- چکیده انگلیسی: Background: Ventilator-associated pneumonia (VAP) is the second common nosocomial infection in NICUs leading to some complications. Nurses are one of the main resources in health care that directly influence neonatal health care. Responsibility of most of preventive strategies related to VAP complications lies with nurses; therefore, nursing care should be assessed until the nurses show standard level of performance in hospitals. The aim of this cross-sectional study, conducted within 2015-2016, was to assess nursing care regarding VAP prevention in neonatal intensive care units (NICUs) in selected hospitals affiliated to Shahid Beheshti University of Medical Sciences.
Methods: In this descriptive cross-sectional study, 100 observations of nursing care regarding VAP were selected by convenience method in NICUs of Mahdiyeh, Mofid, and Imam Hossein hospitals affiliated to Shahid Beheshti University of Medical Sciences within 2015-2016. The data collection tools included demographic information questionnaire and a developed checklist related to VAP prevention. The observations were assessed and documented with two sampling methods, including time and event sampling. The data were analyzed in SPSS software (version 16).
Results: According to the results of the current study, the rate of compliance of nursing care with the standards for prevention of VAP in neonates under mechanical ventilation in NICU with developed standards was estimated at 62.81 percent.
Conclusion: Authorities should pay more attention to nursing cares especially incompetent cares explained in this study to increase the health of hospitalized neonates, decrease complications, length of stay, and costs. Moreover, future research is needed to investigate the reasons of this incompetency.- انتشار مقاله: 19-10-1397

- چکیده:
- چکیده انگلیسی: Background: Sexual compatibility between husband and wife is an effective factor in both sexual and
marital satisfaction. However, there is limited valid and reliable questionnaire to measure the degree
of sexual compatibility between the couples.
Methods: In this exploratory mixed method study, 54 individuals were interviewed in the qualitative
phase and 448 persons participated in the quantitative phase. Totally 502 participants (261 woman,
241 men) took part in this study. According to 205 final codes derived from the qualitative phase,
102 initial items were developed, the number of which reached 69 items after deletion and merging
performed by the research team. After face validity, content validity and construct validity, 68 items
were introduced into the construct validity phase.
Results: Following exploratory factor analysis and promax rotation, the items were reduced to 35 in
4 factors: “Requirements of a sexual relationship”, “Sexual agreement”, “Contextual obstacles” and
“Outcomes of sexual compatibility”. The questionnaire Cronbach alpha and correlation coefficient of
the test-retest method were 0.90 and 0.91, respectively.
Conclusion: Final Questionnaire included 35 items in 4 point-Likert scale with total score of between
35-140. This valid and reliable questionnaire is brief, easily interpreted and can
measure the main
factors affecting sexual compatibility with the spouse in clinics and research fields.- انتشار مقاله: 28-03-1398

- چکیده:
- چکیده انگلیسی: Background: Different patterns of gender-based relationships between attitude toward smoking and self-esteem with smoking behavior have reported. However, such associations may be much more complex than a simply supposed linear relationship. We aimed to propose a method of providing hand details on the total and gender-based scenarios of the relationships between attitude toward smoking and self-esteem with smoking.
Materials and Methods: A secondary analysis conducted on a data set obtained for a cross-sectional study among 4,905 male and female high school students in Tabriz, Iran (2012). We randomly selected 196 classes in a clustering process and invited all the students in the classes to participate in the study; then, investigated the relationship between smoking with attitude and self-esteem, as explanatory variables. We also found the data to fit a nonlinear functional relationship and to be free from normal condition due to applying Bayesian nonparametric functional latent variable model.
Results: Among all the students, attitude was found as the only variable with conceptual effect on smoking (p<0.05). Among boys, self-esteem showed no conceptual effect on smoking which was in contrast to those found among girls. Smoking among male students with low self-esteem was high, but it was gradually decreasing by rising self-esteem. Among girls, in contrast, smoking was descending by decreasing self-esteem.
Conclusion: The relationships between self-esteem and attitude with smoking may not be necessarily linear. Being at the high levels of self-esteem among boys may lead to the reduced levels of smoking, and among girls may result in the increased level of the behavior.- انتشار مقاله: 06-08-1396

- چکیده:
- چکیده انگلیسی: Background: One of the malignant tumors is Breast Cancer (BC) that starts in the cells of breast. There is many
models for survival analysis of patients such as Cox PH model, Parametric models etc. But some disease are that
all of patients will not experience main event then usual survival model is inappropriate. In addition, In the presence of
cured patients, if researcher can specify distribution of survival time, usually cure rate models are preferable to
parametric models. Distribution of Survival time can be Weibull, Log normal, Logistic, Gamma and so. Comparison of
Weibull, Log normal and Logistic distribution for finding the best distribution of survival time is purpose of this study.
Material and Methods: Among 787 patients with BC by Cancer Research Center recognized and followed from
1985 until 2013. Variables stage of cancer, age at diagnosis, tumor size and Number of Removed Positive Lymph
Nodes (NRPLN) for fitting Cure rate model were selected. The best model selected with DIC criteria. All analysis
were performed using SAS 9.2. Results: Mean (SD) of age was 48.47 (11.49) years and Mean of survival time and
Maximum follow up time was 326 and 55.12 months respectively. During following patients, 145 (18.4%) patients
died from BC and others survived (censored). Also, 1-year, 5-year and 10-year survival rate was 94, 77 and 56 percent
respectively. Log normal model with smaller DIC were selected and fitted. All of mentioned variables in the model
were significant on cure rate. Conclusion: This study indicated that survival time of BC followed from Log normal
distribution in the best way.- انتشار مقاله: 20-08-1396

- چکیده:
- چکیده انگلیسی:
Background: In its standard form, the parametric survival model assumes that the shape parameter is constant and the scaling parameter is not. This article focuses on how a model with a non-constant shape parameter could make differences in oncology studies and lead to more precise results. Materials and Methods: Online data for part of a large clinical trial conducted by the Radiation Oncology Group in the United States available online on UMass Amherst`s website were employed. The full study included patients with squamous cell carcinoma from fifteen sites in the mouth and throat, although only data on three sites in the oropharynx reported by the six largest institutions were considered here. To identify clinical, pathological and biological characteristics of patients which might have had an effect on their survival, we compared Weibull distributions once with a constant shape parameter and again with a non-constant shape parameter. Analyzes were performed using SAS university edition. The level of significance was set at P ≤ 0.05. Results: Based on the model with a constant shape parameter only the patient status was identified as a risk factor and the AIC of this model was 2152.4, but based on the model with a non-constant shape parameter, sex, patient status, stage of the tumor and the institute at which the patient had been treated were significant, with an AIC of 2150.1. Conclusion: On the basis of the AIC, the second model with a non-constant shape parameter was suggested to be more accurate for identifying risk factors, leading to more precise results.- انتشار مقاله: 01-12-1395
