The Tehuacán-Cuicatlán Valley is a region of outstanding biocultural diversity, harboring eight indigenous ethnic groups and a remarkable biodiversity in a territory 10,000 km
extent. Ethnobotanical ...studies of the region are among the most complete in Mexico; contrarily, ethnozoological studies are still limited. But information on both flora and fauna use and management is relevant for understanding local cultural and ecological issues, and for planning integral strategies of biodiversity conservation. Our study focused on analyzing knowledge and use of animals and their relationship with faunistic management by the Cuicatec, an ancient human culture whose distribution is restricted to the region. We hypothesized that wild animals still have significant contributions to diet, medicine, and spiritual life of the Cuicatec people. In addition, we expected to find a gradient of interactions, from simple gathering and hunting to communitarian regulations of use, specialized management techniques and care, nurturing, and domestication of animals. Such gradient of management interactions would be influenced proportionally with cultural and economic values, viability maintenance, and scarcity of animals.
Our study was carried out in San Lorenzo Pápalo, Oaxaca. We conducted surveys and semi-structured and open interviews to people to document the Cuicatec nomenclature, classification, use, and management of fauna, as well as their perceptions about abundance, risks of disappearance, and availability of wild animals. We used images of animal species reported for the area as communication stimuli for confirming their local presence. Also, we recorded skins and skulls used as trophies and ornamental objects, pawprints, and excretes. Through free listing, we identified the most meaningful species of different animal groups. Whenever possible, we evaluated amounts of animals obtained from the wild, and for some species, we compared this information with data on their distribution and abundance evaluated through ecological sampling, to explore indicators on their sustainable use.
The Cuicatec name all animals through the term i-ti and classify them in several groups of vertebrates, arthropods, and mollusks, some of them coinciding with the formal taxonomy and some others based on their social-cultural role. The most meaningful animals are 23 species of edible organisms, outstandingly the chicatana ants (Atta mexicana) and the cuetla Lepidoptera larvae (Arsenura armida), the lizard Sceloporus grammicus, and among the mammals some squirrels (Sciurus spp.), badgers (Nasua narica), and deer (Odocoileus virginianus). Some species were reported to be used for medicinal purposes, among them opossum (Didelphis spp.) and macaws (Ara militaris), used to ease childbirths, but this use almost disappeared. Local perception of availability of animal resources is associated to forest conservation. Regulations for protecting forests and the most used animal species were recorded; the rules are mainly associated to hunting and gathering seasons, respecting females of vertebrate species, and permits for gathering and hunting given by local authorities. Nurturing of animals was recorded in bird and mammal species, but in no case, their breeding was achieved.
Animals are important elements of the Cuicatec culture and subsistence, complementing their diet based on agricultural products. Animals used as medicine were still reported but substituted by modern medicine. There is a consensus about the need to conserve forests to ensure the maintenance of animals, which are valued as part of nature, the beauty of their territory, and culture. Communitarian regulations are the main ways for conserving fauna, but local techniques of animal management may help in designing conservation strategies.
Acknowledgement of COPD underdiagnosis and misdiagnosis in primary care can contribute to improved disease diagnosis. PUMA is an international primary care study in Argentina, Colombia, Venezuela and ...Uruguay.
To assess COPD underdiagnosis and misdiagnosis in primary care and identify factors associated with COPD underdiagnosis in this setting.
COPD was defined as post-bronchodilator (post-BD) forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) <0.70 and the lower limit of normal (LLN). Prior diagnosis was self-reported physician diagnosis of emphysema, chronic bronchitis, or COPD. Those patients with spirometric COPD were considered to have correct prior diagnosis, while those without spirometric criteria had misdiagnosis. Individuals with spirometric criteria without previous diagnosis were considered as underdiagnosed.
