Abstract
OBJECTIVE To systematically review the literature and analyze clinical outcomes and return-to-sport after surgical management of cartilage injuries in football players. DESIGN A systematic literature review was performed in August 2023 on PubMed, WebOfScience, and Cochrane Library to collect studies on surgical strategies for cartilage lesions in football players. Methodological quality and risk of bias were assessed with the modified Coleman Methodology score and RoB2 and RoBANS2 tools. RESULTS Fifteen studies on 409 football players (86% men, 14% women) were included: nine prospective and two retrospective case series, one randomized controlled trial, one prospective comparative study, one case report, and one survey. Bone marrow stimulation (BMS) techniques were the most documented. The lesion size influenced the treatment choice: debridement was used for small lesions (1.1 cm2), BMS, osteochondral autograft transplantation (OAT), matrix-assisted autologous chondrocytes transplantation (MACT), and scaffold-augmented BMS for small/mid-size lesions (2.2-3.0 cm2), and autologous chondrocytes implantation (ACI) for larger lesions (5.8 cm2). The surgical options yielded different results in terms of clinical outcome and return-to-sport, with fastest recovery for debridement and scaffold-augmented BMS. The current evidence is limited with large methodological quality variation (modified Coleman Methodology score 43.5/100) and a high risk of bias. CONCLUSIONS Decision-making in cartilage injuries seems to privilege early return-to-sport, making debridement and microfractures the most used techniques. The lesion size influences the treatment choice. However, the current evidence is limited. Further studies are needed to confirm these findings and establish a case-based approach to treat cartilage injuries in football players based on the specific patient and lesion characteristics and the treatments' potential in terms of both return-to-sport and long-term results. LEVEL OF EVIDENCE Systematic review, level IV.

Abstract
The mechanical properties of cells and tissues help determine their architecture, composition and function. Alterations to these properties are associated with many diseases, including cancer. Tensional, compressive, adhesive, elastic and viscous properties of individual cells and multicellular tissues are mostly regulated by reorganization of the actomyosin and microtubule cytoskeletons and extracellular glycocalyx, which in turn drive many pathophysiological processes, including cancer progression. This Review provides an in-depth collection of quantitative data on diverse mechanical properties of living human cancer cells and tissues. Additionally, the implications of mechanical property changes for cancer development are discussed. An increased knowledge of the mechanical properties of the tumour microenvironment, as collected using biomechanical approaches capable of multi-timescale and multiparametric analyses, will provide a better understanding of the complex mechanical determinants of cancer organization and progression. This information can lead to a further understanding of resistance mechanisms to chemotherapies and immunotherapies and the metastatic cascade.

Abstract
Objective This pilot study aimed to evaluate the perception and satisfaction of deselected male Academy professional footballers towards a medical after-care intervention. Methods A quasiexperimental study design, with deselected players (aged≥18 years) at a single Premier League Academy during the 2022/2023 season, were invited to participate. The intervention included individualised health recommendations, key medical information and signposting to key support resources. Participants' perceptions and satisfaction were assessed through an electronic survey. Descriptive analyses (mean, SD, frequency and/or range) were performed for all variables. Results Twelve out of 15 eligible participants (80% response rate) provided informed consent and completed the survey (mean age: 19.5 years). All (100%) of the participants were satisfied with receiving the medical information. Ten out of 12 (83.3%) participants agreed that all Academy players should receive this medical intervention on deselection. Nine (75%) players felt more prepared for the next steps in their careers due to the medical information shared with them. Conclusion Deselected male Academy footballers expressed high satisfaction with an individualised medical intervention which shared key health information and signposted them to important resources (eg, mental health). Future studies across multiple clubs should explore the broader impact of this intervention among deselected male and female Academy footballers. Football clubs should consider integrating a medical after-care process for deselected players as part of routine care.

Abstract
Previous research suggests that psychological factors play an important role in trying to explain and predict the participation, performance, and health of player and practitioners in soccer. However, most previous works have focused on specific research questions and included samples from male populations. As part of a larger Fédération Internationale de Football Association (FIFA) project aiming to steer women's soccer research, our purpose with this scoping review was to give an overview of the current state of psychology-related research within women's soccer. We searched five electronic databases up to April 2023, from which 280 original peer-reviewed articles met the inclusion criteria. Included records were inductively coded into 75 specific research topics and nine broader research categories. Population characteristics within each topic and category, and overall publication trends, were identified. The results revealed a growth in research attention, with notable increases in publication rates around the international competitions years, over the last two decades. While a notable number of abstracts did not report sufficient details about population age and/or playing levels, senior elite players were identified as the most common population studied. Most studies examined several topics from different research categories, with research focusing on emotions, moods and/or environmental factors, and the specific the topics of anxiety, stress, and coach behavior, receiving most research attention. Our study provides an informative mapping of all psychology-related research activity within women's soccer, which will enhance researchers' understanding of the current quantity of literature within this complex, heterogeneous, and growing area of research.

Abstract
Several sports have published consensus statements on methods and reporting of epidemiological studies concerning injuries and illnesses with football (soccer) producing one of the first guidelines. This football-specific consensus statement was published in 2006 and required an update to align with scientific developments in the field. The International Olympic Committee (IOC) recently released a sports-generic consensus statement outlining methods for recording and reporting epidemiological data on injury and illness in sport and encouraged the development of sport-specific extensions.The Fédération Internationale de Football Association Medical Scientific Advisory Board established a panel of 16 football medicine and/or science experts, two players and one coach. With a foundation in the IOC consensus statement, the panel performed literature reviews on each included subtopic and performed two rounds of voting prior to and during a 2-day consensus meeting. The panel agreed on 40 of 75 pre-meeting and 21 of 44 meeting voting statements, respectively. The methodology and definitions presented in this comprehensive football-specific extension should ensure more consistent study designs, data collection procedures and use of nomenclature in future epidemiological studies of football injuries and illnesses regardless of setting. It should facilitate comparisons across studies and pooling of data.

