Abstract
ABSTRACT Brennan, A, Murray, A, Coughlan, D, Mountjoy, M, Wells, J, Ehlert, A, Xu, J, Broadie, M, Turner, A, and Bishop, C. Validity and reliability of the FlightScope Mevo+ launch monitor for assessing golf performance. J Strength Cond Res 38(4): e174-e181, 2024-The purpose of this study was to (a) assess the validity of the FlightScope Mevo+ against the TrackMan 4 and (b) determine the within-session reliability of both launch monitor systems when using a driver and a 6-iron. Twenty-nine youth golfers, with a minimum of 3 years of playing experience, volunteered for this study. All golfers completed 10 shots with a 6-iron and a driver, with 8 metrics concurrently monitored from both launch monitor systems in an indoor biomechanics laboratory. For both clubs, Pearson's r values ranged from small to near perfect ( r range = 0.254-0.985), with the strongest relationships evident for clubhead speed (CHS) and ball speed ( r ≥ 0.92). Bland-Altman plots showed almost perfect levels of agreement between devices for smash factor (mean bias ≤-0.016; 95% CI: -0.112, 0.079), whereas the poorest levels of agreement was for spin rate (mean bias ≤1,238; 95% CI: -2,628, 5,103). From a reliability standpoint, the TrackMan showed intraclass correlation coefficients (ICCs) ranging from moderate to excellent (ICC = 0.60-0.99) and coefficient of variation (CV) values ranged from good to poor (CV = 1.31-230.22%). For the Mevo+ device, ICC data ranged from poor to excellent (ICC = -0.22 to 0.99) and CV values ranged from good to poor (CV = 1.46-72.70%). Importantly, both devices showed similar trends, with the strongest reliability consistently evident for CHS, ball speed, carry distance, and smash factor. Finally, statistically significant differences ( p < 0.05) were evident between devices for spin rate (driver: d = 1.27; 6-iron: d = 0.90), launch angle (driver: d = 0.54), and attack angle (driver: d = -0.51). Collectively, these findings suggest that the FlightScope Mevo+ launch monitor is both valid and reliable when monitoring CHS, ball speed, carry distance, and smash factor. However, additional variables such as spin rate, launch angle, attack angle, and spin axis exhibit substantially greater variation compared with the TrackMan 4, suggesting that practitioners may wish to be cautious when providing golfers with feedback relating to these metrics.

Abstract
OBJECTIVE To assess health problems and training environment of female golfers participating in the 2022 World Amateur Team Championships (WATC) and to compare golfers (a) with and without health problems prior the WATC and (b) living and training in countries ranking in the upper versus lower 50% of the team results at the 2022 WATC. DESIGN Cross-sectional cohort study using an anonymous questionnaire. SETTING International Golf Federation WATC. PARTICIPANTS One hundred sixty-two female golfers from 56 countries. INTERVENTIONS N/A. MAIN OUTCOME MEASURES Golfers' answers on the presence and characteristics of health problems, their training environment, and to the Oslo Sport Trauma Research Centre Questionnaire. RESULTS Almost all golfers (n = 162; 96%) answered the questionnaire. In the 4 weeks before the WATC, 101 golfers (63.1%) experienced 186 musculoskeletal complaints, mainly at the lumbar spine/lower back, wrist, or shoulder. Just half of the golfers (50.6%) performed injury prevention exercises always or often. More than a third (37.4%) of the golfers reported illness complaints and 32.5% mental health problems in the 4 weeks preceding the WATC. General anxiety, performance anxiety, and low mood/depression were the most frequent mental health problems. Golfers with injury complaints rated their daily training environment poorer. Golfers ranking in the lower 50% at the WATC had significantly less support staff, rated their training environment poorer, and had a higher prevalence of illness complaints and mental health problems. CONCLUSIONS Effective illness and injury prevention programs should be implemented and better access to education and health support in the daily training environment provided.

Abstract
BACKGROUND Historically, golf does not have a strong tradition of fitness testing and physical training. However, in recent years, both players and practitioners have started to recognise the value of a fitter and healthier body, owing to its potential positive impacts on performance, namely clubhead speed (CHS). OBJECTIVE The aim of this meta-analysis was to examine the associations between CHS (as measured using a driver) and a variety of physical characteristics. METHODS A systematic literature search with meta-analysis was conducted using Medline, SPORTDiscus, CINAHL and PubMed databases. Inclusion criteria required studies to have (1) determined the association between physical characteristics assessed in at least one physical test and CHS, (2) included golfers of any skill level but they had to be free from injury and (3) been peer-reviewed and published in the English language. Methodological quality was assessed using a modified version of the Downs and Black Quality Index tool and heterogeneity assessed via the Q statistic and I2. To provide summary effects for each of the physical characteristics and their associations with CHS, a random effects model was used where z-transformed r values (i.e. zr) were computed to enable effect size pooling within the meta-analysis. RESULTS Of the 3039 studies initially identified, 20 were included in the final analysis. CHS was significantly associated with lower body strength (zr = 0.47 [95% confidence intervals {CI} 0.24-0.69]), upper body strength (zr = 0.48 [95% CI 0.28-0.68]), jump displacement (zr = 0.53 [95% CI 0.28-0.78]), jump impulse (zr = 0.82 [95% CI 0.63-1.02]), jumping peak power (zr = 0.66 [95% CI 0.53-0.79]), upper body explosive strength (zr = 0.67 [95% CI 0.53-0.80]), anthropometry (zr = 0.43 [95% CI 0.29-0.58]) and muscle capacity (zr = 0.17 [95% CI 0.04-0.31]), but not flexibility (zr = - 0.04 [95% CI - 0.33 to 0.26]) or balance (zr = - 0.06 [95% CI - 0.46 to 0.34]). CONCLUSIONS The findings from this meta-analysis highlight a range of physical characteristics are associated with CHS. Whilst significant associations ranged from trivial to large, noteworthy information is that jump impulse produced the strongest association, upper body explosive strength showed noticeably larger associations than upper body strength, and flexibility was not significant. These findings can be used to ensure practitioners prioritise appropriate fitness testing protocols for golfers.

Abstract
ABSTRACT Robinson, L, Murray, A, Ehlert, A, Wells, J, Jarvis, P, Turner, A, Glover, D, Coughlan, D, Hembrough, R, and Bishop, C. Effects of physical training and associations between physical performance characteristics and golf performance in female players: A systematic review with meta-analysis. J Strength Cond Res 37(12): e646-e655, 2023-The aims of this systematic review were to assess the association between physical performance and measures of golf performance, and the effects of physical training on measures of golf performance, in female golfers. A systematic literature search was conducted in PubMed, SPORTDiscus, Medline, and CINAHL. Inclusion criteria required studies to (a) have conducted a physical training intervention of any duration in female players and determine the effects on measures of golf performance, (b) determine the association between physical performance in at least one test and golf performance in female players, and (c) be peer-reviewed and published in English language. Methodological quality was assessed using a modified version of the Downs and Black Quality Index tool, and heterogeneity was examined through the Q statistic and I2 . Pooled effect sizes were calculated using standardized mean differences (SMDs) (with 95% confidence interval [CI]s) within a random-effects model, with Egger's regression test used to assess small study bias (inclusive of publication bias). Of the 2,378 articles screened, only 9 were included in the final review, with 3 of these being associative by design and 6 being training interventions. From an associative standpoint, clubhead speed (CHS) was reported in all 3 studies and was associated with measures of strength ( r = 0.54), lower-body power ( r = 0.60), upper-body power ( r = 0.56-0.57), and flexibility ( r = 0.52-0.71). When assessing the effects of physical training interventions, CHS was again the most commonly reported golf outcome measure ( n = 5). The random-effect model indicated that CHS significantly improves within each training group following training interventions (SMD = 0.73 [95% CIs: 0.32-1.14], Z = 3.50, p < 0.001), with trivial heterogeneity ( I2 = 0.00%, Q = 0.18; p = 0.9963) and no prevalence of small study bias depicted through the Egger's regression test ( z = -0.28, p = 0.78). From the available research, it seems that CHS can be positively affected from strength, power, and flexibility training interventions. From an associative standpoint, only 3 studies have been conducted solely in female players, with one showcasing questionable methodology. Future research should aim to carefully select test measures which better represent the physical capacities needed for the sport when determining the effects of and relationships with golf performance.

