AbstractPrevious studies have shown the effect of refined grains on various cancers; however, data on the link between rice consumption and brain cancer are scarce. We aimed to investigate the relationship between rice consumption and glioma in Iranian adults. Current hospital-based case–control study was done in Tehran between 2009 and 2011. Cases were individuals with pathologically confirmed glioma in a maximally 1 month of the disease diagnosis (n = 128). Controls were individuals, aged between 20 and 75 years, who were hospitalized or were outpatients referred to other wards of the same hospital (n = 256). Cases and controls were frequently matched in terms of age and gender. Usual dietary intakes of participants, including rice consumption, during the preceding year were examined using a Block-format validated semi-quantitative 126-item food frequency questionnaire. Compared with participants in the lowest tertile of rice consumption (< 181 g/day), those in the highest tertile (≥ 279 g/day) had 2.47 times greater chance for having glioma (OR: 2.47, 95% CI 1.44–4.23). This relationship was also seen when potential confounders including demographic variables, energy and dietary intakes as well as body mass index were taking into account; such that individuals in the top tertile of rice consumption had 2.46 times greater odds of glioma compared with those in the bottom tertile (OR: 2.46, 95% CI 1.01–5.97). We found that rice consumption was positively associated with risk of glioma in adults. Further prospective studies are required to confirm this finding.

Abstract BackgroundMost of the studies regarding the relationship between socioeconomic status and occurrence of COVID-19 are usually ecological studies and have limitations due to ecological fallacy. The aim of this study is to investigate the relationship between socioeconomic status and individual-level risk of developing COVID-19.MethodsWe conducted a community-based, age and gender matched, case-control study in a district of Istanbul. The case group was defined as all confirmed COVID-19 cases (n=232) that were reported to the district health directorate in a week of August 2020. Control group was defined as people who were matched with cases in terms of age and gender and selected randomly from the directory of the same primary care provider in the district in 1:1 ratio. Participants were communicated via telephone. The socioeconomic status score was measured by Turkish Socioeconomic Status Index which considers three dimensions of it: education, occupation, and income.Results168 cases (72.4% response) and 168 controls are included in the study. 48.8% of participants are female and the mean age is 37.66±15.32 for each group. The mean socioeconomic status score is 70.28±7.09 for cases and 69.25±7.46 for controls (p=0.201). 15.2% (n=25) of cases and 22.4% (n=37) of controls is in lower socioeconomic status group (p=0.091). Neither bivariate nor logistic regression analysis revealed a statistically significant difference between study groups.ConclusionsOur findings indicate that socioeconomic status is not a significant predictor of COVID-19 occurrence at individual-level. The disease seems to be a common threat to all individuals of the global community.

Abstract Most of the studies investigating the relationship between socioeconomic status and the occurrence of COVID-19 have limitations due to their ecological design. To investigate the relationship between socioeconomic status and individual-level risk of developing COVID-19, we conducted a population-based, age and gender matched, case-control study in a district of Istanbul. The case group was defined as all confirmed COVID-19 cases (n=232) in the district in a week of August 2020. The control group was matched with cases in terms of age and gender and selected randomly from the directory of the same primary care provider in the district in a 1:1 ratio. The socioeconomic status was measured by the Turkish Socioeconomic Status Index which considers its three dimensions: education, occupation, and income. 168 cases (72.4% response) and 168 controls are included in the study. The mean socioeconomic status score is 70.28±7.09 for cases and 69.25±7.46 for controls (p=0.201). 15.2% (n=25) of cases and 22.4% (n=37) of controls is in lower socioeconomic status group (p=0.091). The analysis did not reveal a statistically significant difference between study groups. Socioeconomic status may not a significant predictor of COVID-19 occurrence at the individual-level. The disease seems to be a common threat to all individuals.