Abstract
BACKGROUND We sought to assess the risk of COVID-19 and seasonal flu including respiratory syncytial (RSV) and influenza viruses during the FIFA Arab Cup 2021 in Qatar with full capacity of spectators. We also, evaluated the post-event attitude toward resumption of mass football events. METHODS This was a cross-sectional study in which spectators (age ≥ 18 years) were invited for reverse-transcription PCR testing for COVID-19 and seasonal flu. At the same time, between 7 and 14 days after the event, the participants completed a self-administered questionnaire regarding their concerns during the tournament. RESULTS The tournament included 16 international football teams from the Arab countries. As per the study protocol, 10,000 spectators were approached and 6,475 participated. Among the participants, 4,195 (65.1%), 2,253 (34.9%) and 27 (0.4%) were vaccinated with 2 doses, vaccinated with 3 doses, and recovered from SARS-Cov-2 infection, respectively. There were 61 (0.9%), 41(0.6%) and 11(0.2%) participants who tested positive for COVID-19, RSV and influenza (A/B), respectively. The average cycle threshold (Ct) value for COVID-19 positive cases was 26.1±7.3. Among those who were electronically approached, 6,102 completed the survey whereas 373 had incomplete survey. Overall, 2069 (33.9%) participants reported symptoms that theoretically could be related to COVID-19, of them 39 had positive PCR test (1.9%). Spectators (94.3%) were optimistic about returning sport events to the pre-pandemic status. CONCLUSIONS There was no significant increase in the daily COVID-19 cases during FIFA Arab Cup 2021 with a full capacity of spectators. Therefore, upcoming mass football events can be held safely.

Abstract
We used injury spotters and video footage review to establish the frequency of head impacts, their characteristics, and the subsequent medical assessment during the FIFA Arab Cup 2021TM. Six defined video signs of potential concussion based on an international consensus were used. A total of 88 head impacts were observed, with a median of 2 (IQR 1.5-4, range 0-7) head impacts per match, of which 44 (50%) resulted in on-pitch medical assessment. The median assessment duration was 51s (IQR 34-65s, range 19-262s). The most common mechanism was head-to-head contact (27% of all impacts and 43% of impacts with medical assessment). Seven head impacts showed video signs of potential concussion: six had one sign and one had two signs. The concussion substitution was used in three incidents. Head impacts during the FIFA Arab Cup were common and a median of 1 head impact per game required an on-pitch medical assessment. Only 8% of the head impacts showed any video sign of potential concussion, and only 3% resulted in a concussion substitution. The medical on-pitch assessments appeared too short (<1 min) to allow an appropriate assessment of all head impacts, indicating a need for further evaluation. Further standardisation of the injury spotter's role in football is recommended.

Abstract
Football (soccer) is a very popular team sport among African women and girls, with player numbers continuing to rise at all levels of the sport. Whereas the participation in football and associated injuries are on the rise, there are not enough sports and exercise medicine (SEM) personnel to attend to these women football players. While Africa may not currently have enough SEM trained medical doctors and/or physiotherapists, it has relatively higher numbers of other healthcare workers; for example, nurses, who lead healthcare services provision from community to tertiary levels. The primary objective of this study will be to compare sports medicine practices; injury prevention behaviours; injury risk parameters; incidence and prevalence of injuries and illnesses in teams with and without a Football Nurse during one competitive season in Malawi's Women's football league. This study will be a cluster randomised control trial will recruit 24 teams from the Women's Football League in Malawi, which will be randomised to either the intervention group or the control group. A cohort of 12 nurses will receive training in basic football medicine; after which they will be attached to a total of 12 women's football teams (intervention group) during one competitive season. The Football Nurses will be directly report to a physiotherapist or doctor in their district to whom they will refer serious injuries for investigations, or further management. The teams with Football Nurses will be compared to other teams that will not have Football Nurses. We expect to develop a low cost, sustainable and context relevant solution to manage the treatment gap of football injuries/illnesses in underserved communities such as women's football.

Abstract
OBJECTIVE To describe imaging-detected musculoskeletal injuries and image-guided interventional procedures during the 2022 FIFA football (soccer) World Cup. MATERIALS AND METHODS Retrospective analysis of all radiologic examinations performed in a central medical facility for athletes was performed by two board certified musculoskeletal radiologists. Data on muscle, tendon, ligament, cartilage, and bone injuries were collected according to imaging modality and body part. RESULTS A total of 143 radiology examinations in 94 athletes were evaluated at the central medical facility. Magnetic resonance imaging (MRI) was the most utilized modality (67%), followed by radiography (12%), ultrasonography (9%), and computed tomography (4%). Image-guided interventions corresponded to 8% of all radiological examinations. There were 112 injuries described, affecting muscles and tendons (42%), ligaments (25%), cartilage (21%), and bone (12%). Most injured body parts were thigh (27%), foot and ankle (23%), knee (23%), and hip/groin (8%). Most injured players were within the age range of 24-35 years old (71%). CONCLUSION Imaging was utilized in 11% of players who participated in the 2022 FIFA World Cup in Qatar. MRI was the most utilized modality, and acute muscle tears were the most diagnosed type of injury. Diagnostic imaging played an important role in diagnosing sports-related injuries during the 2022 FIFA World Cup.

Abstract
This review aimed, as part of a larger FIFA project aiming to steer women's football research, to scope literature on any level of competitive football for women, to understand the current quantity of research on women's football injuries. The study reviewed all injury-related papers scoped by a recent scoping review mapping all published women's football research with an updated search performed on 23 February 2021. Eligibility criteria assessment followed the recent scoping review with injury-specific research focus. A total of 497 studies were scoped. Most studies contained an epidemiological (N = 226; 45%) or risk factors assessment (N = 105; 21%). Less assessed areas included financial burden (N = 1; <1%) and injury awareness (N = 5; 1%). 159 studies (32%) assessed injuries of the whole body. The most common single location assessed in the literature was the knee (N = 134, 27%), followed by head/face (N =108, 22%). These numbers were, however, substantially lowered, when subdivided by playing level and age-group. The volume of research focuses especially on descriptive research and specific body locations (head/face and knee). Although information can be taken from studies in other sports, more football-specific studies to support management and prevention of injuries are warranted.

