistical software using descriptive statistics. Viewpoint of 214 women (89.9%) was positive. 36 (15.1%) women considered gestational surrogacy against their religious beliefs; 170 women (71.4%) did not assume the commissioning couple as owners of the baby; 160 women (67.2%) said that children who were born through surrogacy would better not know about it; and 174 women (73.1%) believed that children born through surrogacy will face mental problems. Iranian infertile women have positive viewpoint regarding the surrogacy. However, to increase the acceptability of surrogacy among infertile women, further efforts are needed.

Faculty members of dental institutions are being asked to assume new academic duties for which they have received no formal training. To succeed in new teaching tasks, faculty development through assessment of teaching skills is essential. A Self-Assessment Questionnaire consisting 18 closed-ended questions was sent to various faculty members of dental colleges of Karnataka. A total of 210 faculty members volunteered to participate in the study. The response rate was 69.8%. Data gathered were statistically analyzed using SPSS software version 16, Chi-square test, and descriptive statistics. In the present study, 27.3% of participants were unaware of andragogy, 33.3% were unaware of teachers development programs, 44.6% do not obtain student feedback after teaching, 52.6% were unaware of peer review of teaching skills, and 50% were unaware of interprofessional education initiatives. By incorporating teaching and learning skills, dental faculty could acquire competencies and academic credentials to become valuable contributors to the institution. This study emphasizes the areas of improvement in dental school learning environment, based on activation of prior knowledge, elaboration of new learning, learning in context, transfer of learning, and organization of knowledge toward learning.

To identify the perception of the nursing professional identity between first and fourth grade students. A descriptive study using a questionnaire. A random sample of 50 and 51 students were selected from the first and fourth grade, respectively. The questionnaire was prepared by expert consensus, and it included a sociodemographic data register, 14 items, and two open questions. Descriptive and bivariate analyses were performed on the data, using the Chi-squared test to determine the possible differences between both grades. SPSS 22.0 statistics software was employed. The open questions were submitted to a content analysis. Statistically significant differences were found between the items related to the diversity of roles that the nursing professionals can develop within the health care system (professional and academic), and between the autonomous nature of their practices. These data were confirmed by the information obtained with the open questions. Academic training is of great importance in the process of acquiring the professional identity of future professionals in nursing, but changing the public image of the profession is the responsibility of all the social agents involved in its development.

Metabolic syndrome is one of the emerging health problems of the world. Its prevalence is high in urban areas. Though pathogenesis is complex, but the interaction of obesity, sedentary lifestyle, dietary, and genetic factors are known as contributing factors. Community-based studies were very few to find out the prevalence or predictors of the syndrome. To ascertain the prevalence and epidemiological predictors of metabolic syndrome. A total of 690 study subjects were chosen by 30 clusters random sampling method from 43 wards of Durgapur city. Data were analyzed in SPSS version 20 software and binary logistic regression was done to find out statistical significance of the predictors. Among 32.75% of the study population was diagnosed as metabolic syndrome according to National Cholesterol Education Program Adult Treatment Panel III definition with a modification for Asia Pacific cut-off of waist circumference. Odds were more among females (2.43), upper social class (14.89), sedentary lifestyle (17.00), and positive family history. The overall prevalence of metabolic syndrome was high in urban areas of Durgapur. Increased age, female gender, higher social status, sedentary lifestyle, positive family history, and higher education were the statistically significant predictors of metabolic syndrome.

Systemic inflammation responses have been associated with cancer development and progression. C-reactive protein (CRP), Glasgow prognostic score (GPS), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), and neutrophil-platelet score (NPS) have been shown to be independent risk factors in various types of malignant tumors. This retrospective analysis of 162 osteosarcoma cases was performed to estimate their predictive value of survival in osteosarcoma. All statistical analyses were performed by SPSS statistical software. Receiver operating characteristic (ROC) analysis was generated to set optimal thresholds; area under the curve (AUC) was used to show the discriminatory abilities of inflammation-based scores; Kaplan-Meier analysis was performed to plot the survival curve; cox regression models were employed to determine the independent prognostic factors. The optimal cut-off points of NLR, PLR, and LMR were 2.57, 123.5 and 4.73, respectively. GPS and NLR had a markedly larger AUC than CRP, PLR and LMR. High levels of CRP, GPS, NLR, PLR, and low level of LMR were significantly associated with adverse prognosis (P < 0.05). Multivariate Cox regression analyses revealed that GPS, NLR, and occurrence of metastasis were top risk factors associated with death of osteosarcoma patients. PMID:28008988

The study of lip-print pattern (cheiloscopy) is a scientific method for personal identification and plays a major role in forensic and criminal investigations. To compare the lip print patterns in Kerala and Maharashtra population and correlate between ABO blood groups. Two hundred subjects, 100 from Maharashtra and 100 from Kerala were considered for the study. Lip prints were recorded, analyzed according to Tsuchihashi classification. The lip print patterns were compared in the two populations, correlated in ABO blood groups. The data obtained was statistically analyzed with SPSS software using chi-square test. In our study, predominant lip print pattern observed in Kerala population was type IV (53%) and Maharashtra population was type II (42%). The difference between the two population was statistically significant (p<0.001). Subjects with A+ and O- blood groups had type II lip print predominance. Subjects with B+, AB+ and O+ blood groups had type IV predominance. The lip print patterns do not show any correlation in ABO blood groups. Lip prints are unique to each individual and are different even in two persons. Lip print patterns were different in the two sub populations studied, and they showed no correlation in ABO blood groups.

The aim of this retrospective study was to compare the peculiarities of maxillofacial injuries caused by interpersonal violence with other etiologic factors. Medical records of 3,724 patients with maxillofacial injuries in São Paulo state (Brazil) were retrospectively analyzed. The data were submitted to statistical analysis (simple descriptive statistics and Chi-squared test) using SPSS 18.0 software. Data of 612 patients with facial injuries caused by violence were analyzed. The majority of the patients were male (81%; n = 496), with a mean age of 31.28 years (standard deviation of 13.33 years). These patients were more affected by mandibular and nose fractures, when compared with all other patients (P < 0.01), although fewer injuries were recorded in other body parts (χ(2) = 17.54; P < 0.01); Victims of interpersonal violence exhibited more injuries when the neurocranium was analyzed in isolation (χ(2) = 6.85; P < 0.01). Facial trauma due to interpersonal violence seem to be related to a higher rate of facial fractures and lacerations when compared to all patients with facial injuries. Prominent areas of the face and neurocranium were more affected by injuries.

Fascin is an actin-bundling protein found in cell membrane protrusions and increases cell motility. The expression of fascin in epithelial neoplasms has been described only recently. No data are available concerning the role of this protein in invasive cholesteatoma. Thus, we investigated the expression of fascin in cholesteatoma tissue and the relationship between fascin expression and intraoperative evaluation of the destruction of the ossicular chain and extent of disease. Cholesteatoma specimens of 28 patients and external auditory canal (EAC) skin specimens of the same patients (as the control group) were collected from mastoidectomies. Immunohistochemical technique was used to investigate the fascin expression in all cholesteatoma tissues and EAC skin specimens. Immunohistochemical staining was assessed semiquantitatively based on the thickness of epithelium. SPSS software version 16.0 (SPSS Inc., Chicago, IL, USA) was performed to statistically analyse the relationships between fascin expression and intraoperative evaluation destruction of ossicular chain and extent of the disease. Immunohistochemically, there was no or very low fascin expression observed in normal epithelial cells of EAC skin, while expressed in cholesteatoma tissue. Also, fascin expression in cholesteatoma tissues was significantly correlated with destruction of ossicular chain and extent of the disease. Fascin expression is usually found in cholesteatoma epithelium and is correlated with destruction of the ossicular chain and extent of disease. Considering all of the correlations between the clinical and histopathological findings, 'fascin immunoexpression scoring' may be used for histological grading of cholesteatoma. © 2015 John Wiley & Sons Ltd.

To observe the effects of extremely low frequency electromagnetic fields (ELF-EMFs) in automotive industry on occupational workers. A total of 704 workers were investigated, and 374 workers were chosen and divided into two groups (control group and exposure group) according to the inclusive criteria, namely male with age 20-40 years old and ≥ 2 years of exposure. The intensities of ELF-EMFs and noise were detected with EFA-300 Field Analyzer (Narda company, Pfullingen, Germany) and AWA5610D integrating sound level meter (Hangzhou Aihua Instruments Co., Ltd, Hangzhou, China), respectively. Survey data were collected by questionnaire, and the physical check-up was done in hospital. All the data were input into SPSS17.0 software (SPSS Inc, Chicago, USA), and the appropriate statistic analyses were carried out. The intensity of EMFs in exposure group was significantly higher than that in control group (p < 0.05), while the noise in two workplaces showed no difference (p>0.05). The survey data collected by questionnaires showed that the symptoms of loss of hair in exposure group were significantly different as compared with that in control group (p < 0.05). The check-up parameters of cardiovascular, liver and hematology system showed significant differences between the two groups (p < 0.05). Survey and check-up data suggest that exposure to ELF-EMFs might have effects on the nervous, cardiovascular, liver, and hematology system of workers.

Intestinal helminths are often associated with poor growth and reduced physical activities, and may worsen already compromised nutritional status of children living in orphanages. To determine the relationship between intestinal helminthiasis and nutritional status of children living in orphanages in Benin City, Nigeria. A cross sectional study carried out from January to April 2011 in orphanages in Benin City, Nigeria. Fresh stool samples from 140 children (0-17 years) living in 10 orphanages in Benin City, were analyzed using the Kato-Katz technique for the detection of ova of helminths between January and April 2011. Physical growth of the children was classified as stunted, wasted, and under-weight using height for age Z-score, weight for height Z-score, and weight for age Z-score below -2 standard deviation of the reference median, respectively, in the World Health Organization growth chart. The data obtained was entered into spread sheet using the Microsoft Excel 2007 and the analysis was done using the Statistical Package for Social Sciences (SPSS) software versions 11.0 and 16.0 (SPSS Inc Chicago, IL, USA). Prevalence of intestinal helminthiasis was 20.7% and was observed highest in children aged 12-17 years. Ascaris lumbricoides and Trichuris trichiura were the intestinal helminths isolated. Nearly all infected subjects had significant stunted growth ( P = 0.014) and another one-quarter were significantly under-weight ( P = 0.021) when compared with noninfected subjects. Intestinal helminthiasis is associated with under-weight and stunted growth.

The aim of this study was to investigate the main factors associated to a diminished health-related quality of life (HRQoL) evaluated by INCAVISA (Health-Related Quality of Life Inventory for Latin American Patients) in patients with rheumatoid arthritis (RA). Female, 18 years or older, RA (American College of Rheumatology 1987 criteria and American College of Rheumatology/European League against Rheumatism 2010 criteria) patients who attended the outpatient rheumatology department of the Hospital Civil "Dr. Juan I. Menchaca," Guadalajara, Mexico, matched with healthy controls were included. Patients with any known comorbidities or treatment with antidepressive drugs were excluded. Trained physicians performed the RA clinical evaluation and INCAVISA. All data were analyzed using SPSS 21.0 software (SPSS Inc, Chicago, IL); P < 0.05 was considered statistically significant. Patients with polypharmacy (≥3 drugs) had a lower HRQoL by INCAVISA. The number of drugs, total comorbidities, and DAS-28 (Disease Activity Score on 28 Joints) were negatively correlated with total INCAVISA. In multivariate analysis, DAS-28 and polypharmacy were independent predictors for a negative perception of HRQoL evaluated by INCAVISA in RA patients. Disease activity and disability secondary to RA have a negative impact in the HRQoL. Other factors such as the number of drugs prescribed to these patients have been shown to be important for the negative perception of their HRQoL evaluated by INCAVISA.

Introduction: Three-dimensional (3D) scanners are widely used in medicine. One of the applications of 3D scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. The aim of this study was to evaluate the precision and accuracy of a modified 3D scanner fabricated in this study. Methods: In this work, a 3D scan of the human body was obtained using DAVID Laser Scanner software and its calibration background, a linear low-power laser, and one advanced webcam. After the 3D scans were imported to the Geomagic software, 10 anthropometric dimensions of 10 subjects were obtained. The measurements of the 3D scanner were compared to the measurements of the same dimensions by a direct anthropometric method. The precision and accuracy of the measurements of the 3D scanner were then evaluated. The obtained data were analyzed using an independent sample t test with the SPSS software. Results: The minimum and maximum measurement differences from three consecutive scans by the 3D scanner were 0.03 mm and 18 mm, respectively. The differences between the measurements by the direct anthropometry method and the 3D scanner were not statistically significant. Therefore, the accuracy of the 3D scanner is acceptable. Conclusion: Future studies will need to focus on the improvement of the scanning speed and the quality of the scanned image.

Background: Traditional teaching methods used in medical education cannot wholly respond to the rapid changes and growth of information as well as continuous changes in the educational needs of society, especially patients with chronic diseases such as multiple sclerosis (MS). Therefore, this study was designed with the aim of examining the effect of electronic package on satisfaction in MS patients. Materials and Methods: The research was a quasi-experimental study. It was carried out at the MS Kashani Center affiliated to the Isfahan University of Medical Sciences, in 2013. One hundred twenty-eight patients with MS were allocated randomly into two equal groups of 64 each for education by booklet (control) and education by multimedia software (experimental) for 2 weeks. Data were collected by processing questionnaires, which consisted of questions about satisfaction (17 items) and questions about demographic and disease characteristics (9 items), answered by both groups before and 2 weeks after education. SPSS version 14 (DARYA software, Iran) was used to conduct statistical tests such as the independent t-test and the paired t-test for analyzing the data. The statistical significance level was less than 0.05. Results: The results show that there was not any significant difference between the satisfaction scores of the electronic package and control groups before intervention, but that there was a significant difference after 2 weeks’ intervention (P = 0.010). Conclusion: The electronic programs comprised an attractive education method. So this technology can increase motivation in MS patients to study more about the disease process. PMID:27308261

Autonomic dysfunction with dominant sympathetic tone is a common finding among hypertensives and prehypertensives. Uric acid is one of the independent predictors of hypertension. There are very few studies which have shown a relationship between the autonomic tone and uric acid generation pathway among prehypertensives and hypertensives. Aim of the study was to estimate and correlate serum uric acid levels with autonomic function as measured by heart rate variability (HRV) among prehypertensives and hypertensives. Cross-sectional study of three groups, prehypertensives, hypertensives and normotensives, classified according to Joint National Committee VII criteria, with 35 subjects in each group were included in this study. Serum uric acid levels were estimated by using colorimetric assay kit. HRV was analyzed after recording lead II Electrocardiogram using RMS Vagus HRV software (RMS, India). One-way ANOVA and Pearson's correlation was done using SPSS 18.0 software. Mean uric acid levels were 5.62±2.21mg/dL in normal subjects, 7.06±2.87mg/dL in prehypertensives and 9.77±2.04mg/dL in hypertensives. There was statistically significant negative correlation between uric acid and time domain parameters of HRV in the whole sample and among prehypertensives and positive correlation with low frequency power (LF) in ms(2) and n.u. Serum uric acid levels were high in prehypertensives and hypertensives as compared to normal subjects. Further, there was statistically significant correlation seen between uric acid levels and sympathetic domain parameters particularly among prehypertensives. Copyright © 2015 SEHLELHA.

This cross-sectional study was conducted to explore the specialty chosen by the dental students for postgraduate studies and the future aspirations of students in a Saudi Arabia dental college. Of the total number of 120 questionnaires that were distributed, 107 subjects responded with selective responses and a response rate of 89%. A descriptive survey was conducted using one of the questionnaires among the students of dentistry at the dental college, Prince Sattam Bin Abdulaziz University, Al-Kharj among male students (men's college) for a period of 2 months. The data were analyzed using the statistical software program, predictive analytics software Statistics version 22.0 (SPSS Inc., Chicago, IL, USA). A hundred and seven of the 120 students took part in the study. A passion for orthodontics (42.9%) was reported to be the most important factor that influenced the decision to pursue specialty training in orthodontics followed by intellectual stimulation/challenge (25%). The decision to pursue orthodontics was made by 32.1% of the respondents while in dental school; 35.7% took the decision after completing dental school during private practice and 14.3% during a dental residency, whereas 3.6% had already decided before initiating their dental school studies. Working in a private practice environment was preferred by 11 residents (39.3%). Only four residents indicated that they would most likely be practicing in an academic setting while 10 were undecided. The zest for nonclinical specialties is less among students at Prince Sattam Bin Abdulaziz University's dental college, Saudi Arabia.

2013-09-15

An analytical method for quantifying underivatized amino acids (AAs) in urine samples of rats was developed by using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Classification of type 2 diabetes rats was based on urine amino acids metabolic profiling. LC-MS/MS analysis was applied through chromatographic separation and multiple reactions monitoring (MRM) transitions of MS/MS. Multivariate profile-wide predictive models were constructed using partial least squares discriminant analysis (PLS-DA) by SIMAC-P 11.5 version software package and hierarchical cluster analysis (HCA) by SPSS 18.0 version software. Some amino acids in urine of rats have significant change. The results of the present study prove that this method could perform the quantification of free AAs in urine of rats by using LC-MS/MS. In summary, the PLS-DA and HCA statistical analysis in our research were preferable to differentiate healthy rats and type 2 diabetes rats by the quantification of AAs in their urine samples. In addition, comparing with health group the seven increased amino acids in urine of type 2 rats were returned to normal under the treatment of acarbose. Copyright © 2013 Elsevier B.V.

Vocal abuse and misuse would result in vocal fold polyp. Certain features define the extent of vocal folds polyp effects on voice acoustic parameters. The present study aimed to define the effects of polyp size on acoustic voice parameters, and compare these parameters in hemorrhagic and non-hemorrhagic polyps. In the present retrospective study, 28 individuals with hemorrhagic or non-hemorrhagic polyps of the true vocal folds were recruited to investigate acoustic voice parameters of vowel/ æ/ computed by the Praat software. The data were analyzed using the SPSS software, version 17.0. According to the type and size of polyps, mean acoustic differences and correlations were analyzed by the statistical t test and Pearson correlation test, respectively; with significance level below 0.05. The results indicated that jitter and the harmonics-to-noise ratio had a significant positive and negative correlation with the polyp size (P=0.01), respectively. In addition, both mentioned parameters were significantly different between the two types of the investigated polyps. Both the type and size of polyps have effects on acoustic voice characteristics. In the present study, a novel method to measure polyp size was introduced. Further confirmation of this method as a tool to compare polyp sizes requires additional investigations.

Background Glioblastoma (GBM) is a highly invasive, aggressive, and incurable brain tumor. Genetic factors play important roles in GBM risk. The aim of this study was to elucidate the influence of gene polymorphism on GBM susceptibility. Material/Methods In this case-control study, we included 72 GBM patients and 320 healthy controls to analyze the association between 29 single-nucleotide polymorphisms and GBM cancer risk in the Chinese Han population. The single-nucleotide polymorphisms were determined by Sequenom MassARRAY RS1000 and statistical analysis was performed using SPSS software and SNPStats software. Results Using the χ2 test, we found that rs2297440 and rs6010620 in RTEL1 increased risk of GBM. In the recessive model, we also found that the genotypes “CC” of rs2297440 and “GG” of rs6010620 in RTEL1 significantly increased GBM risk. The variant TT genotype of TREH rs17748 and the variant TT genotype of PHLDB1 rs498872 decreased GBM risk in the recessive model. We also found that the TREH rs17748 variant C allele showed an increased risk in males in the dominant model. Conclusions Our results suggest a significant association between the RETL1, TREH, and PHLDB1 genes and GBM development in the Han Chinese population. PMID:26156397

The purpose of this in vitro study was to evaluate the generated temperature of the Er:YAG laser, with three different pulse durations for apicectomy, compared with tungsten bur and surgical saw. Apicectomy is an endodontic surgery performed to remove the root apex and curette adjacent periapical tissue because of lesions of the apical area that are not healing properly. Sixty single-rooted extracted human teeth were resected by three cutting methods: tungsten bur, surgical saw, and Er:YAG laser irradiation with three different pulse durations; pulse duration 50 μs, pulse duration 100 μs, and pulse duration 300 μs. Teflon-insulated, type K thermocouples were used to measure temperature changes during the apicectomy process. Data were analyzed using the general linear models procedure of the SPSS statistical software program. Although there was no statistically significant difference for the mean values of temperature changes at 1 mm away to the cutting site of teeth, there was statistically significant difference among groups for the mean values of temperature changes at 3 mm away to the cutting site of teeth. Additionally, there was statistically significant difference among groups for the total time required for apicectomy. The laser irradiation with pulse duration 50 μs appears to have the lowest temperature rise and the shortest time required for apicectomy of the three pulse durations. However, Er:YAG laser for apicectomy in all pulse durations could be used safely for resection in endodontics in the presence of sufficient water.

BACKGROUND The aim of this study was to investigate the outcomes and stent implantation timing of portal vein stenosis intervention after pediatric liver transplantation (pLT). MATERIAL AND METHODS The clinical data of 30 children with post-liver transplantation portal vein stenosis/occlusion (PVS/O) between Jan 2008 and Jun 2015 were retrospectively analyzed. The successfully re-opened cases used balloon angioplasty or stent implantation. SPSS13.0 software was used for statistical analysis and paired t test of the pressure gradient at both ends of the stenosis, diameter and flow rate within the stenosis, platelet count, and albumin in the PVS children before and after balloon angioplasty, with p<0.05 considered as statistically significant. Among the 30 patients, 6 received a stent implant in their first treatment, 22 received balloon angioplasty in their first treatment, and in 2 the re-opening could not be achieved. RESULTS The diameter of the stenotic segment, portal vein velocity, pressure gradient at both ends of the stenosis, and platelet count in these children with portal vein stenosis/occlusion (PVS/O) showed statistically significant differences when comparing values before and after intervention (p<0.05), but albumin showed no statistically significant difference (p>0.05). CONCLUSIONS Intervention therapy for portal vein stenosis after pediatric liver transplantation (pLT-PVS) is a safe and effective treatment, and patients with portal vein torsion, intimal tearing, or long portal vein segment occlusion should undergo stent implantation.

The massive surge in the production of microarray data poses a great challenge for proper analysis and interpretation. In recent years numerous computational tools have been developed to extract meaningful interpretation of microarray gene expression data. However, a convenient tool for two-groups comparison of microarray data is still lacking and users have to rely on commercial statistical packages that might be costly and require special skills, in addition to extra time and effort for transferring data from one platform to other. Various statistical methods, including the t-test, analysis of variance, Pearson test and Mann-Whitney U test, have been reported for comparing microarray data, whereas the utilization of the Wilcoxon signed-rank test, which is an appropriate test for two-groups comparison of gene expression data, has largely been neglected in microarray studies. The aim of this investigation was to build an integrated tool, ArraySolver, for colour-coded graphical display and comparison of gene expression data using the Wilcoxon signed-rank test. The results of software validation showed similar outputs with ArraySolver and SPSS for large datasets. Whereas the former program appeared to be more accurate for 25 or fewer pairs (n < or = 25), suggesting its potential application in analysing molecular signatures that usually contain small numbers of genes. The main advantages of ArraySolver are easy data selection, convenient report format, accurate statistics and the familiar Excel platform.

The current study aimed to explore the public views and expectation about a successful communication process between the healthcare providers/physicians and patients in Penang Island, Malaysia. A cross-sectional study was conducted in Penang Island using a 14-item questionnaire. Statistical Package for Social Sciences (SPSS) software version 15.0® were used to analyze the collected data. A nonparametric statistics was applied; the Chi-square test was applied to measure the association among the variables. P-values less than 0.05 were considered statistically significant. A total of N (500) respondents have shown willingness to participate in the study with a response rate of 83.3%. The majority 319 (63.9%) have disclosed to communicate with their healthcare providers in the Malay language and about 401 (80.4%) of the respondents were found satisfied with the information provided by the physician. It was a common expectation by the most of the sample to focus more on the patient history before prescribing any medicine. Moreover, about 60.0% of the respondents expected that the healthcare providers must show patience to the patient's queries. The level of satisfaction with the information shared by the healthcare providers was higher among the respondents with a higher education level. Furthermore, patients with higher level of education expect that physician shouldwell understand their views and medical history to prescribe a better therapeutic regimen. PMID:23112539

A total of 196 patients, admitted to the clinic in the first trimester and with ongoing pregnancy follow-up of between May 2012 and January 2013, were included in the study. Toxoplasma IgG and IgM antibodies were detected by ELISA test in blood samples obtained from patients during routine screening. SPSS statistical software, version 19.0 was used to analyze the data. Descriptive statistics were used to present the data, percentage, mean, and standard deviation. Chi-square test was used for categorical variables. p-value for statistical significance was defined as p<0.05. The mean age was 29.07±5.3 years in our study group. Anti-Toxoplasma IgG and IgM antibodies were found in 28.8% and 2.7%, respectively; 58.9% of pregnant women in the study reported that they had done at least one risky behavior during their pregnancy. However, there was no significant association between T. gondii IgG antibody positivity and risk factors, such as pregnancy, feeding animals in the past years, and consumption of raw food products (p>0.05). We found that Toxoplasma IgG antibody seropositivity (28.8%) was similar to that found in the other studies from western Turkey.

Background: Patient safety culture plays an important role in healthcare systems, especially in chemotherapy and oncology departments (CODs), and its assessment can help to improve quality of services and hospital care. Objective: This study aimed to evaluate and compare items and dimensions of patient safety culture in the CODs of selected teaching hospitals of Iran and Tehran University of Medical Sciences. Materials and Methods: This descriptive-analytical cross-sectional survey was conducted during a six-month period on 270 people from chemotherapy and oncology departments selected through a cluster sampling method. All participants answered the standard questionnaire for “Hospital Survey of Patient Safety Culture” (HSOPSC). Statistical analyses were performed using SPSS/18 software. Results: The average score for patient safety culture was three for the majority of the studied CODs. Statistically significant differences were observed for supervisor actions, teamwork within various units, feedback and communications about errors, and the level of hospital management support. (p<0.05). Relationships between studied hospitals and patient safety culture were not statistically significant (p>0.05). Conclusion: Our results showed that the overall status of patient safety culture is not good in the studied CODs. In particular, teamwork across different units and organizational learning with continuous improvement were the only two properly operating items among 12 dimensions of patient safety culture. Therefore, systematic interventions are strongly required to promote communication. PMID:29072411

The purpose of this study was to examine the fracture strength and surface microhardness of computer-aided design/computer-aided manufacturing (CAD/CAM) materials in vitro. Mesial-occlusal-distal inlays were made from five different CAD/CAM materials (feldspathic ceramic, CEREC blocs; leucite-reinforced ceramic, IPS Empress CAD; resin nano ceramic, 3M ESPE Lava Ultimate; hybrid ceramic, VITA Enamic; and lithium disilicate ceramic, IPS e.max CAD) using CEREC 4 CAD/CAM system. Samples were adhesively cemented to metal analogs with a resin cement (3M ESPE, U200). The fracture tests were carried out with a universal testing machine. Furthermore, five samples were prepared from each CAD/CAM material for micro-Vickers hardness test. Data were analyzed with statistics software SPSS 20 (IBM Corp., New York, USA). Fracture strength of lithium disilicate inlays (3949 N) was found to be higher than other ceramic inlays (P < 0.05). There was no difference between other inlays statistically (P > 0.05). The highest micro-Vickers hardness was measured in lithium disilicate samples, and the lowest was in resin nano ceramic samples. Fracture strength results demonstrate that inlays can withstand the forces in the mouth. Statistical results showed that fracture strength and micro-Vickers hardness of feldspathic ceramic, leucite-reinforced ceramic, and lithium disilicate ceramic materials had a positive correlation.

Time management skills are essential for nursing students' success, and development of clinical competence. The purpose of this study was to determine the relationship between time management skills and anxiety and academic motivation of nursing students in Tehran medical sciences universities in 2015. This cross-sectional study was carried out on 441 nursing students in three medical universities in Tehran. Random stratified sampling was done to select the samples. Data were collected using demographic Questionnaire, Time Management Questionnaire (TMQ), Spielberger State-Trait Anxiety Inventory (STAI) and Academic Motivation Scale (AMS), which was completed t by self-report. Data were analyzed using SPSS 18 software with descriptive and analytical statistics such as ANOVA, independent t-test, Regression and Pearson Correlation Coefficient. Most participants had a moderate level of time Management skills (49%), State Anxiety (58%), Trait Anxiety (60%) and Academic Motivation (58%). The results also showed a statistically significant negative correlation between the students' TMQ scores and the state anxiety (r= -0.282, p< 0.001) and trait anxiety scores (r= -0.325, p<0.001). Moreover, there was a statistically significant positive correlation between the students' TMQ scores and AMS scores (r= 0.279, p< 0.001). Regarding the findings, it seems that it is necessary to plan for improving time management skills in order to enhance academic motivation and reduce anxiety rates among nursing students.

The prevalence of infertility among the Uygur and Kazak women were 26.5% and 21.7% respectively, the difference was not statistically significant (P>0.05). The prevalence of primary infertility among the Uygur and Kazak women were 14.7%, and 8.7%, respectively, the difference was statistically significant (P<0.05). The prevalence of secondary infertility among the Uygur and Kazak women were 11.8% and 13.0%, respectively, the difference was not statistically significant (P>0.05). The prevalence of infertility in the Uygur women was correlated with household income, pelvic inflammation, endometriosis and BMI, while the prevalence of infertility in the Kazak women was correlated with age of marriage, endometriosis and the history of ectopic pregnancy. The prevalence of infertility was high among the Uygur and Kazak women at reproductive age in Xinjiang. The influencing factors varied with ethnic group. It is necessary to conduct targeted health education and provide early diagnosis and effective treatment.

