Background: Fourier transform infrared spectroscopy (FTIR) combined with chemometric techniques have been employed for qualitative analysis of proteins in blood serum.Objective: The aim of this study was to suggest a diagnostic method for stage determination of chronic kidney diseases (CKD).Methods: This laboratory study was conducted in Faculty of Science of Imam Khomeini International University during 2010-2011. 50 samples were evaluated using Fourier transform infrared spectroscopy. 0.5 ml of blood serum was poured in FTIR cell for each sample. The samples were from different stages of CKD and their stages were verified by Jaffe method as gold standard (Distribution of stages was as follows: 9 stage I/ healthy, 7 stage II, 11 stage III, 8 stage IV, 5 stage V and 10 stage VI). The samples were evaluated by Quadratic discriminant analysis (QDA). Data were modified with wavelengths selection algorithms using the Successive Projection Algorithm (SPA) and the Genetic Algorithm (GA) and were applied for prediction of serum samples status with different stages of CKD.Findings: Quadratic discriminant analysis together with successive projection algorithm and genetic algorithm as wavelength selection strategies are suitable for prediction of CKDs. The correct classification rates of the samples were 85% and 97% for SPA and GA models, respectively.Conclusion: With regards to the results, this new diagnostic method can be used for multi-stage classification of the chronic kidney disease as an improved method.

Background: Despite the importance of metabolic syndrome and its components in the incidence of noncommunicable diseases especially cardiovascular diseases, its prevalence, incidence and trend are not clear.Objective: The aim of this study was to determine the prevalence of metabolic syndrome and its components in Qazvin, Iran.Methods: This descriptive study was conducted in 996 men and women over 24 years old in mindoodar district of Qazvin, 2012. Data were collected using interview, past medical and drug history and anthropometric and biochemical measurements.Findings: The prevalence of metabolic syndrome was 33% (30.9% in men and 34.9% in women) and increased with age. The most common component of metabolic syndrome was low high density lipoprotein (HDL) cholesterol (66.6%) and the least prevalent component was high blood pressure (24.8%). The order of prevalent components was different according to gender. In men the most common component was low HDL cholesterol which was followed by high level of serum triglycerides and impaired fasting glucose. In women the most common component was low HDL cholesterol which was followed by central obesity and high level of serum triglycerides.Conclusion: High prevalence of metabolic syndrome and its related risk factors that increase with age, other diseases and their complications necessitates the implementation of efficient preventive programs to decrease the related risk factors.

Background: Hepatitis B is the most common occupational hazard in health personnel especially those that do not adhere to standard precautions in occupational exposures. Fatal complications and the lack of specific treatment for this infection have driven the attention of health researchers to the education of preventive methods.Objective: The aim of this study was to design a valid and reliable tool with sociological characteristics in order to measure seven behavioral factors controlling hepatitis B.Methods: This descriptive study was conducted in 135 health personnel that were selected by two stage cluster random sampling method in Tehran during 2012-2013. The questionnaire was designed according to the definition recommended by Green and Kruter. Validity was determined in terms of face, content and construct validity. Reliability was determined by internal consistency and test-retest using the Cronbach’s alpha coefficient.Findings: The content validity ratio was greater than 0.80, the content validity index was greater than 0.79 and the Cronbach’s alpha coefficient was 0.82. Exploratory factor analysis extracted seven factors that could predict %76.5 of the variance. Based on confirmatory factor analysis, the reliability of the model was fitted to 0.91.Conclusion: With regards to the results, the questionnaire obtained from this study can be used for research, education and practical purposes.

Background: Macrolide-resistant streptococcus isolates may show constitutive or inducible resistance to clindamycin.Objective: The aim of this study was to determine the frequency of erythromycin resistant phenotypes in streptococcus isolates from laryngoscopes in Shahid Rajaei hospital, Qazvin.Methods: This descriptive study was conducted in streptococcus isolates from laryngoscopes in Shahid Rajaei hospital, 2013. The isolates were examined by Kirby Bauer disc diffusion method using erythromycin and clindamycin disks on Mueller-Hinton agar (according to Clinical and Laboratory Standards Institute standards). Inducible clindamycin resistance was tested by D-test in erythromycin resistant isolates. Data were analyzed using Chi-square test.Findings: The phenotypes detected among the 23 isolates were as follows: one (4.35%) inducible clindamycin resistance (iMLSB), 6 (26.11%) constitutive clindamycin resistance (cMLSB), 5 (21.72%) MS phenotype and 11 (47.82%) wild type. The association between erythromycin and clindamycin resistance of the streptococcus isolates and D-test was not statistically significant.Conclusion: With regards to the results, laryngoscope can potentially carry erythromycin and clindamycin resistant isolates. Therefore, infection control is necessary before using this instrument.

Background: Emotional Intelligence is important in the success of people in healthcare organizations. Nurses who have higher Emotional Intelligence can improve the quality of care and increase satisfaction with proper communication with patients.Objective: The aim of this study was to determine the association of emotional intelligence and communication skills with patients in nurses. Methods: This analytical study was conducted in 80 male and female nurses that were selected by quota sampling method from selected hospitals in Qazvin University of Medical Sciences. The measurement tools were Emotional Intelligence and communication skills questionnaires. Data were analyzed using T-test, ANOVA and Pearson’s correlation coefficient.Findings: There was a positive significant correlation between emotional intelligence and communication skills. The associations of the demographic differences (gender, age, work experience, education level and type of employment) with emotional intelligence and communication skills were not statistically significant.Conclusion: With regards to the results, it is suggested to consider the emotional intelligence training in hospitals. Since increasing Emotional Intelligence is an effective way to improve communication skills of nurses and therefore improve the quality of nursing care.

A few decades ago, drugs which were used to treat different diseases were only limited to chemical drugs, peptides, monoclonal antibodies and recombinant proteins. Since the first nucleotide drug was approved by the Food and Drug Organization of the United States, this new generation of medications became remarkable to researchers and pharmacists. Ribonucleic acid (RNA) based drugs were among these category that encountered a number of hurdles along the way such as potential immunogenicity, structural instability and the need for a vehicle to deliver the drug into the cell. With regards to the simplicity of the RNA therapeutics design, researchers could overcome the challenges with improvements in synthetic delivery carriers and chemical modifications of the RNA therapeutics. Numerous types of RNA-based drugs are being extensively tested in various stages of clinical trials. This review focuses on therapeutic ribozymes, antisense oligonucleotides, interfering RNAs and aptamers.
