Diagram comparing normal eye and myopia (nearsightedness). The image shows light rays properly focusing on the retina in a normal eye, while in a myopic eye, light rays focus before the retina, causing distant objects to appear blurry.

Myopia Epidemic

Myopia, or near-sightedness, has been steadily on the rise over the last half-century. A recent systematic review updates the literature on the extent and nature of this epidemic. Let’s get straight to the findings and then discuss what this means. The reviews includes: “276 studies, involving a total of 5,410,945 participants from 50 countries across all six continents.” The researchers find a...

Line graph titled "Age at Initial ADHD Diagnosis Over Time" showing trends from 2010 to 2022. Lines represent different age groups with 6 to 11 years showing the highest increase post-2013. Other groups: 12-17, 18-22, 23-29, 30-49, 50+, and 1-5 years.

Why Is ADHD On The Rise

Attention-deficit/hyperactivity disorder (ADHD) is one of the most commonly diagnosed neurodevelopment disorders and seems to be on the rise, in both children and adults. The diagnosis in children requires having various symptoms of attention deficit or hyperactivity which is functionally impairing with onset by age 12. Recognition of the disorder actually goes back farther than you might think – the observation that...

Update on AI in the Clinic

It seems there is an endless stream of artificial intelligence (AI) news coming out, and this includes the field of medicine. There also continues to be a debate about the true impact of AI – how much is hype, and how much is a genuine advance that can transform our technology? As with many technological advances, it’s both. New tech, perhaps especially...

A silhouette of a man in a suit holds a smartphone, standing in front of a background with Wi-Fi signal icons and concentric circles emanating from the phone. The imagery suggests a connection between technology, communication, and connectivity.

WHO Systematic Review of RF and Cancer

In our increasingly technological world, we are constantly exposed to radio frequency electromagnetic waves (RF-EMF). It would certainly be inconvenient, to say the least, if this ubiquitous and essential technology had negative health effects. But of course we would need to know if this were the case so that steps could be taken to fix it. Fortunately, a recent systematic review conducted...

Are We Ready for Mpox

Are we ready for the next potential pandemic? It seems like we are just get over COVID and already we have to worry about the next one. We first covered the monkey pox (now mpox) in 2022. Since then it has continued to be a concern. Where do our efforts to contain this infection stand? To recap, the disease mpox is the...

An illustrated human body diagram showing the effects of COVID-19 on various organs. Key areas labeled include the brain (cognitive impairment, stroke), lungs (cough, shortness of breath), skin (bruising, rashes), nose (loss of taste or smell), heart (pounding heart, heart failure), and kidney (increased risk of acute injury and failure).

More on Long COVID

It’s interesting to follow the scientific exploration of a new clinical entity in real time. It reveals a lot about how medical science works, and how scientists nibble away at complex problems. This is partly why I have been closely following the story of long COVID as it has unfolded over the last few years. I also see patients with long COVID...

Vaccines for Children Program Works

We have often stated here on SBM that vaccine programs are the most effective, and most cost-effective, public health measures in human history. They save lives, prevent disease, and save money. These benefits are all well researched and copiously documented. A recent CDC study adds to the literature on the benefits of vaccines and vaccine programs, focusing on the effects of the...

Acupuncture and Evidence Based Medicine

Over the last few decades there has been a steady infiltration of acupuncture into Western mainstream medicine. It is not unreasonable to conclude that acupuncture’s journey from an exotic Eastern practice to a fringe treatment to mainstream acceptance has been complete. Knowledgeable proponents of science based medicine (SBM) who remain skeptical of acupuncture now find themselves on the fringe. How did this...

The Evidence for Rehabilitation Robots

Rehabilitation robots, first introduced in the 1990s, are just what they sound like – robotics used to aid in regaining function through rehabilitation following an injury. The idea sounds compelling, and the technology has been advancing steadily. But still we have to ask ourselves the question – do they actually help, and what is the evidence? A recent comprehensive meta-analysis and systematic...

Conspiracy Medicine

Was COVID cooked up in a lab? Do “they” have a cure for cancer and are hiding it from the public? Do pharmaceutical companies make up diseases to market otherwise failed drugs? Did insurance companies scheme with infectious disease professional organizations to suppress treatments for chronic Lyme disease? Did the supplement industry lobby congress to weaken regulations of their own products? OK,...
