El género Vanilla comprende alrededor de 110 especies, distribuidas en las partes tropicales del mundo, y es el continente americano donde se encuentra la mayor cantidad de especies reportadas. En ...México, el cultivo de la vainilla está relacionado con diversas culturas como la totonaca, maya, chinanteca, mazateca, entre otras. En la actualidad, este cultivo presenta factores condicionantes tales como: técnicos, económicos, sociales, ecológicos y climáticos, que limitan su producción y la conservación de especies silvestres y cultivadas, por lo que es necesario, conocer su estado actual, en relación con su diversidad, así como algunos de los principales indicadores del perfil bioclimático de cada una de las especies, que ayuden en la toma de decisiones para su conservación y mejoramiento genético. Durante 2008, se realizaron consultas a herbarios de IPN, MEXU, XAL, base de datos de la Red Mundial de Información sobre la Biodiversidad de la CONABIO (REMIB), Global Biodiversity Information Facility (GBIF) y datos de accesiones vivas del banco de germoplasma de vainilla de la BUAP, formado del 2008 al 2014. Se realizaron mapas de distribución mediante un sistema de información geográfica. Se obtuvo el perfil bioclimático de cada especie considerando 19 variables de World Clim, y altitud a una resolución espacial de aproximadamente 1 Km.sup.2. Se calcularon las medias, desviaciones estándar y varianzas de las 19 variables en cada uno de los puntos registrados. Se obtuvieron los intervalos de las condiciones ambientales extremas (mínimo, promedio y máximo) para cada una de las especies de vainilla. Para determinar las variables de mayor importancia en la distribución de las especies se realizó un análisis de componentes principales, y a las variables que resultaron significativas se les realizó pruebas de Kruskal-Wallis y Dunn. Los resultados indicaron que en México se tienen registros de V. planifolia, V pompona, V. insignis, V. inodora V. odorata, V. cribbiana y V. sprucei distribuidas en nueve estados. V. planifolia presentó intervalos amplios de temperatura y precipitación; V. pompona, V. odorata, V. insignis y V. inodora tuvieron intervalos intermedios. La amplitud de los datos extremos de cada especie puede considerarse para ubicar los sitios donde se puedan llevar a cabo estrategias regionales de conservación ex situ y el establecimiento de cultivos. El perfil bioclimático encontrado permite inferir de manera indirecta la condición genética de cada especie que podría ser utilizada en programas de mejoramiento genético como: la alta altitud y tolerancia a bajas temperaturas (V odorata), la tolerancia a altas temperaturas (V. inodora) y tolerancia a baja precipitación (V. odorata, V. pompona y V. planifolia).

The genus Vanilla comprises around 110 species distributed throughout Earth's tropical regions, with the largest number of reported species growing in the American continent. Vanilla farming is associated with many Mexican cultures such as the Totonac, Mayan, Chinantec, and Mazatec, among others. Currently, this crop is threatened by technical, social, ecological, and climatic conditioning factors, limiting its production and the preservation of wild and cultivated species. It is therefore necessary to ascertain the current diversity status of each of these species, as well as some of their main bioclimatic profile indicators, in order to help decision-making, aimed at preserving and genetically improve these species. During 2008, we gathered data from IPN, MEXU, and XAL herbaria, as well as from CONABIO's World Information Network on Biodiversity (REMIB), the Global Biodiversity and Information Facility (GBIF), and we also used data from live access to BUAP's vanilla germplasm bank, obtained between 2008 and 2014. Distribution maps were generated using a geographical information system. Bioclimatic profiles for each species were obtained considering 19 WorldClim variables and altitude at a spatial resolution of approximately 1 Km.sup.2. Variance, Mean, and standard deviation for each of the 19 variables were calculated at each of the registered points. Extreme environmental condition intervals (minimum, average, and maximum) were also obtained. In order to determine the most important distribution variables of the species, we performed a principal component analysis and carried out Kruskal-Wallis and Dunn's tests on the variables identified as significant. Results indicated records for V. planifolia, V. pompona, V. insignis, V. inodora V. odorata, V cribbiana, and V. sprucei in Mexico, distributed throughout nine states in the country. V. planifolia presented wide intervals of temperature and rain precipitation, while V. pompona, V. odorata, V. insignis and V. inodora presented intermediate intervals. The amplitudes of extreme data for each species can be considered in locating areas where ex situ regional preservation strategies could be put in place, as well as in establishing areas for cultivation. The bioclimatic profile we found, allows for an indirect inference of each species' genetic condition, which could be used in genetic improvement programs; for instance, V. odorata grows at high altitudes and tolerates low temperatures, while V. inodora tolerates high temperatures, and V. odorata, V. pompona and V. planifolia tolerate low rain precipitation. Key words: biodiversity, species, orchids, rain precipitation, temperature, altitude.

