Introduction: Recent studies have shown that Polyunsaturated Fatty Acids (PUFAs), including Eicosapentaenoic Acid (EPA), and Arachidonic Acid (AA), are associated with cognitive functions in patients with Coronary Artery Disease (CAD). Nevertheless, controversial results have been reported, too. The current study aimed to clarify the association of serum EPA and AA levels with cognitive decline in an Iranian sample with CAD. Methods: We evaluated cognitive function with the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA), in relation to serum levels of EPA and AA, in 179 CAD patients. The associations between the MMSE and MoCA scores and the other demographic parameters were evaluated. Results: Patients with CAD generally had mild cognitive impairment. But we could not find any significant correlation between PUFAs and cognitive function. However, BMI was associated with EPA/MoCA; age was associated with MMSE/MoCA and BMI. Finally, the correlation between sex and MMSE/MoCA was significant. Conclusion: Subjects generally had mild cognitive impairment, but we could not find any significant correlation between serum EPA and AA levels with cognitive function.

Objective Based on the few population-based studies that have been conducted in the Middle East, we determined the incidence of stroke in Qom, one of the central provinces of Iran. Methods The Qom province includes an estimated at-risk population of about 1 million. During a 12-month period (November 2018–November 2019), all first-ever strokes occurring in the target population were registered. Hospitalized cases were ascertained by discharge codes. Out-of-hospital cases were ascertained by a prospective screening of emergency medical services, emergency departments, ambulances records, primary care clinics, rural and urban public health centers, primary care physician offices, and neurologists’ offices. Crude and age-adjusted incidence rates (per 100,000 person-years) were calculated. Results During the study period, 1462 first-ever strokes occurred with a mean age of 68.1 (17–103) years; of these 45.2% were females (661 cases). The crude annual incidence rate per 100,000 at-risk populations was 145.4 (95% confidence interval, 138.1–153.0) for all types of stroke (156.5 for males and 134.3 for females), 26.4 (95% confidence interval, 23.5–29.8) for hemorrhagic stroke, and 114 (95% confidence interval, 105–121) for ischemic stroke. The incidence rate adjusted to the world population was 201.4 (95% confidence interval, 193–210) per 100,000 at-risk populations (adj incidence, 218.5 for males vs 187.4 for females). The total fatality rate during the first 28 days was 19.6%. Conclusion This study states that in this region there is a high incidence of stroke, which occurs at a younger age than the global average. There was a high prevalence of underlying stroke risk factors.

Objective: To evaluate the level of inflammatory factors of erythrocyte sedimentation rate and reactive protein C in benign and malignant thyroid nodules. Material and Methods: In this case-control study, patients who were referred because of an enlarged thyroid gland were selected, patients who had undergone surgery for the thyroid nodule were included in the study. Erythrocyte sedimentation rate and reactive protein C were measured before surgery in patients who were candidates for thyroid surgery. The histopathological records of patients were retrospectively reviewed. Relevant cases had a cytological evaluation of thyroid nodules by fine-needle aspiration cytology (FNAC) . The mean of ESR / CRP in both groups was compared using an independent t-test (p>0.05). Results: In malignant tumor type, in all patients, with Pill (PTC), analyzes in the malignant group showed a significant difference between the mean ESR / CRP in both groups with and without thyroid history. Sub-analyzes in the malignant group were significantly different between the mean ESR / CRP in both groups with and without thyroid histories (p=0.009) (40.16 ± 28.81). The association between ESR and CRP, ESR / CRP and tumor size, ESR / CRP and age in each group as well as in the whole patients were evaluated using Pearson correlation test, which showed a positive association between ESR age and ESR (p=0.024, r=0.375). In the malignant group, a negative correlation was found between the age and the CRP rate (p=0.027, r=-0.441), and in the total patients between the age and the rate (ES=0.043, r=-0.256) . Conclusion: Factors such as ESR and CRP, which are considered acute phase reactors and their levels increase in acute inflammatory conditions, may not have a significant increase in chronic inflammatory conditions and malignancies.

BACKGROUND Autoimmune rheumatic disorders are a group of illnesses that significantly affect pregnancy outcomes. AIM The aim of this study was to evaluate the incidence and risk factors of spontaneous abortion and its association with maternal medical care in women with autoimmune rheumatic diseases. METHODS In this medical record review study, we recruited patients who were referred to our clinic from September 2014 to September 2019. All confirmed pregnancies (based on a positive pregnancy test and sonogram) were included. Binary logistic regression was applied to construct the statistical model. FINDINGS The present study involved 97 women (215 total confirmed pregnancies) who were diagnosed with 7 different autoimmune rheumatic disorders. The rate of spontaneous abortion was 28.8%. In the univariate analysis, the preconception obstetrics and rheumatology consultation were negatively associated with spontaneous abortion (p < 0.001; odds ratio [OR], 0.255; 95% confidence interval [CI], 0.136-0.480; and p < 0.001; OR, 0.042; 95% CI, 0.015-0.122, respectively). Perinatal obstetric care had a significant protective effect (p < 0.001; OR, 0.260; 95% CI, 0.139-0.486). The multivariate analysis showed that the preconception rheumatology consultation (p = 0.003; OR, 0.062; 95% CI, 0.010-0.393) was negatively associated with spontaneous abortions. The presence of active diseases before pregnancy (p = 0.005; OR, 9.978; 95% CI, 2.023-49.223), anti-SSA/Ro (p < 0.001; OR, 22.927; 95% CI, 4.921-106.818), and anticardiolipin IgM (p = 0.004; OR, 298.207; 95% CI, 6.209-14,323.037) were associated with a heightened risk of spontaneous abortion. CONCLUSIONS A collaborative work carried out by maternal-fetal medicine specialists and rheumatologists could remarkably improve pregnancy outcomes.

Objectives Traffic noise, as one of the noise types, is a widespread feature of the urban environments. Traffic noise exposure can lead to hearing loss, hypertension, obesity and ischemic heart diseases. Thyroid hormones involved in the physiological and pathological conditions of the body. Therefore, this study was designed to aim the evaluation of traffic noise effects on thyroid hormones secretion and thyroid tissue structure. Methods Seventy two males and females wistar rats were used in this study. After one week adaptation, they divided randomly into 12 groups; the control, short term (one day) and long term (one, two, three and four weeks) groups. Traffic sound was recorded, adjusted and played (86 dB) for animals. Female rats’ cycle estrus was matched. At the end of experiment, the animals were anesthetized and cardiac blood sample was drawn. Thyroid tissue was then removed. Levels of the T3, T4, TSH, corticosterone and H&E staining were measured. p Results Findings showed that in the one-day group, T3 levels increased and T3 levels decreased in the long term groups (p Conclusions This study revealed that traffic noise exposure led to increase of T3 plasma concentration and decrement of TSH level, although in the long term, they return to basal status. It may be due to adaptation to traffic noise.
