Effect of ginseng on fatigue related to neuromyelitis optica spectrum disorder: A double-blinded randomized controlled clinical trial.

Background: The effects of ginseng on fatigue have been proven in patients with multiple sclerosis (MS), which have several similar manifestations to neuromyelitis optica spectrum disorder (NMOSD) patients. This study was designed to evaluate the effects of ginseng on fatigue in NMOSD patients. Methods: In this double-blinded randomized controlled clinical trial, 64 patients were recruited and were allocated into two study groups (ginseng or placebo) via block randomization. The participants received either 250-mg ginseng or placebo twice daily for a 3-month period. Also, the measurement of outcome was performed using the valid and reliable Persian version of fatigue severity scale (FSS) questionnaire, which was filled by patients once after enrollment in the study and once at the end of the study post-intervention. Results: In total, 58 patients finished the study with no major side effects. There were no significant differences in demographic, clinical, as well as FSS between two study groups (p>0.05). Ginseng supplementation significantly reduced fatigue (40.21±13.51 vs. 28.97±14.18; p˂0.01), while patients in the placebo group showed significantly higher fatigue score after 3 months post-intervention (35.03±13.51 vs. 38.79±12.27; P: 0.02). The extent of changes in the fatigue score in the ginseng group was significantly greater than in the placebo group (p ˂0.01). Conclusion: This study revealed positive effects of ginseng on reducing fatigue in NMOSD patients with no major side effects. In this regard, further studies are warranted to evaluate and clarify the effects of ginseng on fatigue in NMOSD.

Pressure ulcers and acute risk factors in individuals with traumatic spinal fractures with or without spinal cord injuries: A prospective analysis of the National Spinal Column/Cord Injury Registry of Iran (NSCIR-IR) data.

PURPOSE: To identify risk factors for developing pressure ulcers (PUs) in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries (SCIs). METHODS: Data were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran (NSCIR-IR) from individuals with traumatic spinal fractures with or without SCIs, inclusive of the hospital stay from admission to discharge. Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay. The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification. In addition to PU, following data were also extracted from the NSCIR-IR datasets during the period of 2015 - 2021: age, sex, Glasgow coma scale score at admission, having SCIs, marital status, surgery for a spinal fracture, American Spinal Injury Association impairment scale (AIS), urinary incontinence, level of education, admitted center, length of stay in the intensive care unit (ICU), hypertension, respiratory diseases, consumption of cigarettes, diabetes mellitus and length of stay in the hospital. Logistic regression models were used to estimate the unadjusted and adjusted odds ratio (OR) with 95% confidence intervals (CI). RESULTS: Altogether 2785 participants with traumatic spinal fractures were included. Among them, 87 (3.1%) developed PU during their hospital stay and 392 (14.1%) had SCIs. In the SCI population, 63 (16.1%) developed PU during hospital stay. Univariate logistic regression for the whole sample showed that marital status, having SCIs, urinary incontinence, level of education, treating center, number of days in the ICU, age, and Glasgow coma scale score were significant predictors for PUs. However, further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center, marital status, having SCIs, and the number of days in the ICU. For the subgroup of individuals with SCIs, marital status, AIS, urinary incontinence, level of education, the treating center, the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis. After adjustment in the multivariate model, the treating center, marital status (singles vs. marrieds, OR = 3.06, 95% CI: 1.55 - 6.03, p = 0.001), and number of days in the ICU (OR = 1.06, 95% CI: 1.04 - 1.09, p < 0.001) maintained significance. CONCLUSIONS: These data confirm that individuals with traumatic spinal fractures and SCIs, especially single young patients who suffer from urinary incontinence, grades A-D by AIS, prolonged ICU stay, and more extended hospitalization are at increased risk for PUs; as a result strategies to minimize PU development need further refinement.

Relationship between fetal middle cerebral artery pulsatility index and cerebroplacental ratio with adverse neonatal outcomes in low-risk pregnancy candidates for elective cesarean section: A cross-sectional study.

