Incidence of injury and illness at the Beijing 2022 Paralympic Winter Games held in a closed-loop environment: a prospective cohort study of 7332 athlete days.

OBJECTIVE: To describe the epidemiology of injuries and illnesses sustained during the Beijing 2022 Paralympic Winter Games, organised in a closed-loop environment to adhere with COVID-19 restrictions. METHODS: Injuries and illnesses from all teams were recorded on a daily basis by team medical staff on a web-based form and by local organising committee medical (polyclinic) facilities and venue medical support. Duplicates recorded on both systems were removed. Incidence of injuries and illnesses are reported per 1000 athlete days (95% CI). RESULTS: 564 athletes (426 male and 138 female) representing 46 countries were monitored for the 13-day period of the Beijing 2022 Paralympic Winter Games (7332 athlete days). The overall incidences were 13.0 injuries (10.6-15.8) and 6.1 illnesses (4.5-8.4) per 1000 athlete days. The incidence of injury in alpine skiing (19.9; 15.2-26.1) was significantly higher compared with Nordic skiing, ice hockey and wheelchair curling (p<0.05), while the incidence of respiratory illness was significantly higher in Nordic skiing (1.6; 0.9-2.9) compared with alpine skiing, ice hockey and snowboarding (p<0.05). CONCLUSION: The incidence of both injury and illness at the Beijing 2022 Games were the lowest yet reported in the Paralympic Winter Games. The incidence of injury was highest in alpine skiing. These findings underscore the importance of ongoing vigilance and continued injury risk mitigation strategies to safeguard the well-being of athletes in these high-risk competitions. Respiratory illnesses were most commonly reported in Nordic skiing, which included the three cases of COVID-19 recorded at the games.

Incidence and burden of injury at the Tokyo 2020 Paralympic Games held during the COVID-19 pandemic: a prospective cohort study of 66 045 athlete days.

OBJECTIVE: To describe the epidemiology of injuries at the Tokyo 2020 Paralympic Games, including injuries sustained in the new sports of badminton and taekwondo. METHODS: Injury data were obtained daily via the established web-based injury and illness surveillance system (WEB-IISS; 81 countries, 3836 athletes) and local organising committee medical facilities (81 countries, 567 athletes). Univariate unadjusted incidences (injuries per 1000 athlete days with 95% CIs), injury proportion (IP, %) and injury burden (days lost per 1000 athlete days) are reported. RESULTS: A total of 4403 athletes (1853 women, 2550 men) from 162 countries were monitored prospectively during the 3-day pre-competition and 12-day competition periods (66 045 athlete days). 386 injuries were reported in 352 athletes (IP=8.0%) with an incidence of 5.8 per 1000 athlete days (95% CI 5.3 to 6.5). Football 5-a-side (17.2), taekwondo (16.0), judo (11.6) and badminton (9.6) had the highest incidence. There was a higher incidence of injuries in the pre-competition period than in the competition period (7.5 vs 5.4; p=0.0053). Acute (sudden onset) injuries and injuries to the shoulder (0.7) and hand/fingers (0.6) were most common. Injury burden was 10.9 (8.6-13.8), with 35% of injuries resulting in time loss from training and competition. CONCLUSION: Compared with previous Paralympic Games, there was a reduction in injury incidence but higher injury burden at the Tokyo 2020 Paralympic Games. The new sports of taekwondo and badminton had a high injury incidence, with the highest injury burden in taekwondo, compared with other sports. These findings provide epidemiological data to inform injury prevention measures for high-risk sports.

Incidence and burden of illness at the Tokyo 2020 Paralympic Games held during the COVID-19 pandemic: a prospective cohort study of 66 045 athlete days.

OBJECTIVE: To describe the incidence and burden of illness at the Tokyo 2020 Paralympic Games, which was organised with strict COVID-19 countermeasures. METHODS: Daily illnesses were recorded via the web-based injury and illness surveillance system (teams with their own medical staff; n=81), and local polyclinic services (teams without their own medical staff; n=81). Illness proportion, incidence and burden were reported for all illnesses and in subgroups by sex, age, competition period, sports and physiological system. RESULTS: 4403 athletes (1853 female and 2550 male) from 162 countries were monitored for the 15-day period of the Tokyo Paralympic Games (66 045 athlete days). The overall incidence of illnesses per 1000 athlete days was 4.2 (95% CI 3.8 to 4.8; 280 illnesses). The highest incidences were in wheelchair tennis (7.1), shooting (6.1) and the new sport of badminton (5.9). A higher incidence was observed in female compared with male athletes (5.1 vs 3.6; p=0.005), as well as during the precompetition versus competition period (7.0 vs 3.5; p<0.0001). Dermatological and respiratory illnesses had the highest incidence (1.1 and 0.8, respectively). Illness burden was 4.9 days per 1000 athlete days and 23% of illnesses resulted in time loss from training/competition>1 day. CONCLUSION: The incidence of illness at the Tokyo 2020 Paralympic Games was the lowest yet to be recorded in either the summer or winter Paralympic Games. Dermatological and respiratory illnesses were the most common, with the burden of respiratory illness being the highest, largely due to time loss associated with COVID-19 cases. Infection countermeasures appeared successful in reducing respiratory and overall illness, suggesting implementation in future Paralympic Games may mitigate illness risk.

