They started with a question about what they can be done with light without exposing the patient to radiation.  The answer is, use infrared light. By taking advantage of in the visual spectrum of what humans can and cannot see, doctors at Washington University School of Medicine designed goggles that allow surgeons to see cancer cells not visible to the naked eye.

Samuel Achilefu, Ph.D., professor of Radiology, Biomedical Engineering and Biochemistry and Molecular Biophysics at WUSTL directs the Optical Radiology Lab, where the goggles were developed.

The entire body has billions of cells and if surgeons want to pick out just a few cells, they need them to stand out. The eyes cannot see infrared light and body does not absorb infrared light very well, Achilefu said.

“With that knowledge, we don’t want to obstruct what the surgeon is doing – you want them to see just what they are seeing with no obstruction at all and then we can make the cells just light in the region where they cannot see,” Achilefu explained. “And no part of the body gives off this light at all and the advance you have is this: even if it’s just a single cell, it’s like a light in the dark.”

They wanted the goggles to be lightweight, simple to use and provide powerful information to diagnose various diseases in the body.

“If we have glasses like this and we code signatures inside of it such that the cancers can pick up that light with eye sensitivity and ignoring every other thing around it, then we are in a very good position to find it,” Achilefu said.

For global applications goggles also need practical at the point of care, whether it is at home, in rural areas or advanced medical facilities.

“I wanted it to be something that has no footprint in the operating room so that people could move around easily,” he said. The results being no obstruction at all and they get all the cancer out.

The goggles took three years of work with students involving engineering, biochemistry, radiology-based imaging and wireless communication.

“I want to use this in rural Missouri, for example, or a remote area in Africa, and somebody here at Wash-U can guide surgery,” Achilefu said. “They can stay here and guide you with no limitation.”

With the goggles on, infrared dye placed on the cancerous tissue lights up blue if cancer cells remain, allowing surgeons to see and remove all traces of the disease.

“We’ve done about 11 breast cancer patients here at Wash-U,” Achilefu said. “What we want to solve here is recur rates. “Our goal here is to reduce that recur rate in breast cancer patients to near zero.”

Dr. Greg Fields has been using the goggles at Wash-U in melanoma surgeries.

“He can now use the goggles to see what he is looking at to make sure the cancer is not coming back,” Achilefu said. “So, we’ve done about 27 or 28 patients.”

The prototype from Wash-U is being used in China at the Fudan Liver Institute in Shanghai.

“We’ve done 11 patients in China with liver cancer,” Achilefu said. “Liver cancer is huge, a big problem in China.” Fudan is the largest liver institute in the world, he added.

The potential applications are vast.

“Anything that involves surgery should work,” he said.

A new, streamlined prototype goggle is currently under development. It will weigh less and have added features.

“So you will not be seeing a camera standing on the goggles anymore, instead … it will be within the arms,” Achilefu described.

The headband for the goggles will be flexible, to fit different head sizes.

Moreover, for surgeons who normally wear corrective eyewear, they may not be necessary because goggle 2.0 will take into account the wearer’s visual acuity.

“So you don’t have to worry if you wear glasses or you don’t wear glasses,” Achilefu said. “It knows blurriness, and it corrects for blurriness.”

One other important point about this invention to the greater St. Louis community is that patent-owner Achilefu wants to keep the work on this high-tech medical device here in St. Louis.

“I personally think we produce some of the best engineers here at Washington University and some of the best scientists you can imagine,” Achilefu said. “What if we had a high-tech company here, based in St. Louis as a footprint with which you can then [have a] platform to move to other parts of the world? There is something in me that says it should be here.”

Achilefu and his team are finalizing the prototypes and are seeking Food and Drug Administration approval so they can be widely disseminated.

“In fact, we have so many requests now from all over the world that we need to quickly move, get FDA approval for this so they can be used at clinical centers for brain surgery, for example.”

Oakland Conducts Its Biennial ‘Point in Time’ Homelessness Count

Oakland, along with other cities in Alameda County, conducted their biennial ‘Point In Time’ census count on Feb. 1 to gain a thorough understanding of the size and dispersion of the homeless population in the region. The Point In Time (PIT) count is federally required by the Housing and Urban Development Department as a requirement to receive funding and resources to tackle homelessness in the area.

Oakland, along with other cities in Alameda County, conducted their biennial ‘Point In Time’ census count on Feb. 1 to gain a thorough understanding of the size and dispersion of the homeless population in the region.

The Point In Time (PIT) count is federally required by the Housing and Urban Development Department as a requirement to receive funding and resources to tackle homelessness in the area.

David Modersbach, Grants Manager of Alameda County Health Care for the Homeless program, said that the methodology this time around was different, as this count had a much more personal “lived experience” aspect that previous counts did not have.

In 2022, the county relied more on statistical extrapolation and assumptions, but this year’s survey questionnaires allowed for details on substance abuse issues, how long someone has been living without proper housing, what resources people are in need of and much more.

“[The PIT count is] a critical opportunity for the county, Continuum of Care, and cities to understand the magnitude of homelessness in Alameda County. [The count] enables us to better allocate resources and implement effective programs to tackle this issue head-on in a compassionate and inclusive way,” Modersbach said.

