Abstract
Aim: To assess time to improvement in Quality of Life in Neurological Disorders (Neuro-QoL) domains for patients treated with natalizumab versus ocrelizumab. Methods: Patients enrolled in the MS PATHS network who initiated treatment with either natalizumab or ocrelizumab rated the Neuro-QoL domains of physical function, symptoms, emotional health, cognitive function and social ability. Results: Time to clinically meaningful improvement was significantly shorter with natalizumab versus ocrelizumab for cognitive function (event time ratio [95% CI]: 0.37 [0.24-0.57]; p < 0.001), sleep disturbance (0.45 [0.28-0.72]; p = 0.001), social role participation (0.37 [0.21-0.66]; p = 0.001) and social role satisfaction (0.5 [0.31-0.8]; p = 0.004). Conclusion: Natalizumab had shorter time to clinically meaningful improvement in cognitive, sleep, and social role Neuro-QoL domains versus ocrelizumab.

Abstract
Background Many individuals with multiple sclerosis (MS) depart the workforce prematurely. In the United States, access to insurance, including health, disability income, long-term care, and life insurance, is largely employment-based or purchased from earnings. Many individuals we see in the clinic experience financial hardship because of a lack of insurance, even if working. We sought to determine the proportion of workers who are financially protected through insurance coverage and the sources of this coverage in a large sample. Methods We developed an online survey and opened it to individuals aged 18 to 65 years registered with the North American Research Committee on Multiple Sclerosis, iConquerMS, or the National Multiple Sclerosis Society Minority Advisory Council. Data collected included demographic and disease characteristics, current information about each insurance type (coverage vs no coverage), and when the current insurance policies were obtained relative to MS diagnosis. Results Of 2507 survey respondents, 82.9% were female, 3.8% Hispanic/Latino, and 91.2% White. The mean ± SD age was 53.5 ± 8.5 years and disease duration was 16.4 ± 8.5 years after diagnosis. The most frequently held insurance types were health (96.3%) and life (58.8%). Only 9.7% of respondents had long-term care insurance. Except for life insurance, most current policies were obtained after MS diagnosis. Conclusions Individuals with MS might not prioritize the possible short- and long-term benefits of these types of insurance. Health care providers can direct patients to nonprofit agencies that educate about of these insurance types and emphasize that others with MS have obtained these insurance types after their diagnosis.

Abstract
BACKGROUND There are no validated clinical outcome assessments (COAs) used in neurosarcoidosis. OBJECTIVE We surveyed clinicians who treat patients with neurosarcoidosis to determine: 1) current approaches to assessment of neurologic impairment, and 2) clinicians' needs regarding future COA development. METHODS Physician contacts from the Foundation for Sarcoidosis Research and Neurosarcoidosis Consortium Group were sent an online survey. RESULTS For 43/143 responders, COAs were used in a minority of settings. Apart from time for administration, the biggest barriers to implementation were lack of validated, disease-specific measures. CONCLUSIONS Lack of validated, disease-specific measures is a barrier to monitoring neurological impairment in neurosarcoidosis.

Abstract
Dendritic spines are specialized sites of synaptic innervation modulated by activity and serve as substrates for learning and memory. Recently, dendritic spines have been described for DD GABAergic neurons as the input sites from presynaptic cholinergic neurons in the motor circuit of Caenorhabditis elegans. This synaptic circuit can now serve as a powerful new in vivo model of spine morphogenesis and function that exploits the facile genetics and ready accessibility of C. elegans to live-cell imaging. This protocol describes experimental strategies for assessing DD spine structure and function. In this approach, a super-resolution imaging strategy is used to visualize the intricate shapes of actin-rich dendritic spines. To evaluate the DD spine function, the light-activated opsin, Chrimson, stimulates the presynaptic cholinergic neurons, and the calcium indicator, GCaMP, reports the evoked calcium transients in postsynaptic DD spines. Together, these methods comprise powerful approaches for identifying genetic determinants of dendritic spines in C. elegans that could also direct spine morphogenesis and function in the brain.

Abstract
Background Optimizing multiple sclerosis treatment warrants understanding of changes in physical, mental, and social health. Objective To assess the impact of natalizumab on Quality of Life in Neurological Disorders (Neuro-QoL) scores. Methods Annualized change in T-scores and likelihood of ≥5-point improvement over baseline were calculated for each Neuro-QoL domain after natalizumab initiation. Comparisons with ocrelizumab-treated patients were conducted after propensity score weighting and adjustment for relevant co-medications, year, and drug-year interaction. Results Among 164 natalizumab patients analyzed, 8 of 12 Neuro-QoL domains improved significantly, with greater improvement in patients with abnormal baseline Neuro-QoL. In the subgroup comparison of natalizumab-treated (n = 145) and ocrelizumab-treated (n = 520) patients, significant improvement occurred in 9 of 12 and 4 of 12 domains, respectively. The difference between groups was statistically significant for positive affect and well-being (p = 0.02), sleep (p = 0.003), and satisfaction with social roles and activities (SRA) (p = 0.03) in the overall population and for emotional and behavioral dyscontrol (p = 0.01), participation in SRA (p = 0.0001), and satisfaction with SRA (p = 0.02) in patients with abnormal baseline Neuro-QoL. Conclusions Natalizumab can produce clinically meaningful improvements in mental and social health. Such improvements are unlikely to be primarily driven by expectation bias, as their magnitude exceeded improvements with another high-efficacy therapy, ocrelizumab.