1,743 patients were interviewed, 1,540 completed spirometry, 309 (post-BD FEV1/FVC <0.70) and 226 (LLN) had COPD. Underdiagnosis using post-BD FEV1/FVC <0.70 was 77% and 73% by LLN. Overall, 102 patients had a prior COPD diagnosis, 71/102 patients (69.6%) had a prior correct diagnosis and 31/102 (30.4%) had a misdiagnosis defined by post-BD FEV1/FVC ≥0.70. Underdiagnosis was associated with higher body mass index (≥30 kg/m2), milder airway obstruction (GOLD I-II), black skin color, absence of dyspnea, wheezing, no history of exacerbations or hospitalizations in the past-year. Those not visiting a doctor in the last year or only visiting a GP had more risk of underdiagnosis. COPD underdiagnosis (65.8%) and misdiagnosis (26.4%) were less prevalent in those with previous spirometry.
COPD underdiagnosis is a major problem in primary care. Availability of spirometry should be a priority in this setting.

Este artículo parte de una noción de poder, desde algunas perspectivas que incluyen dispositivos, mecanismos y modalidades del poder. Tiene como objetivo analizar la relación entre los postulados de ...poder y algunos aspectos de la educación colombiana, en particular, de la correspondencia entre formación laboral y la reproducción del orden ideológico estatuido. El tipo de investigación se aproxima al análisis crítico del discurso y se desarrolla desde un enfoque cualitativo, mediante un método dialógico entre las teorías del poder de Foucault (1988, 2002) y de Althusser (1969, 1971, 1988) –corpus-, en torno de seis postulados principales básicos. Las oposiciones y complementariedades que estas dos teorías presentan acerca del poder surgen, especialmente, porque se han pensado dentro de marcos institucionales, tales como las escuelas (Foucault, 2002) y la ineludible relación con las ideologías y políticas estatales (Althusser, 1988). Como resultados, se muestran las disparidades y confrontaciones entre estas dos teorías sobre poder. La conclusión permite observar las relaciones que se dan entre estado y los escenarios escolares públicos, así como la forma en que funcionan los dispositivos de poder en estos escenarios (Jäger, 2003), siempre desde la posibilidad de la esperanza humana de transformar su entorno.
This work examines the development of ethnobotany, focusing on Mexico in this millennium. How has the discipline grown? What is the relative importance of Spanish? Are there inflection points? How ...did some select areas develop, and why? Numerical growth was analyzed mainly through Google Scholar queries. Other subjects were treated based on literature and experience of the authors. Spanish continues to be relevant, especially in Mexico. The discipline gained momentum from 2000 onwards because of the social context of the 1990s, the publication of several foundational works, methodological advances, and particularities of Mexican science. The trajectory of ethnobotany is congruent with a model derived from Kuhn’s proposal of cyclical advancement of science: an initial defining stage was followed by a first synthesis, then fast growth of descriptive studies, with a notable recent turn to theory and framework construction. The causes for advances are discussed for three areas (medicinal plants, agriculture, and wild-growing resources). General interest, financing, the consolidation of research groups and the internal organization of institutions have played a role. We highlight important open questions. Ethnobotany is maturing from a descriptive to an analytical stage. However, careful descriptive studies continue to be valuable because the sources of information are in decline, and theory needs an empirical basis. Also, ethnobotany encourages the transmission of knowledge and biocultural memory. It is a key element for integrated sustainability science.
Background
Malnutrition status, body composition indicators, and bioelectrical impedance analysis (BIA) parameters have been associated with increased risk of death in several pathologies. The aim of ...this study was to describe the associations between phase angle (PhA) indicators obtained by BIA with length of hospital stay, days on mechanical ventilation, and 60‐day mortality in critically ill patients infected with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2).
Methods
This is a prospective cohort of mechanically ventilated patients with coronavirus disease 2019 (COVID‐19). We assessed nutrition risk and body composition with BIA within 48 h from intensive care unit admission. Logistic and linear regression models were used to analyze the association between variables and clinical outcomes. Survival analysis by PhA value was performed using Kaplan‐Meier curves.
Results
Sixty‐seven patients were included. PhA (odds ratio OR, 0.36; P = .002), standardized PhA (SPA) (OR, 0.45; P = .001), and extracellular water/total body water ratio (OR, 3.25; P = .002) were significant predictors of 60‐day mortality. PhA <3.85° in females and <5.25° in males showed good and fair discrimination, respectively, for mortality prediction. Using cutoff values, low PhA was associated with a significantly increased risk of 60‐day mortality (hazard ratio, 3.08; 95% CI, 1.12–8.41; P = .02). No association was detected for SPA.
