Cytotoxicity and concentration of silver ions released from dressings in the treatment of infected wounds: a systematic review.

Introduction: Silver-releasing dressings are used in the treatment of infected wounds. Despite their widespread use, neither the amount of silver released nor the potential in vivo toxicity is known. The aim of this study was to evaluate the cytotoxic effects and the amount of silver released from commercially available dressings with infected wounds. Methods: The review was conducted according to the PRISMA statement. The Web of Science, PubMed, Embase, Scopus, and CINAHL databases were searched for studies from 2002 through December 2022. The criteria were as follows: population (human patients with infected wounds); intervention (commercial dressings with clinical silver authorized for use in humans); and outcomes (concentrations of silver ions released into tissues and plasma). Any study based on silver-free dressings, experimental dressings, or dressings not for clinical use in humans should be excluded. According to the type of study, systematic reviews, experimental, quasi-experimental, and observational studies in English, Spanish, or Portuguese were considered. The quality of the selected studies was assessed using the JBI critical appraisal tools. Studies that assessed at least 65% of the included items were included. Data were extracted independently by two reviewers. Results: 740 articles were found and five were finally selected (all of them quasi-experimental). Heterogeneity was found in terms of study design, application of silver dressings, and methods of assessment, which limited the comparability between studies. Conclusion: In vivo comparative studies of clinical dressings for control of infection lack a standardized methodology that allows observation of all the variables of silver performance at local and systemic levels, as well as evaluation of its cytotoxicity. It cannot be concluded whether the assessed concentrations of released silver in commercial dressings for the topical treatment of infected wounds are cytotoxic to skin cells.

Consensus document for lipid profile testing and reporting in Spanish clinical laboratories: what parameters should a basic lipid profile include?

Cardiovascular diseases (CVD) continue to be the main cause of death in our country. Adequate control of lipid metabolism disorders is a key challenge in cardiovascular prevention that is far from being achieved in real clinical practice. There is a great heterogeneity in the reports of lipid metabolism from Spanish clinical laboratories, which may contribute to its poor control. For this reason, a working group of the main scientific societies involved in the care of patients at vascular risk, has prepared this document with a consensus proposal on the determination of the basic lipid profile in cardiovascular prevention, recommendations for its realization and unification of criteria to incorporate the lipid control goals appropriate to the vascular risk of the patients in the laboratory reports.

Family Planning in Fertile-Age Patients With Multiple Sclerosis (MS) (ConPlanEM Study): Delphi Consensus Statements.

Family planning is essential for establishing Multiple Sclerosis (MS) prognosis, treatment decision, and disease monitoring. We aimed to generate an expert consensus addressing recommendations for family planning in MS patients of childbearing age. Initially, a committee comprising seven neurologists, experts in the MS field, identified the topics to be addressed. Then, the committee elaborated on different evidence-based preliminary statements. Next, using the Delphi methodology, a panel of neurologists manifested their level of agreement on the different statements using a Likert-type scale. Consensus was reached when ⩾70% of respondents expressed an agreement or disagreement using a five-point scale. Consensus was achieved on 47 out of 63 recommendations after three rounds of evaluations. The panel considered it essential to address family planning in all patients of childbearing age. There was also consensus that treatment should not be delayed due to the patient's desire for pregnancy. Additionally, in highly active patients, planning the pregnancy in the medium to long term using depletory drugs such as cladribine or alemtuzumab might represent a useful strategy. However, risks of adverse effects on the fetus due to drug-associated secondary autoimmunity should be addressed when alemtuzumab is considered. Moreover, the maintenance of natalizumab during pregnancy in very active patients reached expert consensus. Also, the panel supported the use of certain disease-modifying treatment (DMT) during lactation in selected cases. Our results identified specific areas of pregnancy planning in MS patients, where different treatment strategies might be considered to facilitate a safe and successful pregnancy while maintaining clinical and radiological stability.

Dietary Supplementation with Yerba Mate (Ilex paraguariensis) Infusion Increases IRS-1 and PI3K mRNA Levels and Enhances Insulin Sensitivity and Secretion in Rat Pancreatic Islets.

