People with epilepsy (PWE) are neither more likely to be infected by the coronavirus nor are they more likely to have severe COVID-19 manifestations because they suffer from epilepsy. However, management of COVID-19 in PWE may be more complicated than that in other individuals. Drug-drug interactions could pose significant challenges and cardiac, hepatic, or renal problems, which may happen in patients with severe COVID-19, may require adjustment to antiepileptic drugs (AEDs). In this review, we first summarize the potential drug-drug interactions between AEDs and drugs currently used in the management of COVID-19. We then summarize other challenging issues that may happen in PWE, who have COVID-19 and are receiving treatment.

BackgroundDietary fish is a rich source of Omega-3 poly-unsaturated fatty acids (PUFAs). These compounds may have protective effect against cardiovascular events possibly by modifying lipid profiles. Consequently, fish oil supplements are produced commercially to complement low fish intake. It is not clear if both interventions have similar effects. The aim of this trial was to compare the anti-hyperlipidemic effect of omega3 fatty acid supplements with fresh fish.MethodA total of 106 patients with hyperlipidemia were randomized. One group received 2 g/day of omega-3 capsules for a period of 8 weeks and the other group received a mean of 250 g trout fish twice weekly (for dinner and lunch) for the same time period. The effects of these diets on the lipid profile after the intervention were compared between the two groups.ResultsData from 48 patients in fish oil group and 47 patients from fish group was used for final analysis. In both groups, total cholesterol, non-HDL cholesterol, triglyceride (TG) levels, and Castelli I index (total cholesterol/HDL ratio) were reduced significantly following the treatment; however, dietary-fish intake had a more pronounced effect (−85.08 ± 74.82 vs. −30.75 ± 89.00, P < 0.001; 75.06 ± 35.43 vs. −16.93 ± 40.21, P < 0.001; −66.55 ± 30.79 vs. −12.7 ± 35.48, P = 0.003; and −0.77 ± 1.39 vs. −3.02 ± 1.85, P < 0.001; respectively). HDL level was increased in both groups with a higher effect in dietary fish group (4.47 ± 7.83 vs. 8.51 ± 8.79, P = 0.022). Atherogenic (Log [TG/HDL ratio]) and Castelli II (LDL/HDL ratio) indices did not change in fish oil group while were reduced significantly by fresh fish consumption (−0.04 ± 0.27 vs. −0.26 ± 0.17, P < 0.001; and 0.15 ± 0.7 vs. -1.32 ± 1.15, P < 0.001, respectively). LDL level was increased in the supplementation group, while it was significantly reduced in the dietary-fish group (+18.7 ± 24.97 vs. −22.75 ± 27.28, P < 0.001).ConclusionConsumption of fresh fish seems to be superior in positively modifying the lipid profiles which may have important translations in the occurrence of cardiovascular events.

Background:The role of herbal medicine is now well documented in preventing and controlling diabetes mellitus. The main aim of this study was to evaluate the effects of walnut oil consumption on lipid profiles of hyperlipidemic patients with type 2 diabetes.Methods:In a randomized, double-blind, placebo-controlled clinical trial, 100 hyperlipidemic type 2 diabetic patients aged 35–75 years were assigned to receive 15 cc Persian walnut oil or placebo every day for 90 days. The primary outcomes were the lipid profiles.Results:Consumption of walnut oil by type 2 hyperlipidemic diabetic patients resulted in a significant decrease in total cholesterol levels (treatment difference (TD)=−30.04, P<0.001), triglyceride (TG) level (TD=−15.04, P=0.021), low-density lipoprotein (LDL) level (TD=−30.44, P<0.001) and total cholesterol to high-density lipoprotein (HDL) ratio (TD=−0.72, P<0.001) compared to the control group. There was a trend toward increasing HDL level with consumption of walnut oil (TD=2.28, P=0.06). Frequency of patients reaching a LDL level below 100 was higher in the case group (20 vs 0%).Conclusions:Addition of walnut oil in the daily diet of type 2 diabetic patients improves lipid profiles. Thus, it may be associated with a coronary artery disease risk factor modulation. Also, walnut oil may serve as a helpful natural remedy for hyperlipidemic patients with type 2 diabetes.

