Evaluation of bond strength of resin cements using different general-purpose statistical software packages for two-parameter Weibull statistics.

PubMed

Roos, Malgorzata; Stawarczyk, Bogna

2012-07-01

This study evaluated and compared Weibull parameters of resin bond strength values using six different general-purpose statistical software packages for two-parameter Weibull distribution. Two-hundred human teeth were randomly divided into 4 groups (n=50), prepared and bonded on dentin according to the manufacturers' instructions using the following resin cements: (i) Variolink (VAN, conventional resin cement), (ii) Panavia21 (PAN, conventional resin cement), (iii) RelyX Unicem (RXU, self-adhesive resin cement) and (iv) G-Cem (GCM, self-adhesive resin cement). Subsequently, all specimens were stored in water for 24h at 37°C. Shear bond strength was measured and the data were analyzed using Anderson-Darling goodness-of-fit (MINITAB 16) and two-parameter Weibull statistics with the following statistical software packages: Excel 2011, SPSS 19, MINITAB 16, R 2.12.1, SAS 9.1.3. and STATA 11.2 (p≤0.05). Additionally, the three-parameter Weibull was fitted using MNITAB 16. Two-parameter Weibull calculated with MINITAB and STATA can be compared using an omnibus test and using 95% CI. In SAS only 95% CI were directly obtained from the output. R provided no estimates of 95% CI. In both SAS and R the global comparison of the characteristic bond strength among groups is provided by means of the Weibull regression. EXCEL and SPSS provided no default information about 95% CI and no significance test for the comparison of Weibull parameters among the groups. In summary, conventional resin cement VAN showed the highest Weibull modulus and characteristic bond strength. There are discrepancies in the Weibull statistics depending on the software package and the estimation method. The information content in the default output provided by the software packages differs to very high extent. Copyright © 2012 Academy of Dental Materials. Published by Elsevier Ltd.

Longitudinal data analyses using linear mixed models in SPSS: concepts, procedures and illustrations.

PubMed

Shek, Daniel T L; Ma, Cecilia M S

2011-01-05

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.

For 2 × 2 tables, Egon Pearson's N - 1 chi-squared statistic is theoretically more sound than Karl Pearson's chi-squared statistic, and provides more accurate p values. Moreover, Egon Pearson's N - 1 chi-squared statistic is equal to the Mantel-Haenszel chi-squared statistic for a single 2 × 2 table, and as such, is often available in statistical software packages like SPSS, SAS, Stata, or R, which facilitates compliance with Ian Campbell's recommendations.

An SPSS implementation of the nonrecursive outlier deletion procedure with shifting z score criterion (Van Selst & Jolicoeur, 1994).

PubMed

Thompson, Glenn L

2006-05-01

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).

Multi-response permutation procedure as an alternative to the analysis of variance: an SPSS implementation.

PubMed

Cai, Li

2006-02-01

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.

2015-03-01

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.

SPSS and SAS programs for determining the number of components using parallel analysis and velicer's MAP test.

O'Connor, B P

2000-08-01

Popular statistical software packages do not have the proper procedures for determining the number of components in factor and principal components analyses. Parallel analysis and Velicer's minimum average partial (MAP) test are validated procedures, recommended widely by statisticians. However, many researchers continue to use alternative, simpler, but flawed procedures, such as the eigenvalues-greater-than-one rule. Use of the proper procedures might be increased if these procedures could be conducted within familiar software environments. This paper describes brief and efficient programs for using SPSS and SAS to conduct parallel analyses and the MAP test.

Analysis of longitudinal data from animals with missing values using SPSS.

PubMed

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.

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.

2012-01-01

Analysis of clinical studies often necessitates multiple graphical representations of the results. Many professional software packages are available for this purpose. Most packages are either only commercially available or hard to use especially if one aims to generate or customize a huge number of similar graphical outputs. We developed a new, freely available software tool called KMWin (Kaplan-Meier for Windows) facilitating Kaplan-Meier survival time analysis. KMWin is based on the statistical software environment R and provides an easy to use graphical interface. Survival time data can be supplied as SPSS (sav), SAS export (xpt) or text file (dat), which is also a common export format of other applications such as Excel. Figures can directly be exported in any graphical file format supported by R. On the basis of a working example, we demonstrate how to use KMWin and present its main functions. We show how to control the interface, customize the graphical output, and analyse survival time data. A number of comparisons are performed between KMWin and SPSS regarding graphical output, statistical output, data management and development. Although the general functionality of SPSS is larger, KMWin comprises a number of features useful for survival time analysis in clinical trials and other applications. These are for example number of cases and number of cases under risk within the figure or provision of a queue system for repetitive analyses of updated data sets. Moreover, major adjustments of graphical settings can be performed easily on a single window. We conclude that our tool is well suited and convenient for repetitive analyses of survival time data. It can be used by non-statisticians and provides often used functions as well as functions which are not supplied by standard software packages. The software is routinely applied in several clinical study groups.

2013-03-01

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.

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

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.

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.

To assess whether using ALAnerv® contributes to improvements of outcomes obtained in post SCI patients. A prospective controlled clinical survey also to evaluate the safety and efficacy of ALAnerv® (2cps/ day for 28 days) in motor incomplete (AIS/ Frankel C) paraplegic subacute patients. 59 patients divided in study (treated with ALAnerv®) and control, groups. This survey's follow-up duration was of 28 days. Most of the studied patients were mid-aged (mean 43.75 years old) and respectively, men (64,29% in the study group; 58,06% in controls). We used descriptive statistics (functions: minimum, maximum, mean, median, standard deviation) and for related comparisons, parametric (Student t) and non-parametric (Mann-Whitney, Fisher's exact, chi-square) tests. The primary end-point: AIS motor values' evolution (P= 0.015 - Mann-Whitney), showed that patients treated with ALAnerv® - vs. controls - had a statistically significant better increase of such scores at discharge. Paraclinical parameters, mainly exploring systemic inflammatory status (secondary end-point): ESR dynamics (P=0.13) had no statistical significance; the plasma leucocytes number (P=0.018), the neutrophils' percentage (P=0.001) and fibrinogenemia (P= 0,017) proved in the treated group to have a statistically significant better evolution. We used "Statistical Package for Social Sciences" (SPSS). As there is actually no effective curative solution for the devastating pathology following SCI, any medical approach susceptible to bring even limited improvements, such as treatment with ALAnerv® seemed to have proven, is worth being surveyed, under strict circumstances of ethics and research methodology. Considering the necessity for more statistical power concerning primary, secondary end-points, and safety issues, as well, continuing this research is needed.

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.

The widespread availability of statistical packages has undoubtedly helped hematologists worldwide in the analysis of their data, but has also led to the inappropriate use of statistical methods. In this article, we review some basic concepts of survival analysis and also make recommendations about how and when to perform each particular test using SPSS, Stata and R. In particular, we describe a simple way of defining cut-off points for continuous variables and the appropriate and inappropriate uses of the Kaplan-Meier method and Cox proportional hazard regression models. We also provide practical advice on how to check the proportional hazards assumption and briefly review the role of relative survival and multiple imputation. PMID:25176982

2011-01-01

This retrospective study evaluated the risk factors for persistent gestational trophoblastic disease (GTN) and determined their odds ratios. This study included 100 cases with GTN admitted to our clinic. Possible risk factors recorded were age, gravidity, parity, size of the neoplasia, and beta-human chorionic gonadotropin levels (beta-hCG) before and after the procedure. Statistical analyses consisted of the independent sample t-test and logistic regression using the statistical package SPSS ver. 15.0 for Windows (SPSS, Chicago, IL, USA). Twenty of the cases had persistent GTN, and the differences between these and the others cases were evaluated. The size of the neoplasia and histopathological type of GTN had no statistical relationship with persistence, whereas age, gravidity, and beta-hCG levels were significant risk factors for persistent GTN (p < 0.05). The odds ratios (95% confidence interval (CI)) for age, gravidity, and pre- and post-evacuation beta-hCG levels determined using logistic regression were 4.678 (0.97-22.44), 7.315 (1.16-46.16), 2.637 (1.41-4.94), and 2.339 (1.52-3.60), respectively. Patient age, gravidity, and beta-hCG levels were risk factors for persistent GTN, whereas the size of the neoplasia and histopathological type of GTN were not significant risk factors.

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.

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.

SOCR: Statistics Online Computational Resource

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.

Testing of therapies for disease or injury often involves analysis of longitudinal data from animals. Modern analytical methods have advantages over conventional methods (particularly where some data are missing) yet are not used widely by pre-clinical researchers. We provide here an easy to use protocol for analysing longitudinal data from animals and present a click-by-click guide for performing suitable analyses using the statistical package SPSS. We guide readers through analysis of a real-life data set obtained when testing a therapy for brain injury (stroke) in elderly rats. We show that repeated measures analysis of covariance failed to detect a treatment effect when a few data points were missing (due to animal drop-out) whereas analysis using an alternative method detected a beneficial effect of treatment; specifically, we demonstrate the superiority of linear models (with various covariance structures) analysed using Restricted Maximum Likelihood estimation (to include all available data). This protocol takes two hours to follow. PMID:27196723

Context: A study on odontogenic cysts and tumors. Aims: The aim of this study is to determine the frequency of odontogenic cysts and tumors and their distribution according to age, gender, site and histopathologic types of those reported over a period of 1998–2012 in a Tertiary Health Care Center at South Kerala. Settings and Design: The archives of Department of Oral Pathology and Microbiology, were retrospectively analyzed. Subjects and Methods: Archival records were reviewed and all the cases of odontogenic cysts and tumors were retrieved from 1998 to 2012. Statistical Analysis Used: Descriptive statistical analysis was performed using the computer software, Statistical Package for Social Sciences (SPSS) IBM SPSS Software version 16. Results: Of 7117 oral biopsies, 4.29% were odontogenic tumors. Ameloblastoma was the most common odontogenic tumor comprising 50.2% of cases, followed by keratocystic odontogenic tumor (24.3%). These tumors showed a male predilection (1.19: 1). Odontogenic tumors occurred in a mean age of 33.7 ± 16.8 years. Mandible was the most common jaw affected (76.07%). Odontogenic cysts constituted 12.25% of all oral biopsies. Radicular cyst comprised 75.11% of odontogenic cysts followed by dentigerous cyst (17.2%). Conclusions: This study showed similar as well as contradictory results compared to other studies, probably due to geographical and ethnic variations which is yet to be corroborated. PMID:27601809

To evaluate the effect of audioanalgesia in 6- to 12-year-old children during dental treatment procedure. A total of 40 children were selected and divided into two groups, study group - with audioanalgesia and control group - without audioanalgesia. The value of their pain was evaluated using Venham's pain rating scale. Data were compared using one-sample t-test using Statistical Package for the Social Sciences (SPSS) (Inc.; Chicago, IL, USA), version 17.0. The difference in the control group and study group was statistically significant (p < 0.05). The method of distraction using audioanalgesia instills better positive dental attitude in children and decreases their pain perception. Playing or hearing music during dental procedure significantly alters the perception of pain in 6- to 12-year-old children.

The objective of the present investigation is to evaluate patients' pain perception and discomfort, the duration of pain and the level of self-medication over time during tooth separation, and the effectiveness of elastomeric and spring types of orthodontic separators in Saudi population. The study group consisted of 30 female adolescent patients who had elastomeric/spring separators as part of their orthodontic treatment. A self-administrated questionnaire comprising 16 multiple choice questions and another with visual analog scale were used to record the patient's pain perceptions at 4 hours, 24 hours, 3 days, 5 days, and 7 days from the time of insertion. The level of pain and discomfort during these time periods were assessed by a visual analog scale. After a separation period of 7 days, the amount of separation was measured with a leaf gauge. Type and frequency of analgesic consumption was also recorded. The Statistical Package for the Social Sciences (SPSS) version 20 (IBM SPSS -Chicago, IL: SPSS Inc.,) was used for statistical analysis. The data showed significant increase in the level of pain at 4 hours, 24 hours, and 3 days from separator placement. The elastomeric separators produced significantly more separation than the spring separators and also caused maximum pain during the first 3 days after insertion. However, there was no significant difference between the score of pain between two separators at all time intervals. Both elastomeric and spring separators showed comparative levels of pain and discomfort during the early phase of separation. Elastomeric separators were found to be more effective in tooth separation than spring separators. However, further studies are necessary to substantiate this preliminary observation.

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.

Statistical models using multiple linear regression are some of the most widely used methods to study the influence of independent variables in a given phenomenon. This study's objective is to understand the influence of the various components of aerogel-based renders on their thermal and mechanical performance, namely cement (three types), fly ash, aerial lime, silica sand, expanded clay, type of aerogel, expanded cork granules, expanded perlite, air entrainers, resins (two types), and rheological agent. The statistical analysis was performed using SPSS (Statistical Package for Social Sciences), based on 85 mortar mixes produced in the laboratory and on their values of thermal conductivity and compressive strength obtained using tests in small-scale samples. The results showed that aerial lime assumes the main role in improving the thermal conductivity of the mortars. Aerogel type, fly ash, expanded perlite and air entrainers are also relevant components for a good thermal conductivity. Expanded clay can improve the mechanical behavior and aerogel has the opposite effect.

Objective: To evaluate for the presence of connective tissue growth factor (CTGF) in drug (phenytoin, cyclosporine, and nifedipine)-induced gingival overgrowth (DIGO) and to compare it with healthy controls in the absence of overgrowth. Materials and Methods: Thirty-five patients were chosen for the study and segregated into study (25) and control groups (10). The study group consisted of phenytoin-induced (10), cyclosporine-induced (10), and nifedipine-induced (5) gingival overgrowth. After completing necessary medical evaluations, biopsy was done. The tissue samples were fixed in 10% formalin and then immunohistochemically evaluated for the presence of CTGF. The statistical analysis of the values was done using statistical package SPSS PC+ (Statistical Package for the Social Sciences, version 4.01). Results: The outcome of immunohistochemistry shows that DIGO samples express more CTGF than control group and phenytoin expresses more CTGF followed by nifedipine and cyclosporine. Conclusion: The study shows that there is an increase in the levels of CTGF in patients with DIGO in comparison to the control group without any gingival overgrowth. In the study, we compared the levels of CTGF in DIGO induced by three most commonly used drugs phenytoin, cyclosporine, and nifedipine. By comparing the levels of CTGF, we find that cyclosporine induces the production of least amount of CTGF. Therefore, it might be a more viable drug choice with reduced side effects. PMID:29629324

Zakaria, Normah; Yamin, Azlin; Maarof, Rosmawati

2017-08-01

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.

2012-09-01

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.

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

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.

S2O - A software tool for integrating research data from general purpose statistic software into electronic data capture systems.

PubMed

Bruland, Philipp; Dugas, Martin

2017-01-07

Data capture for clinical registries or pilot studies is often performed in spreadsheet-based applications like Microsoft Excel or IBM SPSS. Usually, data is transferred into statistic software, such as SAS, R or IBM SPSS Statistics, for analyses afterwards. Spreadsheet-based solutions suffer from several drawbacks: It is generally not possible to ensure a sufficient right and role management; it is not traced who has changed data when and why. Therefore, such systems are not able to comply with regulatory requirements for electronic data capture in clinical trials. In contrast, Electronic Data Capture (EDC) software enables a reliable, secure and auditable collection of data. In this regard, most EDC vendors support the CDISC ODM standard to define, communicate and archive clinical trial meta- and patient data. Advantages of EDC systems are support for multi-user and multicenter clinical trials as well as auditable data. Migration from spreadsheet based data collection to EDC systems is labor-intensive and time-consuming at present. Hence, the objectives of this research work are to develop a mapping model and implement a converter between the IBM SPSS and CDISC ODM standard and to evaluate this approach regarding syntactic and semantic correctness. A mapping model between IBM SPSS and CDISC ODM data structures was developed. SPSS variables and patient values can be mapped and converted into ODM. Statistical and display attributes from SPSS are not corresponding to any ODM elements; study related ODM elements are not available in SPSS. The S2O converting tool was implemented as command-line-tool using the SPSS internal Java plugin. Syntactic and semantic correctness was validated with different ODM tools and reverse transformation from ODM into SPSS format. Clinical data values were also successfully transformed into the ODM structure. Transformation between the spreadsheet format IBM SPSS and the ODM standard for definition and exchange of trial data is feasible. S2O facilitates migration from Excel- or SPSS-based data collections towards reliable EDC systems. Thereby, advantages of EDC systems like reliable software architecture for secure and traceable data collection and particularly compliance with regulatory requirements are achievable.

2010-12-01

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.

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

Acne vulgaris is known to impair many aspects of the quality of life (QoL) of its patients. To translate the Cardiff Acne Disability Index (CADI) from English into Hindi and to assess its validity and reliability in Hindi speaking patients with acne from India. Hindi version of CADI, translated and linguistically validated as per published international guidelines, along with a previously translated Hindi version of dermatology life quality index (DLQI) and a demographic questionnaire were administered to acne patients. The internal consistency reliability of the Hindi version of CADI and its concurrent validity were assessed by Cronbach's alpha co-efficient and Spearman's correlation co-efficient respectively. Construct validity was examined by factor analysis. Statistical analysis was carried out using the Statistical Package for the Social Sciences (SPSS) version 20 (SPSS Inc., Chicago, IL, USA) for Windows. One hundred Hindi speaking patients with various grades of acne participated in the study. Hindi version of CADI showed high internal consistency reliability (Cronbach's alpha co-efficient = 0.722). Mean item-to-total correlation co-efficient ranged from 0.502 to 0.760. Concurrent validity of the scale was supported by a significant correlation with the Hindi DLQI. Factor analysis revealed the presence of two dimensions underlying the factor structure of the scale. Hindi CADI is equivalent to the original English version and constitutes a reliable and valid tool for clinical assessment of the impact of acne on QoL.

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.

During a two month period, the authors gathered data from patients who visited an emergency ward due to acute intoxication by a household product, and they compared the care which those patients required with the other patients suffering from different intoxications. The variables were introduced and analyzed using a SPSS 75.0 statistics package. The emergency ward registered 281 intoxication incidents of which 22 or 8.7% were related to household products. Among the conclusions drawn from this study the authors emphasize that the majority of patients intoxicated by household products were women. Caustic products are involved in the greatest number of incidences, either accidentally swallowed, splashed into eyes or inhaled as gas. The amount of treatment those patients require is less than the treatment required for other intoxications. Their prognostic is good.

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.

To determine the relationship between the frequency of work-related stress and prevalence of functional dyspepsia in a sample of 218 military older 50 years in 2010 in Lima Military Hospital Geriatric. Descriptive and explanatory study and for the data collection on stress, were used the Vital Events Scale Holmes-Rahe and clinical records for clinical and upper endoscopy registration that comply the criteria of Rome III for functional dyspepsia. For processing and data analysis the statistical software package SPSS (Statistical Package for Social Sciences) was used. 100% of military showed some level of work stress during the study year; thus, 36.7% had a high level, 31.2% medium or moderate level, and 32.1% had low stress level; these percentages medium and high stress levels accounted for 67.9%. These results establish that job stress is a common discomfort in the study population (tabulated Chi2 = 3.841, chi2 observed = 27,908). Regarding functional dyspepsia prevalence of 37.2%, which indicates that it is a common condition in those military (tabular Z = 1.96, Z c = 9.163) it was determined. There is a significant relationship between the frequency of work-related stress and prevalence of functional dyspepsia in military activity in older than 50 years (tabulated Chi2 = 5.991, chi2 observed = 28,878, contingency coefficient = 0.342).

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.

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

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.

Increasing population, fast paced industrialization, increased, competitiveness, unanticipated problems in the work place have increased the stress among the females working in health care in recent times. The aim of the following study is to detect the stress levels among female health care professionals in the age group of 25-35 years and its impact on health. A prospective cross-sectional pilot project was conducted in a tertiary care hospital in Eastern part of India, after receiving approval from the Institutional Ethics Committee and informed consent form was taken from the subjects. Stress level in the subjects was assessed according to the presumptive life event stress scale. Females with scores above 200 were selected. For these, initial assessment of anthropometric measurement, electrocardiogram and lipid profile analysis, resting pulse rate, blood pressure, physical fitness index (PFI), breath holding time (BHT), isometric hand grip (IHG) test results were evaluated and recorded. All subjects were given training of progressive muscle relaxation (PMR) for 3 months. After 3 months, the lipid profile and vital parameters, Perceived Stress Scale values were re-evaluated and subjects were asked to repeat the same exercises and data thus recorded were analyzed using Statistical Package for the Social Sciences (SPSS) version 16 (SPSS Inc. Released 2007. SPSS for Windows, Version 16.0. Chicago, SPSS Inc.). Significant decrease in resting heart rate, blood pressure and Perceived Stress Scale levels was seen after PMR training in the subjects. Results of BHT, IHG tests and PFI were significantly increased after PMR training. There was a significant decrease in total cholesterol, triglyceride and low-density lipoprotein cholesterol in subjects after practicing PMR for 3 months. Increasing stress among female health care professionals is a cause for concern and there is a need to adopt early life-style modification by practicing relaxation exercises to ameliorate stress and to improve not only their quality-of-life in general, but patient care in particular.

Background and aim Dental fear and anxiety is a major barrier for dental care provision. Identifying anxious patients can help dental professionals manage them appropriately. The study aimed at assessing dental fear and anxiety among a deaf population in Cluj-Napoca, Romania and their associated and contributing factors. Method In this cross sectional study 165 deaf participants were invited to complete a questionnaire comprising three sections. The first section contained questions about social and economical status, the second comprised a Romanian version of the Modified Dental Anxiety Scale (MDAS) while part three was the Dental Fear Survey (DFS). Data was introduced and analyzed with the Statistical Package for Social Sciences (SPSS) program, version 20.0 (SPSS Inc., Chicago, Illinois, USA). Results Thirty four point nine percent (34.9%) of respondents were found to be insignificantly anxious, 59.7% were moderately or extremely anxious with 5.3% being identified with dental phobia based on the MDAS scores. Mean total score for dental anxiety on the MDAS scale was 13.7. Patients suffering from a prior negative experience were found to be more anxious (p<0.05). Conclusions Dental fear and anxiety is widespread in the deaf communities. Higher percentages were observed among women and people with a previous traumatic dental experience. PMID:27004038

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 determine if the fibrinogen/C-reactive protein (CRP) ratio could be used in obstetrics as a predictor for a disseminated intravascular coagulation. One hundred eleven patients with hemolysis, elevated liver enzymes, and low platelet count syndrome at the Department of Obstetrics and Fetomaternal Medicine (General Hospital, Vienna, Austria) were selected and divided into 2 groups (overt disseminated intravascular coagulation, no overt disseminated intravascular coagulation). The classical parameters and the fibrinogen/CRP ratio were compared. The analysis was carried out using IBM SPSS statistical package (SPSS, Inc, Cary, NC). The fibrinogen/CRP ratio showed significant differences. The receiver-operating characteristic analysis showed for the ratio (area under the curve, 0.74) significantly better discriminative power than for fibrinogen (area under curve, 0.59). The odds ratio for the fibrinogen/CRP ratio was 7.04. Finally, significant correlations between the ratio and the neonatal outcome were found. We suggest the implementation of the fibrinogen/CRP ratio within patients with hemolysis, elevated liver enzymes, and low platelet count syndrome as a diagnostic and prognostic factor for the occurrence of disseminated intravascular coagulation.

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.

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.

Health warning labels on cigarette packages are among the most straightforward and important tools to communicate with smokers and various studies have illustrated their efficacy. The current study aimed to investigate the opinions of male smokers in Mashhad city about the efficacy of health warning labels printed on cigarette packages on the smoking status of smokers. This cross-sectional descriptive study was conducted in 2013 using a questionnaire. The research population included the male smokers of Mashhad. The participants were selected from the customers referring to the newsstands for cigarettes. The obtained data were analyzed employing SPSS software Version 16, and the statistical tests including Kruskal-Wallis, Spearman, and correlation coefficient of Pearson, Chi Square, Mann-Whitney, and Bonferroni correction were used in this regard. In this research, there were 500 participants with the average age of 25 years. The initiation age of smoking was eight years while the maximum age was reported as 45 years. Results of this research about the effect of these labels on decreasing cigarette consumption rate showed that almost half of the participants believed that these labels were ineffective for them (52.2%) and other smokers (53.8%).Furthermore, significant relationship was found between the age and opinion of the smokers about the influence of these labels on reducing their cigarette consumption (P < 0.001). To promote the effect of printed images on cigarette packages, it is recommended to consider the suitability of labels in the targeted culture. In addition, to be more effective consultation sites to quit smoking should be introduced under the images.

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

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

Chronic Sinusitis, an extremely persistent illness, is surgically best treated by Functional Endoscopic Sinus Surgery. The ostiomeatal complex is the main area targeted and within it uncinate process is the first anatomical structure encountered. The significance of anatomical variations concerning age and sex of uncinate process in chronic sinusitis were evaluated. A prospective study on 50 patients of chronic sinusitis (100 uncinate processes) was done. The results were tabulated and analyzed using Statistical Package for Social Science (SPSS) 16.0. Type I superior attachment of uncinate process (67 %) was the most common variety in all ages and both sexes and a statistically significant relationship between Type I superior attachment of uncinate process and sex was found (p < 0.05). The typical uncinate process was most common (70 %) followed by medial deviation of the uncinate (24 %). This difference in occurrence was significant with respect to both age and sex (p < 0.05). Anatomical variations of uncinate process are not responsible for causing chronic sinusitis. Mere presence of these variations of uncinate is not an indication for FESS.

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

Pseudomonas aeruginosa is a common opportunistic pathogen of humans among the Gram-negative bacilli. Clinically, it is associated with nosocomial infections like burns and surgical-site wound infections and remains a major health concern, especially among critically ill and immunocompromised patients. This is a prospective laboratory-based 2 year study conducted to isolate P. aeruginosa from wound specimens and the antimicrobial susceptibility pattern with reference to metallo-β-lactamase (MBL) production. Two hundred and twenty-four samples of P. aeruginosa isolated from wound specimens were included in the study. Antimicrobial susceptibility was done as per Clinical Laboratory Standard Institute (CLSI) guidelines. MBL-producing P. aeruginosa was detected using the EDTA disk diffusion synergy test. Statistical analysis was done using the SPSS 11 package (SPSS Inc., Chicago, IL). Out of the 224 P. aeruginosa isolates, 100% were susceptible to polymyxin B and colistin, 92·8% were sensitive to imipenem, 38% showed resistance to gentamicin followed by ceftazidime (31·69%) and meropenem (33·03). Sixteen (7·14%) isolates showed MBL production. Infection caused by drug-resistant P. aeruginosa is important to identify as it poses a therapeutic problem and is also a serious concern for infection control management. The acquired resistance genes can be horizontally transferred to other pathogens or commensals if aseptic procedures are not followed. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Background: Health warning labels on cigarette packages are among the most straightforward and important tools to communicate with smokers and various studies have illustrated their efficacy. Objectives: The current study aimed to investigate the opinions of male smokers in Mashhad city about the efficacy of health warning labels printed on cigarette packages on the smoking status of smokers. Patients and Methods: This cross-sectional descriptive study was conducted in 2013 using a questionnaire. The research population included the male smokers of Mashhad. The participants were selected from the customers referring to the newsstands for cigarettes. The obtained data were analyzed employing SPSS software Version 16, and the statistical tests including Kruskal-Wallis, Spearman, and correlation coefficient of Pearson, Chi Square, Mann-Whitney, and Bonferroni correction were used in this regard. Results: In this research, there were 500 participants with the average age of 25 years. The initiation age of smoking was eight years while the maximum age was reported as 45 years. Results of this research about the effect of these labels on decreasing cigarette consumption rate showed that almost half of the participants believed that these labels were ineffective for them (52.2%) and other smokers (53.8%).Furthermore, significant relationship was found between the age and opinion of the smokers about the influence of these labels on reducing their cigarette consumption (P < 0.001). Conclusions: To promote the effect of printed images on cigarette packages, it is recommended to consider the suitability of labels in the targeted culture. In addition, to be more effective consultation sites to quit smoking should be introduced under the images. PMID:24829777

2009-04-01

This study aim at the landslide susceptibility mapping within an area of the Daunia (Apulian Apennines, Italy) by a multivariate statistical method and data manipulation in a Geographical Information System (GIS) environment. Among the variety of existing statistical data analysis techniques, the logistic regression was chosen to produce a susceptibility map all over an area where small settlements are historically threatened by landslide phenomena. By logistic regression a best fitting between the presence or absence of landslide (dependent variable) and the set of independent variables is performed on the basis of a maximum likelihood criterion, bringing to the estimation of regression coefficients. The reliability of such analysis is therefore due to the ability to quantify the proneness to landslide occurrences by the probability level produced by the analysis. The inventory of dependent and independent variables were managed in a GIS, where geometric properties and attributes have been translated into raster cells in order to proceed with the logistic regression by means of SPSS (Statistical Package for the Social Sciences) package. A landslide inventory was used to produce the bivariate dependent variable whereas the independent set of variable concerned with slope, aspect, elevation, curvature, drained area, lithology and land use after their reductions to dummy variables. The effect of independent parameters on landslide occurrence was assessed by the corresponding coefficient in the logistic regression function, highlighting a major role played by the land use variable in determining occurrence and distribution of phenomena. Once the outcomes of the logistic regression are determined, data are re-introduced in the GIS to produce a map reporting the proneness to landslide as predicted level of probability. As validation of results and regression model a cell-by-cell comparison between the susceptibility map and the initial inventory of landslide events was performed and an agreement at 75% level achieved.

This study aims to identify the relationship between students' learning styles and mathematics anxiety amongst Form Four students in Kerian, Perak. The study involves 175 Form Four students as respondents. The instrument which is used to assess the students' learning styles and mathematic anxiety is adapted from the Grasha's Learning Styles Inventory and the Mathematics Anxiety Scale (MAS) respectively. The types of learning styles used are independent, avoidant, collaborative, dependent, competitive and participant. The collected data is processed by SPSS (Statistical Packages for Social Sciences 16.0). The data is analysed by using descriptive statistics and inferential statistics that include t-test and Pearson correlation. The results show that majority of the students adopt collaborative learning style and the students have moderate level of mathematics anxiety. Moreover, it is found that there is significant difference between learning style avoidant, collaborative, dependent and participant based on gender. Amongst all students' learning style, there exists a weak but significant correlation between avoidant, independent and participant learning style and mathematics anxiety. It is very important for the teachers need to be concerned about the effects of learning styles on mathematics anxiety. Therefore, the teachers should understand mathematics anxiety and implement suitable learning strategies in order for the students to overcome their mathematics anxiety.

Summary Aim Assess oral health, treatment needs and the correlation between tooth wear and medications in patients with psychiatric disease. Methodology 92 patients (40 male and 52 female) admitted in the Department of Neurology and Psychiatry of the Umberto I Hospital of Rome underwent an oral and dental clinical examination in accordance according to World Health Organization Basic Methods Criteria. One dentist performed all clinical examinations, training and calibration was carried out by an experienced clinical examiner. To measure the degree of inter-examiner agreement Kappa statistics was calculated. Level of tooth wear was assessed using the tooth wear classification of Johansson et al. Exact psychiatric pathology and medications of each patient were registrated. The Statistical Package for the Social Sciences (SPSS Inc., Chicago, Ill.) was used to analyze the data. A value of P < 0.05 was considered statistically significant. Results 34.78% of the sample regarding tooth wear demonstrated score 2. Men demonstrated 30% score 2, and 20% score 3 and 4 whereas female patients 38.46% score 2, 7.69% score 3 and none score 4. Conclusions Chronic exposure to neuroleptic drugs can cause phenomena of bruxism. There is a direct correlation between tooth wear, psychiatric disorders and administration of certain drugs. Poor oral hygiene and extensive unmet needs for dental treatment were widespread among psychiatric patients. PMID:25002918

GIS and statistical analysis for landslide susceptibility mapping in the Daunia area, Italy

Mancini, F.; Ceppi, C.; Ritrovato, G.

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.

This study aimed to assess the knowledge of puerperal mothers about the Guthrie test. A total of 75 mothers who sought primary care between October 2014 and February 2015 were investigated. The form was applied by the main researcher and the data was analyzed, using descriptive statistics with Microsoft Office Excel, and Statistical Package for Social Sciences (SPSS) programs. Association tests and statistical power were applied. Among the 75 mothers, 47 (62.7%) would have liked to receive more information about the newborn screening, especially regarding the correct sample collection period, followed by the screened morbidities. Most participants (n=55; 85.9%) took their children to be tested between the third and the seventh day of birth, as recommended by the Brazilian Health Ministry. Fifty-four women (72%) were unable to name the morbidities screened by the test in Minas Gerais, and they were also unaware that most have genetic etiology. The health professional who informed the mother about the Guthrie test was mainly the physician. This information was given prenatally to 57% of the cases, and to 43 % at the time of discharge from the hospital. The association test showed that mothers with higher education have more knowledge about the purpose and importance of the Guthrie test. The statistical power was 83.5%. Maternal knowledge about the Guthrie test is superficial and may reflect the health team's usual practice.

The primary aim of the following study is to estimate the chronological age based on the stages of third molar development following the eight stages (A to H) method of Demirjian et al. (along with two modifications-Orhan) and secondary aim is to compare third molar development with sex and age. The sample consisted of 115 orthopantomograms from South Indian subjects with known chronological age and gender. Multiple regression analysis was performed with chronological age as the dependable variable and third molar root development as independent variable. All the statistical analysis was performed using the SPSS 11.0 package (IBM ® Corporation). Statistically no significant differences were found in third molar development between males and females. Depending on the available number of wisdom teeth in an individual, R (2) varied for males from 0.21 to 0.48 and for females from 0.16 to 0.38. New equations were derived for estimating the chronological age. The chronological age of a South Indian individual between 14 and 22 years may be estimated based on the regression formulae. However, additional studies with a larger study population must be conducted to meet the need for population-based information on third molar development.

In today's highly competitive health care environment, many private health care settings are now looking into customer service indicators to learn customers' perceptions and determine whether they are meeting customers' expectations in order to ensure that their customers are satisfied with the services. This research paper aims to investigate whether the human elements were more important than the nonhuman elements in private health care settings. We used the internationally renowned SERVQUAL five-dimension model plus three additional dimensions-courtesy, communication, and understanding of customers of the human element-when evaluating health care services. A total of 191 respondents from three private health care settings in the Klang Valley region of Malaysia were investigated. Descriptive statistics were calculated by the Statistical Package for Social Sciences (SPSS) computer program, version 15. Interestingly, the results suggested that customers nowadays have very high expectations especially when it comes to the treatment they are receiving. Overall, the research indicated that the human elements were more important than the nonhuman element in private health care settings. Hospital management should look further to improve on areas that have been highlighted. Implications for management practice and directions for future research are discussed.

This study finds out drug usage trends in Stage I Hypertensive Patients without any compelling indications in Karachi, deviations of current practices from evidence based antihypertensive therapeutic guidelines and looks for cost minimization opportunities. In the present study conducted during June 2012 to August 2012, two sets were used. Randomized stratified independent surveys were conducted in doctors and general population - including patients, using pretested questionnaires. Sample sizes for doctors and general population were 100 and 400 respectively. Statistical analysis was conducted on Statistical Package for Social Science (SPSS). Financial impact was also analyzed. On the basis of patients' doctors' feedback, Beta Blockers, and Angiotensin Converting Enzyme Inhibitors were used more frequently than other drugs. Thiazides and low-priced generics were hardly prescribed. Beta blockers were prescribed widely and considered cost effective. This trend increases cost by two to ten times. Feedbacks showed that therapeutic guidelines were not followed by the doctors practicing in the community and hospitals in Karachi. Thiazide diuretics were hardly used. Beta blockers were widely prescribed. High priced market leaders or expensive branded generics were commonly prescribed. Therefore, there are great opportunities for cost minimization by using evidence-based clinically effective and safe medicines.

Specific health warning placed on the tobacco product packages is considered as an effective and low-cost method for increasing the knowledge and awareness among the community. Thus, a study was conducted to assess the perception of pictorial health warnings (PHWs) against smoking among the adult rural population of Sarawak. Cross-sectional data were collected from 10 villages in Kota Samarahan and Kuching Division by face to face interview using modified Global Adult Tobacco Survey questionnaire. Nonprobability sampling method was adopted to select the villages. All the households of the selected villages were visited and an adult member was selected randomly from each house irrespective of the sex. After missing value imputation, 1000 data were analysed using statistical software IBM SPSS 20.0 version. Analysis showed that 28.8% of the respondents were current smokers, 7.8% were past smokers and the rest were non-smokers. Six items of pictorial health warnings were evaluated with five point Likert's scales for attractiveness, fearfulness and adequacy of the information. Analysis revealed that the majority of the respondents had perceived awareness on PHWs, but the smokers believed that this was not adequate to make them quit smoking. Only one-fifth (19.7%) of them reported that current pictorial health warnings were sufficient to motivate people to quit smoking. Though the PHWs on cigarette packages are appealing, it is not sufficient as a reason to stop smoking. Thus, an approach using an integrated anti-tobacco public health programme should be focused into the specific targeted community.

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 purpose of this study was to compare the effects of Mulligan's tape (MT) and kinesio tape (KT) with no tape (NT) on hip and knee kinematics and kinetics during running. Twenty-nine female recreational runners performed a series of 'run-throughs' along a 10-m runway under the three taping conditions. Two force plates and a 14-camera Vicon motion analysis system (Oxford Metrics, Inc., Oxford, UK) captured kinematic and kinetic data for each dependent variable from ground contact to toe off. Comparisons of each dependent variable under three taping conditions were assessed through Statistical Package for the Social Sciences (SPSS; SPSS, Inc., Chicago, Illinois, USA; P-value < 0.01) using repeated measure analyses of variance. For each dependent variable with a P-value < 0.01, repeated measures with pairwise comparisons and Bonferroni adjustment were conducted to compare the three taping conditions. MT induced a significant reduction in anterior and posterior hip forces, knee flexion angular velocity, knee extensor moments, and hip flexion and extension moments compared with NT and KT (P = 0.001). There was no difference in hip or knee, kinematics or kinetics, between KT and NT (P = 1.000). MT appears to influence hip and knee biomechanics during running in an asymptomatic sample, whereas KT appeared to be biomechanically not different from NT. © 2014 John Wiley & Sons A/S.

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.

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.

Analysis of F-16 radar discrepancies

One hundred and eight aircraft were randomly selected from three USAF F-16 bases and examined. These aircraft included 63 single-seat F-16As and 45 two-seat F-16Bs and encompassed 8,525 sorties and 748 radar system write-ups. Programs supported by the Statistical Package for the Social Sciences (SPSS) were run on the data. Of the 748 discrepancies, over one-third of them occurred within three sorties of each other and half within six sorties. Sixteen percent of all aircraft which had a discrepancy within three sorties had another write-up within the next three sorties. Designated repeat/recurring write-ups represented one-third of all the instances in which the write-up separation interval was three sorties or less. This is an indication that maintenance is unable to correct equipment failures as they occur, most likely because the false alarm rate is too high and maintenance is unable to duplicate the error conditions on the ground for correct error diagnosis.

Many women have incorrect notions of what they can eat during pregnancy and/or breast-feeding, due to preconceived ideas or myths related with the ingestion of some types of food. The aim of this study was to evaluate the alteration of food habits in pregnant women and identifying the myths related with eating habits in pregnant and breast-feeding women. A questionnaire of food habits alteration in pregnant women, the origin of the alterations and the reasons for such, as well as the eventual knowledge about which food interferes with pregnancy and/or breast-feeding and the Information about the alteration of weight during pregnancy and relevant clinical history were asked. The data were analysed though SPSS (Statistical Package for the Social Sciences), version13.0 for Windows. This study shows that although the majority of the alterations of food eating habits were done in a proper manner, there are still many inadequate or unnecessary food habit changes done in an empirical form, or based on myths, or indicated by some health professionals.