Background: The cerebroplacental ratio (CPR) is an important factor for predicting adverse neonatal outcomes in appropriate-for-gestational-age fetuses. Objective: To evaluate whether there is an association between the CPR level and adverse neonatal outcomes in appropriate-for-gestational-age fetuses. Materials and Methods: This cross-sectional study included 150 low-risk pregnant women candidates for elective cesarean sections at the gestational age of 39 wk. CPR and middle cerebral artery pulsatility index (MCA PI) were calculated in participants just before cesarian section. Postnatal complications were defined as an adverse neonatal outcome such as an Apgar score of the neonate ≤ 7 at 5 min, neonatal intensive care unit (NICU) admission, cord arterial pH ≤ 7/14, and meconium stained liquor. Results: The mean age of participants was 31.53 ± 4.91 yr old. The mean CPR was reported as 1.83 ± 0.64. The Chi-square test analysis revealed that a low MCA PI and a low CPR were significantly associated with decreased cord arterial pH, decreased Apgar score at 5 min, and NICU admission (p < 0.001). There was no significant association between umbilical artery PI with arterial cord pH, Apgar score at 5 min, NICU admission, or meconium stained liquor. The Mann-Whitney test showed that a lower fetal weight appropriate for the women's gestational age was significantly associated with a decreased CPR and MCA PI (p < 0.005). There was no significant association between amniotic fluid index and CPR, umbilical artery PI, or MCA PI. Conclusion: The CPR is a significant factor in predicting adverse neonatal outcomes and ultimately neonatal mortality and morbidity of low risk, appropriate-for-gestational-age fetuses.

Effect of Rituximab on the cognitive impairment in patients with secondary progressive multiple sclerosis.

Background: The present study aimed to address the effect of Rituximab on the cognitive impairment in patients with secondary progressive MS (SPMS). Methods: The present interventional study used a convenience sampling method to select the study participants from SPMS patients. All these patients had progressive disability over the last two years before being admitted in the study. Prior to the administration of Rituximab, the minimal assessment of cognitive function in the multiple sclerosis (MACFIMS) test was performed for each patient who was a candidate to be included in this study. This test was repeated by passing 6 and 12 months from the initial treatment with Rituximab. Since the data needed for this study were obtained at different time intervals, so a linear mixed model was used for their analysis. Analysis of variance (ANOVA) was also used to investigate whether time and sex generally affect the cognitive impairments in SPMS patients. A p-value <0.05 was considered as statistically significant in this study. Results: Of the total 35 patients, 34% and 66% were men and women with a mean age of 41.33 and 41.39 years old, respectively. Rituximab showed a significant positive effect on a number of subgroups of MACFIMS test, including Controlled Oral Word Association Test (COWAT) (P-value: 0.038) and Brief Visuospatial Memory Test (BVMT-total) (P: 0.019). Conclusion: The present study revealed that Rituximab has a positive effect on the cognitive impairment resulted from MS in secondary progressive patients.

Levels and Trends of Maternal Mortality and Morbidity by Cause in North Africa and Middle East, 1990 to 2019: An Analysis for the Global Burden of Disease Study 2019.

BACKGROUND: Since 1990, the maternal mortality significantly decreased at global scale as well as the North Africa and Middle East. However, estimates for mortality and morbidity by cause and age at national scale in this region are not available. METHODS: This study is part of the Global Burden of Diseases, Injuries, and Risk Factors study (GBD) 2019. Here we report maternal mortality and morbidity by age and cause across 21 countries in the region from 1990 to 2019. RESULTS: Between 1990 and 2019, maternal mortality ratio (MMR) dropped from 148.8 (129.6-171.2) to 94.3 (73.4-121.1) per 100000 live births in North Africa and Middle East. In 1990, MMR ranged from 6.0 (5.3-6.8) in Kuwait to 502.9 (375.2-655.3) per 100000 live births in Afghanistan. Respective figures for 2019 were 5.1 (4.0-6.4) in Kuwait to 269.9 (195.8-368.6) in Afghanistan. Percentages of deaths under 25 years was 26.0% in 1990 and 23.8% in 2019. Maternal hemorrhage, indirect maternal deaths, and other maternal disorders rank 1st to 3rd in the entire region. Ultimately, there was an evident decrease in MMR along with increase in socio-demographic index from 1990 to 2019 in all countries in the region and an evident convergence across nations. CONCLUSION: MMR has significantly declined in the region since 1990 and only five countries (Afghanistan, Sudan, Yemen, Morocco, and Algeria) out of 21 nations didn't achieve the Sustainable Development Goal (SDG) target of 70 deaths per 100000 live births in 2019. Despite the convergence in trends, there are still disparities across countries.

Neonate, Infant, and Child Mortality by Cause in Provinces of Iran: An Analysis for the Global Burden of Disease Study 2019.

