Neuroimaging assessment of facility-bound severely-affected MS reveals the critical role of cortical gray matter pathology: results from the CASA-MS case-controlled study.

BACKGROUND: A subgroup of people with multiple sclerosis (pwMS) will develop severe disability. The pathophysiology underlying severe MS is unknown. The comprehensive assessment of severely affected MS (CASA-MS) was a case-controlled study that compared severely disabled in skilled nursing (SD/SN) (EDSS ≥ 7.0) to less-disabled (EDSS 3.0-6.5) community dwelling (CD) progressive pwMS, matched on age-, sex- and disease-duration (DDM). OBJECTIVES: To identify neuroimaging and molecular biomarker characteristics that distinguish SD/SN from DDM-CD progressive pwMS. METHODS: This study was carried at SN facility and at a tertiary MS center. The study collected clinical, molecular (serum neurofilament light chain, sNfL and glial acidic fibrillary protein, sGFAP) and MRI quantitative lesion-, brain volume-, and tissue integrity-derived measures. Statistical analyses were controlled for multiple comparisons. RESULTS: 42 SD/SN and 42 DDM-CD were enrolled. SD/SN pwMS showed significantly lower cortical volume (CV) (p < 0.001, d = 1.375) and thalamic volume (p < 0.001, d = 0.972) compared to DDM-CD pwMS. In a logistic stepwise regression model, the SD/SN pwMS were best differentiated from the DDM-CD pwMS by lower CV (p < 0.001) as the only significant predictor, with the accuracy of 82.3%. No significant differences between the two groups were observed for medulla oblongata volume, a proxy for spinal cord atrophy and white matter lesion burden, while there was a statistical trend for numerically higher sGFAP in SD/SN pwMS. CONCLUSIONS: The CASA-MS study showed significantly more gray matter atrophy in severe compared to less-severe progressive MS.

Dynamic disability measures decrease the clinico-radiological gap in people with severely affected multiple sclerosis.

BACKGROUND: Expanded Disability Status Scale (EDSS) is limited when utilized in highly disabled people with multiple sclerosis (pwMS). OBJETIVE: To explore the relationship between disability measures and MRI outcomes in severely-affected pwMS. METHODS: PwMS recruited from The Boston Home (TBH), a specialized residential facility for severly-affected pwMS and University at Buffalo (UB) MS Center were assessed using EDSS, MS Severity Scale, age-related MSS, Scripps Neurological Rating Scale (SNRS) and Combinatorial Weight-Adjusted Disability Score (CombiWISE). In all scores except SNRS, higher score indicates greater disability. MRI measures of T1, T2-lesion volume (LV), whole brain, gray matter, medulla oblongata and thalamic volumes (WBV, GMV, MOV, TV) and thalamic dysconnectivity were obtained. RESULTS: Greatest disability differences between the TBH and UB pwMS were in SNRS (24.4 vs 71.9, p < 0.001, Cohen's d = 4.05) and CombiWISE (82.3 vs. 38.9, p < 0.001, Cohen's d = 4.02). In combined analysis of all pwMS, worse SNRS scores were correlated with worse MRI pathology in 8 out of 9 outcomes. EDSS only with 3 measures (GMV, MOV and TV). In severely-affected pwMS, SNRS was associated with T1-LV, T2-LV and WBV (not surviving false discovery rate (FDR) correction for multiple comparisons) whereas EDSS did not. CONCLUSION: Granular and dynamic disability measures may bridge the clinico-radiologcal gap present in severely affected pwMS.

Policies for Individuals With Autism: Gaps, Research, and Recommendations.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by social, behavioral, and learning challenges. Individuals with autism and their families often struggle to get an appropriate diagnosis and continuation of specialty services, including general healthcare, mental health and transition services, special education, employment, and social and emotional support. This paper presents information about the current policies and support mechanisms that exist to help these individuals and their families. This paper identifies the gaps and recommends areas of improvement based on evidence-based research and current data. ASD is a lifelong disability without a cure, but by constructing robust policies and providing enhanced support, the quality of lives of those with ASD and their families can be improved.

