Assessment of seabed litter at Concepción Seamount (Canary island) using a remotely operated towed vehicle.

The seafloor is recognised as a major sink for marine litter. However, studies conducted in this compartment addressing marine litter densities and its interactions with fauna are scarce, mainly due to sampling constraints. In this paper, we assess marine litter density, composition and interactions with marine communities and evaluate its relationship with fishing activities at the "Banco de la Concepción" seamount (Canary Islands, Spain). We took advantage of underwater video records taken with a Remotely Operated Towed Vehicle in the framework of the LIFE IP INTEMARES project. A total of 56 video transects were analysed covering about 9 km with 19 h of video recording. Transects were categorised as high, low, and null fishing effort based on the Vessel Monitoring System (VMS) positional data registered between 2009 and 2017. Litter items were recorded in 70% of the transects with a mean density of 2122 (±2464) items km-2. There were significant differences in litter densities over the three levels of fishing pressure, with a density decrease from stations of high to stations of null fishing pressure. Regarding categories, plastic was by far the most abundant category found (83.1%), mainly consisting of fishing lines, both monofilaments and entangled longlines. The study of the interactions of marine litter with fauna showed that less than 20% of the items presented an interaction with benthic organisms either by causing or not a visible impact. The sponge Asconema setubalense accounted for more than half (57.4%) of all interactions, but only 5% of all A. setubalense specimens showed physical damage.

[Clinical effect of a sustained-release theophylline formulation in moderate or severe asthmatic patients with intercrisis]. / Efecto clínico de una formulación de teofilina de liberación sostenida en pacientes asmáticos moderados o severos con intercrisis.

The clinical effect of the formulation of theophylline of sustained action was evaluated (Aristegui 300 mg, capsules) to the dose of 9 weight/day mg/kg (every 12 hours) in the consultation of bronchial asthma of Hospital Docente Provincial Clínico Quirúrgico de Santa Clara, in the understood period of February to September of 1997. The time of treatment was of one month and they were carried out five consultations. The sample was constituted by 30 asthmatic, moderate or severe patients. The variables were analyzed: attendance to guard's body, salbutamol use in spray and they were carried out objective mensurations from the lung function to all the patients in the different consultations. With the use of the formulation they diminished the flow expiratory pick significantly, the expiratory volume forced in one second and the flow half expiratory maximum and low incidence of adverse effects existed.

Poliarteritis nudosa con hemorragia retropertoneal espontanea, bilateral. Presentación de un caso

La Poliarteritis nudosa (PAN) es una vasculitis necrotizante sistémica de pequeñas y medianas arterias musculares carente de signos y síntomas patógnomonicos, aunque con posibilidad potencial de afectación de todos los organos parenquimatosos. (AU)

Principios farmacológicos de las drogas utilizadas en el Asma Bronquial

El trabajo tiene como objetivo fundamental revisar algunos aspectos farmacológicos útiles para el manejo de los medicamentos antiasmático, de uso común en nuestro medio, así como algunas drogas de aparición reciente y que poseen buena aceptación internacional y que dado nuestro desarrollo en la esfera de la salud pudieran formar parte, en un futuro cercano del arsenal terapéutico en el Asma Bronquial.