BACKGROUND: Since 1990, neonatal, infant, and child mortality has substantially decreased in Iran. However, estimates for mortality by cause at subnational scale are not available. METHODS: This study is part of the Global Burden of Diseases, Injuries, and Risk Factors study (GBD) 2019. Here we report the number and rates of neonate, infant, and child deaths by cause across provinces of Iran from 1990 to 2019. RESULTS: Between 1990 and 2019, the neonatal mortality rate per 1000 live births decreased from 31.8 (95% UI: 28.1-35.5) to 6.8 (6.1-7.4). The child mortality rates decreased from 71.2 (63.6-79.1) to 11.1 (10.2-12.0) per 1000 live births. Mortality rates among neonates per 1000 live births ranged from 3.1 (2.6-3.7) to 10.0 (9.2-10.8) across provinces in 2019. Child mortality rate per 1000 live births ranged from 5.5 (4.6-6.5) to 17.9 (16.4-19.4) across provinces in 2019. Neonatal disorders, congenital birth defects, and lower respiratory infections were the three main causes of mortality in almost all provinces of Iran. The majority of neonatal disorders were due to neonatal preterm birth and neonatal asphyxia, trauma, and infections. The trends of mortality across provinces from 1990 to 2019 were converging and decreased along with increase in sociodemographic index (SDI). CONCLUSION: All provinces achieved the Sustainable Development Goal 3.2 of neonatal mortality less than 12 and child mortality less than 25 per 1000 live births. However, disparities still exist across provinces, specifically in low-SDI provinces.

Maternal Mortality and Morbidity by Cause in Provinces of Iran, 1990 to 2019: An Analysis for the Global Burden of Disease Study 2019.

BACKGROUND: Since 1990, maternal mortality ratio (MMR) has significantly decreased in Iran. However, estimates for mortality and morbidity by cause at subnational scale are not available. METHODS: This study is part of the Global Burden of Diseases study (GBD) 2019. Here we report maternal mortality and morbidity by age and cause across 31 provinces of Iran from 1990 to 2019. RESULTS: Since 1990, MMR declined from 44.5 (95% UI: 38.6-50.1) to 15.9 (14.7-17.3) per 100000 live births in Iran. In 1990 MMR ranged from 18.5 (11.2-26.4) to 76.9 (38.4-114.7) per 100000 live births across provinces. Respective figures for 2019 were 7.1 (5.2-9.3) to 34.0 (25.1-44.7) per 100000 live births. In 2019, MMR was higher in young women (aged 10 to 14) and older women (aged 45 or more). Percentages of deaths under 25 years was 24.8% in 1990 and 16.0% in 2019. There was remarkable decline in years lost due to premature death (YLL) rates from 1990 to 2019. While the decline was modest for years lived with disability (YLD) rates. Indirect maternal deaths and other maternal deaths ranked first or second in almost all provinces. Ultimately, there was an evident decrease in MMR along with increase in socio-demographic Index (SDI) from 1990 to 2019 in all provinces and an evident convergence across provinces. CONCLUSION: MMR has declined to levels much lower than Sustainable Development Goals in all provinces. Although there was a convergence in trends, there are still disparities across provinces. The decline in disabilities caused by maternal disorders is not as significant as mortality, which needs further actions.

Neonate, Infant, and Child Mortality in North Africa and Middle East by Cause: An Analysis for the Global Burden of Disease Study 2019.

BACKGROUND: During the past three decades, neonate, infant, and child mortality declined in North Africa and Middle East. However, there is substantial heterogeneity in mortality rates across countries. METHODS: This study is part of the Global Burden of Diseases study (GBD) 2019. We report the number as well as mortality rates for neonates, infants, and children by cause across 21 countries in the region since 1990. RESULTS: Between 1990 and 2019, the neonate mortality rate in the region declined from 31.9 (29.8, 34.0) to 12.2 (11.1, 13.3) per 1000 live births. Respective figures for under 5 mortality rates (U5MRs) were 79.1 (75.7, 82.7) in 1990 and 24.4 (22.3, 26.7) per 1000 live births in 2019. The majority of deaths among children under 5 years were due to under 1 year deaths: 75.9% in 1990 and 81.8% in 2019. Mortality rates in males were higher than females. The mortality rate among neonates ranged from 2.4 (2.1, 2.6) per 1000 live births in Bahrain to 25.0 (21.6, 28.4) in Afghanistan in 2019. Similarly, in 2019, the U5MR ranged from 5.0 (4.2-6.0) per 1000 live births in United Arab Emirates to 55.3 (47.9-63.5) in Afghanistan. Neonatal disorders, congenital birth defects, and lower respiratory infections were the three main causes of neonate, infant, and child mortality in almost all countries in the region. CONCLUSION: In 2019, most countries in this region have achieved the SDG targets for neonate and child mortality. However, there is still substantial heterogeneity across countries.

