Abstract

Background and Aim: A vast majority of clinical specimens are contaminated with Klebsiella species. The drug resistance among Klebsiella species is increasing day by day therefore, antibiotic senility test is necessary before prescribing antibiotics. The aim of this research was to determine the antibiotics resistance patterns of Klebsiella species isolated from clinical specimens of patients using the standard Kirby-Bauer method.

Materials and Methods: The present research was performed on 300 specimens of Klebsiella collected from Imam Khomeini hospital. After identification, drug resistance was investigated through the standard CLSI procedure. The drug sensitivity test was determined for all of the 12 antibiotics using standards of disk diffusion in agar Kirby-Bauer.

Results: The frequency rates of the isolated Klebsiella species were: pneumonia(94%), oxytoca(4%), ozaenae(1%), and rhinoscleromatis(1%). Moreover, in terms of source of infection, the collected samples in order of frequency were: urine, sputum, vagina, scar, stool, and blood, respectively. Altogether, the percentage rates of resistance were as follows: Ampicillin(97%), Amoxycillin(97%), Cefalotin(39%), Gentamicin(30%), Colistin(55%), Nalidixic acid(2%), Chloramphenicol(26%), Kanamycin(17%), Tetracycline(28%), Nitrofuration(44%), Ceftazidime(2%), and Amikacin(0%).

Conclusion: The results showed that the lowest resistance rate obtained was related to Amikacin in all tested Klebsiella therefore, it can be recommended as the most effective antibiotic.

Volume 14, Issue 6 (Feb & Mar 2021)
Abstract
Background and Aim: Multiple sclerosis (MS) is a progressive disease of the central nervous system, of which the symptoms and problems reduce the quality of life. Recent research has identified sport exercises as an important part of healthy lifestyle in reducing the symptoms of the disease and improving the quality of life; however, the most effective type of exercise is not yet clearly known. The aim of this study was to provide information about the beneficial effects of exercise in MS patients and guidelines for prescribing exercise programs for them.
Materials and Methods: This article is an overview of the ways different sport exercises affect MS. To access scientific articles, databases of PubMed, SID, Google Scholar, and Mag Iran, and the keywords including multiple sclerosis (MS), aerobic training, resistance training, and combined training were used.
Results: Recent reports show that different types of sport exercises lead to a significant increase in the improvement of MS symptoms, although there are many discrepancies between researchers in prescribing different exercise programs (various training protocol, duration, and intensity). However, according to the results of studies, regular moderate-intensity exercise training leads to the functional benefits and improvement and control of the disease process without exacerbation of inflammation through various physiological mechanisms. thus, contrary to popular belief, modulated exercise training can have beneficial effects on MS patient.
Conclusion: Based on the findings of the present study, regular exercises (aerobic, resistance and combination) with moderate intensity improve the symptoms of MS and increase the quality of life.

Zahra Otroj, Firoozeh Zare-Farashbandi, Fatemeh Rastegari,
Volume 16, Issue 2 (Jun 2022)
Abstract
Background and Aim: Health information seeking behavior can be influenced by several factors and variables such as personality traits, beliefs, values, tendencies, contextual factors and personal emotions. Health information has a direct relationship with the quality of life of people in society, it can be influential in decisions related to personal and social health and improve people’s performance in this field. This study aimed to determine the relationship between personality types of graduate students of Isfahan University of medical Sciences (IUMS) and their health information seeking behavior based on the Miller model.
Materials and Methods: This was an applied survey study. The study population was all graduate students of IUMS. The sample size was determined using the Morgan table of 297 people. Data collection tools are Neo Five Personality Factor Questionnaire and Miller Information Behavior Questionnaire. Data were analyzed by SPSS software.
Results: The results showed that there is an inverse relationship between personality type “Psychotic” and the component of “active search for health information”. Also there is a direct relationship between persons who are “Eager for new experiences” and “conscientiousness” with the component of “active search for health information”. But there is no significant relationship between personality types “extroversion” and “agreeability” with the components of health informing behavior. The studied students are not responsible and conscientious in terms of personality type, they often prefer solitude and are introverted and conservative. But more than half of them are balanced in the dimension of “agreeability”.
Conclusion: This study showed that people who are eager for new experiences and conscientious, search health information actively, but Psychotic persons are not willing to be active in seeking health information This means that the more responsible and conscientious people are, or the more eager they are for new experiences, the more actively they search for health information. Therefore, it is better for health policy makers to plan in such a way that the necessary health information is provided to them interactively based on the personality of the people.
