Abstract

The hush puppy mouse mutant has been shown previously to have skull and outer, middle, and inner ear defects, and an increase in hearing threshold. The fibroblast growth factor receptor 1 (Fgfr1) gene is located in the region of chromosome 8 containing the mutation. Sequencing of the gene in hush puppy heterozygotes revealed a missense mutation in the kinase domain of the protein (W691R). Homozygotes were found to die during development, at approximately embryonic day 8.5, and displayed a phenotype similar to null mutants. Reverse transcription PCR indicated a decrease in Fgfr1 transcript in heterozygotes and homozygotes. Generation of a construct containing the mutation allowed the function of the mutated receptor to be studied. Immunocytochemistry showed that the mutant receptor protein was present at the cell membrane, suggesting normal expression and trafficking. Measurements of changes in intracellular calcium concentration showed that the mutated receptor could not activate the IP3 pathway, in contrast to the wild-type receptor, nor could it initiate activation of the Ras/MAP kinase pathway. Thus, the hush puppy mutation in fibroblast growth factor receptor 1 appears to cause a loss of receptor function. The mutant protein appears to have a dominant negative effect, which could be due to it dimerising with the wild-type protein and inhibiting its activity, thus further reducing the levels of functional protein. A dominant modifier, Mhspy, which reduces the effect of the hush puppy mutation on pinna and stapes development, has been mapped to the distal end of chromosome 7 and may show imprinting. © Springer Science+Business Media, LLC 2011.

Abstract

The SENTINEL study showed that the addition of natalizumab improved outcomes for patients with relapsing multiple sclerosis (MS) who had experienced disease activity while receiving interferon beta-1a (IFNbeta-1a) alone. Previously unreported secondary and tertiary magnetic resonance imaging (MRI) measures are presented here. Patients received natalizumab 300 mg (n=589) or placebo (n=582) intravenously every 4 weeks plus IFNbeta-1a 30 microg intramuscularly once weekly. Annual MRI scans allowed comparison of a range of MRI end points versus baseline. Over 2 years, 67% of patients receiving natalizumab plus IFNbeta-1a remained free of new or enlarging T2-lesions compared with 30% of patients receiving IFNbeta-1a alone. The mean change from baseline in T2 lesion volume over 2 years decreased in patients receiving natalizumab plus IFNbeta-1a and increased in those receiving IFNbeta-1a alone (-277.5mm(3) versus 525.6mm(3); p0.001). Compared with IFNbeta-1a alone, add-on natalizumab therapy resulted in a smaller increase in mean T1-hypointense lesion volume after 2 years (1821.3mm(3) versus 2210.5mm(3); p0.001), a smaller mean number of new T1-hypointense lesions over 2 years (2.3 versus 4.1; p0.001), and a slower rate of brain atrophy during the second year of therapy (-0.31% versus -0.40%; p=0.020). Natalizumab add-on therapy reduced gadolinium-enhancing, T1-hypointense, and T2 MRI lesion activity and slowed brain atrophy progression in patients with relapsing MS who experienced disease activity despite treatment with IFNbeta-1a alone.

Abstract

HGF/SF and HGF1/MSP define a novel growth factor family whose members share the domain structure and the proteolytic process of activation of the blood proteinase precursor plasminogen. The amino acid and RNA sequences of HGF/SF and HGF1/MSP, the intron-exon organization of their genes and the predicted 3D structure of individual domains indicate that HGF/SF and HGF1/MSP evolved along with plasminogen and other members of the kringle-serine proteinase (KSP) superfamily from an ancestral gene that contained a single copy of the kringle domain, a serine proteinase domain and an activation peptide connecting the two domains. A series of intragenic duplications of the kringle domain, gene duplications, exon shuffling and deletions is responsible for the genes currently present in mammals, avians and amphibians. Plasminogen, HGF/SF and HGF1/MSP represent paradigmatic examples of the modern, multi-domain proteins typically associated with vertebrate organisms and illustrate a novel evolutionary pathway that led to the emergence of molecules with growth regulatory activity from proteolytic enzymes.

