What is AI?

AI is an entity that thinks / actshumanely / rationally

Mathematics

Linguistic

Psychology

Philosophy

According to Russel's, Norvig's

"Artificial intellegence: A modern approach"

To Build an Intelligent AI We Have to Be Good at:

Robotics

Machine Learning

Natural Language Processing

Automated Reasoning

Knowledge Representation

Computer Vision

Healthcare is not only about healing people but also about making the

healing process as stress-free, easy and cheap

as possible

Microbiome modification

Aging

Disease diagnosis /

cure

Novelty drug development

If it is a terrifying thought that life is at the mercy of the multiplication of these minute bodies [microbes], it is a consoling hope that Science will not always remain powerless before such enemies...

Diagnoses Conundrum

Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.

AI vs. Human Doctors

Physicians diagnostic accuracy is 85-90% From Semigran, H. L., et.al. Comparison of Physician and Computer Diagnostic Accuracy, JAMA Internal Medicine, (2016)

Physician and Symptom Chekers’ Diagnostic Accuracy, Stratified by the Acuity Level and Prevalence of the Conditions Described by the Clinical Vignettes

Let’s Make a Diagnosis

A 47-year-old woman was brought to the emergency department by her family because of 1 week of abdominal pain. The pain had begun in the epigastrium but had spread across the abdomen. She described it as constant and 10 of 10 in intensity but could not identify aggravating or alleviating factors. She also complained of nausea and vomiting, beginning 4 days prior to presentation, occurring two to five times per day. She noted poor oral intake and mild diarrhea. She denied melena or hematochezia. She reported no recent fever, dysuria, chills, or night sweats; however, she reported upper respiratory symptoms 2 weeks prior to presentation. On the day of presentation, her family felt she was becoming increasingly lethargic.

The patient had a history of nephrolithiasis and had undergone total abdomi- nal hysterectomy and bilateral salpingo-oopherectomy secondary to uterine fibroids. She took occasional acetaminophen, smoked two cigarettes per day, and rarely con- sumed alcohol. Temperature was 38.5◦C, heart rate was 160 beats per minute, respiratory rate was 28/minute, and blood pressure was 92/52 mm Hg; oxygen saturation was 100% breathing 2 L of oxygen by nasal cannula. She was a moder-ately obese African-American woman in moderate distress, lying in bed moaning. Mucous membranes were dry. There was no lymphadenopathy or thyromegaly.

This case nicely demonstrates a key teaching point: a fast regular heart rate of about 150, irrespective of the electrocardiogram, suggests atrial flutter. Who gets atrial flutter? Patients with chronic lung disease, myocardial ischemia (albeit rarely), alcohol-induced cardiomyopathy, and infiltrative cardiac disorders. Additionally, we also have to consider thyroid dysfunction.

Thyroid studies revealed thyroid stimulating hormone of less than 0.01 mU/L (normal range, 0.30–5.50)

She said, “Can you help me, Mr. Robot, sir?” The Talking Robot was designed to answer questions, and only such questions as it could answer had ever been put to it. It was quite confident of its ability, therefore, “I- can- help- you.”

Isaac Asimov,Robbie

"Nuttiest thing I ever heard of," said the President. "You have to punch out the questions on that thingamajig, and the answers come out on tape from the whatchamacallits. You can't just talk to it." A doubt crossed his fine face. "I mean, you can't, can you?” "No sir," said the chief engineer of the project. "As you say, not without the thingamajigs and whatchamacallits.”

Kurt Vonnegut, Player Piano

Physicians Spend 30% of their Time on Table Work

Just beneath the skin. Just above the heart. It records the heartbeat and sends out a signal and that signal is recorded on a monitor and when the signal stops a rescue squad is sent. ...and there it was, a little metallic thing, but it wasn't just a piece of metal; it was a man's life laying there.

“I will do cheese in batter.”

“How is that made?”

“Facilis. You take the cheese before it is too antiquum, without too much salis, and cut in cubes or sicut you like. And postea you put a bit of butierro or lardo to rechauffer over the embers. And in it you put two pieces of cheese, and when it becomes tenero, zucharum et cinnamon supra positurum du bis. And immediately take to table, because it must be ate caldo caldo.”

What hinders the adoption?

…political, fiscal or cultural nature rather than purely technical.

Visionaries, where are you?!

The technology exists today—including predictive analytics, robotic process automation, and AI-based tools, all digitally connected via the Internet of Things (IoT)—but no pharma company has fully leveraged it yet.

One needs visionaries - and not just pragmatists – to see the full potential of digitalization.

And, unfortunately, we are not very good at anticipating what the next emerging serious flaw will be.

Michael Jordan in "Artificial Intelligence — The

Revolution Hasn’t Happened Yet", 2018

AI and Automation

But this is something that we have seen over and over in the last so many centuries, where a breakthrough in technology, a significant innovation, creates fear and anxiety, does eliminate jobs. But by the same token, new jobs are created. And this is most likely what we are going to see.

Chrisitne Lagardein the interview to the Wall Street Journal

New technologies – such as digitalization, artificial intelligence, and automation – have the potential to change the nature of production processes, raise productivity, and reshape labor markets.

…requires first understanding the role of technology in shaping new production processes, with the concomitant changes in terms of productivity and labor market relationships.
