Inflammatory markers and functional outcome score in different subgroups of ischaemic stroke: a prospective cohort study.

Background: Acute ischaemic stroke (AIS) is a leading cause of disability and mortality worldwide. Determining subgroups and outcomes of AIS may lead to better treatment. We aimed to investigate the relationship between inflammatory markers and subgroups of AIS with further follow-up of patients in terms of functional outcome score. Methods: In this prospective cohort study, we examined white cell count (WCC), neutrophil count, lymphocyte count, neutrophil-to-lymphocyte ratio (NLR), erythrocyte sedimentation rate (ESR) and qualitative C reactive protein (CRP), in the first 24 hours of patients' admission. Patients were assigned to AIS subgroups as defined by the TOAST criteria. Then patients' disability score was followed up after 3 and 6 months, using the modified Rankin Scale. Results: We included 217 patients with AIS. The mean age of participants was 72.07 years, and we included 92 women (42.4%). For the AIS subgroup, 83 (38.25%) patients had large artery atherosclerosis (LAA), 41 (18.89%) had cardioembolism and 62 (28.57) had small vessel obstruction. Neutrophil count and NLR showed a statistically significant difference in the subgroups of AIS and were highest in the 'other' subgroup of AIS (p<0.05). Lymphocyte count, ESR and qualitative CRP showed no statistically significant difference between subgroups (p>0.05). WCC, neutrophil count and NLR showed a positive correlation with functional outcomes (p<0.05), other markers did not correlate with outcomes (pp>0.05). Conclusion: We can conclude that neutrophil count and NLR are available inflammatory biomarkers for predicting outcomes and these two biomarkers are associated with AIS subgroups. However, ESR, qualitative CRP and lymphocyte count do not appear to be correlated with outcomes or subgroup of AIS.

Association between major dietary patterns and Parkinson's disease risk: a case-control study.

BACKGROUND: There has been emerging attention to investigate the possible role of some dietary factors in the pathogenesis of Parkinson's disease (PD); however, evidence about the relationship between dietary components and the risk of PD is limited. The aim of this study was to determine the association between major dietary patterns and the risk of PD. METHODS: This case-control study was performed on 105 patients with newly diagnosed PD and 215 healthy controls. Diagnosis of Parkinson's disease was made based on the UK Brain Bank criteria. Usual dietary intakes were collected by a validated semi-quantitative food frequency questionnaire. Dietary patterns were detected by principal component analysis. RESULTS: Four dietary patterns, including traditional, healthy, western, and light dietary patterns, were identified. After considering all potential confounders, individuals with the highest tertile of traditional dietary pattern scores had a lower risk of PD than those with the lowest tertile (OR: 0.002; 95% CI: 0.000-0.016). A similar inverse association between the healthy pattern (OR: 0.314; 95% CI: 0.131-0.750) and light pattern (OR: 0.282; 95% CI: 0.121-0.654) and risk of PD was revealed. In contrast, adherence to the western dietary pattern was associated with PD incidence (OR: 7.26; 95% CI: 2.76-19.09). CONCLUSIONS: The findings of this study suggest that adherence to western dietary pattern could increase the risk of PD by approximately seven times. However, the traditional, healthy, and light dietary patterns had an inverse relationship with PD risk.

The effect of distance nurse-led fatigue management on fatigue, sleep quality, and self-efficacy in patients with multiple sclerosis: a quasi-experimental study.

BACKGROUND: Fatigue is one of the most common problems in patients with multiple sclerosis (MS) and has adverse effects on their sleep status and self-efficacy. This study aimed to determine the effect of distance nurse-led fatigue management on fatigue, sleep quality, and self-efficacy in patients with MS. METHODS: This quasi-experimental study was performed on 60 patients with MS in Arak, Iran. Subjects were randomly assigned into intervention and control groups. The intervention group received eight sessions of nurse-led fatigue management training through the Skyroom platform. The control group received only the usual programs. Data were collected before and two months after the intervention using the Fatigue Severity Scale, the Pittsburgh Sleep Quality Index, and the Multiple Sclerosis Self-Efficacy Scale. The significance level in this study was determined 0.05. RESULTS: After the intervention, the mean score of fatigue severity in the intervention group was significantly lower than the control group (2.52 ± 0.40 vs 5.65 ± 0.52) (P < 0.001). Also, after the intervention, the mean score of self-efficacy in the intervention group was significantly higher than the control group (49.37 ± 3.25 vs 24.43 ± 2.52) (P < 0.001). Furthermore, after the intervention the mean score of sleep quality was lower in intervention group (11.92 ± 2.01) than the control group (15.46 ± 1.40) (P < 0.001). CONCLUSION: Distance nurse-led fatigue management improved fatigue, sleep quality, and self-efficacy in patients with MS. We recommend the use of these courses as an important step toward improving fatigue, sleep quality, and self-efficacy among these patients.

