Meta-analysis of the relationship between multiple sclerosis and migraine.

Immune therapies used to treat MS may also a have a role as evidence for a migraine-inducing role of interferon beta exists [24], however, immune therapies could only ever provide a small part of the complete explanation due to the fact that migraine often precedes MS. Interferon beta treatment is also thought to worsen pre-existing migraine, suggesting it may not be implicated in the aetiology of the migraine itself [25]. Notably, evidence suggests that the other disease modifying therapies glatiramer acetate and natalizumab do not appear to worsen migraine, and indeed some patients may want to take this into consideration as switching from interferon beta may help reduce both frequency and severity of migraine [26–27]. Furthermore, stress and anxiety, which often accompany MS, are thought to be very likely causes of increased migraine frequency and chronification [28]. One further suggestion is that instead of one condition causing the other, both conditions have a common pathway in their underlying cause.

Basal cortisol levels and the relationship with clinical symptoms in multiple sclerosis: a systematic review

Basal cortisol levels and the relationship with clinical symptoms in multiple sclerosis: a systematic review

Articles that described assessment characteristics and sample storage did this according to instructions provided by manufacturers of the respective commercial kits. Nevertheless, many studies did not clarify the duration of storage and did not use sample randomization, which made comparison of results among the studies and validity of processing more difficult and increased the bias risk. Similarly, the choice of an accurate and systematic recruitment in case control studies needed to be obtained in the light of data of healthy individuals and patients without MS, who presented for an investigated condition, such as depression. Furthermore, results in some articles were just described as higher or lower, without ever showing mean val- ues found in each group.

Relationship between auditory-perceptual and self- assessment measures in patients with multiple sclerosis

Relationship between auditory-perceptual and self- assessment measures in patients with multiple sclerosis

Purpose: To determine the relationships between auditory-perceptual and self-assessment measures in patients with multiple sclerosis with and without vocal complaints. Methods: Eighteen subjects diagnosed with multiple sclerosis, including 12 women and 6 men aged between 21 to 67 years, participated in the study. A brief anamnesis, the Voice Symptom Scale and the Living with Dysarthria questionnaire were completed, followed by recording of the sustained /ԑ/ vowel. The overall severity of vocal deviation and the degrees of roughness, breathiness, strain and instability were assessed by three speech therapists using a 100-mm visual analogue scale. Results: Patients with multiple sclerosis and vocal complaints had higher Total (p= 0.026) and Limitation (p= 0.042) scores on the Voice Symptom Scale and on sections one (p= 0.041), four (p= 0.030) and ten (p= 0.050) of the Living with Dysarthria questionnaire. Strong positive correlations were found between the Total and Limitation scores of the Voice Symptom Scale and the scores of sections one, four and nine of the Living with Dysarthria questionnaire. Conclusion: Patients with multiple sclerosis and vocal complaints have higher frequencies of symptom occurrence and emotional and speech effects. No relationship was found between auditory-perceptual and self-assessment measures in patients with multiple sclerosis. However, the scores on the two self-assessment instruments used are strongly correlated.

Multiple correspondence analysis applied to the study of the relationship between traffic crashes and precipitation on a highway in Brazil

Multiple correspondence analysis applied to the study of the relationship between traffic crashes and precipitation on a highway in Brazil

The Serra do Mar is a Brazilian mountain range with an average extension of 2,000.0 km, from the Rio de Janeiro state to Santa Catarina state. The area is characterized by a strongly undulated relief and considerable number of natural and arti(icial slopes (Victorino et al., 2017). Moreover, BR-376 Highway is an important traf(ic route for Brazilian products and passenger transports. This region has great economical and strategical importance, since it connects the exporting and importing port area and the most industrialized and populated regions of Brazil. Therefore, the area is intensely transposed by highways, railways and oil pipelines (HASUI et al., 2012). It is important to highlight that, due to the region relief, the highways presented in the Serra do Mar have highly curved sections, which are considered as dangerous passages.

