People with heart rhythm disorders warned over cannabis use

2021-04-23
(Press-News.org) Sophia Antipolis - 23 April 2021: A study of 2.4 million hospitalised cannabis users has found that those with an arrhythmia were 4.5 times more likely to die while in hospital than those without. The research is presented at EHRA 2021, an online scientific congress of the European Society of Cardiology (ESC).1

"People should be aware of this devastating outcome and be careful when using cannabis if they have a concomitant heart problem," said study author Dr. Sittinun Thangjui of Bassett Healthcare Network, Cooperstown, US.

Marijuana or cannabis is the most commonly used psychoactive substance worldwide.2 However, there is limited knowledge about safety of the drug in people with cardiac arrhythmias. This study examined the burden of arrhythmias in drug users admitted to hospital. It also compared length of hospital stay and deaths in hospital between those with and without an arrhythmia.

The study was conducted using the National Inpatient Sample database, which covers 97% of the US population. The study included 2,457,544 adult cannabis users admitted to hospital in 2016 to 2018. Of those, 187,825 (7.6%) patients had an arrhythmia. Atrial fibrillation was the most common, followed by abnormally slow heart rate and abnormally fast heart rate.

Patients in arrhythmia group were older: the average age was 50.5 years compared to 38.3 years for those without an arrhythmia. Those with arrhythmias also had more co-existing health conditions.

The researchers compared deaths between the two groups after adjusting for factors that could influence the relationship including age, sex, race, income, diabetes, heart failure, chronic kidney disease, obesity, and hospital location. Cannabis users with an arrhythmia had a 4.5 times higher odds of in-hospital mortality compared to those without an arrhythmia. Patients with an arrhythmia had a longer length of hospital stay (5.7 days) compared to those without (5.1 days).

Dr. Thangjui said: "Our study highlights that heart rhythm disorders may be a warning sign for an increased risk of death in people who use cannabis. More studies are needed to confirm our results. In the meantime, it seems sensible to screen these patients for arrhythmias if they present to hospital so that those with a heart rhythm problem can be closely monitored."

Patching up your health

Patching up your health
2021-04-23
Osaka, Japan - Scientists at Osaka University, in cooperation with JOANNEUM RESEARCH (Weiz, Austria), introduced wireless health monitoring patches that use embedded piezoelectric nanogenerators to power themselves with harvested biomechanical energy. This work may lead to new autonomous health sensors as well as battery-less wearable electronic devices. As wearable technology and smart sensors become increasingly popular, the problem of providing power to all of these devices become more relevant. While the energy requirements of each component may be modest, the need for wires or even batteries become burdensome and inconvenient. That is why new energy harvesting methods are needed. Also, the ability ...

With new optical device, engineers can fine tune the color of light

2021-04-23
Among the first lessons any grade school science student learns is that white light is not white at all, but rather a composite of many photons, those little droplets of energy that make up light, from every color of the rainbow - red, orange, yellow, green, blue, indigo, violet. Now, researchers at Stanford University have developed an optical device that allows engineers to change and fine-tune the frequencies of each individual photon in a stream of light to virtually any mixture of colors they want. The result, published April 23 in Nature Communication, is a new photonic architecture that could transform fields ranging from digital communications and artificial intelligence to cutting-edge quantum computing. "This powerful new tool puts a degree of control in the engineer's ...

Quantum steering for more precise measurements

2021-04-23
Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles. In quantum information, the fictitious agents Alice and Bob are often used to illustrate complex communication tasks. In one such process, Alice can use entangled quantum particles such as photons to transmit or "teleport" a quantum state - unknown even to herself - to Bob, something that is not feasible using traditional communications. However, it has been unclear whether the team Alice-Bob can use similar quantum states for other things besides communication. A young physicist at the University ...

3D motion tracking system could streamline vision for autonomous tech

They're believed to be the first of their kind. "The ...

Climate-friendly microbes chomp dead plants without releasing heat-trapping methane

Climate-friendly microbes chomp dead plants without releasing heat-trapping methane
2021-04-23
The tree of life just got a little bigger: A team of scientists from the U.S. and China has identified an entirely new group of microbes quietly living in hot springs, geothermal systems and hydrothermal sediments around the world. The microbes appear to be playing an important role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane. "Climate scientists should take these new microbes into account in their models to more accurately understand how they will impact climate change," said END ...

New blood markers may reveal heart attack in chest pain patients

2021-04-23
A patient arrives at hospital with chest pain. Doctors suspect heart attack and rapid diagnosis is important, but the tests to confirm it can be invasive and it could easily be something else. Could a simple blood test help to non-invasively rule heart attack in or out? A new study in open access journal Frontiers in Cardiovascular Medicine certainly suggests so. The study identified telltale markers in the blood of heart attack patients that distinguished them from patients suffering chest pain with other causes. The researchers hope that the results will lead to new diagnostic tests for heart attacks. If you have ever suffered chest pain, the possibility of a heart attack may have popped into your head. While chest pain is ...

Study uncovers human-to-cat transmission of the virus that causes COVID-19

2021-04-23
New research provides evidence that people have transmitted SARS-CoV-2, the virus that causes COVID-19, to cats during the pandemic in the UK. The study, which is published in Veterinary Record, detected the virus last year in cats that developed mild or severe respiratory disease. Investigators used a range of laboratory techniques to show that two domestic cats from households with suspected cases of COVID-19 were infected with SARS-CoV-2. "These findings indicate that human-to-cat transmission of SARS-CoV-2 occurred during the COVID-19 pandemic in ...

Malaria vaccine becomes first to achieve WHO-specified 75% efficacy goal

2021-04-23
Researchers from the University of Oxford and their partners have today reported findings from a Phase IIb trial of a candidate malaria vaccine, R21/Matrix-M, which demonstrated high-level efficacy of 77% over 12-months of follow-up. In their findings (posted on SSRN/Preprints with The Lancet) they note that they are the first to meet the World Health Organization's Malaria Vaccine Technology Roadmap goal of a vaccine with at least 75% efficacy. The authors report (in findings in press with The Lancet) from a Phase IIb randomised, controlled, double-blind trial conducted at the Clinical Research Unit of Nanoro (CRUN) / Institut de Recherche en Sciences de la Santé (IRSS), Burkina Faso. 450 participants, aged 5-17 months, were recruited from the catchment area of Nanoro, covering ...

Radar satellites can better protect against bushfires and floods

2021-04-23
New research led by Curtin University has revealed how radar satellites can improve the ability to detect, monitor, prepare for and withstand natural disasters in Australia including bushfires, floods and earthquakes. The research used Synthetic Aperture Radar data obtained by the European Space Agency Sentinel-1 satellite, amongst others, to evaluate Australia-specific case studies. Lead researcher Dr Amy Parker, an ARC Research Fellow from Curtin's School of Earth and Planetary Sciences, said the Sentinel-1 satellite mission provided the first complete global Synthetic Aperture Radar (SAR) dataset and the first opportunity to use this type of data to assess hazards in new locations, including Australia. "What makes SAR so valuable is that it provides all-weather and night-and-day ...