Do prior neurological comorbidities predict COVID-19 severity and death? A 25-month cross-sectional multicenter study on 7370 patients.

BACKGROUND: The prognosis of COVID-19 cases that suffer from particular comorbidities is worse. The impact of chronic neurological disorders (CNDs) on the outcome of COVID-19 patients is not clear yet. This study aimed to assess whether CNDs can predict in-hospital mortality or severity in COVID-19 patients. METHODS: Following a cross-sectional design, all consecutive hospitalized patients with PCR-confirmed COVID-19 who were hospitalized at three centers from February 20th, 2020 to March 20th, 2022, were studied. CND was defined as neurological conditions resulting in permanent disability. Data on demographic and clinical characteristics, COVID-19 severity, treatment, and laboratory findings were evaluated. A multivariate Cox-regression log-rank test was used to assess the primary outcome, which was in-hospital all-cause mortality. The relationship among CND, COVID-19 severity and abnormal laboratory findings was analyzed as a secondary endpoint. RESULTS: We studied 7370 cases, 43.6% female, with a mean age of 58.7 years. 1654 (22.4%) patients had one or more CNDs. Patients with CNDs had higher age, were more disabled at baseline, and had more vascular risk factors and comorbidities. The ICU admission rate in CND patients with 59.7% was more frequent than the figure among non-CND patients with 20.3% (p = 0.044). Mortality of those with CND was 43.4%, in comparison with 12.8% in other participants (p = 0.005). Based on the Cox regression analysis, CND could independently predict death (HR 1.198, 95% CI 1.023-3.298, p = 0.003). CONCLUSION: CNDs could independently predict the death and severity of COVID-19. Therefore, early diagnosis of COVID-19 should be considered in CND patients.

Does the Serum Expression Level of High-Mobility Group Box 1 (HMGB1) in Multiple Sclerosis Patients have a Relationship with Physical and Psychological Status? A 12-Month Follow-Up Study on Newly Diagnosed MS Patients.

Background: There is a strong need to identify simple and cost-effective biomarkers for multiple sclerosis (MS). Objectives: To evaluate the serum levels of receptor for advanced glycation end products (RAGE) ligand, the high-mobility group box (HMGB) 1 and its correlation with changes in the physical and psychological indicators in MS patients. Methods: During the 12-month follow-up, the serum level of HMGB1, expanded disability status scale (EDSS) score, rate of clinical relapse, quality of life, and other psychological indicators were assessed at baseline, after 6 months, and after 12 months and compared between 60 newly diagnosed MS patients with 60 healthy controls (HCs). Data were analyzed using t-test and Mann-Whitney U test, two-way repeated measures analysis of variance (ANOVA) and Spearman's rank correlation coefficient. Results: A significant decrease was observed in the EDSS score (P < 0.001) and a significant increase in the serum level of HMGB1 in all MS patients (P = 0.009). The serum level of HMGB1 was higher in MS patients, compared with HCs (baseline: 65.8%, P = 0.007; six-month follow-up: 73.9%, P = 0.004; and 12-month follow-up: 77.6%, P = 0.021). There were significant positive correlations between the serum level of HMGB1 and scores of MS impact scale-psychological subscale (MSIS-PS) (r = 0.59, P < 0.001), Beck depression inventory (BDI) (r = 0.491, P = 0.031), and Pittsburgh sleep quality index (PSQI) (r = 0.471, P = 0.035). Conclusion: The serum level of HMGB1 could predict the patients' psychiatric status better than their physical status.

Gene expression of semaphorin-3A, semaphorin-7A, neuropilin-1, plexin-C1, and ß1 integrin in treated-multiple sclerosis patients.

OBJECTIVE: Recently, members of the semaphorin family have received major attention in various medical fields, especially autoimmunity. In this study, we selected semaphorin-3A (Sema3A), semaphorin-7A (Sema7A), and their receptors to determine the possible relationship between these molecules and multiple sclerosis (MS). METHOD: We measured the gene expression of Sema3A, Sema7A, neuropilin-1 (NP-1), plexin-C1, and ß1 integrin in the blood samples of relapsing-remitting multiple sclerosis (RRMS) patients, treated with high-dose interferon-ß1a (IFN-ß1a), low-dose IFN-ß1a, IFN-ß1b, and glatiramer acetate (GA) via quantitative real-time polymerase chain reaction (qRT-PCR) assay, and then, compared the results of treatment-naive patients with the healthy controls. RESULTS: The gene expression of Sema3A (P = 0.02), NP-1 (P < 0.001), and plexin-C1 (P < 0.01) significantly decreased in the treatment-naive group, compared to the healthy controls. Sema3A significantly increased in all treated patients, compared to the treatment-naive patients (P < 0.001). However, expression of NP-1 (P < 0.001), plexin-C1 (P < 0.001), and ß1 integrin (P < 0.05) only increased in patients receiving high-dose IFN-ß1a, IFN-ß1b, and GA. Expression of Sema7A increased in only two groups of patients treated with IFN-ß1b (P < 0.001) and GA (P = 0.018), without any significant decrease in the treatment-naive group, compared to the healthy controls (P > 0.05). CONCLUSION: Our findings confirm that the presence of Sema3A, Sema7A, and their receptors can play critical roles in the treatment of MS patients. Therefore, they can be potential target molecules for MS treatment in the future.