Conclusion
Low PhA values could be a predictor of 60‐day mortality in critically ill patients with COVID‐19. This biological marker could be incorporated as part of nutrition and mortality risk assessment in this population.
Abstract Background Historically, the Andean people have experienced uncertainty in terms of the availability of food resources because of climatic and ecological variations that are typical of ...mountainous environments. Risk management strategies, including the diversified and complementary use and management of species and ecosystems at different elevations, have faced such uncertainty. The current effects of climate change on food security motivate studies on subsistence adaptative strategies. TEK offers extraordinary experience and local biocultural memory to meet present and future needs. From an ethnoecological perspective, we aim to identify the variety of local foods in Andean communities, their cultural and nutritional value for local people, their use frequencies, and their forms to obtain them from different environments, productive systems, and interchanges. We expected to identify traditional Andean diversified subsistence patterns despite the pressure of modern food and interchange systems. Methods This study was conducted in two communities in the highlands of the Department of Huánuco, Peru. We conducted 24 semistructured interviews with households sampled through the snowball method. We asked about their daily life food, plant and animal components of diet, frequencies and seasons in which they are consumed, and ways to obtain them. We complemented the information through ethnobotanical collection of wild, weedy, and ruderal edible plants and records on domestic and wild animals included in the diet. Results We recorded 37 crop species, 13 domestic animals, 151 wild, weedy, and ruderal food plant species, the 3 most commonly consumed wild animals, and 52 processed products obtained from local stores and markets. The main crops are potato and maize, while the main domestic animals included in the diet are cattle, pigs, and sheep. Rice, pasta, and bread are the main raw and processed foods included in the diet. Crops represent nearly half of the food consumed and purchased (in kg/year), and tubers and cereals provide most of the kilocalories, carbohydrates and proteins. Wild, weedy, and ruderal plants are consumed in relatively low amounts and at relatively low frequencies per species, but overall, they constitute a significant proportion of the kg of annually consumed food (14.4% in Cani and 9.6% in Monte Azul). Knowledge and use of these resources play a key role in local cuisine and nutrition. Conclusion The current food patterns studied are based on diverse diets, including multiple feedstuffs, sources, and practices to obtain them, which reflects the traditional Andean subsistence pattern. The increasing adoption of processed food has influenced the declining consumption of local food, mainly among young people. Communication and policies to promote local food, emphasizing the role of wild plants and their adequate consumption, and provide information on their nutritional value are recommended to support efforts toward food sovereignty and conservation of Andean biocultural diversity.
El espacio arquitectónico es relevante en el proceso de enseñanza-aprendizaje; en este sentido, la pedagogía Reggio Emilia considera el espacio como el tercer maestro. En este trabajo se ...identificaron las premisas arquitectónicas del modelo pedagógico, se desarrollaron instrumentos de evaluación y se aplicaron a casos de estudio. Seis escuelas en diferentes países fueron evaluadas. La escuela localizada en Japón obtuvo el mayor puntaje (16/17), mientras que un caso de estudio localizado en México obtuvo la menor puntuación (10/17). Resultados globales mostraron que el contacto con el exterior fue la premisa con mayor puntaje (100%); en segundo lugar, conexión con la naturaleza (72%), y en tercer lugar la incorporación de un espacio plaza (63%). La información sobre proyectos que incorporen las premisas arquitectónicas de la pedagogía Reggio Emilia, así como su evaluación, es escasa, por lo que es necesario difundir y analizar estos espacios educativos y desarrollar instrumentos de evaluación.