Abstract
Growing Miscanthus species and hybrids has received strong scientific and commercial support, with the majority of the carbon (C) modelling predictions having focused on the high-yield, sterile and noninvasive hybrid Miscanthus × giganteus. However, the potential of other species with contrasting phenotypic and physiological traits has been seldom explored. To better understand the mechanisms underlying C allocation dynamics in these bioenergy crops, we pulse-labelled (13CO2) intact plant-soil systems of Miscanthus × giganteus (GIG), Miscanthus sinensis (SIN) and Miscanthus lutarioriparius (LUT) and regularly analysed soil respiration, leaves, stems, rhizomes, roots and soils for up to 190 days until leaf senescence. A rapid isotopic enrichment of all three species was observed after 4 h, with the amount of 13C fixed into plant biomass being inversely related to their respective standing biomass prior to pulse-labelling (i.e., GIG < SIN < LUT). However, both GIG and LUT allocated more photoassimilates in the aboveground biomass (leaves+stems = 78 % and 74 %, respectively) than SIN, which transferred 30% of fixed 13C in its belowground biomass (rhizomes+roots). Although less fixed 13C was recovered from the soils (<1 %), both rhizospheric and bulk soils were signficantly more enriched under SIN and LUT than under GIG. Importantly, the soils under SIN emitted less CO2, which suggests it could be the best choice for reaching C neutrality. These results from this unique large-scale study indicate that careful species selection may hold the success for reaching net GHG mitigation.

Abstract
Background Knee osteoarthritis (OA) is common amongst retired male professional footballers. There is limited understanding with respect to the interplay between imaging findings, clinical presentation and patient-reported outcome measures (PROMs) in retired professional footballers with knee OA. Objectives This pilot study aimed to evaluate the extent of radiological and clinical knee OA in a cohort of retired male professional footballers, and to explore the relationship between these findings and knee-related PROMs. Methods Fifteen retired male professional footballers underwent knee radiographs and were surveyed on their history of clinical OA, severe knee injury and previous knee surgery. The Knee Injury and Osteoarthritis Outcome Score Physical Function Short Form (KOOS-PS) and the Patient-Reported Outcomes Measurement Information System Global Health (PROMIS-GH) were used to assess health outcomes, such as level of function and pain. Results Radiological knee OA was diagnosed in six out of 15 participants. Seven of the participants had a clinical diagnosis of knee OA. Evidence of clinical and radiological OA was present amongst four participants. Radiological knee OA and clinical OA was significantly associated with a history of severe knee injury and previous knee surgery. Low correlations (ρ<-0.40) were found between knee OA severity and knee-related PROMs. Moderate correlation (ρ=-0.65) was found between clinical knee OA and KOOS-SP. Conclusion Clinical knee OA correlates with PROMs amongst retired professional footballers but radiological OA does not. Further studies are required to understand the relationship between imaging findings, clinical presentation and PROMs amongst retired professional footballers with knee OA.

Abstract
This document presents the recommendations developed by the IOC Medical and Scientific Commission and several international federations (IF) on the protection of athletes competing in the heat. It is based on a working group, meetings, field experience and a Delphi process. The first section presents recommendations for event organisers to monitor environmental conditions before and during an event; to provide sufficient ice, shading and cooling; and to work with the IF to remove regulatory and logistical limitations. The second section summarises recommendations that are directly associated with athletes' behaviours, which include the role and methods for heat acclimation; the management of hydration; and adaptation to the warm-up and clothing. The third section explains the specific medical management of exertional heat stroke (EHS) from the field of play triage to the prehospital management in a dedicated heat deck, complementing the usual medical services. The fourth section provides an example for developing an environmental heat risk analysis for sport competitions across all IFs. In summary, while EHS is one of the leading life-threatening conditions for athletes, it is preventable and treatable with the proper risk mitigation and medical response. The protection of athletes competing in the heat involves the close cooperation of the local organising committee, the national and international federations, the athletes and their entourages and the medical team.

Abstract
AIM This study aims to scope available peer-reviewed literature published in a FIFA language to understand the current quantity of research on women's football. METHODS Five databases were searched on the 15/12/2019. Studies were included when containing original research published in a peer-reviewed journal around female competitive football of any level, any age and on any subject. Author, journal, title and abstract of all included studies were scoped. Population assessed number of participants, level of play, age level of football and publication theme(s) were extracted. RESULTS A total of 1,634 articles were scoped. The oldest publication dated back to 1939, whilst a total of 202 studies were gathered from 2019. The publication theme most frequently researched was sports medicine (N = 521) followed by strength and conditioning (N = 331) and sociology (N = 299). The majority of studies has focussed on elite (N = 442), senior (N = 977) players. CONCLUSION A continuous growth in research attention has been seen. However, the numbers are not comparable to current research output levels in men's football. This study represents an essential first step in a larger 'research agenda-setting' project to determine research priorities for women's football during the next 10 years.

Abstract
Abstract
Pancreatic cancer (PanCa) is the third leading cause of cancer-related deaths in the United States with limited therapeutic options available. Gemcitabine (GEM), a deoxycytidine nucleoside analog is currently considered the most effective therapy for PanCa; however, it shows only a marginal survival benefit of 6 months. PanCa cells are addicted to ribosome biogenesis (RiBi) which supports their high rate of growth and proliferation. Therefore, strategically targeting the process of RiBi could be one of the ideal strategies for the prevention and treatment of PanCa. In this study, we for the first-time report that RPA194, a catalytic subunit of RNA Pol I is differentially expressed in normal pancreatic ductal epithelial (NPDE) and cancer cells. We also observed differential expression of RPA194 in various grades of pancreatic tumor tissues and its level was increased in high-grade pancreatic tumor tissues. We tested our hypothesis that targeting RPA194 with a non-toxic pharmacological inhibitor (BMH-21) will inhibit the growth of advanced PanCa. We observed that BMH-21 inhibits the growth and induced apoptosis of PanCa cells in a dose-dependent manner and this inhibition was correlated with the expression of RPA194. We observed proteasomal mediated degradation of RPA194 in PanCa cells. BMH-21 treatment inhibited RPA194 occupancy on rDNA but did not affect other nucleolar proteins (UBF, fibrillarin, nucleolin, and nucleophosmin). Two times the effective concentration of BMH-21 (5 µM) did not show any cytotoxic effect in NPDE cells. However, BMH-21 degraded RPA 194 protein in these cells in a similar manner as in PanCa cells. Therefore, we speculate that other proteins are involved in the selective toxicity of BMH-21 in PanCa cells. These findings were translated to in vivo model systems. We observed that BMH-21 significantly (P<0.01) inhibited the growth of pancreatic tumors in an orthotopic xenograft model. This pancreatic tumor growth inhibition was correlated with degradation of RPA194 protein in BMH-21 treated mice tumor tissues followed by inhibition of cell proliferation markers (ki67 and PCNA). Taken together, our results strongly suggest that targeting the RiBi process is a novel approach and BMH-21 is a non-toxic potential targeting agent for the prevention and treatment of advanced PaCa.

