The study of patient care behaviors and its effective factors from the perspective of nurses working in Ardabil educational hospitals 2017
Get PDFBackground and Aim: Understanding nurses perceptions of care behaviors and determining the factors affecting it is the first step in correcting inappropriate behaviors and improving the quality of nursing care. Therefore, this study was conducted with the aim of "determining care behaviors and its determinants from nurses' point of view in Ardabil educationalhospitals ".
Methods: This was a descriptive cross-sectional study with 450 nurses working in Ardabil educational-therapeutic hospitals in 2017. Sampling method was stratified random. Data were collected using a standard three-part questionnaire on demographic characteristics, Wolf caring behaviors and the determinants of nursing care behaviors. Data were analyzed using descriptive statistics (mean and standard deviation) and analytical (Mann-Whitney, Kruskal-Wallis, Anova and Multivariate Regression Analysis) statistics in SPSS v21 software.
Results: Nurses' caring behaviors with a mean and standard deviation of (5.27±0.24) were at the optimum level. From nurses' point of view, physical dimension of care (5.43±0.7) was more important than psychosocial dimension (5.17 ± 0.6) (p = 0.001). The most important caring behaviors for nurses were medication (5.58±0.44) and the least important caring behaviors were the patient's calling with her favorite name (4.02±0.86). Mean scores of caring behaviors in female nurses (5.26 ± 0.7) were more than males (4.97 ± 0.54) (p = 0.001). The most important factor influencing nurses' caring behaviors was the responsibility (4.49 ± 1.01) and the least important factor related to the patient's characteristics (3.50±1.1).
Conclusion: The results showed that nurses' care behaviors were in the desired and focused on the physical aspect of care. Therefore, in order to provide patient satisfaction, nurses should pay attention to both dimensions of caring behaviors (physical and psychosocial). It is suggested that psychosocial care should be emphasized in nursing in-service training
Effect of pentoxifylline and captopril combination therapy versus captopril monotherapy on blood pressure control in patients with hypertension at Tabriz Shahid Madani Hospital: A pilot randomized clinical trial
Get PDFPurpose Hypertension has received too much attention because of its high prevalence, its association with concomitant risk factors and mortality. Considering the pathophysiology of hypertension and the key role of blood viscosity (BV) in the regulation of blood pressure (BP), and also hemorheological effects and cardiovascular benefits of pentoxifylline (PTX), this study was conducted to evaluate whether PTX can reduce BP when added to captopril in patients with stage 1 hypertension.
Methods In this pilot randomized clinical trial 62 patients at the age of 18 to 80, with diagnosis of stage 1 hypertension were entered. The intervention group (n=30) received 1200 mg PTX in three divided doses plus 25 mg captopril three times a day whereas, the control group (n=32) received only 75 mg captopril in three divided doses. Measurements of BP were done according to American Heart Association (AHA) guidelines at baseline, first and second month of the study period. Major adverse cardiac events (MACEs) during this period were recorded as secondary end points of the study.
Results Comparing the systolic blood pressure (SBP) levels in the groups of intervention and control no significant differences were noted at baseline (150.4±6.03 vs.150.4±6.2, p=0.98), first (138.4 ±9.4 vs. 142.3 ±5.6, p=0.08) and second (134.6 ±8.9 vs. 137.4±6.0, P=0.20) months of the study respectively. Similarly, no significant differences were observed in the diastolic blood pressure (DBP) at baseline (91.7±3.9 vs. 92.0 ±3.7, p=0.84), first (85.5±5.1 vs. 86.9 ±3.8, p=0.27) and second (82.6 ±5.7 vs. 84.0 ±3.5, p=0.31) months. About baseline demographic data of patients, no significant differences were observed between the two groups.
Discussion and Conclusions Based on the results of present study, adding PTX as a hemorheological agent to captopril could not significantly reduce blood pressure in the patients with stage 1 hypertension. Our findings are in accordance with previous studies however, they were not well designed for measuring BP. Further larger-scale studies are needed to confirm these findings
Phytochemical Analysis and Various Biological Activities of the Aerial Parts of Scrophularia Atropatana Growing in Iran
Get PDFScrophularia atropatana (S. atropatana), an Iranian plant belonging to the family of
Scrophulariaceae, was assigned for its chemical compositions and biological activities of
essential oil (EO) and extracts of the aerial parts of the plant during the flowering stage.