The image of mathematics held by Irish post-primary students was examined and a model for the image found was constructed. Initially, a definition for 'image of mathematics' was adopted with image of mathematics hypothesized as comprising attitudes, beliefs, self-concept, motivation, emotions and past experiences of mathematics. Research focused on students studying ordinary level mathematics for the Irish Leaving Certificate examination - the final examination for students in second-level or post-primary education. Students were aged between 15 and 18 years. A questionnaire was constructed with both quantitative and qualitative aspects. The questionnaire survey was completed by 356 post-primary students. Responses were analysed quantitatively using Statistical Package for the Social Sciences (SPSS) and qualitatively using the constant comparative method of analysis and by reviewing individual responses. Findings provide an insight into Irish post-primary students' images of mathematics and offer a means for constructing a theoretical model of image of mathematics which could be beneficial for future research.

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

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.

Aim: Comparison between the objective refraction measurement results determined with Topcon KR-8900 standard autorefractometer and Plusoptix A09 photo-refractometer in children. Material and methods: A prospective transversal study was performed in the Department of Ophthalmology of "Sf. Spiridon" Hospital in Iași on 90 eyes of 45 pediatric patients, with a mean age of 8,82 ± 3,52 years, examined with noncycloplegic measurements provided by Plusoptix A09 and cycloplegic and noncycloplegic measurements provided by Topcon KR-8900 standard autorefractometer. The clinical parameters compared were the following: spherical equivalent (SE), spherical and cylindrical values, and cylinder axis. Astigmatism was recorded and evaluated with the cylindrical value on minus after transposition. The statistical calculation was performed with paired t-tests and Pearson's correlation analysis. All the data were analyzed with SPSS statistical package 19 (SPSS for Windows, Chicago, IL). Results: Plusoptix A09 noncycloplegic values were relatively equal between the eyes, with slightly lower values compared to noncycloplegic auto refractometry. Mean (± SD) measurements provided by Plusoptix AO9 were the following: spherical power 1.11 ± 1.52, cylindrical power 0.80 ± 0.80, and spherical equivalent 0.71 ± 1.39. The noncycloplegic auto refractometer mean (± SD) measurements were spherical power 1.12 ± 1.63, cylindrical power 0.79 ± 0,77 and spherical equivalent 0.71 ± 1.58. The cycloplegic auto refractometer mean (± SD) measurements were spherical power 2.08 ± 1.95, cylindrical power 0,82 ± 0.85 and spherical equivalent 1.68 ± 1.87. 32% of the eyes were hyperopic, 2.67% were myopic, 65.33% had astigmatism, and 30% eyes had amblyopia. Conclusions: Noncycloplegic objective refraction values were similar with those determined by autorefractometry. Plusoptix had an important role in the ophthalmological screening, but did not detect higher refractive errors, justifying the cycloplegic autorefractometry.

The purpose of this study is to analyze whether supplementation of general anesthesia (GA) with thoracic epidural analgesia (TEA) for right lobe donor hepatectomy is a safe modality of pain relief in terms of changes in postoperative coagulation profile, incidence of epidural catheter-related complications, and timing of removal of epidural catheter. Retrospective analysis of the record of 104 patients who received TEA for right lobe donor hepatectomy was done. Platelet count, international normalized ratio, alanine aminotransferase, and aspartate aminotransferase were recorded postoperatively until the removal of the epidural catheter. The day of removal of the epidural catheter and visual analogue scale (VAS) scores were also recorded. Any complication encountered was documented. Intraoperatively, central venous pressure (CVP), hemodynamic variables, and volume of intravenous fluids infused were also noted. Statistical analysis was performed by using SPSS statistical package, version 17.0 (SPSS Inc. Chicago, IL). Continuous variables were presented as mean ± standard deviation. A total of 90% of patients had mean VAS scores between 1 and 4 in the postoperative period between days 1 and 5. None of the patients had a VAS score above 5. Although changes in coagulation status were encountered in all patients in the postoperative period, these changes were transient and did not persist beyond postoperative day (POD) 5. There was no delay in removal of the epidural catheter, and the majority of patients had the catheter removed by POD 4. There was no incidence of epidural hematoma. Aside from good intraoperative and postoperative analgesia, TEA in combination with balanced GA and fluid restriction enabled maintenance of low CVP and prevention of hepatic congestion. In conclusion, vigilant use of TEA appears to be safe during donor hepatectomy. Living liver donors should not be denied efficient analgesia for the fear of complications.

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.

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.

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

Reliable medicine information is important not only for physicians and pharmacists, but also for patients [6]. However, the results of studies implemented in some countries show that patients may have slightly different needs and preferences in using sources of information [1, 4, 5, 7]. The main objective of patient medicines information is assisting consumers to achieve safe and effective use of pharmaceuticals [2, 3]. To identify patients' needs in medicine information and sources they use to receive it. We interviewed 1059 people who had visited community pharmacies in 10 regions of Armenia and Yerevan. Previously developed questionnaire was used for interviewing patients. Statistical analysis was conducted using SPSS program. We found that consumers need medicine information. 68.9% of respondents often use pharmaceuticals only if necessary medicines information is available. The majority of them believe that it is important to have information about therapeutic indications of pharmaceuticals to be used (91.8%), their dosage and method of administration (91.1%), contraindications (82.4%), adverse reactions (81.9%) and the simultaneous use of multiple medicines (76.5%). 58.9% of consumers value information about medicine's price. More than 70% of patients often seek information from health professionals and use medicines package information leaflets (PIL), and more than 75% of respondents mainly trust the same sources. 71.5% of respondents read package leaflets, while 42.0% of consumers do this several times. Only 36.7% of respondents completely understand information in a leaflet. Patients in Armenia need medicine information. They prefer to receive information from sources they trust.Many patients do not understand the content of package information leaflets (PILs) due to barriers, which can be removed by introducing appropriate regulatory provisions for their content and readability.

Aim: The primary aim of the following study is to estimate the chronological age based on the stages of third molar development following the eight stages (A to H) method of Demirjian et al. (along with two modifications-Orhan) and secondary aim is to compare third molar development with sex and age. Materials and Methods: The sample consisted of 115 orthopantomograms from South Indian subjects with known chronological age and gender. Multiple regression analysis was performed with chronological age as the dependable variable and third molar root development as independent variable. All the statistical analysis was performed using the SPSS 11.0 package (IBM ® Corporation). Results: Statistically no significant differences were found in third molar development between males and females. Depending on the available number of wisdom teeth in an individual, R2 varied for males from 0.21 to 0.48 and for females from 0.16 to 0.38. New equations were derived for estimating the chronological age. Conclusion: The chronological age of a South Indian individual between 14 and 22 years may be estimated based on the regression formulae. However, additional studies with a larger study population must be conducted to meet the need for population-based information on third molar development. PMID:26005306

The objectives of this study were to determine the anthropometric variables of children with sickle cell anaemia and comparing it with those with normal haemoglobin genotype. A cross sectional study of anthropometric measurements was conducted over a period of six months. Children with sickle cell anaemia in steady state aged between 6-20 years were recruited. Nutritional assessment was done using anthropometrical variables. Data were analyzed using the Statistical Package for Social Sciences program (SPSS), version 20. The sickle cell patients comprised of 20 males and 20 females. There were an equal number of controls with an equal male to female ratio of 1:1. Forty eight percent (19) of the children with sickle cell anemia were underweight (< 5th %ile) and this is statistically significant. χ(2)=18.02 and p=0.000. When compared with subjects with normal haemoglobin genotype only five of them (13%) were underweight. χ(2)=10.286 and p=0.001. The controls weighed significantly more than the HbSS patients and also had significantly larger body surface compared to the HbSS population (P<0.05). BMI and other anthropometric variables among children with sickle cell anemia were low when compared with children with normal Haemoglobin genotype.

There is limited information on injury patterns in Step Aerobic Instructors (SAI) who exclusively execute "step" aerobic classes. To record the type and the anatomical position in relation to diagnosis of muscular skeletal injuries in step aerobic instructors. Also, to analyse the days of absence due to chronic injury in relation to weekly working hours, height of the step platform, working experience and working surface and footwear during the step class. The Step Aerobic Instructors Injuries Questionnaire was developed, and then validity and reliability indices were calculated. 63 SAI completed the questionnaire. For the statistical analysis of the data, the method used was the analysis of frequencies, the non-parametric test χ^{2} (chi square distribution), correlation and linear and logistic regressions analysis from the SPSS statistical package. 63 SAI reported 115 injuries that required more than 2 days absence from step aerobic classes. The chronic lower extremity injuries were 73.5%, with the leg pain, the anterior knee pain, the plantar tendinopathy and the Achilles tendinopathy being most common overuse syndromes. The working hours, the platform height, the years of aerobic dance seem to affect the days of absence due to chronic lower limb injury occurrence in SAI.

Two occlusal splints, the full-arch stabilization splint and the anterior midline point stop (AMPS) device, were evaluated for their efficiency in relieving myogenous temporomandibular disorders (TMD). One hundred and fourteen patients with myogenous TMD were distributed into 3 groups. The first group was treated with the AMPS device, the second with the stabilization splint, and the third group was the control group. Pain intensity was scored using the visual analogue scale before treatment and 1 month and 3 months after treatment. Statistical Package for the Social Sciences (SPSS, Chicago, Ill) and multiple comparisons tests were used to compare results before and after treatment and to compare the groups. The use of AMPS device in the first group resulted in a significant improvement after 1 month and 3 months (P < or = .001) and showed a 56.66% pain reduction. A significant improvement was also noticed in the second group (P = .001) with a 47.71% pain reduction. Although pain reduction percentage appeared more in the first group, this was not statistically significant. There was a highly significant difference between groups treated with both kinds of splints and the control group. It was concluded that both types of occlusal splints are beneficial to patients with myogenous TMD.

The aim of this study was to systematically review scientific literature in orderto describe the characteristics and prognosis of malignant entities developing from odontogenic cysts. A search in Pubmed (MEDLINE) and Cochrane databases was conducted. The inclusion criteria were articles published in English related to the malignisation of odontogenic cysts in humans. The exclusion criteria were articles that do not specify the type of odontogenic cyst, malignisation of parakeratinised keratocysts, the presence of an ameloblastic carcinoma and metastasis from distant primary tumours. The selected articles were classified according to Strength of Recommendation Taxonomy criteria. Statistical analysis of the data was carried out using statistical package software SPSS version 22.0. From the 1,237 articles initially obtained, the authors included 3 case series and 45 case reports in the end. Descriptive analysis showed that men have a disposition for malignisation from odontogenic cysts and they frequently appear at the posterior mandible, with pain and swelling being the most frequent signs and symptoms. Follicular cysts were the entities that underwent the most malignant changes with well differentiated squamous cell carcinomas being the most prevalent type of malignancy. The real prognosis of this malignancy is not known because of the heterogeneity of available studies.

The age of an individual can be assessed by a plethora of widely available tooth-based techniques, among which radiological methods prevail. The Demirjian's technique of age assessment based on tooth development stages has been extensively investigated in different populations of the world. The present study is to assess the applicability of Demirjian's modified 8-teeth technique in age estimation of population of East India (Odisha), utilizing Acharya's Indian-specific cubic functions. One hundred and six pretreatment orthodontic radiographs of patients in an age group of 7-23 years with representation from both genders were assessed for eight left mandibular teeth and scored as per the Demirjian's 9-stage criteria for teeth development stages. Age was calculated on the basis of Acharya's Indian formula. Statistical analysis was performed to compare the estimated and actual age. All data were analyzed using SPSS 20.0 (SPSS Inc., Chicago, Illinois, USA) and MS Excel Package. The results revealed that the mean absolute error (MAE) in age estimation of the entire sample was 1.3 years with 50% of the cases having an error rate within ± 1 year. The MAE in males and females (7-16 years) was 1.8 and 1.5, respectively. Likewise, the MAE in males and females (16.1-23 years) was 1.1 and 1.3, respectively. The low error rate in estimating age justifies the application of this modified technique and Acharya's Indian formulas in the present East Indian population.

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

Background: Chronic infections in CHD are due to one or both of the organisms Chlamydia pneumoniae and Helicobacter pylori. Aim: To examine the association between serum markers of Chlamydia pneumoniae and Helicobacter pylori infection and markers of myocardial damage. in patients with acute coronary syndrome (ACS), with chronic coronary artery disease (CAD) and in–control group. Material and methods: Sera were taken from a total of 153 subjects. Subjects were divided in three groups: 64 patients with ACS; 53 patients with CAD and a group of 35 conditionally healthy individuals. Analysis of patients’ sera for IgG antibodies to H. pylori and markers for myocardial damage was done on the Immulite system. The presence of specific IgG and IgA antibodies to C. pneumoniae was determined with MIF, Sero FIA (Savyon Diagnostics, Israel). Statistical analysis of data was done using the statistical program SPSS (Statistical Package for Social Sciences), version 13. Results and discussion: There was a high significant difference in troponin levels between the three groups of subjects (p=0.0000). Levels of creatine kinase isoenzyme (CK-MB) were highest in the ACS group (500.0 ng/mL). There was a statistically significant difference between CG subjects and ACS patients due to more frequent detection of antichlamydial IgA antibodies in patients with acute coronary syndrome. Positive serum immune response for Helicobacter pylori was 17 (53.1%) and 29 (80.6%), respectively. Conclusion: Increased IgA antibody titers for C. Pneumoniae, increased CRP values as well as classic markers of myocardial damage are risk factors for coronary events. PMID:23922522

Background: A surface smear layer consisting of organic and inorganic material is formed on the root surface following mechanical instrumentation and may inhibit the formation of new connective tissue attachment to the root surface. Modification of the tooth surface by root conditioning has resulted in improved connective tissue attachment and has advanced the goal of reconstructive periodontal treatment. Aim: The aim of this study was to compare the effects of citric acid, tetracycline, and doxycycline on the instrumented periodontally involved root surfaces in vitro using a scanning electron microscope. Settings and Design: A total of 45 dentin samples obtained from 15 extracted, scaled, and root planed teeth were divided into three groups. Materials and Methods: The root conditioning agents were applied with cotton pellets using the Passive burnishing technique for 5 minutes. The samples were then examined by the scanning electron microscope. Statistical Analysis Used: The statistical analysis was carried out using Statistical Package for Social Sciences (SPSS Inc., Chicago, IL, version 15.0 for Windows). For all quantitative variables means and standard deviations were calculated and compared. For more than two groups ANOVA was applied. For multiple comparisons post hoc tests with Bonferroni correction was used. Results: Upon statistical analysis the root conditioning agents used in this study were found to be effective in removing the smear layer, uncovering and widening the dentin tubules and unmasking the dentin collagen matrix. Conclusion: Tetracycline HCl was found to be the best root conditioner among the three agents used. PMID:24744541

Limited health literacy among adults is one of the many barriers to better oral health outcomes. It is not uncommon to find people who consider understanding oral health information a challenge. Therefore, the present study assessed oral health literacy among clients visiting Gian Sagar Dental College and Hospital, Rajpura. A cross-sectional study was conducted on 450participants who visited the Out Patient Department (OPD) of Gian Sagar Dental College and Hospital for a period of two months (Nov-Dec, 2013). A questionnaire was given to each of the participants. Oral health literacy was graded on a 12-point Likert scale based on the total score. Oral Health Literacy of the participants was assessed as low, medium and high on the basis of responses. Statistical analysis was done using SPSS-15 statistical package. ANOVA and Student t-test were used to do comparisons between groups. Low oral health literacy scores were reported in 60.2% (271) participants. More than 60% of the study participants had knowledge about dental terms such as 'dental caries,' and 'oral cancer.' Only 22% of the graduates had a high literacy score. Mean oral health literacy score according to educational qualification was statistically significant (p<0.05), whereas there was no significant difference in terms of age and gender (p>0.05). The majority of the participants had low literacy scores. There is a need to address these problems especially among rural population by health care providers and the government.

College life involves a process of adaptation to changes that have an impact on the psycho-emotional development of students. Successful adaptation to this stage involves the balance between managing personal resources and potential stressors that generate distress. This epidemiological descriptive and transversal study estimates the prevalence of psychopathological symptomatology and psychological well-being among 516 college students, 378 (73.26%) women and 138 (26.74%) men, ages between 17 and 24, from the city of Monterrey in Mexico. It describes the relationship between psychopathological symptomatology and psychological well-being, and explores gender differences. For data collection, two measures were used: The Symptom Checklist Revised and the Scale of Psychological Well-being. Statistical analyses used were t test for independent samples, Pearson’s r and regression analysis with the Statistical Package for the Social Sciences (SPSS v21.0). Statistical analyses showed that the prevalence of psychopathological symptoms was 10–13%, being Aggression the highest. The dimension of psychological well-being with the lowest scores was Environmental Mastery. Participants with a higher level of psychological well-being had a lower level of psychopathological symptoms, which shows the importance of early identification and prevention. Gender differences were found on some subscales of the psychopathological symptomatology and of the psychological well-being measures. This study provides a basis for future research and development of resources to promote the psychological well-being and quality of life of university students. PMID:29104876

To compare the outcome after surgery for chronic subdural hematoma when the drain is placed in subdural space or subgaleal space. Quasi experimental study. Combined Military Hospital, Lahore, from July 2015 to June 2016. Patients with chronic subdural hematoma of both genders and age, ranging between 55 to 85 years, were included. Patients on antiplatelet/anticoagulant therapy and acute on chronic subdural hematoma were excluded. Patients were divided in two equal groups each depending on whether drain was placed in subgaleal space (Group 1), and subdual space (Group 2), (n=31 patients each). Patients were positioned flat in bed after surgery. Clinical and radiological parameters and clinical outcome were compared between the two groups. Statistical test with significance of p <0.05 was utilized using Statistical Package of Social Sciences (SPSS version 17). Median age of the 62 patients was 72 ±12.5 years. Headache was the most common symptom reported in both groups, (n=47,75.8%) patients. Median thickness of hematoma was 15 ±6.5 mm. Patients with subdural drain placement had more complications such as pneumocephalus 11 (35.4%) vs. 6 (19.3%), and intracerebral hemorrhage 4 (12.9%) vs. 2 (6.4%). Clinical outcome was good in both groups 27 (87%) in Group 1 and 28 (90%) in Group 2. Patients of both groups had good outcome after surgery. Complications like pneumocephalus and intracerebral hemorrhage were more common in subdural location of drain, though not reaching statistically significance level to favor one technique over another.

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

This study aims at identifying predictors of asymptomatic bacteriuria (AB) among pregnant women in a low-resource setting, with the intent of recommending a guideline for screening during antenatal care. A total of 266 healthy pregnant women were antenatally recruited after informed consent. 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.

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.

The success and quality of postgraduate education depends largely on the effective and efficient supervision of postgraduate students. The role of the supervisor becomes more challenging with supervisory expectations rising high quality graduates. The main objective of this study was to examine the experiences of postgraduate students towards supervisory services for the duration of their studies. It also examines whether supervisory experience varies based on demographic variables such as level of study and nationality. This study uses a quantitative approach in the form of survey. Questionnaires were distributed to 96 postgraduate students of the Faculty of Information Science and Technology, Universiti Kebangsaan Malaysia. Data collected were analyzed using Statistical Package for the Social Science (SPSS 23.0) to get the frequency, mean and standard deviation. T-test was used to find the difference between demographic variables and supervisory experience. The findings overall showed that postgraduate students gave positive response to the supervisory services. However, there were differences supervisory experiences based on the level of study and nationality. The results of this study hope the parties involved could provide a better support to improve the quality of supervision.

To determine the frequency of altered findings on repeat cranial tomography (CT) in patients with mild head injury along with stable neurological examination at tertiary care hospital. Cross-sectional study was done in the Department of Radiology, Liaquat National Hospital, Karachi from January 2008 to September 2010. All patients with mild head injury in terms of Glasgow Coma Scale (GCS) who underwent repeat scan without clinical or neurological deterioration in the emergency department of a tertiary care centre were included. The collected data were accordingly entered and analyzed by the principal investigator using Statistical Package for Social Sciences (SPSS) version 16.0. In all 275 patients, only 17 (6%) of the patients were found worseing on repeat CT, 120 (43.63%) scans improved, 138 (50.18%) unchanged and 17 (6.18%) worsened. None of these patients showed signs of clinical deterioration. Our results suggest that for patients with mild head injury and stable neurological examination, only 6% of them show deterioration on repeat CT, especially when patients'GCS is below 13.

This study aimed to analyze the perceptions of users of the Brazilian Unified Health System (SUS) about the treatment Center where they were assisted, as well as about the speech-language pathology services rendered by this Center. This is a transversal study composed of an interview with 26 open questions and 14 closed questions applied to 111 individuals who were assisted at the SUS Center in August 2013. The quantitative content analysis was conducted through the use of the GraphPadPrisma 5.1, Statistic Package for Social Sciences (SPSS) 15.0 software and the application of the D'agostino & Person, F-test and chi-squared test. Most participants reported a positive perception about the facilities and staff of the treatment center. They were also positive about the waiting time and the speech-language pathologists' explanations and conduct, especially in the audiology department. Most responses from participants were short and did not present an argumentative context. The treatment center received a high approval rating by most users. The audiology department had better grades than the clinical services related to language and oral motor pathologies.

Palmer, Joel C.

The purpose of this study was to examine the impact of planetarium experiences on students' understanding of phases of the moon and eclipses. This research employed a quasi-experimental design. Students from 12 classes in four different schools all in the same school district participated in the study. A total of 178 students from four teachers participated in the study. Data were collected using a researcher developed pretest and posttest. All students received classroom instruction based on the school district's curriculum. The experimental groups took the posttest after attending a 45-minute planetarium experience titled Moon Witch. The control groups took the posttest before attending the planetarium experience but after receiving an additional 45-minute lesson on phases of the moon and eclipses. The data were analyzed using the Statistical Package for Social Sciences (SPSS). An Analysis of Variance (ANOVA) was run to determine if there was variance among teachers' instructional practices. Since the results indicated there was no significant variance among teachers, the study sample was analyzed as a single group. An Independent Samples t Test for Means was run in SPSS for the study sample and each subgroup. Subgroups were African American, Hispanic, White, Male, Female, and Economically Disadvantaged. The results indicated that there was an improvement on mean gain scores for the experimental group over the control group for all students and each subgroup. The differences in mean gain scores were significantly higher for all students and for the African American, Female, and Economically Disadvantaged subgroups. An Independent Samples t Test for Means was run using SPSS for each of the three different sections of the pretest and posttest. The results indicated that most of the improvement was in Section 3. This section required students to manipulate photos of the phases of moon into correct order. This section required more spatial reasoning than Section 1, multiple-choice, or Section 2, essay. Results indicate that planetarium experiences improved students' understanding of phases of the moon and eclipses. There was evidence that this improvement was facilitated by the planetarium's ability to create visual representations that students would otherwise have to create mentally.

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.

Malaysian government’s aim to include nuclear energy for electricity generation has triggered various reactions from all especially the public. The objective of this study is to have a better understanding on the knowledge, sources of information of nuclear power and sources of energy chosen by Malaysian in 20 years’ time. Besides that, we want to examine the level of acceptance and perception of Malaysian towards nuclear energy and we want to identify the correlation between public perceptions with the acceptance towards nuclear power in Malaysia, and also to study the differences between perception and acceptance of nuclear power with gender and educational level. For this research methodology, the research questions are given orally or through paper-pencil and also social networking site such as Facebook or through electronic media application such as WhatsApp and Google docs. The data were analysed using a SPSS version 22.0 (Statistical Package for the Social Sciences). Results showed that more than 50% of the respondents have the knowledge of nuclear energy. A part of from that, only 39 % are confident government can afford to build NPP in Malaysia and 41 % disagree nuclear energy is the best option for future energy. From analysis using SPSS 22 we estimate negative perception will give a negative acceptance in term of support towards the use of nuclear energy in power generation in Malaysia. There are also slight correlation that the higher the level of education of Malaysian, the more negative the perception of Malaysian in accepting nuclear energy as source of power in Malaysia. Therefore in shaping a positive acceptance of NPP in Malaysia, the authorities need to educate the people with the knowledge of nuclear in order to overcome the negative perception towards nuclear power.

PubMed Central

Dziadkowiec, Oliwier; Callahan, Tiffany; Ozkaynak, Mustafa; Reeder, Blaine; Welton, John

2016-01-01

Objectives: We examine the following: (1) the appropriateness of using a data quality (DQ) framework developed for relational databases as a data-cleaning tool for a data set extracted from two EPIC databases, and (2) the differences in statistical parameter estimates on a data set cleaned with the DQ framework and data set not cleaned with the DQ framework. Background: The use of data contained within electronic health records (EHRs) has the potential to open doors for a new wave of innovative research. Without adequate preparation of such large data sets for analysis, the results might be erroneous, which might affect clinical decision-making or the results of Comparative Effectives Research studies. Methods: Two emergency department (ED) data sets extracted from EPIC databases (adult ED and children ED) were used as examples for examining the five concepts of DQ based on a DQ assessment framework designed for EHR databases. The first data set contained 70,061 visits; and the second data set contained 2,815,550 visits. SPSS Syntax examples as well as step-by-step instructions of how to apply the five key DQ concepts these EHR database extracts are provided. Conclusions: SPSS Syntax to address each of the DQ concepts proposed by Kahn et al. (2012)1 was developed. The data set cleaned using Kahn’s framework yielded more accurate results than the data set cleaned without this framework. Future plans involve creating functions in R language for cleaning data extracted from the EHR as well as an R package that combines DQ checks with missing data analysis functions. PMID:27429992

This study explored the mediating factors of sarcopenia in a group of women survivors of breast cancer in Bogotá, Colombia. This was a descriptive cross-sectional study with 98 women survivors of breast cancer, who were registered with the SIMMON (Integrated Synergies to Improve Oncological Management in Colombia) Foundation. Body weight, height, and waist circumference (WC) were measured, and body mass index (BMI) was calculated. Body composition (percentage of fat and muscle mass) was evaluated via four-pole bioelectrical impedance analysis. Sarcopenia was defined as low muscle mass plus low grip strength or low gait speed (European Working Group on Sarcopenia in Older People (EWGSOP) criteria). A "causal" mediation analysis with the Baron & Kenny procedure (PROCESS ® macro, Columbus, OH, USA) was used to explore variables related to sarcopenia. Analyses were performed with the IBM SPSS 21 statistical package (SPSS Inc., Chicago, IL, USA). The significance level of the results obtained in the hypothesis contrast was p < 0.05. The mean age of the sample was 65.5 ± 5.9 years, with a BMI of 27.8 ± 4.7 kg/m². The prevalence of sarcopenia was 22.4%. Linear regression models suggest a partial mediation of anthropometric parameters (body mass, body mass index and waist circumference) in the association between handgrip strength and muscle mass. In conclusion, one in every five women survivors of breast cancer had sarcopenia. The findings seem to emphasize the importance of obesity prevention in women survivors of breast cancer, suggesting that high handgrip strength may not relate closely to greater muscle mass and therefore would not exclude the risk of sarcopenia.

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 aim of this article is to acquaint the general public with select socioeconomic status (SES) parameters (type of work, education level, employment category, and net monthly income) of select nationalities (Ukrainians, Slovaks, Vietnamese, Poles, and Russians) from a total of 1,014 immigrants residing in the Czech Republic. It will also present a subjective assessment of socioeconomic status and its interconnection with subjective assessment of health status. This work was carried out as part of the "Social determinants and their impact on the health of immigrants living in the Czech Republic" project (identification number LD 13044), which was conducted under the auspices of the European Cooperation in Science and Technology (COST) agency. Quantitative methodology in the form of a questionnaire was selected to facilitate the research aim. Data was processed using the Statistical Package for Social Sciences (SPSS), version 16.0 (SPSS, Inc., Chicago, IL, USA). Statistical analyses were performed using the Pearson chi-square test, adjusted residual analysis, and multivariate correspondence analysis. The results of these tests demonstrated a statistically significant relationship between subjective assessments of socioeconomic status and the following related select characteristics: type of work performed (manual/intellectual), employment categories, education, and net monthly income. Results indicate that those situated lowest on the socioeconomic ladder feel the poorest in terms of health; not only from a subjective perspective, but also in terms of objective parameter comparisons (e.g. manual laborers who earn low wages). As the level of subjective SES assessment increases, the level of subjective health assessment increases, as well. Thus, the relationship has a natural gradient, as was described by Wilkinson and Marmot in 2003. Our study found no evidence of a healthy immigrant effect. Therefore, it was not possible to confirm that health status deteriorates with length of residence, or that the health status of immigrants with a residence duration of less than 5 to 10 years is statistically significantly better than immigrants who have resided in the Czech Republic for 10 years or more. We conclude that, by increasing the education levels of immigrants, or actively selecting qualified foreign workers (according to set criteria), the number of people in the Czech Republic who positively assess their health status will surge. In terms of prevention, it is essential to focus on manual laborers and to differentiate specific methods to improve their health status (e.g. awareness-raising campaigns in large plants and factories), given that they comprise the weakest group in this regard.

With economic growth, the use of chemicals has continually increased, resulting in an increase of chemical accidents. Chemical accidents pose a life threat and can lead to many health problems among the residents living in close proximity to chemical plants. This study aimed to investigate the awareness of the residents living near chemical plants about hazardous chemicals, as well as to survey the awareness of workers who do not directly handle chemicals at chemical plants (WNHCs). To this end, a questionnaire survey was conducted among a total of 600 residents and 160 WNHCs. The questionnaire was composed of three items: awareness of chemical risk, awareness of countermeasures in chemical accidents, and imperious necessity of PPE (personal protective equipment). Statistical analysis of the data was performed with the Statistical Package for Social Sciences (SPSS) version 18.0. The results show that the government needs to complement the notification system of chemical risk for residents who live close to chemical plants. The highest priority of PPE which residents want to prepare for chemical accidents was respiratory protective equipment (RPE). They responded that, if necessary to purchase PPE, they could bear a portion of the expenses (up to US $30). This study provides basic data for the development of programs and policies on chemical safety relevant for the residents living in close proximity to chemical plants in South Korea.

Quality of life is an important indicator for evaluating therapeutic outcomes and mortality in patients with end-stage renal disease. Few studies have explored the impact of symptom distress and social support on quality of life in this population. A correlational study was designed to examine the influence of symptom distress, social support and demographic characteristics on quality of life in renal transplant recipients. A convenience sample of 113 renal transplant recipients was recruited from a medical center in Southern Taiwan. A structured questionnaire was used to collect data. This four-part tool included: Quality of Life Index--Kidney Transplant Version III, Physical Symptom Distress Scale, Social Support Scale, and demographic characteristics. Data were analyzed by descriptive and inferential statistics (SPSS 10.1 statistical package). Percentage, rank, mean and standard deviation, t-tests, chi-square, ANOVA, Pearson's correlation and multiple regression were computed. Results showed that renal transplant recipients had a moderate quality of life. Social support and symptom distress, age, employment status, and household income significantly explained 28.8% of the variance in quality of life. Findings suggest implications for interventional programming and research aimed toward improving quality of life, including individual and family-based approaches designed to enhance recipients' social support and address effective management of symptoms. Recruiting a transplant clinical nurse specialist to design and implement an intervention program also is recommended.

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.

Although the issues of singles' dietary style and quality of life are becoming important due to the increasing number of singles with economic power, little research has been conducted to date on singles' use of convenience food and quality of life in relation to their dietary style. Thus, the present study intends to provide basic data to improve the quality of life by determining the current status of the use of convenience food and explicating its relationship with quality of life through analyzing the dietary lifestyles of the singles. The targets of this study were singles, identified as adults between the ages of 25 and 54, living alone, either legally or in actuality having no partner. A statistical analysis of 208 surveys from Seoul, respectively, was conducted using SPSS12.0 for Windows and SEM using AMOS 5.0 statistics package. The convenience-oriented was shown to have a significant positive effect on convenience food satisfaction. HMR satisfaction was found to have a significant effect on positive psychological satisfaction and the convenience-oriented was found to have a significant negative effect on all aspects of quality of life satisfaction. There must be persistent development of food industries considering the distinctive characteristics of the lives of singles in order to satisfy their needs and improve the quality of their lives.

The purpose of this study was to determine the relationship between sweet-liking phenotype and the variation of the gene sequence of the dopaminergic and serotonergic system. The study recruited 100 probands. The participants were interviewed for addiction (SSAGA-Semi Structured Assessment for the Genetics of Alcoholism) and assessed with the questionnaires: MMSE, Beck Depression Inventory and Hamilton Anxiety, Snaith-Hamilton Pleasure Scale. The taste was analyzed with tests to assess sensitivity to sweet taste and also smell tests were performed. Patients preferring the highest glucose volumes were called sweet likers. Statistical analyses were performed (SPSS- Statistical Package for the Social Sciences). Links between sweet liking phenotype and polymorphic variant of DAT1 gene were determined. The presence of DAT1 9/10 genotype increased three fold time sweet liking phenotype (p = 0.015, odds ratio-3.00), the presence of DAT1 10/10 decreased two fold time the chance being sweet liker (p = 0.051, odds ratio-0.43). Genotype 10/10 was significantly more common among sweet dislikers 10/10 (68.18% vs 47.92%) i 9/9 (6.82% vs 2.08%). CONCLUSIONS; A genetically significant association between the presence of 9/10 DAT1 VNTR genotype and a sweet-liking phenotype in probands was determined.

Job satisfaction and work ability are important in the nursing profession to ensure good working conditions and to reduce work-related diseases and illness. Psychosocial factors such as social support and decision latitude (autonomy) could have a role in cardiovascular diseases, low back pain, injuries and sick leave. To evaluate work ability, job satisfaction, psychosocial factors and diseases in 10 departments of the Monfalcone Hospital. The Work Ability Index (WAI) questionnaire and Karasek Job Content Questionnaire with other questions related to working conditions and diseases were administered to 160 nurses working in 10 departments. The response rate was 90%. SPSS Statistic packaging was used for statistical analysis. The study population had a mean age of 41.1 ± 7 years and the majority were female (81.25%). WAI gave a rating of over 37 points (good and excellent) for 86.4%, with an average of 39.9 ± 5.9 in women and 40.6 ± 6.4 in men. The WAI differences between the departments were significant with Medicine and Surgery showing lower values (p=0.012). WAI was significantly lower in subjects with sick leave higher than 10 days per year (p=0.000) and in subjects with cardiovascular diseases (p=0.031). Our study showed very good working conditions for nurses. A follow-up of the analyzed population over time will add further information on this aspect.

Background: Cervical cancer being a major cause of morbidity and mortality in women in developing countries, its awareness is essential. Aim: The aim of this study is to assess the knowledge, attitude and practices of women regarding the basic screening test for detection of cancer cervix. Settings and Design: Population based cross-sectional study. Materials and Methods: Cross-sectional prospective study was conducted. Information from consenting participants (450) was collected using structured questionnaire. Answers were described in terms of knowledge, attitude and practice and their respective adequacy with respect to Papanicolaou (Pap) test, the most common test used for early detection of cervical cancer. Adequacy was compared between the categories of socio demographic and clinical variables. Statistical Analysis: The data collected was analyzed using statistical package (SPSS version 18.0). Adequacy was compared between the categories of the control variables by χ2 test with a 5% significance level. Results: Knowledge, attitude and practices regarding Pap test were adequate in 32.7%, 18.2% and 7.3% of women respectively. Major impediment to adequate practice was lack of request by physician. Knowledge, attitudes and practices were found to increase significantly with increasing age and education. Conclusion: Effective information, education and communication strategies are required to improve the level of awareness of public. Health-care professional should be proactive in imparting knowledge at every opportunity.

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.

To compare the results of two-staged open reduction and internal fixation (ORIF) and limited internal fixation with external fixator (LIFEF) for closed tibial plafond fractures. From January 2005 to June 2007, 56 patients with closed type B3 or C Pilon fractures were randomly allocated into groups I and II. Two-staged ORIF was performed in group I and LIFEF in group II. The outcome measures included bone union, nonunion, malunion, pin-tract infection, wound infection, osteomyelitis, ankle joint function, etc. These postoperative data were analyzed with Statistical Package for Social Sciences (SPSS) 13.0. Incidence of superficial soft tissue infection (involved in wound infection or pin-tract infection) in group I was lower than that in group II (P < 0.05), with significant difference. Group I has significantly less radiation exposure (P < 0.001). Group II had higher rates of malunion, delayed union, and arthritis symptoms, with no statistical significance. Both groups resulted similar ankle joint function. Logistic regression analysis indicated that smoking and fracture pattern were the two factors significantly influencing the final outcomes. In the treatment of closed tibial plafond fractures, both two-staged ORIF and LIFEF offer similar results. Patients undergo LIFEF carry significantly greater radiation exposure and higher superficial soft tissue infection rate (usually occurs on pin tract and does not affect the final outcomes).

Though many women are suffering the consequences of sexual violence, only few victims speak out as it is sensitive and prone to stigma. This lack of data made it difficult to get full picture of the problem and design proper interventions. Thus, the aim of this study was to assess the prevalence and factors associated with sexual violence among female students of Wolaita Sodo University, south Ethiopia. Institution based cross-sectional study was conducted among 462 regular female Wolaita Sodo University students on April 7/2015. Participants were selected by simple random sampling. Data were collected by self-administered questionnaire. Data entry and analysis was done by EPI info and SPSS statistical packages respectively. Descriptive statistics were done. Moreover, bivariate and multivariate analyses were also carried out to identify predictors of sexual violence. The age of respondents ranged from 18 to 26 years. Lifetime sexual violence was found to be 45.4%. However, 36.1% and 24.4% of respondents reported experiencing sexual violence since entering university and in the current academic year respectively. Life time sexual violence was positively associated with witnessing inter-parental violence as a child, rural childhood residence, having regular boyfriend, alcohol consumption and having friends who drink regularly; while it was negatively associated with discussing sexual issues with parents. Sexual violence is a common phenomenon among the students. More detailed research has to be conducted to develop prevention and intervention strategies.

Objective: To describe depression levels in school aged children and adolescents with acute leukemia during the treatment. This transversal descriptive study took place during January to September 2012 and included school aged children and adolescents, carriers of acute leukemia, in treatment at a high-ranking specialty hospital. A modified Kovacs questionnaire (C O/) was applied. They were grouped according to presence or absence of depression. Inferential statistics with x2 and Statistical package SPSS 20.0 were used. Forty-six patients were included in the study: with depression n = 43 (94%), without depression n=3 (6%), males n= 32 (70%) and females n=14 (30%), average age 8 years old (7-15). Acute lymphoblast leukemia was the most frequent n=42 patients (91 %). Depression was found in 42 patients (91 "'o), with nine presenting a minor level (21 "'o), 11 a moderate level (26 "/o), and 23 a severe level (53 "/o). Mostly during the consolidation phase, 30 patients (70"/o) patients with no relapses showed a higher incidence of depression, 23 (54 "/o) vs. with relapses 20 (47"/o) (p = 0.870); the majority had no family history of depression 41 (95 "/o) vs. 2 (5"/o) (p = 0.017). We found a high percentage of severe level depression, which affected mostly male patients, suffering a relapse during the consolidation treatment phase.

