The incidence and prevalence of age-related neurodegenerative dementias have been increasing. There is no curative therapy and conventional drug treatment can cause problems for patients. Medicinal plants traditionally used for problems associated with ageing are emerging as a therapeutic resource. The main aim is to give a proposal for use and future research based on scientific knowledge and tradition. A literature search was conducted in several searchable databases. The keywords used were related to neurodegenerative dementias, ageing and medicinal plants. Boolean operators and filters were used to focus the search. As a result, there is current clinical and preclinical scientific information on 49 species used in traditional medicine for ageing-related problems, including neurodegenerative dementias. There are preclinical and clinical scientific evidences on their properties against protein aggregates in the central nervous system and their effects on neuroinflammation, apoptosis dysregulation, mitochondrial dysfunction, gabaergic, glutamatergic and dopaminergic systems alterations, monoamine oxidase alterations, serotonin depletion and oestrogenic protection. In conclusion, the potential therapeutic effect of the different medicinal plants depends on the type of neurodegenerative dementia and its stage of development, but more clinical and preclinical research is needed to find better, safer and more effective treatments.

Introducción: el cáncer de mama es la neoplasia maligna más frecuente entre las mujeres, y en España es la que produce mayor número de muertes al año. La detección precoz propicia tratamientos menos agresivos y mayores tasas de curación. El objetivo de este estudio es analizar los factores de riesgo de las mujeres que acudieron a las oficinas de farmacia participantes en el estudio: antecedentes familiares, edad y sexo, edad de concepción, enfermedad mamaria benigna, sobrepeso u obesidad, terapia hormonal (anticonceptivos orales o terapia hormonal sustitutiva), tabaco y alcohol. Material y métodos: En el estudio participaron cinco oficinas de farmacia de distintas provincias. Para el análisis de los factores de riesgo se entregó a las mujeres una breve encuesta que debían completar. Resultados y conclusiones: Tras analizar los factores de riesgo, se concluye que un 12% de las mujeres participantes tiene un riesgo elevado de padecer cáncer de mama. Desde la farmacia se puede informar a las mujeres sobre los factores de riesgo del cáncer de mama, con el fin de que apliquen las medidas necesarias para prevenir y/o detectar a tiempo esta enfermedad.

Introducción: La educación para la salud es una de las actividades que debe realizar el farmacéutico comunitario orientada hacia el paciente. Con el objetivo de conocer la influencia de la educación sanitaria en los pacientes, se realizó un estudio controlado en farmacias comunitarias de la provincia de Castellón. Material y métodos: En el estudio participaron catorce oficinas de farmacia (siete en el grupo control y siete en el grupo intervención). En todas ellas se realizó una encuesta inicial a los pacientes sobre educación para la salud. En las farmacias del grupo intervención se realizaron cinco campañas de educación sanitaria y al finalizar cada campaña los pacientes completaron una encuesta para valorar la educación sanitaria recibida. En las farmacias del grupo control se pasaron las encuestas a los pacientes pero no se realizaron las campañas de educación sanitaria. Resultados y discusión: Los pacientes están significativamente más satisfechos con la formación que reciben en las farmacias que realizan educación sanitaria. Además, se incrementa significativamente la percepción que tiene la población del farmacéutico en la oficina de farmacia como punto de referencia a la hora de ayudar a resolver sus problemas de salud. La educación sanitaria permite que los pacientes reciban formación completa acerca de temas de salud que les preocupan y les proporciona más capacidad para resolverlos por ellos mismos.

Leishmaniasis, African sleeping sickness and Chagas disease, caused by the kinetoplastid parasites Leishmania spp, Trypanosoma brucei and Trypanosoma cruzi, respectively, are among the most important parasitic diseases, affecting millions of people and considered to be within the most relevant group of neglected tropical diseases. The main alternative to control such parasitosis is chemotherapy. Nevertheless, the current chemotherapeutic treatments are far from being satisfactory. This review outlines the current understanding of different drugs against leishmaniasis, African sleeping sickness and Chagas disease, their mechanism of action and resistance. Recent approaches in the area of anti-leishmanial and trypanocidal therapies are also enumerated, new modulators from the mode of action, development of new formulations of old drugs, therapeutic switching and “in silico” drug design.

A series of compounds containing the nitrobenzene and sulfonamido moieties were synthesized and their leishmanicidal effect was assessed in vitro against Leishmania infantum promastigotes. Among the compounds evaluated, the p-nitrobenzenesulfonamides 4Aa and 4Ba, and the p-nitroaniline 5 showed significant activity with a good selectivity index. In a Balb/c mice model of L. Infantum, administration of compounds 4Aa, 4Ba or 5 (5 mg/kg/day for 10 days, injected ip route) led to a clear-cut parasite burden reduction (ca. 99%). In an attempt to elucidate their mechanism of action, the DNA interaction of 4Aa and 5 was investigated by means of viscosity studies, thermal denaturation and nuclease activity assay. Both compounds showed nuclease activity in the presence of copper salt. The results suggest that compounds 4Aa, 4Ba and 5 represent possible candidates for drug development in the therapeutic control of leishmaniasis.