Combination of GC-MS and GC-FID was assessed for analyzing the chemical compositions
of the EO from the aerial parts of S. atropatana. Furthermore, Brine shrimp lethality test
and DPPH assay were performed to evaluate general toxicity and free-radical-scavenging
properties, respectively. Furthermore, anti-proliferative and antimicrobial activities were
assessed by MTT assay and disc diffusion methods correspondingly. Additionally, all the
potent samples (extracts) and its fractions in the MTT assay were further studied for the
presence of various compounds by GC-MS apparatus. MeOH extract and 40% sep-pak fraction
indicated high amounts of total phenolic (TPC), total flavonoid content (TFC), and antioxidant
properties. In the case of general toxicity, among the extracts, dichloromethane (DCM) extract
showed noticeable effect. Furthermore, DCM extract was indicated potent ability to eliminate
breast tumor cells and minimum efficacy on normal cells. Anti-microbial activity of all samples
was ignorable. The potent extracts and fractions which had more anti-proliferative activity
were further elucidated by GC-MS and showed high amounts of Alkanes and fatty acids. In
the case of EO constituents, non-terpenoids were the major compounds. To sum up, it seems
BSLT could be a good preliminary approach for evaluating the cytotoxicity in MCF-7 cell line.
Additionally, antioxidant activity, TPC, and TFC contents of all samples were in consistent
with each other
Internet addiction evaluation and its relationship with sleep quality and anxiety in students of Ardabil University of Medical Sciences in 2018-2019
Get PDFBackground: With the development of technology and increasing access to the Internet and cyberspace, we are witnessing a new type of addiction and its impact on health. Internet addiction is an emerging phenomenon that results from easy access to computers and online information and over-dependence that can have multiple effects on people. The purpose of this study was to determine the relationship between internet addiction and sleep quality and anxiety among students of Ardabil University of Medical Sciences.
Materials and Methods: This descriptive-correlational study was performed on 376 students of Ardabil University of Medical Sciences in 1397. Samples were selected by stratified random sampling from each faculty. Data were collected using demographic questionnaires, Young's Internet Addiction Questionnaire, Petersburg Sleep Quality, and Beck Anxiety Inventory. Data were analyzed by SPSS software (version 24) and descriptive statistics (mean frequency and standard deviation) and analytical statistics (chi-square, univariate regression and Pearson correlation coefficient).
Results: The results showed that 38% of students had internet addiction, 77.9% had poor sleep quality and 46.3% had abnormal anxiety. Pearson's correlation coefficient showed that Internet addiction had a negative and inverse relationship with sleep quality and a significant positive relationship with anxiety (p <0.001). When examining the relationship between anxiety and sleep quality with internet addiction, addiction predicts sleep quality (R2 = 0.06). A separate study of addiction predicts both. The results of Chi-square test showed that the average anxiety level of female students was higher than boys and there was a significant positive relationship between internet addiction and educational level (p <0.001).
Conclusion: The findings of this study showed the prevalence of internet addiction and its effect on the quality of sleep and anxiety in students. Given the increasing prevalence of Internet use, it is suggested that measures be taken to promote awareness of the impact of internet addiction on health, as well as self-care and prevention of complications among students

Synthesis of ZnO and nZVI Nanoparticles Using Pomegranate Peel Extract and Putting it on Activated Carbon Produced from Pomegranate Peel and Its Application for Removal of Cephalexin from Aqueous Media
No full textBackground and Objectives: Concerns have been raised about the presence of high concentrations of antibiotics in the environment in recent years. Conventional water purification and treatment processes cannot remove these resistant pollutants. There are various ways to remove these compounds, but the adsorption method has been more effective. Therefore, this study was performed to evaluate the efficiency of activated carbon coated with ZnO and nZVI nanoparticles for removal of cefalexin from aqueous solutions.
Materials and Methods: The present study was performed experimentally at laboratory scale in a closed system. In this study, ZnO and nZVI nanoparticles were synthesized using pomegranate peel extract. The effects of pH, adsorbent dose, initial antibiotic concentration and reaction time on the efficiency of the adsorption process were studied. Isotherms (Langmuir and Freundlich) and adsorption kinetics at different concentrations were evaluated for process evaluation. The structure of the adsorbents and their morphology were investigated by FTIR, FESEM, BET and EDX techniques. Cefalexin concentration was determined using a Perkin Elmer Lambda 25 UV/VIS Spectrometer spectrophotometer at 261 nm.
Results: The results showed that the removal rate of cephalexin increased with increasing adsorbent dose and contact time and decreased with increasing initial cephalexin concentration. The results of the isotherm and adsorption kinetics studies showed that the adsorption process on both adsorbents was more consistent with the Langmuir isotherm model with 0.9987 and 0.9991 correlation coefficients for AC-nZVI and AC-ZnO, respectively, and follows pseudo-second order kinetics. The maximum adsorption capacity of cefalexin for AC-ZnO and AC-nZVI based on Langmuir model was 83.33 and 89.28 mg/kg, respectively. The specific surface area of AC-ZnO, AC-nZVI and AC were calculated as 745.65, 827.66 and 738.17 m2/g, respectively. The results indicate the effectiveness of sodium hydroxide recovery. These results indicate that AC-nZVI and AC-ZnO were recoverable for cephalexin uptake.
Conclusion: The removal rate by both types of adsorbents was significantly high indicating the effective role of nanoparticle stabilization on activated carbon. As a result, using nanoparticle stabilization technology on activated carbon as an inexpensive and efficient adsorbent can be used to remove cefalexin from aqueous media