Obstacles to diagnostic investigation of a child with comorbid psychiatric conditions.

Presented here is the unique case of diagnostic investigation for a 16 year old male presenting in an acute state of apparent psychosis. The patient had a long history of previous specialist work-ups, tentative diagnoses, multiple emergency department admissions, and medication trials, all of which failed to produce significant lasting relief. While initial encounters diagnostically centered on autoimmune encephalitis, comprehensive work-ups always drove the differential towards a likely psychiatric disorder. Despite this consistent professional opinion, tentative diagnosis of schizophrenia with underlying Autism Spectrum Disorder was delayed for many years, due to a variety of complicating factors. Overall, this case highlights many different considerations that might assist in avoiding a protracted road to diagnosis, including navigating the obstacles that parental interaction with a complex healthcare system can pose during diagnostic evaluation and recommended treatment as well as, the role of re-interpreting past test results within the context of new literature, and the complexities of diagnosing comorbid psychiatric conditions.

Frozen conflict in the midst of a global pandemic: potential impact on mental health in Armenian border communities.

Armenia has been in a conflict with its neighbor, Azerbaijan, since 1988. Civilians in Tavush Province are regularly affected by ceasefire violations along the armed border with recent escalations further threatening the population's safety. In the midst of the COVID-19 pandemic, concerns regarding the mental health of border village residents in Armenia are prevalent. We present context-related factors of psychiatric illness, the prevalence of mental health disorders, and the state of mental health services in Armenia. We recommend directing greater attention towards the mental health status of civilians residing in conflict zones during the ongoing COVID-19 pandemic.

Community Violence, PTSD, Hopelessness, Substance Use, and Perpetuation of Violence in an Urban Environment.

We investigated the relationships among chronic violence exposure, post-traumatic stress disorder (PTSD) symptom severity, hopelessness, substance use, and perpetuation of violence to facilitate the development of trauma-related interventions for residents of Newark, NJ. A convenience sample of Newark residents (N = 153) was recruited from community centers during various events in 2016-2017. Anonymous, self-report survey measures included a PTSD screen (PCL-C), Beck's Hopelessness Scale, the CAGE questionnaire, and a CDC Health Behavior Scale. Descriptive statistics, Pearson's correlations, Chi square analyses, logistic, and linear regressions were used for analysis. Thirty percent (95% CI [22.7, 37.4]) of our sample screened positive for PTSD. Drug and alcohol use, fighting, and hopelessness were related to severity of PTSD symptoms (p < 0.05). Female gender, CAGE scores, and hopelessness predicted the severity of PTSD symptoms (R2 = 0.354, p < 0.05). Our data has informed the development of a resilience support group currently in the pilot stage for community members.

Mood disorders of childhood and adolescence in a low-income, urban community: A retrospective chart review.

BACKGROUND: Our goal was to determine the risk factors that most correlated with mood disorder diagnoses in children in a low-income, urban community. METHODS: We conducted a retrospective chart review of 174 patients age 6 to 18 who were seen between November 2016 and July 2017 at the University Hospital Psychiatric Pediatric Emergency Services in Newark, New Jersey, United States. RESULTS: Bivariate and multivariate analyses revealed that increasing age, female sex, exposure to trauma, and family history of psychiatric illness were significantly associated with mood disorders in our sample. CONCLUSIONS: The correlation of mood disorders with trauma and family psychiatric history is of particular significance in our sample. In low-income cities with high crime rates and a lack of positive influences, children often have difficulty obtaining the skills to cope with trauma in a healthy manner. Also, the paucity of resources in these communities prevents family members from getting the mental health treatment that they need, further inhibiting children in these families from developing healthy habits. Mental health treatment must be targeted towards entire families and not just in children with mood disorders in order to most effectively improve the mental health outcomes of those who grow up in these communities.

A Course on Terror Medicine: Content and Evaluations.