Introduction: Cardiac dysfunction is a major cause of morbidity and mortality in patients with end-stage renal disease (ESRD). Previous studies have shown that kidney transplantation can reverse some of the gross changes in the myocardial structure such as left ventricular ejection fraction (LVEF) and volumes. Whether kidney transplantation can reverse the subtle and early myocardial changes in ESRD patients who do not suffer from gross alternations in myocardial function is not yet studied. The aim of this study was to answer this question. Methods: We followed 25 patients with ESRD at baseline that all of them had a kidney transplant and were reassessed 1 month after the transplantation. Conventional and speckle tracking echocardiography (STE)was done at baseline and 1 month after kidney transplantation in patients. Results: LV hypertrophy was the most prevalent finding at baseline (58%), followed by diastolic dysfunction (53%). Kidney transplantation significantly improved the ejection fraction (EF) (treatment effect = 4.23 ± 2.06%; P = 0.046) and apical 4-chamber strain (treatment effect = -0.89 ± 0.37%; P = 0.021) in the patients. It also reduced the LV mass index (treatment effect = -73.82 ± 11.6; P < 0.001) and relative wall thickness (treatment effect = -0.056±0.023; P = 0.021). Other variables including global longitudinal strain and diastolic dysfunction were not improved significantly. Conclusion: STE may show early improvements in myocardial function 1 month after renal transplantation.

Background and objectiveCardiac involvement due to iron overload is the most common cause of morbidity and mortality in patients with thalassemia, and many patients remain asymptomatic until the late stages. Therefore, early detection of heart problems in such patients at subclinical stages can improve the prognosis of these patients. We investigated the role of speckled tracking (SI) and tissue Doppler echocardiography (TDI) in early detection of iron overload in these patients.Methods52 thalassemic patients who were receiving regular blood transfusion with normal global LV function were examined by two- and three-dimensional echocardiography. Cardiac MRI was done and T2* images were considered as the non-invasive gold standard for evaluating cardiac iron deposition. Serum ferritin level was assessed and the relationships between serum ferritin levels and echo finding with cardiac MRI T2* was investigated.ResultsNo significant relationship was seen between serum ferritin levels and cardiac MRI T2*. Among the echocardiographic findings, septal systolic myocardial velocity (P = 0.002 and r = 0.43) and global strain (GLS) (P = 0.000 and r = 0.60) were significantly associated with T2*. A GLS < 19.5 could predict a T2* level below 20 by 82.14% sensitivity and 86.36% specificity (area under the curve = 0.87; p < 0.0001).ConclusionWhile serum ferritin level and ejection fraction are not useful candidates, GLS may be used as a valuable marker to screen thalassemia patients for myocardial iron deposition, using a cut off value below − 19.5. This approach may facilitate the cardiac follow up, reduce the costs, and contribute to preventing deterioration of cardiac function in countries with limited availability of cardiac MRI.

Background Trials investigating the role of mesenchymal stem cells (MSCs) in increasing ejection fraction (LVEF) after acute myocardial infarction (AMI) have raised some controversies. This study was conducted to find whether transplantation of MSCs after AMI can help improve myocardial performance indices or clinical outcomes. Methods Randomized trials which evaluated transplantation of MSCs after AMI were enrolled. The primary outcome was LVEF change. We also assessed the role of cell origin, cell number, transplantation time interval after AMI, and route of cell delivery on the primary outcome. Results Thirteen trials including 956 patients (468 and 488 in the intervention and control arms) were enrolled. After excluding the biased data, LVEF was significantly increased compared to the baseline among those who received MSC (WMD = 3.78%, 95% CI: 2.14 to 5.42, p < 0.001, I2 = 90.2%) with more pronounced effect if the transplantation occurred within the first week after AMI (MD = 5.74%, 95%CI: 4.297 to 7.183; I2 = 79.2% p < 0.001). The efficacy of trans-endocardial injection was similar to that of intracoronary infusion (4% [95%CI: 2.741 to 5.259, p < 0.001] vs. 3.565% [95%CI: 1.912 to 5.218, p < 0.001], respectively). MSC doses of lower and higher than 107 cells did not improve LVEF differently (5.24% [95%CI: 2.06 to 8.82, p = 0.001] vs. 3.19% [95%CI: 0.17 to 6.12, p = 0.04], respectively). Conclusion Transplantation of MSCs after AMI significantly increases LVEF, showing a higher efficacy if done in the first week. Further clinical studies should be conducted to investigate long-term clinical outcomes such as heart failure and cardiovascular mortality.