Abstract
BACKGROUND The physical demands of golf caddying, including walking while carrying a golf bag, may potentially affect body composition, and markers of metabolic, cardiovascular, and musculoskeletal health. Therefore, this study examined the impact of 24 weeks of caddying on physical health in middle-older aged males. METHODS Eleven full-time experienced male caddies (age: 59 [8] y; caddying experience: 14 [12] y) were recruited from a local golf course. The following were assessed at preseason and after 24 weeks of caddying (March-September 2022): body composition, heart rate, blood pressure, blood lipids, and performance tests (static and dynamic balance, strength, and submaximal fitness). Physical activity (PA) levels were assessed at preseason and at the mid-point of the caddying season. Across the caddying season, participants completed a monthly average of 24.0 (3.8) rounds. RESULTS Following the caddying season, improvements in static balance (Δ = 13.5 s), dynamic balance (Δ = -1.8 s), and lower back absolute strength (Δ = 112.8 N), and muscle quality (Δ = 2.0 N·kg-1) were observed (all P < .05). Additionally, blood lipids, including total cholesterol (Δ = -0.6 mmol·L-1), high-density lipoprotein cholesterol (Δ = 0.1 mmol·L-1), low-density lipoprotein cholesterol (Δ = -0.6 mmol·L-1) (all P < .05), and body composition, including body mass (Δ = -2.7 kg), fat mass (Δ = -1.9 kg), fat percentage (Δ = -1.4%), fat-to-muscle ratio (Δ = -0.03), and body mass index (Δ = -0.9 kg·m-2) (all P < .05) improved. Caddying did not offer beneficial changes to cardiovascular variables or cardiorespiratory fitness (P > .05), while coronary heart disease risk score decreased (Δ = -3.3%) (P < .05). In relation to PA, light- (Δ = 145 min) and moderate-intensity (Δ = 71 min) PA, moderate to vigorous PA (Δ = 73 min), and total PA (Δ = 218 min) between preseason and the mid-point of the caddying season increased, while sedentary time (Δ = -172 min) decreased (all P < .05). CONCLUSION Golf caddying can provide several physical health benefits such as improvements in various markers of cardiometabolic health, lower back absolute strength, and static and dynamic balance. The physical health improvements that caddying offers is likely contributed to by increased PA volume and intensity through walking on the golf course. Therefore, caddying may represent a feasible model for increasing PA volume and intensity and achieve physical health-related benefits.

Abstract
This study aims to ascertain an in-depth understanding of current practices and perceptions of S&C training in high-level amateur female golfers. A cross-sectional, explorative survey study was constructed which asked questions relating to four key areas: i) general participant information, ii) current strength and conditioning (S&C) practices, iii) the perceived influence of S&C training on golf performance, and iv) knowledge and awareness of S&C. Results showed that the majority of female players had participated in some form of S&C training in the past, with the majority believing that clubhead speed and carry distance were the primary golfing metrics which could be positively impacted. More specifically, 91-97% of the players "Strongly agreed" or "Agreed" that the key physical characteristics for golf were strength and power for the lower and upper body, and flexibility. Interestingly, 58% of the players believed that S&C training should mimic the movement of the golf swing, which based off current evidence, is not how drive metrics and ultimately shots gained, can be maximised. This survey study provides useful information relating to the practices and perceptions of S&C training in high-level female amateur players and areas where education may be able to further advance player understanding of physical preparation.

Abstract
INTRODUCTION The transforaminal lumbar interbody fusion (TLIF) is among the most utilized methods for the surgical treatment of lumbar degenerative disc disease. The TLIF has advanced significantly with several iterative changes since its inception in the early 1980s, with the advent of several generations of interbody types, shapes, and materials. Steerable curvilinear interbodies are among the most recent innovations in this space and may offer biomechanical advantages, namely in preservation of lumbar and segmental lordosis. While radiographic parameters have been investigated for other cage shapes and lumbar interbody fusion techniques, no study has investigated postoperative radiographic outcomes specific to TLIFs done with curvilinear interbodies. METHODS This study is a retrospective review of TLIFs performed with curvilinear interbodies between 2019 and 2022 at a single institution. Upright radiographs were obtained preoperatively and at several timepoints postoperatively. Radiographic variables including interspace height and segmental lordosis were collected. RESULTS 26 surgeries with 32 curvilinear interbodies were performed across 3 years. There was significant increase in segmental lordosis at the L4-L5 (p = 0.0183) and L5-S1 levels (p = 0.004) as well as interspace height postoperatively at levels L3-L4 (p = 0.011) and L4-L5 (p = 0.002). Pain as measured with the numeric rating scale significantly improved in the overall cohort postoperatively (p<0.001). CONCLUSIONS TLIF with curvilinear interbody placement increases segmental lordosis and interspace height at the L4-L5 and L5-S1 levels, and increased interspace height at the L3-L4 and L4-L5 levels. Further investigation into additional radiographic parameters is warranted and expanded cohort size would benefit deeper analysis of other spinal levels. IMPLICATIONS FOR PRACTICE As an increasing number of cage designs and materials are brought to market, studies such as this allow for better understanding of cage specific outcomes allowing for better informed device selection.

Abstract
The aims of the present study were to: 1) investigate the within and between-session reliability of the Trackman 4 launch monitor system, and 2) determine the inter-relationships of some of these commonly used metrics. Golfers attended two test sessions at an indoor golf academy and performed 10 shots using their own driver. Results showed excellent within and between-session reliability for CHS (ICC = 0.99; SEM = 1.64-1.67 mph), ball speed (ICC = 0.97-0.99; SEM = 2.46-4.42 mph) and carry distance (ICC = 0.91-0.97; SEM = 7.80-14.21 mph). In contrast, spin rate showed the worst reliability (ICC = 0.02-0.60; SEM = 240.93-454.62 º/s) and also exhibited significant differences between test sessions (g = -0.41; p < 0.05), as did smash factor (g = 0.47; p < 0.05) and dynamic loft (g = -0.21; p < 0.05). Near perfect associations were evident in both test sessions between CHS and ball speed (r = 0.98-0.99), CHS and carry distance (r = 0.94-0.95), ball speed and carry distance (r = 0.97-0.98), and launch angle and dynamic loft (r = 0.98-0.99). Collectively, CHS, ball speed and carry distance serve as the most consistently reliable metrics making them excellent choices for practitioners working with golfers.

Abstract
Introduction The global burden of age-related cognitive decline is increasing, with the number of people aged 60 and over expected to double by 2050. This study compares the acute effects of age-appropriate cognitively demanding aerobic exercises involving walking, on cognitive functions and exerkine responses such as brain-derived neurotrophic factor (BDNF) and cathepsin B (CTSB) in older, healthy adults. Methods/design Healthy older golfers (n=25, 16 male and 9 female, 69±4 years) were enrolled in a 5-day randomised cross-over study and completed three different exercise trials (18-hole golf round, 6 km Nordic walking, 6 km walking) in a real-life environment, in random order and at a self-selected pace. Differences in cognition (the Trail-Making Test (TMT) AB) and exerkines (BDNF and CTSB) were analysed within groups using the Wilcoxon signed-rank test and between groups using the Kruskal-Wallis test. Results All exercise types resulted in a significant decrease in the TMT A-test (p<0.05; golf: -4.43±1.5 s, Nordic walking: -4.63±1.6 s, walking: -6.75±2.26 s), where Nordic walking and walking demonstrated a decrease in the TMT B-test (p<0.05; Nordic walking: -9.62±7.2 s, walking: -7.55±3.2 s). In addition, all exercise types produced significant decreases in the TMT AB test scores (p<0.05), and Nordic walking (p=0.035) showed decreases in the TMTB-TMTA-test. There were no immediate postexercise changes in the levels of BDNF or CTSB. Conclusion Acute bouts of golf, Nordic walking and walking improved cognitive functions irrespective of exerkines in healthy older adults. In addition, Nordic walking and walking in general enhanced executive functions. No significant effects were seen on the levels of BDNF and CTSB. Trial registration number ISRCTN10007294.

