This situation has made the National Association of Cardiologists of Mexico (ANCAM) and the Mexican Society of Cardiology (SMC) together with their respective chapters, have prepared the following recommendations for medical personnel, who participate in the care of this special group of patients in the different clinical settings, who suffer or not, of COVID-19.The recommendations in which the Mexican Society of Cardiology (SMC) in conjunction with the National Association of Cardiologists of Mexico (ANCAM) as well as different Mexican medical associations linked to cardiology are presented, after a comprehensive and consensual review and analysis of the topics related to cardiovascular diseases in the COVID-19 pandemic. Scientific positions are analyzed and responsible recommendations on general measures are given to patients, with personal care, healthy eating, regular physical activity, actions in case of cardio-respiratory arrest, protection of the patient and health personnel as well as precise indications in the use of non-invasive cardiovascular imaging, prescription of medications, care in specific topics such as systemic arterial hypertension, heart failure, arrhythmias and acute coronary syndromes, in addition to emphasizing electrophysiology, interventionism, cardiac surgery and in cardiac rehabilitation. The main interest is to provide the medical community with a general orientation on what to do in daily practice and patients with cardiovascular diseases in the setting of this unprecedented epidemiological crisis of COVID-19.The Coronavirus pandemic (COVID-19) is one of the most devastating in this century. It originated in China in December 2019 caused by the SARS-Cov-2 virus, and in less than a month it had been classified as an "International Public Health Emergency". To date there are nearly 3 million people infected and more than 250,000 deaths caused by the disease worldwide. Initially it affects the respiratory tract with atypical pneumonia and in severe cases it produces systemic inflammation with cytokine storm that can cause rapid deterioration with circulatory and respiratory failure, coagulopathy and a lethality rate of approximately 7%. In Mexico, the first case was detected in February 2020, and to date there are 26,616 confirmed cases and 2,961 deaths throughout the country. https://www.selleckchem.com/products/elsubrutinib.html The low number of diagnostic tests conducted in our country clearly underestimates the real incidence and impact of the disease. The most affected groups are those with risk factors such as age over 60, presence of hypertension, diabetes or cardiovascular disease. Of the confirmed cases, 15% are healthcare workers. There is no specific treatment or vaccine yet, so it is important to have hygiene, social isolation and personal protection measures. Health, social and economic consequences could have great impact in the near future.Reperfusion therapy is a measure of care in patients with ST-elevation myocardial infarction (STEMI), which should be performed once we have the diagnosis. Percutaneous coronary intervention is considered the gold standard, however in patients with SARS-CoV-2 infection, the reperfusion strategy is more focused on fibrinolytic therapy due to the shorter time required to perform and less exposure. This pandemic represents a contact problem in health personnel, since cases are increasing worldwide, so it is important to know the measures that must be followed to avoid coronavirus disease (COVID-19).The communications accumulated in the last weeks make it clear that there is no agreement to define the best treatment strategy in patients with acute coronary syndrome (SICA). In patients presenting with an acute myocardial infarction with ST-segment elevation (IAMCESST), it has been suggested to favor fibrinolysis (FL) over primary percutaneous coronary intervention (PCI), reserving ICP for cases of failed FL1,2; however, some societies have maintained the indication of the ICPp as the repercussion method of choice3. In SICAs without ST segment elevation (SICASESST) the recommendations are very similar, favoring medical treatment over percutaneous coronary intervention in this subgroup of patients1. Several companies consider the contagion status, particularly in the SICASESST, to decide which repercussion follow3. Anticipating that the epidemiological curve in Mexico will be similar to that observed in most countries, we recommend continuing the care of patients with SICA, the catheterization rooms must maintain their operation.Background People with trisomy 21 (T21) are predisposed to developing hematological tumors, but have significantly lower-than-expected age-adjusted incidence rates of having a solid tumor. Material and methods To identify novel genetic factors implicated in the lower breast cancer (BC) frequency observed in women with T21 than in the general population, we compared the transcriptome pattern of women with a homogeneous T21, aged more than 30 years, with or without BC, and tumoral BC tissue of control women with a normal karyotype from the study of Varley et al. (2014). Results Differential analysis of gene expression between the 15 women in the T21 without BC group and BC patients in the other groups (two women with T21 and fifteen control women, respectively) revealed 154 differentially expressed genes, of which 63 were found to have similar expression profile (up- or downregulated). Of those 63 genes, four were in the same family, namely GIMAP4, GIMAP6, GIMAP7 and GIMAP8, and were strongly upregulated in the T21 without BC group compared to the other groups. A significant decrease in mRNA levels of these genes in BC tissues compared to non-tumor breast tissues was also noted. Conclusion We found that the expression of some GIMAPs is significantly higher in women with T21 without BC than in patients with sporadic BC. Our findings support the hypothesis that GIMAPs may play a tumor-suppressive role against BC, and open the possibility that they may also have the same role for other solid tumors in T21 patients. The search for new prognostic factors and hopefully new therapeutic or preventive strategies against BC are discussed.