Percutaneous transdermal absorption of esculetin (6,7-dihydroxycoumarin), an oxidative damage inhibitor, was evaluated by means of in vitro permeation studies in which vertical Franz-type diffusion cells and pig ear skin were employed. To determine the absorption of esculetin, we validated a simple, accurate, precise, and rapid HPLC-UV method. Additionally, the effects of several percutaneous enhancers were studied. Pretreatment of porcine skin was performed with ethanol (control vehicle), decenoic acid, oleic acid, R-(+)-limonene, and laurocapram (Azone®) (5% in ethanol, w/w, respectively). Pretreatment of skin with oleic acid or laurocapram led to statistically significant differences in the transdermal flux of esculetin with respect to controls. Of the two enhancers, laurocapram showed the greatest capacity to enhance the flux of esculetin across pig skin.

Vitiligo is a chronic disease of unknown etiology that causes progressive cutaneous depigmentation. Current pharmacological treatments have limited success and present significant risks. Many efforts have been made in recent years to explore new anti-vitiligo therapeutic strategies, including herbal-based therapies. The objective of the present review is to provide an updated overview on the most frequently used medicinal plants in the treatment of vitiligo. A bibliographical search was carried out in scientific databases Pubmed, Scifinder, Scopus, Google Scholar, and Medline up to October 2021 using the descriptors vitiligo, herbal, medicinal plants, and alternative therapies. In our search, the highest number of published studies comprise plants commonly used in traditional herbal medicine, highlighting the usefulness of ethnopharmacology in the discovery of new therapeutic agents. The review outlines current understanding and provides an insight into the role of psoralens and khellin (photosensitizing agents obtained from plants such as Cullen corylifolium or Ammi visnaga). The paper also describes other traditional herbs such as Ginkgo biloba, Phlebodium aureum, Piper nigrum, Picrorhiza kurroa, and Baccharoides anthelmintica that can likewise act as potential therapeutical agents. Based on our findings, photosensitizing agents in combination with phototherapy, the association of oral Phebodium aureum with phototherapies as well as oral G. biloba in monotherapy showed greater scientific evidence as therapeutic options. The research results emphasize that further investigation in this area is merited. More long-term follow up clinical trials and higher quality randomized trials are needed.

The retina may suffer neurodegenerative damages, as other tissues of the central nervous system do, and serious eye diseases may develop. One of them is age-related macular degeneration, which causes progressive loss of vision due to retina degeneration. Treatment of age-related macular degeneration focuses on antioxidant agents and anti-vascular endothelial growth factor compounds, among others, that prevent/ diminish oxidative stress and reduce neovascularisation respectively. The phytochemicals, medicinal plants and/or plant-diet supplements might be a useful adjunct in prevention or treatment of age-related macular degeneration owing to their antioxidant and anti-vascular endothelial growth factor properties. This review article presents the most investigated plants and natural products in relation to age-related macular degeneration, such as saffron, ginkgo, bilberry and blueberry, curcuma or turmeric, carotenoids, polyphenols, and vitamins C and E. This study provides up-to-date information on the effects, treatments, safety and efficiency of these phytotherapy products.

La clase invertida es un modelo pedagógico creado en 2012 por Jonathan Bergmann y Aaron Sams, profesores de Química en Woodland Park High School (Woodland Park Colorado). En este modelo, el profesor, en lugar de utilizar el tiempo de la clase para introducir nueva materia (vía lección magistral), previamente a que tenga lugar la clase proporciona a los alumnos, a través de la plataforma virtual, material docente (videos, artículos, podcast, etc.) para ayudarles a clarificar la materia objeto de estudio, de manera que puede utilizar el tiempo de la clase para realizar actividades docentes colaborativas. El material docente debe incluir las ideas principales de la unidad de estudio y puede ser creado por el profesor o descargado de internet. Esta actividad se ha desarrollado en el primer cuatrimestre del curso 2018-19 en las asignaturas Farmacología Clínica en el Grado de Farmacia y Farmacología del Grado en Medicina. Basándonos en los resultados obtenidos, la actividad ha resultado muy interesante para los estudiantes. La clase invertida les ha ayudado a clarificar conceptos y algunos estudiantes han considerado que tener conocimientos previos es importante para realizar la actividad, aunque no es esencial. / Flipped classroom is a pedagogical model created in 2012 by Jonathan Bergmann and Aaron Sams, Chemistry teachers at Woodland Park High School (Woodland Park Colorado). In this model, rather than taking up limited class time to explain a new concept (often via lecture), the teacher add a variety of learning material (videos, articles, podcast. etc.) to Blackboard before class. The objective is to introduce students to the concepts that they are going to study during class, freeing up class time for more collaborative activities. Learning material includes main concepts and ideas of the unit of study and it can be produced originally by the teacher or it can be acquired from internet. The activity has been carried out during the first semester of the academic year 2018-19 in the subjects Clinical Pharmacology and Pharmacology in Pharmacy and Medicine degrees, respectively. Acquired knowledge of students was evaluated by Kahoot tests and a survey was conducted to analyse the student’s opinion about the activity. Kahoot results showed that 80 of the students pass the test. On the other hand, based on the results of the survey, the activity proved to be very interesting for the students. The flipped classroom helped them to clarify concepts and many of them considered that having previous theoretical background is important to understand the activity, although it is not essential.
