RESUMO
Many potential applications of artificial intelligence involve making real-time decisions in physical systems while interacting with humans. Automobile racing represents an extreme example of these conditions; drivers must execute complex tactical manoeuvres to pass or block opponents while operating their vehicles at their traction limits1. Racing simulations, such as the PlayStation game Gran Turismo, faithfully reproduce the non-linear control challenges of real race cars while also encapsulating the complex multi-agent interactions. Here we describe how we trained agents for Gran Turismo that can compete with the world's best e-sports drivers. We combine state-of-the-art, model-free, deep reinforcement learning algorithms with mixed-scenario training to learn an integrated control policy that combines exceptional speed with impressive tactics. In addition, we construct a reward function that enables the agent to be competitive while adhering to racing's important, but under-specified, sportsmanship rules. We demonstrate the capabilities of our agent, Gran Turismo Sophy, by winning a head-to-head competition against four of the world's best Gran Turismo drivers. By describing how we trained championship-level racers, we demonstrate the possibilities and challenges of using these techniques to control complex dynamical systems in domains where agents must respect imprecisely defined human norms.

Honeybees (Apis mellifera carnica) communicate the direction and distance to a food source by means of a waggle dance. We ask whether bees recruited by the dance use it only as a flying instruction, with the technical form of a polar vector, or also translate it into a location vector that enables them to set courses directed toward the food source from arbitrary locations within their familiar territory. The flights of recruits captured on exiting the hive and released at distant sites were tracked by radar. The recruits performed first a straight flight in approximately the compass direction indicated by the dance. However, this "vector" portion of their flights and the ensuing tortuous "search" portion were strongly and differentially affected by the release site. Searches were biased toward the true location of the food and away from the location specified by translating the origin for the danced polar vector to the release site. We conclude that by following the dance recruits get two messages, a polar flying instruction (bearing and range from the hive) and a location vector that enables them to approach the source from anywhere in their familiar territory. The dance communication is much richer than thought so far.

BACKGROUND: Understanding the incidence, causes, and trends of sudden cardiac death (SCD) among young competitive athletes is critical to inform preventive policies. METHODS: This study included National Collegiate Athletic Association athlete deaths during a 20-year time frame (July 1, 2002, through June 30, 2022). Athlete deaths were identified through 4 separate independent databases and search strategies (National Collegiate Athletic Association resolutions list, Parent Heart Watch database and media reports, National Center for Catastrophic Sports Injury Research database, and insurance claims). Autopsy reports and medical history were reviewed by an expert panel to adjudicate causes of SCD. RESULTS: A total of 143 SCD cases in National Collegiate Athletic Association athletes were identified from 1102 total deaths. The National Collegiate Athletic Association resolutions list identified 117 of 143 (82%), the Parent Heart Watch database or media reports identified 89 of 143 (62%), the National Center for Catastrophic Sports Injury Research database identified 63 of 143 (44%), and insurance claims identified 27 of 143 (19%) SCD cases. The overall incidence of SCD was 1:63 682 athlete-years (95% CI, 1:54 065-1:75 010). Incidence was higher in male athletes than in female athletes (1:43 348 [95% CI, 1:36 228-1:51 867] versus 1:164 504 [95% CI, 1:110 552-1:244 787] athlete-years, respectively) and Black athletes compared with White athletes (1:26 704 [1:20 417-1:34 925] versus 1:74 581 [1:60 247-1:92 326] athlete-years, respectively). The highest incidence of SCD was among Division I male basketball players (1:8188 [White, 1:5848; Black, 1:7696 athlete-years]). The incidence rate for SCD decreased over the study period (5-year incidence rate ratio, 0.71 [95% CI, 0.61-0.82]), whereas the rate of noncardiovascular deaths remained stable (5-year incidence rate ratio, 0.98 [95% CI, 0.94-1.04]). Autopsy-negative sudden unexplained death (19.5%) was the most common postmortem examination finding, followed by idiopathic left ventricular hypertrophy or possible cardiomyopathy (16.9%) and hypertrophic cardiomyopathy (12.7%), in cases with enough information for adjudication (118 of 143). Eight cases of death were attributable to myocarditis over the study period (1 case from January 1, 2020, through June 30, 2022), with none attributed to COVID-19 infection. SCD events were exertional in 50% of cases. Exertional SCD was more common among those with coronary artery anomalies (100%) and arrhythmogenic cardiomyopathy (83%). CONCLUSIONS: The incidence of SCD in college athletes has decreased. Male sex, Black race, and basketball are associated with a higher incidence of SCD.

