A smartphone sensor-based digital outcome assessment of multiple sclerosis.

BACKGROUND: Sensor-based monitoring tools fill a critical gap in multiple sclerosis (MS) research and clinical care. OBJECTIVE: The aim of this study is to assess performance characteristics of the Floodlight Proof-of-Concept (PoC) app. METHODS: In a 24-week study (clinicaltrials.gov: NCT02952911), smartphone-based active tests and passive monitoring assessed cognition (electronic Symbol Digit Modalities Test), upper extremity function (Pinching Test, Draw a Shape Test), and gait and balance (Static Balance Test, U-Turn Test, Walk Test, Passive Monitoring). Intraclass correlation coefficients (ICCs) and age- or sex-adjusted Spearman's rank correlation determined test-retest reliability and correlations with clinical and magnetic resonance imaging (MRI) outcome measures, respectively. RESULTS: Seventy-six people with MS (PwMS) and 25 healthy controls were enrolled. In PwMS, ICCs were moderate-to-good (ICC(2,1) = 0.61-0.85) across tests. Correlations with domain-specific standard clinical disability measures were significant for all tests in the cognitive (r = 0.82, p < 0.001), upper extremity function (|r|= 0.40-0.64, all p < 0.001), and gait and balance domains (r = -0.25 to -0.52, all p < 0.05; except for Static Balance Test: r = -0.20, p > 0.05). Most tests also correlated with Expanded Disability Status Scale, 29-item Multiple Sclerosis Impact Scale items or subscales, and/or normalized brain volume. CONCLUSION: The Floodlight PoC app captures reliable and clinically relevant measures of functional impairment in MS, supporting its potential use in clinical research and practice.

Adherence and Satisfaction of Smartphone- and Smartwatch-Based Remote Active Testing and Passive Monitoring in People With Multiple Sclerosis: Nonrandomized Interventional Feasibility Study.

BACKGROUND: Current clinical assessments of people with multiple sclerosis are episodic and may miss critical features of functional fluctuations between visits. OBJECTIVE: The goal of the research was to assess the feasibility of remote active testing and passive monitoring using smartphones and smartwatch technology in people with multiple sclerosis with respect to adherence and satisfaction with the FLOODLIGHT test battery. METHODS: People with multiple sclerosis (aged 20 to 57 years; Expanded Disability Status Scale 0-5.5; n=76) and healthy controls (n=25) performed the FLOODLIGHT test battery, comprising active tests (daily, weekly, every two weeks, or on demand) and passive monitoring (sensor-based gait and mobility) for 24 weeks using a smartphone and smartwatch. The primary analysis assessed adherence (proportion of weeks with at least 3 days of completed testing and 4 hours per day passive monitoring) and questionnaire-based satisfaction. In-clinic assessments (clinical and magnetic resonance imaging) were performed. RESULTS: People with multiple sclerosis showed 70% (16.68/24 weeks) adherence to active tests and 79% (18.89/24 weeks) to passive monitoring; satisfaction score was on average 73.7 out of 100. Neither adherence nor satisfaction was associated with specific population characteristics. Test-battery assessments had an at least acceptable impact on daily activities in over 80% (61/72) of people with multiple sclerosis. CONCLUSIONS: People with multiple sclerosis were engaged and satisfied with the FLOODLIGHT test battery. FLOODLIGHT sensor-based measures may enable continuous assessment of multiple sclerosis disease in clinical trials and real-world settings.

Use of smartphone-based remote assessments of multiple sclerosis in Floodlight Open, a global, prospective, open-access study.

Floodlight Open was a global, open-access, digital-only study designed to understand the drivers and barriers in deployment and use of a smartphone app in a naturalistic setting and broad study population of people with and without multiple sclerosis (MS). The study utilised the Floodlight Open app: a 'bring-your-own-device' solution that remotely measures a user's mood, cognition, hand motor function, and gait and postural stability via smartphone sensor-based tests requiring active user input ('active tests'). Levels of mobility of study participants ('life-space measurement') were passively measured. Study data from these tests were made available via an open-access platform. Data from 1350 participants with self-declared MS and 1133 participants with self-declared non-MS from 17 countries across four continents were included in this report. Overall, MS participants provided active test data for a mean duration of 5.6 weeks or a mean duration of 19 non-consecutive days. This duration increased among MS participants who persisted beyond the first week to a mean of 10.3 weeks or 36.5 non-consecutive days. Passively collected life-space measurement data were generated by MS participants for a mean duration of 9.8 weeks or 50.6 non-consecutive days. This duration increased to 16.3 weeks/85.1 non-consecutive days among MS participants who persisted beyond the first week. Older age, self-declared MS disease status, and clinical supervision as part of concomitant clinical research were all significantly associated with higher persistence of the use of the Floodlight Open app. MS participants performed significantly worse than non-MS participants on four out of seven active tests. The findings from this multinational study inform future research to improve the dynamics of persistence of use of digital monitoring tools and further highlight challenges and opportunities in applying them to support MS clinical care.

