Actualidad de las Plantas Medicinales en Terapéutica

RESUMENLas plantas medicinales han sido utilizadas por el hombre desde tiempo inmemorial para el alivio o curación de sus enfermedades. En la actualidad no solo se utilizan como punto de partida para la obtención de medicamentos industriales sino que mantienen plena vigencia para el tratamiento de numerosas dolencias. A pesar de su origen natural no están exentas de riesgos para la salud pues algunas provocan reacciones adversas e interacciones con otros fármacos que hay que tener en cuenta.En el presente trabajo se repasan las principales plantas medicinales, de gran utilidad terapéutica y amplio uso, clasificadas de acuerdo con los sistemas funcionales sobre los que actúan.Palabras claveFitoterapia, medicamentos, acción farmacológica, principios activos, interacciones medicamento-planta medicinal. ABSTRACTMedicinal plants have been used for the relief or cure of several diseases for centuries. Most of the medicines we used today are derived straight from plants and medicinal plants are used as a drug themselves, with great utility in therapeutics. Despite their natural origin, herbal drugs are not free of side effects or interactions with other drugs that must be taken into account.This study review the efficacy and safety of the most used medicinal plants classified according to the functional systems where they act.Key words:Phytotherapy, medicines, pharmacological action, active principles, interactions drug-medicinal plant

Facing COVID-19: Situation of People with Autism and their Families in Latin America

We present a multicenter study conducted through an online survey of 1826 families of people with ASD from Argentina, Brazil, Chile, Mexico, Peru, the Dominican Republic, Uruguay and Venezuela. Our objective is to describe the impact of the pandemic –and social isolation– on the behavior, mood, sleep and diet of people with ASD. To this end, we have surveyed sociodemographic and housing characteristics and the modality of confinement. We analyze the effects of discontinuity in educational and therapeutic services and assess the scope of remote interventions. Some of the consequences of confinement –obligatory for the majority– has been increased irritability in people with ASD, increased wandering behavior, higher levels of anxiety, and difficulties in eating, sleeping and concentrating. Most of the families have noticed setbacks in their children during the confinement. The beneficial effects of outings and walks are highlighted. Many treatments and classes have been discontinued. Remote interventions are positively highlighted. The current crisis should be an opportunity to reorganize education and treatment devices, attending to the need for changes, with a more ecological, inclusive and autism-friendly perspective.Presentamos un estudio multicéntrico realizado a través de una encuesta en línea a 1826 familias de personas con TEA de Argentina, Brasil, Chile, México, Perú, República Dominicana, Uruguay y Venezuela. Nuestro objetivo es describir el impacto de la pandemia –y el aislamiento social– en la conducta, el estado de ánimo, el sueño y la alimentación de las personas con TEA. A tal fin hemos relevado características sociodemográficas, habitacionales y modalidad de confinamiento. Analizamos los efectos de la discontinuidad de los servicios educativos y terapéuticos y valoramos los alcances de las intervenciones a distancia. Algunas de las consecuencias del confinamiento –obligatorio para la mayoría– han sido el aumento de irritabilidad en las personas con TEA, el incremento de la conducta de deambular, mayores niveles de ansiedad, dificultades en alimentación, sueño y concentración. La mayor parte de las familias han notado retrocesos en sus hijos durante el encierro. Se destacan los efectos beneficiosos de salidas y paseos. Muchos tratamientos y clases se han suspendido. Se subrayan positivamente las intervenciones a distancia. La crisis actual debería ser una oportunidad para reorganizar dispositivos de educación y tratamiento, atendiendo a la necesidad de cambios, con una perspectiva más ecológica, inclusiva y amigable con el autismo

Relevance of gastrointestinal manifestations in a large Spanish cohort of patients with systemic lupus erythematosus: what do we know?

SLE can affect any part of the gastrointestinal (GI) tract. GI symptoms are reported to occur in >50% of SLE patients. To describe the GI manifestations of SLE in the RELESSER (Registry of SLE Patients of the Spanish Society of Rheumatology) cohort and to determine whether these are associated with a more severe disease, damage accrual and a worse prognosis. METHODS: We conducted a nationwide, retrospective, multicentre, cross-sectional cohort study of 3658 SLE patients who fulfil =4 ACR-97 criteria. Data on demographics, disease characteristics, activity (SLEDAI-2K or BILAG), damage (SLICC/ACR/DI) and therapies were collected. Demographic and clinical characteristics were compared between lupus patients with and without GI damage to establish whether GI damage is associated with a more severe disease. RESULTS: From 3654 lupus patients, 3.7% developed GI damage. Patients in this group (group 1) were older, they had longer disease duration, and were more likely to have vasculitis, renal disease and serositis than patients without GI damage (group 2). Hospitalizations and mortality were significantly higher in group 1. Patients in group 1 had higher modified SDI (SLICC Damage Index). The presence of oral ulcers reduced the risk of developing damage in 33% of patients. CONCLUSION: Having GI damage is associated with a worse prognosis. Patients on a high dose of glucocorticoids are at higher risk of developing GI damage which reinforces the strategy of minimizing glucocorticoids. Oral ulcers appear to decrease the risk of GI damage. © The Author(s) 2021. Published by Oxford University Press on behalf of the British Society for Rheumatology

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Antimalarials exert a cardioprotective effect in lupus patients: Insights from the Spanish Society of Rheumatology Lupus Register (RELESSER) analysis of factors associated with heart failure.

Factors associated with chronic heart failure (CHF) in patients with systemic lupus erythematosus (SLE) have received little attention. Recent data on the use of hydroxychloroquine in the treatment of SARS-CoV-2 infection have cast doubt on its cardiac safety. The factors associated with CHF, including therapy with antimalarials, were analyzed in a large multicenter SLE cohort. Cross-sectional study including all patients with SLE (ACR-1997 criteria) included in the Spanish Society of Rheumatology Lupus Register (RELESSER), based on historically gathered data. Patients with CHF prior to diagnosis of SLE were excluded. A multivariable analysis exploring factors associated with CHF was conducted. The study population comprised 117 patients with SLE (ACR-97 criteria) and CHF and 3,506 SLE controls. Ninety percent were women. Patients with CHF were older and presented greater SLE severity, organ damage, and mortality than those without CHF. The multivariable model revealed the factors associated with CHF to be ischemic heart disease (7.96 [4.01-15.48], p  Patients with SLE and CHF experience more severe SLE. Treatment with antimalarials appears to confer a cardioprotective effect
