Abstract
Multiple sclerosis (MS) is a condition characterized by inflammation in the central nervous system (CNS), impacting sensory, motor, and cognitive abilities. Globally, around three million individuals are affected by MS, with up to 97,000 cases in Iran attributed to genetic predispositions along with various environmental factors like smoking. Cognitive impairment affects a significant portion of patients, ranging from 45% to 70%. This study investigates the impact of regular aerobic swimming exercise for four weeks, mild cognitive impairment induced by encephalomyelitis, and their combination on the expression of microRNA-142-3p and its correlation with the release of brain-derived neurotrophic factor (BDNF) in relation to spatial memory. Twenty-one C57BL/6 mice were divided into three groups. RT-PCR was used for microRNA expression analysis, and BDNF levels were assessed via western blotting. Clinical scores and animal weights were monitored daily. EAE induction led to an increase in microRNA-142-3p expression and a decrease in BDNF levels compared to the control group. Exercise inversed them significantly, and improved spatial memory. Our findings indicate that engaging in regular swimming exercise can counteract the up-regulation of miR-142-3p in brain tissue, which likely contributes to mild cognitive impairment induced by MS. Additionally, the increase in BDNF following exercise appears to be associated with miR-142-3p and the enhancement of cognitive function. Thus, the therapeutic benefits of exercise, particularly in releasing BDNF to improve cognitive function in MS patients, warrant consideration. Lifestyle modifications have the potential to effectively modulate environmental influences and ethnicity, underscoring their significance in MS management.

Abstract
Driven by the limitations and obstacles of the available approaches and medications for multiple sclerosis (MS) that still cannot treat the disease, but only aid in accelerating the recovery from its attacks, the use of naturally occurring molecules as a potentially safe and effective treatment for MS is being explored in model organisms. MS is a devastating disease involving the brain and spinal cord, and its symptoms vary widely. Multiple molecular pathways are involved in the pathogenesis of the disease. The present review showcases the recent advancements in harnessing nature's resources to combat MS. By deciphering the molecular pathways involved in the pathogenesis of the disease, a wealth of potential therapeutic agents is uncovered that may revolutionize the treatment of MS. Thus, a new hope can be envisioned in the future, aiming at paving the way toward identifying novel safe alternatives to improve the lives of patients with MS.

Fazia T, Baldrighi GN, Nova A, Bernardinelli L. A systematic review of Mendelian randomization studies on multiple sclerosis. Eur J Neurosci 2023; 58:3172-3194.

Abstract
Mendelian randomization (MR) is a powerful approach for assessing the causal effect of putative risk factors on an outcome, using genetic variants as instrumental variables. The methodology and application developed in the framework of MR have been dramatically improved, taking advantage of the many public genome-wide association study (GWAS) data. The availability of summary-level data allowed to perform numerous MR studies especially for complex diseases, pinpointing modifiable exposures causally related to increased or decreased disease risk. Multiple sclerosis (MS) is a complex multifactorial disease whose aetiology involves both genetic and non-genetic risk factors and their interplay. Previous observational studies have revealed associations between candidate modifiable exposures and MS risk; although being prone to confounding, and reverse causation, these studies were unable to draw causal conclusions. MR analysis addresses the limitations of observational studies and allows to establish reliable and accurate causal conclusions. Here, we systematically reviewed the studies evaluating the causal effect, through MR, of genetic and non-genetic exposures on MS risk. Among 107 papers found, only 42 were eligible for final evaluation and qualitative synthesis. We found that, above all, low vitamin D levels and high adult body mass index (BMI) appear to be uncontested risk factors for increased MS risk.

Cureus 2022; 14:e24181.

Abstract
Introduction Multiple sclerosis (MS) is an autoimmune disease that can be disabling to patients. Smoking has been proposed to be a risk factor for MS and to increase the risk of progression of the disease and its severity. However, it is still not clear how smoking affects people with MS (PwMS) regarding disease phenotype, symptoms, relapses, course, and disability. The aim of this study is to investigate the effect of smoking on PwMS in Saudi Arabia. Methods This is an online questionnaire-based cross-sectional study. PwMS were randomly contacted through different MS societies and associations to participate in the study. The questionnaire inquired about demographics, MS phenotype and severity, and smoking status of the participants. Data were collected between May 30, 2021, and July 5, 2021. Results Four hundred twenty-nine PwMS participated in the study. The mean age was 33.7, with a mean disease duration of 8.1 years. About 61.1% of the participants were female. About 62.2% did not know the specific MS phenotype they have. About 35.7% were current or previous smokers, with a mean smoking duration of 13.9 years. Smoking was significantly associated with the presence of multiple MS symptoms (p-value = 0.009) and their number (p-value = 0.050). In addition, there was a significant positive correlation between pack-years smoking and the number of MS symptoms with a Pearson's r value of 0.165 (p-value = 0.001). No significant associations were found between smoking and recent relapses and disease progression, disability in terms of walking, needing a cane, or needing a wheelchair. Conclusion Smoking was shown to have a significant effect on the number of symptoms experienced by PwMS. Higher pack-years of smoking correlates positively and significantly with a higher number of MS symptoms. Further studies to examine these relations are hence warranted.