INTRODUCTION: The development of medical school courses on medical responses for disaster victims has been deemed largely inadequate. To address this gap, a 2-week elective course on Terror Medicine (a field related to Disaster and Emergency Medicine) has been designed for fourth year students at Rutgers New Jersey Medical School in Newark, New Jersey (USA). This elective is part of an overall curricular plan to broaden exposure to topics related to Terror Medicine throughout the undergraduate medical education. RATIONALE: A course on Terror Medicine necessarily includes key aspects of Disaster and Emergency Medicine, though the converse is not the case. Courses on Disaster Medicine may not address features distinctively associated with a terror attack. Thus, a terror-related focus not only assures attention to this important subject but to accidental or naturally occurring incidents as well. METHODS: The course, implemented in 2014, uses a variety of teaching modalities including lectures, videos, and tabletop and hands-on simulation exercises. The subject matter includes biological and chemical terrorism, disaster management, mechanisms of injury, and psychiatry. This report outlines the elective's goals and objectives, describes the course syllabus, and presents outcomes based on student evaluations of the initial iterations of the elective offering. RESULTS: All students rated the course as "excellent" or "very good." Evaluations included enthusiastic comments about the content, methods of instruction, and especially the value of the simulation exercises. Students also reported finding the course novel and engaging. CONCLUSION: An elective course on Terror Medicine, as described, is shown to be feasible and successful. The student participants found the content relevant to their education and the manner of instruction effective. This course may serve as a model for other medical schools contemplating the expansion or inclusion of Terror Medicine-related topics in their curriculum.

Medical Student Education in State Psychiatric Hospitals: A Survey of US State Hospitals.

OBJECTIVE: State hospitals may be underutilized in medical education. US state psychiatric hospitals were surveyed on current and potential psychiatry medical student education. METHODS: A 10-item questionnaire, with multiple response formats, was sent to identified hospitals in late 2012. RESULTS: Ninety-seven of 221 hospitals contacted responded. Fifty-three (55%) reported current medical student education programs, including 27 clinical clerkship rotations. Education and training in other disciplines was prevalent in hospitals both with and without medical students. The large majority of responders expressed enthusiasm about medical education. The most frequent reported barrier to new programs was geographic distance from the school. Limited resources were limiting factors for hospitals with and without current programs. CONCLUSIONS: Only a minority of US state hospitals may be involved in medical student education. While barriers such as geographic distance may be difficult to overcome, responses suggest opportunities for expanding medical education in the state psychiatric hospitals.

Cardiovascular risk factors are associated with increased lesion burden and brain atrophy in multiple sclerosis.

BACKGROUND: Cardiovascular (CV) risk factors have been associated with changes in clinical outcomes in patients with multiple sclerosis (MS). OBJECTIVES: To investigate the frequency of CV risks in patients with MS and their association with MRI outcomes. METHODS: In a prospective study, 326 patients with relapsing-remitting MS and 163 patients with progressive MS, 61 patients with clinically isolated syndrome (CIS) and 175 healthy controls (HCs) were screened for CV risks and scanned on a 3T MRI scanner. Examined CV risks included hypertension, heart disease, smoking, overweight/obesity and type 1 diabetes. MRI measures assessed lesion volumes (LVs) and brain atrophy. Association between individual or multiple CV risks and MRI outcomes was examined adjusting for age, sex, race, disease duration and treatment status. RESULTS: Patients with MS showed increased frequency of smoking (51.7% vs 36.5%, p = 0.001) and hypertension (33.9% vs 24.7%, p=0.035) compared with HCs. In total, 49.9% of patients with MS and 36% of HCs showed ≥ 2 CV risks (p = 0.003), while the frequency of ≥ 3 CV risks was 18.8% in the MS group and 8.6% in the HCs group (p = 0.002). In patients with MS, hypertension and heart disease were associated with decreased grey matter (GM) and cortical volumes (p < 0.05), while overweight/obesity was associated with increased T1-LV (p < 0.39) and smoking with decreased whole brain volume (p = 0.049). Increased lateral ventricle volume was associated with heart disease (p = 0.029) in CIS. CONCLUSIONS: Patients with MS with one or more CV risks showed increased lesion burden and more advanced brain atrophy.