Objectives: To determine the health status of periradicular tissue and the quality of root canal fillings in an adult Saudi population attending dental clinics for the first time. Methods: This cross sectional study was conducted in the dental clinics at King Saud University, Riyadh and other dental centers (Jeddah, Najran, and Albaha City), Kingdom of Saudi Arabia between year 2010 and 2012. Good-quality panoramic radiographs of 926 Saudi subjects (540 males and 386 females)were analyzed based on the gender, age, health status, smoking habits, periapical status of the endodontically treated teeth, technical quality of the root canal fillings, and the presence or absence of coronal restoration. Data were calibrated and statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA) version 17. Results: Of the 25,028 teeth examined, 1,556 teeth (6.2%) had apical periodontitis (AP). Male subjects aged over 55 years and females between 36 and 45 years had higher AP. A total of 36 diabetic and 87 smokers subjects had AP. The AP was more common in male diabetics than female (p=0.383), and in female smokers more than male (p=0.44). Only 42.2% of male and 57.7% of female teeth had adequate root canal treatment. Conclusions: Apical periodontitis was significantly related to diabetes, smoking, and inadequate endodontic treatment.

Obesity has become a major health problem in contemporary society and it is closely related to many chronic diseases, so it is an important issue for measuring adiposity accurately and predicting its future. Prevention and treatment of overweight and obesity has become one of the key prevention and treatment of metabolic disorders. In this study, we compared the ability of the four anthropometric indicators (body mass index, waist circumstance, waist-height ratio, waist-to-hip ratio) to identify metabolic disorders (hypertension, hyperlipidaemia, hyperglycemia and hyperuricemia) by receiver operating characteristic (ROC) curve analyses and to provide evidence for clinical practice. In this large scale cross-sectional study, 13,275 Han adults (including 7595 males and 5680 females) received physical examination between January, 2009 and January, 2010 in Xuanwu Hospital of Capital Medical University were investigated by the means of questionnaire, Meanwhile, the physical examination and serological results were recorded. A package known as Statistical Package for Social Scientist (SPSS) was employed to analyse the responses while t-test, one-way analysis of variance (ANOVA), ROC analysis and chi-square statistical methods were used to test the hypotheses. WC, WHtR, WHR and BMI were all significantly (P < 0.001) correlated with all metabolic risk factors regardless of gender. And the area under the curve (AUC) of WHtR was significantly greater than that of WC, BMI or WHR in the prediction of hypertension, hyperlipidaemia, hyperglycemia and hyperuricemia. Our data show that WHtR was the best predictor of various metabolic disorders. The diagnostic value in descending order was WHtR > WHR > WC > BMI. Therefore we recommend WHtR in assessment of obese patients, in order to better assess the risks of their metabolic diseases. Copyright © 2015 The Royal Society for Public Health.

Khatri, Ayisha Al; Jens, Grundmann; der Weth Rüdiger, van; Niels, Schütze

2015-04-01

Al Batinah coastal area is the main agricultural region in Oman. Agriculture is concentrated in Al Batinah, because of more fertile soils and easier access to water in the form of groundwater compared to other administrative areas in the country. The region now is facing a problem as a result of over abstraction of fresh groundwater for irrigation from the main aquifer along the coast. This enforces the inflow of sea water into the coastal aquifer and causes salinization of the groundwater. As a consequence the groundwater becomes no longer suitable for irrigation which impacts the social and economical situation of farmers as well as the environment. Therefore, the existing situation generates conflicts between different stakeholders regarding water availability, sustainable aquifer management, and profitable agricultural production in Al Batinah region. Several management measures to maintain the groundwater aquifer in the region, were implemented by the government. However, these solutions showed only limited successes for the existing problem. The aim of this study now is to evaluate the implementation potential of several management interventions and their combinations by analysing opinions and responses of all relevant stakeholders in the region. This is done in order to identify potential conflicts among stakeholders to a participatory process within the frame of an integrated water resources management and to support decision makers in taking more informed decisions. Questionnaires were designed for collecting data from different groups of stakeholders e.g. water professionals, farmers from the study area and decision makers of different organizations and ministries. These data were analysed statistically for each group separately as well as regarding relations amongst groups by using the SPSS (Statistical Package for Social Science) software package. Results show, that the need to improve the situation is supported by all groups. However, significant differences exist between groups on how to achieve this improvement, since farmers prefer management interventions operating more on the water resources side while decision makers support measures for a better management on the water demand side. Furthermore, the opinions within single groups are sometimes contradicting for several management interventions. The use of more advanced statistical methods like discriminant analysis or Bayesian network allow for identifying factors and drivers to explain these differences. Both approaches, will help to understand stakeholder's behaviours and to evaluate the implementation potential of several management interventions.

Vestibular Evoked Myogenic Potentials (VEMP) is an emerging tool to diagnose Benign Paroxysmal Positional Vertigo (BPPV). The clinical utility of VEMP has been reported only in small accord in Indian literature. To study the latency and amplitude of VEMP in patients with BPPV and compare it with that of normal subjects. The study included two groups. Group one (control group) were 18 normal subjects. Group two (test group) were 15 subjects with unilateral BPPV. Those subjects who fulfilled the selection criteria based on case history and audiological assessment were taken for the VEMP recording. The VEMP response consist of positive and negative successive waves (pI-nI), with latency values in adults about 13 and 23 milliseconds respectively. Data was analysed using Statistical Package for Social Sciences (SPSS) version 12 (Chicago, IL, USA). Unpaired t-test was employed to measure the statistical difference between control group and test group. The difference in n23 and the peak to peak amplitude between the ipsilateral and contralateral ears of the test group were statistically significant, whereas such a difference in the p13 latency turned out to be statistically insignificant. It should be noted that, out of 15 patients in the test group, five patients showed only artifact tracer recordings in both the ears which is considered as no response. The heterogeneity of the results extended from absence of VEMP to prolongation of both p13, n23; prolongation of p13 alone; and even side to side variations. Absent response from the ipsilateral ear, prolonged latency of n23 and decreased peak to peak amplitude (p13, n23), indicates the disease pathology. However, large sample size is required to draw further conclusions and to consolidate the usage of VEMP in the diagnosis of BPPV.

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.

2014-01-01

Background Although there are accumulating data regarding the epidemiology of suicide in China, there are meager data on suicidal ideation and attempts among college students. Interestingly, elevated impulsivity is thought to facilitate the transition from suicidal thoughts to suicidal behavior. Therefore, the objective of this research was to identify the associations between suicide and the personality factors of impulsivity and aggression. Methods This study’s sampling method employed stratified random cluster sampling. A multi-stage stratified sampling procedure was used to select participants (n = 5,245). We conducted structured interviews regarding a range of socio-demographic characteristics and suicidal morbidity. The Patient Health Questionnaire depression module (PHQ-9) was used to acquire the information about thoughts of being better off dead or hurting themselves in some ways during the past two weeks. The impulsivity symptoms in this study were assessed with the BIS-11-CH (i.e., the Chinese version of the BIS-11), and the Aggressive symptoms were assessed with the BAQ. The statistical package for social science (SPSS) v.13.0 program (SPSS Inc., Chicago, IL, USA) was used for statistical analysis. Socio-demographic variables such as ethnic and gender were compared between groups, through the use of χ2 tests. The nonparametric test (k Independent Sample test, Kruskal-Wallis H) was performed to determine differences between the personality factors of impulsivity and aggression and suicide. Results In total, 9.1% (n = 479) of the 5,245 students reported they have ever thought about committing suicide; and 1% (n = 51) reported a history of attempted suicide (attempters). The analyses detected significant differences in scores on cognitive impulsivity (p < 0.01), when comparing individuals who only had suicidal ideation and individuals who had attempted suicide. Moreover, significant differences were found between ideators only and attempters on scores of self-oriented attack (p < .001). Conclusions Suicidal ideation is prevalent among Chinese university students. Students with high aggression scores were more susceptible to committing suicide. Scores on self-oriented attack and cognitive impulsivity may be important factors for differentially predicting suicide ideation and suicide attempts. PMID:24894449

The most important determinant of suicide ideation, tendency and initiative is the presence of mental disorders. Since the number of those who lost their lives due to suicide in the world rose rapidly among the young population, the World Health Organization emphasizes the importance of assessing young people in the high-risk age group to prevent suicidal behavior. This study aimed to determine psychological symptom levels and suicide probability in young people. The cross-sectional research consisted of 15-24 year-old individuals (N=348), who have sought a psychiatric clinic between February and June, 2015. The Research Data was collected by applying Data Collection Form, Suicide Probability Scale (SPS) and Brief Symptom Inventory (BSI). SPSS 22.0 statistical package program was used for data analysis. There was a statistically significant difference (p<0.05) between the mean SPS scores according to education, psychiatric treatment, self-harm, smoking and drinking status of the participants in the study. Apart from this, there was also a statistically significant correlation between anxiety, depression, negative self and hostility according to the SPS and BSI subscales (p<0.001, r=0.739; p<0.001, r=0.729; p<0.001, r=0.747; p<0.001, r=0.715; respectively). The results of our study show that suicide risk is significantly higher in young people with depression, anxiety, negative self-perception and hostility symptoms. In this regard, we suggest the relevance of assessing the suicide risk of young people seeking a psychiatric clinic, with thorough attention to those who have high potential for suicide.

Ovarian cancer is recognized as the fourth leading cancer in Malaysia. However, women do not always seek help in a timely manner and gaps in awareness may influence screening uptake and presentation. The purpose of this study was to determine levels of awareness of ovarian cancer risk factors in female population in Penang, Malaysia. A cross-sectional study was conducted in Penang, Malaysia from January until February 2014. Eighty-seven women were selected by convenient sampling. Awareness of risk factors of ovarian cancer was assessed using a self-administered questionnaire. Data were analyzed using statistical package for the social sciences (SPSS) version 20.0 for descriptive statistics and Pearson chi-square test for the association between socio-demographic data and awareness. A p value ≤0.05 was considered statistically significant. In all, 74.7% of participants answered correctly for the risk factor of increasing age, although 94.3% were unaware of increased risk of tall women. A majority, 71.3%, had a low level of awareness of ovarian cancer risk factors. There was a significant association between age and knowledge (p=0.047). Additionally, there was a significant association between higher education level and level of awareness of ovarian cancer risk factors (p=0.039). This study revealed that awareness of ovarian cancer risk factors among Malaysian women is low. The results show a need for improved public understanding about ovarian cancer risks and provision of important information for health professionals about initiatives needed for future awareness, prevention and screening programs.

Objective We aimed to investigate the attitudes and behaviors of anaesthesiologists in “non-operating room anaesthesia” applications, which can be described as anaesthesia applications performed outside the operating room, and their reflection on practice all over Turkey. Methods Our study was conducted between November 5, 2012 and January 7, 2013 with the approval of the Research Ethics Board. Survey data were obtained through distributing printed questionnaires to be completed either by hand or via the web. The questionnaire consisted of 38 questions. The data obtained were analyzed with the Statistical Package for Social Sciences (SPSS) program. Results A total of 500 anaesthesiologists replied to our survey; 93% of anaesthesia specialists reported that there was a request that the anaesthesia and anaesthesia outside the operating room was given in their institution. Among anaesthesiologists, 56% reported that there were other sections that can provide sedation other than the anaesthesiology department in their institutions. Anaesthesia care team members; equipment; anaesthetic techniques; monitoring methods; and hypnotic, analgesic, and antagonist agents had statistically significant differences according to the participants’ institutions. Equipment used in the anaesthesia practice outside the operating room, anaesthesia, and monitoring methods had statistically significant differences according to geographical distribution (p<0.05). Conclusion Outside the operating room, anaesthesia practices and security measures are compliant with the standards set by the guidelines, the key to the prevention of complications. In our study, the current status of anaesthetic procedures outside the operating room in our country have been analyzed. PMID:27366420

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.

Length of long bones is taken as an important contributor for estimating one of the four elements of forensic anthropology i.e., stature of the individual. Since physical characteristics of the individual differ among different groups of population, population specific studies are needed for estimating the total length of femur from its segment measurements. Since femur is not always recovered intact in forensic cases, it was the aim of this study to derive regression equations from measurements of proximal and distal fragments in Nepalese population. A cross-sectional study was done among 60 dry femora (30 from each side) without sex determination in anthropometry laboratory. Along with maximum femoral length, four proximal and four distal segmental measurements were measured following the standard method with the help of osteometric board, measuring tape and digital Vernier's caliper. Bones with gross defects were excluded from the study. Measured values were recorded separately for right and left side. Statistical Package for Social Science (SPSS version 11.5) was used for statistical analysis. The value of segmental measurements were different between right and left side but statistical difference was not significant except for depth of medial condyle (p=0.02). All the measurements were positively correlated and found to have linear relationship with the femoral length. With the help of regression equation, femoral length can be calculated from the segmental measurements; and then femoral length can be used to calculate the stature of the individual. The data collected may contribute in the analysis of forensic bone remains in study population.

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.

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.

In 2007, the European Association of Palliative Care (EAPC) provided a comprehensive set of recommendations and standards for the provision of adequate pediatric palliative care. A number of studies have shown deficits in pediatric palliative care compared to EAPC standards. In Germany, pediatric palliative care patients can be referred to specialized outpatient palliative care (SOPC) services, which are known to enhance quality of life, e.g. by avoiding hospitalization. However, current regulations for the provision of SOPC in Germany do not account for the different circumstances and needs of children and their families compared to adult palliative care patients. The "Evaluation of specialized outpatient palliative care (SOPC) in the German state of Hesse (ELSAH)" study aims to perform a needs assessment for pediatric patients (children, adolescents and young adults) receiving SOPC. This paper presents the study protocol for this assessment (work package II). The study uses a sequential mixed-methods study design with a focus on qualitative research. Data collection from professional and family caregivers and, as far as possible, pediatric patients, will involve both a written questionnaire based on European recommendations for pediatric palliative care, and semi-structured interviews. Additionally, professional caregivers will take part in focus group discussions and participatory observations. Interviews and focus groups will be tape- or video-recorded, transcribed verbatim and analyzed in accordance with the principles of grounded theory (interviews) and content analysis (focus groups). A structured field note template will be used to record notes taken during the participatory observations. Statistical Package for Social Sciences (SPSS, version 22 or higher) will be used for descriptive statistical analyses. The qualitative data analyses will be software-assisted by MAXQDA (version 12 or higher). This study will provide important information on what matters most to family caregivers and pediatric patients receiving SOPC. The results will add valuable knowledge to the criteria that distinguish SOPC for pediatric from SOPC for adult patients, and will provide an indication of how the German SOPC rule of procedure can be optimized to satisfy the special needs of pediatric patients.

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. 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. 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. CBCT-derived images were less reliable as compared to data obtained directly from plaster model for mixed dentition analysis.

Power laws are theoretically interesting probability distributions that are also frequently used to describe empirical data. In recent years, effective statistical methods for fitting power laws have been developed, but appropriate use of these techniques requires significant programming and statistical insight. In order to greatly decrease the barriers to using good statistical methods for fitting power law distributions, we developed the powerlaw Python package. This software package provides easy commands for basic fitting and statistical analysis of distributions. Notably, it also seeks to support a variety of user needs by being exhaustive in the options available to the user. The source code is publicly available and easily extensible.

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.

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.

Industrialized Building System (IBS) is one of the approaches that had been introduced as an alternative to conventional building method where it becomes the new strategy of enhancing the sustainable construction in current industries while spearheading a huge advancement of benefits with green constructions into the existing industries. The IBS approach is actively promoted through several strategies and incentives as an alternative to conventional building methods. Extensive uptakes of modern Information Communication Technology (ICT) applications are able to support the different IBS processes for effective production. However, it is argued that ICT uptake at the organisational level is still in its infancy. This raises the importance to identify critical inhibitors which are inhibing the effective uptake of ICT in the IBS production management process. Critical inhibitors to ICT uptake were identified through questionnaire survey with the IBS industry stakeholders. The mean index and critical t-values are generated with the use of the quantitative tool, Statistical Package for Social Sciences (SPSS). The top ten priority ranked inhibitors reflect the Cost, People and Process elements to ICT uptake. High costs in acquiring the technologies and resistance to change were some main concerns from the findings.

Psychological well-being as one of the most important indicators of successful aging has received substantial attention in the gerontological literature. Prior studies show that sociodemographic factors influencing elderly's psychological well-being are multiple and differ across cultures. The aim of this study was to identify significant sociodemographic predictors of psychological well-being among Malay elders. The study included 1415 older Malays (60-100 years, 722 women), randomly selected through a multistage stratified random method from Peninsular Malaysia. WHO-Five well-being index was used to measure psychological well-being. Data analysis was conducted using the Statistical Package for Social Sciences (SPSS) version 13.0. Using multiple regression analysis a significant model emerged (F(7, 1407) = 20.14, p ≤ 0.001), where age, sex, marital status, and household income were significant predictor variables of psychological well-being among Malay elders. However, level of education, employment status, and place of residence failed to predict psychological well-being. This study showed that the oldest old, elderly women, unmarried, and the poor elderly people are at risk for experiencing low psychological well-being. Therefore, they need special attention from family, policy makers, and those who work with elderly people.

Regarding the problems in the reform of the railway tariff system and the pricing of the transport, by means of assaying the influence of the price elasticity on the artifice used for price, this article proposed multiple regressive model which analyzed price elasticity quantitatively. This model conclude multi-factors which influences on the price elasticity, such as the averagely railway freight charge, the averagely freight haulage of proximate supersede transportation mode, the GDP per capita in the point of origin, and a series of dummy variable which can reflect the features of some productive and consume demesne. It can calculate the price elasticity of different classes in different domains, and predict the freight traffic volume on different rate levels. It can calculate confidence-level, and evaluate the relevance of each parameter to get rid of irrelevant or little relevant variables. It supplied a good theoretical basis for directing the pricing of transport enterprises in market economic conditions, which is suitable for railway freight, passenger traffic and other transportation manner as well. SPSS (Statistical Package for the Social Science) software was used to calculate and analysis the example. This article realized the calculation by HYFX system(Ministry of Railways fund).

Lewis, Heather Smith; Cunningham, Christopher J L

2016-01-01

Burnout and engagement are critical conditions affecting patient safety and the functioning of healthcare organizations; the areas of worklife model suggest that work environment characteristics may impact employee burnout and general worklife quality. The purpose was to present and test a conditional process model linking perceived transformational nurse leadership to nurse staff burnout and engagement via important work environment characteristics. Working nurses (N = 120) provided perceptions of the core study variables via Internet- or paper-based survey. The hypothesized model was tested using the PROCESS analysis tool, which enables simultaneous testing of multiple, parallel, indirect effects within the SPSS statistical package. Findings support the areas of worklife model and suggest that transformational leadership is strongly associated with work environment characteristics that are further linked to nurse burnout and engagement. Interestingly, different work characteristics appear to be critical channels through which transformational leadership impacts nurse burnout and engagement. There are several methodological and practical implications of this work for researchers and practitioners interested in preventing burnout and promoting occupational health within healthcare organizations. These implications are tied to the connections observed between transformational leadership, specific work environment characteristics, and burnout and engagement outcomes.

Various researchers examined chemical composition and nutritional values of edible parts of dates while limited information about chemical composition and nutritional quality of date seed is available. In this study, fatty acid composition and total tocopherol content of 14 Iranian date seed oils were studied. Statistical analysis was performed through SPSS computing package. According to the fatty acid profiles, seven fatty acids were found through nearly 50% oleic acid in seeds. Shekar cultivar by 51.40% had the maximum amount and Lasht cultivar by 33.38% had the minimum amount of oleic acid. Tocopherol content in the samples varied between 33.86 μg vit E/g oil for Shahabi2 to 10.09 μg vit E/g oil for Shekar. Tocopherol content was 1.88 and 0.61 μg respectively in one-gram seed of these two cultivars. Iranian date seed oils classified as oleic-lauric oil, had a high amount of oleic acid and could serve as a profitable source of valuable oils for industrial applications.

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.

Objectives: This study attempts to highlight the usefulness of applying Berry's Index as an adjuvant to support and aid in bite analysis. Materials and Methods: This study was conducted among 100 students between the ages of 18–30 from Mar Baselios Dental Collage, Kothamangalam. Out of the 100 subjects, there were 50 males and 50 females. The data obtained was tabulated and analyzed using Statistical Package for Social Sciences, Version 16 (SPSS). Results: The mean value of the width of the upper central incisor for male and female was 0.7602 cm and 0.7765 cm respectively. The mean value of the bizygomatic width for male and female was 12.54 cm and 12.42 cm respectively. The correlation between the upper central incisor width and the bizygomatic width was inferred to have a good positive correlation with a value 0f 0.613. Pearson correlation coefficient with greater correlation between the upper central incisor width and the bizygomatic width in female patient (r = 0.678) compared with male patient (r = 0. 525). Conclusion: Berry's Index can be a useful adjuvant to bite analysis by providing a means of determining the facial proportions of an individual from the width of the central incisors. PMID:25709316

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.

To investigate the impact of age factor on root resorption and the prevalence in anterior teeth during orthodontic treatment. Sixty extraction cases treated with straight wire appliance were divided into adult group and child group, with 30 cases in each group.The panoramic radiographs pre-treatment and post-treatment were examined to measure the degrees of root resorption. A total of 360 anterior teeth in each group were evaluated. SPSS 13.0 software package was applied to perform statistical analysis. There was significant difference in root resorption index before and after treatment(P<0.01). The incidence of root resorption increased remarkably after orthodontic treatment. There was significant difference in the degree of root resorption in two groups (P<0.01). The prevalence of root resorption in anterior teeth was: upper central incisors, upper lateral incisors, lower central incisors, lower lateral incisors, upper canines and lower canines. The root resorption in adult patients are more obvious than child patients. The prevalence of root resorption in anterior teeth is different. Moderate or severe root resorption is prone to happen in upper central incisors or lateral incisors in adult patients.

Hypokalemia is not an isolated disease but an associated finding in a number of different diseases. It is also a commonly neglected condition among patients with acute acetaminophen overdose. This study intended to determine the prevalence of hypokalemia and its clinical correlates in acute psychiatric illness among hypokalemic and normokalemic patients after acetaminophen overdose. This is a retrospective cohort study of hospital admissions for acute acetaminophen overdose conducted over a period of 5 years from 1 January 2004 to 31 December 2008. Demographic data and different types of psychiatric illness were compared between hypokalemic and normokalemic patients. Hypokalemia was predefined by a serum concentration <3.5 mmol/L. Statistical Package for Social Sciences (SPSS) 15 was used for data analysis. Two hundred and eighty patients out of 305 admissions were studied. Hypokalemia was found in 63.6% of patients with a higher prevalence in the presence of psychiatric illness (67.7%). Hypokalemic patients were significantly associated with the presence of major depression (p = .04), adjustment disorder (p < .001), anxiety (p = .01), and suicidal attempts (p = .04). Hypokalemia was common among patients with psychiatric illness and acute acetaminophen overdose.

To assess intelligence and its relationship with blood phenylalanine concentrations and socioeconomic status in patients with phenylketonuria after 6 to 12 years of treatment. Sixty-three children were classified according to phenylalanine levels and socioeconomic status and assessed using the Wechsler Intelligence Scale for Children. The Statistical Package for the Social Sciences (SPSS) was used to analyze phenylalanine; ANOVA was used to analyze intelligence quotients (IQ) and phenylalanine levels; and ordinal logistic regression was used to analyze the likelihood of higher IQ. The overall IQ scores of 90.5% of the children were within a range from borderline intellectual deficiency to very high intelligence; for verbal IQ this proportion was 96.8% and 92.1% had performance IQ scores within this band. The categories from low to upper-medium socioeconomic status contained 98.4% of patients' families. The likelihood of having medium to high IQ was 4.29 times greater for children with good phenylalanine control and 4.03 greater for those from higher socioeconomic strata. Treatment prevented mental retardation in 90.5% of the patients. Control of phenylalanine levels and higher socioeconomic status were associated with higher IQ scores.

It is important that every member of our community should be trained in effective BLS technique to save lives. At least doctors including dental practitioners, and medical and paramedical staff should be trained in high quality CPR, as it is a basic medical skill which can save many lives if implemented timely. Our aim was to study the awareness of Basic Life Support (BLS) among dental students and practitioners in New Delhi. This cross sectional study was conducted by assessing responses to 20 selected questions pertaining to BLS among dental students, resident doctors/tutors, faculty members and private practitioners in New Delhi. All participants were given a printed questionnaire where they had to mention their qualifications and clinical experience, apart from answering 20 questions. Data was collected and evaluated using commercially available statistical package for social sciences (SPSS version 12). One hundred and four responders were included. Sadly, none of our responders had complete knowledge about BLS. The maximum mean score (9.19 ± 1.23) was obtained by dentists with clinical experience between 1-5 years. To ensure better and safer healthcare, it is essential for all dental practitioners to be well versed with BLS.

Logistic Regression with Multiple Random Effects: A Simulation Study of Estimation Methods and Statistical Packages.

PubMed

Kim, Yoonsang; Choi, Young-Ku; Emery, Sherry

2013-08-01

Several statistical packages are capable of estimating generalized linear mixed models and these packages provide one or more of three estimation methods: penalized quasi-likelihood, Laplace, and Gauss-Hermite. Many studies have investigated these methods' performance for the mixed-effects logistic regression model. However, the authors focused on models with one or two random effects and assumed a simple covariance structure between them, which may not be realistic. When there are multiple correlated random effects in a model, the computation becomes intensive, and often an algorithm fails to converge. Moreover, in our analysis of smoking status and exposure to anti-tobacco advertisements, we have observed that when a model included multiple random effects, parameter estimates varied considerably from one statistical package to another even when using the same estimation method. This article presents a comprehensive review of the advantages and disadvantages of each estimation method. In addition, we compare the performances of the three methods across statistical packages via simulation, which involves two- and three-level logistic regression models with at least three correlated random effects. We apply our findings to a real dataset. Our results suggest that two packages-SAS GLIMMIX Laplace and SuperMix Gaussian quadrature-perform well in terms of accuracy, precision, convergence rates, and computing speed. We also discuss the strengths and weaknesses of the two packages in regard to sample sizes.

Network meta-analysis (NMA) – a statistical technique that allows comparison of multiple treatments in the same meta-analysis simultaneously – has become increasingly popular in the medical literature in recent years. The statistical methodology underpinning this technique and software tools for implementing the methods are evolving. Both commercial and freely available statistical software packages have been developed to facilitate the statistical computations using NMA with varying degrees of functionality and ease of use. This paper aims to introduce the reader to three R packages, namely, gemtc, pcnetmeta, and netmeta, which are freely available software tools implemented in R. Each automates the process of performing NMA so that users can perform the analysis with minimal computational effort. We present, compare and contrast the availability and functionality of different important features of NMA in these three packages so that clinical investigators and researchers can determine which R packages to implement depending on their analysis needs. Four summary tables detailing (i) data input and network plotting, (ii) modeling options, (iii) assumption checking and diagnostic testing, and (iv) inference and reporting tools, are provided, along with an analysis of a previously published dataset to illustrate the outputs available from each package. We demonstrate that each of the three packages provides a useful set of tools, and combined provide users with nearly all functionality that might be desired when conducting a NMA. PMID:25541687

The Rank Product (RP) is a statistical technique widely used to detect differentially expressed features in molecular profiling experiments such as transcriptomics, metabolomics and proteomics studies. An implementation of the RP and the closely related Rank Sum (RS) statistics has been available in the RankProd Bioconductor package for several years. However, several recent advances in the understanding of the statistical foundations of the method have made a complete refactoring of the existing package desirable. We implemented a completely refactored version of the RankProd package, which provides a more principled implementation of the statistics for unpaired datasets. Moreover, the permutation-based P -value estimation methods have been replaced by exact methods, providing faster and more accurate results. RankProd 2.0 is available at Bioconductor ( https://www.bioconductor.org/packages/devel/bioc/html/RankProd.html ) and as part of the mzMatch pipeline ( http://www.mzmatch.sourceforge.net ). rainer.breitling@manchester.ac.uk.

Our study finds out drug usage trends in over weight and obese patients without any compelling indications in Karachi, looks for deviations of current practices from evidence based antihypertensive therapeutic guidelines and identifies not only cost minimization opportunities but also communication strategies to improve patients' awareness and compliance to achieve therapeutic goal. In present study two sets were used. Randomized stratified independent surveys were conducted in hospital doctors and family physicians (general practitioners), using pretested questionnaires. Sample size was 100. Statistical analysis was conducted on Statistical Package for Social Science (SPSS). Opportunities of cost minimization were also analyzed. One the basis of doctors' feedback, preference is given to non-pharmacologic management of obesity. Mass media campaign and media usage were recommended to increase patients awareness and patients' education along with strengthening family support systems was recommended for better compliance of the patients to doctor's advice. Local therapeutic guidelines for weight reduction were not found. Feedbacks showed that global therapeutic guidelines were followed by the doctors practicing in the community and hospitals in Karachi. However, high price branded drugs were used instead of low priced generic therapeutic equivalents. Patient's education is required for better awareness and improving patients' compliance. The doctors found preferring brand leaders instead of low cost options. This trend increases cost of therapy by 0.59 to 4.17 times. Therefore, there are great opportunities for cost minimization by using evidence-based clinically effective and safe medicines.

Systemic inflammation, therapy with corticosteroids, and reduced physical activity may increase the predisposition to accumulate body fat in patients with systemic lupus erythematosus (SLE). The aim of this study was to assess the nutritional status and food intake of patients with SLE. One hundred seventy women with SLE were evaluated consecutively in a cross-sectional study. Nutritional status was assessed by subjective global assessment and body mass index. Food intake was assessed by a 24-h recall and a semiquantitative food frequency questionnaire. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS), considering P < 0.05 as significant. The mean ± SD age of the patients was 39.14 ± 9.98 y, and the duration of the disease was 9.94 ± 6.18 y. Approximately 91.8% patients were classified as being well nourished; 6.5% were classified as suspected or moderately malnourished, and 1.8% were classified as severely malnourished. In terms of body mass index, malnutrition was found in 1.2% of the patients, normal weight in 35.9%, overweight in 35.3%, and obesity in 27.7%. Most patients reported food consumption below the estimated needs for energy. Calcium was the nutrient with the most inadequate intake. Low consumption of fruits, vegetables, and dairy products and a high consumption of oils and fats were reported. The results showed that patients with SLE have inadequate nutritional status and food intake. Copyright © 2012 Elsevier Inc. All rights reserved.

Assessing cultural validity in standardized tests in stem education

NASA Astrophysics Data System (ADS)

Gassant, Lunes

This quantitative ex post facto study examined how race and gender, as elements of culture, influence the development of common misconceptions among STEM students. Primary data came from a standardized test: the Digital Logic Concept Inventory (DLCI) developed by Drs. Geoffrey L. Herman, Michael C. Louis, and Craig Zilles from the University of Illinois at Urbana-Champaign. The sample consisted of a cohort of 82 STEM students recruited from three universities in Northern Louisiana. Microsoft Excel and the Statistical Package for the Social Sciences (SPSS) were used for data computation. Two key concepts, several sub concepts, and 19 misconceptions were tested through 11 items in the DLCI. Statistical analyses based on both the Classical Test Theory (Spearman, 1904) and the Item Response Theory (Lord, 1952) yielded similar results: some misconceptions in the DLCI can reliably be predicted by the Race or the Gender of the test taker. The research is significant because it has shown that some misconceptions in a STEM discipline attracted students with similar ethnic backgrounds differently; thus, leading to the existence of some cultural bias in the standardized test. Therefore the study encourages further research in cultural validity in standardized tests. With culturally valid tests, it will be possible to increase the effectiveness of targeted teaching and learning strategies for STEM students from diverse ethnic backgrounds. To some extent, this dissertation has contributed to understanding, better, the gap between high enrollment rates and low graduation rates among African American students and also among other minority students in STEM disciplines.

Given that happiness is an important construct to enable adolescents to cope better with difficulties and stress of life, it is necessary to advance our knowledge about the possible etiology of happiness in adolescents. The present study sought to investigate the relationships of emotional intelligence, depressive symptoms, and happiness in a sample of male students in Tehran, Iran. This cross-sectional study was conducted on a sample of high school students in Tehran in 2012. The participants comprised of 188 male students (aged 16 to 19 years old) selected by multi-stage cluster sampling method. For gathering the data, the students filled out assessing emotions scale, Beck depression inventory-II, and Oxford happiness inventory. Data analysis was carried out using descriptive and analytical statistics in statistical package for social sciences (SPSS) software. The findings showed that a significant positive association existed between high ability of emotional intelligence and happiness (P < 0.01). Conversely, the low ability of emotional intelligence was associated with unhappiness (P < 0.01), there was a positive association between non-depression symptoms and happiness (P < 0.05), and severe depressive symptoms were positively associated with unhappiness (P < 0.01). High ability of emotional intelligence (P < 0.01) and non-depression symptoms (P < 0.05) were the strongest predictors of happiness. These findings reinforced the importance of emotional intelligence as a facilitating factor for happiness in adolescences. In addition, the findings suggested that depression symptoms may be harmful for happiness in adolescents.

to evaluate the correlations between perceived state anxiety during chemotherapy and quality of life in metastatic breast cancer patients. 62 metastatic breast cancer patients were evaluated during chemotherapy concerning age, living environment, marital status, social support and preexisting financial difficulties, the histological type of cancer, the site of the metastasis, the time from diagnosis, the type of surgical intervention, dexamethasone use, somatic comorbidities and the radiotherapy. The STAI-X1, BDI- IIA and the QLQ 30 (Quality of Life Questionnaire 30) plus BR 23 (Breast 23) questionnaires were applied. For the statistical analysis we used the SPSS 13 package. 24 subjects were experiencing low state anxiety (< or =39), whilst 38 had significant state anxiety (>39). Statistically significant differences were encountered between the two compared subgroups concerning the living environment, the type of surgical intervention, the marital status, the social support and the mean BDI scores, adjusted means were calculated for the items considered to potentially influence quality of life. Social, emotional and role functioning had lower scores in the low state anxiety group. Fatigue, future perspective, chemotherapy induced side effects, breast symptoms, upset by hair loss and sexual functioning were more disturbing in the high state anxiety group. The general health/quality of life mean score was lower in the low state anxiety group. Higher state anxiety correlates with certain quality of life items, suggesting that psychological counselling and appropriate therapy induced side effects management should be a priority in the palliative care for metastatic breast cancer patients.

To find cytology changes among women attending obstetrics and gynaecology clinic with complaints of vaginal discharges. This descriptive hospital-based cytological study was conducted at the outpatient clinic of the obstetrics and gynaecology department. Two hundred women with complaints of vaginal discharge were selected. Their detailed histories were documented on a special request form. Pap smears were then obtained and sent for cytological examination to the cytopathology department. All low-grade squamous intraepithelial lesion (LSIL) cases were advised to follow-up with Pap smears in the next 6-12 months. Those with high-grade squamous intraepithelial lesion (HSIL) were further investigated by a cervical biopsy and managed accordingly. The statistical analysis was performed using, the Statistical Package for Social Science (SPSS). Chi-square and cross-tabulation were used in this study. The cytological examination of Pap smears showed no changes (i.e. negative findings) in 88 (44%) cases, while Candida species infection was the most prevalent, which was found in 67 (33.5%) of the cases. Bacterial vaginosis was found in 39 women (19.5%); 6 women (3%) were reported with dyskaryotic changes. Two cases were found to have LSIL and 4 women had HSIL. Infection is common among the illiterate group of women. Women with vaginal discharges should undergo screening tests for evaluation by cervical smear for the early detection of cervical precancer conditions. There is an urgent need to establish a screening program for cervical cancer in Sudan.

Risk sexual practice among students from public universities/colleges is common in Ethiopia. However, little has been known about risk sexual behavior of students in private colleges where more students are potentially enrolled. Therefore, this study aimed to assess the magnitude of risky sexual behaviors and predictors among students of Private Colleges in Mekelle City. A mixed design of both quantitative and qualitative methods was used among 627 randomly selected students of private colleges from February to march 2013. Self administered questionnaire and focus group discussion was used to collect data. A thematic content analysis was used for the qualitative part. For the quantitative study, Univariate, Bivariate and multivariable analysis was made using SPSS version 16 statistical package and p value less than 0.05 was used as cut off point for a statistical significance. Among the total 590 respondents, 151 (29.1%) have ever had sex. Among the sexually active students, 30.5% reported having had multiple sexual partners and consistent condom use was nearly 39%. In multivariable logistic regression analysis, variables such as sex, age group, sex last twelve months and condom use last twelve months was found significantly associated with risky sexual behavior. The findings of qualitative and quantitative study showed consistency in presence of risk factors. Finding of this study showed sexual risk behaviors is high among private colleges such as multiple sexual partners and substance use. So that colleges should emphasis on promoting healthy sexual and reproductive health programs.

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

With the growth of forensic odontology, dental records have become an essential source of information, especially for medicolegal cases in general practice. It is mandated by the law that every dentist must keep some kind of records for every patient they treat. After the death of an individual, remnants of teeth are usually damaged at the last among all body parts. Dental records assist in personal identification in cases of mass disasters, criminal investigations, and medicolegal issues. However, in India, rules for maintaining dental records are not very strictly followed. Thus, the aim of this study was to evaluate the knowledge regarding the maintenance of dental records among dentists in Punjab and Uttar Pradesh. Data collection was performed via a questionnaire. The study population responded to the questions pertaining to knowledge regarding forensic odontology methods and the mode of maintaining dental records in their regular practice through a personal interview. A descriptive analysis was carried out for the data. The data were summarized and analyzed using the statistical software Statistical Package for the Social Sciences (SPSS) version 18.0. A very low percentage (22%) of the dentists were seen to be maintaining records on a regular basis. Seventy-eight percent of the dentists were not maintaining any records. This study clearly indicates that the dentists in Punjab and Uttar Pradesh need to be properly trained for any kind of forensic and medicolegal needs.

To investigate the effect of fluoride on electrochemical corrosion of the dental pure titanium before and after adhesion of Streptococcus mutans. The dental pure titanium specimens were tested by electrochemical measurement system including electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization curve (PD) methods in artificial saliva with 0 g/L and 1.0 g/L sodium fluoride before and after dipped into culture medium with Streptococcus mutans for 24 h. The corrosion parameters, including the polarization resistance (R(ct)), corrosion potential (E(corr)), pitting breakdown potential (E(b)), and the difference between E(corr) and E(b) representing the "pseudo-passivation" (ΔE) obtained from the electrochemical tests were used to evaluate the corrosion resistance of dental pure titanium. The data were statistically analyzed by 2×2 factorial statistical analysis to examine the effect of sodium fluoride and adhesion of Streptococcus mutans using SPSS 12.0 software package. The results showed that the corrosion parameters including R(ct), Ecorr, E(b), and ΔE of pure titanium had significant difference between before and after adhesion of Streptococcus mutans in the same solution(P<0.05), and in artificial saliva with 0 g/L and 1.0 g/L sodium fluoride(P<0.05). The dental pure titanium was prone to corrosion in artificial saliva with sodium fluoride. The corrosion resistance of pure titanium decreased distinctly after immersed in culture medium with Streptococcus mutans.

