Emotional ‘Grit’ Related to Function After Rotator Cuff Surgery

Joan S. Reed

SAN DIEGO — A recent study suggests patients who have low “grit” may have worse functional outcome following rotator cuff surgery. Researchers from the University of North Carolina presented data on 126 patients undergoing rotator cuff repair (RCR) correlating a patient’s level of grit with functional outcomes following surgery.

The term “grit” recently was popularized with the 2016 publication of the book  Grit: The Power of Passion and Perseverance  by Angela Duckworth. Grit is defined as the ability to persevere and maintain a passion for long-term goals

Duckworth, a psychologist and and popular-science author, introduced readers to her work on the Grit Scale, a validated twelve-question measure that has been shown to correlate with achievement.

“There has been increasing evidence of the role psychosocial factors play in patient outcomes following orthopedic procedures,” Kurt Stoll, MD, lead author on the paper, told Medscape Medical News. “Given

Coffea Cruda Homeopathic Remedy Uses, Benefits, Side Effects

Joan S. Reed

Coffea cruda is a homeopathic remedy made from unroasted coffee beans. Homeopathy is a form of alternative medicine developed about 200 years ago by German doctor Samuel Hahnemann. It’s based on two principles not supported by science:

  • Principle of similarity. A disease can be cured with a remedy that produces similar symptoms as a condition in healthy people. For example, coffee is a stimulate so some proponents of homeopathy believe Coffea cruda can help treat people who are overstimulated.
  • Law of minimum dose. The lower the dose of a treatment, the greater its effectiveness.

Despite a lack of evidence, some people believe that Coffea cruda can treat a variety of conditions like:

There’s little evidence to no evidence to support homeopathy as an effective medical treatment. The few studies that have found potential benefits of Coffea cruda:

  • are animal studies
  • have limited sample sizes
  • have conflicts of interest
  • have a

Breakthrough achievement in quantum computing — ScienceDaily

Joan S. Reed

A University of Texas at San Antonio (UTSA) researcher is part of a collaboration that has set a world record for innovation in quantum computing. The accomplishment comes from R. Tyler Sutherland, an assistant professor in the College of Sciences Department of Physics and Astronomy and the College of Engineering and Integrated Design’s Department of Electrical Engineering, who developed the theory behind the record setting experiment.

Sutherland and his team set the world record for the most accurate entangling gate ever demonstrated without lasers.

According to Sutherland, an entangling gate takes two qubits (quantum bits) and creates an operation on the secondary qubit that is conditioned on the state of the first qubit.

“For example, if the state of qubit A is 0, an entangling gate doesn’t do anything to qubit B, but if the state of qubit A is 1, then the gate flips the state of

Is climate writing too obsessed with “the science”?

“We are a great nation. A nation of science, of the Enlightenment, of Louis Pasteur,” said Emmanuel Macron in an effort to persuade a recalcitrant French public to get vaccinated against Covid. Science was offering people a way to protect themselves and they should have confidence in its ability and in progress more generally, argued the president. In richer nations, like France, the majority of unvaccinated people are those who have chosen not to get jabbed, with many doubting science.

Covid and climate change are two areas where this tendency towards doubt seems particularly strong. I have no idea what the US scientist Steven Koonin’s views are on the pandemic, but his takedown of climate science in his new book, Unsettled, follows a similar logic to that posited by those sceptical of anti-Covid measures. “The Science” is being used to serve an end, “to
