Therefore, it is very important to investigate the possible geographical variations of in-hospital stroke mortality and to identify its associated factors. Methods: This historical cohort study included suspected stroke cases transferred to Ghaem Hospital of Mashhad by the EMS from March 2018 to March 2019. Using emergency mission IDs, the pre-hospital emergency data were integrated with the patient medical records in the hospital. We used the Bayesian approach for estimating the model parameters. Results: Out of 301 patients (142 (47.2%) females vs. 159 (52.8%) males) with a final diagnosis of stroke, 61 (20.3%) cases had in-hospital mortality.Results from Bayesian spatial log-logistic proportional odds (PO) model showed that age (PO=1.07), access r...

The purpose of study was the effectiveness of life skills education based on Quranic verses on religious orientation and general health of students. Methods: This study is a randomized Controlled clinical trial. In the first stage, sampling was done in an improbable and purposeful method, and in the second stage, the allocation of individuals in two groups was performed as a controlled clinical trial using the envelope allocation method. First, interested students in the girls' dormitories of Mashhad University of Medical Sciences were asked to complete the questionnaires of religious orientation and public health and 30students who gained the highest scores were selected and randomly assigned in two groups. The obtained data were analyzed with statistical method Analysis of Covariance by using SPSSv25. Results: At the end of the study, there was a significant difference between the mean of the general health score of two group (P<0.001).whereas there was no significant difference between the means of the two groups in religious orientation (P=0.26). Conclusions: Educational intervention of life skills with the orientation of Quranic verses was effective in the general health of students. While it had no effect on the religious orientation of students. So, counselors and professionals of mental health can help students by using Quranic verses in teaching life skills.

There are remarkable geographical variations in the accessibility to emergency medical services (EMS). Moreover, transport delays have been documented to affect stroke outcomes. This study aimed to examine the spatial variations in in-hospital mortality among patients with symptoms of stroke transferred by EMS, and determine its related factors using the auto-logistic regression model. Methods In this historical cohort study, we included patients with symptoms of stroke transferred to Ghaem Hospital of Mashhad, as the referral center for stroke patients, from April 2018 to March 2019. The auto-logistic regression model was applied to examine the possible geographical variations of in-hospital mortality and its related factors. All analysis was performed using the Statistical Package for the Social Sciences (SPSS, v. 16) and R 4.0.0 software at the significance level of 0.05. Results In this study, a total of 1,170 patients with stroke symptoms were included. The overall mortality rate in the hospital was 14.2% and there was an uneven geographical distribution. The results of auto-logistic regression model showed that in-hospital stroke mortality was associated with age (OR = 1.03, 95% CI: 1.01-1.04), accessibility rate of ambulance vehicle (OR = 0.97, 95% CI: 0.94-0.99), final stroke diagnosis (OR = 1.60, 95% CI: 1.07-2.39), triage level (OR = 2.11, 95% CI: 1.31-3.54), and length of stay (LOS) in hospital (OR = 1.02, 95% CI: 1.01-1.04). Conclusion Our results showed considerable geographical variations in the odds of in-hospital stroke mortality in Mashhad neighborhoods. Also, the age-and sex-adjusted results highlighted the direct association between such variables as accessibility rate of an ambulance, screening time, and LOS in hospital with in-hospital stroke mortality. Thus, the prognosis of in-hospital stroke mortality could be improved by reducing delay time and increasing the EMS access rate.

Certain arthropods, such as mites and cockroaches, contain protozoa like Lophomonas blattarum in their intestines to help with digestion that may have some role in AR. We aimed to determine the frequency of L. blattarum in nasal smears of patients with AR in comparison with healthy controls. Methods: In this prospective cross-sectional study (March 2015-March 2016), 36 patients with a clinical presentation of AR (with a positive prick test including mites) and 34 normal controls were included at ear, nose, and throat (ENT) clinic at Imam Reza Hospital of Mashhad, Iran. Nasal secretions were evaluated to examine presence of L. blattarum in the patients and control group by direct method. Diagnosis of L. blattarum was based on microscopic observation both on direct smear and Giemsa stained specimens. Results: Patients with AR had a higher frequency of L. blattarum ...

Honey has several anti-microbial, anti-oxidants, healing, and anti-inflammatory properties which may reduce the need for steroids in this situation. Therefore, the aim of this study is to show the effect of standardized honey on mucosal healing of the nose and paranasal sinuses after polypectomy. Design and method: In this double-blind, randomized, placebo-controlled clinical trial, 28 patients with nasal polyposis underwent functional endoscopic sinus surgery (FESS). Besides common post-op medications, normal saline (as placebo) and diluted processed honey were used separately in the two nostrils of each patient. Two endoscopic follow-ups using the Philppot-Javer (P-J) scoring system were performed to assess the healing and recurrence of polyps on either side. The secondary outcome measure was the patients’ satisfaction rate. Results: The patients’ mean age was 38.03±11.9 years. 15(57.7%) had a positive prick test ...

Therefore, we used structural modeling to test a hypothesized model to identify factors associated with hypertension. Methods: A cross-sectional population based survey, was performed and the data related to a random representative sample of 9704 subjects of MASHAD study were used. Then, we determined the relationship between risk factors for hypertension using structural equation modeling technique. The data were analyzed using Amos V. 22. Results: The conceptual model was validated by Goodness of Fit Indexes (CFI=0.939, TLI=0.908, NFI=0.935, RMSEA=0.04, SRMR=0.037). Obesity and lack of physical activity had the greatest impact on blood pressure. Discussion: Findings show evidences to confirm the conceptual model considered in the risk factors for hypertension that can be helpful in policies for preventing hypertension and consequently, the disabilities that arise from it. Highlights ● Fit indices indicate that the first proposed model fits poorly to the data. P values associated with SES, poor diet, and physical activity with blood pressure and also age and triglycerides were lower than 0.01, so their direct effects were removed. ● After modifications, the model showed a good fit with the sample data. CFI and TLI and NFI index values were greater than 0.9; RMSEA and SRMR were less than 0.05. ● Waist to hip ratio (WHR) appears to be more appropriate to represent obesity according to factor loadings. ● There are risk factors that do not directly increase blood pressure but indirectly affect it. For example, physical activity and diet may not directly increase blood pressure but they can be affected by other variables that cannot be ignored. ● Age, obesity, and physical activity were the most important factors on increasing blood pressure. Plain Language Summary Given the importance of hypertension in health sciences, we used structural equation modeling as a powerful statistical method to examine hypertension risk factors. A conceptual model was proposed about relationships between risk factors of hypertension. The model suitability was confirmed with available information of 9704 participants in MA-SHAD study. Findings highlighted the value of direct and indirect effects and indicated that age, obesity and physical activity were the most influential factors on increasing blood pressure but physical activity had indirect effect on blood pressure. It appears that choosing a healthy lifestyle, including sufficient physical activity and preventing obesity are essential for prevention and management of hypertension.
