Consanguineous marriage among familial multiple sclerosis subjects: A national registry-based study.

Background: The rising prevalence of familial multiple sclerosis (MS) in Iran has spurred interest in the potential impact of parental consanguinity on the risk of developing the disease. This study aims to aggregate current knowledge on parental consanguinity and its possible effect on MS risk, particularly among familial MS patients from various regions and ethnicities in Iran. The objective is to enhance the understanding of MS genetics and encourage further research in this field. Materials and methods: A cross-sectional study was conducted on clinically definite familial MS (FMS) patients registered in the nationwide MS registry of Iran (NMSRI). Data were extracted and supplemented with structured telephone follow-ups to gather detailed histories of MS in relatives and the familial relationships of the patients' parents. A family penetration score was proposed. Descriptive statistics and inferential statistical tests were used to analyze the data at a significance level of 0.05, adhering to ethical guidelines. Results: Out of 19,911 individuals registered in the NMSRI, 2307 FMS patients across 13 provinces were included in the final analysis. Among these, 385 (19.3 %) reported parental consanguinity, with 283 (14.2 %) having parents who were cousins and 102 (5.1 %) having parents who were distant relatives. The data showed no significant association between parental kinship and variables such as MS phenotype, number of affected relatives with MS, hospitalization rates, and expanded disability status scale score. Similarly, MS severity did not differ based on parental consanguinity (P-value >0.05). While the rate of consanguineous marriage was higher among patients with an onset age less than 18 years, there was no statistically significant difference in disease onset age based on parental consanguinity status. Conclusion: Our study highlights the complexity of factors influencing MS development, including genetic and environmental components. These results highlight the need for further research to achieve a more comprehensive understanding of MS etiology.

Neuromyelitis optica spectrum disorders registry system in Iran: Validity of data sets.

BACKGROUND: A targeted structure for recording, monitoring, and follow-up of patients with neuromyelitis optica spectrum disorders (NMOSD) is in demand. To obtain the correct and uniform standardized information registry system, it is necessary to use a data set that has good validity to help policy-makers systematically plan for improvements in the quality of care. The main goal of the present study was to develop a NMOSD data set for the national registry system in Iran (NMORI) and to evaluate the validity of the presented data set. METHODS: The NMORI data set consisted of baseline characteristics, disease and exposure history, background and past medical history, diagnosis and treatment, clinical features, imaging, and para-clinical findings. The content validity was evaluated by 18 experts from Iran, Japan, and Denmark by scoring each of the questionnaire items in term of transparency, simplicity, and relevance. According to the points given, the content validity index (CVI) and content validity ratio (CVR) scores were calculated and compared with the critical limit. RESULTS: The current study was designed as a 125-items data set which was considered valid. In terms of relevance 110 out of 125 items, simplicity 113 out of 125 items, and transparency 123 out of 125 items had Item-CVI>0.79. All Scale-level-CVI values were greater than 0.9, showing noticeable content validity. In this data set, 112 items had CVR > 0.49, which was considered an acceptable level of significance. CONCLUSION: The implementing of NMORI is important in a developing country such as Iran with significant increasing prevalence of this disease. This registry facilitates a uniform and valid diagnosis and is considered valid for clinical investigation and epidemiological research on NMOSD. Scientists and healthcare policymakers can rely on a validated data set in order to have access to accurate data.

Time interval between the onset of symptoms and diagnosis of multiple sclerosis and the influential factors: A national registry-based study.

OBJECTIVE: The time to diagnosis of multiple sclerosis (MS) is of great importance for early treatment, thereby reducing the disability and burden of the disease. The purpose of this study was to determine the time from the onset of clinical symptoms to the diagnosis of MS and to evaluate the factors associated with a late diagnosis in Iranian MS patients. METHODS: The present cross-sectional study was conducted on patients with MS who were registered in the National MS Registry System of Iran (NMSRI). RESULTS: Overall, 23291 MS patients registered in 18 provinces of Iran were included in this study. The mean (standard deviation) interval between the onset of the disease and diagnosis of MS was 13.42 (32.40) months, and the median was one month. The diagnostic interval of 41.6% of patients was less than one month, and 14.8% of them had a one-month time to diagnosis. Patients with an age of onset below 18 years and those diagnosed after the age of 50 years had a longer time to diagnosis (P<0.001). Patients with primary progressive MS (PPMS) had the longest time to diagnose and those with relapsing-remitting MS (RRMS) had the shortest time (P<0.001). The results of negative binominal regression showed that the average rate of delay in diagnosis in women was 12% less than that in men. The average delay in diagnosis in patients with a positive family history of MS was 23% more than that in others. The rate of delay in the diagnosis of patients with PPMS and secondary progressive MS was 2.22 and 1.66 times higher, respectively, compared with RRMS. CONCLUSION: The findings of the present study revealed that more than half of the MS patients were diagnosed within a one-month interval from the symptom onset, which is an acceptable period. More attention should be paid to patients' access to medical facilities and MS specialists.