Association between genomic variants and athletic performance has seen a high degree of controversy, as there is often conflicting data as far as the association of genomic variants with endurance, speed and strength is concerned. Here, findings from a thorough meta-analysis from 4228 articles exploring the association of genomic variants with athletic performance in power and endurance sports are summarized, aiming to confirm or overrule the association of genetic variants with athletic performance of all types. From the 4228 articles, only 107 were eligible for further analysis, including 37 different genes. From these, there were 21 articles for the ACE gene, 29 articles for the ACTN3 gene and 8 articles for both the ACE and ACTN3 genes, including 54,382 subjects in total, from which 11,501 were endurance and power athletes and 42,881 control subjects. These data show that there is no statistically significant association between genomic variants and athletic performance either for endurance or power sports, underlying the fact that it is highly risky and even unethical to make such genetic testing services for athletic performance available to the general public. Overall, a strict regulatory monitoring should be exercised by health and other legislative authorities to protect the public from such services from an emerging discipline that still lacks the necessary scientific evidence and subsequent regulatory approval.

The 2022 FIFA World Cup was the first major multi-continental sporting Mass Gathering Event (MGE) of the post COVID-19 era to allow foreign spectators. Such large-scale MGEs can potentially lead to outbreaks of infectious disease and contribute to the global dissemination of such pathogens. Here we adapt previous work and create a generalisable model framework for assessing the use of disease control strategies at such events, in terms of reducing infections and hospitalisations. This framework utilises a combination of meta-populations based on clusters of people and their vaccination status, Ordinary Differential Equation integration between fixed time events, and Latin Hypercube sampling. We use the FIFA 2022 World Cup as a case study for this framework (modelling each match as independent 7 day MGEs). Pre-travel screenings of visitors were found to have little effect in reducing COVID-19 infections and hospitalisations. With pre-match screenings of spectators and match staff being more effective. Rapid Antigen (RA) screenings 0.5 days before match day performed similarly to RT-PCR screenings 1.5 days before match day. Combinations of pre-travel and pre-match testing led to improvements. However, a policy of ensuring that all visitors had a COVID-19 vaccination (second or booster dose) within a few months before departure proved to be much more efficacious. The State of Qatar abandoned all COVID-19 related travel testing and vaccination requirements over the period of the World Cup. Our work suggests that the State of Qatar may have been correct in abandoning the pre-travel testing of visitors. However, there was a spike in COVID-19 cases and hospitalisations within Qatar over the World Cup. Given our findings and the spike in cases, we suggest a policy requiring visitors to have had a recent COVID-19 vaccination should have been in place to reduce cases and hospitalisations.

