Association of ANRIL Gene Polymorphisms with Gastric Cancer Risk: A Case-Control Study.

Background: Gastric cancer's (GC) cause is unknown, but its complexity indicates that, in addition to environmental factors, it may have genetic origins. Scientists are studying single-nucleotide polymorphisms (SNPs) in the antisense noncoding RNA in the INK4 locus (ANRIL) gene, which encodes a long noncoding RNA molecule. They found a link between the ANRIL gene product and some polymorphisms and GC, suggesting genetic changes may lead to precancerous conditions. Methods: In a case-control research that included 250 patients with GC and 210 controls who were age- and gender-matched, four SNPs within the ANRIL gene were genotyped. These SNPs were rs1333049, rs496892, rs2383207, and rs2151280. Tetra-primer amplification refractory mutation system-PCR was utilized to carry out the process of genotyping. Results: It was found that the chance of developing GC was connected with three SNPs rs2151280, rs1333049, and rs496892. Nevertheless, rs2383207 did not demonstrate any meaningful connection. In addition, whereas CCTC and TTCC haplotypes were shown to be less common, certain haplotypes that contained these SNPs (TTCG, TCTC, and TTTC) displayed a considerably higher prevalence in the cancer group in comparison to the control group. Conclusion: This study showed novel associations between specific ANRIL gene polymorphisms (SNPs) and the risk of GC. These findings shed light on the potential role of ANRIL SNPs in GC risk and highlight the need for additional research to clarify the underlying functional processes. Understanding these functional processes might lead to developing novel diagnostic or treatment approaches for this cancer.

Age at menarche by birth cohort: A pooled analysis of half a million women in Asia.

OBJECTIVES: To evaluate changes in the age at menarche in Asian populations. STUDY DESIGN: Retrospective cohort study. METHODS: We included 548,830 women from six countries in Asia. The data were sourced from 20 cohorts participating in the Asia Cohort Consortium (ACC) and two additional cohort studies: Japan Multi-institutional Collaborative Cohorts (J-MICC), and Japan Nurse Health Study (JNHS) with data on age at menarche. Joinpoint regression was used to evaluate changes in age at menarche by birth year and by country. RESULTS: The study includes data from cohorts in six Asian countries namely, China, Iran, Japan, Korea, Malaysia and Singapore. Birth cohorts ranged from 1873 to 1995. The mean age of menarche was 14.0 years with a standard deviation (SD) of 1.4 years, ranged from 12.6 to 15.5 years. Over 100 years age at menarche showed an overall decrease in all six countries. China showed a mixed pattern of decrease, increase, and subsequent decrease from 1926 to 1960. Iran and Malaysia experienced a sharp decline between about 1985 and 1990, with APC values of -4.48 and -1.24, respectively, while Japan, South Korea, and Singapore exhibited a nearly linear decline since the 1980s, notably with an APC of -3.41 in Singapore from 1993 to 1995. CONCLUSIONS: Overall, we observed a declining age at menarche, while the pace of the change differed by country. Additional long-term observation is needed to examine the contributing factors of differences in trend across Asian countries. The study could serve as a tool to strengthen global health campaigns.

Effectiveness of long-term low-dose aspirin in the prevention of gastric cancer after Helicobacter pylori eradication: study design and rationale of Ardabil gastric cancer randomized placebo-controlled prevention trial (AGCPT).