The effect of foot reflexology on constipation and quality of life in patients with multiple sclerosis. A randomized controlled trial.

BACKGROUND: Constipation is a major problem in most patients with multiple sclerosis (MS). The aim of this study was to investigate the effect of foot reflexology on constipation and quality of life in patients with MS. METHODS: This study was a randomized controlled trial, in which 63 patients with MS referred to Arak MS Society, Iran were participated (from May to Dec. 2018). In this study participants were selected according to inclusion criteria and randomly divided into intervention (n = 33) and control (n = 30) groups. In the intervention group, foot reflexology was applied twice a week for 6 weeks (each session lasted about 30-40 min). Data were collected using demographic questionnaire, Constipation Assessment Scale (CAS) and Short Form (SF) 36 Quality of Life (QOL) questionnaire. Finally, the data were analyzed using SPSS Ver. 16 and descriptive and inferential statistical tests. RESULTS: The results of the study showed that severity of constipation and QOL score were not significant between the two groups before intervention (p > 0.05), but; after intervention, severity of constipation significantly decreased in the reflexology group (p < 0.05). Nevertheless, after intervention, the QOL was improved in the reflexology group compared to the control group but was not significant (p > 0.05). CONCLUSION: The results of this study showed that foot reflexology, as an effective intervention can be useful in management of constipation in patients with MS. Therefore, this intervention can be applied as a safe method for the decrease of constipation in MS patients.

Comparing the efficacy of ondansetron and granisetron augmentation in treatment-resistant obsessive-compulsive disorder: a randomized double-blind placebo-controlled study.

This study aimed to assess the efficacy and tolerability of ondansetron vs. granisetron in patients with treatment-resistant obsessive-compulsive disorder. A randomized clinical trial conducted on 135 patients with a Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) diagnosis of obsessive-compulsive disorder, who were treatment-resistant and receiving stable treatment with selective serotonin reuptake inhibitors and antipsychotic, received 14 weeks (phase I, intervention period) of placebo (n = 45), ondansetron (n = 45, 4 mg), and granisetron (n = 45, 2 mg) daily augmentations. Patients were rated every 2 weeks using the Yale-Brown Obsessive Compulsive Scale. Upon completion of intervention course, patients were followed for 4 weeks (phase II, discontinuation period). The collected data were analyzed in SPSS Version 22, with χ test; Fisher's exact test and independent t-test, according to the intention-to-treat principle. Two-factor repeated measure analysis of variance was used to compare score changes over phases. P < 0.05 was considered to be statistically significant. At week 14, reduction in Yale-Brown Obsessive Compulsive Scale scores in ondansetron, granisetron and placebo groups was 41.5%, 39.7% and 15.2%, respectively (P = 0.001). Complete response in the ondansetron group was significantly higher than in the granisetron group ((P = 0.041), risk ratio (95% confidence interval) = 2.33 (1.18-3.045)]. Relapse occurred by three (7.31%) patients in the granisetron group, whereas it was not seen in the ondansetron group [P < 0.001, risk ratio (95% confidence interval) = 2.81 (1.016-4.51)]. The results of this present study confirm the benefit of using ondansetron and granisetron as augmenting agents in treatment-resistant obsessive-compulsive disorder. Our results supported the potential superiority of ondansetron compared to granisetron. This needs to be confirmed in further placebo-controlled augmentation studies.

Assessment of CCL27 and IL-11 in Multiple Sclerosis Patients Treated with Interferon-ß and Glatiramer Acetate.