Eosin is most widely used synthetic dye belonging to the xanthene group. These dyes are efficient but are hazardous to human and animal health. With the increasing awareness of a green earth, it is advisable to use more of eco-friendly and biodegradable material which can be effectively achieved by the use of natural dyes obtained from plants and other natural sources. Turmeric, available as Curcuma longa (domestic), has long been in use in the subcontinent as a spice and flavoring agent in most food preparations. Its health benefit as a natural antibiotic and anti-inflammatory has been successfully established by several researchers. The intense yellow color imparted by turmeric inspired us to explore its efficacy as a potential alternative for eosin in routine histopathological procedures. The aim of this was to explore the efficacy of turmeric extract as a stand-alone counterstain for hematoxylin and its comparative assessment with routine H and E staining. The rhizomes of C. longa were cut into small pieces, dried and milled. This powder was dissolved into alcohol and centrifuged using a centrifugal machine. The supernatant was then collected with the help of micropipette. This supernatant was used as a counterstain for hematoxylin. The data were analyzed using Mann-Whitney U test with Statistical Package for the Social Sciences version 15.0 (SPSS Inc.,). The P value obtained was statistically insignificant ( P > 0.05). Although eosin is the most efficient counterstain for hematoxylin, turmeric can also be used as an alternative for eosin.

To create and validate an instrument that identifies women's vulnerability to domestic violence through gender subordination indicators in the family. An instrument consisting on 61 phrases was created, that indicates gender subordination in the family. After the assessment from ten judges, 34 phrases were validated. The approved version was administered to 321 health service users of São José dos Pinhais (Estado de Paraná, Brasil), along with the validated Portuguese version of the Abuse Assessment Screen (AAS) (for purposes of separating the sample group - the ''YES'' group was composed of women who have suffered violence and the ''NO'' group consisted of women who had not suffered violence). Data were transferred into the Statistical Package for the Social Sciences (SPSS) software, version 22, and quantitatively analyzed using exploratory and factor analysis, and tests for internal consistency. After analysis (Kaiser-Meyer-Olkin (KMO) statistics, Monte Carlo Principal Components Analysis (PCA, and diagram segmentation), two factors were identified: F1 - consisting of phrases related to home maintenance and family structure; F2 - phrases intrinsic to the couple's relationship. For the statements that reinforce gender subordination, the mean of the factors were higher for the group that answered YES to one of the violence identifying issues. The created instrument was able to identify women who were vulnerable to domestic violence using gender subordination indicators. This could be an important tool for nurses and other professionals in multidisciplinary teams, in order to organize and plan actions to prevent violence against women.

BACKGROUND/OBJECTIVES This research analyzes the effects of the food choices of industrial workers according to their sugar intake pattern on their job satisfaction through the construction of a model on the relationship between sugar intake pattern and job satisfaction. SUBJECTS/METHODS Surveys were collected from May to July 2015. A statistical analysis of the 775 surveys from Kyungsangnam-do was conducted using SPSS13.0 for Windows and SEM was performed using the AMOS 5.0 statistics package. RESULTS The reliability of the data was confirmed by an exploratory factor analysis through a Cronbach's alpha coefficient, and the measurement model was proven to be appropriate by a confirmatory factor analysis in conjunction with AMOS. The results of factor analysis on food choice, sugar intake pattern and job satisfaction were categorized into five categories. The reliability of these findings was supported by a Cronbach's alpha coefficient of 0.6 and higher for all factors except confection (0.516) and dairy products (0.570). The multicollinearity results did not indicate a problem between the variables since the highest correlation coefficient was 0.494 (P < 0.01). In an attempt to study the sugar intake pattern in accordance with the food choices and job satisfaction of industrial workers, a structural equation model was constructed and analyzed. CONCLUSIONS All tests confirmed that the model satisfied the recommended levels for the goodness of fit index, and thus, the overall research model was proven to be appropriate. PMID:27478555

The aim of this study was to compare the achievement of prospective primary science teachers in a problem-based curriculum with those in a conventional primary science teacher preparation program with regard to success in learning about gases and developing positive attitudes towards chemistry. The subjects of the study were 101 first year undergraduate students, who were in two different classes and who were taught by the same lecturer. One of the classes was randomly selected as the intervention group in which problem-based learning (PBL) was used, and the other as the control in which conventional teaching methods were used. The data were obtained through use of the gases diagnostic test (GDT), the chemistry attitude scale (CAS), and scales specific to students’ evaluation of PBL such as the peer evaluation scale (PES), self evaluation scale (SES), tutor’s performance evaluation scale (TPES) and students’ evaluation of PBL scale (SEPBLS). Data were analysed using SPSS 10.0 (Statistical Package for Social Sciences). In order to find out the effect of the intervention (PBL) on students’ learning of gases, independent sample t-tests and ANCOVA (analysis of co-variance) were used. The results obtained from the study showed that there was a statistically significant difference between the experimental and control groups in terms of students’ GDT total mean scores and, their attitude towards chemistry, as well as PBL has a significant effect on the development of students’ skills such as self-directed learning, cooperative learning and critical thinking.

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.

Few studies have looked at the predictors of use of home sphygmomanometers among hypertensive patients in low-income countries such as Pakistan. Considering the importance of home blood pressure monitoring (HBPM), cross-sectional study was conducted to evaluate the prevalence and predictors of the usage of all kinds of HBPM devices. This study was conducted in Karachi during the time period of January-February 2017. Adult patients previously diagnosed with hypertension visiting tertiary care hospitals were selected for the study. Interviews from the individuals were conducted after verbal consent using a pre-coded questionnaire. The data was analyzed using Statistical Package for the Social Sciences v. 23.0 (SPSS, IBM Corporation, NY, USA). Chi-squared test was applied as the primary statistical test. More than half of the participants used a home sphygmomanometer (n=250, 61.7%). The age, level of education, family history of hypertension, compliance to drugs and blood pressure (BP) monitoring, few times a month at clinics were significant determinants of HBPM (P values < 0.001). It was found that more individuals owned a digital sphygmomanometer (n=128, 51.3%) as compared to a manual type (n=122, 48.8%). Moreover, avoiding BP measurement in a noisy environment was the most common precaution taken (n=117, 46.8%). The study showed that around 40% of the hypertensive individuals did not own a sphygmomanometer and less than 25% performed HBPM regularly. General awareness by healthcare professionals can be a possible factor which can increase HBPM.

Gastroesophageal reflux disease (GERD) is a common chronic gastrointestinal tract disease. The incidence is higher in Asian and Arab countries. In Saudi Arabia, there are few studies that have assessed the prevalence of GERD among some cities' communities. Hence, this study aims to study the prevalence of GERD among the general population of Saudi Arabia. A cross-sectional study was designed to determine the prevalence of GERD among the community of Saudi Arabia. The sample was randomly gathered through self-administered validated GERD questionnaire (GerdQ) to diagnose GERD, during the period from November to December 2016. The sociodemographic data was assessed for all participants. The data were analysed using Statistical Package for Social Sciences version 21.0 (SPSS); the t -test was used to assess the association of GERD and sociodemographic data. The sample was comprised of 2,043 participants. Female and male were 51.8% and 48.2%, respectively. Mean age was 29.6 years with the standard deviation of 10.5 years. The GERD prevalence was 28.7%. It was found statistically significant among divorced/widow (34.9%, P = 0.003). In contrast, there was no association between GERD's prevalence and gender, age, residence status, education level, occupation, and blood group (P > 0.05). The prevalence of GERD among Saudi population is higher than that in Western countries and East Asia. It affects divorced/widow, obese and those with a sedentary lifestyle. It is advocated that national programs and educational campaigns for prevention of this disease and its complications should be established.

There is some ambiguity concerning the do-not-resuscitate (DNR) orders in the Arabic world. DNR is an order written by a doctor, approved by the patient or patient surrogate, which instructs health care providers to not do CPR when cardiac or respiratory arrest occurs. Therefore, this research study investigated the attitudes of Intensive Care Unit physicians and nurses on DNR order in Palestine. A total of 123 males and females from four different hospitals voluntarily participated in this study by signing a consent form; which was approved by the Ethical Committee at Birzeit University and the Ministry of Health. A non-experimental, quantitative, descriptive, and co-relational method was used, the data collection was done by a three page form consisting of the consent form, demographical data, and 24 item-based questionnaire based on a 5-point-Likert scale from strongly agree (score 1) to strongly disagree (score 5). The Statistical Package for Social Sciences (SPSS) software program version 17.0 was used to analyze the data. Finding showed no significant relationship between culture and opinion regarding the DNR order, but religion did. There was statistical significance difference between the physicians' and nurses' religious beliefs, but there was no correlation. Moreover, a total of 79 (64.3%) physicians and nurses agreed with legalizing the DNR order in Palestine. There was a positive attitude towards the legalization of the DNR order in Palestine, and culture and religion did not have any affect towards their attitudes regarding the legalization in Palestine.

The premature loss of primary teeth may reduce arch length required for the succeeding tooth and, hence, predisposes crowding, rotation and impaction of the permanent teeth. There are only limited studies carried out about the prevalence of early loss of primary teeth. The present study was performed to evaluate the prevalence of early loss of primary teeth in school children in Chidambaram town in Tamilnadu, India. A total of 1121 school children (561 boys and 560 girls) between 5 and 10 years of age were selected for the study. An experienced examiner performed all clinical examinations under natural light. Data including age and missing tooth was collected. Microsoft Excel/2000 (Microsoft Office XP) data spreadsheet was used and later exported to the Statistical Package for Social Science (SPSS) for Windows (version 10.0). Descriptive statistics was applied and, from the results, chi-square tests were applied at a level of significance of 5% (P < 0.05). The results showed that 16.5% of the sample had early loss of primary teeth, but no differences were observed between genders (P > 0.05). The greatest prevalence was found among the 8-year olds (5.08%), and the most commonly missing teeth were the right lower primary first molars (16.82%). It can be concluded that the prevalence of early loss was high and that the lower primary molars were the most commonly missing teeth in the present study.

Obesity is a major risk factor for type 2 diabetes mellitus (T2DM). Clinical evidence indicates a stronger association of diabetes with central obesity than general obesity. The present study aimed to compare the association between type 2 diabetes mellitus and different anthropometric measurements and evaluate the usefulness of these measurements in clinical practice. A case-control study was done among 102 individuals; of whom 51 cases included diagnosed T2DM (≥ 20 years age) patients attending the Medicine out-patient consultation of a tertiary care hospital and 51 controls who were screen negative for T2DM and recruited from the local community. Various anthropometric measurements were used according to standard World Health Organization (WHO) protocols. Data was entered and analyzed using Statistical Package for Social Sciences (SPSS) version 15. The proportion of cases with Body Mass Index (BMI) ≥ 25 kg/m 2 was 55% as compared to 22% of controls and this association was statistically significant (p < 0.05). The proportion of cases with high waist circumference cut-offs (WC) was 74.5% as compared to 45.1% healthy individuals and this association was also statistically significant (p < 0.05, OR = 3.56). A Receiver Operating Characteristic (ROC) curve for both gender revealed highest area under the curve for body mass index (area = 0.787). Body mass index had the best discriminatory power. Waist to hip ratio was not a sensitive marker especially for females. A strong association between obesity indices and diabetes was identified. BMI and WC could be used in clinical practice for suggesting life style modifications.

The aim of this study was to explore post-treatment speech impairments using English version of Speech Handicap Index (SHI) (first speech-specific questionnaire) in a cohort of oral cavity (OC) and oropharyngeal (OP) cancer patients. Sixty-three consecutive OC and OP cancer patients in follow-up participated in this study. Descriptive analyses have been presented as percentages, while Mann-Whitney U-test and Kruskall-Wallis test have been used for the quantitative variables. Statistical Package for Social Science-15 statistical software (SPSS Inc., Chicago, IL) was used for the statistical analyses. Over a third (36.1%) of patients reported their speech as either average or bad. Speech intelligibility and articulation were the main speech concerns for 58.8% and 52.9% OC and 31.6% and 34.2% OP cancer patients, respectively. While feeling of incompetent and being less outgoing were the speech-related psychosocial concerns for 64.7% and 23.5% OC and 15.8% and 18.4% OP cancer patients, respectively. Worse speech outcomes were noted for oral tongue and base of tongue cancers vs. tonsillar cancers, mean (SD) values were 56.7 (31.3) and 52.0 (38.4) vs. 10.9 (14.8) (P<0.001) and late vs. early T stage cancers 65.0 (29.9) vs. 29.3 (32.7) (P<0.005). The English version of the SHI is a reliable, valid and useful tool for the evaluation of speech in HNC patients. Over one-third of OC and OP cancer patients reported speech problems in their day-do-day life. Advanced T-stage tumors affecting the oral tongue or base of tongue are particularly associated with poor speech outcomes. Copyright © 2012 Elsevier Ltd. All rights reserved.

Pain control is one of the most important aspects of behavior management in children. The most common way to achieve pain control is by using local anesthetics (LA). Many studies describe that the buccal nerve innervates the buccal gingiva and mucosa of the mandible for a variable extent from the vicinity of the lower third molar to the lower canine. Regarding the importance of appropriate and complete LA in child-behavior control, in this study, we examined the frequency of buccal gingiva anesthesia of primary mandibular molars and canine after inferior alveolar nerve block injection in 4- to 6-year-old children. In this descriptive cross-sectional study, 220 4- to 6-year-old children were randomly selected and entered into the study. Inferior alveolar nerve block was injected with the same method and standards for all children, and after ensuring the success of block injection, anesthesia of buccal mucosa of primary molars and canine was examined by stick test and reaction of child using sound, eye, motor (SEM) scale. The data from the study were analyzed using descriptive statistics and statistical software Statistical Package for the Social Sciences (SPSS) version 21. The area that was the highest nonanesthetized was recorded as in the distobuccal of the second primary molars. The area of the lowest nonanesthesia was also reported in the gingiva of primary canine tooth. According to this study, in 15 to 30% of cases, after inferior alveolar nerve block injection, the primary mandibular molars' buccal mucosa is not anesthetized.

HIV-related conditions are one of the indirect causes of maternal deaths in Zimbabwe and the prevalence rate was estimated to be 13.63% in 2009. The study utilised a descriptive correlational design on 80 pregnant women who were HIV positive at Mbuya Nehanda maternity hospital in Harare, Zimbabwe. Participants comprised a random sample of 80 postnatal mothers. Permission to carry out the study was obtained from the respective review boards. Participants signed an informed consent. Data were collected using a structured questionnaire and record review from 1 to 20 March 2012. Interviews were done in a private room and code numbers were used to identify the participants. Completed questionnaires were kept in a lockable cupboard and the researcher had sole access to them. Data were analysed using the Statistical Package for Social Sciences (SPSS) version 12. Descriptive statistics were used to analyse data on demographics, maternal health outcomes and self-care practices. Inferential statistics (Pearson's correlation and regression analysis) were used to analyse the relationship between self-care practices and maternal health outcomes. Self-care practices were good with a mean score of 8 out of 16. Majority (71.3%) fell within the good category. Maternal outcomes were poor with a mean score of 28 out of 62 and 67.5% falling in the poor category. Pearson's correlation indicated a weak significant positive relationship (r = .317, p = <.01). Regression analysis (R 2 ) was .10 implying that self-care practices explained 10% of the variance observed in maternal health outcomes. More research needs to be carried out to identify other variables affecting maternal outcomes in HIV-positive pregnant women.

Background: Recent epidemiological studies have shown that periodontal infection is a risk factor for a number of systemic diseases and conditions. In addition to the conventional risk factors, chronic infection and the subsequent generation of a systemic inflammatory response may be associated with this increased risk. Aims: This study was conducted to determine whether the presence of chronic periodontitis and subsequent non-surgical periodontal therapy could influence the serum levels of interleukin-6 and C-reactive protein (CRP) in patients with severe chronic generalized periodontitis. Settings and Design: Participants were selected from subjects who attended the Department of Periodontics and Oral Implantololgy, Government Dental College, Thiruvananthapuram. Materials and Methods: Sera were obtained from 25 patients with periodontitis for baseline examination and reassessment after completion of treatment. As a control, sera were also obtained from 20 subjects without periodontitis. Interleukin-6 was determined by sensitive enzyme-linked immunosorbent assay, and high-sensitivity CRP (hsCRP) was measured using latex turbidometric immunoassay. Statistical Analysis: Data were analyzed using computer software, Statistical Package for Social Sciences (SPSS) version 10. Results: The level of interleukin-6 and hsCRP in the sera of periodontitis patients was seen to be higher than those of healthy controls. Interleukin-6 level tended to decrease with improvement of the periodontal condition following treatment and approached that of control subjects, and this decline was statistically significant. The hsCRP levels also showed a decreasing trend following periodontal treatment. Conclusions: In this study, we were able to show that periodontal disease significantly affects the serum levels of systemic inflammatory markers and that non-surgical periodontal therapy could bring about a decrease in the levels of these inflammatory markers.

The aim of this study was to determine the effects of nociceptin/orphanin FQ peptide receptor (N/OFQ receptor) antagonist on orofacial pain induced by experimental tooth movement in rats. A total of 36 male Sprague-Dawley rats weighing 200-300 g were divided into six groups: a control group, force group, force+saline intraperitoneal group, force+saline periodontal group, force+UFP-101 ([Nphe¹,Arg¹⁴,Lys¹⁵]N/OFQ-NH ₂ antagonist for N/OFQ receptor) intraperitoneal group, and force+UFP-1 01 periodontal group. Closed coil springs were ligated between the upper incisors and first molar to exert an orthodontic force (40 g) between the teeth. Injectable administration dosages were 30 μl saline or 30 μl saline containing 0.03 mg/kg UFP-1 01. Following the injections, orofacial pain levels were assessed through directed face grooming (mouth wiping). Statistical analyses were performed in SPSS 17.0 (Statistical Package for the Social Sciences) and p values less than 0.05 were considered as statistically significant. Orofacial pain levels were significantly higher in the force group than in the control group. Orofacial pain levels differed significantly between the force)group, force+saline periodontal group and force+UFP-101 periodontal group, but were similar between the control group, force+UFP-101 intraperitoneal group and force+saline intraperitoneal group. Moreover, orofacial pain levels did not differ between the force group, force+saline intraperitoneal group and force+UFP-1 01 intraperitoneal group. Periodontal, but not intraperitoneal, administration of UFP-101 could alleviate orofacial pain induced by experimental tooth movement in rats, suggesting that periodontal N/OFQ receptors participate in orofacial pain induced by experimental tooth movement.

Pesticide poisoning is a common occurrence around the world. Pesticides can act on various body systems resulting in toxicity. Flubendiamide is a new generation pesticide, reported to have better activity against Lepidopteran insects. The present study was carried out with an objective to analyze the effects of flubendiamide sub-acute exposure on hematology of rats. Male and female Sprague Dawley (SD) rats (9-11 weeks) were divided into five groups with six animals in each group. First group served as control, while the rest were exposed to ascending oral doses of flubendiamide (125, 250, 500 and 1000 mg/kg) for 28 days. After the trial period, blood was collected in heparinized vials and analyzed using Siemens ADVIA 2120(®) autoanalyzer. Various erythrocytic, platelet and leukocyte parameters were measured and analyzed using statistical tests by one-way analysis of variance (ANOVA) and t-test using Statistical Package for Social Sciences (SPSS)(®) 20 software. After processing the data through statistical analysis, it was observed that the effect of flubendiamide exposure on female rats was negligible. The only significant change observed in the female rats was that in total erythrocytic count, while rest of the parameters showed non-significant bidirectional changes. In males, many parameters viz., total leukocyte count (TLC), total erythrocyte count (TEC), packed cell volume (PCV), mean corpuscular volume (MCV), platelet count (PC), mean platelet volume (MPV), platelet distribution width (PDW), hemoglobin distribution width (HDW), large platelets (LPT) and plateletcrit (PCT) expressed significant difference when compared to control. Many of the changes were dose independent, but sex specific. This lead to the hypothesis that saturation toxicokinetics might be one of the reasons for this varied response, which can only be evaluated after further testing.

Objective: To assess the awareness and attitude of the general public toward people living with HIV/AIDS (PLWHA) in Mangalore, a city in Coastal Karnataka. Design: Community-based cross-sectional study. Materials and Methods: The study population included 630 individuals aged 18 years and above. The information was collected using a semi structured pre-tested questionnaire. The questionnaire consisted of 24 questions regarding awareness of the modes of transmission of HIV/AIDS (nine questions) and questions to assess the attitude toward People Living With HIV/AIDS (PLWHA) (15 questions). Statistical package SPSS version 11.5 was used, Chi-square test was conducted and P < 0.05 was considered as statistically significant. Results: About one-third of the study population thought that one could get infected by merely touching an HIV positive individual. Approximately 45% stated that they would dismiss their maid on finding out her HIV positive status. About 54% were willing to undergo the HIV test. The respondents with less than secondary school education had a discriminatory attitude toward HIV positive people, with regard to them deserving to suffer, dismissing a HIV positive maid, hesitating to sit next to a HIV positive person in the bus, divorcing the infected spouse, and willingness to get tested for HIV, which was found to be statistically significant. Conclusion: Stigma among the general public was mostly due to fear of contracting the illness. Stigma does exist to significant degrees among the educated people, which was suggested by about 45% of the participants being willing to undergo the HIV test. There is a need for greater attempts toward making information regarding HIV/AIDS available to every individual of the society. PMID:20606940

Background: One of the most important challenges of Iranian health care system is “quality of care,” and it is assumed that motivated nurses are more ready to provide better care. There are limited studies investigating Iranian nurses’ motivations; however, factors which motivate them have not been studied yet. Identifying the motivating factors enables nurse managers to inspire nurses for continuous quality improvement. The aim of this study was to identify motivating factors for Iranian hospital nurses. Materials and Methods: This is a cross-sectional descriptive study in which 310 nurses working at 14 hospitals of Tehran University of Medical Sciences were selected by proportionate stratified random sampling. Data were collected in 2010 by a researcher-developed questionnaire. Descriptive statistics and independent t-test, analysis of variance, Tukey post-hoc test, Chi-Square and Fisher's exact test were used for statistical analysis by Statistical Package for Social Sciences (SPSS) version 16. Results: The mean score of motivation was 90.53 ± 10.76 (range: 59–121). Four motivating factors including “career development” (22.63 ± 5.66), “job characteristics” (34.29 ± 4), “job authority” (18.48 ± 2.79), and “recognition” (15.12 ± 2.5) were recognized. The least mean of the motivation score, considering the number of items, was 3.23 for career development, while the highest mean was 3.81 for job characteristics. Conclusions: The findings showed that motivation of nurses was at a medium level, which calls for improvement. The factors that have the greatest potential to motivate nurses were identified in this study and they can help managers to achieve the goal of continuous quality improvement. PMID:26257797

An estimated 95% of the population of Ethiopia uses traditional biomass fuels, such as wood, dung, charcoal, or crop residues, to meet household energy needs. As a result of the harmful smoke emitted from the combustion of biomass fuels, indoor air pollution is responsible for more than 50,000 deaths annually and causes nearly 5% of the burden of disease in Ethiopia. Very limited research on indoor air pollution and its health impacts exists in Ethiopia. This study was, therefore, undertaken to assess the magnitude of indoor air pollution from household fuel use in Addis Ababa, the capital city of Ethiopia. During January and February, 2012, the concentration of fine particulate matter (PM2.5) in 59 households was measured using the University of California at Berkeley Particle Monitor (UCB PM). The raw data was analysed using Statistical Package of Social Science (SPSS version 20.0) software to determine variance between groups and descriptive statistics. The geometric mean of 24-h indoor PM2.5 concentration is approximately 818 μg m-3 (Standard deviation (SD = 3.61)). The highest 24-h geometric mean of PM2.5 concentration observed were 1134 μg m-3 (SD = 3.36), 637 μg m-3 (SD = 4.44), and 335 μg m-3 (SD = 2.51), respectively, in households using predominantly solid fuel, kerosene, and clean fuel. Although 24-h mean PM2.5 concentration between fuel types differed statistically (P < 0.05), post hoc pairwise comparison indicated no significant difference in mean concentration of PM2.5 between improved biomass stoves and traditional stoves (P > 0.05). The study revealed indoor air pollution is a major environmental and health hazard from home using biomass fuel in Addis Ababa. The use of clean fuels and efficient cooking stoves is recommended.

Even with current highly active antiretroviral therapy, individuals with AIDS continue to exhibit important nutritional deficits and reduced levels of albumin and hemoglobin, which may be directly related to their cluster of differentiation 4 (CD4) cell counts. The aim of this study was to characterize the nutritional status of individuals with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and relate the findings to the albumin level, hemoglobin level and CD4 cell count. Patients over 20 years of age with AIDS who were hospitalized in a university hospital and were receiving antiretroviral therapy were studied with regard to clinical, anthropometric, biochemical and sociodemographic characteristics. Body mass index, percentage of weight loss, arm circumference, triceps skinfold and arm muscle circumference were analyzed. Data on albumin, hemoglobin, hematocrit and CD4 cell count were obtained from patient charts. Statistical analysis was performed using Fisher's exact test, Student's t-test for independent variables and the Mann-Whitney U-test. The level of significance was set to 0.05 (α = 5%). Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) 17.0 software for Windows. Of the 50 patients evaluated, 70% were male. The prevalence of malnutrition was higher when the definition was based on arm circumference and triceps skinfold measurement. The concentrations of all biochemical variables were significantly lower among patients with a body mass index of less than 18.5kg/m2. The CD4 cell count, albumin, hemoglobin and hematocrit anthropometric measures were directly related to each other. These findings underscore the importance of nutritional follow-up for underweight patients with AIDS, as nutritional status proved to be related to important biochemical alterations.

Human papilloma viruses (HPVs) are small DNA viruses that have been identified in periodontal pocket as well as gingival sulcus. High risk HPVs are also associated with a subset of head and neck carcinomas. It is thought that the periodontium could be a reservoir for HPV. 1. Detection of Human Papilloma virus (HPV) in periodontal pocket as well as gingival of patients having localized chronic periodontitis and gingival sulcus of periodontally healthy subjects. 2. Quantitative estimation of E6 and E7 mRNA in subjects showing presence of HPV3. To assess whether periodontal pocket is a reservoir for HPV. This case-control study included 30 subjects with localized chronic Periodontitis (cases) and 30 periodontally healthy subjects (controls). Two samples were taken from cases, one from periodontal pocket and one from gingival sulcus and one sample was taken from controls. Samples were collected in the form of pocket scrapings and gingival sulcus scrapings from cases and controls respectively. These samples were sent in storage media for identification and estimation of E6/E7 mRNA of HPV using in situ hybridization and flow cytometry. Statistical analysis was done by using, mean, percentage and Chi Square test. A statistical package SPSS version 13.0 was used to analyze the data. P value < 0.05 was considered as statistically significant. pocket samples as well as sulcus samples for both cases and controls were found to contain HPV E6/E7 mRNAInterpretation and. Presence of HPV E6/E7 mRNA in periodontium supports the hypothesis that periodontal tissues serve as a reservoir for latent HPV and there may be a synergy between oral cancer, periodontitis and HPV. However prospective studies are required to further explore this link.

To evaluate the correlation between the number of leukocytes and cardiovascular risks associated with birth characteristics, nutritional status and biochemical tests. 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. 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. 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.

Psychiatric co-morbidities are frequent among patients attending dental OPD, some of which go unrecognized and hence untreated. The present study has been carried out to detect the psychiatric co-morbidities among dental patients and determine the scope of consultation-liaison (C-L) psychiatry in a rural teaching hospital regarding comprehensive management of the patients. This cross-sectional, descriptive type study was conducted in a multi-speciality tertiary care teaching hospital in the northern part of West Bengal, India. One hundred patients attending the dental OPD were randomly included in the study and every patient was consecutively referred to psychiatry department for assessment, during the period from 1(st) November 2013 to 30(th) April 2014. All referred patients were clinically examined and psychiatric co-morbidity was assessed by the help of General Health Questionnaire (GHQ)-28 and Mental Status Examination. The data were subjected to statistical package for social sciences (SPSS), version 16, and statistically analyzed using Cross tab and Chi test. P <0.05 was considered to be statistically significant. The commonest dental illness was dental caries (22%). More than two-third of the patients had psychiatric co-morbidity according to GHQ-28 total score. Sixty-eight patients were diagnosed to have mental disorder on mental status examination. Somatoform disorder (25%) was the commonest type of mental disorder, followed by mixed anxiety and depression (14%). This study has pointed the need for psychological examination of patients visiting dental specialty with unexplained physical symptoms. Such patients can be identified and treated, provided a psychiatric consultation service exists.

Many doctors are leaving Nepal to work abroad. To understand this problem better, we decided to study the attitude and plans of young doctors and medical students. This cross-sectional study was conducted at Kathmandu Medical College involving 65 first year medical students, 100 interns and 100 house officers. The data collected was entered in Microsoft excel and analysed by SPSS (Statistical Package for Social Sciences) programme. Chi-square test was used to compare two proportions. Significance level was set at 5%. Only 2% house officers said that their job prospects were excellent as compared to 22.4% of students, whereas 20% house officers as compared to 9% students thought job prospects in Nepal were poor (p= 0.003). Eighty two percent of students thought that a doctor's service to his country was very important as compared to 51% of interns (p= 0.001) and 58% of house officers. Forty percent of students, 58% of interns and 48% of house officers (no statistical significance between the three groups) planned to migrate to a developed country after graduation. Eighty eight percent of students, 89% interns and 74% of house officers (no statistical significant differences between the three groups) were of the opinion that improving career opportunities or working environment of the doctor could make the profession more attractive. Although majority of students, interns and house officers were of the opinion that a doctor's service to his community/country was very important, almost half of them still planned to migrate to a developed country after graduation. Improving the chances of professional advancement and professional working environment can make the profession more attractive, and therefore, may decrease this tendency for brain drain from our country.

Background: Snoring remains under diagnosed in general population. It however has significant morbidity and mortality risk factors with multiple effects on the cardiovascular system. The Berlin questionnaire is a worldwide validated instrument to identify those at increased risk for obstructive sleep apnoea (OSA). Materials and Methods: In all, 206 workers of LAUTECH were invited to participate in the study. The Berlin questionnaire was used for this study. It was a cross-sectional study. Socio-demographic and clinical data were taken with a data form. Statistical Package for the Social Sciences software (SPSS 17.0) was used for statistical analysis. P < 0.05 was taken as statistically significant value. Results: The study participants consisted of 96 males (46.6%) and 110 (53.4%) females. The mean age was 45.3 ± 7.9 years. The mean body mass index was 28.5 ± 6.0 kg/m². The frequency of occurrence of snoring was 91 (44.2%) including 50 males (54.9% and 41 females (37.3 %, P <0.05). Using the Berlin score, 63 (30.6%) including 34 females (30.9%) were assessed to be at high risk for OSA. Snorers were more likely to be at higher risk of OSA compared to non snorers: odd risk was 113.8, relative risk was 3.3. Snoring was most likely to be associated with obesity, elevated blood pressure and male gender in this study. Conclusion: We concluded that snoring and high risk for sleep apnoea is common among this unselected University population and they are closely related to many conventional cardiovascular risk factors. Appropriate interventional strategies are indicated to reduce the burden of the increased morbidity and mortality associated with sleep apnoea in our population. PMID:25538364

Toothbrushes in regular use can become heavily contaminated with microorganisms, which can cause infection or reinfection. There is a need for toothbrush disinfection methods, which are rapidly effective, cost-effective, nontoxic, and that can be easily implemented. To compare the efficacy of 3% neem, garlic of concentration 4.15 mg/mL and green tea of concentration 40 mg/mL with 0.2% chlorhexidine mouthwash as toothbrush disinfectants. The study was a parallel in vitro comparative experimental trial conducted among 75 randomly selected boys aged between 18 years and 21 years. The subjects were divided into five groups, namely, Group I, Group II, Group III, Group IV, and Group V. They were provided with a new set of precoded toothbrushes and nonfluoridated tooth pastes. After 14 days of tooth brushing, the toothbrushes were immersed in antimicrobial solution for 12 h [Group I--distilled water (control), Group II--3% neem, Group III--garlic of concentration 4.15 mg/mL, Group IV--green tea of concentration 40 mg/mL, and Group V--0.2% chlorhexidine] and then subjected to microbial analysis to check the presence of Streptococcus mutans. The t-test and analysis of variance (ANOVA) were done using Statistical Package for the Social Sciences (SPSS) software version 16. All test solutions showed a statistically significant reduction of Streptococcus mutans count (P < 0.001). There was no statistical difference between the efficacies of neem, garlic, and green tea when compared with chlorhexidine mouthwash (P > 0.05). Neem, garlic, and green tea are equally efficacious as chlorhexidine and these herbal products can be used as potent alternatives to chlorhexidine as disinfectant for toothbrushes.

The incidence of breast cancer is rapidly increasing in Yemen with recent indications of constituting one-third of female cancers. The main problem in Yemen remains very late presentation of breast cancer, most of which should have been easily recognisable. Since stage of disease at diagnosis is the most important prognostic variable, early diagnosis is an important option to be considered for control of breast cancer in low resourced settings like Yemen. In the present study, we aimed at describing breast cancer knowledge, perceptions and breast self-examination (BSE) practices among a sample of Yemeni women. This cross-sectional study covered 400 women attending four reproductive health centres in Aden, Yemen through face-to-face interview using a structured questionnaire during April - July 2014. We collected data on sociodemographic characteristics, knowledge about breast cancer, and screening practices as well as respondents' perceptions based on the five sub scales of the Health Belief Model (HBM): perceived susceptibility; perceived severity; perceived barriers; perceived benefits; and self-efficacy. The response format was a fivepoint Likert scale. Statistical Package for Social Sciences (SPSS 20) was used for statistical analysis. Statistical significance was set at p<0.05. Logistic regression analysis was conducted with BSE as a dependent variable. The mean age of women was 26.5 (S.D=5.6) years. The majority (89.0%) had never ever performed any screening. Two-thirds of respondents had poor knowledge. Perceived BSE benefits and self-efficacy and lower BSE barriers perception were significant independent predictors of BSE practice. Poor knowledge and inadequate BSE practices are prevailing in Yemen. The need for implementing culturally sensitive targeted education measures is mandatory in the effort to improve early detection and reduce the burden of breast cancer.

Design and statistical problems in prevention.

Clinical and epidemiological research in osteoporosis can benefit from using the methods and techniques established in the area of chronic disease epidemiology. However, attention has to be given to the special characteristics such as the multifactorial nature and the fact that the subjects usually are of high ages. In order to evaluate prevention it is of course first necessary to detect and confirm reversible risk factors. The advantage and disadvantage of different design (cross-sectional, cohort and case-control) are well known. The effects of avoidable biases, e.g. selection, observation and confounding have to be balanced against practical conveniences like time, expenses, recruitment etc. The translation of relative risks into population attributable risks (etiologic fractions, prevented fractions) are complex and are usually performed under unrealistic, simplified assumptions. The consequences of interactions (synergy) between risk factors are often neglected. The multifactorial structure requires application of more advanced multi-level statistical techniques. The common strategy in prevention to target a cluster of risk factors in order to avoid the multifactorial nature implies that in the end it is impossible to separate each unique factor. Experimental designs for evaluating prevention like clinical trials and intervention have to take into account the distinction between explanatory and pragmatic studies. An explanatory approach is similar to an idealized laboratory trial while the pragmatic design is more realistic, practical and has a general public health perspective. The statistical techniques to be used in osteoporosis research are implemented in easy available computer-packages like SAS, SPSS, BMDP and GLIM. In addition to the traditional logistic regression methods like Cox analysis and Poisson regression also analysis of repeated measurement and cluster analysis are relevant.

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.

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.

BACKGROUND: Childbirth self-efficacy is one of the most important factors causing a shift in mothers do vaginal delivery. If the mother feels that she can cope well with stress, will be protected from the harmful effects of stress on your health. Self-efficacy contained individual's assessment of her ability to deal with stressful situations. Strengthen the spiritual beliefs of the patient causes her to be a good result every situation even incurable condition. This study aimed to determine the effect of religious-spiritual support on childbirth self-efficacy in primiparous women. METHODS: This is a quasi-experimental study carried on seventy primiparous women; participants were randomly divided into two intervention and control groups. The intervention group received the e-learning package based on religious-spiritual content. Self-efficacy questionnaire by both groups before and 4 weeks after it was completed. Collected data were entered into SPSS version 11 descriptive statistics, independent t-test, and paired t-test which were used for analysis of data. The significant level was considered <0.05. RESULTS: The results showed that the mean self-efficacy score before and after intervention in case group was 105.2 (27.01) and 110.12 (21.2), respectively, and in control group; 111.2 (23.12) and 116.9 (24.43). Paired t-test in two groups was significant (P = 0.042, P = 0.045) but independent t-test showed no significant difference in scores of childbirth self-efficacy before and after intervention in two groups (P = 0.061). CONCLUSION: In prenatal periods, religious-spiritual support through electronic package method can increase childbirth self-efficacy, so the planning and establishment of this training are recommended as an effective training.

One of the cornerstones of the R system for statistical computing is the multitude of packages contributed by numerous package authors. This amount of packages makes an extremely broad range of statistical techniques and other quantitative methods freely available. Thus far, no empirical study has investigated psychological factors that drive authors to participate in the R project. This article presents a study of R package authors, collecting data on different types of participation (number of packages, participation in mailing lists, participation in conferences), three psychological scales (types of motivation, psychological values, and work design characteristics), and various socio-demographic factors. The data are analyzed using item response models and subsequent generalized linear models, showing that the most important determinants for participation are a hybrid form of motivation and the social characteristics of the work design. Other factors are found to have less impact or influence only specific aspects of participation. PMID:26554005

One of the cornerstones of the R system for statistical computing is the multitude of packages contributed by numerous package authors. This amount of packages makes an extremely broad range of statistical techniques and other quantitative methods freely available. Thus far, no empirical study has investigated psychological factors that drive authors to participate in the R project. This article presents a study of R package authors, collecting data on different types of participation (number of packages, participation in mailing lists, participation in conferences), three psychological scales (types of motivation, psychological values, and work design characteristics), and various socio-demographic factors. The data are analyzed using item response models and subsequent generalized linear models, showing that the most important determinants for participation are a hybrid form of motivation and the social characteristics of the work design. Other factors are found to have less impact or influence only specific aspects of participation.

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

Summary The generalized linear mixed-effects model (GLMM) is a popular paradigm to extend models for cross-sectional data to a longitudinal setting. When applied to modeling binary responses, different software packages and even different procedures within a package may give quite different results. In this report, we describe the statistical approaches that underlie these different procedures and discuss their strengths and weaknesses when applied to fit correlated binary responses. We then illustrate these considerations by applying these procedures implemented in some popular software packages to simulated and real study data. Our simulation results indicate a lack of reliability for most of the procedures considered, which carries significant implications for applying such popular software packages in practice.

