With the adoption and popularization of internet-based platforms, sports betting has introduced new functionalities that transform the design of its products and therefore the way bettors interact with them. This study aims to explore the association between the use of new structural characteristics of online betting and gambling severity. Five characteristics are examined here: (i) live in-play betting; (ii) cash out feature use (as example of in-play betting in-built features); (iii) fantasy sports gaming; (iv) location of betting; and (v) device or platform used to make bets. A cohort (N = 659) of Spanish gamblers who had bet on sports during the previous year was recruited through an online survey. The results suggested that those bettors scoring higher on gambling problems also utilized more often such new structural characteristics, in a proportion not explained only by their higher overall gambling activity. Mobile betting was especially frequent among problem gamblers.
Environmental stimuli in the form of marketing inducements to gamble money on sports have increased in recent years. The purpose of the present paper is to tackle the extended definition of the gamblification of sport using sponsorship and partnership deals of gambling, forex trading, and fantasy gaming as a proxy for assessing its environmental impact. Using data about sponsorship deals from English Football Premier League, the paper builds on the evidence of English football’s gamblification process to discuss the impact that the volume, penetration, and marketing strategies of sports betting might have on public health and well-being. Findings demonstrate that gambling marketing has become firmly embedded in the financial practices of many Premiership football clubs. It is argued that such associations are not trivial, and that the symbolic linkage of sport and newer gambling forms can become an issue of public health, especially affecting vulnerable groups such as minors and problem gamblers. The present study is the first to explore in-depth the relationship and potential consequences and psychosocial impacts of sports-related marketing, particularly in relation to football. 相似文献
Raised levels of microalbuminuria pointing out glomerular abnormality and indicate renal damage. Glomerulonephritis is caused by immune reaction leading to the formation of circulating immune complexes that are deposited on the basal membrane of the glomerulus. The time course and the appearance of antibodies against infectious agents both play very important roles in its clinical presentation. Antibodies against streptococci have not a protective role, but offers a useful marker of the presence or absence of recent infection. This work studies the presence of microalbuminuria and circulating anti-streptococcal antibodies, namely, anti-streptolysin O and anti-deoxyribonuclease B antibodies in ninety children which underwent tonsillectomy due to infectious and obstructive tonsillar pathology. These children were divided in recurrent acute tonsillitis (n= 34), recurrent tonsillitis with tonsillar hypertrophy (n = 26), and tonsillar hypertrophy (n = 30). It was found in recurrent acute tonsillitis a moderate correlation between microalbuminuria and anti-streptolysin O, and a weak correlation between microalbuminuria and anti-deoxyribonuclease B antibodies. It was also found significant differences of the levels of anti-streptococcal antibodies between the three groups of pathologies. It is proposed the determination of microalbuminuria, an inexpensive and harmless test, as an indicator of possible renal damage in recurrent acute tonsillitis. 相似文献
Introduction: Parkinson’s disease is a progressive neurodegenerative disease that affects millions of elderly individuals worldwide. Despite intensive efforts dedicated to find a better treatment, the pathogenesis of Parkinson’s Disease remains unknown. In search for a better therapy for the disease, several new in vivo and in vitro models of Parkinson´s disease have been developed in recent times.
Areas covered: The authors provide an outline of the various traditional models of Parkinson´s disease and address those that have been recently generated. They also discuss the utility of these models for the identification of drugs of potential therapeutic value for Parkinson´s Disease patients. From the cell based models and the well-known toxin-based animal models, to the recent genetic models and the increasingly used non-mammalian models, every model is worthwhile in the search for a better Parkinson´s Disease therapy.
Expert opinion: Almost 60 years after its discovery, levodopa is still the gold standard treatment for Parkinson's Disease patients. It seems unlikely that a single model can fully recapitulate the complexity of Parkinson's Disease in the same way it appears improbable that a unique treatment could relieve both the motor and non-motor symptoms of Parkinson's Disease altogether. Therefore treatment will probably require a combination of therapies. 相似文献
The evaluation of body composition (BC) is relevant in the evaluation of children’s health-disease states. Different methods and devices are used to estimate BC. The availability of methods and the clinical condition of the patient usually defines the ideal approach to be used. In this cross-sectional study, we evaluate the accuracy of different methods to estimate BC in Mexican children and adolescents, using the 4-C model as the reference. In a sample of 288 Mexican children and adolescents, 4-C body composition assessment, skinfold-thickness (SF), dual-energy X-ray absorptiometry (DXA), air displacement plethysmography (ADP), and deuterium dilution (D2O) were performed, along with MRI in a subsample (52 participants). The analysis of validity was performed by correlation analysis, linear regression, and the Bland–Altman method. All methods analyzed showed strong correlations for FM with 4-C values and between each other; however, DXA and MRI overestimated FM, whereas skinfolds and ADP under-estimated FM. Conclusion: The clinical assessment of BC by means of SF, ADP, DXA, MRI and D2O correlated well with the 4-C model and between them, providing evidence of their clinical validity and utility. The results from different methods are not interchangeable. Preference between methods may depend on their availability and the specific clinical setting. 相似文献
