Permanently Boosting Levels of Natural Killer Cells in Mice to Increase Cancer Resistance
Researchers here demonstrate a very interesting approach to immunotherapy: they introduce engineered stem cells in mice that will give rise to additional natural killer T cells, boosting the capability of the immune system for the entire life span of the mouse. Even if this class of treatment is not actually permanent in the same way in humans, and merely long-lasting, it still seems a promising step towards enhancing the immune system at any age, not just trying to repair it when it fails in later life.
They've been called the "special forces" of the immune system: invariant natural killer T cells. Although there...

Keep using sunscreen while FDA updates recommendations on safety of sunscreen ingredients
This study is called an exploratory maximal usage trial (MUsT), because the sunscreen products were applied according to the maximum limit of the products’ directions for use, which likely far exceeds use by the average consumer.
Furthermore, while the FDA recommends that active ingredients in sunscreen that exceed 0.5 ng/ml should undergo toxicology testing to check for harmful health effects, this number is somewhat arbitrary, as it is not known what the significance of this blood level means. The FDA acknowledges that without further testing, we do not know what degree of absorption should be considered safe.
What is ...

Digital Skin Care: Top 8 Dermatology Apps
Each year 2-3 million non-melanoma and 132,000
melanoma skin cancers occur globally according to statistics from the
WHO. Thus, every tool has to be deployed for early detection and
intervention. As smartphone penetration already reached the quarter of the
Earth’s population, smartphone apps seem to be a viable way to go against skin
conditions. Here, we collected the top dermatology apps to aid your digital
skin care.
As smartphones take over the world, dermatology apps
multiply
As technology continues to advance, so too does its
accessibility to the general population. In 2013, only 56 percent of Americans
owned ...

Topical treatment helps prevent actinic keratosis from developing into skin cancer
In this study, 624 patients with multiple actinic keratoses were randomized to treatment with one of the four aforementioned field-directed treatments.
The primary endpoint of the study was the percentage of patients who had at least 75% reduction in their number of actinic keratoses after one year. The study found that the percentage of patients who achieved this goal was significantly higher in people treated with topical fluorouracil (75%), compared to those treated with topical imiquimod (54%), photodynamic therapy (38%), and topical ingenol mebutate (29%).
This seminal study highlights the important role of field-dire...

What Has A.I. In Medicine Ever Done For Us? At Least 45 Things!
Remember Monty Python’s
brilliant Life of Brian movie scene where the Palestinian insurgent commando,
planning the abduction of Pilate’s wife in return for all the horrors they had
to endure from the Roman Empire, asks the rhetorical question: what have the
Romans ever done for us? With the hype and overmarketing, not to speak about
the fears around A.I, we asked the same question. What has A.I. in medicine
ever done for us? Well, we found at least 45 things.
I have 45 responses to
the pressing question on everyone’s mind who is interested in healthcare but
tired of the hype or the doomsday
scenarios around A.I.: ...

Cancer treatment: Is a clinical trial right for you?
Clinical trials are research studies that test a new drug or therapy in patients who have a disease. These studies are classified as phase I, II, or III depending on their purpose.
Phase I: These initial, small studies test promising new drugs that effectively kill cancer cells in laboratory experiments. The goal is to understand the safe dose and capture early evidence of benefit. Phase I trials may be open to patients with any type of cancer, or only certain types of cancers more likely to respond to specific drugs. Generally, fewer than 50 patients are enrolled.
Phase II: Once a phase I trial identifies a safe dose, ...

Top Smart Algorithms In Healthcare
As artificial intelligence tools have been invading
more or less every area of healthcare, we made a list to keep track of the top smart algorithms aiming for better diagnostics,
more sophisticated patient care or further sighted predictions of diseases.
Does A.I. beat doctors?
Only if you lived under a rock for the last couple of
years, could you not have heard about artificial intelligence. Some might have even come
across the spread and potential of A.I. in healthcare. Not only
smart algorithms themselves but also the
hype around A.I. has grown immensely, thus every time a new study about deep
learning or machine...