Logistic Regression with Multiple Random Effects: A Simulation Study of Estimation Methods and Statistical Packages

PubMed Central

Kim, Yoonsang; Emery, Sherry

2013-01-01

Several statistical packages are capable of estimating generalized linear mixed models and these packages provide one or more of three estimation methods: penalized quasi-likelihood, Laplace, and Gauss-Hermite. Many studies have investigated these methods’ performance for the mixed-effects logistic regression model. However, the authors focused on models with one or two random effects and assumed a simple covariance structure between them, which may not be realistic. When there are multiple correlated random effects in a model, the computation becomes intensive, and often an algorithm fails to converge. Moreover, in our analysis of smoking status and exposure to anti-tobacco advertisements, we have observed that when a model included multiple random effects, parameter estimates varied considerably from one statistical package to another even when using the same estimation method. This article presents a comprehensive review of the advantages and disadvantages of each estimation method. In addition, we compare the performances of the three methods across statistical packages via simulation, which involves two- and three-level logistic regression models with at least three correlated random effects. We apply our findings to a real dataset. Our results suggest that two packages—SAS GLIMMIX Laplace and SuperMix Gaussian quadrature—perform well in terms of accuracy, precision, convergence rates, and computing speed. We also discuss the strengths and weaknesses of the two packages in regard to sample sizes. PMID:24288415

To identify the profile of women seen in a Fetal Medicine unit, diagnosed with fetal abnormality incompatible with neonatal survival in their current pregnancy, and to check the association of gestational age upon diagnosis with the option of pregnancy termination. This is a retrospective cohort study carried out in the Fetal Medicine Outpatients Clinic of a university hospital, in the city of São Paulo (SP), Brazil, using medical records of pregnant women with fetus presenting abnormalities incompatible with neonatal survival. The sample comprised 94 medical records. The Statistical Package for the Social Sciences (SPSS), version 19, was used for the data statistical analysis. The population of the study included young adult women, who had complete or incomplete high school education, employed, with family income of one to three minimum wages, single, nonsmokers, who did not drink alcoholic beverages or used illicit drugs. Women with more advanced gestational age upon fetal diagnosis (p=0.0066) and/or upon admission to the specialized unit (p=0.0018) presented a lower percentage of termination of pregnancy. Due to characteristics different from those classically considered as of high gestational risk, these women might not be easily identified during the classification of gestational risk, what may contribute to a late diagnosis of fetal diseases. Early diagnosis enables access to specialized multiprofessional care in the proper time for couple's counseling on the possibility of requesting legal authorization for pregnancy termination. Identificar o perfil de mulheres atendidas em um serviço de Medicina Fetal, que receberam diagnóstico de anomalia fetal incompatível com a sobrevida neonatal na gestação atual, e verificar a associação da idade gestacional no diagnóstico com a opção pela interrupção da gravidez. Trata-se de um estudo de coorte retrospectivo, realizado no ambulatório de Medicina Fetal de um hospital universitário da cidade de São Paulo (SP), com prontuários de mulheres com fetos portadores de anomalias incompatíveis com a sobrevida neonatal na gestação atual. A amostra constituiu-se de 94 prontuários. Para análise estatística dos dados, utilizou-se o programa Statistical Package for the Social Sciences (SPSS), versão 19. A população foi de mulheres adultas jovens, com escolaridade compatível com o Ensino Médio completo/incompleto, empregadas, com renda familiar entre um e três salários mínimo, solteiras, que não faziam uso de tabaco, bebidas alcoólicas ou de drogas ilícitas. Verificou-se que mulheres com maior idade gestacional na ocasião do diagnóstico fetal (p=0,0066) e/ou na chegada ao serviço especializado (p=0,0018) apresentaram menor percentual de interrupção gestacional. Por apresentarem características diferentes daquelas classicamente consideradas de alto risco gestacional, é possível que essas mulheres não tenham sido facilmente identificadas durante a classificação de risco gestacional, o que pode ter colaborado para o diagnóstico tardio de patologias fetais. O diagnóstico precoce possibilita acesso à assistência multiprofissional especializada em tempo adequado para aconselhamento do casal sobre a possibilidade de solicitação de autorização judicial para a interrupção gestacional.

Background: Although, antenatal care (ANC) attendance in sub Saharan Africa is high, however this does not always translate into quality ANC care service utilization. Aim: This study therefore is aimed at exploring pattern of maternal health (MH) services utilization and the socio-demographic factors influencing it in Anambra State, South East Nigeria. Subjects and Methods: A total of 310 women of reproductive age with a previous history of gestation attending ANC services between September, 2007 and August, 2008 in selected Primary Health Centers in Anambra State were studied. Responses were elicited from the study participants using a pre-tested, semi-structured interviewer-administered questionnaire. Data collected were analyzed using Statistical Package for Social Sciences (SPSS) version 17 (SPSS Inc, Chicago Illinois, USA). Association between socio-demographic characteristics and pattern of utilization of ANC and delivery services was measured using χ2-test, Regression analysis was done to identify factors associated with utilization of MH services. P < 0.05 was assumed to be significant. Results: Use of health facility was 293 (97.0%) and 277 (92,7%) out 302 women for ANC and delivery services respectively. Most women attended their first ANC consultation during the preceding pregnancy was after the first trimester and about 31% (94/298) of them had <4 ANC visits prior to delivery. Socio-demographic factors were found to be significantly associated with places where MH care services are accessed. Parity was found to be associated with timing of ANC booking and number of ANC attendance (χ2 = 9.49, P = 0.05). Odds of utilizing formal health facility for MH services were found to be significantly associated with increasing age (P < 0.01) and educational status of mothers (P < 0.001). Conclusions: The study revealed high maternal service utilization and 10% fetal loss, hence the need to address the gaps of late ANC booking and low ANC visits. PMID:24971212

Premenstrual syndrome (PMS) is used to describe physical, cognitive, affective, and behavioral symptoms that occur cyclically during the luteal phase of the menstrual cycle and resolve quickly at or within a few days of the onset of menstruation. The primary aim of the study was to assess the prevalence, impacts and medical managements of PMS on female medical students of Mekelle University College of Health Sciences. A cross-sectional study was conducted among systematically selected female students of Mekelle University College of Health Sciences, Mekelle town, northern Ethiopia from March to April 2013. A structured and pretested self-administered questionnaire was employed for data collection. The collected data were analyzed using the Statistical Package for the Social Sciences, SPSS Inc., Chicago, IL (SPSS version 16). The criteria proposed by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV TR) were used to diagnose PMS. From the total population size of 608; a sample size of 258 was drawn. Age of the study participants ranged from 18 to 25 years, with mean age of 20.86 ± 1.913 years. Among the participants, 144(83.2%) have had at least one PM symptoms with their menstrual period. The prevalence of PMS according to DSM-IV was 37.0%. About 49(28.3%) reported frequent class missing, 17(9.8%) exam missing, 14(8.1%) low grade scoring and 3(1.7%) of them reported withdrawal from their learning associated with their PMS. Only 83(48.0%) participants sought medical treatment for their PMS. The treatment modalities used were pain killers, 63(36.4%), hot drinks like coffee and tea, 13(7.5%), and massage therapy and exercise, 7(4.0%). Binary logistic regression analysis revealed average length of one cycle of menstruation (COR = 0.20(0.070-0.569) and academic performance impairment (AOR = 0.345(0.183-0.653) were significantly associated with the diagnosis of PMS and use of PMS treatments respectively. Our study revealed a high prevalence and negative impact of PMS on students of Mekelle University. Therefore, health education, appropriate medical treatment and counseling services, as part of the overall health service, should be availed and provided to affected women.

2013-10-01

A cross-sectional survey of community pharmacists in Riyadh region, Saudi Arabia was conducted over a period of 6 months from July through December 2011. Data collection was carried out using a structured self-administered questionnaire. The survey questionnaire consisted of a brief introduction to the study and eleven questions. The questions consisted of close ended, multiple-choice, and fill-in short answers. A stratified random sample of one thousand and seven hundred registered pharmacy practitioners all over Saudi Arabia were randomly chosen to respond to the survey. The data from each of the returned questionnaire were coded and entered into Statistical Package for the Social Sciences (SPSS) version 19 software (SPSS Inc., Chicago, IL, USA) which was used for statistical analysis. Only one thousand four hundred one pharmacists responded to the survey (response rate is 82.4%) with a completely answered questionnaire. The study results show that 59.7% of the participants sometimes discuss herbal medicine use with their patients, while only 4.25% never discuss it. The study shows 48.5% of participated pharmacists record herbal medicine use sometimes where only 9.4% of them never did so. However, with regard to initiation of the discussion, the study shows that 44.3% of the respondents reported that patients initiate herbal issue discussion while 20.8% reported that pharmacists initiate the discussion. This discussion was reported to be a one time discussion or an ongoing discussion by 14.3% or 9.9% of the respondents respectively. According to the study results, respondents reported that the most common barriers that limit discussing herbal medicines' use with their patients were lack of time due to other obligations assigned to the community pharmacist (46%), lack of reliable resources (30.3%), lack of scientific evidence that support herbal medicine use (15.2%), or lack of knowledge of herbal medicines (13.4%). Yet, a small number of respondents was concerned about interest in herbal medicines (9.1%) and other reasons (2.4%). So it is urgent to ensure that pharmacists are appropriately educated and trained. Extra efforts are needed to increase the awareness of pharmacists to adverse drug reactions reporting system at Saudi Food and Drug Authority. Finally, more consideration to herbal issues should be addressed in both pharmacy colleges' curricula and continuous education program..

Purpose: We reported on the clinical approaches of ophthalmology and otorhinolaryngology departments in the treatment of the orbital complications of sinusitis. We also included an in-depth literature review. Methods: We retrospectively reviewed the medical files of 51 patients from January 2008 to January 2014. The records were evaluated for age, gender, type of orbital complications, symptoms, predisposing factors, imaging studies, medical and surgical management, culture results, and follow-up information. SPSS version 15.0 software (Statistical Analysis, The Statistical Package for Social Sciences Inc, Chicago, IL) was used for the statistical analysis. Results: Fifty-one patients met the criteria, with available medical records, for the study (29 male, 22 female). Thirty-two (62.7%) were diagnosed with preseptal cellulitis and 19 (37.3%) with postseptal cellulitis. After a detailed evaluation, 15 were diagnosed with a subperiosteal abscess (SPA), and 4 were diagnosed with orbital cellulitis. The age and gender was similar for the two groups. Five patients with medial SPA were treated with endoscopic sinus surgery, one patient with inferior SPA was treated with external surgery, and six patients with other localizations were treated with a combination of endoscopic sinus surgery and external surgery. All patients presented with periorbital erythema and edema. The length of hospitalization and duration of symptoms were similar in both groups. Visual acuity was between 1/10 to 10/10 (mean 7/10) and statistically significant for preseptal and postseptal cellulitis groups (p<0.001). All patients received intravenous antibiotics upon the first day of admission. Conclusion: Orbital complications of acute sinusitis required intensive follow-up and a multidisciplinary approach. A contrast-enhanced paranasal sinus computerized tomography (CT) scan can detect the extent of the infection. An initial trial of intravenosus (IV) antibiotics may be appropriate when close monitoring is possible. Surgery may be indicated when there has been no improvement within 48 hours of intravenous treatment, loss of visual acuity (under 8/10), and a non-medial abscess.

The partial pressure of venous to arterial carbon dioxide gradient (PCO 2 gap) is considered as an alternative marker of tissue hypoperfusion and has been used to guide treatment for shock. The aim of this study was to investigate the prognostic value of venous-to-arterial carbon dioxide difference during early resuscitation of patients with septic shock and compared it with that of lactate clearance and Acute Physiology and Chronic Health Evaluation II (APACHE-II) score. Forty patients admitted to one Intensive Care Unit were enrolled. APACHE-II score was calculated on admission. An arterial blood gas, central venous, and lactate samples were obtained on admission and after 6 h, and lactate clearance was calculated. Patients were classified retrospectively into Group I (survivors) and Group II (nonsurvivors). Pv-aCO 2 difference in the two groups was evaluated. Data were fed to the computer and analyzed using IBM SPSS software package version 20.0. At T0, Group II showed high PCO 2 gap (8.37 ± 1.36 mmHg) than Group I (7.55 ± 0.95 mmHg) with statistically significant difference ( P = 0.030). While at T6, Group II showed higher PCO 2 gap (9.48 ± 1.47 mmHg) with statistically significant difference ( P < 0.001) and higher mean lactate values (62.71 ± 23.66 mg/dl) with statistically significant difference ( P < 0.001) than Group I where PCO 2 gap and mean lactate values became much lower, 5.91 ± 1.12 mmHg and 33.61 ± 5.80 mg mg/dl, respectively. Group I showed higher lactate clearance (25.42 ± 6.79%) with statistically significant difference ( P < 0.001) than Group II (-69.40-15.46%). High PCO 2 gap >7.8 mmHg after 6 h from resuscitation of septic shock patients is associated with high mortality.

Shear-wave elastography (SWE) presents quantitative data that thought to represent intrinsic features of the target tissue. Factors affecting the metabolism of the breast parenchyma as well as age, menstrual cycle, hormone levels, pregnancy and lactation, pre-compression artifact during the examination could affect these elastic intrinsic features. Aim of our study is to determine variation of fibroadenoma elasticity during the menstrual cycle (MC) by means of real-time shear-wave elastography (SWE) and identify the optimal time for SWE evaluation. Thirty volunteers (aged 20-40 years) who had biopsy-proven fibroadenoma greater than 1cm in diameter, with regular menstrual cycle and without contraceptive medication underwent SWE (ShearWave on Aixplorer, France) once weekly during MC. Statistical data were processed by using the software Statistical Package for the Social Sciences (SPSS) 19.0. A repeated measures analysis of variance was used for each lesion where the repeated factor was the elastographic measurements (premenstrual, menstrual and postmenstrual). Pillai's trace test was used. Pairwise correlation was calculated using Bonferroni correction. Values of p<0.05 were considered statistically significant. The mean elasticity value of fibroadenomas in mid-cycle was 28.49 ± 12.92 kPa, with the highest value obtained in the third week corresponding to the premenstrual stage (32.98 ± 13.35 kPa) and the lowest value obtained in the first week corresponding to the postmenstrual stage (25.39 ± 10.21 kPa). Differences between the elasticity values of fibroadenomas in premenstrual and postmenstrual periods were statistically significant (p<0.001). There were no significant differences in lesion size between the different phases of the menstrual cycle (p>0.05). In this study, we found that there is significant difference between the elasticity values of fibroadenomas on premenstrual and postmenstrual period. We propose that one week after menstruation would be appropriate time to perform breast SWE. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

2012-01-01

Background and Aims: Shivering is distressing to the patient and discomforting to the attending anesthesiologist, with a varying degree of success. Various drugs and regimens have been employed to abolish the occurrence of shivering. The present study aims to explore the effectiveness of dexmedetomidine in suppressing the postanesthetic shivering in patients undergoing general anesthesia. Materials and Methods: The present study was carried out on 80 patients, in American Society of Anesthesiologists I and II, aged 22–59 years, who underwent general anesthesia for laparoscopic surgical procedures. Patients were allocated randomly into two groups: group N (n = 40) and group D (n = 40). Group D were administered 1 μg/kg of dexmedetomidine intravenously, while group N received similar volume of saline during peri-op period. Cardiorespiratory parameters were observed and recorded during the preop, intraop, and postop periods. Any incidence of postop shivering was observed and recorded as per 4 point scale. Side effects were also observed, recorded, and treated symptomatically. Statistical analysis was carried out using statistical package for social sciences (SPSS) version 15.0 for windows and employing ANOVA and chi-square test with post-hoc comparisons with Bonferroni's correction. Results: The two groups were comparable regarding demographic profile (P > 0.05). Incidence of shivering in group N was 42.5%, which was statistically highly significant (P = 0.014). Heart rate and mean arterial pressure also showed significant variation clinically and statistically in group D patients during the postop period (P = 0.008 and 0.012). A high incidence of sedation (P = 0.000) and dry mouth (P = 0.000) was observed in group D, whereas the incidence of nausea and vomiting was higher in group N (P = 0.011 and 0.034). Conclusions: Dexmedetomidine seems to possess antishivering properties and was found to reduce the occurrence of shivering in patients undergoing general anesthesia. PMID:22345953

Background: During fixed orthodontic therapy, adolescents tend to have higher chances of gingivitis and gingival enlargement (GE) compared to adults. A cross sectional study was undertaken to evaluate the above hypothesis, by assessing GE in patients of different age groups receiving fixed orthodontic therapy. Materials & Methods: Patients undergoing orthodontic treatment were selected by simple random sampling from the King Khalid University College of Dentistry out patient’s clinic of preventive dental sciences division to form the study group. Participant’s were divided into three age groups and GE was graded as 0, 1 and 2 as per the classification of the American Academy of Periodontology. Data were analyzed by using IBM SPSS version 16.0 (Statistical Package for Social Services, Chicago, IL, USA) and descriptive statistics were obtained. Differences in proportions were compared using the Chi-square test and the significance level was set at p ≤ 0.05. Results: 62.3% (n=33) were males and 37.7% (n=20) were females. Group 1 had 21 patients (39.7%); Group 2 had 24 patients (45.3%) and Group 3 had 8 patients (15.1%).The highest frequency (48%) of GE was observed among the Group 1 age group (10-19 years). Differences in frequency of GE according to age groups were found to be statistically significant (p=0.046).Differences in GE according to the frequency of practicing oral hygiene measures were statistically significant (p<0.001). Conclusion: Highest frequency of GE was observed among the adolescents. The patients who practiced oral hygiene measures more than three times daily did not have any GE. On the other hand, those who brushed and flossed only once daily had the highest percentage of grade 2 GE. How to cite the article: Eid HA, Assiri HA, Kandyala R, Togoo RA, Turakhia VS.

Nurse-physician communication has been shown to have a significant impact on the job satisfaction and retention of staff. In areas where it has been studied, communication failure between nurses and physicians was found to be one of the leading causes of preventable patient injuries, complications, death and medical malpractice claims. The objective of this study is to determine perception of nurses and physicians towards nurse-physician communication in patient care and associated factors in public hospitals of Jimma zone, southwest Ethiopia. Institution based cross-sectional survey was conducted from March 10 to April 16, 2014 among 341 nurses and 168 physicians working in public hospitals in Jimma zone. Data was collected using a pre-tested self-administered questionnaire; entered into EpiData version 3.1 and exported to Statistical Package for Social Sciences (SPSS) version 16.0 for analysis. Factor analysis was carried out. Descriptive statistics, independent sample t-test, linear regression and one way analysis of variance were used. Variables with P-value < 0.05 were considered as statistically significant. The response rate of the study was 91.55%. The mean perceived nurse-physician communication scores were 50.88±19.7% for perceived professional respect and satisfaction, and 48.52±19.7% for perceived openness and sharing of patient information on nurse-physician communication. Age, salary and organizational factors were statistically significant predictors for perceived respect and satisfaction. Whereas sex, working hospital, work attitude individual factors and organizational factors were significant predictors of perceived openness and sharing of patient information in nurse-physician communication during patient care. Perceived level of nurse-physician communication mean score was low among nurses than physicians and it is attention seeking gap. Hence, the finding of our study suggests the need for developing and implementing nurse-physician communication improvement strategies to solve communication mishaps in patient care.

Background: Lichen planus (LP) is a mucocutaneous disease that is relatively common among adult population. LP can present as skin and oral lesions. This study highlights the prevalence of oral, skin, and oral and skin lesions of LP. Aims: The aim of this study was to evaluate the prevalence of oral, skin, and oral and skin lesions of LP from a population of patients attending the Department of Oral Medicine and Radiodiagnosis, Pushpagiri College of Dental Sciences, Tiruvalla, Kerala, India. Materials and Methods: A cross-sectional study was designed to evaluate the prevalence of oral, skin, and oral and skin lesions of LP. This is a ongoing prospective study with results of 2 years being reported. LP was diagnosed on the basis of clinical presentation and histopathological analysis of mucosal and skin biopsy done for all patients suspected of having LP. Statistical analysis was carried out using SPSS (Statistical package for social sciences) software version 14. To test the statistical significance, chi-square test was used. Results: Out of 18,306 patients screened, 8,040 were males and 10,266 females. LP was seen in 118 cases (0.64%). Increased prevalence of LP was observed in middle age adults (40–60 years age group) with lowest age of 12 years and highest age of 65 years. No statistically significant differences were observed between the genders in skin LP group (P=0.12) and in oral and skin LP groups (P=0.06); however, a strong female predilection was seen in oral LP group (P=0.000036). The prevalence of cutaneous LP in oral LP patients was 0.06%. Conclusion: This study showed an increased prevalence of oral LP than skin LP, and oral and skin LP with a female predominance.

The generalized linear mixed-effects model (GLMM) is a popular paradigm to extend models for cross-sectional data to a longitudinal setting. When applied to modeling binary responses, different software packages and even different procedures within a package may give quite different results. In this report, we describe the statistical approaches that underlie these different procedures and discuss their strengths and weaknesses when applied to fit correlated binary responses. We then illustrate these considerations by applying these procedures implemented in some popular software packages to simulated and real study data. Our simulation results indicate a lack of reliability for most of the procedures considered, which carries significant implications for applying such popular software packages in practice.

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.

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.

The purpose of this descriptive study was to investigate attitudes women of towards cervical cancer prevention applications and early diagnosis, and whether or not their hopelessness levels had any influence. The present study was carried out in Isparta with a descriptive design. A sample of 251 individuals was recruited from January 2011 through May 2011 in the largest tea garden (restaurant- cafe). The data collection tool consisted of two parts: a "Questionnaire Form" identifying women; and the "Beck Hopelessness Scale". Data were analyzed using the Statistical Package for the Social Sciences (SPSS version 16.0 for Windows for the numerical and percentage distribution, average, standard deviation with the ANOVA and Mann-Whitney tests. Some 70.2 % of the woman indicated that they had not taken the Pap test. There was a significant relationship between the hopelessness level and women believing that they could protect themselves from getting cervical cancer (F=10.11 p=0.00). There was a significant relationship between hopelessness levels and believing whether or not early diagnosis tests are deterministic (F=8.781 p=0.00). Our study concluded that the hopelessness level of women had an effect on their thoughts about cervical cancer prevention and early diagnosis.

2012-01-01

Background 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. Methods 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. Results 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. Conclusions 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.

Women comprise 73 percent of all dentists in Bulgaria. Almost all of them started their careers as salaried, and now they are self-employed. The purpose of this study was to show how female dentists in Bulgaria met the challenges of the social and health reforms during the period of transition from totalitarian to democratic rule. A field sociological survey was carried out between October 1996 and June 1997, involving a sample of 842 dentists. The questionnaire was designed to give information on dental demography trends, pattern of participation and practice of female dentists, and their career development. The data were treated statistically using an SPSS package. Results show that for the period 1991-96 women dentists owned more than 50 percent of the newly opened private practices in Bulgaria. They were more interested in improving their qualifications and more successful in obtaining specialty status than male dentists. Dentists in Bulgaria by the late 1990 s, with no gender difference, tend to identify themselves as liberal practitioners within the pluralistic model of dental services delivery. The volume of services delivered and profile of women in professional practice and their social and professional mobility are highly competitive, despite the growing problems of maternity leave coverage and funding to re-enter the profession.

Agreeableness is associated with good mental health during pregnancy. Although different studies have indicated that agreeableness is related to adaptive coping, this relation has scarcely been studied in pregnant women. The aim of this study was to analyze the possible differences between high and low agreeableness in relation to coping strategies and psychiatric symptoms in pregnant women. We conducted a longitudinal prospective study between October 2009 and January 2013. Pregnant women (n = 285) were assessed in the first trimester of pregnancy, and 122 of them were assessed during the third. Data were collected using the Coping Strategies Questionnaire, the Symptom Check List 90-R, and the agreeableness subscale of the NEO-FFI. Using the SPSS 21 statistics package, binary logistic regression, two-way mixed analysis of variance, and multiple regression analyses and a Sobel test were conducted. Higher levels of agreeableness were associated with positive reappraisal and problem-solving, and lower levels of agreeableness were associated with overt emotional expression and negative self-focused coping. Women with low agreeableness had poorer mental health, especially in the first trimester. These findings should be taken into account to improve women's experiences during pregnancy. Nevertheless, given the scarcity of data, additional studies are needed.

To determine levels and correlates of caregiver burden among caregivers of children and adolescents with psychiatric morbidity. Over a period of four months, a total of 252 caregivers of children and adolescents with psychiatric morbidity were recruited. Data on socio-demographic factors, psychiatric morbidity among caregivers, and level of caregiver burden was collected using a researcher-designed socio-demographic questionnaire, Mini International Neuropsychiatric Interview, and Zarit burden interview, respectively. Data was analysed using statistical package for social sciences (SPSS) version 21. Females (n = 211, 83.7%) and mothers (n = 182, 72.2%) accounted for the majority of the study participants. The majority of caregivers reported moderate to severe caregiver burden; (n = 100, 39.7%). Being single or separated (B = -6.91, p = 0.001, β = -0.18) and presence of psychiatric morbidity (B = 7.44, p = 0.009, β = 0.22) in the caregiver significantly contributed to the high levels of caregiver burden. Caregivers of children and adolescents with psychiatric morbidity suffer high levels of caregiver burden. A multidisciplinary approach to management of children with psychiatric morbidity to address challenges faced by the caregivers may alleviate the burden; thereby improving clinical outcomes of children and adolescents with psychiatric morbidity.

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.

Gated communities are residential areas developed with restricted access with strictly controlled entrances and surrounded by a close perimeter of wall or fences. Developers, conscious of the need to fulfill the requirement of living in modern and sophisticated lifestyle and gated properties become the trend and mushroomed over the past decade. Nowadays, it is obvious that gated and guarded communities become almost a dominant feature of Malaysia housing development projects. The focus of this paper is to identify the factors contribute resident's decision to reside in gated and guarded community and to study social interaction among gated communities' residents. 150 questionnaires were distributed to the residents of selected gated and guarded community area in order to achieve the objectives and analyzed by using Statistical Package for Social Science (SPSS) and descriptive analysis. The result was tabulated and presented in charts and graphs for a clear and better understanding. The five main factors contribute to resident decision to reside in gated communities were identified and ranked; there are privacy, security, location, lifestyle and prestige. Besides, the residents are feeling neutral towards the facilities and services provided in their gated and guarded residential area. A comprehensive improvement towards the facilities and services is needed to reach higher satisfaction from the residents.

Hospice volunteers often encounter questions related to spirituality. It is unknown whether spiritual care receives a corresponding level of attention in their training. Our survey investigated the current practice of spiritual care training in Germany. An online survey sent to 1,332 hospice homecare services for adults in Germany was conducted during the summer of 2012. We employed the SPSS 21 software package for statistical evaluation. All training programs included self-reflection on personal spirituality as obligatory. The definitions of spirituality used in programs differ considerably. The task of defining training objectives is randomly delegated to a supervisor, a trainer, or to the governing organization. More than half the institutions work in conjunction with an external trainer. These external trainers frequently have professional backgrounds in pastoral care/theology and/or in hospice/palliative care. While spiritual care receives great attention, the specific tasks it entails are rarely discussed. The response rate for our study was 25.0% (n = 332). A need exists to develop training concepts that outline distinct contents, methods, and objectives. A prospective curriculum would have to provide assistance in the development of training programs. Moreover, it would need to be adaptable to the various concepts of spiritual care employed by the respective institutions and their hospice volunteers.

Most consumers are able to recognize allergenic foods. However, the frequency of checking such foods is reportedly low, resulting in higher prevalence of food-related allergic reactions in Korea compared to other countries. Thus, this study was performed to investigate the overall perception of allergenic food labeling and its practice level in food manufacturing company employees. The survey was administered to food safety employees and food development teams at food companies located in metropolitan areas. A total of 399 (93.8%) valid samples were used in the final analysis. Statistical analyses, including Frequency Analysis, t-test, Anova, PCA (Principal Component Analysis), and Pearson Correlation Analysis using SPSS ver. 21.0, were performed. The correct answer rate in the analysis of allergy-related knowledge level ranged from 15.0% to 89.7%. Analysis of differences in allergy-related perception by knowledge level showed significant differences in introduction of a food recall system, strengthening of relevant laws and regulations, content labeling, description of substitutional food, and differentiated package by age. It can be concluded that labeling of allergenic foods should be made easier and more convenient for checking by employees, developers, and consumers, and it is necessary to provide contents through the development of publicity, guidelines, or APP along with labeling.

Premature loss of primary molars due to dental caries and their complications has been associated with space loss and eruptive difficulties, especially when the loss occurs early. The aim of our study was to determine the impact of premature loss of temporary upper molars upon the longitudinal axis of the first and second upper permanent molar. The study group included 64 patients 6-9 years old with premature loss of primary molars and a control group of 48 patients with intact temporary teeth. It was evaluated the angle between longitudinal axis of first and second upper permanent molars and occlusal plane. The sofware used is Easy Dent 4 Viewer®.The data were analyzed by using the Statistical Package for the Social Sciences (version 20.0; SPSS, Chicago, III). It was observed that premature loss of upper second deciduous molars modifies greater the vertical axis of the permanent molars than the premature loss of first upper primary molar. First upper primary molar loss cause an acceleration eruption of first premolar, which will produce a distal inclintion of the both permanent molars. The use of space maintainers after premature loss of the second upper temporary molar is a last solution in preventing tridimensional lesions in the dental arch and occlusion.

Actuaries, demographers and other professionals have always been aware of the critical importance of mortality forecasting due to declining trend of mortality and continuous increases in life expectancy. Heligman-Pollard model was introduced in 1980 and has been widely used by researchers in modelling and forecasting future mortality. This paper aims to estimate an eight-parameter model based on Heligman and Pollard's law of mortality. Since the model involves nonlinear equations that are explicitly difficult to solve, the Matrix Laboratory Version 7.0 (MATLAB 7.0) software will be used in order to estimate the parameters. Statistical Package for the Social Sciences (SPSS) will be applied to forecast all the parameters according to Autoregressive Integrated Moving Average (ARIMA). The empirical data sets of Malaysian population for period of 1981 to 2015 for both genders will be considered, which the period of 1981 to 2010 will be used as "training set" and the period of 2011 to 2015 as "testing set". In order to investigate the accuracy of the estimation, the forecast results will be compared against actual data of mortality rates. The result shows that Heligman-Pollard model fit well for male population at all ages while the model seems to underestimate the mortality rates for female population at the older ages.

Farming as a livelihood activity in the Bosomtwe District is threatened by climate change. This paper ascertained the alternative livelihood options of smallholder farmers against climate variability and change in the Bosomtwe District. Using a cross-sectional survey, 152 smallholder farmers were sampled from 12 communities using a multistage sampling procedure. The quantitative data collected were subjected to binary logistic regression analysis, contingency tables, frequencies, and Nagelkerke tests of association, embedded in the statistical package for social sciences (SPSS) v.17. The results indicate that farmers are resorting to alternative livelihood activities that are less capital intensive and require less skill in order to secure income and household food supply. Significant determinants of farmers' alternative livelihood are age, household size, and household food supply, which were significant at p < .030, p < .019, and p < .012, respectively. At a 95% confidence interval (CI), these variables had lower to upper CIs for each of the EXP (B), respectively, at CI = 1.134–12.524, CI = 1.359–30.224, and CI = 1.781–104.561, respectively. The paper recommends that government institutes policies that will create opportunities and draw on various local/grassroots opportunities and resources to expand farmers' asset base for sustainable livelihood strategies.

Traditional methods of teaching entrepreneurship in universities involves more theoretical approaches which are less effective in motivating considerations for an entrepreneurship career. This owes to the fact that such techniques essentially make students develop a dormant attitude rather than active participation. Expert views suggest that experiential entrepreneurship teaching methods in universities which involve practical activities and active participation can be considered salient to students' development of entrepreneurial interest an business startup potentials. This present study presents data on the extent to which experiential teaching methods in entrepreneurship adopted by Nigerian universities stimulate students' entrepreneurial interest and business startups. Data have been gathered following a descriptive cross-sectional quantitative survey conducted among university students ( N = 600) of four selected institutions in Nigeria offering a degree programme in entrepreneurship. Hierarchical Multiple Regression Analysis was used in confirming the hypothesis proposed in the study using the Statistical Package for Social Sciences (SPSS) version 22.The findings from the analysis showed that the adoption of experiential practical activities considered as best practices in entrepreneurship teaching in Nigerian universities can stimulate students' interest and drive for engaging in business start-up activities even as undergraduates. The field data set is made extensively available to allow for critical investigation.

To correlate emotional reactions to tooth loss with denture satisfaction attributes in elderly complete denture wearers. Total tooth loss is a serious life event, and poor oral health has an impact on daily life. Edentulism treated by rehabilitation with dentures can have a positive effect on patients' self-image and social behaviour. A group of 80 edentulous subjects undergoing routine prosthetic care in a Greek Department of Prosthetic Dentistry were interviewed using two structured questionnaires. The first questionnaire explored reactions to tooth loss, whereas the second measured their subjective experience of complete dentures. The responses to both questionnaires were compared using the statistical package SPSS v.17. The results showed significant correlation between aspects of tooth loss experience and complete denture satisfaction. Despite the fact that a substantial proportion of patients were satisfied with their complete dentures, some patients experienced increased social and psychological problems related to their edentulousness and the wearing of complete dentures. The aesthetic and functional aspects of complete dentures affected both patients' social behaviour and self-confidence. Total tooth loss was not only reflected in patient's social behaviour and self-image, but it had a complex and multifaceted impact on satisfaction from complete dentures. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Viral infections and chronic diseases have been associated with psychiatric disorders. Among these, increased depression has been reported in HTLV-1 patients. However, no studies on the prevalence of other mental disturbances have been carried out in these patients. Salvador is the city with the highest rate of infection with HTLV-1 in Brazil and it is estimated that approximately 40,000 inhabitants are infected. In our cross sectional study, we examined the frequency of mental disturbances in 50 HTLV-1 seropositive patients followed at the Centro Integrativo e Multidisciplinar de HTLV e Hepatites Virais (CHTLV) of the Escola Bahiana de Medicina e Saude Pública (EBMSP) in Salvador from January to November 2007. We used a questionnaire to collect clinical-epidemiologic data and the Mini International Neuropsychiatric Interview Brazilian Version 5.0.0 (M.I.N.I.) to evaluate the psychiatric disorders. The Statistical Package for Social Sciences (SPSS) was used for the analyses. Twenty-one (42%) HTLV-1 patients had a psychiatric co-morbidity; 17(34%) had mood disorders, 11 (22%) were anxious and one (2%) was an alcoholic. We found a high frequency of mental disturbances among HTLV-1 infected individuals, suggesting a possible association of this infection with psychiatric diseases.

ABSTRACT Objective: to analyse the effects of relaxation as a nursing intervention on the depression levels of hospitalised women with high-risk pregnancies. Methods: a randomised clinical trial realised in a reference centre for high-risk pregnancies. The sample consisted of 50 women with high-risk pregnancies (25 in the control group and 25 in the intervention group). The Benson relaxation technique was applied to the intervention group for five days. Control variables were collected using a predesigned form, and the signs and symptoms of depression were evaluated using the Edinburgh Postnatal Depression Scale (EPDS). The Statistical Package for Social Sciences (SPSS), version 20.0, was used with a significance level of 5%. The Wilcoxon and paired t-tests were used to evaluate depression levels between two timepoints. Using categorical data, the McNemar test was used to analyse differences in depression severity before and after the intervention. Results: depression levels decreased in the intervention group five days after the relaxation technique was applied (4.5 ± 3, p<0.05) compared with the levels at the first timepoint (10.3±5.9). Conclusion: as a nursing intervention, relaxation was effective in decreasing the symptoms of depression in hospitalised women with high-risk pregnancies. PMID:27627126

Accidents cause major damage for both workers and enterprises in the mining industry. To reduce the number of occupational accidents, these incidents should be properly registered and carefully analysed. This study efficiently examines the Aegean Lignite Enterprise (ELI) of Turkish Coal Enterprises (TKI) in Soma between 2006 and 2011, and opencast coal mine occupational accident records were used for statistical analyses. A total of 231 occupational accidents were analysed for this study. The accident records were categorized into seven groups: area, reason, occupation, part of body, age, shift hour and lost days. The SPSS package program was used in this study for logistic regression analyses, which predicted the probability of accidents resulting in greater or less than 3 lost workdays for non-fatal injuries. Social facilities-area of surface installations, workshops and opencast mining areas are the areas with the highest probability for accidents with greater than 3 lost workdays for non-fatal injuries, while the reasons with the highest probability for these types of accidents are transporting and manual handling. Additionally, the model was tested for such reported accidents that occurred in 2012 for the ELI in Soma and estimated the probability of exposure to accidents with lost workdays correctly by 70%.

The present study’s objective was to determine the mechanisms for enhancing the utility of action checklists applied in participatory approach programs for workplace improvements, to identify the benefits of building consensus and to compare their applicability in Asian countries to find the most appropriate configuration for action checklists. Data were collected from eight trainees and 43 trainers with experience in Participatory Action-Oriented Training. Statistical analysis was performed in SPSS using the package PASW, version 19.0. The difference in the mean score for the degree of the utility of action checklists between countries was analyzed using ANOVA methods. Factor analysis was performed to validate the action checklists’ utility. Pearson Correlation Coefficients were then calculated to determine the direction and strength of the relationship between these factors. Using responses obtained from trainees’ in-depth interviews, we identified 33 key statements that were then classified into 11 thematic clusters. Five factors were extracted, namely “ease of application”, “practical solutions”, “group interaction”, “multifaceted perspective” and “active involvement”. The action checklist was useful for facilitating a participatory process among trainees and trainers for improving working conditions. Action checklists showed similar patterns of utility in various Asian countries; particularly when adjusted to local conditions. PMID:25224334

The level of IL-1 beta mRNA and IL-6 mRNA increased significantly after treatment with P.e-LPS at more than 5 microg/mL (P<0.01)and for more than 1 hour (P<0.01), which indicated that P.e-LPS induced osteoblasts to express IL-1 beta mRNA and IL-6 mRNA in dose and time dependent manners. P.e-LPS may promote bone resorption in lesions of chronical apical periodontitis by inducing IL-1 beta mRNA and IL-6 mRNA expression in osteoblasts.

Anaemia is highly prevalent among pregnant women and iron deficiency is the most important cause. Like many other countries, India has policies to give pregnant women iron supplements. Non-compliance is one important challenging factor in combating anaemia. To estimate the compliance for IFA tablets among pregnant women and to study the social factors influencing it. This study included 190 pregnant women seeking ante-natal care in tertiary health centres in the Mangalore city in south India. After Institutional Ethics Committee (IEC) approval, data was collected by personal interview. Missing >2 doses consecutively was considered non-compliance. The data was analyzed using SPSS (Statistical Package for Social Sciences) version 11.5. The mean age of the study population was 25.8 years (SD: 4.1). Most of the subjects consumed mixed diet and 72.1% belonged to lower socioeconomic status. Overall, compliance with IFA tablets was 64.7%. Compliance increased with the increase in age, birth order and single daily dose. Forgetfulness and both perceived as well as experienced side effects of IFA therapy were the important factors for non-compliance. There was a moderate level of compliance towards IFA tablets with key social and demographic factors playing an important role.

The objective of this study is to identify the need for basic first aid knowledge and skills among adolescents. A cross-sectional study using multistage sampling was conducted among 375 secondary school students in Kuantan, Pahang, Malaysia. The survey was adapted from a Hong Kong Red Cross survey. A back to back translation of this instrument was carried out by two bilingual medical experts with Cronbach's alpha 0.8. The data were analyzed using SPSS (Statistical Package for the Social Sciences) in terms of descriptive analysis, and an independent t-test and chi-square test were carried out. There were 149 respondents from the lower form (grade level) and 226 respondents from the upper form. The majority of respondents (81.6%) were Malay. An independent t-test revealed a significant association between knowledge and attitude, as students who scored higher on first aid questions showed a more positive attitude towards first aid (1.475%). There were also significant associations between race and experience learning first aid. Adolescents receive minimal first aid education. Thus, there is an urgent need to educate adolescents more in first aid to promote a safer community and to prevent any further injuries. Copyright © 2018 Elsevier España, S.L.U. All rights reserved.

Kawasaki disease (KD) is now the commonest cause of acquired heart disease in children in developed countries. KD occurs all over the world, including developing countries. The present study steps out to explore our hypothesis, driven by clinical observation over the last 18 years, whether children with KD in North India are of a higher socioeconomic status than children with other rheumatologic diseases. One hundred consecutive children with KD, registered in Pediatric Rheumatology Clinic before January 2011, were enrolled as cases. Children with other rheumatologic diseases were taken as controls. Assessment of socioeconomic status was done by administering the Aggarwal scale. Data were collected through interview. Statistical analysis was done using SPSS package version 16. On univariate analysis, male sex, higher educational status of parents, urban residence, immunization status being complete, and higher scores on Aggarwal scale were found to be significantly associated with KD. On multivariate analysis, only male sex and urban residence were found to be significantly associated with KD (p < 0.001). Families of children with KD tend to have a better sociodemographic profile when compared with other pediatric rheumatologic disorders in North India. These results, however, need to be replicated in a multicentric study for any firm conclusions to be drawn.