Intensive nurse-led follow-up in primary care to improve self-management and compliance behaviour after myocardial infarction.

AIMS AND OBJECTIVES: To assess the effects of intensive follow-up by primary care nurses on cardiovascular disease self-management and compliance behaviours after myocardial infarction. BACKGROUND: Although cardiovascular disease prevention and cardiac rehabilitation take place in hospital settings, a nurse-led approach is necessary in primary care during the first few months after a myocardial infarction. Therefore, it is important to assess self-management of cardiovascular disease and levels of compliance with the prescribed diet, physical activity, and medication. DESIGN: The study used a multicentre, quasi-experimental, pre-post design without a control group. METHODS: Patients with acute coronary syndrome from 40 healthcare facilities were included in the study. A total of 212 patients participated in a programme including 11 interventions during the first 12-18 months after myocardial infarction. The following Nursing Outcomes Classification (NOC) outcomes were assessed at baseline and at the end of the intervention: Self-management: Cardiac Disease (1617) and Compliance Behaviour: Prescribed Diet (1622), Compliance Behaviour: Prescribed Activity (1632), and Compliance Behaviour: Prescribed Medication (1623). Marjory Gordon's functional health patterns and a self-care notebook were used in each intervention. Pre-post intervention means were compared using Student's t-tests for related samples. The results of the study are reported in compliance with the TREND Statement. RESULTS: A total of 132 patients completed the intervention. The indicators for each NOC outcome and the variations in scores before and after the intensive follow-up showed a statistically significant improvement (p-value = 0.000). Compliance Behaviour: Prescribed Diet (pre = 3.7; post = 4.1); Compliance Behaviour: Prescribed Activity (pre = 3.9; post = 4.3); Compliance Behaviour: Prescribed Medication (pre = 3.9; post = 4.7). CONCLUSION: Intensive, immediate follow-up after myocardial infarction improves compliance behaviours and self-management of heart disease. A combined self-care and family care approach should be encouraged to empower post-myocardial infarction patients. To facilitate patients' self-efficacy, the use of health education tools such as a cardiovascular self-care notebook can also be helpful. RELEVANCE TO CLINICAL PRACTICE: This study highlights the benefits of intensive, protocolised, comprehensive patient follow-up in primary care during the first few months after an acute myocardial infarction (AMI). Primary care nurses train patients in cardiovascular self-care. PATIENT OR PUBLIC CONTRIBUTION: Patients were not involved in either the design or the carrying out of the study. However, at the end of the study, they participated in an evaluation process about the utility of the research study and their satisfaction with it. This process was carried out using an ad hoc survey consisting of 10 questions assessing the nursing care and follow-up inputs that were received.

Quality of care in systemic lupus erythematosus: application of quality measures to understand gaps in care.

BACKGROUND: Systemic lupus erythematosus (SLE) affects 1 in 2500 Americans and is associated with significant morbidity and mortality. The recent development of SLE quality measures provides an opportunity to understand gaps in clinical care and to identify modifiable factors associated with variations in quality. OBJECTIVE: To evaluate performance on SLE quality measures as well as differences in quality of care by demographic, socioeconomic, disease, and health system characteristics. DESIGN AND PATIENTS: Cross-sectional analysis of data derived from the Lupus Outcomes Study, a prospective, longitudinal study of 814 individuals. Principal data collection was through annual structured telephone surveys between 2009-2010. Data on 13 SLE quality measures was collected. We used regression models to estimate demographic, socioeconomic, disease, and health system characteristics associated with performance on individual and overall quality measures. OUTCOME MEASURES: Performance on each quality measure and overall performance on all measures for which participants were eligible (pass rate). RESULTS: Participants were eligible for a mean of five measures (range 2-12). Performance varied from 29 % (assessment of cardiovascular risk factors) to 90 % (sun avoidance counseling). The overall pass rate was 65 % (95 % CI 64 %, 65 %). In unadjusted analyses, younger age, minority race/ethnicity, poverty, shorter disease duration, fewer physician visits, and lack of health insurance, were associated with lower pass rates. Receiving care in public sector managed care organizations was associated with higher pass rates. After adjustment, younger age, having fewer physician visits and lacking health insurance remained significantly associated with lower performance; receiving care in public sector managed care organizations remained associated with higher performance. CONCLUSIONS: We identified a number of gaps in clinical care for SLE. Factors associated with the health care system, including presence and type of health insurance, were the primary determinants of performance on quality measures in SLE.

