ResumoNesta pesquisa buscamos refl etir sobre as relações que os skatistas constroem em determinados espaços da região da Grande Florianópolis-SC, em específi co na pista de skate do bairro Trindade -a Trinda -, e no CT SKT -Projeto SKT -projeto que oferece aulas de skate. Foi investigada a apropriação do espaço, as relações de sociabilidade entre os indivíduos, a formação do habitus e a construção do campo skatista na cidade. Como possibilidade de aprofundamento e contribuição para com a área dos estudos em Educação, discutimos a noção de relação com o saber, e seus desdobramentos diante dos saberes do skatismo. Concluímos indicando a capacidade oferecida pelo estudo desta noção, em desenvolver tensionamentos no campo cientifi co, em especial, nas Ciências Sociais e da Educação. Palavras-chave:Skate.

Background Aortic valve stenosis is the most common adult valve disease in industrialized countries. The aging population and the increase in comorbidities urge the development of safer alternatives to the current surgical treatment. Sutureless bioprosthesis has shown promising results, especially in complex procedures and in patients requiring concomitant surgeries. Objectives Assess the clinical and hemodynamic performance, safety, and durability of the Perceval® prosthetic valve. Methods This single‐center retrospective longitudinal cohort study collected data from all adult patients with aortic valve disease who underwent aortic valve replacement with a Perceval® prosthetic valve between February 2015 and October 2020. Of the 196 patients included (mean age 77.20 ± 5.08 years; 45.4% female; mean EuroSCORE II 2.91 ± 2.20%), the majority had aortic stenosis. Results Overall mean cross‐clamp and cardiopulmonary bypass times were 33.31 ± 14.09 min and 45.55 ± 19.04 min, respectively. Mean intensive care unit and hospital stay were 3.32 ± 3.24 days and 7.70 ± 5.82 days, respectively. Procedural success was 98.99%, as two explants occurred. Four valves were reimplanted due to intraoperative misplacement. Mean transvalvular gradients were 7.82 ± 3.62 mmHg. Pacemaker implantation occurred in 12.8% of patients, new‐onset atrial fibrillation in 21.9% and renal replacement support was necessary for 3.1%. Early mortality was 2.0%. We report no structural valve deterioration, strokes, or endocarditis, and one successfully treated valve thrombosis. Conclusions Our study confirms the excellent clinical and hemodynamic performance and safety of a truly sutureless aortic valve, up to a 5‐year follow‐up. These results were consistent in isolated and concomitant interventions, solidifying this device as a viable option for the treatment of isolated aortic valve disease.

O trabalho investiga sentidos atribuídos ao futebol, considerando experiências extraescolares e mediações pedagógicas estabelecidas com alunos dos anos iniciais. Os dados indicam que as relações que as crianças estabelecem com o saber e com o aprender engendra elementos anteriores e exteriores às experiências vivenciadas na escola, associadas a família, renda, consumo, mídia, gênero, exclusão, habilidade, prazer, fama, rendimento, saúde, dor, medo, tempo livre e reconhecimento da Educação Física como disciplina escolar. Estes elementos, basilares na relação que as crianças estabelecem com o saber, sugerem a necessidade de colocar suas declarações no centro do planejamento, mediando a produção de novos sentidos para o futebol, na escola e fora dela.

Background Thrombocytopenia post transcatheter aortic valve implantation (TPPT) in its most severe manifestation is an independent predictor of mortality. However, mechanisms that favors TPPT remain unknown. Purpose To establish the prognostic value and risk factors of TPPT in a real-life population of patients treated with transcatheter aortic valve implantation (TAVI) in a tertiary hospital. Methods We analyzed retrospectively clinical, laboratory, echocardiographic and procedure-related variables from 203 consecutive patients, treated with TAVI between January 2019 and October 2021. Results This cohort had mean age of 82,3 ±5,9 years, 56% male, 83% hypertensive, 62% dyslipidemia, 35% diabetic, 20% chronic kidney disease, 22% chronic obstructive pulmonary disease, 32% coronary artery disease, 20% had previous ICP, 38% Atrial Fibrillation (AF), 18% peripheral arterial disease, 12% neurovascular disease, 23% history of cancer, 10% pacemaker carriers. 50% of TAVIs were balloon-expandable and 50% self-expandable. Mean procedure duration was 138 ±109min, size 26,6±3mm, contrast dose 233 ±88mL. During in-hospital stay 192/203 patients had TPPT. Platelets before TAVI, 187.000 (IQR 148.000-222.000) Vs a minimum post-TAVI (PlqMin) of 135.000 (IQR 105.000-164.000); P<0,05. Platelet fall (DeltaPlq) 48.000 ±38.000. We observed a Minimum Kidney clearance (ClMin) 46 ±20,75mL/min/m2, a maximum ultrasensitive Troponin-T (Tr-TusMax) 250 ±450 pg/L, a Maximum C Reactive Protein (PCRMax) 6,68 ±6,4, and a Minimum Hemoglobin (HbMin) 9,8 ±1,7 g/dL. 31/203 (15,3%) patients were exitus at the end of follow-up. We observed a non-lineal statistically significant association between TPPT quartiles and all-cause mortality (P<0,05): 21 exitus occurred in the extreme quartiles (1 and 4) while only 11 at the central ones (2 and 3). DeltaPlq was associated with PCRMax (Pearson 0,25; P<0,001), CliMin (Pearson -0,23; P0,005), HbMin (Pearson -0,27; P 0,001), AF. The only protective factor for DeltaPlq was history of previous ICP. Among exitus patients PlqMin was observed later than in survivors (3,5 vs 2,2 days; P<0,05). TPPT’s quartiles, previous ICP, time to PlqMin, HbMin, PCRMax and Tr-TusMax were the variables found to be independent associated with all-cause mortality (P<0,05). Conclusions The non-linear association between TPPT and mortality, the temporal relation between TPPT and mortality and the linear correlation between TPPT and HbMin and PCRMax suggest that late TPPT may have a mortality prognostic value through an increased risk of low Hb in the context of an increased inflammatory status. The fact that history of ICP was associated with les platelet fall suggests that revascularization, or ICP associated drug therapy, may confer protection against after TAVI mortality.

In this book, football leaves the field to play with the word. It leaves the field to return as a game between remembering and forgetting in ten essays by researchers interested in this theme. The book takes memory as a raw material to consider our reflections on football, this game and sport that reaches different stages of life. Going beyond the contours of the playing field and breaking the boundaries between inside and outside, before and after, past and present, child and adult, the authors expose forgotten features in this cultural practice that, often, find no place in the productions about this theme.

ResumoEste trabalho teve como objeto de estudo o investimento pedagógico do professor. Investigamos a trajetória e as práticas de uma professora que trabalha há treze anos na educação básica. Utilizamos a abordagem biográfica e etnográfica, com recurso à entrevista semiestruturada e observações de 24 aulas ministradas pela professora. As categorias sartreanas de projeto e desejo de ser e, também, o conceito de móbile que, segundo a escola soviética, dão sentido à atividade do sujeito, foram utilizados na análise dos dados referentes à sua trajetória e investimento pedagógico. Identificamos as mediações fundamentais na realização do seu projeto e as razões que a incitam a agir, num quadro permanente de adversidades e realizações. Palavras-chave:Existencialismo.