Abstract

Objective: To determine the incidence and clinical effects of antibodies that develop during treatment with natalizumab. Methods: In two randomized, double-blind, placebo-controlled studies (natalizumab safety and efficacy in relapsing remitting multiple sclerosis [MS, AFFIRM] and safety and efficacy of natalizumab in combination with interferon β-1a [INFβ1a] in patients with relapsing remitting MS [SENTINEL]) of patients with relapsing multiple sclerosis, blood samples were obtained at baseline and every 12 weeks to determine the presence of antibodies against natalizumab. Antibodies to natalizumab were measured using an ELISA. Patients were categorized as “transiently positive” if they had detectable antibodies (≥0.5 μg/mL) at a single time point or “persistently positive” if they had antibodies at two or more time points ≥6 weeks apart. Results: In the AFFIRM study, antibodies were detected in 57 of 625 (9%) of natalizumab-treated patients: Twenty (3%) were transiently positive and 37 (6%) were persistently positive. Persistently positive patients showed a loss of clinical efficacy as measured by disability progression ( p ≤ 0.05), relapse rate ( p = 0.009), and MRI ( p ≤ 0.05) compared with antibody-negative patients. In transiently positive patients, full efficacy was achieved after approximately 6 months of treatment, the time when patients were becoming antibody negative. The incidence of infusion-related adverse events was significantly higher in persistently positive patients. Results of SENTINEL were similar to AFFIRM, except with regard to sustained disability progression; differences between persistently positive and antibody-negative patients were not statistically significant. Conclusions: The incidence of persistent antibody positivity associated with natalizumab is 6%. Reduced clinical efficacy is apparent in persistently positive patients. Patients with a suboptimal clinical response or persistent infusion-related adverse events should be considered for antibody testing.

Abstract

Objective To report the relationship between disease activity and health-related quality of life (HRQoL) in relapsing multiple sclerosis, and the impact of natalizumab. Methods HRQoL data were available from 2,113 multiple sclerosis patients in natalizumab clinical studies. In the Natalizumab Safety and Efficacy in Relapsing Remitting Multiple Sclerosis (AFFIRM) study, patients received natalizumab 300mg (n = 627) or placebo (n = 315); in the Safety and Efficacy of Natalizumab in Combination with Interferon Beta-1a in Patients with Relapsing Remitting Multiple Sclerosis (SENTINEL) study, patients received interferon beta-1a (IFN-β-1a) plus natalizumab 300mg (n = 589), or IFN-β-1a plus placebo (n = 582). The Short Form-36 (SF-36) and a subject global assessment visual analog scale were administered at baseline and weeks 24, 52, and 104. Prespecified analyses included changes from baseline to week 104 in SF-36 and visual analog scale scores. Odds ratios for clinically meaningful improvement or worsening on the SF-36 Physical Component Summary (PCS) and Mental Component Summary were calculated. Results Mean baseline SF-36 scores were significantly less than the general US population and correlated with Expanded Disability Status Scale scores, sustained disability progression, relapse number, and increased volume of brain magnetic resonance imaging lesions. Natalizumab significantly improved SF-36 PCS and Mental Component Summary scores at week 104 in AFFIRM. PCS changes were significantly improved by week 24 and at all subsequent time points. Natalizumab-treated patients in both studies were more likely to experience clinically important improvement and less likely to experience clinically important deterioration on the SF-36 PCS. The visual analog scale also showed significantly improved HRQoL with natalizumab. Interpretation HRQoL was impaired in relapsing multiple sclerosis patients, correlated with severity of disease as measured by neurological ratings or magnetic resonance imaging, and improved significantly with natalizumab.

