Effect of pores on the mechanical and durability properties on high strength recycled fine aggregate mortar

[EN] Larger consumption of natural fine aggregates (NFA) leads to an increase in cost, energy, and negative environmental impact. On the contrary, the larger production of construction waste results in the generation of recycled fine aggregate (RFA), which requires safe disposal. The aim of study, is to the hunt for such alternatives, compares the mortar mechanical and durability properties with and without RFA. High strength mortar specimens were produced with mix proportion as 1:3 using RFA as partial replacement for NFA as 0%, 25%, 50% and 100%. The mechanical and durability performance of all specimens was assessed in the terms of compressive strength, flexural strength, water absorption and mercury intrusion porosimetry. Mechanical performance is confirmed by microscopic studies. The main results display that the mortar with 25% of RFA, performed better, which are related to pore structures and their distribution. It is noted that the, pores also increase with the increase in RFA content. The effect of pores on the strength and their relationships are assessed.SIAuthor wish to thank for the supports and guidance given by faculties from University of Leon, Leon, Spain and Coimbatore Institute of Technology, Coimbatore, Indi

Application of molecular topology to the prediction of inhibition of Trypanosoma cruzi Hexokinase by bisphosphonates

Se ha desarrollado un modelo topológico-matemático para la búsqueda de nuevos derivados bisfosfonatos activos frente a la hexokinasa de Trypanosoma cruzi. Utilizando el análisis lineal discriminante se ha seleccionado una función con cuatro variables capaz de predecir adecuadamente la CI50 para cada compuesto de las series de entrenamiento y test. El modelo propuesto se ha aplicado a una librería molecular y se han propuesto nuevas estructuras potencialmente activas frente a T. cruzi.A topological-mathematical model has been arranged to search for new derivatives of bisphosphonate compounds acting as inhibitors against Trypanosoma cruzi hexokinase. By using linear discriminant analysis, a four-variable function was achieved allowing an accurate prediction of the IC50 for each compound of the training and test series. After carrying out a virtual screening based upon such a model, new structures potentially actives against T. cruzi are proposed.Este trabajo ha sido posible gracias al Fondo de Investigación Sanitaria, Ministerio de Sanidad, España (proyecto SAF2005-PIO52128) y al Máster Internacional en Enfermedades Parasitarias Tropicales, Universidad de Valencia

The short and long-term effects of aerobic, strength, or mixed exercise programs on schizophrenia symptomatology

The purpose of this study was to compare the effects of three different physical exercise programs on the symptomatology, body composition, physical activity, physical fitness, and quality of life of individuals with schizophrenia. A total of 432 patients were assessed for eligibility and 86 were randomized into the aerobic (n = 28), strength (n = 29) or mixed (n = 29) groups. Positive, negative, and general symptoms of psychosis, body mass index (BMI), physical activity (IPAQ-SF), physical fitness (6-min walk test [6MWT] and hand-grip strength [HGS]), and quality of life (WHOQUOL-BREF) were assessed at baseline, post-intervention (16 weeks), and at 10-months. Our results at 16 weeks showed significant improvements in all three groups in the negative, general, and total symptoms with moderate to large effect sizes (P < 0.01, ¿p2 > 0.11), no change in the BMI, 6MWT or IPAQ-SF, and a significant improvement in the HGS test in the strength and mixed groups (P = 0.05, ¿p2 > 0.08). Nonetheless, all the improvements had disappeared at 10 months. We concluded that 3 weekly sessions of a moderate to vigorous progressive exercise program for 16 weeks improved the symptomatology of individuals with schizophrenia in all three groups, with no differences between them. However, the effects had declined to baseline levels by the 10-month follow-up, suggesting that exercise interventions should be maintained over time. © 2021, The Author(s)

Registration system of professional performances defendants in Community Pharmacy.

