A team of South African doctors in the capital city Pretoria has been hailed as pioneers in the field of global medicine after performing the first-ever transplant of a patient’s middle ear.

The achievement–which used 3D-printed technology to reconstruct the broken bones of a middle ear–is being celebrated as a long-term solution to conductive hearing loss. What’s more, the surgery can be performed on people of any age, including newborn babies, curing patients of a form of deafness that is caused by physical damage or infection in the middle ear as well as congenital birth defects and metabolic diseases.

The first patient to undergo the procedure was a 35-year-old male who lost his hearing after a car accident devastated his middle ear. Due to the nature of his trauma, the operation lasted about an hour and a half, according to Legit.

The brains behind the medical team at the University of Pretoria’s Steve Biko Academic Hospital, Professor Mashudu Tshifularo, had been studying conductive hearing loss over the past decade, but in the past two years he began investigating the use of 3D printing technologies for the purpose of scanning and wholly recreating the smallest bones, or ossicles, of the middle ear–namely the hammer, anvil and stirrup.

In a celebratory press release issued by the South African Department of Health, Tshifularo is quoted as explaining:

“By replacing only the ossicles that aren’t functioning properly, the procedure carries significantly less risk than known prostheses and their associated surgical procedure.

We will use titanium for this procedure, which is biocompatible. We use an endoscope to do the replacement, so the transplant is expected to be quick, with minimal scarring.”

Tshifularo told local radio station Jacaranda FM:

“This was one of our patients we have been waiting for, for this reconstruction for almost three years now because they are not affordable … [but] we have done something new in the world and people will remember us for that.”

[WATCH] A pioneering surgical procedure using 3D-printed middle ear bones, developed by Professor Mashudu Tshifularo and his team at the University of Pretoria (UP) Faculty of Health, may be the answer to conductive hearing loss, a middle ear problem caused by congenital birth defects, infection, trauma or metabolic diseases.

While expressing pride that he was the first in the world to revolutionize the new approach to address hearing loss, Tshifulara remains steadfast that the treatment must eventually become accessible and affordable for poor and working-poor patients, such as those who use South Africa’s public hospitals.

Tshifularo continued:

“Because we are doing it in the country and we are going to manufacture here, it has to be affordable for our people in state hospitals.

It will be very accessible because as long as we can train the young doctors to be able to do this operation, then it will be accessible for them as well.”

For Tshifularo, “innovate or perish” sums up his approach to medical science–both in terms of education, research, invention and clinical procedures, and also in terms of devising new solutions to the array of problems faced by struggling communities.

He hopes that he and his team at the university’s Department of Otorhinolaryngology (Ear, Nose and Throat) will receive the necessary funding from the government and private sponsors to ensure that this innovative approach to hearing loss treatment can get off the ground.

South African Minister of Health Aaron Motsoaledi has already pledged that the Department of Health will “do everything in our power to assist and mobilize resources to make sure that Prof. Tshifularo gets all the help he needs for this far-reaching innovation.”

Biden to Ban Menthol Cigarettes, Citing Health Impact on Youth and Black People

The Biden administration is reportedly planning to propose an immediate ban on menthol cigarettes, a product that has long been targeted by anti-smoking advocates and critics who claim that the tobacco industry has aggressively marketed to Black people in the U.S.

On Wednesday, the Washington Post reported that the administration could announce a ban on menthol and other flavored cigarettes as soon as this week.

Roughly 85 percent of Black smokers use such menthol brands as Newport and Kool, according to the Food and Drug Administration. Research has also found that menthol cigarettes are easier to become addicted to and harder to quit than unflavored tobacco products, along with other small cigars popular with young people and African Americans.

Civil rights advocates claim that the decision should be greeted by Black communities and people of color who have been marketed to by what they describe as the predatory tobacco industry.

Black smokers generally smoke far less than white smokers, but suffer a disproportionate amount of deaths due to tobacco-linked diseases like heart attack, stroke, and other causes.