Abstract

Background Interferon beta is used to modify the course of relapsing multiple sclerosis. Despite interferon beta therapy, many patients have relapses. Natalizumab, an α 4 integrin antagonist, appeared to be safe and effective alone and when added to interferon beta-1a in preliminary studies. Methods We randomly assigned 1171 patients who, despite interferon beta-1a therapy, had had at least one relapse during the 12-month period before randomization to receive continued interferon beta-1a in combination with 300 mg of natalizumab (589 patients) or placebo (582 patients) intravenously every 4 weeks for up to 116 weeks. The primary end points were the rate of clinical relapse at 1 year and the cumulative probability of disability progression sustained for 12 weeks, as measured by the Expanded Disability Status Scale, at 2 years. Results Combination therapy resulted in a 24 percent reduction in the relative risk of sustained disability progression (hazard ratio, 0.76; 95 percent confidence interval, 0.61 to 0.96; P = 0.02). Kaplan–Meier estimates of the cumulative probability of progression at two years were 23 percent with combination therapy and 29 percent with interferon beta-1a alone. Combination therapy was associated with a lower annualized rate of relapse over a two-year period than was interferon beta-1a alone (0.34 vs. 0.75, P

28. Experimental shadowing measurements on randomly-rough surfaces.

Author

Welton, P. J., Hawker, K. E., and Frey, H. G.

Abstract

The dependence of the shadowing function on grazing angle was optically measured on three rough surfaces which are identical except for the rms reliefs (and slopes) which had been scaled in the ratios 1 : 2 : 4. Both one- and two-dimensional shadowing measurements were made. The one-dimensional measurements are in good agreement with the one-dimensional theory of shadowing developed by R. J. Wagner. In addition, the one- and two-dimensional shadowing measurements are in excellent agreement with one another as would be expected for nearly isotropic surfaces. [ABSTRACT FROM AUTHOR]

Abstract

B cells have recently been identified as an integral component of the immune system; they play a part in autoimmunity through antigen presentation, antibody secretion, and complement activation. Animal models of multiple sclerosis (MS) suggest that myelin destruction is partly mediated through B cell activation (and plasmablasts). MS patients with evidence of B cell involvement, as compared to those without, tend to have a worse prognosis. Finally, the significant decrease in new gadolinium-enhancing lesions, new T2 lesions, and relapses in MS patients treated with rituximab (a monoclonal antibody against CD20 on B cells) leads us to the conclusion that B cells play an important role in MS and that immune modulation of these cells may ameliorate the disease. This article will explore the role of B cells in MS and the rationale for the development of B cell-targeted therapeutics. MS is an immune-mediated disease that affects over 2 million people worldwide and is the number one cause of disability in young patients. Most therapeutic targets have focused on T cells; however, recently, the focus has shifted to the role of B cells in the pathogenesis of MS and the potential of B cells as a therapeutic target.

Abstract

This article discusses the main principles of infection prevention and control in non-acute healthcare settings. It explores the use of a set of ten tools developed by the Infection Control Nurses Association (ICNA) to audit infection prevention and control, using the standard statements and criteria within the tools as a checklist. The results of the audit of facilities, commodities and practice using the ICNA audit tools will help staff to identify areas of best practice and areas where improvements are needed to enhance patient care.

Abstract

Background: Mycophenolate mofetil (MMF) is an oral DNA base synthesis inhibitor with immunomodulatory effects on B cells, T cells, and macrophages. Objective: To conduct a safety and tolerability pilot study of interferon beta-1a (IFN-b1a) in combination with either placebo or oral MMF in multiple sclerosis (MS). Methods: Twenty-four treatment-naïve R—RMS patients participated in a one-year prospective, placebo-controlled, blinded, safety pilot clinical trial. Every patient injected weekly intramuscular interferon beta-1a. The cohort was then randomized (1 : 1) to either active oral MMF or identical-appearing placebo tablets. Clinical evaluations were assessed every 3 months, along with brain MRI scans performed at baseline and repeated every 60 days for one year. Comprehensive laboratory assessments were monitored for safety, along with adverse events. Results: In this small pilot investigation, no differences were identified between the two treatment groups with respect to patient-reported adverse events, MRI metrics, or laboratory abnormalities. Notwithstanding these observations, and the limited number of patients treated, trends appeared to favor the combination therapy regimen. Conclusions: The combination treatment regimen of interferon beta-1a and MMF appeared to be well tolerated in this pilot study. Despite the small sample size, therapeutic trends were observed in favor of combination therapy. An adequately powered controlled trial of MMF in MS appears warranted.