To explore the relationship between the external validity and the internal validity of hypertension RCTs conducted in China. Comprehensive literature searches were performed in Medline, Embase, Cochrane Central Register of Controlled Trials (CCTR), CBMdisc (Chinese biomedical literature database), CNKI (China National Knowledge Infrastructure/China Academic Journals Full-text Database) and VIP (Chinese scientific journals database) as well as advanced search strategies were used to locate hypertension RCTs. The risk of bias in RCTs was assessed by a modified scale, Jadad scale respectively, and then studies with 3 or more grading scores were included for the purpose of evaluating of external validity. A data extract form including 4 domains and 25 items was used to explore relationship of the external validity and the internal validity. Statistic analyses were performed by using SPSS software, version 21.0 (SPSS, Chicago, IL). 226 hypertension RCTs were included for final analysis. RCTs conducted in university affiliated hospitals (P < 0.001) or secondary/tertiary hospitals (P < 0.001) were scored at higher internal validity. Multi-center studies (median = 4.0, IQR = 2.0) were scored higher internal validity score than single-center studies (median = 3.0, IQR = 1.0) (P < 0.001). Funding-supported trials had better methodological quality (P < 0.001). In addition, the reporting of inclusion criteria also leads to better internal validity (P = 0.004). Multivariate regression indicated sample size, industry-funding, quality of life (QOL) taken as measure and the university affiliated hospital as trial setting had statistical significance (P < 0.001, P < 0.001, P = 0.001, P = 0.006 respectively). Several components relate to the external validity of RCTs do associate with the internal validity, that do not stand in an easy relationship to each other. Regarding the poor reporting, other possible links between two variables need to trace in the future methodological researches.

One of the most specific and critical regulators of angiogenesis is vascular endothelial growth factor (VEGF), which regulates endothelial proliferation, permeability, and survival. Vascular endothelial growth factor is an angiogenic mediator in tumors and has been implicated in the pathogenesis and progression of cancer. Adipose tissue is a major endocrine and it secretes hormones termed adipokines. These factors are derived from adipocytes and include proteins and metabolites such as adiponectin. Recently, adiponectin was also shown to modulate angiogenesis. This study was designed to determine the serum VEGF and adiponectin levels in patients with benign and malignant gynecological diseases and if there was a correlation between serum VEGF and adiponectin. Serum samples, collected fasting before surgery or intervention, were available for total of 114 female patients recorded between October 2006 and December 2008. Diagnosis of benign and malignant gynaecological diseases was established by biopsy. Serum levels VEGF and adiponectin were using commercially available enzyme linked immunosorbent assay (R&D Systems Inc, Minneapolis, MN), respectively. Statistical analysis was performed by using the SPSS 9.0 software package (SPSS, Inc, Chicago, IL). The correlation between serum VEGF and serum Adiponectin was calculated using the Pearson correlation coefficient. P values of < 0.05 were considered statistically significant. Our results were analyzed on the basis of 2 different parameters: age and benign and malignant gynecological diseases of the patient. Only for serum VEGF levels was a significant difference observed (P = 0.004) between patients with benign and malignant gynecological diseases. A significantly inverse correlation between serum VEGF and adiponectin levels among patients with benign and malignant gynecological diseases was found. Adiponectin level is not correlated with body mass index. This is one of the first report on adiponectin in benign and malignant gynecological diseases. Future studies are needed to address the clinical potential role of adiponectin in cancer.

Nocturnal enuresis, often called bedwetting or sleep wetting, is a common problem in children after the age of five and may lead to symptoms such as infection, incontinence and frequent urination. This problem refers to a state in which children after the age of five have no control of their urine for six continuous months and it cannot be attributed to any organic factors or drug use. In this study we aimed to study generalized anxiety disorder as one of the possible causes of primary nocturnal enuresis. In this case-control study 180 children with primary nocturnal enuresis and same number of healthy children with a mean age of 7 - 17 years old with the same demographic characteristics were selected. The study took place at Amir Kabir hospital of Arak, Iran during year 2014. After collecting the information, diagnosis was verified based on the diagnostic and statistical manual of mental disorders (DSM) IV-TR criteria. Results were analyzed using the SPSS software (IBM Corp. Released 2011. IBM SPSS Statistics for Windows, version 20.0. Armonk, NY: IBM Corp.). Frequency of generalized anxiety disorder, panic disorder, school phobia, social anxiety, separation anxiety, history of anxiety in mother, history of primary nocturnal enuresis in parent's family and body mass index had a significant difference between the two groups (P = 0.005). With the results obtained from this study we could say that there was a clear significant difference between the two control and patient groups for all subgroups of anxiety disorders such as generalized anxiety disorder and their relationship with primary nocturnal enuresis. Given the higher prevalence of generalized anxiety disorder, panic disorder, school phobia, social anxiety, separation anxiety and comparison with healthy children, it is recommended for all children with primary nocturnal enuresis to be investigated and treated for generalized anxiety disorder.

Junior doctors are reported to make most of the prescribing errors in the hospital setting. The aim of the following study is to determine the knowledge intern doctors have about prescribing errors and circumstances contributing to making them. A structured questionnaire was distributed to intern doctors in National Hospital Abuja Nigeria. Respondents gave information about their experience with prescribing medicines, the extent to which they agreed with the definition of a clinically meaningful prescribing error and events that constituted such. Their experience with prescribing certain categories of medicines was also sought. Data was analyzed with Statistical Package for the Social Sciences (SPSS) software version 17 (SPSS Inc Chicago, Ill, USA). Chi-squared analysis contrasted differences in proportions; P < 0.05 was considered to be statistically significant. The response rate was 90.9% and 27 (90%) had <1 year of prescribing experience. 17 (56.7%) respondents totally agreed with the definition of a clinically meaningful prescribing error. Most common reasons for prescribing mistakes were a failure to check prescriptions with a reference source (14, 25.5%) and failure to check for adverse drug interactions (14, 25.5%). Omitting some essential information such as duration of therapy (13, 20%), patient age (14, 21.5%) and dosage errors (14, 21.5%) were the most common types of prescribing errors made. Respondents considered workload (23, 76.7%), multitasking (19, 63.3%), rushing (18, 60.0%) and tiredness/stress (16, 53.3%) as important factors contributing to prescribing errors. Interns were least confident prescribing antibiotics (12, 25.5%), opioid analgesics (12, 25.5%) cytotoxics (10, 21.3%) and antipsychotics (9, 19.1%) unsupervised. Respondents seemed to have a low awareness of making prescribing errors. Principles of rational prescribing and events that constitute prescribing errors should be taught in the practice setting.

Breast cancer is a life-threatening condition affecting women around the world. The early detection of breast lumps using a breast self-examination (BSE) is important for the prevention and control of this disease. The aim of this study was to examine BSE behavior and its predictive factors among female university students using the Health Belief Model (HBM). This investigation was a cross-sectional survey carried out with 334 female students at Urmia University of Medical Sciences in the northwest of Iran. To collect the necessary data, researchers applied a valid and reliable three-part questionnaire. The data were analyzed using descriptive statistics and a chi-square test, in addition to multivariate logistic regression statistics in SPSS software version 16.0 (SPSS Inc., Chicago, IL, USA). The results indicated that 82 of the 334 participants (24.6%) reported practicing BSEs. Multivariate logistic regression analyses showed that high perceived severity [OR = 2.38, 95% CI = (1.02-5.54)], high perceived benefits [OR = 1.94, 95% CI = (1.09-3.46)], and high perceived self-efficacy [OR = 13.15, 95% CI = (3.64-47.51)] were better predictors of BSE behavior (P < 0.05) than low perceived severity, benefits, and self-efficacy. The findings also showed that a high level of knowledge compared to a low level of knowledge [OR = 5.51, 95% CI = (1.79-16.86)] and academic undergraduate and graduate degrees compared to doctoral degrees [OR = 2.90, 95% CI = (1.42-5.92)] of the participants were predictors of BSE performance (P < 0.05). The study revealed that the HBM constructs are able to predict BSE behavior. Among these constructs, self-efficacy was the most important predictor of the behavior. Interventions based on the constructs of perceived self-efficacy, benefits, and severity are recommended for increasing women's regular screening for breast cancer.

Pradhan, Raunak; Kulkarni, Deepak

2017-01-01

Introduction Fear of dental pain is one of the most common reasons for delaying dental treatment. Local Anaesthesia (LA) is the most commonly employed technique of achieving pain control in dentistry. Pterygomandibular Nerve Block (PNB), for achieving mandibular anaesthesia has been the traditional technique used and is associated with a few set of complications which include pain, nerve injury, trismus, and rarely facial nerve palsy, and sustained soft tissue anaesthesia. These complications have resulted in a rapid need for research on alternative local anaesthetic techniques. Aim This study was undertaken with the objective to determine pain, duration, profoundness and complications associated with administration of Intraligamentary Injection Technique (ILT). Materials and Methods This study was conducted on 194 patients (male=122, female=72) who reported for dental extractions in mandibular posteriors. The ILT was administered with ligajet intraligamentary jet injector using cartridge containing lignocaine hydrochloride 2% with adrenaline 1:80000 and a 30 gauge needle at buccal (mesiobuccal), lingual, mesial and distal aspect of the mandibular molars. The data was analyzed by using statistical computer software SPSS 11.0 (Statistical package for social sciences 11.O version of SPSS Inc.). Median was derived for Pain on Injection (PI) and Pain during Procedure (PP). Mean and standard deviation was derived for Duration of Anaesthesia (DA). Results Various advantages were seen such as, localized soft tissue anaesthesia, decreased PI (SD=0.83), and minimal PP (SD=0.94). The DA (SD=4.62) and mean value of 24.06 minutes. Conclusion This study is one of its kinds where intraligamentary injection has been used for extraction of mandibular molars. It was also successfully used in patients with exaggerated gag reflex and patients suffering from trismus due to oral submucous fibrosis. The intraligamentary injection technique can thus be used effectively to anaesthetize mandibular molars, as a primary technique for extraction of mandibular posterior teeth. PMID:28274058

Introduction Prevalence of ameloblastomas has been established worldwide but collective data of ameloblastoma in Southeast Asian countries has not been well analyzed. Aim Aim of this study was to report analysis and comparison of the prevalence and demographic data of clinical features of ameloblastoma and its histopathological variants in Southeast Myanmar and lower Northern Thailand populations. Materials and Methods A retrospective study on ameloblastoma was performed based on the availability of oral biopsy specimens in Faculty of Dentistry, Naresuan University, Phitsanulok, Thailand, between January 2002 and August 2015. The collected data were subjected to descriptive statistical analyses with the SPSS version 17.0 statistical software package (SPSS Inc., Chicago, USA). Pearson’s chi square (χ2) test and t-test were employed. The critical level of significance was set at p<0.05. Results Total of 616 cases were reviewed, 30 cases (5%) were diagnosed as ameloblastoma with male:female ratio of 1.14:1. The mean age of the patients was 31.3±15.6 years. The predominance anatomical distribution was observed in the mandible (86.7%). Posterior body-ramus-angle region was the most common site. Almost all cases were asyptomatic and most common clinical manifestation was swelling of affected region. Multilocular radiolucency was observed in 70% of cases, whereas 30% were unilocular. Three subtypes of ameloblastomas were diagnosed: unicystic ameloblastoma (20%), conventional solid/multicystic ameloblastoma (70%), and desmoplastic ameloblastoma (10%). The most common histologic pattern was the plexiform type (57.2%) followed by follicular type (23.8%). Conclusion Prevalence of ameloblastoma in Southeast Myanmar and lower Northern Thailand populations correspond with data from other geographic areas of Thailand and other Asian countries. However, some demographic and histopathological profiles are different, with plexiform ameloblastoma being the most common subtype in this study. PMID:28274056

The burden of noncommunicable diseases (NCDs) and certain behavioral risk factors related to NCDs (unhealthy behaviors) are becoming more common. This survey aims to map out such common unhealthy behaviors among all men 35 to 50 years old in a Medical Officer of Health area in the Western Province of Sri Lanka using a geographical information system (GIS) and an interviewer administered questionnaire by visiting all households in the study area. Data were analyzed with ARC GIS and SPSS software. Geographical areas where men with unhealthy behaviors cluster together (clusters) were identified and visually and statistically related to locations of schools, places of religious worship, and factories in the area. It was revealed that clusters of unhealthy behaviors are mostly seen in areas with less population density. Smoking and alcohol are clustering in estate areas occupied by Tamils. This way GIS mapping could be used to identify and reduce the burden of NCDs by visualizing clusters and how certain locations affect their spread. PMID:26489433

To investigate the influence of IL-35 in the pathogenesis of periodontitis and oral lichen planus, and the correlation between periodontitis and oral lichen planus patients. The gingival crevicular fluid（GCF） and serum were collected from patients with oral lichen planus (n=20), periodontitis (n=20), periodontitis and oral lichen planus (n=20) and healthy controls (n=12). The patients' basic information, probing depth, clinical attachment loss, gingival index, sulcus bleeding index were measured and collected. The expression of IL-35 in GCF and serum was detected by ELISA. SPSS19.0 software package was used for statistical analysis. The concentration of IL-35 in patients with periodontitis and oral lichen planus was significantly higher than that of other groups(P<0.05). There was significantly positive correlation between IL-35 level and periodontal clinical parameters. Periodontitis and oral lichen planus may increase the concentration of IL-35 both in serum and GCF. The expression of IL-35 was positively correlated with periodontitis and oral lichen planus.

Stress at clinical environment is one of the cases that could affect the education quality among nursing students. The study aims to investigate Iranian nursing students' perceptions on the stressors in clinical environment in the South Western part of Iran. A cross-sectional descriptive study was conducted in 2010 to include 300 nursing students after their completion of second clinical nursing course in a hospital environment. Data were collected using a researcher-made questionnaire, with focus on the clinical environment stressors from personal, educational and training viewpoints. Data analysis was performed using SPSS software (IBM Corporation, Armonk, NY, USA) and descriptive statistics tests. Among the various stressors, the highest scores were given to the faculty (71 ± 19.77), followed by the students' personal characteristics (43.15 ± 21.79). Given that faculty-related factors provoked more stress in nursing students, nursing administration should diligently evaluate and improve communication skills among faculty to reduce student stress and enhance learning. © 2014 Wiley Publishing Asia Pty Ltd.

To study the influence of different opaque thickness on the bond strength of porcelain-fused-to metal (PFM) restorations. The testing sheets were made as the samples of ISO9693. With different sintering temperature and different opaque thickness on the bond strength of PFM restorations, the primary pressure of porcelain crack was measured by using three-points-bending test. Statistical analysis was carried out using a SPSS 10.0 software package. A post hoc multiple comparison test (Student-Newman-Keuls) was performed to evaluate the differences between the individual groups. In low sintering temperature group, the thin layer of opaque significantly improved the bond strength compared with thick layer of opaque (P<0.05). In high sintering temperature group, the thickness of opaque has no significant influence on the PFM bonding strength. Using the opaque, the bonding strength was better than those without opaque. The thickness of opaque has a little influence on the PFM bonding strength.

We applied confocal Raman spectroscopy to investigate 12 normal bladder tissues and 30 tumor tissues, and then depicted the spectral differences between the normal and the tumor tissues and the potential canceration mechanism with the aid of the high-performance liquid chromatographic (HPLC) technique. Normal tissues were demonstrated to contain higher tryptophan, cholesterol and lipid content, while bladder tumor tissues were rich in nucleic acids, collagen and carotenoids. In particular, β-carotene, one of the major types of carotenoids, was found through HPLC analysis of the extract of bladder tissues. The statistical software SPSS was applied to classify the spectra of the two types of tissues according to their differences. The sensitivity and specificity of 96.7 and 66.7% were obtained, respectively. In addition, different layers of the bladder wall including mucosa (lumps), muscle and adipose bladder tissue were analyzed by Raman mapping technique in response to previous Raman studies of bladder tissues. All of these will play an important role as a directive tool for the future diagnosis of bladder cancer in vivo.

This study aims to understand the relationship between participating nurses' motivation, achievement and satisfaction before and after they learned to program in Excel Visual Basic for Applications (Excel VBA). We held a workshop to train nurses in developing simple Excel VBA information systems to support their clinical or administrative practices. Before and after the workshop, the participants were evaluated on their knowledge of Excel VBA, and a questionnaire was given to survey their learning motivation and satisfaction. Statistics softwares Winsteps and SPSS were used for data analysis. Results show that the participants are more knowledgeable about VBA as well as more motivated in learning VBA after the workshop. Participants were highly satisfied with the overall arrangement of the workshop and instructors, but didn't have enough confidence in promoting the application of Excel VBA themselves. In addition, we were unable to predict the participants' achievement by their demographic characteristics or pre-test motivation level.

The aim of the study is to estimate the prevalence of suicidal ideation among Moroccan consultants in primary health care system. We conducted a cross sectional survey in three health care centers in two cities of Morocco to estimate the prevalence of suicidal ideation, plan and suicide attempts among 396 consultants in the primary health care system, using the Mini International neuropsychiatric interview. Patients were 18 years and older, without known psychiatric or chronic somatic disease. Statistical analysis was performed by the SPSS 13.0 software. The prevalence of suicidal ideation was 5.3%, and 2.7% of the patients planned their suicide and 1.2% tried to commit suicide. The multivariate analysis did not demonstrate significant association. Suicidal ideation, plan and suicide attempts are prevalent in primary health care patients, but they are still under diagnosed. An adequate training of physicians and the establishment of education programs is essential to reduce the rate of suicide.

This study compared the immunohistochemical expression of ki-67, transforming growth factor beta 1 (TGF-β1) and intercellular adhesion molecule-1 (ICAM-1) in inflammatory periapical cysts and residual cysts. The study sample was composed by 25 periapical cysts and 25 residual cysts and immunohistochemical reactions were carried out using antibodies directed against ICAM-1, TGF-β1 and ki-67. Clinical, radiological, gross, histological and immunohistochemical data were tabulated for descriptive and comparative analysis using the SPSS software and differences were considered statistically significant when p<0.05%. There were no differences between the expression of ICAM-1 (p=0.239) and TGF-β1 (p=0.258) when comparing both groups. Ki-67 labeling index was higher in residual cysts compared to periapical cysts (p=0.017). Results from the present study suggest that some specific inflammatory stimuli on residual cysts would modulate their mechanisms of etiopathogenesis, growing and repair.

This study explores the attitudes of Finnish nurse entrepreneurs to management, their adoption of the manager's role, managerial assertiveness, development and training needs in management and associated factors. The research was conducted as part of a questionnaire survey among 335 entrepreneurs with different educational backgrounds. The sample for the study reported here consisted of those respondents who had a registered nurse degree. The data were analysed using SPSS statistical software. Nurse entrepreneurs took a positive attitude towards management, but there were obvious shortcomings in their adoption of the manager's role. They also showed a lack of managerial assertiveness. Half of the respondents had development needs and one-third had training needs in relation to management. Nurses who are planning to start up in business should have earlier leadership experience and should attend some form of management training. The provision of care and nursing services is increasingly taking place in the private sector. This study contributes to our understanding of the managerial role of nurse entrepreneurs in this new environment.

Human immunodeficiency virus (HIV) scourge continues to affect young women within the reproductive age group and pregnancy is a recognized indication for the use antiretroviral (ARV) drugs among HIV-positive women. The aim is to determine the combined effect of pregnancy, HIV and ARV drugs on the hematological parameters of the pregnant women. This was a comparative cross-sectional study conducted among 70 each of HIV-positive and negative pregnant women. Bio-demographic and clinical data were extracted from the client folder and 4 ml of blood sample was obtained from each participant. Full blood count was generated using Swelab automatic hematology analyzer while reticulocyte count and erythrocyte sedimentation rate (ESR) were conducted manually. Data analysis was performed using SPSS version software 16 while P < 0.05 was considered statistically significant. Pregnant women with HIV had statistically significant lower hematocrit and white blood cell (WBC) and higher ESR than pregnant women without HIV ( P < 0.000). There was no statistically significant difference between the two groups in terms of platelet and reticulocyte ( P > 0.05). However, among HIV positive pregnant women, those with CD4 count <350/μL had statistically significant lower WBC and lymphocyte count than those with CD4 count ≥350/μL ( P < 0.05), whereas, those on zidovudine (AZT)-containing treatment had statistically significant lower hematocrit and higher mean cell volume than those on non-AZT-containing treatment ( P < 0.05), but there was no statistically significant difference in any of the hematological parameters ( P > 0.050) between women on first- and second-line ARV regimens. There is a significant difference in terms of hematological parameters between HIV-positive and HIV-negative pregnant women in this environment.

To determine the risk of postthyroidectomy hypocalcaemia by measuring parathyroid hormone (PTH) level after thyroidectomy. Cross-sectional study. Baqiyatallah Hospital, Tehran, Iran, from March 2008 to July 2010. All included patients were referred for total or near bilateral thyroidectomy. Serum Calcium (Ca) and PTH levels were measured before and 24 hours after surgery. In low Ca cases or development of hypocalcaemia symptoms, daily monitoring of Ca levels were continued. Data were analyzed using SPSS 20 software (SPSS, Chicago, IL, USA). A p-value less than 0.05 were considered statistically significant. To assess the standard value of useful predictive factors, we used receiver operating characteristic (ROC) curves. Of total 99 patients who underwent bilateral thyroidectomy, 47 patients (47.5%) developed hypocalcaemia, out of them, 12 (25.5%) became symptomatic while 2 patients developed permanent hypoparathyroidism. After surgery, mean rank of PTH level within the normocalcaemic and hypocalcaemic patients was 55.34 and 44.1 respectively, p=0.052. Twenty four hours after surgery, 62% drop in PTH was associated with 83.3% of symptomatic hypocalcaemic. For diagnosis of symptomatic hypocalcaemia, 62% PTH drop had sensitivity and specificity were 83.3% and 90.80%. The area under the ROC curve for the PTH postoperative and PTH drop for diagnostic symptomatic hypocalcaemia were 0.835 and 0.873 respectively. Measuring PTH levels after 24 hours postthyroidectomy is not reliable factor for predicting hypocalcaemia itself. For predicting the risk of hypocalcaemia after thyroidectomy it is more reliable to measure the serum PTH level before and after operation and compare the reduction level of percentage of PTH drop for predicting the risk of hypocalcaemia.

Medline. Clinical trials of orthodontic mini-screws with a minimum of 30 cases providing data on the patient, mini-screw, surgery and loading available for correlation with the mini-screws' success rates in English or German were included. Data were extracted that correlated with the miniscrews' success rate: patient sex and age, screw length and diameter, method and location of placement, time and amount of loading. The statistical analyses were performed using SPSS software (version 13 for Mac OS X, SPSS, Chicago, Ill). Fourteen clinical trials (452 patients and 1519 screws) were included, with overall success rates ranging from 59.4% to 100%. The mean success rate was 83.6% ± 10.2%. Screw diameters of 1 to 1.1 mm yielded significantly lower success rates than those of 1.5 to 2.3 mm. One study reported significantly lower success rates for 6 mm vs 8 mm long mini-screws (72% vs 90%). Screw placement with or without a surgical flap showed contradictory results between studies. Three studies showed significantly higher success rates for maxillary than for mandibular screws. Loading and healing periods were not significant in the mini-screws' success rates. There was no influence of patient sex and one study found significantly greater success in patients over 30 years of age. All 14 articles described success rates sufficient for orthodontic treatment. Placement protocols varied markedly. Screws under 8 mm in length and 1.2 mm in diameter should be avoided. Immediate or early loading up to 200 cN was adequate and showed no significant influence on screw stability.

Access dilation is the most important part of percutaneous nephrolithotripsy (PCNL) that is done by different methods, especially metal telescoping and one shot. In this study, two different methods of access dilation one shot and telescoping were compared. In observational cross-sectional study, 240 patients who were a candidate for PCNL were selected and randomly divided into two groups. The first group was undergone one-shot method and the second group was undergone telescoping method. The decrease in hemoglobin (Hb), duration of hospitalization and the time of radiation exposure during access dilation was compared in two groups by SPSS software version 21, (SPSS Inc., Chicago, IL, USA). The decrease of Hb level after intervention in one-shot group was 1.08 ± 1.23 g/dl and in telescoping, group was 1.51 ± 1.08 g/dl with no difference statistically ( P = 0.37). The mean duration of hospitalization in one shot and telescoping group were 2.36 ± 0.67 and 2.28 ± 0.61 days, respectively. According to t -test, there was no significant difference between the two groups ( P = 0.37). Average radiation exposure in one shot group was 7.13 s and in telescoping, group was 35.75 s, and there was a significant difference between the two groups ( P < 0.001). One-shot method is superior to telescoping method due to less time for radiation exposure and no more blood loss and other complications during PCNL.

Management of postoperative pain is a common problem in endoscopic sinus surgery. The objective of this study is the evaluation of pregabalin and acetaminophen effects on the management of postoperative pain in patients with nasal polyposis undergoing functional endoscopic sinus surgery (FESS). In this clinical trial, double-blinded study, 70 patients with nasal polyposis who have indication of FESS were enrolled to this study. After operation, patients were divided randomly into pregabalin and acetaminophen therapy groups. The pregabalin group (n = 35) was treated under pregabalin 50 mg TDS and the acetaminophen group (n = 35) was treated under tablet acetaminophen 500 mg/6 h. Each group was administered for 3 d. The visual analogue scale (VAS) was measured in onset, 12, 24, 48 and 72 h after surgery. All data were entered into SPSS software (SPSS Inc., Chicago, IL) and appropriate statistical tests were assessed to every relation. In this study, there was no significant difference between two groups according to VAS in onset (p = .37); however, VAS in 12, 24, 48 and 72 h after operation was significantly lower in the pregabalin group compared with the acetaminophen group (p < .0001, for every four). Also in the pregabalin group, adverse effects were significantly lower than the acetaminophen group (p < .03). Pregabalin has more effect, safely and usefully than acetaminophen on the management of postoperative pain in the patients with nasal polyposis undergoing functional endoscopic sinus surgery.

The vaccines against human papilloma virus are a potential tool for prevention of cervix cancer and particular other types of cancer. The high inclusion of target group in applied vaccination program is economically effective and successful activity depending in many instances on reliable knowledge and positive attitude of population to inoculation. The cross-sectional study was carried out using previously developed anonymous questionnaires for various groups of population in four pilot regions of Kazakhstan where national ministry of health proposes for inoculation of girls aged 9-13 years two vaccines against human papilloma virus (four- and two-valence) The data base was organized using software Microsoft Access. The materials were integrated and processed using variation statistics techniques in software IBM SPSS Statistics 19 and applying Student criterion and calculating correlation dependences. Out of all respondents, 66% were aware about existence of human papilloma virus/ the main portion of parents 'female adolescents learned about vaccination against human papilloma virus from Internet and medical workers. The most significant factor preventing implementation of vaccination and the proper perception by respondents was absence of confidence in safety of vaccine. About 54% of parents of female adolescents and 75% of teachers consider vaccine as unsafe. And only 72% of medical workers consider vaccine as safe. Despite known effectiveness of vaccination against human papilloma virus, number of problems exist related to implementation of program. The level of awareness and understanding of different groups of population concerning the role of vaccination in development of oncologic pathology and possibility of prevention of cancer at the expense of vaccination. The intersectoral relationships are to be developed between medicine and education system. The significance of information activities of medical control organs and organizations is to be enhanced.

A permutation test typically requires fewer assumptions than does a comparable parametric counterpart. The multi-response permutation procedure (MRPP) is a class of multivariate permutation tests of group difference useful for the analysis of experimental data. However, psychologists seldom make use of the MRPP in data analysis, in part because the MRPP is not implemented in popular statistical packages that psychologists use. A set of SPSS macros implementing the MRPP test is provided in this article. The use of the macros is illustrated by analyzing example data sets.

The aim of this study was to assess the influence of accelerated artificial aging (AAA) on the surface hardness of acrylic resins. The following three commercial brands of acrylic resins were tested: Vipi Flash (autopolymerized resin), Vipi Wave (microwave heat-polymerized resin) and Vipi Cril (conventional heat-polymerized resin). To perform the tests, 21 test specimens (65x10x3 mm) were made, 7 for each resin. Three surface hardness readings were performed for each test specimen, before and after AAA, and the means were submitted to the following tests: Kolmogorov-Smirnov (P>0.05), Levene Statistic, Two-way ANOVA, Tukey Post Hoc (P<0.05) with the SPSS Statistical Software 17.0. The analysis of the factors showed significant differences in the hardness values (P<0.05). Before aging, the autopolymerized acrylic resin Vipi Flash showed lower hardness values when compared with the heat-polymerized resin Vipi Cril (P=0.001). After aging, the 3 materials showed similar performance when compared among them. The Vipi Cril was the only one affected by AAA and showed lower hardness values after this procedure (Pp=0.003). It may be concluded that accelerated artificial aging influenced surface hardness of heat-polymerized acrylic resin Vipi Cril.

Critical-thinking ability would enable students to think creatively and make better decisions and makes them make a greater effort to concentrate on situations related to clinical matters and emergencies. This can bridge the gap between the clinical and theoretical training. Therefore, the aim of the present study is to examine the relationship between critical-thinking ability and decision-making skills of the students of Emergency Medicine. This descriptive and analytical research was conducted on all the students of medical emergency students ( n = 86) in Shahrekord, Iran. The demographic information questionnaire, the California Critical Thinking Skills Test, and a decision-making researcher-made questionnaire were used to collect data. The data were analyzed by SPSS software version 16 using descriptive and analytical statistical tests and Pearson's correlation coefficient. The results of the present study indicate that the total mean score for the critical thinking was 8.32 ± 2.03 and for decision making 8.66 ± 1.89. There is a significant statistical relationship between the critical-thinking score and decision-making score ( P < 0.05). Although critical-thinking skills and decision-making ability are essential for medical emergency professional competence, the results of this study show that these skills are poor among the students.

Construction is a key sector of the national economy for countries all over the world. Until today, construction industries are still facing lots of problems concerning the low productivity, poor safety and insufficient quality. Labour productivity is one of the factors that will give impact to the quality of projects. This study is focusing on evaluating the tile layer productivity in the area of Seberang Perai, Penang. The objective of this study is to determine the relationship of age and experience of tile layers with their productivity and to evaluate the effect of nationality to tile layers productivity. Interview and site observation of tile layers has been conducted to obtain the data of age, experience and nationality of tile layers. Site observation is made to obtain the number of tiles installed for every tile layer for the duration of 1 hour, and the data were analysed by using Statistical Package for Social Science (IBM SPSS Statistic 23) software. As a result, there is a moderate linear relationship between age and experience of tile layers with their productivity. The age of 30 and the experience of 4 years give the highest productivity. It also can be concluded that the tile layers from Indonesia tend to have higher productivity compared to tile layers from Myanmar.

