Modeling the Perception of Public Safety

Studies related to employment expectations after a change in the political regime show a prevalence contrary to pro-government policies. The objective of this work has been to explore the structure of categories focused on expectations towards governments, entrepreneurship and training reported in the literature. A documentary study was carried out with information sources indexed to international repositories, considering the keywords of model, employment and expectations, as well as their publication in the period from 2010 to 2021. A spurious relationship was observed between the informative extracts and the categories and between the latter, but also a trend towards the structure of the relationship between training and employment expectations, excluding the expectations of employment policies, which suggests the extension of the same to a category that the literature identifies as income expectations and price inflation

Known by the company we keep: `Triadic influence' as a proxy for compatibility in social relationships

Networks of social interactions are the substrate upon which civilizations are built. Often, we create new bonds with people that we like or feel that our relationships are damaged through the intervention of third parties. Despite their importance and the huge impact that these processes have in our lives, quantitative scientific understanding of them is still in its infancy, mainly due to the difficulty of collecting large datasets of social networks including individual attributes. In this work, we present a thorough study of real social networks of 13 schools, with more than 3,000 students and 60,000 declared positive and negative relations, including tests for personal traits of all the students. We introduce a metric -- the `triadic influence' -- that measures the influence of nearest-neighbors in the relationships of their contacts. We use neural networks to predict the relationships and to extract the probability that two students are friends or enemies depending on their personal attributes or the triadic influence. We alternatively use a high-dimensional embedding of the network structure to also predict the relationships. Remarkably, the triadic influence (a simple one-dimensional metric) achieves the highest accuracy at predicting the relationship between two students. We postulate that the probabilities extracted from the neural networks -- functions of the triadic influence and the personalities of the students -- control the evolution of real social networks, opening a new avenue for the quantitative study of these systems

Utilidad del ultrasonido gástrico para predecir una cámara gástrica llena antes de la endoscopia superior

Introducción: La visualización clara de la superficie de la mucosa gastrointestinal es esencial para una endoscopia superior completa, debido a que puede disminuir la necesidad de manipulaciones adicionales que consumen tiempo, como el lavado y la succión frecuentes. Además, un "estómago lleno" es un factor de riesgo importante para la aspiración bajo anestesia. El ultrasonido gástrico (USG) se he posicionado como una herramienta para valorar de forma objetiva el contenido gástrico, ya que puede diferenciar un estómago vacío de uno que contiene líquido claro, líquido espeso o contenido de partículas sólidas basándose en hallazgos cualitativos. La incidencia de un “estómago lleno” ha sido reportada en 6.2% en pacientes sometidos a cirugía electiva bajo anestesia general. Métodos: el objetivo primario fue evaluar la sensibilidad, especificidad, y valores predictivos de los hallazgos del USG con respecto al contenido gástrico tomando como referencia los hallazgos endoscópicos. Se utilizó la fórmula de cálculo de muestra para pruebas diagnósticas. Esperando una significancia del 5% y poder del 95%, se necesita un mínimo de 61 sujetos de estudio. La sensibilidad se tomó del 99% para detectar un estómago lleno basado en el artículo Kruisselbrink R. et al (2019). Se incluyeron pacientes mayores de 18 años de edad que acudan a una endoscopía superior con ayuno de 2 horas para líquidos y 6 horas para sólidos. Previo a la endoscopia se realizará un ultrasonido gástrico con un transductor Butterfly iQ™. Se realizará un escaneo en la posición supina y posteriormente en decúbito lateral derecho. El transductor será puesto en plano sagital en la región epigástrica para poder visualizar el antro gástrico en medio del lóbulo hepático izquierdo y el páncreas, al nivel de la aorta. Se medirá el área transversal del antro gástrico en ambas posiciones. Teniendo una indicación clara previamente establecida en la consulta, la endoscopia será llevada a cabo de forma habitual; no se modificará ningún aspecto de la misma. Se calculará la estadística descriptiva que incluyen la media y la desviación estándar (DE) para las variables continuas y las proporciones para los datos categóricos. Se realizará un análisis de sensibilidad, especificidad y valores predictivos. Resultados: Se incluyeron un total de 63 participantes, la edad promedio fue de 55 años, las mujeres fueron mayoría (34) representaron el 54%, 24.5% de los participantes tenían DM2, cumplieron el ayuno establecido 98.1%. El ultrasonido gástrico tuvo una sensibilidad para predecir un estómago vacío del 100% y una especificidad del 96%, además los valores predictivos positivos y negativos fueron de 83% y 100% respectivamente. Conclusión: se demostró que el ultrasonido gástrico es eficaz para predecir una cámara gástrica vacía antes de realizar una endoscopia. Se podría realizar en pacientes en los que se sospeche de que el estómago no este vacío, como por ejemplo, aquellos con un ayuno menor al establecido o con síntomas de obstrucción al vaciamiento gástrico, y así se evitaría tener que suspender el procedimiento y disminuiría el riesgo de aspiración