Abstract
PURPOSE/OBJECTIVE(S) To determine the effect of delays in radiation treatment preparation task timeliness on reported safety events. MATERIALS/METHODS For 2022, all patients treated at four community-based radiation oncology clinics were included for analysis. Safety reports which occurred during treatment preparation tasks (i.e., between CT simulation and the first treatment) were included for this analysis. Patients with a reported safety event were the report cohort and those without were the control cohort. Treatment preparation tasks are completed sequentially and included contouring, treatment planning, Radiation Oncologist review, Medical Physicist review, Therapist quality check. At baseline, each task was scheduled a standard interval for completion based on treatment technique. The time taken to complete each task was captured using ARIA v16.0 Care Path module (Varian Medical Systems, Palo Alto, CA) and extracted through database query. For each task, two metrics were quantified: Task (1) Completion Timeliness: the time (hours) to complete each task, relative to the time allocated to each task. A negative value indicated more time taken than scheduled. (2) Overall Timeliness: specific task timeliness (hours) relative to overall timeliness for the whole Care Path. A negative value indicated the tasks were behind schedule. A student's t-test with an alpha of 0.05 was used to indicate significance. RESULTS Over the study period, 66 courses had a reported treatment preparation safety event (report) and 2690 did not (control). Techniques include 54% and 56% 3DCRT, 35% and 35% IMRT, 3% and 3% SRS, and 6% and 8% SBRT, for the report and control groups, respectively. Disease sites include breast, GU, GI, head and neck, CNS, thoracic, skin, secondary, gynecological, sarcoma, and heme. Table 1 displays the timeliness for each of the five tasks. Of the courses with safety events, overall timeliness was significantly behind the control group from the in contouring, treatment planning, Radiation Oncologist review, and Medical Physicist review. Courses with safety events took significantly more time than scheduled early in treatment preparation with a significant increase at treatment planning and significantly less time towards the end with the therapist quality check. CONCLUSION Patient courses with reported safety events had significantly longer treatment planning times, and as a result inadequate time to perform each downstream pre-treatment activity. The implication of this analysis is that a flag could be created to indicate risk of a safety event early in the treatment preparation process.

Abstract
A modular, multi-purpose, and cost-effective electrochemical biosensor based on a five-stranded four-way junction (5S-4WJ) system was developed for SARS-CoV-2 (genes S and N) and Influenza A virus (gene M) detection. The 5S-4WJ structure consists of an electrode-immobilized universal stem-loop (USL) strand, two auxiliary DNA strands, and a universal methylene blue redox strand (UMeB). This design allows for the detection of specific nucleic acid sequences using square wave voltammetry (SWV). The sequence-specific auxiliary DNA strands (m and f) ensure selectivity of the biosensor for target recognition utilizing the same USL and UMeB components. An important feature of this biosensor is the ability to reuse the USL-modified electrodes to detect the same or alternative targets in new samples. This is accomplished by a simple procedure involving rinsing the electrodes with water to disrupt the 5S-4WJ structure and subsequent re-hybridization of the USL strand with the appropriate set of strands for a new analysis. The biosensor exhibited minimal loss in signal after rehybridization, demonstrating its potential as a viable multiplex assay for both current and future pathogens, with a low limit of quantification (LOQ) of as low as 17 pM.

Abstract
This study assessed the lead and trail arm peak and average extensor carpi ulnaris (ECU) muscle activity in association with tri-planar angular velocities of the lead and trail wrists during the golf swing. Fifteen sub-elite, male right-handed golfers (Mage = 34.7 years ±13.3, Mhandicap = 1.5 ± 2.2) were recruited to execute five shots each with their pitching wedge, 7-iron and driver clubs in an indoor golf simulator. Surface electromyography (EMG) sensors were placed over the ECU muscle belly and inertial measurement unit sensors were placed bi-laterally on the distal forearm and dorsum of the hand. There was a statistically greater recruitment of the trail ECU muscle during the downswing (p < 0.001) for all clubs. The lead ECU muscle was recruited more during the backswing (p < 0.001) and follow through (p < 0.024) phases. There were statistically different tri-planar movement patterns between the lead and trail wrist throughout all three phases of the golf swing. No significant relationships were found between downswing EMG data and clubhead kinematics at impact. In conclusion, differing wrist kinematics and associated muscle activity may contribute to the asymmetrical injury pattern seen clinically.

Abstract
BACKGROUND Despite evidence that structured goals of care conversations (GoCCs) and documentation of life-sustaining treatment (LST) preferences improve the delivery of goal-concordant care for seriously ill patients, rates of completion remain low among nursing home residents. The Preferences Elicited and Respected for Seriously Ill Veterans through Enhanced Decision-Making (PERSIVED) program aims to improve the consistent documentation of LST preferences among Veterans receiving care in veterans affairs (VA)-paid community nursing homes (CNH); however, the barriers and facilitators of completing and documenting GoCCs in this unique context of care have not been described. METHODS We conducted semi-structured, qualitative interviews with key stakeholders of the VA CNH programs located at six VA Medical Centers between July 2021 and July 2022. With a rapid approach to analysis, interview transcripts were reduced into memo templates using the Tailored Implementation for Chronic Disease Checklist and coded and analyzed using qualitative data analysis software. RESULTS The 40 participants consisted of nurses (n = 13), social workers (n = 25), and VA physicians (n = 2). Most participants felt confident about conducting GoCC; however, several barriers were identified. At the staff level, our results indicated inconsistent completion of GoCC and documentation due to a lack of training, confusion about roles and responsibilities, and challenging communication within the VA as well as with CNH. At the organizational level, there was a lack of standardization across sites for how LST preferences were documented. At the patient level, we found key barriers related to patient and family readiness and issues finding surrogate decision makers. While COVID-19 brought end-of-life issues to the forefront, lockdowns hindered communication about the goals of care. CONCLUSION Findings from this pre-implementation evaluation revealed multi-level barriers in conducting and documenting GoCCs with Veterans receiving VA-paid CNH care, as well as several facilitators that can be used to inform strategies for improvement.

Abstract
Background and Aims The COVID-19 pandemic was associated with reduced physical activity and increased sedentary behavior. Golf is a health-enhancing outdoor exercise and is associated with low risk of viral transmission. The purpose of this study was to describe the seasonal differences in physical activity and quality of life during the first wave of COVID-19 pandemic in 2020 in Finnish older golfers. Methods Older golfers (n = 325) from eight golf clubs retrospectively responded to a questionnaire in summer 2020 on their physical activity and golf activity in winter 2019/20 (pre-COVID-19 winter season) and summer season 2020. In addition, they reported their quality of life after the first wave of pandemic in summer 2020. To evaluate the seasonal differences in physical activity, life quality and its association with golf activity, the data were analyzed using the Mann-Whitney U test, Wilcoxon signed-rank test, Spearman's correlation test, and linear regression analysis. Results Despite COVID-19 restrictions, golfers' physical activity increased by 24% (p < 0.001) during the COVID-19 restrictions in the summer of 2020. Moderate physical activity increased by 37% (p < 0.001), walking activity increased by 26% (p < 0.001), and sitting decreased by 21% (p < 0.001) compared with the pre-COVID-19 winter season. The full 18-hole golf round activity was positively associated with moderate physical activity both in the summer and winter season, and with walking in the summer season. Over 90% of golfers reported good quality of life during the 2020 summer restrictions. Conclusion In contrast to physical activity levels generally decreasing during the first wave of pandemic, physical activity levels in Finnish golfers increased, and these golfers reported a good quality of life. Golf can provide health enhancing physical activity and older golfers seems to be physically active throughout the year.

Abstract
PURPOSE To assess objective strain and subjective muscle soreness in "Bigs" (offensive and defensive line), "Combos" (tight ends, quarterbacks, line backers, and running backs), and "Skills" (wide receivers and defensive backs) in American college football players during off-season, fall camp, and in-season phases. METHODS Twenty-three male players were assessed once weekly (3-wk off-season, 4-wk fall camp, and 3-wk in-season) for hydroperoxides (free oxygen radical test [FORT]), antioxidant capacity (free oxygen radical defense test [FORD]), oxidative stress index (OSI), countermovement-jump flight time, Reactive Strength Index (RSI) modified, and subjective soreness. Linear mixed models analyzed the effect of a 2-within-subject-SD change between predictor and dependent variables. RESULTS Compared to fall camp and in-season phases, off-season FORT (P ≤ .001 and <.001), FORD (P ≤ .001 and <.001), OSI (P ≤ .001 and <.001), flight time (P ≤ .001 and <.001), RSI modified (P ≤ .001 and <.001), and soreness (P ≤ .001 and <.001) were higher for "Bigs," whereas FORT (P ≤ .001 and <.001) and OSI (P = .02 and <.001) were lower for "Combos." FORT was higher for "Bigs" compared to "Combos" in all phases (P ≤ .001, .02, and .01). FORD was higher for "Skills" compared with "Bigs" in off-season (P = .02) and "Combos" in-season (P = .01). OSI was higher for "Bigs" compared with "Combos" (P ≤ .001) and "Skills" (P = .01) during off-season and to "Combos" in-season (P ≤ .001). Flight time was higher for "Skills" in fall camp compared with "Bigs" (P = .04) and to "Combos" in-season (P = .01). RSI modified was higher for "Skills" during off-season compared with "Bigs" (P = .02) and "Combos" during fall camp (P = .03), and in-season (P = .03). CONCLUSION Off-season American college football training resulted in higher objective strain and subjective muscle soreness in "Bigs" compared with fall camp and during in-season compared with "Combos" and "Skills" players.

