Non-COVID-19 deaths in times of pandemic.

BACKGROUND AND OBJECTIVE: To investigate the effect of the COVID-19 pandemic on non-COVID-19 deaths in Mexico. METHODS: This study analyzes monthly administrative data on 15 different causes of death in Mexico from 2017 to 2020. The effects of the COVID-19 pandemic on non-COVID-19 deaths are conducted using a difference-in-differences methodology and an event study. RESULTS: The evidence shows mixed results. There is an increase in six causes of death: diabetes (36.8%), hypertension (25.8%), heart attacks (40.9%), bronchitis- asthma (24.2%), anemia (28.6%) and prostate cancer (21.4%). There is a decrease in two causes of death: traffic accidents (8.8%) and HIV (13.8%). There are null effects for seven causes of death: breast cancer, cerebrovascular disease, malnutrition, alcohol-related liver disease, renal insufficiency, homicides and suicides. CONCLUSIONS: The COVID-19 pandemic affected non-COVID-19 deaths caused by diseases that require intensive healthcare services. Conversely, this pandemic reduced social interactions, which contributed to a decrease on deaths such as traffic accidents.

High phylogeographic and genetic diversity of Tidestromia lanuginosa supports full-glacial refugia for arid-adapted plants in southern and central Coahuila, Mexico.

PREMISE: Recent phylogeographic work suggests the existence of latitudinal gradients in genetic diversity in northern Mexican plants, but very few studies have examined plants of the Chihuahuan Desert. Tidestromia lanuginosa is a morphologically variable annual species whose distribution includes the Chihuahuan Desert Region. Here we undertook phylogeographic analyses of chloroplast loci in this species to test whether genetic diversity and differentiation of Mexican populations of T. lanuginosa change along a latitudinal gradient and whether diversity is higher in Coahuila, consistent with ideas of lower plant community turnover during the Pleistocene. METHODS: Haplotype network, maximum likelihood tree, and Bayesian phylogenetic haplotype were reconstructed, and genetic diversity was assessed among 26 populations. Barrier analysis was used to explore barriers to gene flow. RESULTS: Four major population groups were identified, corresponding with physiographic provinces in Mexico. Each population group displayed high levels of genetic structure, haplotype, and nucleotide diversity. Diversity was highest in southern populations across the species as a whole and among the Chihuahuan Desert populations. CONCLUSIONS: Tidestromia lanuginosa provides an important example of high phylogeographic and genetic diversity in plants of northern Mexico. Barriers to gene flow among the major population groups have most likely been due to a combination of orographic, climatic, and edaphic variables. The high genetic diversity of T. lanuginosa in southern and central Coahuila is consistent with the hypothesis of full-glacial refugia for arid-adapted plants in this area, and highlights the importance of this region as a center of diversity for the Chihuahuan Desert flora.

Tecnologías de información para lucha anticorrupción: análisis de la contratación pública costarricense / Tecnologias da informação para a luta contra a corrupção: análise da contratação pública costarriquenha / Information technologies for countering corruption: analysis of the Costa Rican public procurement system

Resumen La corrupción es un fenómeno con consecuencias desastrosas para el bienestar económico, social y político de nuestras sociedades. En particular, la contratación pública es vulnerable debido al elevado valor económico de sus transacciones. La presente investigación analiza el rol que las tecnologías de información pueden jugar en la lucha anticorrupción. Desarrollamos un caso basado en datos abiertos de contrataciones públicas en Costa Rica, con la finalidad de identificar los conceptos principales asociados al sistema de información subyacente. El caso muestra el potencial de las herramientas tecnológicas de análisis de redes sociales para contrarrestar la complejidad de las redes de corrupción. Asimismo, se evidencia la necesidad de disponer de un ecosistema rico en datos anticorrupción, preferiblemente en formato abierto.

Resumo: A corrupção é um fenômeno com consequências desastrosas para o bem-estar econômico, social e político das nossas sociedades. Em particular, a contratação pública é um fator altamente vulnerável devido ao alto valor econômico de suas transações. A pesquisa analisa o papel que as tecnologias da informação podem desempenhar no combate à corrupção. Além disso, desenvolvemos um caso baseado em dados abertos sobre compras públicas na Costa Rica, a fim de identificar os principais conceitos associados ao sistema de informação subjacente. O caso mostra o potencial das ferramentas tecnológicas de análise de redes sociais para ir de encontro a complexidade das redes de corrupção. Mostra também a necessidade de um ecossistema diversificado e sustentável de dados anticorrupção - preferencialmente em formato aberto.

Abstract Corruption has disastrous consequences for the well-being of societies. In particular, public procurement is a highly vulnerable factor due to the high value of its transactions. This research analyzes the role that information technologies can play in the fight against corruption. We developed a case based on open data on public procurement in Costa Rica to identify the main concepts associated with the underlying information system. The case shows the potential of technological tools for social network analysis to counter the complexity of corruption networks. It also shows the need for a rich ecosystem of anti-corruption data - preferably in an open format.

[Integral bread development with soybean, chia, linseed, and folic acid as a functional food for women]. / Desarrollo de pan integral con soya, chía, linaza y ácido fólico como alimento funcional para la mujer.

Six bread formulations were developed, using different proportions of whole-wheat flour, chia seeds and flaxseed flour. All of our formulations were added with folic acid. Sensorial and texture evaluations were performed, showing good acceptance of the products. Proximal chemical analysis was carried out; in addition, the following parameters were determined: calcium, phosphorus, total dietary fiber, folic acid, water hydration capacity, Glucose Dialysis Retardation Index (GDRI) and fatty acids. The results obtained showed higher protein levels in the developed breads (23.23-30.24 (g/100g dry matter) as compared to a control (21.00% of proteins in bread elaborated without chia or flaxseed). Furthermore, the breads contained 10.07-12.15 of lipids (g/100g dry matter) (linoleic acid: 2.43-4.05%; linolenic acid: 1.12-4.46 %; oleic acid: 2.93-6.13 %), GDRI values were between 89.1 and 98.1 % and folic acid was in the range 699.44 - 991.3 (microg/100g dry matter). The same parameters were determined in the chia seed and in the flaxseed flour. It was concluded that; due to their high levels of protein, insaturated fatty acids (omega-3 and omega-6), dietary fiber and folic acid, these breads have a high nutritional value, so they could have special benefits for woman.