"Yerba mate" (YM), an aqueous extract of Ilex paraguariensis, has antioxidant, diuretic, cardio-protective and hypoglycaemic properties. Since its effect on the pancreatic islets remains unclear, we evaluated insulin sensitivity and glucose-stimulated insulin secretion (GSIS) in rats consuming YM or tap water (C) for 21 days. Glucose tolerance, glycemia, triglyceridemia, insulinemia, TBARS and FRAP serum levels were evaluated. GSIS and mRNA levels of insulin signaling pathway and inflammatory markers were measured in isolated pancreatic islets from both groups. In C rats, islets were incubated with YM extract or its phenolic components to measure GSIS. YM improved glucose tolerance, enhanced GSIS, increased FRAP plasma levels and islet mRNA levels of IRS-1 and PI3K (p110), and decreased TBARS plasma levels and islet gene expression of TNF-α and PAI-1. Islets from C rats incubated with 100 µg/mL dry YM extract, 1 µM chlorogenic acid, 0.1 and 1 µM rutin, 1 µM caffeic acid or 1 µM quercetin showed an increase in GSIS. Our results suggest that YM enhances glucose tolerance because of its positive effects on GSIS, oxidative stress rate and insulin sensitivity in rat islets, suggesting that long-term dietary supplementation with YM may improve glucose homeostasis in pre-diabetes or type 2 diabetes.

Barreras y actitudes para prevenir el efecto adverso de úlceras por presión en una unidad de traumatología / Barriers and attitudes to prevent the adverse effect of pressure ulcers in a trauma unit

Objetivo: Determinar el tipo de barreras y actitudes hacia la prevención de las úlceras por presión en una unidad hospitalaria de traumatología. Metodología: Estudio observacional descriptivo realizado en la Unidad de Traumatología General. Se aplicaron 3 cuestionarios: cuestionario de percepción de seguridad del paciente (PSP); cuestionario de actitudes hacia la prevención de las úlceras por presión (APuP) y cuestionario de barreras hacia la prevención de las úlceras por presión (BPUPP). Resultados: La muestra estuvo constituida por 35 profesionales (21 enfermeras y 14 auxiliares). Rango medio de edad, 31-50 años (57,2%); género predominante, mujer (94,3%); la media de experiencia laboral fue de < 5 años (71,4%), y como profesional titulado, < 10 años (34,3%). El 86,6% de los profesionales tenían formación en prevención de úlceras por presión. Se puntuó con un 7 a la unidad donde trabajaban en relación con la cultura de la seguridad y prevención de las úlceras por presión como evento adverso. Las enfermeras identificaron hasta 16 barreras y las auxiliares 18, de ellas 14 resultaron comunes. Conclusiones: Se observó una actitud positiva de los profesionales hacia las medidas de prevención, existiendo acuerdo en que las úlceras por presión son evitables y prevenibles. Sin embargo, prevalecen algunas barreras relacionadas con factores de tipo organizacional (excesiva rotación de personal), déficit de conocimientos (“siempre se ha hecho así”) o insuficiente colaboración y comunicación entre niveles asistenciales, resultados estos que concuerdan con lo publicado en la literatura y que urge buscarles solución (AU)

Objective: To determine the type of barriers and attitudes towards the prevention of pressure ulcers in a traumatology hospital unit. Methodology: Descriptive observational study conducted in the General Traumatology Unit. Three questionnaires were applied: Patient Perception of Safety Questionnaire (PSP); Attitudes towards PPU Prevention Questionnaire (APuP) and Barriers to PPU Prevention Questionnaire (BPUPP). Results: The sample consisted of 35 professionals (21 nurses and 14 assistants). Mean age range, 31-50 years (57.2%); predominantly female gender (94.3%), mean work experience was < 5 years (71.4%), and as a qualified professional < 10 years (34.3%). A total of 86.6% of the professionals were trained in PU prevention. The unit where they worked was scored with a seven in relation to the culture of safety and prevention of PUs as an adverse event. Nurses identified up to 16 barriers and assistants 18, of which 14 were common. Conclusions: A positive attitude of the professionals towards prevention measures was observed, with agreement that PUs are avoidable and preventable. However, some barriers related to organizational factors prevail (excessive staff turnover), knowledge deficit (“it has always been done this way”) or insufficient collaboration and communication between care levels, results that agree with those published in the literature and that it is urgent to seek solution (AU)

In vitro effects of European and Latin-American medicinal plants in CYP3A4 gene expression, glutathione levels, and P-glycoprotein activity.