Generating real-world data from health records: design of a patient-centric study in multiple sclerosis using a commercial health records platform.

OBJECTIVE: The FlywheelMS study will explore the use of a real-world health record data set generated by PicnicHealth, a patient-centric health records platform, to improve understanding of disease course and patterns of care for patients with multiple sclerosis (MS). MATERIALS AND METHODS: The FlywheelMS study aims to enroll 5000 adults with MS in the United States to create a large, deidentified, longitudinal data set for clinical research. PicnicHealth obtains health records, including paper charts, electronic health records, and radiology imaging files from any healthcare site. Using a large-scale health record processing pipeline, PicnicHealth abstracts standard and condition-specific data elements from structured (eg, laboratory test results) and unstructured (eg, narrative) text and maps these to standardized medical vocabularies. Researchers can use the resulting data set to answer empirical questions and study participants can access and share their harmonized health records using PicnicHealth's web application. RESULTS: As of November 24, 2020, more than 4176 participants from 49 of 50 US states have enrolled in the FlywheelMS study. A median of 200 pages of records have been collected from 14 different doctors over 8 years per participant. Abstraction precision, established through inter-abstractor agreement, is as high as 97.8% when identifying and mapping data elements to a standard ontology. CONCLUSION: Using a commercial health records platform, the FlywheelMS study is generating a real-world, multimodal data set that could provide valuable insights about patients with MS. This approach to data collection and abstraction is disease-agnostic and could be used to address other clinical research questions in the future.

Onset of depressive symptoms among adults with asthma: results from a longitudinal observational cohort.

AIMS: Individuals with asthma may be at increased risk of depression, but few studies have identified precursors to the onset of depression. The study goal was to identify risk factors for depression onset among a community-based sample of adults with asthma. METHODS: Data were obtained from three telephone interviews conducted at 2-yearly intervals on a longitudinal cohort of adults with asthma (n=439). The Center for Epidemiologic Studies Depression scale (CESD) was used to measure depressive symptoms. Multiple regression analyses tested associations of sociodemographic and health-related variables with depression prevalence (cross-sectional analyses) and incident depression (longitudinal analyses). RESULTS: 15% of subjects were classified as "depressed" (CESD> or =23) at each interview. Individuals depressed at baseline were more likely to drop out (OR=1.76 [95% CI 1.05, 2.96]). Low perceived control of asthma (measured with the Perceived Control of Asthma Questionnaire [PCAQ]) exhibited the most consistent association with depression. Lower PCAQ was cross-sectionally associated with depression (OR=0.51 per 0.5 SD difference in PCAQ [0.35, 0.75]). Onset of depression was noted in 38 individuals. Decrease in perceived control at follow-up was associated with depression onset (OR=7.47 [2.15, 26.01]). CONCLUSIONS: Low perceived control of asthma predicted depression onset among adults with asthma. This risk factor may respond to self-management education.

Exploring the Impact of Fatigue in Progressive Multiple Sclerosis: A Mixed-Methods Analysis.