The effect of disease modifying therapies on brain atrophy in patients with relapsing-remitting multiple sclerosis: a systematic review and meta-analysis.

The effect of disease modifying therapies on brain atrophy in patients with relapsing-remitting multiple sclerosis: a systematic review and meta-analysis.

Systematic search of MEDLINE and SCOPUS databases yielded 60 and 57 results respectively. Subsequent search in the CENTRAL Register of Controlled Trials retrieved no additional RCTs. After removing duplicates, the titles and abstracts from the remaining 75 studies were screened and 17 potentially eligible studies for the meta-analysis were retained. After retriev- ing the full-text version of the aforementioned 17 studies, 4 studies were excluded because they did not include a placebo subgroup and 2 studies because they were not RCT (cohort studies), 6 studies because they reported the brain volume changes in median values and 1 study because it did not report the SDs or other measures of dispersion (Table A in S1 File). In the final presentation of the literature search results, there was no conflict or disagreement between the 2 reviewers and the 4 studies that met the study protocol’s inclusion criteria (IMPROVE [7], FREEDOMS [8], E/C GASG [9], MSCRG [10]) were included both in the qualitative and quantitative synthesis (Fig. 1). The characteristics of the included studies, com- prising 1819 patients (71% women, mean age: 36.5 years, mean baseline EDSS score: 2.4) are summarized in Table 1.

The relationship between anti-merozoite antibodies and incidence of Plasmodium falciparum malaria: A systematic review and meta-analysis.

The relationship between anti-merozoite antibodies and incidence of Plasmodium falciparum malaria: A systematic review and meta-analysis.

IgG responses to some, but not all, merozoite surface antigens were associated with protection against symptomatic P. falciparum in malaria endemic areas. We identified very few antigens that had been well studied and a deficiency of studies done outside Africa. More studies in different populations, examining multiple antigens at multiple time-points, are needed to better determine the role of anti-merozoite antibodies in protection against malaria, with prospective cohort studies as the preferred study design to establish temporal causality. In the future, there should be as much uniformity between studies as possible to ensure maximum comparability. This could be improved by the quantification and standardization of IgG responses, which could be achieved by establishing a reference reagent for determining antibody concentrations. Furthermore, the protective effects of anti- merozoite responses observed epidemiologically must also be supported by evidence of the function of the antibodies. Development and application of functional assays rather than standard immunoassays would also be highly valuable. Presently, data on the function of antibodies against merozoite antigens is very limited [8,12,15,72]. Lastly, there is a need to incorporate strain-specific responses and endpoints to address whether protective responses against particular antigens are strain-tran- scending or strain-specific.

Abstract: This research is justified by the need to broaden the theory about consumer behavior in tourism and the importance of improving commercial practices. The main objective of this study is to analyze the relation- ship between the search for happiness in the tourist experience and the desire for local hospitality, mediated by the congruence between the tourist's self-image and the destination image. A survey yielded 221 completed questionnaires. We took a quantitative approach to data analysis using multiple linear regression technique, and the results indicate a significant and positive relationship between the search for happiness in the tourist experience and the desire for local hospitality, mediated by the congruence of tourists self-image (how they see themselves) and tourist destination image. The originality of this study is to identify the self-image of the tour- ist and tourist destination as factors mediating the perception of local hospitality.

Relationship between interleukin-10 -1082A/G polymorphism and risk of ischemic stroke: a meta-analysis.

Relationship between interleukin-10 -1082A/G polymorphism and risk of ischemic stroke: a meta-analysis.

