World Economic Forum: Top Stories- March 25, 2023

World Economic Forum (March 25, 2023) – This week’s top stories of the week include:


0:15 NASA launches space based pollution monitor – It’s called TEMPO, which stands for Tropospheric Emissions: Monitoring of Pollution. Built by Ball Aerospace, TEMPO will measure levels of major air pollutants every hour from a geostationary orbit 22,000 miles above the equator. It will monitor a huge region of North America from Canada’s oil sands in northern Alberta to below Mexico City at a resolution of up to 4 square miles. Air pollution poses a major threat to human and planetary health as 99% of the global population breathes air that exceeds WHO health guidelines. Air pollution carries a total economic cost of more than $8 trillion. Therefore, monitoring it is critical to understanding its impacts. Though TEMPO is due to launch in April 2023, watch to learn more about how it will monitor air pollution from space.

1:58 8 best countries for working women – The Economist ranked 29 OECD nations according to the role and influence of women in the workplace. Iceland scores well on numerous factors. From low childcare costs to education attainment for women to female representation at senior levels. At the current rate, it will take 132 years to close the global gender gap How does your country support women at work?

3:23 What is the polycrisis? – Today we are once again beset by seemingly unconnected crises. Such as the war in Ukraine, the climate crisis and the aftermath of COVID-19. “So economics, politics, geopolitics and then the natural environment blowing back at us – and those 4 things, they don’t reduce to a single common denominator. They don’t reduce to a single factor. And that’s why I think the polycrisis term has a real utility descriptively as much as anything else, because it’s kind of hand-waving, of course, it’s kind of arm waving. It’s going, look, there’s a lot of stuff happening here all at once. And that precisely is what we’re trying to wrap our minds around.”

6:54 Are Chatbots going to take our jobs? – “I get this question asked 10 times a week, which is that, look, is conversational AI going to take away jobs? And my consistent answer is no. And the best analogy I will give to you is banks and ATMs. So prior to the technology of ATMs, the most common reason why people would walk into a bank would be to take out money. So imagine there’s no ATMs and 90% of the reason why somebody goes inside the bank is to say, I need to take out some cash, I need to take out some money. As a result, you know, you and I don’t even remember these days, but banks used to be crowded. There used to be long lines and so on. Here comes the ATM, which automates really what should be a very simple task.”

World Economic Forum: Top Stories- March 18, 2023

World Economic Forum (March 18, 2023) – This week’s top stories of the week include:

0:15 Silicon Valley Bank collapse explained – On 10 March, Silicon Valley Bank (SVB) failed after a ‘run’ on the bank from customers wishing to draw cash. The bank didn’t have enough funds to pay them. So federal regulators had to step in and shut it down. Silicon Valley Bank is the biggest US bank to fail since the 2008 financial crisis and the second-biggest ever. Just a few days ago, it was a respected player in the tech space, with thousands of venture capital-backed start-ups among its customers. So how did things go wrong so quickly? Watch the video to learn more about the Silicon Valley Bank collapse.

2:14 Aviation will be net zero by 2050 – Altogether, aviation is currently responsible for 2.5% of global emissions. Without action to reduce emissions, demand could see this soar 300% by 2050. 65% of the way to net zero will come from switching to sustainable aviation fuels (SAF). Its production uses a fraction of the carbon footprint generated by petroleum fuel.

3:49 AI detects lung cancer better than humans – It reads routine chest X-rays to highlight up to 29 abnormalities. Including the patient’s risk of lung cancer so a radiologist can take a look. Usually, human radiologists scour X-rays by eye. But 20% of lung cancer risks go undetected this way, causing a potential delay in diagnosis and poorer outcomes. The new tool was developed by Qure.ai and is being scaled up in partnership with AstraZeneca. The tool was trained using over 4 million X-rays. In trials, it was 17% more sensitive than a human. Early data indicates impressive accuracy for identifying risk of malignancy

5:18 Researchers restore movement for stroke victims – Doctors implant electrodes in the patient’s neck. These stimulate undamaged parts of the spinal cord and bring movement back to paralyzed arms and hands.

