Assessment of Risk Factors for Injuries on Beaches

The purpose of this study was to examine the risk factors for injuries on a beach. It is important to know all the risk fctors for injuries that can happen in a beach in order to prevent accidents. Risk factors were grouped in four main categories: beach morphology (BM), beach equipment (BE), lifeguard service (LS) and miscellaneous aspects (MA). All of them were evaluated according to their importance using a survey by Spanish and International experts. Descriptive analysis showed that LS is the main mechanism by which to reduce injuries on a beach. Lifeguard service in-service training is very important as are the affluence and activities developed by the beach patrons, the influences of weather and climate on the beach and other infrastructures as risk factors for dangers on beaches

THROWING VELOCITY IN ELITE WATER POLO FROM DIFFERENT AREAS OF THE SWIMMING POOL

The aim of this study is threefold: 1) To identify the throwing velocity during a match; 2) to identify possible differences in throwing velocities between male and female players; 3) to determine shot velocity from different zones of the court during real competition. We analyzed the water polo world championship. In order to evaluate the precise strength production, a radar gun was used. A one-way analysis of variance was applied (ANOVA) to study differences among playing areas. In addition, a t-Test for repeated measures was employed to compare different groups. This study identifies three major zones of goal shot. We identified the highest throwing velocity zones and the zones with highest shot number. In addition, the results show that the penalty shot is the fastest shot

Analysis of Self-Determined Motivation in Basketball Players through Goal Orientations

The purpose of this study was twofold. Firstly to examine the relations between the different constructs that defines Nicholls’ Achievement Goal Theory and Deci and Ryan’s self-determination theory. Secondly to analyse the differences that exist between them with respect to the socio-demographic variables gender and age. A sample of 292 federated basketball players from the Region of Murcia (Spain) with ages between 14 and 18 years old was used. In addition, Castilian versions of The Perception of Success Questionnaire (POSQ) and the Sports Motivational Scale (SMS) were administered. Three statistical analyses were employed, a descriptive analysis, a correlation analysis and a regression analysis. The results showed a positive relation between ego orientation, extrinsic motivation and amotivation. The motivational relations between both theories and the differences with respect to gender and age are discussed.We have found out that mainly gender and also age differences are strong predictors of ego orientation, extrinsic motivation of external regulation and amotivation. We can also confirm that extrinsic motivation of external regulation positively predicts ego orientation and a decrease of task orientation. The results ratify the use of the Spanish version of the SMS to measure different types of motivation within the sports context

Motives of practice in the field of non-competitive physical activity

Resumen basado en el de la publicaciónSe analizan cuáles son los motivos de práctica en el ámbito de la actividad física no competitiva. Para ello se administró la escala de medición de los motivos de actividad física revisada (MPAM-R, Motives for Physical Activity Measure-Revised) de Ryan, Frederick, Lepes, Rubio y Sheldon (1997) y validada en España por Moreno, Cervelló y Martínez (2007) a una muestra compuesta por 271 sujetos adultos practicantes de actividades físicas no competitivas. Se realizó un análisis factorial de componentes principales de la escala y un análisis de correlación de las distintas subescalas. Los resultados manifiestan que las principales razones para realizar actividades físicas son el fomento de las relaciones sociales así como la obtención de placer y diversión, por delante de otras como la competencia, el mantenimiento y mejora de la salud y la apariencia.AndalucíaES

Goal orientations, satisfaction, beliefs in sport success and motivational climate in swimmers.

En el presente estudio se plantearon varios objetivos; comprobar las relaciones existentes entre las orientaciones de meta, la satisfacción, las creencias sobre las causas del éxito en el deporte y el clima motivacional percibido en nadadores; examinar el efecto que tiene la orientación de meta en las diferentes dimensiones analizadas; y, por último, predecir la orientación de meta. La muestra estuvo compuesta por 163 nadadores. Los instrumentos utilizados fueron las versiones validadas al castellano del TEOSQ, SSI, BACSSQ y PMCSQ-2. Se realizaron tres tipos de análisis estadísticos: análisis de correlaciones bivariadas, análisis multivariante (MANOVA 2x2) y análisis de regresión lineal múltiple multivariado por pasos. Los resultados mostraron que la capacidad y el aburrimiento son variables predictoras de la orientación de meta hacia el ego, mientras que el esfuerzo y la diversión lo son de las orientaciones de meta hacia la tareaThe present study had several objectives; to check the relationships between goal orientations, satisfaction, beliefs about the causes of success in sport and motivational climate perceived in swimmers; to examine the effect of goal orientation in different dimensions analyzed, and finally to predict goal orientation. The sample consisted of 163 swimmers. The instruments used were validated to Castilian versions of TEOSQ, SSI, BACSSQ and PMCSQ-2. There were three types of statistical analyzes: bivariate correlation analysis, multivariate analysis (MANOVA 2x2) and multiple linear regression analysis stepwise multivariate. The results showed that capacity and boredom are predictors of goal orientation towards the ego, while effort and fun are the goal orientations to the tas

