Welcome Dr. David Lubarsky to UC Davis Health!

David A. LubarskyUC Davis Chancellor Gary May has appointed David A. Lubarsky to the position of vice chancellor of human health sciences and chief executive officer of UC Davis Health, which includes the School of Medicine, the Betty Irene Moore School of Nursing, the 1,000-member physician practice group, and UC Davis Medical Center, a 627-bed acute-care hospital. Lubarsky will join UC Davis on July 2, 2018.

Lubarsky most recently served as the chief medical and systems integration officer with the University of Miami Health System, a position he has held since 2012. As a leader within the system, he has overseen the system’s four hospital and practice chief medical officers as well as patient safety and quality. In addition, he led the university’s self-insured malpractice program, which focuses on prevention, and patient and visitor services, including patient experience. During his tenure at the University of Miami, Lubarsky integrated programs to create system-wide consistent approaches to care and quality improvement, including a new central safety and quality office, a system-wide safety and quality governing board, a system-wide chief medical officer council, a system-wide infection control and antibiotic stewardship program, and a central PI and project management office.

"David brings to UC Davis broad experience and proven results in a major healthcare market," May said. "He has an impressive record of sound financial management and innovative practices for a high functioning health care system that has gained national attention. His success in raising funds to meet pressing needs, including for enhanced access to Medicaid and indigent patients, aligns well with our values at UC Davis Health."

Lubarsky has been recognized for his success in helping establish a centralized scheduling system, improving infrastructure, and improving performance across many areas of the University of Miami health system. He raised more than $100 million annually for the University of Miami from state and federal funding sources to aid enhanced access for Medicaid and indigent patients. Previously, as CEO of the 1,100-physician practice, he turned a $100 million loss into a $32 million surplus in one year by growing patient volumes and optimizing the revenue cycle while making sure already high patient experience scores were maintained. Of note, every one of his major initiatives has explicitly prioritized quality and empathetic patient care.

In his efforts to meet community needs, Lubarsky has worked with the state of Florida and Centers for Medicare & Medicaid Services to expand access to Medicaid, forging a close partnership with the other major academic centers in Florida in pursuit of this goal. He has also been working with Florida’s state and congressional representatives to expand existing graduate medical education programs that would best meet the state’s needs and to secure the necessary federal funding which has been frozen for more than 20 years.

For the last 16 years, Lubarsky has been chief of service of anesthesia and pain management for the largest safety net hospital in the U.S., Jackson Memorial Hospital. He served on their board overseeing safety and quality, and throughout his tenure has been a forceful advocate for a uniform high quality of care.

"It is a privilege to join this highly regarded, progressive and nationally recognized health system," Lubarsky said. "I look forward to working closely with the accomplished faculty and staff, and routinely interacting with Davis’ talented students and trainees. I have already heard many great ideas about how to catapult Davis to greater heights, and I hope to harness those ideas to catalyze innovation so that we better serve our patients, our local community and our academic mission."

Neural stem cell discovery may aid in treatment research for deafness

(SACRAMENTO)

Researchers at UC Davis School of Medicine have for the first time shown that a polysialylated glycoprotein that regulates neurodevelopment exists on the surface of cells in the adult inner ear. This biomarker of early cells allows researchers to identify immature cells so that they can be used for further research and possible treatment. The discovery, published online in the journal Biochemical and Biophysical Research Communications, opens the door to developing stem cell replacement treatments in the inner ear to treat certain hearing disorders.

Frederic Troy Frederic Troy

“Hearing loss is a complex process and is usually regarded as irreversible,” said Frederic A. Troy II, principal investigator of the study and professor emeritus of biochemistry and molecular medicine, and a member of the UC Davis Comprehensive Cancer Center. “Finding this molecule in the inner ear that is known to be associated with early development may change that view.”

Having a biomarker for immature stem cells could make it possible to isolate neural stem cells from the adult inner ear in a person with hearing loss, induce their replication and maturation in the laboratory, and then re-introduce them back into the inner ear as functioning neurons. It is postulated that they may recolonize and establish themselves, thereby improving hearing.

During development, certain glycoproteins (carbohydrate-protein linked molecules) that are expressed on cell surfaces serve critical functions essential to the normal growth and organization of the brain. One member of the class of cell-surface glycoproteins is an unusual molecule called polysialic acid (polySia). Its large size fills up spaces between cells and its strong electric charge repels other molecules, qualities that help to prevent cells from adhering or attaching to one another and thereby promoting cell movement to other areas.

The predominant carriers of polySia in the brain are neural cell adhesion molecules (NCAMs), which are glycoproteins expressed on neuronal cell surfaces. As their name suggests, NCAMs by themselves are important in helping cells stick together and stay in one place. But when an NCAM becomes modified with polysialic acid (becomes “polysialylated”), the cells gain the ability to migrate to new areas. Re-expression of the “anti-adhesive” polySia glycan on the surface of many adult human cancer cells, for example, facilitates their detachment, thus enhancing their metastatic spread. PolySia found on human leukocytes also modulates immune function.