Abstract
ObjectivesThe purpose of this study was to explore the leadership experiences of elite football team physicians during the COVID-19 pandemic.MethodsA pilot-study based on a cross-sectional design by means of an electronic survey was conducted. The survey relied on 25 questions divided into distinct sections including among others professional and academic experience, leadership experiences and perspectives.ResultsA total of 57 physicians (91% male; mean age: 43 years) gave their electronic informed consent and completed the survey. All participants agreed that the demands of their role had increased during the COVID-19 pandemic. Fifty-two (92%) participants reported that they felt they were expected to take more of a leadership role during the COVID-19 pandemic. Eighteen (35%) reported feeling under pressure to make clinical decisions which were not in keeping with best clinical practice. Additional roles, duties and demands expected of team doctors during the COVID-19 pandemic were subdivided into communication, decision-making, logistical, and public health demands.ConclusionThe findings from this pilot study suggest that the way in which team physicians at professional football clubs operate has altered since the onset of the COVID-19 pandemic, with greater demands placed on leadership skills including decision-making, communication and ethical stewardship. This has potential implications for sporting organisations, clinical practice and research.

Abstract
Pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States with limited therapeutic approaches. Dysregulation of the ribosome biogenesis process was observed in various cancer including pancreatic cancer. Therefore, strategically targeting ribosome biogenesis could be a novel approach for pancreatic cancer treatment. One such approach is to target ribosome biogenesis is via small molecule inhibitors of RNA Polymerase I as these inhibitors have shown promising anti-cancer activity in pre-clinical and clinical studies. We observed differential constitutive expression of various ribosomal proteins including RPA-194 in human PanCa cells when compared with normal HPDE cells. Therefore, we hypothesized that targeting RNA pol I will inhibit the growth of pancreatic cancer. In this study, we for the first time evaluated the therapeutic effect of a novel RNA polymerase I inhibitor (BMH-21) against PanCa in pre-clinical model systems. BMH-21 significantly inhibited the ribosome biogenesis process in various pancreatic cancer cells (Panc-1, AsPC1, BxPC3, MiaPaCa-2) as determined by inhibition of rRNA synthesis and POL I occupancy on rDNA. BMH-21 treatment of pancreatic cancer cells significantly degraded RPA194 protein as determined by Western blot and confocal microscopy analysis. BMH-21 treatment (0.25-5µM) showed differential IC50 in various pancreatic cancer cells which were correlated with the expression of its target proteins RPA194 and RPA135 expression. In our flow cytometry experiment, we observed a significant G0/G1 cell cycle arrest and increase Annexin V and Annexin V7-AAD positive cells in BMH-21 treated pancreatic cancer cells as compared to the vehicle treatment group suggesting its apoptosis-inducing potential in pancreatic cancer cells. BMH-21 treatment inhibited growth and metastatic phenotypes of various PanCa cells as analyzed by various functional assays (colony formation and atomic force microscopy analyses). We also evaluated the effect of BMH-21 on various kinases, which regulate ribosome biogenesis. Interestingly, we observed BMH-21 significantly (P<0.01) downregulated the phosphorylation of AKT (Ser473) and WNK-1 (Thr60) kinases and Stat3 phosphorylation at Ser727 and upregulates pChk2 kinase in PanCa cells. BMH-21 (2 mg/kg i.p) significantly (P<0.01) inhibited the growth of pancreatic tumor in an orthotopic xenograft mouse model. Excised tumor tissues of BMH-21 treated mice showed decreased expression of various ribosomal proteins including RPA194 and RPA195 along with various cell proliferative markers (ki67 and PCNA) as compared to vehicle-treated group. Taken together, our results demonstrated that targeting the ribosome biogenesis process is a novel therapeutic strategy for the management of pancreatic cancer and BMH-21 could be used as a potential therapeutic agent for the treatment of advanced pancreatic cancer.

Abstract
Objectives To identify the correlation between preseason body composition and incidence coupled with injury burden throughout the season in adult male professional football players. Methods A retrospective case series was performed for linear regression analysis of preseason body composition variables and injury data. R2 >0.10 was deemed of adequate correlation. Results All 36 professional football players in the male first team of an English Premier League professional football team were recruited, with none lost to follow-up. The total and mean incidence of injuries was 83.00 and 2.31 (95% CI 1.72 to 2.89), respectively. The mean injury burden was 58.32 (95% CI 37.67 to 78.98) days missed. Simple linear regression analysis indicated no significant or adequate correlations between incidence and preseason body composition variables. Injury burden revealed non-significant adequate negative correlations to body mass (R2=0.17), body mass index (BMI) (R2=0.15), waist circumference (R2=0.17), total bone mineral density (BMD) (R2=0.11) and mean embedded structures (R2=0.10). Conclusions Players with decreased body mass, BMI, waist circumference, total BMD and mean embedded structures may be prone to greater injury burden. Further studies with a larger sample size that incorporates multiple football teams are warranted to investigate this.

Abstract
Objective To conduct a scoping review providing an overview of the health conditions occuring in retired male and female professional footballers, with an emphasis on musculoskeletal, mental, neurocognitive, cardiovascular and reproductive health conditions. Methods In January 2022, a comprehensive systematic literature search in three databases (MEDLINE via PubMed, SPORTDiscus via EBSCOhost and EMBASE) was conducted for common health conditions among retired male and female professional footballers. Primary research studies (full text available online) which described the incidence or prevalence of a health condition (musculoskeletal, mental, neurocognitive, cardiovascular, reproductive) among retired male and female professional footballers were included for review. Case reports, qualitative research and grey literature were omitted. Results In total, 917 eligible articles were identified from the databases, with 41 meeting the eligibility criteria. Osteoarthritis of the hip, knee and ankle were found to be common among retired professional footballers. Mental health symptoms (eg, anxiety, depression) are experienced by retired male and female professional footballers. The incidence of neurocognitive disease appears to be higher among retired male professional footballers than among matched controls. There is very limited evidence examining the presence of health conditions in retired female professional footballers. Conclusion Osteoarthritis of the lower limb, musculoskeletal pain and mental health symptoms are common among retired professional footballers. Knowledge about the occurrence and timing of musculoskeletal, mental health and neurocognitive conditions among retired professional footballers can be used by a wide range of stakeholders to proactively intervene during and after a player’s career to mitigate risk.