The objective of this study was to determine the prevalence of waterpipe (shisha) smoking and associated factors among Malaysian university students. A total of 200 university students from Management and Science University participated in this study. The survey was conducted by simple random sampling by randomly distributing self-administered questionnaires to the library, cafeterias and classes. The protocol of this study was approved by the ethics committee of Management and Science University. Consent forms were obtained from the students before they answered the questionnaire. Statistical analyses were performed using the Statistical Package for Social Science (SPSS) version 13. with the Student's t-test for comparison of the mean practice and backward multiple linear regression for multivariate analysis. The majority of the subjects were male, single, Malay and from urban areas (61.5%, 94.5%, 66%, 76.5%; respectively). In this study 30% of the study participants were shisha smokers. Regarding knowledge about shisha smoking, the majority (48.5%) mentioned that shisha is less harmful than cigarettes and 55% reported that shisha is less addictive. Univariate analysis showed that age, race, sex and income significantly influenced the practice of smoking shisha among university students (p=0.019, p=0.002, p=0.001, p=0.018; respectively). For multivariate analysis, income and gender demonstrated significant influence (both p=0.001). There was a high prevalence of shisha smoking among Malaysian university students and knowledge about the dangers is low. Income and gender significantly influenced the practice of smoking shisha in our population. Banning of smoking including shisha smoking in public places is strongly recommended.

To detect the anticandidal activity of nine toothpastes containing sodium fluoride, sodium monofluorophosphate and herbal extracts as an active ingredients against 45 oral and non oral Candida albicans (C. albicans) isolates. The antifungal activity of these toothpaste formulations was determined using a standard agar well diffusion method. Statistical analysis was performed using a statistical package, SPSS windows version 15, by applying mean values using one-way ANOVA with post-hoc least square differences (LSD) method. A P value of less than 0.05 was considered significant. All toothpastes studied in our experiments were effective in inhibiting the growth of all C. albicans isolates. The highest anticandidal activity was obtained from toothpaste that containing both herbal extracts and sodium fluoride as active ingredients, while the lowest activity was obtained from toothpaste containing sodium monofluorophosphate as an active ingredient. Antifungal activity of Parodontax toothpaste showed a significant difference (P< 0.001) against C. albicans isolates compared to toothpastes containing sodium fluoride or herbal products. In the present study, it has been demonstrated that toothpaste containing both herbal extracts and sodium fluoride as active ingredients are more effective in control of C. albicans, while toothpaste that containing monofluorophosphate as an active ingredient is less effective against C. albicans. Some herbal toothpaste formulations studied in our experiments, appear to be equally effective as the fluoride dental formulations and it can be used as an alternative to conventional formulations for individuals who have an interest in naturally-based products. Our results may provide invaluable information for dental professionals.

Context: Elder abuse and social neglect are unrecognized problem. Many forms of elder abuse exist including physical, psychological, financial, sexual and social neglect. Social neglect is experienced by elderly through loss of friends and family members. Aim: Comparison of perceived abuse and social neglect among elderly residing in selected rural and urban areas. Settings and Design: Study setting was a rural area Pohir and urban area Jamalpur of district Ludhiana. Subjects and Methods: A sample of 200 subjects (100 subjects each from rural and urban area respectively) of age 60 years and above was drawn by cluster sampling technique and interview method was used to collect data by using Likert scale. Statistical Analysis: Descriptive and inferential statistics were carried out with SPSS package. Results: Results of the present study revealed that perceived physical abuse (25%) was higher among elderly residing in rural and it was found significantly higher among female elderly who were illiterate, widow/widower and partially dependent on caregiver whereas perceived psychological abuse (71%), financial abuse (37%) and social neglect (74%) were higher among elderly residing in urban. A significant association was found between psychological abuse and educational status, which inferred that as the level of education increases perception of psychological abuse also increases. The perceived financial abuse was significantly higher among male elderly who were financially independent. Conclusion: It was concluded that social neglect was most common, followed by psychological abuse and financial abuse among elderly residing in urban whereas physical abuse was more prevalent among elderly residing in rural.

Findings of most studies indicate that the only way to control diabetes and prevent its debilitating effects is through the continuous performance of self-care behaviors. Physical activity is a non-pharmacological method of diabetes treatment and because of its positive effects on diabetic patients, it is being increasingly considered by researchers and practitioners. This study aimed at determining factors influencing physical activity among diabetic women in Iran, using the extended theory of reasoned action in Iran. A sample of 352 women with type 2 diabetes, referring to a Diabetes Clinic in Khoy, Iran, participated in the study. Appropriate instruments were designed to measure the desired variables (knowledge of diabetes, personal beliefs, subjective norms, perceived self-efficacy, behavioral intention and physical activity behavior). The reliability and validity of the instruments were examined and approved. Statistical analyses of the study were conducted by inferential statistical techniques (independent t-test, correlations and regressions) using the SPSS package. The findings of this investigation indicated that among the constructs of the model, self efficacy was the strongest predictor of intentions among women with type 2 diabetes and both directly and indirectly affected physical activity. In addition to self efficacy, diabetic patients' physical activity also was influenced by other variables of the model and sociodemographic factors. Our findings suggest that the high ability of the theory of reasoned action extended by self-efficacy in forecasting and explaining physical activity can be a base for educational intervention. Educational interventions based on the proposed model are necessary for improving diabetics' physical activity behavior and controlling disease.

Background/Aim: Significant change has been happening in the introduction of technology in medical teaching all over the world. We aim to determine if the undergraduate medical students and teachers are open to incorporating changes in the current medical curriculum or if there is a need for the same in the Republic of Ireland. Materials and Methods: A cross-sectional study involving 202 participants of whom 152 were medical students and 50 medical professionals (teachers and hospital doctors) were carried out involving three different medical universities namely; University College Cork (UCC), University College Dublin (UCD), and National University of Ireland in Galway (NUIG). Participants were requested to answer a series of 15 questions designed incorporating various fields of technology necessary for the study. The data was collected and analyzed using Statistical Package for Social Sciences (SPSS) software to determine statistical significance. Results: The participants overall had a positive attitude toward the utility of modern technology and web-based applications in current medical curriculum. Ninety-one percent of the participants preferred the introduction of modern technology into medical education and 7% were against the idea and a further 2% of them remained undecided. Conclusion: There seems to be a “technology gap” in the current undergraduate medical curriculum in Ireland. A large-scale study involving more participants from all the medical schools in Ireland is recommended. We believe, changes can be brought into the current medical teaching and learning to make the process more fruitful and successful. PMID:25097432

PubMed Central

2011-01-01

Background Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health. Methods The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs). Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13) was used for the statistical analysis. P-values < 0.05 were considered significant. Results Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%), vitamin A (92.4%) and vitamin C (85.1%) in both genders. Intake variations were found between different regions, which may reflect cultural habits. Conclusion These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.

Malnutrition represents an important issue in older adults; unfortunately, there is lack of data concerning this topic in Lebanon. This paper aims to provide a description of nutritional status and its correlates in older adults living in long stay institutions situated in Beirut. This cross-sectional study was conducted in three long stay institutions in Beirut in 2012. The study population was composed of people aged 65 years and above, having a score of Folstein Mini Mental State Examination (MMSE) greater than 14 and without renal failure requiring dialysis. Subjects meeting inclusion criteria filled out a questionnaire consisting of nutritional status scale (Mini Nutritional Assessment: MNA) and several other parts (demographic, self-assessment of the state health, smoking and alcohol, physical dependence, quality of life, frailty, depression, social isolation and loneliness). Data were entered and analyzed using the statistical software SPSS (Statistical Package for Social Sciences), version 17.0 (Chicago, IL, USA). Among 111 older adults (55 men and 56 women), 14 (12.6%) were malnourished, 54 (48.7%) were at risk of malnutrition and 43 (38.7%) had an adequate nutritional status. Multivariate analysis showed that physical exercise, depression, frailty and cognitive function were independent correlates of nutritional status of older adults. This model explained 42.2% (adjusted R2 = 0.422) of the older adults nutritional status variability. We found a moderate percentage of malnutrition in older adults living in long stay institutions situated in Beirut, and the correlates of malnutrition in older adults were low physical exercise, depression, frailty and low cognitive function.

The agricultural industry is the largest economic sector in Palestine and is characterized by extensive and unregulated use of pesticides. The objective of this study was to analyze phone calls received by the Poison Control and Drug Information Center (PCDIC) in Palestine regarding pesticide poisoning. All phone calls regarding pesticide poisoning received by the PCDIC from 2006 to 2010 were descriptively analyzed. Statistical Package for Social Sciences (SPSS version 16) was used in statistical analysis and to create figures. A total of 290 calls regarding pesticide poisoning were received during the study period. Most calls (83.8%) were made by physicians. The average age of reported cases was 19.6 ± 15 years. Pesticide poisoning occurred mostly in males (56.9%). Pesticide poisoning was most common (75, 25.9%) in the age category of 20-29.9 years. The majority (51.7%) of the cases were deliberate self-harm while the remaining was accidental exposure. The majority of phone calls (250, 86.2%) described oral exposure to pesticides. Approximately one third (32.9%) of the cases had symptoms consistent with organophosphate poisoning. Gastric lavage (31.7%) was the major decontamination method used, while charcoal was only utilized in 1.4% of the cases. Follow up was performed in 45.5% of the cases, two patients died after hospital admission while the remaining had positive outcome. Pesticide poisoning is a major health problem in Palestine, and the PCDIC has a clear mission to help in recommending therapy and gathering information.

Background: The close sustained contact of family physician with their patients and local community makes preventive care an integral part of their routine work. Most cardiovascular diseases (CVD) can be prevented by addressing their risk factors. There are several guidelines that recommend different CV risk assessment tools to support CV prevention strategies. Aim: This study aimed to assess awareness and attitude of global CV risk assessment and use of their tools by family physicians; aiming to improve CV prevention service. Methods: The current study is a cross-sectional descriptive analytic. Sixty-five family physicians were asked to respond to, validated anonymous questionnaire to collect data about characteristics of family physicians, their awareness, attitude, current use, barriers, and recommendations of global CV risk assessment. Statistical Package for Social Sciences (SPSS) version 18 was used for data entry and analysis. Results: Awareness of guidelines of global CV risk assessment was relatively higher regarding the American guidelines (30.8%) than that recommended by World Health Organization (WHO) for Egypt (20.2%). 50.8% of participants had favorable attitude. There was statistical significant relationship between attitude scores and physician characteristics; age (P = 0.003), qualification (P = 0.001) and number of patients seen per week (P = 0.009). Routine use of global CV risk assessment tools was reported only (23%) by family physicians. Conclusion: Relative higher attitude scores than use of global CV risk assessment tools in practice. The most frequent barriers were related to lack of resources and shortage in training/skills and the raised suggestions were towards training. PMID:26664843

There is little information available in the literature concerning the contribution of dementia in injury deaths in elderly people (≥60 years). This study was intended to investigate the extent of dementia-related pathologies in the brains of elderly people who died in traffic accidents or by suicide and to compare our findings with age- and sex-matched natural deaths in an elderly population. Autopsy-derived human brain samples from nine injury death victims (5 suicide and 4 traffic accidents) and nine age- and sex-matched natural death victims were screened for neurodegenerative and cerebrovascular pathologies using histopathological and immunohistochemical techniques. For the analysis, Statistical Package for the Social Sciences (SPSS) version 16.0 was used. There was a greater likelihood for Alzheimer's disease (AD)-related changes in the elders who succumbed to traffic accidents (1 out of 4) compared to age- and sex-matched suicides (0 out of 5) or natural deaths (0 out of 9) as assessed by the National Institute on Aging - Alzheimer's Association guidelines. Actual burden of both neurofibrillary tangles (NFTs) and (SPs) was comparatively higher in the brains of traffic accidents, and the mean NFT counts were significantly higher in the region of entorhinal cortex ( P < 0.05). However, associations obtained for other dementia-related pathologies were not statistically important. Our findings suggest that early Alzheimer stages may be a contributing factor to injury deaths caused by traffic accidents in elderly people whereas suicidal brain neuropathologies resembled natural deaths.

Background: Prerequisite for management of a chronic disease involves knowledge about its complications and their prevention. Hemophilia in adolescents influences all the aspects of their lives and thier performance. Objectives: The present study aimed to determine the performance of Iranian hemophilic adolescents in prevention of disease complications. Patients and Methods: In this descriptive-analytical study, 108 adolescents with hemophilia were selected through convenience sampling. Their performance in preventing the complications of hemophilia was evaluated by sending a semi-structured questionnaire to their addresses throughout Iran. Then, the data was analysed using the Statistical Package for Social Sciences (SPSS) software (v. 13) and descriptive and interferential statistics were used. Results: Overall, 32.1% of the participants controlled bleeding during the 1st hour. Inaccessibility of coagulation products was mainly responsible for inhibiting timely and proper bleeding control. In order to relieve bleeding associated pain, only 39.0% of the adolescents used analgesics. On the other hand, 19.8% of the subjects used nonpharmacological methods to relieve pain. The majority of the adolescents did not participate in sport activities (65.4%) others allocated less than 5 hours a week to physical activities (70.5%). In addition, the participants did not have favorable dietary patterns, exercise habits, and dental care. The results showed a significant relationship between the adolescents’ preventive practice with coagulation disorders and utilization of pharmacological pain relief methods. Also, significant relationships were found between severity of the disease; participating in physical activities, number of hours of physical activities; and disease complications. Conclusions: Iranian adolescents did not exhibit favorable practices towards complication prevention. PMID:26600702

2017-01-01

Background: Eosin is most widely used synthetic dye belonging to the xanthene group. These dyes are efficient but are hazardous to human and animal health. With the increasing awareness of a green earth, it is advisable to use more of eco-friendly and biodegradable material which can be effectively achieved by the use of natural dyes obtained from plants and other natural sources. Turmeric, available as Curcuma longa (domestic), has long been in use in the subcontinent as a spice and flavoring agent in most food preparations. Its health benefit as a natural antibiotic and anti-inflammatory has been successfully established by several researchers. The intense yellow color imparted by turmeric inspired us to explore its efficacy as a potential alternative for eosin in routine histopathological procedures. Aim: The aim of this was to explore the efficacy of turmeric extract as a stand-alone counterstain for hematoxylin and its comparative assessment with routine H and E staining. Materials and Methods: The rhizomes of C. longa were cut into small pieces, dried and milled. This powder was dissolved into alcohol and centrifuged using a centrifugal machine. The supernatant was then collected with the help of micropipette. This supernatant was used as a counterstain for hematoxylin. Results: The data were analyzed using Mann–Whitney U test with Statistical Package for the Social Sciences version 15.0 (SPSS Inc.,). The P value obtained was statistically insignificant (P > 0.05). Conclusion: Although eosin is the most efficient counterstain for hematoxylin, turmeric can also be used as an alternative for eosin. PMID:29391705

This in vitro study aimed to evaluate and compare marginal fit of three-unit fixed dental prostheses (FDPs) fabricated using a newly developed direct metal laser sintering (DMLS) system with that of three-unit FDPs by a conventional lost wax technique (LW) method. Ten cobalt-chromium alloy three-unit FDPs using DMLS system and another ten nickel-chromium alloy FDPs using LW method were fabricated. Marginal fit was examined using a light-body silicone. After setting, the silicon film was cut into four parts and the thickness of silicon layer was measured at 160× magnification using a digital microscope to measure absolute marginal discrepancy (AMD), marginal gap (MG) and internal gap (IG). A repeated measure ANOVA for statistical analysis was performed using the SPSS statistical package version 12.0 (α=0.05). The mean values of AMD, MG, and IG were significantly larger in the DMLS group than in the LW group (p<0.001). Means of AMD, MG and IG in the first molars were 83.3, 80.0, and 82.0μm in the LW group; and 128.0, 112.0, and 159.5μm in the DMLS group, respectively. No significant difference between measurements for premolars and molars was found (p>0.05). The marginal fit of the DMLS system appeared significantly inferior compared to that of the conventional LW method and slightly larger than the acceptable range.

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.

Most of the medicine users remain unaware about the disposal of unused or expired medicines. The aim of this study was to know the disposal practices of unused and expired medicines among the general public in Kabul. This was a descriptive, cross-sectional survey, conducted through face-to-face interviews using prevalidated structured questionnaire. Returned questionnaires were double-checked for accuracy. Statistical Package for Social Science (SPSS) version 23 was used for statistical analysis. Total of 301 valid questionnaires were returned with a response rate of 100% in which 73.4% men and 26.6% women participated. More than half of the respondents were university graduates. Interestingly, 83.4% of the interviewees purchased medicines on the prescription of which 47.2% were university graduates, while 14.6% purchased medicine over the counter. Among the respondents, 46.5/100 purchased antibiotics and the remaining purchased NSAIDs, anti-hypertensive and anti-diabetic medicines. Significantly, 97/100 checked the expiry date of medicine before buying. Majority (95.3%) of the respondents' stored medicines at home. 77.7% of the respondents discarded the expired medicines in household trash. Majority of respondents held government responsible for creation of awareness for proper medicine disposal. Almost entire sample (98%) felt that improper disposal of unused and expired medicines can affect the environment and health. Gaps exist in practices, therefore robust, safe and cost-effective pharmaceutical waste management program supported with media campaign is needed. Healthcare practitioners and community pharmacists should offer training to educate customers on standard medicine disposal practices.

To determine the progression of pigment dispersion syndrome (PDS) into pigmentary glaucoma (PG) in a population at the Central Military Hospital in Bogotá, Colombia. A retrospective study was conducted, based on a review of medical records of patients with PDS evaluated in the Glaucoma Clinic. Data were collected in a database in excel and subsequently analyzed with the software Statistical Package for the Social Sciences (SPSS), performing Chi-square test analysis and Spearman's rho test. Forty-eight eyes of 24 patients were included. Forty-two percent were women and 58% were men. Pigmentation of the trabecular meshwork was the most frequent clinical sign (100%), followed by Krukenberg's spindle (91.7%), the least frequent were the iris concavity and iris heterochromia (4.2%), the average of the spherical equivalent was of - 1.33 (SD 2.07). The rate of conversion of PDS to PG was 37.5%, after an average follow-up of 50.7 months. Having an intraocular pressure (IOP) greater than 21 mm Hg was statistically the only significant risk factor for conversion. We found several differences in frequency and clinical signs in these patients in contrast to previous data, probably due to different racial characteristics. The rate of progression is similar to previous reports despite of heterogeneity of these. Having IOP > 21 mm Hg was the only risk factor associated with progression in this sample.

The aim of this study was to compare the effectiveness of nano-hydroxyapatite (nano-HAP) paste and fluoride varnish in remineralizing initial enamel lesion in young permanent teeth and their ability to resist secondary caries under dynamic pH cycling quantitatively and qualitatively. Initial caries-like lesions were artificially developed on 45 specimens. Specimens were divided into three groups: (1) Control (without treatment), (2) fluoride varnish (3M ESPE), and (3) nano-HAP paste (Desensibilize Nano P). The nano-HAP paste was applied twice separated by one pH cycle, and the varnish was applied only once followed by 7 days of pH cycling. All specimens were examined using DIAGNOdent® pen (KaVo, Germany), and a representative specimen was randomly selected from each group for qualitative evaluation using scanning electron microscope (SEM) at four stages: Baseline, after lesion formation, immediately after remineralization, and after pH cycling. Data were statistically analyzed with Statistical Package for the Social Sciences (SPSS), version 20. The degree of demineralization was significantly elevated in control group; however, no significant difference was found between fluoride varnish group and nano-HAP paste group (p < 0.001). Nano-HAP paste showed promising long-term protective effect in terms of surface depositions and maintaining a smooth surface compared with fluoride varnish. Based on the findings of this study, nano-HAP paste might be recommended as alternative remineralizing agent with lower fluoride concentration than fluoride varnish that could be beneficial for children, pregnant females, and those who are at high risk of dental fluorosis.

The study compared the effects of isometric quadriceps exercise and proprioceptive exercise on pain, joint stiffness and physical difficulties of patients with knee osteoarthritis. Forty-five patients with history of knee osteoarthritis were randomly allocated into two groups; A with 23 subjects and B with 22 subjects. All subjects received infrared radiation for 20 minutes and kneading massage with methyl salicylate ointment. Group A underwent proprioceptive exercises while Group B had isometric quadriceps exercise. Each exercise session lasted for 10 minutes according to standard protocol, twice in a week for six weeks. Pre-treatment, 3rd week and 6th week pain intensity, joint stiffness and physical difficulties were assessed using Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Statistical package for social sciences (SPSS) version 17 was used to analyse the data while descriptive and inferential statistics were used to summarise the result. Proprioceptive exercises reduced pain intensity significantly (F = 4.76; p = 0.00) at 6th week with effect size of 2.79, and physical difficulty (F = 3.69; p < 0.04) with effect size of 7.53 better than isometric exercises. There was a significant reduction in the pain intensity (F = 12.08; p < 0.001), and physical difficulties (F = 3.69, p = 0.04) in pre-treatment, 3rd week and 6th week in both Group A and B. Both exercises are effective but proprioceptive exercises may be more effective in the management of patients with knee osteoarthritis (KOA) than isometric exercises.

Despite international findings that farmers have better health outcomes than other occupation groups, Irish farmers are found to be a high-risk group for cardiovascular disease (CVD). Early detection of CVD through preventive health measurements, such as screening of high-risk groups, can contribute to a reduction of CVD cases. Farmers, however, represent a "challenging" group in terms of engaging in preventive health behaviors. This study examined the prevalence of cardiovascular risk factors among male Irish livestock farmers who participated in heart screening as part of a workplace health intervention. In this cross-sectional study, data were collected from a convenience sample (N = 310) of farmers. Consent included permission to analyze the heart screening results and to participate in two follow-up questionnaires by phone at Week 1 (n = 224) and Week 12 (n = 172). All data were entered onto the Statistical Package for the Social Sciences (SPSS version 22) and both descriptive and inferential statistics were compiled. Almost one in two (46%; n = 140) farmers had high blood pressure (≥140/≥90 mm Hg), and 46% (n = 140) had elevated total cholesterol. One third of farmers were found to be obese (35%; n = 110). The vast majority (83%; n = 255) had at least four risk factors for CVD based on the outcomes of the heart screening. The study findings in relation to obesity and the prevalence of multiple risk factors for CVD are a particular cause of concern and shed considerable light on the current excess burden of CVD among farmers in Ireland.

E-learning is the use of Information and Communication Technology (ICT) to provide online education and learning. E- Learning has now been integrated into the traditional teaching as the concept of 'blended learning' that combines digital learning with the existing traditional teaching methods to address the various challenges in the field of medical education. Structured e-learning activities were started in Melaka Manipal Medical College in 2009 via e-learning platform (MOODLE-Modular Object-Oriented Dynamic Learning Environment). The objective of the present study is to investigate the faculty opinions toward the existing e-learning activities, and to analyse the extent of adopting and integration of e-learning into their traditional teaching methods. A cross sectional study was conducted among faculties of Medicine and Dentistry using pre-tested questionnaires. The data was analyzed by using the statistical package for social science, SPSS, version 16.0. The result of our survey indicates that majority of our faculty (65.4%) held positive opinion towards e-learning. Among the few, who demonstrated reservations, it is attributed to their average level of skills and aptitude in the use of computers that was statistically significant (p<0.05). Our study brings to light the need for formal training as perquisite to support e-learning that enables smooth transition of the faculty from their traditional teaching methods into blended approach. Our results are anticipated to strengthen the existing e-learning activities of our college and other universities and convincingly adopt e-learning as a viable teaching and learning strategy.

Vaginismus is considered as one of the most common female psychosexual dysfunctions. Although the importance of using a multidisciplinary approach for assessment of vaginal penetration disorder is emphasized, the paucity of instruments for this purpose is clear. We designed a study to develop and investigate the psychometric properties of a multidimensional vaginal penetration disorder questionnaire (MVPDQ), thereby assisting specialists for clinical assessment of women with lifelong vaginismus (LLV). MVPDQ was developed using the findings from a thematic qualitative research conducted with 20 unconsummated couples from a former study, which was followed by an extensive literature review. Then, during a cross-sectional design, a consecutive sample of 214 women, who were diagnosed as LLV based on Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV-TR criteria completed MVPDQ and additional questions regarding their demographic and sexual history. Validation measures and reliability were tested by exploratory factor analysis and Cronbach's alpha coefficient via Statistical Package for the Social Sciences (SPSS) version 16. After conducting exploratory factor analysis, MVPDQ emerged with 72 items and 9 dimensions: Catastrophic cognitions and tightening, helplessness, marital adjustment, hypervigilance, avoidance, penetration motivation, sexual information, genital incompatibility, and optimism. Subscales of MVPDQ showed a significant reliability that varied between 0.70 and 0.87 and results of test-retest were satisfactory. The present study shows that MVPDQ is a valid and reliable self-report questionnaire for clinical assessment of women complaining of LLV. This instrument may assist specialists to make a clinical judgment and plan appropriately for clinical management.

During the last decades, there has been an alarming and dramatic increase in the number of cesarean births in both developed and undeveloped countries. This increase has not been clinically justified but, nevertheless, has raised an important number of issues. The aim of this study was to determine the risk factors associated with the high cesarean section rates in Lebanon. This study is based on a sample of 29,270 Lebanese women who were pregnant between 2000 and 2015. Among these, 14,327 gave birth by cesarean section and 14,943 gave birth vaginally. To identify the risk factors of cesarean section, logistic regression was applied as a statistical method using the SPSS statistical package. Of the 29,270 pregnant women included in the study, 49% had cesarean sections while 51% gave birth vaginally. Repeat cesarean section accounted for 23% while vaginal birth after cesarean accounted for only 0.2% of deliveries. In addition, weekdays were associated with a preference of providers to carry out more cesarean sections. According to an analysis of our data using logistic regression, the risk factors associated with the increase in cesarean section rates were advanced maternal age, elective cesarean section, malpresentation of fetus, multiple birth, prolonged pregnancy, prolonged labor, and fetal distress. Based on these results, it is recommended that a new health policy be implemented to reduce the number of unnecessary cesarean deliveries in Lebanon. Copyright © 2017 Australian College of Midwives.

Despite the set guidelines on Healthcare Waste Management in Kenya, mixing of different categories of waste, crude dumping and poor incineration are still a common phenomenon in public health facilities in Thika Subcounty, Kenya. Thika Subcounty generates 560 Kilograms of healthcare waste daily, which is risk to the many patients (admission rate of 26%). This may pose a potential environmental risk and be a source of disease diffusion. This research explored the adherence to healthcare waste management waste guidelines in health care facilities among the nurses and waste handlers. This was a cross sectional survey in which mixed methods were applied. A census and proportionate random sampling method were used. Quantitative data was analyzed using Statistical Package for Social Science (SPSS) version 20.0, while qualitative data was analyzed manually into themes. Full adherence to the seven waste disposal guidelines was low (16.3%). Knowledge on waste segregation, waste separation then disposal and means of transports were statistically significant in relation to adherence. The type of incinerator and burning status, protection maintenance and supply of adequate waste bins were also important to adherence level. Adherence level was low (16.3%,) and insignificantly different among nurses and waste handlers. From this finding, compliance remains a key challenge. Strategies targeted at contextualizing waste regulations and guidelines into local settings are necessary and important. Policy makers may design and implement standard incinerators across all the health facilities. This study is not exhaustive; therefore, it is necessary to carry out a study linking poor treatment and disposal of clinical waste to purported health outcomes in Kenya.

Awareness of appropriate waste management procedures and occupational safety measures is fundamental to achieving a safe work environment, and ensuring patient and staff safety. This study was conducted to assess the attitude of healthcare managers to medical waste management and occupational safety practices. This was a cross-sectional study conducted among 54 hospital administrators in Ebonyi state. Semi-structured questionnaires were used for qualitative data collection and analyzed with SPSS statistics for windows (2011), version 20.0 statistical software (Armonk, NY: IBM Corp). Two-fifth (40%) of healthcare managers had received training on medical waste management and occupational safety. Standard operating procedure of waste disposal was practiced by only one hospital (1.9%), while 98.1% (53/54) practiced indiscriminate waste disposal. Injection safety boxes were widely available in all health facilities, nevertheless, the use of incinerators and waste treatment was practiced by 1.9% (1/54) facility. However, 40.7% (22/54) and 59.3% (32/54) of respondents trained their staff and organize safety orientation courses respectively. Staff insurance cover was offered by just one hospital (1.9%), while none of the hospitals had compensation package for occupational hazard victims. Over half (55.6%; 30/54) of the respondents provided both personal protective equipment and post exposure prophylaxis for HIV. There was high level of non-compliance to standard medical waste management procedures, and lack of training on occupational safety measures. Relevant regulating agencies should step up efforts at monitoring and regulation of healthcare activities and ensure staff training on safe handling and disposal of hospital waste.

The study was performed on 20 (10 males, 10 females) roe deer (Capreolus capreolus) to investigate the concentration of cadmium, lead, mercury, and arsenic in the muscle tissue. They reside in forest and meadow, about 50 km distance from industrial activities and traffic. Samples were taken from the musculus biceps femoris of each deer without external contamination after shooting during the regular hunting season on a hunting area close to Eger in Hungary. The determination of heavy metal contents was carried out by inductively coupled plasma optical emission spectrometry (ICP-OES). The statistical analysis was performed by statistical package for the social sciences (SPSS) version 11.0. The measured residue concentration of cadmium was below the limit of detection in the roe deer meat indicating no health risk for the consumers. The average lead concentration (0.48 ± 0.21 mg/kg wet weight) exceeded the regulated maximum limit, but its calculated weekly intake was below the provisional tolerable weekly intake (PTWI). The residue level of mercury is not regulated and the average mercury content of roe deer meat (0.87 ± 0.40 mg/kg wet weight) was about half of PTWI, but the consumption of meat with the highest detected concentrations results in higher PTWI than recommended. The measured concentration of arsenic (0.27 ± 0.20 mg/kg wet weight) in the roe deer meat may not pose any health risk for the human consumers according to the PTWI set by the World Health Organization.

Ecological and Human Health Risk Assessment of Heavy Metal Content of Atmospheric Dry Deposition, a Case Study: Kermanshah, Iran.

The present study was intended to investigate the ecological and human health risk of cobalt, nickel, and vanadium in the atmospheric dry deposition of the Kermanshah city, Iran, in 2015. Totally 54 samples of atmospheric dry deposition were collected from the three regions of the city with different traffic intensity, and after acid digestion of the samples with ultrapure concentrated HNO 3 , the total contents of the metals were determined using inductively coupled plasma optical emission spectrometer (ICP-OES). Also, all statistical analyses were performed using the SPSS statistical package. The atmospheric dry deposition element contents increase according to the following descending order for both autumn seasons: Ni > Co > V. The results of potential ecological risk analysis demonstrated that metals in the samples are in low ecological risk levels, whereas the results of human health risk assessment showed that ingestion is the main exposure pathway of heavy metals in the dust to the local residents compared with inhalation and dermal pathways. Also, the upper limit of the 95% confidence interval (95% UCL) of hazard indices for non-carcinogenic risks of all analyzed metals in the dust samples was within the safe level for both children and adults. On the other hand, the carcinogenic risk levels of Co and Ni were all lower than the acceptable range (10 -6 -10 -4 ) to local citizens. Consequently, the results advocate the necessity of understanding the heavy metal content of atmospheric dry deposition and regular monitoring of air pollution.

To determine the frequency of occupational exposure to human immunodeficiency virus (HIV), the circumstances and predisposing factors, the high-risk groups, the extent to which exposures are reported and the post-exposure prophylaxis (PEP) utilized by health-care workers (HCWs) and students in a Ugandan hospital. Occupational exposure to HIV is a low but potential risk of HIV infection to health workers. Self-administered questionnaire was given to 224 participants (including 98 HCWs and 126 students) in Mbarara Hospital, Uganda. Data were analysed with descriptive statistics using the Statistical Package for the Social Sciences version 15.0 (SPSS Inc, Chicago, IL, USA). Of the 224 participants surveyed, 19.2% reported having sustained injection needle stick injuries in the previous year, of which 4.46% occurred with HIV-infected blood. Other reported injuries were cannula needle stick injury (0.89%), suture needle stick injuries (3.13%), scalpel cut injuries (0.45%) and muco-cutaneous contamination (10.27%). The most affected groups were nurses-midwives for scalpel injuries and students for stick injuries. The predisposing factors reported included lack of protective devices and recapping of needles. Exposures were under-reported. Uptake of PEP was also low. Occupational exposure to HIV presents a conflict situation for HCWs. It remains a frequent occurrence particularly among student nurses-midwives, despite being avoidable. Its prophylactic treatment is hampered by poor reporting and investigation of exposures, and poor access to PEP. Strict adherence to universal precaution and proper handling of occupational exposure to HIV should be encouraged. © 2011 The Authors.

Health service delivery is a key pillar of the health system management .The World Health Organization recently emphasized the need to develop adolescent -friendly health services to improve the care provided to young people throughout the world. However, there is limited peer reviewed literature on this subject therefore necessitating assessment of whether the existing health facilities are prepared to implement the adolescent friendly health services. Adolescent friendly health services remains a relatively new and sensitive area mainly due to restrictive norms and policies guiding the services. After International Conference on Population and Development in 1994, countries started implementing adolescent friendly health services. The Government of Kenya together with partners in an attempt to address the health challenges came up with the Adolescent package of care (APOC) in 2013 whose guidelines were finalized in November 2014 and released for use by service providers . Despite this package of care, there is still ineffective staff capacity in relation to skills and knowledge gap of health professionals, training needs, health resources as well as health system factors that can affect implementation of AFHS. The study explored ways of mitigating or addressing the barriers to implementation of these services. The study used both quantitative and qualitative approaches to collect data. The study utilized survey research adapting descriptive cross sectional design and semi-structured questionnaire to interview 348 health care providers and 472 adolescents in Mam Lucy Kibaki Hospital from 3rd May 2014 to 16 June 2014 .The key informants were mainly nurses, clinical officers and Medical doctors who were working at the health service delivery area at the time of study and were interviewed using an interview guide. The managers at the hospital were interviewed using an in-depth interview guide while the adolescents were interviewed through interview guide and focused group discussion. Quantitative data was analyzed using Statistical Package for Social Sciences (SPSS) Version 18.0. Descriptive statistics and chi-square tests were performed to determine significant associations. The study established that sex, age, level of education and adolescent awareness about existence of friendly health services offered were significantly associated with utilization at p<0.05. Long queues, unfavorable working hours and lack of money negatively affected consumption of AFHS.The study concluded that the utilization of health services among the adolescents was low largely due to unfriendliness of the health care providers at health facilities and lack of awareness of AFHS services. In view of the findings, this study recommends need for the Government through the Ministry of Health and partners in health service provision to increase the number of AFHS and ensure that the recommendations of Adolescent Package of care is implemented fully with good evaluation strategies in place. Laborious awareness drives to sensitize the adolescents about the available services through rigorous health education and increased involvement of both parents/guardians and teachers to scale up implementation are also recommended.

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.

2015-01-01

The informR package greatly simplifies the analysis of complex event histories in 𝖱 by providing user friendly tools to build sufficient statistics for the relevent package. Historically, building sufficient statistics to model event sequences (of the form a→b) using the egocentric generalization of Butts’ (2008) relational event framework for modeling social action has been cumbersome. The informR package simplifies the construction of the complex list of arrays needed by the rem() model fitting for a variety of cases involving egocentric event data, multiple event types, and/or support constraints. This paper introduces these tools using examples from real data extracted from the American Time Use Survey. PMID:26185488

2008-10-29

This paper presents the R/Bioconductor package minet (version 1.1.6) which provides a set of functions to infer mutual information networks from a dataset. Once fed with a microarray dataset, the package returns a network where nodes denote genes, edges model statistical dependencies between genes and the weight of an edge quantifies the statistical evidence of a specific (e.g transcriptional) gene-to-gene interaction. Four different entropy estimators are made available in the package minet (empirical, Miller-Madow, Schurmann-Grassberger and shrink) as well as four different inference methods, namely relevance networks, ARACNE, CLR and MRNET. Also, the package integrates accuracy assessment tools, like F-scores, PR-curves and ROC-curves in order to compare the inferred network with a reference one. The package minet provides a series of tools for inferring transcriptional networks from microarray data. It is freely available from the Comprehensive R Archive Network (CRAN) as well as from the Bioconductor website.

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.

Biological studies involve a growing number of distinct high-throughput experiments to characterize samples of interest. There is a lack of methods to visualize these different genomic datasets in a versatile manner. In addition, genomic data analysis requires integrated visualization of experimental data along with constantly changing genomic annotation and statistical analyses. We developed GenomeGraphs, as an add-on software package for the statistical programming environment R, to facilitate integrated visualization of genomic datasets. GenomeGraphs uses the biomaRt package to perform on-line annotation queries to Ensembl and translates these to gene/transcript structures in viewports of the grid graphics package. This allows genomic annotation to be plotted together with experimental data. GenomeGraphs can also be used to plot custom annotation tracks in combination with different experimental data types together in one plot using the same genomic coordinate system. GenomeGraphs is a flexible and extensible software package which can be used to visualize a multitude of genomic datasets within the statistical programming environment R.

to analyse the effects of relaxation as a nursing intervention on the depression levels of hospitalised women with high-risk pregnancies. a randomised clinical trial realised in a reference centre for high-risk pregnancies. The sample consisted of 50 women with high-risk pregnancies (25 in the control group and 25 in the intervention group). The Benson relaxation technique was applied to the intervention group for five days. Control variables were collected using a predesigned form, and the signs and symptoms of depression were evaluated using the Edinburgh Postnatal Depression Scale (EPDS). The Statistical Package for Social Sciences (SPSS), version 20.0, was used with a significance level of 5%. The Wilcoxon and paired t-tests were used to evaluate depression levels between two timepoints. Using categorical data, the McNemar test was used to analyse differences in depression severity before and after the intervention. depression levels decreased in the intervention group five days after the relaxation technique was applied (4.5 ± 3, p<0.05) compared with the levels at the first timepoint (10.3±5.9). as a nursing intervention, relaxation was effective in decreasing the symptoms of depression in hospitalised women with high-risk pregnancies. analisar os efeitos do relaxamento como uma intervenção de enfermagem sobre os níveis de depressão de mulheres internadas com gravidez de alto risco. ensaio clínico randomizado realizado em um centro de referência para gravidez de alto risco A amostra foi composta de 50 mulheres com gravidez de alto risco (25 no grupo controle e 25 no grupo intervenção).

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

Wolff, Hans-Georg; Preising, Katja

2005-02-01

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/.

Data Analysis for the Behavioral Sciences Using SPSS

Lawner Weinberg, Sharon; Knapp Abramowitz, Sarah

2002-04-01

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.