BACKGROUND: In addition to Helicobacter pylori (H. pylori) infection eradication, some medications, including aspirin, metformin, and statins, have been suggested to have protective effects against gastric cancer (GC) development in observational studies. We launched the Ardabil gastric cancer randomized placebo-controlled prevention trial (AGCPT) to evaluate the effectiveness of long-term low-dose aspirin use for the prevention of development and mortality of GC after H. pylori eradication. METHODS/DESIGN: AGCPT is a prospective population-based double-blind, randomized clinical trial. The study sample was targeted at 21,000 participants aged from 35 to 70 years old, both sexes, in Ardabil, a province in northwest Iran with relatively high rates of GC incidence and mortality. All eligible participants were initially tested for H. pylori infection using a H. pylori stool antigen test. Participants with positive tests undergo H. pylori eradication by standard treatment regimens. All participants with a negative test and those with a positive test with a subsequent confirmed H. pylori eradication test were entered into the intervention phase. In the intervention phase, participants were allocated randomly into either the treatment (daily oral consumption of 81 mg enteric-coated aspirin tablets) arm or the control (placebo) arm using permuted balanced blocks. Subjects will be followed for an average period of 10 years to evaluate the incidence and mortality rates of GC. DISCUSSION: In addition to preventing other diseases like cardiovascular events, aspirin may prevent GC incidence and mortality. AGCPT will investigate the difference between the two study arms in the proportion of the cumulative incidence and mortality rates of GC. The study's results may help policymakers and researchers update the strategies for GC prevention. TRIAL REGISTRATION: This trial with the registry name of "The effect of Low-dose Aspirin in the Prevention of Gastric Cancer" was registered in the Iranian Registry of Clinical Trials, IRCT.ir, under the identifier IRCT201105082032N3. Registered on April 21, 2017.

The Effect of 131I Therapy on the Eradication of Helicobacter pylori in Patients with Thyroid Disorders: A Preliminary Study.

The leading cause of gastritis and its complications is Helicobacter pylori Radioactive iodine (131I) accumulates significantly in the stomach after consumption. On this basis, we decided to determine whether different doses of 131I in the stomach would be effective in eradicating the infection. Methods: All patients with hyperthyroidism or differentiated thyroid carcinoma who were referred for 131I treatment were invited to the study. A stool antigen test was conducted before consumption of 131I (0.15-5.5 GBq) and was repeated 2 mo later to detect H. pylori infection. Results: H. pylori positivity was found in 51.8% (14/27) of the patients. At 2 mo after treatment, 13 of the 14 patients with differentiated thyroid carcinoma or hyperthyroidism who had been identified as positive for H. pylori stool antigen before 131I administration were still positive, representing a nonsignificant eradication rate of 7.1%. Conclusion: Administration of 131I to patients with H. pylori did not show potential to eliminate the infection.

Combination of IFN-gamma with STING agonist and PD-1 immune checkpoint blockade: a potential immunotherapy for gastric cancer.

Suppression of the cGAS-STING pathway is an immune escape mechanism in cancer cells. The critical role of this pathway in gastric cancer (GC) is not fully understood. Herein, we evaluated the effect of the interferon-gamma (IFN-gamma), STING agonist, PD-1 immune checkpoint blockade, and their combination on the cGAS-STING pathway in GC. Expression of cGAS and STING in tumor tissue samples and adjacent normal tissue (ANT) biopsies of fifty new GC patients was evaluated by quantitative real-time PCR (qRT-PCR). Moreover, cGAS and STING expression levels were examined in Peripheral Blood Mononuclear Cells (PBMC) samples of forty GC patients and twenty-five healthy subjects. The apoptosis rate of cancer cells was analyzed by Annexin V-FITC/PI. Cell proliferation was measured by the BrdU assay. Also, IFN-ß levels were evaluated in the supernatants of the treated groups. The cGAS expression was decreased in patients with distant metastasis. Co-cultures treated with IFN-gamma showed an elevated level of cGAS and STING expressions in PBMC and cancer cells. The rate of apoptosis increased in all the treatment groups. In addition, the rate of proliferation in PBMCs increased in different treated groups. The main role of PBMCs in cytotoxicity was determined by a comparative analysis of the viability of cells treated with all treatments, both with and without PBMCs. The production of IFN-ß was elevated in all treated groups. The current study suggests that a combination therapy using IFN-gamma, STING agonist, and anti-PD-1 antibody can provide a promising approach to the treatment of GC.

Characteristics of suicide attempts in Northwestern Iran: a five-year population-based survey.