Background. The extent, nature, and determinants of medication use of individuals can be known from drug utilization studies. Objectives. This study intended to determine medication consumption, sharing, storage, and disposal practices of university students in Northwest Ethiopia. Methods. A descriptive cross-sectional study was conducted on 404 university students selected through stratified random sampling technique. Data were collected using self-administered questionnaire and analyzed with SPSS version 20 statistical software. Pearson's Chi-square test of independence was conducted with P < 0.05 taken as statistically significant. Results. At 95.3% response rate, the prevalences of medication consumption and sharing were 35.3% (N = 136) and 38.2% (N = 147), respectively. One hundred (26%) respondents admitted that they often keep leftover medications for future use while the rest (N = 285, 74%) discard them primarily into toilets (N = 126, 44.2%). Evidence of association existed between medication taking and year of study (P = 0.048), medication sharing and sex (P = 0.003), and medication sharing and year of study (P = 0.015). Conclusion. There is a high prevalence of medication consumption, medication sharing, and inappropriate disposal practices which are influenced by sex and educational status of the university students. Thus medication use related educational interventions need to be given to students in general. PMID:28393101

The psychological construct of emotional intelligence (EI), its theoretical models, measurement instruments and applications have been the subject of several research studies in health professions education. The objective of the current study was to investigate the factorial validity and reliability of a bilingual version of the Schutte Self Report Emotional Intelligence Scale (SSREIS) in an undergraduate Arab medical student population. The study was conducted during April-May 2012. A cross-sectional survey design was employed. A sample (n = 467) was obtained from undergraduate medical students belonging to the male and female medical college of King Saud University, Riyadh, Saudi Arabia. Exploratory and confirmatory factor analysis was performed using SPSS 16.0 and AMOS 4.0 statistical software to determine the factor structure. Reliability was determined using Cronbach's alpha statistics. The results obtained using an undergraduate Arab medical student sample supported a multidimensional; three factor structure of the SSREIS. The three factors are Optimism, Awareness-of-Emotions and Use-of-Emotions. The reliability (Cronbach's alpha) for the three subscales was 0.76, 0.72 and 0.55, respectively. Emotional intelligence is a multifactorial construct (three factors). The bilingual version of the SSREIS is a valid and reliable measure of trait emotional intelligence in an undergraduate Arab medical student population.

There is a paucity of research exploring Indigenous women's experiences in acute mental health inpatient services in Australia. Even less is known of Indigenous women's experience of seclusion events, as published data are rarely disaggregated by both indigeneity and gender. This research used secondary analysis of pre-existing datasets to identify any quantifiable difference in recorded experience between Indigenous and non-Indigenous women, and between Indigenous women and Indigenous men in an acute mental health inpatient unit. Standard separation data of age, length of stay, legal status, and discharge diagnosis were analysed, as were seclusion register data of age, seclusion grounds, and number of seclusion events. Descriptive statistics were used to summarize the data, and where warranted, inferential statistical methods used SPSS software to apply analysis of variance/multivariate analysis of variance testing. The results showed evidence that secondary analysis of existing datasets can provide a rich source of information to describe the experience of target groups, and to guide service planning and delivery of individualized, culturally-secure mental health care at a local level. The results are discussed, service and policy development implications are explored, and suggestions for further research are offered. © 2016 Australian College of Mental Health Nurses Inc.

Background and Aims: Critical-thinking ability would enable students to think creatively and make better decisions and makes them make a greater effort to concentrate on situations related to clinical matters and emergencies. This can bridge the gap between the clinical and theoretical training. Therefore, the aim of the present study is to examine the relationship between critical-thinking ability and decision-making skills of the students of Emergency Medicine. Materials and Methods: This descriptive and analytical research was conducted on all the students of medical emergency students (n = 86) in Shahrekord, Iran. The demographic information questionnaire, the California Critical Thinking Skills Test, and a decision-making researcher-made questionnaire were used to collect data. The data were analyzed by SPSS software version 16 using descriptive and analytical statistical tests and Pearson's correlation coefficient. Results: The results of the present study indicate that the total mean score for the critical thinking was 8.32 ± 2.03 and for decision making 8.66 ± 1.89. There is a significant statistical relationship between the critical-thinking score and decision-making score (P < 0.05). Conclusions: Although critical-thinking skills and decision-making ability are essential for medical emergency professional competence, the results of this study show that these skills are poor among the students.

Climate change and vulnerability are major challenges in ensuring household food security. Climate information services have the potential to cushion rural households from extreme climate risks. However, most the probabilistic nature of climate information products is not easily understood by majority of smallholder farmers. Despite the probabilistic nature, climate information have proved to be a valuable climate risk adaptation strategy at the farm level. This calls for innovative ways to help farmers understand and apply climate information services to inform their farm level decisions. The study endeavored to co-design and test appropriate innovation systems for climate information services uptake and scale up necessary for achieving climate risk development. In addition it also determined the conditions necessary to support the effective performance of the proposed innovation system. Data and information sources included systematic literature review, secondary sources, government statistics, focused group discussions, household surveys and semi-structured interviews. Data wasanalyzed using both quantitative and qualitative data analysis techniques. Quantitative data was analyzed using the Statistical Package for Social Sciences (SPSS) software. Qualitative data was analyzed using qualitative techniques, which involved establishing the categories and themes, relationships/patterns and conclusions in line with the study objectives. Sustainable livelihood, reduced household poverty and climate change resilience were the impact that resulted from the study.

Since almost half of the child abuse cases affect the head and neck region, dentists have an important role in the diagnosis and report of oral and dental aspects of child abuse cases. The objective of the current study was to evaluate the knowledge, attitude and practice of the general dentists and pedodontists regarding child abuse and child neglect. This cross-sectional study was carried out on the participants of the 12 th congress of pedodontists of Iran. A self-administered questionnaire was used for evaluating their knowledge, attitude and practice toward child abuse. T-test and ANOVA were applied to analyze the data by SPSS software. p <0.05 was considered statistically significant. The mean score of knowledge, attitude and practice of the participants regarding child abuse was 10.24±2.68, 41.54±11.24 and 2.78±1.05, respectively. The knowledge of pedodontists was significantly higher than knowledge of general dentists. No statistically significant difference was observed in attitude and practice ( p > 0.05). Dentists had a moderate knowledge, poor attitude and moderate practice regarding child abuse. Considering this fact, improvements in child abuse education for undergraduate students and continuing post-graduate training in this field are recommended.

Background. The extent, nature, and determinants of medication use of individuals can be known from drug utilization studies. Objectives. This study intended to determine medication consumption, sharing, storage, and disposal practices of university students in Northwest Ethiopia. Methods. A descriptive cross-sectional study was conducted on 404 university students selected through stratified random sampling technique. Data were collected using self-administered questionnaire and analyzed with SPSS version 20 statistical software. Pearson's Chi-square test of independence was conducted with P < 0.05 taken as statistically significant. Results. At 95.3% response rate, the prevalences of medication consumption and sharing were 35.3% ( N = 136) and 38.2% ( N = 147), respectively. One hundred (26%) respondents admitted that they often keep leftover medications for future use while the rest ( N = 285, 74%) discard them primarily into toilets ( N = 126, 44.2%). Evidence of association existed between medication taking and year of study ( P = 0.048), medication sharing and sex ( P = 0.003), and medication sharing and year of study ( P = 0.015). Conclusion. There is a high prevalence of medication consumption, medication sharing, and inappropriate disposal practices which are influenced by sex and educational status of the university students. Thus medication use related educational interventions need to be given to students in general.

The objectives of this paper were to evaluate pre- to post-treatment outcomes of patients attending a student-run free physical therapy clinic in order to provide new evidence concerning patient response to student care. We hypothesize improved functional and quality of life scores as measured by outcome scales. Twenty-eight patients were included in this retrospective chart review. Data were analyzed through SPSS Statistical software (ver. 13) using paired t-tests to compare baseline and follow-up data for the following measures: blood pressure, numeric pain rating scale (NPRS), quality of life visual analog scale, SF-8 quality of life scale, and population demographics. Most of the patient population was between the ages of 30 and 59 yrs (78.4%) with an unemployment rate of 75%. Significant changes (p<0.05) were exhibited in both the physical health portion of the SF-8 survey and the NPRS. Although not statistically significant, the mental health portion of the SF-8 survey showed notable improvement. Service learning provides opportunities for students to serve the community while expanding clinical experience. The results demonstrated the effectiveness of student-run pro-bono physical therapy clinics in improving the quality of life for both physical and pain measures.

Aims To explore dental hygiene and dental therapy students' (DHDTS') perception of stress and well-being during their undergraduate education and establish base-line data for further studies of this group of dental professionals.Subjects and methods A questionnaire was distributed to Years 1, 2 and 3 DHDTS and final year outreach dental students (DS) (as a comparison group), at the University of Portsmouth Dental Academy (UPDA), during summer 2015. Data were collected on students' perception of levels of stress and well-being. Statistical analyses were undertaken using SPSS software. Mann-Whitney U tests with Bonferroni corrections were used and the level for a statistically significant difference was set at p <0.002.Results A response rate of 81% (DHDTS) and 85% (DS) was achieved. Clinical factors and academic work were perceived as stressful for both DHDTS and DS, with no significant difference between the groups. The majority of respondents reported levels of depression, anxiety, and stress to be within the normal range. All students reported high levels of positive well-being, with DHDTS scoring significantly higher than DS in the dimensions of personal growth, purpose in life, self-acceptance and positive relations with others (p <0.002).Conclusions DHDTS and DS identified sources of stress within their undergraduate education, but also perceived themselves as positively-functioning individuals.

According to our knowledge, there has never been a comprehensive research in Hungary dealing with healthcare university or college students' social background. The main objectives of our cross-section research were to analyze differences in the social background of female students who decided to become doctors, professional nurses and health visitors. This research was conducted among female medical and nursing college students at the Semmelweis University. There were 295 students invited to participate, the response rate was 68,08% (N = 201). Data analysis was performed by SPSS software by using descriptive methods of statistics. We found a decisive difference among medical, nursing and health visitor students while analyzing a number of socio-demographic characteristics. Most medical students came from families where the parents had college or university degrees, but we can state that there is a minimal likelihood in the case of college students that they are descendants of parents with higher educational degrees. We did not find statistical differences in the three student sample groups regarding their marital status, but fewer nursing college students lived in marriage or household partnership. We found a significant difference in the social background of nursing college and medical students. The social disadvantages of nursing and health visitor students are more considerable than those of medical students.

The aims of this study were to investigate the prevalence of neck pain among computer workers at Hail University, Saudi Arabia and to compare the cervical range of motion (ROM) of female computer workers suffering from neck pain to the cervical ROM of healthy female computer workers. One hundred and seventy-six female volunteers between 20 and 46 years of age were investigated. Fifty-six of these volunteers were staff members, 22 were administrators and 98 were students. The Cervical Range of Motion (CROM) instrument was used to measure the ROM of the cervical spine. A questionnaire was used to assess participants for the presence of neck pain. The data were analyzed using the Statistical Package for Social Sciences (SPSS) software, and the level of significant was set at p < .05 for all statistical tests. There was a high prevalence of neck pain (75%) among computer workers at Hail University, particularly among students. There were significant differences in cervical lateral flexion, rotation to the right side and protraction range between the pain and pain-free groups. Our results demonstrated that cervical ROM measurements, particularly cervical lateral flexion, rotation and protraction, could be useful for predicting changes in head and neck posture after long-term computer work.

Mobbing, defined as sustained harassment among workers, in particular towards subordinates, merits investigation. This study aims to investigate Slovenian midwifery students' (2nd and 3rd year students of midwifery at the Faculty for Health Studies Ljubljana; the single educational institution for midwives in Slovenia) perception of mobbing, since management of acceptable behavioural interrelationships in midwifery profession forms already during the study, through professional socialization. Descriptive and causal-nonexperimental method with questionnaire was used. Basic descriptive statistics and measures for calculating statistical significance were carried out with SPSS 20.0 software version. All necessary ethical measures were taken into the consideration during the study to protect participants. The re- sults revealed that several participants experienced mobbing during the study (82.3%); 58.8% of them during their practical training and 23.5% from midwifery teachers. Students are often anxious and nervous in face of clinical settings (60.8%) or before faculty commitments (exams, presentations etc.) (41.2%). A lot of them (40.4%) estimate that mobbing affected their health. They did not show effective strategies to solve relationship problems. According to the findings, everyone involved in midwifery education, but above all students, should be provided with more knowledge and skills on successful management of conflict situations.

The purpose of this study was to investigate the effect of aromatherapy massage on the severity of primary dysmenorrhea in nursing and midwifery students of Islamic Azad University of Arsanjan, Iran. Materials and Methods: This study was performed using clinical trial method on 80 eligible students whose level of pain was measured by visual analogue scale (VAS) before the intervention. Each participant, in the first days of menstruation, randomly received two types of massage with lavender and placebo oil in two consecutive cycles of menstruation. Their level of pain was measured before and 30 min after the intervention. In this study, each group was considered as their self-control group in the next cycle. The data were analyzed by SPSS software. Results: A significant decrease in VAS score after lavender massage was detected in comparison with placebo massage. There was a statistically significant difference between VAS scores after and before placebo massage. In addition, statistically the effect of lavender massage on the severity of primary dysmenorrhea was higher than that of placebo massage (P < 0.001). Conclusions: Findings of this study showed that lavender oil massage decreases primary dysmenorrhea and it can be used as an effective herbal drug. PMID:25709705

Background. Cervical cancer caused by human papilloma virus (HPV) though preventable has claimed the lives of many women worldwide. This study was embarked upon to evaluate the general knowledge and perceptions of Nigerian women on HPV, cervical cancer, and HPV vaccine. Methods. Structured questionnaires were administered to a cross section of 737 women randomly selected from the general population in two southwestern States of Nigeria. Statistical analysis was done using SPSS computer software version 16. A P value >0.05 was considered statistically significant. Results. One hundred and seventy-six (23.9%) of the respondents had knowledge of HPV; 474 (64.3%) are aware of cervical cancer but only 136 (18.5%) know that HPV causes cervical cancer. 200 (27.1%) are aware that there is an HPV vaccine while 300 (40.7%) had knowledge of Pap smear test. Two hundred and sixty (35.3%) of the respondents know that early detection of HPV can prevent cervical cancer and in spite of this, only 110 (14.9%) have taken the Pap smear test before while 151 (20.5%) are not willing to go for the test at all. Conclusions. There is therefore the need to create proper awareness on the HPV and its possible consequence of cervical carcinoma. PMID:26550522

Since appropriate and time-table methods in trauma care have an important impact on patients'outcome, we evaluated the effect of Advanced Trauma Life Support (ATLS) program on medical interns' performance in simulated trauma patient management. A descriptive and analytical study before and after the training was conducted on 24 randomly selected undergraduate medical interns from Imam Reza Hospital in Mashhad, Iran. On the first day, we assessed interns' clinical knowledge and their practical skill performance in confronting simulated trauma patients. After 2 days of ATLS training, we performed the same study and evaluated their score again on the fourth day. The two findings, pre- and post- ATLS periods, were compared through SPSS version 15.0 software. P values less than 0.05 were considered statistically significant. Our findings showed that interns'ability in all the three tasks improved after the training course. On the fourth day after training, there was a statistically significant increase in interns' clinical knowledge of ATLS procedures, the sequence of procedures and skill performance in trauma situations (P less than 0.001, P equal to 0.016 and P equal to 0.01 respectively). ATLS course has an important role in increasing clinical knowledge and practical skill performance of trauma care in medical interns.

Violence within the family is a significant health problem which threatens the health of the community. The global rates of domestic violence directed at women have been reported as 10%-69% and in Turkey as 25%-30%. The data of our study were obtained from the database of the official internet website of the Turkish Statistics Institute as the data related to violence between 2007 and 2012. In the evaluation of the data, SPSS 11.0 statistics software was used. Although it was determined that women from all groups experienced sexual, physical and emotional violence, higher rates were observed in those living in rural areas compared to those in urban areas, in the eastern region compared to all other regions, in the 45-59 years age group, those with low level of income and with a low level of education. When physicians encounter women who have experienced violence, by evaluating the violence in the context of a legal case, violence is identified and not allowed to become a cycle passed from generation to generation, and in addition to the medical intervention, without forgetting that violence is a public health problem, it is necessary to find a way to provide psychosocial and legal support for the victim.

The objective of this study was to determine the effect of the computer-based educational package on men's QoL and the severity of their hypogonadism symptoms. A quasi-experimental study was conducted on 80 male employees. The data collection tool included the 'Aging Male Symptoms' (AMS) and 'Short Form-36' (SF36) questionnaires. Four sessions were held for the intervention group over a period of 4 weeks. Two months after training, QoL and the severity of hypogonadism symptoms were measured in both the intervention and control groups. The data were analyzed with SPSS 22 software and statistical tests, such as χ 2 , independent t-test, Fisher's exact test, and paired t-tests. Significant statistical changes were observed in the intervention group before and 2 months after the training in the QoL score in the overall dimensions of physical-psychological health and all its domains except for three domains of emotional role, social function, and pain. Furthermore, the paired t-tests showed significant differences between 2 months before and after the training in all the domains and the overall hypogonadism score in the intervention group. Based on our findings, the computer-based educational package has a positive effect on QoL and reduction of hypogonadism symptoms.

Today, it is acknowledged that smoking during pregnancy and/or the postnatal period has significant risks for a foetus and newborn child. This research examines the relationship between smoking only postnatally, both during pregnancy and postnatally, and the newborn sex, birth weight and breastfeeding. Total 664 women of randomly selected five primary healthcare centres between the dates 20 February 2010 and 20 July 2010 were included in the research. Statistical analyses were performed with SPSS for Windows 19.0 (Statistical Package for Social Sciences software package). Data were described as mean, standard deviation, percentages and Chi-square tests and backward stepwise logistic regression were analysed. It was found that the percentage of smoking women with daughters is 2.5 times higher than women with sons. Women who smoke are 3.9 times more likely to start feeding their baby with supplementary infant foods at 4 months or earlier than those who do not smoke. Finally, the risk of a birth weight under 2500 g is 3.8 times higher for maternal smokers. This study suggests that women who expect a girl smoke more heavily than those who expect a boy. The birth weight of maternal smokers' newborns is lower. Those women who smoke while breastfeeding start feeding their babies with supplementary infant foods at an earlier age.

The aim of this study is to compare calculated free testosterone (cFT) and total testosterone (T) in predicting late-onset hypogonadism (LOH) in middle-aged and elderly males. We surveyed a random sample of 608 males between the ages of 45 and 87 years from Shanghai, China. The Aging Male Symptoms (AMS) questionnaire and the Androgen Deficiency in Aging Male (ADAM) questionnaire were completed by the subjects. Testosterone (T), sex hormone-binding globulin (SHBG), albumin, and other blood biochemical indexes were measured in 332 males. The corresponding cFT was obtained using the Vermeulen formula and the correlations between T and cFT were analyzed by SPSS statistical software. Among the 332 males who underwent biochemical evaluation, 289 males (87.0%) was positively screened by the ADAM questionnaire and 232 males (69.9%) by the AMS questionnaire. As suggested by linear regression, cFT exhibited a negative correlation with age in both ADAM+ and AMS+ group, whereas T did not appear to have significant correlation with age. Besides, there were statistically significant differences in cFT (P<.001) in the AMS questionnaire. Calculated free testosterone levels are more reliable than T levels for diagnosing LOH in middle-aged and elderly males. © 2016 Wiley Periodicals, Inc.

Cheung, Shu Fai; Chan, Darius K-S

2014-06-01

The presence of dependent correlation is a common problem in meta-analysis. Cheung and Chan (2004, 2008) have shown that samplewise-adjusted procedures perform better than the more commonly adopted simple within-sample mean procedures. However, samplewise-adjusted procedures have rarely been applied in meta-analytic reviews, probably due to the lack of suitable ready-to-use programs. In this article, we compare the samplewise-adjusted procedures with existing procedures to handle dependent effect sizes, and present the samplewise-adjusted procedures in a way that will make them more accessible to researchers conducting meta-analysis. We also introduce two tools, an SPSS macro and an R script, that researchers can apply to their meta-analyses; these tools are compatible with existing meta-analysis software packages.

Clinical reasoning is one of the most important skills in the process of training a medical student to become an efficient physician. Assessment of the reasoning skills in a medical school program is important to direct students' learning. One of the tests for measuring the clinical reasoning ability is Clinical Reasoning Problems (CRPs). The major aim of this study is to measure psychometric qualities of CRPs and define correlation between this test and routine MCQ in cardiology department of Shiraz medical school. This study was a descriptive study conducted on total cardiology residents of Shiraz Medical School. The study population consists of 40 residents in 2014. The routine CRPs and the MCQ tests was designed based on similar objectives and were carried out simultaneously. Reliability, item difficulty, item discrimination, and correlation between each item and the total score of CRPs were all measured by Excel and SPSS software for checking psycometeric CRPs test. Furthermore, we calculated the correlation between CRPs test and MCQ test. The mean differences of CRPs test score between residents' academic year [second, third and fourth year] were also evaluated by Analysis of variances test (One Way ANOVA) using SPSS software (version 20)(α=0.05). The mean and standard deviation of score in CRPs was 10.19 ±3.39 out of 20; in MCQ, it was 13.15±3.81 out of 20. Item difficulty was in the range of 0.27-0.72; item discrimination was 0.30-0.75 with question No.3 being the exception (that was 0.24). The correlation between each item and the total score of CRP was 0.26-0.87; the correlation between CRPs test and MCQ test was 0.68 (p<0.001). The reliability of the CRPs was 0.72 as calculated by using Cronbach's alpha. The mean score of CRPs was different among residents based on their academic year and this difference was statistically significant (p<0.001). The results of this present investigation revealed that CRPs could be reliable test for measuring clinical reasoning in residents. It can be included in cardiology residency assessment programs.

Opening Pandora's Box: Texas Elementary Campus Administrators use of Educational Policy And Highly Qualified Classroom Teachers Professional Development through Data-informed Decisions for Science Education

NASA Astrophysics Data System (ADS)

Brown, Linda Lou

Federal educational policy, No Child Left Behind Act of 2001, focused attention on America's education with conspicuous results. One aspect, highly qualified classroom teacher and principal (HQ), was taxing since states established individual accountability structures. The HQ impact and use of data-informed decision-making (DIDM) for Texas elementary science education monitoring by campus administrators, Campus Instruction Leader (CILs), provides crucial relationships to 5th grade students' learning and achievement. Forty years research determined improved student results when sustained, supported, and focused professional development (PD) for teachers is available. Using mixed methods research, this study applied quantitative and qualitative analysis from two, electronic, on-line surveys: Texas Elementary, Intermediate or Middle School Teacher Survey(c) and the Texas Elementary Campus Administrator Survey(c) with results from 22.3% Texas school districts representing 487 elementary campuses surveyed. Participants selected in random, stratified sampling of 5th grade teachers who attended local Texas Regional Collaboratives science professional development (PD) programs between 2003-2008. Survey information compared statistically to campus-level average passing rate scores on the 5th grade science TAKS using Statistical Process Software (SPSS). Written comments from both surveys analyzed with Qualitative Survey Research (NVivo) software. Due to the level of uncertainty of variables within a large statewide study, Mauchly's Test of Sphericity statistical test used to validate repeated measures factor ANOVAs. Although few individual results were statistically significant, when jointly analyzed, striking constructs were revealed regarding the impact of HQ policy applications and elementary CILs use of data-informed decisions on improving 5th grade students' achievement and teachers' PD learning science content. Some constructs included the use of data-warehouse programs; teachers' applications of DIDM to modify lessons for differentiated science instruction, the numbers of years' teachers attended science PD, and teachers' influence on CILs staffing decisions. Yet CILs reported 14% of Texas elementary campuses had limited or no science education programs due to federal policy requirement for reading and mathematics. Three hypothesis components were supported and accepted from research data resulted in two models addressing elementary science, science education PD, and CILs impact for federal policy applications.

Background: Human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) is a lifestyle-related disease. This disease is transmitted through unprotected sex, contaminated needles, infected blood transfusion and from mother to child during pregnancy and delivery. Prevention of infection with HIV, mainly through safe sex and needle exchange programmes is a solution to prevent the spread of the disease. Knowledge about HIV state helps to prevent and subsequently reduce the harm to the later generation. The purpose of this study was to assess the willingness rate of couples referred to the family regulation pre-marital counselling centre for performing HIV test before marriage in Yazd. Patients and Methods: In this descriptive study, a simple random sampling was done among people referred to Akbari clinic. The couples were 1000 men and 1000 women referred to the premarital counselling centre for pre-marital HIV testing in Yazd in the year 2012. They were in situations of pregnancy, delivery or nursing and milking. The data were analyzed using Statistical Package for the Social Sciences (SPSS) software and chi-square statistical test. Results: There was a significant statistical difference between the age groups about willingness for HIV testing before marriage (P < 0.001) and also positive comments about HIV testing in asymptomatic individuals (P < 0.001). This study also proved a significant statistical difference between the two gender groups about willingness to marry after HIV positive test of their wives. Conclusion: The willingness rate of couples to undergo HIV testing before marriage was significant. Therefore, HIV testing before marriage as a routine test was suggested. PMID:25114363

As coffee consumption is increasing remarkably over the past decade, the health effects concerning the coffee drinking has gained a wide attention across the nation. However, there is not a true consensus regarding the effects of coffee on metabolic disease. Therefore, this study aims to examine the association between coffee intake and the risk of metabolic syndrome in Korean women. We used publicly accessible datasets collected through Korean National Health and Nutrition Examination Survey (KNHANES). Among 20,435 individuals from five consecutive years' worth of data from 2007 to 2011, only 15,691 subjects qualified for statistical analysis upon applying the exclusion criteria. We carried out the statistical analysis utilizing SPSS Statistics version 13.0 (IBM Corp., Armonk, NY.) and STATA statistical software release 13.0 (STATA Corp., College Station, TX). We found that the frequency of coffee intake inversely correlates with the prevalence of metabolic syndrome in women. Upon adjusting for life-style factors, socioeconomic status, and nutritional profile, the subjects from the highest coffee consumption quartile exhibited 40% lower odds of suffering from metabolic syndrome compared to those in the control (OR = 0.75; 95% CI = 0.67-0.84; P for trend < 0.001). Also, we observed that age- and BMI-adjusted HOMA-IR decreased as the coffee consumption increased (P for trend < 0.001). The findings of our study suggest that coffee consumption might be associated with reduction of metabolic syndrome in Korean women. To elucidate this cross-sectional association between coffee consumption and metabolic syndrome in women, cohort studies are warranted to confirm this relationship.

To assess and compare the knowledge of basic life support (BLS) among third, fourth and fifth (III, IV and V) year Bachelor of Dental Surgery (BDS) clinical students, dental interns, postgraduate students and Bachelor of Dental Surgery (BDS) and Master of Dental Surgery (MDS) faculty of Panineeya Institute of Dental Sciences and Hospital, Hyderabad, India. A BLS questionnaire consisting of 22 questions was used to assess the levels of III, IV and V years BDS clinical students, dental interns, postgraduate students and BDS and MDS faculty of Panineeya Institute of Dental Sciences and Hospital, Hyderabad, India. Statistical Package for Social Sciences software (SPSS version 12.0) was used to analyze the statistical data. The p<0.05 was considered statistically significant. A total of 338 respondents took part in the study. When gender comparison was done with correct knowledge responses, statistically significant differences were noted for Q6, Q9, Q12, Q13, Q15 and Q17. For age groups and educational qualifications, significant difference was observed for all questions. It was noted that III, IV and V year undergraduate clinical students and half of interns had adequate knowledge when compared to postgraduate students (6.9%), BDS tutors (0.00%) and MDS staff (10.7%). The study concludes that there is a significant lack of knowledge among postgraduates students BDS and MDS faculty, regarding BLS when compared to III, IV and V year's clinical BDS students and dental interns. This study emphasizes the need for all health care professionals to regularly update the knowledge and skills regarding BLS.

Aims and Objectives: The objective of the present study is to compare the effectiveness of three different processing techniques and to find out the accuracy of processing techniques through number of occlusal interferences and increase in vertical dimension after denture processing. Materials and Methods: A cross-sectional study was conducted on a sample of 18 patients indicated for complete denture fabrication was selected for the study and they were divided into three subgroups. Three processing techniques, compression molding and injection molding using prepolymerized resin and unpolymerized resin, were used to fabricate dentures for each of the groups. After processing, laboratory-remounted dentures were evaluated for number of occlusal interferences in centric and eccentric relations and change in vertical dimension through vertical pin rise in articulator. Data were analyzed using statistical test ANOVA and SPSS software version 19.0 by IBM was used. Results: Data obtained from three groups were subjected to one-way ANOVA test. After ANOVA test, results with significant variations were subjected to post hoc test. Number of occlusal interferences with compression molding technique was reported to be more in both centric and eccentric positions as compared to the two injection molding techniques with statistical significance in centric, protrusive, right lateral nonworking, and left lateral working positions (P < 0.05). Mean vertical pin rise (0.52 mm) was reported to more in compression molding technique as compared to injection molding techniques, which is statistically significant (P < 0.001). Conclusions: Within the limitations of this study, injection molding techniques exhibited less processing errors as compared to compression molding technique with statistical significance. There was no statistically significant difference in processing errors reported within two injection molding systems. PMID:28713763

To explore the performance patterns of reaction point Jingtong in balance acupuncture through multi-center and big-sample clinical investigation. Methods The Jingtong points of balance acupuncture on healthy side and affected side were observed among 230 cases of cervical spondylosis and scores of self-discomfort in reaction point, color of skin, changes of skin, morphology of subcutaneous tissue and abnormal pressing pain were recorded. The software SPSS 15.0 was applied to statistically analyze the recorded scores. Among 230 cases, the reaction point appeared in 226 cases, accounting for 98. 3%. Among the 226 cases who had reaction point, the total score of symptom and sign was (1.08+/-1.09) on the healthy side and (0. 84+/-1. 36) on the affected side, which had statistical significance (P<0. 01); score of self-discomfort in reaction point was (0. 76 +/-0. 83) on the healthy side and (0. 40+/-0.80) on the affected side, which had statistical significance (P<0.01); the score of skin color was (0.10+/-0.36) on the healthy side and (0. 03+/- 0. 19) on the affected side, which had statistical significance (P<0. 05); the score of abnormal pressing pain was (2. 47+/-2. 46) on the healthy side and (1. 39+/-2. 37) on the affected side, which had statistical significance (P<0. 01). The total score of symptom and sign of reaction point Jingtong on the healthy side is higher than that on the affected side, indicating positive reaction of Jingtong on the healthy side has specificity for cervical spondylosis. When patient has cervical spondylosis on either side of neck, the other side will have anomaly in Jingtong.

