ABSTRACT
Objective: Evaluate auditory results and communicative benefits in adult patients with single-sided deafness (SSD) treated with cochlear implantation.Study Design: Observational descriptive case series.Setting: Hospital Universitario Fundación Santa Fe de Bogotá.Patients: Ten patients with profound post-lingual SSD were treated with cochlear implantation between January 2011 and March 2016. Two patients were excluded because of incomplete follow-up.Interventions: Medical records included demographic information, pre and post-operative audiometric results, and binaural and monoaural speech discrimination tests in three sound-in-noise configurationswith the cochlear implant turned on and off, respectively. Subjective improvement was evaluated using the Abbreviated Profile of Hearing Aid Benefit (APHAB) and Speech, Spatial, and Qualities of Hearing Scale (SSQ-B).Main Outcome Measures: Pre and post-operative audiometric and speech discrimination results, post-operative binaural and monoaural speech discrimination in noise results, and APHAB and SSQ-B questionnaire results.Results: Significant improvement in speech discrimination in a noisy environment was found when the noise and signal were presented from the front, and when the signal was presented to the implanted ear and the noise to the healthy ear. SSQ-B questionnaire showed improvement in all subscales, while APHAB showed improvement in all subscales except sound aversion.Conclusion: Patients with SSD showed improvement regarding communication skills and sound discrimination in a noisy environment.

We report on the first comprehensive DNA barcoding survey of bats from Jamaica and compare the genetic variation to similar species on South America and Central America. Bats comprise the majority of mammalian diversity in typical lowland forest in the Neotropics, but the Caribbean is one noticeable geographic gap in the International Barcode of Life reference database. Of the 20 known species reported from Jamaica, half were DNA barcoded and were genetically distinct with interspecific variation ranging from 17 to 33%. By contrast, intraspecific variation ranged from 0 to 0.5% indicating that the barcode gap was sufficient in differentiating bat species diversity in Jamaica. The low levels of intraspecific divergence indicate that the populations within each species are relatively homogeneous across the island. There were, however, several cases of high sequence divergence for widely distributed species that occur on both the Caribbean islands and the continental mainland, which warrant further taxonomic study.

Introduction: Heart diseases are a frequent cause of illness and death in our country. There is enough scientific evidence that shows that healthy life styles prevent the appearing of those diseases. Objective: To establish the frequency of exposition to risky factors concerning heart diseases for HealthSciences School's students, aiming to acquire information that helps in the development of strategies foravoiding those factors.