BACKGROUND: Patient-focused literature on fatigue in progressive forms of multiple sclerosis (MS) is sparse. This study aimed to explore progressive MS patients' experiences of fatigue. METHODS: Adult patients in the United States with primary progressive MS (n=21) and secondary progressive MS (n=23), recruited from research panels, completed the following PRO measures: Patient Global Impression of Severity (Fatigue) (PGI-F); Fatigue Scale of Motor and Cognitive Functions (FSMC); Modified Fatigue Impact Scale (MFIS); Patient Health Questionnaire, two-item version (PHQ-2); and Patient Determined Disease Steps (PDDS). Patients subsequently participated in a 45-minute semistructured telephone interview and were asked to describe their MS symptoms and to comment on how MS affected their day-to-day lives. More detailed questions followed on the nature of their fatigue, including symptoms, impacts, frequency, and bothersomeness. RESULTS: Patients' mean age was 52.5 years, mean time since diagnosis was 14.7 years, and 81.8% were female. 79.5% of patients were unemployed and/or receiving disability benefits. Of all spontaneously reported MS symptoms, fatigue was the most common (n=38, 86.4%), followed by ambulation problems (n=31, 70.5%) and muscle weakness (n=25, 56.8%). Patients used the words "tired," "exhausted," "wiped out," and having "little or no energy" to describe their fatigue. More patients rated fatigue as their "most troubling symptom" (n=17, 38.6%) compared with other MS-related symptoms. Half of patients reported feeling constantly fatigued, and more than 90% reported experiencing fatigue at least daily. The top three most frequently reported negative impacts of fatigue were social functioning, emotional well-being, and cognitive functioning (all >80%). Patients described themselves as "homebodies," as fatigue limited their social interactions with friends and family and impacted the types of activities they could participate in. Patients attributed their inability to think clearly or focus for long periods of time to their fatigue. Patients also reported experiencing depression and anxiety because of their fatigue, which would often have further negative effects on their relationships with friends and family. On the fatigue PRO measures, mean (standard deviation) scores were 75.2 (14.7) on the FSMC and 55.0 (15.2) on the MFIS. Most participants scored in the "high" fatigue category on the FSMC (84.1%) and above the clinically significant fatigue threshold (86.4%). MFIS and FSMC total scores correlated with PGI-F (polyserial correlations r=0.74 and r=0.62, both p<0.01) and PHQ-2 (r=0.56 and r=0.57, both p<0.01), but not with PDDS (r=0.09 and r=0.02, both p>0.05). CONCLUSIONS: Fatigue is a common, troublesome, and disabling symptom which has a profound impact on patients' daily lives, as evidenced by qualitative analyses and high scores on established fatigue measures observed in this sample. These findings provide insights into the burden of fatigue and can inform its measurement in both clinical and research settings. Treatments that improve the symptoms of fatigue or prevent exacerbations are needed for patients with progressive MS.

Screening for depression in chronic obstructive pulmonary disease.

Depression and chronic obstructive pulmonary disease (COPD) are major causes of disability. Identifying COPD patients at risk for depression would facilitate the alleviation of an important comorbidity conferring additional risk for poor outcomes. The purpose of this study was to determine the utility of a brief screening measure, the 15-item Geriatric Depression Scale (GDS-15), in detecting the mood disorders in persons with COPD. This is a cross-sectional study of 188 persons with COPD, stratified by age (65 and older versus less than 65) and COPD severity using Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging. Screening cut-points were empirically derived using threshold selection methods and receiver operating characteristic (ROC) curves were estimated. The GDS-15 was used as a screening measure and diagnoses of Major Depressive Disorder (MDD) or other mood disorders were determined using a "gold standard" standardized structured clinical interview. Of the 188 persons with COPD, 25% met criteria for any mood disorder and 11% met criteria for MDD. Optimal threshold estimations suggested a GDS cut score of 5, which yielded adequate sensitivity and specificity in detecting MDD (81% and 87%, respectively) and correctly classified 86% of participants. To detect the presence of any mood disorder, a cut score of 4 was suggested yielding sensitivity and specificity of 67% and 82%, respectively; correctly classifying 79%. These results suggest that mood disorders are relatively common among persons with COPD. The GDS-15 is a useful screening measure to identify patients at risk for depression.

Ocrelizumab infusion experience in patients with relapsing and primary progressive multiple sclerosis: Results from the phase 3 randomized OPERA I, OPERA II, and ORATORIO studies.