Lactate and Number of Organ Failures Predict Intensive Care Unit Mortality in Patients with Acute-on-Chronic Liver Failure

Background and aims: Patients with acute-on-chronic liver failure (ACLF) have high mortality rates. Most prognostic scores were not developed for the intensive care unit (ICU) setting. We aimed to improve risk stratification for patients with ACLF in the ICU. Methods: A training set with 240 patients with cirrhosis and organ failures (Chronic Liver Failure Sequential Organ Failure Assessment score [CLIF-SOFA]) from Curry Cabral Hospital (Portugal) and University of Alberta Hospital (Canada) in 2010-2016 was used to derive a prognostic model for ICU mortality. A validation set with 237 patients with cirrhosis and organ failures from Vancouver General Hospital (Canada) in 2000-2011 was used to evaluate its performance. Results: Amongst patients in the training set, ICU and hospital mortality rates were 39.2% and 54.6% respectively. Median lactate (4.4 vs 2.5 mmol/L) and number of organ failures (3 vs 2) on admission to ICU were associated with higher likelihood of ICU mortality (P < 0.001 for both). The lactate and organ failures predictive model (LacOF) was derived to predict ICU mortality: -2.420 + 0.072 × lactate + 0.569 × number of organ failures (area under-the-curve [AUC], 0.76). In the validation set, the LacOF model discriminative ability (AUC, 0.85) outperformed the CLIF-SOFA (AUC, 0.79), Chronic Liver Failure Consortium Acute-on-Chronic Liver Failure (AUC, 0.73), Model for End-stage Liver Disease score (AUC, 0.78) and Acute Physiology and Chronic Health Evaluation II scores (AUC, 0.74; P < 0.05 for all). The LacOF model calibration was good up to the 25% likelihood of ICU mortality. Conclusions: In patients with ACLF, lactate and number of organ failures on admission to ICU are useful to predict ICU mortality. This early prognostic evaluation may help to better stratify the risk of ICU mortality and thus optimize organ support strategies.info:eu-repo/semantics/publishedVersio

Economic burden of age-related macular degeneration in routine clinical practice: the RAMDEBURS study

Purpose: To describe and evaluate the main direct health costs, in routine clinical practice, of age-related macular degeneration (AMD) patients, from hospital perspective, in Spain. Methods: Retrospective, multicenter, and observational study conducted on five third-level Spanish hospitals, between December 2018 and December 2019. The study included patients who were diagnosed of AMD before December 2018. Direct healthcare costs were obtained from a Spanish database. Study variables included demographic and clinical variables, and resources, such as treatment, diagnostic tests, medical examination, and surgery. Among the 1414 screened AMD patients, 1164 patients were included. In the overall study patients, the total cost was €5,386,511.0, with a mean cost per patient of €4627.6 ± 2383.9. The largest cost items were diagnostic examinations (€2.832.902,0) and vascular endothelial growth factor inhibitors (anti-VEGF) treatment (€2.038.257,2). Bevacizumab was administered to 325 (27.9%) patients, ranibizumab to 328 (28.2%), and aflibercept to 626 (53.8%); 115 (10.7%) patients received two anti-VEGF treatments, while 90 (7.7%) did not receive any. Over the course of the study, a total of 6,057 anti-VEGF injections were administered, with a mean (95% confidence interval) of 4.8 (4.4-5.2) injections per patient. Regarding safety, 29 patients experience injection-related adverse events, among them 12 patients had cataract and 11 ones elevated intraocular pressure (IOP). The incidence of endophthalmitis was 0.5% (6/1164). Conclusions: AMD was associated with considerable healthcare costs for regional healthcare systems. Diagnostic examinations, particularly OCT examinations, and anti-VEGF treatment represented the largest cost items

