Eight strains of coronavirus afflicting the world

Tue, 03/31/2020 - 12:18
Scientists around the world are racing to study the novel coronavirus strain severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Now, it appears that there are eight strains of SARS-CoV-2 circulating the globe. The good news is that according to infectious disease physician and clinical microbiologist Charles Chiu, “The virus mutates so slowly that the virus strains are fundamentally very similar to each other.”

Ticagrelor therapy, without aspirin, can benefit patients with acute coronary syndrome

Tue, 03/31/2020 - 12:02
Patients with acute coronary syndrome (ACS) who stopped taking aspirin three months after the insertion of a coronary stent and then took the anti-platelet medication ticagrelor alone for nine months had fewer episodes of bleeding and no increase in heart attacks, stroke or other adverse events caused by blockages in the arteries, compared with patients who took both aspirin and ticagrelor for a year.

Why do men stop treatment for erectile dysfunction?

Tue, 03/31/2020 - 11:55
A new study published in the journal IJIR: Your Sexual Medicine Journal in March 2020 reports the most common reasons why men stop their treatment for erectile dysfunction. The most common reasons were that the treatment did not work, cost too much, or had unacceptable side effects. Loss of interest in sexual relationships was another primary reason.

Clopidogrel added to aspirin and rvaroxaban shows no additional benefit for peripheral artery disease

Tue, 03/31/2020 - 11:28
The results of VOYAGER PAD found that people with peripheral artery disease (PAD) who took the blood thinner rivaroxaban with aspirin after undergoing lower extremity revascularization--a procedure to treat blocked arteries in the leg--had a significant reduction in the risk of major adverse limb and cardiovascular events when compared with those receiving aspirin alone.

First-of-its-kind trial identifies a viable target for treating anhedonia

Tue, 03/31/2020 - 10:42
A first-of-its-kind trial has demonstrated that a receptor involved in the brain's reward system may be a viable target for treating anhedonia (or lack of pleasure), a key symptom of several mood and anxiety disorders.

UDCA treatment affects C. diff life cycle, reduces inflammatory response in mice

Tue, 03/31/2020 - 08:52
Researchers from North Carolina State University have found that a commonly used drug made from secondary bile acids can affect the life cycle of Clostridioides difficile (C. diff) in vitro and reduce the inflammatory response to C. diff in mice.

Vaping with counseling more effective than counseling alone for smoking cessation

Tue, 03/31/2020 - 08:44
Smokers who received smoking cessation counseling and used electronic cigarettes containing nicotine were more than twice as likely to successfully quit smoking compared to those who received counseling but did not use e-cigarettes, in a clinical trial presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

UMass Amherst study explores effects ER caregivers’ on-the-job emotions on patient care

Tue, 03/31/2020 - 08:34
Doctors and nurses in emergency departments at four academic centers and four community hospitals in the Northeast reported a wide range of emotions triggered by patients, hospital resources and societal factors, according to a qualitative study led by a University of Massachusetts Amherst social psychologist.

Higher serum EPA levels from prescription fish oil associated with lower cardiovascular events

Tue, 03/31/2020 - 08:22
Higher levels of the omega-3 fatty acid eicosapentaenoic acid (EPA) found in the blood—and not a decrease in triglyceride levels as originally thought—appear to explain the striking reductions in cardiovascular events and deaths seen among people taking 4 grams daily of the prescription fish oil, icosapent ethyl, according to findings from a REDUCE-IT substudy presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology

Patients with chest pain, abnormal stress test results need attention even if arteries are clear

Tue, 03/31/2020 - 08:15
Patients who experience chest pain and have abnormal results on a cardiac stress test but who do not have blocked arteries often experience changes in their symptoms and stress test results over time, according to research presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

Clinical trial using genetic testing to guide antiplatelet therapy post-PCI falls short of stated goal

Tue, 03/31/2020 - 08:03
An international clinical trial that used genetic testing to guide which antiplatelet medication was given to patients following percutaneous coronary intervention (PCI) did not meet its stated goal for cutting in half the incidence of serious adverse cardiovascular events, such as heart attack and stroke, in the year following the procedure.

Origins of SARS-CoV-2 – natural or man-made?

Tue, 03/31/2020 - 07:36
With over 780,000 individuals across the world infected and over 37,000 dead, the world is gripped by the pandemic caused by the novel strain of coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

New blood test accurately detects more than 50 types of cancer

Tue, 03/31/2020 - 07:03
Researchers have developed a blood test that could accurately detect up to 50 types of cancers, and some of these detections could be even before the symptoms appear. The test would help physicians detect the origin or the source of cancer within the body explain the researchers from the European Society of Oncology. The study titled, "Sensitive and specific multi-cancer detection and localization using methylation signatures in cell-free DNA," was published in the latest issue of the journal Annals of Oncology.

Coronavirus shown to spread in high heat and humidity

Tue, 03/31/2020 - 05:54
A new study explores the possibility that the novel coronavirus, which is ravaging the world, can spread in hot and humid conditions, dispelling the view held by some investigators that the virus is more easily transmissible in colder climates.
