The optimal recanalization goal and number of endovascular thrombectomy (EVT) passes for elderly patients with large vessel occlusion strokes is unclear. Consecutive patients 80 years or older undergoing EVT were identified from 2016 to 2022 at a single center. Clinical information, procedural details, and modified treatment in cerebral ischemia (mTICI) scores were collected. Primary outcome was modified Rankin scale (mRS) at 90 days. Bivariate and multivariable analyses were conducted to assess associations between mTICI scores, EVT passes, and 90-day outcomes. One hundred twenty-six patients were identified. At 90 days, mTICI 2b recanalization resulted in high rates of poor outcomes (8.7% functional independence and 60.9% mortality) not significantly different from mTICI 0, 1 or 2a (median mRS 6 vs. 6, P = 0.61). Complete recanalization (mTICI 2c or 3) led to significantly better mRS outcomes at 90 days compared to mTICI 2b (median mRS 4 vs. 6, adjusted P = 0.038), with 26.8% functional independence and 37.8% mortality. In multivariable analysis, complete recanalization was significantly associated with better 90-day outcomes than mTICI 2b or lower recanalization (odds ratio 4.24 [95% Confidence interval 1.46–12.3]; P = 0.002), while the number of passes was not independently associated with worse outcomes (P = 0.98). For octogenarians, mTICI 2b recanalization yields limited clinical benefit and results in poor 90-day outcomes. In contrast, complete recanalization is independently associated with significantly better outcomes. Thus, once the decision is made to pursue EVT in the elderly, mTICI 2c or better recanalization should be the angiographic goal. Providers should not withhold thrombectomy passes based on age alone.

The paper presents the results of a simulation on a 3D model of undeformed chips and cutting forces during three-pass gear cutting using the power skiving method. At the level of individual blades and teeth in successive angular cutting positions, the main component of the cutting force and the tangential force on the cutter axis are shown. The analysis of the forces acting on a single gear tooth and the continuous cutting forces allowed the development of a methodology for the selection of rational cutting modes - the value of the axial feed, the number of passes with different cutting depths in order to ensure the minimum time consumption and to achieve the required accuracy of the gears in terms of the parameter of the permissible angular deviation of the profile of the cut gear. It is shown that, provided the required machining accuracy is ensured, higher productivity is achieved by increasing the axial feed at a lower depth of cut and increasing the number of passes, rather than by reducing the feed and increasing the depth of cut.

Within the institution of Transatlantic Slavery, across the Americas white enslaver control extended to the physical movement of those they held in bondage. This article adopts an extended conceptualization of creolization – the transformation of cultures, societies, and populations within the context of the contact between Europeans, enslaved Africans, and colonized and enslaved Indigenous peoples in the Americas – to explore the intersection of and conflicts between knowledge production and enslaved mobility. Through two case studies that analyse fugitive slave advertisements and the use of passes in the eighteenth-century British province of Quebec, I argue that these primary sources reveal evidence of a creolized counter-knowledge through which the enslaved resisted enslaver control through self-directed mobility in Canada.

Abstract: Leave passes provide authorized leave for hospitalized patients from a psychiatric inpatient unit. Although providing day passes was once a relatively common practice, there are relatively few data describing their safety and efficacy. This descriptive study examines the use of leave passes in an adult inpatient unit at a university hospital between 2017 and 2021, with attention to reasons for granting the day pass, duration, and outcome of the pass. During the study period, 10 patients with primary psychotic or mood disorders received 12 passes for housing coordination, COVID-19 vaccination, or major family events. There were no fatalities or abscondments. One patient experienced severe agitation and engaged in nonsuicidal self-injurious behavior. A second patient showed mild, redirectable psychomotor agitation upon return to the unit. The remaining 10 passes were uneventful. Our findings support the view that patients with diverse diagnoses can safely be provided leave from an inpatient setting with adequate planning and support, yielding a low incidence of adverse events.

The study detailed here has sought to assess the physical and technical activity engaged in by football players in the light of the direction of travel in which time zones were crossed as players transferred from training centres to match venues, in the context of matches played at the 2018 FIFA World Cup in Russia. The material consisted of 945 observations of 340 players. Analysed: total distances covered [km], distances covered with high-intensity running (20–25 km/h) [m], numbers of sprints, numbers of shots, numbers of passes, pass accuracy [%] and the official ranking of national teams. Three categories of time-zone shift (training centre → match venue) were taken account of, i.e. (1) West→East (WE), (2) Same Zone (SZ) and (3) East→West (EW). Analysis of results revealed that players in the EW and SZ categories were able to achieve results significantly better than those moving WE (total distances covered H = 11.815(2); p = 0.003; numbers of passes H = 7.630(2); p = 0.022), and this in relation to team placings in the end-of-tournament ranking (H = 18.099(2); p = 0.001). The results will be valuable in searching places for training centres during future FIFA World Cup and UEFA European Championship competitions. [ABSTRACT FROM AUTHOR]