Introducción: el apego materno es el conjunto de conductas y vínculos que la madre establece en torno al recién nacido. El ingreso en la Unidad de Cuidados Intensivos Neonatales supone una barrera en ...el establecimiento de estos primeros lazos.
Objetivo: el principal objetivo del presente estudio es comparar el grado de apego valorando dicha separación, así como identificar aquellas variables que podrían influir en su establecimiento.
Material y métodos: un total de 82 madres, divididas en dos grupos (O-U), participaron en este estudio ex postfacto comparativo causal mediante la cumplimentación del cuestionario Maternal Attachment Inventory, la entrevista y la revisión de la historia clínica.
Resultados: se encontraron diferencias estadísticamente significativas en la puntuación MAI entre madres del Grupo Obstetricia (99’67) y del Grupo UCIN (91’64), del mismo modo se señaló la edad gestacional y la alimentación como factores influyentes.
Discusión y conclusión: la separación tras el ingreso en la Unidad de Cuidados Intensivos Neonatales dificulta el establecimiento de los primeros vínculos maternos. Es necesario valorar los diferentes factores que influyen en esta situación y realizar futuras intervenciones para mejorar la relación materno-filial.
A highly sensitive and specific real-time (rt) RT-PCR assay has been developed for rapid, simultaneous detection of three strains of cetacean morbillivirus (CeMV). In this assay, two PCR primers and ...a hydrolysis probe from a commercially available Universal Probe Library (UPL) are used to amplify a highly conserved region within the fusion protein gene. RT-PCR is carried out on the same sample using two primer sets in parallel: one set detects the more virulent strains, dolphin morbillivirus (DMV) and porpoise morbillivirus (PMV), and the other set detects the least virulent and least common strain, pilot whale morbillivirus (PWMV). Sensitivity analysis using dilute samples containing purified DMV, PMV and PWMV showed that viral RNA detection limits in this UPL RT-PCR assay were lower than in a conventional RT-PCR assay. Our method gave no amplification signal with field samples positive for viruses related and unrelated to CeMV, such as phocine distemper virus (PDV). The reliability and robustness of the UPL RT-PCR assay were verified using tissue samples previously analyzed by conventional methods, as well as a panel of clinical samples suspected of containing CeMV. Using the UPL RT-PCR assay, we were able to associate DMV with a mass stranding of striped dolphins in the Spanish Mediterranean in 2011 with greater reliability than was possible with a conventional RT-PCR method. These results suggest that this UPL RT-PCR method is more sensitive and specific than the conventional approach, and that it may be an affordable and rapid test for routine diagnosis of three CeMV strains.
Heart failure (HF) guidelines recommend treating all patients with HF and reduced ejection fraction (HFrEF) with quadruple therapy, although they do not establish how to start it. This study aimed to ...evaluate the implementation of these recommendations, analyzing the efficacy and safety of the different therapeutic schedules.