Many medicinal plants species from European -such as Artemisia absinthium, Equisetum arvense, Lamium album, Malva sylvestris, Morus nigra, Passiflora incarnata, Frangula purshiana, and Salix alba- as well as Latin American traditions -such as Libidibia ferrea, Bidens pilosa, Casearia sylvestris, Costus spicatus, Monteverdia ilicifolia, Persea americana, Schinus terebinthifolia, Solidago chilensis, Syzygium cumini, Handroanthus impetiginosus, and Vernonanthura phosphorica- are shortlisted by the Brazilian National Health System for future clinical use. However, they lack many data on their action upon some key ADME targets. In this study, we assess non-toxic concentrations (up to100 µg/ml) of their infusions for in vitro ability to modulate CYP3A4 mRNA gene expression and intracellular glutathione levels in HepG2 cells, as well as P-glycoprotein (P-gp) activity in vincristine-resistant Caco-2 cells (Caco-2 VCR). We further investigated the activation of human pregnane X receptor (hPXR) in transiently co-transfected HeLa cells and the inhibition of Gamma-glutamyl transferase (GGT) in HepG2 cells. Our results demonstrate L. ferrea, C. sylvestris , M. ilicifolia, P. americana, S. terebinthifolia, S. cumini, V. phosphorica, E. arvense, P. incarnata, F. purshiana, and S. alba can significantly increase CYP3A4 mRNA gene expression in HepG2 cells. Only F. purshiana shown to do so likely via hPXR activation. P-gp activity was affected by L. ferrea, F. purshiana, S. terebinthifolia, and S. cumini. Total intracellular glutathione levels were significantly depleted by exposure to all extracts except S. alba and S. cumini This was accompanied by a lower GGT activity in the case of C. spicatus, P. americana, S. alba, and S. terebinthifolia, whilst L. ferrea, P. incarnata and F. purshiana increased it. Surprisingly, S. cumini aqueous extract drastically decreased GGT activity (-48%, p < 0.01). In conclusion, this preclinical study shows that the administration of some of these herbal medicines causes in vitro disturbances to key drug metabolism mechanisms. We recommend active pharmacovigilance for Libidibia ferrea (Mart.) L. P. Queiroz, Frangula purshiana Cooper, Schinus terebinthifolia Raddi, and Salix alba L. which were able to alter all targets in our preclinical study.

The Broad Concept of "Spasticity-Plus Syndrome" in Multiple Sclerosis: A Possible New Concept in the Management of Multiple Sclerosis Symptoms.

Multiple sclerosis (MS) pathology progressively affects multiple central nervous system (CNS) areas. Due to this fact, MS produces a wide array of symptoms. Symptomatic therapy of one MS symptom can cause or worsen other unwanted symptoms (anticholinergics used for bladder dysfunction produce impairment of cognition, many MS drugs produce erectile dysfunction, etc.). Appropriate symptomatic therapy is an unmet need. Several important functions/symptoms (muscle tone, sleep, bladder, pain) are mediated, in great part, in the brainstem. Cannabinoid receptors are distributed throughout the CNS irregularly: There is an accumulation of CB1 and CB2 receptors in the brainstem. Nabiximols (a combination of THC and CBD oromucosal spray) interact with both CB1 and CB2 receptors. In several clinical trials with Nabiximols for MS spasticity, the investigators report improvement not only in spasticity itself, but also in several functions/symptoms mentioned before (spasms, cramps, pain, gait, sleep, bladder function, fatigue, and possibly tremor). We can conceptualize and, therefore, hypothesize, through this indirect information, that it could be considered the existence of a broad "Spasticity-Plus Syndrome" that involves, a cluster of symptoms apart from spasticity itself, the rest of the mentioned functions/symptoms, probably because they are interlinked after the increase of muscle tone and mediated, at least in part, in the same or close areas of the brainstem. If this holds true, there exists the possibility to treat several spasticity-related symptoms induced by MS pathology with a single therapy, which would permit to avoid the unnecessary adverse effects produced by polytherapy. This would result in an important advance in the symptomatic management of MS.

