Neighbourhood benthic configuration reveals hidden co-occurrence social diversity.

Ecological interactions among benthic communities are crucial for shaping marine ecosystems. Understanding these interactions is essential for predicting how ecosystems will respond to environmental changes, invasive species, and conservation management. However, determining the prevalence of species interactions at the community scale is challenging.

[Adolescent use of helmets moped riders in the city of Gerona, Spain, 2006].

Background: Cerebral injuries as a result of craniocerebral trauma are the most frequent cause of death in traffic collisions involving two-wheeled vehicles. In spite of the proven effectiveness of the use of the head protective devices to prevent injuries in the event of traffic collisions, some teenagers and youngsters do not use it. The main goal of this research is to identify the best predictors of helmet use among adolescents.

Assessment of analysis of urinary pneumococcal antigen by immunochromatography for etiologic diagnosis of community-acquired pneumonia in adults.

The limitations of conventional microbiologic methods (CMM) for etiologic diagnosis of community pneumococcal pneumonia have made faster diagnostic techniques necessary. Our aim was to evaluate the usefulness of the immunochromatography (ICT) technique for detecting urinary Streptococcus pneumoniae antigen in the etiologic diagnosis of community-acquired pneumonias (CAP). This was a prospective study on in-patients with CAP in a tertiary hospital conducted from October 2000 to March 2004.

[Efficacy of an antibacterial filter for preventing contamination of respiratory function diagnostic equipment].

Objectives: Devices to assess lung function are a potential source of nosocomial infection. Our aims in this study were: 1) to determine the efficacy of an antimicrobial filter to prevent contamination of a multifunctional device; 2) to assess the ability of the filter to prevent cross contamination of individuals being tested; and 3) to evaluate the efficacy of the recommendations of the Spanish Society of Respiratory Diseases and Thoracic Surgery for disinfecting lung function equipment.

Design: In this prospective, randomized study in two phases we used filters in phase 1 but not in phase 2.