The present study attempts to assess changes in soccer players' physical and technical activity profiles due to thermal stress, measured with the Universal Thermal Climate Index (UTCI), in training centres and during matches of the 2018 FIFA World Cup in Russia. The study also verifies the theoretical models of soccer players' physiological parameters. The study sample consisted of 945 observations of 340 players of national teams taking part in the World Cup in Russia. The measured variables included physical activities: total distance covered, distances covered with an intensity of 20–25 km/h, number of sprints; technical activities: number of shots, number of passes, pass accuracy and physiological indicators: evaporative water loss and heart rate. In addition, the final ranking places of each national team were also used in the study. The UTCI was calculated based on meteorological data recorded at training centres and during matches. The UTCI records were then classified into two ranges: NTS—no thermal stress (UTCI 9–26 °C) and TS—thermal stress (UTCI > 26 °C). Climatic conditions at soccer training centres assessed as involving "no thermal stress" are found to be more beneficial for increasing the total distance covered and the number of sprints performed by players during a match. The theoretical models for determining soccer players' physiological parameters used in the study reduce the players' heart rate effort and evaporative water loss, which is in line with findings in studies by other authors. The climatic conditions at soccer training centres and during tournament matches should be taken into account in planning preparations for future World Cup tournaments, especially those in hotter countries.

Peri-procedural blood loss and hemodilution occur in patients undergoing mechanical thrombectomy (MT) for ischemic stroke; however, its relationships with thrombectomy passes, procedure times, and clinical outcomes are unknown.Consecutive patients undergoing MT for anterior circulation large-vessel occlusion ischemic strokes were identified at a Comprehensive Stroke Center. Clinical information, modified treatment in cerebral ischemia (mTICI) scores, and modified Rankin Scores (mRS) at 90 days were prospectively collected from 2012 to 2021. Hemoglobin measurements before and after MTs were collected retrospectively via chart review, and changes were quantified. Patients with new-onset severe anemia (defined as post-MT hemoglobin less than 10g/dL) were identified. Modified Rankin scale (mRS) at 90 days was used to measure clinical outcomes.Four-hundred and forty-five patients were identified. Hemoglobin decreased 1.27 ± 1.05 g/dL after MT on average. Greater number of thrombectomy passes and longer procedure times were associated with larger decreases in hemoglobin (p < 0.001 and p = 0.002, respectively). 11.5% (51 of 445) of patients had new-onset severe anemia, and this incidence was significantly higher with more thrombectomy passes (6.4% for one pass, 11.9% for two passes, and 17.4% for three or more passes; p = 0.010). In multivariable analyses, new-onset severe anemia was associated with significantly higher odds of 90-day poor outcomes (mRS 3-6, OR 2.70 [95%CI 1.12–6.51], p = 0.027) and death (OR 2.73 [95%CI 1.06–7.04], p = 0.037) compared to mild post-MT anemia.More thrombectomy passes and longer procedure times were significantly associated with larger peri-procedural decreases in hemoglobin. Patients with new-onset hemoglobin less than 10 g/dL are at risk of poor outcomes. [ABSTRACT FROM AUTHOR]

The present study evaluated the effect of a smaller, lighter ball on kicking speed and technical- tactical and physical match performance in high-level adult female footballers. In the laboratory test setting, the peak ball velocity was 6 % higher with the new ball (NB) than the standard ball (SB) (26.5 ± 0.5 vs. 25.1 ± 0.5 m ⋅ s-1, p < 0.05). However, during match-play, no differences were observed in mean heart rate (87 ± 5 vs. 87 ± 5 %HRmax; p > 0.05), blood lactate (90 min: 4.7 ± 1.7 and 4.0 ± 1.7 mmol ⋅ l-1; p > 0.05), total distance covered (10.6 ± 0.9 and 10.4 ± 0.8 km; p > 0.05), intense running ( > 16 km/h) (2.08 ± 0.42 and 1.94 ± 0.38 km; p > 0.05) and match-induced decrement in Yo-Yo IR1 performance (28 vs. 31 %, respectively, p < 0.05) using NB compared to SB. Likewise, no difference was observed in the number of short, medium-range or long passes during matches played with the 2 ball types, and there was no difference in passing success rate (NB: 68 ± 1 % and SB: 68 ± 1 %, p > 0.05). In conclusion, high-level adult female footballers had a higher kicking speed when using a smaller, lighter ball, but no differences were observed during matchplay with the 2 ball types in respect of technicaltactical and physical match performance. The physical loading was high for the players when playing with both ball types. [ABSTRACT FROM AUTHOR]

Whether the use of more active teaching–learning methods has a positive impact on academic performance remains unanswered. This article seeks to contribute to the issue by conducting a study of an Operations Management course with almost 1000 students per year over three consecutive academic years. The study compares three scenarios with differing degrees of student involvement and Information Technology usage. The findings show no differences in terms of exam grades, but there is an increase in the percentage of passes in the most active scenario analysed, in which continuous assessment tests are used. Notwithstanding, student involvement in the optional assessable activities was found to be a significant factor for predicting the likelihood of passing the subject, especially when continuous assessment tests are used, since their grades show a higher correlation with exam grades.

