A large population-based study on the prevalence of electrocardiographic abnormalities: A result of Mashhad stroke and heart atherosclerotic disorder cohort study.

BACKGROUND: Twelve-lead electrocardiogram (ECG) is a common and inexpensive tool for the diagnostic workup of patients with suspected cardiovascular disease, both in clinical and epidemiological settings. The present study was designed to evaluate ECG abnormalities in Mashhad population. METHODS: ECGs were taken as part of MASHAD cohort study (phase1) and were coded according to the Minnesota coding criteria. Data were analyzed using SPSS. RESULTS: Total 9035 ECGs were available for final analysis including 3615 (40.0%) male and 5420 (60.0%) female. Among ECG abnormalities precordial Q wave, major T-wave abnormalities, inferior Q wave, sinus bradycardia, and left axis deviation were the most prevalent abnormalities. The frequency of precordial and inferior Q wave, inferior QS pattern, major and minor ST abnormalities, major and minor T abnormalities, Wolff-Parkinson-White and Brugada pattern, sinus bradycardia, sinus tachycardia, left axis deviation, ST elevation, and tall T wave were significantly different between two genders. Moreover, the frequency of Q wave in precordial and aVL leads, QS pattern in precordial and inferior leads, major and minor T-wave abnormalities, Wolff-Parkinson-White, atrial fibrillation, sinus bradycardia, left axis deviation, and ST elevation were significantly different in different age groups. A comparison of the heart rate, P-wave duration, and QRS duration between men and women indicated that there was a significant difference. CONCLUSIONS: Our finding indicated that the prevalence ECG abnormalities are different between men and women and also it varied in different age groups.

Adherence to the nordic diet is associated with anxiety, stress, and depression in recovered COVID-19 patients, a case-control study.

BACKGROUND: Follow-up of COVID-19 recovered patients to discover important adverse effects on other organs is required. The psychological health of COVID-19 patients may be affected after recovery. AIM: We aimed to evaluate the association between adherence to the Nordic diet (ND) and psychological symptoms caused by COVID-19 after recovery. METHOD: Dietary data on 246 qualified adults (123 cases and 123 controls). The dietary intake in this case-control study was calculated by a reliable and valid food frequency questionnaire (FFQ). Depression Anxiety Stress Scale (DASS), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Short-Form Health Survey (SF-36) were used to analyze participant's anxiety, stress, depression, sleep quality, insomnia, and quality of life of participants. RESULTS: There was a significant inverse relationship between total anxiety, stress, and depression scores and the intake of whole grains (P < 0.05). Furthermore, there was a significant inverse association between depression and fruit intake (P < 0.05). A significant negative correlation was found between insomnia and sleep quality and the intake of root vegetables (P < 0.05). In the multinomial-regression model, a significant association between the Nordic diet and anxiety, stress, and depression was found only in the case group (OR = 0.719, 95% CI 0.563-0.918, p-value = 0.008; OR = 0.755, 95% CI 0.609-0.934, P-value = 0.010, and, OR = 0.759, 95% CI 0.602-0.956, P-value = 0.019 respectively). CONCLUSION: Adherence to the Nordic diet might reduce anxiety, stress, and depression in recovered COVID-19 patients.

Adherence to dietary approaches to stop hypertension (DASH) diet in relation to psychological function in recovered COVID-19 patients: a case-control study.

BACKGROUND: Follow-up of patients after recovery from coronavirus disease 2019 (COVID-19) and identifying the adverse effects of the disease in other organs is necessary. Psychiatric symptoms can persist after patients recover from the infection. AIM: We aimed to examine the adherence to the dietary approach to stop hypertension (DASH) diet in relation to psychological function in individuals who have recovered from COVID-19. METHOD: This case-control study was conducted on 246 eligible adults (123 cases and 123 controls). A valid and reliable food frequency questionnaire (FFQ) was used to determine dietary intake. Depression, anxiety and stress, insomnia, sleep quality, and quality of life of participants were evaluated using DASS, Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and SF-36 questionnaires, respectively. RESULTS: There was a significant inverse correlation between total depression score with vegetables, depression, anxiety, and stress score and dietary intake of nuts, legumes, and whole grains (p < 0.05). There was a significant positive correlation between stress scores and the intake of red and processed meat (P < 0.05). In multivariate-adjusted regression model, a significant association was found between adherence to DASH diet and depression and stress only in case group (OR = 0.7863, 95% CI 0.746-0.997, p = 0.046 and OR = 0.876, 95% CI 0.771-0.995, p = 0.042, respectively). CONCLUSION: Adherence to a DASH diet might be associated with depression and stress reduction in recovered COVID-19 patients.
