Assessment of Metabolic Risk Factors and Heart-Healthy Lifestyle in Atherosclerotic Coronary Artery Disease Patients Undergoing Percutaneous Coronary Intervention after a 6-Month Follow-Up.

Background: Mortality due to acute coronary syndrome (ACS) has dramatically diminished because of performing life-saving interventions. This study aims to assess the metabolic risk factors and heart healthy lifestyle following the first episode of ACS under percutaneous coronary intervention (PCI) treatment after the 6-month follow-up. Materials and Methods: This is a longitudinal study conducted on 40 patients who underwent PCI because of the first episode of ACS. The patients' information including age, weight, abdominal circumference, smoking, functional capacity, patients' metabolic equivalent of task (METS), and laboratory tests including triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), creatinine, fasting blood sugar (FBS), and hemoglobin A1C were recorded before discharge and reassessed after 6-month follow-up. Results: The patients were dominantly male (92.5%) with an average age of 56.8 ± 7.11 years. Physical activity and functional capacity (METS) significantly improved within 6 months (P = 0.019). BMI significantly improved; however, although the abdominal circumference decreased, it was not significant (P = 0.28). The number of smokers (P = 0.12) and the daily number of smoked cigarettes (P = 0.37) nonsignificantly decreased within 6 months. However, HDL-C (P = 0.013) and LDL-C (P = 0.027) changes were not desirable. TG, FBS, and blood pressure did not statistically significant change (P > 0.05). Conclusion: Although BMI, physical activity, and METS remarkably improved, waist circumference decreased nonsignificantly and lipid profile got worse paradoxically. Although this population is limited for generalization, this study shows that we require further schedules to improve ACS secondary prevention practice in our community.

Comparative Assessment of the Effects of Hydroxyethyl Starch and Normal Saline on Severe Hypotension in Patients with Aluminum Phosphide Poisoning: A Retrospective Study.

Background: Aluminum phosphide poisoning is one of the most common forms of poisoning which requires immediate and urgent treatment. Objective: This study aimed to compare the efficiency of two solutions, including hydroxyethyl starch and normal saline, in treating hypotension in patients with aluminum phosphide poisoning. Methods: This retrospective cohort study was conducted on 35 patients with aluminum phosphide poisoning. We reviewed the profile of 18 patients treated with hydroxyethyl starch and 17 patients treated with normal saline. Within-group and between-group differences in systolic blood pressure before and after treatment were compared using paired t-test and independent t-test, respectively. Results: The mean ± standard deviation (SD) age of the subjects in the starch and normal saline groups was 27.06 ± 9.72 and 27.88 ± 9.08, respectively. The levels of blood pressure in the two groups were not significantly different before the treatment; the mean ± SD of systolic blood pressure in the starch and normal saline groups was 72.67 ± 14.49 and 68.59 ± 8.3, respectively (P=0.313). After the treatment, it was significantly increased to 94 ± 24.45 and 85.18 ± 19.9 in the starch group (P=0.001) and the normal saline group (P=0.004), respectively. However, there was no significant difference between the two groups (P=0.245). Only one person survived in each group. Conclusion: According to the results of this study, although there was no significant difference between the two groups in terms of their effects on hypotension, these treatments could not prevent mortality.

Evaluation of correlation between digital vs. mercury sphygmomanometer in a middle-income country: The role of socio-economic situation.

BACKGROUND: Using manometer sphygmomanometers as standard measurement tool, there are controversial data regarding accuracy and validity of digital manometers for measurement of systolic (SBP) and diastolic blood pressure (DBP). Thus, we aimed to compare the accuracy of readings of digital sphygmomanometer in reference to mercury sphygmomanometer in a large population of healthy adults. METHODS AND MATERIALS: This cross-sectional study was performed on 1119 healthy adults. We measured participant's blood pressure once with mercury sphygmomanometer, as gold standard and again with digital mercury sphygmomanometer. Blood pressure was measured in sitting position after 5 min of rest and preferentially from right arm unless deformed. RESULTS: The mean ± standard deviation of age of participants was 37.25 ± 10.45 years. Majority of participants were male 588 (52.5%). The right/left SBP measured by digital sphygmomanometer were significantly higher compared with those measured by mercury sphygmomanometer: 115.37 ± 12.33 vs 110.95 ± 10.06/113.69 ± 11.77 vs 110.23 ± 10.34, respectively (P < .001), while an opposite result was observed about right/left DBP: 68.60 ± 8.55 vs 70.60 ± 8.31/69.39 ± 8.31 vs 70.75 ± 8.41, respectively (P < .001). In subgroup analysis in terms of marital status, education, and income, we observed similar findings. CONCLUSION: According to the results of our data analysis, it was shown that the digital device measurements had significant incompatibility with the mercury sphygmomanometers and it seems that digital devices still cannot be used as the gold standard in blood pressure measurement.

A paradoxical change in economic inequality in presenting visual acuity between 2009 and 2014: a nonuseful decline.

