Practice makes perfect

Houston company is using 3D printing to enhance surgeon training and prevent avoidable patient deaths

It is no surprise that, when a company offered life-like bladders for medical training, Houston urologists jumped at the opportunity — many had to learn the surgery by operating on bell peppers.

This sort of produce practice is the traditional method for teaching surgeons. Before a doctor ever makes an incision on a living person, they'll practice surgery on food — slicing bananas open and sewing grapes back together.

But for a pair of Baylor College of Medicine-educated doctors, that didn't seem like sufficient prep for working with living bodies; fruit surgery was not fruitful enough. In 2014, Drs. Jacques Zaneveld and Smriti Agrawal Zaneveld founded Lazarus3D to build a better training model — and layer by layer, they created models of abs and ribs and even hearts with a 3D printer.

"We adapted pre-existing 3D printing technology in a novel proprietary way that allows us to, overnight, build soft, silicone or hydrogel models of human anatomy," says Jacques, who serves as CEO. "They can be treated just like real tissue."

This isn't 3D printing's foray in medicine. In 1999, doctors in North Carolina implanted the first 3D-printed bladder in human bodies — they covered the synthetic organs in the patients' cells so that their bodies accepted them. Since, researchers have continued to find uses for the technology in the field, printing other organs and making prosthetic limbs.

But the Lazarus3D founders felt like medical training was lagging behind. Even cadavers, which medical schools also use to prepare doctors for surgery, don't represent a healthy human body or the diseased state of a hospital patient, said Smriti, who works as the research director.

The pair turned their kitchen into a printing lab and set to work, creating life-like models of human organs. They didn't have to go far after their first successes to find potential buyers — they just went to Starbucks. In a coffeeshop in the heart of the Medical Center, they talked loudly about their product until the neighborhood doctors and researchers took interest and gathered around.

Over the next few years, the Lazarus3D team pooled resources and contacts and, a summer after opening, they moved out of their kitchen and into an office. They now are a Capital Factory portfolio company and have partnerships with Texas Children's, Baylor College of Medicine, MD Anderson Cancer Center, and others, providing organs for specialized training — and the more they expand, the more they're able to prepare doctors for invasive, sometimes dangerous procedures.

"There are over 400,000 deaths annually in the U.S. due to medical error," Smriti says. "Not all of them are due to surgical mistakes, but all of these, nonetheless, were preventable."

The models can also be used for explaining to patients in a visual way what surgeries they're about to receive — the black and grey smears on an MRI scan might not actually help a patient understand much about what a surgeon is going to do to their body. In 2018, Lazarus3D won a contest with NASA on the potential for 3D printing organs in space, so that major surgeries might be performed there. And the printed organs can also be used by researchers to safely develop new surgery methods.

This year, the company grew to seven people and aims to expand even more to add to its sales and manufacturing teams. Having been funded mostly by friends and family investors, Lazarus3D plans enter its first equity round this year. They're raising $6 million.

"Every generation in medicine, people look back at what was done before and think 'Man, that was barbaric,'" Jacques said. "Fifty years from now, we're going to look back and think, 'Man, back then we used to just give someone a patient to learn how to do physical skills on? That seems crazy.'"

It’s a grinch's cyber-playground, and this holiday season, you’re at risk — even if you think it won’t happen to you.

The good news is you can protect yourself from scams and fraud. Just remember that cybercriminals don’t discriminate, they can prey on anyone.

These statistics may surprise you:

  • Anxiety about having a mobile device hacked differs by demographic; low-income Black women rank mobile security as their number one concern, while the general population ranks mobile security as their third largest concern, according to a recent Recon Analytics survey of more than 3,297 U.S. consumers.
  • 44 percent of millennials have been victims of online crime in the last year and 31 percent admit they share their passwords with others.
  • Romance scams resulted in the most financial losses for adults aged 60 and over
  • Younger consumers took fewest actions after being notified of a data breach affecting their identity/online accounts in Q1 2022
  • Nearly 50 percent of American gamers have experienced a cyberattack on their gaming account or device
  • 47 percent of women who live in cities say their identities and/or data has been compromised in the past 6 months due to lack of home internet protections, compared with 53 percent of city men who say the same thing, according to a recent Recon Analytics survey.

People everywhere, regardless of gender, race, income level, education, or age, deserve to feel safe online. And yet, many aren’t aware how to protect themselves, don’t make it a priority, or wait to act until they are alerted to suspicious activity.

With words like malware, phishing, spoofing, and encryption, learning to protect yourself can feel like a college-level course. But it doesn’t have to be that complicated.

Top 5 ways to guard against cyberthreats

By following five simple steps, you can start to protect your network, devices and data from many digital threats.

  1. Understand cyberattacks are real. One of the first hacks was documented in 1963 and today, nearly 60 years later, hackers are attacking phones and computers every 39 seconds. Cyberattacks continue to grow in number every year.
  2. Be proactive. Don’t wait for an attack to happen. Monitor your accounts daily so you are the first to know if suspicious activity is occurring. Check with your wireless carrier to see if they have tools to help. AT&T customers can download the free ActiveArmor mobile security app to help block spam calls and secure their personal data. And ask your internet provider about extra layers of security available to you at home. AT&T Fiber customers can access AT&T ActiveArmor internet security features at no additional cost to them.
  3. Step up your mobile security. Mobile devices now account for more than 60 percent of digital fraud. Mobile banking, online shopping, streaming videos and storing documents make our phones a central location for sensitive information. Your wireless carrier may be able to help. AT&T offers advanced security like Public Wi-Fi Protection, Identity Monitoring and Safe Browsing for no extra charge with some of our plans. Check with your carrier to make sure they’re doing what they can to keep you safe.
  4. Protect your passwords. We all know it’s necessary, but not all of us take steps to do it. 68 percent of people admit to using the same password across multiple logins. Using a strong password that differs from site-to-site will help decrease your chances of being hacked. If you struggle with passwords, consider getting a password manager.
  5. Report suspicious text messages. As mobile operators have more success blocking illegal robocalls, scammers have turned to text messages. But now it’s easier than ever to report spam texts to help block and control them. The latest iOS and Android operating systems have a simple reporting feature in their Apple and Google messaging apps.