Sleep disorders as a possible predisposing attack factor in neuromyelitis optica spectrum disorder (NMOSD): A case-control study.

BACKGROUND: Sleep disturbances are common in neuromyelitis optica spectrum disorder (NMOSD) and have a great impact on patients' quality of life. According to a report, there is a 64% prevalence of poor sleep quality in NMOSD patients. Therefore, this study was done to evaluate the effect of sleep disturbances on NMOSD acute exacerbations. MATERIALS AND METHODS: This case-control study was conducted at Sina Hospital in 2019. A total of 60 patients with NMOSD diagnosis were enrolled in the study (30 patients were in the remission phase while 30 patients were hospitalized due to acute attacks). Sleep disorders were evaluated in both groups. Sleep quality was assessed during the last month using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Data were analyzed by SPSS software version 21. RESULTS: Among 60 patients who were evaluated in both the control and attack groups, 86.7% were female. The duration of the disease was 68.23 ±â€¯42.89 months in the control group and 69.83 ±â€¯6.90 in the attack group. The mean age of patients was 34.15 years old. Sleep quality was unfavorable in 30% and 56% of patients in control and attack groups, respectively. There were significant differences between the two groups in sleep latency, habitual sleep efficiency, sleep duration, and sleep disturbance. CONCLUSION: The present study revealed that there was a significant difference in sleep quality between controls and attack patients and could show a direct relationship between sleep disorders and NMOSD attacks.

Bizhan Aarabi and Knowledge Development in Neurotrauma.

Neurotrauma (NT) is one of the common causes of mortality and morbidity. Investigating the role of people who had an impact on the development of knowledge of NT is reasonable. Our aim is to investigate the role of Bizhan Aarabi, professor of Neurosurgery, on the knowledge development in NT. Accordingly, we searched the Scopus database for Bizhan Aarabi on August 8, 2020 and selected papers with at least 10 citations, investigating his impact on NT and details of his publications. He has published 168 papers including original articles, reviews, conference papers, letters, and editorials according to the Scopus databases. There are 112 papers with 10 or more citations. Thirty-eight out of 112 papers (33.9%) were in the first and the highest rank journal: 29 in Neurosurgery and 9 in the Journal of Neurotrauma. Twenty-four papers have the level of evidence (LOE) of "1". Bizhan Arabi developed knowledge in NT especially in the cervical spine/spinal cord trauma and brain injury and his publications are references for spine/neurosurgeons.

Medical history risk factors in primary progressive multiple sclerosis: A case-control study.

Background: The association between medical history and primary progressive multiple sclerosis (PPMS) development has not been well documented in the pertinent literature. The possible association between 23 medical diseases and PPMS occurrence was assessed in the present study. Methods: In order to figure out the possible association between several medical histories and PPMS occurrence, the present population-based case-control study examined 143 PPMS cases in Tehran, Iran, from 2019 to 2020. Diagnosis of PPMS was confirmed by neurologists based on the 2017 McDonald criteria. Sex-matched healthy controls (n = 143) were selected using the random-digit dialing (RDD) technique. Face-to-face and telephone interviews were conducted for gathering the data. The conditional logistic regression model was used to calculate adjusted and unadjusted odds ratio (OR) at a 95% confidence interval (CI). Results: A significant association was found between PPMS development and diseases like depression (OR = 3.12, 95% CI: 1.49-6.53), migraine (OR = 0.19, 95% CI: 0.05-0.67), infectious mononucleosis (OR = 13.16, 95% CI: 2.74-63.17), hypothyroidism (OR = 3.20, 95% CI: 1.23-8.30), and kidney failure (OR = 3.76, 95% CI: 1.41-9.99). Conclusion: Lifetime history of depression, infectious mononucleosis, hypothyroidism, and kidney failure might increase the risk of PPMS development, while individuals with positive history of migraine disease are at lower risk for developing PPMS.

Evaluation of emotional intelligence (EI) in neuromyelitis optica spectrum disorder (NMOSD) patients compared to healthy individuals.

BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) is known as an autoimmune astrocytopathic disorder involving central nervous system (CNS). The aim of this study was to compare Emotional Intelligence (EI) score between NMOSD patients and healthy individuals, and to find out the possible effect of this disease on EI. METHODS: A total of 45 NMOSD participants and 48 healthy individuals were enrolled in this study. Demographic information (e.g., gender and age) of all participants as well as their level of education, and data on the patients' duration of disease were collected. EI of each participant was assessed using Persian version of Emotional Quotient inventory (EQ-i) questionnaire. RESULTS: The mean total EI score was significantly different between the participants and controls (322±36.7 vs 338±31.5, p value<0.03). Compared to controls, patients had a poor performance in 4 of 15 EI subscales including emotional self-awareness (21.29±3.6 vs 22.85±3, p value<0.03), optimism (22.4±4 vs 24.1±3.1, p value<0.03), self-regard (22.7±4.6 vs 24.5±3.4, p value<0.04), and impulse control (16.9±6.5 vs 19.5±5.5, p value<0.05). No difference was found between anti-aquaporin-4 antibody (AQP4-IgG) positive and AQP4-IgG negative patients regarding EI score or its subscale scores, except for self-actualization (p value<0.05). CONCLUSION: Our study showed that EI could be regarded as a tool for understanding emotions, thoughts, and behavior of NMOSD patients. It was implied that taking therapeutic steps could improve the performance of NMOSD patients with EI impairment in social life.

Trend and Projection of Premature Mortality in Iran through 2030: A Modeling Study.

BACKGROUND: Projection of mortality rates is essential for policy making and planning of health services. Premature mortality, as an important index, commonly refers to deaths occurring before 70 years of age. This study was conducted to estimate the trend of premature deaths from 2006-2015 and to project premature deaths for the 2016-2030 period. METHODS: We used national mortality data collected by the Ministry of Health and Medical Education's Deputy of Health, and population data from the Statistical Center of Iran. Mortality and population data were categorized based on sex and 5-year age groups. The Bayesian hierarchical model was used to project future premature mortality rates through 2030. RESULTS: Age-standardized all-cause premature mortality declines from 414.3 per 100000 persons in 2010 to 300.3 per 100000 persons in 2030 (27.5%) for men, and from 230.6 per 100000 persons in 2010 to 197.2 per 100000 persons in 2030 (14.5%) for women. In all age groups, the percent reduction of premature mortality was greater for men than women. CONCLUSION: Overall, it is projected that premature mortality will witness a declining trend in both sexes in Iran. Accordingly, we would expect to achieve less than a third reduction in premature mortality by 2030, which is one of the Sustainable Development Goals.

The correlation between dyslipidemia and cognitive impairment in multiple sclerosis patients.

BACKGROUND: A large number of multiple sclerosis [MS] patients suffer from cognitive dysfunction affecting their routine life in family and society. Investigating modifiable factors for cognition decline and controlling them, could improve the quality of life in MS patients. Therefore, the present study was aimed to evaluate the association between lipid profile components and cognition in MS patients. METHODS: A cross-sectional study was conducted on 50 Relapsing-Remitting MS (RRMS) patients referred to Sina hospital, Tehran, Iran. The definite diagnosis of MS was done based on the revised McDonald criteria. Data on demographic and clinical data of patients were obtained. 5 cc blood samples were taken from all subjects after 10-hour night fasting, and lipid profile components including LDL, HDL, triglyceride, and total cholesterol were evaluated. The Persian version of the Minimal Assessment of Cognitive Functions in MS [MACFIMS] battery was administered to assess the cognitive function. Spearman and Pearson correlation tests were applied to investigate the correlation between lipid profile components and MACFIMS subtests or clinical features of MS patients. RESULTS: The mean age of subjects was equal to 32.26 years old, and 85% of them were women. There was no significant correlation between MACFIMS subtests results with disease duration, patient's disability according to Expanded Disability Status Scale (EDSS), annual attack rate, and disease-modifying drug onset year (P value >0.05). A significant inverse correlation was found between greater serum total cholesterol and lower scores of Symbol Digit Modalities subtest [SDMT] (P value 0.02; r: -0.31), the Delis-Kaplan Executive Function System [DKEFS] sorting (P value 0.01; r: -0.34) and DKEFS-descriptive (P value 0.04; r: -0.28) subtests. This significant inverse correlation was also found in terms of the correlation between higher serum LDL and impairment in the case of DKEFS-sorting score (P value 0.05; r: -0.27), and DKEFS-descriptive score (P value 0.05; r: -0.27). No significant correlation was found in case of serum HDL or triglyceride and MACFIMS subtests (P value >0.05). DISCUSSION: Our findings proposed a possible correlation between the increased serum LDL cholesterol, serum total cholesterol and cognitive dysfunction among MS patients.
