Background: Aging increases the vulnerability to diseases and environmental changes such as the COVID-19 pandemic. Telehealth and tele-education are vital to prevent the deleterious effects of prolonged confinement, and to train the community, and constantly rotating medical students and health professionals. Aim: To assess the perception and impact of an online course about healthy aging aimed at the community and health care professionals. Material and Methods: An open online one-day course to promote healthy aging was carried out. A cross-sectional online survey about the course was answered by 386 attendants and a knowledge test was applied to 114 people. Results: Seventy-five percent of respondents attended the course synchronously. Of these, 79% were women, 20% were older people and 53% were caregivers of an older person. All respondents acquired new knowledge and were willing to participate again. The frequency of interest about self-care is three times greater than about caring for another person, In an older person, the interest is 101 more times about self-care than caring for another person. Ninety five percent of respondents felt more active and 84% felt more accompanied. Conclusions: The course facilitated access to information on the promotion of active and healthy aging in the community with a favorable perception and a positive impact. The coverage for older people with a digital gap should be improved.

Abstract Gastrointestinal parasites are well-documented in small mammals from north-central Chile, but little is known about endoparasites of rodents in southern Chile. A survey was conducted between January and February 2018 to evaluate gastrointestinal parasites and risk factors of wild rodents that live in rural areas in Northern Chiloé Island, Chile. A total of 174 fecal samples from rodents of six native and one introduced species were collected and examined using the Mini-FLOTAC method. Also, 41 individuals of four native wild rodent species were examined furtherly to determinate adult parasites from gastrointestinal tracts. The overall prevalence of endoparasites was 89.65% (156). Helminth egg types included: Rodentolepis spp., Capillariidae, Trichuris sp., Syphacia sp., oxyurid-type eggs, Strongyloides sp., Spirurid-type eggs, Strongilid-type eggs, Moniliformis sp., and an unidentified nematode egg and larvae. Protozoa comprised coccidia, amoeba, and unidentified cysts. From necropsies, adult parasites involved Syphacia sp. Trichuris sp., Protospirura sp. and Physaloptera sp. In Abrothrix olivacea, individuals with low-body-mass index exhibited reduced infection probability for Spirurid-type and Strongilid-type eggs. Some parasites in this study may affect human health. In rural settings where environmental conditions are changing, more research should be undertaken to understand parasitic infections in wildlife and implications for public health and conservation.

Resumo Parasitos gastrointestinais são bem documentados em pequenos mamíferos do centro-norte do Chile, mas pouco conhecido sobre endoparasitos de roedores no sul do Chile. Uma pesquisa foi realizada entre janeiro e fevereiro de 2018, avaliando parasitas gastrointestinais e fatores de risco de roedores selvagens vivendo em áreas rurais no norte da Ilha de Chiloé, Chile. Um total de 174 amostras fecais de roedores de seis espécies nativas e uma introduzida foi coletado e examinado pelo método Mini-FLOTAC. Ademais, 41 indivíduos de quatro espécies nativas de roedores selvagens foram examinados para determinar parasitas adultos do trato gastrointestinal. A prevalência geral de endoparasitos foi de 89,65% (156). Os tipos de ovos de helmintos incluíram: Rodentolepis spp., Capillariidae, Trichuris sp., Syphacia sp.; dos tipos Oxyurideos, Strongyloides sp., dos tipos Spirurideos e Estrongilideos, Moniliformis sp.; e um ovo e larvas de nematoides não identificados. Os protozoários compreendiam coccídios, amebas e cistos não identificados. Nas necropsias, os parasitos adultos envolveram Syphacia sp. Trichuris sp., Protospirura sp. e Physaloptera sp. Em Abrothrix olivacea, indivíduos com baixo índice de massa corporal apresentaram probabilidade de infecção reduzida para ovos Spirurideos e Estrongilideos. Alguns parasitos, neste estudo, podem afetar a saúde humana. Em ambientes rurais, onde as condições ambientais mudam, mais pesquisas são necessárias para entender as infecções parasitárias na vida selvagem e as implicações para a saúde pública e conservação.