The article presents the results of a study of the soil surface seasonal activity of two species of julidae, widely spread in the Balkan Peninsula: Leptoiulus trilineatus (C.L. Koch, 1847) and Megaphyllum trassylvanicum (Verhoeff, 1897). The material was collected by means of pitfall traps between May 2007 and May 2009 in natural and urban habitats exposed to varying degrees of anthropogenic pressure. In the study period 1474 specimens of L. trilineatus and 618 specimens of M. transsylvanicum were collected. The impact of the soil and air temperature and humidity on the seasonal activity of both species was measured through statistical analysis. The statistical data processing was conducted using SPSS 9.0 and StatPlus 3.5.3 software packages. L. trilineatus and M. trassylvanicum are polytopic, mesophilic and mesotermic species with year-round activity in the studied area. There is no statistically significant correlation between the degree of anthropogenic impact and the activity of the two species. Leptoiulus trilineatus shows equal preference for both urban and natural habitats in the studied area. The species demonstrates the typical of all millipedes bimodal activity, which is the highest in spring and the beginning of winter - in the periods from March to May and from November to December. The coefficients of correlation dependence of L. trilineatus activity on the tested abiotic environmental factors are not statistically significant. The Pearson-Brave coefficient which measures the effect of soil humidity on species activity is 0.417, which shows a positive correlation. M. trassylvanicum has the highest frequency in urban biotops such as parks in the urban and suburban areas of Shumen and in the coniferous habitats on the Shumen Plateau. In this area the species demonstrates its highest activity in spring and summer (from February to July). The abiotic factors with statistically significant effect on the soil surface activity of M. trassylvanicum are the soil and air temperature - the values of the Pearson-Brave correlation coefficients are 0.708 and 0.586 respectively.

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.

For the analysis of low-statistics counting experiments, a traditional nonlinear least squares minimization routine may not always provide correct parameter and uncertainty estimates due to the assumptions inherent in the algorithm(s). In response to this, a user-friendly Python package (SATLAS) was written to provide an easy interface between the data and a variety of minimization algorithms which are suited for analyzinglow, as well as high, statistics data. The advantage of this package is that it allows the user to define their own model function and then compare different minimization routines to determine the optimal parameter values and their respective (correlated) errors. Experimental validation of the different approaches in the package is done through analysis of hyperfine structure data of 203Fr gathered by the CRIS experiment at ISOLDE, CERN.

Exploration of DNA methylation and its impact on various regulatory mechanisms has become a very active field of research. Simultaneously there is an arising need for tools to process and analyse the data together with statistical investigation and visualisation. MethVisual is a new application that enables exploratory analysis and intuitive visualization of DNA methylation data as is typically generated by bisulfite sequencing. The package allows the import of DNA methylation sequences, aligns them and performs quality control comparison. It comprises basic analysis steps as lollipop visualization, co-occurrence display of methylation of neighbouring and distant CpG sites, summary statistics on methylation status, clustering and correspondence analysis. The package has been developed for methylation data but can be also used for other data types for which binary coding can be inferred. The application of the package, as well as a comparison to existing DNA methylation analysis tools and its workflow based on two datasets is presented in this paper. The R package MethVisual offers various analysis procedures for data that can be binarized, in particular for bisulfite sequenced methylation data. R/Bioconductor has become one of the most important environments for statistical analysis of various types of biological and medical data. Therefore, any data analysis within R that allows the integration of various data types as provided from different technological platforms is convenient. It is the first and so far the only specific package for DNA methylation analysis, in particular for bisulfite sequenced data available in R/Bioconductor enviroment. The package is available for free at http://methvisual.molgen.mpg.de/ and from the Bioconductor Consortium http://www.bioconductor.org.

2013-01-01

Background In medical informatics, psychology, market research and many other fields, researchers often need to analyze and model ranking data. However, there is no statistical software that provides tools for the comprehensive analysis of ranking data. Here, we present pmr, an R package for analyzing and modeling ranking data with a bundle of tools. The pmr package enables descriptive statistics (mean rank, pairwise frequencies, and marginal matrix), Analytic Hierarchy Process models (with Saaty’s and Koczkodaj’s inconsistencies), probability models (Luce model, distance-based model, and rank-ordered logit model), and the visualization of ranking data with multidimensional preference analysis. Results Examples of the use of package pmr are given using a real ranking dataset from medical informatics, in which 566 Hong Kong physicians ranked the top five incentives (1: competitive pressures; 2: increased savings; 3: government regulation; 4: improved efficiency; 5: improved quality care; 6: patient demand; 7: financial incentives) to the computerization of clinical practice. The mean rank showed that item 4 is the most preferred item and item 3 is the least preferred item, and significance difference was found between physicians’ preferences with respect to their monthly income. A multidimensional preference analysis identified two dimensions that explain 42% of the total variance. The first can be interpreted as the overall preference of the seven items (labeled as “internal/external”), and the second dimension can be interpreted as their overall variance of (labeled as “push/pull factors”). Various statistical models were fitted, and the best were found to be weighted distance-based models with Spearman’s footrule distance. Conclusions In this paper, we presented the R package pmr, the first package for analyzing and modeling ranking data. The package provides insight to users through descriptive statistics of ranking data. Users can also visualize ranking data by applying a thought multidimensional preference analysis. Various probability models for ranking data are also included, allowing users to choose that which is most suitable to their specific situations. PMID:23672645

Is Inferior Alveolar Nerve Block Sufficient for Routine Dental Treatment in 4- to 6-year-old Children?

PubMed Central

Erfanparast, Leila; Sheykhgermchi, Sanaz; Ghanizadeh, Milad

2017-01-01

Introduction Pain control is one of the most important aspects of behavior management in children. The most common way to achieve pain control is by using local anesthetics (LA). Many studies describe that the buccal nerve innervates the buccal gingiva and mucosa of the mandible for a variable extent from the vicinity of the lower third molar to the lower canine. Regarding the importance of appropriate and complete LA in child-behavior control, in this study, we examined the frequency of buccal gingiva anesthesia of primary mandibular molars and canine after inferior alveolar nerve block injection in 4- to 6-year-old children. Study design In this descriptive cross-sectional study, 220 4- to 6-year-old children were randomly selected and entered into the study. Inferior alveolar nerve block was injected with the same method and standards for all children, and after ensuring the success of block injection, anesthesia of buccal mucosa of primary molars and canine was examined by stick test and reaction of child using sound, eye, motor (SEM) scale. The data from the study were analyzed using descriptive statistics and statistical software Statistical Package for the Social Sciences (SPSS) version 21. Results The area that was the highest nonanesthetized was recorded as in the distobuccal of the second primary molars. The area of the lowest nonanesthesia was also reported in the gingiva of primary canine tooth. Conclusion According to this study, in 15 to 30% of cases, after inferior alveolar nerve block injection, the primary mandibular molars’ buccal mucosa is not anesthetized.

To investigate the disability due to musculoskeletal disorders of the upper extremities in heavy industry workers. The population under study consisted of 802 employees, both white- and blue-collar, working in a shipyard industry in Athens, Greece. Data were collected through the distribution of questionnaires and the recording of individual and job-related characteristics during the period 2006-2009. The questionnaires used were the Quick Disabilities of the Arm, Shoulder and Hand (QD) Outcome Measure, the Work Ability Index (WAI) and the Short-Form-36 (SF-36) Health Survey. The QD was divided into three parameters - movement restrictions in everyday activities, work and sports/music activities - and the SF-36 into two items, physical and emotional. Multiple linear regression analysis was performed by means of the SPSS v.22 for Windows Statistical Package. The answers given by the participants for the QD did not reveal great discomfort regarding the execution of manual tasks, with the majority of the participants scoring under 5%, meaning no disability. After conducting multiple linear regression, age revealed a positive association with the parameter of restrictions in everyday activities (b = 0.64, P = 0.000). Basic education showed a statistically significant association regarding restrictions during leisure activities, with b = 2.140 ( P = 0.029) for compulsory education graduates. WAI's final score displayed negative charging in the regression analysis of all three parameters, with b = -0.142 ( P = 0.0), b = -0.099 ( P = 0.055) and b = -0.376 ( P = 0.001) respectively, while the physical and emotional components of SF-36 associated with movement restrictions only in daily activities and work. The participants' specialty made no statistically significant associations with any of the three parameters of the QD. Increased musculoskeletal disorders of the upper extremity are associated with older age, lower basic education and physical and mental/emotional health and reduced working ability.

Appendectomy is generally conducted as open or by laparoscopic surgical techniques under general anesthesia. This study aims to compare the anesthetic costs of the patients, who underwent open or laparoscopic appendectomy under general anesthesia. The design is retrospective and records of 379 patients who underwent open or laparoscopic appendectomy under general anesthesia, falling under the category of I-III risk group according to the American Society of Anesthesiologists (ASA) classification between the years 2011 and 2013, and aged 18-77. Open (Group I) or laparoscopic (Group II) appendectomy operation under general anesthesia were evaluated retrospectively by utilizing hospital automation and anesthesia observation records. This study evaluated the anesthesia time of the patients and total costs (Turkish Lira ₺, US dollar $) of anesthetic agents used (induction, maintenance), necessary medical materials (connecting line, endotracheal tube, airway, humidifier, branule, aspiration probe), and intravenously administered fluids were evaluated. We used Statistical Package for the Social Sciences software (SPSS version 17.0) for statistical analysis. Of the patients, 237 were males (62.53%) and 142 were females (37.47%). Anesthesia time limits were established as 70.30 ± 30.23 minute in Group I and 74.92 ± 31.83 minute in Group II. Mean anesthesia administration cost per patient was found to be 78.79 ± 30.01₺ (39.16 ± 14.15$) in Group I and 83.09 ± 26.85₺ (41.29 ± 13.34$) in Group II (P > 0.05). A correlation was observed between cost and operation times (P = 0.002, r = 0.158). Although a statistical difference was not established in this study in terms of time and costs in appendectomy operations conducted as open and laparoscopically, changes may occur in time in market conditions of drugs, patent rights, legal regulations, and prices. Therefore, we believe that it would be beneficial to update and revise cost analyses from time to time.

Background: Effective pain relief therapy after caesarean section is essential for the parturient's comfort and early ambulation. Paracetamol has an excellent safety profile when compared to opioids. Aim: To assess and evaluate the effect of oral, rectal, and intravenous infusion of paracetamol for post-operative analgesia in women undergoing caesarean section under spinal anaesthesia. Settings and Design: We conducted a prospective, randomized controlled study (18-35 years of age) of the ASA- I and II parturient scheduled for lower segment caesarean section were included. Methods and Materials: They were randomly allocated to 3 groups of 50 each. Group A received oral paracetamol tablet 650mg (1 tablet) 20min before shifting to operation room, group B received rectal paracetamol suppository 35-45 mg/kg immediately after spinal anaesthesia and group C received i.v. paracetamol infusion of 10-15mg/kg over 15min duration 20min before finishing the operation. Duration of analgesia was evaluated as primary outcome and other parameters as secondary outcome. Statistical Tests: All statistical analyses were performed using the SPSS statistical package 17.0 version. Results were analyzed using Chi Square test for non-parametric data and ANOVA for parametric data. P value of less than 0.05 was considered significant and less than 0.001 as highly significant. Results: Duration of analgesia was significantly longer in group B as compared to group A and C. The requirement of supplemental rescue analgesia was also lower in group B compared to group A and C. No significant haemodynamic derangements and adverse effects were noted among all the three groups. Conclusion: Paracetamol when given rectally improves the quality and duration of postoperative analgesia to a greater extent as compared to oral and intravenous route of paracetamol without any side effects.

Members of triggering receptor expressed on myeloid cells (TREM) family are known as immunmodulators in several infectious or noninfectious inflammatory disorders. The information about their role in viral infections is very limited. To enlighten if there is a relation between soluble TREM-1(sTREM-1) and a viral infection, Crimean Congo Haemorrhagic Fever (CCHF), we investigated the levels of sTREM-1 in the sera of 39 CCHF patients both at admission and at recovery and compared with 40 healthy controls by using microELISA technique. Statistical analysis was made by using Statistical Package for Social Sciences (SPSS) for Windows 20 programme. Value of P < 0.05 was accepted as significant for statistical analyses. Median sTREM-1 level was higher in CCHF group when compared to the control group (1,961 vs. 151.1 pg/ml, respectively; P < 0.001). In CCHF patients, sTREM-1 levels were significantly decreased at recovery compared to initial level measured at hospital admission (1,961 vs. 948 pg/ml, respectively; P = 0.019). ΔsTREM-1 is correlated with ΔCRP, ΔWBC, and ΔPlt. We found that serum levels of sTREM-1 higher than 405.9 pg/ml existed as a cut off point for differentiating CCHF patients and control group with a sensitivity of 94.9% and specifity of 87.5%. It is proved that sTREM-1 is increased and correlates with the clinical and laboratory findings in CCHF, a viral infection characterized by activation of inflammation. This finding may lead new studies to enlighten the pathogenesis of infections developing by activation of inflammatory cascades and high level cytokine releases, especially. J. Med.

A prospective study aimed to suggest easy and simple reproducible ventricular site that will be basic measurement plane and normal dimension determined, correlated to sizes of infants for comparative evaluation of hydrocephalous infants and should be reproducible in follow-up. A prospective study done in University of Benin Teaching Hospital Benin, Nigeria. This study used 50 consecutive infants with Ultrasound scan (US) diagnosis of hydrocephalus and a control group of 50 US normal from 1(st) January 2007 to 30(th) June 2008. The infants were scan through the mid-patent anterior fontanelle in sagittal, and transverse planes with minor angulations to properly outline the ventricles and the position of measurement determined at the foramen of Monro of lateral ventricles and the diameter measured. The infants' weight, crown-heel length, and head circumference were measured and body mass index (BMI) calculated and correlated to lateral ventricular measurement. Data analysis was conducted using the Statistical Package for Social Sciences (SPSS Inc, USA), Version 11.0. There was no statistically sex and age-related difference. There is statistically comparative high mean weight and height and lower BMI in hydrocephalic infants as against the control group (P < 0.001). The mean head circumference for hydrocephalus was 45.6 (± 10.5 standard deviation [SD]), whereas the control group was 35.9 (± 2.7 SD) with P < 0.001. The mean diameter of the anterior horn of left and right lateral ventricles at the level of foramen of Monro in hydrocephalic subjects is 18.4 mm ± 14.3 mm and 20.1 mm ± 16.8 mm with median diameter of 14.1 mm and 15.2 mm, respectively, whereas control group is 2.5 mm ± 0.6 mm and 2.5 mm ± 0.7 mm with median diameter of 2.5 mm and 2.4 mm, respectively. Transfontanelle US was found highly useful in investigation of hydrocephalous in infant.

Background: Propofol has been used for the induction and maintenance of anesthesia. However, patients experience vascular pain during its injection. Aims: The objective of this study was to compare the effect of the lipid type used in propofol preparations and that of lidocaine on the immediate and delayed vascular pain induced by propofol administration. Materials and Methods: In this double-blinded clinical study, 150 patients at American Society of Anesthesiologists level I-II were randomly divided into three equally sized groups. A propofol with medium and long-chain triglycerides (propofol-MCT/LCT) was administered to the first group. The second group received propofol containing propofol-LCT, and the third group received propofol-LCT and pretreatment lidocaine 20 mg. The incidence and the intensity of immediate (during injection) and delayed injection pain (after 20 s) were evaluated on a verbal analog scale (1–10) until patients’ unconsciousness. Statistical Analysis: Sample size was calculated with SigmaPlot version 12.5 software. Data were analyzed with Statistical Package for the Social Sciences (SPSS) version 16, one-way analysis of variance, and post-hoc Tukey. P < 0.05 was considered statistically significant. Results: The demographic parameters of the three groups were similar. The lidocaine group experienced the least immediate vascular pain. The intensity of pain was highest in the propofol-LCT group (P = 0.04). Additionally, the intensity of delayed pain was lowest in the propofol-MCT/LCT group (P = 0.01). The incidence of pain associated with the propofol administration was 26.5, 44, and 18%, respectively, in propofol-MCT/LCT, propofol-LCT, and lidocaine and propofol-LCT groups. Conclusion: The results indicate an effect of the lipid type on delayed pain reduction, especially propofol-MCT/LCT. On the other hand, the lidocaine decreases immediate propofol-LCT vascular pain.

The purpose of this study was to locate traditionally-used landmarks in two-dimensional (2D) images and newly-suggested ones in three-dimensional (3D) images (cone-beam computer tomographies [CBCTs]) and determine possible relationships between them to categorize patients with Class II-1 malocclusion. CBCTs from 30 patients diagnosed with Class II-1 malocclusion were obtained from the University of Alberta Graduate Orthodontic Program database. The reconstructed images were downloaded and visualized using the software platform AVIZO ® . Forty-two landmarks were chosen and the coordinates were then obtained and analyzed using linear and angular measurements. Ten images were analyzed three times to determine the reliability and measurement error of each landmark using Intra-Class Correlation coefficient (ICC). Descriptive statistics were done using the SPSS statistical package to determine any relationships. ICC values were excellent for all landmarks in all axes, with the highest measurement error of 2mm in the y-axis for the Gonion Left landmark. Linear and angular measurements were calculated using the coordinates of each landmark. Descriptive statistics showed that the linear and angular measurements used in the 2D images did not correlate well with the 3D images. The lowest standard deviation obtained was 0.6709 for S-GoR/N-Me, with a mean of 0.8016. The highest standard deviation was 20.20704 for ANS-InfraL, with a mean of 41.006. The traditional landmarks used for 2D malocclusion analysis show good reliability when transferred to 3D images. However, they did not reveal specific skeletal or dental patterns when trying to analyze 3D images for malocclusion. Thus, another technique should be considered when classifying 3D CBCT images for Class II-1malocclusion. Copyright © 2017 CEO. Published by Elsevier Masson SAS. All rights reserved.

SPSS and SAS programs for addressing interdependence and basic levels-of-analysis issues in psychological data.

PubMed

O'Connor, Brian P

2004-02-01

Levels-of-analysis issues arise whenever individual-level data are collected from more than one person from the same dyad, family, classroom, work group, or other interaction unit. Interdependence in data from individuals in the same interaction units also violates the independence-of-observations assumption that underlies commonly used statistical tests. This article describes the data analysis challenges that are presented by these issues and presents SPSS and SAS programs for conducting appropriate analyses. The programs conduct the within-and-between-analyses described by Dansereau, Alutto, and Yammarino (1984) and the dyad-level analyses described by Gonzalez and Griffin (1999) and Griffin and Gonzalez (1995). Contrasts with general multilevel modeling procedures are then discussed.

In nonexperimental data, at least three possible explanations exist for the association of two variables x and y: (1) x is the cause of y, (2) y is the cause of x, or (3) an unmeasured confounder is present. Statistical tests that identify which of the three explanatory models fits best would be a useful adjunct to the use of theory alone. The present article introduces one such statistical method, direction dependence analysis (DDA), which assesses the relative plausibility of the three explanatory models on the basis of higher-moment information about the variables (i.e., skewness and kurtosis). DDA involves the evaluation of three properties of the data: (1) the observed distributions of the variables, (2) the residual distributions of the competing models, and (3) the independence properties of the predictors and residuals of the competing models. When the observed variables are nonnormally distributed, we show that DDA components can be used to uniquely identify each explanatory model. Statistical inference methods for model selection are presented, and macros to implement DDA in SPSS are provided. An empirical example is given to illustrate the approach. Conceptual and empirical considerations are discussed for best-practice applications in psychological data, and sample size recommendations based on previous simulation studies are provided.

To improve the development of the Chinese version of Perceived Nursing Work Environment (C-PNWE) scale by examination and application and to explore the nurses' perception of their working environment in a hospital. The C-PNWE scale was translated and revised from the PNWE scale. The least of perfection is that the development of C-PNWE ignored that the psychometric properties of the PNWE instrument were established of critical care nurses and further application and testing of the PNWE in various patient care settings were recommended. This is a cross-sectional design. Nurses from different departments of a hospital were sampled by convenience sampling and investigated by self-administrated questionnaire. Data obtained through questionnaires were analysed by descriptive statistical analyses and profile analyses using the Statistical Package for the Social Sciences (SPSS) Chinese version 17.0 software. The coincident and level profile analyses indicated that these groups can merge into one group, and the profile of measurement result of this merged group would not exhibit flatness. Among six dimensions of C-PNWE scale, the Staffing and Resource Adequacy got the lowest average score. Among 41 items, 'Opportunity for staff nurse to participate in policy decisions' got the lowest mean. The C-PNWE scale shows good psychometric properties and can be used to explore nurses' perspectives of the nursing practice environment in China. And the situation of nurses' perceived working environment in China needs further study. Shaping nursing practice environments to promote desired outcomes requires valid and reliable measures to assess practice environments prior to, during and following efforts to implement change. The C-PNWE scale can be a useful measurement tool for administrators to improve the nursing work environment in China. © 2013 John Wiley & Sons Ltd.

Gripe water (GW) administration to young infants is common practice in this part of country. In order to ascertain why mothers administer gripe water to their infants and to find out what benefits or health risks it poses, we proposed to study the practice of mothers giving GW to their babies. Three hundred and thirty five eligible mothers of infants aged 1-6 months (who after qualifying inclusion and exclusion criteria of the study) who attended the well baby clinic during the study period, were interviewed using a semi structured questionnaire which contained both open and close ended questions after obtaining informed written consent. The study population was then divided into two groups based on administration of GW or not and the results were compared and analysed among the two groups using odds ratio with 95% C.I. For calculation of statistics, the statistical package SPSS 13 was used. 64.18% of the mothers were administering GW for their infants. Most mothers believed that GW helps in digestion and prevents stomach ache. Infantile colic, vomiting and constipation were common in GW administered infants, when compared to those who did not receive GW and the difference was significant with p-values of 0.0001, 0.0373, 0.0007respectively. GW administration is a common problem in infants and remains a significant challenge that thwarts exclusive breast feeding. More over GW administration does not seem to prevent infantile colic and on the other hand, may be associated with vomiting and constipation. Misconceptions prevailing among mothers have to be removed by effective counseling so that the mothers are aware of safe and healthy feeding practices to be adopted for feeding their babies.

The purposes of this study were to apply a logic model to plan and implement an evidence-based management (EBMgt) educational training program for healthcare administrators and to examine whether a logic model is a useful tool for evaluating the outcomes of the educational program. The logic model was used as a conceptual framework to guide the investigators in developing an EBMgt educational training program and evaluating the outcomes of the program. The major components of the logic model were constructed as inputs, outputs, and outcomes/impacts. The investigators delineated the logic model based on the results of the needs assessment survey. Two 3-hour training workshops were delivered to 30 participants. To assess the outcomes of the EBMgt educational program, pre- and post-tests and self-reflection surveys were conducted. The data were collected and analyzed descriptively and inferentially, using the IBM Statistical Package for the Social Sciences (SPSS) 22.0. A paired sample t-test was performed to compare the differences in participants' EBMgt knowledge and skills prior to and after the training. The assessment results showed that there was a statistically significant difference in participants' EBMgt knowledge and information searching skills before and after the training (p< 0.001). Participants' confidence in using the EBMgt approach for decision-making was significantly increased after the training workshops (p< 0.001). Eighty-three percent of participants indicated that the knowledge and skills they gained through the training program could be used for future management decision-making in their healthcare organizations. The overall evaluation results of the program were positive. It is suggested that the logic model is a useful tool for program planning, implementation, and evaluation, and it also improves the outcomes of the educational program.

The high levels of indebtedness and deficit of Spain's autonomous communities as a consequence of the national and European economic crisis have caused radical changes in the Spanish National Health Service. At the present time, the economic crisis is seriously affecting nurses in several European countries, and especially in Spain. The aim of this study was to analyse whether nursing students' perceptions of economic crisis influence their levels of burnout and engagement in relation to their studies. We have also tried to clarify the relationship of sociodemographic variables (age and gender) and personal control factors (self-efficacy, locus of control and success) with these factors. This was a transversal study based on descriptive and inferential statistical analysis. Analysis of the quantitative data was performed using Statistical Package for Social Sciences, IBM 19.0 (SPSS, 2010). 166 nursing students participated in the study, comprising 142 women and 24 men studying in Schools of Nursing in the North of Spain. They completed various questionnaires to gather information on sociodemographic variables and measure burnout, engagement, locus of control, expectations of success and perceptions of threat due to the economic crisis. Higher perception of economic crisis by the students is related to higher scores for burnout and lower scores for engagement. The scores for burnout were also positively predicted by external locus of control and negatively predicted by perception of self-efficacy. The age of participants is related to lower levels of burnout and higher levels of engagement. Finally, expectation of success also positively predicted the level of engagement. The results demonstrate the importance of the perceptions of the economic crisis on the development of burnout and engagement among nursing students. Copyright © 2017 Elsevier Ltd.

To investigate the etiology and the epidemiological profile of patients with vulvovaginal candidiasis (VVC) and predisposing factors. Vaginal secretions were streaked in Sabouraud agar and yeast samples were isolated and identified by Polymerase Chain Reaction (PCR). Demographic and clinical data were obtained with a questionnaire. For statistical analysis, the Student's t-test, the χ² and Fischer tests were applied as needed using the Statistical Package for Social Sciences (SPSS) software, with the level of significance set at 5%. Sixty-nine patients aged from 15 to 52 years were evaluated. They were predominantly white (79.7%), with higher education (58%), married (56.5%) and sexually active (97.1%). Among them, 34.8% were pregnant, 7.2% diabetic, 1.4% seropositive for AIDS, and 36.2% were using oral contraceptives. Recent antibiotic therapy was mentioned by 13% of the patients, and antifungal or anti-trichomonas therapy was mentioned by 5.8 and 1.4% of the patients, respectively. Corticosteroid use was reported by 2.9% and antineoplastic by 1.4%. Vaginal discharge and itching were the main complaints (97.1 and 73.9%), followed by burning (63.8%) and erythema (63.8%). When present, the vaginal flow was predominantly white (88.1%) or lumpy (86.6%). The diagnosis was confirmed by culture in 55 (79.7%) patients, with mixed infections in 4 patients. The most prevalent species was C. albicans, followed by C. glabrata (one monoinfection and two mixed infections with C. albicans). C. lusitaniae and C. albicans were also identified in mixed infections (two patients). Despite the high culture positivity and clinical data characteristic of VVC, the symptoms were not pathognomonic. C. albicans is the most prevalent species, but other species are also involved in VVC etiology, such as the emergence of C. lusitaniae.

Research that explores being a parent or grandparent with musculoskeletal problems has been fairly limited to date. The aim of this study was to describe the experience of parenting in the context of back pain (BP), ankylosing spondylitis (AS) and rheumatoid arthritis (RA), with a particular focus on the extent and nature of childcare experiences and to compare these experiences across the three groups. In addition, the possible reasons for these reported experiences, the availability of advice and support and the development of strategies for coping were explored using a cross-sectional descriptive survey. A total of 448 participants was recruited from relevant charitable organizations and the National Health Service (280 with BP, 106 with AS and 62 with RA). A combination of opportunistic and random sampling was used. Quantitative data were analysed with appropriate descriptive and inferential statistics using Statistical Package for the Social Sciences (SPSS version 10). Qualitative data were analysed using content analysis. Results indicate that a high proportion of all groups experienced a wide range of difficulties with parenting (81% BP, 77% AS, 97% RA). The most prevalent problems were similar for all three groups: lifting baby/child from the floor or cot, encouraging children/grandchildren to help with domestic chores and keeping up (in terms of energy) with children/grandchildren. However, the RA group reported having greater difficulties than the other two groups. Very little advice was offered to participants with parenting difficulties which may indicate a gap in service provision. However, a wide range of strategies for coping were described by respondents. The study highlighted a need for healthcare professionals to develop a greater awareness of parenting issues and to provide opportunities for these issues to be addressed.

Background: The accelerating effect of plasma rich in growth factors (PRGFs) in the healing of extraction sockets has been demonstrated by some studies. The aim of the present study was to histologically and histomorphometrically evaluate whether bone formation would increase by the combined use of PRGF and demineralized freeze-dried bone allograft (DFDBA). Materials and Methods: In four female dogs, the distal root of the second, third and fourth lower premolars were extracted bilaterally and the mesial roots were preserved. The extraction sockets were randomly divided into DFDBA + PRGF, DFDBA + saline or control groups. Two dogs were sacrificed after 2 weeks and two dogs were sacrificed after 6 weeks. The extraction sockets were evaluated from both histological and histomorphometrical aspects. The data were analyzed by Mann-Whitney followed by Kruskal-Wallis tests using the Statistical Package for the Social Sciences version 20 (SPSS Inc., Chicago, IL, USA). Significant levels were set at 0.05. Results: The least decrease in socket height was observed in the DFDBA + PRGF group (0.73 ± 0.42 mm). The least decrease in the coronal portion was observed in the DFDBA + PRGF group (1.38 ± 1.35 mm²). The least decrease in the middle surface was observed in the DFDBA group (0.61 ± 0.80 mm²). The least decrease in the apical portion was observed in the DFDBA group (0.34 ± 0.39 mm²). Conclusion: The present study showed better socket preservation subsequent to the application of DFDBA and PRGF combination in comparison with the two other groups. However, the difference was not statistically significant. PMID:25225559

Abstract The purpose of the study was to establish a mathematical model for correlating the combination of ultrasonography and noncontrast helical computerized tomography (NCHCT) with the total energy of Holmium laser lithotripsy. In this study, from March 2013 to February 2014, 180 patients with single urinary calculus were examined using ultrasonography and NCHCT before Holmium laser lithotripsy. The calculus location and size, acoustic shadowing (AS) level, twinkling artifact intensity (TAI), and CT value were all documented. The total energy of lithotripsy (TEL) and the calculus composition were also recorded postoperatively. Data were analyzed using Spearman's rank correlation coefficient, with the SPSS 17.0 software package. Multiple linear regression was also used for further statistical analysis. A significant difference in the TEL was observed between renal calculi and ureteral calculi (r = –0.565, P < 0.001), and there was a strong correlation between the calculus size and the TEL (r = 0.675, P < 0.001). The difference in the TEL between the calculi with and without AS was highly significant (r = 0.325, P < 0.001). The CT value of the calculi was significantly correlated with the TEL (r = 0.386, P < 0.001). A correlation between the TAI and TEL was also observed (r = 0.391, P < 0.001). Multiple linear regression analysis revealed that the location, size, and TAI of the calculi were related to the TEL, and the location and size were statistically significant predictors (adjusted r2 = 0.498, P < 0.001). A mathematical model correlating the combination of ultrasonography and NCHCT with TEL was established; this model may provide a foundation to guide the use of energy in Holmium laser lithotripsy. The TEL can be estimated by the location, size, and TAI of the calculus. PMID:27930563

Chronic liver disease (CLD) is associated with the destruction of liver parenchyma cell. It is the main cause of morbidity and mortality in most of the developed countries. Oxidative stress and altered levels of different trace elements in serum have been documented for different diseases including inflammation and many liver diseases. This study aims to evaluate the serum level of malondialdehyde (MDA), nitric oxide (NO), antioxidant vitamin C, C-reactive protein (CRP), and zinc (Zn) in CLD patients and to establish a correlation among the study parameters with the severity of inflammatory conditions of CLD. In this study, CLD patients and healthy volunteers were recruited. Total cholesterol and triglyceride were determined by colorimeter using enzymatic method. Serum non-enzymatic antioxidant vitamin C, reactive oxygen species nitric oxide (NO), and malondialdehyde (MDA) were determined by UV-spectrophotometric method. Trace element (Zn) levels were determined by graphite furnace atomic absorption spectroscopy. Independent sample t test and Pearson's correlation test were performed for statistical analysis using the statistical software package SPSS, Version 20. Studies showed that the MDA (p < 0.001), NO (p < 0.001), and CRP levels were significantly higher in CLD patients than in control subjects. The antioxidant vitamin C (p < 0.001) and trace element zinc (p < 0.001) were comparatively lower in the CLD patients than in control subjects. Elemental Zn showed an inverse relationship with MDA, NO, and CRP but positively correlated with antioxidant capacity, whereas MDA showed a positive correlation with CRP level. Thus, we conclude that attenuated level of Zn and antioxidant in serum play an important role in the inflammatory status of CLD patients by elevating the concentration of MDA, NO, and CRP.

Objective Behçet’s disease (BD), a chronic multisystem inflammatory disorder, is mainly characterized by relapsing periods of a wide range of clinical symptoms. Several cytokine genes may play important roles in the pathogenesis of BD. Therefore, interleukin-1 receptor antagonist (IL-1Ra) gene 86bp variable number tandem repeat (VNTR) variant was investigated in patients with BD in a Turkish population. Methods One hundred nine patients (60 females, 49 males; the mean age±standard deviation [SD] was 36.56±9.571 years) with BD and one hundred healthy individuals (54 females, 46 males; the mean age±SD was 36.64±2.294 years) were examined in the study. For genotyping, polymerase chain reaction-restriction fragment length polymorphism analysis was employed. Data were analyzed using Statistical Package for Social Sciences (SPSS) 22.0 (IBM Corp.; Armonk, NY, USA) (p<0.05) Results The genotype distribution and allele frequencies of the IL-1Ra VNTR variant did not differ significantly between the patients and the controls (p>0.05). The frequency of the a1/a1, a1/a2 genotypes and a1, a2 alleles were the most common both in patients and healthy controls (p=0.37, p=0.26, and p=0.53, respectively). Also, no statistically significant difference was found between the IL-1Ra VNTR variant genotypes and clinical characteristics (p>0.05). Conclusion The results of this study do not support an association between the IL-1Ra VNTR variant and the risk of BD in a Turkish population. However, further studies of this variant with larger sample sizes and different ethnicities are required for confirmation. PMID:29657871

Context: Musculoskeletal pain is common among tea leaf pluckers and is attributed to the load they carry, long working hours, the terrain, and insufficient job rotations. As a result of this, their health and work capacity are affected. Aims: To assess the prevalence, patterns, and factors associated with work-related musculoskeletal disorders (WRMDs) among pluckers in a tea plantation in Annamalai, Tamil Nadu, India. Settings and Design: This cross-sectional study surveyed 195 pluckers selected by simple random sampling aged between 18 years and 60 years. Materials and Methods: The interview schedule had four parts––sociodemographic detail, Standard Nordic Scale, numeric and facial pain rating tool, and a tool to assess factors associated with WRMDs. Statistical Analysis Used: Statistical Package for the Social Sciences (SPSS) version 16. Results: Prevalence of musculoskeletal pain in the last 12 months and the last 7 days was 83.6% and 78.5%, respectively. The most common site for last 1 year was shoulder (59%) and for last 7 days was the lower back (52.8%). Independent t-test revealed that the mean age of those with pain was 6.59 year more and mean years of employment was 1.38 years more among the workers with pain compared to workers without pain. Increasing morbidities among workers was also significantly associated with an increase in WRMDs on Chi-square test. Conclusions: The prevalence of musculoskeletal pain was high among tea pluckers and the most common site during the last 12 months and the last 7 days was the shoulder and lower back respectively was mild in character. Increase in age and duration of employment was associated with WRMDs. PMID:26957816

Background Findings of most studies indicate that the only way to control diabetes and prevent its debilitating effects is through the continuous performance of self-care behaviors. Physical activity is a non-pharmacological method of diabetes treatment and because of its positive effects on diabetic patients, it is being increasingly considered by researchers and practitioners. This study aimed at determining factors influencing physical activity among diabetic women in Iran, using the extended theory of reasoned action in Iran. Methods A sample of 352 women with type 2 diabetes, referring to a Diabetes Clinic in Khoy, Iran, participated in the study. Appropriate instruments were designed to measure the desired variables (knowledge of diabetes, personal beliefs, subjective norms, perceived self-efficacy, behavioral intention and physical activity behavior). The reliability and validity of the instruments were examined and approved. Statistical analyses of the study were conducted by inferential statistical techniques (independent t-test, correlations and regressions) using the SPSS package. Results The findings of this investigation indicated that among the constructs of the model, self efficacy was the strongest predictor of intentions among women with type 2 diabetes and both directly and indirectly affected physical activity. In addition to self efficacy, diabetic patients' physical activity also was influenced by other variables of the model and sociodemographic factors. Conclusion Our findings suggest that the high ability of the theory of reasoned action extended by self-efficacy in forecasting and explaining physical activity can be a base for educational intervention. Educational interventions based on the proposed model are necessary for improving diabetics' physical activity behavior and controlling disease. PMID:22111043

Despite the growing body of literature, the reality of getting evidence into practice remains problematic. The purpose of this study was to establish levels of research awareness amongst registered health care professionals (RHCPs) and the influence of research awareness on evidence-based practice activities. This was a descriptive quantitative study. A convenience sample of 2,126 registered RHCPs working in a large acute hospital in Northeast England, the United Kingdom was used. A self-completion Research Awareness Questionnaire (RAQ) was directed towards measuring RHCP: attitudes towards research, understanding of research and the research process, and associations with practising using an evidence base. Data were entered into a Statistical Package for Social Science (SPSS) database and descriptive and inferential statistics were used. A total of 843 questionnaires were returned. Seven hundred and thirty-three (91%) RHCPs overwhelmingly agreed with the principle that evidence-based practice has a large part to play in improving patient care. This point was reinforced by 86% (n = 701) of respondents strongly agreeing or agreeing with the idea that evidence-based practice is the way forward to change clinical practice. Significant associations were noted between levels of confidence to undertake a piece of research and whether the individual had received adequate information about the research process, had basic knowledge and understanding of the research process, or had research awareness education or training. The study shows that RHCPs, regardless of position or grade, have a positive attitude towards research but face many obstacles. The key obstacles are lack of time, support, knowledge, and confidence. To address these obstacles, it is imperative that the organisation adopts a structured and coordinated approach to enable and empower individuals to practice using an evidence base.

Purpose The purpose of this paper is to examine whether healthcare leaders use evidence-based management (EBMgt) when facing major decisions and what types of evidence healthcare administrators consult during their decision-making. This study also intends to identify any relationship that might exist among adoption of EBMgt in healthcare management, attitudes towards EBMgt, demographic characteristics and organizational characteristics. Design/methodology/approach A cross-sectional study was conducted among US healthcare leaders. Spearman's correlation and logistic regression were performed using the Statistical Package for the Social Sciences (SPSS) 23.0. Findings One hundred and fifty-four healthcare leaders completed the survey. The study results indicated that 90 per cent of the participants self-reported having used an EBMgt approach for decision-making. Professional experiences (87 per cent), organizational data (84 per cent) and stakeholders' values (63 per cent) were the top three types of evidence consulted daily and weekly for decision-making. Case study (75 per cent) and scientific research findings (75 per cent) were the top two types of evidence consulted monthly or less than once a month. An exploratory, stepwise logistic regression model correctly classified 75.3 per cent of all observations for a dichotomous "use of EBMgt" response variable using three independent variables: attitude towards EBMgt, number of employees in the organization and the job position. Spearman's correlation indicated statistically significant relationships between healthcare leaders' use of EBMgt and healthcare organization bed size ( r s = 0.217, n = 152, p < 0.01), attitude towards EBMgt ( r s = 0.517, n = 152, p < 0.01), and the number of organization employees ( r s = 0.195, n = 152, p = 0.016). Originality/value This study generated new research findings on the practice of EBMgt in US healthcare administration decision-making.

Riyadh and central province falls in a moderate prevalent zone of hemoglobinopathies in Saudi Arabia. However, it has been observed that the physicians working in Saudi Arabia invariably advise all cases of anemia for hemoglobin electrophoresis (HE). The present work was carried out to study the yield of the HE in Riyadh and the investigative practices of the physicians advising HE. The study was carried out in the hospitals of King Saud University from 2009 to 2011 in order to assess the yield of HE in referred cases of clinical anemia. A total of 1073 cases divided in two groups of males and females had undergone complete blood count and red blood cell morphology. Cellulose acetate HE was performed and all the positive results were reconfirmed on the high performance liquid chromatography (HPLC). The results were analyzed for the type of hemoglobinopathies. For statistical analysis Statistical Package for Social Sciences 15 version (SPSS Inc., Chicago, IL, USA) was used. A total of 405 males and 668 females blood samples were included in the present study. 116 (28.5%) males and 167 (25%) females showed an abnormal pattern on HE. The incidence of beta thalassemia trait was higher in females while sickle cell trait was predominantly seen in males. Red cell indices were reduced considerably in thalassemias, but were unaffected in sickle cell disorders, except those which had concurrent alpha trait. The total yield of HE was 26.6% which was much less than expected. The physicians are advised to rule out iron deficiency and other common causes of anemia before investigating the cases for hemoglobinopathies, which employs time consuming and expensive tests of HE and HPLC.