Anti-smoking advocates like Matthew L. Myers, president of Campaign for Tobacco-Free Kids, also greeted the move to cut out products that appeal to children and young adults.

“Menthol cigarettes are the No. 1 cause of youth smoking in the United States,” he said. “Eliminating menthol cigarettes and flavored cigars used by so many kids will do more in the long run to reduce tobacco-related disease than any action the federal government has ever taken.”

However, groups including the American Civil Liberties Group (ACLU) has opposed the move, citing the likelihood that such an action could lead to criminal penalties arising from the enforcement of a ban hitting communities of color hardest.

In a letter to administration officials, the ACLU and other groups including the Drug Policy Alliance said that while the ban is “no doubt well-intentioned” it would also have “serious racial justice implications.”

“Such a ban will trigger criminal penalties, which will disproportionately impact people of color, as well as prioritize criminalization over public health and harm reduction,” the letter explained. “A ban will also lead to unconstitutional policing and other negative interactions with local law enforcement.”

Pollution Is Making Human Penises Shrink and Causing a Collapse of Fertility, Scientists Say

With many still scoffing at the idea of rampant pollution posing a threat to humanity, a new study could drastically change the conversation: the chemicals across our environment could be the cause of shrinking human penises.

According to a new book by Dr. Shanna H. Swan, conditions in the modern world are quickly altering the reproductive development of humans and posing a threat to our future as a species.

The argument is laid out in her new book Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race.

The book discusses how pollution is not only leading to skyrocketing erectile dysfunction rates and fertility decline, but also an expansion in the number of babies born with small penises.

While it may seem like good fodder for jokes, the research could portend a grim future for humanity’s ability to survive.

Swan co-authored a study in 2017 that found sperm counts had precipitously fallen in Western countries by 59 percent between 1973 and 2011. In her latest book, Swan blames chemicals for this crisis in the making.

“Chemicals in our environment and unhealthy lifestyle practices in our modern world are disrupting our hormonal balance, causing various degrees of reproductive havoc,” she wrote in the new book.

“In some parts of the world, the average twentysomething woman today is less fertile than her grandmother was at 35,” she also wrote, noting that men could have only half the sperm count of their grandfathers.

Swan blames the disruption on phthalates, the chemicals used in plastic manufacturing that also have an impact on how the crucial hormone endocrine is produced

However, experts note that the proper implementation of pollution reduction measures could help humanity prevent the collapse of human fertility.

Visualizing The World’s Deadliest Pandemics By Population Impact

Humanity has been battling against disease for centuries.

And while most contagious outbreaks have never reached full-blown pandemic status, Visual Capitalist’s Carmen Ang notes that there have been several times throughout history when a disease has caused mass devastation.

Here’s a look at the world’s deadliest pandemics to date, viewed from the lens of the impact they had on the global population at the time.

Editor’s note: The above graphic was created in response to a popular request from users after viewing our popular history of pandemics infographic initially released a year ago.

Death Toll, by Percent of Population

In the mid-1300s, a plague known as the Black Death claimed the lives of roughly 200 million people – more than 50% of the global population at that time.

Here’s how the death toll by population stacks up for other significant pandemics, including COVID-19 so far.

The specific cause of the Black Death is still up for debate. Many experts claim the 14th-century pandemic was caused by a bubonic plague, meaning there was no human-to-human transmission, while others argue it was possibly pneumonic.

Interestingly, the plague still exists today – however, it’s significantly less deadly, thanks to modern antibiotics.

History Repeats, But at Least We Keep Learning

While we clearly haven’t eradicated infection diseases from our lives entirely, we’ve at least come a long way in our understanding of what causes illness in the first place.

In ancient times, people believed gods and spirits caused diseases and widespread destruction. But by the 19th century, a scientist named Louis Pasteur (based on findings by Robert Koch) discovered germ theory – the idea that small organisms caused disease.

What will we discover next, and how will it impact our response to disease in the future?
