This study aimed to assess the diagnostic validity of this tool. Participants with recent diagnosis of psychiatric disorders were included in the study. They were interviewed using structured clinical interview for diagnostic and statistical manual of mental disorders-5 (SCID-5) and MCMI-IV. The results showed that the Kappa agreement between the MCMI-IV and SCID-5 ranged between 0.23 to 0.39. The discriminant function analysis was conducted to predict personality clusters and other psychiatric disorders. Schizoid and cluster B personality including antisocial, histrionic, and narcissistic personality disorders were predicted by the MCMI-IV scales. Axis I disorders including major depressive disorder, persistent depressive disorder, bipolar mood disorder, and substance use were also predicted by this assessment tool. MCMI-IV scales were, however, not the predictor of other personality and Axis I psychiatric disorders. Sensitivity (23.08% in somatic symptom to 66.7% in drug and alcohol use), specificity (72.52% in generalized anxiety disorder or GAD to 95.61% schizophrenic spectrum), positive predictive probability (PPP) (6.67% in post-traumatic stress disorder or PTSD to 57.35% in cluster B personality) and negative predictor probability (NPP) (80.81% in GAD to 98.15% in PTSD) were estimated. Overall the validity indexes of MCMI-IV improved compared to the previous version of MCMI but these findings suggested that the diagnostic validity of MCMI-IV was not yet acceptable in some clinical scales and further improvements are needed.

Background: The most common manifestation of X‐linked adrenoleukodystrophy (ALD) is a slowly progressive myeloneuropathy, which leads to imbalance and gait disturbances. The variable progression of the disease complicates evaluation of its progression rate. Wearable sensors allow for easy and frequent balance and gait collection. This study reports baseline data from a longitudinal study on the quantitative assessment of balance and gait with wearable sensors and their clinical relevance. Methods: Data were collected from adult patients in two institutions. Postural body sway and gait parameters were measured using accelerometers. Disease severity was measured by the Expanded Disability Severity Scale (EDSS). Falling frequency and quality of life (QOL) were collected in men. The relationship between sway and gait variables and EDSS score, participants' use of a walking aid, and falling frequency was evaluated. Results: One hundred twenty individuals with ALD were included. Sway variables significantly differentiate participants' assistive device use. Sway and gait variables were correlated to the EDSS in both sexes. Both gait speed and sway were correlated with falling frequency in men from one institution. Select QOL subscores were correlated with the EDSS in males from one institution. Accelerometry generated comparable results across sites. Discussion: This study confirms the clinical correlation between spinal cord disease and imbalance and gait in ALD. For the first time, this study shows clinically meaningful relationships for sway and gait with use of an assistive device, falling frequency and QOL. Wearable accelerometers are a valid means to measure sway and gait in ALD. These measures are promising outcomes for clinical trial designs to assess myeloneuropathy in ALD and to monitor disease progression in individuals. [ABSTRACT FROM AUTHOR]

Interpersonal violence (IPV) is a major public health concern with a significant impact on physical and mental health. This study was designed to evaluate age–sex-specific IPV mortality trends and the assault mechanisms (firearm, sharp objects, and other means), at national and provincial levels, in Iran. We used the Iranian Death Registration System (DRS) and the population and housing censuses in this analysis. Spatio-temporal and Gaussian Process Regression methods were used to adjust for inconsistencies at the provincial level and to integrate data from various sources. After assessing their validity, all records were reclassified according to the International Classification of Diseases, 10th Revision (ICD-10). All ICD-10 codes were then mapped to Global Burden of Disease (GBD) 2013 coding. More than 700 individuals died due to IPV in 1990 and more than twice this number in 2015. The IPV mortality age-standardized rate, per 100,000, increased from 1.62 (95% Uncertainty Interval [UI] = [0.96, 2.75]) in 1990 to 1.81 [1.15, 2.89] in 2015. Among females, the age-standardized mortality rate at national level per 100,000 due to IPV was 1.27 [0.66, 2.43] in 1990 and decreased to 1.08 [0.60, 1.96] in 2015. Among males, the age-standardized mortality rate was 1.96 [1.25, 3.09] in 1990 rising to 2.54 [1.70, 3.82] in 2015. Data from provinces revealed that during the period of our study, Hormozgan province had the largest increase of IPV among females, and Fars province had the largest increase of IPV among males. Conversely, the largest decrease was detected in West Azarbaijan and Qom provinces in females and males, respectively. This study showed a wide variation in the incidence and trends of IPV in Iran by age, sex, and location. The study has provided valuable information to reduce the burden of IPV in Iran and a means to monitor future progress through repeated analyses of the trends. [ABSTRACT FROM AUTHOR]

Background: Few migraine preventive agents have been assessed in a pediatric population. We evaluated the safety and efficacy of cinnarizine and sodium valproate for migraine prophylaxis in children and adolescents.Methods: We carried out a randomized double-blind placebo-controlled trial in the Children's Medical Center and Sina hospital, Tehran, Iran. Eligible participants were randomly assigned in 1:1:1 ratio via interactive web response system to receive either cinnarizine, sodium valproate, or placebo. The primary endpoints were the mean change in frequency and intensity of migraine attacks from baseline to the last 4 weeks of trial. The secondary endpoint was the efficacy of each drug in the prevention of migraine. The drug was considered effective if it decreased migraine frequency by more than 50% in the double-blind phase compared with the baseline. Safety endpoint was adverse effects that were reported by children or their parents.Results: A total of 158 children participated. The frequency of migraine attacks significantly reduced compared to baseline in cinnarizine (difference: -8.0; 95% confidence interval (CI): -9.3 to -6.6), sodium valproate (difference: -8.3; 95% confidence interval: -9.3 to -7.2), and placebo (difference: -4.4; 95% confidence interval: -5.4 to -3.4) arms. The decrease was statistically greater in cinnarizine (difference: -3.6; 95% confidence interval: -5.5 to -1.6) and sodium valproate (difference: -3.9; 95% confidence interval: -5.8 to -1.9) arms, compared to placebo group. Children in all groups had significant reduction in intensity of episodes compared to baseline (cinnarizine: -4.6; 95% confidence interval: -5.2 to -4.0; sodium valproate: -4.0; 95% confidence interval: -4.8 to -3.3; placebo: -2.6; 95% confidence interval: -3.4 to -1.8). The decrease was statistically greater in cinnarizine (difference: -2.0; 95% confidence interval: -3.2 to -0.8) and sodium valproate (difference: -1.5; 95% confidence interval: -2.7 to -0.3) arms, compared to the placebo group. Seventy-one percent of individuals in the cinnarizine group, 66% of cases in the sodium valproate group, and 42% of people in the placebo arm reported more than 50% reduction in episodes at the end of the trial. The odds ratio for >50% responder rate was 3.5 (98.3% confidence interval: 1.3 to 9.3) for cinnarizine versus placebo and 2.7 (98.3% confidence interval: 1.0 to 6.9) for sodium valproate versus placebo. Nine individuals reported adverse effects (three in cinnarizine, five in sodium valproate, and one in the placebo group) and one case in the sodium valproate group discontinued the therapy due to severe sedation.Conclusion: Cinnarizine and sodium valproate could be useful in migraine prophylaxis in children and adolescents.
