Realization of polyaspartamide-based nanoparticles and in vivo lung biodistribution evaluation of a loaded gucocorticoid after aerosolization in mice
2016
Abstract In this study, novel polymeric nanoparticles (NPs) were developed and their potential as carriers for beclomethasone dipropionate (BDP) into the lung after aerosolization was demonstrated by in vivo studies in mice. In particular, these NPs were obtained starting from two polyaspartamide-based copolymers which were synthesized by chemical reaction of α,β-poly(N-2-hydroxyethyl)- dl -aspartamide (PHEA) and its pegylated derivative (PHEA-PEG2000) with poly(lactic acid) (PLA). To obtain nanosized particles, the high pressure homogenization (HPH)—solvent evaporation method was followed by using an organic phase containing both PHEA-PLA and PHEA-PEG2000-PLA (at a weight ratio equal to 1:…
In Vitro Evaluation of Poly(lactide-co-glycolide) In Situ Forming Gels for Bedaquiline Fumarate Salt and Pharmacokinetics Following Subcutaneous Inje…
2021
This study evaluated in vitro and in vivo drug release of bedaquiline from in situ forming gels (ISGs) containing 200 mg eq./g bedaquiline fumarate salt prepared with four different grades of poly(d,l-lactide) (PDLLA) or poly(d,l-lactide-co-glycolide) (PLGA) with a lactide/glycolide ratio of 50/50 or 75/25 and acid (A) or ester (E) end-capping in N-methyl-2-pyrrolidone at a polymer/solvent ratio of 20/80% (w/w). Mean in vitro drug release in 0.05 M phosphate buffer pH 7.4 with 1% (w/v) sodium lauryl sulphate was 37.3, 47.1, 53.3, and 62.3% within 28 days for ISGs containing PLGA5050A, PDLLA, PLGA7525A, and PLGA7525E, respectively. The data suggested that drug release was primarily controlle…
Lifestyle and Empowerment Techniques in Survivorship of Gynaecologic Oncology (LETSGO study): A study protocol for a multicentre longitudinal interve…
2021
IntroductionThe number of gynaecological cancer survivors is increasing and there is a need for a more sustainable model of follow-up care. Today’s follow-up model is time-consuming and patients have reported unmet needs regarding information about their cancer and strategies for managing the consequences of treatment. The main aim of this study is to assess health-related empowerment—in terms of patient education, psychosocial support, and promotion of physical activity—in a new follow-up model by comparing it to standard follow-up in a quasi-randomised study involving intervention hospitals and control hospitals.Methods and analysisAt the intervention hospitals, patients will be stratifie…
Seguridad del paciente en Radioterapia Intraoperatoria: impacto de los elementos controlados por el Radiofísico
2015
Introducción: en la administración de la radioterapia intervienen profesionales y equipos de tratamiento, por lo que existe el riesgo de error y se precisa que dicho equipamiento funcione conforme a lo esperado. A los radiofísicos les corresponde participar en las actividades de garantía o aseguramiento de la calidad, incluyendo el control de calidad de los equipos, y en la evaluación de los riesgos asociados. La radioterapia intraoperatoria (RIO) es una técnica radioterápica de intensificación de dosis, altamente selectiva, dirigida a volúmenes anatómicos restringidos durante el tratamiento quirúrgico oncológico, basada en la administración de una dosis absorbida alta por medio de un haz d…
FRI0030 Anti-TNF-α Antibody Targeted To Inflamed Synovial Tissue for The Treatment of Rheumatoid Arthritis
2016
Background TNF-α neutralizing molecules represent one of the most efficient therapeutic approaches to control inflammation in rheumatoid arthritis (RA). The widespread distribution in the body induces the inhibition of TNF-α in all the tissues, requesting the use of high dose of this expensive drug. Another problem that has not yet been solved in the management of RA patients is how to reduce and possibly avoid the side effects, particularly the increased risk of common and opportunistic infections, which may be associated with long-term administration of these therapeutic drugs. Objectives The aim of the present investigation was to show that a recombinant protein obtained by fusing a syno…

Existe un vasto cuerpo de investigación que evalúa los efectos de las intervenciones psicosociales sobre la adaptación psicológica durante el tratamiento del cáncer (Antoni, 2013; Guo et al., 2013; Stanton, 2006; Stanton, Luecken, MacKinnon y Thompson, 2013). En entornos oncológicos, las intervenciones basadas en Mindfulness han demostrado su eficacia para promover el bienestar y los dominios de calidad de vida (Sinatra y Black, 2018; Zainal, Booth y Huppert, 2013), estrategias de afrontamiento constructivas frente al estrés psicosocial relacionado con la enfermedad, aliviando la ansiedad, el estrés, la fatiga, el estado de ánimo general, la alteración del sueño (Carlson et al., 2003; Carls…
Virtual Reality, Augmented Reality, and In Vivo Exposure Therapy: A Preliminary Comparison of Treatment Efficacy in Small Animal Phobia
2018
This study aggregated data from three randomized control trials to explore the differential efficacy of three forms of exposure therapy, namely, in vivo (iVET), virtual reality (VRET), and augmented reality (ARET), in the treatment of small animal phobia. Additionally, baseline patient characteristics were used to detect subgroups of patients who showed a differential response to certain treatment modalities. Primary measures were distance covered, anxiety during the behavioral avoidance test (BAT), and overall fear of small animals. A repeated-measures analysis of variance was used to explore the overall treatment effect across the exposure modalities. A cluster analysis and an analysis of…