Immunologic and MRI markers of the therapeutic effect of IFN-ß-1a in relapsing-remitting MS.

OBJECTIVES: To assess potential roles of effector cells and immunologic markers in demyelinating CNS lesion formation, and their modulation by interferon ß-1a (IFN-ß-1a). METHODS: Twenty-three patients with relapsing-remitting multiple sclerosis (RRMS) received IFN-ß-1a for 6 months. Immunologic marker results were correlated with brain MRI lesion volumes, and volumes of normal-appearing brain tissue (NABT) with decreasing or increasing voxel-wise magnetization transfer ratio (VW-MTR), suggestive of demyelination and remyelination, respectively. RESULTS: Baseline expression of Th22 cell transcription factor aryl hydrocarbon receptor (AHR) and interleukin (IL)-17F, and percentages of IL-22-expressing CD4(+) and CD8(+) cells, were significantly higher in patients vs 15 healthy controls; IL-4 in CD4(+) cells was lower. Baseline percentage of IL-22-producing CD8(+) cells positively correlated with T2 lesion volumes, while percentage of IL-17A-producing CD8(+) cells positively correlated with T2 and T1 lesion volumes. IFN-ß-1a induced reductions in transcription factor AHR, T-bet, and retinoic acid-related orphan nuclear hormone receptor C (RORc) gene expression, while it increased GATA3's expression in CD4(+) cells. Percentages of IL-22-, IL-17A-, and IL-17F-expressing T cells significantly decreased following treatment. Increased percentages of IL-10-expressing CD4(+) and CD8(+) cells correlated with greater NABT volume with increasing VW-MTR, while decreased percentage of IL-17F-expressing CD4(+) cells positively correlated with decreased NABT volume with decreasing VW-MTR. CONCLUSIONS: Findings indicate that IFN-ß-1a suppresses Th22 and Th17 cell responses, which were associated with decreased MRI-detectable demyelination. CLASSIFICATION OF EVIDENCE: This pilot study provides Class III evidence that reduced Th22 and Th17 responses are associated with decreased demyelination following IFN-ß-1a treatment in patients with RRMS.

Immunological and short-term brain volume changes in relapsing forms of multiple sclerosis treated with interferon beta-1a subcutaneously three times weekly: an open-label two-arm trial.

BACKGROUND: Brain volume atrophy is observed in relapsing-remitting multiple sclerosis (RRMS). METHODS: Brain volume changes were evaluated in 23 patients with RRMS treated with interferon ß-1a 44 µg given subcutaneously (SC) three times a week (tiw) and 15 healthy controls. Percentages of whole brain and tissue-specific volume change were measured from baseline (0 months) to 3 months, from 3 to 6 months, and from baseline to 6 months using SIENAX Multi Time Point (SX-MTP) algorithms. Immunological status of patients was also determined and correlations between subsets of T cells and changes in brain volume were assessed. RESULTS: Interferon ß-1a 44 µg SC tiw in 23 patients with RRMS resulted in significant reductions in whole brain and gray matter tissue volume early in the treatment course (baseline to 3 months; mean change; -0.95%; P = 0.030, -1.52%; P = 0.004, respectively), suggesting a short-term treatment-induced pseudoatrophy effect. From baseline to 6 months, there were significant correlations observed between decreased T- cell expression of IL-17 F and decreased whole brain and brain tissue-specific volume. CONCLUSIONS: These findings are consistent with the interpretation of the pseudoatrophy effect as resolution of inflammation following treatment initiation with interferon ß-1a 44 µg SC tiw, rather than disease-related tissue loss. TRIAL REGISTRATION: ClinicalTrials.gov; NCT01085318.

A pilot, longitudinal, 24-week study to evaluate the effect of interferon beta-1a subcutaneous on changes in susceptibility-weighted imaging-filtered phase assessment of lesions and subcortical deep-gray matter in relapsing-remitting multiple sclerosis.

