In addition to serving as an adjunct faculty member at Logan, Dr. Napadow has been a research collaborator with Norman Kettner, DC, DACBR, FICC, chair of Logan’s Department of Radiology, for nearly 20 years.

 

According to Elizabeth A. Krupinski, PhD, co-chair of the Council of Distinguished Investigators, the award recipients represent the future of research in radiology, advancing the field and developing ways to significantly improve patient care through imaging.

 

Each of the honorees has met the following criteria:

  • Primary professional appointment in an academic Department of Radiology;
  • Recipient of a MD, DO, and/or PhD degree;
  • Academic rank of at least Associate Professor or its equivalent;
  • Significant research contributions;
  • Sustained productivity, including at least 25 peer-reviewed scientific research publications in which the awardee is the first author or senior author; and
  • Demonstrated accomplishments as an independent investigator with a substantial ongoing research program, including at least 6 cumulative years of funding as the Principal Investigator of a major competitive extramural research grant.

Honorees will be inducted into the Academy’s Council of Distinguished Investigators during a ceremony that will be held in November at the Radiological Society of North America’s 2019 annual meeting in Chicago.


Neuromodulation Journal Publishes Logan Research

March 21, 2019 -- Brain Stimulation, a premier journal for original research in the field of neuromodulation, has published research co-authored by Norman W. Kettner, DC, DACBR, DCBCN, FICC, chair of Logan’s Department of Radiology.

The study looked at the vagus nerve, which originates in the brain stem and is responsible for a variety of systems operations in the body, including the cardiovascular, immune and metabolic. Specifically, Dr. Kettner’s research wanted to determine if targeting vagal nuclei in response to stimulation was enhanced when the stimulation was delivered during exhalation.

To find out, researchers used a multimodal ultrahigh-field (7T) fMRI to examine vagal nuclei in the brain stem while applying a respiratory-gaited auricular vagal afferent nerve stimulation (RAVENS) technique. The transcutaneous electrical stimulation was applied in the ear at the cymba conchae. The results demonstrated that targeting was indeed enhanced during exhalation. This work will translate to nonpharmacological approaches for modulating brain activity in chronic pain and other neurological conditions.

Dr. Kettner’s co-researchers included Roberta Sclocco, PhD, and Vitaly Napadow, PhD, who are affiliated with Logan University, Department of Radiology through the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital.

Dr. Kettner said he was honored to have research accepted by Brain Stimulation. “The journal focuses on research that promises to noninvasively modulate the nervous system and function of the brain,” he said. “Our research achieved that, and offers a brand new field of study.”


 


Logan’s College of Chiropractic Establishes Preceptorship Program with The Medical College of Wisconsin

November 27, 2018 -- Logan’s College of Chiropractic has entered into an affiliation agreement to establish a preceptorship program with The Medical College of Wisconsin (MCW) Department of Neurosurgery.

Under the direction of Jeff King, DC, MS, 2011 graduate of Logan University, who serves as an assistant professor at MCW, Logan student interns will receive clinical training in a high-quality patient care delivery system. The goal of the preceptorship program is to enhance patient care, education and research opportunities for both institutions. 

“We are very excited to expand the number of schools participating in our preceptorship program,” said Dr. King. “Our hope is that by offering this transdisciplinary educational opportunity we can encourage students to have an interest in reaching across professions to provide the best possible care for their patients during their clinical careers.”

During 2018, Logan placed approximately 165 student interns in preceptorship programs with organizations, institutions and private practices around the world. Preceptorships at MCW will start in May 2019 wherein eligible students will go through a selection process. 

Chair of Logan’s Department of Radiology Norman Kettner, DC, DACBR, FICC said Dr. King will bring awareness of patient-centered and cost-effective chiropractic care delivered in a multidisciplinary clinical environment, where he daily interacts across a range of specialties and disciplines.  “This clinical environment is what the future is likely to reveal: chiropractic physicians directly integrated into the health care system,” he said. 


Dr. Norman W. Kettner Published in Journal of Pain

November 13, 2018 -- Congratulations are due to Norman W. Kettner, DC, DACBR, DCBCN, FICC, chair of Logan’s Department of Radiology, whose collaborative research was published this week in Journal of Pain. 

The research explored clinical and neuroimaging responses of spinal manipulative therapy (SMT) in chronic low back pain. It demonstrates reduction of pain, expectation of pain, fear-related movement and the corresponding brain imaging responses. 

According to the study, learning and memory (implicit) processes, such as habituation, sensitization and operant conditioning, are determinants of chronic low back pain. Perception of pain takes place when potential or actual noxious stimuli are appraised as threats. Maladaptive neuroplastic structural and functional brain changes evolve from these learning processes to initiate changes in pain perception. The reversal of these maladaptive brain changes reduces chronic pain. One method of achieving this is through SMT, which generates salient sensory and proprioceptive feedback that may disrupt the relationship between pain anticipation, fear and movement.

The research was partly funded by National Chiropractic Mutual Insurance Company and was a collaboration between Logan University, Athinoula A. Martinos Center for Biomedical Imaging, the Osher Center for Integrative Medicine―a partnership between Brigham and Women’s Hospital and Harvard Medical School―and Melrose Family Chiropractic.

Chiropractic Grand Rounds Recap: Roberta Sclocco, PhD

November 9, 2018 -- This past summer, Logan welcomed Roberta Sclocco, PhD, to campus for a Chiropractic Grand Rounds presentation. Dr. Sclocco is a research fellow at Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital and Harvard Medical School. Her presentation, titled “Transcutaneous Vagus Nerve Stimulation Optimized Using Functional MRI” focused on the application and integration of advanced imaging techniques and brainstem neural science. This work is an ongoing line of research with which Norman Kettner, DC, DACBR, FICC and Chair of Logan’s Department of Radiology is a collaborator.

In an introduction to Dr. Sclocco’s presentation, Dr. Kettner explained the importance the vagus nerve plays in many major biological systems.

“The inflammatory reflex is a physiological mechanism through which the vagus nerve regulates immune function, inhibits excessive proinflammatory cytokine production and may provide a variety of biological, psychological and behavioral health benefits addressing the elements of the biopsychosocial model,” he said. “Vagus nerve signaling plays an important role in the regulation of feeding behavior, gut regulation, immune network interaction, pain modulation and metabolic homeostasis. Cholinergic signaling (inflammatory reflex) is known to alleviate obesity-associated inflammation and metabolic derangement and could be exploited for treatment of metabolic syndrome, type II diabetes mellitus and other obesity-driven disorders. “

Of particular importance to the current opioid epidemic, vagus stimulation has been shown to alter the pain memory process and free chronic pain patients from conditioned pain responses.

Dr. Sclocco describes her research as a merging of the head and the heart and an exploration of whether something useful can come out of integrating the two modalities. This research has employed subcutaneous stimulation of the vagus nerve (auricular branch) with 7 T fMRI to better understand the treatment and its underlying neural mechanisms.