Abstract
BACKGROUND Tennis is a multidirectional high-intensity intermittent sport for male and female individuals played across multiple surfaces. Although several studies have attempted to characterise the physical demands of tennis, a meta-analysis is still lacking. OBJECTIVE We aimed to describe and synthesise the physical demands of tennis across the different court surfaces, performance levels and sexes. METHODS PubMed, Embase, CINAHL and SPORTDiscus were searched from inception to 19 April, 2022. A backward citation search was conducted for included articles using Scopus. The PECOS framework was used to formulate eligibility criteria. POPULATION tennis players of regional, national or international playing levels (juniors and adults). EXPOSURE singles match play. Comparison: sex (male/female), court surface (hard, clay, grass). OUTCOME duration of play, on-court movement and stroke performance. STUDY DESIGN cross-sectional, longitudinal. Pooled means or mean differences with 95% confidence intervals were calculated. A random-effects meta-analysis with robust variance estimation was performed. The measures of heterogeneity were Cochrane Q and 95% prediction intervals. Subgroup analysis was used for different court surfaces. RESULTS The literature search generated 7736 references; 64 articles were included for qualitative and 42 for quantitative review. Mean [95% confidence interval] rally duration, strokes per rally and effective playing time on all surfaces were 5.5 s [4.9, 6.3], 4.1 [3.4, 5.0] and 18.6% [15.8, 21.7] for international male players and 6.4 s [5.4, 7.6], 3.9 [2.4, 6.2] and 20% [17.3, 23.3] for international female players. Mean running distances per point, set and match were 9.6 m [7.6, 12.2], 607 m [443, 832] and 2292 m [1767, 2973] (best-of-5) for international male players and 8.2 m [4.4, 15.2], 574 m [373, 883] and 1249 m [767, 2035] for international female players. Mean first- and second-serve speeds were 182 km·h-1 [178, 187] and 149 km·h-1 [135, 164] for international male players and 156 km·h-1 95% confidence interval [151, 161] and 134 km·h-1 [107, 168] for international female players. CONCLUSIONS The findings from this study provide a comprehensive summary of the physical demands of tennis. These results may guide tennis-specific training programmes. We recommend more consistent measuring and reporting of data to enable future meta-analysts to pool meaningful data. CLINICAL TRIAL REGISTRATION The protocol for this systematic review was registered a priori at the Open Science Framework (Registration DOI https://doi.org/10.17605/OSF.IO/MDWFY ).

Abstract
ObjectivesThe primary aim was to describe the characteristics and prevalence of musculoskeletal complaints of a large group of non-professional golfers. Secondary aims were to compare golfers different in (A) skill-level, (B) presence of low back pain (LBP) and (C) performance of prevention exercises.MethodsA sample of 1170 male golfers (mean age 54.98, SD=13.3) were surveyed online on personal and golf-specific characteristics, medical history and complaints in the preceding 7 days. Subgroups (A) with different golfing handicap (0 to 5, >5 to 10, >10), (B) with and without LBP and (C) who performed versus did not perform injury prevention exercises were compared using analysis of variance and χ2test.ResultsThe prevalence and severity of musculoskeletal complaints was similar in everyday life and when playing golf. More than one-third of the golfers (n=436; 37.3%) reported LBP in the preceding 7 days, while other frequently affected body parts were the shoulder and knee. Golfers with different skill level differed in age and most golf-related characteristics but not in prevalence and severity of musculoskeletal complaints. Golfers with and without LBP were similar in almost all variables. Golfers who performed prevention exercises (n=371; 27.1%) were older and had a higher prevalence of complaints.ConclusionThe prevalence and severity of musculoskeletal complaints in golfers were similar to the wider population. It seems that injury prevention exercises were implemented after injury, rather than as primary prevention. Prospective studies looking at the epidemiology of injury, risk factors and interventions are required.

Abstract
Promoters and the noncoding sequences that drive their function are fundamental aspects of genes that are critical to their regulation. The transcription preinitiation complex binds and assembles on promoters where it facilitates transcription. The transcription start site (TSS) is located downstream of the promoter sequence and is defined as the location in the genome where polymerase begins transcribing DNA into RNA. Knowing the location of TSSs is useful for annotation of genes, identification of non-coding sequences important to gene regulation, detection of alternative TSSs, and understanding of 5' UTR content. Several existing techniques make it possible to accurately identify TSSs, but are often difficult to perform experimentally, require large amounts of input RNA, or are unable to identify a large number of TSSs from a single sample. Many of these protocols take advantage of template switching reverse transcriptases (TSRTs), which reliably place an adaptor at the 5' end of a first strand synthesis of cDNA. Here, we introduce a protocol that exploits TSRT activity combined with rolling circle amplification to identify TSSs with several unique advantages over existing methods. Sequence adaptors are placed on the 5' and 3' end of the full-length cDNA copy of a transcript. A splint compatible with those adaptors is then used to circularize the full-length cDNA. Linear DNA containing concatemers of the cDNA are generated using rolling circle amplification, and a sequencing library is formed by fragmenting the concatemers. This protocol is straightforward to execute, requiring limited bench time with relatively stable reagents. Using extremely low amounts of RNA input, this protocol produces large numbers of accurate, deduplicated TSSs genome wide. © 2023 The Authors. Current Protocols published by Wiley Periodicals LLC.

Abstract
Golf is a sport played around the globe, with an estimated 42.6 million people playing within the United Kingdom and United States of America alone. To date, there is limited data on the energy expenditure of golf. The present study assessed the activity energy expenditure (AEE) of 16 high-standard (handicap under 5) golfers who completed three rounds of competitive golf either carrying the golf bag (BC), using a manual push trolley (MT) or an electric trolley (ET) (Stewart Golf, Gloucester, UK). Prior to each round, participants were fitted with an Actiheart® accelerometer (Camntech, Fenstanton, UK) to estimate AEE, whilst ratings of perceived exertion (RPE) and enjoyment were collected following each round. Data were analysed using a one-way repeated measures ANOVA, with Hedges g effect sizes (ES) calculated. Mean (SD) AEE was 688 ± 213 kcal for BC, 756 ± 210 kcal for MT and 663 ± 218 kcal for ET (p = .05) although these differences were deemed small or less. The ET condition resulted in the lowest mean heart rate, moderate or very large from BC or MT, respectively. There were no significant differences in enjoyment although perceived exertion was lowest in the ET condition. In summary, we report meaningful differences in AEE between the three conditions (p = .05), with perceived exertion and maximum HR being lowest when using the electric trolley. Golf may be considered as an effective intervention to increase step count and improve physical activity levels across the general population regardless of transportation methods of clubs.

Abstract
INTRODUCTION There has been much debate recently on the participation of transgender and gender-diverse (TGD) athletes in sport, particularly in relation to fairness, safety and inclusion. The 2021 IOC Framework on Fairness, Inclusion and Non-discrimination acknowledges the central role that eligibility criteria play in ensuring fairness, particularly in the female category, and states that athletes should not be excluded solely on the basis of their TGD identity. AIMS To identify policies that address TGD athlete participation in the 15 major United Kingdom (UK) sporting organisations and to summarise the evidence for each of these policies. METHODS A scoping review of TGD policies from the 15 major UK sporting organisations. RESULTS Eleven of the governing bodies had publicly available TGD policies. Most of the sporting associations drew guidance from the official 2015 IOC Consensus Meeting on Sex Reassignment and Hyperandrogenism, particularly with regard to physiological testosterone levels. Many organisations referenced their policies as a guide for decision making but stated that they ultimately made case-by-case decisions on an athlete's eligibility. Relevant considerations not addressed in most policies included pre- versus post-pubertal athletes, justification for testosterone thresholds, the length of time out of competitive action (if any) for transitioning athletes, the irreversible advantage from male puberty (if any), the responsibility for and frequency of follow up for hormonal testing and the consequences for athletes outside set testosterone limits. CONCLUSIONS There is a lack of consensus among the top 15 UK sporting organizations relating to elite sport participation for TGD athletes. It would be useful for sport organizations to work together to develop greater standardization/consensus for TGD athlete policies, taking into consideration fairness, safety and inclusion in each sport.

Abstract
AIMS AND OBJECTIVES To explore the rigour of nurse-led quality improvement projects involving education, training or continuing professional development, and examine evaluation frameworks contained within. BACKGROUND Healthcare organisations invest significantly in quality improvement in the pursuit of cost-effective, safe, evidence-based and person-centred care. Consequently, efforts to examine the success of investment in quality improvement activities are prominent, against a backdrop of rising healthcare expenditure, reforms, consumer expectations and feedback. DESIGN A qualitative document analysis of quality improvement projects located in a local health district repository was undertaken. METHODS N = 3004 projects were screened against inclusion criteria, with n = 160 projects remaining for analysis. Projects were mapped to an adapted version of the Standards for QUality Improvement Reporting Excellence (SQUIRE), specifically the education extension (SQUIRE-EDU). Additionally, project evaluation frameworks were positioned within Kirkpatrick's four levels of training evaluation model. The SQUIRE checklist was also applied in line with EQUATOR guidelines. RESULTS Of n = 60 completed projects assessed against four broad SQUIRE-EDU categories and relevant criteria, n = 36 were assessed not to have met any categories, n = 14 projects met one category, n = 8 projects met two categories, and n = 2 projects met three categories. None of the completed projects met all four SQUIRE-EDU categories. There was insufficient documentation relating to evaluation frameworks in n = 133 projects to position within Kirkpatrick's four levels of training evaluation. CONCLUSIONS Scientific rigour should underpin all quality improvement efforts. We recommend that SQUIRE international consensus guidelines (full or abridged) should guide both the design and reporting of all local quality improvement efforts. RELEVANCE TO CLINICAL PRACTICE To be of value to the expansion of evidence-based practice, quality improvement platforms should be designed to reflect the structural logic, rigour and reporting recommendations being advocated in consensus reporting guidelines. This may require investment in training and development programs, and identification of governance and support systems. No Patient or Public Contribution, as the study was retrospective in nature and involved a health service repository of quality improvement projects accessible to health service staff only.

Abstract
The precise and accurate identification and quantification of transcriptional start sites (TSSs) is key to understanding the control of transcription. The core promoter consists of the TSS and proximal non-coding sequences, which are critical in transcriptional regulation. Therefore, the accurate identification of TSSs is important for understanding the molecular regulation of transcription. Existing protocols for TSS identification are challenging and expensive, leaving high-quality data available for a small subset of organisms. This sparsity of data impairs study of TSS usage across tissues or in an evolutionary context. To address these shortcomings, we developed Smart-Seq2 Rolling Circle to Concatemeric Consensus (Smar2C2), which identifies and quantifies TSSs and transcription termination sites. Smar2C2 incorporates unique molecular identifiers that allowed for the identification of as many as 70 million sites, with no known upper limit. We have also generated TSS data sets from as little as 40 pg of total RNA, which was the smallest input tested. In this study, we used Smar2C2 to identify TSSs in Glycine max (soybean), Oryza sativa (rice), Sorghum bicolor (sorghum), Triticum aestivum (wheat) and Zea mays (maize) across multiple tissues. This wide panel of plant TSSs facilitated the identification of evolutionarily conserved features, such as novel patterns in the dinucleotides that compose the initiator element (Inr), that correlated with promoter expression levels across all species examined. We also discovered sequence variations in known promoter motifs that are positioned reliably close to the TSS, such as differences in the TATA box and in the Inr that may prove significant to our understanding and control of transcription initiation. Smar2C2 allows for the easy study of these critical sequences, providing a tool to facilitate discovery.

Abstract
BACKGROUND Empirical evidence supports the use of structured goals of care conversations and documentation of life-sustaining treatment (LST) preferences in durable, accessible, and actionable orders to improve the care for people living with serious illness. As the largest integrated healthcare system in the USA, the Veterans Health Administration (VA) provides an excellent environment to test implementation strategies that promote this evidence-based practice. The Preferences Elicited and Respected for Seriously Ill Veterans through Enhanced Decision-Making (PERSIVED) program seeks to improve care outcomes for seriously ill Veterans by supporting efforts to conduct goals of care conversations, systematically document LST preferences, and ensure timely and accurate communication about preferences across VA and non-VA settings. METHODS PERSIVED encompasses two separate but related implementation projects that support the same evidence-based practice. Project 1 will enroll 12 VA Home Based Primary Care (HBPC) programs and Project 2 will enroll six VA Community Nursing Home (CNH) programs. Both projects begin with a pre-implementation phase during which data from diverse stakeholders are gathered to identify barriers and facilitators to adoption of the LST evidence-based practice. This baseline assessment is used to tailor quality improvement activities using audit with feedback and implementation facilitation during the implementation phase. Site champions serve as the lynchpin between the PERSIVED project team and site personnel. PERSIVED teams support site champions through monthly coaching sessions. At the end of implementation, baseline site process maps are updated to reflect new steps and procedures to ensure timely conversations and documentation of treatment preferences. During the sustainability phase, intense engagement with champions ends, at which point champions work independently to maintain and improve processes and outcomes. Ongoing process evaluation, guided by the RE-AIM framework, is used to monitor Reach, Adoption, Implementation, and Maintenance outcomes. Effectiveness will be assessed using several endorsed clinical metrics for seriously ill populations. DISCUSSION The PERSIVED program aims to prevent potentially burdensome LSTs by consistently eliciting and documenting values, goals, and treatment preferences of seriously ill Veterans. Working with clinical operational partners, we will apply our findings to HBPC and CNH programs throughout the national VA healthcare system during a future scale-out period.

Abstract
Abstract
Study question
What is the penetrance of variants in previously reported genes for premature ovarian insufficiency (POI) in the general population?
Summary answer
Heterozygous genetic variants in previously reported monogenic genes are not a common, highly penetrant cause of POI.
What is known already
Premature ovarian insufficiency (POI), defined as menopause before 40, has been associated with variants in over 70 genes. However, the evidence to support the causality of individual genetic variants varies between studies. As genomic data becomes more accessible, it is essential to ascertain the penetrance of variants in the absence of family history information. We identified 75 genes associated with POI from the literature, including family segregation studies, consanguineous pedigrees and cohort analyses of whole-exome/targeted sequencing data. Functional evaluation was also available for many of the genes.
Study design, size, duration
We used data from 101,127 females of European ancestry in the UK Biobank, to study the role of previously reported monogenic causal genes on ovarian function. We tested the association of 301 previously reported variants with POI and ANM, plus more than 2.5 million rare variants which were annotated and had not been implicated in POI previously. Genomic variants were tested individually and also combined into a gene burden test.
Participants/materials, setting, methods
Age at natural menopause (ANM) was derived from self-reported questionnaire data from the age at last menstrual period, excluding those with surgical menopause or taking hormone replacement therapy. POI cases were classified as women with ANM under 40 years (N = 2,213). Linked primary care records were used to identify a clinical cohort of POI cases, including primary amenorrhea (N = 113).
Main results and the role of chance
All of the previously reported individual variants we identified in our POI cases were also detected in the control group. Moreover, the gene burden tests were not associated with POI or ANM as a quantitative trait. Our results indicate that autosomal dominant causes of POI are rare; a single predicted loss-of-function (LOF) or non-synonymous genetic variant in one of the previously reported genes is generally not pathogenic.
Limitations, reasons for caution
The penetrance of monogenic disease-causing variants is likely to be lower in population-based cohorts such as UK Biobank than in clinically-ascertained cohorts.
Wider implications of the findings
Heterozygous LOF or non-synonymous variants in previously reported POI genes should be interpreted with caution and are unlikely to cause POI. The findings have implications for clinicians diagnosing causes of POI.

Abstract
The metabolic syndrome (MetS) is a cluster of cardiovascular risk factors characterised by central obesity, atherogenic dyslipidaemia, and changes in the circulating lipidome; the underlying mechanisms that lead to this lipid remodelling have only been partially elucidated. This study used an integrated "omics" approach (untargeted whole serum lipidomics, targeted proteomics, and lipoprotein lipidomics) to study lipoprotein remodelling and HDL composition in subjects with central obesity diagnosed with MetS (vs. controls). Compared with healthy subjects, MetS patients showed higher free fatty acids, diglycerides, phosphatidylcholines, and triglycerides, particularly those enriched in products of de novo lipogenesis. On the other hand, the "lysophosphatidylcholines to phosphatidylcholines" and "cholesteryl ester to free cholesterol" ratios were reduced, pointing to a lower activity of lecithin cholesterol acyltransferase (LCAT) in MetS; LCAT activity (directly measured and predicted by lipidomic ratios) was positively correlated with high-density lipoprotein cholesterol (HDL-C) and negatively correlated with body mass index (BMI) and insulin resistance. Moreover, many phosphatidylcholines and sphingomyelins were significantly lower in the HDL of MetS patients and strongly correlated with BMI and clinical metabolic parameters. These results suggest that MetS is associated with an impairment of phospholipid metabolism in HDL, partially led by LCAT, and associated with obesity and underlying insulin resistance. This study proposes a candidate strategy to use integrated "omics" approaches to gain mechanistic insights into lipoprotein remodelling, thus deepening the knowledge regarding the molecular basis of the association between MetS and atherosclerosis.

