Enhancing Foreign Language Learning Approaches to Promote Healthy Aging: A Systematic Review.

The main purpose of this study is to investigate the best approaches to teaching a foreign language to older people to help them achieve the desired results and explore their benefits. This review strictly follows the PRISMA methodology for systematic reviews and meta-analyses to identify the core experimental studies that deal with the topic of foreign language learning approaches among the older generations. Altogether eight studies detected were included in the systematic review. The available sources were found in Web of Science and Scopus. The findings indicate that foreign language learning can promote seniors' welfare and successful aging despite their learning outcomes, which means that the key benefit for third-age foreign language learners while learning a foreign language is not the achieved proficiency level, but the feeling of subjective satisfaction. This can be a good incentive to achieve better learning outcomes, provided that learners have been offered a pleasant and safe learning environment, using suitable learning approaches during which they can build on their acquired knowledge and experience, as well as discuss the topics they are interested in. Thus, foreign language teachers play an important part in seniors' educational process because their teaching methods and materials when adapted to the elderly's educational needs can have a positive impact on the maintenance and possibly, enhancement of the older people's cognitive functions and on the improvement of their mental activity, which consequently maintains their healthy aging.

Interferon Beta-1a versus Glatiramer Acetate: Changes of Innate Immunity in a Group of Women with Multiple Sclerosis.

INTRODUCTION: Multiple sclerosis (MS) is a chronic inflammatory autoimmune demyelinating disease that secondarily leads to axonal loss and associated brain atrophy. Disease-modifying drugs (DMDs) have previously been studied for their ability to affect specific immunity. This study investigates the effect of interferon beta-1a (INF) and glatiramer acetate (GA) administration on changes in innate immunity cell populations. METHODS: Sixty Caucasian female patients with relapsing-remitting MS undergo blood sample testing for 15 blood parameters at baseline, 1 month, 3 months, and 6 months after treatment by GA or IFN (started as their first-line DMD). RESULTS: A statistically significant difference in the change after 6 months was found in the parameter monocytes (relative count) in the group of patients treated with IFN. The median increase was 27.8%. Changes in many of the other 15 parameters studied were 10-20%. CONCLUSION: Innate immunity has long been neglected in MS immunopathology. The findings suggest that IFN treatment may modulate the immune response in MS by affecting monocyte function and may provide insight into the mechanisms of action of IFN in MS.

Neuropharmacology of Cevimeline and Muscarinic Drugs-Focus on Cognition and Neurodegeneration.

At present, Alzheimer's disease (AD) and related dementias cannot be cured. Therefore, scientists all over the world are trying to find a new approach to prolong an active life of patients with initial dementia. Both pharmacological and non-pharmacological pathways are investigated to improve the key symptom of the disease, memory loss. In this respect, influencing the neuromodulator acetylcholine via muscarinic receptors, such as cevimeline, might be one of the therapeutic alternatives. The purpose of this study is to explore the potential of cevimeline on the cognitive functions of AD patients. The methodology is based on a systematic literature review of available studies found in Web of Science, PubMed, Springer, and Scopus on the research topic. The findings indicate that cevimeline has shown an improvement in experimentally induced cognitive deficits in animal models. Furthermore, it has demonstrated to positively influence tau pathology and reduce the levels of amyloid-ß (Aß) peptide in the cerebral spinal fluid of Alzheimer's patients. Although this drug has not been approved by the FDA for its use among AD patients and there is a lack of clinical studies confirming and extending this finding, cevimeline might represent a breakthrough in the treatment of AD.

Psychosocial Rehabilitation Through Intervention by Second Language Acquisition in Older Adults.

The paper deals with a possibility of foreign language learning (FLL) intervention in older adults as a psychosocial rehabilitation method to improve the quality of life (QoL) in this age segment, i.e. the people who are over 55 years. FLL has been researched as a successful tool to maintain or even enhance cognitive functions in older age along with other intentional activities, such as engagement in any physical activity. FLL cannot dramatically improve memory and cognitive deterioration of older adults, however, it can improve QoL by increasing subjective happiness that is connected to improved wellbeing. The research was conducted in two groups of seniors who are engaged in FLL, specifically in the Czech Republic and Poland. The major premise of the research was based on the positive psychology concept, i.e., the subjective happiness leads to improved levels of QoL. Both groups consisted of about a hundred respondents whose opinions were researched by an online questionnaire. The major focus of this questionnaire was to evaluate the level of subjective happiness and then compare the results obtained from the respondents from these two geographically different regions. The findings clearly showed that those who had engaged in FLL had reached high levels of subjective happiness, therefore, their subjective wellbeing could be improved. These results might be important for psychosocial rehabilitation practices because they can create a framework for further non-pharmacological intervention to maintain healthy aging. FLL can thus be a very efficient tool for any psychosocial rehabilitation in older healthy adults who do not suffer from any cognitive pathological development but who are just experiencing negative side effects of natural aging process. The research into this topic is very scarce, and therefore, this paper could be an inspiration for further and larger-scale research.

