The 48-year-old's diagnosis, which he revealed in 2024, is part of a concerning rise in colorectal cancer rates ― which groups together colon and rectal cancer because of their similarities ― in younger people throughout the world. A report by the American Cancer Society found that colorectal cancer diagnoses nearly doubled in people younger than 55 in recent years; it increased from 11% in 1995 to 20% in 2019.
The findings of a study conducted on a sample of 2.7 million people in Sweden over a 35 year period, and published this Thursday in the medical journal BMJ, suggest that the male to female ratio of Autism Spectrum Disorder (ASD) has decreased over time. In early childhood, before the age of 10, the male to female ratio is 3:1 (the most widely accepted ratio a few years ago was 4:1).
For decades, we've divided health into neat categories: mental health on one side, physical health on the other. The brain over here. The heart over there. Different specialists. Different appointments. Different silos. But biology doesn't respect those boundaries-and neither does depression. A growing body of research now makes something unmistakably clear: Depression is not only a disorder of mood and motivation; it is also a condition that affects the heart, blood vessels, and our long-term cardiovascular risk.
The genius of her approach is that she realised there was a goldmine of just such solid data waiting to be interrogated in the so-called cohort studies involving tens of thousands of people and extending over decades, which have been conducted in the UK as a function of epidemiological studies. They contain detailed medical information, including psychological data, as well as assessments of peoples' education, economic status, work and lifestyle.
Jonathan Caulkins reported that 2022 marked the year daily, or near-daily (i.e., at least 20 days each month), cannabis users outnumbered daily, or near-daily, alcohol users for the first time. While the total number of Americans consuming alcohol is still greater than those using cannabis, heavy users of each tells a different story. An estimated 17.7 million Americans use cannabis every day, or nearly every day,
Yeah, definitely. So in general lung cancer is the number-one cancer [killing]people in the U.S., both men and women. If you look at the American Cancer Society, around 226 new226,000 new cases of lung cancer are projected to be diagnosed in 2025. Of those about 50 percent are cancer-related deaths, meaning [roughly] 120,000 people die every year from lung cancer. Now, what'sthe good news is that the incidence has actually been decreasing in the last few years.
Contrary to overall cancer trends, there's been an increase in certain cancer diagnoses in people under 50. From 2010 through 2019, the incidence of 14 cancer types increased among people in this demographic. The big question is, why? Does it have to do with lifestyle choices? Are there environmental factors at play? What can be done to mitigate risk? Welcome to "Harvard Thinking," a podcast where the life of the mind meets everyday life.
The increase is real and global, rising from approximately 94,700 cases in 1990 to 225,736 in 2019. A study across Europe found that for those aged 20-29, incidence rose 7.9% per year between 2004 and 2016, with the rates increasing by 4.9% in those aged 3039, and 1.6% in the 40-49 group in roughly the same period. Not only is colon cancer increasing in every age cohort under 50, the growth rate is highest in the youngest group.
People with a psychiatric disorder are more likely to marry someone who has the same condition than to partner with someone who doesn't, according to a massive study suggesting that the pattern persists across cultures and generations. Researchers had previously noted this trend in Nordic countries, but the phenomenon has seldom been investigated outside Europe. The latest study, published in Nature Human Behaviour today, used data from more than 14.8 million people in Taiwan, Denmark and Sweden.
Pathogens have been a constant threat to human health throughout our evolutionary history. Infectious diseases are estimated to have been responsible for more than half of all children deaths before age 15.
A Devastating Error. In answer to that question, Zimmer reminds us of a now-infamous tweet the World Health Organization sent out on March 28, 2020... "FACT: #COVID19 is NOT airborne." This misinformation perpetuated misunderstanding about transmission.
When I was first starting out as a new research fellow in the field of mineral metabolism, I read many seminal papers that were published in the Journal of Clinical Investigation, which is the leading journal of the American Society of Investigation.
