(Press-News.org) WASHINGTON, D.C., (April 28, 2021) - The latest, comprehensive data from The North American COVID-19 Myocardial Infarction (NACMI) Registry was presented today as late-breaking clinical research at the Society for Cardiovascular Angiography & Interventions (SCAI) 2021 Scientific Sessions. Results reveal in these series of STEMI activations during the COVID era, patients who tested positive for COVID-19 were less likely to receive diagnostic angiograms. Those with COVID-19 positive status had higher in-hospital mortality. The prospective, ongoing observational registry was created under the guidance of the SCAI, Canadian Association of Interventional Cardiology (CAIC) and American College of Cardiology (ACC). The initial results of the registry were published in the Journal for American College of Cardiology (JACC) on April 27, 2021.
According to the American Heart Association, more than 930,000 people suffer from heart attacks every year and more than a quarter of those patients suffer the more severe type of heart attack, an ST-elevated myocardial infarction, or STEMI caused by the sudden, total blockage of a coronary artery. Qualifying patients often undergo a (percutaneous coronary intervention (PCI), a nonsurgical, angiography procedure that improves blood flow to the heart. However, little is known on how the ongoing COVID-19 pandemic impacted the use of angiography procedures based on patient demographics and outcomes.
As of April 9, 2021, more than 1,600 patients were included in the NACMI (331 STEMI with were COVID-19, 645 suspected COVID-19 positive patients and 662 control - a group of age and sex matched STEMI patients treated pre-COVID-19). The primary outcome was a composite of in-hospital death, stroke, recurrent myocardial infarction or repeat unplanned revascularization. The overall goal of the registry is to understand demographic characteristics, management strategies and outcomes of COVID-19 patients with STEMI.
Findings show COVID-19 positive patients were more likely to be of minority ethnicity, have diabetes and undergo medical therapy as a first-line treatment rather than PCI (all p END

Late-breaking studies highlight new treatment protocols for cardiogenic shock patients
2021-04-28
WASHINGTON, D.C., (April 28, 2021) - Two new studies, presented today as late-breaking clinical science at the Society for Cardiovascular Angiography & Interventions (SCAI) 2021 Scientific Sessions, provide new treatment insights for cardiogenic shock (CS) patients. A study of the SCAI cardiogenic shock stages consensus document confirms the accuracy of the shock classification. In addition, an analysis of the National Cardiogenic Shock Initiative demonstrates use of a shock protocol emphasizing early use of mechanical circulatory support may lead to improved survival for patients with CS.
CS is a rare, life-threatening ...
Study reinforces benefits of long-term duel antiplatelet therapy for ACS patients
2021-04-28
WASHINGTON, D.C, (April 28, 2021) - An analysis of the prospective Fuwai PCI Registry, confirms long-term dual antiplatelet therapy (DAPT) is an optimal treatment option for acute coronary syndrome patients (ACS) following a percutaneous coronary intervention (PCI). The study shows long-term DAPT reduces ischemic events without increasing bleeding or other complications as compared to short-term DAPT treatments. The study was presented today as late-breaking clinical research at the Society for Cardiovascular Angiography &Interventions (SCAI) 2021 Scientific Sessions.
Following ACS, patients have a high risk of ischemic events, which impacts chances of survival. Patients are predisposed for blood clots ...
Scientists see chemical short-range order in medium-entropy alloy
2021-04-28
Chinese scientists have made direct observations in face-centered cubic VCoNi (medium)-entropy alloys (MEA) and for the first time proposed a convincing identification of subnanoscale chemical short-range order (CSRO). This achievement undisputedly resolves the pressing question of if, what and why CSRO exists, and how to explicitly identify CSRO.
This work, published in Nature on April 29, was conducted by Prof. WU Xiaolei from the Institute of Mechanics of the Chinese Academy of Sciences (CAS) in collaboration with Prof. MA En's team from Xi'an Jiaotong University and Prof. ZHU Jing's team from Tsinghua University.
Multi-principal element alloys--also known as high (medium)-entropy alloys (HEAs/MEAs)--are a hot and frontier topic in multidisciplinary fields. In these ...
Proposal of new universal nomenclature for oxytocin and vasotocin genes
2021-04-28
Oxytocin and arginine vasopressin are two hormones in the endocrine system that can act as neurotransmitters and regulate -in vertebrates and invertebrates- a wide range of biological functions, such as bonding formation, breastfeeding, birth or arterial pressure. Biochemists in the pregenomic era, named these genes differently in different species, due to small protein coding differences.
A new study carried out by the University of Barcelona (UB) and the Rockefeller University, published in the journal Nature, has analysed and compared the genome of 35 species representing ...
Cancer-linked mutation accelerates growth of abnormal stroke-causing brain blood vessels
2021-04-28
Researchers have discovered an explanation for why cerebral cavernous malformations (CCMs)--clusters of dilated blood vessels in the brain--can suddenly grow to cause seizures or stroke. Specifically, they found that a specific, acquired mutation in a cancer-causing gene (PIK3CA) could exacerbate existing CCMs in the brain. Furthermore, repurposing an already existing anticancer drug showed promise in mouse models of CCMs in improving brain-vascular health and preventing bleeding into the brain tissue.
Previous studies linked the initial formation of CCMs to various environmental factors, including ...
How acidic are atoms?
2021-04-28
The degree of acidity or alkalinity of a substance is crucial for its chemical behavior. The decisive factor is the so-called proton affinity, which indicates how easily an entity accepts or releases a single proton. While it is easy to measure this for molecules, it has not been possible for surfaces. This is important because atoms on surfaces have very different proton affinities, depending on where they sit.
Researchers at TU Wien have now succeeded in making this important physical quantity experimentally accessible for the first time: Using a specially modified atomic force microscope, it is possible to study the proton affinity of individual atoms. This should help to analyze catalysts on an atomic scale. The results have been published in the scientific journal Nature.