Comparison of Pulsed Radiofrequency, Oxygen-Ozone Therapy and Epidural Steroid Injections for the Treatment of Chronic Unilateral Radicular Syndrome.

Background and objectives: For the treatment of chronic unilateral radicular syndrome, there are various methods including three minimally invasive computed tomography (CT)-guided methods, namely, pulsed radiofrequency (PRF), transforaminal oxygen ozone therapy (TFOOT), and transforaminal epidural steroid injection (TFESI). Despite this, it is still unclear which of these methods is the best in terms of pain reduction and disability improvement. Therefore, the purpose of this study was to evaluate the short and long-term effectiveness of these methods by measuring pain relief using the visual analogue scale (VAS) and improvement in disability (per the Oswestry disability index (ODI)) in patients with chronic unilateral radicular syndrome at L5 or S1 that do not respond to conservative treatment. Materials and Methods: After screening 692 patients, we enrolled 178 subjects, each of whom underwent one of the above CT-guided procedures. The PRF settings were as follows: pulse width = 20 ms, f = 2 Hz, U = 45 V, Z ˂ 500 Ω, and interval = 2 × 120 s. For TFOOT, an injection of 4-5 mL of an O2-O3 mixture (24 µg/mL) was administered. For the TFESI, 1 mL of a corticosteroid (betamethasone dipropionate), 3 mL of an anaesthetic (bupivacaine hydrochloride), and a 0.5 mL mixture of a non-ionic contrast agent (Iomeron 300) were administered. Pain intensity was assessed with a questionnaire. Results: The data from 178 patients (PRF, n = 57; TFOOT, n = 69; TFESI, n = 52) who submitted correctly completed questionnaires in the third month of the follow-up period were used for statistical analysis. The median pre-treatment visual analogue scale (VAS) score in all groups was six points. Immediately after treatment, the largest decrease in the median VAS score was observed in the TFESI group, with a score of 3.5 points (a decrease of 41.7%). In the PRF and TFOOT groups, the median VAS score decreased to 4 and 5 points (decreases of 33% and 16.7%, respectively). The difference in the early (immediately after) post-treatment VAS score between the TFESI and TFOOT groups was statistically significant (p = 0.0152). At the third and sixth months after treatment, the median VAS score was five points in all groups, without a statistically significant difference (p > 0.05). Additionally, there were no significant differences in the Oswestry disability index (ODI) values among the groups at any of the follow-up visits. Finally, there were no significant effects of age or body mass index (BMI) on both treatment outcomes (maximum absolute value of Spearman's rank correlation coefficient = 0.193). Conclusions: Although the three methods are equally efficient in reducing pain over the entire follow-up, we observed that TFESI (a corticosteroid with a local anaesthetic) proved to be the most effective method for early post-treatment pain relief.

Highly active RRMS and ocrelizumab after failure of alemtuzumab therapy.

BACKGROUND: A high multiple sclerosis activity while on alemtuzumab is rather uncommon compared to moderate-efficacy drugs. The purpose of this case report is to present a case of a 37-year-old female patient with bronchial asthma and no other medical history, whose disease activity required switching from dimethyl fumarate to fingolimod, then to alemtuzumab and finally to ocrelizumab. CASE PRESENTATION: In our patient, two severe attacks were observed and treated after administration of the first pulse of alemtuzumab. After six months of therapy, patient's immunological profile showed the expected decrease in CD4+ and CD8+ T-cells and, markedly increased values of CD19+ B-cells. Surprisingly memory B-cells, which typically repopulate very slowly following alemtuzumab treatment, were above baseline levels. Regular administration of ocrelizumab based on a standardised scheme, after the alemtuzumab therapy failure, resulted in the stabilisation of the patient's condition both clinically and radiologically. CONCLUSION: Thus, when the alemtuzumab treatment is unsuccessful, the authors recommend testing T- and B-cell levels and proceeding with an early switch to ocrelizumab if high B-cell counts are found.

Flakka: New Dangerous Synthetic Cathinone on the Drug Scene.