Prospective, observational, and multicenter registry that evaluated the treatment initiated in patients with newly diagnosed HFrEF and its evolution at 3 months. Clinical and analytical data were collected, as well as adverse reactions and events during follow-up. Five hundred and thirty-three patients were included, selecting four hundred and ninety-seven, aged 65.5 ± 12.9 years (72% male). The most frequent etiologies were ischemic (25.5%) and idiopathic (21.1%), with a left ventricular ejection fraction of 28.7 ± 7.4%. Quadruple therapy was started in 314 (63.2%) patients, triple in 120 (24.1%), and double in 63 (12.7%). Follow-up was 112 days IQI 91; 154, with 10 (2%) patients dying. At 3 months, 78.5% had quadruple therapy (p < 0.001). There were no differences in achieving maximum doses or reducing or withdrawing drugs (< 6%) depending on the starting scheme. Twenty-seven (5.7%) patients had any emergency room visits or admission for HF, less frequent in those with quadruple therapy (p = 0.02).
It is possible to achieve quadruple therapy in patients with newly diagnosed HFrEF early. This strategy makes it possible to reduce admissions and visits to the emergency room for HF without associating a more significant reduction or withdrawal of drugs or significant difficulty in achieving the target doses.
BACKGROUND: Herpesvirus and poxvirus can infect a wide range of species: herpesvirus genetic material has been detected and amplified in five species of the superfamily Pinnipedia; poxvirus genetic ...material, in eight species of Pinnipedia. To date, however, genetic material of these viruses has not been detected in walrus (Odobenus rosmarus), another marine mammal of the Pinnipedia clade, even though anti-herpesvirus antibodies have been detected in these animals. CASE PRESENTATION: In February 2013, a 9-year-old healthy captive female Pacific walrus died unexpectedly at L’Oceanografic (Valencia, Spain). Herpesvirus was detected in pharyngeal tonsil tissue by PCR. Phylogenetic analysis revealed that the virus belongs to the subfamily Gammaherpesvirinae. Poxvirus was also detected by PCR in skin, pre-scapular and tracheobronchial lymph nodes and tonsils. Gross lesions were not detected in any tissue, but histopathological analyses of pharyngeal tonsils and lymph nodes revealed remarkable lymphoid depletion and lymphocytolysis. Similar histopathological lesions have been previously described in bovine calves infected with an alphaherpesvirus, and in northern elephant seals infected with a gammaherpesvirus that is closely related to the herpesvirus found in this case. Intracytoplasmic eosinophilic inclusion bodies, consistent with poxviral infection, were also observed in the epithelium of the tonsilar mucosa. CONCLUSION: To our knowledge, this is the first molecular identification of herpesvirus and poxvirus in a walrus. Neither virus was likely to have contributed directly to the death of our animal.
With the aim of obtaining a map which is useful as a diagnostic tool and therapeutical orientation, complementing the written report of duplex ultrasound venous study, Latin-American Scientific ...Societies of Phlebology, Vascular Surgery and Vascular Imaging were invited to participate, through their regional representatives, to the First Consensus of Superficial and Perforating Venous Mapping. A consensus process using a modified Delphi method was carried out. An International Working Group was formed, which developed a Prototype of the Venous Mapping that worked as a starting point for consensus, and was presented in a first virtual meeting of 54 experts (societies' representatives) when the methodology was explained. For the consensus process, two rounds of self-administrated questionnaires with feedback were used. In the first questionnaire a 100% consensus was obtained in the 15 statements (an agreement range of 85.2% to 100%) In the analysis of qualitative data, three categories according to the actions to implement were identified - actions which involved no action, minor changes and major changes. This analysis was used to build the second questionnaire, which reached a consensus in its six statements (agreement range of 87.1% to 98.1%). A final consensus on every field proposed was established with the approval of all the experts consulted and it was presented at a third online meeting. The document of the superficial and perforating venous mapping reached by consensus is presented hereafter.
