New scan predicts heart disease risk within 5 years

  Cedars-Sinai Medical Center has developed a new AI tool that can accurately measure plaque deposits in coronary arteries and predict patients, according to a study recently published in The Lancet Digital Health. Likelihood of heart disease within 5 years.
  To create the tool, the researchers first trained an algorithm to identify plaque deposits using a dataset of images from 921 patients. The tool was then validated on a test set of images from hundreds of patients, and the results were nearly identical to the judgments made by human experts.
  The researchers further examined the tool’s ability to predict future heart attacks. The researchers found that it accurately divided patients into two groups, high-risk and low-risk patients for heart disease over a 5-year period.
  The technology is still in its infancy, and larger studies are needed to train the algorithm in different patient populations. Excitingly, in the future AI tools are expected to rapidly analyze diagnostic images to provide patients with immediate risk reports.

  Dogs are loyal companions of human beings. Because their lifespans are not very long, many people often regret that their dogs cannot accompany them all their lives. So how long do dogs of different breeds live? Why are some dog breeds more “short-lived”?
  A study published April 28 in Scientific Reports answers those questions.
  The life expectancy data of the 18 dog breeds involved in the study shows that the Jack Russell Terrier is the longest-lived dog in the UK and the French Bulldog is the shortest. The lifespan is generally shorter.
  Dan O’Neill of the Royal Veterinary College of England and colleagues analysed data from more than 30,000 dogs in the UK between 2016 and 2020. The team wanted to know the average life expectancy for each dog breed.
  ”Average lifespan doesn’t bring much detail,” says O’Neill. For example, if your dog has an average life expectancy of 10 years and he’s 9 years old, that doesn’t mean he’s going to die in the next year .
  ”It just shows that your dog might be healthier than a dog that died before reaching this average lifespan. So, it might actually live longer than average,” O’Neill said.
  By calculating the proportion of dogs that die each year after birth, the researchers created a lifespan table for each breed, which owners can use to estimate how long their dogs will live.
  O’Neill points out that this is an unprecedented study using a large sample size based on anonymised records of 30 per cent of veterinary surgeries in the UK. “It took 10 to 15 years to build this lifespan system.” The
  researchers found that Jack Russell Terriers had the longest life expectancy at 12.7 years, followed by Border Collies at 12.1 years. French bulldogs have the shortest life expectancy at 4.5 years, followed by English bulldogs at 7.4 years.