Abstract
This study investigated the efficacy of using Vikane gas fumigant (sulfuryl fluoride) at the 1.9× dosage rate for eliminating bed bugs (Cimex lectularius L.) in two challenging infestation situations: personal vehicles, and confined spaces densely packed with personal belongings. The vehicles used in this study were large minivans with seating that folded into the floor. The confined spaces were cargo trailers filled to 85% capacity with books, furniture, and other household items. Each van and trailer was equipped with ~90 sentinel bed bugs consisting of three groups of 9-11 bed bug eggs, 10 nymphs, and 10 adults. The Vikane Fumiguide calculator was used to determine the target dosage (g-h/m3) to apply in each replicate (e.g., one van or trailer). Sulfuryl fluoride concentrations were measured throughout the fumigation process using a Spectros SF-ReportIR. Concentration readings were input into the Fumiguide to determine when the accumulated dosage (g-h/m3) was achieved, and when aeration should be initiated. After aeration was complete, the sentinel bed bugs were removed from the replicates and bed bug nymph and adult mortality was recorded. Bed bug eggs were monitored for 23 d to determine latent mortality. Fumigated bed bug mortality for each replication was 100% regardless of life stage. Latent mortality was observed in a single bed bug egg, but the first instar never fully eclosed. This study determined that fumigation with sulfuryl fluoride at the 1.9× dosage factor is an effective method for eliminating resistant bed bugs from vehicles and personal belongings in densely packed situations.

Abstract
Background: In order to provide patient center care, our multiple sclerosis (MS) clinic assesses patient concerns before clinical encounters, first by asking the optional qualitative question “What is the most important thing you what your health-care provider to know today” (most important concern of the patient [MIPC]) and then completing quantitative patient-reported outcome measures (PROMs) including Quality of Life in Neurological Disorders (Neuro-QoL). Both sets of questions are designed to facilitate encounters that address patients’ values and preferences. Objective: Determine whether the qualitative MIPC responses provided unique information not included in PROMs or clinical assessments. Methods: We randomly selected 400 first-time MIPC responders and 400 first-time MIPC nonresponders from 2788 participants in our database. We categorized MIPC responses by content and number of unique concerns and appended them to the Neuro-QoL framework. Nonresponders were compared to those who provided 1 and 2 or more responses. Results: Several MIPCs MS symptoms categories were added to the Neuro-QoL Physical domain. Most important concern of the patients work and cost-of-care categories were added to the Social Domain. Domains regarding treatment satisfaction and disease management were added. Two hundred thirty (58%) MIPC respondents reported 1 concern, 140 (35%) expressed 2 to 6 concerns, and 30 (7%) reported MS-unrelated concerns and not analyzed. Physical symptoms were the most common MIPC (69.9%). Respondents with more concerns were more likely African American, lacked private insurance, and worse disability. Conclusions: Importantly, MIPC responders described idiosyncratic symptoms, disease management, and social concerns not included in the PROMS, suggesting the MIPC question offered patients a unique opportunity to share specific concerns with their providers.

Abstract
INTRODUCTION The Neuro-QoL is a standardized approach to assessing health-related quality of life in people with neurological conditions, including multiple sclerosis (MS). Item banks were developed with item response theory (IRT) methodology so items are calibrated along a continuum of each construct. The purpose of this study was to develop a preference-based scoring algorithm for the Neuro-QoL to derive utilities that could be used in economic modeling. METHODS With input from neurologists, 6 Neuro-QoL domains were selected based on relevance to MS and used to define health states for a utility elicitation study in the United Kingdom. General population participants and individuals with MS valued the health states and completed questionnaires (including Neuro-QoL short forms). The Neuro-QoL Utility Scoring System (NQU) was derived based on multi-attribute utility theory using data from the general population sample. Single-attribute disutility functions for 6 Neuro-QoL domains were estimated using isotonic regression with linear interpolation and then combined with a multiplicative model. NQU validity was assessed using MS participant data. RESULTS Interviews were completed with 203 general population participants (50.2% female; mean age = 45.0 years) and 62 participants with MS (62.9% female; mean age = 46.1 years). Mean (SD) NQU scores were 0.94 (0.06) and 0.82 (0.13) for the general population and MS samples, respectively. The NQU demonstrated known-groups validity by differentiating among subgroups categorized based on level of disability. The NQU demonstrated convergent validity via correlations with generic measures (0.66 and 0.63 with EQ-5D-5L and Health Utilities Index Mark 3, respectively; both P < 0.001). DISCUSSION With the NQU, utilities can be derived from any MS treatment group, subgroup, or patient sample who completes items from 6 Neuro-QoL domains. Because the Neuro-QoL is frequently used with MS patients, the NQU greatly expands the options for quantifying outcomes in cost-utility analyses conducted to inform allocation of resources for MS treatment.

Abstract
There is a growing need for patient and public involvement (PPI) to inform the way that research is developed and performed. International randomized controlled trials are particularly likely to benefit from PPI, but guidance is lacking on how or when it should be incorporated. In this article, we describe the PPI process that occurred during the design and initiation of an international treatment clinical trial in MS. PPI was incorporated using a structured approach, aiming to minimize bias and achieve equivalence in study design, implementation, and interpretation. Methods included PPI representation within the study research team, and the use of focus groups, analyzed using thematic framework analysis. We report the outcomes of PPI and make recommendations on its use in other neurology clinical trials. By sharing our model for PPI, we aim to maximize effectiveness of future public involvement and to allow its effect to be better evaluated.

Abstract
BACKGROUND Comprehensive and efficient assessments are necessary for clinical care and research in chronic diseases. Our objective was to assess the implementation of a technology-enabled tool in MS practice. METHOD We analyzed prospectively collected longitudinal data from routine multiple sclerosis (MS) visits between September 2015 and May 2018. The MS Performance Test, comprising patient-reported outcome measures (PROMs) and neuroperformance tests (NPTs) self-administered using a tablet, was integrated into routine care. Descriptive statistics, Spearman correlations, and linear mixed-effect models were used to examine the implementation process and relationship between patient characteristics and completion of assessments. RESULTS A total of 8022 follow-up visits from 4199 patients (median age 49.9 [40.2-58.8] years, 32.1% progressive course, and median disease duration 13.6 [5.9-22.3] years) were analyzed. By the end of integration, the tablet version of the Timed 25-Foot Walk was obtained in 89.0% of patients and the 9-Hole Peg Test in 94.8% compared with 74.2% and 64.3%, respectively before implementation. The greatest increase in data capture occurred in processing speed and low-contrast acuity assessments (0% prior vs 78.4% and 36.7%, respectively, following implementation). Four PROMs were administered in 41%-98% of patients compared with a single depression questionnaire with a previous capture rate of 70.6%. Completion rates and time required to complete each NPT improved with subsequent visits. Younger age and lower disability scores were associated with shorter completion time and higher completion rates. CONCLUSIONS Integration of technology-enabled data capture in routine clinical practice allows acquisition of comprehensive standardized data for use in patient care and clinical research.