BACKGROUND: Studies have shown a relationship between increased iron content and clinical progression, cognitive impairment, and brain atrophy in patients with multiple sclerosis. Altered phase, as determined by susceptibility-weighted imaging (SWI), can potentially capture iron content changes. OBJECTIVE: The objective of this study was to investigate phase changes in white matter (WM) lesions and subcortical deep-gray matter (SDGM) of patients with relapsing-remitting (RR) MS treated with interferon beta-1a administered subcutaneously versus untreated healthy controls (HCs). METHODS: We conducted a 24-week, nonrandomized, open-label pilot study of 23 patients with RRMS receiving interferon beta-1a administered subcutaneously and 15 HCs. Patients were imaged on a 3T scanner at baseline, 12, and 24 weeks; changes in phase behavior in WM lesions and regional SDGM [mean phase of low-phase voxels (MP-LPV)], and in SDGM volumes, were measured. Between- and within-group changes were tested using nonparametric statistics adjusted for multiple comparisons. RESULTS: The number (p = 0.003) and volume (p < 0.001) of phase WM lesions both significantly decreased among RRMS patients over 24 weeks. At baseline, MP-LPV was lower (suggestive of greater iron content) in total SDGM among RRMS patients versus HCs (p = 0.002). Week 24 MP-LPV changes from baseline were not significantly different between groups in total SDGM or any region except the putamen (-0.0025 radians in RRMS patients versus 0.0035 radians in HCs; p = 0.041). CONCLUSIONS: Over 24 weeks, phase lesions were reduced significantly in the RRMS group. These preliminary results suggest that SWI-filtered phase may become a useful tool for monitoring RRMS disease activity.

Associations between changes in ferritin levels and susceptibility-weighted imaging filtered phase in patients with relapsing-remitting multiple sclerosis over 24 weeks of therapy with subcutaneous interferon beta-1a three times weekly.

Subanalysis of a pilot study (NCT01085318) assessed correlations between serum ferritin and imaging assessments in relapsing-remitting multiple sclerosis patients (n = 23) receiving 44 µg interferon beta-1a subcutaneously three times weekly. At baseline, 12, and 24 weeks, mean ferritin was 75, 127 (p < 0.001 vs baseline), and 101 (p=0.020 vs baseline) ng/mL. No relationship between ferritin and susceptibility-weighted imaging (SWI)-filtered phase of subcortical deep gray matter was found. Increasing ferritin correlated with decreasing lesion numbers on both fluid attenuated inversion recovery and SWI phase at 12 weeks (r = -0.62; p = 0.003; n = 21), and with decreasing gadolinium-enhancing lesion volume at 24 weeks (r = -0.71; p = 0.050; n = 8).

Terror medicine as part of the medical school curriculum.

Terror medicine, a field related to emergency and disaster medicine, focuses on medical issues ranging from preparedness to psychological manifestations specifically associated with terrorist attacks. Calls to teach aspects of the subject in American medical schools surged after the 2001 jetliner and anthrax attacks. Although the threat of terrorism persists, terror medicine is still addressed erratically if at all in most medical schools. This paper suggests a template for incorporating the subject throughout a 4-year medical curriculum. The instructional framework culminates in a short course for fourth year students, such as one recently introduced at Rutgers New Jersey Medical School, Newark, NJ, USA. The proposed 4-year Rutgers curriculum serves as a model that could assist other medical schools contemplating the inclusion of terror medicine in pre-clerkship and clerkship training.

Prospective randomized trial of venous angioplasty in MS (PREMiSe).