A new data bank developed for ophthalmopathology using a computer-generated, multidigital data code is expected to be able to accomplish complex clinicopathologic correlations of diagnoses and signs, as provided by (multiple) clinical events and histopathologically proven etiologies, and to facilitate the documentation of new data. In the ophthalmopathology laboratory 2890 eyes were examined between January 20, 1975 and December 12, 1996. The main diagnoses and patient data from this 22-year period were recorded. To facilitate the presentation of data, a 10-year period with eyes of 976 patients enucleated from December, 1986 to December, 1996 was chosen. Principal and secondary diagnoses served for establishing the data bank. The frequencies of successive histologic and clinical diagnoses were evaluated by a descriptive computing program using an SPSS-multi-response mode with dummy variables and a categorical variable listing of the software (SPSS version 10.0) classified as (a) non-filtered random, (b) filtered by multiple etiologies, and (c) filtered by multiple events. The principal groups (e.g., histologic diagnoses concerning etiology) and subgroups (e.g., trauma, neoplasia, surgery, systemic diseases, and inflammations) were defined and correlated with 798 separate diagnoses. From 11 diagnoses/events ascribed to the clinical cases, 11,198 namings resulted. Thus, a comparative study of complex etiologies and events leading to enucleation in different hospitals of a specific area may be performed using this electronic ophthalmopathologic data bank system. The complexity of rare disease and integration into a superimposed structure can be managed with this custom-made data bank. A chronologically and demographically oriented consideration of reasons for enucleation is thus feasible.

Introduction Time management skills are essential for nursing students’ success, and development of clinical competence. The purpose of this study was to determine the relationship between time management skills and anxiety and academic motivation of nursing students in Tehran medical sciences universities in 2015. Methods This cross-sectional study was carried out on 441 nursing students in three medical universities in Tehran. Random stratified sampling was done to select the samples. Data were collected using demographic Questionnaire, Time Management Questionnaire (TMQ), Spielberger State-Trait Anxiety Inventory (STAI) and Academic Motivation Scale (AMS), which was completed t by self-report. Data were analyzed using SPSS 18 software with descriptive and analytical statistics such as ANOVA, independent t-test, Regression and Pearson Correlation Coefficient. Results Most participants had a moderate level of time Management skills (49%), State Anxiety (58%), Trait Anxiety (60%) and Academic Motivation (58%). The results also showed a statistically significant negative correlation between the students’ TMQ scores and the state anxiety (r= −0.282, p< 0.001) and trait anxiety scores (r= −0.325, p<0.001). Moreover, there was a statistically significant positive correlation between the students’ TMQ scores and AMS scores (r= 0.279, p< 0.001). Conclusion Regarding the findings, it seems that it is necessary to plan for improving time management skills in order to enhance academic motivation and reduce anxiety rates among nursing students.

Objectives: To evaluate the in vitro growth inhibition of Candida albicans, in the soft-liner material and Shore A hardness from resin-based denture soft lining materials modified by neem or garlic incorporation. Materials and Methods: Resin discs were prepared with poly methyl methacrylate (PMMA) and soft liners incorporated with varying concentrations of neem or garlic. For antifungal activity, resin discs were placed on agar plates inoculated with C. albicans and were evaluated after 2, 4, and 7 days using the streaking method. The hardness of the PMMA was evaluated with the use of Shore A at 2, 4, and 7 days. Data were statistically processed by SPSS software (IBM Company, Chicago, USA) using Kruskal–Wallis test, and post hoc comparisons were done using Dunn's test. P <0.05 was considered statistically significant. Results: Neem and garlic added to PMMA soft liner had an inhibitory effect on C. albicans. Both the neem and garlic when added showed positive results against C. albicans when compared to the control group. The soft liner hardness increased statistically by time but not for the different plant extract concentrations. Conclusions: Within the limitations of this in vitro study, it was found that neem and garlic can be used as an additive to tissue conditioner to reduce the adherence of C. albicans without significantly affecting the hardness of the heat-polymerized acrylic resin.

Various components of fixed orthodontic appliances are continuously interacting with saliva and other fluids in the mouth releasing various metal ions including nickel and chromium that can cause damaging effects if their concentration exceeds above the toxic dose. To determine and compare the level of nickel and chromium in the saliva of patients undergoing fixed orthodontic treatment at different time periods. The sample of saliva of 13 patients was taken at different time periods that is: Group 1 (before appliance placement), Group II, III, and IV (after 1-week, 1-month, and 3 months of appliance placement respectively). The fixed appliance comprised of brackets, bands, buccal tubes, lingual sheath, transpalatal arch and wires composed of Ni-Ti and stainless steel. The level of ions was determined using graphite furnace atomic absorption spectro-photometry. The data thus obtained were statistically analyzed using SPSS Statistical Analysis Software (Version 15.0). Level of nickel and chromium in saliva was highest in Group II and lowest in Groups I for both the ions. On comparison among different Groups, it was statistically significant for all the groups (<0.001) except between Group III and Group IV. The release of nickel and chromium was maximum at 1-week and then the level gradually declined. These values were well below the toxic dose of these ions. The results should be viewed with caution in subjects with Ni hypersensitivity.

Background and aims: This study is to compare the short-term and long-term mortality in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS) after percutaneous coronary intervention (PCI). Methods and results: A total of 266 STEMI patients and 140 NSTE-ACS patients received PCI. Patients were followed up by telephone or at medical record or case statistics center and were followed up for 4 years. Descriptive statistics and multivariate survival analyses were employed to compare the mortality in STEMI and NSTE-ACS. All statistical analyses were performed by SPSS19.0 software package. NSTE-ACS patients had significantly higher clinical and angiographic risk profiles at baseline. During the 4-year follow-up, all-cause mortality in STEMI was significantly higher than that in NSTE-ACS after coronary stent placement (HR 1.496, 95% CI 1.019-2.197). In a landmark analysis no difference was seen in all-cause mortality for both STEMI and NSTE-ACS between 6 month and 4 years of follow-up (HR 1.173, 95% CI 0.758-1.813). Conclusions: Patients with STEMI have a worse long-term prognosis compared to patients with NSTE-ACS after PCI, due to higher short-term mortality. However, NSTE-ACS patients have a worse long-term survival after 6 months. PMID:25664077

Background Bronchial asthma is an important health problem worldwide. There is insufficient data on the prevalence of bronchial asthma among school children in Santo Domingo, Dominican Republic. Objective The objective of this study is to assess the prevalence of asthma and its related risk factors among school children in Santo Domingo, Dominican Republic. Materials and methods A cross-sectional study using a modified questionnaire was conducted in Santo Domingo among 600 children aged three to 11 eleven years. The prevalence of asthma and its associated risk factors such as birth order, family history of asthma, family history of allergy, exposure to pets at home, exposure to tobacco smoke, and source of fuel used at home were collected. The relevant data collected was analyzed using the Statistical Package for the Social Sciences (SPSS) 24.0. (IBM Corp., Armonk, NY) software. Results The prevalence of asthma was found to be 22.0%. Age, family history of asthma, family history of allergy, exposure to tobacco smoke, and birth order showed statistical significance. The source of fuel used at home, gender, and exposure to pets were not statistically significant to be considered as risk factors associated with asthma in the population studied. Conclusion With an asthma prevalence of 22.0% in the pediatric population, the Dominican Republic has one of the highest national rates of asthma in the pediatric population in Latin America. Proper education, screening, and prevention can help lower the burden of this disease economically and socially.

Oligohydramnios is described as decreased amniotic fluid volume relative to gestational age. Semiquantitatively it is described using the Amniotic Fluid Index (AFI) which is calculated by adding the depth in centimetres of the largest vertical pocket in each of four equal uterine quadrants. AFI less than or equal to 5 cm is defined as oligohydramnios. A Borderline Oligohydramnios (BO) is defined as AFI 5.1-8 cm. To assess the maternal and perinatal outcome of induction in borderline oligohydramnios cases at term. This is a retrospective observational study done from December 2015 to November 2016 in Mahatma Gandhi Medical College and Research Institute, Puducherry, India. Fifty cases of BO with AFI 5.1 cm - 8 cm taken as case and another 50 cases of Normal Liquor (NL) with AFI 8.1 cm - 18 cm taken as control. Data was collected and analysed by SPSS software version 20.0 For qualitative data, the χ 2 -test or Fisher's-exact test were used and for continuous variables, the t-test was used. Cases and controls were matched in baseline parameters. More number of cases were found with meconium stained liquor during labour which is statistically significant (p<0.05). Otherwise there were no statistical significant difference between cases and controls in maternal and perinatal outcome. Induction of labour in cases with BO cases compared to those with NL at term did not show very statistically significant difference in terms of induction to delivery interval and neonatal outcome.

Due to the widespread use of mobile technology and the low cost of this technology, implementing a mobile-based self-management system can lead to adherence to the medication regimens and promotion of the health of people living with HIV (PLWH). We aimed to identify requirements of a mobile-based self-management system, and validate them from the perspective of infectious diseases specialists. This is a mixed-methods study that carried out in two main phases. In the first phase, we identified requirements of a mobile-based self-management system for PLWH. In the second phase, identified requirements were validated using a researcher made questionnaire. The statistical population was infectious diseases specialists affiliated to Tehran University of Medical Sciences. The collected data were analyzed using SPSS statistical software (version 19), and descriptive statistics. By full-text review of selected studies, we determined requirements of a mobile-based self-management system in four categories: demographic, clinical, strategically and technical capabilities. According to the findings, 6 data elements for demographic category, 11 data elements for clinical category, 10 items for self-management strategies, and 11 features for technical capabilities were selected. Using the identified preferences, it is possible to design and implement a mobile-based self-management system for HIV-positive people. Developing a mobile-based self-management system is expected to progress the skills of self-management PLWH, improve of medication regimen adherence, and facilitate communication with healthcare providers.

To investigate the clinical effect of eruption guidance appliance in the treatment of anterior cross bite in mixed-dentition children. In the study,10 mixed-dentition children with anterior cross bite, totally 12 incisors, were selected. Alginate was used to take upper and lower dentition impression and make a hard plaster model,which served as the eruption guidance appliance for treatment. The pre- and post-operative dental casts were digitized with SmartOptics Activity 880 scanner,and the three-dimensional overlapping models were obtained by reverse engineering software,Geomagic Studio 2012,then the three-dimensional movements of the upper and lower incisors were analyzed using Imageware 13.2 software. The overbite and overjet were analyzed using the same methods. Measurement with copper wire was used to analyze the upper and lower arch length. Space analysis was the result by the sum of crown width minus the arch length. The crown width of unerupted permanent teeth was according to X-ray method to predict. The SPSS 17.0 software was used to analyze the pre- and post-operative measurements of the same child. The normality test of the measured data showed that it conformed to the normal distribution. Therefore,the t test and double side test were used,and the significance level was 0.05. The course of treatment was (5.6±2.7) months. During orthodontic treatment, the upper incisors moved mainly labially (P<0.001) in three-dimensional displacement, and the lower incisors moved mainly the same direction (P=0.025). During the treatment of eruption guidance appliance,the average overbite decreased (1.01±0.9) mm (t=-3.531, P=0.006), and the difference was statistically significant. There was no statistically significant difference between the pre- and post-operative average overjet (t=0.771, P=0.460). The severity of crowding in upper arch decreased (1.9±0.99) mm (t=-6.042, P<0.001),and that in lower arch decreased (1.9±0.74) mm (t=-8.143, P<0.001), both of the differences were statistically significant. The anterior cross bite in mixed dentition could be corrected by eruption guidance appliance, and at the same time, the normal overjet and overbite were established, and the teeth were aligned.

Mediation modeling can explain the nature of the relation among three or more variables. In addition, it can be used to show how a variable mediates the relation between levels of intervention and outcome. The Sobel test, developed in 1990, provides a statistical method for determining the influence of a mediator on an intervention or outcome. Although interactive Web-based and stand-alone methods exist for computing the Sobel test, SPSS and SAS programs that automatically run the required regression analyses and computations increase the accessibility of mediation modeling to nursing researchers. To illustrate the utility of the Sobel test and to make this programming available to the Nursing Research audience in both SAS and SPSS. The history, logic, and technical aspects of mediation testing are introduced. The syntax files sobel.sps and sobel.sas, created to automate the computation of the regression analysis and test statistic, are available from the corresponding author. The reported programming allows the user to complete mediation testing with the user's own data in a single-step fashion. A technical manual included with the programming provides instruction on program use and interpretation of the output. Mediation modeling is a useful tool for describing the relation between three or more variables. Programming and manuals for using this model are made available.

Aim of the study was to assess the effect of different surface treatments on the shear bond strength (SBS) of the veneering ceramics to zirconia core. In a shear test the influence of grinding and sandblasting of the zirconia surface on bonding were assessed. Statistical analysis was performed using SPSS statistical package (version 17.0, SPSS Inc., Chicago, IL, USA) and Microsoft Office Excel 2003 (Microsoft, Seattle, WA, USA). There was a significant difference between the groups considering shear bond strength (SBS) values, i.e. ground and sandblasted samples had significantly higher SBS values than only ground samples (mean difference = -190.67; df = 10, t = -6.386, p < 0.001). The results of the present study indicate that ground and sandblasted cores are superior to ground cores, allowing significantly higher surface roughness and significantly higher shear bond strength between the core and the veneering material.

When multiple regression is used in explanation-oriented designs, it is very important to determine both the usefulness of the predictor variables and their relative importance. Standardized regression coefficients are routinely provided by commercial programs. However, they generally function rather poorly as indicators of relative importance, especially in the presence of substantially correlated predictors. We provide two user-friendly SPSS programs that implement currently recommended techniques and recent developments for assessing the relevance of the predictors. The programs also allow the user to take into account the effects of measurement error. The first program, MIMR-Corr.sps, uses a correlation matrix as input, whereas the second program, MIMR-Raw.sps, uses the raw data and computes bootstrap confidence intervals of different statistics. The SPSS syntax, a short manual, and data files related to this article are available as supplemental materials from http://brm.psychonomic-journals.org/content/supplemental.

Egypt has the highest prevalence of Hepatitis C Virus (HCV) in the world, estimated nationally at 14.7%. HCV treatment consumes 20% ($80 million) of Egypt's annual health budget. Outcomes of cirrhotic patients admitted to the ICU may, in fact, largely depend on differences in the state of the disease, criteria and indications for admission, resource utilization, and intensity of treatment. The aim of the present study was to evaluate the efficacy of liver specific scoring models in predicting the outcome of critically ill cirrhotic patients in the ICU as it may help in prioritization of high risk patients and preservation of ICU resources. Over one year, a total of 777 patients with End Stage Liver Disease (ESLD) due to HCV infection were included in this retrospective non-randomized human study. All statistical analyses were performed by the statistical software SPSS version 22.0 (SPSS, Chicago, IL, USA). Child Turcotte Pugh (CTP) score, MELD score, MELD-Na, MESO, iMELD, Refit MELD and Refit MELD-Na were calculated on ICU admission. ICU admission was mainly due to Gastrointestinal (GI) bleeding and Hepatic Encephalopathy (HE). Overall mortality was 27%. Age and sex showed no statistical difference between survivors and non survivors. Significantly higher mean values were observed for all models among individuals who died compared to survivors. MELD-Na was the most specific compared to the other scores. MELD-Na was highly predictive of mortality at an optimized cut-off value of 20.4 (AURC=0.789±0.03-CI 95%=0.711-0.865) while original MELD was highly predictive of mortality at an optimized cut-off value of 17.4 (AURC=0.678±0.01-CI 95%=0.613-0.682) denoting the importance of adding serum sodium to the original MELD. INR, serum creatinine, bilirubin, white blood cells count and hyponatremia were significantly higher in non survivors compared to survivors, while hypoalbuminemia showed no statistical difference. The advent of Hepatorenal Syndrome (HRS) and Spontaneous Bacterial Peritonitis (SBP) carried worse prognosis. Hyponatremia and number of transfused blood bags were additional independent predictors of mortality. In cirrhosis of liver, due to HCV infection, patients who died during their ICU stay displayed significantly higher values on all prognostic scores at admission. The addition of sodium to MELD score greatly improves the predictive accuracy of mortality. MELD-Na showed the highest predictive value of all scores.

Aims and Objective: The aim of the study was to evaluate the reliability of cone beam computed tomography (CBCT) obtained image over plaster model for the assessment of mixed dentition analysis. Materials and Methods: Thirty CBCT-derived images and thirty plaster models were derived from the dental archives, and Moyer's and Tanaka-Johnston analyses were performed. The data obtained were interpreted and analyzed statistically using SPSS 10.0/PC (SPSS Inc., Chicago, IL, USA). Descriptive and analytical analysis along with Student's t-test was performed to qualitatively evaluate the data and P < 0.05 was considered statistically significant. Results: Statistically, significant results were obtained on data comparison between CBCT-derived images and plaster model; the mean for Moyer's analysis in the left and right lower arch for CBCT and plaster model was 21.2 mm, 21.1 mm and 22.5 mm, 22.5 mm, respectively. Conclusion: CBCT-derived images were less reliable as compared to data obtained directly from plaster model for mixed dentition analysis. PMID:28852639

To study the reliability of Purkinje image analysis for assessment of intraocular lens tilt and decentration in pseudophakic eyes. The study comprised 64 eyes of 39 patients. All eyes underwent phacoemulsification with intraocular lens implanted in the capsular bag. Lens decentration and tilt were measured multiple times by an infrared Purkinjemeter. A total of 396 measurements were performed 1 week and 1 month postoperatively. Lens tilt (Tx, Ty) and decentration (Dx, Dy) in horizontal and vertical directions, respectively, were calculated by dedicated software based on regression analysis for each measurement using only four images, and afterward, the data were averaged (mean values, MV) for repeated sequence of measurements. New software was designed by us for recalculating lens misalignment parameters offline, using a complete set of Purkinje images obtained through the repeated measurements (9 to 15 Purkinje images) (recalculated values, MV'). MV and MV' were compared using SPSS statistical software package. MV and MV' were found to be highly correlated for the Tx and Ty parameters (R2 > 0.9; p < 0.001), moderately correlated for the Dx parameter (R2 > 0.7; p < 0.001), and weakly correlated for the Dy parameter (R2 = 0.23; p < 0.05). Reliability was high (Cronbach α > 0.9) for all measured parameters. Standard deviation values were 0.86 ± 0.69 degrees, 0.72 ± 0.65 degrees, 0.04 ± 0.05 mm, and 0.23 ± 0.34 mm for Tx, Ty, Dx, and Dy, respectively. The Purkinjemeter demonstrated high reliability and reproducibility for lens misalignment parameters. To further improve reliability, we recommend capturing at least six Purkinje images instead of three.

The purpose of this study was to present a new periapical and endodontic status scale (PESS) that is based on the complex periapical index (COPI), which was designed for the identification and classification of periapical bone lesions in cases of apical periodontitis, and the endodontically treated tooth index, which was designed for endodontic treatment quality evaluation by means of cone-beam computed tomographic (CBCT) analysis. Periapical and endodontic status parameters were selected from the already known indexes and scientific literature for radiologic evaluation. Radiographic images (CBCT imaging, digital orthopantomography [DOR], and digital periapical radiography) from 55 patients were analyzed. All parameters were evaluated on CBCT, DOR, and digital periapical radiographic images by 2 external observers. The statistical analysis was performed with software SPSS version 19.0 (SPSS Inc, Chicago, IL). Chi-square tests were used to compare frequencies of qualitative variables. The level of significance was set at P ≤ .05. Overall intraobserver and interobserver agreements were very good and good, respectively. CBCT analysis found more lesions and lesions of bigger dimension (P < .001). CBCT imaging was also superior in locating lesions in the apical part on the side compared with DOR and in the diagnosis of cortical bone destruction compared with both methods (P < .001). Through CBCT analysis, more root canals and more canals associated with lesions were found. The most informative and reproducible periapical and endodontic status parameters were selected, and a new PESS was proposed. The classification proposed in the present study seems to be reproducible and objective and adds helpful information with respect to the existing indexes. Future studies need to be conducted to validate PESS. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

Despite the fact that Ethiopia has scale up antiretroviral treatment (ART) program, little is known about the patient satisfaction with ART monitoring laboratory services in health facilities. We therefore aimed to assess patient satisfaction with laboratory services at ART clinics in public hospitals. Hospital based, descriptive cross sectional study was conducted from October to November 2010 among clients attending in nine public hospitals ART clinics in Addis Ababa Ethiopia. Patients' satisfaction towards laboratory services was assessed using exit interview structured questionnaire. Data were coded and entered using EPI info 2002 (Centers for Disease Control and Prevention Atlanta, GA) and analyzed using SPSS version 15 software (SPSS INC, Chicago, IL, USA). A total of 406 clients were involved in the study. Of these 255(62.8%) were females. The overall satisfaction rate for ART monitoring laboratory services was (85.5%). Patients were satisfied with measures taken by health care providers to keep confidentiality and ability of the person drawing blood to answer question (98.3% and 96.3% respectively). Moreover, the finding of this study revealed, statistical significant associations between the overall patients' satisfaction with waiting time to get blood drawing service, availability of ordered laboratory tests and waiting time to get laboratory result with (p < 0.05). Patients receiving blood drawing service less than 30 minute were 7.59 times (95% CI AOR: 3.92-14.70) to be more satisfied with ART monitoring laboratory services compared to those who underwent for more than 30 minutes. Overall, the satisfaction survey showed, most respondents were satisfied with ART monitoring laboratory services. However, factors such as improving accessibility and availability of latrines should be taken into consideration in order to improve the overall satisfaction.

The aim of this research was to explore quality of life (QOL) and acceptance of disability and social support of colostomy patients as well as the relationship between these factors. A descriptive, correlational study was conducted using four scales: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and European Organization for Research and Treatment of Cancer Colorectal Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-CR38) scales, the Acceptance of Disability Scale (ADS), and the Social Relational Quality Scale (SRQS). A convenience sample of 111 colostomy patients from four hospitals in Guangzhou who underwent colostomy operation at least one month prior to the study and who visited the stoma clinic or association from August 2011 to February 2012 was evaluated for inclusion in the study. All statistical analyses were performed using SPSS 17.0 software (SPSS Inc., Chicago, IL, USA). The patients' general health status was better than the reference level recommended by European Organization for Research and Treatment of Cancer, and the overall ADS score was average. The SRQS score was similar to that found in a Hong Kong study. The general health status and dimensions of QOL were significantly correlated with ADS and all of its dimensions (P < 0.05). The general health status and dimensions of QOL were also significantly correlated with SRQS and all of its dimensions (P < 0.05). QOL, acceptance of disability, and social relational quality of colostomy patients were closely related. Our results emphasize that patients should work to form rational values and close bonds with families and friends to achieve a better QOL.

Pain alleviation and improvement of functional status are the main objectives in the treatment of osteoarthritis. Artemisia absinthium (AA) was used traditionally in reducing pain and inflammation. The aim of the present study was to compare the effects of topical formulations of AA and piroxicam gel (PG) among patients with knee osteoarthritis. In total, 90 outpatients aged 30-70 years with the diagnosis of primary osteoarthritis in at least one knee were enrolled in a randomized double-blind clinical trial. The patients referred to the Rheumatology Clinic at Shahid Beheshti Hospital in Hamadan province during 2012-2013. The patients were randomly assigned into three groups, 30 patients per group, and respectively received AA ointment (AAO) 3%, AA liniment (AAL) 3%, and PG; three times daily (TID) for 4 weeks. The patients were visited at baseline, week 4, and week 6. The effectiveness criteria were pain severity which was assessed with a 10-point visual analog scale (VAS), the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) for total pain score (WTPS), total physical function score (WTPFS), and total stiffness score (WTSS). Repeated measure ANOVA, paired t test and post hoc were used to compare variables. Statistical analysis was performed using the SPSS software, version 13.0 (SPSS Inc., Chicago, Illinois). All groups had similar patient demographics. The administration of PG significantly improved all tested criteria with no recurrence after discontinuing the treatment protocol. AAO alleviated all tested factors except for WTSS. Alleviation was comparable to PG. AAL only reduced pain factors (VAS, WTPS) in week 4 with recurrence in week 6. Administration of Artemisia ointment may have beneficial effects in the treatment of osteoarthritis. Trial Registration Number: IRCT201202123109N3.

The evaluation of coronary stents by computed tomography (CT) remains difficult. We assessed the imaging performance of a high-definition CT scanner (HDCT) by comparing with a conventional 64-row standard-definition CT (SDCT). One hundred thirty-eight consecutive stented patients underwent coronary CT angiography, among whom 66 patients were examined by HDCT, and 72 patients by SDCT (LightSpeed VCT XT; GE Healthcare, Waukesha, Wis). The image quality score, the inner stent diameter (ISD), and the radiation dose were analyzed. All data were statistically tested by SPSS 13.0 software (SPSS Inc, Chicago, Ill). In 72 patients examined using SDCT, 135 stents were detected; in 66 patients examined using HDCT, 119 stents were detected. The image quality score on HDCT was significantly better than that on SDCT (1.4 [SD, 0.7] vs 1.9 [SD, 0.8]). The ISD on HDCT was significantly higher than that on SDCT (1.8 [SD, 0.5] vs 1.6 [SD, 0.4]). There was no significant difference of either image quality score or ISD between the HDCT and SDCT groups in stents with 2.5-mm diameter. Images on HDCT showed significantly better image quality score and larger ISD than images on SDCT in 2.75-, 3-, and 3.5-mm stents. For patients examined by retrospective electrocardiogram-gated technique, the radiation dose on HDCT was significantly lower than that on SDCT (11.3 [SD, 2.9] vs 15.1 [SD, 3.8] mSv). High-definition CT scanner offered improved image quality and measurement accuracy for imaging coronary stents compared with conventional SDCT, providing higher spatial resolution and lower dose for evaluating coronary stents with 2.75- to 3.5-mm diameter.

This study aims to evaluate the effectiveness of implementing a stroke protocol (SP) in improving door-to-needle time (DTNT) and door-to-computed tomography (DTCT) time from 2010 to 2014. Published data from the Get With The Guidelines-Stroke (GWTGS) participating hospitals showed that median DTNT = 75 minutes with 26.6% of the patients achieving the recommended DTNT of 60 minutes or less. Implementation of an SP, which specifies the role of nurses, physicians, and technicians during acute stroke evaluation, can improve DTNT. This longitudinal quality assurance study was designed to compare the DTNT and the DTCT time pre- and post implementation of an SP in our hospital. Patients' data before (2009-2010) and after (2010-2014) the implementation of an SP were collected each year during the same 6-month period and compared using statistical software SPSS 20.0 for Windows (SPSS Inc., Chicago, IL). Although our DTNT did not significantly improve over the years, the median DTNT (59 minutes) was much less than the reported 75 minutes of GWTGS hospitals. Our DTCT time diminished from 20.6 minutes in 2009 to 15.9 minutes in 2014. The percentage of patients with a DTNT of 1 hour or less did not differ among all years (P = .296) and was 55.8%. Our study suggests that our performance in evaluating acute ischemic stroke patients within the American Heart Association/American Stroke Association suggested time window is reachable for prolonged periods of time. Continuous monitoring and education of all players involved are crucial to ensure best possible outcomes in the timely administration of intravenous tissue plasminogen activator.

The low rate of consent by next of kin of donor-eligible patients is a major limiting factor in organ transplant. Educating health care professionals about their role may lead to measurable improvements in the process. Our aim was to describe the developmental steps of a communication skills training program for health care professionals using standardized patients and to evaluate the results. We developed a rubric and 5 cases for standardized family interviews. The 20 participants interviewed standardized families at the beginning and at the end of the training course, with interviews followed by debriefing sessions. Participants also provided feedback before and after the course. The performance of each participant was assessed by his or her peers using the rubric. We calculated the generalizability coefficient to measure the reliability of the rubric and used the Wilcoxon signed rank test to compare achievement among participants. Statistical analyses were performed with SPSS software (SPSS: An IBM Company, version 17.0, IBM Corporation, Armonk, NY, USA). All participants received higher scores in their second interview, including novice participants who expressed great discomfort during their first interview. The participants rated the scenarios and the standardized patients as very representative of real-life situations, with feedback forms showing that the interviews, the video recording sessions, and the debriefing sessions contributed to their learning. Our program was designed to meet the current expectations and implications in the field of donor consent from next of kin. Results showed that our training program developed using standardized patient methodology was effective in obtaining the communication skills needed for family interviews during the consent process. The rubric developed during the study was a valid and reliable assessment tool that could be used in further educational activities. The participants showed significant improvements in communication skills.

