Impact of Performing Health Promotion Model Intervention on Physical Activity of Health Volunteer of Torbat-e-Jam City, Iran
Abstract Aims: Regular physical activity can reduce the burden of chronic diseases, such as heart disease, diabetes, and some cancers, and can prevent early death. This study examined the impact of performing health promotion model intervention on physical activity of the health volunteers. Materials & Methods: This cross-sectional research is part of a three-month Intervening study started in 2015 on 80 health volunteers in Torbat-e Jaam City, Iran, which was selected by multistage random sampling method and participants were divided into two interventional and control groups. A Demographic Questionnaire and The Persian version of International Physical Activity Questionnaire were used to collect data. The data was analyzed in SPSS 16 using independent T, Pearson's correlation coefficient and linear regression tests. Findings: Before the intervention the mean of perceived benefit score was 31.3±4.5 that was evaluated as “good” but self-efficacy and behavior scores were 5.8±4.1 and 912.4±750.8 that were assessed as “poor”. Physical activity had positive correlation with perceived benefits, self-efficacy, commitment, positive, emotion and situational influences and a negative correlation with perceived barriers. Overall 66.8 of the physical activity was predicted by Pender’s Health Promotion Model variables. There was a significant difference between the mean scores of physical activity and other structures of HPM in the experimental group after the intervention and its score before intervention. Conclusion: Educational program based on Pender's health promotion model is effective in improving physical activity of health volunteers
Assessing the Physical Activity of Health Volunteers Based on the Pender's Health Promotion Model
Abstract Aims: Physical inactivity has been identified as the 4th leading risk factor for global mortality causing an estimated of 3.2million deaths per year. This study aimed to assess the physical activity of health volunteers with Pender's Health Promotion Model. Instrument & Methods: This cross-sectional analytical study was performed on 80 health volunteers in Torbat-e-Jam City, Iran, in 2015. A researcher-made questionnaire with the following sections was used to gather data; perceived benefits, perceived barriers, self-efficacy, interpersonal influences, positive emotion, commitment, modeling and competing preferences. SPSS 16 sofware was used to analyze data by independent T, Pearson's correlation coefficient and linear regression tests. Findings: There was no significant difference between the scores according to educational levels, age groups, BMI score, marital status, habitat and experience as a health volunteer duration. Physical activity had positive correlation with perceived benefits, self-efficacy, commitment, positive emotion and situational influences and a negative correlation with perceived barriers. Situational influences, as the strongest predictor of the physical activity, predicted 35.1 of it and then positive emotions predicted 34.7 and self-efficacy predicted 23.4 of physical activity. Conclusion: The level of physical activity in health volunteers of Torbat-e-Jam City, Iran, is not appropriate and is less than moderate
Combination of gastric atrophy, reflux symptoms and histological subtype indicates two distinct aetiologies of gatric cardia cancer.
<b>INTRODUCTION</b>
Atrophic gastritis is a risk factor for non-cardia gastric cancer, and gastro-oesophageal reflux
disease (GORD) for oesophageal adenocarcinoma. The role of atrophic gastritis and GORD in the
aetiology of adenocarcinoma of the cardia remains unclear. We have investigated the association
between adenocarcinoma of the different regions of the upper gastrointestinal tract and atrophic
gastritis and GORD symptoms.
<b>METHODS</b>
138 patients with upper GI adenocarcinoma and age and sex matched controls were studied.
Serum pepsinogen I/II was used as a marker of atrophic gastritis and categorised to five quintiles.
History of GORD symptoms, smoking and H.pylori infection was incorporated in logistic regression
analysis. Lauren classification of gastric cancer was used to subtype gastric and oesophageal
adenocarcinoma.
<b>RESULTS</b>
Non-cardia cancer was associated with atrophic gastritis but not with GORD symptoms; 55% of
these cancers were intestinal subtype. Oesophageal adenocarcinoma was associated with GORD
symptoms, but not with atrophic gastritis; 84% were intestinal subtype. Cardia cancer was positively
associated with both severe gastric atrophy [OR, 95% CI: 3.92 (1.77 – 8.67)] and with frequent
GORD symptoms [OR, 95% CI: 10.08 (2.29 – 44.36)] though the latter was only apparent in the nonatrophic
subgroup and in the intestinal subtype. The association of cardia cancer with atrophy was
stronger for the diffuse versus intestinal subtype and this was the converse of the association
observed with non-cardia cancer.
