Formulative Study and Characterization of Novel Biomaterials Based on Chitosan/Hydrolyzed Collagen Films.

To date, the need for biomaterials capable of improving the treatment of chronic skin wounds remains a clinical challenge. The aim of the present work is to formulate and characterize chitosan (Cs)/hydrolyzed collagen (HC) films as potential biomaterials with improved mechanical and hydration performances compared to single component formulations. Films were made by the solvent casting method, with or without glycerin and/or PEG1500 as plasticizers, resulting in a total of eight formulations. All films were characterized by their physico-chemical characteristics and their mechanical and hydration features. A full factorial design was also used to statistically assess the effect of HC concentration, type and concentration of plasticizers and their possible interactions on mechanical and swelling behaviors. Solid state characterization confirmed the hybrid nature of the films, with suggested electrostatic interactions between Cs and HC. Mechanical and swelling properties, along with the analysis of the experimental design, allowed the identification of formulations containing high HC concentration (2% w/v) and glycerin or glycerin/PEG1500 as more suitable candidates for skin wound treatment. Finally, viability assay of immortalized human keratinocytes (HaCaT) showed no statistical differences in cell survival compared to the complete culture medium, suggesting their potential as a promising tool for biomedical applications.

Characterization and Molecular Modelling of Non-Antibiotic Nanohybrids for Wound Healing Purposes.

The healing process of chronic wounds continues to be a current clinical challenge, worsened by the risk of microbial infections and bacterial resistance to the most frequent antibiotics. In this work, non-antibiotic nanohybrids based on chlorhexidine dihydrochloride and clay minerals have been developed in order to design advanced therapeutic systems aimed to enhance wound healing in chronic lesions. To prepare the nanohybrids, two methodologies have been compared: the intercalation solution procedure and the spray-drying technique, the latter as a one-step process able to reduce preparation times. Nanohybrids were then fully studied by solid state characterization techniques. Computational calculations were also performed to assess the interactions between the drug and the clays at the molecular level. In vitro human fibroblast biocompatibility and antimicrobial activity against Staphylococcus aureus and Pseudomonas aeruginosa were assessed to check biocompatibility and potential microbicidal effects of the obtained nanomaterials. The results demonstrated the effective organic/inorganic character of the nanohybrids with homogeneous drug distribution into the clayey structures, which had been confirmed by classical mechanics calculations. Good biocompatibility and microbicidal effects were also observed, especially for the spray-dried nanohybrids. It was suggested that it could be due to a greater contact area with target cells and bacterial suspensions.

Self-Assembled Lanthanide Antenna Glutathione Sensor for the Study of Immune Cells.

The small molecule 8-methoxy-2-oxo-1,2,4,5-tetrahydrocyclopenta[de]quinoline-3-carboxylic acid (2b) behaves as a reactive non-fluorescent Michael acceptor, which after reaction with thiols becomes fluorescent, and an efficient Eu3+ antenna, after self-assembling with this cation in water. This behavior makes 2b a highly selective GSH biosensor, which has demonstrated high potential for studies in murine and human cells of the immune system (CD4+ T, CD8+ T, and B cells) using flow cytometry. GSH can be monitored by the fluorescence of the product of addition to 2b (445 nm) or by the luminescence of Eu3+ (592 nm). 2b was able to capture baseline differences in GSH intracellular levels among murine and human CD4+ T, CD8+ T, and B cells. We also successfully used 2b to monitor intracellular changes in GSH associated with the metabolic variations governing the induction of CD4+ naïve T cells into regulatory T cells (TREG).

Harmful Use of Alcohol as Predictor of Presex Drinking in Mexican Young College Women.

AIM: The aim of this study was to identify whether the harmful use of alcohol is associated with an increased probability of presex drinking in Mexican young women. METHOD: This was a study with a predictive design. Multiple logistic regressions were performed in a random sample of 304 young college women (between the ages of 18 and 24 years) from Guanajuato and Tamaulipas, Mexico. Participants completed a sociodemographic data survey and the Alcohol Use Disorders Identification Test questionnaire. RESULTS: Women with a pattern of harmful use of alcohol were more likely to report drinking before sex (adjusted odds ratio = 4.679, 95% confidence interval [1.619, 13.520], McFadden's pseudo R2 = 25.5%). Further analyses revealed that presex drinking by partners was an even stronger predictor of alcohol use before sexual intercourse in women (adjusted odds ratio = 12.749, 95% confidence interval [4.714, 34.483], McFadden's pseudo R2 = 34.7%). CONCLUSIONS: The findings demand additional nursing studies to corroborate-and to better understand-the relationship between harmful use of alcohol in Mexican women, their partners' drinking behavior, and unhealthy behaviors like drinking before sexual intercourse.

Desarrollo sostenible: Impacto ambiental y retos de los hospitales ante la Covid-19 / Sustainable development: Environmental impact and challenges for hospitals in the face of Covid-19

Señor editor: Los gobiernos a nivel mundial en los últimos 50 años han generado conjuntamente diversas agendas, compromisos y planes que abordan las necesidades derivadas de las interacciones sociales, económicas y ambientales; tal es el caso de Alma Ata, Agenda 21, y los Objetivos de Desarrollo Sostenible (ODS); entre otras, lo que conlleva a establecer responsabilidades políticas en salud relacionadas con el desarrollo sostenible en cada continente, región y país. Sin embargo, la actual crisis mundial generada por el Coronavirus (COVID-19) ha dificultado la continuidad de estos compromisos, priorizando el combate a este terrible mal y que hasta la fecha no existe una aparente solución.