Abstract
The cessation of amateur and recreational sport has had significant implications globally, impacting economic, social and health facets of population well-being. As a result, there is pressure to resume sport at all levels. The ongoing prevalence of SARS-CoV-2 and subsequent 'second waves' require urgent best practice guidelines to be developed to return recreational (non-elite) sports as quickly as possible while prioritising the well-being of the participants and support staff.This guidance document describes the need for such advice and the process of collating available evidence. Expert opinion is integrated into this document to provide uniform and pragmatic recommendations, thereby optimising on-field and field-side safety for all involved persons, including coaches, first responders and participants.The nature of SARS-CoV-2 transmission means that the use of some procedures performed during emergency care and resuscitation could potentially be hazardous, necessitating the need for guidance on the use of personal protective equipment, the allocation of predetermined areas to manage potentially infective cases and the governance and audit of the process.

Abstract
Abstract
Pancreatic cancer is one of the most lethal malignancies with a 5-year survival rate currently below 10%. Unfortunately, current diagnostic methods are unable to readily recognize early disease progression, and symptoms are commonly misdiagnosed. Therefore, determining novel biomarkers related to disease progression remains an important area of research. Transmembrane mucins, a major component of the cellular glycocalyx, normally play a protective role in epithelial tissues; they are also known to be overexpressed in various cancers, including pancreatic. In addition, mucins are known to increase aggressiveness, enhance drug resistance, and reduce survivability in cancers where they are upregulated. Although the biochemical effects of mucins are well understood, there is minimal research into how they affect cancer cells at a biophysical level. Recently, there has been great interest in examining the biophysical properties of cancer cells. The current consensus is that cancerous cells are softer than their normal counterparts, and that more metastatic cells become softer compared to more benign tumor cells. Measuring these physical properties could potentially give clinicians a more rapid way to diagnose tumors, determine the course of disease progression, physically determine the effect of a biomolecule when its expression is altered, or determine the efficacy of various chemotherapeutics. In this study, we will first use atomic force microscopy-based nanomechanical mapping to measure the biophysical differences between normal cells, cancerous cells, and the extracellular matrix extracted from human patient tumor tissues and track the measured changes, both before and after chemo treatments. Our preliminary in vitro results suggest that 2D-adherent human cancerous pancreatic cells are indeed softer than their normal counterparts, in agreement with the literature. In addition, modulation of the glycocalyx architecture via hyaluronidase treatment leads to considerable changes in cellular stiffness in both normal and cancerous cells, implying a link between the glycocalyx and the underlying actomyosin skeleton. Future studies will examine the in vitro effects of specific transmembrane mucins. Using overexpression and knockdown transfection models, the impact on cellular mechanics, as well as structural changes in the glycocalyx and actomyosin cortex, will be analyzed in pancreatic cancer cells to determine how these mucins effect cellular mechanics and by extension regulate tumorigenesis and metastasis.

Abstract
Objectives To report the person-to-staff transmission of COVID-19 with the implementation of a bubble concept that included testing, hygiene, distancing and monitoring strategies to mitigate risks. Methods A prospective case series included all staff on-site involved in the Football Club World Cup. The tournament was conducted within ‘bubbles’. All personnel travelling to the tournament were required to be in possession of a negative RT-PCR test within 72 hours of arrival and subjected to a testing schedule during the tournament. Each location was assigned a COVID-19 protocol enforcement officer to ensure adherence to regular testing, hygiene measures, physical distancing and daily symptom reporting (via ScribePro app). Results The study involved 70 recruited staff with a combined 1321 test days on the symptom checker app. The mean number of days completed on the symptom checker app was 18.87 days (range: 7–28). Of the five questions asked as part of the daily symptom checker, only one was answered positively (0.015%). This individual was isolated, assessed within 20 min and tested. The initial diagnosis was likely a non-COVID-19-related viral illness. Further testing returned three negative tests during the remainder of the tournament. Conclusions There was no person-to-staff transmission of COVID-19 during the tournament within our sample. The organisation of a sporting tournament during the COVID-19 pandemic is possible with risk mitigation strategies. These strategies include setting up a bubble with regular testing, hygiene measures, physical distancing and daily symptom reporting.

Match High-Speed Running Distances Are Often Suppressed After Return From Hamstring Strain Injury in Professional Footballers. Sports Health 2021; 13:290-295.

Abstract
BACKGROUND High-speed running is commonly implicated in the genesis of hamstring injury. The success of hamstring injury management is typically quantified by the duration of time loss or reinjury rate. These metrics do not consider any loss in performance after returning to play from hamstring injury. It is not known to what extent high-speed running is altered on return to play after such injury. HYPOTHESIS Match high-speed running distance will change after returning from hamstring injury. STUDY DESIGN Non-randomized cohort. LEVEL OF EVIDENCE Level 3. METHODS Match high-speed running distance in highest level professional football (soccer, Rugby League, Rugby Union, and Australian Rules) were examined for a minimum of 5 games prior and subsequent to hamstring strain injury for individual differences using a linear regression models approach. A total of 22 injuries in 15 players were available for analysis. RESULTS Preinjury cumulative high-speed running distances were strongly correlated for each individual (r2 = 0.92-1.0; P < 0.0001). Pre- and postinjury high-speed running data were available for a median of 15 matches (range, 6-15). Variance from the preinjury high-speed running distance was significantly less (P = 0.0005) than the post injury values suggesting a suppression of high-speed running distance after returning from injury. On return to play, 7 of the 15 players showed a sustained absolute reduction in preinjury high-speed running distance, 7 showed no change, and 1 player (only) showed an increase. Analysis of subsequent (second and third injury) return to play showed no differences to return from the index injury. CONCLUSION Return to play was not associated with return to high-speed running performance for nearly half of the players examined, although the same number showed no difference. Persisting deficits in match high-speed running may exist for many players after hamstring strain injury. CLINICAL RELEVANCE Returning to play does not mean returning to (high-speed running) performance for nearly half of the high-level professional football players examined in this study. This suggests that successful return to play metrics should be expanded from simple time taken and recurrence to include performance.

