Behavioral risk factors of noncommunicable diseases (NCDs) are established during early age and continued into adulthood. In Bangladesh, the scenario of NCD risk factors among students was inadequately studied. The aim of this study was to assess and compare the prevalence of behavioral risk factors of NCDs between undergraduate medical and nonmedical students. This cross-sectional study was conducted among 280 undergraduate students (equal number of students from medical and nonmedical backgrounds). Respondents were selected purposively from 5 purposively-selected institutions. Modified WHO STEPS instrument was used for data collection. Respondents were asked about their behavioral risk factors (tobacco use, insufficient fruit and vegetable intake, inadequate physical activity, and alcohol consumption) by face-to-face interviews. Men students were more in both groups. The mean age of the medical and nonmedical students was 22.1±2.0 and 21.8±1.9 years, respectively. Tobacco use was more among nonmedical students than that among the counterpart (22.1% vs. 15.7%). Medical students were more used to take insufficient fruits and vegetables compared to nonmedical students (97.9% vs. 93.6%). Equal proportions (71.4%) of students in both groups were used to perform inadequate physical activity. Alcohol consumption was observed more among nonmedical students (12.9% vs. 8.6%). Behavioral risk factors of NCDs were remarkable among students of both groups, mainly among nonmedical students.

Level of satisfaction and opinion of patients are important factors that might be considered in assessing the quality of health care services. This study aimed to assess the level of satisfaction of patients who visited dental clinic of School of Dentistry, Shahrekord University of Medical Sciences, Shahrekord, Iran. This descriptive, analytical, cross-sectional study was conducted in 2015 on 400 randomly-selected patients visiting Endodontics, Periodontics and Implant, Pediatric Dentistry and Operative Dentistry Departments of Dental Clinic of School of Dentistry, Shahrekord University of Medical Sciences. A questionnaire encompassing demographic information and perspectives on dental care, some clinic-related factors, quality of received services, waiting time, and behavior of dental clinicians and personnel was filled out by the patients. Data were analyzed using SPSS version 22.0. Of all the patients, 77% (n=310) reported improvement in their conditions and were completely satisfied with the received services; 12% reported worsening conditions and so they were dissatisfied with the treatments; and 19.5% (n=78) reported no change in their conditions. The highest level of satisfaction was related to quick presence of dental clinicians and their behavior. Patients were mainly dissatisfied with the treatment costs and welfare services. Satisfaction of patients with the services provided by the dental clinic of School of Dentistry, Shahrekord University of Medical Sciences was at an acceptable level. Items causing dissatisfaction in the patients should be properly addressed in order to maximize the satisfaction rate of patients with the services provided in this clinic.

Organizational support of family members of the patients admitted to intensive care units (ICUs) potentially reduces mental stresses and enables them to better comply with and support the patients. The current study aimed at evaluating the needs of families of the patients admitted to ICUs in teaching hospitals of Iran. This cross-sectional study was conducted in 2015 using convenience sampling method. The Critical Care Family Needs Inventory (CCFNI) in 5 factors was used as a main data collection tool. The study population included 235 family members of the patients. Total score of CCFNI was 132.32±18.46. Needs of family members of ICU patients decreased 0.428 times following the increase of length of stay in ICU (P < 0.001). Moreover, the need for supportive cares was significantly 9.273 times lower among illiterate families, compared with the ones with higher education level (P < 0.018). Considering that the highest need was in the area of support and the predictors of the family needs of the patients were the duration of hospitalization and the educational status of their families, the main focus of nurses should be on the support of family members of the patients admitted to the ICU and supporting and paying attention to their needs, who experience stressful conditions, to satisfy them and even to encourage them to give better care to the patient and help health care staff.

Maintaining the health of diabetic people depends on the self-management of the disease. This study aimed to evaluate the relationship of distress, self-efficacy, perceived social support, and self-care with self-management behaviors in the patients with type 2 diabetes. The present analytical-descriptive study was conducted on 228 diabetic patients, during 2016-2017. Most of the participants were male (60.6%) and the mean age of them was 51.95±15.04. The participants were selected based on a simple random sampling method after completing the consent form. The required data were collected through questionnaires of distress, self-efficacy, perceived social support, self-care, and self-management. The data were statistically analyzed using SPSS software version 22.0. Out of 228 participants, 77.3% were married and the highest frequency in terms of educational attainment was related to those with a high school diploma. The results indicated that the duration of affliction with diabetes was less than 10-15 years in 88.9% of the participants. Pearson correlation test demonstrated that the total score of self-management had a significant relationship with the total scores of distress, perceived social support, self-efficacy, and self-care (P<0.005). The results of regression analysis also indicated that distress, perceived social support, self-efficacy, and self-care had a predictive power of 0.43% for self-management. Among these variables, the predictive powers of self-efficacy and self-care were statistically significant, and the prediction rate of self-efficacy was more than that of other ones (β = 0.17). The study findings showed that the researchers who want to perform interventions based on cognitive-social theory should mainly focus on self-care and self-efficacy.