Abstract
BACKGROUND AND PURPOSE To analyze the relationship between cognitive processing speed, patient-reported outcome measures (PROMs), employment and magnetic resonance imaging (MRI) metrics in a large multiple sclerosis cohort. METHODS Cross-sectional clinical data, PROMs, employment and MRI studies within 90 days of completion of the Processing Speed Test (PST), a technology-enabled adaptation of the Symbol Digit Modalities Test, were collected. MRI was analyzed using semi-automated methods. Correlations of PST score with PROMs and MRI metrics were examined using Spearman's rho. Wilcoxon rank sum testing compared MRI metrics across PST score quartiles and linear regression models identified predictors of PST performance. Effects of employment and depression were also investigated. RESULTS In 721 patients (mean age 47.6 ± 11.4 years), PST scores were significantly correlated with all MRI metrics, including cord atrophy and deep gray matter volumes. Linear regression demonstrated self-reported physical disability, cognitive function, fatigue and social domains (adjusted R2 = 0.44, P < 0.001) as the strongest clinical predictors of PST score, whereas that of MRI variables included T2 lesion volume, whole-brain fraction and cord atrophy (adjusted R2 = 0.42, P < 0.001). An inclusive model identified T2 lesion volume, whole-brain fraction, self-reported upper extremity function, cognition and social participation as the strongest predictors of PST score (adjusted R2 = 0.51, P < 0.001). There was significant effect modification by depression on the relationship between self-reported cognition and PST performance. Employment status was associated with PST scores independent of age and physical disability. CONCLUSION The PST score correlates with PROMs, MRI measures of focal and diffuse brain injury, and employment. The PST score is a feasible and meaningful measure for routine multiple sclerosis care.

Abstract
BACKGROUND AND PURPOSE The purpose was to determine the test-retest reliability, practice effects, convergent validity and sensitivity to multiple sclerosis (MS) disability of neuroperformance subtests from the patient self-administered Multiple Sclerosis Performance Test (MSPT) designed to assess low contrast vision (Contrast Sensitivity Test, CST), upper extremity motor function (Manual Dexterity Test, MDT) and lower extremity motor function (Walking Speed Test, WST) and to introduce the concept of regression-based norms to aid clinical interpretation of performance scores using the MSPT cognition test (Processing Speed Test, PST) as an example. METHODS Substudy 1 assessed test-retest reliability, practice effects and convergent validity of the CST, MDT and WST in 30 MS patients and 30 healthy controls. Substudy 2 examined sensitivity to MS disability in over 600 MS patients as part of their routine clinic assessment. Substudy 3 compared performance on the PST in research volunteers and clinical samples. RESULTS The CST, MDT and WST were shown to be reliable, valid and sensitive to MS outcomes. Performance was comparable to technician-administered testing. PST performance was poorer in the clinical sample compared with the research volunteer sample. CONCLUSIONS The self-administered MSPT neuroperformance modules produce reliable, objective metrics that can be used in clinical practice and support outcomes research. Published studies which require patient voluntary consent may underestimate the rate of cognitive dysfunction observed in a clinical setting.

Abstract
Introduction In the clinic, the assessment of patients with multiple sclerosis (MS) is typically qualitative and non-standardized. Objectives To describe the MS Performance Test (MSPT), an iPad Air® 2 (Apple, Cupertino, CA, USA)-based neurological assessment platform allowing patients to input relevant information without the aid of a medical technician, creating a longitudinal, clinically meaningful, digital medical record. To report results from human factor (HF) and usability studies, and the initial large-scale implementation in a practice setting. Methods The HF study examined use-error patterns in small groups of MS patients and healthy controls (n = 14), the usability study assessed the effectiveness of patient interaction with the tool by patients with a range of MS disability (n = 60) in a clinical setting, and the implementation study deployed the MSPT across a diverse population of patients (n = 1000) in a large MS center for routine clinical care. Results MSPT assessments were completed by all users in the HF study; minor changes to design were recommended. In the usability study, 73% of patients with MS completed the MSPT, with an average administration time of 32 min; 85% described their experience with the tool as satisfactory. In the initial implementation for routine care, 84% of patients with MS completed the MSPT, with an average administration time of 28 min. Conclusion Patients with MS with varying disability levels completed the MSPT with minimal or no supervision, resulting in comprehensive, efficient, standardized, quantitative, clinically meaningful data collection as part of routine medical care, thus allowing for large-scale, real-world evidence generation.

Abstract
Nitrogen runoff from pastures fertilized with animal manure, such as poultry litter, can result in accelerated eutrophication. The objective of this study was to evaluate the long-term effects of grazing management and buffer strips on N runoff from pastures fertilized with poultry litter. A 12-yr study was conducted on 15 small watersheds in Booneville, AR, using five management practices: continuous grazing, haying, rotational grazing, rotational grazing with an unfertilized buffer strip, and rotational grazing with a fenced unfertilized riparian buffer. Poultry litter was applied annually at a rate of 5.6 Mg ha. Concentrations and loads of total N, NO-N, NH-N, organic N, and total organic C in runoff varied intra- and interannually and coincided with precipitation trends. Overall, the greatest component of total N in runoff was organic N. Rotational grazing resulted in the highest concentrations and loads of all forms of N in runoff compared with other treatments, including the continuously grazed paddocks, which were grazed almost twice as much. Total organic C concentrations and loads in runoff were also higher from rotationally grazed watersheds than other treatments. Rotational grazing is considered a best management practice that typically reduces soil erosion; hence, the mechanism by which it caused higher N and C runoff is unclear. Nitrogen runoff losses from rotationally grazed pastures were reduced by 44% with unfertilized buffer strips, by 54% with fenced unfertilized riparian buffers, and by 52% by converting pastures to hayfields.