Abstract

Advancements in imaging technologies and newly evolving treatments offer the promise of more effective management strategies for MS. Until recently, confirmation of the diagnosis of MS has generally required the demonstration of clinical activity that is disseminated in both time and space. Nevertheless, with the advent of MRI techniques, occult disease activity can be demonstrated in 50 to 80% of patients at the time of the first clinical presentation. Prospective studies have shown that the presence of such lesions predicts future conversion to clinically definite (CD) MS. Indeed, in a young to middle-aged adult with a clinically isolated syndrome (CIS), once alternative diagnoses are excluded at baseline, the finding of three or more white matter lesions on a T2-weighted MRI scan (especially if one of these lesions is located in the periventricular region) is a very sensitive predictor (>80%) of the subsequent development of CDMS within the next 7 to 10 years. Moreover, the presence of two or more gadolinium (Gd)-enhancing lesions at baseline and the appearance of either new T2 lesions or new Gd enhancement on follow-up scans are also highly predictive of the subsequent development of CDMS in the near term. By contrast, normal results on MRI at the time of clinical presentation makes the future development of CDMS considerably less likely.

Abstract

Objective: The objective of this study was to determine the impact of multiple sclerosis (MS) disease-modifying therapies (DMTs) on the development of cellular and humoral immunity to severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection., Methods: Patients with MS aged 18 to 60 years were evaluated for anti-nucleocapsid and anti-Spike receptor-binding domain (RBD) antibody with electro-chemiluminescence immunoassay; antibody responses to Spike protein, RBD, N-terminal domain with multiepitope bead-based immunoassays (MBI); live virus immunofluorescence-based microneutralization assay; T-cell responses to SARS-CoV-2 Spike using TruCulture enzyme-linked immunosorbent assay (ELISA); and IL-2 and IFNγ ELISpot assays. Assay results were compared by DMT class. Spearman correlation and multivariate analyses were performed to examine associations between immunologic responses and infection severity., Results: Between January 6, 2021, and July 21, 2021, 389 patients with MS were recruited (mean age 40.3 years; 74% women; 62% non-White). Most common DMTs were ocrelizumab (OCR)-40%; natalizumab -17%, Sphingosine 1-phosphate receptor (S1P) modulators -12%; and 15% untreated. One hundred seventy-seven patients (46%) had laboratory evidence of SARS-CoV-2 infection; 130 had symptomatic infection, and 47 were asymptomatic. Antibody responses were markedly attenuated in OCR compared with other groups (p ≤0.0001). T-cell responses (IFNγ) were decreased in S1P (p = 0.03), increased in natalizumab (p <0.001), and similar in other DMTs, including OCR. Cellular and humoral responses were moderately correlated in both OCR (r = 0.45, p = 0.0002) and non-OCR (r = 0.64, p <0.0001). Immune responses did not differ by race/ethnicity. Coronavirus disease 2019 (COVID-19) clinical course was mostly non-severe and similar across DMTs; 7% (9/130) were hospitalized., Interpretation: DMTs had differential effects on humoral and cellular immune responses to SARS-CoV-2 infection. Immune responses did not correlate with COVID-19 clinical severity in this relatively young and nondisabled group of patients with MS. ANN NEUROL 2022;91:782-795., (© 2022 The Authors.