BACKGROUND: Despite the widespread literate on health inequalities and their determinants, changes in health inequalities over time have not received enough attention. AIMS: To measure and decompose the over-time changes in economic inequality in presenting visual acuity measured using Logarithm of the Minimum Angle of Resolution. METHODS: We analysed 4706 participants who had complete data on presenting visual acuity and economic status in 2009 and 2014 in the Shahroud Eye Cohort Study. We measured changes in presenting visual acuity concentration indices and decomposed them the using a longitudinal approach. RESULTS: Both the presenting visual acuity and economic status deteriorated between 2009 and 2014. The mean (standard deviation) for presenting visual acuity and economic status scores in 2009 versus 2014 were 0.090 (0.2) versus 0.103 (0.2) and 0.01 (1.0) versus 0.0005 (1.07), respectively. Presenting visual acuity concentration index (95% confidence interval) in the first versus second phases of the study were -0.245 (-0.212 to -0.278) versus -0.195 (-0.165 to -0.225), respectively. Longitudinal decomposition of this change in concentration indices during the 5-year period indicated that the most important contributor to reduction in economic inequality of presenting visual acuity was deterioration of presenting visual acuity among people with higher economic status due to their ageing. CONCLUSION: Unexpectedly, reduction in economic inequality in presenting visual acuity was due to presenting visual acuity deterioration among the higher economic status group rather than its amelioration among the lower economic status group. Therefore, the needs of all socioeconomic groups should be considered separately to modify presenting visual acuity in each group and, consequently, reduce the economic inequality in presenting visual acuity.

Decomposing educational inequality in maternal mortality in Iran.

Given the significance of educational equality as one of the key social determinants of health in maternal health outcomes, the present study aimed to assess maternal mortality inequality and its main contributors based on the level of education amongst mothers living in Isfahan, Iran. In this case-control study, all 171 maternal deaths in the Isfahan Province during 2001-2016 were taken from the national maternal mortality surveillance system (as a case group). For the control group, 523 mothers who were alive were selected from 22 health centers located in 21 cities in the province of Isfahan. Concentration index and curve were used to measure educational inequality in maternal mortality. The chi-square test was used to select explanatory social and health variables to enter the decomposition model. The analyses were performed with STATA 12. Social and healthcare factors accounted for 43.57% and 23.44% of educational inequality, respectively. The normalized maternal mortality concentration index was -0.13 (95% CI, -0.10 to -0.02). Among the social factors, the mother's education level (38.14%) and immigrant status (25.39%) contributed the most to educational inequality. Regarding healthcare factors, proximate medical causes (14.49%) and the number of pregnancies (9.72%) had the highest contribution. Maternal mortality has been distributed unequally among the less and more educated mothers in Iran, which suggests that promoting health literacy is imperative, especially for women with lower education levels.

Income-related inequality in completed suicide across the provinces of Iran.

OBJECTIVES: The aim of this study was to measure income-related inequality in completed suicide across the provinces of Iran. METHODS: This ecological study was performed using data from the Urban and Rural Household Income and Expenditure Survey-2010 conducted by the Iranian Center of Statistics, along with data on completed suicide from the Iranian Legal Medicine Organization in 2012. We calculated the Gini coefficient of per capita income and the completed suicide rate, as well as the concentration index for per capita income inequality in completed suicide, across the provinces of Iran. RESULTS: The Gini coefficients of per capita income and the completed suicide rate in the provinces of Iran were 0.10 (95% confidence interval [CI], 0.06 to 0.13) and 0.34 (95% CI, 0.21 to 0.46), respectively. We found a trivial decreasing trend in the completed suicide incidence rate according to income quintile. The poorest-to-richest ratio in the completed suicide rate was 2.01 (95% CI, 1.26 to 3.22). The concentration index of completed suicide in the provinces of Iran was -0.12 (95% CI, -0.30 to 0.06). CONCLUSIONS: This study found that lower income might be considered as a risk factor for completed suicide. Nonetheless, further individual studies incorporating multivariable analysis and repeated cross-sectional data would allow a more fine-grained analysis of this phenomenon.

Economic Inequality in Presenting Vision in Shahroud, Iran: Two Decomposition Methods.

BACKGROUND: Visual acuity, like many other health-related problems, does not have an equal distribution in terms of socio-economic factors. We conducted this study to estimate and decompose economic inequality in presenting visual acuity using two methods and to compare their results in a population aged 40-64 years in Shahroud, Iran. METHODS: The data of 5188 participants in the first phase of the Shahroud Cohort Eye Study, performed in 2009, were used for this study. Our outcome variable was presenting vision acuity (PVA) that was measured using LogMAR (logarithm of the minimum angle of resolution). The living standard variable used for estimation of inequality was the economic status and was constructed by principal component analysis on home assets. Inequality indices were concentration index and the gap between low and high economic groups. We decomposed these indices by the concentration index and BlinderOaxaca decomposition approaches respectively and compared the results. RESULTS: The concentration index of PVA was -0.245 (95% CI: -0.278, -0.212). The PVA gap between groups with a high and low economic status was 0.0705 and was in favor of the high economic group. Education, economic status, and age were the most important contributors of inequality in both concentration index and Blinder-Oaxaca decomposition. Percent contribution of these three factors in the concentration index and Blinder-Oaxaca decomposition was 41.1% vs. 43.4%, 25.4% vs. 19.1% and 15.2% vs. 16.2%, respectively. Other factors including gender, marital status, employment status and diabetes had minor contributions. CONCLUSION: This study showed that individuals with poorer visual acuity were more concentrated among people with a lower economic status. The main contributors of this inequality were similar in concentration index and Blinder-Oaxaca decomposition. So, it can be concluded that setting appropriate interventions to promote the literacy and income level in people with low economic status, formulating policies to address economic problems in the elderly, and paying more attention to their vision problems can help to alleviate economic inequality in visual acuity.
