A comparison of extrinsic and intrinsic motivators between Germany and South Africa

This thesis explored different perceptions of extrinsic and intrinsic motivation in an intercultural context. The main objective of this study was to investigate similarities and differences concerning extrinsic and intrinsic motivation in the workplace between the German and the South African culture by examining individuals with working experience and tertiary education. It provides background information about motivation and a historical overview of previous and current motivational theories as well as cultural influences and differences. In addition, regarding the two cultures the researcher aimed to investigate similarities and differences between other demographics such as gender, age and income. The literature review provides information about extrinsic and intrinsic motivation retrieved from previous research and puts it into an intercultural context. The researcher conducted a quantitative, exploratory study. The data was gathered using an existing research instrument, which was distributed online. The sample comprised 374 respondents. This sample was conducted by a combination of quota and snowball sampling. The obtained data is evaluated and presented in text and table form. The results revealed preferences for intrinsic motivators for the whole sample and higher motivation for the South African part of the sample. Demographic characteristics played a minor role

Immune modulation and increased neurotrophic factor production in multiple sclerosis patients treated with testosterone

<p>Abstract</p> <p>Background</p> <p>Multiple sclerosis is a chronic inflammatory disease of the central nervous system with a pronounced neurodegenerative component. It has been suggested that novel treatment options are needed that target both aspects of the disease. Evidence from basic and clinical studies suggests that testosterone has an immunomodulatory as well as a potential neuroprotective effect that could be beneficial in MS.</p> <p>Methods</p> <p>Ten male MS patients were treated with 10 g of gel containing 100 mg of testosterone in a cross-over design (6 month observation period followed by 12 months of treatment). Blood samples were obtained at three-month intervals during the observation and the treatment period. Isolated blood peripheral mononuclear cells (PBMCs) were used to examine lymphocyte subpopulation composition by flow cytometry and <it>ex vivo </it>protein production of cytokines (IL-2, IFNγ, TNFα, IL-17, IL-10, IL-12p40, TGFβ1) and growth factors (brain-derived neurotrophic factor BDNF, platelet-derived growth factor PDGF-BB, nerve growth factor NGF, and ciliary neurotrophic factor CNTF). Delayed type hypersensitivity (DTH) skin recall tests were obtained before and during treatment as an <it>in vivo </it>functional immune measure.</p> <p>Results</p> <p>Testosterone treatment significantly reduced DTH recall responses and induced a shift in peripheral lymphocyte composition by decreasing CD4+ T cell percentage and increasing NK cells. In addition, PBMC production of IL-2 was significantly decreased while TGFβ1 production was increased. Furthermore, PBMCs obtained during the treatment period produced significantly more BDNF and PDGF-BB.</p> <p>Conclusion</p> <p>These results are consistent with an immunomodulatory effect of testosterone treatment in MS. In addition, increased production of BDNF and PDGF-BB suggests a potential neuroprotective effect.</p> <p>Trial Registration</p> <p>NCT00405353 <url>http://www.clinicaltrials.gov</url></p

Treatment of progressive multiple sclerosis: what works, what does not, and what is needed.

Disease-modifying drugs have mostly failed as treatments for progressive multiple sclerosis. Management of the disease therefore solely aims to minimise symptoms and, if possible, improve function. The degree to which this approach is based on empirical data derived from studies of progressive disease or whether treatment decisions are based on what is known about relapsing-remitting disease remains unclear. Symptoms rated as important by patients with multiple sclerosis include balance and mobility impairments, weakness, reduced cardiovascular fitness, ataxia, fatigue, bladder dysfunction, spasticity, pain, cognitive deficits, depression, and pseudobulbar affect; a comprehensive literature search shows a notable paucity of studies devoted solely to these symptoms in progressive multiple sclerosis, which translates to few proven therapeutic options in the clinic. A new strategy that can be used in future rehabilitation trials is therefore needed, with the adoption of approaches that look beyond single interventions to concurrent, potentially synergistic, treatments that maximise what remains of neural plasticity in patients with progressive multiple sclerosis

Lifestyle intervention improves cognition and quality of life in persons with early Multiple Sclerosis