<b>CONCLUSION</b>
These findings indicate two distinct aetiologies of cardia cancer, one arising from severe atrophic
gastritis and being of intestinal or diffuse subtype similar to non-cardia cancer, and one related to
GORD and intestinal in subtype, similar to oesophageal adenocarcinoma. Gastric atrophy, GORD
symptoms and histological subtype may distinguish between gastric versus oesophageal origin of
cardia cancer
Mutation analysis of KRAS and BRAF genes in metastatic colorectal cancer: A first large scale study from Iran
Background: The investigation of mutation patterns in oncogenes potentially can make available a reliable mechanism for management and treatment decisions for patients with colorectal cancer (CRC). This study concerns the rate of KRAS and BRAF genes mutations in Iranian metastatic colorectal cancer (mCRC) patients, as well as associations of genotypes with clinicopathological features. Materials and Methods: A total of 1,000 mCRC specimens collected from 2008 to 2012 that referred to the Mehr Hospital and Partolab center, Tehran, Iran enrolled in this cross sectional study. Using HRM, Dxs Therascreen and Pyrosequencing methods, we analyzed the mutational status of KRAS and BRAF genes in these. Results: KRAS mutations were present in 33.6 cases (n=336). Of KRAS mutation positive cases, 85.1 were in codon 12 and 14.9 were in codon 13. The most frequent mutation at KRAS codon 12 was Gly12Asp; BRAF mutations were not found in any mCRC patients (n=242). In addition, we observed a strong correlation of KRAS mutations with some clinicopathological characteristics. Conclusions: KRAS mutations are frequent in mCRCs while presence of BRAF mutations in these patients is rare. Moreover, associations of KRAS genotypes with non-mucinous adenocarcinoma and depth of invasion (pT3) were remarkable
The Effect Of Probiotic Supplement To Reduce Abdominal Bloating In Stroke Patients Admitted To The ICU
Background: Bloating, is a common complication in patients with stroke; that increased intracranial pressure due to cerebral hypoxia in these patients. Most drugs have adverse effects to relieve flatulence.So this study aimed to investigate the effect of synbiotic supplement on stroke patients; was performed.
Methods: The study, on 65 stroke patients; was done. They were randomly divided into two groups: control (n = 32) and intervention (n = 33) and the size of their abdominal circumference were measured before the study. The intervention group, in addition to routine treatment, for a week, every 12 hours, recived fermented prbiotic supplement Zhari Takhmir and the control group was given only a laxative( MOM = 15cc) prescribed by a doctor. In the end, abdominal circumference in all patients were evaluated again. Data using analysis of covariance model, were analyzed .
Results: After a week, abdominal circumference measurements in two groups showed that; in the intervention group on average waist size of 6.1 inches had reduced compared to baseline( p=0.028). But the changes were not significant in the control group.
Conclusion: The study showed that a probiotic supplementation reduces abdominal circumference and distention in patients with stroke; Therefore, probiotics can be used as a non-drug therapy in the treatment of these patients
Spatial distribution and health risk of exposure to BTEX in urban area: a comparison study of different land-use types and traffic volumes
Many previous studies have investigated BTEX concentrations in urban areas; however, the available evidence on the association of different land-use types and BTEX concentrations is still scarce. In this study, the BTEX concentrations were measured and compared in different land-use types and traffic volumes of Mashhad metropolis, Iran. Sampling was conducted in summer and winter of 2018 based on NIOSH 1501 method in six land-use types, including Residential, Commercial/official, Industrial, Greenspace, Transportation, and Tourism. The spatial autocorrelation model was used to investigate the emission pattern. The Monte Carlo simulation technique and sensitivity analysis were used to assess the health risk of exposure to BTEX compounds. The median interquartile range (IQR) of benzene, toluene, ethylbenzene m-xylene, o-xylene and total BTEX concentrations based on overall mean were 4 (2.23), 8.37 (4.48), 1.2 (1.46), 0.89 (2.59), 0.8 (1.73) and 17.7 (8.19) µg/m3, respectively. Benzene and toluene had clustered emission patterns (z-score > 1.96). Exposure to benzene in the study area had a carcinogenic risk for inhabitants. The concentration of BTEX compounds was significantly different based on land-use type. The maximum and minimum concentrations of BTEX were observed in Transportation and Greenspace land uses, respectively. The BTEX concentrations in summer were significantly higher than in winter, and traffic had a significant effect on BTEX concentrations. Overall, our results supported a significant relationship between land-use type and BTEX concentrations in the urban area. Moreover, ambient benzene concentration had a carcinogenic risk potential for inhabitants of study area. © 2021, The Author(s), under exclusive licence to Springer Nature B.V. part of Springer Nature
Polymorphism of IL-28B gene (rs12979860) in HCV genotype 1 patients treated by pegylated Interferon and Ribavirin
Background: Nowadays, the immune response to hepatitis C (HCV) treatment has become a crucial issue mostly due to the interleukin 28B (IL-28B) polymorphism effects in chronic HCV patients. The aim of this study was to detect the polymorphism of IL-28B gene (rs12979860) in HCV genotype 1 patients treated with pegylated Interferon and Ribavirin. Methods: From the 2010 to 2012, a total of 115 peripheral blood mononuclear cells (PBMCs) of HCV patients who presented to Gastrointestinal & Liver Disease Research Center (GILDRC), Firoozgar Hospital, Tehran, Iran were enrolled in this retrospective cross sectional study. Samples were then categorized based on the presence of sustained virologic response (SVR and no-SVR). Variables including age, gender, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels of the two groups were investigated based on different IL-28B genotypes. Results: Analysis by the variables of age and gender showed a mean age ± SD of 42.1±14.0 and gender variability of 44 females (38.2) and 71 males (61.8). Adding up these results, the analysis of ALT levels revealed that there was between 293 and 14 mg/ml; AST levels ranged between 217 and 17 mg/ml; the viral load (HCV RNA) ranged between 7,822,000 and 50 IU/ml; the prevalence of CC, CT and TT genotypes were 90.9, 54 and 25.0. Conclusion: IL-28B polymorphism has an effective impact on the therapeutic response to ribavirin and peginterferon combination therapy in chronic HCV patients infected by different genotypes. This polymorphism is crucial in natural clearance. © 2016, Iran J Pathol. All rights reserved