Quality of tuberculosis (TB) microscopy diagnosis is not a guarantee despite implementation of External Quality Assurance (EQA) service in all laboratories of health facilities. Hence, we aimed at evaluating the technical quality and the findings of sputum smear microscopy for acid fast bacilli (AFB) at health centers in Hararge Zone, Oromia Region, Ethiopia. A cross-sectional study was carried out between July 8, 2014 and July 7, 2015.A pre-tested structured questionnaire was used to collect data. Lot Quality Assurance Sampling (LQAS) method was put into practice for collecting all necessary sample slides. Data were analyzed by using SPSS (Statistical Package for Social Sciences) version 20 software. P-value < 0.05 was considered as statistically significant. Of the total55 health center laboratories which had been assessed during the study period, 20 (36.4%) had major technical errors; 13 (23.6%) had 15 false negative results and 17 (30.9%) had 22 false positive results. Moreover, poor specimen quality, smear size, smear thickness, staining and evenness were indicated in 40 (72.7%), 39 (70.9%), 37 (67.3%), 27(49.1%) and 37 (67.3%) of the collected samples, respectively. False negative AFB findings were significantly associated with lack of Internal Quality Control (IQC) measures (AOR (Adjusted Odds Ratio): 2.90 (95% CI (Confidence Interval): 1.25,6.75) and poor staining procedures (AOR: 2.16(95% CI: 1.01, 5.11). The qualities of AFB smear microscopy reading and smearing were low in most of the laboratories of the health centers. Therefore, it is essential to strength EQA program through building the capacity of laboratory professionals.

The future health of individuals depends on the well being of the children of today. Proper nutrition for children is very important. The most commonly used index of obesity and over weight is Body Mass Index. The growth of children should be monitored using the Body Mass Index (BMI) and risk factors assessed through a dietary and physical activity history. The increase in obesity is attributed to increased carbohydrate consumption among children. Obesity and caries are both diet-based conditions that share a cause that is, excessive ingestion of fermentable carbohydrates. This study was undertaken to determine the association of nutritional status with dental caries in 8 to 12 year old children of Udaipur city. The present study was conducted on a random sample of 1000 boys and girls, aged 8-12 years. The children were selected from schools located in the Udaipur City, Rajasthan. The schools examined were of government and private sector schools in Udaipur city. The children from schools of Udaipur city was taken in the study with male, female and age group ratio as per distribution in population. A proforma was used to record children's age, gender, school, year, height, weight, parental income and dental caries status. Statistical analysis was done using Statistical Package of Social Science (SPSS Version 15; Chicago Inc., USA). It was found that caries free individuals were more from normal nutritional status group with 134 (13.4 %) subjects where as only 11 (1.1 %) of subjects obese children were found caries free. Study shows that the children with normal BMI for age had more caries in their primary teeth, as well as in their permanent teeth, than the overweight children.

Background: The psychological stress after diagnosis of breast cancer is often severe. Most of the women with breast cancer and their families suffer from emotional, social, financial and psychological disturbances. Materials and Methods: A cluster non-randomized trial was conducted at a Cancer Society in Melaka, Malaysia to assess the effectiveness of psycho-education on well-being status and depression among breast cancer patients. The study period was for one month (11th June 2011 and 16th July 2011). Participants in this study were 34 adult women suffering from non-metastatic breast cancer and on appropriate allopathic medication. The WHO-five Well-being Index (1998 version) was used as the screening instrument for the assessment of well-being and depression. The data collected were tabulated and analyzed by using the Statistical Package for Social Sciences (SPSS) version 11.0. Wilcoxon Signed-rank Test was applied for comparison between pre-test and post-test scores. A P value <0.05 was considered as statistically significant. Results: This study revealed that majority of the participants was in the state of adequate well-being after the psycho-education 33 (97.1%). The proportion of depressed individuals had also reduced from 8 (23.5%) to 1 (2.9%) after the psychological intervention. The post-test results significantly improved after the intervention for the items related to “I have felt calm and relaxed”, “I woke up feeling fresh and rested” and “my daily life has been filled with things that interest me” along with the “overall impression” in the WHO-5 Well-being Index. Conclusion: Group psycho-education played a significant role in improving the well-being status and reducing depression of breast cancer survivors. PMID:23766593

Context: Bilateral pediatric cataracts are important cause of visual impairment in children. Aim: To study the outcome of bilateral pediatric cataract surgery in young children. Setting and Design: Retrospective case series in a tertiary center. Materials and Methods: Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. Statistical Methods: Independent sample t-test, Fisher's exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA) version 12. Results: 215/257 (83.7%) patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months). Congenital cataract was present in 107 patients (58.2%) and developmental cataract in 77 patients (41.8%). The mean age at surgery was 55.2 months (range: 1-168 months). Out of 430 eyes, 269 (62.6%) had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months). Pre-operatively, 102 patients (47.3%) had visual acuity <6/60, in the better eye, compared to 37 patients (17.2%) post-operatively (P < 0.001). Eighty-five patients (39.5%) had visual acuity >6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3%) and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%). The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5) and total cataract (OR: 4.8; 95% CI, 1.3-17).

Background: There is little information available in the literature concerning the contribution of dementia in injury deaths in elderly people (≥60 years). Aim: This study was intended to investigate the extent of dementia-related pathologies in the brains of elderly people who died in traffic accidents or by suicide and to compare our findings with age- and sex-matched natural deaths in an elderly population. Materials and Methods: Autopsy-derived human brain samples from nine injury death victims (5 suicide and 4 traffic accidents) and nine age- and sex-matched natural death victims were screened for neurodegenerative and cerebrovascular pathologies using histopathological and immunohistochemical techniques. For the analysis, Statistical Package for the Social Sciences (SPSS) version 16.0 was used. Results: There was a greater likelihood for Alzheimer's disease (AD)-related changes in the elders who succumbed to traffic accidents (1 out of 4) compared to age- and sex-matched suicides (0 out of 5) or natural deaths (0 out of 9) as assessed by the National Institute on Aging – Alzheimer's Association guidelines. Actual burden of both neurofibrillary tangles (NFTs) and (SPs) was comparatively higher in the brains of traffic accidents, and the mean NFT counts were significantly higher in the region of entorhinal cortex (P < 0.05). However, associations obtained for other dementia-related pathologies were not statistically important. Conclusion: Our findings suggest that early Alzheimer stages may be a contributing factor to injury deaths caused by traffic accidents in elderly people whereas suicidal brain neuropathologies resembled natural deaths.

An analysis of K--5 teachers' beliefs regarding the uses of direct instruction, the discovery method, and the inquiry method in elementary science education

NASA Astrophysics Data System (ADS)

Kowalczyk, Donna Lee

The purpose of this study was to examine K--5 elementary teachers' reported beliefs about the use, function, and importance of Direct Instruction, the Discovery Method, and the Inquiry Method in the instruction of science in their classrooms. Eighty-two teachers completed questionnaires about their beliefs, opinions, uses, and ideas about each of the three instructional methods. Data were collected and analyzed using the Statistical Package of the Social Sciences (SPSS). Descriptive statistics and Chi-Square analyses indicated that the majority of teachers reported using all three methods to varying degrees in their classrooms. Guided Discovery was reported by the teachers as being the most frequently used method to teach science, while Pure Discovery was reportedly used the least frequently. The majority of teachers expressed the belief that a blend of all three instructional methods is the most effective strategy for teaching science at the elementary level. The teachers also reported a moderate level of confidence in teaching science. Students' ability levels, learning styles, and time/class schedule were identified as factors that most influence teachers' instructional choice. Student participation in hands-on activities, creative thinking ability, and developing an understanding of scientific concepts were reported as the learning behaviors most associated with student success in science. Data obtained from this study provide information about the nature and uses of Direct Instruction, the Discovery Method, and the Inquiry Method and teachers' perceptions and beliefs about each method's use in science education. Learning more about the science teaching and learning environment may help teachers, administrators, curriculum developers, and researchers gain greater insights about student learning, instructional effectiveness, and science curriculum development at the elementary level.

Bacterial vaginosis (BV) is a polymicrobial, superficial vaginal infection involving a reduction in the amount of hydrogen peroxide-producing Lactobacillus and overgrowth of anaerobic bacteria. Common symptoms include increased fishy smelling vaginal discharge which is usually white or gray in color. Burning with urination may occur and itching is uncommon. Risk factors include douching, new or multiple sex partners, antibiotics, and use of intrauterine device among others. This cross-sectional study assessed the prevalence of bacterial vaginosis among sexually active women aged 15-45 years. Vaginal swabs were obtained with the use of sterile swab sticks which were later smeared on clean glass slides and then Gram stained. The stained smears were observed for bacterial morphotypes with the X100 oil immersion objective and the Nugent scoring system was used to determine BV. Data were analyzed using the Statistical Package for Social Scientists (SPSS) version 17.0 and were considered significant at p < 0.05. A total of 100 women participated in the study with the overall prevalence of BV rated 38%. The prevalence of BV with respect to associated factors was also investigated and it was observed that BV was more prevalent in the age groups 20-25 (48.1%) and 25-29 (44.4%), those who had attained only primary education (60.5%), married women, (68.4%), pregnant women (71.0%), and women who practiced vaginal douching, (97.4%). However, no statistical significant difference was observed in the prevalence between these parameters (P > 0.05). Conclusively, the prevalence of bacterial vaginosis in our study population is 38% and highest among women aged between 25 and 34 years, pregnant women, married women, less educated women and women who practiced poor vaginal hygiene.

To longitudinally assess the quality of life in maxillectomy patients rehabilitated with obturator prosthesis. Thirty-six subjects were enrolled in the span of 16 months, out of which six were dropouts. Subjects (age group 20-60 years) with maxillary defects, irrespective of the cause, planned for definite obturator prosthesis, were recruited. The Hindi version of European Organization for Research and Treatment of Cancer, Head and Neck version 1 of Quality of Life Questionnaire was used before surgical intervention and one month after definitive obturator. Questionnaire includes 35 questions related to the patient's physical health, well being, psychological status, social relation and environmental conditions. The data were processed with statistical package for social science (SPSS). Probability level of P<.05 was considered statistically significant. The quality of life after rehabilitation with obturator prosthesis was 81.48% (±13.64) on average. On item-level, maximum mean scores were obtained for items problem with teeth (1.87 ± 0.94), pain in mouth (1.80 ± 0.92), trouble in eating (1.70 ± 0.88), trouble in talking to other people (1.60 ± 1.22), problems in swallowing solid food (1.57 ± 1.22) and bothering appearance (1.53 ± 1.04); while minimum scores were obtained for the items coughing (1.17 ± 0.38), hoarseness of voice (1.17 ± 0.53), painful throat (1.13 ± 0.43), trouble in having social contacts with friends (1.10 ± 0.40) and trouble having physical contacts with family or friends (1.10 ± 0.31). Obturator prosthesis is a highly positive and non-invasive approach to improve the quality of life of patients with maxillectomy defects.

To determine whether fetuses affected by either chromosomal abnormalities or central nervous system (CNS) malformations are prone to complications during pregnancy and delivery. In this study, 320 singleton pregnancies with CNS malformations and 133 singleton pregnancies with chromosomal abnormaLities were compared with 149,112 singleton births without any known congenital anomalies. Exclusion criteria were: births with other congenital anomalies or malformations, pregnancies Lacking prenatal care and multiple pregnancies. Data was obtained using the computerized birth discharge records. The statistical analysis was performed with the SPSS package. There were no statistically significant differences in maternal age, ethnicity, uterine anomalies or parity. The ratio of general anesthesia was almost double in the study groups compared to the control group: 25% in the CNS malformation group (RR 2.617, CI 2.031-3.372) and 25.6% in the chromosomal abnormality group (RR 2.696, CI 1.825-3.982) and 11.3% in the control group (p < 0.001). There were nearly double cesarean sections (CS) rates in both study groups: 21.5% in the CNS malformation group, 20.3% in the chromosomal abnormaLity group and 12% in the control group. A logistic regression model that included previous CS, maLpresentation, non-reassuring fetal heart monitor (NRFHR) and presence of a malformation, concluded that the presence of a malformation was not an independent risk factor for CS. However, indirect causes, such as malpresentation (4.34 OR), were independently associated with the malformations. Fetuses affected by either CNS malformations or chromosomal abnormalities have a higher rate of pregnancy and delivery complications, including those which increase the risk of maternal morbidity and mortality.

Context: Only a few methods have been published dealing with the visualization of heat-induced cracks inside bones and teeth. Aims: As a novel approach this study used nondestructive X-ray microtomography (micro-CT) for volume analysis of heat-induced cracks to observe the reaction of human molars to various levels of thermal stress. Materials and Methods: Eighteen clinically extracted third molars were rehydrated and burned under controlled temperatures (400, 650, and 800°C) using an electric furnace adjusted with a 25°C increase/min. The subsequent high-resolution scans (voxel-size 17.7 μm) were made with a compact micro-CT scanner (SkyScan 1174). In total, 14 scans were automatically segmented with Definiens XD Developer 1.2 and three-dimensional (3D) models were computed with Visage Imaging Amira 5.2.2. The results of the automated segmentation were analyzed with an analysis of variance (ANOVA) and uncorrected post hoc least significant difference (LSD) tests using Statistical Package for Social Sciences (SPSS) 17. A probability level of P < 0.05 was used as an index of statistical significance. Results: A temperature-dependent increase of heat-induced cracks was observed between the three temperature groups (P < 0.05, ANOVA post hoc LSD). In addition, the distributions and shape of the heat-induced changes could be classified using the computed 3D models. Conclusion: The macroscopic heat-induced changes observed in this preliminary study correspond with previous observations of unrestored human teeth, yet the current observations also take into account the entire microscopic 3D expansions of heat-induced cracks within the dental hard tissues. Using the same experimental conditions proposed in the literature, this study confirms previous results, adds new observations, and offers new perspectives in the investigation of forensic evidence.

Background: The pathogenesis of development and progression of neurosensory retinal detachment (NSD) in diabetic macular edema (DME) is not yet fully understood. The purpose of this study is to describe the spectral domain optical coherence tomography (SD-OCT) morphological characteristics of NSD associated with DME in the form of outer retinal communications and to assess the correlation between the size of communications and various factors. Materials and Methods: This was an observational retrospective nonconsecutive case series in a tertiary care eye institute. We imaged NSD and outer retinal communications in 17 eyes of 16 patients having NSD associated with DME using SD-OCT. We measured manually the size of the outer openings of these communications and studied its correlation with various factors. Statistical analysis (correlation test) was performed using the Statistical Package for Social Sciences (SPSS) software (version 14.0). The main outcome measures were correlation of the size of communications with dimensions of NSD, presence of subretinal hyper-reflective dots, and best-corrected visual acuity (BCVA). Results: The communications were seen as focal defects of the outer layers of elevated retina. With increasing size of communication, there was increase in height of NSD (r = 0.701, P = 0.002), horizontal diameter of NSD (r = 0.695, P = 0.002), and the number of hyper-reflective dots in the subretinal space (r = 0.729, P = 0.002). The minimum angle of resolution (logMAR) BCVA increased with the increasing size of communications (r = 0.827, P < 0.0001). Conclusions: Outer retinal communications between intra and subretinal space were noted in eyes having NSD associated with DME. The size of communications correlated positively with the size of NSD and subretinal detachment space hyper-reflective dots, and inversely with BCVA. PMID:24379554

Preeclampsia is a major pregnancy complication without curative treatment available. A Norwegian Preeclampsia Family Cohort was established to provide a new resource for genetic and molecular studies aiming to improve the understanding of the complex pathophysiology of preeclampsia. Participants were recruited from five Norwegian hospitals after diagnoses of preeclampsia registered in the Medical birth registry of Norway were verified according to the study's inclusion criteria. Detailed obstetric information and information on personal and family disease history focusing on cardiovascular health was collected. At attendance anthropometric measurements were registered and blood samples were drawn. The software package SPSS 19.0 for Windows was used to compute descriptive statistics such as mean and SD. P-values were computed based on t-test statistics for normally distributed variables. Nonparametrical methods (chi square) were used for categorical variables. A cohort consisting of 496 participants (355 females and 141 males) representing 137 families with increased occurrence of preeclampsia has been established, and blood samples are available for 477 participants. Descriptive analyses showed that about 60% of the index women's pregnancies with birth data registered were preeclamptic according to modern diagnosis criteria. We also found that about 41% of the index women experienced more than one preeclamptic pregnancy. In addition, the descriptive analyses confirmed that preeclamptic pregnancies are more often accompanied with delivery complications. The data and biological samples collected in this Norwegian Preeclampsia Family Cohort will provide an important basis for future research. Identification of preeclampsia susceptibility genes and new biomarkers may contribute to more efficient strategies to identify mothers "at risk" and contribute to development of novel preventative therapies.

To analyse the feasibility of laparoscopic radical nephrectomy (LRN) for renal tumours> 7 cm and to compare the operative and oncologic outcomes with open radical nephrectomy (ORN). This was a prospective, observational, comparative study. The study was conducted at a tertiary care super-speciality hospital. All the patients who underwent radical nephrectomy for> 7 cm renal tumours during a period of 2 years (April 2012 to May 2014) were included in the study. Thirty patients were included in each ORN and LRN group. Pre-operative, intra-operative and post-operative data for all these patients were collected and analysed. Statistical Package for the Social Sciences (SPSS, version 11.0 for Windows, Chicago, IL). Mean age of patients in ORN and LRN groups was 57.3 ± 6.1 years and 54.9 ± 5.7 years, respectively (P = 0.220). As compared to ORN, LRN had less drop in post-operative haemoglobin (1.39 ± 0.55 g/dl vs. 4.07 ± 1.023 g/dl, P < 0.05), less drop in haematocrit value (4.7 ± 3.25% vs. 9.5 ± 5.13%, P < 0.05), less analgesic requirement for tramadol hydrochloride (165 ± 74.5 mg vs. 260 ± 181.66 mg) and less mean hospital stay (4.2 days vs. 6.1 days, P < 0.05). There was no statistically significant difference in post-operative complication rate and recurrence-free survival over a median follow-up of 17 months (93.9% - LRN vs. 90% - ORN) Conclusions: LRN for large renal tumours is feasible and achieves oncologic outcomes similar to that obtained with ORN.

The preparedness levels of front-line clinicians including physicians, nurses, emergency medical responders (EMRs), and other medical staff working in clinics, offices and ambulatory care centers must be assessed, so these personnel are able to deal with communicable and potentially lethal diseases, such as severe acute respiratory syndrome (SARS). In order to determine the knowledge of these clinicians, a survey of their understanding of SARS and their use of educational resources was administered. A questionnaire was distributed to physicians, nurses, and EMRs attending conferences on SARS in the summer of 2003. Questions related to information sources, knowledge of SARS, and plans implemented in their workplace to deal with it. Statistical analysis was performed using the Statistical Package for the Social Sciences (10.1 Program, SPSS Inc., Chicago, Illinois). A total of 201 community healthcare providers (HCPs) participated in the study. A total of 51% of the participants correctly identified the incubation period of SARS; 48% correctly identified the symptoms of SARS; and 60% knew the recommended infection control precautions to take for families. There was little difference in knowledge among the physicians, nurses, and EMRs evaluated. Media outlets such as newspapers, journals, television, and radio were reported as the main sources of information on SARS. However, there appears to be a growing use of the Internet, which correlated best with the correct answers on symptoms of SARS. Fewer than one-third of respondents were aware of a protocol for SARS in their workplace. A total of 60% reported that N-95 masks were available in their workplace. These findings suggest the need for more effective means of education and training for front-line clinicians, as well as the institution of policies and procedures in medical offices, clinics, and emergency services in the community.

Propofol has been used for the induction and maintenance of anesthesia. However, patients experience vascular pain during its injection. The objective of this study was to compare the effect of the lipid type used in propofol preparations and that of lidocaine on the immediate and delayed vascular pain induced by propofol administration. In this double-blinded clinical study, 150 patients at American Society of Anesthesiologists level I-II were randomly divided into three equally sized groups. A propofol with medium and long-chain triglycerides (propofol-MCT/LCT) was administered to the first group. The second group received propofol containing propofol-LCT, and the third group received propofol-LCT and pretreatment lidocaine 20 mg. The incidence and the intensity of immediate (during injection) and delayed injection pain (after 20 s) were evaluated on a verbal analog scale (1-10) until patients' unconsciousness. Sample size was calculated with SigmaPlot version 12.5 software. Data were analyzed with Statistical Package for the Social Sciences (SPSS) version 16, one-way analysis of variance, and post-hoc Tukey. P < 0.05 was considered statistically significant. The demographic parameters of the three groups were similar. The lidocaine group experienced the least immediate vascular pain. The intensity of pain was highest in the propofol-LCT group (P = 0.04). Additionally, the intensity of delayed pain was lowest in the propofol-MCT/LCT group (P = 0.01). The incidence of pain associated with the propofol administration was 26.5, 44, and 18%, respectively, in propofol-MCT/LCT, propofol-LCT, and lidocaine and propofol-LCT groups. The results indicate an effect of the lipid type on delayed pain reduction, especially propofol-MCT/LCT. On the other hand, the lidocaine decreases immediate propofol-LCT vascular pain.

Nutritional status is strongly associated with the level of health and quality of life of the population, and is especially relevant in the case of the elderly. The aim was to study the nutritional status in a population of non-institutionalised over 65 year-olds in the city of Badajoz, describing the sociodemographic variables, biochemical parameters, and functional assessment. A descriptive study was performed using a design population, which was randomised and stratified in health centres of the city, with a sample size of 298 patients being obtained. The sociodemographic variables included gender, age, educational level, anthropometric analysis with estimated body mass index, and percentage fat weight. Statistical tests were performed using SPSS v.15 statistical package. The prevalence of overweight and obesity as measured by fat weight was 61.9% (56.1-67.8), with a body mass index of 65.8% (60.2-71.4). It was higher in women, with a fat weight of 67.3% (2.56 to 2.73) and a body mass index of 71.8% (2.64 to 2.78). The nutritional status of the population according to the questionnaire "Know your nutritional health" was rated "good". The most common nutritional problem in the non-institutionalised population over 65 years in the city of Badajoz is obesity, especially in women, and in people with low educational level. This high prevalence suggests that health education on a better lifestyle in this population should be a priority. Copyright © 2016 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Obesity is increasing in developed as well as in developing countries. This analytical cross sectional study was carried out to document the relation between blood pressure, serum creatinine and body mass index in female and to assess potential health differences among obese female and normal weight female. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2012 to June 2013. Seventy female persons volunteered as subjects. Among them 35 were within normal weight (BMI 18.5-24.9kg/m²) and 35 were obese (BMI≥30kg/m²). Non probability purposive type of sampling technique was used to select the subjects. Measurement of body mass index and blood pressure were done as per procedure. Serum creatinine level was estimated by enzymatic colorimetric method. The results were calculated and analyzed by using SPSS (statistical package for social science, version 17.0), scientific electronic calculator and simultaneously with a computer assisted program like Microsoft excel. Unpaired 't' test was applied to find the significance of difference regarding serum creatinine and blood pressure levels in obese female. The value of p was 1% to indicate highly significant and 5% to indicate simply significant or statistically significant. The mean±SE of systolic blood pressure, diastolic blood pressure and serum creatinine levels were 135.71±1.58mmHg, 88.74±0.95mmHg and 1.03±0.01mg/dl respectively; significant at 1% level for obese group of BMI (p<0.0001). The examinations and biochemical investigations revealed that high BMI is significantly related to increased levels of serum creatinine & blood pressure in obese female which indicate the obese subjects are prone to cardiovascular & metabolic risk.

The high turnover of nurses has become a universal issue. The manner in which nurses view their organization’s ethical climate has direct bearing on their job satisfaction. There is little empirical evidence confirming a relationship between different sorts of ethical climate within organizations and job satisfaction in Iran. The aim of this study was to determine the correlation between nurses’ perception of ethical climate and job satisfaction in the Teaching Hospital of Kerman University of Medical Sciences. A descriptive analytical design was used in this study. The sample consisted of 275 nurses working in 4 hospitals affiliated with the Kerman University of Medical Sciences. The instruments used in this study included a demographic questionnaire, Ethical Climate Questionnaire (ECQ), and Job Satisfaction Scale (JS). Data analysis was carried out using Pearson’s correlation, one-way ANOVA, T-test and descriptive statistic through Statistical Package for Social Science (SPSS), version 16. Across the five dimensions of ECQ the highest mean score pertained to professionalism (mean = 13.45±3.68), followed by rules climate (mean = 13.41±4.01), caring climate (mean = 12.92±3.95), independence climate (mean = 11.35±3.88), and instrumental climate (mean = 8.93±2.95). The results showed a positive correlation among ethical climate type of: professionalism (p=0.001), rules (p=0.045), caring (p=0.000), independence (p=0.000) with job satisfaction, and no correlation was found between instrumental climate and job satisfaction. The result of this research indicated a positive correlation among professionalism, caring, rules, independence climate and job satisfaction. Therefore managers of hospitals can promote nurses’ job satisfaction by providing ethics training programs that establish a working team and a culture that strengthens team spirit among nurses.

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.

Although it is generally accepted that paramedics attend unexpected births, there is a paucity of literature about their management of women in labour. This study aimed to investigate the caseload of women in labour attended by a statewide ambulance service in Australia during one year and the management provided by paramedics. Retrospective clinical data collected on-scene by paramedics via in-field electronic patient care records were provided by Ambulance Victoria. Patient case reports were electronically extracted from the Ambulance Victoria's Clinical Data Warehouse via comprehensive filtering followed by manual sorting. Descriptive statistics were analysed using Statistical Package for Social Sciences (SPSS v.19). Over a 12-month period, paramedics were called to 1517 labouring women. Two thirds of women were at full-term gestation, and 40% of pre-term pregnancies were less than 32 weeks gestation. Paramedics documented 630 case reports of women in early labour and a further 767 in established labour. There were 204 women thought to be second stage labour, including 134 who progressed to childbirth under paramedic care. When paramedics assisted with births, the on-scene time was significantly greater than those patients transported in labour. Pain relief was provided significantly more often to women in established labour than in early labour. Oxygen was given to significantly more women in preterm labour. While paramedics performed a range of procedures including intravenous cannulation, administration of analgesia and oxygen, most women required minimal intervention. Paramedics needed to manage numerous obstetric and medical complications during their management. Paramedics provide emergency care and transportation for women in labour. Most of the women were documented to be at term gestation with minimal complications. To enable appropriate decision making about management and transportation, paramedics require a range of clinical assessment skills comprising essential knowledge about antenatal and intrapartum care.

There is a relative paucity of high-level evidence that guides the treatment of displaced midshaft clavicle fractures in adolescents. Some use overhead sports or significant shortening as relative indications for surgical treatment, while others rarely consider operative intervention for these patients. The purpose of this study is to determine the effect of overhead sports participation and fracture shortening on subjective and objective outcomes after nonoperative treatment of displaced midshaft clavicle fractures in those aged 10-17 years. Using a radiographic database, adolescents with displaced clavicle fractures were identified and contacted over the phone. These subjects were invited to take part in the study in return for compensation. Radiographic measurements of dedicated clavicle films around the time of injury were performed, and a custom survey aimed at elucidating participation in overhead or contact sports was given. The Nottingham Clavicle Score (NCS) and the Constant Shoulder Score were obtained for each patient to provide both subjective and objective outcome data. Statistical Package for Social Science (SPSS) software (version 22, IBM) was used to compare radiographic and sports data to the outcome measures. Gender, age at the time of fracture, time since fracture, relative and absolute radiographic shortening, and hand dominance were all not significantly correlated with subjective or objective outcomes. Five patients (23%) reported not feeling happy with the appearance of their shoulder at the beach or at the pool. This group had statistically lower NCS results. Eleven of 22 participated in ≥6 months per year of overhead or contact sports; they did not have worse subjective or objective outcomes. Fracture shortening and sports participation do not have a significant impact in adolescents on outcomes after displaced midshaft clavicle fracture. Copyright © 2015 Elsevier Ltd.

To investigate the prevalence of metabolic syndrome (MetS) in young Chinese population and assess the association between HOMA-IR and different components of MetS in young Chinese men. Overall 5576 young Chinese subjects (age range [19-44 yr], 3636 men) were enrolled in, who visited our Health Care Center for a related health checkup from March to December 2008. The international diabetes federation (IDF) definition for MetS was used. The SPSS statistical package, version 11.5 was used for the statistical analysis. The prevalence of MetS was 21.81% in young men and 5.62% in young women. According to suffering from different numbers of MetS components, the male subjects were divided into four groups. Numbers of MetS components were more and HOMA-IR values were significantly higher. In this male population, the quartile of HOMA-IR was higher, values of triglyceride (TG), fasting plasma glucose (FBG), systolic blood pressure(SBP), diastolic blood pressure(DBP) and waist circumference (WC) were all significantly higher, as well as high density lipoprotein cholesterol (HDL-C) value was significantly lower (P= 0.000). In Spearman's correlation analysis, HOMA-IR was positively correlated with TG, FBG, SBP, DBP and WC, and negatively correlated with HDL-C (r= 0.460, 0.464, 0.362, 0.346, 0.586, -0.357, respectively, all P value= 0.000). The prevalence of MetS in these young Chinese men was obviously high. Insulin resistance played an important role in occurrence and development of MetS. Waist circumference was the best correlation with HOMA-IR among all components of MetS.

Literature suggests that glottic view is better when using McGrath(®) Video laryngoscope and Truview(®) in comparison with McIntosh blade. The purpose of this study was to evaluate the effectiveness of McGrath Video laryngoscope in comparison with Truview laryngoscope for tracheal intubation in patients with simulated cervical spine injury using manual in-line stabilisation. This prospective randomised study was undertaken in operation theatre of a tertiary referral centre after approval from the Institutional Review Board. A total of 100 consenting patients presenting for elective surgery requiring tracheal intubation were randomly assigned to undergo intubation using McGrath(®) Video laryngoscope (n = 50) or Truview(®) (n = 50) laryngoscope. In all patients, we applied manual-in-line stabilisation of the cervical spine throughout the airway management. Statistical testing was conducted with the statistical package for the social science system version SPSS 17.0. Demographic data, airway assessment and haemodynamics were compared using the Chi-square test. A P < 0.05 was considered significant. The time to successful intubation was less with McGrath video laryngoscope when compared to Truview (30.02 s vs. 38.72 s). However, there was no significant difference between laryngoscopic views obtained in both groups. The number of second intubation attempts required and incidence of complications were negligible with both devices. Success rate of intubation with both devices was 100%. Intubation with McGrath Video laryngoscope caused lesser alterations in haemodynamics. Both laryngoscopes are reliable in case of simulated cervical spine injury using manual-in-line stabilisation with 100% success rate and good glottic view.

Prenatal depression (PND) is a common psychiatric disorder in pregnant women and leads to psychosocial dysfunction, high suicidal rate, and adverse childcare. Patients with PND have omega-3 polyunsaturated fatty acid (omega-3 or n-3 PUFAs) deficits, which might link to chronic low-grade inflammatory process and the pathophysiological mechanisms of depression. In this case-control study, we examined the levels of PUFAs and inflammatory cytokines in PND. Blood samples were obtained and analyzed from 16 healthy controls and 17 depressed cases (PND group) diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Independent sample t-test and correlation analysis were performed with Statistical Package for the Social Sciences (SPSS) logistics correlation analysis. PND group had significantly lower levels of total n-3 (p=0.026), docosahexaenoic acid (DHA) (p=0.020) and eicosapentaenoic (EPA) (p=0.019) but a higher omega-6 (n-6)/n-3 PUFAs ratio (p=0.007) and tumor necrosis factor alpha (TNF-α) (p=0.016) level. Moreover, the duration of current PND episodes were also significantly correlated with DHA, EPA, n-3 PUFAs, n-6/n-3 ratio and TNF-α. In terms of PUFAs and cytokine levels, only DHA was inversely correlated with TNF-α. PND is significantly associated with lower DHA, EPA, and total n-3 PUFAs levels and an increased n-6/n-3 PUFAs ratio, while the duration of PND is associated with lower levels of n-3 PUFAs, including DHA and EPA. The correlation of PUFAs levels with depression and TNF-α level grant further investigation into the inflammatory process underlying PND, mediated by PUFAs. Copyright © 2017 Elsevier Inc.

Clinical practice guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances. Despite abundance of asthma guidelines, prevalence has continued to increase globally. There is need to assess how the contents of asthma guidelines are put to clinical use by doctors in the management of children with asthma. This study aims at evaluating the clinical practice of paediatric residents in applying GINA guidelines. Cross-sectional descriptive study of paediatric residents from 23 university teaching hospitals in Nigeria using structured questionnaire. Data analyses were with Statistical Package for Social Sciences (SPSS) version 19 (Chicago IL). Chi square was used to assess for any significant associations between categorical variables. A p < 0.05 was regarded to be statistically significant. Sixty-six paediatric residents aged 27- 40 years were enrolled into the study (37 females and 29 males). One-third had spent more than three years in residency training. Fifty-eight residents (87.9%) were aware of the GINA guidelines while 46 (69.7%) were familiar with its contents. Only 39 (59.1%) residents adhered to the GINA guidelines. Twenty of the 35 junior residents (57.1%) compared to 26 of 31 (83.9%) senior residents were familiar with the GINA guidelines (p=0.031) while 15 of 35 junior residents (42.9%) compared to 24 of 31 senior residents (77.4%) consistently follow the GINA guidelines (p=0.006). Adherence to GINA guidelines was not influenced significantly by years of graduation or training (p>0.05). The use of the GINA guidelines was poor among paediatric residents. Application of contents rather than just availability of asthma guidelines may partly account for increasing asthma prevalence globally.

The aim of the study was to investigate the physician and nursing perceptions regarding communication and collaboration as well as the factors that may influence these activities. A self-administered questionnaire survey was sent to a random sample of 93 physicians and 197 nurses based in two large public hospitals in Athens, Greece. Descriptive statistics, t-test and chi square test were performed with the SPSS 19.0 statistical package. Years of experience, the size of the clinic, the university degree and the postgraduate studies were found to be significant factors according to nurses' view (p < 0.05). For the physicians, age, sex, years of experience and the size of clinic affected the communication and collaboration with the nursing staff significantly (p < 0.05). In summary, these findings suggest that nurses and physicians do not share the same views concerning the effectiveness of their communication and nurses' role in the decision-making process of the patients' care. The most important barrier for the establishment of good relations between these professions, according to the physicians, was that they did not recognize the nurses' professional role. The study also indicated that the absence of interprofessional collaboration may result in a higher possibility of errors and omissions in patients' care. Therefore, in everyday practice, both nurses and physicians should acknowledge the importance of their effective communication and they should develop and implement interprofessional teamwork interventions to improve collaboration. Moreover, nurses have to constantly consolidate their role in the decision process and patients' care, especially in countries with limited interprofessional collaboration culture. In addition, factors that improve physicians' attitudes toward collaboration and effective communication should be further explored.

ABSTRACT Objective: To determine the progression of pigment dispersion syndrome (PDS) into pigmentary glaucoma (PG) in a population at the Central Military Hospital in Bogotá, Colombia. Materials and methods: A retrospective study was conducted, based on a review of medical records of patients with PDS evaluated in the Glaucoma Clinic. Data were collected in a database in excel and subsequently analyzed with the software Statistical Package for the Social Sciences (SPSS), performing Chi-square test analysis and Spearman’s rho test. Results: Forty-eight eyes of 24 patients were included. Forty-two percent were women and 58% were men. Pigmentation of the trabecular meshwork was the most frequent clinical sign (100%), followed by Krukenberg’s spindle (91.7%), the least frequent were the iris concavity and iris heterochromia (4.2%), the average of the spherical equivalent was of - 1.33 (SD 2.07). The rate of conversion of PDS to PG was 37.5%, after an average follow-up of 50.7 months. Having an intraocular pressure (IOP) greater than 21 mm Hg was statistically the only significant risk factor for conversion. Conclusion: We found several differences in frequency and clinical signs in these patients in contrast to previous data, probably due to different racial characteristics. The rate of progression is similar to previous reports despite of heterogeneity of these. Having IOP > 21 mm Hg was the only risk factor associated with progression in this sample.

Often, therapeutic relationships are cross-cultural in nature, which places both nurses and patients at risk for stress, depression, and anxiety. The purpose of this investigation was to describe novice nurses' level of global interdependence identity, as manifested by worldminded attitudes, and identify the strongest predictors of worldminded attitudes. Prospective descriptive with multiple regression study. The various nursing units of a large hospital in the great Cleveland, OH, area. The participants were novice nurses up to two years after graduation from nursing school and employed as hospital clinicians. Descriptive statistics with the mean and standard deviation of the scores was used for the delineation of the development of the participants. The study relied on a survey instrument, the Scale to Measure Worldminded Attitudes developed by Sampson and Smith (1957). The numerical data was scored and organized on a Microsoft Excel spreadsheet. The Statistical Package for Social Sciences (SPSS) version 21 was the program used to assist with analysis. The assessment of the models created through regression was completed using the model summary and analysis of variance (ANOVA). The nurses' mean level of global interdependence identity was slightly above the neutral point between extreme national-mindedness and full development of global interdependence identity. The best predictors of worldminded attitudes were immigration, patriotism, and war conceptualized under a global frame of reference. Novice nurses did not demonstrate an optimum developmental status of global interdependence identity to safeguard cross-cultural encounters with patients. The recommendation is the inclusion of immigration, patriotism, and war in the nursing curriculum and co-curriculum to promote student development and a turnaround improvement in patient experience.

Recent epidemiological studies have shown that periodontal infection is a risk factor for a number of systemic diseases and conditions. In addition to the conventional risk factors, chronic infection and the subsequent generation of a systemic inflammatory response may be associated with this increased risk. This study was conducted to determine whether the presence of chronic periodontitis and subsequent non-surgical periodontal therapy could influence the serum levels of interleukin-6 and C-reactive protein (CRP) in patients with severe chronic generalized periodontitis. Participants were selected from subjects who attended the Department of Periodontics and Oral Implantololgy, Government Dental College, Thiruvananthapuram. Sera were obtained from 25 patients with periodontitis for baseline examination and reassessment after completion of treatment. As a control, sera were also obtained from 20 subjects without periodontitis. Interleukin-6 was determined by sensitive enzyme-linked immunosorbent assay, and high-sensitivity CRP (hsCRP) was measured using latex turbidometric immunoassay. Data were analyzed using computer software, Statistical Package for Social Sciences (SPSS) version 10. The level of interleukin-6 and hsCRP in the sera of periodontitis patients was seen to be higher than those of healthy controls. Interleukin-6 level tended to decrease with improvement of the periodontal condition following treatment and approached that of control subjects, and this decline was statistically significant. The hsCRP levels also showed a decreasing trend following periodontal treatment. In this study, we were able to show that periodontal disease significantly affects the serum levels of systemic inflammatory markers and that non-surgical periodontal therapy could bring about a decrease in the levels of these inflammatory markers.