BACKGROUND: Suicide is a serious public health problem in the world. This study aims to describe the characteristics of suicide attempters in North-Western Iran and identify latent classes of suicide attempts. METHODS: This cross-sectional study was conducted in Ardabil Province (Northwest Iran) during 2017-2021 based on a registration system for suicide attempts. We performed latent class analysis (LCA) using a procedure for LCA (PROC LCA) in SAS to investigate the subgroups of suicide attempters based on their characteristics and method, history, and outcome of suicide. RESULTS: Three latent classes were identified for males and females; the first class (non-lethal attempters with lower educational levels) comprised 41.3% of males and 55.4% of females. The second class (non-lethal attempters with higher educational levels) described 52.4% of males and 42.7% of females. Finally, the third class (lethal attempters) included 6.4% of males and 1.9% of females. The main method of suicide attempts was poisoning with medications (87.3%). The results show that only 2.8% of people have a history of suicide attempts. Also, the suicide rate reached 8.26 per 100,000 population in 2021. CONCLUSION: The present study showed an increasing trend of suicide attempt incidence rate in Ardabil Province from 2017 (99.49 per 100,000 population) to 2021 (247.41 per 100,000 population). This means that the rate of change was 147.92 per 100,000 population during the study period. The findings of LCA, stress the necessity of identification and prioritization of unmet needs of people who had an incomplete suicide in Ardabil.

Risk of Gastric Cancer is Highly Dependent on Type of First-Degree Family Member Affected by Cancer: Lessons from a High-Risk Population in Iran.

Background: Family history of gastric cancer (GC) in first-degree relatives may increase the risk of GC. This study aimed to assess how family history of GC in first-degree relatives really affects the risk of GC in an extremely high-risk population. Methods: A large population-based case-control study was carried out on 1222 incident GC cases and 1235 controls in Ardabil Province-a high-risk area in North-West Iran-to assess the associations of GC family history in first-degree relatives with the risk of GC (2003-2017). Results: GC family history did not significantly associate with the risk of GC overall (ORadj=1.09, 95% CI: 0.80-1.47, P=0.589). It found no significant association of GC family history in a parent, and in a father, mother, and sister separately, with the risk of GC. However, GC risk was significantly associated with a history of GC in a sibling (ORadj=1.61, 95% CI: 1.11-2.35, P=0.013), especially brother (ORadj=2.24, 95% CI: 1.41-3.64, P=0.0008). The risk was greatly increased in subjects with two or more affected brothers (ORadj =5.56, 95% CI: 2.33-14.20, P=0.0002). Conclusion: We did not find a familial tendency to cardia GC and non-cardia GC as well as histopathologic features. Determining the type of first-degree relationships with GC may, therefore, be more important than assessing family history alone for predicting the risk of GC in this high-risk area.

Gastric troubles in Iran: The role of social and economic factors in Helicobacter pylori infection.

Background: Helicobacter pylori infection is a major risk factor for gastric cancer in Iran, but the impact of socioeconomic factors on its prevalence is poorly understood. This study aimed to assess the socioeconomic inequalities and risk factors associated with H. pylori infection in Iran. Methods: This cross-sectional study was conducted based on the PERSIAN cohort study. A total of 20460 individuals aged 35 to 70 years in Ardabil, Iran were included in the study. H. pylori infection was determined based on stool tests and clinical records. Multilevel logistic regression models with random intercepts at household and community levels were used to identify risk factors associated with H. pylori prevalence. The concentration index (CIn) and concentration curve (CC) were employed to assess socioeconomic-related inequality. Results: In this study, 70.4% (CI 69.6-71.0) of the participants were infected with H. pylori, with a higher prevalence in women (71.2%) than men (69.6%). Age (OR: 1.37, CI: 1.17-1.61), sex (OR: 1.20, CI: 1.12-1.28), level of education (OR: 1.33, CI: 1.17-1.49), cardiac disease (OR: 1.32, CI:1.18-1.46), and BMI groups (OR: 2.49, CI: 1.11-5.58) were significantly associated with H. pylori infection based on the multivariable logistic regression. The results of the CIn and CC indicated that H. pylori were more prevalent among economically disadvantaged groups (CIn: -0.1065; [-0.1374 to -0.0755]). Conclusion: The prevalence of H. pylori in Iran is higher than in other developing countries, and significant socioeconomic inequality exists between the poor and the rich. To reduce the rate of gastric cancer, socio-economic and demographic factors, especially the poor and people with low levels of education, should be considered.

Socioeconomic and environmental factors associated with waterpipe tobacco smoking among Iranian adults: a PERSIAN cohort-based cross-sectional study.

