Challenging 'normalcy': possibilities and pitfalls of Paralympic bodies

The Paralympic Games is celebrated in the mainstream media in line with the vision of the International Paralympic Committee (IPC) 'To enable Paralympic athletes to achieve sporting excellence and inspire and excite the world.' In this paper we explore the degree to which the flagship of parasport has acted as a catalyst for an enhanced social and cultural understanding of disabled embodiments. Drawing upon a Foucauldian conceptualisation of biopower in connection with Harraway's articulation of the cyborg, we highlight how hybrid bodies inevitably fail to promote embodied difference because they constitute, in and of themselves, a product of "normalizing" technology. In light of critiques such as that of the sporting supercrip, we argue that the heroic glorification of Paralympic cyborgs further amplifies the inadequacy of non- cyborg disabled bodies, whose impairments cannot be "compensated for" by movement technologies. Ultimately, this paper is a call to reflect upon how parasport culture can enhance its ability to deliver the empowerment ideal encapsulated within its vision

The fiddle of using the Paralympic Games as a vehicle for expanding [dis]ability sport participation

In this paper we highlight the need to explore the excessive significance given to the Paralympic Games as a vehicle for the encouragement of participation of people with a disability within sport. The media spectacle around the games that the International Paralympic Committee (IPC) has worked tirelessly to develop has become, for policy makers and the public alike, a sufficient outlet for disability sport provision. We argue that the honourable goals of the IPC articulated through the ethos of Paralympism have been assumed to be valid for all people with a disability, yet in terms of widening participation, their utility is limited, as the Paralympics themselves are exclusionary. This paper first illuminates the relationship between the International Olympic Committee (IOC) and the IPC before we turn our attention to the ethos of Paralympism. Highlighting the necessity for 'sport for all' we show how a human rights lens, aided by a capabilities approach can facilitate better ways to educate the public about the need for equality of access to sporting participation opportunities

The social empowerment of difference: the potential influence of Para sport

In this paper, we explore the significance of parasport in highlighting an emancipatory understanding of difference and enhancing social empowerment. By illuminating the influence of ableist ideology upon people with impairments we draw upon the field of disability studies. We ultimately argue that rather than being supressed, difference should be recognised and valued in parasport practices and ideologies, leading to a pluralist culture, in which further and wider social emancipation can be grounded. Acceptance of difference is an absolute and essential pre-condition for parasport cultures to promote positive social change for people with disabilities

The mental health of elite athletes: A narrative systematic review

BACKGROUND: The physical impacts of elite sport participation have been well documented; however, there is comparatively less research on the mental health and psychological wellbeing of elite athletes. OBJECTIVE: This review appraises the evidence base regarding the mental health and wellbeing of elite-level athletes, including the incidence and/or nature of mental ill-health and substance use. METHODS: A systematic search of the PubMed, EMBASE, SPORTDiscus, PsycINFO, Cochrane and Google Scholar databases, up to and including May 2015, was conducted. RESULTS: The search yielded a total of 2279 records. Following double screening, 60 studies were included. The findings suggested that elite athletes experience a broadly comparable risk of high-prevalence mental disorders (i.e. anxiety, depression) relative to the general population. Evidence regarding other mental health domains (i.e. eating disorders, substance use, stress and coping) is less consistent. These results are prefaced, however, by the outcome of the quality assessment of the included studies, which demonstrated that relatively few studies (25 %) were well reported or methodologically rigorous. Furthermore, there is a lack of intervention-based research on this topic. CONCLUSION: The evidence base regarding the mental health and wellbeing of elite athletes is limited by a paucity of high-quality, systematic studies. Nonetheless, the research demonstrates that this population is vulnerable to a range of mental health problems (including substance misuse), which may be related to both sporting factors (e.g. injury, overtraining and burnout) and non-sporting factors. More high-quality epidemiological and intervention studies are needed to inform optimal strategies to identify and respond to player mental health needs

Community intervention for cardiovascular disease risk factors in Kalutara, Sri Lanka.

BACKGROUND:The effectiveness of a 2015-17 community intervention to reduce cardiovascular disease (CVD) and type 2 diabetes (T2DM) risk factors is assessed in a Sri Lanka adult population, using a before-and-after study design. METHODS:Four contiguous Public Health Midwife (PHM) areas in Kalutara district (Western Province) were exposed to a Sri Lankan designed community health promotion initiatives (without screening) to lower CVD and T2DM risk factors. Pre- and post-intervention surveys (2014, n=1,019; 2017, n=908) were of 25-64 year males (M) and females (F) from dissimilar randomly selected clusters (villages or settlements) from PHMs, with probability of selection proportional to population size, followed by household sampling, then individual selection to yield equal-probability samples. Differences in resting blood pressure (BP), fasting plasma glucose (FPG), total cholesterol, body mass index and tobacco smoking, adjusting for cluster sampling, age and socio-economic differences, were examined. RESULTS:Hypertension prevalence declined from 25% to 16% (F) (p<.0001), and 21% to 17% (M). Both mean systolic and diastolic BP declined. T2DM declined from 18% to 13% (F), and 18% to 15% (M), as did mean fasting plasma glucose. Elevated total cholesterol declined from 21% to 15% in women (p=0.003) and mean cholesterol declined. Frequency distributions, medians and means of these continuous CVD risk factors shifted to lower levels, and were mostly statistically significant (p< 0.05). CONCLUSIONS:Community health promotion can lower key CVD and T2DM risk factors. Lowering tobacco consumption in males and obesity remain challenges in Sri Lanka

Relationship between cardiac diffusion tensor imaging parameters and anthropometrics in healthy volunteers

Background: In vivo cardiac diffusion tensor imaging (cDTI) is uniquely capable of interrogating laminar myocardial dynamics non-invasively. A comprehensive dataset of quantative parameters and comparison with subject anthropometrics is required. Methods: cDTI was performed at 3T with a diffusion weighted STEAM sequence. Data was acquired from the mid left ventricle in 43 subjects during the systolic and diastolic pauses. Global and regional values were determined for fractional anisotropy (FA), mean diffusivity (MD), helix angle gradient (HAg, degrees/%depth) and the secondary eigenvector angulation (E2A). Regression analysis was performed between global values and subject anthropometrics. Results: All cDTI parameters displayed regional heterogeneity. The RR interval had a significant, but clinically small effect on systolic values for FA, HAg and E2A. Male sex and increasing left ventricular end diastolic volume were associated with increased systolic HAg. Diastolic HAg and systolic E2A were both directly related to left ventricular mass and body surface area. There was an inverse relationship between E2A mobility and both age and ejection fraction. Conclusions: Future interpretations of quantitative cDTI data should take into account anthropometric variations observed with patient age, body surface area and left ventricular measurements. Further work determining the impact of technical factors such as strain and SNR is required

Tissue Localization and Extracellular Matrix Degradation by PI, PII and PIII Snake Venom Metalloproteinases: Clues on the Mechanisms of Venom-Induced Hemorrhage

20 páginas, 4 figuras, 3 tablas y 7 tablas en material suplementario.Snake venom hemorrhagic metalloproteinases (SVMPs) of the PI, PII and PIII classes were compared in terms of tissue localization and their ability to hydrolyze basement membrane components in vivo, as well as by a proteomics analysis of exudates collected in tissue injected with these enzymes. Immunohistochemical analyses of co-localization of these SVMPs with type IV collagen revealed that PII and PIII enzymes co-localized with type IV collagen in capillaries, arterioles and post-capillary venules to a higher extent than PI SVMP, which showed a more widespread distribution in the tissue. The patterns of hydrolysis by these three SVMPs of laminin, type VI collagen and nidogen in vivo greatly differ, whereas the three enzymes showed a similar pattern of degradation of type IV collagen, supporting the concept that hydrolysis of this component is critical for the destabilization of microvessel structure leading to hemorrhage. Proteomic analysis of wound exudate revealed similarities and differences between the action of the three SVMPs. Higher extent of proteolysis was observed for the PI enzyme regarding several extracellular matrix components and fibrinogen, whereas exudates from mice injected with PII and PIII SVMPs had higher amounts of some intracellular proteins. Our results provide novel clues for understanding the mechanisms by which SVMPs induce damage to the microvasculature and generate hemorrhage.This work was performed in partial fulfillment of the requirements for the PhD degree for Cristina Herrera at Universidad de Costa Rica.Peer reviewe