Advances in all-ceramic systems have established predictable means of providing metal-free aesthetic and biocompatible materials. These materials must have sufficient strength to be a practical treatment alternative for the fabrication of crowns and fixed partial dentures. The aim of this study was to compare the biaxial flexural strength of three core ceramic materials. Three groups of 10 disc-shaped specimens (16 mm diameter x 1.2 mm thickness - in accordance with ISO-6872, 1995) were made from the following ceramic materials: Turkom-Cera Fused Alumina [(Turkom-Ceramic (M) Sdn Bhd, Puchong, Selangor, Malaysia)], In-Ceram (Vita Zahnfabrik, Bad Säckingen, Baden-Württemberg, Germany) and Vitadur-N (Vita Zahnfabrik, Bad Säckingen, Baden-Württemberg, Germany), which were sintered according to the manufacturer's recommendations. The specimens were subjected to biaxial flexural strength test in an universal testing machine at a crosshead speed of 0.5 mm/min. The definitive fracture load was recorded for each specimen and the biaxial flexural strength was calculated from an equation in accordance with ISO-6872. The mean biaxial flexural strength values were: Turkom-Cera: 506.8 ± 87.01 MPa, In-Ceram: 347.4 ± 28.83 MPa and Vitadur-N: 128.7 ± 12.72 MPa. The results were analyzed by the Levene's test and Dunnett's T3 post-hoc test (SPSS software V11.5.0 for Windows, SPSS, Chicago, IL, USA ) at a preset significance level of 5% because of unequal group variances (P<0.001). There was statistically significant difference between the three core ceramics (P<0.05). Turkom-Cera showed the highest biaxial flexural strength, followed by In-Ceram and Vitadur-N. Turkom-Cera core had significantly higher flexural strength than In-Ceram and Vitadur-N ceramic core materials.

Communication among healthcare providers continues to change, and 90% of healthcare providers are now carrying cellular phones. Compared with pagers, the rate and amount of information immediately available via cellular phones are far superior. Wireless devices such as smartphones are ideal in acute trauma settings as they can transfer patient information quickly in a coordinate manner to all the team members responsible for patient care. A questionnaire survey was distributed among all the trauma surgeons, surgery residents, and nurse practitioners who were a part of the trauma surgery team at a Level 1 trauma center. Answers to each question were recorded on a 5-point Likert scale. The completed survey questionnaires were analyzed using Statistical Package for Social Sciences software (SPSS version 17; SPSS, Inc., Chicago, IL). The respondents had an overall positive experience with the usage of the third-generation (3G) smartphones, with 94% of respondents in favor of having wireless means of communication at a Level 1 trauma center. Of respondents, 78% found the device very user friendly, 98% stated that use of smartphones had improved the speed and quality of communication, 96% indicated that 3G smartphones were a useful teaching tool, 90% of the individuals felt there was improvement in the physician's response time to both routine and critical patients, and 88% of respondents were aware of the rules and regulations of the Health Insurance Portability and Accountability Act. Smartphones in an acute trauma setting are easy to use and improve the means of communication among the team members by providing accurate and reliable information in real time. Smartphones are effective in patient follow-up and as a teaching tool. Strict rules need to be used to govern the use of smartphones to secure the safety and secrecy of patient information.

The British Dietetic Association and the International Confederation of Dietetic Associations are developing an international model for dietetics practice as an aid in providing evidence-based practice. In the USA, undergraduate programmes are mandated by the Academy of Nutrition and Dietetics (formerly the American Dietetic Association) to incorporate the nutrition care process (NCP) into the curriculum so that students can use the process during their dietetic internship and later practice. The present study aimed to assess interns' readiness in the NCP prior to beginning a dietetic internship. Before starting the internship, the 40 interns in the 2009-2010 class of a university-based internship were sent an e-mail requesting they complete an online survey. Questions inquired about their NCP background with respect to: academic preparation, work or volunteer experiences, knowledge and confidence in ability to apply the NCP. Survey results were analysed with SPSS statistical software (SPSS Inc., Chicago, IL, USA). The 39 interns completing the survey indicated they had prior exposure to the NCP. All but one reported that their academic coursework covered the NCP. Approximately half of the interns worked or volunteered in settings that used the NCP. Overall, students correctly answered most of the questions assessing their basic knowledge in the NCP. Thirty-seven of the 39 interns had some confidence or felt confident in their ability to apply the NCP during internship rotations. This distance internship attracts students from all over the USA, and so the findings of the present study shed light on current undergraduate preparation in the NCP. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

India is fast finding its place in the industrialized world and that is beginning to raise its environmental consciousness. The Delphi technique was used to prioritize specific needs and articulate a sustainable urban improvement strategy for the city of Mumbai (formerly Bombay). The Delphi technique is a means of achieving consensual validity among raters by providing them feedback regarding other raters' responses. Mumbai has several indigenous environmental groups that were tapped for activists and leaders; the study was conducted using ten environmentalists. In the initial phases the responses resulted in a range of possible program alternatives. The last two stages helped to seek out information that generated a consensus on the part of the respondent group. Statistical analysis methods included a hierarchical cluster analysis, mean, median, mode, and percent of agreement calculations using SPSS software. The face-to-face discussion in phase 4 clarified some issues and helped the group as a whole to outline the strategy for putting in place the essential elements of a framework to improve the quality of life in an urban environment.

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease of unknown etiology. Many cytokines have been found to be associated with RA pathogenesis and among them is macrophage migration inhibitory factor (MIF). The aim of this study was to determine whether MIF serum levels are associated with RA course, clinical activity, and clinical biomarkers of the disease. MIF levels were determined in serum samples of 54 RA patients and 78 healthy subjects (HS) by enzyme-linked immunosorbent assay (ELISA). Disease activity was evaluated using the DAS28 score. Patients were subgrouped according to disease activity and years of evolution of disease. Statistical analysis was carried out by SPSS 10.0 and GraphPad Prism 5 software. RA patients presented increased levels of MIF as compared to HS. MIF levels were raised on early stages of RA and tend to decrease according to years of evolution. Moreover, MIF levels positively correlated with rheumatoid factor in RA patients and with C reactive protein in all individuals studied. Our findings suggest that MIF plays a role in early stages of RA.

They had routine antenatal investigations, a 1 h 50-g oral glucose tolerance test and quantitative urine culture and sensitivity. The data collected were analysed using statistical software package SPSS v. 17. Prevalence of AB was 23 (8.6%). Escherichia coli was the commonest isolate (6, 26.1%), closely followed by Staphylococcus aureus (5, 21.7%). AB was commoner among patients aged 25-34 years, of low parity and higher education. Blood group B- rhesus-positive significantly predicts the likelihood of developing AB in pregnancy (adjusted OR: 0.36; 95% CI: 0.14-0.96). We conclude that blood group B-rhesus-positive in association with other patients' characteristics, such as age 25-34 years, low parity and higher education could form guidelines for a screening algorithm in our environment.

This study focused on the relationship between religion, religiosity/spirituality (R/S), and attitudes of a sample of South African male secondary school youth toward women's rights to legal abortion in different situations. We distributed 400 self-administered questionnaires assessing the main variables (attitudes toward reasons for abortion and R/S) to the target sample in six different secondary schools in KwaZulu-Natal, South Africa. The responses of a final sample of 327 learners were then analyzed using the Statistical Package for the Social Sciences (SPSS) software. The findings revealed that religion and R/S play a role in the youths' attitudes toward abortion. While the Hindu subsample indicated higher overall support across the different scenarios, the Muslim subsample reported greater disapproval than the other groups on 'Elective reasons' and in instances of 'Objection by significant others.' The Christian youth had the most negative attitudes to abortion for 'Traumatic reasons' and 'When women's health/life' was threatened. Across the sample, higher R/S levels were linked with more negative attitudes toward reasons for abortion.

To analyze the effect of porcelain dental restoration combined with labial surface root filling for the anterior teeth. One hundred cases with anterior teeth protrusion treated in our department from January 2010 to January 2014 underwent porcelain dental restoration combined with labial surface root filling. The measurements in cephalometric X-ray films before and after treatment were compared, and porcelain dental appearance and function were evaluated. The data was statistically analyzed with SPSS18.0 software package. After treatment, U1-SN, U1-X, U1-Y were significantly lower than before treatment (P<0.01). U1-L1 was significantly higher after treatment (P<0.01). The incidence of gingivitis after treatment decreased significantly (X(2)=16.2749,P=0.0000<0.01). The excellent rate of outline of porcelain teeth after treatment, correction of protruding anterior teeth, fitting with adjacent teeth and alleviation of deep overbite and deep cover was 96.00%, 95.00%, 98.00% and 91.00%, respectively. Porcelain dental restoration after root canal treatment can effectively improve anterior teeth protrusion and increase the aesthetic appearance, which is worthy of clinical application.

To assess the food intake of energy, macronutrients and micronutrients related to growth and development in individuals under 16 years of age living in a consolidated invasion settlement in Maceió, Alagoas. The assessment of food intake was carried out by the 24-hour recall method, using a food picture album. Nutritional composition of diets was analysed using the Virtual Nutri-1.0 software. The estimated prevalence of inadequate intake was based on the Dietary Reference (DRIs), adjusted to account for intra-individual variability. The Statistical Package for Social Science (SPSS) version 11.5 was used for data analysis. 5.6% of the subjects studied presented excessive energy intake and for 3.7% it was inadequate. The frequency of excessive energy intake was higher in the 1 to 3 year-old age group (p <0.05), which also showed higher rates of inadequate intake of vitamin A, vitamin E and zinc, and it was the only group in which average consumption of calcium was higher than the adequate intake. Data show that dietary patterns of the individuals studied need adjustments.

The investments and costs of infrastructure, communication, medical-related equipments, and software within the global healthcare ecosystem portray a rather significant increase. The emergence of this proliferation is then expected to grow. As a result, information and cross-system communication became challenging due to the detached independent systems and subsystems which are not connected. The overall model fit expending over a sample size of 320 were tested with structural equation modelling (SEM) using AMOS 20.0 as the modelling tool. SPSS 20.0 is used to analyse the descriptive statistics and dimension reliability. Results of the study show that system utilisation and system impact dimension influences the overall level of services of the healthcare providers. In addition to that, the findings also suggest that systems integration and security plays a pivotal role for IT resources in healthcare organisations. Through this study, a basis for investigation on the need to improvise the Malaysian healthcare ecosystem and the introduction of a cloud computing platform to host the national healthcare information exchange has been successfully established.

To compare the shear bond strength (SBS) of rebonded orthodontic metal brackets with different resin removal methods. Forty extracted premolars were chosen as samples and divided into 4 experimental groups. The teeth were bonded with brackets. The brackets from 3 groups were debonded while adhesive remnants were removed from bracket bases by methods of grinding, sandblasting, and direct flaming, respectively and then rebonded. The SBS values of all rebonded brackets were determined after pH cycling experiment for 30 days. Some rebonded bracket bases were selected and observed under scanning electron microscope (SEM). The data was analyzed by one-way ANOVA test using SPSS 13.0 software package. Statistical analysis revealed a significant difference of SBS values among the 4 experimental groups (P<0.05). The SBS values of the group by direct flaming was significantly lower compared to the other groups (P<0.05). There was no significant difference of SBS values among the other groups. The rebonded brackets after resin removal by grinding and sandblasting have a similar SBS compared to the initial brackets adhesive.

Suicidal ideation and attempts account for a significant number of Emergency Department visits and represent a major public and mental health problem. Suicide and suicide attempts are a major cause of death and morbidity worldwide. 111 suicide attempters (81 F (73%), 30 M (27%)) were consequently recruited in the Emergency Department of the Santa Maria della Misericordia, Perugia, Italy between June 2011 and June 2012. Patients were assessed and demographic and clinical data were collected in clinical records. Data analysis was conducted using SPSS software. Chi-square test and logistic regression were used as appropriate. A p-value <0.05 was considered statistically significant. Females attempt suicide 3 times more frequently than males and generally use a non-violent suicide attempt method. In our sample unmarried status is the most represented and the most common diagnosis is major depressive disorder, followed by borderline personality disorder. Suicide attempts are more frequent in January. It is of crucial importance to conduct a suicide risk assessment when subjects are admitted to an ED given that the strongest known predictor for future suicide is attempted suicide.

Creating a calm and stress-free environment affects education significantly. The effects of the emergency department overcrowding (EDO) on the training of emergency medicine residents (EMR) is a highly debated subject. Therefore, this study aimed to evaluate the effect of EDO on efficiency of EMR's education. In this cross-sectional study, the effects of overcrowding on EMR's education in the resuscitation room and acute care unit. Data collection was done using a questionnaire, which was filled out by the second year EMRs. The crowding level was calculated based on the national emergency department overcrowding scale (NEDOCS). The relationship between the two studied variables was evaluated using independent sample t-test and SPSS 21 statistical software. 130 questionnaires were filled out during 61 shifts. 47 (77.05%) shifts were overcrowded. The attend's ability to teach was not affected by overcrowding in the resuscitation room (p=0.008). The similar results were seen regarding the attend's training ability in the acute care unit. It seems that the emergency department overcrowding has no effect on the quality of education to the EMRs.

It is hard to differentiate the same species of wild growing mushrooms from different areas by macromorphological features. In this paper, Fourier transform infrared (FTIR) spectroscopy combined with principal component analysis was used to identify 58 samples of boletus bicolor from five different areas. Based on the fingerprint infrared spectrum of boletus bicolor samples, principal component analysis was conducted on 58 boletus bicolor spectra in the range of 1 350-750 cm(-1) using the statistical software SPSS 13.0. According to the result, the accumulated contributing ratio of the first three principal components accounts for 88.87%. They included almost all the information of samples. The two-dimensional projection plot using first and second principal component is a satisfactory clustering effect for the classification and discrimination of boletus bicolor. All boletus bicolor samples were divided into five groups with a classification accuracy of 98.3%. The study demonstrated that wild growing boletus bicolor at species level from different areas can be identified by FTIR spectra combined with principal components analysis.

To investigate the effect of sintering temperature on mechanical properties of dental zirconia toughened alumina (ZTA) ceramics prepared by gel-casting technique. The samples prepared by gel-casting were sintered at 1100, 1200, 1250, 1300 and 1400degrees centigrade for each group. The flexural strength, fracture toughness, Vickers hardness and brittleness index were obtained and microscopic morphology of each group was observed under scanning electron microscope (SEM). The data were statistically analyzed using SPSS 19.0 software package. The flexural strength, fracture toughness and Vickers hardness increased with the increasing sintering temperature during 1100~1400degrees centigrade. The lowest brittleness index (0.74±0.16) μm -1/2 was observed in group sintered at 1200degrees centigrade and the highest (2.76±0.14) μm -1/2 was at 1400degrees centigrade (P<0.05), while the flexural strength of these two groups was (46.89±3.24) MPa and (349.64±54.72) MPa, respectively. The ZTA dental ceramics exhibit good machinability with proper sintering temperature (1200degrees centigrade) and the strength meets the requirement of clinical application.

School is one of the places with the greatest prevalence of occurrence of traumatic dental injuries. The aim of this study was to assess the knowledge levels and attitudes of elementary school teachers towards dental trauma and its management. In this cross-sectional study, 281 elementary school teachers were selected through cluster sampling to answer the prepared questionnaire. The data obtained from the questionnaires were analyzed in SPSS software by using ANOVA test and t-test. p Value<0.05 was considered to be significant. The total knowledge and attitude were low and normal, respectively. No previous exposure to or close observation of a dental trauma was reported by 61.2% of teachers; while, 12.5% were trained on dental traumas first aid management. There was statistically significant relationship between the teacher's knowledge and previous first aids training. The knowledge of schoolteachers on emergency management of dental trauma is poor. Therefore, it seems to be helpful to consider the management of dental injuries especially avulsed teeth as a part of teachers' education.

This study describes the views of multidisciplinary teams on work-related empowerment in a transitional organization. The data were collected between September 2003 and January 2004 (n=115) and one year later (n=112) using a self-administered questionnaire consisting of verbal and behavioural items, empowerment outcomes, and factors promoting and impeding empowerment. The target population consisted of all members working in multidisciplinary teams at the Rheumatism Foundation Hospital in Finland. The response rate was 58% at both data collections. The data were analysed statistically using SPSS software. The multidisciplinary teams rated their work empowerment quite highly. The number of empowerment promoting factors was lowest for the category of future orientedness, consisting of continuity of work, opportunities for advancement, and access to information. The number of impeding factors was also highest for the same category of future orientedness, consisting here of organizational bureaucracy and hierarchy, authoritarian leadership, poor access to information, and short working periods. It is important not to underestimate the impacts of organizational changes: they have a direct effect on the work environment and may contribute to higher rates of dissatisfaction, burnout and absenteeism among health care workers.

Under the influence of traditional oriental culture, the lack of organ donation is especially serious in China and Japan. The aim of this study was to compare Chinese and Japanese college students' attitudes and analyze contributing factors toward deceased donation. An anonymous, self-administered questionnaire comprising 15 questions was distributed to approximately 400 college students at Liaoning University, China, and Kyushu University, Japan. Statistical analysis used SPSS software. Japanese students' attitude towards deceased organ donation was more favorable than that of Chinese students (43.6% versus 35.9%, P = .001). Several factors contributed to positive responses by students from both countries: family perspective on organ donation and transplantation; decision to donate to family members; prior blood donation; living liver or kidney donation; possibility of needing a transplant; and willingness to receive a deceased or a living donor organ. More efforts must emphasize awareness and up-to-date knowledge regarding organ donation among citizens and should be undertaken by the Chinese and Japanese governments. Copyright © 2013 Elsevier Inc.

Employee’s occupational stress and safety performance are highly related, which has been generally recognized by the researchers. We did this research to understand the status of the stress for construction workers, and explore the influence factors of pressure source with characteristics of construction industry. Based on the results of previous studies, we designed questionnaire to collect the influence factors on occupational stressors. The study selected workers from certain construction units at the grass-roots level as sample source. According to the results of the questionnaire, we redesigned the interview outline, and did the semi-structured interviews on workers randomly selected. Finally, we developed a scale which combined the characteristics of construction projects in China. Using SPSS software for factor analysis, reliability analysis, and descriptive statistical analysis, the results show that there are six factors affecting the workers’ occupational stress, including The Work Itself, Family-Work, Career Development, Organization Style, Interpersonal Relationship and Role Management Style. The work itself is the main sources of occupational stress. The results can be used by the construction company to provide guidance for workers to control and manage occupational stress.

Fatal high-voltage injuries present a problem which has not yet been studied sufficiently in the context of interaction between the human body and electricity, as a technical, anthropogenic and natural phenomenon. The forensic medicine records of 291 cases of death caused by high-voltage current for a 41-year-long period (1965-2006) were examined in retrospect. The descriptive statistical analyses were made using the SPSS 11.0 software. Death was found to result most commonly from contact between the deceased and elements of the power transmission and distribution grid: (41.24%), and from the action of lightning: (32.3%), the difference in their relative share being insignificant. Much more rarely, death was due to contact with construction and repair electrical devices: (7.56%), or with elements of the power transport railway infrastructure: (6.87%). Death resulting from contact with agricultural electrical devices was only occasional: (0.68%). The victims' average age was 36.19 years. Our analysis indicates that the relative share (43.98%) of the victims is the highest in the age period between 25 and 44. The ratio between women and men is 1:21.38.

The process of medical education depends on several issues such as training materials, students, professors, educational fields, and the applied technologies. The current study aimed at comparing the impacts of e-learning and lecture-based learning of mild induced hypothermia (MIH) after cardiac arrest on the increase of knowledge among emergency medicine residents. In a pre- and post-intervention study, MIH after cardiac arrest was taught to 44 emergency medicine residents. Residents were randomly divided into 2 groups. The first group included 21 participants (lecture-based learning) and the second had 23 participants (e-learning). A 19-item questionnaire with approved validity and reliability was employed as the pretest and posttest. Then, data were analyzed with SPSS software version 17.0. There was no statistically significant difference in terms of the learning method between the test scores of the 2 groups (P = 0.977). E-learning and lecture-based learning methods was effective in augmentation of residents of emergency medicine knowledge about MIH after cardiac arrest; nevertheless, there was no significant difference between these mentioned methods.

Colorectal cancer (CRC) is among the most common and fatal forms of solid tumors worldwide and more than two thirds of CRC and adenomas patients have APC gene mutations. APC is a key regulator in the Wnt/β-catenin signaling pathway but its roles in CRC remains to be elucidated. In this study, we compared APC genes between CRC patients and controls to determine possible associations of nucleotide changes in the APC gene with the pathways involved in CRC pathogenesis. All participants received physical and enteroscopic examinations. The APC gene was sequenced for 300 Chinese Han CRC patients and 411 normal controls, and the expression levels of genes in the signaling pathway were analyzed using Western Blotting. Statistical analyses were conducted using SPSS (version 19.0) software. We found that rs11954856 in the APC gene was associated with colorectal cancer and could increase the expression levels of APC , β-catenin , TCF7L1 , TCF7L2 and LEF1 genes in the pathway in the CRC patients, demonstrating the involvement of APC in the pathological processes leading to CRC.

Melasma is one of the most frequently acquired hyperpigmentation disorders clinically characterized by symmetrical brown patches on sun-exposed areas. To date, few studies have been conducted about the relationship between thyroid autoimmun-ity and melasma. To evaluate the thyroid dysfunction and autoimmunity in nonpregnant women with melasma. A total of 70 women with melasma and 70 age-matched healthy women with no history of melasma were enrolled in the study. We studied the thyroid hormone profile in both groups. The statistical analysis was performed using SPSS software. Patients with melasma had 18.5% frequency of thyroid disorders, and 15.7% had positive anti-TPO, while subjects from the control group had a 4.3% frequency of thyroid abnormalities, and only 5.7% had positive anti-TPO. There was a significantly higher prevalence of thyroid dysfunction in women with melasma compared with control group (P = 0.008). This study suggests that there is a relationship between thyroid autoimmunity and melasma. However, to make recommendations on screening for thyroid disease in patients with melasma, future research of good methodological quality is needed. © 2015 Wiley Periodicals, Inc.

Introduction: Successful root canal therapy depends on the complete elimination of microorganisms such as Entroccocus faecalis, which is impossible to achieve with the traditional methods. Lasers are recently introduced as a new method to solve the problem. The present study is planned and performed to examining the antibacterial effect of Er: YAG laser. Methods: Sixty extracted anterior primary teeth were prepared and sterilized. E. faecalis bacterium was cultured in canals. Samples were randomly divided into two groups. The first group was disinfected by NaOCl 5/25% and Er: YAG laser and the second group just by NaOCl 5/25%. Samples of canal contents were cultured and colony counts were calculated. The results were analyzed statistically by SPSS software and Mann Whitney test. Results: There was no significant difference between colony counts in both groups (P=0.142). But the number of colonies in the first group was lower than in the second group. Conclusion: Although, Er: YAG laser cannot completely eliminate E. faecalis bacterium, its simultaneous use with NaOCl decreases E. faecalis. PMID:29071021

condition of hypoxia caused by hypertrophy of adipose cells in obesity triggers macrophages recruitment and production of cytokines. Additionally, high consumption of saturated fatty acids (SFA) and high glycemic index meals may contribute to oxidative stress and chronic low-grade inflammation by increases NF-kB activation. Thus, the aim of the study was to analyze the contribution of the macronutrients intake in the metabolic and inflammatory profile, by levels of lipoproteins, insulin resistance, anti and pro inflammatory cytokines, in obese adolescents according the gender. sample was composed by 37 adolescents, both genders, identified as obese by body mass index (BMI). Body composition was assessed by Dual-energy X-ray absorptiometry (DEXA) and measures of intra-abdominal adiposity (IAAT) and subcutaneous adiposity tissue (SAT) were done by ultrasound. Biochemical analyses were done and the measurement of cytokines; fatty acids and insulin were performed by the technique of immunoassay ELISA. The estimation of macronutrients consumption was made by 3 day food register regarding food intake. Statistical significance was set at p-value < 5% and the statistical software SPSS version 17.0 (SPSS Inc, Chicago, IL) performed all analyses. BMI (p = 0.316), FM (p = 0.416), IAAT (p = 0.505) and SAT (p = 0.935) presented similarities between genders. Cytokines and metabolic variables values were similar between the groups. Only in the male group, metabolic variables and cytokines were significant correlated with the consumption of total lipids or its fractions. Was observed that insulin concentration had significant interaction with MUFA(g) (= -18.4; p = 0.004) and adiponectin with CHO(g) (= -58.2; p = 0.032) in the group male and female, respectively. macronutrients intake is associated with low-grade inflammation in obesity, by production of inflammatory cytokines and alteration of the lipid profile, especially male obese adolescents which seem to be more responsive of this consumption when compared with female obese adolescents.

This working paper discusses the statistical simulation part of a controlled software development experiment being conducted under the direction of the System Validation Methods Branch, Information Systems Division, NASA Langley Research Center. The experiment uses guidance and control software (GCS) aboard a fictitious planetary landing spacecraft: real-time control software operating on a transient mission. Software execution is simulated to study the statistical aspects of reliability and other failure characteristics of the software during development, testing, and random usage. Quantification of software reliability is a major goal. Various reliability concepts are discussed. Experiments are described for performing simulations and collecting appropriate simulated software performance and failure data. This data is then used to make statistical inferences about the quality of the software development and verification processes as well as inferences about the reliability of software versions and reliability growth under random testing and debugging.

Today, the challenges of quality improvement and customer focus as well as systems development are important and inevitable matters in higher education institutes. There are some highly competitive challenges among educational institutes, including accountability to social needs, increasing costs of education, diversity in educational methods and centers and their consequent increasing competition, and the need for adaptation of new information and knowledge to focus on students as the main customers. Hence, the purpose of this study was to determine the rate of costumer focus based on Isfahan University of Medical Sciences students' viewpoints and to suggest solutions to improve this rate. This was a cross-sectional study carried out in 2011. The statistical population included all the students of seven faculties of Isfahan University of Medical Sciences. According to statistical formulae, the sample size consisted of 384 subjects. Data collection tools included researcher-made questionnaire whose reliability was found to be 87% by Cronbach's alpha coefficient. Finally, using the SPSS statistical software and statistical methods of independent t-test and one-way analysis of variance (ANOVA), Likert scale based data were analyzed. The mean of overall score for customer focus (student-centered) of Isfahan University of Medical Sciences was 46.54. Finally, there was a relation between the mean of overall score for customer focus and gender, educational levels, and students' faculties. Researcher suggest more investigation between Medical University and others. It is a difference between medical sciences universities and others regarding the customer focus area, since students' gender must be considered as an effective factor in giving healthcare services quality. In order to improve the customer focus, it is essential to take facilities, field of study, faculties, and syllabus into consideration.

Perineal pain is a major morbidity in the first few days after delivery. This study aimed to investigate the effect of dry cupping therapy and acupressure at BL23 point on the intensity of postpartum perineal pain based on the short-form of McGill pain questionnaire (SMPQ). The present clinical trial was conducted on 150 subjects in 3 groups of 50 cases. After at least 4-8 hr of delivery, cupping therapy was performed for 15-20 min up to 3 times a week (once a day) and acupressure was performed for 15-20 min based on clockwise model. The short-form of McGill pain questionnaire was completed both before and after the intervention. The SPSS statistical software was used to analyze the data using repeated measures ANOVA. Besides, p<0.05 was considered statistically significant. In the cupping therapy group, mean of the perineal pain intensity reduced from 37.5±6.8 before the intervention to 11.1±6.1, 6.9±4.7, and 3.8±3.6 immediately, 24 hr, and 2 weeks after the intervention, respectively. The results of study showed that the differences between the intervention and control groups were statistically significant (p<0.01). Mean difference of the perineal pain intensity in the acupressure group reached from 35.6±8.1 before the intervention to 10.4±5.5 two weeks after the intervention, so the variation between intervention and control groups was statistically significant. The study findings showed that cupping therapy and acupressure reduced perineal pain. Therefore, they may be considered as effective treatments for reducing pain intensity of allowing delivery.

Leadership style of nurse managers plays a significant role in nurses' job satisfaction. However, there is limited literature in areas related to nurses' manager leadership style. The objective of this research was thus to investigate the relationship between leadership style of nurse managers and nurses' job satisfaction in Jimma University Specialized Hospital. The study was conducted at Jimma University Specialized Hospital from January to June 2012 and used a non-experimental correlation design. All full time, non-supervisory nurses with an experience of more than one year in nursing profession were participated in the study. The Multifactor Leadership Questionnaire and Minnesota Satisfaction Questionnaire were used to collect data. Data were entered and analyzed using SPSS version16.0 statistical software. The results were analyzed through descriptive statistics followed by the application of inferential statistics on the variables. Significance level was considered when p<0.05. A total of 175 copies of the questionnaires were returned out of 186 copies distributed to respondents. The result indicated that nurses can prefer transformational leadership style over transactional leadership style and had moderate-level intrinsic (M=2.72, SD=0.71) but low level of extrinsic job satisfaction (M=1.83, SD=0.68). Furthermore, from transactional leadership, only contingent reward was found to be statically significant and correlated with extrinsic (B=0.45, p<0.01) and intrinsic job satisfaction (B=0.32, p<0.05) while all five dimension of transformational leadership style were statistically significant and correlated with both intrinsic and extrinsic job satisfaction. Nurses tended to be more satisfied with the transformational leadership than transactional leadership style. Therefore, nurses' managers should use transformational leadership style in order to increase nurses' job satisfaction.

This study aimed to clinically quantify the apicoincisal height of the upper interproximal areas directly in patients' mouths compared to measurements on stone models. One hundred and fifty participants (75 females and 75 males, age range 20-45 years) were recruited for this study. A digital caliper was used to measure the anterior maxillary interproximal contact areas directly in patients' mouths and on stone models. The digital caliper accuracy was up to 0.01. The Statistical Package for Social Sciences software (SPSS, version 19.0, Chicago, Ill., USA) was used for statistical analysis. Statistical significance was based on probability values <0.05. The intraoral measurement of proximal contacts as well as the measurement on stone models showed that the dimensions of interproximal contacts on both sides of each tooth were significantly different (p < 0.001) and that the dimension of the mesial contact point was larger than that of the distal contact point of each tooth. The largest contact point was the one between the central incisors (direct intraoral measurement = 2.9-6.49 mm; model measurement = 3.31-6.91 mm). On the other hand, the contact point between the canine and first premolar was the smallest on both sides of the arch (0.63-2.52 mm intraorally, 0.98-2.88 mm on models). The intraoral measurement of contact points was more accurate than model measurements, and the differences were statistically significant (p < 0.001). The clinical evaluation of contact point dimensions using a digital caliper was more precise than measuring contact points on stone models; hence, it is a viable, quick and adequate method to be used routinely. © 2015 S.