BACKGROUND: Waterpipe tobacco smoking (WTS) is associated with several deleterious health outcomes. We sought to estimate the prevalence of WTS and explore socioeconomic inequalities associated with this culturally-rooted tobacco smoking practice among Iranian adults. METHODS: A cross-sectional analysis was conducted among 20,460 adults (ages 18 and older) enrolled in the PERSIAN cohort study during 2020. Data were collected on socioeconomic status (SES), lifestyle, alcohol consumption, cigarette smoking, and several risk factors related to non-communicable diseases. The concentration curve and relative concentration index (RCI) were administered to assess and quantify the SES-based inequality in WTS. RESULTS: Overall age-adjusted prevalence of past-month WTS was 5.1% (95%CI:4.6-5.8), with about 1% for women and 10.6 for men. Age-adjusted prevalence of WTS was higher among younger adults, men, cigarette smokers, obese adults, and those with higher SES. The RCI estimation showed that WTS is more popular among adults with high income and education. WTS was higher among younger adults, cigarette smokers, obese adults, and those with higher SES. CONCLUSION: There is a clear socioeconomic inequality in WTS, with a higher prevalence among adults with higher income and education. The findings suggest the need for targeted interventions to address this inequality and reduce the prevalence of WTS among high-income communities.

Potential of macronutrients and probiotics to boost immunity in patients with SARS-COV-2: a narrative review.

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-COV-2) may cause inflammation and increased cytokine secretion. Dietary factors may play an important role in enhancing the immune responses against infectious diseases such as SARS-COV-2. This narrative review aims to determine the effectiveness of macronutrients and probiotics to improve immunity in SARS-COV-2 patients. Dietary proteins may boost pulmonary function in SARS-COV-2 patients through inhibitory effects on the Angiotensin-converting enzyme (ACE) and reduce Angiotensin (ANG-II). Moreover, omega-3 fatty acids may improve oxygenation, acidosis, and renal function. Dietary fiber may also produce anti-inflammatory effects by reducing the level of high-sensitivity C-Reactive Protein (hs-CRP), Interleukin (IL-6), and Tumor necrosis factor (TNF-α). In addition, some evidence indicates that probiotics significantly improve oxygen saturation which may enhance survival rate. In conclusion, the consumption of a healthy diet including adequate macronutrients and probiotic intake may decrease inflammation and oxidative stress. Following this dietary practice is likely to strengthen the immune system and have beneficial effects against SARS-COV-2.

Immunogenic Potential of the Mediterranean Fever Gene in Patients with Coronavirus Disease: A Cross-Sectional Study.

Background: In December 2019, an outbreak of pneumonia caused by the novel coronavirus disease 2019 (COVID-19) became a pandemic and caused a global health crisis. This study evaluates the immunogenic potential of the Mediterranean fever (MEFV) gene in patients with COVID-19. Methods: A cross-sectional study was conducted from March to April 2020 in various COVID-19 referral centers in Ardabil, Iran. Blood samples of 50 hospitalized patients with confirmed COVID-19 were evaluated for MEFV gene mutation using the amplification refractory mutation system polymerase chain reaction (ARMS-PCR) and Sanger sequencing. Statistical analysis was performed using SPSS software, version 22.0. Results: Mutations of the MEFV gene were found in 6 (12%) of the patients. All mutations were heterozygous, and no homozygous or compound heterozygous forms were detected. The total mutant allele frequency was 6% and the carrier rate was 12%. The most common allele of the MEFV variant was E148Q, detected in 3 (6%) patients. No mutant variant of the MEFV gene was detected in deceased patients. None of the mutation carriers had familial Mediterranean fever (FMF) symptoms or a family history of FMF. Conclusion: MEFV gene mutations may have immunogenic potential in patients with COVID-19.

Adult height and risk of gastric cancer: a pooled analysis within the Stomach cancer Pooling Project.