Abstract
Abstract
Introduction
Poor health-related quality of life (HRQoL) is associated with higher morbidity and mortality in patient populations. However, whether HRQoL is associated with health outcomes among community-dwelling older people requires further investigation. This study aimed to examine whether HRQoL predicts cognitive decline, dementia, cardiovascular disease (CVD), and mortality in community-dwelling older people living in Australia and the United States.
Method
A cohort of 19,106 individuals from the ASPirin in Reducing Events in the Elderly (ASPREE) study, aged 65–98 years, initially free of dementia or CVD, and who completed the HRQoL 12-item short form (SF-12, version-2) at baseline (2010–2014), were followed until June 2017. The physical (PCS) and mental component scores (MCS) of SF-12 were generated using standardized norm-based method.
Results
Over a median of 4.7 years, there were 2,412 cognitive declines, 574 dementia, 922 incident CVD events, and 1,052 deaths. Using Cox proportional-hazard regression adjusted for a range of covariates, every 10-unit increase in PCS was associated with a 6% lower risk of cognitive decline, a 14% lower risk of incident CVD, and 17% lower risk of all-cause mortality, but was not associated with incident dementia. In contrast, higher MCS was only associated with a 12% and 15% lower risk of cognitive decline and dementia, respectively. Findings did not differ by sex.
Conclusion
Our study provides some of the first evidence that HRQoL can be used in combination with clinical data to identify the future risks of health outcomes among older individuals living in the community. Our findings support the decision of the Australian Commission on Safety and Quality in Health Care to incorporate the SF-12 into the annual Patient-Reported Outcome Measures (PROMs assessment.

Abstract
BackgroundJuvenile localised scleroderma (JLS) or morphea is a rare condition, causing inflammation and fibrosis in skin and underlying tissues. A validated skin score (Localized Scleroderma Cutaneous Assessment Tool, LoSCAT) has been developed [1]. This tool has both activity (mLoSSi) and damage indices (LoSDI). Several patient-reported outcomes (PRO) have been studied in JLS including visual analogue scales (VAS), functional and health-related quality of life measures.ObjectivesTo assess the associations between different PROs and the activity and damage indices of the LoSCAT.MethodsParticipants aged 4 to 17 were recruited from 3 tertiary paediatric rheumatology centres in the UK and attended 4 visits at 3 monthly intervals as part of a program of research on JLS. Patient-reported VAS (6 different scales), the Children’s Dermatology Life Quality Index (CDLQI) and Childhood Health Assessment Questionnaires (CHAQ) were completed at each visit. LoSCAT was completed by the two same clinicians throughout the study (both trained in skin score techniques). Pearson correlation coefficients were calculated between each PRO and each component of the LoSCAT.Results24 participants completed all 4 visits and 1 attended 3 visits. 20 participants were female (80%) and 5 were male (20%). Mean age at diagnosis was 7.6 years with mean disease duration of 4.9 years. Subtype of disease was linear head in 5/25 (20%), linear limb 12/25 (48%), generalised morphoea 1/25 (4%), mixed 5/25 (20%) and superficial plaque in 2/25 (8%). Table 1 shows the correlations with figures in bold highlighting positive correlations which were statistically significant (p<0.05) and medium-sized (r>0.3).Table 1.Correlation between patient reported outcomes and LoSCATPROTotal skin activity (mLoSSi)Total skin damage (LoSDI)r (95% CI)p-valuer (95% CI)p-valueCDLQI0.61 (0.02, 1.20)0.0440.42 (0.01, 0.83)0.044CHAQ0.30 (0.03, 0.57)0.0270.20 (-0.14, 0.54)0.244VAS 1: How much IMPACT has your disease had on your life in the PAST MONTH?0.49 (0.00, 0.98)0.0500.38 (0.06, 0.71)0.021VAS 2: How much has your condition (localized scleroderma) affected you OVERALL in the PAST MONTH?0.59 (0.09, 1.09)0.0220.42 (0.13, 0.72)0.005VAS 3: Have your lesions felt itchy and/or scratchy in PAST MONTH?0.40 (-0.01, 0.81)0.0560.31 (0.03, 0.59)0.028VAS 4: Have you felt numbness, tingling, and/or other “funny” feeling in or around your lesion in PAST MONTH?0.55 (0.04, 1.05)0.0330.33 (-0.04, 0.71)0.084VAS 5: How much WORRY do you have about LONG- -TERM problems from your disease?0.40 (-0.01, 0.81)0.0530.32 (0.00, 0.63)0.047VAS 6: How much WORRY do you have about problems from MEDICATIONS used to treat your condition?0.41 (0.00, 0.82)0.0500.29 (-0.09, 0.66)0.131The VAS of symptoms of numbness/tingling showed a strong positive correlation with mLoSSi but a weak and/or non-significant correlation with LoSDI. VAS itchy/scratchy did not show a strong correlation with mLoSSi but showed a moderate correlation with LoSDI. Patient global VAS correlated with both mLoSSi and LoSDI, as did CDLQI. CHAQ correlated with activity only.ConclusionSymptoms within lesions are often interpreted as indicating disease activity. A previous study in adults and children showed itch positively correlated with mLoSSi suggesting it may be a marker of active disease [2]. However, in our study numbness/tingling correlated with disease activity whereas itch did not. Further work is required to understand whether itch correlates to both activity and damage and whether numbness/tingling is a better indicator of activity than itch. Limitations of our study include a heterogenous group of participants with longstanding high-burden disease.References[1]Arkachaisri et al. Rheumatology 2010. 49(2): 373-81.[2]Klimas et al.

Abstract
Introduction Vascular risk factors including hypertension, diabetes and dyslipidaemia promote diverse pathological mechanisms in the brain leading to cerebral hypoperfusion and ultimately cognitive decline in people. Medial temporal, medial frontal and anterior cingulate atrophy has been closely associated with diabetes and medial temporal lobe atrophy is associated with hypertension in people with Alzheimer’s disease (AD). Objectives To assess if hypertension, diabetes and dyslipidaemia have differential effects on different brain locations using brain imaging in people with AD. Methods The current study is based on [18F] fluorodeoxyglucose- positron emission tomography (FDG-PET) data of 970 participants from two large Phase III multi-centre clinical trials of a novel tau aggregation inhibitor drug Leuco-Methylthioninium (LMTX)meeting research criteria for mild to moderate AD. Vascular risk factor data including hypertension, diabetes and dyslipidaemia were collected and quantification of FDG PET hypo-metabolism was done by calculating Standardized Uptake Value Ratio(SUVR). Results Hypertension, diabetes and dyslipidaemia were found to have differential effects on brain locations in people with AD. When people with hypertension, diabetes and dyslipidaemia were compared to those without, mean SUVR was increased significantly in both left and right parietal and occipital lobes and decreased in left and right anterior cingulate gyri in hypertensives. SUVR was significantly higher in both left and right temporal lobes in diabetics andlower in both left and right anterior cingulate gyri in people with dyslipidaemia. Conclusions Vascular risk factors including hypertension, diabetes and dyslipidaemia have differential effects on different brain regions, measured using SUVR analysis of FDG-PET. Disclosure The FDG-PET data was taken from participants of two large phase III clinical trials sponsored by TauRx Therapeutics (Singapore).