Introduction: It has been proposed that dietary intake is associated with multiple sclerosis (MS). The present case-control study was conducted to investigate the relationship between intake of different food groups and occurrence of MS among the recently diagnosed adult patients in Yazd City, Iran. Materials and Methods: In the current study, a group of 45 patients who have recently been diagnosed with MS and 100 healthy controls were investigated in this research. Participants were matched regarding their gender. Dietary intakes were assessed using a self-administered semi-quantitative food frequency questionnaire (FFQ). Participants also completed a demographic questionnaire including information such as age, gender, marital status, job, education, sun exposure, smoking, sunscreen, body mass index (BMI), economic status, as well as their spouses' occupations and education. Logistic regressions in crude and multivariable-adjusted models were used to investigate the relationship between food groups and the odds of developing MS. Results:  The findings showed that participants with high consumption of fruits, potatoes, refined grains, pickles, and fibers had a significantly lower chance for developing MS after adjustment for the maximum possible confounding variables (P < 0.05). Conclusion: The present study revealed that several food groups or nutrients are associated with the development of MS.  Further multi-central prospective studies including more participants are needed to confirm these results

Abstract Objective: The aim of this study was to explore the effects of NINJ2 polymorphisms on susceptibility of coronary heart disease (CHD).Methods: We conducted a case-control study with 499 CHD cases and 505 age- and sex- matched controls. Five single nucleotide polymorphisms (SNP) in NINJ2 (rs118050317, rs75750647, rs7307242, rs10849390 and rs11610368) were genotyped by Agena MassARRAY platform. Odd ratios (OR) and 95% confidence intervals (CI) were calculated using logistic regression to assess the association of NINJ2 polymorphism and CHD risk adjusting for age and gender..Results: NINJ2 rs118050317 significantly increased the risk of CHD in people over 60 years old (allele: P = 0.010; heterozygote: P = 0.016; dominant: P = 0.015; additive: P = 0.021) and women (allele: P = 0.026; heterozygote: P = 0.015; dominant: P = 0.018; additive: P = 0.030). Rs118050317 and rs7307242 were closely related to the risk of hypertension in CHD patients. Additionally, rs75750647 significantly increased diabetes risk in multiple models among CHD cases (allele: P = 0.014; homozygote: P = 0.037; heterozygote: P = 0.044; dominant: P = 0.019; additive: P = 0.013), whereas rs10849390 could protect CHD patients from diabetes in allele (P = 0.035), homozygote (P = 0.047) and additive (P = 0.037) models. We also observed two block (block 1: rs118050317 and rs75750647; block 2: rs7307242, rs10849390 and rs11610368) in NINJ2.Conclusion: Our results suggested that the relationships of NINJ2 polymorphisms and CHD risk were dependent on age, sex or complications.

Abstract Background:FGF23 controls serum l,25(OH)2D3 levels and phosphate homeostasis. This study evaluates the effects of Ferritin on intact PTH, FGF23 and l,25(OH)2D3 in patients with major thalassemia. It evaluates FGF23 changes in patients with hypoparathyroidism to clarify the interaction between FGF23 and PTH in the absence of proper PTH function in human. Methods:In this case-control study,25 patients with major-beta thalassemia with hypoparathyroidism and their age- and gender-matched patients with major-beta thalassemia having normal parathyroid function were enrolled. Biochemical studies assessed serum calcium, albumin phosphorus, alkaline phosphatase, PTH, FGF23, 25(OH)D, 1,25(OH)2D3, Ferritin and Fractional excretion of phosphorous. Results:FGF23 was higher in the patients with hypoparathyroidism compared to controls(p=0.002). Fractional excretion of phosphorous was lower in patients with hypoparathyroidism, despite of high FGF23(p=0.001). There was a correlation between serum1,25(OH)2D3 and FGF23 with ferritin in the controls(P=<0.001and P=<0.001,respectively). Conclusions: The present study suggested that rise in FGF23 in patients with thalassemia, may be due to either stimulating effect of PTH and 1,25(OH)2D3 on FGF23 production, or might be direct stimulating effect of ferritin. It seems that in hypoparathyroid patients with insufficient PTH action, the FGF23 is not able to exert its full function in reducing serum phosphorus level by its phosphaturic action.

