Sun exposure makes people both more and less likely to die of melanoma. How can that be?
Quick quiz question: two people are diagnosed with melanoma— Sarah Sunburn, an adamant sun-worshipper, and Paula Pale-All-The-Time, a fanatical sun-avoider. Who is more likely to die of the disease? The answer is pale-faced Paula. Surprised? Let me unpack this mystery and explain why sun exposure simultaneously kills people, while making the cancers they are […]Find jobs at Careers by KevinMD.com.

Meet Susan Potter: Immortal Corpse
At the age of 72, German immigrant Susan Potter was adamant about donating her body to science. Her body would be turned inside out and created into a 3D digital landscape of 6,900 photos for medical students to learn from. In 2015, her wish finally came true. In a storyforNational Geographic, journalist Cathy Newman details Potter ’s journey from living human to “immortal corpse.”Potter ’s body was donated to the National Library of Medicine’s Visible Human Project, a program started by Vic Spitzer and David Whitlock at the University of Colorado in 1991. At the time, they received a government contract grant ...

Contrast Agent for Optical Coherence Tomography Improves Imaging of Tissues, Vessels
Optical coherence tomography (OCT) is an imaging technique that allows ophthalmologists to view the eye’s blood vessels, to study the structure of tissues in various clinical and scientific applications. Though this technology is already widely used, there’s been a constant demand to improve its imaging resolution.
Researchers at Stanford have just added an interesting ingredient, namely nano-scale gold prisms, which can be injected into the bloodstream to significantly boost the quality of optical coherence tomography. The effect is so substantial that molecular-level details are able to be distinguished, pot...

Spray Gel Helps Prevent Cancer Spread Following Surgery
All too often after tumor resections cancers end up spreading to other parts of the body. Metastasis is not well understood, but researchers at University of California, Los Angeles, University of North Carolina, Chapel Hill, South China University of Technology, Guangzhou and Fudan University in China, have developed and tested a remarkable new gel that seems to prevent it from occurring.
The spray gel is designed to be used following a removal of tumors, applying it to the area following treatment. The gel is infused with calcium carbonate nanoparticles that hold onto an antibody that blocks the activity of the CD47 p...

Top Digital Health Stories of 2018: From Amazon And Google To Gene-Edited Babies
Instead of mind-boggling inventions, 2018 was the year when national governments, as well as healthcare regulators, started to embrace digital health technologies at scale. The year when Google, Amazon, Apple or Microsoft competed head-to-head for the biggest chunks on the healthcare market, and when the buzzword of the year award went to the blockchain. Here’s our guide to the top digital health stories from last year.

Tiny Wearable UV Sensor Can Help to Optimize Phototherapy
Researchers at Northwestern University have developed a “virtually indestructible” solar-powered UV sensor. Described as the world’s smallest wearable, the battery-free device is thinner than a credit card and smaller than an M&M candy, but can warn people about UV over-exposure and help clinicians to optimize dosing during light therapy.
Not knowing of Northwestern’s role in this technology, we recently covered the now available sensor when it was released as a L’Oreal product through Apple stores.
Light therapy has numerous applications, including blue light therapy for jaundiced newborns and UV therapy...

Artificial Intelligence Automatically Spots Polyps During Colonoscopies (Interview)
Artificial intelligence is making big strides in a variety of medical fields, including radiology, oncology, and even ophthalmology. Now a company called Wision AI, based in Shanghai, Cina, is adapting artificial intelligence vision software to help doctors spot polyps during a colonoscopy. The technology is meant for real-time use and the procedure itself doesn’t change much from existing colonoscopies.
We spoke with JingJia Liu, Cofounder and CEO of Wision AI about the company technology, how it works, and what it is capable of already.
Medgadget: Can you briefly describe your company’s technology and ...

Immunohistochemistry in the Differential Diagnosis of Cutaneous Basal Cell Carcinoma
Basal cell carcinoma and squamous cell carcinoma are two of the most common cutaneous tumors seen by pathologists. In the large majority of cases, the distinction between these two tumors is readily made on the basis of standard H&E morphology. However, many of us see cases from time to time that for one reason or another (minuscule biopsy, mishandled specimen, crushed beyond recognition, dryed out, poorly fixed, etc., etc.), it is difficult to know for certain whether one is dealing with a squamous carcinoma or a basal cell carcinoma. This month, we discuss several immunostains that can be of utility in approaching th...

I Got My Whole Genome Sequenced. Here ’s What I Learned.
Dante Labs sent me their Full DNA whole genome sequencing package, and I went through a roller-coaster of feelings: I was excited to know every secret of my cells, but I was afraid to get to know my hereditary cancer risks and worried what I might find. As in my case, (scientific) curiosity usually overrides fear, I jumped into the unknown and I’m eager to share my results here.
Whole genome sequencing is available to anyone. So what?
The human genome is the blueprint for building a person. When the Human Genome Project was completed in 2006, and the DNA double spiral uncovered its secrets for the very first time, scient...