INTRODUCCION El diseño de una herramienta o sistema de registro de todas las actuaciones profesionales (AP) que demanda el usuario en la farmacia comunitaria, en el mostrador, donde el farmacéutico realiza la mayor parte de su labor, es imprescindible para entender la barrera de falta de “tiempo” para implantar o desarrollar servicios cognitivos en la farmacia comunitaria. MATERIAL Y METODO El equipo investigador del estudio diseñó la herramienta de registro utilizando como soporte informático el sistema de gestión disponible en las farmacias participantes en el estudio (FARMATCR). Después de un pilotaje de 15 días y de los ajustes necesarios se creó la herramienta definitiva. Los requisitos básicos que se persiguieron para el diseño de la herramienta, fueron: Registrar todas las AP demandadas en el mostrador de la farmacia comunitaria. Recopilar la máxima información para cada una de las AP. Mantener la agilidad en la resolución de las mismas. Se decide hacer un control de calidad de la herramienta para saber si satisface las necesidades para lo que se ha diseñado. RESULTADO: herramienta FINAL La herramienta consiste en la introducción en el sistema informático (FARMATCR,) de una serie de códigos de trabajo nuevos (artículos, aportaciones y desplegables). DISCUSION Es difícil encontrar un equilibrio entre agilidad y rigor del registro. La herramienta es capaz de cuantificar las AP que se realizan en el mostrador, pero con limitaciones.INTRODUCTION Designing a tool or registration system for all professional activities requested by all user over the counter in the community pharmacy, where the pharmacist conducts most of its work, is essential to enable the understanding of the barrier of “lack of time” in order to establish or develop cognitive services in the community pharmacy . METHOD The research team working on this survey, designed the registered tool using the management system available in all pharmacies participants in the survey, as a computerized record (FARMATICR) The ultimate tool was created after 15 days of pile work and needed adjustments. The basic requirements pursued for the design of the tool were: The recording of all professional activities requested at the counter in pharmacies. The compiling of all information for each of the professional activities To maintain the flexibility in the resolutions of these. It was decided to have constant feedback of the quality of the tool to see if it met the requirements for its designed purpose. RESULTS The tool is the introduction into the computer system (FARMATICR,) of a series of new labor codes (articles, transfers and leaflets). DISCUSSION.

Actuaciones profesionales realizadas en la farmacia comunitaria

Objetivo: Describir todas las actuaciones profesionales (AP) que se llevan a cabo como respuesta a las demandas realizadas por los usuarios en la farmacia comunitaria (FC). Material y métodos: Estudio observacional, descriptivo y transversal, realizado durante 6 meses en dos farmacias comunitarias de Denia (Alicante). La población de estudio fueron todas las demandas de servicio que realizaron los usuarios de ambas farmacias. La variable de estudio fue la AP, es decir, cada uno de los servicios demandados por el usuario en la FC: dispensación, indicación, automedicación, consultas y ventas, clasificándose cada uno en sus resoluciones e incidencias. Resultados: En el estudio se realizaron 30.617 AP, correspondiendo un 42% a la dispensación con receta, y se registró casi un 23% de incidencias. Las indicaciones farmacéuticas supusieron un 9% del total, resolviéndose en la mayoría de casos con la recomendación de un medicamento. Un 33% fueron demandas de automedicación, cursando con casi un 20% de incidencias. Un 7% fueron consultas y un 10% ventas de productos sanitarios. Conclusiones: Del total de AP realizadas, el 90% se consideran farmacéuticas. El 83% fueron dispensaciones de medicamentos, más de la mitad de éstas sin prescripción médica, lo que revela la importancia del asesoramiento farmacéutico en las dispensaciones sin receta. El hecho de que 9 de cada 10 incidencias que se producen en la dispensación con receta y en la automedicación sean por la falta de información del paciente nos pone en alerta sobre la necesidad de implementar medidas que mejoren esta carencia

Microbiota composition and intestinal integrity remain unaltered after the inclusion of hydrolysed Nannochloropsis gaditana in Sparus aurata diet

