Sprint, agility, strength and endurance capacity in wheelchair basketball players.

The aims of the present study were, firstly, to determine the reliability and reproducibility of an agility T-test and Yo-Yo 10 m recovery test; and secondly, to analyse the physical characteristics measured by sprint, agility, strength and endurance field tests in wheelchair basketball (WB) players. 16 WB players (33.06 ± 7.36 years, 71.89 ± 21.71 kg and sitting body height 86.07 ± 6.82 cm) belonging to the national WB league participated in this study. Wheelchair sprint (5 and 20 m without ball, and 5 and 20 m with ball) agility (T-test and pick-up test) strength (handgrip and maximal pass) and endurance (Yo-Yo 10 m recovery test) were performed. T-test and Yo-Yo 10 m recovery test showed good reproducibility values (intraclass correlation coefficient, ICC = 0.74-0.94). The WB players' results in 5 and 20 m sprints without a ball were 1.87 ± 0.21 s and 5.70 ± 0.43 s and with a ball 2.10 ± 0.30 s and 6.59 ± 0.61 s, being better than those reported in the literature. Regarding the pick-up test results (16.05 ± 0.52 s) and maximal pass (8.39 ± 1.77 m), players showed worse values than those obtained in elite players. The main contribution of the present study is the characterization of the physical performance profile of WB players using a field test battery. Furthermore, we demonstrated that the agility T-test and the aerobic Yo-Yo 10 m recovery test are reliable; consequently they may be appropriate instruments for measuring physical fitness in WB.

[Searching for evidence. A compilation of useful resources for health technology assessment]. / Búsqueda de evidencias. Una recopilación de recursos útiles en la evaluación de tecnologías sanitarias.

The spectacular growth in the produced volume of published scientific and technical information during the last years makes it difficult to discriminate and localize the information of greater quality. The parallel development of technologies for the fast handling of great volumes of single information has partially solved the problem of the access and use of the most advisable information. Health technology assessment tries to facilitate the decision making on the introduction, diffusion or use of health technologies, being based on the best evidences available. In order to improve the process of searching for evidences, needed in the process of health technology assessment, the Agency of Health Technology Assessment of the Institute of Salud Carlos III (AETS) made a compilation of information resources that can be useful for searching biomedical information in general. This article presents the above mentioned compilation along with the description of the process of elaboration and the criteria of selection applied.

[Report on the surgery for epilepsy]. / Informe sobre la cirugía de la epilepsia.

OBJECTIVE: We review the clinical indications and outcomes of surgical procedures in epilepsy which is resistant to medical treatment and the current situation and future possibilities of carrying out surgery for epilepsy in Spain. DEVELOPMENT: Search of the scientific literature included in the data base MEDLINE for the period 1995-1997, retrieval of reports in relation to agencies for the evaluation of health technology of the INAHTA network and the data base of the Cochrane library. The surgery of epilepsy reduces the frequency of seizures (the basic result analyzed) in all groups of patients, although in a very variable manner, depending on the clinical situation and type of operation. The results in patients with temporal lobe epilepsy and in those with localized lesions are particularly good (temporal lobe epilepsy and lesionectomy) (67-69% without seizures), with a follow up period of one to two years. It is estimated that in Spain between 75 and 300 new cases per year would benefit from surgery. The number of patients with drug-resistant epilepsy operated on in Spain is approximately 100-150 patients per year. CONCLUSIONS: Operations for epileptic syndromes, where there are surgically resectable lesions, should be justified by the gravity and impact of the disease on the psychosocial and functional development of the patient. Insufficiency resources are dedicated to the option of surgical treatment and perhaps they are also underused. These operations should be carried out in highly specialized centres, with adequate resources and an annual volume which guarantees excellence.

[Efficacy of the meningococcal vaccine from Group C capsular polysaccharide]. / Eficacia de la vacuna meningocócica de polisacárido capsular del grupo C.

BACKGROUND: This report is a systematic review of the effect intensity and duration of the immune response to meningococcal serogroup C vaccine. The vaccine safety, efficacy and effectiveness are also analyzed. METHODS: MEDLINE literature search in the period 1970-1996. Meningoccocal polysaccharide vaccine clinical trials and human prospective studies were specifically searched. Quality of the retrieved studies were analyzed. Information available was integrated. RESULTS: Group C meningoccal polysaccharide vaccine is a safe product. Its efficacy is over 85% among adults and children over 5 years old. 70% (CI 95%: 5-91%) under 5 years old, and 55% among children 2-3 years old. The vaccine is not effective under 2 years. The duration of protective antibody levels decrease with age. The proportion of vaccinated children effectively protected one year after vaccination is low. Vaccination does not affect the immune response to ulterior revaccination. CONCLUSIONS: Group C meningococcal polysaccharide vaccine is indicated in adults and children over 2 years old to protect them from meningococcal disease due to group C when exposed to high risk of infection. The outbreaks control is the main indication for the use of this vaccine. Routine immunization in not outbreak situation is not recommended due to the small vaccine protection in children under 2 years old, the limited efficacy in children under 5, and the short duration of the immunity in children.