Mass gatherings include a diverse range of events such as sporting competitions, religious ceremonies, entertainment activities, political rallies and cultural celebrations, which have important implications for population well-being. However, if not managed properly, these events can amplify health risks including those related to communicable diseases, and place undue strain on health systems in host countries and potentially in attendees' home countries, upon their return. The coronavirus disease 2019 (COVID-19) pandemic has provided a unique opportunity to evaluate the risk factors associated with mass gatherings and the effectiveness of applying mitigation measures during infectious disease emergencies. The pandemic has also allowed event organizers and health officials to identify best practices for mass gathering planning in host countries. To guide decisions about whether to hold, postpone, modify or cancel a mass gathering during the COVID-19 pandemic, the World Health Organization and its partners developed normative guidance and derivative tools promoting a risk-based approach to mass gathering planning. This approach involves three steps to guide decision-making around mass gatherings: risk evaluation, risk mitigation and risk communication. The approach was applied in the planning and execution of several mass gathering events, including the Tokyo 2020 and Beijing 2022 Olympic and Paralympic Games. Lessons identified from these large-scale international events offer insights into the planning and implementation of mass gathering events during a pandemic, and the broader impacts of such events on society. These lessons may also further inform and refine planning for future mass gatherings.
Les rassemblements de masse désignent un large éventail d'événements tels que des compétitions sportives, cérémonies religieuses, activités de divertissement, manifestations politiques et fêtes culturelles. Tous ont un impact considérable sur le bien-être de la population. Toutefois, s'ils ne sont pas gérés correctement, ils peuvent augmenter les risques sanitaires, notamment concernant les maladies transmissibles, et exercer une pression excessive sur les systèmes de santé des pays hôtes, voire sur ceux des pays d'origine des participants après leur retour. La pandémie de maladie à coronavirus 2019 (COVID-19) a offert une occasion unique d'évaluer les facteurs de risque associés aux rassemblements de masse, ainsi que l'efficacité des mesures visant à limiter la propagation dans des situations d'urgence liées à des maladies infectieuses. Cette pandémie a également permis aux organisateurs d'événements et responsables de santé d'identifier les bonnes pratiques à appliquer dans les pays hôtes pendant les rassemblements de masse. Afin de guider les décisions relatives au maintien, au report, à la modification ou à l'annulation d'un rassemblement de masse durant la pandémie de COVID-19, l'Organisation mondiale de la Santé et ses partenaires ont mis au point des orientations normatives et des outils dérivés favorisant une approche tenant compte des risques au moment de la planification. Cette approche comprend trois étapes contribuant à la prise de décision: l'évaluation, la réduction et la communication des risques. Elle a été déployée lors de la planification et de l'exécution de nombreux rassemblements de masse, comme les Jeux olympiques et paralympiques de Tokyo 2020 et Beijing 2022. Les leçons tirées de ces événements internationaux à grande échelle fournissent des informations sur leur organisation et leur mise en Åuvre en cas de pandémie, ainsi que les impacts de tels événements sur la société. Elles sont en outre susceptibles de faciliter et d'améliorer la planification des futurs rassemblements de masse.
Las concentraciones masivas incluyen una gran variedad de eventos, como competiciones deportivas, ceremonias religiosas, actividades de entretenimiento, mítines políticos y celebraciones culturales, que tienen importantes implicaciones para el bienestar de la población. Sin embargo, si no se gestionan adecuadamente, estos eventos pueden amplificar los riesgos para la salud, incluidos los relacionados con las enfermedades transmisibles, y suponer una carga excesiva para los sistemas sanitarios de los países anfitriones y, potencialmente, de los países de origen de los participantes a su regreso. La pandemia de la enfermedad por coronavirus de 2019 (COVID-19) ha brindado una oportunidad única para evaluar los factores de riesgo asociados a las concentraciones masivas y la eficacia de aplicar medidas de mitigación durante las emergencias por enfermedades infecciosas. La pandemia también ha permitido a los organizadores de eventos y a las autoridades sanitarias identificar las mejores prácticas para la planificación de concentraciones masivas en los países anfitriones. Para orientar las decisiones sobre la celebración, el aplazamiento, la modificación o la cancelación de una concentración masiva durante la pandemia de la COVID-19, la Organización Mundial de la Salud y sus asociados elaboraron orientaciones normativas y herramientas derivadas que promueven un enfoque de la planificación de concentraciones masivas basado en los riesgos. Este enfoque consta de tres pasos para orientar la toma de decisiones en torno a las concentraciones masivas: la evaluación, la mitigación y la comunicación de riesgos. El enfoque se aplicó en la planificación y ejecución de varias concentraciones masivas, incluidos los Juegos Olímpicos y Paralímpicos de Tokio 2020 y Pekín 2022. Las conclusiones extraídas de estos eventos internacionales a gran escala permiten comprender mejor la planificación y ejecución de concentraciones masivas durante una pandemia, así como las repercusiones más generales de estos eventos en la sociedad. Estas lecciones también pueden informar y perfeccionar la planificación de futuras concentraciones masivas.