BackgroundLifestyle changes have been demonstrated to impact pathophysiology in Multiple Sclerosis (MS). Various diet and exercise protocols have been reported to improve symptoms and function in persons with MS. Evidence is accumulating that interventions as early as possible in the disease course are warranted. The objective of this study was to investigate the effect of a remotely delivered lifestyle program focusing on specific diet and exercise recommendations in persons with early MS.MethodsMS patients, with disease diagnosis no more than 2 years prior, were recruited from the patient population of the MS clinic of the Pacific Neuroscience Institute. Participants followed recommendations for diet and exercise delivered via remote heath coaching. Each participant received 6 sessions with a health coach over a 12-week period. They were given parameters of a Mediterranean-type diet to follow, and specific and individualized recommendations about duration, intensity and type of exercise and physical activity. Outcome measures included Quality of Life (QOL), cognition (Symbol Digit Modalities Test, SDMT), fatigue (Multiple Sclerosis Fatigue Impact Scale, MFIS), fitness (estimated with Metabolic equivalents, METS) and other objective and patient reported outcomes (PRO). Changes in outcomes were analyzed using mixed effects general linear models and standardized pre-post differences.(Cohen's d) RESULTS: Fifteen persons with early (≤ 2 years) MS enrolled in the study, 14 of whom completed the study. We observed significant improvements in QOL (p = 0.02), SDMT (p = 0.006), fatigue(p = 0.005), fitness (p = 0.04), and other PRO and objective metrics at the end of the protocol compared to baseline. Adherence and patient satisfaction measures were high.ConclusionsSpecific and individualized lifestyle recommendations can be effectively delivered remotely, and may produce improvement in symptoms and function in persons with early MS. Larger controlled trials of these interventions are warranted

Evaluating the Impact of Retinal Vessel Segmentation Metrics on Retest Reliability in a Clinical Setting: A Comparative Analysis Using AutoMorph

Purpose: Current research on artificial intelligence-based fundus photography biomarkers has demonstrated inconsistent results. Consequently, we aimed to evaluate and predict the test-retest reliability of retinal parameters extracted from fundus photography. Methods: Two groups of patients were recruited for the study: an intervisit group (n = 28) to assess retest reliability over a period of 1 to 14 days and an intravisit group (n = 44) to evaluate retest reliability within a single session. Using AutoMorph, we generated test and retest vessel segmentation maps; measured segmentation map agreement via accuracy, sensitivity, F1 score and Jaccard index; and calculated 76 metrics from each fundus image. The retest reliability of each metric was analyzed in terms of the Spearman correlation coefficient, intraclass correlation coefficient (ICC), and relative percentage change. A linear model with the input variables contrast-to-noise-ratio and fractal dimension, chosen by a P-value-based backward selection process, was developed to predict the median percentage difference on retest per image based on image-quality metrics. This model was trained on the intravisit dataset and validated using the intervisit dataset. Results: In the intervisit group, retest reliability varied between Spearman correlation coefficients of 0.34 and 0.99, ICC values of 0.31 to 0.99, and mean absolute percentage differences of 0.96% to 223.67%. Similarly, in the intravisit group, the retest reliability ranged from Spearman correlation coefficients of 0.55 and 0.96, ICC values of 0.40 to 0.97, and mean percentage differences of 0.49% to 371.23%. Segmentation map accuracy between test and retest never dropped below 97%; the mean F1 scores were 0.85 for the intravisit dataset and 0.82 for the intervisit dataset. The best retest was achieved with disc-width regarding the Spearman correlation coefficient in both datasets. In terms of the Spearman correlation coefficient, the worst retests of the intervisit and intravisit groups were tortuosity density and artery tortuosity density, respectively. The intravisit group exhibited better retest reliability than the intervisit group (P < 0.001). Our linear model, with the two independent variables contrast-to-noise ratio and fractal dimension predicted the median retest reliability per image on its validation dataset, the intervisit group, with an R2 of 0.53 (P < 0.001). Conclusions: Our findings highlight a considerable volatility in the reliability of some retinal biomarkers. Improving retest could allow disease progression modeling in smaller datasets or an individualized treatment approach. Image quality is moderately predictive of retest reliability, and further work is warranted to understand the reasons behind our observations better and thus ensure consistent retest results

Research interrupted: The impact of the COVID-19 pandemic on multiple sclerosis research in the field of rehabilitation and quality of life

Background The COVID-19 pandemic has likely had a negative impact on rehabilitation and quality of life (QoL) research in multiple sclerosis (MS). Method We explored perceived barriers to research among 87 researchers, representing 18 countries, both prior to and since COVID-19. Results A Wilcoxon signed-rank test found that significantly more researchers reported experiencing barriers to research since the onset of the pandemic compared to pre-COVID-19 (p &lt; .001), with 78% of respondents reporting at least some barriers since COVID-19. The most commonly-cited barriers related to participant access (n = 38) and interruptions/delays to projects (n = 19). Although no gender differences were found in the number of barriers reported, female respondents were more likely to cite time or competing demands as barriers to research. Females were also more likely to perceive being negatively impacted by the pandemic compared to other genders (p = .007). Conclusions Implications for the future landscape of rehabilitation research in MS are discussed. </jats:sec