Abstract
BACKGROUND Hamstring injuries are common and account for considerable time lost to play in athletes. Platelet-rich plasma has potential as a means to accelerate healing of these injuries. PURPOSE (1) To present the evidence of platelet-rich plasma injection in the treatment of hamstring injuries, (2) evaluate the "best-case scenario" in dichotomous outcomes, and (3) evaluate the "worst-case scenario" in dichotomous outcomes. STUDY DESIGN Systematic review and meta-analysis. METHODS Two authors systematically reviewed the PubMed, Embase, and Cochrane Library databases according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, with any discrepancies resolved by mutual consensus. The level of evidence was assessed per the criteria of the Oxford Centre for Evidence-Based Medicine and the quality of evidence by the Coleman Methodology Score. Meta-analysis by fixed effects models was used if heterogeneity was low (I2 < 25%) and random effects models if heterogeneity was moderate to high (I2≥ 25%). P values <.05 were considered statistically significant. RESULTS A total of 10 studies were included with 207 hamstring injuries in the platelet-rich plasma group and 149 in the control group. Random-effects model for mean time to return to play that compared platelet-rich plasma + physical therapy to physical therapy alone non-significantly favored platelet-rich plasma + physical therapy (mean difference, -5.67 days). The fixed effects model for reinjury rates, which also compared platelet-rich plasma + physical therapy with physical therapy alone nonsignificantly favored platelet-rich plasma + physical therapy (risk ratio, 0.88). The best-case scenario fixed effects model for reinjury rates nonsignificantly favored platelet-rich plasma + physical therapy (risk ratio, 0.82). The worst-case scenario fixed effects model for reinjury rates nonsignificantly favored physical therapy alone (risk ratio, 1.13). The mean ± SD complication rate for either postinjection discomfort, pain, or sciatic nerve irritation was 5.2% ± 2.9% (range, 2.7% to 9.1%). CONCLUSION There has been statistically nonsignificant evidence to suggest that PRP injection ± PT reduced mean time to RTP or reinjury rates compared to no treatment or PT alone for hamstring injuries in a short-term follow-up. The complication profiles were favorable. Further studies of high quality and large cohorts are needed to better support or disprove the consensus of the systematic review and meta-analysis.

Abstract
Pancreatic cancer is a complex disease accounting for fibrotic tumors and an aggressive phenotype. Gemcitabine (GEM) is used as a standard therapy, which develops chemoresistance leading to poor patient outcome. We have recently developed a superparamagnetic iron oxide nanoparticle (SPION) formulation of curcumin (SP-CUR), which is a nontoxic, bioactive anti-inflammatory/anti-cancer agent for its enhanced delivery in tumors. In this study, we demonstrate that SP-CUR effectively delivers bioactive curcumin to pancreatic tumors, simultaneously enhances GEM uptake and its efficacy. Mechanistic revelations suggest that SP-CUR targets tumor microenvironment via suppression of sonic hedgehog (SHH) pathway and an oncogenic CXCR4/CXCL12 signaling axis that inhibits bidirectional tumor-stromal cells interaction. Increased GEM uptake was observed due to upregulation of the human nucleoside transporter genes (DCK, hCNT) and blocking ribonucleotide reductase subunits (RRM1/RRM2). Additionally, co-treatment of SP-CUR and GEM targets cancer stem cells by regulating pluripotency maintaining stemness factors (Nanog, Sox2, c-Myc and Oct-4), and restricting tumor sphere formation. In an orthotopic mouse model, an enhanced accumulation of SP-CUR was found in pancreas, which potentiated GEM to reduce tumor growth and metastasis. Analysis of tumor tissues suggest that the treatment inhibits tumor stroma (α-SMA, Desmin and Hyluronic Acid) and induces changes in cell stiffness, as measured via Atomic Force Microscopy. This was accompanied by alteration of key cellular proteins of SHH signaling such as SHH, Gli-1, Gli-2, Sufu, and NFĸB-65 as indicated by Immunoblotting and Immunohistochemistry. These results suggest that SP-CUR has a great potential for future clinical use in the management of pancreatic cancer.

Abstract
Neurodevelopmental insults leading to malformations of cortical development (MCD) are a common cause of psychiatric disorders, learning impairments and epilepsy. In the methylazoxymethanol (MAM) model of MCDs, animals have impairments in spatial cognition that, remarkably, are improved by post-weaning environmental enrichment (EE). To establish how EE impacts network-level mechanisms of spatial cognition, hippocampal in vivo single unit recordings were performed in freely moving animals in an open arena. We took a generalized linear modeling approach to extract fine spike timing (FST) characteristics and related these to place cell fidelity used as a surrogate of spatial cognition. We find that MAM disrupts FST and place-modulated rate coding in hippocampal CA1 and that EE improves many FST parameters towards normal. Moreover, FST parameters predict spatial coherence of neurons, suggesting that mechanisms determining altered FST are responsible for impaired cognition in MCDs. This suggests that FST parameters could represent a therapeutic target to improve cognition even in the context of a brain that develops with a structural abnormality.

Abstract
Abstract
On sustaining damage to their DNA, cells employ a sophisticated mechanism of detection and repair, termed the DNA damage response (DDR). As a critical component of the DDR and G2/M checkpoint, Chk1 kinase represents an attractive target for cancer therapy. We have utilized a structure-based drug design approach to identify and develop VER-250840, a novel, orally active inhibitor of the checkpoint kinase, Chk1. VER-250840 exhibited sub-nM potency against Chk1 kinase with exquisite selectivity over an extensive and diverse panel of kinases. In vitro, VER-250840 inhibited Chk1 autophosphorylation with an IC50 of 1.0 nM and increased the number of S-phase tumor cells staining positive for pan-nuclear γH2AX with an EC50 of 7 - 27 nM. Accumulated genomic DNA damage by Chk1 inhibition led to irreversible cell cycle arrest, inhibition of tumor cell proliferation, increased replication stress, and cell death in both 2D culture and multicellular tumor spheroids. In an in vivo A2058 tumor xenograft PD study, VER-250840 demonstrated rapid and sustained inhibition of Chk1 auto-phosphorylation within 30 minutes of oral administration. Doses of 10 mg/kg and higher PO resulted in greater than 90% inhibition of tumor pChk1 (S296) over 24 hours. In SKOV3 in vivo models, VER-250840 inhibited Chk1 auto-phosphorylation, modulated other biomarkers of replication stress and DNA damage, and exhibited moderate antitumor activity with minimal toxicity when administered orally on a 21-day once-daily schedule. Work is ongoing to further optimize in vivo efficacy. In conclusion, VER-250840 demonstrates potent and selective activity as a monotherapy both in vitro and in vivo. From these findings, further evaluation and optimization of this novel kinase inhibitor is justly merited.

