    This thesis represents a discussion and critical appraisal of a selected number of research articles published in international peer-reviewed journals in the field of sports medicine and orthopaedic surgery. This work reflects over 5 years of dedication and passion in the field of golf medicine. The research is novel in a number of domains including assessing rates of COVID-19 in elite golfers, rates of returning to golf following orthopaedic surgery, and introducing new methods to this field. This body of work was initially planned to be focussed on the injuries of elite golfers however, two unique scenarios arose early in the process. The first was the COVID-19 pandemic and the need for evidence-based protocols for conducting professional golf events. The second was the opportunity for international collaboration around returning to golf following orthopaedic surgery which developed during the 2nd International Congress for Golf and Health. Therefore, this thesis is divided into two themes; the first on injuries and illnesses in golfers and the second on returning to golf following orthopaedic surgery. The thesis contains; two retrospective studies, four prospective studies, one prospective study protocol, one systematic review, one systematic review/meta-analysis, one narrative review, one consensus statement, one letter to the editor and one infographic. It flows in chronological order from theme one into theme two which represents the strategy in place moving from one project to another and the interconnected nature of each study. There was a small amount of overlap as theme two began and theme 1 concluded and this represents the opportunity to begin collaborative work following the golf and health congress. Each study is critically appraised in turn covering the aims and objectives, methodology, results and conclusions as well the contribution of the study to the literature and my own contribution. This thesis builds on existing research, identifies knowledge gaps, and presents reviews and original research that contribute to and enhance knowledge in the area of golf injury and illness.

    Risk assessment and implementation of risk reduction measures is not associated with increased transmission of SARS-CoV-2 compared with standard isolation at professional golf events.

    Objectives The purpose of this prospective study was to report incidence and transmission of SARS-CoV-2, among professional golfers and essential support staff undergoing risk assessment and enhanced risk reduction measures when considered a close contact as opposed to standard isolation while competing on the DP World Tour during the 2021 season. Methods This prospective cohort study included all players and essential support staff participating in 26 DP World Tour events from 18 April 2021 to 21 November 2021. High-risk contacts were isolated for 10 days. Moderate-risk contacts received education regarding enhanced medical surveillance, had daily rapid antigen testing for 5‚ÄČdays, with reverse transcriptase-polymerase chain reaction (RT-PCR) tesing on day 5, mandated mask use and access to outside space for work purposes only. Low-risk contacts typically received rapid antigen testing every 48 hours and RT-PCR testing on day 5. Results The total study cohort compromised 13‚ÄČ394 person-weeks of exposure. There were a total of 30 positive cases over the study period. Eleven contacts were stratified as 'high risk'. Two of these subsequently tested positive for SARS-CoV-2. There were 79 moderate-risk contact and 73 low-risk contacts. One moderate-risk contact subsequently tested positive for SARS-CoV-2 but did not transmit the virus. All other contacts, remained negative and asymptomatic to the end of the tournament week. Conclusions A risk assessment and risk reduction-based approach to contact tracing was safe in this professional golf event setting when Alpha and Delta were the predominant variants. It enabled professional golfers and essential support staff to work

    The journey so far : professional sport during the COVID-19 pandemic

    BACKGROUND : The COVID-19 pandemic has profoundly impacted community and professional sports. Throughout this time, sports organisations collaborated closely with the WHO, host national governments and their public health authorities. The common goals were to assess risk and to implement risk reduction measures to facilitate a stepwise return to sport, thus realising the physical and mental health benefits of sport for the participants, as well as the safe resumption of competitive events despite active SARS-CoV-2 transmission in many countries.https://bmjopensem.bmj.comSports Medicin

    The Need for Laboratory Measurements and Ab Initio Studies to Aid Understanding of Exoplanetary Atmospheres

    We are now on a clear trajectory for improvements in exoplanet observations that will revolutionize our ability to characterize their atmospheric structure, composition, and circulation, from gas giants to rocky planets. However, exoplanet atmospheric models capable of interpreting the upcoming observations are often limited by insufficiencies in the laboratory and theoretical data that serve as critical inputs to atmospheric physical and chemical tools. Here we provide an up-to-date and condensed description of areas where laboratory and/or ab initio investigations could fill critical gaps in our ability to model exoplanet atmospheric opacities, clouds, and chemistry, building off a larger 2016 white paper, and endorsed by the NAS Exoplanet Science Strategy report. Now is the ideal time for progress in these areas, but this progress requires better access to, understanding of, and training in the production of spectroscopic data as well as a better insight into chemical reaction kinetics both thermal and radiation-induced at a broad range of temperatures. Given that most published efforts have emphasized relatively Earth-like conditions, we can expect significant and enlightening discoveries as emphasis moves to the exotic atmospheres of exoplanets.Comment: Submitted as an Astro2020 Science White Pape

    Search for a Technicolor omega_T Particle in Events with a Photon and a b-quark Jet at CDF

    Full text link
    If the Technicolor omega_T particle exists, a likely decay mode is omega_T -> gamma pi_T, followed by pi_T -> bb-bar, yielding the signature gamma bb-bar. We have searched 85 pb^-1 of data collected by the CDF experiment at the Fermilab Tevatron for events with a photon and two jets, where one of the jets must contain a secondary vertex implying the presence of a b quark. We find no excess of events above standard model expectations. We express the result of an exclusion region in the M_omega_T - M_pi_T mass plane.Comment: 14 pages, 2 figures.

    Resonant nonlinear magneto-optical effects in atoms

    In this article, we review the history, current status, physical mechanisms, experimental methods, and applications of nonlinear magneto-optical effects in atomic vapors. We begin by describing the pioneering work of Macaluso and Corbino over a century ago on linear magneto-optical effects (in which the properties of the medium do not depend on the light power) in the vicinity of atomic resonances, and contrast these effects with various nonlinear magneto-optical phenomena that have been studied both theoretically and experimentally since the late 1960s. In recent years, the field of nonlinear magneto-optics has experienced a revival of interest that has led to a number of developments, including the observation of ultra-narrow (1-Hz) magneto-optical resonances, applications in sensitive magnetometry, nonlinear magneto-optical tomography, and the possibility of a search for parity- and time-reversal-invariance violation in atoms.Comment: 51 pages, 23 figures, to appear in Rev.