Sensitivity analysis was conducted to evaluate the stability of the results. After excluding the study deviating from HWE[10], statistically significant associations were observed for Asians under all the genetic models (A VS.G: OR 1.64, 95% CI 1.07–2.53, P = 0.02; AA vs. GG: OR 1.91, 95% CI 1.31–2.80,P = 0.0008; AG vs. GG: OR1.44, 95% CI 1.09–1.91,P = 0.01 AA+AG vs. GG: OR1.54, 95% CI 1.18–2.01,P = 0.001,AA VS. AG+GG: OR 1.79, 95% CI 1.07–3.00, P = 0.03, whereas the corresponding pooled ORs of total available studies which meant overall analysis for all ethnicities were not materially altered (data not shown), except in recessive model(AA VS. AG+GG OR 1.58, 95% CI 1.04–2.42, P = 0.03). However, after Bonferronic correction for multiple testing, the associations revealed still significantly in Asian subgroup under homozygote and dominant models (AA vs. GG: OR 1.91, 95% CI 1.31–2.80, P = 0.0008; AA+AG vs. GG: OR1.54, P = 0.001). The results indicated that the homozygote AA and A allele carriers (AA+AG) had nearly a 91% and 54% increased risk of IS respectively, when compared with the homozygote GG in Asians. In particular, removing the study which was deviated from HWE eliminated the heterogeneity in subgroup analysis of Asians in homozygote, heterozygote, and dominant models, but not in the allele and recessive models and the pooling analysis (The results were shown in Table 3 and Figure 3.).Moreover, omitting the other 6 eligible studies one by one, the corresponding pooled ORs in overall comparisons and subgroup analysis were not significantly changed and the significant heterogeneity between studies still existed (data not shown).

An updated meta-analysis of risk of multiple sclerosis following infectious mononucleosis.

An updated meta-analysis of risk of multiple sclerosis following infectious mononucleosis.

We used the generic inverse variance with random effects model in Reference Manager 5.0 to calculate the overall RR, 95% CI and test statistic for the interaction and heterogeneity of studies. RRs were subsequently calculated for subgroups of studies and compared between case-control and cohort studies, and studies using definite MS diagnostic criteria and those using definite/ probable MS. We extracted latitude from papers based on either the latitude of the study centre if performed in a distinct region or the geographical midpoint of the country if a national study. We tested for an interaction between latitude and sex-ratio by both a comparison of RRs based on the median value for each factor and also performed linear weighted fit on the natural log of RRs in Mathematica 7.0.1.0.

Objective: To analyse the relationship between the social support network (SSN) and health related quality of life (HRQOL) in multiple sclerosis (MS) patients. Methods: The sample comprised 150 consecutive MS patients attending our MS clinic. To assess the socio-demographic data, a specifically designed questionnaire was applied. The HRQOL dimensions were measured with the Short-Form Health Survey Questionnaire-SF36 and the SSN with the Medical Outcomes Study Social Support Survey. Spearman’s correlation was used to compare the magnitude of the relationship between the SSN and HRQOL. Results: The mean patient age was 41.7 years (± 10.4; range: 18–70 yr); the mean Expanded Disability Status Score was 2.5 (±2.4; range: 0–9). There was a statistically significant correlation between the structure of the SSN and the HRQOL. Conclusion: The composition of the SSN, social group membership and participation in voluntary work have an important role in the HRQOL of patients with MS.

Determinants and Consequences of   the Website Perceived Value

Determinants and Consequences of the Website Perceived Value

To the commercial website, telepresence is the equivalent of general and internal variables. According to Sheridan (1992), Steuer (1995), Biocca (1997), Lombard and Ditton (1997) and Shith (1998), the telepresence concept is used to describe the gratifying sense to be present in a mediated environment which appears as it naturally was. Hoffman and Novak (1996), Novak, Hoffman and Yung (1999) assert that telepresence is the perception that the virtual environment, with which the user is in interaction, is more real and dominant than the physical environment. Volle (2000), as for him, highlights that the principle challenges landed by the virtual atmosphere consist to maintain a high attention and a fluidity sensation that captures the visitor. Thus, a site with captivating content is the one that allows visitors to live a telepresence experience. During this research, we consider the steuer (1992)’s conceptualization of telepresence envisioning this later as “The extent to which one feels present in the mediated environment rather than in the immediate physical environment”. In other words, telepresence refers to the mediated perception of an environment that can be a spatially distant, real environment, or a virtual world.