Abstract
Abstract
Introduction: Pancreatic cancer (PanCa) is one of the most fatal cancers and is ranked as the fourth common cause of cancer-related deaths among both men and women in the US. The management of PanCa is exceptionally difficult due to the extremely poor response to available chemotherapeutic drugs. Microtubules are dynamic structures composed of α-β-tubulin heterodimers that are essential in cell division and are important targets for several clinical drugs (paclitaxel, docetaxel and vinblastine). However, clinical use of these tubulin-targeting drugs have toxicity and drug resistance issues in cancer patients. Thus, identification of more potent non-toxic inhibitors of β-tubulin is urgently required for cancer therapy purposes. In this study, we have identified a synthetic compound (ABI-231) which is a potent inhibitor of β-tubulin and evaluated its therapeutic efficacy against PanCa in vitro, and in vivo model systems.
Methods: ABI-231 ((2-(1H-indol-3-yl)-1H-imidazol-4-yl) (3, 4, 5-trimethoxyphenyl)) - methanone was synthesized and characterized in our department. Effect of ABI-231 on proliferation, migration and invasion of human PanCa cells (ASPC1, HPAFII, and PANC1) was performed by in vitro functional assays (MTS, wound healing, and Boyden chamber migrations). Effect of ABI-231 on the expression of β-tubulin isoforms was determined and compared with other clinical inhibitors of β-tubulin by Western blot, and qRT-PCR. Moreover, the effect of ABI-231 on the expression of β-tubulin III in PanCa cells was determined by confocal microscopy. Therapeutic efficacy of ABI-231 against PanCa was evaluated in an ectopic xenograft mouse model.
Results: ABI-231 treatment inhibited cell proliferation, invasion, migration and colony formation abilities of PanCa cells in a dose-dependent manner (1-100 nM) compared to vehicle treated group. Aberrant expression of β-tubulin III is involved in aggressiveness and drug resistance of various type of cancers including PanCa. ABI-231 effectively inhibited the protein levels and mRNA expression of total β-tubulin (TBB), TBB1, TBB2c, TBB3 and TBB4 in PanCa cells via destabilization. Our confocal microscopy results further showed inhibition of β-tubulin in ABI-231 treated PanCa cells. Upregulation of micro RNA 200c (miR-200c) has been shown to inhibit the expression of β-tubulin III in cancer cells. ABI-231 treatment of PanCa cells showed significant (p<0.01) induction of miR-200c as determined by qRT-PCR. ABI-231 administration (intra-tumoral; 50μg/mouse), three times/week significantly (p<0.01) inhibited the growth of ASPC1 cells derived xenograft tumors in athymic nude mice.
Conclusion: Taken together, our results suggest that ABI-231 is a potent β-tubulin inhibitor and chemotherapeutic agent which could be used for the treatment of pancreatic cancer.

Abstract
Veterinarians are encouraged to use evidence to inform their practice, but it is unknown what resources (e.g. journals, electronic sources) are accessed by them globally. Understanding the key places veterinarians seek information can inform where new clinically relevant evidence should most effectively be placed. An international survey was conducted to gain understanding of how veterinary information is accessed by veterinarians worldwide. There were 2137 useable responses to the questionnaire from veterinarians in 78 countries. The majority of respondents (n = 1835/2137, 85.9%) undertook clinical work and worked in a high income country (n = 1576/1762, 89.4%). Respondents heard about the survey via national veterinary organisations or regulatory bodies (31.5%), online veterinary forums and websites (22.7%), regional, discipline-based or international veterinary organisations (22.7%) or by direct invitation from the researchers or via friends, colleagues or social media (7.6%). Clinicians and non-clinicians reportedly used journals most commonly (65.8%, n = 1207/1835; 75.6%, n = 216/286) followed by electronic resources (58.7%, n = 1077/1835; 55.9%, n = 160/286), respectively. Respondents listed a total of 518 journals and 567 electronic sources that they read. Differences in veterinarian preference for resources in developed, and developing countries, were found. The nominated journals most read were the Journal of the American Veterinary Medical Association (12.7% of nominations) for clinicians and the Veterinary Record (5.7%) for non-clinicians. The most accessed electronic resource reported was the Veterinary Information Network (25.6%) for clinicians and PubMed (7.4%) for non-clinicians. In conclusion, a wide array of journals and electronic resources appear to be accessed by veterinarians worldwide. Veterinary organisations appear to play an important role in global communication and outreach to veterinarians and consideration should be given to how these channels could be best utilised for effective dissemination of key research findings.

Abstract
We evaluate the effect of epoxy surface structuring on the evaporation of water droplets containing Staphylococcus epidermidis (S. epidermidis). During evaporation, droplets with S. epidermidis cells yield to complex wetting patterns such as the zipping-wetting1-3 and the coffee-stain effects. Depending on the height of the microstructure, the wetting fronts propagate circularly or in a stepwise manner, leading to the formation of octagonal or square-shaped deposition patterns.4,5 We observed that the shape of the dried droplets has considerable influence on the local spatial distribution of S. epidermidis deposited between micropillars. These changes are attributed to an unexplored interplay between the zipping-wetting1 and the coffee-stain6 effects in polygonally shaped droplets containing S. epidermidis. Induced capillary flows during evaporation of S. epidermidis are modeled with polystyrene particles. Bacterial viability measurements for S. epidermidis show high viability of planktonic cells, but low biomass deposition on the microstructured surfaces. Our findings provide insights into design criteria for the development of microstructured surfaces on which bacterial propagation could be controlled, limiting the use of biocides.