Seed biometry: another functional trait in caatinga

Seed biometrics is an excellent tool for understanding environmental filters, species potential and dispersal, successional stages of communities and the dynamics used by seeds to germinate, establish and develop, thus constituting a functional trait of the species. We aim to understand the relationship between aspects of seed biometrics and other phenological traits, in order to infer contributions about functional strategies in Caatinga. Between September 2017 and January 2019, 10 individuals of Cenostigma pyramidale(Tul.) LP Queiroz, Commiphora lepthophloeos(Mart.) JB Gillett, Jatropha mollissima(Pohl.) Baill., Monteverdia rigida(Mart.) Biral. Pseudobombax marginatum(A.ST.-Hil) A. Robyns, Zizyphus joazeiroMart. were monitored for the selection of three seed collection matrices. From each matrix 100 seeds were collected, which after screening resulted in 35 intact seeds that were used to measure length, width, thickness and volume. Caatinga seeds are generally small, as a result of the environmental stresses of the Brazilian semiarid. The analyzed variables separated three groups in the PCA. We noticed that these groups evidenced the successional stages in the Caatinga. One group included M. rigidaand P. marginatum,which are late secondary. C. pyramidaleand C. lepthophloeosformed another group coincident with intermediate successional stages. J. mollissimaand Z. joazeiroformed a group of pioneer species in anthropized environments. Another finding was that the area was in secondary succession. Thepioneer species presented the largest seeds and this characteristic is associated with the need for nutrient reserve that allows the embryo to germinate and last for a longer period without the need for exogenous nutrients, an essential condition for the Caatinga. With the advancement of ecological succession and the establishment of a more consolidated plant community, competition for resources, the frequent dispersion vector type and the nature of the environmental stresses present, the seeds may be smaller.

Mozart, but not the Beatles, reduces systolic blood pressure in patients with myocardial infarction.

INTRODUCTION: Music reduces systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) in various clinical situations, but it is unclear whether these changes occur in post-infarction patients. AIM: The aim is to evaluate the effects of music on patients with acute myocardial infarction (MI). METHODS: We evaluated patients with MI and we measured SBP, DBP, HR and double product (DP) two times before the intervention and one time every fifteen minutes with an ambulatory blood pressure monitor. We divided the patients into 3 groups: a group listening to music by Mozart; another listening to a Beatles collection and a third one listening to the radio news. Outcomes were the change in mean SBP, DBP, HR and DP with intervention. RESULTS: We enrolled 60 patients (20 in each group). SBP was significantly reduced in the Mozart group (variation of ­7.2 ± 8.5 mmHg) compared to the Beatles group (­1.3 ± 6.2 mmHg) (P = 0.021) and the radio news group (0.6 ± 8.7 mmHg) (P = 0.003). DP was significantly reduced in the Mozart group compared with the News group (­668.5 ± 773.2 vs 31.6 ± 722.1 mmHg) (P = 0.006). There were no differences in DBP and HR. CONCLUSION: Patients with MI who listened Mozart had a reduction in SBP and DP compared to those who listened to the Beatles or the news.

Influence of implementation of a chest pain unit on acute coronary syndrome outcomes.