Abstract
Background . Missense variants in the ryanodine receptor 1 gene ( RYR1 ) are associated with malignant hyperthermia but only a minority of these have met the criteria for use in predictive DNA diagnosis. We examined the utility of a simplified method of segregation analysis and a functional assay for determining the pathogenicity of recurrent RYR1 variants associated with malignant hyperthermia. Methods . We identified previously uncharacterised RYR1 variants found in four or more malignant hyperthermia families and conducted simplified segregation analyses. An efficient cloning and mutagenesis strategy was used to express ryanodine receptor protein containing one of six RYR1 variants in HEK293 cells. Caffeine-induced calcium release, measured using a fluorescent calcium indicator, was compared in cells expressing each variant to that in cells expressing wild type ryanodine receptor protein. Results. We identified 43 malignant hyperthermia families carrying one of the six RYR1 variants. There was segregation of genotype with the malignant hyperthermia susceptibility phenotype in families carrying the p.E3104K and p.D3986E variants, but the number of informative meioses limited the statistical significance of the associations. HEK293 functional assays demonstrated an increased sensitivity of RyR1 channels containing the p.R2336H, p.R2355W, p.E3104K, p.G3990V and p.V4849I compared with wild type, but cells expressing p.D3986E had a similar caffeine sensitivity to cells expressing wild type RyR1. Conclusions . Segregation analysis is of limited value in assessing pathogenicity of RYR1 variants in malignant hyperthermia. Functional analyses in HEK293 cells provided evidence to support the use of p.R2336H, p.R2355W, p.E3104K, p.G3990V and p.V4849I for diagnostic purposes but not p.D3986E.

Abstract
Patient-reported outcomes (PROs) are playing an increasing role in multiple sclerosis (MS) research and practice, and are essential for understanding the effects that MS and MS treatments have on patients' lives. PROs are captured directly from patients and include symptoms, function, health status, and health-related quality of life. In this article, we review different categories (e.g., generic, targeted, preference-based) of PRO measures and considerations in selecting a measure. The PROs included in MS clinical research have evolved over time, as have the measures used to assess them. We describe findings from recent MS clinical trials that included PROs when evaluating Food and Drug Administration-approved disease-modifying therapies (e.g., daclizumab, teriflunomide). Variation in the measures used in these trials makes it difficult to draw any conclusions from the data. We therefore suggest a standardized approach to PRO assessment in MS research and describe 2 generic, National Institutes of Health-supported measurement systems [Neuro-QoL and the Patient-Reported Outcomes Measurement Information System (PROMIS)] that would facilitate such an approach. The use of PROs in MS care and research is expanding beyond clinical trials, as is demonstrated by examples from comparative effectiveness and other patient-centered research. The importance of PRO assessment is expected to continue to grow in the future.

Abstract
Background: The Multiple Sclerosis Outcome Assessments Consortium (MSOAC) was formed by
the National MS Society to develop improved measures of multiple sclerosis
(MS)-related disability. Objectives: (1) To assess the current literature and available data on functional
performance outcome measures (PerfOs) and (2) to determine suitability of
using PerfOs to quantify MS disability in MS clinical trials. Methods: (1) Identify disability dimensions common in MS; (2) conduct a comprehensive
literature review of measures for those dimensions; (3) develop an MS
Clinical Data Interchange Standards Consortium (CDISC) data standard; (4)
create a database of standardized, pooled clinical trial data; (5) analyze
the pooled data to assess psychometric properties of candidate measures; and
(6) work with regulatory agencies to use the measures as primary or
secondary outcomes in MS clinical trials. Conclusion: Considerable data exist supporting measures of the functional domains
ambulation, manual dexterity, vision, and cognition. A CDISC standard for MS
(http://www.cdisc.org/therapeutic#MS) was published, allowing
pooling of clinical trial data. MSOAC member organizations contributed
clinical data from 16 trials, including 14,370 subjects. Data from
placebo-arm subjects are available to qualified researchers. This
integrated, standardized dataset is being analyzed to support qualification
of disability endpoints by regulatory agencies.

Abstract
Background: Cognitive dysfunction is common in multiple sclerosis (MS) patients and has important consequences for daily activities, yet, unlike motor function, is not routinely assessed in the clinic setting. We developed the Processing Speed Test (PST), a self-administered iPad®-based tool to measure MS-related deficits in processing speed. Objective: To determine whether the PST is valid for screening cognitive dysfunction by comparing it to the paper-and-pencil Symbol Digit Modalities Test (SDMT). Methods: We assessed PST test–retest reliability, sensitivity of PST and SDMT in discriminating MS patients from healthy controls (HC), convergent validity between PST and SDMT, correlations between T2 lesion load and PST and SDMT, and PST performance with and without technician present during administration. Results: PST had excellent test–retest reliability, was highly correlated with SDMT, was slightly more sensitive than SDMT in discriminating MS from HC groups, and correlated better with cerebral T2 lesion load than did SDMT. Finally, PST performance was no different with or without a technician in the testing environment. Conclusion: PST has advantages over SDMT because of its efficient administration, scoring, and potential for medical record or research database integration. PST is a practical tool for routine screening of processing speed deficits in the MS clinic.