PURPOSE OF REVIEW: Hypertrophic cardiomyopathy (HCM) is one of the most common cardiovascular genetic conditions. Although most patients with HCM typically do well clinically, there is a small but real incidence of sudden cardiac death. A diagnosis of HCM was previously a reason for complete exclusion in sports, particularly competitive sports.However, many of these recommendations are based on expert consensus, and much data has been published in the last decade furthering the scientific knowledge in this area, and allowing athletes who may have been previously excluded the potential to participate in strenuous activities and competitive sports. RECENT FINDINGS: With recent publications on participation in sports with HCM, as well as an emphasis on shared decision-making, more athletes with HCM are participating in competitive sports, even at a professional level. Even contact sports in the presence of an implantable cardioverter-defibrillator are no longer mutually exclusive in the current era. SUMMARY: Previous guidelines were likely overly restrictive for patients with HCM. Although there is a risk of sudden death that cannot be ignored, the potential for shared decision making as well as medical guidance are entering a new era in all aspects of medicine, particularly in sports participation.

AIM: To evaluate the association between physical activity (PA) and sports participation with insulin resistance and non-alcoholic fatty liver disease (NAFLD) in people with type 1 diabetes (T1D). METHODS: People with T1D from a secondary and tertiary care centre were included. Questionnaire-derived PA was expressed in metabolic equivalent of task hours per week (METh/week). Insulin sensitivity was calculated with the estimated glucose disposal rate (eGDR). NAFLD was assessed by transient elastography (TE). Multivariate linear and logistic regression models were conducted, adjusted for age, sex, diabetes duration and BMI. RESULTS: In total, 254 participants were included (men 56%, age 44 ± 14 years, diabetes duration 24 ± 14 years, median BMI 24.8 kg/m2), of which 150 participants underwent TE. Total PA (median 50.7 METh/week) was not significantly associated with insulin resistance (median eGDR 7.31 mg/kg/min) (beta -0.00, 95% CI -0.01 to 0.00) or with NAFLD (OR 1.00, 95% CI 0.99-1.01). Participating in sports was significantly associated with eGDR (beta 0.94, 95% CI 0.48-1.41) and with NAFLD (OR 0.21, 95% CI 0.08-0.56). CONCLUSIONS: In our T1D population, we could not find any dose-dependent association between PA, insulin resistance and NAFLD. People participating in sports had a lower degree of insulin resistance and lower odds for NAFLD.

Physical inactivity is a global health problem. Childhood is an opportune time to establish healthy physical activity behaviors, including the participation in organized physical activity, such as sports. We hypothesize that financial incentives can improve young people's participation in physical activity and sports. The design of the incentive and the context in which it operates are crucial to its success.

BACKGROUND: Community-level group sports participation is a structural aspect of social capital that can potentially impact individual health in a contextual manner. This study aimed to investigate contextual relationship between the community-level prevalence of group sports participation and the risk of all-cause, cardiovascular disease (CVD), and cancer mortality in older adults. METHODS: In this 7-year longitudinal cohort study, data from the Japan Gerontological Evaluation Study, a nationwide survey encompassing 43,088 functionally independent older adults residing in 311 communities, were used. Cause of death data were derived from the Japanese governmental agency, The Ministry of Health, Labour and Welfare, for secondary use. "Participation" was defined as engaging in group sports for one or more days per month. To analyze the data, a two-level survival analysis was employed, and hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated. RESULTS: Among the participants, 5,711 (13.3%) deaths were identified, with 1,311 related to CVD and 2,349 to cancer. The average group sports participation rate was 28.3% (range, 10.0-52.7%). After adjusting for individual-level group sports participation and potential confounders, a higher community-level group sports participation rate was found to be significantly associated with a lower risk of both all-cause mortality (HR: 0.89, 95% CI: 0.83-0.95) and cancer mortality (HR: 0.89, 95% CI: 0.81-0.98) for every 10% point increase in the participation rate. For CVD mortality, the association became less significant in the model adjusted for all covariates (HR: 0.94, 95% CI: 0.82-1.09). CONCLUSIONS: Our findings support the existence of a preventive relationship between community-level group sports participation and the occurrence of all-cause and cancer mortality among older individuals. Promoting group sports within communities holds promise as an effective population-based strategy for extending life expectancy, regardless of individual participation in these groups.