BACKGROUND: Different strategies have been described to increase promptness and efficiency in the assessment and management of patients with acute chest pain and acute coronary syndrome (ACS) in the emergency department (ED). OBJECTIVE: The objective of this study is to evaluate the results of implementing a Chest Pain Unit (CPU) to assist patients with ACS, and to determine its impact on quality of health care indexes and clinical outcomes. METHODS: A study was conducted with a prospective cohort of patients admitted to the ED with a chief complaint of acute chest pain or suspected ACS at two different time periods: before (n = 663) and after (n = 450) introducing a CPU as part of the ED. Quality-of-care indexes analyzed in this study were adherence to a critical pathway, length of hospital stay, and hospital mortality. RESULTS: There was increased adherence to a critical pathway during the CPU period compared to the period with no designated CPU area, including compliance with prescribing aspirin, beta-blockers, and angiotensin-converting enzyme inhibitor, and performing coronary angiography in high-risk patients. After adjustment to baseline characteristics, admissions to a CPU resulted in a 65% reduction in mortality (odds ratio 0.35; 95% confidence interval 0.14-0.88; p = 0.03). There was no difference in median length of hospital stay, 7 days (interquartile range [IQR] 4-12) before CPU and 6 days (IQR 4-11) after introducing the CPU (p = 0.10). CONCLUSION: In the scenario of a crowded ED, implementation of a CPU was associated with greater adherence to a critical pathway for patients with ACS, with a concomitant reduction in mortality rates.

[Echocardiographic assessment of cardiac resynchronization therapy: two-year follow-up period]. / Avaliação ecocardiográfica da terapia de ressincronização cardíaca: dois anos de seguimento.

BACKGROUND: The cardiac resynchronization therapy (CRT) is an effective option for patients with advanced heart failure (HF). Clinical, electrocardiographic and echocardiographic criteria have been studied in an attempt to find the patients that will benefit from the CRT, considering that the echocardiogram is the method that is used both in the selection and in the assessment of such therapy. OBJECTIVE: The objective of this work is to analyze the use of echocardiogram to assess the CRT, in a ten-day follow-up period and after two years of evolution. METHODS: The assessment considered 20 patients subjected to CRT, for a period of two years, 80% of which were male. The Minnesota Living with Heart Failure Questionnaire (MLWHF) was filled out. Patients underwent a six-minute walking test. Then, the two-dimensional echo-Doppler-cardiogram was performed. The initial assessment was repeated ten days after and two year after the implantation of the biventricular pacemaker. RESULTS: In two years, 5 patients (25%) died; 4 had cardiomyopathy caused by the Chagas's disease. There was no statistically significant change in the ejection fraction between the pre-operation period and the following ten days, but there was a significant change between the pre-operation period and two years after that, and the ten-day period and two years after that. In the ten-day follow-up period, there was the worsening of the intraventricular dyssynchrony, as evaluated by the tissue Doppler method, and the 'living with heart failure' score was higher in the group of deaths. CONCLUSION: Out of the echocardiographic parameters assessed, only the intraventricular dyssynchrony assessment through the tissue Doppler method, after the procedure, was capable of predict the CRT efficiency with respect to the death rate.

Fundamento: A terapia de ressincronização cardíaca (TRC) é uma opção efetiva para os pacientes com insuficiência cardíaca (IC) avançada. Critérios clínicos, eletrocardiográficos e ecocardiográficos têm sido estudados na tentativa de selecionar os pacientes que serão beneficiados com a TRC, sendo o ecocardiograma um método utilizado tanto na seleção quanto na avaliação desta terapêutica. Objetivo: O objetivo deste trabalho é analisar a utilização do ecocardiograma na avaliação da TRC, no seguimento de dez dias e após dois anos de evolução. Métodos: Foram avaliados 20 pacientes submetidos à TRC, por um período de dois anos, sendo 80 por cento do sexo masculino. Foi aplicado o Questionário de Qualidade de Vida de Minnesota, o teste de caminhada de seis minutos e realizado o ecodopplercardiograma bidimensional. Dez dias após o implante do marca-passo biventricular, bem como dois anos depois, foi repetida a avaliação inicial. Resultados: Em dois anos, 5 pacientes (25 por cento) foram a óbito; 4 apresentavam cardiomiopatia de etiologia chagásica. Não houve alteração estatisticamente significante da fração de ejeção entre o período pré-operatório e os dez dias seguintes, mas sim uma alteração significante nos períodos de pré-operatório e dois anos e de dez dias e dois anos. No seguimento de dez dias, houve piora da dissincronia intraventricular avaliada pelo Doppler tecidual, assim como a pontuação no escore de qualidade de vida foi maior no grupo óbito. Conclusão: Dos parâmetros ecocardiográficos avaliados, somente a avaliação da dissincronia intraventricular pelo Doppler tecidual após o procedimento foi capaz de predizer a eficácia da TRC em relação à mortalidade.