Background As coffee consumption is increasing remarkably over the past decade, the health effects concerning the coffee drinking has gained a wide attention across the nation. However, there is not a true consensus regarding the effects of coffee on metabolic disease. Therefore, this study aims to examine the association between coffee intake and the risk of metabolic syndrome in Korean women Methods We used publicly accessible datasets collected through Korean National Health and Nutrition Examination Survey (KNHANES). Among 20,435 individuals from five consecutive years’ worth of data from 2007 to 2011, only 15,691 subjects qualified for statistical analysis upon applying the exclusion criteria. We carried out the statistical analysis utilizing SPSS Statistics version 13.0 (IBM Corp., Armonk, NY.) and STATA statistical software release 13.0 (STATA Corp., College Station, TX). Results We found that the frequency of coffee intake inversely correlates with the prevalence of metabolic syndrome in women. Upon adjusting for life-style factors, socioeconomic status, and nutritional profile, the subjects from the highest coffee consumption quartile exhibited 40% lower odds of suffering from metabolic syndrome compared to those in the control (OR = 0.75; 95% CI = 0.67–0.84; P for trend < 0.001). Also, we observed that age- and BMI-adjusted HOMA-IR decreased as the coffee consumption increased (P for trend < 0.001). Conclusion The findings of our study suggest that coffee consumption might be associated with reduction of metabolic syndrome in Korean women. To elucidate this cross-sectional association between coffee consumption and metabolic syndrome in women, cohort studies are warranted to confirm this relationship. PMID:27977716

Nigeria is one of the top three countries in Africa in terms of science research output and Nigerian urologists' biomedical research output contributes to this. Each year, urologists in Nigeria gather to present their recent research at the conference of the Nigerian Association of Urological Surgeons (NAUS). These abstracts are not thoroughly vetted as are full length manuscripts published in peer reviewed journals but the information they disseminate may affect clinical practice of attendees. This study aims to describe the characteristics of abstracts presented at the annual conferences of NAUS, the quality of the abstracts as determined by the subsequent publication of full length manuscripts in peer-review indexed journals and the factors that influence such successful publication. Abstracts presented at the 2007 to 2010 NAUS conferences were identified through conference abstracts books. Using a strict search protocol, publication in peer-reviewed journals was determined. The abstracts characteristics were analyzed and their quality judged by subsequent successful publishing of full length manuscripts. Statistical analysis was performed using SPSS 16.0 software to determine factors predictive of successful publication. Only 75 abstracts were presented at the NAUS 2007 to 2010 conferences; a quarter (24%) of the presented abstracts was subsequently published as full length manuscripts. Median time to publication was 15 months (range 2-40 months). Manuscripts whose result data were analyzed with 'beyond basic' statistics of frequencies and averages were more likely to be published than those with basic or no statistics. Quality of the abstracts and thus subsequent publication success is influenced by the use of 'beyond basic' statistics in analysis of the result data presented. There is a need for improvement in the quality of urological research from Nigeria.

In recent years, medical tourism market has been raised as one of the income-earning and competitive industries in the world and is considered as a modern field of advanced tourism. Therefore, a great number of countries are seeking to develop this type of tourism and one of the strategies for developing this industry is using the marketing mix elements. This study was a descriptive-analytic and cross sectional one. The research community included all the public and private hospitals of Shiraz among which, 7 public and 9 private hospitals were studied. The study data were collected through a researcher-made check list whose face and content validity was confirmed by the experts. Then, the data were entered into the SPSS statistical software. According to the objectives of the study, the descriptive results were presented in frequency tables and Chi-square test was used for data analysis. In addition, P<0.05 was considered as statistically significant. According to the results, both public and private hospitals of Shiraz were in the best condition regarding staff and physician mix and in the worst condition concerning promoting and facilities mixes. No significant difference was found between public and private hospitals regarding the mixes. From marketing mix elements view, paying more attention to media advertisements and providing more facilities can improve the status of the hospitals which, consequently, results in attracting more medical tourists and developing this industry in Shiraz.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) corresponds to a rare and acute life-threatening mucocutaneous reactions characterized by extensive necrosis and epidermal detachment. There are no efficacious pharmaceutical interventions proven through large clinical trials. We sought to study clinical cases admitted in our institution in order to determine which drugs and medical comorbidities or treatments impacted the mortality. In a retrospective study over 9 years we evaluated all patients presenting biopsy-proven SJS or TEN for age, gender, total body surface area involved, causing agents, SCORTEN score, blood transfusion, steroid administration, intubation, length of intensive care stay and death rate. Statistical analysis was done using SPSS statistical software. The highest incidence of SJS and TEN was in age group of 71-80 years. Of the 30 patients, 30% died from SJS/TEN, mainly due sepsis. For each subgroup SJS/TEN overlap had the highest mortality. The highest mortality was from antibiotic treatment as causing agent. Step-wise regression analysis identified mechanical ventilation requirement and age over 65 years as mortality high-risk factors. The most crucial interventions are discontinuation of the offending drug and prompt referral to a burn unit, which helps in early diagnosis and decrease mortality in these diseases. When SJS/TEN is caused by antibiotics suspicion of developing fatal sepsis should be high, independently of patients' medical condition.

Borago officinalis flower (borage) is a known sedative in herbal medicine; the aim of the present study was to evaluate the antinociceptive effect of borage hydroalcoholic extract in formalin test male rats. Fifty-six adult male albino Wistar rats were randomly divided into seven groups: Control groups of A (intact), B (saline), and C (Positive control) plus test groups of D, E, F, and G (n=8). The groups D, E, and F received 6.25, 12.5, and 25 mg/kg, Borago officinalis flower hydroalcholic extract before the test, respectively but group G received 25 mg/kg borage extract and aspirin before the test. A biphasic pain was induced by injection of formalin 1%. The obtained data were analyzed by SPSS software ver. 17 employing statistical tests of Kruskal-Wallis and Mann-Whitney. The results were expressed as mean±SD. Statistical differences were considered significant at P<0.05. The results revealed that the acute and chronic pain behavior score in test groups of D, E, F, and G significantly decreased compared to groups A and B, but this score did not show any difference compared to group C. Moreover, chronic pain behavior score in group G was significantly lower than all other groups. The results indicated that Borago officinalis hydroalcoholic extract affects the acute and chronic pain behavior response in formaline test male rats.

Background: Plasma rich in growth factors (PRGF) and freeze-dried bone allograft (FDBA) are shown to promote bone healing. This study was aimed to histologically and histomorphometrically investigate the effect of combined use of PRGF and FDBA on bone formation, and compare it to FDBA alone and control group. Materials and Methods: The distal roots of the lower premolars were extracted bilaterally in four female dogs. Sockets were randomly divided into FDBA + PRGF, FDBA, and control groups. Two dogs were sacrificed after 2 weeks and two dogs were sacrificed after 4 weeks. Sockets were assessed histologically and histomorphometrically. Data were analyzed by Kruskal–Wallis test followed by Mann–Whitney U-tests utilizing the SPSS software version 20. P < 0.05 was considered statistically significant. Results: While the difference in density of fibrous tissue in three groups was not statistically significant (P = 0.343), the bone density in grafted groups was significantly higher than the control group (P = 0.021). The least decrease in all socket dimensions was observed in the FDBA group. However, these differences were only significant in coronal portion at week 4. Regarding socket dimensions and bone density, the difference between FDBA and FDBA+PRGF groups was not significant in middle and apical portions. Conclusion: The superiority of PRGF+FDBA overFDBA in socket preservation cannot be concluded from this experiment. PMID:27857769

Bad breath has a significant impact on daily life of those who suffer from it. Oral malodor may rank only behind dental caries and periodontal disease as the cause of patient's visit to dentist. An aim of this study was to use a portable sulfide monitor as a motivational tool for encouraging the patients towards the better oral hygiene by correlating the plaque scores with sulfide monitor scores, and comparing the sulfide monitor scores before and after complete prophylaxis and 3 months after patient motivation. 30 patients with chronic periodontitis, having chief complaint of oral malodor participated in this study. At first visit, the plaque scores (P1) and sulfide monitor scores before (BCR1) and after complete oral prophylaxis (BCR2) were taken. Then the patients were motivated towards the better oral hygiene. After 3 months, plaque scores (P2) and sulfide monitor scores (BCR3) were recorded again. It was done using SPSS (student package software for statistical analysis). Paired sample test was performed. Statistically significant reduction in sulfide monitor scores was reported after the complete oral prophylaxis and 3 months after patient motivation. Plaque scores were significantly reduced after a period of 3 months. Plaque scores and breathchecker scores were positively correlated. An intensity of the oral malodor was positively correlated with the plaque scores. The portable sulfide monitor was efficacious in motivating the patients towards the better oral hygiene.

Major life changes are among factors that cause anxiety, and one of these changes is surgery. Emotional reactions to surgery have specific effects on the intensity and velocity as well as the process of physical disease. In addition, they can cause delay in patients recovery. This study is aimed at determining the relationship between religious beliefs and preoperative anxiety. This survey is a correlational study to assess the relationship between religious beliefs and preoperative anxiety of patients undergoing abdominal, orthopaedic, and gynaecologic surgery in educational hospitals. We used the convenience sampling method. The data collection instruments included a questionnaire containing the Spielberger State-Trait Anxiety Inventory (STAI), and another questionnaire formulated by the researcher with queries on religious beliefs and demographic characteristics as well as disease-related information. Analysis of the data was carried out with SPSS software using descriptive and inferential statistics. Results were arranged in three tables. The findings showed that almost all the subjects had high level of religiosity and moderate level of anxiety. In addition, there was an inverse relationship between religiosity and intensity of anxiety, though this was not statistically significant. The results of this study can be used as evidence for presenting religious counselling and spiritual interventions for individuals undergoing stress. Finally, based on the results of this study, the researcher suggested some recommendations for applying results and conducting further research.

The aim of this study was to compare the fracture of implant component behavior of external and internal type of implants to suggest directions for successful implant treatment. Data were collected from the clinical records of all patients who received WARANTEC implants at Seoul National University Dental Hospital from February 2002 to January 2014 for 12 years. Total number of implants was 1,289 and an average of 3.2 implants was installed per patient. Information about abutment connection type, implant locations, platform sizes was collected with presence of implant component fractures and their managements. SPSS statistics software (version 24.0, IBM) was used for the statistical analysis. Overall fracture was significantly more frequent in internal type. The most frequently fractured component was abutment in internal type implants, and screw fracture occurred most frequently in external type. Analyzing by fractured components, screw fracture was the most frequent in the maxillary anterior region and the most abutment fracture occurred in the maxillary posterior region and screw fractures occurred more frequently in NP (narrow platform) and abutment fractures occurred more frequently in RP (regular platform). In external type, screw fracture occurred most frequently, especially in the maxillary anterior region, and in internal type, abutment fracture occurred frequently in the posterior region. placement of an external type implant rather than an internal type is recommended for the posterior region where abutment fractures frequently occur.

To describe the management of sigmoid volvulus with reference to the type of surgical procedures performed and to determine the prognosis of sigmoid volvulus. A case series. Ghaem Hospital of Mashhad, University of Medical Sciences, Mashhad, Iran, from 1996 to 2008. A total of 944 cases of colon obstruction were reviewed. Demographic, laboratory and treatment results, mortality and complications were recorded. The data was analyzed using descriptive statistics as frequency and percentage for the qualitative variables and mean and standard deviation values for the quantitative variables. Also chisquare and Fisher's exact test were used for the association between the qualitative variables. SPSS statistical software (version 18) was used for the data analysis. In all patients except those with symptoms or signs of gangrenous bowel, a long rectal tube was inserted via the rectosigmoidoscope which was successful in 80 (36.87%) cases. Rectosigmoidoscopic detorsion was unsuccessful in 137 (63.13%) patients, who underwent an emergent laparotomy. The surgical procedures performed in these cases were resection and primary anastomosis in 40 (29.1%), Mikulicz procedure in 9 (6.6%), laparotomy detorsion in 37 (27.01%), Hartmann procedure in 47 (34.3%), mesosigmoidoplasty in 3 (2.19%) patients and total colectomy in one (0.73%) case. The overall mortality was 9.8% (22) patients. In sigmoid volvulus, the most important determinant of patient outcome is bowel viability. The initial treatment of sigmoid colon volvulus is sigmoidoscopy with rectal tube placement.

Nowadays, the most important problem of the educational system is the vast spread of school failure. Therefore, detection of the factors leading to or preventing students' academic achievement is of utmost importance. Family function is considered to be a critical component of academic success. This study aimed to investigate the relationship between family functioning and academic achievement in high school female students in Isfahan. This descriptive correlational study was conducted through random sampling among 237 female high school students in Isfahan during school year 2013-2014. Data were collected by participants' personal characteristics and Bloom family function questionnaires. To analyze the data, descriptive statistics (mean and standard deviation) and inferential statistics (Pearson correlation and linear regression analysis) were adopted and computed using SPSS software. The results showed a significant correlation between family function (except lack of independence) and students' academic achievement ( p < 0.05). Further, among family function dimensions, expressiveness ( β = 0.235, p < 0.001), family socialization ( β = 0.219, p = 0.001), and cohesion ( β = 0.211, p = 0.001) were more reliable predictors of academic achievement. The results of this study showed that students' academic achievement is highly correlated with the performance of their families. Therefore, to improve students' educational status in cultural and educational programs, which are specified for them, family function centered plans should be at the heart of attention.

Aloe vera is a medicinal herb used as an anti-inflammatory and sedative agent. The current study aimed to evaluate the effect of Aloe vera aqueous extract on morphine withdrawal symptoms in morphine-dependent female rats. The current research was performed on 40 female Wista-Albino rats which were made dependent on morphine using Houshyar protocol and were randomly divided into five groups (A, B, C, D, and E). Group A did not receive any agent in the period of handling but other groups (B, C, D and E) received 5, 10, 20 and 40 mg/kg of Aloe vera aqueous extract by gavage, three times daily for a week, respectively. Withdrawal symptoms, stool form, agitation, disparity, floppy eyelids, and body mass variations were checked for 10 days. The obtained data were analyzed using SPSS v.11 software, and Friedman, Kruskal-Wallis, and Mann-Whitney statistical tests. Statistical difference was considered significant (P < 0.05). The results of the present study showed that agitation, disparity, and floppy eyelids in group E were significantly higher than those of others groups; however, these symptoms in group C were significantly lower than those of the other groups. The results of the present study revealed that the Aloe vera aqueous extract had various effects on morphine withdrawal syndrome in morphine-dependent female rats .

Objective In recent years, psychological problems that are caused by working conditions, like burn out syndrome, are more commonly observed. In our study, we aimed to evaluate mobbing exposure, factors causing mobbing and precautions for mobbing in residency students who are educated in anaesthesiology and reanimation clinics in Turkey. Methods After obtaining consent from the ethics committee, we sent our questionnaires to the secretariats of the departments by postal mail. Completed questionnaires were collected in our department’s secretariat blindly and randomly mixed. One hundred and one participants were returned the questionnaires. Data was statistically analysed in SPSS 21.0 software programme. Results During residency programme, sated to have experienced mobbing one or more time. Interestingly, 5.9% participants complained of physical mobbing. Mobbing exposure was more common in females. The most serious new onset psychosomatic symptoms stated during residency were committing suicide (2%), addiction (16%), severe depression (18%), panic attack (8%), more accidents (7%) and tendency of violence (15%). In mobbing group there was statistically significant dissatisfaction rate. Conclusion In professions where mobbing is common, incidences of psychiatric diseases and suicide attempts are high are increased. Who are under risk for experiencing mobbing should be noticed carefully to ensure good judgement and problems should be inspected objectively in a detailed manner. Anesthesiology societies and other medical professional societies should establish mobbing committees. Thus, mobbing problems can be resolved and healthy career oppurtunities can be presented to residents. PMID:27909591

Multinomial logistic regression analysis was used to develop statistical model that can predict the probability of breast cancer in Southern Karnataka using the breast cancer occurrence data during 2007-2011. Independent socio-economic variables describing the breast cancer occurrence like age, education, occupation, parity, type of family, health insurance coverage, residential locality and socioeconomic status of each case was obtained. The models were developed as follows: i) Spatial visualization of the Urban- rural distribution of breast cancer cases that were obtained from the Bharat Hospital and Institute of Oncology. ii) Socio-economic risk factors describing the breast cancer occurrences were complied for each case. These data were then analysed using multinomial logistic regression analysis in a SPSS statistical software and relations between the occurrence of breast cancer across the socio-economic status and the influence of other socio-economic variables were evaluated and multinomial logistic regression models were constructed. iii) the model that best predicted the occurrence of breast cancer were identified. This multivariate logistic regression model has been entered into a geographic information system and maps showing the predicted probability of breast cancer occurrence in Southern Karnataka was created. This study demonstrates that Multinomial logistic regression is a valuable tool for developing models that predict the probability of breast cancer Occurrence in Southern Karnataka.

Background: Oral lichen planus (OLP) is a unique disorder affecting generally the older age group. Numerous studies have been done on various aspects of OLP such as pathogenesis, rate of malignant transformation, etc. However, very few studies are available with respect to clinical features especially association of hyperpigmentation and OLP. This study aims at studying the clinical aspects of OLP and study the association between hyperpigmentation and OLP in a south Indian population. Materials and Methods: A total of 58 patients with OLP who attended the outpatient department of our institution were included in the study and a complete history, followed by thorough intraoral examination was done. All the data were recorded and assessed for statistical analysis using SPSS software. Results: We found that the male to female ratio affected with OLP was 1:1 and the most common form of OLP that was seen was the reticular subtype. Also, buccal mucosa was the most common affected site and more than 60% patients had hyperpigmentation associated with the site affected by OLP. We found a statistically significant relation between the reticular type of OLP and the older age group (51–70 years) with hyperpigmentation. Conclusion: Although further studies are required to say anything conclusively, post-inflammatory changes occurring the mucosa due to OLP could be a cause for hyperpigmentation in the sites affected.

Hemodialysis (HD) is the readily available modality of renal replacement therapy in Nigeria today. The number of centers for HD continues to increase, but the majority is still located in the big cities and towns. A retrospective descriptive study in which records of patients on HD from 2004 to 2011 were reviewed. Data in respect of patients' sex, age, occupation and etiology of kidney disease were collected. Data were analyzed using Statistical Package for the Social Sciences statistical software version 16 (SPSS Inc, Chicago IL). A total of 1278 new patients were admitted for HD over the period of review; 60.9% (778) were males and 39.1% (500) females. Mean age of male patients was significantly higher than that of the females (P < 0.01). Those under the age of 40 years constituted 45.4% (580) of the study population, whereas 43.8% (560) were unskilled workers. Nearly 81.1% had CKD while 18.9% (241) had acute kidney injury (AKI). The most common cause of CKD and AKI were chronic glomerulonephritis (CGN) and sepsis respectively. This review showed a preponderance of males in the dialyzed population with males significantly older than the female patients. Patients aged ≤ 40 years and unskilled workers formed a large proportion of the population of HD treated patients. CGN and sepsis were the most common causes of CKD and AKI respectively.

The present study was designed to compare hand function in autistic children with history of upper extremity trauma with that of autistic children those who do not have history of trauma. The study group included total of 65 children diagnosed with autism spectrum disorder (ASD) and was divided into 2 groups: children with trauma history (Group I) and control group (Group II) (Group I: n=28; Group II: n=37). Hand function was evaluated with 9-Hole Peg Test and Jebsen Hand Function Test. Somatosensory function was evaluated using somatosensory subtests of Sensory Integration and Praxis Test. Results were analyzed with Student's t-test and Mann-Whitney U test using SPSS version 20 software. Hand function and somatosensory perception test scores were statistically significantly better in children without upper extremity trauma history (p<0.05). When association between hand function tests and upper extremity somatosensory perception tests was taken into account, statistically significant correlations were found between all parameters of hand function tests and Manual Form Perception and Localization of Tactile Stimuli Test results (p<0.05). Autistic children with upper extremity trauma history had poor somatosensory perception and hand function. It is important to raise awareness among emergency service staff and inform them about strong relationship between somatosensory perception, hand function, and upper extremity trauma in children with ASD in order to develop appropriate rehabilitation process and prevent further trauma.

Despite the important implication for women's health and reproduction, very few studies have focused on vaginal PH for menopausal diagnosis. Recent studies have suggested vaginal PH as a simple, noninvasive and inexpensive method for this purpose. The aim of this study is to compare serum FSH level with vaginal PH in menopause. This is a cross-sectional, descriptive study, conducted on 103 women (aged 31-95 yrs) with menopausal symptoms who were referred to the Menopausal Clinic at Ghaem Hospital during 2006. Vaginal pH was measured using pH meter strips and serum FSH levels were measured using immunoassay methods. The data was analyzed using SPSS software (version 11.5) and results were evaluated statistically by the Chi-square and Kappa tests. p≤0.05 was considered statistically significant. According to this study, in the absence of vaginal infection, the average vaginal pH in these 103 menopausal women was 5.33±0.53. If the menopausal hallmark was considered as vaginal pH>4.5, and serum FSH as ≥20 mIU/ml, then the sensitivity of vaginal pH for menopausal diagnosis was 97%. The mean of FSH levels in this population was 80.79 mIU/ml. Vaginal pH is a simple, accurate, and cost effective tool that can be suggested as a suitable alternative to serum FSH measurement for the diagnosis of menopause.

The present study validates a revised scale measuring individuals' level of the 'engagement in dietary behaviour' aspect of 'critical nutrition literacy' and describes how background factors affect this aspect of Norwegian tenth-grade students' nutrition literacy. Data were gathered electronically during a field trial of a standardised sample test in science. Test items and questionnaire constructs were distributed evenly across four electronic field-test booklets. Data management and analysis were performed using the RUMM2030 item analysis package and the IBM SPSS Statistics 20 statistical software package. Students responded on computers at school. Seven hundred and forty tenth-grade students at twenty-seven randomly sampled public schools were enrolled in the field-test study. The engagement in dietary behaviour scale and the self-efficacy in science scale were distributed to 178 of these students. The dietary behaviour scale and the self-efficacy in science scale came out as valid, reliable and well-targeted instruments usable for the construction of measurements. Girls and students with high self-efficacy reported higher engagement in dietary behaviour than other students. Socio-economic status and scientific literacy - measured as ability in science by applying an achievement test - did not correlate significantly different from zero with students' engagement in dietary behaviour.

This study assessed the factors affecting the choice of type of delivery with breast feeding in Iranian mothers. This Cross section descriptive analytic study was performed using a random sampling technique, using data from 400 pregnant women who attended the maternity centers in Borazjan and Kazerun in Iran in 2014. A questionnaire covering demographic characteristics, mode of delivery and postpartum conditions was completed for each mother. Descriptive analysis and Chi square test were used along with SPSS 23 software to statistically analyze the data and p-value less than 0.05 was considered for statistical significance. In this study, the rate of normal delivery and cesarean operation are considered equal. In the main factors influencing the choice of delivery, mothers' education level (p=0.028) and pregnancy status (p=0.041) showed a significant relationship. Although no significant association between child nutrition with the type of delivery was found, duration of breastfeeding with the type of delivery showed significant association (p=0.046). Although cesarean delivery in many cases is life-saving for mother and fetus; in addition to medical indications, parents with higher education and pregnancy status are also important factors in increasing the rate of cesarean section compared to vaginal delivery. Babies of mothers with normal delivery had a longer time of breastfeeding. Further studies in Iran are necessary, regarding the reasons for high cesarean section and their outcomes.

Psychological empowerment is really important and has remarkable effect on different organizational variables such as job satisfaction, organizational commitment, productivity, etc. So the aim of this study was to investigate the relationship between psychological empowerment and productivity of Librarians in Isfahan Medical University. This was correlational research. Data were collected through two questionnaires. Psychological empowerment questionnaire and the manpower productivity questionnaire of Gold. Smith Hersey which their content validity was confirmed by experts and their reliability was obtained by using Cronbach's Alpha coefficient, 0.89 and 0.9 respectively. Due to limited statistical population, did not used sampling and review was taken via census. So 76 number of librarians were evaluated. Information were reported on both descriptive and inferential statistics (correlation coefficient tests Pearson, Spearman, T-test, ANOVA), and analyzed by using the SPSS19 software. In our study, the trust between partners and efficacy with productivity had the highest correlation. Also there was a direct relationship between psychological empowerment and the productivity of labor (r =0.204). In other words, with rising of mean score of psychological empowerment, the mean score of efficiency increase too. The results showed that if development programs of librarian's psychological empowerment increase in order to their productivity, librarians carry out their duties with better sense. Also with using the capabilities of librarians, the development of creativity with happen and organizational productivity will increase.

Hydroelectrolytic disorders are common in clinical situations and may be harmful to the patient, especially those involving plasma sodium and potassium dosages. Among the possible methods for the dosages are flame photometry, ion-selective electrode (ISE) and colorimetric enzymatic method. We analyzed 175 samples in the three different methods cited from patients attending the laboratory of the University Hospital of the Federal University of Juiz de Fora. The values obtained were statistically treated using SPSS 19.0 software. The present study aims to evaluate the impact of the use of these different methods in the determination of plasma sodium and potassium. The averages obtained for sodium and potassium measurements by flame photometry were similar (P > .05) to the means obtained for the two electrolytes by ISE. The averages obtained by the colorimetric enzymatic method presented statistical difference in relation to ISE, both for sodium and potassium. In the correlation analysis, both flame photometry and colorimetric enzymatic showed a strong correlation with the ISE method for both dosages. At the first time in the same work sodium and potassium were analyzed by three different methods and the results allowed us to conclude that the methods showed a positive and strong correlation, and can be applied in the clinical routine. © 2018 Wiley Periodicals, Inc.

Data analysis in community health assessment (CHA) involves the collection, integration, and analysis of large numerical and spatial data sets in order to identify health priorities. Geographic Information Systems (GIS) enable for management and analysis using spatial data, but have limitations in performing analysis of numerical data because of its traditional database architecture.On-Line Analytical Processing (OLAP) is a multidimensional datawarehouse designed to facilitate querying of large numerical data. Coupling the spatial capabilities of GIS with the numerical analysis of OLAP, might enhance CHA data analysis. OLAP-GIS systems have been developed by university researchers and corporations, yet their potential for CHA data analysis is not well understood. To evaluate the potential of an OLAP-GIS decision support system for CHA problem solving, we compared OLAP-GIS to the standard information technology (IT) currently used by many public health professionals. SOVAT, an OLAP-GIS decision support system developed at the University of Pittsburgh, was compared against current IT for data analysis for CHA. For this study, current IT was considered the combined use of SPSS and GIS ("SPSS-GIS"). Graduate students, researchers, and faculty in the health sciences at the University of Pittsburgh were recruited. Each round consisted of: an instructional video of the system being evaluated, two practice tasks, five assessment tasks, and one post-study questionnaire. Objective and subjective measurement included: task completion time, success in answering the tasks, and system satisfaction. Thirteen individuals participated. Inferential statistics were analyzed using linear mixed model analysis. SOVAT was statistically significant (alpha = .01) from SPSS-GIS for satisfaction and time (p < .002). Descriptive results indicated that participants had greater success in answering the tasks when using SOVAT as compared to SPSS-GIS. Using SOVAT, tasks were completed more efficiently, with a higher rate of success, and with greater satisfaction, than the combined use of SPSS and GIS. The results from this study indicate a potential for OLAP-GIS decision support systems as a valuable tool for CHA data analysis.

Breast cancer is the most common cancer in women worldwide. In this study, we correlated the serum level of major histocompatibility complex class I-related chain A (sMICA) with expression and presentation of NKG2D receptors on NK cells among patients with breast cancer. Peripheral blood (PB) samples were collected from 49 healthy and 49 breast cancer patients before surgery and chemotherapy. The expression and presentation of NKG2D were assessed using qRT-PCR and flow cytometry, respectively. Furthermore, sMICA levels were determined using ELISA. In flow cytometry, whole blood samples were stained with anti-CD56/NKG2D/CD3 and the obtained results were analyzed using WinMDI software. In addition, SPSS software was used for statistical analysis of data. Significantly higher levels sMICA were detected in the sera of the majority of cancer patients in contrast to healthy volunteers (P < 0.001). The expression and presentation of NKG2D receptor were significantly lower than those in healthy persons, and with an inverse correlation to sMICA and positively correlated with tumor stage. Our study showed that sMICA may have an important role in diminishing the expression and presentation of NKG2D receptor in breast cancer patients and proposes the notion that sMICA can be a target candidate for treatment of breast cancer.

To analyze the reliability of the dento-maxillary models created by cone-beam CT and rapid prototyping (RP). Plaster models were obtained from 20 orthodontic patients who had been scanned by cone-beam CT and 3-D models were formed after the calculation and reconstruction of software. Then, computerized composite models (RP models) were produced by rapid prototyping technique. The crown widths, dental arch widths and dental arch lengths on each plaster model, 3-D model and RP model were measured, followed by statistical analysis with SPSS17.0 software package. For crown widths, dental arch lengths and crowding, there were significant differences(P<0.05) among the 3 models, but the dental arch widths were on the contrary. Measurements on 3-D models were significantly smaller than those on other two models(P<0.05). Compared with 3-D models, RP models had more numbers which were not significantly different from those on plaster models(P>0.05). The regression coefficient among three models were significantly different(P<0.01), ranging from 0.8 to 0.9. But between RP and plaster models was bigger than that between 3-D and plaster models. There is high consistency within 3 models, while some differences were accepted in clinic. Therefore, it is possible to substitute 3-D and RP models for plaster models in order to save storage space and improve efficiency.