OBJECTIVE: Sports participation is lower in people of Turkish and Moroccan origin in the Netherlands than in native Dutch people. Addressing this inequality calls for better insights into antecedents of sports participation in different ethnic groups. Theorists suggested that loneliness may hamper sports participation, and levels of loneliness are high among people of Turkish and Moroccan origin. This study assessed the longitudinal association between loneliness and regular sports participation among Turkish origin, Moroccan origin and native Dutch people. METHODS: Data are from Turkish origin (n = 394), Moroccan origin (n = 387) and native Dutch (n = 1663) people who participated in Wave 1 (2008-2010) and Wave 2 (2013) of the Netherlands Longitudinal Lifecourse Study. Regular sports participation at follow-up was regressed on loneliness at baseline in logistic regression models adjusted for baseline sports participation and a range of confounders. Models were stratified by ethnic group. RESULTS: Turkish and Moroccan origin people had lower rates of regular sports participation and higher levels of loneliness than native Dutch people. Loneliness at baseline was negatively associated with sports participation at follow-up for people of Turkish and Moroccan origin. No evidence of a longitudinal association between loneliness and sports participation among native Dutch people was found. CONCLUSIONS: The demonstrated positive longitudinal association between loneliness and regular sports participation in people of Turkish and Moroccan origin potentially opens new ways to encourage physical activity in these groups. An integrated approach to addressing loneliness and physical inactivity among people with a non-western migration background may benefit the realization of both goals.

OBJECTIVE: The menstrual cycle often presents barriers to participation in daily life activities, including physical activity (PA), which is a cornerstone of health and well-being. The purpose of this systematic review was to explore and summarize the impact of symptoms, experiences, and perceptions of the menstrual cycle on recreational PA (RPA), including sports, exercise and active recreation, in the general population. METHODS: Six databases were searched for studies that investigated the impact of the menstrual cycle on PA among individuals who were cyclically menstruating, healthy, and not involved in professional sports training. RESULTS: The search yielded 3025 studies that were screened for relevance and eligibility, resulting in 25 eligible studies, which were found to be of moderate-to-high quality following a quality and risk-of-bias assessment. Thematic synthesis of qualitative and quantitative data from the selected studies, constituting 16,557 adults and 3715 adolescents, identified the impact of menstrual symptoms on the physical and psychological capability to participate in RPA, social opportunity barriers to RPA (e.g., social pressure due to the sociocultural taboo against menstruation), as well reflective (knowledge) and automatic (habit) motivation on RPA behaviours. CONCLUSION: The variability in menstrual symptoms and corresponding experiences suggested the need for an individualized approach to RPA promotion. Furthermore, this review highlighted the need to address the sociocultural taboo against menstruation, as well as improve the provision of knowledge and resources related to the menstrual cycle and RPA, in order to promote and facilitate RPA for cyclically menstruating individuals throughout the menstrual cycle.

Embodied mental rotation is the influence of the body on mental rotation ability. Sports expertise enhances embodied mental rotation ability. However, sport-skill-dependent effects remain unclear. Previous studies refer to the influence of body positions on mental rotation ability. Yet, in sports, the investigation of the effect of simultaneous body and mental rotation movements is essential. Athletes need to constantly mentally and physically adapt to environmental changes and new motor tasks while being in motion themselves. This study aimed to investigate embodied mental rotation ability with simultaneous body and mental rotation in individuals with different sport skills, i.e., in open- and closed-skill sports. Forty-eight men and women, divided into two groups depending on their sport, performed 32 trials of an extended embodied mental rotation task. Simultaneous body and mental rotation were enabled by a novel test method including Virtual Reality. Results revealed shorter response times to the task stimulus in closed-skill sports participants than in open-skill sports participants. This group difference was significant for trials in which rotation directions of the own body and the mental rotation stimulus were aligned. The results might be related to sport-specific skill development processes. Motor imitation skills, as relevant in many closed-skill sports, may facilitate cognitive processes when the motion direction of the own body and of the mental rotation stimulus are aligned. The novel test method identifies potential applications that should be increasingly explored in the future, both for cognitive science and sports research.