Estimación preliminar de la vulnerabilidad sísmica de los hospitales Carlos Van Buren y Dr. Gustavo Fricke

La vulnerabilidad sísmica de un centro hospitalario queda determinada por la capacidad de atención que pueden ofrecer sus servicios clínicos y de apoyo a la emergencia una vez ocurrido un sismo severo. El objetivo de este trabajo de título es aplicar una metodología de evaluación sísmica de centros hospitalarios usando como referencia los hospitales Carlos Van Buren de Valparaíso y Dr. Gustavo Fricke de Viña del Mar. Este estudio surge de la necesidad de conocer el estado actual del Sistema de Salud Pública de Chile ante la amenaza de eventos sísmicos. Para la evaluación de la vulnerabilidad estructural se utilizan metodologías cualitativas que se apoyan en una serie de índices globales aplicables a la estructura. La evaluación de la vulnerabilidad no estructural se basa en aspectos cualitativos considerando sus características propias, su interacción con el sistema estructural y su función de uso. La metodología fue aplicada sólo a algunas edificaciones de los hospitales, las cuales fueron seleccionadas de acuerdo a la importancia de los servicios que en ellas funcionan. De este estudio se concluye que la metodología empleada en estos centros hospitalarios permite detectar en forma preliminar aspectos vulnerables y no vulnerables en los servicios estudiados. (AU)

Estudo comparativo entre balão único de inoue e duplo balão na valvoplastia mitral percutânea. Resultados imediatos e após seguimento de um ano / Comparative study between inoue single balloon and double balloon in percutaneous mitral valvuloplasty. Immediate results and after 1 year follow-up

PURPOSE: To compare early and 12 months results of mitral stenosis (MS) correction by percutaneous balloon valvuloplasty (PMBV) using Inoue's single-balloon or double balloon techniques. METHODS: We submitted 139 consecutive patients to PMBV using Inoue single-balloon (n = 56, GI) or the double balloon technique (n = 83, GII). The two groups were similar, in: age, sex, functional class (FC), echocardiographic (ECHO) score, mitral valve area (MVA), and gradient (G) or presence of regurgitation. Clinical and ECHO data were compared before (PRE), immediately after (POI) and one year following the procedure (PO12M). RESULTS: PMBV was successfully performed in 53 (95) patients of GI and in 79 (96) of GII. Statistical analyses showed that the groups were similar at POI but different at PO12M (p < 0.002). ECHO immediately after PMBV showed that: MVA increased from 0.99 +/- 0.23 to 2.01 +/- 0.44cm2 (p < 0.001) in GI and from 0.94 +/- 0.23 to 2.09 +/- 0.35cm2 (p < 0.001) in GII and G decreased from 11.58 +/- 5.02 to 5.16 +/- 2.23mmHg (p < 0.001) in GI and from 12.48 +/- 4.89 to 5.96 +/- 3.21mmHg (p < 0.001) in GII. After one year 36 (64) patients in GI and 62 (74) in GII underwent an ECHO study. A comparison between immediate and one year follow-up results showed that MVA decreased from 2.01 +/- 0.4 to 2.00 +/- 0.3cm2 (NS) in GI and from 2.09 +/- 0.3 to 1.74 +/- 0.4cm2 (p < 0.001) in GII and G decreased from 5.16 +/- 2.2 to 5.50 +/- 2.9mmHg (NS) in GI and from 5.96 +/- 3.2 to 8.61 +/- 4.8mmHg (p < 0.001) in GII. There was therefore a sustained improvement of MVA and G after one year in GI and a significant decrease in MVA and G in GII. The FC after one year was similar and satisfactory in both groups. CONCLUSION: Both techniques are equally effective in relieving MS immediately after PMBV, but after one year, despite similar FC, Inoue-balloon technique seems to be superior to maintain MVA and G.