New psychoactive substances are being used as drugs and appear to be quite popular nowadays. Thanks to their specific properties, these drugs create inimitable experiences for intoxicated people. Synthetic cathinones are the most common compounds in these new drugs. Among them, α-pyrrolidopentadione (α-PVP), or "Flakka" (street name), is one of the most famous cathinone-designed drugs. Similar to other synthetic cathinone drugs, α-PVP can effectively inhibit norepinephrine and dopamine transmitters. The adverse reactions of α-PVP mainly include mania, tachycardia, and hallucinations. An increasing number of people are being admitted to emergency wards due to the consequences of their use. This work mainly summarizes the history, synthesis, pharmacology, toxicology, structure-activity relationship, metabolism, clinical process and health risks, poisoning and death, forensic toxicology, and legal status of α-PVP. We hope this review will help bring more attention to the exploration of this substance in order to raise awareness of its negative impacts on humans.

Medical tourism: its research and implications for public health.

OBJECTIVE: The purpose of this article is to describe current research trends in medical tourism and implications for public health, especially in destination countries. METHODS: The methods used for this article include a literature review of available sources on the research topic in the world's acknowledged databases Web of Science, Scopus, MEDLINE, and ScienceDirect. RESULTS: The findings indicate that there is no consensus on the definition of medical tourism. However, there are a few conceptual models which can be used in further medical tourism research and practice. The findings also reveal that there are still certain issues, which hinder the fast growth of medical tourism, such as unclear impact on healthcare systems, ethical concerns or a lack of effective tools for the measurement of quality assurance of the medical tourism services and their products. CONCLUSIONS: There is a need for data collection on medical tourism, both at national and worldwide level to provide a realistic picture of this evolving field of tourism as well as implications for public health in destination countries.

Effectiveness of the dog therapy for patients with dementia - a systematic review.

BACKGROUND: Dementia represents a mental and economic burden for both patients and their caregivers. Therefore, the aim of this study is to explore the effectiveness of animal assisted therapy (AAT) with special focus on canis therapy among people with dementia, specifically Alzheimer's disease. METHODS: The key method of this review study is a systematic review of the research studies detected in the Web of Science, Scopus and PubMed. The search was conducted for the studies dating from 2016 till 31 August 2018 because several review studies were published before. Eventually, only six studies were involved into the final analysis. RESULTS: The findings of this review, based on significant effect sizes, reveal that AAT may work as a beneficial and effective complementary treatment, especially in the area of behavioral and psychological symptoms, for patients with different degree of dementia severity if AAT is targeted at their specific needs and interests. CONCLUSIONS: More research in the area of methodology for the implementation of AAT is necessary, and more research should be conducted with respect to the use of AAT for the improvement of cognitive functions in people with dementia.

E-learning as valuable caregivers' support for people with dementia - A systematic review.

BACKGROUND: Present demographic trends show a considerable rise in elderly populations with aging disorders, such as dementia. The current article focused on the exploitation of e-learning as an informal support for caregivers of people with dementia and considered its benefits and limitations to provide proper and relevant care for this target group of people as well as maintain the quality of life of their caregivers. METHODS: The methodology of this study is based on a literature review of accessible peer-review articles from three recognized databases: Web of Science, Scopus, and PubMed. The findings of the selected studies were compared and evaluated. RESULTS: The findings showed that e-learning educational programs/courses helped caregivers feel more confident about dementia care, reduced their perceived stress and enhanced their feelings of empathy, understanding and concern. CONCLUSIONS: The findings of this study reveal that the exploitation of e-learning as a support tool, especially for informal caregivers, in the management of dementia may be a promising method, but its implementation requires professional training of informal caregivers in the use of this technology. More evidence-based studies are needed on this topic.

Impact of Learning a Foreign Language on the Enhancement of Cognitive Functions Among Healthy Older Population.

The purpose of this article is to discuss to what extent foreign language learning may enhance cognitive functions among healthy older population. The methods used in this study included cognitive assessments using standardized tests, intervention through English language teaching and learning, and statistical analysis. Out of 60 older Czech citizens, 42 cognitively unimpaired participants were selected for the experiment. These participants were randomly divided into an experimental group (20 subjects) studying English for 12 weeks (three 45-min lessons per week) and a control group (22 subjects) whose members did not have any language training. The results of the research show that there has been a slight enhancement of cognitive skills in the experimental group. Nevertheless, on the whole, the scores of the experimental and control groups did not considerably differ. Despite this fact, the results indicate that cognitive functions among healthy older population can be maintained through regular foreign language training.

