Survival Chances For Cardiac Arrest During CPR

Posted by in categories: biotech/medical, health, neuroscience

According to a study published in the BMJ, a person’s chance of surviving cardiac arrest while receiving cardiopulmonary resuscitation (CPR) in a hospital is 22%, but that declines rapidly after only one minute to less than 1% after 39 minutes. The likelihood of leaving with no major brain damage is similar, declining from 15% after one minute of CPR to less than 1% after 32 minutes without a heartbeat.

Only around 25% of patients survive to hospital discharge after being admitted to the emergency department for cardiac arrest. This common catastrophic medical emergency with a high mortality rate is an important public health issue, affecting around 300,000 adults every year in America alone. Unfortunately, studies have shown that long resuscitation times are linked to lower odds of survival, but there are no specific recommendations on when to stop resuscitation.

A light touch: Changing the way we treat traumatic brain injury

Posted by in categories: biotech/medical, health, neuroscience

Contrary to popular perception, traumatic brain injury (TBI) is not the reserve of car accidents and punishing contact sports; it’s surprisingly common. Up to 50 million new cases of traumatic brain injury are registered each year worldwide. Notably, 80% of TBI occurs in low-to middle-income countries, and it is also the leading cause of death and disability in young adults. Overall, the global economic burden of TBI is estimated at 400 billion USD.

Minimising the devastating effects of TBI doesn’t rely solely on reducing the risk of an injury; it’s also essential to improve treatment after one has happened. For that, physiological real-time monitoring of vital signals is critical. One inventor has made it his mission to create devices that can do this accurately, easily, anywhere, and what’s more, they are also non-invasive.

Professor Arminas Ragauskas is a founder and director of the Health Telematics Science Institute at Kaunas University of Technology in Lithuania, which develops innovative industrial and physiological measurement and process monitoring technologies. He is particularly known for his work on non-invasive intracranial pressure and cerebral blood flow autoregulation measurement devices. He was also the national coordinator of the CENTER-TBI project, funded by the European Commission and the EU industry, with a budget of 40 million EUR, and focused European efforts to advance the care of patients with traumatic brain injury.

Let’s build the GPT Tokenizer

Posted by in categories: health, information science, robotics/AI

W/ Andrej Karpathy


The Tokenizer is a necessary and pervasive component of Large Language Models (LLMs), where it translates between strings and tokens (text chunks). Tokenizers are a completely separate stage of the LLM pipeline: they have their own training sets, training algorithms (Byte Pair Encoding), and after training implement two fundamental functions: encode() from strings to tokens, and decode() back from tokens to strings. In this lecture we build from scratch the Tokenizer used in the GPT series from OpenAI. In the process, we will see that a lot of weird behaviors and problems of LLMs actually trace back to tokenization. We’ll go through a number of these issues, discuss why tokenization is at fault, and why someone out there ideally finds a way to delete this stage entirely.

TB vaccine shrinks liver cancer tumors in mice

Posted by in categories: biotech/medical, health

A UC Davis Health study found that a single dose of Bacillus Calmette-Guérin (BCG), the vaccine for tuberculosis (TB), reduced liver tumor burden and extended the survival of mice with liver cancer. The study, published in Advanced Science, is the first to show the promising effects of the vaccine in treating liver cancer.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer. It is also the third leading cause of cancer-related deaths worldwide. Current therapies include surgery, radiotherapy, chemotherapy, immunotherapy and liver transplant. Yet, the therapy outcomes for liver cancer remain bleak.

BCG, the century-old TB vaccine, is derived from the live bacteria Mycobacterium bovis. It is considered safe and widely used around the world.

US-Mexico border: 100 billion gallons of toxic sewage creating a ‘public health crisis’

Posted by in category: health

“South San Diego County is in a total state of emergency related to transboundary pollution, and this is a public health ticking time bomb,” Imperial Beach Mayor Paloma Aguirre told ABC News. “We are living in conditions that nobody in this great nation should be living in.”

The Tijuana River – which has been classified as an impaired water body, according to the U.S. Clean Water Act — flows north for 120 miles from Mexico to California before reaching the Pacific Ocean on the U.S. side of the border in the Imperial Beach, San Ysidro and Coronado coastal areas.

Over the last five years, 100 billion gallons of untreated sewage, industrial waste and urban runoff have been dumped into the Tijuana River, according to the International Boundary and Water Commission.

‘All of Us’ reports half of the genomes it has sequenced are from non-Europeans

Posted by in categories: biotech/medical, genetics, health

Although people of European descent account for less than one-quarter of the world’s population, their DNA disproportionately drives genetics research. Between 2005 and 2018, the majority of genome-wide association studies were conducted with data from people living in just three countries — the United Kingdom, the United States, and Iceland.

“The paradox of precision medicine is that you have to have a ton of different kinds of people to figure out one person really well,” said Josh Denny, CEO of the All of Us research program. “There’s still so much we don’t understand about the human genome, especially about rare variation. Huge projects like ours are really helping to accelerate that understanding.”

All of Us has recruited more than 750,000 volunteers to provide survey responses about their health, medical records, and if they’re willing, biological samples for molecular and genetic testing. Genetic data from some participants have been available for researchers since 2020, but the new release this week includes the whole genome sequences of nearly 250,000 participants — half of whom are of non-European ancestry.

NASA looking for 4 volunteers to spend a year living and working inside a Mars simulator

Posted by in categories: biotech/medical, health, space travel

Ever wonder what it’s like to live on Mars? Now, you could try out life on the Red Planet – in a simulation run by NASA. The space agency is looking for participants to live on a fake Mars for a full year to help them prepare for human exploration of the planet.

This is the second of three missions, which will have four volunteers living in a 1,700-square-foot Mars simulation, NASA has announced. The missions, called CHAPEA, for Crew Health and Performance Exploration Analog, take place in a 3D-printed Mars habitat at NASA’s Johnson Space Center in Houston, Texas.

The simulation, called the Mars Dune Alpha, simulates a future Mars habitat with separate areas for living and working. It includes four living quarters for each volunteer, a workspace, a medical station, lounge areas and a galley and food growing stations.