Objetivo - Comparar os resultados imediatos e de 12 meses das técnicas de duplo balão e do balão único de Inoue na correção da estenose mitral (EM) pela valvoplastia por cateter-balão (VMCB). Métodos - Submetemos 139 pacientes consecutivos, portadores de EM sintomática à VMCB. A técnica de Inoue foi utilizada em 56 pacientes (GI) e a do duplo balão em 83 (GII). Ambos os grupos eram semelhantes quanto a: idade, sexo, classe funcional (CF), escore ecocardiográfico, gradiente (G) e área valvar mitral (AVM), mitral (G) e pre sença de insuficiência mitral pela ecodopplercardiografia no pré-VMCB (PRE). Analisaram-se dados clínicoecocardiográficos, no PRE, logo após-VMCB (POI) e em 12 meses (PO12M). Resultados - A VMCB foi considerada com sucesso em 53 (95%) pacientes do GI e em 79 (96%) do GII. Análise estatística revelou que os grupos eram semelhantes no POI e diferentes no PO12M (p< 0,002). Os resultados no POI mostraram que a média da AVM (cm2) aumentou de 0,99 ± 0,23 para 2,01 ± 0,44 (p< 0,001) no GI e de 0,94 ± 0,23 para 2,09 ± 0,35 (p<0,001) no GII, o G (mmHg) diminuiu de 11,58 ± 5,02 para 5,16 ± 2,23 (p<0,001) no GI e de 12,48 ± 4,89 para 5,96 ± 3,21 (p<0,001) no GII. No PO12M, 36/53 (64%) pacientes no GI e 62/79 (74%) no GII realizaram acompanhamento clínico-ecocardiográfico. A comparação entre POI e PO12M mostrou: a) AVM de 2,01 ± 0,4 x 2,00 ± 0,3 (NS) no GI e de 2,09 ± 0,3 x 1,74 ± 0,4 no GII (p<0,001); b) G de 5,16 ± 2,2 x 5,50 ± 2,9 (NS) no GI e de 5,96 ± 3,2 x 8,61 ± 4,8 (p<0,001) no GII; c) no GI, dos 4 (11%) pacientes que estavam em CF II e 32 (89%) em CF III/IV no PRE, todos evoluíram para CF I/II no POI e permaneceram nesta CF no PO12M, de forma similar no GII, dos 12 (19%) pacientes que estavam em CF II e 50 (81%) em CF III/IV no PRE, todos menos um evoluíram para CF I/II no POI e permaneceram nesta CF no PO12M. Conclusão - As duas técnicas são igualmente efetivas no POI, todavia no PO12M, a técnica de Inoue mostrou-se superior na manutenção de AVM e G

Valvoplastia mitral percutanea utilizando o cateter balao Inoue: resultados imediatos e seguimento de 1 ano / Ballon mitral valvoplasty using Inoue ballon: immediate results and one year follow-up

Os autores objetivaram avaliar resultados imediatos e seguimento de um ano da valvoplastia mitral por cateter-balao (VMCB) utilizando o balao Inoue, em 40 pacientes portadores de estenose mitral (EM) sintomaticos e consecutivos, submetidos a VMCB; 37 mulheres, media etaria de 36 (22-67 anos), cinco portadores de ReEM. Trinta e sete estavam em classe funcional III/IV (NYHA) e a VMCBN foi realizada de urgencia em seis pacientes, devido a edema agudo dos pulmoes, incluindo duas gestantes. Foram analisados os dados hemodinamicos no pre e no pos-VMCB imediato e os dados ecodopplercardiograficos (ECO) no pre, pos imediato (POS) e apos 12 meses de seguimento (PO12M). Os resultados hemodinamicos pre X pos foram: gradiente mitral (G)17,6+/-7,6X6,3+/-5,5mmHg; area valvar mitral (AVM) 0,89+/-0,25X1,66+/-0,63cm2; pressao media do atrio esquerdo 25,5+/-9,0X14,3+/-6,4mmHg; pressao media de arteria pulmonar 34,8+/-13,0X23,8+/-10,8mmHg (todos p<0,0001) e indice cardiaco 2,8+/-0,5X2,9+/-0,8l/min/m2 (NS). Tres pacientes apresentaram insuficiencia mitral (IM) moderada, na ventriculografia esquerda pos-VMCB. As complicacoes relacionadas diretamente ao procedimento foram: 2 casos com tamponamento cardiaco necessitando drenagem cirurgica, 3 com comunicacao inter-atrial e 1 com perfuracao de aorta, sem tamponamento cardiaco. Um paciente apresentou acidente vascular cerebral, 72 horas apos a VMCB sem sequela motora. Houve 2 insucessos, sendo que 1 evoluiu para obito 2 meses apos VMCB. Os 29 pacientes que foram efetivamente acompanhados por um periodo de 12 meses nao apresentaram eventos cardiacos; os resultados do ECO PRE X POS X PO12M foram: AVM 1,00+/-0,24X2,12+/-0,33 e G 11,1+/-5,0+/-2,0X5,3+/-2,6. Todos os pacientes estavam em classe funcional I/II apos um ano de seguimento. Portanto, o balao Inoue mostra bons resultados imediatos e no seguimento por um periodo de 12 meses e serve como opcao terapeutica para EM em pacientes sintomaticos selecionados
