Calidad de vida, felicidad y satisfacción con la vida en personas ancianas de 75 años atendidas en un programa de atención domiciliaria

Se objetivó detectar los elementos que participan en la Calidad de Vida (CV) de las personas mayores de 75 años que reciben cuidados domiciliarios. El diseño fue de un estudio de caso. La muestra del estudio la configuraron las personas con 75 años o más, atendidos por el servicio de Atención Domiciliaria del Área Básica de Vilafranca del Penedès (n=26). Las variables fueron: a) datos socio demográficos, b) concepto de CV; c) percepción de CV, d) motivos; e) satisfacción con la vida y aspectos relacionados; f) sentimiento de felicidad. Se aplicó la técnica de la entrevista cara a cara. El 76,9% presentó una buena percepción de CV y los principales elementos relacionados fueron la salud, las relaciones familiares y sociales y la adaptación. La teoría de los roles y la teoría de la desvinculación explican el proceso de adaptación de estos individuos en esa etapa de la vida.

A bioinspired peptide scaffold with high antibiotic activity and low in vivo toxicity

Bacterial resistance to almost all available antibiotics is an important public health issue. A major goal in antimicrobial drug discovery is the generation of new chemicals capable of killing pathogens with high selectivity, particularly multi-drug-resistant ones. Here we report the design, preparation and activity of new compounds based on a tunable, chemically accessible and upscalable lipopeptide scaffold amenable to suitable hit-to-lead development. Such compounds could become therapeutic candidates and future antibiotics available on the market. The compounds are cyclic, contain two D-amino acids for in vivo stability and their structures are reminiscent of other cyclic disulfide-containing peptides available on the market. The optimized compounds prove to be highly active against clinically relevant Gram-negative and Gram-positive bacteria. In vitro and in vivo tests show the low toxicity of the compounds. Their antimicrobial activity against resistant and multidrug-resistant bacteria is at the membrane level, although other targets may also be involved depending on the bacterial strain.