Selected rare paediatric communication neurological disorders.

The purpose of this review is to discuss rare neurological disorders with respect to communication difficulties typical of children. Firstly, communication disorders with special focus on rare communication neurological disorders are discussed. Secondly, on the basis of literature review, the authors explore clinical studies on the most typical rare children's communication neurological disorders. Thirdly, on the basis of the findings from the clinical studies, they set a few recommendations for their medical therapies and management. The methodology was based on the literature review of research studies exploring the research issue. The findings show that the intervention strategies appear to have positive effects on the improvement of speech and language production among children suffering from Landau-Kleffner syndrome and childhood apraxia of speech. Nevertheless, randomized control trials are needed in order to accelerate and facilitate an early and relevant diagnosis and treatment management. In addition, a multidisciplinary approach seems to be the most appropriate for the accurate diagnosis and comprehensive treatment.

Mobile Learning in Medical Education.

Currently, mobile learning is a new trend in medical education. Therefore, the aim of this study is to examine the use of m-learning in medical education and discuss its effect on student learning process in order to help future medical professionals deliver better care for patients and populations. This was done by conducting a literature search in the databases Web of Science, Scopus, and MEDLINE, and consequently by evaluating the findings of the selected studies. The results of this study confirm that mobile learning is efficient, especially in the acquisition of new knowledge and skills. Nevertheless, so far, the role of mobile learning has been perceived as an appropriate complement to traditional learning. Therefore, more research should be conducted on the efficacy of the use mobile learning in medical education, as well as to explore the unique features of mobile devices for the enhancement of learning outcomes.

Lymphocyte populations and their change during five-year glatiramer acetate treatment.

BACKGROUND: The goal of this study was to determine the characteristics that are affected in patients treated with glatiramer acetate (GA). METHODS: A total of 113 patients were included in this study. Patients were treated with glatiramer acetate (subcutaneous injection, 20 mg, each day). Peripheral blood samples were obtained just prior to treatment as well as 5 years after GA treatment. All the calculations were performed with the statistical system R (r-project.org). RESULTS: After 5 years of treatment, a significant decrease was found in the absolute and relative CD3+/CD69+ counts, the absolute and relative CD69 counts, the relative CD8+/CD38+ count and the relative CD38 count. A significant increase was found in the absolute and relative CD5+/CD45RA+ counts and the absolute CD5+/CD45RO+ count after 5 years of treatment. CONCLUSION: This study presents some parameters that were affected by long-term GA treatment.

Potential of mobile technologies and applications in the detection of mild cognitive impairment among older generation groups.

At present, demographic changes result in the growing number of older people. This trend inevitably brings about serious social and economic issues, as well as occurrence of aging diseases. The purpose of this study is to discuss the potential of using mobile technologies and applications in the detection of aging disorders such as mild cognitive impairment. The methods used for this review study include a literature search in the world's acknowledged databases. The findings of this study indicate that mobile applications can serve as appropriate diagnostic tools for aging disorders such as mild cognitive impairment because they seem to provide better, faster, and less costly care for older people.

Application of salutogenic concept in social work with diabetic patients.

In the context of salutogenesis, coping with diabetes is perceived as a dynamic process of changes in all aspects of biopsychosocial model of health/disease. Understanding of salutoprotective factors allows for estimation of client's extent of vulnerability and ability to cope with the disease. The objective of the study is to assess selected salutoprotective factors in diabetic clients (SOC-type hardiness, well-being-subjective feelings and states scale [SUPOS], perceived social support scale [PSSS]). Low values of SOC, PSSS, and SUPOS suggest an increased need in psychosocial care. The possibility to strengthen an individual's hardiness and to influence perceived social support adverts to the irreplaceable role of social workers at counseling and educational levels as well as that of a form of social support.

Mobile applications as good intervention tools for individuals with depression.

At present mental disorders affect approximately 450 million people around the world. Depressive disorder is probably one of the most serious disorders and as a type of chronic disease, it represents a global threat and burdens economic and social systems of both individuals and governments worldwide. One of these most recent non-pharmacological approaches is also the so-called mHealth (mobile health), the use of mobile devices for the practice of medicine and public health, which proves to be effective particularly in the early stages of depression. The purpose of this article is to explore the most recent randomized controlled trial studies which indicate efficacy of the use of mobile applications in the detection, diagnostics or treatment of depression. The methods used in this study include a method of literature search of the studies focused on the impacts of individual applications for people with depression and on the specification of criteria evaluating quality of these applications. The findings of the randomized controlled trials (RCT) show that there is a big potential of mobile applications in the detection, diagnostics, and treatment of depression, particularly in mild and moderate stages of the disease. They seem to be especially relevant for self-monitoring of depressive symptoms in the early stages of depression. There is an urgent need of more longitudinal RCT in this field in order to prove conclusive efficacy of these mobile applications in the treatment of depression. The authors list the main strengths and weaknesses of mobile applications in the detection, diagnostics, and treatment of depression.Key words: mobile applications depression treatment.