Cancer is a genetic disease that is caused by mutations in oncogenes, tumor suppressor genes and stability genes. The fact that the metabolism of tumor cells is altered has been known for many years. However, the mechanisms and consequences of metabolic reprogramming have just begun to be understood. In this review, an integral view of tumor cell metabolism is presented, showing how metabolic pathways are reprogrammed to satisfy tumor cell proliferation and survival requirements. In tumor cells, glycolysis is strongly enhanced to fulfill the high ATP demands of these cells; glucose carbons are the main building blocks in fatty acid and nucleotide biosynthesis. Glutaminolysis is also increased to satisfy NADPH regeneration, whereas glutamine carbons replenish the Krebs cycle, which produces metabolites that are constantly used for macromolecular biosynthesis. A characteristic feature of the tumor microenvironment is acidosis, which results from the local increase in lactic acid production by tumor cells. This phenomenon is attributed to the carbons from glutamine and glucose, which are also used for lactic acid production. Lactic acidosis also directs the metabolic reprogramming of tumor cells and serves as an additional selective pressure. Finally, we also discuss the role of mitochondria in supporting tumor cell metabolism. 相似文献
Background Adverse drug reactions are a major public health problem. Underreporting is an important limitation of all reporting systems, partially due to attitudes of health professionals. Objective This study sought: (1) to evaluate the reproducibility of a questionnaire on attitudes to and knowledge of adverse drug reaction (ADR) reporting among physicians, nurses and pharmacists: and (2) to compare the attitudes and knowledge of these three groups of health professionals. Methods This study targeted a sample of physicians (n?=?30), nurses (n?=?30) and pharmacists (n?=?20) in the central region of Portugal. A structured questionnaire was administered to each health professional twice, at an interval of 2?C4?weeks. Most attitudes were based on Inman??s ??seven deadly sins?? and measured using a continuous visual analog scale (VAS), with answers scored from 0 (total disagreement) to 10 (total agreement). Questionnaire reproducibility was determined using the intraclass correlation coefficient (ICC). Results The response rate was 100?%. Attitudes that registered the highest ICCs were Complacency (the belief that really serious ADRs are well documented by the time a drug is marketed) (physicians, ICC 0.84; nurses, ICC 0.70; pharmacists, ICC 0.99), and Diffidence (the belief that one would only report an ADR if one were sure that it was related to the use of a particular drug) (physicians, ICC 0.73; nurses, ICC 0.65; pharmacists, ICC 0.98). In most cases, there were no differences among the three groups of professionals in terms of attitudes and knowledge. Conclusions The Horizontal continuous VAS is reliable to detect the knowledge and attitudes about ADRs. 相似文献
Perfusion-diffusion (perfusion-weighted imaging (PWI)/diffusion-weighted imaging (DWI)) mismatch is used to identify penumbra in acute stroke. However, limitations in penumbra detection with mismatch are recognized, with a lack of consensus on thresholds, quantification and validation of mismatch. We determined perfusion and diffusion thresholds from final infarct in the clinically relevant spontaneously hypertensive stroke-prone (SHRSP) rat and its normotensive control strain, Wistar-Kyoto (WKY) and compared three methods for penumbra calculation. After permanent middle cerebral artery occlusion (MCAO) (WKY n=12, SHRSP n=15), diffusion-weighted (DWI) and perfusion-weighted (PWI) images were obtained for 4 hours post stroke and final infarct determined at 24 hours on T2 scans. The PWI/DWI mismatch was calculated from volumetric assessment (perfusion deficit volume minus apparent diffusion coefficient (ADC)-defined lesion volume) or spatial assessment of mismatch area on each coronal slice. The ADC-derived lesion growth provided the third, retrospective measure of penumbra. At 1 hour after MCAO, volumetric mismatch detected smaller volumes of penumbra in both strains (SHRSP: 31±50 mm3, WKY: 22±59 mm3, mean±s.d.) compared with spatial assessment (SHRSP: 36±15 mm3, WKY: 43±43 mm3) and ADC lesion expansion (SHRSP: 41±45 mm3, WKY: 65±41 mm3), although these differences were not statistically significant. Spatial assessment appears most informative, using both diffusion and perfusion data, eliminating the influence of negative mismatch and allowing the anatomical location of penumbra to be assessed at given time points after stroke. 相似文献
The mechanism of the ototoxicity caused by cisplatin is based in the generation of reactive oxygen species, which interferes with the antioxidant protection of the organ of Corti. Conversely, the protection of the cochlea with antioxidants ameliorates the ototoxicity by cisplatin. The ototoxicity produced by cisplatin can be reversible or persistent, depending on the age of the patient, cumulative doses, number of chemotherapy cycles, history of noise exposure, and deteriorating renal function. We have obtained in rats an ototoxic chart utilizing cisplatin (10 mg/kg body weight injected intraperitoneally, once only). Together with this treatment, the animals were treated with melatonin in the drinking water (10 mg/L) or injected subcutaneously (250 microg), and with an antioxidant mixture, injected subcutaneously, composed of 0.25 mg alpha-tocopherol acid succinate, 3 mg ascorbic acid, 1 mg glutathione, and 60 mg N-acetylcysteine. The distortion product otoacoustic emissions were determined for a prolonged period of time for each animal. The ototoxicity produced by cisplatin was maximal from days 7 to 10 post-treatment, returning to normal values in a month. When melatonin and the antioxidant mixture were present, the recovery was between days 10 and 15 post-treatment, independent of the means of administration of the pineal product. We conclude that the ototoxicity caused by cisplatin is ameliorated by melatonin and other antioxidants. 相似文献