Abstract
OBJECTIVE To determine whether people's beliefs about their illness, conceptualised by the common sense model (CSM), can prospectively predict adherence to self-management behaviours (including, attendance, medication, diet and exercise) in adults with acute and chronic physical illnesses. DESIGN AND MAIN OUTCOME MEASURES Electronic databases were searched in September 2014, for papers specifying the use of the 'CSM' in relation to 'self-management', 'rehabilitation' and 'adherence' in the context of physical illness. Six hundred abstracts emerged. Data from 52 relevant studies were extracted. Twenty-one studies were meta-analysed, using correlation coefficients in random effects models. The remainder were descriptively synthesised. RESULTS The effect sizes for individual illness belief domains and adherence to self-management behaviours ranged from .04 to .13, indicating very weak, predictive relationships. Further analysis revealed that predictive relationships did not differ by the: type of self-management behaviour; acute or chronic illness; or duration of follow-up. CONCLUSION Individual illness belief domains, outlined by the CSM, did not predict adherence to self-management behaviours in adults with physical illnesses. Prospective relationships, controlling for past behaviour, also did not emerge. Other factors, including patients' treatment beliefs and inter-relationships between individual illness beliefs domains, may have influenced potential associations with adherence to self-management behaviours.

Abstract
Access to the most up-to-date evidence is an important cornerstone for veterinarians attempting to practice in an evidence-based manner; therefore, an understanding of what and how information is accessed is vital. The aim of this study was to identify what resources the UK veterinary profession access and regard as most useful. Based on questionnaires received from veterinarians, the Veterinary Times was nominated as most often read journal or magazine by respondents (n=3572, 79 per cent). In Practice (n=3224, 82 per cent) and the Veterinary Record (n=165, 34 per cent) were seen as most useful by clinicians, and non-clinicians, respectively. Google was the most often nominated electronic resource by all respondents (n=3076, 71 per cent), with Google (n=459, 23 per cent) and PubMed (n=60, 17 per cent) seen as most useful by clinicians and non-clinicians, respectively. The abstract and conclusion sections were the most read parts of scientific manuscripts nominated by all respondents. When looking for assistance with difficult cases, colleagues were the common information choice for clinicians. Different sections of the veterinary profession access information, and deem resources useful, in different ways. Access to good quality evidence is important for the practice of evidence-based veterinary medicine, and therefore, researchers should think about disseminating their findings in a targeted way for optimal use by the profession.

Abstract
OBJECTIVE The long-term efficacy and safety of responsive direct neurostimulation was assessed in adults with medically refractory partial onset seizures. METHODS All participants were treated with a cranially implanted responsive neurostimulator that delivers stimulation to 1 or 2 seizure foci via chronically implanted electrodes when specific electrocorticographic patterns are detected (RNS System). Participants had completed a 2-year primarily open-label safety study (n = 65) or a 2-year randomized blinded controlled safety and efficacy study (n = 191); 230 participants transitioned into an ongoing 7-year study to assess safety and efficacy. RESULTS The average participant was 34 (±11.4) years old with epilepsy for 19.6 (±11.4) years. The median preimplant frequency of disabling partial or generalized tonic-clonic seizures was 10.2 seizures a month. The median percent seizure reduction in the randomized blinded controlled trial was 44% at 1 year and 53% at 2 years (p < 0.0001, generalized estimating equation) and ranged from 48% to 66% over postimplant years 3 through 6 in the long-term study. Improvements in quality of life were maintained (p < 0.05). The most common serious device-related adverse events over the mean 5.4 years of follow-up were implant site infection (9.0%) involving soft tissue and neurostimulator explantation (4.7%). CONCLUSIONS The RNS System is the first direct brain responsive neurostimulator. Acute and sustained efficacy and safety were demonstrated in adults with medically refractory partial onset seizures arising from 1 or 2 foci over a mean follow-up of 5.4 years. This experience supports the RNS System as a treatment option for refractory partial seizures. CLASSIFICATION OF EVIDENCE This study provides Class IV evidence that for adults with medically refractory partial onset seizures, responsive direct cortical stimulation reduces seizures and improves quality of life over a mean follow-up of 5.4 years.

Abstract
BACKGROUND Positron emission tomography and post-mortem studies of the number of somatodendritic 5-hydroxytryptamine(1A) (5-HT(1A)) autoreceptors in raphé nuclei have found both increases and decreases in depression. However, recent genetic studies suggest they may be increased in number and/or function. The current study examined the effect of buspirone on the electroencephalographic (EEG) centroid frequency, a putative index of somatodendritic 5-HT(1A) receptor functional status, in a cohort of medication-free depressed patients and controls. METHOD A total of 15 depressed patients (nine male) and intelligence quotient (IQ)-, gender- and age-matched healthy controls had resting EEG recorded from 29 scalp electrodes prior to and 30, 60 and 90 min after oral buspirone (30 mg) administration. The effect of buspirone on somatodendritic 5-HT(1A) receptors was assessed by calculating the EEG centroid frequency between 6 and 10.5 Hz. The effect of buspirone on postsynaptic 5-HT(1A) receptors was assessed by measuring plasma growth hormone, prolactin and cortisol concentrations. RESULTS Analysis of variance revealed a significantly greater effect of buspirone on the EEG centroid frequency in patients compared with controls (F1,28 = 6.55, p = 0.016). There was no significant difference in the neuroendocrine responses between the two groups. CONCLUSIONS These findings are consistent with an increase in the functional status of somatodendritic, but not postsynaptic, 5-HT1A autoreceptors, in medication-free depressed patients in line with hypotheses based on genetic data. This increase in functional status would be hypothesized to lead to an increase in serotonergic negative feedback, and hence decreased release of 5-HT at raphé projection sites, in depressed patients.

Abstract
The practice of evidence-based veterinary medicine involves the utilisation of scientific evidence for clinical decision making. To enable this, research topics pertinent to clinical practice need to be identified, and veterinary clinicians are best placed to do this. The main aim of this study was to describe the veterinary population, the common species and conditions veterinary clinicians nominated they saw in practice and how much information clinicians perceived was available in the literature for these. A questionnaire was distributed to all Royal College of Veterinary Surgeons registered veterinarians agreeing to be contacted for research purposes (n=14,532). A useable response rate of 33 per cent (4842/14,532) was achieved. The most commonly seen species reported by vets were dogs, cats and rabbits followed by equines and cattle. Overall, skin conditions were most commonly mentioned for small animals, musculoskeletal conditions for equines and reproduction conditions for production animals. Veterinary clinicians perceived there was a higher level of information available in the literature for conditions in dogs, cattle and equines and lower levels for rabbits and guinea pigs. The results from this study can be used to help define the research needs of the profession to aid the incorporation of evidence in veterinary practice.

Abstract
Reducing the lattice parameter of a Sn–metal surface alloy below the O–O separation of ice disrupts the flat wetting layer, causing the first layer to buckle and instead form ice clusters.