Medical and non-medical costs of Parkinson disease - comparison of Europe, USA, Asia an Australia.

At present different kinds of dementia impose a significant economic burden on the whole societies. Parkinsons disease is the second most common type of dementia. The purpose of this study is to analyze the costs of people suffering from Parkinsons disease in the context of public expenditure needs for the affected people. Firstly, the treatment costs and care in the selected European countries are analyzed, and secondly, these data are compared with the data from other countries and continents. The focus is not only on the developed economies where the issue of costs and PD already causes significant expenditure from public budgets, but also on the developing economies. The methods applied in this study include a method of literature search of available sources describing the costs of PD and a qualitative comparative analysis method. The findings show that the data from the European countries range between 1,949 € and 12,054 €. Comparable data are in the USA at 17,064 €, in Australia at 7,020 € and in Asia they range between 649 € and 9,544 €. These values are certainly connected not only with the available data, but also with the level and possibilities of healthcare services in these countries. In addition, GDP for these continents and countries was specified and the cost ratio of patient with respect to GHD per capita was described. This calculation provides an orientation relative indicator about the economic burden with respect to the countrys development. The results indicate that the most significant issues are diseases and treatment in the European countries in which their highest incidence is expected in future.Key words: Parkinsons disease costs health care analysis.

The antioxidant, immunomodulatory, and anti-inflammatory activities of Spirulina: an overview.

Spirulina is a species of filamentous cyanobacteria that has long been used as a food supplement. In particular, Spirulina platensis and Spirulina maxima are the most important. Thanks to a high protein and vitamin content, Spirulina is used as a nutraceutical food supplement, although its other potential health benefits have attracted much attention. Oxidative stress and dysfunctional immunity cause many diseases in humans, including atherosclerosis, cardiac hypertrophy, heart failure, and hypertension. Thus, the antioxidant, immunomodulatory, and anti-inflammatory activities of these microalgae may play an important role in human health. Here, we discuss the antioxidant, immunomodulatory, and anti-inflammatory activities of Spirulina in both animals and humans, along with the underlying mechanisms. In addition, its commercial and regulatory status in different countries is discussed as well. Spirulina activates cellular antioxidant enzymes, inhibits lipid peroxidation and DNA damage, scavenges free radicals, and increases the activity of superoxide dismutase and catalase. Notably, there appears to be a threshold level above which Spirulina will taper off the antioxidant activity. Clinical trials show that Spirulina prevents skeletal muscle damage under conditions of exercise-induced oxidative stress and can stimulate the production of antibodies and up- or downregulate the expression of cytokine-encoding genes to induce immunomodulatory and anti-inflammatory responses. The molecular mechanism(s) by which Spirulina induces these activities is unclear, but phycocyanin and ß-carotene are important molecules. Moreover, Spirulina effectively regulates the ERK1/2, JNK, p38, and IκB pathways. This review provides new insight into the potential therapeutic applications of Spirulina and may provide new ideas for future studies.

Alzheimers disease: cost cuts call for novel drugs development and national strategy.

Mental health affects the quality of life for a large number of individuals and family members. Currently, globally costs for people with dementia amount to more than 1% of gross domestic product (GDP). In the future, the growth of expenditure is expected with regard to the fact that the population of developed countries is aging and the dementia is closely associated with increasing age. It is evident that governments have to allocate adequate financial, material and human resources to address a health problem on this scale. The purpose of this article is to explore the current state of treatment and care of patients suffering from Alzheimers disease (AD), analyze direct and indirect health care costs resulting from this disease. In addition, the authors of this article draw attention to the implementation of astrategic plan which would handle all the aspects of AD, including the research of drugs development since nowadays there are not still many drugs which would improve AD patients state, particularly in the early phases, as well as there does not exist any well-functioning national strategic plan in the Czech Republic which would bring a radical improvement in reducing the effects of AD.Key words: Alzheimers disease costs treatment strategic plan.