An advanced and integrative information technology (IT)-landscape is needed for optimal support of future processes in health-care, including health services research. Most researches in the primary care sector are based on data collected for reimbursement. The aim of this study is to show the limits and options of secondary analysis based on data that was exported via the "Behandlungsdatentransfer" (treatment data transport) BDT-interface in the software systems of German general practitioners and afterwards prepared for further research in SPSS. From the middle of 2005 to the end of 2007 all 168 teaching practices of the Hannover Medical School (MHH) were invited to join the study. Finally routine data from 28 practices could be collected successfully. The data from 139 other practices which had been collected for the project "Health Care in Practice" ("Medizinische Versorgung in der Praxis" - MedViP) was also added to the pool. The process of data preparation included a complete cycle from data collection, merging the data in a relational database system, via statistics and analysis to publishing and generating a feedback report for the participating practices. During the whole study the limits and options of this method were systematically identified. Of the 168 practices, 68 (40.5%) were interested to participate. From 28 (16.7%) physicians the data could be exported from their software systems. In 15 (8.9%) cases no collection was possible due to technical and in 26 (15.5%) to administrative reasons. The method of data extraction varied, as the BDT-interface was differently implemented by the software companies. Together with the MedViP data, the database at the MHH now consists of 167 practices with 974 304 patients and 12 555 943 treatments. For 44.1% of the 11 497 899 prescription entries an anatomic therapeutic chemical (ATC) code could be applied, by matching the entries to the master data from the Scientific Institute of Local Health-Care Funds ("Wissenschaftliches Instituts der Ortskrankenkassen" - WIdO). Periodically consistent sets of SPSS files could successfully be created for further research and feedback reports for the participating practices were generated as portable document format (PDF) files. The BDT-interface seems quite out of date, but can still reveal interesting information, especially on data about medical treatments and findings. Much of the data is contained in fields based on free text, which makes analysis difficult. Coded information, like agents, as ATC, could partially be extracted from the data, which afterwards was easy to prepare for further research. Quality and content of the data depend mainly on the data enterer, the physicians and their practice staff. Future research could be improved by more classified and coded data, which would better be transported through an interface more advanced than BDT. Georg Thieme Verlag KG Stuttgart * New York.

Obesity and overweight have become increasingly a major public health problem across the world. This study aimed at exploring the effects of motivational interviewing on weight efficacy lifestyle among women with obesity and overweight. A single-blind randomized clinical trial study was conducted on 100 overweight and obese women who attended a nutrition clinic. The samples were selected based on the clinical records and assigned into two groups, namely motivational interviewing arm (50 samples) and nutrition education arm (50 samples). Data were collected using a standard validated questionnaire entitled "weight efficacy lifestyle". The intervention was designed according to five motivation sessions and four nutrition education programs, such that the participants of the nutrition education arm were also provided with the nutrition pamphlets related to weight control. Data were finally analyzed using the SPSS statistical software by performing the independent t-test, chi-square, LSD and repeated measures ANOVA tests. P<0.05 were considered statistically significant. The mean age of women was 39.9±9.1 and 36.3±8.9 years in the control and motivational interviewing arms, respectively. Compared with the control group, the score of the motivational interviewing group was statistically significant in terms of weight efficacy lifestyle P=0.0001) and all subscales including social pressure (P=0.0001), physical discomfort (P=0.005), food accessibility (P=0.0001), positive and entertainment activities (P=0.0001), as well as negative emotions (P=0.003). Motivational interviewing appeared to be effective in increasing weight efficacy lifestyle among women with overweight and obesity. IRCT2014051817736N1.

Background: The purpose of this study was to evaluate the effect of light-curing time on the shear bond strength (SBS) of two orthodontic color-change adhesives (CCAs). Materials and Methods: A total of 72 extracted premolars were randomly assigned into 6 groups of 12 teeth each. Subsequent to primer application, a metal bracket was bonded to the buccal surface using an orthodontic adhesive. Two CCAs (Greengloo and Transbond Plus) were tested and one conventional light-cured adhesive (Resilience) served as control. For each adhesive, the specimens were light-cured for two different times of 20 and 40 s. All the specimens underwent mechanical testing using a universal testing machine to measure the SBS. Adhesive remnant index (ARI) was used to assess the remnant adhesive material on the tooth surface. All statistical analyses were performed using SPSS software. The significance level for all statistical tests was set at P ≤ 0.05. Results: The SBSs of the tested groups were in the range of 14.05-31.25 MPa. Greengloo adhesive showed the highest SBS values when light-cured for 40 s, and Transbond Plus adhesive showed the lowest values when light-cured for 20 s. ARI scores of Transbond Plus adhesive were significantly higher than those of controls, while other differences in ARI values were not significant. Conclusion: Within the limitations of his study, decreasing the light-curing time from 40 to 20 s decreased the SBS of the tested adhesives; however, this decline in SBS was statistically significant only in Transbond Plus adhesive PMID:26005468

Introduction: Ensuring achievement of research experience by students is one of the most important goals of the thesis-conduction process and evaluation of student satisfaction with this process is one of the most imperative challenges herein. Aims: The aim of this study is to investigate the satisfaction of dental students passing the thesis educational course from the Isfahan Dental School. Settings and Design: Sixty-two dental students who had graduated in2011, from the Isfahan Dental School, participated in this descriptive cross-sectional study Materials and Methods: The postgraduate Research Experience Questionnaire (PREQ) was used for data collection. The questionnaire evaluated student satisfaction in seven domains: Thesis supervision, skill development, intellectual climate, infrastructure, thesis examination, goals and expectations, and overall satisfaction. Statistical Analysis Used: The data were analyzed on an SPSS software using descriptive and inferential statistics. Results: The mean score of satisfaction of the participants was 75 ± 12. On the basis of their scores, satisfaction in 3.2% of them was slow, in 33.9%was medium, in 61.3% was good and in 1.6% was high. The highest satisfaction was found to be in thesis supervision and the least was in the intellectual climate domain. There was no significant statistical difference between satisfaction and gender (P = 0.46). Conclusions: Considering the results, to increase student satisfaction for passing the thesis courses, it is necessary to improve the intellectual climate in dental schools and also increase the research budget for more financial support of students to carry out their projects.

Caries excavation is a noninvasive technique of caries removal with maximum preservation of healthy tooth structure. To compare the efficacy of three different caries excavation techniques in reducing the count of cariogenic flora. Sixty healthy primary molars were selected from 26 healthy children with occlusal carious lesions without pulpal involvement and divided into three groups in which caries excavation was done with the help of (1) carbide bur; (2) polymer bur using slow-speed handpiece; and (3) ultrasonic tip with ultrasonic machine. Samples were collected before and after caries excavation for microbiological analysis with the help of sterile sharp spoon excavator. Samples were inoculated on blood agar plate and incubated at 37°C for 48 hours. After bacterial cultivation, the bacterial count of Streptococcus mutans was obtained. All statistical analysis was performed using SPSS 13 statistical software version. Kruskal-Wallis analysis of variance, Wilcoxon matched pairs test, and Z test were performed to reveal the statistical significance. The decrease in bacterial count of S. mutans before and after caries excavation was significant (p < 0.001) in all the three groups. Carbide bur showed most efficient reduction in cariogenic flora, while ultrasonic tip showed almost comparable results, while polymer bur showed least reduction in cariogenic flora after caries excavation.

Introduction: Peripheral facial palsy (PFP) is commonly diagnosed in every emergency department. Despite being a benign condition in most cases, PFP causes loss in quality of life mostly due to facial dysmorphia. The etiology of PFP remains unknown in most cases, while medical opinion on epidemiology, risk factors and optimal treatment is not consensual. The aim of this study was to review the demographic characteristics of our patients and the medical care administered in our emergency department. Materials and Methods: Emergency episodes occurring in a 4-year period and codified as facial nerve pathology were analyzed. IBM SPSS software was used for statistical analysis. Results: In total, 582 emergency episodes were obtained. Due to inexpressive representation of other causes of PFP in our study, we focused our analyses on the 495 patients who were considered to have idiopathic PFP. There was equal distribution among genders, and all age ranges were affected. There were no clear epidemic phenomena. Hypertension was not a statistically significant risk factor for Bell's palsy. Most patients sought medical care in the early stages of the disease and complained of isolated facial weakness. Most patients had mild-to-moderate symptoms. Previous upper way infections (PUAI) were more frequent among children. There was a statistically significant difference regarding computed tomography (CT) scan requests among specialties. Conclusion: Epidemiologic findings were consistent with most literature on Bell's palsy. Drug therapy is widely used and follows current guidelines. The role of PUAI in the pediatric population must be investigated. Despite evidence of good medical practice, there was an excess of CT scans requested by physicians other than otorhinolaryngologists. PMID:29876329

Bibliotherapy is a supplement, simple, inexpensive and readily available method to treat the diseases that is performed with cooperation of librarians and psychologists or doctors. The aim of this study is the investigation of group bibliotherapy's effect on the self-esteem of the female students of Isfahan University of Medical Sciences Living in Dormitory in 2012. The present study is an interventional semi-experimental study with pre test and post test and control group. The statistical population of study consisted of 32 female students who reside in Isfahan University of Medical Sciences dormitories which control and case groups and the students were divided randomly between these two groups. Data was collected by Cooper Smith Self-esteem questionnaire scale (Cronbach's alpha: 0.85). Two groups were examined by the questionnaire in pre test. Case group received group bibliotherapy for 2 month (8 sessions of 2 hours), while the control group received no training at all. Then, 2 groups were assessed in post test after 1 month. Descriptive statistics (means and frequencies distribution) and inferential statistics (independent t- test, paired t- test and mann whitney) were used and data was analyzed by SPSS20 software. The findings showed that group bibliotherapy had positive and significant effect on general, family, professional and total self esteem of female students living in dormitories, but it had no effect on their social self esteem. Group bibliotherapy can increase female students' self-esteem levels. On the other hand, conducting these studies not only can improve mental health of people, but can also improve their reading habits.

Background The therapeutic abortion law, in accordance with the fatwa issued by our Muslim jurisprudent approved by the parliament in 2005, has made major developments in dealing with cases of therapeutic abortions. Objective This study aimed at identifying the prevalence and causes of therapeutic abortion requests to the Legal Medicine Organization of Fars province, Shiraz, by pregnant teenager mothers. Methods This study was a retrospective, cross-sectional, descriptive survey. In this study, all documents related to therapeutic abortion requests from the Legal Medicine Organization of Fars province (southern Iran) from 2006 to 2013 were investigated. The total sample size included 1664, out of which 142 were teenagers. Sampling was carried out using Convenience method. Data were analyzed using SPSS statistical software, version 16, descriptive statistics and χ2. Results In this study, 142 mothers were under 20 years of age (8.5%). The prevalence of fetal abortion license requests was 110 (78.6%) and for maternal causes was 30 (21.4%). There was no significant statistical correlation between fetal causes in different years (p = 0.083). The most common causes of fetal abortion request were for thalassemia treatment in 78 cases (79.9%) followed by fetal malformations (20.9%); also, the most common maternal cause was thalassemia in 14 cases (51.9%) and depression in three cases (1.11%), respectively. Conclusion Our results showed that after approval of therapeutic abortion law, requests for therapeutic abortion due to fetal causes are extensively increasing. There is still a need for coordination of judicial, medical and legal authorities for prompt notification.

Abstract Objective: To evaluate the correlation between the number of leukocytes and cardiovascular risks associated with birth characteristics, nutritional status and biochemical tests. Methods: Cross-sectional study developed with 475 adolescents, born between 1992 and 2001, in the municipality of Viçosa (MG). Maternal medical records were analyzed in the hospital units, and the following was recorded: birth weight and length, head circumference, chest circumference, Apgar score, gestational age. In adolescents, body mass index, skinfold thickness, body composition, blood count, biochemical tests and clinical variables were also assessed. The statistical analyses was carried out using Statistical Package for Social Sciences (SPSS) version 20.0 and Data Analysis and Statistical Software (STATA) with Kruskal–Wallis, Mann–Whitney, chi-square or Fisher's exact tests and Linear Regression. Significance level was set at α<0.05. The study was approved by the Research Ethics Committee of UFV for studies with human subjects. Results: Weight and birth length, head and chest circumference were higher among boys. In adolescents, the number of leukocytes was higher in individuals with excess weight and body fat and high adiposity index, waist-to-height ratio and waist circumference. Only altered triglycerides showed differences between leukocyte medians. Regardless of the anthropometric variable of the final regression model, the stage of adolescence, number of platelets, eosinophils, monocytes and lymphocytes were associated with the increase in leukocytes. Conclusions: The birth variables were not associated with changes in leukocyte numbers, whereas the anthropometric variables were good indicators for a higher leukocyte count, regardless of the stage of adolescence and gender.

To study the effect of surface organic modified nano-silicon-oxide (SiO(x)) on mechanical properties of A-2186 silicone elastomers. Surface organic modified nano-silicon-oxide (SiO(x)) was added into A-2186 silicone elastomers by weight percentage of 2%, 4% and 6%. The one without addition served as a control. Standard specimens were made according to American Society for Testing Materials (ASTM). Their tensile strength, elongation at break, tear strength, and Shore A hardness were measured. The results were analyzed statistically by SPSS 10.0 software package. The tensile strength in the experimental groups was significantly lower than the control group (P<0.001).The elongation in the experimental groups was lower than the control group, but there was no significant difference between the 2wt% group and the control group (P=0.068). The tear strength in both the 2wt= group and 4wt= group were higher than the control group, and the difference was statistically significant; in addition, the tear strength in 2wt= group was higher than 4wt= group, which also showed statistical significance (P<0.001). With the increase of the added amount of surface modified nano-SiO(x), Shore A hardness increased and there was significant difference among them (P<0.001). Adding surface modified nano-SiO(x) has an effect on mechanical properties of A-2186 silicone elastomer, when 2wt= and 4wt= are added, tear strength of A-2186 improves significantly, with an increase of Shore A hardness and an decrease of tensile strength.

CONTEXT: The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. AIMS: To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. SETTINGS AND DESIGN: Prospective descriptive study. MATERIALS AND METHODS: In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. STATISTICAL ANALYSIS USED: Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. RESULTS: Of the 570 patients undergoing laparoscopic surgery, 17 (3%) had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI) was the most frequent (n = 10, 1.8%), followed by port site bleeding (n = 4, 0.7%), omentum-related complications (n = 2; 0.35%), and port site metastasis (n = 1, 0.175%). CONCLUSIONS: Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit. PMID:23741110

Video-guided laryngoscopy, though unproven in achieving better success rates of laryngoscopy outcome and intubation, seems to provide better glottic visualization compared with direct laryngoscopy. The objective of this study was to compare the efficacy of video-guided laryngoscope (VGL) in the airway management skills of medical students. Medical students throughout their anesthesiology rotations were enrolled in this study. All students received standard training in the airway management during their course and were randomly allocated into two 20 person groups. In Group D, airway management was performed by direct laryngoscopy via Macintosh blade and in Group G intubation was performed via VGL. Time to intubation, number of laryngoscopy attempts and success rate were noted. Successful intubation was considered as the primary outcome. All data were analyzed using SPSS 16 software. Chi-square and Fisher's exact test were used for analysis of categorical variables. For analyzing continuous variables independent t-test was used. P < 0.05 was considered as statistically significant. Number of laryngoscopy attempts was less in Group G in comparison to Group D; this, however, was statistically insignificant (P: 0.18). Time to intubation was significantly less in Group G as compared to Group D (P: 0.02). Successful intubation in Group G was less frequently when compared to Group D (P: 0.66). Need for attending intervention, esophageal intubation and hypoxemic events during laryngoscopy were less in Group G; this, however, was statistically insignificant. The use of video-guided laryngoscopy improved the first attempt success rate, time to intubation, laryngoscopy attempts and airway management ability of medical students compared to direct laryngoscopy.

Despite the increasing interest in Occupational Safety and Health (OSH), seldom studies are available on OSH in medical laboratories from developing countries in general although a high number of injuries occur without proper documentation. It is estimated that every day 6,300 people die as a result of occupational accidents or work-related diseases resulting in over 2.3 million deaths per year. Medical laboratories handle a wide range of materials, potentially dangerous pathogenic agents and exposes health workers to numerous potential hazards. This study evaluated the status of OSH in medical laboratories in Kajiado County, Kenya. The objectives included establishment of biological, chemical and physical hazards; reviewing medical laboratories control measures; and enumerating factors hindering implementation of good practices in OSH. This was a cross-sectional descriptive study research design. Observation check lists, interview schedules and structured questionnaires were used. The study was carried out in 108 medical laboratories among 204 sampled respondents. Data was analysed using statistical package for social science (SPSS) 20 software. The commonest type of hazards in medical laboratories include; bacteria (80%) for Biological hazards; handling un-labelled and un-marked chemicals (38.2%) for chemical hazards; and laboratory equipment's dangerously placed (49.5%) for Physical hazards. According to Pearson's Product Moment Correlation analysis, not-wearing personal protective equipment's was statistically associated with exposure to hazards. Individual control measures were statistically significant at 0.01 significance level. Only 65.1% of the factors influencing implementation of OSH in medical laboratories were identified. Training has the highest contribution to good OSH practices.

To Analyze the influence factors on the complications of percutaneous dilational tracheotomy. Between August 2008 and February 2014, there were 3 450 patients with the indications of tracheotomy accepted percutaneous dilational tracheostomy, mainly using percutaneous dilational and percutaneous guide wire forceps in these cases. Statistical analysis was performed by SPSS 19.0 software on postoperative complications, the possible influence factors including age, gender, etiology, preoperative hypoxia, obesity, preoperative pulmonary infection, state of consciousness, operation method, operation doctor and whether with tracheal intubation. Among 3 450 patients, there were 164 cases with intraoperative or postoperative complications, including postoperative bleeding in 74 cases (2.14%), subcutaneous emphysema in 54 cases (1.57%), wound infection in 16 cases (0.46%), pneumothorax in 6 cases (0.17%), mediastinal emphysema in 5 cases (0.14%), operation failed and change to conventional incision in 4 cases (0.12%), tracheoesophageal fistula in 2 cases (0.06%), death in 3 cases(0.09%).Obesity, etiology, preoperative hypoxia, preoperative pulmonary infection, state of consciousness and operation method were the main influence factors, with significant statistical difference (χ(2) value was 0.010, 0.000, 0.002, 0.000, 0.000, 0.000, all P < 0.05). Gender, age, operation doctor and whether there was the endotracheal intubation were not the main influence factors. There was no significant statistical difference (P > 0.05). Although percutaneous dilational tracheostomy is safe, but the complications can also happen. In order to reduce the complications, it is need to pay attention to the factors of obesity, etiology, preoperative hypoxia, preoperative pulmonary infection, state of consciousness and operation method.

Computational procedures for probing interactions in OLS and logistic regression: SPSS and SAS implementations.

PubMed

Hayes, Andrew F; Matthes, Jörg

2009-08-01

Researchers often hypothesize moderated effects, in which the effect of an independent variable on an outcome variable depends on the value of a moderator variable. Such an effect reveals itself statistically as an interaction between the independent and moderator variables in a model of the outcome variable. When an interaction is found, it is important to probe the interaction, for theories and hypotheses often predict not just interaction but a specific pattern of effects of the focal independent variable as a function of the moderator. This article describes the familiar pick-a-point approach and the much less familiar Johnson-Neyman technique for probing interactions in linear models and introduces macros for SPSS and SAS to simplify the computations and facilitate the probing of interactions in ordinary least squares and logistic regression. A script version of the SPSS macro is also available for users who prefer a point-and-click user interface rather than command syntax.

Introduction: Clinical reasoning is one of the most important skills in the process of training a medical student to become an efficient physician. Assessment of the reasoning skills in a medical school program is important to direct students’ learning. One of the tests for measuring the clinical reasoning ability is Clinical Reasoning Problems (CRPs). The major aim of this study is to measure psychometric qualities of CRPs and define correlation between this test and routine MCQ in cardiology department of Shiraz medical school. Methods: This study was a descriptive study conducted on total cardiology residents of Shiraz Medical School. The study population consists of 40 residents in 2014. The routine CRPs and the MCQ tests was designed based on similar objectives and were carried out simultaneously. Reliability, item difficulty, item discrimination, and correlation between each item and the total score of CRPs were all measured by Excel and SPSS software for checking psycometeric CRPs test. Furthermore, we calculated the correlation between CRPs test and MCQ test. The mean differences of CRPs test score between residents’ academic year [second, third and fourth year] were also evaluated by Analysis of variances test (One Way ANOVA) using SPSS software (version 20)(α=0.05). Results: The mean and standard deviation of score in CRPs was 10.19 ±3.39 out of 20; in MCQ, it was 13.15±3.81 out of 20. Item difficulty was in the range of 0.27-0.72; item discrimination was 0.30-0.75 with question No.3 being the exception (that was 0.24). The correlation between each item and the total score of CRP was 0.26-0.87; the correlation between CRPs test and MCQ test was 0.68 (p<0.001). The reliability of the CRPs was 0.72 as calculated by using Cronbach's alpha. The mean score of CRPs was different among residents based on their academic year and this difference was statistically significant (p<0.001). Conclusion: The results of this present investigation revealed that CRPs could be reliable test for measuring clinical reasoning in residents. It can be included in cardiology residency assessment programs. PMID:29344528

2013-05-01

The ultracold molecular conversion rate occurring in an adiabatic ramp through a Fano-Feshbach resonance is studied and compared in two statistical models. One model, the so-called stochastic phase-space sampling (SPSS) [Hodby , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.94.120402 94, 120402 (2005)] evaluates the overlap of two atomic distributions in phase space by sampling atomic pairs according to a phase-space criterion. The other model, the chemical equilibrium theory (ChET) [Watabe and Nikuni, Phys. Rev. APLRAAN1050-294710.1103/PhysRevA.77.013616 77, 013616 (2008)] considers atomic and molecular distributions in the limit of the chemical and thermal equilibrium. The present study applies SPSS and ChET to a prototypical system of K+K→ K2 in all the symmetry combinations, namely Fermi-Fermi, Bose-Bose, and Bose-Fermi cases. To examine implications of the phase-space criterion for SPSS, the behavior of molecular conversion is analyzed using four distinct geometrical constraints. Our comparison of the results of SPSS with those of ChET shows that while they appear similar in most situations, the two models give rise to rather dissimilar behaviors when the presence of a Bose-Einstein condensate strongly affects the molecule formation.

Thrombocytopenia is a common hematologic abnormality during pregnancy. Pregnant women with thrombocytopenia have a higher risk of bleeding excessively during or after childbirth, particularly if they need to have a cesarean section or other surgical intervention during pregnancy, labor or in the puerperium. The main aim of this study was to determine the prevalence of thrombocytopenia among pregnant women attending antenatal care service at Gondar University Hospital, northwest Ethiopia. A cross-sectional study was used to assess the prevalence of thrombocytopenia among pregnant women attending antenatal care service at Gondar University Hospital from January to April 2015. A total of 217 pregnant women were included in the study and a structured pretested questionnaire was used to obtain sociodemographic information, nutritional factors, obstetrics and gynecological factors, history and clinical condition. Blood samples were collected for platelet count and other platelet parameters, which were determined by using SysmexKX 21 automation. The data were entered to Epi info version 6 software and analyzed using SPSS version 20 software. Bivariable and multivariable statistical analyses were used to evaluate the effect of independent variable over the dependent variable. A p -value of <0.05 was considered as statistically significant. A total of 217 women receiving antenatal care service at Gondar University Hospital participated in the study. Thrombocytopenia among 19 pregnant women showed a prevalence of 8.8%. The mean ± standard deviation platelet count was 238.85×10 9 /L (±74.57). Thrombocytopenia was significantly associated with patients who lived rurally (crude odds ratio =4.3, 95% confidence interval 1.48-12.76). The prevalence of thrombocytopenia was 8.8% predominantly with mild type of thrombocytopenia. Thrombocytopenia was higher among pregnant women who lived rurally. Therefore, health care providers should screen routinely for thrombocytopenia to avoid excessive bleeding during pregnancy, especially in women who live rurally.

SU-E-J-92: CERR: New Tools to Analyze Image Registration Precision.

2012-06-01

To present new tools in CERR (The Computational Environment for Radiotherapy Research) to analyze image registration and other software updates/additions. CERR continues to be a key environment (cited more than 129 times to date) for numerous RT-research studies involving outcomes modeling, prototyping algorithms for segmentation, and registration, experiments with phantom dosimetry, IMRT research, etc. Image registration is one of the key technologies required in many research studies. CERR has been interfaced with popular image registration frameworks like Plastimatch and ITK. Once the images have been autoregistered, CERR provides tools to analyze the accuracy of registration using the following innovative approaches (1)Distance Discordance Histograms (DDH), described in detail in a separate paper and (2)'MirrorScope', explained as follows: for any view plane the 2-d image is broken up into a 2d grid of medium-sized squares. Each square contains a right-half, which is the reference image, and a left-half, which is the mirror flipped version of the overlay image. The user can increase or decrease the size of this grid to control the resolution of the analysis. Other updates to CERR include tools to extract image and dosimetric features programmatically and storage in a central database and tools to interface with Statistical analysis software like SPSS and Matlab Statistics toolbox. MirrorScope was compared on various examples, including 'perfect' registration examples and 'artificially translated' registrations. for 'perfect' registration, the patterns obtained within each circles are symmetric, and are easily, visually recognized as aligned. For registrations that are off, the patterns obtained in the circles located in the regions of imperfections show unsymmetrical patterns that are easily recognized. The new updates to CERR further increase its utility for RT-research. Mirrorscope is a visually intuitive method of monitoring the accuracy of image registration that improves on the visual confusion of standard methods. © 2012 American Association of Physicists in Medicine.

Exploring item and higher order factor structure with the Schmid-Leiman solution: syntax codes for SPSS and SAS.

Wolff, Hans-Georg; Preising, Katja

To ease the interpretation of higher order factor analysis, the direct relationships between variables and higher order factors may be calculated by the Schmid-Leiman solution (SLS; Schmid & Leiman, 1957). This simple transformation of higher order factor analysis orthogonalizes first-order and higher order factors and thereby allows the interpretation of the relative impact of factor levels on variables. The Schmid-Leiman solution may also be used to facilitate theorizing and scale development. The rationale for the procedure is presented, supplemented by syntax codes for SPSS and SAS, since the transformation is not part of most statistical programs. Syntax codes may also be downloaded from www.psychonomic.org/archive/.

This book is written from the perspective that statistics is an integrated set of tools used together to uncover the story contained in numerical data. Accordingly, the book comes with a disk containing a series of real data sets to motivate discussions of appropriate methods of analysis. The presentation is based on a conceptual approach supported by an understanding of underlying mathematical foundations. Students learn that more than one method of analysis is typically needed and that an ample characterization of results is a critical component of any data analytic plan. The use of real data and SPSS to perform computations and create graphical summaries enables a greater emphasis on conceptual understanding and interpretation.

To introduce a teaching method for gingival retraction, and evaluate its efficacy for implementation into experimental curricula. First, two kinds of animal models using pigs and cows (below 6 months of age) were established. Twenty-two experienced prosthodontists were then asked to apply gingival retraction on each animal model and evaluate the biofidelity of the 2 models' dento-gingival environment. The data was analyzed with SPSS19.0 software package for paired t test.Then, eighty pre-internship students were randomly divided into 2 groups. Besides the traditional teaching (lecture-based teaching), the experimental group (group A) also had access to skill training (using animal models to practice gingival retraction), while the control group (group B) only used the traditional teaching modality. All students' performance in gingival retraction and impression taking were evaluated in their internship. The data was analyzed with SPSS19.0 software package for Chi-square test. Both pig and cow's dento-gingival environment were similar to that of human being, and there was no significant difference between the two models'biofidelities (P>0.05). In addition, both the effect of gingival retraction and the quality of impression in group A were significantly better than those in group B (P<0.05). Compared with the traditional strategy,practising gingival retraction on animal models can offer greater opportunities for skill development,and be implemented for a wider range of applications.

Mortality and morbidity related to traumatic brain injuries still remain high in patients. Many authors reported the importance of Selenium in maintaining the integrity of brain functions. This fact is supported by clinical evidence that therapy with selenium supplementation could help patients suffering from brain disorders like neurodegenerative diseases. The aim of our study was to assess the relationship between Selenium concentration in serum and evolution of comatose patients with severe traumatic brain injury, in the first week of admission, and the correlation between selenium and C-reactive protein. This case-control study was conducted with 64 comatose patients with TBI, in the Department of Anesthesiology and Reanimation, IbnSina University Hospital and Hospital of specialties in Rabat-Morocco, and healthy volunteers recruited in Blood transfusion center of Rabat. Blood sampling was collected from TBI patients, in the first week (3h after admission and each 48h during one week), and from healthy volunteers one time. Concentration of Se in serum was determined by electrochemical atomic absorption spectrometry. Statistical analysis was performed using Statistical software (SPSS) and the cases and controls were compared using the Mann-Whitney U test. A P-value < 0.05 was considered to be statistically significant. Comparison selenium concentration in the first day (D0), third day (D2) and fifth day according to the death and survival statue in patients did not show statistical significance (p > 0.05). Selenium concentration of D0 in patients and Selenium concentration in control group also did not show statistical significance (p > 0.05). Similarly, we did not report a correlation between selenium and C-reactive protein. According to our data selenium and CRP may not play a role in progression of coma state in patients with severe traumatic brain injury.

The aim of this randomized clinical trial was to assess the efficacy of exclusive lingual nerve block (LNB) in achieving selective lingual soft-tissue anesthesia in comparison with conventional inferior alveolar nerve block (IANB). A total of 200 patients indicated for the extraction of lower premolars were recruited for the study. The samples were allocated by randomization into control and study groups. Lingual soft-tissue anesthesia was achieved by IANB and exclusive LNB in the control and study group, respectively. The primary outcome variable studied was anesthesia of ipsilateral lingual mucoperiosteum, floor of mouth and tongue. The secondary variables assessed were (1) taste sensation immediately following administration of local anesthesia and (2) mouth opening and lingual nerve paresthesia on the first postoperative day. Data analysis for descriptive and inferential statistics was performed using SPSS (IBM SPSS Statistics for Windows, Version 22.0, Armonk, NY: IBM Corp. Released 2013) and a P < 0.05 was considered statistically significant. In comparison with the control group, the study group (LNB) showed statistically significant anesthesia of the lingual gingiva of incisors, molars, anterior floor of the mouth, and anterior tongue. Exclusive LNB is superior to IAN nerve block in achieving selective anesthesia of lingual soft tissues. It is technically simple and associated with minimal complications as compared to IAN block.