Purpose Post-partum depression (PPD) is a mood disorder that affects 20-40 per cent of women in their post-delivery period worldwide. The purpose of this paper is to compare dietary intakes of energy, macronutrients, cholesterol, saturated fatty acids (SFAs), mono-unsaturated fatty acids (MUFAs), poly-unsaturated fatty acids (PUFAs), some micronutrients and antioxidants in PPD patients with healthy controls. Design/methodology/approach This case-control study was conducted on 163 women in postpartum period (81 PPD and 82 non-PPD) using Edinburgh questionnaire for the diagnosis of PPD. Dietary nutrients intake was assessed using 147-item semi-quantitative food frequency questionnaire (FFQ). Portion sizes of food items were converted to grams per day. Logistic regression models were used to estimate the association between tertiles of dietary intakes with the odds ratio (OR) of PPD. Findings According to the fully adjusted model, highest tertile compared to lowest tertile dietary intake of SFAs [OR = 0.01; 95 per cent confidence interval (CI) = 0.00, 0.01, p = 0.001], MUFAs (OR = 0.01; 95 per cent CI = 0.00, 0.02, p < 0.001), total fats (OR = 0.01; 95 per cent CI =0.00, 0.01, p < 0.001) and cholesterol (OR = 0.06 ; 95 per cent CI = 0.01, 0.08, p < 0.001), thiamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), riboflavin (OR = 0.10; 95 per cent CI = 0.02, 0.39, p < 0.001), pyridoxine (OR = 0.03; 95 per cent CI =0.01, 0.32, p < 0.001), folate (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), cobalamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001) , selenium (OR = 0.79 ; 95 per cent CI =1.36, 3.32, p < 0.001), iron (OR =0.68; 95 per cent CI = 0.24, 0.94, p < 0.001) and iodine (OR = 0.36; 95 per cent CI =1.10, 1.38, p < 0.001) had a protective effect on the incidence of PPD. Furthermore, higher intake of vitamin A and beta-cryptoxanthin can increase the incidence of PPD (OR =114.29; 95 per cent CI =17.85, 118.12, p < 0.001) and (OR = 4.85; 95 per cent CI = 1.49, 15.69, p = 0.015), respectively. Originality/value PPD may have destructive effects on the relationship between mother and infant. Results of previous studies demonstrated nutrients are required for the synthesis of neurotransmitters and have biochemical role in the nervous system.

Abstract Background & aim No study is available that explores the association of dietary phytochemical index (DPI) with glioma. The objective of the current study was to assess this association in Iranian adults. Methods This hospital-based case-control study included 128 newly-diagnosed cases of glioma and 256 age- and sex-matched controls. Data collection on dietary intakes was done using a 123-item validated food frequency questionnaire. Calculation of DPI was done as (dietary energy derived from phytochemical-rich foods (kcal)/total daily energy intake (kcal)) × 100. Logistic regression models were used to examine the association between DPI and glioma. Results Individuals in the top tertile of DPI were more likely to be older and female. Before taking potential confounders into account, subjects in the top tertile of DPI tended to have a 40% reduced chance of glioma than those in the bottom tertile (OR: 0.60; 95% CI: 0.35–1.02, P = 0.06). After controlling for age, sex, energy intake, several demographic variables and dietary intakes, the association between DPI and glioma became strengthened (OR: 0.43; 95% CI: 0.19–0.97, P = 0.04). Conclusion High intakes of phytochemical-rich foods were associated with a lower risk of glioma in adults. High consumption of phytochemical-rich foods might be recommended to prevent glioma. However, further studies with a prospective design are needed to confirm our findings.

Background. Circulating adiponectin has been suggested to be associated with atrial fibrillation (AF). However, whether the association differs by age and gender remains unknown. We performed a case-control study to evaluate the above association. Methods. AF patients who underwent 24-hour long-range 12-channel electrocardiogram examination at our center were included in this study, and people with normal sinus rhythm (NSR) were included as controls. All participants underwent echocardiography and heart rate variability tests. Biochemical parameters and adiponectin levels were also evaluated. Receiver operating characteristic (ROC) analyses were used to determine the predictive efficacy of adiponectin for AF, and multivariate logistic regression analysis was performed to evaluate the potential independent predictors of AF. Results. Overall, 84 patients with AF and 84 people with NSR were included. Serum adiponectin was significantly higher in AF patients compared to that in controls ( P < 0.001 ). ROC analysis showed that higher serum adiponectin (>6.098 μg/mL) had predictive efficacy for AF, with an area under the curve of 0.660 (95% confidence interval [CI]: 577–0.742). The results of multivariate logistic regression analysis showed that higher adiponectin was an independent predictor of AF in the overall participants (odds ratio [OR] 1.224, 95% CI 1.018–1.471, P = 0.032 ). Subgroup analysis showed that higher adiponectin was independently associated with AF in women (OR 1.893, 95% CI 1.160–3.089, P = 0.011 ) and in patients aged < 65 years (OR 1.453, 95% CI 1.023–2.064, P = 0.037 ), but not in men or those aged ≥ 65 years. Conclusions. Higher serum adiponectin level was independently associated with higher odds for AF in women and in participants <65 years old, but not in men or those aged ≥65 years.
