Tech That Prevents Chemotherapy-Induced Nerve Harm

Peripheral neuropathy nerve injury—which can also stem from diabetes, vitamin deficiencies, and different causes—impacts principally the ideas of the affected person’s fingers and toes. Signs vary from persistent tingling to excruciating ache. At present there are not any permitted preventative measures for the situation; most cancers sufferers attempt to handle it with painkillers or, in extreme instances, decreasing or stopping their chemotherapy, Bandla says.

Bandla is the scientific innovation supervisor at Paxman Coolers, a medical gear producer headquartered in Huddersfield, England. She is creating a wearable machine that cools an individual’s limbs. Referred to as the Paxman limb cryocompression system (PLCS), it’s designed to assist forestall nerve injury from sure kinds of intravenous chemotherapy medicine. The chilly temperature slows blood circulation to the realm, permitting much less of the injected treatment to succeed in the nerves there.

Bandla, who relies in Singapore, can also be a principal investigator on the N.1 Institute for Well being, the Nationwide College of Singapore (NUS), and on the Nationwide College Most cancers Institute of Singapore.

An energetic IEEE volunteer, she follows ikigai in her work with the group, she says, and he or she encourages different younger professionals to do the identical. She has overseen the launch of a number of profession improvement and mentorship packages for IEEE Girls in Engineering Singapore, IEEE Area 10 Girls in Engineering, and IEEE Area 10 Younger Professionals.

“Being an IEEE member,” she says, “has helped me nurture my objective in rallying my efforts towards creating significant affect.”

For “her management in patient-centric well being expertise innovation and galvanizing IEEE Younger Professionals to drive significant change,” she is the recipient of this yr’s IEEE Theodore W. Hissey Excellent Younger Skilled Award. The award is sponsored by the IEEE Photonics and IEEE Energy & Vitality societies, in addition to IEEE Younger Professionals.

“This recognition fuels me to proceed the work IEEE is doing globally to make the world a greater place,” she says.

Engineering is a superpower

Bandla had a tough time deciding whether or not to pursue drugs or engineering as a profession, she says, however she selected the latter as a result of it’s “a superpower that may make it easier to create issues to make life higher.”

After incomes her bachelor’s diploma in electrical and electronics engineering in 2009 from Anna College, in Chennai, India, she joined software program engineering firm Infosys in Mysuru, India, as a technical marketing consultant. She left three years later after being accepted into the neurotechnology doctoral program at NUS in Queenstown. Neurotechnology encompasses methods of immediately participating with the human mind and nervous system, together with brain-computer interfaces, magnetic resonance imaging, and brain-wave screens.

Bandla performed her analysis beneath biomedical engineer Nitish V. Thakor, who makes a speciality of creating brain-monitoring applied sciences and neuroprostheses. The IEEE Life Fellow is a professor of biomedical engineering at Johns Hopkins College, in Baltimore. He is also director of the Singapore Institute for Neurotechnology, SINAPSE, a collaboration amongst six analysis universities together with Johns Hopkins, NUS, and the College of Patras, in Greece.

Underneath Thakor’s tutelage, Bandla started her work in creating the expertise she is concerned with right now.

Utilizing expertise to handle nerve injury

In 2012 Bandla and different researchers from Thakor’s lab met with neurologist Einar Wilder Smith and oncologist Raghav Sundar from Nationwide College Hospital in Kent Ridge, Singapore, to discover how the expertise might assist most cancers sufferers with peripheral neuropathy.

Throughout chemotherapy, sufferers are injected with an individualized drug combination that kills fast-dividing cells or prevents them from multiplying by damaging the cells’ DNA. However the combination can also assault wholesome cells and injury nervous-system buildings, inflicting ache and sensitivity within the affected person’s fingers and toes, as defined in an article printed within the Worldwide Journal of Molecular Sciences.

Within the assembly, the group discovered a couple of scalp-cooling expertise that helps forestall a distinct aspect impact: hair loss. A particular cap is positioned on the affected person’s head to chill the scalp.

Impressed by that chilly cap, the group got down to develop comparable expertise for the fingers and toes. However first, in 2014, the SINAPSE lab performed a scientific trial with Nationwide College Hospital to see if cooling the limbs would assist sufferers with peripheral neuropathy. Present localized cryotherapy machines used for sports activities remedy—which flow into ice-cooled liquid to chill an space on the physique, have been examined on 15 chemotherapy sufferers on the hospital. The group discovered that sufferers couldn’t comfortably tolerate temperatures beneath 22 °C throughout the three-hour therapy, Bandla says.