Mr. Editor: Governments worldwide in the last 50 years have jointly generated various agendas, commitments and plans that address the needs arising from social, economic and environmental interactions; such is the case of Alma Ata, Agenda 21, and the Sustainable Development Goals (SDGs); among others, which leads to establish political responsibilities in health related to sustainable development in each continent, region and country. However, the current global crisis generated by the Coronavirus (COVID-19) has hindered the continuity of these commitments, prioritizing the fight against this terrible disease and to date there is no apparent solution.

Synthesis, Photophysics, and Solvatochromic Studies of an Aggregated-Induced-Emission Luminogen Useful in Bioimaging.

Biological samples are a complex and heterogeneous matrix where different macromolecules with different physicochemical parameters cohabit in reduced spaces. The introduction of fluorophores into these samples, such as in the interior of cells, can produce changes in the fluorescence emission properties of these dyes, caused by the specific physicochemical properties of cells. This effect can be especially intense with solvatofluorochromic dyes, where changes in the polarity environment surrounding the dye can drastically change the fluorescence emission. In this article, we studied the photophysical behavior of a new dye and confirmed the aggregation-induced emission (AIE) phenomenon with different approaches, such as by using different solvent proportions, increasing the viscosity, forming micelles, and adding bovine serum albumin (BSA), through analysis of the absorption and steady-state and time-resolved fluorescence. Our results show the preferences of the dye for nonpolar media, exhibiting AIE under specific conditions through immobilization. Additionally, this approach offers the possibility of easily determining the critical micelle concentration (CMC). Finally, we studied the rate of spontaneous incorporation of the dye into cells by fluorescence lifetime imaging and observed the intracellular pattern produced by the AIE. Interestingly, different intracellular compartments present strong differences in fluorescence intensity and fluorescence lifetime. We used this difference to isolate different intracellular regions to selectively study these regions. Interestingly, the fluorescence lifetime shows a strong difference in different intracellular compartments, facilitating selective isolation for a detailed study of specific organelles.

Revisión del efecto de la incertidumbre en personas adultas con diabetes mellitus tipo 2 / Review of the effect of uncertainty in adults with type 2 diabetes mellitus

Introducción: cuando a una persona se le diagnostica con diabetes mellitus tipo 2 (DM2), dicha noticia le suele representar un conjunto de emociones, como estrés, ansiedad e incertidumbre frente a la enfermedad, lo que la sitúa en la imposibilidad para predecir los resultados. Objetivo: realizar una revisión del estado del arte del periodo 2011 a 2016 sobre los efectos de la incertidumbre en las personas adultas con DM2. Métodos: la revisión se efectuó con base en las etapas propuestas por Dal Sasso-Mendes, en las bases de datos EBSCO, PubMed, SciELO, CONRICyT, ScienceDirect y Scopus. Se emplearon dos descriptores en Ciencias de la Salud (DeCS) en los idiomas inglés, español y portugués: Diabetes Mellitus Type 2, Diabetes Mellitus Tipo 2 y Diabetes Mellitus Tipo 2, así como Uncertainty, Incertidumbre e Incerteza. Se identificaron 2721 artículos, de los cuales se seleccionaron 23 artículos que cumplieron los criterios de inclusión. Resultados: de los diferentes componentes de la incertidumbre y DM2, se conformaron cuatro componentes: teórico, apoyo social, respuestas emocionales y diferencias en el tratamiento. Se identificó una relación de los componentes teórico y de apoyo social (21.7%) con la incertidumbre y con mayor énfasis el componente de diferencias en el tratamiento (43.5%). Conclusión: se identificó que el efecto de la incertidumbre de los pacientes ante la DM2 es una situación poco investigada, principalmente en lo que respecta a las respuestas emocionales.

Introduction: When a person is diagnosed with type 2 diabetes mellitus (T2DM), this news usually represents a set of emotions, such as stress, anxiety, and uncertainty about the disease. This puts the person in a difficult position, due to their inability to predict the results. Objective: To carry out a state-of-the-art review, from 2011 to 2016, on the effects of uncertainty in adults with T2DM. Methods: Based on the stages proposed by Dal Sasso-Mendes, the review was performed in the following databases: Ebsco, PubMed, SciELO, Conricyt, ScienceDirect, and Scopus. Two health sciences descriptors were used in English, Spanish and Portuguese: Diabetes Mellitus, Type 2, and Diabetes Mellitus Tipo 2 (for Spanish and Portuguese), as well as Uncertainty, Incertidumbre, and Incerteza. 2721 articles were identified, out of which 23 that met the selection criteria were selected. Results: From the different components of uncertainty and T2DM, four were formed: theoretical, social support, emotional responses, and differences in treatment. It was identified a relation between theoretical and social support components (21.7%) with uncertainty, with greater emphasis in the differences in treatment component (43.5%). Conclusion: It was identified that the effect of uncertainty on patients facing T2DM is a relatively unresearched situation, mainly concerning emotional responses.