The use of lysed microalgae in the diet of carnivorous fish can increase the bioavailability of proteins and bioactive compounds, such as unsaturated fatty acids or vitamins in the digestive tract. These are essential molecules for the proper physiological development of fish in aquaculture. However, some antinutritional components and other undesirable molecules can be released from an excess of microalgae supplied, compromising the integrity of the intestine. The inclusion of small amounts of hydrolized microalgae in the fish diet can be a good strategy to avoid negative effects, improving the availability of beneficial compounds. Nannochloropsis gaditana is an interesting microalgae as it contains nutraceuticals. Previous studies reported beneficial effects after its inclusion in the diet of Sparus aurata, a widely cultured species in Europe and in all Mediterranean countries. However, administration of raw microalgae can produce intestinal inflammation, increased intestinal permeability, bacterial translocation and disturbance of digestion and absorption processes. The aim of this study was to evaluate changes in the intestinal microbiota and barrier stability of S. aurata fed with low inclusion (5%) hydrolysed N. gaditana. Intestinal microbiota was analyzed using Illumina MiSeq technology and libraries were constructed using variable regions V3-V4 of 16S rDNA molecules. Analysis were based in the identification, quantification and comparison of sequences. The predictive intestinal microbial functionality was analyzed with PICRUSt software. The results determined that the intestinal microbiota bacterial composition and the predictive intestinal microbiota functionality did not change statistically after the inclusion of N. gaditana on the diet. The study of gene expression showed that genes involved in intestinal permeability and integrity were not altered in fish treated with the experimental diet. The potential functionality and bacterial taxonomic composition of the intestinal microbiota, and the expression of integrity and permeability genes in the intestine of the carnivorous fish S. aurata were not affected by the inclusion of hydrolysed 5% N. gaditana microalgae

Predictive factors and early biomarkers of response in multiple sclerosis patients treated with natalizumab

There are an increasing number of treatments available for multiple sclerosis (MS). The early identification of optimal responders to individual treatments is important to achieve individualized therapy. With this aim, we performed a multicenter retrospective longitudinal study including 186 MS patients treated with natalizumab who were followed for 2 years. We analyzed the following variables at recruitment: sex, current age, age at disease onset, disease duration, EDSS, number of T2 and Gd + lesions, IgG and IgM oligoclonal bands, HLA class II (DR, DRB, DQA, DQB, and DRB1*15:01), IgG and IgM antibody titers against human herpesvirus 6 (HHV-6) and the antibody response to Epstein–Barr virus (EBV) through the measurement of the anti-EBNA-1 and anti-VCA IgG titers, in relation to clinical response (no relapses or disability progression), and to NEDA-3 (no evidence of disease activity in terms of clinical response and no changes in MRI scans either) after 2-years follow-up. Baseline EDSS score, baseline EBNA-1 IgG titers and percentage change of HHV6 IgG titers between baseline and 6 month visits were significantly different in clinical responders and in NEDA-3 status (all of them remained significant in the multivariate analysis). We identified three variables for the early identification of natalizumab optimal responders in a rapid and cost-effective approach

Determinants and Differences in Satisfaction with the Inhaler Among Patients with Asthma or COPD

Satisfaction with the inhaler is an important determinant of treatment adherence in patients with asthma and chronic obstructive pulmonary disease (COPD). However, few studies have compared these 2 groups to identify the factors associated with satisfaction with the inhaler. To assess and compare satisfaction with the inhaler in patients with asthma or COPD and to determine the variables associated with high inhaler satisfaction. A multicenter, cross-sectional study of 816 patients (406 with asthma and 410 with COPD) was conducted. Satisfaction was assessed with the Feeling of Satisfaction with Inhaler (FSI-10) questionnaire. All participants completed the Test of Adherence to Inhalers and either the Asthma Control Test (ACT) or the COPD Assessment Test (CAT). Overall, the asthma group was significantly more satisfied with the inhaler (mean [standard deviation] FSI-10 scores: 44.1 [6.5] vs 42.0 [7.7]; P <.001) and more satisfied on most (7 of 10; 70%) items. Patients with asthma were significantly more satisfied with the inhaler regardless of the adherence level or the type of nonadherence pattern. Younger age, good disease control (ACT ≥20 or CAT ≤10), previous inhaler training, and absence of unwitting nonadherence were all independently and significantly associated with high inhaler satisfaction. Age, disease control, and training in inhalation technique all play a more significant role than the specific diagnosis in explaining satisfaction with the device in patients with asthma and COPD. These findings underscore the need to provide better training and more active monitoring of the inhalation technique to improve patient satisfaction, treatment adherence, and clinical outcomes