La revisión sistemática: pluralidad de enfoques y metodologías / The systematic review: Plurality of approaches and methodologies

Una revisión sistemática se considera un tipo «especial» de artículo o documento científico que, sin llegar a ser original, resume el estado actual de la investigación sobre un tema en particular, mediante un proceso sistemático riguroso y reproducible. Surgió con el fin de ofrecer una visión y comprensión más profunda de un fenómeno específico de la realidad, tomando como base los resultados de otras investigaciones para consolidar el conocimiento existente e identificar problemas no resueltos. Esto facilitaría la toma de decisiones según la evidencia. Sin embargo, bajo el término genérico «revisión sistemática» se engloba muchos sinónimos que, por desconocimiento o mal uso, pueden confundirse. Este artículo explora cuáles son las diferentes tipologías de revisiones sistemáticas que podemos encontrar publicadas, en función de la organización de su enfoque y la metodología de síntesis del conocimiento empleada

A systematic review is considered a "special" type of scientific article that, without being original, summarizes the current state of research on a particular topic, through a rigorous and reproducible systematic process. It emerged in order to offer a deeper insight and to understand a specific phenomenon of reality, based on the results of other research to consolidate existing knowledge and identify unresolved problems. This could facilitate decision-making according to the evidence. However, many synonyms are included under the generic term "review" that, through ignorance or misuse, can be disconcerting. This article explores the different types of published systematic reviews that we can find published, depending on the organization of their approach and the knowledge synthesis methodology used

Calidad de las guías de práctica clínica sobre úlceras venosas de la extremidad inferior / Quality of clinical practice guidelines of lower extremity venous ulcers

La variabilidad clínica y la incertidumbre profesional en la prevención y tratamiento de las úlceras venosas de la extremidad inferior (UV) traen, como principal consecuencia, el hecho de que los pacientes puedan verse sometidos a pruebas diagnósticas y terapéuticas, a veces de dudosa utilidad, o incluso que estas puedan resultar nocivas para la salud del paciente o que, en otras ocasiones, puedan llegar a omitirse determinados procedimientos o procesos que sí podrían resultar adecuados a la situación y necesidades del paciente. Es por ello que surgen una serie de documentos específicos denominados guías de práctica clínica para el abordaje de las UV (GPC-UV), con la finalidad de mejorar la efectividad y la calidad de los cuidados, disminuir la variabilidad injustificada y establecer criterios homogéneos para su manejo. Sin embargo, la literatura recoge que no todas las GPC tienen el mismo criterio metodológico y de elaboración de la evidencia, por lo que muchas de ellas son de escasa calidad científica y rigor editorial. Esto implica que las GPC deben ser revisadas y actualizadas periódicamente en función de la evidencia más actual, y su calidad contrastada con instrumentos validados como el AGREE-II. Tras un análisis de la calidad de 6 GPC-UV disponibles en la actualidad, se ha podido identificar qué guías son recomendables para su implementación en la práctica asistencial y cuáles deberían modificarse para mejorar su aplicabilidad y desarrollo de las evidencias (AU)

The clinical variability and professional uncertainty in the prevention and treatment of lower extremity venous ulcers (VU) has as a main consequence, the fact that patients can be subjected to diagnostic and therapeutic tests, sometimes of dubious utility, these may even be harmful to the health of the patient and that, at other times, certain procedures or processes that may be appropriate to the patient's situation and needs may be omitted. It is for this reason that a series of specific documents called clinical practice guidelines for the approach of VU (CPG-VU) have been created, with the aim of improving the effectiveness and quality of care, reducing unjustified variability and establishing homogeneous criteria for its handling. Nevertheless, the literature shows that not all CPGs have the same methodological and evidence-drawing criteria. Many of them are of poor scientific quality and editorial rigor. This implies that CPGs should be periodically reviewed and updated based on the most current evidence and their quality contrasted with validated instruments such as AGREE-II. After an analysis of the quality of six CPG-VU available today, it has been possible to identify what guidelines are recommended for its implementation in the practice of care, which should be modified to improve their applicability and development of the evidence (AU)