We assessed the association of MDR colonization and MDR infection with these patients' survival. Observational cohort study including adult cirrhosis patients admitted to 5 intensive care units at Northwestern Memorial Hospital (Chicago, Illinois, USA) on January 1, 2010, to December 31, 2017. Patients admitted for elective liver transplant or with previous liver transplant were excluded. Patients were screened for MDR colonization on intensive care unit admission. Infection diagnoses during the intensive care unit stay were considered. The primary endpoint was hospital transplant-free survival. Among 600 patients included, 362 (60%) were men and median (interquartile range) age was 58.0 (49.0, 64.0) years. Median (interquartile range) Model for End-stage Liver Disease, Sequential Organ Failure Assessment, and Chronic Liver Failure-Acute-on-Chronic Liver Failure scores on intensive care unit day 1 were 28.0 (20.0, 36.0), 9.0 (6.0, 13.0), and 55.0 (48.0, 64.0), respectively. Overall, 76 (13%) patients were transplanted and 443 (74%) survived the hospital stay. Infections were diagnosed in 347 (58%) patients: pneumonia in 197 (33%), urinary tract infection in 119 (20%), peritonitis in 93 (16%), bloodstream infection in 99 (16%), Clostridium difficile colitis in 9 (2%), and catheter tip infection in 7 (1%). MDR colonization and MDR infection were identified in 200 (33%) and 69 (12%) patients, respectively. MDR colonization was associated with MDR infection (p < 0.001). MDR colonization or MDR infection was associated with higher number and duration of antibiotics (p < 0.001). Following adjustment for covariables (age, sex, etiology, portal hypertension, and Sequential Organ Failure Assessment score), MDR colonization [OR (95% CI), 0.64 (0.43, 0.95)] or MDR infection [adjusted OR (95% CI), 0.22 (0.12, 0.40)] were independently associated with lower transplant-free survival. Among critically ill cirrhosis patients, MDR colonization or MDR infection portended a worse prognosis.publishersversionpublishe

A Randomized Study of Nutritional Supplementation in Patients with Unilateral Wet Age-Related Macular Degeneration

Carotenoides; Marcadors inflamatoris; Àcids grassos poliinsaturatsCarotenoides; Marcadores inflamatorios; Ácidos grasos poliinsaturadosCarotenoids; Inflammatory markers; Polyunsaturated fatty acidsThe purpose of this study is evaluate the efficacy and safety of medicinal products containing the original Age-Related Eye Disease group (AREDS) formulation at doses approved in Europe (EU, control group; n = 59) with a product that adds DHA, lutein, zeaxanthin, resveratrol and hydroxytyrosol to the formula (intervention group; n = 50). This was a multicenter, randomized, observer-blinded trial conducted in patients aged 50 years or older diagnosed with unilateral exudative Age related Macular Degeneration AMD. At month 12, the intervention did not have a significant differential effect on visual acuity compared with the control group, with an estimated treatment difference in Early Treatment Diabetic Retinopathy Study (ETDRS) of −1.63 (95% CI −0.83 to 4.09; p = 0.192). The intervention exhibited a significant and, in most cases, relevant effect in terms of a reduction in some inflammatory cytokines and a greater improvement in the fatty acid profile and serum lutein and zeaxantin concentration. In patients with unilateral wet AMD, the addition of lutein, zeaxanthin, resveratrol, hydroxytyrosol and DHA to the AREDS EU recommended doses in the short-term did not have a differential effect on visual acuity compared to a standard AREDS EU formula but, in addition to improving the fatty acid profile and increasing carotenoid serum levels, may provide a beneficial effect in improving the proinflammatory and proangiogenic profile of patients with AMD.The research was funded by Laboratorios Théa (Barcelona, Spain) and by research grants from the “Instituto de Salud Carlos III/European Regional Development Fund (ERDF)” and RD16/0008/0011, OFTARED: Enfermedades oculares: “Prevención, detección precoz, tratamiento y rehabilitación de las patologías oculares”