Abstract
Multiple sclerosis (MS) has important effects on quality of life but it is unknown how cognitive impairment affects the ability to assess or report this. O ur objective was to determine whether cognitive impairment negatively affects the construct validity and the reliability of the Multiple Sclerosis Q uality of Life Inventory (MSQLI). A neuropsychological test batter y and the Multiple Sclerosis Functional C omposite (MSFC) were administered to a sample of 136 patients referred for cognitive testing by their neurologists. A ge, sex, educatio n and ethnicity-adjusted T scores were calculated for each cognitive variable. C ognitive impairment was defined as any T score less than the fifth percentile. The MSQ LI was administered prior to neuropsychological testing and readministered one to four weeks later. C orrelations between the MSFC and the SF-36 were determined and compared between the cognitively impaired and unimpaired groups as the main test of construct validity. Test -retest and internal consistency reliability of each of the scales were compared for the impaired and unimpaired groups. Seventy-six (56%) patients were cognitively impaired. C onstruct validity and internal consistency reliability did not differ between the cognitively impaired and unimpaired groups. Test -retest reliability was lower for the bladder and vision scales in the impaired group, but remained acceptable for the bladder scale (r >0.7). C ognitive impairment, a common MS manifestation, does not appear to reduce the reliability or validity of the MSQ LI as a patient self-report measure of health status and quality of life.

Abstract
Cognitive impairment is common in multiple sclerosis (MS), but cannot be reliably predicted by physical impairment. The negative impact of cognitive impairment makes early detection important, but subjective cognitive complaints may be attributed to depression. We examined the relationship between subjectively reported and objectively measured cognitive impairment in MS, adjusting for mood. A neuropsychological battery, the Multiple Sclerosis Functional Composite (MSFC), the Mental Health Inventory (MHI), the Modified Fatigue Impact Scale (MFIS), the Perceived Deficits Questionnaire (PDQ) were administered to 136 patients. Demographically-adjusted cognitive scores were calculated. Subjective impairment was defined as PDQ score-2 standard deviations above that for healthy persons. We modeled the relationship of cognitive scores (independent variables) to being subjectively impaired (dependent variable) using logistic regression. Immediate Memory (IM) and Processing Speed Index (PSI) scores were non-linearly related to subjective impairment. Patients were less likely to report subjective impairment if their PSI was normal (OR-0.11; 0.02-0.73) or markedly impaired (OR-0.17; 0.03-0.91), compared to mildly reduced PSI. In young patients decreases in IM were associated with increased subjective impairment (OR-1.25; 1.07-1.47). Subjectively reported impairment reflects subtle declines in PSI and IM independent of mood, fatigue, and physical impairment. Cognitive complaints should not be discounted due to depression.

Abstract
Background The IMPACT study demonstrated the benefit of interferon beta-1a (IFNβ-1a, Avonex®) two-year change in disability measured by the Multiple Sclerosis Functional Composite (MSFC) in secondary progressive multiple sclerosis (SP-MS) and health-related quality of life (HRQoL) measured by the Multiple Sclerosis Quality of Life Inventory (MSQLI). The IMPACT data permit a detailed assessment of the relation between clinical and self-reported measures. Methods IMPACT was an international randomized, double-blind, placebo-controlled trial of SP-MS patients. As the MSQLI is only in English, this report includes US and Canadian subjects. Subjects were randomized to weekly intramuscular (im) injections of INb-1a (60 mg) or placebo for 24 months. Results At baseline and follow-up, MSQLI correlations were generally stronger with the EDSS than with the MSQLI, MSFC but comparable with MSFC components. Combining the two groups, MSQLI changes for those in the best and worst MSFC change quartiles demonstrated a statistical difference for six of the 11 MSQLI scales. Linear regression demonstrated that EDSS change from baseline to month-24 scores was correlated with change in two MSQLI components. Conclusion These data support the appropriateness of using the MSQLI with individuals who have SP-MS.

Abstract
Two methods were used to estimate the long-term impact of disease-modifying drug therapy (DMDT) in patients with relapsing multiple sclerosis (MS) who completed a placebo-controlled, randomized clinical trial of interferon beta-1a (IFNβ-1a). The study cohort consisted of patients with ambulatory relapsing MS who had previously participated in a placebo-controlled clinical trial for two years. At its end, patients were managed in an unstructured fashion by their neurologists and re-evaluated at an average of 6.1 years after the end of the trial. Follow-up evaluation was obtained for 93% of the 172 eligible patients. Because study inclusion criteria required that all patients have an Expanded Disability Status Scale (EDSS) score of ≤3.5 at entry, disability progression at follow-up was defined as EDSS≥6.0. Two methods were used to estimate the expected proportions that reached EDSS≥6.0 at follow-up. Estimates were compared with observed proportions. Method 1 used progression rates observed during the two-year phase III clinical trial and the percentage of time that patients were on DMDT during the follow-up period. Method 2 used progression rates from a natural history comparison group of relapsing-remitting MS patients. At the eight-year follow-up, 42.0% of the original placebo patients and 29.1% of the original IFNβ-1a patients reached an EDSS ≥ 6.0, an observed treatment effect of approximately 30%. Using method 1, it was estimated that 36.3% of the original placebo patients and 27.6% of the original IFNβ-1a patients should have reached an EDSS ≥ 6.0. Use of the natural history control group (method 2) predicted less plausible outcomes. Estimated proportions of patients reaching the endpoint were 63.3% for the original placebo group and 55.8% for the original IFNβ-1a group. Treatment effect sizes of 75-90% would be required to match estimates from method 2 with the observed outcome. The paucity of data on the long-term treatment of patients with MS may be aided by applying these or similar methods to vigorously followed cohorts of patients.