BACKGROUND: The association between height and risk of gastric cancer has been studied in several epidemiological studies with contrasting results. The aim of this study is to examine the association between adult height and gastric cancer within a large pooled analysis of case-control studies members of the Stomach cancer Pooling (StoP) Project consortium. METHODS: Data from 18 studies members of the StoP consortium were collected and analyzed. A multivariable logistic regression model was used to estimate the study-specific odds ratios (ORs) and 95% confidence intervals (CIs) for the association between 10-cm increase in height and risk of gastric cancer. Age, sex, tobacco smoking, alcohol consumption, social class, geographical area and Helicobacter pylori (H. pylori ) status were included in the regression model. Resulting estimates were then pooled with random-effect model. Analyses were conducted overall and in strata of selected variables. RESULTS: A total of 7562 cases and 19 033 controls were included in the analysis. The pooled OR was 0.96 (95% CI 0.87-1.05). A sensitivity analysis was performed restricting the results to the studies with information on H. pylori status, resulting in an OR of 0.97 (95% CI 0.79-1.20). CONCLUSION: Our study does not support a strong and consistent association between adult height and gastric cancer.

The effect of a web-based lifestyle intervention on nutritional status and physical activity on prevention of COVID-19: a randomized controlled trial in women's empowerment.

Background: Healthy dietary intake and physical activity affect the immune systems. The present study aimed to investigate the effects of a web-based lifestyle intervention on nutritional status, physical activity, and prevention of COVID-19. Methods: Three hundred-three women (30-60 years old), who did not have COVID-19 in the City of Ardabil, participated in this study. Participants were randomized into an intervention (n = 152) or control group (n = 151). The intervention group received eight online educational sessions focusing on a healthy diet and physical activity via the website. There was no educational session for the control group during the intervention, but they were placed on the waiting list to receive the intervention and given access to the website and educational content after the follow-up. Outcomes were nutritional status, physical activity, immunoglobulin G (IgG), and immunoglobulin M (Ig M) antibody titers against the virus. They were evaluated at the baseline, after 4 and 12 weeks. Results: Significant improvements in weight (P < 0.001), BMI (P < 0.001), total energy (P = 0.006), carbohydrate (P = 0.001), protein (P = 0.001), and fat (P < 0.001) were found for the intervention group compared to the control group during the study. MET-min/week for moderate physical activity increased during the time for the intervention and control groups (P < 0.001 and P = 0.007, respectively). MET-min/week for walking activity rose in the post-intervention and follow-up compared to that in the baseline in the groups (P < 0.001 for both groups). Total physical activity was increased during the study (P < 0.001) for both groups. The mean of serum IgG and IgM titers against the virus were increased during the study in both groups in time effect (P < 0.001). There was a significant time x group interaction for carbohydrate and fat intakes (P = 0.005 and P = 0.004, respectively). Conclusion: The web-based lifestyle intervention may improve nutritional status and physical activity, and have the potential to reduce the risk of contracting a COVID-19 infection.

Socio-economic inequality in prevalence of type 2 diabetes among adults in north-west of Iran: a Blinder-Oaxaca decomposition.

Background: The aim of this study was to estimate the socio-economic inequality in prevalence of type 2 diabetes among adults in north-west of Iran. Methods: A cross-sectional study was conducted in Ardabil with data from the PERSIAN Cohort Study. Diabetes has been measured by combining self-reported and clinical records. Based on the socio-economic status score, households divided into five quintiles. A multiple logistic regression model was used to examine the association between having diabetes and independent variables and the Blinder-Oaxaca (BO) method was used to decompose the socioeconomic inequality, respectively. Results: The Overall age-adjusted prevalence of diabetes among 20,419 Ardabil's adults was 14.3% (95% CI: 13.6 to 14.9). The prevalence of type 2 diabetes for the poorest and richest groups was 16.07% and 7.60%, the gap between the poorest and richest groups was 8.47%. The prevalence type 2 diabetes was significantly increasing with increasing in age (OR = 4.05, 95% CI = 3.27-5.02), BMI (OR: 3.10, 95%CI = 1.25-7.68), blood pressure (OR: 2.61, 95% CI = 2.37-2.88), and decreases with higher education level (OR = 0.78, 95% CI = 0.63-0.97). The richest-economic group has lower prevalence of diabetes (OR = 0.73, 95% CI = 0.60-0.88). The decomposition showed that most important factors affecting the difference between poorest and richest group in the prevalence of type 2 diabetes were age (86.1%), years of schooling (46.9%) and having chronic diseases such as hypertension (26.9%). Conclusions: The present study showed that the prevalence of type 2 diabetes was significantly higher among the elderly, women, uneducated, obese, and poor populations. Policies that address people poverty such as increasing job opportunities, increasing the minimum income etc. could reduce diabetes risk for poor people.