Neural stem cells with these polySia-NCAMs on their surfaces are important in embryonic development because they are able to travel throughout the body where they can differentiate into specialized cells. During adulthood, neural stem cells with polySia-NCAMs may migrate to injured areas and promote healing.

“The landscape of the cell surface of developing cells is decorated with a bewildering array of informational-rich sugar-protein molecules of which polysialylated NCAMs are of chief importance,” explained Troy. “During the life of a cell, these surface molecules are critical to cellular proliferation, self-renewal, differentiation and survival – essential processes for normal embryonic development and tissue regeneration in adults.”

Although it was already well known that cells expressing polySia-NCAM exist in the central nervous system, this study is the first to document that they are also in the peripheral nervous system, specifically in the spiral ganglia, groups of nerve cells located in the inner ear that are essential to hearing.

Working with adult cells isolated from the inner ear spiral ganglia of guinea pigs, Troy’s team was able to show that they expressed both polySia and NCAM. The polySia component was abundantly present on neural stem cells but markedly reduced on mature cells, implicating the polySia-NCAM complex as being present on immature cells and able to serve as a biomarker to identify these cells.

“Finding polySia-NCAM – a functional biomarker that modulates neuronal differentiation – on adult inner ear neural stem cells after differentiation gives researchers a ‘handle’ to identify and isolate these cells from among the many cells taken from a patient,” said Jan Nolta, director of the UC Davis Stem Cell Program and the university’s Institute for Regenerative Cures. “This discovery will enhance research into spiral ganglion neurons and may bring treatments closer to patients with hearing deficits.”

The article is titled “Expression of polysialylated neural cell adhesion molecules on adult stem cells after neuronal differentiation of inner ear spiral ganglion neurons.”

Lead author Kyoung Ho Park, a professor at Catholic University College of Medicine in Seoul, Korea, initiated the research for this article while on sabbatical leave in Troy’s laboratory at UC Davis.

Office of the Vice Chancellor and Dean | UC Davis Health

Welcome Dr. David Lubarsky to UC Davis Health!

David A. LubarskyUC Davis Chancellor Gary May has appointed David A. Lubarsky to the position of vice chancellor of human health sciences and chief executive officer of UC Davis Health, which includes the School of Medicine, the Betty Irene Moore School of Nursing, the 1,000-member physician practice group, and UC Davis Medical Center, a 627-bed acute-care hospital. Lubarsky will join UC Davis on July 2, 2018.

Lubarsky most recently served as the chief medical and systems integration officer with the University of Miami Health System, a position he has held since 2012. As a leader within the system, he has overseen the system’s four hospital and practice chief medical officers as well as patient safety and quality. In addition, he led the university’s self-insured malpractice program, which focuses on prevention, and patient and visitor services, including patient experience. During his tenure at the University of Miami, Lubarsky integrated programs to create system-wide consistent approaches to care and quality improvement, including a new central safety and quality office, a system-wide safety and quality governing board, a system-wide chief medical officer council, a system-wide infection control and antibiotic stewardship program, and a central PI and project management office.

"David brings to UC Davis broad experience and proven results in a major healthcare market," May said. "He has an impressive record of sound financial management and innovative practices for a high functioning health care system that has gained national attention. His success in raising funds to meet pressing needs, including for enhanced access to Medicaid and indigent patients, aligns well with our values at UC Davis Health."

Lubarsky has been recognized for his success in helping establish a centralized scheduling system, improving infrastructure, and improving performance across many areas of the University of Miami health system. He raised more than $100 million annually for the University of Miami from state and federal funding sources to aid enhanced access for Medicaid and indigent patients. Previously, as CEO of the 1,100-physician practice, he turned a $100 million loss into a $32 million surplus in one year by growing patient volumes and optimizing the revenue cycle while making sure already high patient experience scores were maintained. Of note, every one of his major initiatives has explicitly prioritized quality and empathetic patient care.

In his efforts to meet community needs, Lubarsky has worked with the state of Florida and Centers for Medicare & Medicaid Services to expand access to Medicaid, forging a close partnership with the other major academic centers in Florida in pursuit of this goal. He has also been working with Florida’s state and congressional representatives to expand existing graduate medical education programs that would best meet the state’s needs and to secure the necessary federal funding which has been frozen for more than 20 years.

For the last 16 years, Lubarsky has been chief of service of anesthesia and pain management for the largest safety net hospital in the U.S., Jackson Memorial Hospital. He served on their board overseeing safety and quality, and throughout his tenure has been a forceful advocate for a uniform high quality of care.

"It is a privilege to join this highly regarded, progressive and nationally recognized health system," Lubarsky said. "I look forward to working closely with the accomplished faculty and staff, and routinely interacting with Davis’ talented students and trainees. I have already heard many great ideas about how to catapult Davis to greater heights, and I hope to harness those ideas to catalyze innovation so that we better serve our patients, our local community and our academic mission."