Emergency Medicine: Use Of Flying Intervention Teams In Ischemic Stroke

In a nonrandomized controlled intervention study published in JAMA, researchers in Germany assessed whether deployment of a flying interventional team, consisting of a neurointerventional radiologist and an angiography assistant, was associated with a shorter time to endovascular thrombectomy for patients in rural or intermediate population areas in Southeast Bavaria.

Health: How ‘Statins’ Prevent Heart Attacks And Strokes’ (CDC Video)

Statins are a type of medication used to lower the level of bad cholesterol in the blood and reduce build-up in arteries that can cause a heart attack or stroke. This short animated video explains the importance of statins, how they work, and why your doctor may prescribe them.

Medicine: ‘Three Critical Breakthroughs In Stroke Research’ (Yale Video)

Stroke is far more common than you might realize, affecting more than 795,000 people in the U.S. every year. It is a leading cause of death and long-term disability. Yet until now, treatment options have been limited, despite the prevalence and severity of stroke.

Not so long ago, doctors didn’t have much more to offer stroke victims than empathy, says Kevin Sheth, MD, Division Chief of Neurocritical Care and Emergency Neurology. “There wasn’t much you could do.” But that is changing. Recent breakthroughs offer new hope to patients and families. Beating the Clock Think of stroke as a plumbing problem in the brain. It occurs when there is a disruption of blood flow, either because of a vessel blockage (ischemic stroke) or rupture (hemorrhagic stroke).

In both cases, the interruption of blood flow starves brain cells of oxygen, causing them to become damaged and die. Delivering medical interventions early after a stroke can mean the difference between a full recovery and significant disability or death. Time matters. Unfortunately, stroke care often bottlenecks in the first stage: diagnosis. Sometimes, it’s a logistical issue; to identify the type, size, and location of a stroke requires MRI imaging, and the machinery itself can be difficult to access.

MRIs use powerful magnets to create detailed images of the body, which means they must be kept in bunker-type rooms, typically located in hospital basements. As a result, there is often a delay in getting MRI scans for stroke patients. Dr. Sheth collaborated with a group of doctors and engineers to develop a portable MRI machine. Though it captures the images doctors need to properly diagnose stroke, it uses a less powerful magnet. It is lightweight and can be easily wheeled to a patient’s bedside.

“It’s a paradigm shift – from taking a sick patient to the MRI to taking an MRI to a sick patient,” says Dr. Sheth. Stopping the Damage Once a stroke has been diagnosed, the work of mitigating the damage can begin. “Brain tissue is very vulnerable during the first hours after stroke,” says vascular neurologist Nils Petersen, MD. He and his team are using advanced neuro-monitoring technology to study how to manage a patient’s blood pressure in the very acute phase after a stroke.

Dr. Petersen’s research shows that optimal stroke treatment depends on personalization of blood pressure parameters. But calculating the ideal blood pressure for the minutes and hours after a patient has a stroke can be complicated. It depends on a variety of factors—it is not a one-size-fits-all scenario. Harnessing the Immune System Launching an inflammatory reaction is how the body responds to injury anywhere in the body – including the brain, following stroke. However, in this case, the resulting inflammation can sometimes cause even more damage.

But what if that immune response could be used to the patient’s advantage? “We’re trying to understand how we can harness the immune system’s knowledge about how to repair tissues after they’ve been injured,” says Lauren Sansing, MD, Academic Chief of the Division of Stroke and Vascular Neurology. Her team is working to understand the biological signals guiding the immune response to stroke.

That knowledge can then direct the development of targeted therapeutics for the treatment of stroke that minimize early injury and enhance recovery. “We want to be able to lead research efforts that change the lives of patients around the world,” says Dr. Sansing.

Study: “Anti-Inflamatory” Diet Of Vegetables, Fruits, Coffee & Tea Lowers Heart Disease And Stroke Risks

Dietary patterns with a higher proinflammatory potential were associated with higher CVD risk. Reducing the inflammatory potential of the diet may potentially provide an effective strategy for CVD prevention.

Background

Inflammation plays an important role in cardiovascular disease (CVD) development. Diet modulates inflammation; however, it remains unknown whether dietary patterns with higher inflammatory potential are associated with long-term CVD risk.