BackgroundMesenchymal stromal cells (MSCs) as multipotent cells with the capacity to be differentiated into several cell lineages are promising sources for cell therapy and tissue engineering nowadays. Today most of culturing media are supplemented with fetal bovine serum (FBS). But FBS containing culturing media may raise the possibility of zoonotic infections and immunological reactions in cell therapy conditions. Numerous investigations have been performed to assess the use of FBS-free culturing systems for bone marrow derived mesenchymal stromal cell isolation.ObjectivesThe present investigation aimed to assess the effect of serum-free media on growth and differentiating capacity of adipose tissue- derived MSCs.Materials and MethodsApproximately, 1cm3 surgically waste sterile adipose tissue was digested with collagenase-I leading to a single cell suspension. The isolated cells were cultured in Ultra Culture media supplemented with 2% Ultroser G. MSC’s isolation was confirmed with respect to morphology, flowcytometry, adipogenic and osteogenic differentiation potentials.ResultsThe isolated cells showed adherent spindle shaped morphology, expanded rapidly and revealed expected MSC flowcytometric characteristics; they were positive for CD73, CD90, CD105, CD44, CD166, CD44 and negative for hematopoietic antigen such as CD45, CD34 and CD14. They could also be differentiated successfully into osteoblast and adipocyte, being confirmed by using Alizarin Red and Oil red O staining, respectively.ConclusionsAccording to the results of the present study, it can be concluded that adipose derived MSCs can be cultured in serum-free media with no change in their differentiating capacity. This finding gives us a hope for future cell therapy studies and trials with little concern about zoonotic infections or immunological reaction.

Background It is not clear whether risk stratification can help choose the most favourable systolic blood pressure target for primary prevention of cardiovascular events. Design A secondary analysis of Systolic Blood Pressure Intervention Trial (SPRINT). Methods To perform a secondary analysis, we obtained the data from SPRINT from the National Heart, Lung, and Blood Institute data repository centre. In SPRINT, an open-label trial, participants without diabetes with systolic blood pressure of ≥130 mmHg were randomly assigned to intensive and standard treatment groups with systolic blood pressure targets of <120 and <140 mmHg, respectively. The primary composite outcome was myocardial infarction and other acute coronary syndromes, stroke, heart failure, or death from cardiovascular causes. Here, we have analysed data from participants without cardiovascular disease and chronic kidney disease aged under 75 years categorised based on the baseline 10-year Framingham risk score (<10% (low risk); ≥10% and <15% (intermediate risk); ≥15% (high risk)). Results A total of 4298 patients were included in the analysis. With intensive treatment, there was a significant reduction in the primary outcome events in patients at high risk (0.86% per year vs. 1.81% per year; hazard ratio (HR) 0.51; 95% confidence interval (CI) 0.31 to 0.85; P = 0.010), and at intermediate risk (0.60% per year vs. 1.46% per year; HR 0.37; 95% CI 0.17 to 0.82; P = 0.014) but not for those at low risk (0.75% per year vs. 0.57% per year; HR 1.14; 95% CI 0.55 to 2.38; P = 0.714). Conclusions Intensive systolic blood pressure reduction is beneficial for primary prevention of cardiovascular morbidity and mortality in patients without diabetes with more than low cardiac risk (above 10%).