BACKGROUND: Ocrelizumab is an infusible humanized monoclonal antibody that selectively depletes CD20+ B cells. Infusion-related reactions (IRRs) were summarized from the OPERA I, OPERA II, and ORATORIO trials for relapsing and primary progressive multiple sclerosis (MS). METHODS: OPERA I and OPERA II were identical, randomized, double-blind, active-controlled trials that enrolled patients with relapsing MS (RMS). Patients in the ocrelizumab group initially received two 300-mg intravenous (IV) infusions separated by 14 days (on Days 1 and 15); subsequent doses were administered as single 600-mg IV infusions. Ocrelizumab-treated patients also received subcutaneous (SC) placebo injections 3 times weekly. Patients in the active comparator group received SC injections of IFN ß-1a 3 times weekly, as well as placebo infusions on Days 1 and 15 and Weeks 24, 48, and 72. ORATORIO was a randomized, parallel-group, double-blind, placebo-controlled study that enrolled patients with primary progressive MS (PPMS). As in the OPERA studies, patients in the ocrelizumab group initially received two 300-mg infusions separated by 14 days; however, ORATORIO patients continued to receive this divided-dose regimen throughout the study. The ORATORIO control group received IV placebo. Prior to each infusion, all patients in the OPERA and ORATORIO studies were pretreated with 100 mg IV methylprednisolone; additional prophylactic treatment with analgesics, antipyretics, and/or an IV or oral antihistamine was optional. IRRs were defined as adverse events that occurred during or within 24 h of IV infusion of ocrelizumab or placebo. RESULTS: Safety analyses included 1651 patients with RMS from OPERA I and OPERA II (ocrelizumab, n = 825; IFN ß-1a, n = 826) and 725 patients with PPMS from ORATORIO (ocrelizumab, n = 486; placebo, n = 239). Across studies, IRRs were reported in 34.3% (vs 9.7% with IFN ß-1a) and 39.9% (vs 25.5% with placebo) of ocrelizumab-treated patients in the pooled OPERA and ORATORIO populations, respectively. The majority of IRRs were mild to moderate in the OPERA (ocrelizumab, 92.6%; IFN ß-1a, 98.8%) and ORATORIO (ocrelizumab, 96.9%; placebo, 93.4%) studies. IRRs most commonly occurred with the first infusion. Severe IRRs were reported in 2.4% of ocrelizumab-treated patients in the OPERA studies (vs 0.1% with IFN ß-1a) and 1.2% of ocrelizumab-treated patients in ORATORIO (vs 1.7% with placebo). Two serious IRRs occurred across the OPERA studies, both of which occurred with the initial infusion. The first event occurred in an IFN ß-1a-treated patient in association with the initial infusion of IV placebo and consisted of severe balance disorder, dizziness, flushing, and hypoesthesia. The second event was a life-threatening reaction (bronchospasm) that occurred in an ocrelizumab-treated patient 15 min after the infusion started. Frequently reported IRR symptoms included pruritus, rash, throat irritation, and flushing. Premedication use, particularly antihistamines, was associated with fewer IRRs. CONCLUSION: Findings from the OPERA I, OPERA II, and ORATORIO trials show that IRRs were the most frequently reported adverse events with ocrelizumab, were mostly mild to moderate in severity, were reduced with appropriate pretreatment, and decreased with subsequent dosing. IRRs that did occur were effectively managed through infusion rate adjustment and symptomatic treatment.

Onset of clinical and MRI efficacy of ocrelizumab in relapsing multiple sclerosis.

OBJECTIVE: To assess the onset of ocrelizumab efficacy on brain MRI measures of disease activity in the phase II study in relapsing-remitting multiple sclerosis (RRMS), and relapse rate in the pooled phase III studies in relapsing multiple sclerosis (RMS). METHODS: Brain MRI activity was determined in the phase II trial at monthly intervals in patients with RRMS receiving placebo, ocrelizumab (600 mg), or intramuscular interferon (IFN) ß-1a (30 µg). Annualized relapse rate (ARR; over various epochs) and time to first relapse were analyzed in the pooled population of the phase III OPERA (A Study of Ocrelizumab in Comparison With Interferon Beta-1a [Rebif] in Participants With Relapsing Multiple Sclerosis) I and OPERA II trials in patients with RMS receiving ocrelizumab (600 mg) or subcutaneous IFN-ß-1a (44 µg). RESULTS: In patients with RRMS, ocrelizumab reduced the number of new T1 gadolinium-enhancing lesions by week 4 vs placebo (p = 0.042) and by week 8 vs intramuscular IFN-ß-1a (p < 0.001). Ocrelizumab also reduced the number of new or enlarging T2 lesions appearing between weeks 4 and 8 vs both placebo and IFN-ß-1a (both p < 0.001). In patients with RMS, ocrelizumab significantly reduced ARR (p = 0.005) and the probability of time to first protocol-defined relapse (p = 0.014) vs subcutaneous IFN-ß-1a within the first 8 weeks. CONCLUSION: Epoch analysis of MRI-measured lesion activity in the phase II study and relapse rate in the phase III studies consistently revealed a rapid suppression of acute MRI and clinical disease activity following treatment initiation with ocrelizumab in patients with RRMS and RMS, respectively. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that for patients with RRMS and RMS, ocrelizumab suppressed MRI activity within 4 weeks and clinical disease activity within 8 weeks.

