STEM Model of Medicine

by Dhanjoo Ghista 

 

1.   Biomedical Engineering formulation of Anatomy, Physiology, Medicine and Surgery: 


Through biomedical engineering science analysis of anatomical structures, physiological and organ systems, medical tests data, and surgical procedures, we have developed new insights in: 


(i)     Anatomy, in how anatomical structures are intrinsically optimally designed for their functional performance, as for example hyperboloid shape of the vertebral body and ellipsoidal shape of left ventricle. 

(ii)   Physiology, in quantifying physiological systems and developing indices for their function and dysfunction, leading to precision medical diagnostics, such as cardiac contractility index for risk of heart failure. 

(iii)  Medicine, by developing biomedical engineering formulation of medical diagnostic and assessment methods and indices, including a new concept of non-dimensional indices in medical assessment, such as diabetic index. 

(iv)  Surgery, involving customized biomedical engineering analysis of surgical procedures (such as of coronary bypass surgery), and design of prosthetic devices (such as vertebral body cage for fractured vertebral body, to preserve its intrinsic hyperboloid shape). 

Together, they can provide a more rigorous and precision formulation of medicine, which can be incorporated into the medical curriculum and then also in clinical care.

3. What is needed for Medicine, towards precision medicine for the best treatment outcomes:

It is our objective to (i) make medicine more precise in its diagnosis, (ii) improve the outcomes of medical/surgical procedures, and (iii) patency of surgical procedures, implants and prostheses.   

For this purpose, we need to make Medical sciences more precise, so that they can be translated into more reliable medical and surgical procedures.  Now medical sciences, such as anatomy, physiology, biochemistry, microbiology, molecular biology, pharmacology are also undergoing transformation into more scientific and mathematically oriented disciplines.   For example, physiology can be taught as physiological physics, anatomy can be taught as anatomical engineering, biology subjects can be taught as systems biology and mathematical biology.

 

In other words, we need to incorporate the full scope of STEM subjects into Medicine, into both medical sciences and clinical sciences.  

 

 

4.  Modern Medical Curriculum, to educate scientific and technological doctors to offer the best healthcare to their patients:

Many medical schools have started to develop a new medical curriculum, for the next generation of primary care physicians. This curriculum provides an education that integrates formal classroom-based medical science knowledge with patient-centered and disease-focused medical education.  Essentially the new curriculum features foundational medical sciences courses integrated with early engagement with patients and clinical training, involving teaching medical students about the health care system, and how to integrate use of technology into the practice of medicine. The four inter-woven pillars of this new medical curriculum are Health Systems Sciences, Medical Sciences, Healthcare Informatics, and Clinical Sciences.  The shift in this new curriculum is to make students more informed about healthcare delivery. 

 

However, this modern curriculum does not make for precision medicine and to educate a new generation of smart medical doctors with the competency to apply all the modern STEM disciplines into clinical practice.  In fact, in this modern medical curriculum there has still remained the need for engineering-physics-mathematics incorporation into medical sciences and biomedical engineering incorporation into clinical sciences, in order to cultivate knowledge for more quantitative medical and clinical sciences leading to more precise medical and surgical procedures—which is where medicine is headed in the 21st century.  

 

For this purpose, we are proposing the following MD-PhD (Medical & Surgical Engineering) Program, to be offered in the School of Medicine, in collaboration with the Biomedical Engineering Department. 

 

5.  MD-PhD (Medical & Surgical Engineering) Program (to be offered in the School of Medicine):

With the help of the Biomedical Engineering Department, the PhD component of this novel program will consist of Courses in:


1.   Physiological Engineering:

·      Physics and Engineering formulations of Physiological Systems

2. Medical Diagnostics:

·      Signal and Image Processing, Medical Diagnostic Apps.

3. Medical Engineering: 

·      Cardiological and Cardiac Surgical Engineering, Renal Engineering, Neurological Engineering, Orthopedic and Spinal Surgical Biomechanics, Rehabilitation Engineering. 

4. Surgical Engineering: 

·      Cardiac Surgical Engineering (in coronary stenting and bypass surgery), 

·      Orthopedic and Spinal Surgical Engineering (of bone fracture fixation, joint replacement, and spinal fracture fixation),

involving computerized surgical simulation to analyze and plan patient-specific surgical procedures for obtaining optimal outcomes.

 

This Program will educate new set of smart medical doctors, who are learned in biomedical engineering formulations of medical systems and surgical procedures, and are able to implement them in clinical care.  



6.  Promoting significant advances in Medical education, teaching, research and practice, through my textbooks:

I am now providing some insights into my recent textbooks which are designed to be developers and transcribers of new medical knowledge and concepts into medical education and learning. For that purpose, I have attached information on my following three books:

(i)   Cardiology Science and Technology (Taylor and Francis) designed as computational format of Cardiology, involving (i) left ventricular wall stress, contractility and vector cardiogram, and (ii) aortic and coronary blood flow and customized coronary bypass surgery.


(ii)  Biomedical Science, Engineering and Technology (InTech publishers), integrates biomedical science, biomaterials and implants, biomedical engineering, biotechnology, physiological engineering, and hospital management science and technology. Together, these topics are incorporating STEM into translational medicine. 


(iii)  Computational and Mathematical Methods in Cardiovascular Physiology (World Scientific), which has transformed cardiovascular physiology into a STEM discipline.


Together, these books are providing a gateway for this new emerging scenario of (i) science and engineering based medical educational curriculum, and (ii) technologically oriented medical and surgical procedures. 

 

I am now also launching a new Book Series on Biomedical Engineering in Translational Medicine, with the Institute of Physics. This book series will provide the textbooks needed for both the Biomedical Engineering Department and this new format of School of Medicine. 

 

7.  New Era School of Medicine: 

Together, this will help develop a new era school of Medicine.