Abstract
Precision measurements of superallowed Fermi β-decay transitions, particularly for the lightest superallowed emitters ^{10}C and ^{14}O, set stringent limits on possible scalar current contributions to the weak interaction. In the present work, a discrepancy between recent measurements of the ^{10}C half-life is addressed through two high-precision half-life measurements, via γ-ray photopeak and β counting, that yield consistent results for the ^{10}C half-life of T_{1/2}=19.2969±0.0074 s and T_{1/2}=19.3009±0.0017 s, respectively. The latter is the most precise superallowed β-decay half-life measurement reported to date and the first to achieve a relative precision below 10^{-4}. A fit to the world superallowed β-decay data including the ^{10}C half-life measurements reported here yields b_{F}=-0.0018±0.0021 (68% C.L.) for the Fierz interference term and C_{S}/C_{V}=+0.0009±0.0011 for the ratio of the weak scalar to vector couplings assuming left-handed neutrinos.

Abstract
BACKGROUND Multiple sclerosis (MS) is a chronic, progressive, and disabling disease of the central nervous system with dramatic variations in the combination and severity of symptoms it can produce. The lack of reliable disease-specific health-related quality of life (HRQL) measures for use in clinical trials prompted the development of the Neurology Quality of Life (Neuro-QOL) instrument, which includes 13 scales that assess physical, emotional, cognitive, and social domains, for use in a variety of neurological illnesses. OBJECTIVE The objective of this research paper is to conduct an initial assessment of the reliability and validation of the Neuro-QOL short forms (SFs) in MS. METHODS We assessed reliability, concurrent validity, known groups validity, and responsiveness between cross-sectional and longitudinal data in 161 recruited MS patients. RESULTS Internal consistency was high for all measures (α = 0.81-0.95) and ICCs were within the acceptable range (0.76-0.91); concurrent and known groups validity were highest with the Global HRQL question. Longitudinal assessment was limited by the lack of disease progression in the group. CONCLUSIONS The Neuro-QOL SFs demonstrate good internal consistency, test-re-test reliability, and concurrent and known groups validity in this MS population, supporting the validity of Neuro-QOL in adults with MS.

Abstract
BACKGROUND Because multiple sclerosis (MS) is variable and unpredictable, if symptom worsening could be predicted, patients may feel better prepared to manage changes in function. OBJECTIVE The objective of this paper is to study the prediction of walking impairment in MS. METHODS We retrieved data for all MS patients at our center (2008-2009), including baseline and follow-up timed 25-foot walk (T25FW) times. We assessed the incidence of ≥20% worsening in T25FW by developing two survival models: (1) disease course and (2) Multiple Sclerosis Performance Scales (MSPS) score. The outcome was days until ≥20% worsening in T25FW. Covariates were disease subtype, years since diagnosis, Patient Health Questionnaire-9 (PHQ-9) score, and demographics. Data were interval censored; missing data were handled with multiple imputation. RESULTS Of 1544 patients, 309 (20%) experienced ≥20% worsening T25FW. For disease course, time to worsening was significantly shorter for secondary progressive vs. relapsing-remitting disease (p < 0.001). For MSPS, patients with lower baseline MSPS scores progressed more slowly (p = 0.001). In both models, sex, baseline T25W, and time since diagnosis were significantly associated with worsening. In the disease course model, PHQ 9 score may be related to worsening (p = 0.07). CONCLUSION These findings suggest factors associated with worsening in T25FW and a potential approach to establishing indicators associated with clinically significant change.

Abstract
Patient participation in cancer clinical trials is low. Little is known about attitudinal barriers to participation, particularly among patients who may be offered a trial during an imminent initial oncology consult. The aims of the present study were to confirm the presence of proposed subscales of a recently developed cancer clinical trial attitudinal barriers measure, describe the most common cancer clinical trials attitudinal barriers, and evaluate socio-demographic, medical and financial factors associated with attitudinal barriers. A total of 1256 patients completed a survey assessing demographic factors, perceived financial burden, prior trial participation and attitudinal barriers to clinical trials participation. Results of a factor analysis did not confirm the presence of the proposed four attitudinal barriers subscale/factors. Rather, a single factor represented the best fit to the data. The most highly-rated barriers were fear of side-effects, worry about health insurance and efficacy concerns. Results suggested that less educated patients, patients with non-metastatic disease, patients with no previous oncology clinical trial participation, and patients reporting greater perceived financial burden from cancer care were associated with higher barriers. These patients may need extra attention in terms of decisional support. Overall, patients with fewer personal resources (education, financial issues) report more attitudinal barriers and should be targeted for additional decisional support.

Abstract
PURPOSE To analyze 12- and 24-month visual acuity, intraocular pressure, and complications associated with combined pars plana vitrectomy (PPV) and glaucoma tube shunt placement in eyes with glaucoma. PATIENTS AND METHODS A retrospective chart review was performed of patients with advanced glaucoma who underwent combined PPV and tube shunt surgery from 2006 to 2010. A minimum of 12 months of follow-up was required for their inclusion in the study. Visual acuity, intraocular pressure, complications, and number of glaucoma medications at 1 and 2 years postoperatively were analyzed. RESULTS Twenty-eight eyes met the inclusion and exclusion criteria. Baseline visual acuity was 20/200 or worse in 14/28 eyes (50.0%) and 20/40 or better in 2/28 eyes (7.1%). Visual acuity remained 20/200 or worse in 50.0% (P=0.921) and 44.4% (P=0.973) of eyes after 1 and 2 years postoperatively, respectively. At baseline, the mean intraocular pressure was 30.4 mm Hg. There was significant improvement in mean IOP at 1 year (14.7 mm Hg, P=0.001) and at 2 years (15.2 mm Hg, P=0.001) postoperatively. Baseline number of glaucoma medications averaged 3.0±1.09 (SD), and improved to 1.8±1.28 (SD) at 1 year (P=0.0002) and to 1.4±1.33 at 2 years (P<0.0001) postoperatively. CONCLUSION In this retrospective interventional case series, surgical management of advanced glaucoma with a combination of PPV and glaucoma tube shunt resulted in significantly reduced IOP and glaucoma medications at 1 and 2 years postoperatively.

