Coronavirus illness 2019 (COVID-19) is an airways infection caused by the new coronavirus (SARS-CoV-2) which has been quickly disseminated all over the world, affecting to the general population including women in pregnancy time. As being a recent infection, the evidence that supports the best practices for the management of the infection during pregnancy is limited, and most of the questions have not been completely solved yet.
This publication offers general guidelines focused on decision-making people, managers, and health’s teams related to pregnant women attention and newborn babies during COVID-19 pandemic. Its purpose is to promote useful interventions to prevent new infections as well as prompt and adequate attention to avoid serious complications or deaths, trying to be adapted to the different contexts in which attention to expectant mothers is provided. Guidelines are set within a well-scientific evidence and available recommendations up to date.
This paper aims to analyse the dynamic relationship between the stock market returns and exchange rates movements for the mila (Mercado Integrado Latinoamericano) countries: Colombia, Chile, México and Peru, over the period 01:2003 to 09:2016. Univariate (Markov Switching-Autoregressive) and multivariate (Markov Switching-Vector Autoregressive) regime-switching models approach are used. The univariate analysis offers evidence indicating that stock returns of the mila countries evolve according to two different regimes: a low volatility regime and a high volatility regime. The Markov Switching Vector Autoregressive models point out that stock markets have more influence on exchange rate than exchange rate has on stock markets. Results for the Peruvian and Chilean markets contribute evidence about contagion between the stock and the exchange rate markets. * Profesora, Facultad de Economía. unam.
Introduction: Placenta accreta spectrum (PAS) is a serious condition with a mortality as high as 7%. However, the factors associated with this type of death have not been adequately described, with an almost complete lack of publications analyzing the determining factors of death in this disease. The aim of our work is to describe the causes of death related to PAS and to analyze the associated diagnosis and treatment problems. Material and methods: This is an inter-continental, multicenter, descriptive, retrospective study in low-and middle-income countries. Maternal deaths related to PAS between January 2015 and December 2020 were included. Crucial points in the management of PAS, including prenatal diagnosis and details of the surgical treatment and postoperative management, were evaluated. | 1453 NIETO-CALVACHE ET AL.
A substantial body of evidence documents the relationship between macroeconomic variables and stock returns and risk from developed countries. The evidence for emerging markets is limited, particularly identifying risk premia compensations for inflation and exchange rates. This paper attempts to quantify the short and long term relationship between inflation and exchange rates with over all stock market performance for the case of the two largest Latin American capital markets, Mexico and Brazil. Extending the Fisher model, the aim is to determine whether or not these markets have failed to keep pace with movements in those two variables (the most unstable and economic growth hampering variables in these economies during the last three decades), and therefore to what extent the stock market succeeds or fails to test as inflation hedges. The empirical evidence is presented assuming positioning of a local investor in their own market, and from the point of view of a U.S. investor in each of these markets. Two unit root tests are also presented to stress long term relationships between stock returns, inflation, and foreign exchange.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