OBJECTIVE: We report the results of the investigation of safety and efficacy of venous angioplasty in patients with multiple sclerosis (MS) with findings of extracranial venous anomalies, considered hallmarks of chronic cerebrospinal venous insufficiency (CCSVI), in a 2-phase study (ClinicalTrials.gov NCT01450072). METHODS: Phase 1 was an open-label safety study (10 patients); phase 2 was sham-controlled, randomized, and double-blind (10 sham procedure, 9 treated). All study patients fulfilled venous hemodynamic screening criteria indicative of CCSVI. Assessment was at 1, 3, and 6 months postprocedure with MRI, clinical, and hemodynamic outcomes. Primary endpoints were safety at 24 hours and 1 month, venous outflow restoration >75% at 1 month, and effect of angioplasty on new lesion activity and relapse rate over 6 months. Secondary endpoints included changes in disability, brain volume, cognitive tests, and quality of life. RESULTS: No perioperative complications were noted; however, one patient with history of syncope was diagnosed with episodic bradycardia requiring placement of a pacemaker before discharge. Doppler evidence-based venous hemodynamic insufficiency severity score (VHISS) was reduced >75% compared to baseline in phase 1 (at 1 month) but not phase 2. In phase 2, higher MRI activity (cumulative number of new contrast-enhancing lesions [19 vs 3, p = 0.062] and new T2 lesions [17 vs 3, p = 0.066]) and relapse activity (4 vs 1, p = 0.389) were identified as nonsignificant trends in the treated vs sham arm over 6 months. Using analysis of covariance, significant cumulative new T2 lesions were related to larger VHISS decrease (p = 0.028) and angioplasty (p = 0.01) over the follow-up. No differences in other endpoints were detected. CONCLUSION: Venous angioplasty is not an effective treatment for MS over the short term and may exacerbate underlying disease activity. CLASSIFICATION OF EVIDENCE: This is a Class I study demonstrating that clinical and imaging outcomes are no better or worse in patients with MS identified with venous outflow restriction who receive venous angioplasty compared to sham controls who do not receive angioplasty. This study also includes a Class IV phase 1 study of safety in 10 patients receiving the angioplasty procedure.

Effect of treatment with interferon beta-1a on changes in voxel-wise magnetization transfer ratio in normal appearing brain tissue and lesions of patients with relapsing-remitting multiple sclerosis: a 24-week, controlled pilot study.

BACKGROUND: This pilot study investigated changes in remyelinating and demyelinating activity in normal appearing brain tissue (NABT) and lesions, by using voxel-wise magnetization transfer ratio (VW-MTR), in patients with relapsing-remitting multiple sclerosis (RRMS) receiving interferon beta-1a 44 mcg subcutaneously (IFN ß-1a SC) three times weekly versus healthy controls (HCs) (NCT01085318). METHODS: Increasing (suggestive of remyelination) and decreasing (suggestive of demyelination) VW-MTR changes in NABT and in T2, T1 and gadolinium (Gd)-enhancing lesion volume were measured over 24 weeks in 23 patients treated with IFN ß-1a SC and in 15 HCs (where applicable). VW-MTR changes were tested using the Wilcoxon signed-rank or Wilcoxon rank-sum test. RESULTS: A trend for greater volume of NABT with increasing VW-MTR at 24 weeks was observed for patients versus HCs (median [range] 1206 [0-15278]; 342 [0-951] mm3; p = 0.061). NABT volume with increasing VW-MTR at 12 weeks was significantly greater in patients than in HCs (852 [6-11577]; 360 [0-1755] mm3; p = 0.028). Similar findings were detected for lesion volumes. Two patients with notably high numbers of Gd-enhancing lesions at baseline had a markedly greater volume of tissue with increasing VW-MTR compared with other patients. Volume of NABT tissue with decreasing VW-MTR was significantly greater in patients versus HCs at 24 weeks (942 [0-6141]; 297 [0-852] mm3; p<0.001). CONCLUSIONS: The significant change in NABT volume with increasing VW-MTR at 12 weeks suggests that active remyelination in patients with RRMS may occur during treatment with IFN ß-1a SC. Findings from two patients with the highest number of Gd-enhancing lesions at baseline suggest that extensive remyelination in NABT may occur in patients with high disease activity. Tissue volume with decreasing VW-MTR was greater in patients than in HCs, despite treatment, validating the sensitivity of this technique for detecting MS disease activity.
