RESUMEN
Under semiarid and warm climates, field practices for climate change adaptation have to be defined in order to modulate grape composition according to the desired wine styles. Under this context, the present study investigated several viticulture practices in cv. Macabeo for Cava production. The experiment was carried out over 3 years in a commercial vineyard located in the province of Valencia (eastern Spain). The techniques tested were (i) vine shading, (ii) double pruning (bud forcing), and (iii) the combined application of soil organic mulching and shading, all of them tested against a control. Double pruning significantly modified phenology and grape composition, improving the wine alcohol-to-acidity ratio and reducing the pH. Similar results were also achieved by shading. However, the shading strategy did not significantly affect yield, unlike double pruning, which reduced vine yield even in the year following its application. Shading alone or in combination with mulching significantly improved the vine water status, suggesting that these techniques can also be used to alleviate water stress. Particularly, we found that the effect of soil organic mulching and canopy shading on stem water potential was additive. Indeed, all the techniques tested were useful for improving wine composition for cava production, but double pruning is only recommended for premium Cava production.
RESUMEN
Se presenta un caso de listeriosis congénita que originó un síndrome de dificultad respiratoria y meningoencefalitis modificada por los antibióticos y hecha crónica, lo que se derivo en ventriculitis con piocéfalo. Se exponen algunas características clínicas de la paciente, así como la evolución, tratamiento, etc. Son revisados algunos aspectos epidemiologícos de la Listeria monocytogenes y se enfatiza en la importancia de su diagnóstico como causa de infección prenatal y del recién nacido. Queda destacada la utilidad clínica de algunos procederes pediátricos, tales como la punción ventricular, la transiluminación y la ventriculografía en la valoración de estos pacientes(AU)