Abstract
Yogurt starter cultures may consist of multiple strains of Lactobacillus delbrueckii ssp. bulgaricus (LB) and Streptococcus thermophilus (ST). Conventional plating methods for monitoring LB and ST levels during yogurt manufacture do not allow for quantification of individual strains. The objective of the present work was to develop a quantitative PCR method for quantification of individual strains in a commercial yogurt starter culture. Strain-specific primers were designed for 2 ST strains (ST DGCC7796 and ST DGCC7710), 1 LB strain (DGCC4078), and 1 Lactobacillus delbrueckii ssp. lactis strain (LL; DGCC4550). Primers for the individual ST and LB strains were designed to target unique DNA sequences in clustered regularly interspersed short palindromic repeats. Primers for LL were designed to target a putative mannitol-specific IIbC component of the phosphotransferase system. Following evaluation of primer specificity, standard curves relating cell number to cycle threshold were prepared for each strain individually and in combination in yogurt mix, and no significant differences in the slopes were observed. Strain balance data was collected for yogurt prepared at 41 and 43°C to demonstrate the potential application of this method.

Abstract
Vitreomacular traction (VMT) syndrome and macular hole (MH) are disease processes that are caused by anomalous separation of the vitreous from the macula. Until now, management of these conditions has involved vitreoretinal surgery. Clinical trials have shown that a single intravitreal microplasmin (ocriplasmin) injection can induce separation of the vitreous from the macular surface and thereby relieve the tractional changes that contribute to vision loss from VMT and MH. Herein, we summarize the results of these trials which demonstrate that a significant number of intravitreal ocriplasmin-treated patients have resolution of their vitreoretinal interface abnormalities without the need for vitreoretinal surgery.

Abstract
Background: The Knowledge Program (KP) is an initiative to collect self-reported patient data and objective clinician assessments electronically at each outpatient clinical encounter. Available outcomes include the EuroQoL-5D (EQ5D), Patient Health Questionnaire-9 (PHQ9), Multiple Sclerosis Performance Scales (MSPS), and the timed 25-foot walk (T25FW). Objective: This study was designed to use the KP to investigate the long-term benefits of early treatment (ET) in multiple sclerosis (MS). Methods: The KP was queried for patients with relapsing–remitting MS or secondary progressive MS who were ≥5 years from symptom onset. ET was defined as treatment with an approved agent for ≥3 of the first five years after symptom onset. Propensity scores for ET were calculated based on early clinical characteristics. Patients were divided into propensity score quintiles and linear regression models were constructed to determine the treatment effect sizes and confidence intervals. Results: From the 1082 patients that met entry criteria, 453 patients (41.9%) received ET. Those patients receiving ET showed significantly better scores on the EQ5D index, PHQ9, and MSPS, but only in the upper three propensity quintiles. For the T25FW, ET did not result in significantly better times in any quintile. Conclusions: These results suggest that ET of MS is beneficial but the effect appears modest.

Abstract
Paid employment is valuable for society and for the individual. A diagnosis of a chronic illness such as multiple sclerosis (MS) can influence a person's employment status. Previous studies have reported that demographic and disease-related aspects can predict whether a person with MS will leave their job. The aim of the study was to assess the factors that people with MS believe to contribute to their employment status and to determine whether any of these differentiate people with MS who are employed from those who are not employed. A multinational questionnaire assessed aspects related to employment that facilitate or hinder job maintenance. Data was collected in 18 European countries. A total of 1,141 questionnaires were completed. Of those responding, 694 (61%) subjects were employed and 477 (39%) were unemployed. The items that significantly differentiated the groups were related to MS symptoms, workplace environment and financial considerations. While MS influences employment status for many people who face difficult symptoms, aspects like a flexible work schedule and financial security are important and perhaps key to promoting job maintenance among people with MS.

Abstract
Colicin E2 (ColE2) is a proteinaceous bacterial toxin produced by some strains of Escherichia coli and other members of the Enterobacteriaceae that exhibits inhibitory activity against some strains of E. coli O157:H7. A 2.0-kb DNA fragment, containing the ColE2 structural gene ceaB and immunity gene ceiB from E. coli NCTC 50133 (pColE2-P9), was cloned into the lactococcal plasmid vector pNZ2103. The lysis gene, celB, was not cloned. The plasmid, pLR-E2, encoding the cloned genes was transformed into E. coli DH5α and Lactococcus lactis ssp. lactis LM0230 and PN-1 using electroporation. The bacteriocin ColE2 was expressed in transformants of both E. coli and L. lactis ssp. lactis. Secretion of ColE2 into media was verified by spot-on-lawn assays and measurement of ColE2 activity in the growth medium of transformants. The level of ColE2 produced by transformants containing pLR-E2 was similar to that produced by the parental strain, E. coli NCTC 50133 (pColE2-P9). Evaluation of a ColE2-producing transformant of L. lactis ssp. lactis as a starter culture revealed that, although ColE2 was produced by transformants and could be detected in milk during fermentation, the inhibitory activity of ColE2 against E. coli O157:H7 was significantly decreased in milk compared with buffered growth medium.

Abstract
BACKGROUND A randomized, placebo-controlled, multicenter study of weekly intramuscular injections of interferon beta-1a (IFNβ-1a) in relapsing-remitting multiple sclerosis included the Sickness Impact Profile (SIP), a validated measure of patient-reported quality of life (QoL). OBJECTIVE To demonstrate the impact of moderate to severe SIP disability at baseline and change in QoL as measured by SIP over 2 years in relation to other study parameters. METHODS In 158 patients, SIP scores were determined at baseline and 2 years. Scores were correlated with disease progression and treatment. RESULTS Patients who experienced disability progression, as defined by Expanded Disability Status Scale (EDSS) and annualized relapse rate, during the study demonstrated significant worsening in Physical SIP scores compared with patients who did not progress (p=0.031). In patients with low SIP scores, indicating moderate or severe disability at baseline, treatment with IFNβ-1a significantly improved Physical SIP subscores. CONCLUSIONS Patients with disability progression defined using EDSS, the physician-derived primary outcome measure, had Physical SIP scores indicating worsening disability, validating the physician-derived primary outcome measure using patient self-report. Treatment with IFNβ-1a had beneficial effects on QoL in patients with worse SIP scores at baseline.