Using nanobodies to block a tick-borne bacterial infection
2021-04-28
COLUMBUS, Ohio - Tiny molecules called nanobodies, which can be designed to mimic antibody structures and functions, may be the key to blocking a tick-borne bacterial infection that remains out of reach of almost all antibiotics, new research suggests.
The infection is called human monocytic ehrlichiosis, and is one of the most prevalent and potentially life-threatening tick-borne diseases in the United States. The disease initially causes flu-like symptoms common to many illnesses, and in rare cases can be fatal if left untreated.
Most antibiotics can't build up ...
Processed diets might promote chronic infections that can lead to disorders such as diabetes
2021-04-28
ATLANTA--Processed diets, which are low in fiber, may initially reduce the incidence of foodborne infectious diseases such as E. coli infections, but might also increase the incidence of diseases characterized by low-grade chronic infection and inflammation such as diabetes, according to researchers in the Institute for Biomedical Sciences at Georgia State University.
This study used mice to investigate how changing from a grain-based diet to a highly processed, high-fat Western style diet impacts infection with the pathogen Citrobacter rodentium, which resembles Escherichia coli (E. coli) infections in humans. The findings are published in the journal PLOS Pathogens.
Gut microbiota, the microorganisms living in the intestine, provide a number of benefits, ...

2021-04-28
The scientific community is focusing its research into the multiple applications of Hydrogels, polymeric materials which contains a large amount of water, that have the potential to reproduce the features of biological tissues. This aspect is particularly significant in the field of regenerative medicine, which since a long time has already recognised and been using the characteristics of these materials. In order to be used effectively to replace organic tissues, hydrogels must meet two essential requirements: possessing great geometric complexity and, after suffering of a damage, being ...
Virtual reality could help improve balance in older people
2021-04-28
Researchers at the University of Bath investigating how virtual reality (VR) can help improve balance believe this technology could be a valuable tool in the prevention of falls.
As people grow older, losing balance and falling becomes more common, which increases the risk of injury and affects the person's independence.
Falls are the leading cause of non-fatal injuries in over 65-yearolds and account for over 4 million bed days per year in England alone, at an estimated cost of £2 billion.
Humans use three ways of keeping their balance: vision, proprioceptive (physical feedback from muscles and joints) and vestibular system (feedback from semi-circular canals in the ear). Of these, vision is the most important.
Traditional ways of assessing balance ...
