    La investigación tuvo como principal objetivo determinar los niveles de radiación solar ultravioleta (RSUV) en el departamento Tumbes y la incidencia de las principales enfermedades relacionadas con su exposición. Para determinar los niveles de RSUV, se determinó el índice UV entre febrero del 2010 y abril del 2014; y se construyeron curvas de tendencia. Con la información de enero del 2013 a abril del 2014 se construyeron curvas de comportamiento horario del índice UV por meses; durante enero a abril del 2014 se midió la radiación en los rangos UVA/B y UVC. La información de casos de enfermedades relacionadas con la exposición a la radiación UV fue tomada de la Oficina de Estadística del Ministerio de Salud y de la Oficina de Estadística del INEN (Instituto Nacional de Enfermedades Neoplásicas) y fue sistematizada en gráficos. Los niveles de índice UV alcanzaron máximos en el año 2010, llegando a valores de 16, considerado como extremo de acuerdo a la Organización Mundial de la Salud. El 2013 fue el año con menores niveles índice UV. Es en los meses de verano se alcanzan los mayores niveles de radiación UV. Los mayores niveles de radiación UV son alcanzados entre el medio día y las 14.00 horas, en todas las épocas del año; niveles alcanzados suponen un riego sobre la salud humana. En cuanto a las enfermedades ligadas a la exposición a la radiación solar ultravioleta, los casos de catarata senil han ido en aumento en los últimos 4 años, desde menos de 10 en el 2010 hasta más de 50 en el 2013- También hay un aumento de los casos de cánceres del tipo no melanoma de 1 caso en el 2009 a 5 en el 2011

    We describe a new species of pitviper of the genus Bothrops from the Peruvian Pampas del Heath, in the Bahuaja-Sonene National Park. Pampas del Heath is an area of seasonally flooded savannas and a northwestern extension of the Gran Chaco Boliviano-Paraguayo. The new species is easily distinguished from its congeners by the exclusive combination of dorsal color pattern of body consisting of small C-shaped blotches, postocular stripe originating posteriorly to the eye, covering posterior supralabials, dorsum of the head with paired markings arranged symmetrically, venter cream heavily speckled with brown, prelacunal scale discrete in contact with second supralabial, three to five prefoveals, subfoveal single usually present, postfoveals absent to two, canthals two, seven intersupraoculars, one or two suboculars, two or three postoculars, seven or eight supralabials, nine to eleven infralabials, 26-27 interrictals, 23-25 middorsal scales, 172 ventrals in the female and 169-173 in males, 45 subcaudals in the female and 50 in males. We performed separate and combined phylogenetic analyses based on morphology and five mitochondrial genes and recovered the new species as a member of the Bothrops neuwiedi species group. All lineages of this clade inhabit the South American dry diagonal. This novel species of pitviper increases the known diversity of the genus Bothrops and adds to the number of described taxa from the unique and scarcely known ecosystem of Pampas del Heath.Fil: Carrasco, Paola Andrea.

    The genus Bartonella encompasses 38 validated species of Gram-negative, facultative intracellular bacteria that colonize the endothelial cells and erythrocytes of a wide spectrum of mammals. To date, 12 Bartonella species have been recorded infecting humans, causing diseases of long historical characterization, such as cat scratch fever and trench fever, and emerging bartonellosis that mainly affect animal health professionals. For this reason, this study aimed to report a documented case of Bartonella bovis infecting a veterinarian from Mexico by the amplification, sequencing and phylogenetic reconstruction of the citrate synthase (gltA) and the RNA polymerase beta-subunit (rpoB) genes, and to report the natural course of this infection. To our knowledge, this work is the first to report the transmission of B. bovis via needlestick transmission to animal health workers in Latin America