Emergency physicians are expected to learn and maintain a large and varied set of competencies for clinical practice. These include high acuity, low occurrence procedures that may not be encountered frequently in the clinical environment and are difficult to practice with high fidelity and frequency in a simulated environment. Mental practice is a form of a cognitive walk-through that has been shown to be an effective method for improving motor and cognitive skills, with literature in sports science and emerging evidence supporting its use in medicine. In this article, we review the literature on mental practice in sports and medicine as well as the underlying neuroscientific theories that support its use. We review best-known practices and provide a framework to design and use mental imagery scripts to augment learning and maintaining the competencies necessary for physicians at all levels of training and clinical environments in the practice of emergency medicine.

The rapid growth of the Internet of Things and wearable sensors has led to advancements in monitoring technology in the field of health. One such advancement is the development of wearable respiratory sensors, which offer a new approach to real-time respiratory monitoring compared to traditional methods. However, the energy consumption of these sensors raises concerns about environmental pollution. To address the issue, this study proposes the use of a triboelectric nanogenerator (TENG) as a sustainable energy source. The electrical conductivity of the TENG is improved by incorporating chitosan and carbon nanotubes, with the added benefit of chitosan's biodegradability reducing negative environmental impact. A wireless intelligent respiratory monitoring system (WIRMS) is then introduced, which utilizes a degradable triboelectric nanogenerator for real-time respiratory monitoring, diagnosis, and prevention of obstructive respiratory diseases. WIRMS offers stable and highly accurate respiratory information monitoring, while enabling real-time and nondestructive transmission of information. In addition, machine learning technology is used for sleep respiration state analysis. The potential applications of WIRMS extend to wearables, medical monitoring and sports monitoring, thereby presenting innovative ideas for modern medical and sports monitoring.

BACKGROUND: School attendance and life participation, particularly sport, is a high priority for children with chronic kidney disease (CKD). This study is aimed at assessing the association between CKD stage, sports participation, and school absences in children with CKD. METHODS: Using data from the binational Kids with CKD study (ages 6-18 years, n = 377), we performed multivariable regression to evaluate the association between CKD stage, school absences, and sports participation. RESULTS: Overall, 62% of participants played sport with the most frequent sport activities engaged in being swimming (17%) and soccer (17%). Compared to children with CKD 1-2, the incidence rate ratios (IRR) (95% CI) for sports participation amongst children with CKD 3-5, dialysis, or transplant were 0.84 (0.64-1.09), 0.59 (0.39-0.90), and 0.75 (0.58-0.96), respectively. The median (IQR) days of school absences within a four-week period were 1 day (0-1), with children on dialysis reporting the highest number of school absences (9 days (5-15)), followed by transplant recipients (2 days (1-7)), children with CKD 3-5 (1 day (0-3)), and with CKD 1-2 (1 day (0-3)). Duration of CKD modified the association between CKD stage and school absences, with children with a transplant experiencing a higher number of missed school days with increasing duration of CKD, but not in children with CKD 1-5 or on dialysis (p-interaction < 0.01). CONCLUSIONS: Children receiving dialysis and with a kidney transplant had greater school absences and played fewer sports compared to children with CKD stages 1-2. Innovative strategies to improve school attendance and sport participation are needed to improve life participation of children with CKD.

Imaging human brain function with techniques such as magnetoencephalography typically requires a subject to perform tasks while their head remains still within a restrictive scanner. This artificial environment makes the technique inaccessible to many people, and limits the experimental questions that can be addressed. For example, it has been difficult to apply neuroimaging to investigation of the neural substrates of cognitive development in babies and children, or to study processes in adults that require unconstrained head movement (such as spatial navigation). Here we describe a magnetoencephalography system that can be worn like a helmet, allowing free and natural movement during scanning. This is possible owing to the integration of quantum sensors, which do not rely on superconducting technology, with a system for nulling background magnetic fields. We demonstrate human electrophysiological measurement at millisecond resolution while subjects make natural movements, including head nodding, stretching, drinking and playing a ball game. Our results compare well to those of the current state-of-the-art, even when subjects make large head movements. The system opens up new possibilities for scanning any subject or patient group, with myriad applications such as characterization of the neurodevelopmental connectome, imaging subjects moving naturally in a virtual environment and investigating the pathophysiology of movement disorders.