Employment in multiple sclerosis. Exiting and re-entering the work force.

Multiple sclerosis (MS) is associated with significant economic burden and high rates of unemployment. This investigation evaluated patient and disease characteristics associated with work loss and work initiation using the NARCOMS patient registry. Patient and disease characteristics associated with transitions to unemployment or employment were evaluated cross-sectionally and prospectively over the course of two assessment periods (mean interval of 1.56 +/- 0.93 years). Eligible participants included 8,867 patients for the cross-sectional component, and 8,122 for longitudinal analyses. At Time 1 and Time 2 56-58 % of MS patients were not employed. At Time 1, unemployed participants more likely to have a progressive disease course, had a longer symptom duration, greater levels of disability as measured by the PDDS, and greater functional limitations across all domains of the performance scales (p < 0.0001 for all). At Time 2, increasing MS symptoms in the past 6 months increased the odds of becoming unemployed. In addition, specific problems in mobility, hand function, fatigue, and cognitive performance domains were associated with increased odds of becoming unemployed. Less severe problems in similar areas, including mobility, hand function, and cognitive functioning were also predictive of work initiation among patients not employed. MS is associated with high rates of unemployment. Specific physical and mental health limitations confer risk of employment cessation over time, as well as the likelihood of employment initiation. This study has implications for rehabilitation interventions to target specific MS related limitations that place patients at greatest risk for work status changes.

No evidence of disease activity (NEDA) analysis by epochs in patients with relapsing multiple sclerosis treated with ocrelizumab vs interferon beta-1a.

BACKGROUND: No evidence of disease activity (NEDA; defined as no 12-week confirmed disability progression, no protocol-defined relapses, no new/enlarging T2 lesions and no T1 gadolinium-enhancing lesions) using a fixed-study entry baseline is commonly used as a treatment outcome in multiple sclerosis (MS). OBJECTIVE: The objective of this paper is to assess the effect of ocrelizumab on NEDA using re-baselining analysis, and the predictive value of NEDA status. METHODS: NEDA was assessed in a modified intent-to-treat population (n = 1520) from the pooled OPERA I and OPERA II studies over various epochs in patients with relapsing MS receiving ocrelizumab (600 mg) or interferon beta-1a (IFN ß-1a; 44 µg). RESULTS: NEDA was increased with ocrelizumab vs IFN ß-1a over 96 weeks by 75% (p < 0.001), from Week 0‒24 by 33% (p < 0.001) and from Week 24‒96 by 72% (p < 0.001). Among patients with disease activity during Weeks 0‒24, 66.4% vs 24.3% achieved NEDA during Weeks 24‒96 in the ocrelizumab and IFN ß-1a groups (relative increase: 177%; p < 0.001). CONCLUSION: Superior efficacy with ocrelizumab compared with IFN ß-1a was consistently seen in maintaining NEDA status in all epochs evaluated. By contrast with IFN ß-1a, the majority of patients with disease activity early in the study subsequently attained NEDA status with ocrelizumab.

Examining the reliability and validity of the Clinical Assessment Interview for Negative Symptoms within the Management of Schizophrenia in Clinical Practice (MOSAIC) multisite national study.

The current study sought to expand on prior reports of the validity and reliability of the CAINS (CAINS) by examining its performance across diverse non-academic clinical settings as employed by raters not affiliated with the scale's developers and across a longer test-retest follow-up period. The properties of the CAINS were examined within the Management of Schizophrenia in Clinical Practice (MOSAIC) schizophrenia registry. A total of 501 participants with a schizophrenia spectrum diagnosis who were receiving usual care were recruited across 15 national Patient Assessment Centers and evaluated with the CAINS, other negative symptom measures, and assessments of functioning, quality of life and cognition. Temporal stability of negative symptoms was assessed across a 3-month follow-up. Results replicated the two-factor structure of the CAINS reflecting Motivation and Pleasure and expression symptoms. The CAINS scales exhibited high internal consistency and temporal stability. Convergent validity was supported by significant correlations between the CAINS subscales with other negative symptom measures. Additionally, the CAINS was significantly correlated with functioning and quality of life. Discriminant validity was demonstrated by small to moderate associations between the CAINS and positive symptoms, depression, and cognition (and these associations were comparable to those found with other negative symptom scales). Findings suggest that the CAINS is a reliable and valid tool for measuring negative symptoms in schizophrenia across diverse clinical samples and settings.