Abstract

Objective: Patients with rheumatic diseases often have multiple comorbidities which may impact well-being leading to high psychosocial complexity. This scoping review was undertaken to identify complexity measures/tools used in rheumatology that could help in planning and coordinating care., Methods: MEDLINE, EMBASE and CINAHL were searched from database inception to 14 December 2019 using keywords and Medical Subject Headings for "care coordination", "complexity" and selected rheumatic diseases and known complexity measures/tools. Articles describing the development or use of complexity measures/tools in patients with adult rheumatologic diagnoses were included regardless of study design. Included articles were evaluated for risk of bias where applicable., Results: The search yielded 407 articles, 37 underwent full-text review and 2 were identified during a hand search with 9 included articles. Only 2 complexity tools used in populations of adult patients with rheumatic disease were identified: the SLENQ and the INTERMED. The SLENQ is a 97-item patient needs questionnaire developed for patients with systemic lupus (n = 1 study describing tool development) and applied in 5 cross-sectional studies. Three studies (a practice article, trial and a cross-sectional study) applied the INTERMED, a clinical interview to ascertain complexity and support coordinated care, in patients with rheumatologic diagnoses., Conclusions: There is limited information on the use of patient complexity measures/tools in rheumatology. Such tools could be applied to coordinate multidisciplinary care and improve patient experience and outcomes., Patient Contribution: This scoping review will be presented to patient research partners involved in co-designing a future study on patient complexity in rheumatic disease., (© 2021 The Authors.

Abstract

Workplace exposure to suicide attempts and deaths has been widely recognized as an occupational hazard for mental health and social care workers, including mental health nurses. Research consistently demonstrates the adverse impact on professionals. This paper explores the results of an online survey examining suicide exposure and impact. Of the 3010 Australian adult participants who identified exposure to suicide attempts and/or deaths in a larger study, 130 indicated that the most impactful suicide attempt and/or death exposure was that of a client or service user. While distress levels were relatively low among participants with workplace exposure, the qualitative content from 53 participants provides illumination into this experience. Themes that emerged in the qualitative responses include impact on the professional, organization response, and lack of adequate resources and supports to prevent suicide. Previous research has examined the impact of suicide exposure among professionals specifically, but this is the first known study of participants in a community sample who identified the most impactful suicide attempt or death exposure they had experienced was that of a client in a mental health setting. Workplace exposure among mental health workers is common and can have both deleterious and positive effects. Bereavement focused outcomes, where the loss of an attachment relationship is the focus, does not capture the full range of experiences in workplace exposure. Systemic issues in mental health care contribute to further distress among exposed workers, and this requires additional investigation and response., (© 2020 Australian College of Mental Health Nurses Inc.)

Abstract

Background: Fingolimod is a once-daily, orally administered therapy for relapsing forms of MS. It has been shown to reduce relapse rates significantly in all phase II and phase III clinical trials when compared with placebo and intramuscular interferon β-1a (IFNβ-1a IM)., Methods: This study compared annualized relapse rates (ARRs) associated with fingolimod, placebo and IFNβ-1a IM, in patient subgroups from the pooled FREEDOMS, FREEDOMS II, and TRANSFORMS populations. This provided a large data set in which the efficacy of fingolimod could be assessed across a range of patient subgroups, including clinically relevant subgroups not previously analysed., Results: Compared with placebo, fingolimod was associated with significantly lower ARRs across all patient subgroups with relative reductions in ARRs ranging from 35% (patients who had previously received treatment for their MS for up to 1 year; P<0.05) to 69% (patients with symptoms for less than 3 years before study entry; P<0.001). Other relative reductions in ARR compared with placebo included 64% in patients aged 40 years or younger and 63% in those naïve to treatment (P<0.001 for both). Compared with IFNβ-1a IM, the greatest benefits to ARR were seen in patients aged 40 years or younger (55% relative ARR reduction, P<0.001) and in a small subgroup of patients who had previously received IFNβ and glatiramer acetate (55% relative ARR reduction; P<0.05). Reductions in ARR compared with IFNβ-1a IM were not statistically significant in men (33%, P=0.081), in patients aged over 40 years (23%, P=0.230) and in those who had received treatment prior to the study for 1 year or less (35%, P=0.108). Fingolimod was associated with significantly lower ARRs compared with placebo and with IFNβ-1a IM irrespective of treatment status (treatment-naïve and previously treated for MS), and regardless of type of previous therapy., Conclusions: Fingolimod provided consistent efficacy benefits over placebo and IFNβ-1a IM across a range of subgroups of patients with relapsing MS. The magnitude of the beneficial effect of fingolimod over IFNβ-1a IM may depend on age, sex, and duration of previous treatment. These findings suggest that most benefit will be gained by patients who start fingolimod early in the disease course, but the findings also suggest that fingolimod treatment will benefit patients later in the disease course when they have already accrued disability., (Copyright © 2016 The Authors.

Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurological disease characterized by degeneration and death of motor neurons. Aberrant protein aggregation and oxidative stress are implicated in the etiology of ALS; thus preventing propagation of early aggregation events and oxidative damage could be an effective therapy. We tested the effect of dietary supplementation (initiated 40 days of age) with 2-(2-hydroxyphenyl)-benzoxazole (HBX), a compound with metal chelator and anti-aggregation properties, on disease onset, progression and lifespan in the G93A mouse model of ALS. Tests were not sufficiently powerful to detect any change to survival distribution of mice treated with HBX. However, the disease onset was delayed and max lifespan was increased in the treatment group. Additionally, disease progression was moderated as shown by reduced neuromuscular denervation measured by repetitive nerve stimulation. F2-isoprostanes, a marker of oxidative damage, are elevated in skeletal muscle from G93A mice at onset and this increase is prevented in HBX fed G93A mice. Furthermore, HBX treatment reduced mutant SOD1 protein aggregation in whole spinal cord of G93A mice at disease onset. Overall, our data suggests that HBX may be able to improve the degenerative symptoms of ALS through the prevention of oxidative damage and protein aggregation. Further studies are needed to uncover the mechanistic effects of HBX in ameliorating ALS pathology., (Copyright © 2016. Published by Elsevier Ireland Ltd.)

Abstract

Fingolimod is an orally administered, first-in-class therapy for the treatment of relapsing forms of multiple sclerosis. Data from pivotal clinical trials show that fingolimod has a robust, significant effect on annualized relapse rates and MRI outcomes. Fingolimod has a novel, well-characterized mechanism of action. It acts through a specific set of receptors, sphingosine 1-phosphate receptors, present on the surface of a wide range of human cells and tissues, including neural cells, neurons and lymphocytes. Here we review the current literature to describe the mechanism of action of fingolimod in the context of its well-established clinical efficacy and safety profile. Understanding of the mechanisms behind any non-therapeutic effects of fingolimod facilitates their prediction and management in the clinical setting.

Abstract

The hush puppy mouse mutant has been shown previously to have skull and outer, middle, and inner ear defects, and an increase in hearing threshold. The fibroblast growth factor receptor 1 (Fgfr1) gene is located in the region of chromosome 8 containing the mutation. Sequencing of the gene in hush puppy heterozygotes revealed a missense mutation in the kinase domain of the protein (W691R). Homozygotes were found to die during development, at approximately embryonic day 8.5, and displayed a phenotype similar to null mutants. Reverse transcription PCR indicated a decrease in Fgfr1 transcript in heterozygotes and homozygotes. Generation of a construct containing the mutation allowed the function of the mutated receptor to be studied. Immunocytochemistry showed that the mutant receptor protein was present at the cell membrane, suggesting normal expression and trafficking. Measurements of changes in intracellular calcium concentration showed that the mutated receptor could not activate the IP(3) pathway, in contrast to the wild-type receptor, nor could it initiate activation of the Ras/MAP kinase pathway. Thus, the hush puppy mutation in fibroblast growth factor receptor 1 appears to cause a loss of receptor function. The mutant protein appears to have a dominant negative effect, which could be due to it dimerising with the wild-type protein and inhibiting its activity, thus further reducing the levels of functional protein. A dominant modifier, Mhspy, which reduces the effect of the hush puppy mutation on pinna and stapes development, has been mapped to the distal end of chromosome 7 and may show imprinting.

Abstract

Progressive multiple sclerosis (MS) consists of 3 phenotypic subtypes: secondary progressive MS, primary progressive MS, and progressive relapsing MS. There has been a paucity of approved treatments for these subtypes possibly driven by irreversible neurodegeneration within the central nervous system and not amenable to drugs that target inflammation. This article reviews magnetic resonance imaging and clinical data that show that progression may occur early in the course of MS and specific subsets of progressive patients may respond to disease modifying drugs., (Copyright © 2011 Elsevier Inc.