Effectiveness of acupuncture for fatigue in patients with relapsing-remitting multiple sclerosis: a randomized controlled trial.

BACKGROUND: Fatigue is experienced by more than 65% of individuals with multiple sclerosis (MS). Some studies have supported the effectiveness of acupuncture in improving the symptoms of MS. OBJECTIVE: The present research was intended to investigate the effectiveness of acupuncture plus amantadine compared with amantadine alone on fatigue in patients with relapsing-remitting MS (RRMS) in the remission stage of the disease. METHODS: In this randomized controlled trial, 60 participants with RRMS suffering from fatigue were recruited and randomized equally to acupuncture (n = 30) and control (n = 30) groups. The acupuncture group received treatment 2 to 3 times per week for 10 sessions over 4 weeks. Both the acupuncture and control groups received amantadine 100 mg daily and routine treatment with immuno-modulators. The primary outcome was the fatigue severity scale (FSS) score, which was evaluated at baseline, and after 2 and 4 weeks. The secondary outcome was the Multiple Sclerosis Quality of Life 54 (MSQOL-54) questionnaire score, measured at baseline and the end of the 4-week treatment period. RESULTS: The severity of fatigue was reduced in both groups. However, after 4 weeks of treatment, the reduction of fatigue in the acupuncture group was more significant than in the control group (P < 0.01, mean difference (MD) = -1.14, 95% confidence interval (CI): -1.83 to -0.45). Quality of life, including mental and physical status, was significantly improved in the acupuncture group compared with the control group (P < 0.05, MD = 9.09, 95% CI: 0.46 to 17.73). No adverse events occurred in any of the participants. CONCLUSIONS: Acupuncture combined with amantadine and routine care compared with amantadine and routine care alone appears to be an effective short-term treatment for reducing fatigue and enhancing quality of life, including physical function and mental status, in patients with RRMS.

Acupuncture for multiple sclerosis: A literature review.

BACKGROUND: Acupuncture as a complementary and alternative medicine (CAM) modality appears to be a helpful integrative therapy for multiple sclerosis (MS). Due to the chronicity of the disease and persistent symptoms, a large number of patients seek to use CAM for the MS treatment. Therefore, the present review aimed to determine the effectiveness of acupuncture in the treatment of multiple sclerosis. METHODS: PUBMED database was searched for English articles (at least English abstracts) in September 2021, including all articles published since the earliest literature until September 2021. Review articles were searched for relevant data. The searched keywords in titles and abstracts included ((acupuncture) OR (electroacupuncture)) AND (multiple sclerosis). RESULTS: Totally, out of 75 studied articles, 31 were included in this research. The advantages of acupuncture are mainly reflected in regulating neuro-immune system, improving the quality of life, reducing fatigue, improving the bladder function, reducing the spasm and pain of the limbs, delaying the progression of the disease, and reducing relapses. CONCLUSIONS: According to the review of the recent articles, traditional Chinese acupuncture and scalp acupuncture appear to help improve the symptoms of multiple sclerosis (including fatigue, neural functional deficits, pain, gait impairments, and bladder dysfunction) and reduce relapses. Therefore, acupuncture could be used as an integrative therapy in patients with MS.

The Correlation of Plasma 25-Hydroxyvitamin D Deficiency With Risk of Breast Neoplasms: A Systematic Review.

CONTEXT: Breast cancer has been considered as one of the most common types of cancer among the women worldwide, and patients with breast neoplasms have been reported with high prevalence of low serum 25-hydroxyvitamin D levels. OBJECTIVES: Our aim was to evaluate the correlation of plasma 25-hydroxyvitamin D deficiency with breast neoplasms risk among women. DATA SOURCES: PubMed database was searched with MeSH (medical subject headings) keywords "vitamin D AND breast neoplasms" which was restricted by original articles written only in English and published from January 1, 2014. STUDY SELECTION: To find the articles that met eligibility criteria, titles and abstracts were examined. DATA EXTRACTION: This systematic review was conducted according to PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement. Critical appraising of evidence was performed, using the study quality assessment tools of national institutes of health, national heart, lung and blood institute (NHLBI). RESULTS: Overall, 76 potential articles were identified and after screening, 13 articles met eligible criteria for inclusion. Definition of low vitamin D levels varied greatly among studies, making comparisons difficult, but most of them have defined deficiency as 25(OH)D < 20 ng/mL. Evidence was mainly of fair quality. CONCLUSIONS: This study has provided evidence that vitamin D deficiency has been very prevalent in patients with breast neoplasms, more than comparable matched control population, and risk of breast cancer has increased with low vitamin D levels, suggesting the need for high quality studies that assessed the health consequences attributable to vitamin D deficiency employing standard definitions.