Abstract
BackgroundOutcome measures which can differentiate activity (inflammation) from damage (fibrosis/atrophy) would facilitate development of new treatment strategies in juvenile localized scleroderma (JLS) to target the inflammatory phase of the disease.ObjectivesTo evaluate whether in JLS, non-invasive imaging modalities (high frequency ultrasounds (HFUS), multispectral imaging (MSI), laser doppler imaging (LDI) & infra-red thermography (IRT)) can detect differences between affected & non-affected skin, as a next step in developing these as outcome measures. Our hypothesis was that blood flow (and therefore temperature & oxygenation) would be increased in lesional skin.MethodsParticipants aged 4-17 were recruited from 3 paediatric rheumatology centres in the UK. For each participant, a single lesion was selected. HFUS (30MHz), MSI (bespoke camera and tuneable liquid crystal filter, coupled to custom analysis software, 500nm/710nm wavelengths), LDI and IRT imaging were performed at four sites relating to each lesion: two of affected skin (centre & inner edge of lesion) and two of non-affected skin (one cm from edge of lesion (‘outer’) & contralateral unaffected side). Imaging was performed at 4 visits at 3 monthly intervals. Mean values were compared between the four sites using data from all visits by mixed-effects linear regression to account for individual-level clustering.Results24 participants completed all 4 visits and 1 attended 3. 20 participants were female (80%) & 5 male (20%). Mean age at diagnosis was 7.6 years & disease duration 4.9 years. Subtype of disease was linear head in 5/25 (20%), linear limb 12/25 (48%), generalised morphea 1/25 (4%), mixed 5/25 (20%) and superficial plaque in 2/25 (8%).Table 1 shows a subset of data. All 4 imaging techniques could detect differences between healthy (outer/contralateral) & affected skin (centre/inner edge). For HFUS, there was strong evidence of a difference between affected & unaffected skin (p<0.001) indicating affected skin is thinner than unaffected. Higher mean values of oxygenation, perfusion & temperature were observed in affected compared to non-affected skin in MSI, LDI and IRT respectively. There was no statistical difference seen between inner edge and centre of the lesion in any of the methods.Table 1.Mean differences between different locations for each imaging techniqueImaging techniqueLocationOverall mean difference (95% CI)p-valueHFUS (mm)Centre - Contralateral-0.34 (-0.46, -0.22)<0.001Inner edge - Contralateral-0.30 (-0.40, -0.20)<0.001Centre - Outer-0.35 (-0.46, -0.24)<0.001Inner edge - Outer-0.31 (-0.40, -0.21)<0.001Centre - Inner edge-0.04 (-0.10, 0.02)0.168MSI (rel units)Centre - Contralateral0.06 (0.03, 0.10)<0.001Inner edge - Contralateral0.06 (0.03, 0.09)<0.001Centre - Outer0.04 (0.01, 0.07)0.012Inner edge - Outer0.03 (0.00, 0.06)0.028Centre - Inner edge0.01 (0.00, 0.02)0.251LDI Relative perfusion unitsCentre - Contralateral44.8 (24.4, 65.2)<0.001Inner edge - Contralateral47.9 (21.0, 74.8)<0.001Centre - Outer19.1 (1.0, 37.1)0.039Inner edge - Outer24.8 (6.7, 42.9)0.007Centre - Inner edge-3.5 (-20.3, 13.2)0.679IRT oCCentre - Contralateral0.58 (0.24, 0.91)0.001Inner edge - Contralateral0.44 (0.13, 0.75)0.005Centre - Outer0.44 (0.22, 0.66)<0.001Inner edge - Outer0.30 (0.09, 0.52)0.006Centre - Inner edge0.14 (-0.05, 0.32)0.153The overall mean difference is the measurement of the first location minus the measurement from the second location (e.g. centre minus contralateral), averaged across the four visits.ConclusionOur results suggest non-invasive imaging can detect differences between healthy & unaffected skin in JLS.

Abstract
Objectives The purpose of this prospective study was to report incidence and transmission of SARS-CoV-2, among professional golfers and essential support staff undergoing risk assessment and enhanced risk reduction measures when considered a close contact as opposed to standard isolation while competing on the DP World Tour during the 2021 season. Methods This prospective cohort study included all players and essential support staff participating in 26 DP World Tour events from 18 April 2021 to 21 November 2021. High-risk contacts were isolated for 10 days. Moderate-risk contacts received education regarding enhanced medical surveillance, had daily rapid antigen testing for 5 days, with reverse transcriptase-polymerase chain reaction (RT-PCR) tesing on day 5, mandated mask use and access to outside space for work purposes only. Low-risk contacts typically received rapid antigen testing every 48 hours and RT-PCR testing on day 5. Results The total study cohort compromised 13 394 person-weeks of exposure. There were a total of 30 positive cases over the study period. Eleven contacts were stratified as ‘high risk’. Two of these subsequently tested positive for SARS-CoV-2. There were 79 moderate-risk contact and 73 low-risk contacts. One moderate-risk contact subsequently tested positive for SARS-CoV-2 but did not transmit the virus. All other contacts, remained negative and asymptomatic to the end of the tournament week. Conclusions A risk assessment and risk reduction-based approach to contact tracing was safe in this professional golf event setting when Alpha and Delta were the predominant variants. It enabled professional golfers and essential support staff to work.

Abstract
Objectives This pilot study aimed to see whether a risk assessment and risk reduction approach was a practical and feasible approach, as compared with standard isolation for fully vaccinated, asymptomatic persons positive for SARS-CoV-2. Methods This prospective cohort study included all players and caddies participating in two large professional golf events from 7 to 20 February 2022 in South Africa. Fully vaccinated persons testing positive who were asymptomatic were subject to risk assessment and risk reduction measures to protect the integrity of the event. Asymptomatic individuals who could socially distance in outdoor areas were allowed to participate. Close contacts were subject to daily rapid antigen tests and asked to prioritise outdoor space. Results The protocols put in place for the events were practical, feasible, and well accepted by event participants and staff during the study period. There was a total of 378 player-week episodes and 378 caddie-week episodes during the study period. Three persons tested positive while registered at events during the study period (0.4% of person episodes). The positive tests were returned from two players and one caddie, all of which were asymptomatic at the time of testing. There was one high-risk contact who consistently returned negative antigen tests. There was no evidence of transmission. Conclusions The approach was practical and feasible. A risk assessment and risk reduction approach allowed fully vaccinated asymptomatic persons with SARS-CoV-2 to participate in golf, an outdoor sport where social distancing is possible, compared with standard isolation.

Abstract
INTRODUCTION Phenibut is a psychoactive drug with GABAB agonism. It remains unregulated and easily attainable in the United States, where it has become a novel drug of abuse. CASE PRESENTATION We present the case of a 34-year-old man who used phenibut consistently for 3 years. After 6 months of use, he developed signs of dependence and failed outpatient detoxification. While taking high doses, he experienced parasomnia-like symptoms and periods of dysexecutive function. After abrupt cessation, he developed severe withdrawal symptoms, was hospitalized, and required intubation. His condition improved after 1 week of treatment. After recovery and discharge, he remains stable utilizing an extended taper of acamprosate and baclofen. DISCUSSION Phenibut is not detected on urine drug screen and withdrawal symptoms are nonspecific. Optimal treatment of withdrawal remains unknown. Baclofen and phenobarbital have been successful for treatment of dependence. CONCLUSION Clinicians should be aware of phenibut abuse and the potential for dependence and withdrawal.

Abstract
BACKGROUND For patients with early American Joint Committee on Cancer (AJCC)-stage melanoma the combined loss of the autophagy regulatory protein AMBRA1 and the terminal differentiation marker loricrin in the peritumoral epidermis is associated with a significantly increased risk of metastasis. OBJECTIVES The aim of the present study was to evaluate the potential contribution of melanoma paracrine transforming growth factor (TGF)-β signalling to the loss of AMBRA1 in the epidermis overlying the primary tumour and disruption of epidermal integrity. METHODS Immunohistochemistry was used to analyse AMBRA1 and TGF-β2 in a cohort of 109 AJCC all-stage melanomas, and TGF-β2 and claudin-1 in a cohort of 30 or 42 AJCC stage I melanomas, respectively, with known AMBRA1 and loricrin (AMLo) expression. Evidence of pre-ulceration was analysed in a cohort of 42 melanomas, with TGF-β2 signalling evaluated in primary keratinocytes. RESULTS Increased tumoral TGF-β2 was significantly associated with loss of peritumoral AMBRA1 (P < 0·05), ulceration (P < 0·001), AMLo high-risk status (P < 0·05) and metastasis (P < 0·01). TGF-β2 treatment of keratinocytes resulted in downregulation of AMBRA1, loricrin and claudin-1, while knockdown of AMBRA1 was associated with decreased expression of claudin-1 and increased proliferation of keratinocytes (P < 0·05). Importantly, we show loss of AMBRA1 in the peritumoral epidermis was associated with decreased claudin-1 expression (P < 0·05), parakeratosis (P < 0·01) and cleft formation in the dermoepidermal junction (P < 0·05). CONCLUSIONS Collectively, these data suggest a paracrine mechanism whereby TGF-β2 causes loss of AMBRA1 overlying high-risk AJCC early-stage melanomas and reduced epidermal integrity, thereby facilitating erosion of the epidermis and tumour ulceration.

Abstract
Summarising and synthesising the evidence on cricket health and wellbeing can help inform cricket stakeholders and navigate future research directions. The purpose of this study was to investigate the relationship between cricket participation, health and wellbeing at all ages and playing standards, and identify research gaps in the existing literature. A scoping review was performed from inception to March, 2020. Studies were included if they assessed a construct related to health and/or wellbeing in cricketers, available in English. 219 articles were eligible. Injury incidence per 1,000 player exposures ranged from 1.8-5.7 injuries. 48% of former cricketers experienced persistent joint pain. However, former cricketers reported greater physical activity levels and mental-components of quality of life compared to the general population. Heat injury/illness and skin cancer are concerns and require further research. Cricket participation is associated with an inherent injury risk, which may have negative implications for musculoskeletal health in later life. However, cricket participation is associated with high quality of life which can persist after retirement. Gaps in the literature include prospective studies on health and wellbeing of cricketers, female cricketers, injury prevention strategies, and the impact of cricket participation on metabolic health and lifetime physical activity.