Abstract
BACKGROUND Optical imaging systems are robust, portable, relatively inexpensive, and have proven utility in detecting precancerous lesions in the lung, esophagus, colon, oral cavity and cervix. We describe the use of light-induced endogenous fluorescence (autofluorescence) in identifying preinvasive and occult carcinomas in ex vivo samples of human fallopian tube (FT) epithelium. METHODS Women undergoing surgery for an i) ovarian mass, ii) a history suggestive of hereditary breast-ovarian cancer, or iii) known serous ovarian cancer following neoadjuvant chemotherapy (NAC) were approached for informed consent. Immediately following surgery, FT's were photographed in reflectance and fluorescence at high resolution. Images included: (1) white-light reflectance of luminal/epithelial surface; (2) narrow-band green reflectance (570 nm) (3) green autofluorescence (405/436 nm excitation); and (4) blue autofluorescence (405 nm excitation). Areas revealing a loss of natural tissue fluorescence or marked increase in tissue microvasculature were recorded and compared to final histopathologic diagnosis (SEE-FIM protocol). RESULTS Fifty-six cases involving one or both fallopian tubes underwent reflectance and fluorescence visualization. Nine cases were excluded, either secondary to non-ovarian primary pathology (7) or excessive trauma (2) rendering tissue interpretation impossible. Of the 47 cases remaining, there were 11 high grade serous (HGS) and 9 non-serous ovarian carcinomas undergoing primary debulking surgery, 5 serous carcinomas having received NAC, 8 benign ovarian tumors, and 14 women undergoing risk-reducing bilateral salpingo-oophorectomy (RRBSO). Methodology was feasible, efficient, and reproducible. TIC or carcinoma was identified in 7/11 HGS, 3/5 NAC, and 1/14 RRBSO. Optical images were reviewed to determine test positive or negative based on standardized criteria. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for the entire cohort (73%; 83%; 57%; 91%) and in a subgroup that excluded non-serous histology (87.5%; 92%; 78%; 96%). CONCLUSIONS Abnormal FT lesions can be identified using ex vivo optical imaging technologies. With this platform, we will move towards genomic interrogation of identified lesions, and developing in vivo screening modalities via falloposcopy.

Abstract
OBJECTIVE No studies have addressed the use of electronic personal health records (e-PHRs) for self-management in complex neurological disorders. We assessed and tested an Internet-based self-management system that utilized the e-PHR and determined its impact on self-assessed well-being, clinician-assessed well-being, and healthcare utilization in patients with multiple sclerosis (MS). MATERIALS AND METHODS Subjects were randomized to usual care (a secure Web-based messaging system) or active intervention, which included secure messaging, self-monitoring, self-management of MS symptoms, and communication about upcoming clinic visits. Computers and Internet access were provided. Subjects were included if they had MS, lived within the county or region surrounding our MS center, had at least two appointments at our center in the previous 12 months, and demonstrated basic typing and computer skills. Study duration was 12 months. RESULTS Of 220 subjects completing informed consent, 206 met the inclusion criteria. At the study's end, 83 subjects remained in the usual care group and 84 in the enhanced care group. Both groups used the available system components. The groups did not significantly differ on the primary endpoints or healthcare utilization. CONCLUSIONS Self-management support is an emerging aspect of chronic care management. We established the feasibility of conducting a randomized, controlled trial using e-PHRs for patient self-management. We did not find that e-PHR-enabled self-management augmented multidisciplinary MS center-based care, possibly because the differences between interventions were not great enough.

Abstract
Multiple sclerosis (MS) is a complex demyelinating disease with a relatively unpredictable course. It is well established that MS has a significant impact on health-related quality of life (HRQL) for individuals at all stages of the disease. It is argued that clinicians offer treatment to their patients for three reasons: 1) to increase longevity, 2) to prevent future morbidity, and 3) to make patients feel better. To assess how well they are accomplishing the third of these goals, clinicians have come to depend on the direct measurement of patients' HRQL. We review the many physical and emotional symptoms and other consequences of MS that negatively influence HRQL, how HRQL is measured, the unique information these measures provide compared with clinical parameters, the benefit of treatment interventions, and how to include HRQL assessment and data from other sources in clinical encounters and suggest measures to consider for clinical use.

Abstract
OBJECTIVE To investigate the value of Expanded Disability Status Scale (EDSS) worsening sustained for at least 6 months and other parameters as predictors for disability status. DESIGN Retrospective analysis of the Multiple Sclerosis Collaborative Research Group study data. SETTING The intramuscular interferon beta-1a pivotal trial was a double-blind, placebo-controlled phase 3 study. PARTICIPANTS Patients with relapsing-remitting multiple sclerosis who received at least 2 years of treatment and completed an EDSS evaluation 8 years postrandomization. INTERVENTION Thirty micrograms of intramuscular interferon beta-1a or placebo once weekly during the 2-year clinical trial. MAIN OUTCOME MEASURES Positive predictive values for 6-month sustained progression during 2 years were calculated to determine the ability to predict disability status at 8 years. A multivariate logistic regression model was used to assess the relationship between predictors and EDSS milestones at follow-up. RESULTS Forty-five patients had sustained 6-month EDSS progression during the clinical trial and 115 did not. Progression during the trial was the strongest predictor of reaching EDSS milestones at the follow-up visit, 8 years after randomization. Other independent predictors were treatment arm assignment and baseline EDSS score. CONCLUSION In this phase 3 clinical trial of intramuscular interferon beta-1a, compared with effects of treatment, baseline EDSS score, and number of relapses during the study, worsening of 1 point or more on EDSS from baseline lasting 6 months was the strongest predictor of clinically significant disability 8 years after randomization into the clinical trial.
