Water Polo Performance Classification Based on the Functional Test for Agility Performance: A Long-Term Training Tool

Background: Water polo is an open-skilled team sport in which agility is important. Objective: This study aimed to propose a water polo player classification based on the Functional Test for Agility Performance. Methods: A total of 78 male water polo players of different competition levels (7.7% regional, 52.5% national and 39.7% international), years of training (6.7 ± 4.5; 2-25 years), weekly training frequency (6.1 ± 2.1; 2-12) and age (18.1 ± 4.3; 12-36) were evaluated in the Functional Test for Agility Performance. Hierarchical Cluster Analysis was used in five levels to classify water polo player performance. Results: The players were classified based on the Functional Test for Agility Performance as excellent (≤ 3.22 s), very good (3.23-4.48 s); good (4.49-4.76 s); under development (4.77-5.11 s) and learning (≥ 5.12 s). Age, years of training, and weekly training frequency showed a decreasing trend from Gr1 to Gr4. Athletes at the international level ranked primarily in the best performing groups (Gr1 and Gr2, n = 30), the ones at the national level in the intermediate groups (Gr2, Gr3 and Gr4; n = 41), with a higher concentration in Gr2, and those at regional level mainly in Gr4 (n = 4). Conclusion: This classification proposal is expected to be useful as a tool to evaluate the training of athletes of different competition levels as well as to follow up on water polo athletes in long-term training.

This study evaluates the contribution of a UK counter-terrorism training tool, the Project ARGUS simulation exercise format, designed to increase preparedness by ‘alerting not alarming’ the populace to the prevailing ‘severe’ international terrorist threat. The paper draws upon the theoretical basis for preparedness in order to contend that, despite exceeding expectations in terms of quantity of events delivered and evidence of immediate post-event learning, Project ARGUS does not wholly live up to its promise to change the behaviour of individuals and organisations by embedding long-term learning. The researchers designed and analysed pre- and post-event questionnaires (N = 120) in order to explore the impact of attendance at an ARGUS Retail event within a shopping centre. This information was then augmented with a follow-up survey (N = 44) and semi-structured interviews (N = 9) of key facilitators and participants. The authors recommend the immediate adoption of an appropriate evaluation and certification scheme to mandate participation and embed organisational learning. They argue that adoption of these approaches would better enable ARGUS to fulfil its potential and make a significant contribution to improving the resilience of busy crowded places to terrorism in the UK.

Heller's Myotomy

IntroductionAchalasia is a disorder characterised by failed relaxation of the lower oesophageal sphincter. The aim of this study was to examine, at a national level, the long-term outcomes of achalasia therapies.MethodsHospital Episode Statistics include diagnostic and procedural data for all English National Health Service–funded hospital admissions. Subjects with a code for achalasia who had their initial treatment between January 2006 and December 2015 were grouped by treatment; pneumatic dilatation (PD) or surgical Heller’s myotomy (HM). Procedural failure was defined as time to a further episode of the same therapy or a change to a different therapy. Up to three PDs were permitted without being considered a therapy failure.Results6938 subjects were included; 3619 (52.2%) were men and median age at diagnosis was 59 (IQR 43–75) years. 4748 (68.4%) initially received PD and 2190 (31.6%) HM. The perforation rate following PD was 1.6%. Mortality at 30 days was 0.0% for HM and 1.9% for PD, and <8% after perforation following PD. Factors associated with increased mortality after PD included age quintile 66–77 (OR 4.55 (95% CI 2.00 to 10.38), p<0.001), >77 (9.78 (4.33 to 22.06), p<0.001); Charlson comorbidity score >4 (2.87 (2.08 to 3.95), p<0.001); previous HM (2.47 (1.33 to 4.62), p<0.001); and repeat PD 1–3 (1.58 (1.15 to 2.16), p=0.005), >3 (1.97 (1.21 to 3.19), p=0.006). Durability of up to 3 PD and HM over 10 years of follow-up was 86.2% and 81.9%, respectively (p<0.001).DiscussionThe efficacy of PD for achalasia appears to be greater than HM over 10 years. There was no mortality associated with HM, but 1.9% of subjects died within 30 days of PD. Mortality was associated with increasing age, comorbidity, previous HM and repeat PD.

Political Decisions

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

AbstractA long-term photographic search programme for minor planets was begun at the Kleť Observatory at the end of seventies using a 0.63-m Maksutov telescope, but with insufficient respect for long-arc follow-up astrometry. More than two thousand provisional designations were given to new Kleť discoveries. Since 1993 targeted follow-up astrometry of Kleť candidates has been performed with a 0.57-m reflector equipped with a CCD camera, and reliable orbits for many previous Kleť discoveries have been determined. The photographic programme results in more than 350 numbered minor planets credited to Kleť, one of the world's most prolific discovery sites. Nearly 50 per cent of them were numbered as a consequence of CCD follow-up observations since 1994.This brief summary describes the results of this Kleť photographic minor planet survey between 1977 and 1996. The majority of the Kleť photographic discoveries are main belt asteroids, but two Amor type asteroids and one Trojan have been found.