Although chronic bronchitis is markedly under-diagnosed in the general population, it has a significant impact on the health status and the well-being of patients as well as healthcare resource consumption. This study aimed to determine the prevalence of chronic bronchitis and its correlates in the northwest of Iran. In 2014, all residents aged 35 and over in Khameneh city, East Azerbaijan, were invited to participate in the pilot phase of the Azar cohort study. The respiratory symptoms questionnaires were filled out by two trained general practitioners. Participants with a cough and phlegm on most days during at least three successive months in the previous two years were classified as chronic bronchitis group. Chi-square test was used to compare the chronic bronchitis and smoking status between males and females. A total of 1036 participants were interviewed, 1006 of whom had completed a respiratory questionnaire, from them 544 (54.1%) were females, and 462 (45.9%) were males. The mean age was 52.5 ± 10.5 years. The prevalence of smoking was 16.2%. According to the chronic bronchitis definition, 24 (2.4%) subjects were classified with chronic bronchitis, and the prevalence was higher in the males (4.1%) than that in the females (0.9%). The prevalence was higher among the active smokers and ex-smokers compared to non- smokers (8.6% and 4.1% vs. 0.8%). The prevalence of cigarette smoking was 16.2% and it was higher in the males than that in the females (33.5% vs. 1.5%). the prevalence of chronic bronchitis in the population of the region under study was relatively low in comparison to the other parts of Iran and its prevalence was higher in the males than that in the females.

Antioxidant defense plays a vital part in organism protection against oxidative stress which is produced by reactive oxygen species (ROS). Oxidative stress represents a serious threat to the animals facing with heavy metals. This study was designed to analyze the habitat suitability for Caspian pond turtles, namely, Mauremys caspica caspiica in Mazandaran province by measuring lead (Hg) and mercury (Pb) tissues concentrations and heavy metals’ effects on the health status Caspian pond turtles through quantifying the oxidative stress factors. Hg and Pb were measured in kidney and liver tissues of 20 sampled Caspian pond male turtles (treatment group) using atomic absorption spectrometry (AAS) and a Caspian pond male turtle was included in the control group. Moreover, glutathione (GSH) level, catalase (CAT), and superoxide dismutase (SOD) activities were investigated in kidney and liver tissues. The mean (SD) concentration of Pb and Hg were 35.83 (4.20), and 0.604 (0.03) mg/kg for the sampled livers and also 31.01 (3.42) mg/kg and 0.316 (0.04) mg/kg for the sampled kidneys, respectively. Levels of trace elements, CAT, and SOD activities were found to be higher in the liver. Totally, GSH levels, as well as, CAT, and SOD activities were found to be higher and lower, respectively, in the control turtle as compared with the contaminated Caspian pond turtles. Trace-element levels had a positive correlation with CAT and SOD activities while having a negative association with GSH levels in contaminated Caspian pond sampled turtles. According to the results, it was inferred that high Hg and Pb concentrations in the turtles were due to the heavy metal contamination of their habitat in Mazandaran province. Based on the positive correlation between the heavy metal concentration of the tissue and dysfunction of oxidative stress defense markers, it can be concluded when the Caspian pond turtles are faced with heavy metal contamination risk, these markers can act as a bioindicator of their health status. No doubt, more studies are required to prove this hypothesis.

Endocrine-disrupting compounds (EDCs) as active biological compounds can pose a threat to the environment through acute and chronic toxicity in organisms, accumulation in the ecosystem, and loss of habitats and biodiversity. They also have a range of possible adverse effects on environmental and ecological health. Estradiol, as one of the natural estrogenic hormones released by the humans and livestock, may exert endocrine-disrupting effects on the nanogram-per-liter range and cause serious problems for the aquatic organisms and animals in many aquatic systems. Various studies have reported the presence of synthetic estrogens such as 17 alpha-ethinyl estradiol (EE2) and natural estrogens including 17 beta-estradiol (E2) in wastewater sludge, surface water, river bed sediment, and also digested and activated sludge. The aim of the present study was to review and evaluate the endocrine disrupting compounds especially 17 beta-estradiol, as a representative of estrogen hormones present in the environment and their disturbing effects on humans and wildlife.

The food-borne pathogens appear to be a reemerging and endless problem in the human community all over the world. Hence, all the outbreaks should be constantly monitored for pandemic strains and new mutant genotypes. The main purpose behind the molecular typing is the comparison of bacterial isolates to obtain genomic relatedness regarding epidemiological aspects. One of these methods that have been recently reported in several Iranian studies is pulse field gel electrophoresis (PFGE). The aim of this study was to review and discuss the current situation and difficulties, and also the necessity of planning for tracking new and re-emerging food-borne pathogens investigating PFGE future status in Iran as a molecular epidemiology tool. According to the results, it was found that this technique requires high investments in both fields of required equipment and software some of which are now available in many research centers. In addition, investigations on various medical search engines revealed that hundreds of studies have been published after 2010 in Iran. These reports indicated that most of these studies were not able to provide an efficient epidemiological analysis of the outbreaks and prevention of future events, except for a few exceptions. A review of the capabilities available in the country in this respect led the researchers to infer that it may be the best time to make a plan on the existence of a general network of collecting and analyzing the results, as well as integrating them into the international databases. It is expected that these responsible institutions to make the required design in this field.