Antecedentes de la terapia compresiva: el ‘método Baynton’ para el tratamiento de úlceras de la pierna / History of the compressive therapy: the ‘Baynton Method’ for the treatment of ulcers of the leg

El método Baynton o "cura Baynton" fue una técnica terapéutica de finales siglo XVIII que revolucionó el tratamiento conservador que hasta la fecha se aplicaba a la curación de las úlceras de la pierna. A través de la aplicación de un emplaste, un vendaje compresivo elástico en espiral y la movilización temprana de la extremidad, se lograron asentar las bases empíricas de lo que se conoce como "terapia de compresión". Se evidenció cómo la compresión mejoraba el edema, favorecía el ambiente húmedo logrando un efecto bacteriostático y cicatrizante sobre las úlceras tórpidas de la extremidad inferior, convirtiéndose en uno de avances médicos y de salud pública más importantes e innovadores de su época. Esta investigación representa uno de los escasos documentos que nos describen cómo fue evolucionando el conocimiento de la terapia de compresión para el tratamiento de úlceras crónicas de la extremidad inferior

The Baynton method or "Baynton cure" was a therapeutic technique of the late eighteenth century that revolutionized the conservative treatment that until the date applied to the healing of ulcers of the leg. Through the application of a dressing of diachylon, a compressive bandage pad spiral and the early mobilization of the extremity, it managed to settle the empirical bases of what is known as compression therapy. It is evident as the compression improved the edema, favored the humid environment and achieved a bacteriostatic effect and healing on the chronic ulcers of the lower extremity, becoming one of medical advances and most important public health and innovative of his time. This research represents one of the few documents that describe us as was evolving knowledge of the compression therapy for the treatment of chronic ulcers of the lower extremity

Implementar evidencias e investigar en implementación: dos realidades diferentes y prioritarias / Implementing evidence and implementation research: two different and prime realities

La investigación científica puede contribuir a hacer más eficientes los cuidados de salud, a mejorar la calidad asistencial y la seguridad de las personas. Para que así suceda, el conocimiento generado debe transferirse a la práctica. Se conoce como implementación la introducción de un cambio o innovación en la práctica diaria, lo que exige una comunicación efectiva y la eliminación de barreras que dificulten este proceso. En el ámbito de enfermería, cada vez es más frecuente la realización de experiencias de implementación de buenas prácticas. La dificultad para identificar los factores que permiten conocer el éxito o fracaso de la implementación ha dado lugar al incremento de estudios encaminados a construir un cuerpo de conocimientos diferenciados, conocido como ciencia de la implementación o investigación en implementación. La investigación en implementación es el estudio científico cuyo objetivo es la adopción e incorporación sistemática de los resultados de investigación en la práctica clínica para mejorar la calidad y eficacia de los servicios de salud. El fin que persigue la investigación en implementación es mejorar la salud de la población mediante la aplicación equitativa y eficaz del conocimiento científico rigurosamente evaluado, lo que implica la captación de aquellas evidencias que hayan producido un impacto positivo en la salud de la comunidad. En este texto se exponen las particularidades de la investigación enfermera en implementación, realizándose una síntesis de los diferentes métodos, teorías, marcos determinantes y estrategias de implementación, junto con la terminología propuesta para una mayor claridad conceptual

Scientific research can contribute to more efficient health care, enhance care quality and safety of persons. In order for this to happen, the knowledge gained must be put into practice. Implementation is known as the introduction of a change or innovation to daily practice, which requires effective communication and the elimination of barriers that hinder this process. Best practice implementation experiences are being used increasingly in the field of nursing. The difficulty in identifying the factors that indicate the success or failure of implementation has led to increased studies to build a body of differentiated knowledge, recognized as implementation science or implementation research. Implementation research is the scientific study whose objective is the adoption and systematic incorporation of research findings into clinical practice to improve the quality and efficiency of health services. The purpose of implementation research is to improve the health of the population through equitable and effective implementation of rigorously evaluated scientific knowledge, which involves gathering the evidence that has a positive impact on the health of the community. In this text, we set out the characteristics of nursing implementation research, providing a synthesis of different methods, theories, key frameworks and implementation strategies, along with the terminology proposed for greater conceptual clarity
