Many long for a return to a post-pandemic "normal," which, for some, may entail concerts, travel, and large gatherings. But how to keep safe amid these potential public health risks?

One possibility, according to a new study, is dogs. A proof-of-concept investigation published today in the journal PLOS ONE suggests that specially trained detection dogs can sniff out COVID-19-positive samples with 96% accuracy.

DALLAS, April 15, 2021 - Maintenance of good oral health is more important than use of antibiotics in dental procedures for some heart patients to prevent a heart infection caused by bacteria around the teeth, according to a new American Heart Association (AHA) scientific statement published today in the association's flagship journal, Circulation.

BOSTON - Approximately one in four patients hospitalized for the acute respiratory distress syndrome (ARDS) associated with severe COVID-19 infections may have a distinct phenotype (disease presentation) or biochemical profile associated with organ dysfunction, blood-clotting abnormalities and greater risk of death than patients with other, seemingly similar forms of the disease, researchers at Massachusetts General Hospital (MGH) have found.

Sophia Antipolis - 15 April 2021: An observational study in nearly 20,000 individuals has found that greater intake of red and processed meat is associated with worse heart function. The research is presented at ESC Preventive Cardiology 2021, an online scientific congress of the European Society of Cardiology (ESC).1

A technique called percutaneous peripheral nerve stimulation yields "impressive" reductions in pain scores and opioid use during the first week after common orthopedic surgery procedures, concludes a randomized clinical trial published Online First in Anesthesiology, the official peer-reviewed journal of the American Society of Anesthesiologists (ASA), today.

The COVID-19 disease due to infection by the SARS-CoV2 virus has changed the behavior patterns of humanity by becoming a pandemic of international scope. To date, more than 136 million people have suffered from the disease and more than 2.9 million of them have lost their lives. It is important to remember that the symptoms of the infection vary widely in the population, from individuals who do not present any symptoms to those who need admission to intensive care units with emergency assisted ventilation.

Key takeaways

Pancreatic, liver, bile duct, and stomach cancer operations are inherently complex and initially often take place at large cancer centers where surgical teams perform a large volume of procedures.
Readmission to a different hospital from where patients had these operations initially performed markedly increases death risk.
There are ways to address care fragmentation with newly identified risk factors for readmission; cancer hospitals should seek to determine safe sites of care for readmissions after these types of operations.

Hamilton, ON (April 14, 2021) - Modified immune cells that ruthlessly kill cancerous tumours may prove a game-changer for people living with late-stage cancer.

McMaster University researchers Ali Ashkar and Sophie Poznanski have uncovered that changing the metabolism of natural killer (NK) immune cells allows these cells to overcome the hostile conditions found inside tumours and destroy advanced ovarian and lung cancer.

Leesburg, VA, April 15, 2021--A Scientific E-Poster to be presented at the 2021 ARRS Virtual Annual Meeting found that in the setting of a high pretest probability of COVID-19 infection or with a quick turnaround of the rapid real-time reverse transcriptase-polymerase chain reaction (RT-PCR) COVID-19 test, a chest x-ray (CXR) scoring system may be used prospectively to predict patient outcomes.

Researchers in the Department of Neurology at Tohoku University, which is led by professor Masashi Aoki, have developed a classification scheme for neuromyelitis optica spectrum disorder, a rare autoimmune disease that until recently was thought to be a type of multiple sclerosis (MS). The new taxonomy for the disease replaces one borrowed from MS but which was inappropriate for what is in fact a distinct condition.

Patients who are overweight or obese have more severe COVID-19 and are highly likely to require invasive respiratory support, according to a new international study.

The research, led by the Murdoch Children's Research Institute (MCRI) and The University of Queensland and published in Diabetes Care, found obese or overweight patients are at high risk for having worse COVID-19 outcomes. They are also more likely to require oxygen and invasive mechanical ventilation compared to those with a healthy weight.

Guangzhou, April 8, 2021: New journal BIO Integration (BIOI) publishes its fifth issue, volume 2, issue 1. BIOI is a peer-reviewed, open access, international journal, which is dedicated to spreading multidisciplinary views driving the advancement of modern medicine.

The inner surface of blood vessels is lined by a wafer-thin layer of cells known as the endothelium, which forms a crucial barrier between blood and the surrounding tissue. The single-layered cell structure promotes the exchange of oxygen and nutrients, while simultaneously preventing the uncontrolled leakage of blood components. Only when the metabolic needs of the surrounding tissue increase, e.g., during growth, wound healing or tumor development, do endothelial cells abandon this stable cell association in order to divide and form new blood vessels.

Detecting hidden genetic defects by applying an existing method to an existing datasets. Researchers at Radboud university medical center have succeeded: they showed that the 'Expansion Hunter' method can detect errors in the DNA that lead to repeat expansion diseases, such as the movement disorder ataxia. This result provides guidance to fellow researchers worldwide on how to use this method to diagnose patients with genetic disorders.