Telephone-administered psychotherapy for depression.

BACKGROUND: Several studies have shown that telephone-administered cognitive-behavioral therapy (T-CBT) is superior to forms of no treatment controls. No study has examined if the skills-training component to T-CBT provides any benefit beyond that provided by nonspecific factors. OBJECTIVE: To test the efficacy of a 16-week T-CBT against a strong control for attention and nonspecific therapy effects. DESIGN: Randomized controlled trial including 12-month follow-up. SETTING: Telephone administration of psychotherapy with patients in their homes. PARTICIPANTS: Participants had depression and functional impairments due to multiple sclerosis. INTERVENTIONS: A 16-week T-CBT program was compared with 16 weeks of telephone-administered supportive emotion-focused therapy. MAIN OUTCOME MEASURES: Hamilton Depression Rating Scale score, Structured Clinical Interview for DSM-IV diagnosis of major depressive disorder, Beck Depression Inventory score, and Positive Affect scale score of the Positive and Negative Affect Scale. RESULTS: Of the 127 participants randomized, 7 (5.5%) dropped out of treatment. There were significant improvement during treatment on all outcome measures (P<.01 for all) and an increase in Positive Affect Scale score. Improvements over 16 weeks of treatment were significantly greater for T-CBT, compared with telephone-administered supportive emotion-focused therapy, for major depressive disorder frequency (P = .02), Hamilton Depression Rating Scale score (P = .02), and Positive Affect Scale score (P = .008), but not for the Beck Depression Inventory score (P = .29). Treatment gains were maintained during 12-month follow-up; however, differences across treatments were no longer evident (P > .16 for all). CONCLUSIONS: Patients showed significant improvements in depression and positive affect during the 16 weeks of telephone-administered treatment. The specific cognitive-behavioral components of T-CBT produced improvements above and beyond the nonspecific effects of telephone-administered supportive emotion-focused therapy on evaluator-rated measures of depression and self-reported positive affect. Attrition was low.

Longitudinal associations between MRI and cognitive changes in very early MS.

OBJECTIVES: Cognitive dysfunction in multiple sclerosis (MS) has been primarily examined in patients with advanced disease. Our objective was to study the longitudinal associations between brain magnetic resonance imaging (MRI) metrics and neuropsychological outcomes in patients with early MS. METHODS: Relapsing MS patients within 12 months of onset were enrolled in a neuroprotection trial of riluzole versus placebo with up to 36 months of follow-up. MRI metrics included percent brain volume changes measured by SIENAX normalized measurements [normalized brain parenchymal volume (nBPV), normalized normal-appearing white and gray matter volume (nNAWMV and nGMV)] and T2 lesion volume (T2LV). A neuropsychological battery was performed annually. Mixed model regression measured time trends and associations between imaging and neuropsychological outcomes, adjusting for sex, age and education level. RESULTS: Forty-three patients (mean age 36 years; 31 females) were enrolled within 7.5 ± 4.9 months of disease onset. 11.6% of patients with baseline cognitive assessment met conservative criteria for cognitive impairment. Compared to placebo, riluzole had no significant effect on neuropsychological performance; thus, both groups were combined for the association analyses. Baseline T2LV predicted subsequent changes in PASAT (p=0.006) and SDMT (p=0.002) scores. Longitudinal changes of T2LV were associated with changes in CVLT-II (p<0.001). CONCLUSION: These findings suggest that cognitive impairment is relatively common in patients with very early MS. Baseline and longitudinal changes in the lesion load may be associated with some of the most frequently identified changes in cognitive function in MS.

The Management of Schizophrenia in Clinical Practice (MOSAIC) Registry: a focus on patients, caregivers, illness severity, functional status, disease burden and healthcare utilization.