Agave inaequidens and A. cupreata are wild species with some populations under incipient management, while A. hookeri is exclusively cultivated, used for producing the fermented beverage pulque. ...These species are closely related and sympatric members of the Crenatae group, but taxonomists have previously hypothesized that A. inaequidens is the most probable ancestor of A. hookeri. Our study aims at evaluating patterns of morphological and genetic divergence among populations of the three species, in order to analyze their ecological and possible evolutionary relationships. We studied 24 agave populations, 16 of them of Agave inaequidens, four of A. cupreata and four of A. hookeri. Population morphometric and genetics studies were performed using 39 morphological characters and 10 nuclear microsatellites, respectively. We estimated levels of morphological and genetic diversity and dissimilarity, as well as genetic structure and gene flow among populations and species. The three species were clearly differentiated by general plant size, lateral teeth, terminal spines, flowers and fruit size. The largest plants were those of A. hookeri followed by A. inaequidens and the smallest were A. cupreata. Multivariate analyses indicated greater morphological similarity between A. hookeri and cultivated A. inaequidens, while A. cupreata consistently appeared as a separate group. We identified similar levels of morphological diversity index (MDI) in the three species, but higher genetic diversity in A. inaequidens (MDI = 0.401-0.435; HE = 0.704-0.733), than in A. cupreata (MDI = 0.455-0.523; HE = 0.480-0.510) and the predominantly vegetative propagated crop A. hookeri (MDI = 0.335-0.688; HE = 0.450-0.567), a pattern consistent with our expectations. The morphological and genetic similarities between cultivated A. inaequidens and A. hookeri support the hypothetical evolutionary relationships among these species, but studies with cpDNA and SNPs, and including other member of the Crenatae group are necessary to further resolve these relationships.

Summary
Introduction
The aim of analysing the usefulness of the blood eosinophil count (BEC) as a prognostic marker in exacerbations of patients with Chronic Obstructive Pulmonary Disease (COPD), ...evaluating its relationship with hospital mortality, the length of stay and the early and late re‐admissions.
Materials and Methods
We have carried out a retrospective study including all patients who required hospital admission from 1 January 2008 to 31 December 2009, with a diagnosis on hospital discharge of COPD exacerbation. These patients were classified using three cut‐off points of BEC: less than 200 vs ≥ 200/µL, less than 300 vs ≥ 300/µL and less than 400 vs ≥ 400/µL.
Results
There were a total of 1626 hospital admissions during the study period with the diagnosis of exacerbation of COPD. In this study we have included 358 patients. The probability of any late re‐admission increased with a BEC ≥ 300/µL (odds ratio: 1.684) and for those with a BEC ≥ 400/µL (odds ratio: 2.068). The BEC does not appear to be related to hospital mortality or the probability of early re‐admission after an exacerbation of COPD.
Conclusions
In our study an elevated BEC is associated with a higher incidence of late hospital readmissions in COPD exacerbations.
What’s known
In the last few years, the eosinophils have been recognised as an important mediator in patients with chronic obstructive pulmonary disease (COPD).
The impact of blood eosinophil count on the prognosis of COPD exacerbations is still under debate.
What’s new
In our study, which includes a large sample size, an elevated blood eosinophil count is associated with a higher incidence of late hospital readmissions in COPD exacerbations.
Infrared thermography (IRT) is a non-ionizing, non-invasive technique that permits evaluating the comfort levels of animals, a topic of concern due to the growing interest in determining the state of ...health and welfare of production animals. The operating principle of IRT is detecting the heat irradiated in anatomical regions characterized by a high density of near-surface blood vessels that can regulate temperature gain or loss from/to the environment by modifying blood flow. This is essential for understanding the various vascular thermoregulation mechanisms of different species, such as rodents and ruminants' tails. The usefulness of ocular, nasal, and vulvar thermal windows in the orbital (
), nasal (
), and urogenital (r
) regions, respectively, has been demonstrated in cattle. However, recent evidence for the river buffalo has detected discrepancies in the data gathered from distinct thermal regions in these large ruminants, suggesting a limited sensitivity and specificity when used with this species due to various factors: the presence of hair, ambient temperature, and anatomical features, such as skin thickness and variations in blood supplies to different regions. In this review, a literature search was conducted in Scopus, Web of Science, ScienceDirect, and PubMed, using keyword combinations that included "infrared thermography", "water buffalo", "river buffalo" "thermoregulation", "microvascular changes", "lacrimal caruncle", "udder", "mastitis", and "nostril". We discuss recent findings on four thermal windows-the orbital and nasal regions, mammary gland in the udder region (
), and vulvar in the urogenital region (
)-to elucidate the factors that modulate and intervene in validating thermal windows and interpreting the information they provide, as it relates to the clinical usefulness of IRT for cattle (
) and the river buffalo (
).