Efficacy of Addition of Atomoxetine to Speech Therapy in Stuttering Severity of Children Aged 4-12 Years: A Double-Blind Randomized Controlled Trial.

Objectives: Stuttering is a common problem at all ages that is required to be treated since childhood. Atomoxetine is currently used for the treatment of attention deficit hyperactivity disorder (ADHD). It can be effective for the treatment of stuttering due to its selective inhibition of norepinephrine reuptake and dopaminergic properties. Therefore, this randomized controlled trial aimed to evaluate the effect of atomoxetine on children's stuttering. Materials & Methods: The children aged 4-12 years and diagnosed with stuttering, referred to Pediatric Neurology and Psychology clinics , were randomly divided into experimental (n=50) and control (n=50) groups. One group received atomoxetine plus speech therapy, and the other group received only speech therapy. Both groups completed the Stuttering Severity Instrument-Fourth Edition at the baseline (on the first visit) and 3 months after the intervention. The results were compared between the two groups using SPSS software (version 21). Results: Most of the children (67%) were male. Moreover, 24%, 46%, and 30% of the subjects were within the age ranges of < 60, 60-95, and > 95 months, respectively. Nearly half of the patients (52%) had a positive family history of stuttering. Stuttering severity was the highest within the age range of 60-95 months, in left-handed children, in those who used formula, and in those who felt insecure in the family; however, there was no difference in stuttering severity based on child's gender, concomitant ADHD, multilingualism, facial or movement tics, sleeping hours, and using teats. The mean stuttering severity reduced in both groups (P<0.001), with a greater decrease in the experimental group, compared to that of the control group (P=0.011). Conclusion: Atomoxetine plus speech therapy is effective for the treatment of children's stuttering and can be used as a complementary treatment strategy in such patients.

Kidney stones among Iranian adults: Prevalence and socioeconomic inequality assessment in a cohort-based cross-sectional study.

Background and Aims: Kidney stone disease is a crystal concretion formed usually within the kidneys. The worldwide prevalence of kidney stones could be affected by numerous differences in socioeconomic, and environmental factors. The purpose of this study is to investigate kidney stones among Iranian adults aged between 35 and 70 years and the prevalence and evaluation of socioeconomic inequalities. Methods: In this, a cohort-based cross-sectional study was carried out among 20,427 participants of ArNCDs aged 35 and 70 years old. Kidney stone was defined as a dependent (and binary) variable while demographic and socioeconomic factors were considered independent variables. Multivariable logistic regression was used to identify the key socioeconomic factors affecting kidney stone prevalence in Ardabil. Results: The overall prevalence of kidney stones was 17.6 (95% confidence interval [CI]: 16.1-19.2) out of which 21.53% and 14.36% pertained to men and women and 14.18% and 23.17% pertained to the poorest and richest groups, respectively. There was a significant difference in the prevalence of kidney stones between men and women in terms of age, marital status, education level, chronic disease, body mass index, and socioeconomic status (<0.001). The prevalence of kidney stones had a positive correlation with age (1.7, 95% [CI]: 1.42-2.04) and socioeconomic status (1.5, 95% [CI]: 1.34-1.69), where the odds of kidney stones increased significantly by increasing age and socioeconomic status. Moreover, the kidney stone concentration index showed a pro-rich distribution wherein it was more common among wealthy people (higher socioeconomic status) 0.062 (95% [CI]: 0.051-0.072). Conclusion: The results of this study showed that there is significant inequality in the prevalence of kidney stones, where it was more common among the richest people. In addition, being men and old age are significantly related to kidney stones, so policymakers and physicians should consider these factors.

The Impact of Colchicine on COVID-19 patients: A Clinical Trial Study.