“Being an IEEE member has helped me nurture my objective in rallying my efforts towards creating significant affect.”

She advised conducting one other scientific trial, this time testing cryocompression instruments moderately than cryotherapy ones. Cryocompression is used for sports activities remedy and rehab. It combines cooling and compression—which helps scale back swelling. Within the second trial, the group discovered that sufferers might tolerate temperatures as little as 11 °C for 3 hours, Bandla says.

The second trial resulted in 2017. Bandla earned her Ph.D. that yr however continued to work on the undertaking as a SINAPSE analysis fellow.

In 2018 the group members started one other scientific examine, testing if they may safely cool a affected person’s scalp and limbs concurrently to forestall a number of uncomfortable side effects without delay.

All through the five-year trial interval, Bandla collected information to grasp the easiest way to ship cooling remedy that was protected, comfy, and efficient. The suggestions she acquired from sufferers, caregivers, and the medical workers demonstrated a transparent want for a tool to make use of within the chemotherapy suite.

After the pilot trials resulted in 2019, the group started designing a tool alongside Richard Paxman and his group at Paxman Coolers, who leveraged their experience in cryotherapy for side-effect administration.

The moveable PLCS connects to 4 insulated wraps, every containing a bladder full of coolant. The wraps cowl a affected person’s forearms, fingers, shins, and toes and embrace velcro flaps that may be adjusted for a greater match. The PLCS circulates the coolant by way of the wraps and powers the compression. It additionally retains the coolant temperature at 11 °C.

Throughout each chemotherapy cycle, half-hour earlier than the treatment is run, the wraps are positioned on the affected person’s forearms and shins to start the cooling course of. After the session ends, the machine is used on the affected person for 30 extra minutes, Bandla says.

The group was granted two U.S. patents for the PLCS.

In 2022 Bandla joined Paxman as a analysis and improvement supervisor, and he or she was promoted to scientific innovation supervisor two years later.

The affect her work has had retains her motivated to proceed, she says.

The PLCS is being examined in a large-scale scientific trial in 25 U.S. hospitals in collaboration with the Nationwide Most cancers Institute.

Beginning her IEEE volunteer journey

Thakor launched Bandla to IEEE. An energetic member of the IEEE Engineering in Medication and Biology Society, he encourages his college students to take part in its conferences and to publish papers in its journals.

Bandla says volunteering with IEEE was a no brainer for her. Her volunteerism started in 2012 with IEEE Girls in Engineering Singapore. In 2019 she grew to become its chair and launched the WIE Singapore Networking Night time to assist construct camaraderie between the IEEE Singapore Part and technologists in business, academia, and authorities. The annual occasion contains panel discussions.

In 2021 Bandla joined the IEEE Area 10 Girls in Engineering committee because the technical and Younger Professionals lead. There she helped launch MentorHer, an eight-week program by which consultants assist their mentees design and implement a skilled improvement plan. Bandla created this system’s framework.

“After the pilot program was accomplished in 2021, we acquired good suggestions from members,” she says. “Many individuals stated they interacted with individuals they wouldn’t usually work with and loved the expertise.”

In 2020 Bandla started collaborating in digital occasions and conferences held by Area 10’s Younger Professionals group as a speaker and panel moderator. Final yr she grew to become the chair.

Guiding younger professionals

Volunteering for the YP group is particular to her, she says, as a result of she has been capable of “construct a group and assist different younger professionals turn out to be well-rounded leaders and decision-makers.”

She helped develop the Profession and Management Assist Program (CLAP) on the Area 10 College students, Younger Professionals,Girls in Engineering,Life Members Congress held in August in Tokyo.

She launched the idea of ikigai to younger professionals by centering the occasion round it. The congress included what she calls a “human library” session. Ten IEEE members from totally different engineering fields have been positioned across the assembly room, and attendees had an hour to find out about every of the “human books.”

The group acquired optimistic suggestions, with members saying they loved the concentrate on skilled and management improvement. They stated they favored how extraordinary the occasion was, particularly the “human library” session.

Based mostly on the success of the CLAP occasion, the group is constructing an IEEE Hive. The immersive skilled improvement program is accessible for college students and early profession professionals at technical conferences and congresses all over the world.

The flexibility to make an affect, construct a group, and join with individuals resonates together with her, Bandla says.

“Volunteering with IEEE provides me a lot vitality!” she says.