Background: Undergraduate Pathology training in medicine is based on modalities centered on the teacher and associated with controlled motivation, with low satisfaction with the educational process. According to the Self-determination Theory, an early participation with responsibilities in clinical practice and an educational environment that promotes autonomy and basic psychological needs satisfaction (BPNS), would generate intrinsic motivation. Aim: To develop an educational intervention based on the pathologists' workplace model, which supports a learning environment intended to the satisfaction of BPNS in medical students. To evaluate the results of the intervention on the levels of motivation and satisfaction. Material and Methods: In the first phase of the study, an educational modality focused on the student was planned, consisting of the design of a pathological clinical case (DPC), performing the specialist's steps under minimal supervision and a contextualized environment. In the second phase, the level of satisfaction (Scale of student experience) and intrinsic motivation in 3rd year medical students was evaluated. Results: After the intervention, 99 students showed high levels of satisfaction (94% of agreement) and intrinsic motivation (6.7 of 7 points), including all sub-scales. They considered that their competences had increased and assessed the intervention as useful. Conclusions: DPC is an innovative, feasible and attractive methodology for Pathology learning, with a high degree of satisfaction and intrinsic motivation. This experience can be extended to similar disciplines.

Permanent and permeable edges, where natural enemies can feed, overwinter or easily cross over, should enhance the early arrival of these predators to crops. We evaluated the abundance and species richness of coccinellids migrating to alfalfa fields adjacent to Eucalyptus, a mix of false acacia, blackberries and poplar (F-B-P), vineyards, corn and annual vegetables. From September 2007 to May 2008, we captured coccinellids in three sticky traps (2.64 m²) placed at the borders between alfalfa fields and adjacent vegetation. We also estimated the abundance of aphid populations in the alfalfa fields, by counting the number of individuals per alfalfa stem in spring, summer and autumn. We collected 90,396 coccinellids from 14 species. Neither total abundance nor species richness of coccinellids was significantly affected by adjacent vegetation, but Adalia deficiens, Psyllobora picta and Cycloneda sanguínea were more abundant in alfalfa adjacent to Eucalyptus and F-B-P, meanwhile Olla v-nigrum next to annual crops and Hyperaspis sphaeridioides next to vineyards. Edge height and orientation explained 94% of the variance in species abundance. Particularly, P. picta and O. v-nigrum were positively and negatively influenced by border height, respectively. Hyperaspis sphaeridioides was negatively affected by northern exposure and none of the species was affected by edge permeability. Aphids were less abundant in alfalfa fields adjacent to F-B-P, especially in spring. These results show that most species of coccinellids were not affected by the composition of crop edges, although tall permanent edges may enhance the arrival of particular coccinellid species to alfalfa fields.

Bordes permanentes y permeables favorecerían la llegada de los enemigos naturales a los cultivos. Se evaluó la abundancia y riqueza de especies de coccinélidos migrando a campos de alfalfa adyacentes a Eucalyptus, una mezcla de Falsa acacia, zarzamoras y álamos (F-B-P), viñas, maíz y cultivos anuales bajos. También se estimó la abundancia de áridos en los campos de alfalfa. Entre septiembre 2007 y mayo 2008, los coccinélidos fueron capturados en tres trampas pegajosas (2,64 m²) ubicadas en el borde de cada alfalfal; la abundancia de áfidos dentro de los alfalfales se estimó en primavera, verano y otoño. Se colectaron 90.396 coccinélidos de 14 especies. Ni la abundancia total ni la riqueza de especies de coccinélidos fueron significativamente afectados por el tipo de vegetación adyacente, pero Adalia deficiens, Psylloborapicta y Cycloneda sanguínea fueron más capturadas en campos de alfalfa adyacentes a Eucalyptus y F-B-P, Olla v-nigrum cerca de cultivos anuales e Hyperaspis sphaeridioides cerca de viñas. La altura y orientación de los bordes explican el 94% de la varianza de la abundancia de especies. Psyllobora picta fue positivamente influenciada por la altura, O. v-nigrum negativamente e Hyperaspis sphaeridioides negativamente afectada por la exposición norte; ninguna de las especies fue afectada por la permeabilidad del borde. Los áfidos fueron menos abundantes en alfalfales cercanos a F-B-P. En general, la mayoría de las especies de coccinélidos no fueron afectadas por el tipo de borde, pero los bordes altos y permanentes facilitan la llegada de algunas especies de coccinélidos a los campos de alfalfa.