    Food preservation techniques have allowed seasonal foods to be consumed at any time of the year. Drying has been used for many years as a means of preservation to dry a wide variety of products. A tunnel-type solar dryer with the coupling of solar water and air heating technologies was built in the Faculty of Engineering of the Autonomous University of Campeche, located between the parallels 17°49' and 20°51' north latitude and the meridians 89°06' and 92°27' west longitude. The results of its thermal evaluation considering temperatures within the drying chamber and the climatological parameters are presented in this work. The results indicate that higher temperatures were reached with the air collector, the second-best option turned out to be the use of both technologies at the same time, and the lowest temperatures were obtained with the solar heaters of evacuated tubes, reaching 49°C, 48 °C, and 46 °C, respectively. The highest measured solar irradiation was 936.5 W/m2, the highest ambient temperature was 33.3 °C, and the lowest relative humidity was 63% at 13:00 h.  Las técnicas de conservación de alimentos han permitido que los alimentos estacionales puedan consumirse durante cualquier época del año lo cual es fundamental para garantizar la seguridad alimentaria de todos los habitantes del planeta. El secado se ha utilizado durante muchos años como medio de conservación para secar una gran variedad de productos. Se construyó un secador solar tipo túnel con acoplamiento de tecnologías de calentamiento solar de agua y aire en la Facultad de Ingeniería de la Universidad Autónoma de Campeche, ubicada entre los paralelos 17°49' y 20°51' de latitud norte y los meridianos 89°06' y 92°27' de longitud oeste; se presentan en este trabajo los resultados de su evaluación térmica considerando temperaturas dentro de la cámara de secado y los parámetros climatológicos. Los resultados indican que se alcanzaron mayores temperaturas con el colector de aire, la segunda mejor opción resultó ser la utilización de ambas tecnologías al mismo tiempo y las temperaturas más bajas se obtuvieron con los calentadores solares de tubos evacuados, alcanzando 49 °C, 48 °C y 46 °C, respectivamente.

    Background: Previous studies have demonstrated the feasibility of using an asthma app to support medication management and adherence but failed to compare with other measures currently used in clinical practice. However, in a clinical setting, any additional adherence measurement must be evaluated in the context of both the patient and physician perspectives so that it can also help improve the process of shared decision making. Thus, we aimed to compare different measures of adherence to asthma control inhalers in clinical practice, namely through an app, patient self-report and physician assessment. Methods: This study is a secondary analysis of three prospective multicentre observational studies with patients (≥13 years old) with persistent asthma recruited from 61 primary and secondary care centres in Portugal. Patients were invited to use the InspirerMundi app and register their inhaled medication. Adherence was measured by the app as the number of doses taken divided by the number of doses scheduled each day and two time points were considered for analysis: 1-week and 1-month. At baseline, patients and physicians independently assessed adherence to asthma control inhalers during the previous week using a Visual Analogue Scale (VAS 0-100). Results: A total of 193 patients (72% female; median [P25-P75] age 28 [19-41] years old) were included in the analysis. Adherence measured by the app was lower (1 week: 31 [0-71]%; 1 month: 18 [0-48]%) than patient self-report (80 [60-95]) and physician assessment (82 [51-94]) (p 0.05). There was a moderate correlation between patient self-report and physician assessment (ρ = 0.596, p < 0.001). Conclusions: Adherence measured by the app was lower than that reported by the patient or the physician. This was expected as objective measurements are commonly lower than subjective evaluations, which tend to overestimate adherence. Nevertheless, the low adherence measured by the app may also be influenced by the use of the app itself and this needs to be considered in future studies.info:eu-repo/semantics/publishedVersio

    8 páginas, 4 tablas, 8 figuras.The effect of salinity level and extended exposure to different salinity and flooding conditions on germination patterns of three saltmarsh clonal growth plants (Juncus subulatus, Scirpus litoralis, and S. maritimus) was studied. Seed exposure to extended flooding and saline conditions significantly affected the outcome of the germination process in a different, though predictable, way for each species, after favorable conditions for germination were restored. Tolerance of the germination process was related to the average salinity level measured during the growth/germination season at sites where established individuals of each species dominated the species cover. No relationship was found between salinity tolerance of the germination process and seed response to extended exposure to flooding and salinity conditions. The salinity response was significantly related to the conditions prevailing in the habitats of the respective species during the unfavorable (nongrowth/nongermination) season. Our results indicate that changes in salinity and hydrology while seeds are dormant affect the outcome of the seed-bank response, even when conditions at germination are identical. Because these environmental-history-dependent responses differentially affect seed germination, seedling density, and probably sexual recruitment in the studied and related species, these influences should be considered for wetland restoration and managementFinancial support from the Spanish Ministry of the Environment (MMA, project 05/99) and the Junta de Andalucía (research group 4086)enabled us to carry out the present work.Peer reviewe