The Impact of E-Commerce Securi ty, and National Environment  on Consumer adoption of Intern et Banking in Malaysia and  Singapore

The Impact of E-Commerce Securi ty, and National Environment on Consumer adoption of Intern et Banking in Malaysia and Singapore

Relative advantage is defined as the extent to which a person views an innovation as offering an advantage over previous ways of performing the same task (Roger, 1983; Agarwal & Prasad, 1997). Because Internet banking services allow customers to access their banking account from any location 24 hours a day and 7 days a week, it provides an enormous advantage and convenience to users (Tan & Teo, 2000). It also gives customers greater control over managing their finances, as they are able to check their accounts easily. Besides, a customer’s Internet experience, his or her banking needs can affect his adoption. As there are more financial products and services, it is expected that individuals with many financial accounts and who subscribe to many banking services will be more inclined to adopt Internet banking. Tan and Teo (2000) has reported that potential adopters of Internet banking services are likely to own multiple banking accounts and subscribe to various banking services. Rogers argues that potential adapters, who are allowed to experiment with an innovation will feel more comfortable with the innovation and are more likely to adopt it. Thus, if customers have the opportunity to try the innovation, certain fears of the unknown may be minimized. Government policy could also aid or hinder Internet diffusion (Mbarika, 2002). This is consistent with the national systems of innovation theory that posits that government policies may encourage or mandate technology development and adoption (King et. al., 1994; Wolcott et. al., 2001). Tan and Teo (2000) suggest that the greater the extent of government support for Internet commerce, the more likely Internet banking will be adopted, thus, confirming Goh’s (1995) suggestion that governments can play an interventionist and leading role in the diffusion of innovation. Potential users in turn would view new applications such as Internet banking services more favorably and hence be more like to use them. Thus, the second alternative hypothesis is:

The modification process of AlSi21CuNi silumin and its effect on change of mechanical properties of the alloy

The modification process of AlSi21CuNi silumin and its effect on change of mechanical properties of the alloy

Essence of modification of silumins boils to change of form or size of silicon crystals present as eutectic or primary ones. Perfect sliding properties and high abrasion resistance of hypereutectoid silumins result from their structure, which can be characterized by precipitations of primary crystals of silicon in soft eutectic groundmass. Primary crystals of silicon are unfavorable due to their impact on machinability of material. They bring about considerable wear of tools and have negative effect on conditions of machined surface (big roughness). In case of hypereutectic silumins, by introduction of active nucleuses of crystallization are refined mainly a brittle, hard precipitations of primary silicon [1]. High content o silicon results in necessity of superheating of the alloy in limits of 850 – 900 C and keeping it

The managerial and economic effects of celebrity endorsement on consumer purchasing intentions

The managerial and economic effects of celebrity endorsement on consumer purchasing intentions

According to Ohanian (1991) the higher the perceived credibility of an endorser, the more effective the advertising tends to be. Ohanian (1991) developed a list of 139 adjectives related to source credibility, which was believed to measure celebrity endorsers’ perceived credibility. Later on, those adjectives are reduced to a more manageable list of 15 manifest variables, five for each construct: Expertise, Trustworthiness and Attractiveness. The resulting scales were submitted to a confirmatory factor analysis as well as several validity tests, from which was obtained a valid and reliable instrument. Each of these constructs has descriptive pairs to measure these variables on a 7-point bi-polar adjective scale. The descriptive pairs that measure Trustworthiness are: dependable/undependable, dishonest/honest, unreliable/reliable, insincere/sincere, and trustworthy/untrustworthy. The descriptive pairs for measuring expertise include: expert/not-expert, inexperienced / experienced, unknowledgeable/knowledgeable,