A study is made of the effect of the degree of ovality of the passes in the finishing stands of an FQM mill on the accuracy and deformation characteristics of the rolled product with the use of a system of 384-mm passes. The transverse distribution of wall-thickness at the outlet of the deformation zone in the fourth and fifth stands is determined for different degrees of ovality of the finishing-stand passes. Relations are obtained to calculate the degree to which the mandrel is enveloped by the metal, the increase in the thickness of the semifinished product, and its spreading for different pass ovalities in the finishing stands of the FQM mill. It is established that it is best to regulate pass ovality in the leader stand in order to significantly improve the accuracy of the rolled pipe's geometric dimensions. [ABSTRACT FROM AUTHOR]

The aim of this research is to compare the game play variables in artificial turf vs. natural turf at high performance level and to assess in which manner it affects to the sport performance and the management of the facility. We analyzed 283 women players who participated in the FIFA® World Championship of 2011 (natural grass) and 483 women players of 2015 (artificial turf). Variables measured were passes, touches, dribbles, and tackles. We used U of Mann-Whitney test to evaluate the differences between two tournaments. Results showed that the success percentage of all game play actions is higher in artificial turf (World Championship 2015) in most of variables analyzed (except dribbles), in total and depending on player position.

Between 1916 and 1981, 17.25 million black South Africans were arrested for pass-law infringements. Though passbooks were pivotal texts in the lives of many South Africans, scholarship has focused mostly on their role in administering labour influxes. Thus the implications of having books facilitate state power have been largely unexplored. This article considers passbooks as books to examine how they narrated lives and conditioned various political and racial modes of subjectivity. It argues that despite passbooks’ unparalleled control over South Africans’ everyday lives, passbooks failed to mould all life stories into the rigid forms promulgated by apartheid doxa. Counter-narratives in black and ‘coloured’ writing of the period provide a useful framework for re-evaluating the role of reading and writing in the production of power. As interventions in the apartheid state’s monopoly of public discourse, such writing insisted that there be alternative ways of writing the apartheid subject into the archive.

The aim of this study was to examine the effect of playing formation on high-intensity running and technical performance during elite soccer matches. Twenty English FA Premier League games were analysed using a multiple-camera computerized tracking system (n = 153 players). Overall ball possession did not differ (P > 0.05) between 4-4-2, 4-3-3 and 4-5-1 formations (50%, s = 7 vs. 49%, s = 8 vs. 44%, s = 6). No differences were observed in high-intensity running between 4-4-2, 4-3-3 and 4-5-1 formations. Compared with 4-4-2 and 4-3-3 formations, players in a 4-5-1 formation performed less very high-intensity running when their team was in possession (312 m, s = 196 vs. 433 m, s = 261 vs. 410 m, s = 270; P < 0.05) but more when their team was not in possession (547 m, s = 217 vs. 461 m, s = 156 vs. 459 m, s = 169; P < 0.05). Attackers in a 4-3-3 performed ∼30% more (P < 0.05) high-intensity running than attackers in 4-4-2 and 4-5-1 formations. However, the fraction of successful passes was highest in a 4-4-2 (P < 0.05) compared with 4-3-3 and 4-5-1 formations. The results suggest that playing formation does not influence the overall activity profiles of players, except for attackers, but impacts on very high-intensity running activity with and without ball possession and some technical elements of performance.

We investigate the relation between the number of passes made by a football team and the number of goals. We analyze the 380 matches of a complete season of the Spanish national league "LaLiga" (2018/2019). We observe how the number of scored goals is positively correlated with the number of passes made by a team. In this way, teams on the top (bottom) of the ranking at the end of the season make more (less) passes than the rest of the teams. However, we observe a strong asymmetry when the analysis is made depending on the part of the match. Interestingly, fewer passes are made in the second half of a match, while, at the same time, more goals are scored. This paradox appears in the majority of teams, and it is independent of the number of passes made. These results confirm that goals in the first half of matches are more "costly" in terms of passes than those scored in second halves. [ABSTRACT FROM AUTHOR]

Passing is a common performance indicator in rugby since this action is performed by all players. Evaluating the indicators such as number of kicks, rucks, mauls, passes, and tries can provide valuable insight into team performance and may be used to predict the future performance of rugby union teams. Increases in passes, tackles, rucks, tries, and ball-in-play time were associated with the advent of professionalism Therefore, this study evaluated the number of passes during the 2013 Super rugby season and to determine if the number of passes discriminated between winning and losing teams. Data was gathered from 30 games during the 2013 Super Rugby season using the Verusco TryMaker Pro. Data collected were statistically analysed to show the number of kicks made during a season of Super Rugby. The results of this study suggest that losing teams tend to pass the ball more (157.41) than winning teams (127.02). In agreement with these results, winning teams have higher counts of kicks. The study shows a significant difference between winning teams and losing teams regarding total passes, bad passes, and good passes (p = <0.05). It can be concluded that factors such as the individual playing position, skill level of players, weather and game plan can determine the outcome of passing as a variable. Different teams use a variety of game plans and can influence the number of passes or kicks per match, and so also the outcome of the game. [ABSTRACT FROM AUTHOR]