St. Mary’s Center was one of the many meeting hubs across the county that hosted volunteers and community officials the morning of the count. The organization has been deeply involved in the effort to provide resources for unhoused people and others in need.

St. Mary’s is a nonprofit in West Oakland that helps seniors and preschool families with food and housing. Last year, the organization helped about 50 seniors find housing after they had fallen on hard times.

Sharon Cornu, executive director of St. Mary’s, said a lot of the older couples and individuals that come into the center have borne the brunt of the skyrocketing cost of living in the Bay Area. The most recent influx of seniors St. Mary’s has seen coming in for help has been made up of people who were evicted when the COVID-19-related moratorium on rent payment ended.

“Seniors are the fastest growing segment of the unhoused and the incredibly high cost of housing is driving them to the streets,” Cornu said.

Among the volunteers were workers with Operation Dignity, a nonprofit organization that helps veterans and those living on the street find shelter, transitional housing and supportive services.

“These are our stomping grounds,” Ivan Magana, program manager for Operation Dignity said.

Magana stated that his team was extremely familiar with the people residing in the encampments they were conducting the count in since Operation Dignity made many visits to these areas while doing community outreach. He said they had even informed some of the unhoused people they knew about the count a few days prior so they would not be alarmed when the enumerators showed up early in the morning to conduct the count.

Not everyone got the memo though, as the volunteers encountered an almost violent situation around the 6 a.m.  when a young woman living in a bus yelled at the Operation Dignity workers to leave her alone.

Luckily, the three-year experience Mangana has working with Operation Dignity and his knowledge of therapeutic health services, equipped him with the techniques needed to deescalate the tension. The woman soon realized who the volunteers were and apologized, he said.

Another volunteer and Operation Dignity worker, Yolanda Kirkpatrick, noted that she was initially hesitant because of the early schedule. She felt the time deterred others from participating, too.

Her prediction would come true as the hours went on and they continued to walk along 24th St in downtown Oakland and there was very little activity on the streets.

The volunteers shared similar sentiments. Although the community the people they were engaging for the count and surveys encounter tend to distrust outsiders, the PIT count was necessary for the city to receive the appropriate level of federal funds to address a crisis that is spiraling out of control in California.

A full analysis and report of the count will be made available in the summer.

For Cervical Cancer Month, Medical Community Focused on Education

January was Cervical Cancer Awareness Month. Physicians, advocates and others in the medical community commemorated the month by raising awareness about a form of cancer they say is highly preventable and treatable. Cervical cancer is caused by a virus called the human papillomavirus (HPV) and it develops slowly over time but can be prevented with proper care in girls as young as 13 years old.

January was Cervical Cancer Awareness Month.

Physicians, advocates and others in the medical community commemorated the month by raising awareness about a form of cancer they say is highly preventable and treatable.

Cervical cancer is caused by a virus called the human papillomavirus (HPV) and it develops slowly over time but can be prevented with proper care in girls as young as 13 years old.

Sonia Ordonez, an OBGYN and gynecology surgeon at Kaiser Permanente, stated that as soon as people with cervixes reach the maturity reproductive age, they should start taking preventative measures like getting the HPV vaccine. The vaccine involves a series of two-doses for people aged 9 through 14 or three-doses for people 15 through 45 years old.

“I see a lot of young women who can’t remember or may not have gotten [the vaccine] when they were younger, or maybe got one, but we can give them the series of vaccines and restart at any point in time,” Ordonez said.

She said that cervical cancer is not the only cancer caused by HPV. Strains of the virus can also lead to throat, anal and penile cancers.

Screening is also an effective way to check for cervical cancer and should be done every three years after someone turns 21, doctors recommend. It is best to start as early as possible to catch occurrences early.

Ordonez said that this cancer is also more likely found in people of color and has led to more deaths overall.

A Mayo Clinic article published last month stated that Black women are more likely to be diagnosed and die of cervical cancer, compared to White women in the U.S.

2,000 Black women are diagnosed every year with cervical cancer and 40% die as a result.

“This disparity is not due to genetic differences among White, Black or Hispanic women, but rather related to systemic racism, access to healthcare and socioeconomic factors,” Dr. Olivia Cardenas-Trowers, a Mayo Clinic urogynecologist, said in the article.

Ordonez stated that immigrant women are also highly susceptible to the cancer, as many Latin American countries may not have accessibility to screenings or lack of insurance makes it harder for them to get tested.

Hispanic women are 40% more likely to be diagnosed with cervical cancer, and 30% more likely to die from it, as compared to non-Hispanic White women, according to the Office of Minority Health.

Family medicine physician, Joy Anyanwu, stated that the pandemic contributed to hesitancy about getting cervical cancer screenings among some women. Other factors are people’s aversion to vaccines, parents not wanting to believe that their children are or will become sexually active, and doubt about the overall effectiveness of the vaccine.

“The vaccine is very safe — over 97% effective in preventing cervical cancer,” Anyanwu said. “Even if you aren’t having sex, the earlier you start would actually help.”

Anyanwu said she understands that parents might not want to ask questions about their children’s reproductive health, but it’s a mindset that can be a barrier to having important conversation about prevention or care.

To keep families their families and communties healthy, the doctor emphasized that people should prioritize keeping up with their vaccine series and going to screenings every year.