Common mental disorder (CMD) is prevalent in industrialized and non-industrialized countries. The prevalence of CMD among university students was 28.8-44.7% and attributed to several risk factors, such as schooling. The aim of this study was to assess the prevalence and risk factors of CMD. In addition, the association between CMD and academic performance was tested. Institution based cross-sectional study was conducted with 422 students at Debre Berhan university from March to April 2015. CMD was the primary outcome variable whereas academic performance was the secondary outcome variable. Kessler psychological distress (K10) scale was used to assess CMD. Bivariate and multiple logistic regression analysis were performed for modeling the primary outcome variable; independent samples T test and linear regression analysis were carried out for modeling the secondary outcome variable. The strength of association was interpreted using odds ratio and regression coefficient (β) and decision on statistical significance was made at a p value of 0.05. Data were entered using EPI-data version 3.1 software and analyzed using the Statistical Package for the Social Sciences (SPSS) version 20.01 software. The prevalence of CMD was 63.1%. Field of study (p = 0.008, OR = 0.2, 95% CI 0.04-0.61), worshiping (p = 0.04, OR = 1.8, 95% CI 1.02-3.35), insomnia (p < 0.001, OR = 3.8, 95% CI 2.21-6.57), alcohol drinking (p = 0.006, OR = 2.7, 95% CI 1.33-5.66), and headache (p = 0.02, OR = 2.1, 95% CI 1.10-3.86) were identified risk factors for CMD. The mean cumulative grade point average of students with CMD was lower by 0.02 compared to those without CMD, but not statistically significant (p = 0.70, β = -0.02, 95% CI -0.15 to 0.10). CMD explained only 0.8% (r 2  = 0.008) of the difference in academic performance between students. At least three out of five students fulfilled CMD diagnostic criteria. The statistically significant risk factors were field of study, worshiping, insomnia, alcohol drinking, and headache. Moreover, there was no statistically significant association between CMD and academic performance. Undertaking integrated evidence-based intervention focusing on students with poor sleep quality, poor physical health, and who drink alcohol is essential if the present finding confirmed by a longitudinal study.

To observe the exposure levels of extremely low frequency electromagnetic fields in workplaces and to analyze the effects of extremely low frequency electromagnetic radiation on cardiovascular system of occupationally exposed people. Intensity of electromagnetic fields in two workplaces (control and exposure groups) was detected with EFA-300 frequency electromagnetic field strength tester, and intensity of the noise was detected with AWA5610D integral sound level. The information of health physical indicators of 188 controls and 642 occupationally exposed workers was collected. Data were analyzed by SPSS17.0 statistic software. The intensity of electric fields and the magnetic fields in exposure groups was significantly higher than that in control group (P < 0.05), but there was no significant difference of noise between two workplaces (P > 0.05). The results of physical examination showed that the abnormal rates of HCY, ALT, AST, GGT, ECG in the exposure group were significantly higher than those in control group (P < 0.05). There were no differences of sex, age, height, weight between two groups (P > 0.05). Exposure to extremely low frequency electromagnetic radiation may have some effects on the cardiovascular system of workers.

Anxiety is one of the most common psychological issues among all age groups including children. The main role of parents has been known to support their children. Being far away from a source of support has been shown to be a potential trigger for childhood anxiety. Periodical jobs, including offshore work, are among the main reasons for absence of one of the parents. Therefore, this study aims to assess anxiety in children of National Iranian Drilling Company offshore staff. In this historical cohort study, 160 students including 80 boys and 80 girls were selected through convenient random sampling from the schools of National Iranian Drilling Company. Data were collected using Revised Children's Manifest Anxiety Inventory (by Reynolds and Richmond), consisting 37 items and a demographic questionnaire. The collected data were statistically analyzed by t-test and logistic regression tests through SPSS software. The mean anxiety score was 12.80 among offshore staff's children and 11.67 among the children of the based staff. The ratio of manifest anxiety among the offshore workers' children was significantly more than the based ones'. Based on the findings, offshore fathers' job affects the anxiety of the children.

The type of body fat distribution has an important role for identifying risk of diseases. One of the simple anthropometric indexes for estimating type of body fat distribution is waist circumference index. This study is aimed to determine the type of body fat distribution in postmenopausal women and its related factors. This is a cross sectional descriptive analytical study. Samples were 278 postmenopausal women in Isfahan who were selected by stratified sampling and then were invited to 64 health centers of Isfahan. Data was gathered using a questionnaire and standard meter. Data was analyzed using SPSS software and descriptive and inferential statistics. Results showed that in postmenopausal women the mean of waist circumference index was 93.63 (10.66) and its range was 54 to 119 cm. There was a meaningful relation between job, educational status, total pregnancies, total deliveries, age of first pregnancy, lactation history and menopausal age with waist circumference index. Results showed that the type of body fat distribution of postmenopausal women is of android type. Considering side effects of this kind of distribution, necessary teachings about healthy eating, movement and exercises must be given to women of these ages.

No previous studies have addressed the integrated relationships among system quality, service quality, job satisfaction, and system performance; this study attempts to bridge such a gap with evidence-based practice study. The convenience sampling method was applied to the information system users of three hospitals in southern Taiwan. A total of 500 copies of questionnaires were distributed, and 283 returned copies were valid, suggesting a valid response rate of 56.6%. SPSS 17.0 and AMOS 17.0 (structural equation modeling) statistical software packages were used for data analysis and processing. The findings are as follows: System quality has a positive influence on service quality (γ11= 0.55), job satisfaction (γ21= 0.32), and system performance (γ31= 0.47). Service quality (β31= 0.38) and job satisfaction (β32= 0.46) will positively influence system performance. It is thus recommended that the information office of hospitals and developers take enhancement of service quality and user satisfaction into consideration in addition to placing b on system quality and information quality when designing, developing, or purchasing an information system, in order to improve benefits and gain more achievements generated by hospital information systems.

Urolithiasis is rare among renal transplant recipients and its management has not been clearly defined. This multicentre retrospective study was organised by the Comité de Transplantation de l'Association Française d'Urologie (French Urology Association transplantation committee). Statistical analysis was performed with SPSS 19 software. Ninety-five patients were included in this study. Renal transplant urolithiasis was an incidental finding in 55% of cases, mostly on a routine follow-up ultrasound examination. One half of symptomatic stones were due to urinary tract infection and the other half were due to an episode of acute renal failure. The initial management following diagnosis of urolithiasis was double J stenting (27%), nephrostomy tube placement (21%), or watchful waiting (52%). Definitive management consisted of: watchful waiting (48%), extracorporeal lithotripsy (13%), rigid or flexible ureteroscopy (26%), percutaneous nephrolithotomy (11%) and surgical pyelotomy (2%). All transplants remained functional following treatment of the stone. The main limitation is the retrospective design. The incidence of lithiasis could be higher in kidney transplanted patients due to a possible anatomical or metabolical abnormalities. The therapeutic management of renal transplant urolithiasis appears to be comparable to that of native kidney urolithiasis.

Objective. To approach general principles of color matching for crew module layout and to provide its ergonomical evaluation with basic data. Method. First, according to some ergonomic rules a virtual reality experimental system was set up, then 64 subjects of different ages and with some background of spaceflight were offered a color matching example according to their own choice in advance. Finally, all the hues, saturations, and lightnesses of the selected colors and their total number were statistically analyzed by SPSS 8.0 software. Result. After choosing the colors for items (standard cabinets, floor, handrails, supports and etc.) in the crew cabin, the mean kinds of color hue matching in the cockpit was 5. In addition, above half of subjects endorsed the example colors but its saturation and lightness were a little higher than those of the example every time. Although its distribution was discrete, there still was a common agreement on color matching (about 50%). Conclusion. When the color matching of crew module in long time flight was ergonomically designed, generally, cool and warm hues should be taken into consideration, and their total number need be controlled to be under 5 so as to satisfy human psychological characters.

Background Universal goniometer (UG) is commonly used as a standard method to evaluate range of motion (ROM) as part of joint motions. It has some restrictions, such as involvement of both hands of the physician, leads to instability of hands and error. Nowadays smartphones usage has been increasing due to its easy application. Objectives The study was designed to compare the smartphone inclinometer-based app and UG in evaluation of ROM of elbow. Materials and Methods The maximum ROM of elbow in position of flexion and pronation and supination of forearm were examined in 60 healthy volunteers with UG and smartphone. Data were analyzed using SPSS (ver. 16) software and appropriate statistical tests were applied, such as paired t-test, ICC and Bland Altman curves. Results The results of this study showed high reliability and validity of smartphone in regarding UG with ICC > 0.95. The highest reliability for both methods was in elbow supination and the lowest was in the elbow flexion (0.84). Conclusions Smartphones due to ease of access and usage for the physician and the patient, may be good alternatives for UG. PMID:27625754

The haptoglobin-hemoglobin (Hp-Hb) complex plays a significant role in regulating immune responses and acts as a bacteriostatic agent. Haptoglobin polymorphisms result in different Hb binding affinities. This study sought to assess whether Hp 2-2 could be a genetic determinant for increasing the risk of peri-implantitis and chronic periodontitis. Of the Iranian subjects referred to the Department of Periodontics, Shahid Beheshti University, Tehran, 203 were entered into the study, including 117 patients and 86 periodontally healthy individuals. Polymerase chain reaction (PCR) was performed for genotyping. Data were analyzed by Kruskal-Wallis test using the SPSS statistics software package. The prevalence of Hp 2-2, 2-1, and 1-1 did not differ significantly between patients and healthy subjects (P > 0.05). The highest frequencies of Hp 1-1, 2-1, and 2-2 genotypes were seen in the control (7%), peri-implantitis (51%) and periodontitis (64%) groups, respectively. Haptoglobin polymorphisms may not play a role in development of peri-implantitis or chronic periodontitis among Iranians but we strongly suggest researchers to evaluate this polymorphism in further studies on larger sample sizes, different populations, and other types of periodontitis. © 2013 Wiley Publishing Asia Pty Ltd.

Breakfast is the most important daily meal, but neglected more than other meals by children and adolescents. The aim of this study was to evaluate the effectiveness of an educational intervention, based on the Theory of Reasoned Action (TRA) to increase breakfast consumption among school children in Bandar Abbas, Iran. In this quasi experimental study which was conducted in 2012, 88 students of four secondary schools in Bandar Abbas, south of Iran, were enrolled. Multi-stage cluster sampling was performed with random allocation of interventional and control groups. The study tool was a questionnaire which was filled by the students before and two months after the educational intervention. For data analysis, statistical tests including paired-samples t-test, independent samples t-test, Wilcoxon test, and Mann-Whitney test were used through SPSS v.18 software. The result of the study showed that application of TRA significantly increased scores of behavior of breakfast consumption (p<0.01). After the intervention, a significant increase was revealed in all nutrition intakes, except for fat and sugar (p<0.01). The findings support application of the TRA in improving the intention and behavior of breakfast consumption. Applying this theory for designing interventions to increase breakfast eating is recommended.

Aims: This study evaluated effect of infection control barriers on light intensity (LI) of light-curing unit (LCU) and microhardness of composite. Materials and Methods: Four different disposable barriers (n = 30) were tested against the control. LI for each barrier was measured with Lux meter. One hundred and fifty Teflon molds were equally divided into five groups of thirty each. Composite was filled in bulk in these molds and cured without and with barrier. Microhardness was evaluated on top and bottom surface of composite specimen with microhardness testing machine and hardness ratio (HR) was derived. Statistical Analysis Used: One-way analysis of variance, Tukey's honestly significant difference test, and paired t-test using SPSS version 18 software. Results: All barriers had significantly reduced the baseline LI of LCU (P < 0.0001), but only Cure Elastic Steri-Shield and latex cut glove pieces (LCGP) significantly reduced the microhardness of the composite (P < 0.05). However, HR determined inadequate curing only with LCGP. Conclusions: Although entire tested barrier significantly reduced the LI; none, except LCGP markedly affected the degree of cure of the composite. PMID:29279622

Halitosis is defined as a noticeable unpleasant odor from the mouth. It is a medico-social problem that affects a significant number of people around the world. Research reveals that nearly 50% of the adult population has halitosis. To determine level of awareness of halitosis and prevalence of the condition amongst students in tertiary institutions as a baseline survey. For this project, 100 students from three tertiary institutions in Lagos state were chosen: University of Lagos, Lagos State University, Ojo campus and Yaba College of Technology. A semi-structured questionnaire and practical testing/diagnostic tool were utilized. Data collected was collated and analyzed using Microsoft Excel 2007 and SPSS statistical software. Most of the respondents were single and Christian. Level of awareness of halitosis was high. Results showed that 15%, 2% and 22% from UNILAG, LASU and YCT respectively said they had halitosis. Using the diagnostic tool, 6%, 8% and 2% respectively were positive for halitosis. There is high level of awareness of halitosis among the respondents. The prevalence of the disorder is low, however, it is recommended that enlightenment campaigns be mounted in schools to improve level of awareness and treatment seeking.

Performance of signalized intersection has declined due to a large number of motorcycles. The number of motorcycles reached 98.2 million units and the composition of motorcycles has reached around 81.7% of the total composition of vehicles in Indonesia (AISI, 2017). To solve that problem, the red box for motorcycles are provided at the signalized intersection. Red box for the motorcycle at signalized intersections was developed from the concept of Advance Stop Line (ASL) for bicycles. The Red Box was developed to split the queue between motorcycles and other vehicles when waiting at red light. This paper aims to evaluate the influence of the red box dimension and red time operation differences. The survey was conducted as many as 30 cycles of traffic signals per day. The data were analyzed using software IBM SPSS Statistics 20 by using Analysis of Variance (ANOVA) to obtain p-value (significant). The analysis shows that there are insignificant influences between the occupancy rates to the dimension of Red Box. Furthermore, that there is a significant difference that shows the dependency of only motorcycles in the Red Box Area towards red time operation.

Electronic Health Record (EHR) is one of the most important achievements of information technology in healthcare domain, and if deployed effectively, it can yield predominant results. The aim of this study was a SWOT (strengths, weaknesses, opportunities, and threats) analysis in electronic health record implementation. This is a descriptive, analytical study conducted with the participation of a 90-member work force from Hospitals affiliated to Tehran University of Medical Sciences (TUMS). The data were collected by using a self-structured questionnaire and analyzed by SPSS software. Based on the results, the highest priority in strength analysis was related to timely and quick access to information. However, lack of hardware and infrastructures was the most important weakness. Having the potential to share information between different sectors and access to a variety of health statistics was the significant opportunity of EHR. Finally, the most substantial threats were the lack of strategic planning in the field of electronic health records together with physicians' and other clinical staff's resistance in the use of electronic health records. To facilitate successful adoption of electronic health record, some organizational, technical and resource elements contribute; moreover, the consideration of these factors is essential for HER implementation.

Many studies have shown the benefits of diathermy over scalpel for making skin incisions in terms of post operative pain and post operative analgesics requirement. The objective of the study is to compare the pain following incision by scalpel and diathermy for skin in ENT surgery. We conducted a prospective, randomized study and compared early post operative pain and analgesics requirement in patients undergoing ENT and Head and Neck surgery in Department of ENT at Kathmandu Medical College from September 2016 to August 2017. The statistical analysis was done using MS Excel and SPSS software. Out of 65 participants, 31 were allocated in scalpel group and 30 were allocated in diathermy group. The mean VAS score was significantly greater in scalpel group as compared to diathermy group in post operative 12, 24 and 48 hours (P<0.05). The mean ketorolac requirement was significantly more in scalpel group than in diathermy group in post operative 24 hours. The early post operative pain is less in ENT-Head and Neck surgery patients with skin incision by diathermy as compared to the patients with skin incision by scalpel.

Anthropometric measurement is essential for identification of both victims and suspects. Often, this data is not readily available in a crime scene situation. The availability of one data set should help in predicting the other. This study was hypothesised on the basis of a correlation and geometry between the tooth length and various body measurements. To correlate face, palm, foot and stature measurements with tooth length. To derive a regression formula to estimate the various measurements from tooth length. The present study was conducted on Dravidian dental students in the age group 18 - 25 with a sample size of 372. All of the dental and physical parameters were measured using standard anthropometric equipments and techniques. The data was analysed using SPSS software and the methods used for statistical analysis were linear regression analysis and Pearson correlation. The parameters (incisor height (IH), face height (FH), palm length (PL), foot length (FL) and stature (S) showed nil to mild correlation (R = 0.2 ≤ 0.4) except for palm length (PL) and foot length (FL). (R>0.6). It is concluded that odontometric data is not a reliable source for estimating the face height (FH), palm length (PL), foot length (FL) and stature (S).

Nurses working in outpatient departments face tremendous pressure from multiple sources. The effect of nurse professional commitment on continued professional development is an issue worth exploring further. This study explored relationships among nurses' personal attributes, work stress and professional commitment. The Lazarus cognitive appraisal model framed the research plan design. Tools used included stress level and professional commitment scales for healthcare professionals. Of 180 questionnaires sent to outpatient department nurses nurses, 171 (95%) were returned and used in analysis. SPSS 12.0 for windows software was used for statistical analysis. We found a significant negative correlation between work stress and professional commitment and no significant relationship between level of education and either ability to handle work stress or professional commitment. Years of work experience, age and position all correlated positively with ability to handle work stress. Years of work experience correlated positively with professional commitment. This study suggests that nurses experience the highest work stress levels during their first five years of work. Findings show that providing nurses a clear career development path, in addition to attractive incentives and a reasonable workload, is essential to reducing work stress, bolstering professional commitment and increasing retention.

To investigate the association between coronary heart disease (CHD) and erectile dysfunction (ED) in Chinese Han population. Patients who went to the andrological out-patient clinic of our hospital between August 1, 2015 and May 1, 2016 and met all eligible criteria were enrolled in this study. The patients diagnosed as ED using self-administered International Index of Erectile Function-5 (IIEF-5) questionnaire were considered as case group and others were considered as control. The cases were categorized as mild, moderate, and severe ED. Subjects were interviewed for the history of CHD. Uni- and multivariate logistic regression models were used to calculate odds ratios (ORs) and corresponding 95% confidence intervals (CIs) using the SPSS 18.0 software. A total of 240 participants (56 ED patients and 184 controls) were enrolled. CHD prevalence was higher in cases without statistical significance (OR = 1.20, 95%CI = 0.63-2.29; p = 0.58). Results of adjusted analysis also showed a non-significantly increased risk (OR = 1.25, 95%CI = 0.55-2.85; p = 0.59). Stratified analysis by severity of ED revealed similar results. This study suggests no significant association exists between CHD and ED in Chinese Han population. PMID:28903442

Lichen planus is a mucocutaneous disease which is relatively common and in 30-70% of patients, mucosal lesions can be seen and known as a precancerous lesion but its etiology is not completely understood. Desmogleins I and III are the main desmosomal transmembrane proteins. These proteins have been identified as the autoantigen of the autoimmune disease. The aim of this study was evaluation of serum autoantibodies against desmogleins Ι, ΙΙΙ in oral lichen planus . We attempted to determine the etiology of this disease with evaluation of these serum factors. Thirty-five patients with oral lichen planus and 35 healthy controls were recruited and tested for serum autoantibodies against desmogleins Ι, ΙΙΙ and indirect immunofluorescence also performed. Data were analyzed by statistical-analytical methods (Independent sample t -test) with using the SPSS.15 software. Serum autoantibody against desmoglein Ι had no significant difference in the two groups ( P =0.31 ) but significant increase in serum autoantibody to desmoglein ΙΙΙ was found in patients with oral lichen planus ( P =0.00) . It seems that autoantibody against desmoglein III has a significant role in the pathogenesis of oral lichen planus.

Introduction: The overwhelming effects of cancer could be catastrophic for the patients and their family members, putting them at risk of experiencing uncertainty, loss, and an interruption in life. Also, it can influence their sense of meaning, a fundamental need equated with the purpose in life. Accordingly, this study aimed to compare the meaning in life (MiL) of patients with cancer and their family members. Methods: This descriptive comparative study was conducted on 400 patients with cancer and their family members admitted to university hospitals in Tabriz and Ardebil provinces, Iran. The participants were sampled conveniently and the Life Evaluation Questionnaire (LEQ) were used for collecting data analyzed through descriptive and inferential statistics in SPSS ver. 13 Software. Results: The mean score for the MiL of the patients with cancer and their family members was 119 (16.92) and 146.2 (17.07), respectively. There was a significant difference between patients with cancer and their family members in terms of MiL. Conclusion: The MiL of patients with cancer is lower than that of their family members, which indicates the need for further attention to the psychological processes and their modification in Iranian healthcare systems.

To determine the importance of fasting calcium/creatinine ratio in patients with calcium stones and its relation with hypercalciuria and phospho-calcium metabolism. Cross-sectional study including 143 patients divided into two groups according to fasting calcium/creatinine. Group 1: 66 patients (calcium/ creatinine<0.11); Group 2: 77 patients (calcium/ creatinine>0.11). A comparative study is performed between groups including phospho-calcium metabolism parameters and excretion of urinary lithogenic markers. Linear correlation studying calciuria and fasting calcium/ creatinine was performed. SPSS 17.0 statistical analysis software was used, considering p≤0.05. It is noteworthy that group 2 had increased 24 h urine calcium excretion in comparison to group 1 (229.3 vs 158.1; p=0.0001) and calcium/citrate (0.47 vs 0.34; p=0.001). There is a positive and significant correlation between calcium levels in 24 h urine and fasting calcium/creatinine (R=0.455; p=0.0001) and a cutoff is set at 0.127 (sensitivity 72%, specificity 66%) to determine hypercalciuria (>260 mg in 24 h). Increased fasting calcium/creatinine determines increased 24 hours calcium excretion, although the sensitivity and specificity to determine hypercalciuria is not high.

In order to choose the best veneering porcelain for diatomite-based dental ceramic substrate, the bonding strength between diatomite-based dental ceramics and veneering porcelains was measured, and the microstructure and elements distribution of interface were analyzed. The coefficient of thermal expansion (CTE) of diatomite-based dental ceramics was detected by dilatometry. Three veneering porcelain materials were selected with the best CTE matching including alumina veneering porcelain (group A), titanium porcelain veneering porcelain (group B), and E-max veneering porcelain (group C). Shear bonding strength was detected. SEM and EDS were used to observe the interface microstructure and element distribution. Statistical analysis was performed using SPSS 17.0 software package. The CTE of diatomite-based dental ceramics at 25-500 degrees centigrade was 8.85×10-6K-1. The diatomite-based substrate ceramics combined best with group C. Shear bonding strength between group A and C and group B and C both showed significant differences(P<0.05). SEM and EDS showed that the interface of group C sintered tightly and elements permeated on both sides of the interface. The diatomite-based substrate ceramics combines better with E-max porcelain veneer.

Statement of the Problem: School is one of the places with the greatest prevalence of occurrence of traumatic dental injuries. Purpose: The aim of this study was to assess the knowledge levels and attitudes of elementary school teachers towards dental trauma and its management. Materials and Method: In this cross-sectional study, 281 elementary school teachers were selected through cluster sampling to answer the prepared questionnaire. The data obtained from the questionnaires were analyzed in SPSS software by using ANOVA test and t-test. p Value<0.05 was considered to be significant. Results: The total knowledge and attitude were low and normal, respectively. No previous exposure to or close observation of a dental trauma was reported by 61.2% of teachers; while, 12.5% were trained on dental traumas first aid management. There was statistically significant relationship between the teacher’s knowledge and previous first aids training. Conclusion: The knowledge of schoolteachers on emergency management of dental trauma is poor. Therefore, it seems to be helpful to consider the management of dental injuries especially avulsed teeth as a part of teachers' education. PMID:29034277

Individual and organizational factors are the factors influencing traumatic occupational injuries. The aim of the present study was the short path analysis of the severity of occupational injuries based on individual and organizational factors. The present cross-sectional analytical study was implemented on traumatic occupational injuries within a ten-year timeframe in 13 large Iranian construction industries. Modeling and data analysis were done using the structural equation modeling (SEM) approach and the IBM SPSS AMOS statistical software version 22.0, respectively. The mean age and working experience of the injured workers were 28.03 ± 5.33 and 4.53 ± 3.82 years, respectively. The portions of construction and installation activities of traumatic occupational injuries were 64.4% and 18.1%, respectively. The SEM findings showed that the individual, organizational and accident type factors significantly were considered as effective factors on occupational injuries' severity (P < 0.05). Path analysis of occupational injuries based on the SEM reveals that individual and organizational factors and their indicator variables are very influential on the severity of traumatic occupational injuries. So, these should be considered to reduce occupational accidents' severity in large construction industries.

Our aim was to determine the service quality of delivered care for people with Caesarean Section and Normal Delivery. A cross-sectional study was conducted among 200 people who had caesarean section and normal delivery in Al-Zahra Teaching Hospital in Tabriz, north western Iran. Service quality was calculated using: Service Quality = 10 - (Importance × Performance) based on importance and performance of service quality aspects from the postpartum women's perspective.A hierarchical regression analysis was applied in two steps using the enter method to examine the associations between demographics and SQ scores. Data were analysed using the SPSS-17 software. "Confidentiality", "autonomy", "choice of care provider" and "communication" achieved scores at the highest level of quality; and "support group", "prompt attention", "prevention and early detection", "continuity of care", "dignity", "safety", "accessibility and "basic amenities" got service quality score less than eight. Statistically significant relationship was found between service quality score and continuity of care (P=0.008). A notable gap between the participants‟ expectations and what they have actually received in most aspects of provided care. So, there is an opportunityto improve the quality of delivered care.

To investigate the effect of lipopolysaccharides(LPS) extracted from Porphyromonas endodontalis(P.e) on the expression of CD14 in osteoblast. Under the condition with or without serum, MC3T3-E1 cells were stimulated with 10 μg/mL P.e-LPS for 24 hours, then the expression of CD14 was measured using flow cytometry; the membrane CD14 mRNA was detected at different time point (0, 1, 3, 6, 12, 24 h) by RT-PCR. Statistical analysis was performed using two-sample t test, one-way ANOVA and Dunnett t test with SPSS13.0 software package. Flow cytometry showed that CD14 protein increased after the stimulation of P.e-LPS for 24 h, while the non-serum group demonstrated more increase; the membrane CD14 mRNA level was up-regulated by 10 μg/mL P.e-LPS at 1 hour, and reached the maximum at 3 h and declined after 6 h. P.e-LPS can induce the expression of CD14 in osteoblast MC3T3-E1, which indicates that P.e-LPS may play an important role in osteoblast through CD14.

INTRODUCTION: The aim of this study was to identify factors associated with the prevalence of anterior open bite among five-year-old Brazilian children. METHODS: A cross-sectional study was undertaken using data from the National Survey of Oral Health (SB Brazil 2010). The outcome variable was anterior open bite classified as present or absent. The independent variables were classified by individual, sociodemographic and clinical factors. Data were analyzed through bivariate and multivariate analysis using SPSS statistical software (version 18.0) with a 95% level of significance. RESULTS: The prevalence of anterior open bite was 12.1%. Multivariate analysis showed that preschool children living in Southern Brazil had an increased chance of 1.8 more times of having anterior open bite (CI 95%: 1.16 - 3.02). Children identified with alterations in overjet had 14.6 times greater chances of having anterior open bite (CI 95%: 8.98 - 24.03). CONCLUSION: There was a significant association between anterior open bite and the region of Brazil where the children lived, the presence of altered overjet and the prevalence of posterior crossbite.

In this paper, three different statistical approaches were used to investigate short-term tracking of cardiorespiratory and performance-related physical fitness among adolescents. Data were obtained from the Oporto Growth, Health and Performance Study and comprised 1203 adolescents (549 girls) divided into two age cohorts (10-12 and 12-14 years) followed for three consecutive years, with annual assessment. Cardiorespiratory fitness was assessed with 1-mile run/walk test; 50-yard dash, standing long jump, handgrip, and shuttle run test were used to rate performance-related physical fitness. Tracking was expressed in three different ways: auto-correlations, multilevel modelling with crude and adjusted model (for biological maturation, body mass index, and physical activity), and Cohen's Kappa (κ) computed in IBM SPSS 20.0, HLM 7.01 and Longitudinal Data Analysis software, respectively. Tracking of physical fitness components was (1) moderate-to-high when described by auto-correlations; (2) low-to-moderate when crude and adjusted models were used; and (3) low according to Cohen's Kappa (κ). These results demonstrate that when describing tracking, different methods should be considered since they provide distinct and more comprehensive views about physical fitness stability patterns.

This study was performed to assess the clinical and radiographic success rates of a formocresol and zinc oxide eugenol (ZOE) primary molar root canal therapy (RCT) technique. The effects of this treatment on the permanent successors and on exfoliation times were also investigated. Study design: the retrospective study included 161 patients with 211 primary molars treated by RCT by a single operator in a private paediatric dental office in the Toronto area. Data were coded and entered into a Microsoft Excel database and analysis undertaken using SPSS software. Predominantly non-parametric tests were used to evaluate statistical differences (p < 0.05). A clinical success rate of 90% (190/211) and a radiographic success rate of 77.3% (136/176) were obtained. Following RCT in a primary molar, enamel defects were found in 6.8% (7/103) of premolars, all of which occurred in first premolars, and in patients treated at a mean age of 54.1 months (p < 0.005). Treated molars exfoliated on average 7.6 months sooner than contralateral teeth (p < 0.005). This formocresol and ZOE RCT is a viable treatment for necrotic primary molars and yielded very high clinical and acceptable radiographic success rates.
