Effect of Achilles Tendon Rupture on Player Performance and Longevity in Women\u27s National Basketball Association Players

Background: Women\u27s National Basketball Association (WNBA) players have a greater incidence of lower extremity injury compared with male players, yet no data exist on functional outcomes after Achilles tendon rupture (ATR). Purpose: To evaluate the effect of Achilles tendon repair on game utilization, player performance, and career longevity in WNBA athletes. Study Design: Cohort study; Level of evidence, 3. Methods: WNBA players from 1997 to 2019 with a history of ATR (n = 12) were matched 1:2 to a healthy control group. Player characteristics, game utilization, and in-game performance data were collected for each athlete, from which the player efficiency rating (PER) was calculated. Statistical analysis was performed comparing postinjury data to preinjury baseline as well as cumulative career data. Changes at each time point relative to the preinjury baseline were also compared between groups. Results: Of the 12 players with ATR, 10 (83.3%) returned to play at the WNBA level at a mean (+/- SD) of 12.5 +/- 3.3 months. Four players participated in only 1 WNBA season after injury. There were no differences in characteristics between the 10 players who returned to play after injury and the control group. After return to play, the WNBA players demonstrated a significant decrease in game utilization compared with preinjury, playing in 6.0 +/- 6.9 fewer games, starting in 12.7 +/- 15.4 fewer games, and playing 10.2 +/- 9.1 fewer minutes per game (P \u3c .05 for all). After the index date of injury, the players with Achilles repair played 2.1 +/- 1.2 more years in the WNBA, while control players played 5.35 +/- 3.2 years (P \u3c .01) Additionally, the players with Achilles repair had a significant decrease in PER in the year after injury compared with preinjury (7.1 +/- 5.3 vs 11.0 +/- 4.4; P = .02). The reduction in game utilization and decrease in PER in these players was maintained when compared with the matched controls (P \u3c .05 for both). Conclusion: The majority of WNBA players who sustained ATR were able to return to sport after their injury; however, their career longevity was shorter than that of healthy controls. There was a significant decrease in game utilization and performance in the year after return to play compared with healthy controls

Power Play: Grotesque Ornament And The Art Of Political Persuasion In Early Modern France

This study aimed to survey the use of grotesque ornament in France from the sixteenth to the eighteenth centuries, and assessed its meanings in both public and private spaces. After collecting a large number of examples of grotesque images and objects, three central themes were developed to guide further research. These themes were Appropriation, wherein the motif's historical resonance was important to the development of royal and noble legitimacy, and a symbol of power; Physical Exuberance, which took into account both the materiality of the design of grotesques and their reflection of political ideals, and lastly Visual Play, which considered how artists were using grotesques, as well as their flexibility in meaning. Each successive chapter explored how these themes operated in relation to specific examples. The Literature Review was developed in order to explore four aspects of the scholarly material currently available for the study of grotesques. First, it aimed to situate grotesques within the larger framework of new works in the field of ornament. It then began to consider how ancient works were received in sixteenth century France, and what they could offer readers about the uses and meanings of grotesque ornament. This involved a re-reading of Vitruvius, Horace, Qunitilian and Lucretius, in order to understand the ancient concepton of ornament (specifically grotesque ornament) for both its civic and rhetorical properties, and its reception in France. The review concluded with a synopsis of recent scholarship on grotesque imagery, largely from the field of decorative arts. The meanings of grotesque ornament were then explored in a chapter that aimed to give a general overview of grotesque ornament in France during the early modern period, and that expanded on the themes developed for this study. Further evidence was culled from contractual language in original documents from the period, and from a considertation of how the materiality of grotesque images might alter meaning. These ideas were then investigated through three central case studies. The first case study, centered on the printmaker, Juste de Juste, who worked at the First School of Fontainebleau in the 1540s, provided the first major study of his work. The chapter considered an artist's role within the context of Fontainebleau, the network of artists that disseminated ideas through it, and how artistic processes converged with new scientific endeavors, specifically anatomy. The case study posited that primtmaking was an essentially experimental practice for many of these artists, and that for Juste de Juste, a way to express his own identity. The second case study provided the first in-depth survey of grotesque ornament on the facades of houses in Toulouse, France. The city allowed for the examination of the civic character of the motif, as well as its relationship to forms developed at Fontainebleau. Grotesques were adapted to localized building traditions, and were made to display wealth and power in the cityscape. The next chapter on a series of grotesques painted by Simon Vouet for Anne of Austria in the 1640s similarly took up the exploration of power through ornamental display, but rather in the context of an interior space within the Palais Royal. The study found a variation in the historical appropriation of the motif, and exposed the role of female agency. It also expanded the discussion of siting royal authority in specific places, and how the dissemination of prints was important to establishing the imagery associated with that authority. These case studies were followed by an epilogue that discussed the continued use of grotesque ornament well into the eighteenth century, especially through the work of artists such as Watteau, and how the motif's flexibility allowed for its use in both Rococo and Neoclassical contexts. The epilogue alludes to the expansion of the marketplace, where the mass consumption of ornament was evident, and how this stimulated the global development of an exportable French style

LiFT: A Scalable Framework for Measuring Fairness in ML Applications

Many internet applications are powered by machine learned models, which are usually trained on labeled datasets obtained through either implicit / explicit user feedback signals or human judgments. Since societal biases may be present in the generation of such datasets, it is possible for the trained models to be biased, thereby resulting in potential discrimination and harms for disadvantaged groups. Motivated by the need for understanding and addressing algorithmic bias in web-scale ML systems and the limitations of existing fairness toolkits, we present the LinkedIn Fairness Toolkit (LiFT), a framework for scalable computation of fairness metrics as part of large ML systems. We highlight the key requirements in deployed settings, and present the design of our fairness measurement system. We discuss the challenges encountered in incorporating fairness tools in practice and the lessons learned during deployment at LinkedIn. Finally, we provide open problems based on practical experience.Comment: Accepted for publication in CIKM 202

CT colonography with minimal bowel preparation: evaluation of tagging quality, patient acceptance and diagnostic accuracy in two iodine-based preparation schemes

PURPOSE: The aim of this study was to compare a 1-day with a 2-day iodine bowel preparation for CT colonography in a positive faecal occult blood test (FOBT) screening population. MATERIALS AND METHODS: One hundred consecutive patients underwent CT colonography and colonoscopy with segmental unblinding. The first 50 patients (group 1) ingested 7 50 ml iodinated contrast starting 2 days before CT colonography. The latter 50 patients (group 2) ingested 4 50 ml iodinated contrast starting 1 day before CT colonography. Per colonic segment measurements of residual stool attenuation and homogeneity were performed, and a subjective evaluation of tagging quality (grade 1-5) was done. Independently, two reviewers performed polyp and carcinoma detection. RESULTS: The tagging density was 638 and 618 HU (p = 0.458) and homogeneity 91 and 86 HU for groups 1 and 2, respectively (p = 0.145). The tagging quality was graded 5 (excellent) in 90% of all segments in group 1 and 91% in group 2 (p = 0.749). Mean per-polyp sensitivity for lesions >or=10 mm was 86% in group 1 and 97% in group 2 (p = 0.355). Patient burden from diarrhoea significantly decreased for patients in group 2. CONCLUSIONS: One-day preparation with meglumine ioxithalamate results in an improved patient acceptability compared with 2-day preparation and has a comparable, excellent image quality and good diagnostic performanc

Topical NSAIDs for chronic musculoskeletal pain: systematic review and meta-analysis

A previous systematic review reported that topical NSAIDs were effective in relieving pain in chronic conditions like osteoarthritis and tendinitis. More trials, a better understanding of trial quality and bias, and a reclassification of certain drugs necessitate a new review. Studies were identified by searching electronic databases, and writing to manufacturers. We identified randomised, double blind trials comparing topical NSAID with either placebo or another active treatment, in adults with chronic pain. The primary outcome was a reduction in pain of approximately 50% at two weeks, and secondary outcomes were local and systemic adverse events and adverse event-related withdrawals. Relative benefit and number-needed-to-treat (NNT), and relative harm and number-needed-to-harm (NNH) were calculated, and the effects of trial quality, validity and size, outcome reported, and condition treated, were examined by sensitivity analyses. Twelve new trials were added to 13 trials from a previous review. Fourteen double blind placebo-controlled trials had information from almost 1,500 patients. Topical NSAID was significantly better than placebo with relative benefit 1.9 (95% confidence interval 1.7 to 2.2), NNT 4.6 (95% confidence interval 3.8 to 5.9). Results were not affected by trial quality, validity or size, outcome reported, or condition treated. Three trials with 764 patients comparing a topical with an oral NSAID found no difference in efficacy. Local adverse events (6%), systemic adverse events (3%), or the numbers withdrawing due to an adverse event were the same for topical NSAID and placebo. Topical NSAIDs were effective and safe in treating chronic musculoskeletal conditions for two weeks. Larger and longer trials are necessary to fully elucidate the place of topical NSAIDs in clinical practice

Systematic review of dexketoprofen in acute and chronic pain

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Background: Dexketoprofen, an NSAID used in the management of acute and chronic pains, is licensed in several countries but has not previously been the subjected of a systematic review. We used published and unpublished information from randomised clinical trials (RCTs) of dexketoprofen in painful conditions to assess evidence on efficacy and harm. Methods: PubMed and Cochrane Central were searched for RCTs of dexketoprofen for pain of any aetiology. Reference lists of retrieved articles and reviews were also searched. Menarini Group produced copies of published and unpublished studies (clinical trial reports). Data were abstracted into a standard form. For studies reporting results of single dose administration, the number of patients with at least 50 % pain relief was derived and used to calculate the relative benefit (RB) and number-needed-to-treat (NNT) for one patient to achieve at least 50 % pain relief compared with placebo. Results: Thirty-five trials were found in acute pain and chronic pain; 6,380 patients were included, 3,381 receiving dexketoprofen. Information from 16 trials (almost half the total patients) wa