Abstract
Objective To determine the frequency of germline and somatic pathogenic BRCA1 and BRCA2 variants in patients with high‐grade serous ovarian cancer tested by next‐generation sequencing (NGS), with the aim of defining the best strategy to be implemented in future routine testing. Design National retrospective audit. Setting The All Wales Medical Genomics Service (AWMGS). Population Patients with high‐grade serous ovarian/fallopian tube/peritoneal cancer referred by oncologists to the AWMGS between February 2015 and February 2021 for germline and/or tumour testing of the BRCA1 and BRCA2 genes by NGS. Methods Analysis of NGS data from germline and/or tumour testing. Main outcome measures Frequency of BRCA1 and BRCA2 pathogenic variants. Results The overall observed germline/somatic pathogenic variant detection rate was 11.6% in the 844 patients included in this study, with a 9.2% (73/791) germline pathogenic variant detection rate. Parallel tumour and germline testing was carried out for 169 patients and the overall pathogenic variant detection rate for this cohort was 14.8%, with 6.5% (11/169) shown to have a somatic pathogenic variant. Two BRCA1 dosage variants were found during germline screens, representing 2.0% (2/98) of patients with a pathogenic variant that would have been missed through tumour testing alone. Conclusions Parallel germline and tumour BRCA1 and BRCA2 testing maximises the detection of pathogenic variants in patients with high‐grade serous ovarian cancer. Tweetable abstract Parallel germline and tumour testing maximises BRCA pathogenic variant detection in ovarian cancer. Parallel germline and tumour testing maximises BRCA pathogenic variant detection in ovarian cancer. Linked article This article is commented on by C Gourley, p. 443 in this issue.

Abstract
UNLABELLED In 1990, the last time the decennial census included a question on domestic drinking water source, it was estimated that private domestic water wells (PDWs) supplied household water to about 15.1 million housing units (15% of the population) in the United States (U.S.). PDWs are not regulated by the Safe Drinking Water Act, and with few exceptions, are not subject to the water quality testing required of public water suppliers. We expanded two methods in estimating housing units reliant on PDWs from an Oklahoma pilot study (Weaver et al. 2017), nationally. Both use 1990 census data on drinking water sources as a baseline. The first method uses housing unit change and private well drilling logs for 20 states. This allows for the rate of well use to change between 1990 and 2010 in these states. The second, based solely on housing unit change, assumes a constant rate of well use. Ordinary least squares regression demonstrated (R 2 = 0.78) that the methods yield similar estimates for nationwide well use. Using the housing unit change method, it is estimated that in 2010, 23 million housing units were reliant on PDWs (17% of the population). We provide these estimates at the census block group and census block resolution. This dataset will assist in a better understanding of the reliance on PDWs in the U.S., and position local, tribal, state, and national groups to better protect this water resource from contaminant sources. RESEARCH IMPACT STATEMENT The work provides improved estimates of the spatial distribution of housing units reliant on private domestic wells in the United States and a foundation to protect this water supply at all levels of government.

Abstract
Objectives The aim of this study was to assess whether a risk assessment and managed risk approach to contact tracing was practical and feasible at the Gran Canaria Lopesan Open 2021 and could inform further pilot work regarding disease transmission during elite sporting events. Methods This prospective cohort study included all international attendees. All participants required a minimum of one negative reverse transcriptase PCR (RT-PCR) test prior to travelling to each tournament. High-risk contacts were isolated for 10 days. Moderate-risk contacts received education regarding enhanced medical surveillance, had daily rapid antigen testing for 5 days, with RT-PCR day 5, mandated mask use and access to outside space for work purposes only. Low-risk contacts received rapid antigen testing every 48 hours and PCR testing on day 5. Results A total of 550 persons were accredited and were required to undergo RT-PCR testing before the event. Two of these tests were positive (0.36%). Of these, case 1 had 1 high, 23 moderate and 48 low-risk contacts. Case 2 did not have any significant travel history within 2 days of positive test and had one high-risk contact. There were no further positive tests on site in the wider cohort of attendees, from a total of 872 RT-PCR and 198 rapid antigen tests. Conclusions This pilot study showed it is practical, feasible and well accepted to provide enhanced (daily) virus testing and risk-mitigating measures at a professional golf event. Further study is required to assess the efficacy of these interventions; however, no transmission was found in this pilot study.

Abstract
INTRODUCTION Older adults with serious illness frequently receive post-acute rehabilitative care in nursing homes (NH) under the Part A Medicare Skilled Nursing Facility (SNF) Benefit. Treatment is commonly focused on disease-modifying therapies with minimal consideration for goals of care, symptom relief, and other elements of palliative care. INTERVENTION The evidence-based Primary Palliative Care in Post-Acute Care (PPC-PAC) intervention for older adults is delivered by nurse practitioners (NP). PPC-PAC NPs assess and manage symptoms, conduct goals of care discussions and assist with decision making; they communicate findings with NH staff and providers. Implementation of PPC-PAC includes online and face-to-face training of NPs, ongoing facilitation, and a template embedded in the NH electronic health record to document PPC-PAC. OBJECTIVES The objectives of this pilot pragmatic clinical trial are to assess the feasibility, acceptability, and preliminary effectiveness of the PPC-PAC intervention and its implementation for 80 seriously ill older adults newly admitted to a NH for post-acute care. METHODS Design is a two-arm nonequivalent group multi-site pilot pragmatic clinical trial. The unit of assignment is at the NP and unit of analysis is NH patients. Recruitment occurs at NHs in Pennsylvania, New Jersey, Delaware, and Maryland. Effectiveness (patient quality of life) data are collected at two times points-baseline and 14-21 days. CONCLUSION This will be the first study to evaluate the implementation of an evidence-based primary palliative care intervention specifically designed for older adults with serious illness who are receiving post-acute NH care.

Abstract
BACKGROUND There is strong evidence that epigenetic age acceleration is associated with increased risk of later-life diseases and all-cause mortality. However, there is currently limited evidence that suggests accelerated epigenetic age is associated with dementia risk. OBJECTIVE This study aims to clarify whether epigenetic biomarkers of accelerated aging can predict dementia risk, which is an important consideration as aging is the greatest risk factor for the disease. METHODS DNA methylation was measured in peripheral blood samples provided by 160 participants from the ASPirin in Reducing Events in the Elderly study, including 73 pre-symptomatic dementia cases and 87 controls matched for age, sex, and smoking and education status. Epigenetic age was calculated using Horvath, Hannum, GrimAge and PhenoAge DNA methylation clocks, and age acceleration (the disparity between chronological age and epigenetic age) was determined. RESULTS There was no difference in age acceleration between dementia cases and controls. In males, only Hannum's intrinsic epigenetic age acceleration was increased in pre-symptomatic dementia cases compared to controls (Δ +1.8 years, p = 0.03). CONCLUSION These findings provide no strong evidence that accelerated epigenetic aging measured in peripheral blood can predict dementia risk.

Abstract
International outdoor athletics championships are typically hosted during the summer season, frequently in hot and humid climatic conditions. Therefore, we analyzed the association between apparent temperature and heat-related illnesses occurrence during international outdoor athletics championships and compared its incidence rates between athletics disciplines. Heat-related illnesses were selected from illness data prospectively collected at seven international outdoor athletics championships between 2009 and 2018 using a standardized methodology. The Universal Thermal Climate Index (UTCI) was calculated as a measure of the apparent temperature based on weather data for each day of the championships. Heat-related illness numbers and (daily) incidence rates were calculated and analyzed in relation to the daily maximum UTCI temperature and between disciplines. During 50 championships days with UTCI temperatures between 15℃ and 37℃, 132 heat-related illnesses were recorded. Average incidence rate of heat-related illnesses was 11.7 (95%CI 9.7 to 13.7) per 1000 registered athletes. The expected daily incidence rate of heat-related illnesses increased significantly with UTCI temperature (0.12 more illnesses per 1000 registered athletes/°C; 95%CI 0.08-0.16) and was found to double from 25 to 35°C UTCI. Race walkers (RR = 45.5, 95%CI 21.6-96.0) and marathon runners (RR = 47.7, 95%CI 23.0-98.8) had higher heat-related illness rates than athletes competing in short-duration disciplines. Higher UTCI temperatures were associated with more heat-related illnesses, with marathon and race walking athletes having higher risk than athletes competing in short-duration disciplines. Heat-related illness prevention strategies should predominantly focus on marathon and race walking events of outdoor athletics championships when high temperatures are forecast.
