Retina Scan for Diabetes Could Also Reduce Deaths During Pregnancy in Developing Countries (gatesnotes.com) 18

This week Bill Gates wrote a blog post about a special camera from medtech startup Remidio, which delivers high-resolution images of a patient's retina in seconds. The camera plugs into a phone running an AI system that watches for early signs of diabetes — all without needing a blood draw, eye dilation, or a dibetes specialist. It's already been used in 40 countries for more than 15 million patients. But that same hardware, with different software, can also flag the conditions that drive so many dangerous pregnancies. Gestational diabetes sharply increases the risk of pre-eclampsia [a spike in blood pressure during pregnancy responsible for half a million fetal deaths every year and 70,000 maternal deaths]... In most of rural sub-Saharan Africa or South Asia, it usually isn't screened for at all, because the standard test requires a lab. A retinal scan offers a different way in.

Remidio's device is currently being used in India to screen pregnant women for conditions that drive stillbirth. And researchers are now adapting the same hardware to screen for anemia and hypertension, too... [S]mall, portable, affordable diagnostics in the hands of community health workers are exactly the kind of lever that can start to move a number that hasn't moved in a long time.

    Apparently your blue sensing photoreceptors in your eye are super sensitive to blood sugar, and you could do a blood sugar test with a color calibrated phone app having people compare two shades of blue side by side. If you can't tell them apart, your blood sugar meets/exceeds/is below a certain threshold. It's not hyper accurate but useful for diabetics.

  • We have been doing a great job reducing prenatal deaths as well as all other forms in these countries, but there is a problem that is a bit sensitive. This will result in a lot of population growth, and the need for a lot more food.

    It does sound a little harsh, but both should occur in tandem. Less children born, but more survive.

      They do.

      Also, by "these countries" I hope you include the United States, Europe, wherever you happen to be from. You could also just leave out the phrase entirely and it would be more accurate.

        If. you are trying to contradict me, as if we need to reduce the fertility rate in teh USA - You chart shows something different entirely, that the countries that are to be helped have the highest fertility rates.

        Simply reducing Child mortality as a mono variant intervention, in countries that have the highest birth rates does not stop people lowering that fertility rate to US levels. My point is, and I take it I have offended you with my bluntness - is that if you are going to allow more people to grow

          I'm not sure how to be clearer. I quoted what you said:

          Less children born, but more survive.

          This is what the graph shows. When more children survive, fewer are born. There's no need to make a comment about "these countries" or the sinister "both should occur in tandem." It's how all countries have developed. Roll time back to 1950 on the graph and the US is where Kenya is today. Spain was where Nigeria and South Soudan are.

          The only difference is the developing countries today are developing, and moving to l

  • High-res retinal scans can show Alzheimer's disease before symptoms start. I hope they add that to the software for this device too.

    • And, we hope they permanently attach this to your ID card and SSN, and use that scan as our new ID card and bank card! .. that, or a chip under your skin.

      And, it's not some religious thing (Mark Of The Beast)... who, 50 years ago, would've thought that we'd all have a computer in our wristwatch or in our pocket that could do all the things (and more) that UNIVAC did.

      It's been long talked about... either 'eye scan as a total ID; combining bank, SSN, ID into one, with links to all your social media accounts a

  • The cheap diagnostic is great. But what does the treatment cost? Perhaps that's one reason screening has been skipped to date.

  • Nice try, Dr. Notman!