Background: Severe acute respiratory syndrome due to COVID-19 infection has evolved into a global pandemic. This study has been designed to evaluate colchicine as an anti-inflammatory agent among COVID-19 patients regarding the disease course, duration of hospitalisation, and its morbidity and mortality rate. Methods: This prospective randomised and double-blind clinical trial study included 100 COVID-19 hospitalized patients with moderate symptoms from May 21 to June 20, 2020. They were randomised in a 1:1 allocation to placebo and colchicine groups plus recommended standard guideline and protocol of health system. Colchicine 1 mg has been taken daily for 6 days. All data including associated symptoms, co-existed disease and duration of hospitalisation evaluated initially, and then 2 weeks after discharge; moreover, their mortality and morbidity, re-admission, and deteriorations of symptoms were assessed during this period. Results: 59% were female with median age 56 years old. There was no significant difference between them in terms of age and sex. Two groups did not show significant difference about underlying diseases and various clinical and para clinical findings evaluation. However, there were significant difference in colchicine group regarding for shorter duration of fever (P<0.05) and hospitalisation (P<0.05). Although in colchicine group dyspnoea improved more rapidly than the placebo group, it was not meaningful. Conclusion: Colchicine can be effective in amelioration of systemic symptoms and duration of hospitalisation probably by inhibition of inflammatory biomarkers in COVID-19 patients.

Socioeconomic inequalities in prevalence, awareness, treatment and control of hypertension: evidence from the PERSIAN cohort study.

BACKGROUND: Elevated blood pressure is associated with cardiovascular disease, stroke and chronic kidney disease. In this study, we examined the socioeconomic inequality and its related factors in prevalence, Awareness, Treatment and Control (ATC) of hypertension (HTN) in Iran. METHOD: The study used data from the recruitment phase of The Prospective Epidemiological Research Studies in IrAN (PERSIAN). A sample of 162,842 adults aged > = 35 years was analyzed. HTN was defined according to the Joint National Committee)JNC-7(. socioeconomic inequality was measured using concentration index (Cn) and curve. RESULTS: The mean age of participants was 49.38(SD = ± 9.14) years and 44.74% of the them were men. The prevalence of HTN in the total population was 22.3%(95% CI: 20.6%; 24.1%), and 18.8%(95% CI: 16.8%; 20.9%) and 25.2%(95% CI: 24.2%; 27.7%) in men and women, respectively. The percentage of awareness treatment and control among individuals with HTN were 77.5%(95% CI: 73.3%; 81.8%), 82.2%(95% CI: 70.2%; 81.6%) and 75.9%(95% CI: 70.2%; 81.6%), respectively. The Cn for prevalence of HTN was -0.084. Two factors, age (58.46%) and wealth (32.40%), contributed most to the socioeconomic inequality in the prevalence of HTN. CONCLUSION: The prevalence of HTN was higher among low-SES individuals, who also showed higher levels of awareness. However, treatment and control of HTN were more concentrated among those who had higher levels of SES, indicating that people at a higher risk of adverse event related to HTN (the low SES individuals) are not benefiting from the advantage of treatment and control of HTN. Such a gap between diagnosis (prevalence) and control (treatment and control) of HTN needs to be addressed by public health policymakers.

The socio-economic inequality in body mass index: a PERSIAN cohort-based cross-sectional study on 20,000 Iranian adults.

INTRODUCTION: The aim of the present study was to explore and determine the association between BMI and socio-economic factors in Iran. METHODS: Adults aged 35 to 70 (n = 20,460) were included from Ardabil Non-Communicable Disease (ArNCD) cohort study. BMI was calculated as kg/m2. Principal Component Analysis (PCA) was used to determine the socio-economic quintiles. Multivariate linear regression was performed to analyze the association of BMI as dependent variable with explanatory variables, Additionally, decomposition analyzing conducted to identify factors that explained wealth-related inequality in obesity. RESULTS: The prevalence of overweight and obese people was 83.7% (41.4% overweight and 42.5% obese) wherein the highest frequency of obese people belonged to the age group of 45 to 49 years old (19.9%) and to the illiterate people (33.1%). The results of multivariate linear regression model showed that age, being female, marriage, lower education level, having chronic disease, alcohol use, and higher socioeconomic level positively associated with obesity. The results of the decomposition model showed that the most important variables affecting socioeconomic inequality in higher BMI level were socioeconomic status (75.8%), being women (5.6%), education level (- 4.1%), and having chronic disease (2.4%). CONCLUSION: BMI showed significant association with socio-economic status, where richest people had significantly higher BMI than poorest group. Considering the direct role of high BMI in non-communicable diseases, new policies are needed to be developed and implemented by means of diet intervention and increased physical activity to control the BMI in the population of Iran.