INTRODUCTION: Multiple sclerosis (MS) is a neuroinflammatory autoimmune disease which involves the central nervous -system. Although the primary cause of MS is obscure, effects of some cytokine and chemokine patterns in both innate and adaptive immune systems have been described. -Objectives: Since limited studies have examined the role of interleukin (IL)-11 and chemokine CCL27 in MS, we aimed to identify changes in IL-11 and CCL27 gene expression and serum levels in relapsing-remitting MS (RRMS) patients, treated with interferon (IFN)-ß and glatiramer acetate (GA). METHODS: The serum level and gene expression of IL-11 and CCL27 were measured and compared between treatment-naïve MS patients and RRMS patients who were treated with high-dose IFN-ß1a, low-dose IFN-ß1a, IFN-ß1b, and GA via enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction. RESULTS: A significant decrease was observed in the serum level of CCL27 in treatment-naïve patients and IFN-ß1b-treated patients compared to the healthy controls. On the other hand, a significant increase was found in the protein level of CCL27 in low-dose and high-dose IFN-ß1a groups compared to the treatment-naïve group. In addition, CCL27 gene expression was higher in patients treated with GA than in the treatment-naïve group. There were no significant changes in the gene expression or protein level of IL-11 in all experimental groups. Additionally, a positive correlation was found between IL-11 and CCL-27. CONCLUSION: Our results suggest the inflammatory role of CCL27 in MS patients, while IFN-ß1a seems to play a compensatory role for this chemokine.

Use of melatonin versus valproic acid in prophylaxis of migraine patients: A double-blind randomized clinical trial.

BACKGROUND: Melatonin is known to be effective in curing migraine. OBJECTIVE: This study aimed to investigate the therapeutic effect of melatonin versus sodium valproate in the prophylaxis of chronic migraine. METHODS: This randomized, double-blind, placebo-controlled clinical trial included patients with chronic migraine who were divided into three equal sized groups, and baseline therapy with nortriptyline (10-25 mg) and propranolol (20-40 mg) was used. Patients in groups A, B, and C were adjunctively treated daily with 3 mg melatonin, 200 mg sodium valproate, and a placebo, respectively. The patients underwent treatment for 2 months and follow-up was done at baseline (baseline), first (I) and second month (II). Attack frequency (AF), attack duration, attack severity, Migraine Disability Assessment (MIDAS) score (within 3 months in two steps), analgesic intake, and drug side effects between the groups and during follow-up were compared. RESULTS: The mean of monthly AF (melatonin: baseline: 4.2, I: 3.1, II: 2.5, p = 0.018; valproate: baseline: 4.3, I: 3.1, II: 2.3, p = 0.001; placebo: baseline: 4.1, I: 3.8, II: 3.8 p = 0.211), attack duration (hr) (melatonin: baseline: 19.8, I: 10.1, II: 8.7, p < 0.001; valproate: baseline: 19.5, I: 10.2, II: 8.8, p < 0.001; placebo: baseline: 19.6, I: 15.4, II: 14.1, p = 0.271), attack severity (melatonin: baseline: 7.3, I: 5.4, II: 3.5, p < 0.001; valproate: baseline: 7.4, I: 5.3, II: 3.4, p = 0.000; placebo: baseline: 7.3, I: 6.4, II: 6, p = 0.321), and MIDAS score (melatonin: baseline: 15.2, II: 8.9, p = 0.005; valproate: baseline: 16.1, II: 8.3, p = 0.001; placebo: baseline: 16, II: 12.1, p = 0.44), were significantly reduced in the melatonin and sodium valproate groups, but not in the placebo groups. Adverse events were reported in 11 patients (10.47%): 2 (5.71%) during melatonin treatment, 8 (22.85%) during valproate, and 1 (2.85%) during placebo. CONCLUSION: The adjuvant treatment with melatonin was found to be superior to the placebo and had the same clinical efficacy as sodium valproate, but with higher tolerability. Melatonin may prove to be an efficient substitute for sodium valproate, as a chronic migraine prophylaxis.

Attention Deficit Hyperactivity Disorder and Anxiety in Children With Malignancy.

Attention deficit hyperactivity disorder (ADHD) and Anxiety is the most common childhood psychiatric disorder. Based on studies, these disorders are more prevalent in some chronic disease. This study aimed at investigating the prevalence of ADHD and anxiety in children with malignancy and anxiety in their parents and comparing the results with those of the control group. One hundred, 3-15-year-old children with malignancy and 100 healthy children without malignancy or any chronic disease were included in this case-control study as case and control groups, respectively. Subjects were selected from children who were referred to the pediatric ward of Amir Kabir Hospital of Arak, Iran, in the form of simple probability and based on inclusion and exclusion criteria. ADHD and Anxiety were diagnosed by Conner's Parent Rating Scale-48 (CPRS-48) and Hamilton Anxiety Rating Scale (HARS) and were confirmed by psychologist consult. Data were analyzed by Student t-test in SPSS18. ADHD was observed in 23 cases (23%) with malignancy and 5 controls (5%) (P=0.001). In the case group, 57 children (57%) and 45 of their parents (45%) were suffering from anxiety while in the control group the figure was observed in 12 children (12%) and 11 of their parents (11%) (P=0.001). ADHD and anxiety are more common in children with malignancy as compared with children without malignancy and anxiety is also more common in their parents. Therefore, implementing interventions and psychiatric counseling are recommended for these children and their parents.