BACKGROUND: The Management of Schizophrenia in Clinical Practice (MOSAIC), a disease-based registry of schizophrenia, was initiated in December 2012 to address important gaps in our understanding of the impact and burden of schizophrenia and to provide insight into the current status of schizophrenia care in the US. Recruitment began in December 2012 with ongoing assessment continuing through May 2014. METHODS: Participants were recruited from a network of 15 centralized Patient Assessment Centers supporting proximal care sites. Broad entry criteria included patients diagnosed with schizophrenia, schizophreniform or schizoaffective disorder, presenting within the normal course of care, in usual treatment settings, aged ≥18years and able to read and speak English. RESULTS: By May 2014, 550 participants (65.8% male, 59.8% White, 64.4% single, mean age 42.9years), were enrolled. The majority had a diagnosis of schizophrenia (62.0%). Mean illness duration at entry was 15.0years. Common comorbidities at entry were high lipid levels (26.9%), hypertension (23.1%) and type II diabetes (13%). Participants were categorized by baseline overall Clinical Global Impression-Schizophrenia Severity Score as minimally (9.1%), mildly (25.3%), moderately (39.9%), markedly (22.3%) and severely (3.4%) ill. Most commonly used second generation antipsychotics at entry were risperidone (17.8%), clozapine (16.5%), olanzapine (14.0%), aripiprazole (13.6%) and quetiapine (5.6%). CONCLUSIONS: No large-scale patient registry has been conducted in the US to longitudinally follow patients with schizophrenia and describe symptom attributes, support network, care access and disease burden. These data provide important epidemiological, clinical and outcome insights into the burden of schizophrenia in the US.

Treatment adherence and transitioning youth in pediatric multiple sclerosis.

BACKGROUND: Transitioning youth with multiple sclerosis (MS) represent a vulnerable group to potentially poor outcomes. It is unknown how pediatric MS patients transition into adult care. OBJECTIVES: To describe self-management skills that include adherence to disease-modifying therapies, quality of life measures, illness perception, transition readiness and healthcare skills assessments in patients with pediatric MS and associations with clinical and cognitive outcomes. METHODS: This is a prospective cross-sectional study at the pediatric MS center and transitional MS clinic at the University of California, San Francisco. Patients and one of their parents completed validated surveys for self-management skills. Non-adherence is defined as not taking their medication more than 20% of the time in the past 1 month. Wilcoxin matched-pairs rank test and McNemar's tests were used for comparison of patient and parent responses. Univariate and multivariate regression models were used for analyses adjusting for disease duration and socio-economic status. RESULTS: Thirty patients were enrolled with a mean (+/-SD) age of 15.8 years+/-2.8, 53% was female and 47% Hispanic. The rate of non-adherence was 37%. The most common reason for non-adherence was forgetting to take their medication reported in 50% of patients. In adjusted regression models, higher EDSS was associated with a lower score on patient's quality of life (13 points decrease, 95% CI 6­18, p<0.0001), and lower healthcare skills (15 points decrease, 95% CI5­26, p=0.006). Four points increase in Symbol Digit Modalities Test score was associated a 0.1 increase in transition readiness score (95% CI0.07­0.2, p=0.001) and 3.9 points increase in health care skills scores (95% CI 1.7­6, p=0.008).

A randomized controlled phase II trial of riluzole in early multiple sclerosis.

OBJECTIVES: We evaluated the effect of riluzole versus placebo added to weekly IM interferon beta-1a in early multiple sclerosis (MS). METHODS: This is a randomized (1:1), double-blind, placebo-controlled trial of riluzole 50 mg twice daily in subjects with MS onset less than 1 year prior. Trial participation was up to 3 years. The primary endpoint was change in percent brain volume change. Secondary endpoints included changes in normalized gray and normal-appearing white matter volumes, retinal nerve fiber layer thickness (RNFL), MS Functional Composite and Symbol Digit Modalities Test scores. Mixed model regression analysis was used to compare the changes over time between groups. RESULTS: Forty-three subjects were randomized to study drug (22 riluzole, 21 placebo). Baseline characteristics were overall similar between groups except for older age (P = 0.042), higher normalized cerebrospinal fluid volume (P = 0.050), lower normalized gray matter volume (P = 0.14), and thinner RNFL (P = 0.043) in the riluzole group. In the primary analysis, percent brain volume change in the placebo group decreased at a rate of 0.49% per year whereas the riluzole group decreased by 0.86% per year (0.37% more per year; 95% CI -0.78, 0.024; P = 0.065). Although age did not influence the rate of brain volume decline, the difference between groups was attenuated after adjustment for baseline normalized gray matter and lesion volume (0.26% more per year in riluzole group; 95% CI -0.057, 0.014; P = 0.22). Analyses of secondary outcomes showed no differences between groups. INTERPRETATION: This trial provides class 1 evidence that riluzole treatment does not meaningfully reduce brain atrophy progression in early MS.