Contraste de un modelo de los determinantes de la estancia turística en la era covid-19: implicaciones para la bioseguridad

The reactivation of tourism had been studied by the influence of the habitus of movement and stay, but with the health contingency, this process was mediated by the information from the places with biosecurity protocols. The objective of the present work was to contrast a model of the determinants of stay, considering the mediating variables of the information. A confirmatory, psychometric, and cross-sectional study was carried out with a selection of 100 students from a public university in central Mexico. A factorial structure was found that explained 61% of the variance and established the intention to transfer as a predictor, suggesting the extension of the work towards biosafety protocols.La reactivación del turismo se había estudiado por la influencia del habitus de traslado y estancia, pero con la contingencia sanitaria este proceso estuvo mediatizado por la información de los lugares con protocolos de bioseguridad. El objetivo del presente trabajo fue contrastar un modelo de los determinantes de la estancia, considerando las variables mediadoras de la información. Una confirmación, psicométrico y estudio transversal se llevó a cabo con una selección de 100 estudiantes de una universidad pública en el centro de México. Se encontró una estructura factorial que explicaba el 61% de la varianza y estableció la intención de transferir como predictor, sugiriendo la extensión del trabajo hacia protocolos de bioseguridad.&nbsp

West Nile Virus Survey of Birds, Horses, and Mosquitoes of the Pacific Coast, Southern Mexico

Abstract. Serology of West Nile virus vectors and non-human reservoirs was surveyed at Acapulco, Jose Azueta, and Ometepec, three Pacific Coast localities of Guerrero State, Mexico. The objectives of this study were to use enzyme-linked immnosorbent assay (ELISA) to assess West Nile virus antibodies of bird and equine serum samples and use reverse transcription of polymerase chain reaction (RT-PCR) to detect the virus in field-collected resting mosquitoes. Forty birds trapped using mist nets yielded 10% seroprevalence. Similarly, 18.6% of 102 equine blood samples had West Nile virus. In addition, 4,854 mosquitoes were caught using motorized backpack aspirators and grouped into 116 pools. Of the 16 species and seven genera, no mosquito was positive for West Nile virus. Our study demonstrated West Nile virus seroprevalence on resident birds and equines in Guerrero State, Mexico

Incorporating Breast Asymmetry Studies into CADx Systems

Breast cancer is one of the global leading causes of death among women, and an early detection is of uttermost importance to reduce mortality rates. Screening mammograms, in which radiologists rely only on their eyesight, are one of the most used early detection methods. However, characteristics, such as the asymmetry between breasts, a feature that could be very difficult to visually quantize, is key to breast cancer detection. Due to the highly heterogeneous and deformable structure of the breast itself, incorporating asymmetry measurements into an automated detection system is still a challenge. In this study, we proposed the use of a bilateral registration algorithm as an effective way to automatically measure mirror asymmetry. Furthermore, this information was fed to a machine learning algorithm to improve the accuracy of the model. In this study, 449 subjects (197 with calcifications, 207 with masses, and 45 healthy subjects) from a public database were used to train and evaluate the proposed methodology. Using this procedure, we were able to independently identify subjects with calcifications (accuracy = 0.825, AUC = 0.882) and masses (accuracy = 0.698, AUC = 0.807) from healthy subjects

First results of the CAST-RADES haloscope search for axions at 34.67 μeV

We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in the 34.67μeV mass range. A radio frequency cavity consisting of 5 sub-cavities coupled by inductive irises took physics data inside the CAST dipole magnet for the first time using this filter-like haloscope geometry. An exclusion limit with a 95% credibility level on the axion-photon coupling constant of gaγ & 4 × 10−13 GeV−1 over a mass range of 34.6738μeV < ma < 34.6771μeV is set. This constitutes a significant improvement over the current strongest limit set by CAST at this mass and is at the same time one of the most sensitive direct searches for an axion dark matter candidate above the mass of 25μeV. The results also demonstrate the feasibility of exploring a wider mass range around the value probed by CAST-RADES in this work using similar coherent resonant cavitiesWe wish to thank our colleagues at CERN, in particular Marc Thiebert from the coating lab, as well as the whole team of the CERN Central Cryogenic Laboratory for their support and advice in speci c aspects of the project.

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed
