    Epidemiology, clinical characteristics and severity of gradual onset injuries in recreational road cyclists: A cross-sectional study in 21,824 cyclists - SAFER XIII
    (Elsevier, 2020) Swanevelder, Sonja; Du Toit, François; Schwellnus, MP
    Objectives: Prevalence, clinical characteristics and severity of gradual onset injuries (GOIs) in cyclists are poorly documented. We determine the prevalence, anatomical regions/sites affected and severity of GOIs among entrants in a community-based mass participation event. Design: Cross-sectional study; Setting: Cape Town Cycle Tour; Participants: Race entrants. Main outcome measures: Of 35,914 entrants, 27,349 completed pre-race medical questionnaires. We studied 21,824 consenting cyclists (60.8% of entrants). Crude lifetime prevalence, retrospective annual incidence, anatomical region/sites, specific GOI, tissue type and GOI severity is reported. Results: The lifetime prevalence of GOIs was 2.8%, with an annual incidence of 2.5%. More common anatomical regions affected by GOIs were lower limb (43.4%), upper limb (19.8%), and lower back (11.5%). The knee (26.3%), shoulder (13%), and lower back (11.5%) regions were mostly affected. The most common GOI was anterior knee pain (14.2%). Of the GOIs, 55% were in soft tissue. 50% of cyclists reported symptom duration >12 months, and 37.3% of GOIs were severe enough to reduce/prevent cycling. Conclusion: 2.5% recreational cyclists report a GOI annually. >50% of GOIs affect the knee, lower back and shoulder. GOIs negatively affect cycling. Risk factors related to GOIs in cyclists need to be determined to develop and implement prevention programs.

    History of chronic disease is a novel intrinsic risk factor associated with gradual onset injuries in recreational road cyclists: A cross-sectional study in 21,824 cyclists - SAFER XIV
    (Elsevier, 2020) Du Toit, François; Sonja, Swanevelder; Schwellnus, MP
    Objectives: Risk factors related to Gradual onset injuries (GOIs) in cyclists need to be identified to enable effective injury prevention strategies. We aim to determine risk factors related to GOIs in cyclists participating in mass community-based events. Design: Cross-sectional study. Setting: Cape Town Cycle Tour. Participants: Race entrants (n = 35,914) Main outcome measures: Completion of pre-race medical questionnaires. 21,824 consenting cyclists (60.8%) were studied. 617 cyclists reported GOIs. Selected risk factors associated with GOIs: demographics, training/racing history, chronic disease history, and medication use, were explored using multi-variate analyses. Results: Prevalence ratio (PR) of GOIs was similar in males and females, but higher in older age categories [>50 yrs vs. categories: ≤30yrs (PR = 1.6); 31 to ≤40yrs (PR = 1.5); 41 to <50yrs (PR = 1.4)] (p < 0.0001). Intrinsic risk factors associated with GOIs (adjusted for gender and age) were: 1) increased weekly training/racing frequency (PR = 1.1, p = 0.0003), 2) chronic disease history [cardiovascular disease symptoms (PR = 2.3, p = 0.0026), respiratory disease (PR = 1.6, p < 0.0001), nervous system/psychiatric disease (PR = 1.5, p = 0.0082)], and 3) history of analgesic/anti-inflammatory medication (AAIM) used before/during racing (PR = 5.1, p < 0.0001).

    An overview of the regulation and management of cryptocurrency in South African inter vivos and testamentary trusts.
    (University of the Western Cape, 2021) Sylvester, Brandon; Du Toit, François
    Our lives, work, and behaviour have been changed both positively and negatively by the digital presence that has grown tremendously over the last three decades, and with this exponential growth, we cannot predict where we will be, digitally-speaking, in the years to come. As it stands in South Africa and the majority of the world today, we find that the law is yet to catch up to the technological explosion, in particular to the concept of digital assets. Digital material that is produced and purchased form a big part of our daily lives as we continue to consume media online, use social media platforms, and invest in cryptocurrency. The question of whether South African law makes sufficient provision for the incorporation of digital assets and, in particular, cryptocurrency in inter vivos or testamentary trust is yet to be fully established.
